The Applicable Commitment Fee Rate and Applicable Margin shall be adjusted ten (10) Business Days

(b) Upon request by the Borrower, the Swing Line Bank may, at its sole discretion, make
loans (each a “Swing Line Loan” and, collectively, the “Swing Line Loans”)
to the

14

 

Borrower from time to time from the date hereof until the Termination Date, provided, that the aggregate unpaid principal amount of the Swing Line Loans at any one time
outstanding shall not exceed the Swing Line Guideline.

     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

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, on 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.

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 requests for 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 3:00 p.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, provided that the
Agent shall not be required to make any amount of the requested Revolving Loans available to
the Borrower unless the Agent shall have received such amount from the Banks, and
provided, further, that unless the Agent shall have been notified in writing
by a Bank prior to the time requested Revolving Loans shall be made hereunder that such

15

 

Bank does not intend to make its Percentage share of the requested Revolving Loans
available to the Agent, the Agent may assume that such Bank has made such Percentage share
available to the Agent and the Agent may in reliance on such assumption make Revolving Loans
available to the Borrower a corresponding amount. In any case that 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. 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.

     Section 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:

(a) 1:00 p.m., Minneapolis time, on 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 (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

16

 

if a Default or Event of Default shall
exist and the Agent has given notice to the Borrower that no such continuations or conversions may
be made.

     Section 2.5 Evidence of Indebtedness.

(a) Each Bank and the Swing Line Bank shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of the Borrower to such Bank resulting
from each Loan made by such Bank or Swing Line Bank, including the amounts of principal and
interest payable and paid to such Bank or Swing Lien Bank from time to time hereunder.

(b) The Agent, acting for this purpose as an agent of the Borrower, shall maintain accounts
in which it shall record (i) the amount of each Loan made hereunder, the type thereof and
the Interest Period applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Bank and the Swing Line Bank
hereunder and (iii) the amount of any sum received by the Agent hereunder for the account of
the Banks and the Swing Line Bank and each Bank’s and Swing Line Bank’s share thereof (the
“Register”).

(c) The entries made in the accounts maintained pursuant to paragraph (a) or (b) of this
Section 2.5 shall be prima facie evidence of the existence and amounts of the
obligations recorded therein; provided that the failure of any Bank, the Swing Line Bank or
the Agent to maintain such accounts or any error therein shall not in any manner affect the
obligation of the Borrower to repay the Loans in accordance with the terms of this
Agreement. The Borrower, the Agent and the Banks may treat each person whose name is
recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes
of this Agreement, notwithstanding notice to the contrary. The Register shall be available
for inspection by the Borrower or any Bank, at any reasonable time and from time to time
upon reasonable prior notice.

(d) Any Bank or the Swing Line Bank may request that Loans made by it be evidenced by a
promissory note. In such event, the Borrower shall prepare, execute and deliver to such
Bank or Swing Line Bank a Revolving Note payable to such Bank and its registered assigns or
a Swing Line Note payable to the Swing Line Bank and its registered assigns.

     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” 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

17

 

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 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.

18

 

(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 and 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) $50,000,000 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 Agent agrees to
issue letters of credit for the account of the Borrower or any Subsidiary, as provided in
Section 2.8(f), upon request by the Borrower to the Agent (such letters of credit as
any of them may be amended, supplemented, extended or confirmed from time to time, along
with letters of credit issued under the Existing Credit Agreement, being herein collectively
called the “Letters of Credit”). No Letter of Credit shall expire later than the
earlier to occur of (x) the fifth Business Day prior to the Termination Date and (y) one
year after its issuance, provided that, that Letters of Credit may automatically
extend absent notice of termination by the Agent; provided, further, that the expiry date of
a Letter of Credit may be later than the fifth Business Day prior to the Termination Date if
the Borrower has, on or before the fifth Business Day prior to the Termination Date, (i)
posted cash collateral to the Agent on terms satisfactory to the Agent in an amount equal to
105% of the Letter of Credit Obligations with respect to such Letter of Credit to be held
and applied in accordance with the terms of Section 10.3, (ii) delivered to the
Agent a backstop letter of credit issued by a financial institution reasonably satisfactory
to the Agent, or (iii) otherwise entered into an alternative arrangement reasonably
satisfactory to the Agent with respect to such Letter of Credit. 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 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

19

 

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 $50,000,000 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; provided that this paragraph shall not relieve
the Agent or any Bank of any liability resulting from the gross negligence, bad
faith or willful misconduct of the Agent or such Bank, or otherwise affect any
defense or other right that the Borrower may have as a result of such gross
negligence, bad faith or willful misconduct. Such reimbursement may, subject to
satisfaction of the conditions in Article VI 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. 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

20

 

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, bad faith 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 Agent 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.

(vi) The Borrower will pay to Agent for the account of each Bank (subject to
Section 2.11 with respect to any Defaulting Bank) in accordance with its
Percentage a letter of credit fee with respect to each Letter of Credit equal to an
amount, calculated on the basis of daily amount available to be drawn on each Letter
of Credit from time to time, in each case for the period from and including

21

 

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 (subject to Section 2.11
with respect to any Defaulting Bank), promptly after
receiving any payment in respect of letter of credit fee referred to in this
clause (vi), 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 0.25% 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 be subject to the
conditions precedent that the Borrower shall have executed and delivered such
applications and other customary 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, or a backstop letter of credit issued by a financial institution
reasonably satisfactory to the Agent, or otherwise entered into an alternative
arrangement reasonably satisfactory to the Agent with respect to any outstanding
Letters of Credit.

(d) Indemnification; Release. The 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
gross negligence, bad faith or willful misconduct 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.

22

 

(e) Existing Letters of Credit. Letters of Credit previously issued by the Agent
under the Existing Credit Agreement 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 Increase to Commitments. The Borrower may, on up to two occasions,
increase the Commitments hereunder, by giving notice to the Agent, specifying the dollar amount of
the increase (which shall be in a minimum amount of $10,000,000 plus integral multiples of
$5,000,000, and which shall not result in total aggregate Commitments hereunder in excess of
$250,000,000); provided, however, that an increase in the Commitments hereunder may only be made at
a time when no Default or Event of Default shall have occurred and be continuing. The Borrower may
increase the Commitments by either increasing a Commitment with an existing Bank or obtaining a
Commitment from a new financial institution, the selection of which shall require the consent of
the Agent, not to be unreasonably withheld or delayed. The Borrower, the Agent and each Bank or
other financial institution that is increasing its Commitment or extending a new Commitment shall
enter into an amendment to this Agreement setting forth the amounts of the Commitments, as so
increased, providing that any new financial institution extending a new Commitment shall be a Bank
for all purposes under this Agreement and effecting such other changes as the Borrower and the
Agent shall deem necessary or advisable in connection with such increase of the Commitments
hereunder. No such amendment shall require the approval or consent of any Bank whose Commitment is
not being increased and no Bank shall be required to increase its Commitment unless it shall so
agree in writing. Upon the execution and delivery of such amendment as provided above, this
Agreement shall be deemed to be amended accordingly and the Agent shall adjust the funded amount of
the Advances of the Banks so that each Bank (including the Banks with new or increased Commitments)
shall hold their respective Percentages (as amended by such amendment) of the Advances outstanding
and the unfunded Commitments (and each Bank shall so fund any increased amount of Advances).

     Section 2.10 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.

     Section 2.11 Defaulting Banks. Notwithstanding any provision of this Agreement to the
contrary, if any Bank becomes a Defaulting Bank, then the following provisions shall apply for so
long as such Bank is a Defaulting Bank (the “Default Period”):

(a) Commitment Fees. Such Defaulting Bank’s Commitment, outstanding Loans and
Participation Interests shall be excluded for purposes of calculating the Commitment Fees

23

 

and Letter of Credit commissions payable to Banks, and such Defaulting Bank shall not be
entitled to receive any Commitment Fee or Letter of Credit commission pursuant to
Section 3.2 and Section 2.8(c)(vi), respectively, with respect to such
Defaulting Bank’s Commitment and such fees with respect to such Defaulting Bank shall cease
to accrue.

