                                                                  August 7, 2003

Goldman, Sachs & Co.,
    As representative of the several Underwriters
      named in Schedule I hereto,
c/o Goldman, Sachs & Co.,
85 Broad Street,
New York, New York 10004

Ladies and Gentlemen:

     Vectren  Corporation,  an Indiana  corporation (the  "Company"),  proposes,
subject  to the terms and  conditions  stated  herein,  to issue and sell to the
Underwriters  named in Schedule I hereto (the  "Underwriters")  an  aggregate of
6,500,000  shares of common stock, no par value per share ("Common  Stock"),  of
the Company (the "Firm Shares") and, at the election of the Underwriters,  up to
975,000 additional shares of Common Stock of the Company (the "Optional Shares")
(the Firm Shares and the Optional Shares that the Underwriters elect to purchase
pursuant to Section 2 hereof being collectively called the "Shares").

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

     (a) A  registration  statement  on Form  S-3  (File  No.  333-104186)  (the
"Initial  Registration  Statement") in respect of certain securities,  including
the Shares,  has been filed by the Company and certain  other  entities with the
Securities and Exchange Commission (the "Commission").  The Initial Registration
Statement and any post-effective  amendment thereto, each in the form heretofore
delivered to Goldman, Sachs & Co., and, excluding exhibits thereto but including
all documents  incorporated by reference in the prospectus contained therein, to
Goldman,  Sachs & Co.  for each of the other  Underwriters,  have been  declared
effective by the Commission in such form;  other than a  registration  statement
increasing  the size of the offering (a "Rule 462(b)  Registration  Statement"),
filed  pursuant to Rule 462(b) under the Securities Act of 1933, as amended (the
"1933 Act"),  which became effective upon filing, no other document with respect
to the Initial  Registration  Statement  or document  incorporated  by reference
therein has heretofore been filed with the Commission.  No stop order suspending
the  effectiveness of the Initial  Registration  Statement,  any  post-effective
amendment thereto or the Rule 462(b) Registration  Statement has been issued and
no  proceeding  for  that  purpose  has  been  initiated  or  threatened  by the
Commission  (any  preliminary  prospectus  included in the Initial  Registration
Statement or filed with the Commission  pursuant to Rule 424(a) of the rules and
regulations of the Commission under the 1933 Act (the "1933 Act Regulations") is
hereinafter called a "Preliminary Prospectus".  The various parts of the Initial
Registration  Statement and the Rule 462(b) Registration Statement including all
exhibits  thereto and including the documents  incorporated  by reference in the
prospectus contained in the Initial Registration Statement at the time such part
of the Initial Registration  Statement became effective,  each as amended at the
time such part of the Initial  Registration  Statement  became effective or such
part of the Rule 462(b) Registration Statement became effective, are hereinafter
collectively called the "Registration  Statement" and such final prospectus,  in
the form first filed  pursuant to Rule 424(b) under the 1933 Act, is hereinafter
called the "Prospectus".  Any reference herein to any Preliminary  Prospectus or
the Prospectus  shall include the documents  incorporated  by reference  therein
pursuant  to Item 12 of Form  S-3  under  the 1933  Act,  as of the date of such
Preliminary  Prospectus or Prospectus,  as the case may be. Any reference to any
amendment or supplement to any Preliminary  Prospectus or the Prospectus include
any documents filed after the date of such Preliminary Prospectus or Prospectus,
as the case may be, under the  Securities  Exchange Act of 1934, as amended (the
"1934 Act"),  and  incorporated by reference in such  Preliminary  Prospectus or
Prospectus,  as  the  case  may  be.  Any  reference  to  any  amendment  to the
Registration Statement shall be deemed to refer to and include any annual report
of the Company  filed  pursuant to Section  13(a) or 15(d) of the 1934 Act after
the effective date of the Initial Registration Statement that is incorporated by
reference in the Registration Statement.

     (b) No order preventing or suspending the use of any Preliminary Prospectus
has been issued by the Commission,  and each Preliminary Prospectus, at the time
of filing thereof, conformed in all material respects to the requirements of the
1933 Act and the 1933 Act  Regulations,  and did not contain an 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,  in the  light of the
circumstances  under which they were made, not  misleading;  provided,  however,
that this  representation  and  warranty  shall not apply to any  statements  or
omissions made in reliance upon and in conformity with information  furnished in
writing to the Company by an Underwriter through Goldman,  Sachs & Co. expressly
for use therein.

     (c) The documents  incorporated by reference in the  Prospectus,  when they
became  effective  or were  filed  with  the  Commission,  as the  case  may be,
conformed in all material respects to the requirements of the 1933 Act, the 1933
Act Regulations,  1934 Act and the rules and regulations of the Commission under
the  1934 Act (the  "1934  Act  Regulations),  as  applicable,  and none of such
documents 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.  Any further  documents  so filed and  incorporated  by
reference in the Prospectus or any further amendment or supplement thereto, when
such documents  become  effective or are filed with the Commission,  as the case
may be, will conform in all material  respects to the  requirements  of the 1933
Act,  1933 Act  Regulations,  the 1934  Act and the  1934  Act  Regulations,  as
applicable,  and will not contain an 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;  provided,  however, that this representation
and warranty  shall not apply to any  statements  or omissions  made in reliance
upon and in conformity with  information  furnished in writing to the Company by
an Underwriter through Goldman, Sachs & Co. expressly for use therein.

     (d) The Registration Statement conforms, and the Prospectus and any further
amendments or supplements to the  Registration  Statement or the Prospectus will
conform,  in all material  respects to the  requirements of the 1933 Act and the
1933 Act  Regulations  and do not and will not, as of the  applicable  effective
date as to the Registration  Statement and any amendment thereto,  and as of the
applicable  filing date as to the  Prospectus  and any  amendment or  supplement
thereto,  contain  an 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; provided, however, that this representation and warranty
shall not apply to any  statements  or  omissions  made in reliance  upon and in
conformity  with  information   furnished  in  writing  to  the  Company  by  an
Underwriter through Goldman, Sachs & Co. expressly for use therein.

     (e) The  accountants  that  audited the  Company's  consolidated  financial
statements  and  supporting  schedules  thereto  included  in  the  Registration
Statement and the  Prospectus,  as specified  therein,  are  independent  public
accountants  of the  Company  as  required  by the  1933  Act and the  1933  Act
Regulations.

     (f) The  consolidated  financial  statements  included in the  Registration
Statement and the  Prospectus,  together  with the related  schedules and notes,
present  fairly the  financial  position  of the  Company  and its  consolidated
subsidiaries   at  the  dates   indicated  and  the  statement  of   operations,
stockholders'  equity  and  cash  flows  of the  Company  and  its  consolidated
subsidiaries  for the periods  specified.  Such financial  statements  have been
prepared in conformity with generally accepted  accounting  principles  ("GAAP")
applied on a consistent  basis throughout the periods  involved.  The supporting
schedules,  if any,  included in the  Registration  Statement and the Prospectus
present  fairly in accordance  with GAAP the  information  required to be stated
therein. The selected financial data and the summary financial  information,  if
any,  included in the Registration  Statement and the Prospectus  present fairly
the information  shown therein and have been compiled on a basis consistent with
that  of  the  audited   consolidated   financial  statements  included  in  the
Registration  Statement  and the  Prospectus.  The  Company is not  required  to
include any pro forma financial statements in the Registration  Statement or the
Prospectus  under  the  1933 Act or the 1933  Act  Regulations  or any  document
required  to be filed  with the  Commission  under  the 1934 Act or the 1934 Act
Regulations.

     (g) The authorized,  issued and outstanding  shares of capital stock of the
Company are as set forth in the Prospectus in the column entitled "Actual" under
the caption  "Capitalization"  (except for subsequent issuances thereof, if any,
pursuant to this Agreement or pursuant to the exercise of options or pursuant to
various employee and director compensation plans, the dividend reinvestment plan
or 401(k) plan referred to in the Prospectus).  All of the issued by the Company
and outstanding shares of capital stock of the Company have been duly authorized
and validly  issued by the Company  and are fully paid and  non-assessable,  and
none of such shares were issued in violation of the  preemptive or other similar
rights of any securityholder of the Company.

     (h)  Since the  respective  dates as of which  information  is given in the
Registration  Statement and the Prospectus,  except as otherwise stated therein,
(A) there has not been any change in the capital stock or long-term  debt of the
Company  or any of its  subsidiaries  or any  material  adverse  change,  or any
development involving a prospective material adverse change, in or affecting the
general affairs, management,  financial position, stockholders' equity or result
of operations of the Company and its subsidiaries  considered as one enterprise,
whether or not arising in the ordinary  course of business (a "Material  Adverse
Effect"), (B) there have been no transactions entered into by the Company or any
of its subsidiaries,  other than those in the ordinary course of business, which
are material with respect to the Company and its subsidiaries  considered as one
enterprise,  and (C) except for regular quarterly  dividends on the Common Stock
in amounts per share that are consistent  with past practice,  there has been no
dividend or  distribution  of any kind declared,  paid or made by the Company on
any class of its capital stock.

