Dear Colleagues,

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

I am delighted to inform you of an important new development that will set the stage for new growth and exciting opportunities for 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. The top management of Meadville will remain closely involved with the newly combined business, especially the Asia operations. With this business combination (expected to complete in the first quarter of 2010), the Tang family will become a substantial shareholder of TTM.

I and the management team are confident that this development will provide significant growth opportunities and synergies from business integration with 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 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 can fully leverage our technology specialization and cross selling synergies to further enhance our offerings to existing customers while exploring opportunities with potential new ones.

Over the past 24 years, we have worked hard to become one of the leading players in the high-end PCB market here in the Asia Pacific region. Thanks to all your dedication and expertise. Through which we have been able to build good reputation and excellent track records with our customers. The current management team will remain in place and continue to work closely with you, and we will continue to develop our existing relationships with our customers and business partners as before.

I strongly believe that our enhanced competitiveness and strengthened global presence will enable us to capture more opportunities and create stronger partnerships which can satisfy the needs of our employees, customers and shareholders. The enlarged platform will also provide prospects for career growth and development for all of you, whether in Mainland China, Hong Kong or the U.S.

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

We earnestly look forward to our integration with TTM and hope we can all work hand-in-hand to welcome this new stage of our company’s development. If you have any further questions, please feel free to let me know.

Yours sincerely,

Tang Chung Yen, Tom
Executive Chairman and Group Managing Director
