ITEM 15. Indemnification of Directors and Officers

ONEOK, Inc., as an Oklahoma corporation (“ONEOK”), is empowered by Section 1031 of the Oklahoma General Corporation Act, subject to the procedures and limitations stated therein, to indemnify any person against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any threatened, pending or completed action, suit or proceeding (whether civil, criminal, administrative or investigative) in which such person is made or threatened to be made a party by reason of his being or having been a director, officer, employee or agent of ONEOK or is or was serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of ONEOK, and with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. However, in an action by or in the right of ONEOK, Section 1031 prohibits indemnification if such person is adjudged to be liable to ONEOK, unless such indemnification is allowed by a court of competent jurisdiction. The statute provides that indemnification pursuant to its provisions is not exclusive of other rights of indemnification to which a person may be entitled under any bylaw, agreement, vote of shareholders, or disinterested directors, or otherwise.

The certificate of incorporation of ONEOK provides that a director of the corporation shall not be personally liable to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except for liability for (i) any breach of the director’s duty of loyalty to the corporation or its shareholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) payment of unlawful dividends or unlawful stock purchases or redemptions or (iv) any transaction from which the director derived an improper personal benefit.

II-1

Article VIII of ONEOK’s bylaws provides that directors and officers of ONEOK shall be indemnified by ONEOK to the fullest extent permitted by the Oklahoma General Corporation Act, including the advance of related expenses. Pursuant to Article VIII of the bylaws of ONEOK, upon authorization and determination (i) by the board of directors by a majority vote of the directors who were not parties to such action, suit or proceeding, even though less than a quorum; (ii) by a committee of directors designated by a majority vote of directors, even though less than a quorum; (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion; or (iv) by the shareholders, ONEOK is obligated to indemnify any person who incurs liability by reason of the fact that he is or was a director, officer, employee or agent of ONEOK, or is or was serving at the request of ONEOK as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise or as a member of any committee or similar body, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of ONEOK, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. However, in an action, suit or proceeding by or in the right of ONEOK, no indemnification will be made if such person shall be adjudged to be liable to ONEOK, unless such indemnification is allowed by a court of competent jurisdiction.

ONEOK has entered into indemnification agreements with its directors and officers. These indemnification agreements provide that ONEOK is obligated to indemnify the specified director or officer to the fullest extent permitted by law. The agreements provide that, upon request by a director or officer, ONEOK is obligated to advance expenses for defense of a claim made against the director or officer. The obligation of ONEOK to indemnify the director or officer is subject to applicable law and the determination by a “reviewing party” selected by the board of directors that the director or officer is entitled to indemnification. In addition, the agreements obligate ONEOK to indemnify the specified officer or director to the extent of ONEOK’s recoveries under insurance policies regardless of whether the director or officer is ultimately determined to be entitled to indemnification. The agreements also provide for partial indemnification if a portion of a claim for indemnification is not allowed by the reviewing party appointed by the board of directors.

ONEOK provides liability insurance for its directors and officers which provides for coverage against loss from claims made against officers and directors in their capacity as such, including, subject to certain exceptions, liabilities under the federal securities laws.

It is recognized that the above-summarized provisions of ONEOK’s bylaws, the indemnification agreements and the applicable provisions of the Oklahoma General Corporation Act may be sufficiently broad to indemnify officers, directors and controlling persons of ONEOK against liabilities arising under such act.

Delaware Limited Partnership Registrants

Section 17-108 of the Delaware Revised Limited Partnership Act empowers a Delaware limited partnership to indemnify and hold harmless any partner or other person from and against all claims and demands whatsoever.

Section 6.7 of the limited partnership agreements of ONEOK Partners, L.P. (“ONEOK Partners”) and ONEOK Partners Intermediate Limited Partnership (“ONEOK ILP”) provides that the applicable partnership will indemnify and hold harmless any Indemnitee (as defined below) from any and all losses, claims, damages, liabilities (joint or several), expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as (i) a general partner, a member of the applicable partnerships board of directors or any committee thereof, a former member of the applicable partnership’s policy committee, a departing general partner, or any of their affiliates, (ii) a member, partner, director, officer (including an authorized officer), employee, agent, fiduciary or trustee of any group member, any general partner or any departing general partner or any of their respective affiliates, or (iii) a person serving at the request of the applicable partnership in another entity in a similar capacity, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the partnership, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

II-2

“Indemnitee” means, with respect to ONEOK Partners, any (i) general partner, (ii) any member of the board of directors or any committee thereof (including the audit committee or the conflicts committee), (iii) any departing general partner, (iv) any person who is or was a member, partner, director, officer (including an authorized officer), employee, agent, fiduciary or trustee of any group member, any general partner or any departing general partner or any of their respective affiliates, (v) any person who is or was serving at the request of any general partner, the general partner, the partnership policy committee, the board of directors or any departing general partner as an officer, director, member, partner, fiduciary or trustee of another person or as a member of any committee appointed by the partnership, the general partner, the partnership policy committee or the board of directors or pursuant to the applicable requirements of the commission, any national securities exchange on which partnership securities are listed or admitted to trading; provided that a person is not an Indemnitee by reason of providing, on a fee-for-services basis, trustee, fiduciary or custodial services, (vi) any former member of the partnership policy committee or of any committee of the partnership established by the partnership policy committee (including, without limitation, the members of the audit committee), and (vii) any person the general partner designates as an “Indemnitee.”

“Indemnitee” means, with respect to ONEOK ILP, any general partner, any member of the board of directors or any committee thereof (including, without limitation, the audit committee), any departing partner, any person who is or was an affiliate of any general partner or any departing partner, any person who is or was an officer, director, employee, partner, agent or trustee of any general partner, the partnership or any departing partner or any such affiliate, any representative of the partnership on the NBPL Management Committee, or any person who is or was serving or any such affiliate as a director, officer, employee, partner, agent or trustee of another person.

Any indemnity claim made pursuant to Section 6.7 will be paid out of the assets of the applicable partnership and not from assets held by its general partner. Each of ONEOK Partners and ONEOK ILP have entered into separate indemnification agreements with its general partner.

ITEM 17. Undertakings

Each of the undersigned co-registrants hereby undertakes:

(a) (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii)

to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii)

to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

II-10

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by such undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(d) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act.
