3.   Financing:

  On March 31, 2000, the Company issued 500,000 shares of the Company's Series C
Convertible Participating Preferred Stock to Industrial-Works Holding Co., LLC,
a wholly owned subsidiary of Glenmount International L.P. for $1.0 million.  The
Company issued a warrant to Industrial-Works to purchase 100,000 shares of
common stock  with an exercise price of $2.00 per share in connection with this
transaction. This resulted in a beneficial conversion feature charge of $250,000
reflected in the Consolidated Statement of Operations.

  On February 22, 2000, the Company issued 4,250,000 shares of Series B
Convertible Participating Preferred Stock (each share of which is initially
convertible into one share of Common Stock) to Industrial-Works Holding Co.,
LLC, a wholly owned subsidiary of Glenmount International L.P.  Industrial-Works
Holding Co., LLC, also received a warrant to purchase 500,000 shares of common
stock with an exercise price of $1.00 per share. The transaction was approved at
a special meeting of shareholders held on February 7, 2000.  The Company intends
to use the net proceeds for market expansion and new product development as well
as for working capital and general corporate purposes.

  On April 3, 2000, the Company announced a proposed stock rights offering for
shares of common stock in the Company. Under the terms of the offering, the
Company would grant each of its shareholders of record on April 14, 2000, the
non-transferable right to purchase one newly issued share of common stock for
$2.00 per share for each three shares of common stock, outstanding or issuable
on conversion of preferred stock outstanding, on the record date. The rights
would be exercisable for 30 days from the date issued. On April 7, 2000, the
Company filed, with the Securities and Exchange Commission, a registration
statement on Form S-2 with respect to this proposed offering.

                                      -5-

4.   Change in Nasdaq listing:

  As of May 1, 2000, the Company's stock listing was transferred to the Nasdaq
Small Cap Market as a result of falling below the Nasdaq National Market's
minimum net tangible asset listing requirement in the third quarter of 1999,
prior to the $4.25 million equity investment by Glenmount in February 2000.

5.   Workforce Reduction:

  On May 11, 2000, the Company reduced its workforce by approximately 20
positions.  The reduction represented 20% of the Company's employees.  The
reduction resulted in a charge of approximately $200,000 against earnings,
primarily for employee severance costs, which the Company will recognize in the
second quarter of 2000.

*Less than .5%.

  Net Sales.   The Company's net sales decreased $2.1 million, or 32%, to $4.3
million in the first quarter of fiscal 2000 from $6.4 million in the first
quarter of fiscal 1999.  The decrease was due to the delay of anticipated
customer orders and the postponement of the introduction of the 8000 Series
Workstation as the result of development and testing delays. Unit volumes of the
5000 Series Workstation increased to 40% in the first quarter of 2000 from 26%
in the first quarter of 1999.  Unit volumes of the 7000 Series Workstation
decreased to 33% in the first quarter of 2000 from 74% in the first quarter of
1999 due to customers awaiting the 8000 Series Workstation.   Sales of the 5000
Series Workstations represented 44% and 47% of net sales for the three months
ended April 2, 2000 and April 4, 1999, respectively.  Unit volumes of the 2000
Series Embedded Vehicle Server were 27% in the first quarter of 2000. Production
of the FW2000 began in mid-1999; therefore, there were no comparable sales in
the first quarter of 1999.

  The Company is targeting sales in trucking, heavy equipment, public services
and field technologies markets with emphasis on providing customer specific
solutions.  Two customers accounted for greater than 10% of net sales in the
first quarter of 2000, John Deere Information Systems and the City of Palm
Springs, represented $0.9 million and $0.5 million of the Company's net sales,
respectively.  One customer, Ryder Transportation Services, represented $2.6
million of the Company's net sales for the first quarter of 1999.

  International sales decreased to $0.7 million, or 15% of net sales, for the
first quarter of 2000 from $1.0 million, or 16% of net sales, for the comparable
period in 1999.  The decrease is due to the delayed introduction of the 8000
Series Workstation.  The majority of international sales, 67% and 75% of net
sales for the first quarter of 2000 and 1999, respectively, are in Europe.  The
Company believes that international sales, as a percentage of net sales, will
range from 15-20% for the remainder of 2000, with little impact on the Company's
results of operations or liquidity.

  Gross Profit.   Gross profit decreased to $1.0 million, or 22% of net sales,
for the first quarter of 2000 from $2.1 million, or 32% of net sales for the
first quarter of 1999.  Gross margin was negatively impacted by duplicative
manufacturing overhead costs due to transitioning to outsourcing in the first
quarter of 2000.  Gross margin was also negatively impacted by start-up costs
associated with the introduction of the FW8000 Series, lower margins on the 2000
Series Mobile Embedded Server and decreased revenue base in which to allocate
fixed overhead costs.  The

                                      -7-
<PAGE>

Company's gross profit margin will fluctuate as a result of a number of factors,
including mix of products sold, inventory obsolescence, the proportion of
international sales, large customer contracts (with the associated volume
discounts) and outsourcing expenses.

  The Company has outsourced the final assembly process during the first quarter
of 2000 and anticipates reducing inventory levels throughout the year 2000.
Repair and final integration work will remain at the Company for the near
future.  The Company anticipates outsourcing will moderately reduce future
material costs, inventory write-offs and operating expenses.  The Company
anticipates gross profit margins in the low 30% range in the near future.

  Sales and Marketing.   Sales and marketing expenses include salaries, sales
commissions, travel, technical support and professional services personnel,
advertising, promotions and trade shows.  In addition, these expenses include
the labor and material costs related to maintaining the Company's standard one-
year warranty on its products.  Sales and marketing expenses remained constant
at $1.0 million for the first quarter of 2000 and 1999.  As a percentage of net
sales, sales and marketing expenses increased to 22% for the first quarter of
2000 from 15% for the first quarter of 1999.  The Company plans to continue
expanding its resale channels through Value Added Resellers (VARs) as well as
moderately increase its advertising and promotion costs within its target
markets.  The Company anticipates growth of sales and marketing to be less than
the growth of sales in the future.

  General and Administrative.   General and administrative expenses include the
Company's executive, finance and administration, human resources, and
information services departments.  These expenses increased to $0.9 million for
the quarter ended April 2, 2000, from $0.7 million for the quarter ended April
4, 1999.  As a percentage of net sales, general and administrative expenses
increased to 20% for the quarter ended April 2, 2000, from 11% for the quarter
ended April 4, 1999.  The increase is primarily due to the fees associated with
the management services agreement with Glenmount International, L.P.  The
Company anticipates holding the percentage growth of general and administrative
expenses to a level less than the growth of sales in the future.

  Research and Development.   Research and development expenses are incurred in
the design, development and testing of new or enhanced products, services and
customized computing platforms.  These costs are expensed as incurred. Research
and development expenses increased to $1.1 million in the first quarter of 2000
from $0.9 million for the first quarter of 1999.   As a percentage of net sales,
research and development costs were 26% and 13% for the first quarter of 2000
and 1999, respectively.  The $0.2 million increase was primarily due to the
development of new products, including the FieldWorks 8000 Series Workstation
Platform and engineering support of customer-specific applications.
Additionally, the Company is incurring product re-design expenses to incorporate
embedded systems technology and reduce product costs.  The Company expects
research and development expenses to decrease as a percentage of net sales
through 2000 due to finalizing the 8000 Series Workstation and completing
product outsourcing.

  Interest Income (Expense) and Other, Net.   Net interest expense was
approximately $267,000 for the first quarter of 2000 compared to net interest
income of $2,000 for the comparable period in 1999.  The increase in interest
expense is due to borrowings on the Company's line of credit and interest
payments on its subordinated notes.  Additionally, financing costs of $882,000
related to warrants issued in September 1999 will be amortized over the next two
years.  The Company anticipates recording net interest expense for the
foreseeable future.

Liquidity and Capital Resources

  On April 3, 2000, the Company announced a stock rights offering for shares of
common stock in the Company.  Under the terms of the offering, the Company would
grant each of its shareholders of record on April 14, 2000, the non-transferable
right to purchase one newly issued share of common stock for $2.00 per share for
each three shares of common stock outstanding or issuable on conversion of
preferred stock outstanding, on the record date.  The rights would be
exercisable for 30 days from the date issued.  On April 7, 2000, the Company
filed, with the Securities and Exchange Commission, a registration statement on
Form S-2 with respect to this proposed offering.

  On March 31, 2000, in conjunction with the above-mentioned stock rights
offering, the Company issued 500,000 shares of the Company's Series C
Convertible Participating Preferred Stock to Industrial-Works Holding Co., LLC,
a wholly owned subsidiary of Glenmount International L.P. for $1.0 million.  The
Company recorded a

                                      -8-
<PAGE>

$250,000 charge relating to the beneficial conversion feature. The Company
issued a warrant to Industrial-Works to purchase 100,000 shares of common stock
with an exercise price of $2.00 per share in connection with this transaction.
If the Company does not close a stock rights offering with a minimum of $5
million in gross offering proceeds prior to June 30, 2000, the conversion rate
is adjusted to two shares of common stock for each share of Series C Convertible
Participating Preferred Stock.

  On February 22, 2000, the Company completed a $4.25 million equity investment
by Industrial-Works Holding Co., LLC, a wholly owned subsidiary of Glenmount
International L.P.  In exchange for the $4.25 million investment, the Company
issued 4,250,000 shares of Series B Convertible Participating Preferred Stock
(each share of which is initially convertible into one share of common stock).
Industrial-Works Holding Co., LLC, also received a warrant to purchase 500,000
shares of common stock at $1.00 per share.  The transaction was approved at a
special meeting of shareholders held on February 7, 2000.  The Company intends
to use the net proceeds for market expansion and new product development as well
as for working capital and general corporate purposes.

  In September 1999, the Company completed a private placement of $3.0 million
in subordinated notes.  The notes bear interest at 11% per annum and mature in
September 2001.  Noteholders also received warrants to purchase 1.5 million
shares of common stock exercisable at $1.00 per share.  The warrants are
exercisable for five years, and recorded at their estimated fair value at the
date of issuance.

  In November 1998, the Company entered into a two-year, $3.0 million line of
credit agreement.  Borrowings bear interest at the greater of 4% over prime or
9%. The interest rate changed from 3% over prime to 4% over prime in the third
quarter of 1999 due to default on the Company's profitability covenant.  At
April 2, 2000, the interest rate was 13%.  The line of credit balance was $0.6
million as of April 2, 2000, as compared to $1.8 million at January 2, 2000.
The borrowing base consists of 75% of eligible receivables plus the lesser of
$600,000 or 30% of eligible inventory as defined in the agreement.  Availability
based on the borrowing base calculation, including accounts receivable and
inventory, was $2.1 million as of April 2, 2000 and was $3.0 million as of
January 2, 2000.  The agreement contains a covenant requiring cumulative year-
to-date profit on a quarterly basis.  The Company was out of compliance with the
covenant as of April 2, 2000, and has received a written waiver of default.
Failure to comply with this covenant in the future could result in default,
interest rate increases and immediate repayment requirements.  The Company
intends to renew this agreement upon expiration or pursue a replacement source
of financing.  However, there can be no assurances that a credit agreement will
be available to the Company.

  Cash used for operating activities totaled $1.4 million for the first three
months of 2000.  The Company's accounts receivable decreased $1.1 million from
$5.1 million at January 2, 2000 to $4.0 million at April 2, 2000 due to timing
of increased sales at the end of the fourth quarter in 1999.  Inventories
increased slightly to $4.6 million at April 2, 2000, from $4.5 million at
January 2, 2000 due to continued purchases for anticipated sales in the first
and second quarters of 2000.

  During the first quarter of 2000, the Company purchased $0.2 million of
property, plant and equipment.  The expenditures related primarily to
manufacturing tooling for vendors of the Company's FW8000 Series Workstation
Platform.  The Company anticipates maintaining this level of tooling
expenditures in the foreseeable future, as new product line developments are
completed and existing platforms are enhanced. However, the Company's overall
property, plant and equipment expenditures are expected to decrease slightly as
compared to prior years due to no additional planned leasehold improvements.

  On April 28, 2000, the Company announced it has retained Goldsmith, Agio,
Helms & Lynner, Ltd., partially in response to a third-party inquiry, to assist
the Company in exploring strategic alternatives.

  The Company anticipates that the proceeds from its issuance of preferred
shares, together with its line of credit, and anticipated operating cash flows,
and proceeds from the alternative equity sources it is pursuing, should be
sufficient to fund its cash flow needs through the year 2000.  Cash requirements
for future periods depend on demand for the Company's products, cash management
operations, growth rate and acquisition strategies, among other factors. There
can be no assurances that additional financing, if needed, will be available, or
if it is available, that it would be on terms favorable to the Company and would
not be dilutive to existing shareholders.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

  The Company is exposed to market risk related to changes in interest rates on
borrowings under the Company's line of credit agreement.  The line of credit
bears interest based on the Prime Lending Rate.  At April 2, 2000, the Company
had $0.6 million outstanding.  Based on analysis, interest rate shifts would
have an immaterial impact on the Company.

  The Company has no derivative financial instruments or derivative commodity
instruments in its cash and cash equivalents.  The Company invests any excess
cash and cash equivalents in money market instruments.  The Company had $2.5
million in cash and cash equivalents at April 2, 2000.  Based on analysis,
shifts in money market rates would have an immaterial impact on the Company.

  All of the Company's transactions are conducted and accounts are denominated
in United States dollars and as such, the Company does not currently have
exposure to foreign currency risk.


PART II.  OTHER INFORMATION
- ---------------------------
ITEM 1.  LEGAL PROCEEDINGS

  The Company is involved in legal actions in the ordinary course of its
business. Although the Company cannot predict the outcome of any such legal
actions, management believes that there is no pending legal proceeding against
or involving the Company for which the outcome is likely to have a material
adverse effect upon the Company's financial position, results of operations or
cash flows.


ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

  On March 31, 2000, the Company issued 500,000 shares of the Company's Series C
Convertible Participating Preferred Stock to Industrial-Works Holding Co., LLC,
a wholly owned subsidiary of Glenmount International L.P., in exchange for $1.0
million.  The Company also issued a warrant to Industrial-Works to purchase
100,000 shares of common stock.

  On February 22, 2000, the Company issued  4,250,000 shares of the Company's
Series B Convertible Participating Preferred Stock to Industrial-Works Holding
Co., LLC, a wholly owned subsidiary of Glenmount International L.P., in exchange
for $4.25 million.  The Company also issued a warrant to Industrial-Works to
purchase 500,000 shares of common stock.

  Each share of Series B and Series C Preferred Stock is initially convertible
into one share of common stock.  The Company intends to use the net proceeds for
market expansion and new product development as well as for working capital and
general corporate purposes.

  In September 1999, the Company completed a private placement of $3.0 million
in subordinated notes.  The subordinated notes were sold to accredited investors
through the placement agent Dougherty Summit Securities LLC. The Company
received $3.0 million in cash, less $240,000 in commission.  Additionally, the
Company granted 150,000 warrants to Dougherty Summit Securities LLC.  The
Company relied on an exemption from registration under Section 4(2) of the
Securities Act of 1933, as amended. Noteholders also received warrants to
purchase 1.5 million shares of common stock exercisable at $1.00 per share.  The
warrants are exercisable for five years.

  The sale and issuance of the securities described above were deemed to be
exempt from registration under the Securities Act in reliance on Section 4(2) of
the Securities act or Regulation D promulgated thereunder as transactions by an
issuer not involving a public offering, where the purchasers represented their
intention to acquire securities for investment purposes only and not with a view
to or for sale in connection with any distribution thereof, and received or had
access to adequate information about the Company.

                           FIELDWORKS, INCORPORATED

                     RESOLUTION ESTABLISHING THE SERIES,
                   SETTING FORTH THE DESIGNATION AND FIXING
                    THE RELATIVE RIGHTS AND PREFERENCES OF
               SERIES B CONVERTIBLE PARTICIPATING PREFERRED STOCK

     Pursuant to the powers expressly granted to the Board of Directors of
Fieldworks, Incorporated, a Minnesota corporation (the "Company"), by the
provisions of the Articles of Incorporation of the Company and Chapter 302A of
the Minnesota Business Corporation Act, the Board of Directors of the Company
duly established by written action of the Board of Directors a series of shares
consisting of 4,250,000 shares, with the designation of the series and the
relative rights and preferences of the series as follows:

     1.   Designation.  The designation of the series of shares is Series B
          -----------
Convertible Participating Preferred Stock (the "Series B Shares") and the number
of shares of such series is 4,250,000.

     2.   Dividends.  Dividends shall be payable on the Series B Shares out of
          ---------
funds legally available for the declaration of dividends only if and when
declared by the Board of Directors. In no event shall any dividend be paid or
declared, nor shall any distribution be made, on the Common Stock, unless the
holders of the Series B Shares shall have consented thereto and shall
participate in such dividend on a pro rata basis with the holders of Common
Stock, counting the Series B Shares on an as-if-converted basis.

     3.   Liquidation Preference. In the event of any liquidation, the holders
          ----------------------
of the Series B Shares then outstanding shall be entitled to receive out of the
assets of the Company, prior and in preference to any distribution of any of the
assets or surplus funds of the Company to the holders of the Common Stock or any
other class of shares of preferred stock of the Company ranking junior to the
Series B Shares with respect to payments upon Liquidation (such preferred stock
hereinafter called "Junior Liquidation Stock"), and junior to any such
distribution to the holders of any class of shares of the Company ranking senior
to the Series B Shares in such respect, an amount equal to $1.00 per share plus
any accrued and unpaid dividends thereon for each Series B Share (the "preferred
amount"). Following any distribution of assets or surplus funds of the Company
to the holders of any outstanding series of Junior Liquidation Stock, the
remainder of any such assets or, surplus funds shall be distributed to the
holders of the Common Stock until each

                                      -1-
<PAGE>

holder shall have received an amount per share equal to the preferred amount.
Thereafter, any remaining assets or funds shall be distributed pro rata to the
holders of the Common Stock and the holders of the Series B Preferred Stock,
counting Series B Shares on an as-if-converted basis. If upon the occurrence of
any Liquidation, the assets and funds of the Company available for the
distribution to its shareholders shall be insufficient to pay the holders of the
Series B Shares the full preferred amount to which they shall be entitled, the
holders of the Series B Shares shall share ratably in any distribution of such
assets and surplus funds in proportion to the Series B Shares held by them.

     4.   Voting Rights. Each holder of record of Series B Shares shall be
          -------------
entitled to notice of and to attend all meetings of the shareholders of the
Company and shall be entitled at each such meeting to a number of votes for each
Series B Share held equal to the number of shares of Common Stock into which
each share of Series B Shares is then convertible. Each holder of Common Stock
shall have one vote on all matters submitted to the shareholders for each share
of Common Stock standing in the name of such holder on the books of the Company.
Except as otherwise provided in this Section 4 and in Section 5, and except as
otherwise required by agreement or law, the holders of the Series B Shares and
the holders of Common Stock of the Company shall vote as a single class on all
matters submitted to the shareholders.

     5.   Special Voting Rights for Directors.
          -----------------------------------

          (a)  Other than as provided in paragraphs (b) and (c) below of this
Section 5, the number of directors of the Company shall be fixed at seven (7).

          (b)  So long as any Series B Shares remain outstanding, the holders of
the Series B Shares shall have the right, voting as a class, to elect three (3)
directors of the Company, and shall have the right under the circumstances
described in paragraph (c) below, voting as a class, to elect two (2) additional
directors of the Company (each such director, a "Series B Director").  Such
                                                 -----------------
holders shall have the exclusive right to (i) terminate any Series B Director
during his or her term of office, with or without cause; and (ii) to fill any
vacancy among the Series B Directors.

