conversion, each holder of a certificate formerly representing any such shares
of Union Electric Common Stock shall cease to have any rights with respect
thereto, except the right to receive the shares of Company Common Stock to be
issued in consideration therefor upon surrender of such certificate in
accordance with Section 2.3.

     (iv) No Change in Union Electric Preferred Stock.  Each issued and
outstanding share of Preferred Stock, without par value, of Union Electric (the
"Union Electric Preferred Stock"), other than Union Electric Dissenting Shares,
shall remain outstanding and shall continue to represent one fully paid and non-
assessable share of preferred stock of the surviving corporation with identical
rights (including dividend rates) and designations as were applicable to such
share of Union Electric Preferred Stock immediately prior to the Union Electric
Merger.

          (b)  At the Company Effective Time, by virtue of the Company Merger
and without any action on the part of any holder of any capital stock of CIPSCO
or the Company:

     (i) Cancellation of Certain CIPSCO Stock.  Each share of Common Stock,
without par value, of CIPSCO (the "CIPSCO Common Stock") that is owned by CIPSCO
as treasury

                                      -4-

 
stock, by subsidiaries of CIPSCO or by Union Electric, the Company or any of
their respective subsidiaries shall be cancelled and cease to exist.

     (ii) Cancellation of Certain Company Common Stock.  Each issued and
outstanding share of Company Common Stock that is owned by CIPSCO, Union
Electric or any of their wholly owned subsidiaries immediately prior to the
Company Effective Time shall be cancelled and cease to exist.

     (iii)  Treatment of Certain Company Common Stock.  Each share of Company
Common Stock issued pursuant to Section 2.1(a)(iii) hereof shall remain
outstanding and shall continue to represent one share of Company Common Stock.

     (iv) Conversion of CIPSCO Common Stock.  Each issued and outstanding share
of CIPSCO Common Stock (other than shares cancelled pursuant to Section
2.1(b)(i)) shall be converted into the right to receive 1.03 (the "CIPSCO
Exchange Ratio", and together with the Union Electric Exchange Ratio, the
"Exchange Ratios") fully paid and non-assessable shares of Company Common Stock.
Upon such conversion, each holder of a certificate formerly representing any
such shares of CIPSCO Common Stock shall cease to have any rights with respect
thereto, except the right to receive the shares of Company Common Stock to be
issued in consideration therefor upon the surrender of such certificate in
accordance with Section 2.3.

            Section 2.2  Dissenting Shares.

          (a) Shares of Union Electric Common Stock and Union Electric Preferred
Stock held by any holder entitled to relief as a dissenting shareholder under
Section 351.455 of the MGBCL (the "Union Electric Dissenting Shares") shall not
be converted into the right to receive Company Common Stock or remain
outstanding as preferred stock of the surviving corporation, as the case may be,
in the Union Electric Merger, but shall be converted into such consideration as
may be due with respect to such shares pursuant to the applicable provisions of
the MGBCL, unless and until the right of such holder to receive fair value for
such Union Electric Dissenting Shares terminates in accordance with Section
351.455 of the MGBCL.  If such right is terminated otherwise than by the
purchase of such shares by Union Electric, then such shares shall cease to be
Union Electric Dissenting Shares and shall be converted into and represent the
right to receive Company Common Stock or preferred stock of the surviving
corporation in the Union Electric Merger, as provided in Section 2.1(a).

                                      -5-

 
          (b) Shares of CIPSCO Common Stock held by any holder entitled to
relief as a dissenting shareholder under Section 5/11.65 of the IBCL (the
"CIPSCO Dissenting Shares") shall be converted into the right to receive shares
of Company Common Stock in accordance with Section 2.1(b)(iv) of this Agreement
and shall thereafter be subject to sale or purchase as provided in applicable
provisions of the IBCL.

            Section 2.3  Exchange of Certificates.

          (a)  Deposit with Exchange Agent.  As soon as practicable after the
Effective Time, the Company shall deposit with a bank or trust company mutually
agreeable to CIPSCO and Union Electric (the "Exchange Agent"), certificates
representing shares of Company Common Stock required to effect the exchanges
referred to in Section 2.1, together with cash payable in respect of fractional
shares pursuant to Section 2.3(d).

          (b)  Exchange Procedures.  As soon as practicable after the Effective
Time, the Exchange Agent shall mail to each holder of record of a certificate or
certificates which immediately prior to the Union Electric Effective Time
represented outstanding shares of Union Electric Common Stock or CIPSCO Common
Stock (the "Certificates") that were converted (the "Converted Shares") into the
right to receive shares of Company Common Stock (the "Company Shares") pursuant
to Section 2.1 (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 actual delivery of the Certificates to the Exchange Agent) and (ii)
instructions for effecting the surrender of the Certificates in exchange for
certificates representing Company Shares.  Upon surrender of a Certificate to
the Exchange Agent for cancellation (or to such other agent or agents as may be
appointed by agreement of Union Electric and CIPSCO), together with a duly
executed letter of transmittal and such other documents as the Exchange Agent
may require, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of whole Company Shares
which such holder has the right to receive pursuant to the provisions of this
Article II.  In the event of a transfer of ownership of Converted Shares which
is not registered in the transfer records of Union Electric or CIPSCO, as the
case may be, a certificate representing the proper number of Company Shares may
be issued to a transferee if the Certificate representing such Converted Shares
is presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence satisfactory to the Exchange
Agent that any applicable stock transfer taxes have been paid.  Until
surrendered as contemplated by this Section 2.3, each Certificate shall be
deemed at any time after

                                      -6-

 
the Effective Time to represent only the right to receive upon such surrender
the certificate representing Company Shares and cash in lieu of any fractional
shares of Company Common Stock as contemplated by this Section 2.3.

