request, including the amount requested and such Lender’s Percentage of such
amount. At or before 2:00 p.m. on the date of the Term Loan, each Lender shall
provide the Agent at the principal office of the Agent in Minneapolis, Minnesota

The Borrower shall be obligated to repay the Term Loan notwithstanding the fact
that the person requesting same was not in fact authorized to do

      (a)           Floating Rate Fundings.
Unless the Borrower elects a LIBO Rate pursuant to this Section, the principal
balance of the Notes shall bear interest at the Floating Rate.

       

      (b)           LIBO Rate Fundings. So long
as no Default or Event of Default exists, the Borrower may request that a
portion of the Term Loan constitute a LIBO Rate Funding, or may convert all or
any part of any outstanding Floating Rate Funding into a LIBO Rate Funding, or
may request that a LIBO Rate Funding be converted at the end of the applicable
Interest Period to another LIBO Rate Funding, by giving notice to the Agent of
such request or conversion not later than 10:30 a.m. on a Business Day which is
at least three Business Days prior to the date of the Term Loan or conversion.
Each such notice shall be effective upon receipt by the Agent, shall be in
writing or by telephone or telecopy transmission, shall specify the date and
amount of such LIBO Rate Funding and the Interest Period therefor. The Interest
Period applicable to each LIBO Rate Funding shall begin on a Business Day, and
the amount of each LIBO Rate Funding shall be an integral multiple of $1,000,000
and not less than $10,000,000. Subject to the terms and conditions hereof, the
principal amount specified by the Borrower in the applicable request for a LIBO
Rate Funding shall bear interest from and including the first day of the
Interest Period specified therein to but not including the last day of such
Interest Period, at the LIBO Rate applicable thereto, determined as set forth
herein, (subject to fluctuations in the applicable Margin). Unless the Borrower
requests a new LIBO Rate Funding in accordance with the procedures set forth
above, or prepays the principal of an outstanding LIBO Rate Funding at the
expiration of an Interest Period, the Lenders shall automatically and without
request of the Borrower convert each LIBO Rate Funding to a Floating Rate
Funding on the last day of the relevant Interest Period.

       

      (c)           Setting of LIBO Rates. The
applicable LIBO Rate for each Interest Period shall be determined by the Agent
between the opening of business and 12:00 noon on the second Business Day prior
to the beginning of such Interest Period, whereupon notice thereof (which may be
by telephone) shall be given by the Agent to the Borrower and each Lender. Each
such determination of the applicable LIBO Rate shall be conclusive and binding
upon the parties hereto, in the absence of demonstrable error. The Agent, upon
written request of the Borrower, shall deliver to the Borrower a statement
showing the computations used by the Agent in determining the applicable LIBO
Rate hereunder.

      (d)           Limitations on LIBO Rate
Fundings. In no event shall more than 7 LIBO Rate Fundings be outstanding
at any one time. In no event may the Borrower request a LIBO Rate Funding if,
after giving effect to such LIBO Rate Funding, the Borrower would be required to
prepay a LIBO Rate Funding in order to make any regularly scheduled principal
payment.

2.4                                Principal

on Floating Rate Fundings shall be due and payable on the last day of each
calendar quarter. Interest on any LIBO Rate Funding shall be due and payable on
the last day of the applicable Interest Period or, if such Interest Period is in
excess of three months, on the last day of each three-month period during such
Interest Period and on the last day of such Interest Period.

Date.

      If the
Applicable Ratings established by the Rating Agencies differ such that they do
not fall within a single column in the table set forth above, the Borrower’s
Level Status shall be determined as follows:

       

      
        	
                 
      

              	
                (i)

              	
                If
      the Applicable Ratings applied by any two of the Rating Agencies are in
      the same column, the Borrower’s Level Status shall be determined by that
      column.

              

      

       

      
        	
                 
      

              	
                (ii)

              	
                If
      the Applicable Ratings are each in separate columns, the highest and
      lowest columns shall be excluded, and the Borrower’s Level Status shall be
      determined by the remaining Applicable
Rating.

              

      

       

      
        	
                 
      

              	
                (b)

              	
                In
      making the determinations under paragraph
(a):

              

      

       

      
        	
                 
      

              	
                (i)

              	
                If
      any of the Rating Agencies changes the meaning or designation for its
      Applicable Ratings referenced in paragraph (a), the criteria for Level
      Status in

      the table
in paragraph (a) shall be adjusted in such manner as the Required Lenders may
reasonably determine to correspond with the applicable rating designations used
by the applicable Rating Agency in effect on the date hereof.

       

      
        	
                 
      

              	
                (ii)

              	
                If
      one of the Rating Agencies ceases to rate the Borrower’s long-term
      unsecured debt such that only two of the Rating Agencies are providing
      such Applicable Ratings, the Borrower’s Level Status shall be determined
      as follows:

              

      

       

      
        	
                 
      

              	
                (A)

              	
                If
      the Applicable Ratings provided by both of the remaining Rating Agencies
      are in the same column, the Borrower’s Level Status shall be determined by
      that column.

              

      

       

      
        	
                 
      

              	
                (B)

              	
                If
      the Applicable Ratings provided by the remaining Rating Agencies are in
      adjacent columns, the Borrower’s Level Status shall be based on the
      leftmost of the columns.

              

      

       

      
        	
                 
      

              	
                (C)

              	
                If
      the Applicable Ratings provided by the remaining Rating Agencies are
      separated by one or more columns, the Borrower’s Level Status shall be
      based on the column to the immediate right of the leftmost applicable
      column.

              

      

       

      Notwithstanding
the foregoing, if the Applicable Rating established by either of the remaining
Rating Agencies is in the rightmost column above, the Borrower shall be deemed
to be at Level Status V.

       

      
        	
                 
      

              	
                (iii)

              	
                If
      any two of the Rating Agencies ceases to establish its Applicable Rating,
      the Borrower shall be deemed to be at Level Status
  V.

              

      

       

      (c)           The
Floating Rate Margin and LIBO Rate Margin at any time shall be determined from
time to time on the basis of the Borrower’s Level Status, in accordance with the
following table:

      
        	 
      	
                Level
      I

                0.550%

              	
                0.675%

              	
                0.800%

              	
                1.000%

              

      

       

      (d)           Upon
the occurrence of any Default or Event of Default, and so long as such Default
or Event of Default continues without written waiver thereof by the Lenders, a
default increment equal to 200 basis points (2.00%) shall be added to the
Floating Rate Margin and LIBO Rate Margin. Inclusion of such default increment
shall not be deemed a waiver or excuse of any such Default or Event of
Default.

       

      Section
2.6                                Audit
Fees.

       

      Upon the
occurrence of an Event of Default or at any time thereafter until such Event of
Default is cured, the Borrower shall pay to the Agent, on written demand,
reasonable fees charged by the Agent in connection with any audits or
inspections by the Agent of any collateral or the operations or businesses of
the Borrower, together with actual out-of-pocket costs and expenses incurred in
conducting any such

      
        
           

        

        
          12

          
            

          

        

        
           

        

      

      audit or
inspection. All such audits and inspections shall be for the sole benefit of the
Agent and the Lenders.

       

      Section
2.7                                Prepayments.

       

      (a)           Voluntary Prepayments. The
Borrower from time to time may voluntarily prepay the Notes in whole or in part;
provided that (i) prepayment of any Lender’s Note must be accompanied by
pro rata prepayment of each other Lender’s Note, (ii) any prepayment of the
full amount of any Note shall include accrued interest thereon,
(iii) partial prepayment of any Floating Rate Funding shall be in an
aggregate amount not less than $1,000,000, (iv) partial prepayment of any
LIBO Rate Funding shall be in an aggregate amount not less than $5,000,000, and
(v) any prepayment of any LIBO Rate Funding shall be made only upon three
Business Days’ notice to the Agent.

       

      (b)           Mandatory Prepayment.
Promptly following the receipt thereof, the Borrower shall prepay the
Obligations in an amount equal to 100% of the net proceeds realized by the
Borrower, the Tier 1 Subsidiary or the Tier 2 Subsidiary from (A) debt
obligations incurred by the Borrower, the Tier 1 Subsidiary or the Tier 2
Subsidiary after the date hereof (other than hereunder), or (B) the
issuance by the Borrower, the Tier 1 Subsidiary or the Tier 2 Subsidiary of
Capital Stock; provided, however, that (i) the aggregate amount required to
be paid under this paragraph (b) shall not exceed the then-outstanding
Obligations, and (ii) no prepayment shall be required under this paragraph
(b) on account of the incurrence of approximately $80,000,000 in debt
obligations by the Tier 1 Subsidiary on or about the date hereof for the purpose
of financing the Intermountain Acquisition.

       

      (c)           Application of Prepayments.
So long as no Default or Event of Default has occurred and is continuing
hereunder, all prepayments hereunder shall be applied in such order of
application as the Borrower may direct in writing. In all other cases, all
prepayments hereunder shall be applied in the following order:

       

      
        	
                 
      

              	
                (i)

              	
                First,
      to the principal balance of the
Notes.

