As of that date, these selling stockholders had supplied us with information indicating that, collectively, they owned more than the $110,945,000 aggregate principal amount at maturity of LYONs currently outstanding (which amount would be exchangeable into a maximum 3,187,606 shares of non-voting common stock). This reflects, we believe, that one or more selling stockholders supplied us with information for inclusion in the table and then subsequently (i) exercised their right to require EVM to repurchase their LYONs, in whole or in part, for cash on August 13, 2002, pursuant to the terms of the Indenture governing the LYONs; and/or (ii) sold their LYONs in transactions exempt from the registration requirements of the Securities Act of 1933, as amended, to persons who also supplied us information with respect to the shares deliverable upon exchange of the same LYONs. (2) The number of shares of non-voting common stock deliverable upon exchange of the LYONs are subject to change under certain circumstances described in the Indenture governing the LYONs. As a result, the number of shares of non-voting common stock deliverable upon exchange of the LYONs may increase or decrease at any time. (3) Assumes that the full amount of LYONs reported as held by a selling stockholder is exchanged for shares of non-voting common stock at an exchange rate of 28.7314 shares of non-voting common stock per $1,000 principal amount at maturity of LYONs, and that all shares received upon exchange are offered hereunder by that selling stockholder. Since exchange of the LYONs for shares of non-voting common stock is conditioned upon the occurrence of specified events, and since Eaton Vance Management has the right to pay cash in lieu of delivering shares of non-voting common stock upon exchange, there can be no assurance that any selling stockholder will be able to exchange its LYONs, or that it will receive shares of non-voting common stock upon any such exchange. (4) Calculated based on Rule 13d-3(d)(1)(i) of the Exchange Act, using 132,872,824 shares of non-voting common stock outstanding as of January 31, 2005. In calculating this amount for each holder, we treated as outstanding the number of shares of non-voting common stock deliverable upon exchange of all of that holder's LYONs, but we did not assume exchange of any other holder's LYONs. (5) Merrill Lynch, Pierce, Fenner & Smith, Inc. ("Merrill Lynch") is not aware of any position, office, or directorship relationship with the company or its affiliates; however, Merrill Lynch may or may not have, from time to time, acted in a financial investment advisory capacity to the company or its affiliates. 3 (6) The total non-voting common stock share figure above represents the maximum number of shares deliverable upon exchange of the aggregate principal amount at maturity of LYONs outstanding as of March 24, 2005. Accordingly, this figure represents the maximum number of shares of non-voting common stock that could be sold hereunder. The Prospectus, together with all Prospectus Supplements, constitutes the Prospectus required to be delivered by Section 5(b) of the Securities Act of 1933, as amended, with respect to offers and sales of non-voting common stock deliverable upon exchange of the LYONs. 4
