===============================================================================================================


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 Ten Million 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.

1.     RATE.  The Rate shall be the 90-day LIBOR (London Interbank Offering
Rate), plus 2 percent ("Applicable Margin"), per annum.  The "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 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.

The Rate of the Loan shall also be subject to adjustment based on the
Borrower's Leverage ratio as defined under the Financial Covenants in the Loan
Agreement.  The calculation and any change in the Applicable Margin shall take
place on the first day of the month immediately following receipt of financial
information for the preceding fiscal quarter.



                     Leverage Ratio                      Applicable Margin
                     --------------                      -----------------                 
                                                     
                      > than 1.0                        2.25 percent per annum

                      # to 1.0 but                      2.00 percent per annum
                      # to 0.60

                      < than 0.60                       1.75 percent per annum


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).

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.

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


NationsBank    Promissory Note       
                                 North Carolina [Commercial]--        2/96

NationsBank, N.A.

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.

       SINGLE PRINCIPAL PAYMENT.  Principal shall be paid in full in a single
payment on September 30, 1998.  Interest thereon shall be paid monthly,
commencing on April 30, 1998, and continuing on the same day of each successive
month thereafter, with a final payment of all unpaid interest at the stated
maturity of this Note.

5.     REVOLVING FEATURE.  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.

6.     AUTOMATIC PAYMENT.  Borrower has elected to authorize Bank to effect
payment of sums due under this Note by means of debiting Borrower's account
number _______________________________.  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.     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.

9.     EVENTS OF DEFAULT.  The following are events of default hereunder:  (a)
the failure to pay or perform any obligation, liability or indebtedness of any
Obligor to Bank, or to any affiliate or subsidiary of NationsBank Corporation,
whether under this Note or any  Loan Documents, as and when due (whether upon
demand, at maturity or by acceleration); (b) the death of any Obligor (if an
individual); (c) the resignation or withdrawal of any partner or a material
owner/guarantor of Borrower, as determined by Bank in  its sole discretion; (d)
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; (e) 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; (f) 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; (g) the failure of any Obligor to
timely deliver such financial statements, including tax returns, other
statements of condition or other information, as Bank shall request from time
to time; (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; (j) the determination by
Bank that a material adverse change has occurred in the financial condition of
any Obligor; or (k) the failure of Borrower's business to comply with any law
or regulation controlling its operation.

10.    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 at Bank's discretion up to the maximum rate allowed by law, or if
none, Prime plus 3% per annum (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.

11.    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.

12.    APPLICABLE LAW, VENUE AND JURISDICTION.  This Note and the rights and
obligations of Borrower and Bank shall be governed by and interpreted in
accordance with the law of the State of North Carolina.  In any litigation 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.

13.    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.

14.    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.

15.    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