(b) Voting. Such Defaulting Bank shall be deemed not to be a “Bank” for purposes of
voting on any matters and the Commitment, outstanding Loans and Participation Interests
of such Defaulting Bank shall not be included in determining whether all Banks or the
Required Banks have taken or may take any action hereunder (including any consent to any
amendment or waiver pursuant to Section 12.2).

(c) Prepayments. To the extent permitted by applicable law, until the end of the
Default Period, any voluntary prepayment of the Loans shall, if Borrower so directs at the
time of making such voluntary prepayment, be applied to the Loans of other Banks as if such
Defaulting Bank had no Loans outstanding.

(d) Reallocation of Swing Line Loans and Letters of Credit. If any Swing Line Loans
or Letters of Credit are outstanding at the time a Bank becomes a Defaulting Bank then:

(i) all or any part of such Defaulting Bank’s Participation Interests in such Swing
Line Loans or Letters of Credit shall be reallocated among the non-Defaulting Banks
in accordance with their respective Percentages but only to the extent (x) the sum
of all non-Defaulting Banks’ Loans and Participation Interests plus such Defaulting
Bank’s Loans and Participation Interests does not exceed the total of all
non-Defaulting Banks’ Commitments and (y) the conditions set forth in Article
VI are satisfied at such time; and

(ii) if the reallocation described in clause (i) above cannot, or can only
partially, be effected, the Borrower shall within three (3) Business Days following
notice by the Agent prepay such Defaulting Bank’s portion of the Swing Line Loans,
or deliver collateral for such Defaulting Bank’s portion of drawings under Letters
of Credit to be held as provided in Section 10.3 (to the extent not fully
reallocated as provided in clause (i) above after giving effect to any
partial reallocation thereunder), or enter into an alternative arrangement
satisfactory to the Agent with respect to such Defaulting Bank’s portion of the
Swing Line Loans or Letters of Credit.

(e) Application of Payments. Subject to application of voluntary prepayments as
described in Section 2.11(c), any amount otherwise payable to a Defaulting Bank
hereunder (whether on account of principal, interest, fees or otherwise and including any
amount that would otherwise be payable to such Defaulting Bank pursuant to Sections
2.7(c), 2.8(c)(iv), 4.1, 4.2, 4.3, 4.4,
4.5 or 10.4) shall, in lieu of being distributed to such Defaulting Bank, be
applied by the Agent (i) first, to the payment of any amounts owing by such
Defaulting Bank to the Agent hereunder, (ii) second, pro rata, to the payment of any
amounts owing by such Defaulting Bank to the Swing Line Bank hereunder, (iii) third,
to the funding of any Loan or the funding of any Participation Interest in respect of which
such Defaulting Bank has failed to fund its Percentage thereof

24

 

as required by this
Agreement, as determined by the Agent, (iv) fourth, at the election of the Agent and
the Borrower, either to (x) repay Borrower Obligations to the non-Defaulting Banks, in such
order of application as the Agent shall designate, or (y) be held on account with the Agent
as cash collateral for future funding obligations of the Defaulting Bank under this
Agreement, (v) fifth, pro rata, to the payment of any amounts owing to the Borrower
or the non-Defaulting Banks as a result of any judgment of a court of competent jurisdiction
obtained by the Borrower or any Bank against such Defaulting Bank as a result of such
Defaulting Bank’s breach of its obligations under this Agreement and (vi) sixth, to
such Defaulting Bank or as otherwise directed by a court of competent jurisdiction.

(f) Remedy by Defaulting Bank. In the event that the Agent, the Borrower and the
Swing Line Bank each agrees that a Defaulting Bank has adequately remedied all matters that
caused such Bank to be a Defaulting Bank, then the Participation Interests of the Banks
shall be readjusted to reflect the inclusion of such Bank’s Commitment and on such date such
Bank shall purchase at par such of the Loans of the other Banks (other than Swing Line
Loans) as the Agent shall determine may be necessary in order for such Bank to hold such
Loans in accordance with its Percentage. In addition, at such time as a Defaulting Bank
ceases to be a Defaulting Bank, the Agent shall cause any and all collateral delivered by
the Borrower pursuant to Section 2.11(d)(ii) to be promptly released and returned to
the Borrower, and there shall be no retroactive adjustment to or accrual of any Commitment
Fees or Letter of Credit commissions that would otherwise have been payable to such
Defaulting Bank during the Default Period if such Defaulting Bank had not been a Defaulting
Bank.

(g) Non-exclusive Remedies. The rights and remedies against a Defaulting Bank under
this Section 2.11 are in addition to other rights and remedies which Borrower may
have against such Defaulting Bank with respect to any Funding Default and which the Agent or
any Bank may have against such Defaulting Bank with respect to any Funding Default.

     Section 2.12 Replacement of Banks. If the Agent or a Bank provides the Borrower with
a notice pursuant to Section 5.1, 5.2 or 5.3 or if any Bank becomes a
Defaulting Bank, then the Borrower may, at its sole expense and effort, upon notice to such
Defaulting Bank and the Agent, require such Bank or Defaulting Bank to assign and delegate, without
recourse, all of its interests, rights and obligations under this Agreement and the related Loan
Documents to an assignee that shall assume such obligations (which assignee may be another Bank, if
a Bank accepts such assignment), provided that:

(a) The Borrower shall have paid to the Agent the assignment fee specified in Section
12.3(b)(ii);

(b) Such Defaulting Bank shall have received payment of an amount equal to the outstanding
principal of its Loans and its portion of the Swing Line Participation Amount, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder and under the
other Loan Documents from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrower (in the case of all other amounts); and

25

 

(c) Such assignment does not conflict with applicable law.

     Section 2.13 Authorized Representatives. The Borrower shall act hereunder through the
Authorized Representatives designated from time to time and all notices and requests to be given
and received by the Borrower, including requests for Loans and designation of amounts of Advances
and Interest Periods, shall be given by and directed to such Authorized Representatives.

     Section 2.14 Extensions of Commitments.

(a) The Borrower may from time to time, pursuant to the provisions of this Section
2.14, agree with one or more Banks holding Commitments to extend the termination date,
and otherwise modify the terms of such Commitments or any portion thereof (including,
without limitation, by increasing the interest rate or fees payable in respect of such
Commitments or any portion thereof (each, such modification an “Extension”) pursuant to one
or more written offers (each, an “Extension Offer”) made from time to time by the Borrower
to all Banks, in each case on a pro rata basis (based on their respective Percentages) and
on the same terms to each such Bank. In connection with each Extension, the Borrower will
provide notification to the Agent (for distribution to the Banks), no later than 60 days
prior to the Termination Date of the requested new termination date for the extended
Commitments (each an “Extended Termination Date”) and the due date for Bank responses. In
connection with any Extension, each Bank wishing to participate in such Extension shall,
prior to such due date, provide the Agent with a written notice thereof in a form reasonably
satisfactory to the Agent. Any Bank that does not respond to an Extension Offer by the
applicable due date shall be deemed to have rejected such Extension.

(b) Each Extension shall be subject to the following:

(i) no Default or Event of Default shall have occurred and be continuing at the time
any Extension Offer is delivered to the Banks or at the time of such Extension;

(ii) except as to interest rates, fees, termination date and increase to Commitments
under Section 2.9 (which shall, subject to immediately clause (iii) below,
be determined by the Borrower and set forth in the relevant Extension Offer), the
Commitment of any Bank extended pursuant to any Extension shall have the same terms
as the Commitments of the Banks that did not agree to the Extension Offer;

(iii) the final termination date of the Commitments to be extended pursuant to an
Extension shall be later than the final termination date of the Commitments of the
Banks that did not agree to the Extension Offer;

(iv) if the aggregate amount of Commitments in respect of which Banks shall have
accepted an Extension Offer exceeds the maximum aggregate amount of Commitments
offered to be extended by the Borrower pursuant to the relevant Extension Offer,
then such Commitments shall be extended ratably up to such

26

 

maximum amount based on
the relative Commitments of the Banks that accepted such Extension Offer;

(v) all documentation in respect of such Extension shall be consistent with the
foregoing, and all written communications by the Borrower generally directed to the
applicable Banks in connection therewith shall be in form and substance consistent
with the foregoing and otherwise reasonably satisfactory to the Agent;

(vi) any applicable Minimum Extension Condition shall be satisfied; and

(vii) no Extension shall become effective unless, on the proposed effective date of
such Extension, the conditions set forth in Section 6.2 shall be satisfied
(with all references in such Section to a request for a Loan being deemed to be
references to the Extension on the applicable date of such Extension), and the Agent
shall have received a certificate to that effect dated the applicable date of such
Extension and executed by an Authorized Representative of the Borrower.

