2.       LOAN AND TERMS OF PAYMENT

         2.1.     CREDIT EXTENSIONS. Borrower promises to pay to the order of
Bank, in lawful money of the United States of America, the aggregate unpaid
principal amount of all Credit Extensions made by Bank to Borrower hereunder.
Borrower shall also pay interest on the unpaid principal amount of such Advances
at rates in accordance with the terms hereof.

                  2.1.1.   REVOLVING LINE OF CREDIT.

                           (a)      Subject to and upon the terms and conditions
of this Agreement, Bank agrees to make Advances to Borrower in an aggregate
outstanding amount not to exceed the Borrowing Base minus the balance owing on
the Revolving Line of Credit. Subject to the terms and conditions of this
Agreement, amounts borrowed pursuant to this Section 2.1 may be repaid and
reborrowed at any time during the term of this Agreement.

                           (b)      Whenever Borrower desires an Advance,
Borrower will notify Bank by facsimile transmission or telephone no later than
3:00 p.m. Atlanta, Georgia time, on the Business Day that the Advance is to be
made. Each such notification shall be promptly confirmed by a Payment/Advance
Form in substantially the form of Exhibit B hereto. Bank is authorized to make
Advances under this Agreement, based upon instructions received from a
Responsible Officer or a designee of a Responsible Officer, or without
instructions if in Bank's discretion such Advances are necessary to meet
Obligations which have become due and remain unpaid. Bank shall be entitled to
rely on any telephonic notice given by a person who Bank reasonably believes to
be a Responsible Officer or a designee thereof, and Borrower shall indemnify and
hold Bank harmless for any damages or loss suffered by Bank as a result of such
reliance. Bank will credit the amount of Advances made under this Section 2.1 to
Borrower's deposit account.

                           The Revolving Line of Credit shall terminate on the
Revolving Line Maturity Date, at which time all Advances under this Section 2.1
and other amounts due under this Agreement (except as otherwise expressly
specified herein) shall be immediately due and payable.

         2.2.     OVERADVANCES. If, at any time or for any reason, the amount of
Obligations owed by Borrower to Bank pursuant to Section 2.1.1 of this Agreement
is greater than the Borrowing Base, Borrower shall immediately pay to Bank, in
cash, the amount of such excess.

         2.3.     INTEREST RATES, PAYMENTS, AND CALCULATIONS.

                  (a)      Interest Rate. Except as set forth in Section 2.3(b),
any Advances shall bear interest, on the average daily balance thereof, at a per
annum rate equal to the Prime Rate.

                  (b)      Default Rate. All Obligations shall bear interest,
from and after the occurrence of an Event of Default, at a rate equal to five
(5) percentage points above the interest rate applicable immediately prior to
the occurrence of the Event of Default.

                  (c)      Payments. Interest hereunder shall be due and payable
on each Payment Date. Borrower hereby authorizes Bank to debit any accounts with
Bank, including, without limitation, Account Number _______ for payments of
principal and interest due on the Obligations and any other amounts owing by
Borrower to Bank. Bank will notify Borrower of all debits which Bank has made
against Borrower's accounts. Any such debits against Borrower's accounts in no
way shall be deemed a set-off.

<PAGE>   9

                  (d)      Computation. In the event the Prime Rate is changed
from time to time hereafter, the applicable rate of interest hereunder shall be
increased or decreased effective as of 12:01 a.m. on the day the Prime Rate is
changed, by an amount equal to such change in the Prime Rate. All interest
chargeable under the Loan Documents shall be computed on the basis of a three
hundred sixty (360) day year for the actual number of days elapsed.

