                               PROMISSORY NOTE

$975,000.00                     DALLAS, TEXAS                 September 24, 1997

         1.       PROMISE TO PAY. FOR VALUE RECEIVED, the undersigned,
BODYBILT, INC., a Texas corporation (formerly known as BodyBilt Seating, Inc)
("Maker"), hereby promises to pay to the order of COMERICA BANK - TEXAS
("Payee"), at its offices at 1601 Elm Street, Dallas, Texas 75201, or such
other location as Payee may hereafter designate in writing, in lawful money of
the United States of America the principal sum of NINE HUNDRED SEVENTY-FIVE
THOUSAND AND NO/1OO DOLLARS ($975,000.00), together with interest on the unpaid
principal balance outstanding from time to time hereon from day to day at the
annual rate set forth below.

         2.      INTEREST RATE. The unpaid principal balance of this Note shall
accrue interest prior to maturity or default at a rate equal to the lesser of
(a) 9.20% per annum (the "Applicable Rate") or (b) the Maximum Rate
(hereinafter defined).

         "Maximum Rate" means the maximum" lawful rate of interest permitted by
applicable usury laws now or hereafter enacted which interest rate shall change
when and as said laws change, to the extent permitted by law, effective on the
day such change in said laws becomes effective.

         In determining the Maximum Rate, due regard shall be given to all
payments, fees, charges, deposits, balances and agreements which may constitute
interest or be deducted from principal when calculating interest.  Computations
of interest on the unpaid principal balance of this Note, from time to time
outstanding, at the rate provided in this Note, shall be made on the basis of
the actual number of days elapsed.  To the extent permitted by applicable law,
such interest shall be computed as if each year consisted of three hundred
sixty (360) days, but to the extent such computation of interest might cause
the rate of interest to exceed the Maximum Rate, such interest shall be
computed on the basis of a three hundred sixty-five (365) day or three hundred
sixty-six (366) day year, as the case may be.

         3.      PAYMENT. This Note is and shall be due and payable in sixty
(60) monthly installments.  The first fifty-nine (59) installments are and
shall be in the amount of $10,005.44 including accrued interest each, and the
sixtieth (60th) and final installment is and shall be in an amount equal to the
balance of principal and accrued and unpaid interest then owing hereon.  The
first (1st) installment is and shall be due and payable on November 1, 1997,
and the remaining installments are and shall be due and payable in consecutive
order on the first (1st) day of each and every succeeding calendar month
thereafter until all amounts called for hereunder have been paid in full, with
the final installment being due and payable on October 1, 2002.

         All principal, interest and other sums payable under this Note shall
be paid, not later than 2:00 o'clock p.m.  (Dallas, Texas time) on the day when
due, in immediately available funds in lawful money of the United States of
America.  Any payment under this Note or under any other Loan Document (as
hereinafter defined) other than in the required amount in good, unrestricted
U.S. funds




PROMISSORY NOTE - PAGE 1
<PAGE>   2
immediately available to the Payee shall not, regardless of any receipt or
credit issued therefor, constitute payment until the required amount is
actually received by the Payee hereof in such funds and shall be made and
accepted subject to the condition that any check or draft may be handled for
collection in accordance with the practice of the collecting bank or banks.

         4.      EFFECT OF WEEKEND AND HOLIDAYS.  If any installment of
principal or interest on this Note shall become due on a Saturday, Sunday or
any other day on which Payee is not open for business, such payment shall be
made on the next succeeding day on which Payee is open for business; and such
extension of time shall in such case be included in computing interest in
connection with such payment.

         5.      DEFAULT INTEREST RATE.  All past due principal and interest on
this Note, whether due as the result of acceleration of maturity or otherwise,
shall bear interest at the Maximum Rate. In determining the maximum rate, due
regard shall be given to all payments, fees, charges, deposits, balances and
agreements which may constitute interest or be deducted from principal when
calculating interest.

