                                     PART I
 
ITEM 1. BUSINESS
 
     The principal business of Southern Natural Gas Company ("Southern"), which
is a wholly owned subsidiary of Sonat Inc. ("Sonat"), is the transmission of
natural gas in interstate commerce. Southern, including its subsidiaries, owns
approximately 9,230 miles of interstate pipeline. Its pipeline system has a
certificated daily delivery capacity of approximately 2.4 billion cubic feet
("Bcf") of natural gas. Southern's pipeline system extends from gas fields in
Texas, Louisiana, Mississippi, Alabama, and the Gulf of Mexico to markets in
Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, and
Tennessee. Southern also has pipeline facilities offshore Texas connecting gas
supplies to other pipelines that transport such gas to Southern's system. A map
of Southern's pipeline system, including pipelines of its subsidiaries, appears
on page I-8.
 
     Southern owns and operates Muldon Storage Field ("Muldon"), a large
underground natural gas storage field in Mississippi connected to its pipeline
system. Based on operating experience, Southern recently sought to have the
working storage capacity of Muldon reduced from 52 to 31 billion cubic feet of
gas. The Federal Energy Regulatory Commission ("FERC") approved this reduction
for a one-year period ending November 1, 1994, subject to a further review of
Muldon's operations during the 1993-94 winter period.
 
     Bear Creek Storage Company ("Bear Creek"), an unincorporated joint venture
between wholly owned subsidiaries of Southern and Tenneco Inc., each of which is
a 50-percent participant, owns a large underground natural gas storage field
located in Louisiana that is operated by Southern and provides storage service
to Southern and Tennessee Gas Pipeline Company, a subsidiary of Tenneco Inc. The
Bear Creek Storage Field has a total certificated working storage capacity of
approximately 65 billion cubic feet of gas, half of which is committed to
Southern. At December 31, 1993, Bear Creek's gross facilities cost was
approximately $246,923,000 and its participants' equity was $90,907,000.
Southern had an investment in Bear Creek, including its equity in undistributed
earnings, of $45,453,000 at December 31, 1993.
 
     Under the terms of Order No. 636, discussed below, effective November 1,
1993, Southern commenced providing contract storage services as part of its
unbundled and restructured services. Consequently, most of Southern's working
storage capacity at Muldon and its half of Bear Creek are now used for such
services. As a part of making this new service available, effective November 1,
1993, Southern sold at its cost $123 million of its working storage gas
inventory to its new storage customers.
 
     Southern's interstate pipeline business is subject to regulation by the
FERC, the U.S. Department of Energy's Economic Regulatory Administration (the
"ERA"), and the U.S. Department of Transportation under the terms of the Natural
Gas Policy Act of 1978 (the "NGPA"), the Natural Gas Act, and various pipeline
safety and environmental laws. See "Governmental Regulation" below for
information concerning the regulation of natural gas transmission operations.
 
     Southern's business is subject to the usual operating risks associated with
the transmission of natural gas through a pipeline system, which could result in
property damage and personal injury. Sonat maintains broad insurance coverage on
behalf of Southern limiting financial loss resulting from these operating risks.
 
     Additional business information concerning Southern and its wholly owned
subsidiaries is contained in Management's Discussion and Analysis of Financial
Condition and Results of Operations and in the Notes to Consolidated Financial
Statements in Part II of this report and is hereby incorporated herein by
reference.
 
     At January 1, 1994, Southern and its subsidiaries employed approximately
1,170 persons.
 
     Southern's principal executive offices are located at 1900 Fifth Avenue
North, AmSouth-Sonat Tower, Birmingham, Alabama 35203, and its telephone number
is (205) 325-7410.

Order No. 636 Restructuring
 
     In 1992 the FERC issued its Order No. 636 (the "Order"). As required by the
Order, interstate natural gas pipeline companies, including Southern and South
Georgia Natural Gas Company ("South Georgia"), a wholly owned interstate
pipeline subsidiary of Southern, have made significant changes in the way they
operate. The Order required pipelines, among other things, to (1) separate
(unbundle) their sales, transportation, and storage services; (2) provide a
variety of transportation services, including a "no-notice" service pursuant to
which the customer is entitled to receive gas from the pipeline to meet
fluctuating requirements without having previously scheduled delivery of that
gas; (3) adopt a straight-fixed-variable method for rate design (which assigns
more costs to the demand component of the rates than do other rate-design
methodologies previously utilized by pipelines); and (4) implement a pipeline
capacity release program under which firm customers have the ability to "broker"
the pipeline capacity for which they have contracted. The Order also authorizes
pipelines to offer unbundled sales services at market-based rates and allows for
pregranted abandonment of some services.
 
     Interstate pipeline companies, including Southern, are incurring certain
costs ("transition costs") as a result of the Order, the principal one being
costs related to amendment or termination of existing gas purchase contracts,
which are referred to as gas supply realignment ("GSR") costs. The Order
provides for the recovery of 100 percent of the GSR costs and other transition
costs to the extent the pipeline can prove that they are eligible, that is,
incurred as a result of customers' service choices in the implementation of the
Order, and were incurred prudently.
 
     In its restructuring settlement discussions, Southern has advised its
customers that the amount of GSR costs that it actually incurs will depend on a
number of variables, including future natural gas and fuel oil prices, future
deliverability under Southern's existing gas purchase contracts, and Southern's
ability to renegotiate certain of these contracts. While the level of GSR costs
is impossible to predict with certainty because of these numerous variables,
based on current spot-market prices, a range of estimates of future oil and gas
prices, and recent contract renegotiations, the amount of GSR costs would be
approximately $275-$325 million on a present-value basis. This amount includes
the payments made to amend or terminate gas purchase contracts described below.
 
     On September 3, 1993, the FERC generally approved a compliance plan for
Southern and directed Southern to implement its restructured services pursuant
to the Order on November 1, 1993 (the "September 3 order"). Pursuant to
Southern's compliance plan, GSR costs that are eligible for recovery include
payments to reform or terminate gas purchase contracts. Where Southern can show
that it can minimize transition costs by continuing to purchase gas under the
contract (i.e., it is more economic to continue to perform), eligible GSR costs
would also include the difference between the contract price and the higher of
(a) the sales price for gas purchased under the contract or (b) a price
established by an objective index of spot-market prices. Recovery of these
latter costs is permitted for an initial period of two years.
 
     Southern's compliance plan contains two mechanisms pursuant to which
Southern is permitted to recover 100 percent of its GSR costs. The first
mechanism is a monthly fixed charge designed to recover 90 percent of the GSR
costs from Southern's firm transportation customers. The second mechanism is a
volumetric surcharge designed to collect the remaining ten percent of such costs
from Southern's interruptible transportation customers. This funding will
continue until the GSR costs are fully recovered or funded. The FERC also
indicated that Southern could file to recover any GSR costs not recovered
through the volumetric surcharge after a period of two years. In addition,
Southern's compliance plan provides for the recovery of other transition costs
as they are incurred and any remaining transition costs may be recovered through
a regular rate filing. Southern's customers have generally opposed the recovery
of its GSR costs.
 
     The September 3 order rejected the argument of certain customers that a
1988 take-or-pay recovery settlement bars Southern from recovering GSR costs
under gas purchase contracts executed before March 31, 1989, which comprise most
of Southern's GSR costs. Those customers subsequently filed motions urging the
FERC to reverse its ruling on that issue. On December 16, 1993, the FERC
affirmed its September 3 ruling with respect to the 1988 take-or-pay recovery
settlement (the "December 16 order"). The December 16 order generally approved
Southern's restructuring tariff submitted pursuant to the September 3 order.
Various parties have filed motions urging the FERC to modify the December 16
order and have sought judicial review
 
                                       I-2
<PAGE>   5
 
of the September 3 order. Southern and its customers engaged in settlement
discussions regarding Southern's restructuring filing prior to the September 3
order, but the parties were unable to reach a settlement. Those discussions are
continuing.
 
     During 1993 Southern reached agreements to reduce significantly the price
payable under a number of high cost gas purchase contracts in exchange for
payments of approximately $114 million. On December 1, 1993, Southern filed with
the FERC to recover such costs and approximately $3 million of prefiling
interest (the "December 1 filing"). On December 30, 1993, the FERC accepted such
filing to become effective January 1, 1994, subject to refund, and subject to a
determination through a hearing before an administrative law judge that such
costs were prudently incurred and eligible under Order No. 636. Southern's
customers are opposing its recovery of these GSR costs in this proceeding. The
December 30 order rejected arguments of various parties that a pipeline's
payments to affiliates, in this case Southern's payment to a subsidiary of Sonat
Exploration Company, that represented approximately $34 million of the December
1 filing, may not be recovered under Order No. 636.
 
     In December 1993 Southern reached agreement to reduce the price under
another contract in exchange for payments having a present value of
approximately $52 million. Payments will be made in equal monthly installments
over an eight-year period ending December 31, 2001. On February 14, 1994,
Southern made a rate filing to recover, beginning March 1, 1994, those costs as
well as approximately $2 million of other settlement costs and $800,000 of
prefiling interest. Southern also incurred approximately $17.5 million of GSR
costs, plus prefiling interest, from November 1, 1993, through January 31, 1994,
from continuing to purchase gas under contracts that are in excess of current
market prices. On March 1, 1994, Southern made a rate filing to recover those
costs beginning April 1, 1994. Southern plans to make additional rate filings
quarterly to recover these "price differential" costs and any other GSR costs.
 
     Southern is unable to predict all of the elements of the ultimate outcome
of its Order No. 636 restructuring proceeding, its settlement discussions with
its customers regarding all of the pending issues arising in connection with the
proceeding, or its rate filings to recover its transition costs.
 
