                                 PROMISSORY NOTE

                                                    Date: As of November 9, 2001

                  FOR VALUE RECEIVED, and intending to be legally bound, the
undersigned, SIMTROL, INC., by and through its duly authorized representative,
(the "Maker"), 5801 Goshen Springs Road, Norcross, Georgia 30071, promises to
pay to the order of Larry Carr, a resident of Texas, or his successors and
assigns, (the "Noteholder"), at 2619 Hemingway Drive, Arlington, Texas 76006, or
such other address in the United States as the Noteholder shall stipulate by
written notice to the Maker, on or before February 7, 2002, an amount equal to
the lesser of (A) $200,000 and (B) such lesser amount as has been advanced by
the Noteholder to the Maker and not previously repaid (such amount, the
"Principal Balance") in lawful money of the United States of America and in
immediately available funds, on the dates and in the amounts provided in this
Promissory Note (the "Note"). The debt represented by this Note shall be
pursuant to advances made, from time to time, by the Noteholder to the Maker.

                  CONSIDERATION. For every $1.00 in principal advanced under the
Note, the Noteholder shall receive a warrant from the Maker entitling the
Noteholder to purchase a share of common stock, par value $.001 per share (the
"Common Stock"), of the Maker. Each warrant shall be dated as of the date of the
corresponding advance of principal under the Note (the "Warrant Date") and the
purchase price per share of the Common Stock under such warrant shall be equal
to the lesser of the price quoted for the Common Stock at the close of business
on the Warrant Date or the five day average stock price for the Common Stock at
the close of business on the five days immediately preceding such advance.

         SECTION 1. PAYMENT TERMS.

         (A)      INTEREST. Interest on the principal advanced to the Maker
shall commence as of the date of the advance and shall accrue until the maturity
date of February 7, 2002 (such period of time, the "Term") on the Principal
Balance at a rate equal to the Prime Rate plus 1%. Interest shall accrue daily
on the Principal Balance throughout the Term, and the Principal Balance and all
interest accrued thereon shall be paid at the expiration of the Term. For
purposes of this Note, the term "Prime Rate" shall mean the average of the prime
rates quoted daily in The Wall Street Journal during the Term of the Note. (When
the daily prime rate is quoted as a range, we will use an average of the high
and low rates in calculating the prime rate for that day.) Interest shall be
computed for the actual number of days elapsed on the basis of a year consisting
of 365 days.

         (B)      PAYMENT. Payment of the Principal Balance plus all accrued
interest thereon shall be due and payable on February 7, 2002. In the event that
this Note must be extended by the Maker, the Maker shall issue to the Noteholder
warrants to purchase the common stock of the Maker as set forth below:
<PAGE>

                  1.       For the first sixty-day (60) extension each
                           Noteholder shall receive 100,000 warrants.
                  2.       For the second sixty-day (60) extension each
                           Noteholder shall receive 50,000 warrants.
                  3.       For any additional sixty-day (60) extensions each
                           Noteholder shall receive 50,000 warrants.

The above warrants shall be priced at $0.49 per warrant.

         (C)      PREPAYMENTS. The Maker shall have the right to prepay all or
any part of this Note without penalty. Any amount prepaid shall not be eligible
to be readvanced under this Note.

         (D)      NO SET-OFFS. Payment is to be made absolutely and
unconditionally, without defenses, set-offs, or claims or counterclaims of any
kind whatsoever.

         (E)      COLLATERAL. The Maker shall pledge all of its receivables,
securities, inventory, and patents to the Noteholder and deliver to the
Noteholder all necessary and appropriate collateral documents, including but not
limited to security agreements, pledge agreements, UCC-1s, and shall file such
documents as necessary to perfect such security interests. In the event that the
maker fails to execute, file or deliver these documents or collateral, however,
it is still the intention of the Maker to pledge such assets to the Noteholder.

         (F)      RIGHT TO CONVERT. At any time prior to the full repayment of
any amount to the Noteholder, the Noteholder shall have the right to convert
this promissory note and any interest due into shares of the common stock at a
price of $0.49 per share.

         SECTION 2. DEFAULT.

         (A)      REMEDIES AND EVENTS OF DEFAULT. The Maker shall be in default
hereunder, and the entire unpaid Principal Balance, shall be immediately due and
payable at the option of the Noteholder, upon the occurrence of any of the
following events: (a) the making of an assignment by the Maker for the benefit
of creditors or the commencement of a case by or against the Maker under any
bankruptcy, rehabilitation, debt adjustment, liquidation or receivership law
(state or federal); (b) the entry of any judgment against the Maker or the
issuing of any attachment or garnishment against any property of the Maker; or
(c) any default in the payment of the Principal Balance when same is due and
payable hereunder. Such right is in addition to all other rights and remedies at
law or in equity, all rights and remedies available to a noteholder under the

any other agreement executed in connection with this transaction that may be
available to Noteholder.

