                  any error
                  therein, shall not in any manner affect the obligation of Borrowers
                  to
                  repay the Revolving Credit Advances (and all other amounts owing
                  with
                  respect thereto) made to Borrowers by the Revolving Credit Lenders
                  in
                  accordance with the terms of this
                  Agreement.

                Each
                  Borrower agrees that, upon written request to the Agent by any
                  Revolving
                  Credit Lender, such Borrower will execute and deliver, to such
                  Revolving
                  Credit Lender, at such Borrower’s own expense, a Revolving Credit Note
                  evidencing the outstanding Revolving Credit Advances owing to such

                  or
                  conversion of an outstanding Revolving Credit Advance), which must
                  be a
                  Business Day;

              

      

      

      
        	
                 

              	
                (ii)

              	
                whether
                  such Advance is a new Revolving Credit Advance or a refunding or
                  conversion of an outstanding Revolving Credit Advance;
                  and

              

      

      

      
        	
                 

              	
                (iii)

              	
                whether

                  under
                  this Agreement shall be a Prime-based Advance, which may then be
                  converted
                  into a Eurodollar-based Advance in compliance with this
                  Agreement.

      Agent,
        acting on behalf of the Revolving Credit Lenders, may also, at its option,
        lend
        under this Section 2.3 upon the telephone or email request of an Authorized
        Signer of the Borrower Representative to make such requests and, in the event
        Agent, acting on behalf of the Revolving Credit Lenders, makes any such Advance
        upon a telephone or email request, an Authorized Signer shall fax or deliver
        by
        electronic file to Agent, on the same day as such telephone or email request,
        an
        executed Request for Revolving Credit Advance. Each Borrower hereby authorizes
        Agent to disburse Advances under this Section 2.3 pursuant to the telephone
        or
        email instructions of any person purporting to be an Authorized Signer.
        Notwithstanding the foregoing, Borrowers acknowledge that Borrowers shall
        bear
        all risk of loss resulting from disbursements made upon any telephone or
        email
        request. Each telephone or email request for an Advance from an Authorized
        Signer for the Borrower Representative shall constitute a certification by
        the
        Borrowers of the matters set forth in the Request for Revolving Credit Advance
        form as of the date of such requested Advance.

      

      2.4           Disbursement
        of Advances.

      

      (a)           Upon
        receiving any Request for Revolving Credit Advance from Borrowers under Section
        2.3 hereof, Agent shall promptly notify each Revolving Credit Lender by wire,
        telex or telephone (confirmed by wire, telecopy or telex) of the amount of
        such
        Advance being requested and the date such Revolving Credit Advance is to
        be made
        by each Revolving Credit Lender in an amount equal to its Revolving Credit
        Percentage of such Advance. Unless such Revolving Credit Lender’s commitment to
        make Revolving Credit Advances hereunder shall have been suspended or terminated
        in accordance with this Agreement, each such Revolving Credit Lender shall
        make
        available the amount of its Revolving Credit Percentage of each Revolving
        Credit
        Advance in immediately available funds to Agent, as follows:

      

      
        	
                 

              	
                (i)

              	
                for
                  Prime-based Advances, at the office of Agent located at One Detroit
                  Center, Detroit, Michigan 48226, not later than 1:00 p.m. (Detroit

                (ii)

              	
                for
                  Eurodollar-based Advances, at the Agent’s Correspondent for the account of
                  the Eurodollar Lending Office of the Agent, not later than 12:00
                  p.m. (the
                  time of the Agent’s Correspondent) on the date of such
                  Advance.

              

      

      

      (b)           Subject
        to submission of an executed Request for Revolving Credit Advance by Borrowers
        without exceptions noted in the compliance certification therein, Agent shall
        make available to Borrowers the aggregate of the amounts so received by it
        from
        the Revolving Credit Lenders in Dollars:

      

      
        	
                 

              	
                (i)

              	
                for
                  Prime-based Advances, not later than 4:00 p.m. (Detroit time) on
                  the date
                  of such Revolving Credit Advance, by credit to an account of Borrowers
                  maintained with Agent or to such other account or third party as
                  Borrowers
                  may reasonably direct in writing, provided such direction is timely
                  given;
                  and

              

      

      
        
          
          

        

        
          26

          
            

          

        

        
          
          

        

      

      
        	
                 

              	
                (ii)

              	
                for
                  Eurodollar-based Advances, not later than 4:00 p.m. (the time of
                  the
                  Agent’s Correspondent) on the date of such Revolving Credit Advance,
                  by
                  credit to an account of Borrowers maintained with Agent’s Correspondent or
                  to such other account or third party as Borrowers may direct, provided
                  such direction is timely given.

              

      

      

      (c)           Agent
        shall deliver the documents and papers received by it for the account of
        each
        Revolving Credit Lender to such Revolving Credit Lender. Unless Agent shall
        have
        been notified by any Revolving Credit Lender prior to the date of any proposed
        Revolving Credit Advance that such Revolving Credit Lender does not intend
        to
        make available to Agent such Revolving Credit Lender’s Percentage of such
        Advance, Agent may assume that such Revolving Credit Lender has made such
        amount
        available to Agent on such date, as aforesaid.  Agent may, but shall
        not be obligated to, make available to Borrowers the amount of such payment
        in
        reliance on such assumption. If such amount is not in fact made available
        to
        Agent by such Revolving Credit Lender, as aforesaid, Agent shall be entitled
        to
        recover such amount on demand from such Revolving Credit Lender. If such
        Revolving Credit Lender does not pay such amount forthwith upon Agent’s demand
        therefor and the Agent has in fact made a corresponding amount available
        to
        Borrowers, the Agent shall promptly notify Borrowers and Borrowers shall
        pay
        such amount to Agent, if such notice is delivered to Borrowers prior to 1:00
        p.m. (Detroit time) on a Business Day, on the day such notice is received,
        and
        otherwise on the next Business Day, and such amount paid by Borrowers shall
        be
        applied as a prepayment of the Revolving Credit (without any corresponding
        reduction in the Revolving Credit Aggregate Commitment), reimbursing Agent
        for
        having funded said amounts on behalf of such Revolving Credit
        Lender.  The Borrowers shall retain their claims against such
        Revolving Credit Lender with respect to the amounts repaid by it to Agent
        and,
        if such Revolving Credit Lender subsequently makes such amounts available
        to
        Agent, Agent shall promptly make such amounts available to the Borrowers
        as a
        Revolving Credit Advance. Agent shall also be entitled to recover from such
        Revolving Credit Lender or Borrowers, as the case may be, but without
        duplication, interest on such amount in respect of each day from the date
        such
        amount was made available by Agent to Borrowers, to the date such amount
        is
        recovered by Agent, at a rate per annum equal to:

      

      
        	
                 

              	
                (i)

              	
                in
                  the case of such Revolving Credit Lender, for the first two (2)
                  Business
                  Days such amount remains unpaid, the Federal Funds Effective Rate,
                  and
                  thereafter, at the rate of interest then applicable to such Revolving
                  Credit Advances; and

                in
                  the case of Borrowers, the rate of interest then applicable to
                  such
                  Advance of the Revolving Credit.

              

      

      

      Until
        such Revolving Credit Lender has paid Agent such amount, such Revolving Credit
        Lender shall have no interest in or rights with respect to such Advance for
        any
        purpose whatsoever.  The obligation of any Revolving Credit Lender to
        make any Revolving Credit Advance hereunder shall not be affected by the
        failure
        of any other Revolving Credit Lender to make any Advance hereunder, and no
        Revolving Credit Lender shall have any liability to the Borrowers or any
        of
        their respective Subsidiaries, the Agent, any other Revolving Credit Lender,
        or
        any other party for another Revolving Credit Lender’s failure to make any loan
        or Advance hereunder.

           Swing Line Advances  (a) Commitment.
        The Swing Line Lender may, on the terms and subject to the conditions
        hereinafter set forth (including without limitation Section 2.5(c) hereof),
        but
        shall not be required to, make one or more Advances (each such advance being
        a
“Swing Line Advance”) to the Borrowers from time to time on any Business Day
        during the period from the Effective Date hereof until (but excluding) the
        Revolving Credit Maturity Date in an aggregate amount not to exceed at any
        one
        time outstanding the Swing Line Maximum Amount. Subject to the terms set
        forth
        herein, advances, repayments and readvances may be made under the Swing
        Line.

                Swing
                  Line Lender shall maintain in accordance with its usual practice
                  an
                  account or accounts evidencing indebtedness of the Borrowers to
                  Swing Line
                  Lender resulting from each Swing Line Advance from time to time,
                  including
                  the amount and date of each Swing Line Advance, its Applicable
                  Interest
                  Rate, its Interest Period, if any, and the amount and date of any
                  repayment made on any Swing Line Advance from time to time. The
                  entries
                  made in such account or accounts of Swing Line Lender shall be
                  prima facie
                  evidence, absent manifest error, of the existence and amounts of
                  the
                  obligations of the Borrowers therein recorded; provided, however,
                  that the
                  failure of Swing Line Lender to maintain such account, as applicable,
                  or
                  any error therein, shall not in any manner affect the obligation
                  of the
                  Borrowers to repay the Swing Line Advances (and all other amounts
                  owing
                  with respect thereto) in accordance with the terms of this
                  Agreement.

                Each
                  Borrower unconditionally promises to pay, jointly and severally,
                  to the
                  Swing Line Lender the then unpaid principal amount of such Swing
                  Line

                  as may be
                  required from time to time pursuant to this Agreement.  Subject

                  from
                  time to time after the date of such Advance (until paid), bear
                  interest at
                  its Applicable Interest Rate.

                  time and
                  from time to time and so long as the Agent is the Swing Line Lender,
                  Borrowers may utilize the Agent’s “Sweep to Loan” automated system for

“Sweep
                  to Loan” system, Borrowers shall be deemed to have certified to the Agent
                  and the Lenders each of the matters set forth in clause (vi) of
                  this
                  Section 2.5(b).  Principal and interest on Swing Line Advances

                  pursuant to the terms and conditions of the Sweep Agreement without
                  any
                  deduction, setoff or counterclaim whatsoever.  Unless sooner
                  paid pursuant to the provisions hereof or the provisions of the
                  Sweep
                  Agreement, the principal amount of the Swing Loans shall be paid
                  in full,
                  together with accrued interest thereon, on the Revolving Credit

                  the “Sweep to Loan” system at any time and from time to time for any
                  reason and, immediately upon any such revocation, the “Sweep to Loan”
                  system shall no longer be available to Borrowers for the funding
                  of Swing
                  Line Advances hereunder (or otherwise), and the regular procedures
                  set
                  forth in this Section 2.5 for the making of Swing Line Advances
                  shall be
                  deemed immediately to apply. Agent may, at its option, also elect
                  to make
                  Swing Line Advances upon the Borrower Representative’s telephone requests
                  on the basis set forth in the last paragraph of Section 2.3, provided
                  that
                  the Borrowers comply with the provisions set forth in this Section
                  2.5.

                  of the
                  conditions set forth in Section 2.5(c) hereof, Swing Line Lender
                  shall
                  make available to Borrowers the amount so requested in Dollars
                  not later
                  than 4:00 p.m. (Detroit time) on the date of such Advance, by credit

                  or
                  third party as the Borrowers may reasonably direct in writing,
                  subject to
                  applicable law, provided such direction is timely given. Swing
                  Line Lender
                  shall promptly notify Agent of any Swing Line Advance by telephone,
                  telex

                The
                  Agent, at any time in its sole and absolute discretion, may, in
                  each case
                  on behalf of the Borrowers (which hereby irrevocably directs the
                  Agent to
                  act on their behalf) request each of the Revolving Credit Lenders
                  (including the Swing Line Lender in its capacity as a Revolving
                  Credit
                  Lender) to make an Advance of the Revolving Credit to Borrowers,
                  in an
                  amount equal to such Revolving Credit Lender’s Revolving Credit Percentage
                  of the aggregate principal amount of the Swing Line Advances outstanding
                  on the date such notice is given (the “Refunded Swing Line Advances”);
                  provided however that the Swing Line Advances carried at the Quoted
                  Rate
                  which are refunded with Revolving Credit Advances at the request
                  of the
                  Swing Line Lender at a time when no Default or Event of Default
                  has
                  occurred and is continuing shall not be subject to Section 11.1
                  and no
                  losses, costs or expenses may be assessed by the Swing Line Lender
                  against
                  the Borrowers or the Revolving Credit Lenders as a consequence
                  of such
                  refunding. The applicable Revolving Credit Advances used to refund
                  any
                  Swing Line Advances shall be Prime-based Advances. In connection
                  with the
                  making of any such Refunded Swing Line Advances or the purchase
                  of a
                  participation interest in Swing Line Advances under Section 2.5(e)(ii)
                  hereof, the Swing Line Lender shall retain its claim against Borrowers
                  for
                  any unpaid interest or fees in respect thereof accrued to the date
                  of such
                  refunding. Unless any of the events described in Section 9.1(i)
                  hereof
                  shall have occurred (in which event the procedures of Section 2.5(e)(ii)
                  shall apply) and regardless of whether the conditions precedent
                  set forth
                  in this Agreement to the making of a Revolving Credit Advance are
                  then
                  satisfied (but subject to Section 2.5(e)(iii)), each Revolving
                  Credit
                  Lender shall make the proceeds of its Revolving Credit Advance
                  available
                  to the Agent for the benefit of the Swing Line Lender at the office
                  of the
                  Agent specified in Section 2.4(a) hereof prior to 11:00 a.m. Detroit
                  time
                  on the Business Day next succeeding the date such notice is given,
                  in
                  immediately available funds. The proceeds of such Revolving Credit
                  Advances shall be immediately applied to repay the Refunded Swing
                  Line
                  Advances, subject to Section 11.1
                  hereof.

                  prior to the making of an Advance of the Revolving Credit pursuant
                  to
                  Section 2.5(e)(i) hereof, one of the events described in Section
                  9.1(i)
                  hereof shall have occurred, each Revolving Credit Lender will,
                  on the date
                  such Advance of the Revolving Credit was to have been made, purchase
                  from
                  the Swing Line Lender an undivided participating interest in each
                  Swing
                  Line Advance that was to have been refunded in an amount equal
                  to its
                  Revolving Credit Percentage of such Swing Line Advance. Each Revolving
                  Credit Lender within the time periods specified in Section 2.5(e)(i)
                  hereof, as applicable, shall immediately transfer to the Agent,
                  for the
                  benefit of the Swing Line Lender, in immediately available funds,
                  an
                  amount equal to its Revolving Credit Percentage of the aggregate
                  principal
                  amount of all Swing Line Advances outstanding as of such
                  date.  Upon receipt thereof, the Agent will deliver to such
                  Revolving Credit Lender a Swing Line Participation Certificate
                  evidencing
                  such participation.

                  including, without limitation, (A) any set-off, counterclaim, recoupment,
                  defense or other right which such Revolving Credit Lender may have
                  against
                  Swing Line Lender, Borrowers or any other Person for any reason
                  whatsoever; (B) the occurrence or continuance of any Default or

                  Default; (C) any adverse change in the condition (financial or
                  otherwise)
                  of Borrowers or any other Person; (D) any breach of this Agreement
                  or any
                  other Loan Document by Borrowers or any other Person; (E) any inability
                  of
                  Borrowers to satisfy the conditions precedent to borrowing set
                  forth in

                  or not

                  make available to the Agent the amount required pursuant to Section
                  2.5(e)(i) or (ii) hereof, as the case may be, the Agent on behalf
                  of the
                  Swing Line Lender, shall be entitled to recover such amount on
                  demand from
                  such Revolving Credit Lender, together with interest thereon for
                  each day
                  from the date of non-payment until such amount is paid in full
                  (x) for the

                  required pursuant to Section 2.5(e)(i) or (ii) hereof shall not
                  be
                  affected by the failure of any other Revolving Credit Lender to
                  make such
                  amounts available, and no Revolving Credit Lender shall have any
                  liability

                  matters
                  concerning this Agreement shall have received written notice from
                  Agent or
                  any Lender that Swing Line Advances should be suspended based on
                  the
                  occurrence and continuance of a Default or Event of Default and
                  stating
                  that such notice is a “notice of default”; provided, however that the
                  obligation of  the Revolving Credit Lenders to make such
                  Revolving Credit Advances (or purchase such participations) shall
                  be
                  reinstated upon the date on which such Default or Event of Default
                  has
                  been waived by the requisite
                  Lenders.

      (a)           Interest
        on the unpaid balance of all Prime-based Advances of the Revolving Credit
        and
        the Swing Line from time to time outstanding shall accrue from the date of
        such
        Advance to the date repaid, at a per annum interest rate equal to the
        Prime-based Rate, and shall be payable in immediately available funds commencing
        on December 1, and on the first day of each calendar month thereafter. Whenever
        any payment under this Section 2.6(a) shall become due on a day which is
        not a
        Business Day, the date for payment thereof shall be extended to the next
        Business Day. Interest accruing at the Prime-based Rate shall be computed
        on the
        basis of a 360 day year and assessed for the actual number of days elapsed,
        and
        in such computation effect shall be given to any change in the interest rate
        resulting from a change in the Prime-based Rate on the date of such change
        in
        the Prime-based Rate.

      

      (b)           Interest
        on each Eurodollar-based Advance of the Revolving Credit shall accrue at
        its
        Eurodollar-based Rate and shall be payable in immediately available funds
        on the
        last day of the Eurodollar-Interest Period applicable thereto (and, if any
        Eurodollar-Interest Period shall exceed three months, then on the last Business
        Day of the third month of such Eurodollar-Interest Period, and at three month
        intervals thereafter). Interest accruing at the Eurodollar-based Rate shall
        be
        computed on the basis of a 360 day year and assessed for the actual number
        of
        days elapsed from the first day of the Eurodollar-Interest Period applicable
        thereto to but not including the last day thereof.

      (c)           Interest
        on each Quoted Rate Advance of the Swing Line shall accrue at its Quoted
        Rate
        and shall be payable in immediately available funds on the last day of the
        Interest Period applicable thereto. Interest accruing at the Quoted Rate
        shall
        be computed on the basis of a 360-day year and assessed for the actual number
        of
        days elapsed from the first day of the Interest Period applicable thereto
        to,
        but not including, the last day thereof.

      

      (d)           Notwithstanding
        anything to the contrary in the preceding sections, all accrued and unpaid
        interest on any Revolving Credit Advance refunded or converted pursuant to
        Section 2.3 hereof and any Swing Line Advance refunded pursuant to Section
        2.5(e) hereof, shall be due and payable in full on the date such Advance
        is
        refunded or converted.

      

      (e)           In
        the case of any Event of Default under Section 9.1(i), immediately upon the
        occurrence thereof, and in the case of any other Event of Default, immediately
        upon receipt by Agent of notice from the Majority Revolving Credit Lenders,
        interest shall be payable on demand on all Revolving Credit Advances and
        Swing
        Line Advances from time to time outstanding at a per annum rate equal to
        the
        Applicable Interest Rate in respect of each such Advance plus, in the case
        of
        Eurodollar-based Advances and Quoted Rate Advances, two percent (2%) for
        the
        remainder of the then existing Interest Period, if any, and at all other
        such
        times, and for all Prime-based Advances from time to time outstanding, at
        a per
        annum rate equal to the Prime-based Rate plus two percent (2%).

      

      2.7       
             Optional Prepayments.

      

      (a)           (i)
        The Borrowers may prepay all or part of the outstanding principal of any
        Prime-based Advance(s) of the Revolving Credit at any time, provided that,
        unless the “Sweep to Loan” system shall be in effect in respect of the Revolving
        Credit, after giving effect to any partial prepayment, the aggregate balance
        of
        Prime-based Advance(s) of the Revolving Credit remaining outstanding shall
        be at
        least One Million Dollars ($1,000,000), and (ii) subject to Section 2.10(c)
        hereof, the Borrowers may prepay all or part of the outstanding principal
        of any
        Eurodollar-based Advance of the Revolving Credit at any time (subject to
        not
        less than five (5) Business Day’s notice to Agent) provided that, after giving
        effect to any partial prepayment, the unpaid portion of such Advance which
        is to
        be refunded or converted under Section 2.3 hereof shall be at least Two Million
        Five Hundred Thousand Dollars ($2,500,000).

      

      (b)           (i)
        The Borrowers may prepay all or part of the outstanding principal of any
        Swing
        Line Advance carried at the Prime-based Rate at any time, provided that after
        giving effect to any partial prepayment, the aggregate balance of such
        Prime-based Swing Line Advances remaining outstanding shall be at least One
        Hundred Thousand Dollars ($100,000) and (ii) subject to Section 2.10(c) hereof,
        the Borrowers may prepay all or part of the outstanding principal of any

        than
        one (1) day’s notice to the Swing Line Lender) provided that after giving effect
        to any partial prepayment, the aggregate balance of such Quoted Rate Swing
        Line
        Advances remaining outstanding shall be at least Two Hundred Fifty Thousand
        Dollars ($250,000).

      (c)           Any
        prepayment of a Prime-based Advance made in accordance with this Section
        shall
        be without premium or penalty and any prepayment of any other type of Advance
        shall be subject to the provisions of Section 11.1 hereof, but otherwise
        without
        premium or penalty.

      

      2.8       
             Prime-based Advance in Absence of Election or
        Upon Default.  If, (a) as to any outstanding Eurodollar-based
        Advance of the Revolving Credit or any outstanding Quoted Rate Advance of
        the
        Swing Line, Agent has not received payment of all outstanding principal and
        accrued interest on the last day of the Interest Period applicable thereto,
        or
        does not receive a timely Request for Advance meeting the requirements of
        Section 2.3 or 2.5 hereof with respect to the refunding or conversion of
        such
        Advance, or (b) if on the last day of the
        applicable Interest Period a Default or an Event of Default shall have occurred
        and be continuing, then, on the last day of the applicable Interest Period
        the
        principal amount of any Eurodollar-based Advance or Quoted Rate Advance,
        as the
        case may be, which has not been prepaid shall, absent a contrary election
        of the
        Majority Revolving Credit Lenders, be converted automatically to a Prime-based
        Advance and the Agent shall thereafter promptly notify Borrowers of said
        action.  All accrued and unpaid interest on any Advance converted to a
        Prime-based Advance under this Section 2.8 shall be due and payable in full
        on
        the date such Advance is converted.

      

       

      2.9        
            Revolving Credit Facility
        Fee.  From the Effective Date to the Revolving Credit
        Maturity Date, the Borrowers shall pay, jointly and severally, to the Agent
        for
        distribution to the Lenders pro-rata in accordance with their respective
        Percentages, a Revolving Credit Facility Fee quarterly in arrears commencing
        January 1, 2008 and on the first day of each calendar quarter thereafter
        (in
        respect of the prior three months or any portion thereof). The Revolving
        Credit
        Facility Fee payable to each Lender shall be determined by multiplying the
        Applicable Fee Percentage times such Lender’s Revolving Credit Percentage of the
        Revolving Credit Aggregate Commitment then in effect (whether used or unused).
        The Revolving Credit Facility Fee shall be computed on the basis of a year
        of
        three hundred sixty (360) days and assessed for the actual number of days
        elapsed. Whenever any payment of the Revolving Credit Facility Fee shall
        be due
        on a day which is not a Business Day, the date for payment thereof shall
        be
        extended to the next Business Day. Upon receipt of such payment, Agent shall
        make prompt payment to each Lender of its share of the Revolving Credit Facility
        Fee based upon its respective Percentage. It is expressly understood that
        the
        Revolving Credit Facility Fees described in this Section are not
        refundable.

