FOR VALUE RECEIVED, the undersigned Borrower unconditionally (and jointly and
severally, if more than one) promises to pay to the order of Bank, its
successors and assigns, without setoff, at its offices indicated at the
beginning of this Note, or at such other place as may be designated by Bank, the
principal amount of UP TO TEN MILLION AND NO/100 DOLLARS ($10,000,000.00), or
so much thereof as may be advanced from time to time in immediately available
funds, together with interest computed daily on the outstanding principal
balance hereunder, at an annual interest rate, and in accordance with the
payment schedule, indicated below.

[THIS NOTE CONTAINS SOME PROVISIONS PRECEDED BY BOXES. IF A BOX IS MARKED, THE
PROVISION APPLIES TO THIS TRANSACTION; IF IT IS NOT MARKED, THE PROVISION DOES
NOT APPLY TO THIS TRANSACTION.]

1.   RATE.

[ ] PRIME RATE. The Rate shall be the Prime Rate, plus ______________________
percent, per annum. The "Prime Rate" is the fluctuating rate of interest
established by Bank from time to time, at its discretion, whether or not such
rate shall be otherwise published. The Prime Rate is established by Bank as an
index and may or may not at any time be the best or lowest rate charged by Bank
on any loan.

[ ] FIXED RATE. The Rate shall be fixed at ___________________ percent per
annum.

[X] OTHER. The rate shall be thirty-day LIBOR, plus two hundred fifty basis
points (2.50%) per annum, as such Rate is determined by the Bank and changes
from time to time.

Notwithstanding any provision of this Note, Bank does not intend to charge and
Borrower shall not be required to pay any amount of interest or other charges in
excess of the maximum permitted by the applicable law of the State of North
Carolina; if any higher rate ceiling is lawful, then that higher rate ceiling
shall apply. Any payment in excess of such maximum shall be refunded to Borrower
or credited against principal, at the option of Bank.

2.   ACCRUAL METHOD. Unless otherwise indicated, interest at the Rate set forth
above will be calculated by the 365/360 day method (a daily amount of interest
is computed for a hypothetical year of 360 days; that amount is multiplied by
the actual number of days for which any principal is outstanding hereunder). If
interest is not to be computed using this method, the method shall be:
________________________________________________________________________________
________________________________________________________________________________
________________________________________________________________________________

3.  RATE CHANGE DATE. Any Rate based on a fluctuating index or base rate will
change, unless otherwise provided, each time and as of the date that the index
or base rate changes. The Rate may also change in accordance with the interest
rate provisions of the Loan Agreement of even date herewith between the Borrower
and the Bank (the "Loan Agreement"). In the event any index is discontinued,
Bank shall substitute an index determined by Bank to be comparable, in its sole
discretion.

4.   PAYMENT SCHEDULE. All payments received hereunder shall be applied first to
the payment of any expense or charges payable hereunder or under any other loan
documents executed in connection with this Note, then to interest due and
payable, with the balance applied to principal, or in such other order as Bank
shall determine at its option.

[ ] PRINCIPAL PLUS ACCRUED INTEREST. Principal shall be paid in consecutive
equal installments of $_______________________, plus accrued interest, payable
[ ] monthly, [ ] quarterly or
[ ]_________________________________________________, commencing on
______________________________, 19_______, and continuing on the [ ] same day,
[ ] last day of each successive month, quarter or other period (as applicable)
thereafter, with a final payment of all unpaid principal and accrued interest
due on ___________________________, 19______.

[ ] FIXED PRINCIPAL AND INTEREST. Principal and interest shall be paid in
consecutive equal installments of $______________________________, payable
[ ] monthly, [ ] quarterly or [ ]________________________________________,
commencing on _______________________________, 19_______, and continuing on the
[ ] same day, [ ] last day of each successive month, quarter or other period (as
applicable) thereafter, with a final payment of all unpaid principal and
interest due thereon on ____________________________________________, 19______.
If, on any payment date, accrued interest exceeds the installment amount set
forth above, Borrower will also pay such excess as and when billed.

