                           Guarantees of Senior Notes

                             ----------------------

     o    Our  Senior  Notes due 2031,  which we refer to as the  "Notes",  bear
          interest  at the rate of _____%  per year.  The Notes  will  mature on
          October 15, 2031. However, we can redeem the Notes at our option on or
          after  October  19,  2006 at 100% of the  principal  amount  plus  any
          accrued interest thereon.

     o    Interest on the Notes is payable  quarterly  on January 15,  April 15,
          July 15, and  October  15,  beginning  on  January  15,  2002,  and at
          maturity or earlier redemption.

     o    The Notes will be jointly  and  severally  guaranteed  by Indiana  Gas
          Company,  Inc.,  Southern Indiana Gas and Electric Company and Vectren
          Energy  Delivery of Ohio,  Inc.  Each of these  companies  is a wholly
          owned  subsidiary of Vectren  Utility  Holdings,  Inc.  However,  each
          guarantee  is  subject to  termination  upon  satisfaction  of certain
          conditions.

     o    The Notes  will be  unsecured  and will rank  equally  with all of our
          other  unsecured  senior   indebtedness  and  junior  to  our  secured
          indebtedness, if any.

     o    With respect to each  guarantor,  the guarantee  will be unsecured and
          will rank equally with all of that guarantor's  other unsecured senior
          indebtedness, so long as the guarantee is in effect, and junior to its
          secured indebtedness.

     o    We will apply to list the Notes on the New York Stock  Exchange  under
          the symbol "_______." We expect trading of the Notes to begin within a
          30-day  period  after the initial  delivery of the Notes,  although we
          cannot  assure you that our listing  will be approved or trading  will
          begin at that time.

          You should  carefully  consider  the  factors  set forth  under  "Risk
Factors" beginning on page S-8 of this prospectus supplement.

                           FORWARD-LOOKING STATEMENTS

          Statements  contained or  incorporated by reference in this prospectus
supplement   regarding  future  events  and  developments  are  "forward-looking
statements"  within the  meaning of Section 27A of the  Securities  Act of 1933.
Forward-looking  statements  are  based  on  management's  beliefs  as  well  as
assumptions made by, and information currently available to, management. Because
such  statements  are based on  expectations  and not historical  facts,  actual
results may differ materially from those projected in the particular statements.
Important  factors  that  could  cause  future  results  to differ  include  the
following:

          o         Weather conditions;

          o         The  federal  and state  regulatory  environment,  including
                    changes  in   rate-setting   and   cost-recovery   policies,
                    environmental  regulations,  tax or  accounting  matters and
                    other laws and regulations to which we are subject;

          o         The economic climate, including inflation rates and monetary
                    policies;

          o         Unusual  or   unanticipated   changes  in  normal   business
                    operations, including unusual maintenance or repairs;

          o         Fluctuation  in supply,  demand,  transmission  capacity and
                    prices for energy commodities;

          o         Customer  growth within our service  territories and changes
                    in customers' usage patterns and energy preferences;

          o         Financial   market   conditions,    including   changes   in
                    availability of capital or interest rate fluctuations;

          o         Our  ability  to carry out our  marketing  and sales  plans,
                    along with the ability to realize synergies  associated with
                    our merger and investment strategies; and

          o         Employee workforce factors,  including changes in collective
                    bargaining unit agreements, strikes or work stoppages.

          These and other matters are difficult to predict,  and many are beyond
our  control,  including  those we discuss in this  prospectus  supplement,  the
accompanying  prospectus  and our  filings  with  the  Securities  and  Exchange
Commission.  Accordingly,  you should not rely on the  accuracy  of  predictions
contained in forward-looking  statements.  These statements speak only as of the
date of this prospectus supplement,  the accompanying prospectus or, in the case
of  documents  incorporated  by  reference,  the  dates of those  documents,  as
applicable.










                             SUMMARY OF THE OFFERING

          The  following   summary  is  not   complete.   For  a  more  detailed
description,  you should read all of the information  appearing elsewhere in, or
incorporated by reference in, this prospectus supplement and in the accompanying
prospectus.

             Vectren Utility Holdings, Inc. and Subsidiary Companies

          Vectren  Utility  Holdings,  Inc.  ("Utility  Holdings"),  an  Indiana
corporation,  is a wholly owned subsidiary of Vectren  Corporation  ("Vectren").
Utility  Holdings  was  formed  on March 31,  2000 to serve as the  intermediate
holding company for Vectren's operating public utilities:

          o         Indiana Gas Company, Inc. ("Indiana Gas"), formerly a wholly
                    owned subsidiary of Indiana Energy, Inc. ("Indiana Energy"),

          o         Southern Indiana Gas and Electric Company ("Southern Indiana
                    Gas"),  formerly a wholly owned subsidiary of SIGCORP,  Inc.
                    ("SIGCORP"), and

          o         the Ohio operations as described below.

          Utility  Holdings's  regulated  subsidiary  companies  currently serve
approximately  one  million  customers.  Indiana  Gas  provides  natural gas and
transportation services to a diversified base of customers in 311 communities in
49  of  Indiana's  92  counties.   Southern  Indiana  Gas  provides  generation,
transmission, distribution and the sale of electric power to Evansville, Indiana
and 74  other  communities  in 8  counties  in  southwestern  Indiana,  and  the
distribution  and sale of natural gas to Evansville,  Indiana and 64 communities
in 10 counties in southwestern  Indiana. The Ohio operations provide natural gas
distribution,  transportation  and sale of natural  gas to  Dayton,  Ohio and 16
counties in west central Ohio.

          On October 31, 2000,  Vectren  acquired  the natural gas  distribution
assets of The Dayton  Power and Light  Company  ("Dayton  Power") for a purchase
price  of  approximately  $465  million.   The  acquisition  added  310,000  gas
distribution customers in 16 counties in west central Ohio. Vectren acquired the
natural gas distribution  assets as a tenancy in common through two wholly owned
subsidiary companies.  Vectren Energy Delivery of Ohio, Inc. ("Vectren of Ohio")
holds a 53 percent undivided  ownership  interest in the assets, and Indiana Gas
holds a 47 percent undivided  ownership interest in the assets.  Vectren of Ohio
operates the natural gas distribution  assets, and these operations are referred
to in this  prospectus  supplement as "the Ohio  operations."  Utility  Holdings
established a $435 million  commercial paper program to fund the majority of the
acquisition;  this facility was fully  utilized at October 31, 2000.  Vectren of
Ohio's  portion  of  the  acquisition  was  initially   funded  with  short-term
borrowings from Utility  Holdings.  Indiana Gas's portion of the acquisition was
initially  funded with a  combination  of  short-term  borrowings  from  Utility
Holdings's  and Indiana  Gas's  commercial  paper  programs.  In February  2001,
Utility  Holdings repaid $129.4 million of commercial paper with proceeds from a
public  offering of Vectren's  common stock.  Over time, it is anticipated  that
permanent financing will fully replace these short-term borrowings.

          Vectren is an Indiana corporation that was organized on June 10, 1999,
solely for the purpose of effecting the merger of Indiana Energy and SIGCORP. On
March 31, 2000,  the merger of Indiana  Energy with SIGCORP and into Vectren was
consummated  with a tax-free  exchange of shares and has been accounted for as a
pooling of interests. The reorganization of Indiana Gas and Southern Indiana Gas
into  subsidiary  companies  of Utility  Holdings  has been  accounted  for as a
combination of entities under common control.  These transactions did not affect
the preferred stock and debt securities of Indiana Gas and Southern Indiana Gas.

          Utility Holdings's  principal executive offices are located at 20 N.W.
Fourth  Street,  Evansville,  Indiana  47711 and our  telephone  number is (812)
491-4000.

Optional Redemption
by Utility Holdings ................    We will have the  option  to redeem  the
                                        Notes, in whole or in part, from time to

                                        the redemption date.


Ranking.............................    The  Notes  will be  unsecured  and will
                                        rank  equally  with  all  of  the  other
                                        unsecured senior indebtedness of Utility
                                        Holdings.  The Notes will rank junior to
                                        the  secured   indebtedness  of  Utility
                                        Holdings,  if any.  Since  the Notes are
                                        guaranteed by our subsidiary  companies,
                                        the  Notes  will rank  equally  with the
                                        unsecured  senior  indebtedness  of  our
                                        subsidiary companies and junior to their
                                        secured indebtedness.  At June 30, 2001,
                                        Utility      Holdings      had     total
                                        unconsolidated   liabilities  of  $351.5
                                        million,  none of which was secured; our
                                        subsidiary     companies    had    total
                                        liabilities  of $1.4  billion,  of which
                                        $245.8  million  was  secured and $271.7
                                        million     represented     intercompany
                                        payables owing to Utility Holdings;  and
                                        Utility  Holdings  and its  subsidiaries
                                        had total  consolidated  liabilities  of
                                        $1.5 billion.

Guarantees..........................    Our operating public utility  subsidiary
                                        companies, Indiana Gas, Southern Indiana
                                        Gas and  Vectren of Ohio,  will  jointly
                                        and  severally  guarantee the payment of
                                        all of our obligations  under the Notes.
                                        With  respect  to  each  guarantor,  the
                                        guarantee  will be  unsecured  and  will
                                        rank    equally   with   all   of   that
                                        guarantor's   other   unsecured   senior
                                        indebtedness,  so long as that guarantee
                                        is in  effect,  and will rank  junior to
                                        its secured indebtedness.  Under certain
                                        circumstances,  the  guarantees  may  be
                                        terminated.

Ratings.............................    We  anticipate  that the  Notes  will be
                                        rated "A-" by Standard & Poor's  Ratings
                                        Services,  a division of The McGraw-Hill
                                        Companies,  Inc.,  and  "A2" by  Moody's
                                        Investors Service, Inc.

Use of Proceeds.....................    We  estimate  that we will  receive  net
                                        proceeds  from the sale of the  Notes of
                                        approximately  $____________.  We intend
                                        to use the proceeds from the offering of
                                        the  Notes  to  repay a  portion  of the
                                        commercial  paper we  issued to fund the
                                        acquisition of the Ohio operations.

Ratios of Earnings to Fixed
Charges.............................    Our  historical  ratios of  earnings  to
                                        fixed  charges  for  the  twelve  months
                                        ended on June  30,  2001 and each of the
                                        fiscal  years ended  December  31, 2000,
                                        1999,  1998,  1997 and 1996  were  2.3x,
                                        2.8x,   4.0x,   3.8x,   3.3x  and  4.1x,
                                        respectively.  The ratio for the  twelve
                                        months  ended on June 30, 2001  includes
                                        eight months of the Ohio operations, and
                                        the  ratio for the year  ended  December
                                        31, 2000 includes two months of the Ohio
                                        operations. The ratio for 1997 excluding
                                        restructuring  costs  of  $39.5  million
                                        would  have  been  3.6x.  The  ratio for
                                        fiscal  2000  excluding   merger-related
                                        costs of $44.1  million  would have been
                                        3.2x.  The ratio for the  twelve  months
                                        ended    June   30,    2001    excluding
                                        merger-related  costs of  $17.9  million
                                        and  restructuring-related   charges  of
                                        $10.8 million would have been 2.4x.






                                  RISK FACTORS

          You should  carefully  consider the risk factors  described  below, as
well  as  other  information  included  or  incorporated  by  reference  in this
prospectus   supplement  and  the  accompanying   prospectus  before  making  an
investment  in the Notes.  Additionally  risks and  uncertainties  not presently
known or that we currently  believe to be immaterial may also  adversely  affect
us.

The  Notes  will rank  junior to the  claims of  secured  creditors  of  Utility
Holdings and its subsidiary companies. Because of our holding company structure,
except  during  the  time  that  the  Notes  are  guaranteed  by our  subsidiary
companies,  the Notes will also rank junior to the claims of unsecured creditors
of our subsidiary companies.

          The Notes  will  rank  junior to all of the  secured  indebtedness  of
Utility  Holdings and its  subsidiary  companies to the extent of the underlying
collateral.  In  addition,  because we are a holding  company  and  conduct  our
operations through our subsidiary companies, our ability to meet our obligations
under our  indebtedness,  including  payment of principal of and any interest on
the Notes,  depends on the earnings and cash flows of our  subsidiary  companies
and the ability of our subsidiary companies to pay dividends or advance or repay
funds to us. Any right of ours or the holders of the Notes to participate in the
assets of any of our subsidiary  companies upon any liquidation,  dissolution or
reorganization  of any such  subsidiary  company  will be  subject  to the prior
claims of that subsidiary  company's secured creditors and, except to the extent
that a  guarantee  in respect of the Notes  from that  subsidiary  company is in
effect,  its  unsecured  creditors,  including  its  trade  creditors  and other
creditors who have obtained guarantees from that subsidiary  company,  unless we
are  recognized as a creditor of that  subsidiary  company on account of our own
claims.  Accordingly,  absent the  existence of guarantees  from our  subsidiary
companies,  the Notes will rank junior to the claims of  unsecured  creditors of
our subsidiary companies.  On the date of this prospectus supplement,  the Notes
are  guaranteed  by  Indiana  Gas,  Southern  Indiana  Gas and  Vectren of Ohio.
However, these guarantees may be terminated upon the disposition of a guarantor,
but only if certain  conditions are satisfied.  See  "Description of the Notes -
The Guarantees."