      

      2.10           Mandatory
        Repayment of Revolving Credit Advances.

      

      (a)           If
        at any time and for any reason the aggregate outstanding principal amount
        of
        Revolving Credit Advances plus Swing Line Advances, plus the outstanding
        Letter
        of Credit Obligations, shall exceed the Revolving Credit Aggregate Commitment,
        Borrowers shall immediately reduce any pending request for a Revolving Credit
        Advance on such day by the amount of such excess and, to the extent any excess
        remains thereafter, repay any Revolving Credit Advances and Swing Line Advances
        in an amount equal to the lesser of the outstanding amount of such Advances
        and
        the amount of such remaining excess, with such amounts to be applied between
        the
        Revolving Credit Advances and Swing Line Advances as determined by the Agent
        and
        then, to the extent that any excess remains after payment in full of all
        Revolving Credit Advances and Swing Line Advances, to provide cash collateral
        in
        support of any Letter of Credit Obligations in an amount equal to the lesser
        of
        (x) 105% of the amount of such Letter of Credit Obligations and (y) the amount
        of such remaining excess, with such cash collateral to be provided on the
        basis
        set forth in Section 9.2 hereof. Each Borrower acknowledges that, in connection
        with any repayment required hereunder, it shall also be responsible for the
        reimbursement of any prepayment or other costs required under Section 11.1
        hereof.  Any payments made pursuant to this Section shall be applied
        first to outstanding Prime-based Advances under the Revolving Credit, next
        to
        Swing Line Advances carried at the Prime-based Rate and then to Eurodollar-based
        Advances of the Revolving Credit, and then to Swing Line Advances carried
        at the
        Quoted Rate.

      (b)           Intentionally
        omitted.

      

      (c)           To
        the extent that, on the date any mandatory repayment of the Revolving Credit
        Advances under this Section 2.10 or payment pursuant to the terms of any
        of the
        Loan Documents is due, the Indebtedness under the Revolving Credit or any
        other
        Indebtedness to be prepaid is being carried, in whole or in part, at the
        Eurodollar-based Rate and no Default or Event of Default has occurred and
        is
        continuing, Borrowers may deposit the amount of such mandatory prepayment
        in a
        cash collateral account to be held by the Agent, for and on behalf of the
        Revolving Credit Lenders, on such terms and conditions as are reasonably
        acceptable to Agent and upon such deposit the obligation of Borrowers to
        make
        such mandatory prepayment shall be deemed satisfied. Subject to the terms
        and
        conditions of said cash collateral account, sums on deposit in said cash
        collateral account shall be applied (until exhausted) to reduce the principal
        balance of the Revolving Credit on the last day of each Eurodollar-Interest
        Period attributable to the Eurodollar-based Advances of such Revolving Advance,
        thereby avoiding breakage costs under Section 11.1 hereof; provided, however,
        that if a Default or Event of Default shall have occurred at any time while
        sums
        are on deposit in the cash collateral account, Agent may, in its sole
        discretion, elect to apply such sums to reduce the principal balance of such
        Eurodollar-based Advances prior to the last day of the applicable
        Eurodollar-Interest Period, and the Borrowers will be obligated to pay any
        resulting breakage costs under Section 11.1.

      

      2.11           Optional
        Reduction or Termination of Revolving Credit Aggregate Commitment.
Borrowers may, upon at least five (5) Business Days’ prior written notice to
        the Agent, permanently reduce the Revolving Credit Aggregate Commitment in
        whole
        at any time, or in part from time to time, without premium or penalty, provided
        that: (i) each partial reduction of the Revolving Credit Aggregate Commitment
        shall be in an aggregate amount equal to One Million Dollars ($1,000,000)
        or a
        larger integral multiple of One Hundred Thousand Dollars ($100,000); (ii)
        each
        reduction shall be accompanied by the payment of the Revolving Credit Facility
        Fee, if any, accrued and unpaid to the date of such reduction; (iii) Borrowers
        shall prepay in accordance with the terms hereof the amount, if any, by which
        the aggregate unpaid principal amount of Revolving Credit Advances and Swing
        Line Advances (including, without duplication, any deemed Advances made under
        Section 3.6 hereof) outstanding hereunder, plus the Letter of Credit
        Obligations, exceeds the amount of the then applicable Revolving Credit
        Aggregate Commitment as so reduced, together with interest thereon to the
        date
        of prepayment; (iv) no reduction shall reduce the Revolving Credit Aggregate
        Commitment to an amount which is less than the aggregate undrawn amount of
        any
        Letters of Credit outstanding at such time; and (v) no such reduction shall
        reduce the Swing Line Maximum Amount unless Borrowers so elect, provided
        that
        the Swing Line Maximum Amount shall at no time be greater than the Revolving
        Credit Aggregate Commitment; provided, however that if the termination or
        reduction of the Revolving Credit Aggregate Commitment requires the prepayment
        of a Eurodollar-based Advance or a Quoted Rate Advance and such termination
        or
        reduction is made on a day other than the last Business Day of the then current
        Interest Period applicable to such Eurodollar-based Advance or such Quoted
        Rate
        Advance, then, pursuant to Section 11.1, Borrowers shall compensate the
        Revolving Credit Lenders and/or the Swing Line Lender for any losses or,
        so long
        as no Default or Event of Default has occurred and is continuing, Borrowers
        may
        deposit the amount of such prepayment in a collateral account as provided
        in
        Section 2.10(c). Reductions of the Revolving Credit Aggregate Commitment
        and any
        accompanying prepayments of Advances of the Revolving Credit shall be
        distributed by Agent to each Revolving Credit Lender in accordance with such
        Revolving Credit Lender’s Revolving Percentage thereof, and will not be
        available for reinstatement by or readvance to Borrowers and any accompanying
        prepayments of Advances of the Swing Line shall be distributed by Agent to
        the
        Swing Line Lender and will not be available for reinstatement by or readvance
        to
        the Borrowers. Any reductions of the Revolving Credit Aggregate Commitment
        hereunder shall reduce each Revolving Credit Lender’s portion thereof
        proportionately (based on the applicable Percentages), and shall be permanent
        and irrevocable. Any payments made pursuant to this Section shall be applied
        first to outstanding Prime-based Advances under the Revolving Credit, next
        to
        Swing Line Advances carried at the Prime-based Rate and then to Eurodollar-based
        Advances of the Revolving Credit, and then to Swing Line Advances carried
        at the
        Quoted Rate.

      3.1        
            Letters of Credit.  Subject to the
        terms and conditions of this Agreement, Issuing Lender may through the Issuing
        Office, at any time and from time to time from and after the date hereof
        until
        thirty (30) days prior to the Revolving Credit Maturity Date, upon the written
        request of Borrowers accompanied by a duly executed Letter of Credit Agreement
        and such other documentation related to the requested Letter of Credit as
        the
        Issuing Lender may require, issue Letters of Credit in Dollars for the account
        of Borrowers, in an aggregate amount for all Letters of Credit issued hereunder
        at any one time outstanding not to exceed the Letter of Credit Maximum Amount.
        Each Letter of Credit shall be in a minimum face amount of One Hundred Thousand
        Dollars ($100,000) (or such lesser amount as may be agreed to by Issuing
        Lender)
        and each Letter of Credit (including any renewal thereof) shall expire not
        later
        than the first to occur of (i) thirteen months after the date of issuance
        thereof and (ii) ten (10) Business Days prior to the Revolving Credit Maturity
        Date in effect on the date of issuance thereof, provided, however, with the
        consent of the Issuing Lender, a Letter of Credit may provide that such Letter
        of Credit shall automatically renew at the end of such term unless Issuing
        Lender shall have given written notice at least thirty (30) days prior to
        the
        expiration of such Letter of Credit.  The submission of all
        applications in respect of and the issuance of each Letter of Credit hereunder
        shall be subject in all respects to the International Standby Practices 98,
        and
        any successor documentation thereto and to the extent not inconsistent
        therewith, the laws of the State of Michigan. In the event of any conflict
        between this Agreement and any Letter of Credit Document other than any Letter
        of Credit, this Agreement shall control.

                  order, judgment or decree of any court, arbitrator or governmental

                Issuing

                  the issuance of such Letter of Credit pursuant to Section 3.4

        constitute the certification by Borrowers of the matters set forth in Sections

        any duty of inquiry.

      

      3.3      
              Notice.  The Issuing
        Lender shall deliver to the Agent, concurrently with or promptly following
        its
        issuance of any Letter of Credit, a true and complete copy of each Letter
        of

                (i)

              	
                A
                  per annum letter of credit fee with respect to the undrawn amount
                  of each
                  Letter of Credit issued pursuant hereto (based on the amount of
                  each
                  Letter of Credit) in the amount of the Applicable Fee Percentage
                  (determined with reference to Schedule 1.1 to this Agreement) shall
                  be
                  paid to the Agent for distribution to the Revolving Credit Lenders
                  in
                  accordance with their Percentages.

              

      

      

      
        	
                 

              	
                (ii)

              	
                A
                  letter of credit facing fee on the face amount of each Letter of
                  Credit
                  shall be paid to the Agent for distribution to the Issuing Lender
                  for its
                  own account, in accordance with the terms of the applicable Fee
                  Letter.

              

      

      

      
        	
                 

              	
                (b)

              	
                All
                  payments by Borrowers to the Agent for distribution to the Issuing
                  Lender
                  or the Revolving Credit Lenders under this Section 3.4 shall be
                  made in
                  Dollars in immediately available funds at the Issuing Office or
                  such other
                  office of the Agent as may be designated from time to time by written
                  notice to Borrowers by the Agent. The fees described in clauses
                  (a)(i) and
                  (ii) above (i) shall be nonrefundable under all circumstances,
                  (ii) in the
                  case of fees due under clause (a)(i) above, shall be payable semi-annually
                  in advance and (iii) in the case of fees due under clause (a)(ii)
                  above,
                  shall be payable upon the issuance of such Letter of Credit and
                  upon any
                  amendment thereto or extension thereof.  The fees due under
                  clause (a)(i) above shall be determined by multiplying the Applicable
                  Fee
                  Percentage times the undrawn amount of the face amount of each
                  such Letter
                  of Credit on the date of determination, and shall be calculated
                  on the
                  basis of a 360 day year and assessed for the actual number of days
                  from
                  the date of the issuance thereof to the stated expiration thereof.
                  The
                  parties hereto acknowledge that, unless the Issuing Lender otherwise
                  agrees, any material amendment and any extension to a Letter of
                  Credit
                  issued hereunder shall be treated as a new Letter of Credit for
                  the
                  purposes of the letter of credit facing
                  fee.

                (c)

              	
                If
                  any change in any law or regulation or in the interpretation thereof
                  by
                  any court or administrative or governmental authority charged with
                  the
                  administration thereof, adopted after the date hereof, shall either
                  (i)
                  impose, modify or cause to be deemed applicable any reserve, special
                  deposit, limitation or similar requirement against letters of credit
                  issued or participated in by, or assets held by, or deposits in
                  or for the
                  account of, Issuing Lender or any Revolving Credit Lender or (ii)
                  impose
                  on Issuing Lender or any Revolving Credit Lender any other condition
                  regarding this Agreement, the Letters of Credit or any participations
                  in
                  such Letters of Credit, and the result of any event referred to
                  in clause
                  (i) or (ii) above shall be to increase the cost or expense to Issuing
                  Lender or such Revolving Credit Lender of issuing or maintaining
                  or
                  participating in any of the Letters of Credit (which increase in
                  cost or
                  expense shall be determined by the Issuing Lender’s or such Revolving
                  Credit Lender’s reasonable allocation of the aggregate of such cost
                  increases and expenses resulting from such events), then, upon
                  demand by
                  the Issuing Lender or such Revolving Credit Lender, as the case
                  may be,
                  Borrowers shall, within thirty (30) days following demand for payment,
                  pay
                  to Issuing Lender or such Revolving Credit Lender, as the case
                  may be,
                  from time to time as specified by the Issuing Lender or such Revolving
                  Credit Lender, additional amounts which shall be sufficient to
                  compensate
                  the Issuing Lender or such Revolving Credit Lender for such increased
                  cost
                  and expense (together with interest on each such amount from ten
                  days
                  after the date such payment is due until payment in full thereof
                  at the
                  Prime-based Rate), provided that if the Issuing Lender or such
                  Revolving
                  Credit Lender could take any reasonable action, without cost or
                  administrative or other burden or restriction to such Lender, to
                  mitigate
                  or eliminate such cost or expense, it agrees to do so within a
                  reasonable
                  time after becoming aware of the foregoing matters. Each demand
                  for
                  payment under this Section 3.4(c) shall be accompanied by a certificate
                  of
                  Issuing Lender or the applicable Revolving Credit Lender setting
                  forth the
                  amount of such increased cost or expense incurred by the Issuing
                  Lender or
                  such Revolving Credit Lender, as the case may be, as a result of
                  any event
                  mentioned in clause (i) or (ii) above, and in reasonable detail,
                  the
                  methodology for calculating and the calculation of such amount,
                  which
                  certificate shall be prepared in good faith and shall be conclusive
                  evidence, absent manifest error, as to the amount
                  thereof.

      3.5      
              Other Fees.  In connection
        with the Letters of Credit, and in addition to the Letter of Credit Fees,
        Borrowers shall pay, for the sole account of the Issuing Lender, standard
        documentation, administration, payment and cancellation charges assessed
        by
        Issuing Lender or the Issuing Office, at the times, in the amounts and on
        the
        terms set forth or to be set forth from time to time in the standard fee
        schedule of the Issuing Office in effect from time to time.

      

      3.6      
              Drawings and Demands for Payment Under
        Letters of Credit.

      

      (a)           If
        the Issuing Lender shall honor a draft or other demand for payment presented
        or
        made under any Letter of Credit, each Borrower agrees to pay to the Issuing
        Lender an amount equal to the amount paid by the Issuing Lender in respect
        of
        such draft or other demand under such Letter of Credit and all reasonable
        expenses paid or incurred by the Agent relative thereto not later than 1:00
        p.m.
        (Detroit time), on (i) the Business Day that Borrowers receive notice of
        such
        presentment and honor, if such notice is received prior to 11:00 a.m. (Detroit
        time) or (ii) the Business Day immediately following the day that Borrowers
        received such notice, if such notice is received after 11:00 a.m. (Detroit
        time). Unless Borrowers shall have made such payment to the Agent for the
        account of the Issuing Lender on such day, the Agent shall be deemed to have
        disbursed to Borrowers and to have elected to substitute for the reimbursement
        obligation, with respect to the applicable Letter of Credit honored by the
        Issuing Lender, a Prime-based Advance of the Revolving Credit (which Advance
        may
        be subsequently converted at any time into a Eurodollar-based Advance pursuant
        to Section 2.3 hereof) on behalf of and for the account of the Revolving
        Credit
        Lenders in an aggregate amount equal to the amount so paid by the Issuing
        Lender
        in respect of such draft or other demand under such Letter of Credit. Such
        Prime-based Advance shall be deemed disbursed notwithstanding any failure
        to
        satisfy any conditions for disbursement of any Advance set forth in Section
        2
        hereof and, to the extent of the Advances so disbursed, the reimbursement
        obligation of Borrowers under this Section 3.6 shall be deemed
        satisfied.

      

      (b)           If
        the Issuing Lender shall honor a draft or other demand for payment presented
        or
        made under any Letter of Credit, the Issuing Lender shall provide notice
        thereof
        to Borrowers on the date such draft or demand is honored, and to each Revolving
        Credit Lender on such date unless Borrowers shall have satisfied their
        reimbursement obligations under Section 3.6(a) hereof by payment to the Agent
        (for the benefit of the Issuing Lender) on such date. The Issuing Lender
        shall
        further use reasonable efforts to provide notice to Borrowers prior to honoring
        any such draft or other demand for payment, but such notice, or the failure
        to
        provide such notice, shall not affect the rights or obligations of the Issuing
        Lender with respect to any Letter of Credit or the rights and obligations
        of the
        parties hereto, including without limitation the obligations of Borrowers
        under
        Section 3.6(a) hereof.

      (c)           Upon
        issuance by the Issuing Lender of each Letter of Credit hereunder, each
        Revolving Credit Lender shall automatically acquire a pro rata participation
        interest in such Letter of Credit and each related Letter of Credit Payment
        based on its respective Revolving Credit Percentage. Each Revolving Credit
        Lender, on the date a draft or demand under any Letter of Credit is honored
        (or
        the next succeeding Business Day if the notice required to be given by Issuing
        Lender to the Revolving Credit Lenders under Section 3.6(b) hereof is not
        given
        to the Revolving Credit Lenders prior to 2:00 p.m. (Detroit time) on such
        date
        of draft or demand), shall make its Revolving Credit Percentage of the amount
        paid by the Issuing Lender, and not reimbursed by Borrowers on such day,
        in
        immediately available funds at the principal office of the Agent for the
        account
        of Issuing Lender. If and to the extent such Revolving Credit Lender shall
        not
        have made such pro rata portion available to the Agent, such Revolving Credit
        Lender agrees to pay to the Agent for the account of the Issuing Lender
        forthwith on demand such amount together with interest thereon, for each
        day
        from the date such amount was paid by the Issuing Lender until such amount
        is so
        made available to the Agent at the Federal Funds Rate for the first three
        days
        and thereafter at a Prime-based Rate applicable during such period to the
        related Advance deemed to have been disbursed under Section 3.6(a) in respect
        of
        the reimbursement obligation of Borrowers.  If such Revolving Credit
        Lender shall pay such amount to the Agent for the account of Issuing Lender
        together with such interest, if any, such amount so paid shall be deemed
        to
        constitute an Advance by such Revolving Credit Lender disbursed in respect
        of
        the reimbursement obligation of Borrowers under Section 3.6(a) hereof for
        purposes of this Agreement, effective as of the dates applicable under said
        Section 3.6(a). The failure of any Revolving Credit Lender to make its pro
        rata
        portion of any such amount paid by the Issuing Lender available to the Agent
        for
        the account of Issuing Lender shall not relieve any other Revolving Credit
        Lender of its obligation to make available its pro rata portion of such amount,
        but no Revolving Credit Lender shall be responsible for failure of any other
        Revolving Credit Lender to make such pro rata portion available to the Agent
        for
        the account of Issuing Lender.

      

      Notwithstanding
        the foregoing however no Revolving Credit Lender shall be deemed to have
        acquired a participation in a Letter of Credit if the officers of the Issuing
        Lender immediately responsible for matters concerning this Agreement shall
        have
        received written notice from Agent or any Lender at least two (2) Business
        Days
        prior to the date of the issuance of such Letter of Credit that the issuance
        of
        Letters of Credit should be suspended based on the occurrence and continuance
        of
        a Default or Event of Default and stating that such notice is a “notice of
        default”; provided, however that the Revolving Credit Lenders shall be deemed to
        have acquired such a participation upon the date on which such Default or
        Event
        of Default has been waived by the requisite Revolving Credit Lenders, as
        applicable.  In the event that the Issuing Lender receives such a
        notice, the Issuing Lender shall have no obligation to issue any Letter of
        Credit until such notice is withdrawn by Agent or such Lender or until the
        requisite Lenders have waived such Default or Event of Default in accordance
        with the terms of this Agreement.

      

      (d)           Nothing
        in this Agreement shall be construed to require or authorize any Revolving
        Credit Lender to issue any Letter of Credit, it being recognized that the
        Issuing Lender shall be the sole issuer of Letters of Credit under this
        Agreement.

      

      3.7            Obligations
        Irrevocable.  The obligations of Borrowers to make payments to
        Agent for the account of Issuing Lender or the Revolving Credit Lenders with
        respect to Letter of Credit Obligations under Section 3.6 hereof, shall be
        unconditional and irrevocable and not subject to any qualification or exception
        whatsoever, including, without limitation:

                Any
                  amendment, modification, waiver, consent, or any substitution,
                  exchange or
                  release of or failure to perfect any interest in collateral or
                  security,
                  with respect to or under any Letter of Credit

                (c)

              	
                The
                  existence of any claim, setoff, defense or other right which Borrowers
                  may
                  have at any time against any beneficiary or any transferee of any

                  such transferee may be acting), the Agent, the Issuing Lender or
                  any
                  Revolving Credit Lender or any other Person, whether in connection
                  with
                  this Agreement, any of the Letter of Credit Documents, the transactions
                  contemplated herein or therein or any unrelated

                  by the Issuing Lender to the beneficiary under any Letter of Credit
                  against presentation of documents which do not comply with the
                  terms of
                  such Letter of Credit, including failure of any documents to bear
                  any
                  reference or adequate reference to such Letter of
                  Credit;

              

      

      

      
        	
                 

              	
                (f)

              	
                Any
                  failure, omission, delay or lack on the part of the Agent, Issuing
                  Lender
                  or any Revolving Credit Lender or any party to any of the Letter
                  of Credit
                  Documents to enforce, assert or exercise any right, power or remedy
                  conferred upon the Agent, Issuing Lender, any Revolving Credit

                  or any

                (g)

              	
                Any
                  other event or circumstance that would, in the absence of this
                  Section
                  3.7, result in the release or discharge by operation of law or
                  otherwise
                  of Borrowers from the performance or observance of any obligation,
                  covenant or agreement contained in Section 3.6
                  hereof.

              

      

      

      No
        setoff, counterclaim, reduction or diminution of any obligation or any defense
        of any kind or nature which any Borrower has or may have against the beneficiary
        of any Letter of Credit shall be available hereunder to such Borrower against
        the Agent, Issuing Lender or any Revolving Credit Lender. With respect to
        any
        Letter of Credit, nothing contained in this Section 3.7 shall be deemed to
        prevent any Borrower, after satisfaction in full of the absolute and
        unconditional obligations of Borrowers hereunder with respect to such Letter
        of
        Credit, from asserting in a separate action any claim, defense, set off or
        other
        right which they (or any of them) may have against Agent, Issuing Lender
        or any
        Revolving Credit Lender in connection with such Letter of
        Credit.

      3.8          
          Risk Under Letters of Credit.

      

      (a)           In
        the administration and handling of Letters of Credit and any security therefor,
        or any documents or instruments given in connection therewith, Issuing Lender
        shall have the sole right to take or refrain from taking any and all actions
        under or upon the Letters of Credit.

      

      (b)           Subject
        to other terms and conditions of this Agreement, Issuing Lender shall issue
        the
        Letters of Credit and shall hold the documents related thereto in its own
        name
        and shall make all collections thereunder and otherwise administer the Letters
        of Credit in accordance with Issuing Lender’s regularly established practices
        and procedures and will have no further obligation with respect thereto.
        In the
        administration of Letters of Credit, Issuing Lender shall not be liable for
        any
        action taken or omitted on the advice of counsel, accountants, appraisers
        or
        other experts selected by Issuing Lender with due care and Issuing Lender
        may
        rely upon any notice, communication, certificate or other statement from
        Borrowers, beneficiaries of Letters of Credit, or any other Person which
        Issuing
        Lender believes to be authentic. Issuing Lender will, upon request, furnish
        the
        Revolving Credit Lenders with copies of Letter of Credit Documents related
        thereto.

      

      (c)           In
        connection with the issuance and administration of Letters of Credit and
        the
        assignments hereunder, Issuing Lender makes no representation and shall have
        no
        responsibility with respect to (i) the obligations of Borrowers or the validity,
        sufficiency or enforceability of any document or instrument given in connection
        therewith, or the taking of any action with respect to same, (ii) the financial
        condition of, any representations made by, or any act or omission of Borrowers
        or any other Person, or (iii) any failure or delay in exercising any rights
        or
        powers possessed by Issuing Lender in its capacity as issuer of Letters of
        Credit in the absence of its gross negligence or willful misconduct. Each
        of the
        Revolving Credit Lenders expressly acknowledges that it has made and will
        continue to make its own evaluations of Borrowers’ creditworthiness without
        reliance on any representation of Issuing Lender or Issuing Lender’s officers,
        agents and employees.

      

      (d)           If
        at any time Issuing Lender shall recover any part of any unreimbursed amount
        for
        any draw or other demand for payment under a Letter of Credit, or any interest
        thereon, Agent or Issuing Lender, as the case may be, shall receive same
        for the
prorata benefit of the Revolving Credit Lenders in accordance with
        their respective Percentages and shall promptly deliver to each Revolving
        Credit
        Lender its share thereof, less such Revolving Credit Lender’s pro rata share of
        the costs of such recovery, including court costs and attorney’s fees. If at any
        time any Revolving Credit Lender shall receive from any source whatsoever
        any
        payment on any such unreimbursed amount or interest thereon in excess of
        such
        Revolving Credit Lender’s Percentage of such payment, such Revolving Credit
        Lender will promptly pay over such excess to Agent, for redistribution in
        accordance with this Agreement.

