Line Loans at any one time outstanding shall not exceed the Swing Line Commitment.

     Section 2.2 Advance Options. The Revolving Loans shall be constituted of LIBOR
Advances and/or Base Rate Advances, as shall be selected by the Borrower, except as otherwise
provided herein. Any combination of types of Advances may be outstanding at the same time, except
that the total number of outstanding LIBOR Advances shall not exceed eight (8) at any one time.
Each LIBOR Advance shall be in a minimum amount of $500,000. Each Base Rate Advance shall be in a
minimum amount of $100,000. Swing Line Loans may be in any amount requested by the Borrower.

     Section 2.3 Borrowing Procedures.

(a) Request by Borrower. Any request by the Borrower for a Loan shall be in
writing, or by telephone promptly confirmed in writing, and must be given so as to be
received by the Agent not later than:

(i) 1:00 p.m., Minneapolis time, one Business day prior to the date of the requested
Loan, if the Loan shall be comprised of Base Rate Advances; or

(ii) 12:00 noon, Minneapolis time, three Business days prior to the date of the
requested Revolving Loan, if the Revolving Loan shall be, or shall include, a LIBOR
Advance.

12

 

Each request for a Loan shall specify (1) the borrowing date (which shall be a Business
Day), (2) the amount of such Loan and the type or types of Advances comprising such Loan,
and (3) if such Loan shall include LIBOR Advances, the initial Interest Periods for such
Advances. The Swing Line Bank and the Borrower shall, from time to time, enter into
mutually acceptable arrangements for notices of funding, funding and repayment of the Swing
Line Loans.

(b) Funding of Agent. The Agent shall promptly notify each other Bank of the
receipt of such request, the matters specified therein, and of such Bank’s Percentage of the
requested Revolving Loans. On the date of the requested Revolving Loans, each Bank shall
provide its share of the requested Revolving Loans to the Agent in immediately available
funds not later than 11:00 a.m., Minneapolis time. On the date of any requested Swing Line
Loans, the Swing Line Bank shall provide the requested Swing Line Loan to the Agent in
immediately available funds not later than 4:00 p.m., Minneapolis time. Unless the Agent
determines that any applicable condition specified in Article VI has not been
satisfied, the Agent will make the requested Loans available to the Borrower at the Agent’s
principal office in Minneapolis, Minnesota in immediately available funds not later than
5:00 p.m. (Minneapolis time) on the lending date so requested. If the Agent has made a
Revolving Loan to the Borrower on behalf of a Bank but has not received the amount of such
Revolving Loan from such Bank by the time herein required, such Bank shall pay interest to
the Agent on the amount so advanced at the overnight Federal Funds rate from the date of
such Revolving Loan to the date funds are received by the Agent from such Bank, such
interest to be payable with such remittance from such Bank of the principal amount of such
Revolving Loan (provided, however, that the Agent shall not make any Revolving Loan on
behalf of a Bank if the Agent has received prior notice from such Bank that it will not make
such Revolving Loan). If the Agent does not receive payment from such Bank by the next
Business Day after the date of any Revolving Loan, the Agent shall be entitled to recover
such Revolving Loan, with interest thereon at the rate then applicable to the such Revolving
Loan, on demand, from the Borrower, without prejudice to the Agent’s and the Borrower’s
rights against such Bank. If such Bank pays the Agent the amount herein required with
interest at the overnight rate before the Agent has recovered from the Borrower, such Bank
shall be entitled to the interest payable by the Borrower with respect to the Revolving Loan
in question accruing from the date the Agent made such Revolving Loan.

     2.4 Continuation or Conversion of Loans. The Borrower may elect to (i) continue any
outstanding LIBOR Advance from one Interest Period into a subsequent Interest Period to begin on
the last day of the earlier Interest Period, or (ii) convert any outstanding Advance into another
type of Advance (on the last day of an Interest Period only, in the instance of a LIBOR Advance),
by giving the Agent notice in writing, or by telephone promptly confirmed in writing, given so as
to be received by the Agent not later than:

13

 

(a) 1:00 p.m., Minneapolis time, one Business day prior to the date of the requested
continuation or conversion, if the continuing or converted Advance shall be a Base Rate
Advance; or

(b) 12:00 noon, Minneapolis time, three Business days prior to the date of the requested
continuation or conversion, if the continuing or converted Advance shall be a LIBOR Advance.

Each notice of continuation or conversion of an Advance shall specify (i) the effective date of the
continuation or conversion date (which shall be a Business Day), (ii) the amount and the type or
types of Advances following such continuation or conversion (subject to the limitation on amount
set forth in Section 2.2), and (iii) for continuation as, or conversion into, LIBOR
Advances, the Interest Periods for such Advances. Absent timely notice of continuation or
conversion, following expiration of an Interest Period unless the LIBOR Advance is paid in full the
Agent may at any time thereafter convert the LIBOR Advance into a Base Rate Advance. Until such
time as such Advance is converted into a Base Rate Advance by the Agent or the Borrower or is
continued as a LIBOR Advance with a new Interest Period by notice by the Borrower as provided
above, such Advance shall continue to accrue interest at a rate equal to the interest rate
applicable during the expired Interest Period adjusted, however, to reflect changes in the
Applicable Margin. No Advance shall be continued as, or converted into, a LIBOR Advance if the
shortest Interest Period for such Advance may not transpire prior to the Termination Date or if a
Default or Event of Default shall exist.

     Section 2.5 The Notes. The Loans shall be evidenced by the following Notes:

(a) The Revolving Loans of each Bank shall be evidenced by a Revolving Note in the amount
of such Bank’s Commitment originally in effect and dated as of the date of this Agreement.
The Banks shall enter in their respective records the amount of each Revolving Loan and
Advance, the rate of interest borne by each Advance and the payments made on the Revolving
Loans, and such records shall be deemed conclusive evidence of the subject matter thereof,
absent manifest error.

(b) The Swing Line Loans shall be evidenced by the Swing Line Note in the amount of the
Swing Line Commitment. The Swing Line Bank shall enter in its records the amount of each
Swing Line Loan and the payments made on the Swing Line Loans, and such records shall be
deemed conclusive evidence of the subject matter thereof, absent manifest error.

     Section 2.6 Funding Losses. In the event of (a) any failure of the Borrower to
borrow, continue or convert a LIBOR Advance on a date specified in a notice thereof, or (b) any
payment (including, without limitation, any payment pursuant to Section 4.2, 4.3 or
10.2), prepayment or conversion of any LIBOR Advance on a date other than the last day of
the Interest Period for such Advance, the Borrower agrees to pay each Bank’s costs, expenses and
Interest Differential (as determined by such Bank) incurred as a result of such event. The term
“Interest Differential”

14

 

shall mean that sum amount, not less than $0, equal to the financial loss incurred by each Bank
resulting from such event, calculated as the difference between the amount of interest such Bank
would have earned (from like investments in the Money Markets as of the first day of the Interest
Period of the relevant Advance) had such event not occurred and the interest the Bank will actually
earn (from like investments in the Money Markets as of the date of such event) as a result of the
redeployment of funds from such event. Because of the short-term nature of this facility, the
Borrower agrees that the Interest Differential shall not be discounted to its present value. The
term “Money Markets” refers to one or more wholesale funding markets available to the Banks,
including negotiable certificates of deposit, commercial paper, LIBOR deposits, bank notes, federal
funds and others. Such determinations by each Bank of shall be conclusive in the absence of
manifest error.

     Section 2.7 Refunding of Swing Line Loans.

(a) At any time permitted hereunder, the Borrower may request the Banks to make Revolving
Loans which may be applied to repay the Swing Line Loans outstanding. Upon occurrence and
during continuance of a Default or Event of Default, the Swing Line Bank may, on behalf of
the Borrower (which hereby irrevocably directs the Swing Line Bank to act on its behalf),
upon notice given by the Swing Line Bank no later than 12:00 noon, Minneapolis time, on the
relevant refunding date, request each Bank to make, and each Bank hereby agrees to make, a
Revolving Loan (which shall be a Base Rate Advance), in an amount equal to such Bank’s
Percentage of the aggregate amount of the Swing Line Loans (the “Refunded Swing Line Loans”)
outstanding on the date of such notice, to refund such Swing Line Loans. Each Bank shall
make the amount of such Revolving Loan available to the Agent in immediately available
funds, no later than 2:00 p.m., Minneapolis time, on the date of such notice. The proceeds
of such Revolving Loans shall be distributed by the Agent to the Swing Line Bank and
immediately applied by the Swing Line Bank to repay the Refunded Swing Line Loans.

(b) If, for any reason, Revolving Loans may not be (as determined by the Agent in its sole
discretion), or are not, made pursuant to Section 2.7(a) to repay Swing Line Loans,
then, effective on the date such Revolving Loans would otherwise have been made, each Bank
severally, unconditionally and irrevocably agrees that it shall purchase a participating
interest in such Swing Line Loans (“Unrefunded Swing Line Loans”) in an amount equal to the
amount of Revolving Loans which would otherwise have been made by such Bank pursuant to
Section 2.7(a). Each Bank will immediately transfer to the Agent, in immediately
available funds, the amount of its participation (the “Swing Line Participation Amount”),
and the proceeds of such participation shall be distributed by the Agent to the Swing Line
Bank in such amount as will reduce the amount of the participating interest retained by the
Swing Line Bank in its Swing Line Loans.

