Item Two. Acquisition or Disposition of Assets.

     Pursuant to the Agreement and Plan of Merger, which is attached hereto as
an exhibit, Registrant, effective October 1, 1995, acquired from the sole
shareholder thereof all of the outstanding capital stock of Aerometrics, Inc., 
a California corporation.

     The consideration paid by Registrant for the purchase of the capital stock
was a cash payment of $820,000 plus 146,789 unregistered shares of TSI 
Incorporated common stock.  Registrant assumed long term debt of $455,000 
owed by Aerometrics, Inc. to the sole shareholder which was paid at closing.
Registrant has also agreed to pay an additional $250,000 pursuant to a 
five-year consulting and noncompetition agreement with the sole shareholder
and has entered into an employment agreement with the sole shareholder.  The 
consideration paid was determined by arms-length negotiations between 
Registrant and the selling shareholder.  No prior relationship existed
between Registrant and Aerometrics, Inc. or their shareholders, directors, 
officers, and associates.

     For payment of the purchase price, Registrant applied its own
accumulated funds.  No loans or debt instruments were associated with this
transaction but Registrant has lines of credit available to cover short term
fluctuations in cash flow as may be required.

     Aerometrics, Inc. is a maker of instrumentation for flow and velocity
measurements and particle measurements for fluid mechanics research 
applications.  In its fiscal year ended December 31, 1994, sales were
approximately $7.0 million.

     Registrant intends to continue operations of Aerometrics, Inc.
in California with product lines being integrated with similar and
complementary product lines manufactured by Registrant at its Shoreview
location in Minnesota.

its shareholder is attached as Exhibit 2 to this current report on Form 8-K.

94086 (the "Company"), and WILLIAM D. BACHALO, an individual
residing at 14660 Saltamontes Way, Los Altos Hills,
California 94022 (the "Principal Shareholder").

                          RECITALS

     The Boards of Directors of TSI and Newco, TSI in its
capacity as a shareholder of Newco and the Principal

the mode of carrying the same into effect shall be as
follows:


                          ARTICLE I

                       PLAN OF MERGER

     SECTION 1.1  Actions to be Taken.  Upon performance of
all of the covenants and obligations of the parties
contained herein and upon fulfillment (or waiver) of all of
the conditions to the obligations of the parties contained
herein, at the Effective Time of the Merger (as hereinafter
defined) and pursuant to the Business Corporation Act of the
State of Minnesota (the "MBCA") and the California
Corporation Code (the "CCC"), the following shall occur:

     1.1.1     The Company shall be merged with and into
Newco, which shall be the surviving corporation (the

corporate organization of the Company shall cease at the
Effective Time of the Merger, and thereupon the Company and
Newco shall be a single corporation, the name of which shall
be Aerometrics, Inc.  Newco, as the Surviving Corporation,
shall succeed, insofar as permitted by law, to all of the
rights, assets, liabilities and obligations of the Company
in accordance with the MBCA and CCC.

     1.1.2     The Articles of Incorporation of Newco shall
be and remain the articles of incorporation of the Surviving
Corporation until amended as provided by law.

     1.1.3     The By-Laws of Newco shall be and remain the
by-laws of the Surviving Corporation until amended as
provided by law.

     1.1.4     Until changed in accordance with the articles
of incorporation and by-laws of the Surviving Corporation,
William D. Bachalo, Leroy M. Fingerson, and Lowell Nystrom
shall be the directors of the Surviving Corporation.

of incorporation and by-laws of the Surviving Corporation,
the following persons shall be the officers of the Surviving
Corporation:

          Name                Office

     Leroy M. Fingerson       Chairman
     William D. Bachalo       President
     Lowell Nystrom           Vice President, Treasurer and
                                Assistant Secretary
     Laura Cochrane           Secretary

     1.1.6     As soon as practicable after the terms and
conditions of this Agreement have been satisfied, and upon
consummation of the closing referred to in Article IX hereof
(the "Closing"), articles of merger consistent with this
Agreement in the form prescribed by, and properly executed
in a accordance with, the MBCA and the CCC, in form and
substance satisfactory to the parties hereto and providing
for immediate effectiveness of the Merger (the "Articles of
Merger"), shall be filed with the Secretary of State of the
State of Minnesota and the Secretary of State of the State
of California.  The Merger shall become effective on the
date on which the Articles of Merger are properly filed with
the Secretary of State of Minnesota pursuant to the MBCA, so
long as the Articles of Merger are filed with Secretary of
State of California within six months thereafter pursuant to
the CCC.  As used in this Agreement, the "Effective Time of
the Merger" shall mean the date of filing with the Secretary
of State of Minnesota.

     SECTION 1.2  Common Stock of Surviving Corporation.
Following the Effective Time of the Merger, each of the
issued and outstanding shares of common stock of Newco
shall, by virtue of the Merger and without any action on the
part of TSI continue to be outstanding shares of common
stock of the Surviving Corporation.  Each share shall be
fully paid and non-assessable.

     SECTION 1.3  Definitions.  For purposes of this
Agreement, the following terms shall have the following
meanings:

     1.3.1     The term "Average Price" shall mean the
average (rounded to the nearest penny) of each "Mid-Price"
(as defined herein) of TSI Common Stock during the Trading
Period (as defined herein).  The "Trading Period" shall mean
the period of forty (40) consecutive trading days ending on
and including October 2, 1995; provided, however, that if no
trades occur on any of such trading days, the trading days
on which no trades occur shall be disregarded and a
sufficient number of trading days on which trades did occur
and which immediately preceded the 40 consecutive trading
days shall be added to the Trading Period so that there will
be a total of 40 trading days on which trades occurred.  The
Mid-Price for those days shall be employed for the
calculations described herein.  For purposes of this
Agreement, the term "Mid-Price" on each trading day shall
mean the median between the high and the low trade prices
for all of the stock trades of TSI's Common Stock traded on
such trading day as quoted on the National Market System of
the National Association of Securities Dealers Automated
Quotation System (as reported in the Wall Street Journal).
No party hereto shall, or shall cause or solicit its
officers, directors, employees or agents to, make any trades
in TSI Common Stock that have the effect of materially
increasing the Average Price.

     1.3.2     The term "Number of Outstanding Shares" shall
be the number of issued and outstanding shares of the
Company Common Stock at the Effective Time of the Merger.

     1.3.3     The term "Cash Conversion Number" shall be
the dollar amount equal to the result obtained by dividing
an amount equal to (i) $1,045,000 (as it may be adjusted
pursuant to Section 1.6 hereof) less (ii) the Option
Payment, by the Number of Outstanding Shares.

     1.3.4     The term "Number of TSI Shares" shall mean
the number of TSI Shares to be issued in the Merger, which
number shall be the result obtained by dividing $1,600,000
(as it may be adjusted pursuant to Section 1.6 hereof) by
the Average Price.

     1.3.5     The term "Option Payment" shall mean the
dollar amount paid by the Company to buy out the option held
by Michael Houser as described in greater detail in Section
1A.1 hereof.

     1.3.6     The term "Share Conversion Number" shall be
the number (as it may be adjusted pursuant to Section 1.6
hereof) obtained by dividing the Number of TSI Shares by the
Number of Outstanding Shares.

     1.3.7     The term "Effective Date" shall mean October
1, 1995 effective as of the opening of business on said
date.

     SECTION 1.4  Cancellation or Conversion of Company
Common Stock.  As of the Effective Time of the Merger, by
virtue of the Merger and without any action on the part of
any Shareholders:

     1.4.1     Treasury Shares.  The Company has no treasury
shares.

     1.4.2     Conversion.  Except as provided herein with
respect to Dissenting Shares (as hereinafter defined) and
fractional shares, at the Effective Time of the Merger, each
share of Company Capital Stock, of no par value (the
"Company Common Stock") which is issued and outstanding
shall be converted into (i) a number of shares of the common
stock of TSI, $.10 par value ("TSI Common Stock"), equal to
the Share Conversion Number, (as it may be adjusted pursuant
to Section 1.6 hereof and subject to adjustment pursuant to
Section 1.5 hereof), and (ii) an amount of cash equal to the
Cash Conversion Number (as it may be adjusted pursuant to
Section 1.6 hereof).

     1.4.3     Fractional Shares.  In lieu of the issuance
or recognition of fractional shares of TSI Common Stock or
interests or rights therein, each holder of shares of
Company Common Stock to be converted into TSI Common Stock
pursuant to Section 1.4.2 hereof shall be paid an amount in
cash equal to such fraction multiplied by the Average Price.