          At  June  30,  2001,   Utility   Holdings  had  total   unconsolidated
liabilities  of  $351.5  million,  none of which  was  secured;  our  subsidiary
companies had total  liabilities  of $1.4 billion,  of which $245.8  million was
secured and $271.7 million  represented  intercompany  payables owing to Utility
Holdings;  and Utility  Holdings  and its  subsidiaries  had total  consolidated
liabilities of $1.5 billion.

A court may be able to void any  guarantees of the Notes and require  holders of
the Notes to return payments received from the subsidiary guarantors.

          Under the federal  bankruptcy law and  comparable  provisions of state
fraudulent  transfer  laws,  a  guarantee  of the  Notes  by one or  more of our
subsidiary guarantors could be voided, or claims in respect of a guarantee could
be subordinated to all other debts of any subsidiary guarantor,  if, among other
things, that subsidiary guarantor, at the time it issued the guarantee:

          o         issued the guarantee to delay,  hinder or defraud present or
                    future creditors; or

          o         received  less  than  reasonably  equivalent  value  or fair
                    consideration for issuing the guarantee;

and at the time that subsidiary guarantor issued the guarantee, it

          o         was insolvent or rendered insolvent by reason of issuing the
                    guarantee or would be rendered insolvent upon payment of the
                    guarantee;

          o         was engaged or about to engage in a business or  transaction
                    for which that subsidiary guarantor's remaining unencumbered
                    assets  constituted  unreasonably  small capital to carry on
                    its business; or

          o         intended to incur,  or believed  that it would incur,  debts
                    beyond its ability to pay the debts as they mature.

          If a court determined that the issuance of a guarantee of the Notes by
a subsidiary  guarantor  violated  applicable federal and state law as described
above,  any payment by a subsidiary  guarantor  pursuant to its guarantee of the
Notes could be voided and required to be returned to that  subsidiary  guarantor
or a fund for the benefit of the creditors of that subsidiary guarantor,  or the
guarantee could be subordinated to other debts of that subsidiary guarantor.

          The measure of  insolvency  for purposes of  fraudulent  transfer laws
vary  depending  upon the law applied in any  proceeding to determine  whether a
fraudulent  transfer  has  occurred.  Generally,  however,  a  person  would  be
considered insolvent if, at the time it incurred the debt:

          o         the sum of its debts, including contingent liabilities, were
                    greater than the fair saleable value of all of its assets;

          o         the present fair saleable  value of its assets was less than
                    the  amount  that  would  be  required  to pay its  probable
                    liability  on  its  existing  debts,   including  contingent
                    liabilities, as they become absolute and mature; or

          o         it could not pay its debts as they become due.

          We  cannot  be  sure as to the  standard  that a  court  would  use to
determine  whether or not a  subsidiary  guarantor  was solvent at the  relevant
time, or,  regardless of the standard that the court uses,  that the issuance of
the  guarantee  of the Notes would not be voided or the  guarantee  of the Notes
would not be subordinated to that subsidiary guarantor's other debts.

          If  challenged,  any  guarantee  of  the  Notes  issued  by one of our
subsidiary  guarantors  could  also be subject to the claim  that,  because  the
guarantee  was issued for our benefit,  and only  indirectly  for the benefit of
that subsidiary  guarantor,  the  obligations of that subsidiary  guarantor were
incurred  for less than fair  consideration.  A court could  therefore  void the
obligations  under the guarantee or subordinate the guarantee to that subsidiary
guarantor's  other  debts or take other  actions  detrimental  to holders of the
Notes.







                                 USE OF PROCEEDS

          We estimate  that we will  receive net  proceeds  from the sale of the
Notes of approximately  $___________  after deducting the underwriting  discount
and commissions and estimated  offering expenses payable by us. We intend to use
the  proceeds  from the sale of the Notes to repay a portion  of our  commercial
paper  outstanding as of June 30, 2001,  which had a weighted  average  interest
rate of 2.57% per annum as of October 5, 2001 and had maturities  ranging from 4
days to 35 days.  We issued the  commercial  paper and other  short term debt to
fund the acquisition of the Ohio operations.

                       RATIOS OF EARNINGS TO FIXED CHARGES

     The following  table sets forth our ratios of earnings to fixed charges for
     the periods indicated.


                            Twelve Months
                                Ended          Fiscal Year Ended December 31,
                               June 30,        --------------------------------------------
                               2001 (1)        2000(2)       1999      1998     1997   1996
                            -------------      -------       ----      ----     ----   ----
                                                                     
                               2.3x             2.8x         4.0x      3.8x     3.3x   4.1x


----------------
          (1)       Includes eight months of the Ohio operations.
          (2)       Includes two months of the Ohio operations.

          For the purpose of computing  these  ratios,  earnings  consist of net
income plus income  taxes,  investment  tax  credits  and fixed  charges.  Fixed
charges  consist of total interest,  amortization of debt discount,  premium and
expense,  the  estimated  portion of interest  implicit in rentals and preferred
stock dividend of consolidated  subsidiary.  We  restructured  the operations of
Indiana  Gas in 1997 to  reduce  costs  and  remain  competitive.  The  ratio of
earnings to fixed charges for fiscal 1997  excluding the charge of $39.5 million
relating  to the  restructuring  would have been 3.6x.  The ratio of earnings to
fixed charges for fiscal 2000  excluding  merger-related  costs of $44.1 million
would have been 3.2x. In June 2001 we began implementing a restructuring plan to
eliminate administrative and supervisory positions in our utility operations and
corporate  office.  The ratio of earnings to fixed charges for the twelve months
ended  June  30,  2001  excluding  merger-related  costs of  $17.9  million  and
restructuring-related charges of $10.8 million would have been 2.4x.


                            DESCRIPTION OF THE NOTES

          Set forth below is a description  of the specific  terms of the Notes.
This  description  is not  complete,  and you should read it  together  with the
description of the general terms and provisions of the debt securities set forth
in the  accompanying  prospectus  under  the  caption  "Description  of the Debt
Securities." In addition, you should read all of the provisions of the indenture
(as amended or supplemented from time to time, the  "Indenture"),  to be entered
into  between us,  Indiana  Gas,  Southern  Indiana Gas and Vectren of Ohio,  as
guarantors,  and U.S.  Bank Trust  National  Association,  as trustee (the "Note
Trustee").

General

          The Notes will be issued as a separate series of debt securities under
the  Indenture.  The Notes  will be  limited in  aggregate  principal  amount to
$100,000,000,  subject to the reopening  provisions of the Indenture.  The Notes
will be issued in minimum  denominations  of $25 and integral  multiples of $25.
The  entire  principal  amount  of the  Notes,  unless  previously  redeemed  as
described below under  "--Optional  Redemption,"  will mature and become due and
payable, together with any unpaid interest accrued thereon, on October 15, 2031.
The Notes are not subject  to, or  entitled to the benefit of, any sinking  fund
provision.

Maturity

          In the event that any interest  payment date, the stated maturity date
or any redemption date is not a Business Day (as defined below), then payment of
principal of the Notes or any  interest on the Notes,  or both,  as  applicable,
will be made on the next Business Day (and without any interest or other payment
in respect of any such delay),  except that if such  Business Day is in the next
calendar year, the payment will be made on the  immediately  preceding  Business
Day,  in each case with the same  force  and  effect as if made on the  original
date. "Business Day" means any day other than a Saturday, Sunday or other day on
which  commercial  banks  are  authorized  or  required  by law,  regulation  or
executive order to close in The City of New York.

Ranking

          The Notes  will be  unsecured  and will rank  equally  with all of the
other unsecured  senior  indebtedness of Utility  Holdings.  The Notes will rank
junior to the secured indebtedness of Utility Holdings,  if any. Since the Notes
are guaranteed by our subsidiary companies, the Notes will rank equally with the
unsecured  senior  indebtedness of our subsidiary  companies and junior to their
secured   indebtedness.   At  June  30,   2001,   Utility   Holdings  had  total
unconsolidated  liabilities of $351.5  million,  none of which was secured;  our
subsidiary  companies had total  liabilities  of $1.4  billion,  of which $245.8
million was secured and $271.7 million represented  intercompany  payables owing
to  Utility  Holdings;  and  Utility  Holdings  and its  subsidiaries  had total
consolidated liabilities of $1.5 billion. See "Risk Factors--The Notes will rank
junior to the claims of secured creditors of Utility Holdings and its subsidiary
companies. Because of our holding company structure, except during the time that
the Notes are guaranteed by our subsidiary  companies,  the Notes will also rank
junior to the claims of unsecured  creditors of our subsidiary  companies."  See
also "--The Guarantees" below for a discussion of the circumstances in which the
guarantees of our subsidiary guarantors may be terminated.


Interest

          Each  Note  will  bear  interest  at ____%  per year  from the date of
original  issuance,  payable  quarterly in arrears on January 15, April 15, July
15, and October 15 of each year,  beginning January 15, 2002 (each, an "Interest
Payment  Date") to the person in whose name the Note is  registered at the close
of business as of the first  calendar  day of the month in which the  applicable
Interest  Payment  Date  falls  and,  if  applicable,  at  maturity  or  earlier
redemption,  as the case may be. The amount of interest payable will be computed
on the basis of a 360-day year of twelve 30-day months.

Optional Redemption

          We will  have the  option to redeem  the  Notes,  in whole or in part,
without premium,  from time to time, on or after October 19, 2006, upon not less
than 30 nor more than 60 days' prior written notice, at a redemption price equal
to 100% of the principal  amount to be redeemed plus any unpaid interest accrued
to the redemption date.

          On and after the redemption  date, the Notes to be redeemed will cease
to bear interest,  unless we default in the payment of the redemption  price. In
the event of such default, the principal of the Notes to be redeemed will, until
paid,  continue  to bear  interest  at the rate  indicated  on the cover of this
prospectus supplement.

          Subject to the  foregoing and to applicable  law  (including,  without
limitation, United States federal securities laws), we or our affiliates may, at
any time and from time to time,  purchase  outstanding  Notes by tender,  in the
open market or by private agreement. However, we may not use any purchased Notes
as a credit against any redemption obligation.

The Guarantees

          Indiana Gas,  Southern  Indiana Gas and Vectren of Ohio will,  jointly
and severally,  fully and unconditionally guarantee the performance and punctual
payment when due, whether at stated maturity,  by acceleration or otherwise,  of
all of our  obligations  under  the Notes and the  provisions  of the  Indenture
relating  to the Notes.  If we default  in  payment of the  principal  of or any
interest  on  the  Notes,  the  guarantors,   jointly  and  severally,  will  be
unconditionally  obligated  to duly  and  punctually  make  such  payments.  The
liability of each guarantor will be independent of, and not in  consideration of
or contingent  upon, our liability or the liability of any other party under the
Notes or the Indenture.  Further,  Utility  Holdings may in its sole  discretion
elect to cause  each  subsequent  subsidiary  of Utility  Holdings  to fully and
unconditionally  guarantee  all of the  obligations  under the Notes;  provided,
however,  that Utility Holdings has agreed to cause any subsequent subsidiary of
Utility  Holdings  that  guarantees  other  obligations  of Utility  Holdings to
guarantee the obligations under the Notes.

          With respect to each  guarantor,  the guarantee  will be unsecured and
rank  equal in right of payment  with all of that  guarantor's  other  unsecured
senior  indebtedness,  so long as that guarantee is in effect, and junior to its
secured  indebtedness.  Except as otherwise  specified in the second  succeeding
paragraph,  the guarantees will remain in full force and effect until payment in
full of all of the guaranteed obligations.

          Each  guarantor's  obligations  will be limited to the maximum  amount
that (after giving effect to all other contingent and fixed  liabilities of such
guarantor  and any  collections  from,  or payments made by or on behalf of, any
other  guarantors)  will result in the  obligations of such guarantor  under the
guarantee not constituting a fraudulent  conveyance or fraudulent transfer under
applicable law. See "Risk Factors--A court may be able to void any guarantees of
the Notes and require holders of the Notes to return payments  received from the
subsidiary guarantors."

