 If an Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall be
valid nevertheless. 
 A Note shall not be valid until an authorized signatory of the Trustee signs the certificate of authentication on the
Note. Such signature shall be manual. Such signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

demands in connection with the Notes.

 The Issuers shall require each Paying Agent other than the Trustee to agree in writing that each Paying Agent shall hold in trust for the benefit of the
Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, premium, if any, or interest on Notes (whether such assets have been distributed to it by the Issuers or any other obligor on the Notes), and shall notify
the Trustee in writing of any Default in making any such payment. The Issuers at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the
continuance of any Payment Default, upon written request to a Paying Agent, require such Paying Agent to forthwith distribute to the Trustee all assets so held in trust by such Paying Agent together with a complete accounting of such sums. Upon
distribution to the Trustee of all assets that shall have been delivered by either of the Issuers to the Paying Agent, the Paying Agent shall have no further liability for such assets. 
 Section 2.05. Noteholder Lists. 
 The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuers shall furnish or cause the Registrar to furnish to the Trustee on or before each February 1 and
August 1 in each year, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders which list may be conclusively relied on
by the Trustee. 
 Section 2.06. Transfer and Exchange. 
 Subject to the provisions of Sections 2.15 and 2.16 hereof, when Notes are presented to the Registrar or a co-Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal
principal amount of Notes of other denominations of the same series, the Registrar or co-Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the
Notes presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Partnership and the Registrar or co-Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing. To permit registrations of transfer and exchanges, the Issuers shall execute and the Trustee shall authenticate Notes at the Registrar’s or co-Registrar’s request. No 

  

 -28- 

 
service charge shall be made for any registration of transfer or exchange, but the Partnership may require payment of a sum sufficient to cover any transfer
tax or similar governmental charge in connection therewith payable by the transferor of such Notes (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Section 2.10, 3.06, 4.12, 4.15
or 9.06 hereof, in which event the Partnership shall be responsible for the payment of such taxes). 
 Without the prior consent of the
Partnership, the Registrar or co-Registrar shall not be required to register the transfer of or exchange any Note (i) during a period beginning at the opening of 15 days before a selection of Notes to be redeemed, (ii) selected for
redemption in whole or in part pursuant to Article 3 hereof, except the unredeemed portion of any Note being redeemed in part, or (iii) between a Record Date and the next succeeding Interest Payment Date. 
 Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Notes may be effected
only through a book entry system maintained by the Holder of such Global Note (or its principal or agent), and that ownership of a beneficial interest in the Note shall be required to be reflected in a book entry. 
 Section 2.07. Replacement Notes. 
 If a mutilated
Note is surrendered to the Trustee or if the Holder presents evidence to the satisfaction of the Partnership and the Trustee that the Note has been lost, destroyed or wrongfully taken, the Issuers shall issue and the Trustee shall authenticate a
replacement Note. An indemnity or a security bond may be required by the Partnership or the Trustee that is sufficient in the judgment of the Partnership and the Trustee to protect the Issuers, the Trustee or any Agent from any loss which any of
them may suffer if a Note is replaced. In every case of destruction, loss or theft, the applicant shall also furnish to the Partnership and to the Trustee evidence to their satisfaction of the destruction, loss or the theft of such Note and the
ownership thereof. Each of the Issuers and the Trustee may charge for its expenses in replacing a Note. In the event any such mutilated, lost, destroyed or wrongfully taken Note has become due and payable, the Issuers in their discretion may pay
such Note instead of issuing a new Note in replacement thereof. The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to replacement or payment of mutilated, lost,
destroyed or wrongfully taken Notes. 
 Every replacement Note is an additional obligation of the Issuers. 
 Section 2.08. Outstanding Notes. 
 Notes
outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, and those described in this Section 2.08 as not outstanding. 
 If a Note is replaced pursuant to Section 2.07 hereof (other than a mutilated Note surrendered for replacement), it ceases to be outstanding until
the Partnership and the Trustee receive proof satisfactory to each of them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to
Section 2.07 hereof. 
  

 -29- 

 If by 11:00 a.m., New York City time, on a Redemption Date or the Maturity Date, the Paying Agent holds
U.S. Dollars sufficient to pay all of the principal and interest due on the Notes on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue. 
 Section 2.09. Treasury Notes. 
 In determining
whether the Holders of the required principal amount of Notes have concurred in any direction, waiver, consent or notice, Notes owned by the Issuers or any of its Affiliates shall be considered as though they are not outstanding, except that for the
purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so considered. The Issuers shall notify the
Trustee, in writing, when it or any of its Affiliates repurchases or otherwise acquires Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired. 
 Section 2.10. Temporary Notes. 
 Until definitive Notes are ready for delivery, the Partnership
may prepare and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Partnership in the form of an Officers’ Certificate. The Officers’ Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Partnership considers appropriate for temporary Notes. Without
unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate upon receipt of a written order of the Issuers pursuant to Section 2.02 definitive Notes in exchange for temporary Notes. 
 Section 2.11. Cancellation. 
 The Partnership at
any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee, or at the direction of the
Trustee, the Registrar or the Paying Agent, and no one else, shall cancel and, at the written direction of the Partnership, dispose of and deliver evidence of such disposal of all Notes surrendered for registration of transfer, exchange, payment or
cancellation in accordance with their then existing procedures therefor. Subject to Section 2.07 hereof, the Issuers may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Partnership
shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this
Section 2.11. In no event shall the Trustee be required to destroy cancelled Notes. 
 Section 2.12. Defaulted Interest. 
 The Issuers shall pay interest on overdue principal (including post-petition interest in a proceeding under Bankruptcy Law) at the rate of interest then
borne by the Notes. The Issuers shall, to the extent lawful, pay interest on overdue installments of interest (without regard to any applicable grace periods) at the rate of interest then borne by the Notes. 
 If the Issuers default in a payment of interest on the Notes, they shall pay the defaulted interest, plus (to the extent lawful) any interest payable on
the defaulted interest to the Persons who are Holders on a subsequent special record date, which date shall be the fifteenth day next preceding the date 

  

 -30- 

 
fixed by the Issuers for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 15 days before
the subsequent special record date, the Partnership shall mail to each Holder, as of a recent date selected by the Partnership, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of
defaulted interest, and interest payable on such defaulted interest, if any, to be paid. 
 Notwithstanding the foregoing, any interest which
is paid prior to the expiration of the 30-day period set forth in Section 6.01(a) hereof shall be paid to Holders as of the Record Date for the Interest Payment Date for which interest has not been paid. 
 Section 2.13. Deposit of Moneys. 
 By 11:00 a.m.,
New York City time, on each Interest Payment Date, Redemption Date, Change of Control Payment Date, Net Proceeds Offer Payment Date and Maturity Date, the Issuers shall have deposited with the Paying Agent in immediately available funds U.S. Dollars
sufficient to make payments, if any, due on such Interest Payment Date, Redemption Date, Change of Control Payment Date, Net Proceeds Offer Payment Date or Maturity Date, as the case may be, in a timely manner which permits the Trustee to remit
payment to the Holders on such Interest Payment Date, Redemption Date, Change of Control Payment Date, Net Proceeds Offer Payment Date or Maturity Date, as the case may be. The principal and interest on Global Notes shall be payable to the
Depository or its nominee, as the case may be, as the sole registered owner and the sole Holder of the Global Notes represented thereby. The principal and interest on Notes in certificated form shall be payable at the office of the Paying Agent in
the Borough of Manhattan, the City and State of New York. 
 Section 2.14. CUSIP Number. 
 The Issuers in issuing the Notes may use “CUSIP,” “ISIN” or such other numbers, and if so, the Trustee shall use such CUSIP, ISIN or
such other numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or such other numbers printed in
the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Partnership shall promptly notify the Trustee of any change in the CUSIP, ISIN or such other number. 
 Section 2.15. Book-Entry Provisions for Global Notes. 
 (a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and (iii) bear legends as set forth in
Section 2.17 hereof. 
 Members of, or participants in, the Depository (“Agent Members”) shall have no rights under
this Indenture with respect to any Global Note held on their behalf by the Depository or under the Global Note, and the Depository may be treated by the Issuers, the Trustee and any agent of the Issuers or the Trustee as the absolute owner of the
Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the Trustee or any agent of the Issuers or the Trustee from giving effect to any written certification, proxy or other authorization
furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder. 
  

 -31- 

 (b) Interests of beneficial owners in the Global Notes may be transferred or exchanged for Certificated
Notes in accordance with the rules and procedures of the Depository and the provisions of Section 2.16 hereof. In addition, Certificated Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in Global
Notes if (i) the Depository (x) notifies the Issuers that it is unwilling or unable to continue as Depository for any Global Note or (y) has ceased to be a clearing company registered under the Exchange Act and, in each case, a
successor depositary is not appointed by the Issuers within 90 days of such notice or (ii) the Issuers so elect and the Registrar has received a written request from the Issuers to issue Certificated Notes. 
 (c) In connection with the transfer of Global Notes as an entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to be
surrendered to the Trustee for cancellation, and the Issuers shall execute, and the Trustee shall, upon receipt of an authentication order from the Issuers in the form of an Officers’ Certificate, authenticate and deliver, to each beneficial
owner identified by the Depository in writing in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount of Certificated Notes of authorized denominations. 
 (d) Any Certificated Note constituting a Restricted Security delivered in exchange for an interest in a Global Note pursuant to paragraph (b) or
(c) shall, except as otherwise provided by Section 2.16 hereof, bear the Private Placement Legend. 
 (e) The Holder of any Global
Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes. 
 Section 2.16. Registration of Transfers and Exchanges. 
 (a) Transfer and Exchange of Certificated Notes. When Certificated Notes are presented to the Registrar or co-Registrar with a request: 
 (i) to register the transfer of the Certificated Notes; or 
 (ii) to exchange such
Certificated Notes for an equal principal amount of Certificated Notes of other authorized denominations, 
 the Registrar or co-Registrar shall register the
transfer or make the exchange as requested if the requirements under this Indenture as set forth in this Section 2.16 for such transactions are met; provided, however, that the Certificated Notes presented or surrendered for registration
of transfer or exchange: 
 (I) shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory
to the Registrar or co-Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and 
 (II)
in the case of Certificated Notes the offer and sale of which have not been registered under the Securities Act and are presented for transfer or exchange prior to (x) the date which is two years after the later of the date of original issue
and the last date on which either Issuer or any of their respective Affiliates was the owner of such Note, or any predecessor thereto and (y) such later date, if any, as may be required by any subsequent change in applicable law (the
“Resale Restriction Termination Date”), such Certificated Notes shall be accompanied, in the sole discretion of the Issuers, by the following additional information and documents, as applicable: 
 (A) if such Certificated Note is being delivered to the Registrar or co-Registrar by a Holder for registration in the name of such Holder,
without transfer, a certification to that effect (substantially in the form of Exhibit B hereto); or 
  

 -32- 

 (B) if such Certificated Note is being transferred to a Qualified Institutional Buyer in
accordance with Rule 144A, a certification to that effect (substantially in the form of Exhibit B hereto); or 
 (C) if
such Certificated Note is being transferred in reliance on Regulation S, delivery of a certification to that effect (substantially in the form of Exhibit B hereto) and a transferor certificate for Regulation S transfers substantially in the
form of Exhibit D hereto; or 
 (D) if such Certificated Note is being transferred to an Institutional Accredited
Investor, delivery of certification to that effect (substantially in the form of Exhibit B hereto), certificates of the transferee in substantially the form of Exhibit C and, at the option of the Issuers in the case of transfers of
Notes with an aggregate principal amount of less than $250,000, an Opinion of Counsel reasonably satisfactory to the Issuers to the effect that such transfer is in compliance with the Securities Act; or 
 (E) if such Certificated Note is being transferred in reliance on Rule 144 under the Securities Act, delivery of a certification to that
effect substantially in the form of Exhibit B hereto) and, at the option of the Issuers, an Opinion of Counsel reasonably satisfactory to the Issuers to the effect that such transfer is in compliance with the Securities Act; or 
 (F) if such Certificated Note is being transferred in reliance on another exemption from the registration requirements of the Securities
Act, a certification to that effect (substantially in the form of Exhibit B hereto) and, at the option of the Issuers, an Opinion of Counsel reasonably satisfactory to the Issuers to the effect that such transfer is in compliance with the
Securities Act. 
 (b) Restrictions on Transfer of a Certificated Note for a Beneficial Interest in a Global Note. A Certificated Note
may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Registrar or co-Registrar of a Certificated Note, duly endorsed or accompanied by appropriate
instruments of transfer, in form satisfactory to the Registrar or co-Registrar, together with: 
 (A) in the case of
Certificated Notes, the offer and sale of which have not been registered under the Securities Act and which are presented for transfer prior to the Resale Restriction Termination Date, certification, substantially in the form of Exhibit B
hereto, that such Certificated Note is being transferred (I) to a Qualified Institutional Buyer or (1I) in an offshore transaction in reliance on Regulation S (and, in the case of this clause 11, the Issuers shall have received a
transferor certificate for Regulation S transfers substantially in the form of Exhibit D hereto; and 
  

