Item 5. Other Events

   Amended Merger Agreement. On September 23, 1999, Unicom Corporation
("Unicom") and PECO Energy Company ("PECO"), issued a joint press release
announcing that they, along with a wholly owned subsidiary of PECO ("Exelon"),
had entered into an Agreement and Plan of Exchange and Merger, dated as of
September 22, 1999 (the "Merger Agreement"). On January 7, 2000, the Agreement
and Plan of Exchange and Merger was amended and restated (the "Amended Merger
Agreement") to: (a) accelerate approximately $1.5 billion of common stock
repurchases of which Unicom intends to repurchase approximately $1.0 billion
(in addition to the 26.3 million shares of Unicom common stock that Unicom
expects to repurchase no later than February 2000 under certain forward
purchase contracts), and PECO intends to repurchase approximately $500 million
(in addition to the 44.0 million shares of PECO common stock that was
purchased in 1999 with proceeds from its 1999 securitization of stranded
costs) and (b) amend the consideration Unicom common shareholders will receive
in the merger to consist of 0.875 shares of Exelon common stock plus $3.00 in
cash per share of Unicom common stock. The dual cash election available to
PECO and Unicom shareholders has been eliminated. The above description of the
Amended Merger Agreement does not purport to be complete and is qualified in
its entirety by reference to the provisions of the Amended Merger Agreement
which is being filed with the Securities and Exchange Commission as an exhibit
to this Current Report on Form 8-K.

   PECO is filing this Form 8-K to provide additional information about the
transactions contemplated by the Amended Merger Agreement before PECO
commences repurchases of shares of its common stock. Nothing contained herein
shall be considered a solicitation of any proxy to approve such transactions.

   PECO expects that it will commence share repurchases following the filing
hereof and will continue purchasing shares from time to time on the open
market or through negotiated purchases.

Item 7. Financial Statements and Exhibits

 (b) Pro Forma Financial Information

   Unaudited Pro Forma Combined Condensed Financial Statements. The following
unaudited pro forma combined condensed financial statements have been prepared
to reflect the acquisition of Unicom by PECO under the purchase method of
accounting. The historical consolidated financial statements of Unicom have
been adjusted to give effect to the sale of ComEd's fossil generating plants
and the annualized effects of Unicom's issuance of securitization notes and
related use of proceeds ("Unicom Pro Forma Adjustments"). ComEd completed the
sale of its fossil generating plants during the fourth quarter of 1999. The
historical consolidated financial statements of PECO have been adjusted to
give effect to its use of the remaining proceeds from its securitization of
stranded costs ("PECO Pro Forma Adjustments"). The unaudited pro forma
financial statements do not give effect to the estimated cost savings and
revenue enhancements as a result of the merger or the costs to achieve such
savings and revenue enhancements or one-time merger-related costs. The Unicom
and PECO Pro Forma Adjustments and the merger are reflected in the unaudited
combined condensed pro forma balance sheets as if they occurred on September
30, 1999. The unaudited pro forma combined condensed statements of income for
the nine months ended September 30, 1999 and for the year ended December 31,
1998 assume that these transactions were completed on January 1, 1998.

   The unaudited pro forma combined condensed financial statements do not
reflect potential adjustments to Unicom's assets and liabilities to reflect
fair value, as will be required upon consummation of the merger under purchase
accounting. Such adjustments to the book value of assets and liabilities could
be significant, particularly with respect to Unicom's nuclear generating
stations. The fair value of the nuclear generating stations is expected to be
determined considering, among other things, independent appraisals or expected
cash flows. To the extent the fair value of Unicom's nuclear generating
stations is ultimately determined to be less than the September 30, 1999 book
value of $6.9 billion, additional goodwill and/or an identifiable intangible
asset will be recorded.

                                       2

   The following unaudited pro forma financial statements should be read in
conjunction with the consolidated historical financial statements and related
notes of PECO and Unicom, which are included in their respective Annual Report
on Form 10-K for the year ended December 31, 1998 and Quarterly Reports on
Form 10-Q for the quarter ended September 30, 1999. PECO has provided all the
information included in this Form 8-K regarding PECO and its subsidiaries.
Unicom has provided all the information included in this Form 8-K regarding
Unicom and its subsidiaries. Neither PECO nor Unicom assumes any
responsibility for the accuracy or completeness of the information provided by
the other party.

   The following unaudited pro forma financial statements are for illustrative
purposes only. They are not necessarily indicative of the financial position
or operating results that would have occurred had these transactions been
completed on January 1, 1998 or September 30, 1999, as assumed above; nor is
the information necessarily indicative of future financial position or
operating results.

   Results of operations and financial position in the first year after
consummation could differ significantly from the unaudited pro forma combined
condensed financial statements, which are based on past operations.

   Future operations will be affected by various factors including operating
performance, energy market developments, and other matters.

   The historical financial statements of PECO included in the accompanying
pro forma combined condensed financial statements for the nine months ended
September 30, 1999 are unaudited. The December 31, 1998 historical financial
statements of PECO and Unicom and the September 30, 1999 historical financial
statements of Unicom were derived from audited financial statements but do not
include all disclosures required by GAAP.

   Forward-looking statements. Except for historical data, the information
contained in this Form 8-K constitutes forward-looking statements. Forward-
looking statements are inherently uncertain and subject to risks and the
statements should be viewed with caution. Actual results or experience could
differ materially from the forward-looking statements as a result of many
factors, including without limitation, those factors discussed below or
elsewhere in this Form 8-K.

   The forward-looking statements in this Form 8-K include the statements
regarding the estimated number of shares of Unicom common stock to be
purchased by Unicom under the terms of the Amended Merger Agreement; the
estimated number of shares of PECO common stock expected to be purchased under
the terms of the Amended Merger Agreement; the expected source of funds
necessary to provide the cash consideration in the merger and to acquire
Unicom and PECO common stock prior to the closing of the merger.

   These forward-looking statements are subject to numerous assumptions, risks
and uncertainties. Factors that may cause actual results to differ from those
indicated by such forward-looking statements include, among others, the
following:

  . The fact that these forward-looking statements are based on information
    of a preliminary nature which may be subject to further and continuing
    review and adjustment,

  . The risk of legislative, regulatory or other governmental action seeking
    to impose additional restrictions on the operations of Unicom or PECO or
    Exelon or to increase the burden of necessary regulatory approvals for
    the merger, or the imposition of unfavorable terms as a condition of
    approval of the merger,

  . The risk of a significant delay in the expected completion of, and
    unexpected consequences resulting from the merger, including the
    inability to close the transaction or unexpected difficulties in
    integrating the operations of the two companies,

  . Changes in the number of shares of outstanding common stock of Unicom and
    PECO for reasons not foreseen at the date hereof,

                                       3
<PAGE>

  . Changes in the amount of proceeds received by the companies from asset
    sales, securitization transactions or other factors affecting the amount
    and timing of receipt of available funds to provide the cash
    consideration for the merger or share repurchases,

  . Future state and federal regulatory and/or legislative initiatives,

  . The development of competition in the utility industry, including;
    legislative and regulatory restructuring initiatives, industry
    restructuring initiatives, transmission system operation, recovery of
    investments made under traditional regulation, nature of competitors
    entering the industry, retail wheeling, new pricing structures and former
    customers entering the generation market,

  . Economic conditions, including inflation rates, generally and in the
    markets served by PECO and Unicom,

  . Trade, monetary, fiscal, taxation and environmental policies of
    governments, agencies and similar organizations in geographic areas where
    PECO or Unicom has a financial interest,

  . Financial or regulatory accounting principles or policies imposed by the
    Financial Accounting Standards Board, the Securities and Exchange
    Commission, the Federal Energy Regulatory Commission, the Nuclear
    Regulatory Commission and similar agencies with regulatory oversight,

  . Factors affecting utility and nonutility operations such as unusual
    weather conditions, catastrophic weather-related damage, unscheduled
    generation outages, maintenance or repairs, unanticipated changes to
    fossil fuel, nuclear fuel or gas supply costs or availability due to
    higher demand, shortages, transportation problems or other developments,
    nuclear or environmental incidents, or electric transmission or gas
    pipeline system constraints, all of which may affect revenues and
    margins,

  . Employee workforce factors, including loss or retirement of key
    executives, collective bargaining agreements with union employees, union
    organizing activities or work stoppages,

  . Nuclear plant operating risks and nuclear regulatory policies and
    procedures, including nuclear decommissioning costs and related funding
    requirements, operating regulations and spent nuclear fuel storage,

  . Cost and other effects of legal and administrative proceedings,
    settlements, investigations and claims,

  . Technology developments resulting in competitive disadvantages and
    creating the potential for impairment of existing assets,

  . Factors associated with unregulated investments, including government
    actions, economic risks, partnership actions, competition, operating
    risks, dependence on certain suppliers and customers, and environmental
    and energy regulations, and

  . Changes in the number of shares of common stock of Unicom and PECO that
    will be repurchased prior to completion of the merger caused by changing
    market prices for those shares or other factors.

   Unicom and PECO make no commitment to disclose any revisions to the
forward-looking statements, or any facts, events or circumstances after the
date hereof that may bear upon the forward-looking statements.

   2. Reflects the accounting impacts related to the December 1999 sale of the
fossil generating plants. The sale is expected to result in an after-tax gain
of approximately $1.6 billion, after settling commitments associated with
certain coal contracts ($350 million), recognition of employee severance costs
($112 million) and funding certain environmental initiatives as required by
Illinois law upon the closing of the sale ($250 million).

   The employee related costs reflect employee severance costs associated with
selling the fossil generating plants. Such costs include certain pension and
post-retirement welfare benefits, transition allowances and retention payments
offered to employees whose positions were eliminated as of the date of the
asset sale in December 1999.

   The gain on the sale was utilized to recover certain regulatory assets and,
as a result, the sale is not expected to have a significant impact on Unicom
net income in 1999. Both the amortization of regulatory assets and the gain on
the fossil sale are reflected on the depreciation and amortization line of the
pro forma income statement.

   3. Reflects the continuing impact of the sale of ComEd's fossil generating
plants:

  . Fuel and Energy Interchange: Reflects the elimination of fossil fuel
    expense and the replacement impact of purchasing power under the power
    purchase agreements entered into with the purchaser of the fossil assets
    at the time of the fossil sale, as provided below:

    depreciation and amortization expense includes the following amounts (in
    millions):

</TABLE>

   Amortization of regulatory liabilities represents the application of the
   gain on the sale of the fossil plants to recover regulatory assets. The
   total pre-tax gain on the fossil sale used to recover regulatory assets
   is $2,756 million, which includes $43 million of Investment Tax Credit
   (ITC) amortization related to fossil plant. The amortization of ITC's is
   reflected in income taxes. The Unicom Fossil Sale Pro forma adjustments
   include increased regulatory asset amortization because those adjustments
   on a prior-to-merger, pro forma basis would result in ComEd's earnings
   exceeding the earnings cap provision of the Illinois Public Utilities
   Act.

   For the nine-month period ended September 30, 1999, depreciation and
   amortization expense includes the following (in millions):

<TABLE>
      <S>                                                                 <C>
      Continuing Impacts:
        Elimination of Fossil Plant Depreciation......................... $(57)
</TABLE>

  . Taxes Other Than Income Taxes: Reflects the elimination of real estate
    and payroll taxes related to the ownership of the fossil plants.

   The pro forma adjustments do not reflect the income effects of the
reinvestment of cash proceeds received from the fossil sale.

   4. Reflects Unicom's expected obligation to purchase, at prevailing market
prices, approximately 26.3 million shares of Unicom common stock that are
subject to certain forward purchase contracts and are expected to settle no
later than February 2000. Also reflects the use of securitization proceeds to
retire $140 million of long-term debt in October 1999. In addition, reflects
adjustments to net interest expense and preferred and preference stock
dividends related to the use of securitization proceeds. The Unicom
Securitization Pro Forma adjustments include increased regulatory asset
amortization because those adjustments on a prior-to-merger, pro forma basis
would result in ComEd's earnings exceeding the earnings cap provision of the
Illinois Public Utilities Act.

   5. Reflects the payment of the cash portion of the merger consideration to
Unicom common shareholders. PECO's pro forma cash balance as of September 30,
1999 was insufficient to fully fund this cash payment. Accordingly, for pro
forma purposes, it was assumed that PECO would borrow $200 million from its
available revolving credit facility and that this borrowing would be repaid
immediately following the merger. The amount of actual borrowing, if any, at
the time of consummation of the merger will depend on PECO's actual cash
available at that time.

   6. Reflects issuance of Exelon shares in exchange for PECO and Unicom
common stock net of shares which were repurchased by PECO and Unicom as
follows:

</TABLE>

   7. A pro forma adjustment has been made to recognize estimated goodwill in
connection with the merger. The goodwill represents the excess of the purchase
consideration of $5.7 billion, including PECO's estimated transaction costs
resulting from the merger, over the book value of Unicom's assets and
liabilities at September 30, 1999. The adjustment reflects the merger
consideration including approximately 144.6 million shares of Exelon Common
Stock at a price of $35.96 based on the average closing price of PECO Common
Stock between January 4 and 11, 2000, (the most current data available as of
the date of this 8-K filing). PECO's transaction costs of approximately $32.5
million represent the estimated costs to be incurred for the merger that meet
the requirements for inclusion in the purchase price. Actual goodwill recorded
upon consummation will consider the fair value of Unicom's assets and
liabilities at that future date, including the fair value determination of
nuclear generating stations, and may differ significantly from the amount
recorded in these pro forma financial statements. The pro forma adjustment
also relates to the elimination of accumulated depreciation reflected on
Unicom's books in accordance with purchase accounting as prescribed by GAAP.
As a result of the increased merger pro forma common stock equity balance, the
merger pro forma adjustments include a reversal of the increased regulatory
asset amortization related to the Unicom Pro Forma Adjustments discussed in
Notes 3 and 4.

   8. Reflects the elimination of purchased power and off-system sales
transactions between PECO and Unicom.

   9. Reflects amortization of goodwill over a 40-year period.

   10. Reflects the reclassification of PECO preferred stock dividends and
interest on PECO obligated mandatorily redeemable preferred securities for
consistent presentation.

   11. Reflects the repurchase of approximately $1.0 billion of Unicom's
outstanding common shares and approximately $500 million of PECO's outstanding
common shares prior to closing. PECO's pro forma cash balance as of September
30, 1999 was insufficient to fully fund its repurchase. Accordingly, for pro
forma purposes, it was assumed that PECO would borrow $500 million of long
term debt at an interest rate of approximately 7.25% in order to fund this
transaction. The amount of the borrowing, if any, at the time of consummation
of the merger will depend on PECO's actual cash available at that time.

of the conditions set forth in Section 7.01, or, if on such day any condition
set forth in Section 7.02 or 7.03 has not been satisfied (or, to the extent

Exchange.  The First Step Exchange shall become effective at such time as the

Illinois has issued a certificate of merger in respect of the Second Step
Merger, or at such other time as Newco and the Company shall agree and specify

Merger Effective Time, be the By-laws of the Surviving Corporation, and shall in
any case be amended by inserting the provisions set forth in Exhibit A as

     paid and nonassessable share of Newco Common Stock (the "Parent Exchange
     Ratio").

               (B)  The shares of Newco Common Stock to be issued by Newco upon
          the exchange of shares of Parent Common Stock pursuant to this Section
          2.01(a)(ii) are referred to collectively as "Exchange Consideration".
          As of the Exchange Effective Time, all such shares of Parent Common
          Stock shall be exchanged for Exchange Consideration and such shares of
          Parent Common Stock shall remain outstanding and shall be owned and
          held by Newco, and each holder of a certificate representing any such

the Second Step Merger and without any action on the part of the holder of any

     of Company Common Stock that is owned by the Company or Newco shall no
     longer be outstanding and shall automatically be canceled and retired and
     shall cease to exist, and no Newco Common Stock or other consideration
     shall be delivered or deliverable in exchange therefor.

          (ii) Conversion of Company Common Stock. (A)  Subject to Sections

     and nonassessable shares of Newco Common Stock (the "Company Exchange

<PAGE>

                                                                               7

          conversion of shares of Company Common Stock pursuant to this Section
          2.01(b)(ii) and cash in lieu of fractional shares of Newco Common
          Stock to the extent contemplated by Section 2.02(e) are referred to
          collectively as "Merger Consideration". As of the Merger Effective
          Time, all such shares of Company Common Stock shall no longer be
          outstanding and shall automatically be canceled and retired and shall
          cease to exist, and each holder of a certificate representing any such
          shares of Company Common Stock shall cease to have any rights with
          respect thereto, except the right to receive Merger Consideration upon
          surrender of such certificate in accordance with Section 2.02, without
          interest.

          (iii) Newco Common Stock.  The Newco Common Stock outstanding
     immediately prior to the Merger Effective Time issued as contemplated by
     Section 2.01(a)(ii) shall remain outstanding, without change, after the
     Merger Effective Time, and no Merger Consideration shall be delivered or
     deliverable in exchange therefor.

          (iv)  Dissent Rights.  Notwithstanding anything in this Agreement to
     the contrary, shares ("Company Dissent Shares") of Company Common Stock
     that are outstanding immediately prior to the Merger Effective Time and
     that are held by any person who is entitled to demand and properly demands
     payment of the fair value of such Company Dissent Shares pursuant to, and
     who complies in all respects with, Sections 11.65 and 11.70 of the IBCA
     ("Sections 11.65 and 11.70") shall be converted into the right to receive
     Merger Consideration as provided in Section 2.01(b)(ii), and shall
     thereafter be subject to sale and purchase rights in accordance with
     Sections 11.65 and 11.70.

          SECTION 2.02.  Exchange of Certificates. (a)  Exchange Agent.
Promptly following the Merger Effective Time, Newco shall deposit with such bank
or trust company as may be designated by Newco and reasonably acceptable to
Parent and the Company (the "Exchange Agent"), for the benefit of the holders of
shares of Parent Common Stock and Company Common Stock, for exchange in
accordance with this Article II, through the Exchange Agent, cash equal to the
total aggregate Company Cash Consideration and certificates representing the
shares of Newco Common Stock issuable pursuant to Section 2.01 in exchange for
outstanding Company Certificates or Parent Certificates. Newco shall provide to
the Exchange Agent on a timely basis, as and when needed after the Merger
Effective Time, cash
<PAGE>

                                                                               8

equal to the total aggregate Company Cash Consideration (such shares of Newco
Common Stock and cash, together with any dividends or distributions with respect
thereto, being hereinafter referred to as the "Exchange Fund"). For the purposes
of such deposit, Newco shall assume that there will not be any fractional shares
of Newco Common Stock. Newco shall make available to the Exchange Agent, for
addition to the Exchange Fund, from time to time as needed, cash sufficient to
pay cash in lieu of fractional shares to the extent provided in Section 2.02(e).

