         which shall be subordinated in substantially the same manner as the

         2.    Terms of Note.
               -------------

               2.1   Interest and Maturity. This Note shall bear interest on the
                     --------------------
outstanding principal amount prior to maturity at the rate of ten percent (10%)
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 March 31, 2003 (the "Maturity Date"), unless such
indebtedness is, pursuant to Section 5.1 hereof, converted into Common Stock
                             -----------
prior to such date.

         All past due principal and interest under this Note shall bear interest
from maturity, or from the date of acceleration, as the case may be, of such
principal at a variable default rate equal to ten percent (10%) per annum
increased by two percent (2%) per annum for each thirty (30) day period or
portion thereof during which an Event of Default is in existence and continuing
with respect to this Note, up to the Highest Lawful Rate. For example, if the
Note is not paid at its scheduled Maturity Date on March 31, 2003, the interest
rate per annum would increase to twelve percent (12%) per annum on March 31,
2003, fourteen percent (14%) per annum on April 30, 2003, sixteen percent (16%)
on May 30, 2003, and so on. Likewise, for example, if an Event of Default
occurred on September 1, 2002 and was cured on October 15, 2002, the interest
rate would increase to twelve percent (12%) per annum on September 1, 2002 and
to fourteen percent (14%) per annum on October 1, 2002 and would be restored to
ten percent (10%) per annum on October 15, 2002.

         2.2   Manner and Place of Payment. All payments due under this Note,
               ---------------------------
whether of principal or interest, shall be made in lawful money of the United
States of America at the

                                       10

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
penalty, and any partial prepayment shall be applied first to accrued but unpaid
interest and then to principal. Except as permitted in accordance with Section
                                                                       -------
7, the Holder shall not sell, assign, transfer, pledge, give or otherwise
-
dispose of all or any part of its respective rights or obligations under this
Note.

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

               (a) The Company shall fail to pay when due any payment or
         prepayment required under this Note, including, without limitation, any
         payment of principal or interest, and such failure continues for ten
         (10) days after the Holder notifies the Company in writing of such
         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

               (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,

                                       11

<PAGE>

                  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 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

                                       12

<PAGE>

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.
                                                   ---------

         3.   Negative Covenants. The Company covenants and agrees that, until
              ------------------
payment in full of all of this Note, the Company will not, at any time:

              3.1 Limitation on Other Senior Subordinated Indebtedness. Create,

incur, issue, assume, guarantee or otherwise become liable for any Indebtedness
that is subordinate or junior in right of payment to any Senior Indebtedness of

                  ------------------------
successors and assigns, covenants and agrees and Holder by its acceptance hereof
likewise covenants and agrees that (a) the payment of the principal of and
interest on the Note, and (b) any payment on account of the acquisition or
redemption of the Note is hereby expressly subordinated, to the extent and in
the manner hereinafter set forth, in right of payment to the prior payment in
full of all Senior Indebtedness and that these provisions are for the benefit of
the holders of Senior Indebtedness.

              4.2 No Demand for Payment; Limitations on Payments. Unless the
                  ----------------------------------------------
authorized agent with authority to act for holders of Senior Indebtedness or
requisite holders of Senior Indebtedness shall have given prior written consent
otherwise, the Holder will not ask, demand, sue for, take or receive from any
Person or party, whether a direct or indirect obligor on the Note, by set-off or
any manner, the whole or any part of the principal of and/or the interest on the
Note, or any payment or distribution of any kind (whether in cash, property or
securities), including any payment that may be payable by reason of any other
indebtedness of the Company being subordinated to payment of this Note, unless
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
agreement or purchase agreement), shall have terminated; provided, however,
                                                         --------  -------
that:

                  (a) the Company may make regularly scheduled (unaccelerated)
              interest payments on the Note in accordance with the terms
              hereof as in effect on the date hereof, so long as no Default
              or Event of Default (in each case, as defined in any loan,
              purchase or other agreement with respect to Senior
              Indebtedness) is in existence at the time of such payment or
              would result from the making of such payment,

<PAGE>

                  (b)  may make payments following the expiration of a payment
              blockage period under Section 4.3, but only as provided in Section
                                    -----------                          -------
              4.3 of this Agreement;
              ---

                  (c)  this Note may be converted to Common Stock or any other
              equity security of the Company as provided in Section 5 of this
                                                            ---------
              Agreement; and

              permitted (i) by the terms of its Senior Indebtedness, or (ii)
              pursuant to consents from the necessary holders of Senior
              Indebtedness or a combination thereof.