(c) Whenever, at any time after the Swing Line Bank has received from any Bank such Bank’s
Swing Line Participation Amount, the Swing Line Bank receives any payment on account of the
Swing Line Loans, the Swing Line Bank will distribute to such Bank its

15

 

Swing Line Participation Amount (appropriately adjusted, in the case of interest payments,
to reflect the period of time during which such Bank’s participating interest was
outstanding and funded and, in the case of principal and interest payments, to reflect such
Bank’s pro rata portion of such payment if such payment is not sufficient to
pay the principal of and interest on all Swing Line Loans then due); provided,
however, that in the event that such payment received by the Swing Line Bank is
required to be returned, such Bank will return to the Swing Line Bank any portion thereof
previously distributed to it by the Swing Line Bank.

(d) Each Bank’s obligation to make the Loans referred to in Section 2.7(a) and to
purchase participating interests pursuant to Section 2.7(b) shall be absolute and
unconditional and shall not be affected by any circumstance, including, without limitation,
(i) any setoff, counterclaim, recoupment, defense or other right which such Bank or the
Borrower may have against the Swing Line Bank, the Borrower or any other Person for any
reason whatsoever; (ii) the occurrence or continuance of a Default or an Event of Default or
the failure to satisfy any of the other conditions precedent specified in Article
VI; (iii) any adverse change in the condition (financial or otherwise) of the Borrower;
(iv) any breach of this Agreement or any other Loan Document by the Borrower or any Bank; or
(v) any other circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing.

     Section 2.8 Letters of Credit

(a) Letters of Credit. Subject to the terms and conditions of this Agreement, and
on the condition that aggregate Letter of Credit Obligations shall never exceed the lesser
of (i) $30,000,000 or (ii) the Commitments, and that the sum of Letter of Credit Obligations
plus Loans shall never exceed the aggregate Commitments of all Banks, the Borrower may, in
addition to Loans, request that the Agent issue letters of credit for the account of the
Borrower or any Subsidiary, as provided in Section 2.8(f), by making such request to
the Agent (such letters of credit as any of them may be amended, supplemented, extended or
confirmed from time to time, being herein collectively called the “Letters of Credit”). The
Agent may, at its discretion, elect to issue or decline to issue any requested Letter of
Credit. No Letter of Credit shall expire more than one year after the date of issuance
thereof (provided, that Letters of Credit may automatically extend absent notice of
termination by the issuer). Upon the date of the issuance of a Letter of Credit, the Agent
shall be deemed, without further action by any party hereto, to have sold to each Bank, and
each Bank shall be deemed without further action by any party hereto, to have purchased from
the Agent, a participation, in its Percentage, in such Letter of Credit and the related
Letter of Credit Obligations.

(b) Purchase Unconditional. Each Bank’s purchase of a participating interest in a
Letter of Credit pursuant to Section 2.8(a) shall be absolute and unconditional and
shall not be affected by any circumstance, including, without limitation, (i) any setoff,
counterclaim, recoupment, defense or other right which such Bank or the Borrower may have
against

16

 

the Agent, the Borrower or any other Person for any reason whatsoever; (ii) the occurrence
or continuance of a Default or an Event of Default or the failure to satisfy any of the
other conditions precedent in Article VI; (iii) any adverse change in the condition
(financial or otherwise) of the Borrower; (iv) any breach of this Agreement or any other
Loan Document by the Borrower or any Bank; (v) the expiry date of any Letter of Credit
occurring after such Bank’s Commitment has terminated; or (vi) any other circumstance,
happening or event whatsoever, whether or not similar or any of the foregoing.

(c) Additional Provisions. The following additional provisions shall apply to each
Letter of Credit:

(i) Upon receipt of any request for a Letter of Credit, the Agent shall notify each
Bank of the contents of such request and of such Bank’s Percentage of the amount of
such proposed Letter of Credit.

(ii) No Letter of Credit may be issued if after giving effect thereto the Letter of
Credit Obligations shall exceed $30,000,000 or if the sum of (A) the aggregate
outstanding principal amount of Loans plus (B) the aggregate Letter of
Credit Obligations would exceed the aggregate Commitments of all Banks. The
Commitment of each Bank shall be deemed to be utilized for all purposes hereof in an
amount equal to such Bank’s Percentage of the Letter of Credit Obligations.

(iii) Upon receipt from the beneficiary of any Letter of Credit of any demand for
payment thereunder, Agent shall promptly notify the Borrower and each Bank as to the
amount to be paid as a result of such demand and the payment date. If at any time
the Agent shall have made a payment to a beneficiary of such Letter of Credit in
respect of a drawing or in respect of an acceptance created in connection with a
drawing under such Letter of Credit, each Bank will pay to Agent immediately upon
demand by the Agent at any time during the period commencing after such payment
until reimbursement thereof in full by the Borrower, an amount equal to such Bank’s
Percentage of such payment, together with interest on such amount for each day from
the date of demand for such payment (or, if such demand is made after 2:00 p.m.
Minneapolis time on such date, from the next succeeding Business Day) to the date of
payment by such Bank of such amount at a rate of interest per annum equal to the
Federal Funds Effective Rate for such period.

(iv) The Borrower shall be irrevocably and unconditionally obligated forthwith to
reimburse the Agent for any amount paid by the Agent upon any drawing under any
Letter of Credit, without presentment, demand, protest or other formalities of any
kind, all of which are hereby waived. Such reimbursement may, subject to
satisfaction of the conditions in Article VI hereof and to the available
Commitment (after adjustment in the same to reflect the elimination of the
corresponding Letter of Credit Obligation), be made by the borrowing of Loans.

17

 

The Agent will pay to each Bank such Bank’s Percentage of all amounts received from
the Borrower for application in payment, in whole or in part, of a Letter of Credit
Obligation, but only to the extent such Bank has made payment to the Agent in
respect of such Letter of Credit pursuant to clause (iii) above.

(v) The Borrower’s obligation to reimburse the Agent for any amount paid by the
Agent upon any drawing under any Letter of Credit shall be performed strictly in
accordance with the terms of this Agreement and the applicable Letter of Credit
Agreement under any and all circumstances whatsoever and irrespective of (A) any
lack of validity or enforceability of any Letter of Credit, any Letter of Credit
Agreement or this Agreement, or any term or provision therein, (B) any draft or
other document presented under a Letter of Credit proving to be forged, fraudulent,
or invalid in any respect or any statement therein being untrue or inaccurate in any
respect, (C) payment by the Agent under a Letter of Credit against presentation of a
draft or other document that does not comply with the terms of such Letter of
Credit, or (D) any other event or circumstance whatsoever, whether or not similar to
any of the foregoing, that might, but for the provisions of this clause (v),
constitute a legal or equitable discharge of, or provide a right of setoff against,
the Borrower’s obligations hereunder. Neither the Agent nor the Bank shall have any
liability or responsibility by reason of or in connection with the issuance or
transfer of any Letter of Credit or any payment or failure to make any payment
thereunder (irrespective of any of the circumstances referred to in the preceding
sentence), or any error, omission, interruption, loss or delay in transmission or
delivery of any draft, notice or other communication under or relating to any Letter
of Credit (including any document required to make a drawing thereunder), any error
in interpretation of technical terms or any consequence arising from causes beyond
the control of the Agent; provided that the foregoing shall not be construed to
excuse the Agent from liability to the Borrower to the extent of any direct damages
(as opposed to consequential damages, claims in respect of which are hereby waived
by the Borrower to the extent permitted by applicable law) suffered by the Borrower
that are caused by the Agent’s failure to exercise care when determining whether
drafts and other documents presented under a Letter of Credit comply with the terms
thereof. The parties hereto expressly agree that, in the absence of gross
negligence or willful misconduct on the part of the Agent (as finally determined by
a court of competent jurisdiction), the Agent shall be deemed to have exercised care
in each such determination. In furtherance of the foregoing and without limiting
the generality thereof, the parties hereto expressly agree that, with respect to
documents presented which appear on their face to be in substantial compliance with
the terms of the Letter of Credit, the Agreement may, in its sole discretion, either
accept and make payment upon such documents without responsibility for further
investigation or refuse to accept and make payment upon such documents if such
documents are not in strict compliance with the terms of such Letter of Credit.

18

 

(vi) The Borrower will pay to Agent for the account of each Bank in accordance with
its Percentage letter of credit fee with respect to each Letter of Credit equal to
an amount, calculated on the basis of face amount of each Letter of Credit, in each
case for the period from and including the date of issuance of such Letter of Credit
to and including the date of expiration or termination thereof at a per annum rate
equal to the then-applicable Applicable Margin for LIBOR Advances, such fee to be
due and payable quarterly, in arrears on the Payment Dates. The Agent will pay to
each Bank, promptly after receiving any payment in respect of letter of credit fee
referred to in this clause (v), an amount equal to the product of such
Bank’s Percentage times the amount of such fees. The Borrower shall also pay
to Agent at the Principal Office for the account of the Agent a fronting fee of
0.125% of the face amount of the applicable Letter of Credit. At all times that the
rate of interest provided in Section 3.1(d) shall apply to the Loans, the
fee paid for the account of the Banks under this Section shall be increased by 2.00%
per annum. All fees hereunder shall be computed on the basis of a year of 360 days
and paid for the actual number of days elapsed.

