                           SONAT INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.       Basis of Presentation

         The accompanying  condensed  consolidated financial statements of Sonat
Inc. (Sonat) and its subsidiaries (the Company) have been prepared in accordance
with the  instructions  to Form 10-Q and include the  information  and footnotes
required by such  instructions.  In the opinion of management,  all adjustments,
including those of a normal recurring nature,  have been made that are necessary
for a fair presentation of the results for the interim periods presented herein.

         The 1997  periods  have  been  restated  for a change  to the full cost
method of accounting for the Company's oil and gas  operations  (see Note 2) and
to reflect the Company's merger with Zilkha Energy Company (see Note 3). Certain
other amounts in the 1997 condensed  consolidated financial statements and notes
have been reclassified to conform with the 1998 presentation.

         During the first quarter of 1998, the Company  recognized the effect of
a change in salvage values,  including reversal of excess depreciation  expense,
relating to certain fixed assets,  primarily aircraft and vehicles.  The change,
which was to comply with recent  Federal  Energy  Regulatory  Commission  (FERC)
directives,  increased net income for the nine-month  period ended September 30,
1998, by $4.6 million.  The effect of the change on the three-month period ended
September 30, 1998, was not material.

2.       Change in Method of Accounting For Oil and Gas Operations

         In September  1998, the Company  changed its accounting  method for oil
and gas operations as conducted by its subsidiaries,  Sonat Exploration  Company
and Sonat  Exploration  GOM (Sonat  Exploration),  from the  successful  efforts
method to the full cost  method  because  its future  capital  spending  will be
focused  significantly more on exploration  activity than in the past. Full cost
accounting,  which amortizes rather than expenses dry-hole exploration and other
related  costs,  provides a more  appropriate  method of matching  revenues  and
expenses  for the  Company's  exploration  strategy.  Exploration  activity  has
increased  from 6  percent  of 1995  capital  spending,  or $27  million,  to an
estimated 33 percent of 1998 capital spending,  or approximately $175 million. A
significant  percentage of Sonat  Exploration's 1999 capital program is expected
to be spent on exploratory drilling.

         The  adoption of the full cost method is expected to increase  1998 and
1999  normalized  earnings  from  levels  that  would have been  reported  under
successful  efforts  accounting  and,  more  importantly,  will reduce  earnings
volatility from quarter-to-quarter and year-to-year going forward. The Company's
earnings will now be more  comparable to its integrated  pipeline  company peers
that have substantial  exploration and production operations,  most of which use
the full cost method.

         Under the full cost method,  all  productive and  non-productive  costs
incurred in connection with the acquisition,  exploration and development of oil
and gas reserves are capitalized and amortized on the unit-of-production  method
using

proved  reserves.   Certain   unevaluated   properties  are  excluded  from  the
amortization  base until a  determination  has been made as to the  existence of
proved  reserves.  Since the  Company's  operations  are  limited  to the United
States, it utilizes a single cost center for amortization purposes.  Capitalized
costs are subject to a "ceiling  test" which limits such costs to the  aggregate
of the  present  value of  future  net  revenues  plus the lower of cost or fair
market value of unproved  properties.  Any conveyances of properties are treated
as  adjustments  to the  cost  of oil and  gas  properties  with no gain or loss
recognized.

         The Company has restated all prior financial  statements as a result of
the conversion to full cost accounting.  As a part of this process, all previous
charges related to the impairment of Sonat Exploration's assets, including those
taken in 1998, were reversed, which significantly raised the book value of those
properties as well as the Company's  stockholders' equity. The full cost method,
however,  requires  quarterly ceiling tests to ensure that the carrying value of
assets on the balance sheet is not overstated.  Sonat  Exploration has performed
ceiling tests for each of the three 1998 quarters.  At March 31, 1998,  June 30,
1998 and September 30, 1998, it was determined that  capitalized  costs exceeded
the ceiling test limits by $39.7  million,  $540.5  million and $455.0  million,
respectively,  which are  included  as ceiling  test  charges  in the  Condensed
Consolidated Statement of Operations.  The third quarter test was based on NYMEX
prices of $1.67 per  thousand  cubic feet (Mcf) for  natural  gas and $14.98 per
barrel for oil,  and was  adjusted  for hedges,  basis  differentials  and other
pricing  factors.  Future quarterly full cost ceiling tests will be based on the
then-current NYMEX prices for both natural gas and oil, after  adjustments.  The
end  result of the full  cost  conversion  is that both the book  value of Sonat
Exploration's  properties and the Company's  stockholders'  equity are at higher
levels  than  if  it  had  continued  with  the  successful  efforts  method  of
accounting.

         The effect of the accounting change on net income is as follows:

3.       Changes in Operations

         Business  Combination  - On  January  30,  1998,  following  a  special
shareholders'  meeting,  the Company  completed  the merger  with Zilkha  Energy
Company by exchanging  approximately  24.2 million  common shares for all of the
outstanding  shares  of Zilkha  Energy.  Zilkha  Energy  was a  privately  owned
exploration and production company.  Immediately thereafter Zilkha Energy's name
was changed to Sonat  Exploration GOM Inc. It operates mainly on the continental
shelf of the Gulf of Mexico.

         The merger constituted a tax-free reorganization and has been accounted
for as a pooling of interests under  Accounting  Principles  Board (APB) Opinion
No.  16.  Accordingly,   all  prior  period  condensed   consolidated  financial
statements,  notes and  operational  data have been  restated  to include  Sonat
Exploration GOM in the Company's financial statements for all periods reported.

         There were no  transactions  between  Sonat and Sonat  Exploration  GOM
prior to the combination.

         At December 31, 1997, Sonat  Exploration GOM had accrued $73.8 million,
which   represented   compensation  due  to  certain  employees  under  deferred
compensation  plans.  The liability was estimated based on the fair market value
of Sonat Exploration GOM as of December 31, 1997. The Company's  restricted cash
deposit at December 31, 1997,  reflected on the Condensed  Consolidated  Balance
Sheet was used to  settle  this  liability  and  certain  other  merger  related
expenses.

         Sonat  Exploration  Company  Restructuring  - On April  23,  1998,  the
Company   announced  a  restructuring   of  Sonat   Exploration   Company.   The
restructuring  included  significant  property  sales and certain cost reduction
activities  associated  with a  reduction  in work  force.  Oil and  natural gas
properties  with  a  net  book  value  of  approximately   $605  million  having
approximately  500 billion  cubic feet of natural gas  equivalent  reserves  and
daily net  production  of  approximately  190 million  cubic feet of natural gas
equivalent were sold or are in the process of being sold. Most of the sales have
been completed with proceeds used to pay down debt.

         A pretax  restructuring  charge  of  $15.0  million  for  restructuring
expenses  primarily  associated with a reduction in work force was recognized in
the second quarter of 1998. All work force reductions have been completed.

4.       Trading Activities and Derivative Financial Instruments

         The Company uses derivative  instruments  (commodity futures contracts,
options and price swap  agreements)  to both hedge its  commodity  price risk on
natural gas, crude oil and electricity, and as a market maker (trading activity)
in natural gas.



<PAGE>


4.       Trading Activities and Derivative Financial Instruments (Cont'd)

         Natural gas, crude oil and electricity  futures contracts are traded on
the New York Mercantile  Exchange  (NYMEX).  Natural gas contracts are for fixed
units of 10,000 MMBtu and are available for up to 36 months in the future. Crude
oil contracts are for fixed units of 1,000 barrels and are available for periods
up to 84 months in the future.  Electricity contracts are for 736 megawatt hours
and are available for up to 18 months in the future.

         Price swap  agreements  call for one party to make monthly  payments to
(or receive payments from) another party based upon the  differential  between a
fixed and a variable  price  (fixed-price  swap) or two variable  prices  (basis
swap) for a notional volume specified by the contract.

         Options can be exchange traded on the NYMEX or traded over the counter.
Exchange traded and  over-the-counter  options give the owner the right, but not
the obligation, to a futures contract, or to buy or sell an underlying commodity
at a given price, respectively.

         At September 30, 1998,  the Company had  outstanding  energy  commodity
futures,  swaps and options.  In the table below, buys of swaps represent either
1) payment of fixed price and receipt of NYMEX or index;  or 2) payment of NYMEX
or  index  and  receipt  of  index.  The  notional  volume  and  terms  of these
transactions are as follows:

Derivative Commodity Instruments Held or Issued for Trading Purposes

         The Company maintains active trading positions in natural gas and crude
oil commodity futures,  swap and option contracts and limits its risk to changes
in the  value of its  outstanding  positions  through  the use of  Value-at-Risk
models,   establishment  of  offsetting  positions,  and  limit  and  monitoring
procedures.  The  trading  operation  also enters  into  natural  gas  commodity
purchase and sale commitments.  These activities constitute its trading business
and are  essential  to provide  customers  with market  products at  competitive
prices.  All of these trading  positions are reported at fair value and recorded
under the heading of  Assets/Liabilities  from Trading  Activities  (current and
long-term)  in the Condensed  Consolidated  Balance  Sheets.  The change in fair
value is  recognized  in revenues as it occurs.  Fair value is subject to change
and reflects  management's  best estimate of market prices  considering  various
factors including closing exchange and over-the-counter  quotations,  time value
and  volatility  factors  underlying  the  commitments.  These market prices are
adjusted  to reflect  the  potential  impact of  liquidating  Sonat  Marketing's
position in an orderly  manner over a  reasonable  period of time under  present
market conditions.

     Net trading gains for the three months and nine months ended  September 30,

Derivative Commodity Instruments Held or Issued for Purposes Other Than Trading

         In  certain  cases  derivative  positions  are  taken  specifically  to
mitigate market price risk associated with significant physical transactions and
are accounted  for using hedge  accounting  provided they meet hedge  accounting
criteria. Under hedge accounting,  gains and losses from futures are deferred in
the  Condensed  Consolidated  Balance  Sheets in Deferred  Credits and Other and
recognized  in  earnings in  conjunction  with the  revenue  recognition  of the
underlying  physical  transaction.  Each net payment/receipt due or owed under a
swap  agreement  is  recognized  in  earnings  during  the  period  to which the
payment/receipt   relates,   and  there  is  no  recognition  in  the  Condensed
Consolidated  Balance  Sheets for  changes in the swap's  fair  value.  Gains or
losses  resulting  from  settlement of swaps are amortized  over their  original
terms.

         The derivative  instruments used to hedge commodity  transactions  have
historically  had high  correlation  with  commodity  prices and are expected to
continue to do so. In the event that correlation  falls below allowable  levels,
the gains or losses  associated  with the hedging  instruments  are  immediately
recognized to the extent that correlation is lost.

4.       Trading Activities and Derivative Financial Instruments (Cont'd)

         Sonat  Exploration  hedges a portion of its production by entering into
intercompany  swaps with Sonat  Marketing.  The  exposure  that Sonat  Marketing
assumes  from Sonat  Exploration  is then  hedged by  entering  into  derivative
instruments  with  outside  counterparties.  Sonat  Marketing  and  Sonat  Power
Marketing also hedge third-party  purchases and sales by entering into commodity
futures,  swaps and options.  The information in the following table  represents
the fair value of all outstanding derivative positions as of September 30, 1998.
Not included are the related physical positions that these derivative  positions
hedge.

         Deferred  amounts on open futures  positions  will mature over 1998 and
1999.

Credit Risk from Derivative Activities

         NYMEX  traded  futures  are  guaranteed  by the NYMEX and have  nominal
credit risk. On all other  transactions  described above, the Company is exposed
to credit risk in the event of nonperformance by the counterparties. The Company
has established policies and procedures to evaluate potential counterparties for
creditworthiness   before  entering  into   over-the-counter   swap  and  option
agreements.  The credit risk resulting from in-the-money swaps is monitored on a
regular basis  against  established  collateralization  limits and credit limits
establish by the Company. Due to changes in market conditions,  the market value
of swaps and options and the associated credit exposure with the  counterparties
can change  significantly.  At  September  30,  1998,  the  market  value of the
Company's   in-the-money   swaps  and   options  was  $7.6   million,   and  all
counterparties  were within collateral and credit limits except one counterparty
which was $0.3  million over their  credit  limit.  Reserves for credit risk are
established as necessary.

         In April 1997, units of Shell Oil Company and Amoco Corporation  joined
with   Southern    Natural   Gas   in   the    ownership   of   Destin,    a   1
billion-cubic-feet-per-day  pipeline  designed  to  transport  natural  gas from
deep-water  areas in the eastern  Gulf of Mexico.  Construction  of the pipeline
began in December 1997. Destin was partially  completed and placed in service in
September 1998, and is expected to be fully in service by January 1999. The FERC
has approved two  extensions  of Destin for a total filed cost of an  additional
$56  million.  The total  cost of Destin is now  estimated  to be $446  million.
Destin's  earnings in 1997 and 1998 primarily  relate to the allowance for funds
used during  construction  (AFUDC)  capitalized on its capital  expenditures  to
date.

6.       Debt and Lines of Credit

         Long-Term Debt and Lines of Credit - Sonat has a bank revolving  credit
agreement  that provides for periodic  borrowings and repayments of up to $500.0
million through June 30, 2001.  Borrowings are supported by unsecured promissory
notes  that,  at the option of the  Company,  will bear  interest  at the banks'
prevailing prime or  international  lending rate, or such rates as the banks may
competitively  bid. At December 31, 1997,  there was an  outstanding  balance of
$130.0 million. During the first nine months of 1998, $70.0 million was borrowed
and $200.0 million was repaid under the revolving credit agreement, resulting in
no amounts outstanding at September 30, 1998.

         In January 1998, Sonat made two public offerings of Notes pursuant to a
shelf registration  statement.  In one offering,  Sonat issued $100 million of 6
5/8 percent Notes due February 1, 2008, at 99.531 percent to yield 6.69 percent.
In the other offering, Sonat issued $100 million of 7 percent Notes due February
1, 2018,  at 99.787  percent to yield 7.02  percent.  The net proceeds  from the
offerings  were  used  for  general   corporate   purposes,   including  capital
expenditures, working capital and repayment of debt.

         In  September  1998,  Southern  Natural  Gas made a public  offering of
$100.0  million of its 6.125  percent  Notes due  September  15, 2008, at 99.531
percent to yield 6.189 percent. The net proceeds from the offering were used for
general corporate purposes, including capital expenditures.

         Unsecured Notes - Loans under all short-term  credit facilities are for
a duration of less than three months.

         In January 1998,  Sonat completed a new 364-day $700 million  revolving
credit  facility with 20 banks. In connection with this new facility the Company
terminated  existing  lines  of  credit  providing  for up to  $200  million  of
borrowings.  At September  30,  1998,  Sonat had  short-term  lines of credit of
$700.0 million  available  through  January 25, 1999.  Southern  Natural Gas had
short-term  lines of credit of $50.0  million  available  through May 31,  1999.
Borrowings  are  available for a period of not more than 364 days and are in the
form of  unsecured  promissory  notes that bear  interest  at rates based on the
banks'  prevailing  prime,  international  or  money-market  lending  rates.  At
September 30, 1998, Sonat had $25.5 million outstanding under its agreement at a
rate of 5.99 percent.  No amounts were  outstanding  under Southern Natural Gas'
agreement.

         Sonat had $611.8 million in commercial paper  outstanding at an average
rate of 5.82 percent at September 30, 1998.

7.       Rate Matters and Contingencies

         Periodically, Southern Natural Gas and its subsidiaries (Southern) make
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 provides reserves relating to such amounts collected subject to
refund, as appropriate, and makes refunds upon establishment of the final rates.
At September 30, 1998, Southern's rates are established by a settlement that was
approved  by FERC  orders  issued in 1995 and  1996.  All of its  customers  are
parties to the  settlement,  and all  revenue  is based on the final  settlement
rates and therefore is not being collected subject to refund.

8.       Comprehensive Income

     As  of  January  1,  1998,  the  Company  adopted  Statement  of  Financial
Accounting  Standards (SFAS) No. 130, Reporting  Comprehensive  Income. SFAS No.
130 establishes new rules for the reporting and display of comprehensive  income
and its components; however, the adoption of this Statement had no impact on the
Company's  net income  (loss) or  stockholders'  equity.  SFAS No. 130  requires
unrealized gains or losses on the Company's available-for-sale  securities to be
included in other  comprehensive  income.  Comprehensive  income (loss),  net of
related tax, is as follows:

9.       Segment Information

         As of January 1, 1998,  the Company  adopted SFAS No. 131,  Disclosures
about  Segments  of  an  Enterprise  and  Related  Information.   SFAS  No.  131
establishes  standards for the way public  enterprises are to report information
about  operating  segments  in annual  financial  statements  and  requires  the
reporting of selected  information about operating segments in interim financial
reports  issued to  stockholders.  SFAS No. 131 also  establishes  standards for
related  disclosures  about  products and services,  geographic  areas and major
customers.  The Company had  previously  modified its  definition of segments to
conform to the approach required by SFAS No. 131.

         The Company's  consolidated  financial statements reflect operations in
three segments:  Exploration and Production, Natural Gas Transmission and Energy
Services.

10.      Earnings Per Share

         The  calculation  of diluted  earnings  per share  differs from that of
basic  earnings  per share due to the  denominator  for the diluted  calculation
including common stock equivalents applicable to outstanding stock options.

         The  following  table  presents  the  computation  of basic and diluted
earnings (loss) per share of common stock:

EXPLORATION AND PRODUCTION

         The  Company  is engaged in the  exploration  for and the  acquisition,
development  and  production of oil and natural gas in the United States through
Sonat Exploration. Most of Sonat Exploration's natural gas production is sold to
Sonat  Marketing  Company  L.P.  (Sonat  Marketing),   the  Company's  affiliate
operating in the Energy Services segment.

         On January  30,  1998,  the  Company  completed  its merger with Zilkha
Energy  Company  for  $1.3  billion  (see  Note  3 of  the  Notes  to  Condensed
Consolidated Financial Statements).

         In September 1998, the Company changed its method of accounting for oil
and gas operations from successful efforts to full cost (see Note 2 of the Notes
to Condensed Consolidated Financial Statements).

         So far this year,  the  Company has been  successful  on four of the 13
exploratory  wells that it has  drilled in the Gulf of Mexico.  The  Company has
recently completed the technical and permitting work necessary to drill a number
of important offshore prospects, including its Timbalier Trench and Viosca Knoll
blocks.  With  these  prospects  now ready to drill and  because  of the  recent
decline  in day rates for  offshore  drilling  rigs and  related  services,  the
Company plans to increase  substantially its offshore  exploration activity with
13 wells  planned  for the  fourth  quarter  of 1998 and first  quarter of 1999.
Onshore  exploration  activity is also  expected to increase  sharply due to the
significant number of exploration  prospects that the Company has generated this
year.

         In the  August  Federal  Lease  Sale  171,  Sonat  Exploration  was the
successful bidder on 24 offshore tracts at a total cost of $6.9 million.  Twenty
of these  leases  are in deep water and are a part of the  Company's  efforts to
build a deep-water  exploration program in depth levels greater than 600 feet in
the Gulf of Mexico.

Third Quarter 1998 to Third Quarter 1997 Analysis

         EBIT decreased $23.9 million after excluding the recognition of ceiling
test charges of $455.0  million in the third  quarter of 1998 (see Note 2 of the
Notes to Condensed Consolidated  Financial  Statements),  primarily due to lower
revenues due to lower energy  prices and  production  volumes,  partly offset by
lower costs and expenses.

