                           ARTICLE II

                      CONVERSION OF SHARES

     Section 2.1    EFFECT OF MERGER ON CAPITAL STOCK.  At the
Effective Time, by virtue of the Merger and without any action on
the part of any holder of any capital stock of Indiana, SIGCORP or
the Company:

     (a)  CANCELLATION OF COMPANY CAPITAL STOCK.  Each share of the
capital stock of the Company issued and outstanding immediately
prior to the Effective Time shall be canceled and cease to exist,
and no consideration shall be delivered in exchange therefor.

     (b)  CANCELLATION OF CERTAIN COMMON STOCK.  Each share of
Common Stock, no par value, of  Indiana (the "INDIANA COMMON
STOCK") that is owned by  Indiana or any of its subsidiaries (as
defined in Section 4.1) or by SIGCORP or any of its subsidiaries
shall be canceled and cease to exist.  Each share of Common Stock,
no par value, of SIGCORP (the "SIGCORP COMMON STOCK") that is owned
by SIGCORP or any of its subsidiaries or by  Indiana or any of its
subsidiaries shall be canceled and cease to exist.

     (c)  CONVERSION OF CERTAIN COMMON STOCK.  Each issued and
outstanding share of  Indiana Common Stock (other than shares
canceled pursuant to Section 2.1(b)) shall be converted into the
right to receive 1.0 (the "INDIANA RATIO") duly authorized, validly
issued, fully paid and nonassessable shares of Common Stock, no par
value, of the Company (the "COMPANY COMMON STOCK"), and each issued
and outstanding share of SIGCORP Common Stock (other than shares
canceled pursuant to Section 2.1 (b)) shall be converted into the
right to receive 1.333 (the "SIGCORP RATIO") duly authorized,
validly issued, fully paid and nonassessable shares of Company
Common Stock.  Upon such conversions, all such shares of  Indiana
Common Stock and SIGCORP Common Stock shall be canceled and cease
to exist, and each holder of a certificate representing any such
shares shall cease to have any rights with respect thereto, except
the right to receive the number of whole shares of Company Common
Stock to be issued in consideration therefor and any cash in lieu
of fractional shares in accordance with Section 2.2.

     Section 2.2    EXCHANGE OF CERTIFICATES..

     (a)  DEPOSIT WITH EXCHANGE AGENT.  As soon as practicable
after the Effective Time, the Company shall deposit with a bank or
trust company mutually agreeable to  Indiana and SIGCORP (the
"EXCHANGE AGENT") certificates representing shares of Company
Common Stock required to effect the exchanges referred to in
Section 2.1, and shares that would be issued to the holders of
Indiana and SIGCORP Common Stock but for the provisions of Section
2.2(d).

     (b)  EXCHANGE PROCEDURES.  As soon as practicable after the
Effective Time, the Exchange Agent shall mail to each holder of
record of a certificate or certificates that, immediately prior to
the Effective Time, represented outstanding shares of  Indiana
Common Stock or SIGCORP Common Stock (collectively, the
"CERTIFICATES") that were converted (collectively, the "CONVERTED
SHARES") into the right to receive shares of Company Common Stock
(collectively, the "COMPANY SHARES") pursuant to Section 2.1, (i)
a form of letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to any Certificate
shall pass, only upon actual delivery of such Certificate to the
Exchange Agent) and (ii) instructions for use in effecting the
surrender of Certificates or affecting any necessary book-entry
transfers in the case of uncertificated shares of  Indiana Common
Stock or SIGCORP Common Stock in exchange for certificates
representing Company Shares.  Upon surrender of a Certificate to
the Exchange Agent (or to such other agent or agents as may be
appointed by agreement of  Indiana and SIGCORP) or evidence of any
necessary book-entry transfers in the case of uncertificated
shares, together with a duly executed letter of transmittal and
such other documents as the Exchange Agent shall require, the
holder of such Certificate or person on whose behalf such book-
entry transfer is made shall be entitled to receive in exchange
therefor a certificate representing the number of whole Company
Shares that such holder has the right to receive pursuant to the
provisions of this Section 2.1.  In the event of a transfer of
ownership of Converted Shares that is not registered in the
transfer records of  Indiana  or SIGCORP, as the case may be, a
certificate representing the proper number of Company Shares may be
issued to the transferee if the Certificate representing such
Converted Shares is presented to the Exchange Agent, accompanied by
all documents required to evidence and effect such transfer.  If
any Certificate shall have been lost, stolen, mislaid or destroyed,
then upon receipt of (x) an affidavit of that fact from the holder
claiming such Certificate to be lost, mislaid, stolen or destroyed,
(y) such bond, security or indemnity as the Company or the Exchange
Agent may reasonably require, and (z) any other documentation
necessary to evidence and effect the bona fide exchange thereof,
the Exchange Agent shall issue to such holder a certificate
representing the number of Company Shares into which the shares
represented by such lost, stolen, mislaid or destroyed Certificate
shall have been converted.  Until surrendered as contemplated by
this Section 2.2, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive
upon such surrender a certificate representing Company Common Stock
as contemplated by this Section 2.2.

     (c)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.     No
dividends or other distributions declared or made after the
Effective Time with respect to Company Shares with a record date
after the Effective Time shall be paid to the holder of any
unsurrendered Certificate with respect to the Company Shares
represented thereby, and no cash payment in lieu of fractional
shares shall be made to any such holder pursuant to Section 2.2(d),
until the holder of record of such Certificate shall surrender such
Certificate as contemplated by Section 2.3(b).  Subject to the
effect of unclaimed property, escheat and other applicable laws,
following surrender of any such Certificate there shall be paid the
holder of the certificates representing whole Company Shares issued
in exchange therefor, without interest, (i) at the time of such
surrender or as soon thereafter as may be practicable, the amount
of any cash payable in lieu of a fractional Company Share to which
such holder is entitled pursuant to Section 2.2(d) and the amount
of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole Company
Shares and (ii) at the appropriate payment date, the amount of
dividends or other distributions with a record date after the
Effective Time but prior to surrender and a payment date subsequent
to surrender payable with respect to such whole Company Shares.

     (d)  NO FRACTIONAL SECURITIES.

               (i)  No certificates or scrip representing fractional
     Company Shares shall be issued upon the surrender for exchange
     of Certificates, and such fractional share interests will not
     entitle the owner thereof to vote or to any rights of a
     shareholder of Company Shares.

               (ii) As promptly as practicable following the Effective
     Time, the Exchange Agent shall determine the excess of (x) the
     number of full shares of Company Common Stock delivered to the
     Exchange Agent by the Company pursuant to Section 2.2(a) over
     (y) the aggregate number of  whole shares of Company Common
     Stock to be issued pursuant to Section 2.1, such excess being
     herein called the "EXCESS SHARES."  As soon after the
     Effective Time as practicable, the Exchange Agent, as agent
     for the holders of  Indiana  and SIGCORP Common Stock, shall
     sell the Excess Shares at then prevailing prices on the New
     York Stock Exchange, Inc. ("NYSE"), all in the manner provided
     in paragraph (iii) of this Section 2.2(d).

               (iii)     The sale of the Excess Shares by the Exchange
     Agent shall be executed on the NYSE through one or more member
     firms of the NYSE and shall be executed in round lots to the
     extent practicable.  Until the net proceeds of such sale or
     sales have been distributed to the holders of Indiana and
     SIGCORP Common Stock, the Exchange Agent shall hold such
     proceeds in trust for the holders of Indiana and SIGCORP
     Common Stock (the "COMMON SHARES TRUST").  The company shall
     pay all commissions, transfer taxes and other out-of-pocket
     transfer taxes and other out-of-pocket transaction costs,
     including the expenses and compensation, of the Exchange Agent
     incurred in connection with such sale of the Excess Shares.
     The Exchange Agent shall determine the portion of the Common
     Shares Trust to which each holder of Indiana and SIGCORP
     Common Stock is entitled.

               (iv) As soon as practicable after the determination of
     the amount of cash, if any, to be paid to holders of Indiana
     and SIGCORP Common Stock in lieu of any fractional share
     interests, the Exchange Agent shall distribute such amounts to
     such holders of Indiana and SIGCORP Common Stock in accordance
     with this Section 2.2.

     (e)  CLOSING OF TRANSFER BOOKS.  From and after the Effective
Time, the stock transfer books of Indiana and SIGCORP shall be
closed and no further registration of transfers of shares of
Indiana and SIGCORP Common Stock shall thereafter be made.  If
after the Effective Time Certificates are presented to the Company
for registration or transfer, they shall be canceled and exchanged
for certificates representing the number of whole Company Shares
and the cash amount, if any, determined in accordance with this
Article II.

     (f)  TERMINATION OF DUTIES OF EXCHANGE AGENT.  Any
certificates representing Company Shares deposited with the
Exchange Agent pursuant to Section 2.2(a) and not exchanged within
one year after the Effective Time pursuant to this Section 2.2
shall be returned by the Exchange Agent to the Company, which shall
thereafter act as Exchange Agent.  All funds held by the Exchange
Agent which are unclaimed at the end of one year from the Effective
Time shall be returned to the Company whereupon any holder of
unsurrendered Certificates shall look as a general unsecured
creditor only to the Company for payment of any funds to which such
holder may be entitled, subject to applicable law.  The Company
shall not be liable to any person for such shares or funds
delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.

                           ARTICLE III

                           THE CLOSING

     Section 3.1    CLOSING.    The closing of the Merger (the
"CLOSING") shall take place at the offices of Sommer & Barnard,
4000 Bank One Tower, 111 Monument Circle, Indianapolis, Indiana
46204 at 10:00 A.M., local time, on the second business day
immediately following the date on which the last of the conditions
set forth in Article VIII is fulfilled or waived (or, if such
second business day immediately falls on a record date for the
payment of dividends on the SIGCORP or Indiana Common Stock, on the
first business day thereafter that is not such a record date), or
at such other time, date and place as SIGCORP and Indiana shall
mutually agree (the "CLOSING DATE").

     Section 4.10   EMPLOYEE MATTERS:  ERISA.

     (a)  BENEFIT PLANS.  Section 4.10(a) of the SIGCORP Disclosure
Schedule contains a true and complete list of each material
employee benefit plan, program or arrangement, including, but not
limited to, any employee benefit plan within the meaning of Section
3(3) of ERISA and any vacation, severance, change-in-control, stock
purchase or stock option plan, program or arrangement maintained or
contributed to by SIGCORP, any of the SIGCORP Subsidiaries or any
other entity which would be treated under Section 414 of the Code
as a single employer with SIGCORP (collectively, with SIGCORP
Subsidiaries, a "SIGCORP COMMONLY CONTROLLED ENTITY") for the
benefit of any current or former employee, officer or director or
their dependents or beneficiaries (collectively, the "SIGCORP
PLANS") and each employment, consulting, severance, change-in-
control, termination, compensation, collective bargaining or
indemnification agreement, arrangement or understanding between
SIGCORP or any of the SIGCORP Commonly Controlled Entities (or by
which they are bound) and any current or former employee, officer
or director of SIGCORP or any of the SIGCORP Subsidiaries
(collectively, the "SIGCORP EMPLOYMENT ARRANGEMENTS").

     (b)  Except as set forth in the SIGCORP SEC Reports or in
Section 4.10(b) of the SIGCORP Disclosure Schedule and except as
could not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect:

               (i)  QUALIFICATION; COMPLIANCE.  Each SIGCORP Plan intended to
          be qualified under Section 401(a) of the Code has
          received a favorable determination letter from the IRS
          that it is so qualified.  Each SIGCORP Plan and each
          SIGCORP Employment Arrangement has been operated in all
          respects in accordance with its terms and the
          requirements of applicable laws, rules and regulations.
          There are no pending or, to the knowledge of SIGCORP,
          threatened or anticipated claims under or with respect to
          any SIGCORP Plan or SIGCORP Employment Arrangement by or
          on behalf of any current employee, officer or director,
          or dependent or beneficiary thereof, or otherwise (other
          than routine claims for benefits);

               (ii) LIABILITIES.  Neither SIGCORP nor any of the SIGCORP
          Commonly Controlled Entities has incurred any direct or
          indirect liability under, arising out of or by operation
          of the Code, Title IV of ERISA, or any other applicable
          law (other than for premium payments and contributions in
          the ordinary course of business), and no fact or event
          exists that could reasonably be expected to give rise to
          such liability.

                    (iii)     PAYMENTS RESULTING FROM THE MERGER.  No SIGCORP
               Plan or SIGCORP Employment Arrangement exists which
               could result in the payment to any current, former
               or future director, officer or employee of SIGCORP,
               any SIGCORP Commonly Controlled Entity or to any
               trustee under any "rabbi trust" or similar
               arrangement of any money or other property or
               rights or accelerate, vest or provide any other
               rights or benefits to or in any such employee or
               director as a result of the consummation,
               announcement of or other action relating to the
               transactions contemplated by this Agreement,
               whether or not such payment, acceleration, vesting
               or provision would constitute a "parachute payment"
               (within the meaning of Section 280G of the Code) or
               whether or not some other subsequent action or
               event would be required to cause such payment,
               acceleration, vesting or provision to be triggered.

               (iv) LABOR AGREEMENTS.  Neither SIGCORP nor any of the SIGCORP
          Subsidiaries is a party to any collective bargaining
          agreements.  Since January 1, 1995, neither  SIGCORP nor
          any of the SIGCORP Subsidiaries has had any employee
          strikes, work stoppages, slowdowns or lockouts or
          received any requests for collective bargaining.  There
          is no unfair labor practice, employment discrimination or
          other complaint against  SIGCORP or any of the SIGCORP
          Subsidiaries pending or, to the best knowledge of
          SIGCORP, threatened.

     SIGCORP Disclosure Schedule, each of  SIGCORP and each of its
     subsidiaries is in compliance with all applicable
     Environmental Laws (as hereinafter defined), except where the
     failure to be so in compliance would not reasonably be likely
     to have a SIGCORP Material Adverse Effect.

               (ii) Except as set forth in Section 4.11(a) of the
     SIGCORP Disclosure Schedule, neither SIGCORP nor any of its
     subsidiaries has received any written communication from any
     person or Governmental Authority that alleges that SIGCORP or
     any of its subsidiaries is not in compliance with applicable
     Environmental Laws, except where the failure to be so in
     compliance would not reasonably be likely to have a SIGCORP
     Material Adverse Effect.

     (b)  ENVIRONMENTAL PERMITS.  Except as set forth in Section
4.11(b) of the SIGCORP Disclosure Schedule, SIGCORP and each of its
subsidiaries has obtained or applied for all environmental, health

timely filed and is pending agency approval, and SIGCORP and its
subsidiaries are in compliance with all terms and conditions of all
such Environmental Permits and are not required to make any
expenditure in order to obtain or renew any Environmental Permits,
except where the failure to obtain or be in such compliance and the
requirement to make such expenditures would not reasonably be
likely to have a SIGCORP Material Adverse Effect.

