issuance by Newco of Newco Common Stock in connection with the Merger (the

parties) of the conditions set forth in Section 7.01, or, if on such day any

Applicable Law and as Parent and the Company shall have agreed prior to the
Merger Effective Time, be the Articles of Incorporation of the Surviving
Corporation and shall in any case be amended to provide that the name of Newco
be changed to such name as shall be mutually agreed to by Parent and the
Company.

                  (b) At the Merger Effective Time, the By-laws of Newco (the

                                                                               6

                       Effect on the Capital Stock of the
               Constituent Corporations; Exchange of Certificates

                  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
         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.

                                                                               7

                  (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 (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.

                                                                               8

                  (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;

                           (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  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

                                                                              10

         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 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).

                  (b) Second Step Merger. At the Merger Effective Time, by
virtue of the Second Step Merger and without any action on the part of the
holder of any shares of Company Common Stock or Newco Common Stock:

                  (i) Cancelation of Treasury Stock and Newco- Owned Stock. Each
         share of Company Common Stock that is owned by the Company or Newco
         shall no longer be outstanding and shall automatically be canceled and
         retired and shall cease to exist, and no Newco Common Stock or other
         consideration shall be delivered or deliverable in exchange therefor.

                                                                              12

                  (ii) Conversion of Company Common Stock. (A) Subject to
         Sections 2.01(b)(i), 2.01(b)(iii) and 2.02(e), each issued share of
         Company Common 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 Conversion Number") fully paid and nonassessable
         shares of Newco Common 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).

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

                  (iii) Allocation. Notwithstanding anything in this Agreement
         to the contrary, the number of shares of the Company Common Stock to be
         converted into the right to receive the Company Cash Consideration in
         the Second Step Merger (the "Company Cash Number") will be equal to
         17,543,859 shares of the Company Common Stock. The number of shares of
         the Company Common Stock to be converted into the right to receive the
         Company Stock Consideration in the Second Step Merger (the "Company
         Stock Number") will be equal to (A) the number of shares of the Company
         Common Stock issued and outstanding immediately prior to the Merger
         Effective Time (ignoring for this purpose any Company Common Stock to
         be canceled pursuant to Section 2.01(b)(i)) less (B) the Company Cash
         Number.

                                                                              13

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

                  (v) Allocation of the Company Cash Election Shares. In the
         event that the aggregate number of shares in respect of which the
         Company 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(b)(iv) (the "Company Cash Election Shares") exceeds the
         Company Cash Number, all shares of the Company Common Stock in respect
         of which the Company Stock Elections have been made (the "Company Stock
         Election Shares") and all the Company Non-Election Shares (as defined
         in Section 2.01(b)(vii)) will be converted into the right to receive
         the Company Stock Consideration (and cash in lieu of fractional
         interests in accordance with


<PAGE>

                                                                              14

         Section 2.02(e)), and the Company Cash Election Shares will be
         converted into the right to receive the Company Cash Consideration or
         the Company Stock Consideration in the following manner:

                  (A) all the Company Deminimis Shares will be converted into
         the right to receive the Company Cash Consideration;

                  (B) the number of the Company Cash Election Shares, other than
         the Company Deminimis Shares, covered by each Form of Election to be
         converted into the Company Cash Consideration will be determined by
         multiplying the number of the Company Cash Election Shares covered by
         such Form of Election by a fraction, (A) the numerator of which is the
         Company Cash Number less the number of the Company Deminimis Shares and
         (B) the denominator of which is the aggregate number of the Company
         Cash Election Shares less the number of the Company Deminimis Shares,
         rounded down to the nearest whole number; provided, however, that, if
         as a result of such proration, any holder of the Company Cash Election
         Shares would, but for this proviso, receive less than 100 shares of
         Newco Common Stock in accordance with Section 2.01(b)(v)(C), all the
         Company Cash Election Shares held by such holders (the "Company
         Non-Prorated Cash Shares") will be converted into the
         Company Cash Consideration and the remaining the Company Cash Election
         Shares to be converted into the Company Cash Consideration will be
         determined by multiplying the number of the Company Cash Election
         Shares covered by such Form of Election by a fraction, (A) the
         numerator of which is the Company Cash Number less the sum of the
         number of the Company Deminimis Shares and the Company Non-Prorated
         Cash Shares and (B) the denominator of which is the aggregate number of
         the Company Cash Election Shares less the sum of the number of the
         Company Deminimis Shares and the Company Non-Prorated Cash Shares,
         rounded down to the nearest whole number; provided further, however,
         that, if the number of the Company Non-Prorated Cash Shares exceeds the
         difference between the Company Cash Number and the number of the
         Company Deminimis Shares, the Company Non-Prorated Cash Shares will be
         converted into the

