                                    GENERAL

ITEM 1.  GENERAL INFORMATION

            (a)   Form of organization:  A CORPORATION
            (b)   State or other sovereign power under the laws of which
                  organized: DELAWARE

ITEM 2.  SECURITIES ACT EXEMPTION APPLICABLE.  State briefly the facts relied
         upon by the applicant as a basis for the claim that registration of
         the indenture securities under the Securities Act of 1933 is not
         required.

         The applicant is a debtor under Chapter 11 of Title 11 of the Code
(the "Bankruptcy Code").  The applicant has filed a plan of reorganization (the
"Plan") pursuant to Section 1125 of the Bankruptcy Code and the securities
being registered hereunder are being issued pursuant to the Plan to creditors
of the applicant.  Accordingly, registration of the indenture securities under
the Securities Act of 1933, as amended, is not required pursuant to Section
1145 of the Bankruptcy Code.

         Section 1145 of Title 11 of the United States Code (the "Bankruptcy
Code") exempts the original issuance of securities under the Plan from
registration under section 5 of the Securities Act of 1933 if three principal
requirements are satisfied; (i) the securities must be issued by the debtor or
its successors "under a plan" of reorganization, (ii) the recipients of the
securities must hold a claim against the debtor, an interest in the debtor or a
claim for an administrative expense against the debtor, and (iii) the
securities must be issued entirely in exchange for the recipient's claim
against or interest in the debtor, or "principally" in such exchange and
"partly" for cash or property.

         The applicant believes that the contemplated issuances of the
indenture securities will satisfy all three conditions because (i) those
issuances are specifically required under the provisions of the applicant's
Plan pursuant to which the indenture securities will be issued, (ii) the
recipients of such securities will be holders of claims against or interest in
the applicant, and (iii) the recipients will be issued the indenture securities
entirely in exchange for their claims or interests in the applicant.

ITEM 3.  AFFILIATES.   Furnish a list or diagram of all affiliates of the
         applicant and indicate the respective percentages of voting securities
         or other bases of control.  See Exhibit 1.

                              INDENTURE SECURITIES

ITEM 8.  ANALYSIS OF INDENTURE PROVISIONS.  Insert at this point the analysis
of indenture provisions required under Section 305(a)(2) of the Act.



                                     - 5 -
<PAGE>   6
         The Indenture contains the following Events of Default; (i) default in
payments of the Indenture Securities; (ii) failure to comply with covenants;
(iii) failure to discharge or otherwise provide for final, non-appealable
judgments for the payment of money exceeding $50 million in uninsured
liability; and (iv) certain events of insolvency with respect to the applicant;
all subject, as applicable, to customary grace periods (Article 5.01 of the
Indenture).  

        The holders of a majority in principal amount of Indenture Securities
outstanding may waive any past default under the Indenture with respect to such
securities, except a default not theretofore cured in the payment of the
principal of or interest on any Indenture Securities or in respect of any
provision which under the Indenture cannot be modified or amended without the
consent of the holder of each security affected (Article 5.04 of the
Indenture).

         Within 90 days after the Trustee becomes aware of the occurrence of any
default under the Indenture, the Trustee shall transmit by mail to all holders
of Indenture Securities notice of such default, unless such default shall have
been cured or waived; provided, however, that, except in the case of a default
in the payment of principal and interest on any Indenture Security (including
payments pursuant to the mandatory redemption provisions of such security), if
any, the Trustee shall be protected in withholding such notice so long as a
committee of its trust officers determines in good faith that the withholding
of such notice is in the interests of the holders of Indenture Securities. The
term "default" means any event which is, or after notice or lapse of time or
both, would become, an Event of Default with respect to Indenture Securities
(Section 6.05 of the Indenture).

         At any time and from time to time after the execution and delivery of 
the Indenture, the Applicant may execute and deliver Indenture Securities to the
Trustee for authentication, together with an order for the authentication and
delivery of such securities and the Trustee shall authenticate and deliver such
securities. The Indenture Securities are not valid until an authorized
signatory of the Trustee manually signs the certificate of authentication on
the security. Each Indenture Security shall be dated the date of its
authentication.

         Pursuant to the applicant's Plan of Reorganization, the Trustee, upon
receipt of a Company Order from the applicant, will authenticate the Indenture
Securities for original issue in an aggregate principal amount of up to $2.1
billion. These Indenture Securities are being issued to certain creditors of
the applicant in exchange for bankruptcy claims against the applicant pursuant
to the applicant's Plan of Reorganization. (See Section 2.03 of the Indenture).

         The Indenture Securities will be general senior obligations of the
applicant.  Therefore, there will be no property subject to lien under the
Indenture.

          When (i) the Applicant delivers to the Trustee all outstanding 
Securities (other than Securities replaced pursuant to Section 2.09 of
the Indenture) for cancellation or (ii) all outstanding Securities have become
due and payable and the Applicant irrevocably deposits with the Trustee funds
sufficient to pay at maturity all outstanding Securities, including interest
thereon (other than Securities replaced pursuant to Section 2.09 of the
Indenture), and if in either case the Applicant pays all other sums payable
hereunder by the Applicant, then this Indenture shall, except with respect to
certain continuing obligations of the Applicant under Section 7.01(c) of the
Indenture, cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Applicant
accompanied by an Officers' Certificate and an Opinion of Counsel (Section 7.01
of the Indenture). In addition, the applicant may, at any time, terminate (i)
all its obligations under the Indenture Securities and the Indenture ("Legal
Defeasance Option") or (ii) its obligations to comply with certain restrictive
covenants, provided that the applicant irrevocably deposits in trust with the
Indenture Trustee money or U.S. government obligations for the payment of
principal of and interest on the Indenture Securities to maturity or
redemption, as the case may be.  The conditions to defeasance shall be that (i)
no default exists or occurs, (ii) the applicant obtains a certificate from a
firm of nationally recognized independent accountants that the deposited U.S.
government obligations will be sufficient to pay principal of the interest on
the Indenture Securities to be defeased when due and (iii) in the case of the
Legal Defeasance Option, 91 days pass after the deposit is made and no event of
bankruptcy with respect to the applicant is continuing at the end of the 91-day
period (Sections 7.01 and 7.02 of the Indenture).






                                     - 6 -
<PAGE>   7

         The Applicant shall deliver to the Trustee within 120 days after the
end of each fiscal year of the Applicant a certificate from its principal
executive officer, principal financial officer or principal accounting officer
stating that in the course of the performance by such signer of his duties as
an officer of the Applicant he would normally have knowledge of any Default by
the Applicant or any noncompliance with the conditions and covenants under the
Indenture and whether or not he knows of any Default or any such noncompliance
that occurred during such period. If such officer does, the certificate shall
describe the Default or noncompliance, its status and what action the Applicant
is taking or proposes to take with respect thereto. (Section 3.05 of the
Indenture). The Indenture also requires the applicant to file with the Trustee
and the Commission, in accordance with rules and regulations prescribed from
time to time by the Commission, such information, documents and reports with
respect to compliance by the the applicant with the conditions and covenants
of the Indenture as may be required from time to time by such rules and
regulations (Section 3.02 of the Indenture).

securities. NOT APPLICABLE.

required by law, stock exchange rule, agreements to which the Company is
subject, if any, or usage (provided that any such notation, legend or
endorsement is in a form acceptable to the Company).

                    If any of the Terms of the series are established by action
taken pursuant to a Board Resolution, except as to those contemplated by the

                    SECTION 2.02.  Denominations.  The Securities of each
series shall be issuable in such denominations as shall be specified as
contemplated by Section 2.01.  In the absence of any such provisions with
respect to the Securities of any series, the Securities of such series shall be
issuable in denominations of $1,000 and in any integral multiple thereof.
Securities of each series shall be numbered, lettered or otherwise
distinguished in such manner in accordance with such plan as the Officers of
the Company executing the same may determine with the approval of the Trustee.

                    SECTION 2.03.  Execution, Authentication and Delivery.  One

signature.  The Company's seal shall be impressed, affixed, imprinted or
reproduced on the Securities and may be in facsimile form.

holds that office at the time the Trustee authenticates the Security, the
Security shall be valid nevertheless.

                    A Security shall not be valid until an authorized signatory
of the Trustee manually signs the certificate of authentication on the
Security.  The signature shall be conclusive evidence that the Security has
been authenticated under this Indenture.

                    At any time after the execution and delivery of this
Indenture, the Company may execute and deliver to the Trustee Securities of any
series, together with a Company Order for the authentication and delivery of
such Securities, and the Trustee in accordance with the Company Order shall
authenticate and deliver such Securities; provided that, if all Securities of a
series are not to be originally issued at one time, the Trustee shall
authenticate and deliver Securities of such series for original issue from time
to time in the aggregate Principal Amount established for such series pursuant
to such procedures acceptable to the Trustee and to such recipients as may be
specified from time to time by Company Order.  The maturity date, original
issuance date, interest rate and any other Terms of the Securities of such
series shall be determined by or pursuant to such Company Order and procedures.
If provided for in such procedures, such Company Order may authorize
authentication and delivery pursuant to oral or electronic instructions from
the Company or its duly authorized agents, which instructions, if given orally,
shall be promptly confirmed in writing.
<PAGE>   19
PAGE 18

                    If the forms or Terms of the Securities of the series have
been established by or pursuant to one or more Board Resolutions as permitted
by Section 2.01, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such
Securities, the Trustee shall be entitled to receive, and (subject to Section
6.01) shall be fully protected in relying upon, an Opinion of Counsel stating:

                    (a) that such forms and/or Terms have been established in
                 conformity with the provisions of this Indenture; and

                    (b) that such Securities, when authenticated and delivered
                 by the Trustee and issued by the Company in the manner and
                 subject to any conditions specified in such Opinion of
                 Counsel, will constitute valid and legally binding obligations
                 of the Company, entitled to the benefits of the Indenture and
                 enforceable against the Company in accordance with their
                 terms, subject to such exceptions as counsel may specify.

If such forms or Terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

                    Notwithstanding the provisions of Section 2.01 and of the
preceding paragraph, if all Securities of a series are not to be originally
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 2.01 or the Company Order
and Opinion of Counsel otherwise required pursuant to such preceding paragraph
at or prior to the time of authentication of each Security of such series if
such documents are delivered at or prior to the authentication upon original
issuance of the first Security of such series to be issued; provided that
paragraph (a) of said Opinion of Counsel shall, in such case, read as follows:

                    "(a)  that such forms have been established in conformity
                 with the provisions of this Indenture and the procedures for
                 determining the Terms of such Securities as set forth in the
                 procedures hereinabove referred to have been established in
                 conformity with the provisions of this Indenture."

                    If the Company shall establish pursuant to Section 2.01
that the Securities of a series are to be issued in whole or in part in the
form of a Global Security, then the Company shall execute and the Trustee shall
in accordance with this Section and the Company Order with respect to such
series authenticate and deliver the Global Security that (i) shall represent
and shall be denominated in an aggregate amount equal to the aggregate
principal amount of Outstanding Securities of such series to be represented by
the Global Security, (ii) shall be registered in the name of the Depository or
its nominee, and (iii) shall be delivered by the Trustee to such Depository or
pursuant to such Depository's instruction.
<PAGE>   20
PAGE 19

                    Each Depository designated pursuant to Section 2.01 for a
Global Security in registered form must, at the time of its designation and at
all times while it serves as Depository, be a clearing agency registered under
the Exchange Act and any other applicable statute or regulation.

                    SECTION 2.04.  Temporary Securities.  Pending the
preparation of definitive Securities of any series, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary
Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued, in registered
form and with such appropriate insertions, omissions, substitutions and other
variations as the Officers executing such Securities may determine, as
evidenced conclusively by their execution of such Securities.  Such temporary
Securities may be in global form.

                    If temporary Securities of any series are issued, the
Company will cause definitive Securities of that series to be prepared without
unreasonable delay.  After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company maintained pursuant to
Section 2.05 for the purpose of exchanges of Securities of such series, without
charge to the Holder.  Upon surrender for cancellation of any one or more
temporary Securities of any series the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like aggregate Principal
Amount of definitive Securities of the same series and of like tenor or
authorized denominations and having the same Terms and conditions.

                    Until exchanged in full as hereinabove provided, the
temporary Securities of any series shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities of the same series
and of like tenor authenticated and delivered hereunder.

                    SECTION 2.05.  Registrar and Paying Agent.  The Company
shall maintain an office or agency where Securities may be presented for
registration of transfer or for exchange (the "Registrar") and an office or
agency where Securities may be presented for payment (the "Paying Agent").  The
Registrar shall keep a register of the Securities and of their transfer and
exchange.  The Company may have one or more co-registrars and one or more
additional paying agents.  The term "Paying Agent" includes any additional
paying agent.

