ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     On February 15, 1999, WSI Industries, Inc. (the "Registrant") purchased 
all of the issued and outstanding stock of Taurus Numeric Tool, Inc., a 
Minnesota corporation based in Osseo, Minnesota ("Taurus"), from Rodney 
Winter ("Winter"). Taurus and Winter have no affiliation to the Registrant or 
any of its affiliates.  Taurus is in the business of custom precision 
contract machining. Taurus will continue to operate its assets in the same 
business.  Pursuant to a Stock Purchase Agreement dated February 15, 1999 
between the Registrant and Winter (the "Stock Purchase Agreement"), 
$1,175,807 was paid by the Registrant to Winter in the form of a Subordinated 
Promissory Note subordinate to the interests of U.S. Bank National 
Association ("U.S. Bank") and $5,000,000 was paid in cash derived from cash 
on hand and from borrowings from U.S. Bank.  An additional as yet 
undetermined amount (not to exceed $1,000,000) will be payable by the 
Registrant to Winter in the form of a Contingent Subordinated Promissory 
Note, such amount to be based upon the operating income of Taurus during the 
twelve-month period following the closing date of the transaction.  The 
purchase price was determined through arms-length negotiations.  Upon the 
closing of the Stock Purchase Agreement, Taurus entered into a three-year 
lease with Winter and Reba Winter for the facility used in its business.  
Taurus and Winter also entered into a Non-Compete Agreement under which 
Winter will be paid $25,000 per quarter for five years.  The Registrant has 
guaranteed Taurus' obligations under the Lease and Non-Compete Agreement.

Corporation (the "Amended Agreement").  Pursuant to the Amended Agreement, 
U.S. Bank extended to the Registrant a term loan in the principal amount of 
$3,200,000 and a revolving credit facility in the maximum amount of 
$3,000,000.

                               STOCK PURCHASE AGREEMENT

     THIS STOCK PURCHASE AGREEMENT ("Agreement") dated February 15, 1999, is 
by and between WSI Industries, Inc., a Minnesota corporation (the "Buyer") 
and Rodney Winter (the "Seller").

                                       RECITAL

     Seller owns and desires to sell, and Buyer desires to purchase, 100% of 
the capital stock of Taurus Numeric Tool, Inc., a Minnesota corporation (the 
"Corporation"), upon the terms and subject to the conditions set forth in 
this Agreement.  

     It is agreed:

                                      ARTICLE I
                              PURCHASE AND SALE OF STOCK

     1.1. SALE OF COMMON STOCK.  Seller hereby agrees to sell, convey, 
transfer, assign and deliver to Buyer on the Closing Date (as defined in 
Section 1.7), 10,000 shares (the "Shares") of duly and validly issued, fully 
paid and non-assessable, common stock of the Corporation.

     1.2. PURCHASE PRICE.  Subject to the terms and conditions of this 
Agreement and in reliance upon the representations, warranties and covenants 
of Seller herein contained and in full consideration of such sale of the 
Shares to Buyer, Buyer agrees to pay to Seller a purchase price (the 
"Purchase Price") consisting of Six Million and no/100s Dollars ($6,000,000) 
subject to adjustment as provided in Sections 1.3 and 1.6 of this Agreement 
(the "Closing Payment") and (ii) the Additional Amount as described in 
Section 1.5.  The Closing Payment shall be paid as detailed in Section 1.4 of 
this Agreement.

     1.3. CLOSING DATE ADJUSTMENT.  Seller shall prepare and deliver to 
Buyer, not later than three (3) days before the Closing Date, the December 
31, 1998 balance sheet of the Corporation prepared from the books and records 
of the Corporation in accordance with generally accepted accounting 
principles consistently applied, but with the inventory valued as provided in 
Section 1.6 (the "Latest Balance Sheet").  If the sum of the book value of 
the Corporation as set forth on the Latest Balance Sheet, less $191,990, is 
different from the book value of the Corporation as set forth on the October 
31, 1998 Balance Sheet (excluding the book value of life insurance and 
vehicles) ($3,928,218) previously delivered to Buyer (the "October Balance 
Sheet"), the amount of the Note (as defined in Section 1.4) to be delivered 
at Closing shall be reduced or increased, as the case may be, on a dollar for 
dollar basis.

     1.4. CLOSING PAYMENT.  The Closing Payment shall be paid as follows:

          (a)  $5,000,000 in cash at Closing by wire transfer of funds; and


<PAGE>


          (b)  Subordinated Promissory Note (the "Note") delivered at Closing in
               the form attached hereto as Exhibit A in an amount equal to
               $1,000,000 as adjusted pursuant to Sections 1.3 and 1.6 of this
               Agreement.  The Note shall be secured as provided in the form of
               Security Agreement attached hereto as Exhibit B.

     1.5. ADDITIONAL AMOUNT.  Seller shall receive Two Dollars ($2.00) for every
One Dollar ($1.00) of Operating Income (as defined below) above One Million Four
Hundred Seventy-Five Thousand ($1,475,000) generated by the Corporation during
the twelve-month period following the Closing Date, up to a maximum of One
Million Dollars ($1,000,000)(the "Additional Amount").  For purposes of this
Agreement, Operating Income shall be defined as earnings (including earnings
from the sale of inventory described in Section 6.13) before interest, taxes and
acquisition costs, each as determined by the Corporation in accordance with
generally accepted accounting principles.  The Additional Amount will be
evidenced by a contingent subordinated promissory note (the "Contingent Note")
in the form of Exhibit C hereto delivered at Closing.  The Contingent Note shall
be secured as provided in the form of Security Agreement attached hereto as
Exhibit B.  In the event that, prior to the end of the twelve-month period
following the date of this Agreement, Buyer sells, exchanges, or otherwise
disposes of substantially all of the assets of the Corporation or more than 50%
of the outstanding capital stock of the Corporation to a third party, other than
Buyer or any subsidiary of Buyer (a "Change of Control"), then the Additional
Amount shall be determined by multiplying the average monthly Operating Income
for each month following the Closing Date, but prior to the Change of Control,
by twelve (12).

     1.6. POST-CLOSING ADJUSTMENT.

          (a)  Within 45 days after the Closing Date (as defined in Section
     1.7), the Buyer shall deliver to the Seller a balance sheet of the
     Corporation as of the opening of business on February 15, 1999 (the
     "Closing Date Balance Sheet") prepared by the Buyer.  The fees and expenses
     of the audit shall be paid by Buyer.  Such balance sheet shall be prepared
     in accordance with generally accepted accounting principles consistently
     applied, with the inventory value determined in a manner consistent with
     the Latest Balance Sheet and as provided in this Section 1.6.  There shall
     be accrued on the Closing Date Balance Sheet an expense related to certain
     equipment repairs with respect to the B-axis on the Mazak #1 and #2
     machines.  Such expense shall be determined by quote from Mazak.   The
     inventory reflected on the Closing Date Balance Sheet shall be determined
     by a physical inventory taken as of the start of business on the Closing
     Date and observed by the representatives of the Buyer and Seller.  The
     inventory will be valued at the lower of cost or market and shall consist
     of material, hardware and subcontract costs at their historical invoiced
     value; plus labor costs applied at a total hourly rate of $34.38 for
     work-in-progress and finished goods.  The only inventory set forth on the
     Closing Date Balance Sheet shall be raw materials, work-in-progress and
     finished goods inventory for which there are current orders from customers
     or forecasted orders from Rockwell Air


                                       2
<PAGE>

     Transport, or included on Rockwell's annual purchase agreement.  All other
     inventory shall be excluded and "Obsolete and Slow Moving Inventory."
     Obsolete and Slow Moving Inventory shall be subject to the terms of Section
     6.13.