          (b)  Exchange Procedures.  As soon as reasonably practicable after the
Merger Effective Time, the Exchange Agent shall mail to each holder of record of
a certificate or certificates that immediately prior to the Exchange Effective
Time represented outstanding shares of Parent Common Stock that were converted
into the right to receive Exchange Consideration (the "Parent Certificates") or
that immediately prior to the Merger Effective Time represented outstanding
shares of Company Common Stock that were converted into the right to receive
Merger Consideration (the "Company Certificates" and, together with the Parent
Certificates, the "Certificates"), in each case, pursuant to Section 2.01, (i) a
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent and the Company may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for Exchange Consideration or Merger Consideration, as the case may be.  Upon
surrender of a Parent Certificate or a Company Certificate for cancelation to
the Exchange Agent, together with such letter of transmittal, duly executed, and
such other documents as may reasonably be required by the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor
Company Cash Consideration and a certificate representing that number of whole
shares of Newco Common Stock (together with cash in lieu of fractional shares),
in each case, that such holder has the right to receive pursuant to the
provisions of this Article II, and the Certificate so surrendered shall
forthwith be canceled. Until such time as a certificate representing Newco
Common Stock is issued to or at the direction of the holder of a surrendered
Company Certificate or Parent Certificate, such Newco Common Stock shall be
deemed not outstanding and shall not be entitled to vote on any matter.  In the
event of a transfer of ownership of Parent Common Stock or Company Common Stock
that is not registered in the transfer records of Parent or the Company, as the
case may be, payment may be
<PAGE>

                                                                               9

made and a certificate representing the appropriate number of shares of Newco
Common Stock may be issued to a person other than the person in whose name the
Certificate so surrendered is registered, if such Certificate shall be properly
endorsed or otherwise be in proper form for transfer and the person requesting
such payment shall pay any transfer or other taxes required by reason of such
payment or the issuance of shares of Newco Common Stock to a person other than
the registered holder of such Certificate or establish to the satisfaction of
Newco that such tax has been paid or is not applicable. Subject to Sections
11.65 and 11.70 of the IBCA (in the case of a Company Certificate), until
surrendered as contemplated by this Section 2.02, each Company Certificate or
Parent Certificate shall be deemed at any time after the Merger Effective Time
or Exchange Effective Time, as applicable, to represent only the right to
receive upon such surrender Merger Consideration or Exchange Consideration, as
applicable, as contemplated by this Section 2.02. No interest shall be paid or
accrue on any cash payable, whether in respect of Exchange Consideration, Merger
Consideration, dividends or otherwise, upon surrender of any Certificate. Any
dividend reinvestment plan, employee stock ownership plan or similar plan of the
Company may be treated as a single holder of Company Common Stock for the
purposes of Section 2.02(e).

          (c)  Distributions with Respect to Unexchanged Shares.  No dividends
or other distributions with respect to Newco Common Stock with a record date
after the Merger Effective Time shall be paid to the holder of any unsurrendered
Company Certificate or Parent Certificate with respect to the shares of Newco
Common Stock issuable upon surrender thereof, and no cash payment in lieu of
fractional shares shall be paid to any such holder pursuant to Section 2.02(e),
until the surrender of such certificate in accordance with this Article II.
Subject to Applicable Law, following surrender of any such Certificate, there
shall be paid to the holder of the certificate representing whole shares of
Newco Common Stock issued in exchange therefor, without interest, (i) at the
time of such surrender, the amount of any cash payable in lieu of a fractional
share of Newco Common Stock to which such holder is entitled pursuant to Section
2.02(e) and the amount of dividends or other distributions with a record date
after the Merger Effective Time theretofore paid with respect to such whole
shares of Newco Common Stock, and (ii) at the appropriate payment date, the
amount of dividends or other distributions with a record date after the Merger
Effective Time but prior to such surrender and a payment date subsequent to such

          (d)  No Further Ownership Rights in Parent Common Stock or Company
Common Stock.  The Exchange Consideration and Merger Consideration issued (and
paid) in accordance with the terms of this Article II upon conversion and
exchange of any shares of Parent Common Stock or Company Common Stock, as the
case may be, shall be deemed to have been issued (and paid) in full satisfaction
of all rights pertaining to such shares of Parent Common Stock or Company Common
Stock, subject, however, to (i) the Surviving Corporation's obligations to pay
or provide for the rights of dissenters and (ii) the Surviving Corporation's
obligation to pay any dividends or make any other distributions with a record
date prior to the Merger Effective Time that may have been declared or made by
the Parent on such shares of Parent Common Stock or the Company on such shares
of Company Common Stock, respectively, in accordance with the terms of this
Agreement or prior to the date of this Agreement and which remain unpaid at the
Merger Effective Time, and after the Merger Effective Time there shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of shares of Parent Common Stock or Company Common Stock that were
outstanding immediately prior to the Merger Effective Time. If, after the Merger
Effective Time, any certificates formerly representing shares of Parent Common
Stock or Company Common Stock, as the case may be, are presented to the
Surviving Corporation or the Exchange Agent for any reason, they shall be
canceled and exchanged as provided in this Article II.

          (e)  No Fractional Shares.  (i)  Except as otherwise agreed to by the
Company and Parent as provided in Section 2.02(e)(v), no certificates or scrip
representing fractional shares of Newco Common Stock shall be issued upon the
conversion of Company Common Stock pursuant to Section 2.01, and such fractional
share interests shall not entitle the owner thereof to vote or to any rights of
a holder of Newco Common Stock.  For purposes of this Section 2.02(e), all
fractional shares to which a single record holder would be entitled shall be
aggregated and calculations shall be rounded to three decimal places.

          (ii) As promptly as practicable following the Merger Effective Time,
the Exchange Agent shall determine the excess of (A) the number of shares of
Newco Common Stock delivered to the Exchange Agent by Newco pursuant to Section
2.02(a) over (B) the aggregate number of whole shares of Newco Common Stock to
be issued to holders of Company Common Stock pursuant to Section 2.02(b) (such
excess being herein called the "Excess Shares").  As soon after the Merger
Effective Time as practicable, the Exchange
<PAGE>

                                                                              11

Agent, as agent for the holders of Company Common Stock, shall sell the Excess
Shares at then prevailing prices on the New York Stock Exchange (the "NYSE"),
all in the manner provided in Section 2.02(e)(iii).

          (iii) The sale of the Excess Shares by the Exchange Agent shall be
executed on the NYSE through one or more member firms of the NYSE and shall be
executed in round lots to the extent practicable.  The proceeds from such sale
or sales available for distribution to the holders of Company Common Stock shall
be reduced by transfer taxes in connection with such sale or sales of the Excess
Shares. Until the net proceeds of such sale or sales have been distributed to
the holders of Company Common Stock entitled thereto, the Exchange Agent shall
hold such proceeds in trust for such holders of Company Common Stock (the
"Common Shares Trust").  The Exchange Agent shall determine the portion of the
Common Shares Trust to which each holder of a Certificate shall be entitled, if
any, by multiplying the amount of the aggregate net proceeds comprising the
Common Shares Trust by a fraction, the numerator of which is the amount of the
fractional share interest in a share of Newco Common Stock to which such holder
is entitled under Section 2.01(b)(ii) (or would be entitled but for this Section
2.02(e)) and the denominator of which is the aggre  gate amount of fractional
interests in a share of Newco Common Stock to which all holders of Company
Common Stock are entitled.

          (iv) As soon as practicable after the determination of the amount of
cash, if any, to be paid to holders of Company Common Stock in lieu of any
fractional share interests in Newco Common Stock, the Exchange Agent shall make
available such amounts, without interest, to such holders entitled to receive
such cash .

          (v)   Notwithstanding anything herein to the contrary, if the Company
and Parent so agree prior to the Closing, Newco may establish a common stock
direct share registration program pursuant to which shareholders would receive a
book entry credit for fractional shares of Newco Common Stock in lieu of cash as
otherwise provided in this Section 2.02(e).  If the Company and Parent agree to
have Newco establish such a program, any reference herein to fractional shares
shall refer to such book entry fractional shares and no cash will be issued for
such shares except as may be provided by such program.  In no event will Newco
issue certificates or script representing fractional shares.

          (f)   Termination of Exchange Fund.  Any portion of the Exchange Fund
that remains undistributed to the holders

                                                                              12

of Parent Common Stock or Company Common Stock for six months after the Merger
Effective Time shall be delivered to Newco, upon demand, and any holder of
Parent Common Stock or Company Common Stock who has not theretofore complied
with this Article II shall thereafter look only to Newco for payment of its
claim for Exchange Consideration or Merger Consideration, as the case may be,
and any dividends or distributions with respect to Newco Common Stock as
contemplated by Section 2.02(c).

          (g)  No Liability.  None of Parent, Newco, the Company or the Exchange
Agent shall be liable to any person in respect of any shares of Newco Common
Stock (or dividends or distributions with respect thereto) or cash from the
Exchange Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar Applicable Law.  If any Company
Certificate or Parent Certificate has not been surrendered prior to five years
after the Merger Effective Time (or immediately prior to such earlier date on
which Merger Consideration or Exchange Consideration or any dividends or
distributions with respect to Newco Common Stock as contemplated by Section
2.02(c)(i) in respect of such Company Certificate or Parent Certificate would
otherwise escheat to or become the property of any Governmental Entity (as
defined in Section 3.05)), any such shares, cash, dividends or distributions in
respect of such Company Certificate shall, to the extent permitted by Applicable
Law, become the property of the Surviving Corporation, free and clear of all
claims or interest of any person previously entitled thereto.

          (h)  Investment of Exchange Fund.  The Exchange Agent shall invest any
cash included in the Exchange Fund, as directed by Newco, on a daily basis.  Any
interest and other income resulting from such investments shall be paid to
Newco.

          (i)  Withholding Rights.  Newco shall be entitled to deduct and
withhold from the consideration otherwise payable to any holder of Parent Common
Stock or Company Common Stock pursuant to this Agreement such amounts as may be
required to be deducted and withheld with respect to the making of such payment
under the Code, or under any provision of state, local or foreign tax law.  To
the extent that amounts are so withheld and paid over to the appropriate taxing
authority, Newco will be treated as though it withheld an appropriate amount of
the type of consideration otherwise payable pursuant to this Agreement to any
holder of Parent Common Stock or Company Common Stock, sold such consideration
for an amount of cash equal to the fair market value of such consideration at
the time
<PAGE>

                                                                              13

of such deemed sale and paid such cash proceeds to the appropriate taxing
authority.

          Section 2.03.  Certain Adjustments.  If after the date hereof and on
or prior to the Closing Date, the outstanding shares of Parent Common Stock or
Company Common Stock shall be changed into a different number of shares by
reason of any reclassification, recapitalization, split-up, combination or
exchange of shares, or any dividend payable in stock or other securities is
declared thereon with a record date within such period, or any similar event
shall occur, the Exchange Consideration and the Merger Consideration will be
adjusted accordingly to provide to the holders of Parent Common Stock and
Company Common Stock, respectively, the same economic effect as contemplated by
this Agreement prior to such reclassification, recapitalization, split-up,
combination, exchange or dividend or similar event.  This provision is not
intended to affect the need for either party to obtain the other party's consent
to take such an action under any other provision of this Agreement.


                                  ARTICLE III

                 Representations and Warranties of the Company

          The Company represents and warrants to Parent and Newco as follows:

          SECTION 3.01.  Organization, Standing and Power. Each of the Company
and each of its subsidiaries (the "Company Subsidiaries") is duly organized,
validly existing and in good standing (with respect to jurisdictions which
recognize the concept of good standing) under the laws of the jurisdiction in
which it is organized and has full corporate power and authority and possesses
all governmental franchises, licenses, permits, authorizations and approvals
necessary to enable it to own, lease or otherwise hold its properties and assets
and to conduct its businesses as conducted as of the date of this Agreement,
other than such franchises, licenses, permits, authorizations and approvals the
lack of which, individually or in the aggregate, has not had and could not
reasonably be expected to have a Material Adverse Effect on the Company (a
"Company Material Adverse Effect"). The Company and each Company Subsidiary is
duly qualified to do business in each jurisdiction where the nature of its
business or their ownership or leasing of its properties make such
qualification necessary, other than such qualifications the lack of which,
individually or in the aggregate, has not had and could not reasonably be














<PAGE>

                                                                              14

expected to have a Material Adverse Effect on the Company (a "Company Material
Adverse Effect"). The Company and each Company Subsidiary is duly qualified to
do business in each jurisdiction where the nature of its business or their
ownership or leasing of its properties make such qualification necessary, other
than such qualifications the lack of which, individually or in the aggregate,
has not had and could not reasonably be expected to have a Company Material
Adverse Effect. The Company has made available to Parent true and complete
copies of the articles of incorporation of the Company, as amended to the date
of this Agreement (as so amended, the "Company Charter"), and the By-laws of the
Company, as amended to the date of this Agreement (as so amended, the "Company
By-laws"), and the comparable charter or organizational documents of each
Company Subsidiary, in each case as amended through the date of this Agreement.

          SECTION 3.02.  Company Subsidiaries; Equity Interests.  (a)  The
letter, dated as of the date of this Agreement, from the Company to Parent and
Newco (the "Company Disclosure Letter") lists each Company Subsidiary and its
jurisdiction of organization and specifies each of the Company Subsidiaries that
is (i) a "public-utility company", a "holding company", a "subsidiary company",
an "affiliate" of any public-utility company, an "exempt wholesale generator" or
a "foreign utility company" within the meaning of Section 2(a)(5), 2(a)(7),
2(a)(8), 2(a)(11), 32(a)(1) or 33(a)(3) of the Public Utility Holding Company
Act of 1935, as amended ("PUHCA"), respectively, (ii) a "public utility" within
the meaning of Section 201(e) of the Federal Power Act (the "Power Act") or
(iii) a "qualifying facility" within the meaning of the Public Utility
Regulatory Policies Act of 1978, as amended ("PURPA"), or that owns such a
qualifying facility.  All the outstanding shares of capital stock of each
Company Subsidiary have been validly issued and are fully paid and nonassessable
and, except as set forth in the Company Disclosure Letter, are owned by the
Company, by another Company Subsidiary or by the Company and another Company
Subsidiary, free and clear of all pledges, liens, charges, mortgages,
encumbrances and security interests of any kind or nature whatsoever
(collectively, "Liens").

          (b)  Except for its interests in the Company Subsidiaries and except
for the ownership interests set forth in the Company Disclosure Letter or
interests acquired after the date of this Agreement without violating any
covenant of this Agreement, the Company does not own, directly or indirectly,
any capital stock, membership interest, partnership interest, joint venture
interest or other equity interest with a fair market value as of the date of
this Agreement in excess of $500,000 in any person, as reasonably determined by
the Company.

          (b)  Except as set forth in clause (a) of this Section 3.03 or in the
Company Disclosure Letter, at the close of business on August 31, 1999, no

subject to or issued in violation of any purchase option, call option, right of
first refusal, preemptive right, subscription right or any similar right under
any provision of the IBCA, the Company Charter, the Company By-laws or any
Contract (as defined in Section 3.05) to which the Company is a party or
otherwise bound.

          (d)  There are not any bonds, debentures, notes or other indebtedness
of the Company having the right to vote (or convertible into, or exchangeable
for, securities having the right to vote) on any matters on which holders of
Company Common Stock may vote ("Voting Company Debt").

          (e)  Except as set forth in clause (a) of this Section 3.03 or in the
Company Disclosure Letter, as of the date of this Agreement, there are not any

Subsidiary is a party or by which any of them is bound (i) obligating the
Company or any Company Subsidiary to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock or other equity
interests in, or any security convertible or exercisable for or exchangeable
into any capital stock of or other equity interest in, the Company or of any
Company Subsidiary or any Voting Company Debt or (ii) obligating the Company or

          (g)  The Company has delivered to Parent a complete and correct copy
of the Company Rights Agreement, as amended to the date of this Agreement.

          SECTION 3.04.  Authority; Execution and Delivery; Enforceability.  (a)
The Company has all requisite corporate power and authority to execute and
deliver this Agreement and to consummate the Transactions.  The execution and
delivery by the Company of this Agreement and the consummation by the Company of
the Transactions have been duly authorized by all necessary corporate action on
the part of the Company, subject, in the case of the Second Step Merger, to
receipt of the Company Shareholder Approval (as defined in Section 3.04(c)).
The Company has duly executed and delivered this Agreement, and this Agreement
constitutes its legal, valid and binding obligation, enforceable against it in
accordance with its terms.

          (b)  The Board of Directors of the Company (the "Company Board"), at a
meeting duly called and held, duly and unanimously adopted resolutions (i)
approving this Agreement, the Merger and the other Transactions, (ii)
determining that the terms of the Second Step Merger and the other Transactions
are fair to and in the best interests of the Company and its shareholders and
(iii) directing that this Agreement be submitted to a vote of the Company's
shareholders and recommending that they approve this Agreement.  Such
resolutions are sufficient to render inapplicable to Parent and Newco and this
Agreement, to the extent otherwise applicable, the Merger and the other
Transactions the provisions of Sections 7.85 and 11.75 of the IBCA.  To the
Company's knowledge, no other state
<PAGE>

                                                                              17

to the Company with respect to this Agreement, the Second Step Merger or any
other Transaction.

          (c)  The only vote of holders of any class or series of Company
securities necessary to approve and adopt this Agreement and the Second Step
Merger is the approval of this Agreement by the holders of at least two-thirds
of the shares of outstanding Company Common Stock entitled to vote (the "Company
Shareholder Approval").  The affirmative vote of the holders of Company Common
Stock, or any of them, is not necessary to consummate any Transaction other than
the Second Step Merger.

