          FIRST SUPPLEMENTAL INDENTURE dated as of May 18, 2011 (this “Supplemental Indenture”) among WESTERN GAS PARTNERS, LP, a Delaware limited partnership (the “Partnership”), the subsidiary guarantors signatory hereto (the “Subsidiary Guarantors”) and WELLS FARGO BANK, NATIONAL ASSOCIATION, as trustee (the “Trustee”).
W I T N E S S E T H:
          WHEREAS, the Partnership and Subsidiary Guarantors have heretofore entered into an Indenture, dated as of May 18, 2011 (the “Base Indenture”), with Wells Fargo Bank, National Association, as trustee;
          WHEREAS, the Base Indenture, as supplemented by this Supplemental Indenture, is herein called the “Indenture;”
          WHEREAS, under the Base Indenture, a new series of Debt Securities may at any time be established by the Board of Directors of the general partner of the Partnership in accordance with the provisions of the Base Indenture and the form and terms of such series may be established by a supplemental indenture executed by the Partnership and the Trustee;
          WHEREAS, also under the Base Indenture, a series of Debt Securities may be entitled to the benefit of the Guarantees of the Subsidiary Guarantors as set forth in Article XIV of the Base Indenture, which entitlement shall be so designated in the supplemental indenture related to such Debt Securities;
          WHEREAS, the Partnership proposes to create under the Indenture a new series of Debt Securities, such series to be guaranteed by the Subsidiary Guarantors;
          WHEREAS, additional Debt Securities of other series hereafter established, except as may be limited in the Base Indenture as at the time supplemented and modified, may be issued from time to time pursuant to the Base Indenture as at the time supplemented and modified; and
          WHEREAS, all conditions necessary to authorize the execution and delivery of this Supplemental Indenture and to make it a valid and binding obligation of the Partnership and the Subsidiary Guarantors have been done or performed.
          NOW, THEREFORE, in consideration of the agreements and obligations set forth herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:

               (d) Each Note shall be dated the date of authentication thereof and shall bear interest from the date of original issuance thereof or from the most recent date to which interest has been paid or duly provided for.
               (e) If and to the extent that the provisions of the Base Indenture are duplicative of, or in contradiction with, the provisions of this Supplemental Indenture, the provisions of this Supplemental Indenture shall govern.

     “Comparable Treasury Price” means, with respect to any redemption date for Notes, (1) the average of four Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest of all of the Reference Treasury Dealer Quotations or (2) if the Quotation Agent obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

     “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding the redemption date.

ARTICLE IV
REDEMPTION AND PREPAYMENT
          Section 4.01. Optional Redemption.
               (a) The Partnership may redeem the Notes, in whole or in part at any time before March 1, 2021, at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes (exclusive of interest accrued to the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 40 basis points, plus, in either case, accrued and unpaid interest, if any, on the principal amount being redeemed to such redemption date. On or after March 1, 2021, the Notes shall be redeemable and repayable, at the Partnership’s option, at any time in whole, or from time to time in part, at a price equal to 100% of the principal amount of the Notes to be redeemed plus accrued interest on the Notes to be redeemed to the date of redemption.
               (b) If fewer than all of the Notes are to be redeemed at any time, such Notes shall be selected for redemption not more than 60 days prior to the redemption date and such

6


 

selection shall be made by the Trustee on a pro rata basis, by lot or by such other method as the Trustee deems appropriate (or, in the case of Notes represented by a Note in global form, by such method as DTC may require); 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. Notices of redemption with respect to the Notes shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each holder of Notes to be redeemed at its registered address.
               (c) 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 shall 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 shall cease to accrue on the Notes or portions of the Notes called for redemption.
               (d) The provisions of Article III of the Base Indenture in respect of the Notes shall apply to any optional redemption of the Notes except when such provisions conflict with the foregoing.
ARTICLE V
COVENANTS
          The following covenants, in addition to the covenants set forth in Article IV of the Base Indenture, shall apply to the Notes:
          Section 5.01. Limitations on Liens. While any of the Notes remain outstanding, the Partnership shall not, and shall not permit any of its Principal Subsidiaries to, create, or permit to be created or to exist, any mortgage, lien, pledge, security interest, charge, adverse claim, or other encumbrance (“Lien”) upon any Principal Property of the Partnership or any of its Principal Subsidiaries, or upon any equity interests of any Principal Subsidiary, whether such Principal Property is, or equity interests are, owned on or acquired after the date of the Indenture, to secure any Debt, 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:
               (a) purchase money mortgages, or other purchase money Liens of any kind upon property acquired by the Partnership or any Principal Subsidiary after the date of the Indenture, or Liens of any kind existing on any property or any equity interests at the time of the acquisition thereof (including Liens that exist on any property or any equity interests of a Person that is consolidated with or merged with or into the Partnership or any Principal Subsidiary or that transfers or leases all or substantially all of its properties or assets to the Partnership or any Principal Subsidiary), or conditional sales agreements or other title retention agreements and leases in the nature of title retention agreements with respect to any property hereafter acquired, so long as no such Lien shall extend to or cover any other property of the Partnership or such Principal Subsidiary;

