      the Auction Procedures for the purpose of determining the Applicable Rate for

    (b)           All
      of the provisions contained in the Auction Procedures and in the Settlement
      Procedures are incorporated herein by reference in their entirety and shall
      be
      deemed to be a part of this Agreement to the same extent as if such provisions
      were set forth fully herein.  In the case of any conflict between the
      terms of any document incorporated herein by reference and the terms hereof,
      the
      terms in this agreement shall control.
    2.2           Preparation
      for Each Auction; Maintenance of Registry of Existing Holders.
    (a)           As
      of the date hereof, the Company shall provide the Auction Agent with a list
      of
      the Broker-Dealers and shall deliver to the Auction Agent for execution by
      the
      Auction Agent a Broker-Dealer Agreement signed by each such
      Broker-Dealer.  Not later than five Business Days prior to any Auction
      Date for which any change in such list of Broker-Dealers is to be effective,
      the
      Company shall notify the Auction Agent in writing of such change and, if any
      such change is the addition of a Broker-Dealer to such list, the Company shall
      cause to be delivered to the Auction Agent for execution by the Auction Agent
      a
      Broker-Dealer Agreement signed by such Broker-Dealer.  The Auction
      Agent shall have entered into a Broker-Dealer Agreement with each Broker-Dealer
      prior to the participation of any such Broker-Dealer in any
      Auction.
    (b)           In
      the event that the Auction Date for any Auction shall be changed, the Auction
      Agent, by such means as the Auction Agent reasonably deems practicable, shall
      give notice of such change to the Broker-Dealers not later than the earlier
      of
      9:15 a.m. on the new Auction Date or 9:15 a.m. on the old Auction
      Date.
    (c)           The
      provisions contained in Section 2.04 of the Supplemental Indenture concerning
      Special Rate Periods and the notification of a Special Rate Period will be
      followed by the Company and, to the extent applicable, the Auction Agent, and
      the provisions contained therein are incorporated herein by reference in their
      entirety and shall be deemed to be a part of this Agreement to the same extent
      as if such provisions were set forth fully herein.
    (d)           (i)           On
      each Auction Date, the Auction Agent shall determine the Maximum
      Rate.  Not later than 10:30 a.m. on each Auction Date, the Auction
      Agent shall notify the Company and the Broker-Dealers of the Reference Rate
      and
      the Maximum Rate in effect on such Auction Date.
    3
        (ii)           If
      the Reference Rate is the applicable “AA” Composite Commercial Paper Rate and
      such rate is to be based on rates supplied by Commercial Paper Dealers and
      one
      or more of the Commercial Paper Dealers shall not provide a quotation for the
      determination of the applicable “AA” Composite Commercial Paper Rate, the rate
      shall be determined on the basis of the quotations (or quotation) furnished
      by
      the remaining Commercial Paper Dealer(s), if any, or, if there are no such
      Commercial Paper Dealers, by a nationally recognized dealer in commercial paper
      of such issuers then making such quotations selected by the
      Company.
    (e)           (i)           The
      Auction Agent shall maintain a registry of the Existing Holders of the Tortoise
      Notes (the “Tortoise Note Register”) for purposes of Auctions and shall indicate
      thereon the identity of the Broker-Dealer that submitted the most recent Order
      in any Auction, which resulted in such Existing Holder continuing to hold or
      purchase such Tortoise Notes.  The Auction Agent may consider a
      Broker-Dealer which has submitted an Order as the Existing Holder for the
      purposes of the Tortoise Note Register; provided, that the Auction Agent may
      request the Broker-Dealer to provide a list of its customers if in its sole
      discretion it determines to do so.  The Auction Agent may conclusively
      rely upon the information furnished to the Auction Agent by the Broker-Dealer
      and notices from the Securities Depository regarding the results of redemptions
      or mandatory tenders.
