                         BASIC RIGHTS AND OBLIGATIONS

3.1   General. Subject to the terms and conditions set forth in this Agreement 
      and commencing with the Date of Initial Commercial Operation, the Parties
      agree that:

      A.  Buyer agrees to purchase from Seller 35,000 pounds per hour of 
          Deliverable Steam averaged on an annualized basis during all times
          that Seller has a minimum of 50,000 pounds per hour of Deliverable
          Steam available for Buyer. The calculation period for the annual
          average shall be from November 1 through October 31. The 35,000 pound
          per hour average is based on Buyer's current operation and steam
          demand and may be modified as provided for in Article 3.2.

      B.  Buyer agrees to advise Seller in advance of its desire to purchase 
          Deliverable Steam in excess of 50,000 pounds per hour, which Seller is
          not obligated to supply under this Agreement.


 
                                                                           ..4..
      C.  Seller agrees to use best efforts to advise Buyer of changes in 
          Deliverable Steam availability.

      D.  Buyer agrees that Seller has obligations and rights to supply steam to
          IMTT-Bayonne and electricity to Jersey Central Power & Light Company,
          which obligations and rights come before any right Buyer may have
          under this Agreement to receive Deliverable Steam from Seller except
          that Seller shall not provide steam to IMTT-Bayonne during any hour in
          excess of 57,000 pounds per hour, unless Seller has first made
          available during such hour 50,000 pounds per hour to Buyer under this
          Agreement.

3.2   Annualized Average Calculation.

      A.  Any hour that Seller does not have at least 50,000 pounds per hour of 
          Deliverable Steam available for Buyer shall be excluded from the
          annual average calculation. Any steam purchased by Buyer from Seller
          during any such hour shall also be excluded from the annual average
          calculation. If this occurs between September 1 and May 31 of any
          year, then Buyer shall be credited for 15,000 pounds for each hour of
          unavailability. At Buyer's discretion, the provisions of this
          paragraph may be waived with written notice to Seller within thirty
          (30) days of the date of such waiver so long as such waiver applies to
          each of the foregoing provisions of this paragraph (3.2A).

      B.  Any hour that Buyer's steam demand, including sales by Buyer, is under
          75,000 pounds per hour shall also be excluded from the annualized
          average calculation, along with any steam purchase by Buyer from
          Seller during the same period. If this occurs between September 1 and
          May 31 of any year, then Buyer shall also be credited for 15,000
          pounds for each such hour as provided herein (3.2B).

      C.  The 35,000 pound per hour annual average is based on Buyer's 1986 
          actual and projected steam demand for its operation, including outside
          sales. Buyer shall have the right to reduce the 35,000 pound per hour
          annual average to the extent that Buyer demonstrates that there are
          changes in Buyer's operation, including outside sales, which will
          result in lower annual steam requirements, provided, however, that in
          such event, Seller's 50,000 pounds per hour minimum Deliverable Steam
          obligation shall be reduced on a pro rata basis. (See Appendix C.)
          Such right may be exercised no earlier than sixty (60) days after
          Buyer presents supporting documentation to Seller.


 
                                                                               5


                                   ARTICLE 4
                                        
                                 SALE OF STEAM

4.1  Scheduling. Commencing with the Date of Initial Commercial Operation and
     thereafter during the term of this Agreement, Buyer shall give Seller its
     best estimate of its expected steam requirements for the next calendar
     year, at least by September 24 of the preceding calendar year.

     At least thirty (30) days in advance, Seller shall notify Buyer of any
     planned outages which will result in an interruption of steam deliveries to
     Buyer.

4.2  Buyer's Furnishing Steam to Seller. In the event that Seller is unable to
     produce steam at the Cogeneration Facility, by reason of Force Majeure,
     Buyer may, at its sole option, supply Seller with steam subject to the
     terms of this Article 4.2 so that Seller may fulfill its obligation to
     furnish steam to third parties. Seller shall verbally notify the Buyer's
     Shift Superintendent as soon as practical of the time at which Seller
     requests to receive steam from Buyer. Such verbal notice to be confirmed in
     writing within two (2) days, shall include the following:

      (i) an estimate of the period during which Seller expects to request steam
          from Buyer; and

     (ii) the amount of steam that Seller desires from Buyer.

