                       AGL RESOURCES INC. AND SUBSIDIARIES
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


1. General

AGL Resources Inc. is the holding company for Atlanta Gas Light Company ("AGLC")
and its wholly-owned subsidiary, Chattanooga Gas Company ("Chattanooga"),  which
are both natural gas local distribution utilities.  Additionally,  AGL Resources
Inc.  owns or has an  interest  in several  non-utility  subsidiaries  and joint
ventures.  AGL Resources Inc. and its subsidiaries are collectively  referred to
as "AGL Resources."

In the opinion of management,  the unaudited  condensed  consolidated  financial
statements  included herein reflect all normal recurring  adjustments  necessary
for a fair  statement  of the results of the interim  periods  reflected.  These
interim  financial  statements  and  notes are  condensed  as  permitted  by the
instructions to Form 10-Q, and should be read in conjunction  with the financial
statements  and the  notes  included  in the  annual  report on Form 10-K of AGL
Resources  for the fiscal year ended  September  30,  1999.  Due to the seasonal
nature of a portion of AGL Resources' businesses,  the results of operations for
the three-month  period are not necessarily  indicative of results of operations
for a twelve-month period.

Management makes estimates and assumptions when preparing  financial  statements
under generally accepted accounting principles.  Those estimates and assumptions
affect various matters, including:

- -    Reported  amounts of assets and  liabilities in our Condensed  Consolidated
     Balance Sheets as of the dates of the financial statements;

- -    Disclosure  of  contingent  assets and  liabilities  as of the dates of the
     financial statements;  and Reported amounts of revenues and expenses in our
     Condensed Statements of

- -    Consolidated Income during the reported periods.

Those estimates  involve  judgments with respect to, among other things,  future
economic  factors  that are  difficult  to predict  and are beyond  management's
control. Consequently, actual amounts could differ from our estimates.

Certain amounts in financial statements of prior years have been reclassified to
conform to the presentation of the current year.

2.  Overview  of the  Transition  from a  Regulated  to a  Competitive  Business
Environment

Pursuant  to  Georgia's  1997  Natural  Gas  Competition  and  Deregulation  Act
("Deregulation  Act"),  AGLC  unbundled  various  components  of its services to
end-use  customers.  Historically,  only  large,  interruptible  commercial  and
industrial  customers  had the option of purchasing  natural gas from  suppliers
other than AGLC and  transporting  such natural gas through AGLC's  distribution
system for delivery.  The Deregulation Act enabled AGLC to unbundle its delivery
service  and  other  related  services  from  the  sale of  natural  gas for all
customers,  thus allowing firm  residential  and small  commercial  customers to
purchase  natural  gas and  other  services  from  suppliers  other  than  AGLC.
Effective  October 1, 1999,  virtually  all of AGLC's 1.4 million  customers  in
Georgia  were  purchasing  natural  gas from  marketers  who were  approved  and
certificated ("certificated marketers") by the Georgia Public Service Commission
("GPSC").  As a result of the  Deregulation  Act,  AGLC has become  primarily  a
provider of delivery service and other related services.

                               Page 7 of 30 Pages

2.  Overview  of the  Transition  from a  Regulated  to a  Competitive  Business
Environment (Continued)

As a result of the  transition to  competition,  numerous  changes have occurred
with  respect to the  services  being  offered  by AGLC and with  respect to the
manner in which  AGLC  prices and  accounts  for those  services.  Consequently,
AGLC's future revenues and expenses will not follow  historical  patterns due to
the provision of delivery  services to end-use  customers which are priced based
upon straight fixed variable ("SFV") rates. The effect of SFV rates is to spread
evenly  throughout  the year AGLC's  recovery  of its  delivery  service  costs.
Although,  when compared to corresponding quarters of prior years, the effect of
SFV rates is to shift utility delivery  service revenues among quarters,  AGLC's
annual delivery service revenues should remain relatively  consistent on a going
forward basis.

AGLC  continues  to provide  intrastate  delivery  service  through its existing
pipeline system to end-use customers in Georgia,  but has exited the natural gas
sales  function.  AGLC's  delivery of natural gas remains  subject to the GPSC's
continued  regulation of delivery rates,  safety,  access to AGLC's system,  and
quality of service for all aspects of delivery service.

Certificated marketers,  including AGL Resources' marketing affiliate, SouthStar
Energy  Services  LLC  ("SouthStar"),  compete  to sell  natural  gas to end-use
customers  at  market-based   prices.   AGLC  allocates   delivery  capacity  to
certificated  marketers in proportion to the number and size of residential  and
small  commercial  customers  served  by each  certificated  marketer.  Delivery
capacity that is not used on any day to serve  residential and small  commercial
customers is made  available to large,  interruptible  commercial and industrial
customers.  Similarly, AGLC has allocated to certificated marketers the majority
of the  pipeline  storage  services  that it has under  contract,  along  with a
corresponding amount of inventory.

During the  transition  to  competition,  AGLC  continued  to provide  gas sales
service  to  customers  who had not yet  switched  to a  certificated  marketer.
Pursuant to a joint stipulation agreement with the GPSC, AGLC implemented a rate
structure for gas sales that ensured AGLC's  recovery of its purchased gas costs
incurred from October 6, 1998 through  September 30, 1999,  without creating any
significant  income or loss.  The joint  stipulation  agreement  provided  for a
true-up for any profit or loss outside of a specified  range during fiscal 1999.
During December 1999, as contemplated by the joint stipulation  agreement,  AGLC
paid $33 million in  over-collected  purchased gas costs to the GPSC. Since AGLC
paid the $33 million to the GPSC, the GPSC has  instituted a mechanism  pursuant
to which  certificated  marketers  will be required to provide  customers with a
credit on their  marketer's  bill.  To be eligible  for the refund  credit,  the
customer must have been on AGLC's system on May 25, 1999, and still connected as
of  April  3,  2000.   The  average  refund  per  customer  is  expected  to  be
approximately  $25.  (See Gas Cost Credits in the  Financial  Condition  section
contained  in Item 2 of Part I under the caption  "Management's  Discussion  and
Analysis of Results of Operations and Financial Condition.")

