         The Union Bank Purchase Agreement,  the Nelnet Purchase Agreement,  and
the Nebhelp  Purchase  Agreement shall be  individually  referred to herein as a
"Purchase  Agreement"  and  collectively,  as the "Purchase  Agreements".  NELN,
NELNET,  Nebhelp,  and Union  Bank are  collectively  referred  to herein as the
"Nelnet Entities")

         NELN,  Nelnet,  and  Nebhelp  have  requested  that  for an  additional
temporary 60 day period beginning on the Effective Date of this Amendment, loans
Guaranteed by the Colorado  Student Loan Program,  which are otherwise  Eligible

the Letter of Credit Agreement and the Purchase Agreements.

         Accordingly, in consideration of the foregoing and the mutual covenants
set forth herein, the parties hereto agree as follows:

                                   ARTICLE I
                                   DEFINITIONS

         Section  1.01  Defined  Terms.  All  capitalized  terms  defined in the
Purchase  Agreements,  and not  otherwise  defined  herein  shall  have the same
meanings herein as in the Purchase  Agreements.  Upon the  effectiveness of this
Amendment,  each  reference  in the Letter of Credit  Agreement  or any Purchase

shall mean and be a reference to the Letter of Credit Agreement and the Purchase

"hereunder"  and words of similar import when used in this Amendment shall refer
to  this  Amendment  as a  whole  and not to any  particular  provision  of this

"including" (and with correlative  meaning  "include") means including,  without
limiting the generality of any description  preceding such term. No provision of
this Amendment  shall be  interpreted  or constructed  against any person solely
because that person or its legal representative drafted such provision.