          (b)  If the Seller has any objections to the Closing Date Balance
     Sheet, he shall deliver to the Buyer a statement describing such objections
     within 15 days after Seller's receipt of the Closing Date Balance Sheet. 
     If no objections are received within such 15 day period, the Closing Date
     Balance Sheet shall be deemed accepted by Seller.  Buyer and Seller shall
     use reasonable efforts to resolve any objections received during such 15
     day period.  In the event Buyer and Seller are unable to resolve such
     objections within a 15-day period following receipt by Buyer of Seller's
     objections, the Buyer and Seller shall, within ten days after such 15-day
     period, select a mutually acceptable nationally recognized accounting firm
     to resolve any remaining objections.  The determination of such accounting
     firm shall be made within 30 days of the selection of such accounting firm
     and shall be conclusive and binding upon the parties hereto.  The fees and
     expenses of such accounting firm shall be shared equally by Buyer and
     Seller.

          (c)  If the aggregate book value of the Corporation, as reflected on
     the Closing Date Balance Sheet, as finally determined, is greater than the
     aggregate book value of the Corporation as reflected on the Latest Balance
     Sheet, less $191,990, the Purchase Price shall be adjusted upward by such
     amount and a corresponding adjustment to the Note shall be made as of the
     Closing.  In the event the aggregate book value of the Corporation, as
     reflected on the Closing Date Balance Sheet, as finally determined, is less
     than the aggregate book value of the Corporation as reflected on the Latest
     Balance Sheet, less $191,990, the Purchase Price shall be adjusted
     downward by such amount and a corresponding adjustment to the Note shall be
     made as of the Closing.  The finalization of the Closing Date Balance Sheet
     shall not affect any rights or remedies of Buyer under this Agreement.  In
     the event a downward adjustment is in excess of the principal amount of the
     Note, such excess shall be paid by Seller to Buyer within five (5) days of
     final determination of such adjustment.

     1.7. CLOSING.  The closing of the transactions contemplated by this
Agreement (the "Closing") is taking place simultaneously with the execution of
this Agreement at the offices of Lindquist & Vennum PLLP, 4200 IDS Center, 80
South 8th Street, Minneapolis, Minnesota at 9:00 a.m. on February 15, 1999.  The
date and time of the Closing are herein referred to as the "Closing Date."  The
Closing shall be effective as of 12:01 a.m. on February 15, 1999.

     (Environmental), Section 2.11 (Taxes), Section 2.23 (Employee Benefits),
     Section 6.2 (Expenses) or Section 6.14 (Inventory) shall not be subject to
     the limitation contained in this Section 5.3(a). Notwithstanding the
     provisions of Section 5.1, Seller shall have no liability under Section 5.1
     with respect to any costs or expenses of any remediation unless ordered or
     demanded by a court, governmental body or agency, or other third party, or
     such remediation is required to be undertaken by applicable Environmental
     Law or is necessary in order for the Corporation to be in compliance with
     applicable Environmental Laws or would be voluntarily undertaken under
     customary business practices in the industry.

          (b)  Notwithstanding the provisions of Section 5.1, the aggregate
     Damages for which Buyer or the Corporation is entitled to indemnification
     pursuant to Section 5.1(a) shall not exceed an amount equal to the Closing
     Payment; provided Damages resulting from the breach of the representations
     and warranties in Section 2.3 (Title) shall not be subject to the foregoing
     limitation, but shall be limited to an amount equal to the Closing Payment
     and all other payments to be made by Buyer or Corporation to Seller under
     the other agreements referenced herein.

          (c)  Any proceeds from insurance paid to or on account of the Buyer as
     a direct result of any fact, event or circumstance requiring indemnity
     pursuant to Section 5.1 shall constitute a credit which shall be offset
     against the total Damage (before the application of Section 5.3(a)).

          (d)  Any damage calculated for purposes of Section 5.1 shall be
     calculated taking into account any offsetting federal, state, local or
     foreign tax benefits which may accrue because of such Damage to Buyer.

          (e)  On September 15, 2000, the parties shall be released from the
     agreements of indemnification contained in Sections 5.1 and 5.2 in respect
     of any claims which have not been made, in writing, prior to such date;
     provided, however, that (i) the Seller shall not be released from the
     agreements of indemnification arising under Section 5.1(a) with respect to
     breaches of representations and warranties contained in Section 2.3 (Title)
     or Section 2.11 (Taxes), or breaches of covenants in this Agreement, all of
     which shall continue until the applicable statute of limitations has
     expired; (ii) Seller shall not be released from the agreements of
     indemnification arising under Sections 5.1(b) or 5.1(d), all of which shall
     continue until the applicable statute of limitations has expired, at which
     time Seller shall be released from such agreements of indemnification; and
     (iii) the Seller shall not be released from the agreement of
     indemnification arising under Section 5.1(a) with respect to breaches of
     representations and warranties contained in Section 2.29 (Environmental) or
     under Section 5.1(c), each of which shall continue until February 15, 2004,
     at which time Seller shall be released from such agreements of
     indemnification.  Notwithstanding the foregoing, all agreements of
     indemnification under Sections 5.1 and 5.2 shall remain effective in
     respect of claims made in writing by giving notice as


                                      17
<PAGE>

     provided in this Agreement prior to such respective dates until such claims
     are finally determined and satisfied in full.

     5.4. GENERAL RELEASE.  On the Closing Date, Seller releases the Corporation
and its directors, officers, agents and employees and discharges them from any
and all obligations and claims which have arisen or might arise out of facts or
actions existing or taken on or prior to the Closing Date, except obligations or
claims which may be made under this Agreement, but including specifically the
Corporation's obligations under any oral or written lease for the Leased Real
Property.  In the event that Buyer is entitled to any claim for indemnification
under this Agreement against the Seller, the Seller agrees that he shall not
have the right to seek indemnity or contribution with respect to any such claim
from, or have any similar right with respect to, the Corporation, Buyer or their
affiliates whether by contract, agreement, bylaw, corporate law statute, common
law or otherwise.