         Natural gas and oil and condensate  production decreased 21 percent and
7  percent,  respectively,  from the  third  quarter  of 1997  primarily  due to
property sales that have occurred as part of the previously  announced corporate
restructuring. Average realized natural gas prices decreased 11 percent to $1.85
per thousand  cubic feet (Mcf) from $2.08 per Mcf in the third  quarter of 1997.
Realized oil and condensate  prices decreased 34 percent to an average of $12.34
per  barrel  from  $18.72  per  barrel in the  third  quarter  of 1997.  Oil and
condensate production decreased 7 percent primarily due to property sales.
<PAGE>

         Costs and expenses were $33.4 million lower than the prior period after
excluding the ceiling test charges discussed  earlier.  Depreciation,  depletion
and amortization  expense  decreased by 21 percent due to lower production and a
slightly lower  amortization  rate ($1.06 for the 1998 period  compared to $1.07
for the 1997  period).  Taxes and other  expenses  decreased 69 percent due to a
contract  termination  fee incurred by Sonat  Exploration  GOM (formerly  Zilkha
Energy)  in  1997.  Operating  and  maintenance  expense  decreased  23  percent
primarily due to property sales in 1998.

         Other  income  increased  due to a gain on the  disposal of  marketable
securities in the 1998 period.

Nine Months 1998 to Nine Months 1997 Analysis

         EBIT  decreased  $64.4  million  after  excluding  the  recognition  of
$1,035.2  million for ceiling test  charges,  discussed  earlier,  and the $15.0
million  restructuring  charge recorded in the second quarter of 1998, primarily
due to lower energy prices and production volumes,  partly offset by lower costs
and expenses.

         Natural  gas  production  decreased  to 177 Bcf  from  196 Bcf in 1997.
Average  realized  natural gas prices  decreased 11 percent to $1.96 per Mcf for
the 1998  period  from  $2.20  per Mcf for the  1997  period.  Realized  oil and
condensate  prices  decreased 32 percent to an average of $13.44 per barrel from
$19.89 per barrel in the 1997 period. Oil and condensate production increased 20
percent, slightly offsetting these unfavorable factors.

         Costs and expenses were $42.3 million lower after excluding the charges
for  ceiling  tests  and   restructuring   in  the  1998  period.   General  and
administrative  expense  decreased 45 percent primarily as a result of executive
compensation  expense for Sonat  Exploration GOM, which was included in the 1997
period.  Operating and maintenance expense decreased 11 percent primarily due to
property sales during 1998. Taxes and other expenses decreased 22 percent due to
a contract termination fee incurred by Sonat Exploration GOM in the 1997 period.
Depreciation, depletion and amortization expense decreased slightly due to lower
volumes.

         Other income was slightly lower for the nine-month 1998 period compared
with the  nine-month  1997  period due to gains on the  disposal  of  marketable
securities in 1997, partly offset by a gain on disposal of marketable securities
in the 1998 period.

Hedging Activities

         Sonat Exploration,  through Sonat Marketing,  uses derivative financial
instruments  to manage  the  risks  associated  with  price  volatility  for its
production,  which it sells in the spot  market.  (See Market Risk and Note 4 of
the  Notes to  Condensed  Consolidated  Financial  Statements.)  Gains or losses
experienced on Sonat  Exploration's  hedging  transactions offset the changes in
revenue  recognized  on the sale of the  commodity.  Natural gas  revenues  were
reduced by $.2  million  and $5.9  million  in the  three-month  and  nine-month
periods  ended  September  30, 1998,  and were reduced by $2.1 million and $24.8
million in the  three-month  and  nine-month  periods ended  September 30, 1997,
respectively,  as a result of  hedging  activities.  There  were no oil  hedging
activities  reflected  in the 1998  period.  Hedging  activities  increased  oil
revenues by $.2 million in the three-month  period ended September 30, 1997, and
reduced oil revenues by $.5 million in the nine-month period ended September 30,
1997.

         A  portion  of Sonat  Exploration's  future  gas  production  is hedged
through the year 2012. At September  30, 1998,  Sonat  Exploration's  hedged gas
production is as follows:

NATURAL GAS TRANSMISSION

         The Company is engaged in the natural gas transmission business through
Southern Natural Gas Company and its subsidiaries (Southern) and Citrus Corp. (a
50   percent-owned   company).   Southern  and  Citrus  are  actively   pursuing
opportunities to expand their pipeline systems in their traditional market areas
and to connect new gas supplies.

         In April 1997, units of Shell Oil Company and Amoco Corporation  joined
with   Southern    Natural   Gas   in   the    ownership   of   Destin,    a   1
billion-cubic-feet-per-day  pipeline  designed  to  transport  natural  gas from
deep-water  areas in the  eastern  Gulf of Mexico.  Southern  Natural  Gas has a
one-third interest in this pipeline.  Shell and Amoco have made substantial firm
transportation  commitments  to this  pipeline.  Eight other  shippers have also
dedicated their  production from certain leases in the eastern Gulf of Mexico to
Destin for  transportation  and discussions are under way with other prospective
shippers.  Construction  of the  pipeline  began in  December  1997,  and it was
partially  completed  and in service in  September  1998,  and is expected to be
fully in service by January  1999.  In June  1998,  the FERC  approved  Destin's
application to extend its pipeline  system  approximately  14 miles to transport
additional gas reserves committed to Destin's system. This extension is expected
to be in  service  in late  1998.  In July 1998 the FERC also  approved  another
Destin application to extend its pipeline by approximately 31 miles to transport
additional gas reserves  committed to its system.  This extension is expected to
be in  service  in early  1999.  The  total  capital  expended  by Destin is now
estimated to be $446 million.

         Southern  Natural Gas is moving forward on three expansions to northern
Alabama,  eastern Tennessee, and central Alabama that have a total filed capital
cost of $126 million.  The North Alabama  expansion,  which originally  received
FERC  approval in May 1997, is now  anticipated  to go in service in the fall of
1999.  Southern  Natural  Gas  received  FERC  approval  in  October  1998 of an
application  that it had filed to change the route of the pipeline as it crosses
the Wheeler National  Wildlife Refuge,  but the new route must still be approved
by the U.S. Fish and Wildlife  Service.  The 122-mile  expansion will provide 76
million-cubic-feet-per-day  capacity to the  participating  customers.  A second
expansion  to serve  customers  primarily  in eastern  Tennessee  received  FERC
approval  in April 1998 and was placed in service  in  November  1998.  Southern
Natural Gas has firm transportation  commitments  totaling 65 million cubic feet
of natural gas per day from customers in eastern Tennessee,  Georgia and Alabama
related to this  expansion.  The  expansion  in central  Alabama  received  FERC
approval  in March 1998 and is also  expected  to go in service in  November  of
1998.  This  expansion  will  provide  34  million  cubic  feet  per day of firm
transportation to Alabama Power Company and two other customers.

         In December  1997,  an  affiliate of AGL  Resources,  Inc. and Southern
Natural Gas formed a new entity,  Etowah LNG Company,  L.L.C.  (Etowah  LNG), to
jointly construct,  own and operate a new liquefied natural gas peaking facility
in Polk County,  Georgia.  Peaking services provide supplemental gas supplies on
days when demand is highest,  typically during the winter.  Under the agreement,
AGL Resources  and Southern  Natural Gas each will own 50 percent of Etowah LNG,
which will be regulated by the FERC.  The proposed  plant will connect  directly
into AGL Resources' principal natural gas distribution  subsidiary,  Atlanta Gas
Light  Company,  and  Southern  Natural Gas'  pipeline.  Etowah LNG will provide
natural gas  storage  and peaking  services to Atlanta Gas Light and the city of
Austell,  Georgia. The new facility will cost approximately $90 million with 300
million  cubic  feet per day of  deliverability  capacity.  Etowah  LNG  filed a
certificate application with the FERC in April 1998. Subject to receiving timely
FERC approval, construction will begin in early 1999 in order to provide peaking
services during the 2001-02 winter heating season.  The agreement for Etowah LNG
to provide services to Atlanta Gas Light includes, however, a provision allowing
Atlanta Gas Light to terminate  the  agreement in the event it does not receive,
with respect to the  agreement,  a  satisfactory  order from the Georgia  Public
Service  Commission  (Georgia  PSC). In September 1998 the Georgia PSC issued an
order approving the agreement, but allowed for further review of it. In light of
this order,  the parties  have  agreed to extend the time  period  during  which
Atlanta Gas Light may  terminate  the agreement to December 15, 1998. If Atlanta
Gas Light  exercises its option to terminate its service  agreement  with Etowah
LNG,  the project  would not go forward and Atlanta Gas Light would be obligated
to reimburse Etowah LNG for all of its costs incurred in the project to date.

Third Quarter 1998 to Third Quarter 1997 Analysis

         Southern  Natural Gas Company and  Subsidiaries - EBIT for Southern was
$46.5  million in the third  quarter of 1998  compared with $43.6 million in the
third  quarter of 1997.  The  increase  was  primarily  due to higher  equity in
earnings  of Destin and an  expansion  placed in  service,  partially  offset by
higher depreciation expense.

         Market  transportation  revenues  increased  as a result of the  recent
expansion. Supply transportation revenues decreased due to a decrease in volumes
as a result of hurricanes and tropical storms, and natural  production  declines
taking  place in  certain  Gulf of Mexico  fields.  General  and  administrative
expense  decreased   primarily  due  to  lower  employee  benefit  expenses  and
stock-based   compensation   expense.   Depreciation  and  amortization  expense
increased in the 1998 period due to plant  additions and pursuant to a provision
of the customer  settlement allowing a deferral of depreciation on certain plant
categories until March 1, 1998. That deferral is now being amortized.

         Equity in earnings of unconsolidated  affiliates  increased in 1998 due
to earnings of Destin,  primarily  resulting from AFUDC capitalized.  During the
third quarter,  construction of the offshore  portion of the Destin pipeline was
completed,  and it is currently  transporting about 90 million cubic feet (MMcf)
of natural gas per day. As additional  reserves are connected  during the fourth
quarter, daily throughput is expected to exceed 200 MMcf per day by year end.

         Citrus - Equity in earnings of Citrus  increased  $1.1  million to $6.7
million for the three months ended September 30, 1998. The increase is primarily
due to the  recognition  of credits on a gas supply  agreement,  lower  interest
expense and an  adjustment  to a reserve for gas  imbalances,  partly  offset by
higher operating expenses.

Nine Months 1998 to Nine Months 1997 Analysis

         Southern Natural Gas Company and Subsidiaries - EBIT was $163.4 million
for the nine months ending September 30, 1998,  compared with $146.0 million for
the same 1997 period.  The increase was primarily due to an expansion  placed in
service,  lower expenses and increased earnings of Destin.  Partially offsetting
these increases was the net effect of reserve  adjustments  made in the 1997 and
1998 periods, which is discussed below.

         Market  transportation  revenues  improved  primarily  due to a  recent
expansion.  Other  revenues  decreased  due to a favorable  $10 million  reserve
adjustment in 1997 relating to  Southern's  obligation to pay royalty  claims in
connection  with  take-or-pay  settlements  entered  into in the 1980's,  offset
partially by the reversal of the remaining  $4.2 million of royalty  reserves in
1998. Such reversal was made because  management  determined that the likelihood
of the Company making any significant  royalty payments as a result of its prior
take-or-pay   settlements  was  remote.  General  and  administrative   expenses
decreased  primarily due to lower employee  benefit  expenses,  lower  insurance
expenses  and  lower   stock-based   compensation   expense.   Depreciation  and
amortization  expense  decreased  primarily  due to an adjustment of the salvage
value on certain fixed assets (see Note 1 of the Notes to Condensed Consolidated
Financial Statements).  Increases due to plant additions and the amortization of
the deferred  depreciation  pursuant to the customer settlement partially offset
this decrease.
<PAGE>

         Equity in earnings of unconsolidated  affiliates  increased in 1998 due
to earnings of Destin, primarily resulting from AFUDC capitalized on its current
construction costs. Other income was lower primarily due to the recognition of a
gain on the termination of a forward rate agreement in the 1997 period.

         Citrus - Equity in earnings of Citrus  increased  $4.0 million to $22.4
million for the nine months ended  September 30, 1998. The increase is primarily
due to the  recognition of credits on a gas supply  agreement,  lower  operating
expenses and lower  interest  expense,  partly offset by reduced  utilization of
firm  transportation  capacity  held by Citrus  Trading  and lower  revenues  at
Florida Gas due to lower throughput.

Natural Gas Sales and Supply

         As a result of FERC Order No. 636,  Southern  Natural Gas terminated or
renegotiated  to market pricing  substantially  all of its gas supply  contracts
through which it had historically obtained its long-term gas supply. Pending the
termination of the remaining supply  contracts,  Southern Natural Gas' remaining
gas supply is sold on a month-to-month  basis. Gas sales revenue and natural gas
cost are included in other revenue.

         Southern Natural Gas' annual purchase  commitments  total less than $25
million per year for 1998 and subsequent  years.  Based on Southern Natural Gas'
current  expectations  with  respect to natural gas prices in 1998 and the years
following,  only an  insignificant  amount of gas  volumes is  expected to be at
prices above market.

Rate Matters

         Under  terms of a  settlement  approved  by the FERC,  all of  Southern
Natural Gas' previously  pending rate proceedings and proceedings to recover gas
supply realignment and other transition costs associated with the implementation
of FERC Order No.  636 have been  resolved.  The  settlement  requires  Southern
Natural Gas to file a new rate case no later than September 1, 1999.

         In September  1997,  the FERC approved a Rate Case  Settlement  between
Florida Gas and its customers.  The terms of the  settlement  provide for tiered
rates effective  beginning March 1, 1997, which, for a two-year period,  reflect
an increase over the rates in effect prior to the rate filing for transportation
through both the pre expansion and Phase III expansion  systems.  The settlement
resolved all issues related to Phase III construction and the construction  cost
audit. The settlement terms require Florida Gas to file a new rate case no later
than October 1, 2001.

         In 1998 a  subsidiary  of Sonat Energy  Services  acquired a 50 percent
interest in a natural  gas-fired power plant in Georgia (the  Mid-Georgia  Cogen
plant) for a gross  investment  of  approximately  $28 million.  The power plant
began operations in June 1998. In July 1998, Sonat Energy Services announced its
intention to develop a 680-megawatt  natural  gas-fired peaking power plant near
Columbus,  Georgia.  The Cataula Power Plant, which will have a gross investment
of approximately  $227 million,  is scheduled to begin  commercial  operation in
June 2000.  The plant  will  provide  energy to serve the  growing  Georgia  and
Southeast power markets during peak power demand periods.  Sonat Energy Services
is pursuing additional power plant opportunities.

         Sonat Intrastate-Alabama Inc. (SIA), a wholly owned subsidiary of Sonat
Energy  Services,  owns an  approximately  450-mile  intrastate  pipeline system
extending  from  natural  gas fields and coal seam gas  production  areas in the
Black  Warrior  Basin in  northwest  and  central  Alabama to  connections  with
customers in Alabama,  as well as  interconnections  with three other pipelines,
including Southern. SIA's throughput in the first nine months of 1998 was 31 Bcf
compared with 26 Bcf in the first nine months of 1997.

         Sonat Power Systems Inc., a wholly owned subsidiary of Sonat,  formed a
strategic alliance in 1997 with AlliedSignal Power Systems Inc., an unaffiliated
company,  to market and support its onsite electric power systems in 13 Southern
states from Texas to Virginia, and the District of Columbia.

Third Quarter 1998 to Third Quarter 1997 Analysis

         Third quarter 1998 financial  results  improved from third quarter 1997
levels,  as EBIT rose to $4.2 million from $.7 million in 1997. The increase was
due  to  better  power  marketing   results  and  the  contribution  of  the  50
percent-owned  Mid-Georgia  Cogen L.P. power plant.  Sonat  Marketing  Company's
third quarter  physical sales volumes were slightly below 1997 levels.  Notional
sales  volumes  from  natural gas  derivative  transactions  more than  doubled,
however,  reflecting an increase in Sonat Marketing's financial  transactions on
behalf of  customers  and an increase in reliance on financial  transactions  to
manage its basis  positions.  While Sonat Power  Marketing's  third quarter 1998
volumes were slightly below 1997 levels,  margins were substantially  better due
to improved market  conditions.  Sonat Power Marketing's  financial results also
benefited from marketing  arrangements,  whereby it  participates  in the spread
between natural gas and electricity prices.

Nine Months 1998 to Nine Months 1997 Analysis

         EBIT for the first nine  months of 1998 rose to $6.7  million  compared
with $1.5  million  for the first  nine  months of 1997.  The  improved  results
reflect  higher  volumes  at Sonat  Power  Marketing,  better  margins,  and the
contribution  of  the  Mid-Georgia  Cogen  L.P.  power  plant.   Although  Sonat
Marketing's physical sales volumes were essentially flat, notional sales volumes
more than doubled.  Sonat Power  Marketing's  sales volumes  reached 9.0 million
megawatt hours, up  significantly  from 6.7 million  megawatt hours in the first
nine months of 1997. The initiation of commercial  operations at the Mid-Georgia
plant in June 1998 and electric  power  marketing  opportunities  created by the
above  normal  temperatures  in the  Southeast  and Midwest  contributed  to the
increase  in EBIT.  Results  for 1998  reflect  start-up  losses for Sonat Power
Systems, which slightly offset these favorable factors.

</TABLE>

         Net interest  expense  increased in both the three-month and nine-month
periods of 1998 as  compared to the same  periods of 1997 due to higher  average
debt levels. Partially offsetting was the effect of lower interest rates on debt
in both periods of 1998.  In addition,  the  nine-month  period of 1998 reflects
higher  interest  income  on  restricted  cash and other  investments.  Interest
capitalized  decreased in both periods of 1998 due to lower interest capitalized
at Sonat Exploration.

</TABLE>

         Income tax expense  decreased  in both  periods due to the ceiling test
charges related to the Company's oil and gas  operations.  Absent these charges,
the  effective  tax rate was lower in both  periods of 1998 as  compared to 1997
because tax preference  items had a greater impact on income before income taxes
in the 1998 periods.

</TABLE>

         Cash flow from operations decreased $129.9 million compared to the 1997
period primarily due to lower operating results at Sonat Exploration.  Partially
offsetting the decrease was higher cash flows at Sonat Energy Services.
Operating results were discussed earlier.

         Depreciation,  depletion,  and  amortization  and deferred income taxes
include  a  charge  of  $1,035.2  million  and  a  benefit  of  $362.3  million,
respectively,  for ceiling test charges related to Sonat  Exploration's  oil and
gas properties in 1998. Absent the ceiling test charges,  the change in deferred
income  taxes and accrued  interest  and income  taxes  primarily  reflects  the
capitalization of intangible drilling costs in the current period. The change in
accounts  receivable  and accounts  payable is primarily  attributable  to lower
natural gas prices and volumes. The change in restricted cash, accrued long-term
compensation,  and other current assets and liabilities  primarily represent the
payment of certain  expenses in connection  with the merger  between the Company
and  Zilkha  Energy  in  January  1998  (see  Note 3 of the  Notes to  Condensed
Consolidated Financial Statements).  Lower broker deposits at Sonat Marketing in
the  current  period   slightly   offset  the  decline  in  current  assets  and
liabilities.

