ARTICLE II

                         SCOPE OF TRANSPORTATION SERVICE

2.1. Transportation of Carbon Dioxide. Subject to all of the terms, conditions,
and limitations of this Agreement, each day during the term hereof Shipper shall
have the right to tender to Transporter at the Receipt Points set forth in
Exhibit A (the "Receipt Points") for transportation hereunder any volume of
Carbon Dioxide up to the Daily Maximum Quantity.

2.2. Redelivery of Carbon Dioxide. Subject to all of the terms, conditions, and
limitations of this Agreement, each day during the term hereof Transporter shall
redeliver to Shipper, at the Delivery Points set forth in Exhibit B (the
"Delivery Points"), the volume of Carbon Dioxide delivered by Shipper to
Transporter at the Receipt Points on such day, as such volumes may be adjusted
for Shipper's proportionate share of reductions due to Carbon Dioxide lost and
unaccounted for in Transporter's Pipeline and any other loss or shrinkage factor
generally applicable from time to time to Transporter's Pipeline.

2.3. Non-Exclusive Transportation. Subject to the qualification as to priority
set out in Section 2.4, nothing in this Agreement shall be construed to prohibit
Transporter from transporting Carbon Dioxide for a person or persons other than
Shipper. Nothing in this Agreement shall be construed to require Shipper to
tender any minimum quantity of Carbon Dioxide to Transporter for transportation
hereunder.

2.4. INTENTIONALLY OMITTED.

2.5. Operation of Transporter's Pipeline. Except as otherwise provided in
Section 2.8, Transporter will at all times maintain, preserve and keep all
improvements, machinery, equipment, pipe lines, tanks, fixtures and other
personal property and equipment of every kind and nature now or hereafter
required in connection with operation of Transporter's Pipeline in good repair,
working order and condition, and promptly make all necessary and proper repairs,
renewals, replacements and substitutions. Subject to the forgoing and its other
obligations hereunder, Transporter may, at its sole discretion, at any time and
from time to time, expand, extend, repair, reconfigure or temporarily shutdown
Transporter's Pipeline and related equipment. In exercising the foregoing
rights, Transporter shall have no liability to Shipper hereunder and shall use
all reasonable efforts to minimize any adverse impact on Shipper's rights
hereunder.

2.6. Transporter's Processing Rights. Transporter reserves the right, prior to
delivery to Shipper at the Delivery Points set forth herein, at the sole cost of
Transporter, to process and/or treat Carbon Dioxide received from Shipper
hereunder for any purpose; provided, however, subject to Section 7.3, Carbon
Dioxide delivered to the Delivery Points shall meet the quality specifications
of Article VII hereof.

2.7. Excess Quantities. Shipper may, on any day and upon prior notice to
Transporter, tender at the Receipt Point volumes of Carbon Dioxide in excess of
the Daily Maximum Quantity, in which event Transporter may, in its sole
judgment, transport all or any portion of such excess volumes on a fully
interruptible basis. However, the transportation of any excess volumes by
Transporter shall otherwise be subject to all of the terms and provisions
hereof.

2.8. Call Option. In the event a Triggering Event (as hereinafter defined)
occurs, Transporter shall have the right and option to either (i) repair,
replace, restore and reconstruct Transporter's Pipeline in substantially the
form in which the same existed prior to any such Triggering Event or (ii)
exercise (or cause the exercise of) the Call Option provided for in Section 2.4
of the Second Master Agreement. Transporter shall notify Shipper in writing of
its election of one of the options set forth above within thirty (30) days from
the date of the Triggering Event. If Transporter elects the option set out in
clause (i) above, then Transporter shall commence the restoration work within
thirty (30) days from the date of the Triggering Event and diligently prosecute
and complete the restoration work within a reasonable time, in no event
exceeding twelve (12) months from the date of the Triggering Event. If
Transporter elects the option set forth in clause (ii) above, the Call Option
set forth in Section 2.4 of the Second Master Agreement shall be exercised in
accordance with the terms thereof. If Transporter fails to notify Shipper of its
election of either clause (i) or (ii) above within thirty (30) days from the
date of the Triggering Event, Transporter shall, as of such date, be deemed to
have delivered notice to Shipper electing to exercise the option set forth in
clause (i) above. For purposes hereof, a "Triggering Event" means (a) the entire
or partial destruction or damage of Transporter's Pipeline by fire or any other
casualty whatsoever; or (b) a mechanic failure or other breakdown of
Transporter's Pipeline, which in either case actually renders Transporter's
Pipeline inoperable for a minimum period of ninety-five (95) consecutive days.

