            under the First  Mortgage and the  rescission  and  annulment of the
            consequences  thereof under the First  Mortgage  shall  constitute a
            waiver  of  the  corresponding  Event  of  Default  hereunder  and a
            rescission and annulment of the consequences thereof hereunder;

                                        8





      then,  unless the principal of all of the Notes shall have already  become
      due and  payable,  either  the  Trustee or the  Holders  of a majority  in
      aggregate  principal  amount of the Notes then  Outstanding,  by notice in
      writing to the Company (and to the Trustee if given by such Holders),  may
      declare  the  principal  of and  interest  on all the  Notes to be due and
      payable  immediately  and upon any such  declaration the same shall become
      immediately  due and payable,  anything in this  Indenture or in the Notes
      contained  to the  contrary  notwithstanding  and,  during the Senior Note
      First  Mortgage Bond Period,  upon the Notes being  declared to be due and
      payable,  the Trustee shall  immediately  file with the Mortgage Trustee a
      written  demand for  redemption of all Senior Note First Mortgage Bonds to
      the extent provided in the applicable provisions of the First Mortgage.

            The foregoing  paragraph,  however, is subject to the condition that
      if,  at any time  after the  principal  of the  Notes  shall  have been so
      declared  due and  payable,  and  before  any  judgment  or decree for the
      payment  of the  moneys  due  shall  have  been  obtained  or  entered  as
      hereinafter  provided,  and  during the Senior  Note First  Mortgage  Bond
      Period,  prior to the  acceleration  of all of the  first  mortgage  bonds
      issued and outstanding under the First Mortgage,  the Company shall pay or
      shall  deposit  with  the  Trustee  a sum  sufficient  to pay all  matured
      installments  of interest  upon all of the Notes and the  principal of and
      any premium on any and all Notes  which  shall have  become due  otherwise
      than by acceleration  (with interest on overdue  installments of interest,
      to  the  extent  that  payment  of  such  interest  is  enforceable  under
      applicable  law, and on such principal and any  applicable  premium at the
      rate borne by the Notes to the date of such  payment or  deposit)  and all
      sums  paid  or  advanced  by  the  Trustee   hereunder,   the   reasonable
      compensation,  expenses,  disbursements  and advances of the Trustee,  its
      agents and counsel,  and any other  amounts due the Trustee  under Section
      8.06 hereof, and any and all defaults under this Indenture, other than the
      non-payment of principal of and accrued interest on Notes which shall have
      become due solely by  acceleration  of Maturity,  shall have been cured or
      waived  (including any defaults under the First Mortgage,  as evidenced by
      notice  thereof from the  Mortgage  Trustee to the Trustee) -- then and in
      every such case such payment or deposit shall cause an automatic waiver of
      the Event of  Default  and its  consequences  (including,  if  given,  the
      written demand for redemption of all Senior Note First Mortgage Bonds) and
      shall cause an automatic  rescission and annulment of the  acceleration of
      the Notes;  but no such waiver or rescission and annulment shall extend to
      or shall  affect  any  subsequent  default,  or  shall  impair  any  right
      consequent thereon.

            (d)  Article  VII of the  Original  Indenture  as hereby  amended by
adding a new Section 7.12 thereto as follows:

            Section 7.12 Defaults Under The First Mortgage. In addition to every
                         ---------------------------------
      other  right and remedy  provided  herein,  during  the Senior  Note First
      Mortgage  Bond  Period,  the  Trustee  may  exercise  any  right or remedy
      available  to the  Trustee in its  capacity  as owner and holder of Senior
      Note First Mortgage Bonds which arises as a result of a completed  default
      under the First  Mortgage  whether or not an Event of  Default  under this
      Indenture shall then have occurred and be continuing.

                            SENIOR NOTE, BANK SERIES

                             DUE FEBRUARY 1, 2002

PENNSYLVANIA ELECTRIC COMPANY, a corporation of the Commonwealth of Pennsylvania

the benefit of the Lenders  referred to in such Credit  Agreement) or registered

on February 1, 2002,  in coin or currency of the United  States of America which
at the time of  payment  shall be legal  tender  for the  payment  of public and

upon  presentation  hereof,  and on each  Interest  Payment  Date (as defined in
Supplemental  Indenture  No. 1  hereinafter  referred  to),  and at Maturity (as
defined  in  Supplemental  Indenture  No. 1  hereinafter  referred  to),  to pay
interest thereon in like coin or currency at the rate specified below,  from the

respect to such principal sum shall be discharged.

