Javelin Pharmaceuticals, Inc. (NYSE Amex: JAV), a leading developer of novel acute care pain products, commented on the tender offer extension by Hospira, Inc. Hospira, Inc. ("Hospira") announced today that Discus Acquisition Corporation, a wholly owned subsidiary of Hospira ("Discus"), is extending the tender offer to purchase all outstanding shares of the common stock of Javelin Pharmaceuticals, Inc. ("Javelin"). Hospira has indicated that the offering period will be extended to 12:00 midnight, New York City time, on June 2, 2010. Hospira has asserted that the extension of the offering period is permissible under the agreement and plan of merger dated April 17, 2010 among Discus, Hospira and Javelin (the "merger agreement") on the basis that certain of the conditions to Discus's obligation to accept and pay for shares tendered through May 18, 2010, which represent 78.82% of the shares of common stock of Javelin outstanding, were not fully satisfied prior to the expiration of the initial offering period of the tender offer. Javelin believes that, in asserting the failure to satisfy in full any such conditions, Hospira is purporting to rely on information regarding a supply chain issue in the United Kingdom described below. Javelin was notified, on May 14, 2010 by a licensee of commercial rights to Dyloject in the European Union, that an issue has arisen in the UK Dyloject supply chain. Javelin notified Hospira of this matter promptly after being informed. Javelin is not aware of any issue in its supply chain for Dyloject in the United States. Javelin disagrees with Hospira's position under the merger agreement that the conditions to the tender offer have not been fully satisfied and believes that all of the conditions of the tender offer have been satisfied. Javelin continues to honor its obligations under the terms of the merger agreement.