     1.4.4     Surrender of Shares.  After the Effective
Time of the Merger, each holder of an outstanding
certificate or certificates theretofore representing shares
of Company Common Stock converted into TSI Common Stock
pursuant to Section 1.4.2 hereof ("Company Stock
Certificates"), upon surrender thereof either to TSI, its
representative or Norwest Bank, N.A.,  TSI's transfer agent
(the "Transfer Agent"), shall be entitled to receive
(subject to the escrow provisions hereinafter set forth) in
exchange therefor (i) the total  cash conversion amounts for
such shares pursuant to Section 1.4.2 hereof, (ii) any
payment due in lieu of fractional shares pursuant to Section
1.4.3 hereof, and (iii) a certificate or certificates
representing the number of whole shares of TSI Common Stock
into which the shares of Company Common Stock theretofore
represented by such surrendered certificate or certificates
shall have been converted pursuant to Section 1.4.2 hereof.
TSI shall immediately wire the funds representing the cash
conversion amount to which the Principal Shareholder is
entitled at Closing upon receipt of the certificates of the
Principal Shareholder.

     Until so surrendered, each outstanding Company Stock
Certificate shall be deemed for all purposes, other than as
provided below with respect to the payment of dividends or
other distributions, if any, in respect of TSI Common Stock,
to represent the cash conversion amounts for the shares
represented by the certificate plus the number of whole
shares of TSI Common Stock into which the shares of Company
Common Stock theretofore represented thereby shall have been
converted.  Until so surrendered, TSI may, at its option,
refuse to pay any dividend or other distribution, if any,
payable to the holders of shares of TSI Common Stock to the
holders of Company Stock Certificates; provided, however,
that upon surrender and exchange of such Company Stock
Certificates there shall be paid to the record holders of
the TSI stock certificates or certificates issued in
exchange therefor the amount, without interest, of dividends
and other distributions, if any, which have become payable
and which have not previously been paid with respect to the
number of whole shares of TSI Common Stock then issued,
together with, without interest, any payment for fractional
shares required by Section 1.4.3 hereof, and, without
interest, the cash conversion amount for the shares of
Company Common Stock.

     Whether or not a Company Stock Certificate is
surrendered, from and after the Effective Time of the Merger
such certificate shall under no circumstances evidence,
represent or otherwise constitute any stock or other
interest whatsoever in the Company, the Surviving
Corporation or any other person, firm or corporation other
than TSI or its successors.

     1.4.5     Dissenters.  The shares of Company Common
Stock held by those shareholders of the Company who have
timely and properly exercised their dissenters' rights in
accordance with the provisions of the CCC applicable to
dissenters' rights (the "Appraisal Laws") are referred to
herein as "Dissenting Shares".  Each Dissenting Share, the
holder of which, as of the Effective Time of the Merger, has
not effectively withdrawn or lost his dissenters' rights
under the Appraisal Laws, shall not be converted into or
represent a right to receive TSI Common Stock and the cash
conversion amounts in the Merger, but the holder thereof
shall be entitled only to such rights as are  granted by the
Appraisal Laws.  Each holder of Dissenting Shares who
becomes entitled to payment for his Company Common Stock
pursuant to the provisions of the Appraisal Laws shall
receive payment therefor from the Surviving Corporation from
funds provided by TSI (but only after the amount thereof
shall have been agreed upon or finally determined pursuant
to such provisions).  If any holder of Dissenting Shares
shall effectively withdraw or lose his dissenters' rights
under the Appraisal Laws, such Dissenting Shares shall be
converted into the right to receive TSI Common Stock and the
cash conversion amounts in accordance with the provisions
hereof.

     1.4.6     TSI Certificates.  At or before the Effective
Time of the Merger, TSI shall make available to the Transfer
Agent certificates for such number of shares of TSI Common
Stock as shall be required for exchange in accordance with
this Agreement.  If, pursuant to the adjustment provided by
Section 1.6 hereof, additional shares of TSI Common Stock
must be issued, TSI shall make additional certificates
available to the Transfer Agent.

     SECTION 1.5  Adjustments for TSI Stock Splits, Etc.  In
the event that, subsequent to the date of this Agreement but
prior to the Effective Time of the Merger, the outstanding
shares of TSI Common Stock shall have been increased,
decreased, changed into or exchanged for a different number
or kind of shares or securities and such increase, decrease,
change or exchange shall have been effected through a stock
dividend, stock split or reverse stock split, then an
appropriate and proportionate adjustment shall be made in
the manner in which the Share Conversion Number is
calculated hereunder.

     SECTION 1.6  Adjustments to Merger Consideration Based
on Company's Closing Book Value.  The parties have agreed
that the total merger consideration (hereinafter the "Merger
Consideration") would have a value (the "Target Value")
equal to $2,645,000 less the Option Payment, based on the
assumption that the net book value determined in accordance
with generally accepted accounting principles, (the "Closing
Book Value") of the Company effective as of the Effective
Date would be $1,630,000 less the Option Payment.  At the
Target Value, the Merger Consideration consists of cash of
$1,045,000 less the Option Payment, and TSI Common Stock
having a total value, based on the Average Price, of
$1,600,000.

     If the Closing Book Value is greater than an amount
equal to (i) $1,830,000 less (ii) the Option Payment, then
the Merger Consideration shall be increased by consideration
having a value (the "Increased Value") equal to the excess
over said amount.  If the Closing Book Value is less than an
amount equal to (i) $1,430,000 less (ii) the Option Payment,
then the Merger Consideration shall be reduced by
consideration having a value (the "Decreased Value") equal
to the deficit below said amount.  If the Closing Book value
is from $1,430,000 less the Option Payment, to $1,830,000
less the Option Payment, inclusive (the "Range"), no
Adjustment shall be made.

     1.6.1     Proportionate Among Cash and Shares.  Where
consideration equal in value to the Increased Value or the
Decreased Value is added to or subtracted from the Merger
Consideration, then the increase or decrease, as the case
may be, shall be made by a combination of cash and TSI
Common Shares in the same proportion in which cash and TSI
Common Shares compose the Merger Consideration at the Target
Value.  The TSI Common Shares will be valued at the Average
Price for purposes of any adjustments made.

     1.6.2     Determination of Closing Book Value.
Promptly after the Closing Date (as hereinafter defined),
the Company, in cooperation with Purchaser, shall prepare
its financial statements (the "Closing Statements") for the
period ending the Effective Date, including preparation of
the balance sheet and statement of income and retained
earnings for the period beginning January 1, 1995 and ending
on the Effective Date.  Said financial statements will
consist of a balance sheet and a statement of operations,
and shall be prepared in accordance with generally accepted
accounting principles, subject, however, to the specific
provisions set forth below.  Representatives (the
"Representatives") of the former shareholder(s) of the
Company (such representative shall be the Principal
Shareholder unless he designates another person or persons)
and of TSI shall be entitled to witness and/or participate
in any actions material to the preparation of the Closing
Statements such as e.g., the counting and valuation of
inventory, verification of accounts receivable, and the
like.

     In preparing the Closing Statements, the following
specific provisions shall govern, even if following such
provisions would not be in accordance with generally
accepted accounting principles:

     (a)  The 4 Units at Dow.   Prior to the date hereof,
          the Company has delivered 4 Units of its Eclipse
          particle analyzer product to Dow Chemical ("Dow"),
          three at Dow's Midland Michigan location, and one
          at Dow Canada.  However, the Company has not yet
          invoiced the 4 Units to Dow because the Company
          has not received a purchase order from Dow.  If,
          within the time period commencing on the date
          hereof and ending on the date the Closing
          Statements are first completed (i.e., before the
          review period starts) the Company receives a
          purchase order from Dow which permits the Company
          to invoice some or all of the 4 Units, the Company
          shall issue an invoice therefor and the amount
          that is invoiced shall be treated as a receivable
          for purposes of determining the Closing Book
          Value.  To the extent the Company is not able to
          invoice some or all of the 4 Units within said
          time period, the Units not invoiced shall be
          valued in accordance with generally accepted
          accounting principles, taking into account, inter
          alia, a possible requirement to treat the Units as
          demonstration or development Units, and, if the
          Units are or can be made saleable, any
          expenditures required in order to put them in such
          saleable condition.

     TSI and the Company will use their best efforts to have
said financial statements including the Closing Balance
Sheet completed no later than 45 days after the Closing
Date.  Following completion of the financial statements, the
Representatives of TSI and the former Shareholder(s) shall
have twenty days to review said financial statements and all
documents and information relevant to the preparation of and
supporting said financial statements.  Following the
completion of said twenty-day period, the Representatives
shall meet and determine whether they agree with the Closing
Book Value as shown on such annual statements.

