   9
2.1       This contract shall be in effect from July 1, 1999 until October 19,
          2003. The contract term shall be automatically extended past October
          19, 2003 until notice of termination is given by either party at least
          twenty-four (24) months before the desired termination date. A notice
          of termination must be in writing.

                 Article 3 - Service to be Provided by Cogenron

3.1       Upon request by UCC Cogenron will furnish UCC with 300,000 lbs/hour of
          steam on a monthly average basis. Nevertheless, at no point shall
          Cogenron be required to deliver more than 600,000 lbs/hour on an
          instantaneous basis.

3.2       Cogenron will also provide UCC with an additional 300,000 lbs/hour of
          steam for up to seven (7) times per year not to exceed a cumulative
          total of eight hundred forty (840) hours in any calendar year. This
          right as provided by this Article 3.2 to additional steam is
          hereinafter referred to as a "Call Option." This Call Option is
          intended to provide UCC with incremental steam quantities necessitated
          by performance of maintenance at customer's facility and shall be
          declared in advance of the event. For the period from July 1, 1999

          times not to exceed a cumulative total of seven hundred twenty (720)
          hours. If this Agreement has not been terminated by October 19, 2003
          for the period from October 20, 2003 through the termination date of
          the contract, the Call Option may be exercised on a pro rata basis
          (rounded down) for up to seven (7) times per twelve (12) month period
          not to exceed a cumulative total of 840 hours per twelve (12) month
          period.

3.3       The quantities of steam described in articles 3.1 and 3.2 shall be
          referred to as "Base Stearn Quantities."

3.4       Upon request by UCC Cogenron shall, if available, furnish UCC
          incremental "Supplemental Steam Quantities" in excess of the Base
          Stearn Quantities. It is within Cogenron's discretion as to whether
          Supplemental Stearn Quantities are available.

3.5       During UCC's plant normal operation, UCC's designated employee shall
          verbally notify Cogenron once at the beginning of each twelve (12)
          hour work shift, or as otherwise mutually agreed, of the quantity of
          steam Customer anticipates taking from Cogenron during said work
          shift.

3.6       At the beginning of each calendar month, UCC shall provide Cogenron
          with its reasonable best estimate of projected Call Option dates for
          the succeeding twelve (12) months. 

                               Article 4 - Price

4.1       Each month, UCC shall pay Cogenron (1) a Facilities Charge; and (2) a
          Monthly Steam Charge. The Monthly Steam Charge, based on steam
          deliveries, is comprised of a monthly charge for Base Stearn
          Quantities and a monthly charge for Supplemental Stearn Quantities.

4.2       The Facilities Charge is & 100,000 per month.


   10
4.3       The monthly charge for Base Steam Quantities is comprised of a Fuel
          Component and an Operations and Maintenance Component.

4.3.1     The Fuel Component is calculated by multiplying Cogenron's total
          weighted average cost of gas ("Cogen Fuel Cost") for the applicable
          month by a fixed "Equivalent Boiler Rate" of 1.2760 mBtu/lb. Cogen
          Fuel Cost, expressed in $/mmBtu, shall be computed as the total
          commodity cost of gas consumed by Cogenron's Texas City facilities
          during the month, including any demand and scheduling or reservation
          charges, divided by the total quantity of fuel consumed during the
          applicable month. The Fuel Component will be adjusted monthly.

4.3.2     Cogenron shall present to UCC any proposed gas supply arrangement(s)
          required to produce requested steam quantities under this Agreement.
          Cogenron cannot enter into such a gas supply arrangement(s) until
          written approval is given by UCC In the event UCC does not provide
          written approval of a proposed gas supply arrangement(s) UCC will
          provide the gas quantities necessary to provide the requested steam
          quantities under this Agreement. UCC will be required to provide the
          gas quantities necessary to produce the requested steam quantities
          under this Agreement until such time as UCC directs Cogenron to secure
          a third-party gas contract and UCC approves the proposed third-party
          gas contract. Cogenron shall not terminate or amend such approved gas
          supply arrangement(s) without prior written approval from UCC

4.3.3     Notwithstanding Article 4.3.2, upon delivery of notice by July 1,
          1998, UCC may elect to supply such gas quantities necessary to produce
          requested steam quantities for the term of this Agreement. Such gas
          quantities shall meet the specifications as set forth in Appendix 3.
          If UCC elects to provide gas quantities and fails to supply gas
          quantities equal to the amount necessary to produce requested steam
          quantities (calculated based on the Equivalent Boiler Rate), UCC shall
          reimburse Cogenron for the replacement cost of natural gas, including
          any imbalance premiums or other charges. Such reimbursement shall be
          calculated by Cogenron in accordance with Article 4.6.

