will not be unreasonably delayed or withheld. The foregoing does not apply to
Operator’s assignment of this Agreement to TransMontaigne Partners L.P.

9.5   Applicable Law.  This Agreement shall be governed by the laws of the State
of Texas.

9.6   Limitation of Damages.  Neither Party shall be liable for prospective
profits or special, punitive, indirect or consequential losses or damages of any
kind arising out of or in any way connected with the performance of or failure
to perform this Agreement, including, but not limited to losses or damages
resulting from shutdown of plants or inability to perform sales or any other
contracts arising out of or in connection with the performance or
non-performance of this Agreement.

9.7   Access.  Rio and its designees shall have full and complete access at all
times to the U.S. Pipeline and all records and documents associated therewith
prepared and maintained by the Operator.

9.8   Force Majeure.

(A)   Except for Rio’s obligation to make proper payment to the Operator under
this Agreement, in the event either Rio or Operator is rendered unable, by
reason of an event of force majeure, to perform, wholly or in part, any
obligation or commitment set forth in this Agreement, then upon such party
giving notice and full particulars (including all supporting documentation) of
such event as soon as practicable after the occurrence thereof, the obligations
of both parties shall be suspended to the extent and for the period of such
force majeure provided that the party claiming an event of force majeure shall
make all reasonable attempts to remedy the same with all reasonable dispatch.

(B)   Neither Party shall be entitled to the benefit of the provisions of this
Section under either or both of the following circumstances:
 

--------------------------------------------------------------------------------

 
(1)    To the extent that the failure was caused by the Party claiming
suspension having failed to remedy the condition by taking all reasonable acts,
short of litigation, if such remedy requires litigation, and having failed to
resume performance of such commitments or obligations with reasonable dispatch;
or,

(2)    If the failure was caused by lack of funds, or with respect to the
payment of any amount or amounts then due hereunder.

(C)   Settlement of strikes and lockouts shall be entirely within the discretion
of the party affected, and the duty that any event of force majeure shall be
remedied with all reasonable dispatch shall not require the settlement of
strikes and lockouts by acceding to the demands of the parties directly or
indirectly involved in such strikes or lockouts when such course is inadvisable
in the discretion of the Party having such difficulty.

9.9   Notices.  Except as may be otherwise provided in this Agreement, all
notices to be given hereunder shall be in writing and delivered by (i) confirmed

purposes of this Agreement, the singular number includes the plural number and

--------------------------------------------------------------------------------

9.11    Press Releases.  There shall be no press releases, press statements, or
other announcements or statements by Operator concerning or relating to this

information associated with the operation or maintenance of the U.S. Pipeline

9.12     Liens.  Operator shall keep the U.S. Pipeline free of any and all
liens, encumbrances and claims at all times.

9.13    Direction of Employees.  Rio shall not have power or authority to

in the exercise of their independent employment, select the means, manner and
method of performance of the services to be provided under this Agreement.

9.14     Counterpart.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
constitute but one and the same document.

9.15     Alternative Dispute Resolution.
 
(A)   Covered Disputes.  Any dispute, controversy or claim (whether sounding in
contract, tort or otherwise) arising out of or relating to this Agreement,
including without limitation the meaning of its provisions, or the proper
performance of any of its terms by either Party, its breach, termination or
invalidity (“Dispute”) will be resolved in accordance with the procedures
specified in this paragraph, which will be the sole and exclusive procedure for
the resolution of any such Dispute, except that a Party, without prejudice to
the following procedures, may file a complaint to seek preliminary injunctive or
other provisional judicial relief, if in its sole judgment, that action is
necessary to avoid irreparable damage or to preserve the status quo. Despite
that action the Parties will continue, subject to subsection (F) hereinbelow, to
participate in good faith in the procedures specified in this Section.

