               (iv)  any other willful act or omission on your part which is
          materially injurious to the financial condition or business reputation
          of the Company or any of its subsidiaries;

               (v)   you have breached any provision of this Employment
          Agreement contained in Paragraphs 6, 7 and 8 hereof; or

               (vi)  you have breached any provision of this Employment
          Agreement (other than paragraphs 6, 7 or 8 hereof) and such breach
          will not have been cured within sixty days after notice thereof from
          the Company to you.

     (d)  Without Cause. Your employment hereunder may be terminated at any time

provide the benefits provided hereunder, in each case for the Severance Period;
provided, however, that if the Date of Termination with respect to such

in Control (as defined below), then you will not be entitled to receive, nor
will the Company be obligated to pay, the Severance Amount, or any salary or

Exchange Act of 1934), other than the Company, J.W. Childs Equity Partners,
L.P., J.W. Childs Equity Partners III, L.P., or any of their respective
affiliates, any trustee or other fiduciary holding securities under an employee
benefit plan of the Company or any of its subsidiaries, or any corporation
owned, directly or indirectly, by the stockholders of the Company, in
substantially the same proportions as their ownership of stock of the Company,
acquires, in a single transaction or a series of transactions (i) "beneficial
ownership" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934)
of securities representing more than 50% of the combined voting power of the
Company (or, prior to a public offering, more than 50% of the Company's
outstanding shares of Common Stock), or (ii) substantially all of the assets of
the Company."

     (e)  Resignation Without Good Reason. You may terminate your employment
hereunder upon sixty days' prior written notice to the Company, without Good
Reason (as defined herein). In the event of such termination, all of your rights
to payment (other than payment for services already rendered) and any other
benefits otherwise due hereunder will cease upon the Date of Termination.

     (f)  Resignation For Good Reason. You may terminate your employment
hereunder at any time upon thirty days' written notice to the Company, for Good
Reason. In the event of such termination, the Company will continue to pay you
your base salary though the date which is eighteen months from the Date of
Termination; provided, however, that if the Date of

Termination with respect to such termination by you pursuant to this Section
4(f) is on or after a Change in Control, then you will not be entitled to
receive, nor will the Company be obligated to pay, any salary or severance
amount or continue any benefits hereunder on or after such Date of Termination.
You will have "Good Reason" for termination of your employment hereunder if,
other than for Cause, any of the following has occurred:

               (i)   your base salary has been reduced--(other than in
          connection with an across-the-board reduction (of approximately the
          same percentage) in executive compensation to Executive Employees
          imposed by the Board in response to negative financial results or
          other adverse circumstances affecting the Company;

               (ii)  the Company has required you to relocate outside the
          greater Minneapolis, Minnesota area;

               (iii) your illness, that in the good faith determination of the
          Board of Directors of the Company is likely to result in you becoming
          disabled and unable to continue your employment with the Company; or

               (iv)  the Company has breached this Employment Agreement in any
          material respect.

     (g)  Date and Effect of Termination. The date of termination of your
employment hereunder, pursuant to this Paragraph 4, will be, (i) in the case of
Paragraph 4(a), the date of your death, (ii) in the case of Paragraphs 4(b), (c)
or (d), the date specified as your last date of employment in the Company's
notice to you of such termination or (iii) in the case of Paragraph 4(e) or
4(f), the date specified in your notice to the Company of such termination (in
each case, the "Date of Termination"). Upon any termination of your employment
hereunder pursuant to this Paragraph 4, you will not be entitled to any further
payments or benefits of any nature pursuant to this Employment Agreement, or as
a result of such termination, except as specifically provided for in this
Employment Agreement, the Stockholders' Agreement between the Company and the
equity security holders of the Company, in any stock option plans adopted by the
Company in accordance with Paragraph 3(b) hereof, or as may be required by law.

     5.   Acknowledgment. You agree and acknowledge that in the course of
rendering services to the Company and its clients and customers, you will have
access to and become acquainted with confidential information about the
professional, business and financial affairs of the Company and its affiliates.
You acknowledge that the Company is engaged and will be engaged in a highly
competitive business, and the success of the Company in the marketplace depends
upon its good will and reputation for quality and dependability. You agree and
acknowledge that reasonable limits on your ability to engage in activities
competitive with the

<PAGE>

Mr. David E. Dovenberg

Company are warranted to protect its substantial investment in developing and
maintaining its status in the marketplace, reputation and good will. You
recognize that in order to guard the legitimate interests of the Company and its
affiliates, it is necessary for the Company to protect all confidential
information. The existence of any claim or cause of action by you against the
Company shall not constitute and shall not be asserted as a defense to the
enforcement by the Company of this Employment Agreement. You further agree that
your obligations under Paragraphs 6, 7 and 8 hereof shall be absolute and
unconditional.

