manner and minimizing any hazards associated with the storage of SDSP's
Products.

WESTWAY agrees to have Facility completed and ready to accept delivery for
storage and redelivery (as herein provided) of Product at the time and in the

prior to initial delivery of Product; it being assumed that Facility is
satisfactory unless SDSP shall otherwise timely notify WESTWAY in writing.

1.02  TANK USE AND CLEANING

SDSP agrees to pay cost of cleaning its Product and disposing of cleaning
materials and residue waste from the Facilities following use of the Facilities
for storage of its Product, at a permitted facility, approved by SDSP. In the
event WESTWAY arranges for the cleaning and disposal services, SDSP will only be
responsible for the costs and liable if SDSP has approved the cleaning and
disposal contractor and procedures, and disposal site. All terms and provisions
of this Agreement shall continue in full force and effect until both Product and
waste are removed from WESTWAY's premises.

1.03  ADDITIONAL EQUIPMENT

facilities or equipment. Except as otherwise provided in Schedule I, SDSP
shall at least bi-annually, and more often if circumstances and conditions so
warrant, inspect said facilities or equipment and shall be responsible for
maintenance and repair of said facilities or equipment to ensure their
continued safe performance during the term of this Agreement unless the
repair is necessitated by the negligence of WESTWAY. WESTWAY agrees to notify
SDSP of any obvious condition in need of repair maintenance. Should any
release or threatened release of any hazardous substance, as defined under
any federal state, or local law, ordinance or regulation, occur due to
failure of or defect in said facilities or equipment, SDSP shall be liable to
WESTWAY for any fines, penalties, loss, damage, or expense, including any
necessary cleanup of hazardous materials released or threatened to be
released into the environment and reasonable legal fees.

facilities or equipment and any cost to restore WESTWAY's premises to their
original condition.

1.04  DOCK

SDSP's expense.

WESTWAY will supply SDSP with a monthly inventory of the Product. A month-end
physical inventory shall be taken each month by WESTWAY. Any variances

6.  INDEPENDENT CONTRACTOR

Nothing contained herein shall create the relationship of joint venture,
principle and agent or master and servant between SDSP and WESTWAY and except
for purposes of issuance of bills of lading pursuant to this Section 2.02 or
for purposes of insuring payment of invoices as provided in Section 5,
WESTWAY, in the performance of this Agreement, is not and shall not act or
purport to act as the agent or employee of SDSP, but is and shall act as an
independent contractor. WESTWAY acknowledges that it is solely responsible
for and solely in control of operations at the Facility; SDSP shall not
exercise any control over or direction of the manner in which WESTWAY
performs the services called for under this Agreement.

7.  QUALITY ASSURANCE

The independent surveyor engaged by SDSP, or, in his absence by WESTWAY, will
perform sampling of contents of such tanks and of the receiving pipeline
before, during and after loading or off-loading of vessel or bare. Duplicate
one (1) quart composite thief samples shall be taken from


<Page>

top, middle and bottom of each tank being sampled prior to loading or
off-loading, and from tank upon completion of off-loading or loading. A
duplicate one (1) quart sample shall be taken from WESTWAY's receiving
pipeline prior to, and at least hourly, during loading or off-loading. One
(1) full set thereof shall be placed aside for WESTWAY.

From the other set, the surveyor shall prepare a one (1) quart composite
sample from each vessel tank and from Facility tank by combining one third of
each thief sample from the particular tank; similarly, the surveyor shall
make a one (1) quart composite sample from the receiving pipeline by
combining equal quantities of the samples from said pipeline. The composite
samples shall be sent, at SDSP's expense, to a laboratory or others to be
designated by SDSP. The remainder of the sample set from which the composite
samples were combined shall be retained by WESTWAY along with the full
duplicate set for a period of at least ninety (90) days, after which the
samples shall be disposed of by WESTWAY at a permitted facility at SDSP's
cost.

WESTWAY, if requested by SDSP, will take a one (1) quart sample from each
shipment out of Facility and retain such properly identified sample for a
period of thirty (30) days and disposed of by WESTWAY at a permitted Facility
at SDSP's costs unless SDSP shall otherwise request in writing.

8.  RESPONSIBILITY FOR PRODUCT

WESTWAY will be responsible for any loss of Product while in storage in
excess of 1% of amount received. Overages and shortages shall be averaged
against each other over each contract year of the Agreement and any shortages
accounted for by WESTWAY to SDSP at the end of each contract year. WESTWAY
shall not, without instruction from SDSP, add anything to Product in storage.

SDSP shall be responsible for the Product until it leaves the delivery
carrier. WESTWAY's responsibility shall commence when Product is off-loaded
into WESTWAY's Facility and continues until Product passes from the last
flange into the shipping carrier. The amount of any Product lost due to leaks
or destruction of tank cars or tank trucks during the loading or off-loading
shall be borne by SDSP.

WESTWAY shall not be responsible for change in quality, color, or condition
of the Product stored or handled unless caused solely by WESTWAY's
negligence. SDSP shall indemnify and hold WESTWAY harmless, for any loss or
damage incurred by reason of a delivery to Facility of any Product identified
as Product, but is, in fact, of a different chemical composition, or if
WESTWAY takes any action, without negligence on WESTWAY'S part, with respect
thereto at the request or direction of SDSP.