(vii) The issuance by the Agent of each Letter of Credit shall, in addition to the
discretionary nature of this facility, be subject to the conditions precedent that
the Borrower shall have executed and delivered such applications and other
instruments and agreements relating to such Letter of Credit as the Agent shall have
reasonably requested and are not inconsistent with the terms of this Agreement (the
“Letter of Credit Agreements”). In the event of a conflict between the
terms of this Agreement and the terms of any Letter of Credit Agreement (including
the charging of any fees other than normal and customary reimbursable expenses), the
terms hereof shall control.

(viii) In the event that any Letter of Credit remains outstanding after the
Termination Date, the Borrower shall deliver, prior to the Termination Date, cash
collateral to be held and applied in accordance with the terms of Section
10.3.

(d) Indemnification; Release. Borrower hereby indemnifies and holds harmless the
Agent and each Bank from and against any and all claims and damages, losses, liabilities,
costs or expenses which the Agent or such Bank may incur (or which may be claimed against
the Agent or such Bank by any Person whatsoever), regardless of whether caused in whole or
in part by the negligence of any of the indemnified parties, in connection with the
execution and delivery of any Letter of Credit or transfer of or payment or failure to pay
under any Letter of Credit; provided that the Borrower shall not be required to
indemnify any party seeking indemnification for any claims, damages, losses, liabilities,
costs or expenses to the extent, but only to the extent, caused by (i) the willful
misconduct or gross negligence of the party seeking indemnification, or (ii) by the failure
by the party seeking indemnification to pay under any Letter of Credit after the
presentation to it of a request required to be paid under applicable law.

19

 

(e) Existing Letters of Credit. Certain Letters of Credit previously issued by the
Agent and listed on Schedule 2.6 shall be deemed to be “Letters of Credit” for all purposes
hereunder.

(f) Issuance of Letters of Credit for Account of Subsidiaries. Upon request of the
Borrower, Letters of Credit may be issued for the account of Subsidiaries of the Borrower.
In such event, the Borrower shall be deemed to have irrevocably guarantied payment of the
obligations of each Subsidiary in respect of Letters of Credit issued for the account of
such Subsidiary, and if requested by the Bank, the Borrower shall, together with such
Subsidiary, enter into the Letter of Credit Agreement as co-applicant or guarantor, and
shall execute and deliver such other instrument of guaranty as shall be required by the
Agent.

     Section 2.9 Purpose of the Loans. The Loans shall be used (a) to refinance certain
indebtedness of the Borrower, and (b) for purposes of funding working capital, capital
expenditures, and other corporate purposes of the Borrower and its Subsidiaries.

ARTICLE III INTEREST AND FEES

     Section 3.1 Interest.

(a) LIBOR Advances. The unpaid principal amount of each LIBOR Advance shall bear
interest prior to maturity at a rate per annum equal to the LIBOR Rate (Reserve Adjusted) in
effect for each Interest Period for such LIBOR Advance plus the Applicable Margin per annum.

(b) Base Rate Advances. The unpaid principal amount of each Base Rate Advance shall
bear interest prior to maturity at a rate per annum equal to the Base Rate plus the
Applicable Margin per annum.

(c) Swing Line Loans. The unpaid principal amount of all Swing Line Loans shall
bear interest prior to maturity at a rate per annum equal to the LIBOR Rate (Reserve
Adjusted) Daily Floating plus the Applicable Margin for LIBOR Advances per annum.

(d) Interest After Maturity. Any amount of the Loans not paid when due, whether at
the date scheduled therefor or earlier upon acceleration, shall bear interest until paid in
full at a rate per annum equal to the greater of (i) 2.00% in excess of the rate applicable
to the unpaid principal amount immediately before it became due, or (ii) 2.00% in excess of
the Base Rate in effect from time to time.

     Section 3.2 Commitment Fee. The Borrower shall pay fees (the “Commitment Fees”) to
the Agent for the account of the Banks (in according with their respective Percentages) in an

20

 

amount determined by applying the Applicable Commitment Fee Rate per annum to the average daily

interest thereon, shall be due and payable on the Termination Date.

     Section 4.2 Optional Prepayments. The Borrower may, upon at least three (3) Business
Days’ prior written or telephonic notice received by the Bank, prepay the Loans, in whole or in
part, at any time subject to the provisions of Section 2.6, without any other premium or
penalty. Any such prepayment must be accompanied by accrued and unpaid interest on the amount

Any prepayment of a LIBOR Advance shall be in an amount equal to the remaining entire principal
balance of such Advance.

any time, upon no less than 2 Business Days prior written or telephonic notice received by the
Agent, reduce the Commitment, with any such reduction in a minimum amount of $500,000 or an
integral multiple thereof. Upon any reduction in the Commitment pursuant to this Section, the
Borrower shall pay to the Agent for the account of the Banks the amount, if any, by which the
aggregate unpaid principal amount of outstanding Loans plus the Letter of Credit Obligations
exceeds the Commitment as so reduced. Amounts so paid cannot be reborrowed. The Borrower may, at
any time, upon not less than 2 Business Days prior written notice to the Agent, terminate the
Commitment in its entirety. Upon termination of the Commitment pursuant to this Section, the
Borrower shall pay to the Agent for the account of the Banks the full amount of all outstanding

Notwithstanding the foregoing, the Commitment may not be reduced to an amount below outstanding
Letter of Credit Obligations, or terminated if Letters of Credit are outstanding

21

 

     Section 4.4 Payments. Payments and prepayments of principal of, and interest on, the
Notes and all fees, expenses and other obligations under the Loan Documents shall be made without
set-off or counterclaim in immediately available funds not later than 2:00 p.m., Minneapolis time,
on the dates due at the main office of the Agent in Minneapolis, Minnesota, provided,
however, that the Swing Line Bank and the Borrower shall enter into mutually acceptable
arrangements for payment of the Swing Line Loans which may permit payment of the Swing Line Loans
later than such time. Funds received on any day after such time shall be deemed to have been
received on the next Business Day. The Agent shall promptly distribute in like funds to each Bank
its Percentage share of each such payment of principal, interest and Commitment Fees. Subject to
the definition of the term “Interest Period”, whenever any payment to be made hereunder or on the
Notes shall be stated to be due on a day which is not a Business Day, such payment shall be made on
the next succeeding Business Day and such extension of time shall be included in the computation of
any interest or fees. The Agent is authorized to debit the operating account of the Borrower
designated by the Borrower for such purpose from time to time for all payments when due hereunder
(provided that if such account shall not have sufficient available funds to pay interest when due,
the Borrower shall pay such interest in immediately available funds).

     Section 4.5 Proration of Payments. If any Bank or other holder of a Loan shall
obtain any payment or other recovery (whether voluntary, involuntary, by application of offset,
pursuant to the guaranty hereunder, or otherwise) on account of principal of, interest on, or fees
with respect to any Loan, or payment of any Letter of Credit Obligations, in any case in excess of
the share of payments and other recoveries of other Banks or holders, such Bank or other holder
shall purchase from the other Banks or holders, in a manner to be specified by the Agent, such
participations in the Loans held by such other Banks or holders as shall be necessary to cause such
purchasing Bank or other holder to share the excess payment or other recovery ratably with each of
such other Banks or holders; provided, however, that if all or any portion of the
excess payment or other recovery is thereafter recovered from such purchasing Bank or holder, the
purchase shall be rescinded and the purchase price restored to the extent of such recovery, but
without interest.

ARTICLE V ADDITIONAL PROVISIONS RELATING TO LOANS

     Section 5.1 Increased Costs. If, as a result of any law, rule, regulation, treaty or
directive, or any change therein or in the interpretation or administration thereof, or compliance
by the Banks with any request or directive (whether or not having the force of law) from any court,
central bank, governmental authority, agency or instrumentality, or comparable agency:

(a) any tax, duty or other charge with respect to any Loan, the Notes or the Commitments is
imposed, modified or deemed applicable, or the basis of taxation of payments to any Bank of
interest or principal of the Loans or of the Commitment Fees (other than taxes imposed on
the overall net income of such Bank by the jurisdiction in which such Bank has its principal
office) is changed;

22

 

(b) any reserve, special deposit, special assessment or similar requirement against assets
of, deposits with or for the account of, or credit extended by, any Bank is imposed,
modified or deemed applicable;

(c) any increase in the amount of capital required or expected to be maintained by any Bank
or any Person controlling such Bank is imposed, modified or deemed applicable; or

(d) any other condition affecting this Agreement or the Commitments is imposed on any Bank
or the relevant funding markets;

and such Bank determines that, by reason thereof, the cost to such Bank of making or maintaining
the Loans, issuing or participating in the Letters of Credit or extending its Commitment is
increased, or the amount of any sum receivable by such Bank hereunder or under the Notes in respect
of any Loan is reduced;

then, the Borrower shall pay to such Bank upon demand such additional amount or amounts as
will compensate such Bank (or the controlling Person in the instance of (c) above) for such
additional costs or reduction (provided that the Banks have not been compensated for such
additional cost or reduction in the calculation of the LIBOR Reserve Rate). Any Bank making such
demand shall inform the Borrower of the basis for such demand, and provide a statement showing, in
reasonable detail, calculation of the amount demanded. The Borrower will promptly notify such Bank
if the Borrower does not agree to such Bank’s determination of any such amount. Any Bank’s
reasonable determination of such amount shall be presumed correct, absent its manifest error or
negligence in determining such amounts. In determining such amounts, the Banks may use any
reasonable averaging, attribution and allocation methods. Notwithstanding the foregoing, no Bank
shall charge the Borrower for additional amounts for such additional costs or reductions that
applied or accrued more than 90 days prior to the time that such Bank became aware of the event
giving rise to such additional costs or reductions.