          (c)  Distributions with Respect to Unexchanged Shares.  No dividends
or other distributions declared or made after the Effective Time with respect to
Company Shares with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the Company Shares
represented thereby and no cash payment in lieu of fractional shares shall be
paid to any such holder pursuant to Section 2.3(d) until the holder of record of
such Certificate shall surrender such Certificate.  Subject to the effect of
unclaimed property, escheat and other applicable laws, following surrender of
any such Certificate, there shall be paid to the record holder of the
certificates representing whole Company Shares 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 Company Common Stock to which such
holder is entitled pursuant to Section 2.3(d) and the amount of dividends or
other distributions with a record date after the Effective Time theretofore paid
with respect to such whole Company Shares and (ii) at the appropriate payment
date, the amount of dividends or other distributions with a record date after
the Effective Time but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole Company Shares.

          (d)  No Fractional Securities.  Notwithstanding any other provision of
this Agreement, no certificates or scrip representing fractional shares of
Company Common Stock shall be issued upon the surrender for exchange of
Certificates and such fractional shares shall not entitle the owner thereof to
vote or to any other rights of a holder of Company Common Stock.  A holder of
CIPSCO Common Stock who would otherwise have been entitled to a fractional share
of Company Common Stock shall be entitled to receive a cash payment in lieu of
such fractional share in an amount equal to the product of such fraction
multiplied by the average of the last reported sales price, regular way, per
share of CIPSCO Common Stock on the New York Stock Exchange ("NYSE") Composite
Tape for the ten business days prior to and including the last business day on
which such stock was traded on the NYSE, without any interest thereon.

          (e)  Closing of Transfer Books.  From and after the Union Electric
Effective Time or the Company Effective Time, as the case may be, the stock
transfer books of Union Electric and CIPSCO shall be closed and no transfer of
any capital stock of Union Electric or CIPSCO shall thereafter be made.  If,
after

                                      -7-

 
the Effective Time, Certificates are presented to the Company, they shall be
cancelled and exchanged for certificates representing the appropriate number of
Company Shares as provided in Section 2.1 and in this Section 2.3.

          (f)  Termination of Exchange Agent.  Any certificates representing
Company Shares deposited with the Exchange Agent pursuant to Section 2.3(a) and
not exchanged within one year after the Effective Time pursuant to this Section
2.3 shall be returned by the Exchange Agent to the Company, which shall
thereafter act as Exchange Agent.  All funds held by the Exchange Agent for
payment to the holders of unsurrendered Certificates and unclaimed at the end of
one year from the Effective Time shall be returned to the Company, after which
time any holder of unsurrendered Certificates shall look as a general creditor
only to the Company for payment of such funds to which such holder may be due,
subject to applicable law.  The Company shall not be liable to any person for
such shares or funds delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

shareholders to be held in connection with the Mergers, 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 Registration

Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and any
severance or change in control agreement (collectively, the "CIPSCO Benefit
Plans").  No CIPSCO Benefit Plan is a "multiemployer plan" as defined in Section
3(37) of ERISA.

                                      -17-

 
   (b)  Contributions.  All material contributions and other payments required
to be made for any period through the date to which this representation speaks,
by CIPSCO or any of the CIPSCO Subsidiaries to any CIPSCO Benefit Plan (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 on or before the date to which
this representation speaks, have been reflected in the CIPSCO Financial
Statements.

   (c)  Qualification; Compliance.  Each of the CIPSCO Benefit Plans intended to
be "qualified" within the meaning of Section 401(a) of the Code has been
determined by the Internal Revenue Service (the "IRS") to be so qualified or an
application for such a determination, which was filed before the expiration of
the applicable remedial amendment period, is pending, and, to the best knowledge
of CIPSCO, no circumstances exist that are reasonably expected by CIPSCO to
result in the revocation of any such determination.  CIPSCO and each of its
subsidiaries is in compliance in all material respects with, and each of the
CIPSCO Benefit Plans is and has been operated in all material respects in
compliance with, all applicable laws, rules and regulations governing such plan,
including, without limitation, ERISA and the Code.  Each CIPSCO Benefit Plan
intended to provide for the deferral of income, the reduction of salary or other
compensation, or to afford other income tax benefits, complies with the
requirements of the applicable provisions of the Code or other laws, rules and
regulations required to provide such income tax benefits.  There are no pending
or, to the knowledge of CIPSCO, threatened or anticipated claims under or in
respect of any CIPSCO Benefit Plan by or on behalf of any employee, former
employee, director, former director, or beneficiary thereof, or otherwise
involving any CIPSCO Benefit Plan (other than routine claims for benefits).

   (d)  Liabilities.  With respect to the CIPSCO Benefit Plans, individually and
in the aggregate, no event has occurred, and, to the best knowledge of CIPSCO,
there does not now exist any condition or set of circumstances, that could
subject CIPSCO or any of the CIPSCO Subsidiaries to any material liability
arising under the Code, ERISA or any other applicable law (including, without
limitation, any liability to any such plan or the Pension Benefit Guaranty
Corporation (the "PBGC")), or under any indemnity agreement to which CIPSCO or
any subsidiary thereof is a party, excluding liability for benefit claims,
administrative expenses and funding obligations payable in the ordinary course.
No event has occurred, and, to the best

                                      -18-

 
knowledge of CIPSCO, there does not now exist any condition or set of
circumstances, that could give rise to any material liability of CIPSCO or any
ERISA Affiliate (as hereinafter defined) of CIPSCO under (i) Title IV of ERISA
(other than for PBGC premium payments), (ii) Section 302 of ERISA, (iii)
Sections 412 and 4971 of the Code, or (iv) the continuation coverage
requirements of section 601 et seq. of ERISA and Section 4980B of the Code
(other than the payment of benefits required thereby), that would be a liability
of the Company or any of its ERISA Affiliates following the Closing.  The term
"ERISA Affiliate" means, with respect to any entity, trade or business, any
other entity, trade or business that is a member of a group described in Section
414(b), (c), (m) or (o) of the Code or Section 4001(b)(1) of ERISA that includes
the first entity, trade or business, or that is a member of the same "controlled
group" as the first entity, trade or business pursuant to Section 4001(a)(14) of
ERISA or other applicable laws.

   (e)  Welfare Plans.  Except as set forth in the CIPSCO Financial Statements,
none of the CIPSCO Benefit Plans that are "welfare plans", within the meaning of
Section 3(1) of ERISA, provides for any retiree benefits, other than
continuation coverage required to be provided under Section 4980B of the Code or
Part 6 of Title I of ERISA or other applicable laws.

