      Exposure at any one time outstanding shall not exceed the lesser of (i) the
      LC
      Commitment or (ii) the Aggregate Revolving Credit Commitments, as then in
      effect, minus the aggregate principal amount of all Loans then outstanding.
      The
      Lenders shall participate in such Letters of Credit according to their
      respective Percentage Shares. Each of the Letters of Credit shall (i) be issued
      by the Issuing Bank, (ii) contain such terms and provisions as are reasonably
      required by the Issuing Bank, (iii) be for the account of such Obligor, and
      (iv)
      expire not later than the earlier of (A) twelve months from the date of issuance
      of such Letter of Credit and (B) five (5) Business Days before the Revolving

    (c)
      Limitation

      that,
      without
      the prior written consent of the Majority Lenders, no more than eight LIBOR
      Loans may be outstanding at any time.

      Continuations and Conversions, Letters of Credit.
       

     

    (a)
      Borrowings.
      The
      Borrower shall give the Administrative Agent (which shall promptly notify the
      Lenders) advance notice as hereinafter provided of each borrowing hereunder,
      which shall specify (i) the aggregate amount of such borrowing, (ii) the Type
      and (iii)
      the
      date (which shall be a Business Day) of the Loans to be borrowed, and (iv)
      (in
      the case of LIBOR Loans) the duration of the Interest Period therefor.
 

    15

     

    (b)
      Minimum
      Amounts.
      If a
      borrowing consists in whole or in part of LIBOR Loans, such LIBOR Loans shall
      be
      in amounts of at least $500,000 or any whole multiple of $250,000 in excess
      thereof. If a borrowing consists in whole or in part of Base Rate Loans, such
      Base Rate Loans shall be in amounts of at least $500,000 or integral multiples
      of $250,000 in excess thereof.  

     

    (c)
      Notices.
      All
      borrowings, continuations and conversions shall require advance written notice
      to the Administrative Agent (which shall promptly notify the Lenders) in the
      form of Exhibit
      B
      (or
      telephonic notice promptly confirmed by such a written notice), which in each
      case shall be irrevocable, from the Borrower to be received by the
      Administrative Agent not later than 12:00 p.m. Charlotte, North Carolina time
      at
      least one Business Day prior to the date of each Base Rate Loan borrowing and
      three Business Days prior to the date of each LIBOR Loan borrowing, continuation
      or conversion. Without in any way limiting the Borrower’s obligation to confirm
      in writing any telephonic notice, the Administrative Agent may act without
      liability upon the basis of telephonic notice believed by the Administrative
      Agent in good faith to be from the Borrower prior to receipt of written
      confirmation. In each such case, the Borrower hereby waives the right to dispute
      the Administrative Agent’s record of the terms of such telephonic notice except
      in the case of gross negligence or willful misconduct by the Administrative
      Agent.  

     

    (d)
      Continuation
      Options.

      2.02(d),

      expiration of the then current Interest Period relating thereto by giving
      advance notice as provided in Section
      2.02(c)
      to the
      Administrative Agent (which shall promptly notify the Lenders) of such election,
      specifying the amount of such Loan to be continued and the Interest Period
      therefor. In the absence of such a timely and proper election, the Borrower
      shall be deemed to have elected to convert such LIBOR Loan to a Base Rate Loan
      pursuant to Section
      2.02(e).
      All or
      any part of any LIBOR Loan may be continued as provided herein, provided that
      (i) any continuation of any such Loan shall be (as to each Loan as continued
      for
      an applicable Interest Period) in amounts of at least $500,000 or any whole
      multiple of $250,000 in excess thereof and (ii) no Default shall have occurred
      and be continuing. If a Default shall have occurred and be continuing, each
      LIBOR Loan shall be converted to a Base Rate Loan on the last day of the
      Interest Period applicable thereto.  

     

    (e)
      Conversion
      Options.
      The
      Borrower may elect to convert all or any part of any LIBOR Loan on the last
      day
      of the then current Interest Period relating thereto to a Base Rate Loan by
      giving advance notice to the Administrative Agent (which shall promptly notify
      the Lenders) of such election. Subject to the provisions made in this
Section
      2.02(e),
      the
      Borrower may elect to convert all or any part of any Base Rate Loan at any
      time
      and from time to time to a LIBOR Loan by giving advance notice as provided
      in
Section
      2.02(c)
      to the
      Administrative Agent (which shall promptly notify the Lenders) of such election.
      All or any part of any outstanding Loan may be converted as provided herein,
      provided that (i) any conversion of any Base Rate Loan into a LIBOR Loan shall
      be (as to each such Loan into which there is a conversion for an applicable
      Interest Period) in amounts of at least $500,000 or any whole multiple of
      $250,000 in excess thereof and (ii) no Default shall have occurred and be
      continuing. If a Default shall have occurred and be continuing, no Base Rate
      Loan may be converted into a LIBOR Loan.

    (g)
      Letters
      of Credit.
      The
      Borrower shall give the Issuing Bank (which shall promptly notify the Lenders
      of
      such request and their Percentage Share of such Letter of Credit) advance notice
      to be received by the Issuing Bank not later than 12:00 p.m. Charlotte, North
      Carolina time not less than three Business Days prior thereto of each request

      and conditions of this Agreement, on the date specified for the issuance,
      renewal or extension of a Letter of Credit, the Administrative Agent shall
      issue, renew or extend such Letter of Credit to the beneficiary thereof.
 

     

    In
      conjunction with the issuance of each Letter of Credit, the Borrower shall
      execute a Letter of Credit Agreement. In the event of any conflict between
      any
      provision of a Letter of Credit Agreement and this Agreement, the Borrower,
      the
      Issuing Bank, the Administrative Agent and the Lenders hereby agree that the
      provisions of this Agreement shall govern.  

     

    The
      Issuing Bank will send to the Borrower and each Lender, immediately upon
      issuance of any Letter of Credit, or an amendment thereto, a true and complete
      copy of such Letter of Credit, or such amendment thereto.  

     

    Section
      2.03 Commitments;
      Changes of Commitments.
       

     

    (a)
      Commitments.
      The
      initial amount of the Aggregate Revolving Credit Commitments shall be
      $155,000,000. The Aggregate Revolving Credit Commitments may be increased from
      time to time in accordance with subsection
      (b) of
      this
      section, or reduced from time to time in accordance with subsection
      (c)
      of this
      section.  

     

    (b)
      Increase
      in Revolving Credit Commitments.
       

     

    (i)
      Provided there exists no Default or Event of Default and subject to the
      conditions set forth under clause
      (v) below,
      upon notice to the Administrative Agent (which shall promptly notify the
      Lenders), Borrower may from time to time request an increase in the Revolving
      Credit Commitments; provided,
      that
      (A)
      the
      Aggregate Revolving Credit Commitments shall not at any time exceed the lesser
      of (1) the Aggregate Maximum Revolving Credit Amounts after adjustments
      resulting from reductions thereof pursuant to Section
      2.03(d)
      and (2)
      the then effective Borrowing Base, and (B) such increase of the Revolving Credit
      Commitments shall be in a minimum amount of $5,000,000, or integral multiples
      of
      $1,000,000 in excess thereof. At the time of sending such notice, Borrower
      (in
      consultation with the Administrative Agent) shall specify the time period within
      which each Lender is requested to respond (which shall in no event be less
      than
      ten (10) Business Days from the date of delivery of such notice to the Lenders).
       

     

    (ii)
      Each
      Lender shall notify the Administrative Agent within such time period whether
      or
      not it agrees to increase its Revolving Credit Commitment and, if so, whether
      by
      an amount equal to, greater than, or less than its Percentage Share of such
      requested increase. Any Lender not responding within such time period shall
      be
      deemed to have declined to increase its Revolving Credit Commitment.

    17

     

    (iii)
      The
      Administrative Agent shall notify Borrower of the Lenders’ responses to the
      request made hereunder. To achieve the full amount of a requested increase
      and
      subject to the approval of the Administrative Agent and the Issuing Bank (which
      approvals shall not be unreasonably withheld), Borrower may also invite
      additional Persons to become Lenders pursuant to a joinder agreement in form
      and
      substance satisfactory to the Administrative Agent and its counsel.  

     

    (iv)
      If
      the Aggregate Revolving Credit Commitments are increased in accordance with
      this
      Section, the Administrative Agent and Borrower shall determine the effective
      date (such date, the “Increase
      Effective Date”)
      and
      the final allocation of such increase. The Administrative Agent shall promptly
      (i) notify Borrower of the final allocation of such increase in the Revolving
      Credit Commitment and the Increase Effective Date, and (ii) notify each Lender
      of its Revolving Credit Commitment as of the Increase Effective Date.
 

     

    (v)
      As a
      condition precedent to such increase, Borrower shall deliver to the
      Administrative Agent a certificate of each Obligor dated as of the Increase
      Effective Date signed by a Responsible Officer of such Obligor (i) certifying
      and attaching the resolutions adopted by such Obligor approving or consenting
      to
      such increase, and (ii) in the case of Borrower, certifying that, before and
      after giving effect to such increase, (A) the representations and warranties
      contained in Article
      VII
      and the
      other Loan Documents are true and correct on and as of the Increase Effective
      Date, except to the extent that such representations and warranties specifically
      refer to an earlier date, in which case they are true and correct as of such
      earlier date, and except that for purposes of this Section
      2.03(b),
      the
      representations and warranties contained in Section
      7.02
      shall be
      deemed to refer to the most recent statements furnished pursuant to clauses
      (a)
      and
(b),
      respectively, of Section
      8.01,
      (B) no
      Default or Event of Default exists, and (C) no Material Adverse Effect shall
      have occurred. To the extent necessary to keep the outstanding Loans ratable
      with any revised Percentage Shares of the Lenders arising from any nonratable
      increase in the Revolving Credit Commitment under this Section, Borrower shall
      prepay Loans outstanding on the Increase Effective Date and/or Lenders shall
      make assignments pursuant to arrangements satisfactory to the Administrative
      Agent (provided,
      that
      in each
      case, Borrower shall pay any additional amounts required pursuant to
Section
      5.05).
      

     

     (vi)
      This
      Section shall supersede any provisions in Sections
      4.05
      or
12.04
      to the
      contrary.  

     

    (c)
      Reduction
      in Aggregate Revolving Credit Commitments.
      The
      Borrower shall have the right to reduce the amount of the Aggregate Revolving
      Credit Commitments at any time, or from time to time, upon not less than three
      (3) Business Days’ prior notice to the Administrative Agent (who shall promptly
      notify the Lenders) of each such reduction, which notice shall specify the
      effective date thereof and the amount of any such reduction (which shall not
      be
      less than $10,000,000 or any whole multiple of $10,000,000 in excess thereof;
      and no more than an amount by which the Aggregate Revolving Credit Commitments
      would be less than the aggregate outstanding principal amount of the Loans
      plus
      the LC Exposure, after giving effect to any concurrent prepayment pursuant
      to
Section
      2.07)
      and
      shall be irrevocable and effective only upon receipt by the Administrative
      Agent. 

     

     (d)
      Reduction
      in Aggregate Maximum Revolving Credit Amounts.
      The
      Borrower shall have the right to terminate or to reduce the amount of the
      Aggregate Maximum Revolving Credit Amounts at any time, or from time to time,
      upon not less than three (3) Business Days’ prior notice to the Administrative
      Agent (who shall promptly notify the Lenders) of each such termination or
      reduction, which notice shall specify the effective date thereof and the amount
      of any such reduction (which shall not be less than $10,000,000
      or any whole multiple of $10,000,000 in excess thereof; and no more than an
      amount by which the Aggregate Maximum Revolving Credit Amounts would be less
      than the Aggregate Revolving Credit Commitments) and shall be irrevocable and
      effective only upon receipt by the Administrative Agent. The Aggregate Maximum
      Revolving Credit Amounts once terminated or reduced may not be reinstated.

    Section
      2.04 Fees.
       

     

    (a)
      Commitment
      Fee.
      The
      Borrower shall pay to the Administrative Agent for the account of each Lender
      a
      commitment fee on the daily average unused amount of the Aggregate Revolving
      Credit Commitments up to, but excluding, the earlier of the date the Aggregate
      Revolving Credit Commitments are terminated or the Revolving Credit Termination
      Date at the Applicable Commitment Fee Rate. Accrued commitment fees shall be
      payable quarterly in arrears on each Quarterly Date and on the earlier of the
      date the Aggregate Revolving Credit Commitments are terminated or the Revolving
      Credit Termination Date. Borrower and Lenders acknowledge and agree that the
      unused commitment fees payable hereunder are bona
      fide
      unused
      commitment fees and are intended as reasonable compensation to Lenders for
      committing to make funds available to Borrower as described herein and for
      no
      other purposes. 

     

    (b)
      Letter
      of Credit Fees.
       

     

    (i)
      The
      Borrower agrees to pay the Administrative Agent, for the account of each Lender,
      commissions for issuing the Letters of Credit on the daily average outstanding
      of the maximum liability of the Issuing Bank existing from time to time under
      such Letter of Credit (calculated separately for each Letter of Credit) at
      the
      rate per annum equal to the Applicable Margin in effect from time to time for
      LIBOR Loans, provided that each Letter of Credit shall bear a minimum commission
      of $500 and further provided, during any period commencing on the date of an
      Event of Default until the same is paid in full or all Events of Default are
      cured and waived, equal to the Post-Default Rate. Each Letter of Credit shall
      be
      deemed to be outstanding up to the full face amount of the Letter of Credit
      until the Issuing Bank has received the canceled Letter of Credit or a written
      cancellation of the Letter of Credit from the beneficiary of such Letter of
      Credit in form and substance acceptable to the Issuing Bank, or for any
      reductions in the amount of the Letter of Credit (other than from a drawing),
      written notification from the beneficiary of such Letter of Credit. Such
      commissions are payable in advance at issuance of the Letter of Credit for
      the
      first year thereof and thereafter, quarterly in arrears on each Quarterly Date
      and upon cancellation or expiration of each such Letter of Credit.  

     

    (ii)
      The
      Borrower agrees to pay the Administrative Agent, for the account of the Issuing
      Bank, commissions for issuing the Letters of Credit (calculated separately
      for
      each Letter of Credit) equal to 0.125% of the face amount of each Letter of
      Credit, payable upon issuance of such Letter of Credit.  

     

    (c)
      Fee
      Letter.
      The
      Borrower shall pay to Administrative Agent for its account such other fees
      as
      are set forth in the Fee Letter on the dates specified therein to the extent
      not
      paid prior to the Closing Date.  

     

    Section
      2.05 Several
      Obligations.
      The
      failure of any Lender to make any Loan to be made by it or to provide funds
      for
      disbursements or reimbursements under Letters of Credit on the date specified
      therefor shall not relieve any other Lender of its obligation to make its Loan
      or provide funds on such date, but no Lender shall be responsible for the
      failure of any other Lender to make a Loan to be made by such other Lender
      or to
      provide funds to be provided by such other Lender.  

    19

    Section
      2.06 Notes.
      The
      Loans made by each Lender shall be evidenced by a single promissory note of
      the
      Borrower in substantially the form of Exhibit
      A
      dated
      (i) the Closing Date or (ii) the effective date of an Assignment pursuant to
      Section
      12.06(b),
      payable
      to the order of such Lender in a principal amount equal to its Maximum Revolving
      Credit Amount as originally in effect and otherwise duly completed and such
      substitute Notes as required by Section
      12.06(b).
      The
      date, amount, Type, interest rate and Interest Period of each Loan made by
      each
      Lender, and all payments made on account of the principal thereof, shall be
      recorded by such Lender on its books for its Note, and, prior to any transfer
      may be endorsed by such Lender on the schedule attached to such Note or any
      continuation thereof or on any separate record maintained by such Lender.
      Failure to make any such notation or to attach a schedule shall not affect
      any
      Lender’s or the Borrower’s rights or obligations in respect of such Loans or
      affect the validity of such transfer by any Lender of its Note.  

     

    Section
      2.07 Prepayments  

     

    (a)
      Voluntary
      Prepayments.
      The
      Borrower may prepay the Base Rate Loans upon not less than one (1) Business
      Day’s prior notice to the Administrative Agent (which shall promptly notify the
      Lenders), which notice shall specify the prepayment date (which shall be a
      Business Day) and the amount of the prepayment (which shall be at least $100,000
      or the remaining aggregate principal balance outstanding on the Notes) and
      shall
      be irrevocable and effective only upon receipt by the Administrative Agent,
      provided that interest on the principal prepaid, accrued to the prepayment
      date,
      shall be paid on the prepayment date. The Borrower may prepay LIBOR Loans on
      the
      same conditions as for Base Rate Loans (except that prior notice to the
      Administrative Agent shall be not less than three (3) Business Days for LIBOR
      Loans) and in addition such prepayments of LIBOR Loans shall be subject to
      the
      terms of Section
      5.05
      and
      shall be in an amount equal to all of the LIBOR Loans for the Interest Period
      prepaid. In the event of a voluntary prepayment pursuant to this Section
      2.07(a),
      Borrower shall be entitled to reborrow such amounts pursuant to Section
      2.01.
       

     

    (b)
      Mandatory
      Prepayments.
      If a
      Borrowing Base Deficiency results from the redetermination of the Borrowing
      Base
      pursuant to Section
      2.08(b) or
      (d),
      then
      the Borrower shall, within thirty (30) days notify Administrative Agent of
      Borrower’s election to, (i) prepay the Loans in two equal installments equal to
      one half of the aggregate principal amount sufficient to eliminate such
      Borrowing Base Deficiency, together with interest on the principal amount paid
      accrued to the date of each such prepayment due ninety (90) days and one hundred
      and eighty (180) days from the date of such redetermination, (ii) pledge, or
      cause any Subsidiary to pledge, additional unencumbered collateral of sufficient
      value and character (as determined by the Administrative Agent and the Lenders
      in their sole discretion) that when added to the existing collateral shall
      cause
      the Borrowing Base to equal or exceed the aggregate outstanding Loans plus
      the
      LC Exposure, or (iii) any combination of (i) and (ii) satisfactory to the
      Administrative Agent and all Lenders. If, because of LC Exposure, a Borrowing
      Base Deficiency remains after prepaying all of the Loans, the Borrower shall
      pay
      to the Administrative Agent on behalf of the Lenders an amount equal to such
      remaining Borrowing Base Deficiency to be held as cash collateral as provided
      in
Section
      2.10(b).
      

     

     (c)
      Generally.
      Prepayments permitted or required under this Section

      shall be
      without premium or penalty, except as required under Section
      5.05
      for
      prepayment of LIBOR Loans. Any prepayments on the Loans may be reborrowed
      subject to the then effective Aggregate Revolving Credit Commitments.
 

     

    Section
      2.08 Borrowing
      Base.
       

     

    (a)
      The
      Borrowing Base shall be determined in accordance with Section
      2.08(b)
      by the
      Administrative Agent with the concurrence of the Lenders and is subject to
      redetermination in accordance with Section
      2.08(d).
      Upon
      any redetermination of the Borrowing
      Base, such redetermination shall remain in effect until the next Redetermination
      Date. So long as any of the Commitments are in effect or any LC Exposure or
      Loans are outstanding hereunder, this facility shall be governed by the then
      effective Borrowing Base. During the period from and after the Closing Date
      until the first redetermination or reduction pursuant to Section
      2.08,
      the
      amount of the Borrowing Base shall be $155,000,000 (the “Initial
      Borrowing Base”)
      which
      amount is comprised of the Oil and Gas Properties Collateral Value.  

    20

     

    (b)
      Upon
      receipt of the reports required by Section
      8.07
      and such
      other reports, data and supplemental information as may from time to time be
      reasonably requested by the Administrative Agent (the “Engineering
      Reports”),
      the
      Borrowing Base shall be redetermined for each Borrowing Base Period and each
      such redetermination shall be effective as of the date set forth in such notice
      of redetermination delivered by the Administrative Agent to Borrower (the
“Scheduled
      Redetermination Date”).
      The
      Oil and Gas Properties Collateral Value shall be determined based upon the
      loan
      collateral value assigned to the Mortgaged Properties. The Borrowing Base shall
      be equal to the sum of the Oil and Gas Properties Collateral Value and such
      other credit factors (including without limitation the assets, liabilities,
      cash
      flow, business, properties, prospects, management and ownership of the Borrower
      and its Subsidiaries) which the Lenders deem significant. The Lenders’
determination of the Borrowing Base shall be in their sole discretion and shall
      not be subject to review or challenge. Upon each redetermination of the
      Borrowing Base, the Administrative Agent shall recommend to the Lenders a new
      Borrowing Base and the Lenders in accordance with their customary policies
      and
      procedures for extending credit to oil and gas reserve-based customers shall
      establish the redetermined Borrowing Base by unanimous agreement in the event
      of
      any increase in the Borrowing Base and by agreement of at least the Majority
      Lenders in the event of any redetermination to maintain or reduce the Borrowing
      Base. If a redetermined Borrowing Base is not approved by the Administrative
      Agent and the applicable Lenders within twenty (20) days of the submission
      to
      the Lenders by the Administrative Agent of its recommended Borrowing Base,
      the
      Administrative Agent shall notify each Lender that the recommended Borrowing
      Base has not been approved and request that each Lender submit to the
      Administrative Agent within ten (10) days thereafter its proposed Borrowing
      Base. Promptly following the 10th
      day
      after such request, the Administrative Agent shall determine the Borrowing
      Base
      for such Redetermination by calculating the highest Borrowing Base then
      acceptable to the Administrative Agent and a number of Lenders sufficient to
      constitute Majority Lenders (or all Lenders in the case of an increase). If
      the
      Borrower does not furnish the Engineering Reports by the date required, the
      Lenders may nonetheless determine a new Borrowing Base. It is expressly
      understood that the Lenders shall have no obligation to determine the Borrowing
      Base at any particular amount, either in relation to the Maximum Revolving
      Credit Amount or otherwise.  

     

    (c)
      The
      Borrower shall have the right to reduce the amount of the Borrowing Base upon
      not less than thirty (30) days’ prior written notice to the Administrative Agent
      (who shall promptly notify the Lenders) of the reduction, which shall specify
      the effective date thereof and the amount of such reduction (which shall not
      be
      less than $1,000,000 or any whole multiple of $1,000,000 in excess thereof,
      no
      more than an amount which would cause a Borrowing Base Deficiency) and shall
      be
      irrevocable and effective only upon receipt by the Administrative Agent. The
      Borrowing Base once reduced at Borrower’s election may not be reinstated by
      Borrower, nor shall Lenders be obligated to determine the Borrowing Base at
      any
      subsequent Scheduled Redetermination Date or other Special Borrowing Base
      Determination at any particular amount, either in relation to the Borrowing
      Base
      prior or subsequent to any such optional reduction by Borrower.  

     

    (d)
      In
      addition to “Scheduled
      Redeterminations”
      pursuant to Section
      2.08(b),
      the
      Borrower and the Majority Lenders may each request one (1) additional
      redetermination of the Borrowing Base during each Borrowing Base Period. In
      the
      event the Borrower or Majority Lenders request a “Special
      Borrowing Base Determination”
      pursuant to this Section
      2.08(d),
      the
      Borrower shall deliver written notice of such request to the Administrative
      Agent which shall include: (i) Engineering Report(s) prepared as of a date
      not more
      than
      thirty (30) calendar days prior to the date of such request, and (ii) such
      other
      information as Administrative Agent and the Lenders shall request prepared
      as of
      a date not more than thirty (30) calendar days prior to the date of such
      request. Likewise, in the event the Lenders exercise their option for a Special
      Borrowing Base Determination, the Administrative Agent shall give the Borrower
      notice of the redetermined Borrowing Base which shall state the effective date
      of the redetermination.  

    21

     

    Section
      2.09 Assumption
      of Risks.
      The
      Borrower assumes all risks of the acts or omissions of any beneficiary of any
      Letter of Credit or any transferee thereof with respect to its use of such
      Letter of Credit. Neither the Issuing Bank (except in the case of gross
      negligence or willful misconduct on the part of the Issuing Bank or any of
      its
      employees), its correspondents nor any Lender shall be responsible for the
      validity, sufficiency or genuineness of certificates or other documents or
      any
      endorsements thereon, even if such certificates or other documents should in
      fact prove to be invalid, insufficient, fraudulent or forged; for errors,
      omissions, interruptions or delays in transmissions or delivery of any messages
      by mail, telex, or otherwise, whether or not they be in code; for errors in
      translation or for errors in interpretation of technical terms; the validity
      or
      sufficiency of any instrument transferring or assigning or purporting to
      transfer or assign any Letter of Credit or the rights or benefits thereunder
      or
      proceeds thereof, in whole or in part, which may prove to be invalid or
      ineffective for any reason; the failure of any beneficiary or any transferee
      of
      any Letter of Credit to comply fully with conditions required in order to draw
      upon any Letter of Credit; or for any other consequences arising from causes
      beyond the Issuing Bank’s control or the control of the Issuing Bank’s
      correspondents. In addition, neither the Issuing Bank, the Administrative Agent
      nor any Lender shall be responsible for any error, neglect, or default of any
      of
      the Issuing Bank’s correspondents; and none of the above shall affect, impair or
      prevent the vesting of any of the Issuing Bank’s, the Administrative Agent’s or
      any Lender’s rights or powers hereunder or under the Letter of Credit
      Agreements, all of which rights shall be cumulative. The Issuing Bank and its
      correspondents may accept certificates or other documents that appear on their
      face to be in order, without responsibility for further investigation of any
      matter contained therein regardless of any notice or information to the
      contrary. In furtherance and not in limitation of the foregoing provisions,
      the
      Borrower agrees that any action, inaction or omission taken or not taken by
      the
      Issuing Bank or by any correspondent for the Issuing Bank in good faith in
      connection with any Letter of Credit, or any related drafts, certificates,
      documents or instruments, shall be binding on the Borrower and shall not put
      the
      Issuing Bank or its correspondents under any resulting liability to the
      Borrower.  

