   "Rescheduling and Cancellation":

   "Except for Products identified in Section 4.0 "Replenishment Logistics
   Attachment", Products will be subject to the terms herein stated in Section
   3.0."

4. Section 4.0, "Replenishment Logistics Attachment" delete in its entirety and
   replace with the following:

   "4.0 REPLENISHMENT LOGISTICS ATTACHMENT

   4.1 PULL DEFINITIONS
   "Pull Products" means Products specified in the Pull Product Profile in
   Section 4.6 below. "Pull Product Profile" or "Pull Profile" or "MIRS Profile"
   means the table in Section 4.6 below, describing the Pull Products and
   process including, but not limited to, Product Type, Part Number,
   Replenishment Lead-Time and Packaging Specifications.

   "Pull Purchase Order" or "Pro forma Purchase Order" or "PPO" means a blanket
   PO used for invoicing, receiving and forecasting purposes and does not
   represent a firm offer by Buyer nor bind Buyer to any quantity or delivery
   date.

   "Upside Flexibility" means a percentage of Pull Products specified in the
   Pull Profile in excess of the Planning Schedule Quantity.

   "Buffer Inventory Replenishment Lead-time" means the time from Seller's
   receipt of Buyer's Planning Schedule for Supplier to replenish the Buffer
   Inventory.

   "Planning Schedule" means Buyer's forecast of requirements for Pull Products.

   "Pull Notification" or "Shipping Schedule" means Buyer's only authorization
   (WA) for Supplier to deliver a specified quantity of Pull Products.

   "Pull Notification Lead-Time" means the time from Supplier's receipt of a
   Pull Notification to shipment of the Pull Products to Buyer's location.

   "Pull Program Inventory" means the minimum inventory for which Supplier is
   responsible to maintain, to satisfy Buyer's quantities as specified in the
   Planning Schedule.

   "Buffer Inventory" means the additional inventory that Supplier keeps as a
   safety inventory.

   4.2 PLANNING
   Buyer will issue a PPO to Supplier for all Pull Products. Buyer may issue a
   Planning Schedule at intervals as specified in the Pull Profile, the most
   recent Planning Schedule to supersede all previous Planning Schedules. The
   Planning Schedule provides a forecast of requirements for the Pull Products
   and establishes Upside Flexibility, if any, with the Supplier.

   4.3 PULL DELIVERY
   Supplier will deliver to Buyer on the delivery date the Pull Products
   specified in the Pull Notifications issued by Buyer, provided such Pull
   Notifications do not exceed the Planning Schedule Quantity. To the extent
   practicable, Supplier will comply with Pull Notifications for quantities of
   Pull Products in excess of the Planning Schedule Quantity, but at a minimum
   in accordance with the Upside Flexibility.

   4.4 PULL LIMITATION OF LIABILITY
   Buyer makes no representation or warranty and assumes no liability regarding
   the quantity of Pull Products that it will purchase.

   4.5 END OF LIFE ORDER
   Pull Products that Supplier has provided a written End of Life notice to
   Buyer will not be subject to the terms contained in Section 4.0 Replenishment
   Logistics Attachment, effective when Buyer submits a EOL purchase order (WA)
   for such products pursuant with Section 2.10 "Notice of Product Withdrawal"
   of SOW#1.

                unit quantity; (ii) unit price; (iii) shipping destination; (iv)
                Shipment Date; and (v) other instructions or requirements
                pertinent to the Order. HP may schedule regular intervals for
                deliveries by an appropriate Order setting forth the intervals.
                To the extent of any inconsistency between the terms of an Order
                and the terms of this Agreement, the terms specified in this

                contained in Orders or Supplier's Order acknowledgements shall
                not be binding unless accepted by the other party in writing.

        3.2     Order Acknowledgment. An Order will be deemed to have been
                placed as of the date of receipt of the Order by Supplier.
                Supplier will promptly confirm the receipt of an Order

                exceeding Forecast, Supplier will have [*] in which to reject
                the order with respect to the excess. If an HP Order exceeds the
                Forecast or shortens the Lead Time, Supplier will use
                commercially reasonable efforts to fill such excess or
                accommodate such shorter Lead Time.

