ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law ("DGCL") provides that
a corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding whether civil, criminal, administrative or investigative (other than
an action by or in the right of the corporation by reason of the fact that he is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Section 145 further
provides that a corporation similarly may indemnify any such person serving in
any such capacity who was or is a party or is threatened to be made a party to
any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees) actually and reasonably
incurred in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Delaware Court of Chancery or such other
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all of the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Delaware Court of Chancery or such other
court shall deem proper.

     The company's certificate of incorporation and bylaws provide that
indemnification shall be provided for all current and former directors and may
be provided for all current or former officers to the fullest extent permitted
by the DGCL.

     As permitted by the DGCL, the certificate of incorporation provides that
directors of the company shall have no personal liability to the company or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except (1) for any breach of the director's duty of loyalty to the company or
its stockholders,

                                      II-1
   3

(2) for acts or omissions not in good faith or which involve intentional
misconduct or knowing violation of law, (3) under Section 174 of the DGCL or (4)
for any transaction from which a director derived an improper personal benefit.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

     The company has not sold any securities, registered or otherwise, within
the past three years, except as set forth below.

     On December 8, 1999, the company issued 1,000 shares of its common stock to
Duke Energy Corporation ("Duke Energy") for $1,000. In so doing, the company
relied on the provisions of Section 4(2) of the Securities Act of 1933, as
amended (the "Securities Act"), in claiming exemption for the offering, sale and
delivery of such securities from registration under the Securities Act.

     On December 16, 1999, Duke Energy, Phillips Petroleum Company ("Phillips")
and Duke Energy Field Services, LLC ("Field Services LLC") entered into a
Contribution Agreement (the "Contribution Agreement") pursuant to which Duke
Energy and Phillips, on March   , 2000, contributed their respective midstream
natural gas assets to Field Services LLC, a subsidiary of the company, in
exchange for member interests in Field Services LLC and one-time cash payments.
Upon consummation of the offering contemplated by this registration statement,
the subsidiary ("Merger Subsidiary") that indirectly holds Phillips' interest in
Field Services LLC will be merged into the company, and, as a result, the
capital stock of Merger Subsidiary, all of which is owned by Phillips, will be
converted into shares of common stock of the company and the capital stock of
the company before the merger, all of which is owned by Duke Energy, will be
converted into new shares of common stock of the company. The exact allocation
between Duke Energy and Phillips of shares of common stock of the company issued
in the merger will be determined by the average of the closing prices of the
company's common stock on the New York Stock Exchange Composite Tape on the
stock's first five trading days. In so doing, the company relied on the
provisions of Section 4(2) of the Securities Act in claiming exemption for the
offering, sale and delivery of such securities from registration under the
Securities Act.

     (B) FINANCIAL STATEMENT SCHEDULE

     No financial statement schedules are required to be included herewith or
they have been omitted because the information required to be set forth therein
is not applicable.

ITEM 17. UNDERTAKINGS.

     The Registrant hereby undertakes:

          (a) 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 provisions described
     in Item 14, or otherwise, the Registrant has been advised that in the
     opinion of the Securities and Exchange Commission 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

                                      II-3
   5

     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.

          (b) To provide to the underwriter(s) at the closing specified in the
     underwriting agreements, certificates in such denominations and registered
     in such names as required by the underwriter(s) to permit prompt delivery
     to each purchaser.

          (c) For purpose of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1)
     or (4) or 497(h) under the Securities Act shall be deemed to be part of
     this Registration Statement as of the time it was declared effective.

          (d) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus 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.
