13   INDEMNIFICATION

     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

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 the
          occurrence of any one of the following:

          (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

17 GENERAL PROVISIONS
     17.1 ENTIRE AGREEMENT. This Agreement, together with the documents and
          other agreements referenced herein are the final, complete, and
          exclusive agreement between Reseller and McDATA with respect to the
          subject matter herein. This Agreement takes precedence over any
          additional or different terms from whatever source, including those of
          Reseller, to which objection is hereby made by McDATA.

     17.2 WAIVER. No 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.

     17.3 CONTRACT CHANGES. Except as provided herein, this Agreement may not be
          modified or amended except by an instrument in writing signed by duly
          authorized representatives of both parties. The parties acknowledge
          that from time to time McDATA and Reseller may wish to implement
          changes to this Agreement.

     17.4 GOVERNING LAW. This Agreement shall be governed by the substantive
          laws of the State of New York. Any proceeding to enforce, or to
          resolve disputes relating to, this Agreement shall be brought before a
          court of competent jurisdiction in the State of New York, including a
          federal District Court sitting within such State. In such proceedings.
          neither party shall assert that a court lacks jurisdiction over such
          party or the subject matter hereof. The parties hereto expressly waive
          any right they might have to a jury trial and agree that any
          proceeding under this Agreement shall be tried by a judge without a
          jury. The United Nations Convention on the International Sale of Goods
          (CISG), as provided for in Article 6 thereof, is specially excluded
          and shall not be applicable to any transaction contemplated herein.

     17.5 SEVERABILITY. If any part of this Agreement is found to be invalid by
          any court, the remainder will remain in full force and effect.

     17.6 COMPLIANCE WITH LAWS. The parties as well as Channel Partners shall
          comply with all applicable laws, including, without limitation, the
          import and export control laws of the United States of America, any
          import and export control regulations of the United States, and any
          applicable laws or regulations of those countries involved in
          transactions concerning the exporting, importing and re-exporting of
          Products purchased under application of these terms and conditions.
          The parties as well as Channel Partners shall also comply with the
          United States Foreign Corrupt Practices Act and shall indemnify McDATA
          from and against any liabilities, damage, costs and expenses,
          including reasonable attorneys' fees with respect to claims resulting
          from violations of such act by a party and/or a Channel Partner.

          Reseller covenants to McDATA that it shall not export from the United
          States or reexport from the country to which McDATA initially exports
          any of the Software in any form, without the prior written consent of
          McDATA and any agency of the United States government where such
          consent is necessary.

          deemed given when transmitted by facsimile (provided such facsimile is

          you agree to ship the Product suitably packaged (prepaid unless we
          specify otherwise) to a location we designate. After we have repaired
          or exchanged the Product, we will return it to you at our expense
          unless we specify otherwise. We are responsible for loss of, or damage
          to, your Product while it is in our possession or in transit in those
          cases where we are responsible to the transportation charges.

          McDATA will install engineering changes which improve the performance,

     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

     (d)  properly care for the Products, as specified in the documentation for
          the Products, including maintaining a proper site environment
          (temperature, humidity, power, etc.);

     (e)  ensure that all of your Product software and data files used in
          connection with the Products are routinely archived and documented;

     (f)  if, during the contract term(s), you wish to relocate Product(s) from
          the initial installation site to a new location, you agree to notify
          McDATA in writing ninety (90) days prior to the relocation date. Upon
          receipt of such notification, McDATA may, at its option, prepare the
          Products for such relocation, and reinstall the Products at McDATA's
          then-current rates.

5    WARRANTY FOR SERVICES. McDATA warrants that we will perform the Services
     using reasonable care and skill. THIS WARRANTY AND THE APPLICABLE WARRANTY

     LIMITATION THE IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY AND
     FITNESS FOR A PARTICULAR PURPOSE.

6    LIMITATION OF LIABILITY
     6.1  Circumstances may arise where, because of a default on our part or
          other liability, you are entitled to recover damages from us. In each
          instance, regardless of the basis on which you are entitled to claim
          damages from us (including fundamental breach, negligence,
          misrepresentation, or other contract or tort claim), we are liable for
          no more than:
          (a)  damages for bodily injury (including death) and damage to real
               property and tangible personal property; and
          (b)  the amount of any other actual direct damages up to the 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.

