               ---------------------
outstanding principal amount prior to maturity at the rate of twelve percent
(12%) per annum, payable in arrears on the Maturity Date. All computations of
interest on this Note shall be made on the basis of a year of 360 days, in each
case for the actual number of days (including the first day, but excluding the
last day) occurring in the period for which such interest is payable. In
computing interest on this Note, the first day of an interest period shall be
included and the date of payment or the expiration of an interest period, as the
case may, shall be excluded.

     The entire principal amount of this Note, together with any accrued but
unpaid interest thereon and any other sums due and payable hereunder, shall be
due and payable on the latter of (i) the consummation of the sale of any class
of Company capital stock providing the Company with a minimum of $1,500,000.00
in proceeds or (ii) March 11, 2002 (the "Maturity Date"), unless such
indebtedness is, pursuant to Section 5.1 hereof, converted into Common Stock
                             -----------

principal at a variable default rate equal to twelve (12%) percent per annum.
The Company shall issue seventy-five thousand shares (75,000) of Common Stock on

               ---------------------------
whether of principal or interest, shall be made in lawful money of the United
States of America at the principal executive offices of the Company, specified
pursuant to Section 8.1; provided, however, at the option of the Company,
            -----------  --------  -------
payments may be made by check mailed to the Holder at Holder's address as
specified pursuant to Section 8.1, or by wire transfer of funds to an account at
                      -----------
such bank in the United States of America as Holder shall designate. Whenever
any payment under this Note shall be stated to be due on a day other than a
Business Day, such payment shall be made on the next succeeding Business Day,
and such extension of time shall, in such case, be included in the computation
of payment of interest.

          2.3  Optional Prepayment; Non-Transferability. The Company may, in its
               ----------------------------------------
discretion, pay the Note in whole or in part at any time, without premium or

interest and then to principal. Except as permitted in accordance with Section

          2.4  Events of Default. The occurrence of any of the following events
               -----------------
shall constitute an Event of Default:

          prepayment required under this Note, including, without limitation,
          any payment of principal or interest, and such failure continues for

          failure.

               (b)  The Company shall (i) make an assignment for the benefit of
          creditors, (ii) petition or apply for the appointment of a liquidator,
          receiver or the like, (iii) commence, acquiesce in or consent to any
          proceeding relating to it under any bankruptcy, insolvency or similar
          law, or (iv) admit in writing its inability to pay its debts as they
          mature; or

               (c)  The voluntary filing by the Company of, or consent by, the
          Company to any petition in bankruptcy or any reorganization,
          arrangement, composition, readjustment, liquidation, dissolution or
          similar relief with respect to the Company, or the admission in
          writing by the Company of its inability to pay its debts as they
          become due.

               (d)  A decree, judgment, or order by a court of competent
          jurisdiction shall have been entered adjudging the Company, or
          ordering relief against the Company in response to the commencement of
          any involuntary bankruptcy case, or approving as properly filed a
          petition seeking reorganization or liquidation of the Company under
          any bankruptcy or similar law, and such decree or order shall have
          continued undischarged and unstayed for a period of sixty (60) days;
          or a decree or order of a court of competent jurisdiction over the
          appointment of a receiver, liquidator, trustee, or assignee in
          bankruptcy or insolvency of the Company, or of the property of the
          Company, or for the winding up or liquidation of the affairs of the
          Company, shall have been entered, and such decree, judgement, or order
          shall have remained in force undischarged and unstayed for a period of
          sixty (60) days;

               (e)  A default in the payment of principal or interest or with
          respect to any Indebtedness in excess of $100,000 or any other default
          or an event of default by the Company shall occur with respect to any
          Indebtedness in excess of $100,000 which would entitle the holder of
          such Indebtedness to accelerate the maturity thereof or require any
          prepayment thereon;

               (f)  One or more final judgments not covered by insurance for the
          payment of money, or the issuance of any warrant of attachment against
          any portion of the property or assets of the Company which, in the
          aggregate, equal to or exceed $100,000 at any one time, shall be
          entered against the Company by a

                                       9

<PAGE>

          court of competent jurisdiction and not be stayed, bonded or
          discharged for a period (during which execution shall not be
          effectively stayed) of thirty (30) days or more (or, in the case of
          any such final judgment which provides for payment over time, which
          shall so remain unstayed, unbonded or undischarged beyond any
          applicable payment date provided therein);

               (g)  The failure by the Company to observe or perform any
          covenant, agreement or warranty contained in this Note or the Right of
          First Refusal Agreement (other than a default otherwise expressly
          enumerated above) and continuance of such default or event of default
          for thirty (30) days after notice to the Company thereof.

