itemized account detailing the expenses on a form provided to Executive by MWS,

                                   TERMINATION

         5.1 Executive's employment with MWS shall terminate in accordance with
the following provisions:

         5.1 (a)  MWS may terminate Executive's employment as follows:

                  (i)      Upon at least thirty (30) days' written notice to
                           Executive, with or without cause, after the end of
                           the first year term of this Agreement.

                  (ii)     Upon the disability of Executive for a period of at
                           least ninety (90) business

<PAGE>

                           days, whether or not consecutive, during any twelve
                           (12) month period. For the purposes of this
                           Agreement, the term "disability" means any physical
                           or mental impairment of Executive, whether total or
                           partial, which prevents Executive, in the reasonable
                           judgment of MWS's Board of Directors, from carrying
                           out or performing the major duties of his employment.
                           Upon the request of MWS's Board of Directors,
                           Executive shall submit to examinations by a physician
                           or physicians, to assist MWS's Board of Directors in
                           determining whether Executive has been disabled for
                           purposes of this Agreement. The decision as to
                           Executive's disability, if made in good faith by
                           MWS's Board of Directors, shall be conclusive and
                           binding upon Executive.

         5.1 (b)  Executive may terminate employment with MWS upon at least
                  ninety (90) days' prior written notice to MWS after the end of
                  the first year term of this Agreement.

         5.1 (c)  Any other provision of this Agreement notwithstanding, MWS may
                  terminate Executive's employment without notice if the
                  termination is based on a violation of this Agreement, or on
                  fraud, embezzlement, securities law violation, material
                  violation or willful criminal violation of environmental laws
                  and regulations or an applicable agreement with a federal or
                  state environmental agency (including without limitation any
                  Compliance Agreement or other agreement/authorization with the
                  MPCA or WDNR), sexual harassment of fellow employees, or if
                  Executive takes employment in addition to that of MWS, in
                  competition with MWS, or if Executive is guilty of an act or
                  acts of insubordination, misconduct, dishonesty, or disloyalty
                  against MWS, or gross misconduct involving moral turpitude as
                  determined in the sole discretion of MWS.

         5.2 Employment will be deemed terminated upon the death of the
Executive.

                                    ARTICLE 6
                         PROTECTION OF TRADE SECRETS AND
                           CONFIDENTIAL BUSINESS DATA

         6.1 In the performance of his duties, Executive may become aware of,
either directly or indirectly, information of the following types regarding or
belonging to MWS which constitutes trade secrets or confidential business data:

                  (a)      Patterns, programs, devices, methods, techniques or
                           processes.

                  (b)      Products or components.

                  (c)      Merchandising aids, marketing or strategic planning
                           information.

                  (d)      Pricing or price structure, customers, potential
                           customers.

                  (e)      Research and development.

         6.2 The foregoing list of trade secrets and confidential business data
is not intended to be

<PAGE>


exclusive. From time to time during the term of his employment, Executive may
gain and has gained access to other information concerning MWS's business of
commercial value to MWS, which information shall be included in the definitions
under Section 6.1, above, even though not specifically listed. MWS believes that
such information constitutes trade secret information because MWS derives
economic value from the fact that such information is not generally known or
readily ascertainable by proper means by MWS's competitors or potential
competitors who may obtain economic value by its disclosure or use. The
provisions of this Article 6 apply to any form in which the subject information,
secrets or data may appear, whether written, oral or any other form of recording
or storage.

          6.3 Executive covenants and agrees that both during and after his
employment with MWS, the foregoing confidential business data and information
and trade secrets will not be communicated or disclosed by him (directly or
indirectly) to any person or entity, including but not limited to, the press,
other professionals, corporations, partnerships or the public. Executive further
agrees to never use such information for Executive's benefit or the benefit of
any other person, firm, corporation or entity, directly or indirectly. Executive
agrees to take reasonable security measures to prevent accidental disclosure and
industrial espionage. Executive further covenants and agrees that he will
faithfully abide by all rules and regulations established by MWS for insuring
the confidentiality of the foregoing information and data, including, but not
limited to, rules and regulations:

                  (a)      Limiting access to authorized personnel;

                  (b)      Limiting copying of any writing or recording;

                  (c)      Requiring storage of documents in secure facilities
                           provided by MWS and limiting safe or vault lock
                           combinations or keys to authorized personnel; and

                  (d)      Checkout and return or other procedures or
                           regulations promulgated by MWS from time to time.

The obligations of this Section 6.3 shall survive Executive's employment with
MWS and continue until the information at issue is no longer confidential and
becomes generally publicly known, other than as a direct or indirect result of
the breach of this Agreement by Executive or a breach of a confidentiality
obligation owed to MWS by any other person or entity.

         6.4 Upon termination of his employment with MWS, whether voluntary or
involuntary, Executive will return to MWS any and all written or other recorded
form of the foregoing information and data, and will take with him, upon leaving
MWS' place of business, no documents, writings, recordings or reproduction in
any form which may have been entrusted to him during the course of his
employment or to which he had access or possession.

