5. CREDIT AND PAYMENT TERMS.

5.1 PAYMENT. Terms of payment are [*]. Payment of an invoice shall not
constitute or imply acceptance of the Product or relieve McDATA of any
obligations assumed under this Agreement, nor prevent EMC from asserting any
other rights it may have under this Agreement. Each Product shipment shall be
invoiced by McDATA upon shipment, and paid for by EMC when due, without regard
to other scheduled deliveries. All prices and fees described in this Agreement
are in United States dollars and all payments hereunder shall be made in United
States Dollars (i) by electronic wire transfer for international shipments, or
(ii) by electronic wire transfer or check for domestic shipments.

6. TITLE AND RISK OF LOSS. Except as set forth in Section 4.2.3 with regard to
title to the Software, title to Products purchased by EMC and the risk of loss
or damage in the goods shall pass to EMC upon shipment.

7. FORECASTS, ORDERS, AND DELIVERY.

7.1 FORECASTS. [*]. Forecasts are EMC's good faith estimates of intended total
purchases of Products, and are not commitments to buy. Any commitments to buy
are only valid upon EMC's issuance of purchase orders as defined in Section 7.2
below.

7.2 PURCHASE ORDERS.

         7.2.1 Purchase Order Content, Lead-Time, Rescheduling and Cancellation.
EMC shall, from time to time, release purchase orders to McDATA for Products and
Spares based on its forecasted requirements. Purchase orders are EMC's
commitments to buy Products and Spares from McDATA. Such purchase orders shall
be in writing and identify quantity, model, EMC part number, shipping
destination, carrier, and shipment dates and prices.

EMC reserves the right, subject to the provisions of Section 7.2.7 herein, to
submit purchase change orders specifying changes in the original configuration
of any Product(s) or the ship to address stated on such purchase order.

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.

                                       6
<PAGE>   11

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 reschedule
any purchase order [*]. All notices of changes will be communicated in writing
or in some other communication acceptable to the parties.

7.2.3 Reschedule/Upside. EMC and McDATA shall mutually agree on upside
quantities and reasonable buffer stock amounts to be available for delivery to
EMC at the end of each calendar quarter as part of the forecasting process. [*]

         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 [*]. In the event EMC cancels an order more than
[*] without re-booking a net new incremental order of the same or greater
quantity for delivery within ninety (90) days of the originally 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 [*], and McDATA agrees to use its best efforts to accommodate
such change order, provided [*]. 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
<PAGE>   12

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". [*].

         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.

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. [*].

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

                                       9
<PAGE>   14

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 [*]. 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
[*]. 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 [*]. Kits for
Products may be purchased by EMC at McDATA's then current charge. McDATA will
incorporate changes accepted by EMC into Product on EMC's open purchase orders
and into Product going through McDATA's repair process at no charge.

McDATA shall have the right to make any other design changes to the Products
which do not affect the form, fit or function and do not affect an EMC custom
feature at any time prior to shipment. EMC shall have the right to review any
such change to ensure that such change does not affect the form, fit or function
of the Products.

         8.2.2 Field Modification Orders. To the extent that McDATA determines
that any Product in the field requires modification, and that such Product is
retrofitable, McDATA shall supply EMC with Field Modification Order (FMO) kits
for changes. Each FMO kit will include the necessary parts, instructions, and
documentation to assist EMC in the proper installation of such FMO kits. There
shall be no charge to EMC for Mandatory Change FMO kits; pricing for EMC
Initiated Change FMO kits shall be announced. Installation of such FMO kits
shall be EMC's responsibility.

If McDATA determines that a Mandatory Change shall be incorporated into some or
all previously shipped units and if such change is not retrofitable, McDATA
agrees, at its expense and option, to either rework or replace each
non-conforming FRU previously delivered to EMC; however, EMC is responsible for
removing and returning to McDATA each such non-conforming FRU (using the
procedures outlined in McDATA's "Spares, Repairs and Upgrade Catalog"), and
reinstalling the reworked or replaced unit.