     (c)  ENVIRONMENTAL CLAIMS.  Except as set forth in Section
4.11(c) of the SIGCORP Disclosure Schedule, there is no
Environmental Claim (as hereinafter defined) pending, or to the
knowledge of SIGCORP and its subsidiaries, threatened

     operations that SIGCORP or any of its subsidiaries or joint
     ventures owns, leases or manages, in whole or in part,

that, if adversely determined, would reasonably be likely to have
a SIGCORP Material Adverse Effect.

     (d)  RELEASES.  Except as set forth in Section 4.11(c) or
4.11(d) of the SIGCORP Disclosure Schedule, SIGCORP has no
knowledge of any Release (as hereinafter defined) of any Hazardous
Material (as hereinafter defined) that would be reasonably likely
to form the basis of any Environmental Claim against SIGCORP or any
subsidiaries or joint ventures of SIGCORP, or against any person or
entity whose liability for any Environmental Claim SIGCORP or any
subsidiaries or joint ventures of SIGCORP has or may have retained
or assumed either contractually or by operation of law, except for
Releases of Hazardous Materials the liability for which would not
reasonably be likely to have a SIGCORP Material Adverse Effect.

     (e)  PREDECESSORS.  Except as set forth in Section 4.11(c) of
the SIGCORP Disclosure Schedule, SIGCORP has no knowledge, with
respect to any predecessor of SIGCORP or any subsidiary or joint
venture of SIGCORP, of any Environmental Claims pending or
threatened, or of any Release of Hazardous Materials that would be
reasonably likely to form the basis of any Environmental Claims
that would have, or that SIGCORP reasonably believes would be
reasonably likely to have, a SIGCORP Material Adverse Effect.

     (f)  DISCLOSURE.  To SIGCORP's knowledge, SIGCORP has
disclosed to Indiana all material facts that SIGCORP reasonably
believes form the basis of a SIGCORP Material Adverse Effect
arising from:

     required or known to be required in the future;

               (ii) current remediation costs or remediation costs known
     to be required in the future; or

               (iii)     any other environmental matter affecting
     SIGCORP or its subsidiaries that would have, or that SIGCORP
     reasonably believes would reasonably be likely to have, a
     SIGCORP Material Adverse Effect.

refrain from taking any action that a majority of such Board
determines in good faith, based upon the written opinion of outside
counsel, would result in a breach of its fiduciary duties under
applicable law.  If any Distribution Date or Shares Acquisition
Date occurs under the SIGCORP Rights Agreement at any time during
the period from the date of this Agreement to the Effective Time,
SIGCORP and Indiana shall make such adjustment to the Indiana Ratio

the notes thereto for the year ended September 30, 1998, or that

Schedule contains a true and complete list of each material
employee benefit plan, program or arrangement, including, but not
limited to, any employee benefit plan within the meaning of Section
3(3) of ERISA and any vacation, severance, change-in-control, stock
purchase or stock option plan, program or arrangement maintained or
contributed to by Indiana, any of the Indiana Subsidiaries or any
other entity which would be treated under Section 414 of the Code
as a single employer with Indiana (collectively, with Indiana
Subsidiaries, an "INDIANA COMMONLY CONTROLLED ENTITY") for the
benefit of any current or former employee, officer or director or
their dependents or beneficiaries (collectively, the "INDIANA
PLANS") and each employment, consulting, severance, change-in-
control, termination, compensation, collective bargaining or
indemnification agreement, arrangement or understanding between
Indiana or any of the Indiana Commonly Controlled Entities (or by
which they are bound) and any current or former employee, officer
or director of Indiana or any of the Indiana Subsidiaries
(collectively, the "INDIANA EMPLOYMENT ARRANGEMENTS").

     (b)  Except as set forth in the Indiana SEC Reports or in
Section 5.10(b) of the Indiana Disclosure Schedule and except as
could not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect:

               (i)  QUALIFICATION; COMPLIANCE.  Each Indiana Plan intended to
          be qualified under Section 401(a) of the Code has
          received a favorable determination letter from the IRS
          that it is so qualified.  Each Indiana Plan and each
          Indiana Employment Arrangement has been operated in all
          respects in accordance with its terms and the
          requirements of applicable laws, rules and regulations.
          There are no pending or, to the knowledge of Indiana,
          threatened or anticipated claims under or with respect to
          any Indiana Plan or Indiana Employment Arrangement by or
          on behalf of any current employee, officer or director,
          or dependent or beneficiary thereof, or otherwise (other
          than routine claims for benefits);

               (ii) LIABILITIES.  Neither Indiana nor any of the Indiana
          Commonly Controlled Entities has incurred any direct or
          indirect liability under, arising out of or by operation
          of the Code, Title IV of ERISA, or any other applicable
          law (other than for premium payments and contributions in
          the ordinary course of business), and no fact or event
          exists that could reasonably be expected to give rise to
          such liability.

                    (iii)     PAYMENTS RESULTING FROM THE MERGER.  No Indiana
               Plan or Indiana Employment Arrangement exists which
               could result in the payment to any current, former
               or future director, officer or employee of Indiana,
               any Indiana Commonly Controlled Entity or to any
               trustee under any "rabbi trust" or similar
               arrangement of any money or other property or
               rights or accelerate, vest or provide any other
               rights or benefits to or in any such employee or
               director as a result of the consummation,
               announcement of or other action relating to the
               transactions contemplated by this Agreement,
               whether or not such payment, acceleration, vesting
               or provision would constitute a "parachute payment"
               (within the meaning of Section 280G of the Code) or
               whether or not some other subsequent action or
               event would be required to cause such payment,
               acceleration, vesting or provision to be triggered.

               (iv) LABOR AGREEMENTS.  Neither Indiana nor any of the Indiana
          Subsidiaries is a party to any collective bargaining
          agreements.  Since January 1, 1995, neither Indiana nor
          any of the Indiana Subsidiaries has had any employee
          strikes, work stoppages, slowdowns or lockouts or
          received any requests for collective bargaining.  There
          is no unfair labor practice, employment discrimination or
          other complaint against Indiana or any of the Indiana
          Subsidiaries pending or, to the best knowledge of
          Indiana, threatened.

     (a)  COMPLIANCE.

               (i)  Except as set forth in Section 5.11(a) of the
     Indiana Disclosure Schedule, each of Indiana and each of its
     subsidiaries and joint ventures is and has been in compliance
     with all applicable Environmental Laws, except where the
     failure to be so in compliance would not reasonably be likely
     to have an Indiana Material Adverse Effect.

               (ii) Except as set forth in Section 5.11(a) of the
     Indiana Disclosure Schedule, neither Indiana nor any of its
     subsidiaries and joint ventures has received any written
     communication from any person or Governmental Authority that
     alleges that Indiana or any of its subsidiaries and Joint

     Effect.

     (b)  ENVIRONMENTAL PERMITS.  Except as set forth in Section
5.11(b) of the Indiana Disclosure Schedule, Indiana and each of its
subsidiaries and Joint ventures has obtained or has applied for all

facilities and the conduct of their operations, and all such
permits are in good standing or, where applicable, a renewal
application has been timely filed and is pending agency approval,
and Indiana and its subsidiaries and Joint ventures are in
compliance with all terms and conditions of all such Environmental
Permits and are not required to make any expenditure in order to
obtain or renew any Environmental Permits, except where the failure
to obtain or be in such compliance and the requirement to make such
expenditures would not reasonably be likely to have an Indiana
Material Adverse Effect.

     (c)  ENVIRONMENTAL CLAIMS.  Except as set forth in Section
5.11(c) of the Indiana Disclosure Schedule, there is no
Environmental Claim pending, or to the knowledge of Indiana and its
subsidiaries, threatened:

               (i)  against Indiana or any of its subsidiaries or joint
     ventures;

               (ii) against any person or entity whose liability for any
     Environmental Claim Indiana or any of its subsidiaries or
     joint ventures has or may have retained or assumed either
     contractually or by operation of law; or

               (iii)     against any real or personal property or
     operations that Indiana or any of its subsidiaries or joint
     ventures owns, leases or manages, in whole or in part;

that, if adversely determined, would reasonably be likely to have
an Indiana Material Adverse Effect.

     (d)  RELEASES.  Except as set forth in Section 5.11(c) or
5.11(d) of the Indiana Disclosure Schedule, Indiana has no
knowledge of any Release of any Hazardous Material that would be
reasonably likely to form the basis of any Environmental Claim
against Indiana or any of its subsidiaries or joint ventures of
Indiana, or against any person or entity whose liability for any
Environmental Claim Indiana or any subsidiaries or joint ventures
of Indiana has or may have retained or assumed either contractually
or by operation of law, except for Releases of Hazardous Materials
the liability for which would not reasonably be likely to have an
Indiana Material Adverse Effect.

     (e)  PREDECESSORS.  Except as set forth in Section 5.11(e) of
the Indiana Disclosure Schedule, Indiana has no knowledge, with
respect to any predecessor of Indiana or any subsidiary or joint
venture of Indiana, of any Environmental Claims pending or
threatened, or of any Release of Hazardous Materials that would be
reasonably likely to form the basis of any Environmental Claims
that would have, or that Indiana reasonably believes would
reasonably be likely to have an Indiana Material Adverse Effect.

     (f)  DISCLOSURE.  To Indiana's knowledge, Indiana has
disclosed to SIGCORP all material facts that Indiana reasonably
believes form the basis of an Indiana Material Adverse Effect
arising from:

               (i)  the cost of pollution control equipment currently
     required or known to be required in the future;

               (ii) current remediation costs or remediation costs known
     to be required in the future; or

               (iii)     any other environmental matter affecting
     Indiana or its subsidiaries that would have, or that Indiana

     Indiana Material Adverse Effect.

the 1935 Act exempt from all provisions of the 1935 Act except

     Section 5.14   ACCOUNTING MATTERS.  Indiana has not, through
the date hereof, in contemplation of the Merger, taken or agreed to
take any action that would prevent the Company from accounting for
the business combination to be effected by the Merger as a pooling-

regulations.

     Section 5.15   APPLICABILITY OF CERTAIN INDIANA LAW.

     (a)  Assuming the accuracy of the representation by SIGCORP
set forth in Section 4.18, neither the control share acquisition
provisions of Chapter 40 of the IBCL nor the business combination
provisions of Chapter 41 of the IBCL or any similar provisions of
the IBCL, the Articles of Incorporation or Bylaws of Indiana are
applicable to the transactions contemplated by this Agreement or
the Indiana Option.

     (b)  Indiana shall take all action requested in writing by
SIGCORP to render the rights granted to the holders of Indiana
Common Stock (the "INDIANA RIGHTS") pursuant to the Rights
Agreement dated as of July 30, 1986 between Indiana and First

"Indiana Rights Agreement"), inapplicable to the Merger and the
other transactions contemplated by this Agreement and the Indiana
Option.  Except as approved in writing by SIGCORP, the Board of
Indiana shall not (i) amend the Indiana Rights Agreement, (ii)
redeem the Indiana Rights, or (iii) take action with respect to, or
make any determination under, the Indiana Rights Agreement,
provided, that nothing contained in this Section 5.15(b) shall
require the Board of Directors of Indiana to take any action or
refrain from taking any action that a majority of such Board
determines in good faith, based upon the written opinion of outside
counsel, would result in a breach of its fiduciary duties under
applicable law.  If any Distribution Date or Shares Distribution
Date occurs under the Indiana Rights Agreement at any time during
the period from the date of this Agreement to the Effective Time,
Indiana and SIGCORP shall make such adjustment to the SIGCORP Ratio
as Indiana and SIGCORP shall mutually agree so as to preserve the
economic benefits that Indiana and SIGCORP each reasonably expected
on the date of this Agreement to receive as a result of the
consummation of the Merger and the other transactions contemplated
by this Agreement.

current or former employee, or current or former director of the
parties hereto or any of their subsidiaries; provided, however,
that this undertaking is not intended to prevent the Company from
enforcing such contracts, agreements, collective bargaining
agreements and commitments in accordance with their terms,
including any reserved right to amend, modify, suspend, revoke or
terminate any such contract, agreement, collective bargaining
agreement or commitment.

     (b)  Each of SIGCORP and Indiana shall promptly furnish to the
other, upon reasonable request by the other, detailed information,
together with underlying documentation, with respect to all
existing or proposed individual employment or severance agreements
or amendments thereto.

     Section 7.10   INCENTIVE, STOCK AND OTHER PLANS.

     With respect to each of the plans and programs of SIGCORP and
Indiana identified in Section 6.3 of the SIGCORP and Indiana
Disclosure Schedules that the parties later determine shall survive
the Closing and each other employee benefit plan, program or
arrangement of the Company under which the delivery of SIGCORP
Common Stock, Indiana Common Stock or Company Common Stock, as the
case may be, is required to be used for purposes of the payment of
benefits, grant of awards or exercise of options (each a "STOCK
PLAN"),

               (i)  Indiana and SIGCORP shall take such action as may be
     necessary so that, after the Effective Time, such Stock Plan
     shall provide for the issuance only of Company Common Stock
     such that:

                                   (A)  with respect to options to purchase
               SIGCORP Common Stock ("SIGCORP STOCK OPTION"), the
               number of shares of Company Common Stock
               purchasable upon exercise of such SIGCORP Stock
               Option shall be equal to that number of shares of
               Company Common Stock determined by multiplying the
               number of shares of SIGCORP Common Stock subject to
               such SIGCORP Stock Option by the SIGCORP Ratio,
               rounded, if necessary, to the nearest whole share
               of Company Common Stock, at a price per share
               (rounded to the nearest one-hundredth of a cent)
               equal to the per share exercise price specified in
               such SIGCORP Stock Option divided by the SIGCORP
               Ratio; provided, however, that in the case of any
               SIGCORP Stock Option to which Section 421 of the
               Code applies by reason of its qualification under
               Section 422 of the Code, the option price, the
               number of shares subject to such option and the
               terms and conditions of exercise of such option
               shall be determined in a manner consistent with the
               requirements of Section 424(a) of the Code; and

                                  (B)  with respect to any restricted stock plan
               of Indiana (the "INDIANA RESTRICTED STOCK PLANS"),
               Indiana and the Company shall take such actions as
               may be necessary so that, at the Effective Time,
               all restrictions on any restricted stock granted
               pursuant to the Indiana Restricted Stock Plans
               shall lapse on the date immediately prior to the
               Effective Time; provided, further, that upon the
               Effective Time, all shares of stock issued pursuant
               to the Indiana Restricted Stock Plans shall be
               treated in accordance with Section 2.1 herein.

               (ii) The Company shall:

                                   (A)  take all corporate action necessary or
               appropriate to obtain shareholder approval with
               respect to such Stock Plan to the extent such
               approval is required for purposes of the Code or
               other applicable law or stock exchange regulation,
               or, to the extent the Company deems it desirable,
               to enable such Stock Plan to comply with Rule 16b-3
               promulgated under the Exchange Act;

                                   (B)  reserve for issuance under such Stock
               Plan or otherwise provide a sufficient number of
               shares of Company Common Stock for delivery upon
               payment of benefits, grants of awards or exercise
               of options under such Stock Plan; and

                                   (C)  as soon as practicable after the
               Effective Time, file one or more registration
               statements under the Securities Act with respect to
               the shares of Company Common Stock subject to such
               Stock Plan to the extent such filing is required
               under applicable law and use its best efforts to
               maintain the effectiveness of such registration
               statement(s)  (and the current status of the
               prospectuses contained therein or related thereto)
               so long as such benefits, grants or awards remain
               payable or such options remain outstanding, as the
               case may be.