          Notwithstanding   the  restrictions  on  transfer   described  in  the
accompanying prospectus under"-- Merger, Consolidation or Sale of Assets," if we
transfer or cause the transfer of all or substantially all of the voting capital
stock or assets of any  subsidiary  guarantor to any person other than us or one
of the other subsidiary guarantors,  whether by merger,  consolidation,  sale or
other  transfer,  all of the  obligations  and  liabilities  of that  subsidiary
guarantor under its guarantee will terminate upon transfer so long as:

          1.        such  subsidiary  guarantor  has  fully  repaid  all  of its
                    indebtedness,  if  any,  to  us  and  the  other  subsidiary
                    guarantors,

          2.        Standard  &  Poor's  Ratings  Services,  a  division  of The
                    McGraw-Hill Companies,  Inc., and Moody's Investors Service,
                    Inc., or their  successors,  have each confirmed  that, as a
                    result of the transfer, our long term credit rating will not
                    fall below BBB- (or its equivalent), in the case of Standard
                    &  Poor's,  and  Baa3  (or its  equivalent),  in the case of
                    Moody's, and

          3.        immediately  before and  immediately  after giving effect to
                    the transfer,  no event of default and no event which, after
                    notice or passage of time or both,  would become an event of
                    default shall have occurred and be continuing.

Book-Entry Only Issuance - The Depository Trust Company

          DTC will act as the initial  securities  depositary for the Notes. The
Notes will be issued only as fully registered  securities registered in the name
of Cede & Co., DTC's  partnership  nominee.  One or more fully registered global
Notes will be issued,  representing in the aggregate the total principal  amount
of Notes, and will be deposited with DTC.

          DTC is a  limited-purpose  trust company  organized under the New York
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning  of the  New  York  Uniform  Commercial  Code  and a  "clearing  agency"
registered  pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934. DTC holds securities that its participants ("Direct  Participants")
deposit with DTC. DTC also facilitates the settlement among Direct  Participants
of  securities  transactions,  such  as  transfers  and  pledges,  in  deposited
securities  through  electronic   computerized   book-entry  changes  in  Direct
Participants'  accounts,  thereby  eliminating the need for physical movement of
securities  certificates.  Direct  Participants  include  securities brokers and
dealers,  banks,  trust  companies,  clearing  corporations  and  certain  other
organizations.  DTC is owned by a number of its Direct  Participants  and by the
New York Stock Exchange,  Inc., the American Stock Exchange LLC and the National
Association  of  Securities  Dealers,  Inc.  Access  to the DTC  system  is also
available  to others such as  securities  brokers and  dealers,  banks and trust
companies that clear through or maintain a custodial  relationship with a Direct
Participant, either directly or indirectly ("Indirect Participants").  The rules
applicable to DTC and its Direct  Participants  are on file with the  Securities
and Exchange Commission.

          Purchases  of Notes  under the DTC  system  must be made by or through
Direct Participants, which will receive a credit for the Notes on DTC's records.
The ownership interest of each actual purchaser of Notes ("Beneficial Owner") is
in turn  to be  recorded  on the  Direct  and  Indirect  Participants'  records.
Beneficial  Owners  will  not  receive  written  confirmation  from DTC of their
purchases,  but Beneficial Owners are expected to receive written  confirmations
providing details of the transactions,  as well as periodic  statements of their
holdings,  from the Direct or Indirect Participants through which the Beneficial
Owners entered into the  transactions.  Transfers of ownership  interests in the
Notes are to be accomplished by entries made on the books of Direct and Indirect
Participants  acting on behalf of Beneficial Owners.  Beneficial Owners will not
receive certificates  representing their ownership interests in Notes, except in
the event that use of the book-entry system for the Notes is discontinued and we
determine that Beneficial Owners may exchange their ownership interests for such
certificates or if an event of default under the Indenture occurs.

          To  facilitate  subsequent  transfers,  all Notes  deposited by Direct
Participants with DTC are registered in the name of DTC's  partnership  nominee,
Cede  &  Co.  or  such  other  name  as  may  be  requested  by  an   authorized
representative  of DTC. The deposit of Notes with DTC and their  registration in
the name of Cede & Co.  or such  other  nominee  do not  effect  any  change  in
beneficial  ownerships.  DTC will have no  knowledge  of the  actual  Beneficial
Owners of the Notes;  DTC's  records  reflect  only the  identity  of the Direct
Participants  to whose accounts the Notes are credited,  which may or may not be
the  Beneficial  Owners.  The  Direct  and  Indirect  Participants  will  remain
responsible for keeping account of their holdings on behalf of their customers.

          Conveyance  of  notices  and  other  communications  by DTC to  Direct
Participants,  by Direct  Participants  to Indirect  Participants  and by Direct
Participants and Indirect  Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory  requirements as
may be in effect from time to time.

          Redemption  notices will be sent to DTC. If less than all of the Notes
are  being  redeemed,  DTC's  practice  is to  reduce  by lot the  amount of the
interest of each Direct Participant in the Notes to be redeemed.

          Although  voting with respect to the Notes is limited,  in those cases
where a vote is  required,  neither DTC nor Cede & Co. will consent or vote with
respect  to the  Notes.  Under its usual  procedures,  DTC would mail an Omnibus
Proxy to us as soon as possible after the record date. The Omnibus Proxy assigns
Cede & Co.'s  consenting or voting rights to those Direct  Participants to whose
accounts  the Notes are  credited  on the record date  (identified  in a listing
attached to the Omnibus Proxy).

          Payments on the Notes will be made to Cede & Co. DTC's  practice is to
credit  Direct  Participants'   accounts,   upon  DTC's  receipt  of  funds  and
corresponding  detail  information  from us,  on the  relevant  payment  date in
accordance with their  respective  holdings shown on DTC's records.  Payments by
Participants to Beneficial Owners will be governed by standing  instructions and
customary  practices,  as is the case with  securities  held for the  account of
customers  in  bearer  form or  registered  in  "street  name,"  and will be the
responsibility   of  such  Participant  and  not  our   responsibility   or  the
responsibility  of DTC,  subject to any statutory or regulatory  requirements as
may be in  effect  from  time to  time.  Payment  to DTC is our  responsibility,
disbursements of such payments to Direct  Participants is the  responsibility of
DTC  and  disbursements  of  such  payments  to  the  Beneficial  Owners  is the
responsibility of Direct and Indirect Participants.

          Except as  provided  herein,  a  Beneficial  Owner of an interest in a
global  Note  will not be  entitled  to  receive  physical  delivery  of  Notes.
Accordingly,  each  Beneficial  Owner  must  rely  on the  procedures  of DTC to
exercise any rights under the Notes. The laws of some jurisdictions require that
certain  purchasers  of  securities  take  physical  delivery of  securities  in
definitive  form.  Such laws may  impair  the  ability  to  transfer  beneficial
interests in a global Note.

          DTC may discontinue providing its services as security depository with
respect to the Notes at any time by giving  reasonable  notice to us. Under such
circumstances,  in the  event  that a  successor  securities  depository  is not
obtained,  Note  certificates  will be printed and  delivered  to the holders of
record.

          Additionally,  we may  decide  to  discontinue  use of the  system  of
book-entry transfers through DTC (or a successor depository) with respect to the
Notes.  In that event,  or if there is an event of default under the  Indenture,
certificates  for the Notes  will be printed  and  delivered  to the  holders of
record.

          The  information in this section  concerning DTC and DTC's  book-entry
system has been  obtained  from sources  that we believe to be reliable,  but we
take  no  responsibility  for  the  accuracy  of the  information.  We  have  no
responsibility  for  the  performance  by  DTC  or  its  Participants  of  their
respective  obligations  as  described  in this  section  or under the rules and
procedures governing their respective operations.


                                     RATINGS

          It is  anticipated  that Standard & Poor's and Moody's will assign the
Notes the ratings set forth on the cover page of this prospectus supplement. The
ratings reflect only the views of the rating agencies, and an explanation of the
significance of the ratings may be obtained only from the rating agencies at the
following  addresses:  Standard & Poor's, 25 Broadway,  New York, New York 10004
and Moody's,  99 Church Street,  New York, New York 10007. There is no assurance
that the ratings  will,  in fact, be assigned or remain in effect for any period
of time or that they will not be revised  downward or withdrawn  entirely by the
rating agencies if, in their judgment,  circumstances  warrant.  Neither Utility
Holdings nor the Underwriters  have undertaken any  responsibility to oppose any
proposed  downward revision or withdrawal of a rating on the Notes. Any downward
revision or withdrawal of the ratings would likely have an adverse effect on any
trading market for, and/or the market price of, the Notes.

          At present,  each of the rating agencies  maintains four categories of
investment  grade  ratings.  They are for Standard & Poor's - AAA, AA, A and BBB
and for Moody's - Aaa, Aa, A and Baa. You may obtain further  explanation of the
significance of these ratings from Standard & Poor's and Moody's.






                                  UNDERWRITING

          Subject to the terms and conditions of an underwriting  agreement,  we
have agreed to sell to the  Underwriters,  and the  Underwriters  severally have
agreed to  purchase  from us,  the entire  principal  amount of the Notes in the
respective principal amounts of the Notes set forth opposite their names below:

            Underwriter                            Principal Amount
            -----------                            ----------------

                                                   ================

          The Underwriters propose initially to offer the Notes to the public at
the  public  offering  price  set  forth on the  cover  page of this  prospectus
supplement  and to dealers at that price less a concession not in excess of ___%
of the  principal  amount of the Notes.  The  Underwriters  may allow,  and such
dealers may reallow,  a discount not in excess of ____% of the principal  amount
of the Notes to other  dealers.  After the initial public  offering,  the public
offering price, concession and discount may be changed.

          The Notes are a new issue of securities  with no  established  trading
market.  We will  apply to list the Notes on the New York  Stock  Exchange  (the
"NYSE").  We expect  trading  of the Notes on the NYSE to begin  within a 30-day
period after the initial  delivery of the Notes,  although we cannot  assure you
that our  listing  will be  approved  or trading  will  begin at that time.  The
Underwriters  have advised us that,  prior to the commencement of trading on the
NYSE, they intend to make a market in the Notes. The  Underwriters  will have no
obligation to make a market in the Notes,  however,  and may discontinue  market
making activities, if commenced, at any time without notice.

          We and our subsidiary  guarantors have jointly and severally agreed to
indemnify the Underwriters  against certain liabilities,  including  liabilities
under the Securities Act of 1933, or to contribute to payments the  Underwriters
may be required to make in respect of those liabilities.

          We have  agreed,  during  the period of 15 days from the date on which
the Notes are purchased by the  Underwriters,  not to sell, offer to sell, grant
any option for the sale of, or otherwise  dispose of any additional  Notes,  any
security  convertible into or exchangeable  into or exercisable for Notes or any
debt securities  substantially  similar to the Notes or any security convertible
into, exchangeable into or exercisable for any such debt securities, without the
prior written consent of the Underwriters.

          Some of the Underwriters and their affiliates have performed  services
for us and our affiliates in the past. They have received customary compensation
for these services.


                                 LEGAL OPINIONS

          The  validity  of the  Notes  will be  passed  upon for us by Barnes &
Thornburg,  Indianapolis,  Indiana.  Certain matters will be passed upon for the
Underwriters by Sidley Austin Brown & Wood LLP, New York, New York.

                           FORWARD-LOOKING STATEMENTS

     Statements  contained  or  incorporated  by  reference  in this  prospectus
regarding future events and developments are "forward-looking statements" within
the  meaning  of  Section  27A of the  Securities  Act of 1933.  Forward-looking
statements are based on management's beliefs as well as assumptions made by, and
information  currently  available to,  management.  Because such  statements are
based on  expectations  and not  historical  facts,  actual  results  may differ
materially from those projected in the particular statements.  Important factors
that could  cause  future  results to differ  include  any  listed  under  "Risk
Factors" in the related prospectus supplement and the following:

     o    Weather conditions;

     o    The federal and state  regulatory  environment,  including  changes in
          rate-setting and cost-recovery  policies,  environmental  regulations,
          tax or accounting  matters and other laws and  regulations to which we
          are subject;

     o    The economic climate, including inflation rates and monetary policies;

     o    Unusual  or  unanticipated  changes  in  normal  business  operations,
          including unusual maintenance or repairs;

     o    Fluctuation in supply,  demand,  transmission  capacity and prices for
          energy commodities;

     o    Customer  growth  within  our  service   territories  and  changes  in
          customers' usage patterns and energy preferences;

     o    Financial  market  conditions,  including  changes in  availability of
          capital or interest rate fluctuations;

     o    Our ability to carry out our marketing and sales plans, along with the
          ability to realize synergies associated with our merger and investment
          strategies; and

     o    Employee workforce factors, including changes in collective bargaining
          unit agreements, strikes or work stoppages.