        3.3     Emergency Orders. If HP deems it necessary, HP may order OEM
                Products by facsimile on an emergency basis ("Emergency Order")
                subject to the availability of such OEM Products in Supplier's
                inventory. Supplier will use all reasonable efforts to ship the
                Emergency Order to HP's designated Eligible Purchaser(s)
                immediately upon receipt of such Emergency Order by Supplier.
                Subject to HP's approval, HP will pay any additional expenses
                related to such Emergency Orders.

        3.4     Forecasts. HP will provide a [*] rolling Forecast [*] of its
                projected Orders. Any quantities listed in any Forecast or other
                correspondence between the parties are only estimates made as an
                accommodation for planning purposes and do not constitute a
                commitment on HP's part to purchase such quantity. HP may, [*]
                revise any such Forecasts, provided that such revisions (i)
                occur at least [*] prior to the projected Order Shipment Date,
                and (ii) shall not result in an increase of its projected Orders
                greater than [*] of the amount of Orders in the immediately
                preceding Forecast. Quantities and Shipment Dates in Forecasts
                and revisions thereof which are not provided to Supplier in
                accordance with this Section 3.4 shall not be binding upon
                Supplier for the purposes of Section 3.2 above.

        3.5     Lead Time. Lead time for each OEM Product and FRU product will
                be no more than [*] for forecasted demand and [*] unforecasted
                demand [*].

        3.6     Inventory Requirement. Supplier will maintain a [*] equal to [*]
                to support Order changes for each OEM Product. If this inventory
                is [*], Supplier will [*] as soon as reasonably possible after

        3.7     Order Changes. HP may [*], postpone, decrease, or reschedule any
                Order subject to the [*] set forth immediately below. In the
                event HP increases any Order, Supplier will use [*] reasonable
                [*] to fulfill such Order for the Shipment Date requested by HP.

                subject to Supplier's concurrence (which such concurrence shall
                not be unreasonably withheld or delayed) creates a significant
                risk to the health or safety of individuals who operate the OEM
                product or to the continuous business operations of companies or
                organizations that employ the OEM product for an intended or
                reasonably foreseeable use.

                Supplier warrants that all Support will be provided in a
                professional and workmanlike manner. HP will provide direct
                maintenance and support to HP's customers with respect to the
                use of the OEM product as distributed with HP Products. Supplier
                and HP will maintain and support each OEM product distributed by
                HP for at least [*] after the date of last shipment by Supplier
                to HP of that OEM Product or end-of-life, whichever occurs
                first. HP acknowledges that Supplier may independently offer and
                provide support services to OEM Product customers. However, in
                no event may Supplier use HP Confidential Information or HP
                Property to direct or provide such support without HP's prior
                consent. Response times and problem classification for the OEM
                Products will be as set forth in Exhibit (D).

        10.2    New HP Products. Upon request by HP, Supplier will use its
                commercially reasonable efforts to provide HP with the OEM
                Products adapted for use with new releases of HP Products [*]
                and [*], if any, to be negotiated by the parties, provided that
                HP makes available to Supplier such HP Property as may be
                reasonably necessary for Supplier to develop any adaptation.

        10.3    HP Property. HP may provide to Supplier HP Property under the
                terms of an HP Equipment Loan Agreement attached as Exhibit E to
                this Agreement, solely for use in Supplier's manufacturing,
                testing, adapting and supporting the OEM Products. All HP
                Property will be clearly segregated from Supplier's property and
                identified as the sole property of HP. HP Property may not be
                transferred, assigned, loaned or otherwise encumbered in any
                way. HP Property may be provided to third parties for
                fulfillment of Supplier's obligations hereunder only upon HP's
                prior written consent. HP property will be returned to HP [*],
                upon termination of this Agreement.

        10.4    Substitute Products. If Supplier develops any generally
                available products that are to replace the OEM Product(s) or
                that are the same or substantially similar to the OEM Products
                available under this Agreement, HP will have the right to
                substitute the newer products at [*] as the substantially
                similar OEM Products for all subsequent purchases under this
                Agreement. Such substitute products must be compatible with the
                current version of the OEM Products.

