         Lenders agree to undertake reasonable efforts among themselves such

         13.     GOVERNING LAW.  THIS AMENDMENT AND THE OTHER LOAN DOCUMENTS
SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE UNDER THE LAWS OF THE STATE OF
TEXAS AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA.
CHAPTER 15 OF TEXAS REVISED CIVIL STATUTES ARTICLE 5069 (WHICH REGULATES
CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL
NOT APPLY TO THE CREDIT AGREEMENT, AS AMENDED BY THIS AMENDMENT, OR THE NOTES.

         14.     Maximum Interest Rate.  Regardless of any provisions contained
in this Amendment or in any other Loan Documents, Lenders shall never be deemed
to have contracted for or be entitled to receive, collect or apply as interest
on the Notes or otherwise any amount in excess of the maximum rate of interest
permitted to be charged by applicable law, and if Lenders ever receive, collect
or apply as interest any such excess, or if acceleration of the maturity of the
Notes or if any prepayment by Borrower results in Borrower having paid any
interest in excess of the maximum rate, such amount which would be excessive
interest shall be applied to the reduction of the unpaid principal balance of
the Notes for which such excess was received, collected or applied, and, if the
principal balances of Notes are paid in full, any remaining excess shall
forthwith be paid to Borrower.  All sums paid or agreed to be paid to Lenders
for the use, forbearance or detention of the indebtedness evidenced by the
Notes and/or the Credit Agreement, as amended by this Amendment, shall, to the
extent permitted by applicable law, be amortized, prorated, allocated and
spread throughout the full term of such indebtedness until payment in full so
that the rate or amount of interest on account of such indebtedness does not
exceed the maximum lawful rate permitted under applicable law. In determining
whether or not the interest paid or payable under any specific contingency
exceeds the maximum rate of interest permitted by law, Borrower and Lenders
shall, to the maximum extent permitted under applicable law, (i) characterize
any non-principal payment as an expense, fee or premium, rather than as
interest; and (ii) exclude voluntary prepayments and the effect thereof; and
(iii) compare the total amount of interest contracted for, charged or received
with the total amount of interest which could be contracted for, charged or
received throughout the entire contemplated term of the Notes at the maximum
lawful rate under applicable law.

         15.     Counterparts.  This Amendment may be separately executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute one
and the same Amendment.

         16.     WAIVER OF TRIAL BY JURY.  EACH DAISYTEK CORPORATION WAIVES ANY
AND ALL RIGHTS THAT IT MAY HAVE TO A TRIAL BY JURY ON ANY CLAIM, COUNTERCLAIM
OR OTHER ACTION, OF ANY NATURE WHATSOEVER, RELATING TO OR ARISING OUT OF THIS
AMENDMENT, ANY OF THE OTHER LOAN DOCUMENTS OR THE OBLIGATIONS.  EACH DAISYTEK
CORPORATION ACKNOWLEDGES THAT THE FOREGOING JURY TRIAL WAIVER IS A MATERIAL
INDUCEMENT TO EACH LENDER'S ENTERING INTO THIS AMENDMENT AND THE OTHER LOAN
DOCUMENTS AND THAT EACH LENDER IS RELYING ON SUCH WAIVER IN ITS FUTURE DEALINGS
WITH SUCH CORPORATION.  EACH SUCH CORPORATION WARRANTS AND REPRESENTS TO EACH
LENDER THAT SUCH CORPORATION HAS REVIEWED THE FOREGOING JURY TRIAL WAIVER WITH
ITS





FIFTH AMENDMENT TO CREDIT AGREEMENT - Page 5
<PAGE>   6
LEGAL COUNSEL AND HAS KNOWINGLY AND VOLUNTARILY WAIVED ITS JURY TRIAL RIGHTS
FOLLOWING CONSULTATION WITH SUCH LEGAL COUNSEL.  IN THE EVENT OF LITIGATION,
THE FOREGOING JURY TRIAL WAIVER MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY
THE COURT.

         17.     WAIVER OF CONSUMER/DTPA RIGHTS.  EACH DAISYTEK CORPORATION
HEREBY WAIVES ALL OF ITS RIGHTS UNDER THE TEXAS DECEPTIVE TRADE
PRACTICES-CONSUMER PROTECTION ACT (TEX. BUS. & COM. CODE Section  17.41 ET
SEQ.), A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND PROTECTIONS, AND
REPRESENTS AND WARRANTS TO EACH LENDER THAT SUCH CORPORATION (A) HAS KNOWLEDGE
AND EXPERIENCE IN FINANCIAL AND BUSINESS MATTERS THAT ENABLE SUCH CORPORATION
TO EVALUATE THE MERITS AND RISKS OF THE TRANSACTIONS CONTEMPLATED BY THIS
AMENDMENT, (B) IS NOT IN A SIGNIFICANTLY DISPARATE BARGAINING POSITION, AND (C)
IS REPRESENTED BY LEGAL COUNSEL IN CONNECTION WITH SUCH TRANSACTIONS.

         18.     OTHER AGREEMENTS.  THE CREDIT AGREEMENT, AS AMENDED BY THIS
AMENDMENT, AND THE OTHER LOAN DOCUMENTS EMBODY THE ENTIRE AGREEMENT BETWEEN THE
PARTIES AND SUPERSEDE ALL PRIOR AGREEMENTS AND UNDERSTANDINGS, IF ANY, RELATING
TO THE SUBJECT MATTER HEREOF AND THEREOF.  THE WRITTEN CREDIT AGREEMENT, AS
AMENDED BY THIS AMENDMENT,  REPRESENTS THE FINAL AGREEMENT AMONG THE PARTIES
AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT
ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO ORAL AGREEMENTS AMONG THE
PARTIES.