     (i) The Company  has been duly  incorporated  and is validly  existing as a
corporation  under the laws of the State of Indiana and has power and  authority
(corporate  and other) to own,  lease and operate its  properties and to conduct
its business as described in the Prospectus and to execute,  deliver and perform
this Agreement and consummate the transactions  contemplated herein. The Company
is duly qualified as a foreign  corporation to transact  business and is in good
standing in each other  jurisdiction  in which such  qualification  is required,
whether by reason of the  ownership  or leasing of  property  or the  conduct of
business, except where the failure so to qualify or to be in good standing would
not result in a Material Adverse Effect.

     (j) Each  "significant  subsidiary" of the Company (as such term is defined
in  Rule  1-02  of  Regulation  S-X)  (each,  a  "Significant  Subsidiary"  and,
collectively,  the "Significant  Subsidiaries")  is set forth on Schedule II and
has been  duly  organized  and is  validly  existing  as a  corporation  in good
standing,  where  applicable,   under  the  laws  of  the  jurisdiction  of  its
incorporation,  has power and authority  (corporate and other) to own, lease and
operate  its  properties  and  to  conduct  its  business  as  described  in the
Prospectus and is duly qualified as a foreign  corporation to transact  business
and is in good  standing in each  jurisdiction  in which such  qualification  is
required,  whether by reason of the  ownership  or leasing  of  property  or the
conduct of  business,  except  where the  failure so to qualify or to be in good
standing would not result in a Material  Adverse  Effect.  All of the issued and
outstanding  shares of capital stock of each  Significant  Subsidiary  have been
duly authorized and validly issued,  are fully paid and  non-assessable  and are
owned by the Company,  directly or through  subsidiaries,  free and clear of any
security interest, mortgage, pledge, lien, encumbrance,  claim or equity, except
for 2,277 shares of  non-voting  8.50%  redeemable  preferred  stock of Southern
Indiana Gas and  Electric  Company.  None of the  outstanding  shares of capital
stock of any  Significant  Subsidiary were issued in violation of the preemptive
or similar rights of any securityholder of such Significant Subsidiary. The only
subsidiaries of the Company are (a) the Significant Subsidiaries and (b) certain
other subsidiaries which, considered in the aggregate as a single subsidiary, do
not constitute a "significant subsidiary" (as defined in Rule 1-02 of Regulation
S-X).

     (k) This Agreement has been duly authorized,  executed and delivered by the
Company.

     (l) The Shares have been duly  authorized  by the Company for  issuance and
sale to the  Underwriters  pursuant  to this  Agreement  and,  when  issued  and
delivered  by the Company  pursuant  to this  Agreement  against  payment of the
consideration  set forth  herein,  will be  validly  issued  and fully  paid and
non-assessable. No holder of the Shares will be subject to personal liability by
reason of being such a holder.  The issuance of the Shares is not subject to the
preemptive or other similar  rights of any  securityholder  of the Company.  The
Common Stock, including the Shares,  conforms to all statements relating thereto
contained  in the  Prospectus  and such  description  conforms to the rights set
forth in the instruments defining the same.

     (m) The Shareholders Rights Agreement between the Company and National City
Bank,  as Rights Agent,  dated as of October 21, 1999 (the "Rights  Agreement"),
has been duly authorized,  executed and delivered by the Company and constitutes
a valid and legally binding  agreement of the Company,  enforceable  against the
Company  in  accordance  with  its  terms,  subject,  as to  enforceability,  to
bankruptcy,  insolvency,  reorganization and other laws of general applicability
relating to or affecting creditors' rights and to general equity principles. The
rights  under the  Rights  Agreement  to which  holders  of the  Shares  will be
entitled have been duly authorized and validly issued by the Company and conform
to all  statements  relating  thereto  contained  in  the  Prospectus  and  such
description  conforms to the rights set forth in the  instruments  defining  the
same.

     (n) Neither the Company nor any of its  subsidiaries is in violation of its
charter  or by-laws  (or other  organizational  documents)  or in default in the
performance or observance of any  obligation,  agreement,  covenant or condition
contained in any contract,  indenture,  mortgage,  deed of trust, loan or credit
agreement,  note, lease or other agreement or instrument to which the Company or
any of its  subsidiaries  is a party or by which it or any of them may be bound,
or to which any of the assets, properties or operations of the Company or any of
its subsidiaries is subject (collectively, "Agreements and Instruments"), except
for such  violations  or  defaults  that would not result in a Material  Adverse
Effect. The execution,  delivery and performance of this Agreement and any other
agreement or  instrument  entered into or issued or to be entered into or issued
by the  Company  in  connection  with the  transactions  contemplated  hereby or
thereby and the consummation of the transactions  contemplated herein and in the
Registration  Statement and the  Prospectus  (including the issuance and sale of
the Shares and the use of the proceeds  from the sale of the Shares as described
in the  Prospectus  under the caption "Use of Proceeds")  and  compliance by the
Company with its obligations  hereunder and thereunder have been duly authorized
by all  necessary  corporate  action  and do not and will not,  whether  with or
without  the  giving of  notice or  passage  of time or both,  conflict  with or
constitute a breach of, or default or Repayment  Event (as defined below) under,
or result in the creation or imposition of any lien,  charge or encumbrance upon
any assets,  properties or operations of the Company or any of its  subsidiaries
pursuant to, the Agreements and Instruments,  nor will such action result in any
violation of the  provisions of the charter or by-laws (or other  organizational
documents)  of the Company or any of its  subsidiaries  or any  applicable  law,
statute,  rule, regulation,  judgment,  order, writ or decree of any government,
government  instrumentality or court,  domestic or foreign,  having jurisdiction
over the Company or any of its subsidiaries or any of their  respective  assets,
properties or operations. As used herein, a "Repayment Event" means any event or
condition  which gives the holder of any note,  debenture  or other  evidence of
indebtedness (or any person acting on such holder's behalf) the right to require
the repurchase, redemption or repayment of all or a portion of such indebtedness
by the Company or any of its subsidiaries.

     (o) No  labor  dispute  with the  employees  of the  Company  or any of its
subsidiaries  exists or, to the knowledge of the Company,  is imminent,  and the
Company  is not aware of any  existing  or  imminent  labor  disturbance  by the
employees  of any of its  or  any  of  its  subsidiaries'  principal  suppliers,
customers or  contractors,  which,  in either  case,  would result in a Material
Adverse Effect.

     (p) Except as  otherwise  disclosed  in the  Registration  Statement or the
Prospectus,  there is no action,  suit,  proceeding,  inquiry  or  investigation
before or  brought  by any court or  governmental  agency or body,  domestic  or
foreign, now pending, or, to the knowledge of the Company,  threatened,  against
or affecting the Company or any of its subsidiaries, which (A) is required to be
disclosed  in the  Registration  Statement  and the  Prospectus  (other  than as
disclosed  therein),  (B) may  reasonably  be  expected  to result in a Material
Adverse  Effect,  or (C) may  reasonably be expected to materially and adversely
affect the  consummation of the  transactions  contemplated in this Agreement or
the  performance by the Company of its obligations  hereunder.  The aggregate of
all pending legal or governmental proceedings to which the Company or any of its
subsidiaries is a party or of which any of their respective  assets,  properties
or  operations  is the  subject  which  are not  described  in the  Registration
Statement and the Prospectus,  including ordinary routine litigation  incidental
to the business, would not result in a Material Adverse Effect.

     (q)  There  are no  franchises,  contracts  or other  documents  which  are
required to be described in the  Registration  Statement,  the Prospectus or the
documents  incorporated by reference  therein or to be filed as exhibits thereto
which have not been so described and filed as required.

     (r) No filing with, or authorization,  approval,  consent,  license, order,
registration, qualification or decree of, any court or governmental authority or
agency, domestic or foreign, is necessary or required for the performance by the
Company  of its  obligations  hereunder  or in  connection  with  the  offering,
issuance or sale of the Shares hereunder or the consummation of the transactions
contemplated by this Agreement,  except such as have been already made, obtained
or rendered, as applicable, or as may be required under state securities or blue
sky laws.

