Business Overview

Organizational Structure

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.

                                       1
<PAGE>

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

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 which 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 operations
expenses include costs allocated from AGL Resources Inc.

AGL Resources currently owns or has an interest in the following non-utility
businesses:

 .  SouthStar Energy Services LLC ("SouthStar"), a joint venture among a
   subsidiary of AGL Resources Inc. and subsidiaries of Dynegy, Inc. and
   Piedmont Natural Gas Company. SouthStar markets natural gas and related
   services to residential and small commercial customers in Georgia and to
   industrial customers in the Southeast. SouthStar began marketing natural gas
   to customers in Georgia during the first quarter of fiscal 1999 under the
   trade name "Georgia Natural Gas Services;"

 .  AGL Investments, Inc., which currently manages certain non-utility businesses
   including:

   .  AGL Propane, Inc. ("Propane"), which engages in the sale of propane and
      related products and services in Georgia, Alabama, Tennessee and North
      Carolina;

   .  Trustees Investments, Inc., which owns Trustees Gardens, a residential
      and retail development located in Savannah, Georgia; and

   .  Utilipro, Inc. ("Utilipro"), in which AGL Resources has an 85% ownership
      interest and which engages in the sale of integrated customer care
      solutions and billing services to energy marketers in the United States
      and Canada;

 .  AGL Peaking Services, Inc., which owns a 50% interest in Etowah LNG Company
   LLC ("Etowah"), a joint venture with Southern Natural Gas Company. Etowah was
   formed for the purpose of constructing, owning, and operating a liquefied
   natural gas peaking facility.


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 were
purchasing natural gas from marketers who were approved and certificated by the
GPSC ("certificated marketers").

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 the same pattern as they
have historically.

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.

                                       2
<PAGE>

Since July 1, 1998, AGLC's charges for delivery service to end-use customers
have been based on a straight fixed variable ("SFV") rate design. Under SFV
rates, delivery service costs are recovered throughout the year consistent with
the way those costs are incurred. Prior to the implementation of SFV rates, AGLC
recovered the majority of its delivery service costs volumetrically based on the
amount of natural gas consumed by end-use customers. As a result, AGLC
historically recovered a disproportionately large share of its delivery costs in
the winter months and a disproportionately small share of its delivery costs in
the summer months. 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 with annual delivery service
revenues of prior years.

Certificated marketers, including AGL Resources' marketing affiliate, 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.

On May 3, 1999, pursuant to the Deregulation Act, the GPSC issued an order
establishing a final 100 day period for customers who had not yet chosen a
certificated marketer to make a choice. Customers who did not choose a
certificated marketer were randomly assigned to a certificated marketer under
the rules issued by the GPSC.

Certificated marketers were randomly assigned customers in proportion to their
respective market share as of August 11, 1999, and began serving those customers
on October 1, 1999. As a result, AGLC has exited the natural gas sales business
and, except for isolated circumstances, is responsible only for delivery service
for residential and small commercial customers.

During the transition to competition, AGLC continued to provide gas sales
service to customers who had not yet switched to a certificated marketer.  On
January 26, 1999, AGLC entered into a joint stipulation agreement with the GPSC
to resolve certain gas sales service issues. Among other requirements in the
joint stipulation agreement, AGLC implemented a rate structure for gas sales,
beginning with February 1999 bills, that more closely reflected customers'
actual gas usage and included a demand charge for fixed costs associated with
gas sales. This rate structure for gas sales service 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.

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 include
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.

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

State Regulatory Matters

During fiscal 1999, AGLC unbundled, or separated, all services to its natural
gas customers in Georgia; allocated delivery capacity to certificated marketers
who sell the gas commodity to residential and small commercial customers; and
created a secondary market for large commercial and industrial transportation
capacity. (See Overview of the Transition from a Regulated to a Competitive
Business Environment section under Business Overview.)

Daily Balancing Services; EBB.  In September 1999, the GPSC approved the
application of daily balancing services and related charges to certificated
marketers serving retail customers on AGLC's system. This decision allows AGLC
to operate its delivery system in a reliable manner and provides for full
recovery of costs incurred for system imbalances. Along with the GPSC's order on
daily balancing, AGLC's Electronic Bulletin Board ("EBB") was declared fully
operational. This declaration was a requirement in order for daily balancing to
become effective.

Regulatory Accounting. AGL Resources has recorded regulatory assets and
liabilities in its 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.

The Deregulation Act allows deregulation of natural gas sales and the separation
of some ancillary services of local natural gas distribution companies. However,
the rates that AGLC, as the local gas distribution company, charges to transport
natural gas through its intrastate pipeline system will continue to be regulated
by the GPSC. Therefore, the continued application of SFAS 71 is appropriate for
regulatory assets and liabilities related to AGLC's delivery services.

AGLC Pipeline Safety Program. 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.

During fiscal 1999, approximately 247 miles of pipe was replaced pursuant to the
program. Also during fiscal 1999, AGLC's capital expenditures and operation and
maintenance expenses related to the pipeline replacement program were
approximately $43.2 million and $11.5 million, respectively. All such amounts
will be recovered through a combination of SFV rates and a regulatory mechanism.

Weather Normalization. The weather normalization adjustment rider ("WNAR")
authorized by the TRA to offset the impact of unusually cold or warm weather on
customer billings and operating margin remains in effect for Chattanooga. The
WNAR in  effect for AGLC was discontinued for fiscal 1999 by the GPSC when the
SFV rate structure became effective.

Inventory Assignment. Pursuant to the Deregulation Act, certificated marketers,
including AGLC's marketing affiliate, began selling natural gas to firm end-use
customers at market-based prices in November 1998. Part of the unbundling
process is the allocation of certain pipeline services that AGLC has under
contract, including interstate pipeline transportation and gas storage. In
particular, AGLC has allocated the majority of its pipeline storage services
that it has under contract to the certificated marketers along with a
corresponding amount of inventory based on the respective market share of the
certificated marketers. Following the rules of AGLC's tariff, the sale price was
the weighted-average cost of the storage inventory at the time of sale. AGLC
changed its inventory costing method for its gas inventories from first-in,
first-out to weighted average effective October 1, 1998. The weighted-average
cost-flow assumption provides for a more equitable pricing method for the sale
of gas inventories to certificated marketers.

                                       4
<PAGE>

As of September 30, 1999, AGLC had $43.0 million in gas storage. This amount
represents:

 .  Unassigned gas storage as of September 30, 1999, to serve unassigned
   customers; and

 .  AGLC's  retained storage,  that represents the under ground storage capacity
   retained by AGLC to balance temporary differences between marketer's expected
   demand and actual demand.

Certain gas storage inventory was unassigned at September 30, 1999 because all
customers had not been assigned.  Customers are switched to certificated
marketers on the first day of the month following the receipt of a switch
request. At September 30, 1999, approximately 18% of the customers had not been
switched to certificated marketers.  Such customers were switched on October 1,
1999, with the exception of approximately 15,000 customers. The remaining
customers are expected to switch during the first quarter of fiscal 2000. The
resulting decrease in gas inventory on October 1, 1999 was approximately $19.0
million.

Federal Regulatory Matters

FERC Order 636: Transition Costs Settlement Agreements. The utility purchases
natural gas transportation and storage services from interstate pipeline
companies, and the Federal Energy Regulatory Commission ("FERC") regulates those
services and the rates the interstate pipeline companies charge the utility.
During the past decade, the FERC has dramatically transformed the natural gas
industry through a series of generic orders promoting competition in the
industry. As part of that transformation, the interstate pipelines that serve
the utility have been required to:

 .  Unbundle, or separate, their transportation and gas supply services; and

 .  Provide a separate transportation service on a nondiscriminatory basis for
   the gas that is supplied by numerous gas producers or other third parties.

The FERC is considering further revisions to its rules, including the following:

 .  Its policies governing secondary market transactions for use of pipeline
   capacity; and

 .  Revisions that would 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 whether revisions will be adopted or how they 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 September 30, 1999, approximately $105.8 million of those costs
had been incurred and were being recovered primarily from the utility's
customers under rates charged for gas sales. Going forward, AGLC's remaining
costs will be recovered from certificated marketers.

The largest portion of the transition costs the utility must pay consists of gas
supply realignment costs that Southern Natural Gas Company ("Southern") and
Tennessee Gas Pipeline Company ("Tennessee") bill the utility. The utility and
other parties have entered restructuring settlements with Southern and Tennessee
that resolve all transition cost issues for those pipelines.

Under the Southern settlement, the utility's share of Southern's transition
costs is approximately $89.7 million, of which the utility incurred $87.6
million as of September 30, 1999. Under the Tennessee settlement, the utility's
share of Tennessee's transition costs was approximately $14.7 million, all of
which had been incurred by September 30, 1999.

Southern filed a general rate case on September 1, 1999.  Its proposed rates
would represent a 10% increase (about $15 million per year) under AGLC's
existing contracts in firm interstate pipeline charges. These rates would become
effective March 1, 2000, subject to refund unless the FERC should accept an
offer of settlement between Southern and its customers.  Such a settlement is
currently under discussion.

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 twelve 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 used the following process for the estimates:
First, AGLC eliminated the sites where it was believed that no cleanup or
further investigation was likely to be necessary. Second, AGLC estimated its
likely future cost of investigation and cleanup at each of the remaining sites.
Third, for some sites, AGLC estimated its likely "share" of the costs. AGLC
developed its estimate based on any agreements for cost sharing it has, the
legal principles for sharing costs, its evaluation of other entities' ability to
pay, and other similar factors.

Using the above process, AGLC currently estimates that its total future cost of
investigating and cleaning up 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.
Consequently, AGLC has recorded the lower end of the range, or $102.4 million,
as a liability and a corresponding regulatory asset as of September 30, 1999.
AGLC does not believe that any single number within the range constitutes a
"better" estimate because its actual future investigation and cleanup costs will
be affected by a number of contingencies that cannot be quantified at this time.
During fiscal 1999, the asset increased $78.7 million and was reduced by
amortization of $6.1 million resulting in an asset of $150.2 million.

As of September 30, 1998, AGLC had recorded a liability of $47.0 million. During
fiscal 1999, the liability increased by $78.7 million and payments of $23.3
million were made. The net increase in the liability was $55.4 million resulting
in a liability of $102.4 million as of September 30, 1999. The net increase in
the liability was based on revised estimates of future costs, which resulted in
a corresponding increase in the unrecovered environmental response cost asset.

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. During fiscal 1999, AGLC
recovered $6.1 million through its environmental response recovery rider.

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 fiscal 1999.

Competition

Utility

The utility competes with alternative energy suppliers to distribute natural gas
to large commercial and industrial customers. Those customers can switch to
alternative fuels, including propane, fuel and waste oils, electricity and, in
some cases, combustible wood by-products. AGLC also competes to distribute gas
to large commercial and industrial customers who seek to bypass AGLC's
distribution system.

Pursuant to the GPSC's rate case order of June 30, 1998, AGLC has been able to
price distribution services to large commercial and industrial customers in one
of three ways:

 .  GPSC approved rates in AGLC's tariff;

 .  Negotiated rates if an existing rate is not priced competitively with a
   customer's competitive alternative fuel; or

                                       6
<PAGE>

 .  Special contracts approved by the GPSC.

Additionally, interruptible customers have the option of purchasing delivery
service directly from certificated marketers, who are authorized to use capacity
on AGLC's distribution system that is allocated to the certificated marketers
for firm residential and small commercial customers, whenever such capacity is
not being used for firm customers.

Non-utility

AGL Resources engages in several competitive, energy-related businesses,
including gas supply services, wholesale and retail propane sales, customer care
services, and the sale of energy-related products and services for residential,
commercial, and industrial customers throughout the Southeast. (See
Organizational Structure section under Business Overview.)

Unlike the utility, the non-utility businesses are not regulated. The non-
utility businesses typically face competition from other companies in the same
or similar businesses.

SouthStar competes with other energy marketers, including certificated marketers
in Georgia, to provide natural gas and related services to customers in Georgia
and the Southeast. SouthStar began marketing natural gas to all customers in
Georgia during the first quarter of fiscal 1999. Marketing efforts during the
transition to competition in Georgia consisted of advertising and promotional
campaigns. As of October 1, 1999, SouthStar had the largest market share among
approximately 15 certificated and active marketers in Georgia.

Utilipro competes with other customer care service providers throughout the
United States and Canada. Utilipro anticipates that the number of competitors
will increase as energy markets in the United States and Canada become
deregulated.

July 23, 1999


Mr. Charles W. Bass
1675 Redbourne Drive
Dunwoody, GA  30350

Dear Charlie:

     The purpose of this letter agreement (the "Agreement") is to set out the
terms and conditions of your provision of consulting services to AGL Resources
Inc. (the "Company").

1.  Term.  The term of the Agreement shall be two years, beginning on August 1,
    ----
    1999 (the "Effective Date") and continuing until July 31, 2001, unless
    terminated earlier as provided in Section 13 hereof.

2.  Consulting Services.  During the term of the Agreement, you will provide
    -------------------
    consulting services to the Company at such times and in such capacities as
    may reasonably be requested by the Chief Executive Officer of the Company.
    In addition, during the Term, you will serve as a member of the board of
    directors or equivalent governing body of certain subsidiaries and/or
    affiliated entities of the Company, as requested by the Chief Executive
    Officer. The Company anticipates that your consulting services will require
    approximately 400 hours of your time each year during the Term.

3.  Compensation.  The Company will pay you an annual consulting fee of
    ------------
    $80,000.00 for each year of the Term during which you provide consulting
    services to the Company under this Agreement. The consulting fee will be
    paid to you on a monthly basis in arrears as of the last day of each month.

4.  Business Expenses.  The Company will reimburse you for any reasonable
    -----------------
    business expenses that you incur while performing consulting services under
    this Agreement, subject to your compliance with Company policies and
    procedures regarding documentation for reimbursement of business expenses.

5.  Independent Contractor.  You will provide consulting services under this
    ----------------------
    Agreement as an independent contractor to the Company. That means that, in
    your capacity as a consultant under this Agreement, you will not be entitled
    to participate in any employee benefit plans, coverages, payroll policies
    (such as vacation, holiday or sick pay) or other programs of the Company
    during the Term. In addition, you are responsible for reporting all income
    and compensation provided to you by the Company under this Agreement, and
<PAGE>

    you are responsible for paying all social security or federal, state or
    local income taxes, as well as any self-employment taxes, arising therefrom.
    You will also be required to provide your own workers' compensation coverage
    if such coverage is required by applicable law. As an independent
    contractor, you will have control over the method, manner and means of
    providing consulting services under this Agreement.

6.  Covenant Not to Compete.  You hereby covenant and agree that, during a
    -----------------------
    period beginning on the Effective Date and ending one (1) year after the
    termination of this Agreement, you will not directly or indirectly, on your
    own behalf or on behalf of any person or entity, compete with the Company by
    performing activities or duties substantially similar or related to the
    functions, activities or duties performed by you for the Company for any
    business entity engaged in direct competition with the Company. A business
    entity shall be considered to be "in direct competition" with the Company if
    it is engaged in producing, manufacturing, distributing, marketing, selling,
    servicing or repairing products similar to products produced, manufactured,
    distributed, marketed, sold, serviced or repaired by the Company, including
    (but not limited to) any type of production or distribution of any energy
    source, whether by cultivation of natural resources or by technology. This
    restriction shall apply only to a restricted territory within a 100-mile
    radius of any locations, sites or facilities in which the Company (including
    its affiliates) maintains offices, operations or service contracts or has
    provided services during the Term of this Agreement, or with regard to the
    1-year noncompetition period following the termination of this Agreement,
    the 1-year period immediately preceding the date of termination of this
    Agreement. Notwithstanding the above, this provision shall apply to any
    business entity involved in the production, manufacture, distribution,
    marketing, sales, service or repair of products or services in the propane
    industry only for such portion of the 1-year noncompetition period following
    termination of this Agreement as the Company (or any of its affiliates,
    related entities or joint ventures) owns or operates all or part of a
    propane business entity. To the extent that you have concerns about any
    employment or engagement opportunities that you may have and the limitations
    thereon presented by this noncompetition provision, the Company agrees to
    discuss those opportunities with you and provide a prompt response to you as
    to whether the Company will consider such employment or engagement (or any
    part thereof) to be a violation of this provision.

7.  Nondisclosure of Trade Secrets and Confidential Information.  As a
    -----------------------------------------------------------
    consultant to the Company, you acknowledge and agree that during the term of
    this Agreement, you will have access to trade secrets and other confidential
    information unique to the business of the Company and that the disclosure or
    unauthorized use of such trade secrets or confidential information by you
    would injure the Company's business. Therefore, you agree that you will not,
    at any time during the term of this Agreement and for a period of one (1)
    year thereafter, use, reveal or divulge any trade secrets or any other
    confidential information which, while not trade secrets or information
    unique to the Company's business, is confidential and constitutes a valuable
    asset of the Company by reason of the material investment of the Company's
    time and money in the production of such
<PAGE>

    information. You also agree that you will not use, reveal or divulge any
    general confidential or customer-related information.

8.  Nonsolicitation.  Due to your extensive knowledge of the specifics of the
    ---------------
    Company's business, and its customers and clients, you agree that during the
    term of this Agreement and for a period of one (1) year thereafter, you will
    not, without the prior written consent of the Company, either directly or
    indirectly, on your own behalf or in the service or on behalf of others,
    solicit, divert or appropriate, or attempt to solicit, divert or
    appropriate, to any business that competes with the Company's business, any
    person or entity who transacted business with the Company during the Term of
    this Agreement or during the year preceding the Effective Date of this
    Agreement. The persons or entities referred to in the immediately preceding
    sentence shall include any and all persons or entities with respect to whom
    you have (i) had direct contact, (ii) been directly involved in the
    Company's marketing or sales strategies directed to such persons or
    entities, or (iii) been privy to the Company's marketing or sales strategies
    directed to such persons or entities. For purposes of this provision, the
    Company's business shall include any and all aspects of producing,
    manufacturing, distributing, marketing, selling, servicing or repairing
    products similar to products produced, manufactured, distributed, marketed,
    sold, serviced or repaired by the Company and/or any of its affiliates,
    including (but not limited to) any type of production or distribution of any
    energy source, whether by cultivation of natural resources or by technology.
    You also agree that during the term of this Agreement and for a period of
    one (1) year thereafter, you will not, either directly or indirectly, on
    your own behalf or in the service or on behalf of others solicit, divert or
    hire away, or attempt to solicit, divert or hire away to any business that
    competes with Company's business any person employed by the Company, or any
    person employed by the Company at any time during the Term of this
    Agreement.

9.  Remedies.  In addition to any legal or equitable remedies available to the
    --------
    Company, including injunctive relief, the Employee agrees and acknowledges
    that if he violates any provision of this Agreement, the Company may
    immediately cease any and all payments payable hereunder.

10. Invalidity of Any Provision.  It is the intent of the parties hereto that
    ---------------------------
    the provisions of this Agreement will be enforced to the fullest extent
    permissible under the laws and public policies of each state and
    jurisdiction in which such enforcement is sought, but that the
    unenforceability (or the modification to conform with such laws or public
    policies) of any provision hereof shall not render unenforceable or impair
    the remainder of this Agreement which shall be deemed amended to delete or
    modify, as necessary, the invalid or unenforceable provisions.

11. Governing Law/Survival/Binding Effect.  This Agreement will be governed by
    -------------------------------------
    the laws of the State of Georgia. The provisions of paragraphs 6, 7, 8, 9
    and 10 will survive the termination of this Agreement. The Company may
    assign its rights and/or obligations under this Agreement. You may not
    assign your rights and/or obligations under this Agreement; however, you may
    assign your rights and/or obligations under this Agreement to any business
    or entity in which you and/or your spouse own a controlling interest and
    which business or
<PAGE>

    entity affirmatively assumes your obligations under this Agreement,
    including the obligation that you will be personally performing the services
    hereunder.

12. Amendment/Entire Agreement.  Once you sign this Agreement, it may not be
    --------------------------
    amended or modified except by a writing executed by you and the Company that
    specifically refers to this Agreement and expressly states that it is
    intended to amend this Agreement. You agree that this Agreement, in
    conjunction with your Early Retirement Agreement with the Company, contains
    the entire agreement between you and the Company regarding your provision of
    consulting services to the Company.

13. Termination of Agreement.  This Agreement may be terminated by either
    ------------------------
    party upon thirty (30) days' prior written notice to the other party;
    provided, however, that upon and after a "change in control" of the Company
    (as defined in the Company's Long-Term Incentive Plan), the Agreement may
    not be terminated by the Company prior to the end of its Term.

    Please sign this Agreement to acknowledge your understanding and acceptance
its terms and conditions and return it to the Company.  You should keep a copy
of this letter for your records.

                                       Very truly yours,

                                       /s/ Walter M. Higgins

                                       Walter M. Higgins
                                       Chief Executive Officer

Resources Inc. Long-Term Incentive Plan (1999) (the "LTIP") to further the
growth and development of the Company.  The LTIP encourages Eligible Employees
of the Company and its Related Companies to obtain a proprietary interest in the
Company by owning its stock.  The LTIP also will provide the Eligible Employees
with an added incentive to continue in the employ of the Company or a Related
Company and will stimulate their efforts in promoting the growth, efficiency and

Reload Options.  The Company intends that ISOs granted under the LTIP qualify as
incentive stock options under Code (S)422.  NQSOs are options that do not
qualify as ISOs and are subject to taxation under Code (S)83.  Awards of
Restricted Stock and/or Performance Units are subject to taxation under Code
(S)83.

LTIP at the February 5, 1999 annual meeting of shareholders.  The LTIP is
effective as of January 1, 1999 (the "Effective Date").  Unless terminated by
the Company, the LTIP will remain in effect until the tenth anniversary of the
earlier of the date the Board adopted the LTIP or the shareholders approved the
LTIP.   If the LTIP is terminated earlier, then it will remain in effect as long
as any Awards are outstanding.

          -----------------------------------------
administration of the LTIP is subject to the provisions of this plan document.

     3.1  Administration.  The Nominating and Compensation Committee of the
          --------------
Board of Directors of the Company (the "Committee") will control and manage the
operation and administration of the LTIP.

          (a) The Committee may make one or more Awards under the LTIP to an
     Eligible Employee, who will become a Participant in the LTIP.   In
     addition, the Committee may make one or more Awards (other than grants of
     ISOs) to an individual who has accepted an offer of employment from the
     Company or one of its Related Companies but who has not yet become an
     Eligible Employee; provided, that the Committee will subject such Award(s)
     to appropriate restrictions in the event that such individual does not
     become an Eligible Employee.  The Committee will decide to whom and when to
     grant an Award, the type of Award that it will grant and the number of
     shares of Common Stock covered by the Award.  The Committee also will
     decide the terms, conditions, performance criteria, restrictions and other
     provisions of the Award. The Committee may grant a single Award or an Award
     in combination with another Award(s) to a Participant.  In making Award
     decisions, the Committee may take into account the nature of services
     rendered by the Eligible Employee, the Eligible Employee's present and
     potential contribution to the Company's success and such other factors as
     the Committee, in its sole discretion, deems relevant.

          (b) In accordance with Section 5 of the LTIP, the Committee will
     decide whether and to what extent Awards under the LTIP will be structured
     to conform with Code (S)162(m) requirements applicable to performance-based
     compensation.  The Committee may take any action, establish any procedures
     and impose any restrictions that it finds necessary or appropriate to
     conform with Code (S)162(m).  If every member of the Committee does not
     meet the definition of "outside director" as defined in Code (S)162(m), the
     Committee will form a subcommittee of those members who do meet that
     definition,

                                       4
<PAGE>

     and that subcommittee will have all authority and discretion to act as the
     Committee to make Awards that conform with Code (S)162(m).

          (c) The Committee will interpret the LTIP, establish and rescind any
     rules and regulations relating to the LTIP, decide the terms and provisions
     of any Agreements made under the LTIP, and determine how to administer the
     LTIP.  The Committee also will decide administrative methods for the
     exercise of Stock Options.  Each Committee decision will be final,
     conclusive and binding on all parties.

          (d) The Committee will act by a majority of its then members at a
     meeting of the Committee or by unanimous written consent.  The Committee
     will keep adequate records concerning the LTIP and the Committee's
     proceedings and acts in such form and detail as the Committee may decide.

     3.2  Delegation by Committee.  Unless prohibited by applicable law or the
          -----------------------
applicable rules of a stock exchange, the Committee may allocate all or some of
its responsibilities and powers to any one or more of its members.  The
Committee also may delegate all or some of its responsibilities and powers to
any person or persons it selects.  The Committee may revoke any such allocation
or delegation at any time.  The Committee delegates to the Company's Corporate
Secretary the authority to document any and all grants and awards made by the
Committee under the LTIP.

     3.3  Information to be Furnished to Committee.  In order for the Committee
          ----------------------------------------
to discharge its duties, it may require the Company, its Related Companies,
Participants and other persons entitled to benefits under the Plan to provide it
with certain data and information.

     3.4  Indemnification.  In addition to such other rights of indemnification
          ---------------

                        PERFORMANCE-BASED COMPENSATION

     5.1  Performance-Based Compensation.  The Committee may, in its sole
          ------------------------------
discretion, make Awards to Participants intended to comply with the
"performance-based" compensation requirements of Code (S)162(m).  Vesting of
such Awards will be determined based on the attainment of objective written
performance goals for a performance period.  The performance

                                       6
<PAGE>

goal will state, in terms of an objective formula or standard, the method for
computing the vesting of the Award if the goal is attained. The performance
goals must be established by the Committee in writing no later than 90 days
after the commencement of the performance period or, if less, the number of days
which is equal to 25% of the relevant performance period. Performance goals will
be based on the attainment of one or more performance measures. To the degree
consistent with Code (S)162(m), the performance goals may be calculated without
regard to extraordinary items.