(c) If at the time any Extension of Commitments (as so extended, “Current Extension
Commitments”) becomes effective, there will be Commitments or Revolving Loans attributable
to a prior Extension that will remain outstanding (collectively, the “Prior Extension
Commitments”), then, if the interest rate spread applicable to any such Current Extension
Commitments exceeds the interest rate spread applicable to such Prior Extension Commitments
by more than 0.25%, then the interest rate spread applicable to such Prior Extension
Commitments shall be increased so that it equals the interest rate spread applicable to the
Current Extension Commitments (calculated as provided above).

(d) The consummation and effectiveness of any Extension will be subject to a condition set
forth in the relevant Extension Offer (a “Minimum Extension Condition”) that a minimum
amount be agreed to by the Banks subject to such Extension (to be determined in the
Borrower’s discretion and specified in the relevant Extension Offer, but in no event less
than $25,000,000, unless another amount is agreed to by the Agent). For the avoidance of
doubt, it is understood and agreed that the provisions of Section 4.5 will not apply
to Extensions of Commitments pursuant to Extension Offers made pursuant to and in accordance
with the provisions of this Section 2.14, including to any payment of interest or
fees in respect of any Commitments or Revolving Loans that have been made extended or made
pursuant to an Extension at a rate or rates different from those paid or payable in respect
of Commitments or Revolving Loans of Banks that did not extend their Commitments, in each
case as is set forth in the relevant Extension Offer.

(e) The Banks hereby irrevocably authorize the Agent to enter into amendments
(collectively, “Extension Amendments”) to this Agreement and the other Loan Documents as may
be necessary in order establish new classes of Commitments and Revolving Loans created
pursuant to an Extension, in each case on terms consistent with this Section 2.14.
Notwithstanding the foregoing, the Agent shall have the right (but not the obligation) to
seek the advice or concurrence of the Required Banks with respect to any matter contemplated
by this Section 2.14 and, if the Agent seeks such advice or concurrence, the Agent
shall be permitted to enter into such amendments with the

27

 

Borrower in accordance with any instructions received from such Required Banks and
shall also be entitled to refrain from entering into such amendments with the Borrower
unless and until it shall have received such advice or concurrence; provided,
however, that whether or not there has been a request by the Agent for any such advice or
concurrence, all such Extension Amendments entered into with the Borrower by the Agent
hereunder shall be binding on the Banks. Without limiting the foregoing, in connection with
any Extension, the Borrower and any Material Subsidiary shall execute such agreements,
confirmations or other documentation as the Agent shall reasonably request to accomplish the
purposes of this Section 2.14.

(f) In connection with any Extension, the Borrower shall provide the Agent at least 60
days’ (or such shorter period as may be agreed by the Administrative Agent) prior written
notice thereof, and shall agree to such procedures, if any, as may be reasonably established
by, or acceptable to, the Agent to accomplish the purposes of this Section 2.14.

     Section 2.15 Tax Matters. No Person can become a Bank unless it is either a United States Person
or an “exempt recipient” within the meaning of Treasury Regulations Section 1.6049-4(c) based on
the indicators set forth therein, unless such Person represents and warrants to the Agent and the
Borrower that it is entitled to receive interest payments without withholding or deduction of any
taxes and executes and delivers to the Agent and the Borrower a United States Internal Revenue
Service Form W8BEN, W8ECI, W-8 IMY and/or W-9 or any successor to either of such forms, as
appropriate, properly completed a claiming complete exemption from withholding and deduction of all
Federal Income Taxes. A “United States Person” means any citizen, national or resident of the
United States, any corporation or other entity created or organized in or under the laws of the
United States or any political subdivision hereof or any estate or trust, in each case that is not
subject to withholding of United States Federal income taxes or other taxes on payment of interest,
principal of fees hereunder.

ARTICLE III INTEREST AND FEES

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

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 (subject to Section 2.11 with respect to
any Defaulting Bank) pay fees (the “Commitment Fees”) to the Agent for the account of the
Banks (in according with their respective Percentages) in an amount determined by applying the
Applicable Commitment Fee Rate per annum to the average daily unused amount of the Commitments
(with the face amount of all Letters of Credit deemed usage for such purpose, but Swing Line Loans
not deemed usage) of the Banks for the period from the date hereof to the Termination Date.

     Section 3.3 Computation. Interest and Commitment Fees shall be computed on the basis of actual
days elapsed and a year of 360 days, provided, that any interest or fee calculated with reference

ARTICLE IV PAYMENTS, PREPAYMENTS, REDUCTION OR TERMINATION

OF THE CREDIT AND SETOFF

     Section 4.1 Repayment. Principal of the Loans, together with all accrued and unpaid interest
thereon, shall be due and payable on the Termination Date.

     Section 4.2 Optional Prepayments. The Borrower may, upon at least one (1) Business Day’s (in the
case of Base Rate Advances, or three (3) Business Days’ in the case of LIBOR Advances) 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. In
the event that the Loans are being refinanced, any such notice may be made contingent upon the
closing of such refinancing. Any such prepayment must be accompanied by accrued and unpaid
interest on the amount prepaid. Each partial prepayment shall be in an amount of $50,000 or an
integral multiple thereof. Any prepayment of a LIBOR Advance shall be in an amount equal to the
remaining entire principal balance of such Advance. In the event that the Loans are being
refinanced, any such notice may be made contingent upon the closing of such refinancing.

     Section 4.3 Optional Reduction or Termination of Commitment. The Borrower may, at any time, upon
no less than one (1) Business Day 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. In the event that the Loans are being refinanced, any such notice may be made contingent
upon the closing of such refinancing. Upon any reduction in the Commitment pursuant to this
Section, the Borrower shall pay to the Agent for the account of the

29

 

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 one (1) Business Day 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 Loans, all accrued and unpaid interest thereon, all unpaid
Commitment Fees accrued to the date of such termination and all other unpaid obligations of the
Borrower to the Banks hereunder. All payment described in this Section is subject to the
provisions of Section 2.6. 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 (unless the Borrower has provided cash collateral or a backstop letter of
credit issued by a financial institution reasonably satisfactory to the Agent, or otherwise entered
into an alternative arrangement reasonably satisfactory to the Agent with respect to any
outstanding Letters of Credit).

     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 (subject only to
required withholding by the Borrower in the case of non-compliance by a Bank with the requirements
of Section 12.3(e)) 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
Material Subsidiary Guaranties 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 change after the date hereof of any law,
rule, regulation, treaty or directive 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;

(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 (excluding any
reserve or other requirement reflected in the calculation of LIBOR Rate (Reserve Adjusted))
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 as a
consequence of this Agreement or the Loans made by such Bank; or

(d) any other condition (other than any condition relating to taxes, duties, or other
charges as set forth in clause (a) above) 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 to a level below which such Bank could have achieved but for such change
(taking into consideration such Bank’s policies with respect to capital adequacy);

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: (i) which
additional amounts 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

31

 

reductions; or (ii) unless such Bank is generally requiring payment under comparable provisions of
its agreements with similarly situated borrowers.

     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), or in the case of Section 5.2(b), the Agent or the Required Banks determine, 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; or

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

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 or convert any such LIBOR Advance to a Base
Rate Advance, without premium or penalty on the last day of the current Interest Period with
respect thereto.

