                         DATED AS OF SEPTEMBER 15, 1994


                 AMENDED AND RESTATED SECURED REVOLVING CREDIT AGREEMENT, dated
as of September 15, 1994, between THE COLUMBIA GAS SYSTEM, INC., a Delaware
corporation (the "Company"), a debtor-in-possession in proceedings under
Chapter 11 of the Bankruptcy Code, and CHEMICAL BANK, a New York banking
corporation (the "Bank", including its successors by merger or otherwise).


                             INTRODUCTORY STATEMENT

                 On July 31, 1991 (the "Filing Date") the Company and its
wholly-owned Subsidiary, Columbia Gas Transmission Corporation ("TCO"), filed
petitions with the United States Bankruptcy Court for the District of Delaware,
initiating proceedings in reorganization under Chapter 11 of Title 11 of the
United States Code.

                 Pursuant to the Secured Revolving Credit Agreement, dated as
of September 23, 1991 (as heretofore amended, supplemented or otherwise
modified, the "Original Agreement"), among the Company, the banks from time to
time parties thereto, and the Bank, as agent for such banks, a senior secured
revolving credit facility in an aggregate principal amount of up to
$275,000,000 was provided by such banks to the Company for the making of
revolving credit loans and for the issuance of Letters of Credit for the
benefit of various insurance companies, state agencies and other entities.

                 Upon request of the Company, the Banks party to the Original
Agreement have reduced their aggregate commitments under the Original Agreement
to $100,000,000.

                 To provide security for the obligations of the Company under
the Original Agreement, the Company provided to the Bank, as agent, certain
Liens on certain property of the Company (as more fully described in the
Original Security Agreement referred to herein) and an allowed administrative
expense claim in the Chapter 11 Case pursuant to Section 364(c)(1) of the
Bankruptcy Code having priority, subject to a Carve-Out (as herein defined),
over all administrative expenses of the kind specified in Sections 503(b) and
507(b) of the Bankruptcy Code.

                 In order to reduce certain fees currently payable under the
Original Agreement, the Company has requested that the Bank and the other banks
party to the Original Agreement agree to amend the Original Agreement to
eliminate the commitments of all banks party thereto other than the Bank, to
release the Liens on certain collateral under the Original Security Agreement
and to provide that the Commitment of the Bank shall be $25,000,000 and shall
be available only for the issuance of Letters of Credit from time to time.

                 Subject to the terms and conditions set forth herein, the Bank
is willing to agree to the Company's request.

         Credit or any Requirement of Law applicable to the Bank or any request
         or directive (whether or not having the force of law) from any

Revision), International Chamber of Commerce Publication No. 400 and, to the
extent not inconsistent therewith, the laws of the State of New York and shall
provide for the fees set forth in Section 2.3 hereof.

                 (b)  If on the Termination Date any Letter of Credit shall be
outstanding, then, upon request of the Bank, the Company shall use its
reasonable best efforts to immediately cause all such outstanding Letters of
Credit to be returned undrawn to the Bank.

                 (c)  Whenever the Company wishes a Letter of Credit to be

maintained for such purpose by the Bank (such request, a "Letter of Credit

the terms of the Letter of Credit Request relating thereto, for the amount of
(i) such draft so paid and (ii) any customary administrative and out-of-pocket
taxes, fees, charges or other costs or expenses incurred by the Fronting Bank
in connection with such payment (each such amount so paid until reimbursed, an
"Unpaid Drawing").  Each such payment shall be made in Dollars and in
immediately available funds to the Bank at its address for notices specified
herein; provided, however, that the Company authorizes the Bank to, and the
Bank agrees that it will, debit the Cash Collateral Account in amounts
sufficient to reimburse the Fronting Bank for any Unpaid Drawings; provided,
further, that the Bank shall not be obligated to withdraw from the Cash
Collateral Account any amount if the balance in the Cash Collateral Account

per annum equal to the Alternate Base Rate plus 3%; it being understood that if
the Bank debits the Cash Collateral Account in amounts sufficient to reimburse
the Fronting Bank for any Unpaid Drawing pursuant to the immediately preceding
sentence, no interest will be paid under this Agreement with respect to such
Unpaid Drawing.