     6.2  ITEMS FOR WHICH WE ARE NOT LIABLE
     Under no circumstances are we or our subcontractors liable for any of the
     following:
          (a)  third party claims against you for damages (other than those
               under Section 6.1 (a) above);
          (b)  loss of, or damage to, your records or data; or
          (c)  special, incidental, or indirect damages or for any economic
               consequential damages (including lost profits or savings), even
               if we are informed of their possibility.

thirty (30) days of written notice, SCI may dispose of the property at its
convenience without liability or accounting.

15.      TERMINATION AND CANCELLATION

15.1     MCDATA'S DEFAULT. The failure by McDATA to make any payment required
hereunder, or a material breach by McDATA of its obligations hereunder, shall
constitute an event of default by McDATA. Upon the occurrence of an event of
default by McDATA, SCI shall provide McDATA with written notice specifying the

<PAGE>   11

15.2     SCI'S DEFAULT. A material breach by SCI of its obligations hereunder
shall constitute an event of default by SCI. Upon the occurrence of an event of
default by SCI, McDATA shall provide SCI with written notice specifying the
nature of such default. In the event SCI fails to remedy such default within
thirty (30) days after receipt of such notice, McDATA may, at its sole option,
cancel this Agreement and/or seek any other remedies available under law or in
equity.

15.3     INSOLVENCY. In the event of proceedings (voluntary or involuntary) in
bankruptcy or insolvency by or against either party hereto, or in the event of
the appointment (with or without the party's consent) of an assignee for the
benefit of creditors or a receiver, the opposite party may elect to immediately
terminate this Agreement.

15.4     CANCELLATION. Either party may cancel this Agreement at any time,
without cause or liability, by providing [*] advance written notice to the other
party. In the event that McDATA cancels this Agreement and SCI has procured
material, authorized by McDATA, in excess of the quantity required to
manufacture the Products scheduled during the [*] notification period, McDATA
agrees to purchase such unused material at the then current agreed upon material
cost plus [*] handling charge, at the time of the last delivery of Product.

16.      GENERAL.

16.1     ENTIRE AGREEMENT; AMENDMENT. Except as may be otherwise provided in
this Agreement, this Agreement constitutes the entire agreement between SCI and
McDATA and supersedes all previous understandings, negotiations and proposals,
whether written or verbal. This Agreement may not be altered, amended or
modified except by an instrument in writing signed by duly authorized
representatives of each party. In the event that any one or more provisions
contained in this Agreement should for any reason be held to be unenforceable in
any respect, such unenforceability shall not affect any other provisions hereof,
and this Agreement shall be construed as if such unenforceable provision had not
been contained herein.

16.2     TERMINATION. Neither party may terminate this Agreement except as
specifically provided for herein. Such termination shall not relieve either
party of such obligations as are intended to survive the termination, including

16.3     FORCE MAJEURE. Neither party shall be liable to the other for delays or
failures to perform any obligation hereunder if such delay or failure to perform
is due to any act of God, acts of the other party, acts of civil or military
authority, labor disputes, fire, riots, civil commotions, sabotage, war,
embargo, blockage, floods, epidemics, delays in transportation, or when due to
governmental restrictions. In the event of any such delay or failure, the
parties shall have an additional period of time equal to the time lost by reason
of the foregoing in which to perform hereunder.

16.4     GOVERNING LAW. This Agreement shall be governed in all respects by the
laws of the State of Colorado, U.S.A., as such laws are applied to agreements

This Addendum is entered into by McDATA Corporation ("McDATA"), having its
principal place of business located at 310 Interlocken Parkway, Broomfield,
Colorado, 80021-3464, and SCI Systems, Inc. ("SCI"), 5525 Astrozon Blvd.,
Colorado Springs, Colorado 80916-4226.