        10.5    Failure Rate. Notwithstanding that the warranties given in
                Section 9.1 above apply to [*] of the hardware components of OEM
                Products, Supplier and HP acknowledge that a failure rate of [*]
                per [*] units delivered over a [*] is expected. If the actual
                failure rate for OEM Products exceeds this expected rate,
                Supplier will provide additional engineering and technical
                support needed to bring the actual failure rate within the
                specified failure rate.

        10.6    Class Failure Remedies. Upon the occurrence of any of the
                following events: (i) a failure rate exceeding the rate
                specified in Section 10.5 above; (ii) an epidemic failure as
                described in Section 9.3; or (iii) a safety standard change
                under Section 7.5 above (each referred to as a "Class Failure"),
                HP will have the following additional remedies for a [*] period
                commencing upon shipment by Supplier to HP of the OEM Product or
                the corresponding HP Product:

                             BROCADE/HP CONFIDENTIAL

               (1)    In the event of a Class Failure, Supplier will use its
                      commercially reasonable efforts to provide an initial root
                      cause analysis, failure analysis, and [*] plan to HP no
                      later than [*] following the receipt of the Class Failure
                      part. HP will make available such information and
                      assistance as reasonably required to allow Supplier to
                      conduct its root cause analysis and provide its corrective
                      action plan.

               (2)    If, after review of the root cause analysis and [*] plan,
                      HP determines in its reasonable opinion that the Class
                      Failure necessitates a field stocking recall or customer
                      based recall or retrofit, then HP will notify Supplier of
                      its determination for such remedy. Supplier shall have [*]
                      from time of notice from HP to object to HP's
                      determination. In the event that Supplier either agrees
                      with or fails to notify HP of its objection, HP may then
                      elect to have the OEM products: (i) returned to Supplier
                      for repair or replacement; (ii) repaired or replaced by
                      Supplier in the field; or (iii) repaired or replaced by HP
                      in the field, including products in distributor inventory
                      and HP's installed base. If HP chooses to perform a field
                      repair, Supplier will provide the appropriate replacement
                      OEM products, spares, or upgrades [*] to HP and will,
                      within [*] after completion of the recalls or retrofits,
                      reimburse HP for [*] in performing such field repair.
                      Supplier will give such OEM products, spares, or upgrades
                      the [*].

               (3)    Except as provided in Section 7.5 above regarding safety
                      standard changes, Supplier will, within [*] after
                      completion of the recalls or retrofits, reimburse HP [*]
                      in performing such services.

        10.7    Survival Of Support Obligations. Supplier's maintenance and
                support obligations specified in this Article 10, and in the
                Support Terms in Exhibit D will run for the Term and any
                additional periods under Section 1.3 above and will continue for
                a period of [*] after the date of Supplier's last shipment of
                the applicable OEM Product to HP, or [*], whichever occurs
                first. This obligation includes, without limitation, making
                necessary Parts available to HP as further provided in the
                Support Terms.

11.     OBSOLESCENCE AND MANUFACTURING RIGHTS

        11.1    Lifetime Buy Rights. Supplier acknowledges its obligation to
                manufacture, supply and support the OEM Products without
                interruption for the Term. If, however, after the [*] of
                shipment of such products, Supplier seeks to discontinue the
                supply or support of any OEM Product (a " Discontinued
                Product"), Supplier will give notice to HP no less than [*] in
                advance of the last date the Discontinued Product can be
                ordered. After receipt of notice of discontinuance, HP may place
                orders for any demand during the [*] of such notice for delivery
                of Discontinued Products prior to the end of the notice period.
                To the extent that such orders exceed HP's previous Forecast for
                such Discontinued Products, the orders shall be [*]. Supplier
                shall accept only forecasted orders in the [*]

                agreed upon [*] for the Term of the Agreement and Supplier's
                support obligations. HP may further request and Supplier will

                training [*] as reasonably necessary to inform HP personnel of
                upgraded, enhanced or new versions of the OEM Products. Other
                training will be provided upon mutually agreeable terms and
                conditions.

