                                 PROMISSORY NOTE

$1,360,000.00                                                   Edina, Minnesota
                                                                     May 3, 2004

      FOR VALUE RECEIVED, the undersigned, WSI Industries, Inc., a Minnesota
corporation ("Borrower"), promises to pay to the order of Excel Bank Minnesota
("Lender"), a banking institution organized and existing under the laws of
Minnesota, at 50 South Sixth Street, Suite 1000, Minneapolis MN 55402 or at any
other place designated from time to time by the holder hereof, in lawful money
of the United States of America, pursuant to the terms hereof, the principal sum
of One Million Three Hundred and Sixty Thousand and 00/100 ($1,360,000.00)
Dollars, together with interest (computed on the basis of the actual number of
days that have elapsed in a 360-day year) on the principal amount of this Note
outstanding from time to time at the initial rate of interest of five and
thirty-seven one hundredths (5.37%) percent per annum.

      Such rate of interest shall be adjusted on May 3, 2009 ("Change Date"), at
which time the rate of interest shall be adjusted to two and one half (2.50%)
percent above the monthly yield on United States Treasury Securities adjusted to
a constant maturity of five (5) years as published in the most recent
publication of the Federal Reserve Board's Statistical Release H.15(519)
("Index"). If such Index is no longer published or is not otherwise available,
the holder hereof may designate a reasonable alternative, which shall thereafter
serve as the Index hereunder. On the Change Date, the Lender shall calculate the
new interest rate by adding two and one half (2.50) percentage points to the
Index rate. Thereafter, such new interest rate shall be the interest rate under
the Note.

      Said principal and interest shall be paid in monthly installments of not
less than $8,307.00 commencing on June 1, 2004 and continuing monthly thereafter
on the first (1st) day of each and every month until the Change Date, at which
time the monthly payments hereunder shall be adjusted such that said payments
are sufficient to amortize the entire outstanding balance originally due
hereunder, based on an assumed twenty-five (25) year amortization beginning on
the date hereof and based on the new rate of interest. Said monthly payments in
such new amount shall continue each and every month until May 1, 2014, at which
time the entire remaining balance due and owing hereunder, including all
principal and accrued but unpaid interest, shall be due and payable in full.

      Payments hereunder shall be applied first to accrued but unpaid interest,
and then to principal.

      This Note is secured in part by a Mortgage and Security Agreement and
Fixture Financing Statement upon certain real property located in Wright County,
Minnesota, and is made in conjunction with a Loan Agreement and related
documents of even date herewith.

      If any installment hereof is not paid within five (5) days of the date
when due, or if the undersigned shall fail to perform or observe any obligation
binding upon the undersigned under any mortgage or security instrument securing
this Note and is not cured within applicable grace periods

<PAGE>

or under any other agreement between the undersigned and the holder hereof and
is not cured within applicable grace periods, or if any default or event of
default shall occur under any such agreement, then (in any such event) the
holder hereof may, at its option, declare the entire principal balance then
remaining unpaid on this Note to be immediately due and payable, and the same
shall thereupon be immediately due and payable, together with all interest
accrued hereon, without notice or demand.

      Notwithstanding anything to the contrary herein, during the continuance of
any event or condition of default hereunder or under any contract, agreement,
obligation or liability of the undersigned in favor of the Lender, Lender, at
its option, may if permitted under applicable law, and after any applicable
notice or cure period, increase the variable rate of interest on this Note to
two (2.00) percentage points over and above the otherwise applicable rate under
this Note. Under no circumstances shall the rate of interest hereunder exceed
the maximum rate permitted by law.

      If any installment hereunder or other payment due to the Lender is paid
more than ten (10) days after its due date, the undersigned shall owe to the
Lender the sum of five (5.00%) percent of the scheduled installment or payment
or Five and 00/100 ($5.00) Dollars, whichever is greater.

      The Borrower may prepay the Note provided that any additional principal
payments beyond the regularly scheduled payment amounts shall be subject to a
prepayment premium of one (1.00%) percent of principal prepaid. Notwithstanding
the foregoing to the contrary, Borrower may prepay up to an additional ten
(10.00%) percent of the outstanding principal balance of the Note in each
calendar year, without penalty. Notwithstanding the foregoing, the prepayment
premium shall be waived by the holder of this Note, in the event that prepayment
of this Note in full is tendered to the holder within the sixty (60) days
immediately preceding the Change Date.

      To the extent permitted by law, the undersigned agrees to pay all costs of
collection, including reasonable attorneys' fees and legal expenses, incurred by
the holder hereof in the event this Note is not duly paid.

