Commission File No. 000-10761

November 18, 2010

Dear Valued Partner:

We are pleased to announce that Verigy and LTX-Credence, a global provider of focused, cost-optimized ATE solutions, have entered into a definitive merger agreement. We believe the combined company, to be called Verigy, will have the strength and scope to provide an expanded portfolio of innovative test solutions across all semiconductor market segments and a larger service and support network worldwide. We’re excited about the possibilities that the combined company represents.

What You Can Expect Moving Forward

The transaction is subject to the approval of shareholders from both companies as well as customary closing conditions and regulatory approvals. We expect to close the merger in the first half of calendar 2011. Until then, Verigy and LTX-Credence remain two separate companies and will continue to operate as such.

Upon closing, an experienced executive team will oversee the integration. Verigy president and COO, Jorge Titinger, and LTX-Credence president and CEO, David Tacelli, will serve as co-CEOs of the combined company, which will be headquartered in Singapore with U.S. headquarters in Cupertino, California. Verigy chairman and CEO, Keith Barnes, will continue as the chairman of the board of directors of the combined company, and Verigy CFO, Bob Nikl, will continue as CFO.

To facilitate the leadership change, Keith Barnes will transition from Verigy CEO to Verigy chairman of the board of directors as of Dec. 31, 2010, and Jorge Titinger will be promoted to CEO and president. The merger and related proxy filing provide a logical opportunity to accelerate this planned succession. This will allow Keith, as Verigy’s chairman, to focus on the investor community and to work toward successfully closing the merger transaction.

Our Commitment to You

We understand that you may have many questions about this merger. As a result of this announcement, we do not expect any immediate changes to our agreements, purchase orders and/or contracts with you.

Our goal is to make the integration process as seamless as possible. We will work to make decisions as quickly as possible when the transaction closes and to keep you updated on any changes that may affect you.

For more information regarding this announcement, please go to www.Verigy.com, and don’t hesitate to contact your primary Verigy representative.

Thank you in advance for your patience and support as we create our combined company.

Sincerely,

This document contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. These statements are based on management’s current expectations and beliefs and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. The forward-looking statements contained in this document include statements about the ability of the combined company to provide an expanded portfolio of innovative test solutions and a larger service and support network worldwide; expectations for the timing of closing the merger; expectations about the combined company’s leadership and board composition; expectations regarding any immediate changes to agreements, purchase orders and/or contracts; and other statements regarding the proposed transaction.

These statements are not guarantees of future performance, involve certain risks, uncertainties and assumptions that are difficult to predict, and are based upon assumptions as to future events that may not prove accurate. Therefore, actual outcomes and results may differ