         (B)      ATTORNEYS FEES. The Maker hereby agrees to pay all expenses
incurred, including reasonable attorneys' fees and disbursements, incurred by
Noteholder if this Note is placed in the hands of an attorney for collection
(whether or not by way of litigation) or if collected through probate,
bankruptcy or other judicial proceedings.

         (C)      INTEREST AT DEFAULT. If any payment hereunder is not made when
due, such amount shall bear interest until paid at an annual rate of interest
equal to twenty-four percent (24%) unless such rate exceeds the maximum interest
rate permitted under the State of Texas law, in which case such amount shall
bear interest until paid at a rate equal to such maximum rate permitted under
State of Texas law.

         (D)      CONFESSION OF JUDGMENT. At any time after default by the Maker
hereunder, the Maker hereby constitutes, appoints, authorizes and empowers the
Clerk of any court, or any attorney-at-law whom Noteholder may designate, to
appear for the Maker in any court having competent jurisdiction in one or more
proceedings, or before any Clerk thereof, and to confess judgment in favor of
Noteholder against the Maker without prior notice or opportunity for prior
hearing, for the unpaid balance of principal due hereunder plus accrued interest
thereon, if any, and the cost of suit and an attorneys' fee equal to fifteen
percent (15%) of such unpaid amount, hereby ratifying and confirming any and all
acts and things that the Clerk of the court or said attorney, or both, may do
that are necessary and convenient to a valid confession of judgment whether it
was under the jurisdiction of said court or not, hereby waiving and releasing,
to the fullest extent permitted by law, all errors and all rights of exemption,
appeal, stay of execution, inquisition and extension under levy upon real estate
or personal property to which the Maker may otherwise be entitled under the laws
of the United States or any state or possession of the United States now in
force or which may hereafter be enacted. The authority and power to appear for
and enter judgment against the Maker shall not be exhausted by one or more
exercises thereof, or by any imperfect exercise thereof, and shall not be
extinguished by any judgment entered pursuant thereto. Such authority and power
may be exercised on one or more occasions, from time to time, in the same or
different jurisdictions, as often as the Noteholder shall deem necessary or
desirable, for all of which this Note shall be deemed sufficient warrant.

         SECTION 3. BUSINESS PURPOSE. The Maker expressly warrants and
represents that the indebtedness hereby evidenced has been incurred for the
purpose of carrying on a business, professional or commercial activity and that
no portion of the proceeds of the loan hereby evidenced shall be used to
purchase consumer goods. Notwithstanding anything to the contrary, under no
circumstances will interest accrue or be payable at a rate in excess of the

                  FOR VALUE RECEIVED, and intending to be legally bound, the
undersigned, SIMTROL, INC., by and through its duly authorized representative,
(the "Maker"), 5801 Goshen Springs Road, Norcross, Georgia 30071, promises to
pay to the order of Edward S. Redstone, a resident of Massachusetts, or his
successors and assigns, (the "Noteholder"), at 222 Merrimack Street, Suite 210,

Noteholder shall stipulate by written notice to the Maker, on or before February
7, 2002, an amount equal to the lesser of (A) $200,000 and (B) such lesser

States of America and in immediately available funds, on the dates and in the
amounts provided in this Promissory Note (the "Note"). The debt represented by
this Note shall be pursuant to advances made, from time to time, by the

         CONSIDERATION. For every $1.00 in principal advanced under the Note,

shall commence as of the date of the advance and shall accrue until the maturity
date of February 7, 2002 (such period of time, the "Term") on the Principal

purposes of this Note, the term "Prime Rate" shall mean the average of the prime
rates quoted daily in The Wall Street Journal during the Term of the Note. (When
the daily prime rate is quoted as a range, we will use an average of the high

computed for the actual number of days elapsed on the basis of a year consisting
of 365 days.

         (B)      PAYMENT. Payment of the Principal Balance plus all accrued
interest thereon shall be due and payable on February 7, 2002. In the event that

Noteholder all necessary and appropriate collateral documents, including but not

documents as necessary to perfect such security interests. In the event that the
maker fails to execute, file or deliver these documents or collateral, however,
it is still the intention of the Maker to pledge such assets to the Noteholder.

         (F)      RIGHT TO CONVERT. At any time prior to the full repayment of

rate permitted under Commonwealth of Massachusetts law, in which case such
amount shall bear interest until paid at a rate equal to such maximum rate
permitted under Commonwealth of Massachusetts law.

         (D)      CONFESSION OF JUDGMENT. At any time after default by the Maker
hereunder, the Maker hereby constitutes, appoints, authorizes and empowers the
