                    shall have the right, at any time and from time to time, to
                    request an immediate meeting with Seller, and if a [*] is

                    and Buyer will jointly develop alternatives to resolve any
                    late delivery of the Products, including use of premium
                    routing [*]. Seller will develop recovery plans with new
                    committed due-on-dock dates and communicate such plans to
                    Buyer within [*] business day of missed shipments.

          8.2       Seller shall establish and/or maintain a quality improvement

                    function of the Product or Spares to be purchased hereunder

                    commercially reasonable efforts to ensure that all Products

                    BE RESPONSIBLE TO THE OTHER FOR ANY INCIDENTAL OR
                    CONSEQUENTIAL DAMAGES ARISING OUT OF THIS WARRANTY. HOWEVER,
                    NOTHING HEREIN SHALL BE DEEMED AN ASSUMPTION BY EITHER PARTY
                    OF LIABILITY THAT THE OTHER PARTY HAS IN CONTRACT OR AT LAW,

     13.  TERM OF AVAILABILITY

          13.1      In consideration for Buyer's purchase of any Products or
                    Spares hereunder, Seller grants to Buyer the option to
                    purchase replacement Products and Spares at the last
                    revision level purchased under this Agreement for the period
                    [*] after Seller's formal "End of Life" or "EOL"
                    notification during the term of this Agreement (or the
                    Agreement's termination, as applicable), or for as long as
                    said Products or Spares is made available to any of Seller's
                    other customers, whichever is the later. Buyer shall use
                    commercially reasonable efforts to provide Seller with a
                    forecast for Buyer's anticipated purchases of Products and
                    related Spares for each Product within [*] days of the date
                    of "EOL" notification or the termination of this Agreement,
                    as applicable, and Seller shall make commercially reasonable
                    efforts, to provide Product or Spares in excess of such a
                    forecast.

                    or Spares by giving Buyer [*] months prior written notice,

                    placed by Buyer prior to the expiration of such [*] month
                    period

                    sufficient quantities of Products and/or Spares [*]

                    non-cancellable order and delivery must be scheduled to
                    occur within the above [*] month window. Seller shall use
                    reasonable efforts to delay [*] for the Products until
                    Seller deems necessary to meet Buyer's requested deliveries.

                    Seller shall make commercially reasonable efforts to [*] and
                    [*] for Buyer. Buyer shall pay all reasonable documented
                    costs including, but not limited to material, labor,
                    overhead as charged to Seller by Seller's subcontract
                    manufacturer, and reasonable profit margin. Such cost
                    liability shall be no more than the purchase price for the
                    Products.

          13.3      The parties shall negotiate in good faith the Terms and
                    Conditions of the purchase set forth in Sections 13.1. and
                    13.2 above. However, in no event shall the [*] for Products

                    contrary, may terminate this Agreement and/or any Order

                    shareholders, employees and agents ("Buyer Indemnified
                    Parties") from and against any and all claims, demands,
                    suits, actions, judgments, costs and liabilities (including
                    attorneys' fees) (each, an "Indemnified Loss"), relating to
                    or arising out of any allegation that Products or Spares
                    furnished under this Agreement infringe or violate any U.S.
                    patent issued as of the Effective Date, copyright or trade
                    secret of any third party and shall pay all costs and
                    damages awarded; provided, the foregoing indemnity shall not
                    apply to the extent any such claim is attributable solely to
                    design specifications furnished by Buyer to Seller. If an
                    injunction or exclusion order preventing the use, sale,
                    lease license, or other distribution of the Products or
                    Spares of any part thereof of the Products or Spares results
                    from such a claim (or, if Buyer [*] such an injunction is
                    [*]) Seller shall, at its expense, and at Buyer's request,
                    use commercially reasonable efforts to [*] for Buyer the [*]
                    to [*] the Products or Spares. In the event that Seller
                    cannot [*] for Buyer, Seller shall be deemed to have
                    breached its warranty set forth in Section 11.1 and
                    thereupon Seller shall [*] all such Products and Spares from
                    Buyer at the [*]. The foregoing indemnity obligation shall
                    not extend to any claims of infringement arising out of or