    (ii)           In
      the event of any partial redemption of Tortoise Notes, upon notice by the
      Company to the Trustee of such partial redemption (delivered at least one day
      prior to the date a notice of redemption is required to be given to the Holders
      of Tortoise Notes to be redeemed), the Trustee promptly shall request the
      Securities Depository to notify it of the identities of the Agent Members (and
      the respective numbers of Tortoise Notes) from the accounts of which Tortoise
      Notes have been called for redemption and the person or department at such
      Agent
      Member to contact regarding such redemption.  At least two Business
      Days prior to the date of redemption, the Trustee shall request each Agent
      Member so identified to disclose to it (upon selection by such Agent Member
      of
      the Existing Holders whose Tortoise Notes are to be redeemed) the number of
      Tortoise Notes of each such Existing Holder, if any, to be redeemed by the
      Company, provided that the Trustee has been furnished with the name and
      telephone number of a person or department at such Agent Member from which
      it is
      to request such information.  Promptly upon its receipt of such
      information, the Trustee shall provide such information to the Auction Agent
      in
      writing.  In the absence of receiving any such information with
      respect to an Existing Holder, from such Existing Holder’s Agent Member or
      otherwise, the Auction Agent may continue to treat such Existing Holder as
      having ownership of the number of Tortoise Notes shown in the Auction Agent’s
      registry of Existing Holders.
    (iii)           The
      Auction Agent shall register a transfer of the ownership of Tortoise Notes
      from
      an Existing Holder to another Existing Holder, or to another Person if permitted
      by the Company, only if (A) such transfer is made pursuant to an Auction or
      (B)
      if such transfer is made other than pursuant to an Auction, the Auction Agent
      has been notified of such transfer in writing, in a notice substantially in
      the
      form of Exhibit C to the Broker-Dealer Agreement, by such Existing Holder or
      by
      the Agent Member of such Existing Holder only to or through a Broker-Dealer
      that
      has entered into a Broker-Dealer Agreement with the Auction Agent and the
      Company or other persons as the Company permits.  The Auction Agent is
      not required to accept any notice of transfer delivered for an Auction unless
      it
      is received by the Auction Agent by 3:00 p.m. on the Business Day preceding
      the
      Auction.  The Auction Agent shall rescind a transfer
    4
        made
      on
      the registry of the Existing Holders of any Tortoise Notes if the Auction Agent
      has been notified in writing, in a notice substantially in the form of Exhibit
      D
      to the Broker-Dealer Agreement, by the Agent Member or the Broker-Dealer of
      any
      Person that (i) purchased any Tortoise Notes and the seller failed to deliver
      such Tortoise Notes or (ii) sold any Tortoise Notes and the purchaser failed
      to
      make payment to such Person upon delivery to the purchaser of such Tortoise
      Notes.
    (f)           The
      Auction Agent may, but shall have no obligation to, request that the
      Broker-Dealers, as set forth in Section 3.2(c) of the Broker-Dealer Agreements,
      provide the Auction Agent with a list of their respective customers that such
      Broker-Dealers believe are Beneficial Owners of Tortoise Notes.  The
      Auction Agent shall keep confidential any such information and shall not
      disclose any such information so provided to any Person other than the relevant
      Broker-Dealer and the Company, provided that the Auction Agent reserves the
      right to disclose any such information if (a) it is ordered to do so by a court
      of competent jurisdiction or a regulatory body, judicial or quasi-judicial
      agency or authority having the authority to compel such disclosure, (b) it
      is
      advised by its counsel in writing that its failure to do so would be unlawful,
      or (c) it is advised by its counsel in writing that failure to do so could
      expose the Auction Agent to loss liability, claim or damage for which it has
      not
      received indemnity or security satisfactory to it.