 -33- 

 (B) written instructions from the Holder thereof directing the Registrar or co-Registrar
to make, or to direct the Depository to make, an endorsement on the applicable Global Note to reflect an increase in the aggregate amount of the Notes represented by the Global Note, 
 then the Registrar or co-Registrar shall cancel such Certificated Note and cause, or direct the Depository to cause, in accordance with the standing instructions and procedures existing between the Depository and the
Registrar or co-Registrar, the principal amount of Notes represented by the applicable Global Note to be increased accordingly. If no Global Note representing Notes held by Qualified Institutional Buyers or Persons acquiring Notes in offshore
transactions in reliance on Regulation S, as the case may be, is then outstanding, the Issuers shall issue and the Trustee shall, upon receipt of an authentication order in the form of an Officers’ Certificate in accordance with
Section 2.02, authenticate such a Global Note in the appropriate principal amount. 
 (c) Transfer and Exchange of Global Notes.
The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depository
therefor. Upon receipt by the Registrar or co-Registrar of written instructions, or such other instruction as is customary for the Depository, from the Depository or its nominee, requesting the registration of transfer of an interest in a Rule 144A
Global Note or Regulation S Global Note, as the case may be, to another type of Global Note, together with the applicable Global Notes (or, if the applicable type of Global Note required to represent the interest as requested to be transferred is
not then outstanding, only the Global Note representing the interest being transferred), the Registrar or co-Registrar shall cancel such Global Notes (or Global Note) and the Issuers shall issue and the Trustee shall, upon receipt of an
authentication order in the form of an Officers’ Certificate in accordance with Section 2.02, authenticate new Global Notes of the types so cancelled (or the type so cancelled and applicable type required to represent the interest as
requested to be transferred) reflecting the applicable increase and decrease of the principal amount of Notes represented by such types of Global Notes, giving effect to such transfer. If the applicable type of Global Note required to represent the
interest as requested to be transferred is not outstanding at the time of such request, the Issuers shall issue and the Trustee shall, upon written instructions from the Issuers in accordance with Section 2.02, authenticate a new Global Note of
such type in principal amount equal to the principal amount of the interest requested to be transferred. 
 (d) Transfer of a Beneficial
Interest in a Global Note for a Certificated Note. (i) Any Person having a beneficial interest in a Global Note may upon request exchange such beneficial interest for a Certificated Note. Upon receipt by the Registrar or co-Registrar of
written instructions, or such other form of instructions as is customary for the Depository, from the Depository or its nominee on behalf of any Person having a beneficial interest in a Global Note and upon receipt by the Trustee of a written order
or such other form of instructions as is customary for the Depository or the Person designated by the Depository as having such a beneficial interest containing registration instructions and, in the case of any such transfer or exchange of a
beneficial interest in Notes the offer and sale of which have not been registered under the Securities Act and which Notes are presented for transfer or exchange prior to the Resale Restriction Termination Date, the following additional information
and documents: 
 (A) if such beneficial interest is being transferred to the Person designated by the Depository as being the
beneficial owner, a certification from such Person to that effect (substantially in the form of Exhibit B hereto); or

 (B) if such beneficial interest is being transferred to a Qualified Institutional Buyer
in accordance with Rule 144A, a certification to that effect (substantially in the form of Exhibit B hereto); or 
 (C)
if such beneficial interest is being transferred in reliance on Regulation S, delivery of a certification to that effect (substantially in the form of Exhibit B hereto) and a transferor certificate for Regulation S transfers substantially in
the form of Exhibit D hereto; or 
 (D) if such beneficial interest is being transferred to an Institutional Accredited
Investor, delivery of certification (substantially in the form of Exhibit B hereto), a certificate of the transferee in substantially the form of Exhibit C and, at the option of the Issuers in the case of transfers of Notes with an
aggregate principal amount of less than $250,000, an Opinion of Counsel reasonably satisfactory to the Issuers to the effect that such transfer is in compliance with the Securities Act; or 
 (E) if such beneficial interest is being transferred in reliance on Rule 144 under the Securities Act, delivery of a certification to that
effect (substantially in the form of Exhibit B hereto) and, at the option of the Issuers, an Opinion of Counsel reasonably satisfactory to the Issuers to the effect that such transfer is in compliance with the Securities Act; or 

(F) if such beneficial interest is being transferred in reliance on another exemption from the registration requirements of the
Securities Act, a certification to that effect (substantially in the form of Exhibit B hereto) and, at the option of the Issuers, an Opinion of Counsel reasonably satisfactory to the Issuers to the effect that such transfer is in compliance
with the Securities Act, 
 then the Registrar or co-Registrar will cause, in accordance with the standing instructions and procedures existing between the
Depository and the Registrar or co-Registrar, the aggregate principal amount of the applicable Global Note to be reduced and, following such reduction, the Issuers will execute and, upon receipt of an authentication order in the form of an
Officers’ Certificate in accordance with Section 2.02 hereof, the Trustee will authenticate and deliver to the transferee a Certificated Note in the appropriate principal amount. 
 (ii) Certificated Notes issued in exchange for a beneficial interest in a Global Note pursuant to this Section 2.16(d) hereof shall be registered in
such names and in such authorized denominations as the Depository, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Registrar or co-Registrar in writing. The Registrar or co-Registrar shall deliver
such Certificated Notes to the Persons in whose names such Certificated Notes are so registered. 
 (e) Restrictions on Transfer and
Exchange of Global Notes. Notwithstanding any other provisions of this Indenture, a Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or

 (f) Private Placement Legend. Upon the transfer, exchange or replacement of Notes not bearing the Private Placement Legend, the Registrar or co-Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the
transfer, exchange or replacement of Notes beating the Private Placement Legend, the Registrar or co-Registrar shall deliver only Notes that bear the Private 

  

 -35- 

 
Placement Legend unless, and the Trustee is hereby authorized to deliver Notes without the Private Placement Legend if, (i) the Resale Restriction
Termination Date shall have occurred, (ii) there is delivered to the Trustee an Opinion of Counsel reasonably satisfactory to the Issuers and the Trustee to the effect that neither such legend nor the related restrictions on transfer are
required in order to maintain compliance with the provisions of the Securities Act or (iii) such Note has been sold pursuant to an effective registration statement under the Securities Act. 
 (g) General. By its acceptance of any Note bearing the Private Placement Legend, each Holder of such a Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as provided in this Indenture. 
 None of the Issuers, the Trustee, any agent of the Issuers or the Trustee (including any Paying Agent or Registrar) will have any responsibility or liability for any aspect of the records relating to or payments made
on account of beneficial ownership interests of a global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members or beneficial owners of interest in any Global Note) other than to require delivery of such
certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements hereof. 
 The Registrar shall retain copies of all letters, notices and other written communications received pursuant to
Section 2.15 hereof or this Section 2.16. The Issuers shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the
Registrar. 
 Section 2.17. Restrictive Legends. 
 Each Global Note and Certificated Note that constitutes a Restricted Security shall bear the following legend (the “Private Placement Legend”) on the face thereof until the Resale Restriction
Termination Date, unless otherwise agreed to by the Issuers and the Holder thereof: 
 THIS SECURITY (OR ITS PREDECESSOR) HAS
NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF,
U.S. PERSONS, EXCEPT AS SET FORTH IN THE NEXT SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER: 
 (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) (A “QIB”), (B) IT IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH
REGULATION S UNDER THE SECURITIES ACT, OR (C) IT IS AN INSTITUTIONAL “ACCREDITED INVESTOR” (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN “IAI”); 
  

 -36- 

 (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO
THE PARTNERSHIP OR ANY OF ITS SUBSIDIARIES, (B) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (C) IN AN OFFSHORE
TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR 904 OF REGULATION S UNDER THE SECURITIES ACT, (D) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT, (E) TO AN IAI THAT, PRIOR TO SUCH TRANSFER, FURNISHES THE
TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE TRANSFER OF THIS SECURITY (THE FORM OF WHICH CAN BE OBTAINED FROM THE TRUSTEE) AND, IF SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE PRINCIPAL AMOUNT OF
SECURITIES LESS THAN $250,000, AN OPINION OF COUNSEL ACCEPTABLE TO THE PARTNERSHIP, IF THE ISSUERS SO REQUEST, THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT, (F) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE ISSUERS, IF THE ISSUERS SO REQUEST), OR (G) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND, IN EACH CASE, IN ACCORDANCE
WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION; AND 
 (3) AGREES
THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY OR AN INTEREST HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. 
 AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION” AND “UNITED STATES” HAVE THE MEANINGS GIVEN TO THEM BY RULE 902 OF REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE GOVERNING THIS SECURITY
CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS SECURITY IN VIOLATION OF THE FOREGOING. 
 Each Global
Note shall also bear the following legend (the “Global Note Legend”): 
 THIS NOTE IS A GLOBAL NOTE WITHIN
THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY OR A NOMINEE OF A DEPOSITORY OR A SUCCESSOR DEPOSITORY. THIS NOTE IS NOT EXCHANGEABLE FOR NOTES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE
DEPOSITORY OR ITS NOMINEE EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS NOTE (OTHER THAN A TRANSFER OF THIS NOTE AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY OR BY A NOMINEE OF THE 

  

 -37- 

 
DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY) MAY BE REGISTERED EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

 TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, AND TRANSFERS OF INTERESTS IN THIS
GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN SECTION 2.16 OF THE INDENTURE. 
 ARTICLE 3

 REDEMPTION 
 Section 3.01. Notices to
Trustee. 
 If the Issuers elect to redeem Notes pursuant to paragraph 5 of the Notes, at least 15 days prior to the date on which the
Partnership notifies the Holders or during such other period as the Trustee may agree to, the Partnership shall notify the Trustee in writing of the Redemption Date, the principal amount of Notes to be redeemed and the Redemption Price, and deliver
to the Trustee an Officers’ Certificate stating that such redemption will comply with the conditions contained herein and in the Notes, as appropriate. 
 Section 3.02. Selection of Notes To Be Redeemed. 
 In the event that less than all of the Notes are to be redeemed at
any time, selection of the Notes to be redeemed shall be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed or, if such Notes are not then listed on a
national security exchange, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate; provided, however, that no Notes of a principal amount of $2,000 or less shall be redeemed in part;
provided, further, that if a partial redemption is made with the proceeds of any Qualified Equity Offering, selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as
nearly a pro rata basis as is practicable (subject to the procedures of the Depository), unless such method is otherwise prohibited. 
 Section 3.03. Notice of Redemption. 
 Notice of redemption shall be mailed by the Partnership (or at the request of the
Partnership, by the Trustee) by first class mail at least 30 but not more than 60 days before the Redemption Date to each Holder to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a
Redemption Date if the notice is issued in connection with a satisfaction and discharge of this Indenture. 
 The notice shall identify the
Notes to be redeemed (including the CUSIP, ISIN or other number(s) thereof) and shall state: 
 (1) the Redemption Date;

portion of the principal amount (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of such Note to be redeemed and that, on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal
to the unredeemed portion thereof will be issued; 
 (4) the name, address and telephone number of the Paying Agent;

Section 7.9 of the Oilfield Holdings Partnership Agreement in effect as of the Issue Date and to be paid to partners of Oilfield Holdings pursuant to Section 6.3 of the Oilfield Holdings Partnership Agreement in effect as of the Issue Date

 Section 4.12. Limitations on Asset Sales. 
 (a) The Partnership shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless: 
 (1) the Partnership or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market
Value of the assets included in such Asset Sale; and 
 (2) at least 75% of the total consideration received by the
Partnership and its Restricted Subsidiaries in such Asset Sale and in all other Asset Sales since the Issue Date consists of cash or Cash Equivalents. 
 For purposes of Section 4.12(a)(2), the following shall be deemed to be cash: 
 (a) the
amount (without duplication) of any Indebtedness (other than Subordinated Indebtedness) of the Partnership or such Restricted Subsidiary that is expressly assumed by the transferee of any such assets pursuant to (i) a written novation agreement
that releases the Partnership or such Restricted Subsidiary from further liability therefor or (ii) an assignment agreement that includes, in lieu of such a release, the agreement of the transferee or its parent company to indemnify and hold
harmless the Partnership or such Restricted Subsidiary from and against any loss, liability or cost in respect of such assumed liability, 
  

 -50- 

 (b) the amount of any obligations received from such transferee that are within 30 days

is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Partnership or (iii) a combination of (i) and (ii). 
 (b) If at any time any non-cash consideration received by the Partnership or any Restricted Subsidiary, as the case may be, in connection with any Asset
Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the
date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this Section 4.12. 
 (c) Any
Asset Sale pursuant to a condemnation, appropriation or other similar taking, including by deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a Permitted Lien or exercise by the related lienholder of rights with
respect thereto, including by deed or assignment in lieu of foreclosure shall not be required to satisfy the conditions set forth in Section 4.12(a)(1) and (a)(2). 
 (d) If the Partnership or any Restricted Subsidiary engages in an Asset Sale, the Partnership or such Restricted Subsidiary shall, no later than 365 days following the consummation thereof, apply all or any of the Net
Available Proceeds therefrom to: 
 (i) satisfy all mandatory repayment obligations under the Credit Facilities arising by
reason of such Asset Sale, and in the case of any such repayment under any revolving credit facility, effect a permanent reduction in the availability under such revolving credit facility; 
 (ii) repay any Indebtedness that was secured by the assets sold in such Asset Sale; and/or 
 (iii)(A) make any capital expenditure or otherwise invest all or any part of the Net Available Proceeds thereof in the purchase of assets
(other than securities and current assets) to be used by the Partnership or any Restricted Subsidiary in the Permitted Business, (B) acquire Qualified Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a
Permitted Business that shall become a Restricted Subsidiary immediately upon the consummation of such acquisition or (C) a combination of (A) and (B).