          (c)  The holders of the Series B Shares, acting by a majority vote,
shall have the right to compel the Company to take all necessary action to
increase the number of directors from seven (7) to nine (9), and the right to
appoint two (2) additional directors to fill the vacancies created by such
increase, upon the occurrence of any one or more of the following (each a
"Triggering Event"):

               (i)    the Company incurs operating losses in excess of
          $1,000,000 for the fourth quarter of 1999;

                                      -2-
<PAGE>

               (ii)   the Company incurs operating losses in excess of $100,000
          for the first quarter of 2000;

               (iii)  the Company incurs an operating loss in any amount for the
second quarter of 2000;

               (iv)   the Company achieves operating income of less than
$200,000 in the third quarter of 2000;

               (v)    the Company achieves operating income of less than
$400,000 in the fourth quarter of 2000;

               (vi)   the Company achieves operating income of less than
$600,000 in the first quarter of 2001;

               (vii)  the Company achieves operating income of less than
$800,000 in the second quarter of 2001; or

               (viii) the Company achieves operating income of less than
$1,000,000 in any quarter commencing with the third quarter of 2001.

          (d)  As used in this Section 5, "operating income" and "operating
losses" shall mean, for any period, the amount of operating income or losses for
such period, if any, determined in accordance with generally accepted accounting
principles applied in a manner consistent with the application of such
principles in periods prior to 1999, provided that the impact of any expenses
directly attributable to the Management Services Agreement, dated  November 20,
1999, between the Company and Glenmount, LLC and revenues or expenses directly
attributable to (a) any reversal of prior inventory, warranty or other reserves,
(b) any sale of assets (other than inventory in the ordinary course), and (c)
any business acquired by the Company after the date hereof through merger,
acquisition of securities, acquisition of assets or otherwise, in each case,
shall be excluded from the determination of operating income or operating losses
pursuant to this sentence.

          (e)  This right of the holders of the Series B Shares to name two
additional directors shall lapse, and the number of Company directors shall
reduce to seven, if, six months after the election of two additional Series B
directors, the holders of the Series B shares have not exercised the conversion
rights granted in Section 7 below.

                                      -3-
<PAGE>

     6.   Protective Provisions. The Company shall not take any of the following
          ---------------------
actions without the prior affirmative written consent of the holders of at least
two-thirds (2/3) of the Series B Shares:

          (a)  alter, change or amend (by merger or otherwise) any of the
     rights, preferences or privileges of the Series B Shares;

          (b)  other than as provided in Section 5(c) hereof, amend, restate,

     Incorporation or the Bylaws of the Company, including, without limitation,
     amending, restating, modifying or repealing (by merger or otherwise) (i)

     shares of any such class or series of securities the holders of which have
     the right to cast more than one vote per share, and/or have the right,
     voting as a class or series, to elect one or more members of the Board of
     Directors; (iii) create, authorize or issue any securities or shares of any
     such class or series of securities convertible into, or exercisable,

     7.   Conversion Rights.
          -----------------

          (a)  At Option of Holders.  Holders of Series B Shares may, at their
               --------------------
option, upon surrender of the certificates therefor, convert any or all of their
Series B Shares into fully paid and nonassessable shares of Common Stock at any
time. The right of holders of Series B Shares to convert their shares shall be
exercised by surrendering for such purpose to the Company or any transfer agent
for the Series B Shares, and at such other office or offices, if any, as the
Board of Directors may designate, certificates representing the Series B Shares
to be converted, duly endorsed in blank or accompanied by proper instruments of
transfer. Upon the surrender of certificates representing the Series B Shares to
be converted, the person converting such shares shall be deemed to be the holder
of record of the Common Stock (and such other securities and property as the
holders of Series B Shares may be entitled to upon the conversion thereof, as
hereinafter provided) issuable upon such conversion, and all rights with respect
to the Series B Shares surrendered shall forthwith terminate except the right to
receive the Common Stock or other securities, cash or other assets receivable
upon such conversion as herein provided.

          (b)  Conversion Rate/Conversion Price.  In addition to the adjustments
               --------------------------------
required by Section 7(e) and 7(f), the conversion of Series B Shares into Common
Stock shall be governed by the following: Series B Shares shall be convertible
into that number of fully paid and nonassessable shares of Common Stock
(calculated as to each conversion to the nearest 1/100th of a share) as shall be
determined by multiplying the "Conversion Rate," determined as hereinafter
provided, in effect at the time of conversion by the product of (i) the number
of shares of Series B Shares to be converted and (ii) the "Initial Conversion
Price" applicable to the shares of Series B Shares being converted (as
hereinafter defined) and dividing the product of such multiplication by the
"Conversion Price" applicable to the Series B Shares being converted, determined
as hereinafter provided, in effect at the time of conversion and making any
adjustments required by Section 7(e) hereof. The conversion rate shall initially
be one and shall be adjusted from time to time as provided in Section 7(e) (such
conversion rate, as so adjusted from time to time, being referred to herein as
the "Conversion Rate"). The "Initial Conversion Price" for the Series B Shares
shall be the price per Series B Share paid to the company upon the issuance
thereof. The conversion price for Series B Shares shall initially be equal to
the Initial Conversion Price and shall be adjusted from time to time as provided
in Section 7(f) (the conversion price for Series B Shares, as so adjusted from
time to time, being herein referred to as the "Conversion Price" applicable to
such Series B Shares).

          (c)  Reservation of Shares.  A number of shares of authorized but
               ---------------------
unissued Common Stock of the Company sufficient to provide for the conversion of
all of the Series B Shares outstanding upon the basis herein provided
("Conversion Common Stock") shall at all times be reserved by the Company, free
from preemptive rights, for such conversion. If the Company

                                      -7-
<PAGE>

shall issue any securities or make any change in its capital structure that
would change the number of shares of Common Stock into which each Series B Share
shall be convertible as herein provided, the Company shall at the same time also
make proper provision so that thereafter there shall be a sufficient number of
additional shares of capital stock authorized and reserved, free from preemptive
rights, for conversion of the outstanding Series B Shares on the new basis. The
Company shall comply with all securities laws regulating the offer and delivery
of shares of Common Stock upon conversion of Series B Shares and shall list such
shares on any national securities exchange on which the Common Stock is listed
or have such shares admitted for quotation on the Nasdaq National or Small Cap
Market if the Common Stock is admitted for quotation thereon.

          (d)  Fractional Shares.  No fractional shares of Common Stock shall be
               -----------------
issued upon the conversion of Series B Shares but, in lieu of any fraction of a
share of Common Stock that would otherwise be issuable in respect of the
aggregate number of such shares surrendered for conversion at one time by the
same holder, the Company shall pay in cash an amount equal to the product of (a)
the "Closing Price" (as defined in the next sentence) of a share of Common Stock
on the last trading day before the relevant conversion date and (b) such
fraction of a share. The "Closing Price" for each day shall be the last reported
sale price regular way or, in case no sale takes place on such day, the average
of the closing bid and asked prices regular way on such day, in either case as
reported on the New York Stock Exchange Composite Tape, or, if the Common Stock
is not listed or admitted to trading on such Exchange, on the principal national
securities exchange on which the Common Stock is listed or admitted to trading,
or, if the Common Stock is not listed or admitted to trading on any national
securities exchange, on the Nasdaq National or Small Cap Market, or, if the
Common Stock is not admitted for quotation on the Nasdaq National or Small Cap
Market, the average of the high bid and low asked prices on such day as recorded
by the National Association of Securities Dealers, Inc. through Nasdaq, or, if
the National Association of Securities Dealers, Inc. through Nasdaq shall not
have reported any bid and asked prices for the Common Stock on such day, the
average of the bid and asked prices for such day as furnished by any New York
Stock Exchange member firm selected from time to time by the Company for such
purpose, or, if no such bid and asked prices can be obtained from any such firm,
the fair market value of one share of the Common Stock on such day as determined
in good faith by the Board of Directors of the Company.

          (e)  Conversion Rate Adjustments.  Subject to Section 7(f) hereof, if
               ---------------------------
the Company shall (A) subdivide its outstanding Common Stock into a greater
number of shares, (B) combine the shares of its outstanding Common Stock into a
smaller number of shares or (C) declare a dividend upon its shares of Common
Stock payable in shares of Common Stock, then in each such case the Conversion
Rate in effect immediately prior thereto shall be proportionately adjusted so
that the holder of any shares of any Series B Shares thereafter

                                      -8-
<PAGE>

surrendered for conversion shall be entitled to receive, to the extent permitted
by applicable law, the number and kind of shares of capital stock of the Company
that such holder would have owned or have been entitled to receive after the
happening of such event had such Series B Shares been converted immediately
prior to the record date for such event (or if no record date is established in
connection with such event, the effective date for such action). An adjustment
pursuant to this Section 7(e) shall become effective immediately after the
record date in the case of a stock dividend or distribution, or immediately
after the effective date in the case of a subdivision, combination or
reclassification.

          (f)  Conversion Price Adjustments. With respect to Series B Shares, if
               ----------------------------
and whenever the Company shall issue or sell any shares of its Common Stock or
any securities convertible into or exercisable or exchangeable for shares of
Common Stock ("Convertible Securities") for a consideration per share (in the
case of the sale of any Convertible Securities, the amount, if any, payable for
such Convertible Security and upon the exercise or conversion thereof (and/or
upon the exercise or conversion of the securities receivable upon such exercise
or conversion) for each share of Common Stock receivable thereby shall be
included in determining such consideration per share) less than the Conversion
Price applicable to the Series B Shares, in effect immediately prior to the time
of such issuance or sale, then, forthwith upon such issuance or sale, such
higher Conversion Price(s) for the Series B Shares shall be reduced to a price
(calculated to the nearest tenth of a cent) determined by dividing (x) an amount
equal to the sum of (A) the number of shares of Common Stock outstanding
immediately prior to such issuance or sale multiplied by such higher Conversion
Price plus (B) the aggregate consideration, if any, received or receivable by
      ----
the Company for the shares of Common Stock issued or issuable upon the exercise
of any issued Convertible Security (and/or upon the exercise or conversion of
the security receivable upon such exercise or conversion), by (y) an amount
equal to the sum of (A) the number of shares of Common Stock outstanding
immediately prior to such issuance or sale plus (B) the number of shares of
                                           ----
Common Stock thus issued or sold or receivable upon the exercise or conversion
of the Convertible Securities (or the securities receivable upon the exercise or
conversion of such Securities). If any Convertible Securities taken into account
in any such adjustment of a Conversion Price subsequently expire without
exercise, such Conversion Price shall be recomputed to eliminate the effect of
such expired Convertible Securities. However, no adjustment pursuant to this
Section 7(f) shall be required upon the issuance of shares of Common Stock upon
conversion of any shares of preferred stock, including the Series B Shares,
outstanding prior to such issuance or sale or upon the exercise of options
available under the 1996 Directors Stock Option Plan or the 1999 Long-term
Incentive Plan of the Company as in effect prior to November 1, 1999.

          (g)  Consolidations, Mergers, Sales of Assets, Reclassifications and
               ---------------------------------------------------------------
Certain Dividends.  In case of any (A) consolidation or merger of the Company
- -----------------
with any other company

                                      -9-
<PAGE>

(other than the merger of a subsidiary of the Company into the Company in a
transaction in which the Company is the surviving corporation and the
outstanding shares of capital stock of the Company are not exchanged for or
converted into any other securities, cash or other property), (B) sale or
transfer of all or substantially all of the assets of the Company for cash,
securities or other property, (C) any share exchange pursuant to which all of
the outstanding shares of Common Stock are converted into other securities or
property, or (D) issuance of any shares of the Company's capital stock in
connection with a reclassification of the Common Stock, the Company shall, prior
to or at the time of such transaction, make appropriate provision or cause
appropriate provision to be made so that the holders of each Series B Share then
outstanding shall have the right thereafter to receive the kind and amount of
shares of stock and other securities and property receivable upon such
consolidation, merger, sale, transfer, share exchange or reclassification by a
holder of the number of shares of Common Stock into which such Series B Shares
could have been converted immediately prior to the effective date of such
consolidation, merger, sale, transfer, share exchange or reclassification.  If
in connection with any such consolidation, merger, sale, transfer, share
exchange or reclassification, each holder Common Stock is entitled to elect to
receive either securities, cash or other assets upon completion of such
transaction, the Company shall provide or cause to be provided to each holder of
Series B Shares the right to elect the securities, cash or other assets into
which the Series B Shares held by such holder shall be convertible after
completion of any such transaction on the same terms and subject to the same
conditions applicable to holders of the Common Stock (including, without
limitation, notice of the right to elect, limitations on the period in which
such election shall be made and the effect of failing to exercise the election).

          (h)  Rounding. All calculations hereunder, unless otherwise specified,
               --------
shall be made to the nearest cent or to the nearest 1/100th of a share, as the
case may be.

          (i)  Notices.  Whenever the Conversion Rate or a Conversion Price is
               -------
adjusted as herein provided, the Company shall give prompt notice by mail to the
holders of the outstanding Series B Shares of such adjustment, which notice
shall set forth the adjustment and the new Conversion Rate or Conversion Price.
Notwithstanding the foregoing, failure by the Company to give such notice or a
defect in such notice shall not affect the binding nature of such corporate
action of the Company.

          (j)  Common Stock Defined.  As used herein, the term "Common Stock"
               --------------------
shall mean and include the presently authorized Common Stock of the Company and
shall also include any capital stock of any class of the Company (other than the
Series B Shares) hereafter authorized which shall have the right to vote on all
matters submitted to the shareholders of the Company and shall not be limited to
a fixed sum or percentage in respect of the rights of the holders thereof to
participate in dividends or in the distribution of assets upon the occurrence of
any Liquidation Event of the Company.

     8.   Preemptive Rights.  If Company offers to sell its common stock,
          -----------------
securities convertible into common stock, or any other debt (excluding debt
securities issued to banks or other financial institutions) or equity securities
other than the issuance of options or shares to employees, directors and
consultants which have been approved by the Series B Directors (the "Additional
Securities") it will first offer to the holders of the Series B Shares, or, if
applicable, Conversion Common Stock the right to purchase a portion of the
Additional Securities such that such holders' aggregate percentage ownership of
the Company on a fully diluted basis ("Purchasers' Percentage") will be
unchanged. The offer shall set forth the number of shares to be sold, the price,
and material terms and conditions.

The right of the holders to purchase in the aggregate Additional Securities up
to but not more than the Purchaser's Percentage may be exercised as follows:

          (a)  the Company shall provide each holder with written notice of the
number of securities to be issued and the cash price therefor;

          (b)  each holder shall have the right to purchase that percentage of
such securities equal to the ratio that the number of shares of Conversion
Common Stock held by such holder bears to the total number of shares of
Conversion Common Stock held by all holders;

          (c)  second, if not all holders elect to purchase their pro rata
share, then as to the excess of the amount of Purchaser's Percentage over the
shares taken by holders electing to purchase their pro rata part (such excess to
be referred to as the "Unsubscribed Shares"), the holders who do so elect shall
be offered the right to acquire pro rata among themselves based on their
holdings of Conversion Common Stock; and

          (d)  if after such offer, any of the Unsubscribed Shares remain
unsold, as to such unsold Unsubscribed Shares, as the holders who agreed to
purchase their pro rata part of the Unsubscribed Shares may agree, all within
thirty (30) days of notice by the Company of such proposed issuance.

          The Company may, within thirty (30) days, sell the remaining
securities not to be purchased by the holders to third parties on the terms and
conditions set forth in the offer delivered to holders, and the holders shall be
required to deliver the consideration to Company for the securities being
purchased by the holders at the same time such third parties are required to
deliver their consideration to Company.

                                     -11-
<PAGE>

          Notwithstanding anything in this Section 8 to the contrary, the
holders' rights under this Section 8 shall not apply to (i) the securities of
the Company outstanding immediately prior to the issuance of the initial Series
B Shares; (ii) shares of common stock issued in connection with any stock split,
stock dividends or recapitalization of Company or upon conversion of the Series
B Shares; (iv) any borrowings, direct or indirect from financial institutions by
the Company, whether or not presently authorized, evidenced by any type of debt
instrument with no equity features; (v) securities issued pursuant to an
effective registration statement filed with the SEC in connection with a
registered public offering; (vi) equity securities issued to a financial
institution in connection with any lease financing or debt financing of the
Company approved by a two-thirds (2/3) vote of the Board of Directors; or (vii)
any transaction in which all directors of the Company elect for this Section 8
not to apply.

issuable upon exercise of this Warrant. The value of the shares so surrendered
shall be the closing price of the Company's common stock on the date of Holder's
notice of exercise.

                                      -2-
<PAGE>

     3.   Shares.  All shares that may be issued upon the exercise of the rights
          ------
represented by this Warrant shall, upon issuance, be duly authorized and issued,
fully paid and nonassessable shares.  During the period within which the rights
represented by this Warrant may be exercised, the Company shall at all times
have authorized and reserved for the purpose of issue or transfer upon exercise
of the subscription rights evidenced by this Warrant a sufficient number of
shares of its common stock to provide for the exercise of the rights represented
by this Warrant.

     4.   Adjustment.  The Warrant Exercise Price shall be subject to adjustment
          ----------
from time to time as hereinafter provided in this Section 4:

          (a)  If the Company at any time divides the outstanding shares of its
     common stock into a greater number of shares (whether pursuant to a stock
     split, stock dividend or otherwise), and conversely, if the outstanding
     shares of its common stock are combined into a smaller number of shares,
     the Warrant Exercise Price in effect immediately prior to such division or
     combination shall be proportionately adjusted to reflect the reduction or
     increase in the value of each such common share.

          (b)  If any stock dividend, capital reorganization or reclassification
     of the capital stock of the Company, or consolidation or merger of the
     Company with another corporation, or the sale of all or substantially all
     of its assets to another corporation shall be effected in such a way that
     holders of the Company's common stock shall be entitled to receive stock,
     securities or assets with respect to or in exchange for such common stock,
     then, as a condition of such stock dividend, reorganization,
     reclassification, consolidation, merger or sale, Holder shall have the
     right to purchase and receive upon the basis and upon the terms and
     conditions specified in this Warrant and in lieu of the shares of the
     common stock of the Company immediately theretofore purchasable and
     receivable upon the exercise of the rights represented hereby, such shares
     of stock, other securities or assets as would have been issued or delivered
     to the Holder if Holder had exercised this Warrant and had received such
     shares of common stock immediately prior to such stock dividend,
     reorganization, reclassification, consolidation, merger or sale. The
     Company shall not effect any such consolidation, merger or sale unless
     prior to the consummation thereof the successor corporation (if other than
     the Company) resulting from such consolidation or merger or the corporation
     purchasing such assets shall assume by written instrument executed and
     mailed to Holder at the last address of Holder appearing on the books of
     the Company the obligation to deliver to Holder such shares of stock,
     securities or assets as, in accordance with the foregoing provisions,
     Holder may be entitled to purchase.

