The Notes shall be executed, authenticated and delivered in accordance with the provisions of, and shall in all respects be subject to, the terms, conditions and covenants of the Original Indenture as supplemented by this Supplemental Indenture (including the form of Note set forth as Exhibit A hereto (the terms of which are incorporated in and made a part of this Supplemental Indenture for all intents and purposes)).

Following the receipt by the Trustee of any such notice, the Partnership shall cause this Indenture to be amended as provided in Section 9.01(l) hereof; provided, however, that the failure to so amend this Indenture shall not affect the validity of the termination of the Guarantee with respect to such Guarantor.”

ONEOK PARTNERS, L.P., a Delaware limited partnership (herein called the “Partnership”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to , or registered assigns, the principal sum of United States Dollars ($ ) on February 1, 2041, and to pay interest thereon from January 26, 2011, or from the most recent interest payment date to which interest has been paid or duly provided for, semi-annually on February 1 and August 1 in each year, commencing on August 1, 2011, at the rate of 6.125% per annum, until the principal hereof is paid or made available for payment and at the same rate per annum on any overdue principal and premium and on any overdue installment of interest. The amount of interest payable for any period shall be computed on the basis of twelve 30-day months and a 360-day year. The amount of interest payable for any partial period shall be computed on the basis of a 360-day year of twelve 30-day months and the days elapsed in any partial month. In the event that any date on which interest is payable on this Note is not a Business Day, then a payment of the interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable.

[REVERSE OF NOTE]

ONEOK PARTNERS, L.P.

6.125% Senior Note due 2041

This security is one of a duly authorized issue of debt securities of the Partnership (the “Debt Securities”), issued and to be issued in one or more series under an Indenture dated as of September 25, 2006, as amended and supplemented to date, including without limitation by the Seventh Supplemental Indenture thereto, dated as of January 26, 2011 (such Indenture, as so amended and supplemented being referred to herein as the “Indenture”), between the Partnership and Xxxxx Fargo Bank, N.A., as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Partnership, the Trustee and the Holders of the Debt Securities and of the terms upon which the Debt Securities are, and are to be, authenticated and delivered. This Debt Security is one of the series designated on the face hereof. The Debt Securities of this series are referred to herein as the “Notes.”

On or after August 1, 2040 (six months prior to the maturity date of the Notes), the Notes will be subject to redemption at any time at the option of the Partnership, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus any accrued and unpaid interest thereon to the applicable Redemption Date (subject to the right of holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date).

Prior to August 1, 2040, the Notes will be subject to redemption at any time at the option of the Partnership, in whole or in part, at a redemption price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments (excluding accrued interest) discounted to the applicable Redemption Date, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Comparable Treasury Yield (as defined below), plus 25 basis points, plus, in each case, any accrued and unpaid interest thereon to the applicable Redemption Date (subject to the right of holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to such Redemption Date).

The present values of the remaining scheduled payments referred to in clause (ii) of the immediately preceding paragraph (the “present values”) will be determined in accordance with generally accepted principles of financial analysis. These present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for the redemption, to the Redemption Date at a discount rate equal to the Comparable Treasury Yield plus 25 basis points. The present values will be calculated by an independent investment banking institution of national standing appointed by the Partnership. If the Partnership fails to appoint an independent investment banker not less than 30 days prior to the Redemption Date, or if such independent investment banker is unwilling or unable to make the calculation, the calculation will be made by Citigroup Global Markets Inc., RBS Securities Inc. and UBS Securities LLC. If Citigroup Global Markets Inc., RBS Securities Inc. and UBS Securities LLC are unwilling or unable to make the calculation, the Partnership will appoint an independent investment banking institution of national standing to make the calculation.

For purposes of determining the present values, “Comparable Treasury Yield” means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Securities that have a constant maturity that corresponds to the remaining term to maturity of the Notes, calculated to the nearest 1/12th of a year. The Comparable Treasury Yield will be determined as of the third business day immediately preceding the applicable Redemption Date, and prior to the Redemption Date the Partnership shall deliver to the Trustee an Officers’ Certificate setting forth the redemption price and showing the calculation thereof in reasonable detail.

