      THIS LESSEE'S  LETTER  AGREEMENT  (the "Letter  Agreement")  is made as of
November 5, 1998, by and between  Metropolitan  Edison  Company,  a Pennsylvania
corporation  (the  "Lessee"),  TMI-1 Fuel  Corp,  a  Delaware  corporation  (the
"Company"), and The First National Bank of Chicago, as Administrative Agent (the
"Administrative Agent"), for the Banks party to the Credit Agreement referred to
below (the "Banks").

      WHEREAS,  the Lessee has  entered  into the Second  Amended  and  Restated
Nuclear Material Lease  Agreement,  dated as of November 5, 1998 ("Fuel Lease"),
with the  Company in order to enable the  Company  to obtain  financing  for the
acquisition,  processing and use of Nuclear Material in the Generating Facility;
and

      WHEREAS,  pursuant  to the Fuel  Lease,  the  Company  has  agreed to make
payments  due to  Manufacturers  and/or to  reimburse  the Lessee  for  payments
previously made to Manufacturers with respect to Nuclear Material; and

      WHEREAS,  in  order to  finance  the cost of such  Nuclear  Material,  the
Company  proposes  to (i)  sell  its  Commercial  Paper,  and  (ii)  obtain  the
Commitment of each Bank to make Loans from time to time as hereinafter provided;
and

      WHEREAS,  the  Lessee  has  agreed to make  payments  under the Fuel Lease
sufficient  to enable the Company to meet its  obligations  under the  Company's
financing  arrangements,  including the Company's  obligations  under the Credit
Agreement,  dated as of November 5, 1998,  among the Company,  the Banks and the
Administrative Agent (the "Credit Agreement");

      NOW,  THEREFORE,  in consideration  of the premises and mutual  agreements
herein  contained and other good and valuable  consideration,  so long as any of
the Loans or the Commercial Paper shall remain  outstanding,  or the Commitments
shall be  continuing,  notwithstanding  any  provision  of the Fuel Lease or any
other  agreement of the Lessee to the  contrary,  the Lessee,  the Company,  the
Administrative Agent and the Banks agree that:

      1. Definitions.  Unless the context otherwise specifies or requires,  each
term  defined in the Credit  Agreement  or Appendix A to the Fuel Lease,  shall,
when used in this Letter  Agreement,  have the meaning  indicated  in the Credit
Agreement or Appendix A or set forth in the paragraph indicated therein.

      2.    Performance of Fuel Lease and Liens.  The Lessee will perform and
comply with all the terms of the Fuel Lease to be performed or complied with
by it and will not omit to take an action the  omission of which  would cause a 






                                                                               2

Lease  Event of  Default.  The Lessee  acknowledges  that,  except as  otherwise
provided in the Fuel Lease,  its  obligations  as set forth under the Fuel Lease
are  absolute  and  unconditional.  The Lessee will not  directly or  indirectly
create or permit to be created or remain,  and will promptly take such action as
may be necessary  to  discharge,  any Lien on any  Collateral  except  Permitted
Liens.

      3.  Security  Interest  of  Collateral.  The  Lessee  represents  that  no
effective  financing statement (other than those naming the Secured Parties as a
secured  party)  covering all or any part of the  Collateral  (as defined in the
Security  Agreement relating to the Lessee) is on file in any public office. The
Lessee shall make, or shall cause to be made,  all filings and  recordings,  and
shall  take,  or cause to be taken,  such other  actions,  including  filing all
continuation  statements,  necessary  to  establish,  preserve  and  perfect the
Secured  Parties' lien on and security  interest in, the  Collateral as a legal,
valid and  enforceable  first priority lien and security  interest,  or purchase
money  security  interest,  as the case  may be,  therein,  subject  only to the
existence or priority of any Permitted Lien, and the Lessee  represents that all
such filings, recordings and other actions have been duly made. The Lessee shall
deliver  to  the  Administrative  Agent  evidence  of  the  due  filings  of any
continuation  statements to be delivered to the Administrative  Agent within the
time period specified in Section 7.05 of the Credit Agreement.  In no event will
the Lessee permit the Nuclear  Material to enter any  jurisdiction  in which all
necessary  action has not been taken to  establish,  maintain  and  protect  the
Secured  Parties'  first priority  perfected  lien and security  interest in the
Nuclear Material under the Security Agreement, subject only to Permitted Liens.

      4.  Sale of  Nuclear  Material  and  Assignment  of Rights  under  Nuclear
Material Contracts.

            (a) In the event that the Lessee  desires the Company,  on behalf of
the Lessee,  to purchase Nuclear Material or to have services  performed on such
Nuclear  Material  pursuant to any Nuclear Material  Contract,  the Lessee shall
provide the Company with an Assignment  Agreement and a Manufacturer's  Consent,
both substantially in the form of Exhibit D to the Fuel Lease, with such changes
to  Exhibit  2 to  Exhibit  D as the  Administrative  Agent  in  its  reasonable
discretion  may consent to in writing,  which consent shall not be  unreasonably
withheld,  with respect to such Nuclear  Material  Contract not later than sixty






                                                                               3

days  following  the date on which  the  Company  is to  purchase  such  Nuclear
Material or to have such services  performed  pursuant thereto.  Notwithstanding
the   foregoing,   the  Lessee  shall  not  be  required  to  have   obtained  a
Manufacturer's  Consent in any instance  where the  Manufacturer's  obligations
under the applicable  Nuclear  Material  Contract have been fully discharged and
performed,  and the  Manufacturer's  warranties  with  respect  to such  Nuclear
Material Contract have expired,  and the Lessee has delivered to the Company and
the Collateral Agent a certificate to such effect.