     Steam purchased from Buyer by Seller shall be measured, billed and
     collected in the same manner provided for tales by Seller to Buyer under
     this Agreement. Pricing basis shall be per Appendix A plus ten percent.
     Buyer's decision to supply steam to Seller shall be conditioned upon the
     following:

      (i) any sale of steam to Seller under this Article 4.2 shall not interfere
          with Buyer's normal operations; and

     (ii) any sale of steam to Seller under this Article 4.2 shall not result
          in any liability to Buyer.

4.3  Monthly Steam Charge. Buyer shall pay Seller a Monthly Steam Charge which
     shall be equal to the steam charge calculated according to Appendix B,
     subject to adjustment in order according to Article 4.4.

 
                                                                               6

4.4  Adjustment to Monthly Steam Charge. The following adjustments may apply to
     the calculations made in Article 4.3 and shall be made in the order listed:

     A.  If the price per thousand pounds of Deliverable Steam as calculated in
         Appendix B is not at least $0.50 less then the incremental cost of
         steam calculated in Appendix A, then Seller's price shall be adjusted
         by Seller to be $0.50 less than the incremental cost as calculated in
         Appendix A.

     B.  If the steam delivered by Seller fails to conform to the specifications
         for steam contained in Article 1.8 for more than one hour after Seller
         has been notified by Buyer of such non-conforming deliveries, then

          (i) Buyer may, at its sole option, continue to accept delivery of
              steam to the extent usable by it, and

         (ii) the Monthly Steam Charge shall be reduced in proportion to the
              extent that the steam taken by Buyer falls short, as determined on
              a Btu basis, of the specifications for Deliverable Steam in
              Article 1.8.

4.5  Recalculation of Price. Buyer reserves the right to convert, at its sole
     option, Buyer's Steam Producing Facilities to fuels other than low sulfur
     fuel oil. Buyer shall provide Seller with written notice of such
     conversion a minimum of 120 days prior to converting to an alternate fuel.
     Within ninety (90) days prior to the conversion, the Parties will establish
     the Monthly Steam Charge per Article 4.3.

                                   ARTICLE 5
                                        
                    OTHER  RIGHTS AND OBLIGATIONS OF PARTIES

5.1  Other Rights and Obligations of Seller.

     In addition to other rights or obligations of Seller specified in this
     Agreement, Seller shall:

         for purposes; of sales to IMTT-Bayonne under the terms and conditions
         of the Agreement between Cogen Technologies NJ, Incorporated ("Seller")
         and IMTT-Bayonne ("Buyer") for the Sale of Steam and Electricity from a
         Cogeneration Plant, dated June 13, 1985, as amended as of May 22, 1986;
         to produce electric energy to

         Company, dated October 29, 1985, as may be amended, and to put its
         obligations and rights under those agreements ahead of its obligations
         to the Buyer under this Agreement except that Seller shall not provide
         steam to IMTT-Bayonne during any hour in excess of 57,000 pounds per
         hour, unless Seller has first made available during such hour 50,000
         pounds per hour to Buyer under this Agreement.


     B.  Have the right to sell any and all steam produced at the Cogeneration
         Facility and not purchased by Buyer pursuant to this Agreement to any

     C.  Corrections of Steam Measuring Equipment. If, upon testing, any steam
         measuring equipment is found to be in error by not more than plus or
         minus one-half of one percent (1/2%) at a flowrate corresponding to
         the average hourly flow rate for the period since the last preceding
         test, previous recordings of such equipment shall be considered
         accurate in computing deliveries of steam hereunder, but such equipment
         shall be promptly adjusted to record correctly. If, upon testing, any
         steam measuring equipment shall tie found to be inaccurate by an amount
         exceeding plus or minus one-half of one percent (1/2%) at a flowrate
         corresponding to the average hourly flowrate for the period since the
         last preceding test, then such equipment shall be promptly adjusted to
         record properly and any previous recordings by such equipment shall be
         corrected to zero error. If no reliable information exists as to when
         the equipment became inaccurate, it shall be assumed for correction
         purposes hereunder that such inaccuracy began at a point in time midway
         between the testing date and the last previous date on which the
         equipment was tested and found to be accurate.

6.6  Maintenance. Each Party shall have the right to be present whenever the
     other Party reads, cleans, changes, repairs, inspects, tests, cali-

                            ARBITRATION OF DISPUTES

15.1  Notice. In the event a dispute arises between the Parties with respect to
      the interpretation of, or performance under, this Agreement, either Party
      may give notice in writing to the other of its desire to submit such
      dispute to arbitration. Within forty-five (45) days after the receipt of
      such notice by the other Party, the Parties shall appoint a single
      arbitrator, from a list of eight obtained from the American Arbitration
      Association. If the Parties fail to agree on an arbitrator within ten (10)
      days, either Party may request the American Arbitration Association to
      appoint an arbitrator. An arbitrator so appointed shall have full
      authority to act pursuant to this Article. Nothing herein shall require
      arbitration of the disputes described above if either Party does not agree
      to such arbitration; however, both Parties shall be bound to arbitrate
      as soon as hearings have commenced pursuant to Article 15.2 below.

