<PAGE>

1965 and all regulations promulgated thereunder, each as amended from time to
time (the "Higher Education Act") or on Collateral reports delivered to Lender.

       (b)  Any officer, employee or agent of Lender shall have the right, at
any time or times hereafter, in the name of Lender or its nominee (including
Borrower), to verify the validity, amount or any other matter relating to any
Student Loan or any Loan and Security Agreement by mail, telephone, or
otherwise. Lender or its designee may at any time notify LSA Debtors or any
Student Loan Debtor that a security interest has been granted in the Loan and
Security Agreements and the Student Loans to Lender and after default by
Borrower hereunder collect the same directly and charge all collection costs and
expenses to Borrower's account.

Lender shall credit Borrower's account with the net amounts collected from such
disputed Loan and Security Agreements or Student Loans, after expenses of
collection.

       (d)  Effective upon any Event of Default, Borrower (and Borrower ELT on
behalf of Borrower) hereby grant a power of attorney and all necessary
authorization to Lender to maintain any and all collection procedures with
respect to the Collateral, including with respect to Student Loans contained in
the Collateral, filing, pursuing and recovering claims against Guarantors for
Guarantee Payments and taking steps to enforce such Student Loans such as
commencing a legal proceeding to enforce a Student Loan in the name of the
Borrower or the Borrower ELT.

       2.5  Liens. Borrower as to the Loan and Security Agreement, and the
Borrower ELT as to the Student Loans, has good and marketable title to its
respective Collateral, and the Liens granted to Lender in this Agreement are
enforceable, and upon (a) receipt by Lender of an Acknowledgment and Acceptance
of Bailment Notice from Great Lakes Higher Education Servicing Corporation as
bailee on Lender's behalf, and (b) the filing of financing statements naming the
LSA Debtor, the Borrower and the Borrower ELT have been duly filed in the

Collateral.

hereby irrevocably makes, constitutes and appoints Lender (and any of Lender's
officers, employees or agents designated by Lender) as Borrower's true and
lawful attorney with power to sign the name of Borrower on any such documents.

       (b)  If any Collateral, including proceeds, consists of a letter of
credit, advice of credit, instrument, money, negotiable documents, chattel paper
or similar property (collectively, "Negotiable Collateral") Borrower shall,
immediately upon receipt thereof, deliver actual physical possession of the
Negotiable Collateral to Lender with such endorsements as may be necessary.

       (c)  Lender may inspect and verify Borrower's books and records at any
time or times hereafter, during usual business hours, in order to verify the
amount or condition of the Collateral, or any other matter relating to the
Collateral or Borrower's financial condition. Borrower shall promptly deliver to
Lender copies of all books and records requested by Lender.

       2.7  Other Amounts Deemed Loans. If Borrower fails to pay any tax,
assessment, government charge or levy or to maintain insurance within the time
permitted by this Agreement or the Credit Agreement, or to discharge any Lien
prohibited hereby, or to comply with any other obligation, Lender may, but shall
not be required to, pay, satisfy, discharge or bond the same of the account of
Borrower, and to the extent permitted by law and all monies so paid out shall be
secured by the Collateral.

       2.8  Borrower Remains Liable. Borrower shall remain liable under any
contracts and agreements included in the Collateral to perform all of its duties
and obligations thereunder to the same extent as if this Agreement had not been
executed, and Lender shall not have any obligation or liability under such
contracts and agreements by reason of this Agreement or otherwise.

agreement herein and the failure or inability of Borrower to cure such default

good faith judgement is incapable

       (a)  Lender may resort to the rights and remedies of a Lender under the

and remove it and any records pertaining thereto and/or remain on such premises
and use it for the purpose of collecting, preparing and disposing of the
Collateral;

       (b)  Borrower shall upon request of Lender assemble the Collateral and
any records pertaining thereto and make them available at a place designated by

     WHEREAS, Borrower, the Borrower ELT and Lender are parties to a Security
Agreement, dated September 17, 2001 (the "Security Agreement"); and

     WHEREAS, Borrower, the Borrower ELT and Lender are parties to that First
Amendment to Security Agreement, dated January 7, 2002 (the "First Amendment");
and

     WHEREAS, Borrower, the Borrower ELT and Lender now desire to enter into
this Second Amendment to Security Agreement to correct a typographical error, to

     NOW, THEREFORE, in consideration of the mutual promises and covenants set
forth herein and for other good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, intending to be legally bound, the
parties hereto agree as follows:

Amendment, the parties hereby ratify, confirm and approve in all respects the

Except as expressly amended hereby, the Security Agreement, as amended by the
First Amendment, shall continue in full force and effect in accordance with its
terms.