     If the Representatives agree, the Closing Book Value
shall be utilized to make adjustments, if any are required,
in accordance with this Section 1.6.  If the Representatives
do not agree then they shall, for a period of ten days
commencing at the end of the twenty-day period, negotiate in
an effort to reach agreement as to the Closing Book Value.

     If they are unable to reach such agreement, then the
Representatives shall appoint an independent and qualified
firm of certified public accountants to resolve any disputed
items (the "Independent Accountant").  A "big six" firm
which does not provide services, and has not within the
preceding three years provided services, to either of the
Company or TSI shall be utilized.  TSI and Dr. Bachalo shall
agree upon the firm to be utilized subject to the foregoing
requirements.  The firm which is selected shall thereupon
attempt to resolve all disputed items within thirty (30)
days after said firm's selection, and the recommendations
made by said firm shall be final.  The expenses charged by
said firm shall be borne equally by TSI and the former
Shareholders of the Company.

     1.6.3     Closing Based on Target Value; Escrow.  The
closing of the transactions provided hereby shall be made on
the assumption that the Closing Book Value will be within
the Range, so the value of the Merger Consideration will be
$2,645,000 less the Option Payment.  To that end, TSI will
deliver cash equal to $1,045,000 less the Option Payment at
the Closing, to be paid as described below, and will direct
the Transfer Agent to have certificates prepared for TSI
Common Shares having a value, based on the Average Price, of
$1,600,000.

     As described in Section 11.2 hereof, an escrow (the
"Escrow") is being established to provide for
indemnification claims, if any, which TSI may have against
the former Shareholders of the Company.  Said escrow shall
also be utilized to provide for the Purchase Price
Adjustment described herein.  To that end, at the Closing,
(i) $300,000 of the cash payable at Closing will be paid
into the Escrow, and (ii) stock certificate(s) representing
fifteen percent of the Number of TSI Shares (based on the
Target Value) (the "Escrowed Shares") will also be delivered
to the Escrow Agent, to provide both for any Purchase Price
Adjustment pursuant to this section and for any
indemnification claims.

     After the Purchase Price Adjustment, if any, has been
finalized, and distributions or contributions, as provided
below, have been made from or to the Escrow, there shall
remain in Escrow to provide for any indemnification claims
(i) $100,000 in cash (the "Claims Cash") and (ii) a number
of TSI Shares having a value of $100,000, determined based
on the Average Price (the "Claims Shares").  (Hereinafter
the Claims Cash and the Claims Shares are sometimes
collectively referred to as the "Claims Amounts".)  The
Claims Amounts will remain in Escrow to be available for any
indemnification claims.

     1.6.4     Adjustments.  For the purposes of all
adjustments made pursuant to this Section 1.6.4, the TSI
Shares held in Escrow shall be deemed to have a value
determined based on the Average Price, notwithstanding the
fact that at the time such adjustments are made, shares of
TSI Common Stock may be trading at another value.

     If the Closing Book Value, as finally determined
pursuant to Section 1.6.2 (the "Final Value"), is within the
range, no adjustment shall be made to the Merger
Consideration.  In said event, the Escrowed Shares in excess
of the Claims Shares shall promptly be distributed to the
former Shareholder(s).  The cash held in Escrow in excess of
the Claims Cash shall promptly be distributed to the former
Shareholder(s).

     If the Closing Book Value, as finally determined,
results in a Decreased Value, then the total of such
Decreased Value shall be broken into a cash component and
TSI Common Shares, in the same proportion as these items
made up the Merger Consideration at the Target Value.  The
number of TSI Common Shares constituting the proportionate
part of the Decreased Value shall then be returned by the
Escrow Agent to TSI.  Any remaining TSI Common Shares held
by the Escrow Agent shall first be utilized to provide the
Claims Shares to be retained in Escrow, and any balance
remaining of the TSI Common Shares held by the Escrow Agent
shall be distributed to the former Shareholders of the
Company.  The cash component of the Decreased Value shall
promptly be paid by the Escrow Agent from the Escrow to TSI.
If the cash then remaining in the Escrow exceeds the Claims
Cash, the excess shall promptly be distributed to the former
Shareholders.  If the amount held in escrow is not
sufficient to provide in full for the Decreased Value and
the Claims Amounts, the former Shareholders of the Company
shall deliver the deficiency to TSI in the form of cash and
TSI Common Shares.

     If there is an Increased Value based on the final
determination of the Closing Book Value, all of the TSI
Common Shares held in the Escrow in excess of the Claims
Shares shall be distributed to the former Shareholders.  In
addition, TSI shall promptly direct the Transfer Agent to
issue to the former Shareholders that number of TSI Common
Shares which represents the proportionate amount of the
Increased Value.  TSI shall promptly pay the former
Shareholders an amount of cash representing the
proportionate amount of the Increased Value.  In addition,
the cash held in Escrow in excess of the Claims Cash shall
promptly be distributed to the former Shareholders.

     After the foregoing adjustments are completed, the
Claims Cash and the Claims Shares shall continue to be held
in Escrow to be available for any indemnification claims.

     1.6.5     Conforming Adjustments.  Following final
determination of Closing Book Value as provided above, the
various definitions contained herein which determine the
final Merger Consideration shall all be finalized based on
the final determination.  Thus, the definitions of the Cash
Conversion Number, the Number of TSI Shares, and the Share
Conversion Number shall all be appropriately adjusted.

     SECTION 1.7  Further Assurances.  From time to time, on
and after the Effective Time of the Merger, as and when
requested by TSI or its successors or assigns, the proper
officers and directors of the Company immediately before the
Effective Time of the Merger shall, at TSI's expense, and
for and on behalf and in the name of the Company, or
otherwise, execute and deliver all such deeds, bills of
sale, assignments and other instruments and shall take or
cause to be taken such further or other reasonable actions
as TSI or their respective successors or assigns may deem
necessary or desirable in order to confirm or record or
otherwise transfer to the Surviving Corporation title to and
possession of all the properties, rights, privileges,
powers, franchises and immunities of the Company and
otherwise to reasonably carry out fully the provisions and
purposes of this Agreement.

     SECTION 1.8  Effective Date.  Notwithstanding that the
Closing hereunder is held shortly after the Effective Date,
it is the intention of the parties that the transactions
provided for herein shall be treated as being effective for
all purposes on and as of the Effective Date.  To this end,
all benefits and burdens of the business of the Company from
and after the Effective Date shall be for the account of TSI
and Newco.  Consistent with the foregoing, any profits from
operations of the Company in the time period from the
Effective Date through the Closing Date (the "Stub Period")
shall be for the benefit of TSI and Newco, and any losses of
the Company during the Stub Period shall be for the account
of TSI and Newco.  Consistent with the foregoing, the
parties are determining the Closing Book Value as of the
Effective Date.  The parties agree to report the
transactions provided for herein consistent with such
Effective Date provisions, including for both book and tax
purposes.

                         ARTICLE IA
                              
              HOUSER OPTION; TAX DISTRIBUTIONS
                              
     SECTION 1A.1  Houser Option.  Michael Houser, an
employee of the Company ("Houser"), holds an option to
acquire 10,000 shares of Company Common Stock at a price of
$3.00 per share (the "Houser Option").  It is a condition to
TSI's and Newco's obligation to close hereunder, that (i)
prior to the Closing hereunder, the Company shall buy out
the Houser Option from Houser in return for a cash payment
(the "Option Payment") agreed upon between Houser and the
Company, so that the Houser Option is terminated and of no
further force and effect; and (ii) that in connection with
such buyout of the Houser Option, the Company shall obtain a
release from Houser of any claims Houser has or may have
under or in connection with the Option or with respect to
the shares of Company Common Stock which could have been
acquired pursuant thereto, which release shall be acceptable
in form and substance to TSI and to the Company.  Amounts
expended by the Company in order to buy out the Houser
Option shall be reflected in the determination of Closing
Book Value.

     SECTION 1A.2  Tax Distributions.  Since July 18, 1995,
the Company has not, and from and after the date hereof and
through the Effective Time of the Merger, the Company will
not, make any payments, transfers of property or
distributions of any kind, directly or indirectly, to or for
the Principal Shareholder, his spouse or relatives, except
for (i) payment of base compensation in the ordinary course
of business, (ii) reimbursement of reasonable business
expenses in the ordinary course of business, (iii)
reimbursements for payments by the Principal Shareholder for
his family medical, dental and vision insurance, which
reimbursements are approximately $1,667 per quarter (the
"Medical Reimbursements") and (iv) Tax Distributions, as
described and permitted below.