              

      

       

      
        	
                 
      

              	
                (ii)

              	
                Second,
      to accrued but unpaid interest on the
Notes.

              

      

       

      
        	
                 
      

              	
                (iii)

              	
                Third,
      to any remaining Obligations, in such order as the Agent may in its sole
      discretion designate.

              

      

       

      Notwithstanding
the foregoing, interest on any LIBO Rate Funding prepaid hereunder and any
compensation due under Section 2.10 on account of prepayment of a LIBO Rate
Funding shall be paid with the same priority as the related principal
prepayment.

       

      Section
2.8                                Payments.

       

      (a)           Making of Payments. All
payments of principal of and interest due under the Notes shall be made to the
Agent at its principal office in Minneapolis, Minnesota, not later than 12:00
noon on the date due, in immediately available funds, and funds received after
that hour shall be deemed to have been received by the Agent on the next
following Business Day. The Borrower hereby authorizes the Agent to charge the
Borrower’s demand deposit account maintained with the Agent for the amount of
any such payment on its due date, all without receipt of any request for such
charge, but the Lender’s failure to so charge such account shall in no way
affect the obligation of the Borrower to make any such payment.

       

      (b)           Assumed Payments. Unless the
Agent has been notified by a Lender or the Borrower prior to the date on which
such Lender or the Borrower is scheduled to make payment

      
        
           

        

        
          13

          
            

          

        

        
           

        

      

      to the
Agent of (in the case of a Lender) its Percentage of the Term Loan or (in the
case of the Borrower) a payment to the Agent for the account of one or more of
the Lenders hereunder (such payment by a Lender or the Borrower (as the case may
be) being herein called a “Required Payment”), which notice shall be effective
upon receipt, that it does not intend to make the Required Payment to the Agent,
the Agent may assume that the Required Payment has been made and may (but shall
not be required to), in reliance upon such assumption, make the amount thereof
available to the intended recipient on such date and, if such Lender or the
Borrower (as the case may be) has not in fact made the Required Payment to the
Agent, the recipient of such payment shall, on demand, repay to the Agent the
amount so made available together with interest thereon for each day during the
period commencing on the date such amount was so made available by the Agent
until the date the Agent recovers such amount at a rate (i) equal to the Federal
Funds Rate for such day, in the case of a Required Payment owing by a Lender, or
(ii) equal to the applicable rate of interest as provided in this Agreement, in
the case of a Required Payment owing by the Borrower.

       

      (c)           Setoff. The Borrower agrees
that each Lender shall have all rights of setoff and bankers’ lien provided by
applicable law, and in addition thereto, the Borrower agrees that if at any time
any amount is due and owing by the Borrower under this Agreement to any Lender
at a time when an Event of Default has occurred and is continuing hereunder, any
Lender may apply any and all balances, credits, and deposits, accounts or moneys
of the Borrower then or thereafter in the possession of that Lender (excluding,
however, any trust or escrow accounts held by the Borrower for the benefit of
any third party) to the payment thereof.

       

      (d)           Due Date Extension. If any
payment of principal of or interest on any Floating Rate Funding or any fees
payable hereunder falls due on a day which is not a Business Day, then such due
date shall be extended to the next following Business Day, and (in the case of
principal) additional interest shall accrue and be payable for the period of
such extension.

       

      (e)           Application of Payments.
Except as otherwise provided herein, so long as no Default or Event of Default
has occurred and is continuing hereunder, each payment received from the
Borrower shall be applied to such obligation as the Borrower shall specify by
notice received by the Agent on or before the date of such payment, or in the
absence of such notice, as the Required Lenders shall determine in their
discretion. Except as otherwise provided herein, after the occurrence of a
Default or Event of Default, the Lenders shall have the right to apply all
payments received by the Lender from the Borrower as the Required Lenders may
determine in their discretion. The Borrower agrees that the amount shown on the
books and records of the Agent and the Lenders as being the principal balance of
and interest on the Notes shall be conclusive absent demonstrable
error.

       

      Section
2.9                                Increased
Costs; Funding Exceptions.

       

      (a)           Increased Costs on LIBO Rate
Fundings. If Regulation D of the Board of Governors of the Federal
Reserve System or after the date of this Agreement the adoption of any
applicable law, rule or regulation, or any change in any existing law, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency, shall:

       

      
        	
                 
      

              	
                (i)

              	
                subject
      that Lender to or cause the withdrawal or termination of any exemption
      previously granted to that Lender with respect to, any tax, duty or other
      charge with respect to its LIBO Rate Fundings or its obligation to make
      LIBO Rate

              

      

      
        
           

        

        
          14

          
            

          

        

        
           

        

      

      Fundings,
or shall change the basis of taxation of payments to that Lender of the
principal of or interest under this Agreement in respect of its LIBO Rate
Fundings or its obligation to make LIBO Rate Fundings (except for changes in the
rate of tax on the overall net income of that Lender imposed by the
jurisdictions in which that Lender’s principal executive office is located);
or

       

      
        	
                 
      

              	
                (ii)

              	
                impose,
      modify or deem applicable any reserve (including, without limitation, any
      reserve imposed by the Board of Governors of the Federal Reserve System,
      but excluding any reserve included in the determination of interest rates
      pursuant to Section 2.3), special deposit or similar requirement against
      assets of, deposits with or for the account of, or credit extended by,
      that Lender; or

              

      

       

      
        	
                 
      

              	
                (iii)

              	
                impose
      on that Lender any other condition affecting its making, maintaining or
      funding of its LIBO Rate Fundings or its obligation to make LIBO Rate
      Fundings;

              

      

       

      and the
result of any of the foregoing is to increase the cost to that Lender of making
or maintaining any LIBO Rate Funding, or to reduce the amount of any sum
received or receivable by that Lender under this Agreement or under its Notes
with respect to a LIBO Rate Funding, then that Lender will notify the Borrower
of such increased cost and within fifteen (15) days after demand by that Lender
(which demand shall be accompanied by a statement setting forth the basis of
such demand and representing that that Lender has made similar demand on one or
more other commercial borrowers with revolving or term loans in excess of
$1,000,000) the Borrower shall pay to that Lender such additional amount or
amounts as will compensate that Lender for such increased cost or such
reduction; provided, however, that no such increased cost or such reduction
shall be payable by the Borrower for any period longer than ninety (90) days
prior to the date on which notice thereof is delivered to the Borrower. Each
Lender will promptly notify the Borrower of any event of which it has knowledge,
occurring after the date hereof, which will entitle that Lender to compensation
pursuant to this Section 2.9. If the Borrower receives notice from any Lender of
any event which will entitle that Lender to compensation pursuant to this
Section 2.9, the Borrower may prepay any then outstanding LIBO Rate Fundings or
notify that Lender that any pending request for a LIBO Rate Funding shall be
deemed to be a request for a Floating Rate Funding, in each case subject to the
provisions of Section 2.10.

       

      (b)           Basis for Determining Interest Rate
Inadequate or Unfair. If with respect to any Interest
Period:

       

      
        	
                 
      

              	
                (i)

              	
                any
      Lender determines that deposits in U.S. dollars (in the applicable
      amounts) are not being offered in the London interbank eurodollar market
      for such Interest Period; or

              

      

       

      
        	
                 
      

              	
                (ii)

              	
                any
      Lender otherwise determines that by reason of circumstances affecting the
      London interbank eurodollar market adequate and reasonable means do not
      exist for ascertaining the applicable LIBO Rate;
  or

              

      

       

      
        	
                 
      

              	
                (iii)

              	
                any
      Lender determines that the LIBO Rate as determined by the Agent will not
      adequately and fairly reflect the cost to that Lender of maintaining or
      funding a LIBO Rate Funding for such Interest Period, or that the making
      or funding of LIBO Rate Fundings has become impracticable as a result of
      an event occurring after the date of this Agreement which in the opinion
      of that Lender materially affects such LIBO Rate
  Fundings;

      then that
Lender shall promptly notify the Borrower and (A) upon the occurrence of any
event described in the foregoing clause (i) the Borrower shall enter into good
faith negotiations with that Lender in order to determine an alternate method to
determine the LIBO Rate for that Lender, and during the pendency of such
negotiations with that Lender, the Lenders shall be under no obligation to make
any new LIBO Rate Fundings, and (B) upon the occurrence of any event described
in the foregoing clauses (ii) or (iii), for so long as such circumstances shall
continue, the Lenders shall be under no obligation to make any new LIBO Rate
Fundings.

       

      (c)           Illegality. If any change in
(including the adoption of any new) applicable laws or regulations, or any
change in the interpretation of applicable laws or regulations by any
governmental authority, central bank, comparable agency or any other regulatory
body charged with the interpretation, implementation or administration thereof,
or compliance by any Lender with any request or directive (whether or not having
the force of law) of any such authority, central bank, comparable agency or
other regulatory body, should make it or, in the good faith judgment of that
Lender, shall raise a substantial question as to whether it is unlawful for that
Lender to make, maintain or fund LIBO Rate Fundings, then (i) that Lender shall
promptly notify the Borrower and the Agent, (ii) the obligation of the Lenders
to make, maintain or convert into LIBO Rate Fundings shall, upon the
effectiveness of such event, be suspended for the duration of such unlawfulness,
and (iii) for the duration of such unlawfulness, any notice by the Borrower
requesting the Lenders to make or convert into LIBO Rate Fundings shall be
construed as a request to make or to continue making Floating Rate
Fundings.

