THOUSAND Dollars, or such lesser amount as may be outstanding and unpaid
hereunder, together with Interest on each advance made under this note at the
rate and on the date(s) provided below from the date each advance hereunder is
made to the earlier of the date such advance is repaid or maturity of this note,
and with interest on the unpaid principal balance after maturity at the rate
which is 2 percent per annum in excess of the rate stated below or the maximum
rate allowed by law, whichever is less, from maturity until said indebtedness is
paid in full.

Interest will accrue on the above-stated principal sum daily at the rate per
annum which is equal to either (a) the Prime Rate minus 0.25% or (b) LIBOR plus
0.25%. For purposes of this Revolving Note, the term "Prime Rate" shall mean the
higher of (x) the rate which Bank publicly announces from time to time to be its
prime lending rate, as in effect from time to time, and (y) the Federal Funds
Rate, as in effect from time to time, plus one-half of one percent (0.50%) per
annum. Bank's prime lending rate is a reference rate and does not necessarily
represent the lowest or best rate charged to customers; Bank may make commercial
loans or other loans at rates of interest at, above or below Bank's prime
lending rate. Each change in any interest rate provided for herein based upon
the Base Rate resulting from a change in the Base Rate shall take effect as of
the date of such change in the Base Rate. "Federal Funds Rate" shall mean, for
any period, a fluctuating interest rate per annum (rounded upward, if necessary,
to the nearest 1/100 of 1%) equal for each day during such period to the
weighted average of the rates on overnight Federal funds transactions with
members of the Federal Reserve System arranged by Federal funds brokers on such
day, as published by the Federal Reserve Bank of New York on the Business Day
next succeeding such day, provided that (i) if such day is not a Business Day,
the Federal Funds Rate for such day shall be such rate on such transactions on
the next preceding Business Day as so published on the next succeeding Business
Day, and (ii) if no such rate is published on such next succeeding Business Day,
the Federal Funds Rate for such day shall be the average rate quoted to Bank on
such day on such transactions by three Federal funds brokers of recognized
standings selected by Bank. "LIBOR" shall mean the offered rate per annum for
                             -----
deposits in U.S. Dollars for a period comparable to the Interest Period and in

Telerate Page 3750 as of 11:00 A.M. (London, England time) on the day that is
two Business Days prior to the first day of the Interest Period; provided,
                                                                 --------
however, that if two or more of such rates appear on Telerate Page 3750, the
-------
rate shall be the arithmetical mean of such rates, or if the foregoing rate is
unavailable from Telerate Page 3750 for any reason, then such rate shall be the
arithmetic average of rates offered to Bank by not less than two major banks in
New York, New York at approximately 10:00 a.m. (Atlanta, Georgia time) on the
day that is two Business Days prior to the first day of the Interest Period for
deposits in U.S. Dollars in the London interbank market for a period comparable
to the Interest Period and in an amount comparable to the principal amount of
such Advance; in any such case rounded upwards, if necessary, to the next higher
1/100 of 1.0%, if the rate is not such a multiple. "Interest Period" shall mean
thirty (30) days.

Obligors may prepay this note in full at any time without penalty.

The Obligors promise to pay the above-stated principal sum in full:

 [X] on June 24, 2000. [_] on demand.  [_] on demand, but if no demand is made,

                                       then on ____________, 19__.

The Obligors promise to pay accrued interest on the unpaid balance of the
principal sum:

 [X] monthly on the 1st day of each month beginning July 1, 1999, and at
 maturity.

 [_] quarterly beginning on ________________, 19__, on the same day every three
 months thereafter, and at maturity.

Until the earlier of maturity of this note, or the occurrence of any event
giving Bank the right to accelerate maturity of the note as provided below, or
written or oral notice to any Obligor of Bank's election to terminate the line
of credit (which notice Bank may give at its discretion), the undersigned may
borrow hereunder, prepay the principal sum in whole or in part without penalty,
and reborrow hereunder, so long as the aggregate unpaid principal balance of
such borrowings does not exceed the principal amount of this note at any time.
Bank may require that borrowings be made only upon at least one banking day's
written notice to Bank. For the privilege of having such credit available, the
undersigned agrees to pay Bank a commitment fee of 0 percent per annum on the
unused portion of the principal sum of this note, such fee to be calculated and
payble as follows: _____________________________________________________________
________________________________________________________________________________

