Key Customer Letter Template

To Our Valued Customer:

I have some exciting news to share with you: Arch has announced that it will merge with Metrocall Holdings, Inc. (Metrocall), a leading paging and wireless messaging company. The combined company will be one of the largest wireless communications companies in the United States with operations, network coverage and customer service throughout North America.

The combined entity will be stronger both financially and operationally than either Arch or Metrocall as stand-alone companies, creating a wireless communications leader that will be well-positioned to take advantage of future opportunities in wireless messaging.

The merger provides several significant advantages for our customers, including:

In short, the combined company will have the size, breadth and coverage to compete head-to-head with all other wireless communications providers. Customers also will benefit from the greater resources of a financially stronger company. Under terms of the merger agreement, the new entity will gain enhanced financial flexibility as a result of substantial cost synergies. What is more, the resources of the combined company will allow us to keep our customers well ahead of the technology curve and provide them with the latest wireless messaging products.

The company also will take on a new name, yet to be determined.

This is an exciting time in the industry – advances in technology, particularly with regard to the Internet, mean your pager and messaging device are more valuable and useful tools than ever. With this merger, we are excited to be at the forefront of these changes and look forward to using our new resources and technological capability to benefit you, our customer. I hope you share our enthusiasm for the merger and our anticipation of the new possibilities in wireless messaging created by this union.

While the merger is expected to close sometime later this year, our experienced transition team will ensure that the integration of Arch’s and Metrocall’s operations is seamless for our customers. However, should you have any questions or concerns during the transition period, please do not hesitate to call [name] at [number] at any time.

Sincerely,