These and other  matters  are  difficult  to  predict,  and many are  beyond our
control,  including those we discuss in this prospectus and our filings with the
Securities  and  Exchange  Commission.  Accordingly,  you should not rely on the
accuracy  of  predictions   contained  in  forward-looking   statements.   These
statements  speak  only as of the  date of this  prospectus  or,  in the case of
documents incorporated by reference, the dates of those documents.









             VECTREN UTILITY HOLDINGS, INC. AND SUBSIDIARY COMPANIES

     Vectren  Utility   Holdings,   Inc.   ("Utility   Holdings"),   an  Indiana
corporation,  is a wholly owned subsidiary of Vectren  Corporation  ("Vectren").
Utility  Holdings  was  formed  on March 31,  2000 to serve as the  intermediate
holding company for Vectren's operating public utilities:

     o    Indiana Gas Company,  Inc.  ("Indiana  Gas"),  formerly a wholly owned
          subsidiary of Indiana Energy, Inc. ("Indiana Energy"),

     o    Southern  Indiana Gas and Electric Company  ("Southern  Indiana Gas"),
          formerly a wholly owned subsidiary of SIGCORP, Inc. ("SIGCORP"), and

     o    the Ohio operations as described below.

     Utility Holdings'  regulated  subsidiary  companies serve approximately one
million customers.  Indiana Gas provides natural gas and transportation services
to a  diversified  base of  customers in 311  communities  in 49 of Indiana's 92
counties. Southern Indiana Gas provides generation,  transmission,  distribution
and the sale of electric power to Evansville, Indiana, and 74 other communities,
and the  distribution  and sale of natural gas to  Evansville,  Indiana,  and 64
communities in ten counties in southwestern Indiana. The Ohio operations provide
natural gas distribution, transportation and sale of natural gas to Dayton, Ohio
and 16 counties in west central Ohio.

     On October 31, 2000,  Vectren acquired the natural gas distribution  assets
of The Dayton Power and Light Company  ("Dayton  Power") for a purchase price of
approximately  $465 million.  The  acquisition  added  310,000 gas  distribution
customers in 16 counties in west central Ohio.  Vectren acquired the natural gas
distribution  assets as a tenancy in common through two wholly owned  subsidiary
companies.  Vectren Energy Delivery of Ohio, Inc. ("Vectren of Ohio") holds a 53
percent undivided  ownership  interest in the assets, and Indiana Gas holds a 47
percent undivided ownership interest in the assets. Vectren of Ohio operates the
natural  gas  distribution  assets;  the  operations  are  referred  to in  this
prospectus as "the Ohio operations." Utility Holdings established a $435 million
commercial paper program to fund the majority of the acquisition;  this facility
was fully utilized at October 31, 2000. In February 2001,  Vectren repaid $129.4
million of commercial  paper with proceeds from a public  offering of its common
stock.  Vectren of Ohio's portion of the  acquisition was funded with short-term
borrowings from Utility  Holdings.  Indiana Gas's portion of the acquisition was
funded with a combination of short-term  borrowings from Utility  Holdings's and
Indiana Gas's  commercial  paper  programs.  Over time, it is  anticipated  that
permanent financing will replace these short-term borrowings.

     Vectren is an Indiana  corporation  that was  organized  on June 10,  1999,
solely for the purpose of effecting the merger of Indiana Energy and SIGCORP. On
March 31, 2000,  the merger of Indiana  Energy with SIGCORP and into Vectren was
consummated  with a tax-free  exchange of shares and has been accounted for as a
pooling of interests. The reorganization of Indiana Gas and Southern Indiana Gas
into  subsidiary  companies  of Utility  Holdings  has been  accounted  for as a
combination of entities under common control.  These transactions did not affect
the preferred stock and debt securities of Indiana Gas and Southern Indiana Gas.

     Utility Holding's principal executive offices are located at 20 N.W. Fourth
Street, Evansville, Indiana 47711 and our telephone number is (812) 491-4000.

     If you want to find more  information  about us,  please  see the  sections
entitled "Where You Can Find More Information" and "Incorporation of Information
We File with the SEC" in this prospectus.

                                 USE OF PROCEEDS

     Unless otherwise specified in the applicable prospectus supplement, we will
use the net proceeds from the sale of the debt securities for general  corporate
purposes,  including  reducing  short-term  debt and  financing  the  continuing
construction program of the operating public utility subsidiary companies.

                       RATIOS OF EARNINGS TO FIXED CHARGES

     The following  table sets forth our historical  ratios of earnings to fixed
charges for the periods indicated. This information has been restated to reflect
the  reorganization  of Indiana Gas and  Southern  Indiana  Gas into  subsidiary
companies of Utility Holdings.


         Twelve Months
         Ended June 30,             Fiscal Year Ended December 31,
         --------------     ----------------------------------------------------
         2001(1)            2000(2)    1999       1998       1997        1996

          2.3x               2.8x      4.0x       3.8x       3.3x        4.1x

     (1)  Includes  eight  months  of the Ohio  operations  of the  natural  gas
          business of Dayton Power.

     (2)  Includes two months of the Ohio operations of the natural gas business
          of Dayton Power.

     For the purpose of computing these ratios,  earnings  consist of net income
plus income  taxes,  investment  tax credits and fixed  charges.  Fixed  charges
consist of total interest,  amortization of debt discount,  premium and expense,
the  estimated  portion of  interest  implicit in rentals  and  preferred  stock
dividend of consolidated  subsidiary.  We restructured the operations of Indiana
Gas in 1997 to reduce  costs and remain  competitive.  The ratio of  earnings to
fixed  charges  for fiscal  1997  excluding  the  restructuring  charge of $39.5
million  relating  to the  restructuring  would  have  been  3.6x.  The ratio of
earnings  to fixed  charges for fiscal 2000  excluding  merger-related  costs of
$44.1  million  would  have  been  3.2x.  In June 2001 we began  implementing  a
restructuring plan to eliminate  administrative and supervisory positions in our
utility  operations and corporate office. The ratio of earnings to fixed charges
for the twelve  months ended June 30, 2001  excluding  merger  related  costs of
$17.9 million and restructuring-related charges of $10.8 million would have been
2.4x.

                       DESCRIPTION OF THE DEBT SECURITIES
General

     We may issue debt  securities  from time to time in one or more series.  We
will issue the debt securities pursuant to an indenture between us and U.S. Bank
Trust National  Association,  as trustee.  Indiana Gas, Southern Indiana Gas and
Vectren of Ohio  (collectively,  the  "guarantors")  will jointly and  severally
guarantee the debt securities pursuant to a guarantee in favor of holders of the
debt  securities.  We have filed the forms of the indenture and the guarantee as
exhibits  to the  registration  statement  of which this  prospectus  is a part,
subject to such  amendments or  supplements as may be adopted from time to time.
The indenture,  as amended or supplemented  from time to time in accordance with
its  terms,  is  referred  to in this  prospectus  as the  "indenture,"  and the
guarantee,  as amended or supplemented  from time to time in accordance with its
terms, is referred to in this prospectus as the  "guarantee." The indenture will
be subject to and governed by the Trust  Indenture Act of 1939, as amended.  The
aggregate  principal  amount of debt  securities  which we may  issue  under the
indenture  will be unlimited and the indenture will set forth the specific terms
of any series of debt  securities  or provide  that such terms will be set forth
in, or determined pursuant to, a board resolution  authorizing the series and/or
a supplemental indenture, if any, relating to such series.

     We describe the debt securities,  the indenture and the guarantee below. We
do not claim the summaries are complete.  For a more detailed  description,  you
should read all of the provisions of the indenture and the guarantee. You should
also read the applicable  prospectus  supplement,  including any applicable U.S.
federal  income  tax  considerations  and  any  applicable  modifications  of or
additions to the general  terms  described  below in the  applicable  prospectus
supplement.

          any, on the debt securities will be payable;

     (12) if the  principal of or premium,  if any, or interest,  if any, on the
          debt securities is to be payable, at our election or the election of a

          securities  are stated to be  payable,  the  period or periods  within

     (13) if the amount of  payments  of  principal  of or  premium,  if any, or

          redeem the debt securities in lieu of making such payment;

     (15) any  provision  relating  to the  issuing  of the debt  securities  as
          original issue discount securities (including, without limitation, the

          original  issue  discount,  if any,  will accrue and the date or dates
          from or to which,  or period or periods  during  which,  the  original
          issue discount will accrue;

          securities; and

          securities which shall be issued and outstanding.

     Any  series  of  debt  securities  may  be  reopened  and  additional  debt
securities  of that  series may be issued  without the consent of the holders of
that series.

     If the applicable prospectus  supplement provides,  the debt securities may
be issued at a discount below their principal  amount and provide that less than
the  entire  principal  amount  of the  debt  securities  will be  payable  upon
declaration  of  acceleration  of the maturity of the debt  securities.  In such
cases, all material U.S. federal income tax considerations  will be described in
the applicable prospectus supplement.

     Except as may be set forth in the  applicable  prospectus  supplement,  the
debt  securities will not contain any provisions that would limit our ability to
incur indebtedness or that would afford holders of debt securities protection in
the event of a highly  leveraged  transaction  involving us or in the event of a
change of control.

Denomination, Interest, Registration and Transfer

     We will issue the debt  securities of each series only in registered  form,
without  coupons,  in  denominations  of $1,000,  or in such other currencies or
denominations  as may be set forth in the indenture or specified in, or pursuant
to, a board resolution  authorizing the series and/or a supplemental  indenture,
if any, relating to the series of debt securities.

     The principal of and premium,  if any, and interest,  if any, on any series
of debt securities will be payable at the corporate trust office of the trustee.
The  address  of  the  trustee  will  be  stated  in the  applicable  prospectus
supplement.

     Subject to  certain  limitations  imposed  upon debt  securities  issued in
book-entry form, the debt securities of any series:

     -    will be  exchangeable  for any authorized  denomination  of other debt
          securities of the same series and of a like aggregate principal amount
          and tenor  upon  surrender  of the debt  securities  at the  trustee's
          corporate trust office or at the office of any registrar designated by
          us for that purpose; and

     -    may be  surrendered  for  registration  of transfer or exchange at the
          corporate  trust  office  of  the  trustee  or at  the  office  of any
          registrar designated by us for that purpose.

     No  service  charge  will  be made  for any  registration  of  transfer  or
exchange,  but we may require  payment of a sum  sufficient  to cover any tax or
other  governmental  charge  payable in  connection  with certain  transfers and
exchanges.  We may act as registrar and may change any registrar  without notice
to the holders of any series of debt securities.

Certain Covenants

     The applicable  prospectus  supplement will describe any material covenants
in  respect  of a  series  of debt  securities  that are not  described  in this
prospectus.  Unless otherwise indicated in the applicable prospectus supplement,
the debt securities will include the covenants described below.

of interest implicit in the terms of the lease, of the obligations of the lessee
under such lease for net rental payments during the remaining term of the lease,
including  any  period for which such  lease has been  extended  or may,  at our

               companies'  consolidated  income  as of the end of any two of the
               three most recently completed fiscal years.

     "stated maturity" when used with respect to any security or any installment
of interest on the security will mean the date  specified in the security as the

interest is due and payable.

     Restrictions on liens

     We will not incur,  create,  assume or otherwise become liable with respect
to any  indebtedness  secured by a lien,  or guarantee any  indebtedness  with a
guarantee that is secured by a lien, on any principal  domestic  property or any
shares  of  stock  or  indebtedness  of  any  significant  subsidiary,   without
effectively providing that the debt securities of each series (together with, if
we so determine,  any other  indebtedness  then  existing or thereafter  created
ranking equally with the debt securities of each series) will be secured equally
and ratably  with (or, at our option,  prior to) such secured  indebtedness,  so
long as the secured  indebtedness will be so secured;  provided,  however,  that
this covenant will not apply to indebtedness secured by:

          (1)  liens existing on the date of the indenture;

          (2)  liens in favor of governmental bodies to secure progress, advance
               or other payments;

               incurred  prior to, at the time of, or within  360 days after the
               later  of  the  acquisition,  completion  of  such  construction,
               installation,  renovation,  improvement  or  development  or  the
               commencement  of full  operation  of such  property or within 360
               days after the acquisition of such shares or indebtedness for the

               thereof;

          (4)  liens securing  indebtedness in an aggregate amount which, at the
               time of incurrence and together with all outstanding attributable
               debt in respect of sale and leaseback  transactions  permitted by
               clause (2) in the "Restrictions on sales and leasebacks" covenant
               described  below,  does  not  exceed  10  percent  of our and our

          (5)  liens securing indebtedness other than funded debt; and

          (6)  any extension,  renewal or replacement (or successive extensions,
               renewals  or  replacements),  in whole  or in  part,  of any lien
               referred  to in the above  clauses  (1)  through  (5)  inclusive;
               provided that the  extension,  renewal or replacement of the lien
               is  limited  to all or any part of the same  property,  shares of
               stock or indebtedness that secured the lien extended,  renewed or
               replaced  (plus  improvements  on the  property),  and  that  the
               secured indebtedness at the time is not increased.

