11
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, with no penalties.

Product lead-time shall be no more than [*] from receipt of EMC's purchase order
until shipment by McDATA to EMC.

7.2.2 Reschedule/Push-Out. EMC shall have the right and ability to

Upside will be released [*] unless committed to with firm released orders as
referenced in section 7.2.1.

7.2.4 EMC shall have the right to cancel delivery for any purchase
order without McDATA's consent, provided however, that McDATA must be notified
in writing of the cancellation at least [*]. In the event EMC cancels an order
more than [*] without re-booking a net new incremental order of the same or

scheduled delivery date, EMC shall be liable for the EMC unique material in
McDATA's pipeline as required to support EMC's forecast and purchase orders.
McDATA shall use commercially reasonable efforts to mitigate EMC's liabilities
for said unique material. If EMC cancels an order inside thirty (30) days of the
scheduled delivery date, EMC shall be liable for the full purchase price of the
cancelled Product.

7.2.5 Purchase Order Quantities in Excess of Forecast Quantities. If
any purchase order released by EMC specifies a quantity of Products in excess of
the quantity defined in the current forecast document, McDATA shall not be
obligated to deliver the excess quantity within the time period specified on
EMC's purchase order; however, McDATA shall use its best efforts to do so.

7.2.6 EMC may transmit purchase orders by facsimile. Orders are
considered binding upon receipt by McDATA of said facsimile, subject to
acceptance as set forth in 7.3 below.

7.2.7 Change Orders; Configuration Changes. For purpose of this
Agreement, a change order is EMC's notification to McDATA to release Product to
the Customer specified on the change order. McDATA agrees to receive EMC's
purchase change orders specifying changes in the configuration of any Product at
any time prior [*] from the scheduled date of shipment, and McDATA agrees to use
its best efforts to accommodate such change order, provided such change orders
do not reflect quantities in excess of the amounts ordered on the then-current
purchase orders In the event EMC's purchase change orders specify changes in the
configuration, and such

7
12
changes require quantities which are outside the then-current purchase order,
McDATA agrees to accommodate such changes and ship such Product on [*] within
[*] of such purchase change orders. McDATA agrees to receive EMC's purchase
change orders specifying changes in ship to address for any Product at any time
prior to [*] 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
without impacting scheduled delivery, it will apprise EMC of the possibility of
a 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.

7.3 ACCEPTANCE OF PURCHASE ORDERS. Purchase orders shall be considered as
accepted by McDATA unless McDATA provides EMC with written notice of any
discrepancy or the reason for rejection within [*] after receipt of such
purchase order. Unless EMC is in material breach of this Agreement, McDATA shall
not reject any purchase order which complies with the terms of this Agreement.
All such purchase orders shall be governed by the terms and conditions of this
Agreement, and none of the terms or conditions of EMC's purchase order or
McDATA's acceptance shall be applicable if they are in conflict with the terms
or conditions of this Agreement.

7.4 SPARES.

7.4.1 Spare Parts Orders. EMC has full responsibility for stocking
Spares at levels sufficient to satisfy its Reseller and End User Customer
requirements. As outlined in McDATA's Spares, Repair and Upgrade Catalog, 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 [*] 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 [*]. McDATA shall [*] to
ship orders for Emergency Spares [*]. Spares to support discontinued Products
shall be handled in accordance with the provisions of the applicable Product
discontinuance notice.

7.4.2 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 any other vendor. This Agreement does not grant EMC a license to
purchase Spares which 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.

8
13
7.5 SHIPMENT/DELIVERY AND EXPORT/IMPORT. After appropriate export and
import licenses are secured by McDATA, each item of Product sold hereunder will
be shipped FOB McDATA's Dock, Broomfield, CO. EMC may specify the type of
conveyance and/or carrier for shipment. EMC shall also specify in writing, at
least thirty (30) calendar days prior to the requested delivery date of such
Products, the location to which the Products are to be shipped.

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.

McDATA will provide the following information about its Product in writing
within two weeks 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.

