                            -----------------------

          SECTION 1.01.  The Exchange and Merger.  (a)  On the terms and subject
to the conditions set forth in this Agreement, in accordance with the Business

          (b)  On the terms and subject to the conditions set forth in this
Agreement, in accordance with the Illinois Business Corporation Act (the "IBCA")
and the PBCL, the Company shall be merged with and into Newco at the Merger
Effective Time (as defined in Section 1.03).  At the Merger Effective Time, the
separate corporate existence of the Company shall cease and Newco shall continue
as the surviving corporation (the "Surviving Corporation").

          (c)  The First Step Exchange, the Second Step Merger, the issuance by
Newco of Newco Common Stock in connection with the Merger (the "Share Issuance")
and the other transactions contemplated by this Agreement are referred to in
this Agreement collectively as the "Transactions".

set forth in Section 7.02 or 7.03 has not been satisfied (or, to the extent
permitted by Applicable Law, waived by the party or parties entitled to the
benefits thereof), as soon as practicable after all the conditions set forth in
Article VII have been satisfied (or, to the extent permitted by Applicable Law,
waived by the parties entitled to the

their respective successors, as the case may be.

          (b)  In accordance with the Newco By-laws, as amended pursuant to
Section 1.05(b), as of the Merger Effective Time, the Board of Directors of the
Surviving Corporation (the "Newco Board") shall consist of 16 members, eight of
whom shall be serving as members of the Board of Directors of Parent immediately

          (b)   Charities.  The parties agree that provision of charitable
contribution and community support in the respective service areas of Parent and

goals. During the two-year period immediately following the Merger Effective
Time, the Surviving Corporation shall provide, directly or indirectly,
charitable contributions and traditional local community support within the
respective service areas of Parent and the Company and each of their
subsidiaries that are utilities at levels substantially comparable to and no

          SECTION 2.01.  Effect on Capital Stock. (a)  First Step Exchange.  At
the Exchange Effective Time, by virtue of the First Step Exchange and without
any action on the part of the holder of any shares of Parent Common Stock or
Newco Common Stock:

          (i)  Cancelation of Treasury Stock.  Each share of Parent Common Stock
     that is owned by Parent shall automatically be canceled and retired and
     shall cease to exist, and no Newco Common Stock or other
<PAGE>

                                                                               6



     consideration shall be delivered or deliverable in exchange therefor.

          (ii) Exchange of Parent Common Stock. (A) Subject to Section
     2.01(a)(i) and Section 2.02(a)(iii), each issued share of Parent Common
     Stock shall be exchanged for either (1) $45.00 in cash (the "Parent Cash
     Consideration") or (2) one fully paid and nonassessable share of Newco
     Common Stock (the "Parent Exchange Ratio"), in each case as the holder
     thereof shall have elected or be deemed to have elected, in accordance with
     Section 2.01(a)(iv).

               (B)  The Parent Cash Consideration and 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 shares of
          Parent Common Stock shall cease to have any rights with respect
          thereto, except the right to receive Exchange Consideration upon
          surrender of such certificate in accordance with Section 2.02, without
          interest.

          (iii)  Allocation.  Notwithstanding anything in this Agreement to the
     contrary, the number of shares of Parent Common Stock to be converted into
     the right to receive the Parent Cash Consideration in the First Step
     Exchange (the "Parent Cash Number") will be equal to 16,666,666 shares of
     Parent Common Stock.  The number of shares of Parent Common Stock to be
     converted into the right to receive the Parent Stock Consideration in the
     First Step Exchange (the "Parent Stock Number") will be equal to (A) the
     number of shares of Parent Common Stock issued and outstanding immediately
     prior to the Exchange Effective Time (ignoring for this purpose any Parent
     Common Stock to be canceled pursuant to Section 2.01(a)(i)) less (B) the
     Parent Cash Number.

          (iv)  Election.  Subject to allocation in accordance with the
     provisions of this Section 2.01(a), each record holder of shares of Parent
     Common Stock
<PAGE>

                                                                               7


     (other than shares to be canceled in accordance with Section 2.01(a)(i))
     issued and outstanding immediately prior to the Election Deadline (as
     defined in Section 2.02(b)) will be entitled, in accordance with Section
     2.02(b), (i) to elect to receive in respect of each such share (A) the
     Parent Cash Consideration (a "Parent Cash Election") or (B) the Parent
     Stock Consideration (a "Parent Stock Election") or (ii) to indicate that
     such record holder has no preference as to the receipt of the Parent Cash
     Consideration or the Parent Stock Consideration for all such shares held by
     such holder (a "Parent Non-Election"); provided, however, that record
     holders of Parent Common Stock who own, as of the date of the Election
     Deadline, less than 100 shares of Parent Common Stock in respect of which a
     Parent Non-Election is made or no election is made (all such shares,
     collectively with Parent Odd Lot Cash Election Shares (as hereinafter
     defined) being herein referred to as the "Parent Deminimis Shares"), will
     be deemed to have elected to receive the Parent Cash Consideration for such
     shares. "Parent Odd Lot Cash Election Shares" means shares of Parent Common
     Stock held by record holders of Parent Common Stock who, as of the date of
     the Election Deadline, own less than 100 shares of Parent Common Stock and
     have made Parent Cash Elections in respect of all such shares.

