Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 3.06 hereof.

Section 3.02 Execution and Authentication.

At least one Officer must sign the Notes for the Issuer by manual, facsimile or electronically transmitted signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under the Indenture.

The Trustee will, upon receipt of a written order of the Issuer signed by an Officer of the Issuer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under the Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuer pursuant to one or more Authentication Orders, except as provided in Section 3.07 hereof.

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in the Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Issuer.

Section 3.03 Registrar and Paying Agent.

The Issuer will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee in writing of the name and address of any Agent not a party to the Indenture. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

The Issuer initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

The Issuer initially appoints the Trustee to act as the Registrar and Paying Agent (at its office in Houston, Texas indicated in the definition of Corporate Trust Office of the Trustee in Section 2.01 hereof) and to act as Custodian with respect to the Global Notes.

Section 3.04 Paying Agent to Hold Money in Trust.

The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or premium or interest, if any, on, the Notes, and will notify

the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary of the Issuer) will have no further liability for the money. If the Issuer or a Subsidiary of the Issuer acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will serve as Paying Agent for the Notes.

Section 3.05 Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA §312(a). If the Trustee is not the Registrar, the Issuer will furnish to the Trustee at least seven Business Days before each interest payment date 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 the Holders of the Notes and the Issuer shall otherwise comply with TIA §312(a).

Section 3.06 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All beneficial interests in the Global Notes will be exchanged by the Issuer for Definitive Notes if:

(1) the Issuer delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 90 days after the date of such notice from the Depositary;

(2) the Issuer, at its option but subject to DTC’s requirements, determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and deliver a written notice to such effect to the Trustee; or

(3) there has occurred and is continuing an Event of Default with respect to the Notes, and the Depositary notifies the Trustee of its decision to exchange the Global Notes for Definitive Notes.

Upon the occurrence of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 3.07 and 3.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 3.06 or Section 3.07 or Section 3.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for

another Note other than as provided in this Section 3.06(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 3.06(b) hereof.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of the Indenture and the Applicable Procedures.

(1) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 3.06(b)(1).

(2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 3.06(b)(1), the transferor of such beneficial interest must deliver to the Registrar either:

(A) both:

(i) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and

(ii) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase; or

(B) both:

(i) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged; and

(ii) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect such transfer or exchange referred to in clause (1) above.

(c) Transfer and Exchange of Beneficial Interests in Global Notes to Definitive Notes. If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery

thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 3.06(b)(2) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 3.06(g) hereof, and the Issuer will execute and the Trustee will authenticate and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 3.06(c) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the Persons in whose names such Notes are so registered.

(d) Transfer and Exchange of Definitive Notes for Beneficial Interests. Other than following an exchange of beneficial interest in a Global Note for Definitive Notes as contemplated by Section 3.06(a)(2), a Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.

(e) Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 3.06(e), the Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder must present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. A Holder of Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of a Definitive Note. Upon receipt of a request to register such a transfer, the Registrar shall register the Definitive Note pursuant to the instructions from the Holder thereof.

(f) Legends. In addition to the legend appearing on the face of the form of the Notes in Exhibit A hereto relating to original issue discount, the following legend will appear on the face of all Global Notes and Definitive Notes issued under the Indenture unless specifically stated otherwise in the applicable provisions of the Indenture.

(1) Global Note Legend. Each Global Note will bear a legend in substantially the following form:

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 3.06 OF THE INDENTURE, (2) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 3.06(a) OF THE INDENTURE, (3) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 3.11 OF THE INDENTURE AND (4) THIS

GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE ISSUER.

UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇) (“DTC”), TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

(g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for beneficial interests in another Global Note or Definitive Notes, or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 3.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(h) General Provisions Relating to Transfers and Exchanges.

(1) To permit registrations of transfers and exchanges, the Issuer will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 3.02 hereof or at the Registrar’s request.

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax

or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 3.10, 4.06 and 7.06 hereof).

(3) The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

(4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid Obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under the Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(5) Neither the Registrar nor the Issuer will be required:

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 4.02 hereof and ending at the close of business on the day of selection;

(B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

(6) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuer shall be affected by notice to the contrary.

(7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 3.02 hereof.

(8) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 3.06 to effect a registration of transfer or exchange may be submitted by facsimile or electronic image scan.

Section 3.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuer will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must

be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer may charge for its expenses in replacing a Note.

Every replacement Note is an additional Obligation of the Issuer and will be entitled to all of the benefits of the Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 3.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 3.08 as not outstanding. Except as set forth in Section 3.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or a Subsidiary of the Issuer shall not be deemed to be outstanding for purposes of Section 4.07(a) hereof.

If a Note is replaced pursuant to Section 3.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If the principal amount of any Note is considered paid under Section 5.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, by 11 a.m., New York City time, on a redemption date or other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 3.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or any Guarantor (if any), or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any Guarantor (if any), will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded.