   (f)  Documents Made Available.  CIPSCO has made available to Union Electric a
true and correct copy of each collective bargaining agreement to which CIPSCO or
any of the CIPSCO Subsidiaries is a party or under which CIPSCO or any of the
CIPSCO Subsidiaries has obligations and, with respect to each CIPSCO Benefit
Plan, where applicable, (i) such plan and the most recent summary plan
description, (ii) the most recent annual report filed with the IRS, (iii) each
related trust agreement, insurance contract, service provider or investment
management agreement (including all amendments to each such document), (iv) the
most recent determination of the IRS with respect to the qualified status of
such CIPSCO Benefit Plan, and (v) the most recent actuarial report or valuation.

   (g)  Payments Resulting from the Merger.  (i) The consummation or
announcement of any transaction contemplated by this Agreement will not (either
alone or upon the occurrence of any additional or further acts or events) result
in any (A) payment (whether of severance pay or otherwise) becoming due from
CIPSCO or any of the

                                      -19-

 
CIPSCO Subsidiaries to any officer, employee, former employee, director or
former director thereof or to the trustee under any "rabbi trust" or similar
arrangement, or (B) benefit under any CIPSCO Benefit Plan being established or
becoming accelerated, vested or payable and (ii) neither CIPSCO nor any of the
CIPSCO Subsidiaries is a party to (A) any management, employment, deferred
compensation, severance (including any payment, right or benefit resulting from
a change in control), bonus or other contract for personal services with any
officer, director or employee, (B) any consulting contract with any person who
prior to entering into such contract was a director or officer of CIPSCO, or (C)
any plan, agreement, arrangement or understanding similar to any of the
foregoing.

   (h)  Labor Agreements.  As of the date hereof, neither CIPSCO nor any of the
CIPSCO Subsidiaries is a party to any collective bargaining agreement or other
labor agreement with any union or labor organization.  To the best knowledge of
CIPSCO, as of the date hereof, there is no current union representation question
involving employees of CIPSCO or any of the CIPSCO Subsidiaries, nor does CIPSCO
know of any activity or proceeding of any labor organization (or representative
thereof) or employee group to organize any such employees.  Except as disclosed
in the CIPSCO SEC Reports filed prior to the date hereof or in Section 4.10(h)
of the CIPSCO Disclosure Schedule, (i) there is no unfair labor practice,
employment discrimination or other material complaint against CIPSCO or any of

stoppage pending, or to the best knowledge of CIPSCO, threatened, against or
involving CIPSCO, and (iii) there is no proceeding, claim, suit, action or
governmental investigation pending or, to the best knowledge of CIPSCO,
threatened, in respect of which any director, officer, employee or agent of
CIPSCO or any of the CIPSCO Subsidiaries is or may be entitled to claim
indemnification from CIPSCO or such CIPSCO Subsidiary pursuant to their
respective articles of incorporation or by-laws or as provided in the
indemnification agreements listed in Section 4.10(h) of the CIPSCO Disclosure
Schedule.

CIPSCO Subsidiaries is not in material compliance with applicable Environmental
Laws.

   (b)  Environmental Permits.  CIPSCO and each of the CIPSCO Subsidiaries has

their operations, and all such Environmental Permits are in good standing or,
where applicable, a renewal application has been timely filed and is pending
agency approval, and CIPSCO and the CIPSCO Subsidiaries are in material
compliance with all terms and conditions of the Environmental Permits, and
CIPSCO reasonably believes that any transfer, renewal or reapplication for any
Environmental Permit required as a result of the Company Merger can be
accomplished in the ordinary course of business.

Environmental Claim against CIPSCO or any of the CIPSCO Subsidiaries.

   (e)  Predecessors.  CIPSCO has no knowledge of any material Environmental
Claim pending or threatened, or of any Release of Hazardous Materials that would
be reasonably likely to form the basis of any material Environmental Claim, in

predecessor of CIPSCO or any of the CIPSCO Subsidiaries) whose liability CIPSCO
or any of the CIPSCO Subsidiaries has or may have retained or assumed either
contractually or by operation of law or against any real or personal property
which CIPSCO or any of the CIPSCO Subsidiaries formerly owned, leased or
managed, in whole or in part.

Exchange Ratio is fair from a financial point of view to the holders of CIPSCO
Common Stock.

          Section 4.17  Insurance.  Except as set forth in Section 4.17 of the

nor any of the CIPSCO Subsidiaries has received any notice of cancellation or
termination with respect to any material insurance policy of

Subsidiaries to any material liability arising under the Code, ERISA or any
other applicable law (including, without limitation, any liability to any such
plan or the PBGC), or under any indemnity agreement to which Union Electric or
any subsidiary thereof is a party, excluding liability for benefit claims,
administrative expenses and funding obligations payable in the ordinary course.

302 of ERISA, (iii) Sections 412 and 4971 of the Code, or (iv) the continuation
coverage requirements of Section 601 et seq. of ERISA and section 4980B of the
Code (other than for the payment of benefits required thereby), that would be a
liability of the Company or any of its ERISA Affiliates following the Closing.

the occurrence of any additional or further acts or events) result in any (A)
payment (whether of severance pay or otherwise) becoming due from Union Electric
or any of the Union Electric Subsidiaries to any officer, employee, former
employee, director or former director thereof or to the trustee under any "rabbi
trust" or similar arrangement, or (B) benefit under any Union Electric Benefit
Plan being established or becoming accelerated, vested or payable and (ii)

Missouri law and the Articles of Incorporation or By-laws shall be made by
independent counsel mutually acceptable to the Company and the Indemnified
Party; provided, however, that the Company shall not be liable for any
settlement effected without its written consent (which consent shall not be
unreasonably withheld).  The Indemnified Parties as a group may retain only one
law firm with respect to each related matter except to the extent there is, in
the opinion of counsel to an Indemnified Party, under applicable standards of
professional conduct, a conflict on any significant issue between positions of
such Indemnified Party and any other Indemnified Party or Indemnified Parties.