          (c)  If and whenever the Company shall (1) issue or sell any shares of
     its common stock for a per-share consideration less than the Warrant
     Exercise Price in effect

                                      -3-
<PAGE>

     immediately prior to the time of such issuance or sale, (2) issue or sell
     any warrants, options or other rights to acquire shares of its common stock
     at a purchase price less than the Warrant Exercise Price in effect
     immediately prior to the time of such issuance or sale, or (3) issue or
     sell any other securities that are convertible into shares of its common
     stock for a purchase or exchange price less than the Warrant Exercise Price
     in effect immediately prior to the time of such issuance or sale (except
     for the issuance or sale of shares of the Company's common stock pursuant
     to stock option plans, stock purchase plans or other employee stock
     incentive programs adopted by the Company's Board of Directors, or pursuant
     to business acquisition or lease financing transactions), then, upon such
     issuance or sale, the Warrant Exercise Price shall be reduced to the price
     (calculated to the nearest cent) determined by dividing (A) an amount equal
     to the sum of (1) the number of shares of the Company's common stock
     outstanding immediately prior to such issue or sale multiplied by the then
     existing Warrant Exercise Price and (2) the consideration, if any, received
     by the Company upon such issue or sale plus the consideration to be
     received by the Company upon the exercise of such stock purchase rights by
     (B) an amount equal to the sum of (1) the number of shares of its common
     stock outstanding immediately prior to such issue or sale and (2) the
     number of its shares of common stock thus issued or sold or issuable or
     saleable upon the exercise of such purchase rights or the conversion of
     such convertible securities; provided, however, that in the event that any
     such purchase right expires or is terminated prior to the exercise of this
     Warrant, the Warrant Exercise Price shall be recalculated by deleting such
     purchase right and provided further that if an adjustment is made to the
     Warrant Exercise Price as a result of the issuance or sale of any such
     purchase rights or convertible securities, no further adjustment shall be
     made to the Warrant Exercise Price at the time such purchase rights are
     exercised or convertible securities are converted.

          (d)  Upon any adjustment of the Warrant Exercise Price, Holder shall
     thereafter be entitled to purchase, at the Warrant Exercise Price resulting
     from such adjustment, the number of shares obtained by multiplying the
     Warrant Exercise Price in effect immediately prior to such adjustment by
     the number of shares purchasable pursuant hereto immediately prior to such
     adjustment and dividing the product thereof by the Warrant Exercise Price
     resulting from such adjustment.

          (e)  Upon any adjustment of the warrant exercise price, the Company
     shall give written notice thereof to Holder, stating the Warrant Exercise
     Price resulting from such adjustment and the increase or decrease, if any,
     in the number of shares purchasable at such price upon the exercise of this
     Warrant, setting forth in reasonable detail the method of calculation and
     the facts upon which such calculation is based.

                                      -4-
<PAGE>

     5.   No Rights as Shareholder. This Warrant shall not entitle Holder to any
          ------------------------
voting rights or other rights as a shareholder of the Company.

     6.   Registration Rights.  Holder shall be entitled to certain demand
          -------------------
registration rights and also entitled to participate in any registered offering
of shares of the Company's common stock.  Holder's participation in any such
offering shall be in accordance with the procedures, and subject to the
limitations, set forth on Exhibit A to this Warrant.

     7.   Transfer.  This Warrant and all rights hereunder are transferable, in
          --------
whole or in part, at the principal office of the Company by the holder hereof in
person or by duly authorized attorney, upon surrender of this Warrant properly
endorsed to any person or entity who represents in writing that such person or
entity is acquiring the Warrant for investment and without any view to the sale
or other distribution thereof.  Each holder of this Warrant, by taking or
holding the same, consents and agrees that the bearer of this Warrant, when
endorsed, may be treated by the Company and all other persons dealing with this
Warrant as the absolute owner hereof for any purpose and as the person entitled
to exercise the rights represented by this Warrant, or to the transfer hereof on
the books of the Company, any notice to the contrary notwithstanding; but until
such transfer on such books, the Company may treat the registered owner hereof
as the owner for all purposes.

     8.   Notices.  All demands and notices to be given hereunder shall be
          -------
delivered or sent by first class mail, postage prepaid; in the case of the
Company, addressed to its corporate headquarters, Attention: Chief Financial
Officer, 7631 Anagram Drive, Eden Prairie, MN 55344, until a new address shall
have been substituted by like notice; and in the case of Holder, addressed to

          --------------------

          (a)  Timing Of Demand Registrations; Required Threshold.
               --------------------------------------------------

          At any time after the first anniversary of this Agreement, any
Eligible Holder owning at least one million five hundred thousand (1,500,000)
Common Stock Equivalents (as such number may be equitably adjusted from time to
time to reflect any stock split, stock dividend, recapitalization,
reclassification, consolidation or the like) may request (such Person, the
"Initiating Holder") that the Company file a Registration Statement under the
Securities Act on an appropriate form with respect to at least fifty percent
(50%) of the Registrable Securities owned by such Initiating Holder (which form
shall be available for the sale of the Registrable Securities in accordance with
the intended method or methods of distribution thereof and shall include all
financial statements required by the SEC to be filed herewith) covering the
shares of Registrable Securities that are the subject of such request and the
Company shall file such a Registration Statement.

                                      A-2
<PAGE>

          (b)  Number of Demand Registrations.
               ------------------------------

          The Company shall be obligated to prepare, file and cause to become
effective pursuant to this Section 2 no more than two (2) Registration
Statements in the aggregate pursuant to Section 2(a) above for the Eligible
Holders; provided, however, that a Registration Statement shall not be counted
as one of the two (2) Demand Registrations hereunder unless it becomes effective
and is maintained effective in accordance with the requirements specified in
Section 6(a); provided, further, that if there is an underwriter's cutback
pursuant to Section 2(e) with respect to the second request for registration
initiated by an Eligible Holder, such requested registration shall not be deemed
to be a requested registration for purposes of the limitation to two (2) Demand
Registrations pursuant to this Section 2(b).

          (c)  Deferral by Company.
               -------------------

          Notwithstanding anything in this Section 2 to the contrary, the
Company shall not be obligated to prepare, file and cause to become effective
pursuant to this Section 2 a Registration Statement if within five (5) days of
receipt of a request for a Demand Registration the Company furnishes to the
Initiating Holder a certificate signed by the Chief Executive Officer of the
Company that, in the good faith judgment of the Board of Directors, it would be
detrimental in any material respect to the Company and its shareholders for the
Company to comply with the Demand Registration, and it is therefore essential to
defer the filing of the Registration Statement relating thereto.  Any such
deferral shall be for a period of not more than six (6) months after the
Company's receipt of the Initiating Holder's written request for registration
pursuant to this Section 2; provided, however, that the Company may not exercise
this right more than once with respect to a Demand Registration and that any
requested registration deferred, and not ultimately effected, by the Company
pursuant to the provisions of this Section 2(c) shall thereafter not be deemed
to be a requested registration for purposes of the limitation to two (2) Demand
Registrations pursuant to Section 2(a) above.

          (d)  Participation.
               -------------

          The Company shall promptly give written notice to all other Eligible
Holders upon receipt of a request for a Demand Registration pursuant to Section
2(a) above.  Such other Eligible Holders may, by written notice to the Company
and the Initiating Holder, within thirty (30) business days of the Company's
notice, elect to join in a request for a Demand Registration pursuant to Section
2(a) above, with respect to any number of shares of Registrable Securities owned
by such Eligible Holder.  The Registrable Securities of the other Eligible
Holders being offered in such Demand Registration shall be treated pari passu
with the Registrable Securities being offered by the Initiating Holder for all
purposes including "underwriter's cutbacks" under subsection (e) of this Section
and any such request by an Eligible Holder shall not be treated as either a
request by such Eligible Holder for a Piggyback Registration under Section 3 or
as a request by such Eligible

                                      A-3
<PAGE>

Holder for a Demand Registration under this Section 2.  The Company shall
include in such Demand Registration such shares of Registrable Securities for
which it has received written requests to register such shares within thirty
(30) days after such written notice has been given, provided that all the
Registrable Securities for which the Initiating Holder and the other Eligible
Holders have requested registration shall be covered by such registration
statement before any other securities are included.

          In addition, the Company shall promptly give written notice to all
eligible Holders upon receipt of a request for a demand registration by any
Person (such Person, the "Initiating Person") pursuant to any other registration
rights agreement with the Company (whether such other registration rights
agreement is entered into before or after the date hereof).  Each Eligible
Holder may, by written notice to the Company, within thirty (30) business days
of the Company's notice, elect to request a Demand Registration pursuant to
Section 2(a) above, with respect to any shares of Registrable Securities owned
by such Eligible Holder.  The Registrable Securities of the Eligible Holders
being offered in such Demand Registration shall be treated pari passu with the
registrable securities being offered by the Initiating Person for all purposes
including "underwriter's cutbacks" and any such request by an Eligible Holder
shall not be treated as either a request by such Eligible Holder for a Piggyback
Registration under Section 3 or as a request by such Eligible Holder for a
Demand Registration under this Section 2.  Further, the selection of the
managing underwriter and the underwriters for the demand registration requested
by the Initiating Person shall be subject to the approval of a majority in
interest of the Eligible Holders participating in any underwritten offering.
The Company shall include in such demand registration such shares of Registrable
Securities for which it has received written requests to register such shares
within thirty (30) days after such written notice has been given, provided that
all the Registrable Securities for which the Initiating Person and the Eligible
Holders have requested registration shall be covered by such registration
statement before any other securities are included.

          (e)  Underwriter's Cutback.
               ---------------------

          If the public offering of Registrable Securities is to be underwritten
and, in the good faith judgment of the managing underwriter, the inclusion of
all the Registrable Securities requested to be registered hereunder would
interfere with the successful marketing of such shares of Registrable
Securities, the number of shares of Registrable Securities to be included shall
be reduced and the number of shares to be included in the underwriting or
registration shall be allocated first among the Eligible Holders pro rata upon
the basis of the number of shares of Registrable Securities sought to be offered
by the Eligible Holders pursuant to such Demand Registration and any remainder
shall be allocated among the Company and the other persons entitled to
incidental registrations pro rata upon the basis of the number of shares of
Registrable Securities sought to be registered thereby.  If a person who has
requested inclusion in such Demand Registration does not agree to the terms of
any such underwriting, such person shall be excluded therefrom by written notice
from the Company, the underwriter or the Initiating Holder,

                                     A-4
<PAGE>

and the securities owned by such person(s) shall be withdrawn from registration
(the "Withdrawn Securities").

          If there are any Withdrawn Securities as a result of an Underwriter's
Cutback, then the Company shall offer to those persons who have retained rights
to include securities in the Demand Registration the right to include additional
securities in the registration in an aggregate amount equal to the number of
Withdrawn Securities that would have been included in the Demand Registration
after giving effect to the Underwriter's Cutback had such securities not been
withdrawn, with such shares to be allocated among such persons in accordance
with the allocation of rights set forth in this paragraph (e).

          (f)  Managing Underwriter.
               --------------------

          The managing underwriter or underwriters of any Underwritten Offering
covered by a Demand Registration shall be selected by a majority in interest of
the Eligible Holders participating in such Underwritten Offering and shall be
reasonably acceptable to the Company. The right of any other Holders joining in
a request for registration as provided in Section 2(d) above to registration
pursuant to this Section 2 shall be conditioned upon such Holder's participation
in such underwriting and the inclusion of such Holder's Registrable Securities
in the underwriting on the same terms as those of the Initiating Holder (unless
otherwise mutually agreed by a majority in interest of the Eligible Holders
participating in such registration and such Holder with respect to such
participation and inclusion).

     3.   Piggyback Registrations
          -----------------------

          (a)  Participation.
               -------------

          Each time the Company decides to file a Registration Statement under
the Securities Act (other than registrations on Forms S-4 or S-8 or any
successor form thereto, and other than a Demand Registration or a demand
registration by an Initiating Person) covering the offer and sale by it or any
of its security holders of any of its securities for money, the Company shall
give written notice thereof to all Eligible Holders.  The Company shall include
in such Registration Statement such shares of Registrable Securities for which
it has received a written request from any Eligible Holder to register such
shares within twenty (20) days after such written notice has been given.  If the
Registration Statement is to cover an Underwritten Offering, such Registrable
Securities shall be included in the underwriting on the same terms and
conditions as the securities otherwise being sold through the underwriters.

                                      A-5
<PAGE>

          (b)  Underwriter's Cutback.
               ---------------------

          Subject to the requirements of Section 12 hereof, if in the good faith
judgment of the managing underwriter of such offering the inclusion of all of
the shares of Registrable Securities and any other Common Stock requested to be
registered would interfere with the successful marketing of such shares, then
the number of shares of Registrable Securities and other Common Stock to be
included in the offering shall be reduced, with the participation in such
offering to be in the following order of priority:  (1) first, the shares of
Common Stock which the Company proposes to sell for its own account, (2) second,
the shares of Registrable Securities of all Eligible Holders requested to be
included, and (3) third, any other shares of Common Stock requested to be
included.  Any necessary allocation among the Holders of shares within each of
the foregoing groups shall be pro rata among such Holders requesting such
registration based upon the number of shares of Common Stock and Registrable
Securities owned by such Holders.

          (c)  Company Control.
               ---------------

          The Company may decline to file a Registration Statement after giving
notice to Eligible Holders pursuant to Section 3(a) above, or withdraw a
Registration Statement after filing and after such notice, but prior to the
effectiveness thereof; provided that the Company shall promptly notify each
Eligible Holder in writing of any such action and provided further that the
Company shall bear all expenses incurred by each Eligible Holder or otherwise in
connection with such withdrawn Registration Statement.

     4.   Registration on Form S-3
          ------------------------

          (a)  Right to Request Registrations on Form S-3.
               ------------------------------------------

          After the Company has qualified for the use of Form S-3, in addition
to the rights contained in the foregoing provisions of this Agreement, the
Eligible Holders shall have the right to request registrations on Form S-3 or
any comparable or successor form.  Each such request shall be in writing and
shall state the anticipated number of shares of Registrable Securities to be
disposed of and the anticipated gross proceeds of such shares, and the intended
methods of disposition of such shares by such Eligible Holder or Eligible
Holders, including whether such resales are to be made on a delayed or
continuous basis pursuant to Rule 415.  The Company shall not be obligated to
effect any registration pursuant to this Section 4 if (i) the Eligible Holders
propose to sell Registrable Securities representing less than fifteen percent
(15% ) of the shares of the Registrable Securities then held by all Eligible
Holders or (ii) the circumstances described in Section 2(c) shall apply (but
subject to the limitations set forth therein).

          (a)  By Holders of Registrable Securities.
               ------------------------------------

          Upon the written request of the managing underwriter of any
Underwritten Offering of the Company's securities, a Holder of Registrable
Securities shall not sell or otherwise dispose of any Registrable Securities
(other than those included in such registration) without the prior written
consent of such managing underwriter for a period (not to exceed thirty (30)
days before the effective date and one hundred twenty (120) days thereafter)
that such managing underwriter reasonably determines is necessary in order to
effect the Underwritten Offering; provided that each of the officers and
directors of the Company, and each Holder of more than one percent (1%) of the
Common Stock of the Company, shall have entered into substantially similar
holdback agreements with such managing underwriter covering at least the same
period.

          (b)  By the Company and Others.

          any of its equity securities during the 30-day period prior to, and
          during the 120-day period after, the effective date of each
          Underwritten Offering made pursuant to a Demand Registration or a
          Piggyback Registration, if so requested in writing by the managing
          underwriter (except as part of such Underwritten Offering, pursuant to
          registrations on Forms S-4 or S-8 or any successor forms thereto), and

               (2)  not to issue any Equity Securities other than for sale in a
          registered public offering unless each of the Persons to which such
          securities are issued has entered a written agreement binding on its
          transferees not to effect any public sale or distribution of such
          securities during such 130-day period, including without limitation a
          sale pursuant to Rule 144 under the Securities Act (except as part of
          such Underwritten Registration, if and to the extent permitted
          hereunder).

          Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose, and

               (6)  of the existence of any fact which results in the

                            FIELDWORKS, INCORPORATED

                      RESOLUTION ESTABLISHING THE SERIES,
                    SETTING FORTH THE DESIGNATION AND FIXING
                     THE RELATIVE RIGHTS AND PREFERENCES OF
               SERIES C CONVERTIBLE PARTICIPATING PREFERRED STOCK

     Pursuant to the powers expressly granted to the Board of Directors of
Fieldworks, Incorporated, a Minnesota corporation (the "Company"), by the
provisions of the Articles of Incorporation of the Company and Chapter 302A of
the Minnesota Business Corporation Act, the Board of Directors of the Company
duly established by written action of the Board of Directors a series of shares
consisting of 500,000 shares, with the designation of the series and the
relative rights and preferences of the series as follows:

     1.   Designation.  The designation of the series of shares is Series C
          -----------
Convertible Participating Preferred Stock (the "Series C Shares") and the number
of shares of such series is 500,000.

     2.   Dividends.  Dividends shall be payable on the Series C Shares out of
          ---------
funds legally available for the declaration of dividends only if and when
declared by the Board of Directors. In no event shall any dividend be paid or
declared, nor shall any distribution be made, on the Common Stock, unless the
holders of the Series C Shares shall have consented thereto and shall
participate in such dividend on a pro rata basis with the holders of Common
Stock, counting the Series C Shares on an as-if-converted basis.

     3.   Liquidation Preference. In the event of any liquidation, the holders
          ----------------------
of the Series C Shares then outstanding shall be entitled to receive out of the
assets of the Company, after distribution of all amounts due the holders of the
Company's Series B Convertible Participating Preferred Stock ("Series B
Preferred Stock"), but prior and in preference to any distribution of any of the
assets or surplus funds of the Company to the holders of the Common Stock or any
other class of shares of preferred stock of the Company ranking junior to the
Series C Shares with respect to payments upon Liquidation (such preferred stock
hereinafter called "Junior Liquidation Stock"), and junior to any such
distribution to the holders of any class of shares of the Company ranking senior
to the Series C Shares in such respect, an amount equal to $2.00 per share plus
any accrued and unpaid dividends thereon for each Series C Share (the "preferred
amount"). Following any distribution of assets or surplus funds of the Company
to the holders of any outstanding series of Junior Liquidation Stock, the
remainder of any such assets or, surplus funds shall be


                                      -2-
<PAGE>

distributed to the holders of the Common Stock and any other series of preferred
stock entitled to participate in distributions of assets or surplus funds upon
liquidation until each holder shall have received an amount per share equal to
the preferred amount. Thereafter, any remaining assets or funds shall be
distributed pro rata to the holders of the Common Stock, the holders of any
other series of preferred stock having a right to participate, and the holders
of the Series C Preferred Stock, counting Series C Shares on an as-if-converted
basis. If upon the occurrence of any Liquidation, the assets and funds of the
Company available for the distribution to its shareholders shall be insufficient
to pay the holders of the Series C Shares the full preferred amount to which
they shall be entitled, the holders of the Series C Shares shall share ratably
in any distribution of such assets and surplus funds available to the Series C
Shares in proportion to the Series C Shares held by them.

     4.   Voting Rights. Each holder of record of Series C Shares shall be
          -------------
entitled to notice of and to attend all meetings of the shareholders of the
Company and shall be entitled at each such meeting to a number of votes for each
Series C Share held equal to the number of shares of Common Stock into which
each share of Series C Shares is then convertible. Each holder of Common Stock
shall have one vote on all matters submitted to the shareholders for each share
of Common Stock standing in the name of such holder on the books of the Company.
Except as otherwise provided in this Section 4, and except as otherwise required
by agreement or law, the holders of the Series C Shares and the holders of
Common Stock of the Company shall vote as a single class on all matters
submitted to the shareholders.