            (b) The Lessee at its expense  will  perform and comply with all the
terms and provisions of each Assigned Agreement to be performed or complied with
by it, will  maintain  each  Assigned  Agreement in full force and effect,  will
enforce each of the Assigned  Agreements  in  accordance  with their  respective
terms,  and  will  take  all such  action  to that end as from  time to time may
reasonably be requested by the Majority Banks.

            (c) The  Lessee  shall not enter  into or  consent  to or permit any
cancellation,  termination,  amendment,  supplement or modification of or waiver
with respect to any Assigned  Agreement without the prior written consent of the
Majority Banks, unless such cancellation,  termination, amendment, supplement or
modification  could not reasonably be expected to have a Material Adverse Effect
on the Company or the Company has through one or more other Assigned  Agreements
or otherwise  arranged for the  provision  of  comparable  goods and services on
terms not materially more burdensome to the Company.

            (d)  The  Lessee  will  from  time  to  time,  upon  request  of the
Administrative  Agent,  furnish to the  Administrative  Agent  such  information
concerning the Nuclear Material or any Assigned Agreement, as the Majority Banks
may reasonably request.

            (e) The Lessee  will not change its  principal  place of business or
chief executive offices from the location  specified in paragraph 8(a) hereof or
remove therefrom its records concerning the Assigned  Agreements unless it gives
the Administrative Agent at least 30 days' prior written notice thereof.

      5.  Collateral  Equivalence  Test; No Additional  Collateral or Covenants;
Condemnation Statements; Exercise of Rights of Secured Parties.








                                                                               4

            (a) The  Lessee  shall not permit  the sum of  aggregate  Stipulated
Casualty  Value of the  Nuclear  Material  leased  under the Fuel  Lease and the
Lessee's  Percentage of Cash Collateral to be less than the Lessee's  Percentage
of Outstandings.

            (b) The  Lessee  shall not  provide to any  Person  (other  than the
Banks),  in order to induce such  Person to extend  credit to the  Company,  any
collateral or any guarantee or other assurance against loss or non-payment,  nor
shall the Lessee consent to the provision thereof by the Company.

            (c) The  Lessee  shall  not  agree to any  affirmative  or  negative
covenant with respect to the  condition,  financial or otherwise,  of the Lessee
with any Person in order to induce such Person to extend credit to the Company.

            (d) The Lessee shall not sell, assign,  convey,  pledge or otherwise
dispose of or  encumber  in any manner any  interest it may have in the Trust or
any rights it may have under the Trust  Agreement.  The Lessee  shall not direct
the Owner  Trustee to  liquidate,  dissolve,  merge or  consolidate  the Company
except if such  transaction is consented to in writing by the Banks.  The Lessee
shall not direct the Owner Trustee to take any action under the Trust  Agreement
which is  inconsistent  with the duties  imposed  upon the  Company by the Basic
Documents and any other agreements, documents, instruments and articles executed
and  delivered,  and to be  executed  and  delivered,  by the Owner  Trustee  in
connection therewith.

            (e)  The  Nuclear   Material  leased  under  the  Fuel  Lease  shall
constitute  the Lessee's  entire  ownership  interest in the items used or to be
used by it as nuclear fuel in the  Generating  Facility.  The Lessee agrees that
50% of the Lessor's  ownership interest in any Nuclear Material which is subject
to the Fuel Lease will be leased to the Lessee. The Lessee further agrees not to
take any action  under the terms of the Fuel Lease,  including,  but not limited
to, the delivery of any Leasing  Record,  which would result in less than 50% of
the Lessor's ownership interest in any such Nuclear Material being so leased.

            (f) As provided in the Security Agreement,  (i) the Collateral Agent
on behalf of the Secured  Parties may, on and after the  occurrence  of a Credit
Agreement Default,  Credit Agreement Event of Default,  Lessee Default or Lessee
Event of Default, pursuant to Section 10 of the Security Agreement, exercise any
and all of the Company's  rights under the Fuel Lease,  the Assigned  Agreements
and each other Basic Document to






                                                                               5

which the Lessee is a party,  and (ii) if a Lease Event of Default occurs and is
continuing,  the Collateral Agent on behalf of the Secured Parties may, pursuant
to Section 10 of the Security Agreement, enforce and exercise any and all of the
Company's  rights under the Fuel Lease,  the Assigned  Agreements and each other
Basic  Document  to which the  Lessee is a party,  or the  rights  and  remedies
granted to the Secured Parties under the Security  Agreement at its election and
in its sole discretion, and, in the event that the Collateral Agent is permitted
to exercise such rights  pursuant to Section 10 of the Security  Agreement,  the
Lessee agrees that the  Collateral  Agent may do so either in concert with or in
place of the Company, and the Lessee shall assist in, comply with and perform in
accordance  with  all  rights  or  remedies  so  enforced  or  exercised  by the
Collateral Agent for the ratable benefit of the Secured Parties.

      6. Fuel Management;  Quiet Enjoyment. The occurrence of a Credit Agreement
Default,  a Credit  Agreement Event of Default,  Lease Event of Default,  Lessee
Default,  Lessee Event of Default or an event or condition which would, with the
lapse of time or the giving of notice or both,  become a Lease Event of Default,
shall not affect the  Lessee's  sole  obligation  to engage in Fuel  Management;
provided  that,  upon the  occurrence  of a Credit  Agreement  Event of Default,
Lessee Event of Default or Lease Event of Default,  the Collateral Agent may, if
so directed by the Majority  Secured  Parties,  by written notice to the Lessee,
elect to revoke such power and authority,  in which case the Person from time to
time designated by the Majority  Secured Parties may (but shall not be obligated
to), to the extent that the Majority  Secured  Parties  desire and to the extent
permitted by law, engage in Fuel Management and/or remove all or any part of the
responsibility  for Fuel Management from the Lessee;  provided,  however,  that,
subject to the right of the Collateral Agent and the Majority Secured Parties to
exercise  any or all rights  granted to the Secured  Parties  under the Security
Agreement,  the rights granted to the Collateral  Agent and the Majority Secured
Parties  under this  Section 6 shall not be  construed  to include  the right to
direct,  whether  directly  or  indirectly,  the  operation  of  the  Generating
Facility.  In the event the Majority  Secured  Parties,  in accordance  with the
preceding  sentence,  shall revoke the Lessee's power and authority to engage in
Fuel  Management,  all rights conferred by the Company to the Lessee pursuant to
Section 3 of the Fuel Lease shall be deemed to be  automatically  reassigned  to
the Company and the Lessee shall execute such  documents and  instruments as the
Collateral Agent shall request to further confirm such assignment.







