Computer Associates International, Inc. (CA) is continually working to improve our software and services to best meet the needs of our customers. With CA's recent announcement of the general availability of AllFusion Model Navigator 4.1.4 SP1, we would like to take this opportunity to review the support schedule for currently supported releases of AllFusion Model Navigator.

With the availability of AllFusion Model Navigator 4.1.4 SP1, support for Release 3.5.2 is now scheduled to be discontinued as of September 30, 2005. If users are using other AllFusion Modeling products they must also upgrade to the current version (4.1.4 SP1), as these products must be kept in synch. Also, upgrades to our next product release (post 4.1.4) will require customers running 4.1.4 first, as no direct upgrade path will exist from 3.5.2.

If you have not yet upgraded to AllFusion Model Navigator 4.1.4 SP1, we urge you to do so as soon as possible so you can take full advantage of the latest new features and enhancements this release has to offer. For additional information on AllFusion Model Navigator, please visit our support pages at https://support.ca.com.

CA would like to help make your upgrade to the latest release of AllFusion Model Navigator as straightforward and successful as possible. Therefore, to assist you we are offering the following:

• A no-charge upgrade from AllFusion Model Navigator 3.5.2 to AllFusion Model Navigator 4.1.4 SP1 for any customer with an active maintenance contract.



• Publication of documents to help prepare you for your upgrade to AllFusion Model Navigator 4.1.4 SP1. Those documents can be viewed at https://support.ca.com.
