ITEM 1.  DESCRIPTION OF PROPOSED TRANSACTIONS.
         ------------------------------------

     A.  By Order dated October 29, 2001 (HCAR No.  27459) (the "Merger Order"),
as supplemented by a Supplemental Order dated November 5, 2001 (HCAR No. 27463),
the Commission  authorized the  acquisition of GPU, Inc.  ("GPU") by FirstEnergy
Corp.  ("FirstEnergy")  pursuant to an Agreement  and Plan of Merger dated as of
August 8, 2000 (such acquisition,  the "Merger"). The Merger was effective as of
November 7, 2001 and, after the Merger,  all of the direct  subsidiaries of GPU,
including GPU Diversified Holdings LLC ("GPUDH"),  became direct subsidiaries of
FirstEnergy. By Orders dated December 17, 1996 (HCAR No. 26631) and December 26,
1996  (HCAR No.  26635)  (collectively,  the  "Prior  Orders"),  the  Commission
authorized GPU International,  Inc. ("GPUI"),  a then-wholly owned subsidiary of
GPU, to invest up to $30 million in Ballard  Generation  Systems Inc. ("BGS"), a
Canadian  corporation  which at that time was to become a joint venture  between
GPUI and Ballard Power Systems Inc. ("BPS"), a Canadian  corporation.1  The sole
purpose of BGS was, and is, to develop,  manufacture and market stationary power
systems  employing fuel cell technology  ("Stationary Fuel Cell Power Systems").
On December 24, 1996,  GPUI  purchased  300,001 Class B Voting Common shares and

____________________

1  The Prior Orders also  authorized  GPUI to acquire  warrants  ("Warrants") to
purchase 100,000 BPS common shares.  As a result of subsequent BPS stock splits,
the Warrants represented the right to purchase 300,000 BPS common shares.



290,300  Class C Non-Voting  Preferred  shares in the capital of BGS for a total
purchase price of  $5,903,000,  and over the course of the next two years and in
accordance with the Prior Orders purchased 1.3 million additional BGS shares for
a  total  additional  purchase  price  of  $13  million.2   As a  result of  the
restructuring  described  in  paragraph  B  below,  GPUDH,  a  Delaware  limited
liability company that, as a result of the Merger, is now a direct, wholly-owned
subsidiary of  FirstEnergy,  currently  owns 1,425,001  Class B  Voting  Common3
shares and  890,300  Class C  Non-Voting  Preferred  shares.  The  shares  GPUDH
currently owns represent,  in the aggregate,  approximately  12.6% of the equity
and 8.7% of the outstanding  voting securities of BGS.  Additionally,  since May
1998, two other  investors have  purchased  substantial  amounts of BGS stock so
that  currently  there are four BGS  shareholders.

     B.  In December 2000, the GPU system effected an internal restructuring, in
connection  with which GPUI was sold to a third party and all of the  GPUI-owned
Class B and Class C BGS shares and an option to purchase an  additional  425,000

____________________

2  Such 1.3  million  additional  BGS shares  consist of 250,000  Class B shares
purchased on October 24, 1997, 150,000 Class B shares and 100,000 Class C shares
purchased  on November  24,  1997,  300,000  Class B shares and 100,000  Class C
shares  purchased on June 12, 1998 and 400,000 Class C shares purchased on March
29, 2000.
3  This 1,425,001 amount includes  425,000 Class B shares acquired by GPUDH upon
the June 2001 exercise of its option to purchase such shares,  which it acquired
from GPUI as discussed in Paragraph B of this Item 1. 2

                                       2




Class B BGS shares,4 which has since been exercised,  were  transferred to GPUDH
and the Warrants were transferred to GPU. GPU exercised the warrants in December
2000,  and,  at the time of the  Merger,  held less  than 1% of the  outstanding
voting securities of BPS.  FirstEnergy now holds those BPS shares as a result of
the Merger.

     C.  BPS and GPUDH now desire to restructure the GPUDH-BGS investment, which
would include the  acquisition  by BPS of all of GPUDH's Class B and Class C BGS
shares  in  exchange for  restricted  BPS  shares.5   Accordingly,  GPUDH  seeks
authority  to acquire an amount of BPS shares  having a value equal to the value
of the BGS shares to be exchanged,  as agreed  between BPS and GPUDH.  For these
purposes,  the BGS shares to be exchanged will be valued at U.S. $19.50 a share,
which was the  purchase  price paid by the last BGS  investor  to  purchase  BGS
shares.  The BGS shares will then be  exchanged  for BPS shares  having an equal
value,  as determined by the current  "Market Value" of BPS's common shares,  as
defined.6  At no time will GPUDH own, directly or indirectly, 10% or more of the