                    by anyone other than Seller without Seller's prior written
                    consent; (ii) a combination of the Products and/or Spares
                    with any third party software or hardware where such
                    combination is the cause of such infringement; (iii) the use
                    of a version of Software other than the then-current version
                    if infringement would have been avoided with the use of the
                    then-current version; and (iv) any design specifications
                    provided by Buyer to Seller. The foregoing sets forth
                    Buyer's sole and exclusive remedy with respect to claims of
                    infringement of third party intellectual property rights of
                    any kind.

                    design specifications provided by Buyer to Seller.

                    obligated to indemnify the other party (the "Indemnified
                    Party") under this Agreement, this obligation is contingent
                    upon the Indemnified Party providing the Indemnifying Party

                    Indemnified Party shall not settle a claim without the
                    Indemnifying Party's prior written approval. The Indemnified
                    Party may participate in any such defense or settlement with
                    counsel of its own choosing at its expense.

          31.2      If any provision or provisions of this Agreement shall be
                    held to be invalid, illegal or unenforceable, such provision

          31.4      Neither party shall export, re-export or otherwise disclose,

          31.6      To the extent the confidentiality provisions set forth in

                    forth in any other confidentiality or non-disclosure
                    agreement between the parties hereto, this Agreement
                    represents the entire agreement with respect to the subject
                    matter hereof and supersedes all prior discussions and
                    agreements between the parties relating to the subject
                    matter hereof. This Agreement can be modified only by a
                    written amendment duly signed by persons authorized to sign
                    agreements on behalf of both parties, and shall not be
                    supplemented or modified by any course of dealing or trade
                    usage. Variance from or addition to the terms and conditions
                    of this Agreement in any Order, or other written
                    notification from Seller will be of no effect. Seller,
                    including its servants, agents and employees, is an
                    independent contractor and not an agent or employee of
                    Buyer. Without limiting the generality of the foregoing,
                    Seller is not authorized to represent or make any
                    commitments of behalf of Buyer, and Buyer expressly
                    disclaims any liability therefore.

     If at any time data from either Seller's or Buyer's control and measurement
     systems indicates that Material quality and/or reliability has fallen below
     the minimum established levels identified in Table 1, corrective action
     shall commence immediately and will continue until the quality and/or
     reliability again meets or exceeds the minimum acceptable level. In such
     event, the following shall be [*] of Seller, as a minimum:

     o  Immediately notify Buyer of the problem, its manifestations, symptoms,
        and an initial assessment of the problem severity and impact, in the
        case Seller first identifies the problem.

     o  Perform root cause failure analysis.

     o  Communicate corrective action to Buyer within a mutually agreeable time
        frame.

     o  Take whatever actions are deemed necessary, including additional

     o  Instruct Buyer in dispositioning Material if Material in Buyer's
        possession or at Buyer's customers' sites is affected or suspect.

     o  If required, discontinue shipment to Buyer until the corrective action
        has been proven to be satisfactory to Buyer.

     Buyer's personnel may become involved in problem evaluation activities at
     Seller's facility if Buyer determines that such involvement is necessary
     and appropriate, or if Seller requests such support. Any such involvement
     by Buyer however, shall not relieve Seller of its obligations hereunder.
     Seller's personnel may be requested to come to Buyer's facility to
     participate in problem evaluation activities to facilitate timely problem
     resolution.

     to time to address specific failures. Seller will be expected to respond to
     all such VCAR forms within [*] of receipt at Seller's facility.

     2.11 FAILURE ANALYSIS REPORTING

     From time to time, Material which does not meet Buyer's
     Purchasing/Engineering Specification shall be returned to Seller as set
     forth in the Agreement ("failed Material"). This section applies to all
     returned Material whether under warranty or not.