     5.   Protective Provisions.  The Company shall not take any of the
          ---------------------
following actions without the prior affirmative written consent of the holders
of at least two-thirds (2/3) of the Series C Shares:

          (a) alter, change or amend (by merger or otherwise) any of the rights,
     preferences or privileges of the Series C Shares;

          (b) other than as provided in Section 5(c) of the Certificate of
     Designation of Rights, Preferences and Limitations of the Company's Series
     B Preferred Stock, amend, restate, alter, modify or repeal (by merger or
     otherwise) the Articles of Incorporation or the Bylaws of the Company,
     including, without limitation, amending, restating, modifying or repealing
     (by merger or otherwise) (i) any certificate of designation or preferences
     (as in effect from time to time) relating to any series of preferred stock
     or (ii) any of the rights, preferences and privileges of any other class of
     capital stock, or the terms or provisions of any option or convertible
     security;

          (c) (i) create, authorize or issue any securities or shares of any
     such class or series of securities which rank senior to or on parity with
     the Series C Shares;


                                      -3-
<PAGE>

     (ii) create, authorize or issue any securities or shares of any such class
     or series of securities the holders of which have the right to cast more
     than one vote per share, and/or have the right, voting as a class or
     series, to elect one or more members of the Board of Directors; (iii)
     create, authorize or issue any securities or shares of any such class or
     series of securities convertible into, or exercisable, redeemable or
     exchangeable for, shares of any of the foregoing; (iv) increase or decrease

     decrease the authorized number of Series C Shares;

          (d) (i) initiate or suffer to exist any Liquidation Event with respect

                                      -4-

     amended on August 20,1999, (except that interest rate "spreads" may
     increase by no more than 50 basis points over prime and principal amounts
     advanced against accounts receivable or inventory (but no other amounts of
     principal) may increase or decrease provided that advance rates are no
     greater than those currently in effect); or

          (o) except for transactions on customary and reasonable terms, enter
     into any transaction with (i) any Affiliate of the Company, (ii) any
     employee of the Company, (iii) any holder of more than five percent (5%) of
     the outstanding capital stock of any class or series of capital stock of
     the Company, (iv) any member of the immediate family of any Person set
     forth in clauses (i), (ii) and (iii) above, or (v) any corporation,

     is a director, officer, trustee, partner or holder of more than five
     percent (5%) of the outstanding capital stock thereof.  For purposes of

     consist of the spouse, parents, children, siblings, mothers- and fathers-
     in-law, sons- and daughters-in-law, and brothers- and sisters-in-law of
     such Person.

     6.   Conversion Rights.
          -----------------

          (a) At Option of Holders.  Holders of Series C Shares may, at their
              --------------------
option, upon surrender of the certificates therefor, convert any or all of their
Series C Shares into fully paid and nonassessable shares of Common Stock at any
time. The right of holders of Series C Shares to convert their shares shall be
exercised by surrendering for such purpose to the Company or any transfer agent
for the Series C Shares, and at such other office or offices, if any, as the
Board of Directors may designate, certificates representing the Series C Shares
to be converted, duly endorsed in blank or accompanied by proper instruments of
transfer. Upon the surrender of certificates representing the Series C Shares to
be converted, the person converting such shares shall be deemed to be the holder
of record of the Common Stock (and such other securities and property as the
holders of Series C Shares may be entitled to upon the conversion thereof, as
hereinafter provided) issuable upon such conversion, and all rights with respect
to the Series C Shares surrendered shall forthwith terminate except the right to
receive the Common Stock or other securities, cash or other assets receivable
upon such conversion as herein provided.

          (b) Conversion Rate/Conversion Price.  In addition to the adjustments
              --------------------------------
required by Section 6(e), 6(f) and 6(g), the conversion of Series C Shares into
Common Stock shall be governed by the following: Series C Shares shall be
convertible into that number of fully paid and nonassessable shares of Common
Stock (calculated as to each


                                      -6-
<PAGE>

conversion to the nearest 1/100th of a share) as shall be determined by
multiplying the "Conversion Rate," determined as hereinafter provided, in effect
at the time of conversion by the product of (i) the number of shares of Series C
Shares to be converted and (ii) the "Initial Conversion Price" applicable to the
shares of Series C Shares being converted (as hereinafter defined) and dividing
the product of such multiplication by the "Conversion Price" applicable to the
Series C Shares being converted, determined as hereinafter provided, in effect
at the time of conversion and making any adjustments required by Section 6(e)
hereof. The Conversion Rate shall initially be one and shall be adjusted from
time to time as provided in Section 6(e) (such conversion rate, as so adjusted
from time to time, being referred to herein as the "Conversion Rate"). The
"Initial Conversion Price" for the Series C Shares shall be the price per Series
C Share paid to the Company upon the issuance thereof. The conversion price for
Series C Shares shall initially be equal to the Initial Conversion Price and
shall be adjusted from time to time as provided in Sections 6(f) and (g) (the
conversion price for Series C Shares, as so adjusted from time to time, being
herein referred to as the "Conversion Price" applicable to such Series C
Shares).

          (c) Reservation of Shares.  A number of shares of authorized but
              ---------------------
unissued Common Stock of the Company sufficient to provide for the conversion of
all of the Series C Shares outstanding upon the basis herein provided
("Conversion Common Stock") shall at all times be reserved by the Company, free
from preemptive rights, for such conversion. If the Company shall issue any
securities or make any change in its capital structure that would change the
number of shares of Common Stock into which each Series C Share shall be
convertible as herein provided, the Company shall at the same time also make
proper provision so that thereafter there shall be a sufficient number of
additional shares of capital stock authorized and reserved, free from preemptive
rights, for conversion of the outstanding Series C Shares on the new basis. The
Company shall comply with all securities laws regulating the offer and delivery
of shares of Common Stock upon conversion of Series C Shares and shall list such
shares on any national securities exchange on which the Common Stock is listed
or have such shares admitted for quotation on the Nasdaq National or Small Cap
Market if the Common Stock is admitted for quotation thereon.

          (d) Fractional Shares.  No fractional shares of Common Stock shall be
              -----------------
issued upon the conversion of Series C Shares but, in lieu of any fraction of a
share of Common Stock that would otherwise be issuable in respect of the
aggregate number of such shares surrendered for conversion at one time by the
same holder, the Company shall pay in cash an amount equal to the product of (a)
the "Closing Price" (as defined in the next sentence) of a share of Common Stock
on the last trading day before the relevant conversion date and (b) such
fraction of a share. The "Closing Price" for each day shall be the last reported
sale price regular way or, in case no sale takes place on such day, the average
of the closing bid and asked prices regular way on such day, in either case as
reported on the New York Stock Exchange Composite Tape, or, if the Common Stock
is not listed or admitted to trading on such Exchange, on the principal national
securities exchange on which the

                                      -7-
<PAGE>

Common Stock is listed or admitted to trading, or, if the Common Stock is not
listed or admitted to trading on any national securities exchange, on the Nasdaq
National or Small Cap Market, or, if the Common Stock is not admitted for
quotation on the Nasdaq National or Small Cap Market, the average of the high
bid and low asked prices on such day as recorded by the National Association of
Securities Dealers, Inc. through Nasdaq, or, if the National Association of
Securities Dealers, Inc. through Nasdaq shall not have reported any bid and
asked prices for the Common Stock on such day, the average of the bid and asked
prices for such day as furnished by any New York Stock Exchange member firm
selected from time to time by the Company for such purpose, or, if no such bid
and asked prices can be obtained from any such firm, the fair market value of
one share of the Common Stock on such day as determined in good faith by the
Board of Directors of the Company.

          (e) Conversion Rate Adjustments.  Subject to Section 6(g) hereof, if
              ---------------------------
the Company shall (A) subdivide its outstanding Common Stock into a greater
number of shares, (B) combine the shares of its outstanding Common Stock into a
smaller number of shares or (C) declare a dividend upon its shares of Common
Stock payable in shares of Common Stock, then in each such case the Conversion
Rate in effect immediately prior thereto shall be proportionately adjusted so
that the holder of any shares of any Series C Shares thereafter surrendered for
conversion shall be entitled to receive, to the extent permitted by applicable
law, the number and kind of shares of capital stock of the Company that such
holder would have owned or have been entitled to receive after the happening of
such event had such Series C Shares been converted immediately prior to the
record date for such event (or if no record date is established in connection
with such event, the effective date for such action). An adjustment pursuant to
this Section 6(e) shall become effective immediately after the record date in
the case of a stock dividend or distribution, or immediately after the effective
date in the case of a subdivision, combination or reclassification.

          (f) Initial, One-Time Conversion Price Adjustment.  The Company
              ---------------------------------------------
contemplates a registered offering of rights to purchase common stock to its
shareholders.  If the purchase price of such offering is less than $2.00 per
share, the Conversion Price shall be adjusted to such purchase price.  If the
Company abandons, or shall not have completed such registered offering to its
existing shareholders of rights to purchase Common Stock resulting in gross
proceeds equal to or exceeding $5,000,000 on or before June 30, 2000, the
Conversion Price shall be reduced to One Dollar ($1.00) per share, effective as
of March 31, 2000, and any transactions subsequent to March 31, 2000 shall, for
purposes of Section 6(g), be evaluated using that adjusted Conversion Price.

          (g) Continuing Conversion Price Adjustments. With respect to Series C
              ---------------------------------------
Shares, if and whenever the Company shall issue or sell any shares of its Common
Stock or any securities convertible into or exercisable or exchangeable for
shares of Common Stock ("Convertible Securities") for a consideration per share
(in the case of the sale of any Convertible Securities, the amount, if any,
payable for such Convertible Security and upon

                                      -8-
<PAGE>

the exercise or conversion thereof (and/or upon the exercise or conversion of
the securities receivable upon such exercise or conversion) for each share of
Common Stock receivable thereby shall be included in determining such
consideration per share) less than the Conversion Price applicable to the Series
C Shares, in effect immediately prior to the time of such issuance or sale,
then, forthwith upon such issuance or sale, such higher Conversion Price(s) for
the Series C Shares shall be reduced to a price (calculated to the nearest tenth
of a cent) determined by dividing (x) an amount equal to the sum of (A) the
number of shares of Common Stock outstanding immediately prior to such issuance
or sale multiplied by such higher Conversion Price plus (B) the aggregate
                                                   ----
consideration, if any, received or receivable by the Company for the share of
Common Stock issued or issuable upon the exercise of any issued Convertible
Security (and/or upon the exercise or conversion of the security receivable upon
such exercise or conversion), by (y) an amount equal to the sum of (A) the
number of shares of Common Stock outstanding immediately prior to such issuance
or sale plus (B) the number of shares of Common Stock thus issued or sold or
        ----
receivable upon the exercise or conversion of the Convertible Securities (or the
securities receivable upon the exercise or conversion of such Securities). If
any Convertible Securities taken into account in any such adjustment of a
Conversion Price subsequently expire without exercise, such Conversion Price
shall be recomputed to eliminate the effect of such expired Convertible
Securities. However, no adjustment pursuant to this Section 6(g) shall be
required upon the issuance of shares of Common Stock upon conversion of any
shares of preferred stock, including the Series C Shares, outstanding prior to
such issuance or sale or upon the exercise of options available under the 1996
Directors Stock Option Plan or the 1999 Long-term Incentive Plan of the Company
as in effect prior to November 1, 1999.

          (h) Consolidations, Mergers, Sales of Assets, Reclassifications and
              ---------------------------------------------------------------
Certain Dividends.  In case of any (A) consolidation or merger of the Company
- -----------------
with any other company (other than the merger of a subsidiary of the Company
into the Company in a transaction in which the Company is the surviving
corporation and the outstanding shares of capital stock of the Company are not
exchanged for or converted into any other securities, cash or other property),
(B) sale or transfer of all or substantially all of the assets of the Company
for cash, securities or other property, (C) any share exchange pursuant to which
all of the outstanding shares of Common Stock are converted into other
securities or property, or (D) issuance of any shares of the Company's capital
stock in connection with a reclassification of the Common Stock, the Company
shall, prior to or at the time of such transaction, make appropriate provision
or cause appropriate provision to be made so that the holders of each Series C
Share then outstanding shall have the right thereafter to receive the kind and
amount of shares of stock and other securities and property receivable upon such
consolidation, merger, sale, transfer, share exchange or reclassification by a
holder of the number of shares of Common Stock into which such Series C Shares
could have been converted immediately prior to the effective date of such
consolidation, merger, sale, transfer, share exchange or reclassification.  If
in connection with any such consolidation, merger, sale, transfer, share
exchange or reclassification, each holder of Common Stock is


                                      -9-
<PAGE>

entitled to elect to receive either securities, cash or other assets upon
completion of such transaction, the Company shall provide or cause to be
provided to each holder of Series C Shares the right to elect the securities,
cash or other assets into which the Series C Shares held by such holder shall be
convertible after completion of any such transaction on the same terms and
subject to the same conditions applicable to holders of the Common Stock
(including, without limitation, notice of the right to elect, limitations on the
period in which such election shall be made and the effect of failing to
exercise the election).

          (i) Rounding.  All calculations hereunder, unless otherwise specified,
              --------
shall be made to the nearest cent or to the nearest 1/100th of a share, as the
case may be.

          (j) Notices.  Whenever the Conversion Rate or a Conversion Price is
              -------
adjusted as herein provided, the Company shall give prompt notice by mail to the
holders of the outstanding Series C Shares of such adjustment, which notice
shall set forth the adjustment and the new Conversion Rate or Conversion Price.
Notwithstanding the foregoing, failure by the Company to give such notice or a
defect in such notice shall not affect the binding nature of such corporate
action of the Company.

          (k) Common Stock Defined.  As used herein, the term "Common Stock"
              --------------------
shall mean and include the presently authorized Common Stock of the Company and
shall also include any capital stock of any class of the Company (other than the
Series C Shares) hereafter authorized which shall have the right to vote on all
matters submitted to the shareholders of the Company and shall not be limited to
a fixed sum or percentage in respect of the rights of the holders thereof to
participate in dividends or in the distribution of assets upon the occurrence of
any Liquidation Event of the Company.

     7.   Preemptive Rights.  If Company offers to sell its common stock,
          -----------------
securities convertible into common stock, or any other debt (excluding debt
securities issued to banks or other financial institutions) or equity securities
other than the issuance of options or shares to employees, directors and
consultants which have been approved by the directors elected by the Series B
Preferred Stock (the "Additional Securities") it will first offer to the holders
of the Series C Shares, or, if applicable, Conversion Common Stock the right to
purchase a portion of the Additional Securities such that such holders'
aggregate percentage ownership of the Company on a fully diluted basis
("Purchasers' Percentage") will be unchanged. The offer shall set forth the
number of shares to be sold, the price, and material terms and conditions.

The right of the holders to purchase in the aggregate Additional Securities up
to but not more than the Purchaser's Percentage may be exercised as follows:

          (a) the Company shall provide each holder with written notice of the
number of securities to be issued and the cash price therefor;


                                     -10-
<PAGE>

          (b) each holder shall have the right to purchase that percentage of
such securities equal to the ratio that the number of shares of Conversion
Common Stock held by such holder bears to the total number of shares of
Conversion Common Stock held by all holders;

          (c) second, if not all holders elect to purchase their pro rata share,
then as to the excess of the amount of Purchaser's Percentage over the shares
taken by holders electing to purchase their pro rata part (such excess to be
referred to as the "Unsubscribed Shares"), the holders who do so elect shall be
offered the right to acquire pro rata among themselves based on their holdings
of Conversion Common Stock; and

          (d) if after such offer, any of the Unsubscribed Shares remain unsold,
as to such unsold Unsubscribed Shares, as the holders who agreed to purchase
their pro rata part of the Unsubscribed Shares may agree, all within thirty (30)
days of notice by the Company of such proposed issuance.

          The Company may, within thirty (30) days, sell the remaining
securities not to be purchased by the holders to third parties on the terms and
conditions set forth in the offer delivered to holders, and the holders shall be
required to deliver the consideration to Company for the securities being
purchased by the holders at the same time such third parties are required to
deliver their consideration to Company.

          Notwithstanding anything in this Section 7 to the contrary, the
holders' rights under this Section 7 shall not apply to (i) the securities of
the Company outstanding immediately prior to the issuance of the initial Series
C Shares; (ii) shares of common stock issued in connection with any stock split,
stock dividends or recapitalization of Company or upon conversion of the Series
C Shares; (iv) any borrowings, direct or indirect from financial institutions by
the Company, whether or not presently authorized, evidenced by any type of debt
instrument with no equity features; (v) securities issued pursuant to an
effective registration statement filed with the SEC in connection with a
registered public offering; (vi) equity securities issued to a financial
institution in connection with any lease financing or debt financing of the
Company approved by a two-thirds (2/3) vote of the Board of Directors; or (vii)
any transaction in which all directors of the Company elect for this Section 7
not to apply.

                                   TO PURCHASE
                             SHARES OF COMMON STOCK


         For value received, and in consideration of the execution and delivery
of the Commitment Letter between the issuer of this Warrant and Industrial-Works
Holding Co., LLC., a Delaware corporation dated February 18, 2000 ("Commitment
Letter"), Purchaser and its successors or assigns ("Holder"), is entitled to
purchase from FieldWorks, Incorporated, a Minnesota corporation (the "Company'),
up to 100,000 fully paid and nonassessable shares of the Company's common stock,
$.001 par value per share or such greater or lesser number of such shares as may
be determined by application of the anti-dilution provisions of this Warrant, at
the price of One Dollar $1.00 per share, subject to adjustment as noted below
(the "Warrant Exercise Price").

         This Warrant may be exercised by Holder at any time or from time to
time, and shall remain exercisable until the fifth anniversary of the date
hereof. This Warrant, and any portion hereof, shall expire if not exercised
within such five-year period.

         This Warrant is subject to the following terms and conditions:

         1. Exercise. The rights represented by this Warrant may be exercised by
the Holder, in whole or in part, by written election, in the form set forth
below, by the surrender of this Warrant (properly endorsed if required) at the
principal office of the Company, and by payment to it by cash, certified check
or bank draft of the Warrant Exercise Price for the shares to be purchased. The
shares so purchased shall be deemed to be issued as of the close of business on
the date on which this Warrant has been exercised by payment to the
<PAGE>

Company of the Warrant Exercise Price. Certificates for the shares of stock so
purchased, bearing the restrictive legend set forth at the end of this Warrant,
shall be delivered to Holder within fifteen (15) days after the rights
represented by this Warrant shall have been so exercised, and, unless this
Warrant has expired, a new warrant representing the number of shares, if any,
with respect to which this Warrant remains exercisable shall also be delivered
to Holder hereof within such time. No fractional shares shall be issued upon any
exercise of this Warrant.

         2. "Cashless" Exercise. At Holder's option, all or any portion of the
Warrant Exercise Price may be paid by surrendering a portion of the shares
issuable upon exercise of this Warrant. The value of the shares so surrendered
shall be the closing price of the Company's common stock on the date of Holder's
notice of exercise.

         3. Shares. All shares that may be issued upon the exercise of the
rights represented by this Warrant shall, upon issuance, be duly authorized and
issued, fully paid and nonassessable shares. During the period within which the
rights represented by this Warrant may be exercised, the Company shall at all
times have authorized and reserved for the purpose of issue or transfer upon
exercise of the subscription rights evidenced by this Warrant a sufficient
number of shares of its common stock to provide for the exercise of the rights
represented by this Warrant.

