                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. The consolidated financial statements of EnergySouth, Inc. and its
subsidiaries (collectively the "Company") include the accounts of Mobile Gas
Service Corporation; EnergySouth Services, Inc., formerly MGS Energy Services,
Inc.; MGS Storage Services; MGS Marketing Services, Inc.; an 87.5% owned
partnership, Bay Gas Storage Company, Ltd. ("Bay Gas"); and a 51% owned
partnership, Southern Gas Transmission Company ("SGT"). All significant
intercompany balances and transactions have been eliminated.

Note 2. The accompanying unaudited condensed financial statements have been
prepared in accordance with the instructions to Form 10-Q and do not include all
of the information and footnotes required by generally accepted accounting
principles for complete financial statements. All adjustments, consisting of
normal and recurring accruals, which are, in the opinion of management,
necessary to present fairly the results for the interim periods have been made
and are of a recurring nature. The statements should be read in conjunction with
the summary of accounting policies and notes to financial statements included in
the Annual Report on Form 10-K of the Company for the fiscal year ended
September 30, 1998.

Note 3. Due to the high percentage of customers using gas for heating, the
Company's operations are seasonal in nature. Therefore, the results of
operations for the six month periods ended March 31, 1999 and 1998 are not
indicative of the results to be expected for the full year.

Note 4. Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" was effective for the Company on October 1, 1998. The
Company does not currently have any comprehensive income other than items
included in net income. Therefore, comprehensive income is the same as net
income for all periods reported.

Note 5. Statement of Financial Accounting Standards No, 131, "Disclosure about
Segments of an Enterprise and Related Information" (SFAS 131) is effective for
the Company for the fiscal year ending September 30, 1999. SFAS 131 establishes
standards for reporting operating segments by public business enterprises in
annual financial statements and requires that those enterprises report selected
information about operating segments in interim financial reports issued to
shareholders. SFAS 131 also establishes standards for related disclosures about
products and services, geographic areas, and major customers. Interim
disclosures are not required in the year of adoption; accordingly, the Company
expects to report the required financial and descriptive information about its
operating segments beginning with its annual financial statements for the fiscal
year ending September 30, 1999.

Note 6. Effective October 1, 1998 the Company changed its method of accounting
for unbilled revenues to be consistent with prevailing industry practice. Prior
to October 1, 1998, the Company recorded revenues as meters were read on a
monthly cycle basis and the commodity cost of purchased gas applicable to gas
delivered but not yet billed at month-end was deferred. The accrual method
adopted records revenues based upon estimated consumption through the end of the
month for all customers regardless of the meter reading date. The effect of the
change for the six months and twelve months ended March 31, 1999 was to increase
net income by $490,000 ($0.10 per share, diluted) of which $255,000 ($.05 per
share, diluted) is included in operating income, and $235,000 ($0.05 per share,
diluted), 


                                       7
<PAGE>   8

the cumulative effect of the change, is reported as a separate component of net
income. This change in accounting method has the effect of recognizing income
earlier within the fiscal year but will have a minimal impact on the fiscal year
as a whole.

Note 7. Effective October 1, 1998, the Company adopted Statement of Position
98-5, "Reporting on the Costs of Start-Up Activities" (SOP 98-5) and recorded a
cumulative effect of change in accounting method of $616,000 ($.13 per share,
diluted) as a result of expensing organization and start-up costs previously
capitalized. The effect on operating income as a result of not expensing the
amortization of such costs is not material to the financial statements.

Note 8. Basic earnings per share are computed based on the weighted average
number of common shares outstanding during each period. Diluted earnings per
share are computed based on the weighted average number of common shares and
diluted potential common shares, using the treasury stock method, outstanding
during each period. Average common shares used to compute basic earnings per
share differed from average common shares used to compute diluted earnings per
share by equivalent shares of 52,000 and 67,000 for the three months ended March
31, 1999 and 1998, respectively; 51,000 and 68,000 for the six months ended
March 31, 1999 and 1998, respectively; and 53,000 and 56,000 for the twelve
months ended March 31, 1999 and 1998, respectively. These differences in
equivalent shares are from outstanding stock options.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                 OF FINANCIAL CONDITION AND RESULTS OF OPERATION

THE COMPANY

     The following discussion and analysis encompasses EnergySouth, Inc. and its
direct and indirect subsidiaries (collectively referred to as the "Company").
EnergySouth became the holding company for Mobile Gas Service Corporation
(Mobile Gas) on February 2, 1998, and at that time Mobile Gas became a
wholly-owned subsidiary. The Company, primarily through Mobile Gas, is engaged
principally in the distribution of natural gas to residential, commercial and
industrial customers in Southwest Alabama. Other subsidiaries are engaged in
providing gas pipeline transportation, gas storage, gas marketing and other
energy-related services. The Alabama Public Service Commission (APSC) regulates
the Company's gas distribution and storage operations. Mobile Gas' rate tariffs
for gas distribution allow a pass-through to customers of the cost of gas
supplies, certain taxes, and incremental costs associated with the replacement
of cast iron mains. These costs, therefore, have little impact on the Company's
earnings. Other costs, including a return on investment, are recovered through
rates approved in traditional rate proceedings. Interstate gas storage contracts
do not require APSC approval since the Federal Energy Regulatory Commission
(FERC), which has jurisdiction over such contracts, allows them to have
market-based rates. Market-based rates allow Bay Gas to respond to market
conditions and minimize regulatory involvement in the setting of its rates for
storage services. The FERC issued an order on April 28, 1999 granting authority
to Bay Gas to provide transportation-only services to interstate and intrastate
shippers and approved rates for such service.

         The Company's distribution business is highly seasonal and
temperature-sensitive since residential and small commercial customers use more
gas during colder weather for heating. As a result, the Company's operating
results in any given period historically have reflected, in addition to other
matters, the impact of weather, through either increased or decreased sales
volumes. The Company utilizes a temperature rate adjustment rider to offset the
impact that unusually cold or warm weather has on customer billings and
operating margins by reducing high gas bills in colder than normal weather and
increasing gas revenues in warmer than normal weather. Normal weather for the
Company's service territory is defined as the 30-year average temperature as
determined by the National Weather Service. In the gas utility industry,
degree-days are the benchmark for measuring coldness and represent the number of
degrees that the daily average temperature falls below 65 degrees Fahrenheit.

RESULTS OF OPERATIONS

NET INCOME

         Net income for the three months ended March 31, 1999 and 1998 was
$3,759,000 or $.76 per share and $4,791,000 or $.97 per share, respectively. Net
income for the six months ended March 31, 1999 and 1998 was $6,276,000 or $1.27
per share and $6,779,000 or $1.38 per share, respectively. Net income for the
twelve months ended March 31, 1999 and 1998 was $7,914,000 or $1.61 per share
and $8,005,000 or $1.63 per share, respectively. All references to earnings per
share amounts are computed on a diluted basis. The fiscal 1999 period earnings
include the effect of a change in accounting for unbilled revenues while the
fiscal 1999 six and twelve month periods also include the effect of a change in 


                                       9
<PAGE>   10

accounting for start-up costs. In accordance with prescribed accounting rules,
the amounts presented for the same prior year periods have not been adjusted.
Both accounting changes are discussed in further detail within "New Accounting
Standards" below. The effect of these accounting changes for the three months
ended March 31, 1999 was to decrease net income by $588,000 ($0.12 per share)
while the effect on the fiscal 1999 six and twelve month periods was to decrease
net income by $126,000 ($0.03 per share). Assuming retroactive application of
the accounting changes, earnings per share amounts for three, six and twelve
months ended March 31, 1999 would have been $0.76, $1.35 and $1.64,
respectively, as compared to $0.84, $1.42 and $1.61, respectively, for the
three, six and twelve months ended March 31, 1998.

         The decrease in earnings for the three and six months ended March 31,
1999, assuming retroactive application of the accounting changes, is due
primarily to decreased margin on gas sales revenues resulting from unusually
warm weather, decreased gas storage revenues, increased operations expenses and
increased depreciation expense. The increase in earnings for the twelve months
ended March 31, 1999 is due primarily to increased margin on gas transportation
revenues, decreased maintenance expenses and decreased interest expense.

OPERATING REVENUES

         Gas revenues decreased $5.4 million (19%), $5.8 million (12%) and $5.7
million (8%), respectively, for the three, six and twelve months ended March 31,
1999 as compared to the same prior year periods. Included within gas revenues
for each fiscal 1999 period is the effect of accruing for unbilled gas revenues
at month-end while no such accrual is included within prior year periods since
this new accounting method was adopted in the first quarter of fiscal 1999.
Assuming retroactive application of this accounting change, gas revenues
decreased $2.7 million (11%), $6.7 million (14%) and $6.6 million (9%),
respectively, for the three, six and twelve months ended March 31, 1999
resulting primarily from decreased gas sales volumes of 21%, 26% and 21%,
respectively. Causing these decreases in gas sales volumes, primarily to
temperature-sensitive customers, was weather which was 22%, 37% and 36%,
respectively, warmer than the prior year three, six and twelve month periods and
22%, 27% and 26%, respectively, warmer than normal for the three, six and twelve
month periods. The temperature adjustment rider in rates mitigated the effects
of weather to a large extent; however, margins from customers who are sensitive
to weather were slightly down from the prior year for the three and six month
periods. In addition to the effect on gas revenues of lower gas sales volumes,
the Company passed through to customers lower purchased gas costs on a per unit
basis during the fiscal 1999 periods through the purchased gas adjustment
component of customer rates.

         Gas revenues from large commercial and industrial customers decreased
$762,000, $1,331,000 and $2,032,000, respectively, for the three, six and twelve
months ended March 31, 1999 due in part to factors mentioned previously in
addition to decreased plant utilization and several customers switching to
transportation agreements. Transportation revenues during the three, six and
twelve months ended March 31, 1999 increased $43,000, $363,000 and $1,231,000,
respectively, due primarily to several new customers added to the distribution
system and certain sales customers who switched to transportation agreements.
Revenues from natural gas storage operations decreased $76,000, $148,000 and
$46,000, respectively, for the three, six and twelve months ended March 31, 1999
due primarily to decreased firm storage contracted to customers. 


                                       10

EXPENSES

         Cost of gas decreased $3.9 million (35%), $6.0 million (33%) and $6.5
million (28%), respectively, for the three, six and twelve months ended March
31, 1999 as compared to the same prior year periods. Included within each fiscal
1999 period is an accrual for cost of gas associated with unbilled gas revenues
whereas the prior year periods do not reflect such an accrual. Assuming
retroactive application of the accounting change for unbilled gas revenues, cost
of gas decreased $2.3 million (25%), $6.5 million (35%) and $7.2 million (30%),
respectively, for the three, six and twelve months ended March 31, 1999. The
decrease for all periods is attributed to decreased gas sales volumes and
decreased purchased gas costs on a per unit basis as mentioned previously.

         Operations expense increased $367,000, $493,000 and $190,000,
respectively, for the three, six and twelve months ended March 31, 1999 compared
to the same prior year periods due primarily to increases in the following
areas: payroll and related benefits, reserve for uncollectible accounts, and
selling expenses.

         Maintenance expense decreased $101,000, $137,000 and $309,000,
respectively, for the three, six and twelve months ended March 31, 1999 compared
to the same prior year periods due primarily to decreased maintenance on mains
and services.

         Depreciation expense increased 4% for the second quarter of fiscal 1999
and increased 5% for the six and twelve months ended March 31, 1999 as compared
to the same prior year periods due to growth in depreciable plant-in-service.

         Taxes, other than income taxes, primarily consist of state and local
taxes that are based on gross revenues and fluctuate accordingly.

         Interest expense decreased 8%, 4% and 5%, respectively, for the three,
six and twelve months ended March 31, 1999 as compared to the same prior year
periods due to decreased long-term debt which was due in part to the early
redemption of $2,500,000 of First Mortgage Bonds, 10.25% Series, during the
first quarter of fiscal 1999.

         Allowance for borrowed funds used during construction represents the
capitalization of interest costs to construction work-in-progress. Capitalized
interest costs decreased $55,000 for the twelve months ended March 31, 1999 due
to completion in August 1997 of new facilities to service a large industrial
customer.

         Interest income increased $19,000, decreased $47,000 and increased
$15,000, respectively, for the three, six and twelve months ended March 31, 1999
as compared to the same prior year periods. Interest income of $42,000 related
to an income tax refund was recorded during the fiscal 1998 first quarter,
whereas the fiscal 1999 periods do not include any such miscellaneous interest
income. The fluctuation in interest income for each period is due primarily to
financing of merchandise sales and installations and income from short-term
investments.

         Income tax expense changed primarily in relation to changes in income
before income taxes.

NEW ACCOUNTING STANDARDS

         Effective October 1, 1998 the Company changed its method of accounting
for unbilled revenues to be consistent with prevailing industry practice. Prior
to October 1, 1998, the Company recorded revenues as meters were read on a
monthly cycle basis and the commodity cost of purchased gas applicable to gas
delivered but not yet billed at month-end was deferred. The accrual method
adopted records revenues based upon estimated consumption through the end of the
month for all customers regardless of the meter reading date. This change in
accounting method has the effect of recognizing income earlier within the fiscal
year but will have a minimal impact on the fiscal year as a whole. As of
December 31, 1998, unbilled revenue had increased net income by $1,078,000
($0.22 per share, diluted) of which $843,000 ($0.17 per share, diluted) was
included in operating income and $235,000 ($0.05 per share, diluted), the
cumulative effect of the accounting change, was reported as a separate component
of net income. During the three months ended March 31, 1999, a portion of this
effect reversed so that the six and twelve month periods ended March 31, 1999
reflect an increase in net income of $490,000 ($0.10 per share, diluted) of
which $255,000 ($0.05 per share, diluted) is included in operating income and
$235,000 ($0.05 per share, diluted) is reflected as the cumulative effect of the
accounting change.

         Effective October 1, 1998, the Company adopted Statement of Position
98-5, "Reporting on the Costs of Start-Up Activities" (SOP 98-5) and recorded a
cumulative effect of change in accounting method of $616,000 ($0.13 per share,
diluted) as a result of expensing organization and start-up costs previously
capitalized. The effect on operating income as a result of not expensing the
amortization of such costs is not material to the financial statements.

         Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS 130) was effective for the Company on October 1,
1998. The Company does not currently have any comprehensive income other than
items included in net income. Therefore, comprehensive income is the same as net
income for all periods reported.

         Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information" (SFAS 131) is effective for
the Company for the fiscal year ending September 30, 1999. SFAS 131 establishes
standards for reporting operating segments by public business enterprises in
annual financial statements and requires that those enterprises report selected
information about operating segments on interim financial reports issued to
shareholders. SFAS 131 also establishes standards for related disclosures about
products and services, geographic areas, and major customers. Interim
disclosures are not required in the year of adoption, accordingly, the Company
expects to report the required financial and descriptive information about its
operating segments beginning with its annual financial statements for the fiscal
year ending September 30, 1999.

FINANCIAL CONDITION AND LIQUIDITY

         The Company generally relies on cash generated from operations and on a
temporary basis, short-term borrowings, to meet working capital requirements and
to finance normal capital expenditures. The Company issues debt and equity for
longer term financing as needed.


                                       12
<PAGE>   13

         Operating activities provided cash of $12,255,000 and $8,510,000,
respectively, for the six months ended March 31,1999 and 1998. The increase in
cash flow from operating activities is attributed primarily to the change in
operating assets and liabilities, which reflects the timing of cash receipts and
payments on receivables and payables.

         Financing activities used cash of $18,701,000 and $14,568,000
respectively, for the six months ended March 31, 1999 and 1998. The increase in
cash used by financing activities primarily reflects the early redemption of
$2,500,000 of First Mortgage Bonds, 10.25% Series during the fiscal 1999 first
quarter in addition to increased payments on short-term borrowings.

         Cash used in investing activities increased $472,000 during the six
months ended March 31, 1999 primarily as a result of the Company's regular
construction program. The Company's capital needs for construction of
distribution and storage facilities, purchase of equipment and other general
improvements for the remainder of fiscal 1999 is estimated to be $9,375,000.
Funds for the Company's cash needs are expected to come from cash provided by
operations and borrowings under the Company's revolving credit agreement.
Management believes it has adequate financial flexibility to meet its expected
cash needs in the foreseeable future.

YEAR 2000

         The Company is working to resolve the potential impact of the Year 2000
on the ability of computerized information systems to accurately process
information that may be date sensitive. Programs that recognize a date using
"00" as the year 1900 rather than 2000 could result in errors or system failures
that could ultimately cause the Company to interrupt service or become unable to
process transactions and could thereby require the Company to cease operations
pending resolution of the problem. Such an eventuality would materially
adversely affect the Company's business, financial condition and results of
operations. Accordingly, management is devoting significant attention to
identifying Year 2000 issues and testing its systems for Year 2000 compliance.

         The identification, assessment, remediation and testing of the
Company's computer systems have been substantially completed. As a result, the
Company has made changes to its computer application programs and tested them
accordingly. Additional testing will be completed during 1999 to ensure that no
subsequent changes have affected the Year 2000 modifications. The state of Year
2000 readiness of hardware and software already evaluated will be monitored
during the coming year to maintain this readiness and to determine that there
have been no subsequent exclusions or disclaimers by manufacturers resulting in
a loss of Year 2000 readiness. Mission critical processes have been identified
and contingency plans are being developed at this time and are scheduled for
completion by the end of June 1999 in an effort to ensure the uninterrupted
continuation of customer service. An inventory and assessment of the Company's
embedded systems has been completed. The two systems for which failure of
embedded systems would be critical are responsible for monitoring and
controlling 1) the distribution of gas through the Company's pipeline system and
2) the underground storage facility. These systems are scheduled for replacement
by June 30, 1999.

         In addition to the remediation and testing efforts of the Company's
internal systems, the Company is contacting each of its significant vendors to
obtain a commitment that they 


                                       13
<PAGE>   14

are or will be Year 2000 compliant. If such assurances are not forthcoming, or
if management believes for any reason that any of its significant vendors will
not be Year 2000 compliant when required, management plans to either contract
with other vendors that would be able to provide similar services at similar
costs or have plans in place so operations will not be materially affected.

         During March 1999, the Company's Year 2000 project was subjected to a
third party Readiness Review for completeness. The Company has responded to the
recommendations made by the third party review which includes a limited amount
of on-going testing of third party software, continued assessment and inquiry of
significant vendors and finalizing contingency plans for mission critical
processes. A steering committee of the Company's executive management has
reviewed and will continue to review the Year 2000 project progress on a regular
basis.

         As of March 31, 1999, the Company has incurred approximately $164,000
of remediation costs related to Year 2000 which has been expensed and expects to
incur an additional $23,000 to complete the remediation costs. The Company has
been utilizing working capital to fund its Year 2000 compliance program and
anticipates that it will continue to do so. The Company's internal costs with
respect to the Year 2000 project have not been separately identified, but
Management believes that they are immaterial.

         The Company's goal is that Year 2000 issues will be addressed on
schedule and in a manner that will prevent such issues from having a material
effect on the Company's business, financial condition and result of operations.
While the Company has and will be pursuing Year 2000 compliance, there can be no
assurance that the Company and its vendors will be successful in identifying and
addressing all material Year 2000 issues.

                         MOBILE GAS SERVICE CORPORATION
                            TRANSPORTATION AGREEMENT


         THIS AGREEMENT is made and entered into as of this 18th day of
February, 1999 by and between MOBILE GAS SERVICE CORPORATION, an Alabama
corporation, with a mailing address of P. O. Box 2248, Mobile, Alabama 36652,
herein called "Mobile Gas," and ALABAMA POWER COMPANY, an Alabama corporation,
with a mailing address of 600 North 18th Street, Birmingham, Alabama, 35291,
herein called "Customer."

         Whereas, Customer desires to use natural gas for the operation of
Customer's proposed electric and steam generation facilities to be located in
Theodore, Alabama (the "Plant"); and

         Whereas, Mobile Gas operates a system for the distribution of natural
gas from natural gas transmission pipelines and processing plants and Customer
intends that it will purchase natural gas from third parties ("Customer's
Suppliers") who will deliver such gas to Mobile Gas for redelivery to the Plant.