Also during the  transition  to  competition,  AGLC  continued  to bill  end-use
customers  who had not yet  switched  to  certificated  marketers  for gas sales
service and for certain ancillary  services.  These ancillary  services included
meter  reading,  billing,  bill  inquiry,  payment  processing,  and  collection
services.  Once an end-use customer switched to a certificated  marketer for gas
sales service, the Deregulation Act permitted AGLC to bill the marketer only for
the AGLC-provided  ancillary  services  actually used by the marketer.  AGLC was
unable,  however, to eliminate all of the costs associated with the provision of
ancillary  services as quickly as customers  switched to certificated  marketers
for natural  gas sales,  thereby  creating an  imbalance  between  revenues  and
expenses.

2.  Overview  of the  Transition  from a  Regulated  to a  Competitive  Business
Environment (Continued)

The Deregulation Act provides marketing standards and rules of business practice
to ensure that the benefits of a competitive natural gas market are available to
all  customers  on AGLC's  system.  It  imposes  on  certificated  marketers  an
obligation to serve end-use customers, and creates a universal service fund. The
universal  service fund  provides a method to fund the recovery of  certificated
marketers'  uncollectible  accounts and enables AGLC to expand its facilities to
serve the public interest.

3. Earnings Per Common Share; Common Stockholders'  Equity; and Share Repurchase
Program

Basic  earnings  per common  share is computed by dividing  income  available to
common  stockholders by the weighted average number of common shares outstanding
for the  period.  Diluted  earnings  per common  share  reflects  the  potential
dilution  that could occur when  common  share  equivalents  are added to common
shares  outstanding.  AGL  Resources'  only common share  equivalents  are stock
options  whose  exercise  prices were less than the average  market price of the
common  shares  for the  respective  periods.  As of March  31,  2000 and  1999,
respectively, options to purchase 3,400,466 and 2,199,643 shares of common stock
were  outstanding,  and were not included in the computation of diluted earnings
per common share because the exercise  prices of those options were greater than
the average market price of the common shares for the respective periods.

On October 5, 1999, the Board of Directors of AGL Resources authorized a plan to
repurchase up to 3.6 million  shares (6.3% of total  outstanding as of September
30,  1999) of AGL  Resources  common  stock  over a period  ending no later than
September 30, 2001. Open market purchases of the shares may be made from time to
time,  subject  to  availability,  and the  repurchased  shares  will be held in
treasury.  Under the share  repurchase  program,  during the three month  period
ended March 31, 2000, AGL Resources repurchased 2,813,600 shares of common stock
for a total of $48.2 million.  During the six month period ended March 31, 2000,
AGL Resources  repurchased 3,072,500 shares of common stock for a total of $52.7
million.

During the three month period and six month  period  ended March 31,  2000,  AGL
Resources   issued   149,449   shares  and  307,925   shares  of  common  stock,
respectively,  under  ResourcesDirect,  a direct  stock  purchase  and  dividend
reinvestment  plan;  the Retirement  Savings Plus Plan; the Long-Term  Incentive
Plan; and the Non-Employee Directors Equity Compensation Plan.

4. Accounting for Derivative Instruments and Hedging Activities

In June 1998,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial Accounting  Standards No. 133, "Accounting for Derivative  Instruments
and Hedging  Activities"  ("SFAS  133").  SFAS 133  establishes  accounting  and
reporting  standards for derivative  instruments,  including certain  derivative
instruments  embedded  in  other  contracts,  and for  hedging  activities.  AGL
Resources  will adopt SFAS 133 on October 1, 2000. The impact of SFAS 133 on AGL
Resources'  consolidated  financial  statements is under review and is currently
unknown.

5. Environmental Matters

Before natural gas was widely available in the Southeast,  AGLC manufactured gas
from  coal  and  other  fuels.  Those  manufacturing  operations  were  known as
"manufactured  gas plants," or "MGPs" which AGLC ceased  operating in the 1950s.
Because  of recent  environmental  concerns,  AGLC is  required  to  investigate
possible environmental contamination at those plants and, if necessary, clean up
any contamination.

                               Page 9 of 30 Pages


5. Environmental Matters (Continued)

AGLC has been  associated  with nine MGP sites in Georgia  and three in Florida.
Based on  investigations  to date,  AGLC believes that some cleanup is likely at
most of the sites.  In  Georgia,  the state  Environmental  Protection  Division
supervises  the  investigation  and cleanup of MGP sites.  In Florida,  the U.S.
Environmental Protection Agency has that responsibility.

For each of the MGP sites,  AGLC has  estimated its share of the likely costs of
investigation and cleanup.  AGLC currently  estimates that its total future cost
of  investigating  and cleaning up its MGP sites is between  $102.4  million and
$148.2 million.  That range does not include other potential  expenses,  such as
unasserted property damage or personal injury claims or legal expenses for which
AGLC may be held liable but for which  neither the  existence  nor the amount of
such  liabilities  can be reasonably  forecast.  Within that range,  AGLC cannot
identify  any single  number as a "better"  estimate of its likely  future costs
because its actual future  investigation and cleanup costs will be affected by a
number of contingencies that cannot be quantified at this time. Consequently, as
of March 31,  2000,  AGLC has  recorded  the lower end of the  range,  or $102.4
million,  as a liability,  which remains unchanged from December 31, 1999, and a
corresponding regulatory asset.

On April 24, 2000,  AGLC entered into an agreement with  ThermoRetec  Consulting
Corporation for the management of the environmental  investigations and cleanups
associated  with the MGP sites.  Management  does not believe the outsourcing of
the  management  will  have a  material  effect  on the  total  future  cost  of
investigating and cleaning up the MGP sites.

6. Segment Information

AGL Resources is organized into two operating segments: Utility and Non-utility.
Management evaluates segment performance based on net income, which includes the
effects of corporate expense allocations.  There were no material  inter-segment
sales during the three-month or six-month periods ended March 31, 2000 or 1999.

