Dear Valued Business Partner,

Subject: Business Combination Between Meadville’s PCB Business and TTM Technologies, Inc.

I am delighted to inform you of an important and exciting new development at Meadville. We have just announced that subject to the closing of the transaction, our PCB business will be combining with TTM Technologies, Inc., North America’s largest PCB manufacturer by revenue and a listed company on NASDAQ. Our Group’s founder and largest shareholder, Mr. Tang Hsiang Chien through his representatives will remain closely involved with the newly combined business. With this business combination (expected to complete in the first quarter of 2010), Mr. Tang will, through his company, become a substantial shareholder of TTM.

TTM is North America’s largest PCB manufacturer and a leading supplier of PCB and backplane assemblies and specializes in the high-end commercial and aerospace / defense markets, including networking and communications infrastructure, computing, industrial and medical markets. The combination of TTM and Meadville’s businesses will create one of the world’s leading PCB business, with strong PCB production and R&D capabilities in both North America and the Asia Pacific region. We will be able to offer an integrated global sales and production solution and with our “global presence, local knowledge” strategy, we will become even more competitive.

At the same time, Meadville’s laminate business will be sold to another company owned by Mr. Tang. Upon completion of the two transactions which are conditional on each other, Meadville proposes to delist from the Hong Kong Stock Exchange.

The new combined business’ global headquarters will be in the U.S. and Asia headquarters in Hong Kong. Please be assured that there will be no changes to our existing management team here in Asia and we will continue to work closely with you as our valued partner. We sincerely appreciate your support and we look forward to continue working with you closely in the future. We will keep you updated on the new developments at Meadville and the new combined PCB business.

Should you have any questions, please do not hesitate to contact Audrey Sim on (+852) 2660 4287 or visit our website at http://www.meadvillegroup.com/announcements.html for more details.

Yours sincerely,

Tang Chung Yen, Tom
Executive Chairman and Group Managing Director
