         The Company is an operating  public utility  engaged in the business of
providing  gas  utility  service  in the  State  of  Indiana.  The  Company  was
incorporated under the laws of the State of Indiana on July 16, 1945. All of the
outstanding  shares of Common Stock of the Company are owned by Indiana  Energy,
Inc., which is a public holding company.

         At  September  30,  1997,  the Company  supplied  gas to  approximately

Haute, Marion, New Albany,  Columbus,  Jeffersonville,  New Castle and Richmond.
The Company  does not provide gas service in  Indianapolis  although its general

                       RATIO OF EARNINGS TO FIXED CHARGES

         The ratio of  earnings  to fixed  charges of the Company for the fiscal
years ended  September 30, 1996,  1995,  1994,  1993 and 1992 was 4.6; 4.1; 4.1;
3.5;  and 3.5,  respectively.  The ratio of  earnings  to fixed  charges  of the
Company for the twelve month period ended June 30, 1997 was 4.4. For the purpose
of computing the ratio of earnings to fixed charges, (i) earnings consist of net
income to which have been added income taxes,  investment  tax credits and fixed

discount and expense, and the estimated interest component of rents.


                                 USE OF PROCEEDS

         The Company may use a portion of the net proceeds  from the sale of the
Debt Securities offered hereby to refinance certain series of its long-term debt
(depending  upon  interest  rates,  market  prices and other  factors).  The net
proceeds from the sale of Debt  Securities  not used to refinance  such existing
indebtedness  will be applied to  finance,  in part,  the  Company's  continuing
construction program, for the payment of obligations incurred in connection with
such  refinancing or such  construction  expenditures,  and for other  corporate
purposes.

         Capital  expenditures  for the  fiscal  year  1997  were  approximately
$72,000,000  and the Company  expects  that  approximately  $68,000,000  will be
expended in fiscal year 1998 and  approximately  $63,000,000 will be expended in
fiscal year 1999. In fiscal 1997, 58% of the Company's capital  expenditures was
provided by funds  generated  internally  (utility  income less  dividends  plus
charges to utility income not requiring  funds).  In fiscal 1996, 70% of capital
expenditures was provided by funds generated internally.

whole or in part;  (8) any  mandatory  or  optional  sinking  fund or  analogous
provisions;  (9) the  denominations  in which  any  Offered  Securities  will be

premium,  if any) and  interest  on the Offered  Securities  will be payable (if

Limitations on Liens

         The Company has agreed that, so long as any of the Debt  Securities are
outstanding, it will not create or suffer to be created or to exist any mortgage
on, pledge of, or other lien on or security  interest in ("Lien"),  any property
of the Company now owned or hereafter  acquired,  securing any  indebtedness for
money  borrowed  ("Debt"),  without  first  offering  to the Holder of each Debt
Security an undertaking by the Company to make effective  provision whereby such
Debt  Security  shall  be  equally  and  ratably  secured  with any and all such
indebtedness and with any other  indebtedness  similarly  entitled to be equally
and ratably  secured  (which offer may only be accepted by any Holder in writing
delivered to the Company on or prior to the 30th day  following  the date of the
Company's  notice) and in accordance  with such  provisions as are acceptable to
the Trustee.  However,  these  restrictions on Liens do not apply to nor prevent
the  creation or  existence  of: (i)  certain  governmental  and similar  Liens,
pledges and deposits  described in the  Indenture;  leases made,  or existing on
property acquired,  in the ordinary course of business (including leases made in
sale and lease-back transactions); and zoning restrictions,  easements, licenses
or restrictions on the use of real property or minor irregularities in the title
thereto, which do not, in the opinion of the Company,  materially impair the use
of such property in the operation of the business of the Company or the value of
such property for the purpose of such