     Section 7.11   EMPLOYEE BENEFIT PLANS.  Each of the Indiana
Plans and SIGCORP Plans and Indiana Employment Arrangements and
SIGCORP Employment Arrangements, in effect on the date hereof (or
as amended or established in accordance with or as permitted by
this Agreement) shall be maintained in effect (except as otherwise
provided in Section 7.14), with respect to the employees, former
employees, directors or former directors of Indiana and any of its
subsidiaries and of SIGCORP and any of its subsidiaries,
respectively, who are covered by such plans or arrangements
immediately prior to the Effective Time until the Company
determines otherwise on or after the Effective Time and the Company
shall assume as of the Effective Time each SIGCORP Plan and Indiana
Plan or SIGCORP Employment Arrangement maintained by SIGCORP
immediately prior to the Effective Time and Indiana Employment
Arrangement maintained by Indiana immediately prior to the
Effective Time  and perform such plan or arrangement in the same
manner and to the same extent that SIGCORP and Indiana would,
respectively, be required to perform thereunder; provided, however,
that nothing herein contained, other than the provisions of Section
6.9, shall limit any reserved right contained in any such Indiana
Benefit Plan or Indiana Employment Arrangement or SIGCORP Benefit
Plan or SIGCORP Employment Arrangement to amend, modify, suspend,
revoke or terminate any such plan or arrangement.  Without limiting
the foregoing, each participant in any Indiana Benefit Plan or
SIGCORP Benefit Plan shall receive credit for purposes of
eligibility to participate, vesting and eligibility to receive
benefits under any benefit plan of the Company or any of its
subsidiaries or affiliates for service credited for the
corresponding purpose under any such benefit plan; provided,
however, that such crediting of service shall not operate to cause
any such plan or arrangement to fail to comply with the applicable
provisions of the Code and ERISA.  Indiana and SIGCORP will
cooperate on and after the date hereof to develop appropriate
employee benefit plans, programs and arrangements, including but
not limited to, executive and incentive compensation, stock option
and supplemental executive retirement plans, for employees and
directors of the Surviving Company and its subsidiaries from and
after the Effective Time.  However, no provision contained in this
Section 7.11 shall be deemed to constitute an employment contract
between the Company  and any individual, or a waiver of the
Company's right to discharge any employee at any time, with or
without cause.


     Section 7.12   NO SOLICITATIONS.

     (a)  No party hereto shall, and each such party shall cause
its subsidiaries not to, permit any of its Representatives to, and
shall use its best efforts to cause such persons not to, directly
or indirectly, initiate, solicit or encourage, or take any action
to facilitate the making of any offer or proposal that constitutes
or is reasonably likely to lead to any Takeover Proposal (as
defined below), or, in the event of any unsolicited Takeover
Proposal, engage in negotiations, discussions or provide any
confidential information or data to any person relating to any
Takeover Proposal.

     (b) SIGCORP and Indiana shall notify the other orally and in
writing of any such inquiries, offers or proposals (including,
without limitation, the terms and conditions of any such proposal
and the identity of the person making it) within 24 hours of the
receipt thereof and shall give the other ten days' advance notice
of any agreement to be entered into with or any information to be
supplied to any person making such inquiry, offer or proposal.

     (c)  Each party hereto shall immediately cease and cause to be
terminated all existing discussions and negotiations, if any, with
any other persons conducted heretofore with respect to any Takeover
Proposal.

     (d)  Notwithstanding anything in this Section 7.12 to the
contrary, unless the Indiana Shareholders' Approvals or the SIGCORP
Shareholders' Approvals, as the case may be, have been obtained,
Indiana or SIGCORP may, subject to (b) above, to the extent that a
majority of the Board of Directors of such party determines in good
faith on the basis of the written opinion of outside counsel that
a failure to do so would result in a breach of its fiduciary duties
under applicable law, participate in discussions or negotiations
with, furnish information to, and afford access to the properties,
books and records of such party and its subsidiaries to any person
in connection with a written bona fide Takeover Proposal with
respect to such party by such person.  Prior to providing any
information or data to any person in connection with a Takeover
Proposal by such person, the Indiana Board of Directors or the
SIGCORP Board of Directors as the case may be, shall receive from
such person an executed confidentiality agreement containing
customary terms and provisions.

     (e)  As used in this Section 7.12, "TAKEOVER PROPOSAL" shall
mean any tender or exchange offer, proposal for a merger,
reorganization, share exchange, recapitalization, consolidation or
other business combination involving SIGCORP, Indiana or any of
their respective material subsidiaries, or any proposal or offer to
acquire in any manner an equity interest of 10% or more in, or a
significant portion of the assets of, SIGCORP, Indiana or any of
their respective material subsidiaries, other than pursuant to the
transactions contemplated by this Agreement.

     Section 7.13   COMPANY BOARD OF DIRECTORS.

     Indiana Energy's and SIGCORP's Boards of Directors shall take
such action as may be necessary to cause the number of directors
comprising the full Board of Directors of the Company (the "COMPANY
BOARD") at the Effective Time to be 16 persons, consisting of 8
persons designated by Indiana prior to the Effective Time and 8
persons designated by SIGCORP prior to the Effective Time;
provided, however, that if, prior to the Effective Time, any of
such designees shall decline or be unable to serve, the party that
designated such person shall designate another person to serve in
such person's stead.  In the event one or more of the designees
dies, retires, resigns or otherwise becomes unable or unwilling to
serve within the first three years following the Effective Time,
the designees of the then majority may, to maintain the equal
allocation as nearly as practicable among SIGCORP and Indiana
designees, reduce their representation on the Company Board through
removal or resignation.  Such decision must be made as promptly as
practicable, and in no event later than the next meeting of the
Company Board members.   Should the majority fail to reduce the
number of designees serving on the Company Board, the minority may
designate a successor director who shall be elected to the Company
Board as soon as practicable.

     (a)  The initial designation of directors among the three
classes of the Company Board shall be allocated among SIGCORP and
Indiana designees.

     (b)  The initial Company Board committees and committee
memberships shall be determined by the Company Board; provided,
however that as nearly as practical an equal number of committees
shall be chaired by a designee of the SIGCORP Board; on the one
hand and by a designee of the Indiana Board on the other hand.
Each such committee shall have, as near as is practicable, an equal
number of members designated by SIGCORP and by Indiana.

     (c)  From the Effective Time until three years after the
Closing Date, a vote of sixty six and two thirds percent (66 2/3%)
of the members of the Company Board shall be required to approve a
change in the Company's name or the location of its headquarters or
principal executive offices, to amend the employment contracts
identified in Section 7.15 or otherwise change any of the titles or
functions of the particular individuals referred to in Section 7.14
as set forth in such employment contracts as in effect at the
Effective Time or to amend any bylaw provisions corresponding to
the provisions of this Section 7.13(d) adopted pursuant to Section
1.4.

     Section 7.14   COMPANY OFFICERS.

     (a)  From the Effective Time until the earlier of his
resignation or removal by the Company Board of Directors, Mr. Niel
C. Ellerbrook shall serve as Chairman of the Board and Chief
Executive Officer.  If Mr. Ellerbrook is not available at the
Effective Time to serve as Chief Executive Officer, then Indiana
shall designate a new Chief Executive Officer of the Company (the

     (b)  From the Effective Time until the earlier of his
resignation or removal by the Company Board of Directors, Mr.

Officer of the Company.  If Mr. Goebel is not available at the
Effective Time to serve as President and Chief Operating Officer of
the Company, then SIGCORP shall designate a new President and Chief
Operating Officer of the Company (the "REPLACEMENT COO"), subject
to the approval of Indiana.

     (c)  The provisions of this Section 7.14 are subject to the
fiduciary duties of the Company Board and to the specific terms of
the employment contracts referred to in Section 7.15, and the
duties and responsibilities attributable to the positions referred
to in this Section 7.14 shall be as set forth in such contracts.

     Section 7.15   EMPLOYMENT CONTRACTS.

     The Company shall, as of or prior to the Effective Time, use
its reasonable best efforts to enter into employment contracts
with the individuals set forth in Exhibit 7.15.

     Section 7.16   CORPORATE OFFICES AND NAME.

     As soon as reasonably possible after the Effective Time, the
corporate headquarters and principal executive offices of the
Company shall be located in Evansville, Indiana, and the Company
shall maintain significant operations in Indianapolis, Indiana.
The corporate headquarters and principal offices of Indiana Gas
Company, Inc. shall be located in Indianapolis, Indiana.

     Section 7.17   TRANSITION MANAGEMENT.

     (a)  As promptly as practicable after the date hereof, Indiana
and SIGCORP shall create special transition management task forces
(the "TASK FORCES") that shall comprise  representatives from each
of the primary business functions of each company and headed by Mr.
Niel C. Ellerbrook (or an individual designated by him) and Mr.
Andrew E. Goebel (or an individual designated by him).

exception to the restrictions set forth in Article VI shall be
effective only if set forth in a writing that describes in
reasonable detail the actions proposed to be taken and that is
signed by Mr. Ellerbrook (or his designee) or Mr. Goebel (or his
designee), as the case may be.

     (c)  After the date hereof and prior to the Effective Time,
Mr. Goebel shall be invited to attend meetings of Indiana's Board
of Directors and Mr. Ellerbrook shall be invited to attend meetings
of SIGCORP's Board of Directors as appropriate in consultation with

Agreement to their respective boards.  All such organizational
matters and appointment of officers shall be subject to final
approval by a majority of the members of the Board of Directors of
the Company.

     Section 7.18   EXPENSES.  Except as disclosed in Section 7.18

incurring such expenses, except that those expenses incurred in
connection with printing the Joint Proxy/Registration Statement, as
well as the filing fee relating thereto, shall be shared equally by
Indiana, on the one hand, and SIGCORP, on the other.

     Section 7.19   COVENANT TO SATISFY CONDITIONS.

and Indiana shall each use its commercially reasonable efforts to
take or cause to be taken all actions, and to do or cause to be
done all things, necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the Merger
and the other transactions contemplated hereby (subject to the

any court of competent jurisdiction in the United States or any
State shall have issued an order, judgment or decree permanently
restraining, enjoining or otherwise prohibiting the Merger, and
such order, judgment or decree shall have become final and
nonappealable;

     (e)  by SIGCORP, at any time prior to the SIGCORP
Shareholders' Approval, upon five days' prior notice to Indiana,

written offer or proposal with respect to a merger, sale of a
material portion of its assets, voting securities or other business
combination (each, a "BUSINESS COMBINATION"), in each case by a
party other than Indiana or any of its affiliates, a majority of
the Board of Directors of SIGCORP determines in good faith that the
fiduciary obligations of such directors under applicable law
require that such tender or exchange offer or other bona fide
written offer or proposal be accepted; provided, however, that:

               (i)  the Board of Directors of SIGCORP shall have
     received the written opinion of outside counsel to the effect
     that, notwithstanding a binding commitment to consummate an
     agreement of the nature of this Agreement entered into in the
     proper exercise of their applicable fiduciary duties, such
     fiduciary duties would also require the directors to
     reconsider such commitment as a result of such tender or
     exchange offer or such bona fide written offer or proposal;

               (ii) SIGCORP shall have complied with Section 7.12; and

     to, negotiate with Indiana to make such adjustments in the
     terms and conditions of this Agreement as would enable SIGCORP
     to proceed with the transactions contemplated herein;

     (f)  by Indiana, at any time prior to the Indiana

if, as a result of a tender or exchange offer or any bona fide
written offer or proposal with respect to a Business Combination,
in each case by a party other than SIGCORP or any of its
affiliates, a majority of the Board of Directors of Indiana
determines in good faith that the fiduciary obligations of such
directors under applicable law require that such tender or exchange
offer or other bona fide written offer or proposal be accepted;
provided, however, that:

               (i)  the Board of Directors of Indiana shall have
     received the written opinion of outside counsel to the effect
     that, notwithstanding a binding commitment to consummate an
     agreement of the nature of this Agreement entered into in the
     proper exercise of their applicable fiduciary duties, such
     fiduciary duties would also require the directors to
     reconsider such commitment as a result of such tender or
     exchange offer or such bona fide written offer or proposal;

               (ii) Indiana shall have complied with Section 7.12; and

               (iii)     prior to any such termination, Indiana shall,
     and shall cause its respective financial and legal advisors
     to, negotiate with SIGCORP to make such adjustments in the
     terms and conditions of this Agreement as would enable Indiana
     to proceed with the transactions contemplated herein;

     (g)  by SIGCORP, by written notice to Indiana, if:

               (i)  there shall have been any material breach of any
     material representation or warranty, or any material breach of
     any covenant or agreement, of Indiana hereunder, and such
     breach shall not have been remedied within thirty days after

     specifying the nature of such breach and requesting that it be
     remedied; or

               (ii) the Board of Directors of Indiana shall (A) withdraw
     or modify in any manner materially adverse to SIGCORP its
     approval or recommendation of this Agreement or the Merger,
     (B) fail to reaffirm such approval or recommendation upon
     SIGCORP's request, (C) approve or recommend a Business
     Combination, or (D) resolve to take any of the actions
     specified in clauses (A), (B) or (C); or

     (h)  by Indiana, by written notice to SIGCORP, if:

               (i)  there shall have been any material breach of any
     material representation or warranty, or any material breach of
     any covenant or agreement, of SIGCORP hereunder, and such

party if:

               (i)  a third party acquires securities representing
     greater than 25% of the voting power of the outstanding voting
     securities of such other party; or

               (ii) individuals who as of the date hereof constitute the
     board of directors of such other party (together with any new
     directors whose election by such board of directors or whose
     nomination for election by the stockholders of such party was
     approved by a vote of a majority of the directors of such
     party then still in office who are either directors as of the
     date hereof  or whose election or nomination for election was
     previously so approved) cease for any reason to constitute a
     majority of the board of directors of such party then in
     office.

     (j)  by SIGCORP or Indiana, by written notice to the other
party if on or before June 11, 2000 (or December 31, 2000 if the

     Agreement.

               and,

               (ii)  at the time of such termination (or, in the case of
     any termination following a Shareholder Disapproval, prior to
     the shareholder meeting at which such Shareholder Disapproval
     occurred), there shall have been a third-party tender or
     exchange offer for shares of, or a third-party offer or

     recommendation or whose voting stock has been acquired or
     whose board has changed, or who has failed to approve the
     Replacement CEO or the Replacement COO, as the case may be,
     the ("TARGET PARTY") or the affiliates thereof which, at the
     time of such termination (or of the meeting of the Target
     Party's shareholders, as the case may be) shall not have been
     (x) rejected by the Target Party and its Board of Directors
     and (y) withdrawn by the third-party; and

               (i)  The parties agree that the agreements contained in
     this Section 9.3 are an integral part of the transactions
     contemplated by this Agreement and constitute liquidated
     damages and not a penalty.