Interest on the principal sum will be calculated at the rate set forth above on
the basis of a 360-day year and the actual number of days clapsed by multiplying
the principal sum by the per annum rate set forth above, multiplying the product
thereof by the actual number of days elapsed, and dividing the product so
obtained by 360. Obligors acknowledge that the rate of interest payable under
this Note, computed on the basis of a 365-day year and expressed in simple
interest terms as of the date hereof, is 7.79 percent per annum. The interest
rate payable hereunder may be calculated in simple interest terms per annum (on
the basis of a 366-day year) on any date by taking the sum of (a) the Base Rate
in effect on such date, plus (b) NA percent and multiplying such sum by a
                                 --
fraction, the numerator of which is 365 and the denominator of which is 360.

     If payment of the principal sum of this note is late 10 days or more, In
addition to interest after maturity as provided above, Obligors agree to pay a
late charge equal to one-half of one percent (1/2%) of the amount of the payment
which is late, subject to a minimum late charge of $50 and a maximum late charge
of $250.00.

     This note is secured by every security agreement, pledge, assignment, stock

               Additional Terms and Conditions of Revolving Note
                      (Terms Continued from Reverse Side)


     As additional Collateral for the payment of all Obligations, the Obligors
jointly and severally transfer, assign, pledge, and set over to the Holder, and
grant the Holder a continuing lien upon and security interest in, any and all
property of each Obligor that for any purpose, whether in trust for any Obligor
or for custody, pledge, collection or otherwise, is now or hereafter in the
actual or constructive possession of, or in transit to, the Holder in any
capacity, its correspondents or agents, and also a continuing lien upon and
right of set-off against all deposits and credits of each Obligor with, and all
claims of each Obligor against, the Holder now or at any time hereafter
existing. The Holder is hereby authorized, at any time or times and without
prior notice, to apply such property, deposits, credits, and claims, in whole or
in part and in such order as the Holder may elect, to the payment of, or as a
reserve against, one or more of the Obligations, whether other Collateral
therefor is deemed adequate or not. All such property, deposits, credits and
claims of the Obligors are included in the term Collateral, and the Holder shall
have (unless prohibited by law) the same rights with respect to such Collateral
as it has with respect to other Collateral.

     Without the necessity for notice to or consent of any Obligor, the Holder
may exercise any rights of any of the Obligors with respect to any Collateral,
including without limitation thereto the following rights: (1) to record or
register in, or otherwise transfer into, the name of the Holder or its nominee
any part of the Collateral, without disclosing that the Holder's interest is
that of a secured party; (2) to pledge or otherwise transfer any or all of the
Obligations and/or Collateral, whereupon any pledgee or transferee shall have
all the rights of the Holder hereunder, and the Holder shall thereafter be fully
discharged and relieved from all responsibility and liability for the Collateral
so transferred but shall retain all rights and powers hereunder as to all
Collateral not so transferred; (3) to take possession of any Collateral and to
receive any proceeds of and dividends and income on any Collateral, including
money, and to hold the same as Collateral or apply the same to any of the
Obligations, the manner, order and extent of such application to be in the sole
discretion of the Holder; (4) to exercise any and all rights of voting,
conversion, exchange, subscription or other rights or options pertaining to any
Collateral; and (5) to liquidate, demand, sue for, collect compromise, receive
and receipt for the cash or surrender value of any Collateral. If for any reason
whatsoever the Collateral shall cease to be satisfactory to the Holder, the
Obligors shall upon demand deposit with the Holder additional Collateral
satisfactory to the Holder. Surrender of this note, upon payment or otherwise,
shall not affect the right of the Holder to retain the Collateral as security
for other Obligations. Upon default, the Obligors agree to assemble the
Collateral and make it available to Holder at such places as the Holder shall
designate.

     The Holder shall be deemed to have exercised reasonable care in the custody
and preservation of any of the Collateral which is in its possession if it takes
such reasonable actions for that purpose as the pledgor of such Collateral shall
request in writing, but the Holder shall have sole power to determine whether
such actions are reasonable. Any omission to do any act not requested by the
pledgor shall not be deemed a failure to exercise reasonable care. The Obligors
shall be responsible for the preservation of the Collateral and shall take all
steps to preserve rights against prior parties. The Holder shall have the right
to, but shall not be obligated to, preserve rights against prior parties. The
Holder shall not be liable for, and no Obligor, indorser, or guarantor shall be
discharged to any extent on account of, any failure to realize upon, or to
exercise any right or power with respect to, any of the Obligations or
Collateral, or for any delay in so doing.