 (f) When the aggregate amount of Excess Proceeds equals or exceeds $15.0 million, the Partnership shall be required to make an offer to purchase from all
Holders and, if applicable, purchase or redeem (or make an offer to do so) any Pari Passu Indebtedness of the Partnership the provisions of which require the Partnership to purchase or redeem such Indebtedness with the proceeds from any Asset Sales
(or offer to do so), in an aggregate principal amount of Notes and such Pari Passu Indebtedness equal to the amount of such Excess Proceeds as follows: 
  

 -51- 

 (1) the Partnership will (a) make an offer to purchase (a “Net Proceeds
Offer”) to all Holders in accordance with the procedures set forth in this Indenture, and (b) purchase or redeem (or make an offer to do so) any such other Pari Passu Indebtedness, pro rata in proportion to the respective principal
amounts of the Notes and such other Indebtedness required to be purchased or redeemed, the maximum principal amount of Notes and Pari Passu Indebtedness that may be purchased or redeemed out of the amount (the “Payment Amount”) of
such Excess Proceeds; 
 (2) the offer price for the Notes will be payable in cash in an amount equal to 100% of the principal
amount of the Notes tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid interest thereon, if any, to the date such Net Proceeds Offer is consummated (the “Offered Price”), in accordance with the procedures set forth
in this Indenture, and the purchase or redemption price for such Pari Passu Indebtedness (the “Pari Passu Indebtedness Price”) shall be as set forth in the related documentation governing such Indebtedness; 
 (3) if the aggregate Offered Price of Notes validly tendered and not withdrawn by Holders thereof exceeds the pro rata portion of
the Payment Amount allocable to the Notes, Notes to be purchased will be selected on a pro rata basis; and 
 (4) upon
completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero. 
 (g) To the extent that the sum of the aggregate Offered Price of Notes tendered pursuant to a Net Proceeds Offer and the aggregate Pari Passu
Indebtedness Price paid to the holders of such Pari Passu Indebtedness is less than the Payment Amount relating thereto (such shortfall constituting a “Net Proceeds Deficiency”), the Partnership may use the Net Proceeds Deficiency,
or a portion thereof, for any purposes not otherwise prohibited by the provisions of this Indenture. 
 (h) Notwithstanding the foregoing,
the sale, conveyance or other disposition of all or substantially all of the assets of the Partnership and its Restricted Subsidiaries, taken as a whole, will be governed by the provisions of Section 4.15 and/or the provisions of Article 5 and
not by the provisions of this Section 4.12. 
 The Partnership shall comply with applicable tender offer rules, including the
requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations
conflict with this Section 4.12, the Partnership shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.12 by virtue of this compliance.

its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an “Affiliate Transaction”), unless: 
  

 -52- 

 (1) such Affiliate Transaction is on terms that are no less favorable to the Partnership
or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction at such time on an arm’s-length basis by the Partnership or that Restricted Subsidiary from a Person that is not an Affiliate of the
Partnership or that Restricted Subsidiary; and 
 (2) the Partnership delivers to the Trustee: 
 (a) with respect to any Affiliate Transaction involving aggregate value in excess of $5.0 million, an Officers’ Certificate
certifying that such Affiliate Transaction complies with clause (1) above and a Secretary’s Certificate which sets forth and authenticates a resolution that has been adopted by a majority of the disinterested members of the Board of
Directors of the Partnership approving such Affiliate Transaction; and 
 (b) with respect to any Affiliate Transaction
involving aggregate value of $25.0 million or more, the certificates described in the preceding clause (a) and a written opinion as to the fairness of such Affiliate Transaction to the Partnership or such Restricted Subsidiary from a financial
point of view issued by an accounting, appraisal or investment banking firm of national standing.

apply to: 
 (1) transactions exclusively between or among (a) the Partnership and one or more Restricted Subsidiaries or
(b) Restricted Subsidiaries;

(including pursuant to any employment agreement or any retirement, health, stock option or other benefit plan) and indemnification arrangements, in each case, as determined in good faith by the Partnership’s Board of Directors or senior
management; 
 (3) any Permitted Investments; 
 (4) any Restricted Payments which do not violate Section 4.11; 
 (5) (a) any agreement in effect on
the Issue Date, as in effect on the Issue Date or as thereafter amended or replaced in any manner that, taken as a whole, is not more disadvantageous to the Holders or the Partnership in any material respect than such agreement as it was in effect
on the Issue Date or (b) any transaction pursuant to any agreement referred to in the immediately preceding clause (a); 
 (6) any
transaction with a Person (other than an Unrestricted Subsidiary of the Partnership) which would constitute an Affiliate of the Partnership solely because the Partnership or a Restricted Subsidiary owns an equity interest in or otherwise controls
such Person; and 
  

 -53- 

 (7) (a) any transaction with an Affiliate where the only consideration paid by the Partnership or
any Restricted Subsidiary is Qualified Equity Interests or (b) proceeds from the issuance or sale of any Qualified Equity Interests or contributions to the capital of the Partnership. 
 Section 4.14. Limitations on Liens. 
 The
Partnership shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien securing Indebtedness (other than Permitted Liens) of any nature whatsoever against any
assets of the Partnership or any Restricted Subsidiary (including Equity Interests of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, unless contemporaneously therewith: 
 (1) in the case of any Lien securing any Indebtedness that ranks pari passu with the Notes or a Note Guarantee, effective provision is
made to secure the Notes or such Note Guarantee, as the case may be, at least equally and ratably with or prior to such Indebtedness with a Lien on the same collateral; and 
 (2) in the case of any Lien securing Subordinated Indebtedness, effective provision is made to secure the Notes or such Note Guarantee, as
the case may be, with a Lien on the same collateral that is prior to the Lien securing such Subordinated Indebtedness, 
 in each case, for so long as such
Indebtedness is secured by such Lien. 
 Section 4.15. Change of Control. 
 (a) Upon the occurrence of any Change of Control, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes as
described in paragraph 5 of the reverse of the Notes, each Holder will have the right to require that the Partnership purchase all or any portion (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of that Holder’s Notes for
a cash price (the “Change of Control Purchase Price”) equal to 101% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase, subject to the right of Holders of
record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the purchase date. 
 (b)
Within 30 days following any Change of Control, the Partnership must send by first-class mail, a notice to each Holder, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. Such notice shall state:

completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 
 (6) that Holders shall be entitled to withdraw their acceptance if the Paying Agent receives, not later than the close of business on the
third Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes delivered for purchase, and a statement that such Holder is
withdrawing his election to have such Notes purchased; 
 (7) that Holders whose Notes are being purchased only in part shall

to have breached its obligations under the provisions of this Section 4.15 by virtue thereof. 
  

 -55-

Offer following a Change of Control shall be applicable regardless of whether any other provisions of this Indenture are applicable to the transaction giving rise to the Change of Control.

Control Offer. 
 (i) Notwithstanding anything to the contrary in this Indenture, a Change of Control Offer may be made in advance of a

 (9) customary provisions in partnership agreements, limited liability company organizational
governance documents, joint venture agreements and other similar agreements entered into in the ordinary course of business that restrict the transfer of ownership interests in such partnership, limited liability company, joint venture or similar

Subsidiaries. 
 (a) The Partnership may designate any Subsidiary (other than Finance Corp., but including any newly formed or newly

 (2) the Partnership would be permitted to make, at the time of such Designation, (a) a Permitted Investment or (b) an Investment pursuant to clause (a) of Section 4.11 in either case, in an amount
(the “Designation Amount”) equal to the Fair Market Value of the Partnership’s proportionate interest in such Subsidiary on such date. 
 (b) No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless such Subsidiary: 
 (1) has no Indebtedness other than Non-Recourse Debt; 
 (2) is not party to any agreement,
contract, arrangement or understanding with the Partnership or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding are no less favorable to the Partnership or the Restricted Subsidiary than those that

 (3) is a Person with respect to which neither the
Partnership nor any Restricted Subsidiary has any direct or indirect obligation (a) to subscribe for additional Equity Interests or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any

support for any Indebtedness of the Partnership or any Restricted Subsidiary, except for any guarantee given solely to support the pledge by the Partnership or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which
guarantee is not recourse to the Partnership or any Restricted Subsidiary. 
 (c) If, at any time, any Unrestricted Subsidiary fails to meet
the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to
be incurred by a Restricted Subsidiary at such time and, if the Indebtedness is not permitted to be incurred under Section 4.10 or the Lien is not permitted under Section 4.14, the Partnership shall be in default of the applicable Section.

  

 -58- 

 (d) The Partnership may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a
“Redesignation”) only if: 
 (1) no Default shall have occurred and be continuing at the time of and after
giving effect to such Redesignation; and 
 (2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary
outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of this Indenture.

Subsidiary, or (2) any Unrestricted Subsidiary is Redesignated a Domestic Restricted Subsidiary or (3) any Foreign Restricted Subsidiary guarantees any Indebtedness of the Partnership or a Domestic Restricted Subsidiary then the
Partnership shall cause such Restricted Subsidiary to:

in respect of its Note Guarantee; and 
 (2) deliver to the Trustee one or more Opinions of Counsel that such supplemental
indenture (a) has been duly authorized, executed and delivered by such Restricted Subsidiary and (b) constitutes a valid and legally binding obligation of such Restricted Subsidiary in accordance with its terms, subject to the exceptions
set forth in Section 10.07 hereof; 
 provided, however, that a Restricted Subsidiary that owns net assets that have an aggregate Fair Market
Value of less than 1% of the Consolidated Tangible Assets of the Partnership as of the end of the previous fiscal quarter, need not become a Guarantor. 
 (b) Notwithstanding the foregoing, if, as of the end of any fiscal quarter, the Domestic Restricted Subsidiaries that are not required to be Guarantors pursuant to Section 4.20(a) collectively own net assets that
have an aggregate Fair Market Value equal to or greater than 2% of the Partnership’s Consolidated Tangible Assets, then the Partnership shall cause one or more of such non-Guarantor Domestic Restricted Subsidiaries promptly to become a
Guarantor or Guarantors such that after giving effect thereto, the total net assets owned by all such remaining non-Guarantor Domestic Restricted Subsidiaries will have an aggregate Fair Market Value of less than 2% of the Consolidated Tangible
Assets of the Partnership. Any such Domestic Restricted Subsidiary so designated must become a Guarantor and execute a supplemental indenture and deliver one or more Opinions of Counsel to the Trustee, as provided in Section 4.20(a), within 15

 Section 4.21. Limitations on Layering Indebtedness. 
 (a) The Partnership shall not, and shall not permit any Guarantor to, directly or indirectly, incur any Indebtedness that is or purports to be by its
terms (or by the terms of any agreement governing such Indebtedness) subordinated to any other Indebtedness of the Partnership or of such Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement
governing such Indebtedness) made expressly subordinate to the Notes or the Note Guarantee of such Guarantor, to the same extent and in the same manner as such Indebtedness is subordinated to such other Indebtedness of the Partnership or such
Guarantor, as the case may be. 
 (b) For purposes of the foregoing, no Indebtedness will be deemed to be subordinated in right of payment to
any other Indebtedness of the Partnership or any Guarantor solely by virtue of being unsecured or secured by a Permitted Lien or by virtue of the fact that the holders of such Indebtedness have entered into intercreditor agreements or other
arrangements giving one or more of such holders priority over the other holders in the collateral held by them. 
 Section 4.22. Restrictions on
Activities of Finance Corp. 
 Finance Corp. shall not hold any material assets, become liable for any material obligations or engage in

Partnership or one or more of the Partnership’s Restricted Subsidiaries other than Finance Corp.

failure to pay at final maturity principal on such Indebtedness within the applicable express grace period in respect of such Indebtedness at the time of such default or (B) results in the acceleration of such Indebtedness prior to its express
final maturity (which acceleration is not rescinded, annulled or otherwise cured within 30 days of receipt by the Issuers or such Restricted Subsidiary of notice of any such acceleration), and, in each case, the principal amount of such

 Section 6.02. Acceleration. 
 If an Event of Default (other than an Event of Default specified in
Section 6.01(h) or (i) with respect to the Partnership) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Partnership, or the Holders of at least 25% in aggregate principal amount of the
Notes then outstanding by written notice to the Partnership and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable. Upon such declaration of acceleration, the aggregate
principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable (a) if there is no Indebtedness outstanding under any Credit Facility at such time, immediately and (b) if otherwise, upon the earlier of
(x) the final maturity (after giving effect to any applicable grace period or extensions thereof) or an acceleration of any Indebtedness under any Credit Facility prior to the express final stated maturity thereof and (y) five Business
Days after the representative under each Credit Facility receives the acceleration declaration, but, in the case of this clause (b) only, if such Event of Default is then continuing; provided, however, that after such acceleration, but
before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of such outstanding Notes may, rescind and annul such acceleration if 
 (1) the rescission would not conflict with any judgment or decree; 
 (2) all Events of Default, other than nonpayment of principal or interest that has become due solely because of the acceleration, have
been cured or waived; 
 (3) to the extent the payment of such interest is lawful, interest on overdue installments of
interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; 
 (4)
the Partnership has paid all sums paid or advanced by the Trustee hereunder and its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances and those of its agents and counsel; and 
 (5) in the event of the cure or waiver of an Event of Default of the type described Section 6.01 (h) or (i) above, the
Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived. 
 No such
rescission shall affect any subsequent Default or impair any right consequent thereto. If an event of Default specified in Section 6.01(h) or (i) occurs with respect to the Partnership and is continuing, then all unpaid principal of,
premium, if any, and accrued and unpaid interest on all of the outstanding notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
  

 -64- 

 Section 6.03. Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or premium, if any, and interest on the Notes or
to enforce the performance of any provision of the Notes or this Indenture and may take any necessary action requested of it as Trustee to settle, compromise, adjust or otherwise conclude any proceedings to which it is a party. 
 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All
available remedies are cumulative to the extent permitted by law. 
 Section 6.04. Waiver of Past Defaults and Events of Default. 
 Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection
with an offer to purchase); provided, however, that, as provided in Section 6.02 hereof, the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including
any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
 Section 6.05. Control by Majority. 

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or exercising any trust or power conferred on it, provided the Trustee receives such indemnity or security satisfactory to it in connection therewith. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture, that the Trustee determines in good faith may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. 
 Section 6.06. Limitation on Suits. 
 Subject to
Section 6.07, no Holder shall have any right to institute any proceeding with respect to this Indenture or any remedy thereunder unless: 
 (1) such Holder has given the Trustee written notice of a continuing Event of Default; 
 (2)
the Holders of at least 25% in aggregate principal amount of outstanding Notes have made a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders offer to the Trustee security indemnity satisfactory to Trustee against any costs, liability or expense; 
  

 -65- 

 (4) the Trustee fails to institute such proceeding within 60 days after receipt of the
request and the offer of security or indemnity; and 
 (5) the Trustee has not received directions inconsistent with such
written request during such 60-day period by the Holders of a majority in aggregate principal amount of the outstanding Notes. 
 Section 6.07.
Rights of Holders To Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder to receive
payment of principal of or accrued interest of any Note held by such Holder on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute and
unconditional and shall not be impaired or affected without the consent of the Holder. 
 Section 6.08. Collection Suit by Trustee. 

If an Event of Default occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the
Issuers for the whole amount of unpaid principal, premium and accrued interest remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal and interest on overdue installments of interest, in
each case at the rate set forth in Section 4.01 hereof, and such further amounts as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel. 
 Section 6.09. Trustee May File Proofs of Claim. 
 The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes),
their creditors or their property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same after deduction of its charges and expenses to the extent
that any such charges and expenses are not paid out of the estate in any such proceedings and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan or reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceedings. 
  

