     FOR VALUE RECEIVED, FULLNET COMMUNICATIONS, INC., an Oklahoma corporation,
with an address of 201 Robert S. Kerr Avenue, Suite 210, Oklahoma City, Oklahoma
73102 (the "Maker"), does promise to pay to the order of NORTHEAST RURAL
SERVICES, a subsidiary of Northeast Oklahoma Electric Cooperative, Inc., a
cooperative corporation organized under the laws of Oklahoma, (the "Holder") at
such place as may be designated by the Holder of this promissory note (the
"Note"), on the above specified maturity date, a single payment equal to the
lesser of (i) $30,000 or (ii) the product obtained by multiplying $30,000 by a
fraction, the denominator of which is equal to the greater of (i) 1,383 or (ii)
the number of active customers purchased by the Buyer pursuant to this Agreement
and the numerator of which is the number of active customers purchased by the
Buyer that are still active on the day before said payment is due. For purposes
of this calculation an active customer is one who is using the Rectec.com and/or
the Rectec.net domain for e-mail purposes and made a payment equal to the cost
of one month's Internet access to the Seller, the Buyer, or Inter.Net within the
30 days prior to the date of measurement.

     In the event that the above specified maturity date is not a "Business Day"
(as such term is hereafter defined), the date on which such payment is due shall
be extended to the next succeeding Business Day with the same force and effect
as if made on the date of payment. "Business Day" means a day other than a
Saturday, Sunday or other day on which national banks in Oklahoma City, Oklahoma
are authorized to be closed.

     Capitalized terms used herein which are not otherwise defined shall have
the meaning as described in that certain Asset Purchase Agreement between the
parties dated of even date herewith (the "Asset Purchase Agreement").

     EVENT OF DEFAULT. Except as set forth in the preceding section, the failure
to pay principal when due shall be an event of default.

     RIGHT OF PREPAYMENT. At any time from the date hereof to the due date, the
Maker may prepay the entire principal sum or any portion thereof, without
penalty or restriction.

     AMENDMENT AND WAIVER. This Note may not be changed, modified or amended, or
terminated, nor may any of its provision be waived, except by an agreement in
writing signed by the party against whom enforcement thereof is sought.

     CHOICE OF LAW. This Note shall be governed by and construed in accordance
with the laws of the State of Oklahoma.

     PROMISES BINDING. This Note shall be binding upon the Maker and its
successors and assigns.



     IN WITNESS WHEREOF, the Maker has caused this instrument to be duly signed
as of the date first set forth above.
