                             Underwriting Agreement

To the Representatives of the
   several Underwriters named in
   the respective Pricing Agreements
   hereinafter described.

                                                ________ __, 1999

Dear Sirs:

            From time to time Southern Indiana Gas and Electric Company, an
Indiana corporation (the "Company"), proposes to enter into one or more Pricing
Agreements (each a "Pricing Agreement") in the form of Annex I hereto, with such
additions and deletions as the parties thereto may determine, and, subject to
the terms and conditions stated herein and therein, to issue and sell to the
firms named in Schedule I to the applicable Pricing Agreement (such firms
constituting the "Underwriters" with respect to such Pricing Agreement and the
Senior Notes specified therein) certain of its Senior Notes (the "Senior
Notes"). Senior Notes specified in Schedule II to a Pricing Agreement are
hereinafter referred to as the "Designated Senior Notes" with respect to such
Pricing Agreement.

            The Senior Notes are to be issued under a governing indenture
(together with any supplements, the "Senior Note Indenture") each between the
Company and ___________________, as Trustee (the "Senior Note Trustee"), in
substantially the form heretofore delivered to the Representatives. Until the
Release Date (as defined in the Senior Note Indenture), the Senior Notes will be
secured by one or more series of Senior Note First Mortgage Bonds (as defined in
the Senior Note Indenture) issued and delivered by the Company to the Senior
Note Trustee. On the Release Date, the Senior Notes will cease to be secured by
the Senior Note First Mortgage Bonds and will become unsecured obligations of
the Company. The Senior Note First Mortgage Bonds securing the Senior Notes will
be issued under the Company's Mortgage and Deed of Trust, dated as of April 1,
1932, with Bankers Trust Company, New York, New York, as Trustee (the "Mortgage
Trustee"), as heretofore supplemented and amended by


                                                                               2


Supplemental Indentures and as the same may be further supplemented by a
Supplemental Indenture relating to the Senior Note First Mortgage Bonds (such
Mortgage and Deed of Trust, as so supplemented and amended and as to be
supplemented and amended being hereinafter referred to as the "Mortgage" and
such Supplemental Indenture being referred to as the "Supplemental Indenture").
The terms and rights of the Senior Notes shall be as specified in the Pricing
Agreement relating thereto and specified in or pursuant to the Senior Note
Indenture.

            1. Particular sales of Designated Senior Notes may be made from time
to time to the Underwriters of such Senior Notes for whom the firms designated
as representatives of the Underwriters of such Senior Notes in the Pricing
Agreement relating thereto will act as representatives (the "Representatives").
The term "Representatives" also refers to a single firm acting as sole
representative of the Underwriters and to Underwriters who act without any firm
being designated as their representative. This Agreement shall not be construed
as an obligation of the Company to sell any of the Senior Notes to the
Underwriters or as an obligation of any of the Underwriters to purchase any of
the Senior Notes. The obligation of the Company to issue and sell any of the
Senior Notes and the obligation of any of the Underwriters to purchase any of
the Senior Notes shall be evidenced by the Pricing Agreement with respect to the
Designated Senior Notes specified therein. Each Pricing Agreement shall specify
the aggregate principal amount of such Designated Senior Notes, the public
offering price of such Designated Senior Notes, the purchase price to the
Underwriters of such Designated Senior Notes, the names of the Underwriters of
such Designated Senior Notes, the names of the Representatives of such
Underwriters and the principal amount of such Designated Senior Notes to be
purchased by each Underwriter, and shall set forth the date, time and manner of
delivery of such Designated Senior Notes and payment therefor. The Pricing
Agreement shall also specify (to the extent not set forth in the Senior Note
Indenture, the Registration Statement (as defined in Section 2 hereof) and the
Prospectus (as defined in Section 2 hereof)) the terms of such Designated Senior
Notes. A Pricing Agreement shall be in the form of an executed writing (which
may be in counterparts), and may be evidenced by an exchange of telegraphic
communications or communications transmitted through any other rapid
transmission device designed to produce a written record of communications
transmitted. The obligations of the Underwriters under this Agreement and each
Pricing Agreement shall be several and not joint.