     (s) The Company  and its  subsidiaries  own or  possess,  or can acquire on
reasonable  terms,  adequate  patents,  patent  rights,  licenses,   inventions,
copyrights,  know-how  (including  trade  secrets  and other  unpatented  and/or
unpatentable  proprietary or confidential  information,  systems or procedures),
trademarks,   service  marks,  trade  names  or  other   intellectual   property
(collectively,  "Intellectual  Property") necessary to carry on the business now
operated by them, except where the failure to own, possess or acquire, singly or
in the aggregate,  would not result in a Material  Adverse  Effect.  Neither the
Company nor any of its  subsidiaries  has  received  any notice or is  otherwise
aware of any  infringement  of or conflict with  asserted  rights of others with
respect to any  Intellectual  Property  or of any facts or  circumstances  which
would render any  Intellectual  Property  invalid or  inadequate  to protect the
interest  of  the  Company  or  any  of  its  subsidiaries  therein,  and  which
infringement or conflict (if the subject of any unfavorable decision,  ruling or
finding) or invalidity or inadequacy,  singly or in the aggregate,  would result
in a Material Adverse Effect.

     (t) Except as  otherwise  disclosed  in the  Registration  Statement or the
Prospectus, (i) the Company and its subsidiaries possess such permits, licenses,
approvals,  consents  and  other  authorizations  (collectively,   "Governmental
Licenses") issued by the appropriate regulatory agencies or bodies,  domestic or
foreign,  necessary to conduct the  business now operated by them,  except where
the  non-possession  of any such  Governmental  Licenses  would not  result in a
Material Adverse Effect, (ii) the Company and its subsidiaries are in compliance
with the terms and conditions of all such  Governmental  Licenses,  except where
the  failure so to comply  would not,  singly or in the  aggregate,  result in a
Material Adverse Effect, (iii) all of the Governmental Licenses are valid and in
full force and effect,  except when the invalidity of such Governmental Licenses
or the  failure  of such  Governmental  Licenses  to be in full force and effect
would not result in a Material  Adverse  Effect and (iv) neither the Company nor
any of its subsidiaries  has received any notice of proceedings  relating to the
revocation or modification of any such Governmental Licenses which, singly or in
the  aggregate,  if the subject of an unfavorable  decision,  ruling or finding,
would result in a Material Adverse Effect.

     (u) The Company and its subsidiaries  have good and marketable title to all
material real property owned by the Company and its  subsidiaries and good title
to all other material  properties owned by them, in each case, free and clear of
all mortgages,  pledges,  liens,  security  interests,  claims,  restrictions or
encumbrances of any kind,  except (A) are otherwise  stated in the  Registration
Statement  and the  Prospectus  or (B)  those  which  do not,  singly  or in the
aggregate,  materially  affect the value of such  property and do not  interfere
with the use made and proposed to be made of such property by the Company or any
of its subsidiaries. All of the leases and subleases material to the business of
the Company and its subsidiaries,  considered as one enterprise, and under which
the  Company  or any of  its  subsidiaries  holds  properties  described  in the
Registration  Statement and the  Prospectus,  are in full force and effect,  and
neither the Company nor any of its  subsidiaries  has received any notice of any
material  claim of any sort  that has been  asserted  by anyone  adverse  to the
rights of the  Company  or any of its  subsidiaries  under any of the  leases or
subleases mentioned above, or affecting or questioning the rights of the Company
or such  Significant  Subsidiary  to the  continued  possession of the leased or
subleased premises under any such lease or sublease.

     (v) Except as  otherwise  disclosed  in the  Registration  Statement or the
Prospectus  and except as would  not,  singly or in the  aggregate,  result in a
Material Adverse Effect,  (i) neither the Company nor any of its subsidiaries is
in  violation  of any  federal,  state,  local or foreign  statute,  law,  rule,
regulation,  ordinance,  code,  policy or rule of common law or any  judicial or
administrative  interpretation thereof, including any judicial or administrative
order, consent, decree or judgment, relating to pollution or protection of human
health, the environment  (including,  without  limitation,  ambient air, surface
water, groundwater,  land surface or subsurface strata) or wildlife,  including,
without limitation,  laws and regulations  relating to the release or threatened
release  of  chemicals,  pollutants,  contaminants,  wastes,  toxic  substances,
hazardous substances, petroleum or petroleum products (collectively,  "Hazardous
Materials") or to the manufacture,  processing,  distribution,  use,  treatment,
storage,  disposal,  transport or handling of Hazardous Materials (collectively,
"Environmental  Laws"),  (ii) the Company and its subsidiaries have all permits,
authorizations  and approvals  required under any applicable  Environmental Laws
and are each in compliance with their  requirements,  (iii) there are no pending
or,  to  the  Company's  knowledge,  threatened  administrative,  regulatory  or
judicial actions,  suits,  demands,  demand letters,  claims,  liens, notices of
noncompliance  or  violation,  investigation  or  proceedings  relating  to  any
Environmental Law against the Company or any of its subsidiaries and (iv) to the
Company's knowledge,  there are no events or circumstances that might reasonably
be expected to form the basis of an order for  clean-up  or  remediation,  or an
action,  suit or proceeding by any private party or governmental body or agency,
against  or  affecting  the  Company  or  any of its  subsidiaries  relating  to
Hazardous Materials or any Environmental Laws.

     (w) There are no persons with  registration  rights or other similar rights
to have any  securities  registered on the  Registration  Statement or otherwise
registered by the Company under the 1933 Act.

     (x) The  Company is not,  and upon the  issuance  and sale of the Shares as
herein  contemplated  and the  application  of the  net  proceeds  therefrom  as
described in the Prospectus  will not be, an  "investment  company" or an entity
"controlled"  by an  "investment  company"  (as such  terms are  defined  in the
Investment Company Act of 1940, as amended (the "1940 Act")).

     (y) Each of the Company and Vectren Utility  Holdings,  Inc.  ("VUHI") is a
"holding  company" (within the meaning of the Public Utility Holding Company Act
of 1935, as amended (the "PUHC Act")) which is exempt under the PUHC Act and the
rules  and  regulations  promulgated  thereunder  from  being  required  to seek
approval  to enter  into or perform  its  obligations  under  this  Underwriting
Agreement or to issue and perform its obligations under the Shares.

     (z) The Company has  established  and  maintains  "disclosure  controls and
procedures"  (as such term is defined in Rules  13a-14 and 15d-14 under the 1934
Act (as of August 14, 2003, such term shall be defined in Rule 13a-15 and 15d-15
under the 1934 Act)) that (A) are designed to ensure that  material  information
relating to the Company, including its consolidated subsidiaries,  is made known
to the Company's  Chief  Executive  Officer and its Chief  Financial  Officer by
others  within  those  entities,  particularly  during the  periods in which the
filings made by the Company with the Commission  which it may make under Section
13(a),  13(c),  14 or 15(d) of the 1934 Act are  being  prepared,  (B) have been
evaluated for  effectiveness  as of a date within 90 days prior to the filing of
the Company's  most recent annual report filed with the  Commission  and (C) are
effective  to  perform  the  functions  for  which  they were  established.  The
Company's  accountants  and the audit committee of the board of directors of the
Company have been advised of (x) any  significant  deficiencies in the design or
operation  of internal  controls  which  could  adversely  affect the  Company's
ability to record,  process,  summarize,  and report  financial data and (y) any
fraud, whether or not material,  that involves management or other employees who
have a role in the  Company's  internal  controls.  Any material  weaknesses  in
internal controls have been identified for the Company's accountants.  Since the
date of the most recent  evaluation of such disclosure  controls and procedures,
there have been no significant  changes in internal controls or in other factors
that could  significantly  affect  internal  controls,  including any corrective
actions with regard to significant deficiencies and material weaknesses.

     2. Subject to the terms and  conditions  herein set forth,  (a) the Company
agrees  to  issue  and  sell  to  each  of the  Underwriters,  and  each  of the
Underwriters agrees, severally and not jointly, to purchase from the Company, at
a  purchase  price per share of  $22.810,  the  number of Firm  Shares set forth
opposite the name of such  Underwriter in Schedule I hereto and (b) in the event
and to the extent that the Underwriters  shall exercise the election to purchase
Optional Shares as provided below,  the Company agrees to issue and sell to each
of the  Underwriters,  and each of the  Underwriters  agrees,  severally and not
jointly, to purchase from the Company, at the purchase price per share set forth
in clause (a) of this Section 2, that  portion of the number of Optional  Shares
as to which such election shall have been exercised (to be adjusted by you so as
to  eliminate  fractional  shares)  determined  by  multiplying  such  number of
Optional  Shares by a fraction,  the numerator of which is the maximum number of
Optional  Shares  which such  Underwriter  is  entitled to purchase as set forth
opposite the name of such  Underwriter in Schedule I hereto and the  denominator
of which is the maximum number of Optional  Shares that all of the  Underwriters
are entitled to purchase hereunder.

