contribution level of Executive.
| | -----------------------------------------------------------------------------------------------------------------------------

| | (c)     The Executive shall also be entitled to the
payments and benefit continuation in paragraphs (a) and (b) herein, if

5.)     SUCCESSORS;
BINDING AGREEMENT; ASSIGNMENT. The Company shall require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Company to expressly
assume and agree in writing to perform this Agreement in the same manner and to
the same extent that the Company would be required to perform it if no such
succession had taken place. The Executive must be given the same position with
the same authority, powers and responsibilities with respect to the subsidiary
or subdivision which operates the business of the Company as it exists on the
date of such business combination. Failure of the Company to obtain such express
assumption and agreement at or prior to the effectiveness of any such succession
shall be a breach of this Agreement and shall entitle the Employee to
compensation and benefits from the Company in the same amount and on the same
terms to which the Employee would be entitled hereunder if the Company
terminated the Employees employment without Cause pursuant to a Change of
Control, except that all options will be immediately vested. For purposes of
implementing the foregoing, the date on which any such succession becomes
effective shall be deemed the date of termination. As used in this Agreement,
 the Company shall mean the Company as hereinbefore defined and any
successor to its business or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise. The Company may not
assign this Agreement, (i) except in connection with, and to the acquiror
of, all or substantially all of the business or assets of the Company, and then
only if such acquiror expressly assumes and agrees in writing to perform this
Agreement as provided in this paragraph, and (ii) except in connection with
the Company becoming a wholly-owned subsidiary in which event the Company may
assign this Agreement and all of the Companys rights and obligations
hereunder its parent company. The Executive may not assign his rights or
delegate his duties or obligations under this Agreement.

6.)
     NOTICES. Any notice or other communications
under this Agreement shall be in writing, signed by the party making the same,
and shall be delivered personally or sent by certified or registered mail,
postage prepaid, addressed as follows:

|If to Executive:   | Greg Jensen

or to such other address or

shall be deemed given on the date personally delivered or mailed.

7.)     FULL
SETTLEMENT AND LEGAL EXPENSES. The Companys obligation to make the
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off (except for loans or other
amounts owed by Executive to the Company) counter-claim, recoupment, defense or
other claim, right or action which the Company may have against

Executive or others. In no
event shall Executive be obligated to seek other employment or take any other
action by way of mitigation of the amounts payable to Executive under any of the
provisions of this Agreement. No remuneration paid or payable to Executive from
subsequent employment the Executive may obtain will be offset against the
Companys obligations for payment under this Agreement. The prevailing
party shall be entitled to recover all legal fees and expenses which such party
may reasonably incur as a result of any legal proceeding relating to the
validity, enforceability, or breach of, or liability under, any provision of
this Agreement or any guarantee of performance (including as a result of any
contest by Executive about the amount of any payment pursuant to
paragraph 4 of this Agreement), plus in each case interest at the
applicable Federal Rate provided for in Section 7872(f)(2) of the Code.

8.)     GOVERNING
LAW AND JURISDICTION. This Agreement shall be interpreted and enforced in
accordance with the laws of the State of Minnesota. Courts in the State of
Minnesota shall be the exclusive forum for resolving any disagreements or
disputes relating to this Agreement.

9.)     SEVERABILITY.
Whenever possible, each provision of this Agreement shall be interpreted in such
manner as to be effective and valid, but if any one or more of the provisions
contained in this Agreement shall be invalid, illegal or unenforceable in any
respect for any reason, the validity, legality and enforceability of any such
provisions in every other respect and of the remaining provisions of this
Agreement shall not be in any way impaired.

10.)     ENTIRE
AGREEMENT. This Agreement (including all Exhibits) contains the entire
agreement of the parties with respect to the subject matter contained in this
Agreement. There are no restrictions, promises, covenants, or undertakings
between the Company and Executive, other than those expressly set forth in this
Agreement. This Agreement supersedes all prior agreements and understandings
between the parties. This Agreement may not be amended, discharged, waived, or
modified except in writing executed by the parties.

11.)     COUNTERPARTS
AND FAX SIGN. This Agreement may be executed in counterparts, and each such
duly executed counterpart shall be of the same validity, force and effect as the
original. Facsimile copies of signatures shall constitute valid and binding
obligations of the signing party once delivered by facsimile to the other party.

IN
WITNESS WHEREOF, the undersigned have executed this Agreement as of the day and year
first above written.
