West Pharmaceutical Services Issues Statement on Exubera

Lionville, PA October 18, 2007 – West Pharmaceutical Services, Inc. (NYSE:WST) today provided comments related to Pfizer, Inc.’s announcement that it has decided to discontinue marketing the Exubera Inhalable Insulin product, returning the marketing rights to The Company’s customer, Nektar, Inc. The Company’s Tech Group is one of two companies that produce the Exubera inhalation device for Nektar.

“We were surprised and disappointed by Pfizer’s announcement today and are in the process of evaluating its impact on The Company,” said Donald E. Morel, Jr. Ph.D., The Company’s Chairman and Chief Executive Officer “The actual effects on our business will depend on how Nektar decides to proceed in the wake of this change. We will continue to work with and support Nektar as they evaluate their options.”

The Company’s investments related to the Exubera project include approximately $15 million of current assets and production facilities, which it believes are fully recoverable, and approximately $13 million of intangible assets. Pfizer’s decision is not expected to impact the Company’s results for the third quarter ended September 30, 2007 or its earnings per share guidance for the full year of $2.27 to $2.37 per diluted share, excluding, as previously disclosed, discrete tax items and now excluding the effects of any impairment to its intangible assets associated with the Exubera business. The potential for an asset impairment will be evaluated based on information, as it becomes available, concerning Nektar’s plans for Exubera and for the Company’s role in those plans.

The Company will provide any further updates on this situation and to discuss the results of operations and its business outlook in its third quarter 2007 earnings announcement and analyst call, which are scheduled for November 1, 2007.