4.3.4     The Operations and Maintenance Component is $0.30/mlb of steam.

4.4       The monthly charge for Supplemental Steam Quantities is the monthly
          charge for Base Steam- Quantities plus $0.50/mlb.

4.5       For billing purposes, monthly average steam deliveries (adjusted for
          steam deliveries associated with the Call Option) will be used to
          determine Base Steam Quantities and Supplemental Steam Quantities.
          Nevertheless, should UCC request instantaneous steam deliveries in
          excess of 600,000 lbs/hour and Cogenron elects to deliver such
          requested quantities, such amounts in excess of 600,000 lbs/hour for
          each hour shall be billed at the monthly charge for Supplemental
          Stearn Quantities.

4.6       The regular billing period shall be the calendar month. All invoices
          are due on presentation and payable within twenty (20) days of
          receipt. Late payments by UCC shall bear interest at UCC's then
          current short-term borrowing rate plus one percent (I%), not to exceed
          the maximum interest rate permitted to be charged by applicable law.

                         Article 5 - Point of Delivery

5.1       All steam under this contract will be delivered at the Point of
          Delivery. The Point of Delivery are those points specified in Appendix
          4. All right, title, and interest in and to any steam delivered under
          this Agreement shall pass from Cogenron to UCC at the Point of
          Delivery. Cogenron shall have the risk of loss of all steam to be
          delivered under this Agreement up to and at the Point of Delivery. UCC
          shall have the risk of loss of all steam delivered under this
          Agreement from and after the Point of Delivery. Notwithstanding the
          foregoing, if the loss of any steam is due to equipment, materials or
          processes or any other matter under the control and maintenance, as
          provided herein, of the party other than the one for which risk of
          loss has been allocated as provided above, such party shall be liable
          for the loss of any such steam. Liability for all damages caused by or
          arising out of the steam to be delivered hereunder shall lie with the
          party responsible for the risk of loss as specified in this article,
          except to the extent the damages are caused by the negligence or
          misconduct of the other party.

             Article 6 - Article 6 & Services to Be Provided by UCC

6.1       UCC shall, without charge, provide to Cogenron: (1) facilities to
          handle storm water runoff; (2) firewater; (3) wastewater treatment up
          to an instantaneous flow of 3,000 gallons per minute; and (4) boiler
          quality water in sufficient quantities to produce UCC's requested
          steam takes, including an additional amount for necessary and
          customary blowdown and losses, estimated at 1.5 percent. Such boiler
          quality water shall meet the specifications defined in Appendix 5.
          Should UCC fail to deliver boiler quality water in accordance with the
          specifications detailed in Appendix 5, Cogenron shall make best
          efforts to secure boiler quality water from third-party sources, upon
          approval by UCC to produce requested steam deliveries. If Cogenron is
          unsuccessful in securing boiler quality water from third-party sources
          that is in accordance with the specifications detailed in Appendix 5,
          Cogenron shall reduce such steam delivery to reflect actual receipt of
          boiler quality water that is in accordance with the specifications
          detailed in Appendix 5. UCC shall reimburse Cogenron for securing such
          boiler quality water.

6.2       UCC shall provide an average of 2,500 gallons per minute and up to a
          peak of 3,500 gallons per minute of river water to Cogenron, at UCC's
          direct cost.

6.3       UCC shall make reasonable efforts to continue to provide to Cogenron
          the services described in 6.1 and 6.2 after termination of this
          Agreement at a price to Cogenron that compensates UCC for the direct
          cost to provide such services, including a reasonable rate of return
          on assets employed by UCC to provide said services.

                       Article 7 - Ground Lease Agreement

7.1       UCC and Cogenron (successor in interest to Northern Cogeneration One
          Company) entered into a Ground Lease Agreement ("Lease"), dated
          January 1, 1986. A copy of the Lease is attached as Appendix 7. UCC
          and Cogenron agree to extend the Lease, and all rights and obligations

   12
          contained therein, for five (5) years beyond the termination of this
          Agreement. This includes, but is not limited to, Cogenron's right to
          purchase the premises from UCC as set forth in the Lease.

