         FOR VALUE RECEIVED, Imperial Industries, Inc, a Delaware corporation,
("Maker"), hereby promises to pay to the order of Imperial Settlement LLC
("Payee"), the principal sum of Eight Hundred Eleven Thousand Dollars
($811,000.00) in lawful money of the United States of America, together with
interest accruing (i) from the date of this Promissory Note through November 1,
2004 at the rate of Five and Sixth/Tenths percent (5.60%), and (ii) from
November 1, 2004 through May 1, 2006 at a rate of Eight percent (8.00%), on the
terms set forth herein as follows:

         1. Principal and interest on this Promissory Note shall be due and
payable by Maker to Payee as follows:

                  (a) Subject to the right of prepayment in section 2, payments
         of accrued interest only shall be due and payable in the amount of
         Twenty-Two Thousand Seven Hundred Eight Dollars ($22,708.00)
         semi-annually on November 1 and May 1 each year commencing on November
         1, 2003 through November 1, 2004 and, in the amount of Thirty-Two
         Thousand Four Hundred Forty Dollars ($32,440.00) semi-annually on May 1
         and November 1 of each year commencing May 1, 2005 and a final payment
         of principal and accrued interest in the amount of Eight Hundred
         Forty-Three Thousand Four Hundred Forty-Four Dollars ($843,440.00)
         shall be due on May 1, 2006. Under no circumstances will the interest
         rate on this Promissory Note be more than the maximum rate allowed by
         applicable law.

                  (b) Interest on the Promissory Note shall be computed on the
         basis of an 360-day year comprised of 30-day months provided that for
         interest due and payable any day other than a semi-annual payment date,
         interest shall be computed on the basis of a 360-day year and the
         actual number of days elapsed. If a due date for the payment of
         principal or of interest on this Promissory Note falls on a Saturday,
         Sunday or legal holiday, such payment shall be due on the next
         succeeding banking day.

                  (c) Any sums payable hereunder shall be applied first to cure
         any default hereunder (including payment of all costs and expenses),
         second to interest, and third to reduction of principal. Any payment
         made following the due date shall be payable with interest on the
         amount of such payment attributable from the due date at the Default
         Rate, as hereinafter defined.

         2. This Promissory Note may be prepaid, without penalty at any time
during the term hereof, at the option of Maker. All sums received as a
prepayment, after first being applied to any expense and accrued interest due to
Payee hereunder shall be applied to reduce the principal becoming due hereunder.
In the event Maker prepays this Promissory Note in full but not part on or prior
to November 1, 2004, the amount of principal due hereunder shall be reduced from
$811,000.00 to $567,700.00.

         3. Payments not made within fifteen (15) days of the due date under the
terms of this Promissory Note, shall be subject to a late charge of Five percent

costs of suit and other reasonable expense in connection therewith, including
reasonable attorney's fees. In addition, notwithstanding anything herein to the
contrary, upon an Event of Default, the rate of interest hereunder shall
automatically accrue at fifteen percent (15%) (the "Default Rate"), which
Default Rate shall commence on the date of the Event of Default and continue
until the earlier of the cure of such default or payment in full hereunder.

         8. The rights and remedies of Payee as provided herein or otherwise
shall be cumulative and concurrent, and may be pursued singly, successively or
together at the sole discretion of Payee, and may be exercised as often as
occasion therefor shall occur, and, to the maximum extent permitted by
applicable law, the failure to exercise any such right or remedy shall in no
event be construed as a waiver or release thereof.

law, presentment for payment, demand, notice of demand, notice of nonpayment or
dishonor, protest and notice of protest of this Promissory Note, and Maker

waivers or modifications that may be granted by Payee with respect to the

have waived any of its rights or remedies hereunder unless such waiver is in
writing and signed by Payee, and then only to the extent specifically set forth
in the writing. A waiver of one (1) event shall not be construed as continuing
or as a bar to or waiver of any right or remedy as to a subsequent event.

                                       3

(as co-borrowers, collectively referred to herein as "Borrower" or "Borrowers").
As used herein, all capitalized terms not defined herein shall have the

and

WHEREAS, Lender is willing to so modify the terms applicable to such loans and

NOW, THEREFORE, in consideration of the mutual conditions and agreements set

sufficiency of which is hereby acknowledged, the parties hereto agree as

     1.   By mutual agreement, sections 1.13, 2.1(a)(ii), and 9.10(g) of the

          day for Lender's examiners in the field and office;

<PAGE>

     2.   Conditions Precedent.

          Each of the following is a condition precedent to any obligation of
          Lender to extend Loans in excess of the amounts permitted under the
          Loan Agreement prior to this Amendment:

               A. All requisite corporate action and proceedings in connection
          with this Amendment and the other Financing Agreements shall be
          satisfactory in form and substance to the Lender, and Lender shall
          have received all information, and copies of all documents, including
          records of requisite corporate actions and proceedings, which Lender
          may have requested in connection therewith, in form and substance
          satisfactory to Lender and its counsel;

               B. This Amendment and all other Financing Agreements contemplated
          to be delivered in connection herewith shall have been duly executed
          and delivered to Lender, in form and substance satisfactory to Lender.