ARTICLE III

                                RATES AND CHARGES

3.1. Initial Rate. For the transportation and dehydration of each MCF of
Shipper's Carbon Dioxide received at the Receipt Points during any month,
beginning with the date of first deliveries hereunder and continuing through the
end of the first Contract Year, Shipper shall pay Transporter a transportation
fee (the "Transportation Fee"), which fee shall initially be $0.16 (the "initial
rate").
3.2. Adjusted Rate. Effective on the first day of each Contract Year after the
first Contract Year, the Transportation Fee shall be adjusted, upward or
downward. Computations to determine such adjustments shall be made utilizing
$0.16/Mcf as the base rate. The adjustment shall be based upon the change in the
annual average of the Producers Price Index, "PPI," All Commodities, 1982 = 100,
as published by the United States Department of Labor, Bureau of Labor
Statistics. To determine the adjusted rate for each subsequent Contract Year,
the following formula shall be used:

                  Adjusted rate = Base rate x (0.10 + 0.90 x PPI current/PPI
                  base) or the initial rate, whichever is greater.

                  Thus, by way of illustration, should the average PPI for the
                  year 2002 be 125, and the average PPI for the year 2003 be
                  130, the adjusted price for the subsequent Contract Year,
                  2004, commencing on the anniversary of the Contract Year,
                  would be computed as follows:

                           $0.16 x (0.10 + 0.90 x 130/125) = $0.16576

3.3. Minimum Rate. Notwithstanding the foregoing, the Transportation Fee, as
adjusted herein, shall never be less than $0.16 per MCF.

3.4. Tax Reimbursement. In addition to the Transportation Fee provided for
above, Shipper shall reimburse Transporter for all taxes which are levied upon
and/or paid by Transporter with respect to the services performed under this
Agreement, but only if and to the extent that Shipper has the right to receive
reimbursement for such taxes from Shipper's customers under the terms of
Shipper's resale contracts with its customers.

ARTICLE IV

                       TERM; EARLY TERMINATION FOR DEFAULT

4.1.     Term. Subject to the other provisions hereof, this Agreement shall be
         effective from the date hereof and shall continue in force and effect
         until the Second Production Payment is fully discharged.

4.2.     Default. The occurrence of one or more of the following matters shall
         constitute a default by a party:

(a)      the occurrence of a Bankruptcy Event involving such party;

(b)      the failure of such party to make any payment to the other party as and
         when due hereunder where such failure continues for thirty (30) days
         after the delivery of written notice by the other party of such failure
         to make such payment; and

(c)      the breach by such party of any other material covenant, agreement,
         obligation, duty or provision of this Agreement, where such breach
         continues for thirty (30)days after its receipt of written notice
         thereof from the other party; provided, however, that if the matter
         which is the subject of the breach cannot by its nature with due
         diligence be remedied by such within said thirty (30) day period, and
         such party shall have prepared a plan for remedying such failure that
         is reasonably acceptable to the other party and such party is
         proceeding with diligence to implement such plan, such thirty (30)day
         period shall be extended by such additional time period as may be
         reasonably required to implement such plan, and, provided further,
         however, that the remedying of such potential default shall not affect
         the right of the other party to terminate this Agreement if other
         defaults occur before such potential default has been remedied.

4.3.     Occurrence of Default. Upon the occurrence of a default by a party, the
         other party may exercise any right or remedy it may have at law and/or
         in equity; provided that Transporter shall not be entitled to terminate
         this Agreement. If pursuant to an arbitration proceeding conducted in
         accordance with Section 14.9, it is determined that as a result of a
         Shipper default Transporter has suffered a specified amount of damages,
         the arbitrators may provided as a remedy to Transporter that
         Transporter may sell a portion of Shipper's carbon dioxide necessary to
         generate sufficient proceeds to reimburse Transporter for such damages.