     Because the Company is taxed as an S-corporation under
federal law, and under corresponding provisions of
California law, the Company from time to time makes cash
distributions to Principal Shareholder to permit him to pay
the income taxes payable by him with respect to the income
of the Company attributable to him under the S-corporation
rules.  The Company has made (or will make) a distribution
to Principal Shareholder to enable him to pay estimated
taxes on or about September 15, 1995 (the "September
Distribution"), and at about the time of the final
determination of the Closing Book Value will make an
additional distribution, if required, to reflect the
Company's taxable income through the Effective Date (the
"Final Distribution").  (The September Distribution and the
Final Distribution are sometimes collectively referred to
herein as the "Tax Distributions".)  The Tax Distributions
are subject to the following requirements and limitations:
     
          (a)  Tax Distributions shall be calculated
     and determined based solely on the Company's
     income and other tax items for its taxable year
     (the "Stub Year") commencing January 1, 1995, and
     ending on the Effective Date.  No distributions
     can be made to provide for additional taxes, if
     any, attributable to prior periods.
     
          (b)  The amount of the Tax Distributions
     shall be calculated to reasonably estimate the
     taxes payable by Principal Shareholder with
     respect to the Company's taxable income and other
     taxable items for the Stub Year, including
     reflecting any tax effect of the buyout of the
     Houser Option.  Among other things, this will be
     based on a reasonable estimate of the combined
     rate of tax applicable to Principal Shareholder
     and his wife on their joint return, after taking
     into account any deductibility of federal taxes
     for state tax purposes and vice versa.  If the
     parties are unable to agree upon the amount of Tax
     Distributions, they shall be subject to resolution
     in the same manner as provided in Section 1.6.2
     with respect to Closing Book Value.
     
          (c)  The amount of the Tax Distributions
     shall be fully reflected in the determination of
     Closing Book Value.  Thus, the final Distribution,
     even though made after the Closing Date to permit
     more precise calculation, shall be deemed to have
     been made prior to the determination of Closing
     Book Value.

                         ARTICLE II

        REPRESENTATIONS AND WARRANTIES OF THE COMPANY
                AND THE PRINCIPAL SHAREHOLDER

     Except for exceptions set forth in reasonable detail in
Exhibit E attached hereto and referring to the warranty or
warranties to which the exception relates, the Company and
the Principal Shareholder, jointly and severally, but
subject to the limitations set forth in Article XI, hereby
represent and warrant to, and agree with, TSI and Newco as
follows:

     SECTION 2.1  Organization.  The Company is a
corporation, duly organized, validly existing, and in good
standing under the laws of the State of California, and has
all requisite corporate power and authority to own its
property and conduct the business in which it is engaged.
The Company has previously delivered to TSI copies of its
articles of incorporation and by-laws, neither of which has
been amended since the date of such delivery.

     SECTION 2.2  Capitalization.  The Company is authorized
to issue only 5,000,000 shares of Company Common Stock of no
par value.  No other shares of stock, common, preferred, or
otherwise, are authorized.  As of the date hereof, there are
100,000 shares of Company Common Stock issued and
outstanding (the "Outstanding Common Shares").  The
Outstanding Common Shares are owned as specified on Exhibit
A attached hereto.  None of the outstanding Common Shares
were initially issued on or after December 31, 1994.  All of
the Outstanding Common Shares have been fully paid, have
been validly issued, and are non-assessable.  Holders of the
Outstanding Common Shares do not have preemptive rights or
other similar rights.  The Company does not have any
treasury shares.

     Except for the Houser Option, the Company does not have
outstanding any options or warrants to purchase, or
contracts to issue, or contracts or any other rights
entitling anyone to acquire shares  of its capital stock of
any class or kind, or securities convertible into such
shares.  Immediately prior to the Effective Time of the
Merger, the outstanding shares of Company Common Stock shall
not exceed the above-mentioned 100,000 Outstanding Common
Shares.  The Company does not have in effect any stock
option or stock purchase plan.

     At the Closing and at the Effective Time of the Merger,
the Shareholders owning shares of Company Common Stock shall
have good and marketable title thereto, free and clear of
all claims, liens and encumbrances.

     SECTION 2.3  Subsidiaries, Etc.  The Company has no
equity interest in any corporation, partnership or other
entity, except only that the Company has made an $8,500
investment in Aerometrology in France.  The Company has no
further obligations to or with respect to Aerometrology.

     SECTION 2.4  Qualification.  The Company is qualified
to do business in the State of California, its state of
incorporation, and in the State of Texas.  The Company does
not have assets, facilities or employees located in any
state or country other than the State of California, except
that the Company maintains one employee in a small office in
Houston, Texas.

     SECTION 2.5  Financial Statements and Liabilities.

     2.5.1     Attached hereto as Exhibit B are the balance
sheets of the Company as of December 31, 1993 and December
31, 1994 and the statements of income and retained earnings
of the Company for the fiscal years ending on said dates
reviewed by Steven Stroll, Certified Public Accountant (the
"Annual Statements"), and the Balance Sheet of the Company
as of June 30, 1995, and the statements of income and
retained earnings of the Company for the fiscal period
ending on said date compiled by the Company (the "Interim
Statements").

     The Annual Statements fairly present, in all material
respects, the financial position of the Company as of the
dates indicated, and the results of operations of the
Company for the periods then ended.

     The Interim Statements fairly present, in all material
respects, the financial position of the Company as of the
dates indicated and the results of operations of the Company
for the period then ended.

     The Closing Statements, including but not limited to
the Balance Sheet as of the Effective Date included therein,
which are to be prepared in accordance with Section 1.6
hereof, will fairly present, in all material respects, the
financial condition and assets and liabilities of the
Company as of the date of said statements and the results of
operation of the Company for the period ending on said Date,
in accordance with generally accepted accounting principles
applied on a  consistent basis.


     2.5.2     As of the date of this Agreement, the Company
is not subject to and does not have (i) any indebtedness,
claim, obligation or liability required to be reflected on
the Company's Balance Sheet or in the footnotes thereto
where the same has been prepared in accordance with
generally accepted accounting principles, or, (ii) to the
best knowledge of the Company and the Principal Shareholder,
any other material liability of any kind or nature
whatsoever, whether absolute or contingent, liquidated or
unliquidated, due or to become due, accrued or unaccrued or
otherwise (hereinafter collectively "Liabilities"), except
(iii) as disclosed in the Interim Statement, (iv) for such
Liabilities that have arisen in the ordinary course of
business of the Company since the date of said Interim
Statement, none of which newly arisen Liabilities, when
coupled with any benefits or receivables arising in
connection with the incurrence of such Liabilities, have a
material adverse affect upon the Company, its assets,
business, or financial condition, and (v) as specifically
disclosed in this Agreement or in the Exhibits delivered
hereto.

     SECTION 2.6  Real Estate.  The Company does not own or
have title to any real estate, and has never owned or had
title to any real estate.  The Company does not lease any
real estate other than pursuant to one real estate lease
(the "Lease") for its facility in California, and a real
estate lease (the "Houston Lease") for its office space in
Houston, Texas, both of which Leases are listed on Exhibit
C, Leases and Contracts, attached hereto, true and correct
copies of which have been made available (including
providing a copy thereof to be retained by TSI) to TSI.
Other than pursuant to the Lease and the Houston Lease, and
pursuant to its previous lease (the Prior Lease") of real
estate located at 550 Del Rey Avenue, Sunnyvale, California
94086 (the "Prior Location"), the Company has not leased any
other real estate during the past five years.  The Company
and to the best knowledge of the Company and the Principal
Shareholder, the other party thereto is not in material
default under the Lease or the Houston Lease, and there are
no facts which, with notice and/or the passage of time,
would constitute such a default.  To the best knowledge of
the Company and the Principal Shareholder, all buildings
leased by the Company pursuant to the Lease are in good
condition, normal wear and tear excepted, and the heating,
air conditioning, plumbing and electrical systems of each
such building are in good operating order, ordinary wear and
tear excepted.  The Company has not received notice that
said buildings do not comply with municipal, state and
federal statutes, ordinances, rules and regulations
applicable to the construction of the buildings and their
actual use and, to the best knowledge of the Company and the
Principal Shareholder, the buildings comply in all material
respects with said statutes, ordinances, rules and
regulations.  No consent is required under the Lease or the
Houston Lease in connection with the Merger.

     SECTION 2.7  Leased Tangible Personal Property.  The
Company does not lease any personal property other than
pursuant to (i) leases in the ordinary course of business
which expire on not more than 30 days notice by the Company
without payment of any penalty or termination payment, and
(ii) leases ("Personal Property Leases") which are listed on
Exhibit C, true and correct copies of which have been made
available to TSI.  Each of the Company and, to the best
knowledge of the Company and the Principal Shareholder, the
other parties thereto is not in material default under any
of the Personal Property Leases, and there is no fact which,
with notice and/or passage of time, would constitute such a
default.  No consent is required under the Personal Property
Leases in connection with the Merger.

