the Effective Date, contained an untrue statement of a material fact or omitted
to state any material fact required to be stated therein or necessary to make

contained therein, as to which such counsel expresses no opinion), as of its
date and as of the Delivery Date, contained or contains an untrue statement of a
material fact or omitted or omits to state a material fact required to be stated

          Investment Advisers Act Rules and Regulations or the 1940 Act Rules
          and Regulations from acting under the Advisory Agreement as
          contemplated by the Registration Statement, the Preliminary Prospectus
          and the Prospectus;

                    (iii) This Agreement and the Advisory Agreement have each
          been duly authorized, executed and delivered by the Investment
          Adviser, and constitute the valid and legally binding agreements of
          the Investment Adviser, and, this Agreement is enforceable against the
          Investment Adviser in accordance with its terms;

                    (iv) None of the execution, delivery and performance of this
          Agreement by the Investment Adviser, the performance of the Advisory
          Agreement or the consummation of the transactions contemplated by this
          Agreement or the Advisory Agreement by the Company (i) conflict with,
          result in the creation or imposition of any lien, charge or
          encumbrance upon the assets of the Investment Adviser under the terms
          or provisions of, or result in a breach or violation of any of the
          terms or provisions of, or constitute a default under, any agreement
          listed on Exhibit A attached to such opinion (ii) result in any
          violation of the provisions of the limited liability company operating
          agreement or other organizational documents of the Investment Adviser
          or (iii) result in any violation of any statute or any order, rule or
          regulation known to such counsel of any court or governmental agency
          or body having jurisdiction over the Investment Adviser or any of its
          properties or assets, except in the case of clauses (i) and (iii),
          such conflicts, breaches and violations that in the aggregate would
          not reasonably be expected to have a Material Adverse Effect; and
          except for the registration of the

          Tortoise Notes under the Securities Act and the 1940 Act, and such
          consents, approvals, authorizations, registrations or qualifications
          as may be required under the Exchange Act and applicable state
          securities laws (as to which such counsel need not express an
          opinion), no consent, approval, authorization or order of, or filing
          or registration with, any such court or governmental agency or body is
          required for the execution, delivery and performance of this
          Agreement, the performance of the Advisory Agreement or the
          consummation of the transactions contemplated by this Agreement or the
          Advisory Agreement by the Investment Adviser;

                    (v) To such counsel's knowledge and other than as set forth
          in the Preliminary Prospectus and the Prospectus, there are no legal
          or governmental proceedings pending to which the Investment Adviser is
          a party or to which any property or assets of the Investment Adviser
          is the subject which is reasonably likely to be determined adversely
          to the Investment Adviser and, if determined adversely to the
          Investment Adviser, would be reasonably likely to have a Material
          Adverse Effect; and, to such counsel's knowledge, no such proceedings
          are threatened or contemplated by governmental authorities or
          threatened by others; and

                    (vi) The description of the Investment Adviser and its
          business in the Registration Statement, the Preliminary Prospectus and
          the Prospectus complied and comply in all material respects with the
          requirements of the Securities Act, the 1940 Act, the Investment
          Advisers Act, the Rules and Regulations and the Investment Advisers
          Act Rules and Regulations.

          In rendering such opinion, such counsel may state that their opinion
is limited to matters governed by the Federal laws of the United States of
America, the General Corporation Law of the State of Delaware, and the laws of
the State of Missouri.

               (e) The Underwriters shall have received from ________________,

Board of Directors, its Chief Executive Officer or President and its Chief
Financial Officer or Treasurer or an Assistant Treasurer stating that:

                    (i) The representations, warranties and agreements of the
     Company contained herein and in the Auction Agreement are true and correct
     as of the date hereof and as of the Delivery Date; the Company has complied
     with all its agreements contained herein prior to or on the Delivery Date;
     and the conditions set forth in Section 9 have been fulfilled;

                    (ii) Since the respective dates as of which information is
     given in the Preliminary Prospectus and the Prospectus, other than as set

     reasonably be expected to have a Material Adverse Effect, (B) there has not
     been any change in the capital stock, short-term debt or long-term debt of
     the Company that might reasonably be expected to have a Material Adverse
     Effect, (C) the Company has not incurred any material liability or
     obligation, direct or contingent, (D) there has not occurred a material
     loss or interference with the Company's business from fire, explosion,

