         Coach and Car may transfer this Note, and Coach and Car or anyone who
takes this Note by transfer and who is entitled to receive payments under this
Note is called the "Noteholder."

         2. Interest.

         Interest will be charged on the unpaid principal until the full amount
is paid. Maker will pay interest at an annual rate of eight and one-half percent
(8-1/2%), compounded annually. Interest shall be calculated on the basis of a
360-day year and shall be computed on the actual number of days elapsed.

         3. Payments.

         3.1 Interest for the first year of the Note will be added to the
principal. Maker will make an initial payment of accrued interest on April 1,
2001. Thereafter, Maker will make semi-annual payments of accrued interest on
March 31 and September 30 of each year until the Maturity Date, as defined in
Section 4. On the Maturity Date, Maker will pay all principal and accrued
interest.

         3.2 All payments hereunder shall be in accordance with the amortization
schedule attached hereto as Attachment A.

         3.3 Maker shall have the right to prepay this Note in full or in part
without penalty.

         4. Maturity.

         Maker's obligations under the Note shall become fully due and payable
on October 15, 2004 (the "Maturity Date"). In the event Maker directly or
through its Affiliates (hereafter
<PAGE>   2
defined) completes a private or public offering of debt or equity securities
before the Maturity Date, the proceeds of such offering shall be first applied
to repayment of the Note thereby accelerating the Maturity Date, subject only to
an Underwriting Limitation, as defined below. The term "Underwriting Limitation"
shall mean the following: (i) any reasonable and customary indebtedness
repayment limitation imposed on such proceeds by an underwriter pursuant to an
underwriting agreement; or (ii) in the event of a private offering with no
underwriter, an indebtedness repayment limitation imposed on offering proceeds
to which the Noteholder consents; provided however that the consent of the
Noteholder shall not be required on the first Two Million Dollars ($2,000,000)
cumulative offering proceeds obtained in the aggregate by Maker and its
Affiliates after the date of this Note. In the event that the proceeds applied
against this Note from any offering of securities is not sufficient to retire
the Note, then the proceeds of any subsequent offering shall be first applied to
repayment of the Note subject to an Underwriting Limitation. Subject to an
Underwriting Limitation, by its terms, any such offering will designate as part
of the use of proceeds the repayment of indebtedness represented by this Note,
and such repayment shall have priority over other applications of the proceeds.
In the event of any offering, the proceeds of such offering to be applied
against the Note shall be so applied within ten (10) days of Closing and the
funding of the offering. As used herein, Affiliates shall mean any corporation
controlling Maker or under the control of Maker or any corporation in which any
shareholder of Maker owns twenty percent (20%) or more of the outstanding common
stock, including but not limited to Beacon Industries, Inc.

         5. Note Charges.

         If a law which applies to this Note and which sets maximum loan charges
is finally interpreted so that the interest or other charges collected or to be
collected in connection with this Note exceed the permitted limits, then: (i)
any such Note charges shall be reduced by the amount necessary to reduce the
charge to the permitted limit; and (ii) any sums already collected from Maker
which exceeded permitted limits will be refunded to Maker. The Noteholder may
choose to make this refund by reducing the principal it owes under this Note or
by making a direct payment to Maker. If a refund reduces principal the reduction
will be treated as a partial prepayment.

         6. No Waiver, Expenses.

         6.1 Even if at a time when Maker is in default Noteholder does not
require Maker to pay immediately in full as directed below, Noteholder will
still have the right to do so if Maker is in default at a later time.

         6.3 Presentment, demand, protest, notices of protest, dishonor and
non-payment of this Note and all notices of every kind except notices of payment
changes are hereby waived.

security. No delay or omission on the part of the Noteholder in exercising any
right under this Note shall operate as a waiver of such right or of any other
right under this Note. The release of any party liable on this Note shall not
operate to release any other party liable on the Note.