                                    ARTICLE 7
                            INVENTIONS OR DISCOVERIES

         7.1 Executive acknowledges that inventions or other discoveries may be
developed, conceived or otherwise made by Executive during employment with MWS.
Executive agrees that all such inventions or other discoveries shall be the
exclusive property of MWS. With respect to all such

<PAGE>


inventions or other discoveries, Executive agrees to:

                  (a)      Keep accurate, complete and timely records, which
                           shall be MWS's property and be retained on MWS's
                           premises; and

                  (b)      Promptly and fully disclose and describe all such
                           inventions or other discoveries to MWS; and

                  (c)      Assign (and Executive does hereby assign) to MWS all
                           of Executive's rights to these inventions or other
                           discoveries, and to application for letters patent or
                           copyrights in all countries and to letters patent or
                           copyrights granted upon these inventions or other
                           discoveries in all countries; and

                  (d)      To do such other acts as may be necessary in the
                           opinion of MWS to preserve property rights to these
                           inventions or other discoveries against forfeiture,
                           abandonment or loss and to obtain and maintain
                           letters patent or copyrights and to vest the entire
                           right and title thereto exclusively in MWS.

         7.2 The obligations of this Article 7 shall continue beyond the
termination of Executive's employment with MWS with respect to inventions or
other discoveries conceived or otherwise developed during Executive's employment
and shall be binding upon assigns, executors, administrators and other legal
representatives.

         7.3 MWS hereby notifies Executive, and Executive understands and
agrees, that the foregoing terms of this Article 7 do not apply to any invention
or other discovery for which no equipment, supplies, facility, or trade secret
information of MWS was used and that were developed entirely on Executive's own
time, and (a) that does not relate (1) directly to MWS's business or (2) to
MWS's actual or demonstrably anticipated business research or development, or
(b) that does not result from any work performed by Executive for MWS.

                                    ARTICLE 8
                             COVENANT NOT TO COMPETE

         8.1 In view of the compensation and benefits set forth herein, as well
as Executive's equity participation in MWS, Executive agrees that at no time
during the term of this Agreement and Executive's employment with MWS and for a
period of one (1) year following the termination of Executive's employment
(whether voluntary or involuntary) (the "Noncompete Period"), will Executive,
directly or indirectly, without the prior written consent of the MWS Board of
Directors, (a) solicit or do competitive business with any person or entity that
is or was a customer or vendor of MWS within the twelve (12) months prior to the
date of termination, or (b) engage within the United States or Canada in any
similar or related business in competition with MWS or have any direct or
indirect interest, whether as a proprietor, partner, employee, shareholder,
principal, agent, consultant, director, officer or in any other capacity or
manner whatsoever, in any enterprise that shall so engage. Executive recognizes
and agrees that the geographic scope of this restriction is reasonable because
MWS's business will be

<PAGE>


conducted on a national and international scale and is not limited to a
particular geographic area within the United States or Canada.

         8.2 Executive shall not, during the Noncompete Period, directly or
indirectly, hire for employment or solicit, induce or otherwise attempt to cause
any individual who is an employee of MWS during the term of his or her
employment to leave the employ of MWS for any reason whatsoever; provided,
however, that this provision shall not apply to any such employee whose
employment or relationship with MWS has been terminated for at least six (6)
months prior to such hiring or other restricted activity. The term "employment"
for purposes of this paragraph means an arrangement for services as a full-time
or part-time employee, independent contractor, agent or otherwise.

                                    ARTICLE 9
                                INJUNCTIVE RELIEF

         9.1 The parties acknowledge that MWS will suffer irreparable harm if
Executive breaches this Agreement, either during or after its term. Accordingly,
MWS shall be entitled, in addition to any other rights and remedy it may have,
at law or equity, to any injunction, without the posting of a bond or other
security, enjoining or restraining Executive from any violation of this
Agreement, and Executive hereby consents to MWS's right to the issuance of such
injunction. In any proceeding by MWS to enforce any provision of this Agreement,
MWS shall, in addition to any injunctive relief to which it may be entitled, be
awarded damages to be determined by a court of competent jurisdiction as well as
all court costs, disbursements, expenses and attorneys' fees incurred by MWS.

         9.2 In the event Executive violates the terms of Article 8, the
Noncompete Period shall be extended for one (1) year from and after the later
of:

                  (a)      The date which Executive ceases any violation; or

                  (b)      The date on which a court issues an order or judgment
                           enforcing the terms of the covenant.

         9.3 In the event a court of competent jurisdiction determines that a
provision of Article 8 above is unreasonable, it may limit such provision to the
extent it deems reasonable, without declaring the provision invalid in its
entirety. This provision shall not be construed as an admission by MWS, but is
only included to provide MWS with the maximum possible protection consistent
with the right of Executive to earn a livelihood subsequent to the termination
of his employment.

                                   ARTICLE 10
                                  MISCELLANEOUS

         10.1 Governing Law. This Agreement shall be governed according to the
laws of the State of Minnesota.

         10.2 Successors. This Agreement is personal to Executive and Executive
may not assign or transfer any part of his rights or duties hereunder, or any
compensation due to him hereunder, to any other person or entity. This Agreement
may be assigned by MWS.

<PAGE>


         10.3 Waiver. The waiver by MWS of the breach or nonperformance of any
provision of this Agreement by Executive will not operate or be construed as a
waiver of any future breach or nonperformance under any such provision of this
Agreement or any similar agreement with any other employee.

         10.4 Modification. This Agreement supersedes and replaces any and all
prior and written understandings, if any, between the parties relating to the
subject matter of this Agreement, including any previous employment contract
which is hereby revoked. The parties agree that this Agreement is the entire
understanding and agreement between the parties.


         IN WITNESS WHEREOF the following parties have executed the above
Employment Agreement as of the day and year first above written.
