Pfeiffer Vacuum Technology AG / Pfeiffer Vacuum Technology AG Intends to Acquire Alcatel-Lucent's Vacuum Technology Unit "Adixen"

On the Road to Becoming a World Leader in Vacuum

ASSLAR, Germany, November 3, 2010 - Pfeiffer Vacuum Technology AG, Asslar, intends to acquire
Alcatel-Lucent's Vacuum Technology Unit ("Adixen") which is headquartered in
Annecy, France. Negotiations on the purchase of the companies, patents and
licenses belonging to this unit have been largely finalized.

Manfred Bender, Chief Executive Officer of Pfeiffer Vacuum Technology AG,
comments on the envisaged acquisition: "With this move, Pfeiffer Vacuum is
now entering a new dimension of business. We will not only double our sales
revenues, but also significantly increase our market presence. We have always
said we want to enhance our position in backing pumps, and we believe
that the Adixen product portfolio is the perfect fit for us. In addition, we
will expand our international sales and service network and, in particular,
gain better overall access to the high-growth Asian markets." Bender adds:
"We at Pfeiffer Vacuum are dedicated to creating and enhancing value for our
shareholders. Based on the current strong business performance we expect to
generate sales revenues of more than EUR 500 million in the fiscal year
2011.The financial results we announced this morning demonstrate that we were
able to return our EBIT margin to normal, even during the first year of the
Trinos integration. And we are going to show the same strict discipline in
connection with the Adixen integration."

Jean-Yves Guegan, President of Adixen, notes: "The combination of Adixen
and Pfeiffer Vacuum, two leaders in pumping solutions and leak detection
systems, will create a powerful force in the industry. Our portfolio and
talent meshes quite well with that of Pfeiffer Vacuum and will create a
platform to better serve both companies' existing customers as well as drive
growth in overall market share."

Alcatel-Lucent's Vacuum Technology Unit, which does business under the
Adixen brand name, is an acknowledged world leader in vacuum pumps and leak
detectors with a top market position in the field of backing pumps. In fiscal
year 2009, the Adixen unit generated sales revenues of EUR 134 million and a
negative EBITDA of EUR 3 million which was largely attributable to the
general economic crisis. The interim financial statements for the Adixen unit
for the period ended June 30, 2010, record sales revenues of EUR 116 million
and an EBITDA of EUR 14 million.

On the basis of these numbers, sales revenues of approximately EUR 270
million and an EBITDA of approximately EUR 40 million are anticipated for the
entire fiscal year 2010.

The purchase price for this unit will total approximately EUR 200 million
on a debt/cash-free basis and will be fully financed through a bank loan.
Pfeiffer Vacuum intends to reduce a portion of the acquisition financing by
selling treasury shares and through a capital increase from authorized
capital in the amount of up to 10 percent of its share capital. The
supervisory board of Pfeiffer Vacuum consented to the acquisition today.
Prior to the signing of the contract, a hearing of employee councils of the
Alcatel-Lucent group is required. The acquisition is planned to become
effective on December 31, 2010.

Hauck & Aufhauser Investment Banking and Wagram Corporate Finance acted
together as sole financial advisors to Pfeiffer Vacuum on this transaction.