     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 subsection (a) or (c) would
reasonably 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
would constitute an Adverse Event. No Default or Event of Default has occurred and is continuing.

34

 

     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, except for such orders, consents, approvals, licenses,
authorizations, validations, filings, recordings, registrations or exemptions as have been made or
obtained and are in full force and effect.

     Section 7.5 Financial Statements and Condition. The Borrower’s audited consolidated financial
statements as of December 31, 2009, and the Borrower’s unaudited quarterly financial statements as
at March 31, 2010, as heretofore furnished to the Banks, have been prepared in accordance with GAAP
on a consistent basis (except, in the case of the unaudited quarterly financial statements, for the
absence of footnotes and for year-end audit adjustments) and fairly present in all material
respects the financial condition of the Borrower and the Subsidiaries, taken as a consolidated
enterprise, 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, 2009, 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, would 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, except where
noncompliance thereof would not constitute an Adverse Event.

     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 would constitute an Adverse Event. 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 would 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

35

 

provisions of ERISA and the Code setting forth those requirements, except where noncompliance
would not constitute an Adverse Event. No Reportable Event which would be an Adverse Event, has
occurred and is continuing with respect to any Plan. As of each January 1, all of the minimum
funding standards applicable to such Plans have been satisfied, except where nonsatisfaction would
not constitute an Adverse Event, and there exists no event or condition which would permit the
institution of proceedings to terminate any Plan under Section 4042 of ERISA, except for any event
or condition which would not constitute an Adverse Event.

     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, or valid leasehold interests in or easements or other limited
property interests in, its real properties necessary in the ordinary course of its business and
good and sufficient title to its other material properties, except for minor defects in title that
do not materially interfere with its ability to conduct its business and to utilize such assets for
their intended purposes and except where the failure to have such title or other property interests
described above would not constitute an Adverse Event. None of the properties, revenues or assets
of the Borrower or any of the Material Subsidiaries is subject to a Lien, except for Liens
disclosed in the consolidated financial statements referred to in Section 7.5 or permitted
under Section 9.8.

     Section 7.12 Taxes. Each of the Borrower and the Material Subsidiaries has filed all federal and
material 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 of
which it has received notice 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, charges or assessments 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, and other than taxes, fees, charges or assessments with
respect to which the failure to pay would not constitute an Adverse Event). No tax Liens have been
filed and no material claims are being asserted with respect to any such taxes, fees or charges,
except for Liens or claims which would not constitute an Adverse Event.

     Section 7.13 Trademarks, Patents. Each of the Borrower and the Material Subsidiaries possesses or
has the right, by way of ownership, license or otherwise, 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, except where the lack of such possession or right or where the
existence of such conflict would not constitute an Adverse Event.

36

 

     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.

     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.

ARTICLE VIII AFFIRMATIVE COVENANTS

and cash flow for the Borrower and its Subsidiaries for such quarter and for the period from

(g) Promptly upon becoming aware of the occurrence thereof, notice of the institution of any
litigation, arbitration or governmental proceeding, or the rendering of a judgment or
decision in such litigation or proceeding, which, in each case if adversely determined,
would constitute an Adverse Event.

38

 

(h) Promptly upon becoming aware of the occurrence thereof, notice of any violation as to
any environmental matter by the Borrower or any Material Subsidiary and of the commencement
of any judicial or administrative proceeding relating to health, safety or environmental

its jurisdiction of incorporation and its qualification to transact business in each jurisdiction

     Section 8.5 Inspection. Permit representatives of the Agent to visit and inspect any
of its properties, corporate books and financial records, to examine and to make copies of its
books of accounts and other financial records, and to discuss the affairs, finances and accounts of
the Borrower and the Subsidiaries with, and to be advised as to the same by, its officers at such
reasonable times during normal business hours of the Borrower and the Subsidiaries, upon reasonable
advance notice to the Borrower and the Subsidiaries; provided that, so long as no Event of Default
has occurred and is continuing, the expenses of the Agent and its representatives for such visits,
inspections and examinations shall be at the expense of the Agent, but any such visits,
inspections, and examinations made while any Event of Default is continuing shall be at the expense
of the Borrower.

     Section 8.6 Maintenance of Properties. Maintain its properties used or useful in the
conduct of its business in good condition, repair and working order, and supplied with all
necessary equipment, and make all necessary repairs, renewals, replacements, betterments and
improvements thereto, all as may be necessary so that the business carried on in connection

39

 

therewith may be properly and advantageously conducted at all times, except where the failure to do
so would not constitute an Adverse Event.

that permits the preparation of financial statements in accordance with GAAP.

requirements of ERISA and of the Code and with all material applicable rulings and regulations
issued under the provisions of ERISA and of the Code, including without limitation minimum funding
standards, except where the failure so to comply would not constitute an Adverse Event.

     Section 8.10 Environmental Matters. Observe and comply with all laws, rules,
regulations and orders of any government or government agency relating to health, safety,
pollution, hazardous materials or other environmental matters to the extent non compliance would
constitute an Adverse Event.

senior unsecured Indebtedness of the Borrower, and are and remain pari passu and of equal rank and
seniority with all senior unsecured Indebtedness of the Borrower (without limiting the obligation

acquiesced in by the Borrower, any Material Subsidiary or Otter Tail Power Company or shall
remain for 30 days undismissed, undischarged, unstayed or unbonded, or the Borrower, any
Material Subsidiary or Otter Tail Power Company shall consent to or acquiescence in such a
proceeding; provided that any dissolution or proceeding not prohibited by Section
9.1 or Section 9.2 shall not constitute an Event of Default;

(h) A final judgment or judgments for the payment of money in excess of the sum of
$10,000,000 in the aggregate (to the extent not covered by third-party insurance as to which
the insurer has not denied coverage in respect thereof) shall be rendered against the
Borrower or a Material Subsidiary, and there is a period of 30 consecutive days during which
(i) the Borrower or such Material Subsidiary has not discharged the same or provided for its
discharge in accordance with its terms, or (ii) the Borrower or such Material Subsidiary has
not procured a stay of execution, prior to any execution on such judgment or (iii) such

(i) The termination of any Plan by the Borrower or any ERISA Affiliate if in order to
effectuate such termination, the Borrower or any ERISA Affiliate would be required to make a
contribution to such Plan, or would incur a liability or obligation to such Plan, and the
requirement to make such contribution or the incurrence of such liability or obligations
shall constitute an Adverse Event, or the termination of any such Plan by the PBGC if in
order to effectuate such termination, the Borrower or any ERISA Affiliate would be required
to make a contribution to such Plan, or would incur a liability or
obligation to such Plan, and the requirement to make such contribution or the incurrence of
such liability or obligations shall constitute an Adverse Event;

(j) The maturity of any Indebtedness of the Borrower (other than Indebtedness under this
Agreement) or a Material Subsidiary in the aggregate in excess of $10,000,000 shall be
accelerated, or the Borrower or a Material Subsidiary shall fail to pay any such
Indebtedness (in excess of such amount) when due (beyond the applicable grace period with
respect thereto) or, in the case of such Indebtedness payable on demand, when demanded
(beyond the applicable grace period with respect thereto), or any other event shall occur or
condition shall exist and shall continue for more than the period of grace, if any,
applicable thereto and, in each case, such nonpayment or other event shall have the effect
of causing, or permitting (any required notice having been given and grace period having
expired) the holder of any such Indebtedness (in excess of such amount) or any trustee or
other Person acting on behalf of such holder to cause, such Indebtedness to become due prior
to its stated maturity; provided that this clause (j) shall not apply to secured
Indebtedness that becomes due as a result of the voluntary sale or transfer of the property
or assets securing such Indebtedness if such sale or transfer is permitted hereunder and
under the documents providing for such Indebtedness, and provided further, that an Event of
Default under this clause (j) caused by the occurrence of a breach or default with respect
to Indebtedness in the aggregate in excess of $10,000,000 shall be cured for purposes of
this Agreement upon the Person asserting such breach or default waiving such breach or
default or upon the Borrower or a Material Subsidiary curing such breach or default if, at
the time of such waiver or such cure the Agent has not exercised any rights or remedies with
respect to an Event of Default under this clause (j);

(k) Any material provision of any Loan Document shall not be, or shall cease to be,
enforceable and binding in accordance with its terms (other than as permitted hereunder or
thereunder), or the Borrower or any Material Subsidiary shall disavow or contest in writing
its obligations under such Loan Document (other than as permitted hereunder or thereunder;
or

(l) Either (i) the Borrower shall cease to own, directly or indirectly, all of the voting
stock of Varistar Corporation, or (ii) any person or group (as such terms are used in
Sections 13(d) and 14(d) of the Securities Exchange Act of 1934), that owned less than 5% of
the shares of any voting class stock of the Borrower shall have acquired more than 25% of
the shares of such voting stock.