     5.2  Performance Measures.  Performance measures may include the following:
          --------------------
(i) consolidated earnings before or after taxes (including earnings before
interest, taxes, depreciation and amortization); (ii) net income; (iii)

profitability of an identifiable business unit or product; (xii) maintenance or
improvement of profit margins; (xiii) stock price; (xiv) market share; (xv)
revenues or sales; (xvi) costs; (xvii) cash flow; (xviii) working capital; (xix)
return on assets; or (xx) gross or net profit. Performance measures may relate
to the Company one or more of its subsidiaries, one or more of its divisions or
units or any combination of the foregoing, and may be applied on an absolute
basis or be relative to one or more peer group companies or indices, or any
combination thereof, all as the Committee determines.

     5.3  Additional Requirements.  For Awards under this Section 5 to
          -----------------------
constitute performance-based compensation under Code (S)162(m), the material
terms of the performance goal attributable to such Award must be disclosed to
and subsequently approved by the Company's shareholders before any compensation
attributable to such Award is paid.  The Committee must certify in writing prior
to the payment of performance-based compensation attributable to Awards of
Restricted Stock and/or Performance Units that the performance goals applicable
to such Awards, as well as any other material terms applicable to such Awards,
were satisfied.  Such written certification may include the approved minutes of
the Committee meeting in which the certification is made.

     6.5  Expiration Date.
          ---------------

          (a)  Original Expiration Date.  Unless the Committee specifies
               ------------------------
     otherwise in the Stock Option Agreement, subject to section (b) below, the
     term of a Stock Option granted under the LTIP begins on the date of grant
     and ends ten years after the date of grant (or five years from the date of
     grant for an ISO optionee who owns more than ten percent of the voting
     power of all classes of stock of either the Company or any "parent" or
     "subsidiary" of the Company as defined in Code (S)424).

                      ----------
                      termination of employment with the Company and all Related
                      Companies due to disability (as determined by the
                      Committee in its sole discretion);

               (iv)   Retirement.  The one-year anniversary of the Optionee's

                      Resources Inc. Retirement Plan or any other retirement
                      plan approved by the Board for that purpose (provided,
                      that if all or part of an ISO is not exercised within
                      three months after the Optionee's retirement, the
                      unexercised portion thereof will automatically become an
                      NQSO for the remainder of the one-year period); or

               (v)    Termination of Employment.  The date of the Optionee's
                      -------------------------

                      Companies for any reason other than death, disability or
                      retirement (as described above); provided, that if the
                      Optionee's termination of employment is due to a layoff,
                      office or operation closing, or other involuntary
                      severance by the Company or Related Company (except for
                      performance reasons), then the date sixty (60) days
                      following the date of the Optionee's termination of
                      employment.

                                       9
<PAGE>

     The Committee will always have the authority and discretion to extend the
Expiration Date of any Stock Option as long as the extended Expiration Date is
not later than the Original Expiration Date.  If the Committee extends the
Expiration Date of an ISO beyond any legal period for ISO tax treatment, then
the ISO will automatically convert to an NQSO for the remainder of the extended
exercise period.

     6.6  Terms of Stock Option Exercise.  Unless the Committee specifies
          ------------------------------
otherwise in the Stock Option Agreement, an Optionee may exercise a Stock Option
for less than the full number of shares of Common Stock subject to the Stock
Option.  However, such exercise may not be made for less than 100 shares or the
total remaining shares subject to the Stock Option.  The Committee may in its
discretion specify other Stock Option terms, including restrictions on frequency
of exercise and periods during which Stock Options may not be exercised.

     6.7  Payment of Exercise Price.  The Optionee must pay the full Exercise
          -------------------------
Price for shares of Common Stock purchased upon the exercise of any Stock Option
at the time of such exercise by one of the following forms of payment:

          (a)  cash;

          (b)  by tendering unrestricted shares of Common Stock which have a
     Fair Market Value equal to the Exercise Price. The Optionee must have held
     the tendered shares of Common Stock for at least six months before their
     tender. The Optionee may tender shares of Common Stock either by
     attestation or by the delivery of a certificate or certificates for shares
     duly endorsed for transfer to the Company, and if required, with medallion
     level signature guarantee by a member firm of a national stock exchange, by
     a national or state bank, or by the Company's credit union (or guaranteed
     or notarized in such other manner as the Committee may require);

          (c)  broker-assisted cashless exercise; or

          (d)  any combination of the above forms or any other form of payment
     permitted by the Committee.

     6.8  Reload Options.  When the Committee grants a Stock Option, it will
          --------------
designate in the Stock Option Agreement whether a Reload Option accompanies such
Stock Option and any limitations that will apply to the granting of the Reload
Option or the number of successive Reload Options.  The Committee, in its
discretion, may grant one or more successive Reload Options to an Optionee who
pays all or a portion of the Exercise Price of a Stock Option with shares of
Common Stock.  Notwithstanding the terms of any Stock Option, the Committee will
grant Reload Options only to Participants who are actively employed by the
Company or a Related Company at the time the grant is to be made.  If the
Committee has designated a Stock Option as having an accompanying Reload Option,
the Committee will grant a Reload Option for the same number of shares as is
tendered in payment of the Exercise Price (but not for shares tendered for tax
or other withholding obligations) upon exercise of the Stock Option.  The Reload
Option will have the same terms and conditions as the related original Stock
Option, including the expiration date of the original Stock Option, except that
(i) the Exercise Price for a Reload Option will be the Fair Market Value of the
Common Stock as of the date of grant of

                                       10
<PAGE>

such Reload Option, and (ii) the Reload Option will become fully exercisable six
months after its date of grant (except as may be limited by ISO limitations).

     6.9   Transferability.  Unless the Committee specifies otherwise in the
           ---------------
Stock Option Agreement, an Optionee may transfer Stock Options under the LTIP
only by will or by the laws of descent and distribution.  After the death of an
Optionee, only the executor or administrator of the Optionee's estate may
exercise an outstanding Stock Option.

     6.10  Rights as a Shareholder.  An Optionee will first have rights as a
           -----------------------
shareholder of the Company with respect to shares of Common Stock covered by a
Stock Option only when the Optionee has paid the Exercise Price in full and the
shares have been issued to the Optionee.

     Restricted Stock; and

           (d)  the date as of which the Committee awarded the Restricted Stock.

     7.2   Maximum Award Per Year.  Subject to adjustment in accordance with
           ----------------------
Section 9 of the LTIP, no more than 50,000 shares of Restricted Stock may be
awarded during a calendar year to any one Eligible Employee.

     7.3   Vesting.  Restricted Stock will become vested and nonforfeitable in
           -------
accordance with the vesting schedule and/or vesting requirements set forth in
the applicable Restricted Stock Agreement.  The Committee may determine, in
accordance with Section 5 of the LTIP, whether such vesting schedule and/or
vesting requirements will conform with the requirements applicable to
performance-based compensation under Code (S)162(m).  Restricted Stock will
become immediately vested and nonforfeitable upon a Change of Control of the
Company.  In addition, the Committee will always have the authority to
accelerate vesting of any Restricted Stock awarded under this LTIP.

     7.4   Termination of Employment.  Unless the Committee decides otherwise,
           -------------------------
all shares of Restricted Stock which remain subject to restriction upon the

Plan or any other retirement plan approved by the Board for that purpose) will
be forfeited as of the date of such termination of employment.

<PAGE>

     7.5  Delivery of Restricted Stock.  The Company will issue the shares of
          ----------------------------

in uncertificated form in a restricted account.

     7.6  Transferability.  Unless the Committee specifies otherwise in the
          ---------------
Restricted Stock Agreement, a Recipient may not sell, exchange, transfer,
pledge, hypothecate or otherwise dispose of shares of Restricted Stock awarded
under this LTIP while such shares are still subject to restriction.

     7.7  Effect of Restricted Stock Award.  Upon issuance of the shares of the
          --------------------------------
Restricted Stock, the Recipient will have immediate rights of ownership in the
shares of Restricted Stock, including the right to vote the shares and the right
to receive dividends with respect to the shares.

                               PERFORMANCE UNITS

     8.1  Performance Unit Agreement.  When the Committee awards Performance

          (d)  the date as of which the Committee awarded the Performance Units.

     8.2  Maximum Award Per Year.  Subject to adjustment in accordance with
          ----------------------

during a calendar year to any one Eligible Employee.

     8.3  Performance Unit Account.  When the Committee awards Performance Units
          ------------------------
under the LTIP, the Company will establish a bookkeeping account for the
Recipient which will accurately reflect the number of Performance Units awarded
to the Recipient.

     8.4  Dividends.  On each date on which a dividend is distributed by the
          ---------
Company on shares of Common Stock (whether paid in cash, Common Stock or other
property), the Recipient's Performance Unit account will be credited with an
additional whole or fractional number of Performance Units.  The number of
additional Performance Units to be credited will be determined by dividing the
product of the dividend value times the number of Performance Units standing in
the Recipient's account on the dividend record date by the Fair Market Value of
the Common Stock on the date of the distribution of the dividend (i.e., dividend
amount x

                                       12
<PAGE>

number of whole and fractional Performance Units as of the dividend record
date / Fair Market Value of Common Stock as of dividend distribution date).
Accounts will be maintained and determinations will be calculated to three
decimal places.

     8.5  Vesting.  Performance Units will become vested and nonforfeitable in
          -------
accordance with the vesting schedule and/or vesting requirements set forth in
the applicable Performance Unit Agreement.  The Committee may determine, in
accordance with Section 5 of the LTIP, whether such vesting schedule and/or
vesting requirements will conform with the requirements applicable to
performance-based compensation under Code (S)162(m).  Performance Units will
become immediately vested and nonforfeitable upon a Change of Control of the
Company at the "target level," as prorated on a daily basis based on the
completed portion of any applicable performance period as of the date of the
Change of Control.  In addition, the Committee will always have the authority to
accelerate vesting of any Performance Units awarded under this LTIP.

     8.6  Termination of Employment.  Unless otherwise specified by the
          -------------------------
Committee, unvested Performance Units will be forfeited as of the date of the
Recipient's termination of employment for any reason (including death,
disability or retirement under the terms of the AGL Resources Inc. Retirement
Plan or any other retirement plan approved by the Board for that purpose).

     8.7  Delivery of Common Stock.  Upon vesting, Performance Units will be
          ------------------------
converted into Common Stock and the Common Stock will be issued to the Recipient
within a reasonable period of time.  Upon issuance of the Common Stock to the
Recipient, the Recipient of a Performance Unit Award  will have immediate rights
of ownership in the shares of Common Stock, including the right to vote the
shares and the right to receive dividends with respect to the shares.

     8.8  Transferability.  A Recipient may not sell, exchange, transfer,
          ---------------
pledge, hypothecate or otherwise dispose of Performance Units awarded under this
LTIP.

          ----------------------
discretion, to waive any or all restrictions with respect to an award of
Performance Units.

                      kind of shares of Common Stock subject to outstanding
                      Awards;

               (iii)  the Committee will take action to adjust the Exercise
                      Price of outstanding Stock Options; and

               (iv)   the Committee will make any other equitable adjustments.

     Only whole shares of Common Stock will be issued in making the above
     adjustments. Further, the number of shares available under the LTIP or the
     number of shares of Common Stock subject to any outstanding Awards will be
     the next lower number of shares, so that fractions are rounded downward.
     Any adjustment to or assumption of ISOs under this Section will be made in
     accordance with Code (S)424.  If the Company issues any rights or warrants
     to subscribe for additional shares pro rata to holders of outstanding
     shares of the class or classes of stock then set aside for the LTIP, then
     each Optionee will be entitled to the same rights or warrants on the same
     basis as holders of outstanding shares with respect to such portion of the
     Optionee's Stock Option as is exercised on or prior to the record date for
     determining shareholders entitled to receive or exercise such rights or
     warrants.

          (b)  Reorganization. If the Company is part of any reorganization
               --------------
     involving merger, consolidation, acquisition of the stock or acquisition of
     the assets of the Company which requires shareholder approval but does not
     constitute a Change of Control, the Committee, in its discretion, may
     decide that:

               (i)    any or all outstanding Stock Options granted under the
                      LTIP will pertain to and apply, with appropriate
                      adjustment as determined by the Committee, to the
                      securities of the resulting corporation to which a holder
                      of the number of shares of the Common Stock subject to
                      such Stock Option would have been entitled;

               (ii)   any or all outstanding Stock Options granted under the
                      LTIP will become immediately fully exercisable (to the
                      extent permitted under federal or state securities laws);

               (iii)  any or all outstanding Stock Options granted under the
                      LTIP will become immediately fully exercisable (to the
                      extent permitted under federal or state securities laws)
                      and will be terminated after giving at least 30 days'
                      notice to the Participants to whom such Stock Options have
                      been granted; and/or

               (iv)   any or all awards of Restricted Stock and/or Performance
                      Units hereunder will become immediately fully vested and
                      nonforfeitable.

          (c)  Limits on Adjustments.  Any issuance by the Company of stock of
               ---------------------
     any class other than the Common Stock, or securities convertible into
     shares of stock of any class, will not affect, and no adjustment by reason
     thereof will be made with respect to, the number or price of shares of the
     Common Stock subject to any Stock Option, except as specifically provided
     otherwise in this LTIP.  The grant of Awards under the LTIP will not affect
     in any way the right or authority of the Company to make adjustments,
     reclassifications, reorganizations or changes of its capital or business
     structure or to merge, consolidate or dissolve, or to liquidate, sell or
     transfer all or any part of its business or assets.  All adjustments the
     Committee makes under this LTIP will be conclusive.

     9.2  Compliance with Other Laws and Regulations.  Distribution of shares of
          ------------------------------------------
Common Stock under the LTIP will be subject to the following:

          (a)  Notwithstanding any other provision of the LTIP, the Company will
     not be required to issue any shares of Common Stock under the LTIP unless
     such issuance complies with all applicable laws (including, without
     limitation, the requirements of the 1933 Act and Section 16 of the 1934
     Act) and the applicable requirements of any securities exchange or similar
     entity.  For Reporting Persons, the Company believes that the LTIP and all
     transactions under the LTIP comply with all applicable conditions of Rule
     16b-3 under the 1934 Act.  If any provision of the LTIP, or action by the
     Committee, fails to so comply, then the Committee will declare such
     provision or action null and void ab initio.

          (b)  When the LTIP provides for issuance of Common Stock, the Company
     may issue shares of Common Stock on a noncertificated basis as long as it
     is not prohibited by applicable law or the applicable rules of any stock
     exchange.

          (c)  The Company may require a Participant to submit evidence that the
     Participant is acquiring shares of Common Stock for investment purposes.

     9.3  Tax Withholding.  The Participant must pay to the Company an amount
          ---------------
necessary to cover all applicable income tax and other withholdings before the
Company will issue Common Stock under the LTIP.  The Participant may satisfy the
withholding requirements by any one or combination of the following methods:

          (a)  cash; or

          (b)  withholding shares of Common Stock which are otherwise issuable
     as part of the Award.

     9.4  Limitation of Implied Rights.  The LTIP is not a contract of
          ----------------------------
employment.  An Eligible Employee selected as a Participant will not have the
right to be retained as an employee of the Company or any Related Company and
will not have any right or claim under the LTIP, unless such right or claim has
specifically accrued under the terms of the LTIP.

     9.5  Conditions of Participation in the LTIP.  When the Committee makes an
          ---------------------------------------
Award, it

                                       15
<PAGE>

will require a Participant to enter into an Agreement in a form specified by the
Committee, agreeing to the terms and conditions of the Award and to such
additional terms and conditions, not inconsistent with the terms and conditions
of the LTIP, as the Committee may, in its sole discretion, prescribe. If there
is a conflict between any provision of an Agreement and the LTIP, the LTIP will
control.

     9.6   Evidence.  Anyone required to give evidence under the LTIP may give
           --------
such evidence by certificate, affidavit, document or other information which the
person acting on the evidence considers pertinent, reliable and signed, made or
presented by the proper party or parties.

     9.7   Amendment and Termination of the LTIP and Agreements.  The Board may
           ----------------------------------------------------
amend or terminate the LTIP at any time.  No such amendment or termination will
adversely affect, in any way, the rights of individuals who have outstanding
Awards unless such individuals consent to such amendment or termination.  The
Committee may amend any Agreement which it previously has authorized under the
LTIP if the amended Agreement is signed by the Company and the applicable
Participant.

     9.8   Action by Company or Related Company.  The board of directors of the
           ------------------------------------
Company or any Related Company will take any action required or permitted to be
taken by resolution.

     9.9   Gender and Number; Headings.  Words in any gender will include any
           ---------------------------
other gender, words in the singular will include the plural and the plural will
include the singular.  The headings in this LTIP are for convenience of
reference.  Headings are not a part of the LTIP and will not be considered in
the construction of the LTIP.

     9.10  Legal References.  Any reference in this LTIP to a provision of law
           ----------------
which is later revised, modified, finalized or redesignated, will automatically
be considered a reference to such revised, modified, finalized or redesignated
provision of law.

     9.11  Notices.  In order for a Participant or other individual to give
           -------
notice or other communication to the Committee, the notice or other
communication will be in the form specified by the Committee and delivered to
the location designated by the Committee in its sole discretion.

     9.12  Governing Law.  The LTIP is governed by and will be construed in
           -------------
accordance with the laws of the State of Georgia.

                           NONQUALIFIED SAVINGS PLAN

                                                                    July 1, 1998

                           NONQUALIFIED SAVINGS PLAN


         Effective as of the 1st day of July, 1998, AGL Resources Inc., a
corporation duly organized and existing under the laws of the State of Georgia
(the "Controlling Company"), hereby amends and restates the AGL Resources Inc.
Nonqualified Savings Plan (the "Plan").  The Plan was originally established as
of the 1st day of July, 1995.


                             STATEMENT OF PURPOSE
                             --------------------


         A.   The primary purpose of the Plan is to recognize the contributions
made to the Controlling Company and its participating affiliates by certain
employees and to reward those contributions by providing eligible employees with
an opportunity to accumulate savings for their future security.

         B.   The Plan is intended to be an unfunded nonqualified deferred
compensation plan maintained by the Controlling Company primarily for the
purpose of providing deferred compensation for a select group of management or
highly compensated employees (within the meaning of (S)(S)201(2), 301(a)(3),
401(a)(1) and 4021(b)(6) of the Employee Retirement Income Security Act of 1974,
as amended), and shall be construed in all respects in accordance with such
intended purposes.

         C.   Any trust fund established to maintain and invest the amounts
contributed to the Plan shall be established under a trust agreement which meets
the requirements of a "rabbi trust," pursuant to guidelines issued by the
Internal Revenue Service (the "IRS").

         D.   Regardless of the establishment of a trust fund, all assets of the
Plan shall remain assets of the Controlling Company and shall be subject to the
general creditors of the Controlling Company.  Participants and Beneficiaries
shall have only the rights of unsecured creditors with respect to any assets of
the Plan.


                            STATEMENT OF AGREEMENT

         In order to amend and restate the Plan with the purposes and goals as
hereinabove described, the Controlling Company hereby sets forth the terms and
provisions of the amended and restated Plan as follows:

Board which shall act on behalf of the Controlling Company to administer the

           ---------
and (ii) any company, person or organization which, on such date, (A) is a

Participating Company to the Plan at the election of Participants, all pursuant
to the terms of (S)3.1(a).

     1.7   Beneficiary shall mean the person(s) designated in accordance with
           -----------
(S)7.4 to receive any death benefits that may be payable under the Plan upon the

in Service, an Employee absent from work due to a Maternity or Paternity Leave
shall be credited with (i) the number of Hours of Service with which he normally
would have been credited but for the Maternity or Paternity Leave, or (ii) if
the Administrative Committee is unable to determine the hours described in (i),
8 Hours of Service for each day of absence included in the Maternity or
Paternity Leave; provided, the maximum number of Hours of Service credited for
purposes of this Section shall not exceed 501 hours. Hours of Service so
credited shall be applied only to the year in which the Maternity or Paternity
Leave begins, unless such Hours of Service are not required to prevent the

or Paternity Leave and (B) of the number of days he was absent due to the
Maternity or Paternity Leave. The Administrative Committee shall prescribe
uniform and nondiscriminatory procedures by which to make the above

Participant may elect to reduce his Compensation for any period by a maximum of
50 percent; provided, that the total of the Active Participant's Before-Tax

as determined below. The Administrative Committee, in its sole discretion, shall
prescribe the form of all Deferral Elections and may prescribe such
nondiscriminatory terms and conditions governing the use of the Deferral
Elections as it deems appropriate. Subject to any modifications, additions or
exceptions which the Administrative Committee, in its sole discretion, deems
necessary, appropriate or helpful, the following terms shall apply to Deferral

     Election with a Participating Company shall be effective for the first
     payroll period which ends after the Deferral Election is made and after the
     effective date specified for such Deferral Election. If an Active
     Participant fails to submit an initial Deferral Election in a timely
     manner, he shall be deemed to have elected a deferral of zero percent.

               (2)  Term.  Each Active Participant's Deferral Election with a
                    ----
     Participating Company shall remain in effect in accordance with its
     original terms until the earlier of (A) the date the Active Participant
     ceases to be an Employee of all Participating Companies, (B) the date the
     Active Participant revokes or modifies such Deferral Election pursuant to
     the terms of subsection (b)(3) hereof, or (C) the date the Administrative
     Committee modifies such Deferral Election pursuant to the terms of
     subsection (b)(4) hereof. If a Participant is transferred from the
     employment of a Participating Company to the employment of another
     Participating Company, his Deferral Election with the first Participating
     Company will remain in effect and will apply to his Compensation from the
     second Participating Company until the earlier of (A), (B) or (C) of the
     preceding sentence.

               (3)  Modification and Revocation. An Active Participant's
                    ---------------------------
     Deferral Election with a Participating Company shall terminate upon his
     ceasing to be an Employee of such Participating Company. Otherwise, an
     Active Participant's Deferral Election with respect to a Plan Year may not
     be modified or revoked by the Active Participant during that Plan Year. If
     an Active Participant does not make a new Deferral Election for any
     subsequent Plan Year, the most recent Deferral Election in place will
     remain in effect for that subsequent Plan Year.

               (4)  Compliance with SEC Rule 16b-3. Notwithstanding any other
                    ------------------------------
     provision of the Plan, the Administrative Committee shall take any and all
     actions as may be necessary with regard to Deferral Elections made by
     Participants who are deemed to be "insiders" of the Company under the terms
     of the Securities Exchange Act of 1934, as amended (the "1934 Act"), in
     order to meet the requirements of Rule 16b-3 and regulations promulgated
     thereunder.

Before-Tax Contributions up to the first 6 percent of the Participant's
Compensation (or the difference between the amount of Before-Tax Contributions
made by the Participant and matched by the Company under the Retirement Savings
Plus Plan so that only a total of 6 percent of the Participant's Compensation is
matched under both the RSP and the Plan).  Matching Contributions for a Plan
Year shall be reduced by the amount of any Forfeitures available for
reallocation during that Plan Year.

which the Trustee consents. Such other Investment Funds also may be established
and maintained for any limited purposes the Administrative Committee may direct.

<PAGE>

          (c)  Reinvestment of Cash Earnings.  Any investment earnings received
               -----------------------------
in the form of cash with respect to any Investment Fund (in excess of the
amounts necessary to make cash distributions for fractional shares of Company
Stock or to pay Plan or Trust expenses) shall be reinvested in such Investment
Fund.

    5.3   Investment Procedures.
          ---------------------

          Each Participant or Beneficiary generally may direct the manner in
which his Accounts shall be invested in and among the Investment Funds;
provided, however, that the Administrative Committee shall have sole discretion
as to investment of a Participant's or Beneficiary's Accounts and may refuse to
follow a Participant's or Beneficiary's investment directions. A Participant's
or Beneficiary's investment directions shall be made in accordance with the
following terms:

          (a)  Investment of Future Contributions. Except as otherwise provided
               ----------------------------------
in this Section [relating to special Investment Funds described in (S)5.2(b)],
each Participant may elect, on a form provided by the Administrative Committee,
the percentage of his future Before-Tax and Matching Contributions that will be
invested in each Investment Fund. An initial election of a Participant shall be
made as of the date the Participant commences or recommences participation in
the Plan and shall apply to all Before-Tax and Matching Contributions
attributable to payroll periods ending after such date. Such Participants may
make subsequent elections no more than once per week on a form provided by the
Administrative Committee, and such elections shall apply to all Before-Tax and
Matching Contributions attributable to payroll periods ending after such date.
Any election made pursuant to this subsection with respect to future Before-Tax
and Matching Contributions shall remain effective until changed by such
Participant.

          (b)  Investment of Existing Account Balances.  Except as otherwise
               ---------------------------------------
provided in this Section, each Participant or Beneficiary may elect, on a form
provided by the Administrative Committee, the percentage of his existing
Accounts that will be invested in each Investment Fund. Such Participant or
Beneficiary may make such elections no more than once per week on a form
provided by the Administrative Committee. Each such election shall apply to such
Participant's or Beneficiary's Account balance as of the date of such election,
and shall remain in effect until changed by such Participant or Beneficiary. In
the event a Participant fails to make an election for his existing Accounts
pursuant to the terms of this subsection (2) which is separate from his election
made for his future Before-Tax and Matching Contributions pursuant to the terms
of subsection (1) hereof, or if a Participant's investment election form is
incomplete or insufficient in some manner, the Participant's existing Accounts
will continue to be invested in the same manner provided under the terms of the
most recent election affecting that portion of his Accounts. The Administrative
Committee may determine at its discretion to charge a reasonable surcharge for
changes to investment of existing Account balances; payment of any such
surcharges may be made outside the Plan though payroll deduction or other
methods as may be determined by the Administrative Committee.

          (c)  Conditions Applicable to Elections. Allocations of investments in
               ----------------------------------
the various Investment Funds, as described in subsections (1) and (2) hereof,
shall be made in even multiples of 1 percent as directed by the Participant or
Beneficiary. The Administrative Committee shall have complete discretion to
adopt and revise procedures to be followed in making such investment elections.
Such procedures may include, but are not limited to, the format of the election
forms, the deadline for filing elections and the effective date of such
elections; provided, elections must be permitted at least once every 3 months.
Any procedures adopted by the Administrative Committee that are inconsistent
with the

                                       15
<PAGE>

deadlines specified in this Section shall supersede such provisions of this
Section without the necessity of a Plan amendment.

