site and listen to presentations outlining Plexus' global vision and future
regional plans.

The Oradea site team will continue to expand in the coming months. The
site began production in July 2009 and it now offers Plexus' customers full
turnkey solutions including printed circuit board assembly,
system/higher-level assembly, test and inspection solutions, process control,

and believe that the Oradea operation will significantly strengthen our
customer service offering in Europe. We also believe that the Oradea facility
will provide our global customers with a lower total-cost European solution,
particularly for products with European end-markets. In addition, we believe
it will enable us to partner with European-based OEMs seeking a global EMS

periods which are not yet completed, are forward-looking statements that
involve risks and uncertainties. These risks and uncertainties include, but

particularly in view of current economic conditions; the effects of the
volume of revenue from certain sectors or programs on our margins in
particular periods; our ability to secure new customers, maintain our current
customer base and deliver product on a timely basis; the risks relative to
new customers, including our recently announced arrangements with The
Coca-Cola Company, which risks include customer delays, start-up costs,
potential inability to execute, the establishment of appropriate terms of
agreement, and the lack of a track record of order volume and timing; the
risks of concentration of work for certain customers; our ability to manage
successfully a complex business model; the risk that new program wins and/or
customer demand may not result in the expected revenue or profitability; the
fact that customer orders may not lead to long-term relationships; the
weakness of the global economy and the continuing instability of the global
financial markets and banking system, including the potential inability on
our part or that of our customers or suppliers to access cash investments and
credit facilities; material cost fluctuations and the adequate availability
of components and related parts for production, particularly due to sudden
increases in customer demand; the effect of changes in the pricing and
margins of products; the effect of start-up costs of new programs and
facilities, including our recent and planned expansions, such as our new
facilities in Hangzhou, China and Oradea, Romania; the adequacy of
restructuring and similar charges as compared to actual expenses; the risk of
unanticipated costs, unpaid duties and penalties related to an ongoing audit
of our import compliance by U.S. Customs and Border Protection; possible
unexpected costs and operating disruption in transitioning programs; the

Mexico, changes in oil prices, epidemics, terrorism and war in the Middle
East); the impact of increased competition; and other risks detailed in the