     The  Company  hereby  grants to the  Underwriters  the right to purchase at
their election up to 975,000  Optional  Shares,  at the purchase price per share
set forth in the  paragraph  above,  for the sole  purpose of covering  sales of
shares in excess of the number of Firm Shares,  provided that the purchase price
per  Optional  Share  shall be  reduced  by an  amount  per  share  equal to any
dividends  or  distributions  declared  by the  Company  and payable on the Firm
Shares but not payable on the  Optional  Shares.  Any such  election to purchase
Optional Shares may be exercised only by written notice from you to the Company,
given  within a period of 30  calendar  days  after the date of this  Agreement,
setting  forth the aggregate  number of Optional  Shares to be purchased and the
date on which such Optional Shares are to be delivered, as determined by you but
in no event  earlier  than the First Time of  Delivery  (as defined in Section 4
hereof) or, unless you and the Company otherwise agree in writing,  earlier than
two or later than ten business days after the date of such notice.

     3. Upon the  authorization  by you of the release of the Firm  Shares,  the
several  Underwriters  propose to offer the Firm  Shares for sale upon the terms
and conditions set forth in the Prospectus.

     4.  (a) The  Shares  to be  purchased  by each  Underwriter  hereunder,  in
definitive  form, and in such  authorized  denominations  and registered in such
names as Goldman, Sachs & Co. may request upon at least forty-eight hours' prior
notice to the  Company  shall be  delivered  by or on behalf of the  Company  to
Goldman,  Sachs & Co.,  through the facilities of The  Depository  Trust Company
("DTC"), for the account of such Underwriter, against payment by or on behalf of
such  Underwriter  of the purchase  price  therefor by wire  transfer of Federal
(same-day) funds to the account specified by the Company to Goldman, Sachs & Co.
at least forty-eight  hours in advance.  The Company will cause the certificates
representing the Shares to be made available for checking and packaging at least
twenty-four  hours prior to the Time of  Delivery  with  respect  thereto at the
office of Goldman,  Sachs & Co., 85 Broad Street,  New York, New York 10004 (the
"Designated  Office").  The time and date of such delivery and payment shall be,
with respect to the Firm Shares,  9:30 a.m.,  New York City time,  on August 13,
2003 or such other time and date as  Goldman,  Sachs & Co. and the  Company  may
agree upon in writing,  and, with respect to the Optional Shares, 9:30 a.m., New
York time, on the date  specified by Goldman,  Sachs & Co. in the written notice
given by Goldman,  Sachs & Co. of the  Underwriters'  election to purchase  such
Optional  Shares,  or such other time and date as  Goldman,  Sachs & Co. and the
Company may agree upon in writing.  Such time and date for  delivery of the Firm
Shares is herein  called the "First  Time of  Delivery",  such time and date for
delivery of the Optional  Shares,  if not the First Time of Delivery,  is herein
called the "Second Time of  Delivery",  and each such time and date for delivery
is herein called a "Time of Delivery".

     (b) The  documents to be delivered at each Time of Delivery by or on behalf
of the parties hereto pursuant to Section 7 hereof,  including the cross receipt
for the  Shares  and any  additional  documents  requested  by the  Underwriters
pursuant to Section 7 hereof,  will be delivered at the offices of Sidley Austin
Brown & Wood LLP (the "Closing  Location"),  and the Shares will be delivered at
the Designated Office,  all at such Time of Delivery.  A meeting will be held at
the Closing  Location at 5:00 p.m., New York City time, on the New York Business
Day next preceding  such Time of Delivery,  at which meeting the final drafts of
the  documents  to be  delivered  pursuant  to the  preceding  sentence  will be
available for review by the parties hereto.  For the purposes of this Section 4,
"New York Business Day" shall mean each Monday, Tuesday, Wednesday, Thursday and
Friday  which  is not a day on  which  banking  institutions  in  New  York  are
generally authorized or obligated by law or executive order to close.

     5. The Company agrees with each of the Underwriters:

     (a) To prepare the  Prospectus in a form  approved by Goldman,  Sachs & Co.

than the Commission's close of business on the second business day following the
execution and delivery of this  Agreement;  to make no further  amendment or any
supplement to the Registration Statement or Prospectus prior to the last Time of
Delivery  which shall be  disapproved  by Goldman,  Sachs & Co.  promptly  after
reasonable  notice thereof;  to advise Goldman,  Sachs & Co.,  promptly after it
receives  notice  thereof,  of the time when any  amendment to the  Registration
Statement  has  been  filed  or  becomes  effective  or  any  supplement  to the
Prospectus  or any  amended  Prospectus  has been filed and to furnish  you with
copies  thereof;  to file  promptly  all  reports  and any  definitive  proxy or
information  statements  required to be filed by the Company with the Commission
pursuant to Section 13(a),  13(c), 14 or 15(d) of the 1934 Act subsequent to the
date  of the  Prospectus  and for so long as the  delivery  of a  prospectus  is
required  in  connection  with the  offering  or sale of the  Shares;  to advise
Goldman, Sachs & Co., promptly after it receives notice thereof, of the issuance
by the Commission of any stop order or of any order preventing or suspending the
use of any  Preliminary  Prospectus  or  prospectus,  of the  suspension  of the
qualification  of the Shares for  offering or sale in any  jurisdiction,  of the
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 the event of the
issuance of any stop order or of any order  preventing or suspending  the use of
any Preliminary  Prospectus or prospectus or suspending any such  qualification,
promptly to use its best efforts to obtain the withdrawal of such order;

     (b)  Promptly  from time to time to take such action as you may  reasonably
request to qualify the Shares for offering and sale under the securities laws of
such  jurisdictions as Goldman,  Sachs & Co. may request and to comply with such
laws so as to permit  the  continuance  of sales and  dealings  therein  in such
jurisdictions  for as long as may be necessary to complete the  distribution  of
the Shares,  provided  that in  connection  therewith  the Company  shall not be
required  to qualify as a foreign  corporation  or to file a general  consent to
service of process in any jurisdiction;

     (c) Prior to 10:00 A.M.,  New York City time,  on the New York Business Day
next succeeding the date of this Agreement and from time to time, to furnish the
Underwriters  with written and  electronic  copies of the Prospectus in New York
City in such quantities as Goldman,  Sachs & Co. may reasonably request,  and if
the  delivery of a  prospectus  is required at any time in  connection  with the
offering or sale of the Shares and if at such time any event shall have occurred
as a result  of which the  Prospectus  as then  amended  or  supplemented  would
include an untrue  statement  of a material  fact or omit to state any  material
fact  necessary  in order to make the  statements  therein,  in the light of the
circumstances under which they were made when such Prospectus is delivered,  not
misleading, or, if for any other reason it shall be necessary during such period
to amend or supplement the Prospectus or to file under the 1934 Act any document
incorporated by reference in the Prospectus in order to comply with the 1933 Act
or the 1934 Act, to notify you and upon your  request to file such  document and
to prepare and furnish  without charge to each  Underwriter and to any dealer in
securities  as many written and  electronic  copies as you may from time to time
reasonably  request of an amended  Prospectus or a supplement to the  Prospectus
which will correct such statement or omission or effect such compliance;

     (d)  To  make  generally  available  to  its  securityholders  as  soon  as

Act), an earnings statement of the Company and its subsidiaries  (which need not
be  audited)  complying  with  Section  11(a)  of the  1933 Act and the 1933 Act
Regulations (including, at the option of the Company, Rule 158);

     (e) During the period  beginning from the date hereof and continuing to and

purchase or otherwise transfer or dispose of, except as provided hereunder,  any
securities  of the  Company  that  are  substantially  similar  to  the  Shares,
including  but not  limited  to any  securities  that  are  convertible  into or
exchangeable  for, or that  represent the right to receive,  Common Stock or any
such substantially similar securities, file any registration statement under the
1933 Act with  respect  to any of the  foregoing  or enter  into any swap or any
other agreement or transaction that transfers,  in whole or in part, directly or
indirectly,  the economic consequences of ownership of Common Stock, whether any
such swap or  transaction  is settled by delivery of Common  Stock or such other
securities,  in cash or otherwise  (other than pursuant to employee stock option
plans  existing  on,  or upon the  conversion  or  exchange  of  convertible  or
exchangeable  securities  outstanding  as of,  the  date of this  Agreement,  or
pursuant to various  employee  and  director  compensation  plans,  the dividend
reinvestment plan or 401(k) plan), without the prior written consent of Goldman,
Sachs & Co.;

     (f) To furnish to its stockholders as soon as practicable  after the end of
each fiscal year an annual report  (including a balance sheet and  statements of
income,  stockholders' equity and cash flows of the Company and its consolidated
subsidiaries  certified  by  independent  public  accountants)  and,  as soon as
practicable  after the end of each of the first  three  quarters  of each fiscal
year  (beginning  with the fiscal quarter ending after the effective date of the
Registration  Statement),  to make  available to its  stockholders  consolidated
summary  financial  information  of the  Company and its  subsidiaries  for such
quarter in reasonable detail;

     (g)  During  a  period  of  three  years  from  the  effective  date of the
Registration  Statement,  to  furnish  to you  copies  of all  reports  or other
communications (financial or other) furnished to stockholders, and to deliver to
you (i) as soon as they are  available,  copies  of any  reports  and  financial
statements  furnished to or filed with the Commission or any national securities
exchange on which any class of  securities  of the  Company is listed,  provided
that the  Company  shall not be required to deliver  such  reports or  financial
statements to the extent that they are available on the Commission's  Electronic
Data,  Gathering,  Analysis and Retrieval system or any other publicly available
source;  and (ii)  such  additional  information  concerning  the  business  and
financial  condition  of the  Company  as you may from  time to time  reasonably
request (such financial  statements to be on a consolidated  basis to the extent
the accounts of the Company and its  subsidiaries  are  consolidated  in reports
furnished to its stockholders generally or to the Commission);

     (h) To use the net  proceeds  received  by it from the  sale of the  Shares

the purpose  described above, is granted without any fee and may not be assigned
or transferred.

