      conversion into a Floating Rate Advance, or three Business Days, in the case

2.4.7  Payment
      Dates; Interest and Fee Basis .
      Subject

      interest accrued on each Floating Rate Advance shall be payable on each Payment

      Interest Period longer than three months shall also be payable on the last

      Rate Advances when such interest is based on the Prime Rate shall be calculated
      for the actual number of days elapsed on the basis of a year consisting of 365
      or, when appropriate, 366 days. All other interest and all fees under Section

      succeeding Business Day and, in the case of a principal payment, such extension
      of time shall be included in computing interest in connection with such

      counterclaim in immediately available funds to the Administrative Agent at

      States specified in writing by the Administrative Agent to the Company (at
      least
      one Business Day prior to the applicable due date). All such payments shall
      be
      made by noon on the date when due and shall be applied (i) first, to any unpaid
      Reimbursement Obligations and interest thereon, ratably among the holders
      thereof in accordance with the amount thereof held by each such holder, (ii)
      second, to any principal and interest due in connection with Advances, ratably
      among the Banks in accordance with their respective Pro Rata Shares, and (iii)
      third, to any other Obligations that are then due, ratably among the Banks
      in
      accordance with their respective Pro Rata Shares. Each payment delivered to
      the
      Administrative Agent for the account of any Bank or the LC Issuer shall be
      delivered by the Administrative Agent to such Bank or the LC Issuer in the
      same
      type of funds which the Administrative Agent received at such Bank’s or the LC
      Issuer’s address specified pursuant to Article
      XIII or at
      any Lending Installation specified in a notice received by the Administrative
      Agent from such Bank. Any payment to be delivered by the Administrative Agent
      pursuant to the foregoing sentence shall be delivered (a) if the corresponding
      payment was received by the Administrative Agent by noon on a Business Day,
      on
      such Business Day, and (b) otherwise, on the Business Day immediately following
      the Administrative Agent’s receipt of the corresponding payment. The Company
      authorizes the Administrative Agent to charge the account of the Company for
      each payment of principal, Reimbursement Obligations and interest as it becomes
      due hereunder. Any payment made by the Company prior to a date when due shall
      be
      applied as the Company may determine; provided that,
      except as otherwise provided herein, any such payment shall be applied ratably
      among the Banks in accordance with their respective Pro Rata Shares. Each
      reference to the Administrative Agent in this Section
      2.4 shall
      also be deemed to refer, and shall apply equally, to the LC Issuer, in the
      case

      any
      Bank to maintain such accounts or any error therein shall not in any manner
      affect the obligation of the Company to repay the Obligations in accordance
      with
      their terms.






16




(iv)  Any
      Bank
      may request that its Loans be evidenced by a Note. In such event, the Company
      shall execute and deliver to such Bank a Note payable to the order of such
      Bank.
      Each Bank is authorized to record on the schedule attached to its Note, or
      otherwise record in accordance with its usual practice, the date and amount
      of
      each Loan made by such Bank; provided that any
      failure to so record shall not affect the Company’s obligations under any Note.




(v)  The
      Company authorizes the Banks and the Administrative Agent to extend Advances
      and
      effect Rate Option selections based on telephonic notices made by any person
      the
      Administrative Agent or any Bank in good faith believes to be an Authorized
      Officer. The Company agrees to deliver promptly to the Administrative Agent
      a
      written confirmation of each telephonic notice signed by an Authorized Officer.
      If the written confirmation differs in any material respect from the action
      taken by the Administrative Agent and the Banks, the records of the
      Administrative Agent and the Banks shall govern absent manifest
      error.




2.4.10  Notification
      of Advances, Interest Rates and Prepayments .
      The
      Administrative Agent will notify each Bank of the contents of each borrowing
      notice and payment notice received by it hereunder promptly and in any event
      before the close of business on the same Business Day of receipt thereof (or,
      in
      the case of borrowing notices with respect to Floating Rate Advances, within
      one
      hour of receipt thereof). Promptly after notice from the LC Issuer, the
      Administrative Agent will notify each Bank of the contents of each request
      for
      issuance of a Facility LC hereunder. The Administrative Agent will notify each
      Bank of the interest rate applicable to each Eurodollar Advance promptly upon
      determination of such interest rate and will give each Bank prompt notice of
      each change in the Prime Rate.




2.4.11  Non-Receipt
      of Funds by the Administrative Agent .
      Unless
      the Company or a Bank, as the case may be, notifies the Administrative Agent
      prior to the date on which it is scheduled to make payment to the Administrative
      Agent of (i) in the case of a Bank, the proceeds of a Loan, or (ii) in the
      case
      of the Company, a payment of principal, interest or fees to the Administrative
      Agent for the account of the Banks, that it does not intend to make such
      payment, the Administrative Agent may assume that such payment has been made.
      The Administrative Agent may, but shall not be obligated to, make the amount
      of
      such payment available to the intended recipient in reliance upon such
      assumption. If such Bank or the Company, as the case may be, has not in fact
      made such payment to the Administrative Agent, the recipient of such payment
      shall, on demand by the Administrative Agent, 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 the date the Administrative Agent recovers
      such amount at a rate per annum equal to (x) in the case of payment by a Bank,
      the Federal Funds Effective Rate for such day or (y) in the case of payment
      by
      the Company, the interest rate applicable to the relevant Loan.




17




2.4.12  Changes
      in Aggregate Commitment . (i) The
      Company may at any time after the date hereof cancel the Aggregate Commitment
      in
      whole, or in a minimum aggregate amount of $5,000,000 (and in integral multiples
      of $1,000,000) ratably among the Banks upon at least five days’ prior written
      notice to the Administrative Agent, which notice shall specify the amount of
      such reduction; provided that no
      such notice of cancellation shall be effective to the extent that it would
      reduce the Aggregate Commitment to an amount which would be less than the
      Aggregate Outstanding Credit Exposure at the time such cancellation is to take
      effect. Any notice of cancellation given pursuant to this Section shall be
      irrevocable and shall specify the date upon which such cancellation is to take
      effect.




