Stern ("Linda Stern" or "Mrs. Stern") and the Estate of Howard Stern (the "H. Stern Estate" and, with Linda Stern, the "Reporting Persons") on January 23, 2006, relating to the acquisition of beneficial ownership of shares of common stock, par value $0.10 per share (the "E-Z-EM Common Stock"), of E-Z-EM, Inc. ("E-Z-EM"). Unless otherwise indicated, all capitalized terms used herein shall have the meanings set forth in the Statement and, unless amended hereby, all information previously filed remains in effect. Item 3. Source and Amount of Funds or Other Consideration. Item 3 is hereby deleted and replaced in its entirety by the following: Howard S. Stern ("Howard Stern" or "Mr. Stern") died on December 28, 2005. At the time of his death, Mr. Stern beneficially owned 1,981,279 shares of E-Z-EM Common Stock, including options for 33,475 shares, of which 100,305 shares were jointly owned, with right of survivorship, with Linda Stern. Mr. Stern obtained these shares in connection with the founding of E-Z-EM in 1962 and through subsequent stock splits, stock dividends, stock grants received as a member of the E-Z-EM board of directors, and stock option exercises. He received the outstanding stock options as part of his compensation for serving as Chairman and a director of E-Z-EM. On January 13, 2006, the Nassau County Surrogate's Court issued Letters Testamentary appointing Linda Stern, Mr. Stern's wife, the executor of the H. Stern Estate under the last will and testament of Howard Stern (the "H. Stern Will"). Under the H. Stern Will, Mrs. Stern is a discretionary beneficiary of a "credit shelter" trust, the sole lifetime beneficiary of a "QTIP" trust, which is the beneficiary of one-half of Mr. Stern's residuary estate, and the direct outright beneficiary of the other-half of the residuary estate. She is also a co-trustee of the two trusts. Substantially all of the shares of E-Z-EM Common Stock owned by the H. Stern Estate will pass into Mr. Stern's residuary estate. Item 4. Purpose of Transaction Item 4 is hereby amended by adding the following immediately before the last paragraph thereof. On May 18, 2006 Mrs. Stern entered into a sales plan for E-Z-EM Common Stock with Goldman, Sachs & Co. ("Goldman, Sachs"). The sales plan is intended to comply with the requirements of Rule 10b5-1(c) under the Securities Exchange Act of 1934. The sales plan, which will terminate no later than December 29, 2006, provides for sales through Goldman, Sachs of up to 64,000 shares of E-Z-EM Common Stock during the term of the plan, commencing when sales begin under a similar sales plan to be entered into at a later date by Mrs. Stern with respect to shares of common stock of AngioDynamics, Inc., but no earlier than July 2006. Mrs. Stern has adopted the sales plan for diversification and liquidity purposes. Mrs. Stern may modify the sales plan from time to time or terminate the plan in accordance with its terms. The sales plan with Goldman, Sachs is filed as Exhibit 10.6 to this Amendment No. 1 and is incorporated by reference into this Item 4. 4 Item 5 Interest in Securities of the Issuer. Items 5(a) and (b) of the Statement are hereby deleted and replaced in their entirety by the following: (a) The H. Stern Estate has direct beneficial ownership of 1,880,974 shares of E-Z-EM Common Stock, which includes 33,475 shares subject to options that became immediately exercisable in full upon Mr. Stern's death and which constitute 17.3% of the issued and outstanding shares of E-Z-EM Common Stock. The number of shares, exercise prices and expiration dates of the options are as follows: No. of Shares Exercise Price per Share Expiration Date ------------- ------------------------ --------------- 1,825 $5.82 6/28/06 1,825 $5.43 6/28/06 1,825 $12.10 6/28/06 24,000 $12.66 12/28/06 4,000 $14.68 12/28/06 Linda Stern has direct beneficial ownership of 100,305 shares of E-Z-EM Common Stock that were held by her and Howard Stern as joint tenants with right of survivorship as of the date of his death. In addition, as executor of the H. Stern Estate, Linda Stern is deemed to share beneficial ownership of all of the shares of E-Z-EM Common Stock beneficially owned by the H. Stern Estate, for total beneficial ownership of 1,981,279 shares. Such shares represent 18.2% of the outstanding shares of E-Z-EM Common Stock. The percentage beneficial ownership of Linda Stern and the H. Stern Estate set forth in this Item 5(a) are based on 10,896,374 shares of E-Z-EM Common Stock, inclusive of the options set forth in the above table, outstanding as of May 18, 2006. (b) Linda Stern has sole voting and dispositive rights with respect to the 100,305 shares of E-Z-EM Common Stock she owns directly. The H. Stern Estate and Mrs. Stern share the voting and dispositive rights with respect to the 1,880,974 shares of E-Z-EM Common Stock owned directly by the H. Stern Estate. Item 6 Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer. Item 6 of the Statement is hereby amended by adding the following at the end thereof: On May 18, 2006, Mrs. Stern entered into a Rule 10b5-1 sales plan with Goldman, Sachs for the sale of shares of E-Z-EM Common Stock.