         2.4.     CREDITING PAYMENTS. Prior to the occurrence of an Event of
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrower specifies. After the
occurrence of an Event of Default, the receipt by Bank of any wire transfer of
funds, check, or other item of payment, whether directed to Borrower's deposit
account with Bank or to the Obligations or otherwise, shall be immediately
applied to conditionally reduce Obligations, but shall not be considered a
payment in respect of the Obligations unless such payment is of immediately
available federal funds or unless and until such check or other item of payment
is honored when presented for payment. Notwithstanding anything to the contrary
contained herein, any wire transfer or payment received by Bank after 12:00 noon
Pacific time shall be deemed to have been received by Bank as of the opening of
business on the immediately following Business Day. Whenever any payment to Bank
under the Loan Documents would otherwise be due (except by reason of
acceleration) on a date that is not a Business Day, such payment shall instead
be due on the next Business Day, and additional fees or interest, as the case
may be, shall accrue and be payable for the period of such extension.

         2.5.     FEES. Borrower shall pay to Bank the following:

                  (a)      Facility Fee. A Facility Fee equal to one-quarter of
one percent (.25%) of the $1,500,000 Revolving Line of Credit ($3,750.00) shall
be due on the Closing Date. Such Facility Fee shall be fully earned and
non-refundable when paid.

                  (b)      Bank Expenses. Upon demand from Bank, including,
without limitation, upon the date hereof, all Bank Expenses incurred through the
date hereof, including reasonable attorneys' fees and expenses and, after the
date hereof, all Bank Expenses, including reasonable attorneys' fees and
expenses, as and when they become due.

         2.6.     ADDITIONAL COSTS. In case any law, regulation, treaty or
official directive or the interpretation or application thereof by any court or
any governmental authority charged with the administration thereof or the
compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law):

                  (a)      subjects Bank to any tax with respect to payments of
principal or interest or any other amounts payable hereunder by Borrower or
otherwise with respect to the transactions contemplated hereby (except for taxes
on the overall net income of Bank imposed by the United States of America or any
political subdivision thereof);

                  (b)      imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit or similar requirement against assets held
by, or deposits in or for the account of, or loans by, Bank; or

                  (c)      imposes upon Bank any other condition with respect to
its performance under this Agreement, and the result of any of the foregoing is
to increase the cost to Bank, reduce the income receivable by Bank or impose any
expense upon Bank with respect to any loans, Bank shall notify Borrower thereof.
Borrower agrees to pay to Bank the amount of such increase in cost, reduction in
income or additional expense as and when such cost, reduction or expense is
incurred or determined, upon presentation by Bank of a statement of the amount
and setting forth Bank's calculation thereof, all in reasonable detail, which
statement shall be deemed true and correct absent manifest error.

         2.7.     TERM.

                  (a)      Except as otherwise set forth herein, this Agreement
shall become effective on the Closing Date and, subject to Section 12.7, shall
continue in full force and effect for a term ending on the Revolving Line
Maturity Date. Notwithstanding the foregoing, Bank shall have the right to
terminate its obligation to make Credit Extensions under

<PAGE>   10

this Agreement immediately and without notice upon the occurrence and during the
continuance of an Event of Default. Notwithstanding termination of this
Agreement, Bank's lien on the Collateral shall remain in effect for so long as
any Obligations are outstanding.

                  (b)      At such time as (i) the Bank is no longer obligated
under this Agreement (whether by the terms hereof or as a result of a release of
such obligations by Borrower) to make any further Credit Extensions, and (ii)
all obligations have been indefeasibly paid and satisfied in full, this
Agreement and the Loan Documents shall terminate and Bank shall release or cause
to be released, at the Borrower's cost and expense, all Liens granted by
Borrower to Bank under the Loan Documents as security for any of the
Obligations; provided, however, that any and all indemnity obligations of
Borrower arising under this Agreement or any other Loan Documents shall survive
the termination of this Agreement or such other Loan Documents.

                  (d)      payment of the fees and Bank Expenses then due
specified in Section 2.5 hereof;

                  (e)      such other documents, and completion of such other
matters, as Bank may reasonably deem necessary or appropriate; and

                  (f) execution and delivery of each Loan Document by Borrower.