         NOW THEREFORE, in consideration of the mutual covenants herein
contained, the parties hereto agree as follows:

                       ARTICLE I - TRANSPORTATION SERVICE

1.1 Mobile Gas shall transport volumes of natural gas up to the "Contract Demand
Volume" of Customer's gas, as defined in Exhibit A which is attached hereto and
made part of this Agreement. Customer will pay Mobile Gas for all natural gas
transported by Mobile Gas to the Plant and agrees to accept and pay for service
subject to the terms and conditions hereof:

1.2 The RATE for such transportation service and the minimum billings
hereunder are as specified in Exhibit A which is attached hereto and
made part of this Agreement. The rate is a special negotiated rate.

1.3 Customer may request that the Contract Demand Volume be increased by
delivering a written request to Mobile Gas for such increase. Mobile Gas may
approve or decline such request in its discretion (such request being deemed to
be declined if Mobile Gas does not approve the request within thirty (30) days
after the date of receipt thereof). In the event Mobile Gas approves such a
request, it may specify an effective date for the requested increase in the
Contract Demand Volume, such date to be not later than 24 months after the
approval date.




<PAGE>   2



1.4 Except as otherwise specified in this section, Mobile Gas shall be the sole
transporter of natural gas to the Plant during the term of this Agreement for
the Contract Demand Volume. If during the term of this Agreement Mobile Gas, due
to default by Mobile Gas or force majeure affecting Mobile Gas is unable to
deliver adequate volumes, Customer may obtain transportation of gas volumes from
other sources for the duration of such default or force majeure.


                         ARTICLE II - TERM OF AGREEMENT

2.1 The term of this Agreement shall be ***, beginning on the Commencement Date,
as herein defined, and shall be automatically extended for a period of *** from
each expiration date of such term or any automatic extension thereof unless
either party shall notify the other in writing not less than ninety (90) days
prior to the expiration date, or the expiration of any two year extension of
such expiration date, of its intention to terminate this Agreement.

2.2 The "Commencement Date" shall be the first day of the month following the
earlier of (i) the date Customer first takes redelivery of natural gas from
Mobile Gas at the Point of Redelivery, or (ii) six (6) months from the date of
this Agreement.

2.3 Notwithstanding the provisions of Section 2.1, the provisions of this
Agreement that by their sense and context are applicable to the parties' rights
and obligations under this Agreement prior to the Commencement Date, shall be
effective as of the effective date hereof. The provisions of this Agreement,
that by their sense and context survive the termination or expiration of this
Agreement, shall survive the same.

2.4 This Agreement may only be terminated prior to the expiration of the initial
term or a renewal term hereof, if any, as the case may be:

                  (a) by Mobile Gas, (i) in accordance with Section 5.3, or (ii)
                  after occurrence of any other material breach by Customer in
                  the performance of its obligations hereunder and the
                  continuance of such breach thirty (30) days after written
                  notice by Mobile Gas to Customer of such breach and demand by
                  Mobile Gas that Customer cure same.

                  (b) by Customer after occurrence of any material breach by
                  Mobile Gas in the performance of its obligations hereunder and
                  the continuance of such breach thirty (30) days after written
                  notice by Customer to Mobile Gas of such breach and demand by
                  Customer that Mobile Gas cure same. In the event of
                  termination by either party under this Section 2.4 Customer
                  shall not owe any minimum bill payments as provided for in
                  Exhibit A beyond the date of termination.

                  (c) by Customer if Mobile Gas fails to deliver
                  nominated gas at the Point of Redelivery for a period
                  of forty-five (45) consecutive days for any reason,
                  including the occurrence of force majeure.

                              ARTICLE III - QUALITY

3.1 The volumes of natural gas delivered hereunder shall be measured at an
equivalent pressure base of 14.73 pounds per square inch absolute (psia) and an
assumed atmospheric pressure of 14.7 psia, and at a temperature base of 60
degrees Fahrenheit. The volume of natural gas determined hereunder shall be
adjusted to give effect to Boyle's Law in accordance with standard procedure.

3.2 The quality of the gas delivered by Customer's Suppliers to Mobile Gas shall
be pipeline quality, and:

                  (a) Shall be dehydrated and shall in no event have a water
                  content in excess of seven (7) pounds of water per million
                  (1,000,000) cubic feet of gas measured at a pressure base of
                  14.73 psi and at a temperature base of 60 degrees Fahrenheit,
                  as determined by dew point or other moisture measuring
                  equipment in general use in the industry.

                  (b) Shall not contain more than one (1) grain of hydrogen
                  sulfide per one hundred (100) cubic feet as determined by
                  quantitative methods in general use in the industry.

                  (c) Shall not contain more than twenty (20) grains of total
                  sulphur, including hydrogen sulfide, per one hundred (100)
                  cubic feet as determined by quantitative methods in general
                  use in the industry.

                  (d)      Shall not contain in excess of:

                           (i)    Three percent (3.0%) by volume carbon dioxide.
                           (ii)   Two tenths percent (0.2%) by volume oxygen

                  (e) Shall be commercially free from dust, gum, gum-forming
                  constituents or other liquid or solid matter which might
                  become separate from the gas in the course of transportation
                  through pipelines.

                  (f) Shall be commercially free of water and other
                  objectionable liquids at the temperature and pressure at which
                  the gas is delivered. (g) Shall contain no less than 800 Btu
                  per cubic foot nor more than 1200 Btu per cubic feet at
                  standard temperature and pressure.


                 ARTICLE IV - POINTS OF DELIVERY AND REDELIVERY

4.1 The Points of Delivery by Customer's Suppliers to Mobile Gas shall be as
specified in Exhibit B. From time to time during the term of this Agreement,

                                        3

<PAGE>   4



Customer may change the Primary Point(s) of Delivery hereunder by giving at
least thirty (30) days advance written notice of such change (the "Primary Point
Change"). Mobile Gas shall accept the Primary Point Change as long as sufficient
capacity is available in its Bellingrath Pipeline System, including but not
limited to the pipeline, meter station, and interconnects, to transport the
requested volume from the newly designated Primary Point(s) of Delivery to
Customer's Plant. If sufficient capacity is not available, Mobile Gas shall give
written notification to Customer within fifteen (15) days of receipt of
Customers notice of Primary Point Change of its non-acceptance of the Primary
Point Change.

4.2 The Secondary Point(s) of Delivery by Customer's Suppliers to Mobile Gas
shall be as specified in Exhibit B. Transportation service from Secondary Points
of Delivery shall be on an interruptible basis. Customer shall have no bumping
rights at Secondary Points of Delivery. Mobile Gas shall receive nominated gas
at one or more Secondary Points, as long as sufficient capacity is available in
its Bellingrath Pipeline System, including but not limited to the pipeline,
meter station, and interconnects, to transport the requested volume from the
designated Secondary Point(s) of Delivery to the Plant.

4.3 Customer's Suppliers shall make delivery to the Points of Delivery at a
minimum pressure of 650 pounds per square inch gauge to enable Mobile Gas to
redeliver gas to Customer. Mobile Gas shall not be obligated to redeliver gas at
the Point of Redelivery unless adequate pressures are available at the Points of
Delivery.

4.4 The Point of Redelivery of natural gas hereunder to Customer shall be the
Customer's weld connection downstream of the Mobile Gas Metering Facilities, as
such term is defined below. Maintenance by Mobile Gas of gas pressure of a
minimum of 450 and maximum of 500 pounds per square inch gauge at the Point of
Redelivery shall constitute redelivery of gas for purpose of this Agreement.
Customer shall not be obligated to accept gas at the Point of Redelivery unless
the gas is redelivered at a minimum of 450 pounds per square inch gauge.

4.5 The gas shall be redelivered by Mobile Gas to Customer in like good order
and condition and at quality in accordance with specifications as set forth in
Article III of this Agreement.

4.6 Customer shall be responsible for construction of its pipeline from the
Point of Redelivery to its Plant. Mobile Gas shall at its expense construct such
facilities as may be necessary to enable it to receive gas at the Point(s) of
Delivery stated on Exhibit B and to redeliver gas to Customer at the Point of
Redelivery at the Contract Demand Volume on the Commencement Date. Mobile Gas
shall construct, own, and operate a metering station and necessary monitoring,
and recording equipment to provide accurate measurement and custody transfer of
the gas from Mobile Gas to Customer (the "Metering Facilities.") The Metering
Facilities shall be constructed and operated in accordance with industry
standards. The Metering Facilities shall be located either on the Plant site or
at a mutually acceptable location outside the Plant, at the discretion of Mobile
Gas. If the Metering Facilities are located on the Plant site, Customer shall
provide, within thirty (30) days of this Agreement, Mobile Gas such easement or
easements, in form reasonably acceptable to Mobile Gas, for the Metering
Facilities covering approximately 100 feet by 100 feet of Customer's property,
and for construction of pipelines, including above and below ground facilities

                                        4

<PAGE>   5



to the Point of Redelivery as shall cross property owned or leased by Customer,
as well as for maintenance of the Metering Facilities on Customer's premises.



                               ARTICLE V - BILLING

5.1 On or before the seventh (7th) working day of each calendar month Mobile Gas
shall render to Customer a statement of the amount of gas transported hereunder
by Mobile Gas to Customer during the preceding calendar month (and with respect
to the first such statement, for the portion of a month, if any, between the
date first gas is made available and the Commencement Date), and shall also
render a bill for all gas so transported. On or before the twenty-first (21st)
day of each calendar month, Customer shall make payment to the address stated in
Article X.

5.2 In the event that Customer disputes any amount shown on a statement issued
by Mobile Gas to Customer, Customer shall pay the undisputed amount, which shall
in no event be less than the minimum bill, and notify Mobile Gas of the disputed
amount and the reasons for the dispute at the time payment is due. Mobile Gas
shall not suspend further delivery as a result of Customer's failure to pay the
disputed amount. Mobile Gas and Customer shall endeavor to amicably resolve the
disputed amount prior to institution of arbitration. The parties are not
obligated to pursue amicable resolution for more than sixty (60) days, then the
matter shall be submitted to arbitration. If it is finally determined that
Customer has underpaid the amount actually due, Customer shall remit any amount
due, with interest equal to 2% in excess of the "prime rate" reported in the
Wall Street Journal or any successor thereto, within ten (10) days of the
earlier of the next monthly invoice or within thirty (30) days of dispute
resolution. If it is finally determined that Customer has overpaid the amount
actually due, Mobile Gas shall remit any refund, with interest equal to 2% in
excess of the "prime rate" reported in the Wall Street Journal or any successor
thereto, within ten (10) days of the earlier of the next monthly invoice or
within thirty (30) days after Customer's receipt of an adjusted billing
statement from Mobile Gas.

5.3 Should Customer fail to pay any amount due, and Customer has not notified
Mobile Gas of a disputed amount pursuant to Section 5.2 above (except for any
minimum billings as specified in Exhibit A falling due during any period of
force majeure invoked by Mobile Gas pursuant to Section 6.1) when the same is
due, Mobile Gas shall give notice and interest shall accrue on all unpaid
amounts from the date due until paid at a rate of interest equal to 2% in excess
of the "prime rate" reported in the Wall Street Journal or any successor
thereto. Should such failure to pay continue for ten (10) days, Mobile Gas may
suspend deliveries of gas hereunder, and the exercise of such right shall be in
addition to any and all remedies available to Mobile Gas. Should such failure to
pay continue for ninety (90) days after written notice is given by Mobile Gas to
Customer of such failure to pay, Mobile Gas may terminate this Agreement, and
the exercise of such right shall be in addition to any and all remedies
available to Mobile Gas. Such termination shall not relieve Customer of its
payment obligations hereunder.

                           ARTICLE VI - FORCE MAJEURE

6.1 In the event Mobile Gas is rendered unable, wholly or in part, by reason of
force majeure to carry out its obligations under this Agreement, it is agreed
that Mobile Gas shall give notice and reasonably full particulars of such force
majeure, in writing by either mail, hand delivery, or facsimile, to Customer
within a reasonable time after the occurrence of the cause relied on, and the
obligations of Mobile Gas, so far as they are affected by such force majeure,
shall be suspended during the continuance of any inability so caused, but for no
longer period, and such cause shall, so far as possible, be remedied with all
reasonable dispatch.

6.2 In the event the Customer is rendered unable, wholly or in part, by reason
of force majeure to carry out its obligations under this Agreement (other than
the obligation to make payment of amounts due according to Article V, which
obligations shall not be affected by events of force majeure), it is agreed that
Customer shall give notice and reasonably full particulars of such force
majeure, in writing by either mail, hand delivery, or facsimile, to Mobile Gas
within a reasonable time after the occurrence of the cause relied on, and the
obligations of Customer, so far as they are affected by such force majeure,
shall be suspended during the continuance of any inability so caused, but for no
longer period, and such cause shall, so far as possible, be remedied with all
reasonable dispatch.

6.3 The term, "force majeure," as employed herein shall mean acts of God;
strikes, lockouts, or other industrial disturbances; conditions arising from a
change in governmental laws, orders, rules or regulations; acts of public enemy;
wars; blockades; insurrections; riots; epidemics; landslides; lightning;
earthquakes; fires; storms; floods; washouts; arrests and restraints of
governments and people; civil disturbances; explosions; breakage or accident to
machinery or lines of pipe; the necessity for making repairs, tests or

either Mobile Gas or Customer is required to obtain servitudes, rights-of-way,
grants, permits or licenses to enable such party to fulfill its obligations
under this-Agreement; such party is unable to acquire, at reasonable costs, and
after the exercise of reasonable diligence, such servitudes, rights-of-way,
grants, permits or licenses, and (b) those instances where either Mobile Gas or
Customer's suppliers or transporters or Customer is required to furnish
materials and supplies for the purpose of constructing or maintaining facilities
or is required to secure permits or permissions from any governmental agency to
enable such party to fulfill its obligations under this Agreement and such party

above requirement that any force majeure shall be remedied with all reasonable
dispatch shall not require the settlement of strikes or lockouts by acceding to
the demands of the opposing party when such course is inadvisable in the
discretion of the party having the difficulty.




                           ARTICLE VII - LAW GOVERNING

7.1 This Agreement shall be governed by and construed in accordance with the

                           ARTICLE VIII - ARBITRATION

9.2 Mobile Gas and Customer understand that maintaining gas balance between
receipts and deliveries is important to the success of both Customer's and
Mobile Gas' operations hereunder. Both parties agree to use their best efforts
to exchange information necessary to maintain gas balances. Customer agrees to
use all reasonable efforts to balance its deliveries to the Point(s) of Delivery
with its receipts at the Point(s) of Redelivery. If Customer fails to do so,
Mobile Gas may, in addition to its imbalance remedies set forth in 9.3, take
such action as may be necessary to maintain the integrity of its system.

9.3 The parties shall use all reasonable efforts to avoid imposition of
imbalance charges, penalties, or fees by any supplier or transporter. If, during
any month, Customer or Mobile Gas receives an invoice from a supplier or
transporter which includes imbalance charges, the parties shall use their best
efforts to promptly determine the validity as well as the cause of such
imbalance charges. If the parties determine that the imbalance charges were
incurred as a result of Customer's actions or inactions (which shall include,
but shall not be limited to, Customer's failure to accept quantities of gas at
the Point(s) of Redelivery equal to the nominated gas), then Customer shall pay
for such imbalance charges or reimburse Mobile Gas for such imbalance charges
paid by Mobile Gas to the transporter or supplier. If the parties determine that
the imbalance charges were incurred as a result of Mobile Gas's actions or
inactions, then Mobile Gas shall pay for such imbalance charges, or reimburse
Customer for such imbalance charges paid by Customer to the transporter or
supplier.




                               ARTICLE X - NOTICES

permitted to be given under any provision of this Agreement, unless expressly
provided otherwise, such shall be in writing, signed by or on behalf of the
person giving the same, and shall be deemed to have been given and received upon

                          ARTICLE XI - ENTIRE AGREEMENT

11.1 This instrument embodies the entire Agreement and understanding between the
parties hereto. There are no Agreements, understandings, conditions, warranties,
or representatives, oral or written, express or implied, with reference to the
subject matter hereof that are not merged herein or superseded hereby.



                        ARTICLE XII - SPECIAL PROVISIONS

         The following Special Provisions for TRANSPORTATION are made a part
hereof:

                                        9

<PAGE>   10

12.1 A "day" when used in this Agreement shall mean a twenty-four (24) hour
period ending at 9:00 A.M. Mobile, Alabama Time.


12.2 (a) The accuracy of Mobile Gas' measuring equipment shall be verified at
reasonable intervals and, if required, Customer may have its representative
present. Mobile Gas shall not be required to verify the accuracy of such
metering equipment more frequently than once in any six-(6) month period. Mobile
Gas or Mobile Gas' representatives shall give Customer at least one (1) day
prior notice of any routine tests of the time of all tests of meters.


         (b) In the event Customer shall notify Mobile Gas that it desires a
special test of any measuring equipment, the parties shall cooperate to secure a
prompt verification of the accuracy of such equipment. The expense of any
special test, if called for, shall be borne by Customer if the measuring
equipment tested is found to be in error not more than two percent (2%). If,
upon test, Mobile Gas' measuring equipment is found to be in error by not more
then two percent (2%), previous recordings of such equipment shall be considered
accurate in computing deliveries in gas, but such equipment shall be adjusted at
once to record accurately. If, upon test, Mobile Gas' measuring equipment shall
be found to be inaccurate by an amount exceeding two percent (2%) at a recording
corresponding to an average hourly rate of flow for the period since the last
preceding test, then any previous calculations based on recordings of such
equipment shall be corrected to zero error for any period that is known
definitely, but in case the period is not known or agreed upon, such correction
shall be for a period equal to one-half the time elapsed since the date of the
last test.

         (c) In the event a Mobile Gas meter is out of service or registering
inaccurately, the volume of gas delivered shall be determined:

                           (1) By using the registration of check meter or
                               meters; if installed and agreed accurately
                               registering; or, in the absence of (1);

                           (2) By correcting the error if the percentage of
                               error is ascertainable by calibration, tests, or
                               mathematical calculation; or, in the absence of
                               (1) and (2), then;

                           (3) By estimating the quantity of delivery by
                               deliveries during periods of similar conditions
                               when the meter was registering accurately.

         (d) Mobile Gas and Customer shall each preserve for a period of at
least two (2) years all test data, charts, and other similar records. Each
party, or their designated representatives, shall at all reasonable times have
the right to audit such records and accounts to verify all such costs, fees, and
charges including without limitation the gas balance, receipt and delivery
records.


                                       10

chromatography in general use and acceptance in the industry to measure gas
redelivered hereunder.

         (f) Mobile Gas shall provide a signal or signals, including gas flow,
pressure, and analysis data from its measurement equipment, such that the
Customer may monitor the gas flow.

12.3 (a) Mobile Gas agrees to protect, defend, indemnify, and hold harmless the
Customer, its officers, directors, agents, contractors and/or employees from and
against any claims, demands, losses, damages, suits and expenses, for damages
and/or injury to persons and/or property which may be brought against Customer,
its officers, directors, agents, contractors and/or employees arising out of, or
resulting from, the transportation of natural gas from the Point of Delivery to
the Point of Redelivery pursuant to the terms and conditions expressed herein,
excepting for damages and injuries caused by the sole negligence of Customer.

(b) Customer agrees to protect, defend, indemnify, and hold harmless Mobile Gas,
its officers, directors, agents, contractors, and/or employees from and against
any claims, demands, losses, damages, suits and expenses, for damages and/or
injury to persons and/or property which may be brought against Mobile Gas, its
officers, directors, agents, contractors and/or employees arising out of, or
resulting from, the transportation of natural gas by Customer or its agents or
contractors to the Point of Delivery and from the Point of Redelivery to and
through its Plant and facilities, excepting for damages and injuries caused by
the sole negligence of Mobile Gas.


12.4 (a) Customer warrants for itself, its successors and assigns, that it will
have at the time of delivery of gas for transportation hereunder good title or
valid right to deliver such gas hereunder; that the gas it delivers hereunder
shall be free and clear of all liens, encumbrances, or claims whatsoever; and
that it will indemnify Mobile Gas and save it harmless from all claims, suits,
actions, damages, costs and expenses arising directly or indirectly from or with
respect to the title to gas tendered to Mobile Gas hereunder.