       

      Section
2.10                                Funding
Losses.

       

      Upon
demand by any Lender (which demand shall be accompanied by a statement setting
forth the basis for the calculations of the amount being claimed), the Borrower
shall indemnify that Lender against any loss or expense which that Lender may
have sustained or incurred (including, without limitation, any net loss or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by that Lender to fund or maintain LIBO Rate Fundings) or
which that Lender may be deemed to have sustained or incurred, as reasonably
determined by that Lender, (i) as a consequence of any failure by the Borrower
to make any payment when due of any amount due hereunder in connection with any
LIBO Rate Fundings, (ii) due to any failure of the Borrower to borrow or convert
any LIBO Rate Fundings on a date specified therefor in a notice thereof or (iii)
due to any payment or prepayment of any LIBO Rate Funding on a date other than
the last day of the applicable Interest Period for such LIBO Rate Funding. For
this purpose, all notices under Section 2.3(b) shall be deemed to be
irrevocable.

       

      Section
2.11                                Discretion
of Lenders as to Manner of Funding.

       

      Notwithstanding
any provision of this Agreement to the contrary, each Lender shall be entitled
to fund and maintain all or any part of its LIBO Rate Fundings in any manner it
deems fit, it being understood, however, that for the purposes of this Agreement
(specifically including, without limitation, Section 2.10 hereof) all
determinations hereunder shall be made as if that Lender had actually funded and
maintained each LIBO Rate Funding during each Interest Period for such LIBO Rate
Funding through the purchase of deposits having a maturity corresponding to such
Interest Period and bearing an interest rate equal to the appropriate LIBO Rate
for such Interest Period.

       

      Section
2.12                                Conclusiveness
of Statements; Survival of Provisions.

       

      Determinations
and statements of any Lender pursuant to Sections 2.9 and 2.10 shall be
conclusive absent demonstrable error. Without limiting the generality of the
foregoing, the Borrower shall have no right to review any records of any Lender
or its other customers to determine the accuracy of any statement by that Lender
under Section 2.9(a) regarding that Lender’s demands upon other customers
of that Lender.  Each Lender may use reasonable averaging and
attribution methods in determining compensation

survive termination of this Agreement.

of Interest and Fees.

       

      All
interest determined at the Floating Rate will be calculated based on the actual
days elapsed in a year of 365 or 366 days, as the case may be. All interest
determined at the LIBO Rate and all fees hereunder shall be computed on the
basis of actual number of days elapsed in a year of 360 days.

      Section
4.1                                Existence
and Power.

       

      The
Borrower is a corporation duly incorporated, validly existing and in good
standing under the laws of Delaware, and is duly licensed or qualified to
transact business in all jurisdictions where the character of the property owned
or leased or the nature of the business transacted by it makes such licensing or
qualification necessary, except where the failure to be so licensed or qualified
(i) will not permanently preclude the Borrower from maintaining any
material action in any such jurisdiction even though such action arose in whole
or in part during the period of such failure, and (ii) will not result in
any other Material Adverse Effect. The Borrower has all requisite power and
authority, corporate or otherwise, to conduct its business, to own its
properties and to execute and deliver, and to perform all of its obligations
under, the Loan Documents.

       

      Section
4.2                                Authorization
of Borrowing; No Conflict as to Law or Agreements.

       

      The
execution, delivery and performance by the Borrower of the Loan Documents and
the borrowing hereunder have been duly authorized by all necessary corporate
action and by all necessary public utilities commissions and any other
regulatory bodies having jurisdiction over the Borrower, and do not and will not
(i) require any consent or approval of the stockholders of the Borrower, or
any authorization, consent or approval by any governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign, other
than Authorizing Orders set forth in Schedule 4.2 that have been obtained and
copies of which have been delivered to the Agent pursuant to Section 3.1,
(ii) violate any provision of any law, rule or regulation (including,
without limitation, Regulation X of the Board of Governors of the Federal
Reserve System) or of any order, writ, injunction or decree presently in effect
having applicability to the Borrower or of the articles of incorporation or
bylaws of the Borrower, (iii) result in a breach of or constitute a default
under any indenture or loan or credit agreement or any other agreement, lease or
instrument to which the Borrower is a party or by which it or its properties may
be bound or affected, or (iv) result in, or require, the creation or
imposition of any Lien or other charge or encumbrance of any nature (other than
those in favor of the Agent to secure one or more of the Obligations) upon or
with respect to any of the properties now owned or hereafter acquired by the
Borrower.

      

      Section
4.3                                Legal
Agreements.

       

      This
Agreement and the other Loan Documents constitute the legal, valid and binding
obligations of the Borrower enforceable against the Borrower in accordance with
their respective terms, except to the extent that such enforcement may be
limited by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors’ rights generally or by general equitable principles.

      Schedule
4.4 hereto is a complete and correct list of all present Subsidiaries and of the
percentage of the ownership of the Borrower or any other Subsidiary in each case
as of the date of this Agreement. Except as otherwise indicated in that
Schedule, all shares of each Subsidiary owned by the Borrower or by any such
other Subsidiary are validly issued and fully paid and
nonassessable.

       

      Section
4.5                                Financial
Condition.

       

      The
Borrower has heretofore furnished to the Lenders its audited consolidated
financial statement as of December 31, 2007, and its unaudited interim financial
statement as of June 30, 2008. Those financial statements fairly present the
financial condition of the Borrower and its Subsidiaries on the dates thereof
and the results of their operations and cash flows for the periods then ended,
and were prepared in accordance with GAAP, except as expressly noted
therein.

       

      Section
4.6                                Adverse
Change.

       

      There has
been no material adverse change in the business, properties or condition
(financial or otherwise) of the Borrower since the date of the latest financial
statement referred to in Section 4.5.

       

      Section
4.7                                Litigation.

       

      Except as
set forth in the Borrower’s Annual Report on Form 10-K for the year ended
December 31, 2007, or in any document subsequently filed pursuant to Section 13,
14 or 15(d) of the Exchange Act, there are no actions, suits or proceedings
pending or, to the knowledge of the Borrower, threatened against or affecting
the Borrower or the properties of the Borrower, before any court or governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign, which, if determined adversely to the Borrower, would have a Material
Adverse Effect.

       

      Section
4.8                                Environmental
Matters.

       

      The
Borrower conducts in the ordinary course of business a review of the effect of
existing Environmental Laws and existing Environmental Claims on its business,
operations and properties and, as a result thereof, the Borrower has reasonably
concluded that such Environmental Laws and Environmental Claims could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, exclusive of Environmental Claims as set forth in the Borrower’s
Annual Report on Form 10-K for the year ended December 31, 2007, or in any
document subsequently filed pursuant to Section 13, 14 or 15(d) of the Exchange
Act.

       

      Section
4.9                                Regulation
U.

       

      The
Borrower is not engaged in the business of extending credit for the purpose of
purchasing or carrying margin stock (within the meaning of Regulation U of the
Board of Governors of the Federal Reserve System), and no part of the proceeds
of the Term Loan will be used to purchase or carry any margin stock or to extend
credit to others for the purpose of purchasing or carrying any margin
stock.

       

      Section
4.10                                Taxes.

       

      The
Borrower has filed all federal and other tax returns and reports required to be
filed, and has paid all federal and other taxes, assessments, fees and other
governmental charges levied or imposed upon it or its properties, income or
assets otherwise due and payable, except those which are being contested in good
faith by appropriate proceedings and for which adequate reserves have been
provided in accordance with GAAP and except those the failure to file or pay
which would not have a Material Adverse Effect. There is no proposed tax
assessment against the Borrower that would, if made, have a Material Adverse
Effect.

      Section
4.11                                Titles
and Liens.

       

      To the
Borrower’s knowledge, without having undertaken any search of real property
records for this purpose, the Borrower has good and sufficient title to, or
valid leasehold interests in, all real property necessary or used in the
ordinary conduct of its business, and good title to all other property and
assets reflected in the Borrower’s most recent consolidated financial statements
provided to the Lenders as owned by the Borrower, except for such defects in
title as could not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect and other than any sold, as permitted by Section
6.4. As of the date of this Agreement, the property of the Borrower is subject
to no Liens other than a permitted pursuant to Section 6.1.

       

      Section
4.12                                Intellectual
Property.

       

      The
Borrower owns or is licensed or otherwise has the right to use all of the
patents, trademarks, service marks, trade names, copyrights, contractual
franchises, authorizations and other rights that are reasonably necessary for
the operation of its business, without conflict with the rights of any other
Person, except to the extent that noncompliance would not have a Material
Adverse Effect. To the knowledge of the Borrower, no slogan or other advertising
device, product, process, method, substance, part or other material now
employed, or now contemplated to be employed, by the Borrower infringes upon any
rights held by any other Person, except to the extent that noncompliance would
not have a Material Adverse Effect. No claim or litigation regarding any of the
foregoing is pending or threatened, and no patent, invention, device,
application, principle or any statute, law, rule, regulation, standard or code
is pending or, to the knowledge of the Borrower, proposed, which, in either
case, could reasonably be expected to have a Material Adverse
Effect.