     When failed Material is detected at Buyer's facilities or at Buyer'
     customer site(s), it will be returned to Seller for analysis and repair.
     Seller shall generate a Failure Analysis Report listing returned Material
     by model and serial number, detailing type of failure, verification testing
     process performed, and whether or not the failure mode could be verified or
     duplicated. If the failure mode was duplicated, the report should also list
     specific action taken to repair the Material and any action(s) taken within
     Seller's manufacturing process or the design of the Material to prevent
     recurrence of the problem. Such Failure Analysis Report shall be provided
     to Buyer within [*] business days of receipt of failed Material at Seller's
     facility.

     Seller further agrees to perform upon request an expedited root cause
     analysis on selected failed Material. Such expedited Failure Analysis
     Report shall be provided within [*] business days as a goal.

     Unverified Material failures shall be prominently identified in the report
     to allow Buyer's personnel to engage in further analysis activities when
     the returned Material is received at Buyer's manufacturing facility. Should
     Buyer determine after further testing that such returned Material continues
     to demonstrate the same failure modes, Buyer shall return such Material to
     Seller for further analysis and corrective action.

       11.0   Measurement Precision

       Measurement Precision is the extent to which a repeated measurement gives
       the same result. Variations may arise from the inherent capabilities of
       the instrument, from variations of the operator's use of the instrument,
       or from changes in operating conditions. All instruments, gages and test
       equipment used to evaluate critical parameters shall be evaluated for
       Repeatability and Reproducibility as documented in the SDPR (Measurement
       System Analysis and Evaluation-Gauge R&R) and/or by means of similarly
       effective methods.

       12.0   Supplier Corrective Action Process Attachment C

       The supplier will use the [*] format attachment C and adhere to the
       required response times to report internal problem issues including
       failure to meet agreed upon quality goals. In the event that Compaq
       encounters problems affecting late product shipment, product shortage,
       and receiving inspection failures, in-line manufacturing failures,
       material purges, etc., Compaq will notify the Supplier and generate a
       Supplier Corrective Action Request (SCAR) using the [*] format.

                The Supplier is required to acknowledge receipt of the Request
       for Corrective Action within [*] supplier workday. The Supplier is
       required to define and implement an effective containment within [*]
       working days of receipt of the SCAR. A long term, corrective action plan
       should be available within [*] working days of root cause identification.
       The proposed timeframes should be considered general guidelines. Each
       SCAR should be assessed for its criticality and urgency and appropriate
       action taken. In the [*] the Supplier is expected to respond with the
       following information:

       ROOT CAUSE: [*]

       CONTAINMENT ACTION PLAN: [*]

       CORRECTIVE ACTION PLAN: [*]

       VERIFICATION PLAN: [*]


       13.0   Engineering / Process / Product Change Notification Guidelines

       Final approval is granted by Compaq, based on successful product analysis
       and qualification ([*] ) and is subject to audit by Compaq. The Supplier
       and all affected departments shall be notified in writing of the final
       status. Until formal, written approval is received, the Supplier is
       required to deliver standard product as required by Compaq Procurement
       and to maintain an adequate backup position in the event the change is
       rejected. Compaq will provide reasonable grounds for the rejection of any
       ECN. Exceptions to the above requirements will be made with issues that
       affect safety standards, data loss, failure to meet specifications,
       applicable laws, regulations or standards. Each ECN will be reviewed for
       criticality and urgency and appropriate action taken.

       14.0   Program Goals Attachment D

       services provided to Compaq.

       V.II   PRODUCTION QUALIFICATION AND VERIFICATION

       1.0    First Article Inspection

       The Supplier is required to submit first article samples. These samples
       shall be representative of final production and are required to meet all
       applicable specifications. The samples will be inspected/tested as
       required to verify conformance specifications. The First Article results
       will be documented and reviewed with the Supplier. Unacceptable results
       will require the Supplier to initiate and implement corrective action,
       after which another sample will be submitted for evaluation and final
       approval. It is the responsibility of the Supplier to procure and approve
       first article samples from its sub-tier suppliers. Compaq may, at its
       option, require the Supplier to submit such parts and/or review
       associated documentation.