     Company has not declared or paid any dividend on its shares of common
     stock, except for dividends declared in the ordinary course of business,
     and, except as set forth in or contemplated by the Preliminary Prospectus
     and the Prospectus, the Company has not entered into any transaction (other
     than purchases and sales of portfolio transactions) or agreement (other
     than investment-related agreements) material to the Company; and

                    (iii) They carefully have examined the Registration
     Statement, the 1940 Act Notification, the Disclosure Package and the
     Prospectus, and any amendments or supplements thereto (including any
     documents incorporated or deemed to be incorporated by reference into the
     Preliminary Prospectus and the Prospectus), and, in their opinion (and in
     forming such opinion each officer may rely on information provided by the
     other parties to this Agreement) (A) the Registration Statement, as of the
     Effective Date, the 1940 Act Notification, as of its date, the Disclosure
     Package, as of the Applicable Time, and the Prospectus, as of its date, did
     not and, on the Delivery Date, will not contain any untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading, and (B)
     since the initial Effective Date of the Registration Statement, no event
     has occurred which should have been set forth in a supplement to, or
     amendment of, the Registration Statement, the Preliminary Prospectus or the
     Prospectus which has not been so set forth.

               (i) The Investment Adviser shall have furnished to the
Underwriters on the Delivery Date a certificate, dated the Delivery Date, of a
member of its Board of Managers, dated the Delivery Date, stating that:

                    (i) The representations, warranties and agreements of the
     Investment Adviser contained herein are true and correct as of the date
     hereof and as of the Delivery Date; the Investment Adviser has complied
     with all its agreements contained herein prior to or on the Delivery Date;
     and the conditions set forth in Section 9 of this Agreement have been
     fulfilled; and

                    (ii) They have examined the Registration Statement, the
     Disclosure Package and the Prospectus, and any amendments or supplements
     thereto (including any documents incorporated or deemed to be incorporated
     by reference into the Preliminary Prospectus and the Prospectus), and, in
     their opinion (and in forming such opinion each officer may rely on
     information provided by the other parties to this Agreement) (A) the
     Registration Statement, as of the Effective Date, the Disclosure Package,
     as of the Applicable Time, and the Prospectus, as of its date, did not and,
     on the Delivery Date, will not contain any untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading, and (B) since the
     initial Effective Date of the Registration Statement, no event has occurred
     which should have been set forth in a supplement to, or amendment of, the
     Registration Statement, the Preliminary Prospectus or the Prospectus which
     has not been so set forth and there has been no document required to be
     filed under the Securities Act, the 1940 Act, the Trust Indenture Act or by
     the Rules and Regulations or the Exchange Act and the rules and regulations
     thereunder that upon such filing would be deemed incorporated by reference
     into the Registration Statement, the Preliminary Prospectus or the
     Prospectus that has not be so filed.

               (j) The Company shall not have sustained since the date of the
latest audited financial statements included in the Preliminary Prospectus and
the Prospectus

(A) any loss or interference with its business from fire, explosion, flood or
other calamity, whether or not covered by insurance, or from any labor dispute
or court or governmental action, order or decree, or (B) since such date, there
shall not have been any change in the capital stock, short-term debt or
long-term debt of the Company or any change, or any development involving a
prospective change, in or affecting the general affairs, management, financial
position, prospects, shareholders' equity or results of operations of the
Company, otherwise than as described or contemplated in the Preliminary
Prospectus or the Prospectus, the effect of which, in any such case described in
clause (A) or (B), is, in the judgment of the Representative, so material and
adverse as to make it impracticable or inadvisable to proceed with the public
offering or the delivery of the Tortoise Notes being delivered on the Delivery
Date on the terms and in the manner contemplated in the Preliminary Prospectus,
the Prospectus and in this Agreement.

               (k) The Company shall have furnished to the Underwriters a report
showing compliance with the asset coverage requirements of the 1940 Act and the
1940 Act Tortoise Notes Asset Coverage (as defined in the Registration
Statement), each dated as of the Delivery Date and in form and substance
satisfactory to the Underwriters. Each such report shall assume the receipt of
the net proceeds from the sale of the Tortoise Notes and may use portfolio
holdings and valuations as of the close of business of any day not more than six
business days preceding the Delivery Date, provided, however, that the Company
represents in such report that its total net assets as of the Delivery Date have
not declined by 5% or more from such valuation date.