WHEREAS, McDATA and SCI have entered into Manufacturing Agreement 01-92-03-0A
executed in full and effective 16 June 1992;

WHEREAS, McDATA and SCI have mutually agreed to enter into additional agreements
and alterations to this agreement as part of an enlargement to the business
relationship;

WHEREAS, McDATA and SCI have agreed to restate certain portions of said
agreement for clarity;

WHEREAS, McDATA desires to contract for SCI's services in manufacturing the
products as listed in the revised Exhibit A hereto;

WHEREAS, McDATA and SCI agree that the provisions of this Addendum will take
precedence over the original agreement in the event of a conflict;

NOW THEREFORE, the aforementioned agreement is amended and the parties hereto
agree as follows:

First: Delete Paragraph 3.2, FORECASTS, through 3.5, LIABILITIES, and insert in
lieu thereof, the following:

3.2      FORECASTS. McDATA expects to purchase the estimated quantities outlined
in Exhibit A to this Agreement. Concurrent with the signing of this Agreement,
as modified herein, McDATA shall provide SCI with a forecast of Products,
specified by McDATA assembly number, for the [*] period. Such forecast will be
updated [*], and ensure that the forecast period for each assembly is
commensurate with the maximum lead time for each respective assembly, which will
change from time to time. In no event will the forecast period be less than [*].
Except for those quantities for the next [*], which normally would coincide with
quantities for which McDATA has issued Purchase Order(s), such forecast shall be
considered non-binding unless non-cancelable, non-returnable items are procured
as directed by McDATA.

3.3      PURCHASE ORDER. McDATA shall provide Purchase Orders for [*] of
forecast. SCI shall utilize and act upon McDATA's forecast for the upcoming [*]
in the same manner and with the same liability between the parties in the event
there are any administrative delays in the issuance of Purchase Orders for this
time period. All Purchase Orders shall state the item number, quantity ordered,
unit of measure, McDATA assembly number, revision level, description of item,
unit and extended price, delivery dates, method of shipment, and tax status of
each shipment to a location. SCI shall acknowledge receipt and acceptance /
rejection of all Purchase Orders within [*]. No term or condition on SCI's
standard quotation (notwithstanding pricing

assumptions or clarifications thereto) or McDATA's standard purchase order will
modify this Agreement.

3.4      ADDS, RESCHEDULES AND CANCELLATIONS. SCI agrees to provide for
resources sufficient to permit increases up to [*] of Forecast / Purchase Order
quantity of Products which fall within [*] from delivery date, beginning [*]
after first delivery of a newly introduced assembly using SCI purchased
components. McDATA may place such Purchase Orders for delivery of the additional
quantities between [*] from order date. McDATA must approve, in writing, any
expedite charges, non-AVL parts substitutions, or any other cost variances to
current quote.

McDATA may defer scheduled deliveries for a given time period prior to delivery
in accordance with the following schedule:

<TABLE>
<CAPTION>

 Weeks from         Deferral Allowed
  Delivery            (One-Time)                    Comments
 ----------         ----------------                ---------
<S>                      <C>            <C>
  0 - 4 Wks              [*]            Exceptions Only as Mutually Agreed Upon
  4 - 8 Wks              [*]            Multiple Pushes Only as Mutually
 >8 - 12 Wks             [*]            Multiple Pushes Only as Mutually
>12 Weeks                [*]            Multiple Pushes Only as Mutually Agreed Upon

</TABLE>

SCI will plan capacity to service McDATA's forecast requirements. SCI requires
adequate notification time to reallocate resources in the event of cancellations
in order to avoid charges that would otherwise result due to idle resources.
McDATA may therefore cancel quantities forecasted, subject to excess liabilities
described in 3.5 below, in accordance with the following schedule:

>12 Weeks                  [*]            Exceptions Only as Mutually Agreed Upon

</TABLE>

3.5      LIABILITIES. McDATA agrees to assume liability for materials ordered to
forecast which have manufacturer's lead times beyond open Purchase Orders,
provided SCI makes reasonable efforts to cancel, return, restock or otherwise
reallocate obsolete materials. McDATA assumes liability for any Minimum Order
Quantity ("MOQ") specified by McDATA beyond ordinary standard manufacturer MOQ
(e.g., "tape and-reel"), in an effort to reduce part cost. McDATA's

<PAGE>   21

total liability shall normally be five percent (5%) above the cost of materials
remaining in SCI's inventory, unique to McDATA's Products or the result of MOQs,
which SCI is either committed to purchase or is on-hand and are non-returnable
or non-cancelable. As an incentive to expedite the issuance of a Purchase Order
from McDATA to SCI, the five percent (5%) markup shall be reduced to three
percent (3%) in the event McDATA provides a Purchase Order that authorizes SCI
to immediately ship and invoice the total amount of McDATA's obligation,
including (3%) markup, no later than 10 working days from the date the final
excess list is provided to McDATA. SCI shall provide a material exposure report
when requested by McDATA, but no more frequently than weekly, to allow McDATA to
monitor material liability.