      of funds from the Company, pay to each Broker-Dealer a service charge in the
      amount equal to:  (i) in the case of any Auction immediately preceding
      a Rate Period of less than one year, the product of (A) a fraction the numerator
      of which is the number of days in the Rate Period (calculated by counting the
      first day of such Rate Period but excluding the last day thereof) and the
      denominator of which is 360, times (B) ¼ of 1%, times (C) $25,000 times (D) the

      Notes placed by such Broker-Dealer, or (ii) the amount mutually agreed upon
      by
      the Company and the Broker-Dealers in the case of any Auction immediately
      preceding a Rate Period of one year or longer.  For the purposes of
      the preceding sentence, the Tortoise Notes shall be placed by a Broker-Dealer
      if
      such notes were (1) the subject of Hold Orders deemed to have been submitted
      to
      the Auction Agent by the Broker-Dealer and were acquired by the Broker-Dealer
      for its own account or were acquired by the Broker-Dealer for its customers
      who
      are Beneficial Owners or (2) the subject of an Order submitted by the
      Broker-Dealer that is (a) a Submitted Bid of an Existing Holder that resulted
      in
      the Existing Holder continuing to hold the notes as a result of the Auction
      or
      (b) a Submitted Bid of a Potential Holder that resulted in the Potential
      Holder
    6
        purchasing
      the notes as a result of the Auction or (3) the subject of a valid Hold
      Order.  For the avoidance of doubt, only one Broker-Dealer shall be
      considered to have placed a particular Tortoise Note at any particular Auction
      for purposes of this Section 2.5(a).
    (b)           The
      Company shall not designate any Person to act as a Broker-Dealer, or permit
      an
      Existing Holder or a Potential Beneficial Owner to participate in Auctions
      through any Person other than a Broker-Dealer, without the prior approval of
      the
      Auction Agent, which approval shall not be withheld
      unreasonably.  Notwithstanding the foregoing, the Company may
      designate an Affiliate of ____________________ to act as a
      Broker-Dealer.
    (c)           The
      Auction Agent shall terminate any Broker-Dealer Agreement as set forth therein
      if so directed by the Company.
    (d)           Subject
      to Section 2.5(b) hereof, the Auction Agent from time to time shall enter into
      such Broker-Dealer Agreements as the Company shall request in

    2.6           Ownership
      of Tortoise Notes and Submission of Bids by the Company and Its Affiliates.

      the Company nor any Affiliate of the Company may submit an Order in any Auction,
      except that an Affiliate of the Company that is a Broker-Dealer may submit
      an
      Order.  The Company shall notify the Auction Agent if the Company or,
      to the best of the Company’s knowledge, any Affiliate of the Company becomes a
      Beneficial Owner of any Tortoise Notes.  The restrictions in this
      Section 2.6 shall in no way limit the activities of the Auction
      Agent.  The Auction Agent shall have no duty or liability with respect
      to enforcement of this Section 2.6.
    2.7           Access
      to and Maintenance of Auction Records.
    The
      Auction Agent shall afford to the Company, its agents, independent public
      accountants and counsel, at reasonable times during normal business hours,
      access to all books, records, documents and other information concerning the
      conduct and results of Auctions, to review and make extracts or copies of (at
      the Company’s sole cost and expense), provided that any such agent, accountant
      or counsel shall furnish the Auction Agent with a letter from the Company
      requesting that the Auction Agent afford such person access.  The
      Auction Agent shall maintain records relating to any Auction for a period of
      at
      least six years after such Auction, and such records, in reasonable detail,
      shall reflect accurately and fairly the actions taken by the Auction Agent
      hereunder.  The Company agrees to keep confidential any information
      regarding the customers of any Broker-Dealer received from the Auction Agent
      in
      connection with this Agreement or any Auction, and shall not disclose such
      information or permit the disclosure of such information without the prior
      written consent of the applicable Broker-Dealer to anyone except such agent,
      accountant or counsel engaged to audit or review the results of Auctions as
      permitted by this Section 2.7.  The Company reserves the right to
      disclose any such information if it is ordered to do so by a court of competent
      jurisdiction or a regulatory body, judicial or quasi-judicial agency or
      authority having authority to compel such disclosure, or if it is advised by
      its
      counsel that its failure to do so would be unlawful.  Any such agent,
      accountant or counsel, before having access to such information, shall agree
      to
      keep such information confidential and
    7
        not
      to
      disclose such information or permit disclosure of such information without
      the
      prior written consent of the applicable Broker-Dealer, provided that such agent,
      accountant or counsel may reserve the right to disclose any such information
      if
      it is ordered to do so by a court of competent jurisdiction or a regulatory
      body, judicial or quasi-judicial agency or authority having authority to compel
      such disclosure, or if it is advised by its counsel that its failure to do
      so
      would be unlawful.
    2.8           Information
      Concerning Rates.
    If
      there is any change in the credit
      rating of Tortoise Notes by a Rating Agency (or substitute or successor Rating
      Agencies) then rating the Tortoise Notes that results in any change in the
      applicable percentage of the “AA” Composite Commercial Paper Rate used to
      determine the Maximum Rate for Tortoise Notes (the “Rate Multiple”), the Company
      shall notify the Auction Agent of such change in the Rate Multiple by no later
      than the Business Day immediately preceding the next Auction Date.  In
      determining the Maximum Rate on any Auction Date, the Auction Agent shall be
      entitled to rely on the last Rate Multiple for Tortoise Notes of which it has
      most recently received notice from the Company.