                    The Company shall enter into an appropriate agency
agreement with any Registrar, Paying Agent or co-registrar not a party to this
Indenture, which shall incorporate the terms of the TIA.  The agreement shall
implement the provisions of this Indenture that relate to such agent.  The
Company shall notify the Trustee of the name and address of any such agent.  If
the Company fails to maintain a Registrar or Paying Agent, the Trustee shall
act as such and shall be entitled to appropriate compensation therefor pursuant
to Section 6.07.  The Company or any
<PAGE>   21
PAGE 20

Subsidiary or Affiliate of the Company may act as Paying Agent, Registrar,
co-registrar or transfer agent.

                    The Company initially appoints the Trustee as Registrar and
Paying Agent in connection with the Securities.

                    SECTION 2.06.  Paying Agent To Hold Money in Trust.  On or
prior to each due date of the principal and interest on any Security, the
Company shall deposit with the Paying Agent a sum sufficient to pay such
principal and interest when so becoming due.  The Company shall require each
Paying Agent (other than the Trustee) to agree in writing that the Paying Agent
shall hold in trust for the benefit of Securityholders or the Trustee all money
held by the Paying Agent for the payment of principal of or interest on the
Securities and shall notify the Trustee of any default by the Company in making
any such payment.  If the Company or any Subsidiary or Affiliate of the Company
acts as Paying Agent, it shall segregate the money held by it as Paying Agent
and hold it as a separate trust fund.  The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and to account for any
funds disbursed by the Paying Agent.  Upon complying with this Section, the
Paying Agent shall have no further liability for the money delivered to the
Trustee.

                    SECTION 2.07.  Securityholder Lists.  The Trustee shall
preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Securityholders.  If the Trustee
is not the Registrar, the Company shall furnish to the Trustee, in writing at
least five Business Days before each May 15 and November 15 and at such other
times as the Trustee may request in writing, a list in such form and as of such
date as the Trustee may reasonably require of the names and addresses of
Securityholders.

                    SECTION 2.08.  Transfer and Exchange.  The Securities shall
be issued in registered form and shall be transferable only upon the surrender
of a Security with similar Terms of the same series for registration of
transfer.  When a Security is presented to the Registrar or a co-registrar with
a request to register a transfer, the Registrar shall register the transfer as
requested, subject to compliance with this paragraph.  When Securities of a
series are presented to the Registrar or a co-registrar with a request to
exchange them for an equal Principal Amount of Securities of such series with
similar Terms of other denominations, the Registrar shall make the exchange as
requested, subject to such compliance.  To permit registration of transfers and
exchanges, the Company shall execute and the Trustee shall authenticate
Securities of the applicable series with similar Terms at the Registrar's or
co-registrar's request.  The Company may require payment of a sum sufficient to
pay all taxes, assessments or other governmental charges.  Every Security
presented or surrendered for registration of transfer or for exchange shall (if
so required by the Company or the Trustee) be duly endorsed, or be accompanied
by a written instrument of transfer in form satisfactory to the Company and the
Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing.  The Company shall not be required (i) to Issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of
<PAGE>   22
PAGE 21

Securities of that series selected for redemption under Section 9.03 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

                    Prior to the due presentation for registration of transfer
of any Security, the Company, the Trustee, the Paying Agent, the Registrar or
any co-registrar may deem and treat the person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving
payment of principal of and interest on such Security and for all other
purposes whatsoever, whether or not such Security is overdue, and none of the
Company, the Trustee, the Paying Agent, the Registrar or any co-registrar shall
be affected by notice to the contrary.

                    If at any time the Depository for the whole or part of the
Securities of a series notifies the Company that it is unwilling or unable to
continue as Depository for such Securities or if at any time the Depository for
such Securities shall no longer be eligible under Section 2.03, the Company
shall appoint a successor Depository with respect to such Securities.  If a
successor Depository for such Securities is not appointed by the Company within
90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company's election pursuant to Section 2.01 shall no longer
be effective with respect to such Securities and the Company will execute, and
the Trustee, upon receipt of a Company Order for the authentication and
delivery of definitive Securities of such series, will authenticate and
deliver, corresponding Securities in definitive form in an aggregate principal
amount equal to the Principal Amount of the Global Security representing such
Securities in exchange for such Global Security.

                    If specified by the Company pursuant to Section 2.01 with
respect to a series of Securities, the Company may at any time and in its sole
discretion determine that Securities of any series issued in the form of one or
more Global Securities shall no longer be represented by such Global Security
or Securities.  In such event the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of corresponding
definitive Securities, will authenticate and deliver such Securities in
definitive form and in an aggregate Principal Amount equal to the Principal
Amount of such Global Security or Securities in exchange for such Global
Security or Securities.

                    If specified by the Company pursuant to Section 2.01 with
respect to the whole or part of a series of Securities, the Depository for such
Securities may surrender a Global Security for such Securities with similar
Terms in exchange in whole or in part for Securities of such series with
similar Terms in definitive form on such terms as are acceptable to the Company
and such Depository.  Thereupon, the Company shall execute, and the Trustee,
upon receipt of a Company Order for the authentication and delivery of
definitive Securities of such series with similar Terms, shall authenticate and
deliver, without charge to the Holders,
<PAGE>   23
PAGE 22

                    (i) to each person specified by such Depository a new
                 Security or Securities of the series with similar Terms of any
                 authorized denomination as requested by such person in
                 aggregate Principal Amount equal to and in exchange for such
                 person's beneficial interest in the Global Security; and

                    (ii) to such Depository a new Global Security in a
                 denomination equal to the difference, if any, between the
                 Principal Amount of the surrendered Global Security and the
                 aggregate Principal Amount of Securities with similar Terms
                 delivered to Holders thereof.

                    In any exchange provided for in any of the preceding three
paragraphs, the Company will execute and the Trustee will authenticate and
deliver Securities in definitive form in authorized denominations.

                    Upon the exchange of a Global Security for Securities in
definitive form, such Global Security shall be cancelled by the Trustee.
Securities issued in exchange for a Global Security pursuant to this Section
shall be registered in such names and in such authorized denominations as the
Depository for such Global Security, pursuant to instructions from its direct
or indirect participants or otherwise, shall instruct the Trustee.  The Trustee
shall deliver such Securities to the persons in whose names such Securities are
so registered.

                    Notwithstanding any other provision of this Section to the
contrary, unless and until a Global Security is exchanged in whole for
Securities in definitive form, a Global Security representing all or a portion
of the Securities of a series may not be transferred except as a whole by the
Depository for such series to a nominee of such Depository or by a nominee of
such Depository to such Depository or another nominee of such Depository or by
such Depository or any such nominee to a successor Depository for such series
or a nominee of such successor Depository.

                    SECTION 2.09.  Replacement Securities.  If a mutilated
Security is surrendered to the Registrar or if the Holder of a Security claims
that the Security has been lost, destroyed or wrongfully taken, the Company
shall Issue and the Trustee shall authenticate a replacement Security of the
applicable series with similar Terms if the Holder satisfies any other
reasonable requirements of the Trustee.  If required by the Trustee or the
Company, such Holder shall furnish evidence to their satisfaction of the
destruction, loss or wrongful taking of any Security so claimed to be lost,
destroyed or wrongfully taken, and an indemnity bond sufficient in the judgment
of the Company and the Trustee to protect the Company, the Trustee, the Paying
Agent, the Registrar and any co-registrar from any loss which any of them may
suffer if a Security is replaced.  The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

                    Every replacement Security is an additional obligation of
the Company.
<PAGE>   24
PAGE 23

                    SECTION 2.10.  Outstanding Securities.  Securities
outstanding at any time are all Securities authenticated by the Trustee except
for those cancelled by it, those delivered to it for cancellation and those
described in this Section as not outstanding.  A Security does not cease to be
outstanding because the Company or an Affiliate of the Company holds the
Security.

                    If a Security is replaced pursuant to Section 2.09, it
ceases to be outstanding unless the Trustee and the Company receive proof
satisfactory to them that the replaced Security is held by a bona fide
purchaser.

                    If the Paying Agent segregates and holds in trust, in
accordance with this Indenture, on a redemption date or maturity date money
sufficient to pay all principal, premium (if applicable) and interest payable
on that date with respect to the Securities to be redeemed or maturing, as the
case may be, and the Paying Agent is not prohibited from paying such money to
the Securityholders on that date pursuant to the terms of this Indenture, then
on and after that date such Securities cease to be outstanding and interest on
them ceases to accrue.

                    In determining whether the Holders of the requisite
Principal Amount of outstanding Securities have given any request, demand,
authorization, direction, notice, consent or waiver hereunder the Principal
Amount of an Original Issue Discount Security that shall be deemed to be
outstanding for such purposes shall be the amount of the principal thereof that
would be due and payable as of the date of such determination upon a
declaration of acceleration of the maturity thereof pursuant to Section 5.02.

                    SECTION 2.11.  Cancellation.  The Company at any time may
deliver Securities to the Trustee for cancellation.  The Registrar and the
Paying Agent shall forward to the Trustee any Securities surrendered to them
for registration of transfer, exchange or payment.  The Trustee and no one else
shall cancel and destroy (subject to the record retention requirements of the
Exchange Act) all Securities surrendered for registration of transfer,
exchange, payment or cancellation and deliver a certificate of such destruction
to the Company unless the Company directs the Trustee to deliver cancelled
Securities to the Company.  The Company may not Issue new Securities to replace
Securities it has redeemed, paid or delivered to the Trustee for cancellation.

                    SECTION 2.12.  Default Interest.  If the Company defaults
in a payment of interest on the Securities, the Company shall pay defaulted
interest (plus interest on such defaulted interest to the extent lawful at the
rate or rates prescribed therefor in the Securities) in any lawful manner.  The
Company may also pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date, which date shall be at
least five Business Days prior to the payment date in which case the Company
shall fix or cause to be fixed any such special record date and payment date,
and, at least 15 days before any such special record date, the Company shall
mail to each Securityholder a notice that states the special record date, the
payment date and the amount of defaulted interest to be paid.

                                   Covenants

                    SECTION 3.01.  Payment of Securities.  The Company shall
promptly pay the principal of and interest on the Securities on the dates and
in the manner provided in the Securities and in this Indenture.  Principal and
interest shall be considered paid on the date due if on such date the Trustee
or the Paying Agent holds in accordance with this Indenture money sufficient to
pay all principal and interest then due and the Trustee or the Paying Agent, as
the case may be, is not prohibited from paying such money to the
Securityholders on that date pursuant to the terms of this Indenture.

                    SECTION 3.02.  SEC Reports.  The Company shall file with
the Trustee, within 30 days after it files them with the SEC, copies of its
annual report and of the information, documents and other reports (or copies of
such portions of any of the foregoing as the SEC may by rules and regulations
prescribe) which the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act.  The Company shall also comply with
the other provisions of TIA Section 314(a)(1),(2) and (3).

                    SECTION 3.03.  Limitation on Secured Debt.  The Company
shall not issue any Secured Debt unless contemporaneously therewith effective
provision is made to secure the Securities equally and ratably with such
Secured Debt for so long as such Secured Debt is secured by a Lien. The
preceding sentence shall not require the Company to equally and ratably secure
the Securities upon the incurrence of the following Secured Debt:

                    (1) Debt of the Company which is incurred to finance the
                 acquisition, construction or improvement of assets of the
                 Company and its Subsidiaries, which acquisition is
                 consummated, or which construction or improvement is
                 commenced, after the date of this Indenture; provided,
                 however, that such Debt shall not be secured by any assets of
                 the Company other than assets so acquired, constructed or
                 improved (together with (i) to the extent the terms of Secured
                 Debt so provides, repairs and additions thereto and
                 improvements thereof, and (ii) with respect to construction
                 and improvement, if any theretofore unimproved real property on
                 which the property so constructed or improved is located);

                    (2) Debt of the Company which is secured by assets of a
                 person where such Debt was existing at the time such person
                 was merged or consolidated with the Company or at the time of
                 sale, other disposition, or lease, of the properties of such
                 person as an entirety (or substantially as an entirety) to the
                 Company; provided, however, that such Debt shall not be
                 secured by any assets of the Company other than the assets
                 subject thereto at the time of the acquisition (together with,
                 to the extent the terms of Secured Debt so provides, repairs
                 and additions thereto and improvements thereof);
<PAGE>   26
PAGE 25

                    (3) Debt of the Company issued to refinance such Debt
                 incurred under paragraphs (1) and (2) provided that the Debt
                 so issued is not secured by a Lien on assets other than those
                 which secure the Debt being refinanced (together with, to the
                 extent the terms of new Secured Debt so provides, repairs and
                 additions thereto and improvements thereof);

                    (4) Debt of the Company which is secured by inventory,
                 accounts receivable, or customers' installment paper including
                 by means of asset securitizations;

                    (5) Obligations arising with respect to Production 
                 Payments; and

                    (6) Other Debt with a Principal Amount not exceeding, in
                 the aggregate at any one time outstanding, ten percent (10%)
                 of the Consolidated Tangible Assets of the Company and its
                 consolidated subsidiaries, as of the end of the most recent
                 fiscal quarter of the Company ending not less than 45 days
                 from the date of determination.

