US$200,000                                                        August 4, 2000

     FOR  VALUE  RECEIVED,  the  undersigned,  Fullcomm  Technologies,  Inc.,  a
Delaware  corporation  (the  "Obligor"),  hereby promises to pay to the order of
Viking  Investment  Group II,  Inc.,  a Delaware  company  (the  "Holder"),  the
principal sum of Two Hundred  Thousand Dollars  ($200,000)  payable as set forth
below.  The Obligor also promises to pay to the order of the Holder  interest on
the  principal  amount  hereof  at a rate per  annum  equal to ten and  one-half
percent  (10.5%),  which interest shall be payable at such time as the principal
is due  hereunder.  Interest shall be calculated on the basis of the year of 365
days and for the number of days  actually  elapsed.  Any amounts of interest and
principal  not paid when due shall bear interest at the maximum rate of interest
allowed by  applicable  law. The payments of  principal  and interest  hereunder
shall be made in coin or currency of the United  States of America  which at the
time of payment  shall be legal  tender  therein  for the  payment of public and
private debts.

     This  Note  shall  be  subject  to  the  following   additional  terms  and
conditions:

     1.   Payments.  Subject to Section 2 hereof, all principal and interest due
          hereunder  shall be in one (1)  installment  on  August  3,  2001 (the
          "Maturity  Date").  In the event that any payment to be made hereunder
          shall be or become due on Saturday, Sunday or any other day which is a
          legal bank holiday under the laws of the New York,  such payment shall
          be or become due on the next succeeding business day.

     2.   Prepayment.  The Obligor and the Holder  understand and agree that the
          ----------
          principal  amount of this Note is  intended  as loan to the Obligor in
          anticipation  of a equity or debt  offering  (the  "Offering")  by the
          Obligor.  In the event that the Offering  raises the minimum amount of
          $200,000 or more, then the entire unpaid  principal amount of the Note
          (together  with  accrued   interest   hereon)  shall  become  due  and
          immediately payable to Holder.

     3.   No Waiver.  No failure or delay by the Holder in exercising any right,
          ---------
          power or


<PAGE>

          privilege  under the Note shall operate as a waiver  thereof nor shall
          any single or partial  exercise  thereof preclude any other or further
          exercise  thereof  or  the  exercise  of any  other  right,  power  or
          privilege. The rights and remedies herein provided shall be cumulative
          and not exclusive of any rights or remedies provided by law. No course
          of dealing  between  the  Obligor  and the Holder  shall  operate as a
          waiver of any rights by the Holder.

     4.   Waiver of  Presentment  and Notice of  Dishonor.  The  Obligor and all
          -----------------------------------------------
          endorsers,  guarantors and other parties that may be liable under this
          Note hereby waive  presentment,  notice of  dishonor,  protest and all
          other demands and notices in connection with the delivery, acceptance,
          performance or enforcement of this Note.

     5.   Place of  Payment.  All  payments  of  principal  of this Note and the
          -----------------
          interest due hereon shall be made at such place as the Holder may from
          time to time designate in writing.

     6.   Events of Default. The entire unpaid principal amount of this Note and
          -----------------

          payable,  without presentment,  demand, protest or other notice of any
          kind, all of which are hereby expressly  waived, if any one or more of
          the following  events (herein  called "Events of Default")  shall have
          occurred (for any reason  whatsoever and whether such happening  shall

          of law or pursuant to or in compliance  with any judgement,  decree or
          order  of  any  court  or  any  order,   rule  or  regulation  of  any

               Obligor,  a receiver of the whole or any substantial  part of the
               Obligor's property,  and such other, judgment or decree shall not
               be vacated or set aside or stayed  with ninety (90) days from the
               date of entry thereof;

          d)   if, under the  provisions  of any other law for the relief or aid
               of debtors,  any court or  competent  jurisdiction  shall  assume
               custody  or  control  of the  whole  or any  substantial  part of
               Obligor's  property  and such  custody  or  control  shall not be
               terminated or stayed within (90) days from the date of assumption

          equity and/or by action law,  whether for the specific  performance of
          any  covenant  or  agreement  contained  in this Note or in aid of the
          exercise of any power  granted in this Note, or the Holder may proceed

     8.   Severability.  In the event that one or more of the provisions of this
          ------------

          any respect, such invalidity, illegality or unenforceability shall not
          affect  any other  provision  of this  Note,  but this  Note  shall be

          never been contained herein.

     9.   Governing Law   This Note and the right and obligations of the Obligor
          -------------