Second: Delete Paragraph 4.2, PRICE ADJUSTMENTS, and insert in lieu thereof, the
following:

4.2      PRICE ADJUSTMENTS. The prices for Products listed in Exhibit A shall be
reviewed by SCI and McDATA [*] and updated for [*]. As part of this review, SCI
will roll standards to reflect current market conditions and provide McDATA with
detailed costed BOMs. SCI shall make every effort to provide McDATA with
continuous reductions in Total Cost, and McDATA shall cooperate to the maximum
extent possible to achieve these reductions. Such repricing activities will be
subject to the following terms, effective upon execution of this agreement:

         4.2.1    Regarding the DVP Port and Laser Assemblies (P/Ns
470-00341-400 and 470-000337-500). SCI shall pass through the [*] associated
with the transceivers, part numbers 803-000010-003 and 803-000029-000. The
prices negotiated for the two aforementioned assemblies, less the transceiver
baseline cost of [*] ($[*]/each) and $[*] ($[*]/each), respectively, shall be
[*] by future price decreases (or increases) of ONLY the transceivers. Cypress
(715-000372-000 and 715-000373-000) [*], to the extent negotiated by McDATA in
support of the aforementioned assemblies, shall be [*] in [*].

         4.2.2    Notwithstanding the unique circumstances identified in 4.2.1
above, SCI shall retain all SCI caused price reductions for a period of [*] from
the date such reductions are realized by SCI, after which time such reductions
will be passed on to McDATA in their entirety. Such reductions offered will be
[*] (hereafter referred to as "[*]") of [*] (excluding any [*] separately
authorized by McDATA) that are realized during the same time period.

         4.2.3    Net cost reductions achieved solely due to McDATA's cost
reduction efforts shall be passed on to McDATA in their entirety and made
effective at an appropriate cut-in time.

         4.2.4    Net cost reductions achieved due to SCI and McDATA's combined
cost reduction efforts shall be shared ([*]) with McDATA for a period of [*]
from an appropriate cut-in time, after which time shall be passed on to McDATA
in their entirety.

         4.2.5    Prices quoted, and Purchase Orders issued thereunder, shall
include the discounted purchase prices in support of the [*] payment terms and
described in paragraph 5.3 hereto.

<PAGE>   22
         4.2.6    Prices for assemblies are exclusive of No Trouble Found (NTF)
warranty returns. As such, McDATA and SCI have agreed that, to the extent that
SCI's NTFs, exclusive of McDATA's allowable "lot rejects", exceed the number of
McDATA's pre-HASS test failures that are subsequently verified by SCI McDATA
agrees to pay SCI for on a monthly basis. SCI shall keep records by serial
number relative to the NTFs, and McDATA shall keep records by serial number
relative to test failures on SCI assemblies that were verified by SCI. The net
NTFs over-and-above the McDATA documented and SCI verified test failures shall
be invoiced to McDATA at a mutually agreed upon "NTF" rate for each assembly in
question. McDATA's objective is to jointly verify and virtually eliminate the
occurrence of this type of NTF.

         4.2.7    Component price increases that are unavoidable by SCI / McDATA
shall be [*] to the extent that they are not offset by any reductions in
accordance with 4.2.2 above. These component price increases must be approved by
McDATA prior to component purchase. Such approvals will be jointly expedited as
necessary to support McDATA schedules.

Third:  Add Paragraph 4.4,  TIME & MATERIAL AUTHORIZATIONS, as follows:

4.4      TIME AND MATERIAL AUTHORIZATIONS. McDATA shall have the option, in the
event a nonwarranty repair action is requested, to authorize SCI to proceed with
debug, repair and retest as necessary to repair an assembly being manufactured,
or will be manufactured, at SCI. Such authorization shall be based on (a) labor
incurred for repair and test, at the initial rate of $[*] per hour, including
fractions thereof, and (b) material reimbursement at the current standard cost.

