Purchaser (as defined below) is not aware of any state where the making of the Offer is prohibited by administrative or judicial action pursuant to any valid state statute. If Purchaser becomes aware of any valid state statute prohibiting the making of the Offer or the acceptance of the Shares pursuant thereto, Purchaser shall make a good faith effort to comply with such statute or seek to have such statute declared inapplicable to the Offer. If, after such good faith effort, Purchaser cannot comply with such state statute, the Offer will not be made to (nor will tenders be accepted from or on behalf of) holders of Shares in such state. In any jurisdiction where the securities, "blue sky" or other laws require the Offer to be made by a licensed broker or dealer, the Offer shall be deemed to be made on behalf of Purchaser by Credit Suisse First Boston Corporation ("Credit Suisse First Boston" or the "Dealer Manager") or one or more registered brokers or dealers licensed under the laws of such jurisdiction.

Following the consummation of the Offer, the Purchaser intends to effect the Merger (as defined below) described below. THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME ON MONDAY, APRIL 17, 2000, UNLESS THE OFFER IS EXTENDED. THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY TENDERED AND NOT PROPERLY WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER ENOUGH SHARES SO THAT, INCLUDING THE SHARES PARENT ALREADY BENEFICIALLY OWNS, PARENT WOULD CONTROL TWO-THIRDS OF THE OUTSTANDING SHARES (THE "MINIMUM CONDITION"). THE OFFER IS ALSO SUBJECT TO THE OTHER CONDITIONS SET FORTH IN THE OFFER TO PURCHASE. SEE SECTION 12, "CONDITIONS OF THE OFFER," OF THE OFFER TO PURCHASE. The special committee of the Board of Directors of the Company has determined that the Offer and the Merger are fair to, advisable and in the best interests of the Company and its stockholders, and has recommended to the Board of Directors of the Company that it recommend to the Conning stockholders acceptance of the Offer and, if necessary, approval of the Merger Agreement (as defined below) and the Offer. THE BOARD OF DIRECTORS OF THE COMPANY HAS DETERMINED THAT, BASED UPON THE RECOMMENDATION OF THE SPECIAL COMMITTEE AND OTHER CONSIDERATIONS, THE OFFER AND THE MERGER ARE FAIR TO, ADVISABLE AND IN THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS, AND HAS VOTED TO RECOMMEND TO THE CONNING STOCKHOLDERS ACCEPTANCE OF THE OFFER AND, IF NECESSARY, APPROVAL OF THE MERGER AGREEMENT. THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS TENDER THEIR SHARES PURSUANT TO THE OFFER AND APPROVE AND ADOPT THE MERGER AGREEMENT. The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of March 9, 2000 (the "Merger Agreement"), among Parent, Purchaser and the Company pursuant to which, following the consummation of the Offer and in accordance with the Missouri General and Business Corporation Law, and subject to the satisfaction or waiver of certain conditions, Purchaser will be merged with and into the Company (the "Merger"), with the Company continuing as the surviving corporation and as an indirect wholly owned subsidiary of Parent. The purpose of the Offer and the Merger is to enable Parent to acquire control of the entire equity interest in Conning. At the effective time of the Merger (the "Effective Time"), each Share issued and outstanding immediately prior to the Effective Time (other than any Shares held by Parent, Purchaser, any direct or indirect wholly owned subsidiary of Parent or Purchaser, in the treasury of the Company or by any wholly owned subsidiary of the Company, and other than Shares, if any, held by stockholders who validly perfect their appraisal rights under Missouri law) will be converted into the right to receive $12.50 in cash, without interest, or any higher price that is paid in the Offer (less any withholding taxes required under applicable law). The Merger Agreement is more fully described in the Offer to Purchase. For purposes of the Offer, Purchaser will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered to Purchaser and not properly withdrawn if, as and when Purchaser gives oral or written notice to the Depositary of Purchaser's acceptance of such Shares for payment pursuant to the Offer. In all cases, upon the terms and subject to the conditions of the Offer, payment for Shares purchased pursuant to the Offer, including during any subsequent offering period, will be made by deposit of the purchase