   (b)  Insurance.  For a period of six years after the Effective Time, the
Company shall cause to be maintained in effect policies of directors' and
officers' liability insurance maintained by CIPSCO and Union Electric for the
benefit of those persons who are currently covered by such policies on terms no
less favorable than the terms of such current insurance coverage; provided,
however, that the Company shall not be required to expend in any year an amount
in excess of 200% of the annual aggregate premiums currently paid by CIPSCO or
Union Electric, as the case may be, for such insurance; and provided, further,
that if the annual premiums of such insurance coverage

                                      -53-

 
exceed such amount, the Company shall be obligated to obtain a policy with the
best coverage available, in the reasonable judgment of the Board of Directors of
the Company, for a cost not exceeding such amount.

   (c)  Successors.  In the event the Company or any of its successors or
assigns (i) consolidates with or merges into any other person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any person, then and in either such case, proper provisions shall be made so
that the successors and assigns of the Company shall assume the obligations set
forth in this Section 7.5.

   (d)  Survival of Indemnification.  To the fullest extent permitted by law,
from and after the Effective Time, all rights to indemnification as of the date
hereof in favor of the employees, agents, directors and officers of CIPSCO,
Union Electric and their respective subsidiaries with respect to their
activities as such prior to the Effective Time, as provided in their respective
articles of incorporation and by-laws in effect on the date hereof, or otherwise
in effect on the date hereof, shall survive the Merger and shall continue in
full force and effect for a period of not less than six years from the Effective
Time.

   (e)  Benefit.  The provisions of this Section 7.5 are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and his or her representatives.

   Section 7.6  Disclosure Schedules.  On the date hereof, (i) Union Electric
has delivered to CIPSCO a schedule (the "Union Electric Disclosure Schedule"),
accompanied by a certificate signed by the chief financial officer of Union
Electric stating the Union Electric Disclosure Schedule is being delivered
pursuant to this Section 7.6(i) and (ii) CIPSCO has delivered to Union Electric
a schedule (the "CIPSCO Disclosure Schedule"), accompanied by a certificate
signed by the chief financial officer of CIPSCO stating the CIPSCO Disclosure
Schedule is being delivered pursuant to this Section 7.6(ii).  The CIPSCO
Disclosure Schedule and the Union Electric Disclosure Schedule are collectively
referred to herein as the "Disclosure Schedules".  The Disclosure Schedules
constitute an integral part of this Agreement and modify the respective
representations, warranties, covenants or agreements of the parties hereto
contained herein to the extent that such representations, warranties, covenants
or agreements expressly refer to the Disclosure Schedules.  Anything to the
contrary contained herein or in the Disclosure Schedules notwithstanding, any
and

                                      -54-

 
all statements, representations, warranties or disclosures set forth in the
Disclosure Schedules shall be deemed to have been made on and as of the date
hereof.

   Section 7.7  Public Announcements.  Subject to each party's disclosure
obligations imposed by law, CIPSCO and Union Electric will cooperate with each
other in the development and distribution of all news releases and other public
information disclosures with respect to this Agreement or any of the
transactions contemplated hereby and shall not issue any public announcement or
statement with respect hereto or thereto without the consent of the other party
(which consent shall not be unreasonably withheld).

   Section 7.8  Rule 145 Affiliates.  Within 30 days after the date of this
Agreement, CIPSCO shall identify in a letter to Union Electric, and Union
Electric shall identify in a letter to CIPSCO, all persons who are, and to such
person's best knowledge who will be at the Closing Date, "affiliates" of CIPSCO
and Union Electric, respectively, as such term is used in Rule 145 under the
Securities Act (or otherwise under applicable SEC accounting releases with
respect to pooling-of-interests accounting treatment).  Each of CIPSCO and Union
Electric shall use all reasonable efforts to cause their respective affiliates
(including any person who may be deemed to have become an affiliate after the
date of the letter referred to in the prior sentence) to deliver to the Company
on or prior to the Closing Date a written agreement substantially in the form
attached as Exhibit 7.8 (each, an "Affiliate Agreement").

   Section 7.9  Employee Agreements and Workforce Matters.

   (a)  Certain Employee Agreements.  Subject to Section 7.10, Section 7.14 and
Section 7.15, the Company and its subsidiaries shall honor, without
modification, all contracts, agreements, collective bargaining agreements and
commitments of the parties prior to the date hereof which apply to any current
or former employee or current or former director of the parties hereto;
provided, however, that this undertaking is not intended to prevent the Company
from enforcing such contracts, agreements, collective bargaining agreements and
commitments in accordance with their terms, including, without limitation, any
reserved right to amend, modify, suspend, revoke or terminate any such contract,
agreement, collective bargaining agreement or commitment.

                                      -55-

 
   (b) Workforce Matters.  Subject to applicable collective bargaining
agreements, for a period of three years following the Effective Time, any
reductions in workforce in respect of employees of the Company shall be made on
a fair and equitable basis, in light of the circumstances and the objectives to
be achieved, giving consideration to previous work history, job experience, and
qualifications, without regard to whether employment prior to the Effective Time
was with CIPSCO or its subsidiaries or Union Electric or its subsidiaries, and
any employees whose employment is terminated or jobs are eliminated by the
Company or any of its subsidiaries during such period shall be entitled to
participate on a fair and equitable basis in the job opportunity and employment
placement programs offered by the Company or any of its subsidiaries.  Any
workforce reductions carried out following the Effective Time by the Company and
its subsidiaries shall be done in accordance with all applicable collective
bargaining agreements, and all laws and regulations governing the employment
relationship and termination thereof including, without limitation, the Worker
Adjustment and Retraining Notification Act and regulations promulgated
thereunder, and any comparable state or local law.

   Section 7.10  Employee Benefit Plans.

