Dear Software Product Services Customer:

Compaq Customer Services wishes to inform you that Compaq Computer Corporation has begun a transition process for the following products:

Compaq has offered these products and related support services under a distribution agreement with InterSystems Corporation since InterSystems acquired DSM in 1995. As of May 31, 1999 Compaq will no longer sell new DSM licenses or enter into new DSM service agreements. If you have a current DSM service agreement, Compaq will continue to provide service through its Customer Support Centers in accordance with the provisions of your maintenance contract until the end of your contract term or through May 31, 2000, whichever is sooner. Warranty customers will receive support throughout their initial warranty agreement.

InterSystems (www.intersys.com) will continue to offer DSM licenses, license upgrades, and 7-by-24 support, as it has since 1995. With thousands of DSM systems in use around the world, InterSystems remains fully committed to DSM.

Please contact InterSystems at +617 621-0600 before the end of your Compaq service contract to arrange for InterSystems support and avoid interruption in service.