                                                                              15


         Company 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 the Company Non-Prorated Cash Shares a sufficient
         number of such holders (the "Company Cash Designees") such that the
         number of the Company Cash Election Shares held by the Company Cash
         Designees will, when added to the Company Deminimis Shares, be equal as
         closely as practicable to the Company Cash Number, and all such the
         Company Cash Election Shares held by such the Company Cash Designees
         will be converted into the right to receive the Company Cash
         Consideration; and

                  (C) all Company Cash Election Shares not converted into the
         Company Cash Consideration in accordance with Section 2.01(b)(v)(A) or
         (B) will be converted into the right to receive the Company Stock
         Consideration (and cash in lieu of fractional interests in accordance
         with Section 2.02(e)).

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

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

                  (B) all the Company Stock Election Shares not converted into



<PAGE>
                                                                              16


         the Company Cash Consideration in accordance with Section
         2.01(b)(vi)(A) will be converted into the right to receive the Company
         Stock Consideration (and cash in lieu of fractional interests in
         accordance with Section 2.02(e)).

                  (vii) No Allocation. In the event that neither Section
         2.01(b)(v) nor Section 2.01(b)(vi) is applicable, all the Company Cash
         Election Shares and deemed Company Cash Election Shares shall be
         converted into the right to receive the Company Cash Consideration, all
         the Company Stock Election Shares shall be converted into the right to
         receive the Company Stock Consideration (and cash in lieu of fractional
         interests in accordance with Section 2.02(e)), a number of Company
         Non-Election Shares (as hereinafter defined) equal to the Company Cash
         Number minus the sum of Company Cash Election Shares and Company
         Deminimis Shares will be converted into the right to receive the
         Company Cash Consideration and a number of Company Non-Election Shares
         equal to the Company Stock Number minus Company Stock Election Shares
         will be converted into the right to receive the Company Stock
         Consideration (and cash in lieu of fractional interests in accordance
         with Section 2.02(e)). "Company Non-Election Shares" means,
         collectively, shares of Company Common Stock in respect of which a
         Company Non-Election is made or as to which no election is made, other
         than Company Deminimis Shares.

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

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

                  (x) Dissent Rights. Notwithstanding anything in this Agreement
         to the contrary, shares ("Company

                                                                              17

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

                  SECTION 2.02. Exchange of Certificates. (a) Exchange Agent.
Promptly following the Merger Effective Time, Newco shall deposit with such bank
or trust company as may be designated by Newco and reasonably acceptable to
Parent and the Company (the "Exchange Agent"), for the benefit of the holders of
shares of Parent Common Stock and Company Common Stock, for exchange in
accordance with this Article II, through the Exchange Agent, cash equal to the
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


<PAGE>

                                                                              18

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 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.

                                                                              19

                  (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, 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


<PAGE>
                                                                              20


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.

                  (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


<PAGE>

                                                                              21

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 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


<PAGE>

                                                                              22

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 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


<PAGE>
                                                                              23

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 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.


<PAGE>
                                                                              24


                  (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, 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


<PAGE>

                                                                              25

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 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

<PAGE>
                                                                              26

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


<PAGE>

                                                                              27

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

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

                  (b) Except for its interests in the Company


<PAGE>
                                                                              28


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

                  (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

when issued, duly


<PAGE>
                                                                              29


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

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)

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 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.

