         THIS LESSEE'S LETTER  AGREEMENT (the "Letter  Agreement") is made as of
November 5, 1998, by and between  Pennsylvania  Electric 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






                                                                               2

it and will not omit to take an action the omission of which would cause a 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,








                                                                               3

which consent shall not be unreasonably  withheld,  with respect to such Nuclear
Material  Contract  not later than sixty  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
25% 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 25% 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 contravention of, and






                                                                               7

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

                  year,  and (B)  statements  of  income  and cash  flows of the
                  Lessee  for  such  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

                  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;

                 (iii) Officer's Compliance Certificate. Simultaneously with the
         financial  statements  referred  to in  Sections  9(a)(i)  and (ii),  a

         Lessee  has  observed  or  performed  all of its  covenants  and  other

         Agreement,  the Fuel Lease and any other  Basic  Document  to which the
         Lessee is a party, and no Terminating

         or  default  or event of  default  under any such  Basic  Document  has
         occurred and is continuing  and no event has occurred and is continuing

         Default,  Lease Event of Default or a default or event of default under
         any such Basic Document or, if such condition or event has occurred and

         party,  and that, in making the examination  necessary for the audit of
         such  statements,  they have  obtained no knowledge of any condition or

         Default,  Lease  Event of Default or default or event of default  under
         any such Basic  Document,  or if such  accountants  shall have obtained

         other   development,   financial  or  otherwise   (including,   without
         limitation, developments with respect to 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  thereof,  notice of
         any other material event affecting the






                                                                              14

         Lessee's  obligations  under any Basic Document or any Nuclear Material

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

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;








                                                                              17

                    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

                    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

                    transactions,   whether   or   not   related,   except   for
                    dispositions  of its  fossil  and  hydroelectric  generating
                    stations and associated  facilities and  dispositions of its
                    current  assets  in  the  ordinary  course  of  business  as
                    presently  conducted,  if  immediately  prior to such  sale,

                    Basic 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,  Met-Ed and JCP&L; 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,
Met-Ed or JCP&L 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







                                                                              19

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  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






                                                                              20

render  unenforceable  such provision in any other  jurisdiction.  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,
construction,  maintenance,  repair or rebuilding of the Nuclear Material or any
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,
or any Legal  Requirements,  (e)  performance  of any labor or  services  or the
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







                                                                              22

Company or the Lessee of any of their respective rights or 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.

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
Bank shall be liable for the  conduct of the  Administrative  Agent or any Bank,
and the Administrative Agent shall not be liable for the conduct of any Bank.

         19. Waiver of Jury Trial.  Lessee irrevocably waives all right to trial

foregoing  shall not  preclude any party  hereto from  submitting  to a jury for
determination  in any  such  action,  proceeding  or  counterclaim  any  dispute
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
affirmative or negative covenant or agreement  contained in the Basic Documents,

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