              4.3 Limitations on Payments; Defaults. In the event that any
                  ---------------------------------
default or event of default (as defined in any loan agreement, purchase
agreement or any other agreement with respect to any Senior Indebtedness) in the
observance of any term of any Senior Indebtedness shall occur and be continuing,
then:

                  (a)  if such default is other than a payment default or a
              default which results in the acceleration of the maturity date of
              such Senior Indebtedness, no payment (including any payment that
              may be payable by reason of any other indebtedness of the Company
              being subordinated to payment of this Note) shall be made by or on
              behalf of the Company for or on account of this Note, and the
              Holder shall not take or receive from the Company, directly or
              indirectly, in cash or other property or by set-off or in any
              other manner, including, without limitation, from or by way of

              blockage period that may be provided for in any Designated Senior
              Indebtedness with respect to this Note; provided, however, that no

              such payment blockage period shall exist more than once in any 365
              consecutive day period, nor shall any such payment blockage period
              exceed 179 consecutive days in any 365 consecutive day period and,
              upon the maturity of any Senior Indebtedness then due by lapse of
              time, acceleration, default by the Company or otherwise, then all
              such matured Senior Indebtedness then due shall first be paid in
              full before any additional payment on account of principal or
              interest is made on the Note, and

                  (b)  if such default is a payment default or a default which
              results in the acceleration of the maturity date of such Senior
              Indebtedness, no payment (including any payment that may be
              payable by reason of any other indebtedness of the Company being
              subordinated to payment of this Note) shall be made by or on

              at the time be outstanding);

                   (b)  Any payment or distribution of assets of the Company of
              any kind or character, whether in cash, property or securities
              (other than shares of stock of the Company as reorganized or
              readjusted, or securities of the Company or any other corporation
              provided for by a plan of reorganization or readjustment, the
              payment of which is subordinated to the payment of all Senior
              Indebtedness which may at the time be outstanding), to which the
              Holder of the Note would be entitled, except for the provisions of
              this Section 4, shall be paid by the liquidating trustee or agent
                   ---------
              or other person making such payment or distribution, whether a
              trustee in bankruptcy, a receiver or liquidating trustee or other

              evidencing any such Senior Indebtedness may have been issued,
              ratably according to the aggregate amounts remaining unpaid on
              account of the principal of the Senior Indebtedness held or
              represented by each for application in the case of cash or as
              collateral (in the case of non cash assets) for the payment or
              prepayment of Senior Indebtedness, in each case, to the extent
              necessary to make payment in full of all Senior Indebtedness
              remaining unpaid, after giving effect to any concurrent payment or
              distribution or provision therefor to the holders of such Senior
              Indebtedness; and

              4.5  Payments Received in Trust. In the event that,
                   --------------------------
notwithstanding the foregoing, any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities (other
than shares of stock of the Company as reorganized or readjusted, or securities
of the Company or any other corporation provided for by a plan of reorganization
or readjustment, the payment of which is subordinated to the payment of all
Senior Indebtedness which may at the time be outstanding), shall be received by
the Holder on account of interest or principal on the Note not due or payable
prior to the happening of any of the events described in Section 4.3 or Section
                                                         -----------    -------

such payment or distribution shall be received in trust for the benefit of the
holders of Senior Indebtedness and shall be paid over to the holders of Senior
Indebtedness remaining unpaid or to their representative or representatives, or
to the trustee or trustees under any indenture under which any instruments
evidencing any of such Senior Indebtedness may have been issued, ratably as
aforesaid, in the same form as received (with any necessary endorsement) for
application in the case of cash or as collateral (in the case of non cash
assets) for the payment or prepayment of Senior Indebtedness, as the case may
be, to the payment of such Senior Indebtedness until all such Senior
Indebtedness shall have been paid in full, after giving effect to any concurrent
payment or distribution or provision therefor to the holders of such Senior
Indebtedness.

          4.6   Execution of Intercreditor Agreements. The Holder agrees that if
                -------------------------------------
the Company creates, incurs, or refinances any Senior Indebtedness, Holder, upon
request, will execute an intercreditor agreement with regard to the
subordination of this Note to such Senior Indebtedness in such form as may be
reasonably requested by any holder of such Senior Indebtedness who is authorized
to act on behalf of all of the holders of the particular Senior Indebtedness at
issue.

