                  with monthly installments that equally blend principal and
                  interest in the amount of $1,085.43 each. The first of such
                  installments shall be due on the 10th day of November, 2002

                  subject to a late fee in an amount equaling ten percent of the
                  scheduled payment due that month or $50 whichever is greater.

           5.     If the Borrower does not include the late charge with their
                  next payment, the next payment will be applied to the late
                  charge first, interest next, and principal last.

                  added to the late charges at the same rate as on the balance
                  of the loan.

           7.     Board of Directors of the Areawide Business Council may
                  forgive the late charges and interest on late charges if it is
                  deemed necessary or beneficial to ABC.

                           employment practices will result in unequal treatment

         3.       It will insure that the facilities under its ownership, lease,
                  or supervision which shall be utilized in the accomplishment
                  of the project are not listed on the Environment Protection

                  1976. Section 102(a) requires, on and after March 2, 1975, the
                  purchase of flood insurance in communities where such
                  insurance is available as a condition for the receipt of any
                  Federal financial assistance for construction or acquisition
                  purposes for use in any area that has been identified by the
                  Federal Emergency Management Agency (FEMA) as an area having
                  special flood hazards. The phrase "Federal financial

                  with Section 106 of the National Historic Preservation Act of
                  1966, as amended (16 U.S.C. 470), Executive Order 11593, and

                  Preservation Officer on the conduct of investigations, as
                  necessary, to identify properties listed in or eligible for
                  inclusion in the National Register of Historic Places that are
                  subject to adverse effects (See 36 CFR Part 800.8) by the

         6.       It will give Lender or the Economic Development Administration
                  through any authorized representative the access to the right

         7.       It will comply with Section 2 of the Public Works and Economic
                  Development Act of 1965, as amended, which states that under
                  the provisions of this Act new employment opportunities should
                  be created by developing and expanding new and existing
                  facilities and resources rather than by merely transferring
                  jobs from one labor area to another.

         8.       It will assure that any building or facility financed in whole
                  or in part by any funds provided under the RLF will be
                  designed, constructed or altered so as to assure ready access
                  to and use of such building or facility by the physically
                  handicapped. This provision applies only to firms which deal
                  directly with the general public in the normal and usual
                  course of their business, and to facilities in which business
                  is customarily transacted by and with members of the general
                  public.

         9.       It will comply with the Davis Bacon Act, as amended (40 U.S.C.

         11.      It, with all other applicable federal, state, county or
                  municipal statutes, ordinances, rules or regulations as they
                  may apply to M-Tron Industries, Inc. in the operations of its
                  business in Yankton County, South Dakota.

$100,000                                                         October 9, 2002

         For value received, the undersigned, M-TRON INDUSTRIES, INC. (hereafter
sometimes referred to as "Debtor") promises to pay to the order of Areawide
Business Council, Inc. (hereafter referred to as "Holder") at its office in the
City of Yankton, State of South Dakota or at such other place as may be
designated from time to time by the Holder, the principal sum of One Hundred
Thousand Dollars and no Cents ($100,000.00) together with interest on the unpaid
balance of the principal remaining from time to time unpaid at the rate of Five
and one half percent (5.5%) per annum; interest shall commence and be computed
from October 9, 2002, at said rate; said loan and the payments thereon shall be
paid as follows:

         The One Hundred Thousand Dollars and no Cents ($100,000.00) will be
         amortized over a 120 month period with installments that equally blend
         principal and interest in the amount of $1,085.43 each, with the first
         of such installments due on the 10th day of November, 2002, and with a
         like installment due on the 10th day of each month thereafter until
         November 10, 2007 when the entire remaining principal balance, together
         with accumulated interest, shall become due and paid in full. All
         payments made upon this Promissory Note shall be applied first to the
         payment of accrued interest and then to the reduction of principal.
         This payment schedule is based upon the amortization schedule attached
         hereto as Attachment A which amortization schedule assumes that all
         payments due on this Promissory Note are paid in full when due.
         Variation of actual payment date from the required and anticipated
         payment date shall affect and cause variance from the specific
         calculations shown upon the said amortization schedule.

         This Promissory Note is made and given in conjunction with the Loan
Agreement between the parties and is secured by the Mortgage bearing even date
herewith. Default of any term or condition of any of said documents or
agreements shall be deemed a default of this Promissory Note entitling the
Holder to all of the rights and remedies of the Secured Party Creditor as
provided in the said agreements, documents and guaranties and as provided by
law.

         Any sum payable hereunder and not paid when due, including the entire
unpaid balance upon acceleration, shall bear interest at the default rate of 12%
per annum until paid.