                                                                               6

      7. Insurance.  Each year, the Lessee will furnish the Administrative Agent
and each Bank a detailed  statement  certified  by an officer of Lessee  setting
forth (i) the location of all Nuclear  Material and (ii) the insurance  policies
and  indemnification  agreements  provided pursuant to Sections 14 and 17 of the
Fuel Lease and  certifying  that such  insurance  policies  and  indemnification
agreements  comply with the  requirements  of the Fuel Lease.  In addition,  the
Lessee shall promptly  furnish at any time to the  Administrative  Agent and any
Bank such  information  as any such Bank  shall  reasonably  request  concerning
location of Nuclear Material,  insurance policies and indemnification agreements
and  Manufacturers  or other third  parties  with whom  arrangements  exist with
respect to transportation, storage or processing of Nuclear Material.

      8.  Representations  and  Warranties.  The Lessee  hereby  represents  and
warrants to the Company,  the Administrative  Agent and the Banks that as of the
date hereof:

            (a)  Organization  and Standing.  The Lessee is a  corporation  duly
incorporated, validly existing and subsisting under the laws of the Commonwealth
of  Pennsylvania,  and is  qualified  to do  business  in each  state  or  other
jurisdiction  in which  the  nature of its  business  makes  such  qualification
necessary, except where the failure to be so qualified would not have a material
adverse  effect on its  ability to perform  its  obligations  under this  Letter
Agreement  or each other  Basic  Document  to which the  Lessee is a party.  The
Lessee's chief  executive  office is located at 2800 Pottsville  Pike,  Reading,
Pennsylvania 19605.

            (b)  Corporate  Authority.  The Lessee has the  corporate  power and
authority to execute and perform this Letter Agreement and the Fuel Lease and to
lease the Nuclear Material thereunder. The execution and delivery of this Letter
Agreement  and the Fuel Lease and the lease of the Nuclear  Material  thereunder
will not have a material adverse effect on the financial  condition,  results of
operations, business, properties or operations of the Lessee.

            (c) Compliance with Other Instruments,  etc. The execution, delivery
and  performance by the Lessee of this Letter  Agreement and each Basic Document
to which the Lessee is a party,  and other  related  instruments,  documents and
agreements,  and the compliance by the Lessee with the terms hereof and thereof,
(i) have been duly and legally authorized by appropriate  corporate action taken
by the Lessee, (ii) are not in






                                                                               7

contravention  of, and will not result in a  violation  or breach of, any of the
terms  of  the  Lessee's  articles  of  incorporation,  its  by-laws  or of  any
provisions  relating to shares of the capital stock of the Lessee and (iii) will
not violate or constitute a breach of any provision of (x) any  applicable  law,
order,  rule or  regulation,  rule or regulation of any  governmental  authority
(except in those cases where  non-compliance  with any such law, order,  rule or
regulation could not reasonably be expected to have a material adverse effect on
the  financial  condition,  results  of  operations,   business,  properties  or
operations of the Lessee or its ability to perform its obligations  hereunder or
under each Basic Document) or (y) any indenture,  agreement or other  instrument
to which  the  Lessee is party,  or by or under  which the  Lessee or any of the
Lessee's  property  is bound,  or be in conflict  with,  result in breach of, or
constitute  (with due  notice  and/or  lapse of time) a  default  under any such
indenture,  agreement or instrument,  or result in the creation or imposition of
any Lien upon any of the Lessee's property or assets or any Nuclear Material.

            (d) Legal Obligations. This Letter Agreement and the Fuel Lease have
been  executed  by a duly  authorized  officer of the  Lessee,  and this  Letter
Agreement and the Fuel Lease constitute,  and each Leasing Record, when executed
by a duly  authorized  officer of the Lessee and delivered to the Company,  will
constitute,  the legal, valid and binding obligations of the Lessee, enforceable
against the Lessee in  accordance  with their  respective  terms,  except as the
enforceability  thereof  may be limited by the Atomic  Energy Act and the rules,
regulations or orders issued pursuant thereto,  or by bankruptcy,  insolvency or
other similar laws affecting the  enforcement  of creditors'  rights in general,
and except as the availability of the remedy of specific  performance is subject
to general  principles of equity (regardless of whether such remedy is sought in
a proceeding in equity or at law).

            (e)  Governmental  Consents.  Neither the  execution and delivery of
this Letter Agreement,  the Fuel Lease or any Leasing Record by the Lessee,  nor
the performance by the Lessee of all of its obligations hereunder or thereunder,
requires  the  consent  or  approval  of,  the  giving  of  notice  to,  or  the
registration,  filing or  recording  with,  or the taking of any other action in
respect of, any Federal,  state,  local or foreign  government  or  governmental
authority or agency or any other person  except for the order of the  Securities
and Exchange  Commission (the "SEC"),  dated October 25, 1995, the filing of the
supplemental  order of the SEC dated  November 3, 1998,  the order of the PaPUC,
dated






                                                                               8

September 17, 1998, and the filing of any statement or other instrument pursuant
to Section 10(b) of the Fuel Lease, and except for the filing of certificates by
the Lessee with the SEC pursuant to SEC Rule 24 under the Public Utility Holding
Company  Act to report on the  transactions  authorized  by such SEC order,  the
filing of which is not  necessary  to the  execution  or delivery of this Letter
Agreement,  the Fuel  Lease  or any  Leasing  Record  by the  Lessee  or for the
performance by the Lessee of any of its obligations hereunder or thereunder, and
the failure to file any of which will not affect the validity or  enforceability
of any of this Letter Agreement, the Fuel Lease or any Leasing Record.