     Section 10.2 Remedies. If (a) any Event of Default described in Sections
10.1(e), (f) or (g) shall occur and be continuing with respect to the Borrower,
the Commitments shall automatically terminate and the outstanding unpaid principal balance of the
Notes, the accrued

52

 

interest thereon and all other obligations of the Borrower to the Banks and the
Agent under the Loan Documents shall automatically become immediately due and payable; or (b) any
other Event of Default shall occur and be continuing, then the Agent may (with the consent of the
Required Banks) take any or all of the following actions (and shall take any or all of the
following actions on direction of the Required Banks): (i) declare the Commitments terminated,
whereupon the Commitments shall terminate, (ii) declare that the outstanding unpaid principal
balance of the Notes, the accrued and unpaid interest thereon and all other obligations of the
Borrower to the Banks and the Agent under the Loan Documents to be forthwith due and payable,
whereupon the Notes, all accrued and unpaid interest thereon and all such obligations shall
immediately become due and payable, in each case without demand or notice of any kind, all of which
are hereby expressly waived, anything in this Agreement or in the Notes to the contrary
notwithstanding, (iii) exercise all rights and remedies under any other Loan Document, and (iv)
enforce all rights and remedies under any applicable law.

     Section 10.3 Letters of Credit. In addition to the foregoing remedies, if any Event
of Default described in Section 10.1(e), (f) or (g) shall have occurred and
be continuing, or if any other Event of Default shall have occurred and be continuing and the Agent
shall have declared that the principal balance of the Notes is due and payable, the Agent may, with
the consent of the Required Banks, and shall on direction of the Required Banks, require the
Borrower to pay to the Agent an amount equal to all Letter of Credit Obligations. Such payment
shall be in immediately available funds or in similar cash collateral reasonably acceptable to the
Agent and shall be pledged to the Agent for the ratable benefit of the Banks. Such amount shall be
held by the Agent in a cash collateral account until the outstanding Letters of Credit are
terminated without payment or are paid and Letter of Credit Obligations with respect thereto are
payable. In the event the Borrower defaults in the payment of any Letter of Credit Obligations,
the proceeds of the cash collateral account shall be applied to the payment thereof. The Borrower
acknowledges and agrees that the Banks would not have an adequate remedy at law for failure by the
Borrower to pay immediately to the Agent the amount provided under this Section, and that the Agent
shall, on behalf of the Banks, have the right to require the Borrower to perform specifically such
undertaking whether or not any of the Letter of Credit Obligations are due and payable. Upon the
failure of the Borrower to make any payment required under this Section, the Agent, on behalf of
the Banks, may proceed to use all remedies available at law or equity to enforce the obligation of
the Borrower to pay or reimburse the Agent. The balance of any payment due under this Section
shall bear interest payable on demand until paid in full at a per annum rate equal to the Base Rate
plus 2.00%.

     Section 10.4 Setoff. In addition to, and without limitation of, any rights of the
Banks under applicable law, if any Event of Default occurs and is continuing, upon written
direction by the Agent to such effect any and all deposits (including all account balances, whether
provisional or final and whether or not collected or available) and any other Indebtedness at any
time held or owing by any Bank to or for the credit or account of the Borrower may be offset and
applied toward the payment of the Borrower Obligations then due and payable owing to such Bank.
Each Bank agrees to promptly notify the Borrower and the Agent after any such setoff and
application made by such Bank; provided that the failure to give such notice shall not affect the
validity of such setoff and application.

lawful agent of such Bank to the extent set forth herein and under the other Loan Documents.

     Section 11.2 Non-Reliance on Agent. Each Bank agrees that it has, independently and
without reliance on the Agent or any other Bank, and based on such documents and information as it
has deemed appropriate, made its own credit analysis of the Borrower and decision to enter into
this Agreement and that it will, independently and without reliance upon the Agent, and based on
such documents and information as it shall deem appropriate at the time, continue to make its own

required to keep informed as to the performance or observance by the Borrower of this Agreement and
the Loan Documents or to inspect the properties or books of the Borrower. Except for notices,
reports and other documents and information expressly required to be furnished to the Banks by the
Agent hereunder, the Agent shall not have any duty or responsibility to provide any Bank with any

(or any of its related companies) which may come into the Agent’s possession.

     Section 11.3 Responsibility of the Agent and Other Matters.

(a) The Agent shall have no duties or responsibilities except those expressly set forth in
this Agreement and those duties and liabilities shall be subject to the limitations and
qualifications set forth in this Section. The duties of the Agent shall be mechanical and
administrative in nature.

(b) Neither the Agent nor any of its directors, officers or employees shall be liable for
any action taken or omitted (whether or not such action taken or omitted is within or
without the Agent’s responsibilities and duties expressly set forth in this Agreement) under
or in connection with this Agreement, or any other instrument or document in connection
herewith, except for gross negligence, bad faith or willful misconduct. Without limiting
the foregoing, neither the Agent nor any of its directors, officers or employees shall be
responsible for, or have any duty to examine: (i) the genuineness, execution, validity,
effectiveness, enforceability, value or sufficiency of the Loan Agreements; (ii) the
collectability of any amounts owed by the Borrower; (iii) any recitals or statements or

54

 

correct and to have been signed or sent or made by a proper person or persons or entity. The Agent
may consult counsel and shall be entitled to act, and shall be fully protected in-any
action taken in good faith, in accordance with advice given by counsel. The Agent may
employ agents and attorneys-in-fact and shall not be liable for the default or misconduct of
any such agents or attorneys-in-fact selected by the Agent with reasonable care. The Agent
shall not be bound to ascertain or inquire as to the performance or
observance of any of the terms, provisions or conditions of this Agreement or the Notes on
the Borrower’s part.

     Section 11.4 Action on Instructions. The Agent shall be entitled to act or refrain
from acting, and in all cases shall be fully protected in acting or refraining from acting under
this Agreement or the Notes or any other instrument or document in connection herewith or therewith
in accordance with instructions in writing from (i) the Required Banks except for instructions
which under the express provisions hereof must be received by the Agent from all the Banks, and
(ii) in the case of such instructions, from all the Banks.

     Section 11.5 Indemnification. To the extent the Borrower does not reimburse and save
the Agent harmless according to the terms hereof for and from all costs, expenses and disbursements
in connection herewith or with the other Loan Documents, such costs, expenses and disbursements to
the extent reasonable shall be borne by the Banks ratably in accordance with their Percentages and
the Banks hereby agree on such basis (a) to reimburse the Agent for all such reasonable costs,
expenses and disbursements on request and (b) to indemnify and save harmless the Agent against and
from any and all losses, obligations, penalties, actions, judgments and suits and other reasonable
costs, expenses and disbursements of any kind or nature whatsoever which may be imposed on,
incurred by or asserted against the Agent, other than as a consequence of actual gross negligence,
bad faith or willful misconduct on the part of the Agent, arising out of or in connection with this
Agreement or the Notes or any instrument or document in connection herewith or therewith, or any
request of the Banks, including without limitation the reasonable and documented costs, expenses
and disbursements in connection with defending itself against any claim or liability, or answering
any subpoena, related to the exercise or performance of any of its powers or duties under this
Agreement or the other Loan Documents or the taking of any action under or in connection with this
Agreement or the Notes.