15.2  Arbitration Procedures. Within fifteen (15) days of his or her
      appointment, the arbitrator so appointed shall commence hearings on the
      dispute at such reasonable time and place in New Jersey as shall be
      established by the arbitrator. The then current rules of the American
      Arbitration Association for the conduct of commercial arbitration
      proceedings shall govern the conduct of such hearings and the resolution
      of the dispute, except that if such rules shall conflict with the then
      current laws of the State of New Jersey relating to arbitration, the laws
      of New Jersey shall govern.

15.3  Decision. The arbitrator shall fix a reasonable time after completion of
      the hearing within which the Parties shall make their final submissions of
      their respective positions and shall make his decision within thirty (30)
      days after such submissions, unless, for good cause to be certified by him
      in writing, he shall extend such time. The decision of the arbitrator
      shall be rendered in writing and in duplicate, and

 
                                                                              18

      one copy shall be delivered promptly to each Party. The award of the
      arbitrator shall be final except as otherwise provided by applicable law.
      Judgment upon such award may be entered on behalf of the prevailing Party
      in any court having jurisdiction thereof, and application may be made by
      such Party to any such court for judicial acceptance of such award and an
      order of enforcement.

15.4  Expenses. The expenses of arbitration shall be borne equally by both
      Parties.

      B.  Failure by Buyer or Seller to perform fully any other provision of
          this Agreement, or a breach of this Agreement by either Party, which
          failure or breach continues for a period of thirty (30) days after
          notice of such nonperformance or breach;

      C.  If by order of a court of competent jurisdiction, a receiver or
          liquidator or trustee of either Party or of any of the property of
          either Party shall be appointed, and such receiver or liquidator or
          trustee shall not have been discharged within a period of sixty (60)
          days; or if by decree of such a court, a Party shall be adjudicated
          bankrupt or insolvent or any substantial part of the property of such
          Party shall have been sequestered, and such decree shall have
          continued undischarged and unstayed for a period of sixty (60) days
          after the entry thereof; or if a petition to declare bankrupt or to
          reorganize a Party pursuant to any of the provisions of the Federal
          Bankruptcy Act, as it now exists or as it may hereafter be amended, or
          pursuant to any other similar state statute applicable to such Party
          as now or hereafter in effect, shall be filed against such Party and

          petition against it under any similar law; or, without limitation of
          the generality of the foregoing, if a Party shall file a petition or
          answer or consent seeking relief or assisting in seeking relief in a
          proceeding under any of the provisions of the Federal Bankruptcy Act,
          as it now exists or as it may hereafter be amended, or pursuant to any
          other similar state statute applicable to such Party, as is now or
          hereafter in effect, or an answer admitting the material allegations
          of a petition filed against it in such a proceeding; or if a Party
          shall make an assignment for the benefit of its creditor; or if a
          Party shall admit in writing its inability to pay its debts generally
          as they become due; or if a Party shall consent to the appointment of
          a receiver or receivers, or trustee or trustees, or liquidator or

16.2  Remedies for Breach. In the event of a breach of this Agreement, the non-
      breaching Party may terminate this Agreement upon written notice to the
      other Party, and may avail itself of any other remedies provided by law.

      terminated, neither Party shall refuse to make, suspend or delay any of
      the payments required under this Agreement as a result of any breach or
      alleged breach by the other Party.

16.4  Waiver of Breach. Either Party may waive breach by the other Party,
      provided that no waiver by or on behalf of either the Buyer or Seller of
      any breach of any of the covenants, provisions, conditions, restrictions
      or stipulations contained in this Agreement shall take effect or be
      binding on the Buyer or Seller unless the waiver is reduced to writing
      and executed by the Buyer or Seller, and any such waiver shall be deemed
      to extend only to the particular breach waived and shall not limit or
      otherwise affect any rights that the Buyer or Seller may have with respect
      to any other or future breach.

16.5  Notice to Financiers and Opportunity to Cure.

      A.  Buyer shall look only to Seller or to any successor of Seller under
          Article 20 to satisfy all obligations hereunder. No Financier shall
          have any obligation to satisfy any obligation or indebtedness of
          Seller to Buyer, except the obligations and indebtedness of Financier
          to Buyer required under the terms of this Agreement.