       

      Section
4.13                                ERISA.

       

      (a)           Each
Plan is in compliance in all material respects with ERISA, the Code and other
applicable federal or state law. Each Plan which is intended to qualify under
Section 401(a) of the Code has received a favorable determination letter from
the Internal Revenue Service and, to the best knowledge of the Borrower, nothing
has occurred which would or could reasonably be expected to cause the loss
of such
qualification of any such Plan or
related trust.

       

      (b)           There
are no pending or, to the best knowledge of the Borrower,
threatened claims (other than routine claims for benefits in the ordinary
course), actions or lawsuits, or action by any governmental authority, with
respect to any Plan which has resulted or could reasonably be expected to result
in a Material Adverse Effect. To the best knowledge of the Borrower, there has
been no prohibited transaction within the meaning of Section 4975 of the Code or
Section 406 ERISA or other material violation of the fiduciary responsibility
rules with respect to any Plan which has resulted or could reasonably be
expected to result in a Material Adverse Effect.

       

      (c)           No
Reportable Event has occurred or is reasonably expected to occur with respect to
any Pension Plan.

       

      (d)           The
aggregate Unfunded Pension Liability for all Pension Plans (calculated based on
the most recent actuarial report for each Pension Plan) does not exceed
$25,000,000.

       

      (e)           Neither
the Borrower nor any ERISA Affiliate has incurred nor does it reasonably expect
to incur, any liability under Title IV of ERISA with respect to any Pension Plan
(other than premiums due and not delinquent under Section 4007 of
ERISA).

      (f)           Neither
the Borrower nor any ERISA Affiliate has transferred any Unfunded Pension
Liability to any Person or otherwise engaged in a transaction that could be
subject to Section 4069 of ERISA.

       

      (g)           Neither
the Borrower nor any ERISA Affiliate has incurred nor reasonably expects to
incur any liability, other than Acquisition Liability (and no event has occurred
which, with the giving of notice under Section 4219 of ERISA, would result in
such liability), under Section 4201 or 4243 of ERISA with respect to a
Multiemployer Plan. As used in this paragraph, “Acquisition Liability” means
liability immaterial to the Borrower, its business and operations when taken as
a whole that is incurred in connection with an acquisition by the Borrower or
any ERISA Affiliate.

7.1                                Events
of Default.

       

      “Event of
Default”, wherever used herein, means any one of the following
events:

       

      (a)           Default
in the payment of any principal of any Note when it becomes due and
payable.

       

      (b)           Default
in the payment of any interest on any Note when the same becomes due and payable
and the continuance of such default for a period of two calendar days; or
default in the payment of any fees required under Section 2.6 when the same
become due and payable and the continuance of such default for a period of five
calendar days.

       

      (c)           Default
in the performance, or breach, of any covenant or agreement on the part of the
Borrower contained in Article VI.

       

      (d)           Default
in the performance, or breach, of any covenant or agreement of the Borrower in
this Agreement (other than a covenant or agreement a default in whose
performance or whose breach is elsewhere in this Section specifically dealt
with), and the continuance of such default or breach for a period of 30 days
after the Lenders have given notice to the Borrower specifying such default or
breach and requiring it to be remedied.

       

      (e)           Any
representation or warranty made by the Borrower in this Agreement or by the
Borrower (or any of its officers) in any certificate, instrument, or statement
contemplated by or made or delivered pursuant to or in connection with this
Agreement, shall prove to have been incorrect or misleading in any material
respect when made.

       

      
        (f)           An
Event of Default, as defined in the 2005 Credit Agreement, shall
occur.

      

      
        
           

        

        
          27

          
            

          

        

        
           

        

      

       

      (g)           A
default under either Mortgage Indenture or with respect to any other Funded Debt
(other than any default dealt with elsewhere in this Section) and the expiration
of the applicable period of grace, if any, specified in the applicable evidence
of indebtedness, indenture or other instrument; provided, however, that no Event
of Default shall be deemed to have occurred under this paragraph if the
aggregate amount owing as to all such indebtedness as to which such defaults
have occurred and are continuing is less than $15,000,000; provided further that
if such default shall be cured by the Borrower, or waived by the holders of such
indebtedness, in each case prior to the commencement of any action under Section
7.2 and as may be permitted by such evidence of indebtedness, indenture or other
instrument, then the Event of Default hereunder by reason of such default shall
be deemed likewise to have been thereupon cured or waived.

       

      (h)           The
Borrower (i) ceases or fails to be Solvent, or generally fails to pay, or admits
in writing its inability to pay, its debts as they become due, subject to
applicable grace periods, if any, whether at stated maturity or otherwise;
(ii) voluntarily ceases to conduct its business in the ordinary course;
(iii) commences any Insolvency Proceeding with respect to itself; or (iv) takes
any action to effectuate or authorize any of the foregoing.

       

      (i)           (i) Any
involuntary Insolvency Proceeding is commenced or filed against the Borrower, or
any writ, judgment, warrant of attachment, execution or similar process is
issued or levied against a substantial part of the Borrower’s properties, and
any such proceeding or petition shall not be dismissed, or such writ, judgment,
warrant of attachment, execution or similar process shall not be released,
vacated or fully bonded within 60 days after commencement, filing or levy; or
(ii) the Borrower admits the material allegations of a petition against it
in any Insolvency Proceeding, or an order for relief (or similar order under
non-U.S. law) is ordered in any Insolvency Proceeding; or (iii) the
Borrower acquiesces in the appointment of a receiver, trustee, custodian,
conservator, liquidator, mortgagee in possession (or agent therefor), or similar
Person for itself or a substantial portion of its property or
business.

       

      (j)           A
Change of Control shall occur with respect to the Borrower.

       

      (k)           The
Borrower shall fail within 45 days to pay, bond or otherwise discharge any
judgment or order for the payment of money in excess of $10,000,000, which is
not stayed on appeal or otherwise being appropriately contested in good
faith.

       

      (l)           (i) An
ERISA Event or ERISA Termination Event which has resulted or would reasonably be
expected to result in liability of the Borrower under Title IV of ERISA to the
Pension Plan, Multiemployer Plan or the PBGC in an aggregate amount in excess of
10% of Consolidated Net Worth; (ii) the commencement or increase of
contributions to, or the adoption of or the amendment of, a Pension Plan by the
Borrower or an ERISA Affiliate which has resulted or could reasonably be
expected to result in an increase in Unfunded Pension Liability among all
Pension Plans in an aggregate amount in excess of 10% of Consolidated Net Worth;
or (iii) the Borrower’s or an ERISA Affiliate’s failure to pay when due, after
the expiration of any applicable grace period, any installment payment with
respect to its withdrawal liability under Section 4201 of ERISA under a
Multiemployer Plan which has resulted or could reasonably be expected to result
in a Material Adverse Effect.

       

      (m)           Any
governmental authority or other administrative or legal authority having
regulatory jurisdiction over the Borrower takes any action which has a Material
Adverse Effect on the Borrower.

      Section
7.2                                Rights
and Remedies.

       

      Upon the
occurrence of an Event of Default or at any time thereafter until such Event of
Default is cured to the written satisfaction of the Required Lenders, the Agent
may, with the consent of the Required Lenders, and shall, at the request of the
Required Lenders, exercise any or all of the following rights and
remedies:

       

      (a)           If
the Term Loan has not been advanced, the Agent may, by notice to the Borrower,
declare the Commitments to be terminated, whereupon the same shall forthwith
terminate.

       

      (b)           The
Agent may, by notice to the Borrower, declare the entire unpaid principal amount
of the Notes then outstanding, all interest accrued and unpaid thereon, and all
other Obligations to be forthwith due and payable, whereupon the Notes, all such
accrued interest and all such other Obligations shall become and be forthwith
due and payable, without presentment, demand, protest or further notice of any
kind, all of which are hereby expressly waived by the Borrower.

       

      (c)           The
Lenders may exercise any other rights and remedies available to them by law or
agreement.

       

      Notwithstanding
the foregoing, upon the occurrence of an Event of Default described in Section
7.1(h) or 7.1(i) hereof, the entire unpaid principal amount of the Notes then
outstanding, all interest accrued and unpaid thereon, and all other amounts
payable under this Agreement shall be immediately due and payable without
presentment, demand, protest or notice of any kind.

      The
Agent

       

      Section
8.1                                Authorization.