                                                                              30


                  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 not necessary to consummate any Transaction other than
the Second Step Merger.

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

                  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


<PAGE>
                                                                              34


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, 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


<PAGE>
                                                                              35


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 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


<PAGE>
                                                                              36

any failure to pay, individually or in the aggregate, has not had and could not
reasonably be expected to have a Company Material Adverse Effect.

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


<PAGE>
                                                                              37

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.

                  (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

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,

The Company Disclosure Letter includes a complete list of all material Company
Benefit Plans and Company Employment Arrangements as of the date of this

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

<PAGE>
                                                                              39

trust that is intended to meet the requirements of Section 501(c)(9) of the
Code.

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

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


<PAGE>
                                                                              40

(other than routine claims for benefits).

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

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

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

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

                  (h) Except as disclosed in the Company Disclosure


<PAGE>

                                                                              41

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
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


<PAGE>
                                                                              42

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 copy of which opinion has been delivered to Parent.

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

                  SECTION 3.17. Environmental Matters. (a) Compliance. Except as
set forth in the Filed Company SEC Documents or in the Company Disclosure
Letter, the Company and each of the Company Subsidiaries is and has been in



<PAGE>
                                                                              43

compliance with all applicable Environmental Laws (as defined below), except

obligation, enforceable against it in accordance with its terms.

                  (b) The Board of Directors of Parent (the "Parent Board"), at

affirmative vote of a majority of the votes cast by all holders of Parent Common

(with or without notice or lapse of time, or both) under, or give rise to a
right of termination, consent, approval, cancelation or

increased, additional, accelerated or guaranteed rights or entitlements of any
person under, or result in the creation of any Lien upon any of the properties
or assets of Parent or any Parent Subsidiary under, any provision of (i) Parent
Charter, Parent By-laws or the comparable charter or organizational documents of
any Parent Subsidiary, (ii) any Contract to which Parent or any Parent
Subsidiary is a party or by which any of their respective properties or assets
is bound or (iii) subject to the filings and other matters referred to in
Section 4.05(b), any Judgment or Applicable Law or writ, permit or license

any such items that, individually or in the aggregate, have not had and could
not reasonably be expected to have a Parent Material Adverse Effect.

registration, declaration or filing with, or notice to, any Governmental Entity

Public Utility Commission (the "PPUC"), (vii) the consents, filings and
approvals required under PUHCA, (viii) compliance with and such filings as may
be required under applicable Environmental Laws, (ix) such filings as may be

other items as are set forth in the Parent Disclosure Letter (collectively,

Approvals").

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

course of business in substantially the same manner as previously conducted and
not prohibited by this Agreement, 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

                                                                              57

                  (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 Subsidiary, have been timely paid, except to the extent that any failure
to pay, individually or in the aggregate, has

                                                                              58

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

                                                                              59

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").

<PAGE>
                                                                              60

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

                                                                              61

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

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


<PAGE>
                                                                              62

and nothing has occurred since the date of such letter that could reasonably be
expected to affect the qualified status of such Parent Benefit Plan.

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

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

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

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

                  SECTION 4.13. Compliance with Applicable Laws; Permits. (a)
Except as disclosed in the Filed Parent SEC


<PAGE>
                                                                              63

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.

                                                                              64

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 forth in the Filed Parent SEC Documents or in the Parent Disclosure Letter,
Parent and each of the Parent Subsidiaries is and has been in compliance with
all applicable Environmental Laws, except where the failure to so comply,
individually or in the aggregate, has not had and could not reasonably be
expected to have a Parent Material Adverse Effect.

                  (b) Environmental Permits. Except as set forth in the Filed
Parent SEC Documents or in the Parent Disclosure Letter, (i) Parent and each of
the 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

<PAGE>
                                                                              65

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.