     In requiring that Southern provide unbundled storage service, the Order
resulted in a substantial reduction of Southern's working storage gas inventory
and consequently a reduction in its rate base. This reduction was effective on
November 1, 1993, when Southern restructured pursuant to the Order and sold at
its cost $123 million of its working storage gas inventory to its customers. The
Order also resulted in rates that are less seasonal, thereby shifting revenues
and earnings for Southern out of the winter months.
 
Markets -- Transportation and Sales
 
     As described above, effective November 1, 1993, Southern and South Georgia
restructured their services in compliance with FERC Order No. 636 by separating
their transportation, storage, and merchant services. With the exception of some
limited sales necessary to dispose of its gas supply remaining under contract,
Southern essentially became solely a transporter of natural gas. Effective May
5, 1992, South Georgia had converted all its sales service to
transportation-only service and Southern had begun to provide a gas sales
service to South Georgia's former sales customers.
 
     Southern transports or sells gas at wholesale for distribution for
domestic, commercial, and industrial uses to nine gas distributing companies, to
114 municipalities and gas districts, and to nine connecting interstate pipeline
companies. Southern also transported or sold gas directly to 55 industrial
end-users in 1993. Southern principally transports gas to resale and industrial
customers and to other pipelines, sells some limited volumes of gas at wholesale
for distribution, and sells very minimal volumes of gas directly to industrial
customers. The principal industries served directly by Southern's pipeline
system and indirectly through its resale customers' distribution systems include
the chemical, pulp and paper, textile, primary metals, stone, clay and glass
industries.
 
     Transportation volumes in 1993 were 763 Bcf or 91 percent of Southern's
total throughput of 836 Bcf, compared with 733 Bcf or 87 percent of Southern's
total 1992 throughput of 842 Bcf. Sales to resale distribution customers,
including municipalities and gas districts, accounted for virtually all of 1993
sales of
 
                                       I-3
<PAGE>   6
 
73 Bcf (excluding the sale of storage inventory) and 1992 sales of 109 Bcf.
Southern's sales to direct sales customers and interstate pipeline companies in
both years were negligible. Southern had sales of 19 Bcf during November and
December 1993 (following implementation of its Order No. 636 restructuring) that
were made at receipt points where the gas entered its pipeline system;
consequently, those volumes are included within the 763 Bcf of transportation
volumes for 1993.
 
     Transportation service is rendered by Southern for its resale customers,
direct industrial customers and other end-users, gas producers, other gas
pipelines, and gas marketing and trading companies. Southern provides
transportation service in both its gas supply and market areas. Transportation
service is provided under rate schedules that are subject to FERC regulatory
authority. Rates for transportation service depend on whether such service is on
a firm or interruptible basis and the location of such service on Southern's
pipeline system. Transportation rates for interruptible service (i.e., service
of a lower priority than firm transportation) are charged for actual volumes
transported. Firm transportation service also includes a demand charge designed
so that the customer pays for a significant portion of the service each month
based on a contract demand volume regardless of the actual volume transported.
Rates for transportation service are discounted by Southern in individual
instances to respond to competition in the markets it serves. Continued
discounting could, under certain circumstances, increase the risk that Southern
may not recover all of its costs allocated to transportation services.
 
     Sales by Southern are anticipated to continue only until Southern's
remaining supply contracts expire, are terminated, or are assigned. As a result
of Order No. 636 Southern is attempting to terminate its remaining gas purchase
contracts through which it had traditionally obtained its long-term gas supply.
Some of these contracts contain clauses requiring Southern either to purchase
minimum volumes of gas under the contract or to pay for it ("take-or-pay"
clauses). Although Southern currently is incurring essentially no take-or-pay
liabilities under these contracts, the annual weighted average cost of gas under
these contracts is in excess of current spot-market prices. Pending the
termination of these remaining supply contracts, Southern has agreed to sell a
portion of its remaining gas supply to a number of its firm transportation
customers for a one-year term that began November 1, 1993. Recently, the sales
agreements with Atlanta Gas Light Company and its subsidiary, Chattanooga Gas
Company (collectively "Atlanta") were extended through March 31, 1995. The rest
of Southern's remaining supply will be sold on a month-to-month basis. Southern
will file to recover as a GSR cost pursuant to Order No. 636 the difference
between the cost associated with the gas supply contracts and the revenue from
the sale agreements and month-to-month sales and also any cost incurred to
reduce the price under or to terminate Southern's remaining gas supply
contracts.
 
     When long-term sales service agreements with substantially all of
Southern's resale customers expired or were terminated in 1989, Southern entered
into a series of short-term agreements on an annual basis with virtually all of
such customers. Prior to the implementation of Order No. 636, several customers
had already reduced their firm sales contract demand volumes or converted a
portion of their firm sales volumes to firm transportation volumes. From 1988
until Southern's implementation of Order No. 636, total daily delivery
obligations under firm sales contracts (the "contract demand" upon which monthly
demand charges are based) were reduced by approximately 689 million cubic feet
("MMcf") from their level at the end of 1987 of approximately 2.1 Bcf. Prior to
Southern's implementation of Order No. 636, approximately 74 percent of this
reduction had been replaced with firm transportation volumes under contracts of
varying terms and durations, which also provided for fixed monthly charges.
 
     In accordance with the September 3 order approving Southern's Order No. 636
compliance plan, Southern solicited service elections from its customers in
order to implement its restructured services on November 1, 1993. Southern's
largest customer, Atlanta, bid for firm transportation service on Southern at
prices significantly below Southern's filed tariff rates. Southern rejected
Atlanta's bids. Southern and Atlanta subsequently entered into an interim
agreement under which Atlanta signed firm transportation service agreements with
transportation demands of 582 million cubic feet per day for a minimum term of
four months beginning November 1, 1993, and 118 million cubic feet per day for a
term extending until April 30, 2007, at the maximum FERC-approved rates. This
represented an aggregate reduction of 100 million cubic feet per day from
Atlanta's level of service prior to November 1, 1993. In January 1994 Atlanta
provided notice that it had elected to continue that level of firm service until
October 31, 1994. Southern's other customers elected in
 
                                       I-4
<PAGE>   7
 
aggregate to obtain an amount of firm transportation services that represented a
slight increase from their level of firm sales and transportation services from
Southern prior to Southern's implementation of Order No. 636, at the maximum
FERC-approved tariff rates, for terms ranging from one to ten or more years.
 
     Although management believes that most of Southern's former resale
customers ultimately will commit to some type of new long-term firm
transportation agreements with Southern under its restructuring program, it is
unable to predict at what total volume level or for what duration such
commitments will be made.
 
     Transportation and sales by Southern to three unaffiliated distribution
customers, Atlanta, Alabama Gas Corporation, and South Carolina Pipeline
Corporation, accounted for approximately 40 percent, 18 percent, and nine
percent, respectively, of Southern's 1993 consolidated revenues. Atlanta and
Alabama Gas Corporation were the only two customers that accounted for ten
percent or more of Southern's consolidated revenues for 1993.
 
     Southern is continuing to pursue growth opportunities to expand the level
of services in its traditional market area and to connect new gas supplies. On
May 13, 1993, Southern and South Georgia received approval from the FERC for a
$27 million expansion of South Georgia's pipeline system into northern Florida
and southwestern Georgia that will increase firm daily capacity by 40 million
cubic feet per day. Construction on this project is under way and should be
completed in mid-1994. In January 1994 Southern reached tentative agreement with
a group of new customers to expand its service in the growing eastern Tennessee
area. The proposed project entails a 20-mile pipeline extension that would
deliver approximately nine million cubic feet of natural gas per day to a
delivery point near Chattanooga.

gas, see Management's Discussion and Analysis of Financial Condition and Results
of Operations contained in Part II of this report.
 
Gas Supplies
 
     During 1993 Southern purchased its gas supply from the following areas: 51
percent from southern Louisiana and from the Gulf of Mexico, offshore Louisiana,
and Texas; three percent from northern Louisiana and Texas; and 46 percent from
Mississippi and Alabama. Southern has approximately 60 gas purchase contracts
remaining with gas producers that commit proved recoverable reserves to
Southern. As described above, pursuant to Order No. 636, Southern is attempting
to terminate its remaining gas purchase contracts.
 
     The following table contains information as to Southern's gas supply and
the general sources from which that supply was obtained during the years 1991
through 1993.

* As used in this report, the term "Mcf" means thousand cubic feet; the term
  "MMcf" means million cubic feet; and the term "Bcf" means billion cubic feet.
  All volumes of natural gas referred to in this report are stated at a pressure
  base of 14.73 pounds per square inch absolute ("psia") and at 60 degrees 
  Fahrenheit.
 
     Southern entered into no new long-term gas purchase agreements in 1993, due
to the cessation of its merchant role because of Order No. 636 as discussed
above. Since Order No. 636 prohibits Southern from providing its traditional
bundled merchant service, Southern does not anticipate at this time that it will
need to contract for the long-term purchase of any additional natural gas
supplies in the future. Southern will purchase minimal volumes of gas from time
to time as may be required for system management purposes. Southern does expect,
however, that adequate gas supplies will need to continue to be available to its
system; consequently, Southern has continued its efforts to have new gas
supplies attached to its system.

Potential Royalty Claims
 
     In connection with its settlements of take-or-pay claims made by producers
over the past few years, Southern has in certain limited instances indemnified,
to varying degrees, the producer from certain potential claims made by royalty
owners. Southern has thus far been notified of 12 potential royalty claims under
the indemnity provisions of various settlement agreements. The claims for which
Southern may have to indemnify these producers have been asserted by both
private lessors with respect to onshore leases and the Minerals Management
Service Division of the U.S. Department of the Interior (the "MMS") with respect
to offshore and Indian leases. Southern settled four of these claims during 1993
for approximately $1.2 million.
 
