   through the Transfer Date, Partnership, using ENI employees, shall turn off
   the Facility's LM Gas Turbines and shall turn on and operate all five (5)
   of the HSC boilers described in the Relevant Documents in order to supply
   steam to HSC as if the Steam Supply Agreement were still in effect.

   boilers as set forth in the Steam Supply Agreement.  Seitel Gas and Energy
   Corp. has been nominated by Partnership to provide gas for all of the
   Project requirements related to the production of steam for HSC until the
   Transfer Date, and Partnership shall pay for such gas.  Partnership will
   utilize Connecticut Natural Gas for the transportation of gas at the

               (b)  Partnership shall cause Operator, within fifteen (15) days

               (c)  Partnership shall remove, or cause to be removed, the LM
   Gas Turbines from the Demised Premises (as defined in the Mortgage) and
   shall inform HSC of the location of such LM Gas Turbines.

   ENI, HSC and Connecticut Natural Gas shall be Donald Ludington, and the

   Prior to commencement of demobilization, Partnership shall cause each
   contractor performing work thereon to designate a spokesperson to
   Partnership and ENI.
    
               (e)  Prior to commencement of demobilization, Partnership shall
   cause Operator to inform ENI of the number and names of ENI employees
   needed to assist in the demobilization and the anticipated periods of time
   during which their assistance will be required.  Partnership shall
   reimburse ENI for all costs incurred by ENI as to such employees for the
   time during which they are assisting with the demobilization and during
   which they are operating the HSC boilers for the account of Partnership. 
   Such reimbursement shall be calculated on the same basis as it was under
   the Relevant Documents before such documents were terminated.
    
               SECTION 4.02.  OPERATING EXPENSES.  Until the Transfer Date,
   Partnership shall reimburse HSC for the reasonable cost of ordinary
   electricity use by Partnership in connection with the operation of the
   boilers and shall continue to pay to HSC, ENI and Connecticut Natural Gas
   their respective charges for use of employees, fuel, river water, etc. as


   provided in the Steam Supply Agreement, and HSC shall continue to pay
   Partnership for the steam described in Section 4.01(a) as provided in the
   Steam Supply Agreement; provided, however, that Partnership hereby directs
   HSC to transmit to ENI and Connecticut Natural Gas any sums due ENI or
   Connecticut Natural Gas for the account of Partnership; to setoff any
   amounts due to HSC from Partnership against payments due from HSC to
   Partnership; and to pay to Partnership only such amounts as remain after
   such directed payments and setoffs.  If the amount of such directed
   payments and setoffs are less than the amounts owed by Partnership to HSC,
   ENI or Connecticut Natural Gas, Partnership shall pay such amounts within
   ten (10) days after a written invoice therefor.  If the amount of such
   directed payments and setoffs are less than the amounts owed to Partnership
   by HSC, HSC shall pay such amounts within ten (10) days after a written
   invoice therefor.
    
               SECTION 4.03.  PROPERTY TAXES.  (a)  Partnership will pay all
   personal property taxes to the City of Hartford for all periods before and
   after the Closing with respect to all personal property retained by
   Partnership and not transferred to HSC pursuant to the Bill of Sale and the
   Quitclaim Deeds, and HSC will have no responsibility for any such taxes.  
    
               (b)  Partnership will pay personal property taxes to the City
   of Hartford with respect to the property transferred to HSC or ENI pursuant
   to the Bill of Sale and the Quitclaim Deeds for all periods through June
   30, 1995, and thereafter property taxes to the City of Hartford on such
   property shall be adjusted after the Closing, but as of the Closing Date,
   between Partnership and HSC in the manner customary for the adjustment of
   real property taxes in the City of Hartford.  The parties agree that for
   purposes of such adjustment, the value to be used in respect of such
   personal property transferred to HSC or ENI pursuant to the Bill of Sale
   and the Quitclaim Deeds will be calculated based on good faith estimates of
   values of personal property transferred to HSC.
    
               (c)  Partnership shall remain responsible for all real property
   taxes to the City of Hartford for which it is currently responsible for all
   periods through June 30, 1995, and thereafter property taxes to the City of
   Hartford with respect to such real property shall be adjusted at the
   Closing as of the Closing Date between Partnership and HSC in the manner
   customary for the adjustment of real property taxes in the City of
   Hartford.
    
               SECTION 4.04.  ACCESS TO SITE.  (a)  ENI, HSC and Connecticut
   Natural Gas agrees to provide to Partnership and its agents, for no

   March 1, 1989; and
    
               (iv)  use of an area for temporary "laydown" purposes (but not


   storage) adjacent to and extending 25 feet north of the existing structure
   occupied by HSC and ENI in which the cogeneration facility is located, and
   ENI will cooperate with the Partnership's removal contractor to seek to
   locate additional laydown areas for use by the contractor.
    