      with the Company or with the Broker-Dealers or with both.
    (b)           The
      Auction Agent may consult with counsel of its choice and the advice of such

      any misconduct or negligence on the part of any agent or attorney appointed
      by
      it with due care hereunder.
    (e)           The
      Auction Agent shall not be responsible or liable for any failure or delay in
      the
      performance of its obligations under this Agreement arising out of or caused,

      Auction Agent shall use reasonable efforts which are consistent with accepted
      practices in the banking industry to resume performance as soon as practicable
      under the circumstances.

      Auction Agent shall not be required to, and does not, make any representations

      officers.
    (g)           Any
      corporation into which the Auction Agent may be merged or converted or with
      which it may be consolidated, or any corporation resulting from any merger,
      conversion or consolidation to which the Auction Agent shall be a party, or
      any
      corporation succeeding to the dealing and trading business of the Auction Agent
      shall be the successor of the Auction Agent hereunder, with the consent of
      the
      Company but without the execution or filing of
    10
        any
      paper
      with any party hereto or any further act on the part of any of the parties
      hereto, except where any instrument of transfer or assignment may be required
      by
      law to effect such succession, anything herein to the contrary
      notwithstanding.
    (h)           All
      the rights, privileges, immunities and protections granted to the Auction Agent

      capacities it undertakes in connection with this Agreement.
    (i)           Whenever
      in the administration of the provisions of this Agreement, the Auction Agent
      shall deem it necessary or desirable that a matter be proved or established
      prior to taking or suffering any action to be taken hereunder, such matter
      (unless other evidence in respect thereof be herein specifically prescribed)
      may, in the absence of gross negligence or bad faith on the part of the Auction
      Agent, be deemed to be conclusively proved and established by a certificate
      describing such action as requested by the Company or the Broker-Dealer, signed
      by the Company or the Broker-Dealer, respectively, and delivered to the Auction
      Agent and such certificate, in the absence of gross negligence or bad faith

      the faith thereof.  Upon receipt of any such certificate signed by the
      Company or the Broker-Dealer, the Auction Agent shall promptly provide a copy
      of
      said certificate to the Broker-Dealer or the Company,
      respectively.  The Auction Agent shall not be bound to make any
      investigation into the facts or matters stated in any resolution, certificate,
      statement, instrument, opinion, report, notice, request, consent, entitlement,
      order, approval or other paper or document furnished by the Company or the
      Broker-Dealer, except to the extent that such failure to investigate would

      deemed gross negligence.

      Expenses and Indemnification.

      Company shall pay to the Auction Agent from time to time reasonable compensation

      Agreements as shall be set forth in a separate writing signed by the Company
      and
      the Auction Agent, subject to adjustments if the Tortoise Notes no longer are
      held of record by the Securities Depository or its nominee or if there shall
      be
      such other change as shall increase or decrease materially the Auction Agent’s
      obligations hereunder or under the Broker-Dealer Agreements.
    (b)           The
      Company shall reimburse the Auction Agent upon its request for all reasonable
      expenses, disbursements and advances incurred or made by the Auction Agent
      in
      accordance with any provision of this Agreement and of the Broker-Dealer
      Agreements (including the reasonable compensation, expenses and disbursements
      of
      its agents and counsel), except any expense, disbursement or advance
      attributable to the Auction Agent’s gross negligence or bad faith, upon
      submission to the Company of reasonable documentation thereof.  In no
      event shall the Auction Agent be responsible or liable for special, indirect
      or
      consequential loss or damage of any kind whatsoever (including, but not limited
      to, loss of profit), even if the Auction Agent has been advised of the
      likelihood of such loss or damage and regardless of the form of
      action.
    (c)           The
      Company shall indemnify the Auction Agent and its officers, directors, employees
      and agents for, and hold them harmless against, any loss, liability
      or
    11
        expense
      incurred without negligence or bad faith on the part of the Auction Agent
      arising out of or in connection with its agency under this Agreement and under
      the Broker-Dealer Agreements, including the costs and expenses of defending
      themselves against any claim of liability in connection with their exercise
      or

      may
      result from its gross negligence or bad faith.
