                         About FieldWorks, Incorporated

     FieldWorks began as a company dedicated to the development and sale of
rugged mobile computing platforms. Over the past several years, we have evolved
our strategy to focus on designing and providing complete customer-specific
field technology solutions. We believe that our strongest opportunity for growth
and differentiation lies in integrating our hardware with our own and third
parties' open architecture software. The resulting computing solutions are
intended for use in service bay, test and measurement, and logistics management
applications in the trucking, public services, heavy equipment and
government/military industries worldwide. To produce these solutions, we combine
appropriate hardware, software and peripherals - in other words, we function as
a sophisticated systems supplier and integrator. We also offer customers a high
level of industry expertise in service and support. Our professional services
capabilities include consultation and/or management of solution
conceptualization, design, development, implementation and support.

     We have designed our computing platforms for demanding field environments.
All of our platforms meet military standards for shock, vibration, moisture and
temperature extremes. Features include daylight-readable color displays and a
pointing device that is impervious to dirt and can be used with a glove. Our
platforms also offer a high level of expandability. Expansion paths include
desktop-like ISA and PCI expansion slots, PC card slots, serial ports, universal
serial bus and custom modules. As a result, all platforms are flexible
"electronic toolboxes" that integrate an end-user's application-specific tools
and technologies into one custom, rugged mobile tool. Lastly, we have designed
our platforms with a modular system architecture that allows a user to upgrade
them to incorporate new central processing units, display technologies and
peripheral technologies, such as wireless communication. This contributes to a
long life span and reduces the customer's total cost of ownership.

     The market for our products and solutions consists of those businesses and
entities that are seeking effective mobile platforms for field personnel and
functions. We have focused on the following vertical markets:

     .    transportation/trucking companies, which require diagnostic service
          applications in a single PC-based tool with integrated software
          modules and hardware peripherals;

     .    utilities and telecommunications test crews, which require electronic
          toolboxes that can perform data acquisition, diagnostic,
          communications and analysis tasks to expedite installation, repair and
          troubleshooting;

     .    public safety personnel, who require mobile data terminals that link
          into central dispatch; and

     .    the military, which requires mobile units that are capable of
          withstanding battlefield conditions and are used chiefly for
          communication and field data acquisition purposes.

     Our goal is to be the worldwide leader in providing computing solutions for
demanding field environments. To accomplish this, we:

     .    mainly target the key vertical markets mentioned above and develop
          specialized product features and functions to address the special
          needs of those vertical markets;

     .    are working to position ourselves as a professional service and system
          integration company that offers unique market application expertise
          and customer support regarding the use of the technology we provide;

     .    are in the final stages of outsourcing work where value is not
          recognized and rewarded by our customers, in particular procurement
          and manufacturing related to our products; and

     .    are focused on reducing product cost through significant product re-
          design initiatives that incorporate embedded systems in the design of
          our products.

     FieldWorks was incorporated under the laws of the State of Minnesota in
October 1992. Our executive offices are located at 7631 Anagram Drive, Eden
Prairie, Minnesota 55344, and our telephone number is (612) 974-7000. Our

                                 RISK FACTORS

     Before investing in our common stock, you should be aware that there are
various risks, including those described below. Your investment in our common
stock will be subject to the risks inherent in our business. The value of your
investment may decline and could result in a loss of your entire investment. You
should carefully consider the following factors as well as the other information
contained in or incorporated by reference in this prospectus before deciding to
exercise your rights to buy our common stock.

                        Risks Related to Our Operations

We have a history of losses and expect to continue to generate losses in the
future

     As of January 2, 2000, we had an accumulated deficit of $19.8 million. We
have not achieved profitability and, as the result of computing solution
development and initiatives to reduce the cost of our products, we expect to
continue to incur net losses through at least 2000. We expect to continue to
incur significant operating expenses and, as a result, will need to generate
significant revenues to achieve profitability, which may not occur. Even if we
do achieve profitability, we may be unable to sustain or increase profitability
on a quarterly or annual basis in the future.

We cannot assure you that we will generate sufficient sales to allow us to
operate profitably

     The market for the kind of computing platforms and solutions we sell is
relatively new and limited. The rugged computing platforms that we use are both
heavier and more expensive than most consumer portable personal computers. Our
success will depend upon our ability to expand the professional services and
solutions we offer, penetrate our key vertical markets of
transportation/trucking, heavy equipment, public service and
government/military, and increase the market acceptance of our solutions and
products. We cannot assure you that our current or new products will gain
widespread acceptance or that we will generate sufficient sales to allow us to
operate profitably. We will in particular suffer adverse effects if the market
for the kind of computing solutions and products we sell does not expand.

Our ability to develop solutions around our rugged platforms will influence our
ability to compete in the marketplace

     In the past year we have begun to shift our business focus from producing
hardware to designing and implementing full computing solutions. These computing
solutions are intended for use in service bay, test and measurement, and
logistics management applications in the trucking, public services, heavy
equipment and government/military industries worldwide. To produce these
solutions, we combine appropriate hardware, software and peripherals and also
provide service and support. To succeed with this new approach, we will need to
design, develop, conceptualize and support computing solutions that address the
needs of these vertical markets. We cannot guarantee that we will be able to do
this in a timely, cost-effective manner or that our target markets will accept
the solutions that we do introduce.

We have only limited experience with our solutions-based business model

     We began to shift our business focus in early 1999. For us, this means that
we have only limited experience in operating a solutions-based business from
which to evaluate our business prospects and analyze the risks and uncertainties
that we face. For you, this means that you have limited historical information
from which to evaluate our prospects.

We depend on third-party manufacturers to produce our products

     We depend on third-party manufacturers to manufacture and assemble our
products. This results in dependence on the timely delivery of high quality
products from these manufacturers and may leave us with less flexibility and
control over the manufacturing process than if we conducted these operations
internally. These manufacturers (including the manufacturers of subassemblies
included in our final products) may not timely deliver

                                       8
<PAGE>

the items they are expected to produce. Any occurrence of this sort could
compromise our ability to deliver our products and solutions in a timely
fashion. It could also require us to make alternative arrangements, which might
not be available on acceptable terms or on a timely basis. If we were unable to
make alternative arrangements, our business and financial condition could
suffer.

     We have only recently changed from internally manufacturing our final
products to employing third parties to do so. Therefore we do not have long-
standing relationships or experience with our third-party manufacturers.

Our business may suffer if we do not design and implement appropriate new sales
and marketing strategies in a timely manner

     As we shift our business focus from producing hardware to designing and
implementing full computing solutions, we are also working to build our internal
sales organization, retrain our sales personnel and refine our sales and
marketing strategies. Our business may suffer if we do not design and implement
appropriate strategies in a timely manner. Our business may also suffer if, as a
result of the change in our business focus, we are required to replace
significant numbers of our current sales personnel.

Our failure to anticipate or rapidly respond to changing customer demands could
adversely affect our market position

     Both the computer industry and the diagnostic and data collection
instrument industry are characterized by rapid technological change, including
changes in customer requirements, frequent new product introductions and
enhancements, and evolving industry standards. Our success will depend in part
on our ability to keep pace with technological developments and emerging
industry standards and to respond to customer requirements by enhancing our
current products and developing and introducing new solutions and products. Our
market position will be adversely affected if we do not adequately anticipate or
rapidly respond to changes of this type. Technological advances may also
increase the level of competition in our market niche.

Intense competition could reduce our market share and harm our financial
performance

     We occupy a niche in the portable computer market. In this niche, we
currently face direct competition from companies that produce portable computers
intended for field use such as Dolch Computer Systems; Getac Corp.; Itronix
Corp.; Kontron Elektronik Corp., Paravant Computer Systems, Inc.; Motorola,
Inc.; Melard Technologies, Inc.; WPI Husky Computers Inc.; Intermec Technologies
Corp. and Panasonic Personal Computer Company. Our computing platforms also face
indirect competition from a variety of different companies and products,
including consumer portable personal computers, customized portable personal
computers and single-purpose diagnostic and data collection instruments.

     Both the computer industry and the diagnostic and data collection
instrument industry are intensely competitive. To the extent that we and our
current direct competitors expand and develop the market niche that we currently
service, other manufacturers may turn their attention to it and begin to produce
products directly competitive with those we offer. Many of the companies that
produce or may produce devices that compete or may compete, directly or
indirectly, with ours have greater name recognition, larger client bases and
substantially more financial, technological and marketing resources than we do.
These factors may provide them with significant advantages over us. Among other
things, these factors may allow them to adapt more rapidly and effectively to
changes in technology or in the market or to develop or market products that
will be more widely accepted. Competitive pressures could result in reduced
market share, price reductions, reduced margins and increased spending on
marketing and product development, any of which could adversely affect our
business.