Section 3.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will be entitled to all of the benefits of the Indenture.

Section 3.11 Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Issuer. The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 3.12 Defaulted Interest.

If the Issuer defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date. The Issuer will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 10 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 3.13 CUSIP Numbers.

The Issuer in issuing the Notes may use “CUSIP” or “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” or “ISIN” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other elements of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuers will promptly notify the Trustee in writing of any change in the “CUSIP” or “ISIN” numbers.

ARTICLE 4
REDEMPTION AND PREPAYMENT

Section 4.01 Notices to Trustee.

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 4.07 hereof, it must furnish to the Trustee, at least five Business Days prior to the giving of notice of a redemption, an Officers’ Certificate setting forth:

(a) the clause of the Indenture pursuant to which the redemption shall occur;

(b) the redemption date;

(d) the redemption price (if then determined and otherwise the method of determination).

Section 4.02 Selection of Notes to Be Redeemed.

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 3 hereof, by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law); provided, that no partial redemption of any Note will occur if such redemption would reduce the principal amount of such Note to less than $2,000.

If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption shall become due on the date fixed for redemption. Unless the Partnership defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions of the Notes called for redemption.

The Trustee will promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed. Except as provided in the preceding sentence, provisions of the Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 4.03 Notice of Redemption.

At least 30 days but not more than 60 days before a redemption date, the Issuer will mail or cause to be mailed by first class mail (or sent electronically if DTC is the recipient) a notice of redemption to each Holder whose Notes are 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 defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Article 9 hereof.

Any such redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent. If such redemption is subject to the satisfaction of one or more conditions precedent, the related notice shall describe each such condition, and if applicable, shall state that, in the Issuer’s discretion, the date of redemption may be delayed until such time as any or all such conditions shall

be satisfied or waived (provided that in no event shall such date of redemption be delayed to a date later than 60 days after the date on which such notice was mailed or sent), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the date of redemption, or by the date of redemption as so delayed.

The notice will identify the Notes to be redeemed and will state:

(a) the redemption date;

(b) the redemption price (if then determined and otherwise the method of determination);

(c) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued in the name of the Holder thereof upon cancellation of the original Note;

(d) the name and address of the Paying Agent;

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(f) that, unless the Issuer defaults in making such redemption payment, interest on Notes or portions thereof called for redemption ceases to accrue on and after the redemption date;

(g) the paragraph of the Notes and/or Section of the Indenture pursuant to which the Notes called for redemption are being redeemed;

(h) the CUSIP or ISIN number, if any; and

(i) that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number, if any, listed in such notice or printed on the Notes.

At the Issuer’s request, the Trustee will give the notice of redemption in the Issuer’s names and at the Issuer’s expense; provided, however, that the Officers’ Certificate delivered to the Trustee pursuant to Section 4.01 hereof requests that the Trustee give such notice and sets forth the information to be stated in such notice as provided in the preceding paragraph.

Section 4.04 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 4.03 hereof, Notes called for redemption become irrevocably due and payable (subject to the provisions of the second paragraph of Section 4.03) on the redemption date at the redemption price.

Section 4.05 Deposit of Redemption or Purchase Price.

No later than 11:00 a.m., New York City time, on the redemption or purchase date, the Issuer will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, and accrued interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest, if any, on all Notes to be redeemed or purchased.

If the Issuer complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or accepted for purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest, if any, shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or tendered for purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes.

Section 4.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Issuer will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Section 4.07 Optional Redemption.

(a) At any time prior to the Early Call Date, the Issuer may on any one or more occasions redeem the Notes, in whole or in part, at a redemption price, as determined by the Issuer, equal to the greater of:

(1) 100% of the principal amount of the Notes to be redeemed; or

(2) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed that would be due if such Notes matured on the Early Call Date but for the redemption (exclusive of any portion of the payments of interest accrued to the date of redemption), discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Yield plus 25 basis points,

in each case, together with accrued but unpaid interest thereon to, but not including, the redemption date.

(b) Except pursuant to Section 4.07(a), the Notes will not be redeemable at the Issuer’s option prior to the Early Call Date.

(c) On and after the Early Call Date, the Issuer may on any one or more occasions redeem all or a part of the Notes at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued but unpaid interest thereon to, but not including, the redemption date.

(d) Any redemption pursuant to this Section 4.07 shall be made pursuant to the provisions of Sections 4.01 through 4.06 hereof.

Section 4.08 Mandatory Redemption.

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

ARTICLE 5
COVENANTS

Section 5.01 Payment of Notes.

The Issuer will pay or cause to be paid the principal of and premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest, will be considered paid on the date due if the Paying Agent, if other than the Issuer or a Subsidiary of the Issuer, holds as of 11:00 a.m., New York City time, on the due date money deposited by the Issuer in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due.