          (d)  Compliance with SEC Rule 16b-3.  Notwithstanding any other
               ------------------------------
provisions of the Plan, the Administrative Committee shall take any and all
actions as may be necessary with regard to investment directions made by
Participants who are deemed to be "insiders" of the Company under the terms of
the 1934 Act, in order to meet the requirements of Rule 16b-3 and regulations
promulgated thereunder.

     5.4  Acquisition of Company Stock.
          ----------------------------

          (a)  In General.  To the extent that Contributions and investment
               ----------
earnings on Company Stock are paid in cash, the Trustee, as directed by the
Administrative Committee, shall effect purchases of Company Stock in compliance
with all applicable securities laws, and in its sole discretion, may purchase
Company Stock in the open market and/or in privately negotiated transactions
with holders of Company Stock and/or the Controlling Company.  All purchases of
Company Stock by the Trust will be made at a price or prices which, in the
judgment of the Trustee, do not exceed the fair market value of such Company
Stock as of the date of the purchase.

          (b)  Stock Rights, Warrants or Options.  In the event any rights,
               ---------------------------------
warrants or options are issued on Company Stock, the Trustee may exercise them
for the acquisition of additional Company Stock, to the extent that cash is then
available and allocable to the Company Stock Fund. Any Company Stock acquired in
this fashion will be treated as Company Stock bought by the Trustee for the net
price paid. Any rights, warrants or options on Company Stock which cannot be
exercised for lack of available cash may be sold by the Trustee (provided the
sale thereof is reasonably practicable), and the proceeds of such a sale shall
be treated as a current cash dividend received on Company Stock.

    5.5   Value of Assets.
          ---------------

          For purposes under the Plan for which the value of assets must be
determined, the value of such assets shall be the fair market value.  For
purposes of purchasing or selling Company Stock through an exchange on any day,
the fair market value per share of such stock on such day shall be the price of
the stock on the New York Stock Exchange at the time of the purchase or sale.
For all other purposes under the Plan, the fair market value per share of the
Company Stock on any particular day shall be the closing price of such Company
Stock as reported on the New York Stock Exchange Composite Transaction listing
on the day preceding the particular day in question. If, for any reason, the
fair market value per share of Company Stock cannot be ascertained or is
unavailable for a particular day, the fair market value of such stock shall be
determined as of the nearest preceding day on which such fair market value can
be ascertained pursuant to the terms hereof.

                              VESTING IN ACCOUNTS
                              -------------------

     6.1  General Vesting Rule.
          --------------------

          All Participants shall at all times be fully vested in their Before-
Tax Account.  Except as provided in (S)6.2, the Matching Account of a
Participant shall vest in accordance with the following vesting schedule, based
on the total of the Participant's Years of Vesting Service:

          Years of Vesting Service             Vested Percentage of
          Completed by Participant        Participant's Matching Account
          ------------------------        ------------------------------

          Less than 3 Years               None
          3 Years, but less than 4         50%
          4 Years, but less than 5         75%
          5 Years or more                 100%

     6.2  Vesting Upon Other Occurrences.
          -------------------------------

          Notwithstanding (S)6.1, a Participant's Matching Account shall become
100 percent vested and nonforfeitable upon the occurrence of any of the
following events:

          (a)  The Participant's attainment of Normal Retirement Age while still
employed as an employee of any Affiliate;

          (b)  The Participant's death while still employed as an employee of
any Affiliate; or

          (c)  The Participant's becoming Disabled while still employed as an
employee of any Affiliate.

          Notwithstanding (S)6.1, effective as of September 30, 1998, the
Matching Account of those Participants who were employed by an Affiliate, but
who terminated employment with such Affiliate to go directly to work for
SouthStar Energy Services LLC on September 30, 1998, shall be 100 percent vested
and nonforfeitable as of such date.

     6.3  Timing of Forfeitures.
          ---------------------

          If a Participant who is not yet 100 percent vested in his Matching
Account separates from service with all Affiliates, the nonvested amount in his
Matching Account shall be immediately forfeited and shall become available as a
Forfeiture as of the Valuation Date coincident with or immediately following the
date on which such termination occurs; provided, if a Participant has no vested
interest in his Account at the time he separates from service, he shall be
deemed to have received a cash-out distribution at the time he separates from
service, and the forfeiture provisions of this Section shall apply. If such a
Participant resumes employment with an Affiliate, such forfeited amount shall
not be restored.

                                       17

                                  ARTICLE VII

                              PAYMENT OF BENEFITS
                              -------------------

     7.1  Benefit Payments Upon Termination of Service for any Reason Other Than
          ----------------------------------------------------------------------
Death.
- -----

          If a Participant separates from service with all Affiliates for any
reason other than death, he (or his Beneficiary, if he dies after such
separation from service) shall be entitled to receive a distribution of the
total of (i) the entire vested amount credited to his Account, determined as of
the Valuation Date coincident with or immediately preceding the date payment of
such distribution is to be made, plus (ii) the vested amount of any
Contributions made on his behalf since such Valuation Date. For purposes of this
subsection, the "date payment of such distribution is to be made" refers to the
date established for such purpose by administrative practice, even if actual
payment is made at a later date due to delays in the valuation, administrative
or any other procedure. Benefits payable to a Participant under this Section
shall be distributed within sixty days after the end of the Plan Year after such
Participant separates from service with all Affiliates for any reason other than
death.

     7.2  Death Benefits.
          --------------

          If a Participant dies before payment of his benefits from the Plan is
made, the Beneficiary or Beneficiaries designated by such Participant in his
latest beneficiary designation form filed with the Administrative Committee in
accordance with the terms of (S)7.4 shall be entitled to receive a distribution
of the total of (i) the entire vested amount credited to such Participant's
Account, determined as of the Valuation Date coincident with or immediately
preceding the date payment of such distribution is to be made, plus (ii) any
Contributions made on such Participant's behalf since such Valuation Date. For
purposes of this subsection, the "date payment of such distribution is to be
made" refers to the date established for such purpose by administrative
practice, even if actual payment is made at a later date due to delays in the
valuation, administrative or any other procedure. Benefits payable to a
Beneficiary or Beneficiaries under this Section shall be distributed sixty days
after the end of the Plan Year in which the Participant's death occurs.

     7.3  Form of Distribution.
          --------------------

          Any distribution to a Participant or his Beneficiary or Beneficiaries
shall be made in the form of a single sum cash payment. Such single sum cash
payment may be divided among multiple Beneficiaries, as applicable.

     7.4  Beneficiary Designation.
          -----------------------

          (a)  General.  Participants shall designate and from time to time may
               -------
redesignate their Beneficiary or Beneficiaries in such form and manner as the
Administrative Committee may determine.  If any Participant dies prior to
receiving his benefits under the Plan, his Account shall be changed to the name
of such deceased Participant's named or deemed Beneficiary or Beneficiaries.

          (b)  No Designation or Designee Dead or Missing.  In the event that:
               ------------------------------------------

               (1)  a Participant dies without designating a Beneficiary;

                                       18
<PAGE>

               (2)  the Beneficiary designated by a Participant is not surviving
     when a payment is to be made to such person under the Plan, and no
     contingent Beneficiary was designated by the Participant; or

               (3)  the Beneficiary designated by a Participant cannot be
     located by the Administrative Committee within 1 year from the date
     benefits are to commence to such person; then, in any of such events, the
     Beneficiary of such Participant with respect to any benefits that remain
     payable under the Plan shall be the Participant's Surviving Spouse, if any,
     and if not, then the estate of the Participant.

     7.5  Hardship Withdrawals.
          --------------------

          (a)  Parameters of Hardship Withdrawals.  A Participant may make a
               ----------------------------------
withdrawal on account of hardship from his vested Account.  For purposes of this
subsection, a withdrawal will be on account of "hardship" only if it is
necessary to respond to an "unforeseeable emergency" resulting in a severe
financial need of the Participant. A withdrawal based on financial hardship
cannot exceed the amount necessary to meet the severe financial need created by
the hardship and not reasonably available from other resources of the
Participant. The Administrative Committee shall make its determination, as to
whether a Participant has suffered a severe financial need as a result of an
unforeseeable emergency and whether it is necessary to use a hardship withdrawal
from the Plan to satisfy that need on the basis of all relevant facts and
circumstances.

          (b)  Unforeseeable Emergency.  For purposes of the Plan, an
               -----------------------
unforeseeable emergency shall be a sudden and unexpected illness or accident of
the Participant or of a dependent (as defined in Code Section 152(a)) of the
Participant, loss of the Participant's property due to casualty, or other
similar extraordinary and unforeseeable circumstances arising as a result of
events beyond the control of the Participant. The circumstances that will
constitute an unforeseeable emergency will depend upon the facts of each case,
but, in any case, payment may not be made to the extent that such hardship is or
may be relieved -

               (i)   through reimbursement or compensation by insurance or
          otherwise;

               (ii)  by liquidation of the Participant's assets, to the extent
          the liquidation of such assets would not itself cause severe financial
          hardship; or

               (iii) by cessation of deferrals under the Plan.

Examples of events not considered to be unforeseeable emergencies include the
need to send a participant's child to college or the desire to purchase a home.

          (c)  Application for Hardship Withdrawal.  All applications for
               -----------------------------------
hardship withdrawals shall be in writing on a form provided by the
Administrative Committee and shall contain such information as the
Administrative Committee may reasonably request.

          (d)  Payment of Withdrawal.  The amount of a hardship withdrawal shall
               ---------------------
be paid to a Participant in a single sum in cash as soon as practicable after
the Administrative Committee approves the withdrawal application.

                                       19
<PAGE>

     7.6  Unclaimed Benefits.
          ------------------

          In the event a Participant becomes entitled to benefits under the Plan
other than death benefits and the Administrative Committee is unable to locate
such Participant (after sending a letter, return receipt requested, to the
Participant's last known address, and after such further diligent efforts as the
Administrative Committee in its sole discretion deems appropriate) within 1 year
from the date upon which he becomes so entitled, the Administrative Committee
shall direct that such benefits be paid to the Beneficiary of such Participant;
provided, if the distribution is payable upon the termination of the Plan, the
Administrative Committee shall not be required to wait until the end of such 1-
year period. If the Participant and the Beneficiary cannot be located and fail
to claim such benefits by the end of the 5th Plan Year following the Plan Year
in which such Participant becomes entitled to such benefits, then the full
Account of the Participant shall be deemed abandoned and shall be used to reduce
the Matching Contributions of the Participating Company or Companies which
employed such Participant; provided, in the event such Participant or
Beneficiary is located or makes a claim subsequent to the allocation of the
abandoned Account but prior to the expiration of the time within which any such
person's claim to the Account would expire under appropriate state law, then the
amount of the abandoned Account (unadjusted for any investment gains or losses
from the time of abandonment) shall be restored (from abandoned Accounts, Trust
earnings or Contributions made by the Participating Company or Companies with
whom the Participant formerly was employed) and paid to such Participant or
Beneficiary, as appropriate; and, provided, further, the Administrative
Committee, in its sole discretion, may delay the deemed date of abandonment of
any such Account for a period longer than the prescribed 5 Plan Years if it
believes that it is in the best interest of the Plan to do so.

     7.7  Claims.
          ------

          (a)  Procedure.  Claims for benefits under the Plan may be filed with
               ---------
the Administrative Committee on forms supplied by the Administrative Committee.
The Administrative Committee shall furnish to the claimant written notice of the
disposition of a claim within 90 days after the application therefor is filed;
provided, if special circumstances require an extension of time for processing
the claim, the Administrative Committee shall furnish written notice of the
extension to the claimant prior to the termination of the initial 90-day period,
and such extension shall not exceed one additional, consecutive 90-day period.
In the event the claim is denied, the notice of the disposition of the claim
shall provide the specific reasons for the denial, cites of the pertinent
provisions of the Plan, and, where appropriate, an explanation as to how the
claimant can perfect the claim and/or submit the claim for review.

          (b)  Review Procedure.  Any Participant or Beneficiary who has been
               ----------------
denied a benefit, or his duly authorized representative, shall be entitled, upon
request to the Administrative Committee, to appeal the denial of his claim. To
do so, the claimant must make a written request to the Administrative Committee
for further consideration of his position. The claimant, or his duly authorized
representative, may review pertinent documents related to the Plan and in the
Administrative Committee's possession in order to prepare the appeal. The form
containing the request for review, together with a written statement of the
claimant's position, must be filed with the Administrative Committee no later
than 60 days after receipt of the written notification of denial of a claim
provided for in subsection (a). The Administrative Committee's decision shall be
made within 120 days following the filing of the request for review and shall be
communicated in writing to the claimant. If unfavorable, the notice of decision
shall explain the reason or reasons for denial and indicate the provisions of
the Plan or other documents used to arrive at the decision.

                                       20
<PAGE>

          (c)  Satisfaction of Claims.  Any payment to a Participant or
               ----------------------
Beneficiary or to their legal representative or heirs at law, all in accordance
with the provisions of the Plan, shall to the extent thereof be in full
satisfaction of all claims hereunder against the Trustee, the Administrative
Committee and the Controlling Company, any of whom may require such Participant,
Beneficiary, legal representative or heirs at law, as a condition to such
payment, to execute a receipt and release therefor in such form as shall be
determined by the Trustee, the Administrative Committee or the Controlling
Company, as the case may be. If receipt and release shall be required but
execution by such Participant, Beneficiary, legal representative or heirs at law
shall not be accomplished so that the terms of (S)(S) 7.1 and 7.2 may be
fulfilled, such benefits may be distributed or paid into any appropriate court
or to such other place as such court shall direct, for disposition in accordance
with the order of such court, and such distribution shall be deemed to comply
with the requirements of (S)(S)7.1 and 7.2.

                                 ARTICLE VIII

                 ALLOCATION OF AUTHORITY AND RESPONSIBILITIES
                 --------------------------------------------

     8.1  Administrative Committee
          ------------------------

          (a)  Appointment and Term of Office.  The Administrative Committee
               ------------------------------
shall consist of not less than one member who shall be appointed by and serve at
the pleasure of the Board. The Board shall have the right to remove any member
of the Administrative Committee at any time. A member may resign at any time by
written resignation to the Board. If a vacancy in the Administrative Committee
should occur, a successor may be appointed by the Board. A written certification

hereunder, the Trustee shall be conclusively entitled to rely upon such
certification until the Trustee is otherwise notified in writing.

          (b)  Organization.  The Administrative Committee may elect a Chairman
               ------------
and a Secretary from among its members. In addition to those powers set forth

for the effective performance of its duties and may delegate to such agents such
powers and duties, whether ministerial or discretionary, as the Administrative
Committee may deem expedient or appropriate. The compensation of such agents who
are not full-time Employees of a Participating Company shall be fixed by the
Administrative Committee within limits set by the Board and shall be paid by the
Controlling Company (to be divided equitably among the Participating Companies)
or from the Trust Fund as determined by the Administrative Committee. The
Administrative Committee shall act by majority vote. Its members shall serve as
such without compensation.

          (c)  Powers and Responsibility.  The Administrative Committee shall
               -------------------------
have complete control of the administration of the Plan hereunder, with all
powers necessary to enable it properly to carry out its duties as set forth in
the Plan and the Trust Agreement.  The Administrative Committee shall have the
sole authority in its discretion to (i) construe the Plan and to determine all
questions that shall arise thereunder; (ii) decide all questions relating to the
eligibility of Employees to participate in the benefits of the Plan; (iii)
determine the benefits of the Plan to which any Participant or Beneficiary may
be entitled; (iv) maintain and retain records relating to Participants and

all sources so that the Trustee may maintain separate accounts for Participants
and Beneficiaries and make required payments of benefits; (vii) arrange for any
required fiduciary bonding and (viii) prepare and file or publish with the
Secretary of Labor, the Secretary of the Treasury, their delegates and all other

                                       21
<PAGE>

appropriate government officials all reports and other information required
under law to be so filed or published.

          (d)  Administrative Committee Records.  Any notice, direction, order,
               --------------------------------
request, certification or instruction of the Administrative Committee to the
Trustee shall be in writing and shall be signed by a member of the
Administrative Committee. The Trustee and every other person shall be entitled
to rely conclusively upon any and all such notices, directions, orders,
requests, certifications and instructions received from the Administrative
Committee and reasonably believed to be properly executed, and shall act and be
fully protected in acting in accordance therewith. All acts and determinations
of the Administrative Committee shall be duly recorded by its Secretary or under
his supervision, and all such records, together with such other documents as may
be necessary for the administration of the Plan, shall be preserved in the
custody of such Secretary.

          (e)  Reporting and Disclosure.  The Administrative Committee shall
               ------------------------
keep all individual and group records relating to Participants and Beneficiaries
and all other records necessary for the proper operation of the Plan. Such
records shall be made available to the Participating Companies and to each
Participant and Beneficiary for examination during normal business hours except
that a Participant or Beneficiary shall examine only such records as pertain
exclusively to the examining Participant or Beneficiary and the Plan and Trust
Agreement. The Administrative Committee shall prepare and shall file as required
by law or regulation all reports, forms, documents and other items required by
any relevant statute, each as amended, and all regulations thereunder. This
provision shall not be construed as imposing upon the Administrative Committee
the responsibility or authority for the preparation, preservation, publication
or filing of any document required to be prepared, preserved or filed by the
Trustee or by any other entity to whom such responsibilities are delegated by
law or by the Plan.

          (f)  Plan Construction.  The Administrative Committee shall take such
               -----------------
steps as are considered necessary and appropriate to remedy any inequity that
results from incorrect information received or communicated in good faith or as
the consequence of an administrative error. The Administrative Committee shall
interpret the Plan and shall determine the questions arising in the
administration, interpretation and application of the Plan. The Administrative
Committee shall endeavor to act, whether by general rules or by particular
decisions, so as not to discriminate in favor of or against any person and so as
to treat all persons in similar circumstances uniformly. The Administrative
Committee shall correct any defect, reconcile any inconsistency or supply any
omission with respect to the Plan.

          (g)  Assistants and Advisers.  The Administrative Committee shall
               -----------------------
have the right to hire, at the expense of the Controlling Company (to be divided
equitably among the Participating Companies), such professional assistants and
consultants as it, in its sole discretion, deems necessary or advisable. To the
extent that the costs for such assistants and advisers are not so paid by the
Controlling Company, they shall be paid at the direction of the Administrative
Committee from the Trust Fund as an expense of the Trust Fund. The
Administrative Committee and the Participating Companies shall be entitled to
rely upon all certificates and reports made by an actuary, accountant or
attorney selected pursuant to this (S)8.1; the Administrative Committee, the
Participating Companies, and the Trustee shall be fully protected in respect to
any action taken or suffered by them in good faith in reliance upon the advice
or opinion of any such actuary, accountant or attorney; and any action so taken
or suffered shall be conclusive upon each of them and upon all other persons
interested in the Plan.

          (h)  Indemnification.  The Administrative Committee and each member of
               ---------------
that Committee shall be indemnified by the Participating Companies against
judgment amounts, settlement amounts (other than amounts paid in settlement to
which the Participating Companies do not consent) and expenses reasonably
incurred by the Committee or each member of the Committee in connection with any
action to which the Committee or any member thereof may be a party (by reason of
his service

                                       22
<PAGE>

as a member of the Committee) except in relation to matters as to which the
Committee or any member thereof shall be adjudged in such action to be
personally guilty of gross negligence or willful misconduct in the performance
of its or any member's duties. The foregoing right to indemnification shall be
in addition to such other rights as such Committee or each Committee member may
enjoy as a matter of law or by reason of insurance coverage of any kind. Rights
granted hereunder shall be in addition to and not in lieu of any rights to
indemnification to which such Committee or each Committee member may be entitled
pursuant to the by-laws of the Controlling Company. Service on the
Administrative Committee shall be deemed in partial fulfillment of a Committee
member's function, if any, as an Employee, officer and/or director of the
Controlling Company or any Participating Company.

     8.2  Controlling Company and Board.
          -----------------------------

          (a)  General Responsibilities.  The Controlling Company and the Board
               ------------------------
shall have the authority and responsibility to (i) appoint the Trustee and the
Administrative Committee and to monitor each of their performances; (ii)
communicate such information to the Trustee and the Administrative Committee as
each needs for the proper performance of its duties; (iii) provide channels and
mechanisms through which the Administrative Committee and/or the Trustee can
communicate with Participants and Beneficiaries; and (iv) perform such duties as
are imposed by law or by regulation and serve as Plan Administrator in the
absence of an appointed Administrative Committee.

          (b)  Allocation of Authority.  In the event any of the areas of
               -----------------------
authority and responsibilities of the Controlling Company and the Board overlap
with that of any other entity, the Controlling Company and the Board shall
coordinate with such other entity the execution of such authority and
responsibilities; provided, the decision of the Controlling Company and the
Board with respect to such authority and responsibilities ultimately shall be
controlling.

          (c)  Authority of Participating Companies.  Notwithstanding anything
               ------------------------------------
herein to the contrary, and in addition to the authority and responsibilities
specifically given to the Participating Companies in the Plan, the Controlling
Company, in its sole discretion, may grant the Participating Companies such
authority and charge them with such responsibilities as the Controlling Company
deems appropriate.

     8.3  Trustee.
          -------

          The Trustee shall have the powers and duties set forth in the Trust
Agreement.

     8.4  Delegation.
          ----------

          Entities described in this section shall have the power to delegate
specific responsibilities (other than Trustee responsibilities) to persons whom
shall serve at the pleasure of the entity making such delegation and, if full-
time Employees of a Participating Company, without compensation. Any such person
may resign by delivering a written resignation to the delegating entity.
Vacancies created by any reason may be filled by the appropriate entity or the
assigned responsibilities may be reabsorbed or redelegated by the entity.

                      AMENDMENT, TERMINATION AND ADOPTION
                      -----------------------------------

     9.1  Amendment.
          ---------

          The provisions of the Plan may be amended at any time and from time to
time by the Board; provided:

          (a)  No amendment shall increase the duties or liabilities of the
Trustee without the consent of such party;

          (b)  No amendment shall decrease the balance or vested percentage of
an Account;

          (c)  Each amendment shall be approved by the Board by resolution; and

          (d)  No amendment shall be made to Section 5.1(c) of the Plan (unless
required by law).

     9.2  Termination.
          -----------

          (a)  Right to Terminate.  The Controlling Company expects the Plan to
               ------------------
be continued indefinitely, but it reserves the right to terminate the Plan or to
completely discontinue Contributions to the Plan at any time by action of the
Board. In either event, the Administrative Committee, each Participating Company
and the Trustee shall be promptly advised of such decision in writing.

          (b)  Dissolution of Trust.  In the event that the Administrative
               --------------------
Committee decides to dissolve the Trust, as soon as practicable following the
termination of the Plan or the Administrative Committee
's decision, whichever is
later, the assets under the Plan shall be converted to cash or other
distributable assets, to the extent necessary to effect a complete distribution
of the Trust assets to the Controlling Company.

     9.3  Adoption of the Plan by a Participating Company.
          -----------------------------------------------

          (a)  Procedures for Participation.  In order for a company to become a
               ----------------------------
Participating Company, the Administrative Committee must designate such company
as a Participating Company and specify the effective date of such designation.
The name of any company which shall commence participation in the Plan, along
with the effective date of its participation, shall be recorded on Schedule A
hereto which shall be appropriately modified each time a Participating Company
is added or deleted. To adopt the Plan as a Participating Company, the board of
directors of the company must approve a resolution expressly adopting the Plan
for the benefit of its eligible employees and accepting designation as a
Participating Company, subject to all of the provisions of this Plan and of the
Trust. The resolution shall specify the date as of which the designation as a
Participating Company shall be effective. A copy of the resolution (certified if
requested) of the board of directors of the adopting Participating Company shall
be provided to the Administrative Committee. Upon adoption of the Plan by a
Participating Company as herein provided, the Employees of such company shall be
eligible to participate in the Plan subject to the terms hereof and of the
resolution of the Administrative Committee designating the adopting company as
such.

          (b)  Authority under Plan.  As long as a Participating Company's
               --------------------
designation as such remains in effect, such Participating Company shall be bound
by, and subject to, all provisions of the Plan and the Trust. The exclusive
authority to amend the Plan and the Trust shall be vested in the

                                       24
<PAGE>

Administrative Committee, and no Participating Company other than the
Controlling Company shall have any right to amend the Plan or the Trust. Any
amendment to the Plan or the Trust adopted by the Administrative Committee shall
be binding upon every Participating Company without further action by such
Participating Company.

           (c)  Contributions to Plan.  As long as each Participating Company
                ---------------------
shall be so designated, such Participating Company shall be required to make
Contributions to the Plan at such times and in such amounts as specified in
Article III. The Contributions made (or to be made) to the Plan by the
Participating Companies shall be allocated between and among such companies in
whatever equitable manner or amounts as the Administrative Committee shall
determine.

           (d)  Withdrawal from Plan.  No Participating Company other than the
                --------------------
Controlling Company shall have the right to terminate the Plan. However, any
Participating Company may withdraw from the Plan, with the approval of the
Administrative Committee, by action of its board of directors, provided such
action is communicated in writing to the Administrative Committee. The
withdrawal of a Participating Company shall be effective as of the last day of
the Plan Year which follows receipt of the notice of withdrawal (unless the
Controlling Company consents to a different effective date). In addition, the
Administrative Committee may terminate the designation of a Participating
Company to be effective on such date as the Administrative Committee specifies.
Any such Participating Company which ceases to be a Participating Company shall
be liable for all costs accrued through the effective date of its withdrawal or
termination. In the event of the withdrawal or termination of a Participating
Company as provided in this Section, such Participating Company shall have no
right to direct that assets of the Plan be transferred to a successor plan for
its employees, unless such transfer is approved by the Controlling Company or
Administrative Committee in its sole discretion.

