                                    WARRANT
                                  TO PURCHASE
                             SHARES OF COMMON STOCK


     For value received, and in consideration of the execution and delivery of
the Securities Purchase Agreement between the issuer of this Warrant and
Industrial-Works Holding Corp., a Delaware corporation dated November 20, 1999
("Securities Purchase Agreement"), which has been transferred by operation of
law to Industrial-Works Holding Co., LLC ("Purchaser") Purchaser and its
successors or assigns ("Holder"), is entitled to purchase from FieldWorks,
Incorporated, a Minnesota corporation (the "Company'), up to 250,000 fully paid
and nonassessable shares of the Company's common stock, $.001 par value per
share or such greater or lesser number of such shares as may be determined by
application of the anti-dilution provisions of this Warrant, at the price of One
Dollar $1.00 per share, subject to adjustment as  noted below (the "Warrant
Exercise Price").

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

     This Warrant is subject to the following terms and conditions:

     1.  Exercise.  The rights represented by this Warrant may be exercised by
the Holder, in whole or in part, by written election, in the form set forth
below, by the surrender of this Warrant (properly endorsed if required) at the
principal office of the Company, and by payment to it by cash, certified check
or bank draft of the Warrant Exercise Price for the
<PAGE>

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

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

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

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

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

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

                                      -2-
<PAGE>

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

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

                                      -3-
<PAGE>

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

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

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

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

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

                                      -4-

     8.  Notices.  All demands and notices to be given hereunder shall be

                              Registration Rights

determination plus (ii) with respect to the Warrant owned by such Eligible
Holder, the number of shares of Common Stock issued or issuable upon exercise of
such Warrant as of the date of determination (in each case, whether or not such

respective Permitted Transferees.

with respect to, or in exchange for or in replacement of, such above-described
securities.  Notwithstanding the foregoing, Registrable Securities shall not
include any securities sold by a person to the public either pursuant to a
registration statement or Rule 144, or sold in a private transaction in which
the transferor's rights under this Exhibit A is are not assigned.

                                      A-1

     2.  Demand Registrations

          (a)  Required Threshold.

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

          (b) Number of Demand Registrations.

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

                                      A-2
<PAGE>

          (c)  Deferral by Company.

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

          (d)  Participation.

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

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

                                      A-3
<PAGE>

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

          (e)  Underwriter's Cutback.

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

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

          (f)  Managing Underwriter.

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

                                      A-4
<PAGE>

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

     3.  Piggyback Registrations

          (a)  Participation.

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

          (b)  Underwriter's Cutback.

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

          (c)  Company Control.

          The Company may decline to file a Registration Statement after giving

Registration Statement

                                      A-5

after filing and after such notice, but prior to the effectiveness thereof;
provided that the Company shall promptly notify each Eligible Holder in writing
of any such action and provided further that the Company shall bear all expenses
incurred by each Eligible Holder or otherwise in connection with such withdrawn
Registration Statement.

     4.  Registration on Form S-3

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

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

          (b) Application of Certain Provisions.

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

     5.  Hold-back Agreements

          (a) By Holders of Registrable Securities.

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

                                      A-6

          (b)  By the Company and Others.

          The Company agrees:

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

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

     6.   Registration Procedures

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

supplement thereto to which the Eligible Holders or the underwriters, if any,
shall reasonably object;

          (b) prepare and file with the SEC such amendments and post-effective

<PAGE>

be requested by any underwriter of Registrable Securities or as may be required
by the rules, regulations or instructions applicable to the registration form
used by the Company or by the Securities Act or rules and regulations thereunder

covered by such Registration Statement are sold in accordance with the intended

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

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

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

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

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

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

twenty-five percent (25%) of the Registrable Securities then outstanding, as
promptly as practicable incorporate in a supplement or post-effective amendment
such information as the managing underwriter and such Eligible Holder agree
should be included therein relating to the sale of

anything else necessary or advisable to enable from a legal perspective the
disposition in such jurisdictions of the Registrable Securities covered by the