ITEM 2.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF RESULTS OF  OPERATIONS  AND
FINANCIAL CONDITION

Forward-Looking Statements

The Private Securities  Litigation Reform Act of 1995 allows public companies to
provide  cautionary remarks about  forward-looking  statements that they make in
documents  that  are  filed  with  the   Securities  and  Exchange   Commission.
Forward-looking  statements in our Management's  Discussion and Analysis include
statements about the following:

- -    Deregulation;
- -    Concentration of credit risk;
- -    Environmental investigations and cleanups; and
- -    Quantitative and qualitative disclosures about market risk.

Important  factors that could cause our actual  results to differ  substantially
from those in the forward-looking  statements  include,  but are not limited to,
the following:

- -    Changes in price and demand for natural gas and related products;
- -    Impact of changes in state and federal  legislation  and regulation on both
     the gas and electric industries;
- -    Effects and uncertainties of deregulation and competition,  particularly in
     markets  where  prices  and  providers  historically  have been  regulated,
     unknown risks related to nonregulated  businesses,  and unknown issues such
     as the stability of certificated marketers;
- -    Concentration of credit risk in certificated marketers;
- -    Industry consolidation;
- -    Changes in accounting policies and practices;
- -    Interest  rate  fluctuations,  financial  market  conditions,  and economic
     conditions, generally; and
- -    Uncertainties  about  environmental  issues and the related  impact of such
     issues.

Nature of Our Business

AGL Resources Inc. is the holding company for:

- -    Atlanta  Gas  Light  Company  ("AGLC")  and  its  wholly-owned  subsidiary,
     Chattanooga  Gas  Company  ("Chattanooga"),  which  are  natural  gas local
     distribution  utilities;
- -    AGL Energy Services, Inc. ("AGLE"), a gas supply services company; and
- -    Several non-utility subsidiaries.

AGL  Resources  and  its  subsidiaries  are  collectively  referred  to as  "AGL
Resources."

                              Page 12 of 30 Pages




AGLC conducts its primary business,  the distribution of natural gas, in Georgia
including  Atlanta,  Athens,  Augusta,  Brunswick,  Macon, Rome,  Savannah,  and
Valdosta.  Chattanooga  distributes natural gas in the Chattanooga and Cleveland
areas of Tennessee.  The Georgia Public Service  Commission  ("GPSC")  regulates
AGLC, and the Tennessee Regulatory Authority ("TRA") regulates Chattanooga. AGLE
is a nonregulated company that bought and sold the natural gas that was supplied
to  AGLC's  customers  during  the  deregulation   transition   period  to  full
competition  in  Georgia.  Currently,  AGLE  buys  and  sells  natural  gas  for
Chattanooga's customers.

AGLC  comprises  substantially  all  of AGL  Resources'  assets,  revenues,  and
earnings.  The  operations  and  activities  of  AGLC,  AGLE,  and  Chattanooga,
collectively,  are  referred  to as the  "utility."  The  utility's  total other
operating expenses include costs allocated from AGL Resources Inc.

UTILITY.  Utility operating  revenues decreased $218.9 million and cost of sales
decreased $203.5 million primarily due to the following factors:

- -    Pursuant to the Deregulation  Act,  Georgia  customers began to switch from
     AGLC to certificated marketers for natural gas purchases beginning November
     1, 1998. As of October 1, 1999, except for isolated  circumstances,  all of
     AGLC's  approximately  1.4 million Georgia customers had switched to or had
     been assigned to certificated  marketers.  As a result, AGLC sold less gas.
     The reduction in gas sold  resulted in a net decrease of $213.6  million in
     operating  revenues and a net decrease of $207.6 million in the cost of gas
     sold to end-use customers  resulting from the effect of customer  migration
     to  certificated  marketers.  Historically,  AGLC  recovered its actual gas
     costs, including carrying costs related to storage of gas inventories, from
     its customers;
- -    Chattanooga's  operating  revenues increased $4.1 million and cost of sales
     increased  $4.2  million  as a result of weather  that was colder  than the
     prior year; and
- -    A decrease of $9.4 million in delivery  service  revenue due to the loss of
     ancillary  service revenues and certain  transition  revenues of which $8.9
     million of the  decrease  was due to  customer  migration  to  certificated
     marketers.  Additionally,  AGLC's late  payment fee  revenue  from  end-use
     customers  decreased  $4.9 million.  This decrease was primarily due to the
     fact  that  AGLC no longer  billing  end-use  customers.  The  decrease  in
     delivery service revenue was partially offset by revenue  increases of $2.5
     million  related  to  customer  growth and $1.8  million  related to damage
     billing.

The  operating  margin  decreased  to $120.8  million for the three months ended
March 31, 2000 from $136.2  million for the same period last year.  The decrease
of $15.4 million was the result of the factors noted above. The operating margin
as a percentage  of operating  revenues  increased to 82.9% for the three months
ended March 31, 2000 from 37.3% for the same period last year. This increase was
primarily due to decreased revenues from gas sales and a corresponding  decrease
in cost of gas resulting from deregulation.

NON-UTILITY.  Non-utility  operating revenues increased to $14.3 million for the
three  months  ended March 31, 2000 from $10.4  million for the same period last
year.  The net  increase of $3.9  million  was  primarily  due to the  following
factors:

- -    An increase of $2.7  million in  Utilipro's  operating  revenues.  Utilipro
     engages  in the  sale of  integrated  customer  care  solutions  to  energy
     marketers.  Utilipro's  growth  in  revenue  over  the  previous  year  was
     primarily due to increased demand for its customer care services; and

- -    An increase of $1.9 million in Propane's operating  revenues.  The increase
     was due primarily to an increase in the selling  price per gallon  compared
     with the same period in fiscal 1999.

Non-utility  cost of sales  increased to $5.7 million for the three months ended
March 31, 2000 from $3.5 million for the same period last year.  The increase of
$2.2 million was primarily due to an increase in Propane's cost of gas resulting
from an  increase  in the cost per gallon as  compared  to the same  period last
year.

Non-utility  operating  margin  increased  to $8.6  million for the three months
ended  March 31,  2000 from $6.9  million  for the same  period  last year.  The
increase of $1.7 million was the result of the factors noted above.

Total Other Operating Expenses
Total other operating  expenses  increased to $91.9 million for the three months
ended  March 31,  2000 from $90.7  million  for the same  period  last year,  an
increase of 1.3%.