          (v)   Allocation of Parent Cash Election Shares. In the event that the
     aggregate number of shares in respect of which Parent Cash Elections have
     been made or are deemed to have been made in accordance with the proviso at
     the end of the first sentence of Section 2.01(a)(iv) (the "Parent Cash
     Election Shares") exceeds the Parent Cash Number, all shares of Parent
     Common Stock in respect of which Parent Stock Elections have been made
     ("the Parent Stock Election Shares") and all Parent Non-Election Shares (as
     defined in Section 2.01(a)(vii)) will be converted into the right to
     receive the Parent Stock Consideration, and the Parent Cash Election Shares
     will be converted into the right to receive the Parent Cash Consideration
     or the Parent Stock Consideration in the following manner:

               (A) all Parent Deminimis Shares will be converted into the right
          to receive the Parent Cash Consideration;
<PAGE>

                                                                               8



               (B) the number of Parent Cash Election Shares, other than Parent
          Deminimis Shares, covered by each Form of Election (as defined in
          Section 2.02(b)) to be converted into Parent Cash Consideration will
          be determined by multiplying the number of Parent Cash Election Shares
          covered by such Form of Election by a fraction, (A) the numerator of
          which is the Parent Cash Number less the number of Parent Deminimis
          Shares and (B) the denominator of which is the aggregate number of
          Parent Cash Election Shares less the number of Parent Deminimis
          Shares, rounded down to the nearest whole number; provided, however,
          that, if as a result of such proration, any holder of Parent Cash
          Election Shares would, but for this proviso, receive less than 100
          shares of Newco Common Stock in accordance with Section 2.01(a)(v)(C),
          all Parent Cash Election Shares held by such holders (the "Parent Non-
          Prorated Cash Shares") will be converted into the Parent Cash
          Consideration and the remaining Parent Cash Election Shares to be
          converted into the Parent Cash Consideration will be determined by
          multiplying the number of Parent Cash Election Shares covered by such
          Form of Election by a fraction, (A) the numerator of which is the
          Parent Cash Number less the sum of the number of Parent Deminimis
          Shares and Parent Non-Prorated Cash Shares and (B) the denominator of
          which is the aggregate number of Parent Cash Election Shares less the
          sum of the number of Parent Deminimis Shares and Parent Non-Prorated
          Cash Shares, rounded down to the nearest whole number; provided
          further, however, that, if the number of Parent Non-Prorated Cash
          Shares exceeds the difference between the Parent Cash Number and the
          number of Parent Deminimis Shares, the Parent Non-Prorated Cash Shares
          will be converted into the Parent Cash Consideration by selecting, by
          lottery or such other method as mutually agreed to by Parent and the
          Company, from among the record holders of Parent Non-Prorated Cash
          Shares a sufficient number of such holders (the "Parent Cash
          Designees") such that the number of Parent Cash Election Shares held
          by the Parent Cash Designees will, when added to the Parent Deminimis
          Shares, be equal as closely as practicable to the Parent Cash Number,
          and all such Parent Cash Election
<PAGE>

                                                                               9

          Shares held by such Parent Cash Designees will be converted into the
          right to receive the Parent Cash Consideration; and

               (C) all Parent Cash Election Shares not converted into Parent
          Cash Consideration in accordance with Section 2.01(a)(v)(A) or (B)
          will be converted into the right to receive the Parent Stock
          Consideration.

          (vi) Allocation of Parent Stock Election Shares. In the event that the
     aggregate number of Parent Stock Election Shares exceeds the Parent Stock
     Number, all Parent Cash Election Shares and all Parent Non-Election Shares
     (together, the "Parent Cash Shares") will be converted into the right to
     receive the Parent Cash Consideration, and all Parent Stock Election Shares
     will be converted into the right to receive the Parent Cash Consideration
     or the Parent Stock Consideration in the following manner:

               (A) the number of Parent Stock Election Shares covered by each
          Form of Election to be converted into Parent Cash Consideration will
          be determined by multiplying the number of Parent Stock Election
          Shares covered by such Form of Election by a fraction, (1) the
          numerator of which is the Parent Cash Number less the number of Parent
          Cash Shares and (2) the denominator of which is the aggregate number
          of Parent Stock Election Shares, rounded down to the nearest whole
          number; and

               (B) all Parent Stock Election Shares not converted into Parent
          Cash Consideration in accordance with Section 2.01(a)(vi)(A) will be
          converted into the right to receive the Parent Stock Consideration.

