     Premises as an incident of the ownership thereof and which are of  the
     kind  customarily paid by owners of land and improvements  thereto  by
     reason of such ownership, it being the intention of the parties  that,
     during  the  Term, Tenant shall be chargeable with and shall  pay  all
     sums which an owner of the Demised Premises would Day having regard to
     the  safeguarding  of  its  investment and  the  preservation  of  the
     freehold.

        5.2     Subject to section 5.3 of this lease, Tenant agrees to  pay
each item of Additional Rent on or before the date when each becomes due or
when  billed for the same by Landlord, as applicable.  Tenant shall furnish

request Landlord shall provide Tenant with copies of all such real estate
and assessments bills at the time of billing and evidence of Landlord's
payment of the same.  If Tenant shall fail to make any payment or to do any

National Association, Now Jersey, plus 2% per annum, shall be deemed
Additional Rent payable by Tenant upon demand by Landlord.  The making of
any such payment or the doing of any such act by Landlord shall not
constitute a waiver by Landlord of any right or remedy provided by this
lease upon Tenant's default in the making of such payment or the doing of
such act.  All taxes, assessments, water rents and other governmental
charges assessed against or levied upon the Demised Premises shall be
apportioned between Landlord and Tenant at the Commencement Date and
Termination Date.

          proceedings or in any other manner permitted by law, at  Tenant's
          sole cost and expense, in Tenant's name and/or in Landlord's name

          bond  or  other  security  reasonably  satisfactory  to  Landlord
          against  any  liens by reason of such contest.   The  contest  by

          until  a  final nonappealable determination shall be  made  by  a
          court or governmental department or authority having jurisdiction
          in the matter.

5.4       No  payment  by Tenant or receipt by Landlord of a lesser  amount
          than  the Base Rent and Additional Rent stipulated in this  lease
          shall  be deemed other than on account of the earliest stipulated
          rent,  nor  shall any endorsement or statement an  any  check  or
          payment or any writing accompanying any check or payment of  such
          rent  be  deemed  an accord and satisfaction,  and  Landlord  may
          accept  such  check  or payment without prejudice  to  Landlord's
          right  to  recover the balance of such rent or pursue  any  other
          remedy provided in this lease.

5.5       If  Tenant  fails to make any payment o f Base Rent or Additional

monies then due and owing by Landlord to Tenant pursuant to the Agreement.

     6.   CHANGE IN SCOPE OR AMOUNT OF TAXATION.
        
6.1       If  at  any time during the Term the method or scope of  taxation
          prevailing  an  the  date hereof shall be  altered,  modified  or
          enlarged  so as to cause the method of taxation to be changed  in
          whole  or  in  part so that in substitution for the  real  estate
          taxes  now assessed there may be, in whole or in part, a  capital
          levy  or  other  imposition based on the  value  of  the  Demised
          Premises or the rents received therefrom, or some other  form  of
          assessment  based in whole or in part on some other valuation  of
          the  Landlord's  real property comprising the  Demised  Premises,
          then  the  substituted  tax or imposition shall  be  payable  and
          discharged by Tenant in the manner required pursuant to  the  law
          promulgated  which shall authorize the change  in  the  scope  of
          taxation  and  as  required by the terms and conditions  of  this
          lease.

     6.2   Nothing contained in this lease shall require Tenant to pay  any
franchise, estate, inheritance, succession, capital levy or transfer tax of
Landlord,  or  federal  income or state income tax  or  excess  profits  or
revenue tax or other tax based upon Landlord's income, except to the extent
(a)  such  taxes  are  imposed in whole or partial  substitution  for  real
property  taxes  and (b) Landlord's transfer taxes are  payable  by  Tenant
under section 39.
     
     6.3   If  any tax which Tenant is required to pay pursuant to sections
6.1  or 6.2 above is a graduated tax, Tenant shall be required to pay  only
the  portion  thereof  which would have been payable  by  Landlord  if  the
Demised Premises were the only real property owned by Landlord.
     