       2.0    Capability Studies

Burn-in oven would require [*] time. All other commodities are [*] lead time for
[*] flex. Silkworm production capacity is currently [*] . Brocade reviews
capacity requirements on a [*] basis with our manufacturing partner and key
component suppliers. Capacity is assessed and documented for each step in the
manufacturing process, and capital requirements to support incremental increases
in capacity are documented and modified monthly.

Brocade has developed partnerships with suppliers of strategic components (e.g.,
ASICs, optical modules, Brocade unique components) that involve ongoing
communication of forecast information, technology roadmap exchanges, [*]
supplier performance reviews, executive forums, and supply chain optimization
activities. Brocade and [*] jointly manage Brocade's component supply base, with
Brocade as the lead for strategic components and [*] as the lead for standard
components. [*] provides turnkey inventory management.

Functional test (PCA)

At functional test the [*] is assembled into a [*] for test. The test is done
using the [*] test. This test executes on [*] ports. The ports [*] configured
such that certain [*]. The processor transmits [*] then enters a monitoring
state during which it prints status information to the telnet session.

       Burn-In

In burn-in an assembled switch runs the dynamic Burn-in test to cycle test for
[*] . Temperature is elevated to [*] for [*] and then to [*] for the remaining
burn-in time. The tests run include [*] Test, [*] test, [*] Test, [*] test, [*]
Test and [*] test. Automatic power cycling occurs [*] and monitoring is
performed.-

       Configuration

The switch is loaded with the port cards and GBICs according to customer
requirements. The manufacturing FW is replaces with customer specific FW.

       Final Test / Inspection

The configured switch is tested using a telnet session running the Special
System test that includes [*], [*], and [*] tests. A cosmetic inspection and a
final check of the configuration are done using appropriate customer checklist.

       Out Of Box Audit (OBA)

Units ready to be sealed are removed from their packaging and functionally
tested and inspected as called out in the appropriate instructions.


RELIABILITY TEST

From the packaging area [*] is loaded into the ORT test bed until a [*] units
are under test. A new unit is placed in test and the oldest unit is removed [*].
ORT consists of looping the [*] for [*]. The test environment remains at [*]
during this time. Brocade performed ORT from [*]. From [*] has been performing
ORT. Copies of the Brocade ORT procedure and the [*] instruction for ORT burn-in
log record is on file. [*] is currently performing the ORT testing. To date a
total of [*] switches accumulating [*] with [*] have been run. From [*] switches
were run and [*] were accumulated with [*] failures as follows:

                        COMPAQ SUPPLIER COMPLIANCE POLICY

Compaq Computer Corporation is proud of its reputation for integrity and honesty
in its business dealings. Our corporate culture of fairness and quality is one
of our most valuable assets. Maintaining this reputation is an ongoing process,

well as its suppliers. In fact, Compaq believes that it suppliers must operate
at the same high level of integrity as Compaq. In this regard, Compaq has
adopted a Supplier Compliance Policy. As part of this policy, Compaq suppliers
must comply fully with the requirements set forth below. This policy requires
that Compaq suppliers and their employees exercise the highest degree of honesty
and integrity in conducting their business with Compaq, as well as other third
parties.

        interest that create opportunities for abuses and allegations of
        commercial bribery.

        A.      Conflicts of Interest -- Suppliers are expected to avoid any
                action which may involve, or appears to involve, a conflict of
                interest with Compaq.

        B.      Business Courtesies -- Business should be won or lost on the
                merits of the products and services being offered by its
                suppliers. Therefore, supplier funds or personal funds of its
                employees should not be used to provide a business courtesy
                unless the gift is commemorative, ceremonial or customary in
                nature and has an insubstantial value. Under no circumstances
                should a kickback or bribe ever be offered to Compaq or its
                employees.

II.     ENVIRONMENTAL STANDARDS Compaq expects its suppliers to conduct their
        business in a manner that provides a safe, healthy and environmentally
        friendly workplace and meets or exceeds all applicable environment and
        work place legal requirements.