      

      3.9        
            Indemnification.  Each Borrower
        hereby indemnifies and agrees to hold harmless the Revolving Credit Lenders,
        the
        Issuing Lender and the Agent and their respective Affiliates, and the respective
        officers, directors, employees and agents of such Persons (each an “L/C
        Indemnified Person”), from and against any and all claims, damages, losses,
        liabilities, costs or expenses of any kind or nature whatsoever which the
        Revolving Credit Lenders, the Issuing Lender or the Agent or any such Person
        may
        incur or which may be claimed against any of them by reason of or in connection
        with any Letter of Credit (collectively, the “L/C Indemnified Amounts”), and
        none of the Issuing Lender, any Revolving Credit Lender or the Agent or any
        of
        their respective officers, directors, employees or agents shall be liable
        or
        responsible for:

                (a)

              	
                the
                  use which may be made of any Letter of Credit or for any acts or
                  omissions
                  of any beneficiary in connection
                  therewith;

              

      

      

      
        	
                 

              	
                (b)

              	
                the
                  validity, sufficiency or genuineness of documents or of any endorsement
                  thereon, even if such documents should in fact prove to be in any
                  or all
                  respects invalid, insufficient, fraudulent or
                  forged;

              

      

      

      
        	
                 

              	
                (c)

              	
                payment
                  by the Issuing Lender to the beneficiary under any Letter of Credit
                  against presentation of documents which do not strictly comply
                  with the
                  terms of any Letter of Credit (unless such payment resulted from
                  the gross
                  negligence or willful misconduct of the Issuing Lender), including
                  failure
                  of any documents to bear any reference or adequate reference to
                  such
                  Letter of Credit;

              

      

      

      
        	
                 

              	
                (d)

              	
                any
                  error, omission, interruption or delay in transmission, dispatch
                  or
                  delivery of any message or advice, however transmitted, in connection
                  with
                  any Letter of Credit; or

              

      

      

      
        	
                 

              	
                (e)

              	
                any
                  other event or circumstance whatsoever arising in connection with
                  any
                  Letter of Credit.

              

      

      

      It
        is
        understood that in making any payment under a Letter of Credit the Issuing
        Lender will rely on documents presented to it under such Letter of Credit
        as to
        any and all matters set forth therein without further investigation and
        regardless of any notice or information to the contrary.

      

      With
        respect to subparagraphs (a) through (e) hereof, (i) no Borrower shall be
        required to indemnify any L/C Indemnified Person for any L/C Indemnified
        Amounts
        to the extent such amounts result from the gross negligence or willful
        misconduct of such L/C Indemnified Person or any officer, director, employee
        or
        agent of such L/C Indemnified Person and (ii) the Agent and the Issuing Lender
        shall be liable to each Borrower to the extent, but only to the extent, of
        any
        direct, as opposed to consequential or incidental, damages suffered by such
        Borrower which were caused by the gross negligence or willful misconduct
        of the
        Issuing Lender or any officer, director, employee or agent of the Issuing
        Lender
        or by the Issuing Lender’s wrongful dishonor of any Letter of Credit after the
        presentation to it by the beneficiary thereunder of a draft or other demand
        for
        payment and other documentation strictly complying with the terms and conditions
        of such Letter of Credit.

      

      3.10           Right
        of Reimbursement.  Each Revolving Credit Lender agrees to
        reimburse the Issuing Lender on demand, pro rata in accordance with its
        respective Revolving Credit Percentage, for (i) the reasonable out-of-pocket
        costs and expenses of the Issuing Lender to be reimbursed by Borrowers pursuant
        to any Letter of Credit Agreement or any Letter of Credit, to the extent
        not
        reimbursed by Borrowers or any other Credit Party and (ii) any and all
        liabilities, obligations, losses, damages, penalties, actions, judgments,
        suits,
        costs, fees, reasonable out-of-pocket expenses or disbursements of any kind
        and
        nature whatsoever which may be imposed on, incurred by or asserted against
        Issuing Lender in any way relating to or arising out of this Agreement
        (including Section 3.6(c) hereof), any Letter of Credit, any documentation
        or
        any transaction relating thereto, or any Letter of Credit Agreement, to the
        extent not reimbursed by Borrowers, except to the extent that such liabilities,
        losses, costs or expenses were incurred by Issuing Lender as a result of
        Issuing
        Lender’s gross negligence or willful misconduct or by the Issuing Lender’s
        wrongful dishonor of any Letter of Credit after the presentation to it by
        the
        beneficiary thereunder of a draft or other demand for payment and other

        otherwise) of Borrowers or any other Credit Party; and (e) there shall have
        been
        no material adverse change to the pro forma financial information and
        projections delivered to Agent prior to the execution and delivery of the
        Commitment Letter.

      5.2            Continuing
        Conditions.  The obligations of each Lender to make
        Advances (including the initial Advance) under this Agreement and the obligation
        of the Issuing Lender to issue any Letters of Credit shall be subject to
        the
        continuing conditions that:

      

      (a)           No
        Default or Event of Default shall exist as of the date of the Advance or
        the
        request for the Letter of Credit, as the case may be; and

      

      (b)           Each
        of the representations and warranties contained in this Agreement and in
        each of
        the other Loan Documents shall be true and correct in all material respects
        as
        of the date of the Advance or Letter of Credit (as the case may be) as if
        made
        on and as of such date (other than any representation or warranty that expressly
        speaks only as of a different date).

      

      
        	
                6.

              	
                REPRESENTATIONS
                  AND WARRANTIES.

              

      

      

      Each
        Borrower represents and warrants to the Agent, the Lenders, the Swing Line
        Lender and the Issuing Lender as follows:

      

      6.1            Corporate
        Authority.  Each Credit Party is a corporation (or other
        business entity) duly organized and existing in good standing under the laws
        of
        the state or jurisdiction of its incorporation or formation, as applicable,
        and
        each Credit Party is duly qualified and authorized to do business as a foreign
        corporation in each jurisdiction where the character of its assets or the
        nature
        of its activities makes such qualification and authorization necessary except
        where failure to be so qualified or be in good standing could not reasonably
        be
        expected to have a Material Adverse Effect. Each Credit Party has all requisite
        corporate, limited liability or partnership power and authority to own all
        its
        property (whether real, personal, tangible or intangible or of any kind
        whatsoever) and to carry on its business.

      

      6.2            Due
        Authorization.  Execution, delivery and performance of this
        Agreement, and the other Loan Documents, to which each Credit Party is party,
        and the issuance of the Notes by Borrowers (if requested) are within such
        Person’s corporate, limited liability or partnership power, have been duly
        authorized, are not in contravention of any law applicable to such Credit
        Party
        or the terms of such Credit Party’s organizational documents and, except as have
        been previously obtained or as referred to in Section 6.10, below, do not
        require the consent or approval of any governmental body, agency or authority
        or
        any other third party except to the extent that such consent or approval
        is not
        material to the transactions contemplated by the Loan Documents.

      

      6.3            Good
        Title; Leases; Assets; No Liens.  (a)  Each
        Credit Party, to the extent applicable, has good and valid title (or, in
        the
        case of real property, good and marketable title) to all assets owned by
        it,
        subject only to the Liens permitted under section 8.2 hereof, and each Credit
        Party has a valid leasehold or interest as a lessee or a licensee in all
        of its
        leased real property;

      

      (b)           Schedule
        6.3(b) hereof identifies all of the real property owned by the Credit Parties
        on
        the Effective Date;

      
        
          
          

        

        
          50

          
            

          

        

        
          
          

        

      

      (c)         
           The Credit Parties will collectively own or collectively have
        a valid leasehold interest in all assets that were owned or leased (as lessee)
        by the Credit Parties immediately prior to the Effective Date to the extent
        that
        such assets are necessary for the continued operation of the Credit Parties’
businesses in substantially the manner as such businesses were operated
        immediately prior to the Effective Date;

      

      (d)          
          Each Credit Party owns or has a valid leasehold interest in all real
        property necessary for its continued operations and, to the best knowledge
        of
        Borrowers, no material condemnation, eminent domain or expropriation action
        has
        been commenced or threatened against any such owned or leased real property;
        and

      

      (e)        
            There are no Liens on and no financing statements on
        file with respect to any of the assets owned by the Credit Parties, except
        for
        the Liens permitted pursuant to Section 8.2 of this Agreement.

      

      6.4      
              Taxes.  Except as
        set forth on Schedule 6.4 hereof, each Credit Party has filed on or before
        their
        respective due dates or within the applicable grace periods, all United States
        federal, state, local and other tax returns which are required to be filed
        or
        has obtained extensions for filing such tax returns and is not delinquent
        in
        filing such returns in accordance with such extensions and has paid all material
        taxes which have become due pursuant to those returns or pursuant to any
        assessments received by any such Credit Party, as the case may be, to the
        extent
        such taxes have become due, except to the extent such taxes are being contested
        in good faith by appropriate proceedings diligently conducted and with respect
        to which adequate provision has been made on the books of such Credit Party
        as
        may be required by GAAP.

      

      6.5        
            No Defaults.  No Credit Party is
        in default under or with respect to any agreement, instrument or undertaking
        to
        which it is a party or by which it or any of its property is bound which
        would
        cause or would reasonably be expected to cause a Material Adverse
        Effect.

      

      6.6         
           Enforceability of Agreement and Loan
        Documents.  This Agreement and each of the other Loan
        Documents to which any Credit Party is a party (including without limitation,
        each Request for Advance), have each been duly executed and delivered by
        its
        duly authorized officers and constitute the valid and binding obligations
        of
        such Credit Party, enforceable against such Credit Party in accordance with
        their respective terms, except as enforcement thereof may be limited by
        applicable bankruptcy, reorganization, insolvency, fraudulent conveyance,
        moratorium or similar laws affecting the enforcement of creditor’s rights,
        generally and by general principles of equity (regardless of whether enforcement
        is considered in a proceeding in law or equity).

      

      6.7        
            Compliance with Laws.  (a)
        Except as disclosed on Schedule 6.7, each Credit Party has complied with
        all
        applicable federal, state and local laws, ordinances, codes, rules, regulations
        and guidelines (including consent decrees and administrative orders) including
        but not limited to Hazardous Material Laws, and is in compliance with any
        Requirement of Law, except to the extent that failure to comply therewith
        could
        not reasonably be expected to have a Material Adverse Effect; and (b) neither
        the extension of credit made pursuant to this Agreement or the use of the
        proceeds thereof by the Credit Parties will violate the Trading with the
        Enemy
        Act, as amended, or any of the foreign assets control regulations of the
        United
        States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or
        any
        enabling legislation or executive order relating thereto, or The United and
        Strengthening America by providing appropriate Tools Required to Intercept
        and
        Obstruct Terrorism (“USA Patriot Act”) Act of 2001, Public Law 10756, October
        26, 2001 or  Executive Order 13224 of September 23, 2001 issued by the
        President of the United States (66 Fed. Reg. 49049 (2001)).

      
        
          
          

        

        
          51

          
            

          

        

        
          
          

        

      

      6.8        
            Non-contravention.  The
        execution, delivery and performance of this Agreement and the other Loan
        Documents (including each Request for Advance) to which each Credit Party
        is a
        party are not in contravention of the terms of any indenture, agreement or
        undertaking to which such Credit Party is a party or by which it or its
        properties are bound where such violation could reasonably be expected to
        have a
        Material Adverse Effect.

      

      6.9        
            Litigation.  Except as set forth
        on Schedule 6.9 hereof, there is no suit, action, proceeding, including,
        without
        limitation, any bankruptcy proceeding or governmental investigation pending
        against or to the knowledge of Borrowers, threatened against any Credit Party
        (other than any suit, action or proceeding in which a Credit Party is the
        plaintiff and in which no counterclaim or cross-claim against such Credit
        Party
        has been filed), or any judgment, decree, injunction, rule, or order of any
        court, government, department, commission, agency, instrumentality or arbitrator
        outstanding against any Credit Party, nor is any Credit Party in violation
        of
        any applicable law, regulation, ordinance, order, injunction, decree or
        requirement of any governmental body or court which could in any of the
        foregoing events reasonably be expected to have a Material Adverse
        Effect.

      

      6.10           Consents,
        Approvals and Filings, Etc.  Except as set forth on
        Schedule 6.10 hereof, no material authorization, consent, approval, license,
        qualification or formal exemption from, nor any filing, declaration or
        registration with, any court, governmental agency or regulatory authority
        or any
        securities exchange or any other Person (whether or not governmental) is
        required in connection with the execution, delivery and performance: (a)
        by any
        Credit Party of this Agreement and any of the other Loan Documents or
        Acquisition Documents to which such Credit Party is a party or (b) by the
        Credit
        Parties of the grant of Liens granted, conveyed or otherwise established
        (or to
        be granted, conveyed or otherwise established) by or under this Agreement
        or the
        other Loan Documents, as applicable, except in each case for (i) such matters
        which have been previously obtained, and (ii) such filings to be made
        concurrently herewith or promptly following the Effective Date as are required
        by the Collateral Documents to perfect Liens in favor of the Agent. All such
        material authorizations, consents, approvals, licenses, qualifications,
        exemptions, filings, declarations and registrations which have previously
        been
        obtained or made, as the case may be, are in full force and effect and, to
        the
        best knowledge of Borrowers, are not the subject of any attack or threatened
        attack (in each case in any material respect) by appeal or direct proceeding
        or
        otherwise.

      

      6.11           Agreements
        Affecting Financial Condition.  No Credit Party is party to
        any agreement or instrument or subject to any charter or other corporate
        restriction which could reasonably be expected to have a Material Adverse
        Effect.

      

      6.12           No
        Investment Company or Margin Stock.  No Credit Party is an
“investment company” within the meaning of the Investment Company Act of 1940,
        as amended. No Credit Party is engaged principally, or as one of its important
        activities, directly or indirectly, in the business of extending credit for
        the
        purpose of purchasing or carrying margin stock. None of the proceeds of any
        of
        the Advances will be used by any Credit Party to purchase or carry margin
        stock.
        Terms for which meanings are provided in Regulation U of the Board of Governors
        of the Federal Reserve System or any regulations substituted therefore, as
        from
        time to time in effect, are used in this paragraph with such
        meanings.

      
        
          
          

        

        
          52

          
            

          

        

        
          
          

        

      

      6.13           ERISA.  No
        Credit Party maintains or contributes to any Pension Plan subject to Title
        IV of
        ERISA, except as set forth on Schedule 6.13 hereto or otherwise disclosed
        to the
        Agent in writing.  There is no accumulated funding deficiency within
        the meaning of Section 412 of the Internal Revenue Code or Section 302 of
        ERISA,
        or any outstanding liability with respect to any Pension Plans owed to the
        PBGC
        other than future premiums due and owing pursuant to Section 4007 of ERISA,
        and
        no “reportable event” as defined in Section 4043(c) of ERISA has occurred with
        respect to any Pension Plan other than an event for which the notice requirement
        has been waived by the PBGC.  None of the Credit Parties has engaged
        in a prohibited transaction with respect to any Pension Plan, other than
        a
        prohibited transaction for which an exemption is available and has been
        obtained, which could subject such Credit Parties to a material tax or penalty
        imposed by Section 4975 of the Internal Revenue Code or Section 502(i) of
        ERISA.  Each Pension Plan is being maintained and funded in accordance
        with its terms and is in material compliance with the requirements of the
        Internal Revenue Code and ERISA.  No Credit Party has had a complete
        or partial withdrawal from any Multiemployer Plan that has resulted or could
        reasonably be expected to have resulted in any Withdrawal Liability and,
        except
        as notified to Agent in writing following the Effective Date, no such
        Multiemployer Plan is in reorganization (within the meaning of Section 4241
        of
        ERISA) or insolvent (within the meaning of Section 4245 of ERISA).

      

      6.14           Conditions
        Affecting Business or Properties.  Neither the respective
        businesses nor the properties of any Credit Party is affected by any fire,
        explosion, accident, strike, lockout or other dispute, drought, storm, hail,
        earthquake, embargo, Act of God, or other casualty (except to the extent
        such
        event is covered by insurance sufficient to ensure that upon application
        of the
        proceeds thereof, no Material Adverse Effect could reasonably be expected
        to
        occur) which could reasonably be expected to have a Material Adverse
        Effect.

      

      6.15           Environmental
        and Safety Matters.  Except as set forth in Schedules 6.9,
        6.10 and 6.15:

      

      
        	
                 

              	
                (a)

              	
                all
                  facilities and property owned or leased by the Credit Parties are
                  in
                  compliance with all Hazardous Material Laws in all material
                  respects;

              

      

      

      
        	
                 

              	
                (b)

              	
                to
                  the best knowledge of Borrowers, there have been no unresolved
                  and
                  outstanding past, and there are no pending or
                  threatened:

              

      

      

      
        	
                 

              	
                (i)

              	
                claims,
                  complaints, notices or requests for information received by any
                  Credit
                  Party with respect to any alleged violation of any Hazardous Material
                  Law
                  which, if adversely determined, could reasonably be expected to
                  have a
                  Material Adverse Effect, or

              

      

      
        
          
          

        

        
          53

          
            

          

        

        
          
          

        

      

      
        	
                 

              	
                (ii)

              	
                written
                  complaints, notices or inquiries to any Credit Party regarding
                  potential
                  liability of any Credit Parties under any Hazardous Material Law
                  which, if
                  adversely determined, could reasonably be expected to have a Material
                  Adverse Effect; and

              

      

      

      
        	
                 

              	
                (c)

              	
                to
                  the best knowledge of Borrowers, no conditions exist at, on or
                  under any
                  property now or previously owned or leased by any Credit Party
                  which, with
                  the passage of time, or the giving of notice or both, are reasonably
                  likely to give rise to liability under any Hazardous Material Law
                  which
                  solely or together with any other such conditions could reasonably
                  be
                  expected to have a Material Adverse
                  Effect.

              

      

      

      6.16           Subsidiaries.  Except
        as disclosed on Schedule 6.16 hereto as of the Effective Date, and thereafter,
        except as disclosed to the Agent in writing from time to time, no Credit
        Party
        has any Subsidiaries.

      

      6.17           Intentionally
        Omitted.

      

      6.18           Intentionally
        Omitted.

      

      6.19           Franchises,
        Patents, Copyrights, Tradenames, etc.  The Credit Parties
        possess all franchises, patents, copyrights, trademarks, trade names, licenses
        and permits, and rights in respect of the foregoing, adequate for the conduct
        of
        their business substantially as now conducted without known conflict with
        any
        rights of others except where the failure to possess such rights could not
        reasonably be expected to have a Material Adverse Effect.  Schedule
        6.19 contains a true and accurate list of all trade names and any and all
        other
        names used by any Credit Party during the five-year period ending as of the
        Effective Date.

      

      6.20           Capital
        Structure.  Schedule 6.20 attached hereto sets forth all issued
        and outstanding Equity Interests of each Credit Party, including the number
        of
        authorized, issued and outstanding Equity Interests of each Credit Party,
        the
        par value of such Equity Interests and, other than for Sterling, the holders
        of
        such Equity Interests, all on and as of the Effective Date. All issued and
        outstanding Equity Interests of each Credit Party are duly authorized and
        validly issued, fully paid, nonassessable, and, except for the Equity Interests
        of Sterling, free and clear of all Liens (except for the benefit of Agent)
        and
        such Equity Interests were issued in compliance with all applicable state,
        federal and foreign laws concerning the issuance of
        securities.  Except as disclosed on Schedule 6.20, there are no
        preemptive or other outstanding rights, options, warrants, conversion rights
        or
        similar agreements or understandings for the purchase or acquisition from
        any
        Credit Party, of any Equity Interests of any Credit Party.

      

      6.21           Accuracy
        of Information.  (a)  The audited financial
        statements for the Fiscal Year ended December 31, 2006, furnished to Agent
        and
        the Lenders prior to the Effective Date fairly present in all material respects
        the financial condition of Sterling and its Subsidiaries covered thereby
        and the
        results of their operations for the periods covered thereby, and have been
        prepared in accordance with GAAP. The projections and the other pro forma
        financial information delivered to the Agent prior to the Effective Date
        are
        based upon good faith estimates and assumptions believed by management of
        the
        Borrowers to be accurate and reasonable at the time made, it being recognized
        by
        the Lenders that such financial information as it relates to future events
        is
        not to be viewed as fact and that actual results during the period or periods
        covered by such financial information may differ from the projected results
        set
        forth therein.

      
        
          
          

        

        
          54

          
            

          

        

        
          
          

        

      

      (b)           From
        June 30, 2007 through the Effective Date, there has been no material adverse
        change in the business, operations, condition, property or prospects (financial
        or otherwise) of the Credit Parties, taken as a whole.

      

      (c)           To
        the best knowledge of the Credit Parties, as of the Effective Date, (i) the
        Credit Parties do not have any material contingent obligations (including
        any
        liability for taxes) not disclosed by or reserved against in the opening
        balance
        sheet to be delivered hereunder and (ii) there are no unrealized or anticipated
        losses from any present commitment of the Credit Parties which contingent
        obligations and losses in the aggregate could reasonably be expected to have
        a
        Material Adverse Effect.

      

      6.22           Solvency.  After
        giving effect to the consummation of the transactions contemplated by this
        Agreement and other Loan Documents and the Acquisition Documents, each Credit
        Party will be solvent, able to pay its indebtedness as it matures and will
        have
        capital sufficient to carry on its businesses and all business in which it
        is
        about to engage. This Agreement is being executed and delivered by the Borrowers
        to Agent and the Lenders in good faith and in exchange for fair, equivalent
        consideration. The Credit Parties do not intend to nor does management of
        the
        Credit Parties believe the Credit Parties will incur debts beyond their ability
        to pay as they mature. No Credit Party contemplates filing a petition in
        bankruptcy or for an arrangement or reorganization under the Bankruptcy Code
        or
        any similar law of any jurisdiction now or hereafter in effect relating to
        any
        Credit Party, nor does any Credit Party have any knowledge of any threatened
        bankruptcy or insolvency proceedings against a Credit Party.

      

      6.23           Employee
        Matters.  Except as set forth on Schedule 6.23, there are
        no strikes, slowdowns, work stoppages, unfair labor practice complaints,
        grievances, arbitration proceedings or controversies pending or, to the best
        knowledge of the Borrowers, threatened against any Credit Party by any employees
        of any Credit Party, other than non-material employee grievances or
        controversies arising in the ordinary course of business. Set forth on Schedule
        6.23 are all union contracts or agreements to which any Credit Party is party
        as
        of the Effective Date and the related expiration dates of each such
        contract.

      

      6.24           No
        Misrepresentation.  Neither this Agreement nor any other
        Loan Document, certificate, information or report furnished or to be furnished
        by or on behalf of a Credit Party to Agent or any Lender in connection with
        any
        of the transactions contemplated hereby or thereby, contains a misstatement
        of
        material fact, or omits to state a material fact required to be stated in
        order
        to make the statements contained herein or therein, taken as a whole, not
        misleading in the light of the circumstances under which such statements
        were
        made.  There is no fact, other than information known to the public
        generally, known to any Credit Party after diligent inquiry, that could
        reasonably be expect to have a Material Adverse Effect that has not expressly
        been disclosed to Agent in writing.

      6.25           Corporate
        Documents and Corporate Existence.  As to each Credit
        Party, (a) it is an organization as described on Schedule 1.3 hereto and
        has
        provided the Agent and the Lenders with complete and correct copies of its
        articles of incorporation, by-laws and all other applicable charter and other
        organizational documents, and, if applicable, a good standing certificate
        and
        (b) its correct legal name, business address, type of organization and
        jurisdiction of organization, tax identification number and other relevant
        identification numbers are set forth on Schedule 1.3 hereto.