     Upon the occurrence of any of the foregoing Events of Default, the entire
unpaid balance hereof, together with unpaid interest thereon, shall at the
option of Holder, and upon written notice from Holder (except with respect to
defaults under clauses (b), (c) or (d) as to which the Event of Default shall be
automatic and no notice shall be required), become immediately due and payable,
and Holder may, subject to the provisions of Section 4, forthwith exercise the
                                             ---------
remedies available to Holder at law and in equity as well as those remedies set
forth in this Note, and one or more executions may forthwith issue on any
judgment or judgments obtained by virtue thereof; and no failure on the part of
Holder to exercise any of Holder's rights hereunder shall be deemed a waiver of
any such rights or of any default.

     Such acceleration of the maturity of amounts due under this Note shall not
affect, and shall be cumulative of, any other rights and remedies which the
Holder may have at law, in equity or otherwise. All rights and remedies
hereunder shall be cumulative and in addition to those provided by law, and may
be exercised separately, concurrently or successively. Notwithstanding the fact
that a failure by the Company to pay any payment of principal or interest on its
stated due date under this Note may occur by reason of the subordination
provisions under Section 4 of this Note, such failure to pay shall nevertheless
                 ---------
for all purposes under this Note constitute an Event of Default entitling Holder
to accelerate the maturity of this Note and/or to pursue all of Holder's other
rights and remedies under this Note and other rights and remedies Holder may
have at law with respect to such Event of Default, subject to the limitations
and other provisions of Section 4 of this Note.

and until all of the Senior Indebtedness shall have been irrevocably paid in
full, and the Company's obligations under any applicable agreement with respect
to Senior Indebtedness (including, without limitation, any applicable loan

     5.  Conversion.
         ----------

         5.1 Conversion by the Holder. The Holder may, at any time, convert all
             ------------------------
or any portion of the then outstanding principal amount of this Note and any
accrued but unpaid interest hereon into shares of Common Stock at a Conversion
Price equal to Fifty Cents ($.50) per share of Common Stock (or at the current
adjusted Conversion Price if an adjustment has been made as provided herein).

         5.2 Stock Splits; Reverse Stock-Splits. In case outstanding shares of
             ----------------------------------
Common Stock shall be subdivided into a greater number of shares of Common
Stock, the Conversion Price in effect at the opening of business on the day
following the day upon which such subdivision becomes effective shall be
proportionately reduced, and, conversely, in case outstanding shares of Common
Stock shall be combined into a smaller number of shares of Common Stock, the
Conversion Price in effect at the opening of business on the day following the
day upon which such combination becomes effective shall be proportionately
increased, such reduction or increase, as the case may be, to become effective
immediately after the opening of

                                       15

<PAGE>

business on the day following the day upon which such subdivision or combination
becomes effective.

