to the Stockholder (the "Repurchase Notice"). The closing of the repurchase of
such Shares shall be held (a) not earlier than five (5) days nor later than
thirty (30) days after delivery of the Repurchase Notice if such repurchase is

five (5) days nor later than thirty (30) days after determination of the Common
Equity Value if such repurchase is being made in connection with a Termination
of Employment (other than a Termination of Employment prior to the Bonus Date).
The Company's repurchase rights under Section 3.1 shall lapse if not exercised
within the time periods (if any) specified above in accordance with the
provisions hereof, except as otherwise provided in Section 7 hereof. Upon
delivery by the Company of the repurchase price for the Shares being repurchased
hereunder in


                                       -5-

<PAGE>

accordance with Section 8 hereof, all of the Shares being repurchased shall no
longer be deemed to be outstanding, all of the Stockholder's rights with respect
to such Shares shall terminate with the exception of the right of the
Stockholder to receive the repurchase price in exchange therefor pursuant to
this Section 3.2, and the Stockholder hereby appoints the Company as his
attorney-in-fact to take all actions necessary and sign all documents required
to cancel such Shares on its books and records.

          3.3. APPRAISAL. Within fifteen (15) days following his receipt of a
Repurchase Notice from the Company in respect of a repurchase of the Shares
pursuant to Section 3.1 (a) hereof, the Stockholder shall select three (3)
Independent Appraisers that the Stockholder proposes to determine the Common
Equity Value for purposes of this Agreement and shall notify the Company in
writing of such selection (the "Stockholder Appraiser Notice"). The Company
shall select one (1) of the Independent Appraisers listed in the Stockholder
Appraiser Notice and use reasonable commercial efforts to promptly engage, at
the cost and expense of the Company, such Independent Appraiser to determine the
Common Equity Value for purposes of this Agreement. The terms of such engagement
shall provide that the Independent Appraiser shall complete its determination of
the Common Equity Value within 45 days of engagement by the Company. The Company
shall not be required to select any Independent Appraiser from a Stockholder
Appraiser Notice unless the Stockholder Appraiser Notice includes three (3)
Independent Appraisers. If the Stockholder has not provided a Stockholder
Appraiser Notice which complies with the requirements of this Section 3.3 within
thirty (30) days following the Stockholder's receipt of the Repurchase Notice,
the Board shall in good faith select an Independent Appraiser to determine the
Common Equity Value. Any determination of the Common Equity Value by an
Independent Appraiser pursuant to this Section 3.3 shall be final, conclusive
and binding upon the parties.

          4. RESTRICTIONS ON TRANSFER. Except as otherwise expressly provided in
the Stockholder Agreement, the Stockholder may not sell, assign, transfer,
pledge or otherwise dispose of ("Transfer") any of the Shares, either
voluntarily or involuntarily or by operation of law, except to the Company or
any of its Subsidiaries. On and after the time the Company completes a Public
Sale, all of the restrictions on Transfer and the repurchase rights of the
Company contained herein (including, without limitation, the repurchase rights
of the Company pursuant to Section 3 hereof), shall cease to apply to any
Shares. On and after the completion of a Target Disposition Event, all of the
repurchase rights of the Company contained herein (including, without
limitation, the repurchase rights of the Company pursuant to Section 3 hereof),
shall cease to apply to any Shares. Upon any permitted Transfer of the Shares,
the transferee of the Shares shall execute and deliver to the Company an
agreement containing repurchase provisions substantially the same as those
contained herein.

          5. INVESTMENT REPRESENTATIONS. (a) The Stockholder represents that the
Shares are being acquired by him for his own account for investment and not with
a view to the distribution thereof. The Stockholder understands that the Shares
have not been registered under the Securities Act of 1933, as amended (the
"Act"), on the grounds that the offer and sale of the Shares to him are exempt
from the registration requirements of the Act under Section 4(2) thereof as a
transaction not involving any public offering of the Shares. The


                                       -6-
<PAGE>

Stockholder understands that the Company's reliance on such exemption is
predicated in part on the representations of the Stockholder which are contained
herein.

          (b) The Stockholder understands that he must bear the economic risk of
his investment in the Shares for an indefinite period of time because the Shares
have not been registered under the Act and, therefore, cannot be sold unless
they are subsequently registered under the Act or an exemption from such
registration is available. The Stockholder agrees that he will not offer to
Transfer any of the Shares except as expressly permitted by this Agreement and
then only after the Company has received an opinion of its counsel that such
offer or Transfer is not in violation of the registration requirements of the
Act or other applicable law.