     The caption  Other in the 1997 period  includes  $15.4  million of deferred
gains on derivatives designated as hedges at Sonat Marketing.

</TABLE>

         Net cash used in investing  activities was $271.5 million lower in 1998
compared to 1997. The decrease was primarily  attributable  to proceeds from the
sale of certain  oil and gas  properties  (see Note 3 of the Notes to  Condensed
Consolidated  Financial  Statements).  The sale of those properties also had the
effect of decreasing  capital  expenditures at Sonat  Exploration in the current
period.  Higher  investments in  unconsolidated  affiliates,  specifically,  the
Destin  and  the  Mid-Georgia  Cogen  joint  ventures   partially  offset  these
decreases.

     The  Company's  share  of  capital   expenditures  by  its   unconsolidated

and 1997, respectively.

</TABLE>

         Net cash provided by financing  activities  was $229.8 million lower in
1998  period  compared  to  1997.  The  proceeds  from  the  sale of oil and gas
properties were used to repay  borrowings under Sonat's floating rate facilities
in the current period.

CAPITAL RESOURCES

         At  September  30,  1998,  the  Company  had bank lines of credit and a
revolving  credit  agreement  with banks with a total capacity of $1.25 billion.
The  Company's  bank and  commercial  paper  borrowings in the aggregate are not
authorized to exceed the maximum amount  available under its lines of credit and
revolving  credit  agreement.  As a result,  after  giving  effect to the $611.8
million of commercial  paper and $25.5 million of borrowings from the short-term
lines of credit, $612.7 million was available to the Company under such lines of
credit and revolving credit agreement at September 30, 1998.

         Sonat and Southern Natural Gas have shelf registration  statements with
the Securities and Exchange  Commission  which provide for the issuance of up to
$500 million in debt securities by both companies.  Southern  Natural Gas issued
$100 million in debt under its  registration  statement in the third  quarter of
1998.

         The Company's capital expenditures and other investing requirements for
1998 are expected to aggregate $910.2 million.  This amount reflects investments
in unconsolidated  affiliates and proposed expenditures for oil and gas property
acquisitions,   exploration  and  development,   pipeline  expansion  and  other
projects.  The Company  completed  the Zilkha Energy merger on January 30, 1998,
issuing  $1.04 billion of common stock to the Zilkha  Energy  shareholders  (see
Note 3 of  the  Notes  to  Condensed  Consolidated  Financial  Statements).  The
Company's  cash  requirements  relating  to the  Zilkha  Energy  merger  totaled
approximately $290 million,  principally for repayment of debt and certain other
liabilities of Zilkha Energy and transaction expenses.
<PAGE>

         The Company has a stock repurchase program in effect through the end of
1998. As of September 30, 1998, the Company had remaining  authority to purchase
approximately  967,000 shares of the Company's  common stock.  Shares  purchased
under the program are expected to be reissued in connection  with employee stock
option and restricted stock programs.

         The Company  believes that cash flow from  operations and borrowings in
either the private or public  market will  provide the Company with the means to
fund operations and currently planned investment and capital expenditures.

MARKET RISK

         Financial  instruments of the Company expose it to both commodity price
risk and interest rate risk.

         Commodity  Price Risk - The Company's  primary  market risk exposure is
the volatility of energy commodity prices, relating to the portfolio position of
its  financial  instruments  and  physical  commitments,  which can  affect  the
operating  results of Sonat  Exploration and Sonat Energy Services.  The Company
uses commodity futures contracts, options and price swap agreements to hedge its
commodity  price risk on crude oil,  natural gas and  electricity.  Sonat Energy
Services performs all hedging activity (non-trading) for both its own operations
and for the operations of Sonat Exploration.  Sonat Energy Services, through its
subsidiary,  Sonat Marketing, also uses derivative instruments as a market maker
(trading  activity)  by  maintaining  active  trading  positions  in natural gas
futures and swap  contracts and limiting its risk to changes in the value of its
outstanding positions through the use of Value-at-Risk models,  establishment of
offsetting positions, and limit and monitoring procedures.

         The  Company's   non-trading   (hedging)  and  trading  activities  are
implemented  under a set of  policies  approved  by the Board of  Directors.  In
addition,  all derivative activities are internally reviewed by a Risk Oversight
Committee  to  ensure  compliance  with  all  policies.  The  Company's  use  of
derivative instruments to reduce the effect of market volatility is described in
Note 4 of the Notes to Condensed  Consolidated  Financial  Statements.  The Risk
Oversight Committee and management monitor the portfolio Value-at-Risk to ensure
compliance with Board limits.

         Interest  Rate Risk - The Company's  entire  portfolio of interest rate
risk instruments is classified as non-trading. The Company's interest income and
expense are  sensitive to changes in the level of short-term  interest  rates in
the  United  States.  In  general,  the  Company  uses  excess  funds to  reduce
short-term debt levels and therefore has minimal cash equivalent investments. To
mitigate the impact of fluctuations in interest rates,  the Company  maintains a
balance among components of its capital structure, providing a mix of maturities
and pricing methods for its debt  obligations.  In the past the Company has used
derivative  instruments to aid in its management of interest rate risk, although
it is not currently doing so.

YEAR 2000 PROJECT

         The Company is aware of the  potential  impact the Year 2000 could have
on its information  technology and business  infrastructure.  To answer the Year
2000  challenge,  the Sonat Board of Directors  directed  that a  corporate-wide
initiative  be  undertaken.  A  consulting  firm was  engaged  to assist in this
effort.

         The  Company  has  divided  its  Year  2000  project  into  assessment,
implementation,  and testing phases.  During the assessment  phase,  the Company
completed a comprehensive inventory of IT systems, embedded systems,  equipment,
computer  hardware and software  that rely on a computer chip as well as service
providers that could be impacted by the Year 2000 problem.  For vendor  supplied
items,  the Company has contacted its vendors  seeking  written  verification of
Year 2000 readiness.  In addition,  the Company is also  communicating  with its
customers and business  partners to determine the extent to which the Company is
vulnerable  to the failure of those third  parties to remediate  their Year 2000
issue.

         The  Company is  currently  engaged in the  implementation  and testing
phases of the Year 2000 project.  The implementation  phase includes  completing
the replacement of mainframe systems with Year 2000-compliant vendor packages on
new  client/server  platforms  and  performing  any required  modifications  and
upgrades  identified  during the  assessment  phase.  The testing phase involves
testing  systems for Year 2000  readiness.  The Company is scheduled to have all
critical  systems  tested,  remediations  plans defined,  and corrective  action
underway by December  31,  1998.  All  remediation  efforts are  scheduled to be
completed by June 30, 1999.

         The  Company  is  also  currently   developing   contingency  plans  as
practicable for critical  systems,  service  providers,  and business  partners.
These plans involve  developing  contingencies for failures that may result from
the Year 2000 problem. The Company is scheduled to have these plans completed by
June 30, 1999. The Company has not completed  analyzing worst case scenarios and
therefore is not able to estimate potential lost revenue at this time.

         The estimated  cost to the Company of the Year 2000 project for capital
as well as general and administrative  costs is expected to be $5 million to $10
million.  As of September 30, 1998, the Company has incurred  approximately $1.3
million  in Year 2000  project  costs.  The  Company  expects  to fund Year 2000
expenditures from normal operations.

RECENT ACCOUNTING PRONOUNCEMENT

         In June 1998, the Financial  Accounting  Standards  Board (FASB) issued
Statement of  Financial  Accounting  Standards  (SFAS) No. 133,  Accounting  for
Derivative Instruments and Hedging Activities. SFAS No. 133 requires the Company
to recognize all  derivatives  on the balance  sheet at fair value.  Derivatives
that are not hedges  must be adjusted  to fair value  through  income as changes
occur.  If the  derivative  is a hedge,  depending  on the  nature of the hedge,
changes in the fair value of derivatives are either offset against the change in
fair value of assets,  liabilities,  or firm  commitments  through  earnings  or
recognized in other comprehensive  income until the hedged item is recognized in
earnings. The ineffective portion of a derivative's change in fair value will be
immediately  recognized in earnings.  SFAS No. 133 becomes  effective for fiscal
years beginning after June 15, 1999. As a result,  calendar  year-end  companies
have until January 1, 2000, to adopt. Early application is encouraged,  but only
permitted as of the beginning of any fiscal quarter.  Retroactive application to
previous  periods,  even previous  quarters  within the same fiscal year, is not
permitted.  The Company has not yet  determined  what the effect of SFAS No. 133
will be on the earnings and financial position of the Company.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

         This  Quarterly  Report  contains  certain  forward-looking  statements
regarding  the  Company's  business  plans  and  prospects,  objectives,  future
drilling plans,  expansion projects,  proposed capital expenditures and expected
performance  or  results.   These   forward-looking   statements  are  based  on
assumptions that the Company believes are reasonable,  but are subject to a wide
range of risks and uncertainties and, as a result, actual results and experience
may  differ  materially  from the  anticipated  results  or  other  expectations
expressed  in such  forward-looking  statements.  Such  statements  are  made in
reliance on the safe harbor  provisions  of the  Private  Securities  Litigation
Reform Act of 1995.

         Important  factors  that could cause actual  results to differ  include
changes  in oil and  gas  prices  and  underlying  demand,  which  would  affect
profitability  and might  cause the  Company to alter its plans;  the timing and
success of the Company's  exploration and development  drilling programs,  which
would  affect  production  levels and  reserves;  the  results of the  Company's
hedging activities;  risks incident to the drilling and operation of oil and gas
wells; future drilling, production and development costs, including drilling rig
rates;  the  success  of  the  Company's  cost  reduction  activities;  and  the
requirements to receive various governmental approvals to proceed with pipeline,
storage and power generation projects, and unanticipated  construction delays in
connection  with such  projects.  Realization  of the Company's  objectives  and
expected  performance can also be adversely affected by the actions of customers
and competitors, changes in governmental regulation of the Company's businesses,
and changes in general  economic  conditions  and the state of domestic  capital
markets.

         Changes in business conditions in the oil and gas industry and at Sonat
Exploration  could  change its  current  plans for  increasing  its  onshore and
offshore  exploration  programs.  Such changes would include material changes in
oil and gas prices and  drilling rig rates.  Finally,  there can be no assurance
that  Destin will be able to timely  connect  new fields or that the  production
from those fields will allow it to meet its planned throughput objectives.

                              EXECUTIVE AWARD PLAN
                                       OF
                                   SONAT INC.
                  (As Amended and Restated as of July 23, 1998)


                                   I. GENERAL

1.1      Purpose of the Plan

         The Executive  Award Plan (the "Plan") of Sonat Inc. (the "Company") is
intended to advance the best  interests of the Company and its  subsidiaries  by
providing key employees with additional  incentives through the grant of options
("Options") to purchase shares of Common Stock of the Company  ("Common  Stock")
and through the award of shares of restricted Common Stock ("Restricted Stock"),
thereby increasing the personal stake of such employees in the continued success
and growth of the  Company and  encouraging  them to remain in the employ of the
Company.

         The Plan was adopted  effective  May 1, 1981,  and has been  amended at
various times. The provisions of the Plan as hereby amended and restated may, at
the  discretion of the  Committee  referred to below,  be made  available to all
grants outstanding on the effective date of this Amendment and Restatement,  and
all awards granted after such date,  except that no such  provision  shall alter
any outstanding grant in a manner  unfavorable to the holder thereof without the
written consent of the holder.

1.2      Administration of the Plan

         (a) The  Plan  shall  be  administered  by the  Executive  Compensation
Committee  or other  designated  committee  (the  "Committee")  of the  Board of
Directors of the Company (the "Board of  Directors")  which shall  consist of at
least three  Directors all of whom are not eligible to  participate  in the Plan
and are  "disinterested"  within the meaning of Rule 16b-3 under the  Securities
Exchange Act of 1934 (the "Exchange Act"). The Committee shall have authority to
interpret  conclusively  the  provisions  of the Plan,  to adopt  such rules and
regulations  for  carrying  out the Plan as it may  deem  advisable,  to  decide
conclusively  all questions of fact arising in the  application of the Plan, and
to make all other  determinations  necessary or advisable for the administration
of the Plan. All decisions and acts of the Committee  shall be final and binding
upon all affected Plan participants.

         (b) The  Committee  shall  meet  once  each  fiscal  year,  and at such
additional  times as it may  determine or at the request of the chief  executive
officer of the Company,  to  designate  the  eligible  employees,  if any, to be
granted  awards  under the Plan and the type and  amount of such  awards and the
time when awards will be granted.  All awards granted under the Plan shall be on
the terms and subject to the conditions hereinafter provided.

1.3      Eligible Participants

         Key employees, including officers, of the Company and its subsidiaries,
and of partnerships or joint ventures in which the Company and its  subsidiaries
have a significant  ownership  interest as  determined by the Committee  (all of
such  subsidiaries,  partnerships  and  joint  ventures  being  referred  to  as
"Subsidiaries")  shall be eligible to participate in the Plan. Directors who are
not  employees  of the  Company or its  Subsidiaries  shall not be  eligible  to
participate in the Plan.

1.4      Awards Under the Plan

         Awards  under the Plan may be in the form of (i)  Options  to  purchase
shares of Common  Stock,  (ii)  Stock  Appreciation  Rights  and  Limited  Stock
Appreciation  Rights  which may be issued in  tandem  with such  Options,  (iii)
shares of Restricted Stock, and (iv) Supplemental  Payments which may be awarded
with respect to Options,  Stock Appreciation Rights,  Limited Stock Appreciation
Rights, and Restricted Stock, or (v) any combination of the foregoing.

1.5      Shares Subject to the Plan

         The aggregate number of shares of Common Stock which may be issued with
respect to Options or Restricted  Stock granted after April 27, 1995  (including
Stock Appreciation  Rights,  Limited Stock Appreciation  Rights and Supplemental
Payments  related  thereto) shall not exceed (i) 4,000,000  shares plus (ii) the
number of shares  previously  authorized for use in the Plan which have not been
issued or have again  become  available  for grants  pursuant  to the  following
paragraph.  At no time  shall the  number of shares  issued  plus the  number of
shares subject to outstanding  awards under the Plan exceed the number of shares
that may be issued  under the Plan.  Options  with  respect to more than 250,000
shares of Common  Stock  shall not be granted to any  optionee  in any  12-month
period.  Shares  distributed  pursuant to the Plan may consist of authorized but
unissued shares or treasury  shares of the Company,  as shall be determined from
time to time by the Board of Directors.

         If any Option  under the Plan shall  expire,  terminate  or be canceled
(except  upon the holder's  exercise of a related  Stock  Appreciation  Right or
Limited Stock  Appreciation  Right) for any reason without having been exercised
in full, or if any shares of Restricted Stock shall be forfeited to the Company,
the unexercised Options and forfeited shares of Restricted Stock shall not count
against the above limit and shall again  become  available  for grants under the
Plan  (regardless  of  whether  the holder of such  Options  or shares  received
dividends or other  economic  benefits  with respect to such Options or shares).
Shares of Common Stock equal in number to the shares  surrendered  in payment of
the option  price,  and shares of Common  Stock  which are  withheld in order to
satisfy federal, state or local tax liability, shall not count against the above
limit  and  shall   again   become   available   for  grants   under  the  Plan.
Notwithstanding  the  foregoing,  any shares which were  authorized for issuance
under  the Plan as in  effect  on April 25,  1985  shall  not be  available  for
issuance with respect to awards granted after April 24, 1995.

1.6      Other Compensation Programs

         The  existence  and terms of the Plan shall not limit the  authority of
the  Board  of  Directors  in  compensating  employees  of the  Company  and its
subsidiaries in such other forms and amounts, including compensation pursuant to
any other plans as may be  currently  in effect or adopted in the future,  as it
may determine from time to time.


                                II. STOCK OPTIONS

2.1      Terms and Conditions of Options

         Subject to the following provisions, all Options granted under the Plan
shall be in such form and shall have such terms and conditions as the Committee,
in its discretion, may from time to time determine.

                  (a) Option Price. The option price per share shall not be less
         than the fair market  value of the Common Stock (as  determined  by the
         Committee) on the date the Option is granted.

                  (b) Term of Option. The term of an Option shall not exceed ten
         years from the date of grant, and,  notwithstanding any other provision
         of this Plan, no Option shall be exercised  after the expiration of its
         term.

                  (c) Exercise of Options.  Options shall be exercisable at such
         time or times and subject to such terms and conditions as the Committee
         shall specify in the Option grant.  The Committee shall have discretion
         to at any time  declare all or any  portion of the Options  held by any
         optionee to be immediately  exercisable.  An Option may be exercised in
         accordance  with  its  terms  as  to  any  or  all  shares  purchasable
         thereunder.

                  (d)  Payment  for  Shares.  Payment  for shares as to which an
         Option is  exercised  shall be made in such  manner and at such time or
         times  as shall be  provided  by the  Committee  in the  Option  grant.
         Payment may be made in cash or in such other manner as the Committee in
         its discretion may authorize.

                  (e)  Nontransferability  of Options. No Option or any interest
         therein shall be  transferable by the optionee other than by will or by
         the laws of descent and  distribution.  During an optionee's  lifetime,
         all  Options  shall  be  exercisable  only by such  optionee  or by the
         guardian or legal representative of the optionee.

                  (f)  Shareholder  Rights.  The holder of an Option  shall,  as
         such, have none of the rights of a shareholder.

                  (g)  Termination  of  Employment.  The  Committee  shall  have
         discretion  to  specify in the Option  grant or an  amendment  thereof,
         provisions with respect to the period, not extending beyond the term of
         the Option,  during  which the Option may be  exercised  following  the
         optionee's termination of employment.

                  (h)  Change of  Control.  Notwithstanding  the  exercisability
         schedule  governing  any  Option,  upon the  occurrence  of a Change of
         Control (as defined in Section 4.9) all Options outstanding at the time
         of such Change of Control and held by  optionees  who are  employees of
         the  Company or its  Subsidiaries  at the time of the Change of Control
         shall become  immediately  exercisable  and, unless the optionee agrees
         otherwise in writing,  shall remain  exercisable  for a period of three
         years following the optionee's termination of employment or such longer
         period as may be  provided in the  Option,  but in no event  beyond the
         term of the Option established pursuant to Section 2.1(b).

2.2      Stock Appreciation Rights in Tandem with Options

         (a) The Committee  may,  either at the time of grant of an Option or at
any time  during the term of the  Option,  grant  Stock  Appreciation  Rights or
Limited  Stock  Appreciation  Rights  with  respect to all or any portion of the
shares of Common Stock covered by such Option. A Stock Appreciation Right may be
exercised  at any time the  Option to which it relates  is then  exercisable.  A
Limited Stock  Appreciation Right may be exercised only within 60 days after the
occurrence of a Change of Control. A Stock Appreciation Right or a Limited Stock
Appreciation  Right may only be  exercised  to the extent the Option to which it
relates is  exercisable,  and shall be subject to the  conditions  applicable to
such Option. When a Stock Appreciation Right or Limited Stock Appreciation Right
is exercised,  the Option to which it relates shall cease to be  exercisable  to
the extent of the number of shares with respect to which the Stock  Appreciation
Right or Limited  Stock  Appreciation  Right is  exercised.  Similarly,  when an
Option is exercised, the Stock Appreciation Rights or Limited Stock Appreciation
Rights relating to the shares covered by such Option  exercise shall  terminate.
Any Stock Appreciation Right which is outstanding on the last day of the term of
the  related  Option  (as  determined  pursuant  to  Section  2.1(b))  shall  be
automatically exercised on such date without any action by the optionee.