     

    Section
      2.10 Obligation
      to Reimburse and to Prepay.
       

     

    (a)
      If a
      disbursement by the Issuing Bank is made under any Letter of Credit, the
      Borrower shall pay to the Administrative Agent within two (2) Business Days
      after notice of any such disbursement is received by the Borrower, the amount
      of
      each such disbursement made by the Issuing Bank under the Letter of Credit
      (if
      such payment is not sooner effected as may be required under this Section
      2.10
      or under
      other provisions of the Letter of Credit), together with interest on the amount
      disbursed from and including the date of disbursement until payment in full
      of
      such disbursed amount at a varying rate per annum equal to (i) the then
      applicable interest rate for Base Rate Loans through the second Business Day
      after notice of such disbursement is received by the Borrower and (ii)
      thereafter, the Post-Default Rate for Base Rate Loans (but in no event to exceed
      the Highest Lawful Rate) for the period from and including the third Business
      Day following the date of such disbursement to and including the date of
      repayment in full of such disbursed amount. The obligations of the Borrower
      under this Agreement with respect to each Letter of Credit shall be absolute,
      unconditional and irrevocable and shall be paid or performed strictly in
      accordance with the terms of this Agreement under all circumstances whatsoever,
      including, without limitation, but only to the fullest extent permitted by
      applicable law, the following circumstances: (i) any lack of validity or
      enforceability of this Agreement, any Letter of Credit or any of the Security
      Instruments; (ii) any amendment or waiver of (including any default), or any
      consent to departure from this Agreement (except to the extent permitted by
      any
      amendment or waiver), any Letter of Credit or any of the Security Instruments;
      (iii) the existence of any claim, set-off,
      defense or other rights which the Borrower may have at any time against the
      beneficiary of any Letter of Credit or any transferee of any Letter of Credit
      (or any Persons for whom any such beneficiary or any such transferee may be
      acting), the Issuing Bank, the Administrative Agent, any Lender or any other
      Person, whether in connection with this Agreement, any Letter of Credit, the
      Security Instruments, the transactions contemplated hereby or any unrelated
      transaction; (iv) any statement, certificate, draft, notice or any other
      document presented under any Letter of Credit proves to have been forged,
      fraudulent, insufficient or invalid in any respect or any statement therein
      proves to have been untrue or inaccurate in any respect whatsoever; (v) payment
      by the Issuing Bank under any Letter of Credit against presentation of a draft
      certificate which appears on its face to comply, but does not comply, with
      the
      terms of such Letter of Credit; and (vi) any other circumstance or happening
      whatsoever, whether or not similar to any of the foregoing.  

    22

     

    Notwithstanding
      anything in this Agreement to the contrary, the Borrower will not be liable
      for
      payment or performance that results from the gross negligence or willful
      misconduct of the Issuing Bank, except (i) where the Borrower or any Subsidiary
      actually recovers the proceeds for itself or the Issuing Bank of any payment
      made by the Issuing Bank in connection with such gross negligence or willful
      misconduct or (ii) in cases where the Administrative Agent makes payment to
      the
      named beneficiary of a Letter of Credit.  

     

    (b)
      In
      the event of the occurrence of any Event of Default, a payment or prepayment
      pursuant to Section
      2.07(b) or
      the
      maturity of the Notes, whether by acceleration or otherwise, an amount equal
      to
      the LC Exposure (or the excess in the case of Section
      2.07(b))
      shall
      be deemed to be forthwith due and owing by the Borrower to the Issuing Bank,
      the
      Administrative Agent and the Lenders as of the date of any such occurrence;
      and
      the Borrower’s obligation to pay such amount shall be absolute and
      unconditional, without regard to whether any beneficiary of any such Letter
      of
      Credit has attempted to draw down all or a portion of such amount under the
      terms of a Letter of Credit, and, to the fullest extent permitted by applicable
      law, shall not be subject to any defense or be affected by a right of set-off,
      counterclaim or recoupment which the Borrower may now or hereafter have against
      any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders
      or
      any other Person for any reason whatsoever. Such payments shall be held by
      the
      Issuing Bank on behalf of the Lenders as cash collateral securing the LC
      Exposure in an account or accounts at the Principal Office; and the Borrower
      hereby grants to and by its deposit with the Administrative Agent grants to
      the
      Administrative Agent a security interest in such cash collateral. In the event
      of any such payment by the Borrower of amounts contingently owing under
      outstanding Letters of Credit and in the event that thereafter drafts or other
      demands for payment complying with the terms of such Letters of Credit are
      not
      made prior to the respective expiration dates thereof, the Administrative Agent
      agrees, if no Event of Default has occurred and is continuing or if no other
      amounts are outstanding under this Agreement, the Notes or the Security
      Instruments, to remit to the Borrower amounts for which the contingent
      obligations evidenced by the Letters of Credit have ceased.  

     

    (c)
      Each
      Lender severally and unconditionally agrees that it shall promptly reimburse
      the
      Issuing Bank an amount equal to such Lender’s Percentage Share of any
      disbursement made by the Issuing Bank under any Letter of Credit that is not
      reimbursed according to this Section
      2.10.
       

     

    (d)
      Notwithstanding anything to the contrary contained herein, if no Default exists
      and subject to availability under the Aggregate Revolving Credit Commitments
      (after reduction for LC Exposure), to the extent the Borrower has not reimbursed
      the Issuing Bank for any drawn upon Letter of Credit within one (1) Business
      Days after notice of such disbursement has been received by the Borrower, the
      amount of such Letter of Credit reimbursement obligation shall automatically
      be
      funded by the Lenders as a Loan
      hereunder
      and used
      by the Lenders to pay such Letter of Credit reimbursement obligation. If an
      Event of Default has occurred and is continuing, or if the funding of such
      Letter of Credit reimbursement obligation as a Loan would cause the aggregate
      amount of all Loans outstanding to exceed the Aggregate Revolving Credit
      Commitments (after reduction for LC Exposure), such Letter of Credit
      reimbursement obligation shall not be funded as a Loan, but instead shall accrue
      interest as provided in Section
      2.10(a).

    Section
      2.11 Lending

    (b)
      Generally.
      The

      The
      Borrower will pay to the Administrative Agent, for the account of each Lender,
      interest on the unpaid principal amount of each Loan made by such Lender for
      the
      period commencing on the date such Loan is made to, but excluding, the date
      such
      Loan shall be paid in full, at the following rates per annum:  

     

    (i)
      if
      such a Loan is a Base Rate Loan, the Base Rate (as in effect from time to time)
      plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate;
      and  

     

    (ii)
      if
      such a Loan is a LIBOR Loan, for each Interest Period relating thereto, the
      Adjusted LIBOR for such Loan plus the Applicable Margin (as in effect from
      time
      to time), but in no event to exceed the Highest Lawful Rate.  

     

    (b)
      Post-Default
      Rate.
      Notwithstanding the foregoing, the Borrower will pay to the Administrative
      Agent, for the account of each Lender interest at the applicable Post-Default
      Rate on any Loan made by such Lender, and (to the fullest extent permitted
      by
      law) on any other amount payable by the Borrower hereunder, under any Loan
      Document or under any Note held by such Lender to or for account of such Lender,
      for the period commencing on the date of an Event of Default until the same
      is
      paid in full or all Events of Default are cured or waived.  

     

    (c)
      Due
      Dates.
      Accrued
      interest on Base Rate Loans shall be payable on each Quarterly Date commencing
      on the first Quarterly Date, and accrued interest on each LIBOR Loan shall
      be
      payable on the last day of the Interest Period therefor and, if such Interest
      Period is longer than three months, at three-month intervals following the
      first
      day of such Interest Period, except that interest payable at the Post-Default
      Rate shall be payable from time to time on demand and interest on any LIBOR
      Loan
      that is converted into a Base Rate Loan (pursuant to Section
      5.04)
      shall
      be payable on the date of conversion (but only to the extent so converted).
      Any
      accrued and unpaid interest on the Loans on the Revolving Credit Termination
      Date shall be paid on such date.  

     

    (d)
      Determination
      of Rates.
      Promptly after the determination of any interest rate provided for herein or
      any
      change therein, the Administrative Agent shall notify the Lenders to which
      such
      interest is payable and the Borrower thereof. Each determination by
      the Administrative
      Agent of an interest rate or fee hereunder shall, except in cases of manifest
      error, be final, conclusive and binding on the parties.

      to the extent otherwise provided herein, all payments of principal, interest
      and
      other amounts to be made by the Borrower under this Agreement, the Notes,
      Letters of Credit, and the Letter of Credit Agreements shall be made in Dollars,
      in immediately available funds, to the Administrative Agent at such account
      as
      the Administrative Agent shall specify by notice to the Borrower from time
      to
      time, not later than 12:00 p.m. Charlotte, North Carolina time on the date
      on
      which such payments shall become due (each such payment made after such time
      on

      Day). Such payments shall be made without (to the fullest extent permitted
      by

      the
      Administrative Agent under this Agreement or any Note for account of a Lender
      shall be paid promptly to such Lender in immediately available funds. Except
      as
      otherwise provided in the definition of “Interest
      Period”,
      if the
      due date of any payment under this Agreement or any Note would otherwise fall
      on
      a day which is not a Business Day such date shall be extended to the next
      succeeding Business Day and interest shall be payable for any principal so
      extended for the period of such extension. At the time of each payment to the
      Administrative Agent of any principal of or interest on any borrowing, the
      Borrower shall notify the Administrative Agent of the Loans to which such
      payment shall apply. In the absence of such notice the Administrative Agent

      specify the Loans to which such payment shall apply, but to the extent possible
      such payment or prepayment will be applied first to the Loans comprised of
      Base

      borrowing from the Lenders under Section
      2.01 and
      each
      continuation and conversion under Section
      2.02
      shall be

      Borrower shall be made for account of the Lenders pro rata in accordance with
      the respective unpaid principal amount of the Loans held by the Lenders; and
      (iii) each payment of interest on Loans by the Borrower shall be made for
      account of the Lenders pro rata in accordance with the amounts of interest
      due
      and payable to the respective Lenders; and (iv) each reimbursement by the
      Borrower of disbursements under Letters of Credit shall be made for account
      of
      the Issuing Bank or, if funded by the Lenders, pro rata for the account of
      the
      Lenders, in accordance with the amounts of reimbursement obligations due and

      and
      actual days elapsed (including the first day but excluding the last day)
      occurring in the period for which such interest is payable, unless such
      calculation would exceed the Highest Lawful Rate, in which case interest shall
      be calculated on the per annum basis of a year of 365 or 366 days, as the case
      may be. Interest on Base Rate Loans shall be computed on the basis of a year
      of
      365 or 366 days, as the case may be, and actual days elapsed (including the
      first day but excluding the last day) occurring in the period for which such

      to
      the Administrative Agent (in
      the
      case of a Lender) of the proceeds of a Loan or a payment under a Letter of
      Credit to be made by it hereunder or (in the case of the Borrower) a payment
      to
      the Administrative Agent for account of one or more of the Lenders hereunder
      (such payment being herein called the “Required
      Payment”),
      which
      notice shall be effective upon receipt, that it does not intend to make the
      Required Payment to the Administrative Agent, the Administrative Agent may
      assume that the Required Payment has been made and may, in reliance upon such
      assumption (but shall not be required to), make the amount thereof available
      to
      the intended recipient(s) on such date and, if such Lender or the Borrower
      (as
      the case may be) has not in fact made the Required Payment to the Administrative
      Agent, the recipient(s) of such payment shall, on demand, repay to the
      Administrative Agent the amount so made available together with interest thereon
      in respect of each day during the period commencing on the date such amount
      was
      so made available by the Administrative Agent until, but excluding, the date
      the
      Administrative Agent recovers such amount at a rate per annum which, for any
      Lender as recipient, will be equal to the Federal Funds Rate, and for the
      Borrower as recipient, will be equal to the Base Rate plus the Applicable
      Margin.

    Section
      4.05 Set-off,
      Sharing of Payments, Etc.
       

     

    (a)
      The
      Borrower agrees that, in addition to (and without limitation of) any right
      of
      set-off, bankers’ lien or counterclaim a Lender may otherwise have, each Lender
      shall have the right and be entitled (after consultation with the Administrative
      Agent), at its option, to offset balances held by it or by any of its Affiliates
      for account of the Borrower or any Subsidiary at any of its offices, in Dollars
      or in any other currency, against any principal of or interest on any of such
      Lender’s Loans, or any other amount payable to such Lender hereunder, which is
      not paid when due (regardless of whether such balances are then due to the
      Borrower), in which case it shall promptly notify the Borrower and the
      Administrative Agent thereof, provided that such Lender’s failure to give such
      notice shall not affect the validity thereof.  

     

    (b)
      If
      any Lender shall obtain payment of any principal of or interest on any Loan
      made
      by it to the Borrower under this Agreement (or reimbursement as to any Letter
      of
      Credit) through the exercise of any right of set-off, banker’s lien or
      counterclaim or similar right or otherwise, and, as a result of such payment,
      such Lender shall have received a greater percentage of the principal or
      interest (or reimbursement) then due hereunder by the Borrower to such Lender
      than the percentage received by any other Lenders, it shall promptly (i) notify
      the Administrative Agent and each other Lender thereof and (ii) purchase from
      such other Lenders participations in (or, if and to the extent specified by
      such
      Lender, direct interests in) the Loans (or participations in Letters of Credit)
      made by such other Lenders (or in interest due thereon, as the case may be)
      in
      such amounts, and make such other adjustments from time to time as shall be
      equitable, to the end that all the Lenders shall share the benefit of such
      excess payment (net of any expenses which may be incurred by such Lender in
      obtaining or preserving such excess payment) pro rata in accordance with the
      unpaid principal and/or interest on the Loans held by each of the Lenders (or
      reimbursements of Letters of Credit). To such end all the Lenders shall make
      appropriate adjustments among themselves (by the resale of participations sold
      or otherwise) if such payment is rescinded or must otherwise be restored. The
      Borrower agrees that any Lender so purchasing a participation (or direct
      interest) in the Loans made by other Lenders (or in interest due thereon, as
      the
      case may be) may exercise all rights of set-off, banker’s lien, counterclaim or
      similar rights with respect to such participation as fully as if such Lender
      were a direct holder of Loans (or Letters of Credit) in the amount of such
      participation. Nothing contained herein shall require any Lender to exercise
      any
      such right or shall affect the right of any Lender to exercise, and retain
      the
      benefits of exercising, any such right with respect to any other indebtedness
      or
      obligation of the Borrower. If under any applicable bankruptcy, insolvency
      or
      other similar law, any Lender receives a secured claim in lieu of a set-off
      to
      which this Section
      4.05
      applies,
      such Lender shall, to the extent practicable, exercise its rights in
      respect of
      such
      secured claim in a manner consistent with the rights of the Lenders entitled
      under this Section
      4.05
      to share
      the benefits of any recovery on such secured claim.  

    26

     

    Section
      4.06 Taxes.
       

     

    (a)
      Payments
      Free and Clear.
      Any and
      all payments by the Borrower hereunder shall be made, in accordance with
Section
      4.01,
      free
      and clear of and without deduction for any and all present or future taxes,
      levies, imposts, deductions, charges or withholdings, and all liabilities with
      respect thereto, excluding,
      in the
      case of each Lender, the Issuing Bank and the Administrative Agent, taxes
      imposed on its income, and franchise or similar taxes imposed on it, by (i)
      any
      jurisdiction (or political subdivision thereof) of which the Administrative
      Agent, the Issuing Bank or such Lender, as the case may be, is a citizen or
      resident or in which such Lender has an Applicable Lending Office, (ii) the
      jurisdiction (or any political subdivision thereof) in which the Administrative
      Agent, the Issuing Bank or such Lender is organized, or (iii) any jurisdiction
      (or political subdivision thereof) in which such Lender, the Issuing Bank or
      the
      Administrative Agent is presently doing business which taxes are imposed solely
      as a result of doing business in such jurisdiction (all such non-excluded taxes,
      levies, imposts, deductions, charges, withholdings and liabilities being
      hereinafter referred to as “Taxes”).
      If
      the Borrower shall be required by law to deduct any Taxes from or in respect
      of
      any sum payable hereunder to the Lenders, the Issuing Bank or the Administrative
      Agent (i) the sum payable shall be increased by the amount necessary so that
      after making all required deductions (including deductions applicable to
      additional sums payable under this Section
      4.06)
      such
      Lender, the Issuing Bank or the Administrative Agent (as the case may be) shall
      receive an amount equal to the sum it would have received had no such deductions
      been made, (ii) the Borrower shall make such deductions and (iii) the Borrower
      shall pay the full amount deducted to the relevant taxing authority or other
      Governmental Authority in accordance with applicable law.  

     

    (b)
      Other
      Taxes.
      In
      addition, to the fullest extent permitted by applicable law, the Borrower agrees
      to pay any present or future stamp or documentary taxes or any other excise
      or
      property taxes, charges or similar levies that arise from any payment made
      hereunder or from the execution, delivery or registration of, or otherwise
      with
      respect to, this Agreement, any Assignment or any Security Instrument
      (hereinafter referred to as “Other
      Taxes”).
       

     

    (c)
      INDEMNIFICATION.
      TO THE
      FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER WILL INDEMNIFY EACH
      LENDER AND THE ISSUING BANK AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT
      OF
      TAXES AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY TAXES OR OTHER TAXES
      IMPOSED BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION
      4.06)
      PAID BY
      SUCH LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT (ON THEIR BEHALF
      OR ON
      BEHALF OF ANY LENDER), AS THE CASE MAY BE, AND ANY LIABILITY (INCLUDING
      PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM
      OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY
      OR LEGALLY ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR
      LEGALLY ASSERTED AND SUCH LENDER’S PAYMENT OF SUCH TAXES OR OTHER TAXES WAS THE
      RESULT OF ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. ANY PAYMENT PURSUANT
      TO
      SUCH INDEMNIFICATION SHALL BE MADE WITHIN THIRTY (30) DAYS AFTER THE DATE ANY
      LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT, AS THE CASE MAY BE, MAKES
      WRITTEN DEMAND THEREFOR. IF ANY LENDER, ISSUING BANK OR THE ADMINISTRATIVE
      AGENT
      RECEIVES A REFUND OR CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH
      SUCH LENDER, ISSUING BANK OR THE ADMINISTRATIVE AGENT HAS RECEIVED PAYMENT
      FROM
      THE BORROWER IT SHALL PROMPTLY NOTIFY THE BORROWER OF SUCH REFUND OR CREDIT
      AND
      SHALL, IF NO DEFAULT HAS OCCURRED AND IS CONTINUING, WITHIN THIRTY (30) DAYS
      AFTER RECEIPT OF A REQUEST BY THE
      BORROWER (OR PROMPTLY UPON RECEIPT, IF THE BORROWER HAS REQUESTED APPLICATION
      FOR SUCH REFUND OR CREDIT PURSUANT HERETO), PAY AN AMOUNT EQUAL TO SUCH REFUND
      OR CREDIT TO THE BORROWER WITHOUT INTEREST (BUT WITH ANY INTEREST SO REFUNDED
      OR
      CREDITED) PROVIDED THAT THE BORROWER, UPON THE REQUEST OF SUCH LENDER, THE
      ISSUING BANK OR THE ADMINISTRATIVE AGENT, AGREES TO RETURN SUCH REFUND OR CREDIT
      (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER OR THE ADMINISTRATIVE
      AGENT IN THE EVENT SUCH LENDER OR THE ADMINISTRATIVE AGENT IS REQUIRED TO REPAY
      SUCH REFUND OR CREDIT.  

    27

     

    (d)
      Lender
      Representations.
       

     

    (i)
      Each
      Lender represents that it is either (1) a banking association or corporation
      organized under the laws of the United States of America or any state thereof
      or
      (2) it is entitled to complete exemption from United States withholding tax
      imposed on or with respect to any payments, including fees, to be made to it
      pursuant to this Agreement (A) under an applicable provision of a tax convention
      to which the United States of America is a party or (B) because it is acting
      through a branch, agency or office in the United States of America and any
      payment to be received by it hereunder is effectively connected with a trade
      or
      business in the United States of America. Each Lender that is not a banking
      association or corporation organized under the laws of the United States of
      America or any state thereof agrees to provide to the Borrower and the
      Administrative Agent on the Closing Date, or on the date of its delivery of
      the
      Assignment pursuant to which it becomes a Lender, and at such other times as
      required by United States law or as the Borrower or the Administrative Agent
      shall reasonably request, two accurate and complete original signed copies
      of
      either (A) Internal Revenue Service Form W-8ECI (or successor form) certifying
      that all payments to be made to it hereunder will be effectively connected
      to a
      United States trade or business (the “Form
      W-8ECI Certification”)
      or (B)
      Internal Revenue Service Form W-8BEN (or successor form) certifying that it
      is
      entitled to the benefit of a provision of a tax convention to which the United
      States of America is a party which completely exempts from United States
      withholding tax all payments to be made to it hereunder (the “Form
      W-8BEN Certification”).
      In
      addition, each Lender agrees that if it previously filed a Form W-8ECI
      Certification, it will deliver to the Borrower and the Administrative Agent
      a
      new Form W-8ECI Certification prior to the first payment date occurring in
      each
      of its subsequent taxable years; and if it previously filed a Form W8BEN
      Certification, it will deliver to the Borrower and the Administrative Agent
      a
      new certification prior to the first payment date falling in the third year
      following the previous filing of such certification. Each Lender also agrees
      to
      deliver to the Borrower and the Administrative Agent such other or supplemental
      forms as may at any time be required as a result of changes in applicable law
      or
      regulation in order to confirm or maintain in effect its entitlement to
      exemption from United States withholding tax on any payments hereunder, provided
      that the circumstances of such Lender at the relevant time and applicable laws
      permit it to do so. If a Lender determines, as a result of any change in either
      (i) a Governmental Requirement or (ii) its circumstances, that it is unable
      to
      submit any form or certificate that it is obligated to submit pursuant to this
      Section
      4.06,
      or that
      it is required to withdraw or cancel any such form or certificate previously
      submitted, it shall promptly notify the Borrower and the Administrative Agent
      of
      such fact. If a Lender is organized under the laws of a jurisdiction outside
      the
      United States of America,
      unless the Borrower and the Administrative Agent have received a Form W-8BEN
      Certification or Form W-8ECI Certification satisfactory to them indicating
      that
      all payments to be made to such Lender hereunder are not subject to United
      States withholding tax, the Borrower shall withhold taxes from such payments
      at
      the applicable statutory rate. Each Lender agrees to indemnify and hold harmless
      the Borrower or Administrative Agent, as applicable, from any United States
      taxes, penalties, interest and other expenses, costs and losses incurred or
      payable by (i) the Administrative Agent as a result of such Lender’s failure to
      submit any form or certificate that it is required to provide pursuant to this
      Section
      4.06
      or (ii)
      the Borrower or the Administrative Agent as a result of their reliance on any
      such form or certificate which such Lender has provided to them pursuant to
      this
Section
      4.06.
       

    28

     

    (ii)
      For
      any period with respect to which a Lender has failed to provide the Borrower
      with the form required pursuant to this Section
      4.06,
      if any
      (other than if such failure is due to a change in a Governmental Requirement
      occurring subsequent to the date on which a form originally was required to
      be
      provided), such Lender shall not be entitled to indemnification under
Section
      4.06
      with
      respect to taxes imposed by the United States which taxes would not have been
      imposed but for such failure to provide such forms; provided, however, that
      if a
      Lender, which is otherwise exempt from or subject to a reduced rate of
      withholding tax, becomes subject to taxes because of its failure to deliver
      a
      form required hereunder, the Borrower shall take such steps as such Lender
      shall
      reasonably request to assist such Lender to recover such taxes.  

     

    (iii)
      Any
      Lender claiming any additional amounts payable pursuant to this Section
      4.06
      shall
      use reasonable efforts (consistent with legal and regulatory restrictions)
      to
      file any certificate or document requested by the Borrower or the Administrative
      Agent or to change the jurisdiction of its Applicable Lending Office or to
      contest any tax imposed if the making of such a filing or change or contesting
      such tax would avoid the need for or reduce the amount of any such additional
      amounts that may thereafter accrue and would not, in the sole determination
      of
      such Lender, be otherwise disadvantageous to such Lender.

    Section
      5.01 Additional
      Costs.  