         5.3 Provisions in Case of Consolidation or Merger. In case of any
             ---------------------------------------------
consolidation of the Company with, or merger of the Company into, any other
Person, any merger of another Person into the Company (other than a merger which
does not result in any reclassification, conversion, exchange or cancellation of
outstanding shares of Common Stock of the Company) the Holder shall have the
right thereafter during the period in which this Note shall be convertible as
specified, to convert this Note only into the kind and amount of securities,
cash and other property receivable, if any, upon such consolidation, merger,
sale or transfer by a holder of the number of shares of Common Stock of the
Company into which this Note might have been converted immediately prior to such
consolidation, merger, sale or transfer, assuming such holder of Common Stock of
the Company (i) is not a Person with which the Company consolidated or into
which the Company merged or which merged into the Company or to which such sale
or transfer was made, as the case may be ("Constituent Person"), or an Affiliate
of a Constituent Person and (ii) failed to exercise his rights of election, if
any, as to the kind or amount of securities, cash and other property receivable
upon such consolidation, merger, sale or transfer (provided that if the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger sale or transfer is not the same for each share of Common
Stock of the Company held immediately prior to such consolidation, merger, sale
or transfer by other than a Constituent Person or an Affiliate thereof and in
respect of which such rights of election shall not have been exercised
("non-electing share"), then, for the purpose of this Section 5.3, the kind and
                                                      -----------
amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer by each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares). The above provisions of this Section 5.3 shall similarly
                                                   -----------
apply to successive consolidations, mergers, sales or transfers.

         5.4 Adjustment in Number of Securities. Upon each adjustment of the
             ----------------------------------
Conversion Price pursuant to the provisions of Section 5 of this Note, the
                                               ---------
number of shares of Common Stock issuable upon exercise at the adjusted
Conversion Price shall be adjusted to the nearest full amount by multiplying a
number equal to the Conversion Price in effect immediately prior to such
adjustment by the number of shares of Common Stock issuable upon exercise of the
conversion right immediately prior to such adjustment and dividing the product
so obtained by the adjusted Conversion Price.

         5.5 Validity of Note. Irrespective of any adjustments or changes in the
             ----------------
Conversion Price or the amount of securities issuable upon exercise of the
conversion right, this Note shall continue to express the Conversion Price per
share and the amount of securities issuable thereunder as of the date this Note
was originally issued; provided, the Holder shall be entitled to exercise the
right represented by this Note after giving effect to each such adjustment and
change, and this Note shall be deemed to incorporate each such adjustment and
change as if a new Note reflecting each such adjustment and change had been
issued to the Holder.

         5.6 Elimination of Fractional Interests. The Company shall not be
             -----------------------------------
required to issue certificates representing fractions of shares of Common Stock
upon the exercise of the conversion rights set forth in this Section 5, nor
                                                             ---------
shall it be required to issue scrip or pay cash in

                                       16

<PAGE>

lieu of such fractional interests, it being the intent of the parties that all
fractional interests shall be eliminated by rounding any fraction up or down to
the nearest whole number of shares of Common Stock or other securities,
properties or rights. If a fraction of a share would otherwise be issuable on
conversion of this Note, the Company will in lieu of such issuance pay the cash
value of that fractional share.

         5.7 Unit Offerings. In case the Company shall offer its Common Stock as
             --------------
part of an offering of units of equity securities, the per share or per share
equivalent stock price and per share or per share equivalent Conversion Price
shall be determined by dividing the number of shares in the Unit by the Closing
Price of the Unit on the applicable date or dates. In case the Company shall
offer its Common Stock as part of a unit of equity and debt securities, the per
share price or per share equivalent stock price shall be determined by dividing
the number of shares in the unit by the remainder of the closing price of the
Unit on the applicable date or dates, minus the principal face amount of the
                                      -----
debt security component of the Unit.

         5.8 Issuance of Stock on Conversion. As soon as reasonably practicable
             -------------------------------
after a conversion of this Note, in whole or in part, pursuant to Section 5, the
                                                                  ---------
Company at its expense will cause to be issued in the name of and delivered to
the Holder of this Note, a certificate or certificates for the number of shares
of Common Stock to which that Holder shall be entitled on such conversion
(bearing such legends as may be required under applicable state and federal
securities laws in the opinion of the Company, after consultation with counsel).
Such conversion shall be deemed to have been made immediately prior to the close
of business on the Forced Conversion Date or the Voluntary Conversion Date. No
fractional shares will be issued on conversion of this Note.

of the right to insist upon and to enforce strict compliance by the Company with
all of the covenants and agreements herein. Delay, omission or waiver on any one
occasion shall not be deemed a bar to, or waiver of, the same or any other right
on any future occasion. No waiver by Holder may be made under this Note except
in written notice signed by Holder and given to the Company in accordance with
Section 8.1. No notice to or demand on the Company, in any case, shall entitle
-----------
it to any other or further notice of demand in other similar circumstances.