         (b) Upon  exercise  of a Stock  Appreciation  Right,  the holder  shall
receive,  for each share with respect to which the Stock  Appreciation  Right is
exercised,  an amount (the  "Appreciation")  equal to the difference between the
option  price per share of the  Option  to which  the Stock  Appreciation  Right
relates and the fair market value (as determined by the Committee) of a share of
Common  Stock on the date of  exercise  of the  Stock  Appreciation  Right.  The
Appreciation  shall be payable in cash,  Common Stock, or a combination of both,
at the option of the Committee, and shall be paid within 30 days of the exercise
of the Stock Appreciation Right.

         (c)  Notwithstanding  the foregoing,  if a Stock  Appreciation Right is
exercised  within  60 days  after the  occurrence  of a Change  of  Control,  in
addition to the Appreciation and any Supplemental Payment (as defined in Section
2.3) to which the holder is  entitled,  the holder  shall  receive (in cash,  in
Common Stock,  or a combination of both, at the discretion of the Committee) (1)
the amount by which the  greater of (a) the  highest  market  price per share of
Common  Stock  during  the  60-day  period  preceding   exercise  of  the  Stock
Appreciation  Right or (b) the highest  price per share of Common  Stock (or the
cash-  equivalent  thereof as determined  by the Board of Directors)  paid by an
acquiring person during the 60-day period preceding a Change of Control, exceeds
the fair market  value of a share of Common Stock on the date of exercise of the
Stock  Appreciation  Right, plus (2) if the holder is entitled to a Supplemental
Payment,  an additional  payment,  calculated under the same formula as used for
calculating  such  holder's  Supplemental  Payment,  with  respect to the amount
referred to in clause (1) of this sentence.

         (d) Upon exercise of a Limited  Stock  Appreciation  Right,  the holder
shall  receive,  for  each  share  with  respect  to  which  the  Limited  Stock
Appreciation Right is exercised, the sum of (i) the Appreciation,  as defined in
Section  2.2(b);  (ii) any  Supplemental  Payment (as defined in Section 2.3) to
which the holder is entitled with respect to the Appreciation;  (iii) the amount
by which the greater of (a) the highest  market  price per share of Common Stock
during the 60-day period  preceding  exercise of the Limited Stock  Appreciation
Right or (b) the highest price per share of Common Stock (or the cash-equivalent
thereof as  determined by the Board of  Directors)  paid by an acquiring  person
during the 60-day period preceding a Change of Control,  exceeds the fair market
value of a share of Common  Stock on the date of exercise  of the Limited  Stock
Appreciation  Right;  and  (iv) if the  holder  is  entitled  to a  Supplemental
Payment,  an additional  payment,  calculated under the same formula as used for
calculating  such  holder's  Supplemental  Payment,  with  respect to the amount
referred to in clause (iii) of this sentence.  All of such amounts shall be paid
within 30 days of the  exercise of the Limited  Stock  Appreciation  Right,  and
shall be paid in  cash,  in  Common  Stock,  or a  combination  of both,  at the
discretion of the Committee.

2.3      Supplemental Payment on Exercise of Options or Stock Appreciation 
         Rights

         The  Committee,  either at the time of grant or at the time of exercise
of any Option or related Stock  Appreciation Right or Limited Stock Appreciation
Right, may provide for a supplemental  payment (the  "Supplemental  Payment") by
the  Company  to the  optionee  with  respect to the  exercise  of any Option or
related  Stock  Appreciation  Right or Limited  Stock  Appreciation  Right.  The
Supplemental  Payment shall be in the amount  specified by the Committee,  which
shall not exceed,  but may be equal to, the amount  necessary to pay the federal
income tax payable with respect to both  exercise of the Option or related Stock
Appreciation  Right or  Limited  Stock  Appreciation  Right and  receipt  of the
Supplemental  Payment,  assuming the optionee is taxed at the maximum  effective
federal income tax rate applicable  thereto.  The Supplemental  Payment shall be
paid in cash,  Common  Stock,  or a  combination  of both,  at the option of the
Committee.  The Supplemental Payment shall be paid within 30 days of the date of
exercise of an Option or Stock  Appreciation Right or Limited Stock Appreciation
Right (or, if later,  within 30 days of the date on which  income is  recognized
for federal income tax purposes with respect to such exercise).

2.4      Statutory Options

         Subject to the  limitations  on Option  terms set forth in Section 2.1,
the  Committee  shall have the  authority to grant (i)  incentive  stock options
within the meaning of Section 422 of the Code and (ii) Options  containing  such
terms  and  conditions  as  shall  be  required  to  qualify  such  Options  for
preferential  tax  treatment  under  the Code as in  effect  at the time of such
grant. Options granted pursuant to this Section 2.4 may contain such other terms
and  conditions  permitted by Article II of this Plan as the  Committee,  in its
discretion,  may from time to time  determine  (including,  without  limitation,
provision for Stock Appreciation  Rights,  Limited Stock Appreciation Rights and
Supplemental  Payments),  to the extent  that such terms and  conditions  do not
cause the Options to lose their  preferential  tax treatment.  To the extent the
Code and Regulations  promulgated thereunder require a plan to contain specified
provisions in order to qualify  options for  preferential  tax  treatment,  such
provisions shall be deemed to be stated in this Plan.


                              III. RESTRICTED STOCK

3.1      Terms and Conditions of Restricted Stock Awards

         Subject to the following  provisions,  all awards of  Restricted  Stock
shall be in such form and shall have such terms and conditions as the Committee,
in its discretion, may from time to time determine:

                  (a) The  Restricted  Stock award  shall  specify the number of
         shares of Restricted Stock to be awarded, the price, if any, to be paid
         by the  recipient  of the  Restricted  Stock,  and the date or dates on
         which the Restricted  Stock will vest. The vesting of Restricted  Stock
         may be conditioned upon the completion of a specified period of service
         with the Company or its Subsidiaries,  upon the attainment of specified
         performance  goals,  or upon such other  criteria as the  Committee may
         determine in its sole discretion.

                  (b)  Stock  certificates  representing  the  Restricted  Stock
         granted to an employee shall be registered in the employee's name. Such
         certificates  shall  either  be held by the  Company  on  behalf of the
         employee,  or delivered  to the  employee  bearing a legend to restrict
         transfer of the certificate  until the Restricted Stock has vested,  as
         determined by the Committee.  The Committee shall determine whether the
         employee shall have the right to vote and/or  receive  dividends on the
         Restricted Stock before it has vested. No share of Restricted Stock may
         be sold,  transferred,  assigned, or pledged by the employee until such
         share has vested in accordance  with the terms of the Restricted  Stock
         award. In the event of an employee's  termination of employment  before
         all  of  his  Restricted  Stock  has  vested,  or in  the  event  other
         conditions to the vesting of Restricted  Stock have not been  satisfied
         prior to any deadline for the satisfaction of such conditions set forth
         in the award,  the  shares of  Restricted  Stock  which have not vested
         shall be forfeited and any purchase price paid by the employee shall be
         returned to the employee.  At the time Restricted  Stock vests (and, if
         the employee has been issued legended certificates of Restricted Stock,
         upon the return of such certificates to the Company), a certificate for
         such  vested  shares  shall  be  delivered  to  the  employee  (or  the
         beneficiary  designated by the employee in the event of death), free of
         all restrictions.

                  (c)  Notwithstanding  the vesting  conditions set forth in the
         Restricted  Stock  award,  (i)  the  Committee  may in  its  discretion
         accelerate  the vesting of Restricted  Stock at any time,  and (ii) all
         shares of  Restricted  Stock shall vest upon a Change of Control of the
         Company.

3.2      Supplemental Payment on Vesting of Restricted Stock

         The Committee, either at the time of grant or at the time of vesting of
Restricted  Stock, may provide for a Supplemental  Payment by the Company to the
employee in an amount specified by the Committee which shall not exceed, but may
be equal to, the amount  necessary  to pay the federal  income tax payable  with
respect  to  both  the  vesting  of the  Restricted  Stock  and  receipt  of the
Supplemental  Payment,  assuming the employee is taxed at the maximum  effective
federal  income tax rate  applicable  thereto and has not  elected to  recognize
income with  respect to the  Restricted  Stock  before the date such  Restricted
Stock vests. The Supplemental  Payment shall be paid within 30 days of each date
that Restricted  Stock vests.  The  Supplemental  Payment shall be paid in cash,
Common Stock, or a combination of both, at the discretion of the Committee.


                            IV. ADDITIONAL PROVISIONS

4.1      General Restrictions

         Each award under the Plan shall be subject to the requirement  that, if
at any time the Committee shall determine that (i) the listing,  registration or
qualification  of the shares of Common Stock subject or related thereto upon any
securities  exchange  or under any state or federal  law, or (ii) the consent or
approval  of any  government  regulatory  body,  or  (iii) an  agreement  by the
recipient of an award with respect to the  disposition of shares of Common Stock
is necessary or desirable (in connection with any requirement or  interpretation
of any federal or state  securities  law, rule or regulation) as a condition of,
or in connection  with, the granting of such award or the issuance,  purchase or
delivery of shares of Common Stock thereunder, such award may not be consummated
in whole or in part unless such listing, registration,  qualification,  consent,
approval  or  agreement  shall  have  been  effected  or  obtained  free  of any
conditions not acceptable to the Committee.

4.2      Adjustments for Changes in Capitalization

         In the event of a reorganization,  recapitalization, stock split, stock
dividend, combination of shares, rights offer, liquidation, dissolution, merger,
consolidation,  spin-off,  sale of  assets,  payment  of an  extraordinary  cash
dividend,  or any other  change  in or  affecting  the  corporate  structure  or
capitalization of the Company,  the Committee shall make appropriate  adjustment
in the  number  and  kind  of  shares  authorized  by the  Plan  (including  any
limitations  on  individual  awards),  in the  number,  price or kind of  shares
covered by the awards and in any outstanding awards under the Plan.

4.3      Amendments

         (a) The Board of  Directors  may  amend the Plan from time to time.  No
such amendment shall require  approval by the  stockholders  unless  stockholder
approval is required by applicable law or stock exchange requirements.

         (b) The  Committee  shall  have the  authority  to amend  any  grant to
include any provision which, at the time of such amendment,  is authorized under
the terms of the Plan; provided,  however,  that (1) no outstanding award may be
revoked or altered in a manner  unfavorable  to the holder  without  the written
consent of the holder,  and (2) no outstanding Option may be altered in a manner
that reduces the option price (except as provided in Section 4.2).

4.4      Cancellation of Awards

         Any award  granted  under the Plan may be canceled at any time with the
consent of the  holder  and a new award may be  granted  to such  holder in lieu
thereof,  which  award  may,  in the  discretion  of the  Committee,  be on more
favorable terms and conditions than the canceled award; provided,  however, that
any Option  that is granted  in lieu of a canceled  Option  shall have an option
price at least equal to the option price of the canceled Option.

4.5      Withholding

         (a) Whenever  the Company  proposes or is required to issue or transfer
shares of Common  Stock  under the Plan,  the  Company  shall  have the right to
require the holder to remit to the Company an amount  sufficient  to satisfy any
federal,  state or local  withholding tax liability prior to the delivery of any
certificate for such shares.  Whenever under the Plan payments are to be made in
cash, such payments shall be net of an amount sufficient to satisfy any federal,
state or local withholding tax liability.

         (b) An employee entitled to receive Common Stock under the Plan who has
not received a cash  Supplemental  Payment may elect to have the federal,  state
and local tax  liability (or a specified  portion  thereof) with respect to such
Common Stock satisfied by having the Company  withhold from the shares otherwise
deliverable  to the employee  shares of Common Stock having a value equal to the
amount of the tax liability to be satisfied with respect to the Common Stock. An
election to have all or a portion of the tax  liability  satisfied  using Common
Stock shall comply with such requirements as may be imposed by the Committee and
shall be subject to the  disapproval of the Committee (if expressed prior to the
making of such election).

4.6      Non-Assignability

         Except as expressly provided in the Plan, no award under the Plan shall
be assignable or  transferable  by the holder  thereof  except by will or by the
laws of descent and  distribution.  During the life of the holder,  awards under
the Plan shall be  exercisable  only by such holder or by the  guardian or legal
representative of such holder.

4.7      Non-Uniform Determinations

         Determinations  by the  Committee  under the Plan  (including,  without
limitation,  determinations  of the persons to receive awards;  the form, amount
and  timing of such  awards;  the terms and  provisions  of such  awards and the
agreements  evidencing  same;  and  provisions  with respect to  termination  of
employment) need not be uniform and may be made by it selectively  among persons
who receive,  or are eligible to receive,  awards under the Plan, whether or not
such persons are similarly situated.

4.8      No Guarantee of Employment

         The grant of an award under the Plan shall not  constitute an assurance
of continued employment for any period.

4.9      Change of Control

                  A "Change of Control" shall mean:

                  (i) The acquisition by any individual, entity or group (within
         the meaning of Section  13(d)(3) or  14(d)(2) of the  Exchange  Act) (a
         "Person")  of  beneficial  ownership  (within the meaning of Rule 13d-3
         promulgated  under the  Exchange  Act) of 20% or more of either (1) the
         then   outstanding   shares  of  common   stock  of  the  Company  (the
         "Outstanding  Common  Stock") or (2) the  combined  voting power of the
         then  outstanding  voting  securities  of the Company  entitled to vote
         generally  in  the  election  of  directors  (the  "Outstanding  Voting
         Securities");  provided,  however, that for purposes of this subsection
         (i),  the  following  acquisitions  shall  not  constitute  a Change of
         Control:  (A)  any  acquisition  directly  from  the  Company,  (B) any
         acquisition by the Company, (C) any acquisition by any employee benefit
         plan (or related  trust)  sponsored or maintained by the Company or any
         corporation  controlled  by the Company or (D) any  acquisition  by any
         corporation  pursuant to a transaction which complies with clauses (A),
         (B) and (C) of subsection (iii); or

                  (ii) Individuals  who, as of December 1, 1995,  constitute the
         Board of  Directors  (the  "Incumbent  Board")  cease for any reason to
         constitute  at least a majority  of the Board of  Directors;  provided,
         however,  that any  individual  becoming a director  subsequent to such
         date whose  election,  or  nomination  for  election  by the  Company's
         shareholders,  was  approved  by a vote of at least a  majority  of the
         directors then  comprising  the Incumbent  Board shall be considered as
         though  such  individual  were a member  of the  Incumbent  Board,  but
         excluding,   for  this  purpose,  any  such  individual  whose  initial
         assumption  of office  occurs  as a result  of an actual or  threatened
         election  contest  with respect to the election or removal of directors
         or other actual or threatened solicitation of proxies or consents by or
         on behalf of a Person other than the Board of Directors; or

                  (iii)   Consummation   of   a   reorganization,    merger   or
         consolidation or sale or other  disposition of all or substantially all
         of the assets of the Company (a "Business Combination"),  in each case,
         unless,  following such Business Combination,  (A) all or substantially
         all of the  individuals  and entities who were the  beneficial  owners,
         respectively,  of the Outstanding  Common Stock and Outstanding  Voting
         Securities immediately prior to such Business Combination  beneficially
         own, directly or indirectly,  more than 50% of, respectively,  the then
         outstanding shares of common stock and the combined voting power of the
         then outstanding  voting  securities  entitled to vote generally in the
         election of directors, as the case may be, of the corporation resulting
         from  such  Business  Combination  (including,  without  limitation,  a
         corporation  which as a result of such  transaction owns the Company or
         all or  substantially  all of the Company's  assets either  directly or
         through one or more subsidiaries) in substantially the same proportions
         as their ownership,  immediately prior to such Business Combination, of
         the Outstanding Common Stock and Outstanding Voting Securities,  as the
         case may be, (B) no Person  (excluding any  corporation  resulting from
         such  Business  Combination  or any  employee  benefit plan (or related
         trust) of the Company or such corporation  resulting from such Business
         Combination) beneficially owns, directly or indirectly, 20% or more of,
         respectively,  the  then  outstanding  shares  of  common  stock of the
         corporation  resulting  from such Business  Combination or the combined
         voting  power  of  the  then  outstanding  voting  securities  of  such
         corporation  except to the extent that such ownership  existed prior to
         the Business  Combination and (C) at least a majority of the members of
         the board of directors of the corporation  resulting from such Business
         Combination  were  members  of the  Incumbent  Board at the time of the
         execution  of the initial  agreement,  or of the action of the Board of
         Directors, providing for such Business Combination.

4.10     Duration and Termination

         (a) The  Plan  shall  be of  unlimited  duration.  Notwithstanding  the
foregoing,  no incentive  stock option (within the meaning of Section 422 of the
Code) shall be granted under the Plan after April 26, 2005,  but awards  granted
prior to such date may extend beyond such date, and the terms of this Plan shall
continue to apply to all awards granted hereunder.

         (b) The Board of Directors may discontinue or terminate the Plan at any
time.  Such action shall not impair any of the rights of any holder of any award
outstanding on the date of the Plan's  discontinuance or termination without the
holder's written consent.

         EXECUTIVE  SEVERANCE  AGREEMENT,  dated  as of July  23,  1998,  by and
between  Sonat  Inc.,  a  Delaware  corporation ("Sonat"),  and Ronald L. Kuehn,
Jr. ("Executive").

         WHEREAS, the Executive Compensation Committee of the Board of Directors
of Sonat has  recommended,  and the Board of Directors has approved,  that Sonat
enter into  severance  agreements  with key executives who are from time to time
designated by the Executive Compensation Committee;

         WHEREAS,  should  Sonat become  subject to any  proposed or  threatened
Change of Control (as hereinafter  defined),  the Board of Directors believes it
imperative  that Sonat and the Board of Directors be able to rely upon Executive
to continue in Executive's position,  and that Sonat be able to receive and rely
upon Executive's advice, if requested, as to the best interests of Sonat and its
stockholders  without concern that Executive might be distracted by the personal
uncertainties and risks created by such a proposal or threat;

         WHEREAS,  should  Sonat  receive  any such  proposals,  in  addition to
Executive's  regular  duties,  Executive  may be  called  upon to  assist in the
assessment of such proposals, to advise management and the Board of Directors as
to  whether  such  proposals  would be in the best  interests  of Sonat  and its
stockholders,  and to take such other  actions as the Board of  Directors  might
determine to be appropriate;

         WHEREAS,  Executive is a key executive and, pursuant to action taken by
the Executive Compensation Committee and the Board of Directors,  has previously
entered into a severance agreement with Sonat; and

         WHEREAS,  the  Executive   Compensation  Committee  and  the  Board  of
Directors have approved certain revisions to such severance agreement, Executive
agrees to such  revisions,  and  Executive and Sonat desire to amend and restate
such severance agreement in order to consolidate the terms thereof into a single
document;

         NOW, THEREFORE, Sonat and Executive agree as follows:

         1. Services During Certain Events. In the event a third person begins a
tender or exchange  offer,  circulates a proxy to  stockholders,  or takes other
steps to effect a Change of Control,  Executive agrees not to voluntarily  leave
the employ of Sonat or its subsidiaries, and to render the services contemplated
in the  recitals to this  Agreement,  until the third  person has  abandoned  or
terminated  his  efforts  to  effect a Change  of  Control  or until a Change of
Control has occurred.