         (b) As between Customer and Mobile Gas, Customer shall be in control
and possession of the gas transported hereunder prior to delivery to Mobile Gas
at the Point of Delivery and after delivery by Mobile Gas to Customer at the
Point of Redelivery, and Mobile Gas shall be in control and possession of the
gas after the receipt of the same at the Point of Delivery and until delivery by
Mobile Gas to Customer at the Point of Redelivery. The risk of loss for all gas
transported hereunder shall be and remain with the party having control and
possession of the gas as herein provided.

12.5 The authorized agents of Mobile Gas shall have, at all reasonable times,
the right of access to the Plant premises for the purpose of examining,
maintaining and inspecting its meters. Mobile Gas representatives shall, at all
reasonable times, comply with Plant rules, including security rules and drug and
alcohol policy, updated copies of which will be furnished to Mobile Gas from
time to time. Mobile Gas shall be responsible for selecting and providing for
its employees suitable hard hats, safety glasses, protective hearing devices and

 12.6 So long as all amounts due and payable to Mobile Gas at such time have
been paid by customer, Mobile Gas agrees to transport additional volumes of gas
to Customer for a period of up to ten (10) days beyond the termination of this
Agreement in order to bring into balance any imbalance that exists at the
termination of this Agreement.

 12.7 This Agreement shall not be assigned or transferred by either party
without prior written consent of the other party, which consent shall not be
unreasonably withheld. Provided, however, that either party may assign this
Agreement to an affiliate with equal or greater creditworthiness which is a

other party. Subject to the foregoing, this Agreement shall be binding upon and
inure to the benefit of the respective legal representatives, successors and
assigns of the parties hereto.

 12.8 In the event one or more of the provisions contained herein shall for any
reasons be held to be invalid, illegal, or unenforceable in any respect, such
invalidity, illegality, or unenforceability shall not affect any other provision
hereof and this Agreement shall be construed as if such invalid, illegal, or
unenforceable provision had never been contained herein.

 12.9 Any changes, modifications or alterations of this Agreement shall not be
effective unless in writing, signed by authorized representatives of the parties
hereto in accord with Section 10.1, and no course of dealing between the parties
shall be construed to alter the terms hereof, except as expressly stated herein.

12.10 Mobile Gas shall at all times, for a period of at least three (3) years
from the month in which transportation service was provided, maintain accurate
books and accounts, in accordance with generally accepted accounting principles,
of its costs, fees and charges of any nature invoiced to Customer hereunder.
Customer or its designated representatives shall at all reasonable times have
the right to audit such books and accounts to verify all such costs, fees, and
charges including without limitation the gas balance, receipt and delivery
records. After three (3) years, all books and accounts are deemed final.

12.11 Customer has designated Southern Company Services, Inc. ("SCS") as its
agent for the purpose of locating, processing and arranging for delivery of gas

and nominations, negotiating and administering this Agreement, and for any other
purpose as may be authorized by Customer. Customer may designate a new agent

X, and authorization of SCS to act as agent for Customer thereupon, shall cease
and the new agent shall have such authority.

labor performed, or materials, equipment, supplies or tools used in the
performance of this contract, and shall promptly notify Customer of any claims

                FIRM AND INTERRUPTIBLE STORAGE SERVICE AGREEMENT


         THIS FIRM AND INTERRUPTIBLE STORAGE SERVICE AGREEMENT (this "Contract")
is made and entered into as of the 1st day of April, 1999, by and between BAY
GAS STORAGE COMPANY, LTD., an Alabama limited partnership ("Bay Gas") which is
the owner and operator of the Storage Facilities defined below, and SOUTHERN
COMPANY SERVICES, INC., as agent of Alabama Power Company, Georgia Power
Company, Gulf Power Company, Mississippi Power Company and Savannah Electric and
Power Company ("Shipper")(collectively referred to herein as Parties and
individually as Party).


                              W I T N E S S E T H:

         WHEREAS, Bay Gas is the operator of certain underground gas storage
facilities located near McIntosh, Alabama (the "Storage Facilities"); and

         WHEREAS, Shipper desires to contract for a portion of the storage
capacity of the Storage Facilities, and desires that Bay Gas receive at the
Point(s) of Receipt herein specified on Exhibit "A" attached hereto, certain
quantities of gas from the pipeline facilities identified therein for the
purpose of injecting and storing such gas for Shipper (or for its account) in
such Storage Facilities, and that Bay Gas deliver such gas into the pipeline
facilities identified on Exhibit "A" attached hereto at the Point(s) of Delivery
therein specified; and

         WHEREAS, Bay Gas desires to perform such services for Shipper, all to
be provided pursuant and subject to the terms and conditions hereof.

         NOW, THEREFORE, for and in consideration of the mutual covenants herein
contained, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Bay Gas and Shipper hereby agree
as follows:



                                    ARTICLE I

                    GAS TO BE RECEIVED, STORED AND DELIVERED

         1.1 Contract Quantities. Subject to the terms and conditions
established herein and in Bay Gas Storage Company's Statement of Conditions
(notwithstanding the provisions of Paragraphs A.1 and A.2 of the Statement of
Conditions), Bay Gas shall provide the following capacities to Shipper, provided
that under no circumstances will Bay Gas be obligated to provide to Shipper
capacities in excess of the maximum quantities set forth below:

     (a)  Firm Withdrawal - a Firm Maximum Daily Withdrawal Quantity ("FMDWQ")
          of *** MMBtu per day;

     (b)  Firm Storage - a Firm Maximum Storage Quantity ("FMSQ") in the Storage
          Facilities equal to *** MMBtu.


                                        2


<PAGE>   4






     (c)  (1) Firm Injection - a Firm Maximum Daily Injection Quantity ("FMDIQ")
          of *** MMBtu per day and;

          (2) Interruptible Injection - an Interruptible Maximum Daily Injection
          Quantity ("IMDIQ") of *** MMBtu per day.

     The  FMDIQ and the IMDIQ will be known collectively as "Injection
          Quantities".


         1.2 Gas Tendered. Shipper shall tender or cause to be tendered to Bay
Gas at the Point(s) of Receipt herein specified on Exhibit "A" attached hereto
any gas which Shipper desires to have injected into storage hereunder. The
obligation of Bay Gas to receive gas shall not exceed: at any Point of Receipt
the lesser of the Injection Quantities for such Point of Receipt or the total
daily volume that Shipper or its designee is able and willing to tender at such
Point of Receipt; or the aggregate Injection Quantities for all Points of
Receipt. Shipper shall also receive or cause to be received gas requested to be
withdrawn from storage at the Point(s) of Delivery herein specified on Exhibit
"A" attached hereto upon tender for delivery by Bay Gas.


         1.3 Gas Received and Delivered. Subject to the operating conditions of
the pipeline(s) delivering or receiving gas for Shipper's account, Bay Gas shall
receive gas for injection from Shipper at the Point(s) of Receipt and deliver
gas to Shipper at the Point(s) of Delivery herein specified on Exhibit "A"
attached hereto as scheduled by Shipper from time to time; provided that Bay Gas
shall not be obligated to receive for injection any quantity of gas if the
injection of the same would cause the quantity of gas stored in the Storage
Facilities for Shipper's account ("Shipper's Gas Storage Inventory") to exceed
the total of Shipper's FMSQ as stated above; nor shall Bay Gas be obligated at
any time to deliver more gas to Shipper than Shipper has in its then-current
Shipper's Gas Storage Inventory.


         1.4 Gas to be Withdrawn on Termination. Shipper must have all of its
gas withdrawn by the end of the term of this Contract. If at any time service
pursuant to this Contract is canceled or terminated prior to the end of the term
specified herein, Shipper shall be required to withdraw its gas within a sixty
(60) day balancing period after the determination by Bay Gas that any
unwithdrawn volumes exist, the maximum number of days allowed for withdrawal to
be determined by dividing: (i) the volume of gas Shipper is required to
withdraw, by (ii) fifty percent (50%) of Shipper's FMDWQ. If Bay Gas is unable
to withdraw any volume requested by Shipper, up to fifty percent (50%) of
Shipper's FMDWQ, the period shall be extended accordingly. If the gas is not
withdrawn within the specified time period, Bay Gas shall take title to such gas
not withdrawn.


                                   ARTICLE II

                             PERFORMANCE OBLIGATION

<PAGE>   5






         2.1 Firm and Interruptible Service. All Firm service rendered under
this Contract shall be provided to Shipper except in the case of force majeure

Interruptible service rendered under this contract shall be fully interruptible.
Bay Gas shall not be obligated to provide capacities in excess of those stated
in Section I of this Contract.

         2.2 Curtailed Capacity. During periods of curtailed capacity Bay Gas
shall, pursuant to Statement of Conditions Section "III.C", provide available
capacity pro rata based on Shipper's Maximum Daily Injection/Withdrawal Quantity
as applicable. Shipper's pro rata share shall be determined by comparing
Shipper's Maximum Daily Injection/Withdrawal Quantity to the lesser of 100% of
Bay Gas' daily capacities, or the total amount of daily capacity contracted to
firm customers of Bay Gas.


                                   ARTICLE III

                                DELIVERY PRESSURE

         Delivery Pressure. Shipper is obligated to deliver gas at the Point(s)
of Receipt identified in Exhibit "A" at a pressure sufficient for Bay Gas to
transport such gas to its storage facility recognizing that the amount of such
pressure required may vary based on the operations of the Bay Gas pipeline;
provided however, Shipper is not required to deliver gas at the Point(s) of
Receipt at pressure(s) greater than stated in Exhibit "A".


                                   ARTICLE IV

                        POINT(S) OF RECEIPT AND DELIVERY

tendered by Shipper to Bay Gas for injection into the Storage Facilities shall
be as specified on Exhibit "A" attached hereto, and the maximum daily quantity

Point of Receipt shall not exceed the maximum stated thereon.


         4.2 Point(s) of Delivery. The Point(s) of Delivery for all gas to be
tendered by Bay Gas to Shipper for delivery pursuant to the terms hereof shall
be as specified on Exhibit "A" attached hereto, and the maximum quantities of

Delivery shall not exceed the maximum stated thereon.


         4.3 Addition / Deletion of Point(s) of Receipt or Delivery. Bay Gas and
Shipper may add or delete Point(s) of Receipt or Delivery from time to time by
mutual agreement evidenced by a signed amendment to Exhibit "A".

to the title to gas tendered to Bay Gas hereunder.


         5.2 No Encumbrance on Stored Gas. Bay Gas covenants that it shall
neither cause nor allow any cloud or encumbrance of any nature to arise by,

free from all liens and adverse claims arising by, through or under Bay Gas, and
that it will indemnify, protect, and save Shipper harmless from all claims,
suits, actions, damages, costs and expenses arising directly or indirectly from
the same.


         5.3 Control and Possession. As between Shipper and Bay Gas: Shipper
shall be in control and possession of the gas prior to delivery to Bay Gas for
injection at the Point(s) of Receipt and after delivery by Bay Gas to Shipper at

any damage or injury caused thereby except for damages and injuries caused by
the sole negligence of Bay Gas; and, Bay Gas shall be in control and possession

                                   ARTICLE VI

                                      TERM

         6.1 Primary Term; Renewal Term. This Contract shall be effective as of
April 1, 1999 and shall continue in full force and effect through *** ("Primary
Term"). At the end of the Primary Term the Parties have the option to extend the

<PAGE>   7






occurs which causes Bay Gas to be unable to provide storage services for a
period of forty-five (45) consecutive days, Shipper may terminate this Contract
upon written notice to Bay Gas.


                                   ARTICLE VII

                             DEFAULT AND TERMINATION

         7.1 If either Party hereto shall fail to perform any of the covenants
or obligations imposed upon it by virtue of this Contract (except where such
failure shall be excused under any of the provisions hereof), then in such event
the other Party may, at its option, terminate this Contract by proceeding as
follows: the Party not in default shall cause a written notice to be served upon
the Party in default, stating specifically the cause for terminating this
Contract and declaring it to be the intention of the Party giving the notice to
terminate the same; whereupon, the in default shall have thirty (30) days after
receipt of the aforesaid notice which to remedy or remove the cause or causes of
default stated in the notice of termination and if, within said period of thirty
(30) days, the Party in default does so remedy and remove such cause or causes,
and fully indemnifies the Party not in breach, then such notice shall be
nullified and this Contract shall continue in full force and effect. In the
event the Party in default does not so remedy and remove the cause or causes of
default, or does not fully indemnify the Party giving the notice for such
Party's actual damages as a result of such breach within said period of thirty
(30) days, then this Contract shall become null and void from and after the
expiration of said period; provided, however, that if such default be remedied
but no indemnification therefor has been made due to a bona fide dispute between
the Parties as to the amount thereof, then this Contract shall not terminate,
but the Party not in default shall have the right to seek recovery of its actual
damages as provided by law. Notwithstanding any provision to the contrary in the
Statement of Conditions or the General Terms and Conditions, any termination for
breach of this Contract shall be carried out strictly in accordance with this
section.

         7.2 Any cancellation of this Contract pursuant to the provisions of
this Article VII shall be without prejudice to the right of the Party not in
default to collect any amounts then due it and without waiver of any other
remedy to which the Party not in default may be entitled.

                                  ARTICLE VIII

                                      RATES

<PAGE>   8






          (b)  Injection and Withdrawal Charges - *** for each MMBtu of gas
               received by Bay Gas for injection into storage hereunder
               ("Injection Charge") and *** for each MMBtu of gas delivered by
               Bay Gas to Shipper hereunder ("Withdrawal Charge") during the
               Primary Term of the Contract. Bay Gas reserves the right to
               exchange gas in lieu of physically injecting or withdrawing
               nominated gas volumes, and gas so exchanged shall be accounted
               and charged for as having been injected or withdrawn as
               nominated.

          (c)  Fuel Charge - A Fuel Charge shall be paid by permitting Bay Gas
               to retain *** of all volumes of gas tendered by Shipper for
               injection at the Storage Facility during the Primary Term of the
               Contract. Upon measurement of volumes tendered by Shipper for a
               given day, *** of the total amount measured shall be applied to
               satisfy Shipper's fuel cost obligation hereunder, and the
               remaining *** shall be applied to computing compliance with the
               applicable FMDIQ and FMSQ, and computing the amount of Shipper's
               Gas Storage Inventory.


         8.2 Renewal Term Rate. During the final year of the Primary Term of the
Contract the Parties shall agree on a rate for the Renewal Term of the Contract.
In the event the Parties can not agree on a rate for the Renewal Term the
Contract shall be terminated at the end of the Primary Term.

         8.3 Suspension of Payments. In the event that Bay Gas is, due to an
event of force majeure as defined in the General Terms and Conditions, unable to
provide storage services, or a portion thereof, under this Contract for a
consecutive twenty (20) day period, then the obligation of Shipper to make
payment hereunder for such unavailable services, or a portion thereof, shall
thereafter be suspended until such service is again made available hereunder. In
the event that Bay Gas is, due to an event of force majeure or curtailment,
unable to provide storage services, or a portion thereof, under this Contract
for a consecutive twenty (20) day period within any calendar year, then any
subsequent curtailment or excused failure, during such calendar year, to provide
storage services hereunder shall result in a pro-rata reduction in the monthly
charges to be paid by Shipper for that month.

         8.4 Rate Changes. The rates herein stated shall be effective for the
term of the Contract and shall not be changed in rate cases before the FERC or
other governing body, or by any other method.


                                   ARTICLE IX

                                      TAXES

         9.1 Shipper agrees to pay to Bay Gas, by way of reimbursement, within
ten (10) days of receipt of an invoice for same, all taxes levied or imposed
upon Bay Gas after the date hereof; and any increases in existing taxes which
may be made effective after the date hereof, with respect to the storage of gas
hereunder. Bay Gas agrees to pass through to Shipper in its monthly billings any
savings resulting from decreases in existing taxes which may be made effective
after the date hereof, with respect to the storage of gas hereunder. In the
event that any

                                        7


<PAGE>   9






additional taxes or increases in taxes are imposed and, should Bay Gas elect not
to challenge the same, then Shipper shall be subrogated to Bay Gas' rights to
challenge the same. In no event shall Shipper be required to pay any tax in a
greater amount than its pro-rata share.


         9.2 The term "taxes" as used in Section 9.1 shall mean all taxes which
are now in existence or which may in the future be levied upon Bay Gas, or its
facilities or the storage of gas hereunder (other than ad valorem, capital
stock, income or excess profit taxes, or general franchise taxes imposed on
corporations on account of their corporate existence or on their right to do
business within the state as a foreign corporation and similar taxes),
including, but not limited to, gross receipts tax, street and alley rental tax,
licenses, fees and any other taxes, charges or fees of any kind levied, assessed
or made by any governmental authority on the act, right or privilege of

         The following are hereby incorporated herein and made a part of this
Contract as if fully set forth herein: (a) the General Terms and Conditions
attached hereto as Exhibit "B"; and the Statement of Conditions for NGPA Section
311(a)(2) Gas Storage Services attached hereto as Exhibit "C" (the "Statement of

         13.1 Amendment. Neither this Contract nor any provisions hereof may
ever be amended, changed, modified or supplemented except by an agreement in
writing, duly executed by the Party to be charged with the same.


         13.2 Assignment. Either Party may assign its rights, titles or
interests hereunder to any individual, bank, trustee, company or corporation
("Lender") as security for any note, notes, bonds or other obligations or
securities of such assignor. In the event of such an assignment by Bay Gas,
Shipper shall provide such financial information to the Lender, which is the
assignee of Bay Gas as may be reasonably requested by Bay Gas. Except as
specified in the first sentence of this Section 13.2, no assignment shall be
made without the written consent of the other Party hereto, which consent shall
not be unreasonably withheld; provided, however, that either Party may assign
this Agreement to a subsidiary with reasonably sufficient creditworthiness, as
the Parties shall agree, which is a successor owner or operator or agent upon
written notice to, but without the prior consent of, the other Party. Subject to
the foregoing, this Contract shall be binding upon and inure to the benefit of
the respective successors and assigns. No assignment provided for hereunder

Party hereto nor shall the assignee be relieved of its obligations hereunder
without the express written consent of the non-assigning Party.

         13.3     Invalid Provision.  In the event one or more of the provisions
contained herein shall be held to be invalid, illegal, or unenforceable in any
respect, such invalidity, illegality, or unenforceability shall not affect any

                                       10


<PAGE>   12






other provision hereof and this Agreement shall be construed as if such invalid,
illegal, or unenforceable provision had never been contained herein, provided
that the deletion of such invalid, illegal or unenforceable provision does not
materially change the intended nature and risk of the services provided
hereunder.

         13.4 General Services Administration Regulation. Bay Gas agrees to
comply with the provisions attached hereto as Exhibit "E" and made a part
hereof.

         IN WITNESS WHEREOF, the Parties have executed this Contract in one or
more copies or counterparts, each of which shall constitute and be an original

written.

                                   SECTION II.

A.   Nominations. Shipper shall furnish to Bay Gas a nomination on a form
     acceptable to Bay Gas. All quantities shall be expressed in MMBtu per Day
     and shall separately state Points of Receipt, Points of Delivery or Points
     of Redelivery.

     1.   Shipper must deliver the nominations to Bay Gas by 11:30 A.M. Central


                                        2

<PAGE>   17






          ClockTime the working day prior to gas flow. Shipper may submit
          nominations after such deadline up to 1:00 P.M. Central Clock Time for
          the upcoming gas day. However, if acceptance of Shipper's nomination
          submitted between 11:30 and 1:00 P.M. Central Clock Time would exceed
          Shipper's Maximum Daily Injection Quantity or Maximum Daily Withdrawal
          Quantity or Maximum Storage Quantity or Maximum Daily Transportation
          Quantity, or would cause interruption of another shipper's scheduled
          service, then such nomination will be accepted or rejected by Bay Gas
          at Bay Gas' sole discretion.

     2.   Shipper may submit, and Bay Gas will accept, nominations after 1:00
          P.M. for the upcoming gas day or during the current gas day on a best
          efforts basis. If acceptance of Shipper's nomination for service would
          exceed Shipper's Maximum Daily Injection Quantity or Maximum Daily
          Withdrawal Quantity or Maximum Storage Quantity or Maximum Daily
          Transportation Quantity, or would cause interruption of another
          shipper's scheduled service, then such nomination will be accepted or
          rejected at Bay Gas' sole discretion.