The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium at a rate that is equal to the then applicable interest rate on the Notes to the extent lawful; the Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful.

Section 5.02 Maintenance of Office or Agency.

The Issuer will maintain in Houston, Texas, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and the Indenture may be served. The Issuer will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time

rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Issuer of its obligation to maintain an office or agency in Houston, Texas for such purposes. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

Section 5.03 Reports.

(a) So long as any Notes are outstanding, the Issuer shall:

(1) during such time as it is subject to the reporting requirements of the Exchange Act, file with the Trustee, within 30 days after it files the same with the SEC, copies of the annual reports and the information, documents and other reports that it is required to file with the SEC pursuant to the Exchange Act; and

(2) during such time as it is not subject to the reporting requirements of the Exchange Act, file with the Trustee, within 30 days after it would have been required to file the same with the SEC, financial statements, including any notes thereto (and with respect to annual reports, an auditors’ report by a firm of established national reputation) and a Management’s Discussion and Analysis of Financial Condition and Results of Operations, both comparable to what it would have been required to file with the SEC had it been subject to the reporting requirements of the Exchange Act.

(b) Notwithstanding the foregoing, reports, information and documents filed with the SEC via the ▇▇▇▇▇ system will be deemed to be delivered to the Trustee as of the time of such filing via ▇▇▇▇▇ for purposes of this Section 5.03, provided, that the Trustee shall have no responsibility to determine if such filing has occurred.

(c) Any and all Defaults or Events of Default arising from a failure to furnish or file in a timely manner a report or certification required by this Section 5.03 shall be deemed cured (and the Issuer shall be deemed to be in compliance with this Section 5.03) upon furnishing or filing such report or certification as contemplated by this Section 5.03 (but without regard to the date on which such report or certification is so furnished or filed); provided that such cure shall not otherwise affect the rights of the Holders under Article 7 of the Base Indenture if the principal, premium, if any, and interest have been accelerated in accordance with the terms of the Indenture and such acceleration has not been rescinded or cancelled prior to such cure.

(d) Delivery of any reports, information and documents to the Trustee, including pursuant to Section 5.03, is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants pursuant to Article 5 hereof (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 5.04 Compliance Certificate.

(a) The Issuer shall, so long as any Notes are outstanding, deliver to the Trustee, within 120 days after the end of each fiscal year of the Issuer, a statement signed by an Officer, which need not constitute an Officers’ Certificate, complying with TIA §314(a)(4) and stating that in the course of performance by the signing Officer of his or her duties as such Officer, he or she would normally obtain knowledge of the keeping, observing, performing and fulfilling by the Issuer of its obligations under the Indenture, and further stating that to the best of his or her knowledge the Issuer has kept, observed, performed and fulfilled each and every covenant contained in the Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which such Officer may have knowledge and what action the Issuer is taking or proposes to take with respect thereto).

(b) The Issuer will, so long as any Notes are outstanding, deliver to the Trustee, within 30 days of any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto.

Section 5.05 Further Instruments and Acts.

The Issuer shall, upon request of the Trustee, execute and deliver such further instruments and do such further acts as may reasonably be necessary or proper to carry out more effectually the purposes of the Indenture.

Section 5.06 Existence.

Subject to the provisions of Article VI, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence and all rights (charter and statutory) and franchises of the Issuer, provided that the Issuer shall not be required to preserve any such right or franchise if the Issuer shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer.

Section 5.07 Taxes.

The Issuer shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders.

Section 5.08 Waiver of Stay, Extension and Usury Laws.

The Issuer covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of the Indenture or the Notes; and the Issuer (to the extent it may

lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

Section 5.09 Liens.

(a) The Issuer will not, and will not permit any of its Principal Domestic Subsidiaries to, issue, assume or guarantee any Debt for borrowed money secured by any Lien upon any Principal Property of the Issuer or any of its Principal Domestic Subsidiaries, or upon any equity interests of any Principal Domestic Subsidiary, whether such Principal Property is, or equity interests are, owned on or acquired after the date of the Indenture, unless the Notes then outstanding are equally and ratably secured by such Lien for so long as any such Debt is so secured, other than:

(1) (a) Liens on assets (including improvements and accession thereto and proceeds thereof) existing at the time of the acquisition thereof and (b) conditional sales agreements or other title retention agreements and leases in the nature of title retention agreements with respect to any property hereafter acquired, and any additions thereto, proceeds thereof and property in replacement or substitution thereof, so long as no such Lien shall extend to or cover any other property of the Issuer or such Principal Domestic Subsidiary;

(2) Liens upon any property of the Issuer or any Principal Domestic Subsidiary or any equity interests of any Principal Domestic Subsidiary existing as of the date of the issuance of the Initial Notes;