[X] SINGLE PRINCIPAL PAYMENT. Principal shall be paid in full in a single
payment on NOVEMBER 30, 2001. Interest thereon shall be paid [ ] at maturity, or
else [X] monthly, [ ] quarterly or [ ] _________________________________,
commencing on August 2, 2000, and continuing on the [X] same day, [ ] last day
of each successive month, quarter or other period (as applicable) thereafter,
with a final payment of all unpaid interest at the stated maturity of this Note.

[X] OTHER. This is the "Overline Note" described in the Second Amended and
Restated Loan Agreement dated June 30, 2000 (the "Loan Agreement"), to which
reference is hereby made for additional provisions affecting this Note.

                                      -1-

5.   REVOLVING FEATURE.

[X] Borrower may borrow, repay and reborrow hereunder at the times permitted
under the Loan Agreement, up to a maximum aggregate amount outstanding at any
one time equal to the principal amount of this Note, provided that Borrower is
not in default under any provision of this Note, any other documents executed in
connection with this Note, or any other note or other loan documents now or
hereafter executed in connection with any other obligation of Borrower to Bank,
and provided that the borrowings hereunder do not exceed any borrowing base or
other limitation on borrowings by Borrower. Bank shall incur no liability for
its refusal to advance funds based upon its determination that any conditions of
such further advances have not been met. Bank records of the amounts borrowed
from time to time shall be conclusive proof thereof.

     [ ] UNCOMMITTED FACILITY. Borrower acknowledges and agrees that,
     notwithstanding any provisions of this Note or any other documents executed
     in connection with this Note, Bank has no obligation to make any advance,
     and that all advances are at the sole discretion of Bank.

     [ ] OUT-OF-DEBT PERIOD. For a period of at least ________________
     consecutive days during [ ] each fiscal year, [ ] any consecutive 12-month
     period, Borrower shall fully pay down the balance of this Note, so that no
     amount of principal or interest and no other obligation under this Note
     remains outstanding.

6.   AUTOMATIC PAYMENT.

[X] Borrower has elected to authorize Bank to effect payment of sums due under
this Note by means of debiting Borrower's account number 000658763107. This
authorization shall not affect the obligation of Borrower to pay such sums when
due, without notice, if there are insufficient funds in such account to make
such payment in full on the due date thereof, or if Bank fails to debit the
account.

7.   WAIVERS, CONSENTS AND COVENANTS. Borrower, any indorser or guarantor
hereof, or any other party hereto (individually an "Obligor" and collectively
"Obligors") and each of them jointly and severally: (a) waive presentment,
demand, protest, notice of demand, notice of intent to accelerate, notice of
acceleration of maturity, notice of protest, notice of nonpayment, notice of
dishonor, and any other notice required to be given under the law to any Obligor
in connection with the delivery, acceptance, performance, default or enforcement
of this Note, any indorsement or guaranty of this Note, or any other documents
executed in connection with this Note or any other note or other loan documents
now or hereafter executed in connection with any obligation of Borrower to Bank
(the "Loan Documents"); (b) consent to all delays, extensions, renewals or other
modifications of this Note or the Loan Documents, or waivers of any term hereof
or of the Loan Documents, or release or discharge by Bank of any of Obligors, or
release, substitution or exchange of any security for the payment hereof, or the
failure to act on the part of Bank, or any indulgence shown by Bank (without
notice to or further assent from any of Obligors), and agree that no such
action, failure to act or failure to exercise any right or remedy by Bank shall
in any way affect or impair the obligations of any Obligors or be construed as a
waiver by Bank of, or otherwise affect, any of Bank's rights under this Note,
under any indorsement or guaranty of this Note or under any of the Loan
Documents; and (c) agree to pay, on demand, all costs and expenses of collection
or defense of this Note or of any indorsement or guaranty hereof and/or the
enforcement or defense of Bank's rights with respect to, or the administration,
supervision, preservation, or protection of, or realization upon, any property
securing payment hereof, including, without limitation, reasonable attorney's
fees, including fees related to any suit, mediation or arbitration proceeding,
out of court payment agreement, trial, appeal, bankruptcy proceedings or other
proceeding, in such amount as may be determined reasonable by any arbitrator or
court, whichever is applicable.