                                                        -4-





business;  (ii) Liens on any property  acquired,  constructed or improved by the
Company  after  the  date  of  the  Indenture   which  are  created  or  assumed
contemporaneously with, or within 120 days after, such acquisition or completion
of such construction or improvement, or within six months thereafter pursuant to
a firm  commitment for financing  arranged with a lender or investor within such
120-day  period,  to secure or provide for the payment of all or any part of the
purchase price of such property or the cost of such  construction or improvement
incurred after the date of the Indenture,  or, in addition to Liens contemplated
by clause (iii) below, Liens on any property existing at the time of acquisition
thereof, so long as the Liens do not apply to any property  theretofore owned by
the Company other than, in the case of any such construction or improvement, any
theretofore unimproved real property on which the property so constructed or the
improvement is located;  (iii) existing Liens on any property or indebtedness of
a  corporation  which is merged with or into or  consolidated  with the Company;
(iv)  Liens in  favor  of the  United  States  of  America,  any  State,  or any
department,  agency or  instrumentality  or  political  subdivision  of any such
jurisdiction, to secure partial, progress, advance or other payments pursuant to
any contract or statute or to secure any  indebtedness  incurred for the purpose
of financing all or any part of the purchase  price of the cost of  constructing
or improving the property subject to such Liens, including,  without limitation,
Liens to secure Debt of the pollution  control or industrial  revenue bond type;
(v) Liens to secure  loans to the  Company  maturing  within 12 months  from the
creation thereof and made in the ordinary course of business;  (vi) Liens on any
property  (including  any natural gas, oil or other mineral  property) to secure
all or part of the cost of  exploration,  drilling or development  thereof or to
secure Debt incurred to provide funds for any such purpose;  and (vii) Liens for
the sole  purpose of  extending,  renewing or replacing in whole or in part Debt
secured by any Lien  referred  to in clauses  (i)  through  (vi) or this  clause
(vii),  so long as the principal  amount of Debt secured thereby does not exceed
the principal  amount of Debt so secured at the time of such extension,  renewal
or replacement,  and that such  extension,  renewal or replacement is limited to
all or a part  of the  property  or  indebtedness  which  secured  the  Lien  so
extended, renewed or replaced (plus improvements on such property).

Events of Default

         The following  constitute  Events of Default  under the Indenture  with
respect  to Debt  Securities  of any  series:  (1)  default  in the  payment  of
principal  of (or  premium,  if any,  on) any  Debt  Security  when  due and the
continuation of such default for a period of three Business Days thereafter; (2)
default  in the  payment  of  interest  on any  Debt  Security  when due and the

thereafter; (4) default in the performance or breach of any covenant or warranty
of the Company in the Indenture  (other than a covenant or warranty  included in

other than such series),  and the continuation thereof for 60 days after written
notice to the Company as provided in the  Indenture;  (5) default in the payment
of principal,  premium,  if any, or interest on (after any applicable  period of
grace),  or acceleration of,  indebtedness  evidenced by any other series issued
under the Indenture or any other  mortgage,  indenture or  instrument,  or other
evidence of  indebtedness  of the Company for  borrowed  money,  in an aggregate
amount  exceeding  $10,000,000,  which default is not rescinded or annulled,  or
indebtedness not discharged,  within 90 days after written notice to the Company
as provided in the Indenture;  (6) certain  events of bankruptcy,  insolvency or
reorganization; and (7) any other Event of Default provided with respect to Debt
Securities of a particular series.

         If an Event of Default with respect to the Debt  Securities  occurs and
is continuing,  either the Trustee or the Holders of 33% in aggregate  principal
amount of the outstanding  Debt  Securities may declare the principal  amount of
all Debt  Securities  to be due and payable  immediately.  At any time after the
declaration of  acceleration  with respect to the Debt Securities has been made,
but before a judgment or decree based on  acceleration  has been  obtained,  the
Holders of a majority in principal  amount of the  outstanding  Debt  Securities
may, under certain circumstances, rescind and annul such acceleration.

         The Indenture  provides that, subject to the duty of the Trustee during
default to act with the required  standard of care, the Trustee will be under no
obligation  to exercise any of its rights or powers  under the  Indenture at the
request or  direction  of any of the  Holders,  unless such  Holders  shall have
offered to the Trustee reasonable indemnity.  Subject to such provisions for the
indemnification of the Trustee, the Holders of a majority in principal amount of
the outstanding  Debt Securities will have the right to direct the time,  method
and place of conducting any proceeding for any remedy  available to the Trustee,
or exercising any trust or

                                                        -5-





power conferred on the Trustee,  with respect to the Debt Securities.  The right
of a Holder of any Debt  Security to institute a proceeding  with respect to the
Indenture  is subject to certain  conditions  precedent,  but each Holder has an
absolute right to receive  payment of principal,  premium,  if any, and interest
when due and to institute  suit for the  enforcement  of any such  payment.  The
Indenture  provides that the Trustee,  within 90 days after the  occurrence of a
default with respect to the Debt Securities,  is required to give the Holders of
the Debt  Securities  notice of such default,  unless cured or waived;  provided
that,  except in the case of default in the payment of  principal or of interest
on any Debt  Security,  the Trustee may withhold such notice if it determines it
is in the interest of such Holders to do so and the Trustee must  withhold  such
notice for 45 days in the event of a default described in clause 4 of the second
preceding paragraph.