     Section 11.6 U.S. Bank National Association and Affiliates. With respect to U.S. Bank
National Association’s Commitment and any Loans by U.S. Bank National Association under this
Agreement and any Note and any interest of U.S. Bank National Association in any Note, U.S. Bank
National Association shall have the same rights, powers and duties under this Agreement and such
Note as any other Bank and may exercise the same as though it were not the Agent. U.S. Bank
National Association and its affiliates may accept deposits from, lend money to, and generally
engage, and continue to engage, in any kind of business with the Borrower as if U.S. Bank National
Association were not the Agent.

     Section 11.7 Notice to Holder of Notes. The Agent may deem and treat the payees of
the Notes as the owners thereof for all purposes unless a written notice of assignment, negotiation
or transfer thereof has been filed with the Agent. Any request, authority or consent of any holder
of any Note shall be conclusive and binding on any subsequent holder, transferee or assignee of
such Note.

55

 

     Section 11.8 Successor Agent. The Agent may resign at any time by giving at least 30
days written notice thereof to the Banks and the Borrower, with the effectiveness of such
resignation subject to the appointment and acceptance of a successor Agent. Upon any such
resignation, the Required Banks shall have the right to appoint a successor Agent (subject to the
Borrower’s approval, such approval not to be unreasonably withheld or delayed). If no successor
Agent shall have been appointed by the Required Banks and shall have accepted such appointment
within 30 days after the retiring Agent’s giving notice of resignation, then the retiring Agent
may, but shall not be required to, on behalf of the Banks, appoint a successor Agent with a
combined capital and surplus of at least $500,000,000 (or an affiliate of any such bank)..

     Section 11.9 Co-Documentation Agents and Lead Arranger. None of the Co-Documentation
Agents or Lead Arranger shall have any duties, responsibilities or liabilities in such capacities.

ARTICLE XII MISCELLANEOUS

     Section 12.1 No Waiver and Amendment. No failure on the part of the Banks or the
holder of the Notes to exercise and no delay in exercising any power or right hereunder or under
any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise
of any power or right preclude any other or further exercise thereof or the exercise of any other
power or right. The remedies herein and in any other instrument, document or agreement delivered
or to be delivered to the Banks hereunder or in connection herewith are cumulative and not
exclusive of any remedies provided by law. No notice to or demand on the Borrower not required
hereunder or under the Notes shall in any event entitle the Borrower to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the right of the Banks or the
holder of the Notes to any other or further action in any circumstances without notice or demand.

     Section 12.2 Amendments, Etc. No amendment or waiver of any provision of this
Agreement, nor consent to any departure by the Borrower therefrom, shall in any event be effective
unless the same shall be in writing and signed by the Borrower and the Agent upon direction of the
Required Banks (subject to Section 2.11 with respect to any Defaulting Bank) and then such waiver
or consent shall be effective only in the specific instance and for the specific purpose for which
given; provided that Agent may, with the consent of Borrower only, amend, modify or
supplement this Agreement to cure any ambiguity, omission, defect or inconsistency, so long as such
amendment, modification or supplement does not materially and adversely affect the rights of any
Bank; provided further, however, that no amendment, waiver or consent
shall, unless agreed to by the Agent and each of the Banks directly affected thereby (subject to
Section 2.11 with respect to any Defaulting Bank):

(a) increase the amounts of or extend the terms of the Commitments of such Bank (it being
understood that a waiver or modification of any condition precedent, covenant, Default,
Event of Default, mandatory prepayment or mandatory reduction of the Commitments shall not
constitute an extension or increase of any Commitment of any Bank);

56

 

(b) decrease or forgive the principal of, or decrease the rate of interest on, the Notes of
such Bank, or decrease any fees or other amounts payable hereunder to such Bank;

(c) postpone any date fixed for any payment of principal of, or interest on, the Notes of
such Bank, or any fees or other amounts payable hereunder to such Bank;

(d) release all or substantially all of the Material Subsidiaries from the Material
Subsidiary Guaranty (except pursuant to a transaction or series of transactions permitted by
Section 8.12, 9.1 or 9.2) or release all or substantially all of the
collateral held subject to Section 10.3, except as contemplated by such Section; or

(e) reduce the percentage in the definition of Required Banks or amend this
Section 12.2.

provided, further that amendments, waivers or consents adversely affecting the
rights of the Agent shall also require the consent of the Agent. Notwithstanding the foregoing
provisions of this Section 12.2, with the agreement and consents of the Persons referred to
therein, and without the necessity of obtaining the approval of any other Banks hereunder, (i)
amendments may be entered into as provided in Section 2.9 and (ii) Extension Amendments may
be entered into pursuant to Section 2.14.

     Section 12.3 Assignments and Participations.

(a) Assignments. Each Bank shall have the right, subject to the further provisions
of this Sections 12.3, to sell or assign all or any part of its Commitments, Loans,
Notes, and other rights and obligations under this Agreement and related documents (such
transfer, an “Assignment”) to any commercial lender, other financial institution or
other entity other than the Borrower or one of its Subsidiaries or affiliates (an
“Assignee”). Upon such Assignment becoming effective as provided in
Section 12.3(b), the assigning Bank shall be relieved from the portion of its
Commitment, obligations to indemnify the Agent and other obligations hereunder to the extent
assumed and undertaken by the Assignee, and to such extent the Assignee shall have the
rights and obligations of a “Bank” hereunder. Notwithstanding the foregoing, unless
otherwise consented to by the Borrower and the Agent, each Assignment shall be in the
initial principal amount of not less than $10,000,000 in the aggregate for all Loans and
Commitments assigned, or an integral multiple of $1,000,000 if above such amount. Each
Assignment shall be documented by an agreement between the assigning Bank and the Assignee
(an “Assignment and Assumption Agreement”) substantially in the form of
Exhibit E attached hereto.

(b) Effectiveness of Assignments. An Assignment shall become effective hereunder
when all of the following shall have occurred: (i) the Agent and the Borrower (or, following
occurrence and during continuance of an Event of Default, the Agent only and not the
Borrower) shall consent to such Assignment (which consent shall not be unreasonably
withheld), by either written notice of such consent or by executing and delivering such
Assignments, provided that no such consents shall be required for an assignment to one of
the Banks or an affiliate of a Bank or an Approved Fund, (ii) either the assigning Bank or
the Assignee shall have paid a processing fee of $3,500 to the

57

 

Agent for its own account (unless waived by the Agent), (iii) the Assignee shall have
submitted the Assignment and Assumption Agreement to the Agent with a copy for the Borrower,
and shall have provided to the Agent information the Agent shall have reasonably requested
to make payments to the Assignee, (iv) the assigning Bank and the Agent shall have agreed
upon a date upon which the Assignment shall become effective, and (v) the Agent shall have
recorded such Assignment in the Register; provided that assignments pursuant to Section
2.12 shall not require the signature or agreement of the assigning Bank to become
effective, and any processing fee in connection with such assignments may be paid by the
Borrower. Upon the Assignment becoming effective, (x) if requested by the assigning Bank,
the Agent and the Borrower shall make appropriate arrangements so that new Notes are issued
to the assigning Bank and the Assignee; and (y) the Agent shall forward all payments of
interest, principal, fees and other amounts that would have been made to the assigning Bank,
in proportion to the percentage of the assigning Bank’s rights transferred, to the Assignee.
Any assignment or transfer by a Bank of rights or obligations under this Agreement that
does not comply with clauses 12.3(a) and (b) shall be treated for purposes of this Agreement
as a sale by such Bank of a participation in such rights and obligations in accordance with
Section 12.3(c).

(c) Participations. Each Bank shall have the right, subject to the further
provisions of this Section 12.3, to grant or sell a participation in all or any part
of its Loans, Notes and Commitments (a “Participation”) to any commercial lender,
other financial institution or other entity (a “Participant”) without the consent of
the Borrower, the Agent of any other party hereto. The Borrower agrees that if amounts
outstanding under this agreement and the Notes are due and unpaid, or shall have been
declared or shall have become due and payable upon the occurrence and during the continuance
of an Event of Default, each Participant shall be deemed to have the right of setoff in
respect of its Participation in amounts owing under this Agreement and any Note to the same
extent as if the amount of its Participation were owing directly to it as a Bank under this
agreement or any note; provided, that such right of setoff shall be subject to the
obligation of such Participant to share with the Banks, and the Banks agree to share with
such Participant, as provided in Section 4.5. The Borrower also agrees that each
Participant shall be entitled to the benefits of Article V with respect to its
Participation, provided, that no Participant shall be entitled to receive any greater amount
pursuant to such Sections than the transferor Bank would have been entitled to receive in
respect of the amount of the Participation transferred by such transferor Bank to such
Participant had no such transfer occurred.

(d) Limitation of Rights of any Assignee or Participant. Notwithstanding anything
in the foregoing to the contrary, except in the instance of an Assignment that has become
effective as provided in Section 12.3(b), (i) no Assignee or Participant shall have
any direct rights hereunder, (ii) the Borrower, the Agent and the Banks other than the
assigning or selling Bank shall deal solely with the assigning or selling Bank and shall not
be obligated to extend any rights or make any payment to, or seek any consent of, the
Assignee or Participant, (iii) no Assignment or Participation shall relieve the assigning or
selling Bank from its Commitment to make Loans hereunder or any of its other obligations
hereunder and such Bank shall remain solely responsible for the performance hereof, the
(iv) no Assignee or Participant, other than an affiliate of the assigning or

58

 

selling Bank, shall be entitled to require such Bank to take or omit to take any action
hereunder, except that such Bank may agree with such Assignee or Participant that such Bank
will not, without such Assignee’s or Participant’s consent, take any action which would, in
the case of any principal, interest or fee in which the Assignee or Participant has an
ownership or beneficial interest: (x) extend the final maturity of any Loans or extend the
Termination Date, (y) reduce the interest rate on the Loans or the rate of the Commitment
Fees, or (z) forgive any principal of, or interest on, the Loans or any fees.

(e) Tax Matters. No Bank shall be permitted to enter into any Assignment or
Participation with any Assignee or Participant who (i) is not a United States Person or
(ii) is a United States Person that the Borrower may not treat as an “exempt recipient”
within the meaning of Treasury Regulations Section 1.6049-4(c) based on the indicators set
forth therein, unless such Assignee or Participant represents and warrants to such Bank, the
Agent and the Borrower that, as at the date of such Assignment or Participation, it is
entitled to receive interest payments without withholding or deduction of any taxes and such
Assignee or Participant executes and delivers to such Bank on or before the date of
execution and delivery of documentation of such Participation or Assignment, a United States
Internal Revenue Service Form W8BEN, W8ECI, W-8 IMY and/or W-9 or any successor to either of
such forms, as appropriate, properly completed an claiming complete exemption from
withholding and deduction of all Federal Income Taxes. A “United States Person” means any
citizen, national or resident of the United States, any corporation or other entity created
or organized in or under the laws of the United States or any political subdivision hereof
or any estate or trust, in each case that is not subject to withholding of United States
Federal income taxes or other taxes on payment of interest, principal of fees hereunder.

(f) Information. Each Bank may furnish any information concerning the Borrower in
the possession of such Bank from time to time to Assignees and Participants and potential
Assignees and Participants, so long as such entities agree in writing to keep such
information confidential in accordance with Section 12.17.

(g) Federal Reserve Bank. Nothing herein stated shall limit the right of any Bank
to assign a security interest in all or any portion of its rights herein and in any Note to
a Federal Reserve Bank; provided that no such assignment of a security interest shall
release a Bank from any of its obligations hereunder or substitute any such assignee for
such Bank as a party hereto.

     Section 12.4 Costs, Expenses and Taxes; Indemnification.

(a) The Borrower agrees, whether or not any Advance is made hereunder, to pay promptly on
written demand: (i) all reasonable and documented out-of-pocket costs and expenses of the
Agent (including the reasonable fees and expenses of one counsel to the Agent and Banks
taken as a whole) incurred in connection with the preparation, execution and delivery of the
Loan Documents and the preparation, negotiation and execution of any and all amendments to
each thereof, and (ii) all reasonable and documented out-of-pocket costs and expenses of the
Agent and each of the Banks incurred after the occurrence and during the continuance of an
Event of Default in

59

 

connection with the enforcement of the Loan Documents. The Borrower agrees to pay, and save
the Banks harmless from all liability for, any stamp or other taxes which may be payable
with respect to the execution or delivery of the Loan Documents. The Borrower agrees to
indemnify and hold the Banks harmless from any loss or expense which may arise or be created
by the acceptance in good faith by the Agent of telephonic or other instructions for making
Advances or disbursing the proceeds thereof, except to the extent resulting from the gross
negligence or willful misconduct.

(b) The Borrower agrees to defend, protect, indemnify, and hold harmless the Agent and each
and all of the Banks, each of their respective affiliates and each of the respective
officers, directors, employees and agents of each of the foregoing (each an “Indemnified
Person” and, collectively, the “Indemnified Persons”) from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims,
costs, expenses and disbursements of any kind or nature whatsoever (including, without
limitation, the reasonable fees and disbursements of counsel to such Indemnified Persons in
connection with any investigative, administrative or judicial proceeding, whether direct,
indirect or consequential and whether based on any federal or state laws or other statutory
regulations, including, without limitation, securities and commercial laws and regulations,
under common law or at equitable cause, or on contract or otherwise, arising out of or in
connection with the Commitments, the making of, management of and participation in the
Advances or the use or intended use of the proceeds of the Advances, provided that the
Borrower shall have no obligation under this Section 13.4(b) to an Indemnified
Person with respect to any of the foregoing to the extent resulting from the gross
negligence, bad faith or willful misconduct of such Indemnified Person or arising solely
from claims between one such Indemnified Person and another such Indemnified Person. The
indemnity set forth herein shall be in addition to any other obligations or liabilities of
the Borrower to each Indemnified Person under the Loan Documents or at common law or
otherwise. To the extent permitted by applicable law, any Person seeking to be indemnified
under this Section 12.4(b) shall, upon obtaining knowledge thereof, use commercially
reasonable efforts to give prompt written notice to the Borrower of the commencement of any
action or proceeding giving rise to such indemnification claim, provided that the failure to
give such notice shall not relieve the Borrower of any indemnification obligations
hereunder.

(c) The obligations of the Borrower under this Section 12.4 shall survive any
termination of this Agreement.

     Section 12.5 Notices.

(a) Except when telephonic or electronic notice is expressly authorized by this Agreement,
any notice or other communication to any party in connection with this Agreement shall be in
writing and shall be sent by manual delivery, facsimile transmission, overnight courier or
United States mail (postage prepaid) addressed to such party at the address specified on the
signature page hereof, or at such other address as such party shall have specified to the
other party hereto in writing. All periods of notice shall be measured from the date of
delivery thereof if manually delivered, from the date of sending thereof if sent by
facsimile transmission, from the first Business Day after the

60

 

date of sending if sent by overnight courier, or from four days after the date of mailing if
mailed; provided, however, that any notice to the Agent under
Article II shall be deemed to have been given only when received by the Agent.

(b) Financial statements, reports and letters under Section 8.1(a), (b), (c), (f), (g) and
(h) other ordinary course requests or communications by the Borrower to the Agent may be
sent by the Borrower to the Agent by e-mail, and may be distributed by the Agent to the Bank
by similar means or by posting to DebtX, or other coded commercial service selected for such
purpose by the Agent.

     Section 12.6 Successors. This Agreement shall be binding upon the Borrower, the Banks
and the Agent and their respective successors and permitted assigns, and shall inure to the benefit
of the Borrower, the Banks and the Agent and their respective successors and permitted assigns.
The Borrower shall not assign its rights or duties hereunder without the written consent of the
Banks.