     Plan shall assume all liabilities and obligations for benefits to the
     Transferred Plan Participants and their beneficiaries arising under the
     Profit Sharing Plan.

           (b)  NO THIRD PARTY BENEFITS. Nothing herein expressed or implied is
     intended or shall be construed to confer upon or give to any person, firm

     permitted successors and assigns, any rights or remedies under or by reason
     of this Agreement.

shall be received for the benefit of Seller and shall be assigned to him.  

     6.17. ENVIRONMENTAL MATTERS.  Buyer and Seller have received a copy of
a Phase I Environmental Site Assessment prepared by Peer Environmental &
Engineering Resources, Inc. ("Peer") dated February 9, 1999 with respect to the
Leased Real Property (the "Phase I").  Seller agrees that it shall, at Seller's
expense, retain Peer to conduct the Phase II subsurface investigation (the

conditions referenced in the Phase I, including, without limitation, the
potential for soil and/or groundwater contamination associated with the
underground storage tanks and septic system and the presence of acetone detected
from an on-site water well (the "Environmental Conditions").  The Phase II shall
be completed within 45 days after the Closing.  Notwithstanding anything herein
to the contrary, Seller shall, at Seller's expense, undertake such remedial
actions as may be recommended by Peer or otherwise required by Environmental
Laws with respect to any matters addressed in the Phase II, and shall indemnify
and hold Buyer and the Corporation harmless with respect to all Damages arising
out of or related to such Environmental Conditions or other matters addressed in
the Phase II and any remediation of the same, including any required or
recommended ongoing monitoring costs.  In addition, Seller, at Seller's expense,
shall immediately register all underground storage tanks located on the Leased
Real Property.  Seller's obligations set forth in this Section 6.17 shall
survive the Closing Date indefinitely, shall not be subject to the limitations
in Section 5.3 or 6.1 and shall be in addition to Seller's obligations in
Article V.

investment accounts in an amount of at least $1,575,000 as of the Closing. 
Neither Seller nor any officer or employee of the Corporation has made a
withdrawal, written a check or otherwise directed that such cash be distributed
from the Corporation.  Any breach of the representations in this Section 6.18
shall not be subject to the limitations set forth in Article V.

     1.2.  DEFINITIONS.  The definition of "Eligible Account Receivable"

     after this Amendment is otherwise effective and after completion of a
     collateral audit of Taurus that is satisfactory to the Lender.  The
     definition of "Term Note B" is deleted from the Credit Agreement. The
     definitions of "Term Notes" and "Term Note A" in Section 1.1 of the Credit
     Agreement are amended to read as follows:

           "TERM NOTE": Term Note A.

           "TERM NOTE A": As defined in Section 2.1.2.

     1.3   MORE DEFINITIONS.  The following definitions are added to Section
     1.1 of the Credit Agreement in appropriate alphabetical order:

           "FOURTH AMENDMENT": The Consent and Fourth Amendment to this Credit
and Security Agreement dated as of February 15, 1999.

           "TAURUS": Taurus Numeric Tool, Inc., a Minnesota corporation.

     1.4   TERM LOAN.  Section 2.1.2 of the Credit Agreement is amended in
its entirety to read as follows:

     2.1.2 TERM LOAN.

     (a)  Subject to the terms and conditions of the Loan Documents and the
          Fourth Amendment, and in reliance upon the warranties of the Borrower
          set forth herein and in the other Loan Documents, the Lender agrees to
          make a term loan (the "Term Loan") to the Borrower on


                                       2
<PAGE>

          the effective date of the Fourth Amendment in the principal amount of
          $3,200,000. The Borrower shall execute and deliver to the Lender a
          promissory note payable to the Lender in the amount of the Term Loan
          ("Term Note A").

     (b)  Unless otherwise required to be sooner paid pursuant to this
          Agreement, the principal of the Term Loan shall mature and be payable
          in consecutive equal monthly installments of $38,096 of principal
          commencing August 31, 1999 and continuing on the last day of each
          month until the Termination Date, at which time all unpaid principal
          and all accrued and unpaid interest shall be due and payable.  Any
          principal of the Term Loan that is repaid may not be reborrowed except
          as provided in SECTION 2.1.2(c).  Interest on Term Note A shall be
          paid in accordance with SUPPLEMENT A.

          (c)  So long as there are no Revolving Loans outstanding, the
          Borrower may, upon one Business Day notice to the Lender, prepay the
          principal of the Term Loan in whole or in part without premium except
          as set forth in SUPPLEMENT A.  Any partial prepayment of principal of
          the Term Loan shall be in a minimum amount of the lesser of (i) the
          outstanding principal balance of the Term Loan and (ii) $25,000 or an
          integral multiple thereof, and shall be applied to the unpaid
          installments of the Term Loan in the inverse order of their
          maturities.  Any principal of the Term Loan which is prepaid under
          this Section 2.1.2(c) may be reborrowed so long as (x) no Event of
          Default or Unmatured Event of Default has occurred and is continuing
          and (y) a principal balance was outstanding under Term Note A prior to
          the requested reborrowing and subject to a reduction in the
          availability under Term Note A based upon its due amortization in
          accordance with the provisions of this Agreement.

          (d)  Any payment of the Term Loan may be made with the proceeds of a
          Revolving Loan only if, immediately before and after giving effect to
          such payment, no Event of Default or Unmatured Event of Default then
          exists or would result therefrom.

          (e)  On or before each Mandatory Prepayment Date the Borrower shall
          pay to the Lender an aggregate amount equal to 30% of the Excess Net
          Income for the applicable fiscal year, based on audited financial


                                       3
<PAGE>

          statements for such fiscal year, which payment shall be applied
          against the unpaid installments of the Term Loan in the inverse order
          of maturities, with all such payments made in accordance with the
          provisions of Section 2.10(a).  If Revolving Loan Availability on the
          Mandatory Prepayment Date is $500,000 or less, the prepayment required
          under this Section 2.1.2(e) shall be due and payable on the first
          Business Day on which the Revolving Loan Availability next exceeds
          $500,000.  In no event shall the amount of the Term Loan required to
          be prepaid under this Section 2.1.2(e) exceed $200,000 for any fiscal
          year.

     1.5  CONSTRUCTION.  All references in the Credit Agreement to "this
     Agreement", "herein" and similar references shall be deemed to refer to the
     Credit Agreement as amended by this Amendment.