      Presentment or other demand for payment, notice of dishonor and protest
are hereby expressly waived.

                                 LOAN AGREEMENT

      This Loan Agreement ("Agreement") is made this 3rd day of May, 2004, by
and among WSI Industries, Inc., a Minnesota corporation, having the address
described in section VII.F hereof ("Borrower"), Excel Bank Minnesota, having a
principal business address of 50 South Sixth Street, Suite 1000, Minneapolis MN

      WITNESSETH:

      WHEREAS, Borrower seeks to obtain a loan from Lender in the amount of One
Million Three Hundred and Sixty Thousand and 00/100 ($1,360,000.00) Dollars to
acquire title to the real property located in Wright County, Minnesota which
property is legally described on the attached Exhibit A ("Mortgaged Premises");
and

      WHEREAS, the Lender desires to loan One Million Three Hundred and Sixty
Thousand and 00/100 ($1,360,000.00) Dollars to Borrower pursuant to and subject
to the terms and conditions of this Agreement.

      NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by the parties, the parties agree
as follows:

I.    THE LOAN.

      The Lender shall loan to Borrower the sum of One Million Three Hundred and
Sixty Thousand and 00/100 ($1,360,000.00) Dollars ("Loan") pursuant to the terms
and conditions of a promissory note ("Promissory Note") in form and substance
acceptable to Lender. The Loan shall bear interest and all payments shall be
made as described in the Promissory Note.

<PAGE>

      A. The parties acknowledge and agree that the sole purpose of the Loan is
      to enable Borrower to acquire title to the Mortgaged Premises. Borrower
      shall be in default under this Agreement if any of the proceeds from the
      Promissory Note are used for any purpose other than as described above.

      B. Borrower shall, on or before the execution hereof, provide Lender a
      Phase I Environmental Investigation Report regarding the Mortgaged
      Premises. The Loan shall be conditioned upon Lender, in Lender's sole
      discretion, being satisfied with the results of the Phase I Environmental
      Investigation Report.

      C. The Lender may maintain from time to time, at its discretion, liability
      records as to any and all loans made or repaid and interest accrued or
      repaid under this Agreement. All entries made on any such record shall be
      presumed correct until Borrower establishes the contrary. On demand by the
      Lender, Borrower will admit and certify in writing the exact principal
      balance that Borrower then asserts to be outstanding to the Lender for the
      Loan. Any billing statement or accounting rendered by the Lender shall be
      conclusive and fully binding on Borrower unless specific written notice of
      exception is given to the Lender at its address described above by
      Borrower within thirty (30) days after its receipt by Borrower.

      D. Borrower shall, on or before the execution hereof, reimburse Lender for
      all of Lender's reasonable attorneys' fees and all related costs incurred
      by the Lender in drafting this Agreement, the related documents,
      negotiating its terms with the parties hereto and establishing Lender's
      collateral position, including title insurance costs. Borrower agrees that
      Lender may at any time or from time to time, without further request by or
      notice to Borrower, make a loan to Borrower in the sum of such attorneys'
      fees and costs and add such indebtedness to other indebtedness of Borrower
      under the Promissory Note or the Lender may apply proceeds of the
      Promissory Note directly to pay such attorneys' fees and costs.

      E. Prior to the execution hereof, Borrower shall cause to be delivered to
      the Lender, at Borrower's expense an appraisal certified to the Lender for
      the Mortgaged Premises by an M.A.I. appraiser acceptable to the Lender,
      engaged by the Lender. The appraisal shall be satisfactory to Lender in
      all respects. The initial appraisal shall provide for a current, as is
      market value of the Mortgaged Premises not to exceed seventy-two (72.00%)
      percent loan to value based on the total principal amount of the Loan on
      the date hereof.

      F. Borrower acknowledges and agrees that Borrower shall pay an origination
      fee to the Lender of Six Thousand Eight Hundred ($6,800.00) Dollars, which
      origination fee shall be paid in certified funds or cash on or before the
      closing of the Loan.

      adverse change in the financial condition of Borrower. So long as any sums
      remain due and payable pursuant to the Promissory Note, Borrower shall

      audit to the Loan) or otherwise declare an Event of Default hereunder.
      Lender also shall have the right to examine at their place of safekeeping
      at reasonable times all books, accounts and records relating to the
      business operations of the Borrower and the operation of the Mortgaged

      protection or enforcement of the interest and collateral security of the
      Lender in any litigation or bankruptcy or insolvency proceeding or the
      prosecution or defense of any action or proceeding relating in any way to
      the transactions contemplated by this Agreement.