      

      6.26           Acquisition
        Documents.

      

      
        	
                 

              	
                (a)

              	
                Each
                  Acquisition Document to which any Credit Party is a party has been
                  duly
                  authorized and validly executed, constitutes the valid and binding
                  obligation of such Credit Party and is enforceable against such
                  Credit
                  Party in accordance with its terms except as enforcement thereof
                  may be
                  limited by applicable bankruptcy, reorganization, insolvency, fraudulent
                  conveyance, moratorium or similar laws affecting the enforcement
                  of
                  creditor’s rights, generally and by general principles of equity
                  (regardless of whether enforcement is considered in a proceeding
                  in law or
                  equity).  No Acquisition Document to which any Credit Party is a
                  party has been modified, amended, altered or changed in any manner
                  except
                  in compliance with this Agreement, and there are no unwaived defaults,
                  other than such defaults which, either singly or in the aggregate,
                  could
                  not reasonably be expected to have a Material Adverse Effect, existing
                  under the Acquisition Documents by any Credit Party that is a party
                  thereto, or, to the best of the knowledge of any Credit Party,
                  by any
                  other party thereto;

              

      

      

      
        	
                 

              	
                (b)

              	
                The
                  Credit Parties will keep and perform or cause to be kept and performed
                  all
                  of their respective material obligations under the Acquisition
                  Documents;

              

      

      

      
        	
                 

              	
                (c)

              	
                No
                  Credit Party shall have granted a collateral assignment of, or
                  a security
                  interest over the Acquisition Documents (other than in favor of
                  Agent for
                  the benefit of the Lenders) and, no Credit Party shall have sold,
                  transferred or assigned any Acquisition Document to any Person
                  (other than
                  to or in favor of Agent) without the consent of the Agent;
                  and

              

      

      

      
        	
              	
                (d)

              	
                Upon
                  the consummation of the Acquisition, the Borrowers and Sellers
                  shall have
                  obtained all material third party consents reasonably deemed necessary
                  by
                  Agent or otherwise required in connection with the Acquisition
                  and shall
                  have delivered copies to Agent of all additional assignment or
                  assumption
                  agreements entered into in connection therewith, except to the
                  extent
                  waived or extended pursuant to the terms hereof and
                  thereof.

      Each
        Borrower covenants and agrees, so long as any Lender has any commitment to
        extend credit hereunder, or any of the Indebtedness remains outstanding and
        unpaid, that it will, and, as applicable, it will cause each of its Subsidiaries
        to:

                  any other
                  Loan Document), invalidated, revoked or set aside or in any way
                  cease to
                  give or provide to the Lenders and the Agent the benefits purported
                  to be
                  created thereby, or any Loan Document purporting to grant a Lien
                  to secure
                  any Indebtedness shall, at any time after the delivery of such
                  Loan
                  Document, fail to create a valid and enforceable Lien on any Collateral
                  purported to be covered thereby or such Lien shall fail to cease
                  to be a
                  perfected Lien with the priority required in the relevant Loan
                  Document.

              

      

      

      9.2     
              Exercise of
        Remedies.  If an Event of Default has occurred and is
        continuing hereunder: (a) the Agent may, and shall, upon being directed to
        do so
        by the Majority Revolving Credit Lenders, declare the Revolving Credit Aggregate
        Commitment terminated; (b) the Agent may, and shall, upon being directed
        to do
        so by the Majority Lenders, upon notice to the Borrower Representative, declare
        the entire unpaid principal Indebtedness, including the Notes, immediately
        due
        and payable, without presentment, notice (other than as set forth in this
        Section) or demand, all of which are hereby expressly waived by the Borrowers;
        (c) upon the occurrence of any Event of Default specified in Section 9.1(i)
        and
        notwithstanding the lack of any declaration by Agent under preceding clauses
        (a)
        or (b), the entire unpaid principal Indebtedness shall become automatically
        and
        immediately due and payable, and the Revolving Credit Aggregate Commitment
        shall
        be automatically and immediately terminated; (d) the Agent shall, upon being
        directed to do so by the Majority Revolving Credit Lenders, demand immediate
        delivery of cash collateral, and each Borrower agrees to deliver such cash
        collateral upon demand, in an amount equal to 105% of the maximum amount
        that
        may be available to be drawn at any time prior to the stated expiry of all
        outstanding Letters of Credit, for deposit into an account controlled by
        the
        Agent; (e) the Agent may, and shall, upon being directed to do so by the
        Majority Lenders, notify Borrowers or any Credit Party that interest shall
        be
        payable on demand on all Indebtedness (other than Revolving Credit Advances
        and
        Swing Line Advances with respect to which Sections 2.6 hereof shall govern)
        owing from time to time to the Agent or any Lender, at a per annum rate equal
        to
        the then applicable Prime-based Rate plus two percent (2%); and (f) the Agent
        may, and shall, upon being directed to do so by the Majority Lenders or the
        Lenders, as applicable (subject to the terms hereof), exercise any remedy
        permitted by this Agreement, the other Loan Documents or law.

      

      9.3        
           Rights Cumulative.  No delay or
        failure of Agent and/or Lenders in exercising any right, power or privilege
        hereunder shall affect such right, power or privilege, nor shall any single
        or
        partial exercise thereof preclude any further exercise thereof, or the exercise
        of any other power, right or privilege. The rights of Agent and Lenders under
        this Agreement are cumulative and not exclusive of any right or remedies
        which
        Lenders would otherwise have.

      9.4        
           Waiver by Borrowers of Certain
        Laws.  To the extent permitted by applicable law, each
        Borrower hereby agrees to waive, and does hereby absolutely and irrevocably
        waive and relinquish the benefit and advantage of any valuation, stay,
        appraisement, extension or redemption laws now existing or which may hereafter
        exist, which, but for this provision, might be applicable to any sale made
        under
        the judgment, order or decree of any court, on any claim for interest on
        the
        Notes, or any security interest or mortgage contemplated by or granted under
        or
        in connection with this Agreement. These waivers have been voluntarily given,
        with full knowledge of the consequences thereof.

      

      9.5         
          Waiver of Defaults.  No Event of Default shall be
        waived by the Lenders except in a writing signed by an officer of the Agent
        in
        accordance with Section 13.10 hereof. No single or partial exercise of any
        right, power or privilege hereunder, nor any delay in the exercise thereof,
        shall preclude other or further exercise of their rights by Agent or the
        Lenders. No waiver of any Event of Default shall extend to any other or further
        Event of Default. No forbearance on the part of the Agent or the Lenders
        in
        enforcing any of their rights shall constitute a waiver of any of their rights.
        Each Borrower expressly agrees that this Section may not be waived or modified
        by the Lenders or Agent by course of performance, estoppel or
        otherwise.

      

      9.6          
         Set Off.  Upon the occurrence and during the
        continuance of any Event of Default, each Lender may at any time and from
        time
        to time, without notice to Borrowers but subject to the provisions of Section
        10.3 hereof (any requirement for such notice being expressly waived by
        Borrowers), setoff and apply against any and all of the obligations of Borrowers
        now or hereafter existing under this Agreement, whether owing to such Lender,
        any Affiliate of such Lender or any other Lender or the Agent, any and all
        deposits (general or special, time or demand, provisional or final) at any
        time
        held and other indebtedness at any time owing by such Lender to or for the
        credit or the account of Borrowers and any property of Borrowers from time
        to
        time in possession of such Lender, irrespective of whether or not such deposits
        held or indebtedness owing by such Lender may be contingent and unmatured
        and
        regardless of whether any Collateral then held by Agent or any Lender is
        adequate to cover the Indebtedness. Promptly following any such setoff, such
        Lender shall give written notice to Agent and Borrowers of the occurrence
        thereof. Each Borrower hereby grants to the Lenders and the Agent a lien
        on and
        security interest in all such deposits, indebtedness and property as collateral
        security for the payment and performance of all of the obligations of Borrowers
        under this Agreement. The rights of each Lender under this Section 9.6 are
        in
        addition to the other rights and remedies (including, without limitation,
        other
        rights of setoff) which such Lender may have.

      10.1           Payment
        Procedure.

      

      (a)           All
        payments to be made by Borrowers shall be made without condition or deduction
        for any counterclaim, defense, recoupment or setoff.  Except as
        otherwise provided herein, all payments made by the Borrowers of principal,
        interest or fees hereunder shall be made without setoff or counterclaim on
        the
        date specified for payment under this Agreement and must be received by Agent
        not later than 1:00 p.m. (Detroit time) on the date such payment is required
        or
        intended to be made in Dollars in immediately available funds to Agent at
        Agent’s office located at One Detroit Center, Detroit, Michigan 48226-3289 for
        the ratable benefit of the Revolving Credit Lenders in the case of payments
        in
        respect of the Revolving Credit and any Letter of Credit Obligations. Any
        payment received by the Agent after 1:00 p.m. (Detroit time) shall be deemed
        received on the next succeeding Business Day and any applicable interest
        or fee
        shall continue to accrue.  Upon receipt of each such payment, the
        Agent shall make prompt payment to each applicable Lender, or, in respect
        of
        Eurodollar-based Advances, such Lender’s Eurodollar Lending Office, in like
        funds and currencies, of all amounts received by it for the account of such
        Lender.

      
        
          
          

        

        
          76

          
            

          

        

        
          
          

        

      

      (b)           Unless
        the Agent shall have been notified in writing by Borrowers at least two (2)
        Business Days prior to the date on which any payment to be made by Borrowers
        is
        due that no Borrower intends to remit such payment, the Agent may, in its
        sole
        discretion and without obligation to do so, assume that Borrowers have remitted
        such payment when so due and the Agent may, in reliance upon such assumption,
        make available to each Revolving Credit Lender, on such payment date an amount
        equal to such Lender’s share of such assumed payment. If Borrowers have not in
        fact remitted such payment to the Agent, each Lender shall forthwith on demand
        repay to the Agent the amount of such assumed payment made available or
        transferred to such Lender, together with the interest thereon, in respect
        of
        each day from and including the date such amount was made available by the
        Agent
        to such Lender to the date such amount is repaid to the Agent at a rate per
        annum equal to the Federal Funds Effective Rate for the first two (2) Business
        Days that such amount remains unpaid, and thereafter at a rate of interest
        then
        applicable to such Revolving Credit Advances.

      

      (c)           Subject
        to the definition of “Interest Period” in Section 1 of this Agreement, whenever
        any payment to be made hereunder shall otherwise be due on a day which is
        not a
        Business Day, such payment shall be made on the next succeeding Business
        Day and
        such extension of time shall be included in computing interest, if any, in
        connection with such payment.

      

      (d)           All
        payments to be made by Borrowers under this Agreement or any of the Notes
        (including without limitation payments under the Swing Line and/or Swing
        Line
        Note) shall be made without setoff or counterclaim, as aforesaid, and, subject
        to full compliance by each Lender (and each assignee and participant pursuant
        to
        Section 13.8) with Section 13.13, without deduction for or on account of
        any
        present or future withholding or other taxes of any nature imposed by any
        governmental authority or of any political subdivision thereof or any federation
        or organization of which such governmental authority may at the time of payment
        be a member (other than any taxes on the overall income, net income, net
        profits
        or net receipts or similar taxes (or any franchise taxes imposed in lieu
        of such
        taxes) on the Agent or any Lender (or any branch maintained by Agent or a
        Lender) as a result of a present or former connection between the Agent or
        such
        Lender and the governmental authority, political subdivision, federation
        or
        organization imposing such taxes), unless Borrowers are compelled by law
        to make
        payment subject to such tax. In such event, Borrowers shall:

      

      
        	
                 

              	
                (i)

              	
                pay
                  to the Agent for Agent’s own account and/or, as the case may be, for the
                  account of the Lenders such additional amounts as may be necessary
                  to
                  ensure that the Agent and/or such Lender or Lenders (including
                  the Swing
                  Line Lender) receive a net amount equal to the full amount which
                  would
                  have been receivable had payment not been made subject to such
                  tax;
                  and

                (ii)

              	
                remit
                  such tax to the relevant taxing authorities according to applicable
                  law,
                  and send to the Agent or the applicable Lender or Lenders (including
                  the
                  Swing Line Lender), as the case may be, such certificates or certified
                  copy receipts as the Agent or such Lender or Lenders shall reasonably
                  require as proof of the payment by Borrowers of any such taxes
                  payable by
                  Borrowers.

              

      

      

      As
        used
        herein, the terms “tax”, “taxes” and “taxation” include all taxes, levies,
        imposts, duties, fees, deductions and withholdings or similar charges together
        with interest (and any taxes payable upon the amounts paid or payable pursuant
        to this Section 10.1) thereon. Each Borrower shall be reimbursed by the
        applicable Lender for any payment made by such Borrower under this Section
        10.1
        if the applicable Lender is not in compliance with its obligations under
        Section
        13.13 at the time of such Borrower’s payment.

      

      10.2           Application
        of Proceeds of Collateral.  Notwithstanding anything to the
        contrary in this Agreement, in the case of any Event of Default under Section
        9.1(i), immediately following the occurrence thereof, and in the case of
        any
        other Event of Default, upon the termination of the Revolving Credit Aggregate
        Commitment, the acceleration of any Indebtedness arising under this Agreement
        and/or the exercise of any other remedy in each case by the requisite Lenders
        under Section 9.2 hereof, the Agent shall apply the proceeds of any Collateral,
        together with any offsets, voluntary payments by any Credit Party or others
        and
        any other sums received or collected in respect of the Indebtedness first,
        to
        pay all incurred and unpaid fees and expenses of the Agent under the Loan
        Documents and any protective advances made by Agent with respect to the
        Collateral under or pursuant to the terms of any Loan Document, next, to
        pay any
        fees and expenses owed to the Issuing Lender hereunder, next, to the
        Indebtedness under the Revolving Credit (including the Swing Line and any
        Reimbursement Obligations), any obligations owing by any Credit party under
        any
        Hedging Agreements or in connection with any Lender Products on a pro rata
        basis, next, to any other Indebtedness on a pro rata basis, and then, if
        there
        is any excess, to the Credit Parties or as otherwise required under applicable
        law, as the case may be.

      

      10.3           Pro-rata
        Recovery.  If any Lender shall obtain any payment or other
        recovery (whether voluntary, involuntary, by application of setoff or otherwise)
        on account of principal of, or interest on, any of the Advances made by it,
        or
        the participations in Letter of Credit Obligations or Swing Line Advances
        held
        by it in excess of its pro rata share of payments then or thereafter obtained
        by
        all Lenders upon principal of and interest on all such Indebtedness, such
        Lender
        shall purchase from the other Lenders such participations in the Revolving
        Credit and/or the Letter of Credit Obligation held by them as shall be necessary
        to cause such purchasing Lender to share the excess payment or other recovery
        ratably in accordance with the applicable Percentages of the Lenders; provided,
        however, that if all or any portion of the excess payment or other recovery
        is
        thereafter recovered from such purchasing holder, the purchase shall be
        rescinded and the purchase price restored to the extent of such recovery,
        but
        without interest.

      11.1           Reimbursement
        of Prepayment Costs.  If (i) Borrowers make any payment of
        principal with respect to any Eurodollar-based Advance or Quoted Rate Advance
        on
        any day other than the last day of the Interest Period applicable thereto
        (whether voluntarily, pursuant to any mandatory provisions hereof, by
        acceleration, or otherwise); (ii) Borrowers convert or refund (or attempt
        to
        convert or refund) any such Advance on any day other than the last day of
        the
        Interest Period applicable thereto (except as described in Section 2.5(e));
        (iii) Borrowers fail to borrow, refund or convert any Eurodollar-based Advance
        or Quoted Rate Advance after notice has been given by Borrowers to Agent
        in
        accordance with the terms hereof requesting such Advance; or (iv) or if the
        Borrowers fail to make any payment of principal in respect of a Eurodollar-based
        Advance or Quoted Rate Advance when due, the Borrowers shall jointly and
        severally reimburse Agent for itself and/or on behalf of any Lender, as the
        case
        may be, within ten (10) Business Days of written demand therefor for any
        resulting loss, cost or expense incurred (excluding the loss of any Applicable
        Margin) by Agent and Lenders, as the case may be, as a result thereof,
        including, without limitation, any such loss, cost or expense incurred in
        obtaining, liquidating, employing or redeploying deposits from third parties,
        whether or not Agent and Lenders, as the case may be, shall have funded or
        committed to fund such Advance. The amount payable hereunder by Borrowers
        (jointly and severally) and to Agent for itself and/or on behalf of any Lender,
        as the case may be, shall be deemed to equal an amount equal to the excess,
        if
        any, of (a) the amount of interest which would have accrued on the amount
        so
        prepaid, or not so borrowed, refunded or converted, for the period from the
        date
        of such prepayment or of such failure to borrow, refund or convert, through
        the
        last day of the relevant Interest Period, at the applicable rate of interest
        for
        said Advance(s) provided under this Agreement, over (b) the amount of interest
        (as reasonably determined by Agent and Lenders, as the case may be) which
        would
        have accrued to Agent and Lenders, as the case may be, on such amount by
        placing
        such amount on deposit for a comparable period with leading banks in the
        interbank eurocurrency market. Calculation of any amounts payable to any
        Lender
        under this paragraph shall be made as though such Lender shall have actually
        funded or committed to fund the relevant Advance through the purchase of
        an
        underlying deposit in an amount equal to the amount of such Advance and having
        a
        maturity comparable to the relevant Interest Period; provided, however, that
        any
        Lender may fund any Eurodollar-based Advance or Quoted Rate Advance, as the
        case
        may be, in any manner it deems fit and the foregoing assumptions shall be
        utilized only for the purpose of the calculation of amounts payable under
        this
        paragraph. Upon the written request of Borrower Representative, Agent and
        Lenders shall deliver to Borrower Representative a certificate setting forth
        the
        basis for determining such losses, costs and expenses, which certificate
        shall
        be conclusively presumed correct, absent manifest error.

      

      11.2           Eurodollar
        Lending Office.  For any Eurodollar Advance, if Agent or a
        Lender, as applicable, shall designate a Eurodollar Lending Office which
        maintains books separate from those of the rest of Agent or such Lender,
        Agent
        or such Lender, as the case may be, shall have the option of maintaining
        and
        carrying the relevant Advance on the books of such Eurodollar Lending
        Office.

      

      11.3           Circumstances
        Affecting Eurodollar-based Rate Availability.  If, with respect to
        any Eurodollar-Interest Period, Agent or the Majority Lenders (after
        consultation with Agent) shall determine in good faith that, by reason of
        circumstances affecting the foreign exchange and interbank markets generally,
        deposits in eurodollars in the applicable amounts are not being offered to
        the
        Agent or such Lenders for such Eurodollar-Interest Period, then Agent shall
        forthwith give notice thereof to Borrower Representative. Thereafter, until
        Agent notifies the Borrower Representative that such circumstances no longer
        exist, (i) the obligation of Lenders to make Eurodollar-based Advances, and
        the
        right of Borrowers to convert an Advance to or refund an Advance as a
        Eurodollar-based Advance, as the case may be, shall be suspended, and (ii)
        effective upon the last day of each Eurodollar-Interest Period related to
        any
        existing Eurodollar-based Advance, each such Eurodollar-based Advance shall
        automatically be converted into a Prime-based Advance (without regard to
        satisfaction of any conditions to conversion contained elsewhere
        herein).

      11.4           Laws
        Affecting Eurodollar-based Advance Availability.  If, after
        the date of this Agreement, the adoption or introduction of, or any change
        in,
        any applicable law, rule or regulation or in the interpretation or
        administration thereof by any governmental authority charged with the
        interpretation or administration thereof, or compliance by any of the Lenders
        (or any of their respective Eurodollar Lending Offices) with any request
        or
        directive (whether or not having the force of law) of any such authority,
        shall
        make it unlawful or impossible for any of the Lenders (or any of their
        respective Eurodollar Lending Offices) to honor its obligations hereunder
        to
        make or maintain any Advance with interest at the Eurodollar-based Rate,
        such
        Lender shall forthwith give notice thereof to Borrower Representative and
        to
        Agent. Thereafter, (a) the obligations of the applicable Lenders to make
        Eurodollar-based Advances and the right of Borrowers to convert an Advance
        into
        or refund an Advance as a Eurodollar-based Advance shall be suspended and
        thereafter Borrowers may select as Applicable Interest Rates only those which
        remain available and which are permitted to be selected hereunder, and (b)
        if
        any of the Lenders may not lawfully continue to maintain an Advance to the
        end
        of the then current Eurodollar-Interest Period applicable thereto as a
        Eurodollar-based Advance, the applicable Advance shall immediately be converted
        to a Prime-based Advance and the Prime-based Rate shall be applicable thereto
        for the remainder of such Eurodollar-Interest Period. For purposes of this
        Section, a change in law, rule, regulation, interpretation or administration
        shall include, without limitation, any change made or which becomes effective
        on
        the basis of a law, rule, regulation, interpretation or administration presently
        in force, the effective date of which change is delayed by the terms of such
        law, rule, regulation, interpretation or administration.

      

      11.5           Increased
        Cost of Eurodollar-based Advances.  If, after the date of
        this Agreement, the adoption or introduction of, or any change in, any
        applicable law, rule or regulation or 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 of
        the
        Lenders (or any of their respective Eurodollar Lending Offices) with any
        request
        or directive (whether or not having the force of law) of any such authority,
        central bank or comparable agency:

      

      
        	
                 

              	
                (a)

              	
                shall
                  subject any of the Lenders (or any of their respective Eurodollar
                  Lending
                  Offices) to any tax, duty or other charge with respect to any Advance
                  or
                  shall change the basis of taxation of payments to any of the Lenders
                  (or
                  any of their respective Eurodollar Lending Offices) of the principal
                  of or
                  interest on any Advance or any other amounts due under this Agreement
                  in
                  respect thereof (except for changes in the rate of tax on the overall
                  net
                  income of any of the Lenders or any of their respective Eurodollar
                  Lending
                  Offices); or

              

      

      
        
          
          

        

        
          80

          
            

          

        

        
          
          

        

      

      
        	
                 

              	
                (b)

              	
                shall
                  impose, modify or deem applicable any reserve (including, without
                  limitation, any imposed by the Board of Governors of the Federal
                  Reserve
                  System), special deposit or similar requirement against assets
                  of,
                  deposits with or for the account of, or credit extended by, any
                  of the
                  Lenders (or any of their respective Eurodollar Lending Offices)
                  or shall
                  impose on any of the Lenders (or any of their respective Eurodollar
                  Lending Offices) or the foreign exchange and interbank markets
                  any other
                  condition affecting any Advance;

              

      

      

      and
        the
        result of any of the foregoing matters is to increase the costs to any of
        the
        Lenders of maintaining any part of the Indebtedness hereunder as a
        Eurodollar-based Advance or to reduce the amount of any sum received or
        receivable by any of the Lenders under this Agreement in respect of a
        Eurodollar-based Advance, then such Lender shall promptly notify Agent, and
        Agent shall promptly notify Borrower Representative of such fact and demand
        compensation therefor and, within ten (10) Business Days after such notice,
        Borrowers jointly and severally agree to pay to such Lender or Lenders such
        additional amount or amounts as will compensate such Lender or Lenders for
        such
        increased cost or reduction, provided that each Lender agrees to take any
        reasonable action, to the extent such action could be taken without cost
        or
        administrative or other burden or restriction to such Lender, to mitigate
        or
        eliminate such cost or reduction, within a reasonable time after becoming
        aware
        of the foregoing matters. Agent will promptly notify Borrower Representative
        of
        any event of which it has knowledge which will entitle Lenders to compensation
        pursuant to this Section, or which will cause Borrowers to incur additional
        liability under Section 11.1 hereof, provided that Agent shall incur no
        liability whatsoever to the Lenders or Borrowers in the event it fails to
        do so.
        A certificate of Agent (or such Lender, if applicable) setting forth the
        basis
        for determining such additional amount or amounts necessary to compensate
        such
        Lender or Lenders shall accompany such demand and shall be conclusively presumed
        to be correct absent manifest error.