         3.2.     CONDITIONS PRECEDENT TO ALL CREDIT EXTENSIONS. The obligation
of Bank to make each Credit Extension, including the initial Credit Extension,
is further subject to the following conditions:

                  (a)      timely receipt by Bank of the Payment/Advance Form as
provided in Section 2.1; and

                  (b)      the representations and warranties contained in
Section 5 shall be true and correct in all material respects on and as of the
date of such Payment/Advance Form and on the effective date of each Credit
Extension as though made at and as of each such date, and no Event of Default
shall have occurred and be continuing, or would result from such Credit
Extension. The making of each Credit Extension shall be deemed to be a
representation and warranty by Borrower on the date of such Credit Extension as
to the accuracy of the facts referred to in this Section 3.2(b).

4.       CREATION OF SECURITY INTEREST

         4.1.     GRANT OF SECURITY INTEREST. Borrower grants to Bank a
continuing security interest in, and control over, the property described in
Exhibit A attached hereto (the "Collateral") in order to secure prompt repayment
of any and all obligations and in order to secure prompt performance by Borrower
of each of its covenants and duties under (a) the Loan Agreement, as amended
from time to time, and any other agreements entered into between Bank and
Borrower (the "Loan Documents"), and (b) under the First Loan Agreement, as
amended from time to time, and any other agreements entered into between Bank
and Borrower in connection with the First Loan Agreement. Such security interest
constitutes a valid, first priority security interest in the presently existing
Collateral, and will constitute a valid, first priority security interest in
Collateral acquired after the date hereof. Borrower acknowledges that Bank may
place a hold on the deposit account pledged as Collateral.

         4.2.     DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED. Borrower shall
from time to time execute and deliver to Bank, at the request of Bank, all
Negotiable Collateral, all financing statements

<PAGE>   11

and other documents that Bank may reasonably request, in form satisfactory to
Bank, to perfect and continue perfected Bank's security interests in the
Collateral and in order to fully consummate all of the transactions contemplated
under the Loan Documents.

5.       REPRESENTATIONS AND WARRANTIES

         Borrower represents and warrants as follows:

         5.1      DUE ORGANIZATION AND AUTHORIZATION. Borrower and each
Subsidiary is duly existing and in good standing in its state of formation and
qualified and licensed to do business in, and in good standing in, any state in
which the conduct of its business or its ownership of property requires that it
be qualified.

         The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's formations documents, nor
constitute an event of default under any material agreement by which Borrower is
bound. Borrower is not in default under any agreement to which or by which it is
bound in which the default could cause a Material Adverse Change.

         5.2      COLLATERAL. Borrower has good title to the Collateral, free of
Liens except Permitted Liens. The Eligible Accounts are bona fide, existing
obligations, and the service or property has been performed or delivered to the
account debtor or its agent for immediate shipment to and unconditional
acceptance by the account debtor. Borrower has no notice of any actual or
imminent Insolvency Proceeding of any account debtor whose accounts are an
Eligible Account in any Borrowing Base Certificate. All Inventory is in all
material respects of good and marketable quality, free from material defects.
Borrower is the sole owner of the Intellectual Property, except for exclusive or
non-exclusive licenses granted to its customers in the ordinary course of
business. Each Patent is valid and enforceable and no part of the Intellectual
Property has been judged invalid or unenforceable, in whole or in part, and no
claim has been made that any part of the Intellectual Property violates the
rights of any third party except to the extent such claim could not reasonably
be expected to cause a Material Adverse Change.

         5.3      LITIGATION. Except as shown in the Schedule, if any attached,
there are no actions or proceedings pending or, to Borrower's knowledge,
threatened by or against Borrower or any Subsidiary in which an adverse decision
could reasonably be expected to cause a Material Adverse Change.

         5.4      NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS. All
consolidated financial statements for Borrower and any Subsidiary delivered to
Bank fairly present in all material respects Borrower's consolidated financial
condition and Borrower's consolidated results of operations. There has not been
any material deterioration in Borrower's consolidated financial condition since
the date of the most recent financial statements submitted to Bank.

         5.5      SOLVENCY. The fair salable value of Borrower's assets
(including goodwill minus disposition costs) exceeds the fair value of its
liabilities; the Borrower is not left with unreasonably small capital after the
transactions in this Agreement; and Borrower is able to pay its debts (including
trade debts) as they mature.