(B)    Initiation of Procedures.  Either Party wishing to initiate the dispute
resolution procedures set forth in this paragraph with respect to a Dispute not
resolved in the ordinary course of business must give written notice of the
Dispute to the other Party (“Dispute Notice”). The Dispute Notice will include
(i) a statement of that Party’s position and a summary of arguments supporting
that position, and (ii) the name and title of the executive who will represent
that Party, and of any other person who will accompany the executive, in the
negotiations under the next subsection.

(C)    Negotiation Between Executives.  If one Party has given a Dispute Notice
under the preceding subparagraph, the Parties will attempt in good faith to
resolve the Dispute within 45 calendar days of the notice by negotiation between
executives who have authority to settle the Dispute and who are at a higher
level of management than the persons with direct responsibility for
administration of this Agreement or the matter in Dispute. Within 15 calendar
days after delivery of the Dispute Notice, the receiving Party will submit to
the other a written response. The response will include (i) a statement of that
Party's position and a summary of arguments supporting that position, and (ii)
the name and title of the executive who will represent that Party and of any
other person who will accompany the executive. Within 45 calendar days after
delivery of the Dispute Notice, the executives of both Parties will meet at a
mutually acceptable time and place, and thereafter, as often as they reasonably
deem necessary, to attempt to resolve the Dispute.

--------------------------------------------------------------------------------

(D)   Mediation.  If the Dispute has not been resolved by negotiation under the
preceding subsection within 45 calendar days of the Dispute Notice, and only in
such event, either Party may initiate the mediation procedure of this subsection
by giving written notice to the other Party (“Mediation Notice”). The Parties
will endeavor to settle the Dispute by mediation within 90 calendar days of the
Mediation Notice under the then current Center for Public Resources ("CPR")
Model Mediation Procedure for Business Disputes. If the Parties have not agreed
upon a mediator within seven calendar days after the Mediation Notice, either
Party may request CPR assistance in the selection of a mediator under its
guidelines. The mediator will establish rules for an expedited discovery
procedure and will resolve all disputes with regard to discovery between the
Parties. If the mediator has not already done so during the mediation process,
at least seven calendar days before the end of the ninety day mediation period,
the mediator, if he or she believes that they are qualified to do so, will
provide to each Party a written summary of the mediator's conclusions regarding
the outcome of the Dispute if it is submitted to arbitration under the following
subsection.

(E)    Arbitration.  If the Dispute has not been resolved by mediation under the
preceding subsection within 90 calendar days of the Mediation Notice, and only
in such event, either Party may initiate the arbitration procedure of this
subsection by giving written notice to the other Party (“Arbitration Notice”).
The Dispute will be finally resolved by binding arbitration in accordance with
the then current Arbitration Rules of the American Arbitration Association
(“AAA”) by a single arbitrator, chosen by mutual agreement of both Parties. If
the Parties cannot select an arbitrator within 30 calendar days of the
Arbitration Notice, the arbitrator will be selected by the AAA. The arbitration
will be governed by the United States Arbitration Act, 9 U.S.C. Sec. 1-16, as
amended (“the Act”), and to the extent not inconsistent with the Act, the Texas
arbitration statute. Judgment upon the award rendered by the arbitrator may be
entered by any court of any state having jurisdiction. The statute of
limitations of the State of Texas for the commencement of a lawsuit will apply
to the commencement of an arbitration under this Agreement, except that no
defenses will be available based upon the passage of time during any negotiation
or mediation called for by this Section. Each Party will assume its own costs of
legal representation and expert witnesses and the Parties will share equally the
other costs of the arbitration. The arbitrator will award pre-judgment interest
in accordance with the law of Texas; however, the arbitrator may not award
punitive damages. The arbitration will take place in Houston, Texas.

--------------------------------------------------------------------------------

(F)    Tolling and Performance.  Except as indicated in the preceding subsection
with regard to the commencement of arbitration, all applicable statutes of
limitation and defenses based upon the passage of time will be tolled while the
procedures specified in this paragraph are pending. The Parties will take any
action required to effectuate that tolling. Each Party is required to continue
to perform its obligations under this Agreement pending final resolution of any
Dispute, unless to do so would be impossible or impracticable under the
circumstances.”