        12.2    Presales Training. Supplier will provide to HP presales training

                [*]. Without limiting the generality of the foregoing sentence,
                nothing in this Agreement will be construed or interpreted to
                place a [*] obligation upon HP with respect to marketing or
                distributing the HP Products or OEM Products or preclude HP from
                [*] any product which performs the same or similar function as
                the OEM Products. HP will have the right to use its own business
                and license terms for all marketing and distribution of the OEM
                Products and HP Products.

        13.2    Distribution Rights. For [*] from the Effective Date, Supplier

                private label versions of the OEM Products, it is the intent of
                the parties that the terms and conditions of this Agreement will
                govern such private label version of the OEM Product.
                Notwithstanding the above, the parties recognize the necessity
                of renegotiating and amending the following sections of the
                Agreement: Article 3, Article 4, Article 7, Section 10.5,
                Exhibit A, Exhibit C, Exhibit D(6), and Exhibit H. The parties
                agree that such renegotiation of the preceding sections shall be
                in good faith and shall not be unreasonably delayed.

19.     CONFIDENTIAL INFORMATION

        19.1    Confidential Information. During the Term, a party (the
                "Recipient") may receive or have access to certain information
                of the other party (the "Discloser") that is marked as
                "Confidential Information," including, though not limited to,
                information or data concerning the Discloser's products or
                product plans, business operations, strategies, customers and
                related business information. The Recipient will protect the
                confidentiality of Confidential Information with the same degree
                of care as the Recipient uses for its own similar information,
                but no less than a reasonable degree of care, under the terms of
                the Confidential Disclosure Agreement attached as Exhibit F (the
                "CDA"). To the extent any term of this Agreement conflicts with
                any term in the CDA, the terms of this Agreement will control
                and take precedence. Confidential Information may only be used
                by those employees of the Recipient who have a need to know such
                information for the purposes related to this Agreement. The
                parties acknowledge that all Technical Information and Forecasts
                are deemed Confidential Information to be protected for a term
                of [*] from the date of disclosure.

        19.2    Exclusions. The foregoing confidentiality obligations will not
                apply to any information that is (a) already known by the

                party with no duty of confidentiality, (e) disclosed by the
                Recipient with the Discloser's prior written approval, or (f)
                disclosed under operation of law. In the event that a party
                becomes aware that disclosure is likely to be required by
                operation of law, the party having knowledge of such possible
                disclosure will provide the other with ample notice and
                opportunity to seek a protective order.

20.     INSURANCE REQUIREMENTS

                Such insurance policies will be written with appropriately

                years after termination of this Agreement. Any such coverage
                must have a retroactive date no later than the date upon which
                work commenced under this Agreement.

        20.3    Additional Requirements. All deductibles on policies providing
                coverage will be paid by Supplier. In the event Supplier is self
                insured for matters described in Section 20.1, Supplier agrees
                to respond to any claims or losses made against or incurred [*]
                had been purchased with the [*] than what is generally available
                to similar suppliers. In no event will the coverages or limits
                of any insurance required under this Article, or the lack or
                unavailability of any other insurance, be deemed to [*]
                Supplier's [*] to HP under this Agreement.

                prepaid, properly addressed to the receiving party. Notices may
                also be delivered by telefax and will be validly given upon oral
                or written confirmation of receipt. Either party may change its
                address for purposes of notice by giving notice to the other
                party in accordance with these provisions.

        23.2    Exhibits. Each Exhibit attached to this Agreement is deemed a
                part of this Agreement and incorporated herein wherever
                reference to it is made.

        23.3    Independent Contractors. The relationship of the parties
                established under this Agreement is that of independent
                contractors and neither party is a partner, employee, agent or
                joint-venturer of or with the other. Nothing in this Agreement
                precludes either party from independently developing,
                manufacturing, selling or supporting products similar to the OEM
                Products.

        23.4    Assignment. Neither party may, directly or indirectly, in whole
                or in part, either by operation of law or otherwise, assign or
                transfer this Agreement or delegate any of its obligations under
                this Agreement without the other party's written consent. Any
                attempted assignment, transfer, or delegation without such prior
                written consent will be void. Notwithstanding the foregoing, HP
                or its permitted successive assignees or transferees may assign
                or transfer this Agreement or delegate any rights or obligations
                hereunder without consent: (1) to any entity controlled by, or
                under common control with, HP, or its permitted successive
                assignees or transferees; or (2) in connection with a merger,
                reorganization, transfer, sale of assets or product lines, or
                change of control or ownership of HP, or its permitted
                successive assignees or transferees. Without limiting the
                foregoing, this agreement will be binding upon and inure to the
                benefit of the parties and their permitted successors and
                assigns.

