AFX Alternative Fuel Systems

Fuel Systems Solutions, Inc. ("Fuel Systems") (Nasdaq:FSYS) and Alternative Fuel Systems (2004) Inc. ("AFS") (TSX-V:AFX) today announced that AFS Acquisition Co. Inc. (the "Offeror"), a wholly-owned indirect subsidiary of Fuel Systems, took up and accepted for payment 15,704,867 common shares of AFS ("AFS Shares"), representing approximately 83.3% of the outstanding AFS Shares on a fully-diluted basis, pursuant to its previously announced offer to acquire all of the outstanding AFS Shares, including all AFS Shares that may be issued on the exercise of options granted under AFS's stock option plan, at a price of Cdn.$0.50 in cash per AFS Share by way of a formal take-over bid (the "Offer").

By written notice given to the depositary for the Offer, the Offeror has also extended the time for acceptance of the Offer from 5:00 p.m. (Calgary time) on May 17, 2011 to 5:00 p.m. (Calgary time) on May 31, 2011 in order to enable the remaining shareholders to receive prompt payment of the same Cdn.$0.50 per share consideration under the Offer. A notice announcing the extension of the Offer will promptly be mailed to holders of AFS Shares.

Neither the Offeror nor any of its affiliates owned or controlled any AFS Shares prior to the take-up of AFS Shares under the Offer. The purpose of the Offer is to enable the Offeror to acquire (and its direct and indirect parents, IMPCO Technologies, Inc. ("IMPCO") and Fuel Systems, respectively, to indirectly acquire through the Offeror) all of the outstanding AFS Shares. The Offeror intends to acquire all remaining Shares not deposited under the Offer pursuant to a compulsory acquisition or other going private transaction under the Business Corporations Act (Alberta) within approximately the next 30 to 90 days. In connection with a compulsory acquisition or other going private transaction, the Offeror intends to cause AFS to apply for the delisting of the AFS Shares from the TSX Venture Exchange (the "TSXV") and to cease being a reporting issuer under Canadian securities laws.

Following the take-up of AFS Shares under the Offer, all of the directors of AFS resigned and were succeeded by nominees of the Offeror. The AFS board now consists of Matthew Beale, Mark Haskins, Norman Bryan and James Nall.

Full particulars of the Offer are set out in the offer and circular filed by the Offeror (as amended by the notice of extension to be mailed by the Offeror) and the directors' circular filed by AFS. AFS shareholders are urged to carefully read and consider the information contained in these circulars. These documents, as well as copies of the support agreement and lock-up agreements in respect of the Offer, are available on the Canadian Securities Administrators' website at www.sedar.com under AFS's profile.