         6.      PREPAYMENTS.  On any interest payment date under this Note,
and upon five (5) days written notice to Payee, Maker may prepay this Note in
whole or in part in amounts of at least Fifty Thousand and No/100 Dollars
($50,000.00) upon payment to Payee of a premium (not to be applied to principal
or interest) in an amount equal to the sum of the discounted net present values
of the interest payments that would otherwise be payable on the principal
amount being prepaid after reducing each such interest payment by the amount of
interest that would be payable on its respective due date if the amount being
prepaid were reinvested at the Current Market Rate.  For these purposes,
"Current Market Rate" shall mean a per annum interest rate equal to one-half
percent (1/2%) above the rate reasonably determined by Payee (based on
quotations from established dealers) to be in effect at the prepayment date in
the secondary market for United States Treasury Securities of a comparable
amount and with a comparable term to maturity.  The discount rate for the above
computation shall be the Current Market Rate.  A certificate shall be submitted
by Payee to Maker computing the prepayment premium and shall be presumed
correct absent manifest error.

         The provisions of this Paragraph shall be subject to Paragraph 8 of
this Note so that to the extent the prepayment premium is considered interest
under applicable law, the provisions of such Paragraph 8 shall apply.

         7.      SECURITY FOR NOTE.  This Note is secured, among other things,
by a Deed of Trust, Assignment, Security Agreement and Financing Statement
(herein called the "Deed of Trust") of even date herewith, pursuant to which
the Maker, conveyed to Gary W. Orr, as Trustee, certain property in Grimes
County, Texas, fully described therein (the "Property ).Payment of this Note is
unconditionally guaranteed by ErgoBilt, Inc., a Texas corporation.

         This Note, the Deed of Trust, the Guaranty Agreement and any other
document now or hereafter securing, guaranteeing or executed in connection with
the loan evidenced by this Note are, as the same may be amended, restated,
modified or supplemented from time to time herein sometimes called individually
a "Loan Document" and together the "Loan Documents".

         8.      DEFAULT.  If Maker fails to make any payment on this Note
either principal, interest or any installment thereof when due, or if default
occurs under the Deed of Trust or under any other Loan Document and such
default continues following the expiration of any applicable curative period,
then in any such event the Payee may, at its option, without notice or demand,
declare the entire unpaid principal balance of and accrued but unpaid interest
on the indebtedness evidenced by this Note immediately due and payable without
notice or demand, foreclose all liens and security interests securing the
payment hereof, offset against this Note any sum or sums owed by the Payee to
Maker (including any deposits, funds or other property of Maker held by Payee),
and/or exercise any or all other remedies available to the Payee, all at the
option of the Payee.  Failure to exercise any such option shall not constitute
a waiver of the right of Payee to exercise the same at any later time or in the
event of any subsequent default.  The acceptance by Payee of any payment
hereunder that is less than payment in full of all amounts due and payable at
the time of such payment shall not constitute a waiver of the right to exercise
any of the foregoing options at that time, or at any subsequent time, or
nullify any prior exercise of any such option, without the express written
consent of Payee.

         9.      USURY LIMITATIONS.  It is the intent of Payee and Maker in the
execution of this Note and all other Loan Documents to contract in strict
compliance with applicable usury law.  In furtherance thereof, Payee and Maker
stipulate and agree that none of the terms and provisions contained herein or
in any other Loan Document shall ever be construed to create a contract to pay,
for the use, forbearance or detention of money, interest at a rate in excess of
the Maximum Rate.  Neither Maker nor any co-makers, endorsers, sureties,
guarantors or other parties now or hereafter becoming liable for payment of
this Note shall ever be required to pay interest or finance charges at a rate
in excess of the Maximum Rate, and the provisions of this Paragraph shall
control over all other provisions of this Note and any other Loan Document
which may be in apparent conflict herewith.  Payee and any other holder of this
Note expressly disavow any intention to charge or collect excessive unearned
interest or finance charges in the event the maturity of this Note is
accelerated.  If demand is made or if the maturity of this Note shall be
accelerated for any reason or if any of the principal of this Note is prepaid,
and as a result thereof the interest or finance charge received for the actual
period of existence of the loan evidenced by this Note exceeds the Maximum
Rate, the holder of this Note shall, at its option, either refund to Maker the
amount of such excess or credit the amount of such excess against the principal
balance of this Note then outstanding, and thereby shall render inapplicable
any and all penalties of any kind provided by applicable law as a result of
such excess interest.  In the event that Payee or any other holder of this Note
shall collect monies and/or any other thing of value which are deemed to
constitute interest which would increase the effective interest rate on this
Note to a rate in excess of the Maximum Rate, all such sums deemed to
constitute interest in excess of the lawful rate shall, upon such
determination, at the option of the holder of this Note, be either immediately
returned to Maker or credited against the principal balance of this Note then
outstanding, in which event any and all penalties of any kind under