     

    (a)
      LIBOR
      Regulations, etc.
      The
      Borrower shall pay directly to each Lender from time to time such amounts as
      such Lender may determine to be necessary to compensate such Lender for any
      costs which it determines are attributable to its making or maintaining of
      any
      LIBOR Loans or issuing or participating in Letters of Credit hereunder or its
      obligation to make any LIBOR Loans or issue or participate in any Letters of
      Credit hereunder, or any reduction in any amount receivable by such Lender
      hereunder in respect of any of such LIBOR Loans, Letters of Credit (such
      increases in costs and reductions in amounts receivable being herein called
      “Additional
      Costs”),
      resulting from any Regulatory Change which: (i) changes the basis of taxation
      of
      any amounts payable to such Lender under this Agreement or any Note in respect
      of any of such LIBOR Loans or Letters of Credit (other than taxes imposed on
      the
      overall net income of such Lender or of its Applicable Lending Office for any
      of
      such LIBOR Loans by the jurisdiction in which such Lender has its principal
      office or Applicable Lending Office); or (ii) imposes or modifies any reserve,
      special deposit, minimum capital, capital ratio or similar requirements relating
      to any extensions of credit or other assets of, or any deposits with or other
      liabilities of such Lender, or the Commitment or Loans of such Lender or the
      London interbank market; or (iii) imposes any other condition affecting this
      Agreement or any Note (or any of such extensions of credit or liabilities)
      or
      such Lender’s Commitment or Loans. Each Lender will notify the Administrative
      Agent and the Borrower of any event occurring after the Closing Date which
      will
      entitle such Lender to compensation pursuant to this Section
      5.01(a)
      as
      promptly as practicable after it obtains knowledge thereof and determines to
      request such compensation, and will designate a different Applicable Lending
      Office for the Loans of such Lender affected by such event if such designation
      will avoid the need for, or reduce the amount of, such compensation and will
      not, in the sole opinion of such Lender, be disadvantageous to such Lender,
      provided that such Lender shall have no obligation to so designate an
      Applicable Lending Office located in the United States. If any Lender requests
      compensation from the Borrower under this Section
      5.01(a),
      the
      Borrower may, by notice to such Lender, suspend the obligation of such Lender
      to
      make additional Loans of the Type with respect to which such compensation is
      requested until the Regulatory Change giving rise to such request ceases to
      be
      in effect (in which case the provisions of Section
      5.04
      shall be
      applicable). 

    29

     

     (b)
      Regulatory
      Change.
      Without
      limiting the effect of the provisions of Section
      5.01(a),
      in the
      event that at any time (by reason of any Regulatory Change or any other
      circumstances arising after the Closing Date affecting (A) any Lender, (B)
      the
      London interbank market or (C) such Lender’s position in such market), the
      Adjusted LIBOR, as determined in good faith by such Lender, will not adequately
      and fairly reflect the cost to such Lender of funding its LIBOR Loans, then,
      if
      such Lender so elects, by notice to the Borrower and the Administrative Agent,
      the obligation of such Lender to make additional LIBOR Loans shall be suspended
      until such Regulatory Change or other circumstances ceases to be in effect
      (in
      which case the provisions of Section
      5.04
      shall be
      applicable). 

     

     (c)
      Capital
      Adequacy.
      Without
      limiting the effect of the foregoing provisions of this Section
      5.01
      (but
      without duplication), the Borrower shall pay directly to any Lender from time
      to
      time on request such amounts as such Lender may reasonably determine to be
      necessary to compensate such Lender or its parent or holding company for any
      costs which it determines are attributable to the maintenance by such Lender
      or
      its parent or holding company (or any Applicable Lending Office), pursuant
      to
      any Governmental Requirement following any Regulatory Change, of capital in
      respect of its Commitment, its Note, or its Loans or any interest held by it
      in
      any Letter of Credit, such compensation to include, without limitation, an
      amount equal to any reduction of the rate of return on assets or equity of
      such
      Lender or its parent or holding company (or any Applicable Lending Office)
      to a
      level below that which such Lender or its parent or holding company (or any
      Applicable Lending Office) could have achieved but for such Governmental
      Requirement. Such Lender will notify the Borrower that it is entitled to
      compensation pursuant to this Section
      5.01(c)
      as
      promptly as practicable after it determines to request such compensation.
 

     

    (d)
      Compensation
      Procedure.
      Any
      Lender notifying the Borrower of the incurrence of Additional Costs under this
      Section
      5.01
      shall in
      such notice to the Borrower and the Administrative Agent set forth in reasonable
      detail the basis and amount of its request for compensation. Determinations
      and
      allocations by each Lender for purposes of this Section
      5.01
      of the
      effect of any Regulatory Change pursuant to Section
      5.01(a)
      or
(b),
      or of
      the effect of capital maintained pursuant to Section
      5.01(c),
      on its
      costs or rate of return of maintaining Loans or its obligation to make Loans
      or
      issue Letters of Credit, or on amounts receivable by it in respect of Loans
      or
      Letters of Credit, and of the amounts required to compensate such Lender under
      this Section
      5.01,
      shall
      be conclusive and binding for all purposes, provided that such determinations
      and allocations are made on a reasonable basis. Any request for additional
      compensation under this Section
      5.01
      shall be
      paid by the Borrower within thirty (30) days of the receipt by the Borrower
      of
      the notice described in this Section
      5.01(d).
       

     

    Section
      5.02 Limitation
      on LIBOR Loans.
      Anything herein to the contrary notwithstanding, if, on or prior to the
      determination of any Adjusted LIBOR for any Interest Period: 

     

     (i)
      the
      Administrative Agent determines (which determination shall be conclusive, absent
      manifest error) that quotations of interest rates for the relevant deposits
      referred to in the definition of “Adjusted
      LIBOR”
in
      Section
      1.02
      are not
      being provided in the relevant amounts or for the relevant maturities for
      purposes of determining rates of interest for LIBOR Loans as provided herein;
      or

    30

     

    (ii)
      the
      Administrative Agent determines (which determination shall be conclusive, absent
      manifest error) that the relevant rates of interest referred to in the
      definition of “Adjusted
      LIBOR”
in
      Section
      1.02
      upon the
      basis of which the rate of interest for LIBOR Loans for such Interest Period
      is
      to be determined are not sufficient to adequately cover the cost to the Lenders
      of making or maintaining LIBOR Loans; then the Administrative Agent shall give
      the Borrower prompt notice thereof, and so long as such condition remains in
      effect, the Lenders shall be under no obligation to make additional LIBOR Loans.
       

     

    Section
      5.03 Illegality.
      Notwithstanding any other provision of this Agreement, in the event that it
      becomes unlawful for any Lender or its Applicable Lending Office to honor its
      obligation to make or maintain LIBOR Loans hereunder, then such Lender shall
      promptly notify the Borrower thereof and such Lender’s obligation to make LIBOR
      Loans shall be suspended until such time as such Lender may again make and
      maintain LIBOR Loans (in which case the provisions of Section
      5.04
      shall be
      applicable).  

     

    Section
      5.04 Base
      Rate Loans Pursuant to Sections 5.01, 5.02 and 5.03.
      If the
      obligation of any Lender to make LIBOR Loans shall be suspended pursuant to
      Sections
      5.01,
      5.02
      or
5.03
      (“Affected
      Loans”),
      all
      Affected Loans which would otherwise be made by such Lender shall be made
      instead as Base Rate Loans (and, if an event referred to in Section
      5.01(b)
      or
Section
      5.03
      has
      occurred and such Lender so requests by notice to the Borrower, all Affected
      Loans of such Lender then outstanding shall be automatically converted into
      Base
      Rate Loans on the date specified by such Lender in such notice) and, to the
      extent that Affected Loans are so made as (or converted into) Base Rate Loans,
      all payments of principal which would otherwise be applied to such Lender’s
      Affected Loans shall be applied instead to its Base Rate Loans.  

     

    Section
      5.05 Compensation.
      The
      Borrower shall pay to each Lender within thirty (30) days of receipt of written
      request of such Lender (which request shall set forth, in reasonable detail,
      the
      basis for requesting such amounts and which shall be conclusive and binding
      for
      all purposes provided that such determinations are made on a reasonable basis),
      such amount or amounts as shall compensate it for any loss, cost, expense or
      liability which such Lender determines are attributable to: 

     

     (i)
      any
      payment, prepayment or conversion of a LIBOR Loan properly made by such Lender
      or the Borrower for any reason (including, without limitation, the acceleration
      of the Loans pursuant to Section
      10.01)
      on a
      date other than the last day of the Interest Period for such Loan; or

     

     (ii)
      any
      failure by the Borrower for any reason (including but not limited to, the
      failure of any of the conditions precedent specified in Article
      VI
      to be
      satisfied) to borrow, continue or convert a LIBOR Loan from such Lender on
      the
      date for such borrowing, continuation or conversion specified in the relevant
      notice given pursuant to Section
      2.02(c).

     

    Without
      limiting the effect of the preceding sentence, such compensation shall include
      an amount equal to the excess, if any, of (i) the amount of interest which
      would
      have accrued on the principal amount so paid, prepaid or converted or not
      borrowed for the period from the date of such payment, prepayment or conversion
      or failure to borrow to the last day of the Interest Period for such Loan (or,
      in the case of a failure to borrow, the Interest Period for such Loan which
      would have commenced on the date specified for such borrowing) at the applicable
      rate of interest for such Loan provided for herein over (ii) the interest
      component of the amount such Lender would have bid in the London interbank
      market for Dollar deposits of leading banks in amounts comparable to such
      principal amount and with maturities comparable to such period (as reasonably
      determined by such Lender).

    (c)
      the

      VII
      and in
      the Security Instruments shall be true on and as of the date of the making
      of
      such Loans or issuance, renewal, extension or reissuance of a Letter of Credit
      with the same force and effect as if made on and as of such date and following
      such new borrowing, except to the extent such representations and warranties
      are
      expressly limited to an earlier date.  

     

    Each
      request for a borrowing or issuance, renewal, extension or reissuance of a
      Letter of Credit by the Borrower hereunder shall constitute a certification
      by
      the Borrower to the effect set forth in Section

      (both as

      imposed hereby solely for the benefit of the Lenders, and no other Person may
      require satisfaction of any such condition precedent or be entitled to assume
      that the Lenders will refuse to make any Loan in the absence of strict
      compliance with such conditions precedent.  

     

    Section
      6.04 No
      Waiver.
      No
      waiver of any condition precedent shall preclude the Administrative Agent or
      the
      Lenders from requiring such condition to be met prior to making any subsequent
      Loan or preclude the Lenders from thereafter declaring that the failure of
      the
      Borrower to satisfy such condition precedent constitutes a Default.

    Representations
      and Warranties

     

    Each
      of
      the Obligors represents and warrants to the Administrative Agent and the Lenders
      that (each representation and warranty herein is given as of the Closing Date

      Existence.
      Each of
      the Obligors: (i) is a corporation, or limited partnership or limited liability
      company duly organized, formed, legally existing and in good standing under
      the
      laws of the jurisdiction of its incorporation or formation, as applicable;
      (ii)
      has all requisite corporate, partnership, or limited liability company power,

      or as proposed to be conducted; and (iii) is qualified to do business in all
      jurisdictions in which the nature of the business conducted by it makes such
      qualification necessary and where failure so to qualify would have a Material
      Adverse Effect.  

     

    Section
      7.02 Financial
      Condition.
      The
      Financial Statements are complete and correct and fairly present the
      consolidated financial condition of the AER and its Consolidated Subsidiaries

      of the applicable dates and the results of its operations for the applicable
      period, all in accordance with GAAP, as applied on a consistent basis (subject,

      Operations, to the matters described in the Registration Statement under the
      heading, “Management’s Discussion and Analysis of Financial Condition and

      the
      Obligors threatened against or affecting the Obligors or any Subsidiary which
      involves the possibility of any judgment or liability against any Obligor or
      any
      Subsidiary not fully covered by insurance (except for normal deductibles),
      and
      which would have a Material Adverse Effect. Schedule
      7.03 attached
      hereto is a list of all litigation in which any Obligor is a party under which
      the amount in controversy including all expenses, fees and costs is greater
      than
      $250,000.

     

    Section
      7.04 No
      Breach.
      Neither
      the execution and delivery of the Loan Documents, nor compliance with the terms
      and provisions hereof will conflict with or result in a breach of, or require
      any consent which has not been obtained as of the Closing Date under, the
      respective charter or by-laws of the Obligors, or any Governmental Requirement,
      or any agreement or instrument to which any Obligor is a party or by which
      it is
      bound or to which it or its Properties are subject, or constitute a default
      under any such agreement or instrument, or result in the creation or imposition
      of any Lien upon any of the revenues or assets of the Obligor pursuant to the
      terms of any such agreement or instrument other than the Liens created by the
      Loan Documents.

      7.05 Authority.
      Each
      Obligor has all necessary corporate, limited liability company, or partnership
      power and authority, as applicable, to execute, deliver and perform its
      obligations under the Loan Documents to which it is a party; and the execution,
      delivery and performance by each Obligor of the Loan Documents to which it
      is a
      party, have been duly authorized by all necessary corporate, limited liability
      company, or partnership action, as applicable, on its part; and the Loan
      Documents constitute the legal, valid and binding obligations of each Obligor,
      enforceable in accordance with their terms.  

     

    Section
      7.06 Approvals.
      No
      authorizations, approvals or consents of, and no filings or registrations with,
      any Governmental Authority or any other Person are necessary for the execution,
      delivery or performance by any Obligor of the Loan Documents to which it is
      a
      party or for the validity or enforceability thereof, except for the recording
      and filing of the Security Instruments as required by this Agreement.
 

     

    Section
      7.07 Use
      of Loans.
      The
      proceeds of the Loans shall be used (i) to repay on the Closing Date advances
      from AAI relating to the AAI Credit Agreement, (ii) for the development of
      the
      Obligors’ Oil and Gas Properties and the acquisition of Oil and Gas Properties

      contributions under the Partnerships, provided such capital contributions may

      working capital, (v) for Letters of Credit to support the obligations of the
      Borrower and its Subsidiaries, and (vi) for general company purposes of the
      Borrower and its Subsidiaries. Neither the Borrower nor any other Obligor is
      engaged principally, or as one of its important activities, in the business
      of
      extending credit for the purpose, whether immediate, incidental or ultimate,
      of
      buying or carrying margin stock (within the meaning of Regulation T, U or X
      of
      the Board of Governors of the Federal Reserve System) and no part of the
      proceeds of any Loan hereunder will be used to buy or carry any margin stock.
       

     

    Section
      7.08 ERISA.

     

    (a)
      Each

      respects with ERISA and, where applicable, the Code regarding each Plan.
 

     

    (b)
      Each
      Plan is, and has been, maintained in substantial compliance with ERISA and,
      where applicable, the Code.  

    35

    (c)
      No
      act, omission or transaction has occurred which could result in imposition
      on
      any Obligor, any Subsidiary or any ERISA Affiliate (whether directly or
      indirectly) of (i) either a civil penalty assessed pursuant to section 502(c),
      (i) or (1) of ERISA or a tax imposed pursuant to Chapter 43 of Subtitle D of
      the
      Code or (ii) breach of fiduciary duty liability damages under section 409 of
      ERISA.

     

    (d)
      No
      contingent obligations remain due to the termination of any Plan (other than
      a
      defined contribution plan) or any trust created under any such Plan since
      September 2, 1974. The only Plan that has been terminated was for The Atlas
      Group, Inc. No liability to the PBGC (other than for the payment of current
      premiums which are not past due) by any Obligor, any Subsidiary or any ERISA
      Affiliate has been or is expected by any Obligor, any Subsidiary or any ERISA
      Affiliate to be incurred with respect to any Plan. No ERISA Event with respect
      to any Plan has occurred.  

     

    (e)
      Full
      payment when due has been made of all amounts which any Obligor, any Subsidiary
      or any ERISA Affiliate is required under the terms of each Plan or applicable
      law to have paid as contributions to such Plan, and no accumulated funding
      deficiency (as defined in section 302 of ERISA and section 412 of the Code),
      whether or not waived, exists with respect to any Plan.  

     

    (f)
      The
      actuarial present value of the benefit liabilities under each Plan which is
      subject to Title IV of ERISA does not, as of the end of each Obligor’s most
      recently ended fiscal year, exceed the current value of the assets (computed
      on
      a plan termination basis in accordance with Title IV of ERISA) of such Plan
      allocable to such benefit liabilities. The term “actuarial
      present value of the benefit liabilities”
shall
      have the meaning specified in section 4041 of ERISA.

     

    (g)
      None
      of the Obligors, any Subsidiary or any ERISA Affiliate sponsors, maintains,
      or
      contributes to an employee welfare benefit plan, as defined in section 3(l)
      of
      ERISA, including, without limitation, any such plan maintained to provide
      benefits to former employees of such entities, that may not be terminated by
      an
      Obligor, a Subsidiary or any ERISA Affiliate in its sole discretion at any
      time
      without any material liability.  

     

    (h)
      None
      of the Obligors, any Subsidiary or any ERISA Affiliate sponsors, maintains
      or
      contributes to, or has at any time in the preceding six calendar years,
      sponsored, maintained or contributed to, any Multiemployer Plan.  

     

    (i)
      None
      of the Obligors, any Subsidiary or any ERISA Affiliate is required to provide
      security under section 401 (a)(29) of the Code due to a Plan amendment that
      results in an increase in current liability for the Plan.  

     

    Section
      7.09 Taxes.
      Each
      Obligor and its Subsidiaries has filed all United States federal income tax
      returns and all other tax returns which are required to be filed by them, or
      otherwise obtained appropriate extensions to file, and have paid all material
      taxes due pursuant to such returns or pursuant to any assessment received by
      any
      Obligor or any Subsidiary except such taxes that are being contested in good
      faith by appropriate proceedings and for which such Obligor, as applicable,
      has
      set aside on its books adequate reserves in accordance with GAAP. The charges,
      accruals and reserves on the books of each Obligor and its Subsidiaries in
      respect of taxes and other governmental charges are, in the opinion of the
      Borrower, adequate. No tax lien has been filed and, to the knowledge of the
      Obligors, no claim is being asserted with respect to any such tax, fee or other
      charge.  

     

    Section
      7.10 Titles,
      etc.  

     

    (a)
      Each
      of the Obligors has good and marketable title to its Oil and Gas Properties,
      free and clear of all Liens, except Excepted Liens. After giving full effect
      to
      the Excepted Liens, each Obligor owns either directly in its own name, or
      indirectly through its percentage
      ownership interest in the Partnerships, the net interests in production
      attributable to its Hydrocarbon Interests reflected in the most recently
      delivered Ownership Report and the ownership of such Oil and Gas Properties
      shall not in any material respect obligate such Obligor to bear the costs and
      expenses relating to the maintenance, development and operations of each such
      Oil and Gas Property in an amount in excess of the working interest of each
      Oil
      and Gas Property set forth in the most recently delivered Reserve Report;
      provided that to the extent an Obligor is a general partner of a Partnership,
      such Obligor is liable for all of the costs and expenses attributable to such
      Partnership’s interest, but only entitled to such Obligor’s percentage interest
      in such Partnership’s net revenues. In the event an Obligor, as a general
      partner, pays more than its partnership share of such Partnership’s costs and
      expenses, such Obligor is entitled to reimbursement of such excess amount out
      of
      the future income of such Partnership. All information contained in the most
      recently delivered Ownership Report and Reserve Report is true and correct
      in
      all material respects as of the date thereof.  

36

     

    (b)
      All
      leases and agreements necessary for the conduct of the business of the Obligors
      are valid and subsisting, in full force and effect and there exists no default
      or event or circumstance which with the giving of notice or the passage of
      time
      or both would give rise to a default under any such lease or leases, which
      would
      affect in any material respect the conduct of the business of any Obligor.
       

     

    (c)
      The
      rights, Properties and other assets presently owned, leased or licensed by
      the
      Obligors including, without limitation, all easements and rights of way, include
      all rights, Properties and other assets necessary to permit each Obligor to
      conduct its business in all material respects in the same manner as its business
      has been conducted prior to the Closing Date.  

     

    (d)
      All
      of the assets and Properties of any Obligor which are reasonably necessary
      for
      the operation of its business are in good working condition and are maintained
      in accordance with prudent business standards.  

     

    Section
      7.11 No
      Material Misstatements.
      No
      written information, statement, exhibit, certificate, document or report
      furnished to the Administrative Agent and the Lenders (or any of them) by any
      Obligor in connection with the negotiation of this Agreement contained any
      material misstatement of fact or omitted to state a material fact or any fact
      necessary to make the statement contained therein not materially misleading
      in
      the light of the circumstances in which made; provided
      that,
      with
      respect to financial projections concerning the Borrower and its Subsidiaries,
      the Borrower represents only that such information was prepared in good faith
      based on assumptions believed to be reasonable at the time. There is no fact
      peculiar to any Obligor which has a Material Adverse Effect or in the future
      is
      reasonably likely to have a Material Adverse Effect and which has not been
      set
      forth in this Agreement or the other documents, certificates and statements
      furnished to the Administrative Agent by or on behalf of the Obligors prior
      to,
      or on, the Closing Date in connection with the transactions contemplated hereby.
       

     

    Section
      7.12 Investment
      Company Act.
      None of
      the Obligors nor any Subsidiary is an “investment
      company”
or
      a
      company “controlled”
by
      an
“investment
      company,”
within
      the meaning of the Investment Company Act of 1940, as amended.

      the
      Partnerships set forth on Schedule

      None of
      the Obligors own any interest in any partnership or other Special Entity other
      than the Special Entities listed on Schedule
      7.15
      and the
      Partnerships. The Obligors’ ownership interests in the Partnerships are free and
      clear of any and all liens, claims and encumbrances including any preferential
      rights to purchase and consents to assignments.  

    37

      amount and type of the authorized securities of each of the entities listed
      on

      outstanding have been validly issued and are fully paid and nonassessable and

      7.15.
      Except

      7.15,
      neither
      Borrower nor any Guarantor owns directly or indirectly any capital stock of
      any
      other Person other than the Partnerships. Borrower and each Guarantor has good
      and marketable title to all the securities of the Subsidiaries (except for
      the
      Unrestricted Entities) issued to it, free and clear of all liens and
      encumbrances, and all such securities have been duly and validly issued and
      are
      fully paid and nonassessable.

    Section
      7.17 Defaults.
      None of
      the Obligors is in default nor has any event or circumstance occurred which,
      but
      for the expiration of any applicable grace period or the giving of notice,
      or
      both, would constitute a default under any Material Agreement or instrument
      to
      which any Obligor is a party or by which any Obligor is bound. No Default
      hereunder has occurred and is continuing.  

     

    Section
      7.18 Environmental
      Matters.
      Except
      as would not have a Material Adverse Effect (or with respect to (c),
      (d)
      and
(e)
      below,
      where the failure to take such actions would not have a Material Adverse
      Effect):

     

    (a)
      Neither any Property of Borrower or any Subsidiary nor the operations conducted
      thereon violate any order or requirement of any court or Governmental Authority
      or any Environmental Laws;

     

    (b)
      Without limitation of clause
      (a)
      above,
      no Property of Borrower or any Subsidiary nor the operations currently conducted
      thereon or, to the best knowledge of the Obligors, by any prior owner or
      operator of such Property or operation, are in violation of or Subject to any
      existing, pending or threatened action, suit, investigation, inquiry or
      proceeding by or before any court or Governmental Authority or to any remedial
      obligations under Environmental Laws;

     

    (c)
      All
      notices, permits, licenses or similar authorizations, if any, required to be
      obtained or filed in connection with the operation or use of any and all
      Property of Borrower and each Subsidiary, including without limitation past
      or
      present treatment, storage, disposal or release of a hazardous substance or
      solid waste into the environment, have been duly obtained or filed, and Borrower
      and each Subsidiary are in compliance with the terms and conditions of all
      such
      notices, permits, licenses and similar authorizations;

     

    (d)
      All
      hazardous substances, solid waste, and oil and gas exploration and production
      wastes, if any, generated at any and all Property of Borrower or any Subsidiary
      have in the past been transported, treated and disposed of in accordance with
      Environmental Laws and so as not to pose an imminent and substantial
      endangerment to public health or welfare or the environment, and, to the best
      knowledge of the Obligors, all such transport carriers and treatment and
      disposal facilities have been and are operating in compliance with Environmental
      Laws and so as not to pose an imminent and substantial endangerment to public
      health or welfare or the environment, and are not the subject of any existing,
      pending or threatened action, investigation or inquiry by any Governmental
      Authority in connection with any Environmental Laws;

     

    (e)
      Borrower has taken all steps reasonably necessary to determine and have
      determined that no hazardous substances, solid waste, or oil and gas exploration
      and production wastes, have been disposed of or otherwise released and there
      has
      been no threatened release
      of any hazardous substances on or to any Property of Borrower or any Subsidiary
      except in compliance with Environmental Laws and so as not to pose an imminent
      and substantial endangerment to public health or welfare or the
      environment;

    38

     

    (f)
      To
      the extent applicable, all Property of Borrower and each Subsidiary currently
      satisfies all design, operation, and equipment requirements imposed by the
      OPA
      or scheduled as of the Closing Date to be imposed by OPA during the term of
      this
      Agreement, and Borrower does not have any reason to believe that such Property,
      to the extent subject to OPA, will not be able to maintain compliance with
      the
      OPA requirements during the term of this Agreement; and

     

    (g)
      Neither Borrower nor any Subsidiary has any known contingent liability in
      connection with any release or threatened release of any oil, hazardous
      substance or solid waste into the environment.  