     Restrictions on sales and leasebacks

     We will not enter into any sale and leaseback transaction, unless:

          (1)  the principal  domestic property is sold within 360 days from the
               date of acquisition of the property or the date of the completion
               of  construction  or  commencement  of  full  operations  of  the
               property, whichever is later; or

          (2)  within 120 days after a sale  described  in clause (1) above,  we
               will apply or cause to be applied to the retirement of our funded
               debt or the funded debt of any of our subsidiary companies (other
               than  our  funded  debt  which by its  terms or the  terms of the
               instrument  pursuant  to which it was  issued is  subordinate  in
               right of payment to the debt securities of each series) an amount
               not less than the greater of (A) the net  proceeds of the sale of
               the  principal  domestic  property  or (B)  the  fair  value  (as
               determined  in any manner  approved by our board of directors) of
               the principal domestic property.

     The  provisions  of this  covenant  will not  prevent a sale and  leaseback
transaction if:

          (1)  the lease we entered into in connection  with the  transaction is
               for a period, including renewals, of not more than 36 months; or

          (2)  we would,  at the time of  entering  into the sale and  leaseback
               transaction,  be entitled,  without equally and ratably  securing
               the debt securities,  to create or assume a lien on the principal
               domestic  property  securing  indebtedness  in an amount at least
               equal  to the  attributable  debt  in  respect  of the  sale  and
               leaseback  transaction  pursuant  to  clause  (4)  above  in  the
               "Restrictions on liens" covenant.

Merger, Consolidation or Sale of Assets

     We and the  guarantors  each agree that neither we nor it will  consolidate
with or merge with or into any other person or transfer all or substantially all
of our or its  respective  properties  and assets as an  entirety to any person,
unless:

          (1)  either  we or the  guarantor,  as the  case  may be,  will be the
               continuing  person,  or  the  person  (if  other  than  us or the
               guarantor)  formed by the  consolidation  or into which we or the
               guarantor are merged or to which all or substantially  all of our
               properties  and  assets  or  the  properties  and  assets  of the
               guarantor  as  an  entirety  are  transferred  is  a  corporation
               organized and existing under the laws of the United States or any
               State thereof or the District of Columbia,  and such  corporation
               expressly  assumes all of our  obligations or the  obligations of
               the  guarantor,  as the case may be,  under  each  series of debt
               securities  or the related  guarantees,  as  applicable,  and the
               indenture; and

          (2)  immediately  before and  immediately  after giving effect to such
               transaction, no event of default and no event which, after notice
               or  passage  of time or both,  would  become an event of  default
               shall have occurred and be continuing.

     Notwithstanding  the foregoing,  any guarantor may consolidate  with, merge
with or into or transfer all or part of its  properties  and assets to us or any
of our other guarantors.

     See  "--Guarantees"  below  for a  discussion  of  the  termination  of the
guarantees.

Defeasance

     If it is specified in the applicable  prospectus  supplement that either or
both of defeasance or covenant  defeasance is applicable to the debt securities,
then we may  elect to have  these  options  apply to the  debt  securities  upon
satisfaction of certain conditions.

     If we are entitled to elect,  and we elect,  the  defeasance  option,  upon
satisfaction of the conditions  described  below, we will be deemed to have paid
and discharged the entire  indebtedness  represented by the debt securities and,
with  certain  exceptions,  to have  satisfied  our  obligations  under the debt
securities  and the  indenture.  If we are entitled to, and elect,  the covenant
defeasance  option,  we may omit to comply  with,  and will have no liability or
obligations with respect to, the covenants relating to merger,  consolidation or
sale of assets and restrictions on liens and sales and leasebacks.

     The following  are the  conditions  to the  applicability  of defeasance or
covenant defeasance as the case may be:

     (a) We must  irrevocably  deposit with the trustee funds for the purpose of
making the following payments, (1) in the case of debt securities denominated in
U.S. dollars, (A) an amount of cash, or (B) direct non-callable  obligations of,
or  guaranteed  by, the United  States of America,  which  through the scheduled
payment of principal and interest will provide, within two weeks of the due date
of any  payment,  money  in an  amount,  or  (C) a  combination  of  the  above,
sufficient, without reinvestment, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification delivered
to the trustee,  to pay and discharge,  the principal of,  premium,  if any, and
each installment of interest on such debt securities on their respective  stated
maturities  in  accordance  with the  terms of the  indenture  and of such  debt
securities,  or (2) in the case of debt securities denominated in currency other
than  U.S.  dollars,  an  amount  of  required  currency  sufficient  to pay and
discharge the principal of, premium, if any, and each installment of interest on
such  securities on their  respective  stated  maturities in accordance with the
terms of this indenture and of such securities.

     (b) No event of default or event with which notice or lapse of time or both
would  become an event of default  with  respect to such  securities  shall have
occurred  and be  continuing  on the date of the deposit  and,  with  respect to
defeasance only, at any time during the period ending on the 123rd day after the
date of the deposit.

     (c) Defeasance or covenant  defeasance  shall not cause the trustee for the
debt  securities  to have a  conflicting  interest  for purposes of the TIA with
respect to any debt securities.

     (d)  Defeasance  or  covenant  defeasance  shall not  result in a breach or
violation  of,  or  constitute  a  default  under,  the  indenture  or any other
agreement or instrument.

     (e) Such  defeasance  or  covenant  defeasance  shall  not  cause  any debt
securities then listed on any registered  national securities exchange under the
Securities Exchange Act of 1934, as amended, to be delisted.

     (f) In the case of a defeasance  election,  the trustee shall have received
an opinion of counsel  stating that (x) we have received from, or there has been
published by, the Internal  Revenue  Service a ruling,  or (y) since the date of
the indenture there has been a change in the applicable  federal income tax law,
in either case to the effect that,  and based thereon such opinion shall confirm
that,  the holders of the debt  securities  will not recognize  gain or loss for
federal  income tax  purposes as a result of  defeasance  and will be subject to
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such defeasance had not occurred.

     (g) In the case of a covenant defeasance  election,  the trustee shall have
received  an  opinion of  counsel  to the  effect  that the  holders of the debt
securities  will not  recognize  income,  gain or loss for  federal  income  tax
purposes  as a result of a  covenant  defeasance  and will be subject to federal
income  tax on the same  amounts,  in the same  manner  and at the same times as
would have been the case if such covenant defeasance had not occurred.

     (h) The trustee shall have received an officers'  certificate or an opinion
of counsel,  stating that all conditions precedent provided for in the indenture
have been complied with.

Discharge

     Generally,  we may be discharged from our  obligations  under the indenture
when

          (1)  all  outstanding  debt  securities  have  been  delivered  to the
               trustee for cancellation; or

          (2)  debt securities which have not been delivered to the Trustee have
               become due and  payable,  will  become  due and  payable at their
               stated  maturity  within one year or if redeemable at our option,
               will be called for redemption within one year and the Company has
               deposited  sufficient  funds with the  trustee to  discharge  the
               entire indebtedness with respect to such securities.

Modification and Waiver

     We, the  guarantors  and the trustee may amend or supplement  the indenture
with the  consent  of the  holders  of a  majority  in  principal  amount of the
outstanding  debt securities of all series affected  thereby (voting as a single
class);  provided,  however,  that such amendment or supplement may not, without
the consent of each holder of the debt securities affected thereby:

          (1)  reduce the amount of debt  securities  whose holders must consent
               to an amendment, supplement or waiver;

          (2)  reduce the rate (or change the manner of calculation of the rate)
               or change the stated maturity for payment of interest on any debt
               security;

          (3)  reduce  the  principal  of  or  any  premium   payable  upon  the
               redemption  of or change the stated  maturity  for payment of the
               principal of any debt security;

          (4)  waive a default in the payment of the principal of or premium, if
               any, or interest on any debt security;

          (5)  make any changes in the amount of debt  securities  whose holders
               may waive a default or event of default, the right of each holder
               to receive  payments of  principal  of and  premium,  if any, and
               interest on the debt  securities  on and after the due dates,  or
               the amendments, supplements or waivers which may only be effected
               with consent of each affected security holder;

          (6)  make any debt  security  payable  in a  currency  other than that
               stated in the debt security;

          (7)  impair the holders' right to institute suit to enforce payment in
               respect of the debt  securities on or after the due date for such
               payment; or

          (8)  release any guarantor from its obligations under any guarantee.

     Holders  of  a  majority  in  principal  amount  of  the  outstanding  debt
securities of all series  affected  thereby (voting as a single class) may waive
certain past  defaults and may waive  compliance by us with any provision of the
indenture relating to such debt securities (subject to the immediately preceding
paragraph); provided, however, that:

          (1)  without the consent of each  holder of debt  securities  affected
               thereby, no waiver may be made of a default in the payment of the
               principal  of or  premium,  if  any,  or  interest  on  any  debt
               security; and

          (2)  only  the  holders  of a  majority  in  principal  amount  of the
               outstanding  debt  securities  of a  particular  series may waive
               compliance  with a provision  of the  indenture  relating to such
               series or the debt securities of such series having applicability
               solely to such series.

Events of Default and Notice of Events of Default

     The following  events are "events of default" with respect to any series of
debt securities issued under the indenture:

          (1)  failure to pay  interest  on any debt  securities  of such series
               within 30 days of when due or principal of any debt securities of
               such series when due (including any sinking fund installment);

          (2)  failure  to perform  any other  agreement  contained  in the debt
               securities  of  such  series  or the  indenture  (other  than  an
               agreement  relating solely to another series of debt  securities)
               for 60 days after notice; and

          (3)  certain events of bankruptcy,  insolvency or reorganization  with
               respect to us or the guarantors.

     Additional or different events of default, if any, applicable to the series
of debt  securities in respect of which this  prospectus is being delivered will
be specified in the applicable prospectus supplement.

     The trustee under the indenture  will,  within 75 days after the occurrence
of any default (the term "default" to include the events specified above without
grace or notice) with respect to any series of debt securities actually known to
it, give to the holders of the debt securities notice of the default;  provided,
however, that, except in the case of a default in the payment of principal of or
premium,  if any, or interest on any of the debt  securities of the series or in
the payment of a sinking  fund  installment,  the trustee for the series will be
protected  in  withholding  notice  if it in  good  faith  determines  that  the
withholding of notice is in the interest of the holders of the debt  securities.
We will certify to the trustee quarterly as to whether any default exists.

     If an event of default with respect to any series of debt securities, other
than  an  event  of   default   resulting   from   bankruptcy,   insolvency   or
reorganization, shall occur and be continuing, the trustee for the series or the
holders of at least 25% in aggregate  principal amount of the debt securities of
the series then outstanding,  by notice in writing to us (and to the trustee for
the series if given by the holders of the debt  securities of the series),  will
be entitled to declare all unpaid principal of, premium, if any, and accrued but
unpaid interest on the debt securities of that series then outstanding to be due
and payable immediately.

     If an event of  default  with  respect  to any  series  of debt  securities
resulting from certain events of bankruptcy,  insolvency or reorganization shall
occur and be continuing,  all unpaid principal of, premium,  if any, and accrued
but unpaid interest on all debt securities of every series then outstanding will
be due and payable  immediately without any declaration or other act on the part
of the  trustee  for the  series or the  holders of any debt  securities  of the
series.

     The  holders of a majority  in  principal  amount of the  outstanding  debt
securities of a series may by notice to the trustee rescind an acceleration  and
its  consequences  if (i)  all  existing  events  of  default,  other  than  the
non-payment of the principal of the debt  securities  that has become due solely
by the declaration of acceleration,  have been cured or waived, (ii) interest on
overdue  installments of interest (to the extent lawful),  premium,  if any, and
overdue  principal,  that has become due otherwise  than by the  declaration  of
acceleration,  has been paid,  (iii) the rescission  would not conflict with any
judgment or decree of a court of  competent  jurisdiction  and (iv) all payments
due to the trustee have been made.