(3) Liens upon the property or any equity interests of any entity, which Liens existed at the time such entity became a Subsidiary of the Issuer; provided, however, that such Liens only encumber the property or assets of such entity at the time such entity becomes a Subsidiary of the Issuer, and any additions thereto, proceeds thereof and property or assets in replacement or substitution thereof;

(4) Liens upon the property or assets of any entity at the time such entity is merged into or consolidated with the Issuer or any Subsidiary of the Issuer or at the time of a sale, lease or other disposition of the properties of an entity (or division thereof) as an entirety or substantially as an entirety to the Issuer or a Subsidiary of the Issuer; provided, however, that such Liens only encumber such entity or the property or assets of such entity, as applicable, at the time of such merger, consolidation or sale, lease or other disposition, and any additions thereto, proceeds thereof and property or assets in replacement or substitution thereof;

(5) Liens for taxes or assessments or other governmental charges or levies relating to amounts that are not yet delinquent or are being contested in good faith;

(10) easements (including, without limitation, reciprocal easement agreements and utility agreements), zoning restrictions, rights-of-way, covenants, consents, reservations, encroachments, variations and other restrictions on the use of property or minor irregularities in title thereto, charges or encumbrances (whether or not recorded) affecting the use of real property and which are incidental to, and do not materially impair the use of such property in the operation of the business of the Issuer and its Subsidiaries, taken as a whole, or the value of such property for the purpose of such business;

(11) Liens in favor of the United States of America, any State, any foreign country or any department, agency or instrumentality or political subdivision of any such jurisdiction, to secure partial, progress, advance or other payments pursuant to any contract or statute or to secure any Debt incurred for the purpose of financing all or any part of the purchase price or the cost of constructing or improving the property subject to such Liens, including, without limitation, Liens to secure Debt of the pollution control or industrial revenue bond type;

(12) Liens on assets (a) securing all or any portion of the cost of acquiring, constructing, improving, developing, repairing or expanding such assets or (b) securing Debt incurred prior to, at the time of, or within 12 months after the later of the acquisition, the completion of construction, improvement, development, repair or expansion or the commencement of commercial operations of such assets, for the purpose (in the case of this clause (b)) of (x) financing all or any part of the purchase price of such assets or (y) financing all or any part of the cost of construction, improvement, development, repair or expansion of any such assets;

(13) Liens in favor of the Issuer, one or more Principal Domestic Subsidiaries, one or more wholly owned Subsidiaries of the Issuer or any combination of the foregoing;

(14) the replacement, extension or renewal (or successive replacements, extensions or renewals), as a whole or in part, of any Lien, or of any agreement, referred to in clauses (1) through (13) above, or the replacement, extension or renewal of the Debt secured thereby (not exceeding the principal amount of Debt secured thereby, other than to provide for the payment of any underwriting or other fees related to any such replacement, extension or renewal, as well as any premiums owed on and accrued and unpaid interest payable in connection with any such replacement, extension or renewal); provided that such replacement, extension or renewal is limited to all or a part of the same property that secured the Lien replaced, extended or renewed (plus improvements thereon or additions or accessions thereto); or

(15) any Lien not excepted by the foregoing clauses; provided that immediately after the creation or assumption of such Lien the aggregate principal amount of Debt of the Issuer or any Principal Domestic Subsidiary secured by all Liens created or assumed under the provisions of this clause (15), together with all net sale proceeds from any Sale-Leaseback Transactions entered into pursuant Section 5.10(b) or 5.10(c) (reduced by the amounts applied pursuant to Section 5.10(c)) shall not exceed an amount equal to 15% of Consolidated Net Tangible Assets for the fiscal quarter that was most recently completed prior to the creation or assumption of such Lien.

(b) Notwithstanding the foregoing, for purposes of making the calculation set forth in clause (a)(15) of this Section 5.09, with respect to any such secured Debt of a non-wholly-owned Principal Domestic Subsidiary of the Issuer with no recourse to the Issuer or any wholly owned Principal Domestic Subsidiary thereof, only that portion of the aggregate principal amount of such secured Debt reflecting the Issuer’s pro rata ownership interest in such non-wholly-owned Principal Domestic Subsidiary shall be included in calculating compliance with this Section 5.09.

Section 5.10 Limitation on Sale-Leaseback Transactions.

The Issuer shall not, and shall not permit any of its Principal Domestic Subsidiaries to, engage in a Sale-Leaseback Transaction, unless:

(a) the Sale-Leaseback Transaction occurs within one year from the date of acquisition of the relevant Principal Property or the date of the completion of construction, development or substantial repair or improvement or commencement of full operations on such Principal Property, whichever is later;

(b) the Issuer or such Principal Domestic Subsidiary would be entitled under Section 5.09 to incur Debt secured by a Lien on the Principal Property subject to the Sale-Leaseback Transaction in a principal amount equal to or exceeding the net sale proceeds from such Sale-Leaseback Transaction without equally and ratably securing the notes; or

(c) the Issuer or such Principal Domestic Subsidiary, within a one year period after such Sale-Leaseback Transaction, applies or causes to be applied an amount equal to all or a portion of the net sale proceeds from such Sale-Leaseback Transaction (with any such amount not being so designated to be permitted as set forth in clause (b) of this Section 5.10) to (1) the prepayment, repayment, redemption or retirement of any Debt of the Issuer or any of its Subsidiaries that is not by its terms subordinated to the notes (x) for borrowed money or (y) evidenced by bonds, debentures, notes or other similar instruments, or (2) the acquisition, construction, improvement, repair or expansion of one or more Principal Properties.

