Products indicates that the Products do not conform to the requirements of this
Agreement, Hon Hai will not ship such Products to Brocade until such
nonconformity has been cured and only Products meeting the conformance criteria
may be shipped. This does not limit Brocade's right to perform additional
acceptance testing at Brocade's facilities.

         7.5      Failure to Inspect. Notwithstanding anything to the contrary
contained in this Agreement, inspection or failure to inspect the Products upon
Delivery will not affect Brocade's rights under the warranty provisions of this

however, that Hon Hai will provide prompt written notice thereof to Brocade to
enable it to seek a protective order or otherwise prevent such disclosure and
will cooperate with Brocade in seeking such protective order.

4.0      PROCEDURE

4.1      VALUE PROPOSITION

4.1.1    The Brocade supply chain value proposition is to establish supplier
         partnerships characterized by the following:

                  -    Open and honest communication

                  -    Strong "values based" management

                  -    On-time delivery of quality products

                  -    End user customer focus

                  -    Timely data driven decision making

                  -    Mutual respect and responsiveness

                  -    Ongoing mutual total life cycle cost reduction

4.1.2    We believe that relationships with these characteristics will enable us
         to establish a world class supply chain management system and provide
         products and services that consistently meet or exceed our customer's
         requirements.

[FLOW CHART]

4.1.3    We believe that everyone in a supply chain is a customer for the work
         done by an "upstream" internal employee or external supplier. As such,
         you have a right to expect good work from them and an obligation to
         deliver work of high caliber to your internal and/or external customer.

4.6.2    Suppliers are expected to initiate and/or participate in periodic value
         engineering efforts to reduce the current and future Brocade cost of
         goods sold (COGS). The timing and content of this activity shall be
         determined on a [*] basis.

4.7      AUTHORIZED VENDOR LIST (AVL)

4.7.1    Contract manufacturers and other partners who supply critical
         components to Brocade must use Brocade's AVL, as required. Notification
         of this requirement will be made in advance.

4.7.2    Brocade will consider AVL change recommendations from any supplier.
         Change requests must be approved in writing by Brocade prior to
         implementation. This is typically done through Brocade's Agile Document
         System.

4.7.3    Brocade reserves the right to [*] or [*] at no additional cost of any
         materials supplied with [*] content. This will be considered a serious

4.10     PRODUCT INSPECTION / PROCESS AUDITING

4.10.1   Brocade reserves the right to conduct [*] product inspection and/or
         process audits of supplier facilities engaged in producing supplied
         parts or Brocade final products. These activities would be conducted
         with [*] of the respective supplier. Discrepancies found during these
         audits will result in a Corrective Action Request (CAR) (see Paragraph
         4.12 below.)

4.10.2   Brocade also reserves the right to conduct source inspection at the
         supplier site. This inspection process, if implemented, would typically
         include the following activities:

                  -   Inspection of in process and/or finished product against
                      all appropriate workmanship standards.

                  -   Acceptance sampling in accordance with ANSI Z1.4
                      (supercedes Mil Std 105), Single Sampling Plan for 1% AQL,
                      Level II, normal inspection level.

                  -   As an example, a random sample of 13 units would be
                      inspected for critical workmanship attributes from a lot
                      of 100 units. The lot would be accepted with zero defects
                      found and rejected with one or more defects found. The
                      supplier would be responsible to conduct a 100% screen of
                      the entire lot for the defective attribute and re-submit
                      the lot for another sample inspection.

                  -   Reduced inspection would occur when production is at
                      steady state, ten consecutive lots pass at normal
                      inspection levels, and the total number of defects in the
                      sample from those ten lots are equal to or less than the
                      applicable number given in ANSI Z1.4. Acceptance of five
                      additional lots at reduced level would qualify the part
                      number for dock-to-stock. Conversely, if two of five
                      consecutive lots were rejected, a tightened inspection
                      would be conducted until five consecutive lots were
                      accepted. At that point, the part would start the
                      qualification process over at the normal inspection level.

4.10.3   Details of the source inspection process and qualification standards
         will be further defined and agreed upon prior to implementation with
         selected suppliers.

4.11     RETURN MATERIAL AUTHORIZATION (RMA) PROCESSING

4.11.1   Brocade will contact suppliers with RMA requests via telephone, e-mail
         and/or fax, depending upon the specific arrangements made.

4.11.2   Unless otherwise specified, suppliers shall provide RMA numbers to
         Brocade within [*] from receipt of the request.

4.11.3   Suppliers shall repair or replace the defective part within [*] of
         receipt of the defective product.

4.11.4   Suppliers shall maintain records of all RMA requests and provide
         in-process and completion status of Brocade RMA's.

4.12     CORRECTIVE ACTION REQUESTS (CARS)

4.12.1   Brocade will issue a Corrective Action Request (Appendix B) whenever a
         discrepant product or unsatisfactory supplier process condition is
         discovered. The CAR Form may be transmitted to the supplier via e-mail
         or fax.

4.12.2   Unless otherwise specified, suppliers shall acknowledge receipt and
         provide a preliminary assessment and immediate corrective action of the
         discrepancy within [*]) of receipt. Unless otherwise specified, the
         preventative measures shall be completed and the documentation
         submitted no later than [*] of a CAR receipt.