          4.7   Subrogation. Subject to the payment in full of all Senior
                -----------

holders of Senior Indebtedness to receive payments or distributions of assets of

Indebtedness shall be paid in full, and no such payments or distributions
applicable to the Senior Indebtedness shall, as between the Company, its
creditors other than the holders of Senior Indebtedness and the Holder of the
Note be deemed to be a payment by the Company to or on account of the Note, it
being understood that the provisions of Section 4 of this Note are and are
                                        ---------
intended solely for the purpose of defining the relative rights of the Holder of

Note is intended to or shall impair, as between the Company, its creditors other

obligation of the Company, which is absolute and unconditional, to pay to the
Holder of the Note the principal of and interest on the Note as and when the
same shall become due and payable in accordance with its terms, or is intended
to or shall affect the relative rights of the Holder of the Note and creditors
of the Company other than the holders of the Senior Indebtedness, nor shall
anything herein or therein prevent the Holder of the Note from exercising all
remedies otherwise permitted by applicable law upon an Event of Default under
the Note, subject to the rights, if any, under this Section 4 of the holders of
                                                    ---------
Senior Indebtedness in respect to cash, property or securities of the Company
received upon the exercise of any such remedy.

          4.8   Reliance Upon Judicial Proceeding. Upon any distribution of
                ---------------------------------
assets of the Company referred to in Section 4 of this Note, the Holder of the
                                     ---------
Note shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the liquidating
trustee or agent or other person making any distribution to the Holder of the
Note, for the purpose of ascertaining the persons entitled to participate in

Company to make, or prevent the Company from making at any time, except during
the pendency of any such dissolution, winding-up, liquidation or reorganization
proceedings or upon the maturity of the Senior Indebtedness, payments of
principal of or interest on the Note and nothing herein shall prevent the
Company from making any payments to the Holder of this Note upon subordination
with respect to the Holder's right to accelerate any or all of the principal
amount of this Note pursuant to Section 2.4 hereof.
                                -----------

          4.10  Enforcement of Subordination. The Holder of this Note, by
                ----------------------------
acceptance hereof, (a) agrees that any rights against such Holder which any

virtue of the provisions of Section 3 of this Note, may be enforced by such
                            ---------
holder of Senior Indebtedness directly against the Holder of this Note without
the necessity of joining the Company as a party, and (b) every holder of Senior
Indebtedness and every person hereafter making any advance constituting Senior
Indebtedness shall be entitled to rely upon the provisions of Section 4 of this
                                                              ---------
Note, and (c) agrees that it will join in executing such assignments, agreements
and other instruments as may be requested by any holder of Senior Indebtedness

          4.11  No Impairment by Failure to Act. No right of any present or
                -------------------------------
future holder of any Senior Indebtedness of the Company to enforce subordination
as herein provided shall at any time or in any way be prejudiced or impaired by
any failure to act on the part of the Company, or by any non-compliance by the

knowledge thereof that any such holder of Senior Indebtedness may have or be
otherwise charged with.

          4.12  Delivery of Documentation to Holders of Senior Indebtedness. The
                -----------------------------------------------------------
Holder of this Note, by acceptance hereof, authorizes and directs that a copy

by any present or future holder of Senior Indebtedness upon the subordination
provisions contained herein.

     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 One Dollar ($1.00) 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 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.

<PAGE>

         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 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.

    6.   Restriction on Transfer.

         TRANSFER, PLEDGE OR HYPOTHECATION MAY BE EFFECTED WITHOUT SUCH
         REGISTRATION AND WILL NOT BE IN VIOLATION OF APPLICABLE FEDERAL AND
         STATE SECURITIES LAWS.

          8.2  Entire Agreement. This Note supercedes all prior discussions and

agreements, between the parties with respect to the subject matter hereof and

<PAGE>

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,

               --------------
its successors and assigns and shall inure to the benefit of the Holder and his

         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.

               (a) Where the context requires: (i) use of the singular or plural
         incorporates the other, and (ii) pronouns and modifiers in the
         masculine, feminine or neuter gender shall be deemed to refer to or
         include the other genders.

               (b) As used in this Note, the terms "include[s]" and "including"
         mean "including but not limited to"; that is, in each case the example
         or enumeration which follows the use of either term is illustrative,
         but not exclusive or exhaustive.

               (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

                                       23

<PAGE>

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 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

                                       24

<PAGE>

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.

               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.

          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

           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.

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

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

                                                   -----------
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 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.