         In the event such Mandatory Change is required for safety reasons, the
parties agree to discuss in good faith reimbursing a portion of EMC's costs for
replacing such non-conforming FRUs. The parties will mutually agree on the time
required to complete installation of such safety-

                                       10

EMC's goal is to provide our customers with the best enterprise storage
solutions in the industry. To this end, everyone in EMC's organization is
dedicated to providing the highest quality Equipment, Software and Services.

This master Agreement establishes a simplified yet comprehensive way of doing
business with EMC. First, this single Agreement covers all of EMC's Products --
not only the sale of Equipment, but also the licensing of Software and the
provisioning of Product Maintenance and Professional and Training Services.
Second, this Agreement eliminates the need for a separate agreement each time an
EMC Product is needed. All that is required is an Order which must reference the
Agreement Number.

Any Affiliate identified by Customer may also place an Order under this
Agreement. Customer agrees to be responsible for the actions and obligations of
such Affiliate.

Customer hereby acknowledges that Customer has read and understands this
Agreement and agrees to the terms and conditions stated herein. This Agreement
may only be amended by an addendum that is duly signed by both parties. Such an
addendum would only apply to a single order unless it clearly states otherwise.

6. GENERAL TERMS

A. ORDERS: Any Order must refer to the Agreement Number and must include
information necessary to complete the associated transaction.

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.

(4). Customer may, only after written notice to EMC, change the location of a
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
or the completion of the project, whichever occurs first.

                                       42
<PAGE>   47

(6). Customer shall not use the Software on any device other than the Designated
EMC System or Host CPU, as applicable, except that the Enterprise Storage
Software may be temporarily transferred to a replacement Designated EMC System
or Host CPU, as applicable (and deleted from the original Designated EMC System
or Host CPU) if the Designated EMC System or Host CPU is inoperable due to
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.
Whenever the Core Software is licensed to a Secondary Purchaser in accordance
with this Paragraph, EMC shall offer to provide de-installation services for
Customer and re-installation and certification for Equipment and Core Software
Product Maintenance for the Secondary Purchaser at EMC's then-current applicable
fees.

problems and receive support from EMC hereunder. A
change to the authorized Support Contacts by Customer must be submitted in
writing to EMC by one of Customer's duly authorized representatives.

(4). Software Releases: EMC shall provide Software Releases as part of Product
Maintenance. A Software Release does not include new Products. A Software
Release is treated as Software and is covered by the license to the original
Software.

(5). Alterations and Attachments: EMC does not restrict Customer from making
alterations or installing other products in or with the Equipment at Customer's
expense, but Customer will be responsible for any inspection fees and/or
additional charges resulting from such activities; if the alterations or
attachments prevent or hinder EMC's performance of Product Maintenance, Customer
will, upon EMC's request, take appropriate action to facilitate EMC's
performance of Product Maintenance.

(6). Maintenance Aids: Maintenance Aids (including diagnostic tools) for aiding
the provision of Product Maintenance are owned by EMC and provided at Customer's
site for use by EMC's personnel. Customer agrees to use its best efforts to
prevent the unauthorized use or disclosure of Maintenance Aids. Customer will
not allow copies to be made of any Maintenance Aids. Customer further agrees to
allow EMC, upon reasonable notice, to enter the Designated Site(s) to remove
Maintenance Aids. Nothing hereunder grants to Customer a license to make use of
Maintenance Aids in any way.

(7). Replacement Parts: All Equipment and Software (or parts thereof) that are
replaced under Product Maintenance shall be owned by EMC. Customer shall return
what has been replaced upon EMC's request.

Statement of Work upon invoice.

(5). General: Subject to credit approval by EMC, payment for Products is due net
thirty (30) days from the date of EMC's invoice. If payment is delayed, EMC may
charge Customer interest at a rate equal to the lesser of 1.5% per month or the
maximum lawful interest rate under applicable law from the due date until
payment is received by EMC. All payments shall be in US dollars. Notwithstanding
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
security filings shall be released.

F. DELIVERY: Delivery of Equipment and Software will be F.O.B. common carrier at
EMC's plants. Unless Customer instructs EMC to use a particular common carrier,
EMC will select a common carrier and arrange for shipment and insurance at
Customer's expense. At EMC's option, Software may be delivered via the internet
or by similar means.