      

      11.6           Capital
        Adequacy and Other Increased Costs.

      

      
        	
                 

              	
                (a)

              	
                If,
                  after the date of this Agreement, the adoption or introduction
                  of, or any
                  change in any applicable law, treaty, rule or regulation (whether
                  domestic
                  or foreign) now or hereafter in effect and whether or not presently
                  applicable to any Lender or Agent, or any interpretation or administration
                  thereof by any governmental authority charged with the interpretation
                  or
                  administration thereof, or compliance by any Lender or Agent with
                  any
                  guideline, request or directive of any such authority (whether
                  or not
                  having the force of law), including any risk based capital guidelines,
                  affects or would affect the amount of capital required to be maintained
                  by
                  such Lender or Agent (or any corporation controlling such Lender
                  or Agent)
                  and such Lender or Agent, as the case may be, determines that the
                  amount
                  of such capital is increased by or based upon the existence of
                  such
                  Lender’s or Agent’s obligations or Advances hereunder and such increase
                  has the effect of reducing the rate of return on such Lender’s or Agent’s
                  (or such controlling corporation’s) capital as a consequence of such
                  obligations or Advances hereunder to a level below that which such
                  Lender
                  or Agent (or such controlling corporation) could have achieved
                  but for
                  such circumstances (taking into consideration its policies with
                  respect to
                  capital adequacy) by an amount deemed by such Lender or Agent to
                  be
                  material (collectively, “Increased Costs”), then Agent or such Lender
                  shall notify the Borrower Representative, and thereafter Borrowers
                  shall
                  pay, jointly and severally, to such Lender or Agent, as the case
                  may be,
                  within ten (10) Business Days of written demand therefor from such
                  Lender
                  or Agent, additional amounts sufficient to compensate such Lender
                  or Agent
                  (or such controlling corporation) for any increase in the amount
                  of
                  capital and reduced rate of return which such Lender or Agent reasonably
                  determines to be allocable to the existence of such Lender’s or Agent’s
                  obligations or Advances hereunder. A statement setting forth the
                  amount of
                  such compensation, the methodology for the calculation and the
                  calculation
                  thereof which shall also be prepared in good faith and in reasonable
                  detail by such Lender or Agent, as the case may be, shall be submitted
                  by
                  such Lender or by Agent to Borrower Representative, reasonably
                  promptly
                  after becoming aware of any event described in this Section 11.6(a)
                  and
                  shall be conclusively presumed to be correct, absent manifest
                  error.

                (b)

              	
                Notwithstanding
                  the foregoing, however, Borrowers shall not be required to pay
                  any
                  increased costs under Sections 11.5, 11.6 or 3.4(c) for any period
                  ending
                  prior to the date that is 180 days prior to the making of a Lender’s
                  initial request for such additional amounts unless the applicable
                  change
                  in law or other event resulting in such increased costs is effective
                  retroactively to a date more than 180 days prior to the date of
                  such
                  request, in which case a Lender’s request for such additional amounts
                  relating to the period more than 180 days prior to the making of
                  the
                  request must be given not more than 180 days after such Lender
                  becomes
                  aware of the applicable change in law or other event resulting
                  in such
                  increased costs.

              

      

      

      11.7           Right
        of Lenders to Fund through Branches and Affiliates.  Each
        Lender (including without limitation the Swing Line Lender) may, if it so
        elects, fulfill its commitment as to any Advance hereunder by designating
        a
        branch or Affiliate of such Lender to make such Advance; provided that (a)
        such
        Lender shall remain solely responsible for the performances of its obligations
        hereunder and (b) no such designation shall result in any material increased
        costs to Borrowers.

      

      11.8           Margin
        Adjustment.  Adjustments to the Applicable Margins and the
        Applicable Fee Percentages, based on Schedule 1.1, shall be implemented on
        a
        quarterly basis as follows:

      

      
        	
                 

              	
                (a)

              	
                Such
                  adjustments shall be given prospective effect only, effective as
                  to all
                  Advances outstanding hereunder, the Applicable Fee Percentage and
                  the
                  Letter of Credit Fee, upon the date of delivery of the financial
                  statements under Sections 7.1(a) and 7.1(b) hereunder and the Covenant
                  Compliance Report under Section 7.2(a) hereof, in each case establishing
                  applicability of the appropriate adjustment and in each case with
                  no
                  retroactivity or claw-back. In the event Borrowers shall fail timely
                  to
                  deliver such financial statements or the Covenant Compliance Report
                  and
                  such failure continues for three (3) days, then (but without affecting
                  the
                  Event of Default resulting therefrom) from the date delivery of
                  such
                  financial statements and report was required until such financial
                  statements and report are delivered, the Applicable Margins and
                  Applicable
                  Fee Percentages shall be at the highest level on the Pricing Matrix
                  attached to this Agreement as Schedule
                  1.1.

                From
                  the Effective Date until the required date of delivery (or, if
                  earlier,
                  delivery) of the financial statements under Section 7.1(a) or 7.1(b)
                  hereof, as applicable, and the Covenant Compliance Report under
                  Section
                  7.2(a) hereof, for the fiscal quarter ending December 31, 2007,
                  the
                  Applicable Margins and Applicable Fee Percentages shall be those
                  set forth
                  under the Level II column of the pricing matrix attached to this
                  Agreement
                  as Schedule 1.1. Thereafter, Applicable Margins and Applicable
                  Fee
                  Percentages shall be based upon the quarterly financial statements
                  and
                  Covenant Compliance Reports, subject to recalculation as provided
                  in
                  Section 11.8(a) above.

              

      

      

      
        	
                 

              	
                (c)

              	
                Notwithstanding
                  the foregoing, however, if, prior to the payment and discharge
                  in full (in
                  cash) of the Indebtedness and the termination of any and all commitments
                  hereunder, as a result of any restatement of or adjustment to the
                  financial statements of Sterling and any of its Subsidiaries (relating
                  to
                  the current or any prior fiscal period) or for any other miscalculation
                  or
                  error, Agent determines that the Applicable Margin and/or the Applicable
                  Fee Percentages as calculated by Borrowers as of any applicable
                  date of
                  determination were inaccurate in any respect and a proper calculation
                  thereof would have resulted in different pricing for any fiscal
                  period,
                  then (x) if the proper calculation thereof would have resulted
                  in higher
                  pricing for any such period, Borrowers shall automatically and
                  retroactively be jointly and severally obligated to pay to Agent,
                  promptly
                  upon demand by Agent or the Majority Lenders, an amount equal to
                  the
                  excess of the amount of interest and fees that should have been
                  paid for
                  such period over the amount of interest and fees actually paid
                  for such
                  period and, if the current fiscal period is affected thereby, the
                  Applicable Margin and/or the Applicable Fee Percentages for the
                  current
                  period shall be adjusted based on such recalculation; and (y) if
                  the
                  proper calculation thereof would have resulted in lower pricing
                  for such
                  period, Agent and Lenders shall have no obligation to recalculate
                  such
                  interest or fees or to repay any interest or fees to the
                  Borrowers.

              

      

      

      
        	
                12.

              	
                AGENT.

              

      

      

      12.1           Appointment
        of Agent.  Each Lender and the holder of each Note (if
        issued) irrevocably appoints and authorizes the Agent to act on behalf of
        such
        Lender or holder under this Agreement and the other Loan Documents and to
        exercise such powers hereunder and thereunder as are specifically delegated
        to
        Agent by the terms hereof and thereof, together with such powers as may be
        reasonably incidental thereto, including without limitation the power to
        execute
        or authorize the execution of financing or similar statements or notices,
        and
        other documents. In performing its functions and duties under this Agreement,
        the Agent shall act solely as agent of the Lenders and does not assume and
        shall
        not be deemed to have assumed any obligation towards or relationship of agency
        or trust with or for any Credit Party.

      12.2           Deposit
        Account with Agent.  Each Borrower authorizes Agent, in
        Agent’s sole discretion, upon notice to the Borrower Representative to charge
        its general deposit account(s), if any, maintained with the Agent for the
        amount
        of any principal, interest, or other amounts or costs due under this Agreement
        when the same become due and payable under the terms of this Agreement or
        the
        Notes.

      

      12.3           Scope
        of Agent’s Duties.  The Agent shall have no duties or
        responsibilities except those expressly set forth herein, and shall not,
        by
        reason of this Agreement or otherwise, have a fiduciary relationship with
        any
        Lender (and no implied covenants or other obligations shall be read into
        this
        Agreement against the Agent). None of Agent, its Affiliates nor any of their
        respective directors, officers, employees or agents shall be liable to any
        Lender for any action taken or omitted to be taken by it or them under this
        Agreement or any document executed pursuant hereto, or in connection herewith
        or
        therewith with the consent or at the request of the Majority Lenders (or
        all of
        the Lenders for those acts requiring consent of all of the Lenders) (except
        for
        its or their own willful misconduct or gross negligence), nor be responsible
        for
        or have any duties to ascertain, inquire into or verify (a) any recitals
        or
        warranties made by the Credit Parties or any Affiliate of the Credit Parties,
        or
        any officer thereof contained herein or therein, (b) the effectiveness,
        enforceability, validity or due execution of this Agreement or any document
        executed pursuant hereto or any security thereunder, (c) the performance
        by the
        Credit Parties of their respective obligations hereunder or thereunder, or
        (d)
        the satisfaction of any condition hereunder or thereunder, including without
        limitation in connection with the making of any Advance or the issuance of
        any
        Letter of Credit. Agent and its Affiliates shall be entitled to rely upon
        any
        certificate, notice, document or other communication (including any cable,
        telegraph, telex, facsimile transmission or oral communication) believed
        by it
        to be genuine and correct and to have been sent or given by or on behalf
        of a
        proper person. Agent may treat the payee of any Note as the holder thereof.
        Agent may employ agents and may consult with legal counsel, independent public
        accountants and other experts selected by it and shall not be liable to the
        Lenders (except as to money or property received by them or their authorized
        agents), for the negligence or misconduct of any such agent selected by it
        with
        reasonable care or for any action taken or omitted to be taken by it in good
        faith in accordance with the advice of such counsel, accountants or
        experts.

      12.4           Successor
        Agent.  Agent may resign as such at any time upon at least
        thirty (30) days prior notice to Borrower Representative and each of the
        Lenders. If Agent at any time shall resign or if the office of Agent shall
        become vacant for any other reason, Majority Lenders shall, by written
        instrument,  appoint successor agent(s) (“Successor Agent”)
        satisfactory to such Majority Lenders and, so long as no Default or Event
        of
        Default has occurred and is continuing, to Borrower Representative (which
        approval shall not be unreasonably withheld or delayed); provided, however
        that
        any such successor Agent shall be a bank or a trust company or other financial
        institution which maintains an office in the United States, or a commercial
        bank
        organized under the laws of the United States or any state thereof, or any
        Affiliate of such bank or trust company or other financial institution which
        is
        engaged in the banking business, and shall have a combined capital and surplus
        of at least $500,000,000. Such Successor Agent shall thereupon become the
        Agent
        hereunder, as applicable, and Agent shall deliver or cause to be delivered
        to
        any successor agent such documents of transfer and assignment as such Successor
        Agent may reasonably request. If a Successor Agent is not so appointed or
        does
        not accept such appointment before the resigning Agent’s resignation becomes
        effective, the resigning Agent may appoint a temporary successor to act until
        such appointment by the Majority Lenders and, if applicable, Borrower
        Representative, is made and accepted, or if no such temporary successor is
        appointed as provided above by the resigning Agent, the Majority Lenders
        shall
        thereafter perform all of the duties of the resigning Agent hereunder until
        such
        appointment by the Majority Lenders and, if applicable, Borrower Representative,
        is made and accepted. Such Successor Agent shall succeed to all of the rights
        and obligations of the resigning Agent as if originally named. The resigning
        Agent shall duly assign, transfer and deliver to such Successor Agent all
        moneys
        at the time held by the resigning Agent hereunder after deducting therefrom
        its
        expenses for which it is entitled to be reimbursed hereunder. Upon such
        succession of any such Successor Agent, the resigning Agent shall be discharged
        from its duties and obligations, in its capacity as Agent hereunder, except
        for
        its gross negligence or willful misconduct arising prior to its resignation
        hereunder, and the provisions of this Article 12 shall continue in effect
        for
        the benefit of the resigning Agent in respect of any actions taken or omitted
        to
        be taken by it while it was acting as Agent.

      

      12.5           Credit
        Decisions.  Each Lender acknowledges that it has, independently of
        Agent and each other Lender and based on the financial statements of Borrowers
        and such other documents, information and investigations as it has deemed
        appropriate, made its own credit decision to extend credit hereunder from
        time
        to time. Each Lender also acknowledges that it will, independently of Agent
        and
        each other Lender and based on such other documents, information and
        investigations as it shall deem appropriate at any time, continue to make
        its
        own credit decisions as to exercising or not exercising from time to time
        any
        rights and privileges available to it under this Agreement, any Loan Document
        or
        any other document executed pursuant hereto.

      

      12.6           Authority
        of Agent to Enforce This Agreement.  Each Lender, subject
        to the terms and conditions of this Agreement, grants the Agent full power
        and
        authority as attorney-in-fact to institute and maintain actions, suits or
        proceedings for the collection and enforcement of any Indebtedness outstanding
        under this Agreement or any other Loan Document and to file such proofs of
        debt
        or other documents as may be necessary to have the claims of the Lenders
        allowed
        in any proceeding relative to any Credit Party, or their respective creditors
        or
        affecting their respective properties, and to take such other actions which
        Agent considers to be necessary or desirable for the protection, collection
        and
        enforcement of the Notes, this Agreement or the other Loan
        Documents.

      12.7           Indemnification
        of Agent.  The Lenders agree (which agreement shall survive
        the expiration or termination of this Agreement) to indemnify the Agent and
        its
        Affiliates (to the extent not reimbursed by Borrowers, but without limiting
        any
        obligation of Borrowers to make such reimbursement), ratably according to
        their
        respective Percentages, from and against any and all claims, damages, losses,
        liabilities, costs or expenses of any kind or nature whatsoever (including,
        without limitation, reasonable fees and expenses of house and outside counsel)
        which may be imposed on, incurred by, or asserted against the Agent and its
        Affiliates in any way relating to or arising out of this Agreement, any of
        the
        other Loan Documents or the transactions contemplated hereby or any action
        taken
        or omitted by the Agent and its Affiliates under this Agreement or any of
        the
        Loan Documents; provided, however, that no Lender shall be liable for any
        portion of such claims, damages, losses, liabilities, costs or expenses
        resulting from the Agent’s or its Affiliate’s gross negligence or willful
        misconduct. Without limitation of the foregoing, each Lender agrees to reimburse
        the Agent and its Affiliates promptly upon demand for its ratable share of
        any
        reasonable out-of-pocket expenses (including, without limitation, reasonable
        fees and expenses of house and outside counsel) incurred by the Agent and
        its
        Affiliates in connection with the preparation, execution, delivery,
        administration, modification, amendment or enforcement (whether through
        negotiations, legal proceedings or otherwise) of, or legal advice in respect
        of
        rights or responsibilities under, this Agreement or any of the other Loan
        Documents, to the extent that the Agent and its Affiliates are not reimbursed
        for such expenses by Borrowers, but without limiting the obligation of Borrowers
        to make such reimbursement. Each Lender agrees to reimburse the Agent and
        its
        Affiliates promptly upon demand for its ratable share of any amounts owing
        to
        the Agent and its Affiliates by the Lenders pursuant to this Section, provided
        that, if the Agent or its Affiliates are subsequently reimbursed by Borrowers
        for such amounts, they shall refund to the Lenders on a pro rata basis the
        amount of any excess reimbursement. If the indemnity furnished to the Agent
        and
        its Affiliates under this Section shall become impaired as determined in
        the
        Agent’s reasonable judgment or Agent shall elect in its sole discretion to have
        such indemnity confirmed by the Lenders (as to specific matters or otherwise),
        Agent shall give notice thereof to each Lender and, until such additional
        indemnity is provided or such existing indemnity is confirmed, the Agent
        may
        cease, or not commence, to take any action. Any amounts paid by the Lenders
        hereunder to the Agent or its Affiliates shall be deemed to constitute part
        of
        the Indebtedness hereunder.

      

      12.8           Knowledge
        of Default.  It is expressly understood and agreed that the
        Agent shall be entitled to assume that no Default or Event of Default has
        occurred and is continuing, unless the officers of the Agent immediately
        responsible for matters concerning this Agreement shall have received a written
        notice from a Lender or a Borrower specifying such Default or Event of Default
        and stating that such notice is a “notice of default”. Upon receiving such a
        notice, the Agent shall promptly notify each Lender of such Default or Event
        of
        Default and provide each Lender with a copy of such notice and shall endeavor
        to
        provide such notice to the Lenders within three (3) Business Days (but without
        any liability whatsoever in the event of its failure to do so).

      

      12.9           Agent’s
        Authorization; Action by Lenders.  Except as otherwise
        expressly provided herein, whenever the Agent is authorized and empowered
        hereunder on behalf of the Lenders to give any approval or consent, or to
        make
        any request, or to take any other action on behalf of the Lenders (including
        without limitation the exercise of any right or remedy hereunder or under
        the
        other Loan Documents), the Agent shall be required to give such approval
        or
        consent, or to make such request or to take such other action only when so
        requested in writing by the Majority Lenders or the Lenders, as applicable
        hereunder. Action that may be taken by the Majority Lenders, any other specified
        Percentage of the Lenders or all of the Lenders, as the case may be (as provided
        for hereunder) may be taken (i) pursuant to a vote of the requisite percentages
        of the Lenders as required hereunder at a meeting (which may be held by
        telephone conference call), provided that Agent exercises good faith, diligent
        efforts to give all of the Lenders reasonable advance notice of the meeting,
        or
        (ii) pursuant to the written consent of the requisite percentages of the
        Lenders
        as required hereunder, provided that all of the Lenders are given reasonable
        advance notice of the requests for such consent.

      12.10        Enforcement
        Actions by the Agent.  Except as otherwise expressly
        provided under this Agreement or in any of the other Loan Documents and subject
        to the terms hereof, Agent will take such action, assert such rights and
        pursue
        such remedies under this Agreement and the other Loan Documents as the Majority
        Lenders or all of the Lenders, as the case may be (as provided for hereunder),
        shall direct; provided, however, that the Agent shall not be required to
        act or
        omit to act if, in the reasonable judgment of the Agent, such action or omission
        may expose the Agent to personal liability for which Agent has not been
        satisfactorily indemnified hereunder or is contrary to this Agreement, any
        of
        the Loan Documents or applicable law. Except as expressly provided above
        or
        elsewhere in this Agreement or the other Loan Documents, no Lender (other
        than
        the Agent, acting in its capacity as agent) shall be entitled to take any
        enforcement action of any kind under this Agreement or any of the other Loan
        Documents.

      

      12.11        Collateral
        Matters.

      

      (a)           The
        Agent is authorized on behalf of all the Lenders, without the necessity of
        any
        notice to or further consent from the Lenders, from time to time to take
        any
        action with respect to any Collateral or the Collateral Documents which may
        be
        necessary to perfect and maintain a perfected security interest in and Liens
        upon the Collateral granted pursuant to the Loan Documents.

      

      (b)           The
        Lenders irrevocably authorize the Agent, in its reasonable discretion, to
        the
        full extent set forth in the post-amble to Section 13.10 hereof, (1) to release
        or terminate any Lien granted to or held by the Agent upon any Collateral
        (a)
        upon termination of the Revolving Credit Aggregate Commitment and payment
        in
        full of all Indebtedness payable under this Agreement and under any other
        Loan
        Document; (b) constituting property (including, without limitation, Equity
        Interests in any Person) sold or to be sold or disposed of as part of or
        in
        connection with any disposition (whether by sale, by merger or by any other
        form
        of transaction and including the property of any Subsidiary that is disposed
        of
        as permitted hereby) permitted in accordance with the terms of this Agreement;
        (c) constituting property in which a Credit Party owned no interest at the
        time
        the Lien was granted or at any time thereafter; or (d) if approved, authorized
        or ratified in writing by the Majority Lenders, or all the Lenders, as the
        case
        may be, as provided in Section 13.10; (2) to subordinate the Lien granted
        to or
        held by Agent on any Collateral to any other holder of a Lien on such Collateral
        which is permitted by Section 8.2(b) hereof; and (3) if all of the Equity
        Interests held by the Credit Parties in any Person are sold or otherwise
        transferred to any transferee other than a Borrower or a Subsidiary of a
        Borrower as part of or in connection with any disposition (whether by sale,
        by
        merger or by any other form of transaction) permitted in accordance with
        the
        terms of this Agreement, to release such Person from all of its obligations
        under the Loan Documents (including, without limitation, under any Guaranty).
        Upon request by the Agent at any time, the Lenders will confirm in writing
        the
        Agent’s authority to release particular types or items of Collateral pursuant to
        this Section 12.11(b).

        Affiliates, successors and assigns shall each have the same rights and powers
        hereunder as any other Lender and may exercise or refrain from exercising
        the
        same as though such Lender were not the Agent. Comerica Bank and its Affiliates
        may (without having to account therefor to any Lender) accept deposits from,
        lend money to, and generally engage in any kind of banking, trust, financial
        advisory or other business with the Credit Parties as if such Lender were
        not
        acting as the Agent hereunder, and may accept fees and other consideration
        therefor without having to account for the same to the Lenders.

      

      12.13        Agent’s
        Fees.  Until the Indebtedness has been repaid and
        discharged in full and no commitment to extend any credit hereunder is
        outstanding, Borrowers are obligated, on a joint and several basis to pay
        to the
        Agent, as applicable, any agency or other fee(s) set forth (or to be set
        forth
        from time to time) in the applicable Fee Letter on the terms set forth therein.
        The agency fees referred to in this Section 12.13 shall not be refundable
        under
        any circumstances.

      

      12.14        Documentation
        Agent or other Titles.  Any Lender identified on the facing
        page or signature page of this Agreement or in any amendment hereto or as
        designated with consent of the Agent in any assignment agreement as Lead
        Arranger, Documentation Agent, Syndications Agent or any similar titles,
        shall
        not have any right, power, obligation, liability, responsibility or duty
        under
        this Agreement as a result of such title other than those applicable to all
        Lenders as such. Without limiting the foregoing, the Lenders so identified
        shall
        not have or be deemed to have any fiduciary relationship with any Lender
        as a
        result of such title. Each Lender acknowledges that it has not relied, and
        will
        not rely, on the Lender so identified in deciding to enter into this Agreement
        or in taking or not taking action hereunder.

      

      12.15        No
        Reliance on Agent’s Customer Identification
        Program.

      

      (a)           Each
        Lender acknowledges and agrees that neither such Lender, nor any of its
        Affiliates, participants or assignees, may relay on the Agent to carry out
        such
        Lender’s, Affiliate’s, participant’s or assignee’s customer identification
        program, or other obligations required or imposed under or pursuant to the
        Patriot Act or the regulations thereunder, including the regulations contained
        in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”), or
        any other Anti-Terrorism Law, including any programs involving any of the
        following items relating to or in connection with Borrowers or any of their
        Subsidiaries, any of their respective Affiliates or agents, the Loan Documents
        or the transactions hereunder: (i) any identify verification procedures,
        (ii)
        any record keeping, (iii) any comparisons with government lists, (iv) any
        customer notices or (v) any other procedures required under the CIP Regulations
        or such other laws.

      

      (b)           Each
        Lender or assignee or participant of a Lender that is not organized under
        the
        laws of the United States or a state thereof (and is not excepted from the
        certification requirement contained in Section 313 of the USA Patriot Act
        and
        the applicable regulations because it is both (i) an affiliate of a depository
        institution or foreign bank that maintains a physical presence in the United
        States or foreign country, and (ii) subject to provision by a banking authority
        regulating such affiliated depository institution or foreign bank) shall
        deliver
        to the Administrative Agent the certification, or, if applicable,
        recertification, certifying that such Lender is not a “shell” and certifying to
        other matters as required by Section 313 of the Patriot Act and the applicable
        regulations: (x) within 10 days after the Effective Date, and (y) at such
        other
        times as are required under the Patriot Act.