     SECTION 2.8  Assets.  The equipment, furniture,
computers, and other tangible personal property (other than
inventory) owned, leased or used by the Company in its
business is in good condition, normal wear and tear
excepted, and is in good operating order.  Exhibit D-1
attached hereto lists all furniture, equipment, and other
tangible personal property of the Company (other than
inventory and supplies) having an original cost of $500 or
more.  Exhibit D-1 also lists all equipment, furniture,
computers and other tangible personal property which (i) is
used by the Company or which is located on the Company's
premises and (ii) which is not owned by the Company, except
for items leased under Leases elsewhere disclosed herein and
except for normal personal property of employees.  Except
for sales of inventory and other dispositions of assets in
the ordinary course of business, since December 31, 1994, no
tangible assets (whatever their original cost) have been
transferred from the Company, whether by sale, dividend or
otherwise.

     SECTION 2.9  Intangibles.  Attached hereto as Exhibit
D-2 is an accurate and complete list of all of the following
types of intangible personal property owned or used (whether
by license or otherwise) by the Company in its business,
including all distributorship, franchise and license
agreements (whether the Company is the grantor or grantee of
such distributorship, franchise or license) (the "Intangible
Agreements"):  patents, patent applications, registered
trademarks and other material trademarks, trademark
applications, and material trade names (whether the Company
owns such items or is licensed to use them), excluding any
license agreement (and the patents, patent applications,
trademarks and trademark applications subject thereto) for
commercially available software purchasable for less than
$1,000.  The Company is the sole and exclusive owner of each
of said items of intangible personal property shown as owned
by it.  Said items represent the only intangible personal
property of the types listed above required by the Company
in order to operate the businesses presently conducted by
the Company.

     Except as set forth on Exhibit D-2, the Principal
Shareholder does not own any patents or registered
copyrights, or applications for the same, or any inventions
which are usable in the Company's business as presently
conducted.

     Except as set forth on Exhibit D-2, there are no
pending claims or demands against the Company with respect
to any of such items of intangible personal property, and no
proceedings have been instituted, are pending, or, to the
best knowledge of the Company and the Principal Shareholder,
have been threatened to terminate or cancel any Intangible
Agreements or which challenge the right of the Company with
respect to any of such intangible assets.  To the best
knowledge of the Company and the Principal Shareholder, (i)
the Intangible Agreements will be renewed at their next
expiration date, and (ii) the Company and its assets and
business and any part thereof, do not infringe the patent,
trademark, trade name, copyright, or the other rights of any
other person.  Except as set forth on Exhibit D-2, to the
best knowledge of the Company and the Principal Shareholder,
the Company has the unrestricted (but not necessarily
exclusive) right to use, free from any rights or claims of
others, all trade secrets and customer lists which it has
used or which it is now using in connection with the sale of
any and all products or services which have been or are
being sold by it.

     SECTION 2.10 Accounts Receivable and Inventory and
Backlog.

     2.10.1    Accounts.  All accounts receivable of the
Company reflected in the Closing Balance Sheet to be
included in the Closing Statements will have originated in
the ordinary course of its business, will be valid, and will
be fully collectible and not subject to any defense,
counterclaim or setoff, except and only to the extent of the
reserve against accounts receivable reflected in the Balance
Sheet included in the Closing Statements.

     2.10.2    Inventory.  Except and only to the extent of
any reserve against inventory reflected in the Closing
Balance Sheet included in the Closing Statements:  (i) all
inventory in the Company's possession is owned by the
Company and will be recorded on its books and records as of
the date of the Closing Statements, in accordance with
generally accepted accounting principles, in all material
respects, and (ii) all inventory reflected in the Closing
Balance Sheet to be included in the Closing Statements will
be valued at the lower of cost, calculated on a FIFO method,
or market.  No inventory in the Company's possession has
been consigned to the Company.

     2.10.3    Backlog.  Exhibit D-3 attached hereto sets
forth the Company's backlog as of the date indicated on such
Exhibit.  The Company's backlog is fairly and accurately
described on said Exhibit, and all items included in such
backlog reflect bona fide orders to the Company from
customers of the Company.  To the best knowledge of the
Company and the Principal Shareholder, the customers for
such orders do not intend to cancel such orders; provided,
however, it is understood that such orders are subject to
cancellation in the ordinary course of the Company's
business.

     SECTION 2.11  Title to Assets.  The Company has or will
have, as applicable, good and marketable title in and to all
of its property (i) reflected in the December 31, 1994,
balance sheet included with the Annual Statements plus all
assets purchased by the Company since December 31, 1994,
less all assets which the Company has disposed of in the
ordinary course of business since such date, and (ii) which
will be reflected in the Closing Balance Sheet which will be
included in the Closing Statements, which property in each
case is or will be free and clear of any security interests,
consignments, liens, judgments, encumbrances, restrictions,
or claims of any kind except (a) security interests listed
and described on Exhibit F attached hereto, (b) liens for
current taxes or assessments not yet due or delinquent, and
(c) and such other minor imperfections of title which do not
materially restrict or interfere with the Company's use of
such assets and which do not materially impair the value of
such assets to the Company.

     SECTION 2.12  Contracts.

     2.12.1    Contracts.  Exhibit C attached hereto lists,
and the Company has made available (including providing a
copy thereof to be retained by TSI) to TSI, true and
complete copies of, all of the following contracts or other
obligations to which the Company is a party or by which it
is bound:

          (a)  Employment agreements and any other contracts
     with or loans to any of the Company's Shareholders,

     distributors or sales representatives;

          (b)  Any employee benefit plan made available
     by the Company to any of its employees;

          (c)  Any collective bargaining agreement;

          (d)  Any contracts with customers
     specifically including, without limitation, all
     contracts with customers pursuant to which the
     Company is performing or will perform services for
     customers such as, but not limited, to contract
     research, together with lists of all such
     completed customer contracts, which impose any
     material liabilities upon, or reasonably could be
     expected to result in any material liabilities
     against, the Company, other than warranty
     obligations.

          (e)  Any deeds of trust, mortgages,
     conditional sales contracts, security agreements,
     pledge agreements, trust receipts, or any other
     agreements or arrangements whereby any assets of
     the Company are subject to a lien, encumbrance,
     charge or other restriction;

          (f)  Any loan agreements, letters of credit
     on which the Company could be obligated to
     reimburse the issuing bank, or lines of credit;

          (g)  Any contracts to which the Company is a
     party restricting the Company from doing business
     in any areas or in any way limiting competition
     and any contracts to which the Company is a party,
     including without limitation contracts with
     suppliers, which limit, restrict or transfer
     rights to any technology utilized or developed by
     the Company or which establish rights of a
     supplier or customer to a particular product
     marketed or being developed by the Company,
     excluding the license implied in any sale of
     product, and excluding any license for
     commercially available software purchasable for
     less than $1,000; for each such contract, Exhibit
     C briefly describes the restrictions or
     limitations contained in the contract;

          (h)  Other than purchase orders issued in the
     ordinary course of the Company's business, any
     contracts calling for aggregate payments by the
     Company in excess of $1,000 and which are not
     terminable without cost or liability on notice of
     90 days or less;

          (i)  Any joint venture, partnership or
     limited partnership agreement involving the
     Company;

          (j)  Any guarantees by the Company of the
     obligations of any other party except those
     resulting from the endorsement of customer checks
     deposited by the Company for collection;

          (k)  Any other contracts which may have a
     material impact on the Company's assets, results
     of operations or financial condition; and

          (l)  Any commitments to enter into any of the
     types of contracts and obligations referred to in
     this Section 2.12.1.

     The Company has not received notice of any material
default under any such contracts, obligations or
commitments, is not in material default under any such
contracts, obligations or commitments, and there are no
facts which, with notice and/or the passage of time, would
constitute such a default.  To the best knowledge of the
Company and the Principal Shareholder, no other party to
such contracts, obligations or commitments is in material
default and there are no facts which, with notice and/or the
passage of time, would constitute such a default.  No
consent is required under the contracts, obligations and
commitments referred to in this Section 2.12.1 in connection
with the Merger.

     2.12.2    Purchase Commitments.  None of the Company's
purchase commitments is substantially in excess of the
normal, ordinary, and usual requirements of the Company's
business or was made at any price substantially in excess of
then-current market price.