 -66- 

 Section 6.10. Priorities. 
 Any money collected by the Trustee pursuant to this Article and any other money or property distributable in respect of the Issuers’ obligations under this Indenture after an Event of Default shall be applied in
the following order: 
 FIRST: to the Trustee (including any predecessor Trustee) for amounts due under Section 7.07
hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 SECOND: if the Holders are forced to proceed against the Issuers or any Guarantor directly without the Trustee, to Holders for their
collection costs; 
 THIRD: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest as
to each, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes; and 
 FOURTH: to the Issuers or, to the extent the Trustee collects any amounts from any Guarantor, to such Guarantor. 
 The Trustee,
upon prior written notice to the Issuers, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. 
 Section 6.11. Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in
any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to
a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof or a suit by Holders of more than 10% in principal amount of the Notes then outstanding.

 Within 90 days after the occurrence of any Default or Event of Default hereunder, the Trustee shall transmit by mail to Holders of Notes, as their names

 Section 7.07. Compensation and Indemnity. 
 The Issuers shall pay to the Trustee from time to
time such compensation as shall be agreed in writing between the Issuers and the Trustee for the Trustee’s services. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuers
shall reimburse the Trustee upon request for all reasonable fees and expenses, including out-of-pocket expenses incurred or made by it in connection with the performance of its duties under this Indenture or in connection with the collection of any
funds. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents and counsel. 
 The Issuers, jointly and
severally, shall indemnify each of the Trustee and its agents, employees, stockholders and directors and officers for, and hold them harmless against, any loss, liability or expense incurred by them (including attorney’s fees and expenses)
arising out of or in connection with the administration of this trust including the reasonable costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or
duties hereunder, except for such actions to the extent caused by any negligence, bad faith or willful misconduct on their part. The Trustee shall notify the Issuers promptly, in writing, of any claim asserted against the Trustee for which it may
seek indemnity. At the Trustee’s sole discretion, the Issuers shall defend the claim and the Trustee shall cooperate and may participate in the defense; provided that any settlement of a claim shall be approved in writing by the Trustee.

Notes. 
 In addition and without prejudice to the rights provided to the Trustee under any provision of this Indenture, when the Trustee
incurs expenses or renders services after an Event of Default specified in Section 6.01(h) or (i) hereof occurs, such expenses and the compensation for such services are intended to constitute expenses of administration under any
Bankruptcy Law. 
 The obligation of the Issuers under this Section 7.07 shall survive the resignation or removal of the Trustee and the
termination or satisfaction and discharge of this Indenture. The Trustee will comply with the provisions of Section 313(b)(2) of the TIA to the extent applicable. 
 “Trustee” for purposes of this Section shall include any predecessor Trustee and the Trustee in each of its capacities hereunder and to each agent, custodian and other person employed to act hereunder;

 Section 7.08. Replacement of Trustee. 
 The Trustee may resign at any time by so notifying the Issuers in writing. The Holders of a majority in principal amount of the outstanding Notes may
remove the Trustee by so notifying the Trustee and the Issuers in writing and may appoint a successor Trustee. The Issuers may remove the Trustee at their election if: 
 (a) the Trustee fails to comply with Section 7.10 hereof; 
 (b) the Trustee is adjudged a bankrupt or an insolvent; 
 (c) a receiver or other public officer takes charge of the Trustee or its property; or 
 (d) the Trustee otherwise becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Issuers shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Immediately after that, the
retiring Trustee shall transfer, after payment of all sums then owing to the Trustee pursuant to Section 7.07 hereof, all property held by it as Trustee to the successor Trustee, subject to the lien provided in Section 7.07 hereof, the
resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder.

 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Issuers or the Holders of at least 10% in principal amount of the outstanding Notes may petition, at the expense of the Issuers, any court of competent jurisdiction for the appointment of a successor Trustee. 
 If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such
Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 
 Section 7.09. Successor Trustee by Consolidation, Merger or Conversion. 
 If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, subject to this Article 7, the successor corporation without
any further act shall be the successor Trustee.

of at least $100,000,000 as set forth in its most recent published annual report of condition. If the Trustee has or shall acquire any “conflicting
interest” within the meaning of TIA Section 310(b) after a Default has occurred and is continuing, the Trustee and the Issuers shall comply with the provisions of TIA Section 310(b); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuers are outstanding if the requirements for such exclusion
set forth in TIA Section 310(b)(1) are met. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.10, the Trustee shall resign immediately in the manner and with the effect hereinbefore

 ARTICLE 8 
 AMENDMENTS, SUPPLEMENTS AND WAIVERS 
 Section 8.01. Without Consent of Holders. 
 The
Issuers, when authorized by a Board Resolution, and the Trustee may amend or supplement this Indenture, the Notes or the Note Guarantees without notice to or consent of any Holder: 
 (1) to cure any ambiguity, defect or inconsistency; 
 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes; 
 (3) to provide for the assumption of the Partnership’s obligations to the Holders in the case of a merger, consolidation or sale of
all or substantially all of the Partnership’s assets accordance with Article 5; 
 (4) to add any Note Guarantee or to
effect the release of any Guarantor from any of its obligations under its Note Guarantee or this Indenture (to the extent permitted by this Indenture); 
 (5) to make any change that would provide any additional rights or benefits to the Holders or does not materially adversely affect the rights of any Holder; 
 (6) to provide for the conversion of the Partnership into a corporation in accordance with Section 5.02(b) hereof; 
 (7) to secure the Notes or any Note Guarantees or any other obligation under this Indenture; 
 (8) to evidence and provide for the acceptance of appointment by a successor trustee; 
  

 -73- 

 (9) to conform the text of this Indenture or the Notes to any provision of the
“Description of notes” section of the Offering Memorandum to the extent that such provision in the “Description of notes” was intended to be a verbatim recitation of a provision of this Indenture, the Note Guarantees or the
Notes; or 
 (10) to provide for the issuance of Additional Notes in accordance with this Indenture. 
 Section 8.02. With Consent of Holders. 
 (a)
Subject to Section 6.07 hereof, the Issuers and the Guarantors, when each is authorized by a Board Resolution of its Board of Directors, and the Trustee may amend or supplement this Indenture or the Notes or the Note Guarantees with the written
consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding. Subject to Section 6.07 hereof, the Holders of a majority in aggregate principal amount of the outstanding Notes may waive compliance by
the Issuers, or any Guarantor with any provision of this Indenture, the Notes, or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04 hereof,
may not: 
 (1) reduce, or change the fixed maturity of, the principal of any Note; 
 (2) reduce the rate of, or extend the time for payment of, interest on any Note; 
 (3) reduce any premium payable upon redemption of the Notes or change the date on which any Notes are subject to redemption or waive
any payment with respect to the redemption of the Notes; provided, however, that solely for the avoidance of doubt, and without any other implication, any purchase or repurchase of Notes (including pursuant to Section 4.12 and
Section 4.15) shall not be deemed a redemption of the Notes; 
 (4) make any Note payable in money or currency other than
that stated in the Notes; 
 (5) modify or change any provision of this Indenture or the related definitions to affect the
ranking of the Notes or any Note Guarantee in a manner that adversely affects the Holders; 
 (6) reduce the percentage of
Holders necessary to consent to an amendment or waiver to this Indenture, the Notes or the Note Guarantees; 
 (7) waive a
default in the payment of principal of or interest on any Notes (except a rescission of acceleration of the Notes by the Holders thereof as provided in this Indenture and a waiver of the payment default that resulted from such acceleration);

 (8) impair the rights of Holders to receive payments of principal of or interest on the Notes on or after the due date
therefor or to institute suit for the enforcement of any payment on the Notes; 
 (9) release any Guarantor that is a
Significant Subsidiary from any of its obligations under its Note Guarantee or this Indenture, except as permitted by this Indenture; or 
 (10) make any change in these amendment, supplement and waiver provisions. 
  

 -74- 

 The consent of the Holders of the Notes is not necessary under this Indenture to approve the particular
form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver. 
 After an amendment or supplement under this Indenture becomes effective (other that one pursuant to Section 8.01 (4) hereof), the Partnership is required to mail to Holders of the Notes a notice briefly
describing such amendment or supplement. However, the failure to give such notice to all Holders of the Notes, or any defect therein, will not impair or affect the validity of the amendment or supplement. 
 Section 8.03. Compliance with TIA. 
 Every
amendment to or supplement of this Indenture, the Notes or the Note Guarantees shall comply with the TIA as then in effect, whether or not this Indenture is then qualified under the TIA. 
 Section 8.04. Revocation and Effect of Consents. 
 Until an amendment, waiver or supplement
becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not
made on any Note. Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Note or portion of such Note by notice to the Trustee or the Issuers received before the date on which the
Trustee receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. 
 The Partnership may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be
entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. 
 After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses
(1) through (10) of Section 8.02 hereof, in which case, the amendment, supplement or waiver shall bind only each Holder who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder’s Note; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of and interest on a Note, on or after the respective due dates expressed in such Note, or to
bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder. 
 Section 8.05. Notation on
or Exchange of Notes. 
 If an amendment, supplement or waiver changes the terms of a Note, the Trustee may request the Holder to deliver
it to the Trustee. In such case, the Trustee shall place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Issuers or the Trustee so determine, in exchange for the Note the Issuers shall
issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
  

 -75- 

 Section 8.06. Trustee To Sign Amendments, etc. 
 The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of any amendment,
supplement or waiver authorized pursuant to this Article 8 is authorized or permitted by this Indenture and that such amendment, supplement or waiver constitutes the legal, valid and binding obligation of the Issuers and any Guarantors, enforceable
in accordance with its terms (subject to customary exceptions). The Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture
or otherwise. 
 ARTICLE 9 
 DISCHARGE OF INDENTURE; DEFEASANCE 
 Section 9.01. Satisfaction and Discharge of Indenture. 
 (a) This Indenture shall be discharged and shall cease to be of further effect (except those obligations referred to in Section 9.01(c)) as to all
outstanding Notes and the Trustee, on written demand of and at the expense of the Issuers, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when: 
 (1) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and
Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuers and thereafter repaid to the Issuers or discharged from the trust of this Indenture) have been delivered to the Trustee for cancellation, or

 (2) (a) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable,
(ii) will become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption pursuant to paragraph 5 of the Notes and, in any case, the Issuers have irrevocably deposited or caused to be
deposited with the Trustee as trust funds, in trust solely for the benefit of the Holders, U.S. Dollars, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of
interest) to pay and discharge the entire Indebtedness (including all principal and accrued interest) on the Notes not theretofore delivered to the Trustee for cancellation, (b) the Issuers have paid all other sums payable by them under this
Indenture, and (c) the Issuers have delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at fixed maturity or on the Redemption Date, as the case may be. 
 (b) In addition, the Issuers must deliver an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent to satisfaction
and discharge have been complied with. 
 (c) Notwithstanding Section 9.01(a), the Issuers’ obligations in Article 2 and Sections
4.01, 4.07, 7.07, 9.06 and 9.07 hereof shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.08 hereof. After the Notes are no longer outstanding, the Issuers’ obligations in Sections 7.07,
9.06 and 9.07 hereof shall survive. 
  

 -76- 

 (d) After such delivery or irrevocable deposit, the Trustee upon request shall acknowledge in writing the
discharge of the Issuers’ and each Guarantor’s obligations under the Notes, the Note Guarantees and this Indenture except for those surviving obligations specified above. 
 (e) The Issuers shall provide notice of discharge or defeasance pursuant to this Article 9 within ten (10) days after deposit of funds or U.S.
Government Obligations. If payment at stated maturity of less than all of the Notes is to be provided for in the manner and with the effect provided in this Section 9.01, the Trustee shall select such Notes, or portions or principal amount
thereof, in the manner specified by Section 3.02 for selection for redemption of less than all the Notes. 
 Section 9.02. Legal Defeasance.

 (a) The Issuers may, at their option at any time, elect to have this Section be applied to all outstanding Notes upon compliance with the
conditions set forth in Section 9.04. 
 (b) Upon the Issuers exercise under paragraph (a) hereof of the option applicable to this
paragraph (b), the Issuers and each Guarantor shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from their respective obligations with respect to all outstanding Notes and
the Note Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers and each Guarantor shall be deemed to have paid and discharged
the entire Indebtedness represented by the outstanding Notes and the Note Guarantees, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 9.05 hereof and the other Sections of this Indenture referred
to in (i) and (ii) below, and to have satisfied all their other respective obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the
same), except for the following provisions, which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 9.05 hereof, and
as more fully set forth in such Section, payments in respect of the principal of and interest on such Notes when such payments are due from such trust fund, (ii) the Issuers’ obligations with respect to such Notes under Article 2 and
Section 4.07 hereof, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers’ obligations in connection therewith and (iv) this Article 9. Subject to compliance with this Article 9, the
Issuers may exercise its option under this Section 9.02 notwithstanding the prior exercise of its option under Section 9.03 below with respect to the Notes. 
 Section 9.03. Covenant Defeasance. 
 (a) The Issuers may, at their option, at any time, elect to
have this Section be applied to all outstanding Notes upon compliance with the conditions set forth in Section 9.04. 
 (b) Upon the
Partnership’s exercise under paragraph (a) hereof of the option applicable to this paragraph (b), the Issuers and each Guarantor shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be released from
their respective obligations under the covenants contained in Sections 4.02, 4.05 and 4.08 through 4.22 hereof, inclusive, and Section 5.01(a)(3) hereof with respect to the outstanding Notes and the Note Guarantees on and after the date the
conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”); provided, however, that Covenant Defeasance will also release all Note Guarantees as provided in Section 10.06(4) hereof but will not be
effective with respect to Events of Default contained in Sections 6.01(h) and (i) for 91 days after the deposit referred to in Section 9.04(1) hereof, and the Notes and the Note Guarantees shall thereafter be 

  

