Attention:  Mr. Errol Gerson, Chief Executive Officer

     Re:  Agreement between i3 Mobile. Inc. and iNetNow, Inc., dated as of
          October 1, 2001

Gentlemen:

Reference is made to that certain Agreement, dated as of October 1, 2001, (the
"Agreement") between iNetNow, Inc. ("iNetNow") and 13 Mobile, Inc. ("i3"), as
amended on November 7, 2001 (the "Amendment"). This letter sets forth the
agreement between iNetNow and i3 with respect to the subject matter thereof, and
shall supersede any aspect of the Agreement and/or the Amendment contrary to or
inconsistent with the terms regarding the subject matter hereof. Capitalized
terms used but not otherwise defined herein shall have the meanings set forth in
the Agreement and the Amendment.

1.   Indebtedness. (a) Upon satisfactory completion (as determined by i3 in its
sole discretion) of the matters set forth in Sections 2-4 below, 13 shall
irrevocably forgive any and all debts and obligations in excess of $675,600.00
outstanding as of January 15, 2002 (including interest expenses) pursuant to
Section 1.7 of the Agreement (as amended) and that certain Senior Secured
Promissory Note, dated October 17, 2001, of iNetNow in favor of i3.

     (b) The last three sentences of Section 1.8 of the Agreement (as amended)
are hereby deleted in their entirety and replaced with the following:

         "In the event that the Fee for any month is less than the Expense
     Payment for such month, then the following calculations shall apply to
     determine the amount of the additional advance for such month
     (collectively, "Incremental Debt") under the Senior Secured Promissory
     Note, dated October 17, 2001, between iNetNow and i3, and shall increase
     the outstanding indebtedness of iNetNow to i3 thereunder: (i) if the excess
     of Expense Payment for such month over the Fee for such month ("Monthly
     Excess") is less than the Expense Payment less any amounts attributable to
     salary and benefits for i3Mobile-Dedicated Personnel ("Non-Payroll
     Expenses") then the Incremental Debt for that month shall be equal to the
     Monthly Excess; and (ii) if the Monthly Excess is greater than the
     Non-Payroll Expenses then the Incremental Debt for that month shall be
     equal to the Non-Payroll Expenses. In the event that the Fee for any month
     is greater than the Expense Payment for such month, then, in lieu of i3
     paying such Fee, there shall be credited against the $675,600.00, plus
     Incremental Debt and accrued interest, owed to i3 as of January 15, 2002,
     as partial repayment thereof, the amount by which such Fee exceeds such
     Expense Payment. Such crediting and partial repayment shall continue until
     such $675,600.00, plus any Incremental Debt and accrued interest, has been
     fully repaid, and thereafter i3 shall pay to iNetNow the monthly Fee in
     cash to the extent in excess of such monthly Expense Payment."