                 (b)  The Company's obligations under this Section 2.2 to
reimburse the Bank with respect to Unpaid Drawings (including, in each case,
interest thereon) shall be absolute and unconditional under any and all
circumstances and irrespective of any set-off, counterclaim or defense to
payment which the Bank or the Company has or has had against any Fronting Bank,
the Bank or any beneficiary or transferee of any Letter of Credit, including,
without limitation, any defense based upon the failure of any drawing under a
Letter of Credit (each a "Drawing") to conform to the terms of the Letter of
Credit or any non-application or misapplication by the beneficiary of the
proceeds of such Drawing; provided, however, that the Company shall not be
obligated to reimburse the Bank for any wrongful payment made by the Fronting
Bank under a Letter of Credit as a result of acts or omissions constituting
willful misconduct or gross negligence on the part of the Fronting Bank.

reduce the Commitment to an amount less than the aggregate Letter of Credit
Outstandings.  If the Commitment is terminated in its entirety, all accrued
commitment fees shall be payable on the effective date of such termination.

                 SECTION 2.5      REQUIREMENTS OF LAW.  In the event that the
Bank or any Fronting Bank shall have determined that any change in any
Requirement of Law regarding capital adequacy or in the interpretation or
application thereof or compliance by the Bank or such Fronting Bank, as the
case may be, with any request or directive regarding capital adequacy (whether
or not having the force of law) from any Governmental Authority made subsequent

on the Bank's or such Fronting Bank's capital, as the case may be, as a
consequence of its obligations hereunder to a level below that which the Bank

(taking into consideration such the Bank's or such Fronting Bank's policies

Fronting Bank, as the case may be, to be material, then from time to time,
after submission by the Bank to the Company, or such Fronting Bank to the Bank
and the Company, of a written request therefor (setting forth the basis of such
claim), the Company shall pay to the Bank, for its own account or the account
of such Fronting Bank, as the case may be, such additional amount or amounts as

at the Bank's office specified in Section 7.1, in Dollars and in immediately
available funds.  If any payment hereunder becomes due and payable on a day
other than a Business Day, such payment shall be extended to the next
succeeding Business Day, and, if such payment that would have otherwise been
due and payable is an Unpaid Drawing, interest thereon shall be payable at the
then applicable rate during such extension.

                 SECTION 2.7       TAXES.  All payments made by the Company
under this Agreement shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on the Bank or any Fronting Bank, as a
result of any present or former connection (excluding a connection arising
solely from the Bank or such Fronting Bank having executed, delivered,
performed its obligations or received a payment under, or enforced, this
Agreement or the other agreements or instruments required to be executed in
connection herewith) between the Bank or such Fronting Bank, as the case may
be, and the jurisdiction of the government or taxing authority imposing such
tax or any political subdivision or taxing authority thereof or therein (all
such non-excluded taxes, levies, imposts, duties, charges, fees, deductions and
withholdings being
   16
                                                                              13



hereinafter called "Taxes").  If any Taxes are required to be withheld from any
amounts payable to the Bank or any Fronting Bank hereunder, the amounts so
payable shall be increased to the extent necessary to yield to the Bank or such
Fronting Bank, as the case may be (after payment of all Taxes), interest or any
such other amounts payable hereunder at the rates or in the amounts specified
in this Agreement.  Whenever any Taxes relating to withholding are payable by
the Company in connection with any Letter of Credit issued hereunder, as
promptly as possible thereafter the Company shall send to the Bank and to the
applicable Fronting Bank (if other than the Bank) a certified copy of an
original official receipt received by the Company showing payment thereof.  If
the Company fails to pay any Taxes when due to the appropriate taxing authority
or fails to remit to the Bank (for its own account or the account of the
applicable Fronting Bank, as the case may be) the required receipts or other
required documentary evidence, the Company shall indemnify the Bank and such
Fronting Bank for any incremental taxes, interest or penalties that may become
payable by the Bank or such Fronting Bank, as the case may be, as a result of
any such failure.  If the Bank or a Fronting Bank shall become aware that it is
entitled to receive a refund in respect of Taxes in respect of which it has
been paid additional amounts by the Company pursuant to this Section 2.6, it
shall promptly notify the Company and the Bank of the availability of such
refund and shall, within 30 days after receipt of a request by the Company,
apply for such refund.  If the Bank or a Fronting Bank receives a refund in
respect of any Taxes in respect of which it has been paid additional amounts by
the Company pursuant to this Section 2.6, it shall promptly notify the Company
and the Bank of such refund and shall, within 30 days after receipt of a
request by the Company (or promptly upon receipt, if the Company has requested
application for such refund pursuant hereto), repay such refund to the Company.
The Bank and any Fronting Bank shall use reasonable efforts to file any
certificate or document if the making of such a filing would avoid the need for
or reduce the amount of any such additional amounts which may thereafter accrue
and would not be disadvantageous to the Bank or such Fronting Bank, as the case
may be.  The agreements in this Section shall survive the termination of this
Agreement and the payment of all amounts payable hereunder.