     6.4   Notwithstanding anything in this lease (except section  6.5)  to
the  contrary and pursuant to Article 12 of the Agreement, (a) Tenant shall
be  solely responsible for any sales, use, property, income or other  taxes
relating  to  the  Facility and its components  or  the  operation  of  the
Facility  and,  except  as  otherwise  provided  by  section  12.3  of  the
Agreement,  the sale of energy produced therein and (b) Landlord  shall  be
solely  responsible  for any sales, use, property, income  or  other  taxes
relating to Landlord's Plant (as that term is defined in Article 1  of  the
Agreement),  its  components or appurtenances or the sale of  the  products
produced therein.
     
                                     5



     6.5  Notwithstanding section 6.3, so long as single real estate tax
bills or bills for assessments attributable to the Entire Property of which
the Demised Premises are only a part are submitted during the term of this
lease by the municipal or other authorities having jurisdiction, Landlord
shall pay such bills to the appropriate authorities and Tenant shall be
responsible for (a) 9.1% of the land portion of such tax bills, or such
other prorated amount if the tax lot configurations are altered from their
present configuration, such latter amount to be calculated on the new
percentage that the Demised Premises is of the Entire Property following
such alteration, plus (b) 100% of the taxes attributable on such tax bills
to the buildings and improvements now or to be located within the Demised
Promises including, but not limited to, the Facility, plus (c) that portion
of any bills for assessments determined by multiplying the total amount of
any such bill by a fraction the numerator of which is the total amount of
Tenant's taxes computed in accordance with (b) above and the denominator of
which is the total amount of taxes attributable on such tax bills to all
buildings and improvements located within the Entire Property, including
the Demised Premises.  Landlord shall be responsible for 100% of the taxes
attributable on such tax bills to the buildings and improvements now or to
be located within that portion of the Entire Property not being leased to
Tenant hereunder.  If there is a dispute between the parties regarding the
amount of taxes attributable to. buildings and improvements located within
the Demised Premises, the parties agree that the attribution contained in
the records of the tax assessor of the City of Newark shall control.  If
such records do not contain the necessary attribution, such attribution
shall be determined by an independent M.A.I. appraiser selected by
Landlord.  Landlord shall bill Tenant for Tenant's share of all real estate
tax bills and bills for assessments and Tenant shall pay such bills as
Additional Rent within 10 days of its receipt of such bills.
     
     6.6   Landlord agrees (a) not to bill Tenant for installments of taxes
or  assessments  more than 30 days before the respective dates  upon  which
such installments are due and (b) to elect to pay all assessments which may
be  paid  in  installments in as many installments as shall be  permissible
under applicable law, except that Tenant agrees to pay any additional costs
or expenses incurred by Landlord as a result of such election.
     
     7.   INSURANCE.
     
     7. 1 Tenant shall keep the improvements on the Demised Premises
insured against loss or damage by fire
     
                                     6
     


and  risks  embraced within "all risk coverage" in the locality  where  the
Demised  Premises  are  located in an amount not less  than  100%  of  full
insurable  value.   The  term  "full  insurable  value"  means  the  actual
replacement cost as defined in the standard "replacement cost" endorsement.
Tenant  shall  also obtain boiler explosion and casualty  insurance  in  an
amount  not  less  than ten million dollars ($10,000,000).   All  insurance
policies  shall be issued by a company or companies and in a form or  forms
reasonably  satisfactory  to  Landlord and  shall  name  Landlord  and  any
mortgagees of both Tenant and Landlord as additional insureds but not  loss
payees.   Tenant  agrees to use any proceeds received  from  the  insurance
policies   to   repair,  restore,  replace  and/or  rebuild   any   damaged
improvements on the Demised Premises so that the fair market value  of  the
Demised  Premises will not be decreased from that prevailing prior  to  the
casualty,  except as otherwise provided in either section 13 of this  lease
or  in the Construction and Term Credit Agreement dated as of July 18, 1988
between  Tenant  and  National Westminster Bank PLC,  including  only  such
amendments which may be made from time to time with the consent of Landlord
("Credit Agreement").
     
     7.2   Tenant  shall  obtain  and maintain a  Landlord's  and  Tenant's
comprehensive general Public Liability Insurance Policy for the  joint  and
several  benefit  of  Landlord and Tenant,  in  an  amount  not  less  than
$5,000,000.  Tenant shall also obtain blanket contractual insurance  in  an
amount  deemed  adequate by Landlord to cover the indemnity obligations  of
Tenant  pursuant to all of the terms and provisions of both this lease  and
the  Agreement.  Tenant shall provide and keep in force insurance for  such
other  insurable hazards and in such amounts as similarly situated premises
are then commonly insured.