          SECTION 3.05.  No Conflicts; Consents. (a)  Except as set forth in the
Company Disclosure Letter, the execution and delivery by the Company of this
Agreement does not, and the consummation of the Merger and the other
Transactions and compliance with the terms hereof and thereof will not, conflict
with, or result in any violation of or default (with or without notice or lapse
of time, or both) under, or give rise to a right of termination, consent,
approval, cancelation or acceleration of any obligation or to loss of a material
benefit under, or to increased, additional, accelerated or guaranteed rights or
entitlements of any person under, or result in the creation of any Lien upon any

provision of (i) the Company Charter, the Company By-laws or the comparable
charter or organizational documents of any Company Subsidiary, (ii) any loan or
credit agreement, contract, lease, license, indenture, note, bond, agreement,

referred to in Section 3.05(b), any judgment, order or decree ("Judgment") or
statute, law, ordinance, rule or regulation ("Applicable Law") or writ, permit
or license applicable to the Company or any Company Subsidiary or their
respective properties or assets (other than immaterial consents, approvals,
licenses, permits, orders, authorizations, registrations, declarations or
filings, including with respect to communications systems, zoning, name changes,
occupancy and similar routine regulatory approvals), other than, in the case of
clauses (ii) and (iii) above, any such items that, individually or in the

Material Adverse Effect.

               (c)  The Company and the Company Board have taken all action
     necessary to (i) render the Company Rights

               SECTION 3.06.  SEC Documents; Undisclosed Liabilities.  The
     Company and the Company Subsidiaries have filed all reports, schedules,
     forms, statements and other documents required to be filed by the Company
     or any Company Subsidiary with the SEC since January 1, 1998 (the "Company
     SEC Documents"). Each Company SEC Document complied in all material
     respects as of its respective date with the requirements of the Exchange
     Act or the Securities Act of 1933, as amended (the "Securities Act"), as
     the case may be, and the rules and regulations of the SEC promulgated
     thereunder applicable to such Company SEC Document, and except to the
     extent that information contained in any Company SEC Document has been
     revised or superseded by a later filed Company SEC Document, does not
     contain any untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary in order to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading. The consolidated financial statements of the Company
     included in the Company SEC Documents comply as to form in all material
     respects with applicable accounting requirements and the published rules
     and regulations of the SEC with respect thereto, have been prepared in
     accordance with generally accepted accounting principles ("GAAP") (except,
     in the case of unaudited statements, as permitted by Form 10-Q of the SEC)
     applied on a consistent basis during the periods involved (except as may be
     indicated in the notes thereto) and fairly present the consolidated
     financial position of the Company and its consolidated subsidiaries as of
     the dates thereof and the consolidated results of their operations and cash
     flows for the periods then ended (subject, in the case of unaudited
     statements, to normal year-end audit adjustments). Except as set forth in
     the Filed Company SEC Documents (as defined in Section 3.08) or the Company
     Disclosure Letter or incurred after the date hereof in the usual, regular
     and ordinary course of business in substantially the same manner as
     previously conducted and not prohibited by this Agreement, neither the
     Company nor any Company Subsidiary has any liabilities or obligations of
     any nature (whether accrued, absolute, contingent or
<PAGE>

                                                                              20

     otherwise) required by GAAP to be set forth on a consolidated balance sheet
     of the Company and its consolidated subsidiaries or in the notes thereto
     and that, individually or in the aggregate, could reasonably be expected to
     have a Company Material Adverse Effect.

               SECTION 3.07.  Information Supplied.  None of the information
     supplied or to be supplied by the Company for inclusion or incorporation by
     reference in (i) the registration statement on Form S-4 to be filed with
     the SEC by Newco in connection with the Share Issuance (the "Form S-4")
     will, at the time the Form S-4 is filed with the SEC, at any time it is
     amended or supplemented or at the time it becomes effective under the
     Securities Act, contain any untrue statement of a material fact or omit to
     state any material fact required to be stated therein or necessary to make

     material fact required to be stated therein or necessary in order to make
     the statements therein, in light of the circumstances under which they are
     made, not misleading. The Proxy Statement will comply as to form in all
     material respects with the requirements of the Exchange Act and the rules

     effect or development that, individually or in the aggregate, has had or
     could reasonably be expected to have a Company Material Adverse Effect,
     other than events, changes, effects and developments relating to the
     economy in general or to the Company's industry in general and not
     specifically relating to the Company or any Company Subsidiary; and

          (b)  from December 31, 1998 to the date of this Agreement, the Company
     has conducted its business only in

     the ordinary course, and during such period there has not been:

               (i)   any declaration, setting aside or payment of any dividend
          or other distribution (whether in cash, stock or property) with
          respect to any Company Common Stock or any repurchase for value by the
          Company of any Company Common Stock;

               (ii)  any split, combination or reclassification of any Company
          Common Stock or any issuance or the authorization of any issuance of
          any other securities in respect of, in lieu of or in substitution for
          shares of Company Common Stock; or

               (iii) any change in accounting methods, principles or practices
          by the Company or any Company Subsidiary materially affecting the
          consolidated assets, liabilities or results of operations of the

     Subsidiary has timely filed, or has caused to be timely filed on its
     behalf, all Tax Returns required to be filed by it (or requests for
     extensions to file such Tax Returns have been timely filed and granted and
     have not expired), and all such Tax Returns are true, complete and
     accurate, except to the extent any failure to file or any inaccuracies in
     any filed Tax Returns would not, individually or in the aggregate, have a
     Company Material Adverse Effect. All Taxes shown to be due on such Tax
     Returns, or otherwise owed by the Company or any Company Subsidiary, have
     been timely paid, except to the extent that any failure to pay,
     individually or in the aggregate, has not had and could not reasonably be
     expected to have a Company Material Adverse Effect.

               (b)  Except as set forth in the Company Disclosure Letter, the
     most recent financial statements contained in the Filed Company SEC
     Documents reflect an adequate reserve for all current Taxes payable by the
     Company and the Company Subsidiaries (in addition to any reserve for
     deferred Taxes established to reflect timing differences between book and
     Tax income) for all Taxable periods and portions thereof through the date
     of such financial statements. Except as set forth in the Company Disclosure
     Letter, no deficiency with respect to any Taxes has, to the best knowledge
     of the Company, been proposed, asserted or assessed against the Company or
     any Company Subsidiary, and no requests for waivers of the time to assess
     any such Taxes are pending,
<PAGE>

                                                                              22

     except to the extent any such deficiency or request for waiver,
     individually or in the aggregate, has not had and could not reasonably be
     expected to have a Company Material Adverse Effect.

          (c)  The Federal income Tax Returns of the Company and each Company
     Subsidiary consolidated in such Returns have been examined by and settled
     with the United States Internal Revenue Service for all years through 1995.
     Except as set forth in the Company Disclosure Letter, all material
     assessments for Taxes due with respect to such completed and settled
     examinations or any concluded litigation have been fully paid.

          (d)  There are no material Liens for Taxes (other than for current
     Taxes not yet due and payable) on the assets of the Company or any Company
     Subsidiary. Except as set forth in the Company Disclosure Letter, neither
     the Company nor any Company Subsidiary is bound by any agreement with
     respect to Taxes.

          (e)  The Company and each Company Subsidiary have complied with all
     applicable statutes, laws, ordinances, rules and regulations relating to
     the payment and withholding of taxes (including withholding of taxes
     pursuant to Sections 1441, 1442, 3121 and 3402 of the Code or similar
     provisions under any Federal, state or local laws, domestic and foreign)
     and have, within the time and in the manner prescribed by law, withheld
     from and paid over to the proper governmental authorities all amounts
     required to be so withheld and paid over under applicable laws, except to
     the extent that any failure to withhold or to pay, individually or in the
     aggregate, has not had and could not reasonably be expected to have a
     Company Material Adverse Effect.

          (f)  The Company knows of no fact and neither the Company nor any
     Company Subsidiary has taken or agreed to take any action that could
     reasonably be expected to prevent (i) the Merger from constituting
     transactions described in Section 351 of the Code or (ii) the Second Step
     Merger from constituting a transaction described in Section 368(a) of the
     Code.

<PAGE>

                                                                              23

          SECTION 3.10.  Absence of Changes in Benefit Plans.  Except as
     disclosed in the Company Disclosure Letter, from December 31, 1998 to the
     date of this Agreement, there has not been any adoption or amendment in any
     material respect by the Company or any Company Subsidiary of (a) any
     collective bargaining agreements, (b) any bonus, pension, profit sharing,
     deferred compensation, incentive compensation, stock ownership, stock
     purchase, stock option, phantom stock, retirement, vacation, severance,
     disability, death benefit, hospitalization, medical or other plan, program,
     policy, arrangement or understanding (whether or not legally binding)
     providing benefits to any current or former employee, officer or director
     of the Company or any Company Subsidiary or any beneficiary or dependent
     thereof, that is sponsored or maintained by the Company or any Company
     Subsidiary or to which the Company or any Company Subsidiary contributes

     disclosed in the Company Disclosure Letter, as of the date of this
     Agreement there are not any employment, consulting, indemnification,
     change-of-control, severance or termination agreements or arrangements
     between the Company or any Company Subsidiary and any current or former
     employee, officer or director of the Company or any Company Subsidiary

          SECTION 3.11.  ERISA Compliance; Excess Parachute Payments.  (a)  The
     Company Disclosure Letter includes a complete list of all material Company
     Benefit Plans and Company Employment Arrangements as of the date of this

     Company Employment Arrangement, the Company has delivered to Parent true,
     complete and correct copies of (i) each such Company Benefit Plan or

     any such report was required), including all schedules and

                                                                              24

     attachments thereto, (iii) the most recent summary plan description (if a
     summary plan description is required) and all summaries of material
     modifications thereto, (iv) each trust agreement, group annuity contract or
     other funding vehicle relating to any such Company Benefit Plan or Company
     Employment Arrangement, (v) the most recent actuarial report or valuation
     relating thereto and (vi) the most recent determination letters issued by
     the Internal Revenue Service with respect to Company Benefit Plans that are

     Sections 401(a) and 501(a), respectively, of the Code ("Qualified Plans")
     and letters of recognition of exemption with respect to any Company Benefit
     Plan or related trust that is intended to meet the requirements of
     Section 501(c)(9) of the Code.

               (b)  With respect to the Company Benefit Plans and Company
     Employment Arrangements, individually and in the aggregate, no event has
     occurred and, to the knowledge of the Company, there exists no condition or
     set of circumstances, in connection with which the Company or any Company
     Subsidiary could be subject to any liability that has had or could
     reasonably be expected to have a Company Material Adverse Effect (except
     liability for benefits claims and funding obligations payable in the
     ordinary course) under the Employee Retirement Income Security Act of 1974,
     as amended ("ERISA"), the Code or any other applicable law. For purposes of
     this Section 3.11(b), the term "Company Benefit Plan" shall also include
     any employee benefit plan within the meaning of Section 3(3) of ERISA that,
     within the last six years, was sponsored or maintained by any entity which
     would be treated under Section 414 of the Code as a single employer with
     the Company or any Company Subsidiary or to which any such entity
     contributed or was obligated to contribute.

               (c)  Each Company Benefit Plan and each Company Employment
     Arrangement has been administered in accordance with its terms except for
     any failures so to administer any Company Benefit Plan or Company
     Employment Arrangement as have not had and could not reasonably be expected
     to have, individually or in the aggregate, a Company Material Adverse
     Effect. The Company, all Company Subsidiaries and all the Company Benefit
     Plans and Company Employment Arrangements are in compliance with the
     applicable provisions of ERISA, the Code and all other applicable laws and
     the rules and regulations thereunder and the terms of all applicable
     collective bargaining agreements, except for any failures to be in such
     compliance as have not had and could not reasonably be expected to have,
     individually or in the aggregate, a Company Material Adverse Effect. Except
     as
<PAGE>

                                                                              25


     disclosed in the Company Disclosure Letter, there are no pending or, to
     the knowledge of the Company, threatened or anticipated claims under or
     with respect to any Company Benefit Plan or Company Employment Arrangement
     by or on behalf of any current or former employee, officer or director, or
     dependent or beneficiary thereof, or otherwise (other than routine claims
     for benefits).

               (d)  Except as disclosed in the Company Disclosure Letter, (i) no
     current or former employee, officer or director of the Company or any
     Company Subsidiary will be entitled to any additional rights or benefits or
     any acceleration of the time of payment or vesting of any benefits under
     any Company Benefit Plan or Company Employment Arrangement, and no trustee
     under any "rabbi trust", or similar arrangement maintained in connection
     with any Company Benefit Plan or Company Employment Arrangement will be
     entitled to any payment, as a result (either alone or upon the occurrence
     of any additional or further acts or events) of the execution of this
     Agreement or the consummation, announcement or other actions relating to
     the Transactions and (ii) no amount payable to any current or former
     employee, officer or director of the Company or any Company Subsidiary will
     fail to be deductible by reason of Section 280G of the Code.

               (e)  Each Company Benefit Plan intended to be a Qualified Plan
     has received a favorable determination letter from the Internal Revenue
     Service that it is so qualified and nothing has occurred since the date of
     such letter that could reasonably be expected to affect the qualified
     status of such Company Benefit Plan.

               (f)  The aggregate accumulated benefit obligations of each
     Company Benefit Plan subject to Title IV of ERISA (as of the date of the
     most recent actuarial valuation prepared for such Company Benefit Plan) do
     not exceed the fair market value of the assets of such plan (as of the date
     of such valuation).

               (g)  All contributions and other payments required to have been
     made for any completed historical period by the Company or any Company
     Subsidiary to any Company Benefit Plan or Company Employment Arrangement
     (or to any person pursuant to the terms thereof) have been timely made or
     paid in full, or, to the extent not required to be made or paid for such
     period, have been reflected in the consolidated financial statements of the
     Company.

               (h)  Except as disclosed in the Company Disclosure Letter, no
     Company Benefit Plan is a multiemployer plan
<PAGE>

                                                                              26

     within the meaning of Section 4001(a)(3) of ERISA, and none of the Company
     or any Company Subsidiary has, at any time during the last six years,
     contributed to or been obligated to contribute to any such multiemployer
     plan. For purposes of the representations and warranties made in the last
     sentence of Section 3.11(c) and in Sections 3.11(e) and (f), the term
     "Company Benefit Plan" shall be deemed to exclude any such multiemployer
     plan.

          SECTION 3.12.  Litigation.  Except as disclosed in the Filed Company
     SEC Documents or in the Company Disclosure Letter, there is no suit, action
     or proceeding pending or, to the knowledge of the Company, threatened
     against the Company or any Company Subsidiary that, individually or in the
     aggregate, has had or could reasonably be expected to have a Company
     Material Adverse Effect, nor is there any Judgment outstanding against the
     Company or any Company Subsidiary that has had or could reasonably be
     expected to have a Company Material Adverse Effect.

          SECTION 3.13.  Compliance with Applicable Laws; Permits.  (a)  Except
     as disclosed in the Filed Company SEC Documents or in the Company
     Disclosure Letter, the Company and the Company Subsidiaries are in
     compliance with the terms of all Company Permits (as defined in Section
     3.13(b)) and all Applicable Laws, except for instances of noncompliance
     that, individually and in the aggregate, have not had and could not
     reasonably be expected to have a Company Material Adverse Effect. This
     Section 3.13 does not relate to matters with respect to Taxes, which are
     the subject of Section 3.09, Environmental Laws, which are the subject of
     Section 3.17, benefits plans, which are the subject of Section 3.11 and the
     operation of nuclear power plants, which are the subject of Section 3.19.

          (b)  Except as disclosed in the Filed Company SEC Documents or in the
     Company Disclosure Letter, the Company and the Company Subsidiaries own or
     have sufficient rights and consents to use under existing franchises,
     permits, easements, leases, and license agreements (the "Company Permits")
     all properties, rights and assets necessary for the conduct of their
     business and operations as currently conducted, except where the failure to
     own or have sufficient rights to such properties, rights and assets,
     individually or in the aggregate, have not had and could not reasonably be
     expected to have a Company Material Adverse Effect. Except as provided in
     the Illinois Electric Customer Choice and Rate Relief Law of 1997, to the
     knowledge of the Company, no other private corporation can commence
     electric public utility operations in any part of the respective
     territories now served by the Company or any

                                                                              27

     Company Subsidiary, without obtaining a certificate of public convenience
     and necessity from the applicable state utility commission.

     investment banker, financial advisor or other person, other than
     Wasserstein Perella & Co. and Goldman Sachs & Co., the fees and expenses of
     which will be paid by the Company, is entitled to any broker's, finder's,
     financial advisor's or other similar fee or commission in connection with
     the Second Step Merger and the other Transactions based upon arrangements
     made by or on behalf of the Company.

          SECTION 3.15.  Opinion of Financial Advisor.  The Company has received
     the opinion of Wasserstein Perella & Co., dated as of January 6, 2000, to
     the effect that, as of such date, the Company Merger Consideration is fair
     to the holders of Company Common Stock from a financial point of view, a
     signed copy of which opinion has been delivered to Parent.

          SECTION 3.16.  Year 2000.  The Company SEC Documents fairly summarize
     the status of the Company's computer applications and components,
     modification or readiness plan, communications with suppliers and vendors,
     contingency plans and estimated cost of remediation as they relate to the
     Year 2000 issue. The Company has made available to Parent copies of all
     correspondence between the Company and its third party suppliers and
     vendors concerning their Year 2000 compliance.

          SECTION 3.17.  Environmental Matters. (a) Compliance. Except as set
     forth in the Filed Company SEC Documents or in the Company Disclosure
     Letter, the Company and each of the Company Subsidiaries is and has been in
     compliance with all applicable Environmental Laws (as defined below),
     except where the failure to so comply, individually or in the aggregate,
     has not had and could not reasonably be expected to have a Company Material
     Adverse Effect.

          (b)  Environmental Permits.  Except as set forth in the Filed Company
     SEC Documents or in the Company Disclosure Letter, (i) the Company and each
     of the Company Subsidiaries has obtained or has applied for all
     Environmental Permits (as defined below) necessary for the construction of
     their facilities or the conduct of their operations, except where the
     failure to so obtain, individually or in the aggregate, has not had and
     could not reasonably be expected to have a Company Material Adverse
<PAGE>

                                                                              28

     Effect and (ii) all such Environmental Permits are in good standing or,
     where applicable, a renewal application has been timely filed and is
     pending agency approval, except where the failure of such Environmental
     Permits to be in good standing or to have filed a renewal application on a
     timely basis has not had and could not reasonably be expected to have,
     individually or in the aggregate, a Company Material Adverse Effect.

          (c)  Environmental Claims.  Except as set forth in the Filed Company
     SEC Documents or in the Company Disclosure Letter, there are no
     Environmental Claims (as defined below) that have had or could reasonably
     be expected to have, individually or in the aggregate, a Company Material
     Adverse Effect, pending or, to the knowledge of the Company, threatened
     against the Company or any of the Company Subsidiaries.

