Item 4.  Description of Securities.

     Not applicable.

Item 5.  Interests of Named Experts and Counsel.

     Not applicable.

Item 6.  Indemnification of Directors and Officers.

     Vectren's Articles and bylaws provide that Vectren will
indemnify any individual who is or was a director or officer of
Vectren, or is or was serving at the request of Vectren as a
director, officer, partner or trustee of another foreign or
domestic corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise whether or not for profit,
against liability and expenses, including attorneys fees,
incurred by him in any action, suit, or proceeding, whether
civil, criminal, administrative, or investigative, and whether
formal or informal, in which he is made or threatened to be made
a party by reason of being or having been in any such capacity,
or arising out of his status as such, except (i) in the case of
any action, suit, or proceeding terminated by judgment, order, or
conviction, in relation to matters as to which he is adjudged to
have breached or failed to perform the duties of his office and
the breach or failure to perform constituted willful misconduct
or recklessness; and (ii) in any other situation, in relation to
matters as to which it is found by a majority of a committee
composed of all directors not involved in the matter in
controversy (whether or not a quorum) that the person breached or
failed to perform the duties of his office and the breach or
failure to perform constituted willful misconduct or
recklessness.  Vectren 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 Vectren if it is ultimately determined that
the director or officer is not entitled to indemnification by
Vectren.

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

     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 proceedings 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.  A
determination must also be made that the facts then known to
those making the determination would not preclude
indemnification.  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.

     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 maintains directors' and officers' liability
insurance with an annual aggregate limit of $35,000,000 for the
current policy period, subject to a $500,000 deductible at the
corporate level, for each wrongful act where corporate
reimbursement is available to any director or officer.  Vectren
also maintains excess coverage with an aggregate annual limit of
$90,000,000. When corporate reimbursement is not available as
prescribed by applicable common law, statutory law or Vectren's
governing documents, the insurer will reimburse the directors and
officers with no deductible with respect to losses sustained by
them for specified wrongful acts while acting in their
capacities, individually or collectively, as such directors or
officers.

Item 7.  Exemption from Registration Claimed.

     Not applicable.

Item 9.  Undertakings.

     (a)  The undersigned registrant 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;

               (ii) To reflect in the prospectus any facts or events
     arising after the effective date hereof (or the most recent
     post-effective amendment hereof) which, individually or in
     the aggregate, represent a fundamental change in the
     information set forth in this registration statement;

               (iii)     To include any material information with
     respect to the plan of distribution not previously disclosed
     in this registration statement or any material change to
     such information in this registration statement;

provided, however, that the undertakings set forth in paragraphs
(i) and (ii) above do not apply if the information required to be
included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the registrant pursuant to
section 13 or section 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in this registration
statement.

     (2)  That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective
amendment 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.

     (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.

     (b)  The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of
1933, each filing of the registrant's annual report pursuant to
section 13(a) or section 15(d) of the Securities Exchange Act of
1934 (and each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Securities Exchange Act of 1934)
that is incorporated by reference in the 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.

     (c)  Insofar as indemnification for liabilities arising
under the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the registrant pursuant to
the foregoing provisions, 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 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 Act and will be governed by the final adjudication of such
issue.

                           SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933,
the registrant certifies that it has reasonable grounds to
believe that it meets all of the requirements for filing on Form
S-8 and has duly caused this registration statement to be signed
on its behalf by the undersigned thereunto duly authorized, in
the City of Evansville, State of Indiana, on March 30, 2000.

Item 4.  Description of Securities.

     Not applicable.

Item 5.  Interests of Named Experts and Counsel.

     Not applicable.

Item 6.  Indemnification of Directors and Officers.

     Vectren's Articles and bylaws provide that Vectren will
indemnify any individual who is or was a director or officer of
Vectren, or is or was serving at the request of Vectren as a
director, officer, partner or trustee of another foreign or
domestic corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise whether or not for profit,
against liability and expenses, including attorneys fees,
incurred by him in any action, suit, or proceeding, whether
civil, criminal, administrative, or investigative, and whether
formal or informal, in which he is made or threatened to be made
a party by reason of being or having been in any such capacity,
or arising out of his status as such, except (i) in the case of
any action, suit, or proceeding terminated by judgment, order, or
conviction, in relation to matters as to which he is adjudged to
have breached or failed to perform the duties of his office and
the breach or failure to perform constituted willful misconduct
or recklessness; and (ii) in any other situation, in relation to
matters as to which it is found by a majority of a committee
composed of all directors not involved in the matter in
controversy (whether or not a quorum) that the person breached or
failed to perform the duties of his office and the breach or
failure to perform constituted willful misconduct or
recklessness.  Vectren 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 Vectren if it is ultimately determined that
the director or officer is not entitled to indemnification by
Vectren.

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

     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 proceedings 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.  A
determination must also be made that the facts then known to
those making the determination would not preclude
indemnification.  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.

     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 maintains directors' and officers' liability
insurance with an annual aggregate limit of $35,000,000 for the
current policy period, subject to a $500,000 deductible at the
corporate level, for each wrongful act where corporate
reimbursement is available to any director or officer.  Vectren
also maintains excess coverage with an aggregate annual limit of
$90,000,000. When corporate reimbursement is not available as
prescribed by applicable common law, statutory law or Vectren's
governing documents, the insurer will reimburse the directors and
officers with no deductible with respect to losses sustained by
them for specified wrongful acts while acting in their
capacities, individually or collectively, as such directors or
officers.

     Not applicable.

Item 9.  Undertakings.

     (a)  The undersigned registrant 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;

               (ii) To reflect in the prospectus any facts or events
     arising after the effective date hereof (or the most recent
     post-effective amendment hereof) which, individually or in
     the aggregate, represent a fundamental change in the
     information set forth in this registration statement;

               (iii)     To include any material information with
     respect to the plan of distribution not previously disclosed
     in this registration statement or any material change to
     such information in this registration statement;

provided, however, that the undertakings set forth in paragraphs
(i) and (ii) above do not apply if the information required to be
included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the registrant pursuant to
section 13 or section 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in this registration
statement.

     (2)  That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective
amendment 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.

     (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.

     (b)  The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of
1933, each filing of the registrant's annual report pursuant to
section 13(a) or section 15(d) of the Securities Exchange Act of
1934 (and each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Securities Exchange Act of 1934)
that is incorporated by reference in the 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.

     (c)  Insofar as indemnification for liabilities arising
under the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the registrant pursuant to
the foregoing provisions, 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 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 Act and will be governed by the final adjudication of such
issue.

                           SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933,
the registrant certifies that it has reasonable grounds to
believe that it meets all of the requirements for filing on Form
S-8 and has duly caused this registration statement to be signed
on its behalf by the undersigned thereunto duly authorized, in
the City of Evansville, State of Indiana, on March 30, 2000.