Section 5.11 Future Guarantors.

As of the date of this Supplemental Indenture, the Notes shall not be Guaranteed by any of the Issuer’s existing Subsidiaries. If, after the date of this Supplemental Indenture, any of the Issuer’s Subsidiaries (other than ▇▇▇▇▇▇▇▇ 66 Partners Holdings LLC) Guarantees, becomes a borrower or guarantor under, or grants any Lien to secure any Obligations pursuant to, the Revolving Credit Facility, then the Issuer shall cause such Subsidiary to become a Guarantor by executing a supplement to the Indenture and delivering such supplement to the Trustee promptly (but in any event, within 30 days of the date on which it guaranteed or incurred such Obligations or granted such Lien, as the case may be).

ARTICLE 6

Section 6.01 Consolidation, Merger, Conveyance or Transfer.

(a) The Issuer may not consolidate with or merge with or into any other Person, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets and the properties or assets of its Subsidiaries (taken as a whole with the properties or assets of the Issuer) to another Person in one or more related transactions, unless:

(1) either: (a) in the case of a merger or consolidation, the Issuer is the surviving entity; or (b) the Person formed by or surviving any such consolidation or merger (if other than the Issuer) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a Person formed, organized or existing under the laws of the United States, any state thereof or the District of Columbia;

(2) the Person formed by or surviving any such consolidation or merger (if other than the Issuer) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made expressly assumes all of the Issuer’s Obligations under the Notes and the Indenture, including the Issuer’s Obligation to pay all principal of, premium, if any, and interest on, the Notes pursuant to the Indenture;

(3) the Issuer delivers an Officers’ Certificate and Opinion of Counsel to the Trustee, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and any supplemental indenture required in connection

therewith comply with the Indenture and that all conditions precedent set forth in the Indenture have been complied with; and

(4) immediately after giving effect to the transaction, no Event of Default or default under the Indenture will have occurred and be continuing.

Section 6.02 Successor Issuer Substituted.

Upon any consolidation or merger, or any sale, lease, conveyance or other disposition of all or substantially all of the assets, of the Issuer in accordance with Section 6.01, the successor person formed by such consolidation or into or with which the Issuer is merged or to which such sale, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under the Indenture with the same effect as if such successor person has been named as the Issuer herein; provided, however, that the predecessor Issuer in the case of a sale, conveyance or other disposition (other than a lease) shall be released from all obligations and covenants under the Indenture and the Notes.

ARTICLE 7
AMENDMENT, SUPPLEMENT AND WAIVER

Section 7.01 Without Consent of Holders of Notes.

Notwithstanding Section 7.02 of the Indenture, without the consent of any Holder of Notes, the Issuer, the Guarantors, if any, and the Trustee may amend or supplement the Indenture, the Notes or the Guarantees:

(a) to cure any ambiguity, defect or inconsistency;

(b) to comply with Article 6;

(d) to surrender any of the Issuer’s rights or powers under the Indenture;

(e) to add covenants or events of default for the benefit of the holders of Notes;

(f) to comply with the applicable procedures of the applicable Depositary;

(g) make any change that does not adversely affect the rights of any Holder as determined in good faith by the Issuer, as evidenced in an Officers’ Certificate delivered to the Trustee;

(h) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Notes and to add to or change any of the provisions of the Indenture to provide for or facilitate the administration of the trusts hereunder by more than one Trustee;

(i) to conform the text of the Indenture or the Notes to any provision of the “Description of Notes” section of the Issuer’s Prospectus Supplement dated February 18, 2015, relating to the offering of the Initial Notes;

(j) to comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA;

(k) to evidence the succession of another person to the Issuer, or successive successions, and the assumption by the successor person of the covenants, agreements and Obligations of such Issuer the pursuant to Article 6;

(l) to add any Guarantor or to evidence the release of any Guarantor from its Guarantee, in each case as provided in the Indenture; or

(m) to comply with the rules or regulations of any securities exchange or automated quotation system on which any of the Notes may be listed or traded.

Section 7.02 With Consent of Holders of Notes.

