          3. REPURCHASE OF SHARES.

          3.1. VESTING OF SHARES. On and after the date hereof, the terms of any
repurchase of any Shares shall differ depending on whether such Shares are
"Unvested Shares" or "Vested Shares". Initially, 25% of the Shares shall be
considered "Vested Shares" and all other Shares shall be considered "Unvested
Shares". On each anniversary of September 24, 2004 prior to the Termination of
Employment, commencing with September 24, 2005, 25% of the original number of
Shares shall become "Vested Shares", such that all of the Shares shall be Vested
Shares as of and after September 24, 2007 if the Termination of Employment does
not occur prior to such date. If a Target Disposition Event or a Public Sale
occurs prior to a Termination of Employment (the first such event or sale, a
"Vesting Acceleration Event"), (a) 50% of the then Unvested Shares shall become
Vested Shares upon the occurrence of such Vesting Acceleration Event (the
Unvested Shares that become vested upon the occurrence of such Vesting
Acceleration Event shall consist of the Unvested Shares that were scheduled to
vest first chronologically following such Vested Acceleration Event) and (b) the
remaining 50% of the then Unvested Shares shall become Vested Shares on the
earlier of (i) the date that such Unvested Shares are scheduled to vest under
this Agreement and (ii) the first anniversary date of the occurrence of such
Vesting Acceleration Event (such earlier date, the "Final Vesting Date"),
provided that a Termination of Employment has not occurred for Cause or by
resignation on or prior to the Final Vesting Date. Except pursuant to clause (b)
of the immediately preceding

                                       -5-

<PAGE>

sentence, no Shares which have not already become Vested Shares shall become
Vested Shares upon or after the Termination of Employment for any reason.

          3.2. REPURCHASE RIGHTS OF THE COMPANY. Upon the Termination of
Employment at any time and for any reason, the Company shall have the right to
repurchase from the Stockholder, and the Stockholder will at the request of the
Company sell to the Company all (but not less than all) of the Shares at a
purchase price per Share determined pursuant to paragraphs (a) and (b) below:

               (a) in the event that such Termination of Employment is a result
          of the Stockholder's resignation (other than for Good Reason) prior to
          the third anniversary of the date hereof, at a purchase price per
          Share equal to the Original Price Per Share plus interest on such
          amount from the date hereof to the date of repurchase at the rate of
          5% per annum; and

               (b) otherwise, (i) at a purchase price per Vested Share equal to
          the Market Value Per Share and (ii) at a purchase price per Unvested
          Share equal to the Original Price Per Share plus interest on such
          amount from the date hereof to the date of repurchase at the rate of
          5% per annum.

          3.3. REPURCHASE CLOSING. The Company's repurchase rights under Section
3.2 shall be exercisable at any time within ninety (90) days following the
Termination of Employment by notice 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 Termination of Employment is the result of the
Stockholder's resignation (other than for Good Reason) prior to the third
anniversary of the date hereof or (b) otherwise, not earlier than five (5) days
nor later than thirty (30) days after determination of the Common Equity Value
pursuant to Section 3.4. The Company's repurchase rights under Section 3.2 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. Amounts due from the Company to the Stockholder under this Section 3.3
shall be set off in payment of any amounts payable from the Stockholder to the
Company under the Note. Upon delivery by the Company of the repurchase price for
the Shares being repurchased hereunder in 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 3.3, 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.

          3.4. 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 3.2(b) hereof, the Stockholder shall select three (3)
Independent Appraisers that the Stockholder purposes 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,

                                       -6-

<PAGE>

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 3.4 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 3.4 shall be final, conclusive and binding upon the parties.

          4. RESTRICTIONS ON TRANSFER. The Stockholder may not sell, assign,
transfer, pledge or otherwise dispose of ("Transfer") any of the Unvested
Shares, either voluntarily or involuntarily or by operation of law, except to
the Company or any of its Subsidiaries. Except as otherwise expressly provided
in the Stockholder Agreement, the Stockholder may not Transfer any of the Vested
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 that constitute Vested Shares at such time and to any Shares
that become Vested Shares after such time pursuant to the terms hereof. 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 that constitute Vested Shares at such time and to any Shares that become
Vested Shares after such time pursuant to the terms hereof. Under no
circumstances may the Stockholder Transfer any Shares in violation of the terms
of the Note. 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 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

                                       -7-

<PAGE>

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 SEPTEMBER 24, 2004, 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 repurchase price for any Shares
to be repurchased hereunder exceeds amounts owed under the Note so that after
setting off payments due to the Stockholder hereunder against such amounts, the
Company remains obligated to make payments to the Stockholder hereunder, and the
terms of any of the financing agreements of the Company or its Subsidiaries with
their lenders prohibit the Company from making such payments in cash, the
Company shall be entitled to complete the repurchase of such Shares by
delivering to the Stockholder (or any transferee) a promissory note for that
portion of such payment which exceeds any amounts already set off against the
Note. Each such promissory note shall (i) bear interest at the rate of five
percent (5%) per annum, (ii) provide for the payment of the principal evidenced
thereby in such installments and at such times as are permitted under the terms
of the Company's and its Subsidiaries' financing agreements with their lenders,
(iii) be subordinated to the indebtedness of the Company and its Subsidiaries to
their lenders on terms satisfactory to

                                       -8-

<PAGE>

such lenders and (iv) subject to such payment restrictions and 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 (i) offset the
repurchase price for such Shares against any amounts owed by the Stockholder to
the Company under the Note and (ii) deliver to the Stockholder a check in the
amount of any remaining balance 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.

