    -  Simplifies enterprise SAN deployment by combining high port density with
       exceptional scalability, performance, reliability, and availability

    -  Delivers industry-leading port density with up to 128 ports in a single
       14U enclosure and up to 384 ports in a single rack, facilitating
       manageable SAN fabrics composed of thousands of ports

    -  Meets enterprise-level availability requirements with redundant, hot-
       pluggable components, no single points of failure within the switch, and
       non-disruptive software upgrades

    -  Supports emerging storage networking technologies with a unique
       multiprotocol architecture

    -  Provides 1 Gbit/sec and 2 Gbit/sec operation today with seamless
       extension to 10 Gbit/sec in the future

    -  Employs Brocade Inter-Switch Link (ISL) Trunking to provide a high-speed
       data path between switches

    -  Leverages Brocade Secure Fabric OS to help ensure a comprehensive
       security platform for the entire SAN fabric

HIGH-PORT-DENSITY, MULTIPROTOCOL
CORE FABRIC SWITCH

As the industry's first 2 Gbit/sec enterprise-level switch, the Brocade(R)
SilkWorm(R) 12000 Core Fabric Switch provides unprecedented levels of
availability, scalability, manageability, and security for open enterprise
storage applications. Possible configurations range from a 32-port switch to a
dual 64-port switch in a single enclosure that provides "pay-as-you-grow"
scalability.

Based on the Brocade Intelligent Fabric Services Architecture, the SilkWorm
12000 provides a reliable foundation for high-performance core-to-edge SANs that
leverage proven core backbone networking methodology. In addition, multiple
SilkWorm 12000 switches can be interconnected at the core to form enterprise SAN
fabrics capable of supporting thousands of hosts and storage devices (see Figure
1).

The SilkWorm 12000 provides higher levels of performance and availability than
director-class switches while supporting a more intelligent and scalable
networked storage model. Moreover, the SilkWorm 12000 is designed to integrate
with heterogeneous environments that include multiple operating systems such
as Windows NT, UNIX, Linux, Solaris, AIX, and others. As a result, organizations
have the flexibility to build cost-effective and easy-to-manage enterprise SAN
fabrics. These capabilities make the SilkWorm 12000 ideal for mission-critical
business continuance applications such as LAN-free backup, remote mirroring,
data replication, and high-availability clustering.

HIGH AVAILABILITY THROUGHOUT
THE FABRIC

The core-to-edge SAN model features redundancy within the core fabric switch as
well as a high-availability network approach for the entire fabric. Combining
the proven reliability of the SilkWorm family with enterprise-level availability
features, the SilkWorm 12000 provides a SAN fabric with built-in redundancy and
no single point of failure. This infrastructure is capable of delivering overall
system availability greater than 99.999 percent--the "five nines" of
availability. Other key availability features include:

- Fabric Shortest Path First (FSPF) traffic rerouting

- Dual-redundant control processors

- Redundant, hot-swappable components

- Redundant power and cooling subsystems

- Non-disruptive software upgrades

INDUSTRY-LEADING PERFORMANCE

The SilkWorm 12000 is designed to provide high-performance switching at the core
of large SANs. All external Fibre Channel ports can operate at 1 and 2 Gbit/sec
per port (inbound and outbound) at distances up to 10 km. In addition,
auto-sensing and speed matching of data traffic ensures interoperability between
1 and 2 Gbit/sec devices. With Brocade Extended Fabrics software and Dense Wave
Division Multiplexing (DWDM) technology, ISLs can span up to 100 km over
Metropolitan Area Networks (MANs)--extending SAN connectivity without
significantly inhibiting performance.

To provide even higher performance in the core, Brocade ISL Trunking technology
combines up to four ISLs between a pair of switches into a single, logical
high-speed trunk running at up to 8 Gbit/sec (see Figure 2).