Fourth: Add Paragraph 8.4, LOT REJECTION CRITERIA, and 8.5, PARTS RECLAMATION,
as follows:

8.4      LOT REJECTION CRITERIA. McDATA shall inspect lots delivered by SCI and,
using generally accepted criteria and lot sampling plans (such as C=0,
MIL-STD-105), reject lots delivered by SCI based on said sampling plans,
provided that a "lot" (a) shall not exceed [*] of SCI product deliveries on all
but the DVP Port Assembly, and (b) shall not exceed [*] of SCI product
deliveries for the DVP Port Assembly. This provision was part of SCI's price
reduction strategy to (a) provide early identification of potential process
problems to the mutual benefit of both SCI and McDATA, and (b) reduce the SCI
cost associated with processing and sorting assembly returns in extended,
consolidated lots.

8.5      PARTS RECLAMATION. Undamaged "A" parts can be re-used if assemblies are
scrapped, provided: (1) the "A" parts targeted for reclamation are not the
reason for the scrap, (2) the removal / reuse can be performed to industry
standards, and (3) McDATA provides written approval, which shall not be
unreasonably withheld.

Fifth: Under Paragraph 9.1. PRODUCT WARRANTY, replace the words "[*] from the
date of delivery" with the words "[*] from the date of delivery". Insert after
the first sentence, the sentence "The material warranty provided hereunder shall
in no event exceed the warranty provided by the manufacturer in view of all
environmental stress screening required by

<PAGE>   23
McDATA." Add the sentence, "HASS failures, such as temperature, that cannot be
duplicated by SCI at ambient conditions using SCI test equipment shall be
McDATA's responsibility."

Sixth: Delete the obsolete SCI address and facsimile number from Paragraph 16.5,
NOTICES, and insert in lieu thereof, the following:

                           Facsimile # (719) 380-5888

Seventh: Replace Exhibit A, PRODUCTS AND INITIAL PRICING, with Revision 1 to
Exhibit A, Product Volumes and Pricing, dated 01 May 1996, in its entirety. Note
that the "Director" pricing listed shall be effective concurrent with the first
delivery of Turnkey (i.e., SCI acquired material) DVP Assemblies by SCI, since
the discounted prices assume concurrent material purchase by SCI.

Eighth:  Add Section 18, JUST-IN-TIME SCHEDULING, as follows:

18.      JUST-IN-TIME (JIT) SCHEDULING.

McDATA agrees to assist SCI as necessary to achieve JIT delivery of the DVP Port
Assembly and DVP Laser Assembly's LED and Laser Transceivers. This was an
integral part of SCI's price reduction strategy, and will include SCI/McDATA
joint efforts on other "A" parts as mutually agreed upon.

Ninth: SCI agrees, as part of the consideration for transferring the DVP Port
Assembly to SCI, to absorb the Non-Recurring Engineering (NRE) costs associated
with the DVP assembly for the initial transition only. Subsequent changes or
revisions and updates will be handled as normal, and McDATA agrees to pay for
the NRE costs for the DVP Laser Assembly as quoted by SCI.

Tenth:  Add Section 19,  DVP TRANSITION PLAN, as follows:

19.      DVP TRANSITION PLAN

19.1     OVERLAPPING PRODUCTION. McDATA agrees to pursue overlapping production
from both the current source and SCI for at least thirteen (13) weeks from the
first deliveries made by SCI, to allow adequate time to realize full production
rate and quality efficiencies.

<PAGE>   24
19.2     MATERIAL RISK MITIGATION. SCI agrees to plan material availability at
two weeks prior to the requisite kit release date as defined in 19.3 below. As
part of this strategy, SCI will advise McDATA of those long lead materials and
quantities thereof that must be obtained from the existing source in order to
meet the prescribed McDATA transition schedule. McDATA will ensure such material
acquisitions (via SCI Purchase from McDATA or PO-for-PO replacement and
assumption of orders) are accomplished at or below the SCI quoted standards,
when reviewed in the aggregate. If this is not feasible, McDATA agrees to
promptly reimburse SCI for such variances at their actual cost, or to amortize
such variances into the Assembly unit prices, inclusive of all mark-ups, as
mutually agreed between SCI and McDATA. In addition, SCI will utilize all
resources, including searches of other SCI plants, if shortages are identified
by McDATA that may endanger the scheduled transition. Should acquisitions be
required above the standard cost proposed by SCI as a result of inside lead time
requirements, such Purchase Price Variances (PPVs) shall be submitted to, and
promptly approved or rejected by, McDATA. SCI and McDATA will investigate
alternatives to PPVs rejected by McDATA.

