Pursuant to Rule 12b-15 of the Securities and Exchange Act of 1934, as amended, this amendment to the Current Report on Form 8-K amends the Current Report on Form 8-K filed on February 4, 1997. On January 23, 1997, the Board of Directors of Lam Research Corporation (the "Company") adopted a shareholder rights plan, as set forth in the Rights Agreement (the "Rights Agreement") entered into between the Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent. Pursuant to the Rights Agreement, one right ("Right") will be issued for each share of common stock, par value $0.001 per share, of the Company outstanding as of the close of business on January 31, 1997. Each of the Rights will entitle the registered holder to purchase from the Company one one- thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.001 per share, at a price of $250. The Rights generally will not become exercisable unless and until, among other things, any person acquires beneficial ownership of 15% or more of the outstanding stock. The Rights are generally redeemable at $0.001 per Right at any time until 10 business days following a public announcement that a 15% or greater position in the Company's common stock has been acquired. The Rights will expire, unless earlier redeemed or exchanged, on January 31, 2007. A description of the Rights is set forth in Exhibit C to the Rights Agreement, a copy of which is incorporated herein by reference as Exhibit 4.1. On January 23, 1997, the Board of Directors of the Company also adopted a number of amendments to the Company's Bylaws (the "Bylaw Amendments"). The Bylaw Amendments provide, among other things, that special meetings of stockholders may be called only at the direction of the Board of Directors, the chairman of the board or the president of the Company. The Bylaw Amendments also establish an advance notice procedure for the nomination, other than by or at the direction of the Board of Directors, of candidates for election as directors as well as for other stockholder proposals to be considered at annual meetings of stockholders. The Bylaw Amendments further provide for the Board of Directors to fix a record date for the Company to determine the stockholders entitled to consent to corporate action in writing without a meeting. The Bylaw Amendments make additional provisions for cumulative voting at the election of the directors of the Company and prompt special board meetings. Certain of the provisions of the Bylaw Amendments may have the effect of delaying or deferring a change in control of the Company. A copy of the Restated and Amended Bylaws of the Company, incorporating all Bylaw Amendments, is incorporated herein by reference as Exhibit 3.1. Item 7. Financial Statements and Exhibits.