     3.   Nominations made in accordance with this Section II A shall not become
          effective until Bay Gas has confirmed the nominated storage receipts
          (injections) and deliveries (withdrawals), or transportation
          deliveries and redeliveries, with upstream and downstream parties.
          Shipper shall designate the appropriate person(s) with authority to
          confirm nominations and to resolve allocation issues on a
          24-hour-basis.

     4.   The parties intend that the volumes of gas received or delivered or
          redelivered will be equal to the confirmed nominations. To the extent
          that gas quantities actually received or delivered or redelivered may
          be greater than or less than the confirmed nominations, the parties
          intend that such variance will be treated in accordance with an
          Accounting Allocation Agreement entered into between the parties.

     5.   Bay Gas shall not be obligated, during any hour, to receive or to
          deliver or to redeliver a total volume of gas in excess of one
          twenty-fourth (1/24th) of the lesser of (a) Shipper's aggregate
          Maximum Daily Injection Quantity or Maximum Daily Withdrawal Quantity,
          or Maximum Daily Transportation Quantity or (b) Shipper's accepted
          nomination volumes. The parties intend that from time to time Shipper
          and Bay Gas may mutually agree to a flow rate above or below a uniform
          hourly rate.

B.   Balancing. Bay Gas will accept for storage injection or deliver for
     withdrawal, or for transportation delivery and redelivery, on a daily
     basis, volumes thermally equivalent to volumes nominated and scheduled,
     less appropriate compressor fuel and lost-and-unaccounted-for gas
     (collectively called "Company Use") charges, unless otherwise mutually
     agreed to in writing. All imbalances between actual and nominated


                                        3

<PAGE>   18






     injection volumes or withdrawal volumes, or between delivery volumes and
     redelivery volumes, shall be treated as imbalance under, and received in
     accordance with, the Storage or Transportation Service Agreement(s) under
     which the gas in question is delivered to or from the storage or
     transportation facilities. Gas delivered to Bay Gas for withdrawal or
     redelivery hereunder on each day shall be at constant uniform rates as
     practicable throughout such day.

     1.   If Shipper is advised by any upstream third party of the need to
          reduce or suspend deliveries of gas scheduled for delivery to or from
          storage, or for transportation delivery and redelivery, Shipper shall
          immediately notify Bay Gas orally, and shall confirm such notification
          in writing, of such reduction or suspension.

     2.   Nothing in this Section II B shall limit Bay Gas' right to take action
          as may be required to adjust injections or withdrawals of gas,
          including suspending storage services or to adjust deliveries and
          redeliveries, including suspending transportation services, in order
          to alleviate conditions that threaten the integrity of its system.

     3.   In the absence of an executed Accounting Allocation Agreement between
          Shipper and Bay Gas as described in Section II A. 4, balancing
          procedures shall be as specified in this Section II B. If an
          Accounting Allocation Agreement is in effect between Shipper and Bay
          Gas, such Agreement shall take precedence over the provisions
          specified in this Section II B.

     4.   If there is more than one supply source (whether at a single or at
          multiple Points of Receipt or Delivery) nominated to be received for
          Storage or Transportation, the nomination will identify how and which
          supply source(s) should be allocated by means of a Receipt
          Pre-Determined Allocation ("RPDA") specified in the nomination. In
          accounting for the volumes delivered or redelivered by Bay Gas, in
          circumstances where multiple services are provided at any Point of
          Delivery or Redelivery, the sequence of volumes delivered shall be
          determined by the Delivery Pre-Determined Allocation ("DPDA")
          specified by Shipper in its most recent nomination. The nomination
          will identify which supply source(s) should be allocated in the event
          gas is not or cannot be delivered or redelivered as nominated.

     5.   To the extent feasible, all volumes received by or delivered to Bay
          Gas at a Point of Receipt or Delivery shall be allocated in accordance
          with the confirmed nominations for that point. In the event the actual
          volumes received by Bay Gas do not equal the confirmed nominations for
          that point, any underage or overage will be allocated as follows:

               (a)  First, in accordance with the effective RPDAs submitted by
                    Shipper (or Shipper's suppliers). Shipper agrees that such
                    an allocation is binding on Shipper.


                                        4

<PAGE>   19







               (b)  Then, if there is no effective RPDA, pro rata to the extent
                    applicable based on confirmed nominations, as applicable.
                    Shipper agrees that such an allocation is binding on
                    Shipper.

     6.   To the extent feasible, all volumes delivered or redelivered by Bay
          Gas at a Point of Delivery or Redelivery shall be allocated in
          accordance with the confirmed nominations for that point. In the event
          the actual volumes delivered by Bay Gas do not equal the confirmed
          nominations for that point, any underage or overage will be allocated
          as follows:

               (a)  First, in accordance with the effective DPDAs submitted by
                    Shipper (or Shipper's suppliers). Shipper agrees that such
                    an allocation is binding on Shipper.

               (b)  Then, if there is no effective DPDA, pro rata to the extent
                    applicable based on confirmed nominations, as applicable.
                    Shipper agrees that such an allocation is binding on
                    Shipper.

     7.   Each Shipper shall be responsible for ensuring that its suppliers
          submit Pre-Determined Allocations ("PDAs", which include RPDAs or
          DPDAs) as provided herein using a form acceptable to Bay Gas. Unless
          otherwise agreed, all PDAs must be submitted to Bay Gas via facsimile
          or other agreed upon electronic means on or before the date the PDA is
          to be effective. Such PDA shall specify how any underage or overage
          from the confirmed nominated volumes should be allocated among the
          entities listed on the PDA. Bay Gas shall acknowledge receipt and
          acceptance of the PDA by returning acknowledgment of the PDA to
          Shipper via mutually agreeable means. Bay Gas acceptance is contingent
          on Bay Gas being able to administer the allocation submitted by the
          Shipper.

     8.   To the extent that actual injections or actual withdrawals, or actual
          deliveries or actual redeliveries, for each Shipper do not exactly
          match confirmed nominations for any day, Bay Gas will attempt to
          balance any such differences among Bay Gas and the upstream or
          downstream entities, without impacting Shipper, whenever possible. If
          an upstream or downstream entity requires a Balancing Agreement for
          which any fee is required, Shipper agrees to reimburse Bay Gas for any
          incurred expenses.


C.   Storage Balance Reconciliation. To the extent Shipper and Bay Gas agree, in
     writing, that imbalances may be accounted for under the Shipper's Storage
     Service Agreement, and to the extent Shipper has sufficient storage
     capacity, Bay Gas will issue a formal storage balance notice to Shipper by
     the 20th of the month following the injection/withdrawal month ("the Notice
     Month"), reflecting the effect of Shipper's storage balance or any
     imbalance. Shipper understands and


                                        5

<PAGE>   20






     agrees to contact or cause to be contacted, the parties that deliver
     injection volumes to Bay Gas, or receive withdrawal volumes from Bay Gas,
     for the Shipper's account to confirm any imbalance.

     Following the termination of the Storage Service Agreement, Shipper shall
     be required to either (a) transfer title to any volumes of gas in storage
     to a third party with whom Bay Gas has a Storage Service Agreement, with
     such transfer to be subject to any injection conditions or charges
     applicable to such third party, or (b) withdraw such volumes from storage
     within a sixty (60) day balancing period after the determination by Bay Gas
     that any such volumes exist, or within such longer period of time mutually
     agreed upon by Shipper and Bay Gas. Shipper agrees that at the end of the
     above sixty (60) day balancing period, Bay Gas will, for any storage
     volumes not withdrawn, take title to such gas and such title is to pass
     automatically without cost to Bay Gas.

D.   Excess Deliveries. In the event that Shipper, from time to time, desires to
     have injected into or withdrawn from storage, or to have transported, or to
     have transported, quantities of gas in excess of the Maximum Daily
     Injection Quantity or Maximum Daily Withdrawal Quantity, or Maximum Daily
     Transportation Quantity, respectively, which Bay Gas is obligated to accept
     or deliver or redeliver under storage or transportation arrangements for
     Shipper on any day under a Storage or Transportation Service Agreement,
     Shipper may request injection or withdrawal or transportation of such
     excess gas, and Bay Gas in its sole discretion may accept or deliver or
     redeliver all or any part of such gas subject to the restrictions of these
     General Terms and Conditions.

                                  SECTION III.
                           Construction of Facilities

         Under no circumstances shall Bay Gas be obligated to construct or add
facilities to receive or deliver or redeliver gas under a Storage or
Transportation Service Agreement, or to increase the capacity of Bay Gas'
pipeline system or storage or transportation facilities. Upon Shipper's written
request to evaluate connections of new facilities, Bay Gas will prepare and
submit to Shipper a construction cost estimate. All new or additional facilities
that may be required for the delivery of acceptable gas to Bay Gas, or for the
delivery or redelivery of gas to the receiving party or parties will be
constructed, maintained, owned and operated by Bay Gas, except as may otherwise
be expressly agreed in writing. The design and installation of all facilities
shall be in accordance with the specifications then used by Bay Gas for like or
similar facilities. Shipper shall bear the cost of all such new connections,
unless otherwise mutually agreed.


                                   SECTION IV.
                                 Rate Adjustment

A.   Rates charged for services shall be negotiated between Bay Gas and Shipper.
     Bay Gas reserves the right to seek authorization from the


                                        6

<PAGE>   21






     Federal Energy Regulatory Commission ("FERC") or other appropriate agency
     to increase, decrease or restructure the rates (including market based
     rates), and Company Use charges in effect at any time as may be found
     necessary to assure Bay Gas' right to charge and collect fair and equitable
     rates within the meaning of Section 311 (a)(2) of the Natural Gas Policy
     Act of 1978 ("NGPA") and the FERC's rules and regulations thereunder.
     Nothing herein contained shall be construed to deny any Shipper any rights
     which it may have under FERC rules and regulations, including the right to
     participate fully in rate proceedings by intervention or otherwise to
     contest changes in rates and Company Use charges in whole or part. In
     addition to the rates above, Shipper shall pay in advance all applicable
     state and federal filing, reporting and application fees incurred by Bay
     Gas for providing such services.

B.   Bay Gas may at any time provide firm or interruptible storage services at
     different rates from the market based rates approved by the FERC for Bay
     Gas' NGPA Section 311(a)(2) services. Nothing herein shall obligate or
     require, or be construed to obligate or require, Bay Gas to offer or
     continue such different rates.


                                   SECTION V.
                             Regulatory Requirements

         Bay Gas' interstate services shall be in accordance with and subject to
the requirements of Section 311(a)(2) of the NGPA and the rules and regulations
of the FERC thereunder. Bay Gas' intrastate services shall be in accordance with
and subject to the laws, rules and regulations of the State of Alabama.

         Bay Gas agrees to proceed with reasonable diligence during the term of
the Storage or Transportation Service Agreement with the filing for and
prosecution of any authorizations as may be required for the storage or
transportation of the gas hereunder or the rate(s) charged therefor. Bay Gas
reserves the right to pursue any necessary regulatory filings with FERC and any
other governmental or regulatory body having jurisdiction in such matter as it
deems to be in its best interest, including the right to file whatever pleadings
and motions it deems desirable. In the event Bay Gas has obtained such necessary
regulatory authorization, but the terms and conditions are significantly
different than those terms originally filed with the regulatory agency, or in
the event FERC rejects or modifies Bay Gas' Statement of Conditions for NGPA
Section 311(a)(2) Gas Storage and Transportation Services, as same may be
amended by Bay Gas from time to time, Bay Gas shall pursue other reasonable
options to continue providing such services or, at Bay Gas' option, shall
terminate such services as provided in Article VII, Right to Terminate Services,
of Bay Gas' Statement of Conditions.




                                   SECTION VI.
                                    Pressures


                                        7

<PAGE>   22







         Bay Gas shall operate its storage facilities at pressures which will
accommodate the withdrawal of gas in accordance with Bay Gas' outstanding firm
service storage commitments. Bay Gas shall operate its transportation facilities
at pressures which will accommodate the redelivery of gas in accordance with Bay
Gas' outstanding firm service transportation commitments. Shipper shall be
obligated to deliver gas for injection or for transportation, at a pressure
sufficient for Bay Gas to transport such gas to and inject into its storage
facility, or to transport such gas for redelivery, recognizing that the amount
of such pressure will vary based on the operation of the Bay Gas pipeline.


                                  SECTION VII.
                                   Measurement

A.   The gas received for injection or delivered for withdrawal at the storage
     facilities, or delivered or redelivered at the transportation facilities,
     shall be measured with meters constructed and installed, and whose
     computations of volume are made, in accordance with the provisions of
     ANSI-API 2530-AGA-3, latest revision as adopted by Bay Gas.

B.   The temperature of the gas shall be determined by a recording thermometer
     so installed that it will record the temperature of the gas flowing through
     the meters. The average of the record to the nearest one degree (1 degree)
     Fahrenheit, obtained while gas is being delivered, shall be the applicable
     flowing gas temperature for the period under consideration. For all
     measurement of gas required in this Section, the BTU content per cubic foot
     shall be determined for a cubic foot of gas at a temperature of sixty
     degrees (60 degrees) Fahrenheit, at an absolute pressure of fourteen and
     seventy-three hundredths (14.73) pounds per square inch on a dry basis.

C.   The BTU, specific gravity, carbon dioxide, and nitrogen content of the gas
     shall be determined by the use of an on-line chromatograph or by a
     chromatographic analysis of the gas obtained by a continuous sample or spot
     sampling method. The results of any sample taken with an on-line
     chromatograph shall be applied to the month in which the sample was taken.

D.   Adjustment for the effect of supercompressibility shall be made according
     to the provisions of the latest version of either NX-19 or AGA Committee
     Report No. 8, as required by Paragraph A. of this Section and as adopted by
     Bay Gas, for the average conditions of pressure, flowing temperature, and
     specific gravity at which the gas was measured during the period under
     consideration and with the proportionate values of carbon dioxide and
     nitrogen in the gas delivered included in the computation of the applicable
     supercompressibility factors.

E.   If at any time during the term hereof a new method or technique is
     developed with respect to gas measurement or the determination of the
     factors used in such gas measurement, such new method or technique may


                                        8

<PAGE>   23






     be substituted for the gas measurement set forth in this Section on the
     date such method or technique is adopted by Bay Gas.



                                  SECTION VIII.
                         Measuring Equipment and Testing

A.   General. The construction, ownership, operation and maintenance of any
     measuring equipment necessary to accomplish the storage receipt of gas for
     injection by Bay Gas for the account of Shipper and the delivery of gas
     withdrawn by Bay Gas for the account of Shipper, or the transportation
     delivery of gas to Bay Gas for the account of Shipper and the redelivery of
     gas by Bay Gas for the account of shipper shall be the responsibility of
     Bay Gas. Shipper shall at all reasonable times have access to the premises
     of Bay Gas for inspections, insofar as such premises are connected with any
     matter or thing covered hereby. The operation of measuring equipment and
     changing of charts shall be done only by the employees or agents of Bay
     Gas.

B.   Testing and Repair of Equipment.

     1.   Bay Gas shall keep its own measuring equipment accurate and in repair,
          making periodic tests to verify the condition of meter tubes, orifice
          plate, and chart recorder or flow computer. Bay Gas agrees to give
          Shipper(s) seven (7) calendar days notice prior to such tests of the
          measuring equipment so that, if desired, Shipper(s) may have its
          representative present. Shipper(s) shall have the right to challenge
          the accuracy of Bay Gas' equipment, and when challenged, the equipment
          shall be tested, calibrated and, if required, repaired by Bay Gas, the
          cost of such special test to be borne by Bay Gas if the percentage of
          the inaccuracy is found to be more than two percent (2%), but if the
          percentage of inaccuracy is found to be two percent (2%) or less, the
          cost of such special test shall be borne by the Shipper(s). If upon
          any test the percentage of inaccuracy is found to be in excess of two
          percent (2%), registrations thereof shall be corrected for a period
          extending back to the time such inaccuracy occurred, if such time is
          ascertainable, and if not ascertainable, then back one-half (1/2) of
          the time elapsed since the last date of calibration. Any measuring
          equipment found to be measuring inaccurately by one percent (1%) or
          more shall be adjusted at once to read accurately.

     2.   If, for any reason, the meter(s) are out of service or out of repair
          so that the amount of gas received or delivered cannot be ascertained
          or computed from the readings thereof, the gas received or delivered
          during the period such meter(s) are out of service or out of repair
          shall be estimated and agreed upon by the parties hereto by the use of
          the first applicable of the following methods:



                                        9

<PAGE>   24






               (a)  By comparative utilization of any like check measuring
                    equipment if such check measuring equipment can be proven
                    and verified to be measuring accurately; or

               (b)  By computing the error if the percentage of error is
                    ascertainable by calibration, test or mathematical
                    calculation; or

               (c)  By estimating the quantity received or delivered by
                    reference to actual receipts or deliveries during preceding
                    periods under similar conditions when Bay Gas' measuring
                    equipment was registering accurately.

C.   Inspection of Charts and Records. The charts and records from the measuring
     equipment shall remain the property of Bay Gas and shall be kept on file
     for a period of time not less than two (2) years from the end of the
     calendar year in which the charts and records were generated or prepared.
     At any time within such period, upon written request by Shipper, records or
     charts from the measuring equipment, together with calculations therefrom,
     will be submitted for Shipper's inspection and verification subject to
     return to Bay Gas within thirty (30) days from receipt thereof. All
     inquiries regarding this Section VIII, including but not limited to,
     measurement charts, records or audits of charts and records, shall be
     directed to Bay Gas.



                                   SECTION IX.
                                     Quality

         The gas delivered by either party to the other hereunder shall meet or
exceed the quality specifications of the transporting pipeline which receives or
delivers such gas to the other party hereunder.


                                   SECTION X.
                     Billing, Accounting, Taxes and Reports

A.   Billings and Payments.

     1.   For the purpose of billing and accounting for the gas delivered
          hereunder, the day shall begin at 9:00 a.m. Central Clock Time and
          extend to 9:00 a.m. the following day, and the month (hereinafter
          called "billing month") shall begin at 9:00 a.m. Central Clock Time on
          the first (1st) day of the calendar month and extend to 9:00 a.m. on
          the first (1st) day of the following calendar month.

     2.   Bay Gas shall render to its Shippers, by mail or facsimile, on or
          before the first (1st) day of each month an invoice setting forth the
          demand charges as applicable. Within ten (10) days from the date of
          the invoice, Shipper agrees to make payment to Bay Gas by wire
          transfer to the AmSouth Bank of Alabama, crediting Bay Gas'


                                       10

<PAGE>   25






          account number 83794638 for such firm demand charges for the account
          of Shipper at the Delivery Point(s) during the current month.

     3.   On or before the fifteenth (15th) day of each calendar month, Bay Gas
          shall render or cause to be rendered, by mail or facsimile, to all
          Shippers an invoice of the amount due for the preceding month setting
          forth the total quantity of gas (1) received by Bay Gas from Shipper
          for injection into the storage facilities, or delivered by shipper to
          Bay Gas for transportation; (2) delivered by Bay Gas to Shipper for
          withdrawal from the storage facilities, or redelivered by Bay Gas to
          Shipper after transportation; (3) gas balance at the beginning and end
          of the injection/withdrawal, or transportation, month and (4) the
          rates and charges for storage or transportation services hereunder
          during such billing month. Billings for volumes transported shall be
          determined on a dry basis.

     4.   Within ten (10) days from the date of the fifteenth (15th) day
          invoice, Shipper shall pay Bay Gas the amount due for all gas
          injected, withdrawn or stored, or transported, by Bay Gas for the
          account of Shipper during the injection/withdrawal, or transportation,
          month. Payments to Bay Gas shall be made either by wire transfer to
          the AmSouth Bank of Alabama, crediting Bay Gas' account number
          83794638, or by check such that funds are available to Bay Gas on or
          before the tenth (10th) day after the date of the invoice. If
          rendering of an invoice by Bay Gas is delayed after the fifteenth day
          of the month, then the time of payment shall be extended accordingly
          unless Shipper is responsible for such delay.