         4. Adjustment. The Warrant Exercise Price shall be subject to
adjustment from time to time as hereinafter provided in this Section 4:

                  (a) If the Company at any time divides the outstanding shares
         of its common stock into a greater number of shares (whether pursuant
         to a stock split, stock dividend or otherwise), and conversely, if the
         outstanding shares of its common stock are combined into a smaller
         number of shares, the Warrant Exercise Price in effect immediately
         prior to such division or combination shall be proportionately adjusted
         to reflect the reduction or increase in the value of each such common
         share.

                  (b) If any stock dividend, capital reorganization or
         reclassification of the capital stock of the Company, or consolidation
         or merger of the Company with another corporation, or the sale of all
         or substantially all of its assets to another corporation shall be
         effected in such a way that holders of the Company's common stock shall
         be entitled to receive stock, securities or assets with respect to or
         in exchange for such common stock, then, as a condition of such stock
         dividend, reorganization, reclassification, consolidation, merger or
         sale, Holder shall have the right to purchase and receive upon the
         basis and upon the terms and conditions specified in this Warrant and
         in lieu of the shares of the common stock of the Company immediately
         theretofore purchasable and receivable upon the exercise of the rights
         represented hereby, such shares of stock, other securities or assets as
         would

                                      -2-
<PAGE>

         have been issued or delivered to the Holder if Holder had exercised
         this Warrant and had received such shares of common stock immediately
         prior to such stock dividend, reorganization, reclassification,
         consolidation, merger or sale. The Company shall not effect any such
         consolidation, merger or sale unless prior to the consummation thereof
         the successor corporation (if other than the Company) resulting from
         such consolidation or merger or the corporation purchasing such assets
         shall assume by written instrument executed and mailed to Holder at the
         last address of Holder appearing on the books of the Company the
         obligation to deliver to Holder such shares of stock, securities or
         assets as, in accordance with the foregoing provisions, Holder may be
         entitled to purchase.

                  (c) If and whenever the Company shall (1) issue or sell any
         shares of its common stock for a per-share consideration less than the
         Warrant Exercise Price in effect immediately prior to the time of such
         issuance or sale, (2) issue or sell any warrants, options or other
         rights to acquire shares of its common stock at a purchase price less
         than the Warrant Exercise Price in effect immediately prior to the time
         of such issuance or sale, or (3) issue or sell any other securities
         that are convertible into shares of its common stock for a purchase or
         exchange price less than the Warrant Exercise Price in effect
         immediately prior to the time of such issuance or sale (except for the
         issuance or sale of shares of the Company's common stock pursuant to
         stock option plans, stock purchase plans or other employee stock
         incentive programs adopted by the Company's Board of Directors, or
         pursuant to business acquisition or lease financing transactions),
         then, upon such issuance or sale, the Warrant Exercise Price shall be
         reduced to the price (calculated to the nearest cent) determined by
         dividing (A) an amount equal to the sum of (1) the number of shares of
         the Company's common stock outstanding immediately prior to such issue
         or sale multiplied by the then existing Warrant Exercise Price and (2)
         the consideration, if any, received by the Company upon such issue or
         sale plus the consideration to be received by the Company upon the
         exercise of such stock purchase rights by (B) an amount equal to the
         sum of (1) the number of shares of its common stock outstanding
         immediately prior to such issue or sale and (2) the number of its
         shares of common stock thus issued or sold or issuable or saleable upon
         the exercise of such purchase rights or the conversion of such
         convertible securities; provided, however, that in the event that any
         such purchase right expires or is terminated prior to the exercise of
         this Warrant, the Warrant Exercise Price shall be recalculated by
         deleting such purchase right and provided further that if an adjustment
         is made to the Warrant Exercise Price as a result of the issuance or
         sale of any such purchase rights or convertible securities, no further
         adjustment shall be made to the Warrant Exercise Price at the time such
         purchase rights are exercised or convertible securities are converted.

                  (d) Upon any adjustment of the Warrant Exercise Price, Holder
         shall thereafter be entitled to purchase, at the Warrant Exercise Price
         resulting from such

                                      -3-
<PAGE>

         adjustment, the number of shares obtained by multiplying the Warrant
         Exercise Price in effect immediately prior to such adjustment by the
         number of shares purchasable pursuant hereto immediately prior to such
         adjustment and dividing the product thereof by the Warrant Exercise
         Price resulting from such adjustment.

                  (e) Upon any adjustment of the warrant exercise price, the
         Company shall give written notice thereof to Holder, stating the
         Warrant Exercise Price resulting from such adjustment and the increase
         or decrease, if any, in the number of shares purchasable at such price
         upon the exercise of this Warrant, setting forth in reasonable detail
         the method of calculation and the facts upon which such calculation is
         based.

         5. No Rights as Shareholder. This Warrant shall not entitle Holder to
any voting rights or other rights as a shareholder of the Company.

         6. Registration Rights. Holder shall be entitled to certain demand
registration rights and also entitled to participate in any registered offering
of shares of the Company's common stock. Holder's participation in any such
offering shall be in accordance with the procedures, and subject to the
limitations, set forth on Exhibit A to this Warrant.

         7. Transfer. This Warrant and all rights hereunder are transferable, in
whole or in part, at the principal office of the Company by the holder hereof in
person or by duly authorized attorney, upon surrender of this Warrant properly
endorsed to any person or entity who represents in writing that such person or
entity is acquiring the Warrant for investment and without any view to the sale

the rights represented by this Warrant, or to the transfer hereof on the books
of the Company, any notice to the contrary notwithstanding; but until such
transfer on such books, the Company may treat the registered owner hereof as the
owner for all purposes.

                                       TO
                                     WARRANT
                                    ISSUED BY
                            FIELDWORKS, INCORPORATED

          "Eligible Holders" means each of Industrial-Works Holding Co., LLC and
     any Person to whom it transfers any Registrable Securities, or any of their
     respective Permitted Transferees.

          "Holder" means (i) any person owning of record Registrable Securities
     that have not been sold to the public or (ii) any transferee of record of
     such Registrable Securities in accordance with Section 7 of the Warrant.

          "Register," "registered," and "registration" refer to a registration

     above-described securities. Notwithstanding the foregoing, Registrable
     Securities shall not include any securities sold by a person to the public

     the Company in connection with the termination of the Securities Purchase

     2. Demand Registrations

          (a) Required Threshold.

          Any Eligible Holder owning at least One Hundred Sixty-Five Thousand
     (165,000) Common Stock Equivalents (as such number may be equitably
     adjusted from time to time to reflect any stock split, stock dividend,
     recapitalization, reclassification, consolidation or the like) may request
     (such Person, the "Initiating Holder") that the Company file a Registration
     Statement under the Securities Act on an appropriate form with respect to
     at least fifty percent (50%) of the Registrable Securities owned by such
     Initiating Holder (which form shall be available for the sale of the
     Registrable Securities in accordance with the intended method or methods of
     distribution thereof and shall include all financial statements required by
     the SEC to be filed herewith) covering the shares of Registrable Securities
     that are the subject of such request and the Company shall file such a
     Registration Statement.

          (b) Number of Demand Registrations.

          The Company shall be obligated to prepare, file and cause to become
     effective pursuant to this Section 2 only one (1) Registration Statement in
     the aggregate pursuant to Section 2(a) above for the Eligible Holders;
     provided, however, that a Registration Statement shall not be counted as
     the Demand Registration hereunder unless it becomes effective and is
     maintained effective in accordance with the requirements specified in
     Section 6(a); provided, further, that if there is an underwriter's cutback
     pursuant to Section 2(e) with respect to the request for registration
     initiated by an Eligible Holder, such requested registration shall not be
     deemed to be the Demand Registration.

                                       A-2
<PAGE>

          (c) Deferral by Company.

          Notwithstanding anything in this Section 2 to the contrary, the
     Company shall not be obligated to prepare, file and cause to become
     effective pursuant to this Section 2 a Registration Statement if within
     five (5) days of receipt of a request for a Demand Registration the Company
     furnishes to the Initiating Holder a certificate signed by the Chief
     Executive Officer of the Company that, in the good faith judgment of the
     Board of Directors, it would be detrimental in any material respect to the
     Company and its shareholders for the Company to comply with the Demand
     Registration, and it is therefore essential to defer the filing of the
     Registration Statement relating thereto. Any such deferral shall be for a
     period of not more than six (6) months after the Company's receipt of the
     Initiating Holder's written request for registration pursuant to this
     Section 2; provided, however, that the Company may not exercise this right
     more than once with respect to the Demand Registration and that any
     requested registration deferred, and not ultimately effected, by the
     Company pursuant to the provisions of this Section 2(c) shall thereafter
     not be deemed to be the Demand Registration for purposes of the Section
     2(a) above.

          (d) Participation.

          The Company shall promptly give written notice to all other Eligible
     Holders upon receipt of a request for a Demand Registration pursuant to
     Section 2(a) above. Such other Eligible Holders may, by written notice to
     the Company and the Initiating Holder, within thirty (30) business days of
     the Company's notice, elect to join in a request for a Demand Registration
     pursuant to Section 2(a) above, with respect to any number of shares of
     Registrable Securities owned by such Eligible Holder. The Registrable
     Securities of the other Eligible Holders being offered in such Demand
     Registration shall be treated pari passu with the Registrable Securities
     being offered by the Initiating Holder for all purposes including
     "underwriter's cutbacks" under subsection (e) of this Section and any such
     request by an Eligible Holder shall not be treated as either a request by
     such Eligible Holder for a Piggyback Registration under Section 3 or as a
     request by such Eligible Holder for a Demand Registration under this
     Section 2. The Company shall include in such Demand Registration such
     shares of Registrable Securities for which it has received written requests
     to register such shares within thirty (30) days after such written notice
     has been given, provided that all the Registrable Securities for which the
     Initiating Holder and the other Eligible Holders have requested
     registration shall be covered by such registration statement before any
     other securities are included.

          In addition, the Company shall promptly give written notice to all
     eligible Holders upon receipt of a request for a demand registration by any
     Person (such Person, the "Initiating Person") pursuant to any other
     registration rights agreement with the Company (whether such other
     registration rights agreement is entered into before or after the date
     hereof). Each Eligible Holder may, by written notice to the Company, within
     thirty (30)

                                       A-3
<PAGE>

     business days of the Company's notice, elect to request a Demand
     Registration pursuant to Section 2(a) above, with respect to any shares of
     Registrable Securities owned by such Eligible Holder. The Registrable
     Securities of the Eligible Holders being offered in such Demand
     Registration shall be treated pari passu with the registrable securities
     being offered by the Initiating Person for all purposes including
     "underwriter's cutbacks" and any such request by an Eligible Holder shall
     not be treated as either a request by such Eligible Holder for a Piggyback
     Registration under Section 3 or as a request by such Eligible Holder for a
     Demand Registration under this Section 2. The Company shall include in such
     demand registration such shares of Registrable Securities for which it has
     received written requests to register such shares within thirty (30) days
     after such written notice has been given, provided that all the Registrable
     Securities for which the Initiating Person and the Eligible Holders have
     requested registration shall be covered by such registration statement
     before any other securities are included.

          (e) Underwriter's Cutback.

          If the public offering of Registrable Securities is to be underwritten
     and, in the good faith judgment of the managing underwriter, the inclusion
     of all the Registrable Securities requested to be registered hereunder
     would interfere with the successful marketing of such shares of Registrable
     Securities, the number of shares of Registrable Securities to be included
     shall be reduced and the number of shares to be included in the
     underwriting or registration shall be allocated first among the Eligible
     Holders pro rata upon the basis of the number of shares of Registrable
     Securities sought to be offered by the Eligible Holders pursuant to such
     Demand Registration and any remainder shall be allocated among the Company
     and the other persons entitled to incidental registrations pro rata upon
     the basis of the number of shares of Registrable Securities sought to be
     registered thereby. If a person who has requested inclusion in such Demand
     Registration does not agree to the terms of any such underwriting, such
     person shall be excluded therefrom by written notice from the Company, the
     underwriter or the Initiating Holder, and the securities owned by such
     person(s) shall be withdrawn from registration (the "Withdrawn
     Securities").

          If there are any Withdrawn Securities as a result of an Underwriter's
     Cutback, then the Company shall offer to those persons who have retained
     rights to include securities in the Demand Registration the right to
     include additional securities in the registration in an aggregate amount
     equal to the number of Withdrawn Securities that would have been included
     in the Demand Registration after giving effect to the Underwriter's Cutback
     had such securities not been withdrawn, with such shares to be allocated
     among such persons in accordance with the allocation of rights set forth in
     this paragraph (e).

          (f) Managing Underwriter.

          The managing underwriter or underwriters of any Underwritten Offering
     covered by a Demand Registration shall be selected by a majority in
     interest of the Eligible

                                       A-4
<PAGE>

     Holders participating in such Underwritten Offering and shall be reasonably
     acceptable to the Company. The right of any other Holders joining in a
     request for registration as provided in Section 2(d) above to registration
     pursuant to this Section 2 shall be conditioned upon such Holder's
     participation in such underwriting and the inclusion of such Holder's
     Registrable Securities in the underwriting on the same terms as those of
     the Initiating Holder (unless otherwise mutually agreed by a majority in
     interest of the Eligible Holders participating in such registration and
     such Holder with respect to such participation and inclusion).

     3. Piggyback Registrations

          (a) Participation.

          Each time the Company decides to file a Registration Statement under
     the Securities Act (other than registrations on Forms S-4 or S-8 or any
     successor form thereto, and other than a Demand Registration or a demand
     registration by an Initiating Person) covering the offer and sale by it or
     any of its security holders of any of its securities for money, the Company
     shall give written notice thereof to all Eligible Holders. The Company
     shall include in such Registration Statement such shares of Registrable
     Securities for which it has received a written request from any Eligible
     Holder to register such shares within twenty (20) days after such written
     notice has been given. If the Registration Statement is to cover an
     Underwritten Offering, such Registrable Securities shall be included in the
     underwriting on the same terms and conditions as the securities otherwise
     being sold through the underwriters.

          (b) Underwriter's Cutback.

          Subject to the requirements of Section 12 hereof, if in the good faith
     judgment of the managing underwriter of such offering the inclusion of all
     of the shares of Registrable Securities and any other Common Stock
     requested to be registered would interfere with the successful marketing of
     such shares, then the number of shares of Registrable Securities and other
     Common Stock to be included in the offering shall be reduced, with the
     participation in such offering to be in the following order of priority:
     (1) first, the shares of Common Stock which the Company proposes to sell
     for its own account, (2) second, the shares of Registrable Securities of
     all Eligible Holders requested to be included, and (3) third, any other
     shares of Common Stock requested to be included. Any necessary allocation
     among the Holders of shares within each of the foregoing groups shall be
     pro rata among such Holders requesting such registration based upon the
     number of shares of Common Stock and Registrable Securities owned by such
     Holders.

          (c) Company Control.

          The Company may decline to file a Registration Statement after giving
     notice to Eligible Holders pursuant to Section 3(a) above, or withdraw a
     Registration Statement after filing and after such notice, but prior to the
     effectiveness thereof; provided that the

                                       A-5
<PAGE>

     Company shall promptly notify each Eligible Holder in writing of any such
     action and provided further that the Company shall bear all expenses
     incurred by each Eligible Holder or otherwise in connection with such
     withdrawn Registration Statement.

     4. Registration on Form S-3

          (a) Right to Request Registrations on Form S-3.

          After the Company has qualified for the use of Form S-3, in addition
     to the rights contained in the foregoing provisions of this Agreement, the
     Eligible Holders shall have the right to request registrations on Form S-3
     or any comparable or successor form. Each such request shall be in writing
     and shall state the anticipated number of shares of Registrable Securities
     to be disposed of and the anticipated gross proceeds of such shares, and
     the intended methods of disposition of such shares by such Eligible Holder
     or Eligible Holders, including whether such resales are to be made on a
     delayed or continuous basis pursuant to Rule 415. The Company shall not be
     obligated to effect any registration pursuant to this Section 4 if (i) the
     Eligible Holders propose to sell Registrable Securities representing less
     than fifteen percent (15% ) of the shares of the Registrable Securities
     then held by all Eligible Holders or (ii) the circumstances described in
     Section 2(c) shall apply (but subject to the limitations set forth
     therein).

          (b) Application of Certain Provisions.

          If the registration is for an Underwritten Offering, the provisions of
     Sections 2(d) and 2(f) hereof shall also apply to such registration, except
     the Company may not include any shares for its own account.

     5. Hold-back Agreements

          (a) By Holders of Registrable Securities.

          Upon the written request of the managing underwriter of any
     Underwritten Offering of the Company's securities, a Holder of Registrable
     Securities shall not sell or otherwise dispose of any Registrable
     Securities (other than those included in such registration) without the
     prior written consent of such managing underwriter for a period (not to
     exceed thirty (30) days before the effective date and one hundred twenty
     (120) days thereafter) that such managing underwriter reasonably determines
     is necessary in order to effect the Underwritten Offering; provided that
     each of the officers and directors of the Company, and each Holder of more
     than one percent (1%) of the Common Stock of the Company, shall have
     entered into substantially similar holdback agreements with such managing
     underwriter covering at least the same period.

                                       A-6
<PAGE>

          (b) By the Company and Others.

          The Company agrees:

               (1) not to effect any public or private sale or distribution of
          any of its equity securities during the 30-day period prior to, and
          during the 120-day period after, the effective date of each
          Underwritten Offering made pursuant to a Demand Registration or a
          Piggyback Registration, if so requested in writing by the managing
          underwriter (except as part of such Underwritten Offering, pursuant to
          registrations on Forms S-4 or S-8 or any successor forms thereto), and

               (2) not to issue any Equity Securities other than for sale in a
          registered public offering unless each of the Persons to which such
          securities are issued has entered a written agreement binding on its
          transferees not to effect any public sale or distribution of such
          securities during such 130-day period, including without limitation a
          sale pursuant to Rule 144 under the Securities Act (except as part of
          such Underwritten Registration, if and to the extent permitted
          hereunder).