            2. The Company represents and warrants to, and agrees with, each of
the Underwriters that:

            (a) A registration statement in respect of the Senior Notes has been
      filed with the Securities and Exchange Commission (the "Commission"); such

      the purchase and distribution of the Senior Notes by the Underwriters;

            (k) Except as set forth in the Prospectus, there are no legal,
      governmental or administrative proceedings pending to which the Company or
      any of its subsidiaries is a party or of which any property of the Company
      or any of its subsidiaries is the subject, which if determined adversely
      to the Company or any of its subsidiaries, would individually or in the
      aggregate have a material adverse effect on the general affairs, financial
      position, stockholders' equity or results of operations of the Company and

      the business or operations of the Company or any of its subsidiaries will
      be affected by the Year 2000 Problem and has completed or is in the
      process of completing measures which are designed to address the Year 2000
      Problem. As a result of such review and such measures, the Company has no
      reason to believe, and does not believe, that the Year 2000 Problem will
      have a material adverse effect on the general affairs, management, the
      current or future consolidated financial position, business prospects,
      stockholders' equity or results of operations of the Company and its
      subsidiaries or result in any material loss or interference with the
      Company's business or operations. The "Year 2000 Problem" as used herein
      means any significant risk that computer hardware or software used in the
      receipt, transmission, processing, manipulation, storage, retrieval,
      retransmission or other utilization of data or in the operation of
      mechanical or electrical systems of any kind will not, in the case of
      dates or time periods occurring after December 31, 1999, function at least
      as effectively as in the case of dates or time periods occurring prior to
      January 1, 2000.

Designated Senior Notes and authorization by the Representatives of the release
of such Designated Senior Notes, the several Underwriters propose to offer such
Designated Senior Notes for sale upon the terms and conditions set forth in the
Prospectus as amended and supplemented.

            4. Designated Senior Notes to be purchased by each Underwriter

extent practicable, and in such authorized denominations and registered in such
names as the Representatives may request upon at least forty-eight hours' prior
notice to the Company, shall be delivered by or on behalf of the Company to the

      pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act for so
      long as the delivery of a prospectus is required in connection with the
      offering or sale of such Senior Notes, and during such same period to

      initiation or threatening of any proceeding for any such purpose, or of
      any request by the Commission for the amending or supplementing of the
      Registration Statement or Prospectus or for additional information; and in

            as an exhibit to the Registration Statement or required to be
            incorporated by reference into the Prospectus or required to be
            described in the Registration Statement or the Prospectus which are

            binding instrument, enforceable in accordance with its terms, except
            as the same may be limited by laws of the States of Indiana and
            Kentucky, where the property covered thereby is located, relating to
            or affecting the remedies for the enforcement of the security
            provided for therein, or as the same may be limited by bankruptcy,
            insolvency, reorganization and other laws of general applicability
            relating to or affecting creditors' rights and to general equity
            principles; and the Mortgage has been duly qualified under the Trust
            Indenture Act, and all taxes and fees required to be paid with
            respect to the execution and delivery of the Mortgage, the filing
            and recording of the Mortgage and issuance of the Senior Note First
            Mortgage Bonds have been paid;

                  (vi) The documents incorporated by reference in the Prospectus
            as amended or supplemented (other than the financial statements and
            other financial data therein, as to which such counsel need express
            no opinion), when they became effective or were filed with the
            Commission, as the case may be, complied as to form in all material
            respects with the requirements of the


                                                                              19


            Act or the Exchange Act, as applicable, and the rules and
            regulations of the Commission thereunder; and they have no reason to
            believe that any of such documents, when they became effective or
            were so filed, as the case may be, contained an untrue statement of
            a material fact or omitted to state a material fact necessary in
            order to make the statements therein, in light of the circumstances
            under which they were made when such documents were so filed, not
            misleading; and

                  (vii) The Registration Statement has become effective under
            the Act and to the best knowledge of such counsel no stop order
            suspending the effectiveness of the Registration Statement has been
            issued and no proceedings for that purpose have been instituted or,
            to the knowledge of such counsel, threatened by the Commission; and

                  (viii) The Registration Statement and the Prospectus as
            amended or supplemented and any further amendments and supplements
            thereto made by the Company prior to the Time of Delivery for the
            Designated Senior Notes (other than the financial statements and
            other financial data therein, as to which such counsel need express
            no opinion) comply as to form in all material respects with the
            requirements of the Act and the Trust Indenture Act and the rules
            and regulations thereunder; they have no reason to believe that, as
            of its effective date, the Registration Statement or any further
            amendment thereto made by the Company prior to the Time of Delivery
            (other than the financial statements and other financial data
            therein, as to which such counsel need express no opinion) contained
            an untrue statement of a material fact or omitted to state a
            material fact required to be stated therein or necessary to make the
            statements therein not misleading or that, as of its date, the
            Prospectus as amended or supplemented or any further amendment or
            supplement thereto made by the Company prior to the Time of Delivery
            (other than the financial statements and other financial data
            therein, as to which such counsel need express no opinion) contained
            an untrue statement of a material fact or omitted to state a
            material fact necessary to make the statements therein, in light of
            the circumstances in which they were made, not misleading or that,
            as the Time of Delivery, either the Registration Statement or the
            Prospectus as amended or supplemented or any further amendment or
            supplement thereto made by the Company prior to the Time of Delivery
            (other than the financial statements and other financial data
            therein, as to which such counsel need express no opinion) contains
            an untrue statement of a material fact or omits to state a material
            fact