7


 

               (b) Liens upon any property of the Partnership or any Principal Subsidiary or any equity interests of any Principal Subsidiary existing as of the date of the initial issuance of the Notes or upon the property or any equity interests of any entity, which Liens existed at the time such entity became a Subsidiary of the Partnership;

               (e) builders’, materialmen’s, mechanics’, carriers’, warehousemen’s, workers’, repairmen’s, operators’, landlords’ or other similar Liens, in the ordinary course of business;
               (f) Liens created by or resulting from any litigation or proceeding that at the time is being contested in good faith by appropriate proceedings, including Liens relating to judgments thereunder as to which the Partnership or any Principal Subsidiary has not exhausted its appellate rights;
               (g) Liens on deposits required by any Person with whom the Partnership or any Principal Subsidiary enters into forward contracts, futures contracts, swap agreements or other commodities contracts in the ordinary course of business and in accordance with established risk management policies and Liens in connection with leases (other than capital leases) made, or existing on property acquired, in the ordinary course of business;
               (h) 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 Partnership and its Subsidiaries, taken as a whole, or the value of such property for the purpose of such business;
               (i) 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;

8


 

               (j) Liens of any kind upon any property acquired, constructed, developed or improved by the Partnership or any Principal Subsidiary (whether alone or in association with others) after the date of the Indenture that are created prior to, at the time of, or within 12 months after such acquisition (or in the case of property constructed, developed or improved, after the completion of such construction, development or improvement and commencement of full commercial operation of such property, whichever is later) to secure or provide for the payment of any part of the purchase price or cost thereof; provided that in the case of such construction, development or improvement the Liens shall not apply to any property theretofore owned by the Partnership or any Principal Subsidiary other than theretofore unimproved real property;
               (k) Liens in favor of the Partnership, one or more Principal Subsidiaries, one or more wholly-owned Subsidiaries of the Partnership or any of the foregoing in combination;
               (l) 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 the clauses 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
               (m) 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 Partnership or any Principal Subsidiary secured by all Liens created or assumed under the provisions of this clause, together with all net sale proceeds from any Sale-Leaseback Transactions, subject to certain exceptions, shall not exceed an amount equal to 15% of the Consolidated Net Tangible Assets for the fiscal quarter that was most recently completed prior to the creation or assumption of such Lien.
          Notwithstanding the foregoing, for purposes of making the calculation set forth in clause (m) of the preceding paragraph, with respect to any such secured Debt of a non-wholly-owned Principal Subsidiary of the Partnership with no recourse to the Partnership or any wholly-owned Principal Subsidiary thereof, only that portion of the aggregate principal amount of such secured Debt reflecting the Partnership’s pro rata ownership interest in such non-wholly-owned Principal Subsidiary shall be included in calculating compliance herewith.
          Section 5.02. Restriction of Sale-Leaseback Transactions. While the Notes remain outstanding, the Partnership shall not, and shall not permit any of its Principal 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 or commencement of full operations on such Principal Property, whichever is later, and the Partnership has elected to designate, as a credit against (but not exceeding) the purchase price

9


 

or cost of construction of such Principal Property, 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 applied as set forth in clause (c) below);
               (b) the Partnership or such Principal Subsidiary would be entitled 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 Partnership or such Principal Subsidiary, within a 270-day period after such Sale-Leaseback Transaction, applies or causes to be applied an amount not less than the net sale proceeds from such Sale-Leaseback Transaction to (1) the prepayment, repayment, redemption or retirement of any unsubordinated Debt of the Partnership or any of its Subsidiaries (A) for borrowed money or (B) evidenced by bonds, debentures, notes or other similar instruments, or (2) invest in another Principal Property.
          Section 5.03. Reports. So long as any Notes are outstanding, the Partnership shall:
               (a) during such time as it is subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), file with the Trustee, within 15 days after it files the same with the SEC, copies of the annual reports and the information, documents and other reports which it is required to file with the SEC pursuant to the Exchange Act; and
               (b) during such time as it is not subject to the reporting requirements of the Exchange Act, file with the Trustee, within 15 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.
          With respect to the Notes, the provisions of this Section 5.03 shall replace and preempt the provisions of Section 4.05(a) of the Base Indenture in their entirety.
          Section 5.04. Additional Subsidiary Guarantors. If, after the date of the Indenture, any of the Partnership’s Subsidiaries that is not already a Subsidiary Guarantor guarantees, becomes a borrower or guarantor under, or grants any Lien to secure any obligations pursuant to, the Revolving Credit Facility, then the Partnership shall cause such Subsidiary to become a Subsidiary Guarantor by executing a supplement to the Indenture and delivering such supplement to the Trustee promptly (but in any event, within ten business days of the date on which it guaranteed or incurred such obligations or granted such Lien, as the case may be).
          Section 5.05. Consolidation, Merger, Conveyance or Transfer of Subsidiary Guarantors. No Subsidiary Guarantor shall 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