     

    Section
      7.19 Compliance
      with the Law.
      None of
      the Obligors has violated any Governmental Requirement or failed to obtain
      any
      license, permit, franchise or other governmental authorization necessary for
      the
      ownership of any of its Properties or the conduct of its business, which
      violation or failure would have (in the event such violation or failure were
      asserted by any Person through appropriate action) a Material Adverse Effect.
      Except for such acts or failures to act as would not have a Material Adverse
      Effect, the Oil and Gas Properties of the Obligors (and properties unitized
      therewith) have been maintained, operated and developed in a good and
      workmanlike manner and in conformity with all applicable laws and all rules,
      regulations and orders of all duly constituted authorities having jurisdiction
      and in conformity with the provisions of all leases, subleases or other
      contracts comprising a part of the Hydrocarbon Interests and other contracts
      and
      agreements forming a part of such Oil and Gas Properties; specifically in this
      connection, (i) after the Closing Date, no Oil and Gas Property of any Obligor
      is subject to having allowable production reduced below the full and regular
      allowable (including the maximum permissible tolerance) because of any
      overproduction (whether or not the same was permissible at the time) prior
      to
      the Closing Date and (ii) none of the wells comprising a part of the Oil and
      Gas
      Properties of any Obligor (or properties unitized therewith) are deviated from
      the vertical more than the maximum permitted by applicable laws, regulations,
      rules and orders, and such wells are, in fact, bottomed under and are producing
      from, and the well bores are wholly within, such Oil and Gas Properties (or
      in
      the case of wells located on properties unitized therewith, such unitized
      properties).  

     

    Section
      7.20 Insurance.
      Schedule
      7.20
      attached
      hereto contains an accurate and complete description of all material policies
      of
      fire, liability, workers’ compensation and other forms of insurance owned or
      held by the Obligors. All such policies are in full force and effect, all
      premiums with respect thereto covering all periods up to and including the
      date
      of the closing have been paid, and no notice of cancellation or termination
      has
      been received with respect to any such policy. Such policies are sufficient
      for
      compliance with all requirements of law and of all agreements to which any
      Obligor is a party; are valid, outstanding and enforceable policies; provide
      adequate insurance coverage in at least such amounts and against at least such
      risks (but including in any event public liability) as are usually insured
      against in the same general area by companies engaged in the same or a similar
      business for the assets and operations of the Obligors; will remain in full
      force and effect through the respective dates set forth in Schedule
      7.20
      without
      the payment of additional premiums; and will not in any way be affected by,
      or
      terminate or lapse by reason of, the transactions contemplated by this
      Agreement. Schedule
      7.20
      identifies all material risks, if any, which each Obligor and their respective
      Board of Directors or officers have designated as being self insured. None
      of
      the Obligors has been refused any insurance with respect to its assets or
      operations, nor has its coverage been limited below usual and customary policy
      limits, by an insurance carrier to which it has applied for any such insurance
      or with which it has carried insurance during the last three years.  

     

    Section
      7.21 Hedging
      Agreements.
      Schedule
      7.21
      sets
      forth, as of the Closing Date, a true and complete list of all Hedging
      Agreements (including commodity price swap agreements, forward agreements or
      contracts of sale which provide for prepayment for
      deferred shipment or delivery of oil, gas or other commodities) of the Obligors,
      the material terms thereof (including the type, term, effective date,
      termination date and notional amounts or volumes), the net mark to market value
      thereof, all credit support agreements relating thereto (including any margin
      required or supplied), and the counter party to each such agreement. Borrower
      is
      the only Person authorized to enter into Hedging Agreements on behalf of the
      Obligors and the Partnerships, and no other Obligor or Partnership currently
      does (or will in the future) enter into any Hedging Agreement on its own behalf.
       

    39

     

    Section
      7.22 Restriction
      on Liens.
      Neither
      the Borrower nor any Guarantor is a party to any agreement or arrangement (other
      than this Agreement and the Security Instruments), or subject to any order,
      judgment, writ or decree, which either restricts or purports to restrict its
      ability to grant Liens to other Persons on or in respect of their respective
      assets or Properties.  

     

    Section
      7.23 Material
      Agreements.
      Set
      forth on Schedule
      7.23 is
      a
      complete list of all agreements, indentures, purchase agreements, obligations
      in
      respect of letters of credit, guarantees, partnership agreements, exploration
      and development agreements, joint venture agreements, and other instruments
      which are material to each Obligor’s business, activities, and operation or
      ownership of such Obligors’ Property (the “Material
      Agreements”)
      in
      effect or to be in effect as of the Closing Date (other than the Partnership
      Agreements set forth on Schedule
      7.14
      and
      Hedging Agreements set forth on Schedule
      7.21)
      providing for, evidencing, securing or otherwise relating to any Debt of any
      such Obligor or any of its Subsidiaries, and all obligations of Borrower or
      any
      of the Guarantors to issuers of surety or appeal bonds issued for account of
      any
      such Obligor. The Borrower shall also make available to Administrative Agent
      and
      Lenders all Material Agreements and other agreements and instruments (excluding
      any such agreements and other instruments that are cancelable upon 60 or less
      days notice) of Borrower and each of the Obligors relating to the purchase,
      transportation by pipeline, gas processing, marketing, sale and supply of
      natural gas and other Hydrocarbons, but in any event, any such agreement or
      other instrument that will account for more than 10% of the sales of any such
      Obligor during the Borrower’s current fiscal year. Upon request by
      Administrative Agent, the Borrower shall deliver, or caused to be delivered,
      to
      the Administrative Agent and the Lenders a complete and correct copy of all
      such
      Material Agreements.  

     

    Section
      7.24 Gas
      Imbalances.
      As of
      the Closing Date, except as set forth on Schedule
      7.24
      or on
      the most recent certificate delivered pursuant to Section
      8.07(c),
      on a
      net basis there are no gas imbalances, take or pay or other prepayments with
      respect to any of the Obligors’ Oil and Gas Properties which would require any
      such Obligors to deliver, in the aggregate, five percent (5%) or more of the
      monthly production of Hydrocarbons produced from their Oil and Gas Properties
      at
      some future time without then or thereafter receiving fall payment therefor.
       

     

    Section
      7.25 Relationship
      of Obligors.
      The
      Obligors are engaged in related businesses and each Obligor is directly and
      indirectly dependent upon each other Obligor for and in connection with their
      business activities and their financial resources; and each Obligor has
      determined, reasonably and in good faith, that such Obligor will receive
      substantial direct and indirect economic and financial benefits from the
      extensions of credit made under this Agreement, and such extensions of credit
      are in the best interests of such Obligor, having regard to all relevant facts
      and circumstances.  

     

    Section
      7.26 Solvency.
      The
      Borrower and its Subsidiaries individually and on a consolidated basis are
      not
      insolvent as such term is used and defined in the United States Bankruptcy
      Code.

      cause its Subsidiaries to, provide to Administrative Agent undated letters,
      in
      form of Exhibit
      F
      attached

      the
      addressees left blank, authorizing and directing the addressees to make future
      payments attributable to production from the Mortgaged Properties directly

      Administrative Agent for the ratable benefit of the Lenders.  

     

    (ii)
      Borrower and each of its Subsidiaries hereby designates Administrative Agent
      as
      its agent and attorney-in-fact, to act in their name, place, and stead for
      the
      purpose of completing and delivering any and all of the letters in lieu of
      division orders delivered by Borrower and such Subsidiaries to Administrative
      Agent, including, without limitation, completing any blanks contained in such
      letter and attaching exhibits thereto describing the relevant Collateral. The
      Borrower and each of its Subsidiaries hereby ratifies and confirms all that
      Administrative Agent shall lawfully do or cause to be done by virtue of this
      power of attorney and the rights granted with respect to such power of attorney.
      This power of attorney is coupled with the interest of Administrative Agent
      in
      the Collateral, shall commence and be in full force and effect as of the Closing
      Date and shall remain in full force and effect and shall be irrevocable so
      long

      powers conferred on Administrative Agent by this appointment are solely to
      protect the interests of Administrative Agent and each of the Lenders under
      the
      Loan Documents and shall not impose any duty upon Administrative Agent to
      exercise any such powers. Administrative Agent shall be accountable only for
      amounts that it actually receives as a result of the exercise of such powers
      and
      shall not be responsible to Borrower, its Subsidiaries, or any other Person
      for
      any act or failure to act with respect to such powers, except for gross
      negligence or willful misconduct.  

     

    (iii)
      Until such time as Administrative Agent shall notify Borrower and its
      Subsidiaries to the contrary, Borrower and its Subsidiaries shall be entitled
      to
      receive from the purchasers or disbursers of production all such proceeds of
      runs, subject however to the liens created under the Security Instruments.
      Upon
      the occurrence and during the continuance of a Default or such other time as
      Administrative Agent shall in its discretion so elect, Administrative Agent
      may
      deliver to the addressees the letters-in-lieu described in Subsection
      8.09(d)(i) above
      and
      may exercise all rights and remedies granted under the Security Instruments,

      by
      Borrower and its Subsidiaries or to receive directly from the purchaser or
      disburser of production all other proceeds of runs.  

    46

     

    (iv)
      In
      no case shall any failure, whether purposed or inadvertent, by Administrative
      Agent to collect directly any such proceeds of runs constitute in any way a
      waiver, remission or release of any of its rights under the Security
      Instruments, nor shall any release of any other proceeds of runs or of any
      rights of Administrative Agent to collect other proceeds of runs thereafter.
       

     

    (e)

      Properties.  

     

    (iii)
      Following the occurrence and during the continuance of an Event of Default,
      each
      Obligor acknowledges that the Administrative Agent is expressly granted the
      right to exercise any and all liens, statutory or otherwise, rights of offset
      or
      recoupment it has and to receive the monies, income, proceeds, or benefits
      attributable to the sale of Oil and Gas produced from or attributable to the
      Mortgaged Properties, to hold the same as security for the Indebtedness and
      to
      apply it on the principal and interest or other amounts owing on any of the
      Indebtedness, whether or not then due, in such order or manner as Administrative
      Agent may elect.  

     

    (iv)
      In
      the event of a foreclosure, deed in lieu, or other transfer of record or

      Pledge
      of Partnerships.
      Borrower shall and shall cause each of its Wholly Owned Subsidiaries that are
      not Unrestricted Entities to pledge all of its interest in any Partnership
      and
      to provide such information about such Partnership as Lenders may reasonably
      request.

    (g)
      Subordination
      of Intercompany Debt.
      Any
      Intercompany Notes or advances of any Obligor howsoever evidenced by journal
      entries or otherwise now or hereafter owed to or held by any other Obligor
      are
      hereby subordinated to the Indebtedness of such other Obligor to the Lenders,
      and any document or instrument evidencing such loans or advances shall contain
      a
      legend giving notice of such subordination. Any Intercompany Notes or advances
      of any other Obligor due to such Obligor, if the Administrative Agent so
      requests, shall be collected, enforced and received by such Obligor as trustee
      for the Lenders and be paid over to the Administrative Agent for the account
      of
      the Lenders on account of the Indebtedness but without affecting in any manner
      the liability of such Obligor under the other provisions of this Agreement
      or
      any other Loan Document. Any Lien, claim, right or other encumbrance on any
      property of any Obligor in favor of any other Obligor is hereby subordinated
      in
      all respects to the Liens granted to the Administrative Agent for the benefit
      of
      the Lenders.

      that
      (1) no
      such contract shall be for speculative purposes; (2) the floating rate index

      receiving full payment therefor.

      Agent for the ratable benefit of the Lenders all of the proceeds of runs
      accruing to the Mortgaged Properties covered thereby:

      such time as Administrative Agent shall notify such Obligors to the contrary,
      Obligors shall be entitled to receive from the purchasers or disbursers of
      production all such proceeds of runs, subject however to the liens created
      under
      the Mortgages, which liens are hereby affirmed and ratified. Automatically

      then
      held by Obligors or to receive directly from the purchasers or disbursers of
      production all other proceeds of runs.  

     

    (ii)
      In
      no case shall any failure, whether purposed or inadvertent, by Administrative
      Agent to collect directly any such proceeds of runs constitute in any way a
      waiver, remission or release of any of its rights under the Mortgages, nor
      shall
      any release of any other proceeds of runs or of any rights of Administrative
      Agent to collect other proceeds of runs thereafter.  

    56

    

    
    

    (iii)
      Obligors will upon the instruction of Administrative Agent join with
      Administrative Agent in notifying, in writing and accompanied (if necessary)
      by
      certified copies of the Mortgages, the purchasers or disbursers of production,
      produced from the Mortgaged Properties, of the existence of the Mortgages,

      as
“Debtor” thereto (herein collectively the “Pledges”),
      such
      parties have unconditionally assigned to Administrative Agent for the ratable
      benefit of the Lenders all of the dividends, interest, or other “Distributions”
(as defined therein) paid or payable in respect of the Collateral covered
      thereby:  

     

    (i)
      Until
      such time as Administrative Agent shall notify such Obligors to the contrary,
      Obligors shall be entitled to receive and retain all such Distributions, subject
      however to the security interests created under the Pledges, which liens are
      hereby affirmed and ratified. Automatically upon an Event of Default under
      Section
      10.01(f)
      or
(g)
      and upon
      the occurrence and during the continuance of any other Event of Default,
      Administrative Agent may exercise all rights and remedies granted under the
      Pledges, including the right to obtain possession of all Distributions then
      held
      by Obligors or to receive directly from the Subsidiaries and Partnerships making
      such payments all future Distributions attributable to the Collateral.
 

     

    (ii)
      In
      no case shall any failure, whether purposed or inadvertent, by Administrative
      Agent to collect directly any such Distributions constitute in any way a waiver,
      remission or release of any of its rights under the Pledges, nor shall any
      release of any other Distributions or of any rights of Administrative Agent
      to
      collect other Distributions thereafter.  

     

    (iii)
      Obligors will upon the instruction of Administrative Agent join with
      Administrative Agent in notifying in writing to the entities responsible for
      making such Distributions of the existence of the Pledges, and instructing
      that
      all Distributions be paid directly to Administrative Agent for the ratable
      benefit of the Lenders.

      telegram or cable) believed by it to be genuine and correct and to have been
      signed or sent by or on behalf of the proper Person or Persons, and upon advice
      and statements of legal counsel, independent accountants and other experts
      selected by the Administrative Agent.  

     

    Section
      11.03 Defaults.
      The
      Administrative Agent shall not be deemed to have knowledge of the occurrence
      of
      a Default (other than the non-payment of principal of or interest on Loans
      or of
      fees or failure to reimburse for Letter of Credit drawings) unless the
      Administrative Agent has received notice from a Lender or the Borrower
      specifying such Default and stating that such notice is a “Notice
      of Default”.
      In the
      event that the Administrative Agent receives such a notice of the occurrence
      of
      a Default, the Administrative Agent shall give prompt notice thereof to the
      Lenders. In the event of a payment Default, the Administrative Agent shall
      give
      each Lender prompt notice of each such payment Default.  

     

    Section
      11.04 Rights
      as a Lender.
      With
      respect to its Commitments and the Loans made by it and its participation in
      the
      issuance of Letters of Credit, Wachovia Bank, National Association (and any
      successor acting as Administrative Agent) in its capacity as a Lender hereunder
      shall have the same rights and powers hereunder as any other Lender and may
      exercise the same as though it were not acting as the Administrative Agent,
      and
      the term “Lender”
or
      “Lenders”
shall,
      unless the context otherwise indicates, include the Administrative Agent in
      its
      individual capacity. Wachovia Bank, National Association (and any successor
      acting as Administrative Agent) 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 or other business with the
      Obligors (and any of their Affiliates) as if it were not acting as the
      Administrative Agent, and Wachovia Bank, National Association and its Affiliates
      may accept fees and other consideration from the Obligors for services in
      connection with this Agreement or otherwise without having to account for the
      same to the Lenders.  

     

    Section
      11.05 Indemnification.
      The
      Lenders agree to indemnify the Administrative Agent and the Issuing Bank ratably
      in accordance with their Percentage Shares for the indemnity matters as
      described in Section
      12.03
      to the
      extent not indemnified or reimbursed by the Obligors under Section
      12.03,
      but
      without limiting the obligations of the Obligors under said Section
      12.03 and
      for
      any and all other liabilities, obligations, losses, damages, penalties, actions,
      judgments, suits, costs, expenses or disbursements of any kind and nature
      whatsoever which may be imposed on, incurred by or asserted against the
      Administrative Agent or the Issuing Bank in any way relating to or arising
      out
      of: (1) this Agreement, the Security Instruments or any other documents
      contemplated by or referred
      to herein or the transactions contemplated hereby, but excluding, unless a
      Default has occurred and is continuing, normal administrative costs and expenses
      incident to the performance of its agency duties hereunder or (ii) the
      enforcement of any of the terms of this Agreement, any Security Instrument
      or of
      any such other documents; WHETHER OR NOT ANY OF THE FOREGOING SPECIFIED IN
      THIS
SECTION
      11.05
      ARISES
      FROM THE SOLE OR CONCURRENT NEGLIGENCE OF THE ADMINISTRATIVE AGENT OR THE
      ISSUING BANK, provided that no Lender shall be liable for any of the foregoing
      to the extent they arise from the gross negligence or willful misconduct of
      the
      Administrative Agent.  

    58

    

    

     

    Section
      11.06 Non-Reliance
      on Administrative Agent and other Lenders.
      Each
      Lender acknowledges and agrees that it has, independently and without reliance
      on the Administrative Agent or any other Lender, and based on such documents
      and
      information as it has deemed appropriate, made its own credit analysis of the
      Obligors and its decision to enter into this Agreement, and that it will,
      independently and without reliance upon the Administrative Agent or any other
      Lender, and based on such documents and information as it shall deem appropriate
      at the time, continue to make its own analysis and decisions in taking or not
      taking action under this Agreement. The Administrative Agent shall not be
      required to keep itself informed as to the performance or observance by the
      Obligors of this Agreement, the Notes, the Security Instruments or any other
      document referred to or provided for herein or to inspect the properties or
      books of the Obligors. Except for notices, reports and other documents and
      information expressly required to be furnished to the Lenders by the
      Administrative Agent hereunder, the Administrative Agent shall not have any
      duty
      or responsibility to provide any Lender with any credit or other information
      concerning the affairs, financial condition or business of the Obligors (or
      any
      of their Affiliates) which may come into the possession of the Administrative
      Agent or any of its Affiliates. In this regard, each Lender acknowledges that
      Haynes and Boone, LLP is acting in this transaction as special counsel to the
      Administrative Agent only, except to the extent otherwise expressly stated
      in
      any legal opinion or any Loan Document. Each Lender will consult with its own
      legal counsel to the extent that it deems necessary in connection with the
      Loan
      Documents and the matters contemplated therein.  

     

    Section
      11.07 Action
      by Administrative Agent.
      Except
      for action or other matters expressly required of the Administrative Agent
      hereunder, the Administrative Agent shall in all cases be fully justified in
      failing or refusing to act hereunder unless it shall (i) receive written
      instructions from the Majority Lenders (or all of the Lenders as expressly
      required by Section
      12.04)
      specifying the action to be taken, and (ii) be indemnified to its satisfaction
      by the Lenders against any and all liability and expenses which may be incurred
      by it by reason of taking or continuing to take any such action. The
      instructions of the Majority Lenders (or all of the Lenders as expressly
      required by Section
      12.04)
      and any
      action taken or failure to act pursuant thereto by the Administrative Agent
      shall be binding on all of the Lenders. If a Default has occurred and is
      continuing, the Administrative Agent shall take such action with respect to
      such
      Default as shall be directed by the Majority Lenders (or all of the Lenders
      as
      required by Section
      12.04)
      in the
      written instructions (with indemnities) described in this Section
      11.07,
      provided that, unless and until the Administrative Agent shall have received
      such directions, the Administrative Agent may (but shall not be obligated to)
      take such action, or refrain from taking such action, with respect to such
      Default as it shall deem advisable in the best interests of the Lenders. In
      no
      event, however, shall the Administrative Agent be required to take any action
      which exposes the Administrative Agent to personal liability or which is
      contrary to this Agreement and the Security Instruments or applicable law.
       

     

    Section
      11.08 Resignation
      or Removal of Administrative Agent.
      Subject
      to the appointment and acceptance of a successor Administrative Agent as
      provided below, the Administrative Agent may resign at any time by giving notice
      thereof to the Lenders and the Borrower, and the Administrative Agent may be
      removed at any time with or without cause by the Majority Lenders. Upon any
      such
      resignation or removal, the Majority Lenders shall have the right to appoint
      a
      successor Administrative Agent. If no successor Administrative Agent shall
      have
      been so appointed by the Majority Lenders and shall have accepted such
      appointment within thirty (30) days after the retiring Administrative Agent’s
      giving of notice of resignation or the Majority Lenders’ removal
      of the
      retiring Administrative Agent, then the retiring Administrative Agent may,
      on
      behalf of the Lenders, appoint a successor Administrative Agent. Upon the
      acceptance of such appointment hereunder by a successor Administrative Agent,
      such successor Administrative Agent shall thereupon succeed to and become vested
      with all the rights, powers, privileges and duties of the retiring
      Administrative Agent, and the retiring Administrative Agent shall be discharged
      from its duties and obligations hereunder. After any retiring Administrative
      Agent’s resignation or removal hereunder as Administrative Agent, the provisions
      of this Article
      XI
      and
Section
      12.03
      shall
      continue in effect for its benefit in respect of any actions taken or omitted
      to
      be taken by it while it was acting as the Administrative Agent.

    ARTICLE
      XII  

    Miscellaneous

     

    Section
      12.01 Waiver.
      No
      failure on the part of the Administrative Agent or any Lender to exercise and
      no
      delay in exercising, and no course of dealing with respect to, any right, power
      or privilege under any of the Loan Documents shall operate as a waiver thereof,
      nor shall any single or partial exercise of any right, power or privilege under
      any of the Loan Documents preclude any other or further exercise thereof or
      the
      exercise of any other right, power or privilege. The remedies provided herein
      are cumulative and not exclusive of any remedies provided by law.

      Subsidiaries, (iv) the failure of the Obligors or any Subsidiary to comply
      with
      the terms of any loan document, or with any governmental requirement, (v) any
      inaccuracy of any representation or any breach of any warranty of the Obligors
      set forth in any of the loan documents, (vi) the issuance, execution and
      delivery or transfer of or payment or failure to pay under any letter of credit,
      or (vii) the payment of a drawing under any letter of credit notwithstanding

      or willful misconduct on the part of the Indemnified Party; and  

     

    (iii)

      SUBJECT (I) UNDER ANY ENVIRONMENTAL LAW APPLICABLE TO THE OBLIGORS OR ANY
      SUBSIDIARY OR ANY OF THEIR PROPERTIES, INCLUDING WITHOUT LIMITATION, THE
      TREATMENT OR DISPOSAL OF HAZARDOUS SUBSTANCES ON ANY OF THEIR PROPERTIES, (II)

      CONNECTION WITH THE LOAN DOCUMENTS.  

     

    (b)
      No
      Indemnified Party may settle any claim to be indemnified without the consent
      of
      the indemnitor, such consent not to be unreasonably withheld; provided,
      that
      the indemnitor may not reasonably withhold consent to any settlement that an
      Indemnified Party proposes, if the indemnitor does not have the financial
      ability to pay all its obligations outstanding and asserted against the
      indemnitor at that time, including the maximum potential claims against the
      Indemnified Party to be indemnified pursuant to this Section
      12.03.
       

    61

    

    

     

    (c)
      In
      the case of any indemnification hereunder, the Administrative Agent or Lender,
      as appropriate shall give notice to the Obligors of any such claim or demand
      being made against the Indemnified Party and the Obligors shall have the
      non-exclusive right to join in the defense against any such claim or demand
      provided that if any Obligor provides a defense, the Indemnified Party shall
      bear its own cost of defense unless there is a conflict between the Obligors
      and
      such Indemnified Party.  

     

    (d)
      THE
      FOREGOING INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED PARTIES NOTWITHSTANDING
      THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER
      ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT
      LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT
      (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNIFIED PARTIES OR BY REASON OF
      STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNIFIED
      PARTIES. To the extent that an Indemnified Party is found to have committed
      an
      act of gross negligence or willful misconduct, this contractual obligation
      of
      indemnification shall continue but shall only extend to the portion of the
      claim
      that is deemed to have occurred by reason of events other than the gross
      negligence or willful misconduct of the Indemnified Party.  

     

    (e)
      The
      Obligors’ obligations under this Section
      12.03
      shall
      survive any termination of this Agreement and the payment of the Notes and

      continue thereafter in full force and effect.  

     

    (f)
      The
      Obligors shall pay any amounts due under this Section
      12.03
      within
      thirty (30) days of the receipt by the Obligors of notice of the amount due.
       