G. ACCEPTANCE: Acceptance will occur for Equipment and/or Software to be
installed by EMC: (a) upon successful completion of EMC's standard acceptance
procedures to be performed by EMC during installation; or (b) thirty (30) days

omissions to act. Acceptance for other Equipment and/or Software not to be
installed by EMC shall occur seven (7) days after shipment by EMC of such
Equipment and/or Software.

H. PRODUCT CHANGES: EMC reserves the right, at its expense, to make changes to
the Products: (a) upon reasonable notice to Customer, when such changes do not
adversely affect interchangeability or performance of the Products; (b) when EMC
believes changes are required for purposes of safety or reliability; or (c) when
EMC is required by law to do so. Customer shall give EMC reasonable access to
the Products for such purpose; failure to permit EMC to effect these changes
shall allow EMC to terminate Product Maintenance for all affected Products
without liability and without refunding to Customer any fees already paid for
such Product Maintenance.

I. DOCUMENTATION: EMC will provide Customer with one (1) then-current end-user
manual set with each article of Equipment and Software shipped under this
Agreement. Additional manuals or updates may be obtained from EMC. Customer
shall have a non-exclusive, non-transferable right to use such documentation
only at the Designated Site for its own internal use. Customer shall have no
right (i) to permit any third party to access or use such documentation, or (ii)
to copy or create derivative works of such documentation, whether for Customer's
internal use or otherwise.

J. PATENT AND COPYRIGHT

(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
such Product, replace or modify such Product so that it becomes non-infringing
or pay Customer a refund based on a straight line depreciation of the price of
such Equipment and/or Software over five (5) years upon return of the Equipment
and/or Software to EMC or refund the unused amounts paid to EMC for discontinued
Product Maintenance, as the case may be.

(2). EMC shall have no liability to Customer if the alleged infringement is
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.

(3). THIS PATENT AND COPYRIGHT SECTION STATES EMC'S ENTIRE LIABILITY WITH
RESPECT TO ALLEGED INFRINGEMENTS OF PATENTS, COPYRIGHTS AND OTHER INTELLECTUAL
PROPERTY RIGHTS BY THE PRODUCTS OR ANY PART OF THEM OR BY THEIR OPERATION, USE
OR RECEIPT.

Customer receives at least ninety (90) days prior written notice of such
changes.

(2). Software Licenses:
EMC shall have the right to terminate without liability any of Customer's
licenses to the Software granted pursuant to this Agreement if Customer fails to

party may terminate all Statements of Work upon written notice if the other
party shall become insolvent or bankrupt or makes an arrangement with its
creditors or go into liquidation.

provided in Section 4.3 herein, the Product development and updates shall be
provided at no charge to EMC. This Development Agreement is non-exclusive and
the parties may enter into similar Development Agreements with other parties.
EMC and McDATA may enter into agreements concerning the purchase, license,
distribution and sale of the Products and updates from time to time. However,
EMC shall not be obligated to purchase any Products developed by McDATA
hereunder.

4.       INTELLECTUAL PROPERTY RIGHTS.

4.1 Subject to Section 4.2, McDATA grants EMC all appropriate rights and
licenses worldwide, at no additional charge beyond its price for the Products,
under McDATA's applicable patents, copyrights and other intellectual property
rights, as necessary for EMC to evaluate, test, demonstrate, support, maintain,
repair and upgrade the Product as provided under this Development Agreement.
Except as expressly herein stated, no other license is granted to EMC.

4.2      SOFTWARE LICENSE.

         4.2.1 McDATA hereby grants to EMC a non-exclusive, worldwide, revocable
(except as expressly provided in Section 4.2.4), royalty-free right and license,
under all copyrights, patents, patent applications, trade secrets and other
necessary intellectual property rights of McDATA, to (i) use, execute, and
display Software of McDATA used in the operation and support of the Product,
including upgrades, updates, bug fixes or modified versions or backup copies of
the same, in object code form, in conjunction with, or for use with Products,
and (ii) authorize, license and sublicense its employees and consultants to do
any, some, or all of the foregoing provided EMC

                                       3
<PAGE>   7

agrees (a) to operate and use the Software for its own internal business
purposes, in the form of object code only, without the right to further license
or sublicense, (b) not to reverse assemble, reverse compile, or reverse engineer
the Software in whole or in part, except as specifically permitted by law, and
(c) to require its employees and consultants, by a suitable agreement, to abide
by these license restrictions.

