                                PROMISSORY NOTE


$25,000 IN PRINCIPAL                                        AS OF APRIL 20, 2000


         FOR VALUE RECEIVED, CityXpress.com Corp., a Florida corporation
("Borrower"), promises to pay to the order of Phil Dubois ("Lender"), the
principal of TWENTY FIVE THOUSAND DOLLARS ($25,000) advanced to Borrower by and
among Borrower, WelcomeTo Search Engine Inc., a private British Columbia, Canada
company, and Xceedx Technologies Inc., a private British Columbia, Canada
company, and Lender in lawful money of Canada and to pay interest on the unpaid
balance hereof calculated from the date of this Note until such amount is
repaid, in like money at the monthly interest set by the Scotia McLeod monthly
interest rate. The principal sum of $25,000 and the accrued but unpaid interest
on this Note shall become due and payable upon demand of the Lender.

         Payment shall be made by Borrower to Lender at 6832 Linden Avenue
Burnaby BC V5E 3G4 or at such other address as Lender may from time to time
specify in writing to Borrower. Interest shall be computed on a 365/365 simple
interest basis, by applying the ratio of the annual interest rate over the
number of days in a year, multiplied by the actual number of days the principal
balance is outstanding. Unless otherwise agreed or required by applicable law,
payments will be applied first to accrued interest, then to principal, and any
remaining amount to any unpaid collection costs and late charges.

         No delay or omission of the holder to exercise rights under this Note
shall impair any such right or power or shall be construed to be a waiver of
any such default or an acquiescence therein. No waiver of any default shall be
construed, taken or held to be a waiver, acquiescence in or consent to, any
further or succeeding default of the same nature.

         Borrower, and each endorser, and any other party ever liable for
payment of any sums of money payable on this Note, agree that their liability
on this Note shall not be affected by any renewal or extension in the time of
payment hereof, or by any release or change in any security for the payment of
this Note, and hereby consent to any and all such.

         This Note may be prepaid without penalty, in whole or in part, at any
time.

         In the event this Note is placed in the hands of attorneys for
collection, or is collected by suit or through a court of bankruptcy, Borrower
shall pay to the holder hereof court costs and reasonable attorney's fees for
such collection. This Note shall be governed by and construed in accordance
with the laws of the State of Iowa excluding choice-of-law principles of the
law of such state what would require the application of the laws of a
jurisdiction other than such state.