     In addition to the claims for which Southern has been put on notice, it is
possible that other producers may make future claims against Southern for
royalty indemnification. The June 26, 1992 decision of the Louisiana Supreme
Court in Frey v. Amoco, in which the court held that royalty was due on
take-or-pay payments, may form a basis for royalty claims for a share of
take-or-pay settlements by private lessors in Louisiana and in other states that
may follow the Frey decision. Because courts typically require that interest be
paid on the royalty back to the date of settlement, the amount owed can
substantially exceed the royalty amount. Management believes that Southern's
maximum exposure under all of its various royalty indemnities in onshore
take-or-pay settlements, including interest, approximates $15 million.
Management is unable to state whether any additional royalty claims based on
Southern's indemnification provisions in its take-or-pay settlements will be
asserted or to predict the outcome of any such claims or resulting litigation.
 
     In addition to the potential royalty claims related to onshore production,
Southern also faces exposure in connection with indemnifications in take-or-pay
settlements with producers who have federal offshore or Indian leases. The MMS
issued a policy statement and guidelines on May 3, 1993, declaring its intention
to collect royalty payments for contract buy-downs, buy-outs, pricing disputes,
and on any portion of take-or-pay settlement payments that are subject to future
recoupment. In June 1993 the MMS began to issue letters to producers requiring
payment of royalty on all such payments received under take-or-pay settlements,
along with interest back to the date of payment. The MMS has been aggressively
auditing producers since this time and issuing orders to pay. A lawsuit filed by
the Independent Petroleum Association of America against the MMS and others
challenging the validity of the MMS' new policy is pending in federal district
court for the District of Columbia. Management is unable to predict the outcome
of this litigation or the ultimate outcome of any collection efforts by the MMS.
 
     Management believes that Southern's maximum exposure for all royalty claims
related to offshore production, including interest, approximates $10 million if
no recovery from its customers is allowed. Under the terms of a 1988 take-or-pay
recovery settlement with Southern's customers, Southern is entitled to seek
recovery of these costs under the FERC's Order No. 500 cost-sharing procedures.
The customers, however, are entitled to challenge any effort by Southern to
recover those costs. Management is unable to predict the outcome of the efforts
of the MMS to collect royalty on a portion of any offshore settlement or of
Southern's efforts to recover any amounts it may ultimately pay from its
customers.
 
     Southern believes that it is adequately reserved for any royalty claims
that it may ultimately have to pay or to settle and that, in any event, such
claims will not have a material adverse effect on its financial condition or
results of operations.
 
Southern Energy Company
 
     Southern Energy Company ("Southern Energy"), a wholly owned subsidiary of
Southern, owns a liquefied natural gas ("LNG") receiving terminal near Savannah,
Georgia, which was constructed for a project, now terminated, to import LNG from
Algeria. The terminal has been inactive since the early 1980s. On July 22, 1992,
the FERC issued an order approving a settlement relating to Southern Energy's
LNG facilities. The settlement resolved a number of outstanding rate and
accounting issues on a favorable basis and preserved an option for customers of
Southern Energy to obtain LNG through this facility at least through the year
1999.

Sea Robin Pipeline Company
 
     For many years Southern was a 50-percent participant, through a wholly
owned subsidiary, with a wholly owned subsidiary of United Gas Pipe Line Company
("United"), in Sea Robin Pipeline Company ("Sea Robin"), an unincorporated gas
supply pipeline joint venture. Sea Robin was originally constructed to obtain
Gulf of Mexico gas supplies for Southern's and United's respective pipeline
systems and was operated by United. In December 1990 Southern, through a newly
formed subsidiary, acquired the 50-percent interest in Sea Robin formerly owned
by the subsidiary of United. As a result of the acquisition, two wholly owned
subsidiaries of Southern own 100 percent of Sea Robin, which is now being
operated by Southern. Sea Robin has a 436-mile pipeline system located in the
Gulf of Mexico through which it transports gas for others under its
FERC-regulated tariffs. Sea Robin is a transportation-only pipeline that has
restructured in compliance with FERC Order No. 636. Sea Robin's compliance
filing has been accepted by the FERC. Sea Robin transported approximately 287
Bcf of natural gas in 1993. These Sea Robin volumes are included within the
Southern transportation volumes discussed earlier. See Note 8 of the Notes to
Consolidated Financial Statements in Part II of this report for additional
information regarding Sea Robin.
 
Competition and Current Business Conditions
 
     The natural gas transmission industry, although regulated, is very
competitive. During the period from the mid-1980s until the Order No. 636
restructuring, customers had switched much of their volumes from a bundled
merchant service to transportation service, reflecting an increased willingness
to rely on gas supply under unregulated arrangements. Southern competes with
several pipelines for the transportation business of its customers and at times
discounts its transportation rates in order to maintain market share. Southern
continues to provide a limited merchant service with gas supply remaining under
contract and, in this capacity, competes with other suppliers, pipelines, gas
producers, marketers, and alternate fuels.
 
     Natural gas is sold in competition principally with fuel oil, coal,
liquefied petroleum gases, and electricity. An important consideration in
Southern's markets is the ability of natural gas to compete with alternate
fuels. Residual fuel oil, the principal competitive alternate fuel in Southern's
market area, was at certain times in 1993, and currently is, priced at or below
the comparable price of natural gas in industrial and electric generation
markets. Some parts of Southern's market area are also served by one or more
other pipeline systems that can provide transportation as well as sales service
in competition with Southern. Southern's two largest customers are both able to
obtain a portion of their natural gas requirements through transportation by
other pipelines.

Governmental Regulation
 
     Southern is subject to regulation by the FERC and by the Secretary of
Energy under the Natural Gas Act, the NGPA, and the Department of Energy
Organization Act of 1977 (the "DOE Act"). Southern's operating subsidiaries are
also subject to such regulation.
 
     The Natural Gas Act, modified by the DOE Act, grants to the FERC authority
to regulate the construction and operation of pipeline and related facilities
utilized in the transportation and sale of natural gas in interstate commerce,
including the extension, enlargement, or abandonment of such facilities.
Southern and its operating subsidiaries hold required certificates of public
convenience and necessity issued by the FERC authorizing them to construct and
operate all pipelines, facilities, and properties now in operation for which
certificates are required, and to transport and sell natural gas in interstate
commerce.
 
     The FERC also has authority to regulate the transportation of natural gas
in interstate commerce and the sale of natural gas in interstate commerce for
resale. Although the FERC still retains jurisdiction over their resale rates,
following the implementation of Order No. 636, Southern and other interstate
pipeline companies are now permitted to charge market-based rates for gas sold
in interstate commerce for resale. Gas sold by marketing companies is not
regulated by the FERC. Transportation rates remain fully regulated. The price at
which gas is sold to direct industrial customers is not subject to the FERC's
jurisdiction. As necessary, Southern and its operating subsidiaries file with
the FERC applications for changes in their transportation rates and charges
designed to allow them to recover fully their costs of providing such service to
their customers, including a reasonable rate of return. These rates are normally
allowed to become effective, subject to refund, until such time as the FERC
rules on the actual level of rates. See "Rate and Regulatory Proceedings" below.
 
     The Natural Gas Wellhead Decontrol Act of 1989, enacted on July 26, 1989,
phased in decontrol of the wellhead price of all gas then remaining subject to
maximum lawful price limitations by January 1, 1993. Thus, the price of all gas
sold at the wellhead is no longer regulated.
 
     Regulation of the importation of natural gas is vested in the Secretary of
Energy, who has delegated various aspects of this import jurisdiction to the
FERC and the ERA.
 
     Southern and its operating subsidiaries are subject to the Natural Gas
Pipeline Safety Act of 1968, as amended, which regulates pipeline and LNG plant
safety requirements, and to the National Environmental Policy Act and other
environmental legislation. Southern and its operating subsidiaries have a
continuing program of inspection designed to keep all of their facilities in
compliance with pollution control and pipeline safety requirements and believe
that they are in substantial compliance with applicable requirements. Southern's
capital expenditures to comply with environmental and pipeline safety
regulations were approximately $14 million in 1993. It is anticipated that such
expenditures will be approximately $11 million in 1994 and approximately $10
million in 1995. For more information regarding environmental matters, see the
discussion below.
 
     Rate and Regulatory Proceedings.  Various matters pending before the FERC,
or before the courts on appeal from the FERC, relating to, or that could affect,
Southern or one or more of its subsidiaries are described in Part II of this
report in Note 8 of the Notes to Consolidated Financial Statements and in
Management's Discussion and Analysis of Financial Condition and Results of
Operations, which are incorporated herein by reference. As described in Note 8,
several general rate changes have been implemented by Southern and remain
subject to refund.
 
Environmental Matters
 
     Southern and certain of its subsidiaries are subject to extensive federal,
state, and local environmental laws and regulations that affect their
operations. Governmental authorities may enforce these laws and regulations with
a variety of civil and criminal enforcement measures, including monetary
penalties, assessment and remediation requirements, and injunctions as to future
activities. Southern and certain of its subsidiaries' use and disposal of
hazardous materials and toxic substances are subject to the requirements of the
federal Toxic Substances Control Act ("TSCA") and the federal Resource
Conservation and Recovery
 
                                       I-9
<PAGE>   12
 
Act ("RCRA"), among others, and comparable state and local statutes. The
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"),
also known as "Superfund," imposes liability, without regard to fault or the
legality of the original act, for release of a "hazardous substance" into the
environment.
 
     Southern is named as a potentially responsible party ("PRP") at three
Superfund sites, at two of which it is a de minimis party. Based on the number
of other financially responsible PRPs at each of the sites, the estimated
relative volume of material contributed to the sites by Southern, the
information that it currently possesses regarding the expected costs required to
remediate the sites, and the amounts already contributed to remediation,
Southern currently estimates that it should not ultimately be required to
contribute in excess of $200,000 in the aggregate to the costs of remediation of
all three sites.
 