            (f)  Consents  and  Permits.   The  Lessee  possesses  all  material
licenses,   permits,   franchises  and  certificates   which  are  necessary  or
appropriate to own or operate its material  properties and assets and to conduct
its business as now conducted.

            (g)  Litigation.  There is no  litigation  or other  proceeding  now
pending  or,  to the best of the  Lessee's  knowledge,  threatened,  against  or
affecting  the  Lessee,  before  any  court,  arbitrator  or  administrative  or
governmental  agency (i) which would adversely affect or impair the title of the
Company  to  the  Nuclear  Material,   (ii)  which  questions  the  validity  or
enforceability of this Letter Agreement, the Fuel Lease, the Assigned Agreements
or any other Basic  Document to which the Lessee is a party or any action  taken
or to be taken by the  Lessee  pursuant  to or in  connection  with this  Letter
Agreement,  or (iii) except as disclosed in the Lessee's  Annual  Report on Form
10-K for the year ended December 31, 1997 and Quarterly  Report on Form 10-Q for
the quarter ended June 30, 1998,  copies of which have previously been delivered
to the  Administrative  Agent and the Banks,  which, if decided adversely to the
Lessee, would materially adversely affect the condition, financial or otherwise,
of the Lessee.

            (h)  Taxes.  The  Lessee  has  filed or  caused  to be filed all tax
returns  which are  required to be filed,  and has paid or caused to be paid all
taxes as shown on said returns and all assessments  received by it to the extent
that  such  taxes  and  assessments  have  become  due,  except  for  taxes  and
assessments  which  are  being  contested  in  good  faith  and  by  appropriate
proceedings  and as to which it has  provided  reserves  which are  adequate  in
connection with generally accepted accounting principles.








                                                                               9

            (i) Reaffirmation and Restatement of Representations and Warranties.
The Lessee  repeats and  reaffirms  as of the date hereof for the benefit of the
Administrative  Agent and each Bank the  representations  and warranties made by
the Lessee in the Fuel Lease as though  set forth in full  herein  with the same
effect as though such  representations and warranties had been made on and as of
the date hereof. In addition,  the Lessee represents and warrants that as of the
date hereof (i) the Lessee is in  compliance  with all the terms and  provisions
set forth in the Fuel Lease on its part to be  observed  or  performed,  (ii) no
Terminating  Event has occurred and no event has occurred which,  with the lapse
of time or the giving of notice,  or both,  would  constitute such a Terminating
Event, and (iii) no Lease Event of Default has occurred and is continuing and no
event has occurred and is continuing on such date which,  with the lapse of time
or the giving of notice, or both, would constitute a Lease Event of Default.

            (j) First Perfected Security  Interest.  Except for Permitted Liens,
upon the  execution  and  delivery of this  Letter  Agreement  and the  Security
Agreement and the due filing of the Uniform Commercial Code financing statements
required to be executed  and filed from time to time,  the Secured  Parties will
have a legal,  valid and enforceable first priority security interest (i) in the
rights, titles and interests of the Company in and to the Fuel Lease and (ii) in
and to the other Collateral.  Such security interest will constitute a perfected
security interest in the Collateral consisting of Nuclear Material Contracts and
the Collateral consisting of Nuclear Material located in the States of Illinois,
Kentucky, Ohio, Pennsylvania and Virginia,  except for any such Collateral which
consists of cash,  instruments  (as defined in the New York  Uniform  Commercial
Code) and other  items in which a security  interest  may only be  perfected  by
possession,  enforceable  against all third  parties as security for the Secured
Obligations.

            (k) No Material Adverse Change.  Since June 30, 1998, there has been
no material  adverse change in the financial  condition,  results of operations,
business,  properties  or  operations of the Lessee or in its ability to perform
its obligations under the Basic Documents.

            (l) No  Defaults.  The  Lessee  is not in  default  under  any bond,
debenture,  note or any other  evidence of  Obligations  for  Borrowed  Money or
Deferred  Purchase  Price  or any  mortgage,  deed  of  trust,  indenture,  loan
agreement or other agreement  relating  thereto,  where the amount thereof is in
excess of $20,000,000.





                                                                              10

            (m) Pension Plans. No accumulated  funding deficiency (as defined in
Section 302 of ERISA and Section 412 of the Code), whether or not waived, exists
with respect to any plan (other than a multiemployer  plan). No liability to the
Pension Benefit  Guaranty  Corporation has been, or is expected by the Lessee to
be, incurred with respect to any plan (other than a  multiemployer  plan) by the
Lessee which is or would be materially adverse to the Lessee. The Lessee has not
incurred and presently does not expect to incur any withdrawal  liability  under
Title IV of ERISA with  respect to any  multiemployer  plan which is or would be
materially  adverse to the Lessee.  Neither the  execution  and  delivery by the
Company of the Credit Agreement and the other Basic Documents,  and the issuance
of the  Commercial  Paper,  nor the execution and delivery by the Lessee of this
Letter Agreement, the Trust Agreement and each other Basic Document to which the
Lessee  is a  party,  will  involve  any  transaction  which is  subject  to the
prohibitions  of Section 406 of ERISA or in connection with which a tax could be
imposed pursuant to Section 4975. As used herein,  the term "plan" shall mean an
"employee  pension benefit plan" (as defined in Section 3 of ERISA) which is and
has been established or maintained,  or to which  contributions are or have been
made,  by the Lessee or by any trade or business,  whether or not  incorporated,
which,  together with the Lessee is under common control as described in Section
414(b) or (c) of the Code, and the term "multiemployer plan" shall mean any plan
which is a "multiemployer  plan" (as such term is defined in Section  4001(a)(3)
of ERISA).