19.3     PRODUCTION RISK MITIGATION. Upon issuance of a Purchase Order to SCI
for the Port Assemblies, McDATA shall within 10 working days thereafter meet
with SCI at a mutually acceptable time and place to disclose all relevant
non-proprietary manufacturing process control data, test data or other
reliability or failure related data that may be useful in avoiding start up
problems on known areas of difficulty. SCI agrees to initially use an extended
three (3) week cycle time until such time SCI is satisfied that the production
rate and quality are sufficient to support McDATA's scheduled deliveries,
exclusive of any verified warranty returns thereunder. SCI will make every
effort to ensure that a substantial portion of the required assembly production
is completed within the first ten (10) days of cycle time. Process problems
related to the manufacture and test of the port assemblies shall be identified
to McDATA upon discovery to ensure McDATA involvement and transfer of knowledge
relative to prior manufacturing problems and difficulties historically
encountered by the previous manufacturer. SCI agrees to work with McDATA to ramp
the production volumes up to the desired run rate over a thirteen (13) week
period, barring no unforeseen material availability problems.

19.4     TEST DEVELOPMENT AND RISK MITIGATION. McDATA shall participate and
cooperate with SCI to rapidly develop and fabricate test fixtures and programs
suitable for the DVP assemblies. Such cooperation shall prioritize technical
information needs by SCI to prevent negative impacts to the transition schedule
as established with McDATA. SCI will ensure that established test development
schedules are managed and maintained, including any subcontracted assistance and
purchased fixtures.

19.5     ESS THERMAL CHAMBER. SCI has identified an 18 week lead time for an
ESPEC oven that would be completely compatible with SCI's existing chamber.
Inasmuch as this lead time does not support McDATA's desired transition
schedule, SCI and McDATA will work together to ensure that a work around plan is
established for an interim solution for ESS testing.

19.6     NON-WARRANTY SUPPORT. SCI agrees to support McDATA's potential need for
repair or upgrade of predecessor assemblies during or after the transition
period on a Non-Warranty, Time

<PAGE>   25
and Materials basis as mutually scheduled. Such support will be provided on a
non-interference basis to McDATA's Production assemblies at SCI, unless
otherwise directed by McDATA.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement in duplicate
by their duly authorized representatives.

                                  ADDENDUM #2
                      MANUFACTURING AGREEMENT #01-92-03-0A
 BETWEEN MCDATA CORPORATION AND SCI TECHNOLOGY, INC., D.B.A. SCI SYSTEMS, INC.

                                 30 APRIL 1998

This Addendum is entered into by McDATA Corporation ("McDATA"), having its
principal place of business located at 310 Interlocken Parkway, Broomfield,
Colorado, 80021-3464, and SCI Technology, Inc. ("SCI"), 5525 Astrozon Blvd.,
Colorado Springs, Colorado 80916-4226.

WHEREAS, McDATA and SCI have entered into Manufacturing Agreement 01-92-03-0A
executed in full and effective 16 June 1992, as amended on 23 May 1996 via
Addendum thereto;

WHEREAS, McDATA and SCI have mutually agreed to enter into additional
agreements and alterations to this agreement as part of further refinement of
the business relationship;

WHEREAS, McDATA and SCI have agreed to restate certain portions of said
agreement for clarity;

WHEREAS, McDATA and SCI agree that the provisions of this Addendum will take
precedence over the original agreement and addendum thereto in the event of a
conflict;

NOW THEREFORE, the aforementioned agreement is amended and the parties hereto
agree as follows:

FIRST:  Add Item 20, Creation of Component Inventory Buffers, as follows:

20.0  CREATION OF COMPONENT INVENTORY BUFFERS.

McDATA may identify critical components for which buffer inventory quantities
will need to be established and/or maintained. This will be accomplished using
mutually written agreed upon approaches which may include, but not be limited
to, any or all the following approaches: Independent MRP demand with
corresponding McDATA P.O. coverage, increased shrinkage percentages, and
increased wait days. Consideration for the carrying costs of these components
shall be included in the current product pricing as identified in SCI
quotations and corresponding McDATA purchase orders.