   (a)  Maintenance of CIPSCO and Union Electric Benefit Plans.  Subject to
Section 7.10(b), Section 7.10(c) and Section 6.1(i), each of the CIPSCO Benefit
Plans and Union Electric Benefit Plans in effect at the date hereof shall be
maintained in effect with respect to the employees or former employees of CIPSCO
and any of its Direct Subsidiaries, on the one hand, and of Union Electric and
any of its Direct Subsidiaries, on the other hand, respectively, who are covered
by any such benefit plan immediately prior to the Closing Date (the "Affiliated
Employees") until the Company otherwise determines after the Effective Time;
provided, however, that nothing herein contained shall limit any reserved right
contained in any such CIPSCO Benefit Plan or Union Electric Benefit Plan to
amend, modify, suspend, revoke or terminate any such plan; provided, further,
however, that the Company or its subsidiaries shall provide benefits to the
Affiliated Employees for a period of not less than one year following the
Effective Time, other than with respect to plans referred to in Section 7.10(b)
and Section 7.11, which are no less favorable in the aggregate than those
provided under the CIPSCO Benefit Plans (with respect to employees and former
employees of CIPSCO and its Direct Subsidiaries), or the Union Electric Benefit
Plans (with respect to employees or former employees of Union Electric and its
Direct Subsidiaries), as the case may be.  Without limitation of the foregoing,
each participant in any such CIPSCO Benefit Plan or Union Electric Benefit Plan
shall receive credit for purposes

                                      -56-

 
of eligibility to participate, vesting, benefit accrual and eligibility to
receive benefits under any benefit plan of the Company or any of its
subsidiaries or affiliates for service credited for the corresponding purpose
under such benefit plan; provided, however, that such crediting of service shall
not operate to duplicate any benefit to any such participant or the funding for
any such benefit or cause any such CIPSCO Benefit Plan or Union Electric Benefit
Plan to fail to comply with the applicable provisions of the Code or ERISA.  Any
person hired by the Company or any of its subsidiaries after the Closing Date
who was not employed by any party hereto or its subsidiaries immediately prior
to the Closing Date shall be eligible to participate in such benefit plans
maintained, or contributed to, by the subsidiary, division or operation by which
such person is employed, provided that such person meets the eligibility
requirements of the applicable plan.

   (b)  Adoption of Company Replacement Plans.  With respect to the Union
Electric Executive Incentive Plan (the "Union Electric EIP"), the Union Electric
LTIP and the CIPSCO Management Incentive Plan (the "CIPSCO MIP"), the Company
and its subsidiaries shall adopt replacement plans as set forth in this Section
7.11(b) (collectively, the "Company Replacement Plans"), subject in each case to
shareholder approval prior to the Effective Time and subject to the shareholder
approvals described below, which approvals shall be sought by the Company as
soon as reasonably practicable following the Effective Time.  Each Company
Replacement Plan shall amend and supersede the corresponding Union Electric or
CIPSCO plan and such corresponding plan shall, as of the Effective Time, be
merged with and into the appropriate Company Replacement Plan.  The Union
Electric EIP and the CIPSCO MIP shall be replaced by a new annual bonus plan
under which cash bonuses, based on percentages of base salaries, are awarded
based upon the achievement of performance goals determined in advance by the
Human Resources Committee of the Board of Directors of the Company (the
"Committee").  With respect to those participants in the new plan who are, or
who the Committee determines are likely to be, "covered individuals" within the
meaning of Section 162(m) of the Code, the performance goals shall be objective
standards that are approved by shareholders in accordance with the requirements
for exclusion from the limits of Section 162(m) of the Code as performance-based
compensation.  The Union Electric LTIP shall be replaced by a stock compensation
plan (the "Company Stock Plan") providing for the grant of stock options, stock
appreciation rights, restricted stock, performance units and such other awards
based upon the Company Common Stock as the Board of Directors may determine,
subject to shareholder approval of the Company Stock Plan.  The Company shall
reserve 4.0 million shares for issuance under the Company Stock Plan.

                                      -57-

 
   (c)  CIPSCO Action.  Before the Effective Time, CIPSCO shall take all steps
necessary to amend (i) the CIPSCO Special Executive Retirement Plan, (ii) the
CIPSCO Excess Benefit Plan and (iii) all trusts associated with such plans,  so
that none of the transactions contemplated by this Agreement shall constitute a
"change in control" for purposes of said arrangements, subject to any required
consents of participants therein, which CIPSCO shall use its best efforts to
obtain.  Prior to or as soon as practicable after the date hereof, Union
Electric shall adopt a severance plan substantially in the form previously
provided to CIPSCO.

   Section 7.11  Stock Option and Other Stock Plans.

   (a)  Amendment of Union Electric LTIP.  Effective as of the Effective Time,
Union Electric shall amend the Union Electric LTIP and use its best efforts to
amend each underlying stock award agreement, in each case to the extent
necessary to provide that (i) none of the transactions contemplated by this
Agreement shall constitute a Change in Control for purposes of the Union
Electric LTIP, (ii) each outstanding option to purchase shares of Old Union
Electric Common Stock (each, an "Union Electric Stock Option") shall constitute
an option to acquire shares of Company Common Stock, on the same terms and
conditions as were applicable under such Union Electric Stock Option, based on
the same number of shares of the Company Common Stock as the holder of such
Union Electric Stock Option would have been entitled to receive pursuant to the
Mergers in accordance with Article II had such holder exercised such option in
full immediately prior to the Effective Time; provided that the number of
shares, the option price, and the terms and conditions of exercise of such
option, shall be determined in a manner that preserves both (A) the aggregate
gain (or loss) on the Union Electric Stock Option immediately prior to the
Effective Time and (B) the ratio of the exercise price per share subject to the
Union Electric Stock Option to the fair market value (determined immediately
prior to the Effective Time) per share subject to such option; and provided,
further, that in the case of any option to which Section 421 of the Code applies
by reason of its qualification under any of Sections 422-424 of the Code, the
option price, the number of shares purchasable pursuant to such option and the
terms and conditions of exercise of such option shall be determined in order to
comply with Section 424(a) of the Code; and (iii) each outstanding performance
dividend unit under the Union Electric Stock Plan ("Union Electric Dividend
Units") shall constitute a performance dividend based upon the same number of
shares of Company Common Stock as the holder of such Union Electric Dividend
Unit would have been entitled to receive pursuant to the Union Electric Merger
in accordance with Article II had such holder been the

                                      -58-

 
absolute owner, immediately before the Effective Time, of the shares of Union
Electric Common Stock on which such Union Electric Dividend Unit is based, with
such adjustments to the performance goals for such Union Electric Dividend Units
as the Union Electric Human Resources Committee shall determine to be fair and
equitable in light of the Merger, and otherwise on the same terms and conditions
as governed such Union Electric Dividend Unit immediately before the Effective
Time.  At the Effective Time, the Company shall assume each agreement relating
to Union Electric Stock Options and Union Electric Dividend Units under the
Union Electric Stock Plan, each as amended as previously provided.  As soon as
practicable after the Effective Time, the Company shall deliver to the holders
of Union Electric Stock Options and Union Electric Stock Awards appropriate
notices setting forth such holders' rights pursuant to the Company Stock Plan
and each underlying stock award agreement, each as assumed by the Company.