     2.12.3    Bids and Contracts.  Exhibit C-1 attached
hereto lists, and the Company has previously made available
to TSI true and complete copies of:

     (i)  All outstanding bids for sales of the Company's
          products or services which either are still open
          in accordance with their terms or which were
          issued on or after July 1, 1995 and were for an
          aggregate amount equal to or exceeding $30,000
          (but bids and price indications issued by
          representatives and distributors of the Company
          which have not been approved by the Company need
          not be listed); and
     
     (ii) Unfilled purchase orders from customers quoting
          prices for the Company's products or services.
     
     SECTION 2.13  Suppliers and Customers.  Attached hereto
as Exhibit G is a list setting forth all suppliers to the
Company who are significant to the Company, including
without limitation (i) all suppliers who have supplied
products and/or services to the Company in the 8-month
period beginning January 1, 1995, where the total
consideration payable to the supplier exceeded $2,000, and
(ii) to the best knowledge of the Company and the Principal
Shareholder, suppliers who are a sole source (i.e., a
supplier who could not be replaced on reasonably equivalent
terms by another supplier) for a special and/or critical
product supplied by them.  Exhibit  G also lists all open
ended purchase orders issued by the Company which exist on
the date hereof.  For these purposes, open-ended purchase
orders shall mean purchase orders or other contractual
arrangements providing for extended deliveries by the
supplier, multiple deliveries by the supplier, or which
provide for purchases of quantities significantly in excess
of those required in the normal course of business of the
Company.

     To the best knowledge of the Company and the Principal
Shareholder, none of the Company's current customers or
suppliers intends to terminate its relationship with the
Company or materially reduce the volume of its purchases
from the Company (subject, however, to the understanding
that certain customers of the Company may have made
significant purchases which they are not likely to repeat in
the near future because the purchase has satisfied their
requirements) or materially reduce the volume of amounts
supplied to the Company, whether as a result of the Merger
or otherwise.

     SECTION 2.14  Transactions with Directors, Officers,
Employees and Affiliates.    Excluding cash dividends to
shareholders and cash salaries, benefits and expenses paid
to the Principal Shareholder and his wife, all of which are
listed on Exhibit E, there have been no transactions since
January 1, 1995, between the Company and any director,
officer, employee or affiliate (as defined in Rule 405
promulgated by the SEC) of the Company, except on an arm's
length basis in accordance with normal business practices.
Since said date, none of the officers, directors, employees
or affiliates of the Company, or any member of the immediate
family of any such persons, has been a director of officer
of, or has had a material interest in, any firm,
corporation, association or business enterprise which during
such period has been a material supplier, customer or sales
agent of the Company or has competed to a material extent
with the Company.

     SECTION 2.15  Litigation.  There are no legal,
administrative, arbitration or other proceedings or claims
pending or, to the best of the Company's knowledge,

Principal Shareholder in this Agreement, and no
certification furnished or to be furnished by TSI to the
Company pursuant to this Agreement, contains or, if

Common Stock in favor of the Merger.

TSI shall use its reasonable best efforts (a) to cause to be
fulfilled and satisfied all of the conditions to the Closing
to be fulfilled and satisfied by it, and (b) to cause to be
performed all of the matters required of it or Newco at or
prior to the Closing.  TSI shall use its reasonable best
efforts to make all of its warranties and representations
contained in this Agreement (except those representations
and warranties which are expressly limited to a state of

the same effect as if the same had been made and this
Agreement had been dated as at the Closing.

     SECTION 5.2  Consents, Approvals and Filings.  TSI will
use its reasonable best efforts to obtain as promptly as
possible all necessary approvals, authorizations, consents,
licenses, clearances or orders of governmental and
regulatory authorities required in order for TSI and Newco
to perform its respective obligations hereunder.

     SECTION 5.3  Advice of Changes.  TSI will promptly
advise the Company orally and in writing of (i) any event
occurring subsequent to the date of this Agreement which
would render any representation or warranty of TSI contained
in this Agreement, if made on or as of the date of such
Agreement or the Closing Date, untrue, inaccurate or
incomplete in any material respect and (ii) any material
adverse change in the working capital, financial condition,
assets, liabilities (whether absolute, accrued, contingent
or otherwise), operating profits or business of TSI.

     SECTION 5.4  SEC Reports.  Between the date hereof and
the Closing Date, TSI shall timely file with the SEC (and,
contemporaneously with such filings, shall deliver to the
Company a copy of) all reports and statements required to be
filed by TSI under the 1934 Act.  None of such reports and
statements shall contain an untrue statement of a material
fact or shall omit to state a material fact required to be
stated therein or necessary to make the statements made
therein, in light of the circumstances under which they were
made, not misleading.

     SECTION 5.5  Company Employees.  After the Merger,
manufacturing operations of the Company will be moved to
TSI's facility in Minnesota.  This will result in the
termination of a number of the Company's employees.  Such
employees will be offered a severance package in accordance
with the terms set forth on Exhibit M attached hereto.
Subject to its normal policies and procedures relating to
its facilities, TSI intends to maintain a research operation
at the Company's facility in Sunnyvale, California.
Benefits for employees of the Company who continue with the
Company ("Continuing Employees") will be changed to be
consistent with TSI's benefits provided, as they may change
from time to time, subject, however, to appropriate review
by TSI to maintain good employee relations. Wherever
appropriate, taking into consideration the entire benefit
package to be provided to Continuing Employees, TSI will
consider past service with the Company when administering
the benefits provided to the Continuing Employees.

     SECTION 5.6  Loans; Line of Credit.  The Company
presently is indebted to Dr. Bachalo and/or his spouse,
Renate Bachalo under several loans which have an aggregate
principal amount of $455,000, which amount bears interest at
the rate of ten percent (10%) per annum (the "Loans").
Interest on the Loans is current.  At the Closing, TSI shall
cause the principal amount of the Loans to be repaid in full
to Dr. Bachalo and Renate Bachalo.

     The Company presently has a revolving line of credit
arrangement in place with Wells Fargo Bank.  The amount of
principal owed under the line of credit on October 2, 1995
was $ 184,592.  The maximum amount borrowable under the
line of credit is $500,000.  Within 20 days after the
Closing Date, TSI shall cause said line of credit to be
repaid in full  or otherwise obtain the release of Principal
Shareholder from his guarantee of such line of credit.

                         ARTICLE VI

                TSI SHARES AND REGISTRATIONS

     SECTION 6.1  Shares Not Registered; Investment Intent.
The TSI Common Shares to be issued in the Merger have not
been registered under the Securities Act of 1933 (the
"Securities Act") or any state securities laws.

     Such TSI Common Shares have not been registered under
the Securities Act or any state securities laws by reason of
their contemplated issuance in transactions exempt from the
registration requirements of the Securities Act.  TSI's
reliance upon these exemptions is predicated in part upon
the understanding that each recipient of TSI Common Shares
in the Merger understands and acknowledges that TSI Common
Shares will be acquired for each Recipient's own account,
and not with a view to, or for resale in connection  with
any distribution or public offering thereof.  The TSI Common
Shares may not be transferred or resold without (i)
registration under the Securities Act or any applicable
state securities laws, or (ii) an exemption from the
registration requirements of the Securities Act and
applicable state securities laws.  Although Rule 144
promulgated under the Securities Act by the Securities &
Exchange Commission (the "Commission") may permit sales at a
future date provided said Rule remains in effect, in any
event each Recipient may not sell any securities pursuant to
Rule 144 prior to the expiration of a period from time to
time set forth therein after such Recipient has acquired
such securities.  Any sales pursuant to Rule 144 can be made
only in full compliance with the provisions of Rule 144.

     Except as provided in Section 6.2, TSI has not agreed
to, and has no obligation to, file a registration statement
to permit sale of the TSI Common Shares received under or in
connection with this Agreement.

     At its election, TSI may require that each Recipient of
TSI Common Shares which have not been registered execute and
deliver to TSI an investment letter confirming that such TSI
Common Shares are being acquired for the Recipient's own
account and not with a view to, or for resale in connection
with, any distribution or public offering thereof, and
confirming that the TSI Common Shares cannot be transferred
or resold without (i) registration under the Securities Act
or any applicable state securities laws, or (ii) an
exemption from the requirements of the Securities Act and
applicable state securities laws.

     SECTION 6.2  Certain Registration Rights; Rule 144
Reporting. TSI shall provide to Principal Shareholder the
registration rights provided in Exhibit R attached hereto.