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 Shipments will be considered on time if they are made no more than
three (3) business days earlier or no days later than the shipment date
specified in the EMC purchase order. If EMC agrees to take partial shipments of
any order, each such partial shipment shall be deemed a separate sale.

If McDATA anticipates or becomes aware that it will not supply the Product on
the shipment date stated on the purchase order, 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 obtain EMC's actual acknowledgment of the
notice of anticipated delay. McDATA and EMC will jointly develop alternatives to
resolve any late shipment of the Product, including use of premium routing. [*].
If McDATA is unable to ship the Product on the ship date stated on the purchase
order, through no fault of EMC, EMC's exclusive

9
14
remedy is for [*]. In the event McDATA has an allocation situation, McDATA shall
use an allocation formula for EMC [*].

8. PRODUCTS. McDATA agrees to sell to EMC the Products listed in Figure
A-1 and A-2 of Exhibit A of this Agreement, as it may be amended from
time-to-time, at the prices specified in Figure A-1 and A-2 of Exhibit A, and
under the terms specified in this Agreement. These prices are the maximum prices
and will not increase during the term of this agreement with the exception of
any agreed to increases pursuant to section 8.7.

8.1 PROCESS CHANGES.

Changes to McDATA's controlled manufacturing or repair
processes may be periodically reviewed by EMC, and any significant changes [*]
or the type of stress testing performed will be mutually agreed to in advance by
McDATA and EMC. Quality information on field and process performance will be
furnished to EMC on a monthly or quarterly basis.

8.2 PRODUCT DESIGN CHANGES AND FIELD MODIFICATION ORDERS.

8.2.1 Design Changes. In the event McDATA proposes a change to the
Products or Software which affects the form, fit or function of the Products and
such change will be implemented for all of McDATA's customers purchasing similar
products with similar specifications from McDATA, or if such change would
directly affect any EMC custom features, McDATA agrees to provide EMC prior
notification of such change, and give EMC an opportunity to comment on and
approve such change. On such notice, McDATA will state a date by which EMC's
comment and approval are required; such date shall be a minimum of [*] from the
date of such notice. If EMC has not responded on or before that date, McDATA
will assume EMC has no comments and approves such change, and will proceed with
the change process. If the changes proposed by McDATA in EMC's sole opinion
necessitate evaluation by EMC of compatibility with EMC's systems and/or
specifications, McDATA, upon EMC's request, shall provide EMC with an agreed
upon amount of evaluation products, parts or designs which incorporate the
proposed changes. EMC shall have the right to accept, reject or mutually agree
to an alternate plan for McDATA's proposed changes and will inform McDATA of its
approval or rejection of those changes in writing within [*] from the receipt of
the evaluation products, parts or designs provided to EMC, or [*] of EMC's
receipt of notice of such changes, whichever is later. In any event, EMC's
approval shall not be unreasonably withheld. If EMC rejects the changes, EMC may
require McDATA to continue supplying the unaltered Product or to provide EMC
with opportunities for a last time buy of the unaltered Product. For changes
accepted by EMC, McDATA will make field change kits necessary to install such
changes available to EMC within [*] after receipt of EMC's request for the kits.
Kits for Products may be purchased by EMC at McDATA's then current charge.

B. SOFTWARE:

(1). EMC grants to Customer a non-exclusive, non-transferable license to use the
Software solely in conjunction with the Designated EMC System or Host CPU, as
applicable, for which the Software was licensed.

(2). Customer shall not, without EMC's prior written consent, provide, disclose
or otherwise make available Software in any form to any person other than
Customer's employees, independent contractors or consultants, who shall use the
Software solely for Customer's internal business purposes in a manner consistent
with this Agreement. Customer shall be fully responsible to EMC for the actions
of its employees, independent contractors and consultants.

(3). Customer may make one copy of the Software for back-up and archival
purposes for use only in the case of a malfunction of Software, EMC Designated
System or Host CPU, as applicable.