                  SECTION 4.18. Labor and Employee Relations. (a) Except as set
forth in the Parent Disclosure Letter, (i) neither Parent nor any of the Parent
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
Parent or any of the Parent Subsidiaries, nor does Parent have knowledge of any
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

(A) there is no unfair labor practice, employment discrimination or

as set 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

current 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

warranties contained in Sections 4.05(a), 4.05(b), 4.12, 4.13 and 4.17 with
respect to AmerGen, as if AmerGen were a Parent Subsidiary as defined in this
Agreement, it being understood that the Company acknowledges and agrees that as

or warranty is made concerning AmerGen or its business or operations except as

be expected to constitute a breach of the fiduciary obligations of such Board of
Directors under Applicable Law, in response to a proposal for a Company
Competing Transaction that constitutes a Qualifying Company Proposal (as defined

5.02(a) by any Representative or affiliate of the Company or any Company

Company from taking and disclosing to its shareholders a position contemplated
by Rule 14e-2(a) promulgated under the Exchange Act or from making any
disclosure to its shareholders if, in the good faith

of the Transactions) and to be more favorable generally to the Company's
shareholders than the Transactions (taking into account all financial and

                  (h) Parent, as sole shareholder of Newco, shall adopt this
Agreement.

subsidiaries to, furnish promptly to the other party (a) a copy of each report,
schedule, registration statement and other document filed by it during such
period pursuant to the requirements of Federal or state securities laws and (b)
all other information concerning its business, properties and personnel as such
other party may reasonably request. Without limiting the generality of the
foregoing, each of the Company and Parent shall, within two business days of
request therefor, provide to the other the information (x) described in Rule

Stock would be entitled under Section 7.75 of the IBCA (assuming such holder met
the requirements of such Section) and (z) to which a holder of Parent Common
Stock would be entitled under Section 1508 of the PBCL (assuming such holder met
the requirements of such Section). All information exchanged pursuant to this
Section 6.02 shall be subject to the confidentiality agreement dated July 15,
1999, between the Company and Parent (the "Confidentiality Agreement"), and this
Agreement constitutes a Definitive Agreement as defined therein.

                  SECTION 6.03. Regulatory Matters; Reasonable Best Efforts. (a)
Regulatory Approvals. Upon the terms and subject to the conditions set forth in
this Agreement, and subject to actions taken in compliance with Section 5.02(b)
or 5.03(b), as the case may be, each of the parties hereto shall cooperate and
promptly prepare and file all necessary documentation, to effect all necessary
applications, notices, petitions, filings and other documents, and shall use
reasonable best efforts to obtain all necessary Consents of all Governmental
Entities necessary or advisable to consummate and make effective, in the most
expeditious manner practicable, the Merger and the other Transactions, including
the Parent Required Statutory Approvals and the Company Required Statutory
Approvals. Parent shall have the right to review and approve in advance all
characterizations of the information relating to the Company, on the one hand,
and the Company shall have the right to review and approve in advance all
characterizations of the information relating to Parent, on the other hand, in
either case, which appear in any filing made in connection with the Merger or
the other Transactions. Parent and the Company agree that they will consult with
each other with respect to the obtaining

                                                                              92

of all such necessary Consents of Governmental Entities.

                  (b) Further Actions. Upon the terms and subject to the
conditions set forth in this Agreement, each of the parties agrees to use
reasonable best efforts to take, or cause to be taken, all actions, and to do,
or cause to be done, and to assist and cooperate with the other parties in
doing, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Merger and the other
Transactions, including (i) the obtaining of all necessary consents, approvals
or waivers from third parties, (ii) the defending of any lawsuits or other legal
proceedings, whether judicial or administrative, challenging this Agreement or
the consummation of the Transactions, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed, and (iii) the execution and delivery of any additional
instruments necessary to consummate the Transactions and to fully carry out the
purposes of this Agreement. Notwithstanding the foregoing, the Company and its
Representatives and Parent and its Representatives shall not be prohibited under
this Section 6.03(b) from taking any actions in compliance with Section 5.02(b)
or 5.03(b), respectively.