                 SECTION 2.8  PRIORITY AND LIENS.  (a)  The Company hereby
covenants, represents and warrants that pursuant to Section 364(c)(1) of the
Bankruptcy Code, the Obligations shall constitute allowed administrative
expense claims in the Chapter 11 Case having priority over any and all
administrative expenses of the kind specified in Section 503(b) or 507(b) of
the Bankruptcy Code. Notwithstanding anything to the contrary contained herein,
all of the claims referred to in this Section 2.8(a) and granted in the Chapter
11 Case to the Bank shall be subject in the event of the occurrence of a
Default or an Event of Default, (i) to allowed accrued and unpaid professional
fees and disbursements incurred by the Company and any statutory committee
appointed in the Chapter 11 Case in an amount not to exceed $7,500,000 in the
aggregate to the extent allowed by the Bankruptcy Court (exclusive of
compensation
   17
                                                                              14



previously awarded, whether or not paid) and (ii) to fees pursuant to 28 U.S.C.
Section  1930 (collectively, the "Carve-Out").

                 (b)  The Bank agrees that so long as no Event of Default shall
have occurred, the Company shall be permitted to pay administrative expenses of
the kind specified in Section 503(b) of the Bankruptcy Code incurred in the
ordinary course of the Company's business, and compensation and reimbursement
of expenses allowed and payable under Sections 330 and 331 of the Bankruptcy
Code, as the same may be due and payable, and checks issued therefor shall be
honored upon presentment (to the extent of available funds) and such payments
shall not be applied against the Carve-Out.

                 (c)  The Company hereby covenants, represents and warrants
that, pursuant to Section 364(c)(2) of the Bankruptcy Code, the Obligations
shall at all times be secured by a first priority senior security interest in
and Lien upon all Collateral.

                 SECTION 2.9  RIGHT OF SET-OFF.  Subject to the provisions of
Article VI, upon the occurrence and during the continuance of any Event of
Default, the Bank is hereby authorized at any time and from time to time, to
the fullest extent permitted by law and without further order of or application
to the Bankruptcy Court, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by the Bank to or for the credit or the account
of the Company against any and all of the Obligations of the Company now or
hereafter existing under this Agreement and the Security Agreement,
irrespective of whether or not the Bank shall have made any demand under this
Agreement or the Security Agreement and although such Obligations may be
unmatured.  The Bank agrees promptly to notify the Company after any such
set-off and application made by the Bank; provided that the failure to give
such notice shall not affect the validity of such set-off and application.  The
rights of the Bank under this Section are in addition to other rights and
remedies which the Bank may have upon the occurrence and during the continuance
of any Event of Default.

                 SECTION 2.10  RATING DOWNGRADE; ALTERNATIVE FRONTING BANKS.
(a)  During the continuation of any Rating Downgrade Period, the Borrower may
elect to designate a financial institution other than the Bank (which
institution shall be reasonably acceptable to the Bank) to act as Fronting Bank
with respect to any Letter of Credit requested to be issued during such Rating
Downgrade Period.  If the Company so elects to designate an alternative
Fronting Bank with respect to any Letter of Credit, in lieu of the Letter of
Credit Request otherwise required pursuant to Section 2.1, the Company shall,
at least two Business Days prior to the issuance of such Letter of Credit,
deliver to the Bank the following: (i) the identity of such other Fronting
Bank, (ii) a copy of the letter of credit request submitted to such other
Fronting Bank, (iii) evidence satisfactory to the Bank that the conditions set
forth in Section 2.1(a)(ii), (iii) and (iv) have
   18
                                                                              15



been satisfied with respect to the issuance of such Letter of Credit by such
Fronting Bank and (iv) an executed agreement of such Fronting Bank indicating
that such Fronting Bank has agreed to become bound by the terms of this
Agreement with respect to such Letter of Credit.  Delivery of such documents to
the Bank shall be deemed to constitute a representation and warranty by the
Company that the conditions set forth in Sections 2.1(a)(ii), (iii) and (iv)
and Article III have been satisfied with respect to such Letter of Credit.

