All of the terms, conditions and covenants of the above described agreements
(the "Agreements") are expressly made a part of this Note by reference in the
same manner and with the same effect as if set forth herein at length and any
holder of this Note is entitled to the benefits of and remedies provided in the
Agreements and any other agreements by and between the undersigned and the Bank.

      No delay or omission on the part of the holder in exercising any right
hereunder shall operate as a waiver of such right or of any other right of such
holder, nor shall any delay, omission or waiver on any one occasion be deemed a
bar to or waiver of the same or of any other right on any future occasion. Every
one of the undersigned and every endorser or guarantor of this note regardless
of the time, order or place of signing waives presentment, demand, protest and
notices of every kind and assents to any one or more extensions or postponements
of the time of payment or any other indulgences, to any substitutions, exchanges
or releases of collateral if at any time there be available to the holder
collateral for this note, and to the additions or releases of any other parties
or persons primarily or secondarily liable.

      The failure to pay any part of the principal or interest when due on this
Note or to fully perform any covenant, obligation or warranty on this or on any
other liability to the Bank by any one or more of the undersigned, by any
affiliate of the undersigned (as defined in 11USC Section (101) (2)), or by any
guarantor or surety of this Note (said affiliate, guarantor, and surety are
herein called Obligor; or if any financial statement or other representation
made to the Bank by any of the undersigned or any Obligor shall be found to be
materially incorrect or incomplete; or in the event the default pursuant to any
of the Agreements or any other obligation of any of the undersigned or any
Obligor in favor of the Bank; or in the event the Bank demands that the
undersigned secure or provide additional security for its obligations under this
Note and security deemed adequate and sufficient by the Bank is not given when
demanded; or in the event one or more of the undersigned or any Obligor shall
die, terminate its existence, allow the appointment of a receiver for any part
of its property, make an assignment for the benefit of creditors, or where a
proceeding under bankruptcy or insolvency laws is initiated by or against any of
the undersigned or any Obligor; or in the event the Bank should otherwise deem
itself, its security interest, or any collateral unsafe or insecure; or should
the Bank in good faith believe that the prospect of payment or other performance
is impaired; or if there is an attachment, execution, or other judicial seizure
of all or any portion of the Borrower's or any Obligor's assets, including an
action or proceeding to seize any funds on deposit with the Bank, and such
seizure is not discharged within 20 days; or if final judgment for the payment
of money shall be rendered against the Borrower or any Obligor which is not
covered by insurance and shall remain undischarged for a period of 30 days
unless such judgment or execution thereon is effectively stayed; or the
termination of any guaranty agreement given in connection with this Note, then
any one of the same shall be a material default hereunder and this Note and
other debts due the Bank by any one or more of undersigned shall immediately
become due and payable without notice, at the option of the Bank. From and after
any event of default hereunder, interest shall accrue on the sum of the
principal balance and accrued interest then outstanding at the variable rate
equal to the Bank's Prime Rate plus 5% per annum ("Default Rate"), provided that
such rate shall not exceed at any time the highest rate of interest permitted by
the laws of the State of Georgia; and further provided that such rate shall
apply after judgement, in the event of any default, the then remaining unpaid
principal amount and accrued but unpaid interest then outstanding shall bear
interest at the Default Rate called for hereunder until such principal and
interest have been paid in full. In addition, upon default, the Bank may pursue
its full legal remedies at law or equity, and the balance due hereunder may be
charged against any obligation of the Bank to any party including any Obligor.
Bank shall not be obligated to accept any check, money order, or other payment
instrument marked "payment in full" on any disputed amount due hereunder, and
Bank expressly reserves the right to reject all such payment instruments.
Borrower agrees that tender of its check or other payment instrument so marked
will not satisfy or discharge its obligation under this Note, disputed or
otherwise, even if such check or payment instrument is inadvertently processed
by Bank unless in fact such payment is in fact sufficient to pay the amount due
hereunder.

      The term "Prime Rate," if used herein, means the rate of interest per
annum announced by the Bank from time to time and adopted as its Prime Rate.
Bank lends at rates above and below the Prime Rate, and the Prime Rate is one of
several rate indexes employed by the Bank when extending credit. Any change in
the interest rate resulting from a change in the Bank's Prime Rate shall become
effective as of the opening of business on the effective date of the change. If
this Note is placed with an attorney for collection, the undersigned agrees to
pay, in addition to principal and interest, all costs of collection and
reasonable attorneys' fees. All obligations of the undersigned and of any
Obligor shall bind his heirs, executors, administrators, successors, and/or
assigns. Use of the masculine pronoun herein shall include the feminine and the
neuter, and also the plural. If more than one party shall execute this Note, the
term "undersigned" as used herein shall mean all the parties signing this Note
and each of them, and all such parties shall be jointly and severally obligated
hereunder. Wherever possible, each



<PAGE>
provision of this Note shall be interpreted in such a manner to be effective and
valid under applicable law, but if any provision of this Note shall be
prohibited by or invalid under such law, such provision shall be ineffective but
only to the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Note. All of the
undersigned hereby waive all exemptions and homestead laws. The proceeds of the
loan evidenced by this Note may be paid to any one or more of the undersigned.