(ii)  The
      Company may, from time to time, by means of a letter delivered to the
      Administrative Agent substantially in the form of Exhibit
      E ,
      request
      that the Aggregate Commitment be increased by an amount not exceeding (in the
      aggregate for all such increases) $150,000,000 by (a) increasing the Commitment
      of one or more Banks which have agreed to such increase and/or (b) adding one
      or
      more commercial banks or other Persons as a party hereto (each an “Additional
      Bank”) with a Commitment in an amount agreed to by any such Additional Bank; provided that no
      Additional Bank shall be added as a party hereto without the written consent
      of
      the Administrative Agent (which shall not be unreasonably withheld) or if an
      Unmatured Default or a Default exists. Any increase in the Aggregate Commitment
      pursuant to this clause
      (ii) shall be
      effective three Business Days (or such other period of time as the
      Administrative Agent, the Company and the applicable increasing or new Bank
      shall agree) after the date on which the Administrative Agent has received
      and
      accepted the applicable increase letter in the form of Annex 1 to Exhibit
      E (in the
      case of an increase in the Commitment of an existing Bank) or assumption letter
      in the form of Annex 2 to Exhibit
      E (in the
      case of the addition of a new Bank). The Administrative Agent shall promptly
      notify the Company and the Banks of any increase in the amount of the Aggregate
      Commitment pursuant to this clause
      (ii) and of
      the Commitment and Pro Rata Share of each Bank after giving effect thereto.
      The
      Company acknowledges that, in order to maintain Advances in accordance with
      each
      Bank’s Pro Rata Share of all outstanding Advances prior to any increase in the
      Aggregate Commitment pursuant to this clause
      (ii) ,
      a
      reallocation of the Commitments as a result of a non-pro-rata increase in the
      Aggregate Commitment may require prepayment of all or portions of certain
      Advances on the date of such increase (and any such prepayment shall be subject
      to the provisions of Section
      3.3 ).




2.4.13  Extension
      of Scheduled Termination Date .
      The
      Company may, not more than 90 nor less than 30 days prior to the first and
      second anniversaries of the date of this Agreement (each an “ Anniversary
      Date ”),
      submit to the Administrative Agent a request (an “ Extension
      Request ”)
      for a
      one year extension of the scheduled Termination Date. The Administrative Agent
      shall promptly forward a copy of such Extension Request to each Bank. In
      response to such request, each Bank shall, not later than the earlier of 30
      days
      after receipt of such notice and 15 days prior to the applicable Anniversary
      Date, notify the Administrative Agent whether it is willing (in its sole and
      complete discretion) to extend the scheduled Termination Date for an additional
      year (and any Bank that fails to give such notice to the Administrative Agent
      shall be deemed to have elected not to extend the scheduled Termination Date).
      The Administrative Agent will notify the Company of the decisions of the Banks
      no later than 10 days prior to the relevant Anniversary Date. If the Required
      Banks elect to extend the scheduled Termination Date, then on the relevant
      Anniversary Date the scheduled Termination Date for all Banks that agreed to
      extend the Termination Date shall be extended for an additional year; provided that (a)
      no Default or Unmatured Default exists on such Anniversary Date and (b) the
      representations and warranties set forth in Article
      V are true
      and correct in all material respects on such Anniversary Date. The Commitment
      of
      any Bank that elects, or is deemed to have elected, not to extend the scheduled
      Termination Date (a “ Declining
      Bank ”)
      shall
      terminate on the existing scheduled Termination Date (without regard to any
      extension by the other Banks), and the Pro Rata Shares of the remaining Banks
      shall be appropriately adjusted on such date. The Company may, at its sole
      expense and effort, upon notice to any Declining Bank and the Administrative
      Agent, require such Declining Bank to assign its rights and obligations
      hereunder to an assignee selected by the Company that is willing to accept
      such
      assignment; provided that (i)
      such assignment shall not conflict with any law, rule or regulation or order
      of
      any court or other governmental authority, (ii) in the case of an assignee
      that
      is not a Bank, the Company shall have received a written consent of the
      Administrative Agent and the LC Issuer (which consents shall not be unreasonably
      withheld), and (iii) the Company or such assignee shall have paid (x) to such
      Declining Bank in immediately available funds the principal of and interest
      accrued to the date of such payment on the Loans made by it hereunder and all
      other amounts owed to it hereunder and (y) the fee payable to the Administrative
      Agent pursuant to Section
      12.3.2 .
      Upon
      any such assignment, the scheduled Termination Date for the assignee shall
      be
      the latest scheduled Termination Date for any Bank hereunder.

      Installations .
      Each
      Bank may book its Loans and its participations in any LC Obligations, and the
      LC
      Issuer may book the Facility LCs, at any Lending Installation selected by such
      Bank or the LC Issuer, as the case may be, and each Bank and the LC Issuer
      may
      change its Lending Installation from time to time. Each Bank and the LC Issuer
      will notify the Administrative Agent and the Company on or prior to the date
      of
      this Agreement of the Lending Installation which it intends to utilize for
      each
      type of Loan hereunder or the Facility LCs, as the case may be. Each Bank and
      the LC Issuer may, by written notice to the Administrative Agent and the
      Company, change the Lending Installation through which Loans will be made by
      it
      or Facility LCs will be issued by it and for whose account Loan payments or
      payments with respect to Facility LCs are to be made.