8.   PREPAYMENTS. Prepayments may be made in whole or in part at any time on any
loan. All prepayments of principal shall be applied in the inverse order of
maturity, or in such other order as Bank shall determine in its sole discretion.

9.   DELINQUENCY CHARGE. To the extent permitted by law, a delinquency charge
may be imposed in an amount not to exceed four percent (4%) of the unpaid
portion of any payment that is more than fifteen days late. Unless the terms of
this Note call for repayment of the entire balance of this Note (both principal
and interest) in a single payment and not for installments of interest or
principal and interest, the 4% delinquency charge may be imposed not only with
respect to regular installments of principal or interest or principal and
interest, but also with respect to any other payment in default under this Note
(other than a previous delinquency charge), including without limitation, a
single payment of principal due at the maturity of this Note. In the event any
installment, or portion thereof, is not paid in a timely manner, subsequent
payments will be applied first to the past due balance (which shall not include
any previous delinquency charges), specifically to the oldest maturing
installment, and a separate delinquency charge will be imposed for each payment
that becomes due until the default is cured.

10.  EVENTS OF DEFAULT. The following are events of default hereunder: (a)
subject to the tolling of any applicable cure period, the failure to pay or
perform any obligation, liability or indebtedness of any Obligor to Bank, or to
any affiliate or subsidiary of Bank of America Corporation, whether under this
Note or any Loan Documents, as and when due (whether upon demand, at maturity or
by acceleration); (b) subject to the tolling of any applicable cure period, the
failure to pay or perform any other obligation, liability or indebtedness of any
Obligor to any other party; (c) the death of any Obligor (if an individual); (d)
the resignation or withdrawal of any partner or a material owner/guarantor of
Borrower, as determined by Bank in its sole discretion; (e) the commencement of
a proceeding against any Obligor for dissolution or liquidation, the voluntary
or involuntary termination or dissolution of any Obligor or the merger or
consolidation of any Obligor with or into another entity; (f) the insolvency of,
the business failure of, the appointment of a custodian, trustee, liquidator or
receiver for or for any of the property of, the assignment for the benefit of
creditors by, or the filing of a petition under bankruptcy, insolvency or
debtor's relief law or the filing of a petition for any adjustment of
indebtedness, composition or extension by or against any Obligor; (g) the
determination by Bank that any representation or warranty made to Bank by any
Obligor in any Loan Documents or otherwise is or was, when it was made, untrue
or materially misleading; (h) the entry of a judgment against any Obligor which
Bank deems to be of a material nature, in Bank's sole discretion; (i) the
seizure or forfeiture of, or the issuance of any writ of possession, garnishment
or attachment, or any turnover order for any property of any Obligor; or (j) the
failure of Borrower's business to comply with any law or regulation controlling
its operation, the failure to comply with which would result in a material
adverse effect on Borrower.