       

      Each
Lender and the holder of each Note irrevocably appoints and authorizes the Agent
to act on behalf of such Lender or holder to the extent provided herein or in
any document or instrument delivered hereunder or in connection herewith, and to
take such other action as may be reasonably incidental thereto. In furtherance
of the foregoing, and not in limitation thereof, each Lender irrevocably
(i) authorizes the Agent to execute and deliver and perform its obligations
under this Agreement and each of the Loan Documents to which the Agent is a
party, and to exercise all rights, powers and remedies that the Agent may have
hereunder or thereunder, (ii) appoints the Agent as nominal beneficiary or
nominal secured party, as the case may be, under the Loan Documents and all
related UCC-1 financing statements, and (iii) authorizes the Agent to act
as agent of and for such Lender for purposes of holding, perfecting and
disposing of any collateral under the Loan Documents. As to any matters not
expressly provided for by this Agreement or the Loan Documents, the Agent shall
not be required to exercise any discretion or take any action, but shall be
required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of the Required Lenders
or, if so required pursuant to Section 9.2, upon the instructions of all
Lenders; provided, however, that except for action expressly required of the
Agent hereunder, the Agent shall in all cases be fully justified in failing or
refusing to act hereunder unless it shall be indemnified to its satisfaction by
the Lenders against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action, and the Agent
shall not in any event be required to take any action which is contrary to this
Agreement, the Loan Documents or applicable law. The Agent shall not have a
fiduciary relationship in respect of the Borrower or any Lender by reason of
this Agreement.

      Section
8.2                                Distribution
of Payments and Proceeds.

       

      (a)           After
deduction of any costs of collection, as provided in this Agreement and the
other Loan Documents, and any fee payable to the Agent in its capacity as such
under this Agreement or any other agreement, the Agent shall remit to each
Lender that Lender’s Percentage of all payments of principal and interest and of
all fees and other amounts payable hereunder for the benefit of the Lenders that
are received by the Agent under the Loan Documents. Each Lender’s interest in
the Loan Documents shall be payable solely from payments, collections and
proceeds actually received by the Agent under the Loan Documents; and the
Agent’s only liability to the Lenders hereunder shall be to account for each
Lender’s Percentage of such payments, collections and proceeds in accordance
with this Agreement. If the Agent is ever required for any reason to refund any
such payments, collections or proceeds, each Lender will refund to the Agent,
upon demand, its Percentage of such payments, collections or proceeds, together
with its Percentage of interest or penalties, if any, payable by the Agent in
connection with such refund.

       

      (b)           Notwithstanding
the foregoing, if any Lender has wrongfully refused to fund its Percentage of
the Term Loan as required hereunder, or if the principal balance of any Lender’s
Note is for any other reason less than its Percentage of the aggregate principal
balances of the Notes then outstanding, the Agent may remit all payments
received by it to the other Lenders until such payments have reduced the
aggregate amounts owed by the Borrower to the extent that the aggregate amount
owing to such Lender hereunder is equal to its Percentage of the aggregate
amount owing to all of the Lenders hereunder. The provisions of this paragraph
are intended only to set forth certain rules for the application of payments,
proceeds and collections in the event that a Lender has breached its obligations
hereunder and shall not be deemed to excuse any Lender from such
obligations.

       

      Section
8.3                                Expenses.

       

      All
payments, collections and proceeds received or effected by the Agent may be
applied, first, to pay or reimburse the Agent for all costs, expenses, damages
and liabilities at any time incurred by or imposed upon the Agent in connection
with this Agreement or any other Loan Document (including but not limited to all
reasonable attorney’s fees, foreclosure expenses and advances made to protect
the security of any collateral). If the Agent does not receive payments,
collections or proceeds sufficient to cover any such costs, expenses, damages or
liabilities within 30 days after their incurrence or imposition, each Lender
shall, upon demand, remit to the Agent its Percentage of the difference between
(i) such costs, expenses, damages and liabilities, and (ii) such payments,
collections and proceeds, together with interest on such amount for each day
following the thirtieth day after demand therefor until so remitted at a rate
equal to the Federal Funds Rate for each such day.

       

      Section
8.4                                Payments
Received Directly by Lenders.

       

      If any
Lender or other holder of a Note shall obtain any payment or other recovery
(whether voluntary, involuntary, by application of offset or otherwise) on
account of the Obligations other than through distributions made in accordance
with Section 8.2, such Lender or holder shall promptly give notice of such fact
to the Agent and shall purchase from the other Lenders or holders such
participations in the Obligations held by them as shall be necessary to cause
the purchasing Lender or holder to share the excess payment or other recovery
ratably with each of them; provided, however, that if all or any portion of the
excess payment or other recovery is thereafter recovered from such purchasing
Lender or holder, the purchase shall be rescinded and the purchasing Lender
restored to the extent of such recovery (but without interest
thereon).

      Section
8.5                                Indemnification.

       

      Each
Lender severally (but not jointly) hereby agrees to indemnify and hold harmless
the Agent, as well as the Agent’s agents, employees, officers and directors,
ratably according to their respective Percentages from and against any and all
losses, liabilities (including liabilities for penalties), actions, suits,
judgment, demands, damages, costs, disbursements, or expenses (including
attorneys’ fees and expenses) of any kind or nature whatsoever, which are
imposed on, incurred by, or asserted against the Agent or its agents, employees,
officers or directors in any way relating to or arising out of this Agreement or
the Loan Documents, or as a result of any action taken or omitted to be taken by
the Agent; provided, however, that no
Lender shall be liable for any portion of any such losses, liabilities
(including liabilities for penalties), actions, suits, judgments, demands,
damages, costs disbursements, or expenses resulting from the gross negligence or
willful misconduct of the Agent. Notwithstanding any other provision of the Loan
Documents, the Agent shall in all cases be fully justified in failing or
refusing to act hereunder unless it shall be indemnified to its satisfaction by
the Lenders against any and all liability and expense that may be incurred by it
by reason of taking or continuing to take any such action.

       

      Section
8.6                                Exculpation.

       

      The Agent
shall not be liable for any action taken or omitted to be taken by the Agent in
connection with this Agreement or the Loan Documents, except for its own gross
negligence or willful misconduct. The Agent shall be entitled to rely upon
advice of counsel concerning legal matters, the advice of independent public
accountants with respect to accounting matters and advice of other experts as to
any other matters, and upon this Agreement, any Loan Document and any schedule,
certificate, statement, report, notice or other writing which it believes to be
genuine or to have been presented by a proper person. Neither the Agent nor any
of its directors, officers, employees or agents shall (a) be responsible for any
recitals, representations or warranties contained in, or for the execution,
validity, genuineness, effectiveness or enforceability of this Agreement, any
Loan Document, or any other instrument or document delivered hereunder or in
connection herewith, (b) be responsible for the validity, genuineness,
perfection, effectiveness, enforceability, existence, value or enforcement of
any collateral security, (c) be under any duty to inquire into or pass upon any
of the foregoing matters, or to make any inquiry concerning the performance by
the Borrower or any other obligor of its obligations, or (d) in any event, be
liable as such for any action taken or omitted by it or them, except for its or
their own gross negligence or willful misconduct. The agency hereby created
shall in no way impair or affect any of the rights and powers of, or impose any
duties or obligations upon, the Agent in its individual capacity.

       

      Section
8.7                                Agent
and Affiliates.

       

      The Agent
shall have the same rights and powers hereunder in its individual capacity as
any other Lender, and may exercise or refrain from exercising the same as though
it were not the Agent, and the Agent and its affiliates may accept deposits from
and generally engage in any kind of business with the Borrower as fully as if
the Agent were not the Agent hereunder.

       

      Section
8.8                                Credit
Investigation.

       

      Each
Lender acknowledges that it has made such inquiries and taken such care on its
own behalf as would have been the case had its obligations hereunder been
incurred and its Percentage of the Term Loan made directly by such Lender to the
Borrower without the intervention of the Agent or any other Lender. Each Lender
agrees and acknowledges that the Agent makes no representations or warranties
about the creditworthiness of the Borrower or any other party to this Agreement
or with respect to the legality, validity, sufficiency or enforceability of this
Agreement, any Loan Document, or any other instrument or document delivered
hereunder or in connection herewith.

      Section
8.9                                Resignation
and Assignment of Agent.

       

      (a)           The
Agent may resign as such at any time upon at least 30 days’ prior notice to the
Borrower and the Lenders. In the event of any resignation of the Agent, the
Required Lenders shall as promptly as practicable appoint a successor Agent. If
no such successor Agent shall have been so appointed by the Required Lenders and
shall have accepted such appointment within 30 days after the resigning Agent’s
giving of notice of resignation, then the resigning Agent may, on behalf of the
Lenders, appoint a successor Agent, which shall be a commercial bank organized
under the laws of the United States of America or of any State thereof. Any such
successor Agent shall have capital and retained earnings of at least
$100,000,000.

       

      (b)           The
Agent may, without the consent of the Borrower or the other Lenders, assign its
rights and obligations as Agent hereunder and under the other Loan Documents to
its parent or to any wholly owned subsidiary of its parent, and upon such
assignment, the former Agent shall be deemed to have retired, and such wholly
owned subsidiary shall be deemed to be a successor Agent. Any such successor
Agent shall have capital and retained earnings of at least
$100,000,000.

       

      (c)           Upon
the acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon be entitled to receive from the prior Agent such
documents of transfer and assignment as such successor Agent may reasonably
request and the resigning or assigning Agent shall be discharged from its duties
and obligations under this Agreement. After any resignation or assignment
pursuant to this Section, the provisions of this Section shall inure to the
benefit of the retiring Agent as to any actions taken or omitted to be taken by
it while it was acting as Agent hereunder.