     Section 5.2 Deposits Unavailable or Interest Rate Unascertainable or Inadequate;
Impracticability. If the Agent determines (which determination shall be conclusive and binding
on the parties hereto) that:

(a) deposits of the necessary amount for the relevant Interest Period for any LIBOR Advance
are not available in the relevant markets or that, by reason of circumstances affecting such
market, adequate and reasonable means do not exist for ascertaining the LIBOR Interbank Rate
for such Interest Period;

(b) the LIBOR Rate (Reserve Adjusted) will not adequately and fairly reflect the cost to the
Banks of making or funding the LIBOR Advance for a relevant Interest Period; or

(c) the making or funding of LIBOR Advances has become impracticable as a result of any
event occurring after the date of this Agreement which, in the opinion of the Agent,

23

 

materially and adversely affects such Advances or any Bank’s Commitment or the relevant
market;

the Agent shall promptly give notice of such determination to the Borrower, and (i) any notice of a
new LIBOR Advance previously given by the Borrower and not yet borrowed or converted shall be
deemed to be a notice to make a Base Rate Advance, and (ii) the Borrower shall be obligated to
either prepay in full any outstanding LIBOR Advances, without premium or penalty on the last day of
the current Interest Period with respect thereto or convert any such LIBOR Advance to a Base Rate
Advance on such last day.

     Section 5.3 Changes in Law Rendering LIBOR Advances Unlawful. If at any time due to
the adoption of any law, rule, regulation, treaty or directive, or any change therein or in the
interpretation or administration thereof by any court, central bank, governmental authority, agency
or instrumentality, or comparable agency charged with the interpretation or administration thereof,
or for any other reason arising subsequent to the date of this Agreement, it shall become unlawful
or impossible for any Bank to make or fund any LIBOR Advance, the obligation of such Bank to
provide such Advance shall, upon the happening of such event, forthwith be suspended for the
duration of such illegality or impossibility. If any such event shall make it unlawful or
impossible for the Bank to continue any LIBOR Advance previously made by it hereunder, such Bank
shall, upon the happening of such event, notify the Agent and the Borrower thereof in writing, and
the Borrower shall, at the time notified by such Bank, either convert each such unlawful Advance to
a Base Rate Advance or repay such Advance in full, together with accrued interest thereon, subject
to the provisions of Section 2.6.

     Section 5.4 Discretion of the Banks as to Manner of Funding. Notwithstanding any
provision of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its
funding of all or any part of the Loans in any manner it elects; it being understood, however, that
for purposes of this Agreement, all determinations hereunder shall be made as if the Banks had
actually funded and maintained each LIBOR Advance during the Interest Period for such Advance
through the purchase of deposits having a term corresponding to such Interest Period and bearing an
interest rate equal to the LIBOR Interbank Rate for such Interest Period (whether or not any Bank
shall have granted any participations in such Advances).

ARTICLE VII REPRESENTATIONS AND WARRANTIES

     To induce the Agent and the Banks to enter into this Agreement, to grant the Commitments and
to make Loans hereunder, the Borrower represents and warrants to the Agent and the Banks:

     Section 7.1 Organization, Standing, Etc. The Borrower and each of its corporate
Material Subsidiaries are corporations duly incorporated and validly existing and in good standing
under the laws of the jurisdiction of their respective incorporation and have all requisite
corporate power and authority to carry on their respective businesses as now conducted, to (in the
instance of the Borrower) enter into the Loan Documents and to perform its obligations under the
Loan Documents. The Borrower and each of the Material Subsidiaries are duly qualified and in good
standing as a foreign corporation in each jurisdiction in which the character of the properties
owned, leased or operated by it or the business conducted by it makes such qualification necessary,
and failure to so qualify or remain in good standing would constitute an Adverse Event.

     Section 7.2 Authorization and Validity. The execution, delivery and performance by
the Borrower of the Loan Documents have been duly authorized by all necessary corporate action by
the Borrower, and the Loan Documents constitute the legal, valid and binding obligations of the
Borrower, enforceable against the Borrower in accordance with their respective terms, subject to
limitations as to enforceability which might result from bankruptcy, insolvency, moratorium and
other similar laws affecting creditors’ rights generally and subject to limitations on the
availability of equitable remedies.

     Section 7.3 No Conflict; No Default. The execution, delivery and performance by the
Borrower of the Loan Documents will not (a) violate any provision of any law, statute, rule or
regulation or any order, writ, judgment, injunction, decree, determination or award of any court,
governmental agency or arbitrator presently in effect having applicability to the Borrower, (b)
violate or contravene any provisions of the Articles (or Certificate) of Incorporation or by-laws
of the Borrower, or (c) result in a breach of or constitute a default under any indenture, loan or
credit agreement or any other agreement, lease or instrument to which the Borrower is a party or by
which it or any of its properties may be bound or result in the creation of any Lien on any asset
of the Borrower or any Material Subsidiary, which in any such case under this subsection (c) would
constitute an Adverse Event. Neither the Borrower nor any Material Subsidiary is in default under
or in violation of any such law, statute, rule or regulation, order, writ, judgment, injunction,
decree, determination or award or any such indenture, loan or credit agreement or other agreement,
lease or instrument in any case in which the consequences of such default or violation could
constitute an Adverse Event. No Default or Event of Default has occurred and is continuing.

     Section 7.4 Government Consent. No order, consent, approval, license, authorization
or validation of, or filing, recording or registration with, or exemption by, any governmental or
public body or authority is required on the part of the Borrower to authorize, or is required in
connection with the execution, delivery and performance of, or the legality, validity, binding
effect or enforceability of, the Loan Documents.

26

 

     Section 7.5 Financial Statements and Condition. The Parent’s audited consolidated
financial statements as of December 31, 2006, and the Borrower’s unaudited quarterly financial
statements as at June 30, 2007, as heretofore furnished to the Banks, have been prepared in
accordance with GAAP on a consistent basis and fairly present the financial condition of the
Parent, the Borrower and the Subsidiaries as at such dates and the results of their operations for
the fiscal year then ended. As of the dates of such consolidated financial statements, neither the
Borrower nor any Material Subsidiary had any material obligation, contingent liability, liability
for taxes or long-term lease obligation which is not reflected in such consolidated financial
statements or in the notes thereto. Since December 31, 2006, no Adverse Event has occurred.

     Section 7.6 Litigation and Contingent Liabilities. Except as described in
Schedule 7.6, there are no actions, suits or proceedings pending or, to the knowledge of
the Borrower, threatened against or affecting the Borrower or any Material Subsidiary or any of
their properties before any court or arbitrator, or any governmental department, board, agency or
other instrumentality which, if determined adversely to the Borrower or such Material Subsidiary,
could constitute an Adverse Event. Except as described in Schedule 7.6, neither the
Borrower nor any Material Subsidiary has any contingent liabilities which are material to the
Borrower and the Subsidiaries as a consolidated enterprise.

     Section 7.7 Compliance. The Borrower and the Material Subsidiaries are in material
compliance with all statutes and governmental rules and regulations applicable to them.

     Section 7.8 Environmental, Health and Safety Laws. To the best of the Borrower’s
knowledge after due inquiry, there does not exist any violation by the Borrower or any Material
Subsidiary of any applicable federal, state or local law, rule or regulation or order of any
government, governmental department, board, agency or other instrumentality relating to
environmental, pollution, health or safety matters which will or threatens to impose a material
liability on the Borrower or a Material Subsidiary or which would require a material expenditure by
the Borrower or such Material Subsidiary to cure. Neither the Borrower nor any Material Subsidiary
has received any notice to the effect that any part of its operations or properties is not in
material compliance with any such law, rule, regulation or order or notice that it or its property
is the subject of any governmental investigation evaluating whether any remedial action is needed
to respond to any release of any toxic or hazardous waste or substance into the environment, the
consequences of which non-compliance or remedial action could constitute an Adverse Event.

     Section 7.9 ERISA. Each Plan complies with all material applicable requirements of
ERISA and the Code and with all material applicable rulings and regulations issued under the
provisions of ERISA and the Code setting forth those requirements. No Reportable Event, other than
a Reportable Event for which the reporting requirements have been waived by regulations of the
PBGC, has occurred and is continuing with respect to any Plan. All of the minimum funding
standards applicable to such Plans have been satisfied and there exists no event or condition which
would permit the institution of proceedings to terminate any Plan under Section 4042 of ERISA.