   (b)  Company Action.  With respect to each of the Union Electric LTIP, the
Savings Investment Plan, the CIPS Employee Stock Ownership Plan, the CIPS 401(k)
Plans, and any other plans under which the delivery of Union Electric or CIPSCO
Common Stock is required upon payment of benefits, grant of awards or exercise
of options (the "Stock Plans"), the Company shall take all corporate action
necessary or appropriate to (i) provide for the issuance or purchase in the open
market of Company Common Stock rather than Union Electric Common Stock or CIPSCO
Common Stock, as applicable, pursuant thereto, and otherwise to amend such stock
plans to reflect this Agreement and the Mergers, (ii) 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, or to enable such Stock Plan
to comply with Rule 16b-3 promulgated under the Exchange Act, (iii) reserve for
issuance under such plan or otherwise provide a sufficient number of shares of
Company Common Stock for delivery upon payment of benefits, grant of awards or
exercise of options under such Stock Plan and (iv) as soon as practicable after
the Effective Time, file registration statements on Form S-3 or Form S-8 or
amendments on such forms to the Form S-4 Registration Statement, as the case may
be (or any successor or other appropriate forms), with respect to the shares of
Company Common Stock subject to such Stock Plan to the extent such registration
statement is required under applicable law, and the Company shall use its best
efforts to maintain the effectiveness of such registration statements (and
maintain the current status of the prospectuses contained therein) for so long
as such benefits and grants remain payable and 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,

                                      -59-

 
the Company shall administer the Stock Plans, where applicable, in a manner that
complies with Rule 16b-3 promulgated under the Exchange Act.

   Section 7.12  No Solicitations.  Each party hereto shall not, and shall cause
its Direct Subsidiaries not to, and shall not permit any of its Representatives
or subsidiaries that are not Direct Subsidiaries to, and shall use its best
efforts to cause such persons not to, directly or indirectly:  initiate, solicit
or encourage, or take any action to facilitate the making of any offer or
proposal which constitutes or is reasonably likely to lead to, any Business
Combination Proposal (as defined below), or, in the event of an unsolicited
Business Combination Proposal, except to the extent required by their fiduciary
duties under applicable law if so advised in a written opinion of outside
counsel, engage in negotiations or provide any information or data to any person
relating to any Business Combination Proposal.  Each party hereto shall notify
the other party orally and in writing of any such inquiries, offers or proposals
(including, without limitation, the terms and conditions of any such proposal
and the identity of the person making it), within 24 hours of the receipt
thereof, shall keep the other party informed of the status and details of any
such inquiry, offer or proposal, and shall give the other party five days'
advance notice of any agreement to be entered into with or any information to be
supplied to any person making such inquiry, offer or proposal.  Each party
hereto shall immediately cease and cause to be terminated all existing
discussions and negotiations, if any, with any parties conducted heretofore with
respect to any Business Combination Proposal.  As used in this Section 7.12,
"Business Combination Proposal" shall mean any tender or exchange offer,
proposal for a merger, consolidation or other business combination involving any
party to this Agreement or any of its material subsidiaries, or any proposal or
offer (in each case, whether or not in writing and whether or not delivered to
the stockholders of a party generally) to acquire in any manner, directly or
indirectly, a substantial equity interest in or a substantial portion of the
assets of any party to this Agreement or any of its material subsidiaries, other
than pursuant to the transactions contemplated by this Agreement.  Nothing
contained herein shall prohibit a party from taking and disclosing to its
stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act
with respect to a Business Combination Proposal by means of a tender offer.

   Section 7.13  Company Board of Directors.  CIPSCO's and Union Electric's
respective Boards of Directors will take such action as may be necessary to
cause the number of directors comprising the full Board of Directors of the
Company at

                                      -60-

 
the Effective Time to be 15 persons, including Mr. Clifford L. Greenwalt and
four non-management directors of CIPSCO to be designated by CIPSCO prior to the
Effective Time, and Mr. Charles W. Mueller and nine other directors of Union
Electric designated by Union Electric prior to the Effective Time.  If, prior to
the Effective Time, any of such designees shall decline or be unable to serve,
the party which designated such person shall designate another person to serve
in such person's stead, except that a replacement for the position of Chairman
of the Board of Directors of the Company shall be chosen by the Board of
Directors of Union Electric.  CIPSCO's and Union Electric's respective Boards of
Directors will also take such action as may be necessary to cause the committees
of the Board of Directors of the Company at the Effective Time to consist of (i)
two representatives designated by CIPSCO and six representatives designated by
Union Electric, in the case of the Executive Committee, (ii) one representative
designated by CIPSCO and three representatives designated by Union Electric, in
the case of the Human Resources Committee, (iii) one representative designated
by CIPSCO and three representatives designated by Union Electric, in the case of
the Nominating Committee, (iv) two representatives designated by CIPSCO and four
representatives designated by Union Electric, in the case of the Audit Committee
and (v) two representatives designated by CIPSCO and four representatives
designated by Union Electric, in the case of the Contributions Committee, with
such persons in each case to be designated prior to the Effective Time.

   Section 7.14  Company Officers.  Mr. Charles W. Mueller shall be the Chairman
of the Board of Directors, President and Chief Executive Officer of the Company
at the Effective Time and Mr. Clifford L. Greenwalt shall be Vice Chairman of
the Company's Board of Directors.  The other officers of the Company at the
Effective Time shall be such officers as may be designated by the Board of
Directors of the Company.