         The Company is required to furnish  annually to the Trustee a statement
as to the  performance  by the Company of certain of its  obligations  under the
Indenture and as to any default in such performance.

         Other than the restrictions on the Issuance of additional  secured Debt
described  above,  there are no provisions of the Indenture which afford Holders
of the Debt Securities protection in the event of a highly leveraged transaction
involving  the Company.  However,  such a transaction  would require  regulatory
approval and  management of the Company  believes  that such  approval  would be
unlikely in a highly leveraged context.

Consolidation, Merger, Sale or Conveyance

         The Indenture provides that the Company may, without the consent of the
holders of the Debt Securities,  consolidate with, or convey,  transfer or lease
its property and assets substantially as an entity to another corporation,  only
if in any such case (i) if the Company is not the  continuing  corporation,  the
successor  corporation  shall assume by a  supplemental  indenture the Company's
obligations under the Indenture and (ii) immediately after giving effect to such
transaction,  no Event of Default,  and no event which after  notice or lapse of
time would become an Event of Default, shall have occurred and be continuing.

Modification of the Indenture

         The  Indenture  contains  provisions  permitting  the  Company  and the
Trustee,  with the  consent  of the  Holders  of not  less  than a  majority  in
principal  amount  (calculated as provided in the Indenture) of the  Outstanding
Securities, if all series of Outstanding Securities are affected, or the Holders
of a majority in  aggregate  principal  amount of each  series  affected by such
modification,  in case  one or  more,  but  less  than  all,  of the  series  of
Outstanding Securities are affected, to modify the Indenture or any supplemental
indenture  or the rights of the  Holders of the Debt  Securities  of any series;
provided that no such modification shall,  without the consent of the Holders of
each Debt Security affected  thereby,  change the maturity of any Debt Security,
or reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any amount payable upon redemption of any
Debt  Security,  or reduce the overdue  rate  thereof or change the  currency of
payment of principal or interest on any Debt Security or reduce the above stated
percentage  in principal  amount of  Outstanding  Securities  the consent of the
Holders of which is required for  modification  or amendment of the Indenture or
for  waiver of certain  defaults,  or change any  obligation  of the  Company to
maintain an office or agency in each Place of Payment.

         The  Indenture  also  permits  the Company and the Trustee to amend the
Indenture  in certain  circumstances  without  the consent of the Holders of any
Debt  Securities to evidence the merger of the Company or the replacement of the
Trustee and for certain other purposes.

indicated in their reports included or incorporated by reference herein, and are
incorporated  herein in reliance  upon the  authority of said firm as experts in
accounting and auditing in giving said reports.

         The  statements  as to matters of law and legal  conclusions  under the
caption  "Description  of the Debt  Securities"  have been  reviewed by Barnes &
Thornburg, counsel for the Company, and are made on the authority of said firm.


                                 LEGAL OPINIONS

         The validity of the Debt Securities will be passed upon for the Company
by Barnes & Thornburg,  1313 Merchants Bank Building,  11 South Meridian Street,
Indianapolis,  Indiana 46204,  counsel for the Company, and for the Underwriters
by Reid & Priest LLP, 40 West 57th Street,  New York, New York 10019, which will
rely on Barnes & Thornburg as to matters of Indiana law.


                              PLAN OF DISTRIBUTION

         The Company may sell the Debt  Securities  to or through  underwriters,
and also may sell the Debt  Securities  directly to other  purchasers or through
dealers or agents.  Such  underwriters  may include Merrill Lynch & Co. and/or a
group of underwriters represented by firms including Merrill Lynch & Co. Merrill
Lynch & Co. may also act as agent.

         The  distribution  of the Debt  Securities may be effected from time to
time in one or more  transactions  at a fixed  price  or  prices,  which  may be
changed,  or at market prices  prevailing at the time of sale, at prices related
to such prevailing market prices or at negotiated prices.

