                                PROMISSORY NOTE


$40,000 in Principal                                          September 19, 2000


         FOR VALUE RECEIVED, CityXpress.com Corp., a Florida corporation
("Borrower"), promises to pay to the order of Lee Enterprises, Incorporated
("Lender"), the principal FORTY THOUSAND DOLLARS ($40,000) advanced to Borrower
pursuant to Section 2.1 of the Loan and General Security Agreement by and among
Borrower, Welcome To Search Engine Inc., a private British Columbia, Canada
company, and Xceedx Technologies Inc., a private British Columbia, Canada
company, and Lender, dated August 17, 2000 (the "Loan Agreement") in lawful
money of the United States 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 such address at the "Prime Rate" of interest announced in The Wall
Street Journal from time to time (the "Wall Street Journal Prime Rate"). The
principal sum of and the accrued but unpaid interest on this Note shall become
due and payable upon the occurrence of an Event of Default, for purposes of
this Agreement as defined in the Loan Agreement, and such principal sum shall
otherwise become due and payable December 19, 2000, unless Lender, in its sole
discretion, notifies Borrower in writing that this Note shall be converted into
a Demand Note, in which event the principal sum of and the accrued but unpaid
interest on this Note shall otherwise become due and payable upon demand of the
Lender.

         Payment shall be made by Borrower to Lender at 400 Putnam Building,
215 North Main Street, Davenport, Iowa 52801-1924 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.

         Upon an Event of Default, the holder hereof may, at its option,
declare the entire unpaid principal of an accrued interest on this Note
immediately due and payable, without demand or presentment, both of which are
hereby waived, and the holder hereof shall have the right to foreclosure or
otherwise enforce all liens or security interests securing payment hereof. In
addition, to the extent permitted by law, upon the occurrence of an Event of
Default, the rate of interest applicable to this Note shall increase from the
Wall Street Journal Prime Rate to 5% over the Wall Street Journal Prime Rate
until such Event of Default shall be cured.

this Note, and hereby consent to any and all such.

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