2.6  Withholding
      Tax Exemption .
      At
      least five Business Days prior to the first date on which interest or fees
      are
      payable hereunder for the account of any Bank, each Bank that is not
      incorporated under the laws of the United States of America, or a state thereof,
      agrees that it will deliver to each of the Company and the Administrative Agent
      two duly completed copies of United States Internal Revenue Service Form W-8BEN
      or W-8ECI, certifying in either case that such Bank is entitled to receive
      payments under this Agreement and the Notes without deduction or withholding
      of
      any United States federal income taxes. Each Bank which so delivers a Form
      W-8BEN or W-8ECI further undertakes to deliver to each of the Company and the
      Administrative Agent two additional copies of such form (or a successor form)
      on
      or before the date that such form expires or becomes obsolete or after the
      occurrence of any event requiring a change in the most recent forms so delivered
      by it, and such amendments thereto or extensions or renewals thereof as may
      be
      reasonably requested by the Company or the Administrative Agent, in each case
      certifying that such Bank is entitled to receive payments under this Agreement
      and the Notes without deduction or withholding of any United States federal
      income taxes, unless an event (including any change in treaty, law or
      regulation) has occurred prior to the date on which any such delivery would
      otherwise be required which renders all such forms inapplicable or which would
      prevent such Bank from duly completing and delivering any such form with respect
      to it and such Bank advises the Company and the Administrative Agent that it
      is
      not capable of receiving payments without any deduction or withholding of United
      States federal income tax.

      Company shall pay to the Administrative Agent, for the account of the Banks

      such Facility LC. Such fee shall be calculated for actual days elapsed on the
      basis of a 360-day year and shall be payable in arrears on each Payment Date

      Upon
      receipt from the beneficiary of any Facility LC of any demand for payment under

      Administrative Agent shall promptly notify the Company and each other Bank
      as to
      the amount to be paid by the LC Issuer as a result of such demand and the
      proposed LC Payment Date. The responsibility of the LC Issuer to the Company
      and
      each Bank shall be only to determine that the documents (including each demand
      for payment) delivered under each Facility LC in connection with such
      presentment shall be in conformity in all material respects with such Facility
      LC. The LC Issuer shall endeavor to exercise the same care in the issuance
      and
      administration of the Facility LCs as it does with respect to letters of credit
      in which no participations are granted, it being understood that in the absence
      of any gross negligence or willful misconduct by the LC Issuer, each Bank shall
      be unconditionally and irrevocably liable without regard to the occurrence
      of
      any Default or Unmatured Default or any condition precedent whatsoever, to
      reimburse the LC Issuer on demand for (i) such Bank’s Pro Rata Share of the
      amount of each payment made by the LC Issuer under each Facility LC (the date
      of
      such payment by the LC Issuer, an “ LC
      Payment Date ”)
      to the
      extent such amount is not reimbursed by the Company, or paid by the making
      of a
      Floating Rate Advance, pursuant to Section
      2.7.6 below,
      plus (ii) interest on the foregoing amount to be reimbursed by such Bank, for
      each day from the date of the LC Issuer’s demand for such reimbursement (or, if
      such demand is made after 11:00 a.m. on such date, from the next succeeding
      Business Day) to the date on which such Bank pays the amount to be reimbursed
      by
      it, at a rate of interest per annum equal to the Federal Funds Effective Rate
      for the first three days and, thereafter, at a rate of interest equal to the
      rate applicable to Floating Rate Advances.




21




2.7.6  Reimbursement
      by Company .
      The
      Company shall be irrevocably and unconditionally obligated to reimburse the
      LC
      Issuer on the applicable LC Payment Date for any amount paid by the LC Issuer
      upon any drawing under any Facility LC, without presentment, demand, protest
      or
      other formalities of any kind; provided that
      neither the Company nor any Bank shall hereby be precluded from asserting any
      claim for direct (but not consequential) damages suffered by the Company or
      such
      Bank to the extent, but only to the extent, caused by (i) the willful misconduct
      or gross negligence of the LC Issuer in determining whether a request presented
      under any Facility LC issued by it complied with the terms of such Facility
      LC
      or (ii) the LC Issuer’s failure to pay under any Facility LC issued by it after
      the presentation to it of a request strictly complying with the terms and
      conditions of such Facility LC. If the Company fails to so reimburse the LC
      Issuer by 2:00 P.M. on the applicable LC Payment Date, the Administrative Agent
      shall promptly notify each Bank of such LC Payment Date, the amount of the
      unpaid Reimbursement Obligation and such Bank’s Pro Rata Share thereof. In such
      event, the Company shall be deemed to have requested a Floating Rate Advance
      to
      be disbursed on the applicable LC Payment Date in an amount equal to the unpaid
      Reimbursement Obligation, without regard to the minimum and multiples specified
      in Section
      2.4.2 for
      Floating Rate Advances, but subject to the amount of the unutilized portion
      of
      the Aggregate Commitment and the conditions set forth in Article
      IV .
      Any
      Reimbursement Obligation that is not fully refinanced by the making of a
      Floating Rate Advance because the conditions set forth in Article
      IV cannot
      be satisfied or for any other reason shall bear interest payable on demand
      from
      such LC Payment Date to the date of reimbursement, at a rate of interest per
      annum equal to the rate applicable to Floating Rate Advances (plus, beginning
      on
      the third Business Day after the LC Issuer notifies the Company that the LC
      Issuer has paid the applicable drawing, 2%). The LC Issuer will pay to each
      Bank
      ratably in accordance with its Pro Rata Share all amounts received by it from
      the Company for application in payment, in whole or in part, of the
      Reimbursement Obligation in respect of any Facility LC issued by the LC Issuer,
      but only to the extent such Bank has made payment to the LC Issuer in respect
      of
      such Facility LC pursuant to Section
      2.7.5 .