               (ii) If one party fails to promptly pay to the other any
     amounts due under this Section 9.3, such defaulting party
     shall pay the costs and expenses (including reasonable legal
     fees and expenses) in connection with any action, including

one or more series.  The Board of Directors of the Corporation
("Board") is vested with authority to determine and state the

voting rights, if any, of each such series by the adoption and
filing in accordance with the Act, before the issuance of any
shares of such series, of an amendment or amendments to these
Articles determining the terms of such series, which amendment need

entitled to receive the net assets of the Corporation upon
dissolution.  The holders of shares of Common Stock have the right,
voting separately by class, to cast one vote for each duly
authorized, issued and outstanding share of Common Stock held by
them upon each question or matter in respect of which, under the
Act, such holders are entitled to vote by class.  Such holders also
have the right to cast one vote for each duly authorized, issued
and outstanding share of Common Stock held by them upon each
question or matter submitted generally to the holders of shares of
the Corporation in respect of which, under the Act, voting by class
or by series is not required.

upon such terms and conditions as it may, from time to time with
respect to each class of stock, determine subject only to the
restrictions, limitations, conditions and requirements imposed by
the Act, other applicable laws and these Articles, as the same may,
from time to time, be amended, and (ii) the making by the
Corporation of share dividends and share splits, pro rata and
without consideration, in shares of the same class or series or in
shares of any other class or series without obtaining the
affirmative vote or the written consent of the holders of the
shares of the class or series in which the payment or distribution
is to be made.

     Section 4.5.   Acquisition of Shares.  The Board has authority
to authorize and direct the acquisition by the Corporation of the
issued and outstanding shares of Preferred Stock and Common Stock

considerations, from such sources and upon such terms and
conditions as it may, from time to time, determine, subject only to
the restrictions, limitations, conditions and requirements imposed
by the Act, other applicable laws and these Articles, as the same
may, from time to time, be amended.

Corporation is registered on the books of the Corporation as the
owner thereof, for all purposes, and shall not be bound to
recognize any equitable or other claim to, or interest in, such
share or right on the part of any other person, whether or not the

     Section 5.1.   Number.  The number of directors of the
Corporation shall not be less than one (1) nor more than sixteen
(16), as may be specified in the initial Code of By-Laws of the
Corporation ("By-Laws") or by amendment to the By-Laws. The Code of
By-Laws may provide for a classified board of directors.   The
number of initial directors of the Corporation shall be two (2).
Directors need not be shareholders of the Corporation.  Subject to
express limitations contained in these Articles, (i) the business
and affairs of the corporation shall be managed under the direction
of the Board, and (ii) the Board shall have full, exclusive and
absolute power, control and authority over any and all property of
the Corporation.  The Board may take any action as in its sole
judgment and discretion is necessary or appropriate to conduct the
business and affairs of the Corporation without any action by
shareholders of the Corporation, on behalf of the Corporation.

     Section 5.2.   Vacancies.  Except as may be expressly provided
by law, newly created directorships resulting from any increase in

resulting from death, resignation, retirement, disqualification,
removal from office or other cause shall be filled by a majority
vote of the directors then in office.

     Section 5.3.   Removal.  Subject to the rights, if any, of
holders of one or more classes or series of Preferred Stock to
elect one or more directors, any director, or the entire Board, may
be removed from office at any time, but only for cause and only by
the affirmative vote of the holders of at least 80% of the voting
power of all of the shares of the Corporation entitled to vote
generally in the election of directors, voting together as a single
class.

     Section 5.4.   Amendment, Repeal.  Notwithstanding anything
contained in these Articles of Incorporation to the contrary, the
affirmative vote of the holders of at least 80% of the voting power
of all of the shares of the Corporation entitled to vote generally
in the election of directors, voting together as a single class,
shall be required to alter, amend or repeal this Article 5.

                            ARTICLE 6
                   Meetings of the Shareholders

     Section 6.1.   Place of Meetings.  All meetings of share-

holders of the Corporation shall be held at such place, within or
without the State of Indiana, as may be specified in the respective
notices or waivers of notice thereof.

     Section 6.2.   Annual Meeting.  The annual meeting of share-

holders for the purpose of electing directors and transacting such
other business as may properly come before the meeting shall be set
each year by resolution of the Board.  Failure to hold the annual
meeting shall not work any forfeiture or a dissolution of the
Corporation or affect the validity of any corporate action.

     Section 6.3.   Special Meetings.  Special meetings of the
shareholders may be called by the Chief Executive Officer or by the
Board.

     Section 6.4.   Notice of Meetings and Waiver.  A written or
printed notice, stating the place, day and hour of the meeting, and
in case of a special meeting the purpose or purposes for which the
meeting is called, shall be delivered or mailed by the Secretary or
by the officers or persons calling the meeting, to each shareholder
of the Corporation at the time entitled to vote, at such address as
appears upon the records of the Corporation, no fewer than ten nor
more than sixty days before the date of the meeting.  Notice of any
such meeting may be waived in writing by any shareholder, before or
after the date and time stated in the notice, if the waiver is
delivered to the Corporation for inclusion in the minutes for
filing with the corporate records.  Attendance at a meeting, in
person or by proxy, waives objection to lack of notice or defective
notice of the meeting unless the shareholder at the beginning of
the meeting objects to holding the meeting or transacting the
business at the meeting.  Further, a shareholder's attendance at a
meeting waives objection to consideration of a particular matter at
the meeting that is not within the purpose or purposes described in
the meeting notice unless the shareholder objects to considering
the matter when it is presented.

     Section 6.5.   Voting at Meetings.

               Clause (a).    Voting Rights.  Except as otherwise
     provided by law or by the provisions of the Articles of
     Incorporation, every holder of Common Stock of the Corporation
     shall have the right at all meetings of the shareholders of
     the Corporation to one vote for each share of Common Stock
     standing in his name on the books of the Corporation.

               Clause (b).    Proxies.  A shareholder may vote, either
     in person or by proxy executed as provided by the Indiana
     Business Corporation Law by the shareholder or a duly
     authorized attorney-in-fact.  No proxy shall be valid after
     eleven (11) months, unless a shorter or longer time is
     expressly provided in the appointment form.

               Clause (c).    Quorum.  At any meeting of shareholders,
     a majority of the shares outstanding and entitled to vote on
     the business to be transacted at such meeting, represented in
     person or by proxy, shall constitute a quorum.

     Section 6.6.   Action by Shareholders Without Meeting.  Any
action required or permitted to be taken at any meeting of the
shareholders may be taken without a meeting if the action is taken
by all shareholders entitled to vote on the action and is evidenced
by one or more written consents describing the action taken, signed
by all shareholders entitled to vote on the action and delivered to
the Corporation for inclusion in the minutes for filing with the
Corporation's records.

     Section 6.7.   Participation in Meetings by Means of Con-

ference or Other Similar Communications Equipment.  Any shareholder
may participate in an annual or special meeting of the shareholders
by, or through the use of, any means of communication by which all
shareholders participating may simultaneously hear each other
during the meeting.  A shareholder participating in such a meeting
by this means is deemed to be present in person at the meeting.

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

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.
The Corporation 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 the Corporation if

The Corporation may, in the discretion of the Board, fully or
partially provide the same rights of indemnification and reimburse-

ment as hereinabove provided for directors and officers of the

agents of the Corporation or who are or were serving at the request
of the Corporation as employees or agents of another foreign or
domestic corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise whether or not for profit.

     Section 7.4.   Nonexclusive Provision.  The indemnification
authorized under this Article 7 is in addition to all rights to
indemnification granted by Chapter 37 of the Indiana Business
Corporation Law (IND. CODE Section 23-1-37, et seq.) and in no way limits
the indemnification provisions of such Chapter.

                   similar transaction which has the effect of
                   reducing the number of outstanding shares of the
                   Common Stock, unless the failure so to increase
                   such annual rate is approved by a majority of the
                   Continuing Directors; and

              assistance or any tax credits or other tax advantages
              provided by the Corporation, whether in anticipation of

shareholders may be called by the Chief Executive Officer or by the
Board.

Section 3.4.   Notice and Waiver. A written or printed notice,

any shareholder, before or after the date and time stated in the
notice, if the waiver is delivered to the Corporation for inclusion
in the minutes for filing with the corporate records.  Attendance
at a meeting, in person or by proxy, waives objection to lack of
notice or defective notice of the meeting unless the shareholder at
the beginning of the meeting objects to holding the meeting or
transacting the business at the meeting.  Further, a shareholder=s
attendance at a meeting waives objection to consideration of a
particular matter at the meeting that is not within the purpose or
purposes described in the meeting notice unless the shareholder
objects to considering the matter when it is presented.

Section 3.5.   Notice of Shareholder Business.  At any meeting
of the shareholders, only such business may be conducted as shall
have been properly brought before the meeting, and as shall have
been determined to be lawful and appropriate for consideration by
shareholders at the meeting.  To be properly brought before a
meeting, business must be (a) specified in the notice of meeting
given in accordance with Section 3.4, (b) otherwise properly
brought before the meeting by or at the direction of the board of
directors or the chief officer, or (c) otherwise properly brought
before the meeting by a shareholder.  For business to be properly
brought before a meeting by a shareholder pursuant to clause (c),
the shareholder must have given timely notice thereof in writing to
the Secretary of the Corporation.  To be timely, a shareholder=s
notice must be delivered to, or mailed and received at, the
principal office of the Corporation, not less than fifty days nor
more than ninety days prior to the meeting; provided, however, that
in the event that less than sixty days notice of the date of the
meeting is given to shareholders, notice by the shareholder to be
timely must be so received not later than the close of business on
the tenth day following the day on which such notice of the date of
the meeting was given.  A shareholder=s notice to the Secretary
shall set forth as to each matter the shareholder proposes to bring
before the meeting (a) a brief description of the business desired
to be brought before the meeting, (b) the name and address, as they
appear on the Corporation=s stock records, of the shareholder
proposing such business, (c) the class and number of shares of the
Corporation which are beneficially owned by the shareholder, and

at the meeting shall, if the facts warrant, determine and declare
to the meeting that business was not properly brought before the
meeting in accordance with the By-Laws, or that business was not
lawful or appropriate for consideration by shareholders at the
meeting, and if he should so determine, he shall so declare to the
meeting and any such business shall not be transacted.

Section 3.6.  Notice of Shareholder Nominees.  Nominations of

class and number of shares of the Corporation which are
beneficially owned by such person, (iv) any other information
relating to such person that is required to be disclosed in
solicitation of proxies for election of directors, or is otherwise
required, in each case pursuant to Regulation 14A under the
Securities Exchange Act of 1934, as amended (including, without
limitation, such person=s written consent to being named in the
proxy statement as a nominee and to serving as a director, if
elected), and (v) the qualifications of the nominee to serve as a
director of the Corporation.  No shareholder nomination shall be
effective unless made in accordance with the procedures set forth
in this Section 3.6.  The person presiding at the meeting shall, if
the facts warrant, determine and declare to the meeting that a
shareholder nomination was not made in accordance with the By-Laws,
and if he should so determine, he shall so declare to the meeting
and the defective nomination shall be disregarded.

the appointment form.

action required or permitted to be taken at any meeting of the
shareholders may be taken without a meeting if the action is taken
by all shareholders entitled to vote on the action and is evidenced
by one or more written consents describing the action taken, signed
by all shareholders entitled to vote on the action and delivered to
the Corporation for inclusion in the minutes for filing with the
Corporation=s records.

Section 3.9.   Participation in Meetings by Means of Con-

ference or Other Similar Communications Equipment.  Any shareholder
may participate in an annual or special meeting of the shareholders
by, or through the use of, any means of communication by which all
shareholders participating may simultaneously hear each other
during the meeting.  A shareholder participating in such a meeting
by this means is deemed to be present in person at the meeting.

meeting at which directors are elected.  Each director shall hold
office until his successor is elected and qualified.  Directors

immediately after the annual meeting of the shareholders at the
place established by resolution of the Board, for the purpose of
organization, election of officers, and consideration of any other

not establish a place for such meeting by resolution, the meeting
will be held at the place where the shareholders meeting was held.
No notice shall be necessary for the holding of this annual
meeting.  If such meeting is not held as above provided, the
election of officers may be had at any subsequent meeting of the
Board specifically called in the manner provided in Section 4.3 of
this Article.

Section 4.3.   Other Meetings.  Regular meetings of the Board
may be held as provide for in a Board resolution, without notice of
the date, time, place or purpose of the meeting.  Special meetings
of the Board may be held upon the call of the Chief Operating
Officer, or of any member of the Board, at any place within or
without the State of Indiana, upon forty-eight hours= notice,
specifying the time, place and general purposes of the meeting,
given to each director, either personally, by mailing, or by
facsimile.  Such notice may be waived in writing by any director,
before or after the date stated in the notice, if the waiver is
signed by the director and filed with the Corporation=s minutes or
records.  In addition, a director=s attendance at or participation
in a meeting waives any required notice of the meeting unless the
director at the beginning of the meeting (or promptly upon his
arrival) objects to holding the meeting or transacting business at
the meeting and does not thereafter vote for or assent to action
taken at the meeting.

Section 4.4.   Quorum.  At any meeting of the Board, the

action required or permitted to be taken at any meeting of the
Board, or any committee thereof, may be taken without a meeting if

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.
The Corporation 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 the Corporation if
it is ultimately determined that the director or officer is not
entitled to indemnification by the Corporation.

Corporation as employees or agents of another foreign or domestic
corporation, partnership, joint venture, trust, employee benefit
plan or other enterprise whether or not for profit.

(d)  Non-exclusive Provision.  The indemnification
authorized under this Section 7.2 is in addition to all rights to
indemnification granted by Chapter 37 of the Indiana Business
Corporation Law (IND. CODE '' 23-1-37, et seq.) and in no way limits
the indemnification provisions of such Chapter.

in office at the time of such vote shall be necessary to effect any
alteration, amendment or repeal of this Code of By-Laws.

SIGCORP, Inc.
N.W. Fourth Street
Evansville, IN 47741-001

Vectren Corporation
N.W. Fourth Street
Evansville, IN 47741-001

Ladies and Gentlemen:

     The undersigned has been advised that, as of the date
hereof, the undersigned may be deemed to be an "affiliate" of
Indiana Energy, Inc., an Indiana corporation (the "Company"), as
that term is defined for purposes of paragraphs (c) and (d) of
Rule 145 of the Rules and Regulations (the "Rules and
Regulations") of the Securities and Exchange Commission (the
"SEC") under the Securities Act of 1933, as amended (the
"Securities Act").

     Pursuant to the terms and subject to the conditions of that
certain Agreement and Plan of Merger by and among SIGCORP, Inc.,
an Indiana corporation ("SIGCORP"), Vectren Corporation, an
Indiana corporation whose capital stock is 50% owned by the
Company and 50% owned by SIGCORP ("Vectren") and the Company,
dated as of June 11, 1999 (the "Merger Agreement"), providing
for, among other things, the merger of the Company and SIGCORP
with and into Vectren (the "Merger"), the undersigned will be
entitled to receive shares of common stock, without par value
("Vectren Common Stock"), of Vectren in exchange for shares of
common stock, without par value ("Company Common Stock"), of the
Company owned by me at the effective time of the Merger (the
"Effective Time") as determined pursuant to the Merger Agreement.

