to the Contract or Amendments. Nothing in this confidentiality provision will

financing.

                                     Page 2
<PAGE>

Burlington Northern Santa Fe agrees to, either actively or constructively, place
loaded trains at CSI's designated unloading facility, at Kaiser, California, at
or prior to 9:00 A.M. of the morning subsequent to the release of trains at
origin. When train does not meet the above service commitment, CSI agrees to
notify Burlington Northern Santa Fe by fax @ 213-267-5668 within 12 hours of
train's actual arrival, indicating the actual time of arrival.

Burlington Northern Santa Fe guarantees that all trains shall meet the
applicable standard for rail transit time set forth above, during each Service
Period. A Service Period is defined as a period of one calendar month. The first
Service Period will commence on the first day of January, 1999. Each Service
Period will include all trains which were placed or released in interchange with
CSI during such Service Period.

If at the end of a Service Period, Burlington Northern Santa Fe fails to meet
this Service Guarantee on one or more trains, Burlington Northern Santa Fe will
pay CSI $597.00 per train, for each train Burlington Northern Santa Fe fails to
deliver at, or before 9:00 A.M. on any day. For CSI's convenience, Burlington
Northern Santa Fe will make every effort to place loaded trains at CSI's
unloading facility at Kaiser, California prior to 6:30 A.M.

The service commitment specified above shall not apply where Burlington Northern
Santa Fe is unable to perform due to an Act of God, strikes, lockouts, wrecks,
mechanical breakdowns in equipment of facilities of Burlington Northern Santa
Fe, CSI or its agent, or any act or failure on the part of CSI or its agent.

8. SERVICE COMMITMENT

If CSI or its agent meets its obligations in the next paragraph, Burlington
Northern Santa Fe agrees to place an empty train at CSI's designated loading
facility located at the Port of Long Beach or Los Angeles Harbor, California at
or prior to the time for which CSI or its agent had ordered placement.

CSI or its agent shall give Burlington Northern Santa Fe notice by a telephone
call at 213-267-4086, to place an empty train, or a portion thereof, at CSI's
designated loading facility at the Port of Long Beach or Los Angeles Harbor,
California no later than 22 hours before the time at which CSI or its agent
desires the train to be placed.

If Burlington Northern Santa Fe fails to meet the service commitment as above
stated for reasons other than those set forth in the next paragraph, Burlington
Northern Santa Fe agrees to pay CSI a sum not to exceed $900.00 per hour (CSI
will submit invoice furnished by their agent (RDP) outlining actual per hour
out-of-pocket cost but not to exceed $900.00 per hour) up to a maximum, of eight
(8) hours for each hour or portion thereof, that elapses between the time of
actual placement and the time for which placement was ordered. Notwithstanding
the foregoing if Burlington Northern Santa Fe is not able to furnish empty cars
for the 8:00 A.M. or 1:00 P.M. loading shift but telephones CSI's agent (RDP)
not later than 7:00 A.M. of the same day; Burlington Northern Santa Fe agrees to
pay CSI a sum not to exceed $900.00 per hour (CSI will submit invoice furnished
by their agent (RDP) outlining actual per hour out-of-pocket costs but not to
exceed $900.00 per hour) for a total of (4) hours in lieu of (8) hours as
provided above. Provided however that Burlington Northern Santa Fe shall not be
obligated to make such payment unless CSI or its agent has given Burlington
Northern Santa Fe notice of CSI's intent to invoke this Section, within the
first two (2) hours of such delay, by telephone call at 213-267-4086 and has
followed such notice with a Telefax (fax 213-267-5668).

The service commitment specified above shall not apply where Burlington Northern
Santa Fe is unable to perform due to an Act of God, strikes, lockouts, wrecks,
mechanical breakdowns in equipment or facilities of Burlington Northern Santa
Fe, CSI or its agent, or any act or failure to act on the part of CSI or its
agent.


                                     Page 3
<PAGE>

By way of clarification, derailments of empty unit trains, or any portion
thereof, or collisions with other vehicles or objects while enroute to CSI or
its agent at Los Angeles Harbor to meet a prescheduled empty train loading
appointment, shall not constitute grounds for exclusion from Service Commitment
requirements and responsibilities.

9. DEMURRAGE PROVISIONS

"Thirty-six (36) hours free time will be allowed for loading cars at Origin and
thirty-six (36) hours free time will be allowed for unloading cars at
Destination, regardless of the number of cars placed. The free time shall be

placement of the cars, excluding Saturday, Sunday or Holidays."

Liquidated Damages section of the Contract.

19. SEVERABILITY

to be unenforceable, illegal, against public policy, or in conflict with any
federal, state or local laws, shall be severable from the rest of the Contract.
The remaining portions of the Contract or Amendments thereto shall not be
affected. The rights and obligations of the parties shall be construed and
inferred as if the Contract did not contain the particular term, part, or
provision held to be invalid, unless the invalid provisions contain the material
financial terms of this Contract, or when considered in the aggregate, render
the administration of this Contract unreasonably burdensome, in which case
(unless new terms or provisions can be negotiated within three (3) months of
written request for renegotiation by either party) this Contract and Amendments
thereto shall be terminated. In the event of termination, the Minimum Volume
requirement of this Contract and Amendments thereto will be waived for the then
