(Commission File No.: 000-51072)

The following communication was provided to The Oregonian for potential use in an article:

We are very excited and optimistic about the scale and growth potential of the FormFactor-Cascade combination. To realize that potential, it is critical that all of the FormFactor and Cascade Microtech operating businesses transition seamlessly through the merger, with no interruption to their ability to make and meet customer commitments to win business. To that end, we do not plan to change the existing Cascade operations structure or factories in Beaverton and Dresden, and are excited about welcoming Cascade employees, including the talented Oregon workforce, to the worldwide FormFactor team.

These statements are based on management’s current expectations and beliefs, and are subject to a number of factors and uncertainties, many of which are beyond FormFactor’s and Cascade Microtech’s control, that could cause actual results to differ materially from those described in the forward-looking statements. These forward-looking statements include, but are not limited to, statements about: future financial and operating results; benefits of the transaction to customers, shareholders and employees; potential synergies and cost savings; the ability of the combined company to drive growth and expand customer and partner relationships; and other statements regarding the proposed transaction.

The following factors, among others, could cause actual results to differ materially from those described in the forward-looking statements: the timing to consummate the proposed merger; failure of the Cascade Microtech shareholders to approve the proposed merger; the terms and availability of the proposed financing arrangements; the risk that a condition to closing of the merger may not be satisfied; failure to achieve regulatory approval or the risk that it is obtained subject to conditions that are not anticipated; the challenges and costs of closing, integrating, restructuring and achieving anticipated synergies; the ability to retain key employees, customers and suppliers; the diversion of management time on merger-related issues; and changes in FormFactor’s or Cascade Microtech’s future cash requirements, capital requirements, results of operations, financial conditions and/or cash flows, and other factors, including those set forth in the most current Annual Report on Form 10-K, Quarterly Report on Form 10-Q and Current Reports on Form 8-K filed by FormFactor and Cascade Microtech with the U.S. Securities and Exchange Commission (the “SEC”), under the caption “Risk Factors” and elsewhere.