            (n) Financial Statements. The audited balance sheet of the Lessee as
of  December  31,  1997,  and the  related  statements  of income and cash flows
(including the notes  thereto) of the Lessee for the year then ended,  copies of
which have been  delivered  to the  Company,  the  Administrative  Agent and the
Banks, and all other annual or quarterly financial statements including, without
limitation,  the  quarterly  statement  dated as of June 30,  1998 so  delivered
fairly present the financial condition of the Lessee on the dates for which, and
the results of its  operations  for the  periods  for which,  the same have been
furnished  and  have  been  prepared  in  accordance  with  generally   accepted
accounting principles consistently applied.

            (o) Nuclear Material.  The Nuclear Material is free and clear of any
Lien in favor of any  Person  claiming  by,  through  or under the Lessee or any
Affiliate  thereof,  other than Permitted  Liens. No default or event which with
the giving of notice or lapse of time would  constitute  a default has  occurred
and is continuing under any Nuclear Material Contract.






                                                                              11

            (p)  Disclosure.   Neither  the   representations   in  this  Letter
Agreement,  or in any other  document,  certificate  or  statement  furnished in
writing to the Administrative Agent or any Bank by or on behalf of the Lessee in
connection  with  the  transactions  contemplated  hereby,  nor the  information
disclosed in the Lessee's Annual Report on Form 10-K for the year ended December
31, 1997 or Quarterly  Report on Form 10-Q for the quarter  ended June 30, 1998,
contained as of its date, any untrue  statement of a material fact or omitted to
state a  material  fact  necessary  in order  to make  such  representations  or
information not misleading in light of the  circumstances  under which they were
made.

            (q)  Collateral  Equivalence  Test  Met.  The  sum of the  aggregate
Stipulated  Casualty Value of the Nuclear  Material  leased under the Fuel Lease
and the  Lessee's  Percentage  of the Cash  Collateral  equals  or  exceeds  the
Lessee's Percentage of the Outstandings.

            (r) Year 2000. The Lessee has made a full and complete assessment of
its Year 2000 Issues and has a realistic and achievable Year 2000 Program. Based
on such assessment and on its Year 2000 Program,  the Lessee does not reasonably
anticipate that Year 2000 Issues will have a Material Adverse Effect.

      9. General Covenants of the Lessee.

            (a)  Information.  The Lessee  will  furnish to the  Company and the
Administrative Agent in sufficient copies for each Bank:

            setting forth in each case in  comparative  form the figures for the
            corresponding periods in the previous fiscal year, all in reasonable
            detail and certified as complete and






                                                                              12

            a principal  financial  officer of the Lessee;  provided  that it is
            understood  that the  delivery of the Lessee's  Quarterly  Report on
            Form 10-Q shall be deemed to satisfy the  requirements  with respect
            to such financial statements;

            year, setting forth in each case in comparative form the figures for
            the previous  fiscal year, all in reasonable  detail and accompanied
            by an opinion thereon of independent certified public accountants of
            recognized  national standing selected by the Lessee,  which opinion
            shall state that such  financial  statements  have been  prepared in
            accordance   with   generally   accepted    accounting    principles
            consistently  applied  (except for changes in  application  in which
            such   accountants   concur)  and  that  the   examination  of  such
            accountants in connection  with such  financial  statements has been
            made in  accordance  with  generally  accepted  auditing  standards;
            provided  that it is  understood  that the  delivery of the Lessee's
            Annual   Report  on  Form  10-K  shall  be  deemed  to  satisfy  the
            requirement with respect to such financial statements;

      caused  to be made,  under  such  officer's  supervision,  a review of the
      transactions  and financial  condition of the Lessee from the beginning of
      the accounting  period covered by the income  statements  being  delivered
      therewith to the date of the certificate, and that the Lessee has observed
      or performed  all of its  covenants  and other  agreements,  and satisfied
      every condition,  contained in this Letter  Agreement,  the Fuel Lease and
      any  other  Basic  Document  to  which  the  Lessee  is a  party,  and  no
      Terminating Event, Lessee Default, Lessee Event of Default, Lease Event

      has occurred and is continuing and no event has occurred and is continuing

      such  accountants  have reviewed the relevant  terms and conditions of the
      Fuel Lease and other Basic  Agreements to which the Lessee is a party, and
      that,  in  making  the  examination   necessary  for  the  audit  of  such
      statements,  they have  obtained no  knowledge  of any  condition or event
      which  constitutes  or which  with  notice or lapse of time or both  would
      constitute a Terminating Event,  Lessee Default,  Lessee Event of Default,
      Lease Event of Default or default or event of default under any such Basic
      Document, or if such accountants shall have obtained knowledge of any such
      condition or event,  specifying in such certificate each such condition or

      Year 2000 Issues),  which could  reasonably be expected to have a Material
      Adverse Effect, and (B) within 10 days of becoming aware of the occurrence

      financial  statements  which the Lessee may file  annually  with any state

      reasonably requested by the Administrative Agent or any Bank.