The Issuer and the Trustee may enter into a supplemental indenture with the written consent of the Holders of a majority in principal amount of the outstanding Notes affected by such supplemental indenture (including consents obtained in connection with a tender offer or exchange offer for the Notes), for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of Notes. Except as provided in Section 6.13 of the Base Indenture, the Holders of a majority in principal amount of the outstanding Notes by notice to the Trustee (including consents obtained in connection with a tender offer or exchange offer for the Notes) may waive compliance by the Issuer with any provision of the Indenture or the Notes.

It shall not be necessary for the consent of the Holders of Notes under this Section 7.02 to approve the particular form of any proposed supplemental indenture or waiver, but it shall be sufficient if such consent approves the substance thereof. After a supplemental indenture or waiver under this Section 7.02 becomes effective, the Issuer shall mail to the Holders of Notes affected thereby a notice briefly describing the supplemental indenture or waiver. Any failure by the Issuer to mail or publish such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.

Section 7.03 Limitations.

Without the consent of each Holder affected, an amendment or waiver may not:

(a) reduce the principal amount of the Notes whose Holders must consent to an amendment, supplement or waiver;

(b) reduce the rate of or extend the time for payment of interest (including default interest) on any Note;

(d) waive a Default or Event of Default in the payment of the principal of or interest, if any, on any Note (except in connection with a rescission of acceleration of the Notes by the Holders of a majority in principal amount of the outstanding Notes and a related waiver of the payment default that resulted from such acceleration);

(e) make the principal of or interest, if any, on any Note payable in any currency other than Dollars;

(f) make any change in Sections 6.08 or 6.13 of the Base Indenture or this clause (f); or

(g) waive a redemption payment with respect to any Note, provided that such redemption is made at the Issuer’s option.

Section 7.04 Compliance with Trust Indenture Act.

Every amendment to the Indenture or the Notes shall be set forth in a supplemental indenture hereto that complies with the TIA as then in effect.

Section 7.05 Revocation and Effect of Consents.

Until an amendment is set forth in a supplemental indenture or a waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder and every subsequent Holder of a Note or portion thereof that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to his Note or portion thereof if the Trustee receives the notice of revocation before the date of the supplemental indenture or the date the waiver becomes effective.

Any amendment or waiver once effective shall bind every Holder of Notes affected by such amendment or waiver unless it is of the type described in any of clauses (a) through (g) of Section 7.03. In that case, the amendment or waiver shall bind each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion thereof that evidences the same debt as the consenting Holder’s Note.

The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to the Indenture. If a record date is fixed, then notwithstanding 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 give such consent or to revoke any consent previously given or take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date unless consents from Holders of the principal amount of Notes required hereunder for such amendment or waiver to be effective shall have also been given and not revoked within such 120-day period.

Section 7.06 Notation on or Exchange of Notes.

The Issuer or the Trustee may place an appropriate notation about an amendment or waiver on any Notes thereafter authenticated. The Issuer in exchange for the Notes may issue and the Trustee shall authenticate upon request new Notes that reflect the amendment or waiver.

Section 7.07 Trustee Protected.

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article 10 or the modifications thereby of the trusts created by the Indenture, the Trustee shall be entitled to receive, and (subject to Section 7.1 of the Base Indenture) shall be fully protected in relying upon, an Opinion of Counsel or an Officers’ Certificate, or both, complying with Section 9.04 as conclusive evidence that such amendment or supplement is authorized or permitted by the Indenture. The Trustee shall sign all supplemental indentures upon delivery of such an Officers’ Certificate or Opinion of Counsel or both, except that the Trustee need not sign any supplemental indenture that adversely affects its rights.

ARTICLE 8
GUARANTEE

Section 8.01 Unconditional Guarantee.

(a) Notwithstanding any provision of this Article 7 to the contrary, the provisions of this Article 7 shall be applicable only if the Issuer is required to cause one of its Subsidiaries to deliver a supplemental indenture pursuant to Section 5.11.

(b) For value received, each Guarantor shall, jointly and severally, fully, unconditionally and absolutely guarantee to the Holders and to the Trustee the due and punctual payment of the principal of and interest on the Notes and all other amounts due and payable under the Indenture and the Notes by the Issuer, when and as such principal and interest shall become due and payable, whether on the Maturity Date or by declaration of acceleration, call for redemption or otherwise, according to the terms of such Notes and the Indenture, subject to the limitations set forth in Section 8.02.

(c) Failing payment when due of any amount guaranteed pursuant to the Guarantee, for whatever reason, each of the Guarantors will be jointly and severally obligated to pay the same immediately. Each of the Guarantors hereby agrees that its Obligations hereunder shall be full, unconditional and absolute, irrespective of the validity, regularity or enforceability of the Notes, the Guarantee (including the Guarantee of any other Guarantor) or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer or any other Guarantor, or any action to enforce the same or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of any of the Guarantors. Each Guarantor hereby agrees that, in the event of a default in payment of the principal of or interest on the Notes entitled to the Guarantee of such Guarantor, whether on the Maturity Date or by declaration of acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of

the Holders or, subject to Section 6.7 of the Base Indenture, by the Holders, on the terms and conditions set forth in the Indenture, directly against such Guarantor to enforce the Guarantee without first proceeding against the Issuer or any other Guarantor.