     The Holder, without making any demands whatsoever, shall have the right to
sell all or any part of the Collateral, although the Obligations may be
contingent or unmatured, whenever the Holder considers such sale necessary for
its protection. Sale of the Collateral may be made, at any time and from time to
time, at any public or private sale, at the option of the Holder, without
advertisement or notice to any Obligor, except such notice as is required by law
and cannot be waived. The Holder may purchase the Collateral at any such sale
(unless prohibited by law) free from any equity of redemption and from all other
claims. After deducting all expenses, including legal expenses and attorney's
fees, for maintaining and selling the Collateral and collecting the proceeds of
sale, the Holder shall have the right to apply the remainder of said proceeds in
payment of, or as a reserve against, any of the Obligations, the manner, order
and extent of such application to be in the sole discretion of the Holder. To
the extent notice of any sale or other disposition of the Collateral is required
by law to be given to any Obligor, the requirement of reasonable notice shall be
met by sending such notice, as provided below, at lease ten (10) calendar days
before the time of sale or disposition. The Obligors shall remain liable to the
Holder for the payment of any deficiency, with interest at the rate provided
hereinabove. However, the Holder shall not be obligated to resort to any
Collateral but, at its election, may proceed to enforce any of the Obligations
in default against any or all of the Obligors.

     The Obligors understand that the Bank may enter into participation
agreements with participating banks whereby the Bank will sell undivided
interests in this note to such other banks. The Obligors consent that the Bank
may furnish information regarding the Obligors, including financial information,
to such banks from time to time and also to prospective participating banks in
order that such banks may make an informed decision whether to purchase a
participation in this note. The Obligors hereby grant to each such participating
bank, to the extent of its participation in this note, the right to set off
deposit accounts maintained by the Obligors, or any of them, with such bank,
against unpaid sums owed under this note. Upon written request from the Holder,
the Obligors agree to make each payment under this note directly to each such
participating bank in proportion to the participant's interest in this note as
set forth in such request from the Holder.

      If, at any time, the rate or amount of interest, late charge, attorneys'
fees or any other charge payable under this note shall exceed the maximum rate
or amount permitted by applicable law, then, for such time as such rate or
amount would be excessive, its application shall be suspended and there shall be
charge instead the maximum rate or amount permitted under such law, and any
excess interest or other charge paid by the Obligors or collected by the Holder
shall be refunded to the Obligors or credited against the principal sum of this
note, at the election of the Holder or as required by applicable law. Obligors
agree that the late charge provided in this note is a reasonable estimate of
probable additional unanticipated internal costs to the Holder of reporting and
accounting for the late payment, that such costs are difficult or impossible to
estimate accurately, and that the agreement to pay a late charge is a reasonable
liquidated damages provision.

     The Holder shall not by any act, delay, omission or otherwise be deemed to
have waived any of its rights or remedies, and no waiver of any kind shall be
valid, unless in writing and signed by the Holder. All rights and remedies of
the Holder under the terms of this note and under any statutes or rules of law
are cumulative and may be exercised successively or concurrently. The Obligors
jointly and severally agree that the Holder shall be entitled to all the rights
of a holder in due course of a negotiable instrument. This note shall be
governed by and construed in accordance with the substantive laws of the United
States and the state where the office of the Bank set forth above in the first
paragraph of this note is located, without regard to the rules of such stage
governing conflicts of law. Any provision of this note which may be
unenforceable or invalid under any law shall be ineffective to the extent of
such unenforceability or invalidity without affecting the enforceability or
validity of any other provision hereof. Any notice required to be given to any
person shall be deemed sufficient if delivered to such person or if mailed,
postage prepaid, to such person's address as it appears on this note or, if none
appears, to any address of such person in the Holder's files. The Holder shall
have the right to correct patent errors in this note.

     Time is of the essence of the payment and performance of this note.


EACH INDORSER OF THIS NOTE AGREES TO BE BOUND BY THE PROVISIONS PRINTED OR
OTHERWISE APPEARING ABOVE AND ON THE FACE OF THIS NOTE, INCLUDING THE PROVISION
FOR PAYMENT OF ATTORNEYS' FEES FOR COLLECTION.