                    The term "Consolidated Tangible Assets" means that sum of
                 the Tangible Assets of the Company and its consolidated
                 Subsidiaries after eliminating intercompany items.

                    The term "Tangible Assets", as applied to any person on any
                 date shall mean the gross book value as shown on the books of
                 such person of all its property both real and personal
                 (exclusive of licenses, patents, patent applications,
                 copyrights, trademarks, trade names, good will, experimental
                 or organizational expense and other like intangibles, treasury
                 stock and unamortized debt discount and expense but including
                 regulatory assets properly recorded on the balance sheet of
                 such person.)

                    SECTION 3.04.  Limitations on Funded Debt of Significant
Subsidiaries.  The Company shall not permit any Significant Subsidiary to
issue, directly or indirectly, any Funded Debt except:

                    (1)  Funded Debt issued and outstanding on or prior to the
                 date of this Indenture;

                    (2) Funded Debt issued to and held by the Company or a
                 Subsidiary; provided, however, that any subsequent issuance or
                 transfer of any common stock which results in any such
                 Subsidiary ceasing to be a Subsidiary and any subsequent
                 transfer of such Debt (other than to the Company or a
                 Subsidiary) shall be deemed the issuance of such Debt by the
                 issuer thereof;

                    (3) Funded Debt of a Significant Subsidiary issued and
                 outstanding on or prior to the date on which such Subsidiary
                 was acquired by the Company or on which it became a
                 Significant Subsidiary;
<PAGE>   27
PAGE 26

                    (4) Funded Debt issued to finance the acquisition by such
                 Significant Subsidiary of any assets or Capital Stock of any
                 person or the construction or improvement of assets of such
                 Significant Subsidiary, which acquisition is consummated, or
                 which construction or improvement is commenced, after the date
                 of this Indenture;

                    (5) Funded Debt issued in exchange for, or the proceeds of
                 which are used to refund or refinance, Debt referred to in the
                 foregoing clauses (1) through (4) or to reacquire equity of
                 such Significant Subsidiary held by the Company or a
                 Subsidiary;

                    (6) Funded Debt issued with respect to (a) obligations that
                 are tax-exempt pursuant to Section 103 of the Internal Revenue
                 Code of 1986 as from time to time amended and that are issued
                 in connection with pollution control or other facilities of
                 such Significant Subsidiary or (b) other obligations, whether
                 taxable to tax-exempt, that are issued through any public or
                 governmental authority in connection with pollution control or
                 other facilities of such Significant Subsidiary;

                    (7) Funded Debt in an aggregate amount not exceeding the
                 sum of (a) total inventory of the Significant Subsidiary; (b)
                 total accounts receivable of the Significant Subsidiary; and
                 (c) the total amount of customers' installment paper of such
                 Significant Subsidiary, in accordance with generally accepted
                 accounting principles, in each case, as of the end of the most
                 recent fiscal quarter of such Significant Subsidiary ending
                 not less than 45 days from the date of determination;

                    (8) Obligations with respect to Production Payments; and

                    (9) Funded Debt in an aggregate Principal Amount which,
                 when added to the aggregate Principal Amount of Funded Debt of
                 all other Significant Subsidiaries (other than Funded Debt
                 referred to in clauses (1) through (8) above) does not exceed,
                 at any one time outstanding, ten percent (10%) of the sum of
                 the Tangible Assets of such Significant Subsidiary and all
                 other Significant Subsidiaries determined on a consolidated
                 basis, as of the end of the most recent fiscal quarter of each
                 such Significant Subsidiary ending not less than 45 days from
                 the date of determination.

                    SECTION 3.05.  Compliance Certificate.  The Company shall
deliver to the Trustee within 120 days after the end of each fiscal year of the
Company a certificate from its principal executive officer, principal 
financial officer or principal accounting officer stating that in the course 
of the performance by such signer of his duties as an officer of the Company 
he would normally have knowledge of any Default by the Company or any 
noncompliance with the conditions and covenants under the Indenture and 
whether or not he knows of any Default or any such noncompliance that occurred 
during such period.  If such officer does, the certificate shall describe the 
Default or non-compliance, its status and what action the Company is taking or 
proposes to take with respect thereto.  For purposes of this Section 3.05, 
such noncompliance
<PAGE>   28

shall be determined without regard to any period of grace or requirement of
notice provided under this Indenture.

                               Successor Company

                    SECTION 4.01.  When Company May Merge or Transfer Assets.
The Company shall not consolidate with or merge with or into, or convey or
otherwise transfer, or lease, its assets as an entirety (or substantially as an
entirety) to, any person, unless:

                    (i) the resulting, surviving or transferee person (if not
                 the Company) shall be a person organized and existing under
                 the laws of the United States of America, any State thereof or
                 the District of Columbia and shall expressly assume, by an
                 indenture supplemental hereto, executed and delivered to the
                 Trustee, in form reasonably satisfactory to the Trustee, all
                 the obligations of the Company under the Securities and this
                 Indenture;

                    (ii) immediately after giving effect to such transaction
                 (and treating any Debt, other than Debt referred to in clause
                 (2) of Section 3.03, which becomes an obligation of the
                 resulting, surviving or transferee person as a result of such
                 transaction as having been incurred by such person at the time
                 of such transaction and, in the case of Debt of the type
                 described in clause (1) of Section 3.03, the relevant
                 acquisition, construction or improvement as having then
                 occurred no Default shall have happened and be continuing; and

                    (iii) the Company shall have delivered to the Trustee an
                 Officers' Certificate and an Opinion of Counsel, each stating
                 that such consolidation, merger, transfer, or lease and such
                 supplemental indenture (if any) comply with this Indenture.

                    SECTION 4.02.  Successor Entity Substituted.  Upon any
consolidation by the Company with or merger by the Company into any other
entity or any conveyance or other transfer, or lease, of the assets of the
Company as an entirety (or substantially as an entirety) in accordance with
Section 4.01, the successor entity formed by such consolidation or into which
the Company is merged or to which such conveyance or other transfer, or lease,
is made shall succeed to, and be substituted for, and may exercise every right
and power of, the Company under this Indenture with the same effect as if such
successor entity had been named as the Company herein, and thereafter, except
in the case of a lease, the predecessor entity shall be relieved of all
obligations and covenants under this Indenture and the Securities.

                             Defaults and Remedies

                    SECTION 5.01.  Events of Default.  An "Event of Default"
occurs if:

                    (1) the Company defaults in any payment of interest on any
                 Security when the same becomes due and payable and such
                 default continues for a period of 30 days;

                    (2) the Company defaults in the payment of the principal of
                 any Security when the same becomes due and payable at its
                 stated maturity, upon declaration or otherwise;

                    (3) the Company fails to comply with Section 4.01;

                    (4) the Company fails to comply with any of its agreements
                 in the Securities or this Indenture (other than those referred
                 to in (1), (2), or (3) above) and such failure continues for
                 60 days after the notice specified below;

                    (5) the Company pursuant to or within the meaning of any
                 Bankruptcy Law:

                          (A) commences a voluntary case;

                          (B) consents to the entry of an order for relief
                    against it in an involuntary case;

                          (C) consents to the appointment of a Custodian of it
                    or for any substantial part of its property; or

                          (D) makes a general assignment for the benefit of its
                    creditors; or

                    (6) a court of competent jurisdiction enters an order or
                 decree under any Bankruptcy Law that:

                          (A) is for relief against the Company in an
                    involuntary case;

                          (B) appoints a Custodian of the Company or for any
                    substantial part of its property; or

                          (C) orders the winding up or liquidation of the
                    Company;

                 and the order or decree remains unstayed and in effect for 60
                 days.

                    The term "Bankruptcy Law" means Title 11, United States
Code, or any similar Federal or state law for the relief of debtors.  The term

similar official under any Bankruptcy Law.

                    A Default under clause (4) is not an Event of Default until
the Trustee or the Holders of at least 25% in principal amount of the
Securities notify the Company of the Default and the Company does not cure such
Default within the time specified after receipt of such Notice.  Such Notice
must specify the Default, demand that it be remedied and state that such notice
is a "Notice of Default".

                    The Company shall deliver to the Trustee, within 30 days
after the occurrence thereof, written notice in the form of an Officers'
Certificate of any event which with the giving of notice and the lapse of time
would become an Event of Default under clause (4), its status and what action
the Company is taking or proposes to take with respect thereto.

                    SECTION 5.02.  Acceleration.  If an Event of Default (other
than an Event of Default specified in Section 5.01(5) or (6)) occurs and is
continuing, the Trustee by notice to the Company, or the Holders of at least
25% in principal amount of the Securities by notice to the Company and the
Trustee, may declare the principal of (or, in connection with Original Issue
Discount Securities, such portion of the principal amount as may be specified
in the terms of such Securities) and accrued interest on all the Securities to
be due and payable.  Upon such a declaration, such principal (or portion
thereof) and interest shall be due and payable immediately.  If an Event of
Default specified in Section 5.01(5) or (6) occurs and is continuing, the
principal of and interest on all the Securities shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Securityholders.  If all existing Events of Default have
been cured or waived, except nonpayment of principal or interest that has
become due solely because of acceleration, any such acceleration and its
consequences shall be automatically rescinded unless such rescission would
conflict with any judgment or decree.   No such rescission shall affect any
subsequent Default or impair any right consequent thereto.

                    SECTION 5.03.  Other Remedies.  If an Event of Default
occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of principal of or interest on the Securities or to enforce
the performance of any provision of the Securities or this Indenture.

                    The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the
proceeding.  A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default.  No remedy is exclusive of any other remedy.  All available
remedies are cumulative.

                    SECTION 5.04.  Waiver of Past Defaults.  The Holders of a
majority in principal amount of the Securities by notice to the Trustee may
waive an existing Default and its consequences except (1) a Default in the
payment of the principal of or interest on a Security or (2) a Default in
respect of a provision that under Section 8.02 cannot be amended without the
<PAGE>   31
PAGE 30

consent of each Securityholder affected.  When a Default is waived, it is
deemed cured, but no such waiver shall extend to any subsequent or other
Default or impair any consequent right.

                    SECTION 5.05.  Control by Majority.  The Holders of a
majority in Principal Amount of the Securities may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
of exercising any trust or power conferred on the Trustee.  However, the
Trustee may refuse to follow any direction that conflicts with law or this
Indenture or, subject to Section 6.01, that the Trustee determines is unduly
prejudicial to the rights of other Securityholders or would involve the Trustee
in personal liability; provided, however, that the Trustee may take any other
action deemed proper by the Trustee that is not inconsistent with such
direction.  Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

                    SECTION 5.06.  Limitation on Suits.  A Securityholder may
not pursue any remedy with respect to this Indenture or the Securities unless:

                    (1) the Holder gives to the Trustee written notice stating
                 that an Event of Default is continuing;

                    (2) the Holders of at least 25% in Principal Amount of the
                 Securities make a written request to the Trustee to pursue the
                 remedy;

                    (3) such Holder or Holders offer to the Trustee reasonable
                 security or indemnity against any loss, liability or expense;

                    (4) the Trustee does not comply with the request within 60
                 days after receipt of the request and the offer of security or
                 indemnity; and

                    (5) the Holders of a majority of Principal Amount of the
                 Securities do not give the Trustee a direction inconsistent
                 with the request during such 60-day period.

                    A Securityholder may not use this Indenture to prejudice
the rights of another Securityholder or to obtain a preference or priority over
another Securityholder.

                    SECTION 5.07.  Rights of Holders To Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of principal of and interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Securities, or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

                    SECTION 5.08.  Collection Suit by Trustee.  If an Event of
Default in payment of interest or principal specified in Section 5.01(1) or (2)
occurs and is continuing, the Trustee
<PAGE>   32
PAGE 31

may recover judgment in its own name and as trustee of an express trust against
the Company for the whole amount of principal and interest remaining unpaid
(together with interest on such unpaid interest as provided in Section 3.01, to
the extent lawful) and the amounts provided for in Section 6.07.

                    SECTION 5.09.  Trustee May File Proofs of Claim.  The
Trustee may file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee and the
Securityholders allowed in any judicial proceedings relative to the Company,
its creditors or its property and, unless prohibited by law or applicable
regulations, may vote on behalf of the Holders in any election of a trustee in
bankruptcy or other person performing similar functions, and any Custodian in
any such judicial proceeding is hereby authorized by each Holder to make
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section  6.07.

                    SECTION 5.10.  Priorities.  If the Trustee collects any
money pursuant to this Article 5, it shall pay out the money in the following
order:

                    FIRST:  to the Trustee for amounts due under Section 6.07;

                    SECOND:  to Securityholders for amounts due and unpaid on
                 the Securities for principal and interest, ratably, without
                 preference or priority of any kind, according to the amounts
                 due and payable on the Securities for principal and interest,
                 respectively; and

                    THIRD:  to the Company.

                    The Trustee may fix a record date and payment date for any
payment to Securityholders pursuant to this Section.  At least 15 days before
such record date, the Company shall mail to each Securityholder and the Trustee
a notice that states the record date, the payment date and amount to be paid.