     With a view of making available to the Principal
Shareholder benefits of certain rules and regulations of the
Securities and Exchange Commission (the "SEC") which may
permit the sale of the TSI Common Shares received by the
Principal Shareholder hereunder to the public without
registration, TSI agrees to use its reasonable efforts to:

     (a)  Make and keep public information available, as
those terms are understood and defined in SEC Rule 144 or
any similar or analogous rule promulgated under the 1933
Act, at all times;

     (b)  File with the SEC, in a timely manner, all reports
and other documents required of the Company under the 1933
Act and 1934 Act;

     (c)  So long as Principal Shareholder owns any such TSI
Common Shares, furnish to Principal Shareholder forthwith
upon request:  a written statement by TSI as to its
compliance with the reporting requirements of said Rule 144,
the 1933 Act and the 1934 Act; a copy of the most recent
annual or quarterly report of TSI; and such other reports
and documents as Principal Shareholder may reasonably
request in availing himself of any rule or regulation of the
SEC allowing him to sell any such securities without
registration.

                         ARTICLE VII

         CONDITIONS TO OBLIGATIONS OF TSI AND NEWCO

(other than the exercise of dissenters' rights),

necessary for the consummation of the Merger or for
preventing the termination or material breach of any real

agreement of TSI or the Company which is material to the
business of TSI or the Company, or for preventing any
material loss or disadvantage to TSI or the Company, by
reason of the Merger, shall have been obtained; and no such
consents or approvals shall have imposed a condition to such
consent or approval which in the opinion of TSI is unduly
burdensome to the consolidated financial condition or
operations of TSI or to the Company's business.

     SECTION 7.5  Opinion of Counsel.  TSI and Newco shall
have received an opinion of Cooley, Godward, Castro,
Huddleson & Tatum, counsel to the Company, dated the Closing

form and substance of Exhibit N annexed hereto.

     SECTION 7.6  Certificates.  The Company and the

the Closing Date as though such representations and
warranties were made at such time (except as contemplated in
Section 7.1 hereof) and that the Company has performed and
complied in all material respects with all terms, covenants
and provisions of this Agreement required to be performed or

equivalent agreement) with employees providing for, inter
alia, confidentiality and grant of invention rights to TSI.
A copy of the standard TSI Agreement is attached hereto as
part of Exhibit P.

     SECTION 7.11  Environmental Survey.  If an

          (b)  any breach by the Company or the Principal
     Shareholder of any material covenant hereunder;

          (c)  all liabilities of the Company arising
     before the Effective Time of the Merger (whether
     absolute, accrued, contingent or otherwise)
     required to be reflected or disclosed on the
     Closing Balance Sheet and the notes thereto in
     accordance with generally accepted accounting
     principles, except for such Liabilities as are
     specifically reflected in the Closing Balance
     Sheet included in the Closing Statements and
     except for such Liabilities which are specifically
     disclosed in the Exhibits hereto, but only to the
     extent that the amount of any such liabilities
     would, if deducted from the Final Value, have
     resulted in, or increased, the Decreased Value as
     described in Section 1.6 hereof.
     
          (d)  Warranty expense with respect to
     products of the Company sold before the Effective
     Time of Merger but only to the extent that the
     aggregate amount of such warranty expense in any
     of the one year periods commencing on the
     Effective Time of Merger and its anniversaries
     exceeds two and one-half percent (2-1/2%) of the
     Company's sales for the one-year period ending on
     the Effective Time of Merger.  The amount of the
     warranty expense shall be determined based on
     TSI's standard method of determining such expense
     in the ordinary course of business, but the
     warranty expense (i) shall not include any travel
     expenses and (ii) shall not include any expenses
     in the nature of goodwill expenditures which are
     not required under the terms of the applicable
     warranty.  To the extent a breach of the
     representation and warranty set forth in Section
     2.23(b) hereof occurs and gives rise to warranty
     expense, this Section 11.1(d) shall be the
     exclusive measure of the amount of such warranty
     expense, if any, to be subject to indemnification
     by the Principal Shareholder.

     In the event of any claim by Indemnitees under this
Section 11.1, Indemnitees shall be entitled to exercise all
remedies provided by law and/or equity with respect thereto,
including exercising a right of offset against amounts due
Principal Shareholder.

     If the Closing hereunder is held, the Company and the
Surviving Corporation will have no liability with respect to
indemnification claims by the Indemnitees.  In such event,
the amounts held in escrow and the Principal Shareholder
shall be responsible for  all indemnification claims.

     SECTION 11.2  Escrow.  At the Closing, TSI and the
Principal Shareholder, as representatives of all the
Shareholders in the Company, shall enter into an Escrow with
a national or state chartered bank acceptable to the
parties, (the "Escrow Agent") all pursuant to an Escrow
Agreement substantially in the form attached hereto as
Exhibit S (with  such changes thereto as the Escrow Agent
may reasonably require).  The amounts of cash and TSI Shares
specified in Section 1.6 will be delivered to the Escrow
Agent at Closing.  As described in Section 1.6, said amounts
will be available for payment to TSI in the event of any
Decreased Value after the final determination of Closing
Book Value.

     Following completion of the adjustments to the purchase
price pursuant to Section 1.6, the Claims Cash and the
Claims Shares shall remain in Escrow as provided in Section
1.6 and shall be subject to claims by TSI.  The remaining
balance in Escrow shall be distributed on the second
anniversary of the Effective Time of Merger, subject to any
outstanding claims by TSI.

     SECTION 11.3  Procedure for Claims; Payment First Out
of Escrow.  Wherever the Indemnitees, or any of them, have a
claim for indemnification, they shall deliver notice of such
claim to the Principal Shareholder specifying the claim and
describing it in reasonable detail.

     It is specifically understood that to the extent the
Indemnitees are ultimately determined to be due any payments
upon indemnification claims, the first source for such
payment shall be the amounts held in Escrow, if any.  Only
after such amounts are exhausted shall the Indemnitees have
a right to directly recover from the Principal Shareholder.

     SECTION 11.4.  Limitations on Indemnification. Subject
to the proviso at the end of this Section, the
indemnification obligations of the Principal Shareholder are
subject to each of the following limitations, understandings
or qualifications:

          (a)  Each of the representations and warranties
     made by the Company or the Principal Shareholder in
     this Agreement shall survive for a period of two (2)
     years after the Effective Time of Merger, provided,
     however, that the representations and warranties made
     in Section 2.2 hereof (relating to capitalization and
     title), shall survive without limitation, the
     representations and warranties made in Subsections
     2.19.1(b), 2.19.2, 2.19.4, 2.19.5, 2.19.6, 2.19.7, and
     2.19.8 (relating to ERISA and related matters) and in
     Section 2.20 hereof (relating to taxes), shall survive
     until the applicable statutes of limitations relating
     to tax and employee benefit matters shall have expired,
     and the representations and warranties in Section
     2.18.1, but only insofar as they relate to
     Environmental Laws, 2.18.2 and 2.18.3 shall survive for
     a period of five (5) years after the Effective Time of
     Merger.  After the expiration date of any
     representations and warranties no claim for
     indemnification based on such representations and
     warranties may be asserted by the Indemnitees, except
     that claims first asserted in writing with reasonable
     detail before the expiration date may be pursued until
     they are finally resolved.

          (b)  No claim by Indemnitees for indemnification
     can be made unless and until the amount of damages
     incurred by the Indemnitees, in the aggregate for all
     claims asserted, exceeds $65,000, and Indemnitees may
     recover indemnifiable damages only to the extent that
     such damages exceed $65,000; provided, however, that
     damages under Section 2.2 hereof (relating to
     Capitalization and Title) may be recovered in their
     entirety;
     
          (c)  The total amount recoverable by Indemnitees,
     in the aggregate, shall not exceed $2,645,000 less the
     Option Payment;
     
          (d)  The Indemnitees shall not be entitled to
     recover under this Article XI to the extent that the
     claim is reimbursed by payments from insurance paid for
     by the Company prior to the Closing Date;
     
          (e)  Claims may be recovered under Section 2.5,
     relating to Financial Statements and Liabilities, only
     to the extent that the amount of such claim would, when
     deducted from the Final Value, result in, or increase,
     any Decreased Value as determined in accordance with
     Section 1.6;
     
          (f)  Where a claim is payable hereunder, Principal
     Shareholder at his election, may choose to pay up to
     one-half of the amount of such claim in the form of TSI
     Shares, which Shares shall be valued for these purposes
     at the Average Price, regardless of the price at which
     they then may be trading.
     
          (g)  This Article XI shall be the sole and
     exclusive remedy for any claim by any Indemnitee under
     or in connection with this Agreement (it being
     understood, however, that the limitations of this
     Article XI do not apply to any claims which may be made
     under or in connection with the Non-Compete or the
     Employment and Consulting Agreement).
     
Provided, however, that the foregoing limitations,
understandings and qualifications shall not apply and shall
not limit or restrict any claim for indemnification by any
Indemnitees where and to the extent that such claim arises
from a knowing and intentional misrepresentation of a
material fact by the Company or the Principal Shareholder or
a knowing and intentional omission of facts or information
necessary to make a material representation or warranty not
materially misleading by the Company or the Principal
Shareholder.