                 (b)  If on the Termination Date any Letter of Credit issued by
a Fronting Bank other than the Bank shall be outstanding, then, upon request by
the Bank or such Fronting Bank, the Company shall use its reasonable best
efforts to immediately cause all such outstanding Letters of Credit to be
returned undrawn to such Fronting Bank.  Such Fronting Bank shall promptly
notify the Bank upon receipt of any such returned Letter of Credit.

                 (c)  Immediately upon the issuance by any Fronting Bank other
than the Bank of any Letter of Credit, such Fronting Bank shall be deemed to
have sold and transferred to the Bank, and the Bank shall be deemed irrevocably
and unconditionally to have purchased and received from such Fronting Bank,
without recourse or warranty, a participation in such Letter of Credit equal to
100% of such Fronting Bank's interest in such Letter of Credit, each drawing
made thereunder and the obligations of the Borrower under this Agreement with
respect thereto, and any security therefor.

                 (d)  In the event that any Drawing is made under any Letter of
Credit issued by a Fronting Bank other than the Bank, upon notice by such
Fronting Bank to the Bank of such Drawing and of the amount of the Unpaid
Drawing with respect thereto, the Bank shall promptly and unconditionally pay
to the Fronting Bank the amount of such Unpaid Drawing in Dollars and in
immediately available funds.  If the Fronting Bank so notifies the Bank prior
to 11:00 A.M, New York City time, on any Business Day, the Bank shall make
available to such Fronting Bank the amount of such payment on such Business
Day.  If and to the extent the Bank shall not make such amount available to the
Fronting Bank on a timely basis, the Bank agrees to pay to the Fronting Bank
forthwith on demand, such amount (together with interest thereon for each day
from such date until the date such amount is paid to the Fronting Bank at the
Federal Funds Effective Rate).  The Bank shall also pay to the Fronting Bank,
prior to 3:00 P.M. on the date when such amounts are due from the Company, all
amounts payable by the Company to such Fronting Bank pursuant to Section
2.3(d).  The Bank shall also pay to the Fronting Bank, within one Business Day
of receipt thereof from the Company, all other amounts received from the
Company for the account of such Fronting Bank pursuant to the terms hereof.

                 (e)  Upon the request of the Bank, each Fronting Bank shall
furnish to the Bank copies of any Letter of Credit to which
   19
                                                                              16



such Fronting Bank is party and such other documentation as may reasonably be
requested by the Bank.

                 (f)  The obligations of the Bank to make payments to each
Fronting Bank with respect to Letters of Credit issued by such Fronting Bank
shall be irrevocable and not subject to any qualification or exception
whatsoever and shall be made in accordance with the terms and conditions of
this Agreement under all circumstances, including, without limitation, any of
the following circumstances:

                       (i)   any lack of validity or enforceability of this
         Agreement;

                      (ii)   the existence of any claim, set-off, defense or
         other right which the Company may have at any time against a
         beneficiary named in a Letter of Credit, any transferee of any Letter
         of Credit (or any Person for whom any such transferee may be acting),
         the Fronting Bank or any other Person, whether in connection with this
         Agreement, any Letter of Credit, the transactions contemplated herein
         or any unrelated transactions (including any underlying transaction
         between the Company and the beneficiary named in any such Letter of
         Credit);

                     (iii)   any draft, certificate or any other document
         presented under the Letter of Credit proving to be forged, fraudulent,
         invalid or insufficient in any respect or any statement therein being
         untrue or inaccurate in any respect;

                      (iv)   the surrender or impairment of any security for
         the performance or observance of any of the terms of this Agreement or
         the Final Order; or

                       (v)   the occurrence of any Default or Event of Default.