      B.  Notwithstanding the provisions of Article 16.5A, a Financier shall be
          liable to the Buyer for the uninsured liabilities only to the extent
          such liabilities represent defaults or breaches hereunder

 
                                                                              20

          caused by Financier's actions. Financier's liability to the Buyer for
          uninsured liabilities which have not been caused by Financier's
          actions shall be limited to the extent of such Financier's interest in
          the Cogeneration Facility. However, if financier exercises his rights
          under Article 16.5C, this limitation shall no longer be applicable.

      C.  Seller shall promptly notify the Buyer of the names and addresses of
          all Financiers. Buyer shall not terminate this Agreement until it has
          given thirty (30) days' written notice of any breach thereof to each
          of such Financiers, and Buyer hereby agrees to promptly notify all
          Financiers of any breach. If Buyer fails to give such notice, Buyer
          shall not be liable for damages to any Financier as a result of such
          failure, but any termination of this Agreement shall be of no force
          and effect. Thereafter, Buyer shall not terminate this Agreement as a
          result of any such breach if within such thirty (30) day period any
          Financier has either:

           (i)  cured the breach if it can be cured by payment of money; or

          (ii)  if the breach cannot be so cured, caused the initiation of and
                is diligently pursuing proceedings to give the Financier
                possession of the Cogeneration Facility, or has diligently
                commenced to cure the breach, and for so long as the Financier
                diligently continues such efforts.

      D.  If a Financier is prohibited from curing such breach by any of the
          following proceedings,

          1. any process or injunction issued by any court,

          2. any action by any court having jurisdiction over any bankruptcy or
             insolvency proceeding involving the Seller, or

          3. any automatic stay issued by a court referred to in Article 16.5D2
             above,

          the time specified above in Section 16.5C shall be extended for the
          period of such prohibition.

      E.  Nothing in this Agreement shall require a Financier to cure any
          default hereunder in advance of entering the Cogeneration Facility
          with the purpose of continuing to operate the Cogeneration Facility.
          Actions by a Financier against the Cogeneration Facility under a
          mortgage or other security right or encumbrance shall not in
          themselves be deemed an election by Financier to assume Seller's
          obligations hereunder.

remedies under the Assigned Agreements including the right to receive any and
all moneys due or to become due thereunder.

          2.4 It is hereby expressly agreed that, anything contained herein to
the contrary notwithstanding, the Borrower shall remain liable under the
Assigned Agreements to perform all the obligations assumed by it thereunder and
the Secured Party shall not have any obligation or liability thereunder by
reason of or arising out of the assignments herein contained, nor shall the

obligations of the Borrower under the Assigned Agreements or pursuant thereto,
or to make any payment, or, unless and until indemnified to its satisfaction, to
present or file any claim, or to take any other action to enforce any right
assigned to it hereunder or to which it may be entitled pursuant hereto at any
time or times.

attorney-in-fact to do in its name all acts which it could do in relation to the
Assigned Agreements and in particular, but without limiting the generality of

endorse any checks or other instruments or orders in connection therewith and to
file any claims or to take any action or institute any proceedings which the
Secured Party may deem to be necessary or advisable in the circumstances, which
appointment is coupled with an interest. Except insofar as necessary to effect
compliance with the provisions of Section 4.04(c) of the Loan Agreement, the
Secured Party shall not exercise any of the powers granted pursuant to the
foregoing sentence until the earliest of the breach of the Borrower's
obligations hereunder or under any other Security Document or the occurrence of
an Event of Default under the Loan Agreement.

          2.8 If an Event of Default shall have occurred and be continuing, the
Secured Party may exercise with respect to the Assigned Property those rights
set forth in Section 3 hereof.

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

3.1  General
     -------

     (A)  Paragraph A. of Article 3.1 of the February Agreement is amended to
          read as follows:

 
          A.  Buyer agrees to purchase from Seller 50,000 pounds per hour of
              Deliverable Steam averaged on an annualized basis during all times
              that Seller has a minimum of 65,000 pounds per hour of Deliverable
              Steam available for Buyer. The calculation period for the annual
              average shall be from November 1 through October 31. The 50,000
              pound per hour average is based on Buyer's current operation and
              steam demand and may be modified as provided for in Article 3.2.