     The undersigned understands that the Merger will be treated
for financial accounting purposes as a "pooling of  interests" in
accordance with generally accepted accounting principles




and that the staff of the SEC has issued certain guidelines that
should be followed to ensure the application of pooling of
interests accounting to the transaction.

     In consideration of the agreements contained herein,
SIGCORP's, Vectren's and the Company's reliance on this letter in
connection with the consummation of the Merger and for other good
and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the undersigned hereby represents,
warrants and agrees that the undersigned has not made and will
not make any sale, transfer or other disposition of (i) Company
Common Stock or SIGCORP Common Stock within the 30 day period
prior to the date of the consummation of the Merger or (ii)
Vectren Common Stock received by the undersigned pursuant to the
Merger or otherwise owned by the undersigned until after such
time as financial statements of Vectren that include at least 30
days of combined operations of the Company, SIGCORP and Vectren
after the Merger shall have been publicly reported, unless the
undersigned shall have delivered to Vectren, prior to any such
sale, transfer or other disposition, a written opinion from
Arthur Andersen LLP, independent public accountants for Vectren,
or a written no-action letter from the accounting staff of the
SEC, in either case in form and substance reasonably satisfactory
to Vectren, to the effect that such sale, transfer or other
disposition will not cause the Merger not to be treated as a
"pooling of interests" for financial accounting purposes in
accordance with generally accepted accounting principles and the
rules, regulations and interpretations of the SEC and (iii)
Vectren Common Stock received by the undersigned pursuant to the
Merger in violation of the Securities Act or the Rules and
Regulations.  The undersigned has been advised that the offering,
sale and delivery of the shares of Vectren Common Stock pursuant
to the Merger will have been registered with the SEC under the
Securities Act on a Registration Statement on Form S-4.  The
undersigned has also been advised, however, that since the
undersigned may be deemed to be an affiliate of the Company at
the time the Merger is submitted for a vote of the stockholders
of the Company, Vectren Common Stock received by the undersigned
pursuant to the Merger can be sold by the undersigned only (i)
pursuant  to an effective registration statement under the
Securities Act of 1933 (the "Securities Act"), (ii) in conformity
with the volume and other limitations of Rule 145 promulgated by
the SEC under the Securities Act, or (iii) in reliance upon an
exemption from registration that is available under the
Securities Act.

     The undersigned also understands that instructions will be
given to the transfer agent for Vectren Common Stock with respect
to Vectren Common Stock to be received by the undersigned
pursuant to the Merger and that there will be placed on the
certificates representing such shares of Vectren Common Stock, or
any substitutions therefor, a legend stating in substance as
follows:

               "These shares were issued in a transaction to which
     Rule 145 promulgated under the Securities Act of 1933
     applies.  These shares may only be transferred in accordance
     with the terms of such Rule and an Affiliate's Agreement
     between the original holder of such shares and Vectren, a
     copy of which agreement is on file at the principal offices
     of Vectren."




It is understood and agreed that the legend set forth above shall
be removed upon surrender of certificates bearing such legend by
delivery of substitute certificates without such legend if the
undersigned shall have delivered to Vectren an opinion of
counsel, in form and substance reasonably satisfactory to
Vectren, to the effect that (i) the sale or disposition of the
shares represented by the surrendered certificates may be
effected without registration of the offering, sale and delivery
of such shares under the Securities Act and (ii) the shares to be
so transferred may be publicly offered, sold and delivered by the
transferee thereof without compliance with the registration
provisions of the Securities Act.

     By its execution hereof, Vectren agrees that it will, as
long as the undersigned owns any Vectren Common Stock to be
received by the undersigned pursuant to the Merger, take all
reasonable efforts to make timely filings with the SEC of all
reports required to be filed by it pursuant to the Securities
Exchange Act of 1934, as amended, and will promptly furnish upon
written request of the undersigned a written statement confirming
that such reports have been so timely filed.

     If you are in agreement with the foregoing, please so
indicate by signing below and returning a copy of this letter to
the undersigned, at which time this letter shall become a binding
agreement between us.

                                     Very truly yours,


                                     By:

     1.   GRANT OF OPTIONS.  SIGCORP hereby grants Indiana an
irrevocable option (the "SIGCORP Option") to purchase up to
4,702,483 shares, subject to adjustment as provided in Section 11
(such shares being referred to herein as the "SIGCORP Shares"), of
common stock, without par value, of SIGCORP (the "SIGCORP Common
Stock") (being 19.9% of the number of shares of SIGCORP Common
Stock outstanding on the date hereof), together with the associated
purchase rights (the "SIGCORP Rights"), issued pursuant to the
SIGCORP Rights Agreement referred to in Section 5.15 of the Merger
Agreement (the "SIGCORP Rights Agreement"), in the manner set forth
below at a price (the "Exercise Price") per SIGCORP Share of
$29.70, payable at Indiana's option, (a) in cash or (b) subject to
the receipt of the approvals of any Governmental Authority required
for SIGCORP to acquire the Indiana Shares (as defined below) from
Indiana, and for Indiana to issue the Indiana Shares to SIGCORP,
which approvals SIGCORP and Indiana shall use their respective
reasonable best efforts to obtain, in shares of common stock,
without par value, of Indiana (the "INDIANA SHARES"), in either
case in accordance with Sections 3 and 4 hereof.  Notwithstanding
the foregoing, in no event shall the number of SIGCORP Shares for
which the SIGCORP Option is exercisable exceed 19.9% of the number
of issued and outstanding shares of SIGCORP Common Stock.  As used
herein, the "Fair Market Value" of any share shall be the average
of the daily closing sales price for such share on the New York
Stock Exchange (the "NYSE") during the five NYSE trading days prior
to the NYSE trading day preceding the date such Fair Market Value
is to be determined.

     2.   EXERCISE OF OPTION.   The SIGCORP Option may be exercised
by Indiana, in whole or in part, at any time or from time to time
after the Merger Agreement becomes terminable by Indiana under
circumstances which could entitle Indiana to termination fees under
either Section 9.3(a) of the Merger Agreement or Section 9.3(b) of
the Merger Agreement, provided that the events specified in Section
9.3(b)(ii) of the Merger Agreement shall have occurred (regardless
of whether the Merger Agreement is actually terminated or whether
there occurs a closing of any Business Combination involving a
SIGCORP Target Party or a closing by which a SIGCORP Target Party
becomes a subsidiary), any such event by which the Merger Agreement
becomes so terminable by Indiana being referred to herein as a
"Trigger Event."  SIGCORP shall notify Indiana promptly in writing
of the occurrence of any Trigger Event, it being understood that
the giving of such notice by SIGCORP shall not be a condition to
the right of Indiana to exercise the SIGCORP Option.  In the event
Indiana wishes to exercise the SIGCORP Option, Indiana shall
deliver to SIGCORP a written notice (an "Exercise Notice")
specifying the total number of SIGCORP Shares it wishes to
purchase.  If at the time of issuance of any SIGCORP Shares
pursuant to an exercise of all or part of the SIGCORP Option
hereunder, SIGCORP shall not have redeemed the SIGCORP Rights, or
shall have issued any similar securities, then each SIGCORP Share
issued pursuant to such exercise shall also represent SIGCORP
Rights or new rights with terms substantially the same as and at
least as favorable to Indiana as are provided under the SIGCORP
Rights Agreement or any similar agreement then in effect.  Each
closing of a purchase of SIGCORP Shares (a "Closing") shall occur
at a place, on a date and at a time designated by Indiana in an
Exercise Notice delivered at least two business days prior to the
date of the Closing.  The SIGCORP Option shall terminate upon the
earlier of:  (i) the Effective Time; (ii) the termination of the
Merger Agreement pursuant to Section 9.1 thereof (other than upon
or during the continuance of a Trigger Event); or (iii) 180 days
following any termination of the Merger Agreement upon or during
the continuance of a Trigger Event (or if, at the expiration of
such 180 day period the SIGCORP Option cannot be exercised by
reason of any applicable judgment, decree, order, law or
regulation, ten business days after such impediment to exercise
shall have been removed or shall have become final and not subject
to appeal, but in no event under this clause (iii) later than the
third anniversary of the date hereof).  Notwithstanding the
foregoing, the SIGCORP Option may not be exercised if Indiana is in
material breach of any of its material representations or
warranties, or in material breach of any of its covenants or
agreements, contained in this Agreement or in the Merger Agreement.
Upon the giving by Indiana to SIGCORP of the Exercise Notice and
the tender of the applicable aggregate Exercise Price, Indiana
shall be deemed to be the holder of record of the SIGCORP Shares
issuable upon such exercise, notwithstanding that the stock
transfer books of SIGCORP shall then be closed or that certificates
representing such SIGCORP Shares shall not then be actually
delivered to Indiana.

     3.   CONDITIONS TO CLOSING.  The obligation of SIGCORP to
issue the SIGCORP Shares to Indiana hereunder is subject to the
conditions, which (other than the conditions described in clauses
(i), (iii) and (iv) below) may be waived by SIGCORP in its sole
discretion, that (i) all waiting periods, if any, under the HSR
Act, applicable to the issuance of the SIGCORP Shares hereunder
shall have expired or have been terminated; (ii) the SIGCORP
Shares, and any Indiana Shares which are issued in payment of the
Exercise Price, shall have been approved for listing on the NYSE
upon official notice of issuance; (iii) all consents, approvals,
orders or authorizations of, or registrations, declarations or
filings with, any federal, state or local administrative agency or
commission or other federal, state or local Governmental Authority,
if any, required in connection with the issuance of the SIGCORP
Shares or the acquisition of such SIGCORP Shares by Indiana
hereunder shall have been obtained or made, as the case may be,
including, without limitation, the approval of, if applicable, the
issuance of Indiana Shares to SIGCORP and the acquisition by
SIGCORP of the Indiana Shares constituting the Exercise Price
hereunder and approval of the SEC under the 1935 Act of the
acquisition of the SIGCORP Shares by Indiana; and (iv) no
preliminary or permanent injunction or other order by any court of
competent jurisdiction prohibiting or otherwise restraining such
issuance shall be in effect.

     4.   CLOSING.  At any Closing, (a) SIGCORP will deliver to
Indiana or its designee a single certificate in definitive form
representing the number of the SIGCORP Shares designated by Indiana
in its Exercise Notice, such certificate to be registered in the
name of Indiana and to bear the legend set forth in Section 12 and
(b) Indiana will deliver to SIGCORP the aggregate Exercise Price
for the SIGCORP Shares so designated and being purchased by (i)
wire transfer of immediately available funds or certified check or
bank check or (ii) subject to the condition in Section 1(b), a
certificate or certificates representing the number of Indiana
Shares being issued by Indiana in consideration thereof, as the
case may be.  For the purposes of this Agreement, the number of
Indiana Shares to be delivered to SIGCORP shall be equal to the
quotient obtained by dividing (i) the product of (x) the number of
SIGCORP Shares with respect to which the SIGCORP Option is being
exercised and (y) the Exercise Price by (ii) the Fair Market Value
of the Indiana Shares at the date immediately preceding the date
the Exercise Notice is delivered to SIGCORP.  SIGCORP shall pay all
expenses, and any and all United States federal, state and local
taxes and other charges that may be payable in connection with the
preparation, issue and delivery of stock certificates under this
Section 4 in the name of Indiana or such of its designees as shall
have obtained appropriate regulatory approval.

     5.   REPRESENTATIONS AND WARRANTIES OF SIGCORP.  SIGCORP

Option in accordance with its terms, and at all times from the date
hereof through the expiration of the SIGCORP Option will have
reserved, 4,702,483 authorized and unissued SIGCORP Shares, such
amount being subject to adjustment as provided in Section 11, all
of which, upon their issuance and delivery in accordance with the
terms of this Agreement, will be validly issued, fully paid and
nonassessable, (f) upon delivery of the SIGCORP Shares to Indiana
upon the exercise of the SIGCORP Option in accordance with its
terms, Indiana will acquire the SIGCORP Shares free and clear of
all claims, liens, charges, encumbrances and security interests of

     7.   CERTAIN REPURCHASES.

     (a)  INDIANA PUT.  At the request of Indiana by written notice
at any time during which the SIGCORP Option is exercisable pursuant
to Section 2 (the "Repurchase Period"), SIGCORP (or any successor
entity thereof) shall repurchase from Indiana all or any portion of
the SIGCORP Option, at the price set forth in subparagraph (i)
below, or, at the request of Indiana by written notice at any time
prior to the later of (I) June 11, 2000 (provided that such date
shall be extended to December 31, 2000 under the circumstances
where the date after which either party may terminate the Merger
Agreement pursuant to Section 9.1(b) of the Merger Agreement has
been extended to December 31, 2000) or (II) 180 days following any
termination of the Merger Agreement upon or during the continuance
of the Trigger Event, SIGCORP (or any successor entity thereof)
shall repurchase from Indiana all or any portion of the SIGCORP
Shares purchased by Indiana pursuant to the SIGCORP Option, at the
price set forth in subparagraph (ii) below:

          (i)  the difference between (x) the "Market/Offer Price"
     for shares of      SIGCORP Common Stock as of the date Indiana
     gives notice of its intent to exercise its      rights under
     this Section 7 (defined as the higher of (A) the price per
     share offered as of      such date pursuant to any tender or
     exchange offer or other offer with respect to a      Business
     Combination which was made prior to such date and not
     terminated or      withdrawn as of such date (the "Offer
     Price") and (B) the Fair Market Value of SIGCORP      Common
     Stock as of such date (the "Market Price"))  and the (y)
     Exercise Price,      multiplied by the number of SIGCORP
     Shares purchasable pursuant to the SIGCORP      Option (or
     portion thereof with respect to which Indiana is exercising
     its rights under this      Section 7), but only if the
     Market/Offer Price is greater than the Exercise Price;

          (ii)  the product of (x) the sum of (A) the Exercise
     Price paid by Indiana per      SIGCORP Share acquired pursuant
     to the SIGCORP Option and (B) the difference      between the
     Market/Offer Price and the Exercise Price, but only if the
     Market/Offer Price      is greater than the Exercise Price,
     and (y) the number of SIGCORP Shares so to be      repurchased
     pursuant to this Section 7.  For purposes of this clause (ii),
     the Offer Price      shall be the highest price per share
     offered pursuant to a tender or exchange offer or other
     Business Combination offer during the Repurchase Period prior
     to the delivery by      Indiana of a notice of repurchase.