        A.      Hazardous Materials, Air Emissions & Waste Water Discharges --
                Compaq requires that each of its suppliers comply with all
                applicable environmental laws and regulations regarding
                hazardous materials, air emissions and waste water discharges,
                including those regarding the manufacture, transportation,
                storage, disposal, and release to the environment of such
                materials.

        B.      Health & Safety -- Compaq expects its suppliers to maintain
                their facilities in a safe and healthy manner and in compliance
                with all applicable laws and regulations.

III.    EMPLOYMENT STANDARDS Compaq expects its suppliers to foster human
        dignity by treating their employees fairly and with respect. Compaq
        requires that its suppliers comply with all applicable national, state
        and local employment laws.

        A.      Child Labor -- Compaq expect its suppliers to refrain from using
                child labor. Workers can be no less than 14 years of age and not
                younger than the compulsory age to be in school. Compaq supports
                the development of legitimate workplace apprenticeship programs
                for the educational benefit of young people.

        B.      Prison Labor -- Compaq expects its suppliers to refrain from
                utilizing prison or forced labor within their work forces.

        C.      Disciplinary Practices -- Compaq expects its suppliers to
                refrain from using corporal punishment or other forms of mental
                or physical coercion with their employees.

        D.      Working Hours -- Compaq expects its suppliers to comply with all
                applicable laws regarding compensation for overtime work
                performed by their employees. Additionally, employees should be
                allowed at least one day off in seven.

IV.     COMPETITIVE STANDARDS Compaq expects its suppliers to compete fairly and
        vigorously within the marketplace. Compaq discourages anti-competitive
        practices by its suppliers that inhibit the operation of a free-market
        economy. Compaq requires that its suppliers comply with all applicable
        competition laws.

        A.      Price fixing -- Compaq expects its suppliers to refrain from
                collaborating with competitors to fix prices for its goods.

        B.      Anti-competitive Practices -- Compaq will not tolerate
                anticompetitive practices by its suppliers, including efforts to
                allocate markets or customers among their competitors or to fix
                bids.

V.      CONFIDENTIALITY Compaq requires that its suppliers enforce a policy that
        ensures the confidentiality of all proprietary or confidential
        information provided by Compaq.

        A.      Non-disclosure Agreement -- Compaq requires that its suppliers
                comply with the terms of the Confidentiality and Non-disclosure
                Agreements that have been entered into with Compaq.

        B.      Other Confidentiality Obligations -- Compaq requires its
                suppliers to refrain from making unauthorized disclosures to
                Compaq of third party confidential information.

VI.     COMPLIANCE WITH GOVERNMENT LAWS AND REGULATIONS Compaq expects its
        suppliers to comply with all applicable laws and regulations governing
        their business relationships with Compaq. In addition, Compaq requires
        that its Suppliers agree to implement and maintain a Small, Woman-Owned,
        Minority Business Enterprise (SWMBE) program in accordance with Federal
        Acquisition Regulations (FAR) 52.219-0(d)(ll)(iii). Upon request by
        Compaq, Suppliers agree to provide Compaq with written certification of
        its compliance with the SWMBE Federal Acquisition Regulations.

Compaq is dedicated to maintaining its reputation for fairness and integrity. In
many ways the future success of both Compaq and its suppliers depends on our
ability to build on these high standards.

The foregoing requirements are not intended to be all-inclusive, and Compaq
expects its suppliers to exercise ethical judgment beyond strict compliance with
the law, and to be responsive to the concerns of the communities in which they
operate. Failure to comply with the above requirements may result in reduction
of business with Compaq, or in some instances, termination of your relationship
with Compaq. Understanding and complying with the above requirements will help
to ensure that our mutual business activities are conducted in the highest
ethical and professional manner.

