                        CNT REPORTS FIRST QUARTER RESULTS

                 SIGNIFICANTLY IMPROVED RESULTS VS. PRIOR YEAR;
                  ACQUISITION OF INRANGE TECHNOLOGIES COMPLETED

MINNEAPOLIS, MAY 12, 2003 -- CNT (Nasdaq: CMNT), the global expert in storage
networking solutions, today reported financial results for the fiscal first
quarter ended April 30, 2003. Revenue totaled $52.3 million, a 16 percent
increase from $45.2 million in the first quarter of 2002. Included in the fiscal
2003 first quarter is approximately $4.9 million of revenue generated from the
June 2002 acquisition of BI-Tech Solutions.

On the basis of generally accepted accounting principles (GAAP), the company
reported a net loss of $2.1 million, or $.08 per share, compared to a net loss
of $13.8 million, or $.45 per share, in the year-ago quarter. On a pro forma
basis, the company reported a net loss of $700,000, or $.03 per share, compared
to a net loss of $3.7 million, or $.12 per share, in the prior-year period. Pro
forma results for the fiscal 2003 first quarter exclude a $312,000 earn-out
payable to the BI-Tech employees, and include income taxes at a 34% effective
rate. Pro forma results for the fiscal 2002 first quarter exclude a $10.1
million cumulative effect of change in accounting principle for the write-down
of goodwill associated with the adoption of SFAS No. 142 "Goodwill and Other
Intangible Assets." A reconciliation of reported and pro forma results is
included in the attached financial statements.

Third-party product revenues for the fiscal 2003 first quarter were $16.1
million, up $8.6 million or 115 percent from the prior year period. Consulting
fee revenues increased to $7.1 million, up 57% from $4.5 million in the fiscal
2002 first quarter.

CNT product revenues were $18.3 million for the fiscal first quarter, down $4.0
million or 18 percent from the first quarter last year. Maintenance revenues
decreased slightly to $10.8 million in the fiscal first quarter from $10.9
million last year.

"On May 5, 2003, we completed our strategic acquisition of Inrange Technologies
for $190 million in cash. The acquisition makes CNT/Inrange one of the world's
largest providers of complete storage networking products, solutions and
services, with combined 2002 pro forma annual GAAP revenues of $435 million,
global leadership positions in our markets and operations worldwide," said Tom
Hudson, CNT's chairman, president and chief executive officer. "The acquisition
significantly broadens and strengthens our portfolio of storage networking
products and solutions, increases our global size and scope, expands our
customer base and provides us with significant scale and cost reduction
opportunities. Inrange's Fibre Channel director switches, storage networking
products and wave division multiplexing products are a strong fit with CNT's
storage networking solutions offerings, which include wide area network
products, consulting, design, implementation, third party storage product
integration and network monitoring services."

"Our combined company will be a global leader in SAN services, with a recurring
maintenance revenue stream of nearly $90 million and a $60 million consulting
and professional services division, one of the largest in the industry dedicated
to storage networking," Hudson added. "Together we have more than 4,000 customer
establishments world-wide, including many of the Fortune 500 corporations and
Global 1000 businesses in the United States, Canada, United Kingdom, France,
Germany, Italy, Switzerland, China, Japan and Australia. With our combined
product offerings and extensive suite of service offerings, we are in a unique
position to partner with enterprise customers to implement and manage their
complex, large scale, multi-vendor storage networking solutions."

"Our senior management team is preparing a detailed integration plan and will
work to realize substantial revenue and cost synergies at the combined company,
including eliminating duplicative costs for personnel and facilities,
integrating product and service offerings, achieving operating efficiencies, and
enhancing productivity," Hudson continued. "We anticipate that the integration
of all functional disciplines, geographies and business systems will be complete
by the end of our second fiscal quarter ending July 31, 2003. The integration of
product and service offerings and manufacturing operations will be substantially
underway by this time."

"We anticipate the acquisition will be accretive to earnings per share by at
least 10 percent in 2003, and to achieve annual cost savings of between $10 and
$15 million to be fully phased in by early 2004," commented Greg Barnum, CNT's
chief financial officer. "We are committed to retaining the best employees from
our combined companies and to creating the most efficient organization possible.
We expect to record an integration charge in our fiscal second quarter ending
July 31, 2003 for

severance costs related to termination of CNT employees, professional fees and
travel costs related to the integration. Other possible integration charges
include inventory and asset write-downs related to discontinued product lines.
We may also record a charge for in-process research and development pending
completion of the purchase price allocation analysis. The size and scope of any
charges will not be known until our integration planning is complete."

CNT ended the quarter with a strong balance sheet and positive cash flow. Cash
and investments were up $12 million to $221 million. Cash flow from operations
was a positive $13.9 million, including a $10.4 million reduction in
receivables, due in part to improved DSO and collections, and a $6.2 million
reduction in inventory due to better inventory turns and management. The
combined CNT/Inrange has about $70 million of cash on-hand, prior to payment of
transaction fees and integration costs.

OUTLOOK

We are planning our integration and re-sizing of the combined CNT/Inrange
organization. Due to the early stage of the integration, we will not be
publishing guidance at this time. We expect to have an accurate estimate of
revenue and profitability prior to the start of our fiscal third quarter.