                    SECTION 5.11.  Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any
party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant.  This Section does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 5.07 or a suit
by Holders of more than 10% in Principal Amount of the Securities.

                    SECTION 5.12.  Waiver of Stay or Extension Laws.  The
Company (to the extent it may lawfully do so) shall not at any time insist
upon, or plead, or in any manner whatsoever
<PAGE>   33
PAGE 32

claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any
such law, and shall not hinder, delay or impede the execution of any power
herein granted to the Trustee, but shall suffer and permit the execution of
every such power as though no such law had been enacted.


                                   ARTICLE 6

                                    Trustee

                    SECTION 6.01.  Duties of Trustee.  (a)  If an Event of
Default has occurred and is continuing, the Trustee shall exercise the rights
and powers vested in it by this Indenture and use the same degree of care and
skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.

                    (b)  Except during the continuance of an Event of Default:

                    (1) the Trustee undertakes to perform such duties and only
                 such duties as are specifically set forth in this Indenture
                 and no implied covenants or obligations shall be read into
                 this Indenture against the Trustee; and

                    (2) in the absence of bad faith on its part, the Trustee
                 may conclusively rely, as to the truth of the statements and
                 the correctness of the opinions expressed therein, upon
                 certificates or opinions furnished to the Trustee and
                 conforming to the requirements of this Indenture.  However,
                 the Trustee shall examine the certificates and opinions to
                 determine whether or not they conform to the requirements of
                 this Indenture.

                    (c)  The Trustee may not be relieved from liability for its
own negligent action, its own negligent failure to act or its own wilful
misconduct, except that:

                    (1) this paragraph does not limit the effect of paragraph
                 (b) of this Section;

                    (2) the Trustee shall not be liable for any error of
                 judgment made in good faith by a Trust Officer unless it is
                 proved that the Trustee was negligent in ascertaining the
                 pertinent facts; and

                    (3) the Trustee shall not be liable with respect to any
                 action it takes or omits to take in good faith in accordance
                 with a direction received by it pursuant to Section 5.05.

                    (d)  Every provision of this Indenture that in any way
relates to the Trustee is subject to paragraphs (a), (b) and (c) of this
Section.
<PAGE>   34
PAGE 33

                    (e)  The Trustee shall not be liable for interest on any
money received by it except as the Trustee may agree in writing with the
Company.

                    (f)  Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by law.

                    (g)  No provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur financial liability
in the performance of any of its duties hereunder or in the exercise of any of
its rights or powers, if it shall have reasonable grounds to believe that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

                    (h)  Every provision of this Indenture relating to the
conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Section and to the provisions of the
TIA.

                    SECTION 6.02.  Rights of Trustee.  (a)  The Trustee may
rely on any document believed by it to be genuine and to have been signed or
presented by the proper person.  The Trustee need not investigate any fact or
matter stated in the document.

                    (b)  Before the Trustee acts or refrains from acting, it
may require an Officers' Certificate or an Opinion of Counsel.  The Trustee
shall not be liable for any action it takes or omits to take in good faith in
reliance on the Officers' Certificate or Opinion of Counsel, subject to Section
6.02(e).

                    (c)  The Trustee may act through agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care.

                    (d)  The Trustee shall not be liable for any action it
takes or omits to take in good faith which it believes to be authorized or
within its rights or powers.

                    (e)  The Trustee may consult with counsel, and the advice
or opinion of counsel with respect to legal matters relating to this Indenture
and the Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder
in good faith and in accordance with the advice or opinion of such counsel.

                    SECTION 6.03.  Individual Rights of Trustee.  The Trustee
in its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with the Company or its affiliates with the
same rights it would have if it were not Trustee.  Any Paying Agent, Registrar,
co-registrar or co-paying agent may do the same with like rights.  However, the
Trustee must comply with Sections 6.10 and 6.11.
<PAGE>   35
PAGE 34

                    SECTION 6.04.  Trustee's Disclaimer.  The Trustee shall not
be responsible for and makes no representation as to the validity or adequacy
of this Indenture or the Securities, it shall not be accountable for the
Company's use of the proceeds from the Securities, and it shall not be
responsible for any statement of the Company in the Indenture or in any
document issued in connection with the sale of the Securities or in the
Securities other than the Trustee's certificate of authentication.

                    SECTION 6.05.  Notice of Defaults.  If a Default occurs and
is continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within 90 days after it occurs.  Except in
the case of a Default in payment of principal of or interest on any Security
(including payments pursuant to the mandatory redemption provisions of such
Security), the Trustee may withhold the notice if and so long as a committee of
its Trust Officers in good faith determines that withholding the notice is in
the interests of Securityholders.

                    SECTION 6.06.  Reports by Trustee to Holders.  Prior to
November 1 in each year, the Trustee shall mail to each Securityholder a brief
report dated as of the preceding September 1 that complies with TIA Section
313(a), if so required by such Section of the TIA.  The Trustee also shall
comply with TIA Section 313(b).

                    A copy of each report at the time of its mailing to
Securityholders shall be filed with the SEC and each stock exchange on which
the Securities are listed.  The Company agrees to notify promptly the Trustee
whenever the Securities become listed on any stock exchange and of any
delisting thereof.

                    SECTION 6.07.  Compensation and Indemnity.  The Company
shall pay to the Trustee from time to time reasonable compensation for its
services, including those arising in the Trustee's performance of its duties
under Sections 5.02, 5.03 and 5.08 hereof, and to the extent permitted by law,
Section 5.09 hereof.  The Trustee's compensation shall not be limited by any 
law on compensation of a trustee of an express trust.  The Company shall 
reimburse the Trustee upon request for all reasonable out-of-pocket expenses 
incurred or made by it, including costs of collection, in addition to the 
compensation for its services.  Such expenses shall include the reasonable 
compensation and expenses, disbursements and advances of the Trustee's agents, 
counsel, accountants and experts.  The Company shall indemnify the Trustee 
against any and all loss, liability or expense (including attorneys' fees) 
incurred by it in connection with the administration of this trust and the 
performance of its duties hereunder.  The Trustee shall notify the Company 
promptly of any claim for which it believes it may seek indemnity.  Failure by 
the Trustee to so notify the Company shall not relieve the Company of its 
obligations hereunder. The Company shall defend the claim and the Trustee may 
have separate counsel and the Company shall pay the reasonable fees and 
expenses of such counsel. The Company need not reimburse any expense or 
indemnify against any loss, liability or expense to the extent incurred by the 
Trustee through the Trustee's own willful misconduct, negligence or bad faith.
<PAGE>   36
PAGE 35

                    To secure the Company's payment obligations in this
Section, the Trustee shall have a Lien prior to the Securities on all money or
property held or collected by the Trustee, except that held in trust to pay
principal of and interest on particular Securities.

                    The Company's payment obligations pursuant to this Section
shall survive the discharge of this Indenture.


                    For purposes of this Section, the term "Trustee" shall
include any predecessor Trustee, provided that any Trustee hereunder shall not
be liable for the willful misconduct, negligence or bad faith of any other
Trustee hereunder.

                    SECTION 6.08.  Replacement of Trustee.  The Trustee may
resign at any time by so notifying the Company.  The Holders of a majority in
Principal Amount of the Securities may remove the Trustee by so notifying the
Trustee and may appoint a successor Trustee.  The Company shall remove the
Trustee if:

                    (1) the Trustee fails to comply with Section 6.10;

                    (2) the Trustee is adjudged bankrupt or insolvent;

                    (3) a receiver or other public officer takes charge of the
                 Trustee or its property; or

                    (4) the Trustee otherwise becomes incapable of acting.

                    If the Trustee resigns or is removed or if a vacancy exists
in the office of Trustee for any reason (the Trustee in such event being
referred to herein as the retiring Trustee), the Company shall promptly appoint
a successor Trustee.

                    A successor Trustee shall deliver a written acceptance of
its appointment to the retiring Trustee and to the Company.  Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture.  The successor Trustee shall mail a notice of its
succession to Securityholders.  The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, subject to the
Lien provided for in Section 6.07.

                    If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of a majority in Principal Amount of the Securities may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.
<PAGE>   37
PAGE 36

                    If the Trustee fails to comply with Section 6.10, any
Securityholder (subject to compliance with TIA Section 310(b)(iii)) may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

                    Notwithstanding the replacement of the Trustee pursuant to
this Section, the Company's obligations under Section 6.07 shall continue for
the benefit of the retiring Trustee.

                    SECTION 6.09.  Successor Trustee by Merger.  If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

                    In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of
the successor to the Trustee; and in all such cases such certificates shall
have the full force which it is anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have.

                    SECTION 6.10.  Eligibility; Disqualification.  The Trustee
shall at all times satisfy the requirements of TIA Section 310(a).  The
Trustee shall have a combined capital and surplus of at least $50,000,000 as
set forth in its most recent published annual report.  The Trustee shall comply
with TIA Section 310(b).

                    SECTION 6.11.  Preferential Collection of Claims Against
Company.  The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b).  A Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated.

                       Discharge of Indenture; Defeasance

                    SECTION 7.01.  Discharge of Liability on Securities;
Defeasance.  (a)  When (i) the Company delivers to the Trustee all outstanding
Securities (other than Securities replaced pursuant to Section 2.09) for
cancellation or (ii) all outstanding Securities have become due and payable and
the Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity all outstanding Securities, including interest thereon (other than
Securities replaced pursuant to Section 2.09), and if in either case the
Company pays all other sums payable hereunder by the
<PAGE>   38
PAGE 37

Company, then this Indenture shall, subject to Section 7.01(c), cease to be of
further effect.  The Trustee shall acknowledge satisfaction and discharge of
this Indenture on demand of the Company accompanied by an Officers' Certificate
and an Opinion of Counsel.

                    (b)  Subject to Sections 7.01(c) and 7.02, the Company at
any time may terminate (i) all its obligations under this Indenture with
respect to the Securities of a series ("Legal Defeasance Option") or (ii) its
obligations under Sections 3.03 and 3.04 and the operation of Section 5.01(4)
("Covenant Defeasance Option") with respect to a series of Securities.  The
Company may exercise its Legal Defeasance Option notwithstanding its prior
exercise of its Covenant Defeasance Option.

                    If the Company exercises its Legal Defeasance Option,
payment of the Securities of such series may not be accelerated because of an
Event of Default.  If the Company exercises its Covenant Defeasance Option,
payment of the Securities of such series may not be accelerated because of an
Event of Default specified in Section 5.01(4).

                    Upon satisfaction of the conditions set forth herein and
upon request of the Company, the Trustee shall acknowledge in writing the
discharge of those obligations that the Company terminates.

                    (c)  Notwithstanding clauses (a) and (b) above, the
Company's obligations with respect to such series in Sections 2.05, 2.06, 2.07,
2.08, 2.09, 6.07, 6.08, 7.03 and 7.04 shall survive until the Securities of
such series have been paid in full.  Thereafter, the Company's obligations in
Sections 6.07 and 7.04 with respect to such series shall survive.

                    SECTION 7.02.  Conditions to Defeasance.  The Company may
exercise its Legal Defeasance Option or its Covenant Defeasance Option only if:

                    (1) the Company irrevocably deposits in trust with the
                 Trustee money or U.S. Government Obligations for the payment
                 of principal and interest on the Securities of the series to
                 be defeased to maturity or redemption, as the case may be;

                    (2) the Company delivers to the Trustee a certificate from
                 a nationally recognized firm of independent accountants
                 expressing its opinion that the payments of principal and
                 interest when due and without reinvestment on the deposited
                 U.S. Government Obligations plus any deposited money without
                 investment will provide cash at such times and in such amounts
                 (but, in the case of the Legal Defeasance Option only, not
                 more than such amounts) as will be sufficient to pay principal
                 and interest when due on all the Securities of such series to
                 maturity or redemption, as the case may be;

                    (3) in the case of the Legal Defeasance Option, 91 days
                 pass after the deposit is made and during the 91-day period
                 no Default specified in Section 5.01(5) or (6) occurs which is
                 continuing at the end of the period;
<PAGE>   39
PAGE 38

                    (4) no Default has occurred and is continuing on the date
                 of such deposit and after giving effect thereto; and

                    (5) the Company delivers to the Trustee an Officers'
                 Certificate and an Opinion of Counsel, each stating that all
                 conditions precedent to the defeasance and discharge of the
                 Securities of such series as contemplated by this Article 7
                 have been complied with.

                    Before or after a deposit, the Company may make
arrangements satisfactory to the Trustee for the redemption of Securities at a
future date in accordance with Article 9.

                    SECTION 7.03.  Application of Trust Money.  The Trustee
shall hold in trust money or U.S. Government Obligations deposited with it
pursuant to this Article 7.  It shall apply the deposited money and the money
from U.S.  Government Obligations through the Paying Agent and in accordance
with this Indenture to the payment of principal of and interest on the relevant
Securities.

