                  such new trademark and/or trade name, and stop using the
                  previous trademark and/or trade name, and if so instructed by

      13.1  MCDATA INDEMNIFICATION. McDATA agrees to indemnify, defend and hold
            Reseller harmless from any and all damages, liabilities, costs and
            expenses finally awarded against Reseller as a result of any third
            party claim, judgment or adjudication against Reseller (a) which
            claims that Products or Software infringe any patent, copyright,
            trademark, trade secret, or other intellectual property right of any
            third party in the United States, Canada, Mexico, Japan, Australia,
            New Zealand, Singapore, Brazil, United Kingdom, Germany, France, and
            other European Union member countries, or (b) for damage to property
            and tangible personal property or bodily injury (including death)
            caused by the Products or Software or McDATA's negligence or willful
            misconduct. As a condition of McDATA's obligation described in this
            Section 13.1, Reseller must promptly notify McDATA in writing of the
            claim, and cooperate with and grant to McDATA the sole control of
            the defense of any action and all negotiations for settlement and
            compromise. McDATA shall not be obligated to indemnify Reseller for
            any claim based upon (x) any alteration or modification made to the
            Product or Software unless made pursuant to McDATA's instructions,
            where such infringement, damage or injury would not have occurred
            but for such modification or alteration, and (y) any improper
            installation, storage, handling or use of the Products or Software
            not conforming to McDATA's published specifications by Reseller or
            its Channel Partners or End User Customers.

            In order to realize the worldwide intent of this Agreement as
            referenced in Section 6 above, and subject to Reseller's prior
            written notification of no less than thirty (30) days of its intent
            to sell Products or Software into additional countries not listed in
            subsection (a) above, the parties shall mutually agree to extend the
            above indemnification to such additional countries within thirty
            (30) days of such request. McDATA's agreement to extend the above
            indemnification of Reseller to such additional countries shall not
            be unreasonably withheld.

            In the event the Products or Software 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 Software, (ii) modify the
            Product or Software so that it is no longer infringing, or (iii)
            replace the Product or Software with a

            solution that is functionally equivalent, or (iv) refund to Reseller
            at the End User Customer's net book value for the Product.

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

      13.2  RESELLER INDEMNIFICATION. Reseller agrees to indemnify, defend and
            hold McDATA harmless for claims (a) made against McDATA by third
            parties for damage to real property and tangible personal property
            or bodily injury (including death) arising out of Reseller's misuse
            of the Products and/or Reseller's negligence or willful misconduct
            and for which Reseller is legally liable, and (b) based upon
            misrepresentation by Reseller in conducting its activities under
            this Agreement.

14    CONFIDENTIALITY OF INFORMATION. McDATA and Reseller acknowledge that in
      the course of purchasing Products and meeting their respective obligations
      under this Agreement, each may be obliged to obtain information relating
      to the Products and to each other which is of a confidential or
      proprietary nature and which is marked as such ("McDATA Proprietary
      Information" or "Reseller Proprietary Information" or equivalent). 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.
      McDATA and Reseller agree that to the extent that exchanges of Proprietary
      Information are necessary, any such exchange will be disclosed pursuant to
      the terms and conditions of that certain Confidential Disclosure Agreement
      No. 011898MCD dated March 31, 1998. Except as otherwise set forth herein,
      all information exchanged under this Agreement will be deemed to be
      non-confidential.

            Either party may publicly disclose the existence of this Agreement
            subject to prior review and approval by the other party; however,
            neither party shall disclose the specific terms and conditions to
            any third parties except by written agreement between McDATA and
            Reseller dated subsequent to the Effective Date, or as required by
            law or the order of a court of competent jurisdiction. This
            restriction in no way limits McDATA's ability to use the general
            form of this Agreement with other Resellers.

15    LIMITATION OF LIABILITY. EXCEPT FOR McDATA'S LIABILITY FOR INFRINGEMENT
      UNDER SECTION 13.1 AND EXCEPT FOR BREACH BY EITHER PARTY OF SECTION 14, IN
      NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY INDIRECT,
      SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF
      ANTICIPATED REVENUE OR LOSS RESULTING FROM BUSINESS DISRUPTION) ARISING IN
      CONNECTION WITH THIS AGREEMENT, WHETHER IN AN ACTION FOR CONTRACT OR TORT
      AND WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
      DAMAGE AND FOR ACTUAL DIRECT DAMAGES IN EXCESS OF [*].