      From time to time, at the Bank's option, the maturity date of this Note
may be extended, or this Note maybe renewed in whole or in part, or a new note
of different form may be substituted for this Note, or the rate of interest may
be modified, or changes may be made in consideration of loan extensions, and the
holder hereof, from time to time may waive or surrender, either in whole or in
part any rights, guarantees, secured interest, or loans, given for the benefit
of the holder in connection with the payment and the securing payment of this
Note; but no such occurrence shall in any manner affect, limit, modify, or
otherwise impair any rights, guaranties or security of the holder not
specifically waived, released, or surrendered in writing, nor shall the
undersigned makers, or any guarantor, endorser, or any person who is or might be
liable hereon, either primarily or contigently, be released from such event. The
holder hereof, from time to time, shall have the unlimited right to release any
person who might be liable hereon, and such release shall not affect or
discharge the liability of any other person who is or might be liable hereon. No
waivers and modifications shall be valid unless in writing and signed by the
Bank. The Bank may, at its option, charge any fees for the modification,
renewal, extension, or amendment of any of the terms of the note permitted by
applicable law. In case of a conflict between the terms of this Note and the
Loan Agreement, or the Commitment Letter issued in connection herewith, the
priority of controlling terms shall be first this Note, then the Loan Agreement,
and then the Commitment Letter. This Note shall be governed by and construed in
accordance with the laws of Georgia in connection with any foreclosure or
enforcement proceeding undertaken in connection with the Borrower's property
situated in Georgia. Time is of the essence of this instrument.

Borrower agrees that the only interest charge is the interest actually stated in
this Note, and that any loan or origination fee shall be deemed charges other
than interest, which charges are fully earned and non-refundable. It is further
agreed that any late charges are not a charge for the use of money but are
imposed to compensate Bank for some of the administrative services, cost and
losses associated with any deliquency or default under this Note, and said
charges shall be fully earned and non-refundable when accrued. All other charges
imposed by Bank upon Borrower in connection with this Note and the loan
including without limitation, any commitment less, loan fees, facility fees,
origination fees, discount points, default and late charges, prepayment fees,
statutory attorney's fees and reimbursements for costs and expenses paid by Bank
to third parties or for damages incurred by Bank are and shall be deemed to be
charges made to compensate Bank for underwriting and administrative services and
costs, other services, and costs or losses incurred and to be incurred by Bank
in connection with this Note and the loan shall under no circumstances be deemed
to be charges for the use of money. All such charges shall be fully earned and
non-refundable when due. This paragraph is executed for the purpose of
clarifying the status of charges of the Loan for purpose of O.C.G.A. Sec.
7-4-2(a) and (a)(3).

It is the intention of Bank and Borrower to conform strictly to the usury laws
now or hereafter in effect, and any interest payable hereunder shall be subject
to reduction to the amount in excess of the maximum non-usurious amount allowed
under applicable usury laws now or hereafter construed by courts having
jurisdiction over such matters. If the maturity of this Note is accelerated by
reason of any provision of this Note or by reason of voluntary prepayment by the
undersigned, or otherwise, then earned interest may never include more than the
maximum amount permitted by law, computed from the date of each advance of the
loan proceeds hereunder until payment, and any interest in excess of the maximum
amount permitted by law shall be cancelled automatically and, if paid, shall at
the option of Bank, if allowed by applicable law, either be rebated to Borrower
or credited on the principal amount of this Note, or if all principal has
heretofor been repaid, then the excess shall be rebated to Borrower.

--------------------------------------------------------------------------------

                      CREDIT LIFE AND DISABILITY INSURANCE

Subject to certain underwriting criteria and limitations, INDIVIDUAL BORROWERS
AND ADDITIONAL CO-MAKERS HAVE THE RIGHT TO REQUEST CREDIT LIFE AND DISABILITY
INSURANCE PROTECTION FOR THIS LOAN. One or two Borrowers/Co-makers may be
covered by BB&T Credit Life Insurance and one Borrower/Co-maker may be covered
by BB&T Credit Disability Insurance. However, the purchase of credit life and
credit disability insurance from the Bank is not a condition of obtaining this

      described below and promise to pay the premium of such insurance coverage.
      I understand that I may cancel this credit insurance at any time. I

All of the terms, conditions and covenants of the above described agreements
(the "Agreements") are expressly made a part of this Note by reference in the
same manner and with the same effect as if set forth herein at length and any
holder of this Note is entitled to the benefits of and remedies provided in the
Agreements and any other agreements by and between the undersigned and the Bank.