27

 

The current value of the Plans’ benefits guaranteed under Title IV or ERISA does not exceed the
current value of the Plans’ assets allocable to such benefits.

     Section 7.10 Regulation U. The Borrower is not engaged in the business of extending
credit for the purpose of purchasing or carrying margin stock (as defined in Regulation U of the
Board of Governors of the Federal Reserve System) and no part of the proceeds of any Loan will be
used to purchase or carry margin stock or for any other purpose which would violate any of the
margin requirements of the Board of Governors of the Federal Reserve System.

     Section 7.11 Ownership of Property; Liens. Each of the Borrower and the Material
Subsidiaries has good and marketable title to its real properties and good and sufficient title to
its other properties, including all properties and assets referred to as owned by the Borrower and
the Material Subsidiaries in the audited consolidated financial statement of the Borrower referred
to in Section 7.5 (other than property disposed of since the date of such financial
statement in the ordinary course of business). None of the properties, revenues or assets of the
Borrower or any of the Material Subsidiaries is subject to a Lien, except for (a) Liens disclosed
in the consolidated financial statements referred to in Section 7.5, (b) Liens listed on
Schedule 7.11, or (c) Liens allowed under Section 9.9.

     Section 7.12 Taxes. Each of the Borrower and the Material Subsidiaries has filed all
federal, state and local tax returns required to be filed and has paid or made provision for the
payment of all taxes due and payable pursuant to such returns and pursuant to any assessments made
against it or any of its property and all other taxes, fees and other charges imposed on it or any
of its property by any governmental authority (other than taxes, fees or charges the amount or
validity of which is currently being contested in good faith by appropriate proceedings and with
respect to which reserves in accordance with GAAP have been provided on the books of the Borrower).
No tax Liens have been filed and no material claims are being asserted with respect to any such
taxes, fees or charges. The charges, accruals and reserves on the books of the Borrower in respect
of taxes and other governmental charges are adequate.

     Section 7.13 Trademarks, Patents. Each of the Borrower and the Material Subsidiaries
possesses or has the right, by way of ownership or license, to use all of the patents, trademarks,
trade names, service marks and copyrights, and applications therefor, and all technology, know-how,
processes, methods and designs used in or necessary for the conduct of its business, without known
conflict with the rights of others.

     Section 7.14 Investment Company Act. Neither the Borrower nor any Subsidiary is an
“investment company” or a company “controlled” by an investment company within the meaning of the
Investment Company Act of 1940, as amended.

     Section 7.15 Subsidiaries. Schedule 7.15 sets forth as of the date of this
Agreement a list of all Subsidiaries and the number and percentage of the shares of each class of
capital stock owned beneficially or of record by the Borrower or any Subsidiary therein, and the
jurisdiction of incorporation of each Subsidiary.

28

 

     Section 7.16 Partnerships and Joint Ventures. Schedule 7.16 sets forth as
of the date of this Agreement a list of all partnerships or joint ventures in which the Borrower or
any Subsidiary is a partner (limited or general) or joint venturer.

     Section 7.17 Senior Debt. The Loans are senior unsecured Indebtedness of the
Borrower, and are pari passu and of equal rank and seniority with all senior unsecured Indebtedness
of the Borrower.

each deposit account and all deposit account balances, cash and any other property of the Borrower
now or hereafter maintained with, or in the possession of, the Agent, such Bank or such other
holder of a Note. Upon the occurrence of any Event of Default, upon written direction by the Agent
to such effect, the Agent, each such Bank and each such holder of a Note may: (a) refuse to allow
withdrawals from any such deposit account; (b) apply the amount of such deposit account balances
and the other assets of the Borrower described above to the Obligations; and (c) offset any other
obligation of the Agent, such Bank or such holder of a Note against the Obligations; all whether or
not the Obligations are then due or have been accelerated and all without any advance or
contemporaneous notice or demand of any kind to the Borrower, such notice and demand being
expressly waived.

Exhibit C

Guaranty

GUARANTY

(Joint and Several)

     FOR VALUE RECEIVED and in consideration of entry by the Banks (as defined in the Credit
Agreement) and U.S. BANK NATIONAL ASSOCIATION, as agent for the Banks (in such capacity, together
with it successors and assigns, called the “Agent”) into that certain Credit Agreement, dated as of
October 2, 2007 (as thereafter amended, modified, extended, renewed, restated or replaced from time
to time called the “Credit Agreement”) among the Banks, the Agent and VARISTAR CORPORATION, a
Minnesota corporation (hereinafter called the “Debtor”), the undersigned corporation (the
“Guarantors”) hereby JOINTLY AND SEVERALLY unconditionally guarantee the full and prompt payment
when due, whether by acceleration or otherwise, and at all times thereafter, of all obligations of
the Debtor to the Banks or the Agent under the Credit Agreement, each Note issued thereunder, and
each other Loan Document (as defined therein), including without limitation all future advances,
and all obligations to reimburse the Agent for drawings under all Letters of Credit, and all of
such obligations that arise after the filing of a petition by or against the Debtor under the
Bankruptcy Code, even if the obligations do not accrue because of the automatic stay under
Bankruptcy Code Section 362 or otherwise (all such obligations being hereinafter collectively
called the “Liabilities”), and the Guarantors further jointly and severally agree to pay all
expenses (including attorneys’ fees and legal expenses) paid or incurred by the Banks or Agent in
endeavoring to collect the Liabilities, or any part thereof, and in enforcing this guaranty.

     The Guarantors agree that, in the event of the dissolution or insolvency of the Debtor or any
Guarantor, or the inability of the Debtor or any Guarantor to pay debts as they mature, or an
assignment by the Debtor or any Guarantor for the benefit of creditors, or the institution of any
proceeding by or against the Debtor or the Guarantor alleging that the Debtor or any Guarantor is
insolvent or unable to pay debts as they mature, and if such event shall occur at a time when any
of the Liabilities may not then be due and payable, the Guarantors will pay to the Agent forthwith
the full amount which would be payable hereunder by the Guarantors if all Liabilities were then due
and payable.

     As additional security for the payment of all of the Liabilities and all obligations of the
Guarantors hereunder (collectively, the “Guaranty Obligations”), each Guarantor grants to the Agent
for the benefit of itself and the Banks a security interest in, a lien on, and an express
contractual right to set off against, each deposit account and all deposit account balances, cash
and any other property of such Guarantor now or hereafter maintained with, or in the possession of,
the Agent. Upon the occurrence of any default hereunder (as described in the immediately preceding
paragraph), the Agent may: (a) refuse to allow withdrawals from any such deposit account; (b) apply
the amount of such deposit account balances and the other assets of the Guarantors described above
to the Guaranty Obligations; and (c) offset any other obligation of the Agent against the Guaranty
Obligations; all whether or not the Guaranty Obligations are then due or have been accelerated and

13

 

all without any advance or contemporaneous notice or demand of any kind to the Guarantor, such
notice and demand being expressly waived.

     This guaranty shall in all respects be a continuing, absolute and unconditional guaranty, and
shall remain in full force and effect (notwithstanding, without limitation, the dissolution of any
Guarantor or that at any time or from time to time all Liabilities may have been paid in full).

     The Guarantors further agree that, if at any time all or any part of any payment theretofore
applied by the Agent or the Banks to any of the Liabilities is or must be rescinded or returned by
the Agent or the Banks for any reason whatsoever (including, without limitation, the insolvency,
bankruptcy or reorganization of the Debtor), such Liabilities shall, for the purposes of this
guaranty, to the extent that such payment is or must be rescinded or returned, be deemed to have
continued in existence, notwithstanding such application by the Agent or the Banks, and this
guaranty shall continue to be effective or be reinstated, as the case may be, as to such
Liabilities, all as though such application by the Agent or the Banks had not been made.

     The Agent and the Banks may, from time to time, at their sole discretion and without notice to
any Guarantor, take any or all of the following actions: (a) be granted a security interest in any
property to secure any of the Liabilities or the Guaranty Obligations, (b) retain or obtain the
primary or secondary obligation of any obligor or obligors, in addition to the Guarantors, with
respect to any of the Liabilities, (c) extend or renew for one or more periods (whether or not
longer than the original period), alter or exchange any of the Liabilities, or release or
compromise any obligation of any nature of any other obligor with respect to any of the
Liabilities, (d) release its security interest in, or surrender, release or permit any substitution
or exchange for, all or any part of any property securing any of the Liabilities or any obligation
hereunder, or extend or renew for one or more periods (whether or not longer than the original
period) or release, compromise, alter or exchange any obligations of any nature of any obligor with
respect to any such property, and (e) resort to any Guarantor for payment of any of the
Liabilities, whether or not the Agent and the Banks (i) shall have resorted to any property
securing any of the Liabilities or (ii) shall have proceeded against any other obligor primarily or
secondarily obligated with respect to any of the Liabilities including without limitation any other
Guarantor (all of the actions referred to in preceding clauses (i) and (ii) being hereby expressly
waived by each Guarantor).