            Neither party will bring any legal action against the other more
            than one (1) year after the cause of action arose.

16 TERMINATION.

      16.1  In addition to any other rights or remedies which may be available
            at law or in equity, either party may terminate this Agreement upon

            (i)   If either party is in default of any material provision of
                  this Agreement and such default is not corrected within thirty
                  (30) days of receipt of written notice specifying the nature
                  and extent of the breach of the other party, this Agreement
                  may be terminated by the party not in default. If the default
                  is such that it cannot be reasonably cured within thirty (30)
                  days, then the defaulting party must commence cure within
                  thirty (30) days and proceed to cure with due diligence. The
                  written notice shall state the defaults and the effective date
                  of termination if the defaults are not cured.

            (ii)  In the event of proceedings in bankruptcy or insolvency
                  invoked by or against either party, or in the event of the
                  appointment of an assignee for the benefit of creditors or a
                  receiver, the other party may elect to immediately terminate
                  the Agreement by providing written notice of its election to
                  terminate.

      16.2  Termination of this Agreement shall not relieve either party of the
            obligations incurred under this Agreement pursuant to Sections
            3.2.1, 10.7, 10.8, 11.1, 11.3, 12.3, 12.5, 13, 14, 17.4, 17.6, 17.8
            and Exhibit B, which Sections shall survive such termination. In
            addition, any other obligations under this Agreement which by their
            nature extend beyond the expiration date or other termination of
            this Agreement shall survive and remain in effect until all such
            obligations are satisfied.

      16.3  Upon termination of this Agreement by McDATA or by Reseller, each
            party shall return all of the other's tangible confidential
            information, prototypes and loaned equipment provided in connection
            with this Agreement, except as set forth in Section 14, within sixty
            (60) calendar days. The provisions of the confidentiality agreement
            shall survive termination of this Agreement.

            of, or damage to, your Product while it is in our possession or in
            transit in those cases where we are responsible to the

            performance, reliability or safety of a Product ("Field Change
            Orders" or "FCOs").

      3.2   Services will not include repair or replacement of any Product

            (a) which has been damaged by misuse, accident, modification,
            unsuitable physical or operating environment, or improper
            maintenance by you;

            (b) which has been used in combination with other equipment or
            software which are not recommended for use with such Product in
            McDATA's written specifications;

            (c) which has been moved, installed, deinstalled, altered or
            repaired by anyone other than McDATA or McDATA's authorized

            limitations described above, you agree to pay McDATA for such
            services at our then-current Time and Materials rates.

            connection with the Products are routinely archived and documented;

            notify McDATA in writing ninety (90) days prior to the relocation
            date. Upon receipt of such notification, McDATA may, at its option,

                  greater of [*] or the annual fees paid by you for Services.

            This limit also applies to any of our subcontractors. It is the
            maximum for which we and our subcontractors are collectively
            responsible.

      Under no circumstances are we or our subcontractors liable for any of the
      following:

7.1 FORECASTS. Within [*] EMC will give McDATA a forecast in writing of its
projected purchases of Products and Spares for the [*] quantities are to be
identified by [*] . One or before the [*] thereafter, EMC will provide McDATA
with an updated forecast covering the projected purchases of Products and Spares
for the subsequent [*] period. 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.

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 with no less than [*] notice [*]. The reschedule
of delivery will be a maximum of [*]. 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.
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
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 [*] 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 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.

<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". 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.

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 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.

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.
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-related Mandatory Change, and
McDATA's reimbursement to EMC will be the above agreed upon time at EMC's
then-current internal service rate.

         8.2.3 Obsoleted Spares. In the event that McDATA shall have obsoleted
through Mandatory Changes any Spares, EMC shall have the right to return and
receive full credit for any inventory of such Spares. McDATA agrees to accept
[*] any such Spares provided the obsoleted Spares have not been damaged or
subjected to misuse and are returned to McDATA, in substantially the same
condition as received by EMC, [*] after date of notice from McDATA pursuant to
Section 8.2.1 hereof.