               (b)   In connection with the rights specified in paragraph (a)
   above, Partnership agrees that:
    
               (i) the exercise of such rights shall be performed in a manner
   which will not obstruct access by ENI, HSC or Connecticut Natural Gas, as
   the case may be, to the relevant property or its property adjacent or
   contiguous to such property and in a manner which will cause the least
   practicable interference with such party's operations on such property or
   such adjacent or contiguous property;
    
               (ii) during the term of this Agreement and until completion of
   the removal and restoration activities provided for in Section 7.04 hereof,
   it shall keep in force and effect a public liability and property damage
   insurance with respect to its entry upon and conduct upon the Demised
   Premises insuring ENI, HSC or Connecticut Natural Gas, as the case may be,
   against liability to the same extent and in the manner set forth in Section
   9 of the Site Lease Agreement; and
    
               (iii) it agrees to indemnify and save ENI, HSC and Connecticut
   Natural Gas harmless from and against all liability or expense on account
   of any accident or injury to ENI, HSC and Connecticut Natural Gas or any
   other person or the property of ENI, HSC or Connecticut Natural Gas, as the
   case may be, or any other person as a result of or arising from entry into
   or activities upon the Demised Premises or the above access and laydown
   areas by the Partnership, its contractors, subcontractors, and its or their
   servants, agents, representatives or invitees and to repair any and all
   damage to property of ENI, HSC or Connecticut Natural Gas, as the case may
   be, caused by Partnership or resulting from or arising out of such entry.
    
               SECTION 4.05.  CERTAIN REMITTANCES.  Partnership agrees that
   within two business days of the Escrow Release Date (as defined in the

   Partnership any portion of the original principal amount of the Note that
   has been prepaid as of the Escrow Release Date.

   and agrees that, upon Partnership's request, it will prepare, within 24

   the release from the Mortgage of any collateral covered by the Mortgage
   that is sold or to be sold by Partnership in accordance with the terms of
   the Mortgage.  It agrees to execute and file such termination statements or
   releases with the appropriate authority or authorities immediately upon
   receipt of confirmation from Sumitomo that the sales proceeds have been
   deposited into escrow.  It further agrees to insure that appropriate
   officials will be available at Partnership's reasonable request to perform

                             Covenants of Partnership
                             ------------------------
    
               Partnership covenants and agrees that:
    
               SECTION 7.01.  GOVERNMENTAL APPROVALS AND OTHER CONSENTS.  It
   will use its best efforts, and will cause each of its Affiliates to use its
   best efforts, to obtain all governmental approvals and other consents


   necessary or appropriate to permit the consummation of the transactions
   contemplated by this Agreement and the other Termination Documents.
    
               SECTION 7.02.  NO ACTION UNDER RELEVANT DOCUMENTS.  (a)  Until
   the termination of this Agreement, it will neither exercise any remedies
   available to it nor take or omit to take, directly or indirectly, any
   action under any Relevant Document relating to any defaults or events of
   default thereunder existing or alleged to be existing as of the date of
   this Agreement or occurring during the term of this Agreement.
    
               (b)  In the event that the Closing Date shall not have
   occurred, it may, after the termination of this Agreement, exercise any
   remedies available to it under any Relevant Document in accordance with the
   terms, and relating to any events of default, thereunder (i) existing on or
   prior to the date of this Agreement or (ii) occurring during the term of
   this Agreement other than those (A) that have been waived and (B) arising
   out of acts or omissions occurring as a result of the implementation of
   this Agreement.
    
               SECTION 7.03.  EXECUTION OF SALE CONTRACT.  It will use
   reasonable commercial efforts to cause a contract ("Sale Contract") for the
   sale of the two LM 2500 Gas Turbines to be executed and delivered prior to
   Closing or as soon thereafter as practicable.
    
               SECTION 7.04.  REMOVAL OF CERTAIN EQUIPMENT AND RESTORATION OF
   PREMISES.  (a)  Not later than March 31, 1996, Partnership will cause all
   equipment, piping, controls and appurtenances not covered by either the
   Bill of Sale or the Quitclaim Deeds to be removed and disposed of, except
   for any such equipment, piping, controls or appurtenances that HSC and
   Partnership shall in good faith and in writing agree need not be removed
   and except for improvements to real property.  If the Partnership and HSC
   fail to mutually agree in good faith that a specific item of equipment,
   piping, control or appurtenance need not be removed, Partnership shall
   cause such item of equipment, piping, control or appurtenance to be
   removed.
    
