          If so, attach an explanation of the anticipated change, both

reasonable estimate of the results cannot be made.

The Company reported a loss of $19.6 million on revenues of $22.6 million
for the first quarter ended March 29, 2003.  Included in the loss is a reserve
of $6.9 million for excess and obsolete inventory prompted by changes in the
sales forecast and planned discontinuance of certain Mammoth tape drive and
automation products and a $6.1 million bad debt reserve against debt owed the
company by a major customer that is experiencing financial difficulty.
In the prior quarter the company recorded a loss of $8.1 million on revenues
of $24.0 million.

While revenues declined 6 percent versus the prior quarter, gross profit for
the quarter, net of the inventory reserve, improved 20 percent compared to the
previous quarter due to continued focus by management on reducing overhead
costs.  First quarter operating expenses, net of the bad debt reserve,
declined 9 percent versus the fourth quarter primarily due to management's
efforts to bring spending in line with revenue expectations.

Deliveries from the Company's suppliers slowed considerably during the quarter
because of liquidity constraints and while it was in the process of negotiating
repayment plans with major suppliers.  This limited the Company's ability to
ship product and resulted in lower first quarter revenues compared to last
quarter.

Because of the delay in product shipments from suppliers, the Company paid
higher freight charges due to accelerated shipments at the end of the quarter,
trying to catch up with demand. Also, the Company incurred expenses associated
with the March reduction in force.  These items added together with the
reserves account for a very large part of the operating loss, the remainder
being due to lower revenues.

Changes to the company's balance sheet, including a reduction in accounts
payable from $30.6 million in the fourth quarter to $14.3 million in the
first quarter, and increases in the current portion of long-term liabilities
from $1.8 million to $15.7 million and in long-term liabilities from $3.4
million to $9.1 million over the same period, reflect the effects of the
repayment plans Exabyte negotiated with certain major suppliers.  Changes to
accounts receivable include the effects of the bad debt reserve and improved
collections.  Changes to inventories include the effects of the inventory
reserve and tighter inventory management.