     

    Section
      12.04 Amendments,
      Etc.
      Any
      provision of this Agreement or any other Loan Document may be amended, modified
      or waived with the Obligors’ and the Majority Lenders’ prior written consent;
      provided that (i) no amendment, modification or waiver which extends the final
      maturity of the Loans, increases the Aggregate Maximum Revolving Credit Amounts,
      increases the Borrowing Base, reduces or forgives the principal amount of any
      Indebtedness outstanding under this Agreement (including any principal due
      pursuant to a mandatory prepayment required pursuant to Section
      2.07(b)),
      postpones any date scheduled for any payment of principal or interest under
      this
      Agreement (including any principal due pursuant to a mandatory prepayment
      required pursuant to Section
      2.07 (b)),
      releases any Guarantor, of the Indebtedness, or releases Security Instruments
      which in the aggregate cover a material portion of the Mortgaged Property (as
      reflected on the most recent Reserve Report delivered under Section
      8.07)
      during
      each Borrowing Base Period, reduces the interest rate applicable to the Loans
      or
      the fees payable to the Lenders generally, affects Section
      2.03(a),
      this
Section
      12.04,
      Section
      12.06(a),
      any
      provision of Section
      4.05(b)
      that
      would alter the pro rata sharing of payments required thereby, or modifies
      the
      definitions of “Majority
      Lenders”
or
      “Percentage
      Share”
shall
      be effective without consent of all Lenders; (ii) no amendment, modification
      or
      waiver which increases the Maximum Revolving Credit Amount or the Commitment
      of
      any Lender shall be effective without the consent of such Lender; and (iii)
      no
      amendment, modification or waiver which modifies the rights, duties or
      obligations of the Administrative Agent shall be effective without the consent
      of the Administrative Agent.  

     

    Section
      12.05 Successors
      and Assigns.
      This
      Agreement shall be binding upon and inure to the benefit of the parties hereto
      and their respective successors and permitted assigns.

    Section
      12.06 Assignments
      and Participations  

     

    (a)
      The
      Borrower may not assign its rights or obligations hereunder or under the Notes
      or any Letters of Credit without the prior consent of all of the Lenders and
      the
      Administrative Agent.  

     

    (b)
      Any
      Lender may, upon the written consent of the Administrative Agent and, if no
      Default exists, with consent of the Borrower (which consent will not be
      unreasonably withheld or delayed), assign to one or more assignees all or a
      portion of its rights and obligations under this Agreement pursuant to an
      Assignment Agreement substantially in the form of Exhibit
      E
      (an
“Assignment”);
      provided,
      however,
      that
      (i) any such assignment shall be in the amount of the lesser of (A) at least
      $5,000,000 or (B) the total amount of a Lender’s rights and obligations under
      this Agreement and (ii) the assignee or assignor shall pay to the Administrative
      Agent a processing and recordation fee of $3,500 for each assignment. Any such
      assignment will become effective upon the execution and delivery to the
      Administrative Agent of the Assignment and the consent of the Administrative
      Agent. Promptly after receipt of an executed Assignment, the Administrative
      Agent shall send to the Borrower a copy of such executed Assignment. Upon
      receipt of such executed Assignment, the Borrower, will, at its own expense,
      execute and deliver new Notes to the assignor and/or assignee, as appropriate,
      in accordance with their respective interests as they appear. Upon the
      effectiveness of any assignment pursuant to this Section
      12.06(b),
      the
      assignee will become a “Lender,”
if
      not
      already a “Lender,”
for
      all purposes of this Agreement and the Security Instruments. The assignor shall
      be relieved of its obligations hereunder to the extent of such assignment (and
      if the assigning Lender no longer holds any rights or obligations under this
      Agreement, such assigning Lender shall cease to be a “Lender”
      hereunder except that its rights under Sections
      4.06, 5.01, 5.05
      and
12.03
      shall
      not be affected).  

     

    (c)
      Each
      Lender may transfer, grant or assign participations in all or any part of such
      Lender’s interests hereunder pursuant to this Section
      12.06(c)
      to any
      Person, provided
      that:
      (i) such Lender shall remain a “Lender”
for
      all
      purposes of this Agreement and the transferee of such participation shall not
      constitute a “Lender”
      hereunder; and (ii) no participant under any such participation shall have
      rights to approve any amendment to or waiver of any of the Loan Documents except
      to the extent such amendment or waiver would (w) modify the definition of
“Majority
      Lenders,”
(x)
      forgive any principal owing on any Indebtedness or extend the final maturity
      of
      the Loans, (y) reduce the interest rate (other than as a result of waiving
      the
      applicability of any post-default increases in interest rates) or fees
      applicable to any of the Commitments or Loans or Letters of Credit in which
      such
      participant is participating, or postpone the payment of any thereof, or (z)
      release any guarantor of the Indebtedness or release Security Instruments which

Section
      8.07)
      during
      each Borrowing Base Period supporting any of the Commitments or Loans or Letters
      of Credit in which such participant is participating. In the case of any such
      participation, the participant shall not have any rights under this Agreement
      or
      any of the Security Instruments (the participant’s rights against the granting
      Lender in respect of such participation to be those set forth in the agreement
      with such Lender creating such participation), and all amounts payable by the
      Borrower hereunder shall be determined as if such Lender had not sold such
      participation, provided
      that
      such participant shall be entitled to receive additional amounts under
Article
      V

      such Persons agree to be bound by the provisions of Section
      12.15.

      12.06
      to the
      contrary, any Lender may assign and pledge its Note to any Federal Reserve

      No such assignment and/or pledge shall release the assigning and/or pledging
      Lender from its obligations hereunder.

    (f)
      Notwithstanding any other provisions of this Section
      12.06,
      no
      transfer or assignment of the interests or obligations of any Lender or any
      grant of participations therein shall be permitted if such transfer, assignment
      or grant would require the Borrower to file a registration statement with the
      SEC or to qualify the Loans under the “Blue
      Sky”
laws
      of
      any state.

      12.07 Invalidity.
      In the
      event that any one or more of the provisions contained in any of the Loan
      Documents shall, for any reason, be held invalid, illegal or unenforceable
      in
      any respect, such invalidity, illegality or unenforceability shall not affect
      any other provision of the Notes, this Agreement or any other Loan Document.
       

     

    Section
      12.08 Counterparts.
      This
      Agreement may be executed in any number of counterparts, all of which taken
      together shall constitute one and the same instrument and any of the parties

      shall
      survive the repayment of the Loans and the termination of the Commitments.

      aside or required to be repaid to a trustee, debtor in possession, receiver
      or
      other Person under any bankruptcy law, common law or equitable cause, then

    Section
      12.14 Interest.
      It is
      the intention of the parties hereto to conform strictly to Applicable Usury
      Laws
      regarding the use, forbearance or detention of the indebtedness evidenced by
      this Agreement, the Notes and the other Loan Documents, whether such laws are
      now or hereafter in effect, including the laws of the United States of America
      or any other jurisdiction whose laws are applicable, and including any
      subsequent revisions to or judicial interpretations of those laws, in each
      case
      to the extent they are applicable to this Agreement, the Notes and the other
      Loan Documents (the “Applicable
      Usury Laws”).
      Accordingly, if any acceleration of the maturity of the Notes or any payment
      by
      Borrower or any other Person produces a rate in excess of the Highest Lawful
      Rate or otherwise results in Borrower or such other Person being deemed to
      have
      paid any interest in excess of the Maximum Amount, as hereinafter defined,
      or if
      any Lender shall for any reason receive any unearned interest in violation
      of
      any Applicable Usury Laws, or if any transaction contemplated hereby would
      otherwise be usurious under any Applicable Usury Laws, then, in that event,
      regardless of any provision contained in this Agreement or any other Loan
      Document or other agreement or instrument executed or delivered in connection
      herewith, the provisions of this Section
      12.14
      shall
      govern and control, and neither Borrower nor any other Person shall be obligated
      to pay, or apply in any manner to, any amount that would be excessive interest.
      No Lender shall ever be deemed to have contracted for or be entitled to receive,
      collect, charge, reserve or apply as interest on any Loan (whether termed
      interest therein or deemed to be interest by judicial determination or operation
      of law), any amount in excess of the Highest Lawful Rate, and, in the event
      that
      such Lender ever receives, collects, or applies as interest any such excess,
      such amount which would be excessive interest shall be applied as a partial
      prepayment of principal and treated hereunder as such, and, if the principal
      amount of the applicable Loans are paid in full, any remaining excess shall
      forthwith be paid to Borrower. In determining whether or not the interest
      contracted for, received, collected, charged, reserved, paid or payable,
      including under any specific contingency, exceeds the Highest Lawful Rate,
      Borrower and each Lender shall, to the maximum extent permitted under applicable
      law, (a) characterize any non-principal payment (other than payments which
      are
      expressly designated as interest payments hereunder) as an expense or fee rather
      than as interest, (b) exclude voluntary prepayments and the effect thereof,
      and
      (c) amortize and spread the total amount of interest throughout the entire
      stated term of the Loans so that the interest rate is uniform throughout such
      term; provided
      that
      if
      the Loans are paid in full prior to the end of the full contemplated term
      hereof, and if the interest received for the actual period of existence thereof
      exceeds the Highest Lawful Rate, if any, then the Lenders shall refund to
      Borrower the amount of such excess, or credit the amount of such excess against
      the aggregate unpaid principal balance of all Loans made by Lender. As used
      herein, the term “Maximum
      Amount”
      means
      the maximum nonusurious amount of interest which may be lawfully contracted
      for,
      reserved, charged, collected or received by Lender in connection with the
      indebtedness evidenced by this Agreement, the Notes and other Loan Documents
      under all Applicable Usury Laws. Texas Finance Code, Chapter 346, which
      regulates certain revolving loan accounts and revolving tri-party accounts,
      shall not apply to any revolving loan accounts created under, or apply in any
      manner to, the Note, this Agreement or the other Loan Documents.

    Section
      12.15 Confidentiality.
      Subject
      to provisions under Section
      12.16
      below,
      in the event that the Borrower provides to the Administrative Agent or the
      Lenders written confidential information belonging to the Borrower, if the
      Borrower shall denominate such information in writing as “confidential,”
the
      Administrative Agent and the Lenders shall thereafter maintain such information
      in confidence
      in accordance with the standards of care and diligence that each utilizes in
      maintaining its own confidential information. This obligation of confidence
      shall not apply to such portions of the information which (i) are in the public
      domain, (ii) hereafter become part of the public domain without the
      Administrative Agent or the Lenders breaching their obligation of confidence
      to
      the Borrower, (iii) are previously known by the Administrative Agent or the
      Lenders from some source other than the Borrower, (iv) are hereafter developed
      by the Administrative Agent or the Lenders without using the Borrower’s
      information, (v) are hereafter obtained by or available to the Administrative
      Agent or the Lenders from a third party who owes no obligation of confidence
      to
      the Borrower with respect to such information or through any other means other
      than through disclosure by the Borrower, (vi) are disclosed with the Borrower’s
      consent, (vii) must be disclosed either pursuant to any Governmental Requirement
      or to Persons regulating the activities of the Administrative Agent or the
      Lenders provided, Administrative Agent and Lenders shall endeavor to provide
      notice to the Borrower as soon as practicable in the event Borrower desires
      to
      enjoin the disclosure of such information, however, failure of Administrative
      Agent or Lenders to provide such prior notice to Borrower shall not give rise
      to
      any claim or cause of action by Borrower or any Obligor against Administrative
      Agent or such Lenders, (viii) as may be required by law or regulation or order
      of any Governmental Authority in any judicial, arbitration or governmental
      proceeding, or (ix) are disclosed to any actual or prospective counterparty
      (or
      its advisors) to any swap or derivative transaction relating to the Borrower
      and
      its obligations. Further, the Administrative Agent or a Lender may disclose
      any
      such information to any other Lender, any independent petroleum engineers or
      consultants, any independent certified public accountants, any legal counsel
      employed by such Person in connection with this Agreement or any Security
      Instrument, including without limitation, the enforcement or exercise of all
      rights and remedies thereunder, or any assignee or participant (including
      prospective assignees and participants) in the Loans; provided, however, that
      the Administrative Agent or the Lenders shall receive a confidentiality
      agreement from the Person to whom such information is disclosed such that said
      Person shall have the same obligation to maintain the confidentiality of such
      information as is imposed upon the Administrative Agent or the Lenders
      hereunder. Notwithstanding anything to the contrary provided herein, this
      obligation of confidence shall cease three (3) years from the date the
      information was furnished, unless the Borrower requests in writing at least
      thirty (30) days prior to the expiration of such three year period, to maintain
      the confidentiality of such information for an additional three year period.
      The
      Borrower waives any and all other rights it may have to confidentiality as
      against the Administrative Agent and the Lenders arising by contract, agreement,
      statute or law except as expressly stated in this Section
      12.15.
       

     

    Section
      12.16 USA
      Patriot Act Notice.
      Each
      Lender hereby notifies the Borrower that pursuant to the requirements of the
      USA
      Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001))
      (the “Act”),
      it is
      required to obtain, verify and record information that identifies the Borrower,
      which information includes the name and address of the Borrower and other
      information that will allow such Lender to identify the Borrower in accordance
      with the Act.

    Re:
      Letter in Lieu of Transfer Order 

     

    Gentlemen:
      

     

    [____________________],
      as Mortgagor, has executed the mortgages and financing statements described
      on
Exhibit
      A attached
      hereto (the “Mortgage”)
      for
      the benefit of Wachovia Bank, National Association, as administrative agent
      (“Lender”),
      granting a mortgage on and pledging those certain properties (the “Pledged
      Properties”)
      described in the Mortgage to secure certain obligations also described in the
      Mortgage. Enclosed is a copy of the Mortgage covering the Pledged Properties.
      

     

    Exhibit
      B
      attached
      hereto lists the properties which are subject to the Mortgage for which you
      are
      accounting to Mortgagor and the decimal interest in production heretofore paid
      to Mortgagor with respect to its interest in each given property. 

     

    Pursuant
      to the assignment of production provision in the Mortgage, Mortgagor transferred
      and assigned all of its interests in the Pledged Properties to Lender.
      Therefore, Mortgagor hereby authorizes and instructs you that all future
      payments attributable to the Pledged Properties, which would otherwise be paid
      to Mortgagor, should be made to: 

    

    
      	
              if
                by wire transfer:

            	
              Wachovia
                Bank, National Association

            
	 	
              ______________________________________________

            
	 	
              ______________________________________________

            
	 	
              ______________________________________________

            
	 	
              Account
                No. _____________________

            
	 	 
	
              if
                by check, check made payable to:

            	
              ______________________________________________

            
	 	
              ______________________________________________

            

    

    

    until
      notified in writing by Lender to discontinue such payments. Also, Mortgagor
      hereby requests that you change your records to reflect that Lender is entitled
      to the proceeds of production attributable to the Pledged Properties.

     

    In
      consideration of your acceptance of this Letter-in-Lieu of Transfer Order,
      Lender and Mortgagor agree as follows: 

     

    1.
      Mortgagor has heretofore executed Transfer or Division Orders to you covering
      each of the properties referred to in Exhibit
      B
      attached
      to this letter. This letter is being executed by the undersigned in lieu of
      execution of separate Transfer or Division Orders. With respect to proceeds
      from
      the sale of oil, gas and other hydrocarbons as to which you account hereunder,
      Lender agrees that it will be bound by the terms, conditions, warranties and
      covenants of all such Transfer or Division Orders heretofore executed by
      Mortgagor now in force, with the same effect as though it had executed the
      originals thereof; provided,
      however,
      the
      aggregate liability of Lender with respect to any warranty, representation,
      covenant or indemnification contained therein or in this letter shall be limited
      to an amount equal to the amounts disbursed by you to Lender hereunder.

     

    Exhibit
      F
– Page 1 

    

    
    

    2.
      Mortgagor hereby agrees that you are relieved of any responsibility in
      connection with the application of the proceeds paid by you to Lender as
      hereinabove specified and payment made by you to Lender shall be binding and
      conclusive as between you and Mortgagor. 

     

    In
      the
      absence of a question about the enclosed schedule, you are respectfully
      requested to make disbursement to Lender as instructed herein and NOT TO SUSPEND
      OR DELAY any payments by virtue of the assignment of production from Mortgagor
      to Lender. Should you require additional documentation prior to implementing
      the
      manner of disbursement requested herein, notwithstanding the warranties and
      indemnifications contained hereinabove, please suspend disbursements to
      Mortgagor, pending execution of such additional documentation as you may
      reasonably require. 

     

    In
      order
      that we may have a record evidencing your acceptance of this Letter-in-Lieu
      of
      Transfer Order, we request that you execute one copy of this letter in the
      space
      provided below and return the same to Lender in the enclosed self-addressed
      envelope. 

     

    
      	 	 	 
	 	
               Very
                truly yours,

      amount of such liability that can be hereby incurred without rendering this
      Guaranty Agreement, as it relates to the Guarantor, voidable under applicable
      law relating to fraudulent conveyance or fraudulent transfer, and not for any
      greater amount. This Guaranty Agreement constitutes a guaranty of payment when
      due and not of collection, and the Guarantor specifically agrees that it shall
      not be necessary or required that any Lender or any holder of any Note exercise
      any right, assert any claim or demand or enforce any remedy whatsoever against
      the Borrower or any other Obligor (or any other Person) before or as a condition
      to the obligations of the Guarantor hereunder.

    SECTION
      2.2 Acceleration
      of Guaranty Agreement.
      The
      Guarantor agrees that, in the event of the occurrence of any event of the type
      described in Section
      10.01(e), (f) or (g)
      of the
      Credit Agreement, with respect to the Borrower, any other Obligor or the
      Guarantor, and if such event shall occur at a time when any of the Indebtedness
      may not then be due and payable by the Borrower due to any automatic stay or
      other debtor relief laws, the Guarantor will pay to the Lenders forthwith the
      full amount which would be payable hereunder by the Guarantor if all such
      Indebtedness were then due and payable. 

     

    SECTION
      2.3 Guaranty
      Agreement Absolute, etc.
      This
      Guaranty Agreement shall in all respects be a continuing, absolute,
      unconditional and irrevocable guaranty of payment, and shall remain in full
      force and effect until all Indebtedness of the Borrower and each other Obligor
      has been paid in full, all obligations of the Guarantor hereunder shall have
      been paid in full, all Commitments shall have terminated and all Lender Hedging
      Agreements have terminated. Guarantor may not rescind or revoke its obligations
      hereunder. The Guarantor guarantees that the Indebtedness of the Borrower and
      each other Obligor will be paid strictly in accordance with the terms of the
      Credit Agreement and each other Loan Document under which they arise, regardless
      of any law, regulation or order now or hereafter in effect in any jurisdiction
      affecting any of such terms or the rights of any Lender or any holder of any
      Note with respect thereto. The liability of the Guarantor under this Guaranty
      Agreement shall be absolute, unconditional and irrevocable irrespective of:
      (1)
      any lack of validity, legality or enforceability of the Credit Agreement, any
      Note or any other Loan Document; (2) the failure of any Lender or any holder
      of
      any Note (a) to assert any claim or demand or to enforce any right or remedy
      against the Borrower, any other Obligor or any other Person (including any
      other
      guarantor) under the provisions of the Credit Agreement, any Note, any other
      Loan Document or otherwise, or (b) to exercise any right or remedy against
      any
      other guarantor of, or collateral securing, any Indebtedness of the Borrower
      or
      any other Obligor; (3) any change in the time, manner or place of payment of,
      or
      in any other term of, all or any of the Indebtedness of the Borrower or any
      other Obligor, or any other extension, compromise or renewal of any Indebtedness
      of the Borrower or any other Obligor; (4) any reduction, limitation, impairment
      or termination of any Indebtedness of the Borrower or any other Obligor for
      any
      reason, including any claim of waiver, release, surrender, alteration or
      compromise, and shall not be subject to (and the Guarantor hereby waives any
      right to or claim of) any defense or setoff, counterclaim, recoupment or
      termination whatsoever by reason of the invalidity, illegality, nongenuineness,
      irregularity, compromise, unenforceability of, or any other event or occurrence
      affecting, any Indebtedness of the Borrower, any other Obligor or otherwise;
      (5)
      any amendment to, rescission, waiver, or other modification of, or any consent
      to departure from, any of the terms of the Credit Agreement, any Note or any
      other Loan Document; (6) any addition, exchange, release, surrender or
      non-perfection of any collateral, or any amendment to or waiver or release
      or
      addition of, or consent to departure from, any other guaranty, held by any
      Lender or any holder of any Note securing any of the Indebtedness of the
      Borrower or any other Obligor; (7) the insolvency or bankruptcy of, or similar
      event affecting, the Borrower or any other Obligor; or (8) any other
      circumstance which might otherwise constitute a defense available to, or a
      legal
      or equitable discharge of, the Borrower, any other Obligor, any surety or any
      guarantor. Guarantor waives all rights and defenses which may arise with respect
      to any of the foregoing, and Guarantor waives any right to revoke this Guaranty
      Agreement with respect to future indebtedness. Guarantor
      waives all rights or defenses under (1) Section
      34.01 et seq.
      of
      the Texas Business and Commerce Code,
      as
      amended, (2) Section
      17.001 of the Texas Civil Practice and Remedies Code,
      as
      amended, (3) Rule
      31 of the Texas Rules of Civil Procedure,

    SECTION
      2.4 Reinstatement.
      The
      Guarantor agrees that this Guaranty Agreement shall continue to be effective
      or
      be reinstated, as the case may be, if at any time any payment (in whole or
      in
      part) of any of the Indebtedness is rescinded or must otherwise be restored
      by
      any Lender or any holder of any Note, upon the insolvency, bankruptcy or
      reorganization of the Borrower, any other Obligor or otherwise, all as though
      such payment had not been made. 

     

    SECTION
      2.5 Waiver,
      etc.
      The
      Guarantor hereby waives promptness, diligence, notice of acceptance and any
      other notice with respect to any of the Indebtedness of the Borrower or any
      other Obligor and this Guaranty Agreement and any requirement that the
      Administrative Agent, any other Lender or any holder of any Note protect,
      secure, perfect or insure any security interest or Lien, or any property subject
      thereto, or exhaust any right or take any action against the Borrower, any
      other
      Obligor or any other Person (including any other guarantor) or entity or any
      collateral securing the Indebtedness of the Borrower or any other Obligor,
      as
      the case may be. 

     

    SECTION
      2.6 Waiver
      of Subrogation.
      Until
      the Indebtedness is paid in full, all Commitments have terminated and all Lender
      Hedging Agreements have terminated, the Guarantor shall not enforce or exercise
      any claim or other rights which it may now or hereafter acquire against the
      Borrower or any other Obligor that arise from the existence, payment,
      performance or enforcement of the Guarantor’s obligations under this Guaranty
      Agreement or any other Loan Document, including any right of subrogation,
      reimbursement, exoneration, or indemnification, any right to participate in
      any
      claim or remedy of the Lenders against the Borrower or any other Obligor or
      any
      collateral which the Administrative Agent now has or hereafter acquires, whether
      or not such claim, remedy or right arises in equity, or under contract, statute
      or common law, including the right to take or receive from the Borrower or
      any
      other Obligor, directly or indirectly, in cash or other property or by set-off
      or in any manner, payment or security on account of such claim or other rights.
      If any amount shall be paid to the Guarantor in violation of the preceding
      sentence, such amount shall be deemed to have been paid to the Guarantor for
      the
      benefit of, and held in trust for, the Lenders, and shall forthwith be paid
      to
      the Lenders to be credited and applied upon the Indebtedness, whether matured
      or
      unmatured. The Guarantor acknowledges that it will receive direct and indirect
      benefits from the financing arrangements contemplated by the Credit Agreement
      and that the waiver set forth in this Section is knowingly made in contemplation
      of such benefits. 

     

    SECTION
      2.7 Payments
      Free and Clear of Taxes, etc.
      The
      Guarantor hereby agrees that: 

     

    (a)
      All
      payments by the Guarantor hereunder shall be made in accordance with
Section
      4.06
      of the
      Credit Agreement free and clear of and without deduction for any present or
      future income, excise, stamp or franchise taxes and other taxes, fees, duties,
      withholdings or other charges of any nature whatsoever imposed by any taxing
      authority, but excluding franchise taxes and taxes imposed on or measured by
      any
      Lender’s net income or receipts (such non-excluded items being called
“Taxes”).
      In
      the event that any withholding or deduction from any payment to be made by
      the
      Guarantor hereunder is required in respect of any Taxes pursuant to any
      applicable law, rule or regulation, then the Guarantor will (i) pay directly
      to
      the relevant authority the full amount required to be so withheld or deducted;
      (ii) promptly forward to such Lender an official receipt or other documentation
      satisfactory to such Lender evidencing such payment to such authority; and
      (iii)
      pay to such Lender such additional amount or amounts as is necessary to ensure
      that the net amount actually received by such Lender will equal the full amount
      such Lender would
      have received had no such withholding or deduction been required. Moreover,
      if
      any Taxes are directly asserted against any Lender with respect to any payment
      received by such Lender hereunder, such Lender may pay such Taxes and the
      Guarantor will promptly pay such additional amounts (including, if incurred
      as a
      result of Guarantor’s or the Borrower’s action, omission or delay, any
      penalties, interest or expenses) as is necessary in order that the net amount
      received by such Lender after the payment of such Taxes (including any Taxes
      on
      such additional amount) shall equal the amount such Lender would have received
      had such Taxes not been asserted. 

    

    Exhibit

    (b)
      If
      the Guarantor fails to pay any Taxes when due to the appropriate taxing
      authority or fails to remit to any Lender the required receipts or other
      required documentary evidence, the Guarantor shall indemnify such Lender for
      any
      incremental Taxes, interest or penalties that may become payable by such Lender
      as a result of any such failure. 