     7.3   Prior  to the earlier of (a) the Commencement Date  or  (b)  the
date  when  Tenant  has  access to the Demised Premises  for  any  purpose,
Tenant  shall deliver to Landlord certificates evidencing the  issuance  of
each  of  the policies required by sections 7.1 and 7.2 and also evidencing
that  the  policies  are  then in effect.  Tenant  shall  deliver  original
insurance policies to Landlord within 15 days from the date when Tenant  is
required  to  deliver  the  certificates.   All  insurance  policies  shall
provide  for  30  days  advance notice in writing to Landlord  and  to  the
respective  mortgagees  of  Tenant or Landlord  prior  to  cancellation  or
modification.

     7.4  The premiums on any insurance policies which Landlord elects to
keep in force beyond the Termination Date shall be apportioned as between
Landlord and Tenant

                                     7



in  such  manner  that Landlord shall reimburse Tenant for  that  pro  rata
portion  of  the  unearned premiums on any policies which remain  in  force
beyond the Termination Date as a result of Landlord's election.

     7.5   Neither Landlord nor its agents or servants shall be liable  and
Tenant  waives all claims for damage, regardless of the cause  thereof,  to
persons  or  property sustained by Tenant, its agent and  servants  or  any
occupant of the Demised Premises resulting from the Demised Promises or any
part thereof or any part or any equipment or appurtenances becoming out  of
repair,  or resulting from any accident in on or about the Demised Promises
or  resulting directly or indirectly from any act or neglect of the  Tenant
or  occupant  or any other person including Landlord's agents and  servants
other than such injury or harm as may be caused solely and conclusively  by
the fault or negligence of Landlord, its directors, officers, employees  or
representatives.  All property belonging to Tenant or any occupant  of  the
Demised  Promises shall be there at the risk of the Tenant  or  such  other
person  only  and Landlord shall not be responsible or liable  for  damages
thereto  or  misappropriation thereof.  Except  as  otherwise  provided  in

Landlord agrees to look solely to the proceeds of its own insurance for
indemnity against personal injury, casualty loss and business interruption.
     
     7.7   Each  party  will use its best efforts to cause  each  insurance
policy  carried  by it with respect to the Entire Property or  the  Demised
Premises,  as applicable, to be written so as to provide that  the  insurer
waives all right of recovery by way of subrogation against the other  party
in connection with any loss or damage covered by the policy.
     
     7.8   Every  2  years  during  the Term  on  the  anniversary  of  the
Commencement Date, Landlord shall have the right to give Tenant notice that
Landlord is requiring Tenant to increase the amount of coverage under  each
insurance  policy  held by Tenant in connection with its operation  of  the
Facility.   The  maximum new insurance coverage amount which  Landlord  can
require for each policy shall be calculated by multiplying the total amount
of  insurance coverage in effect as of the Commencement Date by a fraction,
the  Numerator of which is the Consumer Price Index for Urban Wage  Earners
and Clerical Workers

                                     8



for  New  York  -  Northeastern New Jersey ("CPI") as of  the  day  of  the
applicable  2-year anniversary date and the denominator Of I which  is  the
CPI  as  of the Commencement Date. (For example, if the CPI is 200  on  the
Commencement  Date  and  220  on the first day  of  the  applicable  2-year
anniversary date, the new amount of insurance required would be  determined
as follows: 220 X Insurance Amount as of the Commencement Date.)
            220
in  no event shall the amount of insurance coverage for any policy decrease
in any 2-year period from that payable for the prior 2-year period.

          new lease with that person, firm or corporation on the same terms

          new  lease unless and until that person, firm or corporation  has
          (a)  cured  all  of Tenant's defaults, if any, under  this  lease
          which  are capable of being cured and (b) has agreed to  pay  all

          latter   case   the  mortgagee  shall  diligently  prosecute   to
          conclusion  all  acts  necessary to cure the  Event  of  Default.