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

         Under   agreements   which  may  be  entered   into  by  the   Company,
underwriters, dealers and agents who participate in the distribution of the Debt
Securities may be entitled to  indemnification  by the Company  against  certain
liabilities,  including  liabilities  under the Act, or to contribution from the
Company with respect to payments which the  underwriters,  dealers or agents may
be required to make in respect thereof.

         If so indicated in a Prospectus Supplement,  the Company will authorize
underwriters  or other persons acting as the Company's  agents to solicit offers
by  certain  institutions  to  purchase  the Debt  Securities  from the  Company
pursuant to  contracts  providing  for payment  and  delivery on a future  date.
Institutions  with which  such  contracts  may be made  include  commercial  and
savings  banks,  insurance  companies,   pension  funds,  investment  companies,
educational  and  charitable  institutions  and  others,  but in all cases  such
institutions  must be approved by the Company.  The obligations of any purchaser
under any such contract  will be subject to the  condition  that the purchase of
the Offered Securities shall not at the time of delivery be prohibited under the
laws of the  jurisdiction to which such purchaser is subject.  The  underwriters
and  such  other  agents  will not have any  responsibility  in  respect  of the
validity or performance of such contracts.


                                                        -7-





         In connection  with the offering of the Debt  Securities,  underwriters
may purchase and sell the Debt Securities in the open market. These transactions
may include  overallotment  and stabilizing  transactions and purchases to cover
short  positions  credited by the  underwriters in connection with the offering.
The  underwriters  also may impose a penalty bid,  whereby  selling  concessions
allowed to  broker-dealers in respect of the securities sold in the offering may
be reclaimed by the  underwriters if such Debt Securities are repurchased by the
underwriters  in  stabilizing  or covering  transactions.  These  activities may
stabilize, maintain or otherwise affect the market price of the Debt Securities,
which may be higher  than the price  that  might  otherwise  prevail in the open
market; and these activities, if commenced, may be discontinued at any time.

Item 15.  Indemnification of Directors and Officers.

           The  following  discussion of the  indemnification  provisions of the
Indiana Business  Corporation Law (Indiana Code ss. 23-1-37) (the "BCL"),  which
applies  to the  Company,  is a  summary,  is not meant to be  complete,  and is
qualified in its entirety by reference to the BCL.

           The  BCL   authorizes  a  corporation  to  indemnify  its  directors,
officers,  employees and agents against expenses in certain proceedings provided
such person (i) acted in good faith,  (ii)  reasonably  believed if acting in an
official capacity, that his conduct was in the best interest of the corporation,
or in all  other  cases,  that his  conduct  was at  least  not  opposed  to the
corporation's best interest,  and (iii) in the case of criminal  proceedings the
individual had reasonable  cause to believe that his conduct was lawful,  or had
no reasonable  cause to believe that his conduct was unlawful.  The BCL provides
further that a corporation shall indemnify its directors,  officers,  employees,
and agents  who are  wholly  successful,  on the  merits or  otherwise,  against
expenses in the defense of such  proceedings.  The BCL provides,  however,  that
this indemnification should not be deemed exclusive of any other indemnification
rights provided by the Articles of Incorporation,  By-Laws,  resolution or other
authorizations  adopted by a majority  vote of the voting shares then issued and
outstanding.

           Under the same  statute,  an Indiana  corporation  may  purchase  and
maintain insurance on behalf of any person who is or was a director, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a  director,  officer,  employee or agent of another  enterprise  against any
liability  asserted  against him and  incurred by him in any such  capacity,  or
arising out of his status as such, whether or not the corporation would have the
power to indemnify him against such liability under the provisions of the BCL.