B.   Late Payment. In the event Shipper shall fail to pay any amount due Bay Gas
     when the same is due, Bay Gas shall have the option of accruing interest at
     a varying rate per annum (based on a year of 365 or 366 days, as the case
     may be) which shall be one hundred fifteen percent (115%) of the prime rate
     charged by the AmSouth Bank of Alabama to its largest and most creditworthy
     commercial borrowers on ninety (90) day commercial loans (but in no event
     greater than the maximum rate of interest permitted by law) with
     adjustments in such rate, for any period during which the same shall be
     overdue, such interest to be paid when the amount past due is paid. Shipper
     shall not be required to pay interest on any amount billed which is in good
     faith disputed in writing by Shipper and is ultimately determined to be in
     error; provided, however, interest shall be due if such amount billed is
     found not to be in error. If a portion of an invoice is disputed, Shipper
     shall pay when due the portion of the invoice not in dispute. If such
     failure to pay continues for thirty (30) days after the payment due date,
     Bay Gas may suspend deliveries of gas, subject to Bay Gas providing
     forty-eight (48) hours written notice, during normal working hours, of such
     intention to suspend deliveries; provided, however, that if Shipper, in
     good faith, disputes the amount of any such bill or part thereof and pays
     to Bay Gas such amounts as Shipper concedes to be correct, and


                                       11

<PAGE>   26






     furnishes and maintains a good and sufficient surety bond in an amount, and
     with sureties satisfactory to Bay Gas, conditioned upon the payment of any
     amounts ultimately found due upon such bills after a final determination,
     then Bay Gas shall not be entitled to suspend further delivery due to
     failure to pay such bills. In the event Shipper's financial position
     significantly deteriorates from that on the execution date of the Storage
     or Transportation Service Agreement, advance cash payments or acceptable
     security (including but not limited to an irrevocable letter of credit from
     a financial institution in an amount acceptable to Bay Gas) shall be given
     by Shipper upon demand of Bay Gas. Bay Gas may, without waiving any other
     rights or remedies it may have, withhold further delivery until such
     payment is received. In the event Bay Gas pursues collection on late
     payment, Shipper shall be liable for all expenses and costs, including
     court costs and attorneys' fees, incurred as a result of such failure to
     pay on time.

C.   Tax Reimbursement. Shipper agrees to reimburse Bay Gas for all new taxes
     (federal, state, local or other) that may be levied upon or paid by Bay
     Gas, with respect to the services performed hereunder.

D.   Examination of Books, Records and Charts. Each party shall have the right
     during reasonable working hours to examine the books, records and charts of
     the other party to the extent necessary to verify the accuracy of any
     statement, payment calculations or determinations made pursuant to the
     provisions contained herein. If any such examination shall reveal, or if
     either party shall discover, any error in its own or the other party's
     statements, payment calculations or determinations, then proper adjustment
     and correction thereof shall be made as promptly as practicable thereafter.
     The accuracy of any statement, payment calculations or determinations made
     pursuant to the provisions contained herein shall be conclusively presumed
     to be correct after two (2) years from the end of the calendar year in
     which the charts and records were generated or prepared if not challenged
     in writing prior thereto.



                                   SECTION XI.
                      Possession and Non-Odorization of Gas

         As between Shipper and Bay Gas, Shipper shall be in exclusive control
and possession of the gas deliverable and responsible for any damage or injury
caused thereby until the same shall have been received by Bay Gas for injection
at the storage facilities, or until delivered at the transportation facilities,
and after delivery of the gas for the account of Shipper for withdrawal at the
storage facilities, or after redelivery for the account of Shipper at the
transportation facilities. After delivery of gas for injection or transportation
by Shipper to Bay Gas, and until delivery by Bay Gas to Shipper or Shipper's
designee upon withdrawal or until redelivery after transportation, Bay Gas shall
be in exclusive control and possession thereof and responsible for any injury or
damage caused thereby. Neither Bay Gas nor Shipper assume any obligation to
odorize any gas delivered to the other.

                                  SECTION XII.
                                    Warranty

         Shipper warrants that it will have and maintain good and marketable
title or the right to deliver for a third party owning good and marketable title
all gas tendered for injection, storage and withdrawal under a Storage Service
Agreement, and all gas delivered for transportation under a Transportation
Service Agreement, and that such gas shall be free and clear of all liens and
adverse claims; and each party agrees, with respect to the gas delivered by it,
to indemnify the other against all suits, actions, debts, accounts, damages,
costs (including attorney's fees), losses and expenses arising from or out of
any adverse claims of any and all persons to or against said gas.


                                  SECTION XIII.
                             Government Regulations

A.   All of the provisions of any Storage or Transportation Service Agreement
     are hereby expressly made subject to all present and future applicable
     federal or state laws, orders, rules and regulations of governmental
     authorities having jurisdiction. Except as otherwise provided herein, in
     the event any provision of a Storage or Transportation Service Agreement or
     of these General Terms and Conditions is found to be inconsistent with or
     contrary to any such law, order, rule or regulation, the latter shall be
     deemed to control, and the Storage or Transportation Service Agreement and
     these General Terms and Conditions, to the extent possible, shall be
     regarded as modified accordingly and as so modified shall continue in full
     force and effect.

B.   The parties hereto recognize that a Storage or Transportation Service
     Agreement has been entered into by Bay Gas in the good faith understanding
     that all acts, obligations and services performed by Bay Gas hereunder, and
     the charges therefor, are exempt from the regulation of FERC or any
     successor federal governmental authority, except as presently provided by
     Section 311(a)(2) of the NGPA and FERC's relevant regulations thereunder.
     Bay Gas reserves the right to terminate a Storage or Transportation Service
     Agreement immediately if, in the opinion of counsel for Bay Gas, any act
     shall occur or be seriously threatened which is in any way inconsistent
     with such understanding.

C.   Equal Employment Opportunity. Bay Gas and Shipper agree to comply with any
     and all applicable executive orders and acts pertaining to equal employment
     opportunity.



                                  SECTION XIV.
                                  Force Majeure

A.   In the event of either party being rendered unable, wholly or in part, by
     reason of force majeure to carry out its obligations under any


                                       13

<PAGE>   28






     Storage or Transportation Service Agreement (other than the obligation to
     make payment of amounts due hereunder), it is agreed that such party shall
     give notice and reasonably full particulars of such force majeure, in
     writing or by facsimile, to the other party within a reasonable time after
     the occurrence of the cause relied on, and the obligations of the party
     giving such notice, so far as they are affected by such force majeure,
     shall be suspended during the continuance of any inability so caused, but
     for no longer period, and such cause shall, so far as possible, be remedied
     with all reasonable dispatch.


B.   The term, "force majeure," as employed herein shall mean acts of God;
     strikes, lockouts, or other industrial disturbances; conditions arising
     from a change in governmental laws, orders, rules or regulations; acts of
     public enemy; wars; blockades; insurrections; riots; epidemics; landslides;
     lightning; earthquakes; fires; storms; floods; washouts; arrests and
     restraints of governments and people; civil disturbances; explosions;
     breakage or accident to machinery or lines of pipe; the necessity for
     making repairs, tests or alterations to machinery or lines of pipe;
     freezing of wells or lines of pipe; partial or entire failure of wells,
     processing or gasification and gas manufacturing facilities; and any other
     causes, whether of the kind herein enumerated or otherwise, not within the
     control of the party claiming suspension, and which by the exercise of due
     diligence, such party is unable to prevent or overcome. Such term shall
     likewise include: (a) those instances where either Bay Gas or Shipper is
     required to obtain servitudes, rights-of-way, grants, permits or licenses
     to enable such party to fulfill its obligations under a Storage or
     Transportation Service Agreement; the inability of such party in acquiring,
     at reasonable costs, and after the exercise of reasonable diligence, such
     servitudes, rights-of-way, grants, permits or licenses, and (b) those
     instances where either Bay Gas or Shipper is required to furnish materials
     and supplies for the purpose of constructing or maintaining facilities or
     is required to secure permits or permissions from any governmental agency
     to enable such party to fulfill its obligations under a Storage or
     Transportation Service Agreement; the inability of such party to acquire,
     or the delays on the part of such party in acquiring, at reasonable costs,
     and after the exercise of reasonable diligence, such materials and
     supplies, permits and permissions. Force majeure shall not include failure
     of gas supply due to pricing considerations.

C.   It is understood and agreed that the settlement of strikes or lockouts
     shall be entirely within the discretion of the party having the difficulty,
     and that the above requirement that any force majeure shall be remedied
     with all reasonable dispatch shall not require the settlement of strikes or
     lockouts by acceding to the demands of the opposing party when such course
     is inadvisable in the discretion of the party having the difficulty.



                                   SECTION XV.

                                     Notices

         Except as herein otherwise provided, any communication, notice,
request, demand, statement or bill provided for in a Storage or Transportation
Service Agreement which any party may desire to give to any other party shall be
made in writing and mailed by first class mail to the post office address of the
party intended to receive the same, as the case may be, at the addresses each
respective party shall designate in the Storage or Transportation Service
Agreement or change by subsequent formal written notice to the other. Routine
communications, including monthly statements and payments, may be mailed by
either certified or ordinary first class mail.


                                  SECTION XVI.
                                Creditworthiness

         Bay Gas shall not be required to commence service or, subject to the
following timing provisions, to continue to provide service under a Storage or
Transportation Service Agreement with any Shipper, that (a) is or has become
insolvent; (b) has applied for bankruptcy under Chapter 11 of the Bankruptcy
Code, or which is subject to similar proceedings under state or federal law; or
(c) when requested by Bay Gas to demonstrate creditworthiness, fails to do so in
Bay Gas' reasonable judgment, in light of previous payment experience and the
prudent credit analysis of information available; provided, however, that any
such Shipper that is receiving service shall continue to receive service for a
period of fifteen (15) days after written notice by Bay Gas of any such
circumstance, and shall continue thereafter to receive service if, within such
fifteen (15) day notice period, such Shipper (a) deposits with Bay Gas and
maintains, on account, an amount which would be due for three (3) months service
at the full Maximum Daily Withdrawal Quantity, or the full Maximum Daily
Transportation Quantity, including an amount of the current gas imbalance plus,
an amount equal to the three (3) highest cashout payments, if any, incurred
during the previous twelve months, or (b) furnishes good and sufficient
security, which may include an acceptable standby letter of credit, or monthly
prepayment agreement or other security as reasonably determined by Bay Gas, of a
continuing nature and in an amount equal to such amounts which would be due for
service. If such payment on account or payment security is not received within
such fifteen (15) day notice period, Bay Gas may, without waiving any rights or
remedies it may have, suspend further service for a period of ten (10) days. If
such payment on account or a payment security is not received within such ten
(10) day suspension period, then Bay Gas shall no longer be obligated to
continue to provide service to such Shipper. Further, if such payment on account
or a payment security is not received within sixty (60) days after the end of
such suspension period, Bay Gas may terminate its obligations to provide service
under all agreements between Shipper and Bay Gas, which termination shall not
affect any of Bay Gas' claims or remedies it may have under any Storage or
Transportation Service Agreement.



                                  SECTION XVII.
                                  Miscellaneous

A.   Headings and Subheadings. The headings and subheadings contained in the
     Storage or Transportation Service Agreement are used solely for convenience
     and do not constitute a part of the Storage or Transportation Service
     Agreement between the parties hereto, nor should they be used to aid in any
     manner in construing the Storage or Transportation Service Agreement.

B.   Successors and Assigns. The Storage or Transportation Service Agreement
     shall be binding upon and inure to the benefit of the respective successors
     and assigns of the parties hereto, but no assignment shall relieve any
     party of its obligations hereunder unless such party is expressly released
     in writing from said obligations by the party to which it is obligated.

C.   Entire Agreement. The Storage or Transportation Service Agreement, the
     Statement of Conditions for NGPA Section 311(a)(2) for Gas Storage and
     Transportation Services, and these General Terms and Conditions constitute
     the entire agreement of the parties hereto as to the matters contained
     herein, and there are no oral promises, agreements or warranties affecting
     same.

D.   Non-Waiver. The waiver of any default or right to require performance under
     a Storage or Transportation Service Agreement shall not operate as a waiver
     of any future default or right to require performance, whether of like or
     different character or nature.

E.   Jurisdiction and Venue. The parties agree that a Storage or Transportation
     Service Agreement shall be governed by and construed in accordance with the
     laws of the State of Alabama, excluding any conflicts of law, rule or
     principle that might refer such construction to the laws of another state
     and that venue shall be in the State of Alabama for services performed in
     Alabama, with respect to any cause of action brought under or with respect
     to a Storage or Transportation Service Agreement.

F.   Confidentiality. The terms of any Storage or Transportation Service
     Agreement shall be kept confidential by the parties except to the extent
     that any information must be disclosed to a third party as required by law,

                                   EXHIBIT "C"

                            BAY GAS STORAGE COMPANY's
                           STATEMENT OF CONDITIONS FOR
                           NGPA SECTION 311 (a)(2) GAS
                       STORAGE AND TRANSPORTATION SERVICES

                            Dated December 22, 1998.


         Bay Gas Storage Company, Ltd. ("Bay Gas"), a natural gas storage public
utility that qualifies as an intrastate pipeline company providing services
within the meaning of Natural Gas Policy Act of 1978 ("NGPA") Section 2 (16) and
Section 284.1 (a) of the Federal Energy Regulatory Commission's ("Commission")
regulations, files this amended Statement of Conditions For NGPA Section 311
(a)(2) Gas Storage and Transportation Services, pursuant to the Commission's
regulations. 18 C.F.R. Section 284.123 (e). Firm and interruptible gas storage
and transportation-only services, on terms and conditions authorized by the
Commission and accepted by Bay Gas, shall be provided by Bay Gas pursuant to
NGPA Section 311 (a)(2), 15 U.S.C. Section 3371 (a)(2), and the Commission's
implementing Orders, Rules and Regulations, to qualified Shippers that comply
with the conditions set forth in this Statement and with the terms and
conditions contained in Bay Gas' Storage or Transportation Service Agreement
executed with Shipper.


                                       I.

                       BAY GAS' BASIC STATUS AND FUNCTION

         Bay Gas is a gas storage public utility, certificated by the Alabama
Public Service Commission and subject to regulation by that Commission, which
qualifies as an intrastate pipeline company providing storage and transportation
services within the meaning of NGPA Section 2 (16) and Section 284.1 (a) of this
Commission's regulations. Any such NGPA Section 311 (a)(2) services that Bay Gas
provides will be consistent with, and shall not infringe on, Bay Gas' status and
function as a non-Federal-jurisdictional intrastate pipeline, and shall not
subject Bay Gas to this Commission's Natural Gas Act jurisdiction. 18 C.F.R.
Section 284.3.




<PAGE>   32






                                       II.

                               QUALIFIED SHIPPERS

         Besides other conditions contained in this Statement, Bay Gas' services
are available only to a Shipper that enters into a Service Agreement mutually
acceptable to Bay Gas and Shipper. All transactions for storage or
transportation of gas that has flowed, or will flow, in interstate commerce must
qualify under NGPA Section 311 (a)(2) and 18 C.F.R. Part 284 of Subchapter I.
If, in the opinion of Bay Gas' counsel, such qualified status of Shipper or its
proposed transaction is in doubt, then Shipper must apply for and receive a
final, non-appealable ruling from this Commission, or successor agency thereto,
affirming such qualifying status of Shipper and its proposed transaction, prior
to commencement of services by Bay Gas.

                                      III.

                CAPACITY AVAILABILITY, SCHEDULING AND ALLOCATIONS
                                AND CURTAILMENTS

A.   Capacity Availability

     1.   Storage service shall be conditioned on availability of sufficient
          injection rate capacity, field storage capacity and withdrawal rate
          capacity (collectively called "Capacity," and including pipeline
          transportation service capacity) to perform the service in accordance
          with the terms and conditions set forth in this Statement of
          Conditions without detriment or disadvantage to services by or for the
          account of Bay Gas. Transportation service shall be conditioned on
          availability of sufficient Capacity to perform the service in
          accordance with the terms and conditions set forth in this Statement
          of Conditions without detriment or disadvantage to services by or for
          the account of Bay Gas. Bay Gas reserves all rights to retain
          sufficient Capacity for its intrastate, non-Federal-jurisdictional
          firm and interruptible services and for its operational swings
          attributable to firm and interruptible storage services prior to
          making Capacity available


<PAGE>   33






          by contract to NGPA Section 311 (a)(2) Shippers. Once Capacity is made
          available to NGPA Section 311 (a)(2) Shippers, such Capacity shall be
          scheduled, allocated or curtailed only as set forth in Sections III. B
          and C here.

     2.   Storage service availability further shall be conditioned on Bay Gas
          receiving an acceptable market value, in Bay Gas' sole judgment, for
          such storage services, determined when a request for storage service
          is received. Bay Gas reserves all rights to refuse a request for
          storage service that, in Bay Gas' sole judgment, might provide less
          than market value. Apart from such Bay Gas judgment as to market
          value, Bay Gas' judgment shall be exercised on a non-discriminatory
          basis.

     3.   Criteria applied to requests for NGPA Section 311 (a)(2) services
          shall be the same as criteria applied to requests for intrastate,
          non-Federal-jurisdictional services.

     4.   Shipper shall be responsible for making all arrangements for its
          transportation of gas to be injected into or withdrawn from storage
          through Bay Gas' storage services. Bay Gas reserves all rights to
          refuse storage service for any otherwise qualified Shipper if Bay Gas
          determines that such storage would be detrimental to Bay Gas' storage
          operations in any way, including, without limitation, Bay Gas' storage
          compression and affected processing operations.

B.       Scheduling and Allocations

         Bay Gas shall schedule contracted services according to these
         principles:

                  1. Nomination deadlines shall be as prescribed in Bay Gas'
                  General Terms and Conditions. 

                  2. Bay Gas will be under no obligation to schedule the
                  injection of gas into storage or the withdrawal of gas from
                  storage until Bay Gas has confirmed the availability of
                  Shipper's transportation




<PAGE>   34






          service to or from Bay Gas' storage services for the gas concerned.
          Subject to the foregoing subsection "1." and this subsection "2.",
          firm storage and transportation services shall be scheduled before
          interruptible services in all instances, regardless of the relative
          service rates to be paid.

     3.   In-field transfer of title (transfer of gas balances in the storage
          field between storage service agreements) may be made only with Bay
          Gas' approval.

     4.   Interruptible storage service Shippers paying a higher Unit Rate, as
          defined in Bay Gas' General Terms and Conditions, shall be scheduled
          ahead of interruptible storage service Shippers paying a lower Unit
          Rate. If, because of changes in available Capacity at any time, Bay
          Gas is required to reschedule interruptible Shippers that are
          injecting, storing or withdrawing gas and are paying the same Unit
          Rate, then the Capacity shall be rescheduled pro rata based on
          applicable contract quantities for said Shippers.

     5.   Bay Gas reserves the right to interrupt service to an interruptible
          Shipper injecting, storing or withdrawing gas, in order to enable Bay
          Gas to provide service to another, bumping, interruptible Shipper
          injecting, storing or withdrawing gas, if such Shipper is paying a
          higher Unit Rate to Bay Gas.

     6.   All overrun volumes in excess of a storage service Shipper's contract
          quantities nominated for delivery by Shipper shall be scheduled
          according to the above subsections "4." and "5." only after all other
          storage service Shippers' nominated volumes equal to or less than each
          Shippers' Maximum Daily Injection Quantity or Maximum Daily Withdrawal
          Quantity are scheduled.

     7.   Bay Gas may reschedule Capacity on a daily basis, or on such other
          periodic basis as is necessary for Bay Gas to recognize the priority
          of new storage or transportation service Shippers or any changes in
          the priorities of existing such Shippers, and to


<PAGE>   35






                  conform to its storage system operational requirements. Such
                  priorities or changes will include, but will not be limited
                  to, those instances involving a storage service Shipper paying
                  a higher Unit Rate for interruptible service and firm storage
                  service Shippers changing volumes within their Maximum Daily
                  Injection Quantity or Maximum Daily Withdrawal Quantity.
                  However, such changes in scheduling shall not at any time bump
                  any existing firm Shipper.

         C.       Curtailments

     1.      General. If curtailment of storage or transportation service is
             required, volumes shall be curtailed in the reverse order of the
             priority in effect at the time of curtailment established during
             scheduling as set forth in Section "III. B" above. Intrastate,
             non-Federal-jurisdictional firm and interruptible services shall be
             curtailed in a manner determined solely by Bay Gas, but in no event
             shall such curtailments have a different priority than similar
             types of services for NGPA Section 311 (a)(2) Shippers.