         2.  Termination  Following  Change of  Control.  Except as  provided in
Section 4 hereof,  Sonat will provide or cause to be provided to  Executive  the
rights and benefits  described in Section 3 hereof in the event that Executive's
employment is terminated:

                  (a) at any time  within  three  years  following  a Change  of
         Control by Sonat or its subsidiaries for reasons other than for "cause"
         (as such  term is  defined  in  Section 4  hereof)  or other  than as a
         consequence of Executive's death, permanent disability or retirement at
         or after April 30, 2001 ("Normal  Retirement  Date") as provided  under
         Sonat's Retirement Plan as in effect immediately preceding such date;

                  (b) at any time  within  three  years  following  a Change  of
         Control by Executive  following the  occurrence of any of the following
         events without Executive's written consent:

                           (i) the  assignment  of  Executive  to any  duties or
                  responsibilities   that  are  inconsistent   with  Executive's
                  position,  duties,   responsibilities  or  status  immediately
                  preceding  such  Change of Control,  or a change in  reporting
                  responsibilities or titles in effect at such time resulting in
                  a reduction of Executive's responsibilities or position;

                           (ii)  the  reduction  of  Executive's  annual  salary
                  (including any deferred portions thereof), annual or long-term
                  cash or stock  bonus  opportunities,  or level of  benefits or
                  supplemental compensation; or

                           (iii)  the   transfer  of  Executive  to  a  location
                  requiring  a change in  Executive's  residence  or a  material
                  increase  in  the  amount  of  travel  normally   required  of
                  Executive in connection with Executive's employment; or

                  (c) by  Executive  for any reason  during  the  30-day  period
         immediately  following the first  anniversary of the date of the Change
         of Control.

                  For  purposes of this  Agreement,  "Change of  Control"  shall
mean:

                  A. The acquisition by any individual,  entity or group (within
the meaning of Section  13(d)(3) or 14(d)(2) of the  Securities  Exchange Act of
1934,  as amended (the  "Exchange  Act")) (a "Person") of  beneficial  ownership
(within the meaning of Rule 13(d)-3  promulgated  under the Exchange Act) of 20%
or more of either (i) the then outstanding  shares of common stock of Sonat (the
"Outstanding  Common  Stock")  or (ii)  the  combined  voting  power of the then
outstanding  voting  securities  of  Sonat  entitled  to vote  generally  in the
election of directors (the "Outstanding Voting Securities");  provided, however,
that for purposes of this  subsection  A, the following  acquisitions  shall not
constitute a Change of Control:  (i) any acquisition  directly from Sonat,  (ii)
any acquisition by Sonat, (iii) any acquisition by any employee benefit plan (or
related trust) sponsored or maintained by Sonat or any corporation controlled by
Sonat or (iv) any acquisition by any corporation pursuant to a transaction which
complies with clauses (i), (ii) and (iii) of subsection C; or

                  B.  Individuals  who, as of the date  hereof,  constitute  the
Board of Directors (the "Incumbent Board") cease for any reason to constitute at
least  a  majority  of the  Board  of  Directors;  provided,  however  that  any
individual becoming a director subsequent to the date hereof whose election,  or
nomination  for election by Sonat's  shareholders,  was approved by a vote of at
least a majority of the directors then  comprising the Incumbent  Board shall be
considered as though such individual were a member of the Incumbent  Board,  but
excluding,  for this purpose,  any such individual  whose initial  assumption of
office  occurs  as a result of an actual or  threatened  election  contest  with
respect to the election or removal of  directors  or other actual or  threatened
solicitation  of proxies or consents by or on behalf of a Person  other than the
Board of Directors; or

                  C. Consummation of a  reorganization,  merger or consolidation
or sale or other  disposition of all or substantially all of the assets of Sonat
(a  "Business  Combination"),  in each case,  unless,  following  such  Business
Combination,  (i) all or  substantially  all of the individuals and entities who
were the beneficial  owners,  respectively,  of the Outstanding Common Stock and
Outstanding  Voting Securities  immediately  prior to such Business  Combination
beneficially own, directly or indirectly,  more than 50% of,  respectively,  the
then  outstanding  shares of common stock and the  combined  voting power of the
then outstanding voting securities entitled to vote generally in the election of
directors,  as the case may be, of the corporation  resulting from such Business
Combination (including,  without limitation,  a corporation which as a result of
such transaction owns Sonat or all or substantially all of Sonat's assets either
directly  or  through  one or  more  subsidiaries)  in  substantially  the  same
proportions as their ownership,  immediately prior to such Business Combination,
of the Outstanding Common Stock and Outstanding  Voting Securities,  as the case
may be, (ii) no Person  (excluding any corporation  resulting from such Business
Combination  or any employee  benefit  plan (or related  trust) of Sonat or such
corporation  resulting  from  such  Business  Combination)   beneficially  owns,
directly  or  indirectly,  20% or more of,  respectively,  the then  outstanding
shares  of  common  stock  of  the  corporation  resulting  from  such  Business
Combination  or the  combined  voting  power  of  the  then  outstanding  voting
securities of such corporation  except to the extent that such ownership existed
prior to the Business  Combination  and (iii) at least a majority of the members
of the board of  directors  of the  corporation  resulting  from  such  Business
Combination  were members of the Incumbent Board at the time of the execution of
the initial agreement, or of the action of the Board of Directors, providing for
such Business Combination.

         3.  Rights  and  Benefits  upon  Termination.   In  the  event  of  the
termination of Executive's  employment under any of the  circumstances set forth
in  Section 2 hereof  ("Termination"),  Sonat  agrees to  provide or cause to be
provided to Executive the following rights and benefits:

                  (a)  Lump  Sum  Payment  at  Termination.  Executive  shall be
         entitled to receive within 30 days of Termination a lump-sum payment in
         cash in the amount of three times Executive's Earnings (as such term is
         defined in this Section  3(a));  provided,  however,  that if there are
         fewer  than  36  months  remaining  from  the  date of  Termination  to
         Executive's  Normal Retirement Date, the amount calculated  pursuant to
         this  paragraph  will  be  reduced  by  multiplying  such  amount  by a
         fraction, the numerator of which is the number of months (including any
         fraction of a month) so remaining to Executive's Normal Retirement Date
         and the denominator of which is 36.

                           For purposes of this Agreement, "Earnings" shall mean
         the sum of (1)  Executive's  Annual  Base Pay (as defined  below),  (2)
         Executive's  Recent Cash Bonus (as defined below),  and (3) Executive's
         Recent Long-Term Compensation (as defined below).

                           "Annual  Base Pay" shall mean the  greater of (1) the
         annualized  amount of Executive's rate of base pay (as shown in Sonat's
         payroll records)  immediately before the Change of Control, and (2) the
         annualized  amount of Executive's rate of base pay (as shown in Sonat's
         payroll records) immediately before the date of Termination.

                           "Recent   Cash  Bonus"  shall  mean  the  product  of
         Executive's Annual Base Pay multiplied by the greater of:

                                            (1)  the  quotient   determined   by
                                    dividing (a) the sum of the amounts  payable
                                    to Executive upon the occurrence of a Change
                                    of  Control   pursuant  to  Section  2.6  of
                                    Sonat's  Performance Award Plan, Section 2.6
                                    of Sonat's Cash Bonus Plan,  and Section 2.6
                                    of Sonat's  Performance Award and Cash Bonus
                                    Plan (regardless of whether such amounts are
                                    paid in a lump sum or in  installments),  by
                                    (b) the  annualized  amount  of  Executive's
                                    rate  of  base  pay  (as  shown  in  Sonat's
                                    payroll  records)   immediately  before  the
                                    Change of Control; and

                                            (2) the highest quotient determined,
                                    for the calendar year in which the Change of
                                    Control  occurs  and  for  each  of the  two
                                    preceding  calendar  years,  by dividing (a)
                                    the sum of the  bonuses  paid  to  Executive
                                    under the  Performance  Award Plan, the Cash
                                    Bonus Plan,  and the  Performance  Award and
                                    Cash  Bonus Plan  during the first  calendar
                                    quarter of such calendar year (including for
                                    this purpose any amount receipt of which was
                                    deferred by the Executive

                                                     Compensation      Committee
                                    pursuant to the terms of such  Plans,  or by
                                    Executive  pursuant  to the terms of Sonat's
                                    Deferred  Compensation  Plan),  by  (b)  the
                                    annualized  amount  of  Executive's  rate of
                                    base  pay  (as  shown  in  Sonat's   payroll
                                    records)  at  the  time  of  such   payment.
                                    Notwithstanding  the  foregoing,  if at  the
                                    time of the  Change of  Control  the  amount
                                    paid to Executive  under clause (1) above is
                                    with   respect   to  a   bonus   opportunity
                                    established for the preceding  calendar year
                                    (or  a  portion   thereof),   the  quotients
                                    calculated pursuant to this clause (2) shall
                                    be determined for each of the three calendar
                                    years before the calendar  year in which the
                                    Change of Control occurs.

                  "Recent  Long-Term  Compensation"  shall  mean the  product of
Executive's  Annual  Base  Pay  multiplied  by  the  average  of  the  quotients
determined,  for each of the three  calendar years before the date of the Change
of Control,  by dividing (a) the Grant Value (as defined  below) for the regular
annual  grant of stock  options  and/or  restricted  stock  made  under  Sonat's
Executive Award Plan during the fourth calendar quarter of such calendar year by
(b) the annualized  amount of Executive's  rate of base pay (as shown in Sonat's
payroll records) on the date of such grant. Grant Value shall mean, with respect
to any such annual grant during any fourth calendar quarter,  the sum of (1) the
product of the number of stock  options  granted to Executive  multiplied by the
value of each such stock option at the date of grant (as  determined or approved
by the  Executive  Compensation  Committee  at the date of grant),  plus (2) the
product  of the  number of shares  of  restricted  stock  granted  to  Executive
multiplied by the value of a share of restricted  stock at the date of grant (as
determined  or approved by the Executive  Compensation  Committee at the date of
grant).  Notwithstanding  the foregoing,  if the Change of Control occurs in the
fourth calendar quarter of a calendar year and after the regular annual grant of
stock options and/or restricted stock for such year, the quotients calculated as
described  above  shall be  determined  for such  calendar  year and for the two
preceding  calendar years.  If the quotient  determined for any calendar year is
zero, such quotient shall be disregarded  (and no additional  quotients shall be
calculated in substitution therefor).

                  (b)  Retirement  Benefits.  If at  the  date  of  Termination,
         Executive  is not  otherwise  entitled  to receive an early  retirement
         benefit under the terms of a qualified defined benefit  retirement plan
         of Sonat or its subsidiaries,  Sonat shall pay in cash to Executive, in
         the form of a cash  lump sum (a  "Severance  Retirement  Benefit"),  an
         amount  equal to the  Actuarial  Equivalent  (as defined  below) of the
         excess,  if any, of (1) the monthly benefit  calculated under the early
         retirement  provisions of the Retirement Plan (as in effect immediately
         prior to the Change of Control),  using the early retirement  reduction
         factors  applicable as of the later of age 55 or Executive's actual age
         at the date of  Termination,  and (2) the  monthly  benefit  payable to
         Executive  under  the  Retirement  Plan  (as in  effect  on the date of
         Executive's  Termination),  assuming  the  following  for  purposes  of
         clauses (1) and (2): (A) the benefit is payable in the form of a single
         life annuity as of the later of the date  Executive  attains age 55 and
         the  date of  Termination;  (B) the  benefit  is  calculated  based  on
         Executive's  actual service and actual earnings  history at the date of
         Termination;  (C) Executive is fully vested in the benefit; and (D) the
         benefit is calculated under the assumption that Sections 401(a)(17) and
         415 of the Internal Revenue Code of 1986, as amended (the "Code"),  are
         nonexistent  and the  provisions of the Retirement  Plan  incorporating
         such Code Sections are  inoperative.  The  determination of Executive's
         Severance  Retirement  Benefit  shall  not  include  the  value  of any
         benefits under the "cash balance"  portion of the Retirement  Plan. The
         Severance  Retirement Benefit shall be paid as soon as practicable (and
         within  30  days)  after  the date of  Termination,  and  shall  not be
         affected  by the  settlement  option  or  date of  commencement  of any
         benefits   actually  payable  under  the  Retirement  Plan  or  Sonat's
         Supplemental Benefit Plan.

                  (c) Survivors' Benefits. If Executive is entitled to receive a
         Severance  Retirement  Benefit  under  Section  3(b) and on the date of
         Termination  Executive  either (1) has an Eligible Spouse (as such term
         is defined in the Retirement Plan as in effect immediately prior to the
         Change of Control,  and determined as if Executive had died on the date
         of  Termination),  or (2) does not have an Eligible  Spouse (as defined
         above)  but does have one or more  Eligible  Children  (as such term is
         defined in the Retirement  Plan as in effect  immediately  prior to the
         Change of Control,  and determined as if Executive had died on the date
         of  Termination),  Sonat shall pay to Executive,  in the form of a cash
         lump sum (the "Severance Survivors'  Benefit"),  an amount equal to the
         Actuarial  Equivalent of the monthly survivors' benefit payable to such
         Eligible  Spouse or  Eligible  Children  (as the case may be) under the
         Retirement  Plan  (as in  effect  immediately  prior to the  Change  of
         Control) with respect to Executive if  Executive's  retirement  benefit
         were  calculated  under the early  retirement  provisions of such plan,
         using the early retirement  benefit reduction factors  applicable as of
         the  later  of  age  55 or  Executive's  actual  age  at  the  date  of
         Termination,  and assuming (A) the retirement  benefit is payable as of
         the  later  of the  date  Executive  attains  age 55 and  the  date  of
         Termination;   (B)  the  retirement  benefit  is  calculated  based  on
         Executive's  actual service and actual earnings  history at the date of
         Termination;  (C) Executive is fully vested in the retirement  benefit;
         and (D) the retirement  benefit and  survivors'  benefit are calculated
         under  the  assumption  that  Code  Sections  401(a)(17)  and  415  are
         nonexistent  and Section 7.10 and the provisions of the Retirement Plan
         incorporating  the  limitations  contained  in such Code  Sections  are
         inoperative.  The  determination  of Executive's  Severance  Survivors'
         Benefit  shall not  include the value of any  benefits  under the "cash
         balance" portion of the Retirement Plan.

         The Severance  Survivors'  Benefit shall be paid as soon as practicable
         (and  within 30 days)  after the date of  Termination  and shall not be
         affected  by any  settlement  option  or  date of  commencement  of any
         benefits actually payable under the Retirement Plan or the Supplemental
         Benefit Plan.

                  (d)  Insurance  and  Other  Special  Benefits.  To the  extent
         Executive  is  eligible  thereunder,  Executive  shall  continue  to be
         covered by the life and dependent  life  insurance,  medical and dental
         insurance, and accident and disability insurance plans of Sonat and its
         subsidiaries  or any successor plan or program in effect at Termination
         for  employees in the same class or category as  Executive,  subject to
         the  terms  of  such  plans  and to  Executive's  making  any  required
         contributions thereto. In the event Executive is ineligible to continue
         to be so covered  under the terms of any such  benefit plan or program,
         or in the event  Executive is eligible but the benefits  applicable  to
         Executive are not substantially  equivalent to the benefits  applicable
         to Executive immediately prior to Termination, then, for a period of 36
         months following  Termination (or until  Executive's  Normal Retirement
         Date,  whichever is sooner),  Sonat shall  provide  such  substantially
         equivalent benefits, or such additional benefits as may be necessary to
         make the benefits applicable to Executive  substantially  equivalent to
         those in effect before  Termination,  through other sources;  provided,
         however,  that if during such period  Executive  should  enter into the
         employ of another company or firm which provides  substantially similar
         benefit coverage,  Executive's  participation in the comparable benefit
         provided by Sonat either  directly or through such other  sources shall
         cease.  Nothing  contained in this paragraph shall be deemed to require
         or permit termination or restriction of Executive's  coverage under any
         plan or program of Sonat or any of its  subsidiaries  or any  successor
         plan or program  thereto to which Executive is entitled under the terms
         of  such  plan or  program,  whether  at the end of the  aforementioned
         36-month  period or at any other time.  Executive  shall be entitled to
         continuation  ("COBRA")  coverage  under  Code  Section  4980B upon the
         termination  of the  coverage  provided  under this Section 3(d) to the
         same  extent  as if such  coverage  had not  been  provided.  Upon  the
         occurrence  of  both  (1)  the  termination  of  the  medical  coverage
         (including any COBRA coverage elected by Executive) provided under this
         Section 3(d), and (2) Executive's attainment of age 55, Executive shall
         be eligible  for such  retiree  medical  coverage  as may be  available
         generally to early or normal retirees of Sonat, or to former  employees
         in the same class or  category  as  Executive,  subject to the terms of
         such  coverage and to  Executive's  making any  required  contributions
         thereto.

                  (e) Relocation  Assistance.  Should  Executive move his or her
         residence in order to pursue other business  opportunities within three
         years  of  the  date  of  Termination  (or  until  Executive's   Normal
         Retirement Date, whichever is sooner),  Sonat shall reimburse Executive
         for any expenses  incurred in that relocation  (including taxes payable
         on the  reimbursement)  which are not  reimbursed by another  employer;
         provided,   however,   that   Executive   shall  be  entitled  to  such
         reimbursement with respect to only one such relocation, it being agreed
         that in the event of more than one such relocation,  Executive shall be
         entitled to specify the relocation for which reimbursement hereunder is
         to be made.  Benefits under this provision will include the assistance,
         at no  cost  to  Executive,  in  selling  Executive's  home  and  other
         assistance  which was  customarily  provided to executives  transferred
         within Sonat or between Sonat and its subsidiaries  prior to the Change
         of Control.

                  (f) Other Benefit Plans. The specific arrangements referred to
         in this Section 3 are not intended to exclude Executive's participation
         in other benefit plans in which  Executive  currently  participates  or
         which are  available to executive  personnel  generally in the class or
         category of Executive or to preclude other  compensation or benefits as
         may be authorized by the Board of Directors from time to time.

                  (g) Duty to  Mitigate.  Executive's  entitlement  to  benefits
         hereunder  shall not be  governed  by any duty to  mitigate  damages by
         seeking  further  employment  nor  offset  by  any  compensation  which
         Executive may receive from future employment.

                  (h) Payment Obligations Absolute. Sonat's obligation to pay or
         cause to be paid to Executive the benefits and to make the arrangements
         provided in this  Section 3 shall be  absolute  and  unconditional  and
         shall  not  be  affected  by  any  circumstances,   including,  without
         limitation,  any  setoff,  counterclaim,  recoupment,  defense or other
         right,  which Sonat may have  against  Executive  or anyone  else.  All
         amounts  payable  by or on  behalf  of  Sonat  hereunder  shall be paid
         without  notice or demand.  Each and every payment made hereunder by or
         on behalf of Sonat shall be final and Sonat and its subsidiaries  shall
         not, for any reason whatsoever, seek to recover all or any part of such
         payment from Executive or from whomever shall be entitled thereto.

