                 CIBER COMPLETES ACQUISITION OF ARIS CORPORATION

     GREENWOOD VILLAGE, Colo. - Sept. 19, 2001 - CIBER, Inc. (NYSE: CBR) and
Aris Corporation (NASDAQ: ARSC) today announced the successful completion of the
acquisition of Aris by CIBER, effective September 18, 2001.

     "As with virtually all IT services companies, Aris is not as large as it
was last spring, however, the pricing mechanisms of this combination
accommodated the anticipation of this. We have confirmed our belief from June,
when this was preliminarily announced, that we have found very good folks at
Aris' practice/operational level. The combining of corporate offices and
consolidation of certain overhead positions should put these operations on track
to perform profitably at CIBER," said Mac Slingerlend, CIBER's President and
Chief Executive Officer.

     Aris' operations will be split between CIBER Enterprise Solutions, CIBER's
Enterprise Resource Planning (ERP) oriented practices, because of Aris'
concentration on Oracle software in the U.S. and Microsoft software in the
United Kingdom, and CIBER's core branch operations for a portion of Aris'
Seattle and New Jersey operations.

     "This business combination is an excellent fit for our outstanding
employees and world-class customers. Over the last few months, we have continued
to be impressed by the experience of CIBER's management team and we are more
convinced than ever that this is a significant win for Aris and CIBER
shareholders, employees and customers alike," said Paul Song, Aris' Chairman and
Founder.

     Based on terms of the definitive agreement to merge, the purchase price
will be $1.30 cash plus .1937 CIBER shares for each Aris share. Based on the
pricing period established in the merger agreement, this represents $2.45 of
value for each Aris share. The total value of the transaction is approximately
$28 million. Aris' shareholders voted to complete the transaction on September
11, 2001, subject to final closing procedures.

     It is projected that Aris' operations will represent $30 million to $35
million in annual revenue and that the Aris balance sheet as of the closing date
will deliver approximately $28 million in tangible net worth.