         4.2.2 EMC shall not have the right to (i) modify or adapt the Software
for other products or create derivative works of the Software, (ii) decompile,
reverse engineer, or disassemble the Software for purposes of designing similar
products, or (iii) use or distribute the Software other than in connection with
the use or distribution of the Products.

         4.2.3 EMC agrees that the foregoing licenses do not grant any title or
other right of ownership to the Software and that McDATA owns and shall continue
to own all right, title and interest in and to the Software.

         4.2.4 Upon any termination or expiration of this Development Agreement,
EMC's rights set forth in this Section 4.2 shall terminate.

4.3 As between EMC and McDATA, the rights in the Products are and will remain
the sole and exclusive property of McDATA and its vendors, if any, whether the
Products are separate or combined with any other products. McDATA's rights under
this Section, will include, but not be limited to (i) all copies of the Software
for the Products, in whole or in part; (ii) all intellectual property rights in
the Products; and (iii) all modifications to, and derivative works based upon
the Products. Notwithstanding the foregoing, EMC may request that certain
features be incorporated into the Products ("EMC Custom Features"). EMC agrees
to make such request in writing to McDATA. McDATA shall evaluate such request,
including the time and costs involved in the development of such EMC Custom
Features. In the event McDATA agrees to develop such EMC Custom Features, the
parties will negotiate in good faith whether or not non-recurring engineering
costs will be paid to McDATA, and if so, in what amount. Notwithstanding the
foregoing, nothing in this Development Agreement shall be construed to grant
McDATA any ownership rights in any "EMC Custom Features" incorporated into any
version of any of the Products. EMC Custom Features means any functionality,
APIs, source code or schematics which EMC wishes to incorporate into a version
of the Products and which McDATA agrees in writing to incorporate into the
Products. Any agreed upon EMC Custom Features will be incorporated into this
Development Agreement in Exhibit T or by a written amendment to Exhibit T, as
applicable. All EMC Custom Features shall be solely owned by EMC regardless of
inventorship, and shall not be included in any McDATA standard product other
than the Product without EMC's prior written consent.

4.4 EMC hereby grants to McDATA, and McDATA hereby accepts a royalty-free,
personal, worldwide, non-exclusive, non-transferable right and license to use
those EMC marks designated by EMC solely on Product and collateral materials
provided to EMC or on behalf of EMC. McDATA shall use EMC, the EMC logo, EMC's
brand name for the Product, and any other EMC mark only

                                       4
<PAGE>   8

during the term of this Development Agreement, only in connection with its
manufacture, distribution and support of the Product for EMC in accordance with
the terms of this Development Agreement, and only in accordance with EMC's
written guidelines for such usage. McDATA shall not use any such EMC marks in
connection with any business conducted by McDATA other than dealings with the
Products in accordance with the terms of this Development Agreement. McDATA
agrees that its use of the EMC marks shall not create in its favor any right,
title or interest therein and acknowledges EMC's exclusive right, title and
interest thereto. McDATA agrees that it will not use, without EMC's prior
written consent, any mark which is likely to be similar to or confused with any
of EMC's trademarks.

5.       PRODUCTS. McDATA agrees to develop the Products listed in Figure S-1
and S-2 of Exhibit S of this Development Agreement, as it may be amended from
time-to-time, in accordance with the specifications set forth in Exhibit T, and
under the terms specified in this Development Agreement.

5.1      PRODUCT SPECIFICATIONS.

         Specifications for the Products listed in Figure S-1 and S-2 of Exhibit

upon written request to McDATA specifying the same in detail. As soon as
practicable after receipt thereof, McDATA shall review the request and, if
acceptable to McDATA, shall furnish EMC price estimates, non-recurring
development costs, and delivery schedules for such changes or modifications. If
same are acceptable to EMC, McDATA will, upon receipt of a purchase order
therefor, proceed to implement same at the expense of EMC.