UTILITY.  Utility  total other  operating  expenses  decreased  $1.6  million as
compared  with the same period last year.  The decrease was  primarily  due to a
decrease in customer service expense related to billing,  bill inquiry,  payment
processing and collection  services resulting from the migration of customers to
certificated  marketers.  The  decrease was  partially  offset by an increase in
general and administrative  expense and an increase in depreciation  expense due
to increased depreciable property.

NON-UTILITY.  Non-utility total other operating  expenses increased $2.8 million
as  compared  with the same  period  last year  primarily  due to an increase in
Utilipro's operating expenses caused by increased demand for its services.  (see
Non-utility section under Operating Margin Analysis.)

Other Income/(Loss)
Other income  totaled  $12.4  million for the three months ended March 31, 2000,
compared  with other losses of $0.2  million for the same period last year.  The
increase in other income of $12.6 million is primarily due to an increase in AGL
Resources'  portion of  SouthStar's  income of $10.4 million from a loss of $1.9
million, an increase of $12.3 million.  The improved performance by SouthStar is
primarily due to an increase in customers  served and lower marketing  expenses,
compared to the same period last year.

Interest Expense
Interest expense decreased to $12.4 million for the three months ended March 31,
2000 from $13.6  million  for the same period  last year.  The  decrease of $1.2
million was primarily due to the following:
- -    A decrease of $0.9 million  resulting from  decreased  amounts of long-term
     debt outstanding during the period; and
- -    A decrease of  approximately  $0.5  million  resulting  from a reduction of
     interest  expense  related to  customer  deposits  as a result of  customer
     migration to certificated marketers.

Income Taxes
Income tax expense  increased to $13.2  million for the three months ended March
31,  2000 from $12.8  million for the same  period  last year.  The  increase in
income taxes of $0.4 million was due  primarily to an increase in the  effective
tax rate  partially  offset by a $1.1 million  decrease in income  before income
taxes  compared to the same period last year.  The increase in the effective tax
rate resulted from a reduction in certain tax reserves  related to the favorable
resolution of certain  outstanding  tax issues during the same period last year.
The effective  tax rate (income tax expense  expressed as a percentage of pretax
income) for the three months ended March 31, 2000 was 36.8% as compared to 34.6%
for the same period last year.

UTILITY.  Utility operating  revenues decreased $364.8 million and cost of sales
decreased $336.6 million primarily due to the following factors:

- -    Pursuant to the Deregulation  Act,  Georgia  customers began to switch from
     AGLC to certificated marketers for natural gas purchases beginning November
     1, 1998. As of October 1, 1999, except for isolated  circumstances,  all of
     AGLC's  approximately  1.4 million Georgia customers had switched to or had
     been assigned to certificated  marketers.  As a result, AGLC sold less gas.
     The reduction in gas sold  resulted in a net decrease of $350.9  million in
     operating  revenues and a net decrease of $345.0 million in the cost of gas
     sold to end-use customers  resulting from the effect of customer  migration
     to  certificated  marketers.  Historically,  AGLC  recovered its actual gas
     costs, including carrying costs related to storage of gas inventories, from
     its customers;
- -    Chattanooga's  operating  revenues increased $8.4 million and cost of sales
     increased  $8.5  million  as a result of weather  that was colder  than the
     prior year; and
- -    A decrease of $24.0 million in delivery  service revenue due to the loss of
     ancillary service revenues and certain  transition  revenues of which $20.0
     million of the  decrease  was due to  customer  migration  to  certificated
     marketers.  Additionally,  AGLC's late  payment fee  revenue  from  end-use
     customers  decreased  $9.9 million.  This decrease was primarily due to the
     fact  that  AGLC no longer  billing  end-use  customers.  The  decrease  in
     delivery service revenue was partially offset by revenue  increases of $4.7
     million  related  to  customer  growth and $2.0  million  related to damage
     billing.

The operating  margin decreased to $240.3 million for the six months ended March
31, 2000 from $268.5  million  for the same  period last year.  The  decrease of
$28.2 million was the result of the factors noted above. The operating margin as
a percentage of operating  revenues  increased to 75.8% for the six months ended
March 31,  2000 from 39.4% for the same  period  last year.  This  increase  was
primarily due to decreased revenues from gas sales and a corresponding  decrease
in cost of gas resulting from deregulation.

NON-UTILITY.  Non-utility  operating revenues increased to $25.3 million for the
six months  ended  March 31,  2000 from $17.1  million  for the same period last
year.  The net  increase of $8.2  million  was  primarily  due to the  following
factors:
- -    An increase of $6.0 million in Utilipro's  operating  revenues.  Utilipro's
     growth in revenue was  primarily  due to increased  demand for its customer
     care services; and
- -    An increase of $3.2 million in Propane's operating  revenues.  The increase
     was due to an increase in the selling  price per gallon  compared  with the
     same period in fiscal 1999.

Non-utility  cost of sales  increased  to $8.5  million for the six months ended
March 31, 2000 from $5.6 million for the same period last year.  The increase of
$2.9 million was primarily due to an increase in Propane's cost of gas resulting
from an  increase  in the cost per gallon as  compared  to the same  period last
year.

Non-utility operating margin increased to $16.8 million for the six months ended
March 31, 2000 from $11.5 million for the same period last year. The increase of
$5.3 million was the result of the factors noted above.

Total other  operating  expenses  increased to $186.1 million for the six months
ended  March 31, 2000 from  $179.9  million  for the same  period last year,  an
increase of 3.4%.

UTILITY.  Utility  total other  operating  expenses  decreased  $4.4  million as
compared  with the same period last year.  The decrease was  primarily  due to a
decrease in customer service expense related to billing,  bill inquiry,  payment
processing and collection  services and a decrease in bad debt expense resulting
from the migration of customers to  certificated  marketers.  The decreases were
partially  offset  by  increases  in  general  and  administrative  expense  and
depreciation expense.

NON-UTILITY.  Non-utility total other operating expenses increased $10.6 million
as  compared  with the same  period  last year  primarily  due to an increase in
Utilipro's operating expenses caused by increased demand for its services.  (See
Non-utility section under Operating Margin Analysis.).

