(a) At the Union Electric Effective Time, by virtue of the Union Electric Merger and without any action on the part of any holder of any capital stock of Union Electric or Merger Sub: -3- (i) Conversion of Merger Sub Stock. Each share of Common Stock, par value $5.00 per share, of Merger Sub (the "Merger Sub Common Stock") shall be converted into one share of common stock of the surviving corporation in the Union Electric Merger. (ii) Cancellation of Union Electric Treasury Stock. Each share of Union Electric Common Stock that is owned by Union Electric as treasury stock and all shares of Union Electric Common Stock that are owned, directly or indirectly, by Union Electric or CIPSCO or any of their respective wholly owned subsidiaries shall be cancelled and shall cease to exist and no stock of the Company or other consideration shall be delivered in exchange therefor. (iii) Conversion of Union Electric Common Stock. Each issued and outstanding share of Common Stock, par value $5.00 per share, of Union Electric (the "Union Electric Common Stock"), other than Union Electric Dissenting Shares (as defined in Section 2.2) and shares cancelled pursuant to Section 2.1(a)(ii) of this Agreement, shall be converted into the right to receive one (the "Union Electric Exchange Ratio") fully paid and non-assessable share of Common Stock, par value $5.00 per share, of the Company ("Company Common Stock"). Upon such 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.

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.

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.

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 7.18 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.