          (vii)  No Allocation.  In the event that neither Section 2.01(a)(v)
     nor Section 2.01(a)(vi) is applicable, all Parent Cash Election Shares and
     deemed Parent Cash Election Shares will be converted into the right to
     receive the Parent Cash Consideration, all Parent Stock Election Shares
     will be converted into the right to receive the Parent Stock Consideration,
     a number of Parent Non-Election Shares (as hereinafter defined) equal to
     the Parent Cash Number minus the sum of Parent Cash Election Shares and
     Parent Deminimis
<PAGE>

                                                                              10



     Shares will be converted into the right to receive the Parent Cash
     Consideration and a number of Parent Non-Election Shares equal to the
     Parent Stock Number minus Parent Stock Election Shares will be converted
     into the right to receive the Parent Stock Consideration. "Parent Non-
     Election Shares" means, collectively, shares of Parent Common Stock in
     respect of which a Parent Non-Election is made or as to which no election
     is made, other than Parent Deminimis Shares.

          (viii)  Computations.  The Exchange Agent (as defined in Section
     2.02(c)) consultation with Parent and the Company, will make all
     computations to give effect to this Section 2.01(a).

          (ix)  Parent Preferred Stock.  The Parent Preferred Stock (as defined
     in Section 4.03(a)) outstanding immediately prior to the Exchange Effective
     Time shall remain outstanding, without change, after the Exchange Effective
     Time, and no consideration shall be delivered or deliverable in exchange
     therefor.

          (x)  Dissent Rights.  Notwithstanding anything in this Agreement to
     the contrary, shares ("Parent Dissent Shares") of Parent Common Stock that
     are outstanding immediately prior to the Exchange Effective Time and that
     are held by any person who is entitled to demand and properly demands
     payment of the fair value of such Parent Dissent Shares pursuant to, and
     who complies in all respects with, Subchapter D of Chapter 15 of the PBCL
     ("Subchapter D") shall not be converted into Exchange Consideration as
     provided in Section 2.01(a)(ii), but rather the holders of Parent Dissent
     Shares shall be entitled to payment of the fair value of such Parent
     Dissent Shares in accordance with Subchapter D; provided, however, that if
     any such holder shall fail to perfect or otherwise shall waive, withdraw or
     lose the right to receive payment of fair market value under Subchapter D,
     then the right of such holder to be paid the fair value of such holder's
     Parent Dissent Shares shall cease and such Parent Dissent Shares shall be
     deemed to have been converted as of the Exchange Effective Time into, and
     to have become exchangeable solely for the right to receive, Exchange
     Consideration as provided in Section 2.01(a)(ii).

     shall cease to exist, and no Newco Common Stock or other consideration
     shall be delivered or deliverable in exchange therefor.

     Stock shall be converted into the right to receive either (1) $42.75 in
     cash (the "Company Cash Consideration") or (2) 0.95 (the "Company

     Stock (the "Company Exchange Ratio"), in each case as the holder thereof
     shall have elected or be deemed to have elected, in accordance with Section
     2.01(b)(iv).

     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

     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

                                                                              16



     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
sum of the total aggregate Parent Cash Consideration and 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
equal to the sum of the total aggregate Parent Cash Consideration and 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 in accordance with Section 2.02(e).

          (b)  Exchange Procedures.  (i)  Not more than 90 days nor fewer than
30 days prior to the Closing Date, the Exchange Agent will mail a form of
election (a "Form of Election") to holders of record of shares of Parent Common
Stock and to the holders of record of shares of Company Common Stock (as of a
record date as close as practicable to the date of mailing and mutually agreed
to by Parent and Company).  In addition, the Exchange Agent will use its best
efforts to make the Form of Election available to all persons who become
shareholders of Parent or Company during the period between such record date and
the Closing Date. Any election to receive the Exchange Consideration
contemplated by Section 2.01(a)(iv) or the Merger Consideration contemplated by
Section 2.01(b)(iv) will have been properly made only if the Exchange Agent
shall have received at its designated office or offices, by 5:00 p.m., New York
City time, on the fifth business day immediately
<PAGE>