                  (i) Actuarial Equivalent.  "Actuarial Equivalent" shall mean a
         benefit actuarially equal in value to the value of a given benefit in a
         given form or schedule, based upon (1) the 1983 Group Annuity Mortality
         Table  (or,  if  different,  the  mortality  table  or  tables  used to
         calculate  Actuarial  Equivalents  under the Retirement  Plan as of the
         date on which an Actuarial  Equivalent is being  determined  under this
         Agreement) and (2) an interest rate equal to the yield on new 7-12 year
         AA-rated general  obligation  tax-exempt bonds as determined by Merrill
         Lynch & Co.  (or its  affiliates)  and  published  in The  Wall  Street
         Journal  (or  other   financial   publication)   on  the  business  day
         immediately preceding the date of Executive's  Termination (or, if such
         yield is not so  determined  and published on such business day, on the
         most  immediately  preceding  day on which such yield was so determined
         and published);  provided,  however, that if such yield has not been so
         determined  and  published   within  90  days  prior  to  the  date  of
         Executive's  Termination,  the  interest  rate  shall  be the  yield on
         substantially similar securities on the business day preceding the date
         of Executive's  Termination as determined by AmSouth Bank N.A. upon the
         request of either Sonat or Executive.

                  The  Severance   Survivors'  Benefit  shall  be  valued  as  a
         reversionary  annuity  commencing  upon  the  death of  Executive.  For
         purposes of calculating the Severance  Survivors' Benefit, (1) it shall
         be assumed that Executive, Executive's Eligible Spouse, and Executive's
         Eligible  Children  do not die before  the later of the date  Executive
         attains  age 55 and the  date of  Executive's  Termination,  and (2) if
         Executive has Eligible Children (but not an Eligible Spouse),  it shall
         be assumed that each Eligible Child remains an Eligible Child until the
         date such Eligible  Child  attains age 25 and that such Eligible  Child
         does not die before such date.

         4.  Conditions  to the  Obligations  of  Sonat.  Sonat  shall  have  no
obligation  to  provide  or cause to be  provided  to  Executive  the rights and
benefits  described in Section 3 hereof if either of the following  events shall
occur:

                  (a) Termination  for Cause.  Sonat or its  subsidiaries  shall
         terminate  Executive's  employment  for  "cause".  For purposes of this
         Agreement, termination of employment for "cause" shall mean termination
         solely for dishonesty,  conviction of a felony, or willful unauthorized
         disclosure of confidential information of Sonat.

                  (b)  Resignation as Director.  Executive  shall not,  promptly
         after Termination and upon receiving a written request to do so, resign
         as a director  and/or officer of each subsidiary and affiliate of Sonat
         of which Executive is then serving as a director and/or officer.

         5.       Confidentiality; Non-Solicitation; Cooperation.

         (a)  Confidentiality.  Executive  agrees  that at all  times  following
Termination,  Executive  will not,  without the prior written  consent of Sonat,
disclose to any person,  firm or  corporation  any  confidential  information of
Sonat or its subsidiaries which is now known to Executive or which hereafter may
become known to Executive as a result of  Executive's  employment or association
with Sonat and which could be helpful to a competitor, unless such disclosure is
required under the terms of a valid and effective  subpoena or order issued by a
court or  governmental  body;  provided,  however,  that the foregoing shall not
apply to confidential  information which becomes publicly  disseminated by means
other than a breach of this Agreement.

         (b) Non-Solicitation. Executive agrees that for a period of three years
following the date of Termination (or until Executive's  Normal Retirement Date,
whichever is sooner)  Executive will not induce,  either directly or indirectly,
any employee of senior to manager level of Sonat or any of its  subsidiaries  to
terminate his or her employment.

         (c)  Cooperation.   Executive  agrees  that,  at  all  times  following
Termination,  Executive will furnish such information and render such assistance
and cooperation as may reasonably be requested in connection with any litigation
or legal proceedings concerning Sonat or any of its subsidiaries (other than any
legal proceedings  concerning Executive's  employment).  In connection with such
cooperation, Sonat will pay or reimburse Executive for reasonable expenses.

         (d) Remedies for Breach.  It is recognized that damages in the event of
breach of this Section 5 by Executive would be difficult, if not impossible,  to
ascertain,  and it is  therefore  agreed that Sonat,  in addition to and without
limiting  any  other  remedy or right it may  have,  shall  have the right to an
injunction  or other  equitable  relief in any court of competent  jurisdiction,
enjoining  any such breach,  and  Executive  hereby  waives any and all defenses
Executive  may have on the ground of lack of  jurisdiction  or competence of the
court to grant such an injunction or other  equitable  relief.  The existence of
this right shall not preclude  Sonat from pursuing any other rights and remedies
at law or in equity which Sonat may have.

         6. Certain Additional Payments by Sonat. (a) Anything in this Agreement
to the contrary  notwithstanding  and except as set forth below, in the event it
shall be  determined  that any  payment or  distribution  by Sonat to or for the
benefit of  Executive,  or any benefit,  arrangement  regarding  the exercise or
vesting of options,  restricted  stock,  or other  securities of Sonat, or other
plan,  agreement or arrangement  regarding a change of control of Sonat (whether
determined pursuant to the terms of this Agreement or otherwise,  but determined
without  regard to any additional  payments  required under this Section 6) (any
such payment,  distribution,  benefit,  arrangement,  plan,  or agreement  being
referred  to as a  "Payment")  would be subject  to the  excise  tax  imposed by
Section 4999 of the Code or any interest or penalties  are incurred by Executive
with  respect  to such  excise  tax (such  excise  tax,  together  with any such
interest and penalties,  are hereinafter collectively referred to as the "Excise
Tax"),  then  Executive  shall be entitled to receive an  additional  payment (a
"Gross-Up  Payment")  in an amount such that after  payment by  Executive of all
federal,  state, local,  employment and payroll taxes (including any interest or
penalties imposed with respect to such taxes),  including,  without  limitation,
any federal,  state,  local,  employment and payroll taxes (and any interest and
penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up
Payment, Executive retains an amount of the Gross-Up Payment equal to the Excise
Tax imposed upon the Payments.  Notwithstanding the foregoing provisions of this
Section 6(a), if it shall be determined that Executive is entitled to a Gross-Up
Payment,  but that  Executive,  after  taking into  account the Payments and the
Gross-Up Payment,  would not receive a net after-tax benefit of at least $50,000
(taking into account both federal,  state,  local,  employment and payroll taxes
and any Excise  Tax) as  compared to the net  after-tax  proceeds  to  Executive
resulting  from an  elimination  of the Gross-Up  Payment and a reduction of the
Payments,  in the aggregate,  to an amount (the "Reduced  Amount") such that the
receipt of  Payments  would not give rise to any Excise  Tax,  then no  Gross-Up
Payment shall be made to Executive and the Payments, in the aggregate,  shall be
reduced to the Reduced Amount.

         (b)  Subject to the  provisions  of Section  6(c),  all  determinations
required to be made under this Section 6, including  whether and when a Gross-Up
Payment is required and the amount of such Gross-Up  Payment and the assumptions
to be utilized in arriving at such determination, shall be made by Ernst & Young
LLP or such other  certified  public  accounting  firm as may be  designated  by
Executive  (the  "Accounting  Firm"),  which shall provide  detailed  supporting
calculations  both to Sonat and Executive within 15 business days of the receipt
of notice from  Executive  that there has been a Payment or such earlier time as
is  requested  by Sonat.  In the event  that the  Accounting  Firm is serving as
accountant or auditor for the individual,  entity or group effecting a Change of
Control,  Executive shall appoint another nationally  recognized accounting firm
to make the determinations  required hereunder (which accounting firm shall then
be referred to as the Accounting Firm  hereunder).  All fees and expenses of the
Accounting  Firm shall be borne solely by Sonat.  Any Gross-Up  Payment shall be
paid by Sonat to  Executive  within five days of the  receipt of the  Accounting
Firm's determination.  Any determination by the Accounting Firm shall be binding
upon Sonat and Executive.  As a result of the  uncertainty in the application of
Section  4999  of the  Code  at the  time of the  initial  determination  by the
Accounting Firm hereunder,  it is possible that Gross-Up Payments which will not
have been made by Sonat should have been made ("Underpayment"),  consistent with
the calculations required to be made hereunder. In the event that Sonat exhausts
its remedies  pursuant to Section 6(c) and  Executive  thereafter is required to
make a payment of any Excise Tax, the Accounting Firm shall determine the amount
of the  Underpayment  that  has  occurred  and any  such  Underpayment  shall be
promptly paid by Sonat to or for the benefit of Executive.

         (c)  Executive  shall  notify  Sonat  in  writing  of any  claim by the
Internal Revenue Service that, if successful, would require the payment by Sonat
of a Gross-Up Payment.  Such notification  shall be given as soon as practicable
but no later than ten  business  days after  Executive is informed in writing of
such claim and shall  apprise  Sonat of the nature of such claim and the date on
which such claim is  requested  to be paid.  Executive  shall not pay such claim
prior to the  expiration  of the 30-day  period  following  the date on which it
gives such notice to Sonat (or such shorter  period  ending on the date that any
payment of taxes with respect to such claim is due). If Sonat notifies Executive
in writing  prior to the  expiration  of such  period that it desires to contest
such claim, Executive shall:

                  (i)  give Sonat any information  reasonably requested by Sonat
         relating to such claim,

                  (ii) take such action in connection with contesting such claim
         as  Sonat  shall  reasonably  request  in  writing  from  time to time,
         including  without  limitation,  accepting  legal  representation  with
         respect to such claim by an attorney reasonably selected by Sonat,

                  (iii) cooperate with Sonat in good faith in order  effectively
         to contest such claim, and

                  (iv)  permit Sonat to participate in  any proceedings relating
         to such claim;

provided, however, that Sonat shall bear and pay directly all costs and expenses
(including  additional  interest and penalties) incurred in connection with such
contest and shall indemnify and hold Executive harmless,  on an after-tax basis,
for any  Excise  Tax or  federal,  state,  local,  employment  and  payroll  tax
(including  interest and penalties with respect  thereto) imposed as a result of
such representation and payment of costs and expenses. Without limitation on the
foregoing  provisions of this Section 6(c),  Sonat shall control all proceedings
taken in  connection  with such contest  and, at its sole option,  may pursue or
forgo any and all administrative appeals, proceedings,  hearings and conferences
with the taxing  authority in respect of such claim and may, at its sole option,
either  direct  Executive  to pay the tax  claimed  and sue for a  refund  or to
contest the claim in any permissible  manner,  and Executive agrees to prosecute
such contest to a determination before any administrative  tribunal,  in a court
of initial  jurisdiction  and in one or more  appellate  courts,  as Sonat shall
determine;  provided, however, that if Sonat directs Executive to pay such claim
and sue for a  refund,  Sonat  shall  advance  the  amount  of such  payment  to
Executive,  on an  interest-free  basis,  and shall indemnify and hold Executive
harmless on an after-tax basis,  from any Excise Tax or federal,  state,  local,
employment or payroll tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed  income with
respect to such advance;  and further provided that any extension of the statute
of  limitations  relating to payment of taxes for the taxable  year of Executive
with  respect  to which  such  contested  amount is claimed to be due is limited
solely to such contested  amount.  Furthermore,  Sonat's  control of the contest
shall be limited to issues  with  respect to which a Gross-Up  Payment  would be
payable hereunder,  and Executive shall be entitled to settle or contest, as the
case may be, any other issue raised by the Internal Revenue Service or any other
taxing authority.

         (d) If, after the receipt by  Executive of an amount  advanced by Sonat
pursuant to Section 6(c),  Executive becomes entitled to receive any refund with
respect to such claim,  Executive  shall (subject to Sonat's  complying with the
requirements  of Section  6(c))  promptly pay to Sonat the amount of such refund
(together  with any interest  paid or credited  thereon  after taxes  applicable
thereto).  If,  after the receipt by  Executive  of an amount  advanced by Sonat
pursuant to Section 6(c), a  determination  is made that Executive  shall not be
entitled  to any  refund  with  respect  to such claim and Sonat does not notify
Executive in writing of its intent to contest such denial of refund prior to the
expiration  of 30 days  after such  determination,  then such  advance  shall be
forgiven  and shall not be required to be repaid and the amount of such  advance
shall offset, to the extent thereof,  the amount of Gross-Up Payment required to
be paid.

         7. Term of Agreement.  This Agreement shall terminate on July 31, 1999;
provided,  however, that this Agreement shall automatically renew for successive
one-year  terms unless the Board of Directors  notifies  Executive in writing at
least 30 days  prior to a July 31  expiration  date  that it does not  desire to
renew the Agreement for an additional  term. This Agreement shall also terminate
if and when the Executive Compensation Committee determines that Executive is no
longer a key executive  for purposes of being a party to an executive  severance
agreement  with  Sonat and so  notifies  Executive  in  writing.  The  preceding
provisions  of this Section 7 to the contrary  notwithstanding,  this  Agreement
shall not  terminate  (i) within  three  years after a Change of Control or (ii)
during any period of time when Sonat has reason to believe that any third person
has begun a tender or exchange  offer,  circulated a proxy to  stockholders,  or
taken other steps or formulated plans to effect a Change of Control, such period
of time to end when, in the opinion of the Executive Compensation Committee, the
third person has abandoned or terminated his efforts or plans to effect a Change
of Control.

         8. Expenses.  Sonat shall pay or reimburse  Executive for all costs and
expenses,  including,  without  limitation,  court  costs and  attorneys'  fees,
incurred by Executive as a result of any claim, action or proceeding (including,
without  limitation,  a claim,  action or proceeding by Executive against Sonat)
arising out of, or challenging the validity or enforceability of, this Agreement
or any provision  hereof.  Sonat shall pay or reimburse  such costs and expenses
promptly  (and  within  30  days)  after  Executive  has  submitted   supporting
documentation.

         9.       Miscellaneous.

         (a)  Assignment.  No right,  benefit  or  interest  hereunder  shall be
subject to assignment,  anticipation,  alienation,  sale,  encumbrance,  charge,
pledge, hypothecation or set-off in respect of any claim, debt or obligation, or
to execution,  attachment,  levy or similar  process;  provided,  however,  that
Executive may assign any right, benefit or interest hereunder if such assignment
is  permitted  under the terms of any plan or policy  of  insurance  or  annuity
contract governing such right, benefit or interest.

         (b)  Construction  of  Agreement.  Nothing in this  Agreement  shall be
construed  to amend  any  provision  of any  plan or  policy  of  Sonat  and its
subsidiaries.  This  Agreement  is not,  and nothing  herein  shall be deemed to
create, a commitment of continued employment of Executive by Sonat or any of its
subsidiaries.

         (c) Amendment. This Agreement may not be amended, modified or cancelled
except by written agreement of the parties.

         (d) Waiver.  No provision of this  Agreement  may be waived except by a
writing signed by the party to be bound thereby.

                  Executive  may at any time or from  time to time  waive any or
all of the rights and benefits  provided for herein which have not been received
by Executive at the time of such waiver.  In addition,  prior to the last day of
the calendar year in which Executive's  Termination occurs,  Executive may waive
any or all rights and benefits  provided for herein which have been  received by
Executive; provided that prior to the end of such year Executive repays to Sonat
(or, if the benefit was received  from an employee  benefit plan trust,  to such
trust) the amount of the benefit received  together with interest thereon at the
minimum rate required to avoid imputed income.  Any waiver of benefits  pursuant
to this paragraph shall be irrevocable.  If Executive  waives a right or benefit
provided  for herein  and such  waiver is  determined  by the  Internal  Revenue
Service not to be  effective,  Sonat shall  indemnify  Executive for any federal
income and excise taxes Executive incurs as a result of that  determination,  so
as to put Executive in the position  Executive would have been in had the waiver
been given effect.

         (e)  Severability.  In the event that any  provision or portion of this
Agreement shall be determined to be invalid or unenforceable for any reason, the
remaining  provisions of this Agreement shall remain in full force and effect to
the fullest extent permitted by law.

         (f)  Successors.  This Agreement shall be binding upon and inure to the
benefit of Executive and  Executive's  personal  representative  and heirs,  and
Sonat and any successor  organization  or  organizations  which shall succeed to
substantially  all of the business  and  property of Sonat,  whether by means of
merger,  consolidation,  acquisition of substantially all of the assets of Sonat
or otherwise, including by operation of law.

         (g) Taxes. Any payment or delivery  required under this Agreement shall
be subject to all  requirements  of the law with regard to withholding of taxes,
filing,  making of reports and the like, and Sonat shall use its best efforts to
satisfy promptly all such requirements.

         (h) Governing  Law. This  Agreement  shall be governed and construed in
accordance with the laws of the State of Delaware.

         (i) Entire  Agreement.  This Agreement sets forth the entire  agreement
and  understanding  of the parties  hereto with  respect to the matters  covered
hereby,  and  incorporates  into one document any previous  severance  agreement
executed by the parties and all amendments thereto as of the date hereof.

         IN WITNESS  WHEREOF,  the parties have executed this  Agreement as July
23, 1998.


                                       SONAT INC.



                              By:
                                       Vice President - Human Resources and
                                       Secretary




                                       Ronald L. Kuehn, Jr.



                                                                    EXHIBIT 10.6

         EXECUTIVE  SEVERANCE  AGREEMENT,  dated as of July  23,  1998,  by  and
between  Sonat  Inc.,  a  Delaware corporation ("Sonat"),  and Thomas W. Barker,
Jr. ("Executive").

         WHEREAS, the Executive Compensation Committee of the Board of Directors
of Sonat has  recommended,  and the Board of Directors has approved,  that Sonat
enter into  severance  agreements  with key executives who are from time to time
designated by the Executive Compensation Committee;

         WHEREAS,  should  Sonat become  subject to any  proposed or  threatened
Change of Control (as hereinafter  defined),  the Board of Directors believes it
imperative  that Sonat and the Board of Directors be able to rely upon Executive
to continue in Executive's position,  and that Sonat be able to receive and rely
upon Executive's advice, if requested, as to the best interests of Sonat and its
stockholders  without concern that Executive might be distracted by the personal
uncertainties and risks created by such a proposal or threat;

         WHEREAS,  should  Sonat  receive  any such  proposals,  in  addition to
Executive's  regular  duties,  Executive  may be  called  upon to  assist in the
assessment of such proposals, to advise management and the Board of Directors as
to  whether  such  proposals  would be in the best  interests  of Sonat  and its
stockholders,  and to take such other  actions as the Board of  Directors  might
determine to be appropriate;

         WHEREAS,  Executive is a key executive and, pursuant to action taken by
the Executive Compensation Committee and the Board of Directors,  has previously
entered into a severance agreement with Sonat; and

         WHEREAS,  the  Executive   Compensation  Committee  and  the  Board  of
Directors have approved certain revisions to such severance agreement, Executive
agrees to such  revisions,  and  Executive and Sonat desire to amend and restate
such severance agreement in order to consolidate the terms thereof into a single
document;

         NOW, THEREFORE, Sonat and Executive agree as follows:

         1. Services During Certain Events. In the event a third person begins a
tender or exchange  offer,  circulates a proxy to  stockholders,  or takes other
steps to effect a Change of Control,  Executive agrees not to voluntarily  leave
the employ of Sonat or its subsidiaries, and to render the services contemplated
in the  recitals to this  Agreement,  until the third  person has  abandoned  or
terminated  his  efforts  to  effect a Change  of  Control  or until a Change of
Control has occurred.