Other Income/(Loss)
Other  income  totaled  $19.3  million for the six months  ended March 31, 2000,
compared  with other losses of $8.1  million for the same period last year.  The
increase in other income of $27.4  million was  primarily  due to the  following
factors:
- -    AGL  Resources'  portion of SouthStar's  income  increased to $15.2 million
     from a loss of $3.3  million,  an increase of $18.5  million.  The improved
     performance  by  SouthStar  was  primarily  due to an increase in customers
     served and lower marketing expenses, compared to the same period last year;
     and
- -    During the first six months of fiscal 1999, AGL Resources  recorded pre-tax
     losses  related to its interests in Sonat  Marketing  Company L.P.  ("Sonat
     Marketing")  and Sonat  Power  Marketing  L.P.  ("Sonat  Power  Marketing")
     totaling  approximately  $5.3 million.  AGL Resources sold its interests in
     Sonat  Marketing  and Sonat Power  Marketing  during the fourth  quarter of
     fiscal 1999.

Interest Expense
Interest  expense  decreased to $24.6 million for the six months ended March 31,
2000 from $27.8  million  for the same period  last year.  The  decrease of $3.2
million was primarily due to the following:
- -    A decrease of $1.1 million  resulting from  decreased  amounts of long-term
     debt outstanding during the period; and
- -    A decrease of  approximately  $1.0  million  resulting  from a reduction of
     interest  expense  related to  customer  deposits  as a result of  customer
     migration to certificated marketers.

Income Taxes
Income tax expense increased to $22.8 million for the six months ended March 31,
2000 from $21.0  million for the same period last year.  The  increase in income
taxes of $1.8  million was due to an increase  in the  effective  tax rate and a
$1.5 million  increase in income before income taxes compared to the same period
last year.  The increase in the  effective tax rate resulted from a reduction in
certain tax reserves related to the favorable  resolution of certain outstanding
tax issues during the same period last year.  The effective tax rate (income tax
expense  expressed  as a percentage  of pretax  income) for the six months ended
March 31, 2000 was 36.4% as compared to 34.4% for the same period last year.

Financial Condition

Seasonality of Business
Historically,  the utility business has been seasonal in nature,  resulting in a
substantial  increase in accounts receivable from customers from September 30 to
March  31  due  to  higher  billings  during  colder  weather.  As a  result  of
deregulation  and the  implementation  of SFV  rates,  the  seasonality  of both
expenses and revenues related to AGLC's Georgia  operations has been eliminated.
However, the operations of SouthStar, Chattanooga, and Propane are seasonal, and
those entities will likely experience greater profitability in the winter months
than in the  summer  months.  (See Note 2.  Overview  of the  Transition  from a
Regulated to a Competitive Business Environment.)

Inventory of natural gas stored  underground  decreased $30.1 million during the
six months  ended  March 31, 2000  primarily  due to the  assignment  of most of
AGLC's  inventories to  certificated  marketers as a result of the  Deregulation
Act.  AGLC will  continue to maintain  small amounts of inventory of natural gas
stored  underground  in order to optimize the operation of its gas  distribution
system.

AGL Resources  historically meets its liquidity  requirements  through operating
cash flow and the issuance of short-term  debt.  Short-term lines of credit with
various banks provide for direct  borrowings and are subject to annual  renewal.
Availability under the current lines of credit ranges up to $180 million.

Short-term debt increased  $109.5 million to $111.0 million as of March 31, 2000
from $1.5 million as of September 30, 1999. The increase in short-term  debt was
primarily due to the repayment of $50 million of AGLC's  long-term  debt,  which
matured  during the six months ended March 31, 2000,  and the  repurchase of 3.1
million shares of common stock for a total of $52.7 million.  Management expects
to obtain other  long-term  financing  in fiscal 2001 to replace the  short-term
debt that was used for these purposes.

Operating  cash flow  decreased to $72.5  million for the six months ended March
31, 2000 as compared to $165.8  million for the same period last year  primarily
due to a decrease in gas cost credits. (See Gas Cost Credits section below.)

Management  believes available credit will be sufficient to meet working capital
needs both on a short and long-term basis. However, capital needs depend on many
factors and AGL Resources may seek additional  financing  through debt or equity
offerings in the private or public markets at any time.

Transition to Competition

UTILITY.  The regulated rate structure  under which AGLC unbundled its gas sales
and  delivery  service  assumed  that AGLC's  costs  associated  with  providing
customer  service  decreased  each time a customer  switched  to a  certificated
marketer for gas sales  service,  and such costs would be eliminated at the time
the switch was made. In fact, a significant portion of the costs associated with
customer service activities  ("ancillary  services"),  including  billing,  bill
inquiry, payment processing and collection services, could not be eliminated for
a period of up to several  months,  during  which AGLC  continued to incur these
expenses.  The accelerated pace of customer migration to certificated  marketers
also required AGLC to incur additional customer service expenses, not originally
provided for in regulated  rates,  in order to maintain a high level of customer
service during the transition to competition.  During the six months ended March
31,  2000,  AGLC  aggressively  pursued  the  elimination  of these  expenses by
implementing  various cost  reduction  and  operational  excellence  strategies.
Management  believes that those  strategies  have been effective and that AGLC's
operating expenses are approaching an appropriate level.

The Deregulation Act authorizes an electing  distribution company, like AGLC, to
recover prudently  incurred costs that are found by the GPSC to be "stranded" as
a result of the transition to competition, and necessary to provide a reasonable
rate of return.  On June 25,  1999,  AGLC  filed a request  with the GPSC for an
accounting order (the "Order"), which would allow AGLC to defer transition costs
which are considered by AGLC to be "stranded." The Order,  which was approved on
October 19,  1999,  allows AGLC to defer these costs if such costs are  incurred
from October 1, 1999 to September  30, 2000,  and recovery is necessary in order
for AGLC to earn the 11% return on common  stockholders'  equity approved by the
GPSC in AGLC's last rate case.  In order to be  deferred,  the cost must also be
one that:
- -    AGLC is still  incurring  but,  as a result of  deregulation,  is no longer
     receiving revenue from the rate or rates which were set based on that cost;
- -    Is prudently incurred; and
- -    Cannot be mitigated.