        23.5    No Waiver. The waiver of any term, condition, or provision of
                this Agreement must be in writing and signed by an authorized
                representative of the waiving party. Any such waiver will not be
                construed as a waiver of any other term, condition, or provision
                except as provided in writing, nor as a waiver of any subsequent
                breach of the same term, condition, or provision.

        23.6    Reference To Days. All references in this Agreement to "days"
                will, unless otherwise specified herein, mean calendar days.

        23.7    Headings. The Section headings used in this Agreement are for
                convenience of reference only. They will not limit or extend the
                meaning of any provision of this Agreement, and will not be
                relevant in interpreting any provision of this Agreement.

        23.8    Publicity. Subject to the terms and conditions of Article 19
                above, neither party may publicize or disclose to any third
                party, without the written consent of the other party, the terms
                of this Agreement. Without limiting the generality of the
                foregoing sentence, no press releases may be made without the
                mutual written consent of each party.

        23.9    Severability. If any provision in this Agreement is held invalid
                or unenforceable by a body of competent jurisdiction, such
                provision will be construed, limited or, if necessary, severed
                to the extent necessary to eliminate such invalidity or
                unenforceability. The parties agree to negotiate in good faith a
                valid, enforceable substitute provision that most nearly effects
                the parties' original intent in entering into this Agreement or
                to provide an equitable adjustment in the event no such
                provision can be added. The other provisions of this Agreement
                will remain in full force and effect.

        23.10   Subcontractors and Subsidiaries. Each party unconditionally
                guarantees to the other party the performance of all obligations
                by any of its Subcontractors and Subsidiaries under the
                Agreement (including, without limitation, payment obligations),
                as amended from time to time, or any other obligation of any
                Subcontractors or Subsidiary to the other party, now existing or
                hereafter arising. If either party's Subcontractors or
                Subsidiary does not perform such obligation, such party shall
                immediately perform such obligation.

        23.11   Entire Agreement. This Agreement comprises the entire
                understanding between the parties with respect to its subject
                matters and supersedes any previous or contemporaneous
                communications, representations, or agreements, whether oral or
                written. For purposes of construction, this Agreement will be
                deemed to have been drafted by both parties. No modification of
                this Agreement will be binding on either party unless in writing
                and signed by an authorized representative of each party.

        23.12   Governing Law. This Agreement shall be governed and interpreted
                according to the laws of the State of California, exclusive of
                its choice-of-law provisions, and the parties hereby personally
                consent to the exclusive jurisdiction of the courts of the State
                of California or the United States District Court for the
                District of Northern California.

                                                   FIBRE CHANNEL FABRIC SWITCHES

[GRAPHIC IMAGE APPEARS HERE]

BROCADE fabric switches create the core infrastructure for constructing a
Storage or Server Area Network (SAN). The switches provide full fabric support,
true line-speed switching, and modular components to build a wide range of SAN
solutions.

The SilkWorm 2400 and SilkWorm 2800 create an intelligent connectivity
infrastructure, or Fabric, to support connectivity of a wide range of host and
storage types. Users share these resources efficiently in a SAN. Fabric services
are deployed automatically and transparently throughout the Fabric to assure it
is resilient to failures. The Fabric is scalable, expanding rapidly to
increasing demands by users for highly available, heterogeneous access to
growing storage pools.

SilkWorm switches provide the cornerstone for a wide range of SAN
configurations--from NT-based workgroups to large enterprise solutions. Fabric
switches have the capability to cascade, further increasing a Fabric's
scalability and resiliency. A multiple-switch Fabric can connect thousands of
Fibre Channel ports. SilkWorm switches meet the needs of a broad range of SAN
applications, including storage consolidation, enterprise backup, and clustering
environments.