____________________

4  The transfer of the shares and option to GPUDH was effected  first  through a
distribution  of such shares and option  from GPUI to GPU  followed by a capital
contribution of those shares and option from GPU to GPUDH.
5  FirstEnergy  currently anticipates  that the other BGS  shareholders may also
exchange  their  BGS  shares  for BPS  shares  and that  BGS will be  dissolved,
although there can be no assurance as to the outcome of discussions between such
other BGS shareholders and BGS/BPS.
6  The "Market  Value"  for each BPS share is the  average of the sale price per
share of BPS's common shares as reported on the NASDAQ  National  Market for the
10 trading days ending three business days before the share  exchange  documents
were executed.  BPS shares are traded on the Toronto Stock Exchange  ("TSE") and
the NASDAQ National Market ("NASDAQ"). Based on this formula, GPUDH will receive
1,366,063 BPS shares.

                                       3





outstanding BPS voting common shares. In fact,  GPUDH's ownership is expected to
represent less than 2% of the outstanding BPS shares.

     D.  The  principal  business  of BPS and its  associated  companies  is the
development,  manufacture and  commercialization  of proton  exchange  membranes
("PEM")  fuel  cells  and PEM  fuel  cell  systems  for  use in  transportation,
stationary,  portable  and other  power  operations.  A PEM fuel  cell  produces
electricity using a combination of hydrogen fuel and oxygen, without combustion.
It is an environmentally clean electrochemical  device that produces electricity
efficiently and continuously. BPS has developed PEM fuel cells and PEM fuel cell
systems for 17 years and such  development has been BPS's primary business since
1989.  FirstEnergy  believes  that BPS would  qualify as a Rule 58 company if it
conducted  its  business  solely  in  the  United  States,  instead  of  Canada.
Commercialization  of BPS  products  is  scheduled  to take  place over the next
several years. BPS recently launched a portable volume-produced fuel cell system
designed for integration by original equipment manufacturers into a wide variety

                                       4



of industrial and consumer  end-product  applications.  BPS intends to introduce
the first fuel cell stationary  power generators into the market by 2003. In the
transportation markets, fuel cell-powered transit bus engines are expected to be
available  in 2002,  and the first  fuel  cell-powered  automobile  engines  are
expected to be available  between 2003 and 2005.  All of BPS's sales  revenue is
derived from PEM fuel cell products.

     BPS has two  development  and  manufacturing  facilities,  one in  Burnaby,
British  Columbia  and one in  Nabern,  Germany,  and  offices  in  Burnaby  and
Sacramento,  California. BPS has 820 employees in Canada, 35 in Germany and four
in the United States.

     E.  In connection with gpudh's acquisition of the BPS shares, BPS will need
TSE approval to issue and deliver the BPS shares to GPUDH.  In  particular,  the
TSE must approve the deemed price at which the BPS shares are to be issued.  All
BPS shares  issued to GPUDH will have a holding  period with respect to sales in
the  United  States  of  up to 12  months,  in  accordance  with  United  States
securities  laws.  Sales in the United  States after one year will be limited by
the constraints of Rule 144 under the Securities Act of 1933, as amended.  Sales
in Canada  will be  restricted  for four  months  in  accordance  with  Canadian
provincial securities laws.

                                       5




     F.  GPUDH also has entered into a distribution agreement with BGS, pursuant
to which  GPUDH  will be a  non-exclusive  distributor  of BGS's  PEM fuel  cell
stationary  power  generators  in a  portion  of the  United  States  once  such
generators  become  commercially  available.

     G.  Rule 54  Analysis.

         The proposed  transaction is also  subject to the  requirements of Rule
54.  Rule 54 provides that in determining whether to approve an application by a
registered  holding  company  which  does not  relate  to any  exempt  wholesale
generator  ("EWG") or "foreign utility company"  ("FUCO"),  the Commission shall
not  consider  the effect of the  capitalization  or earnings of any  subsidiary
which is an EWG or a FUCO upon the registered holding company if paragraphs (a),
(b) and (c) of Rule 53 are satisfied.

         FirstEnergy currently meets all of the conditions of Rule 53(a), except
for clause  (1).  In the Merger  Order,  the  Commission,  among  other  things,
authorized  FirstEnergy  to  invest  in EWGs  and  FUCOs  so that  FirstEnergy's
"aggregate  investment," as defined in Rule 53(a)(1), in EWGs and FUCOs does not
exceed $5 billion,  which  amount is above the level which would be permitted by
clause (1) of Rule 53(a) if such amount  were to be  currently  calculated.  The

                                       6




Merger  Order also  specifies  that this $5 billion  amount may include  amounts
invested  in EWGs and  FUCOs by  FirstEnergy  and GPU at the time of the  Merger
Order ("Current Investments") and amounts relating to possible transfers to EWGs
of certain  generating  facilities owned by certain of  FirstEnergy's  operating
utilities  ("GenCo  Investments").  FirstEnergy  has  made the  commitment  that
through June 30, 2003, its aggregate investment in EWGs and FUCOs other than the
Current Investments and GenCo Investments ("Other  Investments") will not exceed
$1.5 billion.  The Commission has reserved  jurisdiction  over  investments that
exceed such amount.