11.  REMEDIES UPON DEFAULT. Whenever there is a default under this Note (a) the
entire balance outstanding hereunder and all other obligations of any Obligor to
Bank (however acquired or evidenced) shall, at the option of Bank, become
immediately due and payable and any obligation of Bank to permit further
borrowing under this Note shall immediately cease and terminate, and/or (b) to
the extent permitted by law, the Rate of interest on the unpaid principal shall
be increased to 4% per annum in excess of the rate previously applicable to the
balance of unpaid principal hereunder (the "Default Rate"). The provisions
herein for a Default Rate and a delinquency charge shall not be deemed to extend
the time for any payment hereunder or to constitute a "grace period" giving
Obligors a right to cure any default. At Bank's option, any accrued and unpaid
interest, fees or charges may, for purposes of computing and accruing interest
on a daily basis after the due date of this Note or any installment thereof, be
deemed to be a part of the principal balance, and interest shall accrue on a
daily compounded basis after such date at the Default Rate provided in this Note
until the entire outstanding balance of principal and interest is paid in full.
Upon a default under this Note, Bank is hereby authorized at any time, at its
option and without notice or demand to set off and charge against any deposit
accounts of any Obligor (as well as any money, instruments, securities,
documents, chattel paper, credits, claims, demands, income and any other
property, rights and interests of any Obligor), which at any time shall come
into the possession or custody or under the control of Bank or any of its
agents, affiliates or correspondents, any and all obligations due hereunder.
Additionally, Bank shall have all rights and remedies available under each of
the Loan Documents, as well as all rights and remedies available at law or in
equity.

12.  NON-WAIVER. The failure at any time of Bank to exercise any of its options
or any other rights hereunder shall not constitute a waiver thereof, nor shall
it be a bar to the exercise of any of its options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. The acceptance by Bank of any
partial payment shall not constitute a waiver of any default or of any of Bank's
rights under this Note. No waiver of any of its rights hereunder, and no
modification or amendment of this Note, shall be deemed to be made by Bank
unless the same shall be in writing, duly signed on behalf of Bank; each such
waiver shall apply only with respect to the specific instance involved, and
shall in no way impair the rights of Bank or the obligations of Obligors to Bank
in any other respect at any other time.

                                      -2-

obligations of Borrower and Bank shall be governed by and interpreted in

connection with or to enforce this Note or any indorsement or guaranty of this
Note or any Loan Documents, Obligors, and each of them, irrevocably consent to
and confer personal jurisdiction on the courts of the State of North Carolina or
the United States located within the State of North Carolina and expressly waive
any objections as to venue in any such courts. Nothing contained herein shall,
however, prevent Bank from bringing any action or exercising any rights within
any other state or jurisdiction or from obtaining personal jurisdiction by any
other means available under applicable law.

14.  PARTIAL INVALIDITY. The unenforceability or invalidity of any provision of
this Note shall not affect the enforceability or validity of any other provision
herein and the invalidity or unenforceability of any provision of this Note or
of the Loan Documents to any person or circumstance shall not affect the
enforceability or validity of such provision as it may apply to other persons or
circumstances.

15.  BINDING EFFECT. This Note shall be binding upon and inure to the benefit of
Borrower, Obligors and Bank and their respective successors, assigns, heirs and
personal representatives, provided, however, that no obligations of Borrower or
Obligors hereunder can be assigned without prior written consent of Bank.

16.  CONTROLLING DOCUMENT. To the extent that this Note conflicts with or is in
any way incompatible with any other document related specifically to the loan
evidenced by this Note, this Note shall control over any other such document,
and if this Note does not address an issue, then each other such document shall
control to the extent that it deals most specifically with an issue.

NOT APPLY TO THIS TRANSACTION.]

1.   RATE.

[ ] PRIME RATE. The Rate shall be the Prime Rate, plus ______________________
percent, per annum. The "Prime Rate" is the fluctuating rate of interest
established by Bank from time to time, at its discretion, whether or not such
rate shall be otherwise published. The Prime Rate is established by Bank as an
index and may or may not at any time be the best or lowest rate charged by Bank
on any loan.

[ ]  FIXED RATE.  The Rate shall be fixed at ___________________ percent per
annum.

[X] OTHER. The rate shall be thirty-day LIBOR, plus two hundred fifty basis
points (2.50%) per annum, as such Rate is determined by the Bank and changes

Notwithstanding any provision of this Note, Bank does not intend to charge and
Borrower shall not be required to pay any amount of interest or other charges in
excess of the maximum permitted by the applicable law of the State of North
Carolina; if any higher rate ceiling is lawful, then that higher rate ceiling
shall apply. Any payment in excess of such maximum shall be refunded to Borrower
or credited against principal, at the option of Bank.