     Section 12.7 Severability. Any provision of the Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other jurisdiction.

     Section 12.8 Subsidiary References. The provisions of this Agreement relating to
Subsidiaries shall apply only during such times as the Borrower has one or more Subsidiaries.

     Section 12.9 Captions. The captions or headings herein and any table of contents
hereto are for convenience only and in no way define, limit or describe the scope or intent of any
provision of this Agreement.

     Section 12.10 Entire Agreement. The Loan Documents embody the entire agreement and
understanding between the Borrower, the Banks and the Agent with respect to the subject matter
hereof and thereof. This Agreement supersedes all prior agreements and understandings relating to
the subject matter hereof.

GUARANTY

(Joint and Several)

     FOR VALUE RECEIVED and in consideration of entry by the Banks (as defined in the Second
Amended and Restated 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
Second Amended and Restated Credit Agreement, dated as of May 4, 2010 (as thereafter amended,
modified, extended, renewed, restated or replaced from time to time called the “Second Amended and
Restated Credit Agreement”) among the Banks, the Agent and OTTER TAIL CORPORATION, a Minnesota
corporation (hereinafter called the “Debtor”), the undersigned corporations (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 Second Amended and Restated 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.

     In addition to, and without limitation of, any rights of the Agent and the Banks under
applicable law, if any Event of Default occurs and is continuing under the Second Amended and
Restated Credit Agreement, upon written direction by the Agent to such effect any and all deposits
(including all account balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness (as defined in the Second Amended and Restated Credit
Agreement) at any time held or owing by the Agent or any Bank to or for the credit or account of
any Guarantor may be offset and applied toward the payment of the Liabilities and all obligations
of the Guarantors hereunder, whether or not the Liabilities and all obligations of the Guarantors
hereunder, or any part thereof, shall then be due.

     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). This guaranty is a guaranty of payment and performance and not merely a guaranty of
collection.

     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.

     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 Second Amended and Restated 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 Second Amended and Restated 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 Second Amended and
Restated 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

any Guarantor. The Guarantors hereby acknowledge that there are no conditions to the effectiveness

each Guarantor.

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.

Opinion of Counsel

May 4, 2010

To: The Banks party to the Second

Amended and Restated Credit

Agreement described herein

U.S. Bank National Association

Bank of America, N.A.

JPMorgan Chase Bank, N.A.

KeyBank National Association

Wells Fargo Bank, National Association

Bank of the West

Union Bank of California, N.A.

Ladies and Gentlemen:

     I have acted as counsel to Otter Tail Corporation, a Minnesota corporation (the “Company”), in
connection with entry by the Company into that certain Second Amended and Restated Credit
Agreement, dated as of May 4, 2010, among the Company, the Banks, as defined therein, and U.S. Bank
National Association, as Agent (the “Second Amended and Restated Credit Agreement”), and to the
Material Subsidiaries, as defined in the Second Amended and Restated Credit Agreement (the
“Material Subsidiaries”), in connection with entry by the Material Subsidiaries into that certain
Material Subsidiary Guaranty, dated as of May 4, 2010 (the “Material Subsidiary Guaranty”). This
opinion is being delivered to you pursuant to Section 6.1 of the Second Amended and Restated Credit
Agreement. Capitalized terms used herein, except as otherwise specifically defined herein, are
used with the same meaning as defined in the Second Amended and Restated 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; and

     (d) An executed copy of the Second Amended and Restated Credit Agreement and the
Material Subsidiary Guaranty.

     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 is and each Material Subsidiary is 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 with respect to the Company in Otter Tail Corporation’s Annual Report or Form 10-K for
the year ended December 31, 20[_], and (b) enter into and perform its obligations under the Loan
Documents to which it is a party.

     (iii) The execution and delivery by each of the Company and each Material Subsidiary of the
Loan Documents to which it is a party, the borrowing by the Company under the Second Amended and
Restated Credit Agreement, and the performance by each of the Company and each Material Subsidiary
of its 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, as applicable and constitute valid
and binding obligations of the Company and each Material Subsidiary, as applicable, 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 opinion set forth in paragraph (iii) above is subject to the following qualifications and
exceptions:

	 	(i)	 	The opinion set forth in paragraph (iii) above is subject to the effect of any
applicable bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent
transfer, statutes of limitation or other similar laws and judicial decisions affecting
or relating to the rights of creditors generally.
	 
	 	(ii)	 	The opinion set forth in paragraph (iii) above is subject to the effect of
general principles of equity, including without limitation, concepts of materiality,
reasonableness, good faith and fair dealing, estoppel, election of remedies and other
similar doctrines affecting the enforceability of agreements generally (regardless of
whether considered in a proceeding in equity or at law). In addition, the availability
of specific performance, injunctive relief, the appointment of a receiver or other
equitable remedies is subject to the discretion of the tribunal before which any
proceeding therefor may be brought.
	 
	 	(iii)	 	I express no opinion as to the enforceability of provisions in the Loan
Documents to the extent they contain obligations of the Company or any Material
Subsidiary to pay any prepayment premium, default interest rate or other form of
liquidated damages if the payment of such premium, interest rate or damages may be
construed as unreasonable in relation to the actual damages or disproportionate to
actual damages suffered by the party claiming such amounts as a result of such
prepayment or default.
	 
	 	(iv)	 	I express no opinion (A) as to the validity, binding effect or enforceability
of (1) any provision of the Loan Documents related to choice of law, forum selection or
submission to jurisdiction (including, without limitation, any express or implied
waiver of any objection to venue in any court or of any objection that a court is an
inconvenient forum), (2) waivers by the Company or any Material Subsidiary of any
statutory or constitutional rights or remedies, (3) terms which excuse any person or
entity from liability for such person’s or entity’s negligence or willful misconduct,
or (4) cumulative remedies to the extent such cumulative remedies purport to
compensate, or would have the effect of compensating, the party entitled to the
benefits thereof in an amount in excess of the actual loss suffered by such party; or
(B) as to compliance or the effect of noncompliance by you with any state or federal
laws or regulations applicable to you in connection with the transactions described in
the Loan Documents.

 

 

	 	(v)	 	The opinion set forth in paragraph (iii) above with respect to the Material
Subsidiary Guaranty is subject to the defenses available to a guarantor under
applicable law, but the waivers of such defenses set forth in the Material Subsidiary
Guaranty are enforceable, subject to the other exceptions set forth herein.

     I draw your attention to the fact that, under certain circumstances, the enforceability of
terms to the effect that provisions may not be waived or modified except in writing may be limited.

     The opinions expressed above are limited to the laws of the States of Minnesota and North
Dakota and the federal laws of the United States and, with respect to my opinion in paragraphs (i),
(ii) and (iv) only, the following corporate laws: the Arizona Business Corporation Act, the
Delaware General Corporation Law, the Idaho Business Corporation Act, and the General and Business
Corporation Law of Missouri. 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

“Item” herein shall be deemed to refer to such Item on Schedule I hereto),
is made by the party named in Item II, (the “Assignor”) to the entity named in Item
III (the “Assignee”).

WITNESSETH

4, 2010, as amended thereafter (the “Second Amended and Restated Credit Agreement”) among OTTER
TAIL CORPORATION (the “Borrower”), certain lenders including the Assignor (collectively, the “Bank
Group”) and U.S. BANK NATIONAL ASSOCIATION, as Agent, under which the Assignor has agreed to make
Revolving 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 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 Loans are sometimes called the “Loans” hereinafter; such Letters of Credit are sometimes
called the “Letters of Credit” hereinafter; the Loans, the Bank’s participation in the 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, and shall be construed as
set forth in the Second Amended and Restated Credit Agreement.

     In consideration of the premises and the mutual covenants contained herein, the Assignor and
the Assignee hereby covenant and agree as follows:

participations, rights, benefits, obligations, liabilities and indemnities under and in connection
with the Second Amended and Restated 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 obligation to fund all future Advances and drawings under the

with the Second Amended and Restated Credit Agreement.

     The interest of the Assignor under the Second Amended and Restated 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