     To induce the Lender to enter into this Amendment and to make and maintain
the Loans under the Credit Agreement as amended hereby, the Borrower hereby

          amount to those held by the Lender, in respect of "Eurocurrency
          Liabilities" as such term is defined in Regulation D of the Board. The

               numerically corresponding day in the calendar month at the end of
               such Interest Period) shall end on the last Eurodollar Business
               Day of a calendar month; and

                    (3)  Any Interest Period that would otherwise end after the

          adoption or making after such date of any interpretations, directives

     time) two Eurodollar Business Days prior to the date of the requested
     Advance if the Advance is requested as a Eurodollar Rate Advance and not
     later than 1:00 p.m. on the date of the requested Advance if the Advance is
     requested as a Reference Rate Advance.  Each request for an Advance shall
     specify (i) the date of the Advance, (ii) the amount of the Advance to be
     made on such date which shall be in a minimum amount of $5,000 for
     Reference Rate Advances, or $500,000 for Eurodollar Rate Advances or, if

     Advance is to be funded as a Reference Rate Advance or a Eurodollar Rate
     Advance, and (iv) in the case of a Eurodollar Rate Advance, the duration of
     the initial Interest Period applicable thereto.

          3.2  CONVERSIONS AND CONTINUATIONS.  On the terms and subject to the
     limitations hereof, the Borrower shall have the option at any time and from
     time to time to convert all or any portion of the Advances into Reference
     Rate Advances or Eurodollar Rate Advances, or to continue a Eurodollar Rate
     Advance as such; provided, however that a Eurodollar Rate Advance may be
     converted or continued only on the last day of the Interest Period
     applicable thereto and no Advance may be converted or continued as a
     Eurodollar Rate Advance if a Default or Event of Default has occurred and
     is continuing on the proposed date of continuation or conversion.  Advances
     may be converted to, or continued as, Eurodollar Rate Advances only in
     amounts of $500,000 or an integral multiple thereof.  The Borrower shall
     give the Lender written notice of any continuation or conversion of any
     Advance and such notice must be given so as to be received by the Lender
     not later than 3:00 p.m. (Minneapolis time) two Eurodollar Business Days
     prior to requested date of conversion or continuation in the case of the
     continuation of, or conversion to, a Eurodollar Rate Advance.  Each such
     notice shall specify (a) the amount to be continued or converted, (b) the
     date for the continuation or conversion (which must be (i) the last day of
     the preceding Interest Period for any continuation or conversion of
     Eurodollar Rate Advances, and (ii) a Eurodollar Business Day), and (c) in
     the case of conversions to or continuations as Eurodollar Rate Advances,

     notify the Lender of the continuation of any Eurodollar Rate Advance within
     the time required by this 


                                      4 -
<PAGE>

     Section, such Advance shall, on the last day of the Interest Period 
     applicable thereto, automatically be converted into a Reference Rate 
     Advance of the same principal amount.

     shall accrue and be payable on the Advances as follows:

               3.3 (a)   Each Eurodollar Rate Advance on the Revolving Loan

          sum of (i) the Adjusted Eurodollar Rate for such Interest Period, plus
          (ii) the Applicable Revolving Margin.

               3.3(b)    Each Reference Rate Advance on the Revolving Loan shall

          Applicable Revolving Margin.

               3.3(c) Each Eurodollar Rate Advance on the Term Loan shall bear

          Period applicable thereto at a rate per annum equal to the sum of (i)
          the Adjusted Eurodollar Rate for such Interest Period, plus (ii) the
          Applicable Term Margin.

               3.3(d) Each Reference Rate Advance on the Term Loan shall bear
          interest on the unpaid principal amount thereof at a varying rate per
          annum equal to the sum of (i) the Reference Rate, plus (ii) the
          Applicable Term Margin.

               3.3 (e)   Any Advance not paid when due, whether at the date
          scheduled therefor or earlier upon acceleration, shall bear interest
          until paid in full at the Default Rate, which shall be (i) during the
          balance of any Interest Period applicable to such Advance, at a rate
          per annum equal to the sum of the rate applicable to such Advance
          during such Interest Period plus 2.0%, and (ii) otherwise, at a rate
          per annum equal to the sum of the rate otherwise applicable to such
          Advance plus 2.0% per annum.

               3.3 (f)   Interest shall be payable (i) with respect to each
          Eurodollar Rate Advance having an Interest Period of three months or
          less, on the last day of the Interest Period applicable thereto; (ii)
          with respect to any Reference Rate Advance, on the last day of each

          Advances, on the Termination Date; provided that interest under
          Section 3.3 (e) shall be payable on demand.

          3.4  OPTIONAL PREPAYMENTS.   The Borrower may prepay Reference Rate
     Advances on the Revolving Loan, in whole or in part, at any time, without

     unpaid interest on the amount prepaid.  Each partial prepayment shall be in
     a minimum amount of $10,000 or, if more, an integral multiple thereof.
     Except upon an acceleration following an Event of Default or upon
     termination of the Credit in whole or as otherwise required under the
     Credit Agreement, the Borrower may pay Eurodollar Rate Advances only on the
     last day of the Interest Period applicable thereto.  Amounts paid (unless
     following an acceleration or upon termination of the Credit in whole) or
     prepaid on Advances under this Section 3.4 may be reborrowed upon the terms
     and subject to the conditions


                                      5 -

     and limitations of the Credit Agreement. Prepayment of the Term Loan is 
     also subject to the provisions of Section 3.13 below.

          3.5  INTEREST RATE NOT ASCERTAINABLE, ETC.  If, on or prior to the
     date for determining the Adjusted Eurodollar Rate in respect of the
     Interest Period for any Eurodollar Rate Advance, the Lender determines
     (which determination shall be conclusive and binding, absent error) that:

               (a)  deposits in dollars (in the applicable amount) are not being
          made available to the Lender in the relevant market for such Interest
          Period, or

               (b)  the Adjusted Eurodollar Rate will not adequately and fairly
          reflect the cost to the Lender of funding or maintaining Eurodollar
          Rate Advances for such Interest Period,

     the Lender shall forthwith give notice to the Borrower of such
     determination, whereupon the obligation of the Lender to make or continue,
     or to convert any Advances to, Eurodollar Rate Advances, as the case may
     be, shall be suspended until the Lender notifies the Borrower that the
     circumstances giving rise to such suspension no longer exist.  While any
     such suspension continues, all further Advances by the Lender shall be made
     as Reference Rate Advances.  No such suspension shall affect the interest
     rate then in effect during the applicable Interest Period for any
     Eurodollar Rate Advance outstanding at the time such suspension is imposed.