                                                                              20


            necessary to make the statement therein, in light of the
            circumstances in which they were made, not misleading; and they do
            not know of any amendment to the Registration Statement required to
            be filed or any contracts or other documents of a character required
            to be filed as an exhibit to the Registration Statement or required
            to be incorporated by reference into the Prospectus as amended or
            supplemented or required to be described in the Registration
            Statement or the Prospectus as amended or supplemented which are not
            filed or incorporated by reference or described as required;

                  (ix) The terms of the Senior Notes conform as to legal matters
            to the descriptions thereof and the statements in regard thereto
            contained in the Registration Statement and the Prospectus as
            amended or supplemented;

                  (x) The Indiana Utility Regulatory Commission has duly
            authorized the issuance and sale of the Senior Notes and the Senior
            Note First Mortgage Bonds as contemplated by this Agreement, such
            approval is in full force and effect and the time to appeal has
            expired, and no further consent, approval, authorization or order of
            or registration or qualification with any court or governmental
            agency or body is required for the issue and sale of the Senior
            Notes or the Senior Note First Mortgage Bonds or the consummation by
            the Company of the transactions contemplated by this Agreement of
            any Pricing Agreement, the Mortgage or the Senior Note Indenture,
            except such as have been obtained under the Act and the Trust
            Indenture Act and such consents, approvals, authorizations,
            registrations or qualifications as may be required under state
            securities or Blue Sky laws in connection with the purchase and
            distribution of the Senior Notes by the Underwriters; and

                  (xi) This Agreement and the Pricing Agreement relating to such
            Designated Senior Notes have been duly authorized, executed and
            delivered by the Company.

            It is understood that in rendering such opinion, Winthrop, Stimson,
Putnam & Roberts may rely as to matters of Indiana and Kentucky law upon the
opinion of Bamberger, Foreman, Oswald and Hahn;

            (e) At the Time of Delivery for such Designated Senior Notes, the
      independent accountants of the Company who have certified the financial
      statements of the Company and its subsidiaries, if any, included or
      incorporated by reference in the Registration Statement shall have
      furnished to the


                                                                              21


      Representatives a letter dated such Time of Delivery in form and substance
      satisfactory to the Representatives, to the effect set forth in Annex II
      hereto and as to such other matters as the Representatives may reasonably
      request;

            (f) Other than as set forth or contemplated in the Prospectus as
      amended or supplemented (i) the Company shall not have sustained since the
      date of the latest audited financial statements included or incorporated
      by reference in the Prospectus as amended or supplemented any loss or
      interference with its business whether or not insured against, and (ii)
      since the respective dates as of which information is given in the
      Prospectus as amended or supplemented there shall not have been any change
      in the capital stock, long-term debt or long-term lease obligations or
      commitments of the Company (other than occasioned by shares of common
      stock having been issued pursuant to the Company's Dividend Reinvestment
      and other stock plans) or any change, or any development involving a
      prospective change, in or affecting the general affairs, management,
      financial position, stockholders' equity or results of operations of the
      Company, the effect of which in any such case described in Clause (i) or
      (ii) is in the judgment of the Representatives so material and adverse as
      to make it impracticable or inadvisable to proceed with the public
      offering or the delivery of the Designated Senior Notes on the terms and
      in the manner contemplated in the Prospectus as amended or supplemented;

            (g) On or after the date of the Pricing Agreement relating to the
      Designated Senior Notes, (i) no downgrading shall have occurred in the
      rating accorded the Company's [senior] debt securities by any "nationally
      recognized statistical rating organization," as that term is defined by
      the Commission for purposes of Rule 436(g)(2) under the Act and (ii) no
      such organization shall have publicly announced that it has under
      surveillance or review, with possible negative implications, its rating of
      any of the Company's debt securities;