                  (c) State Anti-Takeover Statutes. In connection with and
without limiting the generality of Section 6.03(b), Parent and the Company shall
(i) take all action necessary to ensure that no state anti-takeover statute or
similar statute or regulation is or becomes applicable to any Transaction or
this Agreement and (ii) if any state anti-takeover statute or similar statute or
regulation becomes applicable to any Transaction or this Agreement, take all
action necessary to ensure that the Merger and the other Transactions may be
consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise to minimize the effect of such statute or regulation on
the Merger and the other Transactions. Notwithstanding the foregoing, the
Company and its Representatives and Parent and its Representatives shall not be
prohibited under this Section 6.03(c) from taking any action permitted by
Section 5.02(b) or 5.03(b), respectively.

                  (d) Notices. The Company shall give prompt notice to Parent,
and Parent or Newco shall give prompt notice to the Company, of (i) any
representation or warranty made by it contained in this Agreement that is
qualified as to materiality becoming untrue or inaccurate in any respect or any
such representation or warranty that is not so qualified becoming untrue or
inaccurate in any material respect or (ii) the failure by it to comply with or
satisfy in any material respect any covenant, condition or agreement to be
complied with or satisfied by it under this Agreement; provided, however, that
no such notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.

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

                  (i) adjust the terms of all outstanding Company Employee Stock
         Options to provide that, at the Merger Effective Time, each Company
         Employee Stock Option outstanding immediately prior to the Merger
         Effective Time shall be deemed to constitute an option to acquire, on
         the same terms and conditions as were applicable under such Company
         Employee Stock Option, the same number of shares of Newco Common Stock
         as the holder of such Company Employee Stock Option would have been
         entitled to receive pursuant to the Merger had such holder exercised
         such Company Employee Stock Option in full immediately prior to the
         Merger Effective Time, at a price per share equal to (A) the aggregate
         exercise price for the shares of Company Common Stock otherwise
         purchasable pursuant to such Company Employee Stock Option immediately
         prior to the Merger Effective Time (whether or not exercisable) divided
         by (B) the number of shares of Newco Common Stock deemed purchasable
         pursuant to such Company Employee Stock Option; provided, however, that
         in the case of any qualified stock options under Sections 422-424 of
         the Code, the option price, the number of shares purchasable pursuant


<PAGE>
                                                                              94

         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


<PAGE>
                                                                              95

         determined in order to comply with Section 424(a) of the Code;

                  (ii) make such other changes to the Parent Stock Plans and the
         terms of outstanding Parent Employee Stock Options as it deems
         appropriate to give effect to the Merger (subject to the approval of
         the Company, which shall not be unreasonably withheld); and
                  (iii) ensure that, after the Exchange Effective Time, no
         Parent Employee Stock Options may be granted under any Parent Stock
         Plan.

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

                  (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

                                                                              96

in effect on the same terms and conditions (subject to the adjustments required
by this Section 6.04 after giving effect to the Merger). Newco shall comply with
the terms of the Parent Stock Plans and ensure, to the extent required by, and
subject to the provisions of, such Parent Stock Plans, that the Parent Employee
Stock Options that qualified as qualified stock options prior to the Exchange
Effective Time continue to qualify as qualified stock options after the Exchange
Effective Time.

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

                                                                              97

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.

                  (f)  In this Agreement:

                  "Company Employee Stock Option" means any option to purchase
         Company Common Stock granted under any Company Stock Plan.

                  "Company Stock Plans" means the Long-Term Incentive Plan of
         the Company as amended from time to time.

         Long-Term Incentive Plan and the PECO Energy Company 1998 Stock Option
         Plan.

                  "Parent SAR" means any stock appreciation right linked to the
         price of Parent Common Stock and granted under any Parent Stock Plan.

                  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


<PAGE>
                                                                              98

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

<PAGE>
                                                                              99

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 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


<PAGE>
                                                                             100

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 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


<PAGE>
                                                                             101

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 fees and expenses incurred in connection with the Merger and the other
Transactions shall be paid by the party incurring such fees or expenses, whether
or not the Merger is consummated, except that expenses incurred in connection
with filing, printing and mailing the Proxy Statement and the Form S-4 shall be
shared equally by Parent and the Company.

