This restriction shall not apply to or prevent the creation or existence of:

(a) any Lien on any property or assets of the Partnership or any Restricted Subsidiary in existence on the Issue Date or created pursuant to an “after-acquired property” clause or similar term in existence on the Issue Date in any mortgage, pledge agreement, security agreement or other similar instrument applicable to the Partnership or any Restricted Subsidiary and in existence on the Issue Date;

(f) any Lien in favor of the Partnership or any Restricted Subsidiary;

(g) any Lien created or assumed by the Partnership or any Restricted Subsidiary in connection with the issuance of Debt the interest on which is excludable from gross income of the holder of such Debt pursuant to the Internal Revenue Code of 1986, as amended, or any successor statute, for the purpose of financing, in whole or in part, the acquisition or construction of property or assets to be used by the Partnership or any Subsidiary;

(h) Permitted Liens;

(i) any Lien on any additions, improvements, replacements, repairs, fixtures, appurtenances or component parts thereof, attaching to or required to be attached to property or assets pursuant to the terms of any mortgage, pledge agreement, security agreement or other similar instrument, creating a Lien upon such property or assets permitted by Clauses (a) through (h), inclusive, of this Section; or

(j) any extension, renewal, refinancing, refunding or replacement (or successive extensions, renewals, refinancings, refundings or replacements) of any Lien, in whole or in part, that is referred to in Clauses (a) through (i), inclusive, of this Section, or of any Debt secured thereby; provided, however, that the principal amount of Debt secured thereby shall not exceed the greater of (1) the principal amount of Debt so secured at the time of such extension, renewal, refinancing, refunding or replacement

(plus the aggregate amount of premiums, other payments, costs and expenses required to be paid or incurred in connection with such extension, renewal, refinancing, refunding or replacement) and (2) the maximum committed principal amount of Debt so secured at such time; provided further, however, that such extension, renewal, refinancing, refunding or replacement shall be limited to all or a part of the property or assets (including improvements, alterations and repairs on such property or assets) subject to the Lien so extended, renewed, refinanced, refunded or replaced (plus improvements, alterations and repairs on such property or assets).

Notwithstanding the foregoing provisions of this Section, the Partnership may, and may permit any Subsidiary to, create, assume, incur or suffer to exist any Lien upon any Principal Property or capital stock of a Restricted Subsidiary to secure Debt of the Partnership or any other Person (other than the Debt Securities) that is not excepted by Clauses (a) through (j), inclusive, of this Section without securing the Debt Securities issued hereunder, provided that the aggregate principal amount of all Debt then outstanding secured by such Lien and all other Liens not excepted by Clauses (a) through (j), inclusive, of this Section, together with all net sale proceeds from Sale-Leaseback Transactions (excluding Sale-Leaseback Transactions permitted by Clauses (a) through (d), inclusive, of Section 4.10), does not exceed at any one time 15% of Consolidated Net Tangible Assets.

(b) the Sale-Leaseback Transaction involves a lease for a period, including renewals, of not more than three years;

(c) the Partnership or such Restricted Subsidiary would be entitled under Section 4.09 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 Debt Securities; or

(d) the Partnership or such Restricted Subsidiary, within a one-year 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 Funded Debt of the Partnership or any Funded Debt of a Subsidiary of the Partnership, or (2) investment in another Principal Property.

Notwithstanding the foregoing provisions of this Section, the Partnership may, and may permit any Restricted Subsidiary to, effect any Sale-Leaseback Transaction that is not excepted by Clauses (a) through (d), inclusive, of this Section, provided that the net sale proceeds from such Sale-Leaseback Transaction, together with the aggregate principal amount of then outstanding Debt (other than the Debt Securities) secured by Liens upon Principal Properties not excepted by Clauses (a) through (j), inclusive, of Section 4.09, do not exceed at any one time 15% of Consolidated Net Tangible Assets.

Section 4.11. Compliance with and Modification of Organizational Documents. The Partnership shall comply with the terms and provisions of Sections 2.9, 7.9 and 12.9 of its Fifth Amended and Restated Agreement of Limited Partnership, dated as of September 28, 2009, as amended, and shall not amend, supplement or otherwise modify (pursuant to a waiver or otherwise) any of such Sections in a manner materially adverse to the interests of the Holders of the Notes unless the Partnership obtains a Ratings Affirmation in connection with any such amendment, supplement or modification or failure to comply.”

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, U.S. Bank National Association, the Trustee under the Indenture, shall act as paying agent and Registrar. The Issuer may change any paying agent or Registrar without notice to any Holder. The Partnership may act in any such capacity.