          (d)  Releases.  Except as set forth in the Filed Company SEC Documents
     or in the Company Disclosure Letter, there have been no Releases (as

     Company or any of the Company Subsidiaries, except for any Environmental
     Claim which, individually or in the aggregate, has not had and could not
     reasonably be expected to have a Company Material Adverse Effect.

          (e)  Assumed and Retained Liabilities.  Except as disclosed in the
     Filed Company SEC Documents or in the Company Disclosure Letter, none of
     the Company or the Company Subsidiaries has retained or assumed either
     contractually or by operation of law any liabilities or obligations that
     could reasonably be likely to form the basis for any Environmental Claim,
     which has had and could reasonably be expected to have, individually or in
     the aggregate, a Company Material Adverse Effect.

obligating Parent or any Parent Subsidiary to issue, deliver or sell, or cause
to be issued, delivered or sold, additional shares of capital stock or other
equity interests in, or any security convertible or exercisable for or
exchangeable into any capital stock of or other equity interest in, Parent or of
any Parent Subsidiary or any Voting Parent Debt or (ii) obligating Parent or any

          SECTION 4.04.  Authority; Execution and Delivery; Enforceability.  (a)
Each of Parent and Newco has all requisite corporate power and authority to
execute and deliver this Agreement and to consummate the Transactions. The
execution and delivery by each of Parent and Newco of this Agreement and the
consummation by it of the Transactions have been duly authorized by all
necessary corporate action on the part of Parent and Newco, subject (i) in the
case of the Merger and the Share Issuance, to receipt of the Parent Shareholder
Approval (as defined in Section 4.04(c)) and (ii) adoption by Parent, as sole
shareholder of Newco, of this Agreement.  Each of Parent and Newco has duly
executed and delivered this Agreement, and this Agreement constitutes its legal,
valid and binding obligation, enforceable against it in accordance with its
terms.

          (b)  The Board of Directors of Parent (the "Parent Board"), at a
meeting duly called and held, duly and unanimously adopted resolutions (i)
approving this Agreement, the Merger, the Share Issuance and the other
Transactions, (ii) determining that the terms of the Merger, the Share Issuance
and the other Transactions are fair to and in the best interests of Parent and
its shareholders and (iii) directing that this Agreement be submitted to a vote
of Parent's shareholders and recommending that they adopt this Agreement and
approve the Share Issuance.  Such resolutions are sufficient to render
inapplicable to this Agreement,  the Merger, the Share Issuance and the other
Transactions, to the extent otherwise applicable, the provisions of Subchapters
D (Section 2538), E, F, G, H, I and J of Chapter 25 of the PBCL and (ii) the
provisions of Sections 508 and 509 of the Parent Charter.  To Parent's
knowledge, no other state takeover statute or similar statute or regulation
applies or purports to apply to Parent or Newco with respect to this Agreement,
the Merger, the Share Issuance or any other Transaction.

          (c)  The only vote of holders of any class or series of Parent
securities necessary to approve and adopt this Agreement, the Merger, the Share
Issuance and the other Transactions is the adoption of this Agreement by the
affirmative vote of a majority of the votes cast by all holders of Parent Common
Stock entitled to vote (collectively, the "Parent Shareholder Approval").  The
affirmative vote of the holders of Parent Capital Stock, or any of them,
<PAGE>

                                                                              37

is not necessary to consummate any Transaction other than the Share Issuance and
the Merger.

          SECTION 4.05.  No Conflicts; Consents. (a)  Except as set forth in the
Parent Disclosure Letter, the execution and delivery by each of Parent and Newco
of this Agreement does not, and the consummation of the Merger, the Share
Issuance and the other Transactions and compliance with the terms hereof and
thereof will not, conflict with, or result in any violation of or default (with
or without notice or lapse of time, or both) under, or give rise to a right of
termination, consent, approval, cancelation or acceleration of any obligation or
to loss of a material benefit under, or to increased, additional, accelerated or
guaranteed rights or entitlements of any person under, or result in the creation
of any Lien upon any of the properties or assets of Parent or any Parent
Subsidiary under, any provision of (i) Parent Charter, Parent By-laws or the
comparable charter or organizational documents of any Parent Subsidiary, (ii)
any Contract to which Parent or any Parent Subsidiary is a party or by which any
of their respective properties or assets is bound or (iii) subject to the
filings and other matters referred to in Section 4.05(b), any Judgment or
Applicable Law or writ, permit or license applicable to Parent or any Parent
Subsidiary or their respective properties or assets (other than immaterial
consents, approvals, licenses, permits, orders, authorizations, registrations,
declarations or filings, including with respect to communications systems,
zoning, name changes, occupancy and similar routine regulatory approvals), other
than, in the case of clauses (ii) and (iii) above, any such items that,
individually or in the aggregate, have not had and could not reasonably be
expected to have a Parent Material Adverse Effect.

          (b)  No Consent of, action by or in respect of, or registration,
declaration or filing with, or notice to, any Governmental Entity is required to
be obtained or made by or with respect to Parent or any Parent Subsidiary in
connection with the execution, delivery and performance of this Agreement or the
consummation of the Transactions, other than (i) compliance with and filings
under the HSR Act, (ii) the filing with the SEC of (A) the Form S-4 and the
Proxy Statement and (B) such reports under the Exchange Act, as may be required
in connection with this Agreement, the Merger and the other Transactions, (iii)
the filing of the Articles of Exchange, Pennsylvania Articles of Merger and the
Charter Amendment with the Department of State of the Commonwealth of
Pennsylvania, the filing of the Illinois Articles of Merger with, and issuance
of a certificate of merger by, the Secretary of State of the State of Illinois

                                                                              38

and the filing of appropriate documents with the relevant authorities of the
other jurisdictions in which the Company is qualified to do business, (iv)
notice to, and the consent and approval of, FERC under the Power Act, (v) notice
to, and the consent and approval of, the NRC under the Atomic Energy Act, (vi)

legally required to be obtained, the "Parent Required Statutory Approvals").

          SECTION 4.06.  SEC Documents; Undisclosed Liabilities.  Parent has
filed all reports, schedules, forms, statements and other documents required to
be filed by Parent with the SEC since January 1, 1998 (the "Parent SEC
Documents").  Each Parent SEC Document complied in all material respects as of
its respective date with the requirements of the Exchange Act or the Securities
Act, as the case may be, and the rules and regulations of the SEC promulgated
thereunder applicable to such Parent SEC Document, and except to the extent that
information contained in any Parent SEC Document has been revised or superseded
by a later filed Parent SEC Document, does not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading.  The consolidated financial
statements of Parent included in the Parent SEC Documents comply as to form in
all material respects with applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto, have been prepared in
accordance with GAAP (except, in the case of unaudited statements, as permitted
by Form 10-Q of the SEC) applied on a consistent basis during the periods
involved (except as may be indicated in the notes thereto) and fairly present
the consolidated financial position of Parent and its consolidated subsidiaries
as of the dates thereof and the consolidated results of their operations and
cash flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments).  Except as set forth in the
Filed Parent SEC Documents (as defined in Section 4.08) or the Parent Disclosure
Letter or incurred after the date hereof in the usual, regular and ordinary
course of business in substantially the same manner as previously conducted and
not prohibited by this Agreement,
<PAGE>

                                                                              39

neither Parent nor any Parent Subsidiary has any liabilities or obligations of
any nature (whether accrued, absolute, contingent or otherwise) required by GAAP
to be set forth on a consolidated balance sheet of Parent and its consolidated
subsidiaries or in the notes thereto and that, individually or in the aggregate,
could reasonably be expected to have a Parent Material Adverse Effect. None of
the Parent Subsidiaries is, or has at any time since January 1, 1998 been,
subject to the reporting requirements of Sections 13(a) and 15(d) of the
Exchange Act.

          SECTION 4.07.  Information Supplied.  None of the information supplied
or to be supplied by Parent or Newco for inclusion or incorporation by reference
in (i) the Form S-4 will, at the time the Form S-4 is filed with the SEC, at any
time it is amended or supplemented or at the time it becomes effective under the
Securities Act, contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading, or (ii) the Proxy Statement will, at the date
it is first mailed to the Company's shareholders or Parent's shareholders or at
the time of the Company Shareholders Meeting or the Parent Shareholders Meeting,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading.  The Form S-4 will comply as to form in all material respects with
the requirements of the Securities Act and the rules and regulations thereunder,
except that no representation is made by Parent or Newco with respect to
statements made or incorporated by reference therein based on information
supplied by or on behalf of the Company for inclusion or incorporation by
reference therein.

          SECTION 4.08.  Absence of Certain Changes or Events.  Except as
disclosed in the Parent SEC Documents filed and publicly available prior to the
date of this Agreement (the "Filed Parent SEC Documents") or in the Parent
Disclosure Letter:

          (a)  since December 31, 1998, there has not been any event, change,
effect or development that, individually or in the aggregate, has had or could
reasonably be expected to have a Parent Material Adverse Effect, other than
events, changes, effects and developments relating to the economy in general or
to Parent's industry in general and not specifically relating to Parent or any
Parent Subsidiary; and
<PAGE>

                                                                              40

          (b)  from December 31, 1998 to the date of this Agreement, Parent has
conducted its business only in the ordinary course, and during such period there
has not been:

          (i)   any declaration, setting aside or payment of any dividend or
     other distribution (whether in cash, stock or property) with respect to any
     Parent Capital Stock or any repurchase for value by Parent of any Parent
     Capital Stock;

          (ii)  any split, combination or reclassification of any Parent Capital
     Stock or any issuance or the authorization of any issuance of any other
     securities in respect of, in lieu of or in substitution for shares of
     Parent Capital Stock; or

          (iii) any change in accounting methods, principles or practices by
     Parent or any Parent Subsidiary materially affecting the consolidated
     assets, liabilities or results of operations of Parent, except insofar as
     may have been required by a change in GAAP.

          SECTION 4.09.  Taxes.  (a)  Each of Parent and each Parent Subsidiary
has timely filed, or has caused to be timely filed on its behalf, all Tax
Returns required to be filed by it (or requests for extensions to file such Tax
Returns have been timely filed and granted and have not expired), and all such
Tax Returns are true, complete and accurate, except to the extent any failure to
file or any inaccuracies in any filed Tax Returns would not, individually or in
the aggregate, have a Parent Material Adverse Effect.  All Taxes shown to be due
on such Tax Returns, or otherwise owed by Parent or any Parent Subsidiary, have
been timely paid, except to the extent that any failure to pay, individually or
in the aggregate, has not had and could not reasonably be expected to have a
Parent Material Adverse Effect.

          (b)  Except as set forth in the Parent Disclosure Letter, the most
recent financial statements contained in the Filed Parent SEC Documents reflect
an adequate reserve for all current Taxes payable by Parent and the Parent
Subsidiaries (in addition to any reserve for deferred Taxes established to
reflect timing differences between book and Tax income) for all Taxable periods
and portions thereof through the date of such financial statements.  Except as
set forth in the Parent Disclosure Letter, no deficiency with respect to any
Taxes has, to the best knowledge of Parent,  been proposed, asserted or assessed
against Parent or any Parent Subsidiary, and no requests for waivers of the time
to assess any such Taxes are pending, except to the
<PAGE>

                                                                              41

extent any such deficiency or request for waiver, individually or in the
aggregate, has not had and could not reasonably be expected to have a Parent
Material Adverse Effect.

          (c)  The Federal income Tax Returns of Parent and each Parent
Subsidiary consolidated in such Returns have been examined by and settled with
the United States Internal Revenue Service for all years through 1990.  Except

Federal, state or local laws, domestic and foreign) and have, within the time
and in the manner prescribed by law, withheld from and paid over to the proper
governmental authorities all amounts required to be so withheld and paid over

expected to have a Parent Material Adverse Effect.

          (f)  Parent knows of no fact and neither Parent nor any Parent
Subsidiary has taken or agreed to take any action that could reasonably be

          SECTION 4.11.  ERISA Compliance; Excess Parachute Payments.  (a)  The
Parent Disclosure Letter includes a complete list of all material Parent Benefit
Plans and Parent Employment Arrangements as of the date of this Agreement.  With
respect to each Parent Benefit Plan (other than a multiemployer plan within the
meaning of Section 4001(a)(3) of ERISA) and Parent Employment Arrangement,
Parent has delivered to the Company true, complete and correct copies of (i)
each such Parent Benefit Plan or Parent Employment Arrangement (or, in the case
of any unwritten plan or arrangement, a description thereof), (ii) the most
recent annual report on the applicable Form 5500 series filed with the Internal
Revenue Service (if any such report was required), including all schedules and
attachments thereto, (iii) the most recent summary plan description (if a
summary plan description is required) and all summaries of material
modifications thereto, (iv) each trust agreement, group annuity contract or
other funding vehicle relating to any such Parent Benefit Plan or Parent
Employment Arrangement, (v) the most recent actuarial report or valuation

Arrangements, individually and in the aggregate, no event has occurred and, to

Parent, there exists no condition or set of circumstances, in connection with
which Parent or any Parent Subsidiary could be subject to any liability that has
had or could reasonably be expected to have a Parent Material Adverse Effect
(except liability for benefits claims and funding obligations payable in the
ordinary course) under ERISA, the Code or any other applicable law. For purposes
of this Section 4.11(b), the term "Parent Benefit Plan" shall also include any
employee benefit plan within the meaning of Section 3(3) of ERISA that, within
the last six years, was sponsored or maintained by any entity which would be
treated under Section 414 of the Code as a single employer with Parent or any
Parent Subsidiary or to which any such entity contributed or was obligated to
contribute.

          (c)  Each Parent Benefit Plan and each Parent Employment Arrangement
has been administered in accordance with its terms except for any failures so to
administer any Parent Benefit Plan or Parent Employment Arrangement as have not
had and could not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect.  Parent, all Parent Subsidiaries
and all the Parent Benefit Plans and Parent Employment Arrangements are in
compliance with the applicable provisions of ERISA, the Code and all other
applicable laws and the rules and regulations thereunder and the terms of all
applicable collective bargaining agreements, except for any failures to be in
such compliance as have not had and could not reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect.  Except as
disclosed in the Parent Disclosure Letter, there are no pending or, to the
knowledge of Parent, threatened or anticipated claims under or with respect to
any Parent Benefit Plan or Parent Employment Arrangement by or on behalf of any
current or former employee, officer or director, or dependent or beneficiary
thereof, or otherwise (other than routine claims for benefits).

          (d)  Except as disclosed in the Parent Disclosure Letter, (i) no
current or former employee, officer or director of Parent or any Parent
Subsidiary will be entitled to any additional rights or benefits or any
acceleration of the time of payment or vesting of any benefits under any Parent
Benefit Plan or Parent Employment Arrangement, and no trustee under any "rabbi
trust", or similar arrangement maintained in connection with any Parent Benefit
Plan or Parent Employment Arrangement will be entitled to any payment, as a
result (either alone or upon the occurrence of any additional or further acts or
events) of the execution of this Agreement or the consummation, announcement or
other actions relating to the Transactions and (ii) no amount
<PAGE>

                                                                              44

payable to any current or former employee, officer or director of Parent or any
Parent Subsidiary will fail to be deductible by reason of Section 280G of the
Code.

          (e)  Each Parent Benefit Plan intended to be a Qualified Plan has
received a favorable determination letter from the Internal Revenue Service that
it is so qualified and nothing has occurred since the date of such letter that
could reasonably be expected to affect the qualified status of such Parent
Benefit Plan.

          (f)  The aggregate accumulated benefit obligations of each Parent
Benefit Plan subject to Title IV of ERISA (as of the date of the most recent
actuarial valuation prepared for such Parent Benefit Plan) do not exceed the
fair market value of the assets of such plan (as of the date of such valuation).

          (g)  All contributions and other payments required to have been made
for any completed historical period by Parent or any Parent Subsidiary to any
Parent Benefit Plan or Parent Employment Arrangement (or to any person pursuant
to the terms thereof) have been timely made or paid in full, or, to the extent
not required to be made or paid for such period, have been reflected in the
consolidated financial statements of Parent.

          (h)  Except as disclosed in the Parent Disclosure Letter, no Parent
Benefit Plan is a multiemployer plan within the meaning of Section 4001(a)(3) of
ERISA, and none of Parent or any Parent Subsidiary has, at any time during the
last six years, contributed to or been obligated to contribute to any such
multiemployer plan.  For purposes of the representations and warranties made in
the last sentence of Section 4.11(c) and in Sections 4.11 (e) and (f), the term
"Parent Benefit Plan" shall be deemed to exclude any such multiemployer plan.

          SECTION 4.12.  Litigation.  Except as disclosed in the Filed Parent
SEC Documents or in the Parent Disclosure Letter, there is no suit, action or
proceeding pending or, to the knowledge of Parent, threatened against Parent or
any Parent Subsidiary that, individually or in the aggregate, has had or could
reasonably be expected to have a Parent Material Adverse Effect, nor is there
any Judgment outstanding against Parent or any Parent Subsidiary that has had or
could reasonably be expected to have a Parent Material Adverse Effect.

          SECTION 4.13.  Compliance with Applicable Laws; Permits.  (a)  Except

in compliance with the terms of all applicable Parent Permits (as defined in
Section 4.13(b)) and all Applicable Laws, except for instances of noncompliance
that, individually and in the aggregate, have not had and could not reasonably
be expected to have a Parent Material Adverse Effect. This Section 4.13 does not
relate to matters with respect to Taxes, which are the subject of Section 4.09,
Environmental Laws, which are the subject of Section 4.17, benefits plans, which
are the subject of Section 4.11 and the operation of nuclear power plants which
are the subject of Section 4.19.

          (b)  Except as disclosed in the Filed Parent SEC Documents or in the
Parent Disclosure Letter, Parent and the Parent Subsidiaries own or have
sufficient rights and consents to use under existing franchises, permits,
easements, leases, and license agreements (the "Parent Permits") all properties,
rights and assets necessary for the conduct of their business and operations as
currently conducted, except where the failure to own or have sufficient rights
to such properties, rights and assets, individually or in the aggregate, have
not had and could not reasonably be expected to have a Parent Material Adverse
Effect.  Except as provided in the Pennsylvania Electricity Generation Customer
Choice and Competition Act of 1996 (the "Pennsylvania Competition Act"), to the
knowledge of Parent, no other private corporation can commence electric public
utility operations in any part of the respective territories now served by
Parent or any Parent Subsidiary, without obtaining a certificate of public
convenience and necessity from the applicable state utility commission.