       

      Section
8.10                                Defaults.

       

      The Agent
shall not be deemed to have knowledge of the occurrence of a Default or an Event
of Default unless the Agent has received notice from a Lender or the Borrower
specifying the occurrence of such Default or Event of Default. In the event that
the Agent receives such a notice of the occurrence of a Default or an Event of
Default, the Agent shall give prompt notice thereof to the Lenders. The Agent
shall (subject to Section 8.5 hereof) take such actions with respect to such
Default as shall be directed by the Required Lenders; provided that, unless and
until the Agent shall have received such directions, the Agent may take any
action, or refrain from taking any action, with respect to such Default as it
shall deem advisable in the best interest of the Lenders.

       

      Section
8.11                                Obligations
Several.

       

      The
obligations of each Lender hereunder are the several obligations of such Lender,
and neither any Lender nor the Agent shall be responsible for the obligations of
any other Lender hereunder, nor will the failure by the Agent or any Lender to
perform any of its obligations hereunder relieve the Agent or any other Lender
from the performance of its respective obligations hereunder. Nothing contained
in this Agreement, and no action taken by any Lender or the Agent pursuant
hereto or in connection herewith or pursuant to or in connection with the Loan
Documents shall be deemed to constitute the Lenders, together or with or without
the Agent, as a partnership, association, joint venture, or other
entity.

other or further exercise thereof or the exercise of any other right, power or
remedy under the Loan Documents. The remedies provided in the Loan Documents are
cumulative and not exclusive of any remedies provided by law.

amendment or waiver of any provision of any Loan Document or consent to any
departure by the Borrower therefrom shall be effective unless the same shall be
in writing and signed by the Required Lenders (or by the Agent with the consent
or at the request of the Required Lenders), and any such waiver shall be
effective only in the specific instance and for the specific purpose for which
given. No notice to or demand on the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances.

      this Section, the definition of “Required Lenders” in Section 1.1, or any
      provision herein providing for consent or other action by all
      Lenders.

              

      

       

      (b)           No
such amendment or waiver shall be effective to do any of the following unless
signed by each of the Lenders affected thereby (or by the Agent with the consent
or at the request of each of such Lenders):

       

      
        	
                 
      

              	
                 (i)

      Section
9.4                                Costs
and Expenses.

       

      The
Borrower agrees to pay on demand all reasonable costs and expenses incurred by
the Agent in connection with the negotiation, preparation, execution,
administration, amendment or enforcement of the Loan Documents and the other
instruments and documents to be delivered hereunder and thereunder, including
the reasonable fees and out-of-pocket expenses of counsel for any Lender with
respect thereto, whether paid to outside counsel or allocated to the Agent by
in-house counsel.

       

      Section
9.5                                Indemnification
by Borrower.

       

      The
Borrower hereby agrees to indemnify the Agent and the Lenders and each officer,
director, employee and agent thereof (herein individually each called an
“Indemnitee” and collectively called the “Indemnitees”) from and against any and
all losses, claims, damages, reasonable expenses (including, without limitation,
reasonable attorneys’ fees) and liabilities incurred by an Indemnitee in
connection with or arising out of the execution or delivery of this Agreement or
any agreement or instrument contemplated hereby, the performance by the parties
hereto of their respective obligations hereunder or the use of the proceeds of
the Term Loan (including but not limited to any such loss, claim, damage,
expense or liability arising out of any claim in which it is alleged that any
Environmental Law has been breached with respect to any activity or property of
the Borrower), except to the extent that such loss, claim, damage, expense or
liability was incurred as a result of the gross negligence or willful misconduct
of the applicable Indemnitee. All obligations provided for in this
Section shall survive any termination of this Agreement.

       

      Section
9.6                                Execution
in Counterparts.

       

      This
Agreement and the other Loan Documents may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed to be
an original and all of which counterparts of this Agreement or such other Loan
Document, as the case may be, taken together, shall constitute but one and the
same instrument.

       

      Section
9.7                                Binding
Effect; Assignment and Participations.

       

      (a)           Generally. The Loan Documents
shall be binding upon and inure to the benefit of the Borrower and the Lenders
and their respective successors and assigns, except that (i) the Borrower
shall not have the right to assign its rights thereunder or any interest therein
without the prior written consent of each of the Lenders, and (ii) except
as set forth in this Section 9.7, no Lender may assign or grant any
participation in any of its rights or obligations under any Loan
Document.

       

      (b)           Participations. Any Lender
may, at any time, grant participations in a portion of its Note and Commitment
to any institutional investor on any date selected by such Lender. Any Lender
proposing a participation hereunder shall give notice of such participation to
the Agent at least ten Business Days prior to such participation (unless the
Agent consents to a shorter period of time). Such notice shall specify the
identity of the proposed purchaser of the participation and the amount of the
proposed participation. No such partial participation shall be permitted if the
principal amount thereof would be less than $5,000,000. No holder of any such
participation,

      
        
           

        

        
          34

          
            

          

        

        
           

        

      

      other
than an affiliate of such Lender, shall be entitled to require such Lender to
take or omit to take any action hereunder, except that such Lender may agree
with such participant that such Lender will not, without such participant’s
consent, (i) forgive any indebtedness of the Borrower under this Agreement
or the Notes, (ii) agree to reduce the rate of interest charged under this
Agreement, or (iii) agree to extend the final maturity of any indebtedness
evidenced by the Notes, except as expressly provided by the terms of the Loan
Documents. No Lender shall, as between the Borrower and such Lender, be relieved
of any of its obligations hereunder as a result of any such granting of a
participation. The Borrower hereby acknowledges and agrees that any participant
described in this Section will, for purposes of Section 2.9, be considered to be
a Lender hereunder (provided that such participant shall not be entitled to
receive any more than the Lender selling such participation would have received
had such sale not taken place) and may rely on, and possess all rights under,
any opinions, certificates, or other instruments or documents delivered under or
in connection with any Loan Document (it being understood that each opinion
delivered hereunder speaks only as of the date thereof).

       

      (c)           Assignments. Any Lender may,
at any time, assign a portion of its Note and Commitment to an Eligible Lender
(an “Applicant”) on any date (the “Adjustment Date”) selected by such Lender.
Any Lender proposing an assignment hereunder shall give notice of such
assignment to the Agent at least ten Business Days prior to such assignment
(unless the Agent consents to a shorter period of time). Such notice shall
specify the identity of such Applicant and the Percentage which it proposes that
such Applicant acquire (which Percentage shall be the same for the Commitment
and the Note held by the assigning Lender). No such partial assignment shall be
permitted if, immediately after giving effect to such assignment, either the
Credit Exposure of the Applicant or the Credit Exposure of the assigning Lender
would be less than $5,000,000. The notice of assignment shall contain a
representation by the Applicant to the effect that none of the consideration
used to make the purchase of the Note and Commitment under the applicable
assignment agreement constitutes “plan assets” as defined under ERISA and that
the rights and interests of the Applicant in and under the Loan Documents will
not be “plan assets” under ERISA. Any Lender making an assignment under this
Section shall pay the Agent a transfer fee in the amount of $3,500
simultaneously with such assignment.

       

      (d)           Consents. Any assignment
hereunder may be made, and any participation granted, only with the prior
written consent of the Agent and the Borrower; provided, however, that
(i) in no event shall such consent be unreasonably withheld or delayed,
(ii) the consent of the Borrower shall not be required if any Default or
Event of Default has occurred and is continuing at the time of such assignment
or grant of participation, (iii) no such consent of the Borrower and the
Agent shall be required for the assignment by any Lender of, or grant of a
participation in, all or any part of its Commitment and Note to one or more
other Persons that are Lenders immediately prior to such assignment, and
(iv) no such consent of the Borrower and the Agent shall be required for
the assignment by any Lender of, or grant of a participation in, all or any part
of its Commitment and Note to one or more affiliates of such Lender, provided
that, unless consented to by the Borrower and the Agent (which consent shall not
be unreasonably withheld), no such assignment under this clause (iv) shall
relieve the transferring Lender from its obligations hereunder.

       

      (e)           Assignment Certificate and
Notes. To confirm the status of each Additional Lender as a party to this
Agreement and to evidence the assignment in accordance herewith:

       

      
        	
                 
      

              	
                 (i)

              	
                the
      Borrower, such Lender, such Applicant, and the Agent shall, on or before
      the Adjustment Date, execute and deliver to the Agent an Assignment
      Certificate in substantially the form of Exhibit D (an “Assignment
      Certificate”) (provided that the assignment will be effective without the
      signature of the Borrower or
the

              

      

      
        
           

        

        
          35

          
            

          

        

        
           

        

      

      Agent to
the extent that the consent of the Borrower or the Agent, as the case may be, is
not required hereunder); and

       

      
        	
                 
      

              	
                (ii)

              	
                the
      Borrower will, at its own expense, execute and deliver to the Additional
      Lender a new Note, payable to the order of the Additional Lender in an
      amount corresponding to the applicable interest in the assigning Lender’s
      rights and obligations acquired by such Applicant pursuant to such
      assignment, and, if the assigning Lender has retained interests in such
      rights and obligations, a new Note, payable to the order of that Lender in
      an amount corresponding to such retained interests. Such new Notes shall
      be in an aggregate principal amount equal to the aggregate principal
      amount of the applicable Note to be replaced by such new Notes, shall be
      dated the effective date of such assignment and shall otherwise be in the
      form of the Note to be replaced thereby. Such new Notes shall be issued in
      substitution for, but not in satisfaction or payment of, the Notes being
      replaced thereby.

