               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference.
         ---------------------------------------

               The following documents, which have been filed by Fieldworks,
Incorporated (the "Company") with the Securities and Exchange Commission, are
incorporated by reference in this Registration Statement, as of their respective
dates:

               (a)  The Company's prospectus filed pursuant to Rule 424(b) of
               the Securities Act of 1933, as amended (the "Securities Act of
               1933"), on March 20, 1997.

               (b)  Not applicable.

               (c)  The description of the Company's capital stock contained in
               the registration statement on Form 8-A filed by the Company under
               the Securities Exchange Act of 1934, as amended (the "Exchange
               Act").

               All documents filed by the Company pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Exchange Act, subsequent to the date hereof and prior
to the filing of a post-effective amendment which indicates that all securities
offered hereby have been sold or which deregisters all securities remaining
unsold, shall be deemed to be incorporated by reference herein and to be a part
hereof from the respective dates of filing of such documents.

Item 4.  Description of Securities.
         -------------------------

               Not applicable.

Item 5.  Interests of Named Experts and Counsel.
         --------------------------------------

               Not applicable.

Item 6.  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 


                                     II-1
<PAGE>
 
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.

Item 9.  Undertakings.
         ------------

A.       The undersigned registrant hereby undertakes:

         (1)      To file, during any period in which offers or sales are being 
made, a post-effective amendment to this registration statement:
                  
                  (i)   To include any prospectus required by Section 10(a)(3)
                        of the Securities Act of 1933;

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

                                     II-2
<PAGE>
 
                  (iii) To include any material information with respect to the
                        plan of distribution not previously disclosed in the
                        registration statement or any material change to such
                        information in the registration statement;

provided, however, that paragraphs A(1)(i) and A(1)(ii) above will not apply if
--------  -------
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.

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

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

B.       The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

C.       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
Securities Act of 1933 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 other
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
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

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

               The following documents, which have been filed by Fieldworks,
Incorporated (the "Company") with the Securities and Exchange Commission, are
incorporated by reference in this Registration Statement, as of their respective

               (a)  The Company's prospectus filed pursuant to Rule 424(b) of

               Act").

               All documents filed by the Company pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Exchange Act, subsequent to the date hereof and prior
to the filing of a post-effective amendment which indicates that all securities

Item 4.  Description of Securities.

               Not applicable.

Item 5.  Interests of Named Experts and Counsel.
         --------------------------------------

               Not applicable.

Item 6.  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 

                                     II-1
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.

Item 9.  Undertakings.
         ------------

A.       The undersigned registrant hereby undertakes:

         (1)      To file, during any period in which offers or sales are being 
made, a post-effective amendment to this registration statement:
                  
                  (i)   To include any prospectus required by Section 10(a)(3)
                        of the Securities Act of 1933;

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

                                     II-2
(iii) To include any material information with respect to the
                        plan of distribution not previously disclosed in the
                        registration statement or any material change to such
                        information in the registration statement;

provided, however, that paragraphs A(1)(i) and A(1)(ii) above will not apply if
--------  -------
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.

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

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

B.       The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

C.       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
Securities Act of 1933 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 other
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
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
