of the parties set forth herein, the parties hereto agree as follows:

1. THE FOLLOWING DEFINITIONS ARE HEREBY ADDED TO SECTION 1, DEFINITIONS, OF THE
AGREEMENT.

1.15 "DAYS" means calendar days unless otherwise noted.

THE FOLLOWING SECTION 7.0A, FORECASTS, PURCHASE ORDERS TERMS AND CONDITIONS
AND DELIVERY FOR PRODUCTS LISTED IN EXHIBIT A, FIGURES A-2 AND A-3 IS HEREBY
ADDED TO THE AGREEMENT.

7.0A    FORECASTS, PURCHASE ORDERS, TERMS AND CONDITIONS AND DELIVERY

<Page>

7.1A FORECASTS. EMC agrees to use [*] to provide McDATA with good faith
monthly rolling forecasts for [*] of EMC's estimated Product(s) and Spare(s)
purchase requirements. EMC's forecasts are for planning purposes only. EMC is
under no obligation to purchase forecasted quantities and if EMC fails to
purchase any forecasted quantities, EMC shall have no liability of any kind
(except as detailed in this Amendment ) nor incur any penalties or
retroactive price increases unless otherwise agreed to by EMC in writing.
Accordingly, any commitments to buy are only valid upon EMC's issuance of
purchase orders as defined in Section 7.2A below and as detailed in this
Agreement. McDATA shall use [*] to establish a supply line that results in
sufficient material being available at the beginning of each month to support
EMC's monthly forecast and McDATA shall use the efforts set forth in Section
7.3.2A to support the upside supply requirements detailed in Section 7.3.2A
of this Agreement. McDATA shall respond in writing within [*] of receipt of
EMC's forecast if it cannot support the requested quantities.

7.2A PURCHASE ORDERS. EMC shall submit a binding, written purchase order for
all Product(s) and Spare(s) ordered from McDATA. EMC may transmit purchase
orders by facsimile. Purchase orders shall specify EMC's part numbers,
Product(s) and/or Spare(s) model numbers, quantity ordered, shipping
destination, carrier, and delivery dates, which dates shall be no more than
[*] from the date of the purchase order. McDATA shall acknowledge in writing
to EMC its receipt of such purchase order within [*] and acceptance or
rejection of such purchase order within [*] of McDATA's receipt of each
purchase order. For EMC purchase orders for quantities of Product(s) within
EMC's forecasts, McDATA shall accept such purchase orders at lead-time,
provided such purchase orders comply with the terms of this Agreement. If
within [*] from McDATA's receipt of a purchase order EMC does not receive
written notice from McDATA rejecting the purchase order and specifying the
reasons for such rejection, the purchase order shall be deemed accepted by
McDATA. In the event of a conflict between the provisions of this Agreement
and the terms and conditions of EMC's purchase order or McDATA's order
acknowledgment, the provisions of this Agreement shall prevail. Any
additional terms contained in EMC's purchase orders or McDATA's order
acknowledgements shall not be binding unless accepted by the other party in
writing.

7.2.1A MAKE AVAILABLE PROCESS (EMC DROP SHOP PURCHASE ORDERS). EMC shall issue
blanket purchase orders with scheduled [*] deliveries through lead-time. McDATA
will manufacture Products to a semi-finished goods state if actual Final
Configuration Releases are less than the purchase order quantity for the [*].
"FINAL CONFIGURATION RELEASE" means the EMC document that specifies the final
configuration of Products that McDATA shall ship in fulfillment of purchase
orders. The cancellation and reschedule terms detailed in 7.3.3A and 7.3.4A
shall apply to purchase order delivery dates. If Final Configuration Releases
are less than the purchase order quantities, then McDATA will hold such
semi-finished goods inventory until [*]. Prior to the end of each EMC fiscal
quarter, EMC shall provide Final Configuration Releases for all Products in
McDATA's inventory that were produced per EMC's purchase orders if EMC has not
already issued Final Configuration Releases and EMC has not cancelled or
rescheduled Products under the terms detailed below.