          10. GENERAL.

Shares that were scheduled to vest first chronologically following such Vested
Acceleration Event) and (b) the remaining 50% of the then Unvested Shares shall

          3.2. REPURCHASE BIGHTS OF THE COMPANY. Upon the Termination of
Employment at any time and for any reason, the Company shall have the right to
repurchase from the Stockholder, and the Stockholder will at the request of the
Company sell to the Company all (but not less than all) of the Shares at a
purchase price per Share determined pursuant to paragraphs (a) and (b) below:

               (a) in the event that such Termination of Employment is for Cause
          at any time, or is a result of the Stockholder's resignation (other
          than for Good Reason) prior to the fourth anniversary of the date
          hereof, at a purchase price per Share equal to the Original Price Per
          Share plus interest on such amount from the date hereof to the date of
          repurchase at the rate of 5% per annum; and

               (b) otherwise, (i) at a purchase price per Vested Share equal to
          the Market Value Per Share and (ii) at a purchase price per Unvested
          Share equal to the Original Price Per Share plus interest on such
          amount from the date hereof to the date of repurchase at the rate of
          5% per annum.

          3.3. REPURCHASE CLOSING. The Company's repurchase rights under Section
3.2 shall be exercisable at any time within ninety (90) days following the
Termination of Employment by notice 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 Termination of Employment is for Cause or is the
result of the Stockholder's resignation (other than for Good Reason) prior to
the fourth anniversary of the date hereof or (b) otherwise, not earlier than
five (5) days nor later than thirty (30) days after determination of the Common
Equity Value pursuant to Section 3.4. The Company's repurchase rights under
Section 3.2 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. Amounts due-from the Company to the Stockholder
under this Section 3.3 shall be set off in payment of any amounts payable from
the Stockholder to the Company under the Note. Upon delivery by the Company of
the repurchase price for the Shares being repurchased hereunder in 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 3.3,
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.

          3.4. 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 3.2(b) hereof, the Stockholder shall select three (3)
Independent Appraisers that the Stockholder purposes 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

                                       -6-

<PAGE>

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 3.4 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 3.4 shall be final, conclusive and binding upon the parties.

          4. RESTRICTIONS ON TRANSFER. The Stockholder may not sell, assign,
transfer, pledge or otherwise dispose of ("Transfer") any of the Unvested
Shares, either voluntarily or involuntarily or by operation of law, except to
the Company or any of its Subsidiaries. Except as otherwise expressly provided
in the Stockholder Agreement, the Stockholder may not Transfer any of the Vested
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 that constitute Vested Shares at such time and to any Shares
that become Vested Shares after such time pursuant to the terms hereof. 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 that constitute Vested Shares at such time and to any Shares that become
Vested Shares after such time pursuant to the terms hereof. Under no
circumstances may the Stockholder Transfer any Shares in violation of the terms
of the Note. 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 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.

                                       -7-

          (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 SEPTEMBER 24, 2004, 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 repurchase price for any Shares
to be repurchased hereunder exceeds amounts owed under the Note so that after
setting off payments due to the Stockholder hereunder against such amounts, the
Company remains obligated to make payments to the Stockholder hereunder, and the
terms of any of the financing agreements of the Company or its Subsidiaries with
their lenders prohibit the Company from making such payments in cash, the
Company shall be entitled to complete the repurchase of such Shares by
delivering to the Stockholder (or any transferee) a promissory note for that
portion of such payment which exceeds any amounts already set off against the
Note. Each such promissory note shall (i) bear interest at the rate of five
percent (5%) per annum, (ii) provide for the payment of the principal evidenced
thereby in such installments and at such times as are permitted under the terms
of the Company's and its Subsidiaries' financing agreements with their lenders,
(iii) be subordinated to the indebtedness of the Company and its Subsidiaries to
their lenders on terms satisfactory to such lenders and (iv) subject to such
payment restrictions and 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.

                                       -8-

          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 (i) offset the
repurchase price for such Shares against any amounts owed by the Stockholder to
the Company under the Note and (ii) deliver to the Stockholder a check in the
amount of any remaining balance 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.

          10. GENERAL.

exercising any right, power or privilege hereunder shall impair such right,
power or privilege, nor shall any single or partial exercise of any such right,
power or privilege preclude any further exercise thereof or the exercise of any
other right, power or privilege.

          10.5. COUNTERPARTS. This Agreement may be executed in multiple
counterparts (including by facsimile), each of which shall be deemed an

by the Stockholder without the Company's prior written consent thereto.

understanding of the parties, supersedes all prior agreements and understandings
relating to the subject matter hereof and shall not be amended except by a
written instrument hereafter signed by each of the parties hereto. Nothing in

continuing employment with the Company or any Subsidiary or to restrict in any
way the right to terminate the Stockholder's employment at any time.
