ITEM 5.  OTHER EVENTS
-------  ------------

CHANGE OF CORPORATE NAME

         On April 24, 2000 Stac Software, Inc. (the Company) changed its name
from Stac Software, Inc., to Previo, Inc. by merging a wholly-owned subsidiary
of the Company, Previo, Inc., with and into the Company pursuant to section 253
of the Delaware General Corporation Law. The sole purpose and effect of the
merger was to effect the name change. In conjunction with this name change the
Company changed its NASDAQ trading symbol from STAC to PRVO. The Company
continues to be listed on the NASDAQ stock market.

         The Company's name change is reflective of the Company's corporate
repositioning, away from back-up and disaster recovery products and into the new
e-Support market. Previo has assumed all of Stac Software's financial and
technological resources for use in the execution of its new e-Support business.

         A copy of the press release issued by the Company announcing the name
change, dated as of April 24, 2000, is attached hereto as Exhibit 99.1. In
addition, a copy of the Certificate of Ownership and Merger which was filed with
the Delaware Secretary of State to effect the name change is attached hereto as
Exhibit 99.2.
