Adaptec Continues Cost Cutting Actions

MILPITAS, Calif., - September 9, 1998 - Adaptec, Inc. today announced three
strategic alliances that the company says will "Leverage long-term technology
development and reduce operating expenses." Approximately 200 Adaptec jobs will
be affected by these actions, but about 30% of those are expected to move to the
newly created alliances.

Alliances will be formed with Jaycor Networks Inc. and Chaparral Technologies
Inc. Adaptec's Satellite Networking Group will be spun off to create an
independent company called BroadLogic, Inc.

"The actions taken today are designed to return us to increased profitability,"
said Larry Boucher, Interim CEO at Adaptec. "Focusing Adaptec's business is the
most important objective of the company right now, and these moves put us in
position to achieve that. We are committed to allocating resources to the
products and technologies that are expected to maximize shareholder value."

"What this means is a concentration on our traditional strengths, such as server
and workstation I/O, but also renewed energies directed at growth areas such as
CD-R software, RAID solutions and networking products," Boucher continued.

Employees principally affected by the layoffs are located in Adaptec's Fibre
Channel Products Group and External Storage Solutions Group. Since April,
Adaptec has reduced its workforce by approximately 25%.

Fibre Channel and External Storage Alliances

Adaptec has signed an LOI (letter of intent) to form a strategic alliance with
Jaycor Networks Inc., (JNI) a San Diego-based fibre channel company. Adaptec
will transfer certain technologies and assets to JNI in return for an equity
stake in JNI. Adaptec and JNI will enter into joint manufacturing and sales
relationships to support current customers and expand the market for fibre
channel products.

The company also announced signing an LOI to form a strategic alliance with
Chaparral Technologies Inc. (CTI), a private Longmont-based multimedia tape
storage solutions company. Adaptec will receive an equity stake in CTI in
exchange for the transfer of certain external storage technologies.

Financial terms of both agreements were not disclosed. The companies expect to
complete the transactions as early as October 1, 1998.

Satellite Networking Spinoff BroadLogic Formed

In a separate news release issued today, Adaptec also announced it has completed
the BroadLogic Inc., satellite networking spinoff (see related Business Wire
release). BroadLogic will be based in Milpitas, and will receive certain Adaptec
products and technology for the emerging Satellite-PC communications
marketplace.

"Through the alliances with JNI and Chaparral Technologies, as well as the
BroadLogic spinoff, we are leveraging Adaptec's longer term emerging
technologies and businesses, such as fibre channel, external storage and
satellite networking, for success in the future," said Boucher.

"Shorter term, these actions will reduce operating expenses and increase
profitability, while maintaining a competitive position in technologies that may
have future revenue possibilities," said Boucher.