          3.6  INCREASED COST.  If any Regulatory Change:

               (a)  shall subject the Lender to any tax, duty or other charge
          with respect to its Eurodollar Rate Advances, its obligation to make
          Eurodollar Rate Advances or shall change the basis of taxation of
          payment to the Lender of the principal of or interest on Eurodollar
          Rate Advances or any other amounts due under this Agreement in respect
          of Eurodollar Rate Advances or its obligation to make Eurodollar Rate
          Advances (except for changes in the rate of tax on the overall net
          income of the Lender imposed by the jurisdiction in which the Lender's
          principal office is located); or

               (b)  shall impose, modify or deem applicable any reserve, special
          deposit, capital requirement or similar requirement (including,
          without limitation, any such requirement imposed by the Board, but
          excluding with respect to any Eurodollar Rate Advance any such
          requirement to the extent included in calculating the applicable
          Adjusted Eurodollar Rate) against assets of, deposits with or for the
          account of, or credit extended by, the Lender or shall impose on the
          Lender or on the interbank Eurodollar market any other condition
          affecting its Eurodollar Rate Advances or its obligation to make
          Eurodollar Rate Advances;

     and the result of any of the foregoing is to increase the cost to the
     Lender of making or maintaining any Eurodollar Rate Advance, or to reduce
     the amount of any sum received or receivable by the Lender under this
     Agreement or under the Note, then, within 30 days after demand by the
     Lender, the Borrower shall pay to the Lender such additional amount or
     amounts as will compensate the Lender for such increased cost or reduction.
     The Lender will promptly notify the Borrower of any event of which it has
     knowledge, occurring after the date hereof, 


                                      6 - 

<PAGE>

     which will entitle the Lender to compensation pursuant to this Section.
     A certificate of the Lender claiming compensation under this Section, 
     setting forth the additional amount or amounts to be paid to it hereunder 
     and stating in reasonable detail the basis for the charge and the method of
     computation, shall be conclusive in the absence of error.  In determining 
     such amount, the Lender may use any reasonable averaging and attribution 
     methods.  Failure on the part of the Lender to demand compensation for any 
     increased costs or reduction in amounts received or receivable with respect
     to any Interest Period shall not constitute a waiver of the Lender's rights
     to demand compensation for any increased costs or reduction in amounts 
     received or receivable in any subsequent Interest Period.

          3.7  ILLEGALITY.  If any Regulatory Change shall make it unlawful or
     impossible for the Lender to make, maintain or fund any Eurodollar Rate
     Advances, the Lender shall notify the Borrower, whereupon the obligation of
     the Lender to make or continue, or to convert any Advances to, Eurodollar
     Rate Advances shall be suspended until the Lender notifies the Borrower
     that the circumstances giving rise to such suspension no longer exist.  If
     the Lender determines that it may not lawfully continue to maintain any
     Eurodollar Rate Advances to the end of the applicable Interest Periods, all
     of the affected Advances shall be automatically converted to Reference Rate
     Advances as of the date of the Lender's notice, and upon such conversion
     the Borrower shall indemnify the Lender in accordance with Section 3.8.

          3.8  FUNDING LOSSES; EURODOLLAR RATE ADVANCES.  The Borrower shall
     compensate the Lender, upon its written request, for all losses, expenses
     and liabilities (including any interest paid by the Lender to lenders of
     funds borrowed by it to make or carry Eurodollar Rate Advances to the
     extent not recovered by the Lender in connection with the re-employment of
     such funds and including loss of anticipated profits) which the Lender may
     sustain:  (i) if for any reason, other than a default by the Lender, a
     funding of a Eurodollar Rate Advance does not occur on the date specified
     therefor in the Borrower's request or notice as to such Advance under
     Section 3.1 or 3.2, or (ii) if, for whatever reason (including, but not
     limited to, acceleration of the maturity of Advances following an Event of
     Default), any repayment of a Eurodollar Rate Advance, or a conversion
     pursuant to Section 3.7, occurs on any day other than the last day of the
     Interest Period applicable thereto.  The Lender's request for compensation
     shall set forth the basis for the amount requested and shall be final,
     conclusive and binding, absent error.

          3.9  DISCRETION OF LENDER AS TO MANNER OF FUNDING.  The Lender shall
     be entitled to fund and maintain its funding of Eurodollar Rate Advances in
     any manner it may elect, it being understood, however, that for the
     purposes of this Agreement all determinations hereunder (including, but not
     limited to, determinations under Section 3.8, but excluding determinations
     that the Lender may elect to make from the Telerate System, Inc. screen)
     shall be made as if the Lender had actually funded and maintained each
     Eurodollar Rate Advance during the Interest Period for such Advance through
     the purchase of deposits having a maturity corresponding to the last day of
     the Interest Period and bearing an interest rate equal to the Eurodollar
     Rate for such Interest Period.
     
          3.10 OVERDRAFT LOANS; OVER ADVANCES.  Overdraft Loans and Over
     Advances (including the Agreed Over Advance) shall bear interest at the
     rate(s) determined pursuant to SECTION 2.7 or SECTION 2.8 of the Credit
     Agreement, as applicable.

          3.11 COMMITMENT FEE.  The Borrower shall pay to the Lender a
     commitment fee for the period from the date hereof to the date the Credit
     terminates in an amount equal to .50% per annum on the average daily Unused
     Revolving Credit Amount.
     
          3.12 LETTER OF CREDIT FEES.  The Borrower shall pay the Lender, or any
     Affiliate, a commission on the undrawn amount of each Letter of Credit and
     on each L/C Draft accepted by the Lender, or such Affiliate, in an amount
     equal to 2.0% per annum.
     
          3.13 PREPAYMENT FEE.  Upon prepayment in full of the Term Loan
     pursuant to any third party refinancing of the same or in connection with a
     sale of the Borrower or substantially all of its assets, the Borrower shall
     pay to the Lender a prepayment fee in an amount equal to one percent (1%)
     of the outstanding principal balance of the Term Loan; PROVIDED, that if at
     the time of such prepayment the advance rate then applicable to Eligible
     Accounts Receivable pursuant to SECTION 2.2(a) of this Supplement A is less
     than 75%, the prepayment fee shall not be applicable.

     4.   ELIGIBLE ACCOUNT RECEIVABLE REQUIREMENTS.

          (a)  For Accounts Receivable which are due and payable in full within
     30 days of the date of the invoice evidencing such Account Receivable, such
     Account Receivable must not be unpaid on the date that is 60 days after the
     due date.  For Accounts Receivable which are due and payable in full within
     60, 90 or 120 days of the date of the invoice evidencing such Account
     Receivable, such Account Receivable must not be unpaid on the date that is
     30 days after the due date.

          (b)  If invoices representing 10% or more of the unpaid net amount of
     all Accounts Receivable from any one Account Debtor are unpaid more than
     the number of days set forth in SECTION 4(a) above for such Accounts
     Receivable, then all Accounts Receivable relating to such Account Debtor
     shall cease to be Eligible Accounts Receivable.

     5.   ADDITIONAL COVENANTS.  From the date of the Credit Agreement and
thereafter until all of the Borrower's Obligations under the Credit Agreement
are paid in full, the Borrower agrees that, unless the Lender shall otherwise
consent in writing, it will not, and will not permit any Subsidiary to, do any
of the following:

          5.1  NET WORTH.  Permit the Borrower's Net Worth at any time to be
     less than $7,000,000.    
     
          5.2  LIABILITIES TO NET WORTH RATIO.  Permit the ratio, as of the last

                                     LEASE

     THIS LEASE is made as of February 15, 1999, by and between RODNEY WINTER 
AND REBA WINTER, husband and wife ("Landlord") and TAURUS NUMERIC TOOL, INC., 
a Minnesota corporation ("Tenant").  