     Any amounts received by the Agent and the Banks from whatsoever source on account of the
Liabilities may be applied by it toward the payment of such of the Liabilities, and in such order
of application, as the Agent may from time to time elect.

     Until such time as this guaranty shall have been discontinued and the Agent and the Banks
shall have received payment of the full amount of all Liabilities and of all obligations of the
Guarantors hereunder, no payment made by or for the account of the Guarantors pursuant to this
guaranty shall entitle the Guarantors by subrogation or otherwise to any payment by the Debtor or
from or out of any property of the Debtor and the Guarantors shall not exercise any right or remedy
against the Debtor or any property of the Debtor by reason of any performance by the Guarantors of
this guaranty.

14

 

     The Guarantors hereby expressly waive: (a) notice of the acceptance by the Agent or the Banks
of this guaranty, (b) notice of the existence or creation or non-payment of all or any of the
Liabilities,
(c) presentment, demand, notice of dishonor, protest, and all other notices whatsoever, and (d) all
diligence in collection or protection of or realization upon the Liabilities or any part thereof,
any obligation hereunder, or any security for, or guaranty of, any of the foregoing.

     Each Bank may from time to time without notice to the Guarantors, assign or transfer its
Percentage (as defined in the Credit Agreement) or any or all of the Liabilities or any interest
therein; and, notwithstanding any such assignment or transfer or any subsequent assignment or
transfer thereof, such Liabilities shall be and remain Liabilities for the purposes of this
guaranty, and each and every immediate and successive assignee or transferee of any of the
Liabilities or of any interest therein shall, to the extent of the interest of such assignee or
transferee in the Liabilities, be entitled to the benefits of this guaranty to the same extent as
if such assignee or transferee were such Bank.

     Unless the Agent shall otherwise consent in writing, the Agent shall have the sole right to
enforce this Guaranty, as Agent as provided in the Credit Agreement, for the benefit of the Agent
and the Banks (including any transferee, as provided in the prior paragraph).

     Each Guarantor hereby warrants to the Agent and the Banks that such Guarantor now has, and
will continue to have independent means of obtaining information concerning the affairs, financial
condition and business of the Debtor. Neither the Agent nor the Bank shall have any duty or
responsibility to provide the Guarantors with any credit or other information concerning the
affairs, financial condition or business of the Debtor which may come into the Agent’s or the
Bank’s possession.

     No delay on the part of the Agent or any Bank in the exercise of any right or remedy shall
operate as a waiver thereof, and no single or partial exercise by the Agent or any Bank of any
right or remedy shall preclude other or further exercise thereof or the exercise of any other right
or remedy; nor shall any modification or waiver of any of the provisions of this guaranty be
binding upon the Agent or any Bank except as expressly set forth in a writing duly signed and
delivered on behalf of the Agent and the Required Banks (as defined in the Credit Agreement). No
action of the Agent or the Banks permitted hereunder shall in any way affect or impair the rights
of the Agent or the Banks and the obligations of the Guarantors under this guaranty. For the
purposes of this guaranty, Liabilities shall include all obligations of the Debtor to the Agent or
the Banks specified as Liabilities, notwithstanding any right or power of the Debtor or anyone else
to assert any claim or defense as to the invalidity or unenforceability of any such obligation, and
no such claim or defense shall affect or impair the obligations of the Guarantors hereunder, and
shall specifically include, without limitation, any and all interest, fees or commissions included
in the Liabilities and accruing or payable after the commencement of any bankruptcy or insolvency
proceedings, notwithstanding any provision or rule of law which might restrict the rights of the
Bank to collect such obligations from the Debtor. The obligations of the Guarantors under this
guaranty shall be absolute and unconditional irrespective of any circumstance whatsoever which
might constitute a legal or

15

 

equitable discharge or defense of any Guarantor. The Guarantors hereby
acknowledge that there are no conditions to the effectiveness of this guaranty.

     This guaranty shall be binding upon each Guarantor, and upon the successors and assigns of
each Guarantor.

     Wherever possible, each provision of this guaranty shall be interpreted in such a manner as to
be effective and valid under applicable law, but if any provision of this guaranty shall be
prohibited by or invalid under such law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision or the remaining
provisions of this guaranty.

     THE VALIDITY, CONSTRUCTION AND ENFORCEABILITY OF THIS GUARANTY SHALL BE GOVERNED BY THE
INTERNAL LAWS OF THE STATE OF MINNESOTA, WITHOUT GIVING EFFECT TO CONFLICT OF LAWS PRINCIPLES
THEREOF, BUT GIVING EFFECT TO FEDERAL LAWS OF THE UNITED STATES APPLICABLE TO NATIONAL BANKS.

     THE AGENT AND THE BANKS (BY ACCEPTING THIS GUARANTY) AND THE GUARANTORS HEREBY EXPRESSLY WAIVE
ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS
GUARANTY OR UNDER ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE
FUTURE BE DELIVERED IN CONNECTION HEREWITH AND AGREE THAT ANY SUCH ACTION OR PROCEEDING SHALL BE
TRIED BEFORE A COURT AND NOT BEFORE A JURY.

     AT THE OPTION OF THE AGENT, THIS GUARANTY MAY BE ENFORCED IN ANY FEDERAL COURT OR MINNESOTA
STATE COURT SITTING IN MINNEAPOLIS OR ST. PAUL, MINNESOTA; AND THE GUARANTORS CONSENT TO THE
JURISDICTION AND VENUE OF ANY SUCH COURT AND WAIVE ANY ARGUMENT THAT VENUE IN SUCH FORUMS IS NOT
CONVENIENT. IN THE EVENT ANY GUARANTOR COMMENCES ANY ACTION IN ANOTHER JURISDICTION OR VENUE UNDER
ANY TORT OR CONTRACT THEORY ARISING DIRECTLY OR INDIRECTLY FROM THE RELATIONSHIP CREATED BY THIS
GUARANTY, THE AGENT, AT ITS OPTION, SHALL BE ENTITLED TO HAVE THE CASE TRANSFERRED TO ONE OF THE
JURISDICTIONS AND VENUES ABOVE DESCRIBED, OR IF SUCH TRANSFER CANNOT BE ACCOMPLISHED UNDER
APPLICABLE LAW, TO HAVE SUCH CASE DISMISSED WITHOUT PREJUDICE.

Attention: Mr. Kevin G. Moug

Re: Pledge of Stock

Dear Mr. Moug:

     Reference is made to that certain Credit Agreement, dated as of October 2, 2007 (as thereafter
amended, the “Credit Agreement”) among Varistar Corporation (the “Borrower”), the Banks named
therein, and between U.S. Bank National Association, as agent for the Banks (the “Agent”).
Capitalized terms used in the Credit Agreement and not otherwise defined shall have the meanings
set forth therein.

     It is the understanding of the Agent and the Banks that Otter Tail Corporation (the “Company”)
owns all of the capital stock of the Borrower and that for this reason the Company gains benefit
from the extensions of credit by the Banks under the Credit Agreement. It is a term and condition
of the Credit Agreement that the Company enter into this letter agreement to induce the Banks and
the Agent to extend credit to the Borrower under the Credit Agreement.

     The Company has agreed with the Banks and the Agent that until such time as the Credit
Agreement and all Letters of Credit issued thereunder shall have terminated, and all obligations of
the Borrower under the Credit Agreement and each Loan Document shall have been paid and satisfied
in full, the Company will not grant, create, incur, assume or suffer to exist any Lien on the stock
of the Borrower.

     THIS AGREEMENT, dated as of October 2, 2007, is between OTTER TAIL CORPORATION, a Minnesota

Preliminary Statement

     The Subordinated Creditor has made loans, and may hereafter make loans, to Varistar
Corporation, a Minnesota corporation (together with its successors and assigns called the
“Borrower”). Pursuant to a Credit Agreement, dated as of October 2, 2007 (as hereafter amended,
modified, renewed or replaced from time to time, the “Credit Agreement”) among the Borrower, the
Banks (as defined therein) and the Agent, such loan shall be permitted under the covenants thereof
and this Agreement (as hereafter amended, modified, renewed or replaced from time to time) shall be

including each Note and each Letter of Credit Agreement, as defined therein; (b) each swap,
cap, collar and other interest rate agreement between the Borrower and the Agent or any
Bank, including any ISDA Master Agreement and confirmations thereunder; and (c) any
amendment, modification, extension, renewal or replacement of the foregoing, including
without limitation any document entered into by the Borrower and other lenders that would
provide for loans and extensions of credit to refinance, in full, the loans and extensions
of credit made by the Agent and the Banks under the Credit Agreement and documents described
in (b) above (called a “Refinancing Lender”) and upon entry into such documents with
the Refinancing Lender, upon written confirmation by the Agent to the Borrower, references
to the Agent and the Banks in this Agreement shall be deemed to refer to the Refinancing
Lender.

20

 

     “Senior Default” shall mean: (a) the occurrence of any “Event of Default” or
similar occurrence under any Senior Credit Document, including the occurrence of any Event
of Default as defined in the Credit Agreement; or (b) the failure of the Subordinated
Creditor to perform any agreement made by it hereunder and such failure shall continue
beyond any grace period expressly applicable thereto.

