Corporation. If any payment hereunder becomes due and payable on a day other
than a business day, the due date thereof shall be extended to the next
business day and, with respect to payments of principal, interest thereon

         3.     Right to Prepay. The Corporation shall have the right to
                ---------------
prepay all or any part of the Note; provided, however, that (i) the
Corporation must give written notice to the Holder of its intention to make
any such prepayment not less than five (5) and not more than ten (10)
business days in advance of such prepayment, which notice must include a
representation that the funds to effect the prepayment are legally available
for that purpose and that representation must be supported by evidence
reasonably satisfactory to the Holder that such funds will be provided to the
Corporation at the time specified in the notice for prepayment, and (ii)
during the period following that notice and prior to the actual prepayment,
the Holder shall be entitled to exercise the conversion privilege set forth

available by its terms, or Section 4(b) hereof.

         4.     Right to Convert.
                ----------------

                (a)      At any time before the close of business on the
         Maturity Date but after the earlier of (A) termination of the Fifth
         Amended and Restated Agreement and Plan of Merger (the "Merger
         Agreement"), dated as of September 27, 2001, among the Corporation,
         the Holder and AMCON Merger Sub, Inc. ("Merger Sub") or (B) the
         occurrence of an Event of Default, the Holder may convert the
         outstanding principal balance and unpaid accrued interest of this
         Note into fully paid and non-assessable shares of Series C
         Convertible Preferred Stock, par value $1.00 per share, of the
         Corporation (the "Preferred Stock"). The price at which shares of
         Preferred Stock shall be delivered upon conversion (herein called
         the "Preferred Conversion Price") shall be $1.00 per share of
         Preferred Stock.

                (b)      At any time before the close of business on the
         Maturity Date, the Holder may convert the outstanding principal
         balance and unpaid accrued interest of this Note into fully paid and
         non-assessable shares of common stock of the Corporation (the
         "Common Stock"). The price at which shares of Common Stock shall be
         delivered upon conversion shall be $0.40 per share; provided,
         however, that if the Corporation shall at any time increase or
         decrease the number of its outstanding shares of Common Stock or
         change in any way the rights and privileges of such shares by means
         of the payment of a stock dividend or any other distribution upon
         such shares payable in Common Stock, or through a stock split,
         subdivision, consolidation, combination, reclassification or
         recapitalization involving the Common Stock, then the price at which
         shares shall be delivered upon conversion shall be proportionately
         increased or decreased, as the case may be, to avoid dilution of the
         number and kind of shares to which the Noteholder is fairly entitled
         upon conversion of the Note.

                (c)      This Note may be converted in whole, but not in part,
         into Preferred Stock or Common Stock or a combination thereof
         (referred to collectively as the "Conversion Shares") based on the
         terms set forth in subsections (a) and (b) of this Section 4, as the
         case may be.

         5.     Mechanics of Conversion. If the Holder desires to exercise
                -----------------------
such right of conversion, such Holder shall give written notice to the
Corporation in the form attached to this Note as Exhibit A (the "Conversion
Notice") of that Holder's election to convert a stated whole dollar amount of
outstanding principal balance and unpaid accrued interest of the Note into
shares of Preferred Stock, and/or Common Stock, as the case may be, and
surrender to the Corporation, at its principal office or at such other office
or agency maintained by the Corporation for such purpose, this Note. The
Conversion Notice shall also contain a statement of the name or names (with
addresses) in which the certificate or certificates for Preferred Stock
and/or Common Stock, as the case may be, shall be issued. Notwithstanding the
foregoing, the Corporation shall not be required to issue any certificates to
any person other than the Holder thereof unless the Corporation has obtained
reasonable assurance that such transaction is exempt from the registration
requirements of, or is covered by an effective registration statement under,
the Securities Act of 1933, as amended (the "Act"), and all applicable state
securities laws, including, if necessary in the reasonable judgment of the
Corporation or its legal counsel, receipt of an opinion to such effect from
counsel reasonably satisfactory to the Corporation. In no event would such
opinion be required if the shares of Preferred Stock and/or Common Stock, as
the case may be, could, upon conversion, be resold pursuant to Rule 144 or
Rule 144A under the Act. As promptly as practicable, and in any event within
two business days, after the receipt of the Conversion Notice (the "Date of
Conversion") and the surrender of the certificate or certificates
representing the Conversion Shares, the Corporation shall issue and deliver,
or cause to be delivered, to the Holder or his nominee or nominees, a
certificate or certificates for the number of shares of Preferred Stock
and/or Common Stock, as the case may be, issuable upon the conversion of this
Note. Such conversion shall be deemed to have been effected as of the close
of business on the Date of Conversion and the replacement Note, and the
person or persons entitled to receive the shares of Preferred Stock and/or
Common Stock, as the case may be, issuable upon conversion shall be treated
for all purposes as the holder or holders of record of such shares of
Preferred Stock and/or Common Stock, as the case may be, as of the close of
business on such date.