         5.6      REGULATORY COMPLIANCE. Borrower is not an "investment company"
or a company "controlled" by an "investment company" under the Investment
Company Act. Borrower is not engaged as one of its important activities in
extending credit for margin stock

<PAGE>   12

(under Regulations T and U of the Federal Reserve Board of Governors). Borrower
has complied in all material respects with the Federal Fair Labor Standards Act.
Borrower has not violated any laws, ordinances or rules, the violation of which
could cause a Material Adverse Change. None of Borrower's or any Subsidiary's
properties or assets has been used by Borrower or any Subsidiary or, to the best
of Borrower's knowledge, by previous Persons, in disposing, producing, storing,
treating, or transporting any hazardous substance other than legally. Borrower
and each Subsidiary has timely filed all required tax returns and paid, or made
adequate provision to pay, all material taxes, except those being contested in
good faith with adequate reserves under GAAP. Borrower and each Subsidiary has
obtained all consents, approvals and authorizations of, made all declarations or
filings with, and given all notices to, all government authorities that are
necessary to continue its business as currently conducted except where the
failure to do so could not reasonably be expected to cause a Material Adverse
Change.

         5.7      SUBSIDIARIES. Borrower does not own any stock, partnership
interest or other equity securities except for Permitted Investments.

         5.8      FULL DISCLOSURE. No representation, warranty or other
statement of Borrower in any certificate or written statement given to Bank
taken together with all such certificates and written statements given to Bank
contains any untrue statement of a material fact or omits to state a material
fact necessary to make the statements contained in the certificates or
statements not misleading (it being recognized by Bank that the projections and
forecasts provided by Borrower in good faith and based upon reasonable
assumptions are not to be viewed as facts and that actual results during the
period or periods covered by any such projections and forecasts may differ from
the projected or forecasted results).

6.       AFFIRMATIVE COVENANTS

         Borrower covenants and agrees that, until payment in full of all
outstanding Obligations, and for so long as Bank may have any commitment to make
a Credit Extension hereunder, Borrower shall do all of the following:

Subsidiaries' corporate existence and good standing in their jurisdiction of
incorporation and maintain qualification in each jurisdiction in which the
failure to so qualify could have a Material Adverse Effect. Borrower shall
maintain, and shall cause each of its Subsidiaries to maintain, to the extent
consistent with prudent management of Borrower's business, in force all
licenses, approvals and agreements, the loss of which could have a Material
Adverse Effect.

         6.2.     GOVERNMENT COMPLIANCE. Borrower shall meet, and shall cause
each Subsidiary to meet, the minimum funding requirements of ERISA with respect
to any employee benefit plans subject to ERISA. Borrower shall comply, and shall
cause each Subsidiary to comply, with all statutes, laws, ordinances and
government rules and regulations to which it is subject, noncompliance with
which could have a Material Adverse Effect or a material adverse effect on the
Collateral or the priority of Bank's Lien on the Collateral.

         6.3.     FINANCIAL STATEMENTS, REPORTS, CERTIFICATES. Borrower shall
deliver to Bank: (a) as soon as available, but in any event within forty-five

during such period, in a form and certified by an officer of Borrower reasonably
acceptable to Bank; and (b) as soon as available, but in any event within ninety
(90)

<PAGE>   13

days after the end of Borrower's fiscal year, audited consolidated financial
statements of Borrower prepared in accordance with GAAP, consistently applied,
together with an unqualified opinion on such financial statements of an
independent certified public accounting firm reasonably acceptable to Bank.

         6.4.     TAXES. Borrower shall make, and shall cause each Subsidiary to
make, due and timely payment or deposit of all material federal, state, and
local taxes, assessments, or contributions required of it by law, and will
execute and deliver to Bank, on demand, appropriate certificates attesting to
the payment or deposit thereof; and Borrower will make, and will cause each
Subsidiary to make, timely payment or deposit of all material tax payments and
withholding taxes required of it by applicable laws, including, but not limited
to, those laws concerning F.I.C.A., F.U.T.A., state disability, and local,
state, and federal income taxes, and will, upon request, furnish Bank with proof
satisfactory to Bank indicating that Borrower or a Subsidiary has made such
payments or deposits; provided that Borrower or a Subsidiary need not make any
payment if the amount or validity of such payment is (i) contested in good faith
by appropriate proceedings , (ii) is reserved against (to the extent required by
GAAP) by Borrower and (iii) no lien other than a Permitted Lien results.