                                                                             102

                  (b) The Company shall pay to Parent a fee of $250,000,000 if:
(i) the Company terminates this Agreement pursuant to Section 8.01(f); (ii)
Parent terminates this Agreement pursuant to Section 8.01(d); or (iii) any
Company Competing Transaction was proposed to the Company or publicly disclosed

         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

         terms of the Transactions, such Qualifying Company Proposal remains a
         Qualifying Company Proposal and the Board of Directors of the Company
         has again made the determination referred to in clause (ii) above, (v)
         the Company is in compliance with Section 5.02, (vi) the Company has

         its covenants in Section 5.03 in any material respect; or

         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, (ii) the Board of Directors of Parent has determined in good

         recommendation of this Agreement and the Transactions, (B) terminate

         described in clause (ii) above, (iv) at least ten business days
         following receipt by the Company of the notice referred to in clause
         (iii) above, and taking into account any proposal made by the Company
         since receipt of such notice to amend or modify the terms of the
         Transactions, such Qualifying Parent Proposal remains a Qualifying
         Parent Proposal and the Board of Directors of Parent has again made the

the last two sentences of Section 6.02, Section 6.07, this 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 a party of any
representation, warranty or covenant set forth in this Agreement, 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), or any
expenses of the other party are reimbursed by such party pursuant to Section
6.07(d) or (e), to the extent any such liability or damage suffered by such
other party exceeds such amounts payable pursuant to Section 6.07(b), (c), (d)

parties at any time before or after receipt of the Company Shareholder Approval
or the Parent Shareholder Approval; provided, however, that after receipt of the
Company Shareholder Approval or the Parent Shareholder Approval, there shall be

shareholders of the Company or Parent without the further approval of such
shareholders. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties.

                  SECTION 8.04. Extension; Waiver. At any time prior to the
Merger Effective Time, the parties may (a) extend the time for the performance

inaccuracies in the representations and warranties contained in this Agreement
or in any document delivered pursuant to this Agreement or (c) subject to the
proviso of Section 8.03, waive compliance with any of the agreements or
conditions contained in this Agreement. Any agreement on the part of a party to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of such rights.

                  SECTION 8.05. Procedure for Termination, Amendment, Extension
or Waiver. A termination of this Agreement pursuant to Section 8.01, an

                             [Letterhead of Parent]

                                                                   [Date]

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):

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


<PAGE>

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

                  3. 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.

                  4. 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.

                  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.

                  6. 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.

                  7. 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).

                  8. 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


<PAGE>
                                                                               4

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).

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

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

                  11. 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.

                  12. 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.

                  13. 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


<PAGE>
                                                                               5

and (ii) at least 80% of the total number of shares of each other class of Newco
Stock.

                  14. 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.

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

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

                  17. 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.

                  18. 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.

                  19. 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

<PAGE>
                                                                               6

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


<PAGE>

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.

                  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).

<PAGE>
                                                                               3

                  5. Newco has not acquired, nor, except as a result of the
First Step Exchange will it acquire, nor has it owned in the past five years,
any Parent Common Stock. Newco has not acquired, nor, except as a result of the
Second Step Merger will it acquire, nor has it owned in the past five years, any
Company Common Stock.
                  6. Newco has no present plan or intention to make any
distributions after the Merger to holders of Newco Common Stock (other than
dividends made in the ordinary course of business).

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

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

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

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

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

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

                                                                               5

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

issue any Newco Common Stock in connection with the Merger in consideration for
services rendered to or for the benefit of Newco or any of its affiliates, or in
consideration for the transfer of any property other than Parent Common Stock or
Company assets.

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

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


<PAGE>


as described in the Registration Statement and the documents referenced in the
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.

                                                                               3

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

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

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

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

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

<PAGE>
                                                                               4

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 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

<PAGE>
                                                                               5

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 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,


<PAGE>
                                                                               6

"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
