                                                         TAX I.D. NO. 36-3635935

                                PROMISSORY NOTE

$5,000,000.00                                     Detroit, Michigan
                                                  June 30, 1995

         On or before June 30, 1996, FOR VALUE RECEIVED, the undersigned,
SCOTSMAN GROUP INC., a Delaware corporation (herein called "Maker") promises to
pay to the order of COMERICA BANK-ILLINOIS, an Illinois banking corporation
(herein called "Bank"), at the principal office of Bank at Franklin Park,
Illinois, in lawful currency of the United States of America, FIVE MILLION
DOLLARS ($5,000,000.00) or so much of said sum as has been advanced and is then
outstanding hereunder, together with interest thereon as hereinafter set forth.

         This Note is a note under which advances, repayments and new advances
may be made from time to time, provided that Bank shall not be obligated to make
any advance hereunder. Advances hereunder may be requested in Maker's discretion
by telephonic notice to Bank or by submission of a request for advance in form
annexed hereto as Exhibit "A". Any advance requested by telephonic notice (i)
shall be made only to Account No. 1076111614 with Bank in the name of Maker or
to such other account as Maker shall subsequently designate by written notice to
Bank, and (ii) shall be confirmed by Maker that same day by submission to Bank
by first class mail of the written request for advance aforementioned. Maker
acknowledges that if Bank makes an advance based on a telephonic request, it
shall be for Maker's convenience and all risks involved in the use of such
procedure shall be borne by Maker, and Maker expressly agrees to indemnify and
hold Bank harmless therefor. Bank shall have no duty to confirm the authority of
anyone requesting an advance by telephone.

         Each advance outstanding under this Note from time to time shall bear
interest at a per annum rate equal to Bank's prime rate established by Bank from
time to time or such other rate accepted by Bank with respect thereto, and shall
be payable upon the repayment date therefor. The amount, rate and repayment date
of each advance shall be noted on Bank's records, which records will be prima
facie evidence thereof, absent manifest error. Failure to pay any advance on its
repayment date, without Bank's consent, shall constitute a default and such
advance shall thereafter bear interest at three percent (3%) above said prime
rate as it may vary from time to time until paid. Interest shall be computed on
a daily basis using a year of 360 days and assessed for the actual number of
days elapsed. Interest on each advance shall be payable monthly on the last day
of each month in the case of a prime based advance, and in all other cases on
the respective repayment date therefore which date shall not be later than the
maturity date of this Note.

         This Note replaces the Promissory Note dated April 29, 1994 by Maker
payable to Bank, which Promissory Note was a renewal of a certain Promissory
Note dated June 17, 1993 in the principal amount of $5,000,000 by Maker payable
to Bank.

         Whenever Bank deems itself insecure, or on default in payment of any
liability hereunder, or upon the occurrence of any Default as defined under that
Scotsman Group Inc. $90,000,000 Revolving Credit Agreement dated as of April 29,
1994, among Maker, The First National Bank of Chicago, as Agent, Bank, as
lender, and the various banks listed on the signature pages thereof, the
representations, warranties, covenants and default provisions of which are
hereby incorporated by reference into this Note,
<PAGE>   2
notwithstanding the earlier termination and expiration of said Revolving Credit
Agreement, as said representations, warranties, covenants and default provisions
may be amended from time to time in writing by and between the parties thereto,
or upon any default in payment of any other liability of Maker to Bank and
continuance thereof beyond any period of grace, if any, provided with respect
thereto, the Bank may declare this Note due forthwith. Nothing herein shall
limit any right granted Bank by other instrument or by law.

                     REAFFIRMATION OF GUARANTY AND CONSENT

The undersigned has previously executed a Guaranty Agreement dated July 1, 1993
(the "Guaranty") in favor of COMERICA BANK-ILLINOIS (the "Lender") whereby the
undersigned unconditionally guaranteed to Lender the payment and performance of
any and all indebtedness, obligations and liabilities heretofore, now, or
hereafter owed by Scotsman Group Inc., a Delaware corporation (the "Borrower")
to Lender, including, without limitation, the payment and performance of
Borrower's Promissory Note dated April 29, 1994 in the principal sum of
$5,000,000 payable to the order of Lender with interest as therein described,
with the entire unpaid principal balance and accrued interest due on June 30,
1995 (the "Revolving Note") evidencing a $5,000,000 guidance line of credit loan
(the "Revolving Loan") extended by Lender to Borrower, and all loans and
advances made by Lender to Borrower thereunder.

The undersigned have been advised that Borrower has asked Lender to increase the
Revolving Loan from $5,000,000 to $9,000,000 and extend the maturity date
thereof to June 30, 1996, which would require the Borrower to execute two new
Promissory Notes in the aggregate principal sum of $9,000,000 payable to the
order of Lender with interest as therein described and with a maturity date of
June 30, 1996 (the "New Notes").

The undersigned has reviewed the New Notes and fully understands the terms and
provisions.

To induce Lender to increase the Revolving Loan to $9,000,000 and extend the
maturity date thereof to June 30, 1996 as aforesaid, the undersigned represents
and warrants to the Lender with the intent that the Lender rely thereon, as
follows:

1.       The Guaranty is in full force and effect and is binding and enforceable
against the undersigned in accordance with its terms;

2.       The undersigned irrevocably consents and agrees to Borrower's
execution, delivery and performance of the New Notes;

3.       The liability of the undersigned to the Lender under the Guaranty shall
in no way be affected, modified, altered, or discharged in any fashion by the
Borrower's execution, delivery or performance of the New Notes;

4.       The undersigned hereby restates and reaffirms all terms and provisions
of the Guaranty as if set forth in full herein; and

5. The undersigned does not possess any claims, defenses, offsets, or
counterclaims against the enforcement of the Guaranty, and the undersigned is,
and shall remain, unconditionally liable under the Guaranty for all
indebtedness, obligations, and liabilities heretofore, now or hereafter owed by
Borrower
<PAGE>   8
to Lender in accordance with the terms of the Guaranty, including, without
limitation, the indebtedness evidenced by the New Notes, and all extensions,
renewals, modification, and refinancings thereof.