As of March 31, 2000, AGLC has deferred a net amount of $2.9 million in expenses
related to deregulation and recorded a regulatory asset in that amount.

NON-UTILITY.  AGL Resources  Inc. has entered into a definitive  agreement  that
will combine its propane  operations,  presently operated through Propane,  with
the propane operations of Atmos Energy Corporation,  Dallas TX; Piedmont Natural
Gas Company,  Inc.,  Charlotte,  NC; and TECO Energy,  Inc., Tampa FL. The joint
venture, which will be called U.S. Propane, will be among the 10 largest propane
retailers in the nation with  approximately  200,000 customers and operations in
Alabama,  Georgia,  South  Carolina,   Florida,  Kentucky,  North  Carolina  and
Tennessee. The transaction is expected to be completed by June 30, 2000.

Concentration of Credit Risk
AGLC has  concentration  of credit risk related to the  provision of services to
certificated  marketers.  At September 30, 1998, AGLC billed  approximately  1.4
million end-use customers in Georgia for its services. In contrast, at March 31,
2000, AGLC billed 14 certificated  and active marketers in Georgia for services,
who, in turn, billed end-use customers.

As of March 31, 2000,  54.6% of AGL Resources'  total gas  receivables  were due
from four of the 14 certificated and active marketers plus one inactive marketer
and 8.2% were due from end-use customers in Georgia who migrated to certificated
marketers late in fiscal 1999 or who were randomly  assigned.  Beginning October
1, 1999, only gas receivables primarily  attributable to Chattanooga will be due
from end-use  customers.  As a result,  in fiscal 2000, a  significantly  higher
percentage  of AGL  Resources'  total gas  receivables  will be due from Georgia
certificated marketers than was the case in prior years.

Several   factors   mitigate  the  risks  to  AGL  Resources  of  the  increased
concentration of credit that has resulted from deregulation.  First, in order to
obtain a certificate from the GPSC, a certificated  marketer must demonstrate to
the GPSC,  among other  things,  that it possesses  satisfactory  financial  and
technical  capability  to render  the  certificated  service.  Second,  AGLC has
instituted certain practices and imposed certain requirements designed to reduce
credit risk. These include:
- -    Pursuant  to AGLC's  tariff,  each  certificated  marketer  is  required to
     maintain  security  for its  obligations  to AGLC in an amount  equal to at
     least two times the marketer's  estimated  maximum  monthly bill and in the
     form of a cash  deposit,  letter of credit,  surety bond or guaranty from a
     creditworthy guarantor; and
- -    Intrastate delivery service is billed in advance rather than in arrears.

                              Page 21 of 30 Pages



AGLC  also  faces  potential  credit  risk in  connection  with  assignments  to
certificated  marketers  of  interstate  pipeline   transportation  and  storage
capacity.   Although  AGLC  has  assigned  this  capacity  to  the  certificated
marketers,  in the  event  that  the  certificated  marketers  fail  to pay  the
interstate  pipelines for the capacity,  the interstate  pipelines  would in all
likelihood seek repayment from AGLC. This risk is mitigated somewhat by the fact
that the interstate  pipelines  require the  certificated  marketers to maintain
security for their  obligations to the  interstates  arising out of the assigned
capacity.

On October 26, 1999,  Peachtree Natural Gas, LLC ("Peachtree"),  one of the five
largest  certificated  marketers in Georgia based on customer  count,  filed for
protection under Chapter 11 of the United States Bankruptcy Code. As of the date
of  Peachtree's  bankruptcy  filing,  Peachtree  owed AGLC  approximately  $14.3
million for pre-petition  delivery  service and other services and charges,  and
AGLC held $11 million of surety bonds as security for  Peachtree's  obligations.
The amount owed to AGLC does not include amounts owed by Peachtree to interstate
pipelines for assigned capacity.  Based upon proofs of claim filed by interstate
pipelines in Peachtree's  bankruptcy  proceeding,  as of the date of Peachtree's
filing,  Peachtree  owed  interstate  pipelines  approximately  $3.4 million for
assigned capacity. In December 1999, Shell Energy Services Company, L.L.C. began
serving the firm customers  formerly served by Peachtree.  AGLC has been paid in
full for all  post-petition  delivery  and other  services  provided  by AGLC to
Peachtree.

Capital Expenditures
Capital  expenditures for construction of distribution  facilities,  purchase of
equipment,  and other general  improvements were $79.5 million for the six-month
period  ended  March 31, 2000 as  compared  to $61.8  million for the  six-month
period  ended  March  31,  1999.  The  increase  of $17.7 million  is  primarily
attributable to the capital  expenditures  incurred for the accelerated pipeline
replacement  plan.  (See AGLC Pipeline  Safety  section  under State  Regulatory
Activity.)  Typically,  funding for capital  expenditures is provided  through a
combination of internal and external sources.

Common Stock
During the six months ended March 31, 2000, AGL Resources  repurchased 3,072,500
shares of common  stock for a total of $52.7  million  pursuant to a  previously
announced stock repurchase plan.  During that same period,  AGL Resources issued
307,925  shares of common stock under  ResourcesDirect,  a direct stock purchase
and dividend  reinvestment plan; the Retirement Savings Plus Plan; the Long-Term
Incentive Plan; and the Non-Employee Directors Equity Compensation Plan.

Ratios
As of March 31, 2000, AGL Resources' capitalization ratios consisted of:

      46.6% long-term debt;
       5.7% preferred securities; and
      47.7% common equity.

Gas Cost Credits
Gas cost  credits  decreased  to $2.0  million  as of March 31,  2000 from $37.9
million as of September 30, 1999. The decrease is primarily due to a $33 million
payment to the GPSC during  December 1999, and payments  totaling  approximately
$2.5 million to buyout and terminate  remaining  long-term gas supply contracts.
In accordance with the January 26, 1999 joint stipulation agreement entered into
with the GPSC,  AGLC  recognized  profits  of $1.0  million  in fiscal  1999 and
recorded  a  liability  for  the  remaining  over-collection  of  gas  costs  in
accordance  with SFV  rates.  (See Note 2.  Overview  of the  Transition  from a
Regulated to a Competitive Business Environment.)