         As of June 30,  2002,  and on the same basis as set forth in the Merger
Order,  FirstEnergy's  aggregate  investment in EWGs and FUCOs was approximately
$1.2 billion,7 an amount significantly below the $5 billion amount authorized in
the Merger Order.

         In any event,  even  taking  into  account  the  capitalization  of and
earnings  from EWGs and FUCOs in which  FirstEnergy  currently  has an interest,
there  would  be no  basis  for  the  Commission  to  withhold  approval  of the
transactions proposed herein. With respect to capitalization,  since the date of
the Merger Order,  there has been no material  adverse  impact on  FirstEnergy's
consolidated capitalization resulting from FirstEnergy's investments in EWGs and
FUCOs. Additionally, the proposed transactions will not have any material impact

____________________

7  This $1.2 billion amount represents Current Investments only. As of September
30, 2002, FirstEnergy had no Genco Investments.

                                       7





on FirstEnergy's  capitalization.  Further,  since the date of the Merger Order,
and,  after  taking into  account  the effects of the Merger,  there has been no
material change in FirstEnergy's level of earnings from EWGs and FUCOs.

         FirstEnergy satisfies all of the other conditions of paragraphs (a) and
(b) of Rule 53. With respect to Rule 53(a)(2),  FirstEnergy  maintains books and
records in conformity with, and otherwise adheres to, the requirements  thereof.
With respect to Rule 53(a)(3), no more than 2% of the employees of FirstEnergy's
domestic public utility companies render services,  at any one time, directly or
indirectly,  to EWGs or FUCOs in which FirstEnergy  directly or indirectly holds
an interest. With respect to Rule 53(a)(4), FirstEnergy will continue to provide
a copy of each  application  and  certificate  relating  to EWGs and  FUCOs  and
relevant  portions of its Form U5S to each  regulator  referred to therein,  and
will otherwise comply with the requirements thereof concerning the furnishing of
information. With respect to Rule 53(b), none of the circumstances enumerated in
subparagraphs (1), (2) and (3) thereunder have occurred.  Finally, Rule 53(c) by

                                       8




its terms is inapplicable  since the proposed  transaction  does not involve the
issue or sale of a security to finance the  acquisition of an EWG or FUCO.

ITEM 2. FEES, COMMISSIONS AND EXPENSES.
        -------------------------------

     The estimated  fees,  commissions  and expenses  expected to be incurred in
connection with the proposed transactions will be filed by amendment.

ITEM 3.  APPLICABLE STATUTORY PROVISIONS.
         -------------------------------

     FirstEnergy  believes  that  Sections  9(a)  and 10 of the Act and  Rule 54
thereunder may be applicable to the proposed transactions.  FirstEnergy believes
that the  authorization  sought herein is consistent  with the  requirements  of
Sections 10 and 11(b) of the Act which permit  public  utility  holding  company
subsidiaries  to engage in other  businesses "as are reasonably  incidental,  or
economically necessary or appropriate to the operations" of an integrated public
utility system.  Indeed,  the acquisition of BPS stock by the FirstEnergy System
would be exempt from the  requirements of Sections 9(a) and 10 of the Act if BPS
were a United  States-based  company (instead of  Canadian-based),  by virtue of
Rule 58 under the Act and,  in  particular,  Section  (b)(1)(ii)  thereof.  As a
consequence,  FirstEnergy believes that the acquisition of the BPS shares by the
FirstEnergy  System is  appropriate.  The Commission has in the past  authorized

                                       9





registered   holding   companies   to  invest  in   companies   that  engage  in
"energy-related"  activities of the kind  authorized  by Rule 58 in Canada.  See
Cinergy Corp., HCAR No. 27124 (Jan. 11, 2000).

ITEM 4.  REGULATORY APPROVALS.
         --------------------

     No state  commission  has  jurisdiction  with  respect to any aspect of the
transactions  and  no  Federal  commission,  other  than  your  Commission,  has
jurisdiction with respect to any aspect thereof.

ITEM 5.  PROCEDURE.
         ---------

     FirstEnergy requests that the Commission issue an order with respect to the
transactions  proposed herein at the earliest  practicable date, but in no event
no later than January 31, 2002. It is further requested that: (i) there not be a
recommended decision by an Administrative Law Judge or other responsible officer
of the Commission,  (ii) the Office of Public Utility Regulation be permitted to
assist in the  preparation  of the  Commission's  decision and (iii) there be no
waiting  period between the issuance of the  Commission's  order and the date on
which it is to become effective.