2.7.7  Obligations
      Absolute .
      The
      Company’s obligations under this Section
      2.7 shall be
      absolute and unconditional under any and all circumstances and irrespective
      of
      any setoff, counterclaim or defense to payment which the Company may have or
      have had against the LC Issuer, any Bank or any beneficiary of a Facility LC.
      The Company further agrees with the LC Issuer and the Banks that the LC Issuer
      and the Banks shall not be responsible for, and the Company’s Reimbursement
      Obligation in respect of any Facility LC shall not be affected by, among other
      things, the validity or genuineness of documents or of any endorsements thereon,
      even if such documents should in fact prove to be in any or all respects
      invalid, fraudulent or forged, or any dispute between or among the Company,
      any
      of its Affiliates, the beneficiary of any Facility LC or any financing
      institution or other party to whom any Facility LC may be transferred or any
      claims or defenses whatsoever of the Company or of any of its Affiliates against
      the beneficiary of any Facility LC or any such transferee. The LC Issuer shall
      not be liable for any error, omission, interruption or delay in transmission,
      dispatch or delivery of any message or advice, however transmitted, in
      connection with any Facility LC. The Company agrees that any action taken or
      omitted by the LC Issuer or any Bank under or in connection with each Facility
      LC and the related drafts and documents, if done without gross negligence or
      willful misconduct, shall be binding upon the Company and shall not put the
      LC
      Issuer or any Bank under any liability to the Company. Nothing in this Section
      2.7.7 is
      intended to limit the right of the Company to make a claim against the LC Issuer
      for damages as contemplated by the proviso to the first sentence of Section
      2.7.6 .




22




2.7.8  Actions
      of LC Issuer .
      The LC
      Issuer shall be entitled to rely, and shall be fully protected in relying,
      upon
      any Facility LC, draft, writing, resolution, notice, consent, certificate,
      affidavit, letter, cablegram, telegram, telecopy, telex or teletype message,
      statement, order or other document believed by it to be genuine and correct
      and
      to have been signed, sent or made by the proper Person or Persons, and upon
      advice and statements of legal counsel, independent accountants and other
      experts selected by the LC Issuer in good faith. The LC Issuer shall be fully
      justified in failing or refusing to take any action under this Agreement unless
      it shall first have received such advice or concurrence of the Required Banks
      as
      it reasonably deems appropriate or it shall first be indemnified to its
      reasonable satisfaction by the Banks against any and all liability and expense
      which may be incurred by it by reason of taking or continuing to take any such
      action. Notwithstanding any other provision of this Section
      2.7 ,
      the LC
      Issuer shall in all cases be fully protected in acting, or in refraining from
      acting, under this Agreement in accordance with a request of the Required Banks,
      and such request and any action taken or failure to act pursuant thereto shall
      be binding upon the Banks and any future holders of a participation in any
      Facility LC.

      and the Administrative Agent, and their respective directors, officers, agents
      and employees from and against any and all claims and damages, losses,
      liabilities, costs or expenses which such Bank, the LC Issuer or the
      Administrative Agent may incur (or which may be claimed against such Bank,
      the
      LC Issuer or the Administrative Agent by any Person whatsoever) by reason of
      or
      in connection with the issuance, execution and delivery or transfer of or
      payment or failure to pay under any Facility LC or any actual or proposed use
      of
      any Facility LC, including any claim, damage, loss, liability, cost or expense
      which the LC Issuer may incur (i) by reason of or in connection with the failure
      of any other Bank to fulfill or comply with its obligations to the LC Issuer
      hereunder (but nothing herein contained shall affect any right the Company
      may
      have against any defaulting Bank) or (ii) by reason of or on account of the
      LC
      Issuer issuing any Facility LC which specifies that the term “Beneficiary”
included therein includes any successor by operation of law of the named
      Beneficiary, but which Facility LC does not require that any drawing by any
      such
      successor Beneficiary be accompanied by a copy of a legal document, satisfactory
      to the LC Issuer, evidencing the appointment of such successor Beneficiary; provided that the
      Company shall not be required to indemnify any Bank, the LC Issuer or the
      Administrative Agent for any claims, damages, losses, liabilities, costs or
      expenses to the extent, but only to the extent, caused by (x) the willful
      misconduct or gross negligence of the LC Issuer in determining whether a request
      presented under any Facility LC complied with the terms of such Facility LC
      or
      (y) the LC Issuer’s failure to pay under any Facility LC after the presentation
      to it of a request strictly complying with the terms and conditions of such
      Facility LC. Nothing in this Section

      intended to limit the obligations of the Company under any other provision
      of

      employees (to the extent not reimbursed by the Company) against any cost,
      expense (including reasonable counsel fees and disbursements), claim, demand,
      action, loss or liability (except such as result from such indemnitees’ gross
      negligence or willful misconduct or the LC Issuer’s failure to pay under any
      Facility LC after the presentation to it of a request strictly complying with
      the terms and conditions of the Facility LC) that such indemnitees may suffer
      or
      incur in connection with this Section
      2.7 or any
      action taken or omitted by such indemnitees hereunder.




2.7.11  Facility
      LC Collateral Account .
      The
      Company agrees that it will, upon the request of the Administrative Agent or
      the
      Required Banks and until the final expiration date of any Facility LC and
      thereafter as long as any amount is payable to the LC Issuer or the Banks in
      respect of any Facility LC, maintain a special collateral account pursuant
      to
      arrangements satisfactory to the Administrative Agent (the “ Facility
      LC Collateral Account ”)
      at the
      Administrative Agent’s office at the address specified pursuant to Article
      XIII ,
      in the
      name of such Company but under the sole dominion and control of the
      Administrative Agent, for the benefit of the Banks and in which the Company
      shall have no interest other than as set forth in Section
      8.1 .
      Except
      as otherwise expressly provided herein, the Company shall have no obligation
      to
      deposit or maintain funds in the Facility LC Collateral Account. The Company
      hereby pledges, assigns and grants to the Administrative Agent, on behalf of
      and
      for the ratable benefit of the Banks and the LC Issuer, a security interest
      in
      all of the Company’s right, title and interest in and to all funds which may
      from time to time be on deposit in the Facility LC Collateral Account to secure
      the prompt and complete payment and performance of the Obligations. The
      Administrative Agent will invest any funds on deposit from time to time in
      the
      Facility LC Collateral Account in certificates of deposit of JPMorgan having
      a
      maturity not exceeding 30 days. Nothing in this Section
      2.7.11 shall
      either obligate the Administrative Agent to require the Company to deposit
      any
      funds in the Facility LC Collateral Account or limit the right of the
      Administrative Agent to release any funds held in the Facility LC Collateral
      Account in each case other than as required by Section
      8.1 ; provided that if
      one or more Facility LCs are outstanding on the Termination Date, the Company
      shall deposit and thereafter maintain funds in the Facility LC Collateral
      Account in an amount equal to the undrawn stated amount available under all
      such
      Facility LCs plus all fees that would be payable thereon pursuant to Section
      2.7.4 assuming
      each Facility LC is drawn on the scheduled expiration date thereof. The
      Administrative Agent shall, at the request of the Company, notify the Company
      of
      (a) the amount of funds on deposit in the Facility LC Collateral Account and
      (b)
      the amount required to be on deposit in the Facility LC Collateral Account
      pursuant to the proviso in the foregoing sentence. So long as no Default or
      Unmatured Default exists, the Administrative Agent shall, promptly upon request
      of the Company, return to the Company any amount held in the Facility LC
      Collateral Account pursuant to the proviso to the second preceding sentence
      in
      excess of the amount required by such proviso.