Designated EMC System or Host CPU upon which the licensed Software is used to a
replacement location. If Customer moves the Software to another Designated EMC
System or Host CPU which has a different model number than the originally
Designated EMC System or Host CPU, Customer agrees to pay, if applicable, an
upgrade fee based on EMC's then-current price and upgrade policy and, at the
next support anniversary date, agrees to pay applicable fees based upon the
replacement model number.

(5). If Customer is granted a license to use Software in conjunction with a
Statement of Work (a "Project License"), Customer shall have a non-transferable
right to use the Software only for the purpose of conducting a specific project
under such Statement of Work. The Project License term shall be for one (1) year

malfunction or initiation of a disaster recovery program or is otherwise not
able to use the Enterprise Storage Software.

(7). Ownership: No title to, or ownership of, the Software is transferred to
Customer, and any references to "sale" or "purchase" of the Products, with
respect to the Software, shall be deemed to mean "license on the terms contained
in this Agreement." Customer shall reproduce and include EMC's copyright and
other proprietary notices on and in any copies, including but not limited to
partial, physical or electronic copies of the Software. Neither Customer nor any
of its agents, independent contractors or consultants shall modify, enhance,
supplement, create derivative works from, reverse assemble, reverse engineer,
reverse compile or otherwise reduce to human readable form the Software without
EMC's prior written consent. If Customer requires access to the source code of
the Software in order to achieve interoperability of the Software with other
software in the European Union or Norway, Customer shall provide EMC with
written notice. EMC can then decide either: (i) to perform the work in order to
achieve such interoperability and charge EMC's then-current rates for such work
to Customer; or (ii) to permit Customer to reverse engineer parts of the
Software in order to obtain such source code, but only to the extent necessary
to achieve such interoperability. Customer shall promptly report to EMC any
violation of this clause and shall take such further steps as may be reasonably
requested by EMC to remedy any such violation and to prevent future violations.

(8). Secondary Purchaser: Customer's right to use the Software may not be
assigned, sublicensed or otherwise transferred; provided however, that if
Customer sells or transfers the Designated EMC System, EMC shall offer to
license the Core Software and to render Equipment and Core Software Product
Maintenance to any bona fide end user (hereinafter "Secondary Purchaser") to
whom Customer has transferred the Designated EMC System pursuant to EMC's
then-current standard terms and conditions, so long as such Secondary Purchaser
is not deemed, in EMC's reasonable discretion, to be a competitor of EMC's.

the foregoing, payment for Training Services for courses offered through EMC's
course catalog shall be made prior to the start of the course.

(6). Security Interest: Customer hereby grants to EMC a purchase money security
interest in Equipment and Software purchased or licensed by Customer and all
proceeds thereof for the full amount of the purchase price and any costs and
charges incurred by EMC in connection therewith. At EMC's request, Customer
shall sign any documents, including one or more financing statements, and take
any other action required by law to perfect the security interests that may be
granted hereunder. Upon full payment by Customer, such security interests and/or

(1). If Customer notifies EMC promptly in writing of any action (and all prior
related claims) brought against Customer alleging that Customer's sale, use or
other disposition of any Equipment, Customer's use of any Software or its
receipt of any Service infringes a valid United States patent or copyright, EMC
will defend that action at its expense and will pay the costs and damages
awarded against Customer in the action, provided (i) that EMC shall have sole
control of the defense of any such action and all negotiations for its
settlement or compromise and (ii) Customer provides all reasonable assistance
requested by EMC. If a permanent injunction is obtained in such action against
Customer's use or receipt of such Product or if in EMC's opinion such Product is
likely to become the subject of a permanent injunction, EMC will at its option
and expense either procure for Customer the right to continue using or receiving

based on (i) use, sale or receipt of any of the Products in combination with
other equipment, software or services not provided by EMC; (ii) use of any of
the Products in a manner or for a purpose for which they were not designed;
(iii) use of the Software, when use of a Software Release which EMC has made
commercially available would have avoided such infringement; (iv) any
modification to any of the Products not made by EMC, or any modifications to any
of the Products made by EMC pursuant to Customer's specific instructions; or (v)
any intellectual property right owned or licensed by Customer or any of its
Affiliates.