Best-of-class products conforming to industry standards

-       Each port (B for the SilkWorm 2400 and 16 for the SilkWorm 2800)
        delivers 100 megabytes-per-second (MB/sec) line-speed. Universal ports
        automatically determine the port type for a loop, point-to-point
        devices, or an Inter-Switch Link (ISL).

-       Non-blocking architecture guarantees full-speed data delivery
        irrespective of traffic conditions. Cut-through routing guarantees
        maximum latency of 2 microseconds across a switch.

-       Buffer-pool management and use of mini-buffers for small frames optimize
        overall performance.

-       GBIC (Gigabit Interface Converter) -based modular design makes it easy
        to hot-swap connections quickly. Copper and short-or long-wave-length
        fiber cabling may be mixed on the same switch in any combination.

-       Self-learning allows the Fabric to automatically discover and register
        host and storage devices.

        BROCADE's translative mode automatically registers private-loop devices
        for Fabric-wide access.

        [GRAPHIC IMAGE APPEARS HERE]

-       Self-healing enables the Fabric to isolate a problem port and reroute
        traffic onto alternate paths.

-       Optional hardware-enforced Zoning secures data access among switch
        ports.

MAXIMUM SCALABILITY TO PROTECT INVESTMENTS

-       Multiple simultaneous conversations are supported, achieving higher
        bandwidth than possible on a hub-based Fibre Channel loop.

-       A SAN expands seamlessly to include thousands of ports by adding new
        switches to the Fabric. ISLs are automatically detected. Fabric
        information is updated to newly updated switches.

FABRIC OS(TM) TO SAFEGUARD MISSION-CRITICAL BUSINESS

-       Simple Name Server registers information about the host and storage
        devices in the SAN. Registered State Change Notification (RSCN) informs
        the SAN when a device state changes.

-       Alias Server supports the Multicast Service, which broadcasts data to
        all members of a group.

-       BROCADE ZONING (optional) limits access to data by selected ports or
        devices.

-       Services are distributed and managed across the entire Fabric, ensuring
        simple management with no single point of failure.

-       Routing software automatically configures the network, detects link
        failure, and reconfigures without operator interaction.

-       Software is upgradable for additional features and enhancements by
        downloading the latest version of Fabric OS.

INDUSTRY-LEADING RELIABILITY AND SERVICEABILITY

-       Front control panel on the SilkWorm 2800 simplifies administration.

-       Power-On Self Test (POST) and online diagnostics allow monitoring and
        thorough port-level testing while the switch is running Extensive
        offline diagnostics assist in rapidly isolating a Field Replacable Unit
        (FRU).

-       Embedded port-monitoring facilities automatically disable failing ports
        and restart them when the problem has cleared.

-       Redundant cooling fans and an optional, redundant, hot swappable power
        supply increase switch availability.

-       Low parts count increases switch reliability.

                             BROCADE/HP CONFIDENTIAL

SIMPLE MANAGEABILITY

-       Support for industry-standard MIBs (Management Information Blocks) gives
        standardized SNMP (Simple Network Management Protocol) access to switch
        information

-       Broad set of interfaces (Telnet, SNMP, Web, or SES) provide flexible
        integration into the enterprise management infrastructure.

ADVANCED SAN CONFIGURATION CONTROL AND MANAGEMENT (OPTIONAL)

-       BROCADE WEB TOOLS for online SAN management and switch administration.

-       BROCADE SES (SCSI-3 Enclosure Services) for management without
        implementing IP.

-       BROCADE ZONING for finer segmentation of the Fabric to increase security
        and configuration possibilities.

-       QuickLoop(TM) for configuration of one or more logical loops in the
        Fabric, and enhanced connectivity and management of private devices.

4.      LABELING

        4.1.   GENERAL

               4.1.1. LABEL MATERIAL AND TESTS

               The label material and adhesive shall be suitable for use on the
               material it is to be applied (e.g. plastic or metal...). Also,
               the label must be "permanent" in that it will be destroyed or
               made unserviceable if removed (UL and CSA approved label systems
               meet this criteria).