**ARTICLE
      III**




**CHANGE
      IN CIRCUMSTANCES**




3.1  Yield
      Protection .
      If
      after the date of this Agreement any law or any governmental or
      quasi-governmental rule, regulation, policy, guideline or directive (whether
      or
      not having the force of law), or any interpretation thereof, or compliance
      of
      any Bank or any applicable Lending Installation or the LC Issuer with any of
      the
      foregoing,




(i)  subjects
      any Bank, any applicable Lending Installation or the LC Issuer to any tax,
      duty,
      charge or withholding on or from payments due from the Company (excluding
      taxation of the overall net income of any Bank, any applicable Lending
      Installation or the LC Issuer), or changes the basis of taxation of payments
      to
      any Bank or the LC Issuer in respect of its Loans, Facility LCs or
      participations therein or other amounts due it hereunder, or




(ii)  imposes
      or increases or deems applicable any reserve, assessment, insurance charge,
      special deposit or similar requirement against assets of, deposits with or
      for
      the account of, or credit extended by, any Bank, any applicable Lending
      Installation or the LC Issuer (other than reserves and assessments taken into
      account in determining the interest rate applicable to Eurodollar Advances),
      or




(iii)  imposes
      any other condition the result of which is to increase the cost to any Bank,
      any
      applicable Lending Installation or the LC Issuer of making, funding or
      maintaining Loans or of issuing or participating in Facility LCs or reduces
      any
      amount receivable by any Bank, any applicable Lending Installation or the LC
      Issuer in connection with loans, or requires any Bank, any applicable Lending
      Installation or the LC Issuer to make any payment calculated by reference to
      the
      amount of Loans, Facility LCs or participations therein held or interest
      received by it, by an amount deemed material by such Bank or the LC Issuer,
      or




(iv)  affects
      the amount of capital required or expected to be maintained by any Bank, any
      applicable Lending Installation or the LC Issuer or any corporation controlling
      any Bank or the LC Issuer and such Bank or the LC Issuer, as the case may be,
      determines the amount of capital required is increased by or based upon the
      existence of this Agreement or its obligation to make Loans hereunder or to
      issue or participate in Facility LCs hereunder or of commitments of this
      type,




25




then,
      within 15 days of demand by such Bank or the LC Issuer, the Company shall pay
      such Bank or the LC Issuer, as the case may be, that portion of such increased
      expense incurred (including, in the case of Section
      3.1(iv) ,
      any
      reduction in the rate of return on capital to an amount below that which it
      or
      such Lending Installation or corporation could have achieved but for such law,
      rule, regulation, policy, guideline or directive and after taking into account
      such Bank’s or the LC Issuer’s policies as to capital adequacy) or reduction in
      an amount received which such Bank or the LC Issuer determines is attributable
      to making, funding and maintaining its Loans and/or issuing or participating
      in
      Facility LCs and its Commitment.




3.2  Availability
      of Rate Options .
      If (a)
      any Bank determines, and notifies the Company and the Administrative Agent,
      that
      maintenance of its Eurodollar Loans at a suitable Lending Installation would
      violate any applicable law, rule, regulation or directive, whether or not having
      the force of law, or (b) the Required Banks determine that (i) deposits of
      a
      type and maturity appropriate to match fund Eurodollar Advances are not
      available or (ii) the Eurodollar Rate for any Interest Period does not
      accurately reflect the cost of making or maintaining Eurodollar Loans for such
      Interest Period, then the Administrative Agent shall suspend the availability
      of
      Eurodollar Advances and, in the case of clause
      (a) ,
      require
      any outstanding Eurodollar Loan of such Bank to be repaid at the end of each
      Interest Period therefor or on such earlier date as may be required by the
      applicable law, rule, regulation or directive (it being understood that, so
      long
      as the circumstances described in clause
      (a) continue, such Bank shall make and maintain Floating Rate Loans in an amount
      equal to its Pro Rata Share of each Eurodollar Advance).




3.3  Funding
      Indemnification .
      If any
      payment of a Eurodollar Advance occurs on a date which is not the last day
      of
      the applicable Interest Period, whether because of acceleration, prepayment
      or
      otherwise, or a Eurodollar Advance is not made or continued or a Floating Rate
      Advance is not converted to a Eurodollar Advance on the date specified by the
      Company for any reason other than default by the Banks, the Company will
      indemnify each Bank for any loss or cost incurred by it resulting therefrom,
      including any loss or cost in liquidating or employing deposits acquired to
      fund
      or maintain the Eurodollar Advance (but excluding lost profits).