                                 MISCELLANEOUS
                                 -------------

     10.1  Nonalienation of Benefits and Spendthrift Clause.
           ------------------------------------------------

           None of the Accounts, benefits, payments, proceeds or distributions
under the Plan shall be subject to the claim of any creditor of a Participant or
Beneficiary or to any legal process by any creditor of such Participant or of
such Beneficiary; and neither such Participant nor any such Beneficiary shall
have any right to alienate, commute, anticipate or assign any of the Accounts,
benefits, payments, proceeds or distributions under the Plan except to the
extent expressly provided herein. If any Participant shall attempt to dispose of
his Account or the benefits provided for him hereunder or to dispose of the
right to receive such benefits, or, in the event there should be an effort to
seize such Account or benefits by attachment, execution or other legal or
equitable process, such right may pass and be transferred, at the discretion of
the Administrative Committee, to such person or persons as may be selected by
the Administrative Committee from among the Beneficiaries, if any, theretofore
designated by the Participant, or from the Spouse, children or other dependents
of the Participant, in such shares as the Administrative Committee may appoint.
Any appointments so made by the Administrative Committee may be revoked by it at
any time, and further appointments made by it may include the Participant.

     10.2  Headings.
           --------

           The headings and subheadings in the Plan have been inserted for
convenience of reference only and are to be ignored in any construction of the
provisions hereof.

<PAGE>

     10.3  Construction, Controlling Law.
           -----------------------------

           In the construction of the Plan, the masculine shall include the
feminine and the feminine the masculine, and the singular shall include the
plural and the plural the singular, in all cases where such meanings would be
appropriate. Unless otherwise specified, any reference to a section shall be
interpreted as a reference to a section of the Plan. The Plan shall be construed
in accordance with the laws of the State of Georgia and applicable federal laws.

     10.4  No Contract of Employment.
           -------------------------

           Neither the establishment of the Plan, nor any modification thereof,
nor the creation of any fund, trust or account, nor the payment of any benefits
shall be construed as giving any Participant, Employee or any person whomsoever
the right to be retained in the service of any Affiliate, and all Participants
and other Employees shall remain subject to discharge to the same extent as if
the Plan had never been adopted.

     10.5  Legally Incompetent.
           -------------------

           The Administrative Committee may in its discretion direct that
payment be made and the Trustee shall make payment on such direction, directly
to an incompetent or disabled person, whether incompetent or disabled because of
minority or mental or physical disability, or to the guardian of such person or
to the person having legal custody of such person, without further liability
with respect to or in the amount of such payment either on the part of any
Participating Company, the Administrative Committee or the Trustee.

     10.6  Heirs, Assigns and Personal Representatives.
           -------------------------------------------

           The Plan shall be binding upon the heirs, executors, administrators,
successors and assigns of the parties, including each Participant and
Beneficiary, present and future.

     10.7  Unsecured Creditor Rights.
           -------------------------

           No Participant or Beneficiary shall have any right to, or interest
in, any assets of the Trust Fund other than that of a general unsecured creditor
of the Controlling Company.

     10.8  Legal Action.
           ------------

           In any action or proceeding involving the assets held with respect to
the Plan or Trust Fund or the administration thereof, the Participating
Companies, the Administrative Committee and the Trustee shall be the only
necessary parties and no Participants, Employees, or former Employees of the
Company, their Beneficiaries or any other person having or claiming to have an
interest in the Plan shall be entitled to any notice of process; provided, that
such notice as is required by the IRS and the Department of Labor to be given in
connection with Plan amendments, termination, curtailment or other activity
shall be given in the manner and form and at the time so required. Any final
judgment which is not appealed or appealable that may be entered in any such
action or proceeding shall be binding and conclusive on the parties hereto, the
Administrative Committee and all persons having or claiming to have an interest
in the Plan.

     10.9  Severability.
           ------------

           If any provisions of the Plan shall be held invalid or unenforceable,
such invalidity or unenforceability shall not affect any other provisions
hereof, and the Plan shall be construed and enforced as if such provisions had
not been included.

                                       26

     10.10  Predecessor Service.
            -------------------

            In the event a Participating Company maintains the Plan as successor
to a predecessor employer who maintained the Plan, service for the predecessor
employer shall be treated as service for the Participating Company.

     10.11  Plan Expenses.
            -------------

            Expenses incurred with respect to administering the Plan and Trust
shall be paid by the Trustee from the Trust Fund only to the extent such costs
are not paid by the Participating Companies or to the extent the Controlling
Company requests that the Trustee reimburse it for its payment of such expenses.

            IN WITNESS WHEREOF, the Controlling Company has caused this Plan to
be executed by its duly authorized officers and its corporate seal to be affixed
hereto, all as of the date first above written.

Attention:  Mr. David Guinn

Re:  Precedent Agreement Dated April 16, 1998,
     As Amended By Letter Agreements Dated
     October 13, 1998, December 14, 1998,
     February 15, 1999, and August 11, 1999
     (collectively, the "Agreement"), By
     and Between Etowah LNG Company, L.L.C. ("Etowah")
     and Atlanta Gas Light Company ("AGLC")

Dear David:

The August 11, 1999 Letter Agreement referenced above provides that AGLC has
until October 15, 1999, in which to exercise its rights to terminate the
Agreement pursuant to the so-called "PSC-Out" contained in Paragraph 3 of the
Agreement.  In lieu of exercising its termination rights under Paragraph 3 of
the Agreement at this time, AGLC would like an extension of time in which to
assess the extent and timing of its storage needs and to determine the role of
the Etowah service in AGLC's gas capacity plan.  Accordingly, in consideration
of AGLC foregoing its present right to exercise the PSC-Out and in consideration
of the mutual agreements set forth in this letter, AGLC and Etowah agree as
follows:

          1.  Paragraph 3 of the Agreement is hereby amended and restated in its
              entirety as follows:

              3.   If Company accepts its FERC Authorization, then within 30
                   days Company and Customer shall execute and deliver an LNG-1
                   Service Agreement that provides for (i) a Maximum Daily
                   Vaporization Quantity (MDVQ) of 200,000 Mcf per day, (ii) a
                   Primary Delivery Point (subject to change by mutual agreement
                   and according to Company's FERC-approved tariff)

               at the interconnect between Company's Facility and Customer's
               Facility, and (iii) a primary term of 20 years from the in-
               service date, subject to Paragraph 8(a); provided, however, that
               Company's obligation to provide service pursuant to the executed
               Service Agreement remains subject to Company's receipt and
               acceptance of any remaining necessary contractual and property
               rights, financing arrangements, and regulatory approvals, in form
               and substance satisfactory to Company.  Any other provision of
               this Paragraph 3 to the contrary notwithstanding, Customer and
               Company agree that the obligations, agreements, and
               representations in this Precedent Agreement remain subject of the
               following (PSC-Out):  if Customer (i) files a bona fide Gas
               supply Plan, which includes, among other things, the service for
               which Customer has subscribed from Company (Storage Service) with
               the Georgia Public Service Commission (PSC) on or before August
               1, 1998;  (ii) pursues, on a best efforts basis, approval of the
               Gas Supply Plan; and (iii) either (a) receives from the PSC by
               September 30, 2000, an order(s) rejecting, disapproving, or
               excluding those portions of the Gas Supply Plan that specifically
               relate to the Storage Service, or (b) receives from the PSC by
               September 30, 2000, an order that places Customer at unreasonable

                           INDEMNIFICATION AGREEMENT


     This Indemnification Agreement is made and entered into on this 15/th/ day
of January 1999 by Piedmont Propane Company ("Indemnifying Party") in favor of
AGL Resources Inc. ("AGLR"). AGLR's affiliate, Atlanta Gas Light Services, Inc.,
and the Indemnifying Party's affiliate, Piedmont Energy Company (the
"Affiliate"), are parties to that certain Limited Liability Company Agreement of
SouthStar Energy Services LLC dated July 1, 1998 ("LLC Agreement") as members of
SouthStar Energy Services LLC ("SouthStar").  Pursuant to that certain Guaranty
Agreement (the "Guaranty"), effective November 1, 1998, between AGLR and Atlanta
Gas Light Company, AGLR has agreed to guaranty SouthStar's obligations to
Atlanta Gas Light Company.  AGLR's agreement with SouthStar to provide the
Guaranty to Atlanta Gas Light Company was subject to the condition that certain
affiliates of each member of SouthStar would indemnify AGLR against any losses
AGLR incurs as a result of AGLR providing financial support for SouthStar under
the Guaranty in accordance with the applicable SouthStar member's Allocable
Share of Net Profits and Losses, as set forth in the LLC Agreement.  This
Indemnification Agreement sets forth the terms and conditions of that
indemnification.

     In consideration of the benefit the Indemnifying Party and its affiliates
derive from AGLR providing financial support to SouthStar pursuant to the
Guaranty and the benefit to AGLR of the Indemnifying Party indemnifying AGLR,
the parties agree as follows:

1.  The Indemnifying Party shall indemnify, defend and hold AGLR harmless
    against any losses, costs, fees, liabilities or other expenses AGLR incurs
    as a result of AGLR's providing financial support for SouthStar under the
    Guaranty ("Indemnified Expenses"). The Indemnifying Party shall be liable
    for indemnifying AGLR hereunder for an amount equal to the product of the
    Affiliate's Allocable Share (as set forth in the LLC Agreement or any
    successor agreement) and the Indemnified Expenses. Notwithstanding any
    statement herein to the contrary, the Indemnifying Party shall not be liable
    to AGLR to the extent that the Indemnified Expenses resulted from AGLR's
    gross negligence or willful misconduct.

2.  AGLR shall invoice the Indemnifying Party (at the address set forth in
    numbered paragraph 9 below) no later than ten days prior to the end of each
    calendar month for the Indemnifying Party's share of the Indemnified
    Expenses due from the previous calendar month or any portion thereof. The
    Indemnifying Party shall pay AGLR the amount of such invoice (via wire
    transfer to the account specified on the invoice) no later than the last day
    of the calendar month during which AGLR sent the Indemnifying Party an
    invoice.
<PAGE>

    If the Indemnifying Party fails to pay all of the amount of any invoice when
    that amount becomes due, the Indemnifying Party shall pay AGLR a late charge
    on the unpaid balance that shall accrue daily on each calendar day from the
    due date at an annual rate equal to two percentage points above the then-
    effective monthly prime commercial lending rate per annum announced by
    NationsBank, N.A. from time to time multiplied by the unpaid balance;
    provided, that for any period that such rate exceeds any applicable maximum
    rate permitted by law, the rate shall equal the applicable maximum rate.

3.  This Indemnification Agreement shall inure to the benefit of each party, its
    successors, assigns and creditors, and can be modified only by a written
    instrument signed by the Indemnifying Party and AGLR. No Indemnifying Party
    shall have the right to assign this Indemnification Agreement or its
    obligations hereunder to any person or entity without the prior written
    consent of AGLR, which shall not be unreasonably withheld.

4.  This Indemnification Agreement shall be governed by, and construed in
    accordance with the internal laws (but not the laws concerning conflicts of
    laws) of the state of Georgia.

5.  The Indemnifying Party represents and warrants to AGLR that it is authorized
    to indemnify AGLR under the terms of this Indemnification Agreement, that it
    has all of the rights and powers necessary to do so, and that the individual
    signing below is authorized to bind the Indemnifying Party to its
    obligations under this Indemnification Agreement.

6.  The Indemnifying Party hereby agrees to provide AGLR with copies of
    Indemnifying Party's annual financial statements (consisting of at least a
    balance sheet and statements of income and cash flows) within 90 days
    following the end of the fiscal year to which such financial statements
    relate. If such financial statements have been reviewed or audited, the
    statements provided pursuant to the immediately preceding sentence shall be
    the reviewed or audited statements, as the case may be.

7.  The Indemnifying Party hereby agrees to notify AGLR within 45 days following
    the close of each of the first three quarters of each of Indemnifying
    Party's fiscal years if at the end of such quarter, Indemnifying Party's
    stockholders' equity, determined in accordance with generally accepted
    accounting principles consistently applied, shall be less than $30 million.

8.  On the date of each delivery of financial statements pursuant numbered
    paragraph 6 above, Indemnifying Party represents and warrants to AGLR that
    the balance sheet delivered by Indemnifying Party on such date reflects all
    obligations, contingent or otherwise, which in accordance with generally
    accepted accounting principles should be classified upon Indemnifying
    Party's balance sheet as liabilities or disclosed in footnotes thereto.

    proposed funding thereof the aggregate principal amount of all Loans then
    outstanding from GNG to SouthStar exceeds, or upon the funding of such
    proposed Loan would exceed, Thirty-Seven Million Five Hundred Thousand and
    no/100 Dollars (US$37,500,000.00), (ii) Piedmont, shall have no obligation
    to SouthStar
<PAGE>

    whatsoever to make any Loan pursuant to this Agreement if at the time of the
    proposed funding thereof the aggregate principal amount of all Loans then
    outstanding exceeds, or upon the funding of such proposed Loan would exceed,
    Twenty-Two Million Five Hundred Thousand and no/100 Dollars
    (US$22,500,000.00), and (iii) Dynegy, shall have no obligation to SouthStar
    whatsoever to make any Loan pursuant to this Agreement if at the time of the
    proposed funding thereof the aggregate principal amount of all Loans then
    outstanding exceeds, or upon the funding of such proposed Loan would exceed,
    Fifteen Million and no/100 Dollars (US$15,000,000.00). In the event that any
    one of the parties, GNG, Piedmont or Dynegy, shall fail to fund all or part
    of their respective portions of a SouthStar requested Loan pursuant to a
    Loan request made by SouthStar under this Agreement, neither of the other
    parties shall have any obligation to make a loan pursuant to that SouthStar
    request.

    Any person listed in Appendix A is authorized to consummate Loans from GNG,
    Piedmont and Dynegy under this Agreement on behalf of SouthStar.  Each of
    GNG, Piedmont and Dynegy shall designate in writing one contact person for
    all matters concerning Loans to SouthStar which designee may be changed by
    GNG, Piedmont or Dynegy, respectively, upon written notice to all parties
    to this Agreement.

2.  The Loans shall be made by GNG, Piedmont and Dynegy under this Agreement
    from time to time upon telephonic request from any person listed in Appendix
    A. At the time of each Loan, SouthStar will confirm the details of such Loan
    by transmitting a written notice to GNG, Piedmont and Dynegy, substantially
    in the form of Appendix B, detailing
<PAGE>

    the borrowing including: (i) the date of the notice; (ii) the requested date
    of the Loan; (iii) the aggregate principal amount of the Loan requested;
    (iv) the bank account to which Loan funds are to be disbursed; and (v) that
    the Loan is being requested pursuant to this Agreement. Further, such notice
    shall contain an affirmative representation and warranty that each of GNG,
    Piedmont and Dynegy are participating in the Loan pro rata based upon the
    following percentages: 50% for GNG; 30% for Piedmont; and 20% for Dynegy.

3.  Any and all payments (whether consisting of principal or interest) on an
    outstanding Loan shall be made by SouthStar to GNG, Piedmont and Dynegy pro
    rata based on the percentage of the Loan amount lent by each. In other
    words, assuming all Loans outstanding at the time of the payment were made
    by the Parties in percentages required in Paragraph 2 above, GNG, Piedmont
    and Dynegy shall each receive the following percentage of any principal
    payment or interest payment by SouthStar: 50% for GNG; 30% for Piedmont; and
    20% for Dynegy. All payments by SouthStar to GNG, Piedmont and Dynegy shall
    be applied first to accrued interest, then to principal. All payments shall
    be applied to Loans in the order in which each Loan was made, such that
    payments are applied first to repayment of interest and principal on the
    Loan that has been outstanding for the longest period of time. The principal
    balance of Loans outstanding to GNG, Piedmont and Dynegy may be prepaid, in
    whole or in part, at any time without penalty (provided that prepayments are
    applied in the order described in the immediately preceding sentence).
    Principal amounts repaid to GNG, Piedmont and Dynegy may be re-borrowed by
    SouthStar, provided that the aggregate outstanding principal balance of all
    Loans does not at any time exceed Seventy-Five Million and no/100 Dollars
<PAGE>

    (US$75,000,000.00) and provided further that all other terms and conditions
    of this Agreement are complied with.

4.  Interest will accrue on the outstanding principal balance of each Loan made
    by GNG, Piedmont, and Dynegy at an annual fixed rate equal to LIBOR
    (hereinafter defined), plus eighty-five basis points. Interest shall be
    calculated based upon the actual number of days the principal amount in
    question has been outstanding and based upon a year consisting of 360 days.

    Payments of interest on the outstanding principal balance of Loans shall be
    due and payable, in arrears, quarterly on September 30, 1999, December 31,
    1999, March 31, 2000, and June 27, 2000.  If the due date for an interest
    payment is not a business day, then such payment shall be due on the next
    succeeding business day.

    Notwithstanding anything herein to the contrary, any Loan payments (whether
    principal or interest) not made as and when due shall bear interest from the
    date due until paid at a floating rate equal to the Prime Rate (hereinafter
    defined) plus 200 basis points. Such interest shall be calculated on the
    basis of a 360 day year for the actual number of days elapsed.

    For purposes of this Agreement, LIBOR shall mean the London Interbank
    Offered Rate for the Applicable Period (hereinafter defined) as published in
    the "Money Rates" column of the Eastern Edition of the Wall Street Journal
    on the effective date of the Loan
<PAGE>

    in question, or if the Wall Street Journal is not published on such date,
    then as published in the Wall Street Journal on the next preceding business
    day.

    For purposes of this Agreement, "Applicable Period" shall mean: (i) one year
    for Loans with an effective date on or after June 30, 1999, but before
    December 28, 1999; (ii) six months for Loans with an effective date on or
    after December 28, 1999, but before March 28, 2000; (iii) three months for
    Loans with an effective date on or after March 28, 2000, but before May 28,
    2000; and (iv) one month for Loans with an effective date on or after May
    28, 2000.

    For purposes of the Agreement, "Prime Rate" shall mean the "Prime Rate" as
    published in the "Money Rates" column of the Eastern Edition of the Wall
    Street Journal on the date in question, or if the Wall Street Journal is not
    published on such date, then as published in the Wall Street Journal on the
    next preceding business day. Changes in the Prime Rate shall become
    effective on the date on which they are published in the Wall Street
    Journal.

5.  The amount borrowed by SouthStar under each Loan shall be deposited in an
    account specified by SouthStar in the confirmation notice specified in
    Section 2 hereof. Notwithstanding anything to the contrary contained in this
    Agreement or in any confirmation notice from SouthStar to GNG, Piedmont or
    Dynegy, all Loans (principal and interest) from GNG, Piedmont and Dynegy to
    SouthStar shall mature and shall be due and payable in full on June 27,
    2000. Simultaneously with its execution of this
<PAGE>

    Agreement, SouthStar shall execute Master Notes in favor of GNG, Piedmont
    and Dynegy in the forms set forth in Exhibit A, Exhibit B and Exhibit C,
    respectively.

6.  From the date of this Agreement until the later of (i) June 27, 2000, or
    (ii) the date on which all outstanding Loans have been paid in full, the
    Company covenants and agrees that it will not, without the prior written
    consent of each Lender, (a) pledge, sell, assign, or discount any of its
    accounts receivable, other than the discount of such accounts in the
    ordinary course of business for collection, or (b) pledge, sell or assign
    any gas storage inventory.

7.  This Agreement shall be governed by and construed under the laws of the
    State of Georgia.

IN WITNESS WHEREOF, the parties have caused this Agreement to be duly executed
by their duly authorized officers or other duly authorized representatives as of
the day and year first written above.

Nature of Our Business

Organizational Structure

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

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 which 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 operations
expenses include costs allocated from AGL Resources Inc.

AGL Resources currently owns or has an interest in the following non-utility
businesses:

 .  SouthStar Energy Services LLC ("SouthStar"), a joint venture among a
   subsidiary of AGL Resources Inc. and subsidiaries of Dynegy, Inc. and
   Piedmont Natural Gas Company. SouthStar markets natural gas and related
   services to residential and small commercial customers in Georgia and to
   industrial customers in the Southeast. SouthStar began marketing natural gas
   to customers in Georgia during the first quarter of fiscal 1999 under the
   trade name "Georgia Natural Gas Services;"

 .  AGL Investments, Inc., which currently manages certain non-utility businesses
   including:

     .  AGL Propane, Inc. ("Propane"), which engages in the sale of propane and
        related products and services in Georgia, Alabama, Tennessee and North
        Carolina;

     .  Trustees Investments, Inc., which owns Trustees Gardens, a residential
        and retail development located in Savannah, Georgia; and

     .  Utilipro, Inc. ("Utilipro"), in which AGL Resources has an 85% ownership
        interest and which engages in the sale of integrated customer care
        solutions and billing services to energy marketers in the United States
        and Canada;

     .  AGL Peaking Services, Inc., which owns a 50% interest in Etowah LNG
        Company LLC ("Etowah"), a joint venture with Southern Natural Gas
        Company. Etowah was formed for the purpose of constructing, owning, and
        operating a liquefied natural gas peaking facility.

Management's Discussion and Analysis of Results of Operations and Financial
Condition


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 were
purchasing natural gas from marketers who were approved and certificated by the
GPSC ("certificated marketers").

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 the same pattern as they
have historically.

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.

Since July 1, 1998, AGLC's charges for delivery service to end-use customers
have been based on a straight fixed variable ("SFV") rate design. Under SFV
rates, delivery service costs are recovered throughout the year consistent with
the way those costs are incurred. Prior to the implementation of SFV rates, AGLC
recovered the majority of its delivery service costs volumetrically based on the
amount of natural gas consumed by end-use customers. As a result, AGLC
historically recovered a disproportionately large share of its delivery costs in
the winter months and a disproportionately small share of its delivery costs in
the summer months. 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 with annual delivery service
revenues of prior years.

Certificated marketers, including AGL Resources' marketing affiliate, 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.

On May 3, 1999, pursuant to the Deregulation Act, the GPSC issued an order
establishing a final 100 day period for customers who had not yet chosen a
certificated marketer to make a choice. Customers who did not choose a
certificated marketer were randomly assigned to a certificated marketer under
the rules issued by the GPSC.

Certificated marketers were randomly assigned customers in proportion to their
respective market share as of August 11, 1999, and began serving those customers
on October 1, 1999. As a result, AGLC has exited the natural gas sales business
and, except for isolated circumstances, is responsible only for delivery service
for residential and small commercial customers.

During the transition to competition, AGLC continued to provide gas sales
service to customers who had not yet switched to a certificated marketer.  On
January 26, 1999, AGLC entered into a joint stipulation agreement with the GPSC
to resolve certain gas sales service issues. Among other requirements in the
joint stipulation agreement, AGLC implemented a rate structure for gas sales,
beginning with February 1999 bills, that more closely reflected customers'
actual gas usage and included a demand charge for fixed costs associated with
gas sales. This rate structure for gas sales service 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.

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 include
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,

                                                                              19

Management's Discussion and Analysis of Results of Operations and Financial

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.

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.

Operating Revenues

Operating revenues for fiscal 1999 decreased to $1,068.6 million from $1,338.6
million for fiscal 1998, a decrease of 20.2%.

Utility. Utility operating revenues decreased to $1,039.2 million for fiscal
1999 from $1,274.8 million for fiscal 1998. The decrease of $235.6 million was
primarily due to the following factors:

 .  Beginning November 1, 1998, customers began to switch from AGLC to
   certificated marketers for natural gas purchases as a result of the
   deregulation of natural gas commodity sales in Georgia. As of September 30,
   1999, approximately 1.2 million customers (approximately 82% of AGLC's total
   customers) had switched to a certificated marketer and, as a result, AGLC
   sold less gas. The remaining customers are expected to switch during the
   first quarter of fiscal 2000. The reduction in gas sold resulted in a
   decrease of $210.9 million in the utility's sales service revenues and a
   comparable decrease in the utility's gas costs. (See Utility section under
   Cost of Sales for a breakdown of the key components of this amount.);

 .  A decrease of $38.6 million in delivery service revenue due to the loss of
   ancillary service revenues and certain transition revenues. Transition
   revenues decreased $15.8 million due to customer migration to certificated
   marketers. The remaining decrease of $22.8 million was primarily due to the
   timing of the implementation of the new SFV rate structure for AGLC delivery
   service that became effective during the fourth quarter of fiscal 1998. (See
   Overview of the Transition from a Regulated to a Competitive Business
   Environment section under Nature of Our Business.); and

 .  A decrease of $6.4 million in revenue associated with AGLC's Integrated
   Resource Plan ("IRP"), which was phased out during fiscal 1998. Previously,
   AGLC passed through to its customers, which was reflected in revenue on a
   dollar-for-dollar basis, IRP expenses incurred, which also were included in
   operating expenses. Therefore, the phase-out of IRP had no effect on net
   income.

These decreases were partially offset by:

 .  An increase in AGLC's late payment fee revenue from end-use customers of
   $13.5 million. The increase was primarily due to the late payment fee
   structure that became effective July 1, 1998 as part of the transition to
   competition. The late payment fee revenue is not expected to continue at the
   same level during fiscal 2000 since AGLC will no longer bill end-use
   customers.

 .  AGLC recovered carrying costs related to storage gas inventories of $6.6
   million in fiscal 1999 from its customers within the parameters of the
   January 26, 1999 joint stipulation agreement with the GPSC and recorded these
   recovered carrying costs in operating revenue. During fiscal 1998, the
   recovered carrying costs from AGLC's customers of $5.4 million were recorded
   as other income. (See Note 2. Impact of Deregulation.)

Management's Discussion and Analysis of Results of Operations and Financial
Condition

Non-utility. Non-utility operating revenues decreased to $29.4 million for
fiscal 1999 from $63.8 million for fiscal 1998. The decrease of $34.4 million
was primarily due to the following factors:

 .  A decrease in revenues of $38.0 million primarily attributable to a change
   from consolidation of a wholly-owned subsidiary to the equity method for AGL
   Resources' joint venture interest in SouthStar. Prior to the formation of the
   SouthStar joint venture in July 1998, AGL Resources was engaged in a similar
   business through a wholly-owned subsidiary. Upon the formation of SouthStar,
   the customers and operations of the former wholly-owned subsidiary became the
   customers and operations of SouthStar. Prior to July 1998, the results of
   operations of the former wholly-owned subsidiary were reported on a
   consolidated basis. In contrast, the results attributable to AGL Resources'
   joint venture interest in SouthStar were accounted for using the equity
   method during fiscal 1999. AGL Resources' portion of SouthStar's results of
   operations is included in Other Income (Loss) on the Statements of
   Consolidated Income for the year ended September 30, 1999; and

 .  A decrease in Propane's operating revenue of $3.4 million due to lower sales
   attributable to warmer than normal weather during the winter months.