     3.   Borrowers shall pay to Lender at closing of this Amendment a closing
          fee in the amount of $20,000, which fee shall be due and payable, and
          deemed to have been fully earned, on the date of this Amendment,
          irrespective of any actual funding under the Loan Agreement.

     4.   Each Borrower certifies to Lender that (a) (after giving effect to
          this Amendment) all representations and warranties of such Borrower
          contained in the Loan Agreement are true and correct as of the date of
          this Amendment, except to the extent such representations and
          warranties relate solely to an earlier date; (b) no Event of Default
          under the Loan Agreement, or event which with the passage of time or
          the giving of notice, or both, would constitute an Event of Default
          under the Loan Agreement, has occurred and is continuing; and (c) no
          changes have been made to its organizational documents, including its
          articles or certificate of incorporation or organization and its
          bylaws since the date of its delivery to Lender thereof in connection
          with the Loan Agreement prior to the date of this Amendment. The
          Borrowers acknowledge and agree that Inventory at locations as to
          which all actions required to be taken pursuant to Section 9.2 have
          not been taken shall constitute Collateral, but, at the option of
          Lender, shall not be deemed to be Eligible Inventory unless and until
          such requirements are satisfied, which requirements shall include
          UCC-11 searches, opinions of counsel and the filing of appropriate
          Form UCC-1 Financing Statements.

     5.   In no way in limitation of the provisions of Section 9.10 of the Loan
          Agreement, Borrower will pay all out-of-pocket expenses incurred by
          Lender in connection with the preparation of this Amendment and of the
          other Financing Agreements, including, all amendments, supplements or
          modifications hereafter made to any of the foregoing after the date of
          this Amendment, and the closing of the transactions contemplated
          herein and therein, including, but not limited to, the reasonable fees
          and expenses of counsel for Lender. In addition, Borrower agrees to
          pay, and hereby indemnifies Lender for and holds Lender harmless from
          and against, all costs, interest, penalties, and other amounts arising
          out of or in connection with all documentary stamp taxes, intangible
          taxes, filing or recording fees required in connection with the
          transactions hereunder. This provision shall survive payment of the
          Obligations and termination of the Financing Agreements.

                                       2
<PAGE>

     6.   EACH BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES
          ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
          ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AMENDMENT, THE LOAN
          AGREEMENT, ALL DOCUMENTS AT ANY TIME MADE IN CONNECTION WITH THIS
          AMENDMENT, THE LOAN AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED HEREIN
          OR THEREIN. FURTHER, EACH BORROWER HEREBY CERTIFIES THAT NO
          REPRESENTATIVE OR AGENT OF THE LENDER NOR THE LENDER'S COUNSEL HAS
          REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE LENDER WOULD NOT, IN THE
          EVENT OF SUCH LITIGATION, SEEK TO ENFORCE THIS WAIVER OF RIGHT TO JURY
          TRIAL PROVISION. FINALLY, EACH BORROWER ACKNOWLEDGES THAT THE LENDER
          HAS BEEN INDUCED TO ENTER INTO THIS AMENDMENT BY, INTER ALIA, THE
          PROVISIONS OF THIS PARAGRAPH.

     7.   Each Borrower agrees that it has no off-sets, defenses or
          counterclaims to the payment of the Obligations or the performance by
          it under the Loan Agreement or the other Financing Agreements.
          Further, each Borrower agrees that it has no claims of any nature
          whatsoever against the Lender, its parent, subsidiaries, affiliates,
          divisions, officers, directors, employees, agents, stockholders,
          successors, or assigns arising out of or related to the Obligations,
          the Financing Agreements, or otherwise.

     8.   Borrowers each acknowledge and confirm that all Collateral furnished
          in connection with the Loan Agreement continues to secure the
          Obligations, as hereby modified. Each of the Borrowers hereby grants
          and regrants, as applicable, the Lender all liens, security interests,
          assignments, and rights of setoff in and to the Collateral to secure
          all Obligations.

     9.   Any breach of the terms of this Amendment shall, at the option of
          Lender, constitute an Event of Default, entitling Lender to exercise
          its rights and remedies under the Financing Agreements.

     10.  Except as amended by this Amendment, the Loan Agreement (as in effect
          immediately prior to the effectiveness of this Amendment) and all
          other Financing Agreements shall remain in full force and effect.

          herein shall be binding upon and inure to the benefit of the parties
          hereto, their respective successors and assigns, except that Borrowers
          shall not have the right to assign their rights hereunder or any
          interest herein without the prior written consent of Lender.
