(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.

Forward-Looking Statements

This communication contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, including with respect to the anticipated timing, completion and effects of the proposed merger between FormFactor and Cascade Microtech. 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. Forward-looking statements may contain words such as “may,” “might,” “will,” “could,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “intend” and “continue,” the negative or plural of these words and similar expressions, and include the assumptions that underlie such statements. 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. All forward-looking statements are based on management’s estimates, projections and assumptions as of the date hereof. No assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do so, what impact they will have on the results of operations or financial condition of FormFactor or Cascade Microtech. Unless

required by law, FormFactor and Cascade Microtech are under no obligation (and expressly disclaim any such obligation) to update or revise their forward-looking statements whether as a result of new information, future events, or otherwise.