     2.      Reduction of Services. Without limitation to the foregoing, Bay Gas
             shall have the right to reduce receipts, deliveries, injections or
             withdrawals of gas on any day below a storage service Shipper's
             Maximum Daily Injection Quantity or Maximum Daily Withdrawal
             Quantity, or below the storage rights applicable, for repair,
             overhaul, replacement or construction of pipelines, compressors,
             metering, regulating or other production, gathering and
             transmission facilities and equipment, or to maintain system
             integrity; provided, however, that with respect to routine repair
             and maintenance, Bay Gas will implement restrictions for scheduling
             purposes only, not for curtailment, and will attempt to schedule
             such activity during a period when it will not result in limitation
             of firm service or when such limitation will be




<PAGE>   36






          minimized, and after consulting with the Shippers that could be
          affected.

     3.   Notice of Curtailment. For shippers under all firm services, Bay Gas
          shall provide notice of any curtailment as far in advance as feasible.
          Services reserved by Bay Gas for system operations shall be curtailed
          last, in consideration of the need to preserve system integrity. If
          capacity is curtailed and two or more firm Shippers have the same
          priority according to this Section "III. C", firm Shippers shall be
          allocated their pro rata share of capacity based on their Maximum
          Daily Injection Quantity or Maximum Daily Withdrawal Quantity or
          Maximum Daily Transportation Quantity, as applicable. If firm Shippers
          nominate fewer than their respective curtailment period entitlements,
          the difference shall be allocated pro rata among those firm Shippers
          with unsatisfied nominations. All non-firm Shippers shall be allocated
          their pro rata share of Capacity based on their nominations in effect
          at the time of the curtailment.

     4.   Limitation of Firm Services. While firm services are not ordinarily
          interrupted by nominations for firm service within Shipper's Maximum
          Daily Injection Quantity or Maximum Daily Withdrawal Quantity or
          Maximum Daily Transportation Quantity, Bay Gas may decline to schedule
          firm service for any of the following reasons:

               (a)  if Shipper tenders gas which does not conform to applicable
                    pressure requirements of the Storage or Transportation
                    Service Agreement

               (b)  if Shipper tenders gas which does not conform to the gas
                    quality requirements of both the upstream and downstream
                    entities' gas quality requirements

               (c)  for reasons of force majeure

               (d)  due to routine repair and maintenance to be reasonably
                    determined by Bay Gas



<PAGE>   37






               (e)  due to delinquency in payment by Shipper

               (f)  to rectify imbalances or to conform physical flows to
                    nominations

               (g)  to maintain system integrity, or

               (h)  if there is a dispute over title, ownership or right to
                    tender, receive or deliver gas.


                                       IV.

                         MINIMUM STORAGE SERVICE VOLUME

         Bay Gas shall not be obligated to furnish storage service to any
Shipper whose average daily gas volume tendered for storage in a given month is
less than 100 MMBtu per day. Such storage Shipper's obligation to tender gas for
delivery shall be suspended and modified for the time and to the extent that Bay
Gas does not accept deliveries due to Shipper's inability to deliver such
minimum average daily volume. If the amount of gas subsequently tendered for
delivery once again is less than such minimum average daily volume, Bay Gas
shall have the right to cancel the Storage Service Agreement at any time on
thirty (30) days written notice to Shipper. Bay Gas shall be deemed released
from all obligations and liabilities, direct or indirect, under such Storage
Service Agreement on the effective date of such a cancellation.


                                       V.

                              RECEIPT AND DELIVERY

         Bay Gas shall have sole operational control over the injection of gas
into, the retention of gas within, and the withdrawal of gas from, Bay Gas'
system storage facilities. A Shipper seeking to direct gas into storage shall
nominate "Storage" as the Point of Delivery on Bay Gas' system and shall
identify the number of the Storage Service Agreement to be used for the receipt
of such gas into storage. A Shipper seeking to withdraw gas from storage shall
nominate "Storage" as the Point of Redelivery from Bay Gas' system and shall
identify the number of the Storage Service Agreement under which the gas is to
be withdrawn from storage. Bay Gas shall have sole




<PAGE>   38






operational control over the transportation of gas on Bay Gas' system from the
Point of Delivery to the Point of Redelivery. For transportation service,
"Delivery" shall mean the act of causing gas to be transported to the Points of
Delivery, and "Redelivery" shall mean the transportation of gas from the Points
of Delivery to the Points of Redelivery.


                                       VI.

                          GENERAL TERMS AND CONDITIONS
                       FOR GAS STORAGE AND TRANSPORTATION

         Amended General Terms and Conditions to Bay Gas Storage Company, Ltd.'s
Storage and Transportation Service Agreements, dated December 22, 1998, are
incorporated by reference as part of this Statement of Conditions. Shipper's
failure to comply with the provisions in Section II, Nominations, Balancing And
Excess Deliveries, of such General Terms and Conditions shall relieve Bay Gas of
its obligation to perform services, and, if such failure to comply unreasonably
interferes, in Bay Gas' judgment, with Bay Gas' control over its system
facilities, then Bay Gas may, at its option, cease services and terminate any
related Service Agreements or other agreements, without limitation of Bay Gas'
rights or remedies at law or in equity.


                                      VII.

                           RIGHT TO TERMINATE SERVICES

         Bay Gas reserves the right to discontinue, on a non-discriminatory
basis, all services that subject Bay Gas to the non-discriminatory access
requirements of 18 C.F.R. Part 284, and any subsequent Commission Orders, Rules
or Regulations applicable to such services. Bay Gas may cancel the affected
Service Agreements at any time on ninety (90) days prior written notice to
Shippers if Bay Gas has no other reasonable options available that will allow
the continuation of such Service Agreements. Bay Gas shall be relieved of all
obligations and liabilities on the effective date of such


<PAGE>   39






notice of discontinuance and cancellation. Bay Gas additionally reserves the
right to terminate any interruptible Service Agreement if the Shipper either has
not executed the Service Agreement within thirty (30) days of receiving such
Agreement, or has failed to nominate service under such Agreement within one (1)
year after execution of the Agreement.


                                      VIII.

                      COMPLIANCE WITH LAW AND SURVIVABILITY

         If any part of this Statement of Conditions conflicts with, or
violates, any Commission or other Judicial, Governmental or Regulatory Body's
Orders, Rules or Regulations, such part shall be deemed void, but shall not
affect the remaining provisions of this Statement. Bay Gas shall not be liable
to any party with a Service Agreement subject to this Statement that loses
priority status or any other rights enumerated in this Statement because of the
issuance by the Commission or other Judicial, Governmental or Regulatory Body of
any Orders, Rules or Regulations affecting this Statement of Conditions.


                                       IX.

                     CHANGES TO THIS STATEMENT OF CONDITIONS

         Bay Gas reserves the right to add to, delete or modify the conditions
in this Statement without prior notice.


                                       X.

                      AUTHORITY OF STATEMENT OF CONDITIONS

         This Statement of Conditions, and the incorporated General Terms and
Conditions (see Section "VI." above) take precedence over conflicting language
in any of Bay Gas' Service Agreements or amendments thereto, unless such
language specifically states that it is an exception to this Statement, and then
only to the extent of such stated exception.

                    percent (2%) by volume of oxygen, and shall not contain more
                    than three percent (3%) by volume of carbon dioxide.

               d.   Have a heating value of not less than nine hundred fifty
                    (950) Btu's per cubic feet.

               e.   Have a temperature of not more than one hundred twenty
                    degrees Fahrenheit (120 F), nor less than forty degrees
                    Fahrenheit (40 F).

               f.   Shall be dehydrated and shall in no event have a water
                    content in excess of seven (7) pounds of water per million
                    (1,000,000) cubic feet of gas measured at a pressure base of
                    14.73 psi and at a temperature base of 60 degrees
                    Fahrenheit, as determined by dew point or other moisture
                    measuring equipment in general use in the industry.


                ARTICLE VIII - PROPERLY NOMINATED GAS; IMBALANCES

         8.1 Proper Nomination. Shipper must Properly Nominate any gas for which
Shipper requests Receipt and Delivery. "Properly Nominate" means that Shipper's
dispatcher shall send Bay Gas' dispatcher timely prior notice, sufficient to
meet the requirements of all pipelines, gatherers or distributors involved in
the Shipper gas delivery to the Point(s) of Receipt of the volumes of gas
Shipper desires to transport to the Point of Delivery. Such notice shall be at
least twenty-four (24) hours prior to the earliest regularly scheduled
nomination deadline of the pipelines/distributors delivering gas at the Point(s)
of Receipt for gas to be delivered commencing on the first day of a month and
one hour earlier than such deadline for any subsequent nomination. All gas
received and delivered hereunder shall be received and delivered in as nearly
equal daily and hourly quantities as operating conditions permit. Shipper
intraday or late nominations of gas hereunder will be accepted by Bay Gas on a
best efforts basis. If acceptance of Shipper's nomination would exceed the MDTQ,
or cause interruption of another shipper's scheduled service, then such
nomination will be accepted or rejected at Bay Gas' sole discretion.

         8.2 Imbalances at the Point of Delivery. Imbalances that take place at
the Point of Delivery shall be monitored by Bay Gas on a real-time basis, and
Bay Gas shall seek to correct such imbalances, first by requesting the
cooperation of the applicable interstate pipeline, and next by utilizing the
storage service Agreement in place between Bay Gas and Southern Company
Services, Inc., as the agent of Shipper (the "Storage Agreement"). Shipper will
notify Bay Gas of any change to its schedule that would create imbalances and
Bay Gas will in turn seek the cooperation of the applicable interstate pipeline.
To the extent that such

                                        4

<PAGE>   7





cooperation is not granted, or such cooperation is not granted in the amount
needed to avoid imbalances, Bay Gas shall utilize the Storage Agreement to
either inject or withdraw gas from storage.

         8.3 Seamless Transactions. Bay Gas agrees to take all actions
reasonably necessary to provide "Seamless Service" to Shipper under this
Agreement. As used in this Agreement the term "Seamless Service" means that the
nominations, scheduling, resolution of imbalances and any other procedures or
matters reasonably determined to effect service to Shipper via Bay Gas' service
under this Agreement shall be coordinated with the applicable interstate
pipeline company and implemented such that Shipper will, to the extent
reasonably possible, be relieved of any duplicative administrative activity that
might otherwise be necessary. To facilitate such Seamless Service, Shipper may,
subject to the interstate pipeline company's approval, assign the obligations
set forth in Section 8.1 ("Proper Nomination") above to the applicable
interstate pipeline company. Bay Gas agrees to use reasonable efforts to have
operational balancing agreements in place with Florida Gas Transmission and Koch
Gateway Pipeline Company in order to facilitate the provision of Seamless
Service.

         8.4      Imbalances at the Point(s) of Receipt.

              (a) If, during any month, Shipper receives an invoice from a
     supplier or transporter which includes imbalance charges, the Parties shall
     use their best efforts to promptly determine the validity, as well as the
     cause, of such imbalance charges. If the Parties determine that the
     imbalance charges were incurred as a result of Shipper's actions or
     inactions (which shall include, but not be limited to, Shipper's failure to
     accept quantities of gas equal to the nominated gas), then Shipper shall
     pay for such imbalance charges. If the Parties determine that the imbalance
     charges were incurred as a result of Bay Gas' actions or inactions, then
     Bay Gas shall pay for such imbalance charges or reimburse Shipper for such
     imbalance charges paid by Shipper.

              (b) Bay Gas may, at its sole discretion, choose to receive all or
     a portion of the gas nominated for receipt from Koch Gateway Pipeline's
     ("Koch") system for transportation hereunder at either the "Primary Koch
     Receipt Point" or the "Secondary Koch Receipt Point", or both, as listed on
     Exhibit "A". Shipper and Bay Gas agree that Bay Gas will communicate
     directly with Koch to facilitate such scheduling changes as may be needed.

              (c) At Koch's request, Bay Gas shall receive gas for transport
     hereunder at the Koch Secondary Receipt Point in amounts up to 25,000 MMBtu
     per day. Provided however that Bay Gas shall not be required to make such
     capacity available until Koch has fully utilized the capacity of its
     pipeline facilities between its mainline and the Bay Gas pipeline on behalf
     of Bay Gas or Bay Gas customers.



                            ARTICLE IX - MEASUREMENT

         9.1 Unit of Volume Measurement. The unit of volume for measurement of
gas Received and Delivered hereunder shall be one (1) cubic foot of gas at a
base temperature of sixty degrees Fahrenheit (60 F) and at an absolute pressure
of fourteen and seventy-three hundredths (14.73) pounds per square inch. All
fundamental constants, observations, records, and procedures involved in
determining and/or verifying the quantity and other characteristics of gas

                                        5

<PAGE>   8





delivered hereunder shall, unless otherwise specified herein, be in accordance
with the standards prescribed in Reports No. 3 and/or 7 of the American Gas
Association, as now and from time to time amended or supplemented. All
measurements of gas shall be determined by calculation into terms of such unit.
All quantities given herein, unless expressly stated otherwise, are in terms of
such unit. Notwithstanding the foregoing, it is agreed that, for all purposes,
the Btu content of the gas Received and Delivered hereunder shall be measured on
an "as delivered" basis rather than a fully saturated or "wet" basis.

         9.2 Facilities to be Constructed by Bay Gas. Bay Gas shall construct at
its expense, and own, maintain and operate the metering station and associated
facilities, including without limitation a gas chromatograph, pressure recorder,
gas measuring equipment, tie-in piping and (the "Meter Station"), and such other
necessary monitoring, odorization and recording equipment that must be installed
to provide accurate measurement and custody transfer, and to deliver gas at the
pressure required in Article III (the "Equipment"). The Meter Station and
Equipment (collectively, the "Facilities") will be located at a mutually
acceptable site either on the Plant site or at a location outside of the Plant.
If the facilities are located on Shipper's property, Shipper shall provide to
Bay Gas such easement or easements, in form reasonably acceptable to Bay Gas,
for the Facilities and for construction of pipelines, to the Point of Delivery.
Upon selection of the site, Shipper shall prepare a drawing reflecting the
location of the Facilities, and the drawing shall be attached hereto as Exhibit
"E". Bay Gas shall obtain all permits, licenses, authorizations, certificates
and other required governmental approvals necessary for the construction and
operation of the Facilities ("Governmental Approvals"). Shipper shall be
responsible for the construction and maintenance of its pipeline and any
associated equipment from the Point of Delivery into the Plant. Bay Gas shall
provide a signal or signals, including gas flow, pressure, and analysis data
from measurement equipment, such that the Shipper may monitor the gas flow.

         9.3 Timely Completion of Facilities. Time is of the essence in the
construction of the Facilities. Bay Gas agrees that the Facilities shall be
completed and ready for testing no later than August 15, 1999. If Bay Gas fails
to obtain required Governmental Approvals by July 1, 1999, then either Party may
terminate the Agreement without further liability or obligation to the other
Party.

         9.4 Measurement Accuracy. Bay Gas shall provide for verifying the
accuracy of the measuring equipment at least once in each one hundred eighty
(180) day period. If Shipper desires a special test of any measuring equipment,
it will promptly notify Bay Gas and the parties shall then cooperate to secure a
prompt verification of the accuracy of such equipment. The expenses of any such
special test, if requested by Shipper, shall be borne by Shipper if the
measuring equipment tested is found to be accurate within the limits of plus or
minus two percent (2%) of error. For the purposes of measurement and meter
calibration, the atmospheric pressure shall be assumed to be fourteen and
seventy-three hundredth (14.73) pounds per square inch, irrespective of
variations in natural atmospheric pressure from time to time. Bay Gas shall
notify Shipper at least one (1) business day prior to conducting any test of any
measuring equipment. Shipper and Bay Gas, upon request, shall have the right to
be present at any test of any measuring equipment.


                                        6

<PAGE>   9





         9.5 Measurement Corrections. If upon any test the metering equipment is
found to be inaccurate, in the aggregate, by two percent (2%) or more, either
plus or minus, registration thereof and any payment based upon such registration
shall be corrected at the rate of such inaccuracy for any period of inaccuracy
which is definitely known or agreed upon, or if not known or agreed upon, then
for a period extending back one-half (1/2) of the time elapsed since the day of
the last calibration,. Following any test, any metering equipment found to be
inaccurate to any degree shall be adjusted immediately to measure accurately;
however, if any inaccuracy is less than two percent (2%), all prior readings and
measurements shall be deemed to be accurate and no adjustments to any prior
reading shall be made. If, for any reason, any meter is out of service or out of
repair so that the quantity of gas delivered through such meter cannot be
ascertained or computed from the readings thereof, the quantity of gas so
delivered during such period shall be estimated and agreed upon by the parties
hereto upon the basis of the best available data, using the first of the
following methods which is feasible:

               a.   by using the registration of any check measuring equipment,
                    if installed and registering accurately;

               b.   by correcting the error if the percentage of error is
                    ascertainable by calibration, test, or mathematical
                    calculation; or

               c.   by estimating the quantity of gas deliveries by deliveries
                    during preceding periods under similar conditions when the
                    meter was registering accurately.

         9.6 Pressure & Temperature Correction. The measurement hereunder shall
be corrected for deviation from Boyle's Law at the pressure and temperature
under which gas is delivered hereunder.


                        ARTICLE X - BILLINGS AND PAYMENTS

         10.1 Statement Rendered. By the tenth (10th) day of each month, Bay Gas
shall render to Shipper a statement for the preceding month properly identifying
the applicable Point(s) of Receipt and Point of Delivery and showing the total
quantity of gas received from and delivered hereunder.

         10.2 Payment. Subject to Section 10.3 below, Shipper shall pay Bay Gas
the full amount reflected on the statements rendered at the address stated in
Section 15.1 on or before the twentieth (20) day of each calendar month. If the
twentieth day shall fall upon a weekend or legal holiday, then such payment may
be made on the first regular business day subsequent to such twentieth day. In
the event that Shipper fails to pay such amounts when due, interest shall accrue
on all unpaid amounts from the date due until paid at a rate of interest equal
to the lesser of: (i) the rate of interest quoted as the "prime rate" of Bay
Gas' bank to its largest and most credit-worthy commercial customers, plus 2%;
or (ii) the highest legal rate of interest allowed by law (the "Interest Rate").

         10.3 Corrections. In the event an error is discovered in the amount
billed in any statement rendered by Bay Gas, such error shall be adjusted within
thirty (30) days of the discovery of the error. In the event a dispute arises

                                        7

<PAGE>   10





as to the amount payable in any statement rendered, Shipper shall pay the
undisputed amount, and shall notify Bay Gas of the disputed amount and the
reasons for the dispute at the time payment is due. Bay Gas shall not suspend
delivery of gas as a result of Shipper's failure to pay the disputed amount. The
parties agree to work in good faith to resolve the subject dispute in a timely
fashion. The Parties are not obligated to pursue amicable resolution for more
than sixty (60) days, then the matter may be submitted to arbitration. If it is
finally determined that Shipper has underpaid the amount actually due, Shipper
shall remit any amount due, with interest at the Interest Rate, within ten (10)
days. If it is determined that Shipper has overpaid the amount actually due, Bay
Gas shall remit any refund, with interest at the Interest Rate, within ten (10)
days. All statements shall be considered final, and any and all objections
thereto are deemed waived, unless made in writing within twenty-four (24) months
of Shipper's receipt thereof.


                               ARTICLE XI - TAXES

         11.1 Tax Changes. Shipper agrees to pay to Bay Gas, by way of
reimbursement, within ten (10) days of receipt of an invoice for same, all taxes
levied or imposed upon Bay Gas after the date hereof; and any increases in
existing taxes which may be made effective after the date hereof, with respect
to the transport of gas hereunder. Bay Gas agrees to pass through to Shipper in
its monthly billings any savings resulting from decreases in existing taxes,
which may be made effective after the date hereof, with respect to the transport
of gas hereunder. In the event that any additional taxes or increases in taxes
are imposed and, should Bay Gas elect not to challenge the same, then Shipper
shall be subrogated to Bay Gas' rights to challenge the same. In no event shall
Shipper be required to pay any tax in a greater amount than its pro-rata share.