                                                                              17


preceding the Closing Date or such other date as may be agreed to by Parent and
the Company (the "Election Deadline"), a Form of Election properly completed and
accompanied by a Parent Certificate (as hereinafter defined) or a Company
Certificate (as hereinafter defined), as the case may be for the shares to which
such Form of Election relates, duly endorsed in blank or otherwise acceptable
for transfer on the books of Parent or Company, as the case may be (or an
appropriate guarantee of delivery), as set forth in such Form of Election. An
election may be revoked only by written notice received by the Exchange Agent
prior to 5:00 p.m., New York City time, on the Election Deadline. A revoked
election cannot be reinstated without valid resubmission, by the Election
Deadline of a valid Election Form, and a revocation will not constitute an
election for any other consideration. Revoked elections can only be replaced by
a new Form of Election properly completed and accompanied by the applicable
Parent Certificate or a Company Certificate, duly endorsed in blank or otherwise
acceptable for transfer in accordance with the previous sentence that is
received by the Exchange Agent by the Election Deadline. All elections shall
automatically be revoked if the Exchange Agent is notified in writing by Parent
and Company that either of the First Step Exchange or the Second Step Merger has
been abandoned. If an election is so revoked, the Certificate(s) (as hereinafter
defined) (or guarantee of delivery, as appropriate) to which such election
relates will be promptly returned to the person submitting the same to the
Exchange Agent. In the case of multiple Forms of Elections are received by the
Exchange Agent in respect of the same share of Company Common Stock or Parent
Common Stock, as the case may be, the last dated (or if not dated, the last
received) will govern.

          (ii)  Two or more holders of Parent Common Stock or Company Common
Stock who are determined to constructively own the shares of Parent Common Stock
or Company Common Stock, as the case may be, owned by each other by virtue of
Section 318(a) of the Code, and who so certify to Parent's and Company's
satisfaction, and any single holder of shares of Parent Common Stock or Company
Common Stock who holds his shares in two or more different names and who so
certifies to Parent's and Company's satisfaction, may submit a joint Form of
Election covering the aggregate shares of Parent Common Stock or Company Common
Stock, as the case may be, owned by all such holders or by such single holder,
as the case may be.  For all purposes of this Agreement, each such group of
holders that, and each such single holder who,
<PAGE>

                                                                              18


submits a joint Form of Election shall be treated as a single holder of Parent
Common Stock or Company Common Stock, as the case may be.

          (iii)  Record holders of Parent Common Stock or Company Common Stock
who are nominees only may submit a separate Form of Election for each beneficial
owner for whom such record holder is a nominee; provided, however, that on the
request of Parent or Company, such record holder shall certify to the
satisfaction of Parent or Company that such record holder holds such Parent
Common Stock or Company Common Stock, as the case may be, as nominee for the
beneficial owner thereof.  For purposes of this Agreement, each beneficial owner
for which a Form of Election is submitted will be treated as a separate holder
of Parent Common Stock or Company Common Stock, as the case may be, subject,
however, to the immediately preceding sub-paragraph (ii) dealing with joint
Forms of Election and the immediately following sub-paragraph (iii) dealing with
dividend reinvestment plans.

          (iv)  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 or Parent Common Stock for the purposes of Section 2.02(e).

          (v)  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.
<PAGE>

                                                                              19




          (vi)  With respect to properly made elections in accordance with
Section 2.02(b)(i), upon surrender of a 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
Parent Cash Consideration or 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 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) or Subchapter D of Chapter 15 of
the PBCL (in the case of Parent Certificates) 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.

          (c)  Distributions with Respect to Unexchanged Shares.  No dividends
or other distributions with respect to
<PAGE>

                                                                              20


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 surrender payable with
respect to such whole shares of Newco Common Stock.

          (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
<PAGE>

                                                                              21


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)  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 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
<PAGE>

                                                                              22


Section 2.01(b)(ii) (or would be entitled but for this Section 2.02(e)) and the
denominator of which is the aggregate 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.

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

                                                                              23


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

          (j)  Determination of Proper Elections.  Without limiting the
generality or effect of any other provision hereof, the Exchange Agent will have
discretion to determine whether or not elections have been properly made or
revoked pursuant to this Article II with respect to Parent Common Stock or
Company Common Stock and when elections and revocations were received by it.  If
the Exchange Agent determines that any election was not properly made with
respect to Parent Company Stock or Company Common Stock, such Parent Company
Stock or Company Common Stock will be treated by the Exchange Agent as, and for
all purposes of this Agreement will be deemed to be, Parent Non-Election Shares
or Company Non-Election Shares, as the case may be, at the Exchange Effective
Time or the Merger Effective Time, as the case may be.  The Exchange Agent will
also make computations as to the allocation and proration contemplated by this
Article II and any such computation will be conclusive and binding.  The
Exchange Agent may, with the mutual agreement of Parent and the Company, make
such equitable changes in the procedures set forth herein for the implementation
of the elections provided for in this Article II as it determines to be
necessary or desirable to effect fully such elections.

          Section 2.03.  Certain Adjustments.  (a)  Parent and the Company may,
upon mutual agreement, and in order to prevent the failure of the closing
conditions set forth in
<PAGE>

                                                                              24


Section 7.02(d) and 7.03(d) or to ensure that the Merger and the other
Transactions are treated as a purchase of the Company by Parent under GAAP,
change the Parent Cash Number and the Parent Stock Number and the Company Cash
Number and the Company Stock Number (the "Reallocation") so long as the sum of
the (i) product of the Parent Cash Number and the Parent Cash Consideration and
(ii) the product of the Company Cash Number and the Company Cash Consideration,
does not change as a result of the Reallocation.