3.4  Bank
      Statements; Survival of Indemnity .
      To the
      extent reasonably possible, each Bank and the LC Issuer, as applicable, shall
      designate an alternate Lending Installation or take such other actions with
      respect to its Eurodollar Loans or Facility LCs or participations therein to
      reduce any liability of the Company to such Bank or the LC Issuer, as the case
      may be, under Section
      3.1 or to
      avoid the unavailability of a Rate Option under Section
      3.2 ,
      so long
      as such designation or the taking of such actions is not disadvantageous to
      such
      Bank or the LC Issuer, as the case may be. Each Bank and the LC Issuer, as
      the
      case may be, shall deliver a written statement of such Bank as to the amount
      due, if any, under Section
      3.1 or 3.3 .
      Such
      written statement shall set forth in reasonable detail the calculations upon
      which such Bank or the LC Issuer determined such amount and shall be final,
      conclusive and binding on the Company in the absence of manifest error.
      Determination of amounts payable under such Sections in connection with a
      Eurodollar Loan shall be calculated as though each Bank funded its Eurodollar
      Loan through the purchase of a deposit of the type and maturity corresponding
      to
      the deposit used as a reference in determining the Eurodollar Rate applicable
      to
      such Loan, whether in fact that is the case or not. Unless otherwise provided
      herein, the amount specified in the written statement shall be payable within
      10
      Business Days after receipt by the Company of the written statement. The
      obligations of the Company under Sections
      3.1 and 3.3 shall
      survive payment of the Obligations and termination of this
      Agreement.




26




3.5  Substitution
      of Bank .
      In the
      event that any Bank delivers to the Company a certificate as to an amount due
      under Section
      3.1 or
      delivers a notice pursuant to Section
      3.2 ,
      the
      Company may, at its sole expense and effort, require such Bank to transfer
      and
      assign, without recourse (in accordance with Section
      12.3 )
      all
      (but not less than all) of its interests, rights and obligations under this
      Agreement to an assignee which shall assume such assigned obligations (which
      assignee may be another Bank, if a Bank accepts such assignment); provided that (i)
      such assignment shall not conflict with any law, rule or regulation or order
      of
      any court or other governmental authority, (ii) the Company shall have received
      a written consent of the Administrative Agent in the case of an entity that
      is
      not a Bank, which consent shall not be unreasonably withheld, (iii) the Company
      or such assignee shall have paid to the assigning Bank in immediately available
      funds the principal of and interest accrued to the date of such payment on
      the
      Loans made by it hereunder and all other amounts owed to it hereunder and the
      fee payable to the Administrative Agent pursuant to Section
      12.3.2 and (iv)
      nothing in the foregoing is intended or shall be construed as obligating any
      Bank to locate such an assignee.

      license, permit or contract, any related constraints on operating activities,
      including any periodic or permanent shutdown of any facility or reduction in
      the
      level of or change in the nature of operations conducted thereat and any actual
      or potential liabilities to third parties, including employees, and any related
      costs and expenses). On the basis of this review, the Company has reasonably
      concluded that environmental laws (as in effect on the date on which this
      warranty is made or deemed made) are unlikely to have a material adverse effect
      on the business, financial condition, or results of operations of the Company
      and its Subsidiaries, considered as a whole.

      (a) of this Section

      the insurer has admitted in writing its liability for an amount which, when
      deducted from the full amount of the Company’s liability with respect to such
      judgment(s) or order(s), would reduce the Company’s remaining liability to an
      amount less than $30,000,000.

      the release by the Company or any other Person of any toxic or hazardous waste
      or substance into the environment, or any violation of any federal, state or
      local environmental, health or safety law or regulation, which would, in either

**ARTICLE
      VIII**




**ACCELERATION,
      WAIVERS, AMENDMENTS AND REMEDIES**




8.1  Acceleration;
      Facility LC Collateral Account . (i) If any
      Default described in clauses
      (a) through (d) of Section 7.7 occurs
      with respect to the Company, the obligations of the Banks to make Loans
      hereunder and the obligation and power of the LC Issuer to issue Facility LCs
      shall automatically terminate and the Obligations shall immediately become
      due
      and payable without any election or action on the part of the Administrative
      Agent, the LC Issuer or any Bank; and the Company will be and become thereby
      unconditionally obligated, without any further notice, act or demand, to pay
      to
      the Administrative Agent an amount in immediately available funds, which funds
      shall be held in the Facility LC Collateral Account, equal to the excess of
      (x)
      the amount of LC Obligations at such time over (y) the amount on deposit in
      the
      Facility LC Collateral Account at such time which is free and clear of all
      rights and claims of third parties and has not been applied against the
      Obligations (such difference, the “Collateral Shortfall Amount”). If any other
      Default occurs and is continuing, the Required Banks may (a) terminate or
      suspend the obligations of the Banks to make Loans hereunder and the obligation
      and power of the LC Issuer to issue Facility LCs hereunder, or declare the
      Obligations to be due and payable, or both, whereupon the Obligations shall
      become immediately due and payable, without presentment, demand, protest or
      notice of any kind, all of which the Company hereby expressly waives, and (b)
      upon notice to the Company and in addition to the continuing right to demand
      payment of all amounts payable under this Agreement, make demand on the Company
      to pay, and the Company will, forthwith upon such demand and without any further
      notice or act, pay to the Administrative Agent the Collateral Shortfall Amount,
      which funds shall be deposited in the Facility LC Collateral
      Account.




(ii)  If
      at any
      time while any Default exists, the Administrative Agent determines that the
      Collateral Shortfall Amount is greater than zero, the Administrative Agent
      may
      make demand on the Company to pay, and the Company will, forthwith upon such
      demand and without any further notice or act, pay to the Administrative Agent
      the Collateral Shortfall Amount, which funds shall be deposited in the Facility
      LC Collateral Account.




(iii)  The
      Administrative Agent may, at any time or from time to time after funds are
      deposited in the Facility LC Collateral Account, apply such funds to the payment
      of the Obligations and any other amounts as shall from time to time have become
      due and payable by the Company to the Banks or the LC Issuer under the Loan
      Documents.




(iv)  Except
      as
      provided in clause
      (iii) above or
      in the following two sentences, at any time while any Default is continuing,
      neither the Company nor any Person claiming on behalf of or through the Company
      shall have any right to withdraw any of the funds held in the Facility LC
      Collateral Account. Upon the earlier to occur of (x) the indefeasible payment
      in
      full of all Obligations and the termination of the Aggregate Commitment and
      (y)
      the cure or written waiver of all outstanding Defaults, any funds remaining
      in
      the Facility LC Collateral Account (including any investment income and interest
      earned on funds deposited therein) shall be returned by the Administrative
      Agent
      to the Company or paid to whomever may be legally entitled thereto at such
      time.