               (l) The Company shall have delivered and the Underwriters shall
have received evidence satisfactory to it that the Tortoise Notes are rated at
least "Aaa" by Moody's Investors Service, Inc. and "AAA" by Fitch, Inc., a
division of the McGraw Hill Companies, as of the Delivery Date, and subsequent
to the execution and delivery of this Agreement, (i) no downgrading shall have
occurred in the rating accorded the Tortoise Notes by any "nationally recognized
statistical rating organization" as that term is defined by the Commission for
purposes of Rule 436(g)(2) of the 1933 Act Rules and Regulations and (ii) no
such organization shall have publicly announced that is has under surveillance
or review, with possible negative implications, its rating of the Tortoise
Notes.

               (m) Neither the Company nor the Investment Adviser shall have
failed at or prior to the Delivery Date to have performed or complied with any
of the agreements contained herein and required to be performed or complied with
by them at or prior to the Delivery Date.

               (n) Subsequent to the execution and delivery of this Agreement
there shall not have occurred any of the following: (i) trading in securities
generally on the New York Stock Exchange or the American Stock Exchange or in
the over-the-counter market, or trading in any securities of the Company on any
exchange or in the over-the-counter market, shall have been suspended or
materially limited or the settlement of such trading generally shall have been
materially disrupted or minimum prices shall have been established on any such
exchange or such market by the Commission, by such exchange

or by any other regulatory body or governmental authority having jurisdiction,
(ii) a banking moratorium shall have been declared by Federal or state
authorities, (iii) the United States shall have become engaged in hostilities,
there shall have been an escalation in hostilities involving the United States
or there shall have been a declaration of a national emergency or war by the
United States or (iv) there shall have occurred such a material adverse change
in general economic, political or financial conditions (or the effect of
international conditions on the financial markets in the United States shall be
such), including, without limitation, as a result of terrorist activities after
the date hereof, or any other calamity or crisis as to make it, in the judgment
of the Representative, impracticable or inadvisable to proceed with the public
offering or delivery of the Tortoise Notes being delivered on such Delivery Date
on the terms and in the manner contemplated in the Prospectus.

               (o) The Underwriters shall not have discovered and disclosed to
the Company on or prior to the Delivery Date that the Registration Statement,
any Prospectus Supplement or the Prospectus or any amendment or supplement
thereto contains an untrue statement of a fact which, in the reasonable opinion
of ________________, counsel for the Underwriters, is material or omits to state
a fact which, in the reasonable opinion of such counsel, is material and is
required to be stated therein or is necessary to make the statements therein not
misleading.

               (p) The Company and the Investment Adviser shall have furnished
to the Underwriters such further certificates, documents and opinions of counsel
as the Underwriters shall reasonably request (including certificates of officers
of the Company and the Investment Adviser).

     All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriters.

     Section 10. Indemnification and Contribution.

               (a) The Company and the Investment Adviser shall jointly and
severally indemnify and hold harmless each Underwriter, its directors, officers
and employees and each person, if any, who controls any Underwriter within the
meaning of the Securities Act, from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof (including, but
not limited to, any loss, claim, damage, liability or action relating to
purchases and sales of Tortoise Notes), to which such Underwriter, director,
officer, employee or controlling person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in the 1940 Act Notification, or (B)
in the Registration Statement, the Preliminary Prospectus, the Prospectus, the
Disclosure Package, any amendment or supplement thereto including information
deemed to be part of the Registration Statement pursuant to Rule 430B, or any
"issuer information" filed or required to be filed pursuant to the 1933 Act
Rules and Regulations (ii) the omission or alleged omission to state in the
Registration Statement as amended or supplemented, the

Preliminary Prospectus, the Prospectus, the Disclosure Package, or any such
issuer information, a material fact required to be stated therein or necessary
to make the statements therein not misleading or (iii) any act or failure to act
or any alleged act or failure to act by such Underwriter in connection with, or
relating in any manner to, the Tortoise Notes or the offering contemplated
hereby, and which is included as part of or referred to in any loss, claim,
damage, liability or action arising out of or based upon matters covered by
clause (i) or (ii) above (provided that neither the Company nor the Investment
Adviser shall be liable under Section 10(a) to the extent that it is determined
in a final judgment by a court of competent jurisdiction that such loss, claim,
damage, liability or action resulted directly from any such acts or failures to
act undertaken or omitted to be taken by such Underwriter through its willful
misfeasance, bad faith or gross negligence in the performance of its duties or
reckless disregard of applicable obligations and duties), and shall reimburse
such Underwriter and each such director, officer, employee or controlling person
promptly upon demand for any legal or other expenses reasonably incurred by such
Underwriter, director, officer, employee or controlling person in connection
with investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
however, that neither the Company nor the Investment Adviser shall be liable in
any such case to the extent that any such loss, claim, damage, liability or
action arises out of, or is based upon, any untrue statement or alleged untrue
statement or omission or alleged omission made in reliance upon and in
conformity with written information furnished to the Company or the Investment
Adviser by or on behalf of the Underwriters through the Representative
specifically for inclusion therein which information consists solely of the
information specified in Section 14. The foregoing indemnity agreement is in
addition to any liability which the Company or the Investment Adviser may
otherwise have to any Underwriter or to any director, officer, employee or
controlling person of that Underwriter.