(d) Each Guarantor hereby (i) waives diligence, presentment, demand of payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Issuer or any of the Guarantors, and all demands whatsoever and (ii) acknowledges that any agreement, instrument or document evidencing the Guarantee may be transferred and that the benefit of its Obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Guarantee without notice to it. Each Guarantor further agrees that, if at any time all or any part of any payment theretofore applied by any person to the Guarantee is, or must be, rescinded or returned for any reason whatsoever, including, without limitation, the insolvency, bankruptcy or reorganization of the Issuer or any of the Guarantors, the Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Guarantee shall continue to be effective or be reinstated, as the case may be, as though such application had not been made.

(e) Each Guarantor shall be subrogated to all rights of the Holders and the Trustee against the Issuer in respect of any amounts paid by such Guarantor pursuant to the provisions of the Indenture and the Guarantee; provided, however, that such Guarantor shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until all of the Notes entitled to the Guarantee of such Guarantor and the Guarantee shall have been paid in full or discharged.

Section 8.02 Limitation on Guarantors’ Liability.

Each Guarantor by its acceptance hereof and each Holder of a Note entitled to the benefits of the Guarantee hereby confirms that it is the intention of all such parties that the guarantee by such Guarantor pursuant to the Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal or state law. To effectuate the foregoing intention, each Holder of a Note entitled to the benefits of the Guarantee and each Guarantor hereby irrevocably agrees that the Obligations of each Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and 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 the Guarantee, not result in the Obligations of such Guarantor under the Guarantee constituting a fraudulent conveyance or fraudulent transfer under federal or state law.

Section 8.03 Release of Guarantors from Guarantee.

(a) Notwithstanding any other provisions of the Indenture, the Guarantee of any Guarantor may be released upon the terms and subject to the conditions set forth in Sections 8.1, 8.3 and 8.4 of the Base Indenture and in this Section 8.03. Provided that no Default shall have occurred and shall be continuing under the Indenture, the Guarantee incurred by a Guarantor pursuant to this Article 8 shall be unconditionally released and discharged

(1) in connection with any sale or other disposition of all or substantially all of the properties or assets of, or all of our direct or indirect limited partnership, limited liability company or other equity interests in, that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) an Affiliate of the Issuer;

(2) upon the merger of the Guarantor into us or any other Guarantor or the liquidation or dissolution of the Guarantor; or

(3) upon delivery of written notice to the Trustee of the release of all guarantees or other Obligations of the Guarantor under our Revolving Credit Facility.

(b) Upon receipt of a written request of the Issuer accompanied by an Officers’ Certificate and an Opinion of Counsel to the effect that any Guarantor is entitled to release from the Guarantee in accordance with the provisions of the Indenture, the Trustee shall sign an appropriate instrument delivered to it evidencing the release of such Guarantor from the Guarantee. Any Guarantor not so released shall remain liable for the full amount of principal of and interest on the Notes entitled to the benefits of the Guarantee as provided in the Indenture, subject to the limitations of Section 8.02.

(c) If at any time following any release of a Guarantor from its guarantee of the notes pursuant to Section 7.03(a)(3), such entity again guarantees Obligations under our Revolving Credit Facility, then the Issuer shall cause such entity to again guarantee the Notes in accordance with the Indenture.

The Issuer or the Trustee by notice to the others may designate additional or different addresses for subsequent notices or communications.

Any notice or communication to a Holder shall be sent electronically or by first-class mail to his address shown on the register kept by the Registrar. Failure to mail a notice or communication to a Holder of any Notes or any defect in it shall not affect its sufficiency with respect to other Holders of that or any other Notes.

If a notice or communication is sent or published in the manner provided above, within the time prescribed, it is duly given, whether or not the Holder receives it.

If the Issuer sends a notice or communication to Holders, it shall send a copy to the Trustee and each Agent at the same time.

Notwithstanding any other provision of the Indenture or any Note, where the Indenture or any Note provides for notice of any event (including any notice of redemption) to a Holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given to the Depositary for such Note (or its designee) pursuant to the customary procedures of such Depositary.

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods; provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced

whenever a person is to be added or deleted from the listing. If the Issuer elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The Issuer agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

Section 9.03 Communication by Holders with Other Holders.

Section 9.11 No Adverse Interpretation of Other Agreements.

Section 9.12 Successors.

All agreements of the Issuer and the Guarantors in the Indenture and the Notes shall bind their respective successors. All agreements of the Trustee in the Indenture shall bind its successor.

Section 9.13 Severability.

In case any provision in the Indenture or in the Notes 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.