      No delay or omission on the part of the holder in exercising any right
hereunder shall operate as a waiver of such right or of any other right of such
holder, nor shall any delay, omission or waiver on any one occasion be deemed a
bar to or waiver of the same or of any other right on any future occasion. Every
one of the undersigned and every endorser or guarantor of this note regardless
of the time, order or place of signing waives presentment, demand, protest and
notices of every kind and assents to any one or more extensions or postponements
of the time of payment or any other indulgences, to any substitutions, exchanges
or releases or collateral if at any time there be available to the holder
collateral for this note, and to the additions or releases of any other parties
or persons primarily or secondarily liable.

        The failure to pay any part of the principal or interest when due on
this Note or to fully perform any covenant, obligation or warranty on this or on
any other liability to the Bank by any one or more of the undersigned, by any
affiliate of the undersigned (as defined in 11USC Section (101) (21)), or by any
guarantor or surety of this Note (said affiliate, guarantor, and surety are
herein called Obligor); or if any financial statement or other representation
made to the Bank by any of the undersigned or any Obligor shall be found to be
materially incorrect or incomplete; or in the event the default pursuant to any
of the Agreements or any other obligation of any of the undersigned or any
Obligor in favor of the Bank; or in the event the Bank demands that the
undersigned secure or provide additional security for its obligations under this
Note and security deemed adequate and sufficient by the Bank is not given when
demanded; or in the event one or more of the undersigned or any Obligor shall
die, terminate its existence, allow the appointment of a receiver for any part
of its property, make an assessment for the benefit of creditors, or where a
proceeding under bankruptcy or insolvency laws is initiated by or against any of
the undersigned or any Obligor; or in the event the Bank should otherwise deem
itself, its security interest, or any collateral unsafe or insecure; or should
the Bank in good faith believe that the prospect of payment or other performance
is impaired; or if there is an attachment, execution, or other judicial seizure
of all or any portion of the Borrower's or any Obligor's assets, including an
action or proceeding to seize any funds on deposit with the Bank, and such
seizure is not discharged within 20 days; or if final judgment for the payment
of money shall be rendered against the Borrower or any Obligor which is not
covered by insurance and shall remain undischarged for a period of 30 days
unless such judgment or execution thereon is effectively stayed; or the
termination of any guaranty agreement given in connection with this Note, then
any one of the same shall be a material default hereunder and this Note and
other debts due the bank by any one or more of undersigned shall immediately
become due and payable without notice, at the option of the Bank. >From and
after any event of default hereunder, interest shall accrue on the sum of the
principal balance and accrued interest then outstanding at the variable rate
equal to the Bank's Prime Rate plus 5% per annum ("Default Rate"), provided that
such rate shall not exceed at any time the highest rate of interest permitted by
the laws of the State of Georgia; and further provided that such rate shall
apply after judgement. In the event of any default, the then remaining unpaid
principal amount and accrued but unpaid interest then outstanding shall bear
interest at the Default Rate called for hereunder until such principal and
interest have been paid in full. In addition, upon default, the Bank may pursue
its full legal remedies at law or equity, and the balance due hereunder may be
charged against any obligation of the Bank to any party including any Obligor.
Bank shall not be obligated to accept any check, money order, or other payment
instrument marked "payment in full" on any disputed amount due hereunder, and
Bank expressly reserves the right to reject all such payment instruments.
Borrower agrees that tender of its check or other payment instrument so marked
will not satisfy or discharge its obligation under this Note, disputed or
otherwise, even if such check or payment instrument is inadvertently processed
by Bank unless in fact such payment is in fact sufficient to pay the amount due
hereunder.

      The term "Prime Rate," if use herein, means the rate of interest per annum
announced by the Bank from time to time and adopted as its Prime Rate. Bank
lends at rates above and below the Prime Rate, and the Prime Rate is one of
several rate indexes employed by the Bank when extending credit. Any change in
the interest rate resulting from a change in the Bank's Prime Rate shall become
effective as of the opening of business on the effective date of the change. If
this Note is placed with an attorney for collection, the undersigned agrees to
pay, in addition to principal and interest, all costs of collection and
reasonable attorneys' fees. All obligations of the undersigned and of any
Obligor shall bind his heirs, executors administrators, successors, and/or
assigns. Use of the masculine pronoun herein shall include the feminine and the
neuter, and also the plural. If more than one party shall execute this Note, the
term "undersigned" as used herein shall mean all the parties signing this Note
and each of them, and all such parties shall be jointly and severally obligated
hereunder. Wherever possible, each

<PAGE>

provision of this Note shall be interpreted in such a manner to be effective and
valid under applicable law, but if any provision of this Note shall be
prohibited by or invalid under such law, such provision shall be ineffective but
only to the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Note. All of the
undersigned hereby waive all exemptions and homestead laws. The proceeds of the
loan evidenced by this Note may be paid to any one or more of the undersigned.

