Item 14.  Indemnification of Directors and Officers.

   The section of the prospectus entitled "The Partnership
Agreement--Indemnification" discloses that we will generally indemnify
officers, directors and affiliates of the general partner to the fullest extent
permitted by the law against all losses, claims, damages or similar events and
is incorporated herein by this reference. Reference is also made to Section 8
of the Underwriting Agreement to be filed as an exhibit to this registration
statement in which Sunoco, Inc. and its affiliates will agree to indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended, and to contribute to payments that may be
required to be made in respect of these liabilities. Subject to any terms,
conditions or restrictions set forth in the partnership agreement, Section
17-108 of the Delaware Revised Uniform Limited Partnership Act empowers a
Delaware limited partnership to indemnify and hold harmless any partner or
other persons from and against all claims and demands whatsoever.


Item 15.  Recent Sales of Unregistered Securities.

   On October 15, 2001, in connection with the formation of the partnership,
Sunoco Logistics Partners L.P. issued to (i) Sunoco Partners LLC the 2% general
partner interest in the partnership for $20 and (ii) to Sun Pipe Line Company
of Delaware the 98% limited partner interest in the partnership for $980 in an
offering exempt from registration under Section 4(2) of the Securities Act.
There have been no other sales of unregistered securities within the past three
years. Concurrently with the issuance and distribution of the securities
registered hereby, Sunoco Logistics Partners Operations L.P., our operating
partnership, intends to issue $250 million of senior notes in an offering
exempt from registration under Section 4(2) of the Securities Act.

Item 17.  Undertakings

   The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

   Insofar as indemnification for liabilities arising under the Securities Act
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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for

                                     II-2


<PAGE>

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
Securities Act and will be governed by the final adjudication of such issue.

   The undersigned registrant hereby undertakes that:

      (1) For purposes of determining any liability under the Securities Act,
   the information omitted from the form of prospectus filed as part of this
   registration statement in reliance upon Rule 430A and contained in a 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.

      (2) For the purpose of determining any liability under the Securities
   Act, 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.

                                     II-3

                                  SIGNATURES

333-71968) to be signed on its behalf by the undersigned, thereunto duly

          representative samples of each new use and an accurate, written
          description for each new use that Licensees propose. Any new uses of

          advertising, promotional or display materials and sales documents
          bearing or using the Marks, all of which shall comply with the
          requirements set forth herein; and

          therefor any usage of the Marks on goods or services shall fail to

          necessary measures to improve such usage, as applicable, to meet such
          standards.

          (d) In order to confirm that Licensees' use of the Marks complies with
this Section 3.2, Licensors shall have the right, in their sole discretion, (i)

Licensees, or be construed to create, in any way, any guarantee or warranty on
the part of Licensors as to the fitness, quality, workmanship, or character of
the goods and services of Licensees or to authorize any liability for
indebtedness or claims of damage, whatsoever by any third party against
Licensors, or to impose any obligation on Licensors to purchase any of the goods