The decrease in non-utility operating revenues was partially offset by increased
revenues from Utilipro. During fiscal 1999, Utilipro provided integrated
customer care solutions to three certificated marketers in Georgia. The rapid
customer growth experienced by Georgia's certificated marketers during fiscal
1999 resulted in significant revenue growth for Utilipro. Utilipro's revenues
increased to $9.7 million in fiscal 1999 from $0.7 million in fiscal 1998.


Cost of Sales

Cost of sales for fiscal 1999 decreased to $544.7 million for fiscal 1999 from
$796.0 million for fiscal 1998, a decrease of 31.6%.

Utility. The utility's cost of sales decreased to $536.7 million for fiscal 1999
from $747.6 million for fiscal 1998. The decrease of $210.9 million in the
utility's cost of sales was primarily due to the following factors:

 .  A decrease of $247.5 million in the cost of gas sold to end-use customers
   resulting from customer migration to certificated marketers. AGLC recovered
   its actual gas costs, including carrying costs related to storage gas
   inventories, from its customers within the parameters of the January 26, 1999
   joint stipulation agreement with the GPSC;

 .  A decrease of $13.2 million associated with reduced levels of gas sold
   outside of the utility's distribution system; and

 .  A decrease of $12.7 million in cost of gas sold in Chattanooga as a result of
   weather that was warmer than the prior year.

These decreases were partially offset by an increase of $62.4 million resulting
from sales of gas inventory to certificated marketers.

Non-utility. Non-utility cost of sales decreased to $8.0 million for fiscal 1999
from $48.4 million for fiscal 1998. The decrease of $40.4 million was primarily
due to the following factors:

 .  A decrease of $36.6 million attributable to the change in accounting from
   consolidation of a wholly-owned subsidiary to the equity method for SouthStar
   as described above. (See Non-utility section under Operating Revenues.); and

 .  A decrease in Propane's cost of gas of $3.3 million due to lower sales
   attributable to warmer than normal weather during the winter months.


Operating Margin

Operating margin for fiscal 1999 decreased to $523.9 million from $542.6 million
for fiscal 1998, a decrease of 3.4%.

Utility. The utility's operating margin decreased to $502.5 million for fiscal
1999 from $527.2 million for fiscal 1998. The decrease of $24.7 million was
primarily due to the following factors as also discussed above in the Utility
section under Operating Revenues:

 .  A decrease of $38.6 million in delivery service revenue due to the loss of
   ancillary service revenues and certain transition revenues. Transition
   revenues decreased $15.8 million due to customer migration to certificated
   marketers. The remaining decrease of $22.8 million was primarily due to the
   timing of the implementation of the new SFV rate structure for AGLC delivery
   service that became effective during the fourth quarter of fiscal 1998. (See
   Overview of the Transition from a Regulated to a Competitive Business
   Environment section under Nature of Our Business.); and

 .  A decrease of $6.4 million in revenue associated with AGLC's IRP that was
   phased out during fiscal 1998. Previously, AGLC passed through to its
   customers, which was reflected in revenue on a dollar-for-dollar basis, IRP
   expenses incurred, which were also included in operating expenses. Therefore,
   the phase-out of IRP had no effect on net income.

                                                                              21
<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

These decreases were partially offset by:

 .  An increase in AGLC's late payment fee revenue from end-use customers of
   $13.5 million. The increase was primarily due to the late payment fee
   structure that became effective July 1, 1998 as part of the transition to
   competition. The late payment fee revenue is not expected to continue at the
   same level during fiscal 2000 since AGLC will no longer bill end-use
   customers; and

 .  AGLC recovered carrying costs related to storage gas inventories of $6.6
   million in fiscal 1999 from its customers within the parameters of the
   January 26, 1999 joint stipulation agreement with the GPSC and recorded these
   recovered carrying costs in operating revenue. During fiscal 1998, the
   recovered carrying costs from AGLC's customers of $5.4 million were recorded
   as other income. (See Note 2. Impact of Deregulation.)

Non-utility. Non-utility operating margin increased to $21.4 million for fiscal
1999 from $15.4 million for fiscal 1998, an increase of 39.0%. The increase is
primarily due to increased margins for Utilipro. Utilipro had increased revenues
of $9.0 million in fiscal 1999 as compared with fiscal 1998 due to the rapid
customer growth experienced by Georgia's certificated marketers. Because
Utilipro is a service company, its expenses are included in other operating
expenses. Therefore, the increase in operating revenues without a corresponding
increase in cost of sales resulted in the increase of operating margin for
fiscal 1999 as compared with fiscal 1998. The increase was partially offset by a
decrease of $1.4 million attributable to the change in accounting from
consolidation of a wholly-owned subsidiary to the equity method for SouthStar as
described above. (See Non-utility section under Operating Revenues.)


Total Other Operating Expenses

Total other operating expenses for fiscal 1999 decreased to $369.3 million from
$375.0 million for fiscal 1998, a decrease of 1.5%.

====================================================================================
</TABLE>

Utility. The utility's total other operating expenses for fiscal 1999 decreased
$3.7 million as compared with fiscal 1998 primarily due to the following
factors:

 .  A decrease of $6.7 million associated with non-cash, nonrecurring charges in
   fiscal 1998 including the write-off of the IRP asset of $3.1 million due to
   management's decision not to seek recovery for certain deferred expenses.
   Additionally, a loss of $3.6 million was reported as a result of the
   impairment of certain assets no longer useful primarily due to changes in the
   utility's information technology systems strategy;

 .  A decrease of $6.4 million in expenses associated with AGLC's IRP, which was
   phased out during fiscal 1998. Previously, AGLC passed through to its
   customers, on a dollar-for-dollar basis, IRP expenses incurred, which were
   included in operating expenses. Therefore, the phase-out of IRP had no effect
   on net income; and

 .  A decrease of $3.1 million in taxes other than income taxes primarily due to
   a decrease in assessed property values.

These decreases were partially offset by:

 .  An increase of $5.7 million in expenses primarily due to increased demand for
   customer service associated with the more rapid than expected pace of
   customer migration to certificated marketers;

 .  An increase of $3.7 million in depreciation and amortization expenses
   primarily due to increased depreciable property and increased depreciation
   rates for AGLC as ordered by the GPSC; and

 .  An increase of $2.6 million in maintenance expenses associated with AGLC's
   accelerated pipeline replacement program. (See AGLC Pipeline Safety Program
   section under State Regulatory Activity.)

Non-utility. Non-utility total other operating expenses for fiscal 1999
decreased $2.0 million as compared with fiscal 1998 primarily due to the
following factors:

 .  Nonrecurring charges of $7.2 million in fiscal 1998 associated with the
   impairment of certain assets; and

 .  Decreased operation expenses of $5.7 million for SouthStar due to the change
   in accounting from consolidation of a wholly-owned subsidiary to the equity
   method for SouthStar as described above. (See Non-utility section under
   Operating Revenues.)

22
<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

These decreases were partially offset by the following factors:

 .    Increased operation expenses of $12.0 million for fiscal 1999 as compared
     to fiscal 1998 for Utilipro resulting from increased demand for services as
     discussed above. (See Non-utility section under Operating Margin.); and

 .    Increased depreciation and amortization expenses of $4.0 million in fiscal
     1999 due to increases in depreciable property and depreciation rates for
     data processing equipment as ordered by the GPSC.

Other Income (Loss)

Other losses totaled $17.6 million for fiscal 1999 compared with other income of
$12.9 million for fiscal 1998. The decrease in other income of $30.5 million is
primarily due to:

 .    AGL Resources' portion of the loss for Sonat Marketing Company L.P. ("Sonat
     Marketing"), a joint venture in which, until August 12, 1999, AGL Resources
     owned a 35% interest. The loss by Sonat Marketing was the result of a
     combination of weather that was significantly warmer than in the prior year
     and charges recorded by Sonat Marketing throughout 1999. AGL Resources
     recorded a pre-tax loss related to its interest in Sonat Marketing of
     approximately $8.4 million for fiscal 1999, a decrease of $13.0 million as
     compared with pre-tax income of approximately $4.6 million for fiscal 1998;

 .    AGL Resources' portion of SouthStar's losses increased by $13.0 million
     primarily due to AGL Resources' portion of SouthStar's start-up costs of
     approximately $14.2 million for fiscal 1999, as compared to $1.2 million
     for fiscal 1998. The start-up costs are associated with establishing market
     share in Georgia's deregulated natural gas market; and

 .    The recovery from AGLC's customers in fiscal 1998 of $5.4 million in
     carrying costs related to storage gas inventories. During fiscal 1999, AGLC
     recovered carrying costs related to storage gas inventories of $6.6 million
     from its customers within the parameters of the January 26, 1999 joint
     stipulation agreement with the GPSC and recorded these recovered carrying
     costs in operating revenues.

Gain on Sales of Joint Venture Interests

During the fourth quarter of fiscal 1999, a pre-tax gain of $35.6 million was
recorded in connection with the sales of AGL Resources' joint venture interests
in Sonat Marketing and Sonat Power Marketing L.P. ("Sonat Power Marketing"). The
interests in Sonat Marketing and Sonat Power Marketing were sold for $40.0
million and $25.0 million, respectively.

Interest Expense

Interest expense decreased $1.4 million in fiscal 1999 compared with fiscal 1998
primarily due to decreased amounts of outstanding debt and decreased interest on
customer deposits of $0.6 million as a result of customer migration to
certificated marketers.

Dividends on Preferred Stock of Subsidiary

Dividends on preferred stock of subsidiary decreased $0.6 million in fiscal 1999
compared with fiscal 1998. The decrease was due to the redemption on December 1,
1997, of all of AGLC's 7.70% Series depositary preferred stock.

Income Taxes

Income taxes increased to $39.1 million for fiscal 1999 from $38.8 million for
fiscal 1998. The effective tax rate (income tax expense expressed as a
percentage of pre-tax income) for fiscal 1999 was 34.5% as compared to 32.5% for
fiscal 1998. The fiscal 1999 increases in income taxes and effective tax rate
were due primarily to the contribution of certain assets to a private charitable
foundation in fiscal 1998. This contribution resulted in a lower effective tax
rate for fiscal 1998. (See Note 3. Income Taxes.)

Net Income and Earnings per Common Share

Net income for fiscal 1999 was $74.4 million compared with $80.6 million in
fiscal 1998, a decrease of 7.7%. The decrease is primarily due to the following
factors:

 .    Decreased utility operating margin resulting from the migration of
     customers to certificated marketers;

 .    Loss of ancillary service and transition revenues without a corresponding
     reduction in operating costs;

 .    Decreased other income from operations resulting from AGL Resources' joint
     venture interests in Sonat Marketing and Sonat Power Marketing; and

 .    Start-up costs of SouthStar and Utilipro.

                                                                              23

Operating Revenues

Operating revenues for fiscal 1998 increased to $1,338.6 million from $1,287.6
million for fiscal 1997, an increase of 4.0%.

Utility. Utility operating revenues increased to $1,274.8 million for fiscal
1998 compared to $1,211.3 million for fiscal 1997. The increase of $63.5 million
in utility operating revenues was primarily due to the following factors:

 .    An increase in revenues in the fourth quarter due to the timing of the
     implementation of the new SFV rate structure that became effective July 1,
     1998, for AGLC's gas distribution services. (See Overview of the Transition
     from a Regulated to a Competitive Business Environment section under Nature
     of Our Business.);

 .    An increase of $31.2 million from gas sold outside of the utility's
     distribution system;

 .    An increase in gas sold due to an increase of approximately 35,000 in the
     average number of customers served; and

 .    An increase in gas sold due to weather that was 28.1% colder in 1998 than
     in 1997.

Non-utility. Non-utility operating revenues decreased to $63.8 million for
fiscal 1998 from $76.3 million for fiscal 1997. The decrease of $12.5 million
was primarily due to the change in accounting from consolidation of a wholly-
owned subsidiary to the equity method for AGL Resources' joint venture interest
in SouthStar. Prior to the formation of the SouthStar joint venture in July
1998, a wholly-owned subsidiary of AGL Resources was engaged in a similar
business. Upon the formation of SouthStar, the customers and operations of the
former wholly-owned subsidiary became the customers and operations of SouthStar.
The results of operations of the former wholly-owned subsidiary were reported on
a consolidated basis for the fiscal year ended September 30, 1997. In contrast,
the results attributable to AGL Resources' joint venture interest in SouthStar
were accounted for using the equity method during the fourth quarter of fiscal
1998. AGL Resources' portion of SouthStar's results of operations is included in
Other Income (Loss) on the Statements of Consolidated Income for the fourth
quarter of fiscal 1998.

Cost of Sales

Cost of sales for fiscal 1998 increased to $796.0 million from $766.5 million
for fiscal 1997, an increase of 3.8%.

Utility. The utility's cost of sales increased to $747.6 million for fiscal 1998
from $699.9 million for fiscal 1997. The increase of $47.7 million in the
utility's cost of sales was primarily due to the following factors:

 .    An increase in gas sold outside of the utility's distribution system;

 .    An increase in gas sold due to weather that was 28.1% colder in 1998 than
     in 1997; and

 .    An increase in gas sold due to an increase of approximately 35,000 in the
     average number of customers served.

Non-utility. Non-utility cost of sales decreased to $48.4 million for fiscal
1998 from $66.6 million for fiscal 1997. The decrease of $18.2 million was
primarily due to the change from consolidation of AGL Resources' wholly-owned
subsidiary to the equity method for AGL Resources' interest in SouthStar as
described above. (See Non-utility section under Operating Revenues.)

Operating Margin

Operating margin for fiscal 1998 increased to $542.6 million from $521.1 million
for fiscal 1997, an increase of 4.1%.

Utility. The utility's operating margin increased to $527.2 million for fiscal
1998 from $511.4 million in fiscal 1997.  The increase of $15.8 million was due
primarily to the following factors as described above in the Utility section
under Operating Revenues:

 .    Increased revenues in the fourth quarter of fiscal 1998 due to the timing
     of the implementation of the new SFV rate structure that became effective
     July 1, 1998, for AGLC's gas distribution service. (See Overview of the
     Transition from a Regulated to a Competitive Business Environment section
     under Nature of Our Business.);

 .    AGLE, which was formed in July 1996, produced a higher operating margin in
     fiscal 1998 than in fiscal 1997; and

 .    An increase of approximately 35,000 in the average number of customers
     served.

Non-utility. Non-utility operating margin increased to $15.4 million for fiscal
1998 from $9.7 million for fiscal 1997. The increase is primarily due to a
higher operating margin for Propane, reflecting a full twelve months' activity
for propane operations which were acquired during February and June, 1997.

Total Other Operating Expenses

Total other operating expenses for fiscal 1998 increased to $375.0 million from
$349.6 million for fiscal 1997, an increase of 7.3%.

                                  ==============================================

Utility. The utility's total other operating expenses for fiscal 1998 increased
$9.0 million as compared with fiscal 1997 primarily due to the following
factors:

 .    An increase of $6.7 million associated with non-cash, nonrecurring charges
     including the write-off of the IRP asset of $3.1 million due to
     management's decision not to seek recovery for certain deferred expenses.
     Additionally, a loss of $3.6 million was reported as a result of the
     impairment of certain assets no longer useful primarily due to changes in
     the utility's information technology systems strategy; and

 .    An increase of $2.6 million related to depreciation and amortization
     expenses primarily due to an increase in depreciable property.

Non-utility. The non-utility's total other operating expenses increased $16.4
million for fiscal 1998 as compared with fiscal 1997 primarily due to the
following factors:

 .    Marketing expenses of $3.7 million for SouthStar incurred in fiscal 1998
     prior to its formation;

 .    Increased operating expenses of $2.1 million for Propane reflecting a full
     twelve months activity for propane operations which were acquired during
     February and June, 1997; and

 .    Increased expenses of $7.2 million in fiscal 1998 associated with the
     impairment of certain assets.

Other Income (Loss)

Other income increased $2.6 million in fiscal 1998 compared with fiscal 1997
primarily due to increased income from AGL Resources' joint venture interests in
Sonat Marketing and Sonat Power Marketing.

Interest Expense

Interest expense increased $2.2 million in fiscal 1998 compared with fiscal 1997
primarily due to higher levels of outstanding long-term debt during fiscal 1998.
The increase was partially offset by less short-term interest expense due to
lower levels of outstanding short-term debt.

                                                                              25

Management's Discussion and Analysis of Results of Operations and Financial
Condition

Dividends on Preferred Stock of Subsidiaries

Dividends on preferred stock of subsidiary increased $0.5 million in fiscal 1998
compared with fiscal 1997. The increase was due to dividend requirements for a
full twelve-month period on the 8.17% Subsidiary Obligated Mandatorily
Redeemable Preferred Securities ("Capital Securities") with a principal amount
of $75.0 million. The Capital Securities were issued in June 1997. (See Note 7.
Preferred Stock.)

Income Taxes

Income taxes decreased to $38.8 million for fiscal 1998 from $46.8 million for
fiscal 1997 primarily due to a favorable resolution of certain outstanding tax
issues. Income tax reserves related to those issues were reduced, thereby
reducing income tax expense. Additionally, tax benefits associated with the
contribution of certain assets to a private charitable foundation resulted in a
decrease in the effective tax rate for fiscal 1998. The effective tax rate
(income tax expense expressed as a percentage of pre-tax income) for fiscal 1998
was 32.5% as compared to 38.0% for fiscal 1997. (See Note 3. Income Taxes.)

Net Income and Earnings per Common Share

Net income for fiscal 1998 was $80.6 million compared with $76.6 million in
fiscal 1997, an increase of 5.2%. The increase is primarily due to increased
operating margin and decreased income taxes resulting from the following
factors:

 .    Increased operating margin due to the timing of the implementation of the
     SFV rate structure that became effective July 1, 1998 for AGLC's gas
     distribution service. (See Overview of the Transition from a Regulated to a
     Competitive Business Environment section under Nature of Our Business.);
     and

 .    Increased operating margin due to an increase of approximately 35,000 in
     the average number of customers served during fiscal 1998.

These increases in operating margin were partly offset by higher operating
expenses resulting principally from charges associated with the impairment of
certain assets no longer useful primarily due to changes in AGL Resources'
information technology systems strategy. (See Note 1. Significant Accounting
Policies.)

Basic earnings per common share in fiscal 1998 were $1.41 compared with $1.37 in
fiscal 1997. The basic weighted average number of common shares outstanding
increased to 57.0 million from 56.1 million. Diluted earnings per common share
in fiscal 1998 were $1.41 compared with $1.36 in fiscal 1997. The diluted
weighted average number of common shares and common share equivalents
outstanding increased to 57.1 million from 56.2 million.

Financial Condition

Transition to Competition

The regulated rate structure under which AGLC has 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. Additionally, the regulated rate structure assumed that such
costs would be eliminated at the time the switch was made. This structure
therefore reduces the per customer revenue collected by AGLC in the month
following the transfer of a customer to a certificated marketer. However, AGLC's
experience has been that a significant portion of the costs associated with
customer service activities ("ancillary services"), including billing, bill
inquiry, payment processing and collection services, cannot be eliminated
immediately after a customer switch is made, as is assumed by the regulated rate
structure. Instead, a period of up to several months exists during which AGLC
continues to incur these expenses. As a result, a disparity now exists between
the speed at which AGLC is assumed for regulated rate design purposes to be
reducing costs and the speed at which AGLC actually is able to reduce costs.
During fiscal 1999, this disparity was exacerbated by the rapid pace at which
customers switched to certificated marketers.

The accelerated pace of customer migration to certificated marketers also has
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. In particular, beginning in
October 1998, and continuing each month thereafter, the number of customer calls
handled by the call centers significantly exceeded the number of customer calls
handled by the call centers during the same months of the preceding year. The
call center volumes increased 26% in

26
<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

fiscal 1999 as compared to fiscal 1998. As a result, AGLC increased its staffing
of customer service representatives and increased other call center related
expenses rather than reducing them, despite the fact that at September 30, 1999,
AGLC had approximately 82% fewer gas sales service customers than at September
30, 1998.

Customers are switched to certificated marketers on the first day of the month
following the receipt of a switch request.  At September 30, 1999, approximately
18% of the customers had not been switched to certificated marketers.  Such
customers were switched on October 1, 1999, with the exception of approximately
15,000 customers who are expected to switch during the first quarter of fiscal
2000. Therefore, as of October 1, 1999, almost all of AGLC's remaining customers
were receiving service from certificated marketers. AGLC's annual delivery
service revenues for fiscal 1999 associated with providing ancillary services
and certain transition revenues were reduced by approximately $38.6 million as
compared to fiscal 1998; however, associated costs were not reduced by the same
amount, resulting in an adverse effect on net income. Transition revenues
decreased $15.8 million due to customer migration to certificated marketers. The
remaining decrease of $22.8 million was primarily due to the timing of the
implementation of the new SFV rate structure for AGLC delivery service that
became effective during the fourth quarter of fiscal 1998. The impact of the
revenue and cost imbalance related to the transition to competition is expected
to continue into fiscal 2000.

AGLC is pursuing solutions to this revenue and cost imbalance aggressively,
including reducing or eliminating costs as quickly as possible, consistent with
prudent business practices, and increasing employee productivity at customer
call centers. The Deregulation Act authorizes an electing distribution company,
like AGLC, to recover prudently incurred costs that are "stranded" as a result
of the transition to competition. 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 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.

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 for its services. In contrast, at September 30, 1999,
AGLC billed 15 certificated marketers in Georgia for services, that in turn bill
the 1.4 million end-use customers. As a result of deregulation, AGLC now bills
certificated marketers for intrastate delivery and other services and no longer
has recourse to end-use customers for collection.

As of September 30, 1999, 25.8% of AGL Resources' total gas receivables were due
from 7 of the 15 certificated and active marketers and 58.7% were due from end-
use customers in Georgia who migrated to certificated marketers late in the
fiscal year or who were randomly assigned. In fiscal 2000, only gas receivables
attributable to Chattanooga will be due from end-use customers. As a result, at
September 30, 2000, a significantly higher percentage of AGL Resources' total
gas receivables will be due from Georgia certificated marketers.

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
September 30, 1999, AGL Resources' total gas receivables included approximately
$6.8 million attributable to Peachtree.  As of September 30, 1999, AGLC held
financial surety bonds totaling $11 million as security for Peachtree's
obligations. As of the date of Peachtree's bankruptcy filing, Peachtree owed
AGLC approximately $14.2 million and AGLC continued to hold the $11 million of
surety bonds. The amount owed to AGLC does not include amounts owed by Peachtree
to interstate pipelines for assigned capacity. Based upon information filed by
Peachtree in its bankruptcy proceeding, as of the date of Peachtree's filing,
Peachtree owed interstate pipelines approximately $1.8 million for assigned
capacity. On November 17, 1999, Peachtree entered into an agreement to sell its
customers and storage gas inventories to another certificated marketer. This
sale is expected to close prior to December 31, 1999.

                                                                              27
<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

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 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 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.

Management does not believe that AGLC's concentration of credit risk or that
Peachtree's bankruptcy filing will have a material adverse effect on AGL
Resources' results of operations or financial condition.

Financing Activity

Capital Securities

In June 1997, AGL Resources established AGL Capital Trust I (the "Trust"), a
Delaware business trust. The Trust issued two types of securities. Common voting
securities were issued to AGL Resources. In addition, the Trust issued and sold
$75.0 million principal amount of 8.17% Capital Securities to certain initial
investors. The Trust used the proceeds to purchase 8.17% Junior Subordinated
Deferrable Interest Debentures, which are due June 1, 2037, from AGL Resources.

The Capital Securities are subject to mandatory redemption at the time of the
repayment of the Junior Subordinated Debentures on June 1, 2037, or the optional
prepayment by AGL Resources after May 31, 2007.

AGL Resources fully and unconditionally guarantees all of the Trust's
obligations for the Capital Securities. AGL Resources used the net proceeds of
approximately $74.0 million from the sale of the Junior Subordinated Debentures
to repay short-term debt, to redeem some of AGLC's outstanding issues of
preferred stock, and for other corporate purposes.

AGLC Preferred Securities

On August 15, 1997, AGLC fully redeemed the following:

 .  4.5% Cumulative Preferred Stock;
 .  4.72% Cumulative Preferred Stock;
 .  5.0% Cumulative Preferred Stock;
 .  7.84% Cumulative Preferred Stock; and
 .  8.32% Cumulative Preferred Stock.

The issues of preferred stock were redeemed, at the call price in effect for
each issue, for a total of $14.7 million.

On December 1, 1997, AGLC redeemed all of its outstanding 7.70% Series
depositary preferred stock.

Common Stock

The following shares of common stock have been issued:

 .  677,411 shares in fiscal 1999;
 .  739,380 shares in fiscal 1998; and
 .  753,866 shares in fiscal 1997.

The shares of common stock were issued under ResourcesDirect, a direct stock
purchase and dividend reinvestment plan; the Retirement Savings Plus Plan; the
Long-Term Stock Incentive Plan; the Nonqualified Savings Plan; and the Non-
Employee Directors Equity Compensation Plan.

The issuances increased common stockholders' equity by the following amounts:

 .  $11.7 million in fiscal 1999;
 .  $12.9 million in fiscal 1998; and
 .  $13.8 million in fiscal 1997.

Subsequent to June 15, 1999, shares issued under the above plans have been
issued from shares held in treasury.

Termination of LESOP

As a result of the termination of the Leveraged Employee Stock Ownership Plan
("LESOP"), AGL Resources distributed the value of participants' LESOP account
balances as of June 15, 1999. At the election of the participants, AGL Resources
distributed the value of each account in one of three forms:

 .  Direct rollover into the Retirement Savings Plus Plan ("401(k) Plan") or into
   another tax-qualified retirement plan;

 .  Lump sum payment in the form of a certificate for shares of AGL Resources
   common stock; or

 .  Lump sum cash payment of $18.50 per share.