     In addition, Southern has been advised by a joint defense group of PRPs
("JDG") at another Superfund site that the JDG might seek to add it as a PRP,
but Southern has received no notification from the Environmental Protection
Agency ("EPA") asserting that it is a PRP. Southern has been informed by
representatives of the JDG that no characterization of soil or groundwater
contamination at this site has yet taken place and, therefore, the extent of
such contamination, if any, is not currently known. Southern has thus far
elected not to join the JDG, because it believes that it has significant
potential defenses to liability for this site and that, in any event, it shipped
de minimis amounts of material to this site. Based on the number of other
financially responsible PRPs and other information that it currently possesses,
Southern currently estimates that it will not incur liabilities related to this
site in an amount material to Southern.
 
     Liability under CERCLA (and applicable state law) can be joint and several
with other PRPs. Although volumetric allocation is a factor in assessing
liability, it is not necessarily determinative; thus, the ultimate liability at
any of these sites could be substantially greater than the amounts described
above. Southern does not believe that its status as a PRP at any of these sites
will have a material adverse effect on its financial condition or results of
operations.
 
     Southern has in the past used lubricating oils containing polychlorinated
biphenyls ("PCBs") in conjunction with auxiliary compressed air systems at
Southern's natural gas compressor stations. Although the use of such oils was
discontinued in the early 1970's, Southern has discovered residual PCB
contamination at certain of its gas compressor station sites. For some time,
Southern has had an ongoing internal project to identify and deal with the
presence of PCBs at these sites. A total of thirteen stations evidenced some
level of on-site PCB contamination ranging from low to moderate. Southern has
completed the characterization and clean-up of twelve of these sites based on
the guidelines of the TSCA at a total cost of approximately $6 million. Southern
has partially completed the characterization and clean-up of the remaining site
and believes that it should be able to complete the remediation of this site for
a total cost of less than $5 million.
 
     In the operation of their natural gas pipeline systems, Southern and South
Georgia have used, and continue to use at several locations, gas meters
containing elemental mercury. Many of these meters have been removed from
service. Southern and South Georgia plan to remove the remaining mercury meters
during the course of regularly scheduled facilities upgrades, but until such
time, the meters are handled pursuant to established procedures that protect
employees and comply with Occupational Safety and Health Administration
standards. It is generally believed in the natural gas pipeline industry that,
in the course of normal maintenance and replacement operations, elemental
mercury may have been released from mercury meters. Although at this time
neither the EPA nor any state in which Southern or South Georgia operates has
yet issued clean-up levels or guidelines with respect to contamination from past
releases or spills of mercury, Southern expects that guidelines will be
forthcoming. Southern and South Georgia have nonetheless begun preliminary
efforts to address this situation and plan to begin remediation if contamination
is detected upon characterization of these sites. Because the number of sites
involved and the extent of contamination at any site are not yet known, Southern
is unable at this time to estimate the cost of remediation. Based on its
experience with other remediation projects, the industry experience to date with
remediation of mercury, and its preliminary analysis of the possible extent of
the contamination, however, Southern believes that its remediation of any
mercury contamination will not have a material adverse effect on its financial
condition or results of operations.
 
                                      I-10
<PAGE>   13
 
     Southern generally considers environmental assessment and remediation costs
and costs associated with compliance with environmental standards incurred by
Southern and South Georgia to be recoverable through rates since they are
prudent costs incurred in the ordinary course of business and, accordingly, will
seek recovery of such costs through rate filings, although no assurance can be
given with regard to their ultimate recovery.
 
     Southern and its subsidiaries are subject to the federal Clean Air Act and
the federal Clean Air Act Amendments of 1990 ("1990 Amendments"), which added
significantly to the existing requirements established by the federal Clean Air
Act. The 1990 Amendments require that the EPA issue new regulations, mainly
related to mobile sources, air toxics, ozone non-attainment areas, acid rain,
permitting, and enhanced monitoring. While it will not be possible to estimate
the additional costs of compliance with these new requirements until the EPA and
the states complete their regulations, management expects that the regulations
when issued may require significant capital spending to modify certain of the
facilities of Southern and its subsidiaries, particularly with regard to
modifications that may be required for certain natural gas compressor stations
to reduce their emission of oxides of nitrogen.
 
     In the opinion of management, based on information currently possessed by
Southern, the probability is remote that Southern or any of its subsidiaries
will incur a liability as a result of the presently identified environmental
contingencies described above in an amount material to Southern. While the
nature of environmental contingencies makes complete evaluation impractical,
Southern is currently aware of no other environmental matter that could
reasonably be expected to have a material impact on its results of operations or
financial condition. Southern has an active and ongoing environmental program at
all levels of its organization and believes responsible environmental management
is integral to its business. Southern believes that it and its subsidiaries have
conducted their operations in substantial compliance with applicable
environmental laws and regulations governing their activities.

     A description of Southern's and its subsidiaries' properties is included

ITEM 3. LEGAL PROCEEDINGS
 
     For information regarding certain proceedings pending before federal
regulatory agencies, see Note 8 of the Notes to Consolidated Financial
Statements in Part II of this report.
 
     Arcadian Corporation v. Southern Natural Gas Company and Atlanta Gas Light
Company was filed in January 1992 in the U.S. District Court for the Southern
District of Georgia. In this lawsuit against Southern and Atlanta Gas Light
Company for alleged violation of the antitrust laws in connection with
Southern's refusal to provide direct service to the Plaintiff, Arcadian
Corporation ("Arcadian"), Arcadian claims actual damages of at least $15
million, which could be trebled under the antitrust laws. Southern and Arcadian
executed an agreement settling this lawsuit on November 30, 1993. The settlement
provides that the lawsuit will be dismissed with prejudice upon final,
nonappealable approval by the FERC of the direct connection and transportation
service requested by Arcadian. Pending such approval, the lawsuit has been
stayed. While management believes it has meritorious defenses and intends to
defend the suit vigorously if the stay were to be lifted, given the inherently
unpredictable nature of litigation and the relatively early state of discovery
in the case, management is unable to predict the ultimate outcome of the
proceeding if it were to go forward, but believes that it will not have a
material adverse effect on Southern's financial position.
 
     Exxon Corporation v. Southern Natural Gas Company was filed in February
1994 in the U.S. District Court for the Southern District of Texas. Exxon
Corporation ("Exxon"), the plaintiff in this suit, asked the court to declare
that Southern has no right to terminate a gas purchase contract with Exxon
providing for the sale and purchase of gas produced from Mississippi Canyon and
Ewing Bank Area Blocks, offshore Louisiana (the "Contract"), which Southern gave
notice of termination effective March 1, 1994. In the alternative, Exxon alleged
that Southern has repudiated and breached the Contract and asked for an
unspecified amount
 
                                      I-11
<PAGE>   14
 
of monetary damages. Management is unable to predict the outcome of this
litigation and whether its position that it has the right to terminate this
contract will be sustained.
 
     Southern and its subsidiaries are involved in several other lawsuits, all
of which have arisen in the ordinary course of business. Southern does not
believe that any ultimate liability resulting from any of these other pending
lawsuits will have a material adverse effect on the financial position or
results of operations of Southern.

        and Results of Operations

                          SOUTHERN NATURAL GAS COMPANY
               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

        Southern Natural Gas Company and its subsidiaries (Southern)
participate in the interstate transmission and sale of natural gas in the
southeastern United States and are regulated by the Federal Energy Regulatory
Commission (FERC).  The natural gas transmission industry, although regulated,
is very competitive.  Effective November 1, 1993, Southern separated its
transportation, storage and merchant services to comply with Order No. 636 (see
following discussion) and essentially became solely a gas transporter.  Even
before the Order No. 636 restructuring, customers had switched much of their
volumes from a bundled merchant service to transportation service, reflecting
an increased willingness to rely on gas supply under unregulated arrangements.
Southern competes with several pipelines for the transportation business of its
customers and at times discounts its transportation rates in order to maintain
market share.  Although it is now predominantly a transporter of gas, Southern
continues to provide a limited merchant service with gas supply remaining under
contract and, in this capacity, competes with other suppliers, gas producers,
marketers and alternate fuels.

        Southern is pursuing growth opportunities to expand the level of
services in its traditional market area and to connect new gas supplies.  South
Georgia Natural Gas Company, a wholly owned subsidiary of Southern, received
approval from the FERC on May 13, 1993, for an expansion of its pipeline system
into northern Florida and southwestern Georgia that will increase firm daily
capacity by 40 million cubic feet per day.  Construction on this project is
under way and should be completed by mid-1994.  Southern has entered into an
agreement in principle to expand its system to Chattanooga, Tennessee.

</TABLE>

        1993 Versus 1992.  Southern's operating results for 1993 were down
primarily due to a favorable settlement of $9.6 million in 1992 relating to
Southern Energy Company's idle liquified natural gas (LNG) facility.  A
settlement at Sea Robin Pipeline Company increased 1993 results by $4.5
million.  General and administrative expenses were up in 1993 due to a $4
million increase in health insurance expense and an increase in stock-based
employee compensation.

        Gas sales revenue and gas cost increased at Southern due to the sale of
$123 million of storage gas inventory pursuant to the implementation of Order
No. 636 on November 1, 1993.  Total market throughput increased 2 percent;
however, Order No. 636 resulted in a shift in volumes from sales to market
transportation.  Supply transportation volumes decreased due to competition
from other pipelines.