     

    (c)
      Without prejudice to the survival of any other agreement of the Guarantor
      hereunder, the agreements and obligations of the Guarantor contained in this
      Section
      2.7
      shall
      survive the payment in full of the principal of and interest on the Loans.
      

     

    SECTION
      2.8 Contribution
      Agreement.
      Upon
      full and final payment of the Indebtedness, Guarantor and all other Guarantors
      which have made payments upon all or any part of the Indebtedness shall be
      entitled to contribution from all of the other Guarantors, to the end that
      all
      such payments upon the Indebtedness shall be shared among all Guarantors who
      guaranteed such Indebtedness in proportion to their respective Net Worths
      (defined below), provided that the contribution obligations of each of the
      Guarantors shall be limited to the maximum amount that it can pay at such time
      without rendering its contribution obligations voidable under applicable law
      relating to fraudulent conveyances or fraudulent transfers. As used in this
      subsection, the “Net Worth” of each of the Guarantors means, at any time, the
      remainder of (i) the fair value of such Guarantor’s assets (other than such
      right of contribution), minus (ii) the fair value of such Guarantor’s
      liabilities (other than its liabilities under its guaranty of the Indebtedness).
      

     

    SECTION
      2.9 Subordination.
      Guarantor hereby subordinates and makes inferior to the Indebtedness any and
      all
      Intercompany Debt now or at any time hereafter owed by the Borrower or other
      Obligor to the Guarantor. Guarantor agrees that after the occurrence of any
      Default or Event of Default under the Credit Agreement, it will not permit
      the
      Borrower to repay such Intercompany Debt or any part thereof and it will not
      accept payment from the Borrower of such Intercompany Debt or any part thereof
      without the prior written consent of the Majority Lenders as defined in the
      Credit Agreement. If Guarantor receives any such payment without the prior
      required written consent, the amount so paid shall be held in trust for the
      benefit of the Lenders, shall be segregated from the other funds of such
      Guarantor, and shall forthwith be paid over to the Administrative Agent to
      be
      held by the Administrative Agent as collateral for, or then or at any time
      thereafter applied in whole or in part by the Administrative Agent against,
      all
      or any portions of the Indebtedness, whether matured or unmatured, in such
      order
      as the Administrative Agent shall elect.

    SECTION
      4.1 Loan
      Document.
      This
      Guaranty Agreement is a Loan Document executed pursuant to the Credit Agreement
      and shall (unless otherwise expressly indicated herein) be construed,
      administered and applied in accordance with the terms and provisions thereof.
      

     

    SECTION
      4.2 Releases.
      At such
      time as the Loans shall have been paid in full, the Commitments have been
      terminated and no Lender Hedging Agreements are outstanding, the Administrative
      Agent shall, at the request and expense of the Guarantor following such
      termination, promptly execute and deliver to the Guarantor such documents and
      instruments as the Guarantor shall reasonably request to evidence termination
      and release of this Guaranty Agreement. 

     

    SECTION
      4.3 Administrative
      Agent and Lenders; Successors and Assigns.
      

     

    (a)
      The
      Administrative Agent is Administrative Agent for each Lender under the Credit
      Agreement. All rights granted to Administrative Agent under or in connection
      with this Guaranty Agreement are for each Lender’s ratable benefit. The
      Administrative Agent may, without the joinder of any Lender, exercise any rights
      in Administrative Agent’s or Lenders’ favor under or in connection with this
      Guaranty Agreement. The Administrative Agent’s and each Lender’s rights and
      obligations vis-a-vis
      each
      other may be subject to one or more separate agreements between those parties.
      However, the Guarantor is not required to inquire about any such agreement
      and
      is not subject to any terms of it unless the Guarantor specifically enters
      into
      such agreement. Therefore, neither Guarantor nor its successors or assigns
      is
      entitled to any benefits or provisions of any such separate agreement nor is
      it
      entitled to rely upon or raise as a defense any party’s failure or refusal to
      comply with the provisions of any such agreement. 

     

    (b)
      This
      Guaranty Agreement benefits the Administrative Agent, the Lenders, and their
      respective successors and assigns and binds Guarantor and its successors and
      assigns. Upon appointment of any successor Administrative Agent under the Credit
      Agreement, all of the rights of Administrative Agent under this Guaranty
      Agreement automatically vests in that new Administrative Agent as successor
      Administrative Agent on behalf of Lenders without any further act, deed,
      conveyance, or other formality other
      than
      that
      appointment. The rights of the Administrative Agent and the Lenders under this
      Guaranty Agreement may be transferred with any assignment of the obligations
      hereby guaranteed pursuant to and in accordance with the terms of the Credit
      Agreement. The Credit Agreement contains provisions governing assignments of
      the
      obligations guaranteed under this Guaranty Agreement. 

     

    SECTION
      4.4 Amendments,
      etc.
      No
      amendment to or waiver of any provision of this Guaranty Agreement, nor consent
      to any departure by the Guarantor herefrom, shall in any event be effective
      unless the same shall be in writing and signed by or on behalf of the party
      against whom it is sought to be enforced and is in conformity with the
      requirements of Section
      12.04
      of the
      Credit Agreement. Each such waiver or consent shall be effective only in the
      specific instance and for the specific purpose for which given.

      A.
        Debtor, Wachovia Bank, National Association, as Administrative Agent (including
        its permitted successors and assigns in such capacity, the “Administrative
        Agent”),
        and
        Lenders now or hereafter party to the Credit Agreement (including their
        respective permitted successors and assigns, the “Lenders”)
        have
        entered into a Revolving Credit Agreement dated as of December 18, 2006 (as
        amended, modified, supplemented, or restated from time to time, the “Credit
        Agreement”);
        

       

      B.
        This
        Security Agreement is integral to the transactions contemplated by the Loan
        Documents (as defined in the Credit Agreement), and the execution and delivery
        hereof, is a condition precedent to Lenders’ Indebtedness to extend credit under
        the Loan Documents. 

       

      ACCORDINGLY,
        for valuable consideration, the receipt and adequacy of which are hereby

        TO CREDIT AGREEMENT.
        The
        terms, conditions, and provisions of the Credit Agreement are incorporated
        herein by reference, the same as if set forth herein verbatim, which terms,
        conditions, and provisions shall continue to be in full force and effect
        hereunder so long as Lenders are obligated to lend under the Credit Agreement
        and thereafter until the Indebtedness is paid and performed in full.

       

      2.

        defined in either of the Credit Agreement or in the UCC is used in this Security
        Agreement with the same meaning; provided
        that,

        of the
        UCC, the Chapter
        9
        definition shall prevail. As used herein, the following terms have the meanings
        indicated:

        INTEREST.
        In order

      5.
        REPRESENTATIONS
        AND WARRANTIES.
        Debtor
        represents and warrants to Secured Party that: 

       

      (a)
        Credit
        Agreement.
        To the
        extent certain representations and warranties in the Credit Agreement are
        applicable to it or its assets or operations, each such representation and
        warranty is true and correct. 

       

      (b)
        Binding
        Indebtedness/Perfection.
        This
        Security Agreement creates a legal, valid, and binding Lien in and to the
        Collateral in favor of Secured Party and enforceable against Debtor. For
        Collateral in which the Security Interest may be perfected by the filing
        of
        Financing Statements, once those Financing Statements have been properly
        filed
        in the jurisdictions described on Annex
        A hereto,
        the Security Interest in that Collateral will be fully perfected and the
        Security Interest will constitute a first-priority Lien on such Collateral,
        subject only to Excepted Liens or, to the extent Financing Statements have
        already been filed in the jurisdictions described on Annex
        A
        hereto,
        and such Financing Statements have not lapsed, the Security Interest in that
        Collateral is currently perfected and constitutes a first-priority Lien on
        such
        Collateral, subject only to Excepted Liens. With respect to Collateral
        consisting of investment property (other
        than
        Pledged
        Securities covered by Paragraph
        5(j)),
        upon
        the delivery of such Collateral to Secured Party or delivery of an executed
        Control Agreement with respect to such Collateral, the
        Security Interest in that Collateral will be fully perfected and the Security
        Interest will constitute a first-priority Lien on such Collateral, subject
        only
        to Excepted Liens. None of the Collateral has been delivered nor control
        with
        respect thereto given to any other Person. Other than the Financing Statements
        and Control Agreements with respect to this Security Agreement, there are
        no
        other financing statements or control agreements covering any Collateral,
        other
        than those evidencing Excepted Liens. The creation of the Security Interest
        does
        not require the consent of any Person that has not been obtained.

        No
        Authorization, approval, or other action by, and no notice to or filing with,

        the
        exercise by Secured Party of the voting or other rights provided for in this
        Security Agreement or the remedies in respect of the Collateral pursuant
        to this
        Security Agreement (except
        as may
        be required in connection with the disposition of the Pledged Securities
        by laws
        affecting the offering and sale of securities generally). 

       

      (f)
        Maintenance
        of Collateral.
        All

        Shares,
        Partnership Interests, and Material Agreements in which Debtor has any rights,
        titles, or interest (but such failure of such description to be accurate
        or
        complete shall not impair the Security Interest in such Collateral).

       

      (i)
        Instruments,
        Chattel Paper, Collateral Notes, and Collateral Note Security.
        All
        instruments and chattel paper, including, without limitation, the Collateral
        Notes, have been delivered to Secured Party, together
        with
        corresponding endorsements duly executed by Debtor in favor of Secured Party,
        and such endorsements have been duly and validly executed and are binding
        and
        enforceable against Debtor in accordance with their terms. Each Collateral
        Note
        and the documents evidencing the Collateral Note Security are in full force
        and
        effect; there have been no renewals or extensions of, or amendments,
        modifications, or supplements to, any thereof about which the Secured Party
        has
        not been advised in writing; and no “default”
        or
“event
        of default”
        has
        occurred and is continuing under any such Collateral Note or documents
        evidencing the Collateral Note Security. Debtor has good title to the Collateral
        Notes and Collateral Note Security, and such Collateral Notes and Collateral
        Note Security are free from any claim for credit, deduction, or allowance
        of a
        Collateral Obligor and free from any defense, condition, dispute, setoff,
        or
        counterclaim, and there is no extension or indulgence with respect thereto.

      (j)
        Pledged
        Securities; Pledged Shares.
        All
        Collateral that is Pledged Shares is duly authorized, validly issued, fully
        paid, and non-assessable, and the transfer thereof is not subject to any
        restrictions, other than restrictions imposed by applicable securities and
        corporate laws. The Pledged Securities include 100% of the issued and
        outstanding common stock or other equity interests of each Subsidiary owned
        by
        Debtor. As of the date hereof, no shares of capital stock or other equity
        securities are issued, reserved for issuance or outstanding, and there are
        no
        other options, warrants or other rights presently outstanding to purchase
        or
        otherwise acquire any authorized but unissued, unauthorized or treasury shares
        of capital stock of any subsidiary. None of the Pledged Shares is subject
        to
        preemptive rights. Debtor has good title to the Pledged Securities, free
        and
        clear of all Liens and encumbrances thereon (except
        for the
        Security Interest created hereby), and has delivered to Secured Party (i)
        all
        stock certificates, or other instruments or documents representing or evidencing
        the Pledged Securities, together
        with
        corresponding assignment or transfer powers duly executed in blank by Debtor,
        and such powers have been duly and validly executed and are binding and
        enforceable against Debtor in accordance with their terms or (ii) to the
        extent
        such Pledged Securities are uncertificated, an executed Control Agreement
        with
        respect to such Pledged Securities. The pledge of the Pledged Securities
        in
        accordance with the terms hereof creates a valid and perfected first priority
        security interest in the Pledged Securities securing payment of the
        Indebtedness. 

       

      (k)
        Partnership
        Interests.
        Each
        Partnership issuing a Partnership Interest, is duly organized, currently
        existing, and in good standing under all applicable laws; there have been
        no
        amendments, modifications, or supplements to any agreement or certificate
        creating any Partnership or any material contract relating to the Partnerships,
        of which Secured Party has not been advised in writing; no default or breach
        or
        event of default or breach has occurred and is continuing under any Partnership
        Agreement; and no approval or consent of the partners of any Partnership
        is
        required as a condition to the validity and enforceability of the Security
        Interest created hereby or the consummation of the transactions contemplated
        hereby which has not been duly obtained by Debtor. Debtor has good title
        to the
        Partnership Interests free and clear of all Liens and encumbrances (except
        for the
        Security Interest granted hereby). The Partnership Interests are validly
        issued,
        fully paid, and nonassessable and are not subject to statutory, contractual,
        or
        other restrictions governing their transfer, ownership, or control, which
        would
        materially adversely affect the rights of the Lenders hereunder or the ability
        of the Secured Party to exercise its rights or remedies with respect to the
        Partnership Interests, except
        as set
        forth on Annex
        C or
        applicable securities laws. None of the Partnership Interests is subject
        to
        preemptive rights. All capital contributions required to be made by the terms
        of
        the Partnership Agreements for each Partnership have been made. 

       

      (l)
        Accounts;
        General Intangibles.
        All
        Collateral that is accounts or general intangibles is free from any claim
        for
        credit, deduction, or allowance of a Collateral Obligor and free from any
        defense, condition, dispute, setoff, or counterclaim, and there is no extension
        or indulgence with respect thereto. 

       

      (m)
        Material
        Agreements.
        All
        Material Agreements to which Debtor is a party are set forth on Schedule
        7.23 to
        the
        Credit Agreement. Each Material Agreement is in full force and effect; there
        have been no amendments, modifications, or supplements to any Material Agreement
        of which Secured Party has not been advised in writing; and no default or
        breach
        or event of default or breach has occurred and is continuing under any Material
        Agreement. 

       

      The
        foregoing representations and warranties will be true and correct in all
        respects with respect to any additional Collateral or additional specific
        descriptions of certain Collateral delivered to Secured Party in the future
        by
        Debtor. The failure of any of these representations or warranties or any
        description of Collateral therein to be accurate or complete shall not impair
        the Security Interest in any such Collateral.

        COVENANTS.
        So long
        as Lenders are committed to extend credit to Debtor under the Credit Agreement
        and thereafter until the Indebtedness is paid and performed in full, Debtor
        covenants and agrees with Secured Party that Debtor will: 

       

      (a)
        Credit
        Agreement.
        (i)
        Comply with, perform, and be bound by all covenants and agreements in the
        Credit
        Agreement that are applicable to it, its assets, or its operations, each
        of
        which is hereby ratified and confirmed (INCLUDING,
        WITHOUT LIMITATION, THE INDEMNIFICATION AND RELATED PROVISIONS IN
SECTION
        12.03
        OF THE CREDIT AGREEMENT);
        AND
        (ii) CONSENT TO AND APPROVE THE VENUE, SERVICE OF PROCESS, AND WAIVER OF
        JURY
        TRIAL PROVISIONS OF SECTION
        12.13
        OF THE CREDIT AGREEMENT. 

       

      (b)
        Information/Record
        of Collateral.
        Maintain, at the place where Debtor is entitled to receive notices under
        the
        Loan Documents, a current record of where all Collateral is located, permit
        representatives of Secured Party at any time during normal business hours
        to
        inspect and make abstracts from such records, and furnish to Secured Party,
        at
        such intervals as Secured Party may request, such documents, lists,
        descriptions, certificates, and other information as may be necessary or
        proper
        to keep Secured Party informed with respect to the identity, location, status,
        condition, and value of the Collateral. In addition, from time to time at
        the
        request of Secured Party deliver to Secured Party such information regarding
        Debtor as Secured Party may reasonably request.

       

      (c)
        Annexes.
        Immediately update all annexes hereto if any information therein shall become
        inaccurate or incomplete. Notwithstanding any other provision herein, Debtor’s
        failure to describe any Collateral required to be listed on any annex hereto
        shall not impair Secured Party’s Security Interest in the Collateral.

       

      (d)
        Perform
        Indebtedness.
        Fully
        perform all of Debtor’s duties under and in connection with each transaction to
        which the Collateral, or any part thereof, relates, so that the amounts thereof
        shall actually become payable in their entirety to Secured Party. Furthermore,
        notwithstanding anything to the contrary contained herein, (i) Debtor shall
        remain liable under the contracts, agreements, documents, and instruments
        included in the Collateral to the extent set forth therein to perform all
        of its
        duties and obligations thereunder to the same extent as if this Security
        Agreement had not been executed, (ii) the exercise by Secured Party of any
        of
        its rights or remedies hereunder shall not release Debtor from any of its
        duties
        or obligations under the contracts, agreements, documents, and instruments
        included in the Collateral, and (iii) Secured Party shall not have any
        indebtedness, liability, or obligation under any of the contracts, agreements,
        documents, and instruments included in the Collateral by reason of this Security
        Agreement, and Secured Party shall not be obligated to perform any of the
        obligations or duties of Debtor thereunder or to take any action to collect
        or
        enforce any claim for payment assigned hereunder. 

       

      (e)
        Notices.
        (i)
        Except as may be otherwise expressly permitted under the terms of the Credit
        Agreement, promptly notify Secured Party of (A) any change in any fact or
        circumstances represented or warranted by Debtor with respect to any of the
        Collateral or Indebtedness, (B) any claim, action, or proceeding affecting
        title
        to all or any of the Collateral or the Security Interest and, at the request
        of
        Secured Party, appear in and defend, at Debtor’s expense, any such action or
        proceeding, (C) any material change in the nature of the Collateral, (D)
        any
        material damage to or loss of Collateral, and (E) the occurrence of any
other event or condition (including, without limitation,
        matters as to Lien priority) that could have a material adverse effect on
        the
        Collateral (taken as a whole) or the Security Interest created hereunder;
        and
        (ii) give Secured Party thirty (30) days written notice before any proposed
        (A)
        relocation of its principal place of business or chief executive office,
        (B)
        change of its name, identity, or corporate structure, (C) relocation of the
        place where its books and records concerning its accounts are kept, (D)
        relocation of any Collateral (other
        than
        delivery
        of inventory in the ordinary course of business to third party contractors
        for
        processing and sales of inventory in the ordinary course of business or as
        permitted by the Credit Agreement) to a location not described on the attached
        Annex
        A,
        and (E)
        change of its jurisdiction of organization or organizational identification
        number, as applicable. Prior to making any of the changes contemplated in
        clause
        (ii)
        preceding, Debtor shall execute and deliver all such additional documents
        and
        perform all additional acts as Secured Party, in its sole discretion, may
        request in order to continue or maintain the existence and priority of the
        Security Interests in all of the Collateral.

      (f)
        Collateral
        in Trust.
        Hold in
        trust (and not commingle with other assets of Debtor) for Secured Party all
        Collateral that is Collateral Notes or Pledged Securities, at any time received
        by Debtor, and promptly deliver same to Secured Party, unless
        Secured
        Party at its option (which may be evidenced only by a writing signed by Secured
        Party stating that Secured Party elects to permit Debtor to so retain) permits
        Debtor to retain the same, but any Collateral Notes or Pledged Securities,
        so
        retained shall be marked to state that they are assigned to Secured Party;
        each
        such instrument shall be endorsed to the order of Secured Party (but the
        failure
        of same to be so marked or endorsed shall not impair the Security Interest
        thereon). 

       

      (g)
        Control.
        Execute
        all documents and take any action required by Secured Party in order for
        Secured
        Party to obtain “control”
        (as
        defined in the UCC) with respect to Collateral consisting of uncertificated
        Pledged Securities. If Debtor at any time holds or acquires 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, promptly notify Secured Party thereof
        and,
        at the request of Secured Party, take such action as Secured Party may
        reasonably request to vest in Secured Party control under the UCC of such
        electronic chattel paper or control under the federal Electronic
        Signatures in Global and National Commerce Act
        or, as
        the case may be, the Uniform
        Electronic Transactions Act,
        as so
        in effect in such jurisdiction, of such transferable record. 

       

      (h)
        Further
        Assurances.
        At
        Debtor’s expense and Secured Party’s request, before or after a Default or Event
        of Default, (i) file or cause to be filed such applications and take such
        other
        actions as Secured Party may request to obtain the consent or approval of
        any
        Governmental Authority to Secured Party’s rights hereunder, including, without
        limitation, the Right to sell all the Collateral upon a Default or Event
        of
        Default without additional consent or approval from such Governmental Authority
        (and, because Debtor agrees that Secured Party’s remedies at law for failure of
        Debtor to comply with this provision would be inadequate and that such failure
        would not be adequately compensable in damages, Debtor agrees that its covenants
        in this provision may be specifically enforced); (ii) from time to time promptly
        execute and deliver to Secured Party all such other assignments, certificates,
        supplemental documents, and financing statements, and do all other acts or
        things as Secured Party may reasonably request in order to more fully create,
        evidence, perfect, continue, and preserve the priority of the Security Interest
        and to carry out the provisions of this Security Agreement; and (iii) pay
        all
        filing fees in connection with any financing, continuation, or termination
        statement or other instrument with respect to the Security Interests.

        Encumbrances.
        Not
        create, permit, or suffer to exist, and shall defend the Collateral against,
        any
        Lien or other encumbrance on the Collateral, and shall defend Debtor’s rights in
        the Collateral and Secured Party’s Security Interest in, the Collateral against
        the claims and demands of all Persons except those holding or claiming Excepted
        Liens. Debtor shall do nothing to impair the rights of Secured Party in the
        Collateral. 

       

      (j)
        Estoppel
        and Other Agreements and Matters.
        Upon
        the reasonable request of Secured Party, either (i) use commercially reasonable
        efforts to cause the landlord or lessor for each location where any of its
        inventory or equipment is maintained to execute and deliver to Secured Party
        an
        estoppel and subordination agreement in such form as may be reasonably
        acceptable to Secured Party and its counsel, or
        (ii)
        deliver to Secured Party a legal opinion or other evidence (in each case
        that is
        reasonably satisfactory to Secured Party and it counsel) that neither the
        applicable lease nor the laws of the jurisdiction in which that location
        is
        situated provide for contractual, common law, or statutory landlord’s Liens that
        is senior to or pari
        passu
        with the
        Security Interest. 

       

      (k)
        Impairment
        of Collateral.
        Not use
        any of the Collateral, or permit the same to be used, for any unlawful purpose,
        in any manner that is reasonably likely to adversely impair the value or
        usefulness of the Collateral, or in any manner inconsistent with the provisions
        or requirements of any policy of insurance thereon nor affix or install any
        accessories, equipment, or device on the Collateral or on any component thereof
        if such addition will impair the original intended function or use of the
        Collateral or such component. 

       

      (l)
        Collateral
        Notes and Collateral Note Security.
        Without
        the prior written consent of Secured Party not (i) modify or substitute,
        or
        permit the modification or substitution of, any Collateral Note or any document
        evidencing the Collateral Note Security or (ii) release any Collateral Note
        Security unless specifically required by the terms thereof. 

       

      (m)
        Securities.
        Except
        as permitted by the Credit Agreement, not sell, exchange, or otherwise dispose
        of, or grant any option, warrant, or other right with respect to, any of
        the
        Pledged Securities; to the extent any issuer of any Pledged Securities is
        controlled by Debtor and/or its Affiliates, not permit such issuer to issue
        any
        additional shares of stock or other securities in addition to or in substitution
        for the Pledged Securities, except issuances to Debtor on terms acceptable
        to
        Secured Party; pledge hereunder, immediately upon Debtor’s acquisition (directly
        or indirectly) thereof, any and all additional shares of stock or other
        securities of each Subsidiary of Debtor; and take any action necessary,
        required, or requested by Secured Party to allow Secured Party to fully enforce

        Material
        Agreements.
        (i)
        Promptly perform, observe, and otherwise comply with each and every covenant,

      (p)

        In
        accordance with prudent business practices, endeavor to collect or cause
        to be
        collected from each account debtor under its accounts, as and when due, any
        and
        all amounts owing under such accounts. Except in the ordinary course of business
        consistent with prudent business practices and industry standards, without
        the
        prior written consent of Secured Party, Debtor shall not (i) grant any extension
        of time for any payment with respect to any of the accounts, (ii) compromise,
        compound, or settle any of the accounts for less than the full amount thereof,
        (iii) release, in whole or in part, any Person liable for payment of any
        of the
        accounts, (iv) allow any credit or discount for payment with respect to any

      7.
        DEFAULT;
        REMEDIES.
        If an
        Event of Default exists, Secured Party may, at its election (but subject
        to the
        terms and conditions of the Credit Agreement), exercise any and all rights
        available to a secured party under the UCC, in addition to any and all other
        rights afforded by the Loan Documents, at law, in equity, or otherwise,
        including, without limitation, (a) requiring Debtor to assemble all or part
        of
        the Collateral and make it available to Secured Party at a place to be
        designated by Secured Party which is reasonably convenient to Debtor and
        Secured
        Party, (b) surrendering any policies of insurance on all or part of the
        Collateral and receiving and applying the unearned premiums as a credit on
        the
        Indebtedness, (c) applying by appropriate judicial proceedings for appointment
        of a receiver for all or part of the Collateral (and Debtor hereby consents
        to
        any such appointment), and (d) applying to the Indebtedness any cash held
        by
        Secured Party under this Security Agreement, including, without limitation,
        any
        cash in the Cash Collateral Account (defined in Section
        8(h)).