                           Article 8 - Steam Metering

8.1       Cogenron shall measure the amount of steam delivered hereunder by a
          mutually acceptable metering system at the Point of Delivery or at
          other mutually acceptable locations as specified in Appendix 4.

8.2       Meters shall be installed, repaired and replaced at Cogenron's
          expense. Meters will be tested and calibrated at Cogenron's expense in
          accordance with Appendix 6 and with the schedule specified in Article
          8.5. UCC may request meter tests at more frequent intervals. If such
          requested test determines the meter to be within the accuracy
          described herein, UCC will pay all reasonable costs for testing the
          meter.

8.3       If at any time, any meter or other equipment constituting an official
          meter station is found to be defective, such meter or equipment shall
          be readjusted, repaired, or replaced without delay. If, upon any
          calibration test, the inaccuracy of the meter or other equipment is
          found to affect the measurement of the steam delivered hereunder in
          excess of the specified amount when calculating such inaccuracy at the
          average flowing conditions experienced during the period following the
          previous calibration test, then an equitable adjustment and settlement
          in the invoices for prior deliveries shall be promptly made by the
          parties on the basis of best data available, using the first of the
          following methods which is feasible:

8.3.1     By using the recording of a check meter if available and accurately
          recording.

8.3.2     By correcting the error back to zero (0) after the percentage of error
          is ascertained by calibration, test, or mathematical calculation for
          the period of error, if known; or if unknown for a period extending
          back one-half (1/2) of the time since the last calibration; or

8.3.3     If data cannot be obtained from the official or check meters, then
          mutually agreeable data from Cogenron and UCC will be used to arrive
          at the official meter reading. This data may be in the form of other
          meters, production data, or previous and subsequent days' readings.

8.4       Cogenron shall provide notice of any meter test to UCC prior to making
          each test of such meter. Such notice may be oral but shall
          subsequently be confirmed in writing. UCC shall have the right to have
          a representative present at such test to observe the same and any
          meter adjustments found thereby to be necessary. UCC may provide at
          its own expense (but shall not be obligated to do so) a check meter at
          each delivery point and such check meter shall be used for measurement
          purposes hereunder, subject to all provisions herein, during any
          period when primary meter is inoperable or in such state of disrepair
          that accurate measurements cannot be obtained therefrom.

8.5       The steam metering system shall have the capability of measuring the
          hourly rat and quantity of steam delivered by Cogenron and received by
          UCC and shall be maintained within an accuracy range of plus or minus


   13
          one-and-a-half percent. Cogenron at its expense shall test the steam
          metering system at least monthly.

                           Article 9 - Force Majeure

9.1       Neither Cogenron nor UCC shall be liable to the other for failure to
          provide or take steam, or to perform any other obligation hereunder,
          or for any damages resulting from such failure to the extent that such
          failure or damage shall be the result of fire, strike, riot,
          explosion, flood, accident, acts of God, the public enemy,
          governmental laws, ordinances, rules or regulations (whether valid or
          invalid), or without limitation by enumeration, any other acts or
          circumstances beyond the reasonable control of either party,
          preventing or prohibiting in whole or in part such provision, taking
          or performance. Either party's failure to perform its obligations,
          either in whole or in part, under the terms of this Agreement to the
          extent resulting from a "year 2000 date change event" (i.e., due to
          the impact on time and date codes and the affected party's internal
          computer programs which impact is associated with the affected party's
          operations following December 31, 1999) shall not constitute a Force
          Majeure situation and is subject to any remedies that may be available
          under this Agreement.

                        Article 10 - Status of Facility

10.1      UCC shall take delivery and consume sufficient steam quantities to
          ensure that Cogenron's plant shall maintain its "Qualifying Facility"
          status as defined in 18 CFR (Code of Federal Regulations) 292 as of
          the date of the signing of this Agreement. UCC agrees that such steam
          shall be thermally used as required by such regulations. In the event
          that such rules and regulations governing "Qualifying Facilities"
          change, the parties agree to enter into good faith negotiations with
          an objective of' reaching a mutually satisfactory arrangement in order
          to continue the qualifying status of Cogenron's Plant.

                           Article 11 - Governing Law

11.1      This Agreement shall be governed by law of the State of Texas.

                            Article 12 - Assignments

12.1      Except as otherwise provided in this Article, neither party shall
          assign this Agreement, or any part thereof, without the prior consent
          of the other party and any assignment in violation of this provision
          shall be void. This Agreement shall be binding upon and shall inure to
          the benefit of the parties and their successors and permitted assigns.