If we do not adequately manage our inventory we may be required to make write-
offs in the future

     In the past, we have written off portions of our parts inventory that have
become obsolete. If our current policies aimed at preventing a recurrence prove
ineffective, we may be required to do so again. Any significant future write-
offs could have an adverse effect on our financial condition. Our current effort
to outsource all of our

                                       9
<PAGE>

assembly operations may increase the risk of an additional build-up of excess or
obsolete inventory that leads to a write-off.

Our business may suffer if we fail to manage growth effectively

     To grow successfully we must increase our professional services and
solutions offerings and also improve the efficiency of our operations. If we
succeed in this, it will place significant strain on our managerial, operational
and financial systems and resources. We may not be able to successfully plan for
or manage increased production and marketing of our products and services. If we
grow, we may encounter difficulties, including:

     .    problems with our manufacturing partners;

     .    disrupted quality control and assurance;

     .    decreased product reliability;

     .    increased costs;

     .    difficulties maintaining internal accounting controls;

     .    malfunctioning of existing and new equipment;

     .    insufficient or untimely component supplies; and

     .    personnel shortages.

If we are unable to manage growth effectively, our business could suffer.

We may not succeed in attracting and retaining the personnel we need for our
business

     Our future success depends substantially on our ability to attract and
retain the personnel we need for our business. Our personnel needs include
highly trained personnel for management, sales and engineering. Qualified
individuals in these areas are in high demand and are often subject to competing
employment opportunities. In recent years there has been great demand for
qualified employees in the Minneapolis area, where our headquarters are located.
We may not succeed in attracting and retaining the personnel we need for our
business.

     We have experienced a high turnover rate in some of our significant
management positions over the past three years. In that period we have had four
Chief Executive Officers, three Vice Presidents of Sales and Marketing and two
Vice Presidents of Engineering/Operations. Continued high turnover in these or
similar positions could have an adverse effect on our operations and business.

Adverse events with respect to our international sales could have an adverse
effect on our business and financial condition

     In the year ended January 2, 2000, international sales represented
approximately 14% of our net sales. International sales are subject to inherent
risks, including:

     .    longer payment cycles;

     .    greater difficulty or delay in accounts receivable collection;

     .    U.S. and foreign import and export restrictions and tariffs;

     .    the burdens of complying with a variety of foreign laws;

                                       10
<PAGE>

     .    potentially adverse tax consequences;

     .    potentially inadequate protection of intellectual property rights;

     .    restrictions on repatriation of earnings; and

     .    exposure to increased political and economic instability.

     All of our export sales are currently denominated in United States dollars.
An increase in the value of the United States dollar relative to foreign
currencies could make our products more expensive and, therefore, potentially
less competitive in foreign markets. In the future, if we were to denominate our
export sales in foreign currencies, our financial condition and results of
operations would become subject to foreign currency translations and the
possibility of currency exchange or price controls or other restrictions on
foreign currencies. If any of these events occurred, or if we lost a key foreign
distributor or were unable to maintain our foreign distribution network, it
could have an adverse effect on our business and financial condition.

We depend on resellers for our product distribution

     We distribute a substantial portion of our products through independent
sales representatives and distributors. We also sell our products to value-
added-resellers (known as VARs), distributors and systems integrators. Our
success depends in large part upon the performance of these resellers and on our
ability to attract new resellers. Many of our resellers also carry - and may
have incentives to encourage purchase of - competitive products. Most of our
resellers may terminate their written agreements with us with or without cause
by giving us 30 days' written notice. The loss of any of our major resellers or
a failure to make acceptable arrangements with resellers in new markets could
have a material adverse effect on us.

We obtain a number of our components from single sources

     Our rugged computing platforms employ a number of components not generally
used in off-the-shelf personal computers, such as special hard disk drives, CD-
ROM drives, floppy disk drives, displays and power supplies. We currently obtain
a number of these components from single sources. It could create uncertainty
and be costly and time-consuming if we had to change suppliers. If we could not
obtain adequate or timely quantities of necessary components from our current
suppliers, we might not be able to identify or access alternative sources within
a reasonable period of time, on acceptable terms, or at all. Some of our current
vendors use tools that have been designed for us and are our property. If we
were required to change suppliers for these components, we would need either to
move the necessary tools or to obtain new tools, either of which could entail
significant cost and delay. Moreover, our buying power may be limited by our
small volume and we may receive less favorable allocations and other terms such
as price, timing or other factors than larger companies buying from the same
suppliers. Any of these factors or a significant increase in the price of
components could have a material adverse effect on our ability to manufacture
and market our products.

Potential fluctuations in our quarterly financial results make financial
forecasting difficult

     Our quarterly operating results may fluctuate significantly in the future
as a result of a variety of factors, many of which are outside our control.
These factors include:

     .    long customer sales cycles (especially for customers that are
          government agencies or large corporations);

     .    changes in customer buying patterns;

     .    orders from significant customers in one quarter that are
          disproportionate in size or value compared to our other orders;

     .    the timing and nature of customer returns;

                                       11
<PAGE>

     .    the timing of the introduction of new products by us or our
          competitors;

     .    our competitors' tactics;

     .    technological developments; and

     .    the overall strength of the economy.

     All of these factors, along with the uncertainties associated with the
introduction of any new product or product enhancement, in gauging ultimate
customer demand, and in predicting general trends in the market for our
products, solutions and services, may limit our ability to plan for production
and to forecast quarterly results of operations accurately. We believe that
quarter-to-quarter comparisons of our operating results may not be a good
indication of our future performance. Investors should not rely on our operating
results for any particular quarter as an indication of our future operating
results.

                    Risks Related to Intellectual Property

Failure to protect our intellectual property rights could harm our brand and our
ability to compete effectively

     We rely on a combination of unpatented trade secrets and know-how and on
the expertise of our employees. We do not rely on patented processes or
technologies. The protective steps we have taken may be inadequate to deter
misappropriation of our proprietary information. We may be unable to detect the
unauthorized use of, or take appropriate steps to enforce, our intellectual
property rights. Effective trade secret protection may not be available in every
country in which we offer or intend to offer our products and services.
Likewise, others may independently develop or otherwise acquire unpatented
and/or patented technologies or products similar or superior to ours. We have
four registered trademarks in the United States. We also claim trademark rights
in an additional mark that we use in connection with our products in the United
States. We are aware that there are third parties that have claimed or may claim
superior rights, in some U.S. territories, to use marks in which we also claim
rights. One or more of these third parties may contest our right to use or
register our trademarks or contest the registration of any or all of our
registered trademarks. We do not know whether any of the trademarks we may
attempt to register will be found registrable, that registrations will issue, or
that we can support the cost of defense of our trademarks. Failure to protect
our intellectual property adequately could harm our brand and affect our ability
to compete effectively. Defending our intellectual property rights could also
result in the expenditure of significant financial and managerial resources,
which could materially adversely affect our business.

Loss of software licenses could have an adverse effect on us

     We license some of the software that we include in our products from third
parties. If any licensor terminated any of these licenses, we might not be able
to license similar software from another party in a timely fashion, on
acceptable terms, or at all.

We may have to defend against intellectual property infringement claims, which
could have an adverse effect on us whether or not we prevailed

     Disputes over intellectual property are frequent in the high technology
area. Although we believe that our business activities do not infringe the
intellectual property rights of others, other parties may assert infringement
claims against us or claim that we have violated a patent or other proprietary
right belonging to them. Likewise, disputes may arise in the future with respect
to ownership of technology developed by employees who were previously employed
by other companies. Infringement claims, even if not meritorious, could result
in the expenditure of significant financial and managerial resources. An adverse
determination could subject us to significant liabilities, require us to seek
licenses from or pay royalties to third parties or require us to develop
appropriate alternative technology. We might not be able to do any of these
things on acceptable terms, at an acceptable price, or at all. Any of these
results could materially adversely affect our business.

                   Risks Related to Our Financial Condition

When our line of credit expires in November 2000 we may be unable to renew or
replace it with alternative financing

     Since 1998 we have depended on our line of credit for many of our operating
capital needs. This line of credit expires in November 2000. We may be unable to
renew or replace it on acceptable terms. If this happened, we would have to
repay all amount outstanding at the time (as of March 30, 2000 we had $550,000
outstanding). We might not be able to do so. If we were able to repay all
outstanding amounts, those amounts, coupled with the loss of access to our
credit facility, could adversely affect our financial condition. If we were not
able to repay all outstanding amounts, the lender could take various legal steps
against us, including taking action with respect to items subject to a security
interest we have granted the lender. Items we have pledged include our
equipment, inventory, receivables, investment properties, deposit accounts and
general intangibles.