     6. Registration Procedures

     If and whenever the Company is required to register Registrable Securities
pursuant to this Agreement, the Company will use all commercially reasonable
efforts to effect such registration to permit the sale of such Registrable
Securities in accordance with the intended plan of distribution thereof and will
as expeditiously as practicable:

          (a) prepare and file with the SEC as soon as practicable a
     Registration Statement with respect to such Registrable Securities and use

     Statement and the underwriters, if any, draft copies of all such documents
     proposed to be filed, which documents will be subject to the review of each
     Eligible Holder and such underwriters, and the Company shall not file any
     Registration Statement or amendment thereto or any Prospectus or any
     supplement thereto to which the Eligible Holders or the underwriters, if
     any, shall reasonably object;

          (b) prepare and file with the SEC such amendments and post-effective
     amendments to the Registration Statement, and such supplements to the

     intended plan of distribution set forth in such Registration Statement or
     supplement to the Prospectus;

          (c) promptly notify the selling Holders of Registrable Securities and

          amendment has been filed, and, with respect to the Registration
          Statement or any post-effective amendment, when the same has become
          effective,

               (2) of any request by the SEC for amendments or supplements to
          the Registration Statement or the Prospectus or for additional
          information,

               (3) of the issuance by the SEC of any stop order suspending the
          effectiveness of the Registration Statement or the initiation of any
          proceedings for that purpose,

               (4) if at any time the representations and warranties of the
          Company contemplated by clause (1) of paragraph (o) below cease to be
          accurate in all material respects,

               (5) of the receipt by the Company of any notification with
          respect to the suspension of the qualification of the Registrable
          Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose, and

               (6) of the existence of any fact which results in the
          Registration Statement, the Prospectus or any document incorporated
          therein by reference containing a misstatement;

          (d) make all commercially reasonable efforts to obtain the withdrawal
     of any order suspending the effectiveness of the Registration Statement at
     the earliest practicable time;

          (e) unless the Company objects in writing on reasonable grounds, if
     requested by the managing underwriter or any Eligible Holder holding more
     than twenty-five percent (25%) of the Registrable Securities then
     outstanding, as promptly as practicable incorporate in a supplement or
     post-effective amendment such information as the managing underwriter and
     such Eligible Holder agree should be included therein relating to the sale
     of the Registrable Securities, including, without limitation, information
     with respect to the

                                       A-8

     number of shares of Registrable Securities being sold to underwriters, the

     any other terms of the Underwritten Offering of the Registrable Securities
     to be sold in such offering; and make all required filings of such
     supplement or post-effective amendment as soon as notified of the matters
     to be incorporated in such supplement or post-effective amendment;

          (f) only with respect to Demand Registrations, promptly prior to the

     by each of the selling Holders of Registrable Securities and the

     Registrable Securities covered by such Prospectus (or preliminary

     qualification of such Registrable Securities for offer and sale under the
     securities or blue sky laws of such jurisdictions as such underwriters may
     designate in writing and do anything else necessary or advisable to enable
     from a legal perspective the disposition in such jurisdictions of the
     Registrable Securities covered by the Registration Statement; provided that
     the Company shall not be required to qualify generally to do business in
     any jurisdiction where it is not then so qualified or to take any action
     which would subject it to general service of process in any such
     jurisdiction where it is not then so subject;

          (j) cooperate with the selling Holders of Registrable Securities and
     the managing underwriter, if any, to facilitate the timely preparation and

     misstatement, prepare a supplement or post-effective amendment to the

               (2) obtain opinions of counsel to the Company and updates thereof
          (which counsel and opinions (in form, scope and substance) shall be
          reasonably satisfactory to the managing underwriter, if any, and each
          Eligible Holder) addressed to each selling Holder and the underwriter,
          if any, covering the matters customarily covered in opinions delivered
          to holders and underwriters, respectively, in similar Underwritten
          Offerings and such other matters as may be reasonably requested by any

          Company's independent certified public accountants addressed to the
          selling Holders of Registrable Securities and the underwriters, if

          Offerings;

               (4) if an underwriting agreement is entered into, cause the same

development, manufacture or sale of any product or proposed product or the

Company has no reason to believe there will be any such employment or
violation. None of the execution or delivery of this Agreement, or the carrying
on of the business of the Company, or the conduct or proposed conduct of the
business of the Company will conflict with or result in a breach of the terms,
conditions or provisions of or constitute a default under any contract,

best of the Company's knowledge, threatened on the ground that the operations
of the Company infringe upon or conflict with the asserted rights of any other
Person under any Intellectual Property, and to the best of the Company's
knowledge, there is no basis for any such claim (whether or not pending or
threatened). No claim is pending or, to the best of the Company's knowledge,
threatened on the ground that any such Intellectual Property owned or licensed
by the Company, or which the Company otherwise has the right to use, is invalid
or unenforceable by the Company and there is no basis for any such claim
(whether or not pending or threatened). To the best of the Company's knowledge,
all technical information developed by and belonging to the Company which has
not been patented has been kept confidential, except for instances of non-
compliance which would not have a Material Adverse Effect.

from, or otherwise materially adversely affect the Company in, conducting its
business in any jurisdiction in which it proposes to conduct business.

   (b) The Company has, and, to the Company's knowledge after due inquiry, all
professional employees or agents of the Company have, all licenses, franchises,

<PAGE>

negotiated with respect thereto with, any Person or Persons, and neither the
Company nor any Person acting on its behalf has taken or will take any other
action (including, without limitation, any offer, issuance or sale of any
security of the Company under circumstances which might require the integration
of such security with the Series B Shares or the Warrant under the Securities
Act of 1933 (the "Securities Act") or the rules and regulations of the
Commission thereunder), in either case so as to subject the offering, issuance
or sale of the Series B Shares or the Warrant to the registration provisions of
the Securities Act.

   SECTION 2.16 Brokers. The Company has no contract, arrangement or
understanding with any broker, finder or similar agent with respect to the
transactions contemplated by this Agreement.

and such agreements are in full force and effect. No officer or key employee of
the Company has advised the Company (orally or in writing) that he or she
intends to terminate employment with the Company. The Company has never had any
employees represented by collective bargaining agreements. The Company is
currently in compliance with all Applicable Laws relating to the employment of
labor, including provisions relating to employment practices, terms and
conditions of employment, wages, hours, equal opportunity, collective
bargaining and the payment of Social Security and other taxes, and with ERISA.
There is no unfair labor practice charge or complaint against the Company
pending before the National Labor Relations Board or any other governmental
agency arising out of the activities of the Company of which the Company has
received notice or of which the Company has knowledge, and the Company has no
knowledge of any facts or information which would give rise thereto. There is
no labor strike or labor disturbance pending or, to the knowledge of the
Company, threatened against the Company. No collective bargaining
representation petition is pending or, to the knowledge of the Company,

   SECTION 2.19 Year 2000. The disclosure under the heading "Year 2000" in the
Company's Quarterly Report on Form 10-Q for the fiscal quarter ended October 3,
1999 (the "99Q3 Quarterly Report") is complete and accurate in all material
respects. The Company has no reasons to believe that it will incur expenses
after the date hereof in an amount in excess of $100,000 in the aggregate as a
result of problems commonly referred to as "Year 2000" software problems with
respect to the products, internal computer systems, non-computer operations or
productions processes of the Company or its vendors, business partners or
customers.

   SECTION 2.20 Taxes. The Company has filed, or caused to be filed, on a

related to its employees and independent contractors) required to be filed with
any federal or state governmental body and all material tax returns required to
be filed with any local or municipal governmental body, all such tax returns
are true, correct and complete in all material respects and the Company, has
paid or caused to be paid all taxes, levies, assessments, tariffs, duties or
other fees and any interest and penalties thereon ("Taxes") imposed, assessed
or collected by any governmental body that may have become due and payable
pursuant to those tax returns or otherwise. No such federal, state, local or
municipal tax returns have ever been audited by the Internal Revenue Service,
state or other authorities (except for an audit of state sales and use tax
returns). No deficiency assessment with respect to or proposed adjustment of
any of the Company's Federal, state, municipal or local tax returns has
occurred or, to the Company's knowledge, is threatened (except for a deficiency
assessment following the most recent audit of sales and use tax returns, which
the Company has fully satisfied). There has been no tax lien imposed by any
governmental body outstanding against the business or the Company's assets or
properties, except liens for current taxes not yet due. The reserve for Taxes
on the balance sheet in the Financial Statements is fully adequate to cover all
liabilities for Taxes with respect to periods ending on or before the Closing
Date. The transactions contemplated by this Agreement will not, assuming
compliance by parties to all Transaction

                                        8

compensation arrangements, incentive programs or arrangements, sick leave,
severance pay policies, salary continuation for disability, consulting
arrangements, workers' compensation, retirement, deferred compensation, bonus,
stock purchase, hospitalization, medical insurance, life insurance, tuition
reimbursement or scholarship programs, plans providing benefits or payments in
the event of a change of control, change in ownership, or sale of a substantial
portion of the Company's assets, maintained by the Company (including ERISA
Affiliates as defined below) or to which the Company or an ERISA Affiliate has
contributed or is or was obligated to make payments, in each case with respect
to any current or former employee or director of the Company or an ERISA
Affiliate. The Company has no employee pension benefit plans (as defined in
Section 3(2) of ERISA) ("Employee Pension Plans"). The Company, including its
ERISA Affiliates, does not and has never maintained or participated in, been
obligated to make contributions to, and does not have and has had no liability
with respect to, any Employee Benefit Plan which is: (i) subject to Title IV of
ERISA or the minimum funding requirements of Section 412 of the Code or Section
302 of ERISA, (ii) a "multi-employer plan" (as defined in Section 3(37) of
ERISA), (iii) a "multiple employer plan" (as defined in Section 4063 or 4064 of
ERISA), or (iv) a funded vacation pay plan. The Company and its ERISA
Affiliates have, with respect to each Employee Benefit Plan, complied in all
material aspects with all applicable laws, and the lawful terms of such plans.
No employee of the Company nor any fiduciary with respect to the Employee
Benefit Plans has issued or distributed any written communication to any
present or former employee of the Company regarding the effect the transactions
contemplated by this Agreement may have on any Employee Benefit Plan or other
employee-related practice, policy, or arrangement. There shall be no payment,
accrual of additional benefits, acceleration of payments, vesting or term
extension of any benefit under any Employee Benefit Plan or any agreement or
arrangement solely by reason of entering into or in connection with the
transactions contemplated by this Agreement. No Employee Benefit Plan has
participated in, engaged in or been a party to any non-exempt prohibited
transaction as described under the Code or ERISA, and neither the Company nor
any of its ERISA Affiliates has had asserted against them any claim for taxes
under Chapter 43 of Subtitle D of the Code and Section 5000 of the Code, or for
penalties under ERISA Section 502(c), (i) or (l), with respect to any Employee
Benefit Plan nor, to the knowledge of the Company, is there a basis for any
such claim. No officer, director or employee of the Company has committed a
material breach of any responsibility or obligation imposed upon fiduciaries by
Title I of ERISA with respect to any Employee Benefit Plan. Other than routine
claims for benefits, there is no claim pending or, to the knowledge of the
Company, threatened, involving any Employee Benefit Plan by any Person against
such plan, the Company or any of its ERISA Affiliates. There is no pending or,
to the knowledge of the Company, threatened, proceeding involving any Employee
Benefit Plan before any governmental agency. In accordance with applicable law
and the terms of such plan, each Employee Benefit Plan can be amended or
terminated at any time, without consent from any other party. With respect to
the Employee Benefit Plans, individually and in the aggregate, no event has
occurred, and to the knowledge of the Company, there exists no condition or set

Warrant is issued. The obligation to reserve shares in connection with the

terminated if, after ten (10) business days' notice, the party in breach has
not either cured such breach or commenced diligent efforts to cure such breach.

   Termination of this Agreement shall not waive any party of liability for
breaches of this Agreement which occurred prior to termination. If this
Agreement is terminated by Purchaser pursuant to subsection (b) of this Section
6.03, the limitation on expenses payable pursuant to Section 6.01 shall be
$85,000.

                            FIELDWORKS, INCORPORATED

                      RESOLUTION ESTABLISHING THE SERIES,
                    SETTING FORTH THE DESIGNATION AND FIXING
                     THE RELATIVE RIGHTS AND PREFERENCES OF
               SERIES C CONVERTIBLE PARTICIPATING PREFERRED STOCK

     Pursuant to the powers expressly granted to the Board of Directors of
Fieldworks, Incorporated, a Minnesota corporation (the "Company"), by the
provisions of the Articles of Incorporation of the Company and Chapter 302A of
the Minnesota Business Corporation Act, the Board of Directors of the Company
duly established by written action of the Board of Directors a series of shares
consisting of 500,000 shares, with the designation of the series and the
relative rights and preferences of the series as follows:

     1.   Designation.  The designation of the series of shares is Series C
          -----------
Convertible Participating Preferred Stock (the "Series C Shares") and the number
of shares of such series is 500,000.

     2.   Dividends.  Dividends shall be payable on the Series C Shares out of
          ---------
funds legally available for the declaration of dividends only if and when
declared by the Board of Directors. In no event shall any dividend be paid or
declared, nor shall any distribution be made, on the Common Stock, unless the
holders of the Series C Shares shall have consented thereto and shall
participate in such dividend on a pro rata basis with the holders of Common
Stock, counting the Series C Shares on an as-if-converted basis.

     3.   Liquidation Preference. In the event of any liquidation, the holders
          ----------------------
of the Series C Shares then outstanding shall be entitled to receive out of the
assets of the Company, after distribution of all amounts due the holders of the
Company's Series B Convertible Participating Preferred Stock ("Series B
Preferred Stock"), but prior and in preference to any distribution of any of the
assets or surplus funds of the Company to the holders of the Common Stock or any
other class of shares of preferred stock of the Company ranking junior to the
Series C Shares with respect to payments upon Liquidation (such preferred stock
hereinafter called "Junior Liquidation Stock"), and junior to any such
distribution to the holders of any class of shares of the Company ranking senior
to the Series C Shares in such respect, an amount equal to $2.00 per share plus
any accrued and unpaid dividends thereon for each Series C Share (the "preferred
amount"). Following any distribution of assets or surplus funds of the Company
to the holders of any outstanding series of Junior Liquidation Stock, the
remainder of any such assets or, surplus funds shall be

                                      -1-
<PAGE>

distributed to the holders of the Common Stock and any other series of preferred
stock entitled to participate in distributions of assets or surplus funds upon
liquidation until each holder shall have received an amount per share equal to
the preferred amount. Thereafter, any remaining assets or funds shall be
distributed pro rata to the holders of the Common Stock, the holders of any
other series of preferred stock having a right to participate, and the holders
of the Series C Preferred Stock, counting Series C Shares on an as-if-converted
basis. If upon the occurrence of any Liquidation, the assets and funds of the
Company available for the distribution to its shareholders shall be insufficient
to pay the holders of the Series C Shares the full preferred amount to which
they shall be entitled, the holders of the Series C Shares shall share ratably
in any distribution of such assets and surplus funds available to the Series C
Shares in proportion to the Series C Shares held by them.

     4.   Voting Rights. Each holder of record of Series C Shares shall be
          -------------
entitled to notice of and to attend all meetings of the shareholders of the
Company and shall be entitled at each such meeting to a number of votes for each
Series C Share held equal to the number of shares of Common Stock into which
each share of Series C Shares is then convertible. Each holder of Common Stock
shall have one vote on all matters submitted to the shareholders for each share
of Common Stock standing in the name of such holder on the books of the Company.
Except as otherwise provided in this Section 4, and except as otherwise required
by agreement or law, the holders of the Series C Shares and the holders of
Common Stock of the Company shall vote as a single class on all matters
submitted to the shareholders.

     5.   Protective Provisions.  The Company shall not take any of the
          ---------------------
following actions without the prior affirmative written consent of the holders
of at least two-thirds (2/3) of the Series C Shares:

          (a) alter, change or amend (by merger or otherwise) any of the rights,
     preferences or privileges of the Series C Shares;

     transaction or (iii) otherwise discontinue or dispose of more than ten

     the Company, (iv) any member of the immediate family of any Person set
     forth in clauses (i), (ii) and (iii) above, or (v) any corporation,
     partnership, trust or other entity in which any Person set forth in clauses

     is a director, officer, trustee, partner or holder of more than five
     percent (5%) of the outstanding capital stock thereof.  For purposes of
     this Agreement, the members of the "immediate family" of any Person shall
     consist of the spouse, parents, children, siblings, mothers- and fathers-
     in-law, sons- and daughters-in-law, and brothers- and sisters-in-law of
     such Person.

     6.   Conversion Rights.
          -----------------

          (a) At Option of Holders.  Holders of Series C Shares may, at their
              --------------------
option, upon surrender of the certificates therefor, convert any or all of their
Series C Shares into fully paid and nonassessable shares of Common Stock at any
time. The right of holders of Series C Shares to convert their shares shall be
exercised by surrendering for such purpose to the Company or any transfer agent
for the Series C Shares, and at such other office or offices, if any, as the
Board of Directors may designate, certificates representing the Series C Shares
to be converted, duly endorsed in blank or accompanied by proper instruments of
transfer. Upon the surrender of certificates representing the Series C Shares to
be converted, the person converting such shares shall be deemed to be the holder
of record of the Common Stock (and such other securities and property as the
holders of Series C Shares may be entitled to upon the conversion thereof, as
hereinafter provided) issuable upon such conversion, and all rights with respect
to the Series C Shares surrendered shall forthwith terminate except the right to
receive the Common Stock or other securities, cash or other assets receivable
upon such conversion as herein provided.

          (b) Conversion Rate/Conversion Price.  In addition to the adjustments
              --------------------------------
required by Section 6(e), 6(f) and 6(g), the conversion of Series C Shares into
Common Stock shall be governed by the following: Series C Shares shall be
convertible into that number of fully paid and nonassessable shares of Common
Stock (calculated as to each

                                      -5-
<PAGE>

conversion to the nearest 1/100th of a share) as shall be determined by
multiplying the "Conversion Rate," determined as hereinafter provided, in effect
at the time of conversion by the product of (i) the number of shares of Series C
Shares to be converted and (ii) the "Initial Conversion Price" applicable to the
shares of Series C Shares being converted (as hereinafter defined) and dividing
the product of such multiplication by the "Conversion Price" applicable to the
Series C Shares being converted, determined as hereinafter provided, in effect
at the time of conversion and making any adjustments required by Section 6(e)
hereof. The Conversion Rate shall initially be one and shall be adjusted from
time to time as provided in Section 6(e) (such conversion rate, as so adjusted
from time to time, being referred to herein as the "Conversion Rate"). The
"Initial Conversion Price" for the Series C Shares shall be the price per Series
C Share paid to the Company upon the issuance thereof. The conversion price for
Series C Shares shall initially be equal to the Initial Conversion Price and
shall be adjusted from time to time as provided in Sections 6(f) and (g) (the
conversion price for Series C Shares, as so adjusted from time to time, being
herein referred to as the "Conversion Price" applicable to such Series C
Shares).

          (c) Reservation of Shares.  A number of shares of authorized but
              ---------------------
unissued Common Stock of the Company sufficient to provide for the conversion of
all of the Series C Shares outstanding upon the basis herein provided
("Conversion Common Stock") shall at all times be reserved by the Company, free
from preemptive rights, for such conversion. If the Company shall issue any
securities or make any change in its capital structure that would change the
number of shares of Common Stock into which each Series C Share shall be
convertible as herein provided, the Company shall at the same time also make
proper provision so that thereafter there shall be a sufficient number of
additional shares of capital stock authorized and reserved, free from preemptive
rights, for conversion of the outstanding Series C Shares on the new basis. The
Company shall comply with all securities laws regulating the offer and delivery
of shares of Common Stock upon conversion of Series C Shares and shall list such
shares on any national securities exchange on which the Common Stock is listed
or have such shares admitted for quotation on the Nasdaq National or Small Cap
Market if the Common Stock is admitted for quotation thereon.

          (d) Fractional Shares.  No fractional shares of Common Stock shall be
              -----------------
issued upon the conversion of Series C Shares but, in lieu of any fraction of a
share of Common Stock that would otherwise be issuable in respect of the
aggregate number of such shares surrendered for conversion at one time by the
same holder, the Company shall pay in cash an amount equal to the product of (a)
the "Closing Price" (as defined in the next sentence) of a share of Common Stock
on the last trading day before the relevant conversion date and (b) such
fraction of a share. The "Closing Price" for each day shall be the last reported
sale price regular way or, in case no sale takes place on such day, the average
of the closing bid and asked prices regular way on such day, in either case as
reported on the New York Stock Exchange Composite Tape, or, if the Common Stock
is not listed or admitted to trading on such Exchange, on the principal national
securities exchange on which the

                                      -6-
<PAGE>

Common Stock is listed or admitted to trading, or, if the Common Stock is not
listed or admitted to trading on any national securities exchange, on the Nasdaq
National or Small Cap Market, or, if the Common Stock is not admitted for
quotation on the Nasdaq National or Small Cap Market, the average of the high
bid and low asked prices on such day as recorded by the National Association of
Securities Dealers, Inc. through Nasdaq, or, if the National Association of
Securities Dealers, Inc. through Nasdaq shall not have reported any bid and
asked prices for the Common Stock on such day, the average of the bid and asked
prices for such day as furnished by any New York Stock Exchange member firm
selected from time to time by the Company for such purpose, or, if no such bid
and asked prices can be obtained from any such firm, the fair market value of
one share of the Common Stock on such day as determined in good faith by the
Board of Directors of the Company.