          (c) The Stockholder represents that he is an "accredited investor" (as
defined in Rule 501 under the Act) and a resident of the State of Minnesota.

          6. LEGENDS; STOP TRANSFER. (a) Each certificate representing the
Shares shall bear legends in or substantially in the following form:

          "THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED. NO TRANSFER, SALE OR
          OTHER DISPOSITION OF THESE SHARES MAY BE MADE UNLESS A REGISTRATION
          STATEMENT WITH RESPECT TO THESE SHARES HAS BECOME EFFECTIVE UNDER SAID
          ACT, OR THE COMPANY HAS BEEN FURNISHED WITH AN OPINION OF COUNSEL
          SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

          THE SHARES EVIDENCED BY THIS CERTIFICATE ARE ALSO SUBJECT TO CERTAIN
          REPURCHASE RIGHTS IN FAVOR OF THE COMPANY AND CERTAIN PROVISIONS
          REGARDING RESTRICTIONS UPON TRANSFER CONTAINED IN A RESTRICTED STOCK
          PURCHASE AGREEMENT, DATED AS OF JUNE 17, 2005, COPIES OF WHICH WILL BE
          FURNISHED BY THE COMPANY TO THE HOLDER OF THE SHARES EVIDENCED BY THIS
          CERTIFICATE UPON WRITTEN REQUEST AND WITHOUT CHARGE."

          (b) In addition, the Company shall make a notation regarding the
restrictions on transfer of the Shares in the stock books of the Company, and
such Shares shall be transferred on the books of the Company only if and when
transferred or sold in compliance with all of the terms and conditions of this
Agreement.

          7. REPURCHASE RESTRICTIONS.

          7.1. CONTRACTUAL RESTRICTIONS ON REPURCHASE. Notwithstanding any
provision to the contrary in Section 3, if the Company is prohibited by the
terms of any of the financing agreements of the Company or its Subsidiaries with
their lenders from making any payments of any portion of the repurchase price
for the Shares in cash, the Company shall be


                                       -7-

<PAGE>

entitled to complete the repurchase of such Shares by delivering to the
Stockholder (or any transferee) a promissory note for that portion of the
repurchase price, payment of which is prohibited. Each such promissory note
shall (i) bear interest at the rate of five percent (5%) per annum, (ii) provide

subordination provisions, provide for the payment in full of the principal
evidenced thereby upon the sale of substantially all of the assets or stock of
the Company.

          7.2. IMPAIRMENT OF CAPITAL. If even after giving effect to the
provisions of Section 7.1 hereof, the Company is prohibited by the terms of any
of the financing agreements of the Company or any of its Subsidiaries with their
lenders from issuing a promissory note for the balance of the repurchase price
as contemplated by Section 7.1 or is prohibited by law from repurchasing any
Shares which it is obligated or has elected to repurchase hereunder due to any
existing or prospective impairment of its capital, the closing of such
repurchase shall be delayed until the first date on which the Company is
permitted by the terms of any such financing agreements to repurchase such
Shares and has sufficient capital to lawfully repurchase such Shares (the
"Delayed Closing Date"). In the event of any such delay, (i) the Company will be
obligated to pay, on the Delayed Closing Date, interest on the repurchase price
for such Shares, at the rate of five percent (5%) per annum from the date on
which the closing of the repurchase of such Shares was originally scheduled to
occur to the Delayed Closing Date, and (ii) the Stockholder shall remain bound
by the restrictions on Transfer contained herein during such delay; provided,
that the Company shall not be required to issue a promissory note to evidence
its payment obligation to the extent such issuance is prohibited by the terms of
any such financing agreements.

          8. PAYMENT FOR SHARES. At any closing held to consummate any
repurchase of the Shares hereunder, the Stockholder shall deliver to the Company
the stock certificates representing such Shares, duly endorsed in blank or with
duly executed stock powers attached, and the Company shall deliver to the
Stockholder a check in the amount of the repurchase price or a promissory note
as provided in Section 7.1.

          9. ADJUSTMENT OF REPURCHASE PRICE. Upon any stock split, reverse stock
split, recombination of shares or other similar reorganization of the capital
structure of the Company, the repurchase price otherwise payable to the
Stockholder upon the repurchase of any Shares pursuant to Section 3 hereof shall
be proportionally adjusted to reflect such reorganization.