         If EMC desires to incorporate a EMC Initiated Change into some or all
previously shipped units, and if such changes are not retrofitable, McDATA shall
cooperate in incorporating such changes, provided that EMC shall bear all costs
and expenses associated with incorporating such changes.

<PAGE>   10

Products at the time of shipment. EMC shall not modify any regulatory agency
marks or labels affixed to the Products by McDATA. McDATA hereby disclaims any
liability for the possession, use, resale, or operation of any Products which,
as a result of an alteration by EMC or any third party (unless such third party
is a McDATA authorized third party service provider), affects its compliance
with the applicable regulations and/or requirements as stated above.

6.       WARRANTY

6.1 PRODUCT WARRANTY. McDATA warrants that the Beta Phase and GA Products (as
described in Exhibit U) (except Object Code Software) developed and provided to
EMC under this Development Agreement will, under normal use and service, conform

been damaged, subjected to misuse, altered, improperly repaired or maintained by
EMC or third parties in a manner which McDATA reasonably determines to have
adversely affected performance or reliability. McDATA's liability hereunder is
limited to the indemnification under Section 7.3 and the repair or replacement
of the defective Product, and if neither repair nor replacement is possible, a
refund of any monies paid for such non-conforming Product, and does not include
any labor related to the removal and/or subsequent reinstallation thereof.
Product may consist in part of used components which are warranted as equivalent
to new when used in the Product.

As mutually agreed upon, returns to McDATA will be transacted for credit only or
credit and replacement will be delivered at no charge to McDATA; returns to EMC
will be delivered at no charge to EMC.

The above warranty extends solely to EMC (and shall not be transferred or

Product warranty.

6.2 SOFTWARE WARRANTY. McDATA warrants that the Beta Phase and GA licensed
Object Code Software developed and provided to EMC under this Development
Agreement will, under normal use and service, substantially conform to Product
Specifications and be free from defects in material and workmanship for ninety
(90) calendar days from the date of first production of any version.

defective Object Code Software media and/or to remedy any non-conformance of the
Object Code Software to enable it to materially conform to the functional
specifications set forth in its applicable

                                       7
<PAGE>   11

documentation, and if neither is possible, a refund of the monies paid for such
non-conforming Product, and the indemnification under Section 7.3.

This warranty is only effective when the Object Code Software is used on or in
conjunction with the Product(s) to which it relates. Further, the warranties are
contingent upon proper use of the Object Code Software by EMC or EMC's
Customers, and will not apply if the Object Code Software has been modified
without the prior written consent of McDATA. McDATA makes no warranty that use
of the Object Code Software will be uninterrupted or error-free.

6.3 TITLE WARRANTY. Except as set forth in Section 4.2.3 with regard to title to
the Software, McDATA warrants that EMC shall receive good title to all Products
delivered to EMC under this Development Agreement free and clear of all liens,
encumbrances or other claims, and in performing under this Development Agreement

comply with all applicable country, state and local, laws, statutes, ordinances,
rules, regulations and codes. McDATA further warrants that each Beta Phase and
GA Product when shipped has been, and will continue to be regulatory compliant
as detailed in Exhibit T and X. Each Product shall bear appropriate labels
indicating compliance with the requirements of this Exhibit T. McDATA's sole
obligation and EMC's sole remedy for breach shall be repair or replacement of
non-conforming Product, at EMC's option, and if neither is possible, a refund of
the monies paid for such non-conforming Product and the indemnification under
Section 7.3.

6.4 DISCLAIMER. THE WARRANTIES AND CONDITIONS SET FORTH HEREIN AND THE
OBLIGATIONS AND LIABILITIES OF McDATA HEREUNDER ARE IN LIEU OF, AND EMC HEREBY
WAIVES, ALL OTHER EXPRESS OR IMPLIED WARRANTIES AND CONDITIONS, INCLUDING,
WITHOUT LIMITATION, THOSE OF MERCHANTABILITY AND/OR FITNESS FOR A PARTICULAR
PURPOSE

on behalf of the other.