     6.   Restriction on Transfer.
          -----------------------

          THIS NOTE AND THE SECURITIES ISSUABLE UPON THE CONVERSION THEREOF HAVE
     NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
     "SECURITIES ACT"), OR UNDER ANY STATE SECURITIES LAWS AND MAY NOT BE
     OFFERED, SOLD, ASSIGNED OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED
     EXCEPT: (i) PURSUANT TO AN EFFECTIVE REGISTRATION THEREOF UNDER THE
     SECURITIES ACT; OR (ii) IF IN THE OPINION OF COUNSEL FOR THE REGISTERED
     OWNER HEREOF, WHICH OPINION IS REASONABLY SATISFACTORY TO THE COMPANY, AND
     ITS COUNSEL, THE PROPOSED OFFER, SALE, ASSIGNMENT, TRANSFER, PLEDGE OR
     HYPOTHECATION MAY BE EFFECTED WITHOUT SUCH REGISTRATION AND WILL NOT BE IN
     VIOLATION OF APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

     7.   Additional Restrictions on Transfer.

          7.1 General Prohibition Against Transfer. No party hereto, or any
              ------------------------------------

shall be void and of no effect, and the purported transferee shall be entitled
to no rights as a security holder of the Company. In addition to any other legal
or equitable remedy which may be available, the Company shall be entitled to
injunctive relief against any such noncomplying transfer by the initial Holder
or any subsequent holder. The Company shall not transfer this Note or any
portion thereof on its transfer records or recognize the purported transferee as
a holder for any purpose, including, without limitation, for purposes of payment
of principal or interest, or exercise of conversion or other rights hereunder,
unless the provisions of this Section have been complied with in full.

Company advance written notice describing the terms and conditions of the
proposed transfer and the Holder notifies the Company in writing that such a
transfer would comply with the requirements of all applicable securities laws
(accompanied by an opinion of counsel reasonably acceptable to the Company and
its counsel) and this Note, such transfer can be effected at no out-of-pocket
cost to the Company, and such transfer will not result in a material adverse
effect on the Company, the transfer restrictions of Section 7.1 and Section 7.2
                                                    -----------     -----------
shall not apply to any of the following transfers of this Note or any portion
thereof (each a "Permitted Transfer" and each recipient of said Note, a
"Permitted Transferee") by the initial Holder or by any other subsequent Holder
who has acquired this Note or any portion thereof as a Permitted Transferee (in
either case, a "Permitted Transferor"):

                  (a)  To an Affiliate of the Holder; or

                  (b)  a trust or trusts solely for the benefit of the Holder
          and/or his or her Immediate Family; or

                  (c)  a partnership or limited liability company, the partners
          or members of Holder; or

                  (d)  If the Permitted Transferor is an individual, transfers
          by gift by the Permitted Transferor, or by will or intestacy upon the
          death of the Permitted Transferor, to the spouse, children, parents or
          siblings of the Permitted Transferor or to a trust for the benefit of
          such spouse, children, parents or siblings; and

                  (e)  Transfers of the Note between the Permitted Transferor
          and the Permitted Transferor's guardian or conservator.

hereinafter referred to as a "Permitted Transferee.")

          7.4     Permitted Transfers Subject to Continuing Restrictions. The
                  ------------------------------------------------------
Note or any portion thereof transferred in any transaction described in clauses
(a) through (e) of Section 7.3 shall remain subject to the transfer restrictions
                   -----------
of Section 7.1 and Section 7.2. As a condition to a proposed Permitted Transfer,
   -----------     -----------
each Permitted Transferee shall, at the option of the Company, be required to
execute and deliver to the Company an agreement with respect to the transferred
the

                                       18

<PAGE>

Note or any portion thereof, containing all the same terms and conditions of
this Note, reflecting such Permitted Transferee's ownership of the Note or any
portion thereof so transferred, which execution and delivery shall evidence the
agreement of such Permitted Transferee that the Note or any portion thereof
intended to be transferred shall continue to be subject to the same terms and
restrictions on transfer as contained in this Note and that, as to the Note or
any portion thereof, such Permitted Transferee shall be bound by such terms and

this Note to exercise any right or power hereunder or failure by such Holder to

set forth or to exercise any rights or remedies hereunder shall not impair any
such right or power or be considered or taken as a waiver or relinquishment for

                       (a)   Where the context requires: (i) use of the singular
                  or plural incorporates the other, and (ii) pronouns and

<PAGE>

               (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

<PAGE>

          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.