         11.2 Tax Definition. The term "taxes" as used in Section 11.1 shall
mean all taxes which are now in existence or which may in the future be levied
upon Bay Gas, or its facilities or the transportation of gas hereunder (other
than ad valorem, capital stock, income or excess profit taxes, or general
franchise taxes imposed on corporations on account of their corporate existence
or on their right to do business within the state as a foreign corporation and
similar taxes), including, but not limited to, gross receipts tax, street and
alley rental tax, licenses, fees and any other taxes, charges or fees of any
kind levied, assessed or made by any governmental authority on the act, right or
privilege of transporting, handling or delivering gas or using Bay Gas'
pipeline, which is measured by the volume, heating value, value of the gas, or
any fee in respect to the gas or the transportation or other handling thereof.


                         ARTICLE XII - REGULATORY BODIES

         12.1 APSC Approval. This Contract is subject to the approval of the
Alabama Public Service Commission.

         12.2 General Services Administration Regulation. Bay Gas agrees to
comply with the additional provisions attached hereto as Exhibit "D" and made a
part hereof.

                ARTICLE XIII - RIGHT TO DELIVER AND RISK OF LOSS

         13.1 Right to Deliver. Shipper warrants for itself, its successors and
assigns, that it will have at the time of delivery of gas hereunder the valid
right to deliver such gas hereunder. Shipper warrants for itself, its successors
and assigns, that the gas it delivers hereunder shall be free and clear of all
liens, encumbrances, or claims as against Shipper and that it will indemnify Bay
Gas and save it harmless from all claims, suits, actions, damages, costs and
expenses arising directly or indirectly from or with respect to the right to
deliver gas tendered to Bay Gas hereunder.

         13.2 No Encumbrance on Delivered Gas. Bay Gas covenants that it shall
neither cause nor allow any cloud or encumbrance of any nature to arise by,
through or under Bay Gas with respect to the title of any gas delivered to Bay
Gas, and agrees to deliver such gas pursuant to this Contract free from all
liens and adverse claims arising by, through or under Bay Gas, and that it will
indemnify, protect, and save Shipper harmless from all claims, suits, actions,
damages, costs and expenses arising directly or indirectly from the same.

         13.3 Hold Harmless.

               (a) Bay Gas shall protect, defend, indemnify, and hold harmless
     Shipper, its officers, directors, agents and/or employees from and against
     all claims, demands, losses, damages, suits and expenses relating to death
     of and/or injury to persons and/or damage to property (unless due to the
     sole negligence of Shipper) arising out of, or resulting from, the
     transportation of natural gas from the Point of Receipt to the Point of
     Delivery pursuant to the terms and conditions of this Agreement.

              (b) Shipper shall protect, defend, indemnify, and hold harmless
     Bay Gas, its officers, directors, agents and/or employees from and against
     any claims, demands, losses, damages, suits and expenses relating to death
     of and/or injury to persons, and/or damage to property (unless due to the
     sole negligence of Bay Gas) resulting from, the transportation of natural
     gas by Shipper or its agents to the Point of Receipt and from the Point of
     Delivery to and through the facilities of Shipper.

         13.4 Hold Harmless - Gas Quality. Each party hereto recognizes that the
quality of gas redelivered by Bay Gas is of the utmost importance. The parties
further recognize that due to the volumes of gas transported hereunder the
quality of the natural gas redelivered hereunder will be greatly impacted by the
quality of gas received at the Point of Receipt. Accordingly, in the event Bay
Gas accepts for delivery gas which meets the quality specifications specified in
Article VII, but redelivers gas to Shipper which does not meet those
specifications ("non-conforming gas") and such non-conforming gas causes damage
to the property of Shipper, Bay Gas shall be responsible for such property
damage. However, if the gas delivered to the Point of Receipt by Shipper does
not meet the quality specifications specified in Article VII of this Agreement,
then Bay Gas shall not be responsible for any damage to the property of the
Shipper as a result of the redelivery by it of such gas.

         13.5 Shipper's Equipment. Shipper shall install equipment at its
facilities to remove liquids which may be present in the natural gas stream. The
Parties hereto agree that Shipper shall be responsible for any property damage
that may result from the failure of such equipment.

                      ARTICLE XIV - DEFAULT AND TERMINATION

         14.1 Failure to Perform. If either Party hereto shall fail to perform
any of the covenants or obligations imposed upon it by virtue of this Contract
(except where such failure is provided for under any of the provisions hereof),
then in such event the other Party may, at its option, terminate this Contract
by proceeding as follows: the Party not in default shall provide a written
notice to be served upon the Party in default, stating specifically the cause
for terminating this Contract and declaring it to be the intention of the Party
giving the notice to terminate the same; whereupon, the Party in default shall
have thirty (30) days after receipt of the aforesaid notice in which to remedy
or remove the cause or causes of default stated in the notice of termination and
if, within said period of thirty (30) days, the Party in default does so remedy
and/or remove such cause or causes, and fully indemnifies the Party not in
breach for the direct actual damages of the Party which are associated with such
default, then such notice shall be nullified and this Contract shall continue in
full force and effect. In the event the Party in default does not so remedy
and/or remove the cause or causes of default, or does not fully indemnify the
Party giving the notice for such Party's actual damages as a result of such
breach within said period of thirty (30) days, then this Contract shall
terminate from and after the expiration of said period; provided, however, that
if such default is remedied but no indemnification therefor has been made due to
a bona fide dispute between the parties as to the amount thereof, then this
Contract shall not terminate, but the Party not in default shall have the right
to seek recovery of its direct damages as provided by law. Any termination for
breach of this Contract shall be carried out strictly in accordance with this
section.

         14.2 Right to Collect Amount Due. Any cancellation of this Contract
shall be without prejudice to the right of the Party not in default to collect
any amounts then due it and without waiver of any other remedy to which the
Party not in default may be entitled.

         14.3 Bay Gas Right to Terminate. This Agreement may be terminated by
Bay Gas if Bay Gas does not obtain authorization from the appropriate regulatory
authorities to provide service under this Agreement which is acceptable to Bay
Gas, or Bay Gas does not obtain Government Approvals which are acceptable to Bay
Gas in its sole, but reasonably exercised discretion and which Bay Gas
determines are needed to provide service to Shipper at the Plant. Provided,
however, that Bay Gas agrees to give Shipper notice of any unacceptable terms
and conditions within ten (10) days after issuance.

         14.4     Shipper Right to Terminate.

               (a) Shipper may terminate this Agreement if Bay Gas fails to
     deliver nominated gas at the Point of Delivery for a period of forty-five
     (45) consecutive days for any reason, including the occurrence of force
     majeure.

               (b) In the event Bay Gas, on an ongoing basis, fails to deliver
     gas meeting the gas specifications or pressure required under this
     Agreement, the Parties will endeavor to identify and correct the quality
     and/or pressure problem being incurred. In the event a satisfactory
     solution is not obtained

                                       10

<PAGE>   13





     within forty-five (45) days of the Shipper notifying Bay Gas of the
     problem, Shipper may terminate this Agreement.

                           ARTICLE XVI - FORCE MAJEURE

         16.1 In the event Bay Gas is rendered unable, wholly or in part, by
reason of force majeure to carry out its obligations under this Agreement, it is
agreed that Bay Gas shall give notice and reasonably full particulars of such
force majeure, in writing by either mail, hand delivery, or facsimile, to
Shipper within a reasonable time after the occurrence of the cause relied on,
and the obligations of Bay Gas, so far as they are affected by such force
majeure, shall be suspended during the continuance of any inability so caused,
but for no longer period, and such cause shall, so far as possible, be remedied
with all reasonable dispatch.

         16.2 In the event Shipper is rendered unable, wholly or in part, by
reason of force majeure to carry out its obligations under this Agreement (other
than the obligation to make payment of amounts due hereunder), which obligations
shall not be affected by events of force majeure), it is agreed that Shipper
shall give notice and reasonably full particulars of such force majeure, in
writing by either mail, hand delivery, or facsimile, to Bay Gas within a
reasonable time after the occurrence of the cause relied on, and the obligations
of Shipper, so far as they are affected by such force majeure, shall be
suspended during the continuance of any inability so caused, but for no longer
period, and such cause shall, so far as possible, be remedied with all
reasonable dispatch.

         16.3 The term, "force majeure," as employed herein shall mean acts of
God; strikes, lockouts, or other industrial disturbances; conditions arising
from a change in governmental laws, orders, rules or regulations; acts of public
enemy; wars; blockades; insurrections; riots; epidemics; landslides; lightning;
earthquakes; fires; storms; floods; washouts; arrests and restraints of
governments and people; civil disturbances; explosions; breakage or accident to
machinery or lines of pipe; the necessity for making repairs, tests or
alterations to machinery or lines of pipe; freezing of wells or lines of pipe;
partial or entire failure of wells, processing or gasification and gas
manufacturing facilities; and any other causes, whether of the kind herein

                                       12

enumerated or otherwise, not within the control of the Party claiming
suspension, and which by the exercise of due diligence, such Party is unable to
prevent or overcome. Such term shall likewise include: (a) those instances where
either Bay Gas or Shipper is required to obtain servitudes, rights-of-way,
grants, permits or licenses to enable such Party to fulfill its obligations
under this Agreement; and such Party is unable to acquire, at reasonable costs,
and after the exercise of reasonable diligence, such servitudes, rights-of-way,
grants, permits or licenses, and (b) those instances where either Bay Gas or
Shipper is required to furnish materials and supplies for the purpose of
constructing or maintaining facilities or is required to secure permits or
permissions from any governmental agency to enable such Party to fulfill its
obligations under this Agreement and such Party is unable to acquire, or is
delayed in acquiring, at reasonable costs, and after the exercise of reasonable
diligence, such materials and supplies, permits and permissions. Force majeure
shall not include failure of gas supply due to pricing considerations.

         16.4 It is understood and agreed that the settlement of strikes or
lockouts shall be entirely within the discretion of the Party having the
difficulty, and that the above requirement that any force majeure shall be
remedied with all reasonable dispatch shall not require the settlement of
strikes or lockouts by acceding to the demands of the opposing Party when such
course is inadvisable in the discretion of the Party having the difficulty.

A.   Nominations. Shipper shall furnish to Bay Gas a nomination on a form
     acceptable to Bay Gas. All quantities shall be expressed in MMBtu per Day
     and shall separately state Points of Receipt, Points of Delivery or Points
     of Redelivery.

     1.   Shipper must deliver the nominations to Bay Gas by 11:30 A.M. Central


                                        2

<PAGE>   22






          ClockTime the working day prior to gas flow. Shipper may submit
          nominations after such deadline up to 1:00 P.M. Central Clock Time for
          the upcoming gas day. However, if acceptance of Shipper's nomination
          submitted between 11:30 and 1:00 P.M. Central Clock Time would exceed
          Shipper's Maximum Daily Injection Quantity or Maximum Daily Withdrawal
          Quantity or Maximum Storage Quantity or Maximum Daily Transportation
          Quantity, or would cause interruption of another shipper's scheduled
          service, then such nomination will be accepted or rejected by Bay Gas
          at Bay Gas' sole discretion.

     2.   Shipper may submit, and Bay Gas will accept, nominations after 1:00
          P.M. for the upcoming gas day or during the current gas day on a best
          efforts basis. If acceptance of Shipper's nomination for service would
          exceed Shipper's Maximum Daily Injection Quantity or Maximum Daily
          Withdrawal Quantity or Maximum Storage Quantity or Maximum Daily
          Transportation Quantity, or would cause interruption of another
          shipper's scheduled service, then such nomination will be accepted or
          rejected at Bay Gas' sole discretion.

     3.   Nominations made in accordance with this Section II A shall not become
          effective until Bay Gas has confirmed the nominated storage receipts
          (injections) and deliveries (withdrawals), or transportation
          deliveries and redeliveries, with upstream and downstream parties.
          Shipper shall designate the appropriate person(s) with authority to
          confirm nominations and to resolve allocation issues on a
          24-hour-basis.

     4.   The parties intend that the volumes of gas received or delivered or
          redelivered will be equal to the confirmed nominations. To the extent
          that gas quantities actually received or delivered or redelivered may
          be greater than or less than the confirmed nominations, the parties
          intend that such variance will be treated in accordance with an
          Accounting Allocation Agreement entered into between the parties.

     5.   Bay Gas shall not be obligated, during any hour, to receive or to
          deliver or to redeliver a total volume of gas in excess of one
          twenty-fourth (1/24th) of the lesser of (a) Shipper's aggregate
          Maximum Daily Injection Quantity or Maximum Daily Withdrawal Quantity,
          or Maximum Daily Transportation Quantity or (b) Shipper's accepted
          nomination volumes. The parties intend that from time to time Shipper
          and Bay Gas may mutually agree to a flow rate above or below a uniform
          hourly rate.

B.   Balancing. Bay Gas will accept for storage injection or deliver for
     withdrawal, or for transportation delivery and redelivery, on a daily
     basis, volumes thermally equivalent to volumes nominated and scheduled,
     less appropriate compressor fuel and lost-and-unaccounted-for gas
     (collectively called "Company Use") charges, unless otherwise mutually
     agreed to in writing. All imbalances between actual and nominated


                                        3

<PAGE>   23






     injection volumes or withdrawal volumes, or between delivery volumes and
     redelivery volumes, shall be treated as imbalance under, and received in
     accordance with, the Storage or Transportation Service Agreement(s) under
     which the gas in question is delivered to or from the storage or
     transportation facilities. Gas delivered to Bay Gas for withdrawal or
     redelivery hereunder on each day shall be at constant uniform rates as
     practicable throughout such day.

     1.   If Shipper is advised by any upstream third party of the need to
          reduce or suspend deliveries of gas scheduled for delivery to or from
          storage, or for transportation delivery and redelivery, Shipper shall
          immediately notify Bay Gas orally, and shall confirm such notification
          in writing, of such reduction or suspension.

     2.   Nothing in this Section II B shall limit Bay Gas' right to take action
          as may be required to adjust injections or withdrawals of gas,
          including suspending storage services or to adjust deliveries and
          redeliveries, including suspending transportation services, in order
          to alleviate conditions that threaten the integrity of its system.

     3.   In the absence of an executed Accounting Allocation Agreement between
          Shipper and Bay Gas as described in Section II A. 4, balancing
          procedures shall be as specified in this Section II B. If an
          Accounting Allocation Agreement is in effect between Shipper and Bay
          Gas, such Agreement shall take precedence over the provisions
          specified in this Section II B.

     4.   If there is more than one supply source (whether at a single or at
          multiple Points of Receipt or Delivery) nominated to be received for
          Storage or Transportation, the nomination will identify how and which
          supply source(s) should be allocated by means of a Receipt
          Pre-Determined Allocation ("RPDA") specified in the nomination. In
          accounting for the volumes delivered or redelivered by Bay Gas, in
          circumstances where multiple services are provided at any Point of
          Delivery or Redelivery, the sequence of volumes delivered shall be
          determined by the Delivery Pre-Determined Allocation ("DPDA")
          specified by Shipper in its most recent nomination. The nomination
          will identify which supply source(s) should be allocated in the event
          gas is not or cannot be delivered or redelivered as nominated.

     5.   To the extent feasible, all volumes received by or delivered to Bay
          Gas at a Point of Receipt or Delivery shall be allocated in accordance
          with the confirmed nominations for that point. In the event the actual
          volumes received by Bay Gas do not equal the confirmed nominations for
          that point, any underage or overage will be allocated as follows:

               (a)  First, in accordance with the effective RPDAs submitted by
                    Shipper (or Shipper's suppliers). Shipper agrees that such
                    an allocation is binding on Shipper.


                                        4

<PAGE>   24







               (b)  Then, if there is no effective RPDA, pro rata to the extent
                    applicable based on confirmed nominations, as applicable.
                    Shipper agrees that such an allocation is binding on
                    Shipper.

     6.   To the extent feasible, all volumes delivered or redelivered by Bay
          Gas at a Point of Delivery or Redelivery shall be allocated in
          accordance with the confirmed nominations for that point. In the event
          the actual volumes delivered by Bay Gas do not equal the confirmed
          nominations for that point, any underage or overage will be allocated
          as follows:

               (a)  First, in accordance with the effective DPDAs submitted by
                    Shipper (or Shipper's suppliers). Shipper agrees that such
                    an allocation is binding on Shipper.

               (b)  Then, if there is no effective DPDA, pro rata to the extent
                    applicable based on confirmed nominations, as applicable.
                    Shipper agrees that such an allocation is binding on
                    Shipper.

     7.   Each Shipper shall be responsible for ensuring that its suppliers
          submit Pre-Determined Allocations ("PDAs", which include RPDAs or
          DPDAs) as provided herein using a form acceptable to Bay Gas. Unless
          otherwise agreed, all PDAs must be submitted to Bay Gas via facsimile
          or other agreed upon electronic means on or before the date the PDA is
          to be effective. Such PDA shall specify how any underage or overage
          from the confirmed nominated volumes should be allocated among the
          entities listed on the PDA. Bay Gas shall acknowledge receipt and
          acceptance of the PDA by returning acknowledgment of the PDA to
          Shipper via mutually agreeable means. Bay Gas acceptance is contingent
          on Bay Gas being able to administer the allocation submitted by the
          Shipper.

     8.   To the extent that actual injections or actual withdrawals, or actual
          deliveries or actual redeliveries, for each Shipper do not exactly
          match confirmed nominations for any day, Bay Gas will attempt to
          balance any such differences among Bay Gas and the upstream or
          downstream entities, without impacting Shipper, whenever possible. If
          an upstream or downstream entity requires a Balancing Agreement for
          which any fee is required, Shipper agrees to reimburse Bay Gas for any
          incurred expenses.


C.   Storage Balance Reconciliation. To the extent Shipper and Bay Gas agree, in
     writing, that imbalances may be accounted for under the Shipper's Storage
     Service Agreement, and to the extent Shipper has sufficient storage
     capacity, Bay Gas will issue a formal storage balance notice to Shipper by
     the 20th of the month following the injection/withdrawal month ("the Notice
     Month"), reflecting the effect of Shipper's storage balance or any
     imbalance. Shipper understands and


                                        5

<PAGE>   25






     agrees to contact or cause to be contacted, the parties that deliver
     injection volumes to Bay Gas, or receive withdrawal volumes from Bay Gas,
     for the Shipper's account to confirm any imbalance.

     Following the termination of the Storage Service Agreement, Shipper shall
     be required to either (a) transfer title to any volumes of gas in storage
     to a third party with whom Bay Gas has a Storage Service Agreement, with
     such transfer to be subject to any injection conditions or charges
     applicable to such third party, or (b) withdraw such volumes from storage
     within a sixty (60) day balancing period after the determination by Bay Gas
     that any such volumes exist, or within such longer period of time mutually
     agreed upon by Shipper and Bay Gas. Shipper agrees that at the end of the
     above sixty (60) day balancing period, Bay Gas will, for any storage
     volumes not withdrawn, take title to such gas and such title is to pass
     automatically without cost to Bay Gas.

D.   Excess Deliveries. In the event that Shipper, from time to time, desires to
     have injected into or withdrawn from storage, or to have transported, or to
     have transported, quantities of gas in excess of the Maximum Daily
     Injection Quantity or Maximum Daily Withdrawal Quantity, or Maximum Daily
     Transportation Quantity, respectively, which Bay Gas is obligated to accept
     or deliver or redeliver under storage or transportation arrangements for
     Shipper on any day under a Storage or Transportation Service Agreement,
     Shipper may request injection or withdrawal or transportation of such
     excess gas, and Bay Gas in its sole discretion may accept or deliver or
     redeliver all or any part of such gas subject to the restrictions of these
     General Terms and Conditions.

                                  SECTION III.
                           Construction of Facilities

         Under no circumstances shall Bay Gas be obligated to construct or add
facilities to receive or deliver or redeliver gas under a Storage or
Transportation Service Agreement, or to increase the capacity of Bay Gas'
pipeline system or storage or transportation facilities. Upon Shipper's written
request to evaluate connections of new facilities, Bay Gas will prepare and
submit to Shipper a construction cost estimate. All new or additional facilities
that may be required for the delivery of acceptable gas to Bay Gas, or for the
delivery or redelivery of gas to the receiving party or parties will be
constructed, maintained, owned and operated by Bay Gas, except as may otherwise
be expressly agreed in writing. The design and installation of all facilities
shall be in accordance with the specifications then used by Bay Gas for like or
similar facilities. Shipper shall bear the cost of all such new connections,
unless otherwise mutually agreed.