7.       INDEMNIFICATIONS.

7.1 McDATA agrees to indemnify, defend and hold EMC harmless from any and all
claims, demands, suits, actions, judgements, damages, liabilities, costs and
expenses (including reasonable attorney's fees and costs) arising from any third
party claims brought or awarded against EMC that Products infringe any patent or
copyright, or trade secret, provided EMC promptly notifies McDATA in writing of
the claim, and grants to McDATA the sole control of the defense of any action
and all negotiations for settlement and compromise, but provided that EMC's
consent is required for any settlement that calls for payments in excess of the
liability cap specified in Section 9, such consent not to be unreasonably
withheld. EMC is entitled to be represented in any such action by its own
attorneys at its own expense. McDATA shall not be liable for any claim of

                                       8
<PAGE>   12

infringement to the extent that it is based upon any Product or Software which
is altered or modified without McDATA's authorization.

In the event the Products become, or in McDATA's opinion are likely to become,
the subject of an infringement, McDATA shall have the right, at its option and
expense, to (i) obtain the rights to continued use of such Product, or (ii)
replace or modify the Product so that it is no longer infringing, or (iii)
refund to EMC the price paid for the Product less a reasonable amount for use,
damage or obsolescence in accordance with a straight-line depreciation schedule
over a five (5) year life.

The foregoing remedies are the sole remedies for infringement of any
intellectual property rights.

7.2 EMC agrees to indemnify, defend and hold McDATA harmless from any and all
claims, demands, suits, actions, judgements, damages, liabilities, costs and
expenses (including reasonable attorney's fee's and costs) arising from any
third party claim brought or awarded against McDATA as a result of any claim,
judgment or adjudication against McDATA to the extent based upon any material
breach of this Development Agreement or misrepresentation by EMC in conducting
its activities under this Development Agreement, including without limitation
any claims relating to the modification of the Products by EMC or by third
parties that modified the performance or contents of the Products, provided that
McDATA promptly notifies EMC in writing of the claim, and grants to EMC the sole
control of the defense of any action and all negotiations for settlement and
compromise, but provided that McDATA's consent is required for any settlement
that calls for payments in excess of the liability cap specified in Section 9,
such consent not to be unreasonably withheld. McDATA is entitled to be
represented in any such action by its own attorneys at its own expense.

7.3 McDATA shall indemnify and defend EMC against all claims, suits, losses,
expenses and liabilities arising from any third party claim brought against EMC
alleging bodily injury, personal injury, death, and property damage directly
caused by the failure of any Product to conform to its specification or to any
applicable laws or regulations or through the negligence of McDATA or any person
for whose actions McDATA is legally liable, provided that, in either case (i)
EMC has notified McDATA promptly in writing of any such claims, (ii) McDATA
shall have sole control of the defense of such claims and all negotiations for
its settlement and compromise, provided that EMC's consent is required for any
settlement that calls for payments in excess of the liability cap specified in
Section 9, such consent not to be unreasonably withheld and (iii) EMC shall
reasonably cooperate with McDATA in the defense or settlement of such claims.
EMC is entitled to be represented in any such action by its own attorneys at its
own expense. McDATA shall carry and maintain Workman's Compensation and general
liability insurance coverage to satisfactorily cover McDATA's obligations under
this Section.

McDATA shall not be liable for any claims under Section 7.3 to the extent that
they are based upon any Product that has been damaged, submitted to misuse,
altered, improperly installed, repaired or maintained by EMC or third parties in
a manner which McDATA reasonably

                                       9
<PAGE>   13

determines to have adversely affected performance or reliability.