2.   ACCRUAL METHOD. Unless otherwise indicated, interest at the Rate set forth
above will be calculated by the 365/360 day method (a daily amount of interest
is computed for a hypothetical year of 360 days; that amount is multiplied by
the actual number of days for which any principal is outstanding hereunder). If
interest is not to be computed using this method, the method shall be:

________________________________________________________________________________
________________________________________________________________________________
________________________________________________________________________________

3.   RATE CHANGE DATE. Any Rate based on a fluctuating index or base rate will
change, unless otherwise provided, each time and as of the date that the index
or base rate changes. The Rate may also change in accordance with the interest
rate provisions of the Loan Agreement of even date herewith between the Borrower

Bank shall substitute an index determined by Bank to be comparable, in its sole
discretion.

4.   PAYMENT SCHEDULE. All payments received hereunder shall be applied first to
the payment of any expense or charges payable hereunder or under any other loan
documents executed in connection with this Note, then to interest due and
payable, with the balance applied to principal, or in such other order as Bank
shall determine at its option.

[ ] PRINCIPAL PLUS ACCRUED INTEREST. Principal shall be paid in consecutive
equal installments of $_______________________, plus accrued interest, payable
[ ] monthly, [ ] quarterly or
[ ]_________________________________________________, commencing on

[ ] FIXED PRINCIPAL AND INTEREST. Principal and interest shall be paid in

5.   REVOLVING FEATURE.

[X] Borrower may borrow, repay and reborrow hereunder at any time, up to a
maximum aggregate amount outstanding at any one time equal to the principal
amount of this Note, provided that Borrower is not in default under any
provision of this Note, any other documents executed in connection with this
Note, or any other note or other loan documents now or hereafter executed in
connection with any other obligation of Borrower to Bank, and provided that the
borrowings hereunder do not exceed any borrowing base or other limitation on
borrowings by Borrower. Bank shall incur no liability for its refusal to advance
funds based upon its determination that any conditions of such further advances
have not been met. Bank records of the amounts borrowed from time to time shall
be conclusive proof thereof.

     [ ] UNCOMMITTED FACILITY. Borrower acknowledges and agrees that,
     notwithstanding any provisions of this Note or any other documents executed
     in connection with this Note, Bank has no obligation to make any advance,
     and that all advances are at the sole discretion of Bank.

     [ ] OUT-OF-DEBT PERIOD. For a period of at least ________________
     consecutive days during [ ] each fiscal year, [ ] any consecutive 12-month
     period, Borrower shall fully pay down the balance of this Note, so that no
     amount of principal or interest and no other obligation under this Note
     remains outstanding.

6.   AUTOMATIC PAYMENT.

[X] Borrower has elected to authorize Bank to effect payment of sums due under
this Note by means of debiting Borrower's account number 000658763107. This
authorization shall not affect the obligation of Borrower to pay such sums when
due, without notice, if there are insufficient funds in such account to make
such payment in full on the due date thereof, or if Bank fails to debit the
account.