     6. The Company covenants and agrees with the several  Underwriters that the
Company will pay or cause to be paid the following:  (i) the fees, disbursements
and expenses of the Company's  counsel and  accountants  in connection  with the
registration  of the  Shares  under  the  1933  Act and all  other  expenses  in
connection  with  the  preparation,  printing  and  filing  of the  Registration
Statement,  any  Preliminary  Prospectus  and the  Prospectus and amendments and
supplements  thereto  and the mailing and  delivering  of copies  thereof to the
Underwriters  and dealers;  (ii) the cost of printing or producing any Agreement

connection  with the  qualification  of the Shares for  offering  and sale under

own costs and expenses,  including  the fees of their  counsel,  stock  transfer
taxes on  resale  of any of the  Shares by them,  and any  advertising  expenses
connected with any offers they may make.

     7. The obligations of the  Underwriters  hereunder,  as to the Shares to be
delivered at each Time of Delivery,  shall be subject,  in their discretion,  to
the condition that all  representations  and warranties and other  statements of
the Company  herein are, at and as of such Time of  Delivery,  true and correct,
the  condition  that the Company  shall have  performed  all of its  obligations
hereunder theretofore to be performed, and the following additional conditions:

     (a) The Prospectus  shall have been filed with the  Commission  pursuant to
Rule 424(b) within the applicable time period  prescribed for such filing by the
rules and  regulations  under the 1933 Act and in  accordance  with Section 5(a)

effectiveness of the Registration  Statement or any part thereof shall have been
issued  and no  proceeding  for  that  purpose  shall  have  been  initiated  or
threatened by the Commission; and all requests for additional information on the
part of the  Commission  shall  have  been  complied  with  to  your  reasonable
satisfaction;

     (b) Sidley  Austin Brown & Wood LLP,  counsel for the  Underwriters,  shall
have furnished to the Underwriters such written opinion or opinions,  dated such
Time of Delivery,  in form and substance  satisfactory to the Underwriters,  and
such  counsel  shall  have  received  such  papers and  information  as they may
reasonably request to enable them to pass upon such matters;

     (c) Barnes &  Thornburg,  Indiana  counsel for the  Company,  and Ronald E.
Christian,  Executive  Vice  President,  General  Counsel and  Secretary  of the
Company, shall have furnished to you their written opinions,  dated such Time of
Delivery, in form and substance satisfactory to the Underwriters,  to the effect
set forth in Exhibits  A-1 and A-2  hereto,  respectively,  and to such  further
effect as the Underwriters may reasonably request  (including  opinions of local
counsel with respect to Vectren Energy  Delivery of Ohio, Inc. and Baker & Botts
LLP,  federal  regulatory  counsel with respect to the  exemption of the Company
from the 1935 Act.

     (d) On the date of the  Prospectus at a time prior to the execution of this
Agreement,  at 9:30  a.m.,  New York City  time,  on the  effective  date of any
post-effective  amendment to the Registration  Statement filed subsequent to the
date of this Agreement and also at each Time of Delivery,  Deloitte & Touche LLP
shall  have  furnished  to the  Underwriters  a letter  or  letters,  dated  the
respective dates of delivery thereof, in form and substance  satisfactory to the
Underwriters, to the effect set forth in Exhibit B hereto;

     (e)  Since the  respective  dates as of which  information  is given in the
Prospectus,  there  shall  not have  been any  change  in the  capital  stock or
long-term debt of the Company or any of its subsidiaries or any material adverse
change, or any development  involving a prospective  material adverse change, in
or affecting the general affairs, management,  financial position, stockholders'
equity or results of operations of the Company and its  subsidiaries  considered
as one  enterprise,  whether or not arising in the ordinary  course of business,
otherwise than as set forth or  contemplated  in the  Prospectus,  the effect of
which 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 Shares being delivered at such Time of Delivery on the terms and
in the manner contemplated in the Prospectus;

     (f) On or after the date hereof, (i) no downgrading in or withdrawal of the

by the Commission for purposes of Rule 436(g)(2)  under the 1933 Act, shall have
occurred,  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 or preferred stock;

     (g) On or after the date hereof,  there shall not have  occurred any of the
following:  (i) a suspension  or material  limitation  in trading in  securities

York  State  authorities  or a  material  disruption  in  commercial  banking or
securities  settlement  or  clearance  services in the United  States;  (iv) the
outbreak  or  escalation  of  hostilities  involving  the  United  States or the
declaration  by the  United  States of a  national  emergency  or war or (v) the
occurrence of any other calamity or crisis or any change in financial, political
or economic  conditions in the United States or elsewhere,  if the effect of any
such  event   specified   in  clause  (iv)  or  (v)  in  the   judgment  of  the
Representatives makes it impracticable or inadvisable to proceed with the public
offering or the delivery of the Shares being  delivered at such Time of Delivery
on the terms and in the manner contemplated in the Prospectus;

     (h) The  Shares to be sold at such Time of  Delivery  shall  have been duly
listed, subject to notice of issuance, on the Exchange;

     (i) The Company has obtained and  delivered  to the  Underwriters  executed
copies  of an  agreement  from  the  persons  listed  on  Schedule  III  hereto,
substantially  to the effect set forth in Exhibit C hereof in form and substance
satisfactory to you;

     (j) The Company  shall have  complied  with the  provisions of Section 5(d)

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 (e) of this Section
and as to such other matters as you 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 1933 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,  the  Registration
Statement or the Prospectus,  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,  the Registration Statement
or the  Prospectus  or any such  amendment or supplement in reliance upon and in
conformity with written information  furnished to the Company by any Underwriter
through Goldman, Sachs & Co. expressly for use therein.


     (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 1933 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,  the  Registration  Statement or the
Prospectus, 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, the Registration Statement or the Prospectus or any such
amendment  or  supplement  in  reliance  upon  and in  conformity  with  written
information furnished to the Company by such Underwriter through Goldman,  Sachs
& Co. 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  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. No indemnifying party shall, without the written consent
of the indemnified party,  effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or  threatened  action or
claim  in  respect  of  which  indemnification  or  contribution  may be  sought
hereunder  (whether or not the indemnified party is an actual or potential party
to such action or claim)  unless such  settlement,  compromise  or judgment  (i)
includes an  unconditional  release of the indemnified  party from all liability
arising out of such action or claim and (ii) does not include a statement  as to
or an  admission of fault,  culpability  or a failure to act, by or on behalf of
any indemnified party.

     (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  benefits  received
by the  Company  on the one  hand and the  Underwriters  on the  other  from the
offering of the Shares. If, however,  the allocation provided by the immediately
preceding  sentence is not  permitted by  applicable  law or if the  indemnified
party failed to give the notice required under  subsection (c) above,  then each
indemnifying  party  shall  contribute  to such  amount  paid or payable by such
indemnified  party in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
the  Underwriters  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.  The
relative  benefits  received by the Company on the one hand and the Underwriters
on the  other  shall be  deemed  to be in the same  proportion  as the total net
proceeds from the offering (before deducting  expenses)  received by the Company
bear  to the  total  underwriting  discounts  and  commissions  received  by the
Underwriters,  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, 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 the 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 contributions  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 Shares  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 1933 Act) shall be
entitled to  contribution  from any person who was not guilty of such fraudulent
misrepresentation.  The  Underwriters'  obligations  in this  subsection  (d) to
contribute   are  several  in  proportion  to  their   respective   underwriting
obligations 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 1933 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 1933 Act.