     (B)  Paragraph B. of Article 3.1 of the February Agreement is amended to
          read as follows:

          B.  Buyer agrees to advise Seller in advance of its desire to purchase
              Deliverable Steam in excess of 65,000 pounds per hour, which
              Seller is not obligated to supply under this Agreement.

     (C)  Paragraph D. of Article 3.1 of the February Agreement is amended to
          read as follows:

          D.  Buyer agrees that Seller has obligations and rights to supply
              steam to IMTT-Bayonne and to ICI Americas, Inc., and electricity
              to Jersey Central Power & Light Company, which obligations and
              rights come before any right Buyer may have under this Agreement
              to receive Deliverable Steam from Seller except that Seller shall
              not provide steam during any hour to IMTT-Bayonne in excess of
              57,000 pounds per hour nor to ICI Americas, Inc., in excess of
              20,000 pounds per hour, unless Seller has first made available
              during such hour 65,000 pounds per hour to Buyer under this
              Agreement.


3.2  Annualized Average Calculation
     ------------------------------

     (A)  Paragraph A. of Article 3.2 of the February Agreement is amended to
          read as follows:

          A.  Any hour that Seller does not have at least 65,000 pounds per hour
              of Deliverable Steam available for Buyer shall be excluded from
              the annual average calculation. Any steam purchased by Buyer from
              Seller during any such hour shall also be excluded from the annual
              average calculation. If this occurs between September 1 and May 31
              of any year, then Buyer shall be credited for 15,000 pounds for
              each hour of unavailability. At Buyer's discretion, the provisions
              of this paragraph may be waived with written notice to Seller
              within thirty (30) days of the date of such waiver so long as such
              waiver applies to each of the foregoing provisions of this
              paragraph (3.2A).

     (B)  Paragraph C. of Article 3.2 of the February Agreement is amended to
          read as follows:

 
          C.  The 50,000 pound per hour annual average is based on Buyer's
              1987 actual steam demand for its operation, including outside
              sales. Buyer shall have the right to reduce the 50,000 pound per
              hour annual average to the extent that Buyer demonstrates that
              there are changes in Buyer's operation, including outside sales,
              which will result in lower annual steam requirements, provided,
              however, that in such event, Seller's 65,000 pounds per hour
              minimum Deliverable Steam obligation shall be reduced on a pro
              rata basis. (See Appendix C.) Such right may be exercised no
              earlier than sixty (60) days after Buyer presents supporting
              documentation to Seller.


                                   ARTICLE 4
                                   ---------

4.1  Adjustment to Monthly Steam Charge
     ----------------------------------

     Paragraph A. of Article 4.4 of the February Agreement is amended to read as
     follows:

          A.  If the price per thousand pounds of Deliverable Steam as
              calculated in Appendix B is not at least $0.50 less than the
              lowest incremental cost of steam calculated in Appendix A, then
              Seller's price shall be adjusted by Seller to be $0.50 less than
              the lowest incremental cost as calculated in Appendix A.


4.2  Recalculation of Price
     ----------------------

     Article 4.5 of the February Agreement, regarding recalculation of price, is
     deleted.

                                   ARTICLE 5

Calculation of ETIC
- -------------------

Exxon's incremental cost of steam for purposes of Article 4.4A is the lowest of
ETIC\Oil\ or ETIC\Gas\, where ETIC\Oil\ = EIFC\Oil\ + EIWC + EICC and ETIC\Gas\
= EIFC\Gas\ + EIWC + EICC. The formulas for both ETIC\Oil\ and ETIC\Gas\ shall
be calculated on a monthly basis by Seller in $/klb.

Sample Calculation
- ------------------

PAP  = $18.50 per barrel
BWP  = $21.00 per kcuft
EICC = $ 0.15 per klb
AF   = $ 2.87 per MBtu


EIFC\Oil\ = 0.23   * $18.50 = $4.26

EIWC      = 0.0172 * $21.00 = $0.36

EICC      = 0.15            = $0.15
                              -----
ETIC\Oil\ =                   $4.77

EIFC\Gas\ = 1.4592 *  $2.87 = $4.19

EIWC      = 0.0172 * $21.00 = $0.36

EICC      = 0.15            = $0.15
                              -----
ETIC\Gas\ =                 = $4.70

The cost of steam from Appendix A to be used in determining whether an
adjustment to the monthly steam charge is appropriate pursuant to Article 4.4A
shall be the lower of (ETIC\Oil\ - $.50) or (ETIC\Gas\ - $.50) (ie., under
Sample Calculation, cost of steam from Appendix A = $4.70 - .50 = $4.20/klb).