9.  CHARGES AND PAYMENT

9.01  TERMINATION CHARGE

required by any public or private agency particular to the storage and
handling of SDSP's Product at WESTWAY's Facilities, provided such costs not

shall apply.

(b) Subject to the terms and conditions herein, SDSP will pay WESTWAY for the
cost to clean such tank(s) and dispose of residuals in the event SDSP's use
of the tank is discontinued and the tank becomes available for use by WESTWAY
to store other product or materials. Subject to the terms and conditions
herein, if the tank(s) should require cleaning during the term of the
contract, due to any cause other than WESTWAY's negligence, SDSP will also
pay all costs of such cleaning and disposal of residuals.

the next contract month; such invoices will reflect the portion of the
minimum annual thruput charge due to date. Monthly payments made in contract

to date or so much of minimum annual thruput charge as is due to date; a
charge for other services rendered in the contract month just ended will be
added to monthly invoices.


<Page>

reflect any increase or decrease in fuel rates provided that no increase
shall be greater than fourteen (14%) percent annually.

WESTWAY reserves the right to revise truck weighing charges at the end of
each contract year, limited to the extent WESTWAY can justify such adjusted
weighing charge by documentary evidence up to 5% annually.

If requested, WESTWAY will submit evidence of new and old rates at time of
escalation.

handling of SDSP's Product shall be treated as, or result in, a taxable sale
or use or, in the event this Agreement or the Product stored shall be subject
to any ad valorem tax, all such taxes shall be borne by SDSP invoiced as an
added charge; and provided, however, that SDSP shall have the full right to
contest the same at its cost and expense, with WESTWAY's reasonable
assistance and cooperation, which WESTWAY shall not unreasonably refuse.

13.01  EXTENT OF WESTWAY'S LIABILITY

Risk of loss of Product due to fire, storm or other casualty shall remain
with SDSP to the extent the Product is covered by SDSP's all risk insurance

Product. WESTWAY's liability for such loss or damage is limited to SDSP's
lowest FOB Volga wholesale price during the contract year in which the loss
occurred.

WESTWAY shall be responsible for all Facility deterioration resulting from
storage of Product, as long as such Product is within specifications
enumerated in the attached Schedules and delivered according to the terms and
conditions of this Agreement. In the event WESTWAY's facilities are damaged
or destroyed, WESTWAY may, at its option, rebuild such facilities so affected
or substitute mutually agreeable facilities for SDSP's Product within thirty
(30) days at rates specified in Schedule 1, throughout the remaining term of
this Agreement.

SDSP shall be obligated to notify WESTWAY of any Product characteristics
which may cause excess deterioration to Facilities beyond normal wear and
tear. In addition to SDSP's obligations pursuant to 17.01, should

SDSP's failure to deliver the Product specified or to accurately inform
WESTWAY of the Products hazards, SDSP shall be liable for repair and/or
replacement of such Facilities. In such event, SDSP shall continue to be
responsible for charges throughout the entire period of time required to
complete such repair and/or replacement unless such repair and/or replacement
exceeds a reasonable time frame as mutually agreed both parties prior to
commencement of said repair and/or replacement.

14.  FORCE MAJEURE

tank set aside to service SDSP's Product be damaged or destroyed, WESTWAY
shall be relieved, without incurring any liability to SDSP, of all WESTWAY's

destruction or damage. In such event or in the event Force Majeure is
sustained by SDSP, SDSP shall at the same time be relieved of all obligations
to pay all or the allocable part of any monthly rental and attributable other
charges then in effect to the extent such failure to perform or such
deficiency in making annual thruput payments is caused by, arises out of or
is attributed to any cause reasonably beyond control of SDSP, such as but not
limited to war; riot; explosion; flood; storm; earthquake; act of God; perils
of the sea; labor disputes; sabotage; accident; embargo; breakage of
machinery or apparatus; injunction; compliance with governmental order; or
inability to obtain fuel; raw materials; labor; containers, or transportation
difficulties preventing the manufacture or shipment of product or restriction
imposed by SDSP (any such cause being referred to as "Force Majeure"). Should
any Force Majeure occur, the party experiencing the


<Page>

Force Majeure will promptly notify the other party of its existence, the
reasons why and approximately how long a delay is expected.

15.  DEFAULT BY EITHER PARTY

observance of the terms or conditions of this Agreement and should any such
default continue for thirty (30) or more days after written notice thereof to
the defaulting party, then the non-defaulting party shall have the right to
cancel and terminate this Agreement and to recover damages or seek any other
relief which it may be entitled at law or in equity.

Should either party be adjudicated bankrupt or insolvent in an involuntary
proceeding, or if such party shall have filed a petition for an arrangement
of creditors under the bankruptcy laws or insolvency laws of any
jurisdiction, or if a bankruptcy or insolvency proceeding is instituted
against such party which is not set aside within thirty (30) days thereafter,
then, in that event, such party shall be deemed to be in default of this
Agreement, thereby entitling the other party hereto to treat this Agreement,
in accordance with the foregoing, as being in default.