         2.  Termination  Following  Change of  Control.  Except as  provided in
Section 4 hereof,  Sonat will provide or cause to be provided to  Executive  the
rights and benefits  described in Section 3 hereof in the event that Executive's
employment is terminated:

                  (a) at any time  within  three  years  following  a Change  of
         Control by Sonat or its subsidiaries for reasons other than for "cause"
         (as such  term is  defined  in  Section 4  hereof)  or other  than as a
         consequence of Executive's death, permanent disability or retirement at
         or  after  the  normal   retirement  date  as  provided  under  Sonat's
         Retirement Plan as in effect  immediately  preceding such date ("Normal
         Retirement Date");

                  (b) at any time  within  three  years  following  a Change  of
         Control by Executive  following the  occurrence of any of the following
         events without Executive's written consent:

                           (i) the  assignment  of  Executive  to any  duties or
                  responsibilities   that  are  inconsistent   with  Executive's
                  position,  duties,   responsibilities  or  status  immediately
                  preceding  such  Change of Control,  or a change in  reporting
                  responsibilities or titles in effect at such time resulting in
                  a reduction of Executive's responsibilities or position;

                           (ii)  the  reduction  of  Executive's  annual  salary
                  (including any deferred portions thereof), annual or long-term
                  cash or stock  bonus  opportunities,  or level of  benefits or
                  supplemental compensation; or

                           (iii)  the   transfer  of  Executive  to  a  location
                  requiring  a change in  Executive's  residence  or a  material
                  increase  in  the  amount  of  travel  normally   required  of
                  Executive in connection with Executive's employment; or

                  (c) by  Executive  for any reason  during  the  30-day  period
         immediately  following the first  anniversary of the date of the Change
         of Control.

                  For  purposes of this  Agreement,  "Change of  Control"  shall
mean:

                  A. The acquisition by any individual,  entity or group (within
the meaning of Section  13(d)(3) or 14(d)(2) of the  Securities  Exchange Act of
1934,  as amended (the  "Exchange  Act")) (a "Person") of  beneficial  ownership
(within the meaning of Rule 13(d)-3  promulgated  under the Exchange Act) of 20%
or more of either (i) the then outstanding  shares of common stock of Sonat (the
"Outstanding  Common  Stock")  or (ii)  the  combined  voting  power of the then
outstanding  voting  securities  of  Sonat  entitled  to vote  generally  in the
election of directors (the "Outstanding Voting Securities");  provided, however,
that for purposes of this  subsection  A, the following  acquisitions  shall not
constitute a Change of Control:  (i) any acquisition  directly from Sonat,  (ii)
any acquisition by Sonat, (iii) any acquisition by any employee benefit plan (or
related trust) sponsored or maintained by Sonat or any corporation controlled by
Sonat or (iv) any acquisition by any corporation pursuant to a transaction which
complies with clauses (i), (ii) and (iii) of subsection C; or

                  B.  Individuals  who, as of the date  hereof,  constitute  the
Board of Directors (the "Incumbent Board") cease for any reason to constitute at
least  a  majority  of the  Board  of  Directors;  provided,  however  that  any
individual becoming a director subsequent to the date hereof whose election,  or
nomination  for election by Sonat's  shareholders,  was approved by a vote of at
least a majority of the directors then  comprising the Incumbent  Board shall be
considered as though such individual were a member of the Incumbent  Board,  but
excluding,  for this purpose,  any such individual  whose initial  assumption of
office  occurs  as a result of an actual or  threatened  election  contest  with
respect to the election or removal of  directors  or other actual or  threatened
solicitation  of proxies or consents by or on behalf of a Person  other than the
Board of Directors; or

                  C. Consummation of a  reorganization,  merger or consolidation
or sale or other  disposition of all or substantially all of the assets of Sonat
(a  "Business  Combination"),  in each case,  unless,  following  such  Business
Combination,  (i) all or  substantially  all of the individuals and entities who
were the beneficial  owners,  respectively,  of the Outstanding Common Stock and
Outstanding  Voting Securities  immediately  prior to such Business  Combination
beneficially own, directly or indirectly,  more than 50% of,  respectively,  the
then  outstanding  shares of common stock and the  combined  voting power of the
then outstanding voting securities entitled to vote generally in the election of
directors,  as the case may be, of the corporation  resulting from such Business
Combination (including,  without limitation,  a corporation which as a result of
such transaction owns Sonat or all or substantially all of Sonat's assets either
directly  or  through  one or  more  subsidiaries)  in  substantially  the  same
proportions as their ownership,  immediately prior to such Business Combination,
of the Outstanding Common Stock and Outstanding  Voting Securities,  as the case
may be, (ii) no Person  (excluding any corporation  resulting from such Business
Combination  or any employee  benefit  plan (or related  trust) of Sonat or such
corporation  resulting  from  such  Business  Combination)   beneficially  owns,
directly  or  indirectly,  20% or more of,  respectively,  the then  outstanding
shares  of  common  stock  of  the  corporation  resulting  from  such  Business
Combination  or the  combined  voting  power  of  the  then  outstanding  voting
securities of such corporation  except to the extent that such ownership existed
prior to the Business  Combination  and (iii) at least a majority of the members
of the board of  directors  of the  corporation  resulting  from  such  Business
Combination  were members of the Incumbent Board at the time of the execution of
the initial agreement, or of the action of the Board of Directors, providing for
such Business Combination.

         3.  Rights  and  Benefits  upon  Termination.   In  the  event  of  the
termination of Executive's  employment under any of the  circumstances set forth
in  Section 2 hereof  ("Termination"),  Sonat  agrees to  provide or cause to be
provided to Executive the following rights and benefits:

                  (a)  Lump  Sum  Payment  at  Termination.  Executive  shall be
         entitled to receive within 30 days of Termination a lump-sum payment in
         cash in the amount of three times Executive's Earnings (as such term is
         defined in this Section  3(a));  provided,  however,  that if there are
         fewer  than  36  months  remaining  from  the  date of  Termination  to
         Executive's  Normal Retirement Date, the amount calculated  pursuant to
         this  paragraph  will  be  reduced  by  multiplying  such  amount  by a
         fraction, the numerator of which is the number of months (including any
         fraction of a month) so remaining to Executive's Normal Retirement Date
         and the denominator of which is 36.

                           For purposes of this Agreement, "Earnings" shall mean
         the sum of (1)  Executive's  Annual  Base Pay (as defined  below),  (2)
         Executive's  Recent Cash Bonus (as defined below),  and (3) Executive's
         Recent Long-Term Compensation (as defined below).

                           "Annual  Base Pay" shall mean the  greater of (1) the
         annualized  amount of Executive's rate of base pay (as shown in Sonat's
         payroll records)  immediately before the Change of Control, and (2) the
         annualized  amount of Executive's rate of base pay (as shown in Sonat's
         payroll records) immediately before the date of Termination.

                           "Recent   Cash  Bonus"  shall  mean  the  product  of
         Executive's Annual Base Pay multiplied by the greater of:

                                            (1)  the  quotient   determined   by
                                    dividing (a) the sum of the amounts  payable
                                    to Executive upon the occurrence of a Change
                                    of  Control   pursuant  to  Section  2.6  of
                                    Sonat's  Performance Award Plan, Section 2.6
                                    of Sonat's Cash Bonus Plan,  and Section 2.6
                                    of Sonat's  Performance Award and Cash Bonus
                                    Plan (regardless of whether such amounts are
                                    paid in a lump sum or in  installments),  by
                                    (b) the  annualized  amount  of  Executive's
                                    rate  of  base  pay  (as  shown  in  Sonat's
                                    payroll  records)   immediately  before  the
                                    Change of Control; and

                                            (2) the highest quotient determined,
                                    for the calendar year in which the Change of
                                    Control  occurs  and  for  each  of the  two
                                    preceding  calendar  years,  by dividing (a)
                                    the sum of the  bonuses  paid  to  Executive
                                    under the  Performance  Award Plan, the Cash
                                    Bonus Plan,  and the  Performance  Award and
                                    Cash  Bonus Plan  during the first  calendar
                                    quarter of such calendar year (including for
                                    this purpose any amount receipt of which was
                                    deferred by the Executive

                                                     Compensation      Committee
                                    pursuant to the terms of such  Plans,  or by
                                    Executive  pursuant  to the terms of Sonat's
                                    Deferred  Compensation  Plan),  by  (b)  the
                                    annualized  amount  of  Executive's  rate of
                                    base  pay  (as  shown  in  Sonat's   payroll
                                    records)  at  the  time  of  such   payment.
                                    Notwithstanding  the  foregoing,  if at  the
                                    time of the  Change of  Control  the  amount
                                    paid to Executive  under clause (1) above is
                                    with   respect   to  a   bonus   opportunity
                                    established for the preceding  calendar year
                                    (or  a  portion   thereof),   the  quotients
                                    calculated pursuant to this clause (2) shall
                                    be determined for each of the three calendar
                                    years before the calendar  year in which the
                                    Change of Control occurs.

                  "Recent  Long-Term  Compensation"  shall  mean the  product of
Executive's  Annual  Base  Pay  multiplied  by  the  average  of  the  quotients
determined,  for each of the three  calendar years before the date of the Change
of Control,  by dividing (a) the Grant Value (as defined  below) for the regular
annual  grant of stock  options  and/or  restricted  stock  made  under  Sonat's
Executive Award Plan during the fourth calendar quarter of such calendar year by
(b) the annualized  amount of Executive's  rate of base pay (as shown in Sonat's
payroll records) on the date of such grant. Grant Value shall mean, with respect
to any such annual grant during any fourth calendar quarter,  the sum of (1) the
product of the number of stock  options  granted to Executive  multiplied by the
value of each such stock option at the date of grant (as  determined or approved
by the  Executive  Compensation  Committee  at the date of grant),  plus (2) the
product  of the  number of shares  of  restricted  stock  granted  to  Executive
multiplied by the value of a share of restricted  stock at the date of grant (as
determined  or approved by the Executive  Compensation  Committee at the date of
grant).  Notwithstanding  the foregoing,  if the Change of Control occurs in the
fourth calendar quarter of a calendar year and after the regular annual grant of
stock options and/or restricted stock for such year, the quotients calculated as
described  above  shall be  determined  for such  calendar  year and for the two
preceding  calendar years.  If the quotient  determined for any calendar year is
zero, such quotient shall be disregarded  (and no additional  quotients shall be
calculated in substitution therefor).

                  (b)  Retirement  Benefits.  If at  the  date  of  Termination,
         Executive  is not  otherwise  entitled  to receive an early  retirement
         benefit under the terms of a qualified defined benefit  retirement plan
         of Sonat or its subsidiaries,  Sonat shall pay in cash to Executive, in
         the form of a cash  lump sum (a  "Severance  Retirement  Benefit"),  an
         amount  equal to the  Actuarial  Equivalent  (as defined  below) of the
         excess,  if any, of (1) the monthly benefit  calculated under the early
         retirement  provisions of the Retirement Plan (as in effect immediately
         prior to the Change of Control),  using the early retirement  reduction
         factors  applicable as of the later of age 55 or Executive's actual age
         at the date of  Termination,  and (2) the  monthly  benefit  payable to
         Executive  under  the  Retirement  Plan  (as in  effect  on the date of
         Executive's  Termination),  assuming  the  following  for  purposes  of
         clauses (1) and (2): (A) the benefit is payable in the form of a single
         life annuity as of the later of the date  Executive  attains age 55 and
         the  date of  Termination;  (B) the  benefit  is  calculated  based  on
         Executive's  actual service and actual earnings  history at the date of
         Termination;  (C) Executive is fully vested in the benefit; and (D) the
         benefit is calculated under the assumption that Sections 401(a)(17) and
         415 of the Internal Revenue Code of 1986, as amended (the "Code"),  are
         nonexistent  and the  provisions of the Retirement  Plan  incorporating
         such Code Sections are  inoperative.  The  determination of Executive's
         Severance  Retirement  Benefit  shall  not  include  the  value  of any
         benefits under the "cash balance"  portion of the Retirement  Plan. The
         Severance  Retirement Benefit shall be paid as soon as practicable (and
         within  30  days)  after  the date of  Termination,  and  shall  not be
         affected  by the  settlement  option  or  date of  commencement  of any
         benefits   actually  payable  under  the  Retirement  Plan  or  Sonat's
         Supplemental Benefit Plan.

                  (c) Survivors' Benefits. If Executive is entitled to receive a
         Severance  Retirement  Benefit  under  Section  3(b) and on the date of
         Termination  Executive  either (1) has an Eligible Spouse (as such term
         is defined in the Retirement Plan as in effect immediately prior to the
         Change of Control,  and determined as if Executive had died on the date
         of  Termination),  or (2) does not have an Eligible  Spouse (as defined
         above)  but does have one or more  Eligible  Children  (as such term is
         defined in the Retirement  Plan as in effect  immediately  prior to the
         Change of Control,  and determined as if Executive had died on the date
         of  Termination),  Sonat shall pay to Executive,  in the form of a cash
         lump sum (the "Severance Survivors'  Benefit"),  an amount equal to the
         Actuarial  Equivalent of the monthly survivors' benefit payable to such
         Eligible  Spouse or  Eligible  Children  (as the case may be) under the
         Retirement  Plan  (as in  effect  immediately  prior to the  Change  of
         Control) with respect to Executive if  Executive's  retirement  benefit
         were  calculated  under the early  retirement  provisions of such plan,
         using the early retirement  benefit reduction factors  applicable as of
         the  later  of  age  55 or  Executive's  actual  age  at  the  date  of
         Termination,  and assuming (A) the retirement  benefit is payable as of
         the  later  of the  date  Executive  attains  age 55 and  the  date  of
         Termination;   (B)  the  retirement  benefit  is  calculated  based  on
         Executive's  actual service and actual earnings  history at the date of
         Termination;  (C) Executive is fully vested in the retirement  benefit;
         and (D) the retirement  benefit and  survivors'  benefit are calculated
         under  the  assumption  that  Code  Sections  401(a)(17)  and  415  are
         nonexistent  and Section 7.10 and the provisions of the Retirement Plan
         incorporating  the  limitations  contained  in such Code  Sections  are
         inoperative.  The  determination  of Executive's  Severance  Survivors'
         Benefit  shall not  include the value of any  benefits  under the "cash
         balance" portion of the Retirement Plan.

         The Severance  Survivors'  Benefit shall be paid as soon as practicable
         (and  within 30 days)  after the date of  Termination  and shall not be
         affected  by any  settlement  option  or  date of  commencement  of any
         benefits actually payable under the Retirement Plan or the Supplemental
         Benefit Plan.

                  (d)  Insurance  and  Other  Special  Benefits.  To the  extent
         Executive  is  eligible  thereunder,  Executive  shall  continue  to be
         covered by the life and dependent  life  insurance,  medical and dental
         insurance, and accident and disability insurance plans of Sonat and its
         subsidiaries  or any successor plan or program in effect at Termination
         for  employees in the same class or category as  Executive,  subject to
         the  terms  of  such  plans  and to  Executive's  making  any  required
         contributions thereto. In the event Executive is ineligible to continue
         to be so covered  under the terms of any such  benefit plan or program,
         or in the event  Executive is eligible but the benefits  applicable  to
         Executive are not substantially  equivalent to the benefits  applicable
         to Executive immediately prior to Termination, then, for a period of 36
         months following  Termination (or until  Executive's  Normal Retirement
         Date,  whichever is sooner),  Sonat shall  provide  such  substantially
         equivalent benefits, or such additional benefits as may be necessary to
         make the benefits applicable to Executive  substantially  equivalent to
         those in effect before  Termination,  through other sources;  provided,
         however,  that if during such period  Executive  should  enter into the
         employ of another company or firm which provides  substantially similar
         benefit coverage,  Executive's  participation in the comparable benefit
         provided by Sonat either  directly or through such other  sources shall
         cease.  Nothing  contained in this paragraph shall be deemed to require
         or permit termination or restriction of Executive's  coverage under any
         plan or program of Sonat or any of its  subsidiaries  or any  successor
         plan or program  thereto to which Executive is entitled under the terms
         of  such  plan or  program,  whether  at the end of the  aforementioned
         36-month  period or at any other time.  Executive  shall be entitled to
         continuation  ("COBRA")  coverage  under  Code  Section  4980B upon the
         termination  of the  coverage  provided  under this Section 3(d) to the
         same  extent  as if such  coverage  had not  been  provided.  Upon  the
         occurrence  of  both  (1)  the  termination  of  the  medical  coverage
         (including any COBRA coverage elected by Executive) provided under this
         Section 3(d), and (2) Executive's attainment of age 55, Executive shall
         be eligible  for such  retiree  medical  coverage  as may be  available
         generally to early or normal retirees of Sonat, or to former  employees
         in the same class or  category  as  Executive,  subject to the terms of
         such  coverage and to  Executive's  making any  required  contributions
         thereto.

                  (e) Relocation  Assistance.  Should  Executive move his or her
         residence in order to pursue other business  opportunities within three
         years  of  the  date  of  Termination  (or  until  Executive's   Normal
         Retirement Date, whichever is sooner),  Sonat shall reimburse Executive
         for any expenses  incurred in that relocation  (including taxes payable
         on the  reimbursement)  which are not  reimbursed by another  employer;
         provided,   however,   that   Executive   shall  be  entitled  to  such
         reimbursement with respect to only one such relocation, it being agreed
         that in the event of more than one such relocation,  Executive shall be
         entitled to specify the relocation for which reimbursement hereunder is
         to be made.  Benefits under this provision will include the assistance,
         at no  cost  to  Executive,  in  selling  Executive's  home  and  other
         assistance  which was  customarily  provided to executives  transferred
         within Sonat or between Sonat and its subsidiaries  prior to the Change
         of Control.

                  (f) Other Benefit Plans. The specific arrangements referred to
         in this Section 3 are not intended to exclude Executive's participation
         in other benefit plans in which  Executive  currently  participates  or
         which are  available to executive  personnel  generally in the class or
         category of Executive or to preclude other  compensation or benefits as
         may be authorized by the Board of Directors from time to time.

                  (g) Duty to  Mitigate.  Executive's  entitlement  to  benefits
         hereunder  shall not be  governed  by any duty to  mitigate  damages by
         seeking  further  employment  nor  offset  by  any  compensation  which
         Executive may receive from future employment.

                  (h) Payment Obligations Absolute. Sonat's obligation to pay or
         cause to be paid to Executive the benefits and to make the arrangements
         provided in this  Section 3 shall be  absolute  and  unconditional  and
         shall  not  be  affected  by  any  circumstances,   including,  without
         limitation,  any  setoff,  counterclaim,  recoupment,  defense or other
         right,  which Sonat may have  against  Executive  or anyone  else.  All
         amounts  payable  by or on  behalf  of  Sonat  hereunder  shall be paid
         without  notice or demand.  Each and every payment made hereunder by or
         on behalf of Sonat shall be final and Sonat and its subsidiaries  shall
         not, for any reason whatsoever, seek to recover all or any part of such
         payment from Executive or from whomever shall be entitled thereto.