     (b)  REDELIVERY OF INDIANA SHARES.  If Indiana elected to
purchase SIGCORP Shares pursuant to the exercise of the SIGCORP
Option by the issuance and delivery of Indiana Shares, then SIGCORP
shall, if so requested by Indiana, in fulfillment of its obligation
pursuant to clause (A) of Section 7(a)(ii)(x) (that is, with
respect to the Exercise Price only and without limitation to its
obligation to pay additional consideration under clause (B) of
Section 7(a)(ii)(x)), redeliver the certificate for such Indiana
Shares to Indiana, free and clear of all liens, claims, damages,
charges and encumbrances of any kind or nature whatsoever;
provided, however, that if less than all of the SIGCORP Shares
purchased by Indiana pursuant to the SIGCORP Option are to be
repurchased pursuant to this Section 7, then Indiana shall issue to
SIGCORP a new certificate representing those Indiana Shares which
are not due to be redelivered to Indiana pursuant to this Section
7 as they constituted payment of the Exercise Price for the SIGCORP
Shares not being repurchased.

     (c)  PAYMENT AND REDELIVERY OF SIGCORP OPTION OR SHARES.  In
the event Indiana exercises its rights under this Section 7,
SIGCORP shall, within 10 business days thereafter, pay the required
amount to Indiana in immediately available funds and Indiana shall
surrender to SIGCORP the SIGCORP Option or the certificates
evidencing the SIGCORP Shares purchased by Indiana pursuant
thereto, and Indiana shall warrant that it owns the SIGCORP Option
or such shares and that the SIGCORP Option or such shares are then
free and clear of all liens, claims, damages, charges and
encumbrances of any kind or nature whatsoever.

     (d)  INDIANA CALL.  If Indiana has elected to purchase SIGCORP
Shares pursuant to the exercise of SIGCORP Option by the issuance
and delivery of Indiana Shares, notwithstanding that Indiana may no
longer hold any such SIGCORP Shares or that Indiana elects not to
exercise its other rights under this Section 7, Indiana may
require, at any time or from time to time prior to June 11, 2000
(provided that such date shall be extended to December 31, 2000
under the circumstances where the date after which either party may
terminate the Merger Agreement pursuant to Section 9.1(b) of the
Merger Agreement has been extended to December 31, 2000), SIGCORP
sell to Indiana any such Indiana Shares at the price attributed to
such Indiana Shares pursuant to Section 4 plus interest at the rate
to 7% per annum on such amount from the Closing Date relating to
the exchange of such Indiana Shares pursuant to Section 4 to the
closing date under this Section 7(d) less any dividends on such
Indiana Shares paid during such period or declared and payable to
stockholders of record on a date during such period.

     (e)  REPURCHASE PRICE REDUCED AT INDIANA'S OPTION.  In the
event the repurchase price specified in Section 7(a) would subject
the purchase price of the SIGCORP Option purchased by Indiana
pursuant to the SIGCORP Option to a vote of the shareholders of
SIGCORP pursuant to applicable law or SIGCORP's Restated Articles
of Incorporate, then Indiana may, at its election, reduce the
repurchase amount which would permit such repurchase without the
necessity for such a shareholder vote.

     8.   VOTING OF SHARES.  Following the date hereof and prior to
the fifth anniversary of the date hereof (the "Expiration Date"),
each party shall vote any shares of capital stock of the other
party acquired by such party pursuant to this Agreement
("Restricted Shares"), including any Indiana Shares issued pursuant
to Section 1(b) or otherwise beneficially owned (within the meaning
of Rule 13d-3 promulgated under the Securities Exchange Act of
1934, as amended the ("Exchange Act")) by such party on each matter
submitted to a vote of shareholders of such other party for and
against such matter in the same proportion as the vote of all other
shareholders of such other party are voted (whether by proxy or
otherwise) for and against such matter.

     9.   RESTRICTIONS ON TRANSFER.

     (a)  Restrictions on Transfer.  Prior to the Expiration Date,
neither party shall, directly or indirectly, by operation of law or
otherwise, sell, assign, pledge, or otherwise dispose of or
transfer any Restricted Shares beneficially owned by such party,
other than (i) pursuant to Section 7, or (ii) in accordance with
Section 9(b) or Section 10.

     (b)  Permitted Sales.  Following the termination of the Merger
Agreement, a party shall be permitted to sell any Restricted Shares
beneficially owned by it if such sale is made pursuant to a tender
or exchange offer that has been approved or recommended, or
otherwise determined to be fair to and in the best interests of the
shareholders of the other party, by a majority of the members of
the Board of Directors of such other party, which majority shall
include a majority of directors who were directors prior to the
announcement of such tender or exchange offer.

     10.  REGISTRATION RIGHTS.  Following the termination of the
Merger Agreement, each party hereto (a "Designated Holder") may by
written notice (the "Registration Notice") to the other party (the
"Registrant") request the Registrant to register under the
Securities Act all or any part of the Restricted Shares
beneficially owned by such Designated Holder (the "Registrable
Securities") pursuant to a bona fide firm commitment underwritten
public offering in which the Designated Holder and the underwriters
shall effect as wide a distribution of such Registrable Securities
as is reasonably practicable and shall use their best efforts to
prevent any person (including any Group (as used in Rule 13d-5
under the Exchange Act)) and its affiliates from purchasing through
such offering Restricted Shares representing more than 1% of the
outstanding shares of common stock of the Registrant on a fully
diluted basis (a "Permitted Offering").  The Registration Notice
shall include a certificate executed by the Designated Holder and
its proposed managing underwriter, which underwriter shall be an
investment banking firm of nationally recognized standing (the
"Manager"), stating that (i) they have a good faith intention to
commence promptly a Permitted Offering and (ii) the Manager in good
faith believes that, based on the then prevailing market
conditions, it will be able to sell the Registrable Securities at
a per share price equal to at least 80% of the then Fair Market
Value of such shares.  The Registrant (and/or any person designated
by the Registrant) shall thereupon have the option exercisable by
written notice delivered to the Designated Holder within 10
business days after the receipt of the Registration Notice,
irrevocably to agree to purchase all or any part of the Registrable
Securities proposed to be so sold for cash at a price (the "Option
Price") equal to the product of (i) the number of Registrable
Securities to be so purchased by the Registrant and (ii) the then
Fair Market Value of such shares.  Any such purchase of Registrable
Securities by the Registrant (or its designee) hereunder shall take
place at a closing to be held at the principal executive offices of
the Registrant or at the offices of its counsel at any reasonable
date and time designated by the Registrant and/or such designee in
such notice within 20 business days after delivery of such notice.
Any payment for the shares to be purchased shall be made by
delivery at the time of such closing of the Option Price in
immediately available funds.

     If the Registrant does not elect to exercise its option
pursuant to this Section 10 with respect to all Registrable
Securities, it shall use its best efforts to effect, as promptly as
practicable, the registration under the Securities Act of the
unpurchased Registrable Securities proposed to be so sold;
provided, however, that (i) neither party shall be entitled to more
than an aggregate of two effective registration statements
hereunder and (ii) the Registrant will not be required to file any
such registration statement during any period of time (not to
exceed 40 days after such request in the case of clause (A) below
or 90 days in the case of clauses (B) and (C) below) when (A) the
Registrant is in possession of material non-public information
which it reasonably believes would be detrimental to be disclosed
at such time and, in the opinion of counsel to the Registrant, such
information would have to be disclosed if a registration statement
were filed at that time; (B) the Registrant is required under the
Securities Act to include audited financial statements for any
period in such registration statement and such financial statements
are not yet available for inclusion in such registration statement;
or (C) the Registrant determines, in its reasonable judgment, that
such registration would interfere with any financing, acquisition
or other material transaction involving the Registrant or any of
its affiliates.  The Registrant shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant to
this Section 10 to be qualified for sale under the securities or
Blue-Sky laws of such jurisdictions as the Designated Holder may
reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however,
that the Registrant shall not be required to qualify to do business
in, or to consent to general service of process in, any
jurisdiction by reason of this provision.

     The registration rights set forth in this Section 10 are
subject to the condition that the Designated Holder shall provide
the Registrant with such information with respect to such holder's
Registrable Securities, the plans for the distribution thereof, and
such other information with respect to such holder as, in the
reasonable judgment of counsel for the Registrant, is necessary to
enable the Registrant to include in such registration statement all
material facts required to be disclosed with respect to a
registration thereunder.

     A registration effected under this Section 10 shall be
effected at the Registrant's expense, except for underwriting
discounts and commissions and the fees and the expenses of counsel
to the Designated Holder, and the Registrant shall provide to the
underwriters such documentation (including certificates, opinions
of counsel and "comfort" letters from auditors) as are customary in
connection with underwritten public offerings as such underwriters
may reasonably require.  In connection with any such registration,
the parties agree (i) to indemnify each other and the underwriters
in the customary manner, (ii) to enter into an underwriting
agreement in form and substance customary for transactions of such
type with the Manager and the other underwriters participating in
such offering and (iii) to take all further actions which shall be
reasonably necessary to effect such registration and sale
(including, if the Manager deems it necessary, participating in
road-show presentations).

     The Registrant shall be entitled to include (at its expense)
additional shares of its common stock in a registration effected
pursuant to this Section 10 only if and to the extent the Manager
determines that such inclusion will not adversely affect the
prospects for success of such offering.

     11.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  Without
limitation to any restriction on SIGCORP contained in this
Agreement or in the Merger Agreement, in the event of any change in
SIGCORP Common Stock by reason of stock dividends, splitups,
mergers (other than the Merger), recapitalizations, combinations,
exchange of shares or the like, the type and number of shares or
securities subject to the SIGCORP Option, and the purchase price
per share provided in Section 1, shall be adjusted appropriately to
restore to Indiana its rights hereunder, including the right to
purchase from SIGCORP (or its successors) shares of SIGCORP Common
Stock representing 19.9% of the outstanding SIGCORP Common Stock
for the aggregate Exercise Price calculated as of the date of this
Agreement as provided in Section 1.

     12.  RESTRICTIVE LEGENDS.  Each certificate representing
shares of SIGCORP Common Stock issued to Indiana hereunder, and
Indiana Shares, if any, delivered to SIGCORP at a Closing, shall
include a legend in substantially the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE
REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM
SUCH REGISTRATION IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT
TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE STOCK
OPTION AGREEMENT, DATED AS OF JUNE 11, 1999, A COPY OF WHICH MAY BE
OBTAINED FROM THE ISSUER UPON REQUEST.

It is understood and agreed that: (i) the reference to the resale
restrictions of the Securities Act in the above legend shall be
removed by delivery of substitute certificate(s) without such
reference if Indiana or SIGCORP, as the case may be, shall have
delivered to the other party a copy of a letter from the staff of
the Securities and Exchange Commission, or an opinion of counsel,
in form and substance satisfactory to the other party, to the
effect that such legend is not required for purposes of the
Securities Act; (ii) the reference to the provisions of this
Agreement in the above legend shall be removed by delivery of
substitute certificate(s) without such reference if the shares have
been sold or transferred in compliance with the provisions of this
Agreement and in circumstances that do not require the retention of
such reference; and (iii) the legend shall be removed in its
entirety if the conditions in the preceding clauses (i) and (ii)
are both satisfied.  In addition, such certificates shall bear any
other legend as may be required by law, Certificates representing
shares sold in a registered public offering pursuant to Section 10
shall not be required to bear the legend forth in this Section 12.

     13.  BINDING EFFECT; No Assignment; No Third Party
Beneficiaries.   This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors
and permitted assigns.  Except as expressly provided for in this
Agreement, neither this Agreement nor the rights or the obligations
of either party hereto are assignable, except by operation of law,
or with the written consent of the other party.  Nothing contained
in this Agreement, expressed or implied, is intended to confer upon
any person other than the parties hereto and their respective
permitted assigns any rights or remedies of any nature whatsoever
by reason of this Agreement.  Any Restricted Shares sold by a party
in compliance with the provisions of Section 10 shall, upon
consummation of such sale, be free of the restrictions imposed with
respect to such shares by this Agreement; unless and until such
party shall repurchase or otherwise become the beneficial owner of
such shares, and any transferee of such shares shall not be
entitled to the registration rights of such party.

     14.  SPECIFIC PERFORMANCE.  The parties recognize and agree
that if for any reason any of the provisions of this Agreement are
not performed in accordance with their specific terms or are
otherwise breached, immediate and irreparable harm or injury would
be caused for which money damages would not be an adequate remedy.
Accordingly, each party agrees that, in addition to other remedies,
the other party shall be entitled to an injunction restraining any
violation or threatened violation of the provisions of this
Agreement.  In the event that any action should be brought in
equity to enforce the provisions of the Agreement, neither party
will allege, and each party hereby waives the defense, that there
is adequate remedy at law.

     15.  ENTIRE AGREEMENT.  This Agreement, the Confidentiality
Agreement and the Merger Agreement (including the exhibits and
schedules thereto) constitute the entire agreement among the
parties with respect to the subject matter, hereof and thereof and
supersede all other prior agreements and understandings, both
written and oral, among the parties or any of them with respect to
the subject matter hereof and thereof.

     16.  FURTHER ASSURANCES.  Each party will execute and deliver
all such further documents and instruments and take all such
further action as may be necessary in order to consummate the
transactions contemplated hereby.

     17.  VALIDITY.  The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or
enforceability of the other provisions of this Agreement, which
shall remain in full force and effect.  In the event any court or
other competent authority holds any provisions of this Agreement to
be null, void or unenforceable, the parties hereto shall negotiate
in good faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the
extent permitted by law, the intent of the parties hereto with
respect to such provision and the economic effects thereof.  If for
any reason any such court or regulatory agency determines that
Indiana is not permitted to acquire, or SIGCORP is not permitted to
repurchase pursuant to Section 7, the full number of shares of
SIGCORP Common Stock provided in Section 1 hereof (as the same may
be adjusted), it is the express intention of SIGCORP to allow
Indiana to acquire or to require SIGCORP to repurchase such lesser
number of shares as may be permissible, without any amendment or
modification hereof.  Each party agrees that, should any court or
other competent authority hold any provision of this Agreement or
part hereof to be null, void or unenforceable, or order any party
to take any action inconsistent herewith, or not take any action
required herein, the other party shall not be entitled to specific
performance of such provision or part hereof or to any other
remedy, including but not limited to money damages, for breach
hereof or of any other provision of this Agreement or part hereof
as the result of such holding or order.

     18.  NOTICES.  All notices and other communications hereunder

           INDIANA ENERGY, INC. STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT, dated as of June 11, 1999 by and
between Indiana Energy, Inc., an Indiana corporation ("INDIANA"),
and SIGCORP, INC., an Indiana corporation ("SIGCORP").

     WHEREAS, concurrently with the execution and delivery of this
Agreement, Indiana, SIGCORP and Vectren Corporation, an Indiana
corporation 50% of whose outstanding capital stock is owned by
Indiana and 50% of whose outstanding capital stock is owned by
SIGCORP (the "Company") are entering into an Agreement and Plan of
Merger, dated as of the date hereof (the "Merger Agreement"), which
provides, among other things, upon the terms and subject to the
conditions thereof, for the merger of each of Indiana and SIGCORP
with and into the Company (the "Merger"); and

     WHEREAS, as a condition to Indiana willingness to enter into
the Merger Agreement, SIGCORP has requested that Indiana agree, and
Indiana has so agreed, to grant to SIGCORP an option with respect
to certain shares of Indiana's common stock, on the terms and
subject to the conditions set forth herein.

