Dear Valued Customer,

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. To further expand our business and to better serve you as our valued customer, we have just announced that subject to the closing of the transaction, our PCB business will combine 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. Its customers include original equipment manufacturers and international electronic manufacturing services companies. Currently, TTM has eight manufacturing operations, seven of which are in the U.S. and one in the PRC.

The combination of TTM and Meadville’s PCB 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 in PCBs, flex and rigid-flex and backplane assembly products as well as providing small volume quick-turn production. With our “global presence, local knowledge” strategy and combined revenue (2008 pro-forma: approximately US$1.35 billion), we will become even more competitive and able to serve you better to your satisfaction.

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.

Please be assured that our existing management team and employees will continue to manage the Asia operation of the combined PCB business and render their very best services to you. We sincerely appreciate your support to Meadville in the past and we are confident that the combination of the two leading PCB businesses will definitely enable us to better meet your needs in the future. We will continue to update you on the new developments and the new combined PCB business.

Should you have any questions, please do not hesitate to contact Kingsley Chau on (+852) 2660 3168 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
