                 AGREEMENT TO TERMINATE STOCKHOLDERS AGREEMENT

     This Agreement to Terminate Stockholders Agreement is made and entered
into as of the 4th day of August, 2003, by and among Nelnet Loan Services,
Inc., f/k/a UNIPAC Service Corporation (the "Company"), and stockholders of the
Company (and, if applicable, their respective spouses) who have executed that
certain Stockholders Agreement for UNIPAC Service Corporation dated as of March
2, 2000 (the "Stockholders Aggregate").

     WHEREAS, the parties hereto entered into the Stockholders Agreement, and
now wish to terminate the Stockholders Agreement in full in the manner
specified herein.

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants herein contained, the parties hereto agree as follows:

     1.   Termination of Stockholders Agreement. The Stockholders Agreement
shall be terminated, voided and cancelled, effective upon the closing of the
Company's initial public offering of shares of common stock of the Company.
Such termination shall be effected without further action by the parties to the
Stockholders Agreement. This Agreement to Terminate Stockholders Agreement is
conditioned upon the closing of said initial public offering, and thus shall
not terminate the Stockholders Agreement until and unless such closing occurs.

     2.   Counterparts. This Agreement to Terminate Stockholders Agreement may
be executed by the parties in counterparts, each of which shall be deemed to be
an original instrument, but all of which together shall constitute one and the
same instrument.

                                     Service Corporation