               (b) Each Underwriter, severally and not jointly, shall indemnify
and hold harmless the Company, its officers and employees, each of its
directors, and each person, if any, who controls the Company within the meaning
of the Securities Act, from and against any loss, claim, damage or liability,
joint or several, or any action in respect thereof, to which the Company or any
such director, officer, employee or controlling person may become subject, under
the Securities Act or otherwise, insofar as such loss, claim, damage, liability
or action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement, the
Preliminary Prospectus, the Prospectus, the Disclosure Package, the Registration
Statement as amended or supplemented, or (ii) the omission or alleged omission
to state in the Registration Statement, the Preliminary Prospectus, the
Prospectus, the Disclosure Package, or the Registration Statement as amended or
supplemented, any material fact required to be stated therein or necessary to
make the statements therein not misleading, but in each case only to the extent
that the untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Underwriters specifically for
inclusion therein, which information is limited to the information set forth in
Section 14, and shall reimburse the Company and any such director, officer,
employee or controlling person for any legal or other expenses reasonably
incurred by the Company or

any such director, officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred. The foregoing
indemnity agreement is in addition to any liability which the Underwriters may
otherwise have to the Company or any such director, officer, employee or
controlling person.

               (c) Promptly after receipt by an indemnified party under this
Section 10 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 10, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 10 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 10.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party. After notice from
the indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 10 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the indemnified party shall have the right to employ separate counsel to
represent the indemnified party, and its respective directors, officers,
employees and controlling persons who may be subject to liability arising out of
any claim in respect of which indemnity may be sought under this Section 10 if,
the named parties to any such action, suit or proceeding (including any
impleaded parties) include both an indemnified party (and/or its officers,
employees, directors and each person who controls the indemnified party within
the meaning of the Securities Act) and the indemnifying party and the
indemnified party shall have been advised by its counsel that representation of
both the indemnified party (and/or its officers, employees, directors and each
person who controls the indemnified party within the meaning of the Securities
Act) and the indemnifying party would be inappropriate under applicable
standards of professional conduct (whether or not such representation by the
same counsel has been proposed) and in the reasonable judgment of the
indemnified party, it is advisable for the indemnified party and its directors,
officers, employees and controlling persons to be jointly represented by
separate counsel, then in that event the fees and expenses of one such separate
counsel shall be paid by the indemnifying party. No indemnifying party shall (i)
without the prior written consent of the indemnified parties (which consent
shall not be unreasonably withheld), settle or compromise or consent to the
entry of any judgment with respect to any pending or threatened claim, action,
suit or proceeding in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement of any such action

effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with the consent of the indemnifying party or if there
is a final judgment of the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment.

               (d) If the indemnification provided for in this Section 10 shall
for any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 10(a) or 10(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company and the Investment Adviser (treated jointly as one
person for this purpose) on the one hand and the Underwriters on the other from
the offering of the Tortoise Notes or (ii) if the allocation provided by clause
(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company and the Investment Adviser
(treated jointly as one person for this purpose) on the one hand and the
Underwriters on the other with respect to the statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations. The relative benefits
received by the Company and the Investment Adviser (treated jointly as one
person for this purpose) on the one hand and the Underwriters on the other with
respect to such offering shall be deemed to be in the same proportion as the
total net proceeds from the offering of the Tortoise Notes purchased under this
Agreement (before deducting expenses) received by the Company, on the one hand,
and the total underwriting discounts and commissions received by the
Underwriters with respect to the Tortoise Notes purchased under this Agreement,
on the other hand, bear to the total gross proceeds from the offering of the
Tortoise Notes under this Agreement, in each case as set forth in the table on
the cover page of the Prospectus. The relative fault shall be determined by
reference to whether the untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Company or the Investment Adviser, on the one hand, or the
Underwriters, on the other hand, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company, the Investment Adviser and the Underwriters
agree that it would not be just and equitable if contributions pursuant to this
Section were to be determined by pro rata allocation or by any other method of
allocation which does not take into account the equitable considerations
referred to herein. The amount paid or payable by an indemnified party as a
result of the loss, claim, damage or liability, or action in respect thereof,
referred to above in this Section shall be deemed to include, for purposes of
this Section 10(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 10(d), the Underwriters
shall not be required to contribute any amount in excess of the total
underwriting discounts and commissions received by such Underwriter. No person
guilty of fraudulent misrepresentation (within the meaning

