Directors, commented, "although the financial results for the second quarter are
disappointing, we are pleased with the progress we have made in gaining customer
acceptance of our Storage Area Network Solutions as well as the integration of
the nStor Technologies, Inc. ("nStor") product line.

"Andataco has been advised that nStor completed its purchase of W. David Sykes'
block of shares in Andataco, (representing 75.7% of the outstanding common stock
of Andataco, Inc.) and the note in the principal amount of $5,196,000 owed by
Andataco, Inc. to Mr. Sykes, as of June 8, 1999 and that nStor has stated that
it intends to acquire the remaining outstanding shares of Andataco, for an
amount to be determined by an independent valuation of the Andataco shares, in a
transaction which should be completed by September 30, 1999. In conjunction with
the change in control the existing members of the board of directors have
indicated an intention to tender their resignation. The Company is in the
process of working out an orderly transition of the board of directors which is
expected prior to month's end.

"Steps are underway to affect the integration of the nStor product line with the
Andataco product line which will allow us to offer a complete line of storage
solutions to our customers."
