APPLICABLE LAW OR AFFECT THE RIGHT OF AGENT PAYEE OR ANY EXISTING LENDER TO
BRING ANY ACTION OR PROCEEDING AGAINST ANY MAKER OR ANY OF ITS PROPERTIES IN THE
COURTS OF ANY OTHER JURISDICTIONS.

     (h)  Jury Trial. TO THE EXTENT PERMITTED BY LAW, AGENT PAYEE, EACH MAKER
          ----------
AND, BY ACCEPTING THE BENEFITS HEREOF, EACH EXISTING LENDER, HEREBY IRREVOCABLY
WAIVE, THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM
OR OTHER PROCEEDING ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS NOTE, ANY
RIGHTS OR OBLIGATIONS HEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS AND
OBLIGATIONS. The scope of this waiver is intended to be all-encompassing of any
and all Disputes that may be filed in any court and that relate to the subject
matter of this transaction, including contract claims, tort claims, breach of
duty claims and all other common law and statutory claims. Each party hereto
acknowledges that this waiver is a material inducement to enter into a business
relationship, that each has already relied on this waiver in entering into this
Note, and that each will continue to rely on this waiver in their related future
dealings. Each party hereto further warrants and represents that it has reviewed
this waiver with its legal counsel and that it knowingly and voluntarily waives
its jury trial rights following consultation with legal counsel. In the event of
litigation, this Note may be filed as a written consent to a trial by the court.

     (i)  Binding Arbitration. Upon demand of any party, whether made before or
          -------------------
after institution of any judicial proceeding, any dispute, claim or controversy
arising out of, connected with or relating to this Note ("Disputes"), between or
                                                          --------
among parties to this Note shall be resolved by binding arbitration as provided
herein. Institution of a judicial proceeding by a party does not waive the right
of that party to demand arbitration hereunder. Disputes may include, without
limitation, tort claims, counterclaims, claims brought as class actions, claims
arising from this Note executed in the future, or claims concerning any aspect
of the past, present or future relationships arising out of or connected with
this Note. Arbitration shall be conducted under and governed by the Commercial
Financial Disputes Arbitration Rules (the "Arbitration Rules") of the American
                                           -----------------
Arbitration Association and Title 9 of the U.S. Code. All arbitration hearings
shall be conducted in Charlotte, North Carolina. The expedited procedures set
forth in Rule 51, et seq. of the Arbitration Rules shall be applicable to claims
                  -- ---
of less than $1,000,000. All applicable statutes of limitation shall apply to
any Dispute. A judgment upon the award may be entered in any court having
jurisdiction. The panel from which

                                       8
<PAGE>

all arbitrators are selected shall be comprised of licensed attorneys. The
single arbitrator selected for expedited procedure shall be a retired judge from
the highest court of general jurisdiction, state or federal, of the state where
the hearing will be conducted.

     (j)  Preservation of Certain Remedies. Notwithstanding the preceding
          --------------------------------
binding arbitration provisions, the parties hereto preserve, without diminution,
certain remedies that such Persons may employ or exercise freely, either alone,
in conjunction with or during a Dispute. Each such Person shall have and hereby
reserves the right to proceed in any court of proper jurisdiction or by self
help to exercise or prosecute the following remedies: (i) all rights to
foreclose against any real or personal property or other security by exercising
a power of sale granted in this Note or under applicable law or by judicial
foreclosure and sale, (ii) all rights of self help including peaceful occupation
of property and collection of rents, set off, and peaceful possession of
property, (iii) obtaining provisional or ancillary remedies including injunctive
relief, sequestration, garnishment, attachment, appointment of receiver and in
filing an involuntary bankruptcy proceeding, and (iv) when applicable, a
judgment by confession of judgment. Preservation of these remedies does not
limit the power of an arbitrator to grant similar remedies that may be requested
by a party in a Dispute.

     (k)  Marshalling; Reversal of Payments. Agent Payee and Existing Lenders
          ---------------------------------
shall be under no obligation to marshal any assets in favor of any Maker or any
other party or against or in payment of any or all of the Obligations. To the
extent any Maker makes a payment or payments to Agent Payee or any Existing
Lender or Agent Payee or any Existing Lender receives any payment or proceeds of
the Collateral for any Maker's benefit which payments or proceeds or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside and/or required to be repaid to a trustee, receiver or any other party
under any bankruptcy law, state or federal law, common law or equitable cause,
then, to the extent of such payment or proceeds repaid, the Obligations or part
thereof intended to be satisfied shall be revived and continued in full force
and effect as if such payment or proceeds had not been received by Agent Payee.