          (e) Conversion Rate Adjustments.  Subject to Section 6(g) hereof, if
              ---------------------------
the Company shall (A) subdivide its outstanding Common Stock into a greater
number of shares, (B) combine the shares of its outstanding Common Stock into a
smaller number of shares or (C) declare a dividend upon its shares of Common
Stock payable in shares of Common Stock, then in each such case the Conversion
Rate in effect immediately prior thereto shall be proportionately adjusted so
that the holder of any shares of any Series C Shares thereafter surrendered for
conversion shall be entitled to receive, to the extent permitted by applicable
law, the number and kind of shares of capital stock of the Company that such
holder would have owned or have been entitled to receive after the happening of
such event had such Series C Shares been converted immediately prior to the
record date for such event (or if no record date is established in connection
with such event, the effective date for such action). An adjustment pursuant to
this Section 6(e) shall become effective immediately after the record date in
the case of a stock dividend or distribution, or immediately after the effective
date in the case of a subdivision, combination or reclassification.

          (f) Initial, One-Time Conversion Price Adjustment.  The Company
              ---------------------------------------------
contemplates a registered offering of rights to purchase common stock to its
shareholders.  If the purchase price of such offering is less than $2.00 per
share, the Conversion Price shall be adjusted to such purchase price.  If the
Company abandons, or shall not have completed such registered offering to its
existing shareholders of rights to purchase Common Stock resulting in gross
proceeds equal to or exceeding $5,000,000 on or before June 30, 2000, the
Conversion Price shall be reduced to One Dollar ($1.00) per share, effective as
of March 31, 2000, and any transactions subsequent to March 31, 2000 shall, for
purposes of Section 6(g), be evaluated using that adjusted Conversion Price.

          (g) Continuing Conversion Price Adjustments. With respect to Series C
              ---------------------------------------
Shares, if and whenever the Company shall issue or sell any shares of its Common
Stock or any securities convertible into or exercisable or exchangeable for
shares of Common Stock ("Convertible Securities") for a consideration per share
(in the case of the sale of any Convertible Securities, the amount, if any,
payable for such Convertible Security and upon

                                      -7-
<PAGE>

the exercise or conversion thereof (and/or upon the exercise or conversion of
the securities receivable upon such exercise or conversion) for each share of
Common Stock receivable thereby shall be included in determining such
consideration per share) less than the Conversion Price applicable to the Series
C Shares, in effect immediately prior to the time of such issuance or sale,
then, forthwith upon such issuance or sale, such higher Conversion Price(s) for
the Series C Shares shall be reduced to a price (calculated to the nearest tenth
of a cent) determined by dividing (x) an amount equal to the sum of (A) the
number of shares of Common Stock outstanding immediately prior to such issuance
or sale multiplied by such higher Conversion Price plus (B) the aggregate
                                                   ----
consideration, if any, received or receivable by the Company for the share of
Common Stock issued or issuable upon the exercise of any issued Convertible
Security (and/or upon the exercise or conversion of the security receivable upon
such exercise or conversion), by (y) an amount equal to the sum of (A) the
number of shares of Common Stock outstanding immediately prior to such issuance
or sale plus (B) the number of shares of Common Stock thus issued or sold or
        ----
receivable upon the exercise or conversion of the Convertible Securities (or the
securities receivable upon the exercise or conversion of such Securities). If
any Convertible Securities taken into account in any such adjustment of a
Conversion Price subsequently expire without exercise, such Conversion Price
shall be recomputed to eliminate the effect of such expired Convertible
Securities. However, no adjustment pursuant to this Section 6(g) shall be
required upon the issuance of shares of Common Stock upon conversion of any
shares of preferred stock, including the Series C Shares, outstanding prior to
such issuance or sale or upon the exercise of options available under the 1996
Directors Stock Option Plan or the 1999 Long-term Incentive Plan of the Company
as in effect prior to November 1, 1999.

          (h) Consolidations, Mergers, Sales of Assets, Reclassifications and
              ---------------------------------------------------------------
Certain Dividends.  In case of any (A) consolidation or merger of the Company
- -----------------
with any other company (other than the merger of a subsidiary of the Company
into the Company in a transaction in which the Company is the surviving
corporation and the outstanding shares of capital stock of the Company are not
exchanged for or converted into any other securities, cash or other property),
(B) sale or transfer of all or substantially all of the assets of the Company
for cash, securities or other property, (C) any share exchange pursuant to which
all of the outstanding shares of Common Stock are converted into other
securities or property, or (D) issuance of any shares of the Company's capital
stock in connection with a reclassification of the Common Stock, the Company
shall, prior to or at the time of such transaction, make appropriate provision
or cause appropriate provision to be made so that the holders of each Series C
Share then outstanding shall have the right thereafter to receive the kind and
amount of shares of stock and other securities and property receivable upon such
consolidation, merger, sale, transfer, share exchange or reclassification by a
holder of the number of shares of Common Stock into which such Series C Shares
could have been converted immediately prior to the effective date of such
consolidation, merger, sale, transfer, share exchange or reclassification.  If
in connection with any such consolidation, merger, sale, transfer, share
exchange or reclassification, each holder of Common Stock is

                                      -8-
<PAGE>

entitled to elect to receive either securities, cash or other assets upon
completion of such transaction, the Company shall provide or cause to be
provided to each holder of Series C Shares the right to elect the securities,
cash or other assets into which the Series C Shares held by such holder shall be
convertible after completion of any such transaction on the same terms and
subject to the same conditions applicable to holders of the Common Stock
(including, without limitation, notice of the right to elect, limitations on the
period in which such election shall be made and the effect of failing to
exercise the election).

          (i) Rounding.  All calculations hereunder, unless otherwise specified,
              --------
shall be made to the nearest cent or to the nearest 1/100th of a share, as the
case may be.

          (j) Notices.  Whenever the Conversion Rate or a Conversion Price is
              -------
adjusted as herein provided, the Company shall give prompt notice by mail to the
holders of the outstanding Series C Shares of such adjustment, which notice
shall set forth the adjustment and the new Conversion Rate or Conversion Price.
Notwithstanding the foregoing, failure by the Company to give such notice or a
defect in such notice shall not affect the binding nature of such corporate
action of the Company.

          (k) Common Stock Defined.  As used herein, the term "Common Stock"
              --------------------
shall mean and include the presently authorized Common Stock of the Company and
shall also include any capital stock of any class of the Company (other than the
Series C Shares) hereafter authorized which shall have the right to vote on all
matters submitted to the shareholders of the Company and shall not be limited to
a fixed sum or percentage in respect of the rights of the holders thereof to
participate in dividends or in the distribution of assets upon the occurrence of
any Liquidation Event of the Company.

     7.   Preemptive Rights.  If Company offers to sell its common stock,
          -----------------
securities convertible into common stock, or any other debt (excluding debt
securities issued to banks or other financial institutions) or equity securities
other than the issuance of options or shares to employees, directors and
consultants which have been approved by the directors elected by the Series B
Preferred Stock (the "Additional Securities") it will first offer to the holders
of the Series C Shares, or, if applicable, Conversion Common Stock the right to
purchase a portion of the Additional Securities such that such holders'
aggregate percentage ownership of the Company on a fully diluted basis
("Purchasers' Percentage") will be unchanged. The offer shall set forth the
number of shares to be sold, the price, and material terms and conditions.

The right of the holders to purchase in the aggregate Additional Securities up
to but not more than the Purchaser's Percentage may be exercised as follows:

          (a) the Company shall provide each holder with written notice of the
number of securities to be issued and the cash price therefor;

                                      -9-
<PAGE>

          (b) each holder shall have the right to purchase that percentage of
such securities equal to the ratio that the number of shares of Conversion
Common Stock held by such holder bears to the total number of shares of
Conversion Common Stock held by all holders;

          (c) second, if not all holders elect to purchase their pro rata share,
then as to the excess of the amount of Purchaser's Percentage over the shares
taken by holders electing to purchase their pro rata part (such excess to be
referred to as the "Unsubscribed Shares"), the holders who do so elect shall be
offered the right to acquire pro rata among themselves based on their holdings
of Conversion Common Stock; and

          (d) if after such offer, any of the Unsubscribed Shares remain unsold,
as to such unsold Unsubscribed Shares, as the holders who agreed to purchase
their pro rata part of the Unsubscribed Shares may agree, all within thirty (30)
days of notice by the Company of such proposed issuance.

          The Company may, within thirty (30) days, sell the remaining
securities not to be purchased by the holders to third parties on the terms and
conditions set forth in the offer delivered to holders, and the holders shall be
required to deliver the consideration to Company for the securities being
purchased by the holders at the same time such third parties are required to
deliver their consideration to Company.

          Notwithstanding anything in this Section 7 to the contrary, the
holders' rights under this Section 7 shall not apply to (i) the securities of
the Company outstanding immediately prior to the issuance of the initial Series
C Shares; (ii) shares of common stock issued in connection with any stock split,
stock dividends or recapitalization of Company or upon conversion of the Series
C Shares; (iv) any borrowings, direct or indirect from financial institutions by
the Company, whether or not presently authorized, evidenced by any type of debt
instrument with no equity features; (v) securities issued pursuant to an
effective registration statement filed with the SEC in connection with a
registered public offering; (vi) equity securities issued to a financial
institution in connection with any lease financing or debt financing of the
Company approved by a two-thirds (2/3) vote of the Board of Directors; or (vii)
any transaction in which all directors of the Company elect for this Section 7
not to apply.

         On the basis of the foregoing and of our examination of such other
questions of law and fact as we deem relevant under the circumstances, and in
reliance thereon, and subject to the limitations, qualifications, presumptions
and exceptions set forth herein, we are of the opinion that:

         1. The Company is duly incorporated, validly existing and in good
standing under the laws of the State of Minnesota with corporate power and
authority to conduct its business as it is presently conducted, to own and lease
its properties and assets and to execute and deliver the Transaction Documents

corporation and is in good standing in each jurisdiction in which (i) such
qualification is necessary under applicable law as a result of its conduct of
business and (ii) the failure to be so qualified would have a Material Adverse
Effect.

         3. Each of the Transaction Documents has been duly authorized, executed
and delivered by the Company and is a valid and binding obligation of Company,
enforceable against the Company in accordance with its terms.

         4. The Company has taken action to reserve 500,000 shares of Common
Stock for future issuance in connection with the exercise of the Series C

in Article III in the Agreement are true and correct, the offer and sale of the
Series C Preferred Stock to Purchaser pursuant to the terms of the Agreement are
exempt from the registration requirements of the Securities Act of 1933 (the
"Securities Act"). Assuming the representations and warranties made by Purchaser
in Article III in the Agreement are true and correct, the issuance to Purchaser
of the Conversion Shares in accordance with the terms of the Agreement will be
exempt from such registration and qualification requirements.

         5. Neither the execution and delivery by the Company of the Transaction
Documents nor the performance of its obligations thereunder will (a) result in
the violation of (i) any federal or Minnesota statute or regulation applicable
to the Company or (ii) any order or decree known to us of any court or
governmental authority binding upon the Company or its property, (b) conflict
with the Company's Articles of Incorporation or Bylaws or (c) result in a

and delivery or the performance of the Transaction Documents to which it is a
party.

         7. The authorized capital stock of the Company consists of 30,000,000

which 8,894,426 shares are issued and outstanding, and 5,000,000 shares of
preferred stock, $.001 par value, of which 4,250,000 shares have been designated

Stock (the "Series C Stock").

         8. The Series C Stock has been validly authorized, and the delivery by
the Company to Purchaser at Closing of the certificates representing the Series
C Stock, upon payment in accordance with the Agreement, conveys and transfers to
Purchaser, good, complete and marketable title to all Series C Stock of the

         (b) Our opinion as to good standing of the Company set forth in
paragraph 1 above is based solely upon a certificate of good standing from the

interpretation or enforcement of such agreement and our opinion in paragraph 3
above is based on the assumption, for purposes of this opinion, that the
internal laws of the State of Minnesota and the federal laws of the United
States of America would govern the provisions of the Agreement and the
transactions contemplated thereby.

         We express no opinion regarding the accuracy of any financial
representations in the Transaction Documents or the financial status of the

          (a) Required Threshold.

          Any Eligible Holder owning at least One Hundred Thousand (100,000)
     Common Stock Equivalents (as such number may be equitably adjusted from
     time to time to reflect any stock split, stock dividend, recapitalization,
     reclassification, consolidation or the like) may request (such Person, the
     "Initiating Holder") that the Company file a Registration Statement under
     the Securities Act on an appropriate form with respect to at least fifty
     percent (50%) of the Registrable Securities owned by such Initiating Holder
     (which form shall be available for the sale of the Registrable Securities
     in accordance with the intended method or methods of distribution thereof
     and shall include all financial statements required by the SEC to be filed
     herewith) covering the shares of Registrable Securities that are the
     subject of such request and the Company shall file such a Registration
     Statement.

          (b) Number of Demand Registrations.

          The Company shall be obligated to prepare, file and cause to become
     effective pursuant to this Section 2 only one (1) Registration Statement in
     the aggregate pursuant to Section 2(a) above for the Eligible Holders;
     provided, however, that a Registration Statement shall not be counted as
     the Demand Registration hereunder unless it becomes effective and is
     maintained effective in accordance with the requirements specified in
     Section 6(a); provided, further, that if there is an underwriter's cutback
     pursuant to Section 2(e) with respect to the request for registration
     initiated by an Eligible Holder, such requested registration shall not be
     deemed to be the Demand Registration.


                                       C-2
<PAGE>

          (c) Deferral by Company.

          Notwithstanding anything in this Section 2 to the contrary, the
     Company shall not be obligated to prepare, file and cause to become
     effective pursuant to this Section 2 a Registration Statement if within
     five (5) days of receipt of a request for a Demand Registration the Company
     furnishes to the Initiating Holder a certificate signed by the Chief
     Executive Officer of the Company that, in the good faith judgment of the
     Board of Directors, it would be detrimental in any material respect to the
     Company and its shareholders for the Company to comply with the Demand
     Registration, and it is therefore essential to defer the filing of the
     Registration Statement relating thereto. Any such deferral shall be for a
     period of not more than six (6) months after the Company's receipt of the
     Initiating Holder's written request for registration pursuant to this
     Section 2; provided, however, that the Company may not exercise this right
     more than once with respect to the Demand Registration and that any
     requested registration deferred, and not ultimately effected, by the
     Company pursuant to the provisions of this Section 2(c) shall thereafter
     not be deemed to be the Demand Registration for purposes of the Section
     2(a) above.

          (d) Participation.

          The Company shall promptly give written notice to all other Eligible
     Holders upon receipt of a request for a Demand Registration pursuant to
     Section 2(a) above. Such other Eligible Holders may, by written notice to
     the Company and the Initiating Holder, within thirty (30) business days of
     the Company's notice, elect to join in a request for a Demand Registration
     pursuant to Section 2(a) above, with respect to any number of shares of
     Registrable Securities owned by such Eligible Holder. The Registrable
     Securities of the other Eligible Holders being offered in such Demand
     Registration shall be treated pari passu with the Registrable Securities
     being offered by the Initiating Holder for all purposes including
     "underwriter's cutbacks" under subsection (e) of this Section and any such
     request by an Eligible Holder shall not be treated as either a request by
     such Eligible Holder for a Piggyback Registration under Section 3 or as a
     request by such Eligible Holder for a Demand Registration under this
     Section 2. The Company shall include in such Demand Registration such
     shares of Registrable Securities for which it has received written requests
     to register such shares within thirty (30) days after such written notice
     has been given, provided that all the Registrable Securities for which the
     Initiating Holder and the other Eligible Holders have requested
     registration shall be covered by such registration statement before any
     other securities are included.

          In addition, the Company shall promptly give written notice to all
     eligible Holders upon receipt of a request for a demand registration by any
     Person (such Person, the "Initiating Person") pursuant to any other
     registration rights agreement with the Company (whether such other
     registration rights agreement is entered into before or after the date
     hereof).


                                       C-3
<PAGE>

     Each Eligible Holder may, by written notice to the Company, within thirty
     (30) business days of the Company's notice, elect to request a Demand
     Registration pursuant to Section 2(a) above, with respect to any shares of
     Registrable Securities owned by such Eligible Holder. The Registrable
     Securities of the Eligible Holders being offered in such Demand
     Registration shall be treated pari passu with the registrable securities
     being offered by the Initiating Person (unless such Initiating Person is a
     holder of Series B Preferred Stock, Warrants issued to Industrial Works
     Holding Co., LLC, or Common Stock obtained on exercise or conversion
     thereof, in which case the securities proposed to be registered by such
     Initiating Person should be given priority) for all purposes including
     "underwriter's cutbacks" and any such request by an Eligible Holder shall
     not be treated as either a request by such Eligible Holder for a Piggyback
     Registration under Section 3 or as a request by such Eligible Holder for a
     Demand Registration under this Section 2. The Company shall include in such
     demand registration such shares of Registrable Securities for which it has
     received written requests to register such shares within thirty (30) days
     after such written notice has been given, provided that all the Registrable
     Securities for which the Initiating Person and the Eligible Holders have
     requested registration shall be covered by such registration statement
     before any other securities are included.

          (e) Underwriter's Cutback.

          If the public offering of Registrable Securities is to be underwritten
     and, in the good faith judgment of the managing underwriter, the inclusion
     of all the Registrable Securities requested to be registered hereunder
     would interfere with the successful marketing of such shares of Registrable
     Securities, the number of shares of Registrable Securities to be included
     shall be reduced and the number of shares to be included in the
     underwriting or registration shall be allocated first among the Eligible
     Holders pro rata upon the basis of the number of shares of Registrable
     Securities sought to be offered by the Eligible Holders pursuant to such
     Demand Registration and any remainder shall be allocated among the Company
     and the other persons entitled to incidental registrations pro rata upon
     the basis of the number of shares of Registrable Securities sought to be
     registered thereby. If a person who has requested inclusion in such Demand
     Registration does not agree to the terms of any such underwriting, such
     person shall be excluded therefrom by written notice from the Company, the
     underwriter or the Initiating Holder, and the securities owned by such
     person(s) shall be withdrawn from registration (the "Withdrawn
     Securities").

          If there are any Withdrawn Securities as a result of an Underwriter's
     Cutback, then the Company shall offer to those persons who have retained
     rights to include securities in the Demand Registration the right to
     include additional securities in the registration in an aggregate amount
     equal to the number of Withdrawn Securities that would have been included
     in the Demand Registration after giving effect to the Underwriter's Cutback
     had such securities not been withdrawn, with such shares to be allocated
     among such persons in accordance with the allocation of rights set forth in
     this paragraph (e).

                                       C-4

          (f) Managing Underwriter.

          The managing underwriter or underwriters of any Underwritten Offering
     covered by a Demand Registration shall be selected by a majority in
     interest of the Eligible Holders participating in such Underwritten
     Offering and shall be reasonably acceptable to the Company. The right of
     any other Holders joining in a request for registration as provided in
     Section 2(d) above to registration pursuant to this Section 2 shall be
     conditioned upon such Holder's participation in such underwriting and the
     inclusion of such Holder's Registrable Securities in the underwriting on
     the same terms as those of the Initiating Holder (unless otherwise mutually
     agreed by a majority in interest of the Eligible Holders participating in
     such registration and such Holder with respect to such participation and
     inclusion).