                    SECTION 7.04.  Repayment to Company.  The Trustee and the
Paying Agent shall promptly turn over to the Company upon request any excess
money or securities held by them at any time not required for the payment of
the Securities.

                    With respect to the money or securities held under Sections
7.01 and 7.02, in determining whether such money or securities are excess, the
Trustee may rely on the certificate provided to it under Section 7.02(2).

                    Subject to any applicable abandoned property law, the
Trustee and the Paying Agent shall pay to the Company upon request any money
held by them for the payment of principal or interest that remains unclaimed
for two years, and, thereafter, Securityholders entitled to the money must look
to the Company for payment as general creditors.


                                   ARTICLE 8

                                   Amendments

                    SECTION 8.01.  Without Consent of Holders.  The Company and
the Trustee may amend this Indenture or the Securities without notice to or
consent of any Securityholder:

                    (1) to cure any ambiguity, omission, defect or
                 inconsistency;

                    (2) to comply with Article 4;

                    (3) to provide for uncertificated Securities in addition to
                 or in place of certificated Securities; provided, however,
                 that the uncertificated Securities are issued in registered
<PAGE>   40
PAGE 39

                 form for purposes of Section 163(f) of the Internal Revenue
                 Code of 1986, as amended, or in a manner such that the
                 uncertificated Securities are described in Section
                 163(f)(2)(B) of the Internal Revenue Code of 1986, as amended;

                    (4) to add guarantees with respect to the Securities;

                    (5) to add to the covenants of the Company for the benefit
                 of the Holders or to surrender any right or power herein
                 conferred upon the Company;

                    (6) to comply with any requirements of the SEC in
                 connection with qualifying this Indenture under the TIA; or

                    (7) to make any change that does not adversely affect the
                 rights of any Securityholder in any material respect.

                    After an amendment under this Section becomes effective,
the Company shall mail to Securityholders a notice briefly describing such
amendment.  The failure to give such notice to all Securityholders, or any
defect therein, shall not impair or affect the validity of an amendment under
this Section.

                    SECTION 8.02.  With Consent of Holders.  The Company and
the Trustee may amend this Indenture or the Securities without notice to any
Securityholder but with the written consent of the Holders of at least a
majority in principal amount of the Securities.  However, without the consent
of each Securityholder affected, an amendment may not:

                    (1) reduce the amount of Securities whose Holders must
                 consent to an amendment;

                    (2) reduce the rate of or extend the time for payment of
                 interest on any Security;

                    (3) reduce the principal of or extend the fixed maturity of
                 any Security;

                    (4) reduce the premium payable upon the redemption of any
                 Security or change the time at which any Security may or shall
                 be redeemed;

                    (5) make any Security payable in money other than that 
                 stated in the Security; or

                    (6) make any change in Section 5.04 or this Section;

and, provided further, that in case more than one series of Securities (or
Securities of a single series which have different Terms) shall be outstanding
under this Indenture, and any such proposed amendment shall affect the rights
of Holders of the Securities of one or more series (or Securities of a single
series which have different Terms) and shall not affect the rights of Holders 
of the Securities of one or more of the other series (or Securities of a 
single series which have

<PAGE>   41
PAGE 40

different Terms), then only Holders of Securities to be affected shall have
authority or be required to consent to or approve such amendment.  Any waiver
of a default provided for in Section 5.04 shall be deemed to affect the
Securities of all series, and, subject to the foregoing, any modification of
the provisions of any sinking fund or covenant established in respect of
Securities of a particular series (or Securities of a single series having the
same Terms) shall be deemed to affect only such Securities.

                    It shall not be necessary for the consent of the Holders
under this Section 8.02 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent approves the substance
thereof.

                    After an amendment under this Section becomes effective,
the Company shall mail to Holders of the affected Securities a notice briefly
describing such amendment.  The failure to give such notice to all
Securityholders (or all Holders of the affected Securities), or any defect
therein, shall not impair or affect the validity of an amendment under this
Section.

                    SECTION 8.03.  Compliance with Trust Indenture Act.  Every
amendment to this Indenture or the Securities shall comply with the TIA as then
in effect.

                    SECTION 8.04.  Revocation and Effect of Consents and
Waivers.  A consent to an amendment or any other action hereunder or a waiver
by a Holder of a Security shall bind the Holder and every subsequent Holder of
that Security or portion of the Security that evidences the same debt as the
consenting Holder's Security, even if notation of the consent or waiver is not
made on the Security.  However, any such Holder or subsequent Holder may revoke
the consent or waiver as to such Holder's Security or portion of the Security
if the Trustee receives the notice of revocation before the date the amendment
or waiver becomes effective.  After an amendment or waiver becomes effective,
it shall bind every Securityholder.

                    The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Securityholders entitled to take
any action under this Indenture by vote or consent.  Such record date shall be
the later of 30 days prior to the first solicitation of such consent or vote or
the date of the most recent list of Holders of the affected Securities
furnished to the Trustee pursuant to Section 2.07 prior to such solicitation.
If a record date is fixed, those persons who were Securityholders at such
record date (or their duly designated proxies), and only those persons, shall
be entitled to take such action by vote or consent or to revoke any vote or
consent previously given, whether or not such persons continue to be
Securityholders after such record date.

                    SECTION 8.05.  Notation on or Exchange of Securities.  If
an amendment changes the terms of a Security, the Trustee may require the
Holder of the Security to deliver it to the Trustee.  The Trustee may place an
appropriate notation on the Security regarding the changed terms and return it
to the Holder.  Alternatively, if the Company or the Trustee so determines, the
Company in exchange for the Security shall issue and the Trustee shall
authenticate a new
<PAGE>   42
PAGE 41

Security that reflects the changed terms.  Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

                    SECTION 8.06.  Trustee To Sign Amendments.  The Trustee
shall sign any amendment authorized pursuant to this Article 8 if the amendment
does not adversely affect the rights, duties, liabilities or immunities of the
Trustee.  If it does, the Trustee may but need not sign it.  In signing such
amendment the Trustee shall be entitled to receive indemnity reasonably
satisfactory to it and to receive, and (subject to Section 6.01) shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
stating that such amendment is authorized or permitted by this Indenture.


                                   ARTICLE 9

                                   Redemption

                    SECTION 9.01.  Applicability.  Securities of any series
which are redeemable before their final maturity shall be redeemable in
accordance with their Terms and (except as otherwise specified as contemplated
by Section 2.01 for Securities of any series) in accordance with this Article.

                    SECTION 9.02.  Notice to Trustee.  The Company may, with
respect to any series of Securities (or Securities of a series having the same
Terms), reserve the right to redeem and pay such Securities or any part
thereof, or may covenant to redeem and pay the series of Securities (or
Securities of a series having the same Terms) or any part thereof, before
maturity at such time and on such terms as provided for in such Securities.  If
a series of Securities (or Securities of a series having the same Terms) is
redeemable and the Company wants or is obligated to redeem all or part of the
series of Securities (or Securities of a series having the same Terms) pursuant
to the Terms of such Securities, the Company shall notify the Trustee of the
redemption date and the Principal Amount of the series of Securities (or
Securities of a series having the same Terms) to be redeemed.  The Company
shall give such notice at least 60 days before the redemption date (or such
shorter notice as may be acceptable to the Trustee in its sole discretion).

                    SECTION 9.03.  Selection of Securities To Be Redeemed.  If
less than all the Securities of a series (or Securities of a series having the
same Terms) are to be redeemed, the Trustee, not more than 60 days prior to the
redemption date, shall select the Securities of the series (or Securities of a
series having the same Terms) to be redeemed pro rata or by lot or by such
other method as the Trustee shall deem fair and appropriate.  The Trustee shall
make the selection from Securities that are outstanding and that have not
previously been called for redemption.  Securities of the series (or Securities
of a series having the same Terms) and portions of them selected by the Trustee
shall be in amounts of $1,000 or integral multiples of $1,000 or with respect
to Securities of any Series issuable in other denominations pursuant to Section
2.01(8), in amounts equal to the minimum principal denomination for each such
series
<PAGE>   43
PAGE 42

and in integral multiples thereof.  Provisions of this Indenture that apply to
Securities of that series (or Securities of a series having the same Terms)
called for redemption also apply to portions of Securities of that series (or
Securities of a series having the same Terms) called for redemption. The
Trustee shall promptly notify the Company in writing of the Securities selected
for redemption and, in the case of any Securities selected for partial
redemption, the Principal Amount thereof to be redeemed.

                    SECTION 9.04.  Notice of Redemption.  (a)  At least 30 days
but not more than 60 days before a redemption date, unless a shorter period is
specified in the Terms of the Securities to be redeemed, the Company shall
cause to be mailed a notice of redemption by first-class mail to each Holder 
of Securities that are to be redeemed.

                    (b)  All notices of redemption shall identify the
Securities to be redeemed and shall state:

                    (1) the redemption date;

                    (2) the redemption price and interest, if any, payable upon
                 such redemption;

                    (3) if less than all the outstanding Securities of a series
                 (or Securities of a series having the same Terms) are to be
                 redeemed, the identification (and, in the case of partial
                 redemption, the Principal Amounts) of the particular
                 Securities to be redeemed;

                    (4) the name and address of the Paying Agent;

                    (5) that the Securities called for redemption must be
                 surrendered to the Paying Agent to collect the redemption
                 price; and

                    (6) that interest on Securities called for redemption
                 ceases to accrue on and after the redemption date.

                    (c) If at the time of any notice of redemption the Company
shall not have deposited or caused to be deposited with the Trustee moneys
sufficient to redeem all the Debentures called for redemption, such notice
shall state that it is subject to the deposit of the redemption moneys with the
Trustee not later than the opening of business on the redemption date and shall
be of no effect unless such moneys are so deposited. If such moneys are not
deposited by such date and time, the Trustee shall promptly notify the holders
of all Debentures called for redemption of such fact.

                    At the Company's request, the Trustee shall give the notice
of redemption in the Company's name and at the Company's expense.

                    SECTION 9.05.  Effect of Notice of Redemption.  Once notice
of redemption is mailed, Securities called for redemption become due and
payable on the redemption date at the redemption price.  Any failure to mail
notice of redemption or any defect therein shall not affect the redemption of
any other Securities called for redemption.  Upon surrender to the Paying Agent
of such Securities, such Securities shall be paid at the redemption price plus
accrued interest to the redemption date, but installments of interest due on or
prior to the redemption date will be payable to the Holders of such Securities
of record at the close of business on the relevant record dates, unless
otherwise specified in the Terms of such Securities.
<PAGE>   44
PAGE 43

                    SECTION 9.06.  Deposit of Redemption Price.  On or before
the redemption date, the Company shall deposit with the Paying Agent money
sufficient to pay the redemption price of and interest accrued to the
redemption date on all Securities to be redeemed on that date.

                    SECTION 9.07.  Securities Redeemed in Part.  Upon surrender
of a Security that is redeemed in part, the Company shall issue and the Trustee
shall authenticate for the Holder of that Security a new Security or Securities
of the same series and terms in authorized denominations equal in aggregate
principal amount to the unredeemed portion of the Security surrendered.


                                   ARTICLE 10

                                 Sinking Funds

                    SECTION 10.01.  Applicability.  The provisions of this
Article shall be applicable to any sinking fund for the retirement of
Securities, except as otherwise specified as contemplated by Section 2.01 for
Securities of any series.

                    The minimum amount of any sinking fund payment provided for
by the Terms of any Securities is herein referred to as a "Mandatory Sinking
Fund Payment", and any payment in excess of such minimum amount provided for by
the terms of such Securities is herein referred to as an "Optional Sinking Fund
Payment".  If provided for by the Terms of Securities, the cash amount of any
sinking fund payment may be subject to reduction as provided in Section 10.02.
Each sinking fund payment shall be applied to the redemption of Securities of
any series (or Securities of a series having the same Terms) as provided for by
the Terms of such Securities.

                    SECTION 10.02.  Satisfaction of Sinking Fund Payments with
Securities.  The Company may, in satisfaction of all or any part of any sinking
fund payment with respect to the Securities to be made pursuant to the Terms of
such Securities as provided for by such Terms, (1) deliver outstanding
Securities of such series having the same Terms (other than any of such
Securities previously called for redemption) and (2) apply as credit Securities
of such series having the same Terms which have been redeemed either at the
election of the Company pursuant to the Terms of such Securities or through the
application of permitted Optional Sinking Fund Payments pursuant to the Terms
of such Securities, provided that such Securities have not been previously so
credited.  Such Securities shall be received and credited for such purpose by
the Trustee at the price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.  If as a result of the delivery or credit of Securities
in lieu of cash payments pursuant to this Section 10.02, the Principal Amount
of Securities to be redeemed in order to exhaust the aforesaid cash payment
shall be less than $100,000, the Trustee need not call Securities for
redemption, except upon receipt of a Company Order that such action be taken,
and such cash payment shall be held by the Trustee or a Paying Agent and
applied to the next succeeding sinking fund payment with
<PAGE>   45
PAGE 44

respect to such series of Securities (or Securities of such series having the
same Terms), provided, however, that the Trustee or such Paying Agent shall at
the request of the Company from time to time pay over and deliver to the
Company any cash payment so being held by the Trustee or such Paying Agent upon
delivery by the Company to the Trustee of Securities of that series having the
same Terms purchased by the Company having an unpaid Principal Amount equal to
the cash payment required to be released to the Company.

                    SECTION 10.03.  Redemption of Securities for Sinking Fund.
Not less than 60 days prior to each sinking fund payment date for any series of
Securities (or Securities of such series having the same Terms), the Company
will deliver to the Trustee an Officers' Certificate specifying the amount of
the next ensuing Mandatory Sinking Fund Payment for that series (or Securities
of such series having the same Terms) pursuant to the Terms of that series, the
portion thereof, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting
of Securities of that series (or Securities of such series having the same
Terms) pursuant to Section 10.02, and the optional amount, if any, to be added
in cash to the next ensuing Mandatory Sinking Fund Payment, and the Company
shall thereupon be obligated to pay the amount therein specified.  Not less
than 30 days before each such sinking fund payment date the Trustee shall
select the Securities to be redeemed upon such sinking fund payment date in the
manner specified in Section 9.03 and cause notice of the redemption thereof to
be given in the name of and at the expense of the Company in the manner
provided in Section 9.04.  Such notice having been duly given, the redemption
of such Securities shall be made upon the terms and in the manner stated in
Sections 9.05, 9.06 and 9.07.

SECURITIES AND EXCHANGE COMMISSION

(Release No. 35-26361; 70-8627)

The Columbia Gas System, Inc.
Memorandum Opinion and Order Approving Plan of Reorganization of Registered
Holding Company Under Section 11(f) and Registered Holding Company's
Participation in Subsidiary's Plan of Reorganization and Related Transactions;
Issuing Report Under Section 11(g); and Reserving Jurisdiction

August 25, 1995

THIS ORDER AND REPORT IS REQUIRED BY THE PUBLIC UTILITY HOLDING COMPANY ACT OF
1935. SECURITY HOLDERS SHOULD READ THE DISCLOSURE STATEMENTS  PROVIDED TO THEM
BY THE DEBTORS-IN-POSSESSION BEFORE DETERMINING WHETHER OR NOT TO ACCEPT THE
PLANS.

     The Columbia Gas System, Inc. ("Columbia"), a registered holding company,

Wilmington, Delaware, has filed an application-declaration, as amended, with

the Commission under sections 6, 7, 9, 10, 11(f), 11(g), 12(b), 12(c) and 12(e)

of the Public Utility Holding Company Act of 1935, as amended ("Act"), and

rules 42, 43, 45, 49, 54, 62, 64 and 65 thereunder, seeking approval of its

Plan of Reorganization, as amended ("Columbia Plan"), first filed with the U.S.

Bankruptcy Court for the District of Delaware ("Bankruptcy Court") on April 17,

1995 and its participation in a plan of reorganization ("TCO Plan") filed with

the Bankruptcy Court on the same date by its wholly owned nonutility

subsidiary, Columbia Gas Transmission Corporation ("Columbia Transmission").(1)

The Commission issued a notice of the filing on June 23, 1995 (Holding Co. Act

Release No. 26318).  No request for a hearing was received.




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

     (1) The plans and the respective disclosure statements were
filed pursuant to the provisions of Chapter 11 of the United
States Bankruptcy Code ( Bankruptcy Code"), 11 U.S.C. Section 101 et
seq.

     Rule 49(c) exempts the TCO Plan from the requirement of
Commission approval.
<PAGE>   2
I.   BACKGROUND

     Columbia is engaged, through subsidiary companies, in the exploration,

production,purchase, marketing, storage, transmission and distribution of

natural gas, and in other energy operations, such as electric power generation

and propane distribution.(2) Columbia Transmission owns and operates an

approximately 19,000 mile natural gas transmission pipeline network and related

extensive underground gas storage fields that serve parts of thirteen states in

the Northeastern, Mid-Atlantic, Midwestern and Southeastern regions of the

United States and the District of Columbia.(3)  Columbia Transmission is

currently engaged almost entirely in the business of transporting and storing

gas for various affiliated and nonaffiliated gas distribution companies, gas

marketers, producers and end users of gas ("Customers").(4)


     Columbia, as a holding company, has provided debt and equity financing for

all its operating subsidiaries, including Columbia Transmission, and has served

as the principal vehicle for raising funds in the capital markets for the

Columbia system companies.  Columbia has generally reinvested in its operating

subsidiaries the proceeds of its equity and debt issues, as well as cash flows

from its subsidiaries.




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

     (2) Columbia has five wholly owned public-utility subsidiary
companies: Columbia Gas of Ohio, Inc., Columbia Gas of Kentucky,
Inc., Columbia Gas of Maryland, Inc., Columbia Gas of
Pennsylvania, Inc. and Commonwealth Gas Service, Inc.

     (3) Columbia Transmission is one of two interstate pipeline
companies owned by Columbia.

     (4) The rates, charges, services and facilities of Columbia
Transmission are subject to relation by the Federal Energy
Regulatory Commission ("FERC"), primarily pursuant to the Natural
Gas Act, 15 U.S.C. Section Section I7 et seq.
<PAGE>   3
     Prior to June 1985, Columbia made loans to Columbia Transmission on an

unsecured basis and, at the Petition Date, held unsecured obligations of

Columbia Transmission aggregating $351 million, including prepetition accrued

interest.  Loans made to Columbia Transmission after June 1985 were secured by

first mortgage liens on substantially all of Columbia Transmission's assets.

As of July 31, 1991 ("Petition Date"), Columbia held secured obligations of

Columbia Transmission aggregating approximately $1.34 billion in principal.

Prepetition and postpetition interest accrued through December 31, 1995 (the

assumed "Effective Date" of the Columbia and TCO Plans and the date to which

all financial projections have been made in this filing)(5) on such secured

obligations are projected to be approximately $644 million.


     Both Columbia and Columbia Transmission have been debtors-in-possession

pursuant to Sections 1107 and 1108 of the Bankruptcy Code since the Petition

Date.(6) The Chapter 11 filings were precipitated by a combination of events

that adversely affected Columbia Transmission's physical operations and

financial viability and, in turn, caused a liquidity shortfall for Columbia and

the Columbia system.(7)




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

     (5) The Plans allow for the Effective Date to occur as late as
June 28, 1996.

     (6) The Commission filed a Notice of Appearance under Section
1109 of the Bankruptcy Code in each proceeding. Except for the
appointment of a fee examiner to review the reasonableness of
fees and expenses incurred by certain professionals involved in
the case, no trustee or examiner has been appointed by the
Bankruptcy Court.

     (7) As chief among these events, Columbia identifies federal
legislative and regulatory actions affecting Columbia
Transmission's ability to sell the gas it had contracted to buy
and to recover its costs from its Customers, and Columbia
Transmission's continuing contractual obligations to purchase gas
at prices above those at which it was able to market gas. These
problems were exacerbated by record-setting warm weather that led
to an unexpected and persistent oversupply of gas.
<PAGE>   4
     As a result of Columbia Transmission's bankruptcy filing and its rejection

of more than 4,800 above-market gas purchase contracts with producers

("Producers"), Columbia Transmission recorded liabilities of approximately $1

billion for estimated contract rejection costs.  In addition, approximately

$200 million of take-or-pay and other miscellaneous Producer claims were

recorded.  The Producer counterparties to those contracts filed claims for

rejection damages and other prepetition contractual amounts in excess of $13

billion.


II.  COLUMBIA'S SUPPORT OF THE TCO PLAN

     The TCO Plan incorporates terms of an agreement reached by Columbia

Transmission with its major Producer creditors ("Producer Agreement") and

approved by the Bankruptcy Court on June 16, 1995.(8)  The Producer Agreement

also provides for Columbia Transmission's agreement, backed by Columbia, as to

the minimum distribution to be paid to Producers and other creditors under the

TCO Plan.  Distributions to these producers ("Initial Accepting Producers")

represent more than 80 of the approximately $1.2 billion that would be

distributed to Producer creditors under the TCO Plan to resolve all Producer

claims.  The TCO Plan offers to all the remaining Producers proposals for

settlement of the allowable amounts of their claims.  Remaining Producers that

ultimately reject the settlement offers ("Dissenting Producers") will be free

to litigate the amount of their claims before the Bankruptcy Court and will

receive the same percentage payout ultimately allowed by the Bankruptcy Court

on their claims as that received by the Initial Accepting Producers and

subsequent settling Producers (together, "Accepting




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

     (8) The Producer Agreement reflects settlements of the
allowable amount of the claims filed against Columbia
Transmission by 17 major Southwest gas producers and a large
group of Appalachian producers.
<PAGE>   5
Producers").  As of June 30, 1995, Accepting Producers represented

approximately 92% of the aggregate amount of allowed claims proposed in the TCO

Plan.(9)


     The TCO Plan also incorporates the terms of a settlement among Columbia

Transmission and virtually all of its Customers ("Customer Settlement") on

numerous FERC Order No. 636 transition cost, rate and other bankruptcy matters.

Remaining Customers can either accept a settlement on terms similar to those of

the Customer Settlement, or dissent and litigate the amount and priority of

their claims.(10)


     To facilitate the TCO Plan, and in exchange for settlement of the claims

asserted in a complaint filed with the Bankruptcy Court on March 18, 1992 by

the Official Committee of Unsecured Creditors of Columbia Transmission

("Intercompany Complaint")(11) and




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

     (9) It is a waivable condition to the TCO Plan that the
settlement values of Accepting Producers as of the Effective Date
equal 90% of the total settlement values proposed therein.


     (10) Columbia states that Columbia Transmission's Customer
Settlement has the support of all of its major customers.  While
the settlement permits non-supporting parties to litigate their
claims, Columbia Transmission's financial exposure from such
litigation is considered de minimis.


     (11) The complaint, filed against Columbia and Columbia Natural
Resources, Inc. ("CNR"), its oil and gas exploration and
development subsidiary, alleged that the $1.7 billion of Columbia
Transmission's secured and unsecured debt securities held by
Columbia should be recharacterized as capital contributions
(rather than loans) and equitably subordinated to the claims of
Columbia Transmission's other creditors. The complaint also
challenged interest and dividend payments of approximately $500
million by Columbia Transmission to Columbia during the period
from 1988 to the Petition Date.  Finally, the complaint alleged
that a 1990 transfer of gas properties from Columbia Transmission
to CNR was a fraudulent transfer.

     At the Bankruptcy Court's request, the trial proceedings for
the Intercompany Complaint were transferred to and tried by the 
U.S. District Court for the District of Delaware.  The District 

<PAGE>   6
Columbia's retention of the ownership of Columbia Transmission, the Columbia

Board of Directors authorized a settlement ("Columbia Omnibus Settlement"),

whereby Columbia will:

            (1) make a capital infusion of approximately $1 billion into

     Columbia Transmission. The capital infusion will have two components.

     First, Columbia will agree to a restructuring of Columbia Transmission's

     secured debt.  As part of a recapitalization of Columbia Transmission,

     Columbia will accept an aggregate amount of up to $1.5 billion short-term

     and long-term first mortgage bonds ("TCO Mortgage Bonds"), described

     below, in settlement of the approximately $2 billion claim held by

     Columbia under existing Columbia Transmission first mortgage bonds.(12)  

     The restructuring will result in an approximately $500 million capital

     contribution to Columbia Transmission of the balance of the claim.




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

Court was expected to render a decision in June 1995, but has 
agreed at the parties' request to defer issuing its ruling 
pending the parties' pursuit of consensual reorganization plans. 
In connection with the approval of the TCO Plan, the District 
Court's approval of the Columbia Omnibus Settlement will be sought.

     (12) The short-term TCO Mortgage Bonds must be repaid no later
than April 30 of the year following their issuance and will bear
interest on a monthly basis equivalent to the composite weighted
average effective cost incurred by Columbia on its short-term
borrowings. The bonds may be prepaid or redeemed at any time
without prepayment penalty.

     The long-term TCO Mortgage Bonds will be dated the date of
their issue and be repaid in equal annual installments over a
period not to exceed 30 years or at maturity. The bonds may be
issued in multiple series with terms similar to the New Indenture
Securities (as described below) issued by Columbia under the
Columbia Plan. Interest on the bonds will accrue from the date of
issuance and will be paid semi-annually on the unpaid principal
thereof.  The interest rate will be the actual cost of money to
Columbia with respect to the issuance by Columbia of its long-
term debt securities.  A default rate equal to 2% per annum in
excess of the stated rate on the unpaid principal or interest
amounts of the bonds would be assessed if any interest or
principal becomes past due.  If Columbia Transmission is not a
subsidiary of Columbia at the time of prepayment, the bonds may
be prepaid with a prepayment penalty equal to the interest rate
on the bonds, declining ratably on each anniversary date over the
life of the issue.
<PAGE>   7
            The TCO Mortgage Bonds will be issued under the Indenture and Deed

     of Trust between Columbia Transmission and Wilmington Trust Company, dated

     August 30, 1985, as amended ("Wilmington Trust Indenture"), previously

     authorized by order of the Commission.(13) The TCO Mortgage Bonds will be

     secured by a perfected first security interest in all of Columbia

     Transmission's property with certain exceptions pursuant to the Wilmington

     Trust Indenture.