            (h) On or after the date of the Pricing Agreement relating to the
      Designated Senior Notes there shall not have occurred any of the
      following: (i) a suspension or material limitation in trading in
      securities generally on the New York Stock Exchange; (ii) a general
      moratorium on commercial banking activities in New York declared by either
      Federal or New York State authorities; or (iii) the outbreak or escalation
      of hostilities involving the United States or the declaration by the
      United States of a national emergency or war if the effect of any such
      event specified in this Clause (iii) in the judgment of the
      Representatives makes it impracticable or inadvisable to proceed with the
      public offering or the delivery of the Designated Senior Notes on


                                                                              22


      the terms and in the manner contemplated in the Prospectus as amended or
      supplemented;

            (i) The Company shall have complied with the provisions of Section
      5(c) hereof with respect to the furnishing of prospectuses on the New York
      Business Day next succeeding the date of this Agreement; and

            (j) The Company shall have furnished or caused to be furnished to
      the Representatives at the Time of Delivery for the Designated Senior
      Notes a certificate or certificates of officers of the Company
      satisfactory to the Representatives as to the accuracy of the
      representations and warranties of the Company herein at and as of such
      Time of Delivery, as to the performance by the Company of all of its
      obligations hereunder to be performed at or prior to such Time of
      Delivery, as to the matters set forth in subsections (a) and (f) of this
      Section and as to such other matters as the Representatives may reasonably
      request.

      8. (a) The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Senior Notes, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse each Underwriter for any legal or other expenses reasonably incurred
by such Underwriter in connection with investigating or defending any such
action or claim as such expenses are incurred; provided, however, that the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus, any preliminary prospectus supplement, the Registration Statement,
the Prospectus as amended or supplemented and any other prospectus relating to
the Senior Notes, or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
of Designated Senior Notes through the Representatives expressly for use in the
Prospectus as amended or supplemented relating to such Senior Notes; and
provided further, that the Company shall not be liable to any Underwriter under
the indemnity agreement in this subsection (a) with respect to any Preliminary
Prospectus to the extent that any such loss, claim, damage or liability of such
Underwriter results from the fact


                                                                              23


that such Underwriter sold Designated Senior Notes to a person as to whom it
shall be established that there was not sent or given, at or prior to the
written confirmation of such sale, a copy of the Prospectus in any case where
such delivery is required by the Act if such Underwriter failed to make
reasonable efforts generally consistent with the then prevailing industry
practice and the Company has previously furnished copies thereof in sufficient
quantity and on a timely basis to such Underwriter and the loss, claim, damage
or liability of such Underwriter results from an untrue statement or omission of
a material fact contained in the Preliminary Prospectus which was identified in
writing to such Underwriter and corrected in the Prospectus.

            (b) Each Underwriter will indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which the Company may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, any preliminary prospectus supplement,
the Registration Statement, the Prospectus as amended or supplemented and any
other prospectus relating to the Senior Notes, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Senior Notes, or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representatives expressly for use therein; and will reimburse the Company for
any legal or other expenses reasonably incurred by the Company in connection
with investigating or defending any such action or claim as such expenses are
incurred.

            (c) Promptly after receipt by an indemnified party under Subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel


                                                                              24


satisfactory to such indemnified party (who shall not, except with the consent
of the indemnified party, be counsel to the indemnifying party), and, after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party under such subsection for any legal expenses of other
counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation.

            (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
Subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the Company on the one hand and the Underwriters of the
Designated Senior Notes on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations, including relative benefit. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or such Underwriters on the other, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Subsection (d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Subsection (d). The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions in respect thereof) referred to above in this
Subsection (d) shall be deemed to include 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 Subsection (d),
no Underwriter shall be required to contribute any amount in excess of the
amount by which the total price at which the applicable Designated Senior Notes
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be


                                                                              25


entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The obligations of the Underwriters of Designated Senior
Notes in this Subsection (d) to contribute are several in proportion to their
respective underwriting obligations with respect to such Senior Notes and not
joint.

            (e) The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company and to each
person, if any, who controls the Company within the meaning of the Act.

            9. (a) If any Underwriter shall default in its obligation to
purchase the Designated Senior Notes which it has agreed to purchase under the
Pricing Agreement relating to such Designated Senior Notes, the Representatives
may in their discretion arrange for themselves or another party or other parties
to purchase such Designated Senior Notes on the terms contained herein. If
within thirty-six hours after such default by any Underwriter the
Representatives do not arrange for the purchase of such Designated Senior Notes,
then the Company shall be entitled to a further period of thirty-six hours
within which to procure another party or other parties satisfactory to the
Representatives to purchase such Designated Senior Notes on such terms. In the
event that, within the respective prescribed period, the Representatives notify
the Company that they have so arranged for the purchase of such Designated
Senior Notes, or the Company notifies the Representatives that it has so
arranged for the purchase of such Designated Senior Notes, the Representatives
or the Company shall have the right to postpone the Time of Delivery for such
Designated Senior Notes for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Registration
Statement or the Prospectus as amended or supplemented, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments or supplements to the Registration Statement or the Prospectus which
in the opinion of the Representatives may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section 9 with like effect as if such person had originally been a
party to the Pricing Agreement relating to such Designated Senior Notes.

