Note (7) Acquisitions and Divestitures

Divestitures, Page 59

1. We note from your disclosures that in December, 2003, Systat
acquired an exclusive worldwide license to distribute your Sigma-
series line of products for a three-year period and purchased
certain
related assets.  In addition you disclose that this transaction
was
accounted for as the divestiture of a business, a gain of
approximately $8.6 million was recorded and goodwill was reduced
by
$1 million to reflect the estimated goodwill allocated to this
business. Tell us how you considered presenting and disclosing
discontinued operations for the divestiture of this business.
Specifically address your consideration of paragraphs 41 -44 of
SFAS
144 in your response. In addition tell us how you considered the
divestiture of this business in your discussion of results of
operations (impact on revenues and expenses) and cash flows in
Managements Discussion and Analysis.
2. If the sale of the Sigma-series line of products does not
qualify
as a discontinued operation tell us how you considered the
provisions
of SOP 97-2 in accounting for this transaction as the sale or
license
of software.

******

	 We urge all persons who are responsible for the accuracy and

proceeding initiated by the Commission or any person under the
federal securities laws of the United States.

      In addition, please be advised that the Division of