                         ARTICLE XII

                   INDEMNIFICATION BY TSI

     SECTION 12.1  Indemnification by TSI.  Subject to the
limitations set forth below, TSI hereby agrees that,
notwithstanding the Closing, the delivery of instruments of
conveyance, and regardless of any investigation at any time
made by or on behalf of any party hereto or of any
information any party hereto may have in respect thereof, it
will indemnify and hold the Company (but only up until
Closing), and the Shareholders of the Company (hereinafter,
collectively, "the TSI Indemnitees") harmless from and
against any and all liabilities,  losses, damages, claims,
deficiencies, costs and expenses (including, without
limitation, reasonable attorney fees and other costs and
expenses incident to any suit, action or proceeding) arising
out of or resulting from and will pay to the Indemnitees the
amount of damages suffered thereby together with any amount
which they or any of them may pay or become obligated to pay
on account of:

          (a)  the breach or inaccuracy of any warranty
     or representation by TSI herein;

          (b)  any breach by TSI or the Surviving
     Corporation of any material covenant or hereunder;

          (c)  Any income taxes alleged to be due from
     the Principal Shareholder with respect to the
     operations of the Company during the Stub Period
     (specifically excluding, however, any income taxes
     which are imposed as a result of the transactions
     provided for hereunder).

     In the event of any claim by Indemnitees under this
Section 12.1, TSI Indemnitees shall be entitled to exercise
all remedies provided by law and/or equity with respect
thereto.

     If the Closing hereunder is held, the Company shall no
longer benefit from the foregoing indemnification.

     SECTION 12.2  Procedure for Claims.  Wherever the TSI
Indemnitees, or any of them, have a claim for
indemnification, they shall deliver notice of such claim to
TSI specifying the claim and describing it in reasonable
detail.

     SECTION 12.3  Limitation on Indemnification.  Subject
to the proviso at the end of this Section, the
indemnification obligations of TSI are subject to each of
the following limitation, understandings or qualifications:

          (a)  Each of the representations and
     warranties made by TSI shall survive for a period
     of two (2) years after the Effective Time of
     Merger.  After the expiration date of such
     representations and warranties no claim for
     indemnification based on such representations and
     warranties may be asserted by the TSI Indemnitees,
     except that claims first asserted in writing with
     reasonable detail before the expiration date may
     be pursued until they are finally resolved.

          (b)  No claim by TSI Indemnitees for
     indemnification under clauses 12.1(a) and 12.1(b)
     can be made unless and until the amount of damages
     incurred by the TSI Indemnitees, in the aggregate
     for all claims asserted, exceeds $65,000, and TSI
     Indemnitees may recover indemnifiable damages only
     to the extent that such damages exceed $65,000.

          (c)  The total amount recoverable by TSI
     Indemnitees, in the aggregate, shall not exceed
     $2,645,000 less the Option Payment.
     
          (d)  This Article XII shall be the sole and
     exclusive remedy for any claim by any TSI Indemnitee
     under or in connection with this Agreement (it being
     understood, however, that the limitations of this
     Article XII do not apply to any claims which may be
     made under or in connection with the Non-Compete or the
     Employment and Consulting Agreement.

Provided, however, that the foregoing limitations,
understandings and qualifications shall not apply and shall
not limit or restrict any claim for indemnification by any
TSI Indemnitees where and to the extent that such claim
arises from a knowing and intentional misrepresentation of a
material fact by TSI or from a knowing and intentional
omission of facts or information necessary to make a
material representation or warranty not materially
misleading by TSI.

                        ARTICLE XIII

                  MISCELLANEOUS PROVISIONS

     SECTION 13.1  Amendment and Modification.  To the
fullest extent permitted by applicable law, this Agreement
may be amended, modified and supplemented with respect to
any of the terms contained herein by mutual consent of the
respective Boards of Directors of the Company and TSI, or by
their respective officers duly authorized by such Boards of
Directors, by an appropriate written instrument executed at
any time prior to the Effective Time of the Merger;
provided, however, that following an affirmative vote at the
Shareholders' meeting referred to in Section 4.12 hereof,
this Agreement may not be amended to reduce the
consideration payable in the Merger in respect of shares of
Company Common Stock without obtaining the approval of the
Company's Shareholders in the manner required by law.

     SECTION 13.2  Waiver of Compliance.  To the fullest
extent permitted by law, each of TSI, Newco and the Company

Board of Directors, by an instrument in writing extend the
time for or waive the performance of any of the obligations
of the other or waive  compliance by the other with any of
the covenants, or waive any of the conditions of its
obligations, contained herein; provided, however, that the
obtaining of the approval of the Shareholders referred to in
Section 7.4 shall not be waivable and provided further that
any instrument executed on behalf of TSI shall bind or
effect Newco in the same manner.  No such extension of time
or waiver shall operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.

     SECTION 13.3  Survival of Representations and
Warranties. The respective representations and warranties of
each party hereto contained herein shall not be deemed to be
waived or otherwise affected by any investigation made by
the other parties hereto.  The representations and
warranties of TSI, Newco and the Company contained herein or
in any document furnished pursuant hereto shall survive the
Merger, subject to the limitations of Articles XI and XII.

     SECTION 13.4  No Third Party Rights.  Except as
otherwise provided in this Agreement, nothing herein
expressed or implied is intended, nor shall be construed, to
confer upon or give any person, firm or corporation, other

security holders, any rights or remedies under or by reason
of this Agreement.

     SECTION 13.10  Counterparts.  This Agreement may be

     SECTION 13.12  Entire Agreement.  This Agreement
(including the Exhibits hereto and the documents referred to
herein, all of which form a part hereof) and the
confidentiality agreements delivered by TSI and the Company
to each other contain the entire understanding of the
parties hereto in respect of the subject matter contained
herein and supersede all prior agreements and understandings
between the parties with respect to such subject matter.
There are no restrictions, promises, representations,
warranties, covenants, or undertakings, other than those
expressly set forth or referred to herein or therein.

     SECTION 13.13  Expenses.  Whether or not the
transactions contemplated hereby are consummated, each of
the parties hereto shall pay its own expenses incurred in
connection with the authorization, preparation, execution or
performance of this Agreement and all transactions
contemplated hereby, including without limitation all fees
and expenses of agents, representatives, counsel and
accountants.  It is understood and agreed that if the Merger
is consummated as contemplated hereby, the expenses incurred
by the Company and the Shareholders of the Company may be
paid by the Surviving Corporation only to the extent that
such expenses are accrued as a liability in the Closing
Balance Sheet included in the Closing Statements.  Any
excess of such expenses over the amount accrued shall be the
responsibility of the Principal Shareholder, and shall not
be borne by the Surviving Corporation.

     SECTION 13.14  Reorganization.  The parties hereto
contemplate and intend that the transactions described
herein will be treated as a tax-free reorganization under
the provisions of Section 368 of the Internal Revenue Code.
The parties agree to cooperate with each other as reasonably
requested by the other party, to achieve this objective, but
neither party makes any representation or warranty to the
other regarding the tax treatment to be afforded to the

unreasonably withheld or delayed.

     SECTION 13.16  Arbitration.  Excluding matters to be
resolved by the Independent Accountant pursuant to Sections
1.6.2 and 1.A.2 where the Independent Accountant's decision
shall be final, in the event of any controversy, claim or
dispute arising out of this Agreement or the transactions
contemplated hereby, said controversy, claim or dispute
(hereinafter a "Matter"), provided the amount in dispute is
$200,000 and less, shall be settled by binding arbitration
in Hennepin County, Minnesota, in accordance with the rules
and procedures then obtaining of the American Arbitration
Association, and the award by the arbitrator shall be final
and binding and may be enforced in any court having
jurisdiction.  The parties shall make available to the
arbitrator all books, records and other information
requested by the arbitrator.  The arbitrator may, in his
discretion, and as a cost of arbitration, employ experts to
assist it in making its determination.  Each party shall
have access during normal business hours to such books,
records and other data as is reasonably necessary to analyze
the Matter in dispute with the right to copy any of the same
at its expense.  In any such arbitration, the prevailing
party shall be entitled to recover, in addition to the basic
award of the arbitrator, its reasonable costs and expenses
of the arbitration, including reasonable attorneys' fees and
reasonable travel expenses.  Where each party prevails in
matters contested in the arbitration, such costs and
expenses shall be borne in such proportion as the arbitrator
may determine, consistent with the principle that the
prevailing party should recover its costs and expenses of
arbitration.

     IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed as of the date and year first
written above.