   Section 7.15  Boards of Directors of Subsidiaries.  At the Effective Time,
the Board of Directors of CIPS shall be expanded to include three additional
directorships, and shall initially consist of (i) the directors serving
immediately prior to the Effective Time and (ii) Mr. Charles W. Mueller and two
additional persons designated by Union Electric, which two persons, together
with Mr. Charles W. Mueller, shall fill the vacancies created by the expansion
of the Board of Directors of CIPS.  At the Effective Time, the Board of
Directors of Union Electric, as the surviving corporation in the Union Electric
Merger, shall initially consist of Mr. Charles W. Mueller, Mr. Clifford L.
Greenwalt and such other nominees as shall be determined by the Company.

                                      -61-

 
   Section 7.16  Post-Merger Operations.  Following the Effective Time, the
Company shall conduct its operations in accordance with the following:

   (a)  Principal Corporate Offices.  The principal corporate office of the
Company shall be located in St. Louis, Missouri.  From the Effective Time CIPS
shall maintain its principal corporate office in Springfield, Illinois.

   (b)  Maintenance of Separate Existence.  CIPS shall continue its separate
corporate existence, operating under the name "Central Illinois Public Service
Company".

   (c)  Charities.  After the Effective Time, the Company shall provide
charitable contributions and community support within the service areas of the
parties and each of their respective subsidiaries at levels substantially
comparable to the levels of charitable contributions and community support
provided by the parties and their respective subsidiaries within their service
areas within the two-year period immediately prior to the Effective Time.

   Section 7.17  Expenses.  Subject to Section 9.3, all costs and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such expenses, except that those
expenses incurred in connection with printing the Joint Proxy/Registration
Statement, as well as the filing fee relating thereto, shall be shared equally
by CIPSCO and Union Electric.

   Section 7.18  Further Assurances.  Each party will, and will cause its Direct
Subsidiaries to, execute such further documents and instruments and take such
further actions as may reasonably be requested by any other party in order to
consummate the Mergers in accordance with the terms hereof.  The parties
expressly acknowledge and agree that, although it is their current intention to
effect a business combination among themselves in the form contemplated by this
Agreement, it may be preferable to effectuate such a business combination by
means of an alternative structure in light of the conditions set forth in
Section 8.1(e), Section 8.2(e), and Section 8.3(e).  Accordingly, if the only
conditions to the parties' obligations to consummate the Mergers which are not
satisfied or waived are receipt of any one or more of the CIPSCO Required
Consents, CIPSCO Required Statutory Approvals, Union Electric Required Consents
or Union Electric Required Statutory Approvals, and the adoption of an
alternative structure (that otherwise substantially preserves for CIPSCO and
Union Electric the economic

                                      -62-

 
benefits of the Mergers) would result in such conditions being satisfied or
waived, then the parties shall use their respective best efforts to effect a
business combination among themselves by means of a mutually agreed upon
structure other than the Mergers that so preserves such benefits; provided that,
prior to closing any such restructured transaction, all material third-party and
Governmental Authority declarations, filings, registrations, notices,
authorizations, consents or approvals necessary for the effectuation of such
alternative business combination shall have been obtained and all other
conditions to the parties' obligations to consummate the Mergers, as applied to
such alternative business combination, shall have been satisfied or waived.

   Section 7.19  Charter and By-Law Amendments.  Prior to the mailing of the
Joint Proxy Statement/Prospectus, Union Electric and CIPSCO shall agree upon
amendments to be effected to the articles of incorporation of the Company, and
the by-laws of the Company, and the Company shall take all actions necessary so
that such amendments become effective no later than the Effective Time.

   Section 7.20  Transfers of Illinois Assets.  Prior to the Closing and subject
to the next sentence of this Section 7.20, Union Electric shall use reasonable
efforts and shall have taken such action as is necessary to effect the transfer
of the assets set forth on Schedule 7.20 of this Agreement to CIPS, which
transfers shall be effected immediately subsequent to the Company Merger.  To
the extent any of such assets set forth in Schedule 7.20 cannot be conveyed to
CIPS, the parties hereto shall use reasonable efforts to implement alternative
arrangements (such as licensing arrangements) with respect to such non-conveyed
assets as shall be mutually agreed upon by Union Electric and CIPSCO.


                                  ARTICLE VIII
      
                                   CONDITIONS

   Section 8.1  Conditions to Each Party's Obligation to Effect the Mergers.
The respective obligations of each party to effect the Mergers shall be subject
to the satisfaction on or prior to the Closing Date of the following conditions,
except, to the extent permitted by applicable law, that such conditions may be
waived in writing pursuant to Section 9.5 by the joint action of the parties
hereto:

                                      -63-

 
   (a)  Shareholder Approvals.  The Union Electric Shareholders' Approval and
the CIPSCO Shareholders' Approval shall have been obtained.

   (b)  No Injunction.  No temporary restraining order or preliminary or
permanent injunction or other order by any federal or state court preventing
consummation of the Mergers shall have been issued and be continuing in effect,
and the Mergers and the other transactions contemplated hereby shall not have
been prohibited under any applicable federal or state law or regulation.

   (c)  Registration Statement.  The Registration Statement shall have become
effective in accordance with the provisions of the Securities Act, and no stop
order suspending such effectiveness shall have been issued and remain in effect.

   (d)  Listing of Shares.  The shares of Company Common Stock issuable in the
Mergers pursuant to Article II shall have been approved for listing on the NYSE
upon official notice of issuance.

   (e)  Statutory Approvals.  The CIPSCO Required Statutory Approvals and the
Union Electric Required Statutory Approvals shall have been obtained at or prior
to the Effective Time, such approvals shall have become Final Orders (as defined
below) and such Final Orders shall not impose terms or conditions which, in the
aggregate, would have, or insofar as reasonably can be foreseen, could have, a
material adverse effect on the business, assets, financial condition or results
of operations of the Company and its prospective subsidiaries taken as a whole
or on the Company prospective utility subsidiaries located in the State of
Missouri taken as a whole, or on its prospective utility subsidiaries located in
the State of Illinois taken as a whole or which would be materially inconsistent
with the agreements of the parties contained herein.  A "Final Order" means
action by the relevant regulatory authority which has not been reversed, stayed,
enjoined, set aside, annulled or suspended, with respect to which any waiting
period prescribed by law before the transactions contemplated hereby may be
consummated has expired, and as to which all conditions to the consummation of
such transactions prescribed by law, regulation or order have been satisfied.

