Subject: Contract Renewal

Mark; please use this letter as notification of our intent to extend the
existing Agreement with Brocade for another year. Outlined below is the unit
pricing that was agreed to last week in a teleconference between Pat Jackson,
Charlie Smith, Doug Fierro, Ron Koshko and myself.

Also, for contract file purposes, I wanted to make sure I included in this
letter that Brocade agreed to supply EMC with Extended Fabric License keys [*]
to use for Customer Service Field Spare replacement.

If you have any questions or issues with the pricing or renewal please give me a
call.

Q1 2001 pricing agreement:

EMC part number       Brocade part number          Agreed to Q1,'00 unit price
