                               Further Assurances

     6.1  Further Assurances. From time to time after the date hereof, and
          ------------------
without any further consideration, Services LP and R&M shall 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 Services Out
LLC and R&M In LP, respectively, their successors and assigns, ownership of all
of the properties, rights, titles, interests, estates, remedies, powers and
privileges by this Agreement granted to Services Out LLC and R&M In LP with
respect to the Services Out LLC Assets and the R&M In LP Assets, respectively,
or which are intended to be so granted (ii) more fully and effectively to vest
in Services Out LLC and R&M In LP and their respective successors and assigns
beneficial and record title to the interests hereby contributed and assigned to
Services Out LLC and R&M In LP 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

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 Partnership
Entities. 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 Partnership Entities.

                                  Miscellaneous

     8.1  Order of Completion of Transactions. The transactions provided for in
          -----------------------------------
Articles II and III of this Agreement shall be completed on the date of this
Agreement in the following order:

          First, the transactions provided for in Article II shall be completed;
          -----
and

          Second, the transactions provided for in Article III shall be
          ------
completed.

     8.2  Consents; Restriction on Assignment. If there are prohibitions against
          -----------------------------------
or conditions to the contribution and conveyance of one or more portions of the
Services Out LLC Assets or the R&M In LP Assets without the prior 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 Services Out LLC's or R&M In LLC's rights with respect to such portion
of the Services Out LLC Assets or R&M In LP Assets, respectively (herein called
a "Restriction"), then any provision contained in this Agreement to the contrary
   -----------
notwithstanding, the transfer of title to or interest in each such portion of
the Services Out LLC Assets or R&M In LP Assets (herein called the
"Restriction-Asset") pursuant to this Agreement shall not become effective
 -----------------
unless and until such Restriction is satisfied, waived or no longer applies.
When and if such a Restriction is so satisfied, waived or no longer applies, to
the extent permitted by applicable law and any applicable contractual
provisions, the assignment of the Restriction-Asset subject thereto shall become
effective automatically as of the Effective Time, without further action on the
part of any party to this Agreement. Services LP and Services Out LLC agree to
use their reasonable best efforts to obtain on a timely basis satisfaction of
any Restriction applicable to any Restriction-Asset conveyed by or acquired by
either of them. [R&M and R&M In LP agree to use their reasonable best efforts to
obtain on a timely basis satisfaction of any Restriction applicable to any
Restriction Asset conveyed by or acquired by either of them.] The description of
any portion of the Services Out LLC Assets or R&M In LP Assets as a
"Restriction-Asset" shall not be construed as an admission that any Restriction
exists with respect to the transfer of such portion of the Services Out LLC
Assets or R&M In LP Assets. In the event that any Restriction-Asset exists, the
applicable party agrees to continue to hold such Restriction-Asset in trust for
the exclusive benefit of the applicable party to whom such asset was conveyed
and to otherwise use its reasonable best efforts to provide such other party
with the benefits thereof, and the party holding such assets will enter into
other agreements, or take such other action as it may deem necessary, in order
to help ensure that the applicable party to whom such asset was conveyed has the
assets and concomitant rights necessary to enable it to operate the such assets
in all material respects as they were operated prior to the Effective Time.

     8.3  Costs. The OLP shall pay all sales, use and similar taxes arising out
          -----
of the contributions, conveyances and deliveries to be made hereunder, and shall
pay all documentary, filing, recording, transfer, deed, and conveyance taxes and
fees required in connection therewith. In addition, the OLP shall be responsible
for all costs, liabilities and expenses (including court

satisfaction or waiver of any Restriction pursuant to Section 8.2.

     8.4  Headings; References; Interpretation. All Article and Section headings
          ------------------------------------

affect the meaning or construction of any of the provisions hereof. The words

unless the context requires a different construction, be deemed to be references
to the Articles, Sections and Exhibits of this Agreement, respectively, and all
such Exhibits attached hereto are hereby incorporated herein and made a part
hereof for all purposes. All personal pronouns used in this Agreement, whether
used in the masculine, feminine or neuter gender, shall include all other
genders, and the singular shall include the plural and vice versa. The use
herein of the word "including" following any general statement, term or matter
shall not be construed to limit such statement, term or matter to the specific
items or matters set forth immediately following such word or to similar items
or matters, whether or not non-limiting language (such as "without limitation,"
"but not limited to," or words of similar import) is used with reference
thereto, but rather shall be deemed to refer to all other items or matters that
could reasonably fall within the broadest possible scope of such general
statement, term or matter.

     8.5  Successors and Assigns. The Agreement shall be binding upon and inure
          ----------------------
to the benefit of the parties signatory hereto and their respective successors
and assigns.

     8.6  No Third Party Rights. The provisions of this Agreement are intended
          ---------------------

the parties hereto.

     8.8  Governing Law. This Agreement shall be governed by, and construed in
          -------------
accordance with, the laws of the State of [ ] applicable to contracts made and
to be performed wholly within such state without giving effect to conflict of
law principles thereof, except to the extent that it is mandatory that the law
of some other jurisdiction, wherein the Services Out LLC Assets or the R&M In LP
Assets are located, shall apply.

     8.9  Severability. If any of the provisions of this Agreement are held by
          ------------
any court of competent jurisdiction to contravene, or to be invalid under, the
laws of any political body having jurisdiction over the subject matter hereof,
such contravention or invalidity shall not invalidate the entire Agreement.
Instead, this Agreement shall be construed as if it did not contain the
particular provision or provisions held to be invalid, and an equitable
adjustment shall be made and necessary provision added so as to give effect to
the intention of the parties as expressed in this Agreement at the time of
execution of this Agreement.