      From time to time, at the Bank's option, the maturity date of this Note
may be extended, or this Note may be renewed in whole or in part, or a new note
of different form any be substituted for this Note, or the rate of interest may
be modified, or changes may be made in consideration of loan extensions, and the
holder hereof, from time to time may waive or surrender, either in whole or in
part any rights, guaranties, secured interest, or liens, given for the benefit
of the holder in connection with the payment and the securing the payment of
this Note; but no such occurrence shall in any manner effect, limit, modify, or
otherwise impair any rights, guaranties or security of the holder not
specifically waived, released, or surrendered in writing, nor shall the
undersigned makers, or any guarantor, endorser, or any person who is or might be
liable hereon, either primarily or contingently, be released from such event.
The holder hereof, from time to time, shall have the unlimited right to release
any person who might be liable hereon, and such release shall not affect or
discharge the liability of any other person who is or might be liable hereon. No
waivers and modifications shall be valid unless in writing and signed by the
Bank. The Bank may, at its option, charge any fees for the modification,
renewal, extension, or amendment of any of the terms of the Note permitted by
applicable law. In case of a conflict between the terms of this Note and the
Loan Agreement or Commitment Letter issued in connection herewith, the priority
of controlling terms shall be first this Note, then the Loan Agreement, and then
the Commitment Letter. This Note shall be governed by and construed in
accordance with the laws of Georgia in connection with any foreclosure or
enforcement proceeding undertaken in connection with the Borrower's property
situated in Georgia. Time is of the essence of this instrument.

Borrower agrees that the only interest charge is the interest actually stated in
this Note, and that any loan or origination fee shall be deemed charges rather
than interest, which charges are fully earned and non-refundable. It is further
agreed that any late charges are not a charge for the use of money but are
imposed to compensate Bank for some of the administrative services, costs and
losses associated with any delinquency or default under this Note, and said
charges shall be fully earned and non-refundable when accrued. All other charges
imposed by Bank upon Borrower in connection with this Note and the loan
including without limitation, any commitment fees, loan fees, facility fees,
origination fees, discount points, default and late charges, prepayment fees,
statutory attorney's fees and reimbursements for costs and expenses paid by Bank
to third parties or for damages incurred by Bank are and shall be deemed to be
charges made to compensate Bank for underwriting and administrative services and
costs, other services, and costs or losses incurred and to be incurred by Bank
in connection with this Note and the loan shall under no circumstances be deemed
to be charges for the use of money. All such charges shall be fully earned and
non-refundable when due. This paragraph is executed for the purpose of
clarifying the status of charges of the Loan for purpose of O.C.G.A. Sec.
7-4.2(a) and (a)(3).

It is the intention of Bank and Borrower to conform strictly to the usury laws
now or hereafter in effect, and any interest payable hereunder shall be subject
to reduction to the amount in excess of the maximum non-usurious amount allowed
under applicable usury laws now or hereafter construed by courts having
jurisdiction over such matters. If the maturity of this Note is accelerated by
reason of any provision of this Note or by reason of voluntary prepayment by the
undersigned, or otherwise, then earned interest may never include more than the
maximum amount permitted by law, computed from the date of each advance of the
loan proceeds hereunder until payment, and any interest in excess of the maximum
amount permitted by law shall be cancelled automatically and, if paid, shall at
the option of Bank, if allowed by a applicable law, either be rebated to
Borrower or credited on the principal amount of this Note, or if all principal
has heretofor been repaid, then the excess shall be rebated to Borrower.

--------------------------------------------------------------------------------

                      CREDIT LIFE AND DISABILITY INSURANCE

Subject to certain underwriting criteria and limitations, INDIVIDUAL BORROWERS
AND ADDITIONAL CO-MAKERS HAVE THE RIGHT TO REQUEST CREDIT LIFE AND DISABILITY
INSURANCE PROTECTION FOR THIS LOAN. One or two Borrowers/Co-makers may be
covered by BB&T Credit Life Insurance and one Borrower/Co-maker may be covered
by BB&T Credit Disability Insurance. However, the purchase of credit life and
credit disability insurance from the Bank is not a condition of obtaining this
loan.


     I, the undersigned, desire the credit insurance with the cost and terms
     described below and promise to pay the premium of such insurance coverage.
     I understand that I may cancel this credit insurance at any time. I
     represent that, to the best of my knowledge, I am in good health and am
     insurable.