 -77- 

 
deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof)
in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes and the Note Guarantees, the
Issuers and each Guarantor may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event or Default under Section 6.01(c), (d), (e), or
(j) hereof, but, except as specified above, the remainder of this Indenture, and such Notes and the Note Guarantees shall be unaffected thereby. In addition, upon the Issuers’ exercise under paragraph (a) hereof of the option
applicable to this paragraph (b), subject to the satisfaction of the conditions set forth in Section 9.04 hereof, the Events of Default described under clauses (f) and (g) of Section 6.01 and the Events of Default described in
clauses (h) and (i) of Section 6.01 (but only with respect to Significant Subsidiaries of the Partnership), in each case, will no longer constitute an Event of Default. 
 Section 9.04. Conditions to Legal Defeasance or Covenant Defeasance. 
 The following shall be the
conditions to the application of either Section 9.02 or 9.03 hereof to the outstanding Notes and the Note Guarantees: 
 (1) the Issuers must irrevocably deposit with the Trustee (or other qualifying trustee), as trust funds, in trust solely for the benefit of the Holders, cash in U.S. Dollars or U.S. Government Obligations, or a combination thereof, in such
amounts as will be sufficient (without consideration of any reinvestment of interest), in the opinion of a nationally recognized investment bank, appraisal firm or firms of independent public accountants selected by the Issuers, to pay the principal
of and interest on the outstanding Notes on the scheduled due dates or on the applicable Redemption Date, as the case may be, provided that the Trustee shall have received an irrevocable written order from the Issuers instructing the Trustee
to apply such U.S. Dollars or the proceeds of such U.S. Government Obligations to said payments with respect to such Notes; 
 (2) in the case of an election under Section 9.02 hereof, the Issuers shall have delivered to the Trustee an Opinion of Counsel in the United States confirming that (A) the Issuers have received from, or there has been published
by, the Internal Revenue Service a ruling or (B) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm
that, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would
have been the case if the Legal Defeasance had not occurred; 
 (3) in the case of an election under Section 9.03 hereof,
the Issuers shall have delivered to the Trustee an Opinion of Counsel in the United States confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be
subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred; 
  

 -78- 

 (4) no Default shall have occurred and be continuing on the date of such deposit or
insofar as Sections 6.0 l(h) and 6.01(i) hereof are concerned, at any time in the period ending on the 91st day after the date of such deposit (other than a Default resulting from the incurrence of Indebtedness all or a portion of the proceeds of
which will be used to defease the Notes concurrently with such incurrence and the grant of any Lien securing such borrowings); 
 (5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of or constitute a default under this Indenture or any other material agreement or instrument to which the Partnership or any of its Subsidiaries is a
party or by which the Partnership or any of its Subsidiaries is bound (other than any such Default or default resulting solely from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings); 

(6) the Issuers shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers
with the intent of preferring the Holders over any other creditors of the Issuers or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuers or others; 
 (7) the Issuers shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that the
conditions precedent provided for in, in the case of the Officers’ Certificate, clauses (1) through (6) and, in the case of the Opinion of Counsel, clauses (2) and/or (3) and (5) of this Section 9.04 have been
complied with; 
 (8) the Issuers shall have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st
day following the deposit and assuming that no Holder is an “insider” with respect to the Issuers, as that term is defined in Section 101 of title 11, United States Bankruptcy Code (the “Bankruptcy Code”), the cash or
securities deposited in trust will not be subject to avoidance and repayment under Sections 547 and 550 of the Bankruptcy Code; 
 (9) such Legal Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest for purposes of the TIA with respect to any securities of the Issuers; and 
 (10) the Issuers shall have delivered to the Trustee an Opinion of Counsel stating that, as a result of such Legal Defeasance or Covenant
Defeasance, neither the trust nor the Trustee will be required to register as an investment company under the Investment Company Act of 1940, as amended. 
 Section 9.05. Application of Trust Money. 
 All money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee pursuant to Section 9.01 or 9.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either
directly or through any Paying Agent as the Trustee may determine, to the Holders of such Notes, of all sums due and to become due thereon in respect of principal, premium, if any, and accrued interest, but such money need not be segregated from
other funds except to the extent required by law. 
  

 -79- 

 The Issuers and the Guarantors shall pay and indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 9.01 or 9.04 hereof or the principal, premium, if any, and interest received in respect thereof other than any such tax, fee or other charge which by
law is for the account of the Holders. 
 Anything in this Article 9 to the contrary notwithstanding, the Trustee shall deliver or pay to the
Issuers from time to time upon a written request of the Issuers in the form of an Officers’ Certificate any money or U.S. Government Obligations held by it as provided in Section 9.01 or 9.04 hereof which, in the opinion of a
nationally-recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance. 
 Section 9.06. Repayment to the Issuers. 
 Subject to Sections 9.01, 9.02, 9.03, 9.04, 9.05 and 9.07 hereof, the Trustee and the Paying Agent shall promptly pay to the Issuers upon request any
excess U.S. Dollars or U.S. Government Obligations held by them at any time and thereupon shall be relieved from all liability with respect to such money or obligations. Subject to applicable abandoned property laws, the Trustee and the Paying Agent
shall pay to the Issuers upon request any money held by them for the payment of principal, premium, if any, or interest that remains unclaimed for two years; provided that the Trustee or such Paying Agent, before being required to make any
payment, may at the expense of the Issuers cause to be published once in a newspaper of general circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed, and that after a date
specified therein which shall be at least 30 days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Issuers. After payment to the Issuers, Holders entitled to such money must look
to the Issuers for payment as general creditors unless an applicable law designates another Person. 
 Section 9.07. Reinstatement. 

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 9.01 hereof by reason of any
legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers’ and each Guarantor’s obligations under this Indenture, the Notes
and the Note Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article 9 until such time as the Trustee or Paying Agent is permitted to apply all such U.S. legal tender or U.S. Government Obligations in
accordance with Section 9.01, 9.02 or 9.03 hereof; provided, however, that if the Issuers or the Guarantors have made any payment of principal of, premium, if any, or accrued interest on any Notes because of the reinstatement of their
obligations, the Issuers and each such Guarantor shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. 
  

 -80- 

 ARTICLE 10 
 GUARANTEES 
 Section 10.01. Unconditional Guarantee. 
 Each Guarantor hereby unconditionally, jointly and severally, guarantees to each Holder of a Note authenticated by the Trustee and to the Trustee and its
successors and assigns that the principal of, premium thereon (if any) and interest on the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at stated maturity, by acceleration or otherwise, and interest
on the overdue principal and interest on any overdue interest on the Notes and all other obligations of the Issuers to the Holders or the Trustee hereunder or under the Notes will be promptly paid in full or performed, all in accordance with the
terms hereof and thereof; subject, however, to the limitations set forth in Section 10.03 hereof. Each Guarantor hereby agrees that to the maximum extent permitted under applicable law, its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any
judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. To the maximum extent permitted under applicable law, each Guarantor
hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever
and covenants that the Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Issuers,
any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuers or any Guarantor, any amount paid by the Issuers or any Guarantor to the Trustee or such Holder, each Note Guarantee, to the extent
theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, to the maximum extent permitted under applicable law, as between a Guarantor, on the one hand, and the Holders and the Trustee, on the other
hand, (x) the maturity of the obligations Note Guaranteed hereby may be accelerated as provided in Article 6 hereof for the purpose of each Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration
in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) shall become due and payable by each Guarantor for
the purpose of each Note Guarantee. 
 Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’
fees) incurred by the Trustee or any Holder in enforcing any rights under this Article 10. 
 Section 10.02. Severability. 
 In case any provision of this Article 10 shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions
shall not in any way be affected or impaired thereby. 
  

 -81- 

 Section 10.03. Limitation on Guarantor’s Liability. 
 (a) To the extent applicable, a Guarantor’s liability in respect of its Note Guarantee shall be limited to the extent set forth below: 
 (1) Limitations Applicable to U.S. Guarantors. Each Guarantor that is incorporated, organized or formed, as the case may be, under
the laws of the United States, any State thereof or the District of Columbia (a “U.S. Guarantor”), and by its acceptance hereof, each Holder and the Trustee, hereby confirm that it is the intention of all such parties that the Note
Guarantee of a U.S. Guarantor does not constitute a fraudulent transfer or conveyance for purposes of Title 11 of the United States Code, as amended, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar U.S.
Federal or state or other applicable law. To effectuate the foregoing intention, each Holder and each U.S. Guarantor hereby irrevocably agree that the obligations of a U.S. Guarantor under its Note Guarantee shall be limited to the maximum amount as
will, after giving effect to all other contingent and fixed liabilities of such U.S. Guarantor (including, without limitation, any guarantees under the Credit Agreement) and after giving effect to any collections from or payments made by or on
behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such U.S. Guarantor not constituting such a
fraudulent transfer or conveyance. 
 (2) Limitations Applicable to Other Guarantors. Each Guarantor that is
incorporated, organized or formed, as the case may be, under the laws of any jurisdiction other than one set forth in clause (1) above (an “Other Guarantor”), and by its acceptance hereof, each Holder and the Trustee, hereby confirm
that it is the intention of all such parties that the Note Guarantee of an Other Guarantor does not constitute a fraudulent transfer or conveyance for purposes applicable law. To effectuate the foregoing intention, each Holder and each Other
Guarantor hereby irrevocably agree that the obligations of an Other Guarantor under its Note Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Other Guarantor
(including, without limitation, any guarantees under the Credit Agreement) and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note
Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Other Guarantor not constituting such a fraudulent transfer or conveyance. 
 (b) If following the date of this Indenture and notwithstanding anything in Section 8.02 to the contrary: 
 (1) (i) there shall be any change in the laws of the United States, any State thereof or the District of Columbia or (ii) any
Restricted Subsidiary incorporated, organized or formed, as the case may be, under the laws of any jurisdiction other than the United States, any State thereof or the District of Columbia (a “Future Guarantor”) shall be required to
execute a Note Guarantee and the Issuers shall reasonably determine that clause (2) with respect to Other Guarantors shall not adequately address the limitations on such Note Guarantee imposed by applicable law of the jurisdiction of
incorporation, organization or formation, as the case may be, of any such Future Guarantor; or 
 (2) the Issuers shall
reasonably determine that it shall be necessary or advisable to amend the terms of subsection (a) of this Section 10.03 or to add additional provisions related to the limitations imposed on the Note Guarantee of a Future Guarantor,

 then upon the delivery of an Officers’ Certificate and Opinion of Counsel reasonably satisfactory to the Trustee, the Issuers shall be entitled to
amend such clauses or add such additional provisions (including any related modifications to the form of notation of Note Guarantee attached hereto in Exhibit A), as the case may be, in order for the Note Guarantee of a Guarantor not to so
violate applicable law. 
  

 -82- 

 (c) Each Guarantor that makes a payment for distribution under its Note Guarantee shall be entitled to a
contribution from each other Guarantor in a pro rata amount based on adjusted net assets of each Guarantor. 
 Section 10.04. Successors and
Assigns. 
 This Article 10 shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the
successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture. 
 Section 10.05. No Waiver.

 Each of the Guarantors agrees that to the maximum extent permitted under applicable law, (a) neither a failure nor a delay on the part
of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or
privilege and (b) the rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in
equity, by statute or otherwise. 
 Section 10.06. Release of Guarantor. 
 A Guarantor shall be released from all of its obligations under its Note Guarantee and its obligations under this Indenture:

or otherwise, or a sale or other disposition of all of the Equity Interests of such Guarantor then held by the Partnership and its Restricted Subsidiaries; 
 (2) if such Guarantor is designated as an Unrestricted Subsidiary or otherwise ceases to be a Restricted Subsidiary, in each case in accordance with the provisions of this Indenture, upon effectiveness of such
designation or when it first ceases to be a Restricted Subsidiary, respectively; 
 (3) in the circumstances described in the
proviso of Section 4.20(a) hereof; or

 Section 10.07. Execution of Supplemental Indenture for Future Guarantors. 
 Each Subsidiary which is required to become a Guarantor shall, and the Issuers shall cause each such Subsidiary to, promptly execute and deliver to the
Trustee a supplemental indenture substantially in the form of Exhibit E hereto pursuant to which such Subsidiary shall become a Guarantor under this Article 10 and shall guarantee the obligations of the Issuers under the Notes and this
Indenture. Concurrently with the execution and delivery of such supplemental indenture, the Issuers shall deliver to the Trustee one or more Opinions of Counsel to the effect that such supplemental indenture has been duly authorized, executed and
delivered by such Subsidiary and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether
considered in a proceeding at law or in equity, the Note Guarantee of such Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms. 
 Section 10.08. Notation of Note Guarantee. 
 To
evidence the Note Guarantee set forth in this Article 10, each Guarantor hereby agrees that a notation of such Note Guarantee shall be placed on each Note authenticated and made available for delivery by the Trustee and that such notation of Note
Guarantee shall be executed on behalf of each Guarantor by the manual or facsimile signature of an Officer of each Guarantor. Each Guarantor hereby agrees that the Note Guarantee set forth in Section 10.01 hereof shall remain in full force and
effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. If an Officer of a Guarantor whose signature is on the notation of Note Guarantee no longer holds that office at the time the Trustee authenticates the
Note on which such notation of Note Guarantee is endorsed, the Note Guarantee shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantee set
forth in this Indenture on behalf of each Guarantor. 
 Section 10.09. Subordination of Subrogation and Other Rights. 
 Each Guarantor hereby agrees that any claim against the Issuers that arises from the payment, performance or enforcement of such Guarantor’s
obligations under the Note Guarantee or this Indenture, including, without limitation, any right of subrogation, shall be subject and subordinate to, and no payment with respect to any such claim of such Guarantor shall be made before, the payment
in full in cash of all outstanding Notes in accordance with the provisions provided therefor in this Indenture.