     NOW, THEREFORE, to induce SIGCORP to enter into the Merger
Agreement, and in consideration of the mutual covenants and
agreements set forth herein and in the Merger Agreement, the
parties hereto agree as follows:

     1.   GRANT OF OPTION.  Indiana hereby grants SIGCORP an
irrevocable option (the "Indiana Option") to purchase up to
5,927,524 shares, subject to adjustment as provided in Section 11
(such shares being referred to herein as the "Indiana Shares"), of
common stock, without par value, of Indiana (the "Indiana Common
Stock") (being 19.9% of the number of shares of Indiana Common
Stock outstanding on the date hereof), together with the associated
purchase rights (the "Indiana Rights"), issued pursuant to the
Indiana Rights Agreement referred to in Section 4.15 of the Merger
Agreement (the "Indiana Rights Agreement"), in the manner set forth
below at a price (the "Exercise Price") per Indiana share of
$22.27, payable, at SIGCORP's option, (a) in cash or (b) subject to
the receipt of approvals of any Governmental Authority required for
Indiana to acquire the SIGCORP Shares (as defined below) from
SIGCORP, and for SIGCORP to issue the SIGCORP Shares to Indiana,
which approvals Indiana and SIGCORP shall use their respective
reasonable best efforts to obtain, in shares of common stock,
without par value, of SIGCORP (the "SIGCORP Shares"), in either
case in accordance with Sections 3 and 4 hereof.  Notwithstanding
the foregoing, in no event shall the number of Indiana Shares for
which the Indiana Option is exercisable exceed 19.9% of the number
of issued and outstanding shares of Indiana Common Stock.  As used
herein, the "Fair Market Value" of any share shall be the average
of the daily closing sales price for such share on the New York
Stock Exchange (the "NYSE") during the five NYSE trading days prior
to the NYSE trading day preceding the date such Fair Market Value
is to be determined.

     2.   EXERCISE OF OPTION.  The Indiana Option may be exercised
by SIGCORP, in whole or in part, at any time or from time to time
after the Merger Agreement becomes terminable by SIGCORP under
circumstances which could entitle SIGCORP to termination fees under
either Section 9.3(a) of the Merger Agreement or Section 9.3(b) of
the Merger Agreement, provided that the events specified in Section
9.3(b)(ii) of the Merger Agreement shall have occurred (regardless
of whether the Merger Agreement is actually terminated or whether
there occurs a closing of any Business Combination involving an
Indiana Target Party or a closing by which an Indiana Target Party
becomes a subsidiary), any such event by which the Merger Agreement
becomes so terminable by SIGCORP being referred to herein as a
"Trigger Event."  Indiana shall notify SIGCORP promptly in writing
of the occurrence of any Trigger Event, it being understood that
the giving of such notice by Indiana shall not be a condition to
the right of SIGCORP to exercise the Indiana Option.  In the event
SIGCORP wishes to exercise the Indiana Option, SIGCORP shall
deliver to Indiana a written notice (an "Exercise Notice")
specifying the total number of Indiana Shares it wishes to
purchase.  If at the time of issuance of any Indiana Shares
pursuant to an exercise of all or part of the Indiana Option
hereunder, Indiana shall not have redeemed the Indiana Rights, or
shall have issued any similar securities, then each Indiana Share
issued pursuant to such exercise shall also represent Indiana
Rights or new rights with terms substantially the same as and at
least as favorable to SIGCORP as are provided under the Indiana
Rights Agreement or any similar agreement then in effect.  Each
closing of a purchase of Indiana Shares (a "Closing") shall occur
at a place, on a date and at a time designated by SIGCORP in an
Exercise Notice delivered at least two business days prior to the
date of the Closing.  The Indiana Option shall terminate upon the
earlier of:  (i) the Effective Time; (ii) the termination of the
Merger Agreement pursuant to Section 9.1 thereof (other than upon
or during the continuance of a Trigger Event); or (iii) 180 days
following any termination of the Merger Agreement upon or during
the continuance of a Trigger Event (or if, at the expiration of
such 180 day period the Indiana Option cannot be exercised by
reason of any applicable judgment, decree, order, law or
regulation, ten business days after such impediment to exercise
shall have been removed or shall have become final and not subject
to appeal, but in no event under this clause (iii) later than the
third anniversary of the date hereof).  Notwithstanding the
foregoing, the Indiana Option may not be exercised if SIGCORP is in
material breach of any of its material representations or
warranties, or in material breach of any of its covenants or
agreements, contained in this Agreement or in the Merger Agreement.
Upon the giving by SIGCORP to Indiana of the Exercise Notice and
the tender of the applicable aggregate Exercise Price, SIGCORP
shall be deemed to be the holder of record of the Indiana Shares
issuable upon such exercise, notwithstanding that the stock
transfer books of Indiana shall then be closed or that certificates
representing such Indiana Shares shall not then be actually
delivered to SIGCORP.

     3.   CONDITIONS TO CLOSING.  The obligation of Indiana to
issue the Indiana Shares to SIGCORP hereunder is subject to the
conditions, which (other than the conditions described in clauses
(i), (iii) and (iv) below) may be waived by Indiana in its sole
discretion, that (i) all waiting periods, if any, under the HSR
Act, applicable to the issuance of the Indiana Shares hereunder
shall have expired or have been terminated; (ii) the Indiana
Shares, and any SIGCORP Shares which are issued in payment of the
Exercise Price, shall have been approved for listing on the NYSE
upon official notice of issuance; (iii) all consents, approvals,
orders or authorizations of or registrations, declarations or
filings with, any federal, state or local administrative agency or
commission or other federal, state or local Governmental Authority,
if any, required in connection with the issuance of the Indiana
Shares or the acquisition of such Indiana Shares by SIGCORP
hereunder shall have been obtained or made, as the case may be,
including, without limitation, the approval of, if applicable, the
issuance of the SIGCORP Shares to Indiana and the acquisition by
Indiana of the SIGCORP shares constituting the Exercise Price
hereunder, and approval of the SEC under the 1935 Act of the
acquisition of the Indiana Shares by SIGCORP; and (iv) no
preliminary or permanent injunction or other order by any court of
competent jurisdiction prohibiting or otherwise restraining such
issuance shall be in effect.

     4.   CLOSING.  At any Closing, (a) Indiana will deliver to
SIGCORP or its designee a single certificate in definitive form
representing the number of Indiana Shares designated by SIGCORP in
its Exercise Notice, such certificate to be registered in the name
of SIGCORP and to bear the legend set forth in Section 12 and (b)
SIGCORP will deliver to Indiana the aggregate Exercise Price for
the Indiana Shares so designated and being purchased by (i) wire
transfer of immediately available funds or certified check or bank
check or (ii) subject to the condition in Section 1(b), a
certificate or certificates representing the number of SIGCORP
Shares being issued by SIGCORP in consideration thereof, as the
case may be.  For the purposes of this Agreement, the number of
SIGCORP Shares to be delivered to Indiana shall be equal to the
quotient obtained by dividing (i) the product of (x) the number of
Indiana Shares with respect to which the Indiana Option is being
exercised and (y) the Exercise Price by (ii) the Fair Market Value
of the SIGCORP Shares at the date immediately preceding the date
the Exercise Notice is delivered to Indiana.  Indiana shall pay all
expenses, and any and all United States federal, state and local
taxes and other charges that may be payable in connection with the
preparation, issue and delivery of stock certificates under this
Section 4 in the name of SIGCORP or such designee of SIGCORP as
shall have obtained appropriate regulatory approval.

     5.   REPRESENTATIONS AND WARRANTIES OF INDIANA.  Indiana

Option in accordance with its terms, and at all times from the date

amount being subject to adjustment as provided in Section 11, all
of which, upon their issuance and delivery in accordance with the
terms of this Agreement, will be validly issued, fully paid and
nonassessable, (f) upon delivery of the Indiana Shares to SIGCORP
upon the exercise of the Indiana Option in accordance with its
terms, SIGCORP will acquire the Indiana shares free and clear of

     number of Indiana Shares purchasable pursuant to the Indiana
     Option (or portion thereof with respect to which SIGCORP is
     exercising its rights under this Section 7), but only if the
     Market/Offer Price is greater than the Exercise Price;

          (ii) the product of (x) the sum of (A) the Exercise Price
     paid by SIGCORP per Indiana Share acquired pursuant to the
     Indiana Option and (B) the difference between the Market/Offer
     Price and the Exercise Price, but only if the Market/Offer
     Price is greater than the Exercise Price, and (y) the number
     of Indiana Shares so to be repurchased pursuant to this
     Section 7.  For purposes of this clause (ii), the Offer Price
     shall be the highest price per share offered pursuant to a
     tender or exchange offer or other Business Combination offer
     during the Repurchase Period prior to the delivery by SIGCORP
     of a notice of repurchase.

     (b)  REDELIVERY OF SIGCORP SHARES.  If SIGCORP elected to
purchase Indiana Shares pursuant to the exercise of the Indiana
Option by the issuance and delivery of SIGCORP Shares, then Indiana
shall, if so requested by SIGCORP, in fulfillment of its obligation
pursuant to clause (A) of Section 7(a)(ii)(x) (that is, with
respect to the Exercise Price only and without limitation to its
obligation to pay additional consideration under clause (B) of
Section 7(a)(ii)(x)), redeliver the certificate for such SIGCORP
Shares to SIGCORP free and clear of all liens, claims, damages,
charges and encumbrances of any kind or nature whatsoever,
provided, however, that if less than all of the Indiana Shares
purchased by SIGCORP pursuant to the Indiana Option are to be
repurchased pursuant to this Section 7, then SIGCORP shall issue to
Indiana a new certificate representing those SIGCORP Shares which
are not due to be redelivered to SIGCORP pursuant to this Section
7 as they constituted payment of the Exercise Price for the Indiana
Shares not being repurchased.

     (c)  PAYMENT AND REDELIVERY OF INDIANA OPTION OR SHARES.  In
the event SIGCORP exercises its rights under this Section 7,
Indiana shall, within 10 business days thereafter, pay the required
amount to SIGCORP in immediately available funds and SIGCORP shall
surrender to Indiana the Indiana Option or the certificates
evidencing the Indiana Shares purchased by SIGCORP pursuant
thereto, and SIGCORP shall warrant that it owns the Indiana Option
or such shares and that the Indiana Option or such shares are then
free and clear of all liens, claims, damages, charges and
encumbrances of any kind or nature whatsoever.

     (d)  SIGCORP CALL.  If SIGCORP has elected to purchase Indiana
Shares pursuant to the exercise of the Indiana Option by the
issuance and delivery of SIGCORP Shares, notwithstanding that
SIGCORP may no longer hold any such Indiana Shares or that SIGCORP
elects not to exercise its other rights under this Section 7,
SIGCORP may require, at any time or from time to time prior to June
11, 2000 (provided that such date shall be extended to December 31,
2000 under the circumstances where the date after which either
party may terminate the Merger Agreement pursuant to Section 9.1(b)
of the Merger Agreement has been extended to December 31, 2000),
Indiana to sell to SIGCORP any such SIGCORP Shares at the price
attributed to such SIGCORP Shares pursuant to Section 4 plus
interest at the rate of 7% per annum on such amount from the
Closing Date relating to the exchange of such SIGCORP Shares
pursuant to Section 4 to the closing date under this Section 7(d)
less any dividends on such SIGCORP Shares paid during such period
or declared and payable to stockholders of record on a date during
such period.

     (e)  REPURCHASE PRICE REDUCED AT SIGCORP'S OPTION.  In the
event the repurchase price specified in Section 7(a) would subject
the purchase of the Indiana Option purchased by SIGCORP pursuant to
the Indiana Option to a vote of the shareholders of Indiana
pursuant to applicable law or Indiana's Amended and Restated
Articles of Incorporation, then SIGCORP may, at its election,
reduce the repurchase amount which would permit such repurchase
without the necessity for such a shareholder vote.

     8.   VOTING OF SHARES.  Following the date hereof and prior to
the fifth anniversary of the date hereof (the "Expiration Date"),
each party shall vote any shares of capital stock of the other
party acquired by such party pursuant to this Agreement
("Restricted Shares"), including any SIGCORP Shares issued pursuant
to Section 1(b) or otherwise beneficially owned (within the meaning
of Rule 13d-3 promulgated under the Securities Exchange Act of
1934, as amended (the "Exchange Act")) by such party on each matter
submitted to a vote of shareholders of such other party for and
against such matter in the same proportion as the vote of all other
shareholders of such other party are voted (whether by proxy or
otherwise) for and against such matter.

     9.   RESTRICTIONS ON TRANSFER.

     (a)  RESTRICTIONS ON TRANSFER.  Prior to the Expiration Date,
neither party shall, directly or indirectly, by operation of law or
otherwise, sell, assign, pledge, or otherwise dispose of or
transfer any Restricted Shares beneficially owned by such party,
other than (i) pursuant to Section 7, or (ii) in accordance with
Section 9(b) or Section 10.

     (b)  PERMITTED SALES.  Following the termination of the Merger
Agreement, a party shall be permitted to sell any Restricted Shares
beneficially owned by it if such sale is made pursuant to a tender
or exchange offer that has been approved or recommended, or
otherwise determined to be fair to and in the best interests of the
shareholders of the other party, by a majority of the members of
the Board of Directors of such other party, which majority shall
include a majority of directors who were directors prior to the
announcement of such tender or exchange offer.

     10.  REGISTRATION RIGHTS.  Following the termination of the
Merger Agreement, each party hereto (a "Designated Holder") may by
written notice (the "Registration Notice") to the other party (the
"Registrant") request the Registrant to register under the
Securities Act all or any part of the Restricted Shares
beneficially owned by such Designated Holder (the "Registrable
Securities") pursuant to a bona fide firm commitment underwritten
public offering in which the Designated Holder and the underwriters
shall effect as wide a distribution of such Registrable Securities
as is reasonably practicable and shall use their best efforts to
prevent any person (including any Group (as used in Rule 13d-5
under the Exchange Act)) and its affiliates from purchasing through
such offering Restricted Shares representing more than 1% of the
outstanding shares of common stock of the Registrant on a fully
diluted basis (a "Permitted Offering").  The Registration Notice
shall include a certificate executed by the Designated Holder and
its proposed managing underwriter, which underwriter shall be an
investment banking firm of nationally recognized standing (the
"Manager"), stating that (i) they have a good faith intention to
commence promptly a Permitted Offering and (ii) the Manager in good
faith believes that, based on the then prevailing market
conditions, it will be able to sell the Registrable Securities at
a per share price equal to at least 80% of the then Fair Market
Value of such shares.  The Registrant (and/or any person designated
by the Registrant) shall thereupon have the option exercisable by
written notice delivered to the Designated Holder within 10
business days after the receipt of the Registration Notice,
irrevocably to agree to purchase all or any part of the Registrable
Securities proposed to be so sold for cash at a price (the "Option
Price") equal to the product of (i) the number of Registrable
Securities to be so purchased by the Registrant and (ii) the then
Fair Market Value of such shares.  Any such purchase of Registrable
Securities by the Registrant (or its designee) hereunder shall take
place at a closing to be held at the principal executive offices of
the Registrant or at the offices of its counsel at any reasonable
date and time designated by the Registrant and/or such designee in
such notice within 20 business days after delivery of such notice.
Any payment for the shares to be purchased shall be made by
delivery at the time of such closing of the Option Price in
immediately available funds.