            (b) Notice of Litigation. Immediately upon the Lessee becoming aware
thereof,  written  notice of (i) any  litigation or  proceedings  which would be
required to be disclosed as an exception to the  representations  and warranties
contained  herein or in the Fuel  Lease in order that such  representations  and
warranties would be true and correct on a continuing basis; and (ii) any dispute
between the Lessee and any governmental authority or other party relating to any
part of the  transactions  contemplated  by this Letter  Agreement or any of the
other Basic Documents to which the Lessee is a party which would have a material
adverse  effect  on the  ability  of the  Lessee  to carry  out its  obligations
hereunder  or under any other  Basic  Document  to which the  Lessee is a party;
provided,  however,  that the notice  requirement  in this Section 9(b) shall be
satisfied if the Lessee  furnishes the Company and the  Administrative  Agent in
sufficient








                                                                              15

copies for each Bank a Current Report on Form 8-K regarding the event  requiring
notice by the time that the  Current  Report is  required  to be filed  with the
Securities and Exchange Commission.

            (c)  General  Obligations.  Subject  to the  last  sentence  of this
Section 9(c), the Lessee will:

            (i)   duly comply with all laws, rules, orders, regulations or
                  other valid requirements (including, without limitation,
                  any of the foregoing which are applicable to Nuclear
                  Material or the operation of the Generating Facility) of
                  any governmental authority necessary to the conduct of its
                  business or to its properties or assets, noncompliance with
                  which could reasonably be expected to have a material
                  adverse effect upon the transactions contemplated by this
                  Letter Agreement or any other Basic Document, or upon the
                  financial condition, results of operations, business,
                  properties or operations of the Lessee, or the ability of
                  the Lessee to carry out its obligations under any Basic
                  Document or this Letter Agreement);

            (ii)  continue  to  engage   principally  in  the  electric  utility
                  business;

            (iii) obtain,  maintain  and  keep  in full  force  and  effect  all
                  consents,  permits,  licenses  and  approvals,  the absence of
                  which   would  have  a  material   adverse   effect  upon  the
                  transactions  contemplated  by this  Letter  Agreement  or any
                  other Basic  Document to which the Lessee is a party,  or upon
                  the  financial  condition,  results of  operations,  business,
                  properties or operations of the Lessee,  or the ability of the
                  Lessee  to  carry  out  its  obligations   under  this  Letter
                  Agreement or any other Basic Document to which the Lessee is a
                  party;

            (iv)  maintain its material  operating  properties used or useful in
                  its  business  in good  repair,  working  order and  condition
                  consistent with prudent utility practice;  provided,  however,
                  that the Lessee shall not be prevented from  discontinuing the
                  operation and maintenance of any of its properties if it shall
                  determine that the







                                                                              16

                  continued operation and maintenance of such properties is
                  no longer necessary, desirable or permissible;

            (v)   pay when due all fees,  taxes,  assessments  and  governmental
                  charges  or  levies  imposed  upon it or upon  its  income  or
                  profits or upon any  property  belonging  to it, and  maintain
                  appropriate reserves for the accrual of the same in accordance
                  with generally accepted accounting principles;

            (vi)  except  as  permitted  by  clause  (vii)  below,  at all times
                  maintain its corporate existence,  privileges,  franchises and
                  rights to carry on business, and duly procure all renewals and
                  extensions thereof, if and when any shall be necessary;

            (vii) not consolidate or merge with, or sell or otherwise dispose of
                  all or  substantially  all of its properties and assets to any
                  Person  unless (i) the  surviving or  resulting  entity is the
                  Lessee hereunder, (ii) immediately after giving effect thereto
                  no  Credit  Agreement  Event  of  Default,   Credit  Agreement
                  Default, Lease Event of Default,  Lessee Default, Lessee Event
                  of Default or event which with the giving of notice or passage
                  of time would  constitute a Lease Event of Default  shall have
                  occurred  and be  continuing,  and (iii) the senior  unsecured
                  debt of the  surviving or  resulting  Lessee shall be rated at
                  least  investment  grade by  Standard & Poor's  Ratings  Group
                  ("S&P") or Moody's Investor Service, Inc. ("Moody's");

           (viii) perform and comply  with each of the  material  provisions  of
                  each material indenture,  credit agreement,  contract or other
                  agreement  by which the  Lessee is bound,  non-performance  or
                  non-compliance with which would have a material adverse effect
                  upon its  business  or credit or in any way affect its ability
                  to perform its obligations hereunder except material contracts
                  or other agreements being contested in good faith;

            (ix)  preserve  and  maintain   its   corporate   existence  in  the
                  jurisdiction of its incorporation, and qualify






                                                                              17

                  and remain qualified as a foreign corporation in good standing
                  in each jurisdiction in which such  qualification is necessary
                  or desirable in view of its  business  and  operations  or the
                  ownership of its properties, except where the failure to be so
                  qualified would not materially  adversely affect its financial
                  condition,  operations,  properties or business,  and preserve
                  its material rights,  franchises and privileges to conduct its
                  business substantially as conducted on the date hereof;

            (x)   maintain insurance in effect at all times in such amounts
                  as are available to the Lessee and covering such risks as
                  is usually carried by companies of a similar size, engaged
                  in similar businesses and owning similar properties
                  (including, without limitation, the operation and ownership
                  of nuclear generating facilities) in the same general
                  geographical area in which the Lessee operates, either with
                  responsible and reputable insurance companies or
                  associations, or, in whole or in part, by establishing
                  reserves of one or more insurance funds, either alone or
                  with other corporations or associations;

            (xi)  at any  reasonable  time and from  time to  time,  permit  the
                  Administrative   Agent   or  any   Bank  or  any   agents   or
                  representatives  thereof  to  examine  and make  copies of and
                  abstracts  from the records and books of account of, and visit

                  whether or not related,  except for dispositions of its fossil

                                                                              18

                  Documents  to which the Lessee is a party in  accordance  with
                  the  respective  terms and  conditions  set forth  herein  and
                  therein; and

            (xiv) except for Permitted  Liens,  permit the creation of any Liens
                  on the Collateral.