ARTICLE V

                  RECEIPT POINTS, DELIVERY POINTS AND PRESSURES

5.1. Receipt Points and Delivery Points. The Receipt Points are set forth on
Exhibit A. The Delivery Points are set forth on Exhibit B. Shipper may request
at any time and from time to time that Transporter agree to one or more
additional Receipt Points or Delivery Points on Transporter's Pipeline.
Transporter shall not unreasonably withhold its agreement to the addition of any
additional Receipt Point or Delivery Point requested by Shipper as long as
Shipper reimburses Transporter for all incremental costs incurred or to be
incurred by Transporter as a result of the addition of such Receipt Point or
Delivery Point and, with respect to requested Receipt Points only, so long as
Transporter owns or controls the well or wells to be producing into the
requested Receipt Point. If Transporter's estimated incremental cost to
establish an additional Receipt Point or Delivery Point requested by Shipper
exceeds $25,000, then Transporter shall be entitled to require that Shipper pay
Transporter such estimated incremental cost before agreeing to add such
additional Receipt Point or Delivery Point, with a "true-up" payment being made
by the appropriate party to the other party when the final, actual incremental
costs of such additional Receipt Point or Delivery Point are known. Upon the
addition of any Receipt Point or Delivery Point, the parties shall execute an
amendment of this Agreement which shall reflect all of the Receipt Points or
Delivery Points on a revised Exhibit A or Exhibit B, as appropriate. The exact
point at which delivery by Transporter to Shipper shall be deemed to be made
shall be the flange or weld connecting the facilities of Transporter's Pipeline
with the facilities of Shipper or Shipper's designee.

5.2. Responsibility. As between the parties hereto, and subject to the
limitations set forth in other provisions of this Agreement, Transporter shall
be responsible for any injuries, losses, expenses, claims, liabilities, or
damages caused by the Carbon Dioxide while it is in Transporter's Pipeline until
it shall have been delivered to Shipper or Shipper's designee at the Delivery
Points, and, after such delivery, Shipper shall be responsible for any injuries,
losses, expenses, claims, liabilities, or damages caused thereby. Subject to the
limitations set forth in other provisions of this Agreement, each party (the
"Indemnifying Party") shall indemnify the other party in respect of any
injuries, losses, expenses, claims, liabilities, or damages occurring while the
Carbon Dioxide is in possession of the Indemnifying Party. Transporter shall not
take title to Shipper's Carbon Dioxide in Transporter's Pipeline merely by
receipt of such Carbon Dioxide for Shipper's account

5.3. Pressure Criteria. All Carbon Dioxide tendered by Shipper at any Receipt
Point shall be delivered at pressures sufficient to enter Transporter's Pipeline
at the working pressures maintained by Transporter at such Receipt Point from
time to time. Transporter shall deliver the volumes of Carbon Dioxide as
provided for hereunder at the Delivery Points at pressures ranging from 1100 to
1400 psig. Notwithstanding the foregoing, Transporter reserves the right at any
time and from time to time, to revise the maximum and/or the minimum pressures
set forth above on ten (10) days' prior notice to Shipper to the extent the
implementation of any such revision is prudent in light of the operating
conditions on the Transporter's Pipeline.

ARTICLE VI

                                    QUANTITY

6.1. Delivery Rates. Transporter and Shipper shall endeavor to deliver and to
accept, respectively, Carbon Dioxide in as reasonable constant rates as is
practicable. Transporter and Shipper understand and agree that the amount of
Carbon Dioxide delivered hereunder from time to time may not exactly equate with
the volume of Carbon Dioxide requested for delivery hereunder since variations
may occur due to the inherent fluctuations in normal pipeline operations. Upon
request from Shipper, Transporter may deliver Carbon Dioxide on any day in
excess of the Daily Maximum Quantity, but Transporter shall not be obligated to
do so.