               -      CSA label identification logo on each label or bulk
                      labeled if there is no printing on the label

               -      UL Recognized label system (bulk marking for labels)

               Rub label for 15 seconds with water and another 15 seconds with
               kerosene (or other petroleum spirits). All markings shall be
               legible. It shall not be easy to remove the label from the
               applied surface without damage to the label and the information
               shall be legible.

               4.1.2. LOCATION

               The label must be in an area visible to the operator. This is the
               front, sides or rear of the unit and on the bottom if the product
               is light. The label must also be on a permanent part (attached by
               screws is OK) of the unit and not on a part that is likely to be
               discarded.

               4.1.3. REGULATORY MARKINGS

               Proof of certification by any agency is the approval agencies
               symbol and number, typically on the product. Unless otherwise
               noted, the information must be legible with no minimum size. Also
               included are other markings required for agency approval.

               Engineer. Traceability is mandatory with this serial number.
               BROCADE serial number will appear in two places
               -BROCADE regulatory label (see section 4.2.1 for label placement)
               -HP product label (see section 4.2.1 for label placement)

               4.3.2. OTHER SERIAL NUMBERS

               Brocade shall ensure that any other serial numbers applied to
               components are unique and are traceable to the top level assembly
               (A5624-62001) serial number.

        4.4.   BAR CODE REQUIREMENTS:

        a.     The bar code symbol bar shall be Code 39 (also known as "Code 3

                             MAINTENANCE AND SUPPORT

1.      GENERAL TERMS

        1.1.    Scope. Supplier will provide maintenance and support services to
                HP as specified in these Support Terms to allow HP to provide
                effective service to end-user customers of the Programs
                ("Customers"). Unless otherwise agreed, HP will serve as the
                primary support contact with Customers, and Supplier shall have
                no direct end-user customer support obligations except as
                otherwise provided herein. The obligations of each party are
                specified below.

        1.2.    Definitions. The following capitalized terms will have these
                meanings when used in these Support Terms:

                1.2.1.  "Action Plan" means the initial plan to be created and
                        implemented by Supplier in response to an HP Problem
                        Resolution or Escalation request. At a minimum, the
                        Action Plan must contain the following:

                        [*]

                1.2.2.  "Escalation" is the process described in Article 4 below
                        through which HP declares that a Customer situation
                        requires immediate action. Under this process, the
                        nature and severity of the problem is raised in each
                        party's organization and additional resources are
                        allocated as specified in these Support Terms toward
                        solving the problem.

                1.2.3.  "Fix" means a change in a Program that removes a problem
                        in that product. A Fix must be designed and tested so
                        that it can be distributed to all Customers. A Fix may
                        be temporary or permanent. A temporary Fix may be a
                        patch or bug fix that temporarily modifies a Program or
                        any software in the product without rebuilding that
                        product. A permanent Fix provides a permanent solution
                        to the problem, agreed upon by both HP and the Supplier.

                1.2.4.  "Problem Resolution" is the process described in Article
                        3 below through which HP submits a Request for Technical
                        Assistance to notify Supplier when a problem (such as a
                        fault or defect) is suspected in a Product. Under this

<PAGE>

                        process, HP confirms the problem diagnosis with
                        Supplier, and the parties cooperate to resolve the
                        problem.

                1.2.5.  "Support Information" means Program Service Information
                        and a Knowledge Data Base of known problems related to
                        Supplier's support of Programs.

                1.2.6.  "Status Update" means Supplier's summary of the problem,
                        describing the possible cause and the incremental work
                        to be performed to reach resolution, including the
                        Action Plan and the availability date of a Fix.

                1.2.7.  "Technical Assistance" is the process described in
                        Article 2 below through which HP obtains assistance from
                        Supplier in the support of Customers. Technical
                        Assistance includes the exchange of information, such as
                        product configuration, product operation, or other
                        necessary answers or assistance to support questions.

                1.2.8.  "Tracking System" means an electronic database to be
                        maintained by the parties for updating and communicating
                        information pertaining to Service Requests, Technical
                        Assistance, Problem Resolution and Escalation. The
                        particular type of Tracking System will be mutually
                        determined, as more particularly described in Section
                        1.7 below.

                1.2.9.  "Workaround" means a temporary solution or temporary Fix
                        that restores operational capability for the Product,
                        without severely compromising the performance of that
                        product, until a permanent Fix is available. A
                        Workaround can be a change in the configuration or a
                        change in Customer documentation.