     No holder of the debt  securities  of any series issued under the indenture
may pursue any remedy  under the  indenture  unless the  trustee  for the series
shall  have  failed to act  after,  among  other  things,  notice of an event of
default  and  request  by  holders  of at least 25% in  principal  amount of the
outstanding  debt  securities of the series as to which the event of default has
occurred and the offer to the trustee for the series of  indemnity  satisfactory
to it; provided,  however,  that this provision does not affect the right to sue
for enforcement of any overdue payment on the debt securities.

Guarantees

          Indiana Gas,  Southern  Indiana Gas and Vectren of Ohio will,  jointly
and severally,  fully and unconditionally guarantee the performance and punctual
payment when due, whether at stated maturity,  by acceleration or otherwise,  of
all  of our  obligations  under  the  debt  securities  of any  series  and  the
provisions of the indenture  relating to the series. If we default in payment of
the  principal  of or  interest  or any  premium  on such debt  securities,  the
guarantors, jointly and severally, will be unconditionally obligated to duly and
punctually  make  such  payments.  The  liability  of  the  guarantors  will  be
independent of, and not in  consideration of or contingent upon our liability or
the  liability of any other party  obligated  under the debt  securities  or the
indenture.  Further,  Utility Holdings may in its sole discretion elect to cause
each  subsequent  subsidiary  of Utility  Holdings to fully and  unconditionally
guarantee all of the obligations under the debt security; provided however, that
Utility  Holdings  has  agreed to cause any  subsequent  subsidiary  of  Utility
Holdings that guarantees other  obligations of Utility Holdings to guarantee the
obligations under the debt securities.


     With respect to each  guarantor,  the guarantee will rank equal in right of
payment  with  all  of  the  guarantor's  other  unsecured  and   unsubordinated
indebtedness.

     Each  guarantor's  obligations  will be limited to the maximum  amount that
(after  giving  effect to all other  contingent  and fixed  liabilities  of such
guarantor  and any  collections  from,  or payments made by or on behalf of, any
guarantors) will result in the obligations of such guarantor under the guarantee
not constituting a fraudulent conveyance or fraudulent transfer under federal or
state law.

     Except as otherwise  specified in the following  paragraph,  the guarantees
will  remain  in full  force  and  effect  until  payment  in full of all of the
guaranteed obligations.

     Notwithstanding the restrictions on transfer described above in "-- Merger,
Consolidation or Sale of Assets," if we transfer or cause the transfer of all or
substantially  all of the voting capital stock or assets of any guarantor to any
person other than one of our other guarantors, whether by merger, consolidation,
sale or other transfer, all of the guarantor's obligations and liabilities under
the guarantee will terminate upon transfer so long as:

     (1)  the guarantor has fully repaid all of its indebtedness, if any, to us,

     (2)  Standard & Poor's  Ratings  Services,  a division  of The  McGraw-Hill
          Companies,  Inc.,  and  Moody's  Investors  Service,  Inc.,  or  their
          successors, have confirmed that, as a result of the transfer, our long
          term credit  rating will not fall below BBB- (or its  equivalent),  in
          the case of Standard & Poor's,  and Baa3 (or its  equivalent),  in the
          case of Moody's, and

     (3)  immediately  before  and  immediately  after  giving  effect  to  such
          transaction,  no event of default and no event which,  after notice or
          passage of time or both,  would become an event of default  shall have
          occurred and be continuing.

     The prospectus  supplement for a particular  issue of debt  securities will
describe any additional material terms of the guarantees.

The Trustee

     The  trustee  under  the  indenture   will  be  U.S.  Bank  Trust  National
Association.  The indenture will contain certain limitations on the right of the
trustee,  as our creditor,  to obtain payment of claims in certain cases,  or to
realize on certain property received in respect of any such claim as security or
otherwise.  The  trustee  will be  permitted  to engage  in other  transactions;
provided,  however,  that  if it  acquires  any  conflicting  interest,  it must
eliminate such conflict or resign.

     The  holders of a majority  in  principal  amount of all  outstanding  debt
securities of a series (or if more than one series is affected  thereby,  of all
series so affected,  voting as a single class) will have the right to direct the
time, method and place of conducting any proceeding for exercising any remedy or
power available to the trustee for such series or all such series so affected.

     In case an event of default  shall occur (and shall not be cured) under the
provisions  of the  indenture  relating  to a series of debt  securities  and is
actually  known to a  responsible  officer of the trustee  for the  series,  the
trustee  will  exercise  such  of the  rights  and  powers  vested  in it by the
indenture and use the same degree of care and skill in its exercise as a prudent
person would exercise or use under the  circumstances  in the conduct of his own
affairs.  Subject  to  such  provisions,  the  trustee  will  not be  under  any
obligation  to exercise any of its rights or powers  under the  indenture at the
request of any of the holders of debt securities  unless they shall have offered
to the trustee reasonable security or indemnity.

Governing Law

     The indenture,  the debt  securities and the guarantees will be governed by
the laws of the State of Indiana.

Global Securities; Book-Entry System

     We may issue the debt  securities  of any series in whole or in part in the
form of one or more global  securities to be deposited  with, or on behalf of, a
depository (the "depository")  identified in the prospectus  supplement relating
to such  series.  Global  securities,  if any,  issued in the United  States are
expected  to  be  deposited  with  The  Depository  Trust  Company  ("DTC"),  as
depository. Global securities will be issued in fully registered form and may be
issued in either  temporary or permanent form.  Unless and until it is exchanged
in whole or in part for the individual debt securities  represented  thereby,  a
global  security may not be transferred  except as a whole by the depository for
the  global  security  to a nominee  of the  depository  or by a nominee  of the
depository  to the  depository  or another  nominee of the  depository or by the
depository  or any nominee of the  depository  to a successor  depository or any
nominee of the successor.

     The specific terms of the depository arrangement with respect to any series
of debt  securities will be described in the prospectus  supplement  relating to
the  series.  We  expect  that  unless  otherwise  indicated  in the  applicable
prospectus  supplement,  the  following  provisions  will  apply  to  depository
arrangements.

     Upon the  issuance  of a global  security,  the  depository  for the global
security or its nominee will credit on its book-entry  registration and transfer
system the  respective  principal  amounts  of the  individual  debt  securities
represented by the global security to the accounts of persons that have accounts
with the  depository  ("participants").  Such accounts will be designated by the
underwriters,  dealers or agents with respect to the debt securities or by us if
the  debt  securities  are  offered  directly  by us.  Ownership  of  beneficial
interests in the global security will be limited to participants or persons that
may hold interests through participants.

     We expect that,  pursuant to procedures  established  by DTC,  ownership of
beneficial  interests  in any global  security  with respect to which DTC is the
depository will be shown on, and the transfer of that ownership will be effected
only  through,  records  maintained  by DTC  or its  nominee  (with  respect  to
beneficial  interests of participants) and records of participants (with respect
to beneficial  interests of persons who hold through  participants).  Neither we
nor the trustee will have any  responsibility or liability for any aspect of the
records of DTC or for  maintaining,  supervising or reviewing any records of DTC
or any of its  participants  relating to beneficial  ownership  interests in the
debt  securities.  The laws of some states  require that certain  purchasers  of
securities  take physical  delivery of the securities in definitive  form.  Such
limits and laws may impair the  ability to own,  pledge or  transfer  beneficial
interest in a global security.

     So long as the  depository  for a global  security  or its  nominee  is the
registered holder of the global security,  the depository or the nominee, as the
case  may  be,  will  be  considered  the  sole  owner  of the  debt  securities
represented by the global security for all purposes under the indenture.  Except
as  described  below  or in the  applicable  prospectus  supplement,  owners  of
beneficial interest in a global security will not be entitled to have any of the
individual  debt  securities  represented by the global  security  registered in
their names, will not receive or be entitled to receive physical delivery of any
debt  securities  in definitive  form and will not be  considered  the owners or
holders of the debt securities  under the indenture.  Beneficial  owners of debt
securities  evidenced by a global  security will not be considered the owners or
holders of the debt  securities  under the indenture for any purpose,  including
with respect to the giving of any  direction,  instructions  or approvals to the
trustee  under the  indenture.  Accordingly,  each  person  owning a  beneficial
interest in a global  security with respect to which DTC is the depository  must
rely on the procedures of DTC and, if such person is not a  participant,  on the
procedures of the participant  through which such person owns its interests,  to
exercise any rights of a holder under the indenture.  We understand  that, under
existing industry  practice,  if we request any action of holders or if an owner
of a beneficial interest in a global security desires to give or take any action
which a holder  is  entitled  to give or take  under  the  indenture,  DTC would
authorize the participants  holding the relevant  beneficial interest to give or
take such action, and the participants would authorize beneficial owners through
the  participants  to give or take such actions or would  otherwise act upon the
instructions of beneficial owners holding through them.

     Payments of principal of, and any premium and interest on,  individual debt
securities  represented  by a  global  security  registered  in  the  name  of a
depository or its nominee will be made to or at the direction of the  depository
or its  nominee,  as the  case may be,  as the  registered  owner of the  global
security  under the  indenture.  Under the  terms of the  indenture,  we and the
trustee may treat the persons in whose name debt securities,  including a global
security, are registered as the owners of the debt securities for the purpose of
receiving  payments.  Consequently,  neither we nor the trustee has or will have
any  responsibility  or liability  for the payment of such amounts to beneficial
owners of debt  securities  (including  principal  and  interest).  We  believe,
however,  that it is  currently  the  policy of DTC to  immediately  credit  the
accounts of relevant  participants with such payments,  in amounts proportionate
to their  respective  holdings of  beneficial  interests in the relevant  global
security  as shown on the  records of DTC or its  nominee.  We also  expect that
payments  by  participants  to  owners of  beneficial  interests  in the  global
security held through participants will be governed by standing instructions and
customary  practices,  as is the case with  securities  held for the  account of
customers  in  bearer  form  or  registered  in  street  name,  and  will be the
responsibility of the participants.  Redemption notices with respect to any debt
securities  represented  by a global  security will be sent to the depository or
its  nominee.  If less than all of the debt  securities  of any series are to be
redeemed,  we expect the  depository  to determine the amount of the interest of
each  participant in the debt securities to be redeemed to be determined by lot.
None of us,  the  trustee,  any  paying  agent  or the  registrar  for the  debt
securities  will have any  responsibility  or  liability  for any  aspect of the
records  relating  to or  payments  made  on  account  of  beneficial  ownership
interests in the global  security for the debt securities or for maintaining any
records with respect to the debt securities.

     Neither we nor the trustee will be liable for any delay by the holders of a
global security or the depository in identifying  the beneficial  owners of debt
securities  and we and  the  trustee  may  conclusively  rely  on,  and  will be
protected in relying on,  instructions  from the holder of a global  security or
the  depository  for  all  purposes.   The  rules  applicable  to  DTC  and  its
participants are on file with the Securities and Exchange Commission.

     If a depository for any debt securities is at any time unwilling, unable or
ineligible to continue as depository and a successor depository is not appointed
by us within 90 days or if an event of default under the indenture occurs and is
continuing,  we will issue individual debt securities in exchange for the global
security  representing the debt securities.  In addition, we may at any time and
in our sole discretion,  subject to any limitations  described in the prospectus
supplement  relating to the debt  securities,  determine  not to have any of the
debt securities  represented by one or more global  securities and in such event
will issue  individual  debt  securities in exchange for the global  security or
securities  representing  the debt  securities.  Individual  debt  securities so
issued will be issued in denominations of $1,000 and integral multiples thereof.

     All moneys paid by us to a paying agent or a trustee for the payment of the
principal of or interest on any debt security which remain  unclaimed at the end
of two years after such payment has become due and payable will be repaid to us,
and the holder of such debt security  thereafter may look only to us for payment
thereof.







                              PLAN OF DISTRIBUTION

     We may sell securities:

     o    to the public through underwriters,

     o    to private investors through agents or dealers,

     o    directly to purchasers.

     In  connection  with  the  sale of the debt  securities,  underwriters  may
receive  compensation from us or from purchasers of the debt securities for whom
they may act as agents in the form of  discounts,  concessions  or  commissions.
Underwriters  may sell the  debt  securities  to or  through  dealers,  and such
dealers  may  receive  compensation  in the form of  discounts,  concessions  or
commissions  from the  underwriters  and/or  commissions from the purchasers for
whom they may act as agents.  Underwriters,  dealers and agents that participate
in the distribution of the debt securities may be deemed to be underwriters, and
any  discounts  or  commissions  received  by them from us and any profit on the
resale of the debt securities by them may be deemed to be underwriting discounts
and  commissions  under the Securities Act of 1933. Any  underwriter,  dealer or
agent will be  identified,  and any such  compensation  received from us will be
described, in a prospectus supplement or pricing supplement.