     9. (a) If any  Underwriter  shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery,  you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any  Underwriter  you do not arrange for the purchase of such Shares,
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 you to
purchase  such Shares on such terms.  In the event that,  within the  respective
prescribed  periods,  you notify the Company  that you have so arranged  for the
purchase of such Shares, or the Company notifies you that it has so arranged for
the purchase of such Shares, you or the Company shall have the right to postpone
such Time of  Delivery  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, or in any other documents or arrangements,  and the
Company agrees to file promptly any amendments to the Registration  Statement or
the  Prospectus  which in your opinion may thereby be made  necessary.  The term
"Underwriter"  as used in this  Agreement  shall include any person  substituted
under this  Section  with like  effect as if such person had  originally  been a
party to this Agreement with respect to such Shares.

     (b) If, after  giving  effect to any  arrangements  for the purchase of the
Shares of a defaulting  Underwriter  or  Underwriters  by you and the Company as
provided in  subsection  (a) above,  the  aggregate  number of such Shares which
remains  unpurchased does not exceed one-eleventh of the aggregate number of all
the Shares to be purchased at such Time of Delivery, then the Company shall have
the right to require each  non-defaulting  Underwriter to purchase the number of
shares  which such  Underwriter  agreed to  purchase  hereunder  at such Time of
Delivery  and,  in  addition,  to require  each  non-defaulting  Underwriter  to
purchase  its  pro  rata  share  (based  on the  number  of  Shares  which  such
Underwriter  agreed to  purchase  hereunder)  of the  Shares 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
Shares of a defaulting  Underwriter  or  Underwriters  by you and the Company as
provided in  subsection  (a) above,  the  aggregate  number of such Shares which
remains  unpurchased  exceeds  one-eleventh  of the aggregate  number of all the
Shares to be  purchased at such Time of  Delivery,  or if the Company  shall not
exercise the right  described in subsection (b) above to require  non-defaulting
Underwriters  to purchase  Shares of a defaulting  Underwriter or  Underwriters,
then this  Agreement  (or,  with  respect to the Second  Time of  Delivery,  the
obligations  of the  Underwriters  to  purchase  and of the  Company to sell the
Optional Shares) 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 Shares.

     11. If this Agreement shall be terminated pursuant to Section 9 hereof, the
Company  shall  not then be under any  liability  to any  Underwriter  except as
provided in Sections 6 and 8 hereof;  but, if for any other  reason,  any Shares
are not delivered by or on behalf of the Company as provided herein, the Company
will  reimburse  the  Underwriters  through you for all  out-of-pocket  expenses
approved  in  writing  by you,  including  fees and  disbursements  of  counsel,
reasonably incurred by the Underwriters in making preparations for the purchase,
sale and delivery of the Shares not so delivered,  but the Company shall then be
under no further  liability to any Underwriter  except as provided in Sections 6
and 8 hereof.

     12.  In all  dealings  hereunder,  you  shall  act on behalf of each of the
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 you as the representatives.

     All  statements,  requests,  notices and agreements  hereunder  shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co.,  85 Broad  Street,  New  York,  New  York  10004,  Attention:  Registration
Department;  and if to the  Company  shall be  delivered  or sent by mail 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 mail,  telex or  facsimile
transmission to such  Underwriter at its address set forth in its  Underwriters'
Questionnaire,  or telex constituting such Questionnaire,  which address will be
supplied  to the Company by you upon  request.  Any such  statements,  requests,
notices or agreements shall take effect upon receipt thereof.

     13. This  Agreement  shall be binding upon, and inure solely to the benefit
of, the Underwriters,  the Company and, to the extent provided in Sections 8 and
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.  No purchaser of any of the
Shares  from any  Underwriter  shall be deemed a  successor  or assign by reason
merely of such purchase.

     14. Time shall be of the essence of this  Agreement.  As used  herein,  the
term  "business  day"  shall  mean  any day  when  the  Commission's  office  in
Washington, D.C. is open for business.

     15. This  Agreement  shall be governed by and construed in accordance  with
the laws of the State of New York.

     16. This Agreement may be executed by any one or more of the parties hereto
in any number of counterparts,  each of which shall be deemed to be an original,
but all such counterparts shall together constitute one and the same instrument.

     17. The Company is authorized,  subject to applicable  law, to disclose any
and all aspects of this potential  transaction that are necessary to support any
U.S.  federal  income tax  benefits  expected to be claimed with respect to such
transaction, and all materials of any kind (including tax opinions and other tax
analyses)  related to those  benefits,  without the  Underwriters  imposing  any
limitation of any kind.

     If the foregoing is in accordance with your understanding,  please sign and
return to us  counterparts  hereof,  and upon the  acceptance  hereof by you, on
behalf of each of the Underwriters, this letter and such acceptance hereof shall
constitute a binding agreement between each of the Underwriters and the Company.
It is  understood  that your  acceptance of this letter on behalf of each of the
Underwriters is pursuant to the authority set forth in a form of Agreement among
Underwriters,  the  form  of  which  shall  be  submitted  to  the  Company  for
examination upon request,  but without warranty on your part as to the authority
of the signers thereof.

                                           Very truly yours,

                                           Vectren Corporation

                      FORM OF OPINION OF COMPANY'S COUNSEL
                           TO BE DELIVERED PURSUANT TO
                                  SECTION 7(c)



Based upon the foregoing and subject to the exceptions hereinafter set forth, we
are of the opinion that:

     (i) The Company  has been duly  incorporated  and is validly  existing as a
corporation under the laws of the State of Indiana.

     (ii) The  Company  has  corporate  power and  authority  to own,  lease and
operate  its  properties  and  to  conduct  its  business  as  described  in the
Prospectus and to execute,  deliver and perform the Agreement and consummate the
transactions contemplated under the Agreement.

     (iii) The Company is duly  qualified as a foreign  corporation  to transact
business  and  is  in  good  standing  in  each   jurisdiction   in  which  such
qualification  is  required,  whether by reason of the  ownership  or leasing of
property or the conduct of  business,  except where the failure so to qualify or
to be in good standing would not result in a Material Adverse Effect.

     (iv) The authorized,  issued and outstanding shares of capital stock of the
Company are as set forth in the Prospectus in the column entitled "Actual" under
the caption  "Capitalization"  (except for subsequent issuances thereof, if any,
pursuant to the  Agreement or pursuant to the exercise of options or pursuant to
various employee and director compensation plans, the dividend reinvestment plan
or  401(k)  plan  referred  to in the  Prospectus);  and all of the  issued  and
outstanding shares of capital stock of the Company have been duly authorized and
validly issued by the Company and are fully paid and  non-assessable and none of
such shares were issued in violation of the  preemptive or other similar  rights
of any securityholder of the Company.

     (v) The Shares have been duly  authorized  by the Company for  issuance and
sale  to the  Underwriters  pursuant  to the  Agreement  and,  when  issued  and
delivered  by the  Company  pursuant  to the  Agreement  against  payment of the
consideration set forth in the Agreement,  will be validly issued and fully paid
and  non-assessable;  no holder of the Shares is or will be subject to  personal
liability  by reason of being such a holder;  the  issuance of the Shares is not
subject to  preemptive  or other  similar  rights of any  securityholder  of the
Company; and the Common Stock, including the Shares, conforms to the description
thereof contain in the Prospectus.

     (vi) The Shareholders  Rights Agreement has been duly authorized,  executed
and  delivered  by the  Company  and  constitutes  a valid and  legally  binding
agreement of the Company, enforceable against the Company in accordance with its
terms, subject, as to enforceability, to bankruptcy, insolvency,  reorganization
and other laws of general  applicability  relating  to or  affecting  creditors'
rights and to general equity principles; the rights under the Shareholder Rights
Agreement  to which  holders  of the  Shares  will be  entitled  have  been duly
authorized  and validly  issued by the  Company;  and the Rights  conform to the
description thereof contained in the Prospectus.

     (vii) Each Significant Subsidiary has been duly incorporated and is validly
existing as a corporation, and where applicable, in good standing under the laws
of the jurisdiction of its  incorporation,  has corporate power and authority to
own,  lease and operate its  properties and to conduct its business as described
in the  Prospectus  and is duly  qualified as a foreign  corporation to transact
business  and  is  in  good  standing  in  each   jurisdiction   in  which  such
qualification  is  required,  whether by reason of the  ownership  or leasing of
property or the conduct of  business,  except where the failure so to qualify or
to be in good standing would not result in a Material Adverse Effect; all of the
issued and outstanding  shares of capital stock of each  Significant  Subsidiary
have been duly authorized and validly issued,  are fully paid and non-assessable
and, to the best of our knowledge, are owned by the Company, directly or through
subsidiaries,  free and clear of any security interest,  mortgage, pledge, lien,
encumbrance,  claim or equity  except  for  2,277  shares  of  non-voting  8.50%
redeemable  preferred stock of Southern  Indiana Gas and Electric  Company;  and
none of the outstanding  shares of capital stock of any  Significant  Subsidiary
were  issued  in  violation  of  the   preemptive  or  similar   rights  of  any
securityholder of such Significant Subsidiary.