          SECTION 4.14.  Brokers; Schedule of Fees and Expenses.  No broker,
investment banker, financial advisor or other person, other than Salomon Smith
Barney Inc. and Morgan Stanley & Company Incorporated, the fees and expenses of
which will be paid by Parent, is entitled to any broker's, finder's, financial
advisor's or other similar fee or commission in connection with the Merger and
the other Transactions based upon arrangements made by or on behalf of Parent or
Newco.

          SECTION 4.15.  Opinions of Financial Advisors. Parent has received the
opinions of Salomon Smith Barney Inc. and Morgan Stanley & Company Incorporated,
dated as of January 7, 2000, to the effect that, as of such date, the Exchange
Consideration is fair to the holders of Parent Common Stock from a financial
point of view, signed copies of which opinions have been delivered to the
Company.

          SECTION 4.16.  Year 2000.  The Parent SEC Documents fairly summarize

individually or in the aggregate, a Parent Material Adverse Effect.

          (c)  Environmental Claims.  Except as set forth in the Filed Parent
SEC Documents or in the Parent Disclosure Letter, there are no Environmental
Claims that have had or could reasonably be expected to have, individually or in
the aggregate, a Parent Material Adverse Effect, pending or, to the knowledge of
Parent, threatened against Parent or any of the Parent Subsidiaries.

          (d)  Releases.  Except as set forth in the Filed Parent SEC Documents
or in the Parent Disclosure Letter, there have been no Releases of any Hazardous
Materials that could be reasonably likely to form the basis of any Environ

the extent the following, individually or in the aggregate, have not had and
could not reasonably be expected to have a Parent Material Adverse Effect, (A)

consummation of the Merger and do not violate any other covenant in this

Company will immediately cease all existing activities, discussions and
negotiations with any parties conducted heretofore with respect to any of the

Competing Transaction (including the specific terms thereof), and promptly
furnish to Parent a copy of any such proposal or inquiry in addition to any
information provided to or by any third party relating thereto and if such
proposal or inquiry is not in writing, the identity of the person making such
proposal or inquiry.  Notwithstanding the foregoing, prior to receipt of the
Company Shareholder Approval, the Company may, but only to the extent that the
Board of Directors of the Company shall conclude in good faith, based upon the
advice of its outside counsel, that failure to take such action could reasonably
be expected to constitute a breach of the fiduciary obligations of such Board of
Directors under Applicable Law, in response to a proposal for a Company
Competing Transaction that constitutes a Qualifying Company Proposal (as defined
in Section 5.02(d)) that did not result from the breach or a deemed breach of
this Section 5.02, and subject to compliance with the notification provisions of
this Section 5.02, (A) furnish non-public information with respect to the
Company to the person proposing such Company Competing Transaction and its
Representatives pursuant to a confidentiality agreement with terms no less
restrictive of such person than those set forth in the Confidentiality Agreement
(as defined in Section 6.02) and (B) participate in discussions or negotiations
with such person and its Representatives regarding such Company Competing
Transaction.  Without limiting the foregoing, it is agreed that any violation of
the restrictions set forth in this Section 5.02(a) by any Representative or
affiliate of the Company or any Company Subsidiary, whether or not such person
is purporting to act on behalf of the Company or any Company Subsidiary or
otherwise, shall be deemed to be a breach of this Section 5.02(a) by the
Company.

          (b)  Neither the Board of Directors of the Company nor any committee
thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a
manner adverse to Parent, the approval or recommendation by the Board of
Directors of the Company of this Agreement and the Transactions, (ii) approve,
or permit or cause the Company to enter into, any definitive agreement providing
for the implementation of any Company Competing Transaction (each a "Company
Acquisition Agreement") or (iii) approve or recommend, or propose to approve or
recommend, any Company Competing Transaction.  Notwithstanding the foregoing,
prior to receipt of the Company Shareholder Approval, and only to the extent
that the Board of Directors of the Company shall conclude in good faith, based
upon the advice of its outside counsel, that failure to take such action could
reasonably be expected to constitute a breach of the fiduciary obligations of
such Board of Directors under Applicable Law in response to a proposal for a
Company Competing Transaction that constitutes a Qualifying Company Proposal
that did not result from the breach or a deemed breach of this Section 5.02, (A)
the Board of Directors of the Company may withdraw or modify its approval or
recommendation of this Agreement and the Transactions and, in connection
therewith, approve or recommend such Qualifying Company Proposal and (B) the
Board of Directors of the Company may approve and the Company may enter into a
Company Acquisition Agreement contemporaneously with its termination of this
Agreement pursuant to Section 8.01(f).

          (c)  Nothing contained in this Section 5.02 shall prohibit the Company
from taking and disclosing to its shareholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act or from making any disclosure to its
shareholders if, in the good faith judgment of the Board of Directors of the
Company after consultation with outside counsel, failure to so disclose would be
inconsistent with its obligations under Applicable Law.

          (d)  For purposes of this Agreement, "Qualifying Company Proposal"
means any proposal made by a third party to acquire all of the equity securities
or all or substantially all of the assets of the Company, pursuant to a tender
offer, a merger, a consolidation, a recapitalization, a sale of its assets or
otherwise, that is (A) for consideration that is comprised solely of cash or
marketable securities, or a combination thereof, and not conditioned on
financing, (B) on terms which the Board of Directors of the Company determines
in its good faith judgment (based on the advice of a nationally recognized
independent investment banking firm) to be superior from a

financial point of view to the holders of Company Common Stock to the
Transactions (taking into account all of the terms of any proposal by Parent to
amend or modify the terms of the Transactions) and to be more favorable
generally to the Company's shareholders than the Transactions (taking into
account all financial and strategic considerations, including relevant legal,
financial, regulatory and other aspects of such proposal and the third party
making such proposal and the conditions and prospects for completion of such
proposal, the strategic direction of and benefits sought by the Company and all
of the terms of any proposal by Parent to amend or modify the terms of the
Transactions) and (C) reasonably capable of being completed within 18 months of
the termination of this Agreement or by the Outside Date, whichever is later,
taking into account all legal, financial, regulatory and other aspects of such
proposal and the third party making such proposal.

          SECTION 5.03.  No Solicitation by Parent. (a)  Parent agrees that,
during the term of this Agreement, it shall not, and shall not authorize or
permit any of its subsidiaries or any of its or its subsidiaries'
Representatives, directly or indirectly, to (i) solicit, initiate, encourage or
facilitate, or furnish or disclose non-public information in furtherance of, any
inquiries or the making of any proposal with respect to a Parent Competing
Transaction (as defined herein) or (ii) negotiate, explore or otherwise engage
in discussions with any person (other than Company or Newco or their respective
Representatives) with respect to any Parent Competing Transaction.  The term
"Parent Competing Transaction" means any recapitalization, merger, consolidation
or other business combination involving Parent, or acquisition of any material
portion of the capital stock or assets (except for (A) acquisitions of assets in
the ordinary course of business, (B) acquisitions by Parent that do not and
could not reasonably be expected to impede the consummation of the Merger and do
not violate any other covenant in this Agreement, (C) transactions disclosed in
the Parent Disclosure Letter and (D) the Transactions) of Parent, or any
combination of the foregoing.  Parent will immediately cease all existing
activities, discussions and negotiations with any parties conducted heretofore
with respect to any of the foregoing and shall use its reasonable best efforts
to enforce any confidentiality or similar agreement relating to a Parent
Competing Transaction.  From and after the execution of this Agreement, Parent
shall immediately advise the Company in writing of the receipt, directly or
indirectly, of any inquiries, discussions, negotiations, or proposals relating
to a Parent Competing Transaction (including the specific terms thereof), and
promptly furnish

                                                                              65

to the Company a copy of any such proposal or inquiry in addition to any
information provided to or by any third party relating thereto and if such
proposal or inquiry is not in writing, the identity of the person making such
proposal or inquiry. Notwithstanding the foregoing, prior to receipt of the
Parent Shareholder Approval, Parent may, but only to the extent that the Board
of Directors of Parent shall conclude in good faith, based upon the advice of
its outside counsel, that failure to take such action could reasonably be
expected to constitute a breach of the fiduciary obligations of such Board of
Directors under Applicable Law, in response to a proposal for a Parent Competing
Transaction that constitutes a Qualifying Parent Proposal (as defined in Section
5.03(d)) that did not result from the breach or a deemed breach of this Section
5.03, and subject to compliance with the notification provisions of this Section
5.03, (A) furnish non-public information with respect to Parent to the person
proposing such Parent Competing Transaction and its Representatives pursuant to
a confidentiality agreement with terms no less restrictive of such person than
those set forth in the Confidentiality Agreement (as defined in Section 6.02)
and (B) participate in discussions or negotiations with such person and its
Representatives regarding such Parent Competing Transaction. Without limiting
the foregoing, it is agreed that any violation of the restrictions set forth in
this Section 5.03(a) by any Representative or affiliate of Parent or any Parent
Subsidiary, whether or not such person is purporting to act on behalf of Parent
or any Parent Subsidiary or otherwise, shall be deemed to be a breach of this
Section 5.03(a) by Parent.

          (b)  Neither the Board of Directors of Parent nor any committee
thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a
manner adverse to the Company, the approval or recommendation by the Board of
Directors of Parent of this Agreement and the Transactions, (ii) approve, or
permit or cause Parent to enter into, any definitive agreement providing for the
implementation of any Parent Competing Transaction (each a "Parent Acquisition
Agreement") or (iii) approve or recommend, or propose to approve or recommend,
any Parent Competing Transaction. Notwithstanding the foregoing, prior to
receipt of the Parent Shareholder Approval, and only to the extent that the
Board of Directors of Parent shall conclude in good faith, based upon the advice
of its outside counsel, that failure to take such action could reasonably be
expected to constitute a breach of the fiduciary obligations of such Board of
Directors under Applicable Law in response to a proposal for a Parent Competing
Transaction that constitutes a Qualifying Parent Proposal that did not result
from the

breach or a deemed breach of this Section 5.03, (A) the Board of Directors of
Parent may withdraw or modify its approval or recommendation of this Agreement
and the Transactions and, in connection therewith, approve or recommend such
Qualifying Parent Proposal and (B) the Board of Directors of Parent may approve
and Parent may enter into a Parent Acquisition Agreement contemporaneously with
its termination of this Agreement pursuant to Section 8.01(h).

          (c)  Nothing contained in this Section 5.03 shall prohibit Parent from
taking and disclosing to its shareholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act or from making any disclosure to its
shareholders if, in the good faith judgment of the Board of Directors of Parent
after consultation with outside counsel, failure to so disclose would be
inconsistent with its obligations under Applicable Law.

          (d)  For purposes of this Agreement, "Qualifying Parent Proposal"
means any proposal made by a third party to acquire all of the equity securities
or all or substantially all of the assets of Parent, pursuant to a tender offer,
a merger, a consolidation, a recapitalization, a sale of its assets of
otherwise, that is (A) for consideration that is comprised solely of cash or
marketable securities, or a combination thereof, and not conditioned on
financing, (B) on terms which the Board of Directors of Parent determines in its
good faith judgment (based on the advice of a nationally recognized independent
investment banking firm) to be superior from a financial point of view to the
holders of Parent Common Stock to the Transactions (taking into account all of
the terms of any proposal by Company to amend or modify the terms of the
Transactions) and to be more favorable generally to Parent's shareholders than
the Transactions (taking into account all financial and strategic
considerations, including relevant legal, financial, regulatory and other
aspects of such proposal and the third party making such proposal and the
conditions and prospects for completion of such proposal, the strategic
direction of and benefits sought by Parent and all of the terms of any proposal
by the Company to amend or modify the terms of the Transactions) and (C)
reasonably capable of being completed within 18 months of the termination of
this Agreement or by the Outside Date, whichever is later, taking into account
all legal, financial, regulatory and other aspects of such proposal and the

Section 6.01(d) shall not be affected by the commencement, public proposal,
public disclosure or communication to the Company of any Company Competing
Transaction.

          (e)  Parent shall, as soon as practicable following the date of this

          SECTION 6.02.  Access to Information; Confidentiality.  Each of the
Company and Parent after reasonable notice shall, and shall cause each of its
respective subsidiaries to, afford to the other party and to the officers,
employees, accountants, counsel, financial advisors and other representatives of

pursuant to this Section 6.02 shall be subject to the confidentiality agreement
dated July 15, 1999, between the Company and Parent (the "Confidentiality

          SECTION 6.03.  Regulatory Matters; Reasonable Best Efforts.  (a)
Regulatory Approvals.  Upon the terms and subject to the conditions set forth in
this Agreement, and subject to actions taken in compliance with Section 5.02(b)

promptly prepare and file all necessary documentation, to effect all necessary
applications, notices, petitions, filings and other documents, and shall use
reasonable best efforts to obtain all necessary Consents of all Governmental
Entities necessary or advisable to consummate and make effective, in the most
expeditious manner practicable, the Merger and the other Transactions, including
the Parent Required Statutory Approvals and the Company Required Statutory

fully carry out the purposes of this Agreement. Notwithstanding the foregoing,
the Company and its Representatives and Parent and its Representatives shall not

with Section 5.02(b) or 5.03(b), respectively.

          (c)  State Anti-Takeover Statutes.  In connection with and without
limiting the generality of Section 6.03(b), Parent and the Company shall (i)
take all action necessary to ensure that no state anti-takeover statute or
similar statute or regulation is or becomes applicable to any Transaction or
this Agreement and (ii) if any state anti-takeover statute or similar statute or
regulation becomes applicable to any Transaction or this Agreement, take all
action necessary to ensure that the Merger and the other Transactions may be

Agreement and otherwise to minimize the effect of such statute or regulation on
the Merger and the other Transactions.  Notwithstanding the foregoing, the
Company and its Representatives and Parent and its Representatives shall not be

          (d)  Notices.  The Company shall give prompt notice to Parent, and
Parent or Newco shall give prompt notice to the Company, of (i) any
representation or warranty made by it contained in this Agreement that is

inaccurate in any material respect or (ii) the failure by it to comply with or
satisfy in any material respect any covenant, condition or agreement to be
complied with or satisfied by it under this Agreement; provided, however, that
no such notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.

          SECTION 6.04.  Company and Parent Stock Options and Other Stock Plans.
(a)  Prior to the Merger Effective Time, the Company Board (or, if appropriate,
any committee administering the Company Stock Plans) shall adopt such
resolutions or take such other actions as may be required to effect the
following:

          (i)  adjust the terms of all outstanding Company Employee Stock
     Options to provide that, at the Merger Effective Time, each Company
     Employee Stock Option out standing immediately prior to the Merger
     Effective Time
<PAGE>

                                                                              72

     shall be deemed to constitute an option to acquire, on the same terms and
     conditions as were applicable under such Company Employee Stock Option, the
     same number of shares of Newco Common Stock as the holder of such Company
     Employee Stock Option would have been entitled to receive pursuant to the
     Merger had such holder exercised such Company Employee Stock Option in full
     immediately prior to the Merger Effective Time, at a price per share equal
     to (A) the aggregate exercise price for the shares of Company Common Stock
     otherwise purchasable pursuant to such Company Employee Stock Option
     immediately prior to the Merger Effective Time (whether or not exercisable)
     divided by (B) the number of shares of Newco Common Stock deemed
     purchasable pursuant to such Company Employee Stock Option; provided,
     however, that in the case of any qualified stock options under Sections
     422-424 of the Code, the option price, the number of shares purchasable
     pursuant to such option and the terms and conditions of exercise of such
     option shall be determined in order to comply with Section 424(a) of the
     Code; provided, further, however, that solely for purposes of making the
     adjustments to Company Employee Stock Options required by this Section
     6.04, the Company Conversion Number shall be 0.95 and the Company Cash
     Consideration shall be disregarded;

          (ii)   make such other changes to the Company Stock Plans and the
     terms of any Company Employee Stock Options as it deems appropriate to give
     effect to the Merger (subject to the approval of Parent, which shall not be
     unreasonably withheld); and

          (iii)  ensure that, after the Merger Effective Time, no Company
     Employee Stock Options may be granted under any Company Stock Plan.

          (b)    Prior to the Exchange Effective Time, the Parent Board (or, if
appropriate, any committee administering the Parent Stock Plans) shall adopt
such resolutions or take such other actions as may be required to effect the
following:

          (i)    adjust the terms of all outstanding Parent Employee Stock
     Options to provide that, at the Exchange Effective Time, each Parent
     Employee Stock Option out standing immediately prior to the Exchange
     Effective Time shall be deemed to constitute an option to acquire, on the
     same terms and conditions as were applicable under such Parent Employee
     Stock Option, the same number of shares of Newco Common Stock as the
<PAGE>

                                                                              73

     holder of such Parent Employee Stock Option would have been entitled to
     receive pursuant to the Merger had such holder exercised such Parent
     Employee Stock Option in full immediately prior to the Exchange Effective
     Time, at a price per share equal to (A) the aggregate exercise price for
     the shares of Parent Common Stock otherwise purchasable pursuant to such
     Parent Employee Stock Option immediately prior to the Exchange Effective
     Time (whether or not exercisable) divided by (B) the number of shares of
     Newco Common Stock deemed purchasable pursuant to such Parent Employee
     Stock Option; provided, however, that in the case of any qualified stock
     stock options under Sections 422-424 of the Code, the option price, the
     number of shares purchasable pursuant to such option and the terms and
     conditions of exercise of such option shall be determined in order to
     comply with Section 424(a) of the Code;

          (ii)   make such other changes to the Parent Stock Plans and the terms
     of outstanding Parent Employee Stock Options as it deems appropriate to
     give effect to the Merger (subject to the approval of the Company, which
     shall not be unreasonably withheld); and

          (iii)  ensure that, after the Exchange Effective Time, no Parent
     Employee Stock Options may be granted under any Parent Stock Plan.

            (c)  At the Merger Effective Time, and subject to compliance by the
Company with Section 6.04(a), Newco shall assume all the obligations of the
Company under the Company Stock Plans, each outstanding Company Employee Stock
Option and the agreements evidencing the grants thereof.  As soon as practicable
after the Merger Effective Time, Newco shall deliver to the holders of Company
Employee Stock Options appropriate notices setting forth such holders' rights
pursuant to the respective Company Stock Plans, and the agreements evidencing
the grants of such Company Employee Stock Options shall continue in effect on
the same terms and conditions (subject to the adjustments required by this
Section 6.04 after giving effect to the Merger).  Newco shall comply with the
terms of the Company Stock Plans and ensure, to the extent required by, and
subject to the provisions of, such Company Stock Plans, that the Company
Employee Stock Options that qualified as qualified stock options prior to the
Merger Effective Time continue to qualify as qualified stock options after the
Merger Effective Time.