          without further notice to the mortgagee.  The Lease Term  may  be
          preserved if the mortgagee within the cure periods set  forth  in
          this  section (a) cures all monetary defaults hereunder and under
          the Agreement, (b) cures any default under section 16.2(i) of the

same  by condemnation, eminent demain or otherwise, the amount awarded  for
compensation for the whole of the Demised Premises so taken shall  be  paid
to  Landlord.   Tenant  hereby expressly grants unto  Landlord  the  entire
amount of the award or compensation, expressly disclaiming all right, title
and interest therein, and agrees that it shall have no claim for any damage
or  loss  against Landlord by reason of the condemnation or  taking  except
that any amount awarded as compensation for the improvements to the Demised
Premises,  including  the Facility (but excluding  the  value  of  Tenant's
interest  in  the unexpired term of this lease), shall be paid  to  Tenant.

whichever  is earlier.  Landlord and Tenant shall thereupon be released  of
and  from  all obligations and liabilities to each other accruing hereunder
thereafter.  Tenant shall pay all Base Rent and Additional Rent accrued  up
to  the  time  of the Termination Date, and if any rent has  been  paid  in
advance Landlord shall return the surplus.

          contained shall continue in full force and effect for the balance

          awarded for compensation for the part of the Demised Premises  so
          taken  shall  be  paid to Landlord.  Tenant  hereby  grants  unto
          Landlord   the  entire  amount  of  the  award  or  compensation,
          expressly disclaiming all right, title and interest therein,  and
          agrees  that  it  shall have no claim for  any  damages  or  loss
          against Landlord by reason of such condemnation or taking, except
          that  any amount awarded as compensation for the improvements  to
          the  Demised Premises, including the Facility (but excluding  the
          value  of Tenant's interest in the unexpired term of this lease),
          shall  be paid to Tenant.  In the event of a partial taking  such
          that  Tenant's  reasonable use of the Demised Premises  shall  be
          materially  impaired, Tenant shall have the  right  to  terminate
          this lease as of the date title shall vest in

          the  portion  taken,  whichever is earlier,  by  giving  Landlord
          written notice.  Landlord shall give written notice to Tenant  of
          such  proposed  taking  specifying the  portion  of  the  Demised
          Premises  to be taken.  Tenant shall give its written  notice  of
          termination within 60 days after the giving of Landlord's notice.
          Tenant's notice shall state the date of termination (not prior to
          the date of Tenant's actual ouster from possession of the portion
          of  the  Demised Premises so taken) and upon that date  all  Base
          Rent   and  Additional  Rent  shall  be  apportioned  and   paid.
          Thereafter neither Landlord nor Tenant shall have any obligations
          to or rights against the other party hereunder.

23.3      If  the  temporary USO Of the whole or any part  of  the  Demised
          Premises shall be taken by any lawful power or authority  by  the
          exercise  of  the  right  of  condemnation,  eminent  domain   or
          otherwise, or by agreement between Tenant and those authorized to
          exercise  such right, Tenant shall give prompt notice thereof  to
          Landlord.   Landlord shall give prompt notice to  Tenant  of  any
          notice Landlord receives regarding on temporary taking of the use
          of  the whole or any part of the Demised Premises.  In that event
          the  Term shall not be reduced or affected in any way and  Tenant
          shall continue to pay in full the Base Rent, Additional Rent  and
          other  charges  herein reserved without reduction  or  abatement.
          Tenant  shall  be  entitled to receive for itself  any  award  or
          payment made for such use, provided, however, that if the  period
          of  temporary use shall extend beyond the Termination  Date,  the
          award  or  payment shall be ratably apportioned between  Landlord
          and Tenant.

23.4      The  terms  "condemnation", "taking" or similar terms  as  herein
          used  shall  mean the acquisition by a public or other  authority
          having  the  right  to take the same by condemnation  or  eminent
          domain  or  otherwise, regardless of whether such taking  is  the
          result  of  actual  condemnation or of  voluntary  conveyance  by
          Landlord.