10


 

properties or assets of such Subsidiary Guarantor) to another Person in one or more related transactions unless:
               (a) either: (i) in the case of a merger or consolidation, such Subsidiary Guarantor is the survivor; or (ii) the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) 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;
               (b) the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor), or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made, expressly assumes all of such Subsidiary Guarantor’s obligations under its Guarantee and the Indenture pursuant to a supplemental indenture;
               (c) the Subsidiary Guarantor or the successor Person 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
               (d) immediately after giving effect to the transaction, no Event of Default or default under the Indenture will have occurred and be continuing.
          Upon the assumption of any Subsidiary Guarantor’s obligations under the Indenture by a successor, such Subsidiary Guarantor shall be discharged from all obligations under the Indenture.
ARTICLE VI
SUCCESSORS

          Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.
          1. Interest. Western Gas Partners, LP, a Delaware limited partnership (the “Partnership”) promises to pay interest on the principal amount of this Note at 5.375% per annum from May 18, 2011 until maturity. The Partnership shall pay interest semi-annually on June 1 and December 1 of each such 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 shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance. The first Interest Payment Date shall be December 1, 2011.
          2. Method of Payment. The Partnership shall pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15 next 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 2.17 of the Base Indenture with respect to defaulted interest, and the Partnership shall pay principal (and premium, if any) of the Notes upon surrender thereof to the Trustee or a paying agent on or after June 1, 2011. The Notes shall be payable as to principal, premium, if any, and interest at the office or agency of the Trustee maintained for such purpose within or without The City and State of New York, or, at the option of the Partnership, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds shall be
 
2   To be included only if the Note is issued in global form.

A-2


 

required with respect to principal of and interest and premium, if any, on, each Global Security and all other Notes the Holders of which shall have provided wire transfer instructions to the Partnership or the paying agent on or prior to the applicable record date. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.
          3. Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, shall act as paying agent and Registrar. The Partnership may change any paying agent or Registrar without notice to any Holder. The Partnership or any of its Subsidiaries may act in any such capacity.
          4. Indenture. The Partnership issued the Notes under an Indenture dated as of May 18, 2011 (the “Base Indenture”), as supplemented by the First Supplemental Indenture dated as of May 18, 2011 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) among the Partnership, the Trustee and the subsidiary guarantors signatory thereto (the “Subsidiary Guarantors”). 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, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act 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 obligations of the Partnership initially in aggregate principal amount of $500 million. The Partnership may issue an unlimited aggregate principal amount of Additional Notes under the Indenture. Any such Additional Notes that are actually issued shall be treated as issued and outstanding Notes (and as the same series (with identical terms other than with respect to the issue date, the date of first payment of interest, if applicable, and the payment of interest accruing prior to the issue date) as the initial Notes) for all purposes of the Indenture, including waivers, amendments, redemptions and offers to purchase. To secure the due and punctual payment of the principal and interest on the Notes and all other amounts payable by the Partnership under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Subsidiary Guarantors have unconditionally guaranteed the Note Obligations under the Indenture and the Notes on a senior basis pursuant to the terms of the Indenture.
          5. Optional Redemption. The Partnership may redeem the Notes, in whole or in part at any time before March 1, 2021, at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes (exclusive of interest accrued to the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 40 basis points, plus, in either case, accrued and unpaid interest, if any, on the principal amount being redeemed to such redemption date. On or after March 1, 2021, the Notes shall be redeemable and repayable, at the Partnership’s option, at any time in whole, or from time to time in part, at a price equal to 100% of the principal amount of the Notes to be redeemed plus accrued interest on the Notes to be redeemed to the date of redemption.