            Second, Columbia will agree to provide cash to Columbia

     Transmission necessary to ensure that the total amount distributable under

     the TCO Plan equals approximately $3.9 billion as of December 31, 1995. It

     is anticipated that Columbia would provide an additional capital

     contribution to Columbia Transmission of approximately $500 million.(14)


            (2) guarantee the settlement reached by Columbia Transmission with

     its Customers and payments to dissenting Customers with respect to the

     Customer Settlement ("TCO Guarantee"), and guarantee the payment of the

     distribution percentage of ultimately allowed claims of other unsecured

     creditors, including Dissenting Producers.


     In the event that payments required by the TCO Plan to Dissenting

Producers (and dissenting Customers) increase the total required distributions

over the projected $3.9 billion by




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

     (13) Columbia Gas Transmission Corp., Holding Co. Act Release
No. 23813 (Aug. 30, 1985).


     (14) Approximately $300 million of this amount could be met by
Columbia's proportionate recovery on the Columbia Transmission
unsecured debt held by it, together with a dividend out of
retained earnings by CNR to Columbia following CNR's recovery on
its claims.
<PAGE>   8
an amount that requires external funding, Columbia will have the option to

deliver its common stock in lieu of cash payments, as well as the option to

sell its common stock in the marketplace and use the proceeds for such excess

distributions. Under these circumstances, whichever technique is employed,

Columbia's investment in Columbia Transmission will be correspondingly

increased.


     Initial Accepting Producers have agreed that 5% of the distributions due

to them will be held back, and, to the extent that claim values in excess of

the settlement values contained in the TCO Plan are agreed to or allowed, the

amount held back will be applied, with dollar-for-dollar matching by Columbia

Transmission and Columbia under the TCO Guarantee, to pay the ultimate

distributions to Dissenting Producers.  Thus, there is a sharing by Accepting

Producers of a portion of the risk that the aggregate distribution to Producers

pursuant to the TCO Plan may exceed $1.2 billion, the settlement amount

contained in the Plan. If the holdback were to be exhausted, Columbia

Transmission would be required to pay the entire amount of any excess

distributions.  Columbia states that although there is insufficient information

at present for Columbia Transmission to evaluate fully all claims, and the

outcome of litigation is subject to uncertainty, Columbia Transmission

currently estimates that its ultimate payment to Producers, after any

litigation and after giving effect to the Producer holdback, may exceed the

$1.2 billion distribution projected in the TCO Plan (which is based on 100%

Producer acceptance) but should not exceed $1.3 billion.


     To the extent that additional funds are necessary to fund allowed claims

of Dissenting Producers, Columbia or Columbia Transmission may distribute cash,

or Columbia may issue its
<PAGE>   9
common stock to the Dissenting Producers on behalf of Columbia Transmission in

exchange for consideration from Columbia Transmission equal to the then current

market value of the Common Stock.  Columbia may also issue its common stock or

other securities on the open market and distribute the proceeds to Columbia

Transmission as a capital contribution. To the extent that the TCO Plan

reserves the right to Columbia to issue securities other than its common stock,

Columbia requests the Commission to reserve jurisdiction over the terms of such

securities issues.


     The aggregate capital contribution to Columbia Transmission by Columbia of

approximately $1 billion will result in an approximately 70%-30% debt-equity

structure for Columbia Transmission.  Columbia Transmission's debt-to-equity

ratio is projected to become approximately 60%/40% by 1997 upon the repayment

of borrowings used to finance certain contingent assets created as a result of

emergence from bankruptcy.


     Columbia states that in the aggregate, the consideration that it will pay

for the settlement of the claims asserted in the Intercompany Complaint and the

retention of ownership of Columbia Transmission cannot be expressed as a

precise dollar amount, but reflects substantial additional consideration from

Columbia to the Columbia Transmission estate to facilitate the reorganization

of Columbia and Columbia Transmission.  Columbia further states that the

Columbia Omnibus Settlement will provide substantial benefits to Columbia, in

addition to the retention of ownership of Columbia Transmission, by resolving

numerous disputes with Customers and Producers affecting the economic value of

the Columbia Transmission estate on terms Columbia believes to be fair and

reasonable.  Finally, settlement will permit both Columbia and Columbia
<PAGE>   10
Transmission to emerge from bankruptcy as promptly as possible, to pay their

creditors, and to pursue ongoing business objectives free of the burdens and

III.  THE COLUMBIA PLAN

     A.     Introduction

     Under the Columbia Plan, Columbia proposes to issue up to an aggregate

of $3.65 billion in new securities, consisting of up to $3.25 billion in debt

and up to $400 million in equity.(15)  The Columbia Plan is intended to provide

for payment of substantially all liquidated allowed claims of Columbia's

creditors on the Effective Date.  Holders of claims for borrowed money

generally will receive a combination of (i) cash, to the extent available (as

determined by Columbia), (ii) new debentures of Columbia, to be issued under a

new form of indenture, and (iii) equity securities of Columbia, consisting of

preferred stock and dividend enhanced convertible stock.  Holders of Columbia

common stock will retain their equity interests under the Columbia Plan.  The

debt and equity securities proposed to be issued are discussed hereinafter. 

Under certain circumstances provided in the Columbia Plan, Columbia may redeem

the equity securities for cash.(16)




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

     (15) Columbia may issue additional common stock to satisfy
certain of its obligations under the Columbia Omnibus Settlement,
as discussed in Part II above, and to fund the settlement of
securities litigation, described below.

     (16) The amount of cash consideration to be distributed to
holders of borrowed money claims pursuant to the Columbia Plan
will be determined by Columbia shortly before the Effective Date,
and will be dependent upon the cash available at that time.  The
financial projections contained in the Columbia disclosure
statement project the distribution of $900 million of available
cash as of the Effective Date (the majority of which is assumed
to be borrowed under the Term Facility described below) in
respect of such claims. The balance of the distribution in
respect of such claims will be in the form of New Indenture
Securities, DECS and Preferred Stock, as defined below. If the
Term Facility is available for borrowing at a cost less than the
cost of issuing new debentures, Columbia has agreed to borrow
$350 million for 
<PAGE>   11

     In addition to the proposed issuances of debt and equity securities by

Columbia, the Columbia Plan also contemplates certain amendments to Columbia's

Certificate of Incorporation and the assumption by Columbia and Columbia

Transmission of the Tax Allocation Agreement that provides for the allocation

of tax benefits and liabilities among Columbia system companies.


     B.     Debt Securities

     As noted previously, Columbia proposes to issue up to $3.25 billion in

debt securities under the Columbia Plan.


            1.    Debentures

                  Columbia seeks to issue up to $2.1 billion in debentures

            ("New Indenture Securities") under a new indenture ("New

            Indenture").(17) The New Indenture Securities will be general,

            unsecured senior obligations of Columbia, issued in seven series

            with maturities of approximately five, seven, ten, twelve, fifteen,

            twenty and thirty years, respectively.  Each New Indenture Security

            will bear interest, payable semi-annually, from the Effective Date

            (or from the most recent interest payment date to which interest

            has been paid). The annual interest rate for each series of New

            Indenture Securities will be based on market rates for comparable

            securities at the time of issue. It is expected that the interest

            rate on any series will not exceed 10





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

distribution to creditors in lieu of New
Indenture Securities, DECS and Preferred Stock.

     (17) The New Indenture is similar to that authorized by the
Commission in Consolidated Natural Gas Holding Co. Act Release
No. 26245 (Mar. 6, 1995). Columbia states that an application on
Form T-3 for qualification of the New Indenture under the Trust
Indenture Act of 1939, as amended, will be filed and become
effective by the Effective Date.
<PAGE>   12

            percent per annum. The principal amount of each series of New

            Indenture Securities will be payable on their respective maturity

            dates. Certain series of New Indenture Securities may be redeemable

            at a premium at the option of Columbia.


            2.    Bank Borrowings

            For the purpose of Financing shorter-term requirements under the

     TCO Plan and Columbia Plan, Columbia expects to arrange two types of bank

     credit facilities ("Bank Facilities") on or before the Effective Date, to

     permit aggregate borrowings of up to $1.15 billion. If cash available

     through the Bank Facilities or from operations is reduced from currently

     projected levels, the principal amount of New Indenture Securities to be

     issued pursuant to the Columbia Plan would be increased proportionately.

     Under no circumstances would the aggregate of New Indenture Securities and

     Bank Facilities under the Columbia Plan exceed $3.25 billion.


                  a.   Term Facility

                  The first type would be a senior, unsecured term credit

            facility in an aggregate principal amount of up to $450 million

            ("Term Facility"). Amounts available to be borrowed under the Term

            Facility would be applied to payments in respect of claims of

            Columbia creditors, to fund obligations of Columbia under the

            Columbia Omnibus Settlement and for general corporate purposes.

            Amounts borrowed under the Term Facility would rank pari passu with

            all other senior, unsecured obligations of Columbia, including the

            New Indenture Securities.
<PAGE>   13
                       It is anticipated that the initial term of the Term

            Facility will be two years.  Interest rates on borrowings

            under the facility, depending on the nature of the borrowing,

            will be the prime rate or the applicable LIBOR rate plus no

            more than .75% or the applicable certificate of deposit rate

            plus no more than .875%.


                  b.   Revolving Facility

                  Columbia also expects to arrange one or more senior,

            unsecured revolving Bank Facilities in an aggregate principal

            amount of up to $700 million ("Revolving Facility") to provide (i)

            working capital for Columbia and its subsidiaries and (ii) up to

            $100 million face amount of letters of credit to be issued for the

            account of Columbia and its subsidiaries in the ordinary course of

            business. Amounts borrowed under the Revolving Facility and

            reimbursement for drawings under letters of credit issued

            thereunder would rank pari passu with all other senior, unsecured

            obligations of Columbia, including the New Indenture Securities. At

            the option of Columbia, the Term Facility and Revolving Facility

            may be combined in a single facility or may be multiple facilities.


                  The initial term of the Revolving Facility is expected not to

            exceed five years. Up to $100 million of the facility is expected

            to be used solely for letters of credit to be issued for the

            account of Columbia (a portion of which may be denominated in

            Canadian dollars) in the ordinary course of' its business. Interest

            rates on borrowings under the Revolving Facility, depending on the

            nature of the borrowing, will be the prime rate or specified

            margins over the applicable LIBOR rate or applicable certificate of

            deposit rate on the same or similar margin and maturity terms as

            the
<PAGE>   14
            Term Facility. The specific terms of the Revolving Facility,

            including, without limitation, interest rates, repayment terms,

            conditions to borrowings, representations and warranties, covenants

            and events of default will be negotiated by Columbia and

            prospective providers of the Revolving Facility.


            B.    Equity Securities

            The Columbia Plan contemplates the issuance by Columbia of up to

     $400 million of equity through the issuance of up to $200 million each of

     preferred stock ("Preferred Stock") and of Dividend Enhanced Convertible

     Stock ("DECS"). Columbia proposes the possible issuance of its common

     stock (in addition to any LESOP Shares, as defined below) on behalf of

     Columbia Transmission in connection with the TCO Guarantee and, as

     described below, to fund the Securities Litigation Settlement.


                  1.   Preferred Stock

                  The Preferred Stock will have a liquidation value of $25 per

            share and, as to dividend and liquidation rights, will rank equally

            with the DECS but prior to the common stock. Holders of Preferred

            Stock will be entitled to receive, when, as and if declared by

            Columbia's board of directors, cumulative preferential cash

            dividends accruing from the Effective Date at a rate per share that

            is to be determined at the time of issuance in accordance with a

            pricing formula. It is currently expected that the dividend rate

            for Preferred Stock will not exceed 11 percent per annum.
<PAGE>   15
                  Columbia may, at its option, redeem the Preferred Stock, in

            whole or in part, on or prior to the 120th day after the Effective

            Date, if, after giving effect to the redemption, either (i) the

            aggregate liquidation value of the Preferred Stock outstanding

            would be $50 million or more, unless after giving effect thereto,

            no Preferred Stock would be outstanding, or (ii) no DECS would be

            outstanding. If the Preferred Stock is not so redeemed, the annual

            dividend rate per share will be reset and increased by 100 basis

            points, effective as of the 120th day after the Effective Date.

            Columbia may also redeem the Preferred Stock in whole or in part on

            or after the fifth anniversary of the Effective Date. Upon any such

            redemption by Columbia, a holder of Preferred Stock will receive,

            in exchange for each share so redeemed, cash in an amount equal to

            the sum of the liquidation value thereof and all accrued and unpaid

            dividends thereon to the date fixed for redemption.