6.2. Cooperation Regarding Deliveries. Shipper or Shipper's agent shall notify
Transporter monthly, in advance, of Shipper's estimated daily requirements at
each of the Receipt Points and the Delivery Points for the next succeeding month
and Transporter shall deliver such requirements, up to the Daily Maximum
Quantity, out of the volumes received by Transporter at the Receipt Points for
Shipper's account. Transporter and to the extent it will not result in a default
under a Industrial Sale Contract, Shipper agree to fully cooperate with each
other in adjusting monthly and daily deliveries hereunder. Shipper or Shipper's
agent shall give twenty-four (24) hours' prior notice of any additional changes
in its daily requirements as may be necessary from time to time and, on receipt
of such notice by Shipper, Transporter shall undertake as soon as practicable to
conform its deliveries to Shipper's revised daily requirements (up to the Daily
Maximum Quantity) and shall notify Shipper as soon as practicable if Transporter
is unable to do so. In the event of an emergency which poses danger to life or
property, no prior notice shall be necessary before partial or total shutdown by
either party, but notice of such shutdown and the reason therefor shall be given
as soon as practicable thereafter. If a shutdown becomes necessary for either
party on a non-emergency basis, such party shall give at least twenty-four (24)
hours' prior notice to the other party.

ARTICLE VII

                             QUALITY SPECIFICATIONS

7.1.     Specification. The Carbon Dioxide delivered by Transporter to Shipper
         at the Delivery Points shall meet the following specifications
         (collectively the "Quality Specification"):

(a)      Water. The Carbon Dioxide shall not contain any free water and the
         water vapor content shall not exceed thirty (30) pounds per MMcf.

(b)      Hydrogen sulfide and sulfur. The Carbon Dioxide shall not contain more
         than 10 parts by weight of hydrogen sulphide nor more than 35 parts by
         weight of total sulfur per 1,000,000 parts of Carbon Dioxide.

7.2.     Testing. Transporter shall ensure that tests to determine the quality
         of Carbon Dioxide are conducted as often as necessary in Transporter's
         sole opinion, utilizing approved standard methods in general use.
         Transporter may furnish Shipper with copies of all test results.
         Transporter shall give Shipper reasonable notice of all such tests in
         order that Shipper or Shipper's agent may have its representative
         present, if Shipper so desires.

7.3.     Disclaimer. THE PARTIES HERETO RECOGNIZE AND AGREE THAT TRANSPORTER IS
         NOT A MERCHANT OF FOOD GRADE OR MERCHANTABLE CARBON DIOXIDE FOR USE IN
         FOOD OR DRINK OR OTHER CONSUMABLES AND TRANSPORTER IN NO WAY WARRANTS
         THE MERCHANTABILITY OR FITNESS OF ANY CARBON DIOXIDE DELIVERED OR TO BE
         DELIVERED HEREUNDER FOR ANY PARTICULAR PURPOSE.

ARTICLE VIII

                      OWNERSHIP AND OPERATION OF FACILITIES

8.1. Facility Ownership. Transporter will own, operate and maintain the
Transporter's Pipeline, and the pipelines and measurement facilities, including
any additional equipment installed by or at the request of Shipper, at each
Receipt Point and at each Delivery Point. Transporter will maintain Carbon
Dioxide custody to the upstream flange of Shipper's valve on the outlet side of
Transporter's measurement facilities at each Delivery Point. Transporter shall
be solely responsible for the delivery of Carbon Dioxide to the inlet side of
Shipper's tap valve at each Delivery Point. All piping downstream from the

shall be accumulated during each month and analyzed for its composition by gas
chromatograph or other methods agreed to by Transporter and Shipper, at
Transporter's expense.