     (viii) The  Agreement has been duly  authorized,  executed and delivered by
the Company.

     (ix) The Registration  Statement has been declared effective under the 1933
Act; any required filing of the Prospectus pursuant to Rule 424(b) has been made
in the manner and within the time period  required by Rule  424(b);  and, to the
best of our  knowledge,  no  stop  order  suspending  the  effectiveness  of the
Registration Statement has been issued under the 1933 Act and no proceedings for
that  purpose  have  been  instituted  or  are  pending  or  threatened  by  the
Commission.

     (x) The Registration Statement and the Prospectus,  excluding the documents
incorporated  by  reference  therein,  and each  amendment  to the  Registration
Statement and amendment or supplement to the Prospectus,  as of their respective
effective or issue dates (other than financial  statements and related notes and
schedules and financial data included therein or omitted therefrom,  as to which
we express no opinion),  complied as to form in all material  respects  with the
requirements of the 1933 Act and the 1933 Act Regulations.

     (xi) The documents  incorporated by reference in the Prospectus (other than
the financial  statements  (including  statistical  information included in such
financial  statements)  and  related  notes and  schedules  and  financial  data
included therein or omitted therefrom,  as to which we express no opinion), when
they  were  filed  with  the  Commission,  complied  as to form in all  material
respects with the requirements of the 1934 Act and the 1934 Act Regulations; and
we have no reason to believe  that any of such  documents,  when such  documents
were so filed,  contained an untrue  statement of a material  fact or omitted to
state a material fact necessary in order to make the statements  therein, in the
light of the  circumstances  under which they were made when such documents were
so filed, not misleading.

     (xii) The form of certificate  used to evidence the Shares  complies in all
material  respects  with  all  applicable  statutory   requirements,   with  any
applicable  requirements  of the charter and by-laws of the Company and with the
requirements of the Exchange.

     (xiii) To the best of our knowledge,  except as otherwise  disclosed in the
Registration  Statement and  Prospectus,  there is not pending or threatened any
action, suit, proceeding, inquiry or investigation,  to which the Company or any
of its subsidiaries is a party, or to which the assets, properties or operations
of the Company or any of its  subsidiaries is subject,  before or brought by any
court or governmental agency or body, domestic or foreign,  which may reasonably
be expected to result in a Material Adverse Effect, or which might reasonably be
expected to materially and adversely affect the assets, properties or operations
thereof,  or the consummation of the transactions  contemplated in the Agreement
or the performance by the Company of its obligations thereunder.

     (xiv) The information in the Prospectus under "Description of Stock" and in
the  Registration  Statement  under Item 15, to the extent  that it  constitutes
matters of law, summaries of legal matters, the Company's charter and by-laws or
legal proceedings, or legal conclusions,  has been reviewed by us and is correct
in all material respects.

     (xv) All descriptions in the  Registration  Statement and the Prospectus of
contracts  and other  documents to which the Company or any of its  subsidiaries
are a party are accurate in all material respects.

     (xvi) To the best of our  knowledge,  neither  the  Company  nor any of its
subsidiaries  is in  violation  of its  charter  or  by-laws.  Based  solely  on
inquiries we have made of the Company's Executive Vice President/Chief Financial
Officer,    Executive    Vice    President/General    Counsel/Secretary,    Vice
President/Treasurer  and  Vice   President/Controller,   and  on  the  officer's
certificate  attached  hereto as Schedule B, no default by the Company or any of
its subsidiaries  exists in the due performance or observance of any obligation,
agreement, covenant or condition contained in any contract, indenture, mortgage,
loan agreement,  note,  lease or other agreement or instrument that is described
or referred  to in the  Registration  Statement  or the  Prospectus  or filed or
incorporated by reference as an exhibit to the  Registration  Statement,  except
for defaults which  individually  or in the aggregate  would not have a Material
Adverse Effect.

     (xvii) The  execution,  delivery and  performance  of the Agreement and the
consummation  of  the  transactions  contemplated  in the  Agreement  and in the
Registration  Statement  (including  the issuance and sale of the Shares and the
use of the proceeds  from the sale of the Shares as described in the  Prospectus
under the caption  "Use Of  Proceeds")  and  compliance  by the Company with its
obligations under the Agreement do not and will not, whether with or without the
giving of notice or lapse of time or both,  conflict with or constitute a breach
of, or a default  or  Repayment  Event  under,  or  result  in the  creation  or
imposition of any lien,  charge or  encumbrance  upon any assets,  properties or
operations of the Company or any of its subsidiaries  pursuant to, any contract,
indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any
other  agreement or instrument,  known to us, to which the Company or any of its
subsidiaries  is a party or by which it or any of them may be bound, or to which
any of the  assets,  properties  or  operations  of  the  Company  or any of its
subsidiaries  is subject,  nor will such action  result in any  violation of the
provisions of the charter or by-laws of the Company or any of its  subsidiaries,
or any applicable law,  statute,  rule,  regulation,  judgment,  order,  writ or
decree,  known to us, of any government,  government  instrumentality  or court,
domestic  or  foreign,  having  jurisdiction  over  the  Company  or  any of its
subsidiaries or any of their respective assets, properties or operations.

     (xviii)  The  Company  is  not  an   "investment   company"  or  an  entity
"controlled"  by an "investment  company," as such terms are defined in the 1940
Act.

     (xix) No filing with, or authorization,  approval, consent, license, order,
registration, qualification or decree of, any court or governmental authority or
agency,  domestic  or  foreign  (other  than under the 1933 Act and the 1933 Act
Regulations,  which  have  been  obtained,  or as  may  be  required  under  the
securities  or blue sky laws of the  various  states,  as to which we express no
opinion) is  necessary  or required in  connection  with the due  authorization,
execution and delivery of the Agreement or for the offering, issuance or sale of
the Shares.

     Although we are not passing upon and do not assume any  responsibility  for
the accuracy and completeness of the statements (except as covered by (iv), (v),
(vi), (xiv) and (xv)) contained in the Registration Statement or Prospectus,  or
any  amendment  or  supplement  thereto,  we  advise  you,  on the  basis of the
discussions  and inquiries  concerning  various  legal and related  subjects and
reviews of and reports on certain corporate  records,  documents and proceedings
and conferences with representatives of the Company at which certain portions of
the  Registration  Statement and the Prospectus  were  discussed  (relying as to
materiality  to a certain  extent upon the opinions and  representations  of the
Company), no facts have come to our attention that would lead us to believe that
the  Registration  Statement or any amendment  thereto (other than the financial
statements  (including  statistical   information  included  in  such  financial
statements) and related notes and schedules and financial data included  therein
or  omitted  therefrom,  as to  which  we make no  comment),  at the  time  such
Registration  Statement or any such amendment became effective or at the date of
the  Agreement,  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 the  Prospectus or any amendment or
supplement thereto (other than the financial statements  (including  statistical
information  included  in such  financial  statements)  and  related  notes  and
schedules and financial data included therein or omitted therefrom,  as to which
we make no comment), at the time the Prospectus was issued, at the time any such
amendment or supplement  was issued or at the date hereof,  included or includes
an untrue  statement of a material  fact or omitted or omits to state a material
fact  necessary  in order to make the  statements  therein,  in the light of the
circumstances under which they were made, not misleading.

     In rendering such opinion, such counsel may rely as to matters of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates of

                           TO BE DELIVERED PURSUANT TO
                                  SECTION 7(c)

Based upon the foregoing and subject to the exceptions  hereinafter set forth, I
am of the opinion that:

     (i) The  information in the Company's  Amendment No. 1 to its annual report
on  Form  10-K/A  filed  June  18,  2003,  in Item 3 under  the  caption  "Legal
Proceedings",  and in the Prospectus,  to the extent that it constitutes matters
of law, summaries of legal matters or legal  proceedings,  or legal conclusions,
has been reviewed by me and is correct in all material respects.

     (ii) To the best of my knowledge,  neither the Company nor any  Significant
Subsidiary  is in  violation  of its  charter or  by-laws  and no default by the
Company or any of its  subsidiaries  exists in the due performance or observance
of any obligation,  agreement,  covenant or condition contained in any contract,
indenture,   mortgage,  loan  agreement,  note,  lease  or  other  agreement  or
instrument that is described or referred to in the Registration Statement or the
Prospectus  or  filed  or  incorporated  by  reference  as  an  exhibit  to  the
Registration  Statement,  except  for  defaults  which  individually  or in  the
aggregate would not have a Material Adverse Effect.