        1.3.    General Obligations. Each party agrees to the following general
                terms:

                1.3.1.  For each Program, Supplier will provide a product

        Equipment Schedule signed by SUPPLIER and appended to this Equipment
        Loan Agreement. SUPPLIER agrees, by its receipt of HP Equipment, that

        items of HP Equipment.

3.      USE. SUPPLIER may use the HP Equipment solely for testing and developing

        Equipment is non-transferable. SUPPLIER assumes all risk for the use of
        the HP Equipment.

4.      SOFTWARE. All software provided with the HP Equipment or for test and
        development of the OEM Products shall be licensed under the then current

        statements (and any appropriate amendments thereto) under the provisions

        the HP Equipment in any manner.

6.      WARRANTY DISCLAIMER. ALL HP EQUIPMENT IS FURNISHED "AS IS", WITHOUT
        WARRANTY OF ANY KIND, WRITTEN OR ORAL, EXPRESS OR IMPLIED, INCLUDING BUT

        access to the HP Equipment for such maintenance and support.

        HP. All HP Equipment returned to HP must include the same components as
        received by SUPPLIER, and must be in good operating order and condition.
        Charges may be imposed by HP if SUPPLIER fails to return the HP

        SUPPLIER shall (i) return to HP all HP Equipment [*] or (ii) purchase
        the HP Equipment pursuant to Section 12 below. In the event that
        SUPPLIER fails to return the HP Equipment to HP upon expiration of the
        Term within such [*] SUPPLIER shall be deemed to have elected to
        purchase the HP Equipment, and HP will invoice SUPPLER accordingly.

12.     PURCHASE OPTION. Upon expiration of the Term, SUPPLIER may elect to
        purchase the HP Equipment from HP under HP's then current standard terms
        and conditions, provided that such HP Equipment shall not be purchased
        for resale. Upon purchase, such HP Equipment will be provided with HP's
        then current standard warranty provisions for used equipment. The
        purchase price for HP Equipment purchased under this Section 12 will be
        the [*] less any mutually agreed discount. No other promotional or
        purchase discounts will apply. Such purchase will not qualify for any

1.  PURPOSE

               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 [*]. The Product
               must consistently [*] 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 mutually a-reed upon failed
               units, and provide the data of failure symptoms observed or NTF
               (No Trouble Found), on all units returned from HP worldwide
               manufacturing sites.

               [*]

        2.2 DOCK-TO-STOCK

        In general, material is received directly to stock, unless a [*] is
        required (see Section 2.3, HP [*] & Section 3 In-Process Quality Audit
        at BROCADE). All new products must go through a [*] HP-ESBU. In
        addition, all new suppliers must demonstrate relevant process control
        through a quality system [*] Provided both conditions are successfully
        fulfilled, the subsequent shipments will not be inspected as they are
        received by HP-ESBU.

[*] HP Incoming [*]

HP shall [*] the [*] units received from the Supplier. If there
are four functional failures, ten cosmetic failures, or a combination of both
totaling ten, HP shall [*]. A manufacturing team consisting of at least the
materials and product engineers shall perform the [*].

All failures require a [*] report completed by the Supplier [*] days after
notification. If the Supplier needs the [*] unit to determine the root cause,
the Supplier shall complete a [*] report within [*] after receipt of the [*] The
report shall contain detailed explanation of the root cause and [*](s)
performed. HP shall [*] the report during the [*].

3.  OOBA LOT SAMPLE INSPECTION AT BROCADE

        3.1    OOBA LOT SAMPLE INSPECTION

        OOBA is performed after a [*] on the Brocade manufacturing line. If
        there is going to be an error on the line it will be gross error that
        would be seen in all the units. This is what OOBA is designed to catch.
        The focus of OOBA, therefore, is to screen for gross failures, rectify
        and, lots with problems, and implement [*] based on the observed
        failures.

        The In-Process Lot Sample Inspection has been established at the levels
        specified in the following chart for each part number. The In-Process
        Lot Sample Inspection shall be used when determining the Q1 score for
        the TQRDC/E review.
