</TABLE>

PROMISE TO PAY. GTS / HDD, INC. ("BORROWER") PROMISES TO PAY TO REGIONS BANK
("LENDER"). OR ORDER, IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA. THE
PRINCIPAL AMOUNT OF TWO HUNDRED FIFTY THOUSAND & 00/100 DOLLARS ($250,000.00),
TOGETHER WITH INTEREST ON THE UNPAID PRINCIPAL BALANCE FROM DECEMBER 28. 2000,
UNTIL PAID IN FULL. THE INTEREST RATE WILL NOT INCREASE ABOVE 11.000%.
PAYMENT. Subject to any payment changes resulting from changes in the Index,
Borrower will pay this loan in 35 payments of $8,007.78 each payment and an
irregular last payment estimated at $8,007.76. Borrower's first payment is due
January 28, 2001, and a0 subsequent payments are due on the same day of each
month after that. Borrower's final payment will be due on December 28. 2003, and
will be for all principal and all accrued interest not yet paid. Payments
include principal and interest. Interest on this Note is computed on a 365!365
simple interest basis: that is, by applying the ratio of the annual interest
rate over the number of days in a year (366 during leap years), multiplied by
the outstanding principal balance, multiplied by the actual number of days the
principal balance is outstanding. Borrower will pay Lender at Lender's address
shown above or at such other place as Lender may designate in writing. Unless
otherwise agreed or required by applicable law, payments will be applied first
to accrued unpaid interest, then to principal, and any remaining amount to any
unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rata on this Note is subject to change from
time to time based on changes in an index which is the Regions Financial Corp.
Commercial Base Rate (the "Index"). The Index is not necessarily the lowest rate
charged by Lender on its loans and is set by Lender in its sole discretion. If
the Index becomes unavailable during the term of this loan, Lender may designate
a substitute index after notifying Borrower. Lender will tell Borrower the
current Index rate upon Borrower's request. Borrower understands that Lender may
make loans based on other rates as well. The interest rate change will not occur
more often than each month. The Index currently is 9.500% per annum. The
interest rate to be applied to the unpaid principal balance of this Note will be
at a rate equal to the Index, adjusted if necessary for the maximum rate
limitation described below, resulting in an Initial rate of 9.500% per annum.
Notwithstanding any other provision of this Note, the variable interest rate or
rates provided for in this Note will be subject to the following maximum rate.
NOTICE: Under no circumstances will the interest rate on this Note be more than
the lesser of 11.000% per annum or the maximum rate allowed by applicable law.
Whenever increases occur in the interest rate, lender, at its option, may do one
or more of the following: (al increase Borrower's payments to ensure Borrower's
loan will pay off by its original final maturity date, (b) increase Borrower's
payments to cover accruing interest, (c) increase the number of Borrower's
payments, and (d) continue Borrower's payments at the same amount and increase
Borrower's final payment.

PREPAYMENT. Borrower may pay ail or a portion of the amount owed earlier than it
is due. Early payments will not, unless agreed to by Lender in writing, relieve
Borrower of Borrower's obligation to continue to make payments under the payment
schedule. Rather, they will reduce the principal balance due and may result in
Borrower making fewer payments.

LATE CHARGE. If a payment is 10 days or more late, Borrower will be charged
$25.00.

DEFAULT. Borrower will be in default if any of the following happens: (al
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Any representation or statement made or furnished to Lender
by Borrower or on Borrower's behalf is false or misleading in any material
respect either now or at the time made or furnished. (d) Borrower becomes
insolvent, a receiver Is appointed for any part of Borrower's property, Borrower
makes an assignment for the benefit of creditors, or any proceeding is commenced
either by Borrower or against Borrower under any bankruptcy or insolvency laws.
(el Any creditor tries to take any of Borrower's property on or in which Lender
has a lien or security interest. This includes a garnishment of any of
Borrower's accounts with lender, lf) Any guarantor dies or any of the other
events described in this default section occurs with respect to any guarantor of
this Note. (g) A material adverse change occurs in Borrower's financial
condition, or Lender believes the prospect of payment or performance of the

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