 1. Interest. Stallion Oilfield Services Ltd., a Texas limited partnership (the “Partnership”) and Stallion Oilfield Finance
Corp., a Texas corporation (“Finance Corp.” and, together with the Partnership, the “Issuers”), promise to pay interest on the principal amount of this Note at the rate per annum shown above. Interest on the
Notes will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from the date of the original issuance of the Notes. The Issuers will pay interest semi-annually in arrears on each Interest Payment Date,
commencing August 1, 2007. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 The Issuers shall pay
interest on overdue principal and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful from time to time on demand at the rate borne by the Notes. 
 2. Method of Payment. The Issuers shall pay interest on the Notes (except defaulted interest) to the Persons who are the registered Holders at the
close of business on the January 15 or July 15 immediately preceding the Interest Payment Date (whether or not such day is a Business Day) even if the Notes are cancelled on registration of transfer or registration of exchange after such
Record Date. Holders must surrender Notes to a Paying Agent to collect principal payments. If a Holder has given wire transfer instructions to the Partnership at least ten Business Days prior to the applicable payment date, the Issuers will make all
payments on such Holder’s Notes by wire transfer of immediately available funds to the account specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the Paying Agent or its affiliate within
the City and State of New York unless the Issuers elect to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders. 
 3. Paying Agent and Registrar. Initially, The Bank of New York Trust Company, N.A., a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Issuers may change any
Paying Agent, Registrar or co-Registrar without notice to the Holders. Neither the Partnership nor any of its Subsidiaries or Affiliates may act as Paying Agent but may act as Registrar or co-Registrar. 
 4. Indenture. The Issuers issued this Note under an Indenture, dated as of January 24, 2007 (the “Indenture”), by and among
the Issuers, the Guarantors and the Trustee. This Note is one of a duly authorized issue of Initial Notes of the Issuers designated as their 9 3/4% Senior Notes due 2015 (the “Notes”). The Notes include the Initial Notes and the
Additional Notes, if any. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders are referred to
the Indenture and the TIA for a statement of them. The Notes are general unsecured obligations of the Issuers.

(expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing on February 1 of the applicable year set forth below, plus, in each case, accrued unpaid interest thereon, if any, to the

 (b) Redemption at Applicable Premium. In addition, prior to February 1, 2011, the
Issuers may redeem the Notes, at their option, in whole at any time or in part from time to time, at a Redemption Price equal to 100% of the principal amount thereof, plus the Applicable Premium as of, and accrued and unpaid interest thereon, if
any, to the applicable Redemption Date (subject to the fight of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date). 
 (c) Redemption upon Consummation of Certain Qualified Equity Offerings. Notwithstanding the foregoing, at any time, or from time to time, prior to
February 1, 2010, the Issuers may on any one or more occasions, at their option, use all or any portion of the net cash proceeds of one or more Qualified Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes issued
at a Redemption Price equal to 109.750% of the principal amount thereof plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant
Interest Payment Date); provided that at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after giving effect to any such redemption. In order to effect the foregoing redemption
with the proceeds of any Qualified Equity Offering, the Issuers shall consummate such redemption not more than 90 days after the consummation of any such Qualified Equity Offering. 
 6. Notice of Redemption. Notice of redemption under paragraph 5 of this Note will be mailed at least 30 days but not more than 60 days before the
Redemption Date to each Holder to be redeemed at such Holder’s registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a satisfaction and discharge
of the Indenture. 
 Except as set forth in the Indenture, if monies for the redemption of the Notes called for redemption shall have been
deposited with the Paying Agent for redemption by 11:00 a.m., New York City time, on such Redemption Date, then, unless the Issuers default in the payment of such Redemption Price plus accrued interest, if any, the Notes called for redemption will
cease to bear interest from and after such Redemption Date and the only right of the Holders of such Notes will be to receive payment of the Redemption Price plus accrued interest, if any. 
 7. Offers to Purchase. The Indenture provides that, after certain Asset Sales and upon the occurrence of a Change of Control, and subject to
further limitations contained therein, the Partnership will make an offer to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture. 
  

 A-5 

 8. Denominations; Transfer; Exchange. The Notes are in registered form, without coupons, in
denominations of $2,000 and integral multiples $1,000 in excess thereof. A Holder shall register the transfer or exchange of Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to famish appropriate
endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer or exchange any Notes or portions
thereof selected for redemption. 
 9. Persons Deemed Owners. The registered Holder of a Note shall be treated as the owner of it for
all purposes. 
 10. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee
and the Paying Agent will pay the money back to the Issuers. After that, Holders entitled to money must look to the Issuers for payment as general creditors unless an “abandoned property” law designates another person. 
 11. Legal Defeasance and Covenant Defeasance. If the Issuers at any time deposit with the Trustee U.S. Dollars or U.S. Government Obligations
sufficient to pay the principal of and interest on the Notes to redemption or stated maturity and comply with the other provisions of the Indenture relating to defeasance, the Issuers will be discharged from certain provisions of the Indenture and
the Notes (including, in the case of Covenant Defeasance, certain covenants, but excluding its obligation to pay the principal of and interest on the Notes). 
 12. Amendments, Supplements, and Waivers. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate
principal amount of the Notes then outstanding, and any existing Default or Event of Default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in aggregate principal amount of the Notes then
outstanding. Without notice to or consent of any Holder, the Issuers and the Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes in addition
to or in place of certificated Notes or make any other change that does not adversely affect in any material respect the rights of any Holder. 
 13. Restrictive Covenants. The Indenture imposes certain limitations on the ability of each of the Partnership and its Restricted Subsidiaries to, among other things, incur additional Indebtedness, make payments in respect of its
Equity Interests, enter into transactions with Affiliates, enter into Sale and Leaseback Transactions, create dividend or other payment restrictions affecting Restricted Subsidiaries, sell assets, create liens, make certain Investments, merge or
consolidate with any other Person, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its assets. Such limitations are subject to a number of important qualifications and exceptions. The Issuers must
annually report to the Trustee on compliance with such limitations. 
 14. Successor Entity. When a successor entity assumes, in
accordance with the Indenture, all the obligations of its predecessor under the Notes and the Indenture, and immediately before and thereafter no Default exists and certain other conditions are satisfied, the predecessor entity will be released from
those obligations. 
 15. Defaults and Remedies. Events of Default are set forth in the Indenture. If an Event of Default (other than
an Event of Default specified in Section 6.01(h) or (i)) shall occur and be continuing, the Trustee, by written notice to the Partnership, or the Holders of at least 25% in aggregate 

  

 A-6 

 
principal amount of the Notes then outstanding by written notice to the Partnership and the Trustee, may declare all amounts owing under the Notes to be due
and payable; provided, however, that after such acceleration but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may, under certain circumstances, rescind and
annul such acceleration and its consequences if all existing Events of Default, other than the nonpayment of principal, premium or interest that has become due solely because of the acceleration, have been cured or waived. No such rescission shall
affect any subsequent Default or impair any right consequent thereto. In case an Event of Default specified in Section 6.01(h) or (i) of the Indenture occurs with respect to the Partnership and is continuing, such principal amount,
together with premium and interest with respect to all of the Notes, shall be due and payable immediately without any declaration or other act on the part of the Trustee or the Holders. 
 16. Trustee Dealings with the Issuers. The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Issuers, and may otherwise deal with the Issuers, their Subsidiaries or their respective Affiliates as if it were not the Trustee. 
 17. No Recourse Against Others. As more fully described in the Indenture, no director, officer, employee, incorporator, stockholder, member or
partner, as such, of the Issuers or any Guarantor shall have any liability for any obligation of the Issuers under the Notes or the Indenture or of any Guarantor under its Note Guarantee or for any claim based on, in respect of or by reason of such
obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes and the Note Guarantees. 
 18. Authentication. This Note shall not be valid until the Trustee or Authenticating Agent manually signs the certificate of authentication on
this Note. 
 19. Governing Law. THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK. 
 21. Abbreviations and Defined Terms. Customary abbreviations may be used in the name of a Holder or an
assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with fight of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

22. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuers have
caused CUSIP numbers to be printed on the Notes as a convenience to the Holders. No representation is made as to the accuracy of such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed hereon.

 23. Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the

 The undersigned represents and warrants to you that: 
 1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933 (the
“Securities Act”)) purchasing Notes for our own account or for the account of such an institutional “accredited investor” and we are acquiring the Notes not with a view to, or for offer or sale in connection with, any
distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risk of our investment in the Notes and we invest in or purchase securities
similar to the Notes in the normal course of our business. We and any accounts for which we are acting are each able to bear the economic risk of our or its investment. 
 2. We acknowledge that we have had access to such financial and other information, and have been afforded the opportunity to ask such questions of representatives of the Issuers and receive answers thereto, as we deem
necessary. 
 3. We understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold
except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Notes that we will not prior to the date (the “Resale Restriction Termination Date”) that is

required by any subsequent change in applicable law, offer, sell or otherwise transfer such Notes except (a) to the Issuers or any subsidiary of the Issuers, (b) inside the United States to a “qualified institutional buyer” in
compliance with Rule 144A under the Securities Act, (c) inside the United States to an “institutional accredited investor” as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act that, prior to such transfer,
furnishes (or has furnished on its behalf by a U.S. broker-dealer) to the Trustee a signed

Securities Act, (e) pursuant to any other available exemption from the registration requirements of the Securities Act or (f) pursuant to an effective registration statement under the Securities Act. We acknowledge that the Issuers and the
Trustee reserve the right prior to any offer, sale or other transfer prior to the Resale Restriction Termination Date of the applicable Notes pursuant to clause (c) or (e) above to require the delivery of an Opinion of Counsel,
certification and/or other information satisfactory to the Issuers and the Trustee. 
 We understand that the Trustee will not be required to
accept for registration of transfer any Notes acquired by us, except upon presentation of evidence satisfactory to the Issuers and the Trustee that the foregoing restrictions on transfer have been complied with. We further understand that any Notes
purchased by us will be in the form of definitive physical certificates and that such certificates will bear legend reflecting the substance of paragraph 3 of this letter. We further agree to provide to any person acquiring any of the Notes from us
a notice advising such person that transfers of such Notes are restricted as stated herein and that certificates representing such Notes will bear a legend to that effect. 
 We represent that the Issuers and the Trustee and others are entitled to rely upon the truth and accuracy of our acknowledgments, representations and
agreements set forth herein, and we agree to notify you promptly in writing if any of our acknowledgments, representations or agreements herein cease to be accurate and complete. You are also irrevocably authorized to produce this letter or a copy

 EXECUTION COPY 
 Exhibit 10.1 
 EMPLOYMENT AGREEMENT 
 AGREEMENT, dated as of May 30, 2007, by and between GENESEE & WYOMING INC., a Delaware corporation, whose principal place of
business is 66 Field Point Road, Greenwich, CT 06830 (the “Company”), and MORTIMER B. FULLER III (the “Executive”). 
 WHEREAS, the Executive is currently the Chief Executive Officer of the Company, and will remain in such position through May 30, 2007, after which he shall cease to provide services to the Company in that
capacity; 
 WHEREAS, the Company has determined to continue to employ the Executive, and the Executive has agreed to be so employed by the
Company, in accordance with the terms and provisions set forth herein; 
 NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS: 
 1. Employment and Duties. 
 (a)
General. During the Employment Period (as hereinafter defined), the Executive shall serve as Executive Chairman of the Company, reporting exclusively to the Board of Directors (the “Board”) of the Company. None of the
Company’s employees shall report to the Executive, save his executive assistant, except as otherwise determined by the Board from time to time. During the Employment Period, the Executive shall have all of the duties and responsibilities
commensurate with the Executive’s position as may be assigned to the Executive from time to time by the Board. The Executive’s place of employment shall be the principal offices of the Company in Greenwich, Connecticut, provided,
however, that the Executive understands and agrees that he may be required to travel from time to time for business reasons consistent with past practice. The Company agrees to use its best efforts to cause the Executive to be elected to the
Board, subject to nomination by the Board (in accordance with the recommendations of the Governance Committee of the Board) and to re-election by the shareholders of the Company. 
 (b) Exclusive Services. For so long as the Executive is employed by the Company, the Executive shall devote his full working time, which, with the
Board’s concurrence may be less than 40 hours per week but is expected to be a substantial commitment and may be project based, to his duties hereunder (provided that if the Executive’s employment is extended beyond the Initial
Employment Period (as hereinafter defined) the Company and the Executive may agree to a lesser time commitment), shall diligently and faithfully serve the Company, shall properly perform his duties and exercise his powers, comply with the Company
policies applicable to him from time to time regarding business conduct, conflicts of interest, confidentiality and otherwise, and shall use his best efforts to promote and serve the interests of the Company. Further, the Executive shall not,
directly or indirectly, render services for remuneration or otherwise to any other person or organization or otherwise engage in activities that would interfere with the faithful performance of his duties hereunder. Notwithstanding the foregoing,
the Executive may (i) serve on civic or charitable boards or engage in civic and charitable activities, (ii) serve on the boards of directors of any company to the extent permitted 

 
under guidelines developed by the Governance Committee of the Board, (iii) have other business interests (provided such interests do not conflict
in any way with the interests of the Company) and (iv) manage personal investments, in each case, as long as any such activity singularly or together with any other activity does not interfere with the Executive’s performance of his duties
and the meeting of his obligations hereunder. 
 2. Term of Employment. The Executive’s employment with the Company
pursuant to the terms of this Agreement shall commence on June 1, 2007 (the “Effective Date”), and shall continue until December 31, 2009 (the “Initial Employment Period”), unless renewed prior to such
December 31 (or any subsequent December 31, as the case may be) by the mutual agreement of the Executive and the Company for an additional period of one calendar year (with each such additional period, a “Renewal Employment
Period”) or terminated earlier than the scheduled end of the Initial Employment Period or any Renewal Employment Period in accordance with Section 4 of this Agreement. The period from the Effective Date until the termination of the
Executive’s employment hereunder in accordance with the terms of this Agreement is hereinafter referred to as the “Employment Period.”  
 3. Compensation and Other Benefits. Subject to the provisions of this Agreement, the Company shall pay and provide the following compensation and other benefits to the Executive during the Employment Period as
compensation for services rendered: 
 (a) Base Salary. The Company shall pay to the Executive an annual salary (the “Base
Salary”) at the rate of $665,000 for calendar year 2007, which rate shall be retroactive to January 1, 2007, and subject to appropriate adjustment in accordance with the cost-of-living policies generally applicable to all employees of
the Company for calendar years 2008 and 2009, payable in substantially equal installments in accordance with the ordinary payroll practices of the Company as established from time to time. In the event that the Executive’s employment hereunder
should continue after December 31, 2009, the Base Salary shall be appropriately adjusted pursuant to negotiation to reflect the scope of the Executive’s authority, duties and expected time commitment with respect to periods of employment
after calendar year 2009. 
 (b) Annual Bonus. In addition to the amounts to be paid to the Executive pursuant to Sections 3(a) and
(c), the Executive shall be eligible to earn an annual cash bonus (the “Annual Bonus”) in accordance with and the subject to the terms of the Genesee Value Added methodology under the Omnibus Plan (as defined below) or such
successor incentive plan or program as may be in effect from time to time and applicable to other senior executive officers of the Company (the “GVA Plan”). Payment of the Annual Bonus shall be based upon the successful achievement
of one or more annual performance objectives applicable to such senior executive officers generally. The target amount of the Annual Bonus for the Executive for calendar year 2007 shall be 60% of the Base Salary in effect for such calendar year; for
each calendar year following 2007 during the Initial Employment Period the target Annual Bonus shall be 50% of the amount of the Base Salary in effect for each such calendar year. In the event that the Executive’s employment hereunder should
continue after December 31, 2009, the target amount of the Annual Bonus shall be appropriately adjusted pursuant to negotiation to reflect the scope of the Executive’s authority, duties and expected time commitment. 
  