              

      

       

      
        	
                 
      

              	
                Upon
      the execution and delivery of such Assignment Certificate and such Notes,
      (a) this Agreement shall be deemed to be amended to the extent, and
      only to the extent, necessary to reflect the addition of such Additional
      Lender and the resulting adjustment of Percentages arising therefrom, (b)
      the assigning Lender shall be relieved of all obligations hereunder to the
      extent of the reduction of all obligations hereunder and to the extent of
      the reduction of such Lender’s Percentage, and (c) the Additional Lender
      shall become a party hereto and shall be entitled to all rights, benefits
      and privileges accorded to a Lender herein and in each other document or
      instrument executed pursuant hereto and subject to all obligations of a
      Lender hereunder, including the right to approve or disapprove actions
      which, in accordance with the terms hereof, require the approval of the
      Required Lenders or all Lenders, and, if the Term Loan has not yet been
      made, the obligation to advance its Percentage of the Term Loan
      hereunder.

              

      

       

      (f)           Federal Reserve Bank Security
Interests. Notwithstanding the foregoing, each Lender may at any time
grant a security interest in all or any portion of its rights under this
Agreement and that Lender’s Note in favor of any Federal Reserve Bank in
accordance with Regulation A of the Board of Governors of the Federal Reserve
System.

       

      (g)           Borrower Cooperation. In
order to facilitate the addition of Additional Lenders hereto, the Borrower
shall cooperate fully with each Lender and the Agent in connection therewith and
shall provide all reasonable assistance requested by each Lender and the Agent
relating thereto, including, without limitation, the furnishing of such written
materials and financial information regarding the Borrower as any Lender or the
Agent may reasonably request, the execution of such documents as any Lender or
the Agent may reasonably request with respect thereto, and the participation by
officers of the Borrower in a meeting or teleconference call with any Applicant
upon the reasonable request of any Lender or the Agent.

of Information.

       

      The Agent
and the Lenders shall keep confidential (and cause their respective officers,
directors, employees, agents and representatives to keep confidential) all
information, materials and documents furnished by the Borrower, the Agent or the
Lenders (the “Disclosed Information”). Notwithstanding the foregoing, the Agent
and each Lender may disclose Disclosed Information (i) to the Agent, any
other Lender or any Affiliate of any Lender; (ii) to legal counsel,
accountants and other professional advisors to the Agent or such Lender;
(iii) to any regulatory body having jurisdiction over any Lender or the

publicly available other than as a result of a breach of this Agreement, (B)
becomes available to the Agent or such Lender on a non-confidential basis from a
source other than the Borrower or a Subsidiary, or (C) was available to the
Agent or such Lender on a non-confidential basis prior to its disclosure to the
Agent or such Lender by the Borrower or a Subsidiary; (vi) to the extent
the Borrower or such Subsidiary shall have consented to such disclosure in
writing; (vii) to the extent reasonably deemed necessary by the Agent or
any Lender in the enforcement of the remedies of the Agent and the Lenders
provided under the Loan Documents; or (viii) in connection with any
potential assignment or participation in the interest granted hereunder,
provided that any such potential assignee or participant shall have executed a
confidentiality agreement imposing on such potential assignee or participant
substantially the same obligations as are imposed on the Agent and the Lenders
under this Section 9.8.

suit, action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law
after all appeals have been exhausted.

enter into any trust indenture, credit agreement or other agreement for,
relating to, or amending any terms or conditions applicable to any unsecured
indebtedness in an amount not less than $15,000,000, the Borrower shall promptly
so advise the Agent. Thereupon, if the Required Lenders shall determine that
such trust indenture, credit agreement or other agreement includes covenants or
defaults reasonably determined by

into an amendment to this Agreement providing for substantially the same such
covenants and defaults as those provided for in such trust indenture, credit
agreement or other agreement, to the extent required and as may be selected by
the Required Lenders, such amendment to remain in effect for the entire duration
of the term to maturity of such indebtedness (to and including the date to which
the same may be extended); provided, however, that if any such trust indenture,
credit agreement or other agreement shall be modified, supplemented, amended or
terminated so as to modify, amend or eliminate such trust indenture or other
agreement or any such covenant, term, condition or default so made a part of
this Agreement, then, the Borrower shall give the Agent and the Lenders prompt
notice thereof and such modification, supplement or amendment shall operate to
modify, amend or eliminate such covenants, term, condition or default as so made
a part of this Agreement. Notwithstanding the foregoing, in no event shall this
Section 9.14 be construed so as to require the Borrower at any time to grant any
Lien in favor of the Agent or the Lenders hereunder.

      Reference

      This is a
Compliance Certificate submitted in connection with the Borrower’s financial
statements (the “Statements”) as of _____________________, _______ (the

      I hereby
certify to you as follows:

       

      
        	
                 
      

              	
                1.

              	
                I
      am the chief financial officer of the Borrower, and I am familiar with the
      financial statements and financial affairs of the
  Borrower.

              

      

       

      
        	
                 
      

              	
                2.

              	
                The
      Statements have been prepared in accordance with GAAP, except for any
      portion thereof provided pursuant to Section 5.1(a)(iii), which have been
      prepared in accordance with FERC Accounting
  Principles.

              

      

       

      
        	
                 
      

              	
                3.

              	
                The
      computations attached hereto have been prepared in accordance with GAAP
      and set forth the Borrower’s compliance or non-compliance with the
      requirements set forth in the Financial Covenants as of the Effective
      Date. Such computations below have been prepared from, and on a basis
      consistent with, the Statements. Further attached hereto are all relevant
      facts in reasonable detail to evidence, and the computations of, the
      financial covenants referred to
above.

              

      

       

      
        	
                 
      

              	
                4.

      Exhibit
E-1

       

      September
26, 2008

       

      Wells
Fargo Bank, National Association, as Agent and as the sole initial
Lender

       

      Ladies
and Gentlemen:

       

      I am the
General Counsel of MDU Resources Group, Inc., a Delaware corporation (the
“Company”), and in such capacity, I am familiar with (a) the negotiation,
preparation, execution and delivery of that certain Term Loan Agreement, dated
as of September 26, 2008 (the “Agreement”), by and among the Company, the
several financial institutions from time to time party thereto, and Wells Fargo
Bank, National Association, as Agent, and (b) the negotiation, preparation,
execution and delivery of the other Loan Documents listed on Schedule A hereto
(together with the Agreement, the “Loan Documents”). This opinion is furnished
to you pursuant to Section 3.1(d) of the Agreement and at the instruction of the
Company. All capitalized terms used but not otherwise defined herein have the
meanings ascribed thereto in the Agreement.

       

      For the
purpose of rendering the opinions contained herein, I have examined and reviewed
the Agreement and the other Loan Documents. I have also examined the originals,
or copies certified to my satisfaction, of the Restated Certificate of
Incorporation and By-Laws of the Company, resolutions adopted by the Board of
Directors of the Company authorizing the execution, delivery and performance by
the Company of the Agreement and the other Loan Documents, and such other
corporate records of the Company and agreements, instruments and other documents
as I have deemed necessary as a basis for the opinions expressed below. In my
examination, I have assumed the genuineness of all signatures, other than the
signatures of the Company on the Loan Documents to which it is a party, the
legal capacity of natural persons, the authenticity of all documents submitted
to me as originals and the conformity with original documents of all documents
submitted to me as certified or photostatic copies. I have also assumed, with
your consent, the due execution and delivery, pursuant to due authorization, of
the Agreement by all parties thereto other than the Company and the validity and
binding effect of the Agreement upon such parties.

       

      As to any
facts that I did not independently establish or verify, I have relied without
independent investigation upon statements, representations and certificates of
officers of the Company and as to the matters addressed therein, upon
certificates or communications from public officials. As used herein, the phrase
“to my knowledge” with respect to the existence or absence of facts is intended
to signify that, while I have made no specific inquiry or other independent
examination to determine the existence or absence of such facts, no factual
information has come to my attention which causes me to believe that such facts
are not accurate.

       

      Based on
and subject to the foregoing and upon such investigation as I have deemed
necessary, and subject to the qualifications set forth below, it is my opinion
that:

       

      1.           The
Company is a corporation duly incorporated, validly existing and in good
standing under the laws of Delaware.

       

      2.           The
Company is duly qualified as a foreign corporation to transact business and is
in good standing in Iowa, Minnesota, Montana, Nebraska, North Dakota, South
Dakota and Wyoming, and is not required, whether by reason of ownership or
leasing of property or the conduct of its business,

      
        
           

        

        
          49

          
            

          

        

        
           

        

      

      to be
qualified in any other jurisdiction, except where the failure so to qualify or
to be in good standing would not result in a Material Adverse
Effect.