     If  so  indicated  in  the   prospectus   supplement,   we  will  authorize
underwriters  to  solicit  offers  by  certain  institutions  to  purchase  debt
securities from us pursuant to delayed delivery contracts  providing for payment
and delivery on the date stated in the prospectus supplement. Each contract will
be for an amount not less than the amount stated in the  prospectus  supplement,
and,  unless  we  otherwise  agree,  the  aggregate  principal  amount  of  debt
securities  sold  pursuant to the  contracts  will not be more than,  the amount
stated in the prospectus supplement.  Institutions with whom the contracts, when
authorized,  may  be  made  include  commercial  and  savings  banks,  insurance
companies,  pension  funds,  investment  companies,  educational  and charitable
institutions,  and other institutions,  but shall in all cases be subject to our
approval.  Delayed  delivery  contracts  will not be subject  to any  conditions
except that the purchase by an institution of the debt securities  covered under
that contract shall not at the time of delivery be prohibited  under the laws of
any jurisdiction in the United States to which that institution is subject.

     We will  indemnify the agents and the  underwriters  against  certain civil
liabilities,  including  liabilities  under  the  Securities  Act  of  1933,  or
contribute to payments the agents or the underwriters may be required to make.

Item 15.          Indemnification of Directors and Officers.


Utility Holdings Indemnification Provisions

     Our articles of incorporation provide that we are required to indemnify any
person  who  was or is a  party  or is  threatened  to be  made a  party  to any
threatened,  pending or completed action,  suit or proceeding,  whether civil or
criminal,  administrative,  investigative,  formal or  informal by reason of the
fact  that he is or was a  director,  officer,  employee  or  agent  of  Utility
Holdings  or is or was serving at our  request as a  director,  officer,  agent,
employee,  partner,  trustee  or member in another  corporation,  unincorporated
association,  business trust, estate, partnership, trust, joint venture or other
entity against expenses  (including  attorneys' fees) and judgments,  penalties,
fines and amounts paid in settlement if the person (1) acted in good faith,  (2)
acted in a manner he  reasonably  believed  (A) with  respect  to actions in his
official  capacity,  to be in the best interests of Utility Holdings or (B) with
respect to actions  not in the  official  capacity,  was not opposed to the best
interests  of Utility  Holdings  and (3) with  respect to any  criminal  action,
either (A) had reasonable  cause to believe his conduct was lawful or (B) had no
reasonable cause to believe his conduct was unlawful.

     Further,  we must indemnify any such person against expenses if such person
has been successful on the merits or otherwise in the defense of the action.

     Unless ordered by court,  any  indemnification  of a person pursuant to the
provisions  described  in the first  paragraph of this section may be made by us
only  as   authorized   in  the  specific   case  upon  a   determination   that
indemnification of the person is proper in the circumstances  because he met the
applicable  indemnification  standards.  Such determination shall be made (i) by
our board of directors,  by a majority vote of a quorum  consisting of directors
who are not parties to the action or  proceeding  or (ii) if a quorum  cannot be
obtained,  by a majority  vote of a committee  duly  designated by the board (in
which designation  directors who are parties may participate)  consisting solely
of two or more  directors  who are not  parties to the action or  proceeding  or
(iii) by written opinion of independent  legal counsel (A) selected by the board
in the  manner  described  in (i) or (ii)  above  or (B) if a quorum  cannot  be
obtained or a committee cannot be designated, selected by a majority of the full
board in which  selection  directors who are parties may  participate or (iv) by
shareholders who are not parties.

     We may advance  expenses  reasonably  incurred in  defending  any action or
proceeding  described  above  if (i) the  person  furnishes  us  with a  written
affirmation of a good faith belief that he has met the indemnification standards
and a written  undertaking  to repay the advance if it is ultimately  determined
that he did not meet the  indemnification  standards  and (ii) it is  determined
that the facts then known  would not  preclude  indemnification  pursuant to the
provision described above.

     Our articles provide that the indemnification  provisions are not exclusive
of other indemnification rights which a person may have under law, the bylaws, a
resolution  of  the  board  or  shareholders,  or  any  other  authorization  or
instrument providing for indemnification.  The articles provide that we have the
power to  maintain  insurance  on behalf of the  directors,  officers  and other
persons  described above against  liabilities  whether or not we would otherwise
have the power to indemnify against such liability.

Southern Indiana Gas Indemnification Provisions

     The  Southern  Indiana Gas bylaws  provide that  Southern  Indiana Gas will
indemnify any individual who is or was a director or officer of Southern Indiana
Gas,  or served at the  request  of  Southern  Indiana  Gas in any  position  or
capacity or on any committee for Southern Indiana Gas or any other  corporation,
partnership,   association,   trust,  foundation,   not-for-profit  corporation,
employee benefit plan or other organization or entity, against all liability and
reasonable  expenses,  including  attorneys  fees,  incurred  by such  person in
connection  with or resulting  from any claim,  action,  suit,  or proceeding in
which either (i) such person is wholly  successful on the merits thus  entitling
such  person to  mandatory  indemnification  or (ii) such  person is not  wholly
successful  but it is  nevertheless  determined  that such person is entitled to
permissive  indemnification  because  such person (a) acted in good  faith,  (b)
acted in a manner he  reasonably  believed  (1) with  respect  to actions in his
official  capacity,  to be in the best interests of Southern  Indiana Gas or (2)
with  respect  to all  other  actions,  was at  least  not  opposed  to the best
interests of Southern  Indiana Gas and (c) with respect to any criminal  action,
either (1) had reasonable  cause to believe his conduct was lawful or (2) had no
reasonable cause to believe his conduct was unlawful.

     Any  indemnification  of a person  pursuant to the provisions  described in
clause (ii) above may be made by Southern  Indiana Gas only as authorized in the
specific case upon a determination that  indemnification of the person is proper
in the circumstances  because he met the applicable  indemnification  standards.
Upon a proposal by a director of the  corporation,  who may be a director who is
seeking such  indemnification for himself, (i) if a quorum of directors eligible
to decide the matter  exists,  such directors may either (a) decide the question
themselves,  (b) refer the matter to special  legal  counsel,  or (c) decline to
take any action to either decide the question of such  indemnification  or refer
the matter for decision to special legal counsel; and (ii) if a quorum cannot be
obtained,  a majority of the entire board of directors  may either (a) refer the
matter to a committee consisting of two or more directors who are not parties to
the action or proceeding,  who may either decide the matter  themselves or refer
the matter to special  legal counsel or (b) decline to take any action to either
refer the matter to a committee or refer the matter to special legal counsel.

     Southern Indiana Gas may pay for or reimburse  reasonable expenses incurred
by a director or officer in defending any action, suit, or proceeding in advance
of the final  disposition  thereof upon receipt of (i) a written  affirmation of
the  director's or officer's good faith belief that such director or officer has
met the standard of conduct  prescribed by Indiana law; and (ii) an  undertaking
of the  director or officer to repay the amount paid by Southern  Indiana Gas if
it is  ultimately  determined  that the  director or officer is not  entitled to
indemnification by Southern Indiana Gas.

     The  Southern  Indiana Gas  articles  and the  Southern  Indiana Gas bylaws
provide  that the  indemnification  rights  described  above are in addition any
other indemnification  rights a person may have by law or by contract.  Southern
Indiana Gas expects that employment  agreements with its executive officers will
require Southern  Indiana Gas to indemnify the executive  officers in accordance
with  its  indemnification  policies  for  its  senior  executives,  subject  to
applicable law.

Indiana Gas Indemnification Provisions

     The  articles of  incorporation  of Indiana Gas provide that Indiana Gas is
required to indemnify  any person who was or is a party or is  threatened  to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil or criminal, administrative,  investigative, formal or informal by
reason of the fact that he is or was a director,  officer,  employee or agent of
Indiana  Gas or is or was  serving at the  request of Indiana Gas as a director,
officer,  agent,  employee,  partner,  trustee or member in another corporation,
unincorporated association,  business trust, estate,  partnership,  trust, joint
venture  or other  entity  against  expenses  (including  attorneys'  fees)  and
judgments,  penalties,  fines and amounts paid in  settlement  if the person (1)
acted in good  faith,  (2) acted in a manner  he  reasonably  believed  (A) with
respect to actions in his  official  capacity,  to be in the best  interests  of
Indiana Gas or (B) with respect to actions not in the official capacity, was not
opposed  to the  best  interests  of  Indiana  Gas and (3) with  respect  to any
criminal  action,  either (A) had  reasonable  cause to believe  his conduct was
lawful or (B) had no reasonable cause to believe his conduct was unlawful.

     Further,  Indiana Gas must  indemnify any such person  against  expenses if
such person has been successful on the merits or otherwise in the defense of the
action.

     Unless ordered by a court, any  indemnification of a person pursuant to the
provisions  described  in the first  paragraph  of this  section  may be made by
Indiana Gas only as authorized in the specific  case upon a  determination  that
indemnification of the person is proper in the circumstances  because he met the
application  indemnification  standards. Such determination shall be made (i) by
the board of directors,  by a majority vote of a quorum  consisting of directors
who are not parties to the action or  proceeding  or (ii) if a quorum  cannot be
obtained,  by a majority  vote of a committee  duly  designated by the board (in
which designation  directors who are parties may participate)  consisting solely
of two or more  directors  who are not  parties to the action or  proceeding  or
(iii) by written opinion of independent  legal counsel (A) selected by the board
in the  manner  described  in (i) or (ii)  above  or (B) if a quorum  cannot  be
obtained or a committee cannot be designated, selected by a majority of the full
board in which  selection  directors who are parties may  participate or (iv) by
shareholders who are not parties.

     Indiana Gas may advance  expenses  reasonably  incurred  in  defending  any
action or proceeding  described  above if (i) the person  furnishes  Indiana Gas
with  a  written  affirmation  of a good  faith  belief  that  he  has  met  the
indemnification  standards and a written  undertaking to repay the advance if it
is ultimately determined that he did not meet the indemnification  standards and
(ii)  it  is   determined   that  the  facts  then  known  would  not   preclude
indemnification pursuant to the provision described above.

     The articles provide that the indemnification  provisions are not exclusive
of  other  indemnification  rights  which a  person  may  have  under  law,  the
regulations and bylaws, a resolution of the board or shareholders,  or any other
authorization or instrument providing for indemnification.  The articles provide
that Indiana Gas has the power to maintain insurance on behalf of the directors,
officers and other persons  described above against  liabilities  whether or not
Indiana Gas would otherwise have the power to indemnify against such liability.

Indiana Business Corporation Law Provision

     Section  23-1-37 et seq. of the Indiana  Business  Corporation Law ("IBCL")
provides for "mandatory  indemnification,"  unless limited by the articles, by a
corporation  against  reasonable  expenses  incurred by a director who is wholly
successful,  on the merits or  otherwise,  in the defense of any  proceeding  to
which the director was a party by reason of the director  being or having been a
director  of the  corporation.  Section  23-1-37-10  of the IBCL  states  that a
corporation may, in advance of the final disposition of a proceeding,  reimburse
reasonable expenses incurred by a director who is a party to a proceeding if the
director furnishes the corporation with a written  affirmation of the director's
good faith belief that the director acted in good faith and reasonably  believed
the actions were in the best interest of the  corporation if the proceeding is a
civil  proceeding.  If the  proceeding is criminal,  the director must furnish a
written  affirmation that the director had reasonable cause to believe he or she
was acting  lawfully  or the  director  or officer  had no reason to believe the
action was  unlawful.  The director  will repay the advance if it is  ultimately
determined  that such director did not meet the standard of conduct  required by
the IBCL and that those making the decision to reimburse the director  determine
that the facts then known would not preclude indemnification under the IBCL.

     The IBCL permits a corporation to grant indemnification  rights in addition
to those  provided  by  statute,  limited  only by the  fiduciary  duties of the
directors  approving  the  indemnification  and public  policies of the State of
Indiana.

Vectren of Ohio Indemnification Provisions

     The code of  regulations of Vectren of Ohio provide that Vectren of Ohio is
required to indemnify  any person who is a party,  or is threatened to be made a
party, to any civil,  criminal,  administrative,  or investigative action, other
than an action by or in the right of the corporation, by reason of the fact that
he is or was a director,  officer, employee, or agent of the corporation,  or is
or was  serving  at the  request  of the  corporation  as a  director,  trustee,
officer,  employee,  or agent  of  another  corporation,  domestic  or  foreign,
nonprofit or for profit, partnership, joint venture, trust, or other enterprise,
against  expenses,   including  attorney's  fees,  judgments,   decrees,  fines,
penalties,  and amounts paid in settlement  actually and reasonably  incurred by
him in  connection  with such action,  suit or  proceeding,  if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests  of the  corporation,  and with  respect to any  criminal  action,  or
proceeding, he had no reasonable cause to believe that his conduct was unlawful.