price therefor with the 2 3 Depositary, which will act as agent for tendering stockholders for the purpose of receiving payment from Purchaser and transmitting payment to validly tendering stockholders. Under no circumstances will interest on the purchase price for Shares be paid by Purchaser, regardless of any extension of the Offer or any delay in making such payment. In all cases, payment for Shares accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of (i) certificates representing Shares (the "Share Certificates") or timely confirmation of the book-entry transfer of such Shares into the Depositary's account at The Depository Trust Company ("DTC") pursuant to the procedures set forth in Section 3, "Procedures for Accepting the Offer and Tendering Shares," of the Offer to Purchase, (ii) the Letter of Transmittal (or a manually signed facsimile thereof), delivered with the Offer to Purchase, properly completed and duly executed, with any required signature guarantees or an Agent's Message (as defined in the Offer to Purchase) in connection with a book-entry transfer of Shares, and (iii) any other documents required by the Letter of Transmittal. If any of the conditions set forth in the Offer to Purchase that relate to the Purchaser's obligations to purchase the Shares are not satisfied by 12:00 Midnight, New York City time, on Monday, April 17, 2000 (or any other time then set as the Expiration Date), the Purchaser may, subject to the Merger Agreement, elect to, (i) extend the Offer and, subject to applicable withdrawal rights, retain all tendered Shares until the expiration of the Offer, as extended, (ii) subject to complying with applicable rules and regulations of the Securities and Exchange Commission, accept for payment all Shares so tendered and not extend the Offer, or (iii) terminate the Offer and not accept for payment any Shares and return all tendered Shares to tendering shareholders. The term "Expiration Date" means 12:00 Midnight, New York City time, on Monday, April 17, 2000, unless the Purchaser shall have extended the period of time for which the Offer is open, in which event the term "Expiration Date" shall mean the latest time and date at which the Offer, as so extended by the Purchaser shall expire. Subject to the terms and conditions set forth in the Offer to Purchase and the provisions of the Merger Agreement and the applicable rules and regulations of the Securities and Exchange Commission (the "SEC"), Purchaser expressly reserves the right, in its sole discretion, at any time and from time to time, to extend the period of time during which the Offer is open and thereby to delay acceptance for payment of, and payment for, any Shares, if the conditions to the Offer described in Section 12, "Conditions of the Offer," of the Offer to Purchase have not been satisfied or earlier waived. During any such extension, all Shares previously tendered and not properly withdrawn will remain subject to the Offer, subject to the rights of a tendering stockholder to withdraw such stockholder's Shares. Subject to the provisions of the Merger Agreement and the applicable rules and regulations of the SEC, the Purchaser also reserves the right, in its sole discretion, at any time or from time to time, to: (1) terminate the Offer (whether or not any Shares have previously been purchased pursuant to the Offer) if the conditions referred to in Section 12, "Conditions of the Offer," of the Offer to Purchase has not been satisfied or earlier waived or upon the occurrence of any event specified in such section; and (2) waive any such unsatisfied condition; or (3) except as set forth in the Merger Agreement, otherwise amend the Offer in any respect, in each case, by giving oral or written notice of the termination, waiver or amendment to the Depositary and, other than, in the case of any waiver, by making a public announcement thereof. 