36




(v)  If,
      within 14 days after acceleration of the maturity of the Obligations or
      termination of the obligations of the Banks to make Loans hereunder and the
      obligation and power of the LC Issuer to issue Facility LCs hereunder as a
      result of any Default (other than any Default as described in clauses
      (a) through (d) of Section
      7.7 with
      respect to the Company) and before any judgment or decree for the payment of
      the
      Obligations due shall have been obtained or entered, the Required Banks (in
      their sole discretion) shall so direct, the Administrative Agent shall, by
      notice to the Company, rescind and annul such acceleration and/or termination.
      The Administrative Agent shall promptly return to the Company any funds
      remaining in the Facility LC Collateral Account (including any investment income
      and interest earned on funds deposited therein) in connection with such
      acceleration and/or termination.




8.2  Amendments .
      Subject
      to the provisions of this Article
      VIII ,
      the
      Required Banks (or the Administrative Agent with the consent in writing of
      the
      Required Banks) and the Company may enter into agreements supplemental hereto
      for the purpose of adding or modifying any provisions to the Loan Documents
      or
      changing in any manner the rights of the Banks or the Company hereunder or
      waiving any Default hereunder; provided that no
      such supplemental agreement shall, without the consent of each Bank affected
      thereby:




(i)  Extend
      the maturity of any Loan or Reimbursement Obligation or reduce the principal
      amount thereof, or reduce the rate or extend the time of payment of interest
      or
      fees thereon.




(ii)  Reduce
      the percentage specified in the definition of Required Banks.




(iii)  Except
      as
      provided in Section
      2.4.13 ,
      extend
      the scheduled Termination Date, increase the amount of the Commitment of any
      Bank hereunder or permit the Company to assign its rights under this
      Agreement.




(iv)  Amend
      this Section
      8.2 or Section
      11.2 .




No
      amendment of any provision of this Agreement relating to the Administrative
      Agent shall be effective without the written consent of the Administrative
      Agent. No amendment of any provision of this Agreement relating to the LC Issuer
      shall be effective without the written consent of the LC Issuer. The
      Administrative Agent may waive payment of any fee required under Section
      2.3.2 or 12.3.2 without
      obtaining the consent of any Bank. The LC Issuer may waive payment of any fee
      or
      charge required under the last sentence of Section
      2.7.4 without
      obtaining the consent of any Bank.




8.3  Preservation
      of Rights .
      No
      delay or omission of the Banks, the LC Issuer or the Administrative Agent to
      exercise any right under the Loan Documents shall impair such right or be
      construed to be a waiver of any Default or an acquiescence therein, and the
      making of a Credit Extension notwithstanding the existence of a Default or
      the
      inability of the Company to satisfy the conditions precedent to such Credit
      Extension shall not constitute any waiver or acquiescence. Any single or partial
      exercise of any such right shall not preclude other or further exercise thereof
      or the exercise of any other right, and no waiver, amendment or other variation
      of the terms, conditions or provisions of the Loan Documents whatsoever shall
      be
      valid unless in writing signed by the Banks required pursuant to Section
      8.2 ,
      and
      then only to the extent in such writing specifically set forth. All remedies
      contained in the Loan Documents or by law afforded shall be cumulative and
      all
      shall be available to the Administrative Agent, the LC Issuer and the Banks
      until the Obligations have been paid in full.

      RATABLE PAYMENTS**

      In
      addition to, and without limitation of, any rights of the Banks under applicable
      law, if the Company becomes insolvent, however evidenced, or any Default occurs
      and is continuing, any indebtedness from any Bank to the Company (including
      all
      account balances, whether provisional or final and whether or not collected
      or
      available but excluding amounts maintained by the Company as part of its normal
      treasury operations used for the purpose of conducting the Company’s ordinary
      ongoing business) may be offset and applied toward the payment of the
      Obligations owing to such Bank, whether or not the Obligations, or any part
      hereof, shall then be due.




11.2  Ratable
      Payments .
      If any
      Bank, whether by setoff or otherwise, has payment made to it upon its
      Outstanding Credit Exposure (other than payments received pursuant to Article

      in a
      greater proportion than that received by any other Bank, such Bank agrees,
      promptly upon demand, to purchase a portion of the Loans held by the other
      Banks
      so that after such purchase each Bank will hold its Pro Rata Share of the
      Aggregate Outstanding Credit Exposure. If any Bank, whether in connection with
      setoff or amounts which might be subject to setoff or otherwise, receives
      collateral or other protection for its Obligations or such amounts which may
      be
      subject to setoff, such Bank agrees, promptly upon demand, to take such action
      necessary such that all Banks share in the benefits of such collateral ratably
      in proportion to their respective Pro Rata Shares. In case any such payment
      is
      disturbed by legal process, or otherwise, appropriate further adjustments shall
      be made.

For
      the
      purposes of this Schedule, the following terms have the following meanings,
      subject to the final two paragraphs of this Schedule:




“Level
      I
      Status” exists at any date if, on such date, the Moody’s Rating is A1 or better *or* the
      S&P Rating is A+ or better.




“Level
      II
      Status” exists at any date if, on such date, (i) the Company has not qualified
      for Level I Status and (ii) the Moody’s Rating is A2 or better *or* the
      S&P Rating is A or better.




“Level
      III Status” exists at any date if, on such date, (i) the Company has not
      qualified for Level I Status or Level II Status and (ii) the Moody’s Rating is
      A3 or better *or* the
      S&P Rating is A- or better.




“Level
      IV
      Status” exists at any date if, on such date, (i) the Company has not qualified
      for Level I Status, Level II Status or Level III Status and (ii) the Moody’s
      Rating is Baa1 or better *or* the
      S&P Rating is BBB+ or better.