7.   WAIVERS, CONSENTS AND COVENANTS. Borrower, any indorser or guarantor
hereof, or any other party hereto (individually an "Obligor" and collectively
"Obligors") and each of them jointly and severally: (a) waive presentment,
demand, protest, notice of demand, notice of intent to accelerate, notice of
acceleration of maturity, notice of protest, notice of nonpayment, notice of
dishonor, and any other notice required to be given under the law to any Obligor
in connection with the delivery, acceptance, performance, default or enforcement
of this Note, any indorsement or guaranty of this Note, or any other documents
executed in connection with this Note or any other note or other loan documents
now or hereafter executed in connection with any obligation of Borrower to Bank
(the "Loan Documents"); (b) consent to all delays, extensions, renewals or other
modifications of this Note or the Loan Documents, or waivers of any term hereof
or of the Loan Documents, or release or discharge by Bank of any of Obligors, or
release, substitution or exchange of any security for the payment hereof, or the
failure to act on the part of Bank, or any indulgence shown by Bank (without
notice to or further assent from any of Obligors), and agree that no such
action, failure to act or failure to exercise any right or remedy by Bank shall
in any way affect or impair the obligations of any Obligors or be construed as a
waiver by Bank of, or otherwise affect, any of Bank's rights under this Note,
under any indorsement or guaranty of this Note or under any of the Loan
Documents; and (c) agree to pay, on demand, all costs and expenses of collection
or defense of this Note or of any indorsement or guaranty hereof and/or the
enforcement or defense of Bank's rights with respect to, or the administration,
supervision, preservation, or protection of, or realization upon, any property
securing payment hereof, including, without limitation, reasonable attorney's
fees, including fees related to any suit, mediation or arbitration proceeding,
out of court payment agreement, trial, appeal, bankruptcy proceedings or other
proceeding, in such amount as may be determined reasonable by any arbitrator or
court, whichever is applicable.

8.   PREPAYMENTS. Prepayments may be made in whole or in part at any time on any
loan. All prepayments of principal shall be applied in the inverse order of
maturity, or in such other order as Bank shall determine in its sole discretion.

9.   DELINQUENCY CHARGE. To the extent permitted by law, a delinquency charge
may be imposed in an amount not to exceed four percent (4%) of the unpaid
portion of any payment that is more than fifteen days late. Unless the terms of
this Note call for repayment of the entire balance of this Note (both principal
and interest) in a single payment and not for installments of interest or
principal and interest, the 4% delinquency charge may be imposed not only with
respect to regular installments of principal or interest or principal and
interest, but also with respect to any other payment in default under this Note
(other than a previous delinquency charge), including without limitation, a
single payment of principal due at the maturity of this Note. In the event any
installment, or portion thereof, is not paid in a timely manner, subsequent
payments will be applied first to the past due balance (which shall not include
any previous delinquency charges), specifically to the oldest maturing
installment, and a separate delinquency charge will be imposed for each payment
that becomes due until the default is cured.

10.  EVENTS OF DEFAULT. The following are events of default hereunder: (a)
subject to the tolling of any applicable cure period, the failure to pay or
perform any obligation, liability or indebtedness of any Obligor to Bank, or to
any affiliate or subsidiary of Bank of America Corporation, whether under this
Note or any Loan Documents, as and when due (whether upon demand, at maturity or
by acceleration); (b) subject to the tolling of any applicable cure period, the
failure to pay or perform any other obligation, liability or indebtedness of any
Obligor to any other party; (c) the death of any Obligor (if an individual); (d)
the resignation or withdrawal of any partner or a material owner/guarantor of
Borrower, as determined by Bank in its sole discretion; (e) the commencement of
a proceeding against any Obligor for dissolution or liquidation, the voluntary
or involuntary termination or dissolution of any Obligor or the merger or
consolidation of any Obligor with or into another entity; (f) the insolvency of,
the business failure of, the appointment of a custodian, trustee, liquidator or
receiver for or for any of the property of, the assignment for the benefit of
creditors by, or the filing of a petition under bankruptcy, insolvency or
debtor's relief law or the filing of a petition for any adjustment of
indebtedness, composition or extension by or against any Obligor; (g) the
determination by Bank that any representation or warranty made to Bank by any
Obligor in any Loan Documents or otherwise is or was, when it was made, untrue
or materially misleading; (h) the entry of a judgment against any Obligor which
Bank deems to be of a material nature, in Bank's sole discretion; (i) the
seizure or forfeiture of, or the issuance of any writ of possession, garnishment
or attachment, or any turnover order for any property of any Obligor; or (j) the
failure of Borrower's business to comply with any law or regulation controlling
its operation, the failure to comply with which would result in a material
adverse effect on Borrower.