        1992 Versus 1991.  Operating income for 1992 includes the effect of a
favorable settlement of $9.6 million relating to Southern Energy's LNG
facility, while 1991 was negatively affected by one-time charges totaling $11
million related to a cost-containment program and the cancellation of the
Mobile Bay project.  Excluding these items, operating income was lower
primarily as a result of a $7 million increase in stock-based employee
compensation.

        Southern's total volumes increased 8 percent in 1992.  Market
throughput was higher because of colder weather and new markets, offsetting the
loss of a competitive load to coal that was served in 1991 when gas prices were
substantially lower and losses to other pipeline competition.  The 18 percent
increase in supply transportation is primarily the result of higher
deliverability and an aggressive program of hooking up new gas supply to the
Sea Robin system.

ORDER NO. 636

        In 1992 the FERC issued its Order No. 636 (the Order).  As required by
the Order, interstate natural gas pipeline companies have made significant
changes in the way they operate.  The Order required pipelines, among other
things, to: (1) separate (unbundle) their sales, transportation and storage
services; (2) provide a variety of transportation services, including a "no-
notice" service pursuant to which the customer will be entitled to receive gas
from the pipeline to meet fluctuating requirements without having previously
scheduled delivery of that gas; (3) adopt a straight fixed variable (SFV)
method for rate design (which assigns more costs to the demand component of the
rates than do other rate design methodologies previously utilized by
pipelines); and (4) implement a pipeline capacity release program under which
firm customers will have the ability to "broker" the pipeline capacity for
which they have contracted.  The Order also authorizes pipelines to offer
unbundled sales services at market-based rates and allowed for pregranted
abandonment of some services.

        As discussed in Note 8 of the Notes to Consolidated Financial
Statements, Southern is incurring certain transition costs as a result of
implementing Order No. 636, and for Southern, those are primarily gas supply
realignment (GSR) costs relating to existing gas purchase contracts.  In its
restructuring settlement discussions, Southern has advised its customers that
the amount of GSR costs that it actually incurs will depend on a number of
variables, including future natural gas and fuel oil prices, future
deliverability under Southern's existing gas purchase contracts and Southern's
ability to renegotiate certain of these contracts.  While the level of GSR
costs is impossible to predict with certainty because of these numerous
variables, based on current spot-market prices, a range of estimates of future
oil and gas prices, and recent contract renegotiations, the amount of GSR costs
would be approximately $275 million-$325 million on a present value basis.
This includes the $168 million of settlements discussed below.

        In requiring that Southern provide unbundled storage service, the Order
resulted in a substantial reduction of Southern's working storage gas inventory
and consequently a reduction in its rate base.  The reduction in rate base was
effective on November 1, 1993, when Southern restructured pursuant to the Order
and sold $123 million of its storage gas inventory to its customers.  The Order
also resulted in rates that are less seasonal, thereby shifting revenues and
earnings for Southern out of the winter months.

        The FERC issued an order on September 3, 1993 (the September 3 order),
that generally approved a compliance plan for Southern and directed it to
implement restructured services on November 1, 1993.  In accordance with the
September 3 order, Southern solicited service elections from its customers in





                                      II-5
<PAGE>   20
order to implement its restructure services on November 1, 1993.  Southern's
largest customer, Atlanta Gas Light Company and its subsidiary, Chattanooga Gas
Company (collectively Atlanta), bid for firm transportation service on Southern
at prices significantly below Southern's filed tariff rates.  Southern rejected
Atlanta's bids.  Southern and Atlanta subsequently entered into an interim
agreement under which Atlanta signed firm transportation service agreements
with transportation demands of 582 million cubic feet per day for a minimum
term of four months beginning November 1, 1993, and 118 million cubic feet per
day for a term extending until April 30, 2007, at the maximum FERC-approved
rates.  This represented an aggregate reduction of 100 million cubic feet per
day from Atlanta's level of services prior to November 1, 1993.  In January
1994, Atlanta provided notice that it had elected to continue that level of
firm service until October 31, 1994.  Southern's other customers elected in
aggregate to obtain an amount of firm transportation services that represented
a slight increase from their previous level of firm sales and transportation
services from Southern, at the maximum FERC-approved tariff rates, for terms
ranging from one to 10 or more years.

        Southern is unable to predict all of the elements of the ultimate
outcome of its Order No. 636 restructuring proceeding, its settlement
discussions with Atlanta and its other customers, and the limited rate filings
to recover its transition costs.

NATURAL GAS SALES AND SUPPLY

        As a result of Order No. 636, Southern is attempting to terminate its
remaining gas purchase contracts through which it had traditionally obtained
its long-term gas supply.  Some of these contracts contain clauses requiring
Southern either to purchase minimum volumes of gas under the contract or to pay
for it (take-or-pay clauses).  Although Southern currently is incurring
essentially no take-or-pay liabilities under these contracts, the annual
weighted average cost of gas under these contracts is in excess of current
spot-market prices.  Pending the termination of these remaining supply
contracts, Southern has agreed to sell a portion of its remaining gas supply to
a number of its firm transportation customers for a one-year term which began
November 1, 1993.  The rest of Southern's remaining supply will be sold on a
month-to-month basis.  The difference between the cost associated with the gas
supply contracts and the revenue from the sale agreements and month-to-month
sales should be recoverable as a GSR cost pursuant to Order No. 636.  In
addition, any cost to terminate or reduce the price under Southern's remaining
contracts should also be recoverable as a GSR cost pursuant to Order No. 636.

      During 1993 Southern reached agreements to reduce significantly the price
payable under a number of high-cost gas purchase contracts in exchange for
payments with a present value of approximately $168 million.

        Southern's purchase commitments under its remaining gas supply
contracts for the years 1994 through 1998 are estimated as follows:

       1995                                                  150

       These estimates are subject to significant uncertainty due both to the
number of assumptions inherent in these estimates and to the wide range of
possible outcomes for each assumption.  None of the three major factors which
determine purchase commitments (underlying reserves, future deliverability and
future price) is known today with certainty.  As explained above, Southern
expects to recover all of these costs, including its costs to terminate these
purchase commitments, either through the sale of the gas or as a GSR cost.

RATE MATTERS

       Several general rate changes have been implemented by Southern and
remain subject to refund.  See Note 8 of the Notes to Consolidated Financial
Statements for a discussion of rate matters.

        1993 Versus 1992.  Interest income was higher in 1993 due to an
increase in average levels and rates on notes from affiliates.  The increase in
interest income was largely offset by an increase in accrued interest expense
of $8 million provided on certain income tax issues and to higher average debt
levels.

        1992 Versus 1991.  Interest expense on debt increased due to an
increase in average debt outstanding, resulting from the restructuring of
Southern's capital structure in May 1992, partially offset by lower average
interest rates.

        1993 Versus 1992.  Net cash provided by operating activities increased
due to the sale of storage gas inventory pursuant to Order No. 636 and lower
cash outflows relating to gas imbalances.  Partially offsetting the increase
were GSR payments of approximately $128 million made in 1993.

        1992 Versus 1991.  Net cash provided by operating activities decreased
as a result of lower cash outflows relating to gas imbalances.

        1993 Versus 1992.  Net cash used in financing activities increased
slightly due to scheduled loan repayments.  Southern did not refinance any debt
during 1993.

<PAGE>   23
        1992 Versus 1991.  Net cash used in financing activities in 1992 was
flat with 1991.  In May 1992, Southern completed the restructuring of its
capital structure by issuing $100 million in Notes and dividending the proceeds
to Sonat.  As a result, the debt to capitalization ratio increased 8 percent
when compared to December 31, 1991.

CAPITAL EXPENDITURES

        Capital expenditures for 1994, including joint ventures, are expected
to be approximately $68 million, primarily for pipeline additions and
replacements and other projects, some of which have not yet received regulatory
approval.

LIQUIDITY AND CAPITAL RESOURCES

        At December 31, 1993, Southern had available $50 million under lines of
credit.  Southern expects to use cash from operations, borrowing in the public
or private markets or loans from affiliates to finance future capital or other
corporate expenditures.

INFLATION AND THE EFFECT OF CHANGING ENERGY PRICES

        Although the rate of inflation in the United States has been moderate
over the past several years, its potential impact should be considered when
analyzing historical financial information.  In past times of high general
inflation, oil and gas prices have increased at comparable, and at times,
higher rates.  The changing regulatory environment in which the natural gas
business operates, along with other competitive factors, would currently make
it difficult to increase prices enough to recover significantly higher costs of
operations.  Southern's results of operations will be affected by future
changes in domestic and international oil and gas prices and the
interrelationship between oil, gas and other energy prices.

ENVIRONMENTAL ISSUES

        Southern is involved in various environmental compliance and cleanup
activities, and has been notified that it is one of many potentially
responsible parties at certain federal Superfund sites.  Southern does not
expect costs relating to these activities, including any responsibility for
cleanup of such sites, to be material, taken either separately or in the
aggregate, with respect to the financial position or results of operations of
Southern.

        In addition, Southern has taken steps to test for the presence of
polychlorinated biphenyls (PCB) at its natural gas compressor stations.  A
total of 13 stations evidenced some level of on-site PCB contamination ranging





                                      II-9
<PAGE>   24
from low to moderate.  Southern has completed the characterization and cleanup
of 12 of these sites at a cost of approximately $6 million.  Southern has
partially completed the characterization and cleanup of the 13th site and
believes that it should be able to complete the remediation of this site for a
total cost of less than $5 million, approximately half of which had been
incurred at December 31, 1993.

        Southern generally considers environmental assessment and remediation
costs and costs associated with compliance with environmental standards to be
recoverable through rates since they are prudent costs incurred in the ordinary
course of business, and accordingly, will seek recovery of such costs through
rate filings, although no assurance can be given with regard to their ultimate
recovery.

        Southern has an active and ongoing environmental program and believes
responsible environmental management is integral to its business.