     3. Piggyback Registrations

          (a) Participation.

          Each time the Company decides to file a Registration Statement under
     the Securities Act (other than registrations on Forms S-4 or S-8 or any
     successor form thereto, and other than a Demand Registration or a demand
     registration by an Initiating Person) covering the offer and sale by it or
     any of its security holders of any of its securities for money, the Company
     shall give written notice thereof to all Eligible Holders. The Company
     shall include in such Registration Statement such shares of Registrable
     Securities for which it has received a written request from any Eligible
     Holder to register such shares within twenty (20) days after such written
     notice has been given. If the Registration Statement is to cover an
     Underwritten Offering, such Registrable Securities shall be included in the
     underwriting on the same terms and conditions as the securities otherwise
     being sold through the underwriters.

          (b) Underwriter's Cutback.

          Subject to the requirements of Section 12 hereof, if in the good faith
     judgment of the managing underwriter of such offering the inclusion of all
     of the shares of Registrable Securities and any other Common Stock
     requested to be registered would interfere with the successful marketing of
     such shares, then the number of shares of Registrable Securities and other
     Common Stock to be included in the offering shall be reduced, with the
     participation in such offering to be in the following order of priority:
     (1) first, the shares of Common Stock which the Company proposes to sell
     for its own account, (2) second, the shares of holders exercising rights
     given to holders of Series B Preferred Stock or holders of Warrants issued
     to Industrial-Works Holding Co., LLC, (3) third, the shares of Registrable
     Securities of all Eligible Holders requested to be included, and (4)
     fourth, any other shares of Common Stock requested to be included. Any
     necessary allocation among the Holders of shares within each of the
     foregoing groups shall be pro rata among such Holders requesting such
     registration based

                                       C-5
<PAGE>

     upon the number of shares of Common Stock and Registrable Securities owned
     by such Holders.

          (c) Company Control.

          The Company may decline to file a Registration Statement after giving
     notice to Eligible Holders pursuant to Section 3(a) above, or withdraw a
     Registration Statement after filing and after such notice, but prior to the
     effectiveness thereof; provided that the Company shall promptly notify each
     Eligible Holder in writing of any such action and provided further that the
     Company shall bear all expenses incurred by each Eligible Holder or
     otherwise in connection with such withdrawn Registration Statement.

     4. Registration on Form S-3

          (a) Right to Request Registrations on Form S-3.

          At any time the Company is qualified for the use of Form S-3, in
     addition to the rights contained in the foregoing provisions of this
     Agreement, the Eligible Holders shall have the right to request
     registrations on Form S-3 or any comparable or successor form. Each such
     request shall be in writing and shall state the anticipated number of
     shares of Registrable Securities to be disposed of and the anticipated
     gross proceeds of such shares, and the intended methods of disposition of
     such shares by such Eligible Holder or Eligible Holders, including whether
     such resales are to be made on a delayed or continuous basis pursuant to
     Rule 415. The Company shall not be obligated to effect any registration
     pursuant to this Section 4 if (i) the Eligible Holders propose to sell
     Registrable Securities representing less than fifteen percent (15% ) of the
     shares of the Registrable Securities then held by all Eligible Holders or
     (ii) the circumstances described in Section 2(c) shall apply (but subject
     to the limitations set forth therein).

          (b) Application of Certain Provisions.

          If the registration is for an Underwritten Offering, the provisions of
     Sections 2(d) and 2(f) hereof shall also apply to such registration, except
     the Company may not include any shares for its own account.

     5. Hold-back Agreements

          (a) By Holders of Registrable Securities.

          Upon the written request of the managing underwriter of any
     Underwritten Offering of the Company's securities, a Holder of Registrable
     Securities shall not sell or

                                       C-6
<PAGE>

     otherwise dispose of any Registrable Securities (other than those included
     in such registration) without the prior written consent of such managing
     underwriter for a period (not to exceed thirty (30) days before the
     effective date and one hundred twenty (120) days thereafter) that such
     managing underwriter reasonably determines is necessary in order to effect
     the Underwritten Offering; provided that each of the officers and directors
     of the Company, and each Holder of more than one percent (1%) of the Common
     Stock of the Company, shall have entered into substantially similar
     holdback agreements with such managing underwriter covering at least the
     same period.

          (b) By the Company and Others.

          The Company agrees:

               (1) not to effect any public or private sale or distribution of
          any of its equity securities during the 30-day period prior to, and
          during the 120-day period after, the effective date of each
          Underwritten Offering made pursuant to a Demand Registration or a
          Piggyback Registration, if so requested in writing by the managing
          underwriter (except as part of such Underwritten Offering, pursuant to
          registrations on Forms S-4 or S-8 or any successor forms thereto), and

               (2) not to issue any Equity Securities other than for sale in a
          registered public offering unless each of the Persons to which such
          securities are issued has entered a written agreement binding on its
          transferees not to effect any public sale or distribution of such
          securities during such 130-day period, including without limitation a
          sale pursuant to Rule 144 under the Securities Act (except as part of
          such Underwritten Registration, if and to the extent permitted
          hereunder).

     6. Registration Procedures

     If and whenever the Company is required to register Registrable Securities
pursuant to this Agreement, the Company will use all commercially reasonable
efforts to effect such registration to permit the sale of such Registrable
Securities in accordance with the intended plan of distribution thereof and will
as expeditiously as practicable:

          (a) prepare and file with the SEC as soon as practicable a
     Registration Statement with respect to such Registrable Securities and use
     all commercially reasonable efforts to cause such Registration Statement to
     become effective and remain continuously effective until the date that is
     the earlier to occur of (i) the date six months from the date such
     Registration Statement was declared effective, and (ii) the date the last
     of the Registrable

                                       C-7
<PAGE>

     Securities covered by such Registration Statement have been sold, provided
     that before filing a Registration Statement or Prospectus or any amendments
     or supplements thereto, the Company shall furnish to Holders of Registrable
     Securities covered by such Registration Statement and the underwriters, if
     any, draft copies of all such documents proposed to be filed, which
     documents will be subject to the review of each Eligible Holder and such
     underwriters, and the Company shall not file any Registration Statement or
     amendment thereto or any Prospectus or any supplement thereto to which the
     Eligible Holders or the underwriters, if any, shall reasonably object;

          (b) prepare and file with the SEC such amendments and post-effective
     amendments to the Registration Statement, and such supplements to the
     Prospectus, as may be requested by any underwriter of Registrable
     Securities or as may be required by the rules, regulations or instructions
     applicable to the registration form used by the Company or by the
     Securities Act or rules and regulations thereunder to keep the Registration
     Statement effective until all Registrable Securities covered by such
     Registration Statement are sold in accordance with the intended plan of
     distribution set forth in such Registration Statement or supplement to the
     Prospectus;

          (c) promptly notify the selling Holders of Registrable Securities and
     the managing underwriter, if any, and (if requested by any such Person)
     confirm such advice in writing,

               (1) when the Prospectus or any supplement or post-effective
          amendment has been filed, and, with respect to the Registration
          Statement or any post-effective amendment, when the same has become
          effective,

               (2) of any request by the SEC for amendments or supplements to
          the Registration Statement or the Prospectus or for additional
          information,

               (3) of the issuance by the SEC of any stop order suspending the
          effectiveness of the Registration Statement or the initiation of any
          proceedings for that purpose,

               (4) if at any time the representations and warranties of the
          Company contemplated by clause (1) of paragraph (o) below cease to be
          accurate in all material respects,

               (5) of the receipt by the Company of any notification with
          respect to the suspension of the qualification of the Registrable
          Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose, and

                                       C-8
<PAGE>

               (6) of the existence of any fact which results in the
          Registration Statement, the Prospectus or any document incorporated
          therein by reference containing a misstatement;

          (d) make all commercially reasonable efforts to obtain the withdrawal
     of any order suspending the effectiveness of the Registration Statement at
     the earliest practicable time;

          (e) unless the Company objects in writing on reasonable grounds, if
     requested by the managing underwriter or any Eligible Holder holding more
     than twenty-five percent (25%) of the Registrable Securities then
     outstanding, as promptly as practicable incorporate in a supplement or
     post-effective amendment such information as the managing underwriter and
     such Eligible Holder agree should be included therein relating to the sale
     of the Registrable Securities, including, without limitation, information
     with respect to the number of shares of Registrable Securities being sold
     to underwriters, the purchase price being paid therefor by such
     underwriters and with respect to any other terms of the Underwritten
     Offering of the Registrable Securities to be sold in such offering; and
     make all required filings of such supplement or post-effective amendment as
     soon as notified of the matters to be incorporated in such supplement or
     post-effective amendment;

          (f) only with respect to Demand Registrations, promptly prior to the
     filing of any document which is to be incorporated by reference into the
     Registration Statement or the Prospectus (after initial filing of the
     Registration Statement) provide copies of such document to counsel to each
     of the Eligible Holders and to the managing underwriter, if any, and make
     the Company's representatives available for discussion of such document and
     make such changes in such document prior to the filing thereof as counsel
     for each Eligible Holder or underwriters may reasonably request;

          (g) furnish to each selling Holder of Registrable Securities and the
     managing underwriter, without charge, at least one signed copy of the
     Registration Statement and any post-effective amendments thereto, including
     financial statements and schedules, all documents incorporated therein by
     reference and all exhibits (including those incorporated by reference);

          (h) deliver to each Eligible Holder and the underwriters, if any,
     without charge, as many copies of each Prospectus (and each preliminary
     prospectus) as such Persons may reasonably request (the Company hereby
     consenting to the use of each such Prospectus (or preliminary prospectus)
     by each of the selling Holders of Registrable Securities and the
     underwriters, if any, in connection with the offering and sale of the
     Registrable Securities covered by such Prospectus (or preliminary
     prospectus));

                                       C-9
<PAGE>

          (i) prior to any public offering of Registrable Securities, use all
     commercially reasonable efforts to register or qualify or cooperate with
     the selling Holders of Registrable Securities, the underwriters, if any,
     and their respective counsel in connection with the registration or
     qualification of such Registrable Securities for offer and sale under the
     securities or blue sky laws of such jurisdictions as such underwriters may
     designate in writing and do anything else necessary or advisable to enable
     from a legal perspective the disposition in such jurisdictions of the
     Registrable Securities covered by the Registration Statement; provided that
     the Company shall not be required to qualify generally to do business in
     any jurisdiction where it is not then so qualified or to take any action
     which would subject it to general service of process in any such
     jurisdiction where it is not then so subject;

          (j) cooperate with the selling Holders of Registrable Securities and
     the managing underwriter, if any, to facilitate the timely preparation and
     delivery of certificates not bearing any restrictive legends representing
     the Registrable Securities to be sold and cause such Registrable Securities

   Re: Management Services Agreement

Gentlemen:

   Fieldworks, Incorporated ("Fieldworks") hereby engages you to perform
advisory and consulting services to Fieldworks for a period of one-year
commencing upon the date of this Agreement.

  1. Scope of Primary Services. The primary services to be provided by you
     consist of active and continuing support to FieldWorks' management in
     identifying, developing and executing all major strategic, acquisition,
     operational and financial opportunities for FieldWorks.

    a. During the initial three months of this Agreement, you will arrange
       for Robert Forbes to provide these primary services for at least 16
       days per month, unless you and we agree to a different schedule.
       During this initial three-month period, you agree that these services
       will be provided on-site at our facilities, off-site for meetings
       with existing or prospective vendors or customers, or at another
       mutually agreed location.

    b. Following the initial three months of this Agreement, you shall
       determine, in consultation with our board of directors, which of your
       personnel shall be assigned to provide these primary services.
       Further, we agree that, following the initial three month period of
       this Agreement, such services are not expected to consume more than
       five man-days per month and such services may be provided from such
       locations as you determine.

  2. Compensation for Primary Services. For the primary services described
     above, we will pay you (a) $10,000 on the date hereof, (b) $10,000
     within 30 days after the date hereof, (c) $10,000 within 60 days after
     the date hereof, and (d) $200,000 simultaneously with the closing of the
     transactions contemplated by the Securities Purchase Agreement of even
     date herewith, between Industrial-Works Holding Corp., a Delaware
     corporation (the "Securities Purchase Agreement").

  3. Reimbursement of Expenses. We agree to reimburse or pay directly your
     reasonable expenses, including travel, hotel or boarding charges, meals
     and other items customarily reimbursed to outside advisors or
     consultants. Such expenses, if not paid directly by Fieldworks at your
     request, shall be paid to you within five business days of submission of
     an itemized invoice evidencing your payment of such expenses.

  4. Additional Services and Compensation. In addition to the primary
     services and related compensation described above, we agree that you
     will be entitled to additional compensation if, for example, at our
     request (a) any of your employees or representatives (in addition to
     Robert Forbes) provide substantial services to us during the initial
     three-month period of this Agreement, or (b) Robert Forbes or any other
     employees or representatives provide more than five man-days of services
     per month following the initial three-month period of this Agreement. If

     transaction, you shall be entitled to such additional compensation as
     shall be negotiated at the time such services are rendered.

     amounts have not previously been paid), (y) the indemnity provisions of
     paragraph 6 below shall survive plus (z) you shall be paid$100,000 if

     Company's shareholders to approve the transactions it contemplates,.

     carry directors' and officers' insurance in an amount not less than $5
     million to include you and your designated persons as additional

agreement to which this Addendum A is attached, Fieldworks, Incorporated
("Company") agrees to indemnify and hold harmless Glenmount, LLC ("Glenmount")
and each of its officers, directors, representatives, agents, employees and
controlling persons (within the meaning of the Securities Act of 1933, as
amended) against any losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) related to or arising out of this engagement,
and will reimburse Glenmount and each other person indemnified hereunder for
all legal and other expenses as incurred in connection with investigating or
defending any such loss, claim, damage, liability, action or proceeding whether
or not in connection with pending or threatened litigation in which Glenmount
or any of other person indemnified hereunder is a party; provided, however,
that the Company will not be liable in any such case (except cases arising out
of the use of information provided by any Company) for losses, claims, damages,
liabilities or expenses arising from the gross negligence or willful misconduct
of Glenmount or the party claiming a right to indemnification.

   In case any proceeding shall be instituted involving any person in respect
of whom indemnity may be sought, such person (the "Indemnified Party") shall
promptly notify the Company, and the Company, upon the request of the
Indemnified Party, shall retain counsel reasonably satisfactory to the
Indemnified Party to represent the Indemnified Party and any others the Company
may designate in such proceeding and shall pay as incurred the fees and
expenses of such counsel related to such proceedings. In any such proceeding,
any Indemnified Party shall have the right to retain its own counsel at its own
expense, except that the Company shall pay as incurred the fees and expenses of
counsel retained by the Indemnified Party in the event that (i) the Company and
the Indemnified Party shall have mutually agreed to the retention of such
counsel or, (ii) the named parties to any such proceeding (including any
impleaded parties) include the Company and the Indemnified Party and
representation of such parties by the same counsel would be inappropriate, in
the reasonable opinion of the Indemnified Party, due to actual or potential
differing interests between them.

   The Company shall not be liable for any settlement of any proceeding
effected without its written consent. In addition, the Company will not,
without the prior written consent of Glenmount, settle or compromise or consent
to the entry of any judgment in any pending or threatened claim, action, suit
or proceeding in respect of which indemnification may be sought hereunder
(whether or not Glenmount or any Indemnified Party is an actual or potential
party to such claim, action, suit or proceeding) unless such settlement,
compromise or consent includes an unconditional release of Glenmount and each
other Indemnified Party hereunder from all liability arising out of such claim,
action, suit or proceeding.

Dear David:

As you know, Glenmount, LLC ("Glenmount") has provided services to FieldWorks,
Incorporated ("FieldWorks") during the initial three-month period of the
Management Services Agreement, dated as of November 20, 1999 (the "Agreement"),
that exceed the scope and nature of the services contemplated by the monthly
and closing fees specified in the Agreement. In addition, Glenmount has arranged
for Industrial-Works Holding Co., LLC ("IWHC") to provide a commitment letter
to FieldWorks with respect to the purchase of up to 3,000,000 shares of
preferred stock.

This letter will confirm our mutual agreement to supplement the Agreement, as
set forth below, to compensate Glenmount for these additional services.

In consideration of the foregoing, FieldWorks hereby agrees (a) to promptly pay
Glenmount $30,000 as additional compensation for the initial three-month
period of the Agreement, (b) to extend the $10,000 per month fee to Glenmount
for each month during the balance of the term of the Agreement, and (c) to pay
an additional fee equal to 4% of the purchase price of any securities issued by
FieldWorks to IWHC (other than the 4,250,000 shares of Series B Convertible
Preferred Stock, the warrant and the 500,000 warrant shares issued pursuant to
the Stock Purchase Agreement dated as of November 20, 1999), payable on the date
any such securities are purchased by IWHC.

If the terms of this letter are acceptable, please sign below and return a copy
of this letter to us.

Sincerely,

Michael E. Johnson

              [LETTERHEAD OF INDUSTRIAL-WORKS HOLDING CO., LLC]


March 31, 2000

Fieldworks, Incorporated
7631 Anagram Drive
Eden Prairie, MN 55344
Attention: Mr. David Malmberg, Chairman

Ladies and Gentlemen:

We previously issued to you by a letter dated February 18, 2000 a commitment to
purchase up to $3,000,000 of additional Series B Preferred Stock of Fieldworks.
You have requested us to modify such commitment and to invest additional funds
at a date earlier than our previous commitment contemplated, and we are today
entering into a Stock Purchase Agreement providing for us to purchase 500,000
shares of a new Series C Preferred Stock at $2.00 per share. In the same
agreement, Fieldworks is committing to commence a registered offering to all
holders of its stock of rights to purchase common stock at $2.00 per share (the
"rights offering").

This letter is written to confirm the agreement of IWHC to purchase at least
1,000,000 shares in this rights offering, provided that other shareholders
purchase at least 1,500,000 shares, and provided the purchase price in the
rights offering is $2.00 per share, as presently contemplated. If the price is
changed with our consent, IWHC will purchase $2,000,000 in value provided other
holders purchase at least $3,000,000 in value. This commitment shall expire if
the rights offering is not completed by June 30, 2000 or if prior to the
completion of the rights offering the Fieldworks common stock ceases to be
admitted to trading (or if Fieldworks is given notice of a decision to cause
such a delisting) on the Nasdaq National Market System.

IWHC reserves the right to purchase its full allocation in the rights offering
(considering both its Series B Preferred Stock and the newly acquired Series C
Preferred) and to exercise its oversubscription privilege.

In consideration for IWHC's commitment in this letter, FieldWorks acknowledges
that the February 18, 2000 comittment letter is cancelled and replaced by this
commitment letter. IWHC shall retain the five-year warrant to purchase 100,000
shares of Common Stock of FieldWorks issued on the date of acceptance of the
February 18, 2000 commitment.
<PAGE>

As the holder of the Fieldworks Series B Preferred Stock, IWHC hereby consents
to the Stock Purchase Agreement dated March 31, 2000 and to the issuance of the
Series C Convertible Participating Preferred Stock and to all terms of such
Series C Preferred.

If the terms of this Commitment Letter are acceptable, please sign below and
return a copy of this letter to us.

Sincerely,

/s/ Michael E. Johnson