<Page>

The lead-time for Final Configuration Releases on all purchase orders covered
under this paragraph 7.2.1A will be [*] from the date EMC's Final Configuration
Release is issued. In some cases, EMC may request delivery sooner than the [*]
stated herein. In such cases, McDATA will make [*] to support these inside
lead-time requests.

7.2.2A CHANGE ORDERS TO SHIP ADDRESS. Except as provided above in Section
7.2.1A, EMC reserves the right to submit purchase change orders specifying
changes to the ship to address stated on such purchase order. McDATA agrees to
receive EMC's purchase change orders specifying changes in ship to address for
any Product at any time prior to [*] from scheduled date of shipment, and
provided all export documentation which is required to be supplied by EMC is
available on a timely basis, McDATA agrees to accommodate such change order. In
the event McDATA cannot satisfy any such change order to the ship to address
without impacting scheduled delivery, it will apprise EMC of the possibility of
delay and of the revised ship date within [*] of its receipt of such purchase
change order such that EMC can manage the situation with its customer.

7.2.3A LATE SHIPMENT. In the event EMC has submitted a purchase order for
Products or Spares in accordance with the terms hereof, and McDATA fails to ship
or ships late such Products or Spares, or partial shipments thereof, EMC may
cancel or reschedule such purchase order, or portion thereof, [*].

7.3A LEAD-TIME, UPSIDE SUPPORT SUPPLY, RESCHEDULING AND CANCELLATION.

7.3.1A LEAD-TIME. Lead-time for all Purchase Orders covered under this Agreement
will be [*]. In some cases, EMC may request delivery sooner than the [*]
lead-time stated herein. In such cases, McDATA will make [*] effort to support
these inside lead-time requests and will notify EMC in writing of any pass
through expediting costs relating thereto. McDATA shall not proceed with such
inside lead time request until the parties mutually agree in writing that EMC
will pay for such pass through expediting costs.

7.3.2A UPSIDE SUPPORT SUPPLY. McDATA agrees to manage its supply chain to meet
the upside quantity commitment(s) stated below. McDATA will confirm commitment
to support upside requirements for EMC within [*] of receipt of EMC's written
request for such upside quantities as provided to McDATA by a supporting
purchase order or purchase change order stating supplemental upside quantities,
delivery dates and reference to the Original Purchase Order.

7.4A QUARTERLY MATERIAL STATUS REPORT. Prior to the end of the [*], McDATA shall
provide EMC with an update to Exhibit A-4, Material Status Report.

7.5A PURCHASE ORDER NUMBERS. Purchase order numbers shall be referenced on all
correspondence, invoicing, and packing slips relating to each order.

7.6A   SPARES.

7.6.1A SPARE PARTS ORDERS. EMC has full responsibility for stocking Spares at
levels sufficient to satisfy its Reseller and End User Customer requirements.
Prices for Spares shall be those set forth on Figure A-5 of Exhibit A. As
outlined in McDATA's Spares, Repair and Upgrade Catalog attached hereto as
Figure A-5 of Exhibit A, Spares to support Products currently in production may
be ordered from 8:00 to 5:00 MT in two ways: "NORMAL SPARES" and "EMERGENCY
SPARES". Subject to EMC providing McDATA a forecast for Spares, orders for
Normal Spares shall be placed by EMC [*]. In the event EMC submits purchase
orders for Normal Spares which are outside the then-current forecast, McDATA
agrees to accommodate such changes and ship such Spares [*]. In the event EMC
requires a shorter lead-time than [*], McDATA will use [*] to first satisfy such
requirement [*]. If McDATA is unable to satisfy the shorter lead-time
requirement for such Spares order from [*], McDATA shall satisfy such Spares
order with Emergency Spares at prices stated in Figure A-5 of Exhibit A. McDATA
shall use [*] to ship order for Emergency Spares within [*] after receipt of
order. Spares to support discontinued Products shall be handled in accordance
with the provisions of the applicable Product discontinuance notice.