of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

     Section 11. Defaulting Underwriters. If, on the Delivery Date, any
Underwriter defaults in the performance of its obligations under this Agreement,
the remaining non-defaulting Underwriters shall be obligated to purchase the
Tortoise Notes which the defaulting Underwriter agreed but failed to purchase on
the Delivery Date in the respective proportions which the aggregate principal
amount of Tortoise Notes set forth opposite the name of each remaining
non-defaulting Underwriter in Schedule I hereto bears to the total aggregate
principal amount of Tortoise Notes set forth opposite the names of all the
remaining non-defaulting Underwriters in Schedule I hereto; provided, however,
that the remaining non-defaulting Underwriters shall not be obligated to
purchase any amount of the Tortoise Notes on the Delivery Date if the aggregate
principal amount of Tortoise Notes which the defaulting Underwriter or
Underwriters agreed but failed to purchase on such date exceeds 9.09% of the
aggregate principal amount of Tortoise Notes to be purchased on the Delivery
Date, and any remaining non-defaulting Underwriter shall not be obligated to
purchase more than 110% of the aggregate principal amount of Tortoise Notes
which it agreed to purchase on the Delivery Date pursuant to the terms of
Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting
Underwriters, shall have the right, but shall not be obligated, to purchase, in
such proportion as may be agreed upon among them, the total aggregate principal
amount of Tortoise Notes to be purchased on such Delivery Date. If the remaining
Underwriters do not elect to purchase the Tortoise Notes which the defaulting
Underwriter or Underwriters agreed but failed to purchase on the Delivery Date,
this Agreement shall terminate without liability on the part of any
non-defaulting Underwriter or the Company, except that the Company will continue
to be liable for the payment of expenses to the extent set forth in Sections 7
and 13. As used in this Agreement, the term "Underwriter" includes, for all
purposes of this Agreement unless the context requires otherwise, any party not
listed in Schedule I hereto who, pursuant to this Section 11, purchases Tortoise
Notes which a defaulting Underwriter agreed but failed to purchase.

     Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default. If other
Underwriters are obligated or agree to purchase the Tortoise Notes of a
defaulting or withdrawing Underwriter, either the non-defaulting Underwriters or
the Company may postpone the Delivery Date for up to seven full business days in
order to effect any changes that in the opinion of counsel for the Company or
counsel for the Underwriters may be necessary in the Registration Statement, the
Prospectus or in any other document or arrangement.

     Section 12. Termination. The obligations of the Underwriters hereunder may
be terminated by the Representative on behalf of the Underwriters by notice
given to and received by the Company prior to delivery of and payment for the
Tortoise Notes if, prior to that time, any of the events described in Sections
9(j) or 9(n), shall have occurred or if the Underwriters shall decline to
purchase the Tortoise Notes for any reason permitted under this Agreement.

     Section 13. Reimbursement of Underwriters' Expenses. If (a) the Company
shall fail to tender the Tortoise Notes for delivery to the Underwriters by
reason of any failure, refusal or inability on the part of the Company to
perform any agreement on its part to be performed, or because any other
condition of the Underwriters' obligations hereunder required to be fulfilled by
the Company is not fulfilled or (b) the Underwriters decline to purchase the
Tortoise Notes because of a failure by the Company or the Investment Adviser to
perform their respective obligations under this Agreement, the Company shall
reimburse the Underwriters for all reasonable out-of-pocket expenses (including
fees and disbursements of counsel) incurred by the Underwriters in connection
with this Agreement and the proposed purchase of the Tortoise Notes, and upon
demand the Company shall pay the full amount thereof to the Underwriters.

     Section 14. Information Furnished by Underwriters. The Underwriters
severally confirm that the information appearing in the list of names of each of
the Underwriters under the caption "Underwriting" in the Preliminary Prospectus