As of June 15, 1999, 868,688 LESOP shares were repurchased by AGL Resources in
cash from the LESOP trustees in a non-brokered transaction at a purchase price
of $18.50 per share and are held as treasury shares. An additional 236,625
shares were transferred to participants' accounts under the 401(k) Plan from the
respective participants' accounts in the LESOP.

(1)  Fixed charges consist of interest on short-term and long-term debt, other
     interest, and the estimated interest components of rentals.
(2)  Interest charges exclude the debt portion of allowance for funds used
     during construction.

Long-Term Debt

AGL Resources did not issue long-term debt during fiscal 1999 or 1998. The
current portion of long-term debt as of September 30, 1999 is $50.0 million of
Series A and Series B medium-term notes with interest rates ranging from 7.15%
to 9.10%.

Short-Term Debt

Short-term debt primarily is utilized to meet working capital requirements. In
addition, capital expenditures are funded temporarily with short-term debt.
Lines of credit with various banks provide for direct borrowings and are subject
to annual renewal. The current lines of credit vary from $180.0 million to
$260.0 million.

Short-term debt decreased $75.0 million to $1.5 million as of September 30,
1999, from $76.5 million as of September 30, 1998. The decrease in short-term
debt was primarily due to the assignment of natural gas inventories to
certificated marketers since AGLC no longer sells natural gas to end-use
customers. Additionally, AGL Resources expects to be less dependent on short-
term debt since it will have no need to replenish the natural gas inventories.
(See Inventory Assignment section under State Regulatory Activity and Note 9.
Short-Term Debt.)

Capital Requirements

Capital expenditures for construction of distribution facilities, purchase of
equipment, and other general improvements were $143.4 million during fiscal 1999
as compared to $117.3 million during fiscal 1998. The increase of $26.1 million
was primarily due to capital expenditures incurred in fiscal 1999 for the
pipeline replacement program. The increase was partially offset by decreased
capital expenditures for data processing equipment. The pipeline replacement
program costs will be recovered by AGLC pursuant to a regulatory mechanism
approved by the GPSC. (See AGLC Pipeline Safety Program section under State
Regulatory Activity.)

Typically, funding for capital expenditures is provided through a combination of
internal sources, the issuance of short-term and long-term debt, and the
issuance of equity securities. AGL Resources' estimated aggregate capital
requirement for the next three years, ending on September 30, 2002, is
approximately $471.8 million, of which approximately $154.8 million is
attributable to the pipeline replacement program approved by the GPSC.

                                                                              29

Management's Discussion and Analysis of Results of Operations and Financial
Condition

As of September 30, 1999, natural gas stored underground decreased $90.8 million
to $47.3 million from $138.1 million, primarily due to the assignment of natural
gas inventories to certificated marketers in accordance with the Deregulation
Act. As of October 1, 1999, AGLC's natural gas stored underground decreased
approximately $19.0 million, primarily due to the additional assignment of
natural gas inventories to certificated marketers. (See Inventory Assignment
section under State Regulatory Activity.)

Ratios and Coverages

As of September 30, 1999, AGL Resources' capitalization ratio consisted of:

 .  45.3% long-term debt;
 .  5.5% preferred securities; and
 .  49.2% common equity.

The return on average common stockholders' equity decreased in fiscal 1999 from
fiscal 1998 as a result of the decrease in net income of $6.2 million.

The ratio of earnings to combined fixed charges and preferred stock dividends,
the ratio of earnings to interest charges and preferred stock dividends, and the
ratio of earnings to fixed charges decreased in fiscal 1999 compared to fiscal
1998 primarily due to lower earnings.


State Regulatory Activity

During fiscal 1999, AGLC unbundled, or separated, all services to its natural
gas customers in Georgia; allocated delivery capacity to certificated marketers
who sell the gas commodity to residential and small commercial customers; and
created a secondary market for large commercial and industrial transportation
capacity. (See Overview of the Transition from a Regulated to a Competitive
Business Environment section under Nature of Our Business.)


Daily Balancing Services; EBB.  In September 1999, the GPSC approved the
application of daily balancing services and related charges to certificated
marketers serving retail customers on AGLC's system. This decision allows AGLC
to operate its delivery system in a reliable manner and provides for full
recovery of costs incurred for system imbalances. Along with the GPSC's order on
daily balancing, AGLC's Electronic Bulletin Board ("EBB") was declared fully
operational. This declaration was a requirement in order for daily balancing to
become effective.

Regulatory Accounting. AGL Resources has recorded regulatory assets and
liabilities in its 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.

The Deregulation Act allows deregulation of natural gas sales and the separation
of some ancillary services of local natural gas distribution companies. However,
the rates that AGLC, as the local gas distribution company, charges to transport
natural gas through its intrastate pipeline system will continue to be regulated
by the GPSC. Therefore, the continued application of SFAS 71 is appropriate for
regulatory assets and liabilities related to AGLC's delivery services.

AGLC Pipeline Safety Program. 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.

During fiscal 1999, approximately 247 miles of pipe was replaced pursuant to the
program. Also during fiscal 1999, AGLC's capital expenditures and operation and
maintenance expenses related to the pipeline replacement program were
approximately $43.2 million and $11.5 million, respectively. All such amounts
will be recovered through a combination of SFV rates and a regulatory mechanism.

Weather Normalization. The weather normalization adjustment rider ("WNAR")
authorized by the TRA to offset the impact of unusually cold or warm weather on
customer billings and operating margin remains in effect for Chattanooga. The
WNAR in  effect for AGLC was discontinued for fiscal 1999 by the GPSC when the
SFV rate structure became effective. (See Note 1. Significant Accounting
Policies.)

Management's Discussion and Analysis of Results of Operations and Financial
Condition

Inventory Assignment. Pursuant to the Deregulation Act, certificated marketers,
including AGLC's marketing affiliate, began selling natural gas to firm end-use
customers at market-based prices in November 1998. Part of the unbundling
process is the allocation of certain pipeline services that AGLC has under
contract, including interstate pipeline transportation and gas storage. In
particular, AGLC has allocated the majority of its pipeline storage services
that it has under contract to the certificated marketers along with a
corresponding amount of inventory based on the respective market share of the
certificated marketers. Following the rules of AGLC's tariff, the sale price was
the weighted-average cost of the storage inventory at the time of sale. AGLC
changed its inventory costing method for its gas inventories from first-in,
first-out to weighted average effective October 1, 1998. The weighted-average
cost-flow assumption provides for a more equitable pricing method for the sale
of gas inventories to certificated marketers.

As of September 30, 1999, AGLC had $43.0 million in gas storage. This amount
represents:

 .  Unassigned gas storage as of September 30, 1999, to serve unassigned
   customers; and

 .  AGLC's retained storage, that represents the under ground storage capacity
   retained by AGLC to balance temporary differences between marketer's expected
   demand and actual demand.

Certain gas storage inventory was unassigned at September 30, 1999 because all
customers had not been assigned.  Customers are switched to certificated
marketers on the first day of the month following the receipt of a switch
request. At September 30, 1999, approximately 18% of the customers had not been
switched to certificated marketers.  Such customers were switched on October 1,
1999, with the exception of approximately 15,000 customers. The remaining
customers are expected to switch during the first quarter of fiscal 2000. The
resulting decrease in gas inventory on October 1, 1999 was approximately $19.0
million.


Gas Supply Contracts

In connection with AGLC's exit from natural gas sales service, AGLC terminated
24 long-term gas supply contracts. Certain of these contracts will require the
payment of an aggregate of approximately $2.0 million of reservation charges in
order to terminate the contracts. AGLC was permitted by the GPSC to utilize gas
cost credits to pay these reservation charges. (See Note 10. Commitments and
Contingencies.)


Federal Regulatory Activity

FERC Order 636: Transition Costs Settlement Agreements. The utility purchases
natural gas transportation and storage services from interstate pipeline
companies, and the Federal Energy Regulatory Commission ("FERC") regulates those
services and the rates the interstate pipeline companies charge the utility.
During the past decade, the FERC has dramatically transformed the natural gas
industry through a series of generic orders promoting competition in the
industry. As part of that transformation, the interstate pipelines that serve
the utility have been required to:

 .  Unbundle, or separate, their transportation and gas supply services; and

 .  Provide a separate transportation service on a nondiscriminatory basis for
   the gas that is supplied by numerous gas producers or other third parties.

The FERC is considering further revisions to its rules, including the following:

 .  Its policies governing secondary market transactions for use of pipeline
   capacity; and

 .  Revisions that would 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 whether revisions will be adopted or how they 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 September 30, 1999, approximately $105.8 million of those costs
had been incurred and were being recovered primarily from the utility's
customers under rates charged for gas sales. Going forward, AGLC's remaining
costs will be recovered from certificated marketers.

The largest portion of the transition costs the utility must pay consists of gas
supply realignment costs that Southern Natural Gas Company ("Southern") and
Tennessee Gas Pipeline Company ("Tennessee") bill the utility. The utility and
other parties have entered restructuring settlements with Southern and Tennessee
that resolve all transition cost issues for those pipelines.

                                                                              31
<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

Under the Southern settlement, the utility's share of Southern's transition
costs is approximately $89.7 million, of which the utility incurred $87.6
million as of September 30, 1999. Under the Tennessee settlement, the utility's
share of Tennessee's transition costs was approximately $14.7 million, all of
which had been incurred by September 30, 1999.

Southern filed a general rate case on September 1, 1999.  Its proposed rates
would represent a 10% increase (about $15 million per year) under AGLC's
existing contracts in firm interstate pipeline charges. These rates would become
effective March 1, 2000, subject to refund unless the FERC should accept an
offer of settlement between Southern and its customers.  Such a settlement is
currently under discussion.

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 twelve 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 used the following process for the estimates:
First, AGLC eliminated the sites where it was believed that no cleanup or
further investigation was likely to be necessary. Second, AGLC estimated its
likely future cost of investigation and cleanup at each of the remaining sites.
Third, for some sites, AGLC estimated its likely "share" of the costs. AGLC
developed its estimate based on any agreements for cost sharing it has, the
legal principles for sharing costs, its evaluation of other entities' ability to
pay, and other similar factors.

Using the above process, AGLC currently estimates that its total future cost of
investigating and cleaning up 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.
Consequently, AGLC has recorded the lower end of the range, or $102.4 million,
as a liability and a corresponding regulatory asset as of September 30, 1999.
AGLC does not believe that any single number within the range constitutes a
"better" estimate because its actual future investigation and cleanup costs will
be affected by a number of contingencies that cannot be quantified at this time.
During fiscal 1999, the asset increased $78.7 million and was reduced by
amortization of $6.1 million resulting in an asset of $150.2 million.

As of September 30, 1998, AGLC had recorded a liability of $47.0 million.
During fiscal 1999, the liability increased by $78.7 million and payments of
$23.3 million were made. The net increase in the liability was $55.4 million
resulting in a liability of $102.4 million as of September 30, 1999. The net
increase in the liability was based on revised estimates of future costs, which
resulted in a corresponding increase in the unrecovered environmental response
cost asset.

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. During fiscal 1999, AGLC
recovered $6.1 million through its environmental response recovery rider. (See
Note 12. Environmental Matters.)

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 fiscal 1999 or 1998.

Accounting Developments

During fiscal 1999, AGL Resources adopted the Financial Accounting Standards
Board ("FASB") Statements No. 130, "Reporting Comprehensive Income",  No. 131,
"Disclosure about Segments of an Enterprise and Related Information", and No.
132, " Employers' Disclosures about Pensions and Other Postretirement Benefits".
None of these statements had a material effect on the consolidated financial
statements.

In June 1998, the FASB 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

32


<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

derivative instruments, including certain derivative instruments embedded in
other contracts, and for hedging activities. AGL Resources will adopt SFAS 133
in fiscal 2001. The impact of SFAS 133 on AGL Resources' consolidated financial
statements is under review and is currently unknown.

Competition

Utility

The utility competes with alternative energy suppliers to distribute natural gas
to large commercial and industrial customers. Those customers can switch to
alternative fuels, including propane, fuel and waste oils, electricity and, in
some cases, combustible wood by-products. AGLC also competes to distribute gas
to large commercial and industrial customers who seek to bypass AGLC's
distribution system.

Pursuant to the GPSC's rate case order of June 30, 1998, AGLC has been able to
price distribution services to large commercial and industrial customers in one
of three ways:

 .  GPSC approved rates in AGLC's tariff;

 .  Negotiated rates if an existing rate is not priced competitively with a
   customer's competitive alternative fuel; or

 .  Special contracts approved by the GPSC.

Additionally, interruptible customers have the option of purchasing delivery
service directly from certificated marketers, who are authorized to use capacity
on AGLC's distribution system that is allocated to the certificated marketers
for firm residential and small commercial customers, whenever such capacity is
not being used for firm customers.

Non-utility

AGL Resources engages in several competitive, energy-related businesses,
including gas supply services, wholesale and retail propane sales, customer care
services, and the sale of energy-related products and services for residential,
commercial, and industrial customers throughout the Southeast. (See
Organizational Structure section under Nature of Our Business.)

Unlike the utility, the non-utility businesses are not regulated. The non-
utility businesses typically face competition from other companies in the same
or similar businesses.

SouthStar competes with other energy marketers, including certificated marketers
in Georgia, to provide natural gas and related services to customers in Georgia
and the Southeast. SouthStar began marketing natural gas to all customers in
Georgia during the first quarter of fiscal 1999. Marketing efforts during the
transition to competition in Georgia consisted of advertising and promotional
campaigns. As of October 1, 1999, SouthStar had the largest market share among
approximately 15 certificated and active marketers in Georgia.

Utilipro competes with other customer care service providers throughout the
United States and Canada. Utilipro anticipates that the number of competitors
will increase as energy markets in the United States and Canada become
deregulated.

Year 2000 Readiness Disclosure

The widespread use by governments and businesses, including AGL Resources, of
computer software that relies on two digits, rather than four digits, to define
the applicable year may cause computers, computer-controlled systems, and
equipment with embedded software to malfunction or incorrectly process data as
AGL Resources approaches and enters the year 2000.

AGL Resources' Year 2000 Readiness Initiative

In view of the potential adverse impact of the "Year 2000" issue on its
business, operations, and financial condition, AGL Resources has established a
cross-functional team to coordinate, and to report to management on a regular
basis about, the assessment, remediation planning, and plan implementation
processes directed to the Year 2000 issue. AGL Resources has also engaged
independent consultants to assist in the assessment, remediation, planning, and
implementation phases of our Year 2000 initiative. AGL Resources' Year 2000
initiative is proceeding on a schedule that management believes will achieve
Year 2000 readiness in a timely manner.

The mission of AGL Resources' Year 2000 initiative is to define and provide a
continuing process for assessment, remediation planning, and plan implementation
to achieve a level of readiness that will meet the challenges presented by the
Year 2000 in a timely manner. Achieving Year 2000 readiness does not mean
correcting every Year 2000 limitation. Achieving Year 2000 readiness does mean
that critical systems, critical electronic assets, and relationships with key
business partners have been evaluated and are expected to be suitable for
continued use into and beyond the year 2000, and that contingency plans are in
place.

                                                                              33


<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

AGL Resources' Year 2000 readiness initiative involves a three-phase process.
The initiative is a continuing process with all phases of the initiative
progressing concurrently with respect to information technology ("IT")
applications, infrastructure and non-information technology ("non-IT")
applications, as each of those terms is defined below, and key business
relationships. The three phases of AGL Resources' Year 2000 initiative are as
follows:

1. Assessment - Assessment involves identifying and inventorying business assets
   and processes. It also involves determining the Year 2000 readiness status of
   AGL Resources' assets and of key business partners. Key business partners are
   those customers, suppliers and manufacturers who management believes may be
   material to AGL Resources' business, results of operations, or financial
   condition. In appropriate circumstances, pre-remediation testing is conducted
   as a part of the assessment phase. The assessment phase of AGL Resources'
   Year 2000 initiative includes assessment for Year 2000 readiness of
   the following:

     .  IT applications - Computer software maintained by AGL Resources'
        Information Systems ("IS") Department;

     .  Non-IT applications - Computer hardware, such as AGL Resources'
        mainframe and PC's, microprocessors embedded in equipment, and software
        maintained by business units other than AGL Resources' IS Department;
        and

     .  Key business partners (customers, suppliers, and manufacturers).

2. Preparation of Remediation Plans - The purpose of this phase is to develop
   plans which, when implemented, will enable assets and business relationships
   to be Year 2000 ready. This phase involves implementation planning and
   prioritizing the implementation of remediation plans.

3. Implementation - This step involves the implementation of remediation plans,
   including post-remediation testing and contingency planning.


State of Readiness

AGL Resources continues to assess the impact of the Year 2000 issue throughout
its businesses and operations, including its customer and supplier base. The
scope of the Year 2000 initiative includes AGL Resources and its subsidiaries.

Set forth below is a description of the progress of AGL Resources' Year 2000
initiative in all business units that are within the scope of AGL Resources'
Year 2000 initiative, with the exception of SouthStar and of Utilipro. With
respect to SouthStar, the assessment, remediation planning, and plan
implementation phases have been completed. All of SouthStar's critical assets
are Year 2000 ready. An assessment of the readiness of SouthStar's two joint
venture partners is underway. Information or responses from all of SouthStar's
key suppliers and customers has been obtained. The assessment of SouthStar's key
suppliers reveals that all are Year 2000 ready, with the exception of one
supplier whom SouthStar expects will achieve Year 2000 readiness prior to
December 31, 1999. The preparation and review of contingency plans for SouthStar
have been completed. With respect to Utilipro, the Year 2000 initiative
commenced in January of 1999. The project plan and assessment phase, as well as
the remediation planning phase, for the Utilipro Year 2000 initiative have been
completed. Utilipro has engaged independent consultants to assist with its Year
2000 initiative. The mission and processes of the Year 2000 initiative for
Utilipro are essentially identical to those of AGL Resources' Year 2000
initiative. The majority of the remediation and testing for Utilipro is
complete. Management expects Utilipro's business and operations to achieve Year
2000 readiness.


IT Applications

Assessment of, and remediation planning for, IT applications is complete and
implementation is underway. During the assessment phase, an assessment of AGL
Resources' 81 IT applications was completed. Of the 81 applications, 14 are
deemed to be critical applications. The results of AGL Resources' Year 2000
initiative with respect to IT applications indicate that, to date:

 .  55 applications now are ready for Year 2000, including all critical
   applications;

 .  Nine applications have been eliminated;

 .  Sixteen applications have been replaced; and

 .  One application is scheduled for elimination by December 15, 1999.

34
<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

Infrastructure and Non-IT Applications

Assessment, remediation, and testing of infrastructure and non-IT applications
are complete. These processes involved:

 .  Identifying business processes;

 .  Identifying the assets that comprise the infrastructure and non-IT
   applications category, and defining the business process or processes to
   which such assets relate;

 .  Identifying the mission criticality of each such asset and business process;

 .  Documenting in a tracking database the existence, and the mission-
   criticality, of each such asset and business process;

 .  Fixing, upgrading, replacing, eliminating, or developing alternate processes
   for those assets that were deemed not to be Year 2000 ready; and

 .  Testing the mission-critical assets where possible. In those cases where
   testing of those assets was not possible or was cost-prohibitive, the process
   involved evaluating and accepting, where appropriate, the readiness
   statements provided by the manufacturers of such assets.


Key Business Partners

AGL Resources has contacted key business partners, including suppliers,
manufacturers and customers to evaluate their Year 2000 readiness plans and
status of readiness. AGL Resources has contacted over 2,000 suppliers and
manufacturers by letter. This group includes suppliers and manufacturers that
AGL Resources considers key business partners as well as other selected
suppliers and manufacturers. AGL Resources has received responses from the
majority of suppliers and manufacturers who were contacted. To date, AGL
Resources has completed follow-up with 100% of those suppliers that are
considered critical suppliers. AGL Resources plans to continue to update its
assessment of the readiness of critical suppliers and manufacturers during the
remainder of calendar year 1999.

AGL Resources also initiated contact with more than 2,500 commercial and
industrial customers by personal or telephone interview or by fax survey. That
group of customers includes customers that AGL Resources considers key business
partners as well as other selected customers. AGL Resources expects to continue
to follow-up as needed throughout the remainder of calendar year 1999. In light
of deregulation, the expected focus of AGL Resources' follow-up effort will be
on certificated marketers in Georgia who are also AGLC's customers.

AGL Resources is assessing the state of readiness of key business partners who
have responded to requests for information and will continue to do so as
additional responses are received. As a general matter, AGL Resources, like
other businesses, is vulnerable to key business partners' inability to achieve
Year 2000 readiness. AGL Resources cannot predict the outcome of business
partners' readiness efforts. However, AGL Resources has developed contingency
plans to mitigate risks associated with the Year 2000 readiness of certain
business partners, including certain key business partners. AGL Resources'
review of key business partners' responses gives management no reason to believe
the Year 2000 readiness of key business partners is likely to have a material
impact on AGL Resources' business, results of operations, or financial
condition. AGL Resources will continue to assess key business partners
throughout the remainder of calendar year 1999.


Costs to Address Year 2000 Issues

AGL Resources intends to devote the resources necessary to achieve a level of
readiness that will meet its Year 2000 challenges in a timely manner. Through
September 30, 1999, cumulative expenses in connection with AGL Resources' Year
2000 assessment, remediation planning, and plan implementation processes were
approximately $6.7 million. Of this total, $2.7 million was spent in fiscal
years 1997 and 1998. Through September 30, 1999, an additional $8.6 million has
been spent for the replacement of AGL Resources' financial and human resources
information systems. The primary reason for replacing those systems was to
achieve increased efficiency and functionality. An added benefit of replacing
those systems was the avoidance of the costs of remediating Year 2000 problems
associated with AGL Resources' previous financial and human resources
information systems. The costs of the new financial and human resources
information systems have been capitalized, in accordance with AGL Resources'
accounting policies and with generally accepted accounting principles.

AGL Resources expects to spend $2.1 million for the Year 2000 initiative in
fiscal 2000. These estimates include costs associated with the use of outside
consultants as well as hardware and software costs. They also include direct
costs associated with employees of AGL Resources' IS Department who work on the
Year 2000 initiative. It does not include costs associated with employees of
other departments such as Legal and Internal Audit, and of other business units,
that are involved, on a limited basis, in the Year 2000 initiative.

                                                                              35
<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

On June 30, 1998, the GPSC issued a rate case order in response to a filing by
AGLC. The GPSC provided for the deferral, amortization, and recovery of some
Year 2000 costs over a five-year period beginning July 1, 1998. The portion of
those costs that will be deferred in this way includes costs which would
normally be expensed in accordance with generally accepted accounting principles
and that are attributable to AGLC. Going forward, AGL Resources estimates that
approximately 83% of Year 2000 costs will be attributable to AGLC. At September
30, 1999, AGLC had deferred total costs of approximately $4.4 million, which are
being amortized and recovered over a five year period.

At present, the cost estimates associated with achieving Year 2000 readiness are
not expected to materially impact AGL Resources' consolidated financial
statements. AGL Resources will account for costs related to achieving Year 2000
readiness in accordance with its internal accounting policies, with regulatory
treatment, and with generally accepted accounting principles.


Risks of Year 2000 Issues

AGL Resources has finalized its estimate of the Year 2000 most reasonably likely
worst case scenarios. These scenarios contemplate intermittent disruptions of
important goods and services that AGL Resources obtains from third parties at
some locations. AGL Resources does not expect these disruptions to be long-term
nor does AGL Resources expect the disruptions to materially impact its
operations as a whole. However, the extent of such disruptions is uncertain, and
if the extent or longevity of the disruptions exceed AGL Resources' assumptions,
they could have a material adverse impact on AGL Resources' business, results of
operations, or financial condition.

Although AGL Resources has finalized its estimate of Year 2000 most reasonably
likely worst case scenarios, the process of refining AGL Resources' most
reasonably likely worst case scenarios will be an ongoing process. AGL Resources
expects to continue to develop and modify its most reasonably likely worst case
scenarios as AGL Resources obtains additional information regarding (a) internal
systems and equipment during the implementation phase of its Year 2000
initiative as well as during independent validation and verification of the Year
2000 readiness of such systems and equipment, and (b) the status, and the impact
on AGL Resources, of the Year 2000 readiness of others.


Business Continuity and Contingency Planning

AGL Resources has completed its Year 2000 contingency plans. Those plans, which
are intended to enable AGL Resources to deliver an acceptable level of service
despite Year 2000 failures, include performing certain processes manually,
changing suppliers, and reducing or suspending certain noncritical aspects of
AGL Resources' operations. AGL Resources' contingency planning effort focused on
the potential internal risks as well as potential risks associated with AGL
Resources' suppliers and customers. AGL Resources' most reasonably likely worst
case scenarios as described above define the boundaries of AGL Resources'
contingency planning effort. The contingency planning process also includes, but
is not limited to the following:

 .  Identifying the nature of Year 2000 risks in order to understand the business
   impact of those risks;

 .  Identifying minimal acceptable service levels;

 .  Identifying alternative providers of goods and services;

 .  Identifying necessary investments in additional back-up equipment such as
   generators and communications equipment; and

 .  Developing manual methods of performing critical functions currently
   performed by electronic systems and equipment.

AGL Resources has completed initial testing of its contingency plans. During the
remainder of calendar year 1999, AGL Resources plans to update, refine, and
further test its contingency plans as needed, to reflect system and business
changes as they evolve.


Clean Management

Clean management describes the process of:

 .  Identifying AGL Resources' means of acquiring assets and of developing or
   modifying systems;

 .  Verifying the Year 2000 readiness of assets prior to purchase; and

 .  Assuring that system modifications and new systems are Year 2000 ready at the
   time of development or acquisition.

AGL Resources is using the clean management process on an on-going basis. Clean
management applies to IT applications, to infrastructure and non-IT
applications, and to key business partner relationships. AGL Resources expects
to obtain additional or updated information about the Year 2000

36
<PAGE>

Management's Discussion and Analysis of Results of Operations and Financial
Condition

readiness of assets and key business partners through the clean management
process. AGL Resources will address any additional Year 2000 issues discovered
as a result of the clean management process.