     In case any such person is a party or is  threatened  to be made a party to
any threatened,  pending,  or completed action or suit by or in the right of the
corporation  to procure a judgment  in its  favor,  further,  Vectren of Ohio is
required to indemnify these persons against expenses, including attorney's fees,
actually  and  reasonably  incurred  by him in  connection  with the  defense or
settlement of an action or suit  referenced  above if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the corporation,  except that no indemnification  shall be made in respect of
any of the following: (i) any claim, issue, or matter as to which such person is
adjudged to be liable for  negligence or misconduct  in the  performance  of his
duty to the  corporation  unless and only to the extent that the court of common
pleas,  or the court in which such  action or suit was brought  determines  upon
application that, despite the adjudication of liability,  but in view of all the
circumstances  of the case,  such  person is fairly and  reasonably  entitled to
indemnity  for such  expenses  as the court of common  pleas or such other court
shall  deem  proper;  or (ii) any  action  or suit in which  the only  liability
asserted  against a director is pursuant to Section  1701.95 of the Ohio Revised
Code.

     To the extent  that any such  person has been  successful  on the merits or
otherwise  in defense of any  action,  suit,  or  proceeding  referred to above,
Vectren of Ohio must indemnify him against expenses,  including attorney's fees,
actually and reasonably  incurred by him in connection with the action,  suit or
proceeding.

     Indemnification,  unless  ordered  by a court,  shall be made by Vectren of
Ohio  only  as  authorized  in  the  specific  case  upon a  determination  that
indemnification of the person is proper in the circumstances  because he has met
the applicable  standard of conduct set forth above. The determination  shall be
made as follows:  (i) by a majority vote of a quorum  consisting of directors of
the  corporation who were not and are not parties to or threatened with any such
action,  suit,  or  proceeding,  (ii) if this quorum is not  obtainable  or if a
majority vote of a quorum of  disinterested  directors so directs,  in a written
opinion by  independent  legal counsel other than an attorney,  or a firm having
associated  with it an attorney,  who has been  retained by or who has performed
services for the  corporation,  or any person to be indemnified  within the past
five years,  (iii) by the shareholders,  or (iv) by the court of common pleas or
the  court  in  which  such  action,   suit,  or  proceeding  has  brought.  Any
determination  made  by the  disinterested  directors  or by  independent  legal
counsel must be promptly  communicated  to the person who  threatened or brought
the action or suit, by or in the right of the  corporation,  and within ten days
after the  receipt  of the  notification,  such  person  shall have the right to
petition the court of common pleas or the court in which such action or suit was
brought to review the reasonableness of such determination.

     Unless the only liability  asserted against a director in an action,  suit,
or proceeding is pursuant to Section 1701.95 of the Ohio Revised Code, expenses,
including attorney's fees, incurred by a director in defending the action, suit,
or proceeding, shall be paid by the corporation as they are incurred, in advance
of the final  disposition of the action,  suit, or proceeding upon receipt of an
undertaking by or on behalf of the director in which he agrees to do both of the
following:  (A) repay  such  amount  if it is  proved  by clear  and  convincing
evidence in a court of competent  jurisdiction that his action or failure to act
involved an act or omission undertaken with deliberate intent to cause injury to
the corporation or undertaken with reckless  disregard for the best interests of
the corporation;  and (B) reasonably  cooperate with the corporation  concerning
the action, suit, or proceeding.

     Expenses,  including  attorney's  fees,  incurred by a  director,  trustee,
officer,  employee or agent in defending any action, suit or proceeding referred
to above may be paid by the  corporation  as they are incurred in advance of the
final  disposition  of the  action,  suit or  proceeding  as  authorized  by the
directors  in the  specific  case upon the  receipt of an  undertaking  by or on
behalf of the  director,  trustee,  officer,  employee,  or agent to repay  such
amount, if it ultimately is determined that he is not entitled to be indemnified
by the corporation.

     Expenses,  including  attorneys'  fees,  amounts  paid in  settlement,  and
(except  in the  case  of an  action  by or in  the  right  of the  corporation)
judgments,  decrees,  fines  and  penalties,  incurred  in  connection  with any
potential,  threatened, pending or completed action, suit or proceeding, whether
civil, criminal,  administrative or investigative by any person by reason of the
fact that he is or was a director, officer, employee or agent of the corporation
or is or was serving at the request of the  corporation as a director,  trustee,
officer,  employee,  or agent  of  another  corporation,  domestic  or  foreign,
nonprofit or profit, partnership,  joint venture, trust or other enterprise, may
be  paid or  reimbursed  by the  corporation,  as  authorized  by the  board  of
directors upon a determination  that such payment or  reimbursement  is the best
interests of the corporation;  provided,  however, that unless all directors are
interested, the interested directors shall not participate and a quorum shall be
one-third of the disinterested directors.

     The indemnification  authorized by the code of regulations is not exclusive
of, and shall be in  addition  to,  any other  rights  granted to those  seeking
indemnification under the corporation's Articles of Incorporation or the code of
regulations or any agreement,  vote of shareholders or disinterested  directors,
or  otherwise,  both as to action in an  official  capacity  and as to action in
another  capacity  while holding such office,  and shall continue as to a person
who has ceased to be a director,  trustee, officer, employee, or agent and shall
inure to the benefit of the heirs, executors, and administrators of such person.

     Vectren of Ohio may  purchase and  maintain  insurance  or furnish  similar
protection,  including  but not  limited  to trust  funds,  letters of credit or
self-insurance,  on  behalf  of or for  any  person  who  is or was a  director,
officer,  employee,  or agent of the  corporation,  or is or was  serving at the
request of the corporation as a director,  trustee, officer,  employee, or agent
of  another  corporation,   domestic  or  foreign,   nonprofit  or  for  profit,
partnership,  joint venture,  trust or other  enterprise,  against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such,  whether or not the corporation  would have  indemnified him
against such liability under the provisions  described herein.  Insurance may be
purchased  from or  maintained  with a person  in which  the  corporation  has a
financial interest.

Ohio Revised Code Provisions

     Section   1701.13(E)   of  the  Ohio  Revised  Code  gives  a   corporation
incorporated  under the laws of Ohio power to indemnify any person who is or has
been a director,  officer, agent or employee of that corporation,  or of another
corporation,  domestic or foreign,  non-profit or for profit,  limited liability
company or a partnership,  joint venture or other enterprise,  at the request of
that corporation,  against expenses  actually and reasonably  incurred by him in
connection with any pending, threatened or completed action, suit or proceeding,
criminal or civil,  to which he was, is or may be made a party  because of being
or having been such  director,  officer or  employee,  provided,  in  connection
therewith,  that such person is  determined to have acted in good faith and in a
manner he reasonably  believed to be in or not opposed to the best  interests of
the  corporation,  that,  in the case of an action or suit by or in the right of
the corporation, (i) no negligence or misconduct shall have been adjudged unless
a court  determines  that such  person  is fairly  and  reasonably  entitled  to
indemnity,  and (ii) the  action or suit is not one in which the only  liability
asserted  against a director is pursuant to Section  1701.95 of the Ohio Revised
Code,  which relates to unlawful loans,  dividends and  distributions of assets,
and that,  in the case of a criminal  matter,  such person is determined to have
had no  reasonable  cause to believe  that his  conduct  was  unlawful.  Section
1701.13(E)  further  provides  that to the  extent  that  such  person  has been
successful  on the merits or otherwise in defense of any such action,  suit,  or
proceeding,  or in defense of any claim,  issue or matter  therein,  he shall be
indemnified against expenses, including attorneys' fees, actually and reasonably
incurred by him in connection  therewith.  Section  1701.13(E)  further provides
that  unless a  corporation  has  specifically  elected to the  contrary  in its
articles of  incorporation  or code of regulations and unless the only liability
asserted against a director is pursuant to Section 1701.95, expenses incurred by
a director in defending such an action,  suit or proceeding shall be paid by the
corporation  as they are  incurred in advance of the final  disposition  of such
action,  suit or  proceeding  upon receipt of an  undertaking  (i) to repay such
amounts if it is proved by clear and convincing evidence in a court of competent
jurisdiction  that such director acted, or failed to act, with deliberate intent
to cause  injury to the  corporation  or with  reckless  disregard  for the best
interests  of  the  corporation  and  (ii)  reasonably  to  cooperate  with  the
corporation concerning said action, suit or proceeding.  Section 1701.13(E) also
provides that the  indemnification  thereby  permitted shall not be exclusive of
any other  rights that  directors,  officers or  employees  may have,  including
rights under insurance purchased by the corporation.

Item 17.          Undertakings.

          Each of the undersigned Registrants hereby undertakes:

                    (1) To file,  during any period in which offers or sales are
          being made, a post-effective amendment to this registration statement:
          (i) to include  any  prospectus  required  by Section  10(a)(3) of the
          Securities Act of 1933 (the "Securities  Act"); (ii) to reflect in the
          prospectus any facts or events arising after the effective date of the
          registration  statement (or the most recent  post-effective  amendment
          thereof)  which,  individually  or  in  the  aggregate,   represent  a
          fundamental  change in the information  set forth in the  Registration
          Statement.  Notwithstanding the foregoing, any increase or decrease in
          volume of securities  offered (if the total dollar value of securities
          offered would not exceed that which was  registered) and any deviation
          from the low or high end of the estimated  maximum  offering range may
          be  reflected  in the form of  prospectus  filed  with the  Commission
          pursuant  to Rule 424(b) if, in the  aggregate,  the changes in volume
          and price  represent  no more than a 20 percent  change in the maximum
          aggregate offering price set forth in the "Calculation of Registration
          Fee"  table in the  effective  registration  statement;  and  (iii) to
          include  any  material   information  with  respect  to  the  plan  of
          distribution not previously disclosed in the Registration Statement or
          any material change to such information in the Registration Statement.
          Provided,  however,  that  (1)(i)  and  (1)(ii)  do not  apply  if the
          information  required to be included in a post-effective  amendment by
          such clauses is contained in periodic  reports filed with or furnished
          to the Securities and Exchange  Commission by the Registrant  pursuant
          to Section 13 or Section 15(d) of the Securities  Exchange Act of 1934
          (the  "Exchange  Act")  that  are  incorporated  by  reference  to the
          Registration Statement.

                    (2) That, for the purpose of determining any liability under
          the Securities  Act, each  post-effective  amendment shall be deemed a
          new registration statement relating to the securities offered therein,
          and the offering of such securities at that time shall be deemed to be
          the initial bona fide offering thereof.

                    (3) To remove from registration by means of a post-effective
          amendment any of the securities  being  registered which remain unsold
          at the termination of the offering.

                    (4) That,  for purposes of determining  any liability  under
          the  Securities  Act,  each filing of the  Registrant's  annual report
          pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is
          incorporated  by reference  in this  Registration  Statement  shall be
          deemed to be a new registration  statement  relating to the securities
          offered  therein,  and the  offering of such  securities  at that time
          shall be deemed to be the initial bona fide offering thereof.

                    (5) Insofar as indemnification for liabilities arising under
          the  Securities  Act  may be  permitted  to  directors,  officers  and
          controlling  persons  of the  Registrant  pursuant  to the  provisions
          described under Item 15 above,  or otherwise,  the Registrant has been
          advised that in the opinion of the Securities and Exchange  Commission
          such  indemnification  is against  public  policy as  expressed in the
          Securities Act and is, therefore,  unenforceable.  In the event that a
          claim for  indemnification  against such  liabilities,  other than the
          payment by the Registrant of expenses  incurred or paid by a director,
          officer or  controlling  person of the  Registrant  in the  successful
          defense  of any  action,  suit  or  proceeding,  is  asserted  by such
          director,  officer  or  controlling  person  in  connection  with  the
          securities  being  registered,  the  Registrant  will,  unless  in the
          opinion of its  counsel  the matter  has been  settled by  controlling
          precedent,  submit to a court of appropriate jurisdiction the question
          whether  such  indemnification  by  it is  against  public  policy  as
          expressed  in the  Securities  Act and will be  governed  by the final
          adjudication of such issue.

                    (6) That,  for purposes of determining  any liability  under
          the Securities Act of 1933, the  information  omitted from the form of
          prospectus  filed as part of this  registration  statement in reliance
          upon  Rule 430A and  contained  in a form of  prospectus  filed by the
          registrant  pursuant  to Rule  424(b)(1)  or (4) or  497(h)  under the