                                   RECITALS:

     Landlord is the fee owner of (a) certain real estate located at 18151 
Territorial Road, Osseo, Hennepin County, Minnesota as legally described on 
Exhibit A and depicted on Exhibit B (the "Land"), (b) the approximately 
twenty-eight thousand (28,000) square foot building and all improvements 
located on the Land (the "Building"), and (c) the fixtures and equipment 
located in the Building (the "Equipment").  The Building and Equipment are 
collectively referred to in this Lease as the "Improvements".  The Land, 
Building and Equipment are collectively referred to in this Lease as the 
"Premises".

     As of the date of this Lease, 100% of the capital stock of Tenant has 
been purchased from Rodney Winter by WSI, Inc., a Minnesota corporation, 
pursuant to the terms and conditions of that certain Stock Purchase Agreement 
dated as of the date of this Lease (the "Stock Purchase Agreement").

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

     1.   PREMISES.  Landlord hereby leases the Premises to Tenant and Tenant 
hereby leases the Premises from Landlord.   Landlord warrants and represents 
that they are the owner of the Premises, and that they have the full right 
and authority to enter into this Lease, and that there are no leases or other 
rights with respect to the Premises which conflict with the terms of this 
Lease.  Landlord hereby represents and warrants to Tenant, as follows:

          1.1. CONDITION.  The Premises are structurally sound and are in
     good condition and repair (ordinary wear and tear excepted), and all
     material mechanical, electrical, heating, air conditioning, sewer,
     water and plumbing systems are in proper working order.   

          1.2. CONDEMNATION.  No portion of the Premises is subject to any
     decree or order to be sold or is being condemned or otherwise taken by
     any public authority, nor has Landlord been notified of any proposed
     condemnation or other taking.  

          1.3. UTILITIES.  All utilities required for the current operation
     of the improvements on the Premises are installed and operating and
     Landlord has not 

<PAGE>

     received notice of actual or threatened reduction or limitation on 
     use of any utility service now supplied to the Premises.

          1.4. COMPLIANCE.  The zoning, deed restrictions, covenants and
     applicable laws and ordinances applying to the Premises permit the
     presently existing improvements and the continuation of the business
     presently being conducted on the Premises.

          1.5. FLOOD PLAIN/LANDFILL.  To the best knowledge of Landlord, no
     portion of the Premises is located in a flood plain or flood hazard
     area or in a designated wetlands area and no portion of the Premises
     has been used as a landfill.  

          1.6. ASSESSMENTS.  Landlord has not received notice of actual or
     threatened special assessments or reassessments of the Premises.

     2.   USE OF PREMISES.  Tenant may use the Premises for any lawful use.

     3.   TERM. This Lease shall be for a term ("Term") of three (3) years 
commencing on February 15, 1999 ("Commencement Date") and terminating 
February 14, 2002.  Tenant shall have the right, at its option, to renew the 
Term of this Lease under the same terms and conditions as provided in this 
Lease for three (3) consecutive periods of one (1) year each ("Renewal 
Term(s)").  To exercise a renewal option, Tenant must notify Landlord in 
writing of Tenant's election to so renew not later than sixty (60) days prior 
to the end of the Initial Term or any previously exercised Renewal Term.  
When used in this Lease, "Term" shall mean the Initial Term and any exercised 
Renewal Term.

     4.   BASE RENT.  During the Term of this Lease, Tenant shall pay 
Landlord as base rent for the Premises ("Base Rent") an annual amount equal 
to $106,800.00, payable in equal monthly installments of $8,900.00, payable 
in advance, on the first day of each month. The parties acknowledge that the 
Base Rent is equal to $3.81 per square foot as of the Commencement Date.

          4.1  DAILY BASE RENT PRORATION.  In the event this Lease shall
     commence on a date other than the first day of a month, Base Rent for the
     first month shall be prorated on a daily basis.

          4.2  BASE RENT ADJUSTMENTS.  If Tenant exercises its option to renew
     the Term of this Lease, Base Rent for each such Renewal Term(s) shall be
     adjusted to the then current fair market rent as hereinafter provided (the
     "Fair Market Rent").  Upon receipt of Tenant's notice to renew, Landlord
     and Tenant shall meet and use their best efforts to determine the Fair
     Market Rent.  If Landlord and Tenant are unable to agree upon a Fair Market
     Rent within thirty (30) days of Tenant's notice to renew, then such rent
     shall be determined as follows:

                                       2

<PAGE>

               A.   If Landlord and Tenant are unable to agree on Fair Market
                    Rent within said thirty (30) day period, then within five
                    (5) days thereafter, Landlord and Tenant shall each
                    simultaneously submit to the other, in a sealed envelope,
                    its good faith estimate of the Fair Market Rent.  If the
                    higher of such estimates is not more than one hundred five
                    percent (105%) of the lower of such estimates, then the Fair
                    Market Rent shall be the average of the two estimates.

               B.   If the Fair Market Rent is not resolved by such exchange of
                    estimates, then either Landlord or Tenant may, by written
                    notice to the other within ten (10) business days after the
                    exchange, require that the Fair Market Rent be determined by
                    an MAI appraiser as an arbitrator.  Within ten (10) business
                    days after such notice, the parties shall select a mutually
                    acceptable MAI appraiser with experience in real estate
                    activities, including at least ten (10) years' experience in
                    appraising similar space in the Osseo, Minnesota area.  If
                    the parties cannot so agree on an appraiser, then within a
                    second period of ten (10) business days, each shall select
                    an independent MAI appraiser meeting the aforementioned
                    criteria, and within a third period of ten (10) business
                    days, the two appointed appraisers shall select a third
                    appraiser meeting the aforementioned criteria, which third
                    appraiser shall determine the Fair Market Rent.  If one
                    party shall fail to make such appointment within said second
                    ten (10) business day period, then the appraiser chosen by
                    the other party shall be the arbitrator.

               C.   Once the arbitrator has been selected as provided for above,
                    within ten (10) business days the arbitrator shall select
                    one of the two (2) estimates of Fair Market Rent submitted
                    by Landlord and Tenant, which must be the one that is closer
                    to Fair Market Rent as determined by the arbitrator.  The
                    decision of the arbitrator shall be rendered in writing to
                    both Landlord and Tenant and shall be final and binding upon
                    them.  If the arbitrator believes that expert advice would
                    materially assist him, s/he may retain one or more qualified
                    persons, including but not limited to, legal counsel,
                    brokers, architects or engineers, to provide such expert
                    advice.  The party whose estimate is not chosen by the
                    arbitrator shall pay the costs of the arbitrator and of any
                    experts retained by the arbitrator.  Any fees of any counsel
                    or expert engaged directly by Landlord or Tenant, however,
                    shall be borne by the party retaining such counsel or
                    expert.