ARTICLE X

                                  FORCE MAJEURE

10.1. Definition. If, while this Agreement is in effect, either party is
rendered unable, wholly or in part, by Force Majeure to carry out its
obligations (except financial obligations) under this Agreement, it is agreed
that, on such party's giving notice and reasonably full particulars of such
Force Majeure in writing to the other party within ten (10) business days after
the occurrence of the Force Majeure relied on, then the obligations of the party
giving such notice, so far as they are affected by such Force Majeure, shall be
suspended during the continuance of any inability so caused, but for no longer
period, and such cause shall so far as possible be remedied with all reasonable
dispatch. The term "Force Majeure", as used herein, shall mean acts of God,
strikes, lockouts or other industrial disturbances, acts of the public enemy,
wars, terrorism, blockades, insurrections, riots, epidemics, landslides,
lightning, earthquakes, fires, storms, floods, high water, washouts, arrests and
restraints of government and people, civil disturbances, explosions, breakage or
accident to machinery or lines of pipe, freezing of wells or lines of pipe,
partial or entire failure of wells, and any other causes, whether of the kind
herein enumerated or otherwise, not reasonably within the control of the party
claiming Force Majeure. Without limiting the generality of the foregoing, the
term "Force Majeure" shall likewise include (a) in those instances where either
party hereto is required to obtain servitudes, rights-of-way grants, permits or
licenses to enable such party to perform hereunder, the inability of such party
to acquire, or the delays on the part of such party in acquiring, at reasonable
cost and after the exercise of reasonable diligence, such servitudes,
rights-of-way grants, permits or licenses, and (b) in those instances where
either party hereto is required to furnish materials and supplies for the
purpose of constructing or maintaining facilities or is required to secure
permits or permissions from any governmental agency to enable such party to
perform hereunder, the inability of such party to acquire, or the delays on the
part of such party in acquiring, at reasonable cost and after the exercise of
reasonable diligence, such materials and supplies, permits and permissions. An
occurrence of Force Majeure affecting Transporter's supply sources or processing
facilities or gathering system or Transporter's Pipeline shall be deemed to be
an occurrence of Force Majeure affecting Transporter hereunder.

10.2. Extended Force Majeure. If, after deliveries have commenced hereunder, an
event of Force Majeure significantly affects the amount of Carbon Dioxide
Transporter is capable of delivering for a consecutive period of 180 days, then,
at any time after such period and prior to the time such event has been
remedied, Shipper may cancel this Agreement.

10.3. Strikes and Lockouts. It is understood and agreed that the settlement of
strikes or lockouts shall be entirely within the discretion of the party having
the difficulty and that the above requirement that any Force Majeure shall be
remedied with all reasonable dispatch shall not require the settlement of
strikes or lockouts by acceding to the demands of any opposing party when such
course is inadvisable in the discretion of the party having the difficulty.

any error or inaccuracy in its own or the other party's statement, payment,
calculation, or determination, then proper adjustment and correction thereof
shall be made as promptly as practicable thereafter, except that no adjustment
or correction shall be made for an error or inaccuracy if more than two (2)
Contract Years have elapsed since the end of the Contract Year in which such
error or inaccuracy occurred.

12.3. Failure to Pay. If Shipper fails to pay any amount payable to Transporter
hereunder when due, interest thereon shall accrue and be payable at the lesser
of (i) the highest legally permissible rate or (ii) the prime lending rate, plus
an additional five percent (5%), established by the Chase Manhattan Bank, N.A.,
New York, from the date when payment was due until the date payment is made. If
such failure to pay any amount continues for thirty (30) days or more after the
due date of such amount for any reason, then (a) Transporter may suspend its
deliveries of Carbon Dioxide hereunder, (b) Transporter shall have the right to
make direct deliveries in satisfaction of the delivery requirements in the

Agreement, should Transporter reasonably believe it necessary to assure payment
for transportation of Carbon Dioxide being delivered or to be delivered
hereunder, Transporter may at any time, require (i) advance cash payment; (ii) a
standby irrevocable letter of credit at Shipper's expense in a form and from a
bank acceptable to Transporter, in Transporter's sole opinion; or (iii) other
security of a type and form and amount which may be deemed reasonably
satisfactory to Transporter. In the event banking or credit information
requested by Transporter has not been furnished within a reasonable time in
Transporter's sole opinion, Transporter shall have the right, with five (5)
days' prior notice, to withhold and/or suspend deliveries hereunder, in addition
to any and all other remedies available hereunder; provided that Transporter
shall not have the right to terminate this Agreement.

ARTICLE XIII

                                    WARRANTY

13.1. Warranty. Each party warrants, for itself, its successors, heirs, legal