                  DOCUMENTATION, TRAINING AND TECHNICAL SUPPORT

I.      SERVICE AND SUPPORT REQUIREMENTS

        Buyer will be responsible for working directly with the End Users, and
        Seller Support will work directly with Buyer to support Buyer personnel,
        as necessary. Buyer represents and warrants that it is experienced in,
        capable of, and staffed to provide, Level 1 and Level 2 support (as
        defined below). Seller offers training programs to assist in attaining
        this level of expertise on Seller Products. Seller Support will accept
        calls for technical assistance only from Level II engineers who have
        attended Seller instructed training Courses 1 through 3.

        Seller will provide Level 3 support (as defined below).

II.     SUPPORT LEVEL DEFINITIONS

           1.0 LEVEL 1 SUPPORT

        Level 1 support is the first line, direct End User contact, most likely
        via a telephone call handling group provided by Buyer. Level One support
        includes:

           -  First contact, direct Buyer/End User interaction

           -  Information collection and analysis

           -  Identification of whether the problem is known and has a known
              solution

           -  Troubleshooting and problem reproduction

           -  Problem report administration and tracking

        The parties agree that End Users shall not have the right to contact
        Seller directly for questions related to the Products.

           2.0 LEVEL 2 SUPPORT

        Level 2 support is "technical support" provided by Buyer personnel.
        Level 2 support is typically provided by experts in the applicable
        Product and who serve as the escalation point for Level 1. Level 2
        support personnel are expected to resolve all known problems,
        installation and configuration issues, assist in firmware or driver
        updates at the End User site, search Seller posted Technical Notes and
        other technical information supplied that will assist in providing
        problem resolutions. All pertinent data shall be entered in Buyer's
        problem tracking database.

        Should the Level 2 analyst be unable to resolve a problem, either
        because of lack of expertise, exhausted troubleshooting knowledge, or
        expiration of the allotted Level 2 resolution time, the Level 2 analyst
        may escalate the problem to Level 3 for resolution. Level 2 personnel of
        Buyer will continue to diligently work with Level 3 personnel of Seller
        to accomplish resolution. Level 2 personnel of Buyer will communicate
        all resolutions back to the End Users.


                                       81
<PAGE>   82
Escalations should be presented to Seller engineers in the form of a problem
tracking data base record with all pertinent configuration detail and failure
information or symptoms documented in detail.

In an effort to maintain an efficient support organization and crisp exchange of
information, Buyer will limit the number of support personnel (Level 2)
authorized to contact Seller (Level 3) to [*] and ensure that these personnel
have attended courses 1, 2, and 3 taught at the Seller training facility.

          3.0 LEVEL 3 SUPPORT

Level 3 support is provided by Seller System Engineers (SE) and/or Technical
Support Engineers (TSE). Level 3 is the first point of contact for technical
issues between Seller and Buyer. Once a problem is accepted by Seller in its
sole discretion for escalation to Level 3, Seller is responsible for resolution
and will utilize commercially reasonable resources to resolve such problem.

Prior to escalating to Level 3, it is expected that Buyer shall provide the
following information and documentation:

           -  Any error information from the device connected to the switch and
              from the switch.

           -  All names and revisions of hardware equipment.

           -  All firmware revisions of the drivers.

           -  Any log files from the devices connected to the switch.

           -  Any trace file from the devices connected to the switch.

           -  The configuration information of the equipment being used.

           -  Detailed definition of all steps taken to reproduce and resolve
              this situation prior to escalation to Level 3.

Assigned Level 3 support personnel (SE and/or TSE) can be contacted via direct
dial, email to an established "support" alias, web site initiated input, and by
calling Seller's [*] support number. Direct access to Seller support personnel
will be possible during normal Seller's business hours (8 AM to 5 PM PST, M-F).
Emergency situations for [*] problems are handled via [*] at [*].

          4.0 SELLER'S SEVERITY

Definitions and Support Goals

The goal for initial response time to all telephone support requests is [*] or
less during normal Seller working hours. For after hours telephone requests, the
goal is [*] or less. The targeted response time for requests submitted by other
means, such as email, or fax, is [*].