         8.5 Binding Effect. This Note shall be binding upon the Company and its
             --------------
successors and assigns and shall inure to the benefit of the Holder and his
heirs, executors, administrators, legal representatives and assigns. Company may
assign this Note so long as it remains liable for the obligations hereunder.

         8.6 Interpretation; Construction; Section Headings. Except as may be
             ----------------------------------------------
otherwise noted in context, all references to "Sections" shall be deemed to
refer to the sections or subsections, as appropriate, of this Note.

              (c) Section headings appearing in this Note are inserted solely as
         reference aids for the ease and convenience of the reader; they shall
         not be deemed to modify, limit or define the scope or substance of the
         provisions they introduce, nor shall they be used in construing the
         intent or effect of such provisions.

         8.7  Governing Law. This Agreement, including all matters related to
              -------------
validity, construction, performance and enforcement hereof, shall be governed by
and construed in accordance with the internal laws of the State of Delaware,
without regard to choice of law or conflicts or law principles except to the
extent the Communications Act of 1934, as amended and as interpreted and applied
by judicial and regulatory authorities, including the Federal Communications
Commission, supercedes such state law and except that the arbitration provisions
shall be governed by the federal laws of the United States of America.

         8.8  Severability. If any provision of this Note is held to be invalid
              ------------
or unenforceable by a court of competent jurisdiction, the other provisions of
this Note shall remain in full force and effect and shall be liberally construed
in favor of Holder.

         8.9  Waiver of Notice. The Company waives notice under this Note
              ----------------
(except as expressly provided for this Note), demand for payment, presentment
for payment, protest, or notice of protest and non-payment with respect to this
Note, and the Company consents to any extension or postponement of time of
payment of this Note and to any other indulgence with respect to this Note
without notice thereby to the Company.

         8.10 Attorney's Fees. In addition to all principal and accrued interest
              ---------------
on this Note, the Company agrees to pay to Holder or other permitted assignee or
transferee without duplication of amounts payable hereunder all reasonable court
costs incurred by Holder or other permitted assignee or transferee in collecting
this Note through any legal proceedings, and reasonable attorneys' fees not to
exceed ten percent (10%) of the unpaid principal and accrued interest owing on
this Note when and if this Note is placed in the hands of an attorney for
collection after an Event of Default, as herein defined.

         8.11 Time. Time is of the essence under this Note.
              ----

         8.12 Maximum Limit On Interest. The provisions of this Note and of all
              -------------------------
agreements between the Company and Holder, whether now existing or hereafter
arising and whether written or oral, are hereby expressly limited so that, in no
contingency or event whatsoever, whether by reason of acceleration of the
maturity of this Note or otherwise, shall the amount contracted for, charged,
taken, received, paid or agreed to be paid to Holder for the use, forbearance,
or detention of the money loaned under this Note or otherwise, exceed the
Highest Lawful Rate, as herein defined. If, from any circumstance whatsoever,
performance or fulfillment of any provision hereof or of any agreement between
the Company and Holder shall, at the time performance or fulfillment of such
provision shall be due, exceed the Highest Lawful Rate or otherwise transcend
the limit of validity prescribed by applicable law, then, ipso facto, the
obligation to be performed or fulfilled shall be reduced to the Highest Lawful
Rate, and if, from any circumstance whatsoever, Holder shall ever receive
anything of value deemed interest