We have outstanding $3,000,000 of subordinated notes that mature in September
2001

     We have $3,000,000 of subordinated notes outstanding. These notes mature in
September 2001. We may not be able to refinance these notes when they mature,
thus requiring us to repay them in full. If we are able to do so, the need to
use cash in that manner could adversely affect our financial condition.

Failure to satisfy the covenants under our line of credit would give the lender
the right to require immediate repayment

     Our line of credit facility requires us to satisfy a number of covenants
during fiscal year 2000, including the requirement that at the end of each
quarter we have achieved a cumulative net profit before income tax on a year-to-
date basis. If we do not satisfy these covenants, the lender may request
immediate payment of all amounts outstanding ($550,000 as of March 30, 2000). If
the lender were to do so, we might not be able to repay the amounts and the
lender could take various legal steps against us, including taking action with
respect to items subject to a security interest we have granted the lender.
Items we have pledged include our equipment, inventory, receivables, investment
properties, deposit accounts and general intangibles. Even if we were able to do
so, the need to use cash in that manner, coupled with the loss of access to our
credit facility, could adversely affect our financial condition.

The Nasdaq National Market has initiated delisting proceedings against us

     By means of a letter dated November 24, 1999, the Nasdaq National Market
notified us that we did not meet the continued listing requirement with respect
to net tangible assets. On February 24, 2000, we attended an oral hearing before
a panel authorized by the Nasdaq Stock Market's board of directors at which we
stated our belief that, based on our recent capital raising efforts, we should
satisfy the Nasdaq National Market's continued listing requirements. Nasdaq has
not yet informed us of its final decision on this matter. If Nasdaq delists our
common stock from the National Market, it may be more difficult for shareholders
to trade our common stock. It may also make future capital-raising efforts on
our part more expensive and time-consuming. Finally, if Nasdaq delists our
common stock from the National Market or gives us notice of a decision to do so,
then Industrial-Works Holding Co., LLC's minimum purchase commitment in this
offering expires.

We may need to raise additional cash in the future but may not be able to do so

     If we sell all of the shares offered, we believe that the proceeds of this
offering will be sufficient to fund our operations and to maintain our net
tangible assets for continued listing on the Nasdaq National Market through the
end of 2000. However, our actual cash needs may vary significantly from our
projections -- for example, if we do not achieve the revenues we currently
project or if we are unable to replace our line of credit when it expires. We
cannot assure you that our estimates regarding our cash needs will prove
accurate. If our estimates as to future cash needs are wrong or if we do not
sell a significant portion of the shares offered, we may soon need additional
capital. We may not, however, be able to access sufficient capital when required
on favorable terms, if at all. If we raise additional funds by issuing equity
securities, existing shareholders may experience dilution in their ownership

                                       13
<PAGE>

interest. If we raise additional funds by issuing debt securities, we may incur
significant interest expense and become subject to covenants that could limit
our ability to operate and fund our business. If we cannot obtain additional
funds when required, we may be unable to realize our current plans and may even
be forced to cease operations.

     Our subordinated notes, our line of credit, our agreements with Industrial-
Works Holding Co., LLC (the holder of our series B and series C preferred stock)
and the terms of our series B and series C preferred stock all contain covenants
that limit our ability to incur indebtedness. These covenants may restrict our
options for future financing.

                   Risks Related to Our Corporate Structure

One of our shareholders owns a significant percentage of our outstanding stock
and by virtue of that ownership and various charter and contractual rights has
significant influence over our operations and strategic direction

     As of April 2, 2000, one of our shareholders, Industrial-Works Holding Co.,
LLC (which is wholly-owned by Glenmount International, L.P.), owned or had the
right to acquire up to approximately 29% of our outstanding common stock on a
fully diluted basis (assuming exercise of warrants that Industrial-Works owns
and the conversion of all its outstanding shares of preferred stock). If we have
not sold at least $5,000,000 of our common stock in this rights offering on or
before June 30, 2000, the conversion price of our series C preferred stock (all
of which Industrial-Works owns) will adjust from $2.00 to $1.00. If this occurs,
or if Industrial-Works acquires a disproportionate number of the shares of
common stock subject to the rights offering (which is likely), Industrial-Works'
fully-diluted ownership would increase even further.

     The terms of our series B preferred stock, all of which Industrial-Works
owns, and the terms of the agreement under which Industrial-Works purchased
those shares provide that for so long as any shares of series B stock or the
warrant that we issued to Industrial-Works remain outstanding, the holders of
the series B preferred stock (currently Industrial-Works) shall have the right
to elect three of the seven current members of our board of directors. Three
directors currently serving on our board of directors were elected by
Industrial-Works pursuant to these provisions. In addition, since we have failed
to meet financial goals specified in the terms of our series B preferred stock
and the series B preferred stock purchase agreement, the holder of a majority of
the series B preferred stock (currently Industrial-Works) may increase the
number of members of our board of directors by two (to nine) and elect the two
additional members (which would give Industrial-Works the right to elect a
majority of our directors). Finally, Industrial-Works and shareholders holding
approximately 21% of our outstanding common stock have entered into a voting
agreement pursuant to which those shareholders have agreed, until February 2003,
to vote all of their shares in favor of the election of the nominees designated
by Industrial-Works.

     The terms of both our series B and our series C preferred stock (all of
which Industrial-Works owns) and the terms of the agreements under which
Industrial-Works purchased these shares of stock contain significant
restrictions on our ability to enter into a wide variety of transactions without
the prior approval of two-thirds of the holders of each series.

     All of these circumstances give Industrial-Works significant influence on
our operations and strategic direction. Industrial-Works' ownership may also
have the effect of delaying, deterring or preventing a change in control or a
change in the composition of our board of directors.

Our series B and series C preferred stock, our charter documents and Minnesota
law may discourage a takeover of our company

     The terms of our series B and series C preferred stock and provisions of
our articles of incorporation, bylaws and Minnesota law could make it more
difficult for a third party to acquire us, even if doing so would be beneficial
to our shareholders.

                                       14
<PAGE>

Some of our existing agreements prevent us from paying dividends, which we have
no current intention of doing, anyway

     Our subordinated notes and our line of credit contain a covenant that
prohibits us from declaring or paying any dividend (other than a dividend
payable in capital stock). In addition, we currently intend to retain any
earnings for use in the operation and expansion of our business and therefore do
not anticipate paying any cash dividends in the foreseeable future.

                         Risks Related to The Offering

We may close on the sale of significantly fewer shares than we are offering

     We have not set any minimum number of shares of common stock that we will
issue on exercise of the rights, although Industrial-Works Holding Co., LLC, the
sole holder of our series B and series C preferred stock, has agreed to purchase
a minimum of 1,000,000 shares in this rights offering if other shareholders
purchase at least 1,500,000 shares. However, this commitment will expire if this
rights offering is not completed by June 30, 2000 or if, prior to the completion
of this rights offering, our common stock ceases to be admitted to trading on
the Nasdaq National Market or we are given notice of a decision to cause a
delisting. Accordingly, we may close on the sale of significantly fewer shares
than we are offering. If this occurred, it could adversely affect our financial
condition and our likelihood of continued Nasdaq National Market listing. Under
the terms of our series C preferred stock, if we have not sold at least
$5,000,000 of our common stock in this rights offering on or before June 30,
2000, the conversion price for the series C shares, which is currently $2.00 per
share, will be reduced to $1.00 per share.

You may not revoke your exercise of rights; we may cancel the rights offering

     Once you have exercised your rights, you may not revoke your exercise. We
may cancel this rights offering in our discretion. In that case, neither we nor
the subscription agent will have any obligation to you with respect to the
rights except to return any payment of the subscription price received by the
subscription agent, without interest or penalty.

If you do not exercise all of your rights, your ownership interest in FieldWorks
will be diluted

     If we issue all of the shares of common stock offered by this prospectus,
we will issue an additional _______ shares of common stock, which represents
approximately ___% of the shares of common stock we had outstanding (on an
as-if-converted basis) on April 2, 2000. Holders of our stock that elect not to
exercise their rights will accordingly experience dilution in their level of
ownership in FieldWorks.

We set the exercise price for the subscription rights without regard to net
worth, earnings or any other similar value, and you should not consider this
price to be an indication of the actual value of our common stock

     We have set the $2.00 subscription price on the shares of common stock
subject to the rights at a price less than the market price on the date on which
we determined to proceed with this offering. We selected this price based on a
number of factors, including the desire to encourage shareholder participation
in this offering. However, you should not consider this price to be an
indication of the actual value of our common stock and was not based on our net
worth, earnings or any other established criteria of value. This price may not
be indicative of the price that

                                       15
<PAGE>

will prevail in the public market after the offering. In particular, the market
price of our common stock may decline below $2.00.

Management could spend or invest the proceeds of this offering in ways with
which you may not agree

     Our management will have significant discretion in applying the net
proceeds of this offering, and may spend or invest the proceeds from this
offering ineffectively or in ways with which you may not agree.

You will incur immediate and substantial dilution

     If you exercise your rights to purchase shares of our common stock, you
will incur immediate and substantial dilution in net tangible book value per
share.

                   WARNING ABOUT FORWARD-LOOKING STATEMENTS

     This prospectus and the documents incorporated by reference in it include
forward-looking statements. We have based these statements on our current
expectations and projections about future events. These forward-looking
statements include statements about:

     .    our strategies;

     .    the future growth of our market and business;

     .    trends based on our perceptions of past activity; and

     .    other statements that are not historical facts.

     When used in this prospectus, the words "anticipate," "believe," "expect,"
"estimate" and similar expressions are generally intended to identify forward-
looking statements. Our actual results may vary materially from those

                                USE OF PROCEEDS

     We estimate our net proceeds from the sale of the      shares of our common
stock offered to be approximately $ million, after deducting our estimated
offering expenses.

     We intend to use the net proceeds from this offering for general corporate
purposes including future development of computing solutions and market
expansion. We expect that the proceeds from this offering (assuming that we sell
all of the shares of common stock that are subject to the rights offering) will
be sufficient to meet our needs at least through the end of 2000.

     In addition, we may acquire businesses, products and technologies that are
complementary to ours, and a portion of the net proceeds may be used for these
acquisitions. We have no agreements with respect to any material acquisitions as
of the date of this prospectus.

     Pending these uses, we intend to invest the net proceeds from this offering
in short-term, investment-grade, interest-bearing securities.

      On March 31, 2000, the closing bid price of our common stock as reported

                                DIVIDEND POLICY

     Our subordinated notes and our line of credit contain a covenant that
prohibits us from declaring or paying any dividend (other than a dividend
payable in capital stock). In addition, we currently intend to retain any
earnings for use in the operation and expansion of our business and therefore do
not anticipate paying any cash dividends in the foreseeable future.

<PAGE>

                      DETERMINATION OF SUBSCRIPTION PRICE

     We determined the $2.00 subscription price following discussions with
Industrial-Works Holding Co., LLC our largest shareholder and the sole holder of
our two outstanding series of preferred stock. We based this price on a number
of factors, including the desire to encourage shareholder participation in this
offering. We did not base it on our net worth, earnings or any other established
criteria of value and we did not discuss this price with any independent third
party. As a result, you should not consider this price to be an indication of
the actual value of our common stock. This price may not be indicative of the
price that will prevail in the public market after the offering. In particular,
the market price of our common stock may decline below $2.00.

                                   DILUTION

     If you exercise your subscription rights, your interest with respect to
those shares of common stock will be diluted to the extent of the difference
between the subscription price per share of and the pro forma net tangible book
value per share of our common stock after this offering. Pro forma net tangible
book value per share is equal to our total tangible assets less total
liabilities, divided by the number of outstanding shares of common stock after
giving pro forma effect to the conversion of our outstanding preferred stock,
which does not convert in connection with this offering, at currently effective
conversion rates. The dilution in pro forma net tangible book value per share
represents the difference between the amount per share paid by those who
exercise their subscription rights in this offering and the pro forma net
tangible book value per share of common stock immediately after completion of
this offering.

     Our pro forma net tangible book value as of January 2, 2000 was $6,653,381,
or $0.49 per share of our common stock and preferred stock on an as-if-converted
basis. After giving effect to the sale of all of the estimated 4,548,142 shares
of our common stock subject to the rights offering and after deducting our
estimated offering expenses, our pro forma net tangible book value as of January
2, 2000 would have been approximately $15,449,665, or $0.85 per share. This
represents an immediate dilution of $1.15 per share to those shareholders who
exercise their subscription rights with respect to the shares so purchased. The
following table illustrates this per share dilution:

</TABLE>

     The above discussion and table both:

     .    Assume that we sell all of the shares of our common stock that are
          subject to the rights offering. However, we have not set any minimum
          number of shares of common stock that we will issue on exercise of the
          rights and we may close on the sale of significantly fewer shares than
          we are offering. Under the terms of our series C preferred stock, if
          we have not sold at least $5,000,000 of our common stock in this
          rights offering on or before June 30, 2000, the conversion price for
          the series C shares, which is currently $2.00 per share, will be
          reduced to $1.00 per share. This would result in further dilution to
          those shareholders who exercise their subscription rights.

     .    Exclude all of our options and warrants. At April 3, 2000, we had
          reserved 1,786,200 shares of common stock for issuance on exercise of
          outstanding options with a weighted average exercise price of $2.36
          per share, and 2,788,654 shares of common stock issuable upon exercise
          of outstanding warrants with a weighted average exercise price of
          $2.02 per share.

                                CAPITALIZATION

     The following table sets forth our capitalization as of January 2, 2000 as
follows:

     1)   on an actual basis;

     2)   on a pro forma basis to reflect:

          .    the issuance of 4,250,000 shares of series B preferred stock at
               $1.00 per share and the issuance of 500,000 shares of series C
               preferred stock at $2.00 per share;

          .    a preferred stock dividend of approximately $250,000 representing
               the fair value of the beneficial conversion feature on the
               issuance of the series C preferred stock in March 2000 (the
               beneficial conversion feature was calculated at the issuance date
               of the series C preferred stock based upon the difference between
               the conversion price of $2.00 per share and the estimated fair
               value of the common stock at that date); and

     3)   on a pro forma as adjusted basis to reflect the sale of the estimated
          4,548,142 shares of common stock at $2.00 per share in this offering,
          after deducting estimated offering expenses of $300,000.

                              THE RIGHTS OFFERING

General

         We are distributing to the holders of our common stock and our
preferred stock, at no cost to the holders, non-transferable rights to purchase
shares of our common stock. We will give each shareholder who owned shares at
the end of the day on April 14, 2000, the record date, one subscription right
for each three shares of common stock or three shares of common stock issuable
upon conversion of preferred stock owned. We will not issue fractional rights;
the number of rights we offer to each shareholder will be rounded up or down to
the nearest whole number.

         Each right includes a basic subscription privilege and an
oversubscription privilege.

         We are offering the shares of common stock to be issued on exercise of
the subscription rights directly to our shareholders as of the record date. We
estimate that our expenses in connection with this offering will be $300,000.

         There will be no public market for the rights.

         You may not sell, assign or otherwise transfer your rights, except by
operation of law in the event of your death or dissolution.

Basic Subscription Privilege

         Each right will entitle you, upon payment of $2.00 to us, to receive
one share of our common stock. We will send you certificates representing shares
you purchase as soon as practicable after, 2000, whether you exercise your
rights immediately before that date or earlier. If you hold your common stock
through The Depository Trust Company ("DTC"), or arrange for delivery and
payment through DTC, DTC will credit the appropriate account for the shares you
purchase.

Oversubscription Privilege

         Each right also gives you an "oversubscription privilege" to purchase
additional shares of our common stock that other shareholders do not purchase.
You may exercise your oversubscription privilege only if you exercise your basic
subscription privilege in full. The subscription price for any oversubscription
shares you purchase will be $2.00.

         If you want to exercise your oversubscription privilege, you should
indicate the number of additional shares that you would like to purchase in the
space provided on your subscription certificate. In this case, when you send in
your subscription certificate you must send the full purchase price for the
number of oversubscription shares that you have requested in addition to full
payment for shares you are purchasing pursuant to your basic subscription
privilege.

         If the number of shares remaining after the exercise of all basic
subscription privileges is not sufficient to satisfy all oversubscription
privileges, you will be allocated shares pro rata (subject to rounding to
eliminate fractional shares) in proportion to the number of shares that you
purchased by exercising your basic subscription privilege.

         As soon as practicable after ______, 2000, the Subscription Agent will
determine the number of shares of our common stock that you may purchase
pursuant to the oversubscription privilege. We will send you certificates
representing these shares as soon as practicable after, 2000. If you request
and pay for more oversubscription shares than are allocated to you, we will
refund the amount of the overpayment, without interest.

         Banks, brokers and other nominee holders who act on behalf of
beneficial owners will have to certify to us and to the Subscription Agent as to
the aggregate number of rights that they are exercising and the number of shares

                                       20
<PAGE>

of our common stock that they are requesting pursuant to the oversubscription
privilege on behalf of each beneficial owner.

Expiration Time

         The rights will expire at 5:00 p.m. Central Daylight Savings time on
______, 2000, unless we, in our discretion, extend the expiration date for up to
ten days (but no later than 5:00 p.m. Central Daylight Savings time on _____,
2000). If you do not exercise your basic subscription privilege and your
oversubscription privilege (if you so desire) prior to that time, your
subscription rights will cease and be null and void. We will not be required to
issue shares of our common stock to you if the Subscription Agent receives your
subscription certificate or your payment after that time, regardless of whether
you sent the subscription certificate and payment, unless you sent them in
compliance with the guaranteed delivery procedures described below.

Industrial-Works Holding Co., LLC Minimum Purchase Commitment

         By means of a letter dated March 31, 2000, Industrial-Works Holding
Co., LLC, the sole holder of our series B and series C preferred stock, agreed
to purchase a minimum of 1,000,000 of the shares of our common stock subject to
this rights offering. This commitment is subject to the requirements that:

         .     other shareholders purchase at least 1,500,000 shares; and

         .     the subscription price be $2.00 per share.

If we change the price with Industrial-Works' consent, Industrial-Works has
agreed to purchase $2,000,000 in value provided that other shareholders purchase
at least $3,000,000 in value.

         Industrial-Works' commitment will expire if:

         .     this rights offering is not completed by June 30, 2000; or

         .     prior to the completion of this rights offering, our common stock
               ceases to be admitted to trading on the Nasdaq National Market or
               if we are given notice of a decision to cause a delisting.

         Industrial-Works has reserved the right to purchase its full allocation
in the rights offering and to exercise its oversubscription privilege.

         As the result of one of our agreements with Glenmount, LLC (an
affiliate of Industrial-Works), if Industrial-Works purchases its full
commitment in this rights offering, we will be required to pay Glenmount, LLC
$80,000 (four percent of the $2,000,000 commitment). If Industrial-Works
exercises its oversubscription privilege and we issue oversubscription shares to
it, this amount - which is set at four percent of the amount of our securities
that Industrial-Works purchases - will be even larger.

No Board Recommendation

         You must make your decision whether to exercise your subscription
rights based on your own evaluation of your situation and our offer. Our board
of directors does not make any recommendation to any holder of subscription
rights regarding the exercise of those rights.

Exercise of Subscription Rights

         Important

         Please carefully read the instructions accompanying the subscription
certificate and follow those instructions in detail. Do not send subscription
certificates to FieldWorks.

         You are responsible for choosing the payment and delivery method for
your subscription certificate, and you bear the risks associated with your
choices. If you choose to deliver your subscription certificate and payment by
mail, we recommend that you use registered mail, properly insured, with return
receipt requested. We also recommend that you allow a sufficient number of days
to ensure delivery to the subscription agent and clearance of payment prior to
_________, 2000. Because uncertified personal checks may take at least five
business days to clear, we strongly urge you to pay, or arrange for payment, by
means of certified or cashier's check , money order or wire transfer of funds.

         Method of Exercise

         You may exercise your subscription rights by delivering to the
subscription agent, Norwest Bank Minnesota, National Association, on or prior to

         1.    the properly completed and signed subscription certificate
               accompanying this prospectus;

         2.    any required signature guarantees; and

         3.    payment in full of the subscription price for all of the shares
               of common stock you wish to purchase by exercising your basic
               subscription privilege and your oversubscription privilege.

         You should deliver your subscription certificate and payment in the
enclosed envelope to the address set forth below under " - Subscription Agent."

         Method of Payment

         You must pay for the shares of common stock you subscribe for by means
of (1) check or bank draft (cashier's check) drawn on a United States bank or a
postal, telegraphic or express money order payable to "Norwest Bank Minnesota,
National Association," as subscription agent or (2) wire transfer of funds to an
account maintained by the subscription agent for the purpose of accepting
subscriptions at NORWEST SHAREOWNER SERVICES, WIRE CLEARING ACCOUNT,
ABA#091000019, Account #: 1067899, Attn: Juli Harless (FieldWorks,
Incorporated). You will have paid the subscription price only:

         .     in the case of an uncertified check, when it has cleared;

         .     in the case of an certified check or bank draft on a United
               States bank or a postal, telegraphic or express money order, when
               the subscription agent has received it; or

         .     in the case of a wire transfer, when the subscription agent's
               account designated above has received the funds.

         An uncertified personal check may take at least five business days to
clear. Accordingly, if you intend to pay using an uncertified personal check, we
urge you to make payment sufficiently in advance of ________, 2000 to ensure
that the payment can clear before that date. We also urge you to consider paying
with a certified or cashier's check or money order.

subscription certificate to reach the subscription agent on or prior to 5:00

         Signature Guarantee

         Signatures on the subscription certificate must be guaranteed by an

Securities Exchange Act of 1934, subject to the standards and procedures adopted
by the subscription agent. Eligible Guarantor Institutions include banks,
brokers, dealers, credit unions, national securities exchanges and savings
associations.

         Signatures on the subscription certificate do not need to be guaranteed
if the subscription certificate :

         .     provides that the shares of common stock you are purchasing are
               to be delivered directly to the record owner of the subscription
               rights; or

         .     is submitted for the account of a member firm of a registered

               Association of Securities Dealers, Inc., or a commercial bank or
               trust company having an office or correspondent in the United
               States.

         Shares Held for Others

         If you hold shares of common stock for the account of others, such as a
broker, a trustee or a depository for securities, you should notify the
respective beneficial owners of the shares as soon as possible to obtain
instructions with respect to the subscription rights they beneficially own.

         If you are a beneficial owner of common stock held by a holder of
record, such as a broker, trustee or a depository for securities, you should
contact the holder and ask the holder to effect transactions in accordance with
your instructions.

Ambiguities in Exercise of the Subscription Rights

         If you do not specify the number of rights being exercised on your
subscription certificate, or if your payment is not sufficient to pay the total
purchase price for all of the shares that you indicated you wish to purchase,
you will be deemed to have exercised the maximum number of rights that could be
exercised for the amount of the payment that the subscription agent receives
from you.

                                       23
<PAGE>

         If your payment exceeds the total purchase price for the number of
shares of common that you have indicated you wish to exercise on your
subscription certificate, your payment will be applied until depleted as
follows:

         1.    to subscribe for the number of shares of common stock that you
               indicated on the subscription certificate(s) that you wish to
               purchase through your basic subscription privilege;

         2.    to subscribe for additional shares of common stock until your
               basic subscription privilege has been fully exercised; and

         3.    to subscribe for additional shares of common stock pursuant to
               your oversubscription privilege (subject to any applicable
               proration).

         We will return any excess payment remaining after the foregoing
allocation to you as soon as practicable by mail, without interest or
deductions.

Validity of Subscriptions

         FieldWorks will determine all questions concerning the timeliness,
validity, form and eligibility of any exercise of subscription rights. We may,
in our sole discretion:

         .     waive any defect or irregularity;

         .     permit a defect or irregularity to be corrected within any period
               of time that we set; or

         .     reject the purported exercise of any right by reason of any
               defect or irregularity.

Any determination we make with respect to these matters will be final and
binding. Subscriptions will not be deemed to have been received or accepted
until the person submitting the subscription has cured all irregularities or we
have waived them. This must occur within any period of time that we, in our sole
discretion, set. Neither FieldWorks nor the subscription agent will:

         .     be under any duty to notify anyone of any defect or irregularity
               in connection with the submission of any subscription
               certificate; or

         .     incur any liability for any failure to give notice of this sort.

Subscribers' Fees and Expenses

         You are responsible for paying all commissions, fees, taxes and other
expenses that you incur in exercising your subscription rights.

No Revocation

         You may not revoke your subscription after the subscription agent

certificate unless you are certain that you want to purchase shares of our
common stock.

         We reserve the right to amend the terms and conditions of this offering
at any time until it has expired and for any reason.

will have no obligation to you other than to return any rights subscription
payment we have received from you, without interest or penalty.

Rights as a Shareholder

         You will not have any rights as a shareholder with respect to shares of
common stock you subscribe for until we issue the certificates representing
those shares.

         We intend to apply to have the shares of common stock to be issued on
exercise of the subscription rights approved for listing on the Nasdaq National
Market.

         The rights themselves are non-transferable and will not be listed on
any national securities exchange or quotation system.

                          RELATED PARTY TRANSACTIONS

     On November 20, 1999, we entered into a Securities Purchase Agreement with
Industrial-Works Holding Co., LLC, a wholly owned subsidiary of Glenmount
International, L.P. Under this agreement we agreed, among other things:

     .    subject to receipt of shareholder approval and other conditions, to
          issue 4,250,000 shares of series B preferred stock and a warrant to
          purchase 500,000 shares of our common stock to Industrial-Works for
          $4.25 million;

     .    to refrain from various actions with respect to "competing proposals"
          in the period from execution of the agreement to the closing on the
          sale of the series B preferred stock;

     .    so long as the warrant and the shares of series B preferred stock to
          be issued remained outstanding, the holders of the series B preferred
          stock will have the right to designate three directors to a board of
          directors that is set at seven members, except that, following the
          occurrence of any one or more "triggering events" (one of which has
          occurred), the holders of the series B preferred stock have the right
          by majority vote to increase the size of our board of directors to
          nine and nominate the directors to fill the two vacancies created;

     .    the right to nominate the two additional directors shall lapse, and
          the number of directors shall be reduced to seven, if the holders of
          the series B preferred stock have not exercised their conversion
          rights within six months of the date on which they increase the board
          size and elect two additional directors;

     .    we must receive the prior affirmative written consent of the holders
          of the warrant and at least two-thirds of the shares of series B
          preferred stock to take various actions, including creating any series
          of stock that is senior to the series B preferred stock, agreeing to
          various events that would constitute a liquidation or merger in which
          our shareholders control less than a majority of the resulting entity
          and entering into various other transactions outside of the ordinary
          course or above set levels;

     .    to pay Industrial-Works' expenses related to the transaction up to
          $50,000; and

     .    to pay Industrial-Works a termination or break-up fee of $500,000 if
          the agreement was terminated under various specified circumstances.

     On November 20, 1999, we also entered into a management services agreement
with Glenmount, LLC, which is the manager of Glenmount International, L.P. Under
this agreement:

     .    Glenmount, LLC has agreed to provide our management with active and
          continuing support in identifying, developing and executing all major
          strategic, acquisition, operational and financial opportunities;

     .    we agreed to pay Glenmount, LLC $10,000 immediately, $10,000 within 30
          days of the date of the agreement, $10,000 within 60 days of the date
          of the agreement and $200,000 at the closing of the series B preferred
          stock purchase transaction;

     .    we may be obligated to pay Glenmount, LLC additional amounts if we
          request them to perform additional services;

     .    our obligations continue for a period of one year; and

     .    we agreed that the management services agreement would terminate if
          the series B securities purchase agreement terminated, subject to our
          obligation to pay the minimum compensation due to

                                       26
<PAGE>

          Glenmount, LLC ($30,000) and to pay $100,000 if the termination was
          the result of our shareholders not approving the transactions
          contemplated by the series B securities purchase agreement.

     On February 18, 2000, we amended our management services agreement with
Glenmount, LLC to address services that Glenmount, LLC had provided that were
beyond the scope of that agreement. We agreed to:

     .    pay Glenmount, LLC an additional $30,000 as additional compensation
          for the initial three-month period of the management services
          agreement;

     .    extend the $10,000 per month fee to Glenmount, LLC for each month
          during the balance of the term of the management services agreement;
          and

     .    pay to Glenmount, LLC an additional fee equal to four percent of the
          purchase price of any securities we issue to Industrial-Works (other
          than the series B preferred stock and the warrants issued to
          Industrial-Works on November 20, 1999), payable on the date that
          Industrial-Works purchases the securities.

As the result of the last of these agreements, if Industrial-Works purchases its
full commitment in this rights offering, we will be required to pay Glenmount,
LLC $80,000. That fee will be higher if Industrial-Works exercises its
oversubscription privilege and we issue oversubscription shares to it.

     On February 18, 2000 we also issued Industrial-Works a warrant to purchase
an additional 100,000 shares of our common stock at an exercise price of $2.00
per share, subject to adjustment for changes to our capitalization and for later
issuances of common stock at price per share less than $2.00. These warrants are
immediately exercisable and expire on February 19, 2005.

     On February 22, 2000, we closed the series B preferred stock transaction
with Industrial-Works. We discuss the terms of the series B preferred stock more
fully under "Description of Capital Stock." At the time of sale, the shares of
series B stock that we issued represented approximately 32% of our shares of
common stock outstanding on an as-if-converted basis. We also issued Industrial-
Works a warrant to purchase 500,000 shares of our common stock at an exercise
price of $1.00 per share, subject to adjustment for changes to our
capitalization and for later issuances of common stock at price per share less
than $1.00. The warrants become fully exercisable and expire on February 27,
2007, but may become exercisable sooner:

     .    as to 167,000 shares (subject to adjustment as described above) if the
          closing price of our common stock averages $2.50 for five consecutive
          trading days, provided that these shares shall not be exercisable more
          than three years after the accelerated vesting (or after the
          expiration date, if that occurs sooner);

     .    as to 167,000 shares (subject to adjustment as described above) if the
          closing price of our common stock averages $3.75 for five consecutive
          trading days, provided that these shares shall not be exercisable more
          than three years after the accelerated vesting (or after the
          expiration date, if that occurs sooner); and

     .    as to the remaining 166,000 (subject to adjustment as described above)
          shares if the closing price of our common stock averages $5.00 for
          five consecutive trading days, provided that these shares shall not be
          exercisable more than three years after the accelerated vesting (or
          after the expiration date, if that occurs sooner).

As required by our management services agreement with Glenmount, LLC, we also
paid Glenmount, LLC $200,000.

     On March 31, 2000, we entered into a Preferred Stock Purchase Agreement
with Industrial-Works. On the same day we closed on the sale of 500,000 shares
of series C preferred stock to Industrial-Works for $1,000,000 or

                                       27
<PAGE>

$2.00 per share. We discuss the terms of the series C preferred stock more fully
under "Description of Capital Stock." Among other things, the Preferred Stock
Purchase Agreement:

     .    gave the holders of the series C preferred stock the right to name an
          observer to our board of directors unless the holders of the series B
          preferred stock hold at least 50% of the series C preferred stock;
          and

     .    requires the prior affirmative written consent of the holders of at
          least two-thirds of the shares of series C preferred stock to take
          various actions, including creating any series of stock that is senior
          to the series C preferred stock, agreeing to various events that would
          constitute a liquidation or merger in which our shareholders control
          less than a majority of the resulting entity and entering into various
          other transactions outside of the ordinary course or above set levels.

At the time of the sale, these shares of series C preferred stock represented
approximately 5% of our shares of common stock outstanding on an as-if-converted
basis. In connection with this transaction, we paid Glenmount, LLC $40,000 under
our management services agreement as supplemented.

     On March 31, 2000, Industrial-Works also agreed to purchase a minimum of
1,000,000 of the shares of our common stock subject to this rights offering.
This commitment is described in greater detail above under the caption "The
Rights Offering - Industrial-Works Holding Co., LLC Minimum Purchase
Commitment."

     As provided by our agreements with Industrial-Works and the terms of our
series B preferred stock and series C preferred stock, Industrial-Works
nominated three of our directors. All three of these directors are affiliated
with various Glenmount entities as follows:

     .    Richard J. Boyle is a director of Glenmount Investment, LLC (which is
          the general partner of Glenmount International, L.P.);

     .    Robert D.D. Forbes is a director of Glenmount Investment LLC and is a
          Managing Director of Glenmount, LLC; and

     .    Michael E. Johnson is a director of Glenmount Investment, LLC and is
          a Managing Director of Glenmount, LLC.

                         DESCRIPTION OF CAPITAL STOCK

     We are authorized to issue 35 million shares of capital stock, $.001 par
value. Thirty million of these shares are common stock and five million shares
are preferred stock, of which 4,250,000 have been designated Series B
Convertible Participating Preferred Stock, 500,000 have been designated Series C
Convertible Participating Preferred Stock and 250,000 are undesignated as to
rights and preferences. As of April 3, 2000, there were 8,894,426 shares of
common stock outstanding, which were held of record by 156 shareholders,
4,250,000 shares of Series B Convertible Participating Preferred Stock
outstanding, which were held of record by one shareholder, and 500,000 shares of
Series C Convertible Participating Preferred Stock outstanding, which were held
of record by one shareholder.

Common Stock

     The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of shareholders. There is no
cumulative voting for the election of directors, and the holders of more than
50% of the outstanding common stock can elect all directors, subject to the
rights of our outstanding series of preferred stock. Subject to preferences that
may be applicable to any outstanding preferred stock, holders of common stock
are entitled to receive ratably any dividends that our board of directors may
declare out of funds legally available for that purpose and in liquidation
proceedings. Holders of common stock have no preemptive or subscription rights
and there are no redemption rights with respect to shares of common stock. Our
outstanding shares of common stock are, and the shares of common stock we are
offering in this prospectus will be, fully paid and nonassessable.

Preferred Stock

     Series B Convertible Participating Preferred Stock

     Under the terms of our Series B Convertible Participating Preferred Stock:

     .    each share has a liquidation preference of $1.00 plus any accrued and
          unpaid dividends;

     .    each share has the right to participate on an as-if-converted basis
          with our common stock in the distribution of any assets or funds that
          remain to be distributed to shareholders after the liquidation
          preference of all preferred stock (including the series B preferred
          stock) has been paid;

     .    except as otherwise required by law and as otherwise provided, the
          holders vote on an as-if-converted basis as a single class with our
          common stock on all matters submitted to our shareholders;

     .    the holders of the series B preferred stock have the right, voting as
          a class, to elect three directors to a board of directors that is set
          at seven members, except that, following the occurrence of any one or
          more "triggering events" (one of which has occurred), the holders of
          the series B preferred stock have the right by majority vote to
          increase the size of our board of directors to nine and fill the two
          vacancies created;

     .    the right to elect two additional directors shall lapse, and the
          number of directors shall be reduced to seven, if the holders of the
          series B preferred stock have not exercised their conversion rights
          within six months of the date on which they increase the board size
          and elect two additional directors;

     .    we must receive the prior affirmative written consent of the holders
          of at least two-thirds of the shares of series B preferred stock to
          take various actions, including creating any series of stock that is
          senior to the series B preferred stock, agreeing to various events
          that would constitute a liquidation or merger in which our
          shareholders control less than a majority of the resulting entity and
          entering into various other transactions outside of the ordinary
          course or above set levels;

                                       29
<PAGE>

     .    the holder may elect to convert shares of series B preferred stock
          into shares of common stock at a price that is currently equal to
          $1.00 per share, subject to adjustment for changes in our
          capitalization and, with a few exceptions, for issuances of common
          stock or shares convertible into or exercisable for shares of common
          stock at a price less than $1.00 per share; and

     .    if we offer to sell any securities other than debt securities issued
          to financial institutions and options or shares issued to employees,
          directors and consultants, we must first offer the holders of the
          series B preferred stock (or of shares of common stock issued on
          conversion of the series B preferred stock) the right to purchase
          sufficient securities to prevent dilution of the holder's ownership in
          FieldWorks.

     Series C Convertible Participating Preferred Stock

          with our common stock in the distribution of any assets or funds that
          remain to be distributed to shareholders after the liquidation
          preference of all preferred stock (including the series C stock) has
          been paid;

     .    except as otherwise required by law and as otherwise provided, the
          holders vote on an as-if-converted basis as a single class with our
          common stock on all matters submitted to our shareholders;

     .    we must receive the prior affirmative written consent of the holders
          of at least two-thirds of the shares of series C preferred stock to
          take various actions, including creating any series of stock that is
          senior to the series C preferred stock, agreeing to various events
          that would constitute a liquidation or merger in which our
          shareholders control less than a majority of the resulting entity and
          entering into various other transactions outside of the ordinary
          course or above set levels;

     .    the holder may elect to convert shares of series C preferred stock
          into shares of common stock at a price that is currently equal to
          $2.00 per share;

     .    the conversion price for the series C preferred stock is subject to
          adjustment for changes in our capitalization and, with a few
          exceptions, for issuances of common stock or shares convertible into
          or exercisable for shares of common stock at a price less than $1.00
          per share;

     .    the conversion price for the series C preferred stock is subject to
          adjustment from $2.00 to $1.00 if we have not sold at least $5,000,000
          of our common stock in this rights offering on or before June 30,
          2000; and

     .    if we offer to sell any securities other than debt securities issued
          to financial institutions and options or shares issued to employees,
          directors and consultants, we must first offer the holders of the
          series C preferred stock (or of shares of common stock issued on
          conversion of the series C preferred stock) the right to purchase
          sufficient securities to prevent dilution of the holder's ownership in
          FieldWorks.

     Undesignated Preferred Stock

     Our Second Amended and Restated Articles of Incorporation authorize our
board of directors, subject to any restrictions contained within the terms of
any then-outstanding series of preferred stock, without further shareholder
action, to issue preferred stock in one or more series and to fix the voting
rights, liquidation preferences, dividend rights, repurchase rights, conversion
rights, redemption rights, terms, including sinking fund provisions, and certain
other rights and preferences, of any preferred stock so created.

     As of April 3, 2000, we had outstanding warrants to purchase a total of
2,788,654 shares of our common stock at a weighted average exercise price of
$2.02 per share. These warrants are all currently exercisable and expire on

Provisions of Our Articles and Bylaws and Minnesota Law That May Have Anti-
Takeover Effect

     All of the following could have the effect of discouraging certain attempts
to acquire us, which could in turn deprive you of the opportunity to sell your
shares of our common stock at prices higher than prevailing market prices:

     .    the terms of our series B and series C preferred stock, which contain
          limitations on our ability to enter into mergers and other change of
          control transactions;

     .    the existence of authorized but unissued preferred stock;

     .    various provisions of our Second Amended and Restated Articles of
          Incorporation;

     .    various provisions of our Second Amended and Restated Bylaws; and

     .    various provisions of Minnesota law.

     Section 302A.671 of the Minnesota Business Corporation Act applies, with
certain exceptions, to any acquisition of our voting stock (from a person other
than us, and other than in connection with certain mergers and exchanges to
which we are a party) resulting in the beneficial ownership of 20% or more of
our voting stock then outstanding. Section 302A.671 requires approval of any
acquisitions of this type by a majority vote of our shareholders prior to its
consummation. In general, shares acquired in the absence of this approval are
denied voting rights and are redeemable at their then fair market value by us
within 30 days after the acquiring person has failed to give a timely
information statement to us or the date our shareholders voted not to grant
voting rights to the acquiring person's shares.

     Section 302A.673 of the Minnesota Business Corporation Act generally
prohibits any business combination between us, or any of our subsidiaries, and
any shareholder which purchases 10% or more of our voting shares (an "interested
shareholder") within four years following the interested shareholder's share
acquisition date, unless the business combination or the acquisition of shares
is approved by the affirmative vote of a majority of a committee of all of the
disinterested members of our board of directors, before the interested
shareholder's share acquisition date.

Transfer Agent and Registrar

     The Transfer Agent and Registrar with respect to our common stock is
Norwest Bank Minnesota, National Association.

Section 302A.255 (with respect to director conflicts of interest), if
applicable, has been satisfied; (4) in the case of a criminal proceeding, had no
reasonable cause to believe the conduct was unlawful; and (5) in the case of
acts or omissions in such person's official capacity for the corporation,
reasonably believed that the conduct was in the best interests of the
corporation, or in the case of acts or omissions in such person's official
capacity for other affiliated organizations, reasonably believed that the
conduct was not opposed to the best interests of the corporation. Section
302A.521 also requires payment by a corporation, upon written request, of
reasonable expenses in advance of final disposition of the proceeding in certain
instances. A decision as to required indemnification is made by a disinterested
majority of the Board of Directors present at a meeting at which a disinterested
quorum is present, or by a designated committee of the Board, by special legal
counsel, by the shareholders or by a court.

         Provisions regarding indemnification of officers and directors of the
Company to the extent permitted by Section 302A.521 are contained in the
Company's Second Amended and Restated Bylaws (Exhibit 4.2 hereto, which is
incorporated herein by reference).

Item 17. Undertakings.

          (a)  The undersigned registrant hereby undertakes:

                    (1)  To file, during any period in which offers or sales are
          being made, a post-effective amendment to this registration statement:

                           (i)   To include any prospectus required by Section
                    10(a)(3) of the Securities Act of 1933;

                           (ii)  To reflect in the prospectus any facts or
                    events arising after the effective date of the Registration
                    Statement (or the most recent post-effective amendment
                    thereof) which, individually or in the aggregate, represent
                    a fundamental change in the information set forth in the
                    Registration Statement. Notwithstanding the foregoing, any
                    increase or decrease in volume of securities offered (if the
                    total dollar value of securities would not exceed that which
                    was registered) and any deviation from the low or high end
                    of the estimated maximum offering range may be reflected in
                    the form of prospectus filed with the Securities and
                    Exchange Commission pursuant to Rule 424(b) if, in the
                    aggregate, the changes in volume and price represent no more
                    than a 20% change in the maximum aggregate offering price
                    set forth in the "Calculation of Registration Fee" table in
                    the effective Registration Statement; and

                           (iii) To include any material information with
                    respect to the plan of distribution not previously disclosed
                    in the Registration Statement or any material change to such
                    information in the Registration Statement;

          Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above will
          not apply if the Registration Statement is on Form S-3, Form S-8, or
          Form F-3, and the information required to be included in a post-
          effective amendment by those paragraphs is contained in periodic
          reports filed with or furnished by the registrant pursuant to Section
          13 or Section 15(d) of the Securities Exchange Act of 1934 that are
          incorporated by reference in the Registration Statement.

                    (2)  That, for the purpose of determining any liability
          under the Securities Act of 1933, each such post-effective amendment
          shall be deemed to be a new Registration Statement relating to the
          securities offered therein, and the offering of such securities at
          that time shall be deemed to be the initial bona fide offering
          thereof.

                    (3)  To remove from registration by means of a post-
          effective amendment any of the securities being registered which
          remain unsold at the termination of the offering.

          (b)       The undersigned registrant hereby undertakes to supplement
the prospectus, after the expiration of the subscription period, to set forth
the results of the subscription offer and the terms of any subsequent reoffering
thereof.

          (c)       The undersigned registrant hereby undertakes to deliver or
cause to be delivered with the prospectus, to each person to whom the prospectus
is sent or given, the latest annual report, to security holders that is
incorporated by reference in the prospectus and furnished pursuant to and
meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities
Exchange Act of 1934; and, where interim financial information required to be
presented by Article 3 of Regulation S-X is not set forth in the prospectus, to
deliver, or cause to be delivered to each person to whom the prospectus is sent
or given, the latest quarterly report that is specifically incorporated by
reference in the prospectus to provide such interim financial information.

                                      II-5

          (d)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

          (e)  For purposes of determining any liability under the Securities
Act of 1933, the information omitted from the form of prospectus filed as part
of this registration statement in reliance upon Rule 430A and contained in a
form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.

          (f)  For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

Company nor any Person acting on its behalf has taken or will take any other

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.

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

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

   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

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

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

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
of circumstances in connection with which the Company could be subject to any
liability that is reasonably likely to have a Material Adverse Effect. For

incorporated, deemed to be under common control or affiliated with the Company

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.

   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
     such additional services do not arise in connection with any such
     transaction, you shall be entitled to such additional compensation as
     shall be negotiated at the time such services are rendered.

<PAGE>

  5. Investment Banking Services. Further, if you perform additional services
     to initiate a merger, acquisition, disposition, joint venture, financing
     or other similar transaction or expend substantial time on any such
     transaction initiated by others, you shall be entitled to receive
     additional fees of the type customarily received by investment bankers
     on terms satisfactory to the Board of Directors in its reasonable
     discretion.

  6. Term. The term of this Agreement shall be for a period of one year
     commencing on the date hereof. Prior to the expiration of this

     then this Agreement shall immediately terminate. Notwithstanding any
     termination, (x) we will immediately pay you the amounts identified in
     clauses (a), (b) and (c) of paragraph 2 above (to the extent such
     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
     the Securities Purchase Agreement is terminated upon a failure of the
     Company's shareholders to approve the transactions it contemplates,.

  7. Insurance and Indemnity. We agree during the term of this Agreement to
     carry directors' and officers' insurance in an amount not less than $5
     million to include you and your designated persons as additional
     insureds, to the extent our insurance company will permit us to treat
     your assigned persons as consultants. In addition, we hereby agree to

   Please countersign this Agreement in the place indicated below to confirm
your acceptance of an agreement to the terms stated in this letter.

                                          Very truly yours,

                                   ADDENDUM A

   In connection with the engagement described in the foregoing letter
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.

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

                            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:

     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.

and exceptions set forth herein, we are of the opinion that:

         1. The Company is duly incorporated, validly existing and in good

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

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

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

     2. Demand Registrations

          (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.

     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

     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).

          (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
     to be in such denominations and registered in such names as the managing
     underwriter may request at least three business days prior to any sale of
     Registrable Securities to the underwriters;

          (k) use all commercially reasonable efforts to cause the Registrable
     Securities covered by the Registration Statement to be registered with or
     approved by such other governmental agencies or authorities as may be
     necessary to enable the seller or sellers thereof or the underwriters, if
     any, to consummate the disposition of such Registrable Securities;

          (l) if the Registration Statement or the Prospectus contains a
     misstatement, prepare a supplement or post-effective amendment to the
     Registration Statement or the related Prospectus or any document
     incorporated therein by reference or file any other required document so
     that, as thereafter delivered to the purchasers of the Registrable
     Securities, the Prospectus will not contain a misstatement;

          (m) use all commercially reasonable efforts to cause all Registrable
     Securities covered by the Registration Statement to be listed on any
     national securities exchange on which the Company's securities are listed
     or authorized for quotation on Nasdaq, if requested by any Eligible Holder
     or the managing underwriter, if any; provided, however, that the payment of
     any required listing or other fee shall always be deemed to be
     "commercially reasonable" for purposes of this Section 6(m);

          (n) provide a CUSIP number for all Registrable Securities not later
     than the effective date of the Registration Statement;

          (o) enter into such agreements (including an underwriting agreement)

THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, TRANSFERRED OR
OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR
EXEMPTION FROM REGISTRATION UNDER THE FOREGOING LAWS. ACCORDINGLY, THIS WARRANT

                            FIELDWORKS, INCORPORATED

                                     WARRANT
                                   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
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.

          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

          (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
     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 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,

                                       A-7
<PAGE>

     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

               (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
<PAGE>

     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));

          (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
     to be in such denominations and registered in such names

                                       A-9
<PAGE>

     as the managing underwriter may request at least three business days prior
     to any sale of Registrable Securities to the underwriters;

          (k) use all commercially reasonable efforts to cause the Registrable
     Securities covered by the Registration Statement to be registered with or
     approved by such other governmental agencies or authorities as may be
     necessary to enable the seller or sellers thereof or the underwriters, if
     any, to consummate the disposition of such Registrable Securities;

          (l) if the Registration Statement or the Prospectus contains a
     misstatement, prepare a supplement or post-effective amendment to the
     Registration Statement or the related Prospectus or any document
     incorporated therein by reference or file any other required document so
     that, as thereafter delivered to the purchasers of the Registrable
     Securities, the Prospectus will not contain a misstatement;

          (m) use all commercially reasonable efforts to cause all Registrable
     Securities covered by the Registration Statement to be listed on any
     national securities exchange on which the Company's securities are listed
     or authorized for quotation on Nasdaq, if requested by any Eligible Holder
     or the managing underwriter, if any; provided, however, that the payment of
     any required listing or other fee shall always be deemed to be
     "commercially reasonable" for purposes of this Section 6(m);

          (n) provide a CUSIP number for all Registrable Securities not later
     than the effective date of the Registration Statement;

          (o) enter into such agreements (including an underwriting agreement)
     and do anything else reasonably necessary or advisable in order to expedite
     or facilitate the disposition of such Registrable Securities, and in such
     connection, whether or not the registration is an Underwritten
     Registration:

               (1) make such representations and warranties to the Holders of
          such Registrable Securities and the underwriters, if any, in form,
          substance and scope as are customarily made by issuers to holders and
          underwriters, respectively, in similar Underwritten Offerings;

               (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
          Eligible Holder or such underwriters;

                                      A-10
<PAGE>

               (3) obtain "cold comfort" letters and updates thereof from the
          Company's independent certified public accountants addressed to the
          selling Holders of Registrable Securities and the underwriters, if
          any, such letters to be in customary form and covering matters of the
          type customarily covered in "cold comfort" letters to holders and
          underwriters, respectively, in connection with similar Underwritten
          Offerings;

               (4) if an underwriting agreement is entered into, cause the same
          to include customary indemnification and contribution provisions and
          procedures with respect to such underwriters; and

               (5) deliver such documents and certificates as may be reasonably
          requested by any Eligible Holder and the managing underwriter, if any,
          to evidence compliance with clause (1) above and with any customary
          conditions contained in the underwriting agreement or other agreement
          entered into by the Company.

     The above shall be done at each closing under such underwriting or similar
     agreement or as and to the extent otherwise reasonably requested by any
     Eligible Holder;

          (p) make available for inspection by representatives of any Eligible
     Holder, any underwriter participating in any disposition pursuant to such
     Registration Statement, and any attorney or accountant retained by the
     sellers or any such underwriter, all financial and other records and
     pertinent corporate documents and properties of the Company, and cause the

              [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.

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