                  (i) Actuarial Equivalent.  "Actuarial Equivalent" shall mean a
         benefit actuarially equal in value to the value of a given benefit in a
         given form or schedule, based upon (1) the 1983 Group Annuity Mortality
         Table  (or,  if  different,  the  mortality  table  or  tables  used to
         calculate  Actuarial  Equivalents  under the Retirement  Plan as of the
         date on which an Actuarial  Equivalent is being  determined  under this
         Agreement) and (2) an interest rate equal to the yield on new 7-12 year
         AA-rated general  obligation  tax-exempt bonds as determined by Merrill
         Lynch & Co.  (or its  affiliates)  and  published  in The  Wall  Street
         Journal  (or  other   financial   publication)   on  the  business  day
         immediately preceding the date of Executive's  Termination (or, if such
         yield is not so  determined  and published on such business day, on the
         most  immediately  preceding  day on which such yield was so determined
         and published);  provided,  however, that if such yield has not been so
         determined  and  published   within  90  days  prior  to  the  date  of
         Executive's  Termination,  the  interest  rate  shall  be the  yield on
         substantially similar securities on the business day preceding the date
         of Executive's  Termination as determined by AmSouth Bank N.A. upon the
         request of either Sonat or Executive.

                  The  Severance   Survivors'  Benefit  shall  be  valued  as  a
         reversionary  annuity  commencing  upon  the  death of  Executive.  For
         purposes of calculating the Severance  Survivors' Benefit, (1) it shall
         be assumed that Executive, Executive's Eligible Spouse, and Executive's
         Eligible  Children  do not die before  the later of the date  Executive
         attains  age 55 and the  date of  Executive's  Termination,  and (2) if
         Executive has Eligible Children (but not an Eligible Spouse),  it shall
         be assumed that each Eligible Child remains an Eligible Child until the
         date such Eligible  Child  attains age 25 and that such Eligible  Child
         does not die before such date.

         4.  Conditions  to the  Obligations  of  Sonat.  Sonat  shall  have  no
obligation  to  provide  or cause to be  provided  to  Executive  the rights and
benefits  described in Section 3 hereof if either of the following  events shall
occur:

                  (a) Termination  for Cause.  Sonat or its  subsidiaries  shall
         terminate  Executive's  employment  for  "cause".  For purposes of this
         Agreement, termination of employment for "cause" shall mean termination
         solely for dishonesty,  conviction of a felony, or willful unauthorized
         disclosure of confidential information of Sonat.

                  (b)  Resignation as Director.  Executive  shall not,  promptly
         after Termination and upon receiving a written request to do so, resign
         as a director  and/or officer of each subsidiary and affiliate of Sonat
         of which Executive is then serving as a director and/or officer.

         5.       Confidentiality; Non-Solicitation; Cooperation.

         (a)  Confidentiality.  Executive  agrees  that at all  times  following
Termination,  Executive  will not,  without the prior written  consent of Sonat,
disclose to any person,  firm or  corporation  any  confidential  information of
Sonat or its subsidiaries which is now known to Executive or which hereafter may
become known to Executive as a result of  Executive's  employment or association
with Sonat and which could be helpful to a competitor, unless such disclosure is
required under the terms of a valid and effective  subpoena or order issued by a
court or  governmental  body;  provided,  however,  that the foregoing shall not
apply to confidential  information which becomes publicly  disseminated by means
other than a breach of this Agreement.

         (b) Non-Solicitation. Executive agrees that for a period of three years
following the date of Termination (or until Executive's  Normal Retirement Date,
whichever is sooner)  Executive will not induce,  either directly or indirectly,
any employee of senior to manager level of Sonat or any of its  subsidiaries  to
terminate his or her employment.

         (c)  Cooperation.   Executive  agrees  that,  at  all  times  following
Termination,  Executive will furnish such information and render such assistance
and cooperation as may reasonably be requested in connection with any litigation
or legal proceedings concerning Sonat or any of its subsidiaries (other than any
legal proceedings  concerning Executive's  employment).  In connection with such
cooperation, Sonat will pay or reimburse Executive for reasonable expenses.

         (d) Remedies for Breach.  It is recognized that damages in the event of
breach of this Section 5 by Executive would be difficult, if not impossible,  to
ascertain,  and it is  therefore  agreed that Sonat,  in addition to and without
limiting  any  other  remedy or right it may  have,  shall  have the right to an
injunction  or other  equitable  relief in any court of competent  jurisdiction,
enjoining  any such breach,  and  Executive  hereby  waives any and all defenses
Executive  may have on the ground of lack of  jurisdiction  or competence of the
court to grant such an injunction or other  equitable  relief.  The existence of
this right shall not preclude  Sonat from pursuing any other rights and remedies
at law or in equity which Sonat may have.

         6. Certain Additional Payments by Sonat. (a) Anything in this Agreement
to the contrary  notwithstanding  and except as set forth below, in the event it
shall be  determined  that any  payment or  distribution  by Sonat to or for the
benefit of  Executive,  or any benefit,  arrangement  regarding  the exercise or
vesting of options,  restricted  stock,  or other  securities of Sonat, or other
plan,  agreement or arrangement  regarding a change of control of Sonat (whether
determined pursuant to the terms of this Agreement or otherwise,  but determined
without  regard to any additional  payments  required under this Section 6) (any
such payment,  distribution,  benefit,  arrangement,  plan,  or agreement  being
referred  to as a  "Payment")  would be subject  to the  excise  tax  imposed by
Section 4999 of the Code or any interest or penalties  are incurred by Executive
with  respect  to such  excise  tax (such  excise  tax,  together  with any such
interest and penalties,  are hereinafter collectively referred to as the "Excise
Tax"),  then  Executive  shall be entitled to receive an  additional  payment (a
"Gross-Up  Payment")  in an amount such that after  payment by  Executive of all
federal,  state, local,  employment and payroll taxes (including any interest or
penalties imposed with respect to such taxes),  including,  without  limitation,
any federal,  state,  local,  employment and payroll taxes (and any interest and
penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up
Payment, Executive retains an amount of the Gross-Up Payment equal to the Excise
Tax imposed upon the Payments.  Notwithstanding the foregoing provisions of this
Section 6(a), if it shall be determined that Executive is entitled to a Gross-Up
Payment,  but that  Executive,  after  taking into  account the Payments and the
Gross-Up Payment,  would not receive a net after-tax benefit of at least $50,000
(taking into account both federal,  state,  local,  employment and payroll taxes
and any Excise  Tax) as  compared to the net  after-tax  proceeds  to  Executive
resulting  from an  elimination  of the Gross-Up  Payment and a reduction of the
Payments,  in the aggregate,  to an amount (the "Reduced  Amount") such that the
receipt of  Payments  would not give rise to any Excise  Tax,  then no  Gross-Up
Payment shall be made to Executive and the Payments, in the aggregate,  shall be
reduced to the Reduced Amount.

         (b)  Subject to the  provisions  of Section  6(c),  all  determinations
required to be made under this Section 6, including  whether and when a Gross-Up
Payment is required and the amount of such Gross-Up  Payment and the assumptions
to be utilized in arriving at such determination, shall be made by Ernst & Young
LLP or such other  certified  public  accounting  firm as may be  designated  by
Executive  (the  "Accounting  Firm"),  which shall provide  detailed  supporting
calculations  both to Sonat and Executive within 15 business days of the receipt
of notice from  Executive  that there has been a Payment or such earlier time as
is  requested  by Sonat.  In the event  that the  Accounting  Firm is serving as
accountant or auditor for the individual,  entity or group effecting a Change of
Control,  Executive shall appoint another nationally  recognized accounting firm
to make the determinations  required hereunder (which accounting firm shall then
be referred to as the Accounting Firm  hereunder).  All fees and expenses of the
Accounting  Firm shall be borne solely by Sonat.  Any Gross-Up  Payment shall be
paid by Sonat to  Executive  within five days of the  receipt of the  Accounting
Firm's determination.  Any determination by the Accounting Firm shall be binding
upon Sonat and Executive.  As a result of the  uncertainty in the application of
Section  4999  of the  Code  at the  time of the  initial  determination  by the
Accounting Firm hereunder,  it is possible that Gross-Up Payments which will not
have been made by Sonat should have been made ("Underpayment"),  consistent with
the calculations required to be made hereunder. In the event that Sonat exhausts
its remedies  pursuant to Section 6(c) and  Executive  thereafter is required to
make a payment of any Excise Tax, the Accounting Firm shall determine the amount
of the  Underpayment  that  has  occurred  and any  such  Underpayment  shall be
promptly paid by Sonat to or for the benefit of Executive.

         (c)  Executive  shall  notify  Sonat  in  writing  of any  claim by the
Internal Revenue Service that, if successful, would require the payment by Sonat
of a Gross-Up Payment.  Such notification  shall be given as soon as practicable
but no later than ten  business  days after  Executive is informed in writing of
such claim and shall  apprise  Sonat of the nature of such claim and the date on
which such claim is  requested  to be paid.  Executive  shall not pay such claim
prior to the  expiration  of the 30-day  period  following  the date on which it
gives such notice to Sonat (or such shorter  period  ending on the date that any
payment of taxes with respect to such claim is due). If Sonat notifies Executive
in writing  prior to the  expiration  of such  period that it desires to contest
such claim, Executive shall:

                  (i)  give Sonat any information reasonably requested  by Sonat
         relating to such claim,

                  (ii) take such action in connection with contesting such claim
         as  Sonat  shall  reasonably  request  in  writing  from  time to time,
         including  without  limitation,  accepting  legal  representation  with
         respect to such claim by an attorney reasonably selected by Sonat,

                  (iii) cooperate with Sonat in good faith in order  effectively
         to contest such claim, and

                  (iv)  permit Sonat to participate in  any proceedings relating
         to such claim;

provided, however, that Sonat shall bear and pay directly all costs and expenses
(including  additional  interest and penalties) incurred in connection with such
contest and shall indemnify and hold Executive harmless,  on an after-tax basis,
for any  Excise  Tax or  federal,  state,  local,  employment  and  payroll  tax
(including  interest and penalties with respect  thereto) imposed as a result of
such representation and payment of costs and expenses. Without limitation on the
foregoing  provisions of this Section 6(c),  Sonat shall control all proceedings
taken in  connection  with such contest  and, at its sole option,  may pursue or
forgo any and all administrative appeals, proceedings,  hearings and conferences
with the taxing  authority in respect of such claim and may, at its sole option,
either  direct  Executive  to pay the tax  claimed  and sue for a  refund  or to
contest the claim in any permissible  manner,  and Executive agrees to prosecute
such contest to a determination before any administrative  tribunal,  in a court
of initial  jurisdiction  and in one or more  appellate  courts,  as Sonat shall
determine;  provided, however, that if Sonat directs Executive to pay such claim
and sue for a  refund,  Sonat  shall  advance  the  amount  of such  payment  to
Executive,  on an  interest-free  basis,  and shall indemnify and hold Executive
harmless on an after-tax basis,  from any Excise Tax or federal,  state,  local,
employment or payroll tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed  income with
respect to such advance;  and further provided that any extension of the statute
of  limitations  relating to payment of taxes for the taxable  year of Executive
with  respect  to which  such  contested  amount is claimed to be due is limited
solely to such contested  amount.  Furthermore,  Sonat's  control of the contest
shall be limited to issues  with  respect to which a Gross-Up  Payment  would be
payable hereunder,  and Executive shall be entitled to settle or contest, as the
case may be, any other issue raised by the Internal Revenue Service or any other
taxing authority.

         (d) If, after the receipt by  Executive of an amount  advanced by Sonat
pursuant to Section 6(c),  Executive becomes entitled to receive any refund with
respect to such claim,  Executive  shall (subject to Sonat's  complying with the
requirements  of Section  6(c))  promptly pay to Sonat the amount of such refund
(together  with any interest  paid or credited  thereon  after taxes  applicable
thereto).  If,  after the receipt by  Executive  of an amount  advanced by Sonat
pursuant to Section 6(c), a  determination  is made that Executive  shall not be
entitled  to any  refund  with  respect  to such claim and Sonat does not notify
Executive in writing of its intent to contest such denial of refund prior to the
expiration  of 30 days  after such  determination,  then such  advance  shall be
forgiven  and shall not be required to be repaid and the amount of such  advance
shall offset, to the extent thereof,  the amount of Gross-Up Payment required to
be paid.

         7. Term of Agreement.  This Agreement shall terminate on July 31, 1999;
provided,  however, that this Agreement shall automatically renew for successive
one-year  terms unless the Board of Directors  notifies  Executive in writing at
least 30 days  prior to a July 31  expiration  date  that it does not  desire to
renew the Agreement for an additional  term. This Agreement shall also terminate
if and when the Executive Compensation Committee determines that Executive is no
longer a key executive  for purposes of being a party to an executive  severance
agreement  with  Sonat and so  notifies  Executive  in  writing.  The  preceding
provisions  of this Section 7 to the contrary  notwithstanding,  this  Agreement
shall not  terminate  (i) within  three  years after a Change of Control or (ii)
during any period of time when Sonat has reason to believe that any third person
has begun a tender or exchange  offer,  circulated a proxy to  stockholders,  or
taken other steps or formulated plans to effect a Change of Control, such period
of time to end when, in the opinion of the Executive Compensation Committee, the
third person has abandoned or terminated his efforts or plans to effect a Change
of Control.

         8. Expenses.  Sonat shall pay or reimburse  Executive for all costs and
expenses,  including,  without  limitation,  court  costs and  attorneys'  fees,
incurred by Executive as a result of any claim, action or proceeding (including,
without  limitation,  a claim,  action or proceeding by Executive against Sonat)
arising out of, or challenging the validity or enforceability of, this Agreement
or any provision  hereof.  Sonat shall pay or reimburse  such costs and expenses
promptly  (and  within  30  days)  after  Executive  has  submitted   supporting
documentation.

         9.       Miscellaneous.

         (a)  Assignment.  No right,  benefit  or  interest  hereunder  shall be
subject to assignment,  anticipation,  alienation,  sale,  encumbrance,  charge,
pledge, hypothecation or set-off in respect of any claim, debt or obligation, or
to execution,  attachment,  levy or similar  process;  provided,  however,  that
Executive may assign any right, benefit or interest hereunder if such assignment
is  permitted  under the terms of any plan or policy  of  insurance  or  annuity
contract governing such right, benefit or interest.

         (b)  Construction  of  Agreement.  Nothing in this  Agreement  shall be
construed  to amend  any  provision  of any  plan or  policy  of  Sonat  and its
subsidiaries.  This  Agreement  is not,  and nothing  herein  shall be deemed to
create, a commitment of continued employment of Executive by Sonat or any of its
subsidiaries.

         (c) Amendment. This Agreement may not be amended, modified or cancelled
except by written agreement of the parties.

         (d) Waiver.  No provision of this  Agreement  may be waived except by a
writing signed by the party to be bound thereby.

                  Executive  may at any time or from  time to time  waive any or
all of the rights and benefits  provided for herein which have not been received
by Executive at the time of such waiver.  In addition,  prior to the last day of
the calendar year in which Executive's  Termination occurs,  Executive may waive
any or all rights and benefits  provided for herein which have been  received by
Executive; provided that prior to the end of such year Executive repays to Sonat
(or, if the benefit was received  from an employee  benefit plan trust,  to such
trust) the amount of the benefit received  together with interest thereon at the
minimum rate required to avoid imputed income.  Any waiver of benefits  pursuant
to this paragraph shall be irrevocable.  If Executive  waives a right or benefit
provided  for herein  and such  waiver is  determined  by the  Internal  Revenue
Service not to be  effective,  Sonat shall  indemnify  Executive for any federal
income and excise taxes Executive incurs as a result of that  determination,  so
as to put Executive in the position  Executive would have been in had the waiver
been given effect.

         (e)  Severability.  In the event that any  provision or portion of this
Agreement shall be determined to be invalid or unenforceable for any reason, the
remaining  provisions of this Agreement shall remain in full force and effect to
the fullest extent permitted by law.

         (f)  Successors.  This Agreement shall be binding upon and inure to the
benefit of Executive and  Executive's  personal  representative  and heirs,  and
Sonat and any successor  organization  or  organizations  which shall succeed to
substantially  all of the business  and  property of Sonat,  whether by means of
merger,  consolidation,  acquisition of substantially all of the assets of Sonat
or otherwise, including by operation of law.

         (g) Taxes. Any payment or delivery  required under this Agreement shall
be subject to all  requirements  of the law with regard to withholding of taxes,
filing,  making of reports and the like, and Sonat shall use its best efforts to
satisfy promptly all such requirements.

         (h) Governing  Law. This  Agreement  shall be governed and construed in
accordance with the laws of the State of Delaware.

         (i) Entire  Agreement.  This Agreement sets forth the entire  agreement
and  understanding  of the parties  hereto with  respect to the matters  covered
hereby,  and  incorporates  into one document any previous  severance  agreement
executed by the parties and all amendments thereto as of the date hereof.

         IN WITNESS  WHEREOF,  the parties have executed this  Agreement as July
23, 1998.

(a)  Amounts  include  the  Company's portion of the  captions as they relate to
     persons accounted for by the equity method.

(b)  These  amounts  represent  1/3 of rentals  which  approximate  the interest
     factor  applicable to such rentals of the Company and its  subsidiaries and
     continuing unconsolidated affiliates.

(c)  Earnings from continuing operations for the nine months ended September 30,
     1998 reflect ceiling test charges for the impairment of certain oil and gas
     properties and restructuring expenses primarily associated with a reduction
     in work force.  Earnings before income taxes were reduced  $1,050.2 million
     as a result of the ceiling test charges and restructuring  charge.  Because
     of these charges, earnings were inadequate to cover fixed charges of $143.8
     million  for the  nine  months  ended  September  30,  1998.  The  coverage
     deficiency was $862.4 million for the nine month period.

The Board of Directors and Stockholders
Sonat Inc.

Note 2 of Notes to Condensed  Consolidated  Financial  Statements  of Sonat Inc.
included in its Form 10-Q for the nine months ended September 30, 1998 describes
a  change  in the  method  of  accounting  for oil and gas  properties  from the
successful  efforts method to the full cost method. You have advised us that you
believe that the change is to a preferable method in your circumstances  because
of the following reasons:

 1.  The  Company  has  changed  its  oil  and gas  exploration  and  production
     strategic   direction  from  acquisitions  of  producing   properties  with
     significant   development  potential  to  an  exploratory  and  development
     drilling growth  strategy.  The Company believes that, due to its change in
     strategic direction, the full cost method provides for a better matching of
     revenues and expenses versus the successful  efforts  method,  and the full
     cost method more fairly  presents the cost of the reserves  acquired in the
     statement of financial position.

 2.  Reporting annual operating  results and financial  position on a successful
     efforts  basis  for  a  company  that  provides  for  its  growth   through
     exploration  drilling  provides a  different  reflection  of the  operating
     success of the  company  and the cost of  acquiring  reserves.  The Company
     believes that for a growing  exploratory  company a better  presentation of
     economic results is provided through the application of full cost method of
     accounting.  The full cost method  accurately  matches the cost of reserves
     obtained through an exploratory drilling program with the revenues produced
     through selling these reserves over a company's business cycle.

There are no  authoritative  criteria for  determining  a preferable  accounting
method  for  oil and  gas  properties  based  on the  particular  circumstances;
however, we conclude that the change in the method of accounting for oil and gas
properties is to an acceptable  alternative method which, based on your business
judgment to make this change for the reasons cited above,  is preferable in your
circumstances.  We have not  conducted  an audit in  accordance  with  generally
accepted auditing standards of any financial statements of the Company as of any
date or for any period subsequent to December 31, 1997; and therefore, we do not
express any opinion on any financial statements of Sonat Inc. subsequent to that
date.
