Item 1. Description of Securities Registered.

     On August 15, 2001 pursuant to a Preferred Stock Rights Agreement (the “Rights Agreement”) between Barra, Inc. (the “Company”) and Mellon Investor Services LLC, as Rights Agent (the “Rights Agent”), the Company’s Board of Directors declared a dividend of one right (a “Right”) to purchase one one-thousandth share of the Company’s Series A Participating Preferred Stock (“Series A Preferred”) for each outstanding share of Common Stock, par value $0.0001 per share, of the Company. The dividend was paid on September 7, 2001, to shareholders of record as of the close of business on that date. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Preferred at an exercise price of Two-Hundred Dollars ($200.00), subject to adjustment, upon the occurrence of certain events.

     On February 12, 2003, the Company’s Board of Directors and the Rights Agent executed an amendment (the “Amendment”) to the Rights Agreement. The Amendment increased the percentage threshold of the Company’s outstanding shares of common stock, from 20% to 25%, that Dr. Andrew Rudd, the Company’s current Chairman of the Board of Directors, may acquire prior to becoming an “Acquiring Person” under the terms of the Rights Agreement.

     Except as expressly amended by the Amendment, the principal terms of the Rights Agreement remain in full force and effect. A copy of the Rights Agreement is attached as an exhibit to the Registration Statement on Form 8-A filed with the Securities and Exchange Commission on August 24, 2001.
