Asyst Technologies Amends Shareholder Rights Plan

Asyst Technologies, Inc. (Nasdaq:ASYT) announced that earlier today its Board of Directors has amended and restated its Shareholder Rights Plan which was adopted on June 25,1998 (the "Prior Plan”). Among other changes, the amended plan extends the current term by 12 months. The amended plan also includes a "qualified offer” provision, under which shareholders can require the Board to redeem the rights under the plan and allow an offer to purchase the Company that meets certain criteria to proceed. The Prior Plan had been scheduled to expire on July 10, 2008. Asyst’s Amended and Restated Shareholder Rights Plan (the "Amended Plan”), effective as of July 9, 2008, is designed to ensure that all of the Company's shareholders continue to receive fair and equal treatment in the event of any unsolicited attempted takeover of the Company and to protect shareholders from partial tender offers, open market accumulations and other potentially abusive or coercive tactics to gain control of the Company without offering an adequate price to all shareholders. As was the case with the Prior Plan, the Amended Plan is not intended to prevent a takeover. Instead, it is intended to encourage anyone seeking to acquire the Company to negotiate with the Company’s Board of Directors prior to attempting a takeover in order to ensure that any takeover reflects an adequate price and that shareholders’ interests are protected. The Amended Plan is intended to continue to enable all of the Company's shareholders to realize the long-term value of their investment in the Company. As a result of the Board's adoption of the Amended Plan, each preferred stock purchase right (a "Right"), which was previously distributed to Asyst’s common shareholders under the Prior Plan, entitles the holder, if and when the Right becomes exercisable, to buy one one-thousandth of a share of Asyst’s Series A Junior Participating Preferred Stock for $12.50. Initially, the Rights will be represented by the Company's Common Stock certificates and will not be exercisable. If any person or group becomes the beneficial owner of 15 percent or more of Asyst’s Common Stock (which, as provided in the Amended Plan, includes stock referenced in derivative transactions and securities), then each Right not owned by such Acquiring Person will entitle its holder to purchase, at the Right's then-current exercise price, shares of Common Stock having a market value of twice the Right's then-current exercise price. In addition, if, after any person has become an Acquiring Person, the Company is involved in a merger or other business combination transaction with another person, each Right will entitle its holder (other than such Acquiring Person) to purchase, at the Right's then-current exercise price, common shares of the acquiring company having a value of twice the Right's then-current exercise price. The Company may redeem the Rights at a price of $0.001 per Right at any time prior to the date on which any person has become an Acquiring Person. In addition, the Amended Plan includes a Qualified Offer provision, which provides that if an offer is made for the Company’s outstanding Common Stock which meets certain pre-determined criteria set forth in the Amended Plan, the record holders of 10 percent of the outstanding Common Stock (other than shares held by the offeror and its affiliates) may after 90 business days direct the Company to call a special shareholders’ meeting to consider a resolution authorizing a redemption of the Rights. If the special meeting is not held within 90 business days of being called or if the holders of a majority of the outstanding Common Stock (other than shares held by the offeror and its affiliates) vote in favor of the redemption of the Rights, then the Company’s Board will redeem the Rights or take such other actions necessary to prevent the Rights from interfering with the consummation of the Qualified Offer. The Amended Plan will continue in effect until the close of business at 5:00 p.m., EDT, on July 8, 2009, unless earlier redeemed or terminated by Asyst, as provided in the Amended Plan. Details of the Amended Plan, including a copy of the Amended Plan, will be filed with the SEC in a Current Report on Form 8-K.