12.2      Either party may assign its rights and obligations under this
          Agreement, subject to the prior written approval of the other party
          hereto, which approval shall not be unreasonably withheld, to any
          subsequent owner of all or substantially all of the assets of UCC's
          Plant, the Retrofit Equipment or Cogenron's Plant, as the case may be,
          if such subsequent owner accepts the assignment of this Agreement and
          assumes the obligations of the conveying party hereunder.

12.3      Either party shall have the right to assign this Agreement to a
          subsidiary of affiliate of such party without the consent of the other

   14
          party; provided that the assigning party shall not be released from
          its obligation hereunder.

                         Article 13 - Entire Agreement

13.1      This Agreement, together with the attached Appendixes, contain the
          entire understanding and Agreement between the parties. This Agreement

                          Article 18 - Default of UCC

18.1      The following shall each constitute an Event of Default by UCC under
          this Contract:

18.1.1    Failure of UCC to pay in full the charges billed to it by Cogenron for
          steam and reimbursement for purchase of boiler quality water as
          provided by Article 6.1 received pursuant to this Contract within a
          period of ninety (90) days after the date of invoice receipt, unless
          UCC shall in good faith be disputing the portion of such invoice that
          has not been paid; or

18.1.2    If UCC fails to perform any of the other material provisions of this
          Contract or otherwise endangers performance of the Contract in
          accordance with its terms; and in either of these two circumstances
          does not submit a proposed course of action within a period of thirty
          (30) days to correct such failure after receipt of notice from

18.1.3.1  UCC's bankruptcy or insolvency or the initiation of any proceeding,
          voluntary or involuntary, against UCC under the bankruptcy or
          insolvency laws, or UCC's failure to meet its debts in the ordinary
          course of business; provided, however, that there shall be no Event of
          Default if, within thirty (30) days from the written receipt of notice
          from Cogenron to terminate for such default, UCC as debtor in
          possession or UCC's trustee, receiver, assignee or custodian,
          whichever is obligee under this Contract, in writing affirms this
          Contract and the Lease and demonstrates to Cogenron' s reasonable
          satisfaction the ability to fulfill its or their obligations under
          this Contract, and the Lease; or

18.1.3.2  UCC makes an assignment of all or a substantial part of UCC's Plant or
          UCC's Land for the benefit of creditors.

18.2      Cogenron may, at its sole option, in the event of an occurrence of an
          Event of Default as defined in Section 18. 1, exercise any or all of
          the following remedies by written notice of default to UCC which shall
          constitute the sole and exclusive remedies available to Cogenron in
          connection with this Contract; and provided that Cogenron shall be
          required to mitigate any damages that it incurs as a result of such
          default, which mitigation obligation shall decrease the amount
          otherwise payable by UCC under this Section 18.2:

18.2.1    Cogenron may terminate the whole or any part of this Contract. In the
          event of such termination, Cogenron may discontinue steam

   16
          deliveries, refuse to receive Gas Service and disconnect and/or remove
          the Retrofit Equipment, after reasonable notice to UCC provided entry
          on UCC's Land is done in accordance with UCC's safety, security, and
          confidentiality requirements.

18.2.2    Cogenron may discontinue steam deliveries and refuse to receive Gas
          Service.

18.2.3    Cogenron may disconnect and/or remove the Retrofit Equipment, after
          reasonable notice to UCC provided entry on UCC's Land is done in
          accordance with UCC's safety and security requirements.

18.3      In the event that UCC cures any such default, Cogenron shall resume
          steam deliveries, receive Gas Service and continue its obligations
          under this Contract for the duration thereof.

                        Article 19 - Default of Cogenron

19.1      The following shall each constitute an Event of Default by Cogenron
          under this Contract:

19.1.1    Cogenron fails to perform any of the material provisions of this
          Contract or otherwise endangers performances of the Contract in
          accordance with its terms; and does not submit a proposed course of
          action within a period of thirty (30) days to correct such failure
          after failure of notice from UCC specifying such failure, and
          thereafter diligently proceeds to correct such failure; or

19.1.2    The occurrence of any of the following:

19.1.2.1  Cogenron's bankruptcy or insolvency or the initiation of any
          proceeding, voluntary or involuntary, against Cogenron. under the
          bankruptcy or insolvency laws, or Cogenron's failure to meet its debts
          in the ordinary course of business; provided, however, that there
          shall be no Event of Default if, within thirty (30) days from the

          Cogenron as debtor in possession or Cogenron's trustee, receiver,
          assignee or custodian, whichever is obligee under this Contract, in
          writing affirms this Contract, the Utility Service Agreement and the
          Lease and demonstrates to UCC's reasonable satisfaction the ability to
          fulfill its or their obligations under this Contract, the Utility
          Service Agreement and the Lease.