7.6.2A OTHER VENDORS. Nothing contained herein shall prohibit EMC from
purchasing Spares or replacement parts from any other vendor, provided, however,
that McDATA shall have no warranty responsibility with respect to such Spares
purchased from other vendor. This Agreement does not grant EMC a license to
purchase Spares that infringe any of McDATA's patent or other intellectual
property rights. Except as to Product failures caused by defective Spares
acquired from sources other than McDATA, the purchase and use by EMC of such
Spares or expendables (fuses and diskettes) acquired from sources other than
McDATA shall not affect McDATA's warranty responsibility for the affected
Products.




7.7A   SHIPMENT/DELIVERY AND EXPORT/IMPORT.

7.7.1A After appropriate export and import licenses are secured by McDATA, each
item of Product sold hereunder will be shipped [*]. EMC may specify the type of
conveyance and/or carrier for shipment. EMC shall also specify in writing, the
location to which the Products are to be shipped.

7.7.2A As used in this Agreement, shipment and delivery are synonymous. For
purposes of this Agreement, shipment and delivery occur upon delivery of
Products by McDATA at McDATA's factory to the common carrier specified by EMC.

<Page>

7.7.3A McDATA will provide the following information about its Product in
writing within [*] of receiving a written request from EMC: i) country of
origin; ii) NAFTA preference criteria (if applicable); iii) harmonized scheduled
tariff classification number, and iv) export commerce control number ("ECCN").
Upon EMC's request, McDATA, at its expense, will prepare all international
shipping documentation, including commercial invoice, NAFTA certificate,
Shipper's Letter of Instruction, Shipper's Export Declaration and any other
necessary documentation, for any international shipments of Product to be made
by or on behalf of EMC, provided the Product can be shipped to the requested
destination under a General License, validated license or other license under
the U.S. Export Administration Regulations. If a validated or other specific
prior license is required under the U.S. Export Administration Regulations, EMC
shall, on McDATA's request, provide sufficient information concerning the
destination and intended use for McDATA to obtain the export licenses and other
export documentation required. McDATA shall not be required to ship any Product
to any embargoed countries under the export control regulations of the United
States. In addition, McDATA will identify in Exhibit H any countries to which
Product may not be exported under any form of license under the U.S. Export
Administration Regulations, and shall update such Exhibit on EMC's request. EMC
shall not export or reexport any Product to any such country or countries.

7.7.4A Time and rate of delivery are of the essence of this Agreement. The
delivery dates shall be those specified in each purchase order issued under this
Agreement. Deliveries will be considered on time if they are shipped FOB
McDATA's Dock no more than [*] earlier or [*] days later than the delivery date
specified in the EMC purchase order. If EMC agrees to take partial delivery of
any order, each such partial delivery shall be deemed a separate sale

7.7.5A If McDATA anticipates or becomes aware that it will not supply the
Product on the delivery date acknowledged by McDATA, for any reason to include
but not be limited to material shortage, process changes, capacity limitations
or causes due to common carriers, McDATA shall notify EMC immediately after
McDATA has knowledge of the situation. The notification may be communicated by
facsimile, telephone, electronic mail or any other method agreed to by the
parties, provided that McDATA shall use [*] to obtain EMC's actual
acknowledgment of the notice of anticipated delay. McDATA and EMC will jointly
develop alternatives to resolve any late delivery of the Product, including use
of premium routing. McDATA will develop recovery plans with new committed
shipment dates and communicate such plans to EMC [*] of missed shipments and
provide written supply line delivery status and updates until resolved. If
McDATA is unable to deliver the Product on the acknowledged delivery date,
through no fault of EMC, EMC may require McDATA to pay the difference between
premium routing rates and standard routing rates. In the event McDATA has an
allocation situation, McDATA and EMC will agree on an allocation formula [*].