     “Senior Liabilities” shall mean all obligations of the Borrower under any
Senior Credit Document (including this Agreement) to the Agent, the Banks, their successors
and assigns or to a Refinancing Lender, howsoever created, arising or evidenced, whether
direct or indirect, absolute or contingent, or now or hereafter existing, or due or to
become due, including without limitation any such obligations that arise after the filing of
a petition by or against the Borrower under the Bankruptcy Code, even if the obligations do
not accrue because of the automatic stay under Bankruptcy Code Section 362 or otherwise.

     “Subordinated Liabilities” shall mean all obligations of the Borrower to the
Subordinated Creditor, howsoever created, arising or evidenced, whether direct or indirect,
absolute or contingent or now or hereafter existing, or due or to become due.

     2. The payment of all Subordinated Liabilities shall be postponed and subordinated to the
payment in full of all Senior Liabilities, and no payments or other distributions whatsoever in
respect of any Subordinated Liabilities shall be made, nor shall any property or assets of the
Borrower be applied to the purchase or other acquisition or retirement of any Subordinated
Liabilities; provided, however, that, until such time as a Senior Default shall have occurred and
be continuing, there are excepted from the terms of this Section payments to the Subordinated
Creditor by the Borrower that are listed as exceptions on Schedule A attached hereto.

     3. In the event of any dissolution, winding up, liquidation, readjustment, reorganization or
other similar proceedings relating to the Borrower or to its property (whether voluntary or
involuntary, partial or complete, and whether in bankruptcy, insolvency or receivership, or upon an
assignment for the benefit of creditors, or any other marshaling of the assets and liabilities of
the Borrower, or any sale of all or substantially all of the assets of the Borrower, or otherwise),
the Senior Liabilities shall first be paid in full before the Subordinated Creditor shall be
entitled to receive and to retain any payment or distribution in respect of the Subordinated
Liabilities, and, in order to implement the foregoing, (a) all payments and distributions of any
kind or character in respect of the Subordinated Liabilities to which the Subordinated Creditor
would otherwise be entitled shall be made directly to the Agent for application to the Senior
Liabilities, (b) the Subordinated Creditor shall promptly file a claim or claims, in the form
required in such proceedings, for the full outstanding amount of the Subordinated Liabilities, and
shall cause said claim or claims to be approved and all payments and other distributions in respect
thereof to be made directly to the Agent for application to the Senior Liabilities, and (c) the
Subordinated Creditor hereby irrevocably agrees that the Agent may, at its sole discretion, in the
name of the Subordinated Creditor or otherwise, demand, sue for, collect, receive and receipt for
any and all such payments or

21

 

distributions, and file, prove, and vote or consent in any such
proceedings with respect to, any and all claims of the Subordinated Creditor relating to the
Subordinated Liabilities.

     4. In the event that the Subordinated Creditor receives any payment or other distribution of
any kind or character from the Borrower or from any other source whatsoever in respect of any of
the Subordinated Liabilities, other than as expressly permitted by the terms of this Agreement,
such payment or other distribution shall be received in trust for the Agent and promptly turned
over by the Subordinated Creditor to the Agent. The Subordinated Creditor will mark its books and
records to clearly indicate that the Subordinated Liabilities are subordinated in accordance with
the terms of this Agreement, and will cause to be clearly inserted in any promissory note or other
instrument which at any time evidences any of the Subordinated Liabilities a statement to the
effect that the payment thereof is subordinated in accordance with the terms of this Agreement.

     5. All payments and distributions received by the Agent in respect of the Subordinated
Liabilities, to the extent received in or converted into cash, may be applied by the Agent first to
the payment of any and all expenses (including attorneys, fees and legal expenses) paid or incurred
by the Agent in enforcing this Agreement or in endeavoring to collect or realize upon any of the
Subordinated Liabilities or any security therefor, and any balance thereof shall, solely as between
the Subordinated Creditor and the Agent, be applied by the Agent, in such order of application as
the Agent may from time to time elect, toward the payment of the Senior Liabilities remaining
unpaid; but, as between the Borrower and its creditors, no such payments or distributions of any
kind or character shall be deemed to be payments or distributions in respect of the Senior
Liabilities; and, notwithstanding any such payments or distributions received by the Agent in
respect of the Subordinated Liabilities and so applied by the Agent toward the payment of the
Senior Liabilities, the Subordinated Creditor shall not be subrogated to the then existing rights
of the Agent, if any, in respect of the Senior Liabilities until such time as the Agent shall have
indefeasably received payment of the full amount of the Senior Liabilities.

     6. The Subordinated Creditor will not without the prior written consent of the Agent: (a)
enforce or attempt to enforce any rights to collection of the Subordinated Liabilities or exercise
any rights against assets of the Borrower in connection with the Subordinated Liabilities, (b)
transfer, assign, or subordinate to any liabilities other than the Senior Liabilities, the
Subordinated Liabilities or any rights in respect thereof, provided, that the Subordinated
Liabilities may be transferred to a Subsidiary (as defined in the Credit Agreement) of the
Subordinated Creditor, subject to receipt by the Agent of an acknowledgement by such Subsidiary of
this Agreement in form and substance reasonably acceptable to the Agent; (c) take any collateral
security for the Subordinated Liabilities; (c) convert the Subordinated Liabilities into any other
form of debt of the Borrower, whether or not the Subordinated Creditor shall have the right to do
so under the documents governing the Subordinated Liabilities, (d) amend any provisions of the
documents governing the Subordinated Liabilities, or (e) commence, or join with any other creditor
in commencing, any bankruptcy, reorganization or insolvency proceedings with respect to the
Borrower.

22

 

     7. The Subordinated Creditor hereby waives: (a) notice of acceptance by the Agent or the Banks
of this Agreement; (b) notice of the existence or creation or non-payment of all or any of the
Senior Liabilities; and (c) all diligence in collection or protection of or realization upon the
Senior Liabilities or any thereof or any security therefor.

     8. This Agreement shall in all respects be a continuing agreement and shall remain in full
force and effect (notwithstanding, without limitation, the death, incompetence or dissolution of
the Subordinated Creditor or that at any time or from time to time all Senior Liabilities may have
been paid in full).

     9. The Agent and the Banks have taken no action to induce the Subordinated Creditor to accept
the Subordinated Liabilities, or extend credit constituting the Subordinated Liabilities, and the
Subordinated Creditor has not relied, in any way, on the Agent or the Banks in its extension of the
Subordinated Liabilities. The Subordinated Creditor has independent means of obtaining information
concerning the affairs, financial condition and business of the Borrower and the Agent and the
Banks shall have no duty or responsibility to provide the Subordinated Creditor with any credit or
other information concerning the Borrower.

     10. The Agent and the Banks may, from time to time, at its sole discretion and without notice
to the Subordinated Creditor, take any or all of the following actions: (a) retain or obtain a
security interest in any property of the Borrower, or any other party granting such security
interest to the Agent, to secure any of the Senior Liabilities, (b) retain or obtain the primary or
secondary obligation of any other obligor or obligors with respect to any of the Senior
Liabilities, (c) extend or renew for one or more periods (whether or not longer than the original
period), alter or exchange any of the Senior Liabilities, increase the amount of the Senior
Liabilities, amend or modify in any regard the Senior Credit Documents, or release or compromise
any obligation of any nature of any obligor with respect to any of the Senior Liabilities, and (d)
release any security interest in, or surrender, release or permit any substitution or exchange for,
all or any part of any property securing any of the Senior Liabilities or release, compromise,
alter or exchange any obligations of any nature of any obligor with respect to any such property.

     11. The Agent and the Banks may, from time to time, without notice to the Subordinated
Creditor, assign or transfer any or all of the Senior Liabilities or any interest therein; and,
notwithstanding any such assignment or transfer or any subsequent assignment or transfer thereof,
such Senior Liabilities shall be and remain Senior Liabilities for the purposes of this Agreement,
and every immediate and successive assignee or transferee of any of the Senior Liabilities or of
any interest therein shall, to the extent of the interest of such assignee or transferee in the
Senior Liabilities, be entitled to the benefits of this Agreement to the same extent as if such
assignee or transferee were the Agent or a Bank.

     12. The Agent and the Banks shall not be prejudiced in their rights under this Agreement by
any act or failure to act of the Borrower or the Subordinated Creditor, or any noncompliance of the
Borrower or the Subordinated Creditor with any agreement or obligation, regardless of any knowledge
thereof which the Agent or any Bank may have or with which the Agent or any Bank may be charged;
and no action of the

23

 

Agent or any Bank permitted hereunder shall in any way affect or impair the
rights of the Agent and the Banks and the obligations of the Subordinated Creditor under this
Agreement.

     13. No delay on the part of the Agent or the Banks in the exercise of any right or remedy
shall operate as a waiver thereof, and no single or partial exercise by the Agent or the Banks of
any right or remedy shall preclude other or further exercise thereof or the exercise of any other
right or remedy; nor shall any modification or waiver of any of the provisions of this Agreement be
binding upon the Bank except as expressly set forth in a writing duly signed and delivered on
behalf of the Agent. For the purposes of this Agreement, Senior Liabilities shall include all
obligations of the Borrower to the Agent and the Banks specified in the definition thereof,
notwithstanding any right or power of the Borrower or anyone else to assert any claim or defense as
to the invalidity or unenforceability of any such obligation, and no such claim or defense shall
affect or impair the agreements and obligations of the Subordinated Creditor hereunder.