      C. Borrower shall furnish to the Lender as soon as possible and in any
      event within ten (10) days after the Borrower has obtained knowledge of
      the occurrence of an event which would constitute an Event of Default
      hereunder or a violation of any of the covenants or obligations of the
      Borrower under this Agreement or which would cause any of the
      representations or warranties hereunder to be false or misleading in any
      material respect, or an event which with the giving of notice of lapse of
      time or both would constitute an Event of Default, which is continuing on
      the date of such statement, in which case the Borrower, as applicable
      shall deliver a signed statement setting forth details of such violation
      or event and the action which has been taken, are taking, or propose to
      take to correct the same.

      D. Borrower shall pay and discharge all taxes, assessments and
      governmental charges or levies imposed upon either Borrower or upon
      Borrower's income, or profits, or upon Borrower's assets or properties,
      prior to the date on which penalties attach thereto, and all lawful claims
      which, if unpaid, might become a lien or charge upon the property or
      assets of either the Borrower; provided, however, that the Borrower shall
      not be required to pay any such tax, assessment, charge, levy or claim,
      the payment of which is being contested in good faith and by proper
      proceedings and for which they shall have set aside adequate reserve
      therefor.

      E. The performance or observance of any promise or condition set forth in
      this Agreement may be waived in writing by the Lender, but not otherwise.
      No delay in the exercise of any power, right, or remedy of the Lender
      shall operate as a waiver thereof, nor shall any single or partial
      exercise thereof or the exercise of any other power, right, or remedy.

      F. The Lender and its participants, if any, are not general partners or
      joint venturers with Borrower and the Lender shall not have any liability
      or responsibility for any obligation, act, or omission of any of its
      participants.

      of the Exhibits hereto shall be provided at the addresses listed below:

      H. Borrower agrees that the Lender may at any time or from time to time,
      at its sole discretion and without demand and without notice to anyone,
      set off any liability owed to Borrower by the Lender, whether or not due,
      against any indebtedness owed to the Lender by Borrower (for the Loan or
      for any other transaction or event, including both loans retained by the
      Lender and loans in which the Lender has granted any person or entity a
      participation), whether or not due. In addition, each entity or other
      person holding a participating interest in any loans made to Borrower by
      the Lender shall have the right to appropriate or set off any deposit or
      other liability then owed by such entity or person to Borrower whether or
      not due, and apply the same to the payment of said participating interest,
      as fully as if such bank or person had lent directly to Borrower the
      amount of such participating interest.

      I. Notwithstanding anything to the contrary in any other document executed
      in conjunction herewith, any written notice required by this Agreement or
      any other document executed in conjunction herewith, shall be deemed
      received upon mailing, regular or certified mail, to the parties at the

      L. This Agreement shall be binding upon Borrower and Borrower's successors
      and assigns, and shall inure to the benefit of the Lender and its
      participants, successors, and assigns. All rights and powers specifically
      conferred upon the Lender may be transferred or delegated by the Lender to
      any of its participants, successors, or assigns. If any provision or
      application of this Agreement is held unlawful or unenforceable in any
      respect, such illegality or unenforceability shall not affect other
      provisions or applications which can be given effect, and this Agreement
      shall be construed as if the unlawful or unenforceable provision or
      application had never been contained herein or prescribed hereby. All
      representations and warranties contained in this Agreement or in any other
      agreement between Borrower and the Lender shall survive the execution,

      of any indebtedness to the Lender. Borrower waive notice of the acceptance
      of this Agreement by the Lender.

      deemed to be an original and all of which, when taken together, shall
      constitute one instrument.

      N. No failure or delay on the part of the Lender in exercising any right,
      power or remedy hereunder or under the Mortgage, or any other instrument
      binding on the Borrower shall operate as a waiver thereof; nor shall any
      single or partial exercise of any such right, power or remedy preclude any
      other or further exercise thereof or the exercise of any other right power
      or remedy hereunder or under any other agreement or instrument

                                        9

      O. No amendment, modification, termination or waiver of any provision of
      this Agreement, the Mortgage or the Promissory Note or consent by the
      Borrower to any departure therefrom shall be effective unless the same
      shall be in writing and signed by the Lender and then such waiver or
      consent shall be effective only in the specific instance and for the
      specific purpose for which given. No notice to or demand on the Borrower
      in any case shall entitle the Borrower to any other or further notice or
      demand in similar or other circumstances.