                              Page 22 of 30 Pages



Since AGLC paid the $33 million to the GPSC, the GPSC has instituted a mechanism
pursuant to which  certificated  marketers will be required to provide customers
with a credit on their  marketer's  bill. To be eligible for the refund  credit,
the  customer  must  have  been on  AGLC's  system  on May 25,  1999,  and still
connected as of April 3, 2000. The average refund per customer is expected to be
approximately $25.


State Regulatory Activity

In January 2000,  the GPSC approved a new tariff to be made available to certain
agricultural processing customers.  Approximately 350 commercial poultry growers
and other  similarly  situated  customers  switched to other fuels following the
introduction  of new rates in 1998.  The new tariff is expected to allow many of
these customers to return to natural gas to fuel their operations.

In March 2000, the GPSC approved a plan to refund  approximately  $34 million to
retail end-use customers of certificated marketers.  The refund is a result of a
positive balance in AGLC's purchased gas adjustment  ("PGA") which accrued while
AGLC was still a retail  provider  of natural  gas.  The refund has no effect on
AGLC's earnings. However, AGLC was allowed to recover approximately $0.8 million
from the PGA balance prior to disbursement of refunds in order to cover bad debt
balances of certain customers who were eligible for refunds.

The GPSC also  approved  the release of $0.2  million  during the quarter  ended
March 31, 2000 from the  Universal  Service  Fund  ("USF") for system  expansion
projects in AGLC's  distribution  system. The USF was established as a component
of gas  deregulation in Georgia in order to, among other things,  fund expansion
of  AGLC's  distribution  system  in  areas  where  it  would  otherwise  not be
economically  feasible to do so. For the six months  ended March 31,  2000,  USF
contributions totaled $0.3 million for expansion projects.

On February 1, 2000, the TRA approved a special contract for the Company with an
industrial  customer  in order to avoid  bypass  of the  distribution  system in
Tennessee.  The special contract allows the Company to recover 90 percent of the
margin  lost from this  industrial  customer  through a  surcharge  to all other
customers.

Regulatory Accounting
AGL Resources has recorded  regulatory  assets and  liabilities in its Condensed
Consolidated Balance Sheets in accordance with Statement of Financial Accounting
Standards No. 71,  "Accounting  for the Effects of Certain Types of  Regulation"
("SFAS 71").

In July 1997,  the  Emerging  Issues  Task Force  ("EITF")  concluded  that once
legislation is passed to deregulate a segment of a utility and that  legislation
includes  sufficient  detail for the  enterprise to determine how the transition
plan will affect that segment,  SFAS 71 should be discontinued  for that segment
of  the  utility.  The  EITF  consensus  permits  assets  and  liabilities  of a
deregulated  segment to be  retained if they are  recoverable  through a segment
that remains regulated.

AGLC Pipeline Safety
On January 8, 1998,  the GPSC issued  procedures and set a schedule for hearings
about alleged pipeline safety violations.  On July 21, 1998, the GPSC approved a
settlement  between  AGLC and the  Adversary  Staff of the GPSC  that  details a
10-year  replacement program for approximately 2,300 miles of cast iron and bare
steel pipe. Over that 10-year period, AGLC will recover from customers,  through
billings to certificated marketers,  the costs related to the program net of any
cost savings from the replacement program.

                              Page 23 of 30 Pages



During the six months ended March 31, 2000,  approximately 111 miles of pipe was
replaced   pursuant  to  the  program.   During  that  period,   AGLC's  capital
expenditures  and operation  and  maintenance  expenses  related to the pipeline
replacement   program  were  approximately   $23.3  million  and  $4.3  million,
respectively.  All such amounts will be recovered  through a combination  of SFV
rates and a  regulatory  mechanism.  On October 1, 1999,  AGLC began  recovering
costs of the program  through the  regulatory  mechanism.  The amount  recovered
through March 31, 2000 was approximately $1.0 million.

Environmental

AGLC has been  associated  with nine MGP sites in Georgia  and three in Florida.
Based on  investigations  to date,  AGLC believes that some cleanup is likely at
most of the  sites.  AGLC  currently  estimates  that its total  future  cost of
investigating and cleaning up its MGP sites is between $102.4 million and $148.2
million. AGLC has two ways of recovering investigation and cleanup costs. First,
the GPSC has approved an "Environmental Response Cost Recovery Rider." It allows
the  recovery  of costs of  investigation,  testing,  cleanup,  and  litigation.
Because of that rider,  AGLC has recorded a regulatory  asset in the same amount
as the recorded liability for investigation and cleanup. The second way AGLC can
recover costs is by exercising  the legal rights AGLC believes it has to recover
a share of its costs  from  other  potentially  responsible  parties,  typically
former  owners or operators of the MGP sites.  AGLC has been  actively  pursuing
those  recoveries.  There were no material  recoveries  during the quarter ended
March 31, 2000.


Federal Regulatory Activity

FERC Order 636:  Transition  Costs  Settlement  Agreements
The  Federal  Energy  Regulatory  Commission  ("FERC")  issued  Order No. 637 on
February 9, 2000. The order revises the FERC's rules governing the operations of
the utility's interstate pipeline suppliers. Among other things, the FERC:
- -    Permitted  holders of firm  pipeline  capacity to release  the  capacity to
     other shippers at a price greater than the pipeline's  maximum rate for the
     same capacity on an experimental basis through September 30, 2002;
- -    Authorized  pipelines  to propose  different  rates for  services  rendered
     during  periods of peak usage and to propose  rates that would differ based
     on the length of the customer's contract; and
- -    Declined,  for the present time, to permit pipelines and their customers to
     establish  individually  negotiated  terms and  conditions  of service that
     depart from generally applicable pipeline tariff rules.

The  utility  cannot  predict  how  these  revisions  may   potentially   affect
operations.