The weekly average yields of United States Treasury securities will be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated “H.15(519) Selected Interest Rates” or any successor release. If the H.15 statistical release sets forth a weekly average yield for United States Treasury securities having a constant maturity that is the same as the remaining term calculated as set forth above, then the Comparable Treasury Yield will be equal to such weekly average yield. In all other cases, the Comparable Treasury Yield will be calculated by interpolation on a straight-line basis between the weekly average yields on the United States Treasury securities that have a constant maturity closest to and greater than the remaining term and the United States Treasury securities that have a constant maturity closest to and less than the

A-4

remaining term (in each case as set forth in the H.15 statistical release or any successor release). Any weekly average yields calculated by interpolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200th of 1% or above being rounded upward. If weekly average yields for United States Treasury securities are not available in the H.15 statistical release or otherwise, then the Comparable Treasury Yield will be calculated by interpolation of comparable rates selected by an independent investment banking institution of national standing selected in the manner described in the second preceding paragraph.

Unless the Partnership defaults in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on this Note or the portions hereof called for redemption.

In the event of redemption of this Note in part only, a new Note or Notes of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture contains provisions for defeasance at any time of (1) the entire indebtedness of this Note or (2) certain restrictive covenants and Events of Default with respect to this Note, in each case upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Partnership, the Guarantor and the rights of the Holders of the Debt Securities of each series to be affected under the Indenture at any time by the Partnership, the Guarantor and the Trustee with the consent of not less than the Holders of a majority in principal amount of the Outstanding Debt Securities of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Outstanding Debt Securities of each affected series, on behalf of the Holders of all Debt Securities of such series, to waive compliance by the Partnership and the Guarantor with certain provisions of the Indenture. The Indenture permits, with certain exceptions as therein provided, the Holders of a majority in principal amount of Debt Securities of any series then Outstanding to waive past defaults under the Indenture with respect to such series and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and all holders of Notes of which this Note is a predecessor Note, whether or not notation of such consent or waiver is made upon this or any other Note.

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any action or proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of not less than 25% in aggregate principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default and offered the Trustee reasonable indemnity or security as required by the Trustee and the Trustee shall not have received from the Holders of a majority in principal amount of Notes at the time Outstanding a direction inconsistent with such request, and the Trustee shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity or security. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Partnership, which is absolute and unconditional, to pay the principal of and any premium and interest on this Note at the times, place(s) and rate, and in the currency, herein prescribed.

[If a Global Security, insert—This Global Security or portion hereof may not be exchanged for definitive Debt Securities of this series except in the limited circumstances provided in the Indenture.

The holders of beneficial interests in this Global Security will not be entitled to receive physical delivery of definitive Debt Securities except as described in the Indenture and will not be considered the Holders thereof for any purpose under the Indenture.]

[If a definitive Debt Security, insert—As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registerable in the Debt Security Register, upon surrender of this Note for

A-5

registration of transfer at the office or agency of the Partnership in The City of New York, or, subject to any laws or regulations applicable thereto and to the right of the Partnership (limited as provided in the Indenture) to rescind the designation of any such transfer agent, at the offices of in the Borough of Manhattan, The City of New York, and at such other offices or agencies as the Partnership may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Partnership and the Debt Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.]

The Notes are issuable only in registered form without coupons in denominations of $2,000 and any whole multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Partnership may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Note for registration of transfer, the Partnership, the Guarantor, the Trustee and any agent of the Partnership, the Guarantor or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Partnership, the Guarantor, the Trustee nor any such agent shall be affected by notice to the contrary.

Obligations of the Partnership and the Guarantor under the Indenture and the Debt Securities thereunder, including this Note, are non-recourse to ONEOK Partners GP, L.L.C. (the “General Partner”) and ONEOK ILP GP, L.L.C. (the “Guarantor General Partner”) and their respective Affiliates (other than the Partnership and the Guarantor), and payable only out of cash flow and assets of the Partnership and the Guarantor. The Trustee, and each Holder of a Debt Security by its acceptance thereof, will be deemed to have agreed in the Indenture that (1) none of the General Partner, the Guarantor General Partner and their respective assets (nor any of their respective Affiliates, other than the Partnership and the Guarantor, or their respective assets) shall be liable for any of the obligations of the Partnership or the Guarantor under the Indenture or such Debt Securities, including this Note, and (2) no director, officer, employee, stockholder or unitholder, as such, of the Partnership, the Guarantor, the Trustee, the General Partner, the Guarantor General Partner or any Affiliate of any of the foregoing entities shall have any personal liability in respect of the obligations of the Partnership or the Guarantor under the Indenture or such Debt Securities by reason of his, her or its status.

This Note shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