     14. This Agreement shall be binding upon the Subordinated Creditor and upon the heirs, legal
representatives, successors and assigns of the Subordinated Creditor; and, to the extent that the
Borrower or the Subordinated Creditor is either a partnership or a corporation, all references
herein to the Borrower and to the Subordinated Creditor, respectively, shall be deemed to include
any successor or successors, whether immediate or remote, to such partnership or corporation. If
more than one party shall execute this Agreement, the term “Subordinated Creditor” as used herein
shall mean all parties executing this Agreement and each of them, and all such parties shall be
jointly and severally obligated hereunder.

     15. This Agreement shall be construed in accordance with and governed by the laws of the State
of Minnesota. Wherever possible each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision of this Agreement
shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Agreement.

     16. THE SUBORDINATED CREDITOR AND THE AGENT EACH HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN
ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT OR UNDER ANY
AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN
CONNECTION HEREWITH, AND AGREE THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND
NOT BEFORE A JURY.

     17. AT THE OPTION OF THE AGENT, THIS AGREEMENT MAY BE ENFORCED IN ANY FEDERAL COURT OR
MINNESOTA STATE COURT SITTING IN MINNEAPOLIS OR ST. PAUL, MINNESOTA; AND THE SUBORDINATED CREDITOR
CONSENTS TO THE JURISDICTION AND VENUE OF ANY SUCH COURT AND WAIVES ANY ARGUMENT THAT VENUE IN SUCH
FORUMS IS NOT CONVENIENT. IN THE

24

 

EVENT THE SUBORDINATED CREDITOR COMMENCES ANY ACTION IN ANOTHER
JURISDICTION OR VENUE UNDER ANY TORT OR CONTRACT THEORY ARISING DIRECTLY OR INDIRECTLY FROM THE
RELATIONSHIP CREATED BY THIS NOTE THE AGENT, AT ITS OPTION, SHALL BE ENTITLED TO HAVE THE CASE
TRANSFERRED TO ONE OF THE JURISDICTIONS AND VENUES ABOVE DESCRIBED, OR IF SUCH TRANSFER CANNOT
BE ACCOMPLISHED UNDER APPLICABLE LAW, TO HAVE SUCH CASE DISMISSED WITHOUT PREJUDICE.

	 	Reply to Fargo office
	 
	 	Direct: 701-451-3567

To: The Banks party to the

Credit Agreement described herein

Bank of America, N.A.

Keybank National Association

Wells Fargo Bank, National Association

U.S. Bank, National Association

Ladies and Gentlemen:

     I have acted as counsel to Varistar Corporation, a Minnesota corporation (the “Company”), in
connection with the transactions contemplated by that certain Credit Agreement, dated as of
October 2, 2007, entered into among the Company, the Banks, as defined therein, and U.S.
Bank National Association, as Agent (the “Credit Agreement”), and to the Material Subsidiaries as
defined in the Credit Agreement (the “Material Subsidiaries”) in connection with that certain
Guaranty dated as of October 2, 2007, entered into by each Material Subsidiary (the
“Guaranty”). This opinion is being delivered to you pursuant to Section 6.1(e) of the Credit
Agreement. Capitalized terms used herein, except as otherwise specifically defined herein, are
used with the same meaning as defined in the Credit Agreement.

     In connection with this opinion, I have examined the following documents:

     (a) The Articles or Certificate of Incorporation of the Company and each Material
Subsidiary;

     (b) The Bylaws of the Company and each Material Subsidiary;

     (c) Resolutions of the Board of Directors of each Material Subsidiary;

     (d) An executed copy of the Credit Agreement and the Guaranty; and

     (e) An executed copy of the Notes.

 

 

     I also have examined such other documents and reviewed such questions of law as I have
considered necessary and appropriate for the purposes of this opinion.

     In rendering my opinions set forth below, I have assumed the authenticity of all documents
submitted to me as originals, the genuineness of all signatures (other than the signatures of
officers of the Company and each Material Subsidiary) and the conformity to authentic originals of
all documents submitted to me as copies. I also have assumed the legal capacity for all purposes
relevant hereto of all natural persons (other than officers of the Company and each Material
Subsidiary) and, with respect to all parties to agreements or instruments relevant hereto other
than the Company and each Material Subsidiary, that such parties had the requisite power and
authority (corporate or otherwise) to execute, deliver and perform such agreements or instruments,
that such agreements or instruments have been duly authorized by all requisite action (corporate or
otherwise), executed and delivered by such parties and that such agreements or instruments are the
valid, binding and enforceable obligations of such parties. As to questions of fact material to my
opinion, I have relied upon representations and certificates of officers and other employees of the
Company and each Material Subsidiary (known by me to have authority to make such representations
and certifications on behalf of the Company and each Material Subsidiary) and certificates of
public officials.

     Based on the foregoing, I am of the opinion that:

     (i) The Company and each Material Subsidiary are each a corporation duly organized, validly
existing and in good standing under the laws of the state of its incorporation, and each is duly
qualified and in good standing as a foreign corporation in all other jurisdictions in which its
respective present operations or properties require such qualification, except where failure so to
qualify or to be in good standing would not constitute an Adverse Event.

     (ii) The Company and each Material Subsidiary each has full corporate power and authority to
(a) own and operate its properties and assets and carry on its business as presently conducted, as
described in the Company’s Annual Report or Form 10-K for the year ended December 31, 2006, and (b)
enter into and perform its obligations under the Loan Documents to which it is a party.

     (iii) The execution and delivery of the Loan Documents, the borrowing by the Company under the
Credit Agreement and the performance by the Company and Guarantor of their respective obligations
under the Loan Documents to which it is a party have been duly authorized by all necessary
corporate action, and the Loan Documents have been duly executed and delivered on behalf of the
Company and each Material Subsidiary and the Loan Documents have been duly executed and delivered
on behalf of the Company and each Material Subsidiary, as applicable and constitute valid and
binding obligations of the Company and each Material Subsidiary, enforceable in accordance with
their respective terms.

     (iv) There is no provision in (a) the Company’s or any Material Subsidiary’s Articles or
Certificate of Incorporation or Bylaws, (b) any indenture, mortgage, contract or agreement to

 

 

which the Company or any Material Subsidiary is a party or by which the Company or any Material
Subsidiary or its respective properties are bound, (c) any law, statute, rule or regulation or (d)
any writ, order or decision of any court or governmental instrumentality binding on the Company or
any Material Subsidiary which would be contravened by the execution, delivery or performance by the
Company or any Material Subsidiary of the Loan Documents to which it is a party, except in the
case of clauses (b) and (d) for any such contravention which would not constitute an Adverse Event.

     (v) There are no actions, suits or proceedings pending or, to the best of my knowledge,
threatened against the Company or any Material Subsidiary before any court or arbitrator or by or
before any administrative agency or government authority, which, if adversely determined, could
reasonably be expected to constitute an Adverse Event.

     The opinions expressed above are limited to the laws of the States of Minnesota and the
federal laws of the United States and I express no opinion as to the laws of any other
jurisdiction.

     The foregoing opinions are being furnished to you solely for your benefit and may not be
relied upon by, nor may copies be delivered to, any other person without my prior written consent.

Very truly yours,

George A. Koeck

General Counsel and Corporate Secretary

Agent, under which the Assignor has agreed to make Revolving Loans and Term Loans, and to issue or
participate in the risk of issuance of Letters of Credit, in each instance in amounts of up to
those set forth in Item IV (such amount equals the original commitment of the Assignor and
may have been, or may be, reduced or increased by other assignments by, or to, the Assignor, and
will be reduced by the assignment under this Agreement) and the Bank Group has agreed to make
Revolving Loans and Term Loans, and to issue or participate in the risk of issuance of Letters of
Credit, in each instance in amounts of up to those set forth in Item V. Such Revolving

Letters of Credit, and the Bank’s participation in any unreimbursed drawing under any Letter of
Credit or any advance or loans made in connection with drawings under any Letter of Credit are
sometimes called the “Advances” or each “Advance,, hereinafter. Unless the context clearly
indicates otherwise, all other terms used in this Agreement shall have the meanings given them by,

recourse and without representation or warranty (except as expressly provided in this

with the Credit Agreement and all of the Advances, including without limitation the right to
receive payment of principal, and interest on such percentage of the Assignor’s Advances, and the

assignment, and to indemnify the Agent or any other party under the Credit Agreement and to pay all
other amounts payable by a Bank (in such percentage of the aggregate obligations of the Bank Group)
under or in connection with the Credit Agreement.

     The interest of the Assignor under the Credit Agreement (including the portion of the
Assignor’s Advances and all such commitments, loans, participations, rights, benefits, obligations,
liabilities and indemnities) which the Assignee purchases and assumes hereunder is hereinafter
referred to as its “Assigned Share”. The day upon which the Assignee shall make the payment

Participations in, or may have assigned or may hereafter assign, portions of its interest in the