     If the Registrant does not elect to exercise its option
pursuant to this Section 10 with respect to all Registrable
Securities, it shall use its best efforts to effect, as promptly as
practicable, the registration under the Securities act of the
unpurchased Registrable Securities proposed to be so sold;
provided, however, that (i) neither party shall be entitled to more
than an aggregate of two effective registration statements
hereunder and (ii) the Registrant will not be required to file any
such registration statement during any period of time (not to
exceed 40 days after such request in the case of clause (A) below
or 90 days in the case of clauses (B) and (C) below) when (A) the
Registrant is in possession of material non-public information
which it reasonably believes would be detrimental to be disclosed
at such time and, in the opinion of counsel to the Registrant, such
information would have to be disclosed if a registration statement
were filed at that time; (B) the Registrant is required under the
Securities Act to include audited financial statements for any
period in such registration statement and such financial statements
are not yet available for inclusion in such registration statement;
or (C) the Registrant determines, in its reasonable judgment, that
such registration would interfere with any financing, acquisition
or other material transaction involving the Registrant or any of
its affiliates.  The Registrant shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant to
this Section 10 to be qualified for sale under the securities or
Blue-Sky laws of such jurisdictions as the Designated Holder may
reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however,
that the Registrant shall not be required to qualify to do business
in, or to consent to general service of process in, any
jurisdiction by reason of this provision.

     The registration rights set forth in this Section 10 are
subject to the condition that the Designated Holder shall provide
the Registrant with such information with respect to such holder's
Registrable Securities, the plans for the distribution thereof, and
such other information with respect to such holder as, in the
reasonable judgment of counsel for the Registrant, is necessary to
enable the Registrant to include in such registration statement all
material facts required to be disclosed with respect to a
registration thereunder.

     A registration effected under this Section 10 shall be
effected at the Registrant's expense, except for underwriting
discounts and commissions and the fees and the expenses of counsel
to the Designated Holder, and the Registrant shall provide to the
underwriters such documentation (including certificates, opinions
of counsel and "comfort" letters from auditors) as are customary in
connection with underwritten public offerings as such underwriters
may reasonably require.  In connection with any such registration,
the parties agree (i) to indemnify each other and the underwriters
in the customary manner, (ii) to enter into an underwriting
agreement in form and substance customary for transactions of such
type with the Manager and the other underwriters participating in
such offering and (iii) to take all further actions which shall be
reasonably necessary to effect such registration and sale
(including, if the Manager deems it necessary, participating in
road-show presentations).

     The Registrant shall be entitled to include (at its expense)
additional shares of its common stock in a registration effected
pursuant to this Section 10 only if and to the extent the Manager
determines that such inclusion will not adversely affect the
prospects for success of such offering.

     11.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  Without
limitation to any restriction on Indiana contained in this
Agreement or in the Merger Agreement, in the event of any change in
Indiana Common Stock by reason of stock dividends, splitups,
mergers, (other than the Merger), recapitalizations, combinations,
exchange of shares or the like, the type and number of shares or
securities subject to the Indiana Option, and the purchase price
per share provided in Section 1, shall be adjusted appropriately to
restore to SIGCORP its rights hereunder, including the right to
purchase from Indiana (or its successors) shares of Indiana Common
Stock representing 19.9% of the outstanding Indiana Common Stock
for the aggregate Exercise Price calculated as of the date of this
Agreement as provided in Section 1.

     12.  RESTRICTIVE LEGENDS.  Each certificate representing
shares of Indiana Common Stock issued to SIGCORP hereunder, and
SIGCORP Shares, if any, delivered to Indiana at a Closing, shall
include a legend in substantially the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE
REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM
SUCH REGISTRATION IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT
TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE STOCK
OPTION AGREEMENT, DATED AS OF JUNE 11, 1999, A COPY OF WHICH MAY BE
OBTAINED FROM THE ISSUER UPON REQUEST.

It is understood and agreed that:  (i) the reference to the resale
restrictions of the Securities Act in the above legend shall be
removed by delivery of substitute certificate(s) without such
reference if SIGCORP or Indiana, as the case may be, shall have
delivered to the other party a copy of a letter from the staff of
the Securities and Exchange Commission, or an opinion of counsel,
in form and substance satisfactory to the other party, to the
effect that such legend is not required for purposes of the
Securities Act; (ii) the reference to the provisions of this
Agreement in the above legend shall be removed by delivery of
substitute certificate(s) without such reference if the shares have
been sold or transferred in compliance with the provisions of this
Agreement and in circumstances that do not require the retention of
such reference; and (iii) the legend shall be removed in its
entirety if the conditions in the preceding clauses (i) and (ii)
are both satisfied.  In addition, such certificates shall bear any
other legend as may be required by law.  Certificates representing
shares sold in a registered public offering pursuant to Section 10
shall not be required to bear the legend set forth in this Section
12.

     13.  BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY
BENEFICIARIES.  This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors
and permitted assigns.  Except as expressly provided for in this
Agreement, neither this Agreement nor the rights or the obligations
of either party hereto are assignable, except by operation of law,
or with the written consent of the other party.  Nothing contained
in this Agreement, expressed or implied, is intended to confer upon
any person other than the parties hereto and their respective
permitted assigns any rights or remedies of any nature whatsoever
by reason of this Agreement.  Any Restricted Shares sold by a party
in compliance with the provisions of Section 10 shall, upon
consummation of such sale, be free of the restrictions imposed with
respect to such shares by this Agreement, unless and until such
party shall repurchase or otherwise become the beneficial owner of
such shares, and any transferee of such shares shall not be
entitled to the registration rights of such party.

     14.  SPECIFIC PERFORMANCE.  The parties recognize and agree
that if for any reason any of the provisions of this Agreement are
not performed in accordance with their specific terms or are
otherwise breached, immediate and irreparable harm or injury would
be caused for which money damages would not be an adequate remedy.
Accordingly, each party agrees that, in addition to other remedies,
the other party shall be entitled to an injunction restraining any
violation or threatened violation of the provisions of this
Agreement.  In the event that any action should be brought in
equity to enforce the provisions of the Agreement, neither party
will allege, and each party hereby waives the defense, that there
is adequate remedy at law.

     15.  ENTIRE AGREEMENT.  This Agreement, the Confidentiality
Agreement and the Merger Agreement (including the exhibits and
schedules thereto) constitute the entire agreement among the
parties with respect to the subject matter hereof and thereof and
supersede all other prior agreements and understandings, both
written and oral, among the parties or any of them with respect to
the subject matter hereof and thereof.

     16.  FURTHER ASSURANCES.  Each party will execute and deliver
all such further documents and instruments and take all such
further action as may be necessary in order to consummate the
transactions contemplated hereby.

     17.  VALIDITY.  The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or
enforceability of the other provisions of this Agreement, which
shall remain in full force and effect.  In the event any court or
other competent authority holds any provisions of this Agreement to
be null, void or unenforceable, the parties hereto shall negotiate
in good faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the
extent permitted by law, the intent of the parties hereto with
respect to such provision and the economic effects thereof.  If for
any reason any such court or regulatory agency determines that
SIGCORP is not permitted to acquire, or Indiana is not permitted to
repurchase pursuant to Section 7, the full number of shares of
Indiana Common Stock provided in Section 1 hereof (as the same may
be adjusted), it is the express intention of Indiana to allow
SIGCORP to acquire or to require Indiana to repurchase such lesser
number of shares as may be permissible, without any amendment or
modification hereof.  Each party agrees that, should any court or
other competent authority hold any provision of this Agreement or
part hereof to be null, void or unenforceable, or order any party
to take any action inconsistent herewith, or not take any action
required herein, the other party shall not be entitled to specific
performance of such provision or part hereof or to any other
remedy, including but not limited to money damages, for breach
hereof or of any other provision of this Agreement or part hereof
as the result of such holding or order.

     18.  NOTICES.  All notices and other communications hereunder
shall be in writing and shall be deemed given if (i) delivered
personally, or (ii) sent by reputable overnight courier service, or
(iii) telecopied (which is confirmed), or (iv) five days after
being mailed by registered or certified mail (return receipt
requested) to the parties at the following addresses (or at such

principles.  Each of the parties hereto (a) consents to submit

request for leave from any such court and (c) agrees that it will
not bring any action relating to this Agreement or any of the
transactions contemplated by this Agreement in any court other than
a federal court sitting in the State of Indiana or an Indiana state

     23.  AMENDMENTS; WAIVER.  This Agreement may be amended by the
parties hereto and the terms and conditions hereof may be waived
only by an instrument in writing signed on behalf of each of the
parties hereto, or, in the case of a waiver, by an instrument
signed on behalf of the party waiving compliance.

     24.  EXTENSION OF TIME PERIODS.  The time periods for exercise
of certain rights under Sections 2 and 7 shall be extended:  (i) to
the extent necessary to obtain all regulatory approvals for the
exercise of such rights, and for the expiration of all statutory

liability under Section 16(b) of the Exchange Act by reason of such
exercise.

     25.  REPLACEMENT OF INDIANA OPTION.  Upon receipt by Indiana
of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Agreement, and (in the case of
loss, theft or destruction) of reasonably satisfactory

INDIANA ENGERGY                                           SIGCORP

FOR IMMEDIATE RELEASE

                 INDIANA ENERGY AND SIGCORP AGREE
                 TO $1.9 BILLION MERGER OF EQUALS
                   TO FORM VECTREN CORPORATION

     INDIANAPOLIS and EVANSVILLE, Ind.--(BUSINESS WIRE)-- June 14,
1999--Indiana Energy Inc. (NYSE:IEI - news) and SIGCORP Inc.
(NYSE:SIG - news) today announced that they have signed a
definitive agreement to combine into a new holding company, to be
named Vectren Corp.  Under the agreement, SIGCORP shareholders will
receive one and one-third shares of the new
company's common stock for each share of SIGCORP they currently
hold.  Indiana Energy
shareholders will receive one share of the new company's common
stock for each share of Indiana
Energy they currently hold.

     The tax-free stock-for-stock transaction would create a
combined company with a total enterprise value of approximately
$1.9 billion ($1.4 billion in equity; $0.5 billion in debt and
subsidiary preferred stock) based upon Indiana Energy's closing
stock price of $22.563 and SIGCORP's closing stock price of $29.50
per share on Friday, June 11, 1999. The transaction, which has been
approved by the boards of directors of both companies, is expected
to be accounted for as a pooling of interests and is anticipated to
be immediately accretive excluding one-time charges related to
combining the companies.

     The merger combines two Indiana companies with strong balance
sheets, low-cost operations, growing service areas, diversified
product portfolios, and track records of delivering superior
shareholder value.  Through its utility subsidiaries, Vectren will
offer gas and/or electricity to more than 650,000 customers in
adjoining service areas that cover nearly two-thirds of Indiana.
Vectren's non-utility subsidiaries will offer energy-related
products and services, fiber-optic based telecommunication
services, materials management, locating and trenching services and
energy marketing to customers throughout the surrounding region.

     Niel C. Ellerbrook, Indiana Energy's president and chief
executive officer, said, "The energy industry is converging and
successful participants will be able to offer a broad array of
products and services to customers. With this combination, our
asset mix will be split evenly between gas and electric, balancing
our earnings while positioning the combined company to deliver
energy in whatever form our customers need.

     "We have a lot in common,'' Ellerbrook continued. "We are a
combination of already strong companies, with histories of
delivering superior shareholder value. Our combined goal is to grow
earnings per share on average by 10% a year and for earnings from
non-regulated operations to contribute over 25% of the consolidated
total by 2003. We also expect each company's long track record of
increasing dividends to continue. SIGCORP and Indiana Energy each
boast an entrepreneurial culture, an outstanding work force, firm
Indiana roots, and a drive to aggressively pursue the opportunities
presented by the changing energy industry. Together, we can capture
those opportunities, thereby creating enhanced value for our
shareholders.''

     Andrew E. Goebel, SIGCORP's president and chief operating
officer, said, "Simply put, this
combination makes sense. It's a marriage of strengths. SIGCORP has
the lowest average retail electric rate in the state and each
company has among the lowest gas rates. Furthermore, over the last
several years, our customer growth rates have exceeded the national
average.

                             -More-

     "We have known Indiana Energy for years and, in fact, are
partners in Energy Systems Group, LLC, a joint venture formed in
1997 that provides energy-related performance contracting services.
As one company, we will serve 650,000 Indiana customers, providing
superior customer service and some of the most competitive energy
prices in the country. This combination will enable us to
cross-sell a greater array of products and services to our existing
and future customer base and to make the necessary investment in
technology to continue delivering first-class customer service and
other business applications in an increasingly competitive
environment. We believe that the combination of these two Indiana
companies will strengthen our commitment to our communities and
provide customer benefits that further enhance Indiana's economic
development efforts. We intend to be a focused, high-quality,
high-service regional player in our regulated businesses and to
seek and develop new revenue opportunities in non-regulated
businesses,'' Goebel concluded.

     The companies expect to realize net merger savings of nearly
$200 million over 10 years from the elimination of duplicate
corporate and administrative programs and greater efficiencies in
operations, business processes and purchasing. Position reductions
due to the merger are expected to be less than 7 percent of the
consolidated workforce, or about 120 positions out of a total
workforce of approximately 1,850. Both companies will seek
alternatives to minimize the impact on current personnel. Available
options would include a combination of normal attrition, retraining
and retirements, as well as selective hiring and the addition of
positions in growing business areas. All union contracts will be
honored.

     Following the merger, Niel Ellerbrook will be chairman and
chief executive officer of the new company and Andrew Goebel will
be president and chief operating officer. Indiana Energy's
chairman, L.A. Ferger, and SIGCORP's chairman and CEO, Ronald G.
Reherman, both will retire upon completion of the merger but will
serve on the board of directors of the new company. Vectren's board
will consist of 16 directors; in addition to Ferger, Ellerbrook,
Reherman and Goebel, Indiana Energy and SIGCORP each will designate
six directors.

     Indiana Energy's and SIGCORP's utility companies will remain
separate subsidiaries of Vectren and will continue to operate under
the names Indiana Gas Company Inc. and Southern Indiana Gas and
Electric Company (SIGECO), respectively. The companies will retain
and build upon their existing brand identities and customer
loyalties in their respective service territories. Under the merger
agreement, the corporate headquarters of Vectren and of SIGECO will
be in Evansville. Indiana Gas Co. will continue to be headquartered
in Indianapolis, where it has been for over 50 years.

     Vectren's board of directors will set the company's dividend
policy. However, the companies anticipate that the dividend, on an
equivalent share basis, on the combined company's stock would be
set at or above the current dividend levels at both companies.

     The merger is conditioned, among other things, upon the
approvals of the shareholders of each company and customary
regulatory approvals. The companies anticipate that the regulatory
processes can be completed in six to nine months.
