ORINDA and PALO ALTO, Calif., December 19, 2000

Dantz Development Corporation and Hewlett-Packard Company (NYSE: HWP) today announced that Dantz' Retrospect® Backup supports HP Ultrium Linear Tape-Open (LTO) drives, which were introduced in November. The currently shipping versions of Dantz' Retrospect Backup software for Microsoft Windows 95/98/Me/NT/2000 and Apple Macintosh already support HP's high-performance Ultrium drives. By employing custom device drivers fully optimized for LTO technology, Retrospect is able to support HP's powerful drives immediately.

With a storage capacity of 200* gigabytes (GB) per cartridge and the ability to stream data at 30* MB per second, HP's Ultrium tape drives provide storage administrators with the power and reliability required to protect the rapidly increasing quantity of critical data on today's networks.

"Retrospect delivers outstanding performance with HP's Ultrium tape drive," said Craig Isaacs, vice president, sales and marketing, Dantz Development. "Customers are impressed by the high throughput and capacity of Retrospect and Ultrium. Retrospect Backup software, with powerful IncrementalPLUS™ technology, reliable Snapshot restores, and intelligent notebook backup, is an excellent match for HP's Ultrium drives."

"With Retrospect Backup, HP's high-performance tape solution can meet customers' entire backup and archiving needs," said Jack Trautman, general manager, HP Data Protection Organization. "HP is committed to building relationships with premier software vendors such as Dantz to ensure the successful adoption of LTO technology."

* All capacities and transfer rates assume a 2:1 data compression ratio.