                                       A-1





            The notes of this series shall bear  interest at the rate of ten per
centum (10%) per annum.  Interest on the notes of this series  during the period
of which  payment  is made  shall be  computed  in  accordance  with the  Credit
Agreement.

            This note is one of an issue of notes of the Company,  issued and to
be issued in one or more series under and equally and ratably secured (except as
any sinking,  amortization,  improvement,  renewal or other fund, established in
accordance  with the  provisions of the  indenture  hereinafter  mentioned,  may
afford  additional  security  for the  notes of any  particular  series)  by the
Indenture,  dated as of April 1, 1999 (the  "Original  Indenture"),  between the
Company and United States Trust Company of New York, trustee (the "Trustee"), as
supplemented  by  Supplemental  Indenture  No.  1,  dated as of May 1, 2001 (the
Original Indenture,  as so supplemented,  and such Supplemental  Indenture being
hereafter   called  the   "Indenture"  and   "Supplemental   Indenture  No.  1",
respectively),  to which Indenture reference is hereby made for a description of
the rights and limitations of rights of the Company, the Trustee and the holders
of said notes with  respect  to any  security  provided  by the  Indenture,  the
powers,  duties and  immunities of the Trustee,  the terms and  conditions  upon
which such notes are and are to be secured,  and the  circumstances  under which
additional  notes may be issued.  The acceptance of this note shall be deemed to
constitute  the consent and  agreement by the holder  hereof to all of the terms
and  provisions  of  the  Indenture.  This  note  is one of a  series  of  notes
designated as the Senior Notes, Bank Series, of the Company.

            The Company has issued and delivered the notes of this series to The
Chase Manhattan Bank, as Administrative Agent (the  "Administrative  Agent") and
for the benefit of the Lenders under the Amended and Restated Credit  Agreement,
dated as of May 1, 2001,  among the Company,  GPU, Inc.,  Jersey Central Power &
Light Company, Metropolitan Edison Company, the lenders parties thereto, and the
Administrative  Agent, as amended,  supplemented or otherwise modified from time
to time (the "Credit  Agreement")  in order to provide  further  evidence of the
obligation  of the  Company  thereunder  to pay  the  Advances  (as  defined  in
Supplement  Indenture  No. 1) and  interest  thereon as  specified in the Credit
Agreement.

            Upon  the  occurrence  of an  Event  of  Default  under  the  Credit
Agreement,  and  further  upon such  additional  conditions  as are set forth in
Section  2.01(g) of  Supplemental  Indenture No. 1 then all notes of this series
shall be redeemed  immediately  at the  principal  amount  thereof  plus accrued
interest to the date of redemption.

            The  obligation  of the Company to pay interest on the notes of this
Series on any  Interest  Payment  Date prior to Maturity  (a) shall be deemed to
have been  satisfied  and  discharged in full in the event that all amounts then
due in respect of interest  payable on the Advances shall have been paid and (b)
shall be deemed to remain unsatisfied in an amount equal to the aggregate amount
then due in respect of interest  payable on the  Advances and  remaining  unpaid
(not in excess, however, of the amount otherwise then due in respect of interest
on the notes of this Series).

                                       A-2





            The  obligation  of the Company to pay the  principal of and accrued
interest on the notes of this series at or after Maturity (x) shall be deemed to
have been  satisfied  and  discharged in full in the event that all amounts then
due in  respect of the  Advances  shall have been paid or (y) shall be deemed to
remain  unsatisfied  in an  amount  equal to the  aggregate  amount  then due in
respect of the Advances and remaining  unpaid interest (not in excess,  however,
of the amount otherwise then due in respect of principal of and accrued interest
on the notes of the series).

            The  principal  of this note and the  interest  accrued  hereon  may
become or be declared due and payable before the stated maturity hereof,  on the
conditions,  in the manner and at the times set forth in the Indenture, upon the
happening of a default as therein provided.