Validation and Verification

AGL Resources' Year 2000 initiative includes validation and verification of
assets by AGL Resources, by third parties, or by both. AGL Resources expects
validation and verification efforts, whether internal or independent, to result
in the discovery of additional Year 2000 issues and AGL Resources will address
those issues as they arise. AGL Resources expects the validation and
verification process to continue throughout calendar year 1999 and into calendar
year 2000.

Presently, AGL Resources believes that its assessment, remediation planning,
plan implementation and contingency planning processes will be effective to
achieve Year 2000 readiness in a timely manner.


Forward-Looking Statements

The preceding "Year 2000 Readiness Disclosure" discussion contains various
forward-looking statements that represent AGL Resources' beliefs or expectations
regarding future events. When used in the "Year 2000 Readiness Disclosure"
discussion, the words "believes", "intends", "expects", "estimates", "plans",
"goals" and similar expressions are intended to identify forward-looking
statements. Forward-looking statements include, without limitation, AGL
Resources' expectations as to when AGL Resources will complete the assessment,
remediation planning, and implementation phases of its Year 2000 initiative as
well as its Year 2000 contingency planning; AGL Resources' estimated cost of
achieving Year 2000 readiness; and AGL Resources' belief that its internal
systems and equipment will be Year 2000 ready in a timely and appropriate
manner. All forward-looking statements involve a number of risks and
uncertainties that could cause actual results to differ materially from
projected results. Factors that may cause those differences include availability
of information technology resources; customer demand for AGL Resources' products
and services; continued availability of materials, services, and data from AGL
Resources' suppliers; the ability to identify and remediate all date-sensitive
lines of computer code and to replace embedded computer chips in affected
systems and equipment; the failure of others to timely achieve appropriate Year
2000 readiness; and the actions or inaction of governmental agencies and others
with respect to Year 2000 problems.

Notes to Consolidated Financial Statements

Note 1. Significant Accounting Policies

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

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 which 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 operations
expenses include costs allocated from AGL Resources Inc.

AGL Resources currently owns or has an interest in the following non-utility
businesses:

 .  SouthStar Energy Services LLC ("SouthStar"), a joint venture among a
   subsidiary of AGL Resources Inc. and subsidiaries of Dynegy, Inc. and
   Piedmont Natural Gas Company. SouthStar markets natural gas and related
   services to residential and small commercial customers in Georgia and to
   industrial customers in the Southeast. SouthStar began marketing natural gas
   to customers in Georgia during the first quarter of fiscal 1999 under the
   trade name "Georgia Natural Gas Services";

 .  AGL Investments, Inc., which currently manages certain non-utility businesses
   including:

   .  AGL Propane, Inc. ("Propane"), which engages in the sale of propane and
      related products and services in Georgia, Alabama, Tennessee and North
      Carolina;

   .  Trustees Investments, Inc., which owns Trustees Gardens, a residential and
      retail development located in Savannah, Georgia; and

   .  Utilipro, Inc., ("Utilipro"), in which AGL Resources has an 85% ownership
      interest and which engages in the sale of integrated customer care
      solutions and billing services to energy marketers in the United States
      and Canada;

 .  AGL Peaking Services, Inc., which owns a 50% interest in Etowah LNG Company
   LLC ("Etowah"), a joint venture with Southern Natural Gas Company. Etowah was
   formed for the purpose of constructing, owning, and operating a liquefied
   natural gas peaking facility.

Regulation of the Utility Business

The GPSC and the TRA regulate the utility business with  respect to rates,
maintenance of accounting records, and various other matters. Generally, the
same accounting  policies  and  practices utilized by non-utility companies are
utilized by the utility for financial reporting under generally accepted
accounting principles. However, sometimes the GPSC and the TRA order an
accounting treatment different from that used by non-regulated companies to
determine the rates  charged to the utility's customers. (See Note 4. Regulatory
Assets and Liabilities.)

Consolidation Policy

AGL Resources utilizes two different accounting methods to report its
investments in its subsidiaries and other companies: consolidation and the
equity method.

Consolidation. AGL Resources utilizes the consolidation method of accounting
when it owns a majority of the voting stock of the subsidiary or if it can
otherwise exercise control over the entity. This means that the accounts of AGL
Resources are combined with the subsidiaries' accounts. Additionally,
intercompany balances and transactions are eliminated when the accounts are
consolidated. AGL Resources' consolidated financial statements include the
accounts of the following  subsidiaries:

   .  AGLC and its subsidiary, Chattanooga;
   .  AGLE;
   .  AGL Investments, Inc. and its subsidiaries.

                                                                              43

Notes to Consolidated Financial Statements

Utilipro's assets, liabilities, and earnings are included in the consolidated
financial statements. The outside investors' ownership interest is recorded as
minority interest.  As of September 30, 1999 and 1998, the minority interest was
immaterial.

The Equity Method. The equity method is utilized to account for and report
corporate joint ventures where AGL Resources holds a 20% to 50% voting interest,
unless control can be exercised over the entity. Under the equity method, AGL
Resources' ownership interest in the entity is reported as an investment within
its Consolidated Balance Sheets. Additionally, AGL Resources' percentage
ownership in the joint venture's earnings or losses is reported in its
Statements of Consolidated Income.

AGL Resources utilizes the equity method to account for and report its
investments in the following:

  .  Sonat Power Marketing L.P. ("Sonat Power Marketing");
  .  Sonat Marketing Company L.P. ("Sonat Marketing");
  .  Etowah LNG Company LLC; and
  .  SouthStar.

During the fourth quarter of fiscal 1999, AGL Resources sold its interests in
Sonat Power Marketing and Sonat Marketing.

Utility Revenues

The utility's revenues are recorded in AGL Resources'  Statements of
Consolidated Income when services are provided to customers. Those revenues
include estimated amounts for gas delivered, but not yet billed. Revenues from
the utility business are based on rates approved by the GPSC and the TRA.

On July 1, 1998, AGLC began billing customers under a new straight fixed
variable ("SFV") rate structure that recovers non-gas costs evenly throughout
the year consistent with the way the costs are incurred. In order to detect
potential marketer default at the earliest possible time and to protect
customers from marketer default, AGLC bills marketers on the seventh business
day of each month for all fixed charges during the current month. Such bills are
due ten days later. (See Note 2. Impact of Deregulation.)

The GPSC authorized a weather normalization adjustment rider ("WNAR") for AGLC,
which was in effect during fiscal 1997, and the first nine months of fiscal
1998. In addition, the TRA has authorized a WNAR for Chattanooga. These riders
are designed to offset the impact of unusually cold or warm weather on customer
billings and operating margin. On June 30, 1998, the WNAR for AGLC was
discontinued since the rate design mandated by the Georgia Natural Gas
Competition and Deregulation Act ("Deregulation Act") eliminated the effect of
weather-related volumetric variances on non-gas cost revenue collections. The
WNAR for Chattanooga remains in effect.

Cost of Sales

Historically, the utility has incurred costs for the natural gas that it
purchased and resold to customers. In fiscal 1998, AGLC and Chattanooga charged
their customers for the natural gas consumed using Purchased Gas Adjustment
("PGA") mechanisms set by the GPSC and the TRA. Under the PGA, AGLC and
Chattanooga deferred (included as a current asset or liability in the
Consolidated Balance Sheets and excluded from the Statements of Consolidated
Income) the difference between the utility's actual cost of gas and what it
collected from customers in a given period.  Then, the utility either billed or
refunded its customers the deferred amount.

Effective October 6, 1998, AGLC discontinued the use of its PGA mechanism in
accordance with Georgia's deregulation plan. In January 1999, AGLC signed a
joint stipulation agreement with the GPSC limiting the profit and risk of loss
for the period from October 6, 1998 to September 30, 1999 related to the sale of
gas to $1.0 million and $3.3 million, respectively. Under the joint stipulation
agreement, AGLC deferred the difference between the utility's actual cost of gas
(including carrying charges on underground storage) and what it collected from
customers during the deregulation transition period.

For the year ended September 30, 1999, AGLC received revenues in excess of
purchased gas costs of $38.9 million. In accordance with the January 26, 1999
joint stipulation agreement entered into with the GPSC, profits of $1.0 million
have been recognized and a current liability of $37.9 million has been recorded
under the caption "Gas Cost Credits" in the Consolidated Balance Sheets. AGLC
expects to refund this liability net of any other uses approved by the GPSC
during fiscal 2000. (See Note 2. Impact of Deregulation.)

Notes to Consolidated Financial Statements

Risk Management

Consistent with fiscal 1998, AGLC's Gas Supply Plan for fiscal 1999 included
limited gas supply hedging activities.  During the first quarter of fiscal 1999,
AGLC entered into certain hedge agreements that continued until the end of
February 1999.  As part of the joint stipulation agreement, option agreements
prior to the date of the joint stipulation agreement have been included in gas
costs which were recovered from AGLC's customers during fiscal 1999.

Income Taxes

The reporting of AGL Resources' assets and liabilities for financial accounting
purposes differs from the reporting for income tax purposes. The tax effects of
the differences in those items are reported as deferred income tax assets or
liabilities in AGL Resources' Consolidated Balance Sheets. The utility's
investment tax credits have been deferred and are being amortized as credits to
income over the estimated lives of the related properties in accordance with
regulatory treatment. (See Note 3. Income Taxes.)

Evaluation of Assets for Impairment

Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
("SFAS 121") requires AGL Resources to review long-lived assets and certain
intangibles for impairment when events or changes in circumstances indicate that
the carrying amount of an asset may not be recoverable. Any impairment losses
are reported in the period in which the recognition criteria are first applied
based on the fair value of the asset. In accordance with SFAS 121, AGL Resources
has evaluated its long-lived assets for financial impairment. AGL Resources
recorded charges totaling $13.9 million during the fourth quarter of fiscal
1998. Those charges, recorded in total other operating expenses, included:

 .  A $10.8 million expense related to the impairment of certain assets no longer
   useful primarily due to changes in its information technology systems
   strategy; and

 .  A $3.1 million expense due to a decision by management not to seek recovery
   for certain deferred expenses.

As of September 30, 1999, AGL Resources believes that no asset impairments
exist.

Utility Plant and Depreciation

Utility plant is the term utilized to describe the utility's business property
and equipment which is in use, being held for future use, and under
construction. Utility plant is reported at its original cost, which includes:

 .  Material and labor;
 .  Contractor costs;
 .  Construction overhead costs (where applicable); and
 .  An allowance for funds used during construction
   (described later in this note).

Retired or otherwise-disposed-of utility plant is charged to accumulated
depreciation.

Depreciation Expense. The depreciation for the utility is computed by applying
composite, straight-line rates (approved by the GPSC and TRA) to the average
investment in classes of depreciable utility property. The composite straight-
line depreciation rates for depreciable utility property excluding
transportation equipment during fiscal years 1999, 1998, and 1997 were 3.1%,
3.0%, and 3.0%, respectively. Transportation equipment is depreciated on a
straight-line basis over a period of five to ten years.

Allowance for Funds Used During Construction ("AFUDC"). Construction projects
are financed with borrowed funds and equity funds. The GPSC allows AGLC to
record the cost of those funds as part of the cost of construction projects on
AGL Resources' Consolidated Balance Sheets and as AFUDC in the Statements of
Consolidated Income. AFUDC is calculated based upon a rate authorized by the
GPSC. Beginning July 1, 1998, the GPSC authorized a rate of 9.11% for AFUDC.
For the nine months ended June 30, 1998, and for fiscal 1997, the authorized
AFUDC rate was 9.32%.

Non-Utility Plant and Depreciation

Non-utility plant is the term utilized to describe AGL Resources' non-utility's
business property that is in use, being held for future use, and under
construction. AGL Resources reports its non-utility plant at its original cost.
Gains or losses from retired or otherwise-disposed-of non-utility plant are
recognized for the difference between cost and accumulated depreciation.  Non-
utility depreciation is computed on a straight-line basis over the lives of
various classes of property.

                                                                              45

Notes to Consolidated Financial Statements

Statement of Cash Flows

For the reporting of cash flows, cash equivalents are defined as highly liquid
investments that mature in three months or less.

Non-cash investing and financing transactions include the following:

 .  The issuance of common stock for ResourcesDirect, a stock purchase and
   dividend reinvestment plan; the Retirement Savings Plus Plan; the Long-Term
   Stock Incentive Plan; the Nonqualified Savings Plan; and the Non-Employee
   Directors Equity Compensation Plan of $10.2 million in fiscal 1999, $12.0
   million in fiscal 1998, and $12.5 million in fiscal 1997; and

 .  The issuance of 200,000 shares of AGL Resources common stock in the amount of
   $3.9 million for the acquisition of propane operations in June 1997.

During fiscal 1998, AGL Resources recorded non-cash charges of $13.9 million
related to the impairment of certain long-lived assets.

Earnings per Common Share

Earnings per common share for all periods have been computed under the
provisions of Statement of Financial Accounting Standards No. 128, "Earnings Per
Share," which was adopted October 1, 1997, and calls for the restatement of all
periods presented on a comparable basis. Basic earnings per common share
excludes dilution and 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 price was less than the average market price of the common shares for
the respective periods.

During the fiscal years ended September 30, 1999, 1998, and 1997, AGL Resources
issued 677,411, 739,380 and 753,866 shares of common stock, respectively, under
ResourcesDirect, a direct stock purchase and dividend reinvestment plan; the
Retirement Savings Plus Plan; the Long-Term Stock Incentive Plan; the
Nonqualified Savings Plan; and the Non-Employee Directors Equity Compensation
Plan. Those issuances increased common stockholders' equity by $11.7 million,
$12.9 million and $13.8 million for fiscal 1999, 1998, and 1997, respectively.

During fiscal 1999, 868,688 shares of AGL Resources common stock were purchased
in connection with the termination of the Leveraged Employee Stock Ownership
Plan ("LESOP"). The shares were purchased at $18.50 per share, and are held by
AGL Resources in treasury.

The following weighted average common share and common share equivalent amounts
were used for the calculations of basic and diluted earnings per common share.
The common share equivalents relate to stock options under stock compensation
plans.

</TABLE>

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 for its services. At September 30, 1999, AGLC billed
15 certificated marketers in Georgia for services, that in turn bill the 1.4
million end-use customers. As a result of deregulation, AGLC now bills
certificated marketers for intrastate delivery and other services and no longer
has recourse to the end-use customer for collection. (See Note 10. Commitments
and Contingencies.)

As of September 30, 1999, 25.8% of AGL Resources' total gas receivables were due
from 7 of the 15 certificated and active marketers and 58.7% were due from end-
use customers in Georgia who migrated to certificated marketers late in the
fiscal year or who were randomly assigned. In fiscal 2000, only gas receivables
attributable to Chattanooga will be due from end-use customers. As a result, at
September 30, 2000, a significantly higher percentage of AGL Resources' total
gas receivables will be due from Georgia certificated marketers.

Notes to Consolidated Financial Statements

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 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.

Use of Accounting Estimates

Estimates and assumptions are made when preparing financial statements under
generally accepted accounting principles. Those estimates and assumptions affect
various matters:

 .  Reported amounts of assets and liabilities in AGL Resources' Consolidated
   Balance Sheets at the dates of the financial statements;

 .  Disclosure of contingent assets and liabilities at the dates of the financial
   statements; and

 .  Reported amounts of revenues and expenses in AGL Resources' Statements of
   Consolidated Income during the reporting 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 estimates.

Inventory

In Georgia's new competitive environment, certificated marketers, including
AGLC's marketing affiliate, SouthStar, began selling natural gas to firm end-use
customers at market-based prices in November 1998. Part of the unbundling
process that provides for this competitive environment is the assignment to
certificated marketers certain pipeline services that AGLC has under contract.
AGLC has assigned the majority of its pipeline storage services that it has
under contract to the certificated marketers along with a corresponding amount
of inventory.

AGLC changed its inventory costing method for its gas inventories from first-in,
first-out to weighted-average effective October 1, 1998. In management's
opinion, the weighted-average inventory costing method provides for a better
matching of costs and revenue from the sale of gas. Because AGLC recovered all
of its gas costs through a PGA mechanism until October 6, 1998, there is no
cumulative effect resulting from the change in the inventory costing method. Gas
inventories are sold to marketers at the weighted-average cost.

Chattanooga's gas inventories are stated at cost using the last-in, first-out
method.  Materials and supplies inventories are stated at lower of average cost
or market.

Recently Issued Accounting Pronouncements

During fiscal 1999, AGL Resources adopted the Financial Accounting Standards
Board ("FASB") Statement No. 130, "Reporting Comprehensive Income", Statement
No. 131, "Disclosure about Segments of an Enterprise and Related Information",
and Statement No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits". None of these statements had a material effect on the
consolidated financial statements.

In June 1998, the FASB 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 in
fiscal 2001. The impact of SFAS 133 on AGL Resources' consolidated financial
statements is under review and is currently unknown.

Notes to Consolidated Financial Statements

Note 2. Impact of Deregulation

The regulated rate structure under which AGLC has 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. Additionally, the regulated rate structure assumed that such
costs would be eliminated at the time the switch was made. This structure
therefore reduces the per customer revenue collected by AGLC in the month
following the transfer of a customer to a certificated marketer. However, AGLC's
experience has been that a significant portion of the costs associated with
customer service activities, including billing, bill inquiry, payment processing
and collection services, cannot be eliminated immediately after a customer
switch is made as is assumed by the regulated rate structure. Instead, a period
of up to several months exists during which AGLC continues to incur these
expenses. As a result, a disparity now exists between the speed at which AGLC is
assumed for regulated rate design purposes to be reducing costs and the speed at
which AGLC actually is able to reduce costs. During fiscal 1999, this disparity
was exacerbated by the rapid pace at which customers switched to certificated
marketers.

The accelerated pace of customer migration to certificated marketers also has
required AGLC to incur additional customer service expenses, not originally
provided for in regulated rates, in order to maintain an adequate level of
customer service during the transition to competition. In particular, beginning
in October 1998, and continuing each month thereafter, the number of customer
calls handled by the call centers significantly exceeded the number of customer
calls handled by the call centers during the same months of the preceding year.
The call center volumes increased 26% in fiscal 1999 as compared to fiscal 1998.
As a result, AGLC increased its staffing of customer service representatives and
increased other call center related expenses rather than reducing them, despite
the fact that at September 30, 1999, AGLC had approximately 82% fewer gas sales
service customers than at September 30, 1998.

Customers are switched to certificated marketers on the first day of the month
following the receipt of a switch request. At September 30, 1999, approximately
18% of the customers had not been switched to certificated marketers. Such
customers were switched on October 1, 1999, with the exception of approximately
15,000 customers who are expected to switch during the first quarter of fiscal
2000. Therefore, as of October 1, 1999, almost all of AGLC's remaining customers
began receiving service from certificated marketers. At September 30, 1999,
AGLC's annual delivery service revenues for fiscal 1999 associated with
providing ancillary services and certain transition revenues were reduced as
compared to prior year by approximately $38.6 million; however, associated costs
were not reduced by the same amount, resulting in an adverse effect on net
income. Transition revenues decreased $15.8 million due to customer migration to
certificated marketers. The remaining decrease of $22.8 million was primarily
due to the timing of the implementation of the new SFV rate structure for AGLC
delivery service that became effective during the fourth quarter of fiscal 1998.
The impact of the revenue and cost imbalance related to the transition to
competition is expected to continue into fiscal 2000.

AGLC is pursuing solutions to this revenue and cost imbalance aggressively,
including reducing or eliminating costs as quickly as possible, consistent with
prudent business practices, and increasing employee productivity at customer
call centers. The Deregulation Act authorizes an electing distribution company,
like AGLC, to recover prudently incurred costs that are "stranded" as a result
of the transition to competition. 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 to be "stranded." The Order was approved
on October 19, 1999.  The Order allows AGLC to defer these costs if incurred
from October 1, 1999 to September 30, 2000, and recovery is necessary in order
for AGLC to earn the 11% return on common 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.

On January 26, 1999, AGLC entered into a joint stipulation agreement with the
GPSC to resolve certain gas sales service issues. Among other requirements in
the stipulation, AGLC implemented a rate structure for gas sales, beginning with
February 1999 bills, that was more closely aligned with the traditional
customers' actual gas usage and includes a demand charge for fixed costs
associated with gas sales that is entirely volumetric. The revised rates for gas
sales service is intended to ensure AGLC's recovery of its purchased gas costs
incurred from October 6, 1998 to September 30, 1999 without creating any
significant income or loss. The joint stipulation agreement provided for a true-
up of any profit or loss outside of a specified range during fiscal 1999.

<PAGE>

Notes to Consolidated Financial Statements

The allowed maximum profit for the period October 6, 1998 to September 30, 1999
was $1.0 million and the maximum risk of loss was $3.3 million. For the period
October 6, 1998 to September 30, 1999, AGLC received revenues in excess of costs
of $38.9 million. Through September 30, 1999, AGLC recognized profits of $1.0
million and has recorded a liability of $37.9 million under the caption "Gas
Cost Credits" on the Consolidated Balance Sheets. AGLC expects to refund these
over-recoveries net of any other uses authorized by the GPSC during fiscal 2000.

Note 3. Income Taxes

Income Tax Expense

AGL Resources has two categories of income taxes in its Statements of
Consolidated Income: current and deferred.  AGL Resources' current income tax
expense consists of federal and state income tax less applicable tax credits.
AGL Resources' deferred income tax expense generally is equal to the changes in
the deferred income tax liability during the year.

Investment Tax Credits

AGL Resources has deferred investment tax credits associated with its utility as
a regulatory liability in its Consolidated Balance Sheets. Those investment tax
credits are being amortized as credits to income in accordance with regulatory
treatment over the estimated life of the related properties. AGL Resources
reduces income tax expense in its Statements of Consolidated Income for the
investment tax credits and other tax credits associated with its non-utility
subsidiaries. (See Note 4. Regulatory Assets and Liabilities.)

Deferred Income Tax Assets and Liabilities

AGL Resources reports some of its assets and liabilities differently for
financial accounting purposes than it does for income tax purposes. The tax
effects of the differences in those items are reported as deferred income tax
assets or liabilities in AGL Resources' Consolidated Balance Sheets.  The assets
and liabilities are measured utilizing income tax rates that are currently in
effect. Because of the regulated nature of the utility's business, a regulatory
tax liability has  been recorded in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes."  The regulatory tax
liability is being amortized over approximately 30 years. (See Note 4.
Regulatory Assets and Liabilities.)

Components of income tax expense shown in the Statements of Consolidated Income
are as follows:

Note 4. Regulatory Assets and Liabilities

The GPSC and the TRA regulate the utility business. AGL Resources generally uses
the same accounting policies and practices used by nonregulated companies for
financial  reporting under generally accepted accounting principles. However,
sometimes the GPSC and the TRA order an accounting treatment different from that
used by nonregulated companies to determine the rates the utility charges its
customers. When that happens, certain utility expenses  and income must be
deferred and reported in the  Consolidated Balance Sheets as regulatory assets
and liabilities. These deferred items are then recognized in the Statements of
Consolidated Income through amortization when the items are included in the
rates charged the utility's customers.

AGL Resources has recorded assets and liabilities in its 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.

Georgia has enacted legislation, the Deregulation Act, which allows deregulation
of natural gas sales and the separation of some ancillary services of local
natural gas distribution companies. However, the rates local gas distribution
companies charge to transport natural gas through their intrastate pipeline
system will continue to be regulated by the GPSC.  Therefore, the continued
application of SFAS 71 is appropriate for regulatory assets and liabilities
related to AGLC and delivery services.

Note 5. Employee Benefit Plans and Stock-Based Compensation Plans

Substantially all of AGL Resources' employees are eligible to participate in its
employee benefit plans.

Pension Benefits

AGL Resources sponsors a defined benefit retirement plan for its employees. A
defined benefit plan specifies the amount of benefits an eligible plan
participant eventually will receive using information about the participant. We
generally calculate the benefits under that plan based on age, years of service,
and pay. Our employees do not contribute to this plan. We fund the plan by
contributing annually the amount required by applicable regulations and as
recommended by our actuary. We calculate the amount of funding using an
actuarial method called the projected unit credit cost method. The plan's assets
consist primarily of marketable securities, corporate obligations, U.S.
government obligations, insurance contracts, mutual funds, and cash equivalents.

AGL Resources has an excess benefit plan that is unfunded and provides
supplemental benefits to some officers after retirement. In September 1994, we
established a voluntary early retirement plan for some AGL Resources officers
that is unfunded and provides supplemental pension benefits to participants who
elected early retirement. The annual expense and accumulated benefits of such
plans are not significant.

The following tables present details about AGL Resources' pension plans at
September 30:

Notes to Consolidated Financial Statements

Employee Savings Plan Benefits

AGL Resources also sponsors the Retirement Savings Plus Plan, a defined
contribution benefit plan. In a defined contribution benefit plan, the benefits
a participant ultimately receives come from regular contributions to a
participant account. Under the Retirement Savings Plus Plan, AGL Resources made
matching contributions to participant accounts in the following amounts:

 .  $3.5 million in fiscal 1999;
 .  $3.5 million in fiscal 1998; and
 .  $3.3 million in fiscal 1997.

AGL Resources' Nonqualified Savings Plan, an unfunded, nonqualified plan similar
to the defined contribution savings plan described above, was established on
July 1, 1995. The Nonqualified Savings Plan provides an opportunity for eligible
employees to contribute for retirement savings. AGL Resources contributions to
the Nonqualified Savings Plan during fiscal 1999, 1998, and 1997 were not
significant.

Employee Stock Ownership Benefits

In January 1988, AGL Resources purchased 2.0 million shares of common stock at
$11.75 per share with the proceeds of a loan secured by the common stock. AGL
Resources did not guarantee the repayment of the loan. The loan was repaid from
regular cash dividends on AGL Resources common stock paid to the Leveraged
Employee Stock Ownership Plan ("LESOP") and from contributions to the LESOP, as
approved by the Board of Directors. Repayment of the loan was completed on
December 31, 1997. Contributions to the LESOP were as follows:

 .  $0 for fiscal 1999;
 .  $0.2 million for fiscal 1998; and
 .  $0.9 million for fiscal 1997.