                                       3

     5.   REAL ESTATE TAXES.  Real estate taxes and installments of special

furnished to the Premises during the Term of this Lease, which payments shall

     of the Premises and all equipment in or on the Premises, specifically
     including without limitation, walls, ceilings and floors, electrical,

with Landlord that Tenant's use and occupancy of the Premises shall comply 
with any and all local, state and federal laws, ordinances, rules, 
regulations and requirements regarding the environmental condition of the 
Premises, provided, however, Tenant shall not be responsible for such 
compliance (and Landlord shall be responsible for such compliance) regarding

the Premises, except where the same result from the negligent or 

                                       4

<PAGE>

intentional acts or omissions of Tenant, or its employees, officers, 
directors, agents, contractors, or invitees.  

     10.  ALTERATIONS.  Tenant shall not make any alterations or additions to 
the Premises or affix any signs to the Premises without first obtaining 
Landlord's written consent, which consent shall not be unreasonably withheld 
or delayed.  Tenant shall not permit any laborer's, mechanic's, or 
materialmen's liens to attach to the Premises by reason of any such 
alterations or additions performed by or at the request of Tenant, provided, 
however, Tenant shall have the right to contest any mechanic's lien or other 
lien which attaches to the Premises, provided that Tenant provides Landlord 
with reasonable security for the same.

     11.  CASUALTY INSURANCE.  Tenant shall, at Tenant's sole cost and 
expense, keep the Building and Improvements now or hereafter located on the 
Premises insured against fire and such other hazards and risks customarily 
covered by the standard form of extended coverage endorsement and the risks 
of vandalism, malicious mischief and sprinkler leakage in an amount not less 
then the full replacement cost of the Building and Improvements.  Tenant 
shall, at Tenant's sole cost and expense, insure all Tenant's personal 
property in the same manner. Tenant shall provide Landlord with evidence of 
such insurance on an annual basis.  

     12.  LIABILITY INSURANCE.  Tenant shall, at Tenant's sole cost and 
expense, procure and maintain a Commercial General Liability Insurance 
policy, which policy shall include without limitation, coverage for bodily 
injury, property damage, personal injury, advertising injury, contractual 
liability (applying to this Lease), independent contractors, and 
products-completed operations liability, which policy shall (a) name Landlord 
as an Additional Insured and (b) have a total combined liability policy limit 
of at least $1,000,000.00 applying to liabilities for bodily injury, personal 
injury and property damage.  Tenant shall provide Landlord with evidence of 
such insurance on an annual basis.  

     13.  FIRE OR OTHER CASUALTY.

          13.1  REPAIR.  If the Premises are destroyed or damaged by fire, any
     action of the elements or other casualty, Landlord agrees, with reasonable
     dispatch after notice thereof, at its own cost and expense and with the
     benefit of any insurance proceeds, to restore the Premises to substantially
     the same condition as that existing as of the commencement of this Lease. 
     In such case, all Base Rent paid in advance shall be apportioned as of the
     date of the destruction or damage, and any Base Rent, additional rent or
     other charges thereafter accruing shall be equitably and proportionately
     suspended and adjusted according to the nature, extent and duration of the
     destruction or damage, pending completion of repairs, except that in the
     event the destruction or damage is so extensive as to make it unfeasible to
     conduct Tenant's business on the Premises, Base Rent, additional rent and
     other charges hereunder shall be completely abated until Tenant resumes the
     conduct of its business on the Premises or the repairs are completed,
     whichever event first occurs.

                                       5

<PAGE>

          13.2 TERMINATION.  Notwithstanding the provisions of Section 13.1 of
     this Lease, in the event the Premises are completely destroyed or damaged
     to an extent which requires repair or rebuilding which repair or rebuilding
     cannot be completed within 180 days from the date such repair or rebuilding
     is commenced, either Landlord or Tenant may terminate this Lease upon
     giving written notice thereof to the other at any time within thirty (30)
     days after the date of such destruction, and if the Lease be so terminated,
     all Base Rent, additional rent and other charges payable hereunder shall
     cease as of the date of destruction and any prepaid Base Rent shall be
     refunded.

     14.  ACCESS BY LANDLORD.  Landlord shall have reasonable access to the 
Premises during business hours for the purposes of examining the same, or to 
make any needed repairs, or alterations of the Premises which Landlord may 
see fit to make, but the making of any inspections, repairs or alterations 
shall not unreasonably interfere with the operation of Tenant's business.

     15.  RIGHTS TO CURE DEFAULTS.  In the event either party hereto fails, 
refuses or neglects to perform an obligation imposed on it pursuant to the 
terms of this Lease, the other party may, after reasonable notice to the 
party in default, cure such default.  In the event the default is by Tenant, 
the cost of curing such default shall be paid as additional rent due Landlord 
hereunder, together with interest on the amount paid by Landlord at the rate 
of eight percent (8%) per annum ("Default Interest").  In the event the 
default is by Landlord, the cost of curing such default, together with 
Default Interest shall be immediately payable to Tenant by Landlord and 
failure to so pay the same shall be a further default by Landlord pursuant to 
the terms of this Lease. Tenant may set off the cost of curing the default 
against future installments of rent due hereunder.

     16.  DEFAULT IN MONETARY PAYMENT.  If Tenant shall default in the 
payment of Base Rent or any part thereof or in the payment of additional rent 
or any part thereof or in the payment of any other monetary obligation or 
indebtedness owing by Tenant hereunder to Landlord, and Tenant fails to cure 
such default within ten (10) days after receipt of written notice from 
Landlord of the existence of such default, Landlord shall have the right to 
terminate this Lease without further notice to Tenant, as well as such other 
rights and remedies provided in this Lease or as the law permits.

     17.  DEFAULT BY TENANT OTHER THAN NONPAYMENT OF RENT.  If Tenant shall 
be in default in performing any of the terms and provisions of this Lease 
other than the provision relating to the payment of Base Rent, additional 
rent or other charges, Landlord shall give Tenant written notice of such 
default, and if Tenant shall fail to cure such default within thirty (30) 
days after the date of receipt of such notice (or shall fail in that time to 
commence to cure a default whose cure would require more than thirty (30) 
days and diligently prosecute such cure to a reasonably prompt conclusion ), 
then and in such event Landlord shall have the option of (a) curing such 
default on behalf of and for the account of Tenant, in which case the sum so 
expended by Landlord plus Default Interest shall be deemed to be additional 
rent and on demand 

                                       6

<PAGE>

shall be paid by the Tenant on the day when rent shall next become payable, 
or (b) terminating this Lease by serving written notice thereof on Tenant, as 
well as such other rights and remedies as this Lease and the law permits.