                                                                              74

          (d)  At the Exchange Effective Time, and subject to compliance by
Parent with Section 6.04(b), Newco shall assume all the obligations of Parent
under the Parent Stock Plans, each outstanding Parent Employee Stock Option and
Parent SAR the agreements evidencing the grants thereof.  As soon as practicable
after the Exchange Effective Time, Newco shall deliver to the holders of Parent
Employee Stock Options and Parent SARs appropriate notices setting forth such
holders' rights pursuant to the respective Parent Stock Plans, and the
agreements evidencing the grants of such Parent Employee Stock Options and
Parent SARs shall continue in effect on the same terms and conditions (subject
to the adjustments required by this Section 6.04 after giving effect to the
Merger).  Newco shall comply with the terms of the Parent Stock Plans and
ensure, to the extent required by, and subject to the provisions of, such Parent
Stock Plans, that the Parent Employee Stock Options that qualified as qualified
stock options prior to the Exchange Effective Time continue to qualify as
qualified stock options after the Exchange Effective Time.

          (e)  With respect to each employee or director benefit or compensation
plan, program or arrangement, other than the Company Stock Plans and the Parent
Stock Plans, under which Company Common Stock or Parent Common Stock is required
to be used for purposes of the payment of benefits, grant of awards or exercise
of options (each, a "Stock Plan"), (i) the Company and the Parent shall take
such action as may be necessary so that, after the Merger Effective Time, such
Stock Plan shall provide for issuance or purchase in the open market only of
Newco Common Stock rather than Company Common Stock or Parent Common Stock, as
the case may be, and otherwise to amend such Stock Plans to reflect this
Agreement and the Merger, and (ii) Newco shall take all corporate action
necessary or appropriate to obtain shareholder approval with respect to such
Stock Plan to the extent such approval is required for purposes of the Code or
other Applicable Law.  Newco shall take all corporate action necessary to
reserve for issuance a sufficient number of shares of Newco Common Stock for
delivery upon exercise of the Company Employee Stock Options and Parent Employee
Stock Options assumed in accordance with this Section 6.04 or the payment of
benefits, grant of awards or exercise of options under such Stock Plans.  As

accordance with their respective terms (as in effect on the date of this
Agreement or as amended in accordance with or as permitted by this Agreement),
all the collective bargaining agreements of the Company, Parent or any of their
respective subsidiaries disclosed in the Company Disclosure Letter or the Parent
Disclosure Letter, respectively; provided, however, that this Section 6.05(a) is
not intended to

                                                                              76

prevent Newco from enforcing such agreements in accordance with their respective
terms, including enforcement of any reserved right to amend, modify, suspend,
revoke or terminate any such agreement.

          (b)  Subject to Applicable Law and obligations under applicable
collective bargaining agreements, it is the current intention of Parent and the
Company that any reductions in workforce following the Merger Effective Time in
respect of employees of Newco and its subsidiaries shall be made on a fair and
equitable basis, in light of the circumstances and the objectives to be
achieved, as determined by Newco, without regard to whether employment was with
the Company or the Company Subsidiaries or Parent or the Parent Subsidiaries and
with due consideration to the applicable employee's previous work history, prior
experience and skills and Newco's business needs, and any employee whose
employment is terminated or job is eliminated shall be entitled to participate
on a fair and equitable basis as determined by Newco in the job opportunity and
employment placement programs offered by Newco or any of its subsidiaries.

          (c)  Subject to Applicable Law and obligations under applicable
collective bargaining agreements, each Company Benefit Plan, Parent Benefit
Plan, Company Employment Arrangement and Parent Employment Arrangement in effect
on the date of this Agreement (or as amended or established in accordance with
or as permitted by this Agreement) shall be maintained in effect by Newco and
its subsidiaries, except as provided in Section 6.04, with respect to their
current and former employees, officers or directors of the Company and Company
Subsidiaries and Parent and Parent Subsidiaries, respectively, who are covered
by such plans or arrangements immediately prior to the Merger Effective Time
until Newco determines otherwise on or after the Merger Effective Time.  Newco
and its subsidiaries shall honor, perform and, with respect to each Company
Benefit Plan and Parent Benefit Plan and Company Employment Arrangement and
Parent Employment Arrangement that is not a multiemployer benefit plan within
the meaning of Section 4001(a)(3) of ERISA, sponsor and administer, each such
Company Benefit Plan and Parent Benefit Plan and Company Employment Arrangement

Parent Benefit Plan and Parent Employment Arrangement maintained by Parent
immediately prior to the Exchange Effective Time and (ii) perform the
obligations under, sponsor and administer such plan or arrangement in the same
manner and to the same extent that the Company or Parent, as the case may be,
would be required to perform, sponsor and administer thereunder; provided,
however, that nothing contained herein shall limit any reserved right contained
in any such Company Benefit Plan, Company Employment Arrangement, Parent Benefit
Plan or Parent Employment Arrangement to amend, modify, suspend, revoke or
terminate any such plan or arrangement. Without limiting the foregoing, (i) each
participant in any Company Benefit Plan or Parent Benefit Plan shall receive
credit for purposes of eligibility to participate, vesting and eligibility to
receive benefits (but specifically excluding for benefit accrual purposes or
where such crediting would result in a duplication of benefits) under any
benefit plan of Newco or any of its subsidiaries or affiliates for service
credited for the corresponding purpose under any such benefit plan; provided,
however, that such crediting of service shall not operate to cause any such plan
or arrangement to fail to comply with the applicable provisions of the Code or
ERISA, (ii) each benefit plan of Newco or its subsidiaries which is a medical,
dental or health benefit plan shall take into account for purposes of
determining a participant's deductibles and out-of-pocket limits thereunder
expenses previously incurred by the participant during the same year while
participating in any other such Company Benefit Plan or Parent Benefit Plan and
shall waive any restrictions and limitations for pre-existing conditions
provided therein for any participant to the extent not applicable to the
participant in any other such Company Benefit Plan or Parent Benefit Plan in
which the participant participated immediately prior to participating in that
benefit plan, and (iii) each benefit plan of Newco or its subsidiaries which is
a cafeteria plan under Section 125 of the Code shall cause credits and debits in
respect of any participant in any flexible spending account thereunder for a
plan year to be transferred to and maintained in any such corresponding Company
Benefit Plan or Parent Benefit Plan in which such participant may subsequently
participate during the same year. The Company and the Parent will cooperate on
and after the date hereof to develop appropriate employee benefit plans,
programs and arrangements, including but not limited to, executive and incentive
compensation, stock option and supplemental executive retirement plans for
employees and directors of Newco and its subsidiaries from and after the Merger
Effective Time. However, no provision contained in this Section 6.05(c) shall be
deemed to constitute an employment contract between Newco and any
<PAGE>

                                                                              78

individual, or a waiver of Newco's right to discharge any employee at any time,
with or without cause.

          SECTION 6.06.  Indemnification.  (a)  Newco shall, to the fullest
extent permitted by Applicable Law, honor all the Company's and Parent's
respective obligations to indemnify (including any obligations to advance funds
for expenses) the current and former directors and officers of the Company or
Parent, as the case may be, for acts or omissions by such directors and officers
occurring prior to the Merger Effective Time to the extent that such obligations
to indemnify exist on the date of this Agreement, whether pursuant to the
Company Charter or the Parent Charter, as the case may be, the Company By-laws
or the Parent By-laws, as the case may be, individual indemnity agreements or
otherwise, and such obligations shall survive the Merger and shall continue in
full force and effect in accordance with the terms of the Company Charter or the
Parent Charter, as the case may be, the Company By-laws or the Parent By-laws,
as the case may be, and such individual indemnity agreements from the Merger
Effective Time.

          (b)  For a period of six years after the Merger Effective Time, Newco
shall cause to be maintained in effect the current policies of directors' and
officers' liability insurance maintained by the Company or Parent or such
substantially comparable policies as in effect on the Closing Date, as the case
may be, (provided that Newco may substitute therefor policies with reputable and
financially sound carriers of at least the same coverage and amounts containing
terms and conditions which are no less advantageous) with respect to claims
arising from or related to facts or events which occurred at or before the
Merger Effective Time.  If such insurance coverage cannot be obtained at all,
Newco shall maintain the most advantageous policies of directors' and officers'
insurance reasonably obtainable.

          (c)  From and after the Merger Effective Time, to the fullest extent
permitted by Applicable Law, Newco shall indemnify, defend and hold harmless the
present and former officers and directors of the Company and Parent, as the case
may be, and their respective subsidiaries and any of their respective employees
who act as a fiduciary under any Company Benefit Plan (each an "Indemnified
Party") against all losses, claims, damages, liabilities, fees and expenses
(including attorneys' fees and disbursements), judgments, fines and amounts paid
in settlement (in the case of settlements, with the approval of the indemnifying
party (which approval shall not be unreasonably withheld)) (collectively,
"Losses"), as incurred (payable monthly upon

respect of, any actual or threatened action, suit, proceeding or investigation,

with filing, printing and mailing the Proxy Statement and the Form S-4 shall be
shared equally by Parent and the Company.

to clause (iii) above such payment shall be made on the date of execution of
such definitive agreement or, if earlier, consummation of such transaction or
another transaction with the same party or its affiliates).

          (c)  Parent shall pay to the Company a fee of $250,000,000 if:  (i)

          SECTION 6.10.  Affiliates.  (a)  Promptly following the date of
     execution of this Agreement, the Company shall deliver to Parent and Newco
     a letter identifying all persons who are expected by the Company to be on

          SECTION 6.11.  Stock Exchange Listing.  Parent and the Company shall

     issuance, prior to the Closing Date.

          SECTION 6.12.  Rights Agreements; Consequences if Rights Triggered.

                                                                              82

     Exchange Ratio and the Parent Exchange Ratio as the Company and Parent
     shall mutually agree so as to preserve the economic benefits that the
     Company and Parent each reasonably expected on the date of this Agreement
     to receive as a result of the consummation of the Merger and the other
     Transactions.

          SECTION 6.13.  Tax Treatment.  The parties intend (a) the Merger to
     constitute transactions described in Section 351 of the Code and (b) the
     Second Step Merger to constitute a transaction described in Section 368(a)
     of the Code. Each party and its affiliates shall use reasonable efforts to
     cause the Merger to so qualify and to obtain (i) the opinion of Cravath,
     Swaine & Moore to the effect that (A) the Merger will constitute
     transactions described in Section 351 of the Code and (B) the Second Step
     Merger will constitute a transaction described in Section 368(a) of the
     Code and (ii) the opinion of Jones, Day, Reavis & Pogue to the effect that
     the Second Step Merger will constitute a transaction described in Section
     368(a) of the Code. For purposes of the tax opinions described in Sections
     7.02(d) and 7.03(d) of this Agreement, each of Parent, Newco and the
     Company shall provide customary representation letters substantially in the
     form of Exhibits E, F and G, respectively, each dated on or about the date
     that is two business days prior to the date the Proxy Statement is mailed
     to the shareholders of Parent and the Company and reissued as of the
     Closing Date. Each of Parent, Newco and the Company and each of their
     respective affiliates shall not take any action and shall not fail to take
     any action or suffer to exist any condition which action or failure to act
     or condition would prevent, or would be reasonably likely to prevent, (i)
     the Merger from constituting transactions described in Section 351 of the
     Code or (ii) the Second Step Merger from constituting a transaction
     described in Section 368(a) of the Code.

          SECTION 6.14.  Reorganization and Amendment.  The parties to this
     Agreement acknowledge and agree that in the event Parent implements the
     Parent Reorganization prior to the Exchange Effective Time, certain changes
     to the structure of the Merger and the other Transactions will be necessary
     in order for the Merger and the other Transactions to be consummated as
     contemplated hereby and for Newco and its subsidiaries to have, following
     the Merger Effective Time, the corporate structure as contemplated hereby,
     and the parties to this Agreement agree to negotiate in good faith and
     enter into an amendment to this Agreement to implement such necessary
     changes.

          SECTION 6.15.  Common Stock Repurchases.  (a)  Subject to the last two
     sentences of this Section 6.15(a), the Company shall use commercially
     reasonable best efforts to purchase prior to the Closing at prevailing
     market prices to the extent possible shares of Company Common Stock for an
     aggregate consideration of $1,000,000,000, and Parent shall use
     commercially reasonable best efforts to purchase prior to the Closing at
     prevailing market prices to the extent possible shares of Parent Common
     Stock for an aggregate consideration of $500,000,000, which purchases
     shall, in each case, be in addition to all other purchases permitted by
     this Agreement (other than Section 6.15(b)) or contemplated in the Company
     Disclosure Letter or the Parent Disclosure Letter. The Company and Parent
     shall consult on a regular basis concerning the purchases described in the
     preceding sentence and cooperate in connection therewith. Neither the
     Company nor Parent shall purchase shares pursuant to this Section 6.15(a)
     if it is reasonably likely that such purchases would result in the failure
     of the closing conditions set forth in Sections 7.02(d) and 7.03(d) or the
     failure of the Merger and the other Transactions to be treated as a
     purchase of the Company by Parent under GAAP.

          (b) Prior to the Merger Effective Time, the Company shall purchase, at
     prevailing market prices to the extent possible, the minimum number of
     shares of Company Common Stock necessary in order that, after giving effect
     to the repurchases contemplated by Section 6.15(a), the Merger and the
     other Transactions are treated as a purchase of the Company by Parent under
     GAAP.

          (c) To the extent the purchases contemplated by this Section 6.15 are
     inconsistent with any other provision of this Agreement, the Company
     Disclosure Letter or the Parent Disclosure Letter, such provision shall be
     deemed to be amended to permit such purchases.

          SECTION 6.16.  Parity of Compensation.  At any time during the period
     from the Merger Effective Time until December 31, 2003 (the "Transition
     Period") when the Chairman of the Board of Directors, Chief Executive
     Officer and President of Parent as of the date of this Agreement (the
     "Parent Chairman") and the Chairman of the Board of Directors, Chief
     Executive Officer and President of the Company (the "Company Chairman") as
     of the date of this Agreement are Co-Chief Executive Officers of Newco,
     each such Co-Chief Executive Officer shall receive the same salary, bonus
     and other compensation (including option grants and other incentive awards
     and all other forms of compensation) and enjoy the same other benefits and
     the same

                                                                              84

     employment security arrangements as the other Co-Chief Executive Officer.

          SECTION 6.17.  Board Seats.  The Parent Chairman will retire as an
     executive of Newco at the end of the Transition Period and shall no longer
     serve as chairman of the executive committee of the Newco Board, but shall
     continue as a member of the Newco Board. The Company Chairman shall become
     the sole Chief Executive Officer of Newco immediately prior to the end of
     the Transition Period, and at such time shall be the Chairman of the Board
     of Directors of Newco, if immediately prior to such time he holds the
     position of Co-Chief Executive Officer. The Newco Board or the nominating
     committee thereof, as applicable, shall nominate for election the Parent
     Chairman and the Company Chairman as part of management's slate of
     candidates at each meeting of the shareholders (if at the time of such
     meeting the Parent Chairman or the Company Chairman, as applicable, is a
     member of the Newco Board) at which members of the Newco Board shall be
     elected as shall be necessary in order that the Parent Chairman or the
     Company Chairman, as applicable, serve as a director of Newco from the end
     of the Transition Period until the election of directors first following
     December 31, 2005.

     Merger and the Transactions at or prior to the Merger Effective Time, such
     approvals shall have become Final Orders (as defined below) and such Final
     Orders shall not impose terms or conditions which, individually or in the
     aggregate, could reasonably be expected to have a Material Adverse Effect
     on Newco and its prospective subsidiaries taken as a whole or which would
     be materially inconsistent with the agreements of the parties contained
     herein. A "Final Order" means action by the relevant Governmental Entity
     which has not been reversed, stayed, enjoined, set aside, annulled or

     prior to asserting this condition, subject to Section 6.03, each of the
     parties shall have used all reasonable efforts to prevent the entry of any
     such injunction or other order and to appeal as promptly as possible any
     such injunction or other order  that may be entered.

     obligations of Parent and Newco to effect the Merger are further subject to
     the following conditions:

          (a)  Representations and Warranties.  The representations and
     warranties of the Company in this Agreement shall be true and correct as of
     the date of this Agreement and as of the Closing Date as though made on the
     Closing Date, except to the extent such representations and warranties
     expressly relate to an earlier date (in which case such representations and
     warranties shall be true and correct on and as of such earlier date), other
     than for such failures to be true and correct that, individually and in the
     aggregate, have not had and could not reasonably be expected to have a
     Company Material Adverse Effect. Parent shall have received a certificate
     signed on behalf of the Company by the chief executive officer or the chief
     financial officer of the Company to such effect. For purposes of
     determining the satisfaction of this condition, the representations and
     warranties of the Company shall be deemed not qualified by any references
     therein to materiality generally or to whether or not any breach results or
     may result in a Company Material Adverse Effect.

          (b)  Performance of Obligations of the Company.  The Company shall
     have performed in all material respects all obligations required to be
     performed by it under this Agreement at or prior to the Closing Date, and
     Parent shall have received a certificate signed on behalf of the Company by
     the chief executive officer and the chief financial officer of the Company
     to such effect.

          (c)  Letters from Company Affiliates.  Parent shall have received from
     each person named in the letter referred to in Section 6.10(a) an executed
     copy of an agreement substantially in the form of Exhibit C.

          (d)  Tax Opinion.  Parent shall have received a written opinion, dated
     as of the Closing Date, from Cravath, Swaine & Moore, counsel to Parent, to
     the effect that (i) the Merger will constitute transactions described in
     Section 351 of the Code and (ii) the Second Step Merger will constitute a
     transaction described in Section 368(a) of the Code; it being understood
     that in rendering such opinion, such tax counsel shall be entitled to rely
     upon customary representations provided by the parties hereto substantially
     in the form of Exhibits E, F and G.

                                                                              87

     the Closing Date, except to the extent such representations and warranties
     expressly relate to an earlier date (in which case such representations and
     warranties shall be true and correct on and as of such earlier date), other
     than for such failures to be true and correct that, individually and in the
     aggregate, have not had and could not reasonably be expected to have a
     Parent Material Adverse Effect. The Company shall have received a
     certificate signed on behalf of Parent by the chief executive officer or
     the chief financial officer of Parent to such effect. For purposes of
     determining the satisfaction of this condition, the representations and
     warranties of Parent and Newco shall be deemed not qualified by any
     references therein to materiality generally or to whether or not any breach
     results or may result in a Parent Material Adverse Effect.