                                   SECTION IV.
                                 Rate Adjustment

A.   Rates charged for services shall be negotiated between Bay Gas and Shipper.
     Bay Gas reserves the right to seek authorization from the


                                        6

<PAGE>   26






     Federal Energy Regulatory Commission ("FERC") or other appropriate agency
     to increase, decrease or restructure the rates (including market based
     rates), and Company Use charges in effect at any time as may be found
     necessary to assure Bay Gas' right to charge and collect fair and equitable
     rates within the meaning of Section 311 (a)(2) of the Natural Gas Policy
     Act of 1978 ("NGPA") and the FERC's rules and regulations thereunder.
     Nothing herein contained shall be construed to deny any Shipper any rights
     which it may have under FERC rules and regulations, including the right to
     participate fully in rate proceedings by intervention or otherwise to
     contest changes in rates and Company Use charges in whole or part. In
     addition to the rates above, Shipper shall pay in advance all applicable
     state and federal filing, reporting and application fees incurred by Bay
     Gas for providing such services.

B.   Bay Gas may at any time provide firm or interruptible storage services at
     different rates from the market based rates approved by the FERC for Bay
     Gas' NGPA Section 311(a)(2) services. Nothing herein shall obligate or
     require, or be construed to obligate or require, Bay Gas to offer or
     continue such different rates.


                                   SECTION V.
                             Regulatory Requirements

         Bay Gas' interstate services shall be in accordance with and subject to
the requirements of Section 311(a)(2) of the NGPA and the rules and regulations
of the FERC thereunder. Bay Gas' intrastate services shall be in accordance with
and subject to the laws, rules and regulations of the State of Alabama.

         Bay Gas agrees to proceed with reasonable diligence during the term of
the Storage or Transportation Service Agreement with the filing for and
prosecution of any authorizations as may be required for the storage or
transportation of the gas hereunder or the rate(s) charged therefor. Bay Gas
reserves the right to pursue any necessary regulatory filings with FERC and any
other governmental or regulatory body having jurisdiction in such matter as it
deems to be in its best interest, including the right to file whatever pleadings
and motions it deems desirable. In the event Bay Gas has obtained such necessary
regulatory authorization, but the terms and conditions are significantly
different than those terms originally filed with the regulatory agency, or in
the event FERC rejects or modifies Bay Gas' Statement of Conditions for NGPA
Section 311(a)(2) Gas Storage and Transportation Services, as same may be
amended by Bay Gas from time to time, Bay Gas shall pursue other reasonable
options to continue providing such services or, at Bay Gas' option, shall
terminate such services as provided in Article VII, Right to Terminate Services,
of Bay Gas' Statement of Conditions.




                                   SECTION VI.
                                    Pressures


                                        7

<PAGE>   27







         Bay Gas shall operate its storage facilities at pressures which will
accommodate the withdrawal of gas in accordance with Bay Gas' outstanding firm
service storage commitments. Bay Gas shall operate its transportation facilities
at pressures which will accommodate the redelivery of gas in accordance with Bay
Gas' outstanding firm service transportation commitments. Shipper shall be
obligated to deliver gas for injection or for transportation, at a pressure
sufficient for Bay Gas to transport such gas to and inject into its storage
facility, or to transport such gas for redelivery, recognizing that the amount
of such pressure will vary based on the operation of the Bay Gas pipeline.


                                  SECTION VII.
                                   Measurement

A.   The gas received for injection or delivered for withdrawal at the storage
     facilities, or delivered or redelivered at the transportation facilities,
     shall be measured with meters constructed and installed, and whose
     computations of volume are made, in accordance with the provisions of
     ANSI-API 2530-AGA-3, latest revision as adopted by Bay Gas.

B.   The temperature of the gas shall be determined by a recording thermometer
     so installed that it will record the temperature of the gas flowing through
     the meters. The average of the record to the nearest one degree (1 degree)
     Fahrenheit, obtained while gas is being delivered, shall be the applicable
     flowing gas temperature for the period under consideration. For all
     measurement of gas required in this Section, the BTU content per cubic foot
     shall be determined for a cubic foot of gas at a temperature of sixty
     degrees (60 degrees) Fahrenheit, at an absolute pressure of fourteen and
     seventy-three hundredths (14.73) pounds per square inch on a dry basis.

C.   The BTU, specific gravity, carbon dioxide, and nitrogen content of the gas
     shall be determined by the use of an on-line chromatograph or by a
     chromatographic analysis of the gas obtained by a continuous sample or spot
     sampling method. The results of any sample taken with an on-line
     chromatograph shall be applied to the month in which the sample was taken.

D.   Adjustment for the effect of supercompressibility shall be made according
     to the provisions of the latest version of either NX-19 or AGA Committee
     Report No. 8, as required by Paragraph A. of this Section and as adopted by
     Bay Gas, for the average conditions of pressure, flowing temperature, and
     specific gravity at which the gas was measured during the period under
     consideration and with the proportionate values of carbon dioxide and
     nitrogen in the gas delivered included in the computation of the applicable
     supercompressibility factors.

E.   If at any time during the term hereof a new method or technique is
     developed with respect to gas measurement or the determination of the
     factors used in such gas measurement, such new method or technique may


                                        8

<PAGE>   28






     be substituted for the gas measurement set forth in this Section on the
     date such method or technique is adopted by Bay Gas.



                                  SECTION VIII.
                         Measuring Equipment and Testing

A.   General. The construction, ownership, operation and maintenance of any
     measuring equipment necessary to accomplish the storage receipt of gas for
     injection by Bay Gas for the account of Shipper and the delivery of gas
     withdrawn by Bay Gas for the account of Shipper, or the transportation
     delivery of gas to Bay Gas for the account of Shipper and the redelivery of
     gas by Bay Gas for the account of shipper shall be the responsibility of
     Bay Gas. Shipper shall at all reasonable times have access to the premises
     of Bay Gas for inspections, insofar as such premises are connected with any
     matter or thing covered hereby. The operation of measuring equipment and
     changing of charts shall be done only by the employees or agents of Bay
     Gas.

B.   Testing and Repair of Equipment.

     1.   Bay Gas shall keep its own measuring equipment accurate and in repair,
          making periodic tests to verify the condition of meter tubes, orifice
          plate, and chart recorder or flow computer. Bay Gas agrees to give
          Shipper(s) seven (7) calendar days notice prior to such tests of the
          measuring equipment so that, if desired, Shipper(s) may have its
          representative present. Shipper(s) shall have the right to challenge
          the accuracy of Bay Gas' equipment, and when challenged, the equipment
          shall be tested, calibrated and, if required, repaired by Bay Gas, the
          cost of such special test to be borne by Bay Gas if the percentage of
          the inaccuracy is found to be more than two percent (2%), but if the
          percentage of inaccuracy is found to be two percent (2%) or less, the
          cost of such special test shall be borne by the Shipper(s). If upon
          any test the percentage of inaccuracy is found to be in excess of two
          percent (2%), registrations thereof shall be corrected for a period
          extending back to the time such inaccuracy occurred, if such time is
          ascertainable, and if not ascertainable, then back one-half (1/2) of
          the time elapsed since the last date of calibration. Any measuring
          equipment found to be measuring inaccurately by one percent (1%) or
          more shall be adjusted at once to read accurately.

     2.   If, for any reason, the meter(s) are out of service or out of repair
          so that the amount of gas received or delivered cannot be ascertained
          or computed from the readings thereof, the gas received or delivered
          during the period such meter(s) are out of service or out of repair
          shall be estimated and agreed upon by the parties hereto by the use of
          the first applicable of the following methods:



                                        9

<PAGE>   29






               (a)  By comparative utilization of any like check measuring
                    equipment if such check measuring equipment can be proven
                    and verified to be measuring accurately; or

               (b)  By computing the error if the percentage of error is
                    ascertainable by calibration, test or mathematical
                    calculation; or

               (c)  By estimating the quantity received or delivered by
                    reference to actual receipts or deliveries during preceding
                    periods under similar conditions when Bay Gas' measuring
                    equipment was registering accurately.

C.   Inspection of Charts and Records. The charts and records from the measuring
     equipment shall remain the property of Bay Gas and shall be kept on file
     for a period of time not less than two (2) years from the end of the
     calendar year in which the charts and records were generated or prepared.
     At any time within such period, upon written request by Shipper, records or
     charts from the measuring equipment, together with calculations therefrom,
     will be submitted for Shipper's inspection and verification subject to
     return to Bay Gas within thirty (30) days from receipt thereof. All
     inquiries regarding this Section VIII, including but not limited to,
     measurement charts, records or audits of charts and records, shall be
     directed to Bay Gas.



                                   SECTION IX.
                                     Quality

         The gas delivered by either party to the other hereunder shall meet or
exceed the quality specifications of the transporting pipeline which receives or
delivers such gas to the other party hereunder.


                                   SECTION X.
                     Billing, Accounting, Taxes and Reports

A.   Billings and Payments.

     1.   For the purpose of billing and accounting for the gas delivered
          hereunder, the day shall begin at 9:00 a.m. Central Clock Time and
          extend to 9:00 a.m. the following day, and the month (hereinafter
          called "billing month") shall begin at 9:00 a.m. Central Clock Time on
          the first (1st) day of the calendar month and extend to 9:00 a.m. on
          the first (1st) day of the following calendar month.

     2.   Bay Gas shall render to its Shippers, by mail or facsimile, on or
          before the first (1st) day of each month an invoice setting forth the
          demand charges as applicable. Within ten (10) days from the date of
          the invoice, Shipper agrees to make payment to Bay Gas by wire
          transfer to the AmSouth Bank of Alabama, crediting Bay Gas'


                                       10

<PAGE>   30






          account number 83794638 for such firm demand charges for the account
          of Shipper at the Delivery Point(s) during the current month.

     3.   On or before the fifteenth (15th) day of each calendar month, Bay Gas
          shall render or cause to be rendered, by mail or facsimile, to all
          Shippers an invoice of the amount due for the preceding month setting
          forth the total quantity of gas (1) received by Bay Gas from Shipper
          for injection into the storage facilities, or delivered by shipper to
          Bay Gas for transportation; (2) delivered by Bay Gas to Shipper for
          withdrawal from the storage facilities, or redelivered by Bay Gas to
          Shipper after transportation; (3) gas balance at the beginning and end
          of the injection/withdrawal, or transportation, month and (4) the
          rates and charges for storage or transportation services hereunder
          during such billing month. Billings for volumes transported shall be
          determined on a dry basis.

     4.   Within ten (10) days from the date of the fifteenth (15th) day
          invoice, Shipper shall pay Bay Gas the amount due for all gas
          injected, withdrawn or stored, or transported, by Bay Gas for the
          account of Shipper during the injection/withdrawal, or transportation,
          month. Payments to Bay Gas shall be made either by wire transfer to
          the AmSouth Bank of Alabama, crediting Bay Gas' account number
          83794638, or by check such that funds are available to Bay Gas on or
          before the tenth (10th) day after the date of the invoice. If
          rendering of an invoice by Bay Gas is delayed after the fifteenth day
          of the month, then the time of payment shall be extended accordingly
          unless Shipper is responsible for such delay.

B.   Late Payment. In the event Shipper shall fail to pay any amount due Bay Gas
     when the same is due, Bay Gas shall have the option of accruing interest at
     a varying rate per annum (based on a year of 365 or 366 days, as the case
     may be) which shall be one hundred fifteen percent (115%) of the prime rate
     charged by the AmSouth Bank of Alabama to its largest and most creditworthy
     commercial borrowers on ninety (90) day commercial loans (but in no event
     greater than the maximum rate of interest permitted by law) with
     adjustments in such rate, for any period during which the same shall be
     overdue, such interest to be paid when the amount past due is paid. Shipper
     shall not be required to pay interest on any amount billed which is in good
     faith disputed in writing by Shipper and is ultimately determined to be in
     error; provided, however, interest shall be due if such amount billed is
     found not to be in error. If a portion of an invoice is disputed, Shipper
     shall pay when due the portion of the invoice not in dispute. If such
     failure to pay continues for thirty (30) days after the payment due date,
     Bay Gas may suspend deliveries of gas, subject to Bay Gas providing
     forty-eight (48) hours written notice, during normal working hours, of such
     intention to suspend deliveries; provided, however, that if Shipper, in
     good faith, disputes the amount of any such bill or part thereof and pays
     to Bay Gas such amounts as Shipper concedes to be correct, and


                                       11

<PAGE>   31






     furnishes and maintains a good and sufficient surety bond in an amount, and
     with sureties satisfactory to Bay Gas, conditioned upon the payment of any
     amounts ultimately found due upon such bills after a final determination,
     then Bay Gas shall not be entitled to suspend further delivery due to
     failure to pay such bills. In the event Shipper's financial position
     significantly deteriorates from that on the execution date of the Storage
     or Transportation Service Agreement, advance cash payments or acceptable
     security (including but not limited to an irrevocable letter of credit from
     a financial institution in an amount acceptable to Bay Gas) shall be given
     by Shipper upon demand of Bay Gas. Bay Gas may, without waiving any other
     rights or remedies it may have, withhold further delivery until such
     payment is received. In the event Bay Gas pursues collection on late
     payment, Shipper shall be liable for all expenses and costs, including
     court costs and attorneys' fees, incurred as a result of such failure to
     pay on time.

C.   Tax Reimbursement. Shipper agrees to reimburse Bay Gas for all new taxes
     (federal, state, local or other) that may be levied upon or paid by Bay
     Gas, with respect to the services performed hereunder.

D.   Examination of Books, Records and Charts. Each party shall have the right
     during reasonable working hours to examine the books, records and charts of
     the other party to the extent necessary to verify the accuracy of any
     statement, payment calculations or determinations made pursuant to the
     provisions contained herein. If any such examination shall reveal, or if
     either party shall discover, any error in its own or the other party's
     statements, payment calculations or determinations, then proper adjustment
     and correction thereof shall be made as promptly as practicable thereafter.
     The accuracy of any statement, payment calculations or determinations made
     pursuant to the provisions contained herein shall be conclusively presumed
     to be correct after two (2) years from the end of the calendar year in
     which the charts and records were generated or prepared if not challenged
     in writing prior thereto.



                                   SECTION XI.
                      Possession and Non-Odorization of Gas

         As between Shipper and Bay Gas, Shipper shall be in exclusive control
and possession of the gas deliverable and responsible for any damage or injury
caused thereby until the same shall have been received by Bay Gas for injection
at the storage facilities, or until delivered at the transportation facilities,
and after delivery of the gas for the account of Shipper for withdrawal at the
storage facilities, or after redelivery for the account of Shipper at the
transportation facilities. After delivery of gas for injection or transportation
by Shipper to Bay Gas, and until delivery by Bay Gas to Shipper or Shipper's
designee upon withdrawal or until redelivery after transportation, Bay Gas shall
be in exclusive control and possession thereof and responsible for any injury or
damage caused thereby. Neither Bay Gas nor Shipper assume any obligation to
odorize any gas delivered to the other.



                                       12

                                  SECTION XII.
                                    Warranty

         Shipper warrants that it will have and maintain good and marketable
title or the right to deliver for a third party owning good and marketable title
all gas tendered for injection, storage and withdrawal under a Storage Service
Agreement, and all gas delivered for transportation under a Transportation
Service Agreement, and that such gas shall be free and clear of all liens and
adverse claims; and each party agrees, with respect to the gas delivered by it,
to indemnify the other against all suits, actions, debts, accounts, damages,
costs (including attorney's fees), losses and expenses arising from or out of
any adverse claims of any and all persons to or against said gas.


                                  SECTION XIII.
                             Government Regulations

A.   All of the provisions of any Storage or Transportation Service Agreement
     are hereby expressly made subject to all present and future applicable
     federal or state laws, orders, rules and regulations of governmental
     authorities having jurisdiction. Except as otherwise provided herein, in
     the event any provision of a Storage or Transportation Service Agreement or
     of these General Terms and Conditions is found to be inconsistent with or
     contrary to any such law, order, rule or regulation, the latter shall be
     deemed to control, and the Storage or Transportation Service Agreement and
     these General Terms and Conditions, to the extent possible, shall be
     regarded as modified accordingly and as so modified shall continue in full
     force and effect.

B.   The parties hereto recognize that a Storage or Transportation Service
     Agreement has been entered into by Bay Gas in the good faith understanding
     that all acts, obligations and services performed by Bay Gas hereunder, and
     the charges therefor, are exempt from the regulation of FERC or any
     successor federal governmental authority, except as presently provided by
     Section 311(a)(2) of the NGPA and FERC's relevant regulations thereunder.
     Bay Gas reserves the right to terminate a Storage or Transportation Service
     Agreement immediately if, in the opinion of counsel for Bay Gas, any act
     shall occur or be seriously threatened which is in any way inconsistent
     with such understanding.

C.   Equal Employment Opportunity. Bay Gas and Shipper agree to comply with any
     and all applicable executive orders and acts pertaining to equal employment
     opportunity.



                                  SECTION XIV.
                                  Force Majeure

A.   In the event of either party being rendered unable, wholly or in part, by
     reason of force majeure to carry out its obligations under any


                                       13

<PAGE>   33






     Storage or Transportation Service Agreement (other than the obligation to
     make payment of amounts due hereunder), it is agreed that such party shall
     give notice and reasonably full particulars of such force majeure, in
     writing or by facsimile, to the other party within a reasonable time after
     the occurrence of the cause relied on, and the obligations of the party
     giving such notice, so far as they are affected by such force majeure,
     shall be suspended during the continuance of any inability so caused, but
     for no longer period, and such cause shall, so far as possible, be remedied
     with all reasonable dispatch.


B.   The term, "force majeure," as employed herein shall mean acts of God;
     strikes, lockouts, or other industrial disturbances; conditions arising
     from a change in governmental laws, orders, rules or regulations; acts of
     public enemy; wars; blockades; insurrections; riots; epidemics; landslides;
     lightning; earthquakes; fires; storms; floods; washouts; arrests and
     restraints of governments and people; civil disturbances; explosions;
     breakage or accident to machinery or lines of pipe; the necessity for
     making repairs, tests or alterations to machinery or lines of pipe;
     freezing of wells or lines of pipe; partial or entire failure of wells,
     processing or gasification and gas manufacturing facilities; and any other
     causes, whether of the kind herein enumerated or otherwise, not within the
     control of the party claiming suspension, and which by the exercise of due
     diligence, such party is unable to prevent or overcome. Such term shall
     likewise include: (a) those instances where either Bay Gas or Shipper is
     required to obtain servitudes, rights-of-way, grants, permits or licenses
     to enable such party to fulfill its obligations under a Storage or
     Transportation Service Agreement; the inability of such party in acquiring,
     at reasonable costs, and after the exercise of reasonable diligence, such
     servitudes, rights-of-way, grants, permits or licenses, and (b) those
     instances where either Bay Gas or Shipper is required to furnish materials
     and supplies for the purpose of constructing or maintaining facilities or
     is required to secure permits or permissions from any governmental agency
     to enable such party to fulfill its obligations under a Storage or
     Transportation Service Agreement; the inability of such party to acquire,
     or the delays on the part of such party in acquiring, at reasonable costs,
     and after the exercise of reasonable diligence, such materials and
     supplies, permits and permissions. Force majeure shall not include failure
     of gas supply due to pricing considerations.

C.   It is understood and agreed that the settlement of strikes or lockouts
     shall be entirely within the discretion of the party having the difficulty,
     and that the above requirement that any force majeure shall be remedied
     with all reasonable dispatch shall not require the settlement of strikes or
     lockouts by acceding to the demands of the opposing party when such course
     is inadvisable in the discretion of the party having the difficulty.



                                   SECTION XV.

                                     Notices

         Except as herein otherwise provided, any communication, notice,
request, demand, statement or bill provided for in a Storage or Transportation
Service Agreement which any party may desire to give to any other party shall be
made in writing and mailed by first class mail to the post office address of the
party intended to receive the same, as the case may be, at the addresses each
respective party shall designate in the Storage or Transportation Service
Agreement or change by subsequent formal written notice to the other. Routine
communications, including monthly statements and payments, may be mailed by
either certified or ordinary first class mail.


                                  SECTION XVI.
                                Creditworthiness

         Bay Gas shall not be required to commence service or, subject to the
following timing provisions, to continue to provide service under a Storage or
Transportation Service Agreement with any Shipper, