  Face it--computers don't just sit on desks any more. Today, many field
professionals take their computers outside the office to service equipment or
implement complex computer systems. Ideally, these professionals would like to
have one tool that addresses all their needs and can withstand outside
environments. Enter FieldWorks platforms--designed to house all tools needed
in ONE rugged package. FieldWorks makes the "toolbox" that accomodates
communications technologies, data acquisition hardware and test
instrumentation for real-time information transfer and efficient problem-
solving. FieldWorks addresses the specialized needs of those professionals who
demand rugged, expandable, upgradeable and customizable computer platforms.

  The following summary should be read in conjunction with, and is qualified in
its entirety by, the more detailed information, including "Risk Factors" and
the Consolidated Financial Statements and Notes thereto, appearing elsewhere in
this Prospectus. Unless otherwise indicated, all information in this
Prospectus, including financial information and share and per share data, (i)
assumes no exercise of the Underwriters' over-allotment option and (ii) gives
effect to the automatic conversion of all outstanding Preferred Stock into
Common Stock upon the consummation of this offering. See "Capitalization,"
"Description of Capital Stock" and "Underwriting."
 
                                  THE COMPANY
 
  FieldWorks, Incorporated ("FieldWorks" or the "Company") designs,
manufactures, markets and supports portable rugged computing platforms and
computer system solutions for use in demanding field environments. In addition
to providing the full range of computer features, performance and functionality
typically found in high-end desktop computers, the Company's portable computing
platforms have been designed to meet rigorous military standards for ruggedness
and to function despite exposure to extreme temperature, mechanical shock,
vibration and moisture. The Company's computing platforms are expandable
through multiple expansion slots to provide a flexible electronic "toolbox"
that can integrate all of a user's application-specific, multi-media and
communications needs into one portable, rugged device. The Company's products
have been designed with a modular system configuration that allows a user to
easily upgrade the central processing unit ("CPU") or any of the other
technological components without purchasing a new computer. Further, the
Company has the ability to customize its computing platforms to meet the unique
needs of its customers.
 
  The worldwide market for portable personal computers is expanding rapidly,
and Frost & Sullivan has predicted that it may reach nearly $80 billion in
annual sales by 2001. Within this market, the market for mobile computing and
field force automation products is predicted to be one of the fastest growing
sectors over the next decade, with annual growth predicted at as much as 35% or
more. According to International Data Corp. ("IDC") estimates, the rugged
portable computer market is currently over $500 million and is expected to grow
by more than 50% over the next three years. Organizations are increasingly
seeking to computerize field personnel, and industries such as
telecommunications, utilities, farming, law enforcement, the military and
transportation have recognized the need for computerization and automation in
the field. However, the effectiveness of these efforts has often been limited
by the nature of the products that have been available. Consumer portable
personal computers frequently become inoperable under field conditions, are
typically available only with a standard set of features that cannot be
expanded or customized to meet the specialized needs of field users, and are
not designed to be upgraded. Similarly, custom-designed portable personal
computers are expensive, generally limited in their applications and often
unable to withstand conditions typically present in the field, while mobile
single-purpose diagnostic and data collection instruments generally have little
independent computing capability.
 
  The Company's products have been designed to accomodate the demands of a wide
variety of users who are looking for mobile computing platforms that are rugged
and expandable, easily upgraded as technology changes and that can be
customized to meet the specialized needs of field force users. The Company
targets those markets that require portable computing platforms that can
perform multiple functions, including diagnostics, data acquisition and
electronic testing and monitoring, and simultaneously provide communications
and computer capability even under adverse conditions in the field. FieldWorks
rugged computing platforms are in use in a variety of market applications,
including: electronic toolboxes for telecommunications test crews to simplify
and expedite installation, repair and troubleshooting tasks; data collection
and transmission for in-flight commercial airplane testing; collection and
analysis of Global Positioning System ("GPS") geographical information and
agricultural data
 
                                       3
<PAGE>
 
to aid in the selection of crops, chemicals and farming methods; diagnostic
system analysis and wireless communication for use with trucking fleets; and
video surveillance and monitoring for law enforcement purposes. The Company
believes that its rugged computing technology has enabled its customers to
create new applications that improve the productivity of their field personnel
and believes further that additional markets and customers will develop as more
businesses recognize the benefits of providing field personnel with effective,
sophisticated computing power.
 
  The Company's objective is to be the leading designer, manufacturer and
marketer of rugged computing platforms and computer system solutions. The
Company's strategy is to: (i) penetrate key vertical markets, (ii) expand
strategic OEM relationships, (iii) establish relationships with large-volume,
repeat customers, (iv) develop new products and enhance existing products and
(v) establish product recognition.
 
  The Company shipped its first commercial product, the 7000 Series Field
WORKSTATION rugged laptop computing platform, which is now offered in a range
of models, in June 1994. In June 1996, the Company commercially introduced its
5000 Series FIELD WORKSTATION rugged notebook computing platform to meet the
needs of customers who require a smaller, more lightweight toolbox but do not
require the full expansion capability of the 7000 Series. The Company is
currently developing additional series of computing platforms designed to
address broader customer preferences for products with varying degrees of
expandability, size and price, all of which provide the ruggedness, processing
power and ease of upgrade that characterize the Company's current products.
 
  The Company assembles its products to its customers' specifications as orders
are received, which enables the Company to provide each customer with a
computing platform that satisfies its specific requirements.
 
  The Company was incorporated under the laws of the State of Minnesota in
October 1992. The Company's executive offices are located at 9961 Valley View
Road, Eden Prairie, Minnesota 55344, and its telephone number is (612) 947-
0856.

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby is speculative
and involves a high degree of risk. In evaluating an investment in the shares
of Common Stock offered by this Prospectus, prospective investors should
carefully consider the following factors, in addition to the other information
in this Prospectus. The discussion in this Prospectus contains certain
forward-looking statements that involve risks and uncertainties. The Company's
actual results could differ materially from those discussed herein. Factors
that could cause or contribute to such differences include, but are not
limited to, those discussed in "Risk Factors," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," and "Business," as
well as those discussed elsewhere in this Prospectus.
 
UNCERTAINTY OF MARKET ACCEPTANCE
 
  The market for rugged computing platforms is a relatively new, limited
sector of the portable computer market. The Company's success will depend upon
increasing the market acceptance of its two current series of products, which
are both heavier and more expensive than most consumer portable personal
computers. There can be no assurance that the Company's products will gain
widespread acceptance or that the Company will generate sufficient sales to
allow the Company to attain profitable operations. In addition, the failure of
the rugged computing platform market to expand would have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Business--Strategy," and "--Markets and Customers."
 
COMPETITION
 
  The Company believes that it currently occupies a niche in the portable
computer market with its rugged computing platforms. The Company currently
faces direct competition in this market niche from companies producing
portable computers intended for field use such as Amrel Technology, Inc.,
Badger Computers (a unit of Group Financial Partners, Inc.), Dolch Computer
Systems, Getac Corporation, Husky Computers Inc., Itronix Corporation, Kontron
Elektronik Corporation (a subsidiary of Kontron Elektronik GmbH) and Panasonic
Personal Computer Company. To the extent FieldWorks and its direct competitors
expand and develop this market niche, other manufacturers may turn their
attention to this niche and begin to produce products directly competitive
with those offered by the Company. The Company's 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 portable computer industry and the diagnostic and data collection
instrument industry are intensely competitive. Many of the companies that
produce or may produce devices that compete, directly or indirectly, with the
Company's products have substantially greater financial, technological and
marketing resources than the Company. There can be no assurance that the
Company will be able to compete effectively against current or future
competitors, or that such competitors will not succeed in adapting more
rapidly and effectively to changes in technology or in the market or in
developing or marketing products that will be more widely accepted. See
"Business--Competition."
 
RISK OF TECHNOLOGICAL OBSOLESCENCE
 
  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. The Company's success will depend in part on
its ability to keep pace with technological developments and emerging industry
standards and to respond to customer requirements by enhancing its current
products and developing and introducing new products. Failure to
 
                                       7
<PAGE>
 
anticipate or respond rapidly to advances in technology and to adapt the
Company's products appropriately could have a material adverse effect on the
success of the Company's products and thus on the Company's business,
financial condition and results of operations. Technological advances may also
increase the level of competition in the rugged computing platform market. See
"Business--Competition."
 
RISKS ASSOCIATED WITH MANAGING GROWTH
 
  If the Company is to grow successfully, it must increase its manufacturing
output and capacity significantly. The anticipated growth of the Company's
operations will place significant strain not only on the manufacturing
resources of the Company, but also on the Company's management, sales and
marketing, operating and financial systems and resources. If such growth
occurs, the Company may encounter difficulties, including problems involving
lower than projected production rates, lower quality control and assurance,
decreased product reliability, increased manufacturing costs, difficulties in
maintaining internal accounting controls, malfunctioning of existing and new
equipment, insufficient or untimely component supplies and shortages of
personnel. There can be no assurance that the Company will be able
successfully to plan for or manage increased production and marketing of its
products. The failure to do so could have a material adverse effect on the
Company's business, financial condition and results of operations. The Company
anticipates that, at projected sales growth levels, it will be required to
move into expanded production and administrative facilities by mid-1997. While
the Company currently anticipates that it will be able to lease appropriate
expansion space for its manufacturing operations as necessary, there can be no
assurance that such facilities will be available when needed on acceptable
terms, if at all, or that such move can be accomplished without impairing the
Company's operations. See "Recent Events," "Business--Manufacturing," "--
Backlog" and "--Facilities."
 
RISKS ASSOCIATED WITH DEVELOPING SALES CHANNELS
 
  The Company is engaged in building its sales organization and refining its
sales strategies. Failure to develop this sales organization sufficiently or
to implement appropriate sales strategies in a timely manner could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
  The Company distributes a substantial portion of its products through
independent sales representatives and distributors. The Company also sells its
products to OEMs, value added resellers ("VARs") and systems integrators. The
success of the Company is dependent in large part upon the performance of
these resellers, many of whom may also carry competitive products, and on its
ability to attract new resellers. The Company operates pursuant to written
agreements, most of which may be terminated by the reseller on 30 days'
written notice with or without cause. The loss of any of the Company's major
resellers or a failure to make acceptable arrangements with resellers in new
markets could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business--Markets and
Customers" and "--Sales and Marketing."
 
DEPENDENCE ON THIRD-PARTY MANUFACTURERS
 
  Although the Company performs some mechanical subassembly and all final
assembly of its products, the Company relies on sub-contract manufacturers to
produce a number of subassemblies. Utilization of sub-contract manufacturers
results in dependence on the timely delivery of high quality products from
these manufacturers and may leave the Company with less flexibility and
control over the manufacturing process than if it conducted all of these
operations internally. There can be no assurance that the timely delivery of
quality subassemblies will not be interrupted. Any interruption in the timely
supply of quality subassemblies would have a material adverse effect on the
Company's ability to deliver its products until acceptable arrangements could
be made with a qualified alternative subassembly manufacturer. There can be no
assurance that the Company would be able to reach an
 
                                       8
<PAGE>
 
arrangement with such a manufacturer at acceptable prices and adequate quality
levels on a timely basis. If the Company were unable to do so, such an
interruption would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business--Manufacturing."
 
DEPENDENCE ON AVAILABILITY OF COMPONENTS
 
  The Company's 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. There
can be no assurance that such components will continue to be produced.
Further, a number of components contained in the Company's products are single
sourced. While the Company believes that there are other companies that could
provide these components, changing suppliers can create uncertainty and be
costly and time-consuming. In the event that the Company could not obtain
adequate or timely quantities of necessary components from its current
suppliers, there can be no assurance that the Company would be able to
identify or access alternative sources of such components within a reasonable
period of time, on acceptable terms, or at all. Some of the Company's current
vendors use tools that have been designed for and are the property of the
Company; if the Company were required to change suppliers for these
components, it would need either to move the necessary tools or to obtain new
tools, either of which could entail significant cost and delay. Moreover, the
Company's buying power may be limited by its small size, and the Company may
receive less favorable allocations and other terms such as price, timing or
other factors than larger companies buying from the same suppliers. The
unavailability of adequate quantities, the inability to develop alternative
sources, a reduction or interruption in supply or a significant increase in
the price of components could have a material adverse effect on the Company's
ability to manufacture and market its products. See "Business--Manufacturing."
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
  The Company's operating results may vary significantly from quarter to
quarter due to such factors as changes in customer buying patterns, the timing
of the announcement and introduction of new products by the Company or its
competitors, the tactics of the Company's competitors, technological
developments affecting the rugged computing platform market, and the overall
strength of the economy. The Company has experienced some seasonality in
orders for its products, with relatively fewer orders received in the first
quarter of the year, a decline in European orders in the summer, and a rise in
orders in the last quarter. In addition, the Company has experienced long
sales cycles in connection with sales to many of its customers, especially
those that are government agencies or large corporations, and also believes
that such customers may place orders that are disproportionate in size
compared to the Company's other orders. 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 the Company's products, may limit management's
ability to plan for production and to forecast quarterly results of operations
accurately. The Company's operating results for any particular quarter are not
necessarily indicative of results that the Company may achieve for any
subsequent quarter or full fiscal year. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
DEPENDENCE ON INTELLECTUAL PROPERTY
 
  The Company's success will depend in part on its ability to protect its
proprietary rights and to operate without infringing on the proprietary rights
of third parties. As of the date of this Prospectus, no patents have been
issued to the Company. The Company has filed two U.S. patent applications
covering various aspects of its 7000 Series FIELD WORKSTATION laptop computing
platforms and its 5000 Series FIELD WORKSTATION notebook computing platforms
and the technology incorporated in such platforms, and the Company may apply
for additional patents in the future. There can be no assurance that any of
the Company's current or future
 
                                       9
<PAGE>
 
patent applications will result in issued patents, that the scope of the
claims in any patents issued to the Company will prevent competitors from
introducing competitive products or that any patents issued to the Company
would be enforceable if challenged. In addition, even if patents for which the
Company has applied or applies in the future are ultimately issued, other
parties may hold or receive patents that contain claims covering other
technology included in the Company's current or future products that could
hinder or prevent the sale of the Company's products or require the Company to
obtain licenses to such technology, which might not be available on acceptable
terms or at all.
 
  In addition to patents, the Company intends to rely upon unpatented trade
secrets and know-how and on the expertise of its employees. Although the
Company believes that it has in the past taken, and intends in the future to
take, appropriate steps to protect its unpatented proprietary rights,
including requiring that its employees and third parties granted access to the
Company's proprietary technology enter into confidentiality agreements with
the Company, there can be no assurance that these measures will be sufficient
to protect the Company's rights against third parties. Likewise, there can be
no assurance that others will not independently develop or otherwise acquire
unpatented technologies or products similar or superior to those of the
Company.
 
  The Company claims trademark rights in four marks used in connection with
its products in the United States and filed for registration of such
trademarks in June 1996. The U.S. Patent and Trademark Office (the "PTO") has
not determined the registrability of the trademarks. United States trademark
rights are acquired by use rather than by registration, and there can be no
assurance that others do not have conflicting or superior rights to the
Company's trademarks. The Company is aware that there are third parties that
have claimed or may claim superior rights, in certain territories in the
United States, to the use of certain of the marks in which the Company claims
rights; there can thus be no assurance that no third party will contest the
Company's right to use or register its trademarks. In addition, the PTO can
deny registration to trademarks that it determines are "merely descriptive" or
"generic." There can thus be no assurance that any of the trademarks covered
by the Company's applications for registration will be found registrable, that
registrations will issue, or that the Company can support the cost of defense
of its trademarks.
 
  The Company licenses from third parties certain software that it includes in
its products. If any such licenses were terminated, the Company could be
required to license similar software from other third parties; there can be no
assurance that the Company could do so in a timely fashion, on acceptable
terms, or at all.
 
  The high technology area frequently features disputes over intellectual
property. The Company may in the future be required to defend its intellectual
property rights against infringement, duplication, discovery and
misappropriation by third parties or to defend itself against third-party
claims of infringement. Likewise, disputes may arise in the future with
respect to ownership of technology developed by employees who were previously
employed by other companies. Any such litigation or disputes could result in
substantial costs to, and a diversion of effort by, the Company. An adverse
determination could subject the Company to significant liabilities to third
parties, require the Company to seek licenses from or pay royalties to third
parties or require the Company to develop appropriate alternative technology.
There can be no assurance that any such licenses would be available on
acceptable terms or at all, or that the Company could develop alternate
technology at an acceptable price or at all. Any of these events could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Intellectual Property."
 
NEED TO ATTRACT AND RETAIN KEY PERSONNEL
 
  The success of the Company is dependent on its ability to attract and retain
personnel needed for its business. The Company's personnel needs include
highly trained personnel for such areas as management, sales and engineering,
including Gary J. Beeman and Robert C. Szymborski, the Company's co-founders
and currently the President and Chief Executive
 
                                      10
<PAGE>
 
Officer, and Executive Vice President and Chief Technical Officer,
respectively, of the Company. Qualified individuals in such areas are in high
demand and are often subject to competing employment opportunities. In
addition, as the Company increases its production and sales levels, it will
need to attract and retain additional qualified skilled and unskilled workers
for its manufacturing and related operations. In recent years there has been
great demand for qualified skilled and unskilled employees in the Minneapolis
area, where the Company's manufacturing operations are located. There can be
no assurance that the Company will be successful in attracting and retaining
the personnel needed for its business. Any failure to do so would adversely
affect the Company's business, financial condition and results of operations.
See "Business--Employees."
 
RISKS ASSOCIATED WITH INTERNATIONAL SALES
 
  In the nine months ended September 30, 1996, international sales of the
Company's products represented approximately 23% of the Company's 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, potentially adverse tax
consequences, potentially inadequate protection of intellectual property
rights, restrictions on repatriation of earnings, and exposure to increased
political and economic instability. In addition, the Company's net receipts
from international sales are typically lower than net receipts from domestic
sales as the result of the Company bearing some of the cost of foreign import
tariffs and the time required to collect foreign sales receivables is
generally longer than that required for domestic receivables. The loss of a
key foreign distributor or the inability to maintain a foreign distribution
network could have an adverse effect on the Company's business, financial
condition and results of operations.
 
  All of the Company's 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 the Company's products more expensive and,
therefore, potentially less competitive in foreign markets. In the future, if
the Company's export sales were to be denominated in local currencies, foreign
currency translations may contribute to significant fluctuations in the
Company's financial condition and results of operations. If for any reason
currency exchange or price controls or other restrictions on foreign
currencies were imposed, the Company's business, financial condition and
results of operations could be materially adversely affected. See "Business--
Markets and Customers" and "--Sales and Marketing."
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING
 
  The Company anticipates that the net proceeds of this offering, together
with cash on hand, interest expected to be earned thereon and anticipated cash
from operations will be sufficient to finance the Company's operations at
least through 1997, although there can be no assurance that additional capital
will not be required sooner. In order to meet its needs beyond such time, the
Company may be required to raise additional capital. There can be no assurance
that sufficient capital will be available if and when required on terms
acceptable to the Company, if at all. Any additional equity financings may be
dilutive to purchasers in this offering, and any debt financing may involve
restrictive covenants. Failure to secure additional financing if and when
needed could adversely affect the Company and its operations, including
requiring the Company to delay, scale back, or eliminate market expansion
activities and research and development on existing or new products, or
forcing the Company to cease operations entirely. See "Use of Proceeds" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
NO PRIOR PUBLIC MARKET FOR COMMON STOCK; DETERMINATION OF OFFERING PRICE
 
  Prior to this offering there has been no public market for the Common Stock.
Consequently, the initial public offering price of the Common Stock has been
determined by
 
                                      11
<PAGE>
 
negotiations between the Company and the Underwriter and may bear no relation
to the market prices for the shares that will prevail in the public market
following this offering. The Common Stock has been approved for quotation on
The Nasdaq National Market; there can, however, be no assurance that an active
trading market in the Common Stock will develop or be sustained upon
completion of this offering or that the market price of the Common Stock will
not decline below the initial public offering price. For factors considered in
determining the initial public offering price, see "Underwriting."
 
POSSIBLE STOCK PRICE VOLATILITY
 
  The trading prices of the Common Stock could be subject to wide fluctuations
in response to a variety of events or factors, many of which are beyond the
Company's control. These could include, without limitation (i) quarterly
variations in the Company's operating results, (ii) the liquidity of the
market for the Common Stock, (iii) announcements of business developments by
the Company or its competitors, (iv) developments or disputes concerning
proprietary rights, (v) technological innovations or newly introduced
products, and (vi) general conditions in the computer industry and the
economy. Moreover, the stock markets recently have experienced extreme price
and volume fluctuations, which have particularly affected the market prices of
many high technology companies and which have often been unrelated to the
operating performance of such companies.
 
CONTROL BY PRINCIPAL SHAREHOLDERS; ANTI-TAKEOVER PROVISIONS
 
  Upon completion of this offering, the Company's directors and executive
officers and persons or entities affiliated with them will beneficially own in
the aggregate approximately 41% of the Company's outstanding Common Stock
(assuming the exercise of certain shares subject to outstanding options and
warrants). If these shareholders vote together as a group, they will be able
to substantially influence the business and affairs of the Company, including
the election of individuals to the Company's Board of Directors (the "Board of
Directors"), and to otherwise affect the outcome of certain actions that
require shareholder approval, including the adoption of amendments to the
Company's articles of incorporation and certain mergers, sales of assets and
other business acquisitions or dispositions. See "Principal Shareholders."
 
  Upon completion of this offering, the Company will be authorized to issue
five million shares of undesignated preferred stock, $.001 par value, which
may be issued by the Board of Directors on such terms, and with such rights,
preferences and designations, as the Board of Directors may determine, without
further shareholder action. The rights of the holders of the Common Stock will
be subject to, and may be adversely affected by, the rights of any holders of
any preferred stock so issued. In addition, the Company is subject to certain
provisions of the Minnesota Business Corporation Act that limit the voting
rights of shares acquired in certain acquisitions and restrict certain
business combinations. Exercise of voting control by principal shareholders,
the existence or issuance of "blank check" preferred stock and the effect of
other anti-takeover provisions in the Company's charter documents or Minnesota
law, individually or in the aggregate, may render more difficult or discourage
any attempt to obtain control of the Company by means of a tender offer,
merger, proxy contest or otherwise, which could deprive the Company's
shareholders of opportunities to sell their shares of Common Stock at prices
higher than prevailing market prices. See "Description of Capital Stock--
Preferred Stock" and "--Provisions of the Company's Articles and Bylaws and
the Minnesota Business Corporation Act."
 
POSSIBLE ADVERSE MARKET EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE;
REGISTRATION RIGHTS
 
  Sales of significant amounts of Common Stock in the public market or the
perception that such sales will occur could adversely affect the market price
of the Common Stock or the future ability of the Company to raise capital
through an offering of its equity securities. Upon completion of this
offering, the Company will have outstanding 8,047,403 shares of Common
 
                                      12
<PAGE>
 
Stock (or 8,309,903 shares if the Underwriter's over-allotment option is
exercised in full). Of those shares, 1,750,000 shares (or 2,012,500 shares if
the Underwriter's over-allotment option is exercised in full) will be eligible
for immediate sale in the public market without restriction unless they are
held by "affiliates" of the Company within the meaning of Rule 144 of the
Securities Act of 1933, as amended (the "Securities Act"). The remaining
6,297,403 shares of Common Stock will be "restricted securities," as that term
is defined in Rule 144 under the Securities Act, and may be sold in the public
market only if registered or if they qualify for an exemption from
registration under Rule 144, Rule 144(k), Rule 701 or otherwise. The
Representative has requested, and the Company has agreed, to solicit all
shareholders to agree that they will not sell, directly or indirectly, any
Common Stock without the prior consent of the Representative for a period of
180 days from the date of this Prospectus. Of the shares not subject to this
agreement, (i) approximately     shares will be eligible for immediate sale
without restriction pursuant to Rule 144(k) on the effective date of this
offering, (ii) approximately     shares will be eligible for sale, subject to
compliance with the volume limitations and other restrictions of Rule 144, 90
days after the effective date of this offering, and (iii) approximately
shares will become eligible for sale under Rule 144 after the expiration of
the two-year holding periods from the dates of acquisition, which end between
    and    . Beginning on the 181st day after the date of this Prospectus,
when the agreements not to sell shares expire, (iv) approximately 2,519,000 of
the shares may become eligible for sale without restriction pursuant to Rule
144(k), (v) approximately 2,982,637 of the shares (including approximately
2,140,902 shares owned by affiliates of the Company) will become eligible for
sale, subject to compliance with the volume limitations and other restrictions
of Rule 144, and (vi) approximately 795,766 shares will become eligible for
sale under Rule 144 after the expiration of the two-year holding periods from
the dates of acquisition, which end between September 11, 1997 and July 15,
1998. In addition, certain shareholders and holders of warrants, options and
convertible promissory notes, who in the aggregate beneficially own 1,143,634
shares of Common Stock, have the right, subject to certain conditions, to
include their shares in future registration statements relating to the
Company's securities and to cause the Company to register for public sale
certain Common Stock owned by them. See "Shares Eligible for Future Sale" and
"Underwriting."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
  Purchasers of the Common Stock offered hereby will experience immediate and
substantial dilution in net tangible book value per share of $6.85 (assuming
an initial public offering price of $9.00 per share). Investors may also
experience additional dilution as a result of the exercise of outstanding
stock options and warrants. See "Dilution."
 
NO DIVIDENDS
 
  The Company has never paid or declared a cash dividend on its capital stock
and does not anticipate doing so for the foreseeable future. See "Dividend
Policy."

                                USE OF PROCEEDS
 
  The net cash proceeds to the Company from the sale of the Common Stock
offered hereby are estimated to be approximately $13,962,500 ($16,112,375 if
the Underwriter's over-allotment option is exercised in full), after deducting
the underwriting discount and estimated expenses of this offering, and
assuming an initial public offering price of $9.00 per share. The Company
intends to apply such net proceeds substantially as follows:

</TABLE>
 
  REPAYMENT OF CONVERTIBLE BRIDGE NOTES. Approximately $5,104,000 of the net
proceeds will be used to pay principal and accrued interest on the Company's
subordinated promissory notes issued in December 1996, assuming none of such
notes are converted into Common Stock. If some or all of such notes are
converted, the net proceeds that would have been used to repay such notes will
be used for general working capital purposes. The outstanding principal and
accrued interest on such notes will be due and payable within 30 days after
the date of this Prospectus and bear interest at the rate of 10% per annum. Up
to 20% of the principal amount of such notes is convertible for a period of 30
days after the date of this Prospectus, at the option of the holder thereof,
into the Company's Common Stock at a conversion price of 80% of the Price to
Public in this offering. The proceeds from such notes were used to pay off
approximately $2,030,000 outstanding under bank lines of credit that were
personally guaranteed by a director of the Company, and for general working
capital purposes. See "Description of Capital Stock--Bridge Loans."
 
  EXPANSION OF DOMESTIC AND INTERNATIONAL SALES AND MARKETING EFFORTS.
Approximately $2,200,000 of the net proceeds will be used to hire additional
sales and marketing personnel, including district sales managers for strategic
U.S. locations; sales engineers; vertical marketing specialists; and product
management personnel. In addition, the Company anticipates that increased
sales volume will lead to an increase in sales commissions and incentive
compensation.
 
  REPAYMENT OF BRIDGE NOTES. The Company entered into a series of transactions
from July through September 1996 resulting in unsecured loans of which
approximately $1,420,000 in principal and accrued interest is currently
outstanding. Of this amount, approximately $1,314,000 of principal and accrued
interest is due to affiliates of the Company. These loans bear interest at
rates from 10% to 12% per annum. The proceeds from the short-term loans were
used for general working capital purposes. See "Certain Transactions" and
"Description of Capital Stock--Bridge Loans."
 
  CAPITAL EXPENDITURES. The Company intends to spend approximately $1,000,000
in 1997 on capital expenditures, including the procurement of injection
molding tools for the production of the 5000 Series chassis and for leasehold
improvements to the expanded facilities that the Company anticipates requiring
in mid-1997.
 
  WORKING CAPITAL AND GENERAL CORPORATE PURPOSES. The remainder of the net
proceeds, approximately $3,738,500 will be allocated to working capital and
will be used for purposes including the addition of manufacturing and
administrative infrastructure to support expansion.
 
  In addition, the Company may also use a portion of the net proceeds to
acquire businesses, products or technologies that management believes may
complement the Company's operations, although the Company currently has no
agreements or understandings regarding any such acquisition and is not
involved in any negotiations with respect to any such transactions.
 
                                      14
<PAGE>
 
  The amounts given above are estimates, and the amount and timing of actual
expenditures will depend on numerous factors, including competition,
manufacturing activities and the level of market acceptance of the Company's
products.
 
  Pending the use of the net proceeds of this offering, the Company will
invest the funds in short-term, interest-bearing, investment grade securities.
 
  The Company believes that the proceeds of this offering, together with cash
on hand, interest expected to be earned thereon, and anticipated revenues will
be sufficient to fund its operations at least through 1997. In order to meet
its needs beyond such time, the Company may be required to raise additional
capital. There an be no assurance that sufficient capital will be available if
and when required on terms acceptable to the Company, if at all. See "Risk
Factors--Future Capital Needs; Uncertainty of Additional Funding."
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid any cash dividends on its capital
stock. The Company currently intends to retain all of its earnings, if any, to
finance the development and continued expansion of its business, and does not
intend to pay dividends in the foreseeable future. The payment of dividends,
if any, in the future will be at the discretion of the Board of Directors and
will depend on the Company's earnings, financial condition, capital
requirements, and other relevant factors.
 
  In November 1996, the Company's Board of Directors approved the distribution
of all of the issued and outstanding shares of the capital stock of a wholly-
owned subsidiary as a dividend to shareholders of record as of November 15,
1996. See "Recent Events--Dividend of Shares of Paragon Technology, Inc."

                                   DILUTION
 
  Pro forma net tangible book value per share represents total assets, less
total liabilities, divided by the number of shares outstanding as of September
30, 1996 (adjusted to reflect the conversion of the Preferred Stock into
Common Stock upon the consummation of this offering). The Company's pro forma
net tangible book value as of September 30, 1996, was approximately
$3,692,000, or approximately $0.59 per share. Without taking into account any
changes in such net tangible book value per share after September 30, 1996,
other than to give effect to the sale of the shares of Common Stock offered
hereby at an assumed initial public offering price of $9.00 per share and the
receipt of the net proceeds of such sale, the pro forma net tangible book
value per share as of September 30, 1996, would have been approximately
$17,263,000, or approximately $2.15 per share. This represents an immediate
increase in net tangible book value per share of $1.56 to existing
shareholders and an immediate dilution of $6.85 per share to new investors.
The following table sets forth this per share dilution:

  The above calculations do not give effect to the possible issuance of (i)
724,500 shares of Common Stock issuable upon exercise of options outstanding

share, (ii) 588,078 shares of Common Stock issuable upon exercise of warrants
outstanding (as of December 20, 1996) at a weighted average exercise price of
$5.28 per share and (iii) up to 138,889 shares of Common Stock issuable within
30 days of the effective date of the registration statement of which this
Prospectus is a part upon conversion (at a conversion price equal to 80% of an
assumed initial public offering price of $9.00) of up to $1,000,000 of the
principal amount of certain outstanding Promissory Notes. To the extent that
these options, warrants and conversion rights become exercisable and are
exercised or to the extent additional options or warrants are granted or
exercised, there will be further dilution to new investors. See "Description

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Consolidated
Financial Statements and Notes thereto included elsewhere in this Prospectus.
This Prospectus contains, in addition to historical information, forward-
looking statements that involve risks and uncertainties. The Company's actual
results could differ materially from the results discussed in the forward-
looking statements. Factors that could cause or contribute to such differences
include those discussed below, as well as those discussed elsewhere in this
Prospectus. See "Risk Factors."
 
GENERAL
 
  FieldWorks was incorporated in 1992 to provide rugged computing platforms
and computer system solutions for use by field personnel. From its inception
through June 1994, the Company's activities consisted primarily of developing
its products and building its infrastructure. The Company shipped its first
commercial product, the 7000 Series FIELD WORKSTATION rugged laptop computing
platforms, in June 1994, and the 5000 Series FIELD WORKSTATION rugged notebook
computing platforms in June 1996.
 
  The Company recognizes revenue upon shipment of product. Although the
Company's revenues have increased in each of the last seven quarters, the
Company has incurred net losses in six of the seven quarters and had an
accumulated deficit of $4.4 million as of September 30, 1996. The Company's
limited operating history makes the prediction of future operating results
difficult. Accordingly, although the Company has experienced revenue growth,
such growth should not be considered indicative of future revenue growth, if
any, or of future operating results. See "Risk Factors--Limited Operating
History; History of Operating Losses; Uncertainty of Future Profitability" and
"--Fluctuations in Quarterly Operating Results."

COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995
 
  Net Sales. The Company's net sales increased 63% from $5.9 million in the
nine months ended September 30, 1995 to $9.6 million for the nine months ended
September 30, 1996. The increase in net sales was due primarily to an increase
in the number of units sold and also to an increase in the average selling
prices of the 7000 Series driven by the levels of optional features included
in units sold, such as Pentium chips, RAM memory and CD-ROM drive upgrades,
enhanced wet and cold weather packages, and electromagnetic emission control
packages, as well as peripheral equipment purchases such as batteries and
carrying cases. International sales decreased from 38% of net sales in the
nine months ended September 30, 1995, to 23% of net sales in the nine months
ended September 30, 1996, as a result of the Company's focus on building its
domestic sales force and testing to demonstrate continued compliance with new
European EMI standards following certain changes to the 7000 Series.
 
  Gross Profit. Gross profit increased 48% from $2.5 million in the nine
months ended September 30, 1995, to $3.6 million in the nine months ended
September 30, 1996. As a percentage of net sales, gross profits decreased from
42% in the first nine months of 1995, to 38% in the first nine months of 1996.
This decrease in gross profit as a percentage of net sales was the result of
reduced efficiencies related to bringing the 5000 Series into full production
and of increased sales of the lower-margin 5000 Series.
 
  Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, bonuses and commissions, promotions and advertising and travel.
Sales and marketing expenses increased from $1.1 million or 18% of net sales
for the nine months ended September 30, 1995, to $2.2 million or 23% of net
sales for the same period in 1996, primarily due to increased advertising,
staffing and promotion expenses, all of which were intended to build general
product recognition and to introduce the 5000 Series. The Company expects that
its sales and marketing expenses will continue to increase as it seeks to
expand its sales channels.
 
  General and Administrative. General and administrative expenses consist
primarily of salaries, professional services, facilities, incentive
compensation and bad debt costs. General and administrative expenses increased
from $0.8 million or 13% of net sales for the nine months ended September 30,
1995, to $1.5 million or 15% of net sales for the same period in 1996, due
primarily to increased staffing, legal fees and facilities expenses. The
Company expects to continue to increase its general and administrative
expenses in the foreseeable future as it adds general and administrative
infrastructure.
 
  Research and Development. Research and development expenses consist
primarily of salary and materials costs incurred in the development and
testing of new products and customized platforms. Research and development
costs are expensed as incurred. Research and development expenses increased
from $0.6 million or 10% of net sales for the nine months ended September 30,
1995, to $1.0 million or 11% of sales for the same period in 1996. The
increase in research and development expenses was primarily due to significant
investment in the 5000 Series and also to continued development of the 7000
Series. The Company expects research and development expenses to increase for
the foreseeable future.
 
  Interest Expense and Other, Net. Interest expense increased from
approximately $52,000 for the nine months ended September 30, 1995 to $223,000
for the same period in 1996, primarily due to higher levels of indebtedness,
both under the Company's bank line of credit and in the form of loans
primarily from affiliated parties, that were required to fund working capital
requirements. See "--Liquidity and Capital Resources."
 
COMPARISON OF YEARS ENDED DECEMBER 31, 1993, 1994, AND 1995
 
  Net Sales. Net sales increased 201% from $2.7 million in 1994, the Company's
first year of commercial sales, to $8.2 million in 1995. This increase was due
primarily to an increase in
 
                                      20
<PAGE>
 
the number of units sold partially offset by a 6% decrease in the average
selling prices for the 7000 Series. Sales to the Company's international
distributors accounted for 39% and 35% of net sales for 1994 and 1995,
respectively.
 
  Gross Profit. Gross profit increased 327% from $0.8 million in 1994 to $3.3
million in 1995. As a percentage of net sales, gross profit increased from 28%
in 1994 to 40% in 1995. This increase in gross profit was the result of
improved economies of scale realized from increases in production volume and
also of enhanced manufacturing and procurement efficiencies.
 
  Sales and Marketing. There were no significant marketing and selling
expenses in 1993. Sales and marketing expenses increased from $0.9 million or
33% of net sales for 1994 to $1.5 million or 18% of net sales for 1995,
primarily as the result of increased expenditures in advertising, promotion
and staffing. Sales and marketing expenses as a percentage of sales decreased
due to increased market acceptance of the Company's products.
 
  General and Administrative. General and administrative expenses increased
from $0.2 million in 1993 (on no net sales) to $0.8 million or 28% of net
sales in 1994 and to $1.2 million or 14% of net sales in 1995. The increases
from 1993 to 1994 were the result of administrative staffing increases,
facility growth and infrastructure development. Increases in 1995 resulted
from a move to a new facility, the addition of staff and an increase in
professional service expenses.
 
  Research and Development. Research and development expenses increased from
$0.3 million in 1993 (on no net sales) to $0.8 million or 28% of net sales in
1994 and to $0.9 million or 12% of net sales in 1995. These increases were the
result of the Company's efforts to build and support its engineering
infrastructure related to development of the 7000 Series. In addition, the
Company's research and development costs increased in the second half of 1995
as the result of efforts related to the development of the 5000 Series.
 
  Interest Expense and Other, Net. Interest expense increased from $21,000 in
1994 to $69,000 for 1995, primarily due to increased line of credit borrowings
to fund additional working capital requirements. The Company had no borrowings
outstanding in 1993.
 
QUARTERLY RESULTS OF OPERATIONS
 
  The following table sets forth certain unaudited financial data for each of
the seven consecutive quarters ended September 30, 1996. This data has been
derived from unaudited consolidated financial statements that, in the opinion
of management, include all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of such information. Such
statement of operations data should be read in conjunction with the Company's
audited Consolidated Financial Statements and Notes thereto.
 
  The Company's operating results may vary significantly from quarter to
quarter due to a wide range of factors, such as changes in customer buying
patterns, the timing of the announcement and introduction of new products by
the Company or its competitors, the tactics of the Company's competitors,
technological developments affecting the rugged computing platform market, and
the overall strength of the economy. As a result, the Company's operating
results for any particular quarter are not necessarily indicative of results
that the Company may achieve for any subsequent quarter or full fiscal year.
See "Risk Factors--Fluctuations in Quarterly Operating Results."

LIQUIDITY AND CAPITAL RESOURCES
 
  Since inception, the Company has principally financed its operations and
capital expenditures through the private sale of equity securities, generating
net proceeds of $7.9 million as of September 30, 1996; through bank lines of
credit, of which $2.0 million was outstanding as of such date; and September
30, 1996 outstanding loans of $1.4 million, of which $1.3 million were with
affiliated parties.
 
  As of September 30, 1996 the Company had cash of $0.3 million.
 
                                      22
<PAGE>
 
  On December 18 and 19, 1996, the Company issued an aggregate of $5,000,000
original principal amount of subordinated promissory notes. These notes,
together with interest thereon, are due on June 30, 1997; provided, that the
Company may extend their final maturity to December 31, 1997, by written
notice delivered to holders at any time before June 30, 1997; provided,
further, that these notes shall be payable in full within thirty (30) days
after the effective date of the registration statement of which this
Prospectus forms a part. The Company used approximately $2,030,000 of the
funds borrowed to repay amounts outstanding under bank lines of credit (as to
one of which the Company was in default of certain financial covenants as of
September 30, 1996). The Company will utilize the remaining amounts to fund
its operations until the completion of this offering.
 
  Cash used for operating activities totalled $0.4 million in 1993, $2.9
million in 1994, $1.7 million in 1995, and $4.7 million in the nine months
ended September 30, 1996. The Company purchased property and equipment of $0.1
million in 1993, $0.3 million in 1994, $0.2 million in 1995, and $0.4 million
in the first nine months of 1996.
 
  The Company believes that the proceeds of this offering, together with cash
on hand, interest expected to be earned thereon, and anticipated revenues will
be sufficient to fund its operations at least through 1997. In order to meet
its needs beyond such time, the Company may be required to raise additional
capital. There can be no assurance that sufficient capital will be available
if and when required on terms acceptable to the Company, if at all. See "Risk
Factors--Future Capital Needs; Uncertainty of Additional Funding."

                                 RECENT EVENTS
 
  During the first half of 1996, the Company began shipping demonstration
units of its 5000 Series FIELD WORKSTATION for customer test trials.
Complexities in engineering development delayed the shift from production of
demonstration units to commercial production of the 5000 Series beyond the
time that the Company had initially anticipated. The Company began shipping
commercial production units of the 5000 Series in June 1996, and has increased
the number of units shipped in each month since then. However, strong early
customer response caused a significant increase in total order bookings in the
third quarter of 1996, as shown in the following table:

  In light of the time necessary to introduce full-scale commercial production
of the 5000 Series, this large volume of orders contributed to a September 30,
1996, backlog of approximately $2.8 million (of which approximately $0.7
million represented orders deliverable in 1997). See "Business--Backlog." The
Company expects to be able to fill approximately $1.8 million of this backlog
before the end of 1996 and believes that custom orders requiring a longer
fulfillment time will represent the bulk of the September 30, 1996, backlog
orders not filled by the end of 1996. Further, the Company currently
anticipates that by the end of the first quarter of 1997 it will have filled
all current backlog orders and will have reduced its average fulfillment time
to its goal of four weeks. There can, however, be no assurance that the
Company will be able to do so; for factors that might prevent this, see "Risk
Factors--Risks Associated with Managing Growth."
 
  The delay in the commercial introduction of the 5000 Series, together with
expenses incurred by the Company in connection with building its corporate
infrastructure to support the anticipated volume of sales of the 5000 Series,
has adversely affected the Company's profits in the second half of 1996.
 
DIVIDEND OF SHARES OF PARAGON TECHNOLOGY, INC.
 
  In August 1995 the Company acquired a wholly-owned subsidiary, Paragon
Technology, Inc. ("Paragon"), which designs and sells high performance
graphics subsystems for the commercial and OEM markets, including MPEG-II
video compression decoding solutions, image manipulation software and digital
video disk ("DVD") technology. The Company incorporates certain of Paragon's
technology in its computing platforms. Paragon also licenses its products to
large personal computer manufacturers, which include the Paragon products in
commercially available personal computers. In November 1996, the Company's
Board of Directors approved the distribution of all of the issued and
outstanding shares of Paragon's capital stock as a dividend to shareholders of
record of the Company as of November 15, 1996. The Company anticipates that
the distribution of this dividend will be completed before December 31, 1996.
Until December 31, 1996, the Company will provide working capital for Paragon;
from November 15, 1996, until such date, the Company estimates that such
working capital contributions may aggregate between $50,000 and $100,000.
Following completion of the dividend: (i) two of the Company's directors and
officers, Gary Beeman and Robert Szymborski, will serve as directors of
Paragon, (ii) Mr. Beeman will serve as Paragon's Chairman of the Board and
(iii) the Company and Paragon intend to enter into strategic relationships in
the areas of product development and marketing. Since the record date for the
dividend was November 15, 1996, purchasers of shares of Common Stock in this
offering will not be entitled to receive any Paragon stock, nor to receive any
other property in lieu of such dividend.

                                   BUSINESS
 
THE COMPANY
 
  FieldWorks designs, manufactures, markets and supports portable rugged
computing platforms and computer system solutions for use in demanding field
environments. In addition to providing the full range of computer features,
performance and functionality typically found in high-end desktop computers,
the Company's portable computing platforms have been designed to meet rigorous
military standards for ruggedness and to function despite exposure to extreme
temperature, mechanical shock, vibration and moisture. The Company's computing
platforms are expandable through multiple expansion slots to provide a
flexible electronic "toolbox" that can integrate all of a user's application-
specific, multi-media and communications needs into one portable, rugged
device. The Company's products have been designed with a modular system
configuration that allows a user to easily upgrade the central processing unit
("CPU") processor or any of the other technological components without
purchasing a new computer. Further, the Company has the ability to customize
its computing platforms to meet the unique needs of its customers.
 
  The Company targets those markets that require portable computing platforms
that can perform multiple functions, including diagnostics, data acquisition
and electronic testing and monitoring, and simultaneously provide
communications and computer capability even under adverse conditions in the
field. FieldWorks rugged computing platforms are in use in a variety of market
applications, including: electronic toolboxes for telecommunications test
crews to simplify and expedite installation, repair and troubleshooting tasks;
data collection and transmission for in-flight commercial airplane testing;
collection and analysis of Global Positioning System ("GPS") geographical
information and agricultural data to aid in the selection of crops, chemicals
and farming methods; diagnostic system analysis and wireless communication for
use with trucking fleets; and video surveillance and monitoring for law
enforcement purposes. The Company believes that its rugged computing
technology has enabled its customers to create new applications that improve
the productivity of their field personnel and believes further that additional
markets and customers will develop as more businesses recognize the benefits
of providing field personnel with effective, sophisticated computing power.
 
  The Company markets its products worldwide through a direct sales force,
independent sales representatives and distributors, OEMs, VARs and systems
integrators. The Company's ten top customers during the twenty-one months
ended September 30, 1996 were The Freightliner Corporation ("Freightliner"),
Liberty Technologies, Inc. ("Liberty"), Texas Instruments Incorporated ("Texas
Instruments"), Keithley Metrabyte, a division of Keithley Instruments Inc.,
Dateppli Inc. (for sale to Ford Motor Company), Strategic Solutions, Inc., JoR
A.B. (for sale to L.M. Ericsson A.B., Sweden), International Atomic Energy
Agency, AT&T Corporation and Pacific Avionics, Inc. In July 1996, one of the
Company's customers, Network General, entered into an agreement with the
Company pursuant to which Network General made a $3 million equity investment
in the Company.
 
FIELD COMPUTING MARKET
 
  Due to rapid technological advances over the past several years,
organizations have become increasingly dependent on mobile computing and
communications devices, such as portable computers, pagers and cellular
telephones, to enhance workforce productivity. Highlighting this trend is the
growth in the market for consumer portable computers, which Frost & Sullivan
has predicted may reach annual worldwide sales of nearly $80 billion by 2001.
Although this demand has to date been largely attributable to offices and
office staff, organizations are increasingly seeking to computerize field
personnel, in particular those who (i) have direct contact with customers,
(ii) install, diagnose and maintain company or customer equipment, or (iii)
collect the critical information that allows the business to better meet the
needs of its customers. Such computerization can provide sophisticated field
diagnostic and analytic capabilities, enhance field access to data and on-line
information, eliminate paperwork
 
                                      25
<PAGE>
 
and improve electronic dispatching and communication. As a result, the market
for mobile computing and field force automation products is predicted to be
one of the fastest growing sectors of the computer industry through 1999, with
annual growth predicted at as much as 35% or more. According to International
Data Corp. ("IDC") estimates, the rugged portable computer market is currently
over $500 million and is expected to grow by more than 50% over the next three
years.
 
  Industries such as telecommunications, utilities, farming, law enforcement,
the military and transportation have recognized the need for computerization
and automation in the field. However, the effectiveness of field force
computerization and automation efforts has often been limited by the nature of
the products that have been available. Computers are now being used in the
field to perform a wide range of tasks, but both off the shelf, consumer
portable computers and custom-designed portable computers generally have
significant shortcomings that limit their use by field personnel. In part as a
result of these limitations, some companies still prefer to employ only
single-purpose diagnostic and data collection machines in the field, foregoing
the benefits of full computerization.
 
  Consumer portable personal computers that are designed for office or home
use frequently become inoperable under the harsher conditions present in the
field. The chart below illustrates the durability problems encountered when
attempting to use a consumer personal computer in the field.
 
[This graph shows the percentage of buyers reporting types of damage for the
following events:
 
     Accidental drops/pavement:
            Damage has happened: approximately 62%
            Damage rendered computer inoperable: approximately 52%
     Food/liquid spills:
            Damage has happened: approximately 45%
            Damage rendered computer inoperable: approximately 23%
     Dirt/other contamination:

            Damage rendered computer inoperable: approximately 14%]
 
     (1) Based on a random survey of 589 InfoWorld subscribers
         involved in purchasing portable personal computers. Damage
         as reported is not representative of damage per single
         computer or over any particular time period, and should
         not be deemed to represent the likelihood that any
         particular computer will be damaged over any particular
         time period.
 
Frost & Sullivan has reported that in one survey it conducted, respondents
reported that between 20% and 25% of all notebook computers used were sent in
for repairs each year, with average "down time" of five and one-half days per
computer. The frequent repair necessary for typical consumer portable
computers that are used in the field results not only in the cost of repair
itself, but also in the lost productivity and associated expense caused by
repair down time.
 
  In addition, consumer portable personal computers are typically available
only with a standard set of features that cannot be expanded or customized to
meet the unique requirements of field personnel. For example, field
technicians require diagnostic and data collection capabilities in addition to
typical office environment computer functionality. Thus, standard portable
personal computers' lack of expandability limits their usefulness as complete
electronic toolboxes for field personnel.
 
  Further, consumer portable personal computers generally are not designed to
be upgraded. Rapidly changing technology results in frequent changes in the
availability of portable personal computers as models change. Large
organizations can discover that their attempts to deploy effective and
consistent field force computerization over a period of time are impaired when
they are unable to continue to purchase the same models of portable personal
computers or when the computers become outmoded.
 
                                      26
<PAGE>
 
  The alternatives to off the shelf, fragile, non-expandable, portable
personal computers have been either custom-designed personal computers or
mobile single-purpose diagnostic and data collection instruments. While
custom-designed portable personal computers can be configured to serve
specific field uses, they are expensive, generally limited in their
applications and often unable to withstand conditions typically present in the
field. Mobile single-purpose diagnostic and data collection instruments are
designed to withstand field conditions, but generally have little independent
computing capability. Data analysis and manipulation, therefore, must be
performed later on a separate, non-portable computer.
 
THE FIELDWORKS SOLUTION
 
  The Company has focused on delivering products that address the varied and
specialized requirements of field force personnel. The Company's products
feature four critical design characteristics that it believes purchasers of
field computing platforms require.
 
  Rugged. The Company's computing platforms have been designed to meet
stringent military standards of ruggedness, and to function despite extreme
temperatures, mechanical shock while operating up to 100 Gs (100 times the
force of gravity), vibration and moisture. The Company achieves this by using,
among other things: (i) high-strength cast magnesium chassis, (ii) special
shock absorbers for internal components, (iii) durable gold-plated
interconnect systems and (iv) rubber sealing.
 
  Expandable. The Company has focused on providing computing platforms that
are expandable to accommodate both current and future needs of the field force
user. The Company's computing platforms allow for the integration of
application-specific equipment, including auxiliary test, measurement and
diagnostic subsystems and multi-media and communications modules. These
expansion capabilities also allow the Company's computing platforms to adapt
to the evolving requirements of the user, whose needs can change as additional
technology is developed in the future.
 
  Upgradeable. The pace of change in technology such as processors, memory and
display methods can rapidly render non-upgradeable computers obsolete. Unlike
typical consumer portable computers, the Company's computing platforms are
designed to be easily upgraded using standard component parts. The modularity
of the Company's computing platforms allows for easy replacement of all major
subsystems, including processors, screens, disk drives, memory and keyboards,
thereby extending useful life and reducing the overall cost of ownership.
 
  Customizable. Many of the Company's customers have unique needs that require
some degree of customization, from the incorporation of unique functions to
the design and production of special purpose machines. The modular design of
the Company's computing platforms allows the Company to readily adapt its
machines to a customer's specifications. Customization has ranged from fairly
simple mechanical adaptations to sophisticated electrical and mechanical
modifications. Examples of customized features have included: (i) designing
modifications to reduce electro-magnetic emissions, (ii) including
particularly delicate magneto-optical disk drives and (iii) incorporating
specialized high performance graphic subsystems to allow full-motion video
applications.
 
STRATEGY
 
  The Company's objective is to be the leading designer, manufacturer and
marketer of rugged computing platforms and computer system solutions. The
Company's strategy consists of the following key components:
 
    Penetrate Key Vertical Markets. The Company is seeking to penetrate key
  vertical markets including military/government, utilities, transportation,
  aviation, telecommunications and law enforcement. The Company intends to
  employ a variety of approaches in these various markets, including building
  strategic OEM relationships and focusing on relationships with
 
                                      27
<PAGE>
 
  large volume repeat customers, depending on the characteristic purchasing
  patterns of each vertical market. Where appropriate, the Company develops
  specialized product features and functions to address the special needs of
  a particular vertical markets.
 
    Expand Strategic OEM Relationships. Certain of the Company's key vertical
  markets are characterized by dominant third party OEMs. In those markets,
  the Company sells its computing platforms to be bundled into computer
  system solutions that the OEMs then sell to end users. Examples of existing
  relationships include an OEM relationship with Texas Instruments, which
  provides surveillance systems for military and law enforcement uses through
  its Phototelesis division; an exclusive OEM supply relationship with
  Liberty, the major producer of testing systems for the nuclear power
  industry; and an OEM relationship with Network General, a major producer of
  telecommunications testing systems.
 
    Establish Relationships with Large-Volume, Repeat Customers. The Company
  intends to focus the efforts of its direct sales force and sales channel
  partners on meeting the ongoing needs of large-volume purchasers. The
  Company believes that its products are particularly attractive to such
  customers given the Company's ability to customize its computing platforms
  for specialized needs and the ease with which the Company's computing
  platforms can be upgraded and standardized throughout an organization. The
  Company believes that its ability to accommodate developing technologies
  addresses the concerns many large organizations have regarding the impact
  of technological obsolescence in the context of large computer equipment
  investments.
 
    Develop New Products and Enhance Existing Products. During the past four
  years the Company has made a substantial investment in developing its
  current computing platform technologies, which it believes have provided it
  with significant expertise with regard to rugged computing platforms. The
  Company intends to leverage this expertise to develop new products and
  enhance existing products. The Company is currently developing additional
  series of computing platforms designed to address broader customer
  preferences for products with varying degrees of expandability, size and
  price, all of which provide users with the ruggedness, processing power and
  ease of upgrade that characterize the Company's current products. The
  Company is also constantly working to add new features and functions to its
  existing products.
 
    Establish Product Recognition. The Company's goal is to establish the
  Company's products as the standard for quality portable rugged computing
  platforms. The Company's approach in this respect was to begin by
  establishing the Company's products and their reputation for quality with
  those customers who demand the greatest number of features. Accordingly,
  the Company initially entered the rugged computing platform market with the
  7000 Series FIELD WORKSTATION rugged laptop computing platform. The Company
  intends to continue to build its reputation in the high-end portion of the
  market while also utilizing its product recognition to penetrate portions
  of the market where customers have different preferences for expandability,
  size and price.
 
CURRENT PRODUCTS
 
  The Company introduced its first commercial product, the 7000 Series FIELD
WORKSTATION rugged laptop computing platform, in June 1994. The 7000 Series,
available in a range of models, offers significant expansion capacity and is
targeted at the high end of the rugged field computing platform market. In
June 1996, the Company commercially introduced its 5000 Series FIELD
WORKSTATION rugged notebook computing platform, which is also offered in a
range of models. This Series is designed to meet the needs of those customers
with uses that require a smaller, more lightweight toolbox but do not require
the same degree of expandability.
 
  The Company's 7000 Series and 5000 Series share many significant design and
performance characteristics. In particular, both series satisfy military
standards for battlefield equipment with respect to shock (up to 100Gs while
operating) and vibration. Both series share a modular design that allows for
ease of upgrading. Both series can be configured with a variety
 
                                      28
<PAGE>
 
of screens, memory capacities up to 128 Megabytes and disk drives up to 2.1
Gigabytes and are available with x486 or Pentium processors, as well as
various networking and communications options. All of the Company's computing
platforms are compatible with DOS, Windows, Unix, OS/2 and other operating
systems and come with a sealed keyboard and a FIELD MOUSEPAD pointing device
that can also serve as a signature and drawing pad.
 
  7000 Series Field WorkStation Rugged Laptop Computing Platform. The
structure of the 7000 Series FIELD WORKSTATION laptop computing platform is
based on a high-strength cast magnesium alloy external housing. Internal
components that are sensitive to shock and vibration are contained within this
housing and isolated with special tuned shock absorbing polymers, while a
shock absorbing bushing system suspends all drives and the CPU. The 7000
Series incorporates the Company's backplane/card cage design, which provides
up to six ISA/PCI expansion card slots within the housing. These slots permit
the integration of instrumentation, data acquisition and communications
capabilities in the computing platform. Also contained within the housing are
PCMCIA expansion capability, integrated AC/DC power, battery capability,
desktop ISA/PCI slots, optional integrated CD-ROM, optional dual removable
hard drive system and optional Motion Picture Experts Group ("MPEG-II") video
compression decoding boards. The units in the 7000 Series weigh approximately
14 1/2 pounds.
 
  5000 Series Field WorkStation Rugged Notebook Computing Platform. The
structure of the 5000 Series FIELD WORKSTATION rugged notebook computing
platform is based on an internal frame cast from a high-strength magnesium
alloy, and is encased in a specially-developed urethane coating. The skeleton
and coating protect internal sub-systems from shock and vibration. In
addition, some of the internal subsystems are suspended by a shock absorbent
bushing system. Virtually all of the electronics of the 5000 Series are
contained in a "technology module" that has been designed for easy removal,
making it possible for customers to service the units themselves and
simplifying upgrades. In addition to two optional ISA or PCI expansion slots,
all computing platforms in the 5000 Series have four universal bays in two
sizes. The two larger bays can house batteries, CD-ROM drives, an internal AC
adapter, hard drives or floppy drives. The two smaller bays can house
removable drives and/or PCMCIA slots. 5000 Series units weigh approximately 10
1/2 pounds.
 
  The Company does not currently maintain an inventory of assembled computer
platforms; instead, it assembles its products to its customers' specifications
as orders are received. This enables the Company to provide each customer with
a computing platform that satisfies the customer's specific requirements.
 
  The Company's 7000 Series FIELD WORKSTATION computing platforms have current
base list prices to end users of approximately $6,000 with standard features.
The Company's 5000 Series FIELD WORKSTATION computing platforms have base list
prices to end users of approximately $5,000 with standard features.
 
MARKETS AND CUSTOMERS
 
  The markets for the Company's products consist of those businesses and other
entities that are seeking effective mobile computing platforms for field
personnel and functions. Users of the Company's field computing platforms and
their demands vary widely, and include: (i) the military, which needs mobile
units capable of withstanding battlefield conditions, (ii) 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, and (iii) field sales
personnel, who need multi-media capabilities in a mobile unit that also
provides networking capabilities. Customers have found a wide variety of
specific uses for the Company's rugged computing platforms in the field, such
as the following examples drawn from some of the Company's target market
segments.
 
  Law Enforcement. A federal law enforcement agency is conducting surveillance
and monitoring using a reconnaissance device that includes a FieldWorks
computing platform. This
 
                                      29
<PAGE>
 
device was employed at the 1996 Summer Olympic Games in Atlanta to capture
digital images and to communicate sensitive information to major intelligence
agencies around the world. Among other functions, the FieldWorks computing
platform provided the expandability necessary to house and control the
device's encryption, digital image capture and satellite communications
subsystems and functions.
 
  Aviation. The Company's computing platform is used for in-flight commercial
airplane testing, where it is connected to the plane's data logging computer
to collect information that is then transmitted to engineers for analysis.
Since the computing platform must operate in areas of the plane that are
sensitive to electro-magnetic interference ("EMI"), the Company's engineers
customized the FieldWorks computing platform to develop an EMI-certified
portable computing platform.
 
  Agriculture. A software developer has integrated the Company's computing
platform into an on-board "precision farming" system that utilizes GPS
technology to collect and analyze geographic information, fertilizer levels,
plant population, yield and other variables present on a specific farm. These
data can then be used to select the most appropriate crops, chemicals and
farming methods. Detachable mounts allow the computing platform to be moved
from one farm vehicle to another or to the home office.
 
  Telecommunications. Test crews use the Company's computing platforms as
electronic toolboxes to simplify and expedite installation, repair and
troubleshooting tasks, such as network testing. The expandability of the
Company's computing platforms allow for the integration of the diagnostic
instrumentation necessary for these tasks.
 
  Transportation. The Company's computing platforms are used in a portable
technical information and diagnostic system for use with fleets of trucks.
Maintenance personnel use the FieldWorks computing platforms incorporated in
this system not only to collect information from each vehicle's electronic
control and data logging units but also to view or graph the information and
to perform on the spot diagnostic routines that utilize the information.

</TABLE>
 
  In the first nine months of 1996, sales to two customers, Freightliner and
Texas Instruments, each accounted for more than 5% of net sales. During the
same period, sales to international customers represented approximately 23% of
net sales. During 1995, sales to Freightliner accounted for more than 5% of
net sales. During the same period, sales to international customers
represented approximately 35% of net sales. The Company does not believe that
it is dependent upon sales to any single customer given the Company's history
of a relatively large number of different customers and wide variations in the
size and timing of orders from both new and repeat customers.
 
  The Company believes that additional markets and customers will continue to
develop as more businesses recognize the benefits of providing field personnel
with effective, sophisticated computing power.
 
                                      31

  The market for portable rugged computing platforms is in the early stages of
its development. There can be no assurance that a substantial market will
develop for the Company's products within the timeframe it anticipates or at
all. See "Risk Factors--Uncertainty of Market Acceptance."
 
SALES AND MARKETING
 
  The Company markets its products worldwide through a direct sales force,
independent sales representatives and distributors, OEMs, VARs and systems
integrators. The Company's sales and marketing efforts are based on the
recognition that each of the Company's target vertical markets purchase from
different channels.
 
  The Company's direct sales force focuses its efforts on building and
maintaining relationships with large-volume, repeat purchasers of the
Company's computing platforms and with entities that the Company considers to
be dominant manufacturers or sales channel entities within their vertical
markets. The Company also utilizes a network of approximately 19 independent
sales representatives for domestic sales. Other segments of the market are
addressed by sales to VARs and systems integrators that typically sell systems
that have been configured for specific end-user applications through the
addition of hardware, software or service. For international sales, the
Company maintains a network of approximately 38 international distributors,
which are managed by the Company's director for international sales. To date,
the Company's international sales have been principally in Europe, the Far
East and Australia, with recent sales in South America and Africa.
 
  As of December 1, 1996, the Company employed 21 people in sales and
marketing. The direct sales effort is managed by a Vice President of Sales,
five regional sales managers within the United States, one director for
federal government sales and one director for international sales. Six of the
employees are engaged principally in marketing efforts and the remaining
persons are engaged primarily in sales. The Company conducts its sales
activities from its headquarters in Minnesota as well as sales offices in
Virginia, New Jersey and Alabama.
 
  The Company advertises its products both in industry-specific trade
publications in the Company's target markets, such as Aviation Week and
Maintenance Technology, and in general interest computer magazines, such as PC
Week and BYTE. In addition, the Company participates in industry trade shows
in the Company's target markets and in computer industry trade shows. For
example, the Company participates in the UTC (Utilities Trade Conference) and
the AFCEA, a government and military trade show, in addition to the COMDEX
fall and spring shows. The Company has also employed direct mail campaigns
aimed at potential customers in its target markets.
 
BACKLOG
 
  The Company's order backlog at September 30, 1996, was approximately
$2,797,000, of which approximately $730,000 represented orders deliverable in
1997 under committed future release dates, compared to approximately $233,000
at September 30, 1995. The Company's sales are made through purchase orders.
Orders are generally shippable within the upcoming quarter unless noted as a
committed future release date order. The Company's goal is to deliver orders
within four weeks of receipt; however, the factors discussed above under
"Recent Events" contributed during the third quarter of 1996 to the creation
of a backlog of orders that currently exceeds the Company's ability to fulfill
orders within such time period. The Company expects to be able to fill
approximately $1.8 million of this backlog before the end of 1996 and believes
that custom orders requiring a longer fulfillment time will represent the bulk
of the September 30, 1996, backlog orders not filled by the end of 1996.
Further, the Company currently anticipates that by the end of the first
quarter of 1997 it will have filled all current backlog orders and will have
reduced its average fulfillment time to its goal of four weeks.

RESEARCH AND DEVELOPMENT
 
  As of December 1, 1996, 16 of the Company's 87 employees were engaged in
research and development and engineering. The Company designs many of the
aspects and components of its computing platforms, including lay-out, housings
and circuit boards, rather than incorporating other manufacturers' products.
The Company believes that its past efforts in this area have provided it with
significant technological advantages with regard to rugged computing
platforms, and the Company intends to continue to focus research and
development efforts on improving its core technologies. In addition, the
Company is beginning research and development efforts that are focused on
developing additional series of products that will address broader customer
preferences by providing toolboxes with a greater range of expandability, size
and price, all of which will provide the ruggedness, processing power and ease
of upgrade that characterize the Company's current products. Finally, the
Company's research and development efforts also involve developing customized
solutions for its customers who have unique, specialized requirements. The
Company has developed a number of customized solutions for customers in the
transportation, government and military, entertainment, field service and
engineering markets, and expects to continue to do so in appropriate cases.
 
  The Company spent approximately $0.3 million (on no net sales), $0.8 million
(representing 28% of net sales) and $0.9 million (representing 12% of net
sales) on research and development in the years ended December 31, 1993, 1994,
and 1995, respectively, and $1.0 million (representing 11% of net sales) in
the nine months ended September 30, 1996.
 
INTELLECTUAL PROPERTY
 
  In April 1996 the Company filed a provisional patent application related to
certain aspects of the design of its 5000 Series FIELD WORKSTATION notebook
computing platforms, including the technology module and features that enhance
its upgradeability and ruggedness. In July 1996, the Company filed a patent
application relating to the backplane design employed in its 7000 Series FIELD
WORKSTATION laptop computing platforms.
 
  The Company claims trademark rights in the following marks used in
connection with its products: FIELDWORKS, FIELDWORKS with design, FIELD
MOUSEPAD, FIELD WORKSTATION, and TECHNOLOGY MODULE. In June 1996 the Company
filed applications in the U.S. Patent and Trademark Office to register
FIELDWORKS with design, FIELD MOUSEPAD, FIELD WORKSTATION, and TECHNOLOGY
MODULE. Trademark applications are not normally examined for at least six
months from the date of filing, and the registrability of these trademarks has
not yet been determined. The Company is aware that there are third parties
that have claimed and may claim superior rights, in certain territories in the
United States, to the use of certain of the marks in which the Company claims
rights. See "Risk Factors--Dependence on Intellectual Property."
 
  The Company places copyright notices on all software that it develops for
inclusion in its products.
 
  In order to protect its trade secrets and other proprietary information, the
Company requires that all vendors and those customers that request
customization work execute non-disclosure agreements with respect to
confidentiality and ownership of the Company's proprietary information and of
any related innovations. The Company also requires all new employees to enter
into agreements covering confidentiality, non-disclosure, assignment of
inventions and non-solicitation of employees.
 
  The Company licenses the source code for Basic Input/Output System ("BIOS")
software that is included in the Company's products from two companies, Award
Software, Inc. and Phoenix Technologies, Ltd. The licenses are covered by
license agreements that, among other things, provide for the payment of
royalties by the Company and grant the Company the right to modify the
software as necessary. In addition, the Company purchases video controller
chips for inclusion in its products from Cirrus Logic, Incorporated and also
licenses the software
 
                                      33
<PAGE>
 
associated with these chips. The Company believes that the terms of these
licenses are standard for the industry.
 
  There can be no assurance that the measures the Company takes with respect
to intellectual property will be sufficient to protect its intellectual
property or that such intellectual property will provide the Company with any
competitive advantage. See "Risk Factors--Dependence on Intellectual
Property."
 
SERVICE AND SUPPORT
 
  The Company maintains a service and support program for the benefit of its
customers. The Company's staff is available to monitor order status, to
provide simple troubleshooting and to answer technical questions and questions
on post-installation issues and other product information. The Company
provides a one-year warranty program under which the Company agrees to
diagnose, repair and test any product, and the Company's goal is to return the
product to the customer within 48 hours. In addition to the standard warranty,
the Company also offers limited warranty programs for extended periods. The
Company provides product training, either at the Company's in-house training
facility or at the customer's site, including in some cases customized
programs. The Company also provides customers with updates on additions to the
Company's product line and on new options, accessories and software, and
performs upgrades for its customers. In the past, the most common upgrades
have been processors and display technology.
 
COMPETITION
 
  The Company believes that it currently occupies a niche in the market with
its rugged computing platforms. The Company currently faces direct competition
in this market niche from companies producing portable computers intended for
field use such as Amrel Technology, Inc., Badger Computers (a unit of Group
Financial Partners, Inc.), Dolch Computer Systems, Getac Corporation, Husky
Computers Inc., Itronix Corporation, Kontron Elektronik Corporation (a
subsidiary of Kontron Elektronik GmbH) and Panasonic Personal Computer
Company. To the extent the Company and its direct competitors expand and
develop this market niche, other manufacturers may turn their attention to
this niche and begin to produce products directly competitive with those
offered by the Company. The Company's 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. Many of the companies that produce or may
produce devices that compete, directly or indirectly, with the Company's
products have substantially greater financial, technological and marketing
resources than the Company. There can be no assurance that the Company will be
able to compete effectively against current or future competitors, or that
such competitors will not succeed in adapting more rapidly and effectively to
changes in technology or in the market or in developing or marketing products
that will be more widely accepted.
 
  Both the computer industry and the diagnostic and data collection instrument
industry are characterized by rapid technological change, changes in customer
requirements, frequent new product introductions and enhancements, and
evolving industry standards. The Company's success will depend in part on its
ability to keep pace with technological developments and emerging industry
standards and to respond to customer requirements by enhancing its current
products and introducing new products. Failure to anticipate or respond
rapidly to advances in technology and to adapt the Company's products
appropriately could have a material adverse effect on the success of the
Company's products and thus on the Company's business, financial condition and
results of operations. Technological advances may also increase the level of
competition in the rugged computing platform market.
 
 
                                      34
<PAGE>
 
  The Company's products compete with other rugged computer products primarily
on the basis of product reliability, functional expandability and system
design, which facilitates upgradeability and customization. See "Risk
Factors--Competition" and "--Risk of Technological Obsolescence."
 
MANUFACTURING
 
  The Company's manufacturing process consists primarily of the mechanical
subassembly, final assembly and testing of components and subassemblies
acquired from third party suppliers and subcontractors. These functions, along
with the final packaging of its products, are performed at the Company's
production facilities in Eden Prairie, Minnesota. The Company generally
assembles products upon receiving customer orders, and operates with little
finished goods inventory. The Company's goal is to fill customer orders within
four weeks; recently, however, the Company has experienced some backlog build-
up. See "Recent Events" and "--Backlog."
 
  The Company works with a number of subcontractors to assemble mechanical
components, to manufacture printed circuit boards, and to produce certain
components, all to the Company's design specifications. A number of these
components are made using tools that have been designed for, and belong to,
the Company, but that are located on the manufacturer's premises. The Company
has relationships with subcontractors who provide subassemblies on a turn-key
basis. The Company also purchases components directly from one or more third
party suppliers before forwarding them to subcontractors for assembly. In
general, the Company believes that these services are available from a number
of different companies.
 
  The Company employs extensive quality control systems and has a quality
assurance department that consists of seven full-time employees. The Company
received ISO 9001 quality assurance certification of its facilities in March
1996.
 
  The Company currently has a limited manufacturing capability, and has, to
date, had no experience with high volume production runs of its products.
There can be no assurance that the Company will successfully develop this
manufacturing capability. See "Risk Factors--Risks Associated with Managing
Growth." Further, the Company's products employ a number of advanced high
technology components and there can be no assurance that these components will
continue to be available on acceptable terms or at all. See "Risk Factors--
Dependence on Availability of Components."
 
EMPLOYEES
 
  As of December 1, 1996, the Company employed 87 full-time employees, of whom
33 were engaged primarily in manufacturing, 21 were engaged primarily in sales
and marketing, 16 were engaged primarily in engineering and research and
development, 13 were engaged primarily in administration and four were engaged
primarily in customer service. The Company also employs part-time or temporary
employees, mostly in manufacturing. None of the Company's employees are
represented by any labor union or other collective bargaining unit. The
Company believes that its relations with its employees are good.
 
  The Company maintains $1 million key man life insurance policies on the
lives of each of Gary J. Beeman, the Company's President and Chief Executive
Officer, and Robert C. Szymborski, the Company's Executive Vice President and
Chief Technical Officer, with the proceeds payable to the Company.
 
FACILITIES
 
  The Company currently leases an approximately 24,000 square foot facility in
Eden Prairie, Minnesota. This space houses the Company's headquarters and
manufacturing operations. This lease term expires in June 1999. The Company
believes that its existing facilities are
 
                                      35
<PAGE>
 
adequate to meet its requirements only through early to mid-1997 and currently
anticipates that it will begin searching for additional expansion space in
late 1996. The Company believes that suitable expansion space is available in
the proximity of its existing facilities. There can, however, be no assurance
that suitable facilities will be available when needed on acceptable terms, if
at all, or that the Company can relocate its manufacturing and other
operations without significant disruption. See "Risk Factors--Risks Associated
with Managing Growth."
 
  The Company also leases approximately 2,700 square feet in Springfield,
Virginia. The office of the Company's director of federal business, a repair
center, training center and demonstration center are located at the
Springfield facility. This lease term expires in June 2000.
 
LEGAL PROCEEDINGS
 
  On June 25, 1996, a shareholder of the Company commenced an action in
Minnesota state district court against the Company and certain directors of
the Company. The essence of the shareholder's allegations was that the Company
issued shares of Common Stock without the authorization of all shareholders in
violation of certain agreements and that certain of the Company's directors
treated the plaintiff unfairly. On October 8, 1996, the district court judge
granted the Company's motion for summary judgment dismissing the lawsuit, and
on October 29, 1996, judgment was entered in favor of the Company. The
shareholder has not filed an appeal, but has 90 days from October 29, 1996, to
do so.

COMMITTEES
 
  The Board of Directors has established a Compensation Committee and an Audit
Committee. The Compensation Committee makes recommendations concerning
executive salaries and incentive compensation for employees of the Company,
subject to ratification by the full Board of Directors, and administers the
Company's 1994 Long-Term Incentive and Stock Option Plan (the "1994 Stock
Option Plan").
 
  The Audit Committee reviews the results and scope of the audit and other
services provided by the Company's independent public accountants, as well as
the Company's accounting principles and its system of internal controls, and
reports the results of its review to the full Board of Directors and to
management.
 
LIMITATION OF LIABILITY; INDEMNIFICATION
 
  Both the Company's Amended and Restated Articles of Incorporation, as
currently in effect, and its Second Amended and Restated Articles of
Incorporation, which will be effective upon the closing of this offering,
provide that, to the fullest extent permitted by Minnesota law, a director
shall not be liable to the Company or its shareholders for monetary damages
for breach of fiduciary duty as a director.
 
  Both the Company's Amended and Restated Bylaws, as currently in effect, and
its Second Amended and Restated Bylaws, which will be effective upon the
closing of this offering, limit the liability of directors in their capacity
as directors to the full extent permitted by Minnesota law. As permitted by
Minnesota law, a director shall not be liable to the Company or its
shareholders for monetary damages for breach of fiduciary duty as a director,
except (i) for any
 
                                      38
<PAGE>
 
breach of the director's duty of loyalty to the Company or its shareholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) for dividends, stock
repurchases and other distributions made in violation of Minnesota law or for
violations of the Minnesota securities laws, (iv) for any transaction from
which the director derived an improper personal benefit or (v) for any act or
omission occurring prior to the effective date of the provision in the
Company's Amended and Restated Bylaws limiting such liability. These
provisions do not affect the availability of equitable remedies, such as an
action to enjoin or rescind a transaction involving a breach of fiduciary
duty, although, as a practical matter, equitable relief may not be available.
The above provisions also do not limit liability of the directors for
violations of, or relieve them from the necessity of complying with, the
federal securities law.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  Mr. George E. Kline has served as a member of the Compensation Committee of
the Board of Directors since the establishment of the Compensation Committee
in February 1995. Mr. David C. Malmberg has served as a member of the
Compensation Committee of the Board of Directors since October 1996.
 
  In December 1993, Venture Management, Inc., Profit Sharing Plan (of which
Mr. Kline is the sole trustee) purchased 1,500 shares of Common Stock for
$1,500.
 
  Mr. Kline personally guarateed the $500,000 bank line of credit that the
Company secured in July 1994 and amended in April 1995 to provide borrowing
capacity of up to $800,000. As consideration for Mr. Kline's guaranty, the
Company granted to Mr. Kline a warrant to purchase
 
                                      39
<PAGE>
 
100,000 shares of Common Stock at an exercise price of $1.00 per share. Mr.
Kline exercised this warrant in December 1995. In December 1995, the line of
credit was replaced by a revolving line of credit agreement, with a borrowing
capacity of $1,500,000. This line of credit is also personally guaranteed by
Mr. Kline; in consideration of the guarantee, the Company issued a three-year
warrant to Mr. Kline to purchase 40,000 shares of the Company's common stock
at $5.00 per share. (In March 1996, the term of the December 1995 line of
credit was extended through April 1997 and the borrowing capacity was
increased to $2,000,000; the additional $500,000 was guaranteed by a non-
affiliate shareholder of the Company who received a three-year warrant to
purchase 25,000 shares of the Company's common stock at $5.00 per share.)
 
  On May 30, 1996, Mr. Kline exercised a non-incentive stock option to
purchase 25,000 shares of the Company's common stock, which option had been
granted in March 1994, at an exercise price of $1.00 per share. Such shares
were issued in the name of Venture Management, Inc., a company of which Mr.
Kline is president. On June 21, 1996, Mr. Kline exercised a non-incentive
stock option to purchase 10,000 shares of the Company's common stock, which
option had been granted in August 1995, at an exercise price of $3.00 per
share.
 
  Mr. Kline is also a member of a limited liability company that is the
general partner of certain venture capital limited partnerships (such limited
liability company and limited partnerships, collectively, the "Brightstone
Entities," as more fully described in Note 7 to the table under "Principal
Shareholders"). As such, Mr. Kline may be deemed to share voting and
investment of power for the shares held by the Brightstone Entities; Mr.
Kline, however, disclaims beneficial ownership of all such shares except to
the extent of his proportionate pecuniary interest in the Brightstone
Entities. Mr. Kline also disclaims beneficial ownership of certain shares of
the Company's common stock owned of record by his wife. See "Principal
Shareholders" and "Certain Transactions."
 
STOCK PLANS
 
  1994 Stock Option Plan. The Board of Directors adopted the 1994 Stock Option
Plan on March 23, 1994, and the shareholders approved it on June 16, 1994.
Pursuant to the 1994 Stock Option Plan, executive officers, other employees
and consultants of the Company may receive options to purchase Common Stock.
The 1994 Stock Option Plan provides for the grant both of incentive stock
options intended to qualify for preferential tax treatment under Section 422
of the Internal Revenue Code of 1986, as amended, and nonqualified stock
options that do not qualify for such treatment. The exercise price of
incentive stock options must equal or exceed the fair market value of the
Common Stock at the time of grant. The 1994 Stock Option Plan also provides
for grants of stock appreciation rights, restricted stock awards and
performance awards and allows for the grant of restoration options.
 
  The Compensation Committee administers the 1994 Stock Option Plan and
approves awards thereunder. A total of 720,000 shares of Common Stock was
initially reserved for issuance under the 1994 Stock Option Plan. In May 1996,
the 1994 Stock Option Plan was amended to increase the number of shares of
Common Stock available for issuance to 1,100,000. In December 1996, the Board
of Directors amended the 1994 Stock Option Plan to increase the number of
shares of Common Stock available for issuance to 1,500,000, subject to
shareholder approval at a meeting to be held in January 1997. Incentive stock
options may only be granted under the Stock Option Plan to any full or part-
time employee of the Company (including officers and directors who are also
employees) and of its present and future subsidiary corporations. Full or
part-time employees, directors who are not employees, and consultants and
independent contractors to the Company or its subsidiaries or affiliates are
eligible to receive options which do not qualify as incentive stock options,
as well as other awards. In determining the persons to whom options and awards
shall be granted and the number of shares subject to each, the Board of
Directors may take into account the nature of services rendered by the
respective employees or consultants, their present and potential contributions
to the success of the Company, and such other factors as the Board of
Directors in its discretion shall deem relevant.
 
 
                                      40
<PAGE>
 
  The Board of Directors may amend or discontinue the 1994 Stock Option Plan
at any time, but may not make any revisions or amendments to the 1994 Stock
Option Plan without shareholder approval that increase the number of shares
subject to the 1994 Stock Option Plan, decrease the minimum exercise price,
extend the maximum exercise term, or modify the eligibility requirements. The
Board of Directors may not alter or impair any award granted under the 1994
Stock Option Plan without the consent of the holder of the award. The 1994
Stock Option Plan will expire March 23, 2004.
 
  Pursuant to the terms of the 1994 Stock Option Plan, appropriate adjustments
to the 1994 Stock Option Plan and outstanding options will be made in the
event of changes in the Common Stock through merger, consolidation,
reorganization, recapitalization, stock dividend, stock split, or other change
in corporate structure.
 
  Directors' Plans. On February 1, 1994, the Board of Directors adopted a
stock option plan for non-employee directors that provided for the automatic
grant of a non-qualified option covering 25,000 shares of Common Stock to each
non-employee director at the time of his or her initial election to the Board
of Directors, and an automatic grant of a non-qualified stock option to
purchase 10,000 shares of Common Stock each time such director was re-elected
for a subsequent term. All such options, which were granted outside of the
1994 Stock Option Plan, have an exercise price equal to the fair market value
of the Common Stock on the date of grant, became fully vested and exercisable
on the date of grant and had terms of 10 years from the date of grant.
 
  In December 1996, the Board of Directors approved the FieldWorks,
Incorporated 1996 Non-Employee Directors' Stock Option Plan (the "Directors'
Plan"), which will be submitted for the approval of the shareholders of the
Company in January 1997. Under the Directors' Plan, each non-employee director
will automatically receive non-qualified options to purchase shares of Common
Stock as follows: 25,000 shares (each an "Initial Grant") at the time of
election to the Board of Directors, and 10,000 shares (each an "Annual Grant")
at each re-election. All such options will have an exercise price equal to the
fair market value of a share of Common Stock on the day of grant and will
expire ten years after the date of grant. Initial Grants will vest one third
on the date of grant and one third on each of the first and second
anniversaries, and Annual Grants will vest six months from the date of grant.
 
  Savings Plan. The Company's savings plan (the "401(k) Plan") was adopted by
the Company effective January 1996.

    and/or investment power with respect to securities. Shares of Common Stock
    subject to options or warrants currently exercisable or exercisable within
    60 days of December 20, 1996, are deemed outstanding for computing the
    percentage of the person holding such options or warrants but are not
    deemed outstanding for computing the percentage of any other person. This
    table does not reflect any shares of Common Stock that these existing
    shareholders may acquire in this offering. Except as indicated by
    footnote, the Company believes that the persons named in this table, based

                             CERTAIN TRANSACTIONS
 
  For certain information regarding George Kline, a director of the Company,
see "Management--Compensation Committee Interlocks and Insider Participation."
 
  On September 13, 1994, Brightstone IV and Brightstone V, partnerships of
which George Kline, a director of the Company, is a general partner, loaned
the Company an aggregate of $300,000 (the "1994 Loans"). The 1994 Loans bore
interest at an annual rate of 10% and were due on February 28, 1995. In
connection with the 1994 Loans, the Company issued warrants to purchase an
aggregate of 30,000 shares of Common Stock at a price of $3.00 per share to
Brightstone IV and Brightstone V. In March 1995, the Company repaid $200,000
original principal amount of the 1994 Loans, together with $13,750 interest.
In June 1995, the Company repaid the remaining $100,000 original principal
amount of the 1994 Loans, together with $2,500 interest.
 
  In May and June 1996, Brightstone VI and Brightstone VII loaned the Company
an aggregate of $1,540,000 (the "June Loans"). The June Loans bore interest at
an annual rate of 10% and were due on August 2, 1996. In connection with the
June Loans, the Company issued to Brightstone Capital warrants (the "June
Warrants") to purchase 15,000 shares of Common Stock at a price of $10.00 per
share.
 
  On July 15, 1996, Brightbridge loaned the Company $500,000. This loan, which
is represented by a promissory note (the "July Note"), bears interest at 10%
per year and was initially due on December 31, 1996; provided, that the July
Note would become payable in full within thirty (30) days after the effective
date of any registration statement relating to an initial public offering of
the Company's equity securities. In connection with this loan, the Company
issued to Brightbridge warrants (the "July Warrants") to purchase a number of
shares determined in accordance with a formula contained in the July Warrants
at an exercise price equal to 80% of the price to public of shares of the
Company's common stock in the Company's first registration statement to be
declared effective.
 
  On July 29, 1996 the Company sold 300,000 shares of Series A Convertible
Preferred Stock to Network General Corporation for $10.00 per share and in
connection therewith issued warrants to purchase 24,000 shares of Common Stock
at $10.00 per share. The number of shares to be issued upon conversion, the
number of shares subject to the warrants and the exercise price of the
warrants are all subject to adjustment in the event that the Price to Public
in this Offering is less than $12.50 per share. In that event, the conversion
price will be reduced to a price equal to 80% of the Price to Public and the
warrant exercise price and the number of warrant shares will be similarly
adjusted.
 
  As of August 2, 1996, the Company and Brightbridge amended the July Note to
subordinate it to certain bank indebtedness of the Company and to extend its
due date from December 31, 1996, to May 1, 1997.
 
  On August 2, 1996, the Company repaid all principal amounts outstanding on
the June Loans, together with an aggregate of $27,168 in interest.

  In September 1996, Brightstone VI and Brightstone VII loaned the Company an
aggregate of $750,000. These loans, which are represented by Promissory Notes
(the "September Notes"), bear interest at 12% per year and were initially due
on the date 180 days from the date of each such loan; provided, that the
September Notes would become payable in full within thirty (30) days after the
effective date of any registration statement relating to an initial public
offering of the Company's equity securities. In connection with the September
Notes, the Company issued to Brightstone VI, Brightstone VII and Brightstone
Capital warrants (the "September Warrants") to purchase a number of shares
determined in accordance with a formula contained in the September Warrants,
which formula (other than the formula in the warrants issued to Brightstone
Capital) depended on whether the September Notes were repaid before or after
the date 90 days after the date of each such note, at an exercise price equal
to 80% of the price per share received by the Company in its next sale of
equity securities with gross proceeds of $2.5 million or more.
 
  As of October 15, 1996, the Company agreed with Brightstone Capital,
Brightstone VI, Brightstone VII and Brightbridge to amend the June Warrant,
the July Warrants, the September Notes and the September Warrants. Pursuant to
these amendments, the final due date of each of such Notes was extended to May
1, 1997; provided, that all such Notes are payable in full within 30 days
after the effective date of any registration statement relating to an initial
public offering of the Company's equity securities; the exercise price under
each of such Warrants was amended to $5.00 per share; and the September
Warrants were amended to provide that they are exercisable for an aggregate of
45,000 shares of Common Stock. As a result of the exercise price amendment,
the July Warrants are currently exercisable for 20,000 shares of Common Stock.

PROVISIONS OF THE COMPANY'S ARTICLES AND BYLAWS AND THE MINNESOTA BUSINESS
CORPORATION ACT
 
  The existence of authorized but unissued preferred stock, described above,
and certain provisions of the Company's Second Amended and Restated Articles
of Incorporation and Second Amended and Restated Bylaws (both of which will be
effective upon the closing of this offering) and of Minnesota law, described
below, could have an anti-takeover effect. These provisions are intended to
provide management flexibility, to enhance the likelihood of continuity and
stability in the composition of the Board of Directors and in the policies
formulated by the Board of Directors and to discourage an unsolicited takeover
of the Company if the Board of Directors determines that such a takeover is
not in the best interests of the Company and its shareholders. However, these
provisions could have the effect of discouraging certain attempts to acquire
the Company's which could deprive the Company's shareholders of opportunities
to sell their shares of Common Stock at prices higher than prevailing market
prices.
 
  Section 302A.671 of the Minnesota Business Corporation Act (the "MBCA")
applies, with certain exceptions, to any acquisition of voting stock of the
Company (from a person other than the Company, and other than in connection
with certain mergers and exchanges to which the Company is a party) resulting
in the beneficial ownership of 20% or more of the voting stock then
outstanding. Section 302A.671 requires approval of any such acquisitions by a
majority vote of the shareholders of the Company prior to its consummation. In
general, shares acquired in the absence of such approval are denied voting
rights and are redeemable at their then fair market value by the Company
within 30 days after the acquiring person has failed to give a timely
information statement to the Company or the date the shareholders voted not to
grant voting rights to the acquiring person's shares.
 
  Section 302A.673 of the MBCA generally prohibits any business combination by
the Company, or any subsidiary of the Company, with any shareholder which
purchases 10% or more of the Company's voting shares (an "interested
shareholder") within four years following such 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 the Board of Directors, before the interested
shareholder's share acquisition date.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar with respect to the Common Stock will be

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has not been any public market for Common
Stock of the Company. Future sales of substantial amounts of Common Stock in
the public market could adversely affect the prevailing market price and
impair the Company's ability to raise additional funds.
 
  Upon completion of this offering, the Company will have outstanding
8,047,403 shares of Common Stock (or 8,309,903 shares if the Underwriters'
over-allotment option is exercised in full). Of those shares, 1,750,000 shares
(or 2,012,500 shares, if the Underwriters' over-allotment option is exercised
in full) will be freely tradeable without restriction or further registration
under the Securities Act, unless held by "affiliates" of the Company, as that
term is defined in Rule 144 under the Securities Act (whose sales would be
subject to certain volume limitations and other restrictions described below).
 
  The remaining 6,297,403 shares of Common Stock will be "restricted
securities," as that term is defined in Rule 144 under the Securities Act, and
may be sold in the public market only if registered or if they qualify for an
exemption from registration under Rule 144, Rule 144(k), Rule 701 or
otherwise. The Representative has requested, and the Company has agreed, to
solicit all shareholders to agree that they will not sell, directly or
indirectly, any Common Stock without the prior consent of the Representative
for a period of   days from the date of this Prospectus. Of the shares not
subject to this agreement, (i) approximately      shares will be eligible for
immediate sale without restriction pursuant to Rule 144(k) on the effective
date of this offering, (ii) approximately      shares will be eligible for
sale, subject to compliance with the volume limitations and other restrictions
of Rule 144, 90 days after the effective date of this offering, and (iii)
approximately      shares will become eligible for sale under Rule 144 after
the expiration of the two-year holding periods from the dates of acquisition,
which end between    and   . Beginning on the 181st day after the date of this
Prospectus, when the agreements not to sell shares expire, (iv) approximately
2,519,000 of the shares may become eligible for sale without restriction
pursuant to Rule 144(k), (v) approximately 2,982,637 of the shares (including
approximately 2,190,902 shares owned by affiliates of the Company) will become
eligible for sale, subject to compliance with the volume limitations and other
restrictions of Rule 144, and (vi) approximately 795,766 shares will become
eligible for sale under Rule 144 after the expiration of the two-year holding
periods from the dates of acquisition, which end between September 11, 1997
and July 15, 1998.
 
  In general, under Rule 144, as currently in effect, if at least two years
have elapsed from the date that shares of Common Stock were acquired from the
Company or an affiliate of the Company, then the holder is entitled to sell in
"brokers' transactions" or to market makers, within any three-month period
commencing 90 days after the date of this Prospectus, a number of shares that
does not exceed the greater of (i) one percent of the then outstanding shares
of Common Stock (80,474 shares immediately after this offering) or (ii)
generally, the average weekly trading volume in the Common Stock during the
four calendar weeks preceding the filing of a Form 144 with respect to such
sale, subject to certain other limitations and restrictions. In addition, a
person who is not deemed to have been an affiliate of the Company at any time
during the three months preceding a sale, and who has beneficially owned the
shares proposed to be sold for at least three years, would be entitled to sell
such shares under Rule 144(k) without regard to the requirements described
above.
 
  Any employee, officer or director of or consultant to the Company who
purchased his or her shares pursuant to a written compensatory plan or
contract is entitled to rely on the resale provisions of Rule 701, which
permits non-affiliates to sell their Rule 701 share without complying with the
public information, holding period, volume limitation or notice provisions of
Rule 144 and which permits Affiliates to sell their Rule 701 shares without
complying with the Rule 144 holding period restrictions, in each case
commencing 90 days after the date of this Prospectus. The Company has issued
644,500 shares under plans or contracts that satisfy the requirements of Rule
701.
 
                                      47

  The Company intends to file registration statements on Form S-8 under the
Securities Act to register the sale of the 1,500,000 and 300,000 shares
reserved for issuance under, respectively, the 1994 Stock Option Plan and the
Directors' Plan. The filing of such registration statements will permit the
resale of such shares by non-affiliates in the public market without
restriction under the Securities Act. Such registration statements are
expected to be filed soon after the date of this Prospectus and will
automatically become effective upon filing. "See "Management--Stock Option
Plans" and "Description of Capital Stock--Warrants and Options."
 
  In addition, after this offering, the holders of approximately 546,223
shares of Common Stock (including the maximum of 138,889 shares of Common
Stock issuable upon conversion of $5,000,000 of the principal amount of
certain loans) and warrants to purchase approximately 338,078 shares of Common
Stock (together, the "Registrable Securities") will be entitled to certain
rights to cause the Company to register the sale of such shares under the
Securities Act. After this offering, if the Company proposes to register any
of its securities under the Securities Act for its own account, holders of
Registrable Securities are entitled to notice of such registration and are
entitled to include Registrable Securities therein, provided, among other
conditions, that the underwriters of any such offering have the right to limit
the number of shares included in such registration. The holders of certain of
the Registrable Securities may require the Company to prepare and file one or
more registration statements on Form S-3 at its expense, and the Company is
required to use its best efforts to effect such registration, subject to
certain conditions and limitations. Registration of such shares would result
in such shares becoming freely tradeable without restriction under the
Securities Act (except for shares purchased by affiliates of the Company)
immediately upon the effectiveness of such registration.
 
  The Company can make no prediction as to the effect, if any, that sales of
shares of Common Stock or the availability of Common Stock for sale will have
on the market price prevailing from time to time. Nevertheless, sales of
substantial amounts of the Common Stock in the public markets or the
perception that such sales will occur could adversely affect the market price
or the future ability to raise capital through an offering of its equity
securities. See "Risk Factors--Shares Eligible for Future Sale; Registration
Rights."

  The Underwriting Agreement provides that the obligations of the several
Underwriters thereunder are subject to approval of certain legal matters by
counsel and to various other considerations. The nature of obligations is such
that they are committed to purchase and pay for all of the above shares of
Common Stock if any are purchased.
 
  The Underwriters, through the Representative, have advised the Company that
they propose to offer the Common Stock initially at the Price to Public set
forth on the cover page of this Prospectus; that the Underwriters may allow to
selected dealers a concession of $     per share; and that such dealers may
reallow a concession of $     per share to certain other dealers. After the
public offering, the offering price and other selling terms may be changed by
the Underwriters. Application has been made for the Common Stock to be
included for quotation on the Nasdaq National Market. The Representative has
advised the Company that it does not intend to confirm sales to any account
over which it exercises discretionary authority.
 
  The Company has granted to the Underwriters a 30-day over-allotment option
to purchase up to an aggregate of 262,500 additional shares of Common Stock,
exercisable at the Price to Public less the underwriting discount. If the
Underwriters exercise such over-allotment option, then each of the
Underwriters will have a firm commitment, subject to certain conditions, to
purchase approximately the same percentage thereof as the number of shares of
Common Stock to be purchased by it as shown in the above table, bears to the
1,750,000 shares of Common Stock offered hereby. The Underwriters may exercise
such option only to cover over-allotments made in connection with the sale of
the shares of Common Stock offered hereby. In addition, the Company has agreed
to pay the Representative at the closing of this offering a non-accountable
expense allowance of 2% of the aggregate public offering price (including the
aggregate public offering price of any over-allotment shares) to cover
expenses incurred by the Underwriters in connection with this offering,
reduced by amounts advanced by the Company, which totaled $10,000 on the date
of this Prospectus.
 
  In connection with this offering, the Company has agreed to issue and sell
to the Representative, for nominal consideration, warrants to purchase a
number of shares of Common Stock equal to 10% of the shares of Common Stock
sold in this offering, exclusive of any shares of Common Stock sold pursuant
to the Underwriters' over-allotment option (the "Representative's Warrants").
The Representative's Warrants will be initially exercisable at a price per
share equal to 120% of the Price to Public, commencing one year from the date
of this Prospectus, and will continue to be exercisable for a period of four
years after such date. The Representative's Warrants are restricted from sale,
transfer, assignment or hypothecation for a period of 12 months from the
effective date of this offering, except to officers, partners or successors of
the Representative. The exercise price of the Representative's Warrants and
the
 
                                      49
<PAGE>
 
number of shares of Common Stock issuable upon exercise thereof are subject to
adjustment under certain circumstances. The Representative's Warrants grant to
the holder or holders thereof certain rights regarding the registration of the
Common Stock issuable upon exercise of the Representative's Warrants.
 
  At the request of the Representative, the Company solicited all of its
shareholders to agree that they will not publicly sell or dispose of any
shares of Common Stock for a period of 180 days after the date on which the
Registration Statement is declared effective by the Commission, without the
prior written consent of the Representative. Shareholders who beneficially own
   shares of Common Stock after the offering have agreed to such restrictions.
See "Shares Eligible for Future Sale."
 
  The Company has agreed to indemnify the Underwriters against certain
liabilities, losses and expenses, including liabilities under the Securities
Act, or to contribute to payments the Underwriters may be required to make in
respect thereof.
 
  Prior to this offering, there has been no public market for the Common
Stock. Consequently, the initial public offering price has been determined
through negotiations between the Company and the Representative. Among the
factors considered in determining the initial public offering price were
prevailing market and economic conditions, estimates of the business potential
and prospects of the Company, the present state of the Company's business
operations, an assessment of the Company's management and the consideration of
the above factors in relation to the market valuation of companies in related
businesses. See "Risk Factors--No Prior Market for Common Stock; Determination
of Offering Price."

  The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Dorsey & Whitney LLP, Minneapolis, Minnesota. Certain
legal matters in connection with this offering will be passed upon for the
Underwriters by Fredrikson & Byron, P.A. Members of Dorsey & Whitney LLP

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To FieldWorks, Incorporated:
 
  We have audited the accompanying consolidated balance sheets of FieldWorks,
Incorporated (a Minnesota corporation) and Subsidiaries as of December 31,
1994 and 1995, and the related consolidated statements of operations,
shareholders' equity and cash flows for each of the three years in the period
ended December 31, 1995. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of FieldWorks, Incorporated
and Subsidiaries as of December 31, 1994 and 1995, and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1995 in conformity with generally accepted accounting
principles.

1. NATURE OF BUSINESS:
 
 Operating Activities
 
  FieldWorks, Incorporated (FieldWorks or the Company), a Minnesota
corporation, was organized on October 2, 1992, and was in the development
stage until significant revenue-generating activities commenced in 1994.
FieldWorks is engaged in the design, development and marketing of portable
field-based computer workstations, and has integrated certain field
instrumentation platforms with state-of-the-art computer technology to produce
a new class of portable instrumentation equipment capable of simultaneously
supporting many types of diagnostic communication and computing capabilities
required by the field service, medical and engineering professions. FieldWorks
markets its products worldwide through a direct sales force, independent sales
representatives and distributors, original equipment manufacturers, value
added resellers and system integrators.
 
  The Company's future operations are dependent upon the attainment of certain
objectives, including the continued successful development, marketing and sale
of its products, and the continued design and implementation of new
technology. After products have been successfully introduced into a market,
additional time may be necessary before continuing profitability is achieved.
During this time, the Company may require additional financing which may not
be available at favorable terms and conditions.
 
 Merger With Paragon Technology, Incorporated and Subsequent Distribution
 
  In August 1995, FieldWorks completed a merger agreement with Paragon
Technology, Incorporated (Paragon), a Pennsylvania company engaged in software
research and development. The merger was effected through a share-for-share
exchange of 25,300 shares of FieldWorks' common stock for all of the
outstanding shares of Paragon common stock. The merger was accounted for as a
pooling of interests and, accordingly, the accompanying consolidated financial
statements reflect the combined activities of FieldWorks and Paragon
(collectively, the Company) for the entire 1995 fiscal year. Amounts in the
1993 and 1994 financial statements have not been restated to reflect Paragon
amounts, as the effects are not material to the Company's results of
operations or financial position.
 
  On November 11, 1996, the Company's board of directors approved the
distribution of all of the issued and outstanding common stock of Paragon, as
a dividend to Company shareholders of record as of November 15, 1996. The
distribution is being effected in order to take advantage of anticipated
capital-raising and product development opportunities on a separate-company
basis. The Company expects that the distribution will take place before
December 31, 1996.
 
  Paragon's results of operations for the year ended December 31, 1995 and for
the nine-month periods ended September 30, 1995 and 1996, as well as the
estimated loss on disposition of Paragon have been presented as a discontinued
operation in the accompanying statements of operations. Revenues applicable to
Paragon were approximately $274,000, $208,000 and $156,000 for the year ended
December 31, 1995 and the nine-month periods ended September 30, 1995 and
1996.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Principles of Consolidation
 
  The consolidated financial statements of the Company include the accounts of
the Company and its wholly owned subsidiaries. All intercompany accounts and
transactions have been eliminated in consolidation.

               (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
 
 Interim Financial Statements
 
  The consolidated balance sheet as of September 30, 1996 and the related
consolidated statements of operations and cash flows for the nine-month
periods ended September 30, 1995 and 1996, and the consolidated statement of
shareholders' equity for the nine-month period ended September 30, 1996 are
unaudited. However, in the opinion of management, these interim financial
statements include all adjustments (consisting of only normal recurring
adjustments) which are necessary for the fair presentation of the results for
the interim periods presented. The results of operations for the unaudited
nine-month period ended September 30, 1996 are not necessarily indicative of
the results which may be expected of the entire 1996 fiscal year.
 
 Pro Forma Net Loss Per Common Share
 
  Unaudited pro forma net loss per common share was computed by dividing net
loss by the weighted average number of shares of common stock outstanding
during each period, including the effect of the conversion of preferred stock
to common stock (see Note 5). The impact of common stock equivalents has been
excluded from the computation of weighted average common shares outstanding,
except as follows, as the effect would be antidilutive. Pursuant to Securities
and Exchange Commission rules, stock options and warrants granted within one
year of the date of the contemplated initial public offering have been
included in the calculation of common stock equivalents, using the treasury
stock method, as if they were outstanding for all periods presented.
 
 Cash
 
  Cash consists of amounts held in the Company's checking accounts. Its
carrying value approximates fair value due to the short maturity of the
instruments.
 
 Inventories
 
  Inventories are stated at the lower of cost or market value, as determined
by the first-in, first-out cost method, and consisted of the following:

 Property and Equipment
 
  Property and equipment are recorded at cost. Repair and maintenance costs
which do not significantly extend the lives of the respective assets are
charged to expense as incurred. Depreciation is computed using the straight-
line method over the related assets' useful lives, ranging from three to five
years.
 
 Warranties
 
  The Company provides a one-year warranty from the date of sale. Estimated
warranty costs are accrued in the same period in which the related revenue is
recognized, based on anticipated parts and labor costs utilizing historical
experience. Ultimate results may differ from such estimates.

 Revenue Recognition
 
   The Company recognizes product revenue, net of estimated returns, at the
time the products are shipped. Revenue for services performed is recognized as
earned.
 
 Export Sales and Significant Customers
 
  Export sales were approximately $1,070,000 and $2,859,000 for the years
ended December 31, 1994 and 1995. For the year ended December 31, 1994, sales
to one customer represented 14% of net sales. For the year ended December 31,
1995, there were no customers representing over 10% of net sales.
 
 Research and Development Costs
 
  Research and development costs are charged to expense as incurred.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities as of the date of the
financial statements. Estimates also affect the reported amounts of revenues
and expenses during the periods presented. Ultimate results could differ from
those estimates.
 
 Recently Issued Accounting Standards
 
  Statement of Financial Accounting Standards (SFAS) No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of," establishes standards for the recognition and measurement of impairment
of long-lived assets and certain identifiable intangibles. The adoption of
this pronouncement in fiscal 1996 did not have a material impact on the
Company's results of operations or financial position.
 
  SFAS No. 123, "Accounting for Stock-Based Compensation," encourages, but
does not require, a fair value based method of accounting for employee stock
options or similar equity instruments. It also allows an entity to elect to
continue to measure compensation cost under Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" (APB No. 25), but
requires pro forma disclosures of net income (loss) and net income (loss) per
share as if the fair value based method of accounting had been applied. The
Company has elected to continue to measure compensation cost under APB No. 25
and comply with the pro forma disclosure requirements of SFAS No. 123.
 
3. INCOME TAXES:
 
  The Company accounts for income taxes under the liability method, which
requires recognition of deferred income tax assets and liabilities for the
expected future income tax consequences under enacted tax laws of temporary
differences between the financial reporting and tax bases of assets and
liabilities.

  As of December 31, 1995, the Company had approximately $2,200,000 of net
operating loss carryforwards for federal income tax purposes that are
available to offset future taxable income through the year 2010. Additional
tax losses of approximately $1,000,000 were generated for the nine months
ended September 30, 1996. Certain restrictions caused by the change in
ownership resulting from sales of stock will limit annual utilization of the
net operating loss carryforwards.
 
  The components of the Company's deferred tax asset for the years ended
December 31 are as follows:

4. LINES OF CREDIT AND NOTES PAYABLE:
 
 Lines of Credit
 
  In July 1994, the Company entered into a $500,000 line-of-credit agreement
with a bank, which was amended in April 1995 to provide increased borrowing
capacity of up to $800,000.
 
  In December 1995, this line of credit matured and was replaced by a new
revolving line-of- credit agreement (the New Line), with borrowing capacity of
$1,500,000, limited to a borrowing base, as defined in the agreement.
Availability as of December 31, 1995 was $340,000. This credit facility bears
interest at prime plus 1.5%, payable monthly, and is collateralized by
substantially all assets of the Company. Additionally, the New Line is
personally guaranteed by a shareholder of the Company.
 
  In March 1996, the New Line was extended through April 1997 and its
borrowing limit increased to $2,000,000. The incremental borrowing capacity of
$500,000 was personally guaranteed by a shareholder of the Company.
 
  The following information relates to the Company's lines of credit for the
periods ended December 31:

  The Company's existing line-of-credit agreements contain certain covenants
which, among other matters, require the Company to maintain minimum levels of
tangible net worth and certain other financial ratios. The covenants also
limit additional indebtedness, capital expenditures and payment of dividends.
The Company was in compliance with all debt covenants as of December 31, 1995.
 
  In December 1996, the Company repaid all amounts owed under its lines of
credit, with proceeds received from the bridge financing discussed in Note 10.
 
 Notes Payable
 
  At December 31, 1994, the Company had two 10%, $150,000 unsecured notes
payable to related parties. These notes were repaid in March and June 1995.
 
  In May through September 1996, the Company entered into certain short-term
(bridge) financing agreements with related and other parties, for a total of
$2,890,000. These borrowings are due the earlier of 30 days following the
consummation of an initial public offering of common stock or May 1, 1997,
bear interest at rates ranging from 10% to 12%, and are unsecured. At
September 30, 1996, outstanding borrowings under these agreements were
$1,350,000.
 
5. SHAREHOLDERS' EQUITY:
 
  The Company was originally capitalized by the founders who contributed
personal property and computer equipment in exchange for 2,350,000 shares of
$.001 par value common stock.
 
  In December 1993, the Company completed a private placement of 2,500,000
shares of common stock at $1 per share, receiving $1,833,650 in proceeds prior
to December 31, 1993. The remaining proceeds of $666,350 were received through
March 20, 1994 and are reflected as notes receivable from sale of common stock
in the accompanying 1994 consolidated financial statements.
 
  In December 1994, the Company completed a private placement (1994 Placement)
of 479,100 shares of common stock at $3 per share, receiving proceeds of
$804,198 prior to December 31, 1994. The remaining proceeds of $633,102 were
received through February 23, 1995 and are reflected as notes receivable from
sale of common stock in the accompanying 1994 financial statements. In 1995,
the Company extended the 1994 Placement to allow for issuance of an additional
354,334 shares of common stock at $3 per share.
 
  In July 1996, the Company sold 300,000 shares of Series A, $.001 par value
preferred stock (Preferred Stock) at $10 per share. The Preferred Stock
contains a liquidation preference of $10 per share and is redeemable at the
option of the holder for $10 per share, exercisable beginning in the year
2001. The Preferred Stock is convertible at the option of the holder on a
share-for-share basis into common stock. Conversion to shares of common stock
is automatic upon the consummation of an initial public offering. The
accompanying consolidated balance sheets reflect actual shareholders' equity
at September 30, 1996 and pro forma to reflect the conversion of all preferred
shares to common stock.
 
  The holder of the preferred stock was also granted warrants to purchase
24,000 shares of the Company's common stock at an exercise price of $10 per
share. The warrants are exercisable through July 2001.

6. WARRANTS:
 
  In December 1993, the Company entered into an agreement with the owner of
its leased office space, offering the lessor the opportunity to earn warrants
to purchase up to 115,000 shares of the Company's common stock at an exercise
price of $1 per share, the estimated cash rent value, expiring in February
1999. The economic value of these warrants was allocated over the term of the
lease. In August 1994, the lease was terminated, and rights to unearned
warrants as of the lease termination date were forfeited.
 
  Warrants for the purchase of 100,000 and 40,000 shares at exercise prices of
$1 and $5 per share were issued to a shareholder in 1994 and 1995,
respectively, in connection with personal guarantees of the Company's line-of-
credit agreements (see Note 4). In December 1995, the 1994 $1 per share
warrants were exercised for the purchase of 100,000 shares. As the proceeds
from this stock exercise were received in January 1996, this amount has been
classified as notes receivable from sale of common stock in the accompanying
1995 consolidated balance sheet.
 
  In January 1995, five-year warrants for the purchase of 44,400 shares at an
exercise price of $3.35 per share were granted to an accredited investor in
connection with the 1994 Placement (see Note 5).
 
  In May 1995, the Company issued warrants for a total of 30,000 shares to two
shareholders. The warrants are exercisable at $3 per share any time on or
prior to May 10, 2000 and were granted in connection with loans made to the
Company in 1994.
 
  In March 1996, three-year warrants for the purchase of 25,000 shares at an
exercise price of $5 per share were granted to a shareholder in exchange for a
personal guarantee of the Company's amended line-of-credit agreement (see Note
4).
 
  In June through September 1996, the Company granted warrants for the
purchase of 84,000 shares of common stock in connection with the bridge
financing agreements discussed in Note 4. These warrants are exercisable at $5
per share, at any time subsequent to the consummation of an initial public
offering, expiring at dates ranging from June through September 1999.
 
7. STOCK OPTION AND 401(K) PLANS:
 
 Stock Option Plan
 
  In June 1994, the Company adopted a long-term incentive and stock option
plan (the Plan) for employees, directors and consultants of the Company. Under
the Plan, options are granted at an exercise price equal to the fair market
value of the common stock, as determined by the Company's board of directors,
at the date of grant. Incentive stock options are granted to employees, and
vest over varying periods not to exceed three years. The Plan also provides
for nonqualified options to be granted to directors and consultants, including

10. BRIDGE FINANCING AND PROPOSED INITIAL PUBLIC OFFERING:
 
  During December 1996, the Company raised approximately $4,684,000 through a
private debt offering, after payment of $316,000 in related underwriting
discounts and offering costs. Such bridge notes bear interest at 10% and
mature at the earlier of June 30, 1997, which date may be extended to December
31, 1997 at the option of the Company, or thirty days following the effective
date of a registration statement filed in connection with an initial public
offering (IPO). In connection with this private debt offering, 250,000 five-
year warrants to purchase shares of the Company's common stock were issued at
an exercise price equal to 80% of the IPO price, or $6.40 in the event the IPO
does not occur prior to June 30, 1998.

               (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
 
  In November 1996, the Company signed a letter of intent to obtain financing
through an IPO of approximately 1,750,000 shares of common stock in early
1997. The proceeds of the offering will be used to repay the bridge financing
arrangements, to fund capital expenditures and for working capital purposes.
In connection with the offering, the underwriter will receive a warrant to
purchase 175,000 shares of common stock at 120% of the IPO price. Upon
completion of the IPO, the Company will be authorized to issue 20 million
shares of Common Stock, $.001 par value, and five million shares of
undesignated preferred stock, $.001 par value.
 
  Supplementary net loss per common share, giving effect to the assumed
retirement of debt with proceeds from the IPO and elimination of related
interest expense, was $.09 and $.20 for the year ended December 31, 1995 and
the nine months ended September 30, 1996.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 302A.521 of the Minnesota Statutes provides that a corporation shall
indemnify any person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of such person against
judgments, penalties, fines (including, without limitation, excise taxes
assessed against such person with respect to any employee benefit plan),
settlements and reasonable expenses, including attorneys' fees and
disbursements, incurred by such person in connection with the proceeding, if,
with respect to the acts or omissions of such person complained of in the
proceeding, such person (1) has not been indemnified therefor by another
organization or employee benefit plan for the same judgments, penalties or
fines; (2) acted in good faith; (3) received no improper personal benefit and
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 as they will be in effect upon
closing of this offering (Exhibit 3.4 hereto, which is incorporated herein by
reference).
 
  Under Section of the Underwriting Agreement (Exhibit 1.1 hereto, which is
incorporated herein by reference), the Underwriter has agreed to indemnify,
under certain conditions, the Company, its directors, certain of its officers
and persons who control the Company within the meaning of the Securities Act
of 1933, as amended, against certain liabilities.

ITEM 17. UNDERTAKINGS
 
  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.
 
  The undersigned registrant further undertakes that:
 
    (1) It will provide to the Underwriters at the closing specified in the
  Underwriting Agreement certificates in such denominations and registered in
  such names as required by the Underwriters to permit prompt delivery to
  each purchaser.
 
    (2) 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.
 
    (3) 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 this offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

to vote, except that a special meeting for the purpose of considering any action
to directly or indirectly facilitate or affect a business combination, including
any action to change or otherwise affect the composition of the board of
directors for that purpose, must be called by 25% or more of the voting power of
all shares entitled to vote. A shareholder or shareholders holding the requisite
percentage of the voting power of all shares entitled to vote may demand a
special meeting of the shareholders by written notice of demand given to the
chief executive officer or chief financial officer of the corporation and
containing the purposes of the meeting. Within 30 days after receipt of demand
by one of those officers, the board of directors shall cause a special meeting

business at any regular or special meeting. In case a quorum shall not be
present at a meeting, the meeting may be adjourned from time to time without
notice other than announcement at the time of adjournment of the date, time and
place of the adjourned meeting. If a quorum is present, a meeting may be
adjourned from time to time without notice other than announcement at the time
of adjournment of the date, time and place of the adjourned meeting. At
adjourned meetings at which a quorum is present, any business may be transacted

otherwise, shall have one vote for each share having voting power registered in

meeting shall be by ballot. All questions shall be decided by a majority vote of
the number of shares entitled to vote and represented at the meeting at the time
of the vote except if otherwise required by statute, the articles of
incorporation, or these bylaws.

exceeding 60 days preceding the date of any meeting of shareholders, as a record
date for the determination of the shareholders entitled to notice of, and to
vote at, such meeting, notwithstanding any transfer of shares on the books of
the corporation after any record date so fixed. If the board of directors fails
to fix a record date for determination of the shareholders entitled to notice
of, and to vote at, any meeting of shareholders, the record date shall be the
20th day preceding the date of such meeting.
 
     Section 2.07. Notice of Meetings. There shall be mailed to each
shareholder, shown by the books of the corporation to be a holder of record of
voting shares, at his address as shown by the books of the corporation, a notice
setting out the time and place of each regular meeting and each special meeting,

prior thereto (unless otherwise provided in section 2.04 hereof); except that
notice of a meeting at which a plan of merger or exchange is to be considered
shall be mailed to all shareholders of record, whether entitled to vote or not,
at least fourteen days prior thereto. Every notice of any special meeting called
pursuant to section 2.03 hereof shall state the purpose or purposes for which
the meeting has been called, and the business transacted at all special meetings
shall be confined to the purposes stated in the notice. The written notice of
any meeting at which a plan of merger or exchange is to be considered shall so
state such as a purpose of the meeting. A copy or short description of the plan
of merger or exchange shall be included in or enclosed with such notice.
 
     Section 2.08. Waiver of Notice. Notice of any regular or special meeting
                   ------------------                                        
may be waived by any shareholder either before, at or after such meeting orally
or in writing signed by such shareholder or a representative entitled to vote
the shares of such shareholder. A shareholder, by his attendance at any meeting
of shareholders, shall be deemed to have waived notice of such meeting, except
where the shareholder objects at the beginning of the meeting to the transaction
of business because the meeting is not lawfully called or convened, or objects
before a vote on an item of business because the item may not lawfully be
considered at that meeting and does not participate in the consideration of the
item at that meeting.
 
     Section 2.09. Written Action. Any action which might be taken at a meeting
                   --------------

construed to preclude any director from serving this corporation in any other
capacity and receiving proper compensation therefor.

                            SHARES OF COMMON STOCK

                               FIELDWORKS, INC.

subscribe for and purchase from Fieldworks, Inc., a Minnesota corporation (the
"Company"), up to ____________________ (______) fully paid and nonassessable
shares of the Company's common stock, or such greater of lesser number of such
shares as may be determined by application of the anti-dilution provisions of
this warrant, at the price of ____________ ($_____) per share, subject to
adjustments as noted below (the warrant exercise price").

          This warrant may be exercised by Investor at any time or from time to
time on or prior to ________, 19xx.

          This warrant is subject to the following provisions, terms and
conditions:

          1.   (a) The rights represented by this warrant may be exercised by
the holder hereof, in whole or in part, by written notice of exercise delivered
to the Company at least twenty (20) days prior to the intended date of exercise
and by the surrender of this warrant (properly endorsed if required) at the
principal office of the Company and upon payment to it by cash, certified check
or bank draft of the purchase price for such shares. 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 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
the 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 has not been exercised shall also be delivered to the holder hereof
within such time. No fractional shares shall be issued upon the exercise of this
warrant.

               (b) In lieu of payment, the rights represented by this warrant
may also be exercised by a written notice of exercise specifying that the
Investor wishes to convert all of this warrant (the "Conversion Right") into
that number of shares of the Company's common stock as follows: the number of
shares of the Company's common stock equal to the quotient obtained by dividing
(x) the value of the shares subject to the warrant (determined by subtracting
the aggregate warrant exercise price in effect immediately prior to the exercise
of the Conversion Right from the aggregate fair market value of the shares of
common stock issuable upon exercise of this warrant immediately
<PAGE>
 
prior to the exercise of the Conversion Right) by (y) the fair market value of
one share of Company common stock immediately prior to the exercise of the
Conversion Right.  For  purposes of this section 1(b), the fair market value of
a share of Company common stock as of a particular date (the "Determination
Date") shall mean:
 
                    (i) If the Company's common stock is traded on an exchange
          or is quoted on the National Association of Securities Dealers, Inc.
          Automated Quotation ("NASDAQ") National Market System, then the
          closing or last sale price, respectively, reported for the business
          day immediately preceding the Determination Date.
                          
                   (ii) If the Company's common stock is not traded on an
          exchange or on the NASDAQ National Market System but is quoted on
          NASDAQ, then the mean of the closing bid and asked prices reported for
          the business day immediately preceding the Determination Date.
          
                  (iii) If the Company's common stock is not publicly traded,
          then as determined in good faith by the Company's Board of Directors
          upon a review of relevant factors.
            
          2.   The Company covenants and agrees that 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.
The Company further covenants and agrees that during the period within which the
rights represented by this warrant may be exercised, the Company will 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.

          3.   The warrant exercise price shall be subject to adjustment form
time to time as hereinafter provided in this section 3.

               (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 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

                                      -2-
<PAGE>
 
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 shares, then, as a condition of such reorganization, reclassification,
consolidation, merger or sale, the holder of this warrant shall have the right
to purchase and receive upon the basis and upon the terms and conditions
specified in this warrant and in lieu of the shares of the common stock of the
Company immediately theretofore purchasable and receivable upon the exercise of
the rights represented hereby, such shares of stock, other securities or assets
as would have been issued or delivered to the holder of this warrant if it had
exercised this warrant and had received such shares of common stock prior to
such 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 the registered
holder of this warrant at the last address of such holder appearing on the books
of the Company, the obligation to deliver to such holder such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to purchase.

               (c) Upon each adjustment of the warrant exercise price, the
holder of this warrant shall thereafter be entitled to purchase, at the warrant
exercise price resulting from such adjustment, the number of shares obtained by
multiplying the warrant exercise price in effect immediately prior to such
adjustment by the number of shares purchasable pursuant hereto immediately prior
to such adjustment and dividing the product thereof by the warrant exercise
price resulting from such adjustment.
 
               (d) Upon any adjustment of the warrant exercise price, the
Company shall give written notice thereof, by first class mail, postage prepaid,
addressed to the registered holder of this warrant at the address of such holder
as shown on the books of the Company, which notice shall state the warrant
exercise price resulting from such adjustment and the increase or decrease, if
any, in the number of shares purchasable at such price upon the exercise of this
warrant, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based.
 
               4.  This warrant shall not entitle the holder hereof to any
voting rights or other rights as a shareholder of the Company.
 
               5.  The holder of this warrant, by acceptance hereof, agrees to
give written notice to the Company before transferring this warrant or
transferring any shares of the Company's common stock issuable or issued upon
the exercise of this warrant of the holder's intention to do so, describing
briefly the manner of any proposed transfer of this warrant or such holder's
intention as to the shares of common stock issuable upon the exercise hereof or
the intended disposition to be made of shares of common stock upon such
exercise. Promptly upon receiving such written notice, the Company shall present

                                      -3-
<PAGE>
 
copies thereof to counsel for the Company. If, in the opinion of such counsel,
the proposed transfer of this warrant or disposition of shares may be effected
without registration or qualification (under any federal or state law) of this
warrant or the shares of common stock issuable or issued upon the exercise
hereof, the Company, as promptly as practicable, shall notify such holder of
such opinion, whereupon such holder shall be entitled to transfer this warrant,
or to exercise this warrant in accordance with its terms and dispose of the
shares received upon such exercise or to dispose of shares of common stock
received upon the previous exercise of this warrant, all in accordance with the
terms of the notice delivered by such holder to the Company, provided that an
appropriate legend in substantially the form set forth at the end of this
warrant respecting the foregoing restrictions on transfer and disposition may be
endorsed on this warrant or the certificates for such shares.
 
               6.  Subject to the provisions of section 5, 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 he/it 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.
 
               7.  Neither this warrant nor any term hereof may be changed,
waived, discharged or terminated orally but only by an instrument in writing
signed by the party against which enforcement of the change, waiver, discharge
or termination is sought.
 
               8.  The Company further grants to Investor the registration
rights, as provided in Exhibit A, with respect to the common stock purchased
pursuant to the exercise of the rights contained herein.

                                   EXHIBIT A

                        REGISTRATION RIGHTS PROVISIONS

1. Registration of Stock.
   --------------------- 
 
     1.1  Definitions.
          ------------
 
          "Commission" shall mean the Securities and Exchange Commission or any
           ----------
other federal agency at the time administering the Securities Act.

          "Company" shall mean FieldWorks, Inc., a Minnesota corporation.
           -------                                                       
 
          "Common Shares" shall mean the shares of Common Stock authorized by
           -------------
the Company's Restated Articles of Incorporation and any additional shares of
Common Stock which may be authorized in the future by the Company, and any stock
into which such Common Shares may hereafter be changed.

          "Registrable Securities" shall mean (i) the Common Stock issued upon
           ----------------------                                             
conversion of the Warrant, issued to _______________, dated __________, 19xx,
and (ii) any additional securities issued with respect to the above described
securities upon any stock split, stock dividend, recapitalization or similar
event, provided, however, that none of the above described securities shall be
treated as Registrable Securities if (a) they have been sold to or through a
broker or dealer or underwriter in a public distribution or a public securities
transaction, or (b) they have been sold in a transaction exempt from the
registration and prospectus delivery requirements of the Securities Act so that
all transfer restrictions and restrictive legends with respect thereto are
removed upon the consummation of such sale amended.

          "Securities Act" shall mean the Securities Act of 1933, as
           --------------                                           
amended.
 
     1.2 Piggyback Registration.  Each time the Company shall determine to
         -----------------------                                        
proceed with the actual preparation and filing of a registration statement under
the Securities Act in connection with the proposed offer and sale for money of
any of its securities by it or any of its security holders (other than a
registration statement on Form S-8 or other limited purpose form), the Company
will give written notice of its determination to all record holders of
Registrable Securities. Upon the written request of a record holder of any
shares of Registrable Securities given within 30 days after receipt of any such
notice from the Company, the Company will, except as herein provided, cause all
Common Shares of the Registrable Securities, the record holders of which have so
requested

                                      A-1
<PAGE>
 
registration thereof, to be included in such registration statement, all to the
extent requisite to permit the sale or other disposition by the prospective
seller or sellers of the Common Shares to be so registered; provided, however,
that nothing herein shall prevent the Company from, at any time, abandoning or
delaying any registration; provided further, however, that if the Company
determines not to proceed with a registration after the registration statement
has been filed with the Commission and the Company's decision not to proceed is
primarily based upon the anticipated public offering price of the securities to
be sold by the Company, the Company shall promptly complete the registration for
the benefit of those selling security holders who wish to proceed with a public
offering of their Common Shares of the Registrable Securities and who bear all
expenses in excess of $25,000 incurred by the Company as the result of such
registration after the Company has decided not to proceed. If any registration
pursuant to this Section shall be underwritten in whole or in part, the Company
may require that the Common Shares requested for inclusion pursuant to this
Section be included in the underwriting on the same terms and conditions as the
securities otherwise being sold through the underwriters. If in the good faith
judgment of the managing underwriter of such public offering the inclusion of
all of the Common Shares originally covered by requests for registration would
reduce the number of shares to be offered by the Company or interfere with the
successful marketing of the shares of stock offered by the Company, the number
of Common Shares to be included in the underwritten public offering may be
reduced in the following manner: the Common Shares held by directly by officers
and directors of the Company (other than Registrable Securities) shall be
excluded from such underwritten public offering to the extent required by the
managing underwriter, and if a further reduction in the number of shares is
required, such shares shall be selected pro rata among the holders thereof
requesting inclusion in such registration. Those Common Shares which are thus
excluded from the underwritten public offering shall be withheld from the market
by the holders thereof for a period, not to exceed 90 days, which the managing
underwriter reasonably determines is necessary in order to effect the
underwritten public offering.

     1.3 Registration Procedures.  If and whenever the Company required by the
         -----------------------                                              
provisions of Section 1.2 to effect the registration of shares of Registrable
Securities under the Securities Act, the Company will:

          (a)  prepare and file with the Commission a registration statement
with respect to such securities, and use its best efforts to cause such
registration statement to become and remain effective for such period as may be
reasonably necessary to effect the sale of such securities, not to exceed nine
months;
 
          (b)  prepare and file with the Commission such amendments to such
registration statement and supplements to the prospectus contained therein

                                      A-2
<PAGE>
 
as may be necessary to keep such registration statement effective for such
period as may be reasonably necessary to effect the sale of such securities, not
to exceed nine months;

          (c)  furnish to the security holders participating in such
registration and to the underwriters of the securities being registered such
reasonable number of copies of the registration statement, preliminary

reasonably request in order to facilitate the public offering of such
securities;
 
          (d)  use its best efforts to register or qualify the securities
covered by such registration statement under such state securities or blue sky
laws of such jurisdictions as such participating holders may reasonably request
within 20 days following the original filing of such registration statement,
except that the Company shall not for any purpose be required to execute a
general consent to service of process or to qualify to do business as a foreign
corporation in any jurisdiction wherein it is not so qualified;
 
          (e)  notify the security holders participating in such registration,
promptly after it shall receive notice thereof, of the time when such
registration statement has become effective or a supplement to any prospectus
forming a part of such registration statement has been filed;
 
          (f)  notify such holders promptly of any request by the Commission for
the amending or supplementing of such registration statement or prospectus or
for additional information;
 
          (g)  prepare and file with the Commission, promptly upon the request
of any such holders, any amendments or supplements to such registration
statement or prospectus which, in the opinion of counsel for such holders (and
concurred in by counsel for the Company), is required under the Securities Act
or the rules and regulations thereunder in connection with the distribution of
the Conversion Shares by such holder;
 
          (h)  prepare and promptly file with the Commission and promptly notify
such holders of the filing of such amendment or supplement to such registration
statement or prospectus as may be necessary to correct any statements or
omissions if, at the time when a prospectus relating to such securities is
required to be delivered under the Securities Act, any event shall have occurred
as the result of which any such prospectus or any other prospectus as then in
effect would include an untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in the light of the
circumstances in which they were made, not misleading;

                                      A-3

obtain knowledge thereof, of the issuance of any stop order by the Commission
suspending the effectiveness of such registration statement or the initiation or
threatening of any proceeding for that purpose and promptly use its best efforts
to prevent the issuance of any stop order or to obtain its withdrawal if such
stop order should be issued;
 
          (j)  not file any amendment or supplement to such registration
statement or prospectus to which a majority in interest of such holders shall
have reasonably objected on the grounds that such amendment or supplement does
not comply in all material respects with the requirements of the Securities Act
or the rules and regulations thereunder, after having been furnished with a copy
thereof at least five business days prior to the filing thereof, unless in the
opinion of counsel for the Company the filing of such amendment or supplement is
reasonably necessary to protect the Company from any liabilities under any
applicable federal or state law and such filing will not violate applicable law;
and
 
          (k)  at the request of any such holder, furnish on the effective date
of the registration statement and, if such registration includes an underwritten
public offering, at the closing provided for in the underwriting agreement: (i)

dated such respective dates, from the independent certified public accountants
of the Company, addressed to the underwriters, if any, and to the holder or
holders making such request, covering such matters as such underwriters and
holder or holders may reasonably request, in which letters such accountants
shall state (without limiting the generality of the foregoing) that they are
independent certified public accountants within the meaning of the Securities
Act and that in the opinion of such accountants the financial statements and
other financial data of the Company included in the registration statement or
any amendment or supplement thereto comply in all material respects with the
applicable accounting requirements of the Securities Act.

excess of $15,000, underwriting discounts and commissions and transfer taxes for

     1.5  Indemnification.
          ---------------

          (a) The Company will indemnify and hold harmless each holder of shares
of Registrable Securities that are included in a registration statement pursuant
to the provisions of this Agreement and any underwriter (as defined in the
Securities Act) for such holder and each person, if any, who controls such
holder or such underwriter within the meaning of the Securities Act, from and
against any and all loss, damage, liability, cost and expense to which such
holder or any such underwriter or controlling person may become subject under
the Securities Act or otherwise, insofar as such losses, damages, liabilities,
costs or expenses are caused by any untrue statement or alleged untrue statement
of any material fact contained in such registration statement, any prospectus
contained therein or any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading; provided,
however, that the Company will not be liable in any such case to the extent that
any such loss, damage, liability, cost or expense arises out of or is based upon
an untrue statement or alleged untrue statement or omission or alleged omission
so made in conformity with written information furnished by such holder, such
underwriter or such controlling person specifically for use in the preparation
thereof.

          (b) Each holder of shares of Registrable Securities which are included
in a registration pursuant to the provisions of this Section 1 will indemnify
and hold harmless the Company, any controlling person and any underwriter from
and against any and all loss, damage, liability, cost or expense to which the
Company or any controlling person and/or any underwriter may become subject
under the Securities Act or otherwise, insofar as such losses, damages,
liabilities, costs or expenses are caused by any untrue or alleged untrue
statement of any material fact contained in such registration statement, any
prospectus contained therein or any amendment or supplement thereto, or arise
out of or are based upon the omission or the alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was so made in
reliance upon and in strict conformity with written information furnished by
such holder specifically for use in the preparation thereof.

          (c) Promptly after receipt by an indemnified party pursuant to the
provisions of paragraph (a) or (b) of this section of notice of the commencement

                                      A-5
<PAGE>
 
of any action involving the subject matter of the foregoing indemnity
provisions, such indemnified party will, if a claim thereof is to be made
against the indemnifying party pursuant to the provisions of said paragraph (a)
or (b), promptly notify the indemnifying party of the commencement thereof; but
the omission to so notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than hereunder.
In case such action is brought against any indemnified party and it notifies the
indemnifying party of the commencement thereof, the indemnifying party shall
have the right to participate in, and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party; provided, however,
if the defendants in any action include both the indemnified party and the
indemnifying party and there is a conflict of interest which would prevent
counsel for the indemnifying party from also representing the indemnified party,
the indemnified party or parties shall have the right to select separate counsel
to participate in the defense of such action on behalf of such indemnified party
or parties. After notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party will
not be liable to such indemnified party pursuant to the provisions of said
paragraph (a) or (b) for any legal or other expense subsequently incurred by
such indemnified party in connection with the defense thereof other than
reasonable costs of investigation, unless (i) the indemnified party shall have
employed counsel in accordance with the proviso of the preceding sentence, (ii)
the indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after the notice of the commencement of the action, or (iii) the indemnifying
party has authorized the employment of counsel for the indemnified party at the
expense of the indemnifying party.

          1.6  Stand-Off Agreement. Each holder of Registrable Securities
               -------------------
agrees, so long as such holder holds at least 1% of the Company's outstanding
voting equity securities, in connection with the Company's initial public
offering of the Company's Common Shares that, upon request of the Company or the
underwriters managing the underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Shares of the Company other than those included
in the registration without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not exceeding 120
days) from the effective date of such registration as may be requested by the
underwriters; provided, that all other holders of at least 1% of the Company's
outstanding voting equity securities and all of the officers and directors of
the Company who own stock of the Company also agree to such restrictions.

                                    WARRANT
                                      FOR
                            SHARES OF COMMON STOCK
                                      OF
                           FIELDWORKS, INCORPORATED


          FOR VALUE RECEIVED, Brightstone Capital, Ltd. or its successors or
assigns ("Holder"), is hereby entitled to subscribe for and purchase from
Fieldworks, Incorporated, a Minnesota corporation (the "Company"), Fifteen
Thousand (15,000) fully paid and nonassessable shares of the Company's Common
Stock (the "Warrant Shares") at the exercise price of Ten Dollars ($10.00) per
share (the "Warrant Exercise Price"), subject to adjustment as provided in
Section 3 of this warrant.

          This warrant may be exercised by Investor at any time after the
initial public offering of the Company's Common Stock is effective until a date
on or prior to three years from the date hereof.

          This warrant is subject to the following provisions, terms and
conditions:

          1.   (a)  The rights represented by this warrant may be exercised by
the holder hereof, in whole or in part, by written notice of exercise delivered
to the Company at least twenty (20) days prior to the intended date of exercise
and by the surrender of this warrant (properly endorsed if required) at the
principal office of the Company and upon payment to it by cash, certified check
or bank draft of the purchase price for such shares or by exercise of the
Conversion Right as provided in (b) below.  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 Company of the Warrant Exercise
Price unless the Conversion Right has been exercised.  Certificates for the
shares of stock so purchased, bearing the restrictive legend set forth at the
end of this warrant, shall be delivered to the 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 has not been exercised shall
also be delivered to the holder hereof within such time.  No fractional shares
shall be issued upon the exercise of this warrant.

               (b)  In lieu of payment, the rights represented by this warrant
may also be exercised by a written notice of exercise specifying that the
Investor wishes to convert all of this warrant (the "Conversion Right") into
that number of shares of Common Stock as follows: the number of shares of Common
Stock equal to the quotient obtained by dividing (x) the value of the shares
subject to the warrant (determined by subtracting the aggregate warrant exercise
price in effect immediately prior to the exercise of the Conversion Right from
the aggregate fair market value of
<PAGE>
 
the shares of Common Stock issuable upon exercise of this warrant immediately
prior to the exercise of the Conversion Right) by (y) the fair market value of
one share of Common Stock immediately prior to the exercise of the Conversion
Right. For purposes of this section 1(b), the fair market value of a share of
Common Stock as of a particular date (the "Determination Date") shall mean:

               (i)    If the Company's Common Stock is traded on an exchange or
     is quoted on the National Association of Securities Dealers, Inc. Automated
     Quotation ("NASDAQ") National Market System, then the closing or last sale
     price, respectively, reported for the business day immediately preceding
     the Determination Date.

               (ii)   If the Company's Common Stock is not traded on an exchange
     or on the NASDAQ National Market System but is quoted on NASDAQ, then the
     mean of the closing bid and asked prices reported for the business day
     immediately preceding the Determination Date.

          2.   The Company covenants and agrees that 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.
The Company further covenants and agrees that during the period within which the
rights represented by this warrant may be exercised, the Company will 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.

          3.   This warrant shall be exercisable for the number of Warrant
Shares and at the Warrant Exercise Price first given above, subject to
adjustment from time to time as provided below:

               (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 share.

               (b)  If any 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 shares, then,
     as a condition of 

                                      -2-
<PAGE>
 
     such reorganization, reclassification, consolidation, merger or sale, the
     holder of this warrant shall have the right to purchase and receive upon
     the basis and upon the terms and conditions specified in this warrant and
     in lieu of the shares of the Common Stock of the Company immediately
     theretofore purchasable and receivable upon the exercise of the rights
     represented hereby, such shares of stock, other securities or assets as
     would have been issued or delivered to the holder of this warrant if it had
     exercised this warrant and had received such shares of Common Stock prior
     to such 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 the registered holder of this warrant at the last address of such
     holder appearing on the books of the Company, the obligation to deliver to
     such holder such shares of stock, securities or assets as, in accordance
     with the foregoing provisions, such holder may be entitled to purchase.

               (c)  If the Company takes any other action, or if any other event
     occurs, which does not come within the scope of the provisions of Section
     3(a) or (b), but which should result in an adjustment in the Warrant
     Exercise Price and/or the number of shares subject to this warrant in order
     to fairly protect the purchase rights of the holder of this warrant, an
     appropriate adjustment in such purchase rights shall be made by the
     Company.

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

               (e)  Upon any adjustment of the Warrant Exercise Price, the
     Company shall give written notice thereof, by first class mail, postage
     prepaid, addressed to the registered holder of this warrant at the address
     of such holder as shown on the books of the Company, which notice shall
     state 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.   The holder of this warrant, by acceptance hereof, agrees to give
written notice to the Company before transferring this warrant or transferring
any shares of the Company's Common Stock issuable or issued upon the exercise of
this warrant of the holder's intention to do so, describing briefly the manner
of any proposed transfer of this warrant or such holder's intention as to the
shares of Common Stock issuable upon the exercise hereof or the intended
disposition to be made of shares of Common Stock upon such exercise.  Promptly
upon receiving such written notice, the Company shall present copies thereof to
counsel for the Company.  If, in the opinion of such counsel, the proposed
transfer of this warrant or disposition of shares may be effected without
registration or qualification (under any federal or state law) of this warrant
or the shares of Common Stock issuable or issued upon the exercise hereof, the
Company, as promptly as practicable, shall notify such holder of such opinion,
whereupon such holder shall be entitled to transfer this warrant, or to exercise
this warrant in accordance with its terms and dispose of the shares received
upon such exercise or to dispose of shares of Common Stock received upon the
previous exercise of this warrant, all in accordance with the terms of the
notice delivered by such holder to the Company, provided that an appropriate
legend in substantially the form set forth at the end of this warrant respecting
the foregoing restrictions on transfer and disposition may be endorsed on this
warrant or the certificates for such shares.

          6.   Subject to the provisions of Section 5, 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 he/it 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.

          7.   Neither this warrant nor any term hereof may be changed, waived,
discharged or terminated orally but only by an instrument in writing signed by
the party against which enforcement of the change, waiver, discharge or
termination is sought.

          8.   The Company agrees that each time it shall determine to proceed
with the preparation and filing of a registration statement under the Securities
Act it will use all reasonable efforts to allow the inclusion of the Warrant
Shares in such registration statement; provided, however, that the inclusion of
the Warrant Shares

                                      -4-
<PAGE>
 
in such registration statement shall be subject to the approval of the managing
underwriter and subject to the good faith determination of the managing
underwriter that the inclusion of such Warrant Shares would not reduce the
number of shares to be offered by the Company nor interfere with the successful
marketing of such shares by the Company.

          IN WITNESS WHEREOF, the Company has caused this warrant to be signed
and delivered by a duly authorized officer as of the 19th day of June, 1996.

                                   NO. ____



     THIS BRIDGE LOAN AGREEMENT (this "Agreement") is dated as of July 15, 1996,
by and between Fieldworks, Incorporated, a Minnesota corporation (the
"Company"), and _____________________ (the "Investor").

                                   RECITALS:

          (a)  Whereas, the Company needs cash to fund its operations until such
     time as it can complete a debt or equity financing; and

          (b)  Whereas, the Investor desires to lend funds to the Company on the
     terms and conditions set forth in this Agreement; and

          (c)  Whereas, other investors ("Other Investors") may lend funds to
     the Company on terms and conditions equivalent to those set forth in this
     Agreement.

     Accordingly, in consideration of the foregoing, the mutual promises set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

     1.   Loan/Promissory Note.  The Investor agrees to lend to the Company
          --------------------                                             
$__________ and the Company agrees to deliver to the Investor a promissory note,
in the form attached hereto as Exhibit A (the "Note"), in a like amount.  The
                               ---------                                     
delivery of the Note shall be made concurrently with delivery of funds to the
Company in the amount set forth above.

     2.   Warrants.  In consideration of the loan, the Company shall issue to
          --------                                                           
the Investor, concurrently with delivery of the Note, a warrant, in the form
attached hereto as Exhibit B (the "Warrant"), to purchase that number of shares
                   ---------                                                   
of Common Stock of the Company as provided in the Warrant.  The shares of Common
Stock issuable upon exercise of the Warrants are referred to hereinafter as the

     3.   Repayment.  All outstanding principal and accrued interest on the Note
          ---------

                                               -----------------      
notwithstanding the foregoing, the Note shall be payable in full within thirty
(30) days after the effective date (the "Effective Date") of any Registration
Statement. Except in the event a Registration Statement is filed and declared
effective, the Note may not be prepaid.

     4.   Restrictions on Transfer.  The Note, Warrant and Warrant Stock shall
          ------------------------                                            
be subject to certain restrictions on transfer identified in the Note and
Warrant.

     5.   Representations and Warranties of the Company.  The Company represents
          ---------------------------------------------                         
and warrants to the Investor that this Agreement has been duly authorized by all
necessary corporate action on behalf of the Company, has been duly executed and
delivered by an authorized officer of the Company, and is a valid and binding
agreement on the part of the Company.  All corporate action necessary to the
authorization, issuance, and delivery of the Note, the Warrant, and the Warrant
Stock (collectively, a "Unit") has been taken on or prior to the date hereof.

     6.   Representations and Warranties of the Investor.  The Investor
          ----------------------------------------------               
represents and warrants to the Company as follows:

          (a)  That the Investor is in a financial position to hold the Units
     for an indefinite period of time and is able to bear the economic risk and
     withstand a complete loss of the Investor's investment in the Units;

          (b)  That the Investor believes the Investor, either alone or with the
     assistance of the Investor's own professional advisor, has such knowledge
     and experience in financial and business matters that the Investor is
     capable of reading and interpreting financial statements and evaluating the
     merits and risks of the prospective investment in the Units and has the net
     worth to undertake such risks;

          (c)  That the Investor has obtained, to the extent the Investor deems
     necessary, the Investor's own personal professional advice with respect to
     the risks inherent in the investment in the Units and the suitability of an
     investment in the Units in light of the Investor's financial condition and
     investment needs;

          (d)  That the Investor believes that the investment in the Units is
     suitable for the Investor based upon the Investor's investment objectives
     and financial needs, and the Investor has adequate means for providing for
     the Investor's current financial needs and personal contingencies and has
     no need for liquidity of investment with respect to the Units;

          (e)  That the Investor has been given access to full and complete
     information regarding the Company and has utilized such access to the
     Investor's satisfaction for the purpose of obtaining information and,
     particularly, the Investor has either attended or been given reasonable
     opportunity to attend a meeting with representatives of the Company for the
     purpose of asking questions of, and receiving answers from, such
     representatives concerning the Company and to obtain any additional

                                      -2-
<PAGE>
 
     information, to the extent reasonably available, necessary to verify the
     accuracy of information provided to the Investor;

          (f)  That the Investor recognizes that an investment in the Units
     involves a high degree of risk, including, but not limited to, the risk of
     economic losses from operations of the Company;

          (g)  That the Investor recognizes that in addition to the proceeds
     from the sale of Units, the Company will require additional financing to
     fund current and proposed operations, and there can be no assurances that
     additional financing can be obtained;

          (h)  That the Investor realizes that (i) the purchase of the Units is
     a long-term investment; (ii) the purchaser of the Units must bear the
     economic risk of investment for an indefinite period of time because the
     Notes, Warrants and Warrant Stock have not been registered under the
     Securities Act or under the securities laws of any state and, therefore,
     none of such securities can be sold unless they are subsequently registered
     under said laws or exemptions from such registrations are available; (iii)
     the Investor may not be able to liquidate the Investor's investment in the
     event of an emergency or pledge any of such securities as collateral for
     loans; and (iv) the transferability of such securities is restricted and
     (A) requires the written consent of the Company, and (B) legends will be
     placed on the Notes and Warrants referring to the applicable restrictions
     on transferability.

          (i)  That the Investor certifies, under penalties of perjury, that the
     Investor is NOT subject to the backup withholding provisions of Section
     3406(a)(i)(C) of the Internal Revenue Code of 1986, as amended (Note: You
     are subject to backup withholding if (i) you fail to furnish your Social
     Security number or taxpayer identification number herein; (ii) the Internal
     Revenue Service notifies the Company that you furnished an incorrect Social
     Security number or taxpayer identification number; (iii) you are notified
     that you are subject to backup withholding; or (iv) you fail to certify
     that you are not subject to backup withholding or you fail to certify your
     Social Security number or taxpayer identification number);

          (j)  That the Investor is a bona fide resident of, is domiciled in,
     and received the offer and made the decision to invest in the Units in, the
     state set forth on the signature page below under "Addresses" and that the
     Units are being purchased by the Investor in the Investor's name solely for
     the Investor's own beneficial interest and not as nominee for, or on behalf
     of, or for the beneficial interest of, or with the intention to transfer
     to, any other person, trust or organization.

                                    WARRANT
                                      FOR
                            SHARES OF COMMON STOCK
                                      OF
                           FIELDWORKS, INCORPORATED


          FOR VALUE RECEIVED, ____________ or its successors or assigns
("Holder"), is hereby entitled to subscribe for and purchase from Fieldworks,
Incorporated, a Minnesota corporation (the "Company"), up to the total number of
Warrant Shares (as calculated pursuant to Section 3(A)) of fully paid and
nonassessable shares of the Company's Common Stock, 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 exercise price of Ten Dollars ($10.00) per
share (the "Warrant Exercise Price").

          This warrant may be exercised by Investor at any time after the
initial public offering of the Company's Common Stock is effective until a date
on or prior to three years from the date hereof.

          This warrant is subject to the following provisions, terms and
conditions:

          1.   (a) The rights represented by this warrant may be exercised by
the holder hereof, in whole or in part, by written notice of exercise delivered
to the Company at least twenty (20) days prior to the intended date of exercise
and by the surrender of this warrant (properly endorsed if required) at the
principal office of the Company and upon payment to it by cash, certified check
or bank draft of the purchase price for such shares or by exercise of the
Conversion Right as provided in (b) below.  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 Company of the Warrant Exercise
Price unless the Conversion Right has been exercised.  Certificates for the
shares of stock so purchased, bearing the restrictive legend set forth at the
end of this warrant, shall be delivered to the 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 has not been exercised shall
also be delivered to the holder hereof within such time.  No fractional shares
shall be issued upon the exercise of this warrant.

               (b) In lieu of payment, the rights represented by this warrant
may also be exercised by a written notice of exercise specifying that the
Investor wishes to convert all of this warrant (the "Conversion Right") into
that number of shares of Common Stock as follows: the number of shares of Common
Stock equal to the quotient obtained by dividing (x) the value of the shares
subject to the warrant 
<PAGE>
 
(determined by subtracting the aggregate warrant exercise
price in effect immediately prior to the exercise of the Conversion Right from
the aggregate fair market value of the shares of Common Stock issuable upon
exercise of this warrant immediately prior to the exercise of the Conversion
Right) by (y) the fair market value of one share of Common Stock immediately
prior to the exercise of the Conversion Right. For purposes of this section
1(b), the fair market value of a share of Common Stock as of a particular date
(the "Determination Date") shall mean:

               (i)   If the Company's Common Stock is traded on an exchange or
     is quoted on the National Association of Securities Dealers, Inc. Automated
     Quotation ("NASDAQ") National Market System, then the closing or last sale
     price, respectively, reported for the business day immediately preceding
     the Determination Date.

               (ii)  If the Company's Common Stock is not traded on an exchange
     or on the NASDAQ National Market System but is quoted on NASDAQ, then the
     mean of the closing bid and asked prices reported for the business day
     immediately preceding the Determination Date.

          2.   The Company covenants and agrees that 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.
The Company further covenants and agrees that during the period within which the
rights represented by this warrant may be exercised, the Company will 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.

          3.   This warrant shall be exercisable for the number of Warrant
Shares, as adjusted, as provided for in this Section 3(A), and subject to
adjustment from time to time as provided in this Section 3(B).

     (A)  Warrant Shares:  The number of shares which may be purchased by the
          ---------------                                                    
holder of this warrant, subject to adjustment under this Section 3(C), shall be
calculated as follows:

         20% x [Principal Amount of Promissory Note]         = Warrant Shares
     ---------------------------------------------------
              Warrant Exercise Price per share

     (B)  Anti-dilution:
          --------------

               (i)   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 

                                      -2-
<PAGE>
 
     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 share.

               (ii)  If any 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 shares, then,
     as a condition of such reorganization, reclassification, consolidation,
     merger or sale, the holder of this warrant shall have the right to purchase
     and receive upon the basis and upon the terms and conditions specified in
     this warrant and in lieu of the shares of the Common Stock of the Company
     immediately theretofore purchasable and receivable upon the exercise of the
     rights represented hereby, such shares of stock, other securities or assets
     as would have been issued or delivered to the holder of this warrant if it
     had exercised this warrant and had received such shares of Common Stock
     prior to such 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 the registered holder of this warrant at the last
     address of such holder appearing on the books of the Company, the
     obligation to deliver to such holder such shares of stock, securities or
     assets as, in accordance with the foregoing provisions, such holder may be
     entitled to purchase.

               (iii) If the Company takes any other action, or if any other
     event occurs, which does not come within the scope of the provisions of
     Section 3(B)(i) or (ii), but which should result in an adjustment in the
     Warrant Exercise Price and/or the number of shares subject to this warrant
     in order to fairly protect the purchase rights of the holder of this
     warrant, an appropriate adjustment in such purchase rights shall be made by
     the Company.

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

                                      -3-
<PAGE>
 
               (v)   Upon any adjustment of the Warrant Exercise Price, the
     Company shall give written notice thereof, by first class mail, postage
     prepaid, addressed to the registered holder of this warrant at the address
     of such holder as shown on the books of the Company, which notice shall
     state the Warrant Exercise Price resulting from such adjustment and the
     increase or decrease, if any, in the number of shares purchasable at such
     price upon the exercise of this warrant, setting forth in reasonable detail
     the method of calculation and the facts upon which such calculation is
     based.

          4.   This warrant shall not entitle the holder hereof to any voting
rights or other rights as a shareholder of the Company.

          5.   The holder of this warrant, by acceptance hereof, agrees to give
written notice to the Company before transferring this warrant or transferring
any shares of the Company's Common Stock issuable or issued upon the exercise of
this warrant of the holder's intention to do so, describing briefly the manner
of any proposed transfer of this warrant or such holder's intention as to the
shares of Common Stock issuable upon the exercise hereof or the intended
disposition to be made of shares of Common Stock upon such exercise.  Promptly
upon receiving such written notice, the Company shall present copies thereof to
counsel for the Company.  If, in the opinion of such counsel, the proposed
transfer of this warrant or disposition of shares may be effected without
registration or qualification (under any federal or state law) of this warrant
or the shares of Common Stock issuable or issued upon the exercise hereof, the
Company, as promptly as practicable, shall notify such holder of such opinion,
whereupon such holder shall be entitled to transfer this warrant, or to exercise
this warrant in accordance with its terms and dispose of the shares received
upon such exercise or to dispose of shares of Common Stock received upon the
previous exercise of this warrant, all in accordance with the terms of the
notice delivered by such holder to the Company, provided that an appropriate
legend in substantially the form set forth at the end of this warrant respecting
the foregoing restrictions on transfer and disposition may be endorsed on this
warrant or the certificates for such shares.

          6.   Subject to the provisions of Section 5, 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 he/it 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 

                                      -4-
<PAGE>
 
on such books, the Company may treat the registered owner hereof as the owner
for all purposes.

          7.   Neither this warrant nor any term hereof may be changed, waived,
discharged or terminated orally but only by an instrument in writing signed by
the party against which enforcement of the change, waiver, discharge or
termination is sought.

          8.   The Company agrees that each time it shall determine to proceed
with the preparation and filing of a registration statement under the Securities
Act it will use all reasonable efforts to allow the inclusion of the Warrant
Shares in such registration statement; provided, however, that the inclusion of
the Warrant Shares in such registration statement shall be subject to the
approval of the managing underwriter and subject to the good faith determination
of the managing underwriter that the inclusion of such Warrant Shares would not
reduce the number of shares to be offered by the Company nor interfere with the
successful marketing of such shares by the Company.

          IN WITNESS WHEREOF, the Company has caused this warrant to be signed
and delivered by a duly authorized officer as of the ____ day of _______, 1996.

- -------- 

          6.1  Representations and Warranties of the Purchaser.  The Purchaser
               -----------------------------------------------                
represents and warrants to the Company that:

          (a)  The Shares, the Warrant, the Conversion Stock and the Warrant
Stock being acquired by the Purchaser hereunder are being purchased for the
Purchaser's own account and not with the view to, or for resale in connection
with, any distribution or public offering thereof within the meaning of the
Securities Act. The Purchaser understands that such securities have not been
registered under the Securities Act by reason of their contemplated issuance in
transactions exempt from the registration and prospectus delivery requirements
of the Securities Act pursuant to Section 4(2) thereof, and that the reliance of
the Company and others upon this exemption from such registration is predicated
in part upon the representations and warranties of the Purchaser contained
herein.  The Purchaser further understands that an exemption from the
registration requirements of the Securities Act with respect to resale of the
securities is not presently available pursuant to Rule 144 promulgated under the
Securities Act by the Commission and that, in any event, the Purchaser may not
sell any Shares pursuant to Rule 144 prior to the expiration of a two-year
period after the Purchaser has acquired the Shares.

          (b)  The principal office of the Purchaser is located at the address
set forth in Section 10.2.  The Purchaser is an "accredited investor" as that
term is defined in Regulation D promulgated under the Securities Act and has
such knowledge and experience in financial and business matters that the
Purchaser is capable of evaluating the merits and risks of the investment to be
made hereunder by the Purchaser.  The Company has made available to the
Purchaser at a reasonable time prior to execution of this Agreement the
opportunity to ask questions and receive answers concerning the terms and
conditions of the sale of the securities contemplated by this Agreement and to
obtain any additional information regarding the Company desired by the
Purchaser.  The Purchaser has utilized such access and opportunity to the extent
believed by the Purchaser to be necessary.

                                      -7-
<PAGE>
 
          (c)  The Purchaser is able to bear the full economic risk of an
investment in the securities.  Despite its high risk and lack of liquidity, an
investment in the securities is suitable for the Purchaser based on the
Purchaser's investment objectives and financial needs and the fact that the
Purchaser has adequate means to provide for the Purchaser's current financial
needs and contingencies and has no need for liquidity of investment with respect
to the Shares.

          (d)  The execution and delivery of this Agreement by the Purchaser has
been duly authorized by all requisite corporate action of the Purchaser and this
Agreement has been duly executed and delivered by the Purchaser.  This Agreement
is a valid and binding obligation of the Purchaser enforceable in accordance
with its terms, except as such enforceability may be limited by bankruptcy,
insolvency, moratorium, reorganization or other similar laws affecting the
enforcement of creditors' rights generally and as to limitations on the
enforcement of the remedy of specific performance and other equitable remedies.

          (e)  No Person has or will have, as a result of any act of or omission
by the Purchaser, any right, interest or claim against the Company for any
commission, fee or other compensation as a finder or broker, or in any similar
capacity, in connection with the transactions contemplated by this Agreement.
The Purchaser will indemnify and hold the Company harmless against any and all
liability to any Person with respect to any such commission, fee or other
compensation which may be payable or determined to be payable in connection with
the transactions between the Purchaser and the Company contemplated by this
Agreement by reason of any acts or omissions of the Purchaser.

          6.2  Restrictions on Transfer.
               ------------------------ 

          (a)  In addition to any legends required under applicable state
securities laws, each certificate representing the Shares shall be endorsed with
the following legend:

               "The securities represented by this certificate may not be
               transferred without (i) the opinion of counsel satisfactory to
               the issuer thereof that such transfer may lawfully be made
               without registration or qualification under the federal
               Securities Act of 1933, as amended, and applicable state
               securities laws or (ii) such registration or qualification."

Upon the conversion of any of the Shares into Conversion Stock, or the exercise
of the Warrant into Warrant Stock unless the Company receives an opinion of
counsel satisfactory to the Company to the effect that a transfer of the
Conversion 

                                      -8-
<PAGE>
 
Stock or the Warrant Stock may thereafter be made without registration, or
unless such Conversion Stock or the Warrant Stock is being disposed of pursuant
to a registration statement filed under the Securities Act, the same legend
shall be endorsed on the certificate evidencing such Conversion Stock or Warrant
Stock.

          (b) Any legend endorsed on a certificate pursuant to Section 6.2(a)
hereof shall be removed, and the Company shall issue a certificate without such
legend to the holder of the securities, if the securities are being disposed of
pursuant to a registration statement filed under the Securities Act or if such
holder provides the Company with an opinion of counsel satisfactory to the
Company to the effect that a transfer of the securities represented by such
certificate may thereafter be made without registration.

Convertible Preferred Stock, par value $.001 per share, of the Company, and any

               "Public Offering" shall mean any offering of Common Shares to the

to an effective registration statement under the Securities Act.

               "Purchasers" shall mean the holders from time to time of the

                ----------------------
time issued or subject to issuance upon the conversion of the Preferred Stock
and exercise of the Warrant and (ii) any additional securities issued with

promulgated under the Securities Act in a

single three-month period by the holder thereof or (w) they shall have ceased to

               "Registration Expenses" shall mean the expenses described in
                ---------------------            
Section 1.6.

               "Securities Act" shall mean the Securities Act of 1933, as

                -------                                                  
Corporation, pursuant to that certain Stock Purchase Agreement with the Company,
dated _____________________________________ , 1996 (the "Stock Purchase
Agreement") to purchase shares of the Company's Common Stock.

          1.2  Demand Registration.   (a) Subject to Section 1.2(d) and Section
               -------------------                                             
1.2(e), if twelve months have elapsed from the date of the Stock Purchase
Agreement and the Company has yet to consummate a Public Offering on Form S-1 or
Form SB-2, and if the Company shall have received a written request therefor
from the record holder or holders of an aggregate of at least 51% of the
Registrable Securities issued or issuable to the holders of Preferred Stock, the
Company shall prepare and file a registration statement under the Securities Act
covering such number of Registrable Securities as are the subject of such
request and shall use its best efforts to cause such registration statement to
become effective; provided, however, that the registration requested pursuant to
this Section 1.2 can only be requested if the Company has not consummated a
Public Offering prior to the requested registration.  Upon the receipt of a
registration request meeting the requirements of this Section 1.2, the Company
shall promptly give written notice to all other record holders of Registrable
Securities that such registration is to be effected.  The Company shall include
in such registration statement such additional Registrable Securities as such
other record holders request within thirty (30) days after the date of the
Company's written notice to them.  If (i) the holders of a majority of the
Registrable Securities for which registration has been requested pursuant to
this Section 1.2 determine for any reason not to proceed with the registration
at any time before the related registration statement has been declared
effective by the Commission, (ii) such registration statement, if theretofore
filed with the Commission, is withdrawn and (iii) the holders of the Registrable
Securities subject to such registration statement agree to bear their own
Registration Expenses incurred in connection therewith and to reimburse the
Company for the Registration Expenses incurred by it in such connection or if
such registration statement, if theretofore filed with the Commission, is
withdrawn at the initiative of the Company, then the holders of the Registrable
Securities shall not be deemed to have exercised their demand registration right
pursuant to this Section 1.2.

                                       2
<PAGE>
 
          (b)  The method of disposition of all Registrable Securities included
in such registration shall be an underwritten offering.  The managing
underwriter of any such offering shall be selected by the Company.  If in the
good faith judgment of the managing underwriter of the Public Offering, the
inclusion of all of the Registrable Securities the registration of which has
been requested would interfere with their successful marketing, the number of
Registrable Securities to be included in the offering shall be reduced, pro
                                                                        ---
rata, among the requesting holders thereof in proportion to the number of
- ----                                                                     
Registrable Securities included in their respective requests for registration.
Registrable Securities that are so excluded from the underwritten Public
Offering shall be withheld by the holders thereof for such period, not exceeding
one hundred and twenty (120) days, that the managing underwriter reasonably
determines is necessary to effect the Offering. The Company shall have the right
to include any securities in a registration statement to be filed as part of a
demand registration pursuant to this Section 1.2.

          (c)  The Company shall be obligated to prepare, file and cause to be
effective only one (1) registration statement pursuant to this Section 1.2.

          (d)  Notwithstanding the foregoing, the Company may delay initiating
the preparation and filing of any registration statement requested pursuant to
this Section 1.2 for a period not to exceed one hundred eighty (180) days if in
the good faith judgment of the Company's Board of Directors effecting the
registration would adversely affect a proposed Public Offering by the Company or
would require the premature disclosure of any financing, acquisition,
disposition of assets or stock, merger or other comparable transaction or would
require the Company to make public disclosure of information the public
disclosure of which would have material adverse effect on the Company.

          (e)  Notwithstanding anything to the contrary contained herein, and
without limitation as to the rights of the Company to include in a demand
registration securities for sale for its own account as provided in Section
1.2(a), at any time within thirty (30) days after receiving a demand for
registration, the Company may elect to effect an underwritten primary
registration in lieu of the requested registration.  If the Company so elects,
the Company shall give prompt written notice to all holders of Registrable
Securities of its intention to effect such a registration and shall afford such
holders the rights contained in Section 1.3 with respect to "piggyback"
registrations.  In such event, the demand for registration shall be deemed to
have been withdrawn.

     1.3  (a)  Piggyback Registration.  If twelve months have elapsed from the
               ----------------------
date of the Stock Purchase Agreement and the Company has yet to consummate a
Public Offering, then each time the Company shall determine to proceed with the
actual preparation and filing of a registration statement under the Securities
Act in connection with the proposed offer and sale for money of any of its

                                       3
<PAGE>
 
securities by it or any of its security holders (other than a registration
statement on Form S-8, Form S-4 or other limited purpose form), the Company will
give written notice of its determination to all record holders of Registrable
Securities. Upon the written request of a record holder of any shares of
Registrable Securities given within 30 days after the date of any such notice
from the Company, the Company will, except as herein provided, cause all the
Registrable Securities the registration of which is requested to be included in
such registration statement, all to the extent requisite to permit the sale or
other disposition by the prospective seller or sellers of the Registrable
Securities to be so registered; provided, however, that nothing herein shall 
                                --------  -------              
prevent the Company from, at any time, abandoning or delaying any registration; 
and provided, further, that if the Company determines not to proceed with a
    --------  -------                                       
registration after the registration statement has been filed with the Commission
and the Company's decision not to proceed is primarily based upon the
anticipated public offering price of the securities to be sold by the Company,
the Company shall promptly complete the registration for the benefit of those
selling security holders who wish to proceed with a Public Offering of their
Registrable Securities and who bear all of the Registration Expenses in excess
of $25,000 incurred by the Company as the result of such registration after the
Company has decided not to proceed. In the discretion of the holders of the
Registrable Securities to be included in the registration (provided that
                                                           --------     
such holders are the record holders of at least 51% of the Registrable
Securities), such registration may count as a demand registration under Section
1.2 (if it otherwise meets the requirements of Section 1.2(a)) for which the
Company will pay the Registration Expenses.

          (b)  If any registration pursuant to this Section 1.3 is underwritten
in whole or in part, the Company may require that the Registrable Securities
included in the registration be included in the underwriting on the same terms
and conditions as the securities otherwise being sold through the underwriters.
If, in the good faith judgment of the managing underwriter of the Public
Offering, the inclusion of all of the Registrable Securities originally covered
by requests for registration would reduce the number of shares to be offered by
the Company or interfere with the successful marketing of the shares offered by
the Company, the number of Registrable Securities to be included in the Offering
may be reduced in the following manner: first, securities held by officers and
                                        -----                                 
directors of the Company (other than Registrable Securities) shall be excluded
from such underwritten public offering to the extent required by the managing
underwriter, second, any securities, other than Registrable Securities, proposed
             ------                                                             
to be sold in the Offering by persons other than the Company shall be excluded
and third, if a further reduction in the Offering is required, the Registrable
    -----                                                                     
Securities requested to be included in the Offering shall be reduced, pro rata,
                                                                      --- ---- 
among the requesting holders thereof in proportion to the number of Registrable
Securities included in their respective requests for registration.  The
Registrable Securities which are thus excluded from the underwritten Public
Offering shall be withheld from the market 

                                       4
<PAGE>
 
by the holders thereof for a period which the managing underwriter reasonably
determines is necessary in order to effect the Public Offering.

          1.4  Short Form Registration.  In addition to the registration rights
               -----------------------                                         
provided in Sections 1.2 and 1.3, if the Company qualifies for the use of Form
S-3 (or any similar registration form), the Company shall at the request of
holders of Registrable Securities from time to time register Registrable
Securities on behalf of such holder or holders on such form; provided, however,
                                                             --------  ------- 
that the Company shall not be required to accommodate any request to register
less than 100,000 Registrable Securities nor to accommodate more than two of
such registrations in any calendar year.  The Company shall give notice of any
proposed Form S-3 registration to the record holders of Registrable Securities
who did not join in the request therefor and afford them a reasonable
opportunity to do so.

          1.5  Registration Procedures.  If and whenever the Company is required
               -----------------------                                          
by the provisions of Sections 1.2 and 1.3 or 1.4 to effect the registration of
shares of Registrable Securities under the Securities Act, the Company will use
its best efforts to effect the registration and sale of such Registrable
Securities in accordance with the intended methods of disposition specified by
the holders participating therein.  Without limiting the foregoing, the Company
in each such case will, as expeditiously as possible,:

          (a)  prepare and file with the Commission (in the case of a demand
     registration pursuant to Section 1.2 or Section 1.4) the requisite
     registration statement to effect such registration (including such audited
     financial statements as may be required by the Securities Act or the rules
     and regulations promulgated thereunder) and use its best efforts to cause
     such registration statement to become effective; provided, however, that as
                                                      --------  -------
     far in advance as practical before filing such registration statement or
     any amendment thereto, the Company will furnish to counsel for the
     requesting holders copies of reasonably complete drafts of all such
     documents proposed to be filed (including exhibits), and any such holder
     shall have the opportunity to object to any information pertaining solely
     to such holder that is contained therein and the Company will make the
     corrections reasonably requested by such holder with respect to such
     information prior to filing any such registration statement or amendment;

            (b) prepare and file with the Commission such amendments and
     supplements to such registration statement and any prospectus used in
     connection therewith as may be necessary to maintain the effectiveness of
     such registration statement and to comply with the provisions of the
     Securities Act with respect to the disposition of all Registrable
     Securities included in such registration statement, in accordance with the
     intended methods of disposition thereof, until the earlier of (i) such time
     as all of such 

                                       5
<PAGE>
 
     securities have been disposed of in accordance with the
     intended methods of disposition by the seller or sellers thereof set forth
     in such registration statement and (ii) one hundred eighty (180) days after
     such registration statement becomes effective;

          (c) promptly notify each requesting holder and the underwriter or
     underwriters, if any:

              (i)   when such registration statement or any prospectus used in
          connection therewith, or any amendment or supplement thereto, has been
          filed and, with respect to such registration statement or any post-
          effective amendment thereto, when the same has become effective;

              (ii)  of any written request by the Commission for amendments or
          supplements to such registration statement or prospectus;

              (iii) of the notification to the Company by the Commission of its
          initiation of any proceeding with respect to the issuance by the
          Commission of, or of the issuance by the Commission of, any stop order
          suspending the effectiveness of such registration statement; and

              (iv)  of the receipt by the Company of any notification with
          respect to the suspension of the qualification of any Registrable
          Securities for sale under the applicable securities or blue sky laws
          of any jurisdiction;

          (d)  furnish to each seller of Registrable Securities included in such
     registration statement such number of conformed copies of such registration
     statement and of each amendment and supplement thereto such number of
     copies of the prospectus contained in such registration statement
     (including each preliminary prospectus and any summary prospectus) and any
     other prospectus filed under Rule 424 promulgated under the Securities Act
     relating to such seller's Registrable Securities, and such other documents,
     as such seller may reasonably request to facilitate the disposition of its
     Registrable Securities;

          (e)  use its best efforts to register or qualify all Registrable
     Securities included in such registration statement under such other
     securities or blue sky laws of such jurisdictions as each holder of
     Registrable Securities thereof shall reasonably request within twenty (20)
     days following the original filing of such registration statement and to
     keep such registration or qualification in effect for so long as such
     registration statement remains in effect, and take any 

                                       6
<PAGE>
 
     other action which may be reasonably necessary or advisable to enable such
     holder to consummate the disposition in such jurisdictions of the
     Registrable Securities owned by such holder, except that the Company shall
     not for any such purpose be required (i) to qualify generally to do
     business as a foreign corporation in any jurisdiction wherein it would not
     but for the requirements of this paragraph (e) be obligated to be so
     qualified, (ii) to consent to general service of process in any such
     jurisdiction or (iii) to subject itself to taxation in any such
     jurisdiction by reason of such registration or qualification;

          (f)  use its best efforts to cause all Registrable Securities included
     in such registration statement to be registered with or approved by such
     other governmental agencies or authorities as may be necessary to enable
     each holder thereof to consummate the disposition of such Registrable
     Securities;

          (g)  If and to the extent any of the following are obtained by or
     furnished to the Company or the underwriters, furnish to any holder who so
     requests a signed counterpart, addressed to such holder (and the
     underwriters, if any), of

               (i)    an opinion of counsel for the Company, dated the effective
          date of such registration statement (or, if such registration includes
          an underwritten Public Offering, dated the date of any closing under
          the underwriting agreement), and

               (ii)   a "cold comfort" letter, dated the effective date of such
          registration statement (and, if such registration includes an
          underwritten Public Offering, dated the date of any closing under the
          underwriting agreement), signed by the independent public accountants
          who have certified the Company's financial statements included in such
          registration statement;

     provided, however, that the obligation to furnish a "cold comfort" letter
     --------  -------                                                 
     shall only be imposed to the extent permitted under any then-prevailing
     rules of accounting procedure;

          (h)  notify each holder whose Registrable Securities are included in
     such registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the Securities Act, of the happening of
     any event as a result of which any prospectus included in such registration
     statement, as then in effect, includes an untrue statement of a material
     fact or omits to state any material fact required to be stated therein or
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading, and at the request of any such
     holder promptly prepare and furnish to such holder a reasonable number of
     copies 

                                       7
<PAGE>
 
     of a supplement to or an amendment of such prospectus as may be
     necessary so that, as thereafter delivered to the purchasers of such
     securities, such prospectus shall not include an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

          (i)  otherwise use its best efforts to comply with applicable rules
     and regulations of the Commission;

          (j)  provide a transfer agent and registrar for all Registrable
     Securities included in such registration statement not later than the
     effective date of such registration statement; and

          (k)  use its best efforts to cause all Registrable Securities included
     in such registration statement to be listed, upon official notice of
     issuance, on any securities exchange or quotation system on which any of
     the securities of the same class as the Registrable Securities are then
     listed.

          (l)  The Company may require each holder whose Registrable securities
     are being registered to, and each such holder, as a condition to including
     Registrable Securities in such registration, shall, furnish the Company and
     the underwriters with such information and affidavits regarding such holder
     and the distribution of such securities as the Company and the underwriters
     may from time to time reasonably request in writing in connection with such
     registration. At any time during the effectiveness of any registration
     statement covering Registrable Securities offered by a holder, if such
     holder becomes aware of any change materially affecting the accuracy of the
     information contained in such registration statement or the prospectus (as
     then amended or supplemented) relating to such holder, it will immediately
     notify the Company of such change.

          (m)  Upon receipt of any notice from the Company of the happening of
     any event of the kind described in paragraph (h) of this Section 1.5, each
     holder will forthwith discontinue such holder's disposition of Registrable
     Securities pursuant to the registration statement relating to such
     Registrable Securities until such holder receives the copies of the
     supplemented or amended prospectus contemplated by paragraph (h) of this
     Section 1.5 and, if so directed by the Company, shall deliver to the
     Company all copies, other than permanent file copies, then in such holder's
     possession of the prospectus relating to such Registrable Securities
     current at the time of receipt of such notice.

to the number of Registrable Securities being sold by them.

          1.7  Indemnification.
               --------------- 

               (a)  The Company will, to the full extent permitted by law,
     indemnify and hold harmless each holder of Registrable Securities which are
     included in a registration statement pursuant to the provisions of this
     Section 1 and its directors, officers and partners and each other person,
     if any, who controls such holder within the meaning of the Securities Act
     from and against any and all losses, claims, damages, expenses or
     liabilities, joint or several (collectively, "Losses") to which such holder
     or any such director, officer, partner or controlling person may become
     subject under the Securities Act or otherwise, insofar as such Losses (or
     actions or proceedings, whether commenced or threatened, in respect
     thereof) arise out of or are based upon any untrue statement or alleged
     untrue statement of any material fact contained in a registration statement
     prepared and filed hereunder, any preliminary, final or summary prospectus
     contained therein or any amendment or supplement thereto or any omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make

                                       9
<PAGE>
 
     the statements therein (in the case of a prospectus, in light of the
     circumstances in which they were made) not misleading and the Company will
     reimburse the holder and each such director, officer, partner and
     controlling person for any legal or other expenses reasonably incurred by
     them in connection with investigating or defending against any such Losses
     (or action or proceeding in respect thereof); provided, however, that the
                                                   --------  -------          
     Company will not be liable in any such case to the extent that any such
     Losses arise out of or are based upon (i) an untrue statement or alleged
     untrue statement or omission or alleged omission made in conformity with
     written information furnished by such holder specifically for use in the
     preparation of the registration statement or (ii) such holder's failure to
     send or give a copy of the final prospectus to the persons asserting an
     untrue statement or alleged untrue statement or omission or alleged
     omission at or prior to the written confirmation of the sale of Registrable
     Securities to such person if such statement or omission was corrected in
     such final prospectus. Such indemnity shall remain in full force and effect
     regardless of any investigation made by or on behalf of such holder or any
     such director, officer, partner or controlling person of such holder and
     shall survive the transfer of such securities by such holder. The Company
     shall also indemnify each other person who participates (including as an
     underwriter) in the offering or sale of Registrable Securities, their
     officers and directors, and partners, and each other person, if any, who
     controls any such participating person within the meaning of the Securities
     Act to the same extent as provided above with respect to holders of
     Registrable Securities.

               (b)  Each holder of shares of Registrable Securities which are
     included in a registration pursuant to the provisions of this Section 1
     will, to the full extent permitted by law, indemnify and hold harmless the
     Company, its officers, directors and each other person, if any, who
     controls the Company within the meaning of the Securities Act from and
     against any and all Losses to which the Company or any such officer,
     director or controlling person may become subject under the Securities Act
     or otherwise, insofar as such Losses (or actions or proceedings, whether
     commenced or threatened, in respect thereof) arise out of or are based upon
     any untrue or alleged untrue statement of any material fact contained in a
     registration statement prepared and filed hereunder, any preliminary, final
     or summary prospectus contained therein or any amendment or supplement
     thereto, or arise out of or are based upon the omission or the alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statements therein (in the case of a prospectus, in
     the light of the circumstances under which they were made) not misleading,
     in each case to the extent, but only to the extent, that such untrue
     statement or alleged untrue statement or omission or alleged omission was
     so made in reliance upon and in strict conformity with written information
     furnished by such holder specifically for use in the preparation 

                                      10
<PAGE>
 
     of such registration statement. Such indemnity shall remain in full force
     and effect regardless of any investigation made by or on behalf of the
     Company or any such director, officer or controlling person of the Company.
     The holder of Registrable Securities included in a registration statement
     shall also indemnify each other person who participates (including as an
     underwriter) in the offering or sale of Registrable Securities, their
     officers and directors, and partners, and each other person, if any, who
     controls any such participating person within the meaning of the Securities
     Act to the same extent as provided above with respect to the Company. In no
     event shall the liability of any holder under this Section 1.7(b) exceed
     the net proceeds received by such holder from the sale of their Registrable
     Securities.

               (c)  Promptly after receipt by an indemnified party pursuant to
     the provisions of paragraph (a) or (b) of this Section 1.7 of notice of the
     commencement of any action involving the subject matter of the foregoing
     indemnity provisions, such indemnified party will, if a claim thereof is to
     be made against the indemnifying party pursuant to the provisions of
     paragraph (a) or (b), promptly notify the indemnifying party of the
     commencement thereof; but the omission to so notify the indemnifying party
     will not relieve the indemnifying party from any liability which it may
     have to any indemnified party except to the extent that the indemnifying
     party is actually prejudiced by such failure to give notice. In case any
     such action is brought against any indemnified party, the indemnifying
     party shall have the right to participate in, and, to the extent that it
     may wish, jointly with any other indemnifying party, to assume the defense
     thereof, with counsel reasonably satisfactory to such indemnified party;
     provided, however, that if the defendants in any action include both the
     --------  -------
     indemnified party and the indemnifying party and the indemnified party
     reasonably concludes that there is a conflict of interest that would
     prevent counsel for the indemnifying party from also representing the
     indemnified party, the indemnified party shall have the right to select
     separate counsel to participate in the defense of such action on behalf of
     the indemnified party or parties. After notice from the indemnifying party
     to such indemnified party of its election so to assume the defense thereof,
     the indemnifying party will not be liable to such indemnified party
     pursuant to the provisions of said paragraph (a) or (b) for any legal or
     other expense subsequently incurred by such indemnified party in connection
     with the defense thereof unless (i) the indemnified party shall have
     employed counsel in accordance with the proviso of the preceding sentence,
     (ii) the indemnifying party shall not have employed counsel reasonably
     satisfactory to the indemnified party to represent the indemnified party
     within a reasonable time after the notice of the commencement of the action
     or (iii) the indemnifying party has authorized the employment of counsel
     for the indemnified party at the expense of the indemnifying party. If the
     indemnifying party is not entitled to, or elects not to, assume the defense
     
                                      11
<PAGE>
 
     of a claim, it will not be obligated to pay the fees and expenses of more
     than one counsel for the indemnified parties with respect to such claim,
     unless in the reasonable judgment of any indemnified party a conflict of
     interest may exist between such indemnified party and any other indemnified
     parties with respect to such claim, in which event the indemnifying party
     shall be obligated to pay the fees and expenses of additional counsel or
     counsels for the indemnified parties. No indemnifying party shall consent
     to entry of any judgment or enter into any settlement which does not
     include as an unconditional term thereof the giving by the claimant or
     plaintiff to such indemnified party of a release from all liability in
     respect to such claim or litigation without the consent of the indemnified
     party. No indemnifying party shall be subject to any liability for any
     settlement made without its consent. An indemnified party may at any time
     elect to participate in the defense of any claim or proceeding at its own
     expense.

          1.8  Covenants Relating to Rule 144.  If at any time the Company is
               ------------------------------                                
required to filed reports in compliance with either Section 13 or Section 15(d)
of the Securities Exchange Act of 1934, as amended, (the "Exchange Act") the
Company will (a) file reports in compliance with the Exchange Act and (b) comply
with all rules and regulations of the Commission applicable to the use of Rule
144.

          1.9  Underwritten Offerings.  If a distribution of Registrable
               ----------------------                                   
Securities pursuant to a registration statement is to be underwritten, the
holders whose Registrable Securities are to be distributed by such underwriters
shall be parties to such underwriting agreement.  No requesting holder may
participate in such underwritten offering unless such holder agrees to sell its
Registrable Securities on the basis provided in such underwriting agreement and
completes and executes all questionnaires, powers of attorney, indemnities and
other documents reasonably required under the terms of such underwriting
agreement.  If any requesting holder disapproves of the terms of an
underwriting, such holder may elect to withdraw therefrom and from such
registration by notice to the Company and the managing underwriter, and each of
the remaining requesting holders shall be entitled to increase the number of
Registrable Securities being registered to the extent of the Registrable
Securities so withdrawn in the proportion which the number of Registrable
Securities being registered by such remaining requesting holder bears to the
total number of Registrable Securities being registered by all such remaining
requesting holders.

          1.10 Stand-Off Agreement.  Each holder of Registrable Securities
               -------------------                                        
agrees, so long as such holder holds at least 1% of the Company's outstanding
voting equity securities, in connection with the Company's initial Public
Offering, upon request of the Company or the underwriters managing such
Offering, not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any Common Shares of the Company other than
those included in the 

                                      12
<PAGE>
 
registration without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not exceeding 180
days) from the effective date of such registration as may be requested by the
underwriters; provided, however, that all other holders of at least 1% of the
              --------  -------                              
Company's outstanding voting equity securities and all of the officers and
directors of the Company who own stock of the Company must also agree to not
less onerous restrictions.

          1.11 Amendment of Registration Rights.  Without the written consent
               --------------------------------

the Company shall not amend this Exhibit C, or enter into any agreement with any
holder or prospective holder of any securities of the Company which would allow
such holder or prospective holder to include such securities as Registrable
Securities under this Exhibit C.  Any amendment to this Section 1 pertaining
only to rights of a particular series of the Company's outstanding Preferred
Stock and affecting such rights adversely and in a manner materially different
from its effect on the rights of the other outstanding series of the Preferred
Stock must be approved by the holders of more than 50% of the outstanding shares
of such series of Preferred Stock.

          1.12 Termination.  This Exhibit C, and all of the Company's
               -----------                                           
obligations (other than its obligations pursuant to Section 1.7, which Section
shall survive such termination) hereunder, shall terminate upon the earlier to
occur of (i) the date there are no Registrable Securities outstanding and (ii)
the fifth anniversary of the effective date of the registration statement filed
with respect to the Company's initial Public Offering.

conditions:

          1.   The rights represented by this warrant may be exercised by the
holder hereof, in whole or in part, by written notice of exercise delivered to

by the surrender of this warrant (properly endorsed if required) at the

restrictive legend set forth at the end of this warrant, shall be delivered to
the holder within fifteen (15) days after the rights represented by this warrant

          3.   The warrant exercise price shall be subject to adjustment from
time to time as hereinafter provided in this section 3.

          (a)  If the Company at any time following the conversion of the series

Company pursuant to that certain Stock Purchase Agreement, dated
                                                               ----------------
, 1996 (the "Stock Purchase Agreement") into shares of Common Stock 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 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

reorganization, reclassification, consolidation, merger or sale, the holder of
this warrant shall have the right to purchase and receive upon the basis and
upon the terms and conditions specified in this warrant and in lieu of the
shares of the common stock of the Company immediately theretofore purchasable
and receivable upon the exercise of the rights represented hereby, such shares
of stock, other securities or assets as would have been issued or delivered to
the holder of this warrant if it had exercised this warrant and had received
such shares of common stock prior to such 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 the registered holder of this
warrant at the last address of such holder appearing on the books of the
Company, the obligation to deliver to such holder such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to purchase.

          (c)  If when the Preferred Stock is converted into Common Stock and

shares of common stock issuable upon the exercise hereof or the intended

transfer of this warrant or disposition of shares may be effected without
registration or qualification (under any federal or state law) of this warrant
or the shares of common stock issuable or issued upon the exercise hereof, the
Company, as promptly as practicable, shall notify such holder of such opinion,
whereupon such holder shall be entitled to transfer this warrant, or to exercise

          ----------------------------------------------               
represents and warrants to the Company as follows:

          (a)  That the Investor is in a financial position to hold the Units
     for an indefinite period of time and is able to bear the economic risk and
     withstand a complete loss of the Investor's investment in the Units;

          (b)  That the Investor believes the Investor, either alone or with the
     assistance of the Investor's own professional advisor, has such knowledge
     and experience in financial and business matters that the Investor is
     capable of reading and interpreting financial statements and evaluating the
     merits and risks of the prospective investment in the Units and has the net
     worth to undertake such risks;

          (c)  That the Investor has obtained, to the extent the Investor deems
     necessary, the Investor's own personal professional advice with respect to
     the risks inherent in the investment in the Units and the suitability of an
     investment in the Units in light of the Investor's financial condition and
     investment needs;

          (d)  That the Investor believes that the investment in the Units is
     suitable for the Investor based upon the Investor's investment objectives
     and financial needs, and the Investor has adequate means for providing for
     the Investor's current financial needs and personal contingencies and has
     no need for liquidity of investment with respect to the Units;

     information regarding the Company and has utilized such access to the
     Investor's satisfaction for the purpose of obtaining information and,

     purpose of asking questions of, and receiving answers from, such
     representatives concerning the Company and to obtain any additional
     information, to the extent reasonably available, necessary to verify the
     accuracy of information provided to the Investor;

     a long-term investment; (ii) the purchaser of the Units must bear the
     economic risk of investment for an indefinite period of time because the
     Notes, Warrants and Warrant Stock have not been registered under the
     Securities Act or under the securities laws of any state and, therefore,
     none of such securities can be sold unless they are subsequently registered
     under said laws or exemptions from such registrations are available; (iii)
     the Investor may not be able to liquidate the Investor's investment in the
     event of an emergency or pledge any of such securities as collateral for

     3406(a)(i)(C) of the Internal Revenue Code of 1986, as amended (Note: You
     are subject to backup withholding if (i) you fail to furnish your Social
     Security number or taxpayer identification number herein; (ii) the Internal
     Revenue Service notifies the Company that you furnished an incorrect Social
     Security number or taxpayer identification number; (iii) you are notified
     that you are subject to backup withholding; or (iv) you fail to certify
     that you are not subject to backup withholding or you fail to certify your
     Social Security number or taxpayer identification number);

          (j)  That the Investor is a bona fide resident of, is domiciled in,
     and received the offer and made the decision to invest in the Units in, the
     state set forth on the signature page below under "Addresses" and that the
     Units are being purchased by the Investor in the Investor's name solely for
     the Investor's own beneficial interest and not as nominee for, or on behalf
     of, or for the beneficial interest of, or with the intention to transfer
     to, any other person, trust or organization.

                                    WARRANT
                                      FOR
                             SHARES OF COMMON STOCK
                                       OF
                            FIELDWORKS, INCORPORATED

          FOR VALUE RECEIVED, ________________ or its successors or assigns
("Holder"), is hereby entitled to subscribe for and purchase from Fieldworks,
Incorporated, a Minnesota corporation (the "Company"), up to the total number of
Warrant Shares (as calculated pursuant to Section 3(A)) of fully paid and
nonassessable shares of the Company's Common Stock, or such greater or lesser
number of such shares as may be determined by application of the anti-dilution
provisions of this warrant, at an exercise price per share equal to 80% of the
price per share received by the Company in its next sale of equity securities
with gross proceeds of $2.5 million or more (the "Warrant Exercise Price").

          This warrant may be exercised by Investor at any time after the
initial public offering of the Company's Common Stock is effective until a date
on or prior to three years from the date hereof.

          This warrant is subject to the following provisions, terms and
conditions:

          1.   (a)  The rights represented by this warrant may be exercised by
the holder hereof, in whole or in part, by written notice of exercise delivered
to the Company at least twenty (20) days prior to the intended date of exercise
and by the surrender of this warrant (properly endorsed if required) at the
principal office of the Company and upon payment to it by cash, certified check
or bank draft of the purchase price for such shares or by exercise of the
Conversion Right as provided in (b) below.  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 Company of the Warrant Exercise
Price unless the Conversion Right has been exercised.  Certificates for the
shares of stock so purchased, bearing the restrictive legend set forth at the
end of this warrant, shall be delivered to the 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 has not been exercised shall
also be delivered to the holder hereof within such time.  No fractional shares
shall be issued upon the exercise of this warrant.

               (b)  In lieu of payment, the rights represented by this warrant
may also be exercised by a written notice of exercise specifying that the
Investor wishes to convert all of this warrant (the "Conversion Right") into
that number of shares of Common Stock as follows: the number of shares of Common
Stock equal to the quotient obtained by dividing (x) the value of the shares
subject to the warrant 
<PAGE>
 
(determined by subtracting the aggregate warrant exercise price in effect
immediately prior to the exercise of the Conversion Right from the aggregate
fair market value of the shares of Common Stock issuable upon exercise of this
warrant immediately prior to the exercise of the Conversion Right) by (y) the
fair market value of one share of Common Stock immediately prior to the exercise
of the Conversion Right. For purposes of this section 1(b), the fair market
value of a share of Common Stock as of a particular date (the "Determination
Date") shall mean:

               (i)  If the Company's Common Stock is traded on an exchange or is
          quoted on the National Association of Securities Dealers, Inc.
          Automated Quotation ("NASDAQ") National Market System, then the
          closing or last sale price, respectively, reported for the business
          day immediately preceding the Determination Date.

               (ii) If the Company's Common Stock is not traded on an exchange
          or on the NASDAQ National Market System but is quoted on NASDAQ, then
          the mean of the closing bid and asked prices reported for the business
          day immediately preceding the Determination Date.

          2.   The Company covenants and agrees that 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.
The Company further covenants and agrees that during the period within which the
rights represented by this warrant may be exercised, the Company will 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.

          3.   This warrant shall be exercisable for the number of Warrant
Shares, as adjusted, as provided for in this Section 3(A), and subject to
adjustment from time to time as provided in this Section 3(B).

     (A)  Warrant Shares: Subject to adjustment under this Section 3, the number
          --------------
of Warrant Shares which may be purchased by the holder of this warrant shall be
equal to:

                    10% x $                         = Warrant Shares
     -----------------------------------------
             Warrant Exercise Price per share

     (B)  Anti-dilution:
          --------------

               (i)  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 


<PAGE>
 
          combination shall be proportionately adjusted to reflect the reduction
          or increase in the value of each such share.

               (ii)   If any 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 shares, then, as a condition of such reorganization,
          reclassification, consolidation, merger or sale, the holder of this
          warrant shall have the right to purchase and receive upon the basis
          and upon the terms and conditions specified in this warrant and in
          lieu of the shares of the Common Stock of the Company immediately
          theretofore purchasable and receivable upon the exercise of the rights
          represented hereby, such shares of stock, other securities or assets
          as would have been issued or delivered to the holder of this warrant
          if it had exercised this warrant and had received such shares of
          Common Stock prior to such 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 the registered holder of this warrant at the last address of
          such holder appearing on the books of the Company, the obligation to
          deliver to such holder such shares of stock, securities or assets as,
          in accordance with the foregoing provisions, such holder may be
          entitled to purchase.

               (iii)  If the Company takes any other action, or if any other
          event occurs, which does not come within the scope of the provisions
          of Section 3(B)(i) or (ii), but which should result in an adjustment
          in the Warrant Exercise Price and/or the number of shares subject to
          this warrant in order to fairly protect the purchase rights of the
          holder of this warrant, an appropriate adjustment in such purchase
          rights shall be made by the Company.

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

               (v)    Upon any adjustment of the Warrant Exercise Price, the
          Company shall give written notice thereof, by first class mail,
          postage prepaid, addressed to the registered holder of this warrant at
          the address of such holder 


<PAGE>
 
          as shown on the books of the Company, which notice shall state the
          Warrant Exercise Price resulting from such adjustment and the increase
          or decrease, if any, in the number of shares purchasable at such price
          upon the exercise of this warrant, setting forth in reasonable detail
          the method of calculation and the facts upon which such calculation is
          based.

          4.   This warrant shall not entitle the holder hereof to any voting
rights or other rights as a shareholder of the Company.

          5.   The holder of this warrant, by acceptance hereof, agrees to give
written notice to the Company before transferring this warrant or transferring
any shares of the Company's Common Stock issuable or issued upon the exercise of
this warrant of the holder's intention to do so, describing briefly the manner
of any proposed transfer of this warrant or such holder's intention as to the
shares of Common Stock issuable upon the exercise hereof or the intended
disposition to be made of shares of Common Stock upon such exercise.  Promptly
upon receiving such written notice, the Company shall present copies thereof to
counsel for the Company.  If, in the opinion of such counsel, the proposed
transfer of this warrant or disposition of shares may be effected without
registration or qualification (under any federal or state law) of this warrant
or the shares of Common Stock issuable or issued upon the exercise hereof, the
Company, as promptly as practicable, shall notify such holder of such opinion,
whereupon such holder shall be entitled to transfer this warrant, or to exercise
this warrant in accordance with its terms and dispose of the shares received
upon such exercise or to dispose of shares of Common Stock received upon the
previous exercise of this warrant, all in accordance with the terms of the
notice delivered by such holder to the Company, provided that an appropriate
legend in substantially the form set forth at the end of this warrant respecting
the foregoing restrictions on transfer and disposition may be endorsed on this
warrant or the certificates for such shares.

          6.   Subject to the provisions of Section 5, 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 he/it 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.

          7.   Neither this warrant nor any term hereof may be changed, waived,
discharged or terminated orally but only by an instrument in writing signed 
<PAGE>
 
by the party against which enforcement of the change, waiver, discharge or
termination is sought.

          8.   The Company agrees that each time it shall determine to proceed
with the preparation and filing of a registration statement under the Securities
Act it will use all reasonable efforts to allow the inclusion of the Warrant
Shares in such registration statement; provided, however, that the inclusion of
the Warrant Shares in such registration statement shall be subject to the
approval of the managing underwriter and subject to the good faith determination
of the managing underwriter that the inclusion of such Warrant Shares would not
reduce the number of shares to be offered by the Company nor interfere with the
successful marketing of such shares by the Company.

          IN WITNESS WHEREOF, the Company has caused this warrant to be signed
and delivered by a duly authorized officer as of the _____ day of September,
1996.

     WHEREAS, in connection with such postponement, Brightstone Capital and
certain of its affiliates have requested, and the Company has agreed, to adjust
the exercise price under certain warrants issued in connection with such loans,
including the Warrant.

     WHEREAS, Section 7 of the Warrant provides that the Warrant and the terms
thereof may be changed only by an instrument in writing.

$__________ and the Company agrees to deliver to the Investor a subordinated
promissory note, in the form attached hereto as Exhibit A (the "Note" and,
                                                ---------                 
together with any similar notes issued to Other Investors, the "Notes"), in a

of funds to the Company in the amount set forth above.  Up to 20% of the
original principal amount of the Note shall be convertible into shares of Common
Stock (the "Conversion Shares") at Investor's option, as more fully described in
the Note.

          2.   Warrants.  In consideration of the loan, the Company shall issue

Common Stock of the Company for each $50,000 loaned to the Company.  For
incremental amounts loaned over $50,000, the Warrant shall cover that number of
shares of Common Stock obtained by multiplying 2,500 by a fraction, the
numerator of which is the incremental amount loaned and the denominator of which
is 50,000.  The shares of Common Stock issuable upon exercise of the Warrant are
referred to hereinafter as the "Warrant Shares."

          3.   Repayment.  All outstanding principal and accrued interest on the

     binding agreement on the part of the Company;

          (c) That, as of the date hereof, this Agreement, the Note, the Warrant
     and the Company's Confidential Private Placement Memorandum dated December
     4, 1996 (together with all exhibits thereto and documents delivered
     therewith, the "Memorandum"), taken as a whole, do not contain an untrue
     statement of a material fact or omit to state a material fact required in
     light of the circumstances under which such statements were made to be

     with the Memorandum;

          (b)  That the Investor is in a financial position to hold the Units
     for an indefinite period of time and is able to bear the economic risk and
     withstand a complete loss of the Investor's investment in the Units;

                                      -2-
<PAGE>
 
               (c)  That the Investor believes the Investor, either alone or
          with the assistance of the Investor's own professional advisor, has
          such knowledge and experience in financial and business matters that
          the Investor is capable of reading and interpreting financial
          statements and evaluating the merits and risks of the prospective
          investment in the Units and has the net worth to undertake such risks;

               (d)  That the Investor has obtained, to the extent the Investor
          deems necessary, the Investor's own personal professional advice with
          respect to the risks inherent in the investment in the Units and the
          suitability of an investment in the Units in light of the Investor's
          financial condition and investment needs;

               (e)  That the Investor believes that the investment in the Units
          is suitable for the Investor based upon the Investor's investment
          objectives and financial needs, and the Investor has adequate means
          for providing for the Investor's current financial needs and personal
          contingencies and has no need for liquidity of investment with respect
          to the Units;

               (f)  That the Investor has been given access to full and complete
          information regarding the Company and has utilized such access to the

          particularly, the Investor has either attended or been given
          reasonable opportunity to attend a meeting with representatives of the
          Company for the purpose of asking questions of, and receiving answers
          from, such representatives concerning the Company and to obtain any

          to verify the accuracy of information provided to the Investor;

               (g)  That the Investor recognizes that an investment in the Units
          involves a high degree of risk, including, but not limited to, the
          risk of economic losses from operations of the Company;

               (h) That the Investor recognizes that in addition to the proceeds
          from the sale of Units, the Company will require additional financing
          to fund current and proposed operations, and there can be no
          assurances that additional financing can be obtained;

               (i)  That the Investor realizes that (i) the purchase of the
          Units is a long-term investment; (ii) the purchaser of the Units must
          bear the economic risk of investment for an indefinite period of time
          because the Notes, the Warrant, the Warrant Shares and the Conversion
          Shares have not been registered under the Securities Act or under the
          securities laws of any state and, therefore, none of such securities
          can be sold unless they are 

                                      -3-
<PAGE>
 
          subsequently registered under said laws or exemptions from such
          registrations are available; (iii) the Investor may not be able to
          liquidate the Investor's investment in the event of an emergency or
          pledge any of such securities as collateral for loans; and (iv) the
          transferability of such securities is restricted and (A) requires the
          written consent of the Company, and (B) legends will be placed on the
          Notes and the Warrant and on any certificates representing the Warrant
          Shares and the Conversion Shares referring to the applicable
          restrictions on transferability.

               (j)  That the Investor certifies, under penalties of perjury,
          that the Investor is NOT subject to the backup withholding provisions
          of Section 3406(a)(i)(C) of the Internal Revenue Code of 1986, as
          amended (Note: You are subject to backup withholding if (i) you fail
          to furnish your Social Security number or taxpayer identification
          number herein; (ii) the Internal Revenue Service notifies the Company
          that you furnished an incorrect Social Security number or taxpayer
          identification number; (iii) you are notified that you are subject to
          backup withholding; or (iv) you fail to certify that you are not
          subject to backup withholding or you fail to certify your Social
          Security number or taxpayer identification number); and

               (k)  That the Investor is a bona fide resident of, is domiciled
          in, and received the offer and made the decision to invest in the
          Units in, the state set forth on the signature page below under
          "Addresses" and that the Units are being purchased by the Investor in
          the Investor's name solely for the Investor's own beneficial interest
          and not as nominee for, or on behalf of, or for the beneficial
          interest of, or with the intention to transfer to, any other person,
          trust or organization.

     9.   Registration Rights.
          ------------------- 

          (a) Each time the Company shall determine to proceed with the actual
     preparation and filing of a registration statement under the Securities 

                                      -6-
<PAGE>
 
     Act in connection with the proposed offer and sale for money of any of its
     securities by it, the Company will give written notice of its determination
     to Investor. Upon the written request of Investor given within 30 days
     after the date of mailing of any such notice from the Company, the Company
     will, except as herein provided, cause all the Warrant Shares and
     Conversion Shares issued and to be issued upon exercise of the Warrants and
     conversion of the Notes requested by such holders to be registered, to be
     included in such registration statement, all to the extent requisite to
     permit the sale or other disposition by Investor of the shares to be so
     registered; provided, however, that nothing herein shall prevent the
     Company from, at any time, abandoning or delaying any such registration
     initiated by it. If any such registration shall be underwritten in whole or
     in part, the Company may require that the shares requested for inclusion by
     Investor pursuant to this paragraph (a) be included in the underwriting on
     the same terms and conditions as the securities otherwise being sold
     through the underwriters. If in the good faith judgment of the managing
     underwriter of such public offering the inclusion of all of the shares
     originally covered by a request for registration made by Investor would
     reduce the number of shares to be offered by the Company or interfere with
     the successful marketing of the shares of stock offered by the Company, the
     number of shares owned by Investor and otherwise to be included in the
     underwritten public offering may be reduced; provided, however, that any
     such required reduction shall be pro rata among all persons (other than the
     Company) who are participating in such offering. Those shares which are
     thus excluded from such underwritten public offering shall be withheld from
     the market by Investor for a period, not to exceed 90 days, which the
     managing underwriter reasonably determines is necessary in order to effect
     the underwritten public offering.

          (b) Further, on a one-time basis only, after the first anniversary of
     the Effective Date, upon request by the holders of a majority in interest
     of the Warrants, Warrant Shares and Conversion Shares held by Investor and
     the Other Investors, the Company will promptly take all necessary steps to
     register or qualify on Form S-3 (or any successor form thereto) under the
     Securities Act and the securities laws of such states as the holders may
     reasonably request (provided, that the Company shall not for any purpose be
     required to execute a general consent to service of process or to qualify
     to do business as a foreign corporation in any jurisdiction wherein it is
     not so qualified), the Warrant Shares and Conversion Shares issued and to
     be issued upon exercise of the Warrants and conversion of the Notes
     requested by such holders to be registered or qualified in their request to
     the Company. The Company shall keep effective and maintain any
     registration, qualification, notification or approval specified in this
     paragraph (b) for nine months to provide such holders time to dispose
     thereof and from time to time shall 

                                      -7-
<PAGE>
 
     amend or supplement the prospectus used in connection therewith to the
     extent necessary in order to comply with applicable law.

          (c) With respect to each inclusion of securities in a registration
     statement pursuant to this Section 9, the Company shall bear the following
     fees, costs and expenses: all registration, filing and NASD fees, printing
     expenses, fees and disbursements of counsel and accountants for the
     Company, fees and disbursements of counsel for the underwriter or
     underwriters of such securities (if the Company is required to bear such
     fees and disbursements), all internal expenses, the premiums and other
     costs of policies of insurance against liability arising out of the public
     offering, and legal fees and disbursements and other expenses of complying
     with state securities laws of any jurisdictions in which the securities to
     be offered are to be registered or qualified. Fees and disbursements of
     special counsel and accountants for the selling holders, underwriting
     discounts and commissions, and transfer taxes for selling holders and any
     other expenses relating to the sale of securities by the selling holders
     not expressly included above shall be borne by the selling holders.

          (d) The Company shall indemnify each Investor, its officers and
     directors and each person, if any, who controls such Investor within the
     meaning of Section 15 of the Securities Act against all losses, claims,
     damages, and liabilities caused by any untrue statement or alleged untrue
     statement of a material fact contained in the registration statement or
     prospectus (and as amended or supplemented) relating to such registration,
     or caused by any omission or alleged omission to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading in light of the circumstances under which they are made,
     unless such statement or omission was made in reliance upon and in
     conformity with information furnished in writing to the Company expressly
     for use therein by such Investor.

          (e) The Investor shall indemnify the Company, its officers and
     directors and each person, if any, who controls the Company within the
     meaning of Section 15 of the Securities Act against all losses, claims,
     damages, and liabilities caused by any untrue statement or alleged untrue
     statement of a material fact contained in the registration statement or
     prospectus (and as amended or supplemented) relating to such registration,
     or caused by any omission or alleged omission to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading in light of the circumstances under which they are made,
     provided that this paragraph (e) shall apply only to statements or
     --------
     omissions made in reliance upon and in conformity with information
     furnished in writing to the Company expressly for use therein by the
     Investor.

                                      -8-

          (f) The Investor hereby represents that, notwithstanding the exercise
     of the Warrant or the conversion of the Note by such Investor, the Investor
     will not offer for sale, sell, distribute, or otherwise dispose of any
     Warrant Shares or Conversion Shares, or any other Common Stock of the
     Company held by the Investor, for a period of 180 days after the Effective
     Date, except (i) with the consent of the managing underwriter or
     underwriters in such initial public offering, (ii) pursuant to a will or
     the laws of descent and distribution, or (iii) by gift or liquidation of a
     pledge pursuant to which the donee or pledgee agrees in writing to be bound
     by the same restriction on transferability.

          (a)  This Agreement and the rights and obligations of the parties
     hereunder shall not be assignable, in whole or in part, by any party

     Agreement nor any provision hereof may be amended, modified, waived or

     enforcement of such amendment, modification, waiver, or discharge is
     sought, except that the covenant contained in Section 10(a) above may be

          (d)  This Agreement may be executed in two or more counterparts, each
     of which shall be deemed an original, but all of which together shall

     shall be deemed to have accepted the subscription for the Units hereunder,
     only upon execution of this Agreement by the Company.

     IN WITNESS WHEREOF, the undersigned have caused this Agreement to be
executed as of the date set forth above.

                         SUBORDINATED PROMISSORY NOTE
                         ----------------------------

             THIS NOTE IS SUBJECT TO THE RESTRICTIONS ON TRANSFER
                SET FORTH AT THE BOTTOM OF THE LAST PAGE HEREOF

$_____________                                          Minneapolis, Minnesota
                                                              __________, 1996

     FOR VALUE RECEIVED, the undersigned, Fieldworks, Incorporated (the
"Company"), promises to pay to the order of ______________, or its permitted
successors and assigns (the "Holder"), at Holder's address set forth in the
Bridge Agreement (as defined below), or such other place as Holder may designate
in writing from time to time, the principal sum of _______________________
($________), in lawful money of the United States, together with simple interest
from the date hereof on the unpaid principal balance outstanding from time to
time at the rate of ten percent (10%) per year (calculated on the basis of the
actual number of days elapsed and a 360-day year).  All outstanding principal
and accrued interest on this Note shall be due and payable on June 30, 1997,
unless the Company extends such due date in accordance with Section 3 below;
provided, however, that notwithstanding the foregoing, this Note shall be
- --------  -------                                                        
payable in full within thirty (30) days after the effective date (the "Effective
Date") of any registration statement (a "Registration Statement") relating to an
initial public offering of the Company's equity securities registered under the
Securities Act of 1933, as amended (the "Securities Act").

     1.   Bridge Loan Agreement.  This Note has been issued pursuant to and is
          ---------------------                                               
subject to the terms and provisions of the Bridge Loan Agreement (the "Bridge
Agreement"), dated as of ________, 1996, between the Company and Holder, and
this Note and Holder are entitled to all the benefits provided for in the Bridge
Agreement.  The provisions of the Bridge Agreement are incorporated herein by
reference with the same force and effect as if fully set forth herein.

     2.   Prepayment.  This Note may not be prepaid except in the event a
          ----------                                                     
Registration Statement is filed and declared effective, as provided above.

     3.   Extension.  The Company may extend the final maturity of this Note to
          ---------                                                            
December 31, 1997, by written notice delivered to Holder at any time before June
30, 1997.

     4.   Notification of Public Offering.  The Company shall notify Holder of
          -------------------------------                                     
the effectiveness of any Registration Statement within five (5) days after the
Effective Date of such Registration Statement.  Such notice shall be accompanied
by notification that this Note will be paid in full within thirty (30) days
after the Effective Date.
<PAGE>
 
     5.   Conversion of Note.  At any time from the Effective Date to the date
          ------------------                                                  
(30) days after the Effective Date, Holder may elect to convert up to twenty
percent (20%) of the principal amount of this Note ($_______) into shares of the
Company's Common Stock, par value $.001 per share.  Such conversion right shall
be exercised by providing the Company with a written notice in substantially the
form attached hereto specifying the amount of principal that Holder wishes to
convert into shares of Common Stock.  The number of shares of Common Stock
issuable upon such conversion (the "Conversion Shares") shall be determined by
dividing the principal amount to be converted by 80% of the price to public per
share of the Common Stock sold pursuant to the Registration Statement.

     6.   Subordination.  The indebtedness evidenced by this Note is and shall
          -------------                                                       
remain subordinate in right of payment to all Senior Debt to the extent and in
the manner hereinafter set forth.  "Senior Debt" shall mean the principal and
interest on indebtedness of the Company to financial institutions or
institutional lenders for borrowed money (other than the indebtedness evidenced
by this Note and all notes issued to Other Investors (as defined in the Bridge
Agreement)), and for purchase money loans secured by real estate or personal
property used in connection with the business of the Company, whether created,
incurred or assumed before or after the date hereof, except such as by its terms
is expressly not superior in right of payment to this Note, and renewals,
extensions and refundings of any such indebtedness; provided, however, that
                                                    --------  -------      
"Senior Debt" shall in no event include any indebtedness of the Company to
"affiliates" of the Company, as such term is defined under the Securities Act
and the rules and regulations thereunder.  The subordination provisions
contained in this Section 6 are expressly and only for the benefit of third
party senior creditors of the Company and shall in no way limit the rights or
remedies of Holder against the Company, including without limitation the time at
which or the method with which Holder may proceed against the Company for any
default.

     No payment of principal or interest on this Note shall be made if the
Company is in default, or such payment would result in a default, with respect
to the payment of moneys on any Senior Debt.  For purposes of this paragraph,
default with respect to payment of any Senior Debt shall refer to failure of the
Company to pay in full when due the principal of or interest or premium on any
such Senior Debt, or any portion thereof, according to its terms.  Upon any
distribution of assets of the Company, upon dissolution, winding up, liquidation
or reorganization of the Company, whether in bankruptcy, insolvency or
receivership proceedings, or upon an assignment for the benefit of creditors, or
any other marshalling of the assets and liabilities of the Company, or
otherwise, Senior Debt shall first be paid in full, or provision made for such
payment in cash, before any payment is made on account of the principal of and
interest on this Note.  In such events, upon payment in full of all Senior Debt,
Holder shall be subrogated ratably to all rights of such Senior Debtors to
receive payments or distributions of the assets of the Company applicable 

                                      -2-
<PAGE>
 
to such Senior Debt until the principal of and interest on this Note shall be
paid in full.
 
     Notwithstanding the foregoing, payment of principal and interest on this
Note shall not be subordinated to the prior payment of such Senior Debt as to
all amounts which actually are paid by the Company under this Note if the
Company is not in default under any or all of said Senior Debt at the time or
times such payment or payments are made.

     7.   Default.  "Default" means any event which is, or after notice or
          -------                                                         
passage of time, or both, would be, an Event of Default.  An "Event of Default"
occurs if:

          (a)  the Company defaults in the payment of interest on any of the
     Notes (as such term in defined in the Bridge Agreement) when the same
     becomes due and payable, and such default continues for a period of 30
     days;

          (b)  the Company defaults in the payment of the principal of any of
     the Notes when the same becomes due and payable, at maturity or otherwise;
     or

          (c)  the Company defaults in the payment of interest or principal on
     any Senior Debt and such Senior Debt shall, as a result thereof, have been
     accelerated (or comparable event shall have occurred) so that the same
     shall have become due and payable prior to the date on which the same would
     otherwise have become due and payable and such acceleration has been in
     effect without rescission or annulment for a period of 30 days; provided,
     however, that if such default in the payment of interest or principal on
     any Senior Debt shall be remedied or cured by the Company or waived by the
     holders of such Senior Debt, or if such acceleration shall have been
     rescinded or annulled by the holders of such Senior Debt, then, unless this
     Note shall have been accelerated as provided in this Note, the Event of
     Default hereunder by reason thereof shall be deemed likewise to have been
     thereupon remedied, cured or waived without further action upon the part of
     the Holder.

     If an Event of Default occurs and is continuing, the principal of and
interest on all the Notes shall become and be immediately due and payable
without any declaration or other act on the part of Holder or any of the Other
Investors (as such term is defined in the Bridge Agreement).

     Holder may waive an existing Default or Event of Default and its
consequences.  When a Default or Event of Default is waived, it is cured and
ceases.

     8.   Expenses of Enforcement.  The Company agrees to reimburse Holder upon
          -----------------------                                              
demand for all reasonable out-of-pocket expenses, including reasonable

                                      -3-
<PAGE>
 
attorneys' fees, in connection with Holder's enforcement of the Company's
obligations hereunder.

     9.   Investment Intent.  Other than pursuant to registration under federal
          -----------------                                                    
and any applicable state securities laws or an exemption from such registration,
this Note and the Conversion Shares may not be sold, pledged, assigned or
otherwise disposed of (whether voluntarily or involuntarily) by Holder unless
the Company receives from the transferee such representations and agreements as
the Company may determine in its sole discretion to be necessary and appropriate
to permit such transfer to be made pursuant to exemptions from registration
under federal and applicable state securities laws.  Each certificate
representing this Note or any Conversion Shares shall bear appropriate legends
setting forth these restrictions on transfer.  Holder, by acceptance hereof,
agrees to give written notice to the Company at least thirty-five (35) days
before any proposed transfer of this Note or any Conversion Shares describing
briefly the manner of any proposed transfer.  Within thirty (30) days after
receiving such written notice, the Company shall notify Holder as to whether
such transfer may be effected and of the conditions to any such transfer, and
Holder shall abide by such instructions and conditions as to which Holder was
notified by the Company.

     10.  Conversion Shares.
          ----------------- 

          (a)  The Company covenants and agrees that all Conversion Shares that
     may be issued upon the conversion of amounts of principal pursuant to
     Section 5 shall, upon issuance, be duly authorized and issued, fully paid
     and nonassessable shares. The Company further covenants and agrees that
     during the period within which such conversion right may be exercised, the
     Company will at all times have authorized, and reserved for the purpose of
     issue or transfer upon exercise of the conversion right, a sufficient
     number of shares of its Common Stock to provide for the exercise of the
     conversion right.

          (b)  Section 9 of the Bridge Agreement contains certain registration
     rights applicable to the Conversion Shares.

     11.  No Rights As A Shareholder.  The conversion right contained in this
          --------------------------                                         
Note shall not entitle Holder to any voting rights or other rights as a
shareholder of the Company.

     12.  Notices.  All demands and notices to be given hereunder shall be
          -------                                                         
delivered or sent by certified mail, return receipt requested; in the case of
the Company, addressed to its corporate headquarters, 9961 Valley View Road,
Eden Prairie, Minnesota  55344, and in the case of Holder, addressed to the
address written above, in either case, until a new address shall have been
substituted by like notice.

                                      -4-

     13.  Amendment.  Neither this Note nor any term hereof may be changed,
          ---------                                                        
waived, discharged or terminated orally but only by an instrument in writing
signed by the party against which enforcement of the change, waiver, discharge
or termination is sought.

     IN WITNESS WHEREOF, the Company has caused this Note to be executed on its
behalf by its duly authorized officer on the day and year first above written.

                                    WARRANT
                                      FOR
                             SHARES OF COMMON STOCK
                                       OF
                            FIELDWORKS, INCORPORATED


     FOR VALUE RECEIVED, ____________ or its successors or assigns ("Holder"),
is hereby entitled to subscribe for and purchase from Fieldworks, Incorporated,
a Minnesota corporation (the "Company"), up to _________ fully paid and
nonassessable shares (the "Warrant Shares") of the Company's Common Stock, par
value $.001 per share (the "Common Stock"), or such greater or lesser number of
such shares as may be determined by application of the anti-dilution provisions
of this warrant, at an exercise price per share equal to 80% of the price to
public of a share of Common Stock sold in the initial public offering of the
Common Stock; provided, however, that in the event the Company has not completed
              -----------------                                                 
an initial public offering prior to December 31, 1997, then the exercise price
shall be $6.40 per share (the "Warrant Exercise Price").

     This warrant may be exercised by Investor at any time prior to five years
from the date hereof and after the earlier to occur of (i) the date on which
initial public offering of the Company's Common Stock is declared effective or
(ii) December 31, 1997.

     This warrant is subject to the following provisions, terms and conditions:

     1.   (a)  The rights represented by this warrant may be exercised by the
holder hereof, in whole or in part, by written notice of exercise substantially
in the form attached hereto delivered to the Company at least twenty (20) days
prior to the intended date of exercise and by the surrender of this warrant
(properly endorsed if required) at the principal office of the Company and upon
Holder's payment to the Company by cash, certified check or bank draft of the
purchase price for such shares or by exercise of the Conversion Right as
provided in (b) below.  The Warrant 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 Company of the Warrant Exercise Price, unless the
Conversion Right has been exercised.  Certificates for the shares of stock so
purchased, bearing the restrictive legend set forth at the end of this warrant,
shall be delivered to the 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 Warrant Shares, if
any, with respect to which this warrant has not been exercised shall also be
delivered to the holder hereof within such time.  No fractional shares shall be
issued upon the exercise of this warrant.
<PAGE>
 
          (b) In lieu of payment, the rights represented by this warrant may
also be exercised by a written notice of exercise specifying that the Investor
wishes to convert all of this warrant (the "Conversion Right") into that number
of shares of Common Stock as follows: the number of shares of Common Stock equal
to the quotient obtained by dividing (x) the value of the shares subject to the
warrant (determined by subtracting the aggregate warrant exercise price in
effect immediately prior to the exercise of the Conversion Right from the
aggregate fair market value of the shares of Common Stock issuable upon exercise
of this warrant immediately prior to the exercise of the Conversion Right) by
(y) the fair market value of one share of Common Stock immediately prior to the
exercise of the Conversion Right. For purposes of this section 1(b), the fair
market value of a share of Common Stock as of a particular date (the
"Determination Date") shall mean:

              (i)   If the Company's Common Stock is traded on an exchange or is
     quoted on the National Association of Securities Dealers, Inc. Automated
     Quotation ("NASDAQ") National Market System, then the closing or last sale
     price, respectively, reported for the business day immediately preceding
     the Determination Date.

               (ii) If the Company's Common Stock is not traded on an exchange
     or on the NASDAQ National Market System but is quoted on NASDAQ, then the
     mean of the closing bid and asked prices reported for the business day
     immediately preceding the Determination Date.

     2.   The Company covenants and agrees that all Warrant 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.
The Company further covenants and agrees that during the period within which the
rights represented by this warrant may be exercised, the Company will 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.

     3.   The Warrant Exercise Price and the number of Warrant Shares shall be
subject to adjustment from time to time as provided in this Section 3.

          (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 share.

                                      -2-
<PAGE>
 
          (b) If any 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 shares, then, as a condition of such reorganization,
reclassification, consolidation, merger or sale, the holder of this warrant
shall have the right to purchase and receive upon the basis and upon the terms
and conditions specified in this warrant and in lieu of the shares of the Common
Stock of the Company immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby, such shares of stock, other
securities or assets as would have been issued or delivered to the holder of
this warrant if it had exercised this warrant and had received such shares of
Common Stock prior to such 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 the registered holder of this warrant at the last address of such
holder appearing on the books of the Company, the obligation to deliver to such
holder such shares of stock, securities or assets as, in accordance with the
foregoing provisions, such holder may be entitled to purchase.

          (c) If the Company takes any other action, or if any other event
occurs, which does not come within the scope of the provisions of Section 3(a)
or (b), but which should result in an adjustment in the Warrant Exercise Price
and/or the number of shares subject to this warrant in order to fairly protect
the purchase rights of the holder of this warrant, an appropriate adjustment in
such purchase rights shall be made by the Company.

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

          (e) Upon any adjustment of the Warrant Exercise Price, the Company
shall give written notice thereof, by first class mail, postage prepaid,
addressed to the registered holder of this warrant at the address of such holder
as shown on the books of the Company, which notice shall state 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 

                                      -3-
<PAGE>
 
forth in reasonable detail the method of calculation and the facts upon which
such calculation is based.

     4.   This warrant shall not entitle the holder hereof to any voting rights
or other rights as a shareholder of the Company.

     5.   The holder of this warrant, by acceptance hereof, agrees to give
written notice to the Company before transferring this warrant or transferring
any shares of the Company's Common Stock issuable or issued upon the exercise of
this warrant of the holder's intention to do so, describing briefly the manner
of any proposed transfer of this warrant or such holder's intention as to the
shares of Common Stock issuable upon the exercise hereof or the intended
disposition to be made of shares of Common Stock upon such exercise.  Promptly
upon receiving such written notice, the Company shall present copies thereof to
counsel for the Company.  If, in the opinion of such counsel, the proposed
transfer of this warrant or disposition of shares may be effected without
registration or qualification (under any federal or state law) of this warrant
or the shares of Common Stock issuable or issued upon the exercise hereof, the
Company, as promptly as practicable, shall notify such holder of such opinion,
whereupon such holder shall be entitled to transfer this warrant, or to exercise
this warrant in accordance with its terms and dispose of the shares received
upon such exercise or to dispose of shares of Common Stock received upon the
previous exercise of this warrant, all in accordance with the terms of the
notice delivered by such holder to the Company, provided that an appropriate
legend in substantially the form set forth at the end of this warrant respecting
the foregoing restrictions on transfer and disposition may be endorsed on this
warrant or the certificates for such shares.

     6.   Subject to the provisions of Section 5, 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 he/it 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

due from Tenant. In the event the lease term shall begin or expire at any time
during the calendar year, the Tenant shall be responsible for his pro rata share

calendar year thereafter commencing during the term of this Lease or any renewal
or extension thereof, Landlord may estimate for each calendar (i) the total
amount of Real Estate Taxes; (ii) the total amount of Operating Expenses; (iii)
Tenant's share of Real Estate Taxes for such calendar year; (iv) Tenant's share
of Operating Expenses for such calendar year; and (v) the computation of the
annual and monthly rental payable during such calendar year as a result of
increases or decreases in Tenant's share of Real Estate Taxes and Operating
Expenses.  Said estimates will be in writing and will be delivered or mailed to
Tenant at the Premises.

     The amount of Tenant's share of Real Estate Taxes, and Operating Expenses
for each calendar year, so estimated, shall be payable as Additional Rent, in
equal monthly installments, in advance, on the first day of each month during
such calendar year. In the event that such estimate is delivered to Tenant
before the first day of January of such calendar year, said amount, so
estimated, shall be payable as additional rent in equal monthly installments, in
advance, on the first day of each month during such calendar year. In the event
that such estimate is delivered to Tenant after the first day of January of such
calendar year, said amount, so estimated, shall be payable as additional rent in
equal monthly installments, in advance, on the first day of each month over the
balance of such calendar year, with the number of installments being equal to
the number of full calendar months remaining in such calendar year.

     Upon completion of each calendar year during the term of this Lease or any
renewal or extension thereof, Landlord shall cause its accountants to determine
the actual amount of the Real Estate Taxes and Operating Expenses payable in
such calendar year and Tenant's share thereof and deliver a written
certification of the amounts thereof to Tenant. If Tenant has underpaid its
share of Real Estate Taxes, or Operating Expenses for such calendar year, Tenant
shall pay the balance of its share of same within ten (10) days after the
receipt of such statement. If Tenant has overpaid its share of Real Estate Taxes
or Operating Expenses for such calendar year, Landlord shall either (i) refund
such excess or (ii) credit such excess against the most current monthly
installment or installments due Landlord for its estimate of Tenant's share of
Real Estate Taxes and Operating Expenses for the next following calendar year. A
prorata adjustment shall be made for a fractional calendar year occurring during
the term of this Lease or any renewal or extension thereof based upon the number
of days of the term of the Lease during said calendar year as compared to three
hundred sixty-five (365) days and all additional sums payable by Tenant or
credits due Tenant as a result of the provisions of this Article 3 shall be
adjusted accordingly. Tenant shall have the right to inspect Landlord's records
at management office during normal business hours with prior notice.

- -------------- -----------  
when deposit is to be held by Landlord, without liability for interest, as a
security and damage deposit for the faithful performance by Tenant during the
term hereof or any extension hereof.  Prior to the time when Tenant shall be
entitled to the return of this security deposit, Landlord may commingle such

purpose as Landlord may determine.  In the event of the failure of Tenant to
keep and perform any of the terms, covenants, and conditions of this Lease to be
kept and performed by Tenant during the term hereof or any extension hereof,
then Landlord, either with or without terminating this Lease, may (but shall not
be required to ) apply such portion of said deposit as may be necessary to
compensate or repay Landlord for all losses or damages sustained or to be
sustained by Landlord due to such breach on the part of the Tenant, including,
but not limited to overdue and unpaid rent, any other sum payable by Tenant to
landlord pursuant to the provisions of this Lease, damages or deficiencies in
the reletting of Demised Premises, and reasonable attorney's fees incurred by
Landlord.  Should the entire deposit or any portion thereof, be appropriated and
applied by Landlord, in accordance with the provisions of this paragraph.
Tenant, upon written demand by landlord, shall remit forthwith to Landlord a
sufficient amount of cash to restore said security deposit to the original sum
deposited, and Tenant's failure to do so within five (5) days after receipt of
such demand shall constitute a breach of this Lease.  Said security deposit
shall be returned to Tenant, less any depletion thereof as the result of the
provisions of this paragraph, at the end of the term of this Lease or any
renewal thereof, or upon the earlier termination of this Lease.  Tenant shall
have no right to anticipate return of said deposit by withholding any amount
required to be paid pursuant to the provision of this Lease or  otherwise.

     In the event Landlord shall sell the Premises, or shall otherwise convey or
dispose of its interest in this Lease, Landlord may assign said security deposit
or any balance thereof to Landlord's assignees, whereupon landlord shall be
released from all  liability for the return or repayment of such security
deposit and Tenant shall look solely to the said assignees for the return and
repayment of said security deposit.  Said security deposit shall not be assigned
or encumbered by Tenant without such consent of Landlord, and any assignment or
encumbrance without such consent shall not bind Landlord.  In the event of any
rightful and permitted assignment or this Lease by Tenant, said security deposit
shall be deemed to be held by landlord as a deposit made by the assignee, and
Landlord shall have no further liability with respect to the return of said
security deposit to the Tenant.

Landlord shall not in any event be liable for inconvenience, annoyance,
disturbance, loss of business, or other damage of the Tenant by reason of making
repairs or the performance or any work in the Demised Premises, or on account of
bringing materials, supplies, and equipment into or through the Demised Premises
during the course thereof and the obligations of the Tenant under this Lease
shall not thereby be affected in any manner whatsoever.

Landlord reserves the right to enter upon the Demised Premises at any time in
the event of an emergency and at reasonable hours to exhibit the Demised
Premises to prospective purchasers or others; and to exhibit the Demised
Premises during the last sixty (60) days of the term of this Lease, all without
hindrance or molestation by Tenant.

EMINENT DOMAIN:

     13,  In the event of any eminent domain or condemnation proceeding or
private sale in lieu thereof in respect to the  Premises during the term
thereof, the following provisions shall apply:

               a.   If the whole of the Premises shall be acquired or condemned
by eminent domain for any public or quasipublic use or purpose, then the term of
this Lease shall cease and terminate as of the date possession shall be taken in
such proceeding and all rentals shall be paid up to that date.

               b.   If any part constituting less than the whole of the Premises
shall be acquired or condemned as aforesaid, and in the event that such partial
taking or condemnation shall materially affect the Demised Premises so as to
render the Demised Premises unsuitable for the business of the Tenant, in the
reasonable opinion of Landlord, then the term of this Lease shall cease and
terminate as of the date possession shall be taken by the condemning authority
and rent shall be paid to the date of such termination.

     In the event of a partial taking or condemnation of the Premises which
shall not materially affect the Demised Premises so as to render the Demised
Premises unsuitable for the business of the Tenant, in the reasonable opinion of
the Landlord, this Lease shall continue in full force and effect but with a
proportionate abatement of the Base Rent and Additional Rent based on the
portion, if any, of the Demised Premises taken.  Landlord reserves the right, at
its option, to restore the Building and the Demised Premises to substantially
the same  condition as they were prior to such condemnation.  In such event,
Landlord shall give written notice to Tenant, within thirty (30) days following
the date possession shall be taken by the condemning authority, of Landlord's
intention to restore.  Upon Landlord's notice of election to restore, Landlord
shall commence restoration and shall restore the Building and the Demised
Premises with reasonable promptness, subject to delays beyond the Landlord's
control and delays in the making of condemnation or sale proceeds adjustments by
landlord; and Tenant shall have no right to terminate this Lease except as
herein provided.  Upon completion of such restoration, the rent shall be
adjusted based upon the portion, if any, of the Demised Premises restored.

               c.   In the event of any condemnation or taking as aforesaid,
whether whole or partial, the Tenant shall not be entitled to any part of the
award paid for such condemnation and Landlord is to receive the full amount of
such award, the Tenant hereby expressly waiving any right to claim to any part
thereof.

               d.   Although all damages in the event of any condemnation shall
belong to the Landlord whether such damages are awarded as compensation for
diminution in value of the leasehold or to the fee of the Demised Premises,
Tenant shall have the right to claim and recover from the condemning authority,
but not from Landlord, such compensation as may be separately awarded or
recoverable by Tenant in Tenant's own right on account of any and all damage to
Tenant's business by reason of the condemnation and for or on account of any
cost or loss to which Tenant might be put in removing Tenant's merchandise,
furniture, fixtures, leasehold improvements, and equipment. However, Tenant
shall have no claim against Landlord or make any claim with the condemning
authority for the loss of its leasehold estate, any unexpired term or loss of
any possible renewal or extension of said Lease or loss of any possible value of
said Lease, any unexpired term, renewal, or extension of said Lease.

DAMAGE OR DESTRUCTION:

     14.  In the event of any damage or destruction to the Premises by fire of
other cause during the term hereof, the following provisions shall apply:

9/92                                  -5-
<PAGE>
 
               a.   If the Building is damaged by fire or any other cause to
such extent that the cost of restoration, as reasonably estimated by Landlord,
will equal or exceed thirty percent (30%) of the replacement value of the
Building (exclusive of foundations) just prior to the occurrence of the damage,
then Landlord may, no later than the sixtieth (60th) day following the damage,
give Tenant written notice of Landlord's election to terminate this Lease.

               b.   If the cost of restoration as estimated by Landlord will
equal or exceed fifty percent (50%) of said replacement value of the Building
and if the Demised Premises are not suitable as a result of said damage for the
purposes for which they are demised hereunder, in the reasonable opinion of
Tenant, then Tenant may, no later than the sixtieth (60th) day following the
damage, give Landlord a written notice of election to terminate this Lease.

               c.   If the cost of restoration as estimated by Landlord shall
amount to less than thirty percent (30%) of said replacement value of the
Building, or if, despite the cost, Landlord does not elect to terminate this
Lease, Landlord shall restore the Building and the Demised Premises with
reasonable promptness, subject to delays beyond the Landlord's control and
delays in the making of insurance adjustments by Landlord; and Tenant shall have
no right to terminate this Lease except as herein provided. Landlord shall not
be responsible for restoring or repairing leasehold improvements of the Tenant.

               d.   In the event of either of the elections to terminate, this
Lease shall be deemed to terminate as of the date of destruction and all rentals
shall be paid up to that date. Tenant shall have no claim against Landlord for
the value of any unexpired term of this Lease.

               e.   In any case where damage to the Building shall materially
affect the Demised Premises so as to render them unsuitable in whole or in part
for the purposes for which they are demised hereunder, then, unless such
destruction was wholly or partially caused by the negligence or breach of the
terms of this Lease by Tenant, its employees, contractors or licensees, a
portion of the rent based upon the amount of the extent to which the Demised
Premises are rendered unsuitable shall be abated until repaired or restored. If
the destruction or damage was wholly or partially caused by negligence or breach
of the terms of this lease by Tenant as aforesaid and if Landlord shall elect to
rebuild, the rent shall not abate and the Tenant shall remain liable for the
same.

CASUALTY INSURANCE:

          15.  a.   Landlord shall at all times during the term of this Lease,
at its expense, maintain a policy or policies of insurance with premiums paid in
advance issued by an insurance company licensed to do business in the State of
Minnesota insuring the Building against loss or damage by fire, explosion, or
other insurable hazards and contingencies for the full replacement value,
provided that Landlord shall not be obligated to insure any furniture,
equipment, machinery, goods, or supplies not covered by this Lease which Tenant
may bring upon the Demised Premises or any additional improvements which Tenant
may construct or install on the Demised Premises.

               b.   Tenant shall not carry any stock of goods or do anything in
or about the Demised Premises which will in any way impair or invalidate the
obligation of the insurer under any policy of insurance required by this Lease.

               c.   Landlord hereby waives and releases all claims, liabilities,
and causes of action against Tenant and its agents, servants, and employees for
loss or damage to, or destruction of, any of the improvements, fixtures,
equipment, supplies, merchandise, and other property, whether that of Tenant or
of others in, upon, or about the Premises resulting from fire, explosion, or the
other perils included in standard extended coverage insurance, whether caused by
the negligence of any of said persons or otherwise. The waiver shall remain in
force whether or not the Tenant's insurer shall consent thereto.

               d.   In the event that the use of the Demised Premises by Tenant
increases the premium rate for insurance carried by landlord on the improvements
of which the Demised Premises are a part, Tenant shall pay Landlord, upon
demand, the amount of such premium increase. If Tenant installs any electrical
equipment that overloads the power lines to the building or its wiring, Tenant
shall, at its own expense, make whatever changes are necessary to comply with
the requirements of the insurance underwriter, insurance rating bureau, and
governmental authorities having jurisdiction.

PUBLIC LIABILITY INSURANCE:

     16.  Tenant shall during the term hereof keep in full force and effect at
its expense a policy or policies of public liability insurance with respect to
the Demises Premises and the business of Tenant, on terms and companies approved
in writing by Landlord, in which both Tenant and Landlord shall be covered by
being named as insured parties under reasonable limits of liability not less
than: $1,000,000 combined single limit.  Such policy or policies shall provide
that thirty (30) days written notice must be given to the Landlord prior to
cancellation thereof.  Tenant shall furnish evidence satisfactory to landlord at
the time this Lease is executed that such coverage is in full force and effect.

DEFAULT:

     17.  a.   In the event of any failure of Tenant to pay any rental due
hereunder within five (5) days after written notice, or any failure to perform
any other of the terms, conditions, or covenants of this Lease to be observed or
performed by Tenant for more than 30 days (or as long as is reasonably necessary
if Tenant is pursuing a cure in good faith) after written notice of such failure
shall have been given to Tenant, or if Tenant or an agent of Tenant shall
falsify any report required to be furnished to Landlord pursuant to the terms of
this Lease, or if Tenant or any guarantor of this Lease shall become bankrupt or
involvement, or file any debtor proceedings or any person shall take or have
against Tenant or any guarantor of this Lease in any court pursuant to any
statute either of the United States or of any state a petition in bankruptcy or
insolvency or for reorganization or for the appointment of a receiver or trustee
of all or a portion of Tenant's or any such guarantor's property, or if Tenant
or any such guarantor makes an assignment for the benefit of creditors, or
petitions for or enters into an argument, or if Tenant shall abandon the Demised
Premises or suffer this Lease to be taken under any writ of execution, then in
any such event Tenant shall be in default hereunder, and Landlord, in addition
to other rights or remedies it may have, shall have the immediate right of re-
entry and may remove all persons and property from the Demised Premises and such
property may be removed and stored in a public warehouse or elsewhere at the
cost of, and for the account of Tenant, all without service of notice or resort
to legal process and without being guilty of trespass, or becoming liable for
any loss or damage which may be occasioned thereby.

          b.   Should Landlord elect to re-enter the Demised Premises, as herein
provided, or should it take possession of the Demised Premises pursuant to legal
proceedings or pursuant to any notice provided for by law, it may either
terminate this Lease or it may from time to time, without terminating this
Lease, make such alterations and repairs as may be necessary in order to relet
the Demised Premises, and relet the Demised Premises or any part thereof under
such term or terms (which may be for a term extending beyond the term of this
Lease) and at such rental or rentals and upon such other terms and conditions as
Landlord in its sole discretion may deem advisable.  Upon each such subletting
all rentals received by the Landlord from such reletting shall be applied first
to the payment of any indebtedness other than rent due hereunder from Tenant to
landlord; second, to the payment of any costs and expenses of such reletting,
including brokerage fees and attorney's fees and costs of such alterations and
repairs; third, to the payment of the rent due and upon payment of future rent
as the same may become due and payable hereunder.  If such rentals received from
such reletting during any month are less than that to be paid during that month
by Tenant hereunder, Tenant, upon demand, shall pay any such deficiency to
landlord.  No such re-entry or taking possession of the Demised Premises by
Landlord shall be construed as an election on its part to terminate this Lease
unless a written notice of such intention be given to Tenant or unless the
termination thereof be decreed by a court of competent jurisdiction.
Notwithstanding any such reletting without termination.  Landlord may at any
time after such re-entry and reletting elect to terminate this Lease for any
such breach.  In addition to any other remedies it may have, it may recover from
Tenant all damages it may incur by reason of such breach, including the cost of
recovering the Demised Premises, reasonable attorney's fees, and including the
worth at the time of such termination of the excess, if any of the amount of
rent and charges equivalent to rent reserved in this Lease for the remainder of
the stated term over the then reasonable rental value of the Demised Premises
for the remainder of the stated term, all of which amounts shall be immediately
due and payable from Tenant to Landlord.

          c.   Landlord may, at its option, instead of exercising any other
rights or remedies available to it in this Lease or otherwise by law, statute,
or equity, spend such money as is reasonably necessary to cure any default of
Tenant herein and the amount so spent, and costs incurred, including attorney's
fees in curing such default, shall be paid by Tenant, as additional rent, upon
demand.

          d.   In the event suit shall be brought for recovery of possession of
the Demised Premises, for the recovery of rent or any other amount due under the
provisions of this Lease, or because of the breach of any other covenant herein
contained on the part of Tenant to be kept or performed, and a breach shall be
established, Tenant shall pay to Landlord all expenses incurred therefor,
including a reasonable attorney's fee, together with interest on all such
expenses at the  rate of twelve percent (12%) per annum from the date of such
                         -------        -----

granted by or under any present or future laws in the event of Tenant being
evicted or dispossessed for any cause, or in the event of Landlord obtaining
possession of the Demised Premises, by reason of the violation of the Tenant of
any of the covenants or conditions of this Lease, or otherwise. Tenant also
waives any demand for possession of the Demised Premises, and any demand for
payment of rent and any notice of intent to re-enter the Demised Premises, or of
intent to terminate this Lease, other than the notices above provided in this
Article, and waives any and every other notice or demand prescribed by any
applicable statutes or laws.

          f.   No remedy herein or elsewhere in this Lease or otherwise by law,
statute, or equity, conferred upon or reserved to Landlord or Tenant shall be
exclusive of any other remedy, but shall be cumulative, and may be exercised
from time to time and as often as the occasion may arise.

the event of execution by Landlord after the date of this Lease of any such
mortgage, renewal, replacement, or extension, Tenant agrees to execute  a
subordination agreement with the holder thereof which agreement shall provide

such consent of Landlord by a written request, setting forth such information as

right, at its election, then or at any time thereafter which such Event of
Default shall continue, either:

          (1)  To give Tenant written notice that this Lease will terminate on a
date to be specified in such notice, which date shall not be less than five days
after such notice, and on the date specified in such notice. Tenant's right to

being deemed guilty of any manner of trespass and without prejudice to any
remedies to collect rent due from Tenant.

     (c)  If Landlord elects to reenter under subparagraph (b) above, Landlord
may terminate this Lease, or, from time to time, without terminating this Lease,
may relet the Premises, or any part thereof, as agent for Tenant for such terms
and at such rentals and upon such other terms and conditions as Landlord may
deem advisable, with the right to make alterations and repairs to the premises.

jurisdiction.

     (d)  If Landlord terminates this Lease pursuant to Subparagraph (b) above,

the difference between items (i) and (ii) above with respect to each month

prejudice Landlord's right to enforce the collection of any difference for any
subsequent month. In addition to the foregoing, Tenant shall pay to the Landlord
reasonable attorney's fees

                                       5

rental then obtainable giving such concessions of rent and making such special
repairs, alterations, decorations and paintings for any new tenant as Landlord
in its sole and absolute discretion, may deem advisable. Tenant's liability as
aforesaid shall survive the institution of summary proceedings and the issuance
of any warrant thereunder. Landlord shall be under no obligation to relet the
Premises, but agrees to use its best efforts to do so.

10:  BANKRUPTCY TERMINATION PROVISIONS

     (c)  Landlord reserves the right to stop the service of heating, air-
conditioning, ventilating, elevator, plumbing, electricity or other mechanical
systems or facilities in the Premises or the Building, if necessary by reason of
accident or emergency, or for repairs, alterations, replacements, additions or
improvements which, in the reasonable judgment of Landlord, are desirable or
necessary, until said repairs or alterations, replacements, additions or
improvements are completed. Landlord shall provide a rent abatement in the event
services are halted for a prolonged period of time.

13.  SUBLETTING AND ASSIGNMENT
     -------------------------

     (a)  Tenant shall not mortgage, pledge, encumber, sell or assign this Lease
in whole or in part or sublease or sublet the whole or any part of the Premises,
nor permit the Premises to be used by others without the prior written consent
of Landlord, which consent shall not be unreasonably withheld. Any attempted
transfer, assignment, subletting mortgaging or encumbering of this Lease in
violation of the provisions of this section shall be void and confer no rights
upon any third person. No permitted assignment or subletting shall relieve
Tenant of any of its obligations under this Lease.

     (b)  If Tenant's interest in this Lease is assigned, whether or not in
violation of this provisions of this section, Landlord may collect rent from the
assignee. If the Premises or any part thereof are sublet to, or occupied by, or
used by, any person other than Tenant, whether or

                                       7
<PAGE>
 
not in violation of this section, Landlord, after default by Tenant under this
Lease, may collect rent from the subtenant, user or occupant. in either case,
landlord shall apply the amount collected to the rents reserved in this Lease,
but neither any such assignment, subletting, occupancy or use, whether with or
without Landlord's prior consent, nor any such collection or application, shall
be deemed a waiver of any term, covenant or condition of this Lease or the
acceptance by Landlord of such assignee, subtenant, occupant or user as tenant.
The consent by Landlord to any assignment or subletting shall not relieve Tenant
from its obligation to obtain the express prior consent of Landlord to any
further assignment or subletting. Neither an assignment of Tenant's interest in
this Lease nor a subletting occupancy or use of the Premises or any part thereof
by any person other than Tenant, nor the collection of rent by landlord from any
person other than Tenant as provided in this subsection nor the application of
any such rent as provided in this subsection shall, in any circumstances,
relieve Tenant from its obligation fully to observe and perform the terms,
covenants and conditions of this Lease on Tenant's part to be observed and
performed.

     
14.  LIABILITY INSURANCE
     -------------------

     (a)  Tenant, at Tenant's sold cost and expense, shall obtain and maintain
in effect at all times during the Term, a policy of comprehensive general public
liability insurance with broad form property damage endorsement, naming Landlord
and (at Landlord's request) any Mortgagee of the Building and any management
agent as additional named insured(s), protecting Landlord, Tenant and any such
Mortgagee and management agent against any liability for bodily injury, death or
property damage occurring upon, in, or about any part of the Building or the
land on which it is built, the Leased Premises or any appurtenances thereto.
Such policies shall afford protection to the limit of not less than $500,000
with respect to bodily injury of death to any one person, to the limit of not
less than $1,000,000 with respect to bodily injury or death to any number of
persons in any one accident, and to the limit of not less than $100,000 with
respect to damage to the property of any one owner from one occurrence.

     (b)  Any insurance policies required to be obtained by Tenant under this
section: (i) shall be issued by an insurance company of recognized
responsibility licensed to do business in the jurisdiction in which the Building
is located; (ii) shall be written as primary policy coverage and not
contributing with or in excess of any coverage which Landlord may carry. Neither
the issuance of any insurance policy required under this Lease, nor the minimum
limits specified herein with respect to Tenant's insurance coverage, shall be
deemed to limit or restrict in any way Tenant's liability arising under or out
of this Lease. With respect to any insurance policy required to be obtained by
Tenant under this section, on or before the Lease Commencement Date, and at
least thirty (30) days before the expiration of the expiring policy or
certificate previously furnished, Tenant shall deliver to Landlord a certificate
of insurance therefor, together with evidence of payment of all applicable
premiums. Any insurance policy required to be carried hereunder by or on behalf
of Tenant shall provide (and any certificate evidencing the

                                       8
<PAGE>
 
existence of each such insurance policy shall certify) that such insurance
policy shall not be canceled unless Landlord shall have received 20 days' prior
notice of cancellation.

     (c)  Except for the willful or negligent acts or omissions of Landlord or
its agents or employees, Tenant hereby agrees to indemnify and hold harmless
Landlord from and against any and all claims, losses, actions, damages,
liabilities and expenses (including attorney's fees) that (i) arise from or are
in connection with Tenant's possession, use, occupancy, management, repair,
maintenance or control of the Premises, or any portion thereof, or (ii) arise
from or are in connection with any willful or negligent acts or omissions of
Tenant or Tenant's agents, employees, invites or subtenants, or (iii) result
from any default, breach, violations or nonperformance of this lease or any
provision therein by Tenant, or (iv) arise from injury or death to persons or
damage to property sustained on or about the Premises. Tenant shall at its own
cost and expense, defend any and all actions, suits and proceedings which may be
brought against Landlord with respect to the foregoing, or in which Landlord may
be impleaded. Tenant shall pay, satisfy and discharge any and all money
judgments which may be recovered against Landlord in connection with the
foregoing.

15.  FIRE INSURANCE
     --------------

     (a)  Landlord shall, through the Term, at its expense, keep the Building
insured against all loss or damage by fire with extended coverage in such amount
as any first Mortgagee of the Building may from time to time require. Tenant
shall, throughout the Term, at its expense, keep Tenant's alterations to the
Premises and Tenant's personal property insured against all loss or damage by
fire with extended coverage in an amount sufficient to prevent Tenant from
becoming a co-insurer.

          Tenant's policies of insurance shall contain an appropriate clause or
endorsement under which the insurer agrees that such policy shall not be
cancelled without at least 15 days' notice to Landlord.

     (b)  Landlord and Tenant will (i) if requested, advise the other as to the
provisions of fire and extended coverage insurance policies obtained pursuant to
this section, and (ii) notify the other promptly of any change in the terms of
any such policy which would affect such provisions.

16.  DAMAGE BY FIRE OR OTHER CASUALTY
     --------------------------------

     In the event of loss of, or damage to, the Premises or the Building by fire
or other casualty, the rights and obligations of the parties hereto shall be as
follows:

     (a)  If the Premises or any part thereof shall be damaged by fire or other
casualty, Tenant shall give prompt notice thereof to Landlord, and Landlord,
upon receiving such notice, shall proceed promptly and with reasonable
diligence, subject to unavoidable delays and a reasonable time for adjustment of
insurance losses, to repair, or cause to be repaired, such damage in a manner
designed to minimize interference with Tenant's occupancy (but with no

                                       9
<PAGE>
 
obligation to employ labor at overtime or other premium pay rates). If the
Premises or any part thereof shall be rendered untenantable by reason of such
damage, whether to the Premises or the Building, the Base rent and any
additional charges due hereunder shall proportionately abate for the period from
the date of such damage to the date when such damage has been repaired for the
portion of the Premises rendered untenantable.

     (b)  If as a result of fire or other casualty more than one-half (1/2) of
the Building is rendered untenantable, Landlord within 60 days from the date of
such fire or casualty may terminate this Lease by notice to Tenant, specifying a
date, not less than 20 nor more than 40 days after the giving of such notice, on
which the Term shall expire as fully and completely as if such date were the
date herein originally fixed for the expiration of the Term. If the Premises are
damaged as a result of fire or other casualty and if the damage to the Premises
is so extensive that such damage cannot be substantially repaired within 180
days from the date of the fire or other casualty, either Landlord or Tenant
within 30 days from the date of such fire or other casualty may terminate this
Lease by notice to the other, specifying a date, not less than 20 nor more than
40 days after the giving of such notice, on which the Term shall expire as fully
and completely as if such date were the date originally fixed for the expiration
of the Term. If either Landlord or Tenant terminates this Lease, the Base Rent
and all other charges due hereunder shall be apportioned as of the date of such
fire or other casualty. If neither Landlord or Tenant so elects to terminate
this Lease, then Landlord shall proceed to repair the damage to the Building and
the damage to the Premises, if any shall have occurred, and the Base Rent and
any other charges due hereunder shall meanwhile be apportioned and abated all as
provided in this subsection (a).

     (c)  If the Premises shall be rendered untenantable to the extent of eighty
percent (80%) or more by fire or other casualty during the last six months of
the Term, Landlord or Tenant may terminate this Lease upon notice to the other
party given within 90 days after such fire or other casualty specifying a date,
not less than 20 days nor more than 40 days after the giving of such notice, on
which the Term shall expire as fully and completely as if such date were the
date originally fixed for the expiration of the Term. If either Landlord or
Tenant terminates this Lease pursuant to this subsection, the Base Rent and any
additional charges due hereunder shall be apportioned as of the date of such
fire or casualty.

     (d)  Landlord shall not be required to repair or replace any of Tenant's
alterations or improvements or any other personal property of Tenant and no
damages, compensation or claim shall be payable by Landlord for inconvenience,
loss of business by annoyance arising from any repair or restoration of any
portion of the Premises or of the Building.

     (e)  Notwithstanding any other provisions of this Lease, Landlord shall not
be liable or responsible for, and Tenant hereby releases Landlord and its
Partners, officers, directors, agents and employees from and any person claiming
by, through or under Tenant, by way of subrogation or otherwise, for any injury,
loss or damage to Tenant's property covered by a valid and collectible fire
insurance policy with extended coverage endorsement. Tenant shall require its
insurer(s) to include in all of Tenant's insurance policies which could give
rise to a right of subrogation against Landlord a clause or endorsement whereby
the insurer(s) shall waive any

                                       10
<PAGE>
 
rights of subrogation against Landlord, and Tenant shall pay any additional
premium required therefor.

     (f)  Notwithstanding any other provision of this Lease, Tenant shall not be
liable or responsible for, and Landlord hereby releases Tenant and its partners,
officers, directors, agents and employees from, any and all liability or
responsibility to Landlord or any person claiming by, through or under Landlord,
by way of subrogation or otherwise, for any injury, loss or damage to Landlord's
property covered by a valid and collectible fire insurance policy with extended
coverage endorsement. Landlord shall require its insurer(s) to include in all of
Landlord's insurance policies which could give rise to a right of subrogation
against Tenant a clause or endorsement whereby the insurer(s) shall waive any
rights of subrogation against Tenant, and Landlord shall pay any additional
premium required therefor.

     (g)  The proceeds payable under all fire and other hazard insurance
policies maintained by Landlord on the building shall belong to and be the
property of the Landlord, and Tenant shall not have any interest in such
proceeds. Tenant agrees to look to its own fire and hazard insurance policies in
the event of damage to Tenant's alterations or its personal property.

17.  CONDEMNATION
     ------------

     (a)  In the event of a taking under the power of eminent domain or
condemnation ("Taking") of the whole of the Premises, this Lease shall terminate
as of the date of such Taking. If only a part of the Premises shall be so taken
then, except as otherwise provided in this subsection, this Lease shall continue
in force and effect but, from and after the date of the Taking, the Base Rent
and any additional charges due hereunder shall be equitably reduced on the basis
of the portion of the Premises so taken. If a part of the Building shall be
taken, and if (i) the part of the Building so taken contains more than twenty-
five percent (25%) of the Premises immediate to such Taking, or (ii) in
Landlord's reasonable opinion, it shall be impracticable to continue to operate
the Building, then Landlord, may give to Tenant within 50 days after the date
upon which Landlord shall have received notice of the Taking, a 30 day's notice
of termination of this lease. If a 30 days' notice of termination is given by
landlord, this Lease shall terminate upon the expiration of the 30-day period.
If part of the Building, premises or common areas shall be taken and, in
Tenant's reasonable opinion, it shall be impracticable to continue to operate
the Building, then Tenant may give to Landlord within 50 days after the date
upon which Tenant shall have received notice of the Taking, a 30 day'[s notice
of termination of this lease. If a taking occurs which does not result in the
termination of this Lease, Landlord shall repair, alter and restore the
remaining portions of the Premises to their former condition to the extent the
same may be feasible.

     (b)  Landlord shall have the exclusive right to receive any and all awards
made for damages to the Premises and the building accruing by reason of a Taking
or by reason of anything lawfully done in pursuance of public or other
authority. Tenant hereby releases and assigns to Landlord all of Tenant's rights
to such awards, and covenants to deliver such further assignments and assurances
thereof as Landlord may from time to time request. This provision shall not
prevent Tenant from seeking to recover relocation benefits and such business
damages

                                       11
<PAGE>
 
and/or consequential damages as any be allowed by law which do not constitute a
part of the compensation for the Building and do not diminish the amount of the
aware to which landlord would otherwise be entitled.

18.  DEMOLITION AND RENOVATION
     -------------------------

     (a)  In the event Landlord decides to take action which will result in the
demolition and/or renovation of the Building in which the Premises are located,
then this Lease shall automatically be terminated as of One Hundred Eighty (180)
days after Landlord gives written notice of its intent to demolish and/or
renovate.

     (b)  Upon any termination of this Lease under any of the provisions of this
section, the parties shall be released thereby, without further obligation to
the other, from the date possession of the Premises is surrendered to the
Landlord, except for Tenant's obligations which have theretofore accrued and are
then unpaid.

     (c)  Nothwithstanding any destruction or damage to the Premises or the
Building, including the parking facilities and interior and adjacent landscaped
areas, Tenant shall not be released from any of its obligations under this Lease
except to the extent and upon the conditions expressly stated in this section.

19.  ALTERATIONS AND IMPROVEMENTS
     ----------------------------

     (a)  Tenant shall make no alterations, additions or improvements
("Alterations") to the Premises without first obtaining the Landlord's written
consent, which consent shall not be unreasonably withheld. All alterations or
other fixtures, whether temporary or permanent in character (except only the
movable office furniture and equipment of the Tenant), made in or upon the
Premises, either by Tenant or Landlord, shall be Landlord's property and shall
remain upon the Premises at the termination of the Term by lapse of time or
otherwise, without compensation to Tenant. At the option of Landlord, all or any
part of such Alterations may be required by Landlord to be removed from the
Premises at the expiration of the Term or other termination of this Lease at
Tenant's expense and, at Tenant's expense, the Premises shall be restored to
their original condition existing prior to the installation of the alterations
by Tenant, ordinary wear and tear excepted.

     (b)  Tenant shall pay or cause to be paid all costs for work done by Tenant
or caused to be done by Tenant on the Premises of a character which will or may
result in liens on Landlord's interest therein and Tenant will keep the Premises
free and clear of all mechanic's liens and other liens on account of work done
for Tenant or persons claiming under it. Tenant hereby agrees to indemnify,
defend and save Landlord harmless of and from all liability, loss, damage, costs
or expenses, including reasonable attorneys' fees, incurred on account of any
claims of any nature whatsoever for work performed for, or materials or supplies
furnished to Tenant, including lien claims of laborers, materialmen or others.
Should any such liens be filed or recorded against the Premises with respect to
work done or for materials supplied to or on behalf of Tenant or any action
affecting the title thereto be commenced, Tenant shall cause such

                                       12
<PAGE>
 
liens to be removed of record within five (5) days after notice from Landlord.
If Tenant shall be in default in paying any charge for which a mechanic's lien
or suit thereon has been filed and shall not have caused such lien or suit to be
discharged, Landlord may (but without being required to do so) pay such lien or
claim any costs, and the amount so paid, together with reasonable attorneys'
fees incurred in connection therewith, shall be immediately due from Tenant to
Landlord.

20.  RULES AND REGULATIONS

spaces on the on-site parking area of the building. Access and use thereof shall

however, to the rights of any other tenant of the building to park vehicles in
reserved parking spaces as may be provided in such Tenant's lease.

24.  SUBORDINATION

subject to the lien of any Mortgage or Deed of Trust ("Mortgage") made by
landlord against the Building. This Lease and Tenant's interest hereunder shall

subordinate this and deliver any instrument or other document required by any
such Mortgagee to subordinate this Lease and its interest in the Premises to the
lien of such Mortgage.

     (b)  This Lease and Tenant's interest hereunder shall be subject and
subordinate to each and every ground or underlying lease hereafter made of the
Building or the land on which it is constructed, or both, and to all renewals,
modifications, replacements and extensions thereof. Tenant agrees that, within
10 days after the receipt of written request therefor from landlord, it will,
from time to time, execute, acknowledge and deliver any instrument or other

in the Premises to such ground or underlying lease.

building is constructed, or Landlord's leasehold estate in the building, is at
any time subject to a first Mortgage, and (i) this Lease is assigned to the
First Mortgagee, and (ii) Tenant is given written notice of such assignment,
including the name and address of the assignee, then, in such event, Tenant
shall not terminate this Lease or make any abatement in the Base Rent payable

dispute or litigation between Landlord and Tenant with respect to this Lease or
the Premises, the prevailing party shall be entitled to reasonable attorneys'
fees and costs from the other.

Building or the land on which it is constructed, or both, attorn to and
recognize the transferee or purchaser of Landlord's interest or the lessor under
the terminated ground or underlying lease, as the case may be , as Landlord
under this Lease for the balance then remaining of the Term, and thereafter this
Lease shall continue as a direct lease between such person, as "Landlord" and
"Tenant", except that such lessor, transferee or purchaser shall not be liable
for any act or omission of Landlord prior to such lease termination or prior to
such person's succession to title, nor be bound by any payment of Base Rent or
additional charges due hereunder prior to such lease termination or prior to
such person's succession to title for more than one month in advance. Tenant
hereby

                                       14
<PAGE>
 
waives the provisions of any present or future law or regulations which gives or

or other charges have been paid in advance; (v) that Tenant has no knowledge of

any additional facts reasonably requested by any such Mortgagee, assignee of a
Mortgagee or purchaser.

be released from any of its obligations under this Lease because of the
Landlord's failure to perform, where such failure arises from or through
unavoidable delays beyond Landlord's control. If Landlord is so delayed or
prevented from performing any of its obligations during the Term, the period of
such delay or

                                       15

payable under this Lease shall be abated proportionately according to the floor
area of the leased premises which is usable by Tenant, there shall be not
abatement of rent. Such abatement shall continue for the period commencing with
such damage or destruction and ending with the completion by Landlord of such
work of repair and/or reconstruction as Landlord is obligated to do. If,
however, the leased premises or the building should be damaged or destroyed by
any cause so that Landlord shall decide to demolish or to completely rebuild the
leased premises or the building, Landlord may, within sixty days after such

damage or destruction and Tenant shall immediately quit and surrender the leased
premises to Landlord. Tenant is to provide adequate insurance to cover tenant
improvements and equipment.

even attempt to break, evade, or attempt to evade, any of the covenants or
conditions of this Lease, or should he make any assignment for the benefit of
creditors, or commit any act of bankruptcy, or become insolvent, than all of the
said Tenant's right, title and interest in the within Lease shall forthwith
cease, end and determine, and the said Landlord shall be entitled to the
immediate possessions of the herein leased premises and the said Landlord may
file an action in ejectment in the Court of Common Pleases of Centre County, PA
for said premises as if a summons had been regularly issued out of said Court at
the suit of the said Landlord against the said Tenant and had been duly served
and so returned by the Sheriff, and upon the filing of a suggestion covenants of
such Lease file therein by said Landlord, or any agent of the said Landlord, the

     And it is further agreed that, upon the breach by the Tenant of any
Agreement of covenant herein, the Landlord may, within 10 days written notice
via certified mail to rectify the situation, re-enter and repossess said
premises and re-rent the same or substitute other tenants therein and exercise
general supervision and control over said premises for the balance of said term,
and that no such re-entry or re-letting or exercise of right or control over

a surrender of said premises by the Tenant, but shall be an option granted by
the Landlord and reserved by the Landlord to protect its rights and those of the

Tenant after deducting all proper charges, costs, expenses and damages,
including any property attorney's fees, incurred by the Landlord, shall be

                           FIELDWORKS, INCORPORATED 
                           1994 LONG-TERM INCENTIVE
                                      AND
                               STOCK OPTION PLAN


SECTION 1.  PURPOSE OF PLAN.
- ----------------------------

          This Plan shall be known as the "FIELDWORKS, INCORPORATED 1994 LONG-
TERM INCENTIVE AND STOCK OPTION PLAN" and is hereinafter referred to as the
"Plan". The purpose of the Plan is to aid in maintaining and developing
personnel capable of assuring the future success of Fieldworks, Incorporated, a
Minnesota corporation (the "Company"), to offer such personnel additional
incentives to put forth maximum efforts for the success of the business, and to
afford them an opportunity to acquire a proprietary interest in the Company
through stock options and other long-term incentive awards as provided herein.
Options granted under this Plan may be either incentive stock options
("Incentive Stock Options") within the meaning of Section 422 of the Internal
Revenue Code of 1986 (the "Code"), or options that do not qualify as Incentive
Stock Options. Awards granted under this Plan shall be SARs, restricted stock or
performance awards as hereinafter described.

SECTION 2.  STOCK SUBJECT TO PLAN.
- ----------------------------------

          Subject to the provisions of Section 16 hereof, the stock to be
subject to options or other awards under the Plan shall be the Company's
authorized common shares, par value $0.01 per share (the "Common Shares"). Such
Common Shares may be either authorized but unissued shares, or issued shares
which have been reacquired by the Company. Subject to adjustment as provided in
Section 16 hereof, the maximum number of shares on which options may be
exercised or other awards issued under this Plan shall be 720,000 shares. If an
option or award under the Plan expires, or for any reason is terminated or
unexercised with respect to any shares, such shares shall again be available for
options or awards thereafter granted during the term of the Plan.

SECTION 3.  ADMINISTRATION OF PLAN.
- -----------------------------------

          (a)  The Plan shall be administered by the Board of Directors of the
Company or a committee thereof. The members of any such committee shall be
appointed by and serve at the pleasure of the Board of Directors. (The group
administering the Plan shall hereinafter be referred to as the "Committee".)

          (b)  The Committee shall have plenary authority in its discretion, but
subject to the express provisions of the Plan: (i) to determine the purchase
price of the Common Stock covered by each option or award, (ii) to determine the
employees to whom and the time or times at which such options and awards shall
be granted and the number of shares to be subject to each, 

                                       1
<PAGE>
 
(iii) to determine the form of payment to be made upon the exercise of an SAR or
in connection with performance awards, either cash, Common Shares of the Company
or a combination thereof, (iv) to determine the terms of exercise of each option
and award, (v) to accelerate the time at which all or any part of an option or
award may be exercised, (vi) to amend or modify the terms of any option or award
with the consent of the optionee, (vii) to interpret the Plan, (viii) to
prescribe, amend and rescind rules and regulations relating to the Plan, (ix) to
determine the terms and provisions of each option and award agreement under the
Plan (which agreements need not be identical), including the designation of
those options intended to be Incentive Stock Options, and (x) to make all other
determinations necessary or advisable for the administration of the Plan,
subject to the exclusive authority of the Board of Directors under Section 17
herein to amend or terminate the Plan. The Committee's determinations on the
foregoing matters, unless otherwise disapproved by the Board of Directors of the
Company, shall be final and conclusive.

          (c)  The Committee shall select one of its members as its Chair and
shall hold its meetings at such times and places as it may determine. A majority
of its members shall constitute a quorum. All determinations of the Committee
shall be made by not less than a majority of its members. Any decision or
determination reduced to writing and signed by all of the members of the
Committee shall be fully effective as if it had been made by a majority vote at
a meeting duly called and held. The grant of an option or award shall be
effective only if a written agreement shall have been duly executed and
delivered by and on behalf of the Company following such grant. The Committee
may appoint a Secretary and may make such rules and regulations for the conduct
of its business as it shall deem advisable.

SECTION 4.  ELIGIBILITY AND GRANT.
- ----------------------------------

          (a)  Eligibility.  Incentive Stock Options may only be granted under
               -----------
this Plan to any full or part-time employee (which term as used herein includes,
but is not limited to, officers anddirectors who are also employees) of the
Company and of its present and future subsidiary corporations within the meaning
of Section 424(f) of the Code (herein called "subsidiaries"). Full or part-time
employees, directors who are not employees, consultants or independent
contractors to the Company or one of its subsidiaries or affiliates shall be
eligible to receive options which do not qualify as Incentive Stock Options and
awards. In determining the persons to whom options and awards shall be granted
and the number of shares subject to each, the Committee may take into account
the nature of services rendered by the respective employees or consultants,
their present and potential contributions to the success of the Company and such
other factors as the Committee in its discretion shall deem relevant.

          (b)  Grant of Additional Options.  A person who has been granted an
               ---------------------------
option or award under this Plan may be granted additional options or awards
under the Plan if the Committee shall so determine; provided, however, that to
the extent the aggregate fair market value (determined at the time the Incentive
Stock Option is granted) of the Common Shares with respect to which all
Incentive Stock Options are exercisable for the first time by an employee during
any calendar year (under all plans described in subsection (d) of Section 422 of
the Code of his or her employer corporation and its parent and subsidiary
corporations) exceeds $100,000, 

                                       2
<PAGE>
 
such options shall be treated as options that do not qualify as Incentive Stock
Options. Nothing in the Plan or in any agreement thereunder shall confer on any
employee any right to continue in the employ of the Company or any of its
subsidiaries or affect, in any way, the right of the Company or any of its
subsidiaries to terminate his or her employment at any time.

SECTION 5.  PRICE.
- ------------------

          The option price for all Incentive Stock Options granted under the
Plan shall be determined by the Committee but shall not be less than 100% of the
fair market value of the Common Shares at the date of grant of such option. The
option price for options granted under the Plan that do not qualify as Incentive
Stock Options and, if applicable, the price for all awards shall also be
determined by the Committee. For purposes of the preceding sentence and for all
other valuation purposes under the Plan, the fair market value of the Common
Shares shall be as reasonably determined by the Committee. If on the date of
grant of any option or award hereunder the Common Shares are not traded on an
established securities market, the Committee shall make a good faith attempt to
satisfy the requirements of this Section 5 and in connection therewith shall
take such action as it deems necessary or advisable.

SECTION 6.  TERM.
- -----------------

          Each option and award and all rights and obligations thereunder shall
expire on the date determined by the Committee and specified in the option or
award agreement. The Committee shall be under no duty to provide terms of like
duration for options or awards granted under the Plan, but the term of an
Incentive Stock Option may not extend more than ten (10) years from the date of
grant of such option and the term of options granted under the Plan which do not
qualify as Incentive Stock Options may not extend more than fifteen (15) years
from the date of granting of such option.

SECTION 7.  EXERCISE OF OPTION OR AWARD.
- ----------------------------------------

          (a)  Exercisability.  The Committee shall have full and complete
               -------------- 
authority to determine whether an option or award will be exercisable in full at
any time or from time to time during the term thereof, or to provide for the
exercise thereof in such installments, upon the occurrence of such events (such
as termination of employment for any r eason) and at such times during the term
of the option as the Committee may determine and specify in the option or award
agreement.

          (b)  No Violation of State or Federal Laws.  The exercise of any 
               ------------------------------------- 
option or award granted hereunder shall only be effective at such time that the
sale of Common Shares pursuant to such exercise will not violate any state or
federal securities or other laws.

          (c)  Method of Exercise.  An optionee or grantee electing to exercise 
               ------------------
an option or award shall give written notice to the Company of such election and
of the number of shares subject to such exercise. The full purchase price of
such shares shall be tendered with such notice

                                       3
<PAGE>
 
of exercise. Payment shall be made to the Company in cash (including bank check,
certified check, personal check, or money order), or, at the discretion of the
Committee and as specified by the Committee, (i) by delivering certificates for
the Company's Common Shares already owned by the optionee or grantee having a
fair market value as of the date of grant equal to the full purchase price of
the shares, or (ii) by delivering the optionee's or grantee's promissory note,
which shall provide for interest at a rate not less than the minimum rate
required to avoid the imputation of income, original issue discount or a below-
market-rate loan pursuant to Sections 483, 1274 or 7872 of the Code or any
successor provisions thereto, or (iii) a combination of cash, the optionee's or
grantee promissory note and such shares. The fair market value of such tendered
shares shall be determined as provided in Section 5 herein. The optionee's or
grantee's promissory note shall be a full recourse liability of the optionee and
may, at the discretion of the Committee, be secured by a pledge of the shares
being purchased. Until such person has been issued the shares subject to such
exercise, he or she shall possess no rights as a shareholder with respect to
such shares.

SECTION 8.  RESTORATION OPTIONS.
- --------------------------------

          The Committee may grant "restoration" options, separately or together
with another option, pursuant to which, subject to the terms and conditions
established by the Committee and any applicable requirements of Rule 16b-3
promulgated under the Exchange Act or any other applicable law, the optionee
would be granted a new option when the payment of the exercise price of the
option to which such "restoration" option relates is made by the delivery of
shares of the Company's Common Shares owned by the optionee, as described in
this Section 8, which new option would be an option to purchase the number of
shares not exceeding the sum of (a) the number of shares of the Company's Common
Shares tendered as payment upon the exercise of the option to which such
"restoration" option relates and (b) the number of shares of the Company's
Common Shares, if any, tendered as payment of the amount to be withheld under
applicable income tax laws in connection with the exercise of the option to
which such "restoration" option relates, as described in Section 12 hereof.
"Restoration" options may be granted with respect to options previously granted
under this Plan or any prior stock option plan of the Company, and may be
granted in connection with any option granted under this Plan at the time of
such grant. The purchase price of the Common Shares under each such new option,
and the other terms and conditions of such option, shall be determined by the
Committee, consistent with the provisions of the Plan.

SECTION 9.  STOCK APPRECIATION RIGHTS.
- --------------------------------------

          (a)  Grant.  At the time of grant of an option or award under the Plan
               -----
(or at any other time), the Committee, in its discretion, may grant a Stock
Appreciation Right ("SAR") evidenced by an agreement in such form as the
Committee shall from time to time approve. Any such SAR may be subject to
restrictions on the exercise thereof as may be set forth in the agreement
representing such SAR, which agreement shall comply with and be subject to the
following terms and conditions and any additional terms and conditions
established by the Committee that are consistent with the terms of the Plan.

                                       4
<PAGE>
 
          (b)  Exercise.  An SAR shall be exercised by the delivery to the 
               -------- 
Company of a written notice which shall state that the holder thereof elects to
exercise his or her SAR as to the number of shares specified in the notice and
which shall further state what portion, if any, of the SAR exercise amount
(hereinafter defined) the holder thereof requests is to be paid in cash and what
portion, if any, is to be paid in Common Shares of the Company. The Committee
promptly shall cause to be paid to such holder the SAR exercise amount either in
cash, in Common Shares of the Company, or any combination of cash and shares as
the Committee may determine. Such determination may be either in accordance with
the request made by the holder of the SAR or in the sole and absolute discretion
of the Committee. The SAR exercise amount is the excess of the fair market value
of one share of the Company's Common Shares on the date of exercise over the per
share exercise price in respect of which the SAR was granted, multiplied by the
number of shares as to which the SAR is exercised. For the purposes hereof, the
fair market value of the Company's shares shall be determined as provided in
Section 5 herein.

SECTION 10. RESTRICTED STOCK AWARDS.
- ------------------------------------

          Awards of Common Shares subject to forfeiture and transfer
restrictions may be granted by the Committee. Any restricted stock award shall
be evidenced by an agreement in such form as the Committee shall from time to
time approve, which agreement shall comply with and be subject to the following
terms and conditions and any additional terms and conditions established by the
Committee that are consistent with the terms of the Plan:

          (a)  Grant of Restricted Stock Awards.  Each restricted stock award 
               --------------------------------- 
made under the Plan shall be for such number of Common Shares as shall be
determined by the Committee and set forth in the agreement containing the terms
of such restricted stock award. Such agreement shall set forth a period of time
during which the grantee must remain in the continuous employment of the Company
in order for the forfeiture and transfer restrictions to lapse. If the Committee
so determines, the restrictions may lapse during such restricted period in
installments with respect to specified portions of the shares covered by the
restricted stock award. The agreement may also, in the discretion of the
Committee, set forth performance or other conditions that will subject the
Common Shares to forfeiture and transfer restrictions. The Committee may, at its
discretion, waive all or any part of the restrictions applicable to any or all
outstanding restricted stock awards.

          (b)  Delivery of Common Shares and Restrictions.  At the time of a
               ------------------------------------------ 
restricted stock award, a certificate representing the number of Common shares
awarded thereunder shall be registered in the name of the grantee. Such
certificate shall be held by the Company or any custodian appointed by the
Company for the account of the grantee subject to the terms and conditions of
the Plan, and shall bear such a legend setting forth the restrictions imposed
thereon as the Committee, in its discretion, may determine. The grantee shall
have all rights of a shareholder with respect to the Common Shares, including
the right to receive dividends and the right to vote such shares, subject to the
following restrictions: (i) the grantee shall not be entitled to delivery of the
stock certificate until the expiration of the restricted period and the
fulfillment 

                                       5
<PAGE>
 
of any other restrictive conditions set forth in the restricted stock agreement
with respect to such Common Shares; (ii) none of the Common Shares may be sold,
assigned, transferred, pledged, hypothecated or otherwise encumbered or disposed
of during such restricted period or until after the fulfillment of any such
other restrictive conditions; and (iii) except as otherwise determined by the
Committee, all of the Common Shares shall be forfeited and all rights of the
grantee to such Common Shares shall terminate, without further obligation on the
part of the Company, unless the grantee remains in the continuous employment of
the Company for the entire restricted period in relation to which such Common
Shares were granted and unless any other restrictive conditions relating to the
restricted stock award are met. Any Common Shares, any other securities of the
Company and any other property (except for cash dividends) distributed with
respect to the Common Shares subject to restricted stock awards shall be subject
to the same restrictions, terms and conditions as such restricted Common Shares.

          (c)  Termination of Restrictions.  At the end of the restricted period
               --------------------------- 
and provided that any other restrictive conditions of the restricted stock award
are met, or at such earlier time as otherwise determined by the Committee, all
restrictions set forth in the agreement relating to the restricted stock award
or in the Plan shall lapse as to the restricted Common Shares subject thereto,
and a stock certificate for the appropriate number of Common Shares, free of the
restrictions and the restricted stock legend, shall be delivered to the grantee
or his or her beneficiary or estate, as the case may be.

SECTION 11. PERFORMANCE AWARDS.
- -------------------------------
     
          The Committee is further authorized to grant performance awards.
Subject to the terms of this Plan and any applicable award agreement, a
performance award granted under the Plan (i) may be denominated or payable in
cash, Common Shares (including, without limitation, restricted stock), other
securities, other awards, or other property and (ii) shall confer on the holder
thereof rights valued as determined by the Committee, in its discretion, and
payable to, or exercisable by, the holder of the Performance awards, in whole or
in part, upon the achievement of such performance goals during such performance
periods as the Committee, in its discretion, shall establish. Subject to the
terms of this Plan and any applicable award agreement, the performance goals to
be achieved during any performance period, the length of any performance period,
the amount of any Performance award granted, and the amount of any payment or
transfer to be made by the grantee and by the Company under any Performance
award shall be determined by the Committee.

SECTION 12. INCOME TAX WITHHOLDING AND TAX BONUSES.
- ---------------------------------------------------

          (a)  Withholding of Taxes.  In order to comply with all applicable
               -------------------- 
federal or state income tax laws or regulations, the Company may take such
action as it deems appropriate to ensure that all applicable federal or state
payroll, withholding, income or other taxes, which are the sole and absolute
responsibility of an optionee or grantee under the Plan, are withheld or
collected from such optionee or grantee. In order to assist an optionee or
grantee in paying all federal and state taxes to be withheld or collected upon
exercise of an option or award which 

                                       6
<PAGE>
 
does not qualify as an Incentive Stock Option hereunder, the Committee, in its
absolute discretion and subject to such additional terms and conditions as it
may adopt, shall permit the optionee or grantee to satisfy such tax obligation
by (i) electing to have the Company withhold a portion of the shares otherwise
to be delivered upon exercise of such option or award with a fair market value,
determined in accordance with Section 5 herein, equal to such taxes or (ii)
delivering to the Company

          Common Shares other than the shares issuable upon exercise of such
option or award with a fair market value, determined in accordance with Section
5, equal to such taxes.

          (b)  Tax Bonus.  The Committee shall have the authority, at the time 
               --------- 
of grant of an option under the Plan or at any time thereafter, to approve tax
bonuses to designated optionees or grantees to be paid upon their exercise of
options or awards granted hereunder. The amount of any such payments shall be
determined by the Committee. The Committee shall have full authority in its
absolute discretion to determine the amount of any such tax bonus and the terms
and conditions affecting the vesting and payment thereafter.

SECTION 13. ADDITIONAL RESTRICTIONS.
- ------------------------------------

          The Committee shall have full and complete authority to determine
whether all or any part of the Common Shares of the Company acquired upon
exercise of any of the options or awards granted under the Plan shall be subject
to restrictions on the transferability thereof or any other restrictions
affecting in any manner the optionee's or grantee's rights with respect thereto,
but any such restriction shall be contained in the agreement relating to such
options or awards.

SECTION 14. TEN PERCENT SHAREHOLDER RULE.
- -----------------------------------------

          Notwithstanding any other provision in the Plan, if at the time an
option is otherwise to be granted pursuant to the Plan the optionee owns
directly or indirectly (within the meaning of Section 424(d) of the Code) Common
Shares of the Company possessing more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company or its parent or
subsidiary corporations, if any (within the meaning of Section 422(b)(6) of the
Code), then any Incentive Stock Option to be granted to such optionee pursuant
to the Plan shall satisfy the requirements of Section 422(c)(5) of the Code, and
the option price shall be not less than 110% of the fair market value of the
Common Shares of the Company determined as described herein, and such option by
its terms shall not be exercisable after the expiration of five (5) years from
the date such option is granted.

SECTION 15. NON-TRANSFERABILITY.
- --------------------------------

          No option or award granted under the Plan shall be transferable by an
optionee or grantee, otherwise than by will or the laws of descent or
distribution. Except as otherwise provided in an option or award agreement,
during the lifetime of an optionee or grantee, the option shall be exercisable
only by such optionee or grantee.

                                       7
<PAGE>
 
SECTION 16. DILUTION OR OTHER ADJUSTMENTS.
- ------------------------------------------

          If there shall be any change in the Common Shares through merger,
consolidation, reorganization, recapitalization, dividend in the form of stock
(of whatever amount), stock split or other change in the corporate structure,
appropriate adjustments in the Plan and outstanding options and awards shall be
made by the Committee. In the event of any such changes, adjustments shall
include, where appropriate, changes in the aggregate number of shares subject to
the Plan, the number of shares and the price per share subject to outstanding
options and awards and the amount payable upon exercise of outstanding awards,
in order to prevent dilution or enlargement of option or award rights.

SECTION 17. AMENDMENT OR DISCONTINUANCE OF PLAN.
- ------------------------------------------------

          The Board of Directors may amend or discontinue the Plan at any time.
Subject to the provisions of Section 16 no amendment of the Plan, however, shall
without shareholder approval: (i) increase the maximum number of shares under
the Plan as provided in Section 2 herein, (ii) decrease the minimum price
provided in Section 5 herein, (iii) extend the maximum term under Section 6, or
(iv) modify the eligibility requirements for participation in the Plan. The
Board of Directors shall not alter or impair any option or award theretofore
granted under the Plan without the consent of the holder of the option.

SECTION 18. TIME OF GRANTING.
- -----------------------------

          Nothing contained in the Plan or in any resolution adopted or to be
adopted by the Board of Directors or by the shareholders of the Company, and no
action taken by the Committee or the Board of Directors (other than the
execution and delivery of an option or award agreement), shall constitute the
granting of an option or award hereunder.

SECTION 19. EFFECTIVE DATE AND TERMINATION OF PLAN.
- ---------------------------------------------------

          (a)  The Plan was approved by the Board of Directors on March 23,
1994, and shall be approved by the shareholders of the Company within twelve
(12) months thereof.

          (b)  Unless the Plan shall have been discontinued as provided in
Section 16 hereof, the Plan shall terminate March 23, 2004. No option or award
may be granted after such termination, but termination of the Plan shall not,
without the consent of the optionee or grantee, alter or impair any rights or
obligations under any option or award theretofore granted.

the right and option (hereinafter called "the option") to purchase all or any
part of an aggregate of _______ common shares, par value $0.01 per share (the
"Common Shares"), at the price of $_____ per share on the terms and conditions
set forth herein. This option is not intended to be an incentive stock option
within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code").

     2. Duration and Exercisability
        ---------------------------
     
          (a)  This option shall in all events terminate five (5) years after
the date of grant subject to the other terms and conditions set forth herein,
this option may be exercised by Employee in cumulative installments as follows:
   
                                         Cumulative percentage       
          On or after each of            of shares as to which       
          the following dates            option is exercisable       
          -------------------            ---------------------       

                 xx/xx/xx                         34%                
                 xx/xx/xx                         33%                
                 xx/xx/xx                         33%                 

          (b)  During the lifetime of Employee, the option shall be exercisable

          (c)  Notwithstanding the installment exercise provision set forth in
paragraph (a) above and subject to the other terms and conditions set forth
herein, this option may be exercised as to 100% of the Common Shares of the
Company for which this option was granted on the date of a "change of control"
as hereinafter defined. A "change of control" shall mean any of the following:
 
               (i)    A sale of all or substantially all of the assets of the
     Company. 
 
               (ii)   The acquisition of more than 80% of the Common Shares of
     the Company (with all classes or series thereof treated as a single class)
     by any person or group of persons, except a Permitted Shareholder as
     hereinafter defined, acting in concert. A "Permitted Shareholder" means a
     holder, as of the date the Plan was adopted by the Company, of Company
     Common Shares.
 
               (iii)  A reorganization of the Company wherein the holders of
     Common Shares of the Company receive stock in another company, a merger of 
     the Company with another company wherein there is an 80 % or greater change
     in the ownership of the Common Shares of the Company as a result of such
     merger, or any other transaction in which the Company (other than as the
     parent corporation) is consolidated for federal income tax purposes with
     another corporation.

               (iv)   In the event that the Common Shares of the Company are
     traded on an established securities market: a public announcement that any
     person has acquired or has the right to acquire beneficial ownership of 51%
     or more of the then outstanding Common Shares of the Company and for this
     purpose the terms "person" and "beneficial ownership" shall have the
     meanings provided in Section 13(d) of the Securities and Exchange Act of
     1934 or related rules promulgated by the Securities and Exchange Commission
     or: the commencement of or public announcement of an intention to make a
     tender offer or exchange offer for 51% or more of the then outstanding
     Common Shares of the Company.

               (v)    The Board of Directors of the Company, in its sole and
     absolute discretion, determines that there has been a sufficient change in
     the share ownership of the Company to constitute a change of effective
     ownership or control of the Company.

Employee understands that to the extent that the aggregate fair market value
(determined at the time the option was granted) of the Common Shares with
respect to which all options, that are incentive stock options within the
meaning of Section 422 of the Code, are exercisable for the first time by
Employee during any calendar year exceed $100,000, in accordance with Section
422(d) of the Code, such options shall be treated as options that do not qualify
as incentive stock options.

     3.   Effect of Termination of Employment
          -----------------------------------  

          (a)  In the event that Employee shall cease to be employed by the
Company or its subsidiaries, if any, for any reason other than Employee's 
serious misconduct or Employee's death or disability (as such term is defined in
Section 3(c) hereof), Employee shall have the right to exercise the option at
any time within one (1) month after such termination of employment to the extent

exercisable after the expiration of the term of the option.

          (b)  In the event that Employee shall cease to be employed by the
Company or its subsidiaries, if any, by reason of Employee's serious misconduct
during the course of employment, including but not limited to wrongful
appropriation of the Company's funds, or in the event that Employee violates the
covenants set forth in Section 5 hereof, the option shall be terminated as of
the date of the misconduct.

          (c)  If Employee shall die while in the employ of the Company or a
subsidiary, if any, or within one (1) month after termination of employment for
any reason other than serious misconduct or if employment is terminated because
Employee has become disabled (within the meaning of Code Section 22(e)(3)) while
in the employ of the Company or a subsidiary, if any, and Employee shall not
have fully exercised the option, such option may be exercised at any time within
twelve (12) months after Employee's death or date of termination of employment
for disability by Employee, personal representatives or administrators, or
guardians of Employee, as applicable, or by any person or persons to whom the
option is transferred by will or the applicable laws of descent and
distribution, to the extent of the full number of shares Employee was entitled
to purchase under the option on the date of death, termination of employment, if
earlier, or date of termination for such disability and subject to the condition
that no option shall be exercisable after the expiration of the term of the
option.

Employee' full recourse liability promissory note

     6.   Company's Option to Repurchase Common Shares
          --------------------------------------------

          (a)  Upon the occurrence of any one or more of the Option Events, as
hereinafter defined, the Company shall have the irrevocable right and option
(the oCall Optiono) to purchase from Employee or Employee's heirs, successors,
personal representatives or assigns, and Employee on behalf of his or her heirs,
successors, personal representatives or assigns, agrees to sell to the Company
upon the exercise of the Call Option all or any part of the Common Shares
acquired by Employee pursuant to this option. (The Company's Call Option, and
any reference to Common Shares acquired by Employee pursuant to this option,
shall be deemed to include all other shares of any class or series of the
Company's capital stock acquired by Employee on account of or with respect to
Common Shares acquired pursuant to this option, whether the acquisition of such
shares is by stock dividend, stock split, recapitalization or any other similar
means.) The Option Events shall be:

               (i)    The express desire of Employee to sell, assign, pledge,
     transfer, give or otherwise dispose of or encumber any Common Shares 
     acquired by Employee pursuant to this option to a bona fide third party or 
     any attempt by Employee to transfer any such Common Shares except in strict
     compliance with the terms and conditions of this Agreement.
 
               (ii)   The employment by a court of competent jurisdiction or
     otherwise of a receiver, trustee or assignee of Employee or Employee's
     property.
 
               (iii)  The expiration of thirty (30) days immediately following
     the date upon which a money judgment entered in a court of record against
     Employee becomes final, provided such judgment remains unsatisfied.
 
               (iv)   Voluntary application of Employee for relief any act of
     Congress or any of the laws of the several states now or hereafter enacted
     providing for the relief of debtors. 

               (v)    Institution of a levy, garnishment or attachment involving
     such Common Shares, unless released or discharged within a period of thirty
     (30) days. 
     

                                       13
<PAGE>
 
               (vi)  Employee's termination of employment with the Company, 
whether voluntary or involuntary with or without cause, including without 
limitation termination as a result of death or disability.

          (b)  Upon the occurrence of any one or more of the Option Events, 
Employee (or a legal representative thereof) shall deliver a written notice 
thereof to the Company, which notice shall specify the Option Event, the person 
to whom the shares are to be sold, transferred, exchanged or disposed of, if 
applicable, the purchase price or other consideration to be received by Employee
for such shares, if any, and the terms upon which such purchase price or other 
consideration is to be paid, if applicable. The Company may then exercise its 
Call Option with respect to all or any part of such Common Shares by delivering 
a written acceptance to Employee (or a legal representative thereof) within 
thirty (30) days after receipt of the foregoing written notice from Employee. If
the Company elects not to exercise the Call Option, Employee (or a legal 
representative thereof) shall be able to transfer or encumber such shares on the
terms specified in the written notice to the Company, but only if such 
transaction is consummated within ninety (90) days after such notice to the 
Company.

          (c)  The purchase price for the Common Shares that are repurchased by 
the Company pursuant to the exercise of its Call Option shall be either the 
amount to be paid therefor by a bona fide third party purchaser or the fair 
market value thereof, whichever is greater. The fair market value of the Common 
Shares shall be determined by the Company's Board of Directors; provided, 
however, that if upon the occurrence of an Option Event the Company's Common 
Shares are then traded on an established securities market, the fair market 
thereof shall be determined by reference to such trading price, as determined by
the Company in its sold and absolute discretion.

          (d)  The Company shall make payment of the purchase price for any 
Common Shares reacquired by it pursuant to its exercise of the Call Option by 
delivering to Employee or Employee's heirs, successors, assigns or personal 
representatives, as the case may be, either (i) the Company's check in the 
amount of the purchase price or (ii) the Company's promissory note in the amount
of the purchase price, which promissory note shall provide for a term not to 
exceed five (5) years and interest on the unpaid balance thereof at a rate which
is not less than the minimum rate required to avoid the imputation of income, 
original issue discount or a below market rate loan pursuant to Sections
483,1274 and 7872 of the Code or any successor provisions thereto, as determined
by the Company, or (iii) a combination of cash and the Company's promissory
note, with the foregoing terms, the total of which is equal to such purchase
price. Upon receipt of such payment from the Company, Employee or his or her
heirs, successors, assigns or personal representatives, as the case may be,
shall deliver to the Company for Cancellation the stock certificate or
certificates evidencing the

                                      14
<PAGE>
 
     Common Shares being repurchased by the Company pursuant to the exercise of
its Call Option, which certificate or certificates shall be duly endorsed for
cancellation by the Company.

          (e)  Employee shall not voluntarily or involuntarily sell, exchange, 
transfer, pledge or otherwise dispose of any of the Common Shares acquired 
pursuant to the exercise of this option unless Employee shall first offer to 
sell such Common Shares to the Company's Call Option as described above. The 
following legend shall be affixed to the certificates evidencing the Common 
Shares acquired pursuant to the exercise of this option.

          The shares evidence by this certificate are subject to restrictions on
transferability and the repurchase options contained in an Incentive Stock 
Option Agreement dated___________, 19__ between ___________ and FieldWorks, 
Incorporated, a Minnesota corporation, a copy of which is available for review 
at the principal offices of FieldWorks, Incorporated.

     7.   Miscellaneous
          -------------

          (a)  This option is issued pursuant to the Company's 1994 Long Term 
and Incentive Stock Option Plan and is subject to its terms. The terms of the 
Plan are available for inspection during business hours at the principal offices
of the Company.

          (b)  This Agreement shall not confer on Employee any right with 
respect to continuance of employment by the Company or any of its subsidiaries,
nor will it interfere in any way with the right of the Company to terminate such
employment at any time. Employee shall have none of the rights of a shareholder 
with respect to shares subject to this option until such shares shall have been
issued to Employee upon exercise of this option.

          (c)  The exercise of all or any parts of this option shall only be 
effective at such time that the sale of Common Shares pursuant to such exercise 
will not violate any state or federal securities or other laws.

          (d)  If there shall be any change in the Common Shares of the Company 
through merger, consolidation, reorganization, recapitalization, dividend in the
form of stock (of whatever amount), stock split or other change in the 
corporate structure of the Company, and all or any portion of the option shall 
then be unexercised and not yet expired, then appropriate adjustments in the 
outstanding option shall be made by the Company, in order to prevent dilution or
enlargement of option rights. Such adjustments shall include, where appropriate,
changes in the number of shares of Common Shares and the price per share subject
to the outstanding option.

                                      15
<PAGE>
 
          (e)  The Company shall at all times during the term of the option
reserve and keep available such number of shares as will be sufficient to
satisfy the requirements of this Agreement.

          (f)  if Employee shall dispose of any of the Common Shares of the 
Company acquired by Employee pursuant to the exercise of the option within two 
(2) years from the date this option was granted or within one (1) year after the
transfer of any such shares to Employee upon exercise of this option, then, in 
order to provide the Company with the opportunity to claim the benefit of any 
income tax deduction which may be available to it under the circumstances, 
Employee shall promptly notify the Company of the dates of acquisition and 
disposition of such shares, the number of shares so disposed of, and the 
consideration, if any, received for such shares. In order to comply with all 
applicable federal or state income tax laws or regulations, the Company may 
take such action as it deems appropriate to insure (i) notice to the Company of 
any disposition of the Common Shares of the Company within the time periods 
described above and (ii) that, if necessary, all applicable federal or state 
payroll, withholding, income or other taxes are withheld or collected from 
Employee.

          (g)  Employee agrees to disclose neither the contents nor any of the 
terms and conditions of this option to any other person, and agrees that such 
disclosure may result in both immediate termination of this option without the 
right to exercise any part thereof and termination of employment with the 
Company.

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed on the day and year first above written.

through merger, consolidation, reorganization, recapitalization, dividend in the
form of stock (of whatever amount), stock split or other change in the corporate
structure of the Company, and all or any portion of the option shall then be
unexercised and not yet expired, then appropriate adjustments in the outstanding

withholding obligations upon exercise of this option by (i) having the Company
withhold a portion of the shares of Common Stock otherwise to be delivered upon
exercise of such option having a fair market value equal to the amount of
federal and state income tax required to be withheld upon such exercise, in
accordance with the rules of the Committee, or (ii) delivering to the Company
shares of its Common Stock other than the shares issuable upon exercise of such
option with a fair market value equal to such taxes, in accordance with the
rules of the Committee.

executed on the day and year first above written.

[Logo Fieldworks Inc.]


                        SALES REPRESENTATIVE AGREEMENT 

     This non-exclusive Sales Representative Agreement is made as of  by and
between  located at  Phone () , Fax ()  ("REP"), and FIELDWORKS, INCORPORATED,
located at 9961 Valley View Road, Eden Prairie, MN 55344 ("FieldWorks").

     REP desires to promote the sales of certain products manufactured and sold
by FieldWorks and FieldWorks desires to have REP act as its representative in
the sale of such products.  In consideration of these promises and the covenants
contained in this Agreement, the parties agree as follows.

     1.  Appointment of REP

     1.1  FieldWorks hereby appoints REP as a non-exclusive sales representative
for FieldWorks' products set forth on Exhibit A (the "Products") as FieldWorks
may amend from time to time upon notice of REP.  REP shall be entitled to
promote the sale of the Products only in the territory and/or markets as defined
in Exhibit B.

     1.2  REP agrees to use its best efforts to promote the sale of the Products
and agrees to abide by all reasonable rules and regulations FieldWorks
establishes for its sales representatives from time to time.  REP agrees that,
during the term of this Agreement, REP will not sell, promote or offer for sale,
products which directly compete with or substitute for the Products.

     1.3  REP will solicit and take orders for the Products and transmit the
orders in writing to FieldWorks in the format approved by FieldWorks.
FieldWorks reserves the right to accept, reject, modify or cancel in whole or in
part any or all orders received and/or accepted for the Products, in its sole
discretion.  REP's authority under this Agreement is limited to the solicitation
and transmission to FieldWorks of orders, and REP has no right or authority to
make binding quotations, to accept any orders or to enter into any contracts or
agreements whatsoever for or on behalf of FieldWorks.  REP is an independent
contractor and not an agent or employee of FieldWorks.

     1.4  REP understands that FieldWorks' Products will be marketed to and used
by a wide variety of customers and in various market segments.  REP understands
that other sales organizations may be operating in the same territory and/or
markets as REP.

     2.  Commissions

     2.1  For sales made by REP for delivery within REP's territory and/or
market, FieldWorks shall pay REP the commission rate set forth in Exhibit C.
The commission shall become due and payable on the last day of the calendar
month following the month in which FieldWorks received payment in full for the
Product.

<PAGE>
 
         SALES REPRESENTATIVE AGREEMENT (TYPE CO. NAME, CONTRACT DATE)

     2.2  REP's commission rate and schedule, set forth in Exhibit C, is based
on the Net Sales Price of the Products sold.  As used herein, "Net Sales Price"
shall mean the actual price received by FieldWorks after any adjustments for
credits, returns, pricing adjustments, discounts, allowances, taxes, shipping
charges, non-recurring or other factors which reduce the amount actually
received by FieldWorks.  Non-discountable items defined in Exhibit A are also
non-commissionable.  Commission will be paid only once on each Product that is
sold.

     2.3  In the event of any dispute respecting commissions, commission
splitting, or any other commission issue, final resolution of the matter shall
be determined by FieldWorks' Sales Management.  Shares of the full commission
shall be awarded by FieldWorks based on the determination of the Sales
Management, in his/her sole discretion, based upon the sales and support efforts
of the parties involved.

     2.4  On sales of any Products, REP's commission is set forth in Exhibit C.
In the case of sales more than fifty (50) FW7000 Series Field WorkStations
("UNITS") or more than $400,000 USD per single Purchase Order, FieldWorks in its
sole discretion is entitled to increase customer discount only in order to get
customer sale.  In such cases, agreements on the amount of commission must be
made prior to FieldWorks' acceptance of the applicable order.  In the event no
written agreement is reached prior to acceptance of the order, the commission
will be awarded at a minimum rate of 5%.

     2.5  Sales to federal government organizations under FieldWorks' GSA
Authorized ADP Schedule Pricelist will be commissioned at a rate defined in
Exhibit C.

     2.6  REP acknowledges that FieldWorks may, in its sole discretion, pay
commissions to REP prior to receiving full and final payment from the customer.
REP agrees that, should FieldWorks not receive full payment for related Product
shipped (such as returns or charge backs), FieldWorks shall be entitled to
deduct such commission paid from other commissions to be paid to REP, at
FieldWorks' sole discretion.  In the event that there is no commission for
FieldWorks to deduct from, FieldWorks is entitled to seek full reimbursement.
REP agrees to cooperate and work with FieldWorks and the customer to secure the
business and payment.

     3.  Sales Objective

     3.1  REP understands and agrees that the establishment and achievement of a
Sales Quota is the essence of this Agreement, and that failure by REP to satisfy
its obligation under this Section shall constitute a material breach of this
Agreement, entitling FieldWorks to terminate this Agreement.  As a result, REP
agrees that it will obtain orders which are accepted by FieldWorks in which the
number of UNITS received by FieldWorks totals at least the number of UNITS or
the corresponding dollar amount specified in Exhibit D, as may be revised by the
parties for renewal terms of this Agreement.

     4.  Marketing and Business Obligations

     4.1  REP agrees (a) to submit quarterly to Field Works a six month rolling
sales forecast by model, (b) to follow up on leads supplied by FieldWorks within
5 days from the receipt thereof, (c) to actively sell and promote FieldWorks
products.

         SALES REPRESENTATIVE AGREEMENT (TYPE CO. NAME, CONTRACT DATE)

     4.2  REP agrees to initially purchase or lease one or more model of the
FW7000 Series or FW5000 Series to be used in sales and the promotion of the
Products at the current FieldWorks pricing, as set forth on Exhibit E.  REP and
FieldWorks will split 50-50 the costs for the up-keep of the demonstration
equipment which includes cosmetic appearance, factory upgrades and any other
product revisions that may occur during the term of this Agreement.

     4.3  REP agrees (d) to employ sufficient appropriately trained personnel at
REP's expense to represent and sell the Product adequately, and (e) to maintain
Products in a clean, safe and professional condition.

     4.4  REP agrees to, and hereby does, indemnify FieldWorks, its officers,
directors, employees and agents against and hold each of them harmless from any
and all claims, causes of action, damages, liabilities, costs and expenses
(including attorneys fees) arising from any breach by REP of any provision of
this Agreement.

     5.  Term and Termination

     5.1  Unless earlier terminated as provided in this Agreement, this
Agreement shall commence as of the date set forth above and shall terminate one
(1) year thereafter.  This agreement may be renewed for additional one (1 ) year
terms upon written agreement of the parties which agreement must include mutual
agreement as to the Sales Quota applicable to such renewal term.  If the parties
fail to agree in writing upon a renewal of this Agreement prior to the
expiration of this Agreement, this Agreement shall automatically expire and
terminate without further notice to either party.

     5.2  Either party can terminate this Agreement, with or without cause, on a
thirty (30) days prior written notice to the other party.

     5.3  If either party defaults in the performance of any material provision
of this Agreement, then the non-defaulting party may give written notice to the
defaulting party and, if the default is not remedied within thirty (30) days
following receipt of such notice, the Agreement will be terminated (material
breaches of this Agreement shall include, without limitation, failure to meet
the sales quota).

     5.4  FieldWorks shall pay REP commission on sales of Products resulting
from orders taken by REP during the 30-day notice period provided for in Section
5.2, provided that FieldWorks has received payment in full for such orders
within three months after the date of termination hereof.  Section 6 shall
survive any termination or expiration of this Agreement.

     6.  Confidentiality

     6.1  REP agrees that in the course of business dealings with FieldWorks,
certain valuable, proprietary and confidential information of FieldWorks is
likely to become known to REP, including, without limitation, such information
as equipment and software design information, documentation, prospect and
customer lists, key employee names, pricing, discount, and commission
structures, production volumes, and similar information (hereinafter
"proprietary information").  REP agrees that the proprietary information is the
sole and exclusive property of FieldWorks and shall be treated as confidential.
REP shall not disclose the proprietary information in any manner without the
prior written approval of FieldWorks and

<PAGE>
 
         SALES REPRESENTATIVE AGREEMENT (TYPE CO. NAME, CONTRACT DATE)

shall take reasonable measures to prevent any unauthorized disclosure by its
employees, agents, contractors or consultants during the term hereof including
appropriate individual nondisclosure agreements. REP may use the proprietary
information during the term of this Agreement only as permitted or required for
REP's performance hereunder.

     6.2  The obligations set forth in Section 6.1 shall not apply to any
information which is or becomes known to the general public through no fault of
REP, or which REP can prove by written records was known to REP at the time of
its receipt thereof from FieldWorks, or which has been rightfully obtained by
REP from a third party.  The provisions of Section 6 shall survive any
termination or expiration of this Agreement.

     7.  General

     7.1  This Agreement, including the Exhibits hereto which are incorporated
herein by reference, constitute the entire Agreement between the parties and
supersedes all prior and contemporaneous Agreements, understandings, negations
and discussions, whether written or oral.

     7.2  Any dispute between the parties arising out of or in connection with
this Agreement, if not resolved by mutual agreement between the parties, shall
be settled by binding arbitration under the rules of the Commercial Arbitration
Rules of the American Arbitration Association.  In the event of any such dispute
or difference, either party may give to the other party written notice that the
matter shall be settled by arbitration.  Such arbitration shall be conducted in
Hennepin County, Minnesota.  An award by arbitration may be entered as final

     7.4  All modifications, amendments, and/or waivers to this Agreement, less
exhibits, shall be in writing and signed by both parties.  No failure by either
party to take any action or assert any right hereunder shall be deemed to be a
waiver of such right in the event of the continuation or repetition of the
circumstances giving rise to such right.

     7.5  In no event shall FieldWorks be liable to REP, a customer or any other
party for loss of profits, indirect, special, consequential or incidental
damages arising out of this Agreement even if FieldWorks shall have been advised
of the possibility of such potential loss or damage by REP or REP's customers.
In no event shall FieldWorks be liable for any damages in excess of the
aggregate amounts actually paid by REP to FieldWorks under this Agreement.

     7.6  REP may not assign, delegate or transfer any of its rights or
obligations under this Agreement, without the prior written consent of
FieldWorks. Any attempted assignment, delegation or transfer by REP without such
consent shall be void.

jurisdiction to be invalid or unenforceable, such provision shall be deemed
stricken from the Agreement and the remainder of the Agreement shall continue in
full force and effect.

     FieldWorks welcomes your organization into the FieldWorks family. We would
like to show our appreciation by offering a one time signing bonus. Option 1: As

a cost effective alternative for some REP firms.

     This signing bonus program is our initial Demo program so we do require you
to purchase at least one (1) UNIT at the 35% off-list price of the FW7000 Series
or 25% of the FW5000 Series or lease one (1) UNIT. We realize that this is a
large amount of money to invest but we feel extremely confident that you will
pay for the cost of the UNIT within the first month of being our REP. We are so
confident, that if you don't sell a UNIT within thirty (30) days after receiving
your UNIT, we will reimburse you 100% guaranteed and terminate the REP Agreement
at that time.

                             TERMS AND CONDITIONS


INTRODUCTION:
FieldWorks, Inc. cosigns and manufactures portable Field WorkStations for field
professionals who demand six slot expandability in a very rugged package. The
Field WorkStations provide years of uninterrupted performance as long as they
are cared for and maintained within the specifications listed for the product.
All Field WorkStations carry a full one year parts and labor limited warranty.
For those customers who need to have an extended warranty, FieldWorks has made
this plan available.

PLAN DESCRIPTION:
The terms and conditions of this agreement ("the Plan") extend the rights and
privileges of FieldWorks' one-year warranty for a one to two year period
beginning on the start date set forth on the reverse side. The Plan covers the
Field WorkStation product line as well as the options that are sold with the
Field WorkStations.

In the event that any covered Field WorkStation or option does not satisfy the
foregoing warranty at any time during the term of the Plan coverage, repair or
replacement of that instrument or option will be provided by FieldWorks.

The Plan is available for purchase during the original warranty period and
becomes effective at the completion of the initial year's warranty. However, the
cost of the Plan is less when purchased at the time of the Field WorkStation's
purchase.

Products which are out of warranty will need to be recertified by the factory to
determine their acceptability under the program. A recertification fee is
required. If service work is required you will be notified for approval to
proceed (in the form of a purchase order) and the recertified fee will apply
towards the service work required.

herein.