     18.  REMEDIES OF LANDLORD.  In the event Tenant defaults pursuant to 
this Lease, and such default is not cured as therein provided, then and in 
such event Landlord may, without further notice or demand:

          18.1 ENTRY ON PREMISES.  Enter into and upon said Premises or any part
     thereof, in the name of Tenant, and take absolute possession of the same
     fully and absolutely without such re-entry working a forfeiture of the
     rents to be paid or the covenants to be performed by Tenant for the
     remaining term of this Lease, and Landlord may lease or sublet the
     Premises, or any part thereof, on such terms and conditions and for such
     rents and for such terms as Landlord may reasonably elect, and after
     crediting the rent actually collected by Landlord from such reletting on
     all rentals stipulated to be paid under this Lease by Tenant from time to
     time, collect from Tenant any balance remaining due from time to time on
     the rent reserved under this Lease.  Notwithstanding anything in this Lease
     to the contrary, Landlord shall use reasonable effort to mitigate its
     damages in the event of default by Tenant.

          18.2 TERMINATION OF LEASE.  Declare this Lease forfeited and void, and
     thereafter re-enter and take full possession of the Premises as the owner
     thereof, free from any right or claim of Tenant or any person or persons
     claiming through or under the Tenant.

The rights, options, powers and remedies of Landlord under this Lease shall 
be cumulative and in addition to any other rights given to Landlord by law.

     19.  CONDEMNATION.  If the entire Premises shall be condemned, or sold 
under threat of condemnation, then this Lease shall terminate as of the date 
title shall vest in the condemnor, and any prepayment of rent by Tenant shall 
be refunded on a pro rata basis, and the parties hereto shall be released 
from any further obligations hereunder.  If a substantial part of the 
Premises or a portion thereof which impairs Tenant's use of the Premises for 
the business then conducted on the Premises shall be condemned or sold under 
threat of condemnation, either Landlord or Tenant may terminate this Lease 
upon not less than thirty (30) days notice in writing to the other party of 
its intention to do so, and upon the dates set forth in said notice, this 
Lease shall terminate in the same manner and with the same effect as if the 
date were fixed herein for the expiration of the Term. 

          19.1 REPAIR OF PREMISES.  In the event that a part of the Premises is
     condemned or sold under threat of condemnation and this Lease is not
     terminated by Tenant or Landlord as provided in this Section 19, then
     Landlord shall at Landlord's sole cost and expense, but only to the extent
     of the condemnation proceeds received by Landlord, make 

                                       7

<PAGE>

     all necessary repairs or alterations so as to constitute the remaining 
     Premises a complete architectural unit and the Base Rent and other charges 
     to be paid by Tenant pursuant to this Lease shall be adjusted so that 
     Tenant shall be required for the remainder of the Term, to pay for only 
     the actual square footage of the Premises remaining after the condemnation.

          19.2 CONDEMNATION PROCEEDS.  All condemnation proceeds or damages
     awarded for a taking under the power of eminent domain of all or any part
     of the Premises shall belong to and be the property of Landlord, provided,
     however, the parties specifically agree that Tenant shall be entitled to
     any award made for relocation of Tenant's business and depreciation or
     damage to and cost of removal of Tenant's personal property and trade
     fixtures. 

     20.  SUBORDINATION.  This Lease and all payments required hereunder 
shall be subject and subordinate to any mortgages, trust deeds or ground 
leases now or hereafter placed upon the Premises, and to any advances made 
thereunder, and to the interest thereon, and all renewals, replacements and 
extensions thereof. Upon written request by Landlord, Tenant shall execute 
and deliver a written agreement subordinating this Lease to any mortgage(s) 
encumbering the Premises, provided, however, any subordination shall be upon 
the express condition that the validity of this Lease shall be recognized by 
the mortgagee(s), and that, notwithstanding any default by the mortgagor with 
respect to a mortgage or any foreclosure of a mortgage, Tenant's possession 
and right of use under this Lease in and to the Premises shall not be 
disturbed by such mortgagee(s) unless and until Tenant shall breach any of 
the provisions hereof and this Lease or Tenant's right to possession 
hereunder shall have been terminated in accordance with the provisions of 
this Lease.

     21.  SURRENDER OF PREMISES.  Tenant shall, at the expiration or earlier 
termination of this Lease, surrender the Premises to Landlord in as good 
condition and repair as at the time Tenant took possession, except for (a) 
damage from normal wear and tear and (b) damage from an insured casualty. 
Notwithstanding the foregoing, Tenant may remove its trade fixtures and 
personal property from the Premises at the expiration or earlier termination 
of this Lease, whether or not the same are affixed to the Premises, provided 
Tenant repairs any damage caused by such removal.  

     22.  MEMORANDUM OF LEASE.  This Lease shall not be recorded, but at the 
request of either party a memorandum of lease of even date herewith 
describing the Premises and stating the Term, shall be prepared and executed 
by the parties and may be recorded by either party.

     23.  ASSIGNMENT.  Neither Landlord nor Tenant shall assign this Lease or 
sublet the Premises without the prior written consent of the other party, 
which consent shall not be unreasonably withheld or delayed.  Notwithstanding 
the foregoing, Landlord or Tenant may, without the consent of another party, 
assign this Lease to an entity which is owned or controlled by it.  For 
purposes of this Section 23, "control" shall mean more than a 50% ownership 
interest.

                                  PRESS RELEASE
WSI Industries, Inc. Acquires Taurus Numeric Tool, Inc.

Profitable, Growing Precision Machining Company Positions WSI in
Avionics/Aerospace Markets


LONG LAKE, Minn.--(BUSINESS WIRE)--Feb. 16, 1999-- WSI Industries, Inc. (Nasdaq
National Market: WSCI)--known previously as Washington Scientific Industries,
Inc.--today announced it has acquired the stock of Taurus Numeric Tool, Inc., a
specialized precision machining company serving the avionics, aerospace,
electronic and medical markets. The transaction was financed through cash and
debt.

Taurus had 1998 sales of approximately $7.5 million, compared to WSI's sales of
nearly $24 million in fiscal 1998. The company's largest customer is Rockwell
International Corporation, for which Taurus manufactures avionics related
components. Taurus will continue to be headquartered at its facility in Osseo,
Minnesota, a northwestern suburb of Minneapolis.

Taurus, which will be operated under its current management as a subsidiary of
WSI, is expected to contribute to the Company's consolidated earnings in fiscal
1999. Taurus has posted strong sales growth during the past three years.

Michael J. Pudil, president and chief executive officer, said the Taurus
acquisition represents an excellent opportunity for WSI, since it enables the
Company to enter an attractive new market and to further diversify its mix of
business. He said the new WSI unit has a skilled and capable organization and is
expected to make a positive contribution to the Company over the balance of
fiscal 1999.

Pudil added that this transaction is the result of a carefully planned growth
strategy by which the Company is pursuing strategic acquisitions in the highly
fragmented precision machining industry. He said the Company is evaluating
additional transactions that can provide the Company with new manufacturing
technologies, significant new customers and strong positions in attractive
markets.

WSI Industries, Inc. is a leading contract manufacturer that specializes in the
machining of complex, high-precision parts for a wide range of industries.