           Section  8.08,  Clause (b) of Article 8 of the Amended  and  Restated
Articles of Incorporation, as amended, of the Company provides as follows:

           Clause (b). Indemnification of Corporate Persons and Related Matters.
The following  provisions  apply to the  indemnification  by the  Corporation of
directors,  members  of any  committees  of the  Board of  Directors,  officers,
employees and agents of the Corporation  (collectively  "Corporate Persons") and
matters related thereto:


                                                        S-1





                  (i) Indemnification Standards. The Corporation shall indemnify
         any person who was or is a party or is threatened to be made a party to
         any  threatened,  pending  or  completed  action,  suit or  proceeding,
         whether civil or criminal,  administrative or investigative,  formal or
         informal  (an  "Action"),  by  reason  of the fact  that he is or was a
         Corporate Person of the Corporation or is or was serving at the request
         of the Corporation as a Corporate Person, partner, trustee or member or
         in another authorized capacity (collectively, an "Authorized Capacity")
         of or for another Legal Entity,  whether or not organized or formed for
         profit  (collectively,  "Another Entity"),  against expenses (including
         attorneys'  fees)  ("Expenses")  and  judgments,  penalties,  fines and
         amounts paid in settlement  actually and reasonably  incurred by him in
         connection  with such  Action,  if such person (1) acted in good faith,
         (2)  acted in a manner  he  reasonably  believed  (A) with  respect  to
         actions as a  Corporate  Person of the  Corporation,  to be in the best
         interests  of the  Corporation,  or (B) with  respect  to actions in an
         Authorized  Capacity of or for Another  Entity,  was not opposed to the
         best interests of the Corporation, and (3) with respect to any criminal
         Action,  either (A) had  reasonable  cause to believe  his  conduct was
         lawful,  or (B) had no  reasonable  cause to believe  his  conduct  was
         unlawful. The termination of any Action by judgment, order, settlement,
         conviction, or upon a plea of nolo contendere or its equivalent,  shall
         not,  of  itself,  be  determinative  that the  person did not meet the
         standards  for  indemnification  set forth in this  Clause  (b)(i) (the
         "Indemnification Standards").

                  (ii) Indemnification in Successfully  Defended Actions. To the
         extent  that  a  person  who  is  or  was a  Corporate  Person  of  the
         Corporation,  or is or was serving at the request of the Corporation in
         an Authorized Capacity of or for Another Entity, has been successful on
         the merits or  otherwise  in the  defense of any Action  referred to in
         Clause (b)(i) above, or in the defense of any claim, issue or matter in
         any such Action,  the Corporation  shall indemnify him against Expenses
         actually and reasonably incurred by him in connection therewith.

                  (iii)  Indemnification  Procedure.  Unless ordered by a court,
         any  indemnification  of any person under Clause  (b)(i) above shall be
         made by the Corporation  only as authorized in the specific case upon a
         determination  that  indemnification  of such  person  is proper in the
         circumstances  because  he  met  the  Indemnification  Standards.  Such
         determination  shall be made (1) by the Board,  by a majority vote of a
         quorum  consisting  of Directors who are not at the time parties to the
         Action  involved  ("Parties");  or (2) if a quorum  cannot be  obtained
         under  Subparagraph  (1),  by  a  majority  vote  of a  Committee  duly
         designated by the Board (in which designation Directors who are Parties
         may  participate),  consisting  solely of two or more Directors who are
         not at the time Parties; or (3) by written opinion of independent legal
         counsel (A) selected by the Board or Committee in the manner prescribed
         in Subparagraphs (1) or (2), respectively, or (B) if a quorum cannot be
         obtained and a Committee cannot be designated under  Subparagraphs  (1)
         and (2),  respectively,  selected by a majority  of the full Board,  in
         which selection  Directors who are Parties may  participate;  or (4) by
         the Shareholders who are not at the time Parties,  voting together as a
         single class.

                  (iv) Advances for Expenses.  Expenses  reasonably  incurred in
         defending   an  Action  by  any   person   who  may  be   entitled   to
         indemnification   under  Clause   (b)(i)  above  may  be  paid  by  the
         Corporation  in advance of the final  disposition of such Action if (1)
         such person furnishes the Corporation with (A) a written affirmation of
         his good faith belief that he has met,  and (B) a written  undertaking,
         executed  personally  or on  his  behalf,  to  repay  the  advance  (an
         "Undertaking") if it is ultimately determined that he did not meet, the
         Indemnification  Standards;  and (2) a determination is made, under the
         procedure set forth in Clause (b)(iii) above, that the facts then known
         to those making the  determination  would not preclude  indemnification
         under Clause (b)(i) above. An Undertaking must be an unlimited  general
         obligation  of the person making it, but need not be secured and may be
         accepted by the Corporation  without further reference to such person's
         financial ability to make repayment.