      13.1           Accounting
        Principles.  Where the character or amount of any asset or
        liability or item of income or expense is required to be determined or any
        consolidation or other accounting computation is required to be made for
        the
        purposes of this Agreement, it shall be done, unless otherwise specified
        herein,
        in accordance with GAAP.

      

      13.2           Consent
        to Jurisdiction.  The Borrowers, the Agent and Lenders
        hereby irrevocably submit to the non-exclusive jurisdiction of any United
        States
        Federal Court or Texas state court sitting in Dallas, Texas in any action
        or
        proceeding arising out of or relating to this Agreement or any of the Loan
        Documents and the Borrowers, Agent and Lenders hereby irrevocably agree that
        all
        claims in respect of such action or proceeding may be heard and determined
        in
        any such United States Federal Court or Texas state court. Chapter 346 of
        the
        Texas Finance Code (which regulates certain revolving credit loan accounts
        and
        revolving tri-party accounts) does not apply to this Agreement or the Notes.
        Each Borrower irrevocably consents to the service of any and all process
        in any
        such action or proceeding brought in any court in or of the State of Texas
        by
        the delivery of copies of such process to it at the applicable addresses
        specified on the signature page hereto or by certified mail directed to such
        address or such other address as may be designated by it in a notice to the
        other parties that complies as to delivery with the terms of Section 13.6.
        Nothing in this Section shall affect the right of the Lenders and the Agent
        to
        serve process in any other manner permitted by law or limit the right of
        the
        Lenders or the Agent (or any of them) to bring any such action or proceeding
        against any Credit Party or any of their property in the courts with subject
        matter jurisdiction of any other jurisdiction. Each Borrower irrevocably
        waives
        any objection to the laying of venue of any such suit or proceeding in the
        above
        described courts.

      

      13.3           Law
        of Texas.  This Agreement, the Notes and, the other Loan Documents
        shall be governed by and construed and enforced in accordance with the laws
        of
        the State of Texas. Whenever possible each provision of this Agreement shall
        be
        interpreted in such manner as to be effective and valid under applicable
        law,
        but if any provision of this Agreement shall be prohibited by or invalid
        under
        applicable law, such provision shall be ineffective to the extent of such
        prohibition or invalidity, without invalidating the remainder of such provision
        or the remaining provisions of this Agreement.

      13.4           Interest.  Agent,
        Lenders, Borrowers and any other parties to the Loan Documents intend to
        contract in strict compliance with applicable usury law from time to time
        in
        effect.  In furtherance thereof such Persons stipulate and agree that
        none of the terms and provisions contained in the Loan Documents shall ever
        be
        construed to create a contract to pay, for the use, forbearance or detention
        of
        money, interest in excess of the maximum amount of interest permitted to
        be
        charged by applicable law from time to time in effect.  Neither
        Borrowers, any other party to the Loan Documents nor any present or future
        guarantors, endorsers, or other Persons hereafter becoming liable for payment
        of
        any Indebtedness shall ever be liable for unearned interest thereon or shall
        ever be required to pay interest thereon in excess of the maximum amount
        that
        may be lawfully contracted for, charged, or received under applicable law
        from
        time to time in effect, and the provisions of this section shall control
        over
        all other provisions of the Loan Documents which may be in conflict or apparent
        conflict herewith.  Agent and Lenders expressly disavow any intention
        to contract for, charge, or collect excessive unearned interest or finance
        charges in the event the maturity of any Indebtedness is
        accelerated.  If  (a) the maturity of any Indebtedness is
        accelerated for any reason, (b) any Indebtedness is prepaid and as a result
        any
        amounts held to constitute interest are determined to be in excess of the
        legal
        maximum, or (c) Agent or any Lender or any other holder of any or all of
        the
        Indebtedness shall otherwise collect moneys which are determined to constitute
        interest which would otherwise increase the interest on any or all of the
        Indebtedness to an amount in excess of that permitted to be charged by
        applicable law then in effect, then all sums determined to constitute interest
        in excess of such legal limit shall, without penalty, be promptly applied
        to
        reduce the then outstanding principal of the related Indebtedness or, at
        such
        Lender’s or holder’s option, promptly returned to Borrower or the other payor
        thereof upon such determination.  In determining whether or not the
        interest paid or payable, under any specific circumstance, exceeds the maximum
        amount permitted under applicable law, Agent, Lenders, Borrowers (and any
        other
        payors thereof) shall to the greatest extent permitted under applicable Law,
        (i)
        characterize any non-principal payment as an expense, fee or premium rather
        than
        as interest, (ii) exclude voluntary prepayments and the effects thereof,
        and
        (iii) amortize, prorate, allocate, and spread the total amount of interest
        throughout the entire contemplated term of the instruments evidencing the
        Obligations in accordance with the amounts outstanding from time to time
        thereunder and the maximum legal rate of interest from time to time in effect
        under applicable law in order to lawfully contract for, charge, or receive
        the
        maximum amount of interest permitted under applicable Law.  In the
        event applicable Law provides for an interest ceiling under Chapter 303 of
        the
        Texas Finance Code (the “Texas Finance Code”) as amended, for that day, the
        ceiling shall be the “weekly ceiling” as defined in the Texas Finance Code,
        provided that if any applicable Law permits greater interest, the Law permitting
        the greatest interest shall apply. As used in this section the term “applicable
        law” means the laws of the State of Texas or the laws of the United States of
        America, whichever laws allow the greater interest, as such laws now exist
        or
        may be changed or amended or come into effect in the future.

      

      13.5           Closing
        Costs and Other Costs; Indemnification.

      (a)           Borrowers
        shall pay or reimburse, on a joint and several basis, (a) Agent and its
        Affiliates for payment of, on demand, all reasonable costs and expenses,
        including, by way of description and not limitation, reasonable in-house
        and
        outside attorney fees and advances, appraisal and accounting fees, lien search
        fees, and required travel costs, incurred by Agent and its Affiliates in
        connection with the commitment, consummation and closing of the loans
        contemplated hereby, or in connection with the administration or enforcement
        of
        this Agreement or the other Loan Documents (including the obtaining of legal
        advice regarding the rights and responsibilities of the parties hereto) or
        any
        refinancing or restructuring of the loans or Advances provided under this
        Agreement or the other Loan Documents, or any amendment or modification thereof
        requested by Borrowers, and (b) Agent and its Affiliates and each of the
        Lenders, as the case may be, for all stamp and other taxes and duties payable
        or
        determined to be payable in connection with the execution, delivery, filing
        or
        recording of this Agreement and the other Loan Documents and the consummation
        of
        the transactions contemplated hereby, and any and all liabilities with respect
        to or resulting from any delay in paying or omitting to pay such taxes or
        duties. Furthermore, all reasonable costs and expenses, including without
        limitation attorney fees, incurred by Agent and its Affiliates and, after
        the
        occurrence and during the continuance of an Event of Default, by the Lenders
        in
        revising, preserving, protecting, exercising or enforcing any of its or any
        of
        the Lenders’ rights against Borrowers or any other Credit Party, or otherwise
        incurred by Agent and its Affiliates and the Lenders in connection with any
        Event of Default or the enforcement of the loans (whether incurred through
        negotiations, legal proceedings or otherwise), including by way of description
        and not limitation, such charges in any court or bankruptcy proceedings or
        arising out of any claim or action by any person against Agent, its Affiliates,
        or any Lender which would not have been asserted were it not for Agent’s or such
        Affiliate’s or Lender’s relationship with Borrowers hereunder or otherwise,
        shall also be paid, on a joint and several basis, by Borrowers. All of said
        amounts required to be paid by Borrowers hereunder and not paid forthwith
        upon
        demand, as aforesaid, shall bear interest, from the date incurred to the
        date
        payment is received by Agent, at the Prime-based Rate, plus two percent
        (2%).

      (b)           Borrowers
        jointly and severally agree to indemnify and hold Agent and each of the Lenders
        (and their respective Affiliates) harmless from all loss, cost, damage,
        liability or expenses, including reasonable house and outside attorneys’ fees
        and disbursements (but without duplication of such fees and disbursements
        for
        the same services), incurred by Agent and each of the Lenders by reason of
        an
        Event of Default, or enforcing the obligations of any Credit Party under
        this
        Agreement or any of the other Loan Documents, as applicable, or in the
        prosecution or defense of any action or proceeding concerning any matter
        growing
        out of or connected with this Agreement or any of the Loan Documents, excluding,
        however, any loss, cost, damage, liability or expenses to the extent arising
        as
        a result of the gross negligence or willful misconduct of the party seeking
        to
        be indemnified under this Section 13.5(b), provided that, the Borrowers shall
        be
        obligated to reimburse Agent and the Lenders for only a single financial
        consultant selected by Agent in consultation with the Lenders.

      

      (c)           The
        Borrowers agree on a joint and several basis to defend, indemnify and hold
        harmless Agent and each Lender (and their respective Affiliates), and their
        respective employees, agents, officers and directors from and against any
        and
        all claims, demands, penalties, fines, liabilities, settlements, damages,
        costs
        or expenses of whatever kind or nature (including without limitation, reasonable
        attorneys and consultants fees, investigation and laboratory fees, environmental
        studies required by Agent or any Lender in connection with the violation
        of
        Hazardous Material Laws), court costs and litigation expenses, arising out
        of or
        related to (i) the presence, use, disposal, release or threatened release
        of any
        Hazardous Materials on, from or affecting any premises owned or occupied
        by any
        Credit Party in violation of or the non-compliance with applicable Hazardous
        Material Laws, (ii) any personal injury (including wrongful death) or property
        damage (real or personal) arising out of or related to such Hazardous Materials,
        (iii) any lawsuit or other proceeding brought or threatened, settlement reached
        or governmental order or decree relating to such Hazardous Materials, and/or
        (iv) complying or coming into compliance with all Hazardous Material Laws
        (including the cost of any remediation or monitoring required in connection
        therewith) or any other Requirement of Law; provided, however, that the
        Borrowers shall have no obligations under this Section 13.5(c) with respect
        to
        claims, demands, penalties, fines, liabilities, settlements, damages, costs
        or
        expenses to the extent arising as a result of the gross negligence or willful
        misconduct of the Agent or such Lender, as the case may be. The obligations
        of
        Borrowers under this Section 13.5(c) shall be in addition to any and all
        other
        obligations and liabilities Borrowers may have to Agent or any of the Lenders
        at
        common law or pursuant to any other agreement.

                  overnight courier or by facsimile and addressed or delivered to
                  it at its
                  address set forth on Schedule 13.6 or at such other address as
                  may be

                  notice,
                  if personally delivered or if mailed and properly addressed with
                  postage
                  prepaid and sent by registered or certified mail, shall be deemed
                  given

                  to a
                  reputable overnight courier and properly addressed, shall be deemed

                  but the giver of any such notice shall promptly confirm such notice
                  in

                  shall control. Any notice given by the Agent or any Lender to the
                  Borrower
                  Representative shall be deemed to be a notice to all of the Credit
                  Parties.

              

      

      

      
        	
                 

              	
                (b)

              	
                Notices
                  and other communications provided to the Agent and the Lenders
                  party
                  hereto under this Agreement or any other Loan Document may be delivered
                  or
                  furnished by electronic communication (including email and Internet
                  or
                  intranet websites) pursuant to procedures approved by the
                  Agent.  The Agent or any Borrower may, in its discretion, agree
                  to accept notices and other communications to it hereunder by electronic
                  communications (including email and any E-System) pursuant to procedures
                  approved by it.  Unless otherwise agreed to in a writing by and
                  among the parties to a particular communication, (i) notices and
                  other
                  communications sent to an email address shall be deemed received
                  upon the
                  sender’s receipt of an acknowledgment from the intended recipient (such
                  as
                  by the “return receipt requested” function, return email, or other written
                  acknowledgment) and (ii) notices and other communications posted
                  to any
                  E-System shall be deemed received upon the deemed receipt by the
                  intended
                  recipient at its email address as described in the foregoing clause
                  (i) of
                  notification that such notice or other communication is available
                  and
                  identifying the website address
                  therefore.

      13.7          Further
        Action.  Borrowers, from time to time, upon written request
        of Agent will make, execute, acknowledge and deliver or cause to be made,
        executed, acknowledged and delivered, all such further and additional
        instruments, and take all such further action as may reasonably be required
        to
        carry out the intent and purpose of this Agreement or the Loan Documents,
        and to
        provide for Advances under and payment of the Notes, according to the intent
        and
        purpose herein and therein expressed.

      

      13.8          Successors
        and Assigns; Participations; Assignments.

      

      (a)           This
        Agreement shall be binding upon and shall inure to the benefit of the Borrowers
        and the Lenders and their respective successors and assigns.

      

      (b)           The
        foregoing shall not authorize any assignment by any Borrower of its rights
        or
        duties hereunder, and, except as otherwise provided herein, no such assignment
        shall be made (or be effective) without the prior written approval of the
        Lenders.

      

      (c)           No
        Lenders may at any time assign or grant participations in such Lender’s rights
        and obligations hereunder and under the other Loan Documents except (i) by
        way
        of assignment to any Eligible Assignee in accordance with clause (d) of this
        Section, (ii) by way of a participation in accordance with the provisions
        of
        clause (e) of this Section or (iii) by way of a pledge or assignment of a
        security interest subject to the restrictions of clause (f) of this Section
        (and
        any other attempted assignment or transfer by any Lender shall be deemed
        to be
        null and void).

      

      (d)           Each
        assignment by a Lender of all or any portion of its rights and obligations
        hereunder and under the other Loan Documents, shall be subject to the following
        terms and conditions:

      

      
        	
                 

              	
                (i)

              	
                each
                  such assignment shall be made on a pro rata basis, and shall be
                  in a
                  minimum amount of the lesser of (x) Five Million Dollars ($5,000,000)
                  or
                  such lesser amount as the Agent shall agree and (y) the entire
                  remaining
                  amount of assigning Lender’s aggregate interest in the Revolving Credit
                  (and participations in any outstanding Letters of Credit); provided
                  however that, after giving effect to such assignment, in no event
                  shall
                  the entire remaining amount (if any) of assigning Lender’s aggregate
                  interest in the Revolving Credit (and participations in any outstanding
                  Letters of Credit) be less than $5,000,000;
                  and

              

      

      

      
        	
                 

              	
                (ii)

              	
                the
                  parties to any assignment shall execute and deliver to Agent an
                  Assignment
                  Agreement substantially (as determined by Agent) in the form attached
                  hereto as Exhibit H (with appropriate insertions acceptable to
                  Agent),
                  together with a processing and recordation fee in the amount, if
                  any,
                  required as set forth in the Assignment Agreement (provided however
                  that
                  such Lender need not deliver an Assignment Agreement in connection
                  with
                  assignments to such Lender’s Affiliates or to a Federal Reserve
                  Bank).

              

      

      
        
          
          

        

        
          93

          
            

          

        

        
          
          

        

      

      Until
        the
        Assignment Agreement becomes effective in accordance with its terms, and
        Agent
        has confirmed that the assignment satisfies the requirements of this Section
        13.8, the Borrowers and the Agent shall be entitled to continue to deal solely
        and directly with the assigning Lender in connection with the interest so
        assigned.  From and after the effective date of each Assignment
        Agreement that satisfies the requirements of this Section 13.8, the assignee
        thereunder shall be deemed to be a party to this Agreement, such assignee
        shall
        have the rights and obligations of a Lender under this Agreement and the
        other
        Loan Documents (including without limitation the right to receive fees payable
        hereunder in respect of the period following such assignment) and the assigning
        Lender shall relinquish its rights and be released from its obligations under
        this Agreement and the other Loan Documents.

      

      Upon
        request, Borrowers shall execute and deliver to the Agent, new Note(s) payable
        to the order of the assignee in an amount equal to the amount assigned to
        the
        assigning Lender pursuant to such Assignment Agreement, and with respect
        to the
        portion of the Indebtedness retained by the assigning Lender, to the extent
        applicable, new Note(s) payable to the order of the assigning Lender in an
        amount equal to the amount retained by such Lender hereunder. The Agent,
        the
        Lenders and each Borrower acknowledges and agrees that any such new Note(s)
        shall be given in renewal and replacement of the Notes issued to the assigning
        lender prior to such assignment and shall not effect or constitute a novation
        or
        discharge of the Indebtedness evidenced by such prior Note, and each such
        new
        Note may contain a provision confirming such agreement.

      

      (e)           The
        Borrowers and the Agent acknowledge that each of the Lenders may at any time
        and
        from time to time, subject to the terms and conditions hereof, grant
        participations in such Lender’s rights and obligations hereunder (on a pro rata
        basis only) and under the other Loan Documents to any Person (other than
        a
        natural person or to any Borrower or any of Borrower’s Affiliates or
        Subsidiaries); provided that any participation permitted hereunder shall
        comply
        with all applicable laws and shall be subject to a participation agreement
        that
        incorporates the following restrictions:

      

      
        	
                 

              	
                (i)

              	
                such
                  Lender shall remain the holder of its Notes hereunder (if such
                  Notes are
                  issued), notwithstanding any such
                  participation;

              

      

      

      
        	
                 

              	
                (ii)

              	
                a
                  participant shall not reassign or transfer, or grant any
                  sub-participations in its participation interest hereunder or any
                  part
                  thereof; and

              

      

      
        
          
          

        

        
          94

          
            

          

        

        
          
          

        

      

      
        	
                 

              	
                (iii)

              	
                such
                  Lender shall retain the sole right and responsibility to enforce
                  the
                  obligations of the Credit Parties relating to the Notes and the
                  other Loan
                  Documents, including, without limitation, the right to proceed
                  against any
                  Guarantors, or cause the Agent to do so (subject to the terms and
                  conditions hereof), and the right to approve any amendment, modification
                  or waiver of any provision of this Agreement without the consent
                  of the
                  participant (unless such participant is an Affiliate of such Lender),
                  except for those matters covered by Section 13.10(a) through (e)
                  hereof
                  (provided that a participant may exercise any of the approval rights
                  granted above in this clause (iii) only on an indirect basis, acting
                  through such Lender and the Credit Parties, Agent and the other
                  Lenders
                  may continue to deal directly with such Lender in connection with
                  such
                  Lender’s rights and duties hereunder). Notwithstanding the foregoing,
                  however, in the case of any participation granted by any Lender
                  hereunder,
                  the participant shall not have any rights under this Agreement
                  or any of
                  the other Loan Documents against the Agent, any other Lender or
                  any Credit
                  Party; provided, however that the participant may have rights against
                  such
                  Lender in respect of such participation as may be set forth in
                  the
                  applicable participation agreement and all amounts payable by the
                  Credit
                  Parties hereunder shall be determined as if such Lender had not
                  sold such
                  participation.  Each  such participant shall be
                  entitled to the benefits of Article 11 of this Agreement to the
                  same
                  extent as if it were a Lender and had acquired its interest by
                  assignment
                  pursuant to clause (d) of this Section, provided that no participant
                  shall
                  be entitled to receive any greater amount pursuant to such the
                  provisions
                  of Article 11 than the issuing Lender would have been entitled
                  to receive
                  in respect of the amount of the participation transferred by such
                  issuing
                  Lender to such participant had no such transfer occurred and each
                  such
                  participant shall also be entitled to the benefits of Section 9.6
                  hereof
                  as though it were a Lender, provided that such participant agrees
                  to be
                  subject to Section 10.3 hereof as though it were a
                  Lender.

              

      

      

      (f)           Any
        Lender may at any time pledge or assign a security interest in all or any
        portion of its rights under this Agreement (including its Notes, if any)
        to
        secure obligations of such Lender, including any pledge or assignment to
        secure
        obligations to a Federal Reserve Bank; provided that no such pledge or
        assignment shall release such Lender from any of its obligations hereunder
        or
        substitute any such pledge or assignee for such Lender as a party
        hereto.

      

      (g)           The
        Agent shall maintain at its principal office a copy of each Assignment Agreement
        delivered to it and a register (the “Register”) for the recordation of the names
        and addresses of the Lenders, the Percentages of such Lenders and the principal
        amount of each type of Advance owing to each such Lender from time to time.
        The
        entries in the Register shall be conclusive evidence, absent manifest error,
        and
        the Borrowers, the Agent, and the Lenders may treat each Person whose name
        is
        recorded in the Register as the owner of the Advances recorded therein for
        all
        purposes of this Agreement. The Register shall be available for inspection
        by
        the Borrowers or any Lender upon reasonable notice to the Agent and a copy
        of
        such information shall be provided to any such party on their prior written
        request. The Agent shall give prompt written notice to the Borrower
        Representative of the making of any entry in the Register or any change in
        such
        entry.

      
        
          
          

        

        
          95

          
            

          

        

        
          
          

        

      

      (h)           Each
        Borrower authorizes each Lender to disclose to any prospective assignee or
        participant which has satisfied the requirements hereunder, any and all
        financial information in such Lender’s possession concerning the Credit Parties
        which has been delivered to such Lender pursuant to this Agreement, provided
        that each such prospective assignee or participant shall execute a
        confidentiality agreement consistent with the terms of Section 13.11 hereof
        or
        shall otherwise agree to be bound by the terms thereof.

      

      (i)           Nothing
        in this Agreement, the Notes or the other Loan Documents, expressed or implied,
        is intended to or shall confer on any Person other than the respective parties
        hereto and thereto and their successors and assignees and participants permitted
        hereunder and thereunder any benefit or any legal or equitable right, remedy
        or
        other claim under this Agreement, the Notes or the other Loan
        Documents.

      

      13.9          Counterparts;
        Execution.  This Agreement may be executed in several
        counterparts, and each executed copy shall constitute an original instrument,
        but such counterparts shall together constitute but one and the same
        instrument.  This Agreement (and each other Loan Document) may be
        delivered by facsimile or electronic (e.g., .pdf or .tif file) transmission
        with
        the same effect as if an originally executed version of this Agreement (or
        such
        other Loan Document) had been personally delivered to each of the parties
        hereto, whether or not an original remains in existence.