          (b)  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 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),
<PAGE>

                                                                              26


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.

          SECTION 3.03.  Capital Structure.  (a)  The authorized capital stock
of the Company consists of 400,000,000 shares of Company Common Stock.  At the

February 2, 1998 (as amended from time to time, the "Company Rights Agreement"),
between the Company and First Chicago Trust Company of New York, as Rights
Agent.

          (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
shares of capital stock or other voting securities of the Company were issued,
reserved for issuance or outstanding.

          (c)  All outstanding shares of Company Common Stock are, and all such
shares that may be issued prior to the Merger Effective Time will be when
issued, duly authorized, validly issued, fully paid and nonassessable and not
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
options, warrants, rights, convertible or exchangeable securities, "phantom"
stock rights, stock appreciation rights, stock-based performance units,
commitments, Contracts, arrangements or undertakings of any kind to which the
Company or any Company 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 any Company Subsidiary to issue, grant, extend or enter into any such
option, warrant, call, right, security, commitment, Contract, arrangement or
undertaking.

          (f)  As of the date of this Agreement, except as described in the
Company Disclosure Letter, there are not

                                                                              28



any outstanding contractual obligations of the Company or any Company Subsidiary
to repurchase, redeem or otherwise acquire any shares of capital stock of the
Company or any Company Subsidiary.

          (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 takeover statute or similar statute or
regulation applies or purports to apply 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
<PAGE>

                                                                              29




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
of the properties or assets of the Company or any Company Subsidiary under, 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,
permit, concession, franchise or other instrument (a "Contract") to which the
Company or any Company 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 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
aggregate, have not had and could not reasonably be expected to have a Company
Material Adverse Effect.

          (b)  No consent, approval, license, permit, order or authorization
(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) ("Consent") of, action by or in respect of, or
registration, declaration or filing with, or notice to, any Federal, state,
local or foreign government or any court of competent jurisdiction,

administrative or regulatory agency or commission or other governmental
authority or instrumentality or any non-governmental self-regulatory agency,
commission or authority, domestic or foreign (a "Governmental Entity") is
required to be obtained or made by or with respect to the Company or any Company
Subsidiary in connection with the execution, delivery and performance of this
Agreement or the consummation of the Transactions, other than (i) compliance

(collectively, whether or not legally required to be obtained, the "Company
Required Statutory Approvals").

          (c)  The Company and the Company Board have taken all action necessary
to (i) render the Company Rights inapplicable to this Agreement, the Merger and
the other Transactions and (ii) ensure that (A) neither Parent nor any of its
affiliates or associates is or will become an "Acquiring Person" (as defined in
the Company Rights Agreement) by reason of this Agreement, the Merger or any
other Transaction, (B) a "Distribution Date" (as defined in
<PAGE>

                                                                              31



the Company Rights Agreement) shall not occur by reason of this Agreement, the
Merger or any other Transaction and (C) the Company Rights shall expire
immediately prior to the Merger Effective Time.

          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 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,
<PAGE>

                                                                              32



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 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 (as defined in Section 6.01) or the Parent Shareholders Meeting (as
defined in Section 6.01), 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 Proxy Statement will comply as to form in
all material respects with the requirements of the Exchange Act and the rules
and regulations thereunder, except that no representation is made by the Company
with respect to statements made or incorporated by reference therein based on
information supplied by or on behalf of Parent or Newco for inclusion or
incorporation by reference in the Proxy Statement.

          SECTION 3.08.  Absence of Certain Changes or Events.  Except as
disclosed in the Company SEC Documents filed and publicly available prior to the
date of this Agreement (the "Filed Company SEC Documents") or in the Company
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 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
<PAGE>

                                                                              33


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 Company, except insofar
     as may have been required by a change in GAAP.

          SECTION 3.09.  Taxes.  (a)  Each of the Company and each Company
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
<PAGE>

                                                                              34


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, 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>

                                                                              35



          (g)  For purposes of this Agreement:

          "Taxes" includes all forms of taxation, whenever created or imposed,
and whether of the United States or elsewhere, and whether imposed by a local,
municipal, state, foreign, Federal or other Governmental Entity, or in
connection with any agreement with respect to Taxes, including all interest,
penalties and additions imposed with respect to such amounts.

          "Tax Return" means all Federal, state, local, provincial and foreign
Tax returns, declarations, statements, reports, schedules, forms and information
returns and any amended Tax return required to be filed with any taxing
authority with respect to Taxes.

          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 or is obligated to contribute (collectively, "Company
Benefit Plans") or (c) any Company Employment Arrangements (as defined herein).
Except as 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 (collectively, the "Company
Employment Arrangements").

