     The  term  Holder  shall refer to the original Holder and upon transfer, to

any  judgment  obtained  by  Holder.

     Maker shall have the option to prepay this Note, in full or in part, at any
time  without  penalty.

     Failure  of  Holder to exercise any option hereunder shall not constitute a

performance.

                                PAYMENT AGREEMENT

All  patties  acknowledge  that  YP.Net,  Inc.  (Formerly know as RIGL) could be
declared  in default if Mathew & Markson LTD. ("M&M") exercised its rights under
the Modification Agreement dated September 03, 1999 between the parties. YP.Net,
Inc.  has  made  no payments pursuant to either agreement of either principal or
interest  since  the September, 1999 payment. M&M has not and is not waiving any
of  its  rights  under  the  September  03,  1999  agreement.

In  order  to induce M&M to enter into negotiations with YP.Net, Inc. to either;
continue  to  delay the declaration of default or to further extend the time for
payment,  YP.Net,  Inc. will tender to M&M the sum of $50,000.00 as a good faith
fee.  M&M  will credit this sum to the outstanding interest due M&M from YP.Net,
Inc.

In  addition,  YP.Net,  Inc  will  continue  to make weekly payments to M&M on a
weekly  basis  until advised otherwise by M&M.  YP.Net, inc.  will be allowed to
pay  its  minimum  obligations  to the Van Sickles first and then Finova Capital
Corp.  under the terms of the agreements between the patties.  Then YP.Net, Inc.
will  maintain  a  cash  reserve  or  availability under its loan agreement with
Finova  sufficient  to  fund  2  weeks  worth  of expenses.  All regular monthly
budgetary  expenses will then be paid.  The balance will then be paid to M&M.  A
representative  of  M&M  will  have  the  final authority to approve all regular
monthly budgetary expenses until M&M is paid in full or more formal arrangements
are  agreed  to  between the parties.  It is understood between the parties that
M&M's  willingness to accept this good faith payment and or weekly payments does
not in any way limit M&M's rights to declare a default or the ability to enforce
strict  compliance  with the tennis and conditions of the original agreement and
the  modification  agreement  dated  September  03,  1999.

The  parties understand that this payment agreement is a temporary agreement and
does  not in anyway modify any agreements between M&M and YP.Net, Inc., nor does
it  change any obligations of YP.Net, inc. to M&M. YP.Net, Inc. is encouraged to
find alternative sources of capital to pay off its obligation herein with prompt
dispatch.  It  is  agreed  between  M&M  and  YP.Net,  Inc  as  herein  above:

YP.NET,  Inc.