8.       CONFIDENTIALITY OF INFORMATION.

8.1 Both parties may, in connection with this Development Agreement, disclose to
the other party information considered confidential and proprietary information
of the disclosing party ("Proprietary Information"). Information shall be
considered Proprietary Information if identified as confidential in nature by
the disclosing party at the time of disclosure, or which by its nature is
normally and reasonably considered confidential, such as information related to
past, present or future research, development, or business affairs, any
proprietary products, Software, materials or methodologies, or any other
information which provides the disclosing party with a competitive advantage.
Such Proprietary Information may include, but is not limited to, trade secrets,
know-how, inventions, techniques, processes, programs, schematics, data,
customer lists, financial information, and sales and marketing plans. Each party
shall at all times during the term of this Development Agreement and for five
(5) years after its termination, keep in confidence and trust all such
Proprietary Information and shall not use such Proprietary Information without
the prior written consent of the other party, except (i) as permitted by the
terms of this Development Agreement, (ii) as may be necessary to fulfill its
obligations under this Development Agreement, and/or (iii) to operate, maintain,
or support the Products. Furthermore, neither party shall, without the prior
written consent of the other party, disclose such Proprietary Information to any
person except to those of its employees, Resellers, or consultants who need to
know such Proprietary Information to fulfill that party's obligations under this
Development Agreement or to operate, maintain, or support the Products, provided
that such employees, Resellers, or consultants are parties to written
Development Agreements with EMC such party to keep in confidence such
Proprietary Information; such Development Agreements will meet the minimum
requirements outlined in this Section 8.1 attached hereto, or versions thereof
adapted to Resellers, or consultants, in accordance with any applicable local
laws, and such party shall use reasonable commercial efforts to prosecute
material violations of such Development Agreements with respect to the
Proprietary Information.

It is understood that each party is not granting to the other party any rights
in the Confidential Information, and all right, title and interest in the
Confidential Information shall remain the property of the disclosing party.

Upon termination of this Development Agreement and upon request, the receiving
party shall, on a reasonable commercial efforts basis, promptly return all
Proprietary Information under its control and all copies thereof to the
disclosing party, except that the receiving party shall be permitted to retain
such copies of the Proprietary Information as are necessary to operate,
maintain, or support Products previously purchased pursuant to this Development
Agreement.

The non-disclosure provisions of this Section shall not apply to information
which (i) becomes publicly available through no act of the receiving party; (ii)
is required to be disclosed by the law

                                       10
<PAGE>   14

of any government which has jurisdiction over such information, provided that
the disclosing party is given prior notice of any such disclosure; (iii) was
previously known at the time of its receipt without similar restrictions; (iv)
is released by written mutual agreement of McDATA and EMC; (v) can be shown by
the receiving party to have been provided by the disclosing party to others
without similar restrictions; or (vi) can be documented, by adequate written
records, to have been independently developed by the receiving party without
reference to or use of any Proprietary Information.

8.2 McDATA will not originate, or authorize, assist or permit another party to
produce, any written publicity, news release, marketing collateral or other
publication or public announcement whether to the press, actual or potential
customers, stockholders, or others, relating to this Development Agreement, to
any amendment hereto or to performance hereunder or to the existence of an
arrangement between the parties without the prior written approval of EMC.
Notwithstanding the above, EMC shall not unreasonably withhold approval of
disclosure of the Development Agreement for the purpose of McDATA complying with
any SEC or legal regulations. The existence, terms and conditions of this
Development Agreement are considered EMC Confidential Information.

8.3 The parties agree that any violation of this or any other agreement covering
nondisclosure of Proprietary Information or publication or any unauthorized
disclosure of Proprietary Information shall constitute a violation of the terms
of this Development Agreement. Both parties acknowledge that it is the
responsibility of each party to take all reasonable measures to safeguard the
Proprietary Information to prevent its unauthorized use.

9.       LIMITATION OF LIABILITY.

EXCEPT AS TO McDATA's OBLIGATIONS UNDER SECTION 7.1 for intellectual property
infringement, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL,
INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS) DUE TO
FAILURE TO PERFORM ITS OBLIGATIONS IN CONNECTION WITH THIS DEVELOPMENT
AGREEMENT.

10.2 WAIVER. The failure of either party to insist upon or enforce strict
conformance by the other party of any provision of this Development Agreement or
to exercise any right under this Development Agreement shall not be construed as

waiver of any right or remedy on one occasion by either party shall be deemed a
waiver of such right or remedy on any other occasion.

10.5 ASSIGNMENT. Neither party shall assign this Development Agreement or any
rights hereunder without the prior written consent of the other party, which
consent shall not be unreasonably withheld. It shall be deemed reasonable for
either party to withhold consent to an assignment involving one of its