A-3


 

          For purposes of determining any redemption price, the following definitions shall apply:
          “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes; provided, however, that if no maturity is within three months before or after the maturity date for such Notes, yields for the two published maturities most closely corresponding to such United States Treasury security shall be determined and the Treasury Rate shall be interpolated or extrapolated from those yields on a straight line basis rounding to the nearest month.
          “Comparable Treasury Price” means, with respect to any redemption date for Notes, (1) the average of four Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest of all of the Reference Treasury Dealer Quotations or (2) if the Quotation Agent obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.
          “Quotation Agent” means the Reference Treasury Dealer appointed by the Partnership.
          “Reference Treasury Dealer” means (i) each of Morgan Stanley & Co. Incorporated and one U.S. government securities dealer in The City of New York (a “Primary Treasury Dealer”) selected by Wells Fargo Securities, LLC, and their respective successors; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Partnership shall substitute therefor another Primary Treasury Dealer and (ii) two other Primary Treasury Dealers selected by the Partnership.
          “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding the redemption date.
          “Treasury Rate” means, with respect to any redemption date, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Partnership shall calculate the Treasury Rate on the third business day preceding any redemption date and notify the Trustee in writing of the Treasury Rate prior to the redemption.
          6. Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Unless the Partnership default in payment of the redemption

A-4


 

price, on and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption.
          7. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Partnership may require a Holder to pay any taxes or other governmental charges required by law or permitted by the Indenture. The Partnership need not exchange or register the transfer of any Note or portion of a Note selected for redemption or repurchase, except for the unredeemed or unrepurchased portion of any Note being redeemed or repurchased in part. Also, the Partnership need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or repurchased or during the period between a record date and the corresponding Interest Payment Date.
          8. Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes.
          9. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of a majority in aggregate principal amount of the then Outstanding Notes, and any existing default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the then Outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented for any of the purposes set forth in Section 9.01 of the Base Indenture (as amended by the Supplemental Indenture), including to cure any ambiguity, defect or inconsistency, to provide for the assumption of the Partnership’s obligations to Holders of the Notes in case of a merger or consolidation of the Partnership or sale of all or substantially all of the Partnership’s assets, to add or release Subsidiary Guarantors (or their successors) pursuant to the terms of the Indenture, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any Holder of the Notes, to comply with the requirements of the Commission to permit the qualification of the Indenture under the Trust Indenture Act, to evidence or provide for the acceptance of appointment under the Indenture of a successor Trustee, to add any additional Events of Default, to secure the Notes or the Guarantees or to establish the form or terms of any other series of Debt Securities.
          10. Defaults and Remedies. Events of Default with respect to the Notes include: (i) default for 30 days in the payment when due of interest on the Notes; (ii) default in payment when due of principal of or premium, if any, on the Notes at maturity, upon redemption or otherwise, (iii) failure by the Partnership or any Subsidiary Guarantor for 60 days after notice to comply with any of the other agreements in the Indenture; (iv) except as permitted by the Indenture, any Guarantee shall cease for any reason to be in full force and effect (except as otherwise provided in the Indenture) or is declared null and void in a judicial proceeding or any Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary Guarantor, shall deny or disaffirm its obligations under the Indenture or its Guarantee and (v) certain events of bankruptcy

A-5


 

or insolvency with respect to the Partnership or any of the Subsidiary Guarantors. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare all the Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency of either the Partnership or a Subsidiary Guarantor, all Outstanding Notes shall become due and payable without further action or notice. 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 Trustee in its exercise of any trust or power. If and so long as the board of directors, an executive committee of the board of directors or trust committee of Responsible Officers of the Trustee in good faith so determines, the Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interests. The Holders of a majority in aggregate principal amount of the Notes then Outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any past Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, the principal of, or premium, if any, on the Notes or except as otherwise specified in Section 6.06 of the Base Indenture. The Partnership and the Subsidiary Guarantors are required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Partnership is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.
          11. Trustee Dealings with the Partnership. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Partnership or its Affiliates, and may otherwise deal with the Partnership or its Affiliates, as if it were not the Trustee.
          12. No Recourse Against Others. The partners (other than the General Partner), directors, officers, employees, incorporators and members of each of the Partnership and the Subsidiary Guarantors, as such, shall have no liability for any obligations of the Subsidiary Guarantors or the Partnership under the Debt Securities, this Indenture or any Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting a Debt Security, each Holder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Debt Securities.
          13. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.
          14. Abbreviations. 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 right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).
          15. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Partnership has caused CUSIP and corresponding ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP and corresponding ISIN numbers in notices of redemption as a convenience to Holders. No