                 (g)  Each Fronting Bank hereby irrevocably designates and
appoints the Bank as its agent to receive payments on its behalf pursuant to
Section 2.2 or 2.3 and to take action with respect to the Collateral and any
other collateral security existing from time to time securing payment of the
Obligations, and to exercise such powers and perform such duties as are
reasonably incidental thereto.  The Bank reserves the right, in its sole
discretion in each instance, to exercise or refrain from exercising any rights
or remedies which the Bank may have under the Security Agreement, including,
without limitation, the right to foreclose and sell and otherwise deal with, or
refrain from foreclosing and selling or otherwise dealing with any Collateral
or any other collateral security existing from time to time securing payment of
the Obligations or to enforce, or refrain from enforcing, the Security
Agreement, and no Fronting Bank shall be entitled to exercise any rights
thereunder.  The Security Agreement and all Collateral shall be held by the
Bank in its name, but to the extent of any Fronting Bank's interest in the
Letters of Credit in accordance with this Agreement, the Bank agrees that the
Collateral and the Security
   20
                                                                              17



Agreement shall be held by the Bank as agent for such Fronting Bank.

                 (h)  The Bank shall not have any duties or responsibilities to
any Fronting Bank, except those expressly set forth in this Section 2.10, or
any fiduciary relationship with any Fronting Bank, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or the Security Agreement.  Neither the Bank nor any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates shall
be liable for any action lawfully taken or omitted to be taken by it or such
person under or in connection with this Agreement, the Security Agreement or
any document delivered pursuant hereto or thereto, except that it or such
person shall be liable for its or such person's own gross negligence or willful
misconduct.

                 (i)  Each Fronting Bank severally agrees to indemnify the Bank
against all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind whatsoever which
may at any time be imposed on, incurred by or asserted against the Bank
relating to the gross negligence or willful misconduct, or alleged gross
negligence or willful misconduct, of such Fronting Bank.

   25
                                                                              22



omitted to state any fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading; the
projections contained therein were prepared in good faith and represented at
the time they were furnished, the Company's best estimate of the information
purported to be shown therein, and the Company is not aware of any information
that would lead it to believe that such projections or other information are
misleading in any material respect.

                 SECTION 4.5  LITIGATION.  Other the Chapter 11 Case or as
otherwise disclosed to the Bank in writing prior to the date hereof, there is
no (a) injunction, stay, decree or order issued by any court or arbitrator or

pending against, or to the knowledge of the Company threatened against or
affecting, the Company or any of its Subsidiaries (other than TCO) before any
court or arbitrator or any governmental body, agency or official which could
reasonably be expected to have a Material Adverse Effect.

                 SECTION 4.6  SECURITY INTEREST.  The Final Order and the
Security Agreement will create and grant to the Bank a valid, first priority
perfected and enforceable security interest in and lien upon the Collateral,
securing the Obligations, superior in right to any other Liens, existing or
future, which the Company or any creditors thereof or any other Person, may
have against such Collateral or interests therein, other than Permitted Liens.

"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

nor any Subsidiary is in violation or in default under any term or provision of
any charter, by-law, statute, rule, regulation, judgment, decree, order, writ
or injunction applicable to it, such that such violations or defaults in the
aggregate could reasonably be expected to have a Material Adverse Effect.
Neither the Company nor any of its Subsidiaries (other than TCO) is a party to
any agreement or instrument or subject to any legislative or charter or other
corporate restriction or any judgment, order, writ, injunction, decree, rule or
regulation materially and adversely affecting the business, operations,
properties or assets or the financial condition of the Company or its
Subsidiaries (other than TCO), taken as a whole.

                 SECTION 4.9  NO DEFENSES.  The Company is truly and justly
indebted to the Bank for the Obligations, and does not currently have, and
agrees that it will not at any time hereafter assert, any defense, offset or
counterclaim with respect to the reimbursement of amounts drawn under Letters
of Credit, except as such defense offset or counterclaim relates to the gross
negligence or willful misconduct of the Bank.

documents described in such index promptly upon request by the Bank or the
Bank's counsel.

                 SECTION 5.6  CORPORATE EXISTENCE; NO CHANGE IN BUSINESS.  The