19.1.2.2  Cogenron makes an assignment of all or a substantial part of
          Cogenron's Plant or Cogenron's Land for the benefit of creditors.

19.2      UCC may, at its sole option, in the event of an occurrence of an Event
          of Default as defined in Section 19.1, exercise any or all of the
          following remedies by written notice of default to Cogenron, which
          shall constitute the sole and exclusive remedies available to UCC in
          connection with this Contract; and provided that UCC shall be required
          to mitigate any damages that it incurs as a result of such default,
          which mitigation obligation shall decrease the amount otherwise
          payable by Cogenron under this Section 19.2:

19.2.1    UCC may terminate the whole or any part of this Contract. In the event
          of such termination UCC may discontinue Gas Service, refuse to

   17
          take steam deliveries and may require title to and possession of the
          Retrofit Equipment to be transferred to UCC at no cost to UCC with no
          liens or other security interests attached.

19.2.2    UCC may require Cogenron to promptly assign, in whole or in part, its
          rights and obligations under each of its gas supply contracts that
          provide for the supply of gas to Cogenron's Plant for a portion of Gas
          equivalent on a BTU basis to the maximum steam taken provided under
          this Contract; provided, however that in the event that the occurrence
          of an Event of Default is caused by an insufficient gas supply, then
          Cogenron will exert its best efforts to cause assignment of such gas
          supply contracts to UCC.

19.3      In the event that Cogenron cures any such default, UCC shall resume
          Gas Service, receive steam deliveries and continue under this Contract
          for the duration thereof.

          Point of Delivery as practicable. Where electricity or instrument air
          is required for the operation of Cogenron's meters or meter regulating
          valves, Cogenron shall furnish and install wiring, piping and
          equipment necessary to provide such items. Notwithstanding any other
          provision of this Contract, maintenance and repair of such wiring,
          piping and equipment shall be Cogenron's obligation.

20.3      All UCC's security, safety, and confidentiality requirements shall be
          followed, and Cogenron shall exercise reasonable care to not damage or
          cause loss to UCC's Plant.

                     Article 21 - Access to Cogenron's Land

21.1      UCC shall have the right of access to Cogenron's Land, and on all
          other premises with respect to which Cogenron has secured easements in
          connection with this Contract, at all reasonable limes, for the
          purpose of inspecting Cogenron's Plant and inspecting the Gas Service
          lines, meters and equipment, removing its property, or any other
          proper purpose; provided that any such inspection shall not relieve
          Cogenron of its obligation to maintain Cogenron's Plant and the Gas
          Service lines, meters and equipment as provided in this Contract. All
          Cogenron's security and safety requirements shall be followed, and UCC
          shall exercise reasonable care to not damage or cause loss to
          Cogenron's Plant.

   18
22.1      It is further agreed that UCC and Cogenron as the case may be, shall
          indemnify and hold harmless the other party, and its directors,
          officers, employees, heirs, executors, successors and assigns from and
          against any and all loss, cost, expense, damages, liability, demands,
          claims, actions or causes of action (including the respective
          employees and agents of Cogenron and UCC, and third parties), or
          damage to or the loss of property (including but not limited to
          reasonable attorney's fees) for injury or death of persons (including
          the respective employees and agents of Cogenron and UCC, and third
          parties) or damage to or the loss of property of customer, company,
          and third parties) to the extent caused by, or arising out of, or
          resulting from any act, error, omission or negligence (including the
          failure to comply with any applicable regulations as required herein)
          or vicarious or strict liability of the indemnifying party in
          connection with the design, installation, operation or maintenance of
          the property and equipment of the parties hereto as required herein,
          the steam deliveries and/or Gas Service. It is thus intended that each
          party hereto shall be liable, as between the parties hereto, in the
          percentage that such party was the cause of any such loss, cost, etc.
          This section is intended to satisfy the express negligence test as set
          forth by the Texas Supreme Court. Therefore, the parties agree to
          indemnify each other for the consequences of their own negligence.

          IN WITNESS WHEREOF, this Agreement is signed and executed as of the
date and year written below.
