Dear VALUED CUSTOMER,

Information is the lifeblood of every modern organization. We know that you are working to balance the need to both secure that information and make it available, ensuring its integrity. We believe information integrity provides the most cost-effective, responsive way to keep businesses up, running and growing no matter what.

On December 16, 2004, Symantec Corporation, the world leader in Information Security, and VERITAS Software Corporation, the world leader in Storage Software announced that they have signed a merger agreement. The planned merger is subject to regulatory and shareholder approvals. We currently anticipate closing in the second calendar quarter of 2005.

The combined company will offer you a more effective way to secure and manage your most valuable asset, your information. In addition, as a single company post merger, our objective is to work with you reduce the costs and complexities of managing security and data. And we will provide security and availability across multiple platforms, from the desktop to the data center.

Until the merger closes we will work with you “business as usual” and are committed to continue to deliver the high level of service and support you are accustomed to from our organizations.

Our belief is that customers will receive significant benefit from a company capable of providing end-to-end information security and availability solutions. If you would like more information about the merger immediately and greater details about the benefits of this merger to your organization, please visit www.symantec.com or contact your Symantec account manager.

In closing, we thank you for your business and look forward to establishing an even greater partnership moving forward.

Sincerely,

Thomas Kendra
Senior Vice President, Worldwide Sales