                  (v) Rights Not  Exclusive.  The  indemnification  provided  in
         these Articles (1) shall not be deemed exclusive of any other rights to
         which a person  seeking  indemnification  may be entitled under (A) any
         law,  (B)  the  By-Laws,  (C) any  resolution  of the  Board  or of the
         Shareholders, (D) any other

                                                        S-2





           authorization,  whenever adopted, after notice, by a majority vote of
           all Shares  entitled to vote on General  Voting  Matters,  or (E) the
           articles  of  incorporation,  code  of  by-laws  or  other  governing
           documents  or  any  resolution  of  or  other  authorization  by  the
           directors,  shareholders,  partners,  trustees,  members,  owners  or
           governing body, of Another Entity;  (2) shall inure to the benefit of
           the heirs, executors and administrators of such person; and (3) shall
           continue  as to any such  person  who has  ceased  to be a  Corporate
           Person of the Corporation or to be serving in an Authorized  Capacity
           for Another Entity.

               (vi) Insurance.  The Corporation shall have power to purchase and
           maintain  insurance on behalf of any person who is or was a Corporate
           Person of the Corporation, or is or was serving at the request of the
           Corporation  in an  Authorized  Capacity  of or for  Another  Entity,
           against any  liability  asserted  against and  incurred by him in any
           such capacity,  or arising out of his status as such,  whether or not
           the  Corporation  would have the power to indemnify  him against such
           liability under the provisions of this Clause (b).

              (vii)  Definition of Corporation.  For the purposes of this Clause
           (b),   references  to  "the  Corporation"   include  any  constituent
           corporation  absorbed in a consolidation or merger (a  "Constituent")
           as well as the resulting or surviving  corporation (the  "Survivor"),
           such  that any  person  who is or was a  Corporate  Person  of such a
           Constituent,  or is or was serving at the request of such Constituent
           in an Authorized  Capacity of or for Another  Entity,  shall stand in
           the same  position  under  the  provisions  of this  Clause  (b) with
           respect to the Survivor as he would if he had served the Survivor, or
           at his request, in the same capacity.

           The Company maintains  directors' and officers'  liability  insurance
with an annual  aggregate  limit of  $35,000,000  for the current policy period,
subject to a $200,000  deductible at the corporate  level, for each wrongful act
where  corporate  reimbursement  is available  to any director or officer.  When

Item 16.  List of Exhibits.

           The exhibits required by this item are listed on page E-1.

Item 17.  Undertakings.

           (a) The undersigned  registrant hereby undertakes (1) to file, during
any period in which offers or sales are being made, a  post-effective  amendment
to this registration statement (i) to include any prospectus required by Section
10(a)(3) of the  Securities  Act of 1933;  (ii) to reflect in the prospectus any
facts or events arising after the effective date of the  registration  statement
(or the most recent post-effective amendment thereof) which,  individually or in
the aggregate,  represent a fundamental  change in the  information set forth in
the registration  statement;  and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in the registration
statement  or any  material  change  to  such  information  in the  registration
statement; provided, however, that clauses (a)(1)(i) and (a)(1)(ii) do not apply
if the  information  required to be included in a  post-effective  amendment  by
those  clauses is contained in periodic  reports  filed with or furnished to the
Commission  by the  registrant  pursuant  to Section 13 or Section  15(d) of the
Securities  Exchange  Act of 1934  that are  incorporated  by  reference  in the
registration  statement;  (2) that, for the purpose of determining any liability
under the Securities Act of 1933,  each such  post-effective  amendment shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering  thereof;  and (3) to remove from registration by
means of a post-effective amendment any of the securities being registered which
remain unsold at the termination of the offering.


                                                        S-3





           (b) The undersigned  registrant  hereby undertakes that, for purposes
of determining  any liability  under the Securities Act of 1933,  each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

           (c) Insofar as  indemnification  for  liabilities  arising  under the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of the  registrant  pursuant to the provisions  described  under Item 15
above, or otherwise,  the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is,  therefore,  unenforceable.  In the event that a
claim for  indemnification  against such liabilities  (other than the payment by
the  registrant  of  expenses  incurred  or  paid  by  a  director,  officer  or
controlling  person of the registrant in the  successful  defense of any action,
suit or proceeding) is asserted by such director,  officer or controlling person
in connection with the securities being registered,  the registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