         6.     Fractions of Share. The Corporation shall not be required to
                ------------------
issue fractions of a share or scrip representing fractional shares of
Preferred Stock and/or Common Stock, as the case may be, upon the exercise of
any conversion right hereunder. If any fraction of a share of Preferred Stock
and/or Common Stock, as the case may be, would, except for the provisions of
this Section 6, be issuable upon any conversion exercise, the Corporation
shall pay a cash adjustment in respect of such fraction, equal to the value
of such fraction based on the Conversion Price per share of Preferred Stock.

         7.     Security. The obligations herein are secured by the security
                --------
interest granted pursuant to that certain Fourth Amended and Restated 10%
Secured Convertible Note in the principal sum of $350,000.00 payable by the
Corporation to Holder due on December 31, 2001 (and as such note may be
further amended and/or restated).

         8.     Corporation Covenants. The Corporation represents, warrants,
                ---------------------
covenants and agrees that:

                (a)      Any shares of Preferred Stock and/or Common Stock,
         as the case may be, delivered upon conversion of this Note shall, at
         the time of delivery of the certificates for

                                      3

<PAGE>

         such shares of Preferred Stock or Common Stock, be validly issued
         and outstanding and fully-paid and non-assessable shares of
         Preferred Stock or Common Stock free from taxes, liens and charges
         with respect to their purchase. Without limiting the generality of
         the foregoing, the Corporation covenants and agrees to take any
         necessary actions to assure that the par value per share of the
         Preferred Stock is at all times equal to or less than the then
         current Conversion Price per share for the Preferred Stock issuable
         pursuant to this Note. The Corporation further covenants and agrees
         that it will pay when due and payable any and all federal and state
         original issue stock taxes, if any, which may be payable in respect
         of the issue of the shares of Preferred Stock or Common Stock upon
         the conversion of this Note or a part hereof. Except for an
         amendment required pursuant to the foregoing sentence, the
         Certificate of Designation, Preferences and Rights of the Preferred
         Stock shall not be amended without the prior written consent of the
         Holder.

                (b)      The Corporation shall at all times reserve and keep
         available a number of its authorized but unissued shares of
         Preferred Stock and Common Stock which will be sufficient to permit
         the full exercise of this Note. If at any time the number of
         authorized but unissued shares of Preferred Stock or Common Stock is
         not sufficient for this purpose, the Corporation shall take such
         corporate actions as may be necessary to increase its authorized but
         unissued shares of Preferred Stock and/or Common Stock, as the case
         may be, to a number of shares sufficient for such purpose.

                (c)      (i)     The Corporation is duly organized as a
         corporation under the laws of the State of Hawaii, it is authorized
         to transact business in all jurisdictions where the conduct of its
         business requires it to be qualified, and it is duly authorized to
         execute, deliver and perform under this Note without the necessity
         of obtaining any consents or approvals of, or the taking of any
         other action with respect to, any governmental agency or third
         party; and

                         (ii)    The financial statements submitted to Holder
         fairly present the financial condition of the Corporation as of the
         date of this Note knowing that Holder has relied thereon in granting
         the Loan, there have been no material adverse changes in the
         financial condition of the Corporation since the date of said
         financial statements, the Corporation has no material obligations,
         financial or otherwise, not disclosed to Holder, and at the present
         time there are no material, unrealized or anticipated losses from
         any present commitment of the Corporation.

                (d)      The Corporation shall give written notice to the
         Holder at least 10 days prior to establishing a record date to
         determine the stockholders of record entitled to vote on the merger
         contemplated by the Merger Agreement in order to permit the Holder
         to exercise the right to convert this Note and vote upon such merger
         and to receive merger consideration pursuant to such merger.

         9.     Rights of Holder. The Holder of this Note shall not be
                ----------------