       

      (a)
        Notice.
        Reasonable notification of the time and place of any public sale of the
        Collateral, or reasonable notification of the time after which any private
        sale
        or other intended disposition of the Collateral is to be made, shall be sent
        to
        Debtor and to any other Person entitled to notice under the UCC; provided
        that,
        if any
        of the Collateral threatens to decline speedily in value or is of the type
        customarily sold on a recognized market, Secured Party may sell or otherwise
        dispose of the Collateral without notification, advertisement, or other notice
        of any kind. It is agreed that notice sent or given not less than ten days
        prior
        to the taking of the action to which the notice relates is reasonable
        notification and notice for the purposes of this subparagraph.

      (b)
        Condition
        of Collateral; Warranties.
        Secured
        Party has no obligation to clean-up or otherwise prepare the Collateral for
        sale. Secured Party may sell the Collateral without giving any warranties
        as to
        the Collateral. Secured Party may specifically disclaim any warranties of
        title
        or the like. This procedure will not be considered adversely to affect the
        commercial reasonableness of any sale of the Collateral. 

       

      (c)
        Compliance
        with Other Laws.
        Secured
        Party may comply with any applicable state or federal law requirements in
        connection with a disposition of the Collateral and compliance will not be
        considered to adversely affect the commercial reasonableness of any sale
        of the
        Collateral. 

       

      (d)
        Sales
        of Pledged Securities.
        

       

      (i)
        Debtor agrees that, because of the Securities Act of 1933, as amended, or
        the
        rules and regulations promulgated thereunder (collectively, the “Securities
        Act”),
        or any
        other laws or regulations, and for other reasons, there may be legal or
        practical restrictions or limitations affecting Secured Party in any attempts
        to
        dispose of certain portions of the Pledged Securities and for the enforcement
        of
        its rights. For these reasons, Secured Party is hereby authorized by Debtor,
        but
        not obligated, upon the occurrence and during the continuation of an Event
        of
        Default, to sell all or any part of the Pledged Securities at private sale,
        subject to investment letter or in any other manner which will not require
        the
        Pledged Securities, or any part thereof, to be registered in accordance with
        the
        Securities Act or any other laws or regulations, at a reasonable price at
        such
        private sale or other distribution in the manner mentioned above. Debtor
        understands that Secured Party may in its discretion approach a limited number
        of potential purchasers and that a sale under such circumstances may yield
        a
        lower price for the Pledged Securities, or any part thereof, than would
        otherwise be obtainable if such Collateral were either afforded to a larger
        number or potential purchasers, registered under the Securities Act, or sold
        in
        the open market. Debtor agrees that any such private sale made under this
        Paragraph
        7(d)
        shall be
        deemed to have been made in a commercially reasonable manner, and that Secured
        Party has no obligation to delay the sale of any Pledged Securities to permit
        the issuer thereof to register it for public sale under any applicable federal
        or state securities laws. 

       

      (ii)
        Secured Party is authorized, in connection with any such sale, (A) to restrict
        the prospective bidders on or purchasers of any of the Pledged Securities
        to a
        limited number of sophisticated investors who will represent and agree that
        they
        are purchasing for their own account for investment and not with a view to
        the
        distribution or sale of any of such Pledged Securities, and (B) to impose
        such
        other limitations or conditions in connection with any such sale as Secured
        Party reasonably deems necessary in order to comply with applicable law.
        Debtor
        covenants and agrees that it will execute and deliver such documents and
        take
        such other action as Secured Party reasonably deems necessary in order that
        any
        such sale may be made in compliance with applicable law. Upon any such sale
        Secured Party shall have the right to deliver, assign, and transfer to the
        purchaser thereof the Pledged Securities so sold. Each purchaser at any such
        sale shall hold the Pledged Securities so sold absolutely free from any claim
        or
        right of Debtor of whatsoever kind, including any equity or right of redemption
        of Debtor. Debtor, to the extent permitted by applicable law, hereby
        specifically waives all rights of redemption, stay, or appraisal which it
        has or
        may have under any law now existing or hereafter enacted.

      (iii)
        Debtor agrees that ten days’ written notice from Secured Party to Debtor of
        Secured Party’s intention to make any such public or private sale or sale at a
        broker’s board or on a securities exchange shall constitute reasonable notice
        under the UCC. Such notice shall (A) in case of a public sale, state the
        time
        and place fixed for such sale, (B) in case of sale at a broker’s board or on a
        securities exchange, state the board or exchange at which such a sale is
        to be
        made and the day on which the Pledged Securities, or the portion thereof
        so
        being sold, will first be offered for sale at such board or exchange, and
        (C) in
        the case of a private sale, state the day after which such sale may be
        consummated. Any such public sale shall be held at such time or times within
        ordinary business hours and at such place or places as Secured Party may
        fix in
        the notice of such sale. At any such sale, the Pledged Securities may be
        sold in
        one lot as an entirety or in separate parcels, as Secured Party may reasonably
        determine. Secured Party shall not be obligated to make any such sale pursuant
        to any such notice. Secured Party may, without notice or publication, 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 the sale, and such sale may
        be
        made at any time or place to which the same may be so adjourned. 

       

      (iv)
        In
        case of any sale of all or any part of the Pledged Securities on credit or
        for
        future delivery, the Pledged Securities so sold may be retained by Secured
        Party
        until the selling price is paid by the purchaser thereof, but Secured Party
        shall not incur any liability in case of the failure of such purchaser to
        take
        up and pay for the Pledged Securities so sold and in case of any such failure,
        such Pledged Securities may again be sold upon like notice. Secured Party,
        instead of exercising the power of sale herein conferred upon it, may proceed
        by
        a suit or suits at law or in equity to foreclose the Security Interests and
        sell
        the Pledged Securities, or any portion thereof, under a judgment or decree
        of a
        court or courts of competent jurisdiction. 

       

      (v)
        Without limiting the foregoing, or imposing upon Secured Party any obligations
        or duties not required by applicable law, Debtor acknowledges and agrees
        that,
        in foreclosing upon any of the Pledged Securities, or exercising any other
        rights or remedies provided Secured Party hereunder or under applicable law,
        Secured Party may, but shall not be required to, (A) qualify or restrict
        prospective purchasers of the Pledged Securities by requiring evidence of
        sophistication or creditworthiness, and requiring the execution and delivery
        of
        confidentiality agreements or other documents and agreements as a condition
        to
        such prospective purchasers’ receipt of information regarding the Pledged
        Securities or participation in any public or private foreclosure sale process,
        (B) provide to prospective purchasers business and financial information
        regarding Debtor or the Companies available in the files of Secured Party
        at the
        time of commencing the foreclosure process, without the requirement that
        Secured
        Party obtain, or seek to obtain, any updated business or financial information
        or verify, or certify to prospective purchasers, the accuracy of any such
        business or financial information, or (C) offer for sale and sell the Pledged
        Securities with, or without, first employing an appraiser, investment banker,
        or
        broker with respect to the evaluation of the Pledged Securities, the
        solicitation of purchasers for Pledged Securities, or the manner of sale
        of
        Pledged Securities. 

       

      (e)
        Application
        of Proceeds.
        Secured
        Party shall apply the proceeds of any sale or other disposition of the
        Collateral under this Paragraph
        7
        in the
        following order: first,
        to the
        payment of all expenses incurred in retaking, holding, and preparing any
        of the
        Collateral for sale(s) or other disposition, in arranging for such sale(s)
        or
        other disposition, and in actually selling or disposing of the same (all
        of
        which are part of the Indebtedness); second,
        toward
        repayment of amounts expended by Secured Party under Paragraph
        8;
        and
        third, toward
        payment of the balance of the Indebtedness in the order and manner specified
        in
        the Credit Agreement. Any surplus remaining shall be delivered to Debtor
        or as a
        court of competent jurisdiction may direct. If the proceeds are insufficient
        to
        pay the Indebtedness in full, Debtor shall remain liable for any deficiency.

      (f)
        Sales
        on Credit.
        If
        Secured Party sells any of the Collateral upon credit, Debtor will be credited
        only with payments actually made by the purchaser, received by the Secured
        Party, and applied to the indebtedness of the purchaser. In the event the
        purchaser fails to pay for the Collateral, Secured Party may resell the
        Collateral and Debtor shall be credited with the proceeds of the sale.

       

      8.
        OTHER
        RIGHTS OF SECURED PARTY. 

       

      (a)
        Performance.
        If
        Debtor fails to keep the Collateral in good repair, working order, and
        condition, as required by the Loan Documents, or fails to pay when due all
        Taxes
        on any of the Collateral in the manner required by the Loan Documents, or
        fails
        to preserve the priority of the Security Interest in any of the Collateral,
        or
        fails to keep the Collateral insured as required by the Loan Documents, or
        otherwise fails to perform any of its obligations under the Loan Documents
        with
        respect to the Collateral, then Secured Party may, at its option, but without
        being required to do so, make such repairs, pay such Taxes, prosecute or
        defend
        any suits in relation to the Collateral, or insure and keep insured the
        Collateral in any amount deemed appropriate by Secured Party, or take all
        other
        action which Debtor is required, but has failed or refused, to take under
        the
        Loan Documents. Any sum which may be expended or paid by Secured Party under
        this subparagraph (including, without limitation, court costs and reasonable
        attorneys’ fees) shall bear interest from the dates of expenditure or payment at
        the Post-Default Rate until paid and, together
        with
        such
        interest, shall be payable by Debtor to Secured Party upon demand and shall
        be
        part of the Indebtedness. 

       

      (b)
        Collection.
        If an
        Event of Default exists and upon notice from Secured Party, each Collateral
        Obligor with respect to any payments on any of the Collateral (including,
        without limitation, dividends and other Distributions with respect to the
        Pledged Securities and Partnership Interests, payments on Collateral Notes,
        insurance proceeds payable by reason of loss or damage to any of the Collateral,
        or payments or distributions with respect to Deposit Accounts) is hereby
        authorized and directed by Debtor to make payment directly to Secured Party,
        regardless of whether Debtor was previously making collections thereon. Subject
        to Paragraph
        8(f)
        hereof,
        until such notice is given, Debtor is authorized to retain and expend all
        payments made on Collateral. If an Event of Default exists, Secured Party
        shall
        have the Right in its own name or in the name of Debtor to compromise or
        extend
        time of payment with respect to all or any portion of the Collateral for
        such
        amounts and upon such terms as Secured Party may determine; to demand, collect,
        receive, receipt for, sue for, compound, and give acquittances for any and
        all
        amounts due or to become due with respect to Collateral; to take control
        of cash
        and other proceeds of any Collateral; to endorse the name of Debtor on any
        notes, acceptances, checks, drafts, money orders, or other evidences of payment
        on Collateral that may come into the possession of Secured Party; to sign
        the
        name of Debtor on any invoice or bill of lading relating to any Collateral,
        on
        any drafts against Collateral Obligors or other Persons making payment with
        respect to Collateral, on assignments and verifications of accounts or other
        Collateral and on notices to Collateral Obligors making payment with respect
        to
        Collateral; to send requests for verification of obligations to any Collateral
        Obligor; and to do all other acts and things necessary to carry out the intent
        of this Security Agreement. If an Event of Default exists and any Collateral
        Obligor fails or refuses to make payment on any Collateral when due, Secured Party is authorized, in its sole
        discretion, either in
        its own name or in the name of Debtor, to take such action as Secured Party
        shall deem appropriate for the collection of any amounts owed with respect
        to
        Collateral or upon which a delinquency exists. Regardless of any other provision
        hereof, however, Secured Party shall never be liable for its failure to collect,
        or for its failure to exercise diligence in the collection of, any amounts
        owed
        with respect to Collateral, nor shall it be under any duty whatsoever to
        anyone
except
        Debtor
        to account for funds that it shall actually receive hereunder. Without limiting
        the generality of the foregoing, Secured Party shall have no responsibility
        for
        ascertaining any maturities, calls, conversions, exchanges, offers, tenders,
        or
        similar matters relating to any Collateral, or for informing Debtor with
        respect
        to any of such matters (irrespective of whether Secured Party actually has,
        or
        may be deemed to have, knowledge thereof). The receipt of Secured Party to
        any
        Collateral Obligor shall be a full and complete release, discharge, and
        acquittance to such Collateral Obligor, to the extent of any amount so paid
        to
        Secured Party.

        Proprietary
        Rights.
        For
        purposes of enabling Secured Party to exercise its rights and remedies under
        this Security Agreement and enabling Secured Party and its successors and
        assigns to enjoy the full benefits of the Collateral, Debtor hereby grants
        to
        Secured Party an irrevocable, nonexclusive license (exercisable without payment
        of royalty or other compensation to Debtor) to make, have made, use, sell,
        import, reproduce, distribute, display and perform publicly, create derivative
        works, perform by means of digital transmission, license, or sublicense any
        of
        the Proprietary Rights. Debtor shall provide Secured Party with reasonable
        access to all media in which any of the Proprietary Rights may be recorded
        or
        stored and all computer programs used for the completion or printout thereof.
        This license shall also inure to the benefit of all successors, assigns,
        and
        transferees of Secured Party. Upon the occurrence of a Event of Default,
        Secured
        Party may require that Debtor assign all of its right, title, and interest
        in
        and to the Proprietary Rights or any part thereof to Secured Party or such
        other
        Person as Secured Party may designate pursuant to documents satisfactory
        to
        Secured Party. If no Default or Event of Default exists, Debtor shall have
        the
        exclusive, non-transferable right and license to use the Proprietary Rights
        in
        the ordinary course of business and the exclusive right to grant to other
        Persons licenses and sublicenses with respect to the Proprietary Rights for
        full
        and fair consideration. 

       

      (d)
        Record
        Ownership of Securities.
        If a
        Default or Event of Default exists, Secured Party at any time may have any
        Collateral that is Pledged Securities and that is in the possession of Secured
        Party, or its nominee or nominees, registered in its name, or in the name
        of its
        nominee or nominees, as Secured Party; and, as to any Collateral that is
        Pledged
        Securities so registered, Secured Party shall execute and deliver (or cause
        to
        be executed and delivered) to Debtor all such proxies, powers of attorney,
        dividend coupons or orders, and other documents as Debtor may reasonably
        request
        for the purpose of enabling Debtor to exercise the voting rights and powers
        which it is entitled to exercise under this Security Agreement or to receive
        the
        dividends and other Distributions and payments in respect of such Collateral
        that is Pledged Securities or proceeds thereof which it is authorized to
        receive
        and retain under this Security Agreement. 

       

      (e)
        Voting
        of Securities.
        As long
        as no Default exists, Debtor is entitled to exercise all voting rights
        pertaining to any Pledged Securities and Partnership Interests; provided,
        however,
        that no
        vote shall be cast or consent, waiver, or ratification given or action taken
        without the prior written consent of Secured Party which would (x) be
        inconsistent with or violate any provision of this Security Agreement or
        any
        other Loan Document or (y) amend, modify, or waive any term, provision or
        condition of the certificate of incorporation, bylaws, certificate of formation,
        or other charter document, or other agreement relating to, evidencing, providing
        for the issuance of, or securing any Collateral; and provided
        further
        that
        Debtor shall give Secured Party at least five Business Days’
prior written notice in the form of an officers’ certificate of the manner in
        which it intends to exercise, or the reasons for refraining from exercising,
        any
        voting or other consensual rights pertaining to the Collateral or any part
        thereof which might have a material adverse effect on the value of the
        Collateral or any part thereof. If an Event of Default exists and if Secured
        Party elects to exercise such right, the right to vote any Pledged Securities
        shall be vested exclusively in Secured Party. To this end, Debtor hereby
        irrevocably constitutes and appoints Secured Party the proxy and
        attorney-in-fact of Debtor, with full power of substitution, to vote, and
        to act
        with respect to, any and all Collateral that is Pledged Securities standing
        in
        the name of Debtor or with respect to which Debtor is entitled to vote and
        act,
        subject to the understanding that such proxy may not be exercised unless
        an
        Event of Default exists. The proxy herein granted is coupled with an interest,
        is irrevocable, and shall continue until the Indebtedness has been paid and
        performed in full.

        Certain
        Proceeds.
        Notwithstanding any contrary provision herein, any and all 

       

      (i)
        dividends, interest, or other Distributions paid or payable other than in
        cash
        in respect of, and instruments and other property received, receivable, or
        otherwise distributed in respect of, or in exchange for, any Collateral;
        

       

      (ii)
        dividends, interest, or other Distributions hereafter paid or payable in
        cash in
        respect of any Collateral in connection with a partial or total liquidation
        or
        dissolution, or in connection with a reduction of capital, capital surplus,
        or
        paid-in-surplus; 

       

      (iii)
        cash paid, payable, or otherwise distributed in redemption of, or in exchange
        for, any Collateral; and 

       

      (iv)
        dividends, interest, or other Distributions paid or payable in violation
        of the
        Loan Documents, 

       

      shall
        be
        part of the Collateral hereunder, and shall, if received by Debtor, be held
        in
        trust for the benefit of Secured Party, and shall forthwith be delivered
        to
        Secured Party (accompanied by proper instruments of assignment and/or stock
        and/or bond powers executed by Debtor in accordance with Secured Party’s
        instructions) to be held subject to the terms of this Security Agreement.
        Any
        cash proceeds of Collateral which come into the possession of Secured Party
        on
        and after the occurrence of an Event of Default (including, without limitation,
        insurance proceeds) may, at Secured Party’s option, be applied in whole or in
        part to the Indebtedness (to the extent then due), be released in whole or
        in
        part to or on the written instructions of Debtor for any general or specific
        purpose, or be retained in whole or in part by Secured Party as additional
        Collateral. Any cash Collateral in the possession of Secured Party may be
        invested by Secured Party in certificates of deposit issued by Secured Party
        (if
        Secured Party issues such certificates) or by any state or national bank
        having
        combined capital and surplus greater than $100,000,000 with a rating from
        Moody’s and S&P of P-1
        and
A-1+,
        respectively, or in securities issued or guaranteed by the United States
        of
        America or any agency thereof. Secured Party shall never be obligated to
        make
        any such investment and shall never have any liability to Debtor for any
        loss
        which may result therefrom. All interest and other amounts earned from any
        investment of Collateral may be dealt with by Secured Party in the same manner
        as other cash Collateral. The provisions of this subparagraph are applicable
        whether or not a Default or Event of Default exists.

      (g)
        Use
        and Operation of Collateral.
        Should
        any Collateral come into the possession of Secured Party, Secured Party may
        use
        or operate such Collateral for the purpose of preserving it or its value
        pursuant to the order of a court of appropriate jurisdiction or in accordance
        with any other rights held by Secured Party in respect of such Collateral.
        Debtor covenants to promptly reimburse and pay to Secured Party, at Secured
        Party’s request, the amount of all reasonable expenses (including, without
        limitation, the cost of any insurance and payment of Taxes or other charges)
        incurred by Secured Party in connection with its custody and preservation
        of
        Collateral, and all such expenses, costs, Taxes, and other charges shall
        bear
        interest at the Post-Default Rate until repaid and, together
        with
        such
        interest, shall be payable by Debtor to Secured Party upon demand and shall
        become part of the Indebtedness. However, the risk of accidental loss or
        damage
        to, or diminution in value of, Collateral is on Debtor, and Secured Party
        shall
        have no liability whatever for failure to obtain or maintain insurance, nor
        to
        determine whether any insurance ever in force is adequate as to amount or
        as to
        the risks insured. With respect to Collateral that is in the possession of
        Secured Party, Secured Party shall have no duty to fix or preserve rights
        against prior parties to such Collateral and shall never be liable for any
        failure to use diligence to collect any amount payable in respect of such
        Collateral, but shall be liable only to account to Debtor for what it may
        actually collect or receive thereon. The provisions of this subparagraph
        are
        applicable whether or not an Event of Default exists. 

       

      (h)
        Power
        of Attorney.
        Debtor
        hereby irrevocably constitutes and appoints Secured Party and any officer
        or
        agent thereof, with full power of substitution, as its true and lawful
        attorney-in-fact with full irrevocable power and authority in the name of
        Debtor
        or in its own name, to take after the occurrence and during the continuance
        of
        an Event of Default and from time to time thereafter, any and all action
        and to
        execute any and all documents and instruments which Secured Party at any
        time
        and from time to time deems necessary or desirable to accomplish the purposes
        of
        this Security Agreement and, without limiting the generality of the foregoing,
        Debtor hereby gives Secured Party the power and right on behalf of Debtor
        and in
        its own name to do any of the following after the occurrence and during the
        continuance of an Event of Default and from time to time thereafter, without
        notice to or the consent of Debtor:

        name,

        in
        exchange for any of the Collateral and, in connection therewith, endorse
        checks,
        notes, drafts, acceptances, money orders, documents of title or any other
        instruments for the payment of money under the Collateral or any policy of
        insurance; 

       

      (iii)
        to
        pay or discharge taxes, Liens, or other encumbrances levied or placed on
        or
        threatened against the Collateral; 

       

      (iv)
        to
        notify post office authorities to change the address for delivery of Debtor
        to
        an address designated by Secured Party and to receive, open, and dispose
        of mail
        addressed to Debtor; and

      (v)
        (A)
        to direct account debtors and any other parties liable for any payment under
        any
        of the Collateral to make payment of any and all monies due and to become
        due
        thereunder directly to Secured Party or as Secured Party shall direct; (B)
        to
        receive payment of and receipt for any and all monies, claims, and other
        amounts
        due and to become due at any time in respect of or arising out of any
        Collateral; (C) to sign and endorse any invoices, freight or express bills,
        bills of lading, storage or warehouse receipts, drafts against debtors,
        assignments, proxies, stock powers, verifications, and notices in connection
        with accounts and other documents relating to the Collateral; (D) to commence
        and prosecute any suit, action, or proceeding at law or in equity in any
        court
        of competent jurisdiction to collect the Collateral or any part thereof and
        to
        enforce any other right in respect of any Collateral; (E) to defend any suit,
        action, or proceeding brought against Debtor with respect to any Collateral;
        (F)
        to settle, compromise, or adjust any suit, action, or proceeding described
        above
        and, in connection therewith, to give such discharges or releases as Secured
        Party may deem appropriate; (G) to exchange any of the Collateral for other
        property upon any merger, consolidation, reorganization, recapitalization,
        or
        other readjustment of the issuer thereof and, in connection therewith, deposit
        any of the Collateral with any committee, depositary, transfer agent, registrar,
        or other designated agency upon such terms as Secured Party may determine;
        (H)
        to add or release any guarantor, indorser, surety, or other party to any
        of the
        Collateral; (I) to renew, extend, or otherwise change the terms and conditions
        of any of the Collateral; (J) to make, settle, compromise or adjust any claims
        under or pertaining to any of the Collateral (including claims under any
        policy
        of insurance); (K) to execute on behalf of Debtor any financing statements
        or
        continuation statements with respect to the Security Interests created hereby,
        and to do any and all acts and things to protect and preserve the Collateral,
        including, without limitation, the protection and prosecution of all rights
        included in the Collateral; and (L) 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 Secured Party were the absolute owner thereof for
        all
        purposes, and to do, at Secured Party’s option and Debtor’s expense, at any
        time, or from time to time, all acts and things which Secured Party deems
        necessary to protect, preserve, maintain, or realize upon the Collateral
        and
        Secured Party’s security interest therein. 

       

      This
        power of attorney is a power coupled with an interest and shall be irrevocable.
        Secured Party 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 Secured Party in this Security Agreement, and shall not be liable for
        any
        failure to do so or any delay in doing so. Neither Secured Party nor any
        Person
        designated by Secured Party shall be liable for any act or omission or for
        any
        error of judgment or any mistake of fact or law. This power of attorney is
        conferred on Secured Party solely to protect, preserve, maintain, and realize
        upon its Security Interest in the Collateral. Secured Party 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.

       

      (i)
        Purchase
        Money Collateral.
        To the
        extent that Secured Party or any Lender has advanced or will advance funds
        to or
        for the account of Debtor to enable Debtor to purchase or otherwise acquire
        rights in Collateral, Secured Party or such Lender, at its option, may pay
        such
        funds (i) directly to the Person from whom Debtor will make such purchase
        or
        acquire such rights, or (ii) to Debtor, in which case Debtor covenants to
        promptly pay the same to such Person, and forthwith furnish to Secured Party
        evidence satisfactory to Secured Party that such payment has been made from
        the
        funds so provided. 

       

      (j)
        Subrogation.
        If any
        of the Indebtedness is given in renewal or extension or applied toward the
        payment of indebtedness secured by any Lien, Secured Party shall be, and
        is
        hereby, subrogated to all of the rights, titles, interests, and Liens securing
        the indebtedness so renewed, extended, or paid.

      (k)
        Indemnification.
        Debtor
        hereby assumes all liability for the Collateral, for the Security Interest,
        and
        for any use, possession, maintenance, and management of, all or any of the
        Collateral, including, without limitation, any Taxes arising as a result
        of, or
        in connection with, the transactions contemplated herein, and agrees to assume
        liability for, and to indemnify and hold Secured Party and each Lender harmless
        from and against, any and all claims, causes of action, or liability, for
        injuries to or deaths of Persons and damage to property, howsoever arising
        from
        or incident to such use, possession, maintenance, and management, whether
        such
        Persons be agents or employees of Debtor or of third parties, or such damage
        be
        to property of Debtor or of others. Debtor agrees to indemnify, save, and
        hold
        Secured Party and each Lender harmless from and against, and covenants to
        defend
        Secured Party and each Lender against, any and all losses, damages, claims,
        costs, penalties, liabilities, and expenses (collectively, “Claims”),
        including, without limitation, court costs and attorneys’ fees, AND
        ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF SECURED PARTY OR ANY
        LENDER,
        OR ANY OF THEIR RESPECTIVE OFFICERS, EMPLOYEES, AGENTS, ADVISORS, EMPLOYEES,
        OR
        REPRESENTATIVES,
        howsoever arising or incurred because of, incident to, or with respect to
        Collateral or any use, possession, maintenance, or management thereof;
provided,
        however,
        that the
        indemnity set forth in this Paragraph
        8(l)
        will not
        apply to Claims caused by the gross negligence or willful misconduct of Secured
        Party or any Lender. 