         6.5.     PRINCIPAL DEPOSITORY. Borrower shall maintain its principal
depository and operating accounts with Bank.

         6.6.     FURTHER ASSURANCES. At any time and from time to time Borrower
or a Subsidiary shall execute and deliver such further instruments and take such
further action as may reasonably be requested by Bank to effect the purposes of
this Agreement.

7.       NEGATIVE COVENANTS

hereunder shall be available and until payment in full of the outstanding
Obligations or for so long as Bank may have any commitment to make any Advances,

without prior written Bank approval (which may be granted or denied by Bank's
sole and absolute discretion):

         7.1.     CHANGES IN BUSINESS, OWNERSHIP, OR MANAGEMENT, BUSINESS
LOCATIONS. Engage in any business other than the businesses currently engaged in
by Borrower or a Subsidiary and any business substantially similar or related
thereto (or incidental thereto). Borrower will not, without at least thirty (30)

add any new offices or business locations, other than remote offices for
employees which do not include any material assets.

         7.2.     COMPLIANCE. Become an "investment company" or a company

purpose; fail to meet the minimum funding requirements of ERISA; permit a
Reportable Event or Prohibited Transaction, as defined in ERISA, to occur; fail
to comply with the Federal Fair Labor Standards Act or violate any other law or

entered into between Borrower and Bank, so long as: (1) the market value of the
Collateral does not fall below 100% of the value of the Revolving Line of
Credit, (2) an Event of Default has not occurred, and, if necessary, Borrower

9.       BANK'S RIGHTS AND REMEDIES

         9.1.     RIGHTS AND REMEDIES. Upon the occurrence and during the
continuance of an Event of Default, Bank may, at its election, without notice of
its election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

                  (a)      Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 8 all Obligations shall become immediately due and payable without any
action by Bank);

                  (b)      Cease advancing money or extending credit to or for
the benefit of Borrower under this Agreement or under any other agreement
between Borrower and Bank;

                  (c)      Without notice to or demand upon Borrower, make such
payments and do such acts as Bank considers necessary or reasonable to protect
its security interest in the Collateral. Borrower agrees to make the Collateral
available to Bank, as Bank may designate.

<PAGE>   16

                  (d)      Without notice to Borrower, set off and apply to the
Obligations any and all (i) balances and deposits of Borrower or any Subsidiary
held by Bank, or (ii) indebtedness at any time owing to or for the credit or the
account of Borrower or any Subsidiary held by Bank; and

                  (e)      Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

         9.2.     BANK EXPENSES. If Borrower fails to pay any amounts or furnish
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the following:
(a) make payment of the same or any part thereof; and (b) set up such reserves
under the Revolving Line of Credit as Bank deems necessary to protect Bank from
the exposure created by such failure. Any amounts so paid or deposited by Bank
shall constitute Bank Expenses, shall be immediately due and payable, and shall
bear interest at the then applicable rate hereinabove provided, and shall be
secured by the Collateral. Any payments made by Bank shall not constitute an
agreement by Bank to make similar payments in the future or a waiver by Bank of
any Event of Default under this Agreement.

         9.3.     REMEDIES CUMULATIVE. Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not expressly set forth herein as
provided under the Code, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

         9.4.     DEMAND; PROTEST. Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment, notice
of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be liable.

         9.5.     HOLD ON COLLATERAL. Borrower agrees that, until the Revolving
Line Maturity Date, until payment in full of all outstanding obligations under
the Revolving Line of Credit, the First Loan Agreement and this Loan Agreement,
and for so long as Bank may have any obligations to extend Advances under the
Revolving Line of Credit, Bank may hold and refuse to release the Collateral to
any party, including Borrower.