   (f)  Pooling.  Each of CIPSCO and Union Electric shall have received a letter
of its independent public accountants, dated the Closing Date, in form and
substance

                                      -64-

 
reasonably satisfactory, in each case, to CIPSCO and Union Electric, stating
that the transactions effected pursuant to this Agreement will qualify as a
pooling of interests transaction under GAAP and applicable SEC regulations.

   (g)  Dissenters' Rights.  The number of Union Electric Dissenting Shares
shall not constitute more than 5% of the number of issued and outstanding shares
of Union Electric Common Stock and Union Electric Preferred Stock, taken
together as a single class for this purpose.

   Section 8.2  Conditions to Obligation of Union Electric to Effect the
Mergers.  The obligation of Union Electric to effect the Merger shall be further
subject to the satisfaction, on or prior to the Closing Date, of the following
conditions, except as may be waived by Union Electric in writing pursuant to
Section 9.5:

   (a)  Performance of Obligations of CIPSCO.  CIPSCO (and/or its appropriate
subsidiaries) shall have performed its agreements and covenants contained in
Sections 6.1(b) and 6.1(c) and shall have performed in all material respects its
other agreements and covenants contained in or contemplated by this Agreement
and the CIPSCO Stock Option Agreement required to be performed by it at or prior
to the Effective Time.

   (b)  Representations and Warranties.  The representations and warranties of
CIPSCO set forth in this Agreement and the CIPSCO Stock Option Agreement shall
be true and correct (i) on and as of the date hereof and (ii) on and as of the
Closing Date with the same effect as though such representations and warranties
had been made on and as of the Closing Date (except for representations and
warranties that expressly speak only as of a specific date or time other than
the date hereof or the Closing Date which need only be true and correct as of
such date or time) except in each of cases (i) and (ii) for such failures of
representations or warranties to be true and correct (without regard to any
materiality qualifications contained therein) which, individually or in the
aggregate, would not be reasonably likely to result in a CIPSCO Material Adverse
Effect.

   (c)  Closing Certificates.  Union Electric shall have received a certificate
signed by the chief financial officer of CIPSCO, dated the Closing Date, to the
effect that, to the best of such officer's knowledge, the conditions set forth
in Section 8.2(a) and Section 8.2(b) have been satisfied.

                                      -65-

negotiations entered into pursuant to clause (ii) below, such fiduciary duties
would also require the directors to reconsider such commitment as a result of
such tender offer or other written offer or proposal; and (ii) prior to any such
termination, Union Electric shall, and shall cause its respective financial and

Directors of CIPSCO shall have been advised in a written opinion of outside
counsel that notwithstanding a binding commitment to consummate an agreement of
the nature of this Agreement entered into in the proper exercise of their
applicable fiduciary duties, and notwithstanding all concessions which may be
offered by Union Electric in negotiations entered into pursuant to clause (ii)
below, such fiduciary duties would also require the directors to reconsider such

   Section 9.3  Termination Fee; Expenses.

   (a)  Termination Fee upon Breach or Withdrawal of Approval.  If this
Agreement is terminated at such time that this Agreement is terminable pursuant
to one (but not both) of (x) Section 9.1(g)(i) or (ii) or (y) Section 9.1(h)(i) 
or (ii), then: (i) the breaching party shall promptly (but not later than five

paid as specified above and shall not be limited to $10 million), be entitled to
retain such additional amounts as such non-breaching party may be entitled to
receive at law or in equity; and (ii) if (x) at the time of the

                                      -71-

 
breaching party's willful breach of this Agreement, there shall have been a

party or an affiliate thereof becomes a subsidiary of such offeror or a

(and as a condition to the closing) of such breaching party becoming such a
subsidiary or of such Business Combination, will pay to the non-breaching party
an additional fee equal to $30 million in cash; provided that in no event shall 
the additional termination fee provided for in Section 9.3(b) be payable if the 
additional fee referred to in this Section 9.3(a)(ii) has been paid.

   (b)  Additional Termination Fee.  If (i) this Agreement (x) is terminated by

such agreement is signed, then at the closing (and as a condition to the
closing) of such Target Party becoming such a subsidiary or of such Business
Combination, will pay to the other party a termination fee equal

                                      -72-

non-breaching party (including, without limitation, fees and expenses payable to
all legal, accounting, financial, public relations and other professional
advisors arising out of, in connection with or related to the Merger or the
transactions contemplated by this Agreement).

   (c)  Expenses.  The parties agree that the agreements contained in this
Section 9.3 are an integral part of the transactions contemplated by the
Agreement and constitute liquidated damages and not a penalty.  If one party
fails to promptly pay to the other any fee due hereunder, the defaulting party
shall pay the costs and expenses (including legal fees and expenses) in
connection with any action, including the filing of any lawsuit or other legal
action, taken to collect payment, together with interest on the amount of any

pursuant to the terms of the CIPSCO Stock Option Agreement, as the case may be,
shall be the amount paid pursuant to Section 7(a)(i) and 7(a)(ii) thereof.

   Section 9.4  Amendment.  This Agreement may be amended by the Boards of
Directors of the parties hereto, at any time before or after approval hereof by
the shareholders of CIPSCO and Union Electric and prior to the Effective Time,
but after such approvals, no such amendment shall (i) alter or change the amount
or kind of shares, rights or any of the proceedings of the treatment of shares
under Article II, or (ii) alter or change any of the terms and conditions of

would materially adversely affect the rights of holders of CIPSCO capital stock
or Union Electric capital stock, except for alterations or changes that could
otherwise be adopted by the Board of Directors of the Company, without the
further approval of such shareholders, as applicable.  This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties hereto.

Notwithstanding the foregoing and any other provision of this Agreement, and in