               (b)  Removal work performed by Partnership will be done in
   accordance with good engineering practices, including appropriate
   restoration work and will be performed in a manner so as not to materially
   interfere with the operations of HSC, ENI or Connecticut Natural Gas.  Any
   remaining equipment, piping, controls or appurtenances will be left in a
   safe and unobtrusive condition and will be capped or terminated at existing
   valves at HSC's direction.  Removal and disposal of the gas fuel supply
   equipment and water treatment and boiler treatment chemicals or other
   similar chemicals used by Operator will comply with applicable law relating
   to hazardous waste.
    
               (c)  In order to effect the removal and restoration work
   described in this Section 7.04, the Partnership shall enter into an
   agreement with ESI, Inc. of Tennessee or other contractor satisfactory to
   HSC (hereinafter, "ESI") substantially in the form of Exhibit J hereto (the
   "Removal Contract").  HSC will be given a reasonable opportunity to review
   the Removal Contract before its execution.  The Removal Contract shall
   include, without limitation, pre-commencement of work waivers of mechanics
   liens by ESI, and requirements that ESI secure performance bonds that
   guaranty the completion of the Removal Contract and that provide for the
   bonding off within [48] hours of any mechanics liens filed by subcontractor
   of ESI on any of the properties of HSC, ENI or Connecticut Natural Gas.  No
   modifications shall be made to the draft Removal Contract that would
   materially impact HSC, ENI or Connecticut Natural Gas without the written


   approval of HSC.
    
               (d)  Partnership shall no later than the Transfer Date deposit
   $3.4 million into an escrow account to be managed by Shawmut Bank, N.A.,
   pursuant to an Escrow Agreement substantially in the form of Exhibit K
   hereto, to provide for the funding of the Removal Contract.  No funds shall
   be released from the escrow account to the Partnership until the Removal
   Contract has been fully performed.
    
               SECTION 7.05.  ACTIONS RELATING TO REMOVAL CONTRACT. 
   Substantially simultaneously with the execution and delivery of the Removal
   Contract and Escrow Agreement, Partnership shall execute and deliver a
   conditional assignment agreement substantially in the form attached hereto
   as Exhibit I (the "Assignment Agreement").

               SECTION 8.03.  AMENDMENTS.  This Agreement may not be amended,
   supplemented or otherwise modified, and no provision of this Agreement may
   be waived, except by a written instrument signed by each of the parties
   hereto.
    
               SECTION 8.04.  ASSIGNMENTS.  This Agreement shall be binding
   upon, and inure to the benefit of, each of the parties hereto and its
   successors and assigns, except that no party may assign or transfer any of
   its rights or obligations under this Agreement.
    
               SECTION 8.05.  SURVIVAL.  Notwithstanding any provision of any
   Relevant Document to the contrary, none of the representations, warranties,
   indemnities or other provisions of any Relevant Document nor the
   obligations of any party thereunder shall survive the consummation of the
   transactions contemplated by this Agreement.
    
               SECTION 8.06.  SURVIVAL AND NONINTEGRATION.  The parties hereto
   agree that this Agreement, the Bill of Sale from Partnership to HSC, the
   Note, the Mortgage and the Assignment Agreement, all of even date herewith,
   were executed with the intent that they be and remain effective after and
   are not integrated in the Release, and the obligations under each such
   document shall be unaffected by such Release.
    
               SECTION 8.07.  TERMINATION OF THIS AGREEMENT.  This Agreement
   shall terminate automatically if the Closing is not effected by September
   30, 1995, except that the provisions of Sections 6.03(b) and 7.02(b) shall
   survive the termination of this Agreement.
    
               SECTION 8.08.  NOTE AND MORTGAGE.  Immediately after the Note
   has been paid in full or otherwise satisfied or discharged, the terms and
   provisions of the Release shall thereafter apply to all rights and
   obligations the parties had or may have had under the Note and Mortgage as


   if such rights and obligations were expressly mentioned in such Release. 
   The parties hereto agree to prepare and file with the appropriate
   jurisdictions any necessary forms to effect the termination of the
   Mortgage.
    
               SECTION 8.09.  CONFIDENTIALITY.  Each of the parties hereto
   agrees not to disclose to any third person and to keep confidential, and to
   cause and instruct each of its Affiliates, officers, directors, employees
   and representatives not to disclose to any third person and to keep
   confidential, any and all information obtained by it relating to
   Partnership, any of its Affiliates or the Project; PROVIDED, HOWEVER, that
   any information may be disclosed (i) to the extent required by applicable
   laws and regulations or by any subpoena or similar legal process so long as
   Partnership is given written notice at least three business days prior to
   such disclosure or (ii) to the extent Partnership shall have consented in
   writing prior to any such disclosure, including, without limitation, with
   respect to the submission or disclosure of this Agreement or any of its
   terms to any governmental authority in connection with HSC's, ENI's and
   Connecticut Natural Gas' obligations hereunder.
    


               IN WITNESS WHEREOF, the parties hereto have caused this
   Agreement to be duly executed as of the day and year first above written.
