Shire Successfully Completes Tender Offer for New River Shares

BASINGSTOKE, England and PHILADELPHIA, Pennsylvania, April 18 (HSMN NewsFeed) -- Shire plc (LSE: SHP.L ; NASDAQ: SHPGY ; TSX: SHQ ; "Shire" or the "Company") announced today that its wholly owned subsidiary, Shuttle Corporation ("Shuttle"), successfully completed its tender offer for the outstanding shares of common stock of New River Pharmaceuticals Inc. (NASDAQ: NRPH ; "New River"). The offer expired, as scheduled, at 12:00 Midnight, New York City time, on Tuesday, April 17, 2007. As of the expiration of the offer, a total of approximately 35,717,806 shares of New River common stock were validly tendered and not withdrawn (not including shares delivered through notices of guaranteed delivery), representing approximately 96.4% of the outstanding shares of New River common stock. Shuttle has accepted for purchase all shares that were validly tendered during the offer.

Shire intends to complete the acquisition of New River through a short-form merger without a vote or meeting of New River's shareholders, after which New River will immediately become an indirect wholly owned subsidiary of Shire. In the merger, each of the remaining shares of New River common stock (other than shares as to which appraisal rights are properly demanded under Virginia law, if any) will be converted into the right to receive the same $64.00 in cash per share, without interest, that was paid in the tender offer. The merger is expected to occur within the next several days and a subsequent press release will be issued at that time. Following the merger, New River's common stock will cease to be traded on The NASDAQ Global Market.

Notes to Editors


Shire's strategic goal is to become the leading specialty pharmaceutical company that focuses on meeting the needs of the specialist physician. Shire focuses its business on attention deficit and hyperactivity disorder (ADHD), human genetic therapies (HGT), gastrointestinal (GI) and renal diseases. The structure is sufficiently flexible to allow Shire to target new therapeutic areas to the extent opportunities arise through acquisitions. Shire believes that a carefully selected portfolio of products with a strategically aligned and relatively small-scale sales force will deliver strong results.

Shire's focused strategy is to develop and market products for specialty physicians. Shire's in-licensing, merger and acquisition efforts are focused on products in niche markets with strong intellectual property protection either in the US or Europe.