 2 

 (c) Equity Awards and Stock Options. In addition to the amounts to be paid to the Executive
pursuant to Sections 3(a) and (b), the Executive shall continue to be eligible to receive discretionary annual grants of equity incentive awards on the same basis as such grants are made to other senior executive officers of the Company (the
“Annual Equity Grants”) in accordance with and subject to the terms of the Company’s 2004 Omnibus Incentive Plan or such successor incentive plan as may be in effect from time to time and applicable to other senior executive
officers (the “Omnibus Plan”) and the terms of any award agreement issued thereunder; provided, however, for grants made in respect of any Renewal Employment Period, such basis for granting awards shall be subject to
appropriate adjustment to reflect any changes to the scope of the Executive’s authority, duties and expected time commitment for such periods. 
 (d) Pension Benefit Plans. The Executive shall be eligible to participate in the Company 401(k) plan and any other defined contribution or defined benefit retirement plan, or any successor thereto, maintained or contributed to by the
Company, or any subsidiary thereof, and providing pension benefits, including, without limitation, any such plan established for the purpose of providing such benefits for employees of the railroad industry, in accordance with and subject to the
terms of such plans, as they may be amended from time to time. 
 (e) Welfare Benefit Plans. The Executive and/or his eligible
dependents shall be eligible to participate in the Company’s welfare benefit plans and programs generally applicable to other senior executive officers of the Company, in accordance with and subject to the terms of the plans, as they may be
amended from time to time. 
 (f) Deferred Compensation Plan. During the Employment Period, the Executive shall be eligible to
continue to participate in the Company’s Deferred Compensation Plan or any similar or successor deferred compensation plan, program or arrangement, if any, maintained by the Company and generally applicable to other senior executive officers of
the Company, in accordance with and subject to the terms of the plans, as they may be amended from time to time. 
 (g) Life
Insurance. Unless the Executive dies, is disabled (as defined in Section 4(d) hereof), is terminated for Cause or resigns without Good Reason prior to the end of the period specified below, the Company shall continue to pay the Executive an
amount equal to the sum of (i) the annual premium payable on the life insurance policies currently maintained by the Company for the Executive plus (ii) a tax gross-up payment in an amount equal to any taxes that are due on
account of such premium payments, with the sum of such amounts to be payable each year, at the same time such payments are made for any other senior executives for whom such insurance is maintained by the Company. Such payments shall continue to be
made for the period beginning with calendar year 2007 through and including the calendar year in which the Executive attains age 70. The foregoing notwithstanding, at Company’s option after consultation with the Executive, the Company, in lieu
of such program, may provide a program with substantially the same economic benefits. 
 (h) Business and Travel Expenses. The Company
shall reimburse the Executive for reasonable business travel expenses and other business-related expenses properly incurred by the Executive in the fulfillment of his duties hereunder upon presentation of written documentation thereof, in accordance
with and subject to the applicable expense reimbursement 

  

 3 

 
policies and procedures of the Company as in effect from time to time; provided, however, that such expenses reported in such written
documentation shall be reviewed by the Compensation Committee of the Board on a quarterly basis, and shall be subject to the approval of such Compensation Committee. 
 (i) Matching Program for Charitable Gifts. The Executive shall be eligible to participate in the Company’s program for matching charitable contributions by employees. Subject to the limits under such
program, the Company will match all such charitable gifts by the Executive for any calendar at a rate or amount no lower than the rate or amount applicable to the chief executive officer of the Company or to members of the Board for such year,
whichever is higher. 
 (j) Vacation. The Executive shall be entitled to receive vacation and paid-off time as may be available
generally to other senior executive officers of the Company, subject to the terms of any applicable plan or policy and to proration in the event the Executive’s employment terminates other than at calendar year end. 
 (k) Physical Exams for Executives. The Executive will be eligible to participate in the Company’s annual physical examination program for its
executive officers on the same basis as the other executive officers. To the extent permitted under such plan, the Executive shall be entitled to select the physician who will conduct the examination. 
 (l) Office Support and Staff. During the Employment Period, the Company shall provide the Executive with an office, office furnishings and
secretarial and other administrative support in a manner commensurate with his status. Such office and support shall be at the Company’s principal offices and the assistant shall be assigned to Executive on a dedicated basis, but the assistant
may have other duties also. Initially, such assistant shall be the Executive’s current assistant; in the event of her departure, the Company shall assign to the Executive another assistant subject to the Executive’s consent, which shall
not be unreasonably withheld or delayed. 
 (m) Indemnification. During the Employment Period the Company will not take any action
that would lessen Executive’s eligibility for indemnification under applicable law, Company organizational documents, contracts, and insurance, compared with the eligibility of other senior executive officers in effect from time to time. The
Executive’s post-termination rights to indemnification also shall be no less favorable than those applicable from time to time to other former officers and directors of the Company. 
 (n) Perquisites. During the Employment Period, the Executive shall be entitled to perquisites and executive benefits consistent with those made
available to other senior executive officers of the Company from time to time. 
 4. Termination of Employment during the Employment
Period. 
 (a) Termination of Employment in General; Notice. Subject to the further provisions of this Section 4, during the
Initial Employment Period or any subsequent Renewal Employment Period the Company may terminate the Executive’s employment, and the Executive may resign his employment with the Company, at any time for any reason or for no stated 

  

 4 

 
reason. In no event shall the failure or unwillingness of the Company to agree to a renewal of the Executive’s employment pursuant to the terms of this
Agreement in accordance with the terms of Section 2 hereof constitute a termination by the Company of the Executive’s employment hereunder for purposes of this Section 4, and any rights to any payments or benefits the Executive may
have following such expiration of the Initial Employment Period or any subsequent Renewal Employment Period shall not arise under or be governed by the terms of this Agreement. During the Employment Period, the following amounts shall be paid or
provided to the Executive (or in the event of the Executive’s death, to his estate or beneficiary) if his employment with Company ends for any reason (collectively, the “Accrued Amounts”): (i) payment of any unpaid Base
Salary for the period of the Employment Period through and including the applicable date of termination or resignation; (ii) the amount of any Annual Bonus accrued but unpaid with respect to any completed fiscal year of the Company as of the
date such termination or resignation occurs; (iii) a cash payment for the amount of any earned but unused vacation time in accordance with Company policies; (iv) a cash payment for all properly incurred but unreimbursed amounts for
reasonable business travel and other business-related expenses in accordance with the terms of Section 3(h) hereof; and (v) any other amounts or benefits required to be paid or provided by law or under the terms of any applicable pension,
welfare or equity compensation plan of the Company. The Accrued Amounts shall be paid to the Executive at the applicable time or times otherwise contemplated by Section 3 of this Agreement or, if no time is contemplated by Section 3,
within 30 days following the date of such termination or resignation. 
 (b) Termination for Cause; Resignation Without Good Reason.
During the Initial Employment Period or any subsequent Renewal Employment Period, the Company may terminate the Executive’s employment immediately for Cause (as hereinafter defined), and the Executive may resign his employment with the Company
without Good Reason (as hereinafter defined), in either of which event the Executive shall be entitled to the Accrued Amounts. The Executive shall have no further right to receive any other compensation or benefits after such termination or
resignation of employment. 
 (c) Termination Without Cause; Resignation for Good Reason. During the Initial Employment Period or any
subsequent Renewal Employment Period, the Company shall give the Executive not less than 30 days prior written notice of its intention to terminate his employment without Cause, and the Executive shall give the Company not less than 30 days’
prior written notice of his intention to resign his employment for Good Reason. If, during the Initial Employment Period or any subsequent Renewal Employment Period, the Executive’s employment is terminated by the Company without Cause or if
the Executive resigns from his employment for Good Reason, in lieu of all other amounts that otherwise may be due to the Executive in such events, the Company shall pay the Executive the Accrued Amounts. In addition, subject to the Executive’s
execution and delivery of a general release of claims in the form attached hereto as Exhibit A, the Executive shall be entitled to (i) a cash lump sum payment in an amount equal to three hundred percent (300%) of the Base Salary in effect
on the date of such termination or resignation; (ii) full vesting of all stock options, restricted stock awards and other equity awards outstanding as of the date of such termination or resignation to the extent provided for under existing
plans and award agreements, provided, however, that any unvested restricted stock awards granted on June 2, 2006 as bonuses to the Executive in connection with the 2006 sale and disposition of the operations and other assets of
the Australian Railroad Group Pty. Ltd. to Queensland Rail and Babcock & Brown Limited and related transactions shall fully 

  

 5 

 
vest notwithstanding any contrary provisions in the applicable plan or award agreement; (iii) payment by the Company of all annual premiums (and related
tax gross-up payments) for the Executive’s life insurance coverage (as described in Section 4(g)) due for the period beginning with the year that includes the date of such termination or resignation through and including the year in which
the Executive attains age 70; and (iv) payment by the Company of all premiums payable with respect to the Medicare supplemental insurance for the Executive and his dependents for the period beginning on the date of such termination or
resignation and ending on the third anniversary thereof (all such payments and benefits together, the “Severance Obligations”). The Company shall pay the cash payment portion the Severance Obligations to the Executive no later than
30 days following the date of the Executive’s termination or resignation of employment, and shall pay the insurance premium payment portion of the Severance Obligations in accordance with the Company’s ordinary practice with respect to
such payments. The Executive shall not be obligated to seek other employment or take any other employment or take any other action by way of mitigation of the amounts payable to the Executive under this Section 4(c), and the amounts payable
hereunder shall not be reduced or offset by any amounts that the Executive earns after his termination or resignation of employment with the Company. Subject to any applicable law or regulatory requirement, the Executive and the Company hereby
mutually agree to cooperate in drafting any public communication regarding a termination or resignation described in this Section 3(d); the text of which communication shall be subject to their mutual agreement prior to its publication.

 (d) Termination Due to Death or Disability. During the Initial Employment Period or any subsequent Renewal Employment Period, the
Executive’s employment with the Company shall terminate automatically on the date of the Executive’s death. In the event of the Executive’s Disability (as defined under the Company’s long-term disability plan generally applicable
to senior executive officers of the Company) during the Initial Employment Period or any subsequent Renewal Employment Period, the Company shall be entitled to terminate his employment. In the event of termination of the Executive’s employment
by reason of the Executive’s death or Disability, the Company shall pay to the Executive (or his estate, as applicable), the Accrued Amounts and the benefits due under the Company’s life insurance and long-term disability plans in which
the Executive participates at the time of such termination; in addition, all stock options, restricted stock awards and other equity awards outstanding as of the date of such termination or resignation shall fully vest, to the extent provided for
under the terms of the applicable equity incentive plan or award agreement. 
 (e) Termination following a Change of Control. If, at
any time during the Initial Employment Period or any subsequent Renewal Employment Period, the Executive is entitled to any payment or benefits under the terms of that certain agreement between the Company and the Executive, dated June 24,
1996, relating to change-of-control severance, as such agreement may be amended or superseded from time to time (the “Change of Control Agreement”), the terms of Section 4(c) hereof shall not apply and in its place the Change
of Control Agreement shall govern and any severance payment or provision of benefits to the Executive shall be made solely in accordance with the terms thereof. Notwithstanding the terms of this Agreement, or anything to the contrary in the Change
of Control Agreement, the Executive hereby acknowledges and agrees that for any period following the expiration of the Initial Employment Period or any subsequent Renewal Employment Period in accordance with Section 2 hereof the Change of
Control Agreement shall not apply to the Executive and shall be 

  

 6 

 
of no force or effect for such period, including (for the avoidance of doubt) any period during which the Executive provides services to the Company as a
consultant, employee or any other capacity, during the Transitional Period or thereafter. 
 (f) Notice of Termination. Any
termination of employment by the Company or the Executive shall be communicated by a written “Notice of Termination” to the other party hereto given in accordance with Section 16 of this Agreement. In the event of a termination
by the Company for Cause, or by the Executive for Good Reason, the Notice of Termination shall (i) indicate the specific termination provision in this Agreement relied upon, (ii) set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive’s employment under the provision so indicated and (iii) specify the date of termination. The failure by the Executive or the Company to set forth in the Notice of Termination any
fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company, respectively, hereunder or preclude the Executive or the Company, respectively, from asserting such fact or
circumstance in enforcing the Executive’s or the Company’s rights hereunder. 
 (g) “Cause” means the
Executive’s (i) willful and continued failure to perform substantially all of his duties with the Company (other than any such failure resulting from incapacity due to physical or mental illness) for a period of 10 days following the
delivery of a written demand for substantial performance to the Executive by the Board, which specifically identifies the manner in which the Board believes the Executive has not substantially performed his duties; (ii) intentional dishonesty
on the part of the Executive in the performance of his duties with the Company; (iii) conviction of, or entry of a plea of guilty or nolo contendere to charges of, any crime under the laws of the United States or any state thereof, or
any other jurisdiction in which the Company conducts business or provides services, which constitutes (x) a felony or (y) a misdemeanor involving moral turpitude; (iv) willful malfeasance or willful misconduct in
connection with the Executive’s duties with the Company or any act or omission which is injurious to the financial condition or business reputation of the Company or its Affiliates; (v) material breach of this Agreement or any other
agreement between Executive and the Company; or (vi) other conduct that reasonably could be anticipated to be materially harmful to the business, interests, or reputation of the Company, each as determined by the Board in its reasonable
judgment. 
 (h) “Good Reason” shall mean (i) a material breach by the Company of the terms of this Agreement;
(ii) a material reduction by the Company in the Executive’s annual base salary or annual cash bonus target compensation in violation of this Agreement; (iii) a failure by the Company to provide the office and support referenced in
Section 3(l) hereof in a location within is more than 50 miles commuting distance (one way) from the Executive’s current residence in Rye, New York; or (iv) requiring the Executive to be on travel status to an extent materially
greater (measured over a period of at least six months) than the Executive was prior to the Effective Date; provided, however, that no event or condition shall constitute Good Reason unless (A) the Executive gives the Company,
written notice of his intention to terminate his employment for Good Reason and the grounds for such termination no later than sixty (60) days of the occurrence of the act or omission that the Executive believes constitutes such grounds and
(B) such grounds for termination (if susceptible to correction) are not corrected by the Company within 30 days of its receipt of such notice. 
  