Notwithstanding  the foregoing  provisions of this Section 9(c),  the Lessee may
contest by  appropriate  proceedings  conducted in good faith and due diligence,
the  amount,  validity  or  application,  in whole  or in part of any fee,  tax,
assessment or government charge or levy, or any legal requirement, provided that
the Lessee shall have set aside on its books adequate  reserves,  if required in
accordance with generally  accepted  accounting  principles with respect thereto
and shall furnish such security, if any, as may be required in the proceeding.

      10. GPU Events.  It shall be a default hereunder if GPU, Inc. (a) fails to
maintain at all times  beneficial  ownership of at least 75% of all  outstanding
shares of common stock of each of the Lessee, JCP&L and Penelec; or (b) pledges,
grants options on,  creates any charge on or security  interest in, or otherwise
subjects to any charge or  encumbrance,  any of the common  stock of the Lessee,
JCP&L or Penelec unless the  obligations  hereunder are secured ratably and with
equal priority,  in form and substance  reasonably  satisfactory to the Majority
Banks.

      11. Credit Agreement and Notes. The Lessee hereby acknowledges  receipt of
executed  counterparts  of the Credit  Agreement and  photostatic  copies of the
Notes  evidencing the Loans,  and consents to all of the terms and provisions of
the Credit Agreement and the Notes.

      12.  Consent to  Assignment;  Direct  Payment of  Payments  Under the Fuel
Lease.

            (a) Consent to Assignment.  The Lessee hereby acknowledges notice of
and  consents to all the terms and  provisions  of the  Security  Agreement  and
hereby confirms to and agrees with the Secured Parties that all representations,
warranties,  indemnities  and agreements of the Lessee  contained in this Letter
Agreement  and each other  Basic  Document  to which the Lessee is a party shall
inure to the benefit of, and shall be






                                                                              19

enforceable  by,  the  Secured  Parties  to the same  extent as if such  Secured
Parties were  originally  parties to or named in such documents and  agreements.
The Lessee further acknowledges and consents to the assignment and transfer, and
any future  assignments and transfers,  to the Secured Parties by the Company of
the Company's right to exercise any and all of its rights, remedies,  powers and
privileges (but none of its obligations,  duties or liabilities)  under the Fuel
Lease, the Assigned Agreements and each other Basic Document to which the Lessee
is a party. The Lessee hereby agrees with the Secured Parties to comply with any
exercise by the Secured Parties,  either directly or through the Company, of any
rights,  remedies,  powers or privileges pursuant to the Security Agreement. The
Secured Parties acknowledge that neither the Security Agreement nor this Section
12  shall  in any  way  add to the  obligations  of  the  Lessee  (except  those
obligations  of the Lessee to any Person,  which,  if not  previously so, hereby
become  enforceable  directly by the Secured  Parties) under the Fuel Lease, the
Assigned  Agreements  and each  other  Basic  Document  to which the Lessee is a
party. Notwithstanding the foregoing, so long as no Lease Event of Default shall
have  occurred  and be  continuing,  the Lessee  shall have  exclusive  right to
possession and use of the Nuclear Material in accordance with the Fuel Lease and
may use such Nuclear  Material for any lawful purpose  consistent  with the Fuel
Lease.

            (b) Direct  Payment of  Payments  Under the Fuel  Lease.  The Lessee
acknowledges  that it has been  directed  by the  Company to, and agrees that it
will, make all payments of monies due and to become due to the Company under the
Fuel Lease,  the Assigned  Agreements and each other Basic Document to which the
Lessee  is a  party,  directly  to  the  Collateral  Agent,  including,  without
limitation,  Basic Rent, Additional Rent, the purchase price of Nuclear Material
pursuant  to  Section  8(c),  8(d),  8(e) and 8(g) of the Fuel  Lease,  payments
pursuant to Sections  9(e), 14, 17 and 18 of the Fuel Lease in the manner and to
the  accounts of the Secured  Parties as specified in Section 3.03 of the Credit
Agreement.

      13.  Severability.  Any  provision  of  this  Letter  Agreement  which  is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition or  unenforceability,  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.







                                                                              20

To the  extent  permitted  by  applicable  law,  the  Lessee  hereby  waives any
provision of law which renders any provision hereof  prohibited or unenforceable
in any respect.

      14. Indemnification.  The Lessee shall pay and indemnify and hold harmless
the  Administrative   Agent  and  each  Bank,  and  their  respective  officers,
directors, incorporators, shareholders, partners, employees, agents and servants
from and against any and all liabilities (other than liabilities  arising out of
the gross negligence or willful misconduct of such Person),  taxes,  (excluding,
however,  taxes measured  solely by the net income of any Person  indemnified or
intended to be  indemnified  pursuant to this  Section 14,  except as  otherwise
provided in Section 14 hereof), losses, obligations, claims, damages, penalties,
causes of action,  suits,  costs and expenses  (including,  without  limitation,
reasonable  attorneys' and accountants'  fees and expenses) and judgments of any
nature  arising  from or in any  way  relating  to any and all of the  following
during the term of the Fuel Lease and thereafter:  (a) any injury to or disease,
sickness  or death of  Persons,  or loss of or  damage  to  property,  occurring
through or resulting  from any nuclear  incident (as that term is defined in the
Atomic Energy Act, 42 U.S.C. section 2011 et seq.) involving or connected in any
way with the  Nuclear  Material  or any portion  thereof,  (b) the  acquisition,
ownership  (including  strict liability of an owner or liability without fault),
possession,  disposition,  sale,  use,  nonuse,  misuse,  leasing,  fabrication,
design,   cycling,   recycling,   transportation,   containerization,   cooling,
processing,    reprocessing,    storing,   condition,   management,   operation,