     6.   Confidentiality. You agree that during and at all times after the
Term, you will keep secret all confidential matters and materials of the Company
(including its subsidiaries and affiliates), including, without limitation,
know-how, trade secrets, real estate plans and practices, individual office
results, customer lists, pricing policies, operational methods, any information
relating to the Company (including any of its subsidiaries and affiliates)
products, processes, customers and services and other business and financial
affairs of the Company (collectively, the "Confidential Information"), to which
you had or may have access and will not disclose such Confidential Information
to any person other than the Company, their respective authorized employees and
such other person to whom you have been instructed to make disclosure by the
Board, in each case only to the extent required in the course of your service to
the Company hereunder or as otherwise expressly required in connection with
court process. "Confidential Information" will not include any information which
is in the public domain during or after the term, provided such information is
not in the public domain as a consequence of disclosure by you in violation of
this Employment Agreement.

     7.   Non-competition. During the Prohibition Period (as hereinafter
defined), you will not, in any capacity, whether for your own account or for any
other person or organization, directly or indirectly, within the United States
and Canada (a) own, operate, manage or control, (b) serve as an officer,
director, partner, employee, agent, consultant, advisor or developer or in any
similar capacity to, or (c) have any financial interest in, or aid or assist
anyone else in the conduct of, any person or enterprise which is engaged in a
business competitive with the activities of the business actually conducted by
the Company. As used herein, "Prohibition Period" means the period from and
after the date hereof to and including the later of (i) the last day of the Term
or (ii) the last day of the Severance Period.

     8.   Non-solicitation. During the Prohibition Period, you will not,
directly or indirectly, hire, recruit, solicit, call upon, divert, take away,
entice or in any other manner persuade or attempt to do any of the foregoing
with respect to, any employee, independent contractor, dealer, supplier, client,
customer or business contact of the Company or any of its subsidiaries to
discontinue his or her position or relationship, or violate any agreement, with
the Company or any of its subsidiaries as employee, independent contractor,
dealer, supplier, client,

customer or business contact, except with the prior written consent of the
Board, which consent will be given at the sole discretion of the Board.

     9.   Modification. You agree and acknowledge that the duration, scope and
geographic area of the covenants described in Paragraphs 6, 7 and 8 are fair,
reasonable and necessary in order to protect the good will and other legitimate
interest of the Company and its subsidiaries, that adequate consideration has
been received by you for such obligations, and that these obligations do not
prevent you from earning a livelihood. If, however, for any reason any court of
competent jurisdiction determines that any restriction contained in Paragraphs
6, 7 or 8 are not reasonable, that consideration is inadequate or that you have
been prevented unlawfully from earning a livelihood, such restriction will be
interpreted, modified or rewritten to include as much of the duration, scope and
geographic area identified in such Paragraphs 6, 7 or 8 as will render such
restrictions valid and enforceable.

     10.  Equitable Relief. You acknowledge that the Company will suffer
irreparable harm as a result of a breach of this Employment Agreement by you for
which an adequate monetary remedy does not exist and a remedy at law may prove
to be inadequate. Accordingly, in the event of any actual or threatened breach
by you of any provision of this Employment Agreement, the Company will, in
addition to any other remedies permitted by law, be entitled to obtain remedies
in equity, including without limitation specific performance, injunctive relief,
a temporary restraining order and/or a permanent injunction in any court of
competent jurisdiction, to prevent or otherwise restrain any such breach without
the necessity of proving damages, posting a bond or other security, and to
recover any and all costs and expenses, including reasonable counsel fees,
incurred in enforcing this Employment Agreement against you, and you hereby
consent to the entry of such relief against you and agree not to contest such
entry. Such relief will be in addition to and not in substitution of any other
remedies available to the Company. The existence of any claim or cause of action
by you against the Company or any of its subsidiaries, whether predicated on
this Employment Agreement or otherwise, will not constitute a defense to the
enforcement by the Company of this Employment Agreement. You agree not to defend
on the basis that there is an adequate remedy at law.

     11.  Successors; Assigns; Amendment; Notice. This Employment Agreement will
be binding upon and will inure to the benefit of the Company and will not be
assigned by the Company without your prior written consent. This Employment
Agreement will be binding upon you and will inure to the benefit of your heirs,
executors, administrators and legal representatives, but will not be assignable
by you. This Employment Agreement may be amended or altered only by the written
agreement of the Company and you. All notices or other communications permitted
or required under this Employment Agreement will be in writing and will be
deemed to have been duly given if delivered by hand, by facsimile transmission
to the Company (if confirmed) or mailed (certified or registered mail, postage
prepaid, return receipt

     12.  Entire Agreement. This Employment Agreement embodies the entire
agreement and understanding between you and the Company with respect to the
subject matter hereof and supersedes all such prior agreements and
understandings.

     13.  Severability. If any term, provision, covenant or restriction of this
Employment Agreement is held by a court of competent jurisdiction to be invalid,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Employment Agreement will remain in full force and effect
and will in no way be affected, impaired or invalidated.

     14.  Governing Law. This Employment Agreement will be governed by and
construed and enforced in accordance with the laws of state of Minnesota
applicable to contracts made and to be performed in such state without giving
effect to the principles of conflicts of laws thereof.

     15.  Counterparts. This Employment Agreement may be executed in two or more
counterparts, each of which will be deemed an original but all of which together
will constitute one and the same instrument, and all signatures need not appear
on any one counterpart.