       

      3.           The
Company has the corporate power and authority to execute, deliver and perform
its obligations under the Agreement and the other Loan Documents applicable to
it, and has all requisite corporate power and authority, licenses and permits to
own its assets and to carry on its business as currently conducted and as
contemplated to be conducted by the Agreement.

       

      4.           The
execution, delivery and performance by the Company of the Agreement and each of
the other Loan Documents to which it is a party have been duly authorized by all
necessary corporate action and by all necessary public utility commissions and
other regulatory bodies having jurisdiction over the Company, and each of the
Agreement and the other Loan Documents has been duly executed and delivered by
the Company.

       

      5.           The
execution, delivery and performance by the Company of the Agreement and of the
other Loan Documents to which it is a party, and the borrowing thereunder, do
not and will not (a) require any consent or approval of the stockholders of the
Company or any authorization, consent or approval by any governmental
department, commission, board, bureau, agency or instrumentality, other than
Authorizing Orders set forth in Schedule 4.2 to the Agreement, each of
which Authorizing Orders has been obtained and is in full force and effect, (b)
violate any provision of any law, rule or regulation or any order, writ,
injunction or decree presently in effect having applicability to the Company or
the Restated Certificate of Incorporation or By-Laws of the Company, (c) result
in a breach of or constitute a default under any indenture or loan or credit
agreement or any other agreement, lease or instrument to which the Company is a
party or by which its properties may be bound or affected, or (d) except as
provided therein, result in, or require, the creation or imposition of any Lien
or other charge or encumbrance of any nature  upon or with respect to
any of its properties.

       

      6.           Except
as set forth in the Company’s Annual Report on Form 10-K for the year ended
December 31, 2007, or in any document subsequently filed by the Company pursuant
to Section 13, 14 or 15(d) of the Exchange Act, there are no actions, suits or
proceedings pending or, to my knowledge, threatened against or affecting the
Company or the properties of the Company before any court or governmental
department, commission, board, bureau, agency or instrumentality, which, if
determined adversely to the Company, would have a Material Adverse
Effect.

       

      7.           The
Term Loan has been duly authorized by the Borrower’s Board of Directors pursuant
to resolutions adopted thereby on July 10, 2008, which authority remains in full
force and effect on the date hereof.

       

      8.           Without
limiting the generality of the foregoing, the Term Loan complies with all
applicable requirements of each applicable resolution of the Borrower’s Board of
Directors and each applicable Authorizing Order, including but not limited to
any applicable limitation on the aggregate amount of short-term or long-term
debt that the Borrower may have outstanding at any one time.

       

      The
opinions expressed herein are limited to the laws of the State of North Dakota
and the General Corporation Law of the State of Delaware. I am a member of the
Minnesota and North Dakota Bars and do not hold myself out as an expert on the
laws of the States of Iowa, Montana, Nebraska, South Dakota or Wyoming, but have
made a study through counsel located in such jurisdictions or otherwise of the
laws of such jurisdictions insofar as such laws are involved in the conclusions
expressed in this opinion. Insofar as the opinions expressed herein relate to
the General Corporation Law of the State of Delaware, or the federal laws of the
United States of America, I have relied with your consent on the opinion, of
even date herewith, of Thelen LLP.

      
        
           

        

        
          50

          
            

          

        

        
           

        

      

       

      This
opinion is intended solely for your use and is rendered solely in connection
with the Agreement and the other Loan Documents, and without my written consent
may not be (a) relied upon by you for any other purpose, or (b) relied upon by
any other person or entity for any purpose, except that Thelen LLP, special
counsel to the Company, may rely on the opinions expressed herein in rendering
to you their opinion of even date herewith. The opinions expressed above are
limited to the law and facts in effect on the date hereof. I disclaim any
obligation to advise you of facts, circumstances, events or developments which
hereafter may be brought to my attention and which might alter, affect or modify
the opinions expressed herein.

       

      I hereby
consent to reliance by the Agent and the Lenders now or hereafter parties to the

      September

      Wells
Fargo Bank, National Association, as Agent and as the sole initial
Lender

       

      Ladies
and Gentlemen:

       

      We have
acted as special counsel for MDU Resources Group, Inc., a Delaware corporation
(the “Company”), in connection with (a) the negotiation, preparation, execution
and delivery of that certain Term Loan Agreement, dated as of September 26, 2008
(the “Agreement”), by and among the Company, the several financial institutions
from time to time party thereto, and Wells Fargo Bank, National Association, as
Agent, and (b) the negotiation, preparation, execution and delivery of the other
Loan Documents listed on Schedule A hereto (together with the Agreement, the
“Loan Documents”). This opinion is furnished to you pursuant to Section 3.1(d)
of the Agreement and at the instruction of the Company. All capitalized terms
used but not otherwise defined herein have the meanings ascribed thereto in the
Agreement.

       

      For the
purpose of rendering the opinions contained herein, we have examined and
reviewed the Agreement and the other Loan Documents. We have also examined the
originals, or copies certified to our satisfaction, of the Restated Certificate
of Incorporation and By-Laws of the Company, resolutions adopted by the Board of
Directors of the Company authorizing the execution, delivery and performance by
the Company of the Agreement and the other Loan Documents, and such other
corporate records of the Company and agreements, instruments and other documents
as we have deemed necessary as a basis for the opinions expressed below. In our
examination, we have assumed the genuineness of all signatures, the legal
capacity of natural persons, the authenticity of all documents submitted to us
as originals and the conformity with original documents of all documents
submitted to us as certified or photostatic copies. We have also assumed, with
your consent, the due execution and delivery, pursuant to due authorization, of
the Agreement by all parties thereto other than the Company and the validity and
binding effect of the Agreement upon such parties. As to any facts that we did
not independently establish or verify, we have relied without independent
investigation upon statements, representations and certificates of officers of
the Company and as to the matters addressed therein, upon certificates or
communications from public officials.

       

      Based on
and subject to the foregoing and upon such investigation as we have deemed
necessary, and subject to the qualifications set forth below, it is our opinion
that:

       

      1.           The
Company is a corporation duly incorporated, validly existing and in good
standing under the laws of Delaware.

       

      2.           The
Company has the corporate power and authority to execute, deliver and perform
its obligations under the Agreement and the other Loan Documents applicable to
it.

       

      3.           The
execution, delivery and performance by the Company of the Agreement and each of
the other Loan Documents to which it is a party have been duly authorized by all
necessary corporate action, and each of the Agreement and the other Loan
Documents has been duly executed and delivered by the Company.

       

      4.           The
execution, delivery and performance by the Company of the Agreement and of the
other Loan Documents to which it is a party do not and will not (a) require any
consent or approval

      
        
           

        

        
          53

          
            

          

        

        
           

        

      

      of the
stockholders of the Company or any authorization, consent or approval by any
governmental department, commission, board, bureau, agency or instrumentality,
other than Authorizing Orders set forth in Schedule 4.2 to the Agreement,
each of which Authorizing Orders has been obtained and is in full force and
effect, or (b) violate any provision of any law, rule or regulation or any
order, writ, injunction or decree presently in effect having applicability to
the Company or the Restated Certificate of Incorporation or By-Laws of the
Company.

       

      5.           Each
of the Agreement and each of the Loan Documents to which the Company is a party
constitutes a legal, valid and binding obligation of the Company enforceable in
accordance with its respective terms, subject to the effect of any applicable
bankruptcy, insolvency, moratorium or other similar laws affecting creditors’
rights generally and of general principles of equity (regardless of whether
applied in a proceeding in equity or at law), except that we express no opinion
as to (a) Section 2.8(c) and Section 7.2(c) of the Agreement, (b) the
enforceability of rights to indemnity under federal or state securities laws, or
(c) the enforceability of waivers of the parties of their respective rights and
remedies under law.

       

      This
opinion is limited to the laws of the State of New York, the General Corporation
Law of the State of Delaware, and the federal laws of the United States of
America. We express no opinion as to the laws of any other
jurisdiction.

       

      In
rendering this opinion, we have relied as to all matters of Iowa, Minnesota,
Montana, Nebraska, North Dakota, South Dakota and Wyoming law, as to matters
addressed therein, with your consent, upon the opinion of Paul K. Sandness,
Bismarck, North Dakota, the General Counsel of the Company.

       

      This
opinion is intended solely for your use and is rendered solely in connection
with the Agreement and the other Loan Documents, and without our written consent
may not be (a) relied upon by you for any other purpose, or (b) relied upon by
any other person or entity for any purpose, except that Paul K. Sandness may
rely on the opinions expressed herein in rendering to you his opinion of even
date herewith.

       

      The
opinions expressed above are limited to the law and facts in effect on the date
hereof. We disclaim any obligation to advise you of facts, circumstances, events
or developments which hereafter may be brought to our attention and which might
alter, affect or modify the opinions expressed herein.

       

      We hereby
consent to reliance by the Agent and the Lenders now or hereafter parties to the
Agreement on the opinions expressed herein.

       

                                                                          Very truly
