SECURITIES AND EXCHANGE COMMISSION WASHINGTON, D.C. 20549 -------------------- FORM 8-A/A AMENDMENT NO. 1 FOR REGISTRATION OF CERTAIN CLASSES OF SECURITIES PURSUANT TO SECTION 12(b) OR (g) OF THE SECURITIES EXCHANGE ACT OF 1934 DURA PHARMACEUTICALS, INC. (Exact name of registrant as specified in charter) DELAWARE 000-19809 95-3645543 (State of incorporation (Commission (IRS Employer or organization) File Number) Identification No.) 7475 Lusk Boulevard, San Diego, California, 92121 (Address of principal executive offices) Registrant's telephone number, including area code: (619) 457-2553 Securities to be registered pursuant to Section 12(b) of the Act: NONE (TITLE OF CLASS) Securities to be registered pursuant to Section 12(g) of the Act: PREFERRED STOCK PURCHASE RIGHTS (Title of Class) Item 1. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED. On December 10, 1998, Dura Pharmaceuticals, Inc. (the "Company") amended its Rights Agreement, dated May 21, 1998 (the "Rights Plan"), to eliminate those provisions that require that certain actions may only be taken by "Continuing Directors." This Amendment to the Rights Plan was made in response to the Delaware Court of Chancery's recent decision in CARMODY V. TOLL BROTHERS, INC. In the view of the Company's Board of Directors, based on advice of counsel, the TOLL BROTHERS decision has cast doubt on the legality under Delaware law of "Continuing Directors" provisions, also referred to as "dead-hand" provisions, in many existing shareholder rights plans. Although the opinion related to the denial of a motion to dismiss an action challenging the "Continuing Directors" provision and not an opinion addressing the actual validity of the provision under Delaware law, the Delaware court stated that a "Continuing Directors" provision was open to challenge under Delaware law on both statutory and fiduciary grounds. A "Continuing Directors" provision provides that outstanding rights can only be redeemed by "continuing directors," which is generally defined to mean directors who were members of the board at the time the Rights Agreement was adopted and any other person who subsequently becomes a member of the board if such person's nomination for election to the board was recommended or approved by a majority of the continuing directors. While the Company's Rights Plan differs in significant respects from the plan considered in the TOLL BROTHERS case, particularly as regards to the "Continuing Directors" provisions thereof, the Board of Directors believes the disputed validity of these provisions under the TOLL BROTHERS opinion warrants action to amend the Rights Plan. The Form of First Amendment to the Rights Agreement is attached hereto as Exhibit 1 and is incorporated by reference herein. Item 2. EXHIBITS. 1. Form of First Amendment to the Company's Rights Plan.