      

      13.10        Amendment
        and Waiver.  No amendment or waiver of any provision of
        this Agreement or any other Loan Document, nor consent to any departure by
        any
        Credit Party therefrom, shall in any event be effective unless the same shall
        be
        in writing and signed by the Agent and the Majority Lenders (or by the Agent
        at
        the written request of the Majority Lenders) or, if this Agreement expressly
        so
        requires with respect to the subject matter thereof, by all Lenders (and,
        with
        respect to any amendments to this Agreement or the other Loan Documents,
        by any
        Credit Party or the Guarantors that are signatories thereto), and then such
        waiver or consent shall be effective only in the specific instance and for
        the
        specific purpose for which given; provided, however, that no amendment, waiver
        or consent shall, unless in writing and signed by the Lender or Lenders affected
        thereby, do any of the following: (a) increase the stated amount of such
        Lender’s commitment hereunder, (b) reduce the principal
        of, or interest on, any outstanding Indebtedness or any Fees or other amounts
        payable hereunder, (c) postpone any date fixed for any payment of principal
        of,
        or interest on, any outstanding Indebtedness or any Fees or other amounts
        payable hereunder, (d) except as expressly permitted hereunder or under the
        Collateral Documents, release all or substantially all of the Collateral
        (provided that neither Agent nor any Lender shall be prohibited thereby from
        proposing or participating in a consensual or nonconsensual debtor-in-possession
        or similar financing), or release any material guaranty provided by any Person
        in favor of Agent and the Lenders, provided however that Agent shall be
        entitled, without notice to or any further action or consent of the Lenders,
        to

        or
        otherwise transfer in compliance with this Agreement or the other Loan Documents
        or release any guaranty to the extent expressly permitted in this Agreement

        or
        modify any indemnity provided to the Lenders hereunder or under the other

        Revolving Credit Lenders”, Sections 10.2 or 10.3 hereof or this Section 13.10;
        provided, further, that notwithstanding the foregoing, the Revolving Credit
        Maturity Date may be postponed or extended, only with the consent of all
        of the
        Revolving Credit Lenders, and provided further, that no amendment, waiver
        or

        of
        the following: (x) reduce the principal of, or interest on, the Swing Line

        (y) postpone any date fixed for any payment of principal of, or interest
        on, the

      The
        Agent
        shall, upon the written request of the Borrower Representative, execute and
        deliver to the Credit Parties such documents as may be necessary to evidence
        (1)
        the release of any Lien granted to or held by the Agent upon any Collateral:
        (a)
        upon termination of the Revolving Credit Aggregate Commitment and payment
        in
        full of all Indebtedness payable under this Agreement and under any other
        Loan
        Document; (b) which constitutes property (including, without limitation,
        Equity
        Interests in any Person) sold or to be sold or disposed of as part of or
        in
        connection with any disposition (whether by sale, by merger or by any other
        form
        of transaction and including the property of any Subsidiary that is disposed
        of
        as permitted hereby) permitted in accordance with the terms of this Agreement;
        (c) which constitutes property in which a Credit Party owned no interest
        at the
        time the Lien was granted or at any time thereafter; or (d) if approved,
        authorized or ratified in writing by the Majority Lenders, or all the Lenders,
        as the case may be, as provided in this Section 13.10; or (2) the release
        of any
        Person from its obligations under the Loan Documents (including without
        limitation the Guaranty) if all of the Equity Interests of such Person that
        were
        held by a Credit Party are sold or otherwise transferred to any transferee
        other
        than a Borrower or a Subsidiary of a Borrower as part of or in connection
        with
        any disposition (whether by sale, by merger or by any other form of transaction)
        permitted in accordance with the terms of this Agreement; provided that
        (i) Agent shall not be required to execute any such release or subordination
        agreement under clauses (1) or (2) above on terms which, in the Agent’s opinion,
        would expose the Agent to liability or create any obligation or entail any
        consequence other than the release of such Liens without recourse or warranty
        or
        such release shall not in any manner discharge, affect or impair the
        Indebtedness or any Liens upon any Collateral retained by any Credit Party,
        including (without limitation) the proceeds of the sale or other disposition,
        all of which shall constitute and remain part of the Collateral.

       

      13.11        Confidentiality.  Each
        Lender agrees that it will not disclose without the prior consent of the
        Borrower Representative (other than to its employees, its Subsidiaries, another
        Lender, an Affiliate of a Lender or to its auditors or counsel) any information
        with respect to the Credit Parties which is furnished pursuant to this Agreement
        or any of the other Loan Documents; provided that any Lender may disclose
        any
        such information (a) as has become generally available to the public or has
        been
        lawfully obtained by such Lender from any third party under no duty of
        confidentiality to any Credit Party, (b) as may be required or appropriate
        in
        any report, statement or testimony submitted to, or in respect to any inquiry,
        by, any municipal, state or federal regulatory body having or claiming to
        have
        jurisdiction over such Lender, including the Board of Governors of the Federal
        Reserve System of the United States, the Office of the Comptroller of the
        Currency or the Federal Deposit Insurance Corporation or similar organizations
        (whether in the United States or elsewhere) or their successors, (c) as may
        be
        required or appropriate in respect to any summons or subpoena or in connection
        with any litigation, (d) in order to comply with any law, order, regulation,
        ruling or other requirement of law applicable to such Lender, and (e) to
        any
        prospective assignee or participant in accordance with Section 13.8(f)
        hereof.

      13.12        Substitution
        of Lenders.  If (a) any Lender has failed to fund its
        Revolving Credit Percentage of any Revolving Credit Advance, or to fund a
        Revolving Credit Advance to repay a Swing Line Advance or any Reimbursement
        Obligations, (b) the obligation of any Lender to make Eurodollar-based Advances
        has been suspended pursuant to Section 11.3 or 11.4, (c) any Lender has demanded
        compensation under Section 3.4(c), 11.5 or 11.6 or (d) any Lender has not
        approved an amendment, waiver or other modification of this Agreement, if
        such
        amendment or waiver has been approved by the Majority Lenders and the consent
        of
        such Lender is required (in each case, an “Affected Lender”), then the Agent or
        the Borrowers shall have the right to make written demand on the Affected
        Lender
        (with a copy to the Borrower Representative in the case of a demand by the
        Agent
        or with a copy to the Agent in the case of a demand by the Borrowers) to
        assign
        and the Affected Lender shall assign, to one or more financial institutions
        that
        comply with the provisions of Section 13.8 hereof (the “Purchasing Lender” or
“Purchasing Lenders”) to purchase the Advances of the Revolving Credit and/or
        Swing Line, as the case may be, of such Affected Lender (including, without
        limitation, its participating interests in outstanding Swing Line Advances
        and
        Letters of Credit) and assume the commitment of the Affected Lender to extend
        credit under the Revolving Credit (including without limitation its obligation
        to purchase participations interest in Swing Line Advances and Letters of
        Credit) under this Agreement. The Affected Lender shall be obligated to sell
        its
        Advances of the Revolving Credit and/or Swing Line, as the case may be, and
        assign its commitment to extend credit under the Revolving Credit (including
        without limitation its obligations to purchase participations in Swing Line
        Advances and Letters of Credit) to such Purchasing Lender or Purchasing Lenders
        within ten (10) days after receiving notice from the Borrowers requiring
        it to
        do so, at an aggregate price equal to the outstanding principal amount thereof,
        plus unpaid interest accrued thereon up to but excluding the date of the
        sale.
        In connection with any such sale, and as a condition thereof, the Borrowers
        shall pay to the Affected Lender all fees accrued for its account hereunder
        to
        but excluding the date of such sale, plus, if demanded by the Affected Lender
        within ten (10) Business Days after such sale, (i) the amount of any
        compensation which would be due to the Affected Lender under Section 11.1
        if the
        Borrowers had prepaid the outstanding Eurodollar-based Advances of the Affected
        Lender on the date of such sale and (ii) any additional compensation accrued
        for
        its account under Sections 3.4(c), 11.5 and 11.6 to but excluding said date.
        Upon such sale, the Purchasing Lender or Purchasing Lenders shall assume
        the
        Affected Lender’s commitment, and the Affected Lender shall be released from its
        obligations hereunder to a corresponding extent. If any Purchasing Lender
        is not
        already one of the Lenders, the Affected Lender, as assignor, such Purchasing
        Lender, as assignee, the Borrower Representative and the Agent, shall enter
        into
        an Assignment Agreement pursuant to Section 13.8 hereof, whereupon such
        Purchasing Lender shall be a Lender party to this Agreement, shall be deemed
        to
        be an assignee hereunder and shall have all the rights and obligations of
        a
        Lender with a Revolving Credit Percentage equal to its ratable share of the
        then
        applicable Revolving Credit Aggregate Commitment of the Affected Lender.
        In
        connection with any assignment pursuant to this Section 13.12, the Borrowers
        or
        the Purchasing Lender shall pay to the Agent the administrative fee for
        processing such assignment referred to in Section 13.8.

      13.13        Withholding
        Taxes.  If any Lender is not a “united states person”
within the meaning of Section 7701(a)(30) of the Internal Revenue
        Code, such
        Lender shall promptly (but in any event prior to the initial payment of interest
        hereunder or prior to its accepting any assignment under Section 13.8 hereof,
        as
        applicable) deliver to the Agent two executed copies of (i) Internal Revenue
        Service Form W-8BEN or any successor form specifying the applicable tax treaty
        between the United States and the jurisdiction of such Lender’s domicile which
        provides for the exemption from withholding on interest payments to such
        Lender,
        (ii) Internal Revenue Service Form W-8ECI or any successor form evidencing
        that
        the income to be received by such Lender hereunder is effectively connected
        with
        the conduct of a trade or business in the United States or (iii) other evidence
        satisfactory to the Agent that such Lender is exempt from United States income
        tax withholding with respect to such income; provided, however, that such
        Lender
        shall not be required to deliver to Agent the aforesaid forms or other evidence
        with respect to Advances to Borrowers, if such Lender has assigned its entire
        interest hereunder (including its Revolving Credit Commitment Amount, any
        outstanding Advances hereunder and participations in Letters of Credit issued
        hereunder and any Notes issued to it by Borrowers), to an Affiliate which
        is
        incorporated under the laws of the United States or a state thereof, and
        so
        notifies the Agent. Such Lender shall amend or supplement any such form or
        evidence as required to insure that it is accurate, complete and non-misleading
        at all times. Promptly upon notice from the Agent of any determination by
        the
        Internal Revenue Service that any payments previously made to such Lender
        hereunder were subject to United States income tax withholding when made,
        such
        Lender shall pay to the Agent the excess of the aggregate amount required
        to be
        withheld from such payments over the aggregate amount actually withheld by
        the
        Agent. In addition, from time to time upon the reasonable request and the
        sole
        expense of Borrower, each Lender and the Agent shall (to the extent it is
        able
        to do so based upon applicable facts and circumstances), complete and provide
        Borrowers with such forms, certificates or other documents as may be reasonably
        necessary to allow Borrowers, as applicable, to make any payment under this
        Agreement or the other Loan Documents without any withholding for or on the
        account of any tax under Section 10.1(d) hereof (or with such withholding
        at a
        reduced rate), provided that the execution and delivery of such forms,
        certificates or other documents does not adversely affect or otherwise restrict
        the rights and benefits (including without limitation economic benefits)
        available to such Lender or the Agent, as the case may be, under this Agreement
        or any of the other Loan Documents, or under or in connection with any
        transactions not related to the transactions contemplated hereby.

      

      13.14        Taxes
        and Fees.  Should any tax (other than as a result of a
        Lender’s failure to comply with Section 13.13 or a tax based upon the net income
        or capitalization of any Lender or the Agent by any jurisdiction where a
        Lender
        or the Agent is or has been located), or recording or filing fee become payable
        in respect of this Agreement or any of the other Loan Documents or any
        amendment, modification or supplement hereof or thereof, Borrowers agrees
        to pay
        the same, together with any interest or penalties thereon arising from any
        Borrower’s actions or omissions, and agrees to hold the Agent and the Lenders
        harmless with respect thereto provided, however, that Borrowers shall not
        be
        responsible for any such interest or penalties which were incurred prior
        to the
        date that notice is given to the Credit Parties of such tax or
        fees. Notwithstanding the foregoing, nothing contained in
        this Section 13.14 shall affect or reduce the rights of any Lender or the
        Agent
        under Section 11.5 hereof.

      13.15        WAIVER
        OF JURY TRIAL.  THE LENDERS, THE AGENT AND THE BORROWERS
        KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM MAY
        HAVE TO
        A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT
        OR
        ANY RELATED INSTRUMENT OR AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED
        BY
        THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL
        OR
        WRITTEN) OR ACTION OF ANY OF THEM. NEITHER THE LENDERS, THE AGENT NOR THE
        BORROWERS SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY SUCH
        ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH
        A
        JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. THESE PROVISIONS SHALL NOT BE
        DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY THE LENDERS
        AND
        THE AGENT OR THE BORROWER EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL
        OF
        THEM.

      

      13.16        Patriot
        Act Notice.   Pursuant to Section 326 of the USA
        Patriot Act, the Agent and the Lenders hereby notify the Credit Parties that
        if
        they or any of their Subsidiaries open an account, including any loan, deposit
        account, treasury management account, or other extension of credit with Agent
        or
        any Lender, the Agent or the applicable Lender will request the applicable
        Person’s name, tax identification number, business address and other information
        necessary to identify such Person (and may request such Person’s organizational
        documents or other identifying documents) to the extent necessary for the
        Agent
        and the applicable Lender to comply with the USA Patriot Act.

        AGREEMENTS” (AS DEFINED IN SECTION 26.02(A)(2) OF THE TEXAS BUSINESS &
COMMERCE CODE, AS AMENDED) REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES,
        AND THIS AGREEMENT AND THE OTHER WRITTEN LOAN AGREEMENTS MAY NOT BE CONTRADICTED
        BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS BETWEEN
        THE
        PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
        PARTIES.  In the event of any conflict between the terms of this
        Agreement and the other Loan Documents, this Agreement shall
        govern.

        illegal or unenforceable in any jurisdiction, the validity, legality and
        enforceability of the remaining obligations of the Credit Parties shall not
        in
        any way be affected or impaired thereby, and such invalidity, illegality
        or
        unenforceability in one jurisdiction shall not affect the validity, legality
        or

      13.20        Construction
        of Certain Provisions.  If any provision of this Agreement
        or any of the Loan Documents refers to any action to be taken by any Person,
        or
        which such Person is prohibited from taking, such provision shall be applicable
        whether such action is taken directly or indirectly by such Person, whether
        or
        not expressly specified in such provision.

      

      13.21        Independence
        of Covenants.  Each covenant hereunder shall be given
        independent effect (subject to any exceptions stated in such covenant) so
        that
        if a particular action or condition is not permitted by any such covenant
        (taking into account any such stated exception), the fact that it would be
        permitted by an exception to, or would be otherwise within the limitations
        of,
        another covenant shall not avoid the occurrence of a Default or an Event
        of
        Default.

        Transmissions.

      

      
        	
                 

              	
                (a)

              	
                Each
                  of the Agent, the Credit Parties, the Lenders, and each of their
                  Affiliates is authorized (but not required) to transmit, post or
                  otherwise
                  make or communicate, in its sole discretion, Electronic Transmissions
                  in
                  connection with any Loan Document and the transactions contemplated
                  therein.  Each Borrower and each other Credit Party hereby
                  acknowledges and agrees that the use of Electronic Transmissions
                  is not
                  necessarily secure and that there are risks associated with such
                  use,
                  including risks of interception, disclosure and abuse and each

                  as
                  a joint and several obligor. It is the intention of the parties
                  that with
                  respect to liability of any Borrower hereunder arising solely by
                  reason of
                  its being jointly and severally liable for Advances and other extensions
                  of credit taken by Borrower, the obligations of such Borrower shall

                  shall continue to be effective or be reinstated, as the case may

                  any time any payment (in whole or in part) of any of the Indebtedness
                  is
                  rescinded or must be restored by any Lender or any holder of any

                  as the
                  case may be, as though such payment had not been

                  remedy
                  shall operate as a waiver thereof, and no single or partial exercise
                  by
                  any of the Lenders of any right or remedy shall preclude other
                  or further
                  exercise thereof or the exercise of any other right or remedy.
                  No action

                  that it now has and will continue to have independent means of
                  obtaining
                  information concerning the Borrowers’ affairs, financial condition and
                  business. Lenders shall not have any duty or responsibility to

                  Borrower with any credit or other information concerning such Borrower’s
                  affairs, financial condition or business which may come into the

                Each
                  of the Borrowers represents and warrants (i) that the business
                  operations
                  of the Borrowers are interrelated and that the business operations
                  of the
                  Borrowers complement one another, and such entities have a common
                  business
                  purpose, and (ii) that, to permit their uninterrupted and continuous
                  operations, such entities now require and will from time to time
                  hereafter
                  require funds and credit accommodations for general business purposes
                  and
                  that (iii) the proceeds of advances under the Revolving Credit,
                  the Swing
                  Line, and the other credit facilities extended hereunder will directly
                  or
                  indirectly benefit the Borrowers hereunder, severally and jointly,
                  regardless of which Borrower receives part or all of the proceeds
                  of such
                  Advances.

                Notwithstanding
                  anything to the contrary contained herein, it is the intention
                  of the
                  Borrowers, Agent and the Lenders that the amount of the respective
                  Borrowers’ obligations hereunder shall be in, but not in excess of, the
                  maximum amount thereof not subject to avoidance or recovery by
                  operation
                  of applicable law governing bankruptcy, reorganization, arrangement,
                  adjustment of debts, relief of debtors, dissolution, insolvency,
                  fraudulent transfers or conveyances or other similar laws (collectively,
                  “Applicable Insolvency Laws”). To that end, but only in the event and to
                  the extent that the Borrowers’ respective obligations hereunder or any
                  payment made pursuant thereto would, but for the operation of the
                  foregoing proviso, be subject to avoidance or recovery under Applicable
                  Insolvency Laws, the amount of the Borrowers’ respective obligations
                  hereunder shall be limited to the largest amount which, after giving
                  effect thereto, would not, under Applicable Insolvency Laws, render
                  the
                  Borrower’s respective obligations hereunder unenforceable or avoidable or
                  subject to recovery under Applicable Insolvency Laws. To the extent
                  any
                  payment actually made hereunder exceeds the limitation contained
                  in this
                  Section 13.25(g), then the amount of such excess shall, from and
                  after the
                  time of payment by the Borrowers (or any of them), be reimbursed
                  by the
                  Lenders upon demand by such Borrowers. The foregoing proviso is
                  intended
                  solely to preserve the rights of the Agent and the Lenders hereunder
                  against the Borrowers to the maximum extent permitted by Applicable
                  Insolvency Laws and neither any Borrower nor any Guarantor nor
                  any other
                  Person shall have any right or claim under this Section 13.25(g)
                  that
                  would not otherwise be available under Applicable Insolvency
                  Laws.

                  Claims.  Except as set forth on
                  Schedule 1.1 or as otherwise disclosed to the
                  Agent in writing, no material claim has been made and is continuing
                  or, to
                  any Debtor’s knowledge, threatened that the use by any Debtor of any
                  material item of Intellectual Property Collateral is invalid or
                  unenforceable or that the use by any Debtor of any Intellectual
                  Property
                  Collateral does or may violate the rights of any Person. To the
                  Debtors’
                  knowledge, there is no infringement or unauthorized use of any
                  item of
                  Intellectual Property Collateral contained on Schedule
                  1.1 or as otherwise disclosed to the Agent in
                  writing.

                  Consent.  Except as disclosed in writing to the
                  Agent, no consent of any party (other than such Debtor) to any
                  Patent
                  License, Copyright License or Trademark License constituting Intellectual
                  Property Collateral is required, or purports to be required, to

                  obtained by or on behalf of such Debtor in connection with the
                  execution,
                  delivery and performance of this Agreement that has not been obtained.
                  Each Patent License, Copyright License and Trademark License constituting
                  Intellectual Property Collateral is in full force and effect and
                  constitutes a valid and legally enforceable obligation of the applicable
                  Debtor and (to the knowledge of the Debtors) each other party thereto
                  except as enforceability may be limited by bankruptcy, insolvency,
                  reorganization, moratorium or similar laws affecting the enforcement
                  of
                  creditor’s rights generally and by general equitable principles (whether
                  enforcement is sought by proceedings in equity or at

      Covenants

       

      Each
        Debtor covenants and agrees with the Agent, until termination of this Agreement
        in accordance with the provisions of Section
        7.12 hereof, as follows:

       

      Section
        4.1      Covenants Regarding Certain Kinds of
        Collateral.

       

      (a)    Promissory
        Notes and Tangible Chattel Paper.  If
        Debtors, now or at any time hereafter, collectively hold or acquire any
        promissory notes or tangible Chattel Paper for which the principal amount
        thereof or the obligations evidenced thereunder are, in the aggregate, in
        excess
        of $500,000, the applicable Debtors shall promptly notify the Agent in writing
        thereof and forthwith endorse, collaterally assign and deliver the same to
        the
        Agent, accompanied by such instruments of transfer or assignment duly executed
        in blank as the Agent may from time to time reasonably specify, and cause
        all
        such Chattel Paper to bear a legend reasonably acceptable to the Agent
        indicating that the Agent has a security interest in such Chattel
        Paper.

      (b)    Electronic
        Chattel Paper and Transferable Records.  If Debtors, now
        or at any time hereafter, collectively hold or acquire an interest in any
        electronic Chattel Paper or any “transferable record,” as that term is defined
        in the federal Electronic Signatures in Global and National Commerce Act,
        or in
        the Uniform Electronic Transactions Act as in effect in any relevant
        jurisdiction, worth, in the aggregate, in excess of $500,000, the applicable
        Debtors shall promptly notify the Agent thereof and, at the reasonable request
        and option of the Agent, shall take such action as the Agent may reasonably
        request to vest in the Agent control, under Section 9-105 of the UCC, of
        such
        electronic chattel paper or control under the federal Electronic Signatures
        in
        Global and National Commerce Act, or the Uniform Electronic Transactions
        Act, as
        so in effect in such jurisdiction, of such transferable record.

       

      (c)    Letter-of-Credit
        Rights.  If Debtors, now or at any time hereafter,
        collectively are or become beneficiaries under letters of credit, with an
        aggregate face amount in excess of $500,000, the applicable Debtors shall
        promptly notify the Agent thereof and, at the request of the Agent, the
        applicable Debtors shall, pursuant to an agreement in form and substance
        reasonably satisfactory to the Agent either arrange (i) for the issuer and
        any
        confirmer of such letters of credit to consent to an assignment to the Agent
        of
        the proceeds of the letters of credit or (ii) for the Agent to become the
        transferee beneficiary of the letters of credit, together with, in each case,
        any such other actions as reasonably requested by the Agent to perfect its
        first
        priority Lien in such letter of credit rights.  The applicable Debtor
        shall retain the proceeds of the applicable letters of credit until an Event
        of
        Default has occurred and is continuing whereupon the proceeds are to be
        delivered to the Agent and applied as set forth in the Credit
        Agreement.

       

      (d)    Commercial
        Tort Claims.  If Debtors, now or at any time hereafter,
        collectively hold or acquire any commercial tort claims, which, the reasonably
        estimated value of which are in aggregate excess of $500,000, the applicable
        Debtors shall immediately notify the Agent in a writing signed by such Debtors
        of the particulars thereof and grant to the Agent in such writing a security
        interest therein and in the proceeds thereof, all upon the terms of this
        Agreement, with such writing to be in form and substance reasonably satisfactory
        to the Agent.

       

      (e)    Pledged
        Shares.  All certificates or instruments
        representing or evidencing the Pledged Shares or any Debtor’s rights therein
        shall be delivered to the Agent promptly upon Debtor gaining any rights therein,
        in suitable form for transfer by delivery or accompanied by duly executed
        stock
        powers or instruments of transfer or assignments in blank, all in form and
        substance reasonably acceptable to the Agent.

                  that any of
                  the foregoing is not of material economic value to them. Each Debtor
                  agrees to take corresponding steps with respect to each new or

                  its commercially reasonable judgment, that any of the foregoing
                  is not of
                  material economic value to it. Any expenses incurred in connection

                  to protect such Intellectual Property Collateral, including, without
                  limitation, suing for infringement or misappropriation and for
                  an
                  injunction against such infringement or misappropriation. Any expense
                  incurred in connection with such activities shall be borne by the
                  Debtors.
                  Each Debtor will advise the Agent promptly and in writing, in reasonable
                  detail, of any adverse determination or the institution of any
                  proceeding
                  (including, without limitation, the institution of any proceeding
                  in the
                  United States Patent and Trademark Office, the United States Copyright
                  Office or any court) regarding any material item of the Intellectual
                  Property Collateral.

                  quarter; and execute and deliver, or take such other actions as
                  may be
                  reasonably required by Agent for the Agent to record its Lien on

                  to make any
                  filings as may be reasonably necessary to perfect the Agent’s Lien on its
                  aircraft and vessels, unless (i) a Default or an Event of Default
                  has
                  occurred and is continuing, whereupon the Agent may require such
                  filings
                  be made or (ii) such Debtor, either singly, or together with the
                  other
                  Debtors, owns aircraft and vessels which have a fair market value
                  of at
                  least $_______, in aggregate amount, whereupon the applicable Debtors
                  shall provide prompt notice to the Agent, and the Agent, at its
                  option and
                  request, may require the applicable Debtors to execute such agreements
                  and
                  make such filings as may be reasonably necessary to perfect the

      Section
        4.2      Encumbrances.  Each
        Debtor shall not create, permit or suffer to exist, and shall defend the
        Collateral against any Lien (other than the Permitted Liens, provided that
        no
        Lien, other than the Lien created hereunder, shall exist over the Pledged
        Shares) or any restriction upon the pledge or other transfer thereof (other
        than
        as specifically permitted in the Credit Agreement), and shall defend such
        Debtor’s title to and other rights in the Collateral and the Agent’s pledge and
        collateral assignment of and security interest in the Collateral against

        or any
        portion thereof under Section
        7.13 hereof (but only to the extent of any
        Collateral so released), such Debtor shall do nothing to impair the rights
        of
        the Agent in the Collateral.