PURPOSE OF THE SPARES,
REPAIR, AND UPGRADE CATALOG
                           This catalog is designed to simplify the process of
                           ordering spares for your McDATA products. All spares
                           data has been organized and cross-referenced so that
                           information is easy to find. We hope that this format
                           will provide you with the service you require.

INFORMATION IN THE CATALOG
                           The Spares, Repair, and Upgrade Catalog contains two
                           types of information. The first section explains how
                           this catalog should be used, and gives details of
                           ordering procedures, return material authorization,
                           and repair and upgrade policies. The second section
                           consists of the spares price lists. Prices in this
                           catalog are subject to change.

SPARES PLANNING
                           McDATA expects customers who maintain their own
                           equipment to maintain spares inventories at an
                           appropriate level to support the requirements of
                           their specific field population. The primary
                           responsibility for planning and ordering for this
                           level of inventory rests with the buyer. Spare parts
                           are therefore priced according to the delivery lead
                           time allowed, i.e., the longer the lead time, the
                           lower the price.

ORDERING SPARES
                           To place an order for spare parts, or to request
                           advance replacement of a spare, contact McDATA Order
                           Administration or your Account Manager.

SPARES PRICING
The two categories of spares pricing are based on the delivery lead time
required:

NORMAL        [*] days or more lead time. This is the lowest price category.
                       EMERGENCY     [*] days lead time.

WARRANTY AND
RETURN MATERIAL AUTHORIZATION
                           All spares purchased are covered by a [*] warranty
                           from the date of shipment. McDATA agrees to accept
                           material returns for a period of up to [*] days after
                           the [*] year warranty period provided that McDATA is
                           notified in writing of the failure date of the
                           returned material. Notification of the failure date
                           is not required if the material is returned during
                           the warranty period. Please refer to your current
                           contract for any exceptions. Spares under warranty
                           may be returned to McDATA for repair, replacement or
                           credit by obtaining a Return Material Authorization
                           (RMA) number from the McDATA Customer Support
                           department. Expendable items may not be returned.

ADVANCE REPLACEMENT
OF SPARES POLICY
                           Should you so request, and given the availability of
                           the requested part, McDATA will ship a spare part in
                           advance of receipt of the failed part with the same
                           part number. You will be issued an RMA number for the
                           return of the failed part. Contact Order
                           Administration to order the needed material.

                           Upon shipment, McDATA will generate an invoice at the
                           "Emergency Spares" price in the current Spares,

RMA TURNAROUND TIMES
                           The estimated RMA turnaround times to process
                           returned material are shown on the time table listed
                           below. These schedules represent the time from the
                           receipt of the returned material at McDATA to the
                           shipment date from McDATA.

                                    o        PARTS       21 days (standard)
                                                         5 days (expedite -
                                                         additional fee applies)

FACTORS THAT AFFECT
RMA TURNAROUND TIMES
                           The above turnaround times may be affected when
                           approval from the customer is required in cases of
                           receiving discrepancies or when an estimate is
                           involved. In either of these situations, the
                           turnaround is calculated from the time approval to
                           proceed is received from the customer.

                           A delay may also occur when large quantities of
                           materials are forwarded simultaneously. To prevent
                           such a delay, McDATA recommends that materials be
                           returned in quantities of ten or less items at one
                           time when possible, and that problem descriptions are
                           attached to each part that is returned.

DISCREPANCIES
                           Any discrepancies between the materials received and
                           the materials listed on the RMA, or discrepancies
                           related to the condition of the materials received
                           will affect McDATA's ability to turn the material
                           around in a timely manner. Examples of discrepancies
                           are:

                                    o        Differences in part numbers or
                                             serial numbers
                                    o        Improperly packaged materials,
                                             resulting in damaged parts
                                    o        Unauthorized modifications to the
                                             parts
                                    o        Incomplete FRUs (for example:
                                             cables missing from power supplies)