                                       21

<PAGE>

under applicable law in excess of interest at the Highest Lawful Rate, an amount
equal to any excessive interest shall be applied to the reduction of the
principal balance owing hereunder, and not to the payment of interest, or if
such excessive interest exceeds the unpaid balance of principal hereof, then
such excess shall be refunded to the Company. It is the intent of the parties
hereto that the Company shall not, under any circumstances, be required to pay,
nor shall Holder be entitled to collect, any interest which is in excess of the
maximum legal rate permitted under the laws of the applicable jurisdiction. All
sums paid or agreed to be paid to Holder for the use, forbearance, or detention
of the indebtedness of the Company to Holder, shall, to the extent permitted by
applicable law, be amortized, prorated, allocated and spread through the full
term of this Note until payment in full, so that the rate of interest on account
of such indebtedness will not at any time exceed the Highest Lawful Rate. The
Provisions of this paragraph shall control all agreements between the Company
and Holder. The term "Highest Lawful Rate" as used herein shall mean the maximum
non-usurious rate of interest permitted by whichever of applicable federal or
Georgia law from time to time permits the highest maximum non-usurious interest
at rate with respect to this Note.

         8.13 Mutilated, Destroyed, Lost and Stolen Notes. Subject to compliance
              -------------------------------------------
with the other terms of this Section, if any mutilated Note is surrendered to
the Company, the Company shall execute, authenticate and deliver in exchange
therefor a new Note of like tenor and principal amount and bearing a number not
contemporaneously outstanding. If there shall be delivered to the Company (a)
evidence to its satisfaction of the destruction, loss or theft of any such Note,
and (b) such note or indemnity as may be required by the Company to save the
Company and all of its agents harmless, then, in the absence of notice to the
Company that such Note has been acquired by a bona fide purchaser, the Company
shall execute, authenticate and deliver, in lieu of any such destroyed, lost or
stolen Note, a new Note of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Note has become
     or is about to become due and payable, the Company in its discretion may,
     instead of issuing a new Note, pay such Note. Upon the issuance of any new
     Note under this Section, the Company may require the payment of a sum
     sufficient to cover any tax or other governmental charge that may be
     imposed in relation thereto and any other expenses (including the fees and
     expenses of its counsel) connected therewith. Every new Note issued
     pursuant to this Section in lieu of any destroyed, lost or stolen Note
     shall constitute an original additional contractual obligation of the
     Company, whether or not the destroyed, lost or stolen Note shall be at any
     time enforceable by anyone, and shall be entitled to all the benefits of
     this Note equally and proportionately with any and all other Notes of the
     series (if any) of which this Note is a part. The provisions of this
     Section are exclusive and shall preclude (to the extent lawful) all other
     rights and remedies with respect to the replacement or payment of
     mutilated, destroyed, lost or stolen Notes.

         8.14 No Recourse Against Others. A director, officer, employee or
              --------------------------
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under this Note for any claim based on, in respect of
or by reason of such obligations or their creation. Each Holder by accepting a
Note waives and releases all such liability. The waiver and release are part of
the consideration for the issuance of this Note.

                                       22

         8.15 Authentication. This Note shall not be valid until authenticated
              --------------
by the manual signatures of the President of the Company and its Secretary or an
Assistant Secretary or an authenticating agent.

         8.16 Exclusive Jurisdiction and Venue. Any suit, action or proceeding
              --------------------------------
with respect to this Note shall be brought exclusively in the state courts
located in either Cobb County, Georgia or Fulton County, Georgia or in the
United States District Court for the Northern District of Georgia, Atlanta
Division. By execution and delivery of this Note, Holder accepts for itself the
exclusive venue in the State of Georgia and the exclusive jurisdiction of the
aforesaid courts, and irrevocably agrees to be bound by any judgment, subject to
all rights of appeal, rehearing and the like, rendered thereby in connection
with this Note. ALL PARTIES HEREBY IRREVOCABLY WAIVE ANY OBJECTION WHICH THEY
MAY NOW OR HEREAFTER HAVE TO THE PERSONAL JURISDICTION OR VENUE OF ANY SUIT,
ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE BROUGHT IN SUCH
COURTS AND HEREBY FURTHER IRREVOCABLY WAIVE ANY CLAIM THAT SUCH SUIT, ACTION, OR
PROCEEDING BROUGHT IN ANY SUCH COURTS HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

     IN WITNESS WHEREOF, the Company has caused this Note to be signed in its
name and executed as a sealed instrument on the day and year first written
above.