                  The holders of Preferred Stock shall not have voting rights

            except as required by law and as follows: (i) if dividends on the

            Preferred Stock are in arrears and unpaid for six quarterly

            dividend periods, the holders of the Preferred Stock will be

            entitled to vote, on the basis of one vote for each share, for the

            election of two directors of Columbia, such directors to be in

            addition to the number of directors constituting the board of

            directors immediately prior to the accrual of such right; and (ii)

            the holders of Preferred Stock will have voting rights with respect

            to certain modifications of Columbia's certificate of

            incorporation.
<PAGE>   16
            2.    DECS

            The proposed DECS will be shares of convertible preferred stock of

     Columbia and will have dividend, liquidation and voting rights similar to

     those of the Preferred Stock described above. The annual dividend rate

     will be that required to make the market value of the DECS comparable to

     the market value of the common stock and the liquidation value will be

     based on the market value of the common stock, each as of a specified

     date. It is currently expected that the dividend rate on the DECS will not

     exceed 11 percent per annum.


            Columbia will have the right to redeem the DECS, in whole or in

     part, on or prior to the 120th day after the Effective Date if, after

     giving effect to the redemption, either no DECS are outstanding or the

     aggregate liquidation value of outstanding DECS is at least $50 million.

     Upon such redemption, each holder will receive for each redeemed share

     cash in an amount equal to the liquidation value plus accrued and unpaid

     dividends. If Columbia fails to redeem the DECS in whole, the annual

     dividend rate per unredeemed share will increase by 100 basis points

     effective as of the 120th day after the Effective Date.


            Columbia will also have the right to redeem the DECS, in whole or

     in part, on or after either the fourth anniversary of the Effective Date

     or one month prior to the fifth anniversary of the Effective Date (as

     determined by Columbia), and prior to the fifth anniversary of the

     Effective Date. Upon such redemption, each holder will receive for each

     share a number of shares of Columbia common stock equal to the lesser of

     (a) the redemption price of the DECS on the date of redemption (which

     reflects liquidation price plus accrued dividends
<PAGE>   17
     and, in some cases, a premium) divided by the current market price of

     common stock as of the trading day prior to the public announcement of the

     call for redemption, and (b) the number of shares that would be received

     upon conversion into common stock (described below), as adjusted to

     reflect any accrued dividends and premium payable upon redemption.


            After the 120th day following the Effective Date and before the

     fifth anniversary of the Effective Date ("Mandatory Conversion Date"), a

     holder of DECS has the option to convert his DECS, in whole or in part,

     into shares of Columbia common stock, at a conversion rate based on the

     liquidation value of the DECS and the market value of the common stock. If

     the DECS have not already been converted by the holder or redeemed by

     Columbia as described above, all outstanding DECS will convert

     automatically on the Mandatory Conversion Date into shares of common stock

     at the applicable conversion rate.


            3.    Public Offering of Additional Columbia Equity

            In the event that Columbia elects to redeem the Preferred Stock and

     DECS on or prior to the 120th day after the Effective Date and elects to

     fund such redemption through the issuance and sale of up to 16 million

     shares of its common stock or preferred stock, Columbia requests

     authorization for the issuance of such securities, subject to a

     reservation of jurisdiction over the terms of any such issuance and sale

     of common stock and preferred stock.
<PAGE>   18
     C.     Other Proposed Securities Transactions

            1.    Disposition of LESOP Shares

                  Columbia expects to repurchase from the leveraged employee

            stock ownership ("LESOP") portion of the Employees' Thrift Plan

            ("Thrift Plan") of Columbia Gas System all shares ("LESOP Shares")

            held in the common stock fund that have not been allocated to

            employees,(18) to hold the LESOP Shares as treasury shares and to 

            use the LESOP Shares for one or more of the following purposes as

            deemed appropriate by Columbia: (i) to sell the LESOP Shares on the

            open market for cash, (ii) to reissue all or part of the LESOP

            Shares to fund additional requirements under the TCO Guarantee,

            (iii) to reissue all or part of the LESOP Shares to fund the

            Securities Litigation Settlement, as described below, and (iv) to

            fund an employee benefit plan.


            2.    Potential Offering of Columbia Common Stock
                  in Connection with Settlement of Securities Action

                  The Columbia Plan also contemplates Columbia's participation

            in a settlement of securities class action litigation ("Securities

            Litigation Settlement") brought against Columbia, certain present

            and former officers and directors of Columbia and





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

     (18) The Commission authorized Columbia to establish the
LESOP by the order dated February 28, 1990 in Holding Co. Act
Release No. 25047. The LESOP was designed to prefund a portion of
the matching obligation under the terms of the Thrift Plan and to
utilize tax advantages afforded under the Internal Revenue Code.
Columbia proposes, on the Effective Date, that the LESOP be
terminated pursuant to the terms of the Trust Agreement dated as
of October 17, 1991 between Columbia and First Fidelity Bank, N.
A., as Successor Trustee. Columbia will repurchase the LESOP
Shares for cash and at the average price for Columbia common
stock over a specified period preceding the Effective Date. The
proceeds of the repurchase will be paid to the LESOP Debenture
Trustee and, in turn, to the LESOP debentureholders as required
by the LESOP Trust Agreement. The balance would be subject to the
existing guarantee by Columbia and would be paid under the
Columbia Plan.
<PAGE>   19
            Columbia Transmission, the public accounting Firm of Arthur

            Andersen, L.L.P. and certain underwriters for Columbia's 1990

            common stock offering. Pursuant to the Securities Litigation

            Settlement, Columbia and the various other defendants will

            establish a settlement fund of $36.5 million (approximately $16.5

            million of which will be contributed by Columbia) to settle the

            class action claims. The settlement fund will be applied to pay

            District Court-approved counsel fees and costs of administration,

            and the remainder of the fund will be distributed to holders of the

            claims based on acquisitions of Columbia common stock from January

            19, 1990 to June 19, 1991.  The Securities Litigation Settlement is

            conditioned upon the approval of the District Court and the

            Bankruptcy Court.


                  Holders of securities claims may elect, by submitting a form,

            to opt out of the class action and not participate in, or be bound

            by, the Securities Litigation Settlement. In order to preserve any

            securities claims it may have against Columbia, an opt-out

            securities claimant must indicate on its opt-out form that it

            elects to pursue its claim against Columbia in the District Court

            sitting in bankruptcy.  Columbia intends to object to, and/or seek

            estimation of, the claims of opt-out claimants.  If and when such

            claims are allowed, they will he paid by Columbia in Columbia

            common stock valued at then current market prices or, at Columbia's

            option, in cash, or any combination of the two.


                  Columbia seeks Commission authorization to issue Columbia

            common stock, valued at the then current market value, in an

            aggregate amount equal to all allowed
<PAGE>   20
            amounts for opt-out claimants in excess of $1.5 million.

            Authorization for the issuance of Columbia common stock will thus

            commence when the combination of Columbia's contribution to the

            settlement fund and allowed claims of opt-out claimants exceeds $18

            million.  The Securities Litigation Settlement provides for

            termination of the settlement by the defendants in the amount of

            securities as to which opt-out forms have been submitted exceeds an

            undisclosed specified amount.


            D.    Restated Certificate of Incorporation

            The Columbia Plan provides that Columbia's certificate of

     incorporation will he amended and restated ("Restated Certificate of

     Incorporation") in accordance with applicable provisions of the Delaware

     General Corporation Law and the Bankruptcy Code.  The Restated Certificate

     of Incorporation, as more specifically described in the application,

     would, among other things, prohibit the issuance of non-voting equity

     securities as required by the Bankruptcy Code and increase the number of

     authorized shares of preferred (some of which may he issued on and after

     the Effective Date in order to effectuate the Columbia Plan, as described

     above).


            The Restated Certificate of Incorporation also includes various

     provisions that are necessary to permit the issuance of Preferred Stock

     and DECS under the Columbia Plan. These provisions differ from the similar

     provisions in the current Certificate of Incorporation in that they (i)

     decrease the par value of Preferred Stock from fifty dollars ($50) to ten

     dollars ($10); (ii) delete the restriction on common stock dividends and

     amounts of secured debt; (iii) remove and conform specific provisions

     regarding preferred voting
<PAGE>   21
     rights, dividend rights and liquidation rights; and (iv) permit the board

     of directors to determine the specific rights, powers and preferences of

     each series of Preferred Stock, and the limitations thereon, at the time

     of issuance.


IV.  ANALYSIS

     The Columbia Plan requires Commission approval under Section 11(f) of the

Act.(19)  The solicitation of consents or authorizations in respect of the

Columbia Pland is subject to section 11(g) of the Act and rule 62 

thereunder.(20) The issuance by Columbia of New Indenture Securities, DECS, 

Preferred Stock and common stock are subject to sections 6 and 7 of the Act, 

as is Columbia's entering into the Bank Facilities.(21)  The amendment of 

Columbia's Certificate of Incorporation is subject to sections 6, 7 and 12(e) 

of the Act, and rules 62 and 65 thereunder.  The TCO Guarantee and the 

guarantee by Columbia of the payment of the distribution percentage of 

ultimately allowed claims of other unsecured creditors of Columbia Transmission




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

     (19)  Section 11(f) of the Act requires that the Commission
approve a reorganization plan of a registered holding company or
its subsidiary. As noted previously, rule 49(c) exempts the TCO
Plan from the requirement of Commission approval.

     (20)  Section 11(g), in pertinent part, requires, among other
things, that the solicitation of consents or authorizations in
respect of plans be accompanied by such information as the
Commission deems necessary and appropriate in the public interest
or for the protection of investors or consumers, and that such
solicitation be accompanied by "a copy of a report on the plan
which shall be made by the Commission after an opportunity for a
being on the plan . . ., or by an abstract of such report made or
approved by the Commission.

     Columbia requests that the Commission waive the filing of a
separate Form U-R-1, as all the requisite information will be
included in the disclosure statements filed as exhibits to the
application.

     (21)  Rule 49(c) exempts the amendment of the Wilmington Trust
Indenture by Columbia Transmission from the requirements of
sections 6 and 7 of the Act and rule 43 thereunder.
<PAGE>   22
are subject to section 12(b) of the Act and rule 45 thereunder.(22)  Section 9

and 10 of the Act, and rule 43 thereunder are applicable to the acquisition of

TCO Mortgage Bonds by Columbia.  The Commission has reviewed the proposed

transactions and finds that the applicable standards of the Act are satisfied.

Our review has focused in particular on the proposed securities issuances by

Columbia and Columbia's proposed participation in the TCO Plan.


     Columbia projects an 8% average annual growth in operating revenues from

1996 through 1999.  Earnings are expected to increase by more than 4% a year

during this period.  Columbia Transmission projects a 12% annual growth in

earnings over the same four year period.  It appears that the Columbia system

as a whole will be able to achieve a sustained level of financial performance.


     The Commission has generally favored a consolidated debt to equity ratio

of 65%/30% for registered holding companies, the balance generally being

preferred equity.(23)  Assuming that the Effective Date will, in fact, be

December 31, 1995, the ratio of Columbia's consolidated debt to equity is

expected to decline from 65% to 56.7% by 1999.  Columbia's consolidated common

stock equity of 25.5% as of December 31, 1995 is expected to rise to 31% two

years after the




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

     (22)  Rule 45(b)(4) exempts the proposed capital contributions
by Columbia to Columbia Transmission from the requirements of
section 12(b) and rule 45. The repurchase by Columbia of DECS,
Preferred Stock and LESOP Shares is exempt from section 12(c) of
the Act pursuant to Rule 42.

     (23)  This requirement is drawn from section 7(d), which
requires the Commission, in reviewing an issuance of securities,
to consider whether the security is reasonably adapted to the
security structure of the company issuing the security and the
other companies in the registered holding company system.
Holding Co. Act Release No. 25574 (July 7, 1992) (proposing rule
52 under the Act) and cases cited therein.
<PAGE>   23
Effective Date, and to 34.7% by 1999.(24)  The increase is largely attributable

to a projected increase in Columbia's retained earnings. Under the

circumstances, the Commission does not find that Columbia's projections reflect

any excessive leveraging that could affect the Columbia system public-utility

subsidiaries and their consumers, and so require an adverse finding.


     Under the TCO Plan, Columbia would guarantee the payment of all

third-party distributions require under the Plan.  The principal consideration

in this regard is the value of Columbia Transmission's settlement with its

Producers.  Although this amount cannot be precisely quantified at present, it

appears from the general trend of settlement of Producer claims that the

financial exposure to Columbia under the guarantee will not exceed $100

million.  This amount could be financed by internally generated funds and

borrowings under the Bank Facilities.


     In view of these considerations, and on the basis of the record as a

whole, the Commission does not find that any adverse findings are required

under section 7 of the Act. In particular, the Commission does not find that

the security issuances are not reasonably adapted to Columbia's earning power,

or that the guarantees contemplated by the TCO Plan would constitute an