Section 9.14 Table of Contents, Headings, Etc.

The Table of Contents, Cross Reference Table, and headings of the Articles and Sections of the Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof.

Section 9.15 Waiver of Jury Trial.

EACH OF THE ISSUER, THE GUARANTORS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THE INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 9.16 Act of Holders.

Any request, demand, authorization, direction, notice, consent, waiver or other action provided by the Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of the Indenture and conclusive in favor of the Trustee, the Issuer and the Guarantors, if made in the manner provided in this Section 9.16.

The fact and date of the execution by any person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such officer the execution thereof. Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer’s authority. The fact and date of the execution of any such instrument or writing, or the authority of the person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

The ownership of Notes shall be proved by the Holder list maintained under Section 3.05 hereunder.

Any request, demand, authorization, direction, notice, consent, waiver or other act of the Holder of Notes shall bind every future Holder of the same Notes and the holder of each Notes issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Notes.

If the Issuer shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuer may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Issuer shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of the Indenture not later than six months after the record date.

The Depositary, as a Holder, may appoint agents and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under the Indenture.

Section 9.17 Judgment Currency.

The Issuer agrees, to the fullest extent that it may effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of or interest or other amount on the Notes (the “Required Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures a person could purchase in The City of New York the Required Currency with the Judgment Currency on the day on which final unappealable judgment is entered, unless such day is not a New York Banking Day, then, the rate of exchange used shall be the rate at which in accordance with normal banking procedures a person could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Banking Day preceding the day on which final unappealable judgment is entered and (b) its Obligations under the Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, any recovery pursuant to any judgment (whether or not entered in accordance with subsection (a)), in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full

amount of the Required Currency so expressed to be payable, and (iii) shall not be affected by judgment being obtained for any other sum due under the Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of New York on which banking institutions are authorized or required by law, regulation or executive order to close.

Section 9.18 Force Majeure.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of god, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

Section 9.19 FATCA

In order to comply with applicable tax laws, rules and regulations under Sections 1471-1474 of the Code (including directives, guidelines and interpretations promulgated by competent authorities), in effect from time to time (“FATCA”), the Issuer agrees (i) upon request, to provide to the Trustee any tax-related information about Holders or any taxable transactions contemplated hereby (including any modification to the terms of such transactions), to the extent such information is directly available to the Issuer, so that the Trustee can determine whether it has tax-related obligations under FATCA and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments to Holders under the Indenture to the extent necessary to comply with FATCA.

(1)INTEREST. ▇▇▇▇▇▇▇▇ 66 Partners LP (the “Issuer”) promises to pay or cause to be paid interest on the principal amount of this Note at 3.605% per annum from February 23, 2015 until maturity. The Issuer will pay interest semi-annually in arrears on February 15 and August 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be August 15, 2015. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time at a rate that is equal to the then applicable interest rate on the Notes to the extent lawful; the Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), from time to time at the same rate to the extent lawful.

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

(2) METHOD OF PAYMENT. The Issuer will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the February 1 and August 1 immediately preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 3.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Issuer maintained for such purpose within Houston, Texas, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium, if any, on, or interest on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent.

(3) PAYING AGENT AND REGISTRAR. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change the Paying Agent or Registrar without notice to any Holder. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

(4) INDENTURE. The Issuer issued the Notes under an Indenture dated as of February 23, 2015 (the “Base Indenture”) among the Issuer and the Trustee, as amended and supplemented by the Second Supplemental Indenture thereto of even date therewith (the Base Indenture, as so supplemented and amended, the “Indenture”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured Obligations of the Issuer. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

(5) OPTIONAL REDEMPTION.

(a) At any time prior to November 15, 2024 (the “Early Call Date”), the Issuer may on any one or more occasions redeem the Notes, in whole or in part, at a redemption price, as determined by the Issuer, equal to the greater of:

(A) 100% of the principal amount of the Notes to be redeemed; or

(B) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed that would be due if such Notes matured on the Early Call Date but for the redemption (exclusive of any portion of the payments of interest accrued to the date of redemption), discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Yield plus 25 basis points, in each case, together with accrued but unpaid interest thereon to, but not including, the redemption date.

(b) Except pursuant to the preceding paragraphs, the Notes will not be redeemable at the Issuer’s option prior to the Early Call Date.

(c) On and after the Early Call Date, the Issuer may on any one or more occasions redeem all or a part of the Notes, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued but unpaid interest thereon to, but not including, the redemption date.

(6) MANDATORY REDEMPTION. The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

A-4

(7) NOTICE OF REDEMPTION. At least 30 days but not more than 60 days before a redemption date, the Issuer will mail or cause to be mailed by first class mail (or sent electronically if DTC is the recipient) a notice of redemption to each Holder whose Notes are 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 defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Article 9 thereof. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, 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. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of all the Holders, rescind an acceleration or waive an existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the