          (b)  Performance of Obligations of Parent and Newco.  Parent and Newco
     shall have performed in all material respects all obligations required to
     be performed by them under this Agreement at or prior to the Closing Date,
     and the Company shall have received a certificate signed on behalf of
     Parent by the chief executive officer and the chief financial officer of
     Parent to such effect.

          (c)  Letters from Parent Affiliates.  The Company shall have received

     in the form of Exhibits E, F and G.

          (e)  First Step Exchange.  The First Step Exchange shall have been
     consummated.

                       Termination, Amendment and Waiver

               SECTION 8.01.  Termination. This Agreement may be terminated at
     any time prior to the Exchange Effective Time, whether before or after
     receipt of the Company Shareholder Approval or the Parent Shareholder
     Approval:

               (a)  by mutual written consent of Parent, Newco and the Company;

               (b)  by either Parent or the Company:

                      (i)   if the Second Step Merger is not consummated on or
               before March 31, 2001 (the "Outside Date"), unless the failure to
               consummate the Merger is the result of a breach of this Agreement
               by the party seeking to terminate this Agreement; provided,
               however, that the passage of such period shall be tolled for any
               part thereof during which any party shall be subject to a
               nonfinal order, decree, ruling or action restraining, enjoining
               or otherwise prohibiting the consummation of the Merger;

                      (ii)  if any Governmental Entity issues an order, decree
               or ruling or takes any other action permanently enjoining,
               restraining or otherwise prohibiting the Merger and such order,
               decree, ruling or other action shall have become final and
               nonappealable;

                      (iii) if any condition to the obligation of such party to
               consummate the Merger set forth in Section 7.02 (in the case of
               Parent) or 7.03 (in the case of the Company) becomes incapable of
               satisfaction prior to the Outside Date; provided, however, that
               the failure of such condition to be met is not the result of a
               material breach of this Agreement by the party seeking to
               terminate this Agreement;

                      (iv)  if, upon a vote at a duly held meeting to obtain the
               Company Shareholder Approval, the Company Shareholder Approval is
               not obtained; or

                      (v)   if, upon a vote at a duly held meeting of Parent to
               obtain the Parent Shareholder Approval, the Parent Shareholder
               Approval is not obtained;

          any material respect any of its representations, warranties or
          covenants contained in this Agreement, which breach or failure to
          perform (i) would give rise to the failure of a condition set forth in
          Section 7.02(a) or 7.02(b), and (ii) cannot be or has not been cured
          within 30 days after the giving of written notice to the Company of
          such breach (provided that Parent is not then in breach of any
          representation, warranty or covenant contained in this Agreement);

               (d)  by Parent, if (i) the Company Board or any committee thereof

          respect;

               (e)  by the Company, if Parent breaches or fails to perform in
          any material respect of any of its representations, warranties or
          covenants contained in this Agreement, which breach or failure to
          perform (i) would give rise to the failure of a condition set forth in
          Section 7.03(a) or 7.03(b), and (ii) cannot be or has not been cured
          within 30 days after the giving of written notice to Parent of such
          breach (provided that the Company is not then in breach of any
          representation, warranty or covenant in this Agreement);

               (f)  by the Company, if prior to receipt of the Company
          Shareholder Approval, (i) the Company has received a proposal for a
          Company Competing Transaction that constitutes a Qualifying Company
          Proposal that was not solicited or encouraged by the Company or its
          Representatives and that did not otherwise result from the breach or a
          deemed breach of Section 5.02, (ii) the Board of Directors of the
          Company has determined in good faith, based upon the advice of its
          outside counsel that failure to take such action could reasonably be

          5.03, (ii) the Board of Directors of Parent has determined in good
          faith, based upon the advice of its outside counsel that failure to

     damages resulting from its wilful breach of this Agreement (including any

                       Form of Company Affiliate Letter


Dear Sirs:

          The undersigned refers to the Amended and Restated Agreement and Plan
of Exchange and Merger (the "Merger Agreement") dated as of September 22, 1999,
as amended and restated as of January 7, 2000, among PECO Energy Company, a
Pennsylvania corporation, Newholdco Corporation, a Pennsylvania corporation, and
Unicom Corporation, an Illinois corporation.  Capitalized terms used but not
defined in this letter have the meanings give such terms in the Merger
Agreement.

          The undersigned, a holder of shares of Company Common Stock, is
entitled to receive in connection with the Merger shares of Newco Common Stock.
The undersigned acknowledges that the undersigned may be deemed an "affiliate"
of the Company within the meaning of Rule 145 ("Rule 145") promulgated under the
Securities Act, although nothing contained herein should be construed as an
admission of such fact.

          If in fact the undersigned were an affiliate under the Securities Act,
the undersigned's ability to sell, assign or transfer the Newco Common Stock
received by the undersigned in exchange for any shares of Company Common Stock
pursuant to the Merger may be restricted unless such transaction is registered
under the Securities Act or an exemption from such registration is available.
The undersigned (i) understands that such exemptions are limited and that Newco
is not under any obligation to effect any such registration and (ii) has
obtained advice of counsel as to the nature and conditions of such exemptions,
including information with respect to the applicability to the sale of such
securities of Rules 144 and 145(d) promulgated under the Securities Act.

          The undersigned hereby represents to and covenants with Parent and
Newco that the undersigned will not sell,
<PAGE>

                                                                               2

assign or transfer any of the Newco Common Stock received by the undersigned in
exchange for shares of Company Common Stock pursuant to the Merger except (i)
pursuant to an effective registration statement under the Securities Act or (ii)
in a transaction that, in the opinion of counsel reasonably satisfactory to
Newco or as described in a "no-action" or interpretive letter from the Staff of
the SEC, is not required to be registered under the Securities Act.

          In the event of a sale or other disposition by the undersigned
pursuant to Rule 145, of Newco Common Stock received by the undersigned in the
Merger, the undersigned will supply Newco with evidence of compliance with such
Rule, in the form of a letter in the form of Annex I hereto and the opinion of
counsel or no-action letter referred to above. The undersigned understands that
Newco may instruct its transfer agent to withhold the transfer of any Parent
securities disposed of by the undersigned, but that upon receipt of such
evidence of compliance the transfer agent shall effectuate the transfer of the
Newco Common Stock sold as indicated in the letter.

          The undersigned acknowledges and agrees that (i) the Newco Common
Stock issued to the undersigned will all be in certificated form and (ii)
appropriate legends will be placed on certificates representing Newco Common
Stock received by the undersigned in the Merger or held by a transferee thereof,
which legends will be removed by delivery of substitute certificates upon
receipt of an opinion in form and substance reasonably satisfactory to Newco
from counsel reasonably satisfactory to Newco to the effect that such legends
are no longer required for purposes of the Securities Act.

          The undersigned acknowledges that (i) the undersigned has carefully

                        Form of Parent Affiliate Letter


Dear Sirs:

          The undersigned refers to the Amended and Restated Agreement and Plan
of Exchange and Merger (the "Merger Agreement") dated as of September 22, 1999,
as amended and restated as of January 7, 2000, among PECO Energy Company, a
Pennsylvania corporation, Newholdco Corporation, a Pennsylvania corporation, and
Unicom Corporation, an Illinois corporation.  Capitalized terms used but not
defined in this letter have the meanings give such terms in the Merger
Agreement.

          The undersigned, a holder of shares of Parent Common Stock, is
entitled to receive in connection with the Merger shares of Newco Common Stock.
The undersigned acknowledges that the undersigned may be deemed an "affiliate"
of Parent within the meaning of Rule 145 ("Rule 145") promulgated under the
Securities Act, although nothing contained herein should be construed as an
admission of such fact.

          If in fact the undersigned were an affiliate under the Securities Act,
the undersigned's ability to sell, assign or transfer the Newco Common Stock
received by the undersigned in exchange for any shares of Parent Common Stock
pursuant to the Merger may be restricted unless such transaction is registered
under the Securities Act or an exemption from such registration is available.
The undersigned (i) understands that such exemptions are limited and that Newco
is not under any obligation to effect any such registration and (ii) has
obtained advice of counsel as to the nature and conditions of such exemptions,
including information with respect to the applicability to the sale of such
securities of Rules 144 and 145(d) promulgated under the Securities Act.

          The undersigned hereby represents to and covenants with the Company
and Newco that the undersigned will not sell, assign or transfer any of the
Newco Common Stock
<PAGE>

                                                                               2

received by the undersigned in exchange for shares of Parent Common Stock
pursuant to the Merger except (i) pursuant to an effective registration
statement under the Securities Act or (ii) in a transaction that, in the opinion
of counsel reasonably satisfactory to Newco or as described in a "no-action" or
interpretive letter from the Staff of the SEC, is not required to be registered
under the Securities Act.

          In the event of a sale or other disposition by the undersigned
pursuant to Rule 145, of Newco Common Stock received by the undersigned in the
Merger, the undersigned will supply Newco with evidence of compliance with such
Rule, in the form of a letter in the form of Annex I hereto and the opinion of
counsel or no-action letter referred to above. The undersigned understands that
Newco may instruct its transfer agent to withhold the transfer of any Parent
securities disposed of by the undersigned, but that upon receipt of such
evidence of compliance the transfer agent shall effectuate the transfer of the
Newco Common Stock sold as indicated in the letter.

          The undersigned acknowledges and agrees that (i) the Newco Common
Stock issued to the undersigned will all be in certificated form and (ii)
appropriate legends will be placed on certificates representing Newco Common
Stock received by the undersigned in the Merger or held by a transferee thereof,
which legends will be removed by delivery of substitute certificates upon
receipt of an opinion in form and substance reasonably satisfactory to Newco
from counsel reasonably satisfactory to Newco to the effect that such legends
are no longer required for purposes of the Securities Act.

          The undersigned acknowledges that (i) the undersigned has carefully
read this letter and understands the requirements hereof and the limitations
imposed upon the distribution, sale, transfer or other disposition of Parent
Common Stock and (ii) the receipt by the Company and Newco of this letter is an
inducement and a condition to Company's obligations to consummate the Merger.

Ladies and Gentlemen:

          In connection with the opinions to be delivered pursuant to Sections
7.02(d) and 7.03(d) of the Amended and Restated Agreement and Plan of Exchange
and Merger (the "Exchange and Merger Agreement") dated as of September 22, 1999,
as amended and restated as of January 7, 2000, among PECO Energy Company, a
Pennsylvania corporation ("Parent"), Newholdco Corporation, a Pennsylvania
corporation and a wholly owned subsidiary of Parent ("Newco") and Unicom
Corporation, an Illinois corporation (the "Company"), and in connection with the
filing with the Securities and Exchange Commission (the "SEC") of the
registration statement on Form S-4 (the "Registration Statement"), which
includes the proxy statement/prospectus of Parent and the Company, each as
amended and supplemented through the date hereof, the undersigned certifies and
represents on behalf of Parent and as to Parent, after due inquiry and
investigation, as follows (any capitalized term used but not defined herein
having the meaning given to such term in the Exchange and Merger Agreement):

          1.  The Merger will be consummated in accordance with the Exchange and
Merger Agreement and as described in the Registration Statement.  The facts
relating to the Merger as described in the Registration Statement and the
documents referenced in the Registration Statement are, insofar as such facts
relate to Parent, true, correct and complete in all material respects.
<PAGE>

                                                                               2

          2.  The formula set forth in the Exchange and Merger Agreement
pursuant to which each issued and outstanding share of common stock, no par
value, of Parent (the "Parent Common Stock") will be converted into common
shares, no par value, of Newco (the "Newco Common Stock") is the result of arm's
length bargaining.  The aggregate fair market value of the Newco Common Stock to
be received by each holder of Parent Common Stock in the First Step Exchange
will be approximately equal to the fair market value of the Parent Common Stock
surrendered in exchange therefor.

          3.  Parent has not made and does not have any present plan or
intention to make any distributions to holders of Parent Common Stock (other
than dividends in the ordinary course of business) prior to, in contemplation
of, or otherwise in connection with, the Merger.

          4.  Newco has not acquired, nor, except as a result of the First Step
Exchange will it acquire, nor has it owned in the past five years, any Parent
Common Stock.

          5.  Parent, Newco and the holders of Parent Common Stock will each pay
their respective expenses, if any, incurred in connection with the First Step
Exchange.  Parent has not agreed to assume, nor will it directly or indirectly
assume, any expense or other liability, whether fixed or contingent, of any
holder of Parent Common Stock.  Parent has not entered into any arrangement
pursuant to which Newco  has agreed to assume, directly or indirectly, any
expense or other liability, whether fixed or contingent, incurred or to be
incurred by Parent or any holder of Parent Common Stock in connection with or as
part of the First Step Exchange or any related transactions, nor will any of the
Parent Common Stock that is acquired by Newco in connection with the First Step
Exchange be subject to any liabilities.

          6.  Parent is not an investment company as defined in Section
368(a)(2)(F)(iii) and (iv) of the Internal Revenue Code of 1986, as amended (the
"Code"), Section 351(e)(1) of the Code or Treasury Regulation Section 1.351-
1(c)(1)(ii).

          7.  Parent will not take, and, to the best knowledge of the management
of Parent there is no present plan or intention of any holders of Parent Common
Stock to take, any position on any Federal, state or local income or franchise
tax return, or take any other tax reporting position, that is inconsistent (i)
with the treatment of the Merger as transactions described in Section 351 of the
Code or (ii) with the treatment of the Second Step Merger as a
<PAGE>

                                                                               3

reorganization within the meaning of Section 368(a) of the Code, in each case
unless otherwise required by a "determination" (as defined in Section 1313(a)(1)
of the Code) or by applicable state or local tax law (and then only to the
extent required by such applicable state or local tax law).

          8.  None of the compensation received by any stockholder-employee of
Parent in respect of periods ending on or prior to the Exchange Effective Time
represents separate consideration for any of his or her Parent Common Stock.
None of the Newco Common Stock that will be received by any stockholder-employee
of Parent in the Merger represents separately bargained for consideration which
is allocable to any employment agreement or arrangement.  The compensation paid
to any stockholder-employees will be for services actually rendered and will be
determined by bargaining at arm's-length.

          9.   There is no intercorporate indebtedness existing between Newco
and Parent.

          10.  Parent is not under the jurisdiction of a court in a Title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code.

          11.  On the date of the First Step Exchange, the fair market value of
the assets of Parent will exceed the sum of its liabilities, plus the amount of
liabilities, if any, to which such assets are subject.

          12.  To the best knowledge of the management of Parent, there is no
present plan or intention on the part of the holders of Parent Common Stock to
sell, exchange or otherwise dispose of, or to enter into any contract or other
arrangement with respect to, any interest in the shares of Newco Common Stock
received in the First Step Exchange in exchange for such Parent Common Stock
such that the former holders of Company Common Stock and the former holders of
Parent Common Stock, in the aggregate, would not own (i) Newco Common Stock
having at least 80% of the total combined voting power of all classes of Newco
stock entitled to vote and (ii) at least 80% of the total number of shares of
each other class of Newco Stock.

          13.  None of the holders of Parent Common Stock will retain any rights
in the Parent Common Stock transferred to Newco pursuant to the First Step
Exchange.
<PAGE>

                                                                               4

          14.  Newco will not receive any accounts receivable in the First Step
Exchange.

          15.  To the best knowledge of the management of Parent and taking into
account any issuance of additional shares of Newco Common Stock, any issuance of
Newco Common Stock for services, the exercise of any Newco stock rights,
options, warrants or subscriptions, any public offerings of Newco stock, and the
sale, exchange, transfer by gift or other disposition of any Newco Common Stock
received by holders of Parent Common Stock in the Merger, the holders of Parent
Common Stock and Company Common Stock will collectively be in "control" of Newco
immediately after the Merger.  For purposes of this representation letter,
"control" shall mean the ownership of (i) stock possessing at least 80% of the
total combined voting power of all classes of Newco stock entitled to vote and
(ii) at least 80% of the total number of shares of each other class of Newco
stock.

          16.  The Exchange and Merger Agreement, the Registration Statement and
the other documents described in the Registration Statement represent the entire
understanding of Parent with respect to the Merger and there are no other
written or oral agreements regarding the Merger.

          17.  The Merger is being undertaken for purposes of enhancing the
business of Parent and for other good and valid business purposes of Parent as
described in the proxy statement/prospectus of Parent and the Company included
in the Registration Statement.

          18.  The undersigned is authorized to make all the representations set
forth herein on behalf of Parent.

          The undersigned acknowledges that (i) the opinions to be delivered
pursuant to Sections 7.02(d) and 7.03(d) of the Exchange and Merger Agreement
will be based on the accuracy of the representations set forth herein and on the
accuracy of the representations and warranties and the satisfaction of the
covenants and obligations contained in the Exchange and Merger Agreement and the
various other documents related thereto, and (ii) such opinions will be subject
to certain limitations and qualifications including that they may not be relied
upon if any such representations or warranties are not accurate or if any such
covenants or obligations are not satisfied in all material respects.

          The undersigned acknowledges that such opinions will not address any
tax consequences of the Merger or any

     action taken in connection therewith except as expressly set forth in such
     opinions.

     Ladies and Gentlemen:

               In connection with the opinions to be delivered pursuant to
     Sections 7.02(d) and 7.03(d) of the Amended and Restated Agreement and Plan
     of Exchange and Merger (the "Exchange and Merger Agreement") dated as of
     September 22, 1999, as amended and restated as of January 7, 2000, among
     PECO Energy Company, a Pennsylvania corporation ("Parent"), Newholdco
     Corporation, a Pennsylvania corporation and a wholly owned subsidiary of
     Parent ("Newco") and Unicom Corporation, an Illinois corporation (the
     "Company"), and in connection with the filing with the Securities and
     Exchange Commission (the "SEC") of the registration statement on Form S-4
     (the "Registration Statement"), which includes the proxy
     statement/prospectus of Parent and the Company, each as amended and
     supplemented through the date hereof, the undersigned certifies and
     represents on behalf of Newco and as to Newco, after due inquiry and
     investigation, as follows (any capitalized term used but not defined herein
     having the meaning given to such term in the Exchange and Merger
     Agreement):

               1. The Merger will be consummated in accordance with the Exchange
     and Merger Agreement and as described in the Registration Statement. The
     facts relating to the Merger as described in the Registration Statement and
     the documents referenced in the Registration Statement are, insofar as such

<PAGE>

                                                                               2

     facts relate to Newco, true, correct and complete in all material respects.