McDATA agrees to be liable for the additional risk associated with the above
inventory buffers, including but not limited to parts obsolescence,
cancellation inventory costs, delays in realization of market price
fluctuations (up or down), and potential carrying costs in the event of
schedule pushes.

Such inventory liabilities are further defined in the existing agreement and
addendum thereto.

SECOND:  Delete Paragraphs 4.2.2 through 4.2.4, under Price Adjustments, and
insert in lieu thereof, the following:

     4.2.2  Notwithstanding the unique circumstances identified in 4.2.1 above,
SCI and McDATA shall equally [*] share all SCI caused price reductions. The
residual SCI retained price reductions shall normally rollover to the next
quarter's price reduction activities, except that all SCI retained price
reductions will be zeroed out and passed on to McDATA with the pricing provided
for the first calendar quarter of each year (Jan., Feb. and Mar.). Quarterly
reductions offered will be net (hereafter referred to as "net cost reductions")
of any increases in standard costs (excluding any expedite costs separately
authorized by McDATA) that are realized during the same time period.

     4.2.3  Net cost reductions achieved solely due to McDATA's cost reduction
efforts shall be passed on to McDATA in their entirety and made effective at an
appropriate cut-in time.

     4.2.4  Net cost reductions achieved due to SCI and McDATA's combined cost
reduction efforts shall be shared [*] in the same manner as Paragraph 4.2.2
above.

<PAGE>   28

THIRD:  Replace Paragraph 4.4, TIME & MATERIAL AUTHORIZATIONS, as follows to
recognize current rates in effect at SCI:

4.4  TIME AND MATERIAL AUTHORIZATIONS.

McDATA shall have the option, in the event a non-warranty repair action is
requested, to authorize SCI to proceed with up-level, rework, debug, repair
and/or retest as necessary to an assembly which may or may not have been built
by SCI. Such authorization shall be based on (a) labor incurred for repair and
test, at the current rate of [*] including fractions thereof, and (b) material
reimbursement at the current standard cost.

FOURTH:  Add Section 21, ADMINISTRATION OF HASS FAILURES, as follows:

21.0 ADMINISTRATION OF HASS FAILURES.

SCI has agreed to perform additional debug and troubleshoot on HASS related
failures that were previously serviced by McDATA or returned to SCI. SCI and
McDATA have agreed to the cost associated with such support, based on a planned
level of effort of two (2) full time technicians. Such costs and failure
analysis activity will be reviewed by McDATA and SCI as part of the quarterly
price reviews with the necessary adjustments to assure that the agreed upon
costs are fairly administered and SCI is meeting its RMA turnaround goals. If
SCI does not meet its goals for 2 consecutive months, SCI agrees to negotiate
appropriate forfeiture of up to 100% of the agreed upon costs of these two (2)
technicians until the target is met.

Performance against the initial RMA turnaround goals listed below shall be
separately measured and reported monthly. Data provided monthly shall be
Average Age for all RMA assets that have been at SCI longer than 2 weeks, and
the number of delinquent (age exceeds goal) RMA assemblies outstanding in each
category below.

     21.1 Two  (2) weeks for receiving inspection rejections,
     21.2 Four (4) weeks for all in-process rejections, and
     21.3 Six  (6) weeks for HASS related failures.

SCI & McDATA must agree on specific closure plans for HASS related failures
that are not closed within 30 days. Unusual circumstances (unusual quantities
or technical issues) may result in alternate target schedules as mutually
agreed upon. Should McDATA and SCI find that the volumes being returned due to
HASS related failures exceed the reasonable capacity of the two technicians,
alternate arrangements shall be made and pricing associated therewith
negotiated separately.

FIFTH:  This addendum extends the terms and conditions of the original
Manufacturing Agreement, as modified by all subsequent addendums, including
this one, for a period of one year as allowed under section 2 of the agreement,
through 31 December 1998. This agreement will automatically renew in thirty (30)
day increments if obligations continue to be made beyond the existing term, and
if neither party notifies the other of intentions to cancel or renegotiate such
agreement at least sixty (60) days prior to the expiration date.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement in
duplicate by their duly authorized representatives.