portion  thereof or resulting  from the  condition of adjoining  and  underlying
land,  buildings,  streets or ways, (c) any use,  nonuse or condition of, or any
other matter of  circumstance  relating to, the Generating  Facility,  any other
property associated  therewith or any adjoining and underlying land,  buildings,
streets and ways, (d) any violation or default, or alleged violation or default,
of the Fuel Lease or this Letter Agreement by or on behalf of Lessee,  or of any
contracts or  agreements to which the Lessee is a party or by which it is bound,

furnishing of any materials or other property in respect of the Nuclear Material
or any portion  thereof,  (f) any  infringement  or alleged  infringement of any
patent,  copyright,  trade secret or other similar right relating to the Nuclear
Material  or  any  portion  thereof,  (g)  Lessee's  agreements  or  obligations
contained in the Fuel Lease or this Letter Agreement,







                                                                              21

(h) any claim  arising out of loss of damage to the  environment,  (i) any claim
arising out of strict or absolute  liability  in tort,  or (j) the  offering and
sale of  Commercial  Paper.  The Lessee also  indemnifies  each  indemnitee,  as
aforesaid, from and against all other liabilities,  taxes, losses,  obligations,
claims,  damages,  penalties,  causes  of  action,  suits,  costs  and  expenses
(including, without limitation,  reasonable attorneys' and accountants' fees and
expenses) and  judgments of any nature which may be imposed on,  incurred by, or
asserted at any time  against any  indemnitee  in any way relating to or arising
out of the  performance  of this Letter  Agreement,  the Fuel Lease or any other
Basic  Document  to which  Lessee is a party,  provided,  except for claims of a
nature  contemplated  by (i) above,  that the Lessee  shall not be  required  to
indemnify any  indemnitee  with respect to any liability  relating to or arising
out of  indemnitee's  gross  negligence  or  willful  misconduct  and  provided,
further,  that the foregoing immunity shall not limit the terms of any indemnity
that the Lessee may grant separately to any indemnitee  pursuant to any separate
agreement.  In the event that any action,  suit or proceeding is brought against
the  Company or any other  Person  indemnified  or  intended  to be  indemnified
pursuant to this Section 14 by reason of any such occurrence,  the Lessee shall,
at the Lessee's  expense,  resist and defend such action,  suit or proceeding or
cause the same to be resisted and defended by counsel  designated  by the Lessee
and reasonably acceptable to the Person or Persons indemnified or intended to be
indemnified under this Section 14 provided there is no conflict of interest with
the Person or Persons  indemnified  or  intended  to be  indemnified  under this
Section 14. In the event a conflict of interest  contemplated  by the proviso of
the immediately preceding sentence shall exist, then the Person or Persons as to
which such conflict  exists may be defended by counsel of its or their choice at
Lessee's expense, provided Lessee's obligation for such expense shall be limited
to one  firm for all  such  Persons  as to which  such a  conflict  exists.  The
obligations of the Lessee under this Section 14 shall survive any termination of
this Letter  Agreement,  the Credit  Agreement,  the Fuel Lease or the  Security
Agreement, in whole or in part.

      15.  No  Waiver;   Amendments.   Neither  the  Administrative  Agent,  the
Collateral  Agent,  the Banks,  the  Company nor the Lessee  shall,  by any act,
delay,  omission  or  otherwise,  be deemed to have waived any of its rights and
remedies hereunder, and no waiver shall be valid unless in writing signed by the
party or  parties  sought to be bound  thereby.  A waiver by the  Administrative
Agent,  the  Collateral  Agent,  the Banks,  the Company or the Lessee of any of
their respective rights or






                                                                              22

remedies  hereunder on any one  occasion  shall not be construed as a bar to any
right or remedy which the  Administrative  Agent,  the Banks, the Company or the
Lessee,  as  applicable,  would  otherwise have had on any future  occasion.  No
failure  to  exercise  nor any  delay in  exercise  of any such  right or remedy
hereunder shall preclude any other or future exercise or partial exercise of any
other right or remedy. The rights and remedies hereunder provided are cumulative
and may be exercised singly or concurrently, and are not exclusive of any rights
and remedies  provided by law.  None of the terms or  provisions  of this Letter
Agreement may be waived, altered, modified or amended except by an instrument in
writing, duly executed by the party or parties sought to be bound thereby.

      16.  Successors  and  Assigns.   This  Letter  Agreement  shall  bind  the
successors  and  assigns of the Lessee and the  Company  and shall  inure to the
benefit of  permitted  successors  and assigns of either.  The Letter  Agreement
shall not be assignable by the Lessee or the Company,  either  voluntarily or by
operation  of law,  unless  consented  to by the  Administrative  Agent  and the
Majority  Banks.  No  permitted  assignment  by the Lessee or the Company  shall
release the Lessee or the Company from any of its  obligations  hereunder.  This
Letter  Agreement  shall inure to and shall be binding upon the  successors  and
assigns of the Administrative Agent and the Banks.

against it as provided for in Section 11.08 of the Credit Agreement.

            (b) Lessee agrees that it shall have no right of set-off,  deduction
or  counterclaim  in  respect  of  its  obligations  hereunder,   and  that  the
obligations  of the Banks  hereunder and under the Credit  Agreement are several

waiver of the Lessee's rights to any independent  claim that the Lessee may have
against the Administrative  Agent or any Bank for the Administrative  Agent's or
such Bank's, as the case may be, gross negligence or willful misconduct,  but no

involving (a) the accuracy or  completeness  of any  representation  or warranty
made under the Basic  Documents by Lessee,  (b) the performance by Lessee of any

construed and interpreted in accordance with the laws of the State of New York.