23.5      Tenant  agrees to execute and deliver any instruments as  may  be
          deemed   necessary  by  Landlord  to  expedite  any  condemnation
          proceeding  or to effectuate a proper transfer of title  to  such
          governmental  or other authority seeking to take or  acquire  the
          Demised  Premises or any portion thereof.  Each party  agrees  to
          give  the other and Tenant's first leasehold mortgagee,  if  any,
          notice of any condemnation or similar proceeding.

23.6           Tenant shall have the right to participate in and appear at
          any condemnation proceeding involving the

          the  Facility (but excluding any claim with respect  to  Tenant's
          interest  in  the  unexpired term of this lease).   If,  however,
          Tenant shall assert a claim or right to claim, except for a claim
          permitted   by  the  provisions  of  the  immediately   preceding
          sentence,  Tenant  shall be liable to Landlord  for  all  damages
          sustained  and  all  expenses  incurred  by  Landlord,  including
          counsel fees and costs of legal proceedings, as a result  of  the
          assertion by Tenant of that claim.

     24.  SURRENDER BY TENANT AT END OF TERM

24.1      Subject to and except as otherwise provided by the provisions  of
          section 17 of this lease, Tenant will surrender possession of the
          Demised  Premises  and remove all goods and  chattels,  including
          equipment  and  moveable  trade  fixtures,  and  other   personal
          property in the possession of Tenant at the end of the Term or at
          such  other time as Landlord may be entitled to re-enter and take
          possession  of the Demised Premises pursuant to any provision  of
          this  lease.   Tenant shall leave the Demised  Premises  in  good
          order and condition.  Upon surrender of possession of the Demised
          Promises,    all    improvements,    additions,    installations,
          renovations, changes or alterations to the Demised Promises shall
          become  the  property of Landlord , subject to the  lien  of  the
          mortgage in favor of the. leasehold mortgagee, if then in effect,
          as  contemplated  by the Credit Agreement, which  mortgage  shall
          remain a lien on the Facility and any such improvements until all
          obligations  of Tenant to such leasehold mortgages are  satisfied
          in full or discharged.  In default of surrender of possession and
          removal of goods and chattels at the time aforesaid, Tenant  will
          pay  to  Landlord (a) the Basic Rent and Additional Rent reserved
          by the terms of this lease for such period as Tenant either holds
          over  in  possession of the Demised Premises or allows its  goods
          and  chattels or other personal property to remain in the Demised
          Premises and (b) statutory penalties and all other damages  which
          Landlord  shall  suffer  by  reason of  Tenant  holding  over  in
          violation  of  the terms and provisions of this lease,  including
          all  reasonable claims for damages made by any succeeding  tenant
          or  purchaser of the Demised Premises against Landlord which  may
          be  founded  upon delay by Landlord in giving possession  of  the
          Demised Premises to such succeeding tenant or purchaser,  so  far
          as  such  damages are occasioned by the unlawful holding over  of
          Tenant.

24.2      Subject to and except as otherwise provided by the provisions  of
          section 17 of this lease, if Tenant

                                    21



          fails  to  remove  all  goods  and chattels  and  other  personal
          property in possession of Tenant, by whomsoever owned, at the end
          of  the Term or at such other time as Landlord may be entitled to
          re-enter and take possession of the Demised Premises pursuant  to
          any  provision  of  this lease, Tenant hereby irrevocably  makes,
          constitutes  and appoints Landlord as the agent and  attorney-in-
          fact  of  Tenant  to  remove all goods  and  chattels  and  other
          personal property from the Demised Premises to a reasonably  safe
          place  of storage, the moving and storage to be at the sale  cost
          and  expense of Tenant.  Tenant covenants and agrees to reimburse
          and  pay  to Landlord all expenses which Landlord incurs for  the
          removal  and  storage  of all such goods and  chattels.   Without
          limiting  the foregoing, Tenant shall be deemed to have abandoned
          such goods, chattels and other personal property and Landlord may
          elect that the same shall become its property.

24.3      No act or thing done by Landlord shall be deemed an acceptance of
          the  surrender  of  the  Demised Premises unless  Landlord  shall
          execute  a  written release of Tenant and unless Tenant  and  any
          first  leasehold  mortgagee of Tenant  shall  also  execute  such
          written  release.   Tenant's liability  hereunder  shall  not  be
          terminated  by the execution by Landlord of a new  lease  of  the
          Demised Premises.