Item 8.  Financial Statements and Supplementary Data

Report of Ernst & Young, Independent Auditors


The Board of Directors
Southern Natural Gas Company

We have audited the accompanying consolidated balance sheets of Southern
Natural Gas Company and Subsidiaries as of December 31, 1993 and 1992, and the
related statements of income, changes in retained earnings and cash flows for
each of the three years in the period ended December 31, 1993.  Our audits also
included the financial statement schedules listed in the Index at Item 14(a)2.
These financial statements and schedules are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
financial statements and schedules based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Southern Natural
Gas Company and Subsidiaries at December 31, 1993 and 1992, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1993, in conformity with generally
accepted accounting principles.  Also, in our opinion, the related financial
statement schedules, when considered in relation to the basic financial
statements taken as a whole, present fairly in all material respects the
information set forth therein.

                 SOUTHERN NATURAL GAS COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.      Significant Accounting Policies

        Principles of Consolidation - The Consolidated Financial Statements
include the accounts of Southern Natural Gas Company and its subsidiaries,
which is a wholly owned subsidiary of Sonat Inc.  Intercompany transactions and
accounts have been eliminated in consolidation.  The equity method of
accounting is used for investments in joint ventures owned 50 percent or less.

        Certain amounts in the 1992 and 1991 Consolidated Financial Statements
have been reclassified to conform with the 1993 presentation.

        Inventories - At December 31, 1993, inventories consist primarily of
materials and supplies, and are carried at cost.

        Gas Imbalance Receivables and Payables - Gas imbalances represent the
difference between gas receipts from and gas deliveries to Southern's
transportation and storage customers.  Gas imbalances arise when these
customers deliver more or less gas into the pipeline than they take out.  Under
the provisions of Order No. 636, these amounts are settled monthly.

        Plant, Property and Equipment, and Depreciation - Plant, property and
equipment is carried at cost.  Southern generally provides for depreciation on
a composite basis.  (See Note 5.)

        Revenue Recognition - Southern recognizes revenue from both natural gas
sales and transportation in the period the service is provided.  Reserves are
provided on revenues collected subject to refund when appropriate.

        Income Taxes - Southern and its subsidiaries file federal income tax
returns on a consolidated basis with its parent and other members of its
affiliated group.  For financial statement purposes, income taxes are provided
as though Southern and its subsidiaries file separate income tax returns;
however, those companies incurring losses are allocated the tax benefit of such
losses due to the consolidated return.

        Southern and its subsidiaries follow an asset and liability approach in
accounting for income taxes.  Deferred tax assets and liabilities are
determined using the tax rate for the period in which those amounts are
expected to be received or paid.

       Lines of Credit and Credit Agreement - As part of Sonat's cash
management program, Southern regularly loans funds to or borrows funds from
Sonat.  Notes receivable and payable are in the form of demand notes with rates
reflecting Sonat's return on funds loaned to its subsidiaries, average
short-term investment rates and cost of borrowed funds.  In certain
circumstances, these notes are subordinated in right of payment to amounts
payable by Sonat under certain long-term credit agreements.

       On May 31, 1993, Southern renewed its short-term lines of credit of $50
million for a period of 364 days.  Borrowings are in the form of unsecured
promissory notes and bear interest at rates based on the banks' prevailing
prime, international or money-market lending rates.

7.      Income Taxes (Cont'd)

        Consolidated income tax expense is different from the amount computed
by applying the U.S. federal income tax rate to income before income tax.  The
reasons for this difference are as follows:

       The effect of the deferred tax rate increase to 35 percent due to the
Omnibus Budget Reconciliation Act of 1993 has been reduced by the effect of the
reduction of liabilities established for excess deferred income taxes expected
to be returned over future periods to customers.

       Rate Matters - Periodically, Southern and its subsidiaries file general
rate filings with the FERC to provide for the recovery of cost of service and a
return on equity.  The FERC normally allows the filed rates to become
effective, subject to refund, until it rules on the approved level of rates.
Southern and its subsidiaries provide reserves relating to such amounts
collected subject to refund, as appropriate, and make refunds upon
establishment of the final rates.

       On September 1, 1989, Southern implemented new rates, subject to refund,
reflecting a general rate decrease of $6 million.  In January 1991, Southern
implemented new rates, subject to refund, that restructured its rates
consistent with a FERC policy statement on rate design and increased its sales
and transportation rates by approximately $65 million annually.  These two
proceedings have been consolidated for hearing.  On October 7, 1993, the
presiding administrative law judge certified to the FERC a contested offer of
settlement pertaining to the consolidated rate cases which (1) resolved all
outstanding issues in the rate decrease proceeding, (2) resolved the cost of
service, throughput, billing determinant and transportation discount issues in
the rate increase proceeding, and (3) provided a method to resolve all other
issues in the latter proceeding, including the appropriate rate design.  On
December 16, 1993, the FERC issued an order (December 16 Order) approving the
settlement, but with modifications.  On December 22, 1993, Southern filed a
letter with the FERC that outlined certain objections with respect to the
FERC's modifications to the terms and conditions of the settlement.  Southern
advised the FERC that the December 16 Order undercut the economic compromise
achieved in the settlement.  Southern also filed a request for rehearing of the
December 16 Order but is unable to determine at this time if or to what extent
rehearing will be granted by the FERC.

       On September 1, 1992, Southern implemented another general rate change.
The rates reflected the continuing shift in the mix of throughput volumes away
from sales and toward transportation and a $5 million reduction in annual
revenues.  On April 30, 1993, Southern submitted a proposed settlement in the
proceeding which, if approved by the FERC, would resolve the throughput and
certain cost of

service issues.  On June 4, 1993, the presiding administrative law judge
certified the settlement to the FERC.  In another order issued on December 16,
1993, the FERC also approved this settlement, but with modifications.  Southern
objects to these modifications and has also requested rehearing of this order,
but is unable to determine at this time if rehearing will be granted by the
FERC.

       In 1992 Southern placed in service certain facilities constructed to
connect to its pipeline system gas reserves produced from certain Mississippi
Canyon and Ewing Bank Area Blocks, offshore Louisiana.  By order dated May 15,
1991, the FERC had authorized Southern, subject to certain conditions affecting
Southern's ability to include the cost of the facilities in its rates, to
construct and operate the pipeline, compression, and related facilities
necessary to connect these reserves.  Southern sought rehearing of the
unacceptable certificate conditions, but in an order issued on January 13,
1993, the FERC left intact the conditions contained in its 1991 order.  It
deferred the specific application of the conditions to Southern's pending rate
case implemented September 1, 1992.  The certificate order itself is now on
appeal.  Southern is unable to predict the ultimate rate treatment of the $45
million cost of these facilities, but does not expect such treatment to have a
material adverse effect on its financial position.

       On May 1, 1993, Southern implemented a general rate change, subject to
refund, which increased its sales and transportation rates by approximately $57
million annually.  The filing is designed to recover increased operating costs
and to reflect the impact of competition on both Southern's level and mix of
services.  A hearing regarding various cost allocation and rate design issues
in this proceeding is set for June 14, 1994.

       Sea Robin Pipeline Company has previously filed under the provisions of
Order No. 500 to recover $83.1 million in gas purchase contract settlement
payments from its former pipeline sales customers, Koch Gateway Pipeline
Company, successor to United Gas Pipe Line Company (United), and Southern.
Those filings remain subject to refund pending the outcome of any prudence
challenges in the proceedings.  Although the eligibility issues have been
resolved, one party has reserved its rights to challenge prudence until such
time as certain take-or-pay allocation issues are resolved with respect to the
flow-through of costs billed to United.

       Southern is authorized to flow through to its jurisdictional customers
$38.1 million of the costs allocated to it by Sea Robin as well as the $32.7
million in Order No. 500 costs allocated to it by United.  Southern's
flow-through of United and Sea Robin's costs remains subject to refund pending
the outcome of any challenges to the costs or allocation of the costs in those
pipelines' Order No. 500 proceedings.  Southern does not believe that the
outcome of any such challenges will have a material adverse effect on its
financial position.

8.     Commitments and Contingencies (Cont'd)

       On July 2, 1993, the FERC issued an order reaffirming its approval of
the non-take-or-pay aspects of a settlement filed by United in 1988, which
included Southern's phased abandonment of its contract demand with United.  The
order rejected the take-or-pay aspects of the settlement, including United's
proposed Order No. 528 allocation methodology.  As a consequence, various
parties that had originally supported the settlement are now contesting it.
United has evidenced its intention to honor the non-take-or-pay aspects of the
1988 settlement and has induced several of the parties to withdraw their
judicial appeals of the July 2 order.  Southern does not believe that the final
resolution of this matter will have a material adverse effect on its financial
position.

       Gas Purchase Contracts - Gas purchase contract settlement payments
(other than the gas supply realignment payments discussed below) made by
Southern and not previously recovered or expensed are included on the
Consolidated Balance Sheet at December 31, 1993, in "Current Assets".  Pursuant
to a final and nonappealable FERC order, Southern is entitled to collect these
amounts from its customers over the remainder of a five-year period which
commenced May 1, 1989.  Southern currently is incurring essentially no
take-or-pay liabilities under its gas purchase contracts.  Southern regularly
evaluates its position relative to gas purchase contract matters, including the
likelihood of loss from asserted or unasserted take-or-pay claims or
above-market prices.  When a loss is probable and the amount can be reasonably
estimated, it is accrued.

       Order No. 636 - In 1992 the FERC issued its Order No. 636 (the Order).
The Order requires significant changes in interstate natural gas pipeline
services.  Interstate pipeline companies, including Southern, are incurring
certain costs (transition costs) as a result of the Order, the principal one
being costs related to amendment or termination of existing gas purchase
contracts, which are referred to as gas supply realignment (GSR) costs.  The
Order provides for the recovery of 100 percent of the GSR costs and other
transition costs arising out of the implementation of the Order to the extent
that the pipeline can prove that they were prudently incurred.  Numerous
parties have appealed the Order to the Circuit Courts of Appeal.

