                                 PROMISSORY NOTE

$20,000                                                           June 28, 2002

     FOR  VALUE  RECEIVED,  the  undersigned,   Perma-Tune   Electronics,   Inc.
("Maker"),  hereby  promises  to pay to the  order of Linda  Decker  and  Lonnie
Lenarduzzi  ("Payee"),  the principal sum of Twenty  Thousand and no/100 Dollars
($20,000),  in lawful  money in United  States of America,  which shall be legal
tender,  in payment of all debts and dues,  public and  private,  at the time of
payment, bearing interest and payable as provided herein.

     Interest  on the unpaid  balance  of this Note  shall  accrue at a rate per
annum equal to 10%; provided,  however,  that such interest shall not exceed the
Maximum Rate as hereinafter  defined.  All past-due principal and interest shall
bear interest at the maximum rate permitted by applicable law.  Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

     The  principal  amount and  accrued  interest of this Note shall be due and
payable on June 28,  2004.  The Note may be renewed  for  additional  thirty-day
periods at the option of the holder.

     This Note may be prepaid in whole or in part,  at any time and from time to
time, without premium or penalty.

     If any payment of  principal or interest on this Note shall become due on a
Saturday,  Sunday  or any  other  day on which  national  banks are not open for
business, such payment shall be made on the next succeeding business day.

<PAGE>


     This Note shall be binding upon and inure to the benefit of the Payee named
herein and Payees respective  successors and assigns.  Each holder of this Note,
by accepting the same,  agrees to and shall be bound by all of the provisions of
this  Note.  Payee may  assign  this  Note or any of its  rights,  interests  or
obligations to this Note without the prior written approval of Maker.

     The  indebtedness  evidenced by this Note is unsecured and  subordinate and
junior  in  right  of  payment  to the  prior  payment  in  full  of all  senior
indebtedness (however defined in any debt instrument).

     Notwithstanding  anything  to the  contrary  in  this  Note  or  any  other
agreement entered into in connection herewith, whether now existing or hereafter
arising and whether  written or oral,  it is agreed  that the  aggregate  of all
interest  and  any  other  charges  constituting  interest,  or  adjudicated  as
constituting  interest,  and contracted for, chargeable or receivable under this
Note or  otherwise  in  connection  with this loan  transaction,  shall under no
circumstances exceed the Maximum Rate. In the event the maturity of this Note is
accelerated  by reason of an Event of Default under this Note,  other  agreement
entered into in  connection  herewith or therewith,  by voluntary  prepayment by
Maker or otherwise, then earned interest may never include more than the Maximum
Rate,  computed from the dates of each advance of the loan proceeds  outstanding
until  payment.  If from any  circumstance  any  holder of this Note  shall ever
receive interest or any other charges constituting  interest,  or adjudicated as
constituting  interest,  the amount, if any, which would exceed the Maximum Rate
shall be applied to the  reduction of the  principal  amount owing on this Note,
and not to the payment of interest;  or if such excessive  interest  exceeds the
unpaid balance of principal hereof,  the amount of such excessive  interest that
exceeds the unpaid  balance of principal  hereof shall be refunded to Maker.  In
determining  whether or not the  interest  paid or payable  exceeds  the Maximum
Rate, to the extent  permitted by applicable  law (i) any  nonprincipal  payment
shall be  characterized  as an expense,  fee or premium rather than as interest;
and (ii) all interest at any time contracted for, charged, received or preserved
in connection  herewith  shall be amortized,  prorated,  allocated and spread in
equal parts  during the period of the full  stated  term of this Note.  The term
"Maximum  Rate" shall mean the maximum  rate of interest  allowed by  applicable
federal or state law.

     Except as provided herein, Maker and any sureties, guarantors and endorsers
of this  Note  jointly  and  severally  waive  demand,  presentment,  notice  of
nonpayment or dishonor, notice of intent to accelerate,  notice of acceleration,
diligence  in  collecting,  grace,  notice  and  protest,  and  consent  to  all
extensions  without  notice  for any  period  or  periods  of time  and  partial
payments, before or after maturity,  without prejudice to the holder. The holder
shall similarly have the right to deal in any way, at any time, with one or more
of the foregoing  parties  without  notice to any other party,  and to grant any
such party any extensions of time for payment of any of said indebtedness, or to
grant any other  indulgences  or forbearance  whatsoever,  without notice to any
other party and without in any way affecting the personal liability of any party
hereunder.  If any  efforts  are made to  collect  or  enforce  this Note or any
installment due hereunder,  the undersigned  agrees to pay all collection  costs
and fees, including reasonable attorney's fees.
<PAGE>

     This Note shall be construed and enforced under and in accordance  with the
laws of the State of Texas.

     IN WITNESS  WHEREOF,  Maker has duly  executed  this Note as of the day and
year first above written.
