      the provisions contained in the Auction Procedures and in the Settlement
      Procedures are incorporated herein by reference in their entirety and shall
      be

      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

      than
      9:30 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 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.
    2.3  Auction
      Schedule.
    The
      Auction Agent shall conduct Auctions on the Business Day immediately prior

      of Auction Results.
    The
      Auction Agent will advise each Broker-Dealer who submitted a Bid or Sell Order

    (a)  On
      each
      Interest Payment Date, the Auction Agent shall, promptly after its receipt
      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 sum of the aggregate
      number of Tortoise 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 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-
    6
        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 ▇▇▇▇▇▇
      Brothers Inc. 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
      writing.
    (e)  The
      Auction Agent shall maintain a list of Broker-Dealers. 
    2.6  Ownership
      of Tortoise Notes and Submission of Bids by the Company and Its
      Affiliates.
    Neither
      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 not to
      disclose such information or permit disclosure of such information without
      the
      prior 
    7
        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.

      of the Auction Agent.
    (a)  The
      Auction Agent may rely conclusively upon, and shall be fully protected in acting

    (b)  The

      Auction Agent (i) shall not be obligated to invest any money received by it
      hereunder and (ii) shall be under no liability for interest on any money
      received by it hereunder.
    (d)  The
      Auction Agent may perform its duties and exercise its rights hereunder either

      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,

      including, without limitation, acts of God; earthquakes; fires; floods; wars;

      practices in the banking industry to resume performance as soon as practicable
      under the circumstances.
    (f)  The
      Auction Agent shall not be required to, and does not, make any representations
      as to the validity, accuracy, value or genuineness of any signatures or
      endorsements, other than its own and those of its authorized
      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 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.
    10
        (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
      on
      the part of the Auction Agent, shall be full warrant to the Auction Agent for
      any action taken or omitted by it under the provisions of this Agreement upon
      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 be deemed gross negligence.

      Expenses and Indemnification.

      Company shall pay to the Auction Agent from time to time reasonable compensation
      for all services rendered by it under this Agreement and under the Broker-Dealer
      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 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
    11
        connection
      with their exercise or performance of any of their duties hereunder and
      thereunder, except such as may result from its gross negligence or bad
      faith.
    4.4  Auction
      Agent’s Disclaimer.

      Auction Agent makes no representation as to the validity or adequacy of the
      Agreement, the Broker-Dealer Agreements or the Tortoise Notes except to the
      extent otherwise set forth in Section 3.2 and except that the Auction Agent
      hereby represents that the Agreement has been duly authorized, executed and
      delivered by the Auction Agent and constitutes a legal and binding obligation