         8.2.4 Change Information. McDATA shall supply EMC on a quarterly basis
a summary of all applicable engineering change orders (ECOs) issued by McDATA
during the preceding period which affect the Products.

improved product, McDATA agrees to give EMC the right to purchase such new
model, options, features or improvements under the terms and conditions of this
Agreement, at prices mutually agreed to by McDATA and EMC in accordance with the
terms of this Agreement.

         8.3.1 Unless EMC specifically rejects such changes, each version of the
Product will possess at least the same features and functions, if not more, than
are offered by McDATA in the Product or similar standard product offered by
McDATA for the same server/host environment. Unless EMC specifically rejects
such changes, McDATA shall introduce all new non-exclusive features or functions
for the Product [*] the [*] in [*] for that [*].

         8.3.2 McDATA agrees to offer to sell all generally available product
features and functions to EMC as early as it does to any of its other customers.
McDATA warrants to EMC that the prices offered for such product do not exceed
those offered to other customers purchasing products similar or identical to the
products in like or lesser quantities and upon similar terms and conditions. If
during the term of this Agreement McDATA sells such similar products, for lower
prices or under pricing terms to any other customer(s) which are more favorable
than the terms provided to EMC hereunder, thereupon and thereafter EMC shall,
with regard to deliveries after the date of such sale, be offered the benefit of
such lower prices or other such pricing terms under the same terms and
conditions of said other customer(s). McDATA agrees to notify EMC of such lower
prices or other such pricing terms [*] after the sale to another customer. EMC
shall have the right to request an independent audit regarding the subject
matter of this section 8.3.

consultants who need to know such Proprietary Information to fulfill that
party's obligations under this Agreement or to operate, maintain, or support the

hereunder without the prior written consent of the other party, which consent
shall not be unreasonably withheld. It shall be deemed reasonable for either

materials. In the event of such delay, either party may defer the performance
for a period equal to the time of such delay.

16.8 CONFLICT. If any provision of this Agreement is finally held by a court of

Trustee and Administrator of said Escrow Agreement.

Within [*] after the announced general availability of any of the Products,
McDATA shall deposit with the Escrow Agent the most current production level of
the Escrow Material, as defined in the Escrow Agreement. Thereafter, McDATA
shall within [*] after the release of an update to the Products, deposit updated
Escrow Material with the Escrow Agent.

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.
(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

                                       44
<PAGE>   49
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.

period.
(3). Support Procedures: Customer shall designate in writing a reasonable number
of authorized contacts, as determined by Customer and EMC ("Support Contacts"),
who shall initially report 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

(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.

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

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

                                       47
<PAGE>   52
modify such Product so that it becomes non-infringing or pay Customer a refund

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.

either party may terminate Equipment and Core Software Product Maintenance for
failure of the other party to comply with the terms of this Agreement provided
that the terminating party has given thirty (30) days written notice specifying
the failure and the other party has not remedied such failure within such time.
EMC reserves the right to change the scope of Product Maintenance, provided that
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
comply with the terms and conditions of this Agreement and then fails to cure
such failure within thirty (30) days after receiving written notice thereof from
EMC. Upon notice of termination, Customer shall immediately cease to use all
copies of the terminated Software, and shall return or destroy the terminated
Software and all portions and copies thereof.
(3). Termination of Professional Services and Training Services:
(a). Suspension of Services: EMC may suspend without liability its performance
of the Professional Services and Training Services if Customer is in arrears of
any financial obligation to EMC.
(b). Termination Rights: If a party materially breaches the terms of this
Agreement in relation to a Statement of Work, the other party shall give the
breaching party written notice of such breach. If the breaching party fails to
cure such breach within thirty (30) days after notice thereof, then the
non-breaching party may terminate all Statements of Work. However, termination
of a Statement of Work does not terminate this Agreement. In addition, either
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.
(c). Payments Upon Termination: If Customer elects to discontinue any of the
Professional Services prior to the completion of the next milestone to be
achieved under a Statement of Work, Customer shall pay to EMC the next
outstanding milestone payment (and all prior milestone payments) on such
Statement of Work.
(4). Survival of Terms: Termination of this Agreement shall not prejudice any
rights or relieve any obligations of either party that have arisen on or before
the date of termination. EMC and Customer agree that Sections 3A, 4D, 6 B, C(4)
and (6), E, H, I, J, K, L, M, N (2) and O shall survive the termination of this
Agreement.
O. MISCELLANEOUS
         (1). ASSIGNMENT: Customer shall not assign this Agreement or any of its
rights or obligations hereunder without EMC's prior written consent. EMC may
assign this Agreement and its rights hereunder without Customer's prior consent:
(i) to any individual or business entity controlling, controlled by or under
common control with EMC; or (ii) to the purchaser of all or substantially all of
EMC's assets or stock, through merger, consolidation or otherwise.
Notwithstanding anything contained in this provision to the contrary, no later
than ten (10) days after shipment of Equipment, Customer may notify EMC in
writing of its designation of a leasing company to finance any Equipment through
a conventional equipment financing lease. In