     (l)  Injunctive Relief; Punitive Damages. Each Maker recognizes that, in
          -----------------------------------
the event any Maker fails to perform, observe or discharge any of its respective
obligations or liabilities under this Note, any remedy of law may prove to be
inadequate relief to Agent Payee. Therefore, each Maker agrees that Agent Payee,
at Agent Payee's option, shall be entitled to temporary and permanent injunctive
relief in any such case without the necessity of proving actual damages. Each
Maker hereby waives any right or claim to punitive or exemplary damages that it
may now have or may arise in the future in connection with any Dispute, whether
such Dispute is resolved through arbitration or judicially. Each Maker shall not
have a remedy of punitive or exemplary damages against any other party in any
Dispute and each Maker hereby waives any right or claim to punitive or exemplary
damages it has now or which may arise in the future in connection with any
Dispute whether the Dispute is resolved by arbitration or judicially.

     (m)  Certain Pledges or Assignments. This Note shall be binding upon and
          ------------------------------
inure to the benefit of each Maker, the Agent Payee and the Existing Lenders,
all future holders of

                                       9
<PAGE>

this Note, and their respective successors and assigns, except that each Maker
shall not assign or transfer any of its rights or obligations under this
Agreement without the prior written consent of each Existing Lender. Each
Existing Lender may, with the consent of the Agent Payee, which consent shall
not be unreasonably withheld, assign to on or more Eligible Assignees all or an
undivided portion of its interests, rights and obligations under this Agreement.
Nothing herein shall prohibit Agent Payee or any Existing Lender from pledging
or assigning this Note or its interest hereunder to any Federal Reserve Bank in
accordance with Applicable Law.

     (n)  Amendments, Waivers and Consents; Extensions, Renewals of Time. Any
          --------------------------------------------------------------
term, covenant, agreement or condition of this Note may be amended or waived by
Agent Payee, and any consent given by Agent Payee , if, but only if, such
amendment, waiver or consent is in writing signed by Agent Payee and, in the
case of an amendment, signed by Makers. Makers and any endorser of this Note
hereby consent to renewals and extensions of time at or after the maturity
hereof, without notice, and hereby waive diligence, presentment, protest, demand
and notice of every kind and, to the full extent permitted by law, the right to
plead any statute of limitations as a defense to any demand hereunder.

     (o)  Performance of Duties. The Credit Parties' obligations under this Note
          ---------------------
shall be performed by the Credit Parties at their sole cost and expense.

     (p)  All Powers Coupled with Interest. All powers of attorney and other
          --------------------------------
authorizations granted to Agent Payee and any Persons designated by Agent Payee
pursuant to any provisions of this Note shall be deemed coupled with an interest
and shall be irrevocable so long as any of the Obligations remain unpaid or
unsatisfied or this Note has not been terminated.

     (q)  Survival Agreements. Notwithstanding anything in this Note or implied
          -------------------
by law to the contrary, (a) the agreements of Makers set forth in Section 7(b)
                                                                  -----------
and 7(d), (b) any other indemnities of Makers to which Agent Payee is entitled
    ---
under this Note, shall survive the payment of the Obligations and the
termination of this Note.

     (r)  Construction of Agreement. Each of the parties hereto acknowledges
          -------------------------
that it has been represented by counsel in the negotiation and documentation of
the terms of this Note, that it has had full and fair opportunity to review and
revise the terms of this Note, and that this Note has been drafted jointly by
all of the parties hereto. Accordingly, each of the parties hereto acknowledges

favor of another party.

     (s)  Titles and Captions. Titles and captions of Articles, Sections and
          -------------------

the provisions of this Note.

     (t)  Severability of Provisions. Any provision of this Note which is
          --------------------------
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective only to the extent of such prohibition or unenforceability
without invalidating the remainder of such

                                       10
<PAGE>

provision or the remaining provisions hereof or thereof or affecting the
validity or enforceability of such provision in any other jurisdiction.

     (u)  Counterparts. This Note and any amendments, waivers, consents, or
          ------------
supplements may be executed 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 together shall
constitute but one and the same instrument.

     (v)  Term of Note. This Note shall remain in effect from the date hereof
          ------------
through and including the date upon which all Obligations shall have been
indefeasibly and irrevocably paid and satisfied in full.
