                                 PROMISSORY NOTE


$30,000.00                                              October 8, 1998


         Henry M. Baroco (hereinafter referred to as "Maker"), for value
received, hereby promises to pay to the order of TOWNE SERVICES, INC., a Georgia
corporation (hereinafter referred to as "Payee"), the aggregate principal sum of
THIRTY THOUSAND DOLLARS ($30,000.00) on February 8, 2000 or (ii) the date that
Maker sells any shares of capital stock of Payee that are held by Maker,
together with interest on the unpaid principal balance at the rate of 8.5% per
annum, compounded annually. The principal hereof and the interest thereon are
payable at 3295 River Exchange Drive, Suite 350, Atlanta, Georgia 30092, or at
such other place as Payee may from time to time designate to Maker in writing,
in coin or currency of the United States of America.

         Maker may, at any time and from time to time, prepay all or any portion
of the principal of this Note remaining unpaid, without penalty or premium.
Prepayments shall be applied first to the payment of accrued but unpaid interest
on this Note and the balance to principal.

         If any of the following events (an "Event of Default") shall occur and
be continuing for any reason whatsoever (and whether such occurrence shall be
voluntary or involuntary or come about or be effected by operation of law or
otherwise), then this Note shall thereupon be and become, forthwith due and
payable, without any further notice or demand of any kind whatsoever, all of
which are hereby expressly waived:

                (a) If Maker defaults in the payment of principal or interest on
                this Note when and as the same shall become due and payable and
                such default continues for 20 days after Maker receives notice
                from Payee of such default; or

                (b) If Maker makes an assignment for the benefit of creditors or
                admits in writing an inability to pay his or its debts generally
                as they become due;

                (c) If an order, judgment or decree is entered adjudicating
                 Maker bankrupt or insolvent;

                (d) If Maker petitions or applies to any tribunal for the
                appointment of a trustee or receiver of Maker, or of any
                substantial part of the assets of Maker, or commences any
                proceedings relating to Maker under any bankruptcy,
                reorganization, arrangement, insolvency, readjustment of debt,
                dissolution or liquidation law of any jurisdiction, whether now
                or hereafter in effect; or

                (e) If any such petition or application is filed, or any such
                proceedings are commenced, against Maker, and Maker by any act
                indicates its approval thereof, 

<PAGE>   2

                consent thereto, or acquiescence therein, or an order is 
                entered appointing any such trustee or receiver, or approving
                the petition in any such proceedings, and such order remains
                unstayed and in effect for more than 90 days.

         This Note is with full recourse to any assets of Maker.

         Any failure on the part of Payee at any time to require the performance
by Maker of any of the terms or provisions hereof, even if known, shall in no
way affect the right thereafter to enforce the same, nor shall any failure of
Payee to insist on strict compliance with the terms and conditions hereof be
taken or held to be a waiver of any succeeding breach or of the right of Payee
to insist on strict compliance with the terms and conditions hereof.

         Time is of the essence.

         This Note shall be governed by, and enforced and interpreted in
accordance with, the laws of the State of Georgia without regard to the
principles of conflict of laws.

         In the event this note, or any part hereof, is collected by or through
an attorney-at-law, Maker agrees to pay all costs of collection including, but
not limited to, attorneys' fees equal to 15% of the principal and interest then
due. In the event that Maker fails to make any payment when due, Payee shall
provide written notice of default to Maker, which notice shall allow Maker ten
(10) days from the date of receipt of such notice in which to cure such default.
If such default is not cured within the time allowed, the balance hereof shall
be deemed to be immediately accelerated without further notice to Maker.

         IN WITNESS WHEREOF, Maker has executed this Note under seal as of the
date first set forth above.
