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

<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

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.

                                        7
<PAGE>   11
McDATA's sole obligation under this warranty shall be to repair or replace any
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 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
McDATA shall, and each Product delivered under this Development Agreement shall,
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

Except as specifically authorized in this Development Agreement, each party
acknowledges and agrees that it will not make any representations or warranties
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


                                        8
<PAGE>   12
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 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 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.



                                       10
<PAGE>   14
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 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.

each party will vote independently of the other party.

10.7  FORCE MAJEURE. Neither party shall be responsible for any failure to
perform or delay in performing any of its obligations due to causes beyond the
reasonable control of the party, including but not limited to acts of God, war,
riot, embargoes, acts of civil or military authorities, fire, floods, accidents,
strikes, or shortages of transportation, facilities, fuel, energy, labor, or
materials. In the event of such delay, either party may defer the performance
for a period equal to the time of such delay.

10.8  CONFLICT. If any provision of this Development Agreement is finally held
by a court of competent jurisdiction to be illegal or unenforceable, or in
conflict with any law having jurisdiction over this Development Agreement, the
validity of the remaining portions or provisions hereof shall not be affected
thereby.

Each PRODUCT will go through the phases outlined below. These phases are
outlined for the purpose of determining EMC and McDATA responsibilities.

                  2.0.1    CONCEPT EXPLORATION PHASE

                           This phase is used to scope the interdependencies of
                           various pieces of Product and complete the initial
                           design and specification work for the development of
                           Product. It will result in initial requirements.

                  2.0.2    REQUIREMENTS PHASE

                           This phase is used to define and document EMC's
                           Detailed Requirements for McDATA's Product.

<PAGE>   30
                  2.0.3    DESIGN PHASE

                           This phase is used to complete the design effort and
                           produce final versions of detailed requirements
                           documents and test plan.

                  2.0.4    IMPLEMENTATION PHASE (ALPHA)

                           This phase is used to develop and test of individual
                           components. Combine and test components as a
                           functionally complete product. The Product delivered
                           at the end of this phase is considered 'Alpha'.

                  2.0.5    INTEGRATION AND VERIFICATION PHASE

                           This phase is used to integrate McDATA's Product with
                           EMC hardware and software, including performance
                           analysis and tuning of McDATA's Product and target
                           operating system. Verification testing to ensure that
                           McDATA's Product meets their stated requirements. The
                           Product delivered at the end of this phase is
                           considered 'Beta'.

                  2.0.6    BETA PHASE

                           The Beta Phase starts upon delivery by McDATA of the
                           Beta version of McDATA's Product and ends with the
                           final acceptance of McDATA's Product by EMC. The Beta
                           Phase will be performed under responsibility of EMC.
                           EMC will provide technical support for EMC software
                           and hardware. McDATA will provide technical support
                           for Product.

                  2.0.7    GENERAL AVAILABILITY (GA)

                           Complete and close the Beta Phase. McDATA will
                           provide EMC with Product for EMC first article
                           acceptance testing.

2.1       PROGRAM MONITORING

Each of McDATA's Product will contain a more detailed description of the
McDATA's "Product Definition", used to identify project coordination contacts
and specify project deliverables of McDATA and EMC and their completion dates.
The appropriate Product Definition for each release of McDATA's Product,
together with the body of this document, will be the basis and guide for
conducting the Program Monitoring.

An initial version of the appropriate Product Definition will be created before
the start of each release. An updated version will be created upon completion of
