                        SETTLEMENT AND LICENSE AGREEMENT

This Settlement and License Agreement (the "Agreement") sets forth the terms
upon which Crossroads Systems, Inc., a Texas Corporation ("Crossroads") and
Advanced Digital Information Corporation, a Washington corporation, and its
majority owned subsidiaries including Pathlight Technology, Inc. ("Pathlight"),
a Delaware corporation and a wholly-owned subsidiary of Advanced Digital
Information Corporation (collectively, "ADIC"), agree to settle the litigation
currently pending before the U.S. District Court of the Western District of
Texas, Austin Division, captioned Crossroads Systems, (Texas), Inc. vs.
Pathlight Technology, Inc. Civil Action No. A-00CA-248-SS (the "Patent
Litigation"). This Agreement shall be effective as of the last execution date
set forth below (the "Effective Date").

                                   BACKGROUND

Crossroads is the owner of all right, title and interest in and to the `972
Patent. On or about April 10, 1999, Crossroads filed a complaint in the Patent
Litigation alleging the Accused Products infringe the `972 Patent and demanding
judgment against Pathlight for such infringement. During the Patent Litigation,
Advanced Digital Information Corporation acquired Pathlight. It is now the
desire and intention of Crossroads and ADIC to settle and resolve all disputes,
differences and claims which exist in the Patent Litigation. To that end,
Crossroads grants ADIC a license under the `972 Patent to develop, manufacture,
use, and sell Licensed Product(s) in exchange for a lump sum payment from ADIC
and acknowledgement by ADIC of both the validity of the `972 Patent and
infringement of the `972 Patent by the Accused Products.

In consideration of the mutual promises contained herein, and other good and
valuable consideration, the adequacy of which is hereby acknowledged, the
parties hereto agree as follows:

         15.      RELATIONSHIP OF PARTIES

         17.      CONSTRUCTION

         The language of this Agreement shall be construed as a whole according

         The parties acknowledge and agree that the lump sum payment (the
         Pre-paid Royalties and Past Damages Payment) shall not be used by
         either party against the other in any future litigation or arbitration
         for the purpose of establishing a "reasonable royalty" rate.
         Notwithstanding the foregoing, and unless Crossroads provides contrary
         instructions, the parties agree that vis-a-vis third parties, the lump
         sum payment (the Pre-paid Royalties Past Damages Payment) shall be
         considered a reasonable royalty rate for a license of the `972 Patent.