          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
<PAGE>

                                                                              36


Agreement. With respect to each Company Benefit Plan (other than a multiemployer
plan within the meaning of Section 4001(a)(3) of ERISA) and Company Employment
Arrangement, the Company has delivered to Parent true, complete and correct
copies of (i) each such Company Benefit Plan or Company 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 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
intended to be qualified and exempt from Federal income taxes under 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
<PAGE>

                                                                              37


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 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
<PAGE>

                                                                              38



(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 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
<PAGE>

                                                                              39


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

          SECTION 3.14.  Brokers; Schedule of Fees and Expenses.  No broker,
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 the date of this Agreement, 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

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

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, 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

          (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
<PAGE>

                                                                              54

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 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
as set forth in the Parent 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 Parent or any Parent Subsidiary.
Except as set forth in the Parent Disclosure Letter, neither Parent nor any
Parent Subsidiary is bound by any agreement with respect to Taxes.

          (e)  The Parent and each Parent 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 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
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.

          SECTION 4.10.  Absence of Changes in Benefit Plans.  Except as
disclosed in the Parent 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 Parent or any Parent 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 Parent or any Parent Subsidiary or
any beneficiary or dependent thereof, that is sponsored or maintained by Parent
or any Parent Subsidiary or to which Parent or any Parent Subsidiary contributes
or is obligated to contribute (collectively, "Parent Benefit Plans") or (c) any
Parent Employment Arrangements (as defined herein).  Except as disclosed in the
Parent 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 Parent or any Parent Subsidiary
and any current or former employee, officer or director of the Parent or any
Parent Subsidiary (collectively, the "Parent Employment Arrangements").

          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

<PAGE>

                                                                              56



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
relating thereto and (vi) the most recent determination letters issued by the

to be Qualified Plans and letters of recognition of exemption with respect to
any Parent 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 Parent Benefit Plans and Parent Employment
Arrangements, individually and in the aggregate, no event has occurred and, to
the knowledge of 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
<PAGE>

                                                                              57


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 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
<PAGE>

                                                                              58

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 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
as disclosed in the Filed Parent SEC Documents or in the Parent Disclosure
Letter, Parent and Parent Subsidiaries are 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, 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 the date of this Agreement, 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
the status of Parent'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.  Parent has
made available to the Company copies of all correspondence between Parent and
its third party suppliers and vendors concerning their Year 2000 compliance.

          SECTION 4.17.  Environmental Matters. (a)  Compliance.  Except as set

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

          (e)  Assumed and Retained Liabilities.  Except as disclosed in the
Filed Parent SEC Documents or in the Parent Disclosure Letter, none of Parent or
the Parent 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 Parent
Material Adverse Effect.

Subsidiaries is a party to any collective bargaining agreement or other labor
agreement with any union or labor organization and (ii) to the knowledge of
Parent, there is no current union representation question involving employees of

activity or proceeding of any labor organization (or representative thereof) or
employee group to organize any such employees, except to the extent it,
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, or except to
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)
there is no unfair labor practice, employment discrimination or other charge,
claim, suit, action or proceeding against Parent or any of the Parent
Subsidiaries pending, or to the knowledge of Parent, threatened before any
court, governmental department, commission, agency, instrumentality or authority
or any arbitrator and (B) there is no strike, lockout or material dispute,
slowdown or work stoppage pending or, to the knowledge of Parent, threatened
against or involving Parent.

forth in the Filed Parent SEC Documents or in the Parent Disclosure Letter, (a)
the operations of the nuclear generation stations (collectively, the "Parent
Nuclear Facilities") currently or formerly owned, in whole or part, by Parent or

future decommissioning of each Parent Nuclear Facility and the storage and
disposal of spent nuclear fuel.

          (b)  To the best knowledge of Parent, recognizing that AmerGen does
not as of the date of this Agreement, own, or hold any operating licenses for,
nuclear generating stations, (i) the operations of the nuclear generation
stations which are the subject of an existing purchase, operating or similar
agreement by AmerGen or any of its affiliates or assignees (the "AmerGen Nuclear

Except as set forth in the previous sentence, neither Parent nor any "subsidiary

mortgage, indenture, lease, permit, concession, franchise, license or any other
contract, agreement, arrangement or understanding, to which it is a party or by

Company or any Company Subsidiary or otherwise, shall be deemed to be a breach

prior to receipt of the Company Shareholder Approval, and only to the extent

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

     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;

          (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 outstanding 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 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 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

                                                                              89



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.

