potential benefits of this Option, the maximum aggregate number and kind of
shares or securities of the Company subject to this Option, and the Strike Price

corporation, or the sale or exchange of all or substantially all of the assets
of the Company, or a reorganization or liquidation of the Company, the Optionee
shall be entitled to receive upon exercise and payment in accordance with the
terms of the Option the same shares, securities or property as he or she would
have been entitled to receive upon the occurrence of such event if he or she had
been, immediately prior to such event, the owner of the number of Option Shares.
In lieu of the foregoing, however, the Board may upon written notice to the
Optionee provide that, unless theretofore exercised, this Option shall expire as
of the earlier of the Expiration Date or the date specified in such notice which
may not be less than 20 days after the date of such notice.  In connection with

                  the reason for rejection within [*] after receipt of such
                  purchase order. Unless Reseller is in material breach of this
                  Agreement, McDATA shall be obligated to accept Reseller's

                  governed by the terms and conditions of this Agreement, and
                  none of the terms or conditions of Reseller's purchase order
                  shall be applicable if they are in conflict with the terms or
                  conditions of this Agreement.

                  after receipt of Reseller's purchase order (ARO) for
                  forecasted quantities of Products. If Reseller requires
                  quantities in excess of the forecast or shipment lead times
                  less than [*], McDATA will use its reasonable commercial

                  export documentation 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 Reseller of the
                  possibility of a delay and of the revised ship date within [*]
                  of its receipt of such Purchase Change Order such that
                  Reseller can manage the situation with its End User Customer.

                  with the terms set forth in Section 3.2.2 herein.

         11.4     ENGINEERING CHANGES. McDATA reserves the right to make a
                  change to any Products at any time prior to shipment if (a)
                  the change is necessary to make the Products function in
                  accordance with the specifications current at the time of
                  shipment of such Products and/or meet the then-current
                  requirements for operation as published by any of the
                  regulatory agencies listed in the specifications, or (b)
                  subject to Section 11.2, McDATA in good faith determines that
                  such change does not adversely affect End User Customer's use
                  of the Products. McDATA will communicate as expeditiously as
                  possible any changes that adversely affect End User Customer's
                  use. All rights in and to any Product design changes will be
                  the exclusive property of McDATA.

         11.5     FIELD MODIFICATIONS. To the extent that McDATA determines that
                  any Product in the field requires modification as the result
                  of an engineering change, McDATA shall be responsible for such
                  field modification, whether such change is retrofitable in the
                  field or requires returning such Product to McDATA.

         11.6     IMPROVEMENTS. If McDATA makes generally available to its
                  resellers and end user customers any new or improved Product
                  which may include new models of or options or features
                  ("Improved Products"), McDATA agrees to give Reseller the
                  right to purchase and resell such Improved Products pursuant
                  to this Agreement and to have access to such Improved Products
                  including volumes, samples, timing and technical support
                  services at least equal to that provided to any other party.

         11.7     RESELLER MODIFICATION. Reseller represents that in no event
                  shall Reseller alter any Product in any way to modify the
                  performance characteristics of that Product without the prior
                  written permission of McDATA. The appropriate identification
                  labels, regulatory agency marks and verification of FCC Class

                  replace such marks or labels. McDATA hereby disclaims any
                  liability for the possession, use, resale, or operation of any
                  Products which, as a result of an alteration by Reseller or
                  any third party, affects its compliance with the applicable
                  regulations and/or requirements.

         11.8     PRODUCT DISCONTINUANCE. McDATA reserves the right to
                  discontinue Products by notifying Reseller in writing at least
                  ninety (90) days prior to the discontinuance date. McDATA
                  agrees to honor all purchases orders received and accepted by
                  McDATA prior to the date specified on the discontinuance

                  to the foregoing restrictions and have executed a written
                  agreement with Reseller regarding same.

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
     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 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 shall survive
                  termination of this Agreement.

              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;

         connection with the Products are routinely archived and documented;

         the initial installation site to a new location, you agree to notify
         McDATA in writing ninety (90) days prior to the relocation date.

           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