11.  REMEDIES UPON DEFAULT. Whenever there is a default under this Note (a) the
entire balance outstanding hereunder and all other obligations of any Obligor to
Bank (however acquired or evidenced) shall, at the option of Bank, become
immediately due and payable and any obligation of Bank to permit further
borrowing under this Note shall immediately cease and terminate, and/or (b) to
the extent permitted by law, the Rate of interest on the unpaid principal shall
be increased to 4% per annum in excess of the rate previously applicable to the
balance of unpaid principal hereunder (the "Default Rate"). The provisions
herein for a Default Rate and a delinquency charge shall not be deemed to extend
the time for any payment hereunder or to constitute a "grace period" giving
Obligors a right to cure any default. At Bank's option, any accrued and unpaid
interest, fees or charges may, for purposes of computing and accruing interest
on a daily basis after the due date of this Note or any installment thereof, be
deemed to be a part of the principal balance, and interest shall accrue on a
daily compounded basis after such date at the Default Rate provided in this Note
until the entire outstanding balance of principal and interest is paid in full.
Upon a default under this Note, Bank is hereby authorized at any time, at its
option and without notice or demand to set off and charge against any deposit
accounts of any Obligor (as well as any money, instruments, securities,
documents, chattel paper, credits, claims, demands, income and any other
property, rights and interests of any Obligor), which at any time shall come
into the possession or custody or under the control of Bank or any of its
agents, affiliates or correspondents, any and all obligations due hereunder.
Additionally, Bank shall have all rights and remedies available under each of
the Loan Documents, as well as all rights and remedies available at law or in
equity.

12.  NON-WAIVER. The failure at any time of Bank to exercise any of its options
or any other rights hereunder shall not constitute a waiver thereof, nor shall
it be a bar to the exercise of any of its options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. The acceptance by Bank of any
partial payment shall not constitute a waiver of any default or of any of Bank's
rights under this Note. No waiver of any of its rights hereunder, and no
modification or amendment of this Note, shall be deemed to be made by Bank
unless the same shall be in writing, duly signed on behalf of Bank; each such
waiver shall apply only with respect to the specific instance involved, and
shall in no way impair the rights of Bank or the obligations of Obligors to Bank
in any other respect at any other time.

Note or any Loan Documents, Obligors, and each of them, irrevocably consent to
and confer personal jurisdiction on the courts of the State of North Carolina or
the United States located within the State of North Carolina and expressly waive
any objections as to venue in any such courts. Nothing contained herein shall,
however, prevent Bank from bringing any action or exercising any rights within
any other state or jurisdiction or from obtaining personal jurisdiction by any
other means available under applicable law.

14.  PARTIAL INVALIDITY. The unenforceability or invalidity of any provision of
this Note shall not affect the enforceability or validity of any other provision
herein and the invalidity or unenforceability of any provision of this Note or
of the Loan Documents to any person or circumstance shall not affect the
enforceability or validity of such provision as it may apply to other persons or
circumstances.

15.  BINDING EFFECT. This Note shall be binding upon and inure to the benefit of
Borrower, Obligors and Bank and their respective successors, assigns, heirs and
personal representatives, provided, however, that no obligations of Borrower or
Obligors hereunder can be assigned without prior written consent of Bank.

16.  CONTROLLING DOCUMENT. To the extent that this Note conflicts with or is in
any way incompatible with any other document related specifically to the loan
evidenced by this Note, this Note shall control over any other such document,
and if this Note does not address an issue, then each other such document shall
control to the extent that it deals most specifically with an issue.

AFTER THE PENDENCY OF ANY ARBITRATION PROCEEDING BROUGHT PURSUANT TO THIS
INSTRUMENT, AGREEMENT OR DOCUMENT. NEITHER THIS EXERCISE OF SELF HELP REMEDIES