          (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

                                                                              90



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 soon
as reasonably practicable after the Merger Effective Time, Newco shall file one
or more registration statements on Form S-8 (or any successor or other
appropriate form) with respect to the shares of Newco Common Stock subject to
such Company Employee Stock Options and Parent Employee Stock Options or to such
Stock Plans and shall use its reasonable best efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein
or related thereto) for so long as such Company Employee Stock Options and
Parent Employee Stock Options or such benefits or grants of awards remain
payable or such options remain outstanding. With respect to those individuals
who subsequent to the Merger will be subject to the reporting requirements under
Section 16(a) of the Exchange Act, where applicable, Newco shall administer the
Company Stock Plans and Parent Stock Plans assumed pursuant to this Section 6.04
and the Stock Plans in a manner that complies with Rule 16b-3 of the SEC to the
extent the applicable plan complied with such rule prior to the Merger. Prior to
the Merger Effective Time, Parent and Newco shall take all actions as may be
reasonably required to cause the acquisition of equity securities of Newco, as
contemplated by this Section 6.04, by any person who is or will become a
director or officer of Newco to be eligible for exemption under Rule 16b-3(d) of
the SEC.

     Common Stock granted under any Company Stock Plan.

          "Company Stock Plans" means the Long-Term Incentive Plan of the

          SECTION 6.05.  Benefit Plans; Workforce Matters. (a)  From and after
the Merger Effective Time, Newco and its subsidiaries shall honor and perform in
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 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 and Parent Employment Arrangement in
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),
and Newco shall (i) assume as of the Merger Effective Time each Company Benefit
Plan and Company Employment Arrangement maintained by the Company immediately
prior to the Merger Effective Time and as of the Exchange Effective Time each
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

                                                                              93





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 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
<PAGE>

                                                                              94


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 written request which request shall
include reasonable evidence of the Losses set forth therein) to the extent
arising from, relating to, or otherwise in respect of, any actual or threatened
action, suit, proceeding or investigation, in respect of actions or omissions
occurring at or prior to the Merger Effective Time in connection with such
Indemnified Party's duties as an officer, director or employee as aforesaid, in
each case, of the Company or Parent or any of their respective subsidiaries,
including in respect of this Agreement, the Merger and the other Transactions.

          SECTION 6.07.  Fees and Expenses.  (a)  Except as provided below, all

such definitive agreement or, if earlier, consummation of such transaction or
another transaction with the same party or its affiliates).

          (b)  Promptly following the date of execution of this Agreement,

          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.  Company Common Stock Repurchase. 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 the Merger and the other

Transactions are treated as a purchase of
the Company by Parent under GAAP (in any such determination taking into account
the number of shares of Parent Common Stock in respect of which a notice of
intention to dissent was filed with Parent in accordance with the PBCL).

          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

representations and warranties of the Company shall be deemed not qualified by

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

          (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

          consummation of the Merger;

               (ii) if any Governmental Entity issues an order, decree or ruling

          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

          the Parent Shareholder Approval, the Parent Shareholder Approval is

          (c) by Parent, if the Company breaches or fails to perform in 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
     withdraws or modifies, or publicly proposes to withdraw or modify, in a
     manner adverse to Parent or Newco, its approval or recommendation of this
     Agreement or the Transactions or approves or recommends, or publicly
     proposes to approve or recommend, any Company Competing Transaction or (ii)
     the Company otherwise breaches, or is deemed to be in breach of, any of its
     covenants in Section 5.02 in any material 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,

     in order to comply with its fiduciary obligations under Applicable Law,

     described in clause (ii) above, (iv) at least ten business days following
     receipt by Parent of the notice referred to in clause (iii) above, and
     taking into account any proposal made by Parent since receipt of such

     breaches, or is deemed to be in breach of, any of its covenants in Section

          (h)  by Parent, if prior to receipt of the Parent Shareholder
     Approval, (i) Parent has received a proposal for a Parent Competing
     Transaction that constitutes a Qualifying Parent Proposal that was not
     solicited or encouraged by Parent or its Representatives and that did not
     otherwise result from the breach or a deemed breach of the Section 5.03,

Section 8.02 and Article IX, which provisions shall survive such termination,
and except to the extent that such termination results from the wilful breach by

in which case such termination shall not relieve any party of any liability or
damages resulting from its wilful breach of this Agreement (including any such
case in which a fee is payable by such party pursuant to Section 6.07(b) or (c),

section relates.

          SECTION 9.05.  Severability.  If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule or
Applicable Law, or public policy, all other conditions and provisions of this
Agreement shall nevertheless remain in full force and effect so long as the
economic or legal substance of the transactions contemplated hereby is not
affected in any manner materially adverse to any party.  Upon such determination
that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner to the end that transactions contemplated
hereby are fulfilled to the extent possible.

          SECTION 9.06.  Counterparts.  This Agreement may be executed in one or

each of the parties and delivered to the other parties.

