(1)    Pursuant to Staff Accounting Bulletin Number 83, for proper calculation
       of the three and nine months ended September 30, 1996 weighted average
       common shares outstanding, stock options granted and stock issued within
       one year prior to Primus's November 7, 1996 initial public offering have
       been treated as outstanding for all of 1996 using the treasury stock
       method. In the three and nine months ended September 30, 1997, the
       weighted average common shares outstanding has been calculated under
       Accounting Principles Board (APB) Statement No. 15.