                                       50
<PAGE>   55
connection therewith, EMC, Customer and the leasing company must sign a mutually
agreeable assignment agreement. If the foregoing notice is not received by EMC
within the specified ten-day period or such assignment agreement is not executed
within ten (10) days after such Customer's notice, then Customer shall pay the
purchase price and all applicable taxes on the due date stated in the original
invoice.
         (2). ENTIRE AGREEMENT: This Agreement is the complete statement of the
contract between Customer and EMC with respect to the Products. No modification
or amendment of this Agreement shall be binding unless it is in writing and
signed by authorized representatives of Customer and EMC. In the event of any
conflict or inconsistency between the terms of this Agreement and any Order, the
terms of this Agreement shall control and prevail.
         (3). GOVERNING LAW: This Agreement shall be governed, interpreted and
construed in accordance with, and any arbitration hereunder shall apply, the
laws of the Commonwealth of Massachusetts, USA, excluding: (i) its conflict of
laws rules and (ii) the United Nations Convention on Contract for the
International Sales of Goods.
         (4). ARBITRATION: Any dispute, controversy or claim arising out of or
relating to this Agreement or to a breach hereof, including its interpretation,
performance or termination, shall be finally resolved by arbitration. The
arbitration shall be conducted by one (1) arbitrator appointed jointly by EMC
and Customer or, if they cannot agree, by the President of the American
Arbitration Association ("AAA"). The arbitration shall be conducted in English
in accordance with the commercial arbitration rules of the AAA. The arbitration,
including the rendering of the award, shall take place in Boston, Massachusetts,
USA and shall be the exclusive forum for resolving such dispute, controversy or
claim. The decision of the arbitrator shall be binding upon the parties hereto,
and the expense of the arbitration (including without limitation the award of
reasonable attorney's fees to the prevailing party) shall be allocated as
determined by the arbitrator. The decision of the arbitrator shall be executory,
and judgment thereon may be entered by any court of competent jurisdiction.
Notwithstanding anything contained in this provision to the contrary, EMC shall
have the right to institute judicial proceedings against the other party or
anyone acting by, through or under such other party, in order to enforce the
EMC's rights hereunder through reformation of contract, specific performance,
injunction or similar equitable relief.
         (5). APPLICABLE TAXES: In addition to the charges due under this
Agreement, Customer is responsible and shall pay or reimburse EMC for all sales,
use, excise, withholding, VAT, personal property and other similar taxes, duties
or tariffs resulting from this Agreement, except for taxes based on EMC's net
income.
         (6). USE OF NAME: EMC may use Customer's name in lists of EMC's
customers.
         (7). SEVERABILITY: If any provision of this Agreement is held by a
court of competent jurisdiction to be unenforceable because it is invalid or in
conflict with any law of any relevant jurisdiction, the validity of the
remaining provisions shall not be affected.
         (8). EXPORT: Customer agrees to comply with all applicable United
States export control laws and regulations, and will obtain any export and/or
re-export authorization required under the Export Administration Regulations of
the US Department of Commerce and other relevant regulations controlling the
export of the Products or related technical data.
         (9). US GOVERNMENT DATA RIGHTS: The Software is "commercial computer
software" or "commercial computer software documentation." If Customer is a unit
or agency of the United States Government, then the United States Government's
rights with respect to the Software are

                                       51
<PAGE>   56
limited by the terms of this Agreement, pursuant to FAR Section 12.212(a) and/or
DFARS Section 227.7202-1(a), as applicable.

          (10). NOTICES: All notices to EMC shall be in writing, directed to EMC
at EMC's address indicated on the first page of this Agreement, to the attention
of EMC's Office of the General Counsel. All notices to Customer shall be in