          SECTION 9.07.  Entire Agreement; No Third-Party Beneficiaries.  This
Agreement, taken together with the Company Disclosure Letter, the Parent
Disclosure Letter and the Confidentiality Agreement, (a) constitute the entire
agreement, and supersede all prior agreements and understandings, both written
and oral, among the parties with respect to the Transactions and (b) except for
the provisions of Article II and Sections 6.06, 6.16 and 6.17 are not intended
to confer upon any person other than the parties any rights or remedies.

          SECTION 9.08.  Governing Law.  This Agreement shall be governed by,
and construed in accordance with, the laws of the State of New York, regardless
of the laws that might otherwise govern under applicable principles of conflicts

          SECTION 9.09.  Assignment.  Neither this Agreement nor any of the
rights, interests or obligations under this Agreement shall be assigned, in
whole or in part, by operation of law or otherwise by any of the parties without
the prior written consent of the other parties, except that Newco may assign, in
its sole discretion, any of or all its rights, interests and obligations under
this Agreement to Parent or to any direct or indirect wholly owned subsidiary of
Parent, but no such assignment shall relieve Newco of any of its obligations
under this Agreement. Any purported assignment without such consent shall be

successors and assigns.

by motion or other request for leave from any such court, (c) agrees that it
will not bring any action relating to this Agreement or any Transaction in any
court other than any New York state court or any Federal court sitting in the

                        Form of Company Affiliate Letter
                        --------------------------------

Dear Sirs:

          The undersigned refers to the Agreement and Plan of Exchange and
Merger (the "Merger Agreement") dated as of September 22, 1999, among PECO
Energy Company, a Pennsylvania corporation, PECO Energy 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 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 much transaction is registered
under the 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>

                                                                               3


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

                        Form of Parent Affiliate Letter
                        -------------------------------


Dear Sirs:

          The undersigned refers to the Agreement and Plan of Exchange and
Merger (the "Merger Agreement") dated as of September 22, 1999, among PECO
Energy Company, a Pennsylvania corporation, PECO Energy 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 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 much transaction is registered
under the 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.


                                       Very truly yours,



Dated:

          On                 , the undersigned sold the securities of NEW HOLDCO

Ladies and Gentlemen:

          In connection with the opinions to be delivered pursuant to Sections
7.02(d) and 7.03(d) of the Agreement and Plan of Exchange and Merger (the
"Exchange and Merger Agreement") dated as of September 22, 1999, among PECO
ENERGY COMPANY, a Pennsylvania corporation ("Parent"), PECO ENERGY 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.  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") or cash is the result
of arm's length bargaining.  The aggregate fair market value of the Newco Common
Stock and/or cash 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 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
<PAGE>

                                                                               3


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.

          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
<PAGE>

                                                                               4


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.


                                       Very truly yours,

Ladies and Gentlemen:

          In connection with the opinions to be delivered pursuant to Sections
7.02(d) and 7.03(d) of the Agreement and Plan of Exchange and Merger (the
"Exchange and Merger Agreement") dated as of September 22, 1999, among PECO
ENERGY COMPANY, a Pennsylvania corporation ("Parent"), PECO ENERGY 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 facts
relate to Newco, true, correct and complete in all material respects.
<PAGE>

                                                                               2


          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") or cash 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 or cash are
the result of arm's length bargaining.  The aggregate fair market value of the
Newco Common Stock and/or cash to be received by holders of Parent Common Stock
and Company Common Stock in the Merger will be approximately equal to the fair
market value of the Parent Common Stock or the Company Common Stock, as the case
may be, surrendered in exchange therefor.

          3.  Cash payments 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).

          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).
<PAGE>

                                                                               3


          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).

          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 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.

                                                                               5


          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

                          [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 Agreement and Plan of Exchange and Merger (the
"Exchange and Merger Agreement") dated as of September 22, 1999, among PECO
ENERGY COMPANY, a Pennsylvania corporation ("Parent"), PECO ENERGY 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
<PAGE>

Registration Statement are, insofar as such 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") or cash is the result
of arm's length bargaining. The aggregate fair market value of the Newco Common
Stock and/or 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 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.

          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.

                                                                               3


          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
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
<PAGE>

                                                                               4


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.

          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

                                                                               5


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

Merger (the "Merger Agreement") pursuant to which, among other things, the

shares of common stock of Newco, subject to the terms and conditions of the
Merger Agreement;

          WHEREAS, the Company and the Rights Agent desire to amend the Rights
Agreement to render the Rights inapplicable to the Merger and the other

          NOW, THEREFORE, in consideration of the foregoing and the agreements,
provisions and covenants herein contained, the parties agree as follows:

     1.   Section 1 of the Rights Agreement is hereby amended by adding a new

     Agreement) or the consummation of the other transactions contemplated by
     the Merger Agreement including the Transactions (as defined in the Merger
     Agreement)."

     3.   Section 7(a) of the Rights Agreement is hereby amended by deleting
