beyond the Concentration Bank's reasonable control, including, but not limited
to, legal constraint, emergency conditions, action or inaction of governmental,
civil or military authority, fire, strike, lockout or other labor dispute, war,
riot, theft, flood, earthquake or other natural disaster, breakdown of public

Concentration Bank's reasonable belief that the action would have violated any
guideline, rule or regulation of any governmental authority.

                  (d)      Notwithstanding any of the other provisions of this
Agreement, in the event of the commencement of a case pursuant to Title 11,
United States Code, filed by or against the Borrower, or in the event of the
commencement of any similar case under then applicable federal or state law
providing for the relief of debtors or the protection of creditors by or
against the Borrower, the Concentration Bank may act reasonably to comply with
all applicable provisions of governing statutes and neither the Borrower, Agent
or any Lender shall assert any claim against the Concentration Bank for doing
so.

                  SECTION 18.       Jurisdiction. ALL JUDICIAL PROCEEDINGS
BROUGHT AGAINST THE BORROWER ARISING OUT OF OR RELATING TO THIS AGREEMENT MAY
BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE

the Borrower at its address specified on the signature pages hereof, such
service being hereby acknowledged by the Borrower to be sufficient for personal
jurisdiction in any action against the Borrower in any such court and to be
otherwise effective and binding service in every respect. Nothing herein shall
affect the right to serve process in any other manner permitted by law or shall
limit the right of the Agent or the Concentration Bank to bring proceedings

                  SECTION 20.       Governing Law.

                  (a)      EXCEPT AS EXPRESSLY PROVIDED HEREIN, THIS AGREEMENT
SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS
PRINCIPLES. NOTWITHSTANDING THE FOREGOING, THE SECURITY INTERESTS GRANTED
HEREUNDER SHALL BE GOVERNED AND DETERMINED BY THE UNIFORM COMMERCIAL CODE IN
EFFECT IN KENTUCKY, AS SUCH CODE MAY BE AMENDED (INCLUDING AMENDMENTS RELATED
TO REVISED ARTICLE 9) OR SUCH OTHER APPLICABLE LAW (AS AMENDED) THAT INCREASES
THE VALIDITY AND ENFORCEABILITY OF THE SECURITY INTERESTS GRANTED HEREUNDER, IT
BEING THE INTENT OF THE PARTIES THAT THE SECURITY INTERETS HEREUNDER BE GIVEN
THE BROADEST POSSIBLE SCOPE.

                  (b)      The Borrower, the Agent, and the Concentration Bank
agree that for purposes of Article 9. Secured Transactions; Sales of Accounts,
Contract Rights and Chattel Paper, of Kentucky's version of the Uniform
Commercial Code, KY ST ss.ss. 355.9-101 - 9-710, the jurisdiction of the
Concentration Bank and Concentration Account is Kentucky.

                  SECTION 21.       Successors and Assigns. Whenever in this
Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party and all covenants,
promises, and agreements by or on behalf of the Borrower or by and on behalf of
the Concentration Bank shall bind and inure to the benefit of the successors
and assigns of the Borrower, the Concentration Bank, the Agent, and the
Lenders.

                  SECTION 22.       Execution in Counterparts. This Agreement
may be executed via facsimile and in any number of counterparts, and by
different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
taken together shall constitute but one and the same instrument; signature
pages may be detached from multiple separate counterparts and attached to a
single counterpart so that all signature pages are physically attached to the
same document. The Borrower and the Concentration Bank each hereby acknowledges
receipt of a true, correct, and complete counterpart of this Agreement.

                  SECTION 23.       Severability. Any provision of this
Agreement that is prohibited or unenforceable in any jurisdiction shall, as to
such provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions
of this Agreement or affecting the validity or enforceability of such provision
in any other jurisdiction.

                  SECTION 24.       Termination. This Agreement shall terminate
upon the earlier of (i) payment in full of all monetary obligations of the
Borrower under the Credit Agreement and the termination of the commitments
thereunder, and (ii) effectiveness of the resignation of the Concentration Bank

                  SECTION 25.       Headings. The section headings in this
Agreement are inserted for convenience of reference and shall not be considered
a part of this Agreement or used in its interpretation.

                  SECTION 26.       Agreement Duly Authorized. All parties
hereto represent and warrant that they have taken all actions and obtained all
authorizations, consents and approvals as are conditions precedent to their
authority to execute this Agreement.

                  SECTION 27.       Notice of Legal Process. If the
Concentration Bank receives any notice of legal process of any kind relating to
the Borrower, the Concentration Bank shall make a reasonable effort to give
oral notice to the Agent and the Borrower of such legal process.

                  SECTION 28.       Indemnity. The Borrower agrees to
indemnify, defend and hold harmless Concentration Bank and its affiliates,
directors, officers, employees, agents, successors and assigns (each an
"INDEMNITEE") from and against any and all liabilities, losses, claims,
damages, demands, costs and expenses of every kind (including but not limited
to costs incurred as a result of items being deposited in the Concentration
Account and being unpaid for any reason, reasonable attorney's fees and the
reasonable charges of Concentration Bank's in-house counsel) incurred or
sustained by any Indemnitee arising out of Concentration Bank's performance of
the services contemplated by this Agreement, except to the extent such
liabilities, losses, claims, damages, demands, costs and expenses are the
direct result of Concentration Bank's gross negligence or willful misconduct.
Compliance by Concentration Bank with its standard procedures for the services
provided hereunder in all material respects shall be deemed to be the exercise
of ordinary care by Concentration Bank, provided that such standard procedures
comply with all provisions of applicable law and good banking practices.
Concentration Bank shall have no obligation to review or confirm that any
actions taken pursuant to this Concentration Bank Agreement comply with the
Credit Agreement or any other agreement or document. The provisions of this
Section shall survive termination of the Concentration Account. To the extent
that the undertaking to indemnify and hold harmless set forth in this Section
may be unenforceable because it is violative of any law or public policy, the
Borrower shall contribute the maximum portion that it is permitted to pay and
satisfy under applicable law, to the payment and satisfaction of all
indemnified liabilities incurred by the Indemnitees or any of them. Each
Indemnitee, as soon as reasonably practicable, shall notify the Borrower and
the Agent of the commencement of any legal proceeding by a third Person under
which any indemnified liability might arise. The Borrower shall have the option
to participate in the defense of all claims under which any indemnified
liability might arise, but neither the Agent nor the Borrower shall have the
option to compel any Indemnitee to employ counsel not of the Indemnitee's
choosing.

                  SECTION 29.       No Right of Set-Off. Except as expressly
provided in Section 8 or Section 28, the Concentration Bank shall have no right
to set off and appropriate or recoup any amount with respect to any banking
relationship between Concentration Bank and Borrower or any of its Subsidiaries
or otherwise; provided, however, that nothing in this Agreement is intended to
effect or impair (i) the rights of the Concentration Bank under a Pledge
Agreement from the Borrower in favor of the Concentration Bank with respect to
a Certificate of Deposit issued by the Concentration Bank in the principal
amount of $30,000 and any proceeds thereof, including any proceeds deposited in
any Deposit Account, or (ii) the Concentration Bank's right to receive payments
from the Borrower under a VISA Corporate Card Arrangement with the
Concentration Bank with a credit limit of $25,000 ("Corporate Card
Obligations").