       On September 3, 1993, the FERC generally approved a compliance plan for
Southern and directed Southern to implement its restructured services pursuant
to the Order on November 1, 1993 (the September 3 order).  Pursuant to
Southern's compliance plan, GSR costs that are eligible for recovery include
payments to reform or terminate gas purchase contracts or, for contracts where
Southern can show that it can minimize transition costs by continuing to
purchase gas under the contract (i.e., it is more economic to continue to
perform), the difference between the contract price and the higher of (a) the
sales price for gas purchased under the contract, or (b) a price established by
an objective index of spot-market prices.  Recovery of these latter costs is
permitted for an initial period of two years.

       Southern's compliance plan contains two mechanisms pursuant to which
Southern is permitted to recover 100 percent of its GSR costs.  The first
mechanism is a monthly fixed charge designed to recover 90 percent of the GSR
costs from Southern's firm transportation customers.  The second mechanism is a
volumetric surcharge designed to collect the remaining 10 percent of such costs

from Southern's interruptible transportation customers.  This funding will
continue until the GSR costs are fully recovered or funded.  The FERC also
permitted Southern to file to recover any GSR costs not recovered through the
volumetric surcharge after a period of two years.  In addition, Southern's
compliance plan provides for the recovery of other transition costs as they are
incurred and any remaining transition costs may be recovered through a regular
rate filing.

       The September 3 order rejected the argument of certain customers that a
1988 take-or-pay recovery settlement bars Southern from recovering GSR costs
under gas purchase contracts executed before March 31, 1989.  Those customers
have filed motions urging the FERC to reverse its ruling on that issue.  On
December 16, 1993, the FERC affirmed its September 3 ruling with respect to the
1988 take-or-pay recovery settlement.  The December 16 Order generally approved
Southern's restructuring tariff submitted pursuant to the September 3 order.
Various parties have filed motions urging the FERC to modify the December 16
Order and have sought judicial review of the September 3 order.  Southern and
its customers engaged in settlement discussions regarding Southern's
restructuring filing prior to the September 3 order, but the parties were
unable to reach a settlement.  Those discussions are continuing.

       During 1993 Southern reached agreements to reduce significantly the
price payable under a number of high cost gas purchase contracts in exchange
for payments of approximately $114 million.  On December 1, 1993, Southern
filed to recover such costs and approximately $3 million of prefiling interest.
On December 30, 1993, the FERC accepted such filing to become effective January
1, 1994, subject to refund, and subject to a determination that such costs were
prudently incurred and eligible under Order No. 636.  The December 30 order
rejected arguments of various parties that a pipeline's payments to affiliates,
which represented approximately $34 million of the December 1, 1993 filing, may
not be recovered under Order No. 636.

       In December 1993, Southern reached agreement to reduce the price under
another contract in exchange for payments having a present value of
approximately $52 million which is included in "Deferred Credits and Other" in
the Consolidated Balance Sheet.  Payments will be made in equal monthly
installments over an eight-year period ending December 31, 2001.  Southern
expects to make a limited rate filing by mid-February 1994 to recover such
costs beginning April 1, 1994.  Southern has also incurred approximately $11
million of costs during November and December 1993 from continuing to purchase
gas under contracts that are in excess of current market prices.  Southern will
make additional rate filings to recover these costs quarterly.  The total costs
of $180 million accrued through December 31, 1993, are included in current and
long-term gas supply realignment costs in the Consolidated Balance Sheet.

       Southern is unable to predict all of the elements of the ultimate
outcome of its Order No. 636 restructuring proceeding, its settlement
discussions with its customers, and the limited rate filings to recover its
transition costs.

10.     Employee Benefit Plans

        Retirement Plans - Sonat has a trusteed, non-contributory, tax
qualified defined benefit retirement plan (the Retirement Plan) covering
substantially all employees of Southern.  A supplemental benefit plan (the
Supplemental Plan) that provides retirement benefits in excess of those allowed
under Sonat's tax qualified retirement plan is also in effect.  Benefits under
the plans are based on a combination of years of service and a percentage of
compensation.  Benefits are vested over five years.

        Sonat determines the amount of funding to the Retirement Plan on a
year-to-year basis, with amounts consistent with minimum and maximum funding
requirements established by various governmental bodies.

        Southern's net periodic pension cost consists of the following
components:

        Until July 1993, Sonat set aside assets in fixed income securities such
that values of those assets equal or exceed the present value of benefit
obligations to current retirees (immunized obligations).  After that date, a
separate immunized portfolio has not been maintained.  The assumed rates used
to measure the projected benefit obligations and the expected earnings of plan
assets are:

        Other Post Employment Benefits - Southern participates in plans of
Sonat that provide for postretirement health care and life insurance benefits
to its employees when they retire.  Southern adopted Statement of Financial
Accounting Standards (SFAS) No. 106, "Employers' Accounting for Postretirement
Benefits Other Than Pensions," for all plans as of January 1, 1993.  SFAS No.
106 requires companies to accrue the cost of postretirement health care and
life insurance benefits within the employees' active service periods.  Southern
has elected to amortize the transition obligation over a 20-year period.
Southern previously expensed the cost of its retiree medical benefits as they
were paid. Expense for retiree life insurance benefits was recognized as
Southern funded its Retiree Life Insurance Plan.

        The annual net periodic cost for postretirement health care and life
insurance benefits for the year ended December 31, 1993, includes the following
components:

        Prior to the adoption of SFAS No. 106, the cost of providing health
care and life insurance benefits was $3.9 million in 1992 and 1991.

        Southern implemented rates effective May 1, 1993, which provide for the
recovery of its SFAS No. 106 costs.  Costs incurred in 1993 prior to that date,
amounting to $2.6 million, were deferred to be amortized over a three-year
period commencing when Southern's next rate case becomes effective.

10.     Employee Benefit Plans (Cont'd)

        Southern funds its Retiree Life Insurance Plan with the amount of
funding determined on a year-to-year basis with the objective of having assets
equal plan liabilities.  In addition, during 1993 Southern initiated funding of
postretirement health care benefits in an amount generally equal to its SFAS
No. 106 expense.

        The following table sets forth the funded status at December 31, 1993,
and at the date of SFAS No. 106 adoption, January 1, 1993, for Southern's

        The rate of increase in the per capita costs of covered health care
benefits is assumed to be 12.3 percent in 1994, decreasing gradually to 6
percent by the year 2002.  Increasing the assumed health care cost trend rate
by 1 percentage point would increase the accumulated postretirement benefit
obligation as of December 31, 1993, by approximately $7.5 million and increase
the service cost and interest cost components of the net periodic
postretirement benefit cost by approximately $.6 million.

10.     Employee Benefit Plans (Cont'd)

        Executive Award Plan - Sonat has an Executive Award Plan that provides
awards to certain key employees in the form of stock options, restricted stock,
and stock appreciation rights (SARs) in tandem with any or all stock options.
In years prior to 1991, tax offset payments were also generally provided in
conjunction with these awards.  SARs permit the holder of an exercisable option
to surrender that option for an amount equal to the excess of the market price
of the common stock on the date of exercise over the option price
(appreciation).  The appreciation is payable in cash, common stock, or a
combination of both.  SARs are subject to the same terms and conditions as the
options to which they are related.  No SARs have been issued since 1990.  At
December 31, 1993, 75,000 SARs were outstanding to employees of Southern.
Sonat issued 7,000 shares of restricted stock to employees of Southern during
1993.  The shares generally vest 10 years from the date of grant, unless the
closing price of Sonat's common stock achieves certain specified levels.  At
December 31, 1993, 7,328 of the 29,400 cumulative restricted shares issued have
vested.  Stock-based employee compensation decreased Southern's pretax income
in 1993 by $5.1 million, decreased Southern's pretax income in 1992 by $1.8
million and increased Southern's pretax income in 1991 by $2.3 million.

                                       OF
                          SOUTHERN NATURAL GAS COMPANY


                 (ORIGINALLY INCORPORATED ON OCTOBER 30, 1935)

FIRST:The name of the corporation is SOUTHERN NATURAL GAS COMPANY.

SECOND:The address, including street, number, city, and county, of the
registered office of the Corporation in the State of Delaware is 32 Loockerman
Square, Suite L-100, City of Dover, County of Kent; and the name of the
registered agent of the Corporation in the State of Delaware at such address is
The Prentice-Hall Corporation System, Inc.

THIRD:The purpose of the Corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
Delaware.

FOURTH:The total number of shares which the Corporation shall have the
authority to issue is one thousand (1,000), all of which are to be Common Stock
of the par value of Three Dollars and Seventy-five Cents ($3.75) per share.

FIFTH:The following provisions are inserted for the management of the business
and for the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

(1)  The number of directors of the Corporation shall be such as from time to
time shall be fixed by, or in the manner provided in the By-Laws.  Election of
directors need not be by ballot unless the By-Laws so provide.

(2)  The Board of Directors shall have power without the assent or vote of the
stockholders

     (a)  To make, alter, amend, change, or repeal the By-Laws of the
Corporation other than By-Laws made by the stockholders which provide otherwise
for their alteration, amendment, change or repeal, but any By-Laws may be
altered, amended, changed or repealed by the stockholders at any annual meeting
or at any special meeting, provided that notice of such proposed alteration,
change or repeal is included in the notice of such meeting.

     (b)  To determine from time to time whether, and to what extent, and at
what times and places, and under what conditions and regulations, the accounts
and books of the Corporation (other than the stock ledger) or any of them,
shall be open to the inspection of the stockholders.