4. Indenture. The Issuer issued the Notes under an Indenture dated as of August 11, 2010 (the “Original Indenture”), as amended and supplemented by the Sixth Supplemental Indenture, dated as of February 29, 2016 (the “Sixth Supplemental Indenture,” and, together with the Original Indenture the “Indenture”) between the Issuer and the Trustee.

The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a complete 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 the obligation of the Issuer, initially issued in the aggregate principal amount of $650.0 million. The Issuer 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 the same terms (except for the issue date of such Additional Notes, the public offering price of such Additional Notes and, if applicable, the date for the first payment of interest following the issue date of such Additional Notes) as the initial Notes for the purposes indicated in Section 3.02 of the Sixth Supplemental Indenture). Initially, the Notes are not guaranteed, but in the future they may be guaranteed by one or more Subsidiary Guarantors on the conditions and subject to the terms provided in Section 4.08 (which is set forth in Section 5.01 of the Sixth Supplemental Indenture) and Article XIV of the Original Indenture.

5. Optional Redemption. (a) At any time prior to December 1, 2025 (the date that is three months prior to the Stated Maturity), at its option, the Issuer may choose to redeem all or any portion of the Notes, at once or from time to time, at a redemption price determined by the

Exhibit A-3

Issuer equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed that would be due if the Notes matured on December 1, 2025, but for the redemption (exclusive of interest accrued to such Redemption Date), discounted to such Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points, plus, in either case, accrued and unpaid interest, if any, to such Redemption Date.

For purposes of determining the redemption price, the following definitions shall apply:

“Comparable Treasury Issue” means the U.S. Treasury security or securities selected by the Independent Investment Banker as having an actual or interpolated 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 a comparable maturity to the remaining term of the Notes to be redeemed.

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of five 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 Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means Barclays Capital Inc., U.S. Bancorp Investments, Inc. or ▇▇▇▇▇ Fargo Securities, LLC, or any of their respective successor firms, or if each such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Trustee after consultation with the Partnership.

“Primary Treasury Dealer” means a primary U.S. government securities dealer in New York City.

“Reference Treasury Dealer” means each of (1) Barclays Capital Inc. or any of its successors; (2) a Primary Treasury Dealer selected by U.S. Bancorp Investments, Inc. or any of its successors; (3) a Primary Treasury Dealer selected by ▇▇▇▇▇ Fargo Securities, LLC or any of its successors; and (4) two other Primary Treasury Dealers (in each case, or its affiliates and successors) that the Issuer specifies from time to time, provided that if any of the Reference Treasury Dealers specifically named above resigns, its successor dealer shall be a Primary Treasury Dealer selected by the Trustee.

“Reference Treasury Dealer Quotations” means, for each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and ask prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date.

Exhibit A-4

“Treasury Rate” means, with respect to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes to be redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week in which the calculation date falls (or in the immediately preceding week if the calculation date falls on any day prior to the usual publication date for such release) or does not contain such yields, the rate per year equal to the semi-annual 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 Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. Any weekly average yields calculated by interpolation or extrapolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200th of 1% or above being rounded upward.

6. Mandatory Redemption. The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase them at the option of the Holders.

7. Notice of Redemption. Notice of redemption shall be mailed by first class mail 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.

On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption and with respect to which the redemption price has been paid.

8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture.

9. Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes.

10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture may be amended or supplemented with the consent of the Holders of not less than a majority in

Without the consent of any Holder of a Note, the Indenture may be amended or supplemented for any of the purposes set forth in Section 9.01 of the Indenture, including to provide for the assumption of the Issuer’s obligations to Holders of the Notes in case of a merger or consolidation of the Issuer or sale of all or substantially all of the Issuer’s assets, to add to the covenants of the Issuer or any Subsidiary Guarantor, to cure any ambiguity or omission or to correct any defect or inconsistency, to permit the qualification of the Indenture under the TIA, to add or release Subsidiary Guarantors pursuant to the terms of the Indenture, to make any change that does not adversely affect the rights under the Indenture of any Holder of the Notes, to add to, change or eliminate any of the provisions of the Indenture in respect of one or more series of Debt Securities in certain circumstances, to evidence or provide for the acceptance of appointment under the Indenture of a successor or separate Trustee or to establish the form or terms of any other series of Debt Securities.

Subject to certain limitations, Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its exercise of any trust or power. 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 the Trustee determines in good faith that withholding notice is in the Holders’ interests. The Holders of not less than 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 Default or Event of Default in the payment of interest on, the principal of, or premium, if any, on, the Notes or an Event of Default relating to a provision of the Indenture that cannot be amended without the consent of each Holder affected thereby.