            (b) If, after giving effect to any arrangements for the purchase of
the Designated Senior Notes of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in Subsection (a) above, the
aggregate


                                                                              26


principal amount of such Designated Senior Notes which remains unpurchased does
not exceed one-eleventh of the aggregate principal amount of the Designated
Senior Notes, then the Company shall have the right to require each
non-defaulting Underwriter to purchase the principal amount of Designated Senior
Notes which such Underwriter agreed to purchase under the Pricing Agreement
relating to such Designated Senior Notes and, in addition, to require each
non-defaulting Underwriter to purchase its pro rata share (based on the
principal amount of Designated Senior Notes which such Underwriter agreed to
purchase under such Pricing Agreement) of the Designated Senior Notes of such
defaulting Underwriter or Underwriters for which such arrangements have not been
made; but nothing herein shall relieve a defaulting Underwriter from liability
for its default.

            (c) If, after giving effect to any arrangements for the purchase of
the Designated Senior Notes of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in Subsection (a) above, the
aggregate principal amount of Designated Senior Notes which remains unpurchased
exceeds one-eleventh of the aggregate principal amount of the Designated Senior
Notes, as referred to in Subsection (b) above, or if the Company shall not
exercise the right described in Subsection (b) above to require non-defaulting
Underwriters to purchase Designated Senior Notes of a defaulting Underwriter or
Underwriters, then the Pricing Agreement relating to such Designated Senior
Notes shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company, except for the expenses to be borne
by the Company and the Underwriters as provided in Section 6 hereof and the
indemnity and contribution agreements in Section 8 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

            10. The respective indemnities, agreements, representations,
warranties and other statements of the Company and the several Underwriters, as
set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of any Underwriter or any controlling person of any Underwriter, or the
Company, or any officer or director or controlling person of the Company, and
shall survive delivery of and payment for the Senior Notes.

            11. If any Pricing Agreement shall be terminated pursuant to Section
9 hereof, the Company shall not then be under any liability to any Underwriter
with respect to the Designated Senior Notes covered by such Pricing Agreement
except as provided in Section 6 and Section 8 hereof; but, if for any other
reason Designated Senior Notes are not delivered by or on behalf of the Company
as provided herein, the Company will reimburse the Underwriters through the
Representatives for all out-of-pocket


                                                                              27


expenses approved in writing by the Representatives, including fees and
disbursements of counsel, reasonably incurred by the Underwriters in making
preparations for the purchase, sale and delivery of such Designated Senior
Notes, but the Company shall then be under no further liability to any
Underwriter with respect to such Designated Senior Notes except as provided in
Section 6 and Section 8 hereof.

            12. In all dealings hereunder, the Representatives of the
Underwriters of Designated Senior Notes shall act on behalf of each of such
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by such Representatives jointly or by such of the Representatives, if any,
as may be designated for such purpose in the Pricing Agreement.

            All statements, requests, notices and agreements hereunder shall be
in writing, and if to the Underwriters shall be delivered or sent by mail or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Company shall be delivered or sent by mail or
facsimile transmission to the address of the Company set forth in the
Registration Statement: Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by
registered mail to such Underwriter at its address provided to the Company for
the purpose of notices pursuant to such Section 8(c).

            13. This Agreement and each Pricing Agreement shall be binding upon,
and inure solely to the benefit of, the Underwriters, the Company and, to the
extent provided in Section 8 and Section 10 hereof, the officers and directors
of the Company and each person who controls the Company or any Underwriter, and
their respective heirs, executors, administrators, successors and assigns, and
no other person shall acquire or have any right under or by virtue of this
Agreement or any such Pricing Agreement. No purchaser of any of the Senior Notes
from any Underwriter shall be deemed a successor or assign by reason merely of
such purchase.

            14. Time shall be of the essence of each Pricing Agreement. As used
herein, "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business. As used herein, "New York Business Day"
shall mean any day when the New York Stock Exchange is open for business.

            15. THIS AGREEMENT AND EACH PRICING AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

            amounts in the audited consolidated financial statements included or
            incorporated by reference in the Company's Annual Report on Form
            10-K for the most recent fiscal year;

            year;