3 4 Any extension, delay, termination or amendment of the Offer will be followed as promptly as practicable by a public announcement. An announcement in the case of an extension will be made no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date. In addition, following the Expiration Date (as it may be so extended) and the purchase of Shares in the Offer, there may be a subsequent offering period, lasting for at least three and not more than 20 business days; stockholders who tender Shares during a subsequent offering period will not have the right to withdraw their Shares during such subsequent offering period. THE PURCHASER EXPECTS TO MAKE A SUBSEQUENT OFFERING PERIOD AVAILABLE, UNLESS THERE ARE VALIDLY TENDERED AND NOT PROPERLY WITHDRAWN ENOUGH SHARES SO THAT, INCLUDING THE SHARES PARENT ALREADY BENEFICIALLY OWNS, PARENT WOULD CONTROL 90% OF THE OUTSTANDING SHARES, IN WHICH CASE THE MERGER WILL BE CONSUMMATED AS SOON AS POSSIBLE AFTER THE EXPIRATION DATE AND WITHOUT A VOTE OF COMPANY STOCKHOLDERS. Conning stockholders who had not previously tendered their Shares will receive the same price per Share upon completion of the merger. Tenders of Shares made pursuant to the Offer are irrevocable, except that Shares tendered pursuant to the Offer (except during any subsequent offering period) may be withdrawn at any time on or prior to the Expiration Date and, unless theretofore accepted for payment as provided in the Offer to Purchase, may also be withdrawn at any time after May 19, 2000. In order for a withdrawal to be effective, a written or facsimile transmission notice of withdrawal must be timely received by the Depositary at one of its addresses set forth on the back cover of the Offer to Purchase. Any such notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn, and (if Share Certificates have been tendered) the name of the registered holder of the Shares as set forth in the Share Certificate, if different from that of the person who tendered such Shares. If Share Certificates evidencing Shares to be withdrawn have been delivered or otherwise identified to the Depositary, then prior to the physical release of such certificates, unless the Shares have been tendered by an Eligible Institution (as defined in the Offer to Purchase), the tendering stockholder must submit the serial numbers shown on the particular certificates evidencing the Shares to be withdrawn and the signature on the notice of withdrawal must be guaranteed by an Eligible Institution. If Shares have been tendered pursuant to the procedures for book-entry transfer as set forth in Section 3, "Procedures for Accepting the Offer and Tendering Shares," of the Offer to Purchase, any notice of withdrawal must also specify the name and number of the account at the appropriate Book-Entry Transfer Facility (as defined in the Offer to Purchase) to be credited with the withdrawn Shares, in which case a notice of withdrawal will be effective if delivered to the Depositary by any method of delivery described in this paragraph. Withdrawals of Shares may not be rescinded. Any Shares properly withdrawn will thereafter be deemed not validly tendered for purposes of the Offer, but may be tendered at any subsequent time prior to the Expiration Date by following any of the procedures described in Section 3, "Procedures for Accepting the Offer and Tendering Shares," of the Offer to Purchase. All questions as to the form and validity (including time of receipt) of notices of withdrawal will be determined by Purchaser, in its sole discretion, whose determination shall be final and binding. The receipt of cash in exchange for Shares pursuant to the Offer (or the Merger) will be a taxable transaction for U.S. federal income tax purposes and may also be a taxable transaction under the applicable state, local or foreign tax laws. Generally, a stockholder who receives cash in exchange for Shares pursuant to the Offer (or the Merger) will recognize gain or loss for U.S. 4 5 federal income tax purposes equal to the difference between the amount of cash received and such stockholder's adjusted tax basis in the Shares exchanged therefor. Provided that such Shares constitute capital assets in the hands of the stockholder, such gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the holder has held the Shares for more than one year at the time of sale. The maximum U.S. federal income tax rate applicable to individual taxpayers on long-term capital gain is 20%, and the deductibility of capital losses is subject to limitations. ALL STOCKHOLDERS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES OF THE OFFER AND THE MERGER TO THEM, INCLUDING THE APPLICABILITY AND EFFECT OF THE ALTERNATIVE MINIMUM TAX AND ANY STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX LAWS AND OF CHANGES IN SUCH TAX LAWS. For a more complete description of certain U.S. federal income tax consequences of the Offer and the Merger see Section II, "Purpose of, Alternative to, Reasons for and Effects of the Tender Offer and the Merger," of the Offer to Purchase.