PROMISSORY NOTE - PAGE 3
<PAGE>   4
applicable law as a result of such excess interest shall be inapplicable.  In
determining whether or not the interest paid or payable, under any specific
circumstance, exceeds the maximum amount permitted under applicable law, Payee
and Maker shall to the greatest extent permitted by applicable law, (i)
characterize any non-principal payment as an expense, fee or premium rather
than as interest, (ii) exclude voluntary prepayments and the effects thereof,
and (iii) amortize, prorate, allocate and spread the total amount of interest
throughout the entire contemplated term hereof in accordance with the amounts
outstanding from time to time thereunder and the Maximum Rate from time to time
in effect under applicable law in order to lawfully charge the maximum amount
of interest permitted under applicable law.  By execution of this Note, Maker
acknowledges that it believes the loan evidenced hereby to be nonusurious and
agrees that if, at any time, Maker should have reason to believe that this Note
is in fact usurious, it will give the holder of this Note notice of such
condition and Maker agrees that said holder shall have ninety (90) days in
which to make appropriate refund or other adjustment in order to correct such
condition if in fact such exists.  The term "applicable law" as used in this
Note shall mean the laws of the State of Texas or the laws of the United
States, whichever laws allow the greater rate of interest, as such laws now
exist or may be changed or amended or come into effect in the future.

         The terms "Maximum Amount" or "Maximum Rate" as used herein include,
as to Article 5069-1.04 of the Revised Civil Statutes of the State of Texas
(and as same may be incorporated by reference in other statutes of the State of
Texas), but otherwise without limitation, that rate based upon the "Indicated
(Weekly) Rate Ceiling"; provided, however, that this designation shall not
preclude the rate of interest contracted for, charged or received hereunder or
otherwise in connection with this loan transaction from being governed by, or
construed in accordance with, any other state or federal law, and Payee has the
right from time to time to implement, withdraw, and reinstate any ceiling as an
alternative to the Indicated (Weekly) Rate Ceiling, including the right to
reinstate the Indicated (Weekly) Rate Ceiling.

         10.     WAIVERS.  Maker and any sureties, guarantors, endorsers and
all other parties ever liable for payment of this Note jointly and severally
(a) waive demand, notice of intent to demand, presentment, notice of
nonpayment, notice of intent to accelerate, notice of acceleration, diligence
in collecting, grace, protest, notice of protest, notice of dishonor, notice of
application for or actual appointment of a receiver for the Property or any
other asset of Maker, bringing of suit, and diligence in taking any action to
collect any sums owing hereunder or in proceeding against any of the rights and
properties securing payment of the indebtedness evidenced by this Note, (b)
consent to all extensions without notice for any period or periods of time and
partial payments, before or after maturity, without prejudice to the Payee; (c)
agree to any substitution, subordination, exchange or release of any such
security or the release of any party primarily or secondarily liable hereon;
(d) agree that Payee shall not be required first to institute suit or exhaust
its remedies hereon against Maker or others liable or to become liable hereon
or to enforce its rights against them or any security here for; and (e) consent
to any extension or postponement of time of payment of this Note or to any
other indulgence with respect hereto without notice to any of them, and without
in any way affecting the personal liability of any party hereunder.

         11.     COLLECTION COSTS.  If Payee retains an attorney in connection
with any default or at maturity or to collect, enforce or defend this Note or
any other Loan Document in any lawsuit or in probate, reorganization,
bankruptcy or other proceeding, then Maker agrees to pay to Payee, in addition
to principal and interest, all reasonable costs and expenses incurred by Payee