               2. The formulae set forth in the Exchange and Merger Agreement
     pursuant to which each issued and outstanding share of common stock, no par
     value, of Parent (the "Parent Common Stock") will be converted into common
     shares, no par value, of Newco (the "Newco Common Stock") and each issued
     and outstanding share of common stock, no par value, of the Company (the
     "Company Common Stock") will be converted into Newco Common Stock and cash
     are the result of arm's length bargaining. The aggregate fair market value
     of the Newco Common Stock to be received by holders of Parent Common Stock
     in the Merger will be approximately equal to the fair market value of the
     Parent Common Stock surrendered in exchange therefor. The aggregate fair
     market value of the Newco Common Stock and cash to be received by holders
     of Company Common Stock in the Merger will be approximately equal to the
     fair market value of the Company Common Stock surrendered in exchange
     therefor.

               3. Cash payments, if any, to be made to holders of Company Common
     Stock in lieu of fractional shares of Newco Common Stock that would
     otherwise be issued to such holders in the Second Step Merger will be made
     for the purpose of saving Newco the expense and inconvenience of issuing
     and transferring fractional shares of Newco Common Stock, and do not
     represent separately bargained for consideration. The total cash
     consideration that will be paid in the Second Step Merger to holders of
     Company Common Stock in lieu of fractional shares of Newco Common Stock is
     not expected to exceed one percent of the total consideration that will be
     issued in the Second Step Merger to such holders in exchange for their
     shares of Company Common Stock.

               4. (i) Newco has no present plan or intention, following the
     Merger, to reacquire, or to cause any corporation that is related to Newco
     to acquire, directly or indirectly, any Newco Common Stock issued in the
     Merger, except for repurchases of Newco Common Stock by Newco in connection
     with [describe specific parameters of any repurchase program to be adopted
     by Newco]. No corporation that is related to Newco has a plan or intention
     to purchase any of the Newco Common Stock issued in the Merger.

               (ii) For purposes of this representation letter, a corporation
     shall be treated as related to Newco if such corporation is related to
     Newco within the meaning of Treasury Regulation Section 1.368-1(e)(3).
<PAGE>

                                                                               3

               5. Newco has not acquired, nor, except as a result of the First
     Step Exchange will it acquire, nor has it owned in the past five years, any
     Parent Common Stock. Newco has not acquired, nor, except as a result of the
     Second Step Merger will it acquire, nor has it owned in the past five
     years, any Company Common Stock.

               6. Newco has no present plan or intention to make any
     distributions after the Merger to holders of Newco Common Stock (other than
     dividends made in the ordinary course of business).

               7. At the Merger Effective Time, the value of the Newco Common
     Stock to be issued to holders of Company Common Stock in the Second Step
     Merger will represent at least 50% of the value of the total consideration
     to be issued to such holders in the Second Step Merger in exchange for
     their shares of Company Common Stock. Further, no liabilities of Parent or
     any of the holders of Parent Common Stock and no liabilities of any of the
     holders of Company Common Stock will be assumed by Newco, nor will any of
     the Parent Common Stock or Company Common Stock acquired by Newco in
     connection with the Merger be subject to any liabilities.

               8. Parent, Newco, the Company and holders of Parent Common Stock
     and Company Common Stock will each pay their respective expenses, if any,
     incurred in connection with the Merger. Newco has not paid, directly or
     indirectly, nor has it agreed to assume any expense or other liability,
     whether fixed or contingent, incurred or to be incurred by Parent, any
     holder of Parent Common Stock or any holder of Company Common Stock in
     connection with or as part of the Merger or any related transactions.

               9. Following the Second Step Merger, Newco or Newco's "qualified
     group" of corporations (as defined in Treasury Regulation Section 1.368-
     1(d)(4)(ii)) will continue the "historic business" of the Company or use a
     significant portion of the Company's "historic business assets" in a
     business (as such terms are defined in Treasury Regulation Section 1.368-
     1(d)). Following the First Step Exchange, Newco will cause Parent to
     continue its historic business or to use a significant portion of its
     historic business assets in a trade or business.

               10. Newco is not an investment company as defined in Section
     368(a)(2)(F)(iii) and (iv) of the Code, Section 351(e)(1) of the Code or
     Treasury Regulation Section 1.351-1(c)(1)(ii).

                                                                               4

               11. Newco will not take any position on any Federal, state or
     local income or franchise tax return, or take any other tax reporting
     position, that is inconsistent (i) with the treatment of the Merger as
     transactions described in Section 351 of the Code or (ii) with the
     treatment of the Second Step Merger as a reorganization within the meaning
     of Section 368(a) of the Code, in each case unless otherwise required by a
     "determination" (as defined in Section 1313(a)(1) of the Code) or by
     applicable state or local tax law (and then only to the extent required by
     such applicable state or local tax law).

               12. None of the compensation received by any stockholder-employee
     of Parent in respect of periods ending on or prior to the Exchange
     Effective Time represents separate consideration for any of his or her
     Parent Common Stock. None of the compensation received by any stockholder-
     employee of the Company in respect of periods ending on or prior to the
     Merger Effective Time represents separate consideration for any of his or
     her Company Common Stock. None of the Newco Common Stock that will be
     received by any stockholder-employee of Parent or the Company in the Merger
     represents separately bargained for consideration which is allocable to any
     employment agreement or arrangement. The compensation paid to any
     stockholder-employees will be for services actually rendered and will be
     determined by bargaining at arm's-length.

               13. There is no intercorporate indebtedness existing between (i)
     Newco and Parent or (ii) Newco (or any of its subsidiaries) and the Company
     (or any of its subsidiaries).

               14. Newco is not under the jurisdiction of a court in a Title 11
     or similar case within the meaning of Section 368(a)(3)(A) of the Code.

               15. To the best knowledge of the management of Newco and taking
     into account any issuance of additional shares of Newco Common Stock, any
     issuance of Newco Common Stock for services, the exercise of any Newco
     stock rights, options, warrants or subscriptions, any public offerings of
     Newco stock, and the sale, exchange, transfer by gift or other disposition
     of any Newco Common Stock received in the Merger, the holders of Parent
     Common Stock and Company Common Stock will collectively be in "control" of
     Newco immediately after the Merger. For purposes of this representation
     letter, "control" shall mean the ownership of (i) stock possessing at least
     80% of the total combined voting power of all classes of Newco stock
     entitled to vote and (ii) at least
<PAGE>

                                                                               5

     80% of the total number of shares of each other class of Newco stock.

               16. Newco has no present plan or intention to, or to cause any of
     its affiliates to, (i) liquidate Newco or Parent, (ii) merge (other than in
     connection with the Second Step Merger), liquidate or consolidate Newco or
     Parent with or into any other entity (including, without limitation, any
     affiliate), (iii) sell, transfer, distribute or otherwise dispose of the
     Parent Common Stock or interests in any of its material affiliates or (iv)
     sell, transfer, distribute or otherwise dispose of any of the material
     assets of Parent, the Company or their affiliates acquired in the Merger
     (other than in the ordinary course of business or transfers described in
     Section 368(a)(2)(C) of the Code or Treasury Regulation Section 1.368-2(k)
     that also qualify as transactions described in Section 351 of the Code).

               17. The Newco Common Stock issued in the Merger will constitute
     all of Newco's outstanding stock immediately after the Merger. Except as
     specifically set forth in the Exchange and Merger Agreement, Newco will not
     issue any Newco Common Stock in connection with the Merger in consideration
     for services rendered to or for the benefit of Newco or any of its
     affiliates, or in consideration for the transfer of any property other than
     Parent Common Stock or Company assets.

               18. The Exchange and Merger Agreement, the Registration Statement
     and the other documents described in the Registration Statement represent
     the entire understanding of Newco with respect to the Merger and there are
     no other written or oral agreements regarding the Merger.

               19. The Merger is being undertaken for purposes of enhancing the
     business of Newco and for other good and valid business purposes of Newco
     as described in the proxy statement/prospectus of Parent and the Company
     included in the Registration Statement.

               20. Newco is not a personal service corporation within the
     meaning of Section 269A of the Code.

               21. The undersigned is authorized to make all the representations
     set forth herein on behalf of Newco.

               The undersigned acknowledges that (i) the opinions to be
     delivered pursuant to Sections 7.02(d) and 7.03(d) of the Exchange and
     Merger Agreement will be based on the accuracy of the representations set
     forth herein and on the

     accuracy of the representations and warranties and the satisfaction of the
     covenants and obligations contained in the Exchange and Merger Agreement
     and the various other documents related thereto, and (ii) such opinions
     will be subject to certain limitations and qualifications including that
     they may not be relied upon if any such representations or warranties are
     not accurate or if any such covenants or obligations are not satisfied in
     all material respects.

               The undersigned acknowledges that such opinions will not address
     any tax consequences of the Merger or any action taken in connection
     therewith except as expressly set forth in such opinions.

                                  Very truly yours,

                          [Letterhead of the Company]

     Ladies and Gentlemen:

               In connection with the opinions to be delivered pursuant to
     Sections 7.02(d) and 7.03(d) of the Amended and Restated Agreement and Plan
     of Exchange and Merger (the "Exchange and Merger Agreement") dated as of
     September 22, 1999, as amended and restated as of January 7, 2000, among
     PECO Energy Company, a Pennsylvania corporation ("Parent"), Newholdco
     Corporation, a Pennsylvania corporation and a wholly owned subsidiary of
     Parent ("Newco") and Unicom Corporation, an Illinois corporation (the
     "Company"), and in connection with the filing with the Securities and
     Exchange Commission (the "SEC") of the registration statement on Form S-4
     (the "Registration Statement"), which includes the proxy
     statement/prospectus of Parent and the Company, each as amended and
     supplemented through the date hereof, the undersigned certifies and
     represents on behalf of the Company and as to the Company, after due
     inquiry and investigation, as follows (any capitalized term used but not
     defined herein having the meaning given to such term in the Exchange and
     Merger Agreement):

               1. The Merger will be consummated in accordance with the Exchange
     and Merger Agreement and as described in the Registration Statement. The
     facts relating to the Merger as described in the Registration Statement and
     the documents referenced in the Registration Statement are, insofar as such
<PAGE>

                                                                               2

     facts relate to the Company, true, correct and complete in all material
     respects.

               2. The formula set forth in the Exchange and Merger Agreement
     pursuant to which each issued and outstanding share of common stock, no par
     value, of the Company (the "Company Common Stock") will be converted into
     common shares, no par value, of Newco (the "Newco Common Stock") and cash
     is the result of arm's length bargaining. The aggregate fair market value
     of the Newco Common Stock and cash to be received by each holder of Company
     Common Stock in the Second Step Merger will be approximately equal to the
     fair market value of the Company Common Stock surrendered in exchange
     therefor.

               3. Cash payments, if any, to be made to holders of Company Common
     Stock in lieu of fractional shares of Newco Common Stock that would
     otherwise be issued to such holders in the Second Step Merger will be made
     for the purpose of saving Newco the expense and inconvenience of issuing
     and transferring fractional shares of Newco Common Stock, and do not
     represent separately bargained for consideration. The total cash
     consideration that will be paid in the Second Step Merger to holders of
     Company Common Stock in lieu of fractional shares of Newco Common Stock is
     not expected to exceed one percent of the total consideration that will be
     issued in the Second Step Merger to such holders in exchange for their
     shares of Company Common Stock.

               4. (i)  Except to the extent specifically contemplated under the
     Exchange and Merger Agreement, neither the Company nor any corporation
     related to the Company has acquired or has any present plan or intention to
     acquire, directly or indirectly, any Company Common Stock in contemplation
     of the Merger, or otherwise as part of a plan of which the Merger is a
     part.

                  (ii) For purposes of this representation letter, a corporation
     shall be treated as related to the Company if such corporation is related
     to the Company within the meaning of Treasury Regulation Section
     1.368-1(e)(3) (determined without regard to Treasury Regulation Section
     1.368-1(e)(3)(i)(A)).

               5. The Company has not made and does not have any present plan or
     intention to make any distributions (other than dividends made in the
     ordinary course of business) to holders of Company Common Stock prior to,
     in contemplation of, or otherwise in connection with, the Merger.

                                                                               3

               6. Newco, the Company and holders of Company Common Stock will
     each pay their respective expenses, if any, incurred in connection with the
     Second Step Merger. The Company has not agreed to assume, nor will it
     directly or indirectly assume, any expense or other liability, whether
     fixed or contingent, of any holder of Company Common Stock. Further, no
     liabilities of any of the holders of Company Common Stock will be assumed
     by Newco, nor will any of the Company Common Stock acquired by Newco in
     connection with the Merger be subject to any liabilities.

               7. Any liabilities of the Company that will be assumed by Newco
     pursuant to the Merger, and any liabilities to which the assets of the
     Company that will be transferred to Newco pursuant to the Merger are
     subject, were incurred in the ordinary course of business and are
     associated with the assets of the Company.

               8. At the Merger Effective Time, the value of the Newco Common
     Stock issued to the holders of Company Common Stock in the Second Step
     Merger will represent at least 50% of the value of the total consideration
     issued to such holders in the Second Step Merger in exchange for their
     shares of Company Common Stock.

               9. The Company is not an investment company as defined in Section
     368(a)(2)(F)(iii) and (iv) of the Internal Revenue Code of 1986, as amended
     (the "Code"), Section 351(e)(1) of the Code or Treasury Regulation Section
     1.351-1(c)(1)(ii).

               10. The Company will not take, and to the best knowledge of the
     management of the Company there is no present plan or intention by holders
     of Company Common Stock to take, any position on any Federal, state or
     local income or franchise tax return, or to take any other tax reporting
     position, that is inconsistent (i) with the treatment of the Merger as
     transactions described in Section 351 of the Code or (ii) with the
     treatment of the Second Step Merger as a reorganization within the meaning
     of Section 368(a) of the Code, in each case unless otherwise required by a
     "determination" (as defined in Section 1313(a)(1) of the Code) or by
     applicable state or local tax law (and then only to the extent required by
     such applicable state or local tax law).

               11. None of the compensation received by any stockholder-employee
     of the Company in respect of periods ending on or prior to the Merger
     Effective Time represents separate consideration for any of his or her
     Company Common
<PAGE>

                                                                               4

     Stock. None of the Newco Common Stock that will be received by any
     stockholder-employee of the Company in the Merger represents separately
     bargained for consideration which is allocable to any employment agreement
     or arrangement. The compensation paid to any stockholder-employees will be
     for services actually rendered and will be determined by bargaining at
     arm's-length.

               12. There is no intercorporate indebtedness existing between
     Newco (or any of its subsidiaries, including Parent) and the Company (or
     any of its subsidiaries).

               13. The Company is not under the jurisdiction of a court in a
     Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the
     Code.

               14. No assets of the Company have been sold, transferred or
     otherwise disposed of which would prevent Newco or Newco's "qualified
     group" of corporations (as defined in Treasury Regulation Section
     1.368-1(d)(4)(ii)) from continuing the "historic business" of the Company
     or from using a significant portion of the "historic business assets" of
     the Company in a business following the Merger (as such terms are defined
     in Treasury Regulation Section 1.368-1(d)).

               15. At the Merger Effective Time, the fair market value of the
     assets of the Company transferred to Newco pursuant to the Second Step
     Merger will exceed the sum of its liabilities assumed by Newco pursuant to
     the Second Step Merger, plus the amount of liabilities, if any, to which
     such assets are subject.

               16. To the best knowledge of the management of the Company, there
     is no present plan or intention on the part of the holders of Company
     Common Stock to sell, exchange or otherwise dispose of, or to enter into
     any contract or other arrangement with respect to, any interest in the
     shares of Newco Common Stock received in the Second Step Merger in exchange
     for such Company Common Stock such that the former holders of Company
     Common Stock and the former holders of Parent Common Stock, in the
     aggregate, would not own (i) Newco Common Stock having at least 80% of the
     total combined voting power of all classes of Newco stock entitled to vote
     and (ii) at least 80% of the total number of shares of each other class of
     Newco Stock.

               17. The Company will not retain any rights in the Company assets
     transferred to Newco pursuant to the Second Step Merger.

                                                                               5

               18. None of the stock of any Company Subsidiary being transferred
     in the Second Step Merger is Section 306 stock within the meaning of
     Section 306(c) of the Code.

               19. Neither the Company nor any Company Subsidiary has been a
     "distributing corporation" or a "controlled corporation" in a distribution
     of stock qualifying for tax-free treatment under Section 355 of the Code
     (i) at any time during the two-year period prior to the date of the
     Exchange and Merger Agreement, (ii) at any time during the period
     commencing on the date of the Exchange and Merger Agreement and ending on
     the date hereof or (iii) which could otherwise constitute part of a "plan"
     or "series of related transactions" (within the meaning of Section 355(e)
     of the Code) in conjunction with and including the Merger.

               20. To the best knowledge of the management of the Company and
     taking into account any issuance of additional shares of Newco Common
     Stock, any issuance of Newco Common Stock for services, the exercise of any
     Newco stock rights, options, warrants or subscriptions, any public
     offerings of Newco stock, and the sale, exchange, transfer by gift or other
     disposition of any Newco Common Stock received by holders of Company Common
     Stock in the Merger, the holders of Parent Common Stock and Company Common
     Stock will collectively be in "control" of Newco immediately after the
     Merger. For purposes of this representation letter, "control" shall mean
     the ownership of (i) stock possessing at least 80% of the total combined
     voting power of all classes of Newco stock entitled to vote and (ii) at
     least 80% of the total number of shares of each other class of Newco stock.

               21. The Merger is being undertaken for purposes of enhancing the
     business of the Company and for other good and valid business purposes of
     the Company as described in the proxy statement/prospectus of Parent and
     the Company included in the Registration Statement.

               22. The Exchange and Merger Agreement, the Registration Statement
     and the other documents described in the Registration Statement represent
     the entire understanding of the Company with respect to the Merger and
     there are no other written or oral agreements regarding the Merger.

               23. The undersigned is authorized to make all the representations
     set forth herein on behalf of the Company.

               The undersigned acknowledges that (i) the opinions to be
     delivered pursuant to Sections 7.02(d) and 7.03(d) of the Exchange and
     Merger Agreement will be based on the

     accuracy of the representations set forth herein and on the accuracy of the
     representations and warranties and the satisfaction of the covenants and
     obligations contained in the Exchange and Merger Agreement and the various
     other documents related thereto, and (ii) such opinions will be subject to
     certain limitations and qualifications including that they may not be
     relied upon if any such representations or warranties are not accurate or
     if any of such covenants or obligations are not satisfied in all material
     respects.

               The undersigned acknowledges that such opinions will not address
     any tax consequences of the Merger or any action taken in connection
     therewith except as expressly set forth in such opinions.