 7 

 5. Confidentiality. 
 (a) Confidential Information. Without limiting the Executive’s duties under the law, and in addition thereto, the Executive shall not, during the Employment Period or thereafter (unless in the course of
the Executive’s employment and necessary for the performance of the Executive’s duties, or unless with the written consent of the Company), directly or indirectly divulge, disclose, or communicate to any person, firm or corporation in any
manner whatsoever any information of any kind, nature, or description concerning any matter affecting or relating to the business of the Company or its subsidiaries (the “Company Group”), or any matter affecting or relating to its
customers, including, without limitation, any trade secrets or any correspondence, accounts, connections or dealings of the Company Group or any knowledge gained in relation thereto during the Executive’s employment and any information
whatsoever concerning any past or present customer of the Company Group (“Confidential Information”); provided, however, that the restrictions contained in this Section 5(a) shall not apply to any information that
has entered into the public domain other than by reason of the Executive’s breach. 
 (b) In the event that the Executive becomes
legally compelled to disclose any Confidential Information, the Executive shall provide the Company with prompt written notice so that the Company may seek a protective order or other appropriate remedy. In the event that such protective order or
other remedy is not obtained, the Executive shall furnish only that portion of such Confidential Information or take only such action as is legally required by binding order and shall exercise his reasonable efforts to obtain reliable assurance that
confidential treatment shall be accorded any such Confidential Information. 
 (c) Exclusive Property. The Executive confirms that all
Confidential Information is and shall remain the exclusive property of the Company Group. All business records, papers and documents kept or made by the Executive relating to the business of the Company or the Company Group shall be and remain the
property of the Company or the Company Group. 
 6. Noncompetition and Nonsolicitation. 
 (a) The Executive agrees that during the Employment Period and any period subsequent to the Employment Period during which he provides any consulting
services to the Company in accordance with the terms of Section 7 hereof, and for a period beginning on the later of the date his employment hereunder terminates or the last day of the Transitional Period (as defined in Section 7 hereof)
(either date, the “Termination Date”) and ending on the second anniversary thereof (the “Restricted Period”), the Executive shall not, without the prior written consent of the Company, either alone or in concert or
association with others, directly or indirectly, for remuneration or otherwise, either as principal, agent, consultant, employee, stockholder (other than as a passive investor in 2% or less of the equity securities of a publicly traded entity) or
any other capacity, perform any services or engage in any work for or on behalf of any company, firm, partnership, joint venture or other business enterprise or business entity that competes with any business or activity of the Company Group.

  

 8 

 (b) The Executive agrees that during the Restricted Period, the Executive shall not directly or
indirectly (i) solicit, induce or attempt to solicit or induce any person who is, or during the then most recent 12-month period was, an employee or officer of the Company Group, and who the Executive knows or reasonably should know is or was
such a person, to leave the employ of the Company Group or violate the terms of his or her contract, or any employment arrangement, with the Company Group; or (ii) induce or attempt to induce any customer, client, supplier, licensee or other
business relation of the Company Group that the Executive knows or reasonably should know is such a person or entity to cease doing business with the Company Group. As used herein the term “indirectly” shall (x) include, without
limitation, the Executive’s permitting the use of the Executive’s name by any competitor of the Company Group in violation of this Section 6(b) and (y) not include any general, non-targeted employment advertising efforts by any
person employing or otherwise affiliated with the Executive. 
 7. Transitional Services. 
 (a) For the period beginning on the last day of the Employment Period (other than where the Employment Period ends early in accordance with the terms of
Section 4 hereof) and ending on the December 31 of the year in which the Executive attains age 75 (the “Transitional Period”), the Executive hereby agrees to perform consulting services as an independent contractor to the
Company, and the Company hereby agrees to accept and pay for such services for the Transitional Period at a rate of $10,000 per month. Executive shall also be entitled to any amounts due under Section 3(g) above during such Transitional Period.
During the Transitional Period, the Company further hereby agrees to provide the Executive at its own expense with office space at the Company’s principal offices and with a dedicated assistant (who may have other duties in addition to his or
her duties to the Executive). Such office shall be at the Company’s principal offices. The Executive hereby agrees to provide an annual average of at least 20 hours of service per month. Subject to recommendation of the Governance Committee,
nomination by the Board and election by the shareholders, and any applicable Board policy, the Company acknowledges and agrees that it is expected that the Executive will remain a member of the Board until he attains age 75, and after age 75 may
remain such a member until such time as shall be determined by the Board, subject to the above-mentioned nomination and election factors. During the Transitional Period and to the extent the Executive is a non-employee director of the Company, the
Executive will receive the standard fees payable to non-employee directors of the Company and will remain eligible to receive equity incentive grants received at the same time and on the same terms as applicable other non-employee directors of the
Company from time to time. 
 (b) Notwithstanding anything to the contrary in Section 7(a) hereof, the Executive may elect, with the
approval of the Chief Executive Officer of the Company, to continue to provide services during the Transitional Period as an employee of the Company rather than as an independent contractor until the earlier of the Executive’s resignation from
the Company or the end of the calendar year in which the Executive attains age 72. If the Executive continues to provide services to the Company thereafter, he shall do so solely as an independent contractor for the balance of the Transitional
Period. The Executive hereby acknowledges and agrees that if he so elects to provide services as an employee of the Company during the Transitional Period he shall not be entitled during such period to participate in, and his service 

  

 9 

 
during such period shall not count for eligibility, vesting or benefit accrual purposes under any pension, welfare, equity or cash incentive, deferred
compensation or any other employee benefit plan or arrangement of the Company, or any fringe benefit or employee services plan, program, policy or practice of the Company, and that he shall provide such services solely on an at-will basis, subject
to termination by the Company at any time for any reason or no stated reason with no right to any payment or benefit as a result of or in connection with such termination, provided, however, that the Executive will be entitled to any
amounts due under Section 3(g) above. In no event will any employment under this Section 7 be considered part of the Employment Period, nor will the Change of Control Agreement have any force or effect during the period of employment under
this Section 7. 
 8. Source of Payments. All payments provided under this Agreement, other than payments made pursuant to a plan
which provides otherwise, shall be paid in cash from the general funds of the Company, and no special or separate fund shall be established, and no other segregation of assets shall be made, to assure payment. The Executive shall have no right,
title or interest whatsoever in or to any investments which the Company may make to aid the Company in meeting its obligations hereunder. 
 9. Nonassignability; Binding Agreement. 
 (a) By the Executive. Neither this Agreement nor any or all rights, duties,
obligations or interests hereunder shall be assignable or delegable by the Executive. 
 (b) By the Company. This Agreement and all of
the Company’s rights and obligations hereunder shall not be assignable by the Company except as incident to a reorganization, merger or consolidation, or transfer of all or substantially all of the Company’s assets, but no such assignment
by the Company shall relieve the Company of its obligations hereunder without the Executive’s consent. 
 (c) Binding Effect.
This Agreement shall not be binding upon, nor inure to the benefit of, the parties hereto, any successors to or assigns of the Company, except in accordance with the terms of Section 9(b) hereof, or to the Executive’s heirs or the personal
representatives of his estate, except as a result of the Executive’s death or disability. 
 10. Withholding. Any payments made
or benefits provided to the Executive under this Agreement shall be reduced by any applicable withholding taxes or other amounts required to be withheld by law. 
 11. Amendment; Waiver. This Agreement may not be modified, amended or waived in any manner, except by an instrument in writing signed by both parties hereto. The waiver by either party of compliance with any
provision of this Agreement by the other party shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by such party of a provision of this Agreement. 
 12. Governing Law. All matters affecting this Agreement, including the validity thereof, are to be governed by, and interpreted and construed in
accordance with, the laws of the State of New York, except as superseded by applicable federal law, without giving effect to its conflicts of law provisions. 
  

 10 

 13. Entire Agreement; Supersedes Previous Agreements. This Agreement contains the entire agreement
and understanding of the parties hereto with respect to the matters covered herein and supersedes all prior or contemporaneous negotiations, commitments, agreements and writings with respect to the subject matter hereof, all such other negotiations,
commitments, agreements and writings shall have no further force or effect, and the parties to any such other negotiation, commitment, agreement or writing shall have no further rights or obligations thereunder. Notwithstanding the foregoing, the
Change of Control Agreement and any equity award agreement outstanding as of the Effective Date (and any equity incentive plan pursuant to which such awards were granted) shall remain in full force and effect in accordance with their terms,
provided, however, that the June 2, 2006 equity awards shall be modified in accordance with Section 4(c) hereof. The Executive acknowledges that he has not been induced to enter into this Agreement by any representation, warranty or
undertaking not expressly incorporated into it. The Executive agrees and acknowledges that his only rights and remedies in relation to any representation, warranty or undertaking made or given in connection with this Agreement (unless such
representation, warranty or undertaking was made fraudulently) will be for breach of the terms of this Agreement, to the exclusion of all other rights and remedies (including those in tort or arising under statute).

 This Waiver and General Release of All Claims Agreement (this

The Executive has been employed by the Company pursuant to the Employment Agreement, dated May 30, 2007, between the Company and the Executive
(the “Employment Agreement”). Any term not defined herein shall have the same meaning as under the Employment Agreement. In consideration for the payments and benefits set forth in Section 4(c) of the Employment Agreement, the

successors, subsidiaries, affiliates and divisions (the “Company Group”) and all of their current and former trustees, officers, directors, partners, shareholders, employees, consultants, independent contractors, agents, assigns and
representatives, including without limitation all persons acting by, through, under or in concert with any of them (together with the Company Group, individually and collectively, the “Company Group Releasees”), from any and all
charges, complaints, claims, controversies, liabilities, demands, promises, actions, causes of action, suits, rights, grievances, proceedings, costs, expenses, damages, debts, taxes, allowances, and remedies (including attorneys’ fees and
costs) of any nature whatsoever, known or unknown, whether in law or equity (individually and collectively, “Claims”), including, but not limited to, those Claims arising out of the Executive’s employment or termination of
employment with the Company, which the Executive may have by reason of any matter, cause, act, or omission. 
 (ii) This Release includes a
release of all rights and Claims under, as amended, Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment Act of 1967, the Rehabilitation Act of 1973, the Civil Rights Act of 1866 and 1991, the Americans with Disabilities

citizenship, veteran status, disability, and other legally protected categories. 
 (iii) Notwithstanding anything herein to the contrary,
the sole matters to which the Release does not apply are: (i) the Executive’s rights under this Release and the Employment Agreement to the extent that such rights are intended thereunder to survive the termination of employment and
(ii) the Executive’s rights under any tax-qualified pension or claims for accrued or vested benefits under any other any applicable welfare, equity compensation or other benefit plan maintained by the Company or under COBRA. 
  

 14 

 (b) No Claims. The Executive agrees that prior to the date hereof, he has not instituted, assisted
or otherwise participated in connection with, any action, complaint, claim, charge, grievance, arbitration, lawsuit, or administrative agency proceeding, or action at law or otherwise against the Company Group Releasees or any member thereof, and
for himself and all the Releasors waives the right to pursue individually or collectively any Claims against any Company Group Releasees under any applicable dispute resolution procedure, including any arbitration policy. 
 (c) Specific Release of ADEA Claims. In further consideration of the payments and benefits provided to the Executive, including, without
limitation, the Executive’s obligations under the Employment Agreement, the Executive hereby unconditionally releases and forever discharges the Company Group Releasees from any and all Claims that the Releasors may have as of the date the

(i) this entire Release is written in a manner calculated to be understood by him; (ii) he has been advised to consult with an attorney before executing this Release; (iii) he was given a period of twenty-one days within which to

benefits under Section 4(c) of the Employment Agreement shall not become effective, and no payments or benefits shall be made or provided thereunder, until the day after the expiration of such seven-day period (the “Revocation
Date”). Upon such revocation, this Release and the afore-mentioned severance provisions of the Employment Agreement shall be null and void and of no further force or effect. 
 (d) No Assignment. The Executive represents and warrants that he has not assigned any of the Claims being released under this Agreement.

 (e) Governing Law. All matters affecting this Release, including the validity thereof, will be governed by, and construed in
accordance with, the laws of the State of New York. 
 (f) Enforceability. In the event that any provision of this Release should be
held to be invalid or unenforceable, each and all of the other provisions of this Release shall remain in full force and effect. If any provision of this Release is found to be invalid or unenforceable, such provision shall be modified as necessary
to permit this Release to be upheld and enforced to the maximum extent permitted by law. 
 (g) Entire Agreement. This Release sets
forth the complete understanding between the Executive and the Company in respect of the subject matter of this Release and supersedes all prior agreements relating to the same subject matter. The Executive has not relied upon any representations,
promises or agreements of any kind except those set forth herein in signing this Release. 
  

 15 

 (h) Amendment. This Release may not be amended except by a written agreement signed by both
parties which specifically refers to this Release.