INTELLIGENCE WITHIN THE SWITCH

To improve security and manageability, Brocade Frame Filtering intelligence is
built directly into the SilkWorm 12000 ASIC technology. This design will enable
new capabilities such as hardware-enforced zoning based on World Wide Name
(WWN), Logical Unit Number (LUN), or protocol. Organizations can also use
Brocade Advanced Performance Monitoring to improve end-to-end performance
analysis on a fabric-wide basis. This optional feature helps reduce storage
costs by enabling improved SAN performance tuning, resource optimization, and
administrator productivity.

OPEN SAN MANAGEMENT

The SilkWorm 12000 simplifies management by networking both core and edge
switches under Brocade Fabric OS, the embedded real-time operating system. In
addition to centralizing management, this design enables heterogeneous device
connectivity, automatic data routing and rerouting, self-healing capabilities,
and scalable connectivity. Moreover, the Brocade Fabric Access API enables
software vendors to develop feature-rich management applications that leverage
the distributed intelligence of Brocade SANs.

SEAMLESS UPGRADES, COST-EFFECTIVE MIGRATION, AND INVESTMENT PROTECTION

To help protect existing technology investments, the SilkWorm 12000 provides a
seamless upgrade path and backward and forward compatibility with SilkWorm
entry, midrange, and port aggregation offerings. As SAN technologies evolve, the
SilkWorm 12000 architecture is designed to integrate with emerging storage
networking protocols such as FICON, iSCSI, FC-IP, and InfiniBand. The current
design is extendable to future 10 Gbit/sec technologies with a switch module
upgrade rather than a forklift upgrade of the chassis.

<PAGE>

A NEW LEVEL OF SAN SECURITY

The SilkWorm 12000 supports Brocade Secure Fabric OS, the most comprehensive SAN
security architecture available. Based on state-of-the-art networking security
technology, this architecture addresses a wide variety of vulnerabilities
within the SAN fabric. Advanced security features provide powerful tools for
securing SAN access and supporting mission-critical applications. In addition,
software- and hardware-enforced Brocade Zoning helps secure data by preventing
unauthorized access.

SUPERIOR RELIABILITY, AVAILABILITY, AND SERVICEABILITY

Enterprise-level SilkWorm 12000 reliability features include the following:

- Redundant control processors provide continuous performance during failovers
  and enable non-disruptive firmware upgrades.

- Continuous monitoring of environmental components helps reduce service costs.

- Power-On Self-Test (POST), online/offline diagnostics,and per-port statistics
  enable administrators to monitor ports and diagnose problems without
  disrupting switch operations.

- Error detection and fault isolation facilities automatically disable failing
  ports and restart them when the problem has been resolved.

INTELLIGENT SAN MONITORING

To simplify SAN monitoring and maintenance, the SilkWorm 12000 provides the
following functions:

- Fabric OS enables value-added Brocade SAN fabric monitoring and management
  applications.

- Industry-standard Management Information Base (MIB) support enables SNMP-based
  interfaces to access switch information.

- Network administrators can manage switch configurations through a command line
  interface or Brocade WEB TOOLS.

The purpose of this Quality/Reliability Requirements Document is to establish an
understanding and agreement between Hewlett-Packard (HP) and Seller with regard
to quality and reliability expectations and responsibilities. The terms Supplier
and Seller are used interchangeably in this Quality/Reliability Requirements
Document.

It is HP's objective to receive Product of the highest possible quality and
reliability with the lowest cost of ownership. The Product must consistently
meet or exceed the requirements of this document and the individual
specifications applicable to each Product. It is HP's expectation that Supplier
shall strive to ship defect-free, fully tested Product as measured at the first
operational test at HP. Repaired units are subject to the same Product
Specifications as when originally shipped.

HP's objective is to work in close cooperation with Supplier to resolve any
quality issue, and expects the Supplier to work diligently to resolve any
quality issue.

2.      DEFECTIVE PRODUCT:

HP shall inform Supplier of any units or lots that fail, and provide Supplier
with yield percentages. Defective units or lots will be shipped to Supplier's
facility as instructed by Supplier. Supplier shall test and verify all failed
units, and provide the data of failure symptoms observed or NTF (No Trouble
Found), on all units returned from HP worldwide manufacturing sites.
