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.

4.1.4    Sustained quality excellence requires continuous process improvement.
         This means, regardless of how good present performance is, it can
         become even better. "You can manage what you can measure." Align what
         you measure to the individual behaviors you want to support.

4.2      SUPPLIER PARTICIPATION

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.

Products ("Rejection Period"), Brocade [*] may inspect and reject any Product
that fails to meet the Specifications.

         7.2      Rejection. Within the Rejection Period, customers may notify
Brocade of any Product rejections and the reasons therefor. In accordance with
the RMA procedures of Section 11.1, below, Brocade [*] may return rejected or
defective Products to Solectron, [*]. [*] In the event that the returned Product
is defective, Solectron will repair or replace such defective Product, [*].
Solectron will return to Brocade or its customer, as the case may be, freight
prepaid, all repaired or replaced Products within [*] after Solectron's receipt
of the returned Product or within such other time as specified in the SLA. Any
returned Products that have been damaged by misuse, abuse or unauthorized
repair, by or on behalf of the End User, may be treated by Solectron as "out of
warranty" and subject to out of warranty repair charges referenced in Section
8.1 only. Any returned Products, which are not, in fact, defective, may be
returned by Solectron to the End User at [*] expense, pursuant to the terms of
the SLA.

         7.3      Spot Testing. Upon prior written notice to Solectron, and
subject to the confidentiality requirements herein, Brocade or its authorized
representative(s) may conduct spot functional tests of the Products at
Solectron's facility at which Products are being manufactured during Solectron's
normal business hours. The parties will mutually agree upon the timing of such
investigations, which will be conducted in such a manner as not to interfere
with Solectron's operations. If any Products fail any material part of the test
procedure set forth on the Statement of Work, Brocade may reject such Products,
and Solectron will promptly take all steps necessary to correct such failures.

         7.4      Site Inspections. Upon prior written notice to Solectron, and
subject to the confidentiality provisions herein, Brocade[*] will have the right
to perform on-site inspections at Solectron's manufacturing facilities and
Solectron will fully cooperate with Brocade in that regard at mutually agreed
upon times. If an inspection or test is made on Solectron's premises, Solectron
will provide Brocade's inspectors with reasonable assistance at no additional
charge. In the event that any on-site inspection of the Products indicates that
the Products do not conform to the requirements of this Agreement, Solectron
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
Agreement.

8.       Pricing and Payment.

         8.1      Prices. The unit prices to be paid by Brocade for the Products
shall be as set forth on Exhibit A or as otherwise agreed by the parties. Except
as otherwise expressly provided in this Agreement, such unit prices include [*]
for the Products or warranty repair services (as the case may be), any related
deliverable items and packaging for delivery to Brocade. The prices attached to
the Exhibit A will be reviewed on a [*] basis. All payments hereunder will be
paid in U.S. Dollars unless otherwise mutually agreed upon by the parties in
writing. [*]

         8.2      Components Management. Solectron agrees to manage inventory
and purchase materials in a manner that is cost effective. [*]

                  (a)      Cost Reductions. Material cost reductions will be
reviewed and mutually agreed upon by Brocade and Solectron on a [*] basis and

         8.3      Taxes. [*] Where the law permits, Solectron will treat Brocade
as exempt from applicable state and/or local sales tax for Product(s) purchased
pursuant to this Agreement. Where required by state or local law, Brocade will
provide Solectron with a valid reseller's exemption certificate for each taxing
jurisdiction to which Solectron ships Product(s).

         8.4      Invoices. [*] Solectron will submit invoice(s) periodically to
Brocade upon [*] of Product(s). Brocade will pay non-disputed invoices net [*]
after the later of date of [*] of (a) the Products [*], or (b) Solectron's
invoice to Brocade. Payment will not constitute acceptance of the Products by
Brocade. If Brocade requests, and Solectron agrees, that Products or FRUs be
kept in [*], Solectron will invoice Brocade for the Products [*] after the
Products or FRUs enter [*]. Upon [*] for such Products or FRUs that enter

quality assurance program for the Products that is consistent with, and at least
as restrictive as, the terms and conditions listed in Exhibit D.

10.      Engineering Changes.

         10.1     ECOs. Brocade may, upon advance written notice to Solectron,
submit engineering change orders ("ECOs") for changes to the Products. ECOs will
include documentation of the change to effectively support an investigation of
the impact of the engineering change. [*] Solectron will acknowledge the ECO and
report to Brocade within [*] upon Solectron's receipt of the ECO. If the ECO
affects the manufacturing or repair costs of the Products or otherwise affects
the price of the affected Products, the parties agree to negotiate in good faith
an equitable adjustment to the price of the affected Products prior to
implementation of the change. The parties agree that [*] is a reasonable time
period to permit Solectron to evaluate ECO impact regarding potential excess
manufacturing costs and price, if any, and non-recurring costs, if any.
Notwithstanding the foregoing, Brocade may require, from time to time, [*]
implementation of an emergency ECO. In these cases, Solectron will provide
Brocade with a preliminary estimate of the cost impact within [*].

         10.2     No Changes. No changes will be made to the Products without
Brocade's prior written consent and no approved change will be made effective
prior to the date approved by Brocade in writing. Solectron will not change or
modify the processes for the Products without Brocade's prior written consent.
Solectron will reimburse Brocade for all expenses incurred by Brocade to qualify
changes to such materials or processes that are undertaken by Solectron without
Brocade's prior written consent.

11.      Product Repairs and FRUs Supply.

         11.1     Repair Services. Solectron will provide repair services to
Brocade and Brocade-authorized third parties (i) for all in-warranty Products in
accordance with the terms of Sections 14, below, and (ii) [*] for any
out-of-warranty Products and FRUs for a period of [*] from the end-of-life
production of such Products or FRUs by Solectron or a Brocade Vendor. For any
Product or FRU that is returned to Solectron for repair or replacement services,
Brocade will issue a Return Material Authorization ("RMA") number, and will
forward such RMA electronically to Solectron, through Brocade's [*] system. All

favorable due to the [*] of the remaining support period for the FRU(s),
Solectron will assist Brocade in [*] through manufacturing. [*]

12.      Ownership.

         at Brocade's discretion, to products specifically developed for Brocade
         by [*] and other [*].

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.

4.1.4    Sustained quality excellence requires continuous process improvement.
         This means, regardless of how good present performance is, it can
         become even better. "You can manage what you can measure." Align what
         you measure to the individual behaviors you want to support.

4.2      SUPPLIER PARTICIPATION

<PAGE>

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.
