2. Hewlett-Packard's Product Requirements

2.1 SOURCING MATERIAL AS LOGICAL UNITS

All material shall be sourced as individual logical units as defined in section
3. A logical unit is one that will be consumed as a single item within a single
process area or not consumed within the process area and can be set aside
without impacting the integrity of the end product. See section 3 for definition
and declaration of consumable and non-consumable material.

All logical units must be labeled (human readable and 3x9 barcode for scanning)
with a part number, serial number (if applicable) and quantity (if shipped in
bulk). See bar code information for more details. Individual part labeling is
applicable to all parts except when individual labeling is impractical (e.g.
screws, nuts, bolts, etc.).

ESD sensitive parts and material are to be packaged and labeled per industry
standards.

Shipping cartons shall not contain mixed logical units. Each shipping carton may
contain a maximum of one purchase order line item or part number.

2.2 BAR CODE REQUIREMENTS

          -    The bar code symbol bar shall be Code 39 (also known as "Code 3
               of 9") as specified by the AIM Uniform Symbology Specification
               Code 39.

          -    The symbol bar shall start with a minimum "Quiet Zone" of .25
               inches and an asterisk "Start" character ( * in Code 39) where
               applicable (no adjacent labels). The symbol shall end in the
               asterisk followed again by a minimum .25 inches of "Quiet Zone".

          -    The bar code height shall be .125 inches (minimum).

2.3 POWER CORDS

Power cords have strict sourcing requirements. Power cords may only be sourced
from HP specified vendors and only under the HP part number. No other power cord
shall be considered. Because of these requirements, it is not necessary to
include power cords with the 6400 switch.

PURPOSE

The purpose of this Quality/Reliability Requirements Document is to establish an

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 [ * ]. The product must
consistently [ * ] the requirements of this document and the individual
specifications applicable to each Product. It is HP's expectation that Brocade
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 Brocade to resolve any
quality issue and expects Brocade to work diligently to resolve any quality
issue.

DEFECTIVE PRODUCT:

HP shall inform Brocade of any units or lots that fail, and provide Brocade with
yield percentages. Defective units or lots will be shipped to Brocade's facility
as instructed by Brocade. Brocade 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.

              AMENDMENT NO. 2 -- Rev 8.0 dated 11/07/2001- Tippens

                            BROCADE / HP CONFIDENTIAL

                            EXHIBIT (A-6) (ADDITION)
                    OEM PRODUCT INTEROPERABILITY REQUIREMENTS

This is an ADDITION to Exhibit (A-6) of the Agreement.

Based on the interoperability specifications and FC standards compliance
outlined in EXHIBIT -- A6, the Supplier will make [ * ] the following
heterogeneous switch configurations involving Brocade-3800 and fc-64 products
[ * ] The configurations below assume same host and target connectivity and port
topologies as defined in the test plan referenced in step 1) below. Supported
features are outlined below.

As a correction to the version of EXHIBIT (A-6) appended to the Agreement as of
the Agreement's Effective Date, if the mutually agreed upon configurations
include a switch not manufactured by Supplier, then HP shall supply such switch.

As an update to the version of EXHIBIT (A-6) appended to the Agreement as of the
Agreement's Effective Date, Supplier and HP acknowledge that the 1 Gbit IOP
testing process specified in Exhibit (A-6) was not completed. Supplier and HP
agree that the configurations specified in this Exhibit (A-6) (Addition), for
which configurations the 5 step process below is successfully completed, will be
supported by Supplier. The combination 1Gbit and 2Gbit configurations in this
exhibit will supersede and replace the 1 Gbit configurations specified in
EXHIBIT (A-6).

Below is the agreed upon process required for Supplier to support configurations
containing fabrics with switches not manufactured by Supplier.

1) HP and Supplier define the mutually agreed upon configuration and test
   plan.

2) HP will supply to Brocade detailed test results they have completed.
   Detailed results will include but are not limited to:

          a) [ * ]
          b) [ * ]
          c) [ * ]
          d) [ * ]
          e) [ * ]
          f) [ * ]

3) Based on the detailed HP test results, Supplier will then define what
additional testing is required to satisfy support requirements.

4) HP agrees to supply the non-Supplier manufactured switch equipment contained
in the mutually agreed upon configurations for testing and bug replication. The
non-Supplier manufactured switches will be loaned for the period that Supplier
support is required by HP.

5) Once the tests are passed to HP and Supplier's satisfaction, Supplier agrees
to support the configurations to the levels defined in the Agreement. If HP
requests that Supplier support a configuration that includes non-Supplier
manufactured switches that have not been provided to Supplier for test and bug
replication purposes, then HP agrees Supplier will not be held to the Support
response times defined in the Agreement. If these configurations produce
mutually agreed upon test results, HP and Supplier agree to make commercially
reasonable efforts to meet Support requirements in the Agreement.