(3)  In addition to the powers and authorities hereinbefore or by statute
expressly conferred upon them, the directors are hereby empowered to exercise
all such powers and do all such acts and things as may be exercised or done by
the Corporation; subject, nevertheless, to the provisions of the statutes of
Delaware, of this certificate, and to any By-Laws from time to time made by the
stockholders; provided, however, that no By-Laws so made shall invalidate any
prior act of the directors which would have been valid if such By-Laws had not
been made.

(4)  At any special meeting of stockholders of the Corporation the notice of
which shall state that the removal of a director or directors and the filling
of a vacancy or vacancies are among the purposes of the
<PAGE>   2

meeting, the holders of the Common Stock by vote of a majority of the
outstanding shares thereof, may remove any director and, by vote of a majority
of the shares of Common Stock present in person or by proxy may fill any
vacancy caused by such removal.

(5) The annual meeting of stockholders of the Corporation shall be held each
year at such time as shall be specified in the By-Laws.  At such annual
meeting, or at such adjournment thereof as may be taken pursuant to the
By-Laws, the Board of Directors of the Corporation shall be elected to hold
office until the next succeeding annual meeting of stockholders and until the
election and qualification of their respective successors in office.

(6)  At each annual meeting of the stockholders, or at an adjournment thereof,
there shall be elected by plurality vote of the outstanding shares of Common
Stock an Auditor of the Corporation, who shall hold office until the next
annual meeting of stockholders. The Auditor shall be an individual who is a
member in good standing of the American Institute of Accountants or (if said
Institute shall cease to exist) of its successor or an organization of
comparable standing, or shall be a co-partnership a majority of whose members
are members in good standing of said Institute or its successor or comparable
organization as aforesaid; and shall in any event have rendered audit reports
for at least five corporations or associations each having at the time of such
reports assets carried on their respective balance sheets at more than
$20,000,000. The Auditor shall not be a director of the Corporation, nor an
officer or salaried employee thereof.  Not later than thirty days prior to the
day fixed for the annual meeting of stockholders in any year, the Auditor shall
submit a written report by the Auditor as to the balance sheet of the
Corporation as at the close of business on the December 31 next preceding the
date of such report, as to the surplus account of the Corporation and as to the
earnings or income of the Corporation since its organization or since the last
preceding report by the Auditor as the case may be. The Corporation shall cause
copies of such report to be mailed not later than twenty days prior to the day
fixed for such annual meeting to each stockholder of record of the Corporation.
The Board of Directors of the Corporation shall cause to be included in the
notice given to stockholders of each annual meeting a statement of the name of
the individual or co-partnership which the Board of Directors recommends for
election as Auditor at such meeting, and also a statement of the name of the
Auditor then in office; but no such recommendation by the Board of Directors
shall be binding upon the stockholders.  The Board of Directors shall cause a
copy of such notice to be mailed to the existing Auditor at the same time at
which it is mailed or otherwise given to stockholders.  No person, other than
the Auditor then in office, shall be eligible for election as Auditor at any
annual meeting of stockholders unless notice of intention to nominate that
person as Auditor has been given by a stockholder to the Corporation not less
than ten days before such annual meeting; the Corporation shall promptly mail a
copy of such notice to the Auditor then in office. The Auditor shall have the
right to attend all meetings of stockholders at which the Auditor or any
accounts of the Corporation examined or reported on by the Auditor are
considered, and to make any statement or explanation regarding the accounts
which the Auditor may desire; but the Auditor shall not be entitled to any
vote.  The Auditor shall have the right of access to all books, accounts,
vouchers and records of the Corporation and may require from its officers such
information and explanation as may be necessary for the performance of the
duties of the Auditor.  The officers and directors of the Corporation may rely
upon the accuracy of all reports by the Auditor to the Corporation or its
stockholders and will be protected in  any action or nonaction by them in good
faith in reliance thereon.  Semi-annual, quarterly or interim reports shall be
made by the Auditor from time to time as may be directed by the Board of
Directors of the Corporation.  The Board of Directors may fill any vacancy
occurring in the office of Auditor, by death, resignation or otherwise, at any
time except between the call and final adjournment of an annual meeting of
stockholders or of a special meeting of stockholders called for the purpose of
removing the Auditor or electing a new Auditor.  The Auditor may be removed,
and a new Auditor elected to fill the vacancy caused by such removal or
otherwise, at any special meeting of the stockholders the notice of which shall
include such removal and election as purposes of the meeting, by the vote of a
majority of 

                                    - 2 -
<PAGE>   3

the outstanding shares of the Common Stock of the Corporation; a copy of the
notice of any such meeting shall be mailed by the Corporation to the Auditor 
then in office at the same time at which such notice is mailed or otherwise 
given to stockholders.

(7)  In lieu of taking any permissive or requisite action by vote at any annual
or special meeting of stockholders, such action may be taken without a meeting,
without prior notice and without a vote, if a consent in writing, setting forth
the action so taken, shall be signed by all of the stockholders entitled to
vote upon such action at any such annual or special meeting.

(8)  The Board of Directors of the Corporation in its discretion may submit for
approval, ratification or confirmation by the stockholders any contract,
transaction or act of the Board of Directors or any committee thereof or of any
officer, agent or employee of the Corporation, and any such contract,
transaction or act which shall have been so approved, ratified or confirmed by
the holders of a majority of the issued and outstanding stock entitled to vote
shall be as valid and binding upon the Corporation and upon the stockholders
thereof as though it had been approved and ratified by each and every
stockholder of the Corporation.

(9)  No director shall be personally liable to the Corporation or any
stockholder for monetary damages for breach of fiduciary duty as a director,
except (i) for any breach of such director's duty of loyalty to the Corporation
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any
transaction from which the director derived an improper personal benefit.  If
the Delaware General Corporation Law is amended after approval by the
stockholders of this provision to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of directors of the Corporation shall be eliminated or limited to the full
extent permitted by the Delaware General Corporation Law, as so amended.

      The Corporation shall indemnify to the full extent permitted by the laws
of the State of Delaware as from time to time in effect, each person who is or
was a director or officer of the Corporation in the event that he was or is a
party or is threatened to be made a party to, or otherwise requires
representation by counsel in connection with, any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, by reason of the fact that he is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of
the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, or by
reason of any action alleged to have been taken or omitted in such capacity.
The right to indemnification conferred by this Section (9) shall also include
the right of such persons to be paid in advance by the Corporation for their
expenses to the full extent permitted by the laws of the State of Delaware as
from time to time in effect.  The right to indemnification conferred on the
directors and officers of the Corporation by this Section (9) shall be a
contract right.

      Unless otherwise determined by the Board of Directors of the Corporation,
the Corporation shall indemnify to the full extent permitted by the laws of the
State of Delaware as from time to time in effect, each person who is or was an
employee or agent of the Corporation in the event that he was or is a party or
is threatened to be made a party to, or otherwise requires representation by
counsel in connection with, any threatened, pending or completed action, suit
or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he is or was an employee or agent of the Corporation,
or is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, or by reason of any action alleged to have been taken or
omitted in such capacity.

      The rights and authority conferred in this Section (9) shall not be
exclusive of any other right which any person may have or hereafter acquire
under any statute, provision of this Certificate of Incorporation or the
By-Laws of the Corporation, agreement, vote of stockholders or disinterested
directors or otherwise.

      Neither the amendment nor repeal of this Section (9), nor the adoption of
any provision of the Certificate of Incorporation or By-Laws or of any statute
inconsistent with this Section (9), shall eliminate or reduce the effect of
this Section (9) in respect of any acts or omissions occurring prior to such
amendment, repeal or adoption of an inconsistent provision.

 SIXTH:Whenever a compromise or arrangement is proposed between the Corporation
and its creditors or any class of them and/or between the Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of the
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for the Corporation under the provisions of
Section 291 of Title 8 of the Delaware Code or on the application of trustees
in dissolution or of any receiver or receivers appointed for the Corporation
under the provisions of Section 279 of Title 8 of the Delaware Code, order a
meeting of the creditors or class of creditors, and/or of the stockholders or
class of stockholders of the Corporation, as the case may be, to be summoned in
such manner as the said Court directs.  If a majority in number representing
three-fourths in value of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of the Corporation, as the case may be,
agree to any compromise or arrangement and to any reorganization of the
Corporation as consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the Court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of the Corporation, as the case may be, and also on the
Corporation.

SEVENTH:The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this certificate of incorporation in the manner now
or hereafter prescribed by law, and all rights and powers conferred herein on
stockholders, directors and officers are subject to this reserved power.

This Restated Certificate of Incorporation only restates and integrates, and
does not further amend, the provisions of the Certificate of Incorporation of
this Corporation as theretofore amended or supplemented, there is no
discrepancy between those provisions and the provisions of this Restated
Certificate of Incorporation and there are no amendments herein having the
effect of reducing the capital of the Corporation.

votes are counted for such purpose, if (1) the material facts as to his
relationship or interest and as to the contract or transaction are disclosed or

thereof, or the shareholders.

officer, agent or employee of the Corporation, and any such contract,
transaction or act which shall have been so approved, ratified or confirmed by

thereof as though it had been approved and ratified by each and every
stockholder of the Corporation.

provided in the resolution or resolutions shall have and may exercise the
powers of the Board of Directors in the management of the business and affairs
of the Corporation, and may have power to authorize the seal of the Corporation

of a quorum.  Vacancies in such committees shall be filled by the Board of
Directors; provided, however, that in the absence or disqualification of any
member of such committee or committees, the member or members thereof present
at any meeting and not disqualified from voting, whether or not he or they
constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any such absent or disqualified
member.  The Board of Directors may at its pleasure discontinue any such
committee or committees.
