Item 4.  Changes In Registrant's Certifying Accountants

     On November 19, 1999, Cumetrix Data Systems Corp. (the "Company") decided
to replace Arthur Andersen LLP ("Andersen") as its principal accountants and
terminated the relationship. Andersen's report on the Company's financial
statements for each of the last two fiscal years did not contain an adverse
opinion or disclaimer of opinion and was not qualified or modified as to
uncertainty, audit scope or accounting principles. The decision to change
accountants was approved by the Board of Directors. During the Company's two
most recent fiscal years and in the period since March 31, 1999, there were no
disagreements with Andersen on any matter of accounting principles or practices,
financial statement disclosure or auditing scope or procedure which
disagreements, if not resolved to the satisfaction of Andersen, would have
caused it to make reference to the subject matter of the disagreements in
connection with its report. Andersen initially expressed unwillingness to rely
on management's representations with respect to the Company's financial
statements at March 31, 1999, and for the year then ended (the "1999 Annual
Statements"). After the Company responded to issues raised by Andersen (see
Item 7. "Management's Discussion and Analysis of Financial Condition and Results
of Operations - Results of Investigation" in the Company's Annual Report on Form
10--K for the year ended March 31, 1999), Andersen rendered its unqualified
opinion on the 1999 Annual Statements.