       

      (l)
        Continuing
        Liability.
        Notwithstanding anything to the contrary contained in this Security Agreement,
        (i) Debtor shall remain liable under the contracts, agreements, documents,
        and
        instruments included in the Collateral to the extent set forth therein to
        perform all of its duties and obligation thereunder to the same extent as
        if
        this Security Agreement had not been executed, (ii) the exercise by Secured
        Party of any of its rights or remedies hereunder shall not release Debtor
        from
        any of its duties or obligations under the contracts, agreements, documents,
        and
        instruments included in the Collateral, and (iii) Secured Party shall not
        have
        any indebtedness, liability, or obligation under any of the contracts,
        agreements, documents, and instruments included in the Collateral by reason
        of
        this Security Agreement, and Secured Party shall not be obligated to perform
        any
        of the obligations or duties of Debtor thereunder or to take any action to
        collect or enforce any claim for payment assigned hereunder.

        MISCELLANEOUS. 

       

      (a)
        Continuing
        Security Interest.
        This
        Security Agreement creates a continuing security interest in the Collateral
        and
        shall (i) remain in full force and effect until the termination of the
        obligations of Lenders to advance Borrowings or issue Letters of Credit under
        the Loan Documents, the payment in full of the Indebtedness, and the expiration
        of all Letters of Credit and all Hedging Agreements issued by any Lender
        or any
        Affiliate of any Lender to any Obligor; and (ii) inure to the benefit of
        and be
        enforceable by Secured Party, Lenders, and their respective successors,
        transferees, and assigns. Without limiting the generality of the foregoing
        clause
        (ii),
        Secured
        Party and Lenders may assign or otherwise transfer any of their respective
        rights under this Security Agreement to any other Person in accordance with
        the
        terms and provisions of Section
        12.06
        of the
        Credit Agreement, and to the extent of such assignment or transfer such Person
        shall thereupon become vested with all the rights and benefits in respect
        thereof granted herein or otherwise to Secured Party or Lenders, as the case
        may
        be. Upon payment in full of the Indebtedness, the termination of the commitment
        of Lenders to extend credit or issue Letters of Credit under the Loan Documents,
        and the expiration and termination of all Letters of Credit and Hedging
        Agreements issued by any Lender or any Affiliate of any Lender to any Obligor,
        Debtor shall be entitled to the return, upon its request and at its expense,
        of
        such of the Collateral as shall not have been sold or otherwise applied pursuant
        to the terms hereof.

      (b)
        Reference
        to Miscellaneous Provisions.
        This
        Security Agreement is one of the “Loan
        Documents”
        referred
        to in the Credit Agreement, and all provisions relating to Loan Documents
        set
        forth in Section
        12
        of the
        Credit Agreement, other than the provisions relating to governing law, are
        incorporated herein by reference, the same as if set forth herein verbatim.
        

       

      (c)
        Term.
        Upon
        the later of (i) the termination of Lenders’ commitments to fund Loans and issue
        Letters of Credit under the Credit Agreement and (ii) the full and final
        payment
        and performance of the Indebtedness (including expiration of any Hedging
        Agreements between Debtor and by Lender or its Affiliate), this Security
        Agreement shall thereafter terminate upon receipt by Secured Party of Debtor’s
        written notice of such termination; provided
        that
        no
        Collateral Obligor, if any, on any of the Collateral shall ever be obligated
        to
        make inquiry as to the termination of this Security Agreement, but shall
        be
        fully protected in making payment directly to Secured Party until actual
        notice
        of such total payment of the Indebtedness is received by such Collateral
        Obligor. 

       

      (d)
        Actions
        Not Releases.
        The
        Security Interest and Debtor’s obligations and Secured Party’s rights hereunder
        shall not be released, diminished, impaired, or adversely affected by the
        occurrence of any one or more of the following events: (i) the taking or
        accepting of any other security or assurance for any or all of the Indebtedness;
        (ii) any release, surrender, exchange, subordination, or loss of any security
        or
        assurance at any time existing in connection with any or all of the
        Indebtedness; (iii) the modification of, amendment to, or waiver of compliance
        with any terms of any of the other Loan Documents without the notification
        or
        consent of Debtor, except
        as
        required therein (the right to such notification or consent being herein
        specifically waived by Debtor); (iv) the insolvency, bankruptcy, or lack
        of
        corporate or trust power of any party at any time liable for the payment
        of any
        or all of the Indebtedness, whether now existing or hereafter occurring;
        (v) any
        renewal, extension, or rearrangement of the payment of any or all of the
        Indebtedness, either with or without notice to or consent of Debtor, or any
        adjustment, indulgence, forbearance, or compromise that may be granted or
        given
        by Secured Party or any Lender to Debtor; (vi) any neglect, delay, omission,
        failure, or refusal of Secured Party or any Lender to take or prosecute any
        action in connection with any other agreement, document, guaranty, or instrument
        evidencing, securing, or assuring the payment of all or any of the Indebtedness;
        (vii) any failure of Secured Party or any Lender to notify Debtor of any
        renewal, extension, or assignment of the Indebtedness or any part thereof,
        or
        the release of any Collateral or other security, or of any other action taken
        or
        refrained from being taken by Secured Party or any Lender against Debtor
        or any
        new agreement between or among Secured Party or one or more Lenders and Debtor,
        it
        being understood that
        except
        as expressly provided herein, neither Secured Party nor any Lender shall
        be
        required to give Debtor any notice of any kind under any circumstances
        whatsoever with respect to or in connection with the Indebtedness, including,
        without limitation, notice of acceptance of this Security Agreement or any
        Collateral ever delivered to or for the account of Secured Party hereunder;
        (viii) the illegality, invalidity, or unenforceability of all or any part
        of the
        Indebtedness against any party obligated with respect thereto by reason of
        the
        fact that the Indebtedness, or the interest paid or payable with respect
        thereto, exceeds the amount permitted by law, the act of creating the
        Indebtedness, or any part thereof, is ultra
        vires,
        or the
        officers, partners, or trustees creating same acted in excess of their
        authority, or for any other reason; or (ix) if any payment by any party
        obligated with respect thereto is held to constitute a preference under
        applicable laws or for any other reason Secured Party or any Lender is required
        to refund such payment or pay the amount thereof to someone else. 

       

      (e)
        Waivers.
        Except
        to the
        extent expressly otherwise provided herein or in other Loan Documents and
        to the
        fullest extent permitted by applicable law, Debtor waives (i) any right to
        require Secured Party or any Lender to proceed against any other Person,
        to
        exhaust its rights in Collateral, or to pursue any other right which Secured
        Party or any Lender may have; (ii) with respect to the Indebtedness, presentment
        and demand for payment, protest, notice of protest and nonpayment, and notice
        of
        the intention to accelerate; and (iii) all rights of marshaling in respect
        of
        any and all of the Collateral.

      (f)
        Financing
        Statement; Authorization.
        Secured
        Party shall be entitled at any time to file this Security Agreement or a
        carbon,
        photographic, or other reproduction of this Security Agreement, as a financing
        statement, but the failure of Secured Party to do so shall not impair the
        validity or enforceability of this Security Agreement. Debtor hereby irrevocably
        authorizes Secured Party at any time and from time to time to file in any
        UCC
        jurisdiction any initial financing statements and amendments thereto (without
        the requirement for Debtor’s signature thereon) that (i) describe the Collateral
        (A) as “all assets of Debtor” or words of similar effect, regardless of whether
        any particular asset comprised in the Collateral falls within the scope of
        Article 9 of the UCC of the state or such jurisdiction or whether such assets
        are included in the Collateral hereunder, or (B) as being of an equal or
        lesser
        scope or with greater detail, and (ii) contain any other information required
        by
        Article 9 of the UCC of the state or such jurisdiction for the sufficiency
        or
        filing office acceptance of any financing statement or amendment, including
        whether the Debtor is an organization, the type of organization, and any
        organization identification number issued to Debtor. Debtor agrees to furnish
        any such information to Secured Party promptly upon request. 

       

      (g)
        Amendments.
        This
        Security Agreement may be amended only by an instrument in writing executed
        jointly by Debtor and Secured Party, and supplemented only by documents
        delivered or to be delivered in accordance with the express terms hereof.
        

       

      (h)
        Multiple
        Counterparts.
        This
        Security Agreement has been executed in a number of identical counterparts,
        each
        of which shall be deemed an original for all purposes and all of which
        constitute, collectively, one agreement; but, in making proof of this Security
        Agreement, it shall not be necessary to produce or account for more than
        one
        such counterpart. Signatures transmitted by facsimile shall be binding and
        deemed original until such original signatures are received from the parties
        hereto by the Secured Party. 

       

      (i)
        Parties
        Bound; Assignment.
        This
        Security Agreement shall be binding on Debtor and Debtor’s heirs, legal
        representatives, successors, and assigns and shall inure to the benefit of
        Secured Party and Secured Party’s successors and assigns.

       

      (i)
        Secured Party is the administrative agent for each Lender under the Credit
        Agreement, the Security Interest and all rights granted to Secured Party
        hereunder or in connection herewith are for the ratable benefit of each Lender,
        and Secured Party may, without the joinder of any Lender, exercise any and
        all
        rights in favor of Secured Party or Lenders hereunder, including, without
        limitation, conducting any foreclosure sales hereunder, and executing full
        or
        partial releases hereof, amendments or modifications hereto, or consents
        or
        waivers hereunder. The rights of each Lender vis-a-vis
        Secured
        Party and each other Lender may be subject to one or more separate agreements
        between or among such parties, but Debtor need not inquire about any such
        agreement or be subject to any terms thereof unless
        Debtor
        specifically joins therein; and consequently, neither Debtor nor Debtor’s heirs,
        personal representatives, successors, and assigns shall be entitled to any
        benefits or provisions of any such separate agreements or be entitled to
        rely
        upon or raise as a defense, in any manner whatsoever, the failure or refusal
        of
        any party thereto to comply with the provisions thereof.

      Borrower and the Guarantors;  

     

    WHEREAS,
      as a condition precedent to extending credit to the Borrower pursuant to the

      under this Guaranty Agreement, (iii) it is otherwise solvent and (iv) the
      execution and delivery of this Guaranty Agreement and the consummation of the
      transactions contemplated hereby will not render it insolvent;

    GUARANTY
      PROVISIONS

     

    SECTION
      2.1 Guaranty
      Agreement.
      The
      Guarantor hereby absolutely, unconditionally, and irrevocably (1) guarantees
      the
      full and punctual payment when due, whether at stated maturity, by required
      prepayment, declaration, acceleration, demand or otherwise, of all Indebtedness
      of the Borrower and each other Obligor now or hereafter existing under each
      of
      the Credit Agreement, the Notes and each other Loan Document to which the
      Borrower or such other Obligor is or may become a party, whether for principal,
      interest, fees, expenses or otherwise (including all such amounts which would
      become due but for the operation of the automatic stay under Section 362(a)
      of
      the United States Bankruptcy Code, 11 U.S.C. §362(a), and the operation of
      Sections 502(b) and 506(b) of the United States Bankruptcy Code, 11 U.S.C.
      §502(b) and §506(b)), and (2) indemnifies and holds harmless each Lender and
      each holder of a Note for any and all costs and expenses (including reasonable
      attorney’s fees and expenses) incurred by such Lender or such holder, as the
      case may be, in enforcing any rights under this Guaranty Agreement; provided,
      however,
      that
      the Guarantor shall be liable under this Guaranty Agreement for the maximum
      amount of such liability that can be hereby incurred without rendering this
      Guaranty Agreement, as it relates
      to the Guarantor, voidable under applicable law relating to fraudulent
      conveyance or fraudulent transfer, and not for any greater amount. This Guaranty
      Agreement constitutes a guaranty of payment when due and not of collection,
      and
      the Guarantor specifically agrees that it shall not be necessary or required
      that any Lender or any holder of any Note exercise any right, assert any claim
      or demand or enforce any remedy whatsoever against the Borrower or any other
      Obligor (or any other Person) before or as a condition to the obligations of
      the
      Guarantor hereunder.  

     

    

       

    

    SECTION
      2.2 Acceleration
      of Guaranty Agreement.
      The
      Guarantor agrees that, in the event of the occurrence of any event of the type
      described in Section
      10.01(e), (f) or (g)
      of the
      Credit Agreement, with respect to the Borrower, any other Obligor or the
      Guarantor, and if such event shall occur at a time when any of the Indebtedness
      may not then be due and payable by the Borrower due to any automatic stay or
      other debtor relief laws, the Guarantor will pay to the Lenders forthwith the
      full amount which would be payable hereunder by the Guarantor if all such
      Indebtedness were then due and payable.  

     

SECTION
  2.3 Guaranty Agreement Absolute, etc. This Guaranty Agreement
  shall in all respects be a continuing, absolute, unconditional and irrevocable
  guaranty of payment, and shall remain in full force and effect until all Indebtedness
  of the Borrower and each other Obligor has been paid in full, all obligations
  of the Guarantor hereunder shall have been paid in full, all Commitments shall
  have terminated and all Lender Hedging Agreements have terminated. Guarantor
  may not rescind or revoke its obligations hereunder. The Guarantor guarantees
  that the Indebtedness of the Borrower and each other Obligor will be paid strictly
  in accordance with the terms of the Credit Agreement and each other Loan Document
  under which they arise, regardless of any law, regulation or order now or hereafter
  in effect in any jurisdiction affecting any of such terms or the rights of any
  Lender or any holder of any Note with respect thereto. The liability of the
  Guarantor under this Guaranty Agreement shall be absolute, unconditional and
  irrevocable irrespective of: (1) any lack of validity, legality or enforceability
  of the Credit Agreement, any Note or any other Loan Document; (2) the failure
  of any Lender or any holder of any Note (a) to assert any claim or demand or
  to enforce any right or remedy against the Borrower, any other Obligor or any
  other Person (including any other guarantor) under the provisions of the Credit
  Agreement, any Note, any other Loan Document or otherwise, or (b) to exercise
  any right or remedy against any other guarantor of, or collateral securing,
  any Indebtedness of the Borrower or any other Obligor; (3) any change in the
  time, manner or place of payment of, or in any other term of, all or any of
  the Indebtedness of the Borrower or any other Obligor, or any other extension,
  compromise or renewal of any Indebtedness of the Borrower or any other Obligor;
  (4) any reduction, limitation, impairment or termination of any Indebtedness
  of the Borrower or any other Obligor for any reason, including any claim of
  waiver, release, surrender, alteration or compromise, and shall not be subject
  to (and the Guarantor hereby waives any right to or claim of) any defense or
  setoff, counterclaim, recoupment or termination whatsoever by reason of the
  invalidity, illegality, nongenuineness, irregularity, compromise, unenforceability
  of, or any other event or occurrence affecting, any Indebtedness of the Borrower,
  any other Obligor or otherwise; (5) any amendment to, rescission, waiver, or
  other modification of, or any consent to departure from, any of the terms of
  the Credit Agreement, any Note or any other Loan Document; (6) any addition,
  exchange, release, surrender or non-perfection of any collateral, or any amendment
  to or waiver or release or addition of, or consent to departure from, any other
  guaranty, held by any Lender or any holder of any Note securing any of the Indebtedness
  of the Borrower or any other Obligor; (7) the insolvency or bankruptcy of, or
  similar event affecting, the Borrower or any other Obligor; or (8) any other
  circumstance which might otherwise constitute a defense available to, or a legal
  or equitable discharge of, the Borrower, any other Obligor, any surety or any
  guarantor. Guarantor waives all rights and defenses which may arise with respect
  to any of the foregoing, and Guarantor waives any right to revoke this Guaranty
  Agreement with respect to future indebtedness. Guarantor waives all rights or
  defenses under (1) Section 34.01 et seq. of the Texas Business
  and Commerce Code, as amended, (2) Section 17.001 of the Texas Civil
  Practice and Remedies Code, as amended, (3) Rule 31 of the Texas Rules
  of Civil Procedure, as amended, or (4) common law, in equity, under contract,
  by statute, or otherwise.  

    
       

    

    

    SECTION
      2.4 Reinstatement.
      The
      Guarantor agrees that this Guaranty Agreement shall continue to be effective
      or
      be reinstated, as the case may be, if at any time any payment (in whole or
      in
      part) of any of the Indebtedness is rescinded or must otherwise be restored
      by
      any Lender or any holder of any Note, upon the insolvency, bankruptcy or
      reorganization of the Borrower, any other Obligor or otherwise, all as though
      such payment had not been made.  

     

    SECTION
      2.5 Waiver,
      etc.
      The
      Guarantor hereby waives promptness, diligence, notice of acceptance and any
      other notice with respect to any of the Indebtedness of the Borrower or any
      other Obligor and this Guaranty Agreement and any requirement that the
      Administrative Agent, any other Lender or any holder of any Note protect,
      secure, perfect or insure any security interest or Lien, or any property subject
      thereto, or exhaust any right or take any action against the Borrower, any
      other
      Obligor or any other Person (including any other guarantor) or entity or any
      collateral securing the Indebtedness of the Borrower or any other Obligor,
      as
      the case may be.  

     

    SECTION
      2.6 Waiver
      of Subrogation.
      Until
      the Indebtedness is paid in full, all Commitments have terminated and all Lender
      Hedging Agreements have terminated, the Guarantor shall not enforce or exercise
      any claim or other rights which it may now or hereafter acquire against the
      Borrower or any other Obligor that arise from the existence, payment,
      performance or enforcement of the Guarantor’s obligations under this Guaranty
      Agreement or any other Loan Document, including any right of subrogation,
      reimbursement, exoneration, or indemnification, any right to participate in
      any
      claim or remedy of the Lenders against the Borrower or any other Obligor or
      any
      collateral which the Administrative Agent now has or hereafter acquires, whether
      or not such claim, remedy or right arises in equity, or under contract, statute
      or common law, including the right to take or receive from the Borrower or
      any
      other Obligor, directly or indirectly, in cash or other property or by set-off
      or in any manner, payment or security on account of such claim or other rights.
      If any amount shall be paid to the Guarantor in violation of the preceding
      sentence, such amount shall be deemed to have been paid to the Guarantor for
      the
      benefit of, and held in trust for, the Lenders, and shall forthwith be paid
      to
      the Lenders to be credited and applied upon the Indebtedness, whether matured
      or
      unmatured. The Guarantor acknowledges that it will receive direct and indirect
      benefits from the financing arrangements contemplated by the Credit Agreement
      and that the waiver set forth in this Section is knowingly made in contemplation
      of such benefits.  

     

    SECTION
      2.7 Payments
      Free and Clear of Taxes, etc.
      The
      Guarantor hereby agrees that:  

     

    (a)
      All
      payments by the Guarantor hereunder shall be made in accordance with
Section
      4.06
      of the
      Credit Agreement free and clear of and without deduction for any present or
      future income, excise, stamp or franchise taxes and other taxes, fees, duties,
      withholdings or other charges of any nature whatsoever imposed by any taxing
      authority, but excluding franchise taxes and taxes imposed on or measured by
      any
      Lender’s net income or receipts (such non-excluded items being called
“Taxes”).
      In
      the event that any withholding or deduction from any payment to be made by
      the
      Guarantor hereunder is required in respect of any Taxes pursuant to any
      applicable law, rule or regulation, then the Guarantor will (i) pay directly
      to
      the relevant authority the full amount required to be so withheld or deducted;
      (ii) promptly forward to such Lender an official receipt or other documentation
      satisfactory to such Lender evidencing such payment to such authority; and
      (iii)
      pay to such Lender such additional amount or amounts as is necessary to ensure
      that the net amount actually received by such Lender will equal the full amount
      such Lender would have received had no such withholding or deduction been
      required. Moreover, if any Taxes are directly asserted against any Lender with
      respect to any payment received by such Lender hereunder, such Lender may pay
      such Taxes and the Guarantor will promptly pay such additional amounts
      (including, if incurred as a result of Guarantor’s or the Borrower’s action,
      omission or delay, any penalties, interest or expenses) as is necessary in
      order
      that the net amount received by such Lender after the payment of such Taxes
      (including any Taxes on such additional amount) shall equal the amount such
      Lender would have received had such Taxes not been asserted.  

     

    

       

    

    (b)
      If
      the Guarantor fails to pay any Taxes when due to the appropriate taxing
      authority or fails to remit to any Lender the required receipts or other
      required documentary evidence, the Guarantor shall indemnify such Lender for
      any
      incremental Taxes, interest or penalties that may become payable by such Lender
      as a result of any such failure.  

     

    (c)
      Without prejudice to the survival of any other agreement of the Guarantor
      hereunder, the agreements and obligations of the Guarantor contained in this
      Section
      2.7
      shall
      survive the payment in full of the principal of and interest on the Loans.
       

     

    SECTION
      2.8 Contribution
      Agreement.
      Upon
      full and final payment of the Indebtedness, Guarantor and all other Guarantors
      which have made payments upon all or any part of the Indebtedness shall be
      entitled to contribution from all of the other Guarantors, to the end that
      all
      such payments upon the Indebtedness shall be shared among all Guarantors who
      guaranteed such Indebtedness in proportion to their respective Net Worths
      (defined below), provided that the contribution obligations of each of the
      Guarantors shall be limited to the maximum amount that it can pay at such time
      without rendering its contribution obligations voidable under applicable law
      relating to fraudulent conveyances or fraudulent transfers. As used in this
      subsection, the “Net Worth” of each of the Guarantors means, at any time, the
      remainder of (i) the fair value of such Guarantor’s assets (other than such
      right of contribution), minus (ii) the fair value of such Guarantor’s
      liabilities (other than its liabilities under its guaranty of the Indebtedness).
       

     

    SECTION
      2.9 Subordination.
      Guarantor hereby subordinates and makes inferior to the Indebtedness any and
      all
      Intercompany Debt now or at any time hereafter owed by the Borrower or other
      Obligor to the Guarantor. Guarantor agrees that after the occurrence of any
      Default or Event of Default under the Credit Agreement, it will not permit
      the
      Borrower to repay such Intercompany Debt or any part thereof and it will not
      accept payment from the Borrower of such Intercompany Debt or any part thereof
      without the prior written consent of the Majority Lenders as defined in the
      Credit Agreement. If Guarantor receives any such payment without the prior
      required written consent, the amount so paid shall be held in trust for the
      benefit of the Lenders, shall be segregated from the other funds of such
      Guarantor, and shall forthwith be paid over to the Administrative Agent to
      be
      held by the Administrative Agent as collateral for, or then or at any time
      thereafter applied in whole or in part by the Administrative Agent against,
      all
      or any portions of the Indebtedness, whether matured or unmatured, in such
      order
      as the Administrative Agent shall elect.

    REPRESENTATIONS,
      WARRANTIES AND COVENANTS

     

    SECTION
      3.1 Representations,
      Warranties and Covenants.
      By
      execution hereof, Guarantor covenants and agrees that certain representations,
      warranties, terms, covenants, and conditions set forth in the Credit Agreement
      and other Loan Documents are applicable to Guarantor and shall be imposed upon
      Guarantor, and Guarantor reaffirms that each such representation and warranty
      is
      true and correct and covenants and agrees to promptly and properly perform,
      observe, and comply with each such term, covenant, or condition. Moreover,
      Guarantor acknowledges and agrees that this Guaranty Agreement is subject to
      the
      offset provisions of the Credit Agreement in favor of the Administrative Agent
      and the Lenders.

    MISCELLANEOUS
      PROVISIONS

     

    SECTION
      4.1 Loan
      Document.
      This
      Guaranty Agreement is a Loan Document executed pursuant to the Credit Agreement
      and shall (unless otherwise expressly indicated herein) be construed,
      administered and applied in accordance with the terms and provisions thereof.
       

     

    SECTION
      4.2 Releases.
      At such
      time as the Loans shall have been paid in full, the Commitments have been
      terminated and no Lender Hedging Agreements are outstanding, the Administrative
      Agent shall, at the request and expense of the Guarantor following such
      termination, promptly execute and deliver to the Guarantor such documents and
      instruments as the Guarantor shall reasonably request to evidence termination
      and release of this Guaranty Agreement.  

     

    SECTION
      4.3 Administrative
      Agent and Lenders; Successors and Assigns.  

     

    (a)
      The
      Administrative Agent is Administrative Agent for each Lender under the Credit
      Agreement. All rights granted to Administrative Agent under or in connection
      with this Guaranty Agreement are for each Lender’s ratable benefit. The
      Administrative Agent may, without the joinder of any Lender, exercise any rights
      in Administrative Agent’s or Lenders’ favor under or in connection with this
      Guaranty Agreement. The Administrative Agent’s and each Lender’s rights and
      obligations vis-a-vis
      each
      other may be subject to one or more separate agreements between those parties.
      However, the Guarantor is not required to inquire about any such agreement