AGL Resources terminated its LESOP in fiscal 1999 and distributed the value of
participants' LESOP account balances as of June 15, 1999. At the election of the
participants, the value of each account was distributed in one of three forms:

 . Direct rollover into the Retirement Savings Plus Plan ("401(k) Plan") or into
  another tax-qualified retirement plan;

 . Lump sum payment in the form of a certificate for shares of AGL Resources
  common stock; or

 . Lump sum cash payment based on the market value of AGL Resources common stock
  at the close of business on June 14, 1999, which was $18.50 per share.

During the year ended September 30, 1999, 868,688 LESOP shares were repurchased
in cash by AGL Resources from the LESOP trustee in a non-brokered transaction at
a purchase price of $18.50 per share, and are held by AGL Resources as treasury
shares. AGL Resources reissues these treasury shares for the Long-Term Incentive
Plan ("LTIP"), Long-Term Stock Incentive Plan ("LTSIP"), Dividend Reinvestment
Plan ("DRIP"), and the Non-Employee Directors Equity Compensation Plan
("Directors Plan"). An additional 236,625 shares were transferred to
participants' accounts under the Retirement Savings Plus Plan from the
respective participants' accounts in the LESOP.

Postretirement Benefits

AGL Resources sponsors defined benefit postretirement health care and life
insurance plans, which cover nearly all employees if they reach retirement age
while working for AGL Resources. The benefits under these plans are generally
calculated based on age and years of service.

Some retirees contribute a portion of health care plan costs.  Retirees do not
contribute toward the cost of the life insurance plan.

Effective October 1, 1993, AGL Resources adopted Statement of Financial
Accounting Standards No. 106, "Employer's Accounting for Postretirement Benefits
Other Than Pensions," which requires accrual of postretirement benefits other
than pensions during the years an employee provides service.  In 1993, the GPSC
approved a five-year phase-in that deferred a portion of other postretirement
benefits expense for future recovery, with an amortization period of 19 years. A
regulatory asset has been recorded for that amount. In 1993, the TRA approved
the recovery of other postretirement benefits expense that is funded through an
external trust.

For purposes of measuring the accumulated postretirement benefit obligation, the

 .  9.5% in 1999, decreasing 0.5% per year to 6.0% in the year 2006, decreasing
   0.3% to 5.7% in 2007, and decreasing 0.5% to 5.2% in 2008.

The assumed health care inflation rate for post-Medicare eligibility is as
follows:

 .  8.0% in 1999, decreasing 0.5% per year to 5.5% in the year 2004, decreasing
   0.25% to 5.25% in 2005, and decreasing 0.25% to 5.0% in 2006.

Net periodic postretirement benefits costs were recovered from utility customers
as follows:

 .  $10.9 million in fiscal 1999;
 .  $11.3 million in fiscal 1998; and
 .  $11.3 million in fiscal 1997.

The difference between AGL Resources' total net postretirement benefits costs
and the associated costs recovered from the utility's customers of $0.8 million
in fiscal 1999 and $0.7 million in fiscal 1998 represents the amortization of
the regulatory asset. The corresponding difference of $0.3 million in fiscal
1997 was deferred for future recovery through amortization and recognized as a
regulatory asset in the financial statements consistent with regulatory
decisions. (See Note 4. Regulatory Assets and Liabilities.)

Notes to Consolidated Financial Statements

Stock-Based Compensation Plans

AGL Resources maintains the LTSIP that provides for grants of restricted stock
awards, incentive and nonqualified stock options, and stock appreciation rights
to key employees. The LTSIP currently authorizes the issuance of up to 3.2
million shares of AGL Resources common stock. AGL Resources also maintains the
LTIP that became effective January 1, 1999. The LTIP provides for grants of
restricted stock, performance units and incentive and nonqualified stock options
to key employees.  The LTIP currently authorizes the issuance of up to 2.8
million shares of AGL Resources common stock. No LTIP awards were made in fiscal
1999. In addition, AGL Resources sponsors the Directors Plan in which all non-
employee directors participate. The Directors Plan provides for the issuance of
restricted stock and nonqualified stock options. The Directors Plan currently
authorizes the issuance of up to 200,000 shares of AGL Resources common stock.
Key employees and non-employee directors realize value from option grants only
to the extent that the fair market value of AGL Resources common stock on the
date of exercise of the option exceeds the fair market value of the common stock
on the date of grant.


LTSIP Stock Awards

Stock awards generally are subject to some vesting restrictions.  AGL Resources
recognizes compensation expense for those stock awards over the related vesting
periods. AGL Resources awarded  shares of stock to key employees in the
following amounts:

 .  20,714 shares in fiscal 1999;
 .  41,424 shares in fiscal 1998; and
 .  31,863 shares in fiscal 1997.

At the date of the award, the weighted average fair value of the shares was as
follows:

 .  $20.610 in fiscal 1999;
 .  $19.890 in fiscal 1998; and
 .  $20.125 in fiscal 1997.

The compensation costs that have been charged against income, for the restricted
stock and other stock-based awards, were immaterial in fiscal 1999, 1998, and
1997.


LTSIP Incentive and Nonqualified Stock Options

Incentive and nonqualified stock options are granted at the fair market value on
the date of grant. The vesting of incentive options is subject to a statutory
limitation of $100,000 per year under Section 422A of the Internal Revenue Code.
Otherwise, nonqualified options generally become fully exercisable six months
after the date of grant and generally expire 10 years after that date.

A summary of activity related to grants of incentive and nonqualified stock
options follows:

AGL Resources applies Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees," and related interpretations in accounting for
its stock option plans. Accordingly, no compensation expense has been recognized
in connection with our LTSIP option grants. If AGL Resources had determined
compensation expense for the issuance of options based on the fair value method
described in SFAS No. 123, "Accounting for Stock-Based Compensation," net income
and earnings per common share would have been reduced to the pro forma amounts
presented  below:


For the years ended Sept. 30,              1999       1998       1997
- ----------------------------------------------------------------------

Net income - as reported (millions)       $74.4      $80.6      $76.6

Net income - pro forma (millions)         $72.8      $79.4      $75.6

Basic earnings per common
   share - as reported                    $1.30      $1.41      $1.37

Basic earnings per common

Diluted earnings per common
   share - pro forma                      $1.27      $1.39      $1.35


In accordance with the fair value method of determining  compensation expense,
the weighted average grant date fair value per share of options granted was as
follows:

 .  $2.68 in fiscal 1999;
 .  $2.55 in fiscal 1998; and
 .  $2.93 in fiscal 1997.

AGL Resources used the Black-Scholes pricing model to estimate the fair value of
each option granted with the following weighted average assumptions:

Non-Employee Directors Equity Compensation Plan ("Directors Plan")

Under the Directors Plan, each non-employee director receives an annual grant
of:

 .  A stock award equal to the fair market value of the $16,000 annual retainer,
   which is payable to each non-employee director; and

 .  A nonqualified stock option to purchase the same number of shares of common
   stock as the annual stock award.

Nonqualified stock options are granted at the fair market value on the date of
grant. Options generally expire 10 years after the date of grant. Non-employee
directors were granted options to purchase an aggregate of the following:

 .  7,437 shares in fiscal 1999;
 .  7,980 shares in fiscal 1998; and
 .  7,960 shares in fiscal 1997.

Notes to Consolidated Financial Statements

Note 6. Common Stock

Shareholder Rights Plan

On March 6, 1996, AGL Resources' Board of Directors adopted a Shareholder Rights
Plan. The plan contains provisions to protect AGL Resources' shareholders in the
event of unsolicited offers to acquire AGL Resources or other takeover bids and
practices that could impair the ability of the Board of Directors to represent
shareholders' interests  fully. As required by the Shareholder Rights Plan, the
Board of Directors declared a dividend of one preferred share purchase right (a
"Right") for each outstanding share of AGL  Resources common stock, with
distribution made to shareholders of record on March 22, 1996.

The Rights, which will expire March 6, 2006, initially will be represented by
and traded together with, AGL Resources common stock. The Rights are not
currently exercisable and do not become exercisable unless some triggering
events occur. One of the triggering events is the acquisition of 10% or more of
AGL Resources common stock by a person or group of affiliated or associated
persons. Unless previously redeemed, upon the occurrence of one of the specified
triggering events, each Right will entitle its holder to purchase one one-
hundredth of a share of Class A Junior Participating Preferred Stock at a
purchase price of $60. Each preferred share will have 100 votes, voting together
with the common stock. Because of the nature of the preferred shares' dividend,
liquidation and voting rights, one one-hundredth of a share of preferred stock
is intended to have the value, rights, and preferences of one share of common
stock. As of September 30, 1999, 1.0 million shares of Class A Junior
Participating Preferred Stock were reserved for issuance under that plan.


Other

AGL Resources issued the following shares of common stock under ResourcesDirect,
a stock purchase and dividend reinvestment plan; the Retirement Savings Plus
Plan; the Long-Term Stock Incentive Plan; the Nonqualified Savings Plan; and the
Non-Employee Directors Equity Compensation Plan.

 .  677,411 shares of common stock in fiscal 1999;
 .  739,380 shares of common stock in fiscal 1998; and
 .  753,866 shares of common stock in fiscal 1997.


As of September 30, 1999, 9,380,655 shares of common stock were reserved for
issuance pursuant to ResourcesDirect, the Retirement Savings Plus Plan, the
Long-Term Stock Incentive Plan, the Nonqualified Savings Plan, and the Non-
Employee Directors Equity Compensation Plan and the Long-Term Incentive Plan.


Note 7. Preferred Stock

Subsidiary Obligated Mandatorily Redeemable Preferred Securities ("Capital
Securities")

In June 1997, AGL Resources established AGL Capital Trust I (the "Trust"), a
Delaware business trust, and AGL Resources owns all the common voting
securities. The Trust issued and sold $75.0 million principal amount of 8.17%
Capital Securities (liquidation amount $1,000 per Capital Security) to certain
initial investors. The Trust used the proceeds to purchase 8.17% Junior
Subordinated Deferrable Interest Debentures, which are due June 1, 2037, from
AGL Resources.

The Capital Securities are subject to mandatory redemption at the time of the
repayment of the Junior Subordinated Debentures on June 1, 2037, or the optional
prepayment by AGL Resources after May 31, 2007. AGL Resources fully and
unconditionally guarantees all the Trust's obligations for the Capital
Securities.


Other Preferred Securities

As of September 30, 1999, AGL Resources had 10.0 million shares of authorized,
and unissued, Class A Junior Participating Preferred Stock, no par value; and
10.0 million shares of authorized, and unissued, preferred stock, no par value.
As of September 30, 1999, AGLC had 10.0 million shares of authorized, and
unissued, preferred stock, no par value.

Notes to Consolidated Financial Statements

Note 8. Long-Term Debt

Long-term debt matures more than one year from the date of issuance. Medium-term
notes Series A, Series B, and Series C were issued under an Indenture dated
December 1, 1989. The notes are unsecured and rank on parity with all other
unsecured indebtedness. Net proceeds from the issuance of medium-term notes were
used to fund capital expenditures, repay short-term debt, and for other
corporate purposes. The annual maturities of long-term debt for the five-year
period ending September 30, 2004 are as follows:

 .  $50.0 million in fiscal 2000;
 .  $20.0 million in fiscal 2001;
 .  $45.0 million in fiscal 2002;
 .  $48.0 million in fiscal 2003; and
 .  $30.0 million in fiscal 2004.

The outstanding long-term debt as of September 30, net of current maturities, is
as follows:

Note 9. Short-Term Debt

Short-term debt matures within one year from the date of issuance. Lines of
credit with various banks provide for direct borrowings and are subject to
annual renewal. The current lines of credit vary throughout the year from $180
million to $260 million. Certain of the lines are on a commitment-fee basis. As
of September 30, 1999, $260.0 million was available on lines of credit. Weighted
average interest rates on short-term debt outstanding were 5.6%, 5.8%, and 5.9%
as of September 30, 1999, 1998, and 1997, respectively.


Note 10. Commitments and Contingencies

Agreements for Firm Pipeline and Storage Capacity

In connection with its utility business, AGL Resources has agreements for firm
pipeline and storage capacity that expire at various dates through 2014. The
aggregate amount of required payments for AGLC under such agreements total
approximately $1.1 billion, with annual payments of $203 million in fiscal 2000,
$185 million in fiscal 2001, $163 million in fiscal 2002, $63 million in fiscal
2003, and $52 million in fiscal 2004. Total payments of fixed charges under all
agreements were $203 million in fiscal 1999, $220 million in fiscal 1998, and
$215 million in fiscal 1997.

As a result of the Deregulation Act, AGLC's rights to capacity under the
agreements are assigned to certificated marketers as they acquire firm
customers. For approximately 70% of such charges, certificated marketers are
responsible for payment of the charges associated with these assignments. AGLC
makes payments for the remaining 30% and then bills to and collects from
certificated marketers all such payments made. In case of certificated marketer
default, AGLC remains responsible for all payments as long as it is the holder
of these contracts. (See Note 17. Subsequent Events.)

The aggregate amount of required payments for Chattanooga under such agreements
totals approximately $45 million, with annual payments of $12 million in fiscal
2000, $12 million in fiscal 2001, $12 million in fiscal 2002, $4 million in
fiscal 2003, and $1 million in fiscal 2004. Total payments of fixed charges
under all agreements were $13 million in fiscal 1999, 1998, and 1997.


AGLC Gas Supply Contracts

In connection with its utility business, AGLC through AGLE had 24 long-term gas
supply contracts representing 240,000 Dekatherms per day ("Dt/d") of natural gas
for delivery to AGLC's customers. These agreements had various terms that
expired at various dates through 2014. Beginning in April 1999, AGLE began
exiting these agreements, typically by exercising the regulatory "out" clauses
in many of these contracts. As a result of this effort, 17 contracts were
terminated at no cost to AGLE, AGLC, certificated marketers, or consumers.


                                                                              57
<PAGE>

Notes to Consolidated Financial Statements

AGLE expects to terminate the remaining contracts on November 1, 1999. AGLC was
permitted by the GPSC to utilize gas cost credits to buydown and buyout the
remaining $2.4 million of reservation charges. The aggregate amount for the
buydown and buyout which appears to be probable is approximately $2.0 million.
AGLE no longer has supply contracts for natural gas supply to AGLC.


Chattanooga Gas Supply Contracts

AGLE also purchases natural gas for Chattanooga. As of September 30, 1999, AGLE
held four gas supply contracts representing 35,000 Dt/d of longer-term gas
supply through the year 2003. The remainder of Chattanooga's gas supply is met
by AGLE purchasing gas on the spot market.


FERC Order 636:
Transition Costs Settlement Agreements

The utility purchases natural gas transportation and storage services from
interstate pipeline companies, and the Federal Energy Regulatory Commission
("FERC") regulates those services and the rates the interstate pipeline
companies charge for them. During the past decade, the FERC has transformed
dramatically the natural gas industry through a series of generic orders
promoting competition in the industry. As part of that transformation, the
interstate pipelines that serve the utility have been required to:

 .  Unbundle, or separate, their transportation and gas supply services; and

 .  Provide a separate transportation service on a nondiscriminatory basis for
   the gas that is supplied by numerous gas producers or other third parties.

The FERC is considering further revisions to its rules, including the
following:

 .  Its policies governing secondary market transactions; and

 .  Revisions that would 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 whether those changes will be adopted or how they
potentially might affect it.

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 September 30, 1999, approximately $105.8 million of those costs
had been incurred and were being recovered primarily from the utility customers'
rates charged for gas sales. Going forward, AGLC's remaining costs will be
recovered from certificated marketers.

The largest portion of the transition costs the utility must pay consists of gas
supply realignment costs that Southern Natural Gas Company ("Southern") and
Tennessee Gas Pipeline Company ("Tennessee") bill the utility. The utility and
other parties have entered restructuring settlements with Southern and Tennessee
that resolve all transition cost issues for those pipelines.

Under the Southern settlement, the utility's share of Southern's transition
costs is about $89.7 million, of which the utility incurred $87.6 million as of
September 30, 1999. Under the Tennessee settlement, the utility's share of
Tennessee's transition costs is about $14.7 million, all of which had been
incurred by the utility as of September 30, 1999.

Southern filed a general rate case on September 1, 1999. Its proposed rates
would represent a 10% increase (about $15 million per year) under AGLC's
existing contracts in firm interstate pipeline charges. These rates would become
effective March 1, 2000, subject to refund unless the FERC should accept an
offer of settlement between Southern and its customers. Such a settlement is
currently under discussion.


Collective Bargaining Agreements

On September 30, 1999, AGL Resources and its subsidiaries had 2,892 employees.
Of that total, approximately 700 employees are covered under collective
bargaining agreements. Based on current pay levels, it is anticipated that the
majority of bargaining unit employees will not receive any base pay increases
until the year 2000. The collective bargaining agreements expire in September
2000 and 2001. Certain of those agreements will be renegotiated beginning in
January 2000.

Notes to Consolidated Financial Statements

Rental Expense

Total rental expense for property and equipment was as follows:

 .  $8.5 million in fiscal 1999;
 .  $7.7 million in fiscal 1998; and
 .  $6.5 million in fiscal 1997.

Minimum annual rentals under non-cancelable operating leases are as follows:

 .  Fiscal 2000 - $11.7 million;
 .  Fiscal 2001 - $11.6 million;
 .  Fiscal 2002 - $11.8 million;
 .  Fiscal 2003 - $9.3 million;
 .  Fiscal 2004 - $8.7 million; and
 .  Thereafter  - $7.2 million.

On October 14, 1998, AGL Resources entered into an arrangement to sublease
certain corporate office space, the term of which began on December 1, 1998, and
will expire on January 3, 2003. The original lease is an operating lease. Annual
sublease rental receipts are as follows:

 .  Fiscal 2000 - $1.5 million;
 .  Fiscal 2001 - $1.5 million;
 .  Fiscal 2002 - $1.5 million; and
 .  Fiscal 2003 - $0.4 million.


Litigation

AGL Resources is involved in litigation arising in the normal course of
business. Management believes the ultimate resolution of that litigation will
not have a material adverse effect on the consolidated financial statements.
(See Note 12. Environmental Matters.)

Related Party Guarantees

In the normal course of business, AGL Resources Inc., from time to time,
guarantees, or provides collateral for, the obligations of its subsidiaries and
affiliates.

Note 11. Suppliers' Refunds

The utility has received refunds from its interstate natural gas suppliers.
Those refunds are a result of FERC orders that adjust the price of various
pipeline services purchased by the utility from suppliers in prior periods.
Under purchased gas provisions of rate schedules approved by the TRA,
Chattanooga credits the refunds to customers. Under purchased gas provisions of
rate schedules approved by the GPSC, AGLC credited the refunds to customers
until June 30, 1998.  Beginning July 1, 1998, and thereafter, the Deregulation
Act requires AGLC to credit refunds from interstate natural gas suppliers to a
universal service fund. The universal service fund provides a method to fund the
recovery of certificated marketers' uncollectible accounts, and it enables AGLC
to expand its facilities to serve the public interest.


Note 12. 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 twelve 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 used the following process for the estimates:
First, AGLC eliminated the sites where it was believed that no cleanup or
further investigation was likely to be necessary. Second, AGLC estimated its
likely future cost of investigation and cleanup at each of the remaining sites.
Third, for some sites, AGLC estimated its likely "share" of the costs. AGLC
developed its estimate based on any agreements for cost sharing it has, the
legal principles for sharing costs, its evaluation of other entities' ability to
pay, and other similar factors.

Using the above process, 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

                                                                              59
<PAGE>

Notes to Consolidated Financial Statements

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. Consequently, AGLC has recorded
the lower end of the range, or $102.4 million, as a liability and a
corresponding regulatory asset as of September 30, 1999. AGLC does not believe
that any single number within the range constitutes a "better" estimate because
its actual future investigation and cleanup costs will be affected by a number
of contingencies that cannot be quantified at this time. During fiscal 1999, the
asset increased $78.7 million and was reduced by amortization of $6.1 million
resulting in an asset of $150.2 million.

As of September 30, 1998, AGLC had recorded a liability of $47.0 million. During
fiscal 1999, the liability increased $78.7 million and payments of $23.3 million
were made. The net increase in the liability was $55.4 million resulting in a
liability of $102.4 million as of September 30, 1999. The net increase in the
liability was based on revised estimates of future costs, which resulted in a
corresponding increase in the unrecovered environmental response cost asset.

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. During fiscal 1999, AGLC
recovered $6.1 million through its environmental response recovery rider.

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 fiscal 1999 and 1998.

Note 13. Fair Value of Financial Instruments

In the following table, the carrying amounts and fair values of financial
instruments included in AGL Resources' Consolidated Balance Sheets as of
September 30, 1999, and 1998 are shown.

1999

Long-term debt including current portion          $ 660.0      $ 640.8

Capital Securities                                   74.3         70.0

1998

Long-term debt including current portion          $ 660.0      $ 714.6

Capital Securities                                   74.3         81.5

The estimated fair values are determined based on the following:

 .  Long-term debt - interest rates that are currently available for issuance of
   debt with similar terms and remaining maturities; and

 .  Capital Securities - quoted market price and dividend rates for preferred
   stock with similar terms.

Considerable judgment is required to develop the fair value  estimates;
therefore, the values are not necessarily indicative of the amounts that could
be realized in a current market exchange. The fair value estimates are based on
information available to management as of September 30, 1999. Management is not
aware of any subsequent factors that would affect significantly the estimated
fair value amounts.

Note 16. 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 in fiscal 1999, 1998, or 1997. Identifiable assets are those assets used
in each segment's operations.

Note 17. Subsequent Events

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. A portion of the proceeds from AGL Resources recent sales of
its joint venture interests in Sonat Marketing and Sonat Power Marketing will be
used to fund the shares repurchase. 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.

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
September 30, 1999, AGL Resources' total gas receivables included approximately
$6.8 million attributable to Peachtree. As of September 30, 1999, AGLC held
financial surety bonds totaling $11 million as security for Peachtree's
obligations.  As of the date of Peachtree's bankruptcy filing, Peachtree owed
AGLC approximately $14.2 million and AGLC continued to hold the $11 million of
surety bonds. The amount owed to AGLC does not include amounts owed by Peachtree
to interstate pipelines for assigned capacity. Based upon information filed by
Peachtree in its bankruptcy proceeding, as of the date of Peachtree's filing,
Peachtree owed interstate pipelines approximately $1.8 million for assigned
capacity. Peachtree obtains a portion of its customer care solutions from
Utilipro. As of September 30, 1999, included in AGL Resources' other receivables
was $1.7 million due to Utilipro from Peachtree. As of the date of Peachtree's
bankruptcy filing, Peachtree owed Utilipro $2.1 million.

On November 17, 1999, Peachtree entered into an agreement to sell its customers
and storage gas inventories to another certificated marketer. This sale is
expected to close prior to December 31, 1999. Management does not believe that
Peachtree's bankruptcy will have a material adverse effect on AGL Resources'
consolidated financial statements.

Notes to Consolidated Financial Statements

Note 18. Quarterly Financial Data (Unaudited)

During the fourth quarter of fiscal 1999, AGL Resources sold its interest in
Sonat Power Marketing and Sonat Marketing for a total after-tax gain of $22.3
million.

During the quarter ended September 30, 1998, AGL Resources recorded non-cash,
nonrecurring charges of $13.9 million associated with the impairment of certain
assets no longer  useful primarily due to changes in our information technology
systems strategy. During the quarter ended September 30, 1998, AGL Resources
reduced its income tax liability for prior years by $2.3 million. (See Note 1.
Significant Accounting Policies.)

Quarterly financial data for fiscal 1999 and 1998 is summarized as follows (See

(a) The wide variance in quarterly earnings results from the highly seasonal
    nature of AGL Resources' primary business. (See Note 2. Impact of
    Deregulation.)

Basic and diluted earnings per common share are calculated based on the weighted
average number of common shares and common share equivalents outstanding during
the quarter. Those totals differ from the basic and diluted earnings per common
share, as shown on the Statements of Consolidated Income, which are based on the
weighted average number of common shares and common share equivalents
outstanding during the entire year.

Independent Auditors' Report

To the Shareholders and Board of Directors
of AGL Resources Inc.:

We have audited the accompanying consolidated balance sheets of AGL Resources
Inc. and subsidiaries as of September 30, 1999 and 1998, and the related
statements of consolidated income, common stockholders' equity, and cash flows
for each of the three years in the period ended September 30, 1999. These
financial statements are the responsibility of AGL Resources' management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of AGL Resources Inc. and subsidiaries
as of September 30, 1999 and 1998, and the results of its operations and its
cash flows for each of the three years in the period ended September 30, 1999,
in conformity with generally accepted accounting principles.

Management's Responsibility for Financial Reporting

The consolidated financial statements and related information  are the
responsibility of management. The financial statements have been prepared in
conformity with generally  accepted accounting principles appropriate in the
circumstances. The financial information contained elsewhere in this Annual
Report is consistent with that in the financial statements.

AGL Resources Inc. maintains a system of internal accounting controls designed
to provide reasonable assurance that assets are safeguarded from loss and that
transactions are executed and recorded in accordance with established
procedures. The concept of reasonable assurance is based on the recognition that
the cost of maintaining a system of internal accounting controls should not
exceed related benefits. The system of internal accounting controls is supported
by written policies and guidelines.

The financial statements have been audited by Deloitte & Touche LLP, independent
auditors. Their audits were made in accordance with generally accepted auditing
standards, as indicated in the Independent Auditors' Report, and included a
review of the system of internal accounting controls and tests of transactions
to the extent they considered necessary to carry out their responsibilities.

The Board of Directors pursues its responsibility for reported financial
information through its Audit Committee. The Audit Committee meets periodically
with management and the independent auditors to assure that they are carrying
out their responsibilities and to discuss internal accounting controls, auditing
and financial reporting matters.