“Level
      V
      Status” exists at any date if, on such date, (i) the Company has not qualified
      for Level I Status, Level II Status, Level III Status or Level IV Status and
      (ii) the Moody’s Rating is Baa2 or better *or* the
      S&P Rating is BBB or better.




“Level
      VI
      Status” exists at any date if, on such date, (i) the Company has not qualified
      for Level I Status, Level II Status, Level III Status, Level IV Status or Level
      V Status and (ii) the Moody’s Rating is Baa3 or better *or* the
      S&P Rating is BBB- or better.




“Level
      VII Status” exists at any date if, on such date, the Company has not qualified
      for any other Status.




"Moody's
      Rating" means, at any time, the then-current Rating issued by Moody's Investors
      Service, Inc.





“Rating”
      means, for any credit rating agency, the credit rating assigned to the senior
      unsecured long-term debt securities of the Company without third party credit
      enhancement (or, if no such debt securities are outstanding, the rating that
      such credit rating agency has explicitly stated may be implied from the rating
      it has assigned to the outstanding subordinated unsecured long-term debt
      securities of the Company without third party credit enhancement), and any
      rating assigned to any other debt security of the Company shall be disregarded.
      The Rating in effect at any date is that in effect at the close of business
      on
      such date.











"S&P
      Rating"
      means, at any time, the then-current Rating issued by Standard and Poor's Rating
      Services, a division of The McGraw Hill Companies, Inc.





“Status”
      means Level I Status, Level II Status, Level III Status, Level IV Status, Level
      V Status, Level VI or Level VII Status.




The
      Applicable Margin, the LC Fee Rate, the Facility Fee Rate and the Utilization
      Fee Rate shall be determined in accordance with the foregoing table based on
      the
      Status as determined from the then-current Moody's Rating and S&P Rating. If
      at any time the Company has no Moody's Rating or no S&P Rating, Level VII
      Status shall exist; provided that if
      the reason that there is no Moody’s Rating or no S&P Rating is that Moody’s
      or S&P, as the case may be, ceases to issue debt ratings generally, then the
      Company and the Administrative Agent may select another nationally-recognized
      rating agency to substitute for Moody’s or S&P, as applicable, for purposes
      of this Schedule (and all references herein to Moody’s or S&P, as
      applicable, shall refer to such substitute rating agency), and until such
      substitute rating agency is so selected, the Status shall be determined by
      reference to the rating most recently in effect prior to such
      cessation.





Notwithstanding
      the foregoing, if there is a differential of two or more ratings levels by
      Moody’s and S&P, the Status shall be determined assuming that (a) the higher
      rating is equal to the midpoint of the two ratings (e.g., for a split rating
      of
      A3/A+, A is the midpoint and will be deemed to be the higher rating, and for
      a
      split rating of A1/BBB, A3 is the midpoint and will be deemed to be the higher
      rating) or (b) if there is no exact midpoint, the higher rating is equal to
      the
      higher of the two middle intermediate ratings (e.g., for a split rating of
      Baa1/A+, A is the higher of the two middle intermediate ratings and will be
      deemed to be the higher rating, and for a split rating of A2/BB+, Baa1 is the
      higher of the two middle intermediate ratings and will be deemed to be the
      higher rating).

__________,
      2006




The
      Banks
      which are parties to the


Credit
      Agreement described below




c/o
      JPMorgan Chase Bank, N.A., as Administrative Agent


[Address]




Gentlemen:




I
      am
      counsel for MidAmerican Energy Company, an Iowa corporation (the “Company”), and
      have represented the Company in connection with its execution and delivery
      of an
      Amended and Restated Credit Agreement among the Company, JPMorgan Chase Bank,
      N.A., individually and as Administrative Agent, and the other Banks named
      therein and dated as of July 6, 2006 (the “Agreement”). All capitalized terms
      used in this opinion and not otherwise defined shall have the meanings
      attributed to them in the Agreement.




I
      have
      examined the Company’s articles of incorporation, by-laws and resolutions, the
      Loan Documents and such other matters of fact and law which I deem necessary
      in
      order to render this opinion. Based upon the foregoing, it is my opinion
      that:




l.  The
      Company is a corporation duly incorporated, validly existing and in good
      standing under the laws of its state of incorporation and has all requisite
      authority to conduct its business in each jurisdiction in which its business
      is
      conducted.




2.  The
      execution and delivery of the Loan Documents by the Company and the performance
      by the Company of the Obligations have been duly authorized by all necessary
      corporate action and proceedings on the part of the Company and will
      not:




(a)  require
      any consent of the Company’s shareholders;




(b)  violate
      (i) any law, rule or regulation which is binding upon the Company or the
      Company’s articles of incorporation or by-laws or (ii) to the best of my
      knowledge, any order, writ, judgment, injunction, decree or award, or any
      indenture, instrument or agreement, which is binding upon the Company;
      or




(c)  result
      in, or require, the creation or imposition of any lien pursuant to the
      provisions of any indenture, instrument or agreement which is binding upon
      the
      Company.




3.  The
      Loan
      Documents have been duly executed and delivered by the Company and constitute
      legal, valid and binding obligations of the Company enforceable against the
      Company in accordance with their terms except to the extent the enforcement
      thereof may be limited by bankruptcy, insolvency or similar laws affecting
      the
      enforcement of creditors’ rights generally and subject also to the availability
      of equitable remedies if equitable remedies are sought.









4.  There
      is
      no litigation or proceeding pending or, to my knowledge, threatened against
      the
      Company or any Subsidiary which, if adversely determined, would materially
      adversely affect the business or condition of the Company and its Subsidiaries,
      taken as a whole.




5.  No
      approval, authorization, consent, adjudication or order of any governmental
      authority, which has not been obtained by the Company, is required to be
      obtained by the Company in connection with the execution and delivery of the
      Loan Documents, the borrowings under the Agreement or the payment by the Company
      of the Obligations.




This
      opinion may be relied upon by the Banks and their permitted participants,
      assignees and other transferees.




Very
      truly yours,