         This Promissory Note or any portion thereof may be prepaid on any
payment date without penalty; provided that any prepayment shall not relieve the
Borrower of its obligation to make the monthly installments due on the first day
of each month until this Promissory Note is paid in full.

<PAGE>

         The makers, endorsers, and guarantors hereof waive presentment, demand
of payment, notice of non-payment, protest and notice of protest, and agree that
any extensions of the time made hereon or renewals hereof shall not affect their
liability, regardless whether they have notice of such extensions or renewals.

         The Indebtedness evidenced hereby, including all principal, interest
and expense charges (hereafter called the "Indebtedness"), shall immediately
become due and payable, without notice or demand, upon the appointment of a
receiver or liquidator, whether voluntary or involuntary, unless any involuntary
proceeding is dismissed within thirty (30) days of filing, for the undersigned
Debtor or for any of its property, or upon the filing of a petition by or
against the undersigned Debtor under the provisions of any State insolvency law
or under the provisions of the Bankruptcy Reform Act or 1978, as amended, or
upon the making by the undersigned Debtor of an assignment for the benefit of
its creditors.

         The Holder hereof is authorized to declare all or any part of the
Indebtedness immediately due and payable upon the happening of any of the
following events: [1] Failure to pay any part of the Indebtedness within ten
(10) days when due; [2] non-performance by the undersigned Debtor of any
agreement with, or any condition imposed by Holder with respect to the
Indebtedness in any note, security agreement, or loan agreement with Area wide
Business Council, Inc. not cured within thirty (30) days of notice to Debtor;
[3] Holder's discovery of the failure of Debtor or its parent company to
disclose any fact deemed by Holder to be material to the making of this Loan, or
any misrepresentation by, on behalf of, or for the benefit of the undersigned
Debtor; [4] the reorganization (other than a reorganization pursuant to any of
the provisions of the Bankruptcy Reform Act of 1978, as amended) or merger or
consolidation of the undersigned Debtor (or the making of any agreement
therefor), other than within Debtor's own organization without the prior written
consent of Holder; [5] the undersigned Debtor's failure duly to account to
Holder's satisfaction within ten (10) days of notice, at such time or times as
Holder may require, for any of the Collateral, or proceeds thereof coming into
the control of the undersigned Debtor, [6] if any final judgment for the payment
of money that is not fully covered by liability insurance shall be rendered
against the Borrower, which would have a material adverse effect on the
financial status of borrower, and within sixty (60) days shall not be
discharged, or an appeal therefrom taken and execution thereon effectively
stayed pending such appeal, and if such judgment be affirmed on such appeal and
the same shall not be discharged within thirty (30) days; or [7] if Debtor or
its parent company should violate any other covenant contained in the loan
documents, including the Loan Agreement and the Security Agreement and other
documents related thereto. Holder's failure to exercise its rights under this
paragraph shall not constitute a waiver thereof.

         None of the rights, remedies, privileges or powers of Holder expressly
provided for herein shall be exclusive, but each of them shall be cumulative
with and in addition to every other right, remedy, privilege and power now or
hereafter existing in favor of Holder, whether at law or equity, by statute or
otherwise.

         The Borrower agrees if, at any time, the Borrower defaults on any
provision of this Loan Agreement, to pay the Lender in addition to any other
amounts that may be due from

                                       2

<PAGE>

the Borrower, an amount equal to the costs and expenses of collection,
enforcement, or correction or waiver of the default incurred by the Lender's
rights under the Note, the prevailing party shall pay reasonable Attorney's fees
including Attorney's fees on appeal,

         The rights of Holder and its assigns hereunder and the security rights
granted in the Security Agreement granted simultaneously herewith shall not be
impaired by Holder's sale, hypothecation or re-hypothecation of the Promissory
Note or any item of Collateral, or by any indulgence, including but not limited
to (a) any renewal, extension, or modification which Holder may grant with
respect to the Indebtedness or any part thereof, or (b) any surrender,
compromise, release, renewal, extension, exchange or substitution which Holder
may grant in respect of the Collateral, or (c) any indulgence granted in respect
of any endorser, guarantor or surety. The purchaser, assignee, transferee or
pledgee of this Note, the Collateral and Guaranty and any other document (or any
of them) sold, assigned, transferred, pledged or repledged shall forthwith
become vested with and entitled to exercise all the powers and rights given by
this Promissory Note and all applications of the undersigned as if said
purchaser, assignee, transferee, or pledgee were originally named as payee
therein.