        Each Debtor shall not change its respective name, identity, corporate structure
        or jurisdiction of organization, or identification number in any manner that
        might make any financing statement filed in connection with this Agreement
        seriously misleading within the meaning of Section 9-506 of the UCC unless
        such
        Debtor shall have given the Agent fifteen (15) days prior written notice
        with
        respect to any change in such Debtor’s corporate structure, jurisdiction of
        organization, name or identity and shall have taken all action deemed reasonably
        necessary by the Agent under the circumstances to protect its Liens and the
        perfection and priority thereof, (b) each Debtor shall keep the Records at
        the
        location specified on Schedule 3.2 as the location of
        such books and records or as otherwise specified in writing to the Agent
        and (c)
        the Debtors shall permit the Agent, the Lenders, and their respective agents
        and
        representatives to conduct inspections, discussion and audits of the Collateral

        under the Credit Agreement) that has attached to or been made or asserted
        against any of the Collateral upon becoming aware of the existence of such
        Lien.

                  Debtor shall execute and deliver (or cause to be executed and delivered)
                  to the Agent all such proxies and other instruments as the Agent
                  may
                  reasonably request for the purpose of enabling the Agent to exercise
                  the
                  voting and other rights which it is entitled to exercise pursuant
                  to this
                  Section 4.7(a)(ii) and to receive the dividends,

                  and
                  retain pursuant to this Section 4.7(a)(ii). The
                  foregoing shall not in any way limit the Agent’s power and authority

      (b)    Possession;
        Reasonable Care.  Regardless
        of whether a Default or an Event of Default has occurred or is continuing,
        the
        Agent shall have the right to hold in its possession all Pledged Shares pledged,
        collaterally assigned or transferred hereunder and from time to time
        constituting a portion of the Collateral.  The Agent may appoint one
        or more agents (which in no case shall be a Debtor or an affiliate of a Debtor)
        to hold physical custody, for the account of the Agent, of any or all of
        the
        Collateral.  The Agent shall be deemed to have exercised reasonable
        care in the custody and preservation of the Collateral in its possession
        if the
        Collateral is accorded treatment substantially equal to that which the Agent
        accords its own property, it being understood that the Agent shall not have
        any
        responsibility for (i) ascertaining or taking action with respect to calls,
        conversions, exchanges, maturities, tenders or other matters relative to
        any
        Collateral, whether or not the Agent has or is deemed to have knowledge of
        such
        matters, or (ii) taking any necessary steps to preserve rights against any
        parties with respect to any Collateral, except, subject to the terms hereof,
        upon the written instructions of the Lenders.  Following the

                  after the date hereof) to issue to such Debtor or any of such Debtor’s
                  other Subsidiaries any shares of stock, membership interests, partnership

                  for any
                  of the Collateral, unless, concurrently with each issuance thereof,

                  and all such shares of stock, membership interests, partnership
                  units,
                  notes or instruments are encumbered in favor of the Agent under
                  this
                  Agreement or otherwise (it being understood and agreed that all
                  such

                  Debtor or the Agent, be automatically encumbered by this Agreement
                  as

                  in
                  substantially the form of Exhibit A hereto in

                  by the
                  Lenders, a new stock pledge, duly executed by the applicable Debtor,
                  in
                  substantially the form of this Agreement (a “New
                  Pledge”), in respect of such shares of stock, membership

                  same, together with such other documentation as the Agent may reasonably
                  request. Such Debtor hereby (x) authorizes the Agent to attach

                  amendment to this Agreement, (y) agrees that all such shares of

                  otherwise acquired by any Debtor after the date hereof, and with
                  respect

                  Office
                  at the time such Collateral is pledged by a Debtor to the Agent
                  pursuant
                  to this Security Agreement, and which is subsequently registered
                  or filed
                  by such Debtor in the appropriate office and which is material
                  to such

                  registration thereof execute or cause to be executed and delivered
                  to the
                  Agent, (i) an amendment, duly executed by such Debtor, in substantially
                  the form of Exhibit A hereto, in respect of such
                  additional or newly registered collateral or (ii) at the Agent’s option, a
                  new security agreement, duly executed by the applicable Debtor,
                  in
                  substantially the form of this Agreement, in respect of such additional
                  or
                  newly registered collateral, granting to the Agent, for the benefit
                  of the
                  Lenders, a first priority security interest, pledge and Lien thereon
                  (subject only to the Permitted Liens), together in each case with
                  all
                  certificates, notes or other instruments representing or evidencing
                  the
                  same, and shall, upon the Agent’s reasonable request, execute or cause to
                  be executed any financing statement or other document (including
                  without
                  limitation, filings required by the U.S. Patent and Trademark Office
                  and/or the U.S. Copyright Office in connection with any such additional
                  or

                  Lien over
                  such new Intellectual Property Collateral.  Each Debtor hereby
                  (x) authorizes the Agent to attach each amendment to this Agreement,
                  (y)
                  agrees that all such additional collateral listed in any amendment
                  delivered to the Agent shall for all purposes hereunder constitute
                  Collateral, and (z) is deemed to have made, upon the delivery of
                  each such
                  Amendment, the representations and warranties contained in
                  Section 3.3(d) and Section
                  3.5 of this Agreement with respect to the Collateral

      Section
        4.9      Further Assurances  
(a)  At
        any time and from time to time, upon the reasonable request of the Agent,
        and at
        the sole expense of the Debtors, each Debtor shall promptly execute and deliver
        all such further agreements, documents and instruments and take such further
        action as the Agent may reasonably deem necessary or appropriate to (i)
        preserve, ensure the priority, effectiveness and validity of and perfect
        the
        Agent’s security interest in and pledge and collateral assignment of the
        Collateral (including causing the Agent’s name to be noted as secured party on
        any certificate of title for a titled good if such notation is a condition
        of
        the Agent’s ability to enforce its security interest in such Collateral), unless
        such actions are specifically waived under the terms of this Agreement and
        the
        other Loan Documents, (ii) carry out the provisions and purposes of this
        Agreement and (iii) to enable the Agent to exercise and enforce its rights
        and
        remedies hereunder with respect to any of the Collateral.  Except as
        otherwise expressly permitted by the terms of the Credit Agreement relating
        to
        disposition of assets and except for Permitted Liens (except for Pledged
        Shares,
        over which the only Lien shall be that Lien established under this Agreement),
        each Debtor agrees to maintain and preserve the Agent’s security interest in and
        pledge and collateral assignment of the Collateral hereunder and the priority
        thereof.  Notwithstanding anything contained herein to the contrary,
        the Agent need not require the creation or perfection of pledges of or security
        interests in particular assets if and for so long as, in the reasonable judgment
        of the Agent, the cost of creating or perfecting such pledges or security
        interests in such assets shall be excessive in view of the benefits to be
        obtained by the Agent therefrom.  The Agent may, in its sole
        discretion, grant extensions of time for the perfection of security interests
        in
        particular assets (including extensions beyond the Effective Date for the
        perfection of security interests in the assets of the Debtors on such date)
        where it reasonably determines, in consultation with the Debtors, that
        perfection cannot be accomplished without undue effort or expense by the
        time or
        times at which it would otherwise be required by this Agreement or the other
        Loan Documents.

      (b)          Each
        Debtor hereby irrevocably authorizes the Agent (until the termination of
        this
        Agreement in accordance with the provisions of this Agreement) at any time
        and
        from time to time to file in any filing office in any jurisdiction any initial
        financing statements and amendments thereto that (i) indicate any or all
        of the
        Collateral upon which the Debtors have granted a Lien (including, without
        limitation, the filing of a financing statement describing the Collateral
        as
“all assets in which Debtor now owns or hereafter acquires rights”, “all
        assets”, “all personal property” or words of similar import), and (ii) provide
        any other information required by Part 5 of Article 9 of the UCC, including
        organizational information and in the case of a fixture filing or a filing
        for
        Collateral consisting of as-extracted collateral or timber to be cut, a
        sufficient description of real property to which the Collateral
        relates.  Each Debtor agrees to furnish any such information required
        by the preceding paragraph to the Agent promptly upon request.

                  to sell, transfer, pledge, convey, make any agreement with respect
                  to, or
                  otherwise deal with, any of the Collateral as fully and completely
                  as
                  though the Agent were the absolute owner thereof for all purposes,
                  and to
                  do, at the Agent’s option and such Debtor’s expense, at any time, or from
                  time to time, all acts and things which the Agent reasonably deems
                  necessary to protect, preserve, maintain, or realize upon the Collateral
                  and the Agent’s security interest
                  therein.

      This
        power of attorney is a power coupled with an interest and shall be
        irrevocable.  The Agent shall be under no duty to exercise or withhold
        the exercise of any of the rights, powers, privileges and options expressly
        or
        implicitly granted to the Agent in this Agreement, and shall not be liable
        for
        any failure to do so or any delay in doing so.  This power of attorney
        is conferred on the Agent solely to protect, preserve, maintain and realize
        upon
        its security interest in the Collateral.  The Agent shall not be
        responsible for any decline in the value of the Collateral and shall not
        be
        required to take any steps to preserve rights against prior parties or to
        protect, preserve or maintain any Lien given to secure the
        Collateral.

       

      Section
        5.2     Setoff.  In
        addition to and not in limitation of any rights of any Lenders under applicable
        law, the Agent and each Lender shall, upon the occurrence and continuance
        of an
        Event of Default, without notice or demand of any kind, have the right to
        appropriate and apply to the payment of the Indebtedness owing to it (whether
        or
        not then due) any and all balances, credits, deposits, accounts or moneys
        of
        Debtors then or thereafter on deposit with such Lenders; provided, however,
        that
        any such amount so applied by any Lender on any of the Indebtedness owing
        to it
        shall be subject to the provisions of the Credit Agreement.

       

      Section
        5.3      Assignment by the
        Agent.  The
        Agent may at any time assign or otherwise transfer all or any portion of
        its
        rights and obligations as the Agent under this Agreement and the other Loan
        Documents (including, without limitation, the Indebtedness) to any other
        Person,
        to the extent permitted by, and upon the conditions contained in, the Credit
        Agreement and such Person shall thereupon become vested with all the benefits
        and obligations thereof granted to the Agent herein or otherwise.

      Section
        5.4     Performance by the
        Agent.
        If any
        Debtor shall fail to perform any covenant or agreement contained in this
        Agreement after demand from Agent to so perform, the Agent may (but shall
        not be
        obligated to) perform or attempt to perform such covenant or agreement on
        behalf
        of the Debtors, in which case Agent shall exercise good faith and make diligent
        efforts to give Debtors prompt prior written notice of such performance or
        attempted performance.  In such event, the Debtors shall, at the
        request of the Agent, promptly pay any reasonable amount expended by the
        Agent
        in connection with such performance or attempted performance to the Agent,
        together with interest thereon at the interest rate set forth in the Credit
        Agreement, from and including the date of such expenditure to but excluding
        the
        date such expenditure is paid in full.  Notwithstanding the foregoing,
        it is expressly agreed that the Agent shall not have any liability or
        responsibility for the performance (or non-performance) of any obligation
        of the
        Debtors under this Agreement.

       

      Section
        5.5      Certain Costs and
        Expenses.  The
        Debtors shall pay or reimburse the Agent within five (5) Business Days after
        demand for all reasonable costs and expenses (including reasonable attorney’s
        and paralegal fees) incurred by it in connection with the enforcement, attempted
        enforcement, or preservation of any rights or remedies under this Agreement
        or
        any other Loan Document during the existence of an Event of Default or after
        acceleration of any of the Indebtedness (including in connection with any
        “workout” or restructuring regarding the Indebtedness, and including in any
        insolvency proceeding or appellate proceeding).  The agreements in
        this Section 5.5 shall survive the
        payment in full of the Indebtedness.  Notwithstanding the foregoing,
        the reimbursement of any fees and expenses incurred by the Lenders shall
        be
        governed by the terms and conditions of the applicable Credit
        Agreement.

       

      Section
        5.6      Indemnification.  Each
        of the Debtors agrees to indemnify and hold Agent and each of the Lenders
        (and
        their respective Affiliates) and their respective employees, agents, officers,
        directors, counsel, and attorneys-in-fact harmless from all loss, cost, damage,
        liability or expenses, including reasonable house and outside attorneys’ and
        paralegals’ fees and disbursements (but without duplication of such fees and
        disbursements for the same services), incurred by Agent and each of the Lenders
        by reason of a Default or an Event of Default, or enforcing the obligations
        of
        any Debtor under this Agreement or any of the other Loan Documents, or as
        a
        result of any actual or claimed violation of law, as applicable, or in the
        prosecution or defense of any action or proceeding concerning any matter
        growing
        out of or connected with this Agreement or any of the Loan Documents,
INCLUDING CLAIMS, DAMAGES, FINES, EXPENSES, LIABILITIES OR CAUSES
        OF
        ACTION OF WHATEVER KIND RESULTING FROM THE AGENT’S OR ANY LENDER’S OWN
        NEGLIGENCE except to the extent (but only to the extent) caused by
        Agent’s or any Lender’s gross negligence or willful misconduct.  The
        agreements in this Section
        5.6 shall survive payment of all other
        Indebtedness.

      Section
        6.1      Rights and
        Remedies.  If
        an Event of Default shall have occurred and be continuing, the Agent shall
        have
        the following rights and remedies subject to the direction and/or consent
        of the
        Lenders as required under the Credit Agreement:

       

      
        	
                 

              	
                (a)

              	
                The
                  Agent may exercise any of the rights and remedies set forth in
                  this
                  Agreement (including, without limitation, Article
                  5 hereof), in the Credit Agreement, or in any other
                  Loan
                  Document, or as provided by applicable
                  law.

              

      

       

      
        	
                 

              	
                (b)

              	
                In
                  addition to all other rights and remedies granted to the Agent
                  in this
                  Agreement, the Credit Agreement or by applicable law, the Agent
                  shall have
                  all of the rights and remedies of a secured party under the UCC
                  (whether
                  or not the UCC applies to the affected Collateral) and the Agent
                  may also,
                  without previous demand or notice except as specified below or
                  in the
                  Credit Agreement, sell the Collateral or any part thereof in one
                  or more
                  parcels at public or private sale, at any exchange, broker’s board or at
                  any of the Agent’s offices or elsewhere, for cash, on credit or for future
                  delivery, and upon such other terms as the Agent may, in its reasonable
                  discretion, deem commercially reasonable or otherwise as may be
                  permitted
                  by law.  Without limiting the generality of the foregoing, the
                  Agent may (i) without demand or notice to the Debtors (except as
                  required
                  under the Credit Agreement or applicable law), collect, receive
                  or take
                  possession of the Collateral or any part thereof, and for that
                  purpose the
                  Agent (and/or its Agents, servicers or other independent contractors)
                  may
                  enter upon any premises on which the Collateral is located and
                  remove the
                  Collateral therefrom or render it inoperable, and/or (ii) sell,
                  lease or
                  otherwise dispose of the Collateral, or any part thereof, in one
                  or more
                  parcels at public or private sale or sales, at the Agent’s offices or
                  elsewhere, for cash, on credit or for future delivery, and upon
                  such other
                  terms as the Agent may, in its reasonable discretion, deem commercially
                  reasonable or otherwise as may be permitted by law.  The
                  Agent and, subject to the terms of the Credit
                  Agreement, each of the Lenders shall have the right at any public
                  sale or
                  sales, and, to the extent permitted by applicable law, at any private
                  sale
                  or sales, to bid (which bid may be, in whole or in part, in the
                  form of
                  cancellation of indebtedness) and become a purchaser of the Collateral
                  or
                  any part thereof free of any right of redemption on the part of
                  the
                  Debtors, which right of redemption is hereby expressly waived and
                  released
                  by the Debtors to the extent permitted by applicable law.  The
                  Agent may require the Debtors to assemble the Collateral and make
                  it
                  available to the Agent at any place designated by the Agent to
                  allow the
                  Agent to take possession or dispose of such Collateral.  The
                  Debtors agree that the Agent shall not be obligated to give more
                  than five
                  (5) days prior written notice of the time and place of any public
                  sale or
                  of the time after which any private sale may take place and that
                  such
                  notice shall constitute reasonable notice of such matters.  The
                  foregoing shall not require notice if none is required by applicable
                  law.  The Agent shall not be obligated to make any sale of
                  Collateral if, in the exercise of its reasonable discretion, it
                  shall
                  determine not to do so, regardless of the fact that notice of sale
                  of
                  Collateral may have been given.  The Agent may, without notice
                  or publication (except as required by applicable law), adjourn
                  any public
                  or private sale or cause the same to be adjourned from time to
                  time by
                  announcement at the time and place fixed for sale, and such sale
                  may,
                  without further notice, be made at the time and place to which
                  the same
                  was so adjourned.  The Debtors shall be liable for all
                  reasonable expenses of retaking, holding, preparing for sale or
                  the like,
                  and all reasonable attorneys’ fees, legal expenses and other costs and
                  expenses incurred by the Agent in connection with the collection
                  of the
                  Indebtedness and the enforcement of the Agent’s rights under this
                  Agreement and the Credit Agreement.  The Debtors shall, to the
                  extent permitted by applicable law, remain liable for any deficiency
                  if
                  the proceeds of any such sale or other disposition of the Collateral
                  (conducted in conformity with this clause (ii) and applicable law)
                  applied
                  to the Indebtedness are insufficient to pay the Indebtedness in
                  full
                  (other than contingent liabilities pursuant to any indemnity, including
                  without limitation Section
                  5.5 and Section
                  5.6 hereof, for claims which have not been asserted,
                  or which
                  have not yet accrued).  The Agent shall apply the proceeds from
                  the sale of the Collateral hereunder against the Indebtedness in
                  such
                  order and manner as provided in the Credit
                  Agreement.

                  any limitation or restriction with which compliance is necessary
                  (based on

                For
                  purposes of enabling the Agent to exercise its rights and remedies
                  under

                  termination of this Agreement in accordance with the provisions
                  of Section

                  license
                  (exercisable without payment of royalty or other compensation to
                  the
                  Debtors) to use, assign, license or sublicense any of the Intellectual

        6.2      Private Sales.

       

      
        	
                 

              	
                (a)

              	
                In
                  view of the fact that applicable securities laws may impose certain
                  restrictions on the method by which a sale of the Pledged Shares
                  may be
                  effected after an Event of Default, Debtors agree that upon the
                  occurrence
                  and during the continuance of an Event of Default, the Agent may
                  from time
                  to time attempt to sell all or any part of the Pledged Shares by
                  a private
                  sale in the nature of a private placement, restricting the bidders
                  and
                  prospective purchasers to those who will represent and agree that
                  they are
                  “accredited investors” within the meaning of Regulation D promulgated
                  pursuant to the Securities Act of 1933, as amended (the
                  “Securities Act”), and are purchasing for
                  investment only and not for distribution. In so doing, the Agent
                  may
                  solicit offers for the Pledged Shares, or any part thereof, from
                  a limited
                  number of investors who might be interested in purchasing the Pledged
                  Shares. Without limiting the methods or manner of disposition which
                  could
                  be determined to be commercially reasonable, if the Agent hires
                  a firm of
                  regional or national reputation that is engaged in the business
                  of
                  rendering investment banking and brokerage services to solicit
                  such offers
                  and facilitate the sale of the Pledged Shares, then the Agent’s acceptance
                  of the highest offer (including its own offer, or the offer of
                  any of the
                  Lenders at any such sale) obtained through such efforts of such
                  firm shall
                  be deemed to be a commercially reasonable method of disposition
                  of such
                  Pledged Shares.  The Agent shall not be under any obligation to
                  delay a sale of any of the Pledged Shares for the period of time
                  necessary
                  to permit the issuer of such securities to register such securities
                  under
                  the laws of any jurisdiction outside the United States, under the
                  Securities Act or under any applicable state securities laws, even
                  if such
                  issuer would agree to do so.

              

      

       

      
        	
                 

              	
                (b)

              	
                The
                  Debtors further agree to do or cause to be done, to the extent
                  that the
                  Debtors may do so under applicable law, all such other reasonable
                  acts and
                  things as may be reasonably necessary to make such sales or resales
                  of any
                  portion or all of the Collateral valid and binding and in compliance
                  with
                  any and all applicable laws, regulations, orders, writs, injunctions,
                  decrees or awards of any and all courts, arbitrators or governmental
                  instrumentalities, domestic or foreign, having jurisdiction over
                  any such
                  sale or sales, all at the Debtors’
expense.

        the occurrence of any Event of Default (as defined in the Credit Agreement),
        including without limit a breach of any of the provisions of this Agreement,

        shall
        have consented to such sale or disposition in accordance with the terms thereof,
        or (c) if such release has been approved by the requisite Lenders in accordance

      Section
        7.15    Consistent Application.  The

        the Indebtedness is from time to time temporarily reduced to zero) and the
        Agent’s security interest in the Collateral as granted herein shall continue in
        full force and effect for the entire duration that the Credit Agreement remains
        in effect and until all of the Indebtedness are repaid and discharged in
        full
        (other than contingent liabilities pursuant to any indemnity, including without
        limitation Section 5.5 and
Section 5.6 hereof,
        for claims which have not been
        asserted, or which have not yet accrued), and no commitment (whether optional
        or
        obligatory) to extend any credit under the Credit Agreement remain
        outstanding.

       

      Section
        7.17    Determination of Value of
        Collateral.

       

      The
        following shall be the basis of any finder of fact’s determination of the value
        of any Collateral which is the subject matter of a disposition giving rise
        to a
        calculation of any surplus or deficiency under Section 9.615(f) of the UCC:
        (a)
        the Collateral which is the subject matter of the disposition shall be valued
        in
        an “as is” condition as of the date of the disposition, without nay assumption
        or expectation that such Collateral will be repaired or improved in any matter;
        (b) the valuation shall be based upon an assumption that the transferee of
        such
        Collateral desires a resale of the Collateral for cash promptly (but no later
        than 30 days) following the disposition; (c) all reasonable closing costs
        customarily borne by the seller in commercial sales transactions relating
        to
        property similar to such Collateral shall be deducted, including, without
        limitation, brokerage commissions, tax prorations, attorneys’ fees, whether
        in-house or outside counsel is used, and marketing costs, (d) the value of
        the
        collateral which is the subject matter of the disposition shall be further
        discounted to account for any estimated holding costs associated with
        maintaining such Collateral pending sale (to the extent not accounted for
        in (c)
        above) and other maintenance, operational and ownership expenses and (e)
        any
        expert opinion testimony given or considered in connection with a determination
        of the value of such Collateral must be given by persons having at least
        5 years
        experience in appraising property similar to the Collateral and who have
        conducted and prepared a complete written appraisal of such Collateral taking
        into consideration the factors set forth above.  The “value” of any
        such Collateral shall be a factor in determining the amount of proceeds which
        would have been realized in a disposition to a transferee other than the
        Agent
        or a Lender, a Person related to the Agent or a Lender, or a secondary obligor
        under Section 9-615(f) of the UCC.

        be and become part of the Collateral referred to in the Security Agreement
        and

      This
        Amendment may be executed in any number of counterparts, each of which shall

        agrees that any copy of this Amendment signed by it and transmitted by facsimile

        (“Sterling”), and certain of its Subsidiaries
        (collectively, with Sterling, the “Borrowers”),
        the

      G.           This
        Joinder Agreement may be executed in any number of counterparts, each of
