          --------------------------------------------------------
Notwithstanding anything to the contrary contained in this Agreement including,
without limitation, the terms and provisions of this Article III, none of the
parties to this Agreement shall be deemed to have assumed, and none of the
Assets have been or are being contributed subject to, (i) any liens or security
interests securing consensual indebtedness covering any of the Assets, except to
the extent set forth on a schedule to this Agreement, and all such liens and
security interests shall be deemed to be excluded from the assumptions of
liabilities made under this Article III or (ii) any of the liabilities covered
by the indemnities set forth in the Omnibus Agreement to the extent such
liabilities are covered by such indemnities, and all such liabilities shall be
deemed to be excluded from the assumptions of liabilities made under this
Article III to the extent that such liabilities are covered by such indemnities.

                                   ARTICLE IV

          (a) Sunoco GP shall indemnify, defend and hold harmless the MLP, its
partners, its Affiliates and their respective members, directors, officers,
employees and their respective successors and assigns from and against any and

(including, without limitation, Pipeline LP) is not just and reasonable,
provided that the tariff rate found to be just and reasonable by the FERC is
less than (except for increases permitted under the FERC's indexed rate
methodology) the applicable tariff rate published by Sunoco or its applicable
Affiliates in effect at the Effective Time and which relates to the same
movement of crude oil or refined products. Notwithstanding the foregoing, the
total amounts required to be paid by Sunoco GP under this Section 4.1 shall not
exceed the difference between (i) the amount that the MLP and any of its
Affiliates may lawfully collect from Sunoco or any of its Affiliates pursuant to
any such decision of the FERC and (ii) the amount that, absent such a decision,
would have been collected from Sunoco or any of its Affiliates at the applicable
tariff rate published by Sunoco or its applicable Affiliates in effect at the
Effective Time (except for increases permitted under the FERC's indexed rate
methodology). In the event that Sunoco GP is required to make any payments under
this Section 4.1, such payment shall be made to the MLP or the applicable
Affiliate promptly after Sunoco GP has been notified by the MLP of such
determination by FERC.

          (b) The obligation of Sunoco GP to make the payments required to be
made under the terms of Section 4.1(a) is guaranteed by Sunoco in the Omnibus

certain fixtures, equipment and other personal property which are listed on the
applicable schedules to this Agreement, and (ii) any other fixtures, equipment
and other personal property located on the Real Property which are necessary for
the operation of the property listed in clause (i) of this sentence (the
property described in clauses (i) and (ii) of this sentence being called the
"Conveyed Assets") have been conveyed and transferred by operation of law or
----------------
otherwise to the applicable entity, as set forth in this Agreement. Each of the
parties owning any portion of the Real Property immediately prior to the
applicable transfer (by operation of law or otherwise) under this Agreement
intended to and has pursuant to this Agreement reserved unto itself and its
successors and assigns, respectively, any fixtures, equipment, and other
personal property owned by such parties immediately prior to the Effective Time
and located on the Real Property, except for the Conveyed Assets (the "Reserved
                                                                       --------
Assets").
------

          (b) All parties to this Agreement acknowledge and agree that the
applicable owners of the Reserved Assets will require reasonable access to the
Reserved Assets in connection with the operation, maintenance, repair, removal
and replacement of the Reserved Assets, and in order to facilitate such access,
each of the applicable owners of the Reserved Assets intended to reserve and
has, by the execution of this Agreement, reserved unto itself, for itself and
its respective successors and assigns, the right to reasonable access to the
Reserved

                                       38

<PAGE>

Assets over, across and under the Real Property for the operation, maintenance,
repair, removal and replacement of the Reserved Assets provided that such access
does not unreasonably interfere with the use of the Conveyed Assets by the
applicable owner thereof.

          (c) The parties to this Agreement further acknowledge and agree that
in order to give proper notice to third parties or to comply with applicable
law, it may be necessary to record certain documents in order to evidence the
rights of the applicable owners of the Reserved Assets, and the parties to this
Agreement agree to execute and cause to be recorded all such documents as may be
required.

                                   ARTICLE VI
                               Further Assurances

     6.1 Further Assurances. From time to time after the date hereof, and
         ------------------
without any further consideration, the parties to this Agreement agree to
execute, acknowledge and deliver all such additional deeds, assignments, bills
of sale, conveyances, instruments, notices, releases, acquittances and other
documents, and will do all such other acts and things, all in accordance with
applicable law, as may be necessary or appropriate (i) more fully to assure that
the applicable parties to this Agreement own all of the properties, rights,
titles, interests, estates, remedies, powers and privileges granted by this
Agreement, or which are intended to be so granted (ii) more fully and
effectively to vest in the applicable parties to this Agreement and their
respective successors and assigns beneficial and record title to the interests
contributed and assigned by this Agreement or intended so to be and to more
fully and effectively carry out the purposes and intent of this Agreement.

     6.2 Other Assurances. From time to time after the date hereof, and without
         ----------------
any further consideration, each of the parties to this Agreement shall execute,
acknowledge and deliver all such additional instruments, notices and other
documents, and will do all such other acts and things, all in accordance with
applicable law, as may be necessary or appropriate to more fully and effectively
carry out the purposes and intent of this Agreement. Without limiting the
generality of the foregoing, the parties to this Agreement acknowledge that the
parties have used their good faith efforts to attempt to identify all of the
assets being contributed to the MLP or its subsidiaries as required in
connection with the Offering. However, due to the age of some of those assets
and the difficulties in locating appropriate data with respect to some of the
assets it is possible that assets intended to be contributed to the MLP or its
subsidiaries were not identified and therefore are not included in the assets
contributed to the MLP or its subsidiaries. It is the express intent of the
parties to this Agreement that the MLP or its subsidiaries own all assets
necessary to operate the assets that are identified in this Agreement and in the
Registration Statement. To the extent any assets were not identified but are
necessary to the operation of assets that were identified, then the intent of
the parties to this Agreement is that all such unidentified assets are intended
to be conveyed to the appropriate members of the Partnership Group. To the
extent such assets are identified at a later date, the parties to this Agreement
shall take the appropriate actions required in order to convey all such assets
to the appropriate members of the Partnership Group. Likewise, to the extent
that assets are identified at a later date that were not intended by the parties
to be conveyed as reflected in the Registration Statement, the parties to this
Agreement shall take the appropriate actions required in order to convey all
such assets to the appropriate party.

<PAGE>

written consent of third parties, including, without limitation, governmental
agencies (other than consents of a ministerial nature which are normally granted
in the ordinary course of business), which if not satisfied would result in a
breach of such prohibitions or conditions or would give an outside party the
right to terminate rights of the party to whom the applicable Assets were
intended to be conveyed (the "Beneficial Owner") with respect to such portion of
                              ----------------