            This note is non-transferable  except as required to effect transfer
to any  successor  administrative  agent  under the Credit  Agreement,  any such
transfer  to be made at the  office or agency of the  Company in The City of New
York, upon surrender and cancellation of this note, and upon any such transfer a
new note of this series, for the same aggregate  principal amount and having the
same stated maturity date, will be issued to the transferee in exchange herefor.
Prior to due  presentment  for  registration  of  transfer,  the Company and the
Trustee may deem and treat the person in whose name this note is  registered  as
the absolute owner hereof for the purpose of receiving payment and for all other
purposes.  This note,  alone or with  other  notes of this  series,  may in like
manner be  exchanged  at such  office or  agency  for one or more  notes of this
series  of the same  aggregate  principal  amount  and  having  the same  stated
maturity date and interest rate, all as provided in the Indenture.

            No  recourse  shall be had for the  payment of the  principal  of or
interest on this note,  or for any claim based  hereon or  otherwise  in respect
hereof or of the Indenture, against any incorporator,  shareholder,  director or
officer,  as such, past, present or future, of the Company or of any predecessor
or  successor  corporation,  either  directly  or  through  the  Company  or any
predecessor  or successor  corporation,  whether by virtue of any  constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or by
any legal or equitable  proceeding or otherwise  howsoever  (including,  without
limiting the generality of the foregoing,  any proceeding to enforce any claimed
liability of shareholders of the Company,  based upon any theory of disregarding
the  corporate  entity of the  Company or upon any theory  that the  Company was
acting as the agent or instrumentality of the shareholders);  all such liability
being,  by the  acceptance  hereof  and as a part of the  consideration  for the
issuance hereof, expressly waived and released by every holder hereof, and being
likewise waived and released by the terms of the Indenture under which this note
is issued, as more fully provided in said Indenture.

            The Company,  at its option, and subject to the terms and conditions
provided in the Indenture,  will be discharged  from any and all  obligations in
respect of the notes (except for certain  obligations  including  obligations to
register  the  transfer  or  exchange  of the  notes,  replace  stolen,  lost or
mutilated notes,  maintain paying agencies and hold monies for payment in trust,
all as set forth in the  Indenture)  if the  Company  deposits  with the Trustee
cash, U.S. Government  Obligations which through the payment of interest thereon
and  principal  thereof in  accordance  with their terms will provide cash, or a
combination of cash and U.S. Government  Obligations,  in any event in an amount
sufficient,  without  reinvestment,  to pay all the principal of and any premium
and interest on the notes on the dates such payments are due in accordance  with
the terms of the notes.

                                       A-3





             If an Event of Default shall occur and be continuing, the principal
of the notes may be  declared  due and payable in the manner and with the effect
provided in the Indenture.

            The Indenture permits,  with certain exceptions as therein provided,
the amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the note  holders  under the  Indenture at any time by
the Company  and the Trustee  with the consent of the holders of not less than a
majority in  principal  amount of the  outstanding  notes.  Any such  consent or
waiver by the  holder of this note shall be  conclusive  and  binding  upon such
holder and upon all future  holders of this note and of any note issued upon the
registration  of  transfer  hereof or in exchange  therefor  or in lieu  thereof
whether or not notation of such consent or waiver is made upon the note.

            As set forth in and subject to the provisions of the  Indenture,  no
holder of any notes will have any right to institute any proceeding with respect
to the  Indenture  or for any remedy  thereunder  unless such holder  shall have
previously  given to the Trustee written notice of a continuing Event of Default
with respect to such notes, the holders of not less than a majority in principal
amount of the  outstanding  notes  affected by such Event of Default  shall have
made  written  request  and  offered  reasonable  indemnity  to the  Trustee  to
institute  such  proceeding  as Trustee  and the  Trustee  shall have  failed to
institute  such  proceeding  within  60  days;  provided,   however,  that  such
limitations  do not apply to a suit  instituted  by the  holder  hereof  for the
enforcement  of payment of the principal of and premium or interest on this note
on or after the respective due dates expressed here.

            No reference  herein to the Indenture and to provisions of this note
or of the Indenture  shall alter or impair the obligation of the Company,  which
is  absolute  and  unconditional,  to pay the  principal  of and any premium and
interest  on this note at the times,  places and rates and the coins or currency
prescribed in the Indenture.

            As provided  in the  Indenture  and  subject to certain  limitations
therein set forth,  this note may be transferred only as permitted by the legend
hereto.

            All terms used in this note which are defined in the Indenture shall
have the meaning assigned to them.

            This note shall not be valid or become  obligatory  for any  purpose
until the certificate of authentication  hereon shall have been signed by United
States  Trust  Company  of New York,  or its  successor,  as  Trustee  under the
Indenture.

                                       A-4