     (iii) To the best of my  knowledge,  there  are no  franchises,  contracts,
indentures,  mortgages,  loan  agreements,  notes,  leases or other  instruments
required to be  described  or referred to in the  Registration  Statement or the
Prospectus  or to be filed as exhibits  thereto  other than those  described  or
referred to therein or filed or incorporated  by reference as exhibits  thereto,
and the descriptions  thereof or references  thereto are correct in all material
respects.

     (iv) To the best of my knowledge, there are no statutes or regulations that
are  required  to be  described  in the  Prospectus  that are not  described  as
required.





     
                                                                      EXHIBIT B

                            [FORM OF COMFORT LETTER]

     Pursuant to Section 7(d) of the  Underwriting  Agreement,  the  accountants
shall furnish letters to the Underwriters to the effect that:

          (i) They are independent  certified public accountants with respect to
     the Company and its subsidiaries within the meaning of the 1933 Act and the
     1933 Act Regulations;

          (ii) In their opinion,  the financial statements and any supplementary
     financial   information  and  schedules  (and,  if  applicable,   financial
     forecasts  and/or pro forma  financial  information)  examined  by them and
     included or incorporated by reference in the Registration  Statement or the
     Prospectus  comply as to form in all material  respects with the applicable
     accounting requirements of the 1933 Act or the 1934 Act, as applicable, and
     the related published rules and regulations thereunder; and, if applicable,
     they have made a review in accordance  with  standards  established  by the
     American  Institute of Certified  Public  Accountants  of the  consolidated
     interim financial statements,  selected financial data, pro forma financial
     information,  financial  forecasts  and/or condensed  financial  statements
     derived from audited  financial  statements  of the Company for the periods
     specified in such letter, as indicated in their reports thereon,  copies of
     which have been furnished to the  representatives  of the Underwriters (the
     "Representatives");

          (iii)They have made a review in accordance with standards  established
     by the American  Institute of Certified Public Accountants of the unaudited
     condensed  consolidated  statements of income,  consolidated balance sheets
     and consolidated statements of cash flows included in the Prospectus and/or
     included in the Company's  quarterly  report on Form 10-Q  incorporated  by
     reference into the Prospectus as indicated in their reports  thereon copies
     of which have been separately furnished to the Representatives;  and on the
     basis of  specified  procedures,  including  inquiries  of officials of the
     Company who have  responsibility  for  financial  and  accounting  matters,
     regarding whether the unaudited condensed consolidated financial statements
     referred to in paragraph  (vi)(A)(i) below comply as to form in the related
     in all material respects with the applicable accounting requirements of the
     1933 Act and the 1934 Act and the related  published rules and regulations,
     nothing  came to their  attention  that  caused  them to  believe  that the
     unaudited condensed  consolidated  financial statements do not comply as to
     form in all material respects with the applicable  accounting  requirements
     of the  1933  Act and the  1934 Act and the  related  published  rules  and
     regulations;

          (iv) The unaudited selected financial  information with respect to the
     consolidated  results of operations  and financial  position of the Company
     for the five most  recent  fiscal  years  included  in the  Prospectus  and
     included or  incorporated  by reference in Item 6 of the  Company's  Annual
     Report  on Form  10-K for the  most  recent  fiscal  year  agrees  with the
     corresponding  amounts (after  restatement where applicable) in the audited
     consolidated  financial  statements  for such five fiscal  years which were
     included or  incorporated  by reference in the Company's  Annual Reports on
     Form 10-K for such fiscal years;

          (v)  They  have  compared  the  information  in the  Prospectus  under
     selected captions with the disclosure requirements of Regulation S-K and on
     the basis of limited  procedures  specified in such letter  nothing came to
     their attention as a result of the foregoing procedures that caused them to
     believe that this  information  does not conform in all  material  respects
     with  the  disclosure  requirements  of Items  301,  302,  402 and  503(d),
     respectively, of Regulation S-K;

          (vi)  On  the  basis  of  limited  procedures,   not  constituting  an
     examination  in accordance  with  generally  accepted  auditing  standards,
     consisting of a reading of the  unaudited  financial  statements  and other
     information  referred to below, a reading of the latest  available  interim
     financial statements of the Company and its subsidiaries, inspection of the
     minute  books of the  Company  and its  subsidiaries  since the date of the
     latest audited financial  statements  included or incorporated by reference
     in  the  Prospectus,   inquiries  of  officials  of  the  Company  and  its
     subsidiaries  responsible  for  financial and  accounting  matters and such
     other inquiries and procedures as may be specified in such letter,  nothing
     came to their attention that caused them to believe that:

               (A)  (i)  the  unaudited  condensed  consolidated  statements  of
          income,  consolidated  balance sheets and  consolidated  statements of
          cash flows included in the Prospectus  and/or included or incorporated

          of the 1934 Act and the 1934  Act  Regulations,  or (ii) any  material
          modifications  should be made to the unaudited condensed  consolidated
          statements of income,  consolidated  balance  sheets and  consolidated
          statements of cash flows included in the Prospectus or included in the
          Company's  Quarterly Reports on Form 10-Q incorporated by reference in
          the Prospectus,  for them to be in conformity with generally  accepted
          accounting principles;

               (B) any other unaudited  income  statement data and balance sheet
          items included in the  Prospectus do not agree with the  corresponding
          items in the unaudited  consolidated  financial  statements from which
          such data and items  were  derived,  and any such  unaudited  data and
          items were not determined on a basis substantially consistent with the
          basis  for  the  corresponding  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;

               (C) the unaudited financial statements which were not included in
          the  Prospectus  but from which were derived the  unaudited  condensed
          financial  statements  referred  to in  clause  (A) and any  unaudited
          income  statement  data  and  balance  sheet  items  included  in  the
          Prospectus  and  referred  to in clause (B) were not  determined  on a
          basis  substantially   consistent  with  the  basis  for  the  audited
          financial  statements  included or  incorporated  by  reference in the
          Company's Annual Report on Form 10-K for the most recent fiscal year;

               (D) any  unaudited  pro forma  consolidated  condensed  financial
          statements  included or incorporated by reference in the Prospectus do
          not comply as to form in all  material  respects  with the  applicable
          accounting  requirements  of the 1933 Act and the 1933 Act Regulations
          or the pro forma  adjustments  have not been  properly  applied to the
          historical amounts in the compilation of those statements;

               (E) as of a  specified  date not more than five days prior to the
          date of such letter,  there have been any changes in the  consolidated
          capital  stock (other than  issuances of capital  stock under  various
          employee and director  compensation  plans, the dividend  reinvestment
          plan  or  401((k)   plan  or  upon   exercise  of  options  and  stock
          appreciation  rights,  upon earn-outs of  performance  shares and upon

          outstanding  on the  date of the  latest  balance  sheet  included  or
          incorporated  by reference in the  Prospectus)  or any increase in the
          consolidated  long-term debt of the Company and its  subsidiaries,  or
          any  decreases in  consolidated  net current  assets or  stockholders'
          equity  or  other  items  specified  by  the  Representatives,  or any
          increases in any items specified by the Representatives,  in each case
          as compared with amounts shown in the latest balance sheet included or
          incorporated by reference in the  Prospectus,  except in each case for
          changes,  increases or decreases  which the Prospectus  discloses have
          occurred or may occur or which are described in such letter; and

               (F)  for  the  period  from  the  date  of the  latest  financial
          statements  included or incorporated by reference in the Prospectus to
          the specified  date referred to in clause (E) there were any decreases
          in consolidated  net revenues or operating  profit or the total or per
          share amounts of  consolidated  net income or other items specified by
          the  Representatives,  or any increases in any items  specified by the

          increases or decreases which the Prospectus discloses have occurred or
          may occur or which are described in such letter; and

          (vii)In  addition to the  examination  referred to in their  report(s)
     included or  incorporated  by reference in the  Prospectus  and the limited
     procedures,  inspection  of minute books,  inquiries  and other  procedures
     referred  to in  paragraphs  (iii) and (vi)  above,  they have  carried out
     certain specified procedures, not constituting an examination in accordance
     with  generally  accepted  auditing  standards,  with  respect  to  certain
     amounts,   percentages   and   financial   information   specified  by  the
     Representatives  which are derived from the general  accounting  records of
     the Company and its subsidiaries, which appear in the Prospectus (excluding
     documents  incorporated  by reference) or in Part II of, or in exhibits and
     schedules to, the Registration  Statement  specified by the Representatives
     or in documents  incorporated  by reference in the Prospectus  specified by

     its subsidiaries and have found them to be in agreement.