The  FERC  has  required  the  utility,  as well as  other  interstate  pipeline
customers,  to pay  transition  costs  associated  with  the  separation  of the
suppliers'  transportation  and  gas  supply  services.  Based  on its  pipeline
suppliers' filings with the FERC, the utility estimates the total portion of its
transition costs from all its pipeline  suppliers will be  approximately  $107.9
million. As of March 31, 2000,  approximately  $107.4 million of those costs had
been incurred and were being  recovered  primarily from the utility's  customers
under rates charged for the  distribution of gas. AGLC's remaining costs will be
recovered from certificated marketers.

                              Page 24 of 30 Pages



The utility  continues to pay transition  costs to Southern  Natural Gas Company
("Southern") pursuant to a restructuring settlement that resolves all transition
cost issues for Southern. Under the Southern settlement,  the utility's share of
Southern's transition costs is approximately $89.7 million, of which the utility
incurred $89.2 million as of March 31, 2000.

On March 10, 2000, Southern filed a settlement to resolve all issues arising out
of its  September 1, 1999 general rate case  filing.  Among other  matters,  the
settlement  provides  for the  termination  of  Southern's  interstate  pipeline
affiliate,  South Georgia Natural Gas Company ("South  Georgia"),  as a separate
entity, with Southern absorbing South Georgia's  facilities and operations.  The
settlement rates would represent a decrease of approximately $6 million per year
under AGLC's existing contracts for firm interstate pipeline capacity.  The FERC
has authorized  Southern to implement the  settlement  rates on an interim basis
effective March 1, 2000, pending action by the FERC on the settlement. In return
for the rate  reduction  firm  contract  holders  were  required to extend their
existing  contracts by three years.  The utility has filed  comments  requesting
that the FERC approve the settlement.

AGLC is involved in three Transcontinental Gas Pipe Line Corporation ("Transco")
rate cases,  which concern  rates in effect since  September 1, 1995, as well as
proposed  changes to take effect  prospectively.  These rate  proceedings are at
various stages of litigation  before the FERC, and none of these proceedings are
final. At the present time, AGLC cannot predict the effect of these  proceedings
on its rates or operations.


Environmental Matters

Before natural gas was widely available in the Southeast,  AGLC manufactured gas
from  coal  and  other  fuels.  Those  manufacturing  operations  were  known as
"manufactured  gas plants",  or "MGPs" which AGLC ceased operating in the 1950s.
Because  of recent  environmental  concerns,  AGLC is  required  to  investigate
possible environmental contamination at those plants and, if necessary, clean up
any contamination.

AGLC has been  associated  with nine MGP sites in Georgia  and three in Florida.
Based on  investigations  to date,  AGLC believes that some cleanup is likely at
most of the sites.  In  Georgia,  the state  Environmental  Protection  Division
supervises  the  investigation  and cleanup of MGP sites.  In Florida,  the U.S.
Environmental Protection Agency has that responsibility.

For each of the MGP sites,  AGLC has  estimated its share of the likely costs of
investigation and cleanup.  AGLC currently  estimates that its total future cost
of  investigating  and cleaning up its MGP sites is between  $102.4  million and
$148.2 million.  That range does not include other potential  expenses,  such as
unasserted property damage or personal injury claims or legal expenses for which
AGLC may be held liable but for which  neither the  existence  nor the amount of
such  liabilities  can be reasonably  forecast.  Within that range,  AGLC cannot
identify  any single  number as a "better"  estimate of its likely  future costs
because its actual future  investigation and cleanup costs will be affected by a
number of contingencies that cannot be quantified at this time. Consequently, as
of March 31,  2000,  AGLC has  recorded  the lower end of the  range,  or $102.4
million, as a liability,  which remains unchanged from September 30, 1999, and a
corresponding   regulatory  asset.  (See   Environmental   section  under  State
Regulatory Activity.)

On April 24, 2000,  AGLC entered into an agreement with  ThermoRetec  Consulting
Corporation for the management of the environmental  investigations and cleanups
associated  with the MGP sites.  Management  does not believe the outsourcing of
the  management  will  have a  material  effect  on the  total  future  cost  of
investigating and cleaning up the MGP sites.

ITEM 3. QUANTITATIVE AND QUALITATIVE  DISCLOSURE ABOUT MARKET RISK

All financial  instruments  and positions held by AGL Resources  described below
are held for purposes other than trading.

Interest Rate Risk
AGL  Resources'  exposure  to market risk  related to changes in interest  rates
relates  primarily to its borrowing  activities.  A hypothetical 10% increase or
decrease in interest rates related to AGL Resources'  variable rate debt ($111.0
million  outstanding  as of March 31, 2000) would not have a material  effect on
results of operations or financial  condition over the next 12 months.  The fair
value of AGL Resources'  long-term debt and capital securities also are affected
by changes in  interest  rates.  A  hypothetical  10%  increase  or  decrease in
interest  rates would not have a material  effect on the estimated fair value of
AGL Resources'  long-term  debt or capital  securities.  Additionally,  the fair
value of outstanding  long-term  debt and capital  securities has not materially
changed since  September  30, 1999.  During the six months ended March 31, 2000,
AGL Resources repaid $50.0 million of long-term debt.

                                  RECENT EVENTS


On May 8, 2000,  AGL Resources  entered into a definitive  agreement to purchase
Virginia Natural Gas ("VNG"),  a wholly owned subsidiary of Dominion  Resources,
for $500  million in cash.  The purchase  price  includes $22 million in working
capital. Under the agreement, AGL Resources would acquire all of the outstanding
stock of VNG.  At the option of the  seller,  the parties may elect to treat the
transaction  as a sale of assets for tax  purposes,  commonly  referred  to as a
Section 338(h)(10) election, in which case the purchase price shall be increased
to $550  million  to  reflect  the  increased  value of the  transaction  to AGL
Resources. The transaction is conditioned, among other things, upon approvals of
various   regulatory   agencies,   including  the  Virginia  State   Corporation
Commission, and is expected to close by December 31, 2000.

In connection  with the  acquisition  of VNG, AGL Resources  intends to register
with the  Securities  and Exchange  Commission  as a holding  company  under the
Public Utility Holding Company Act of 1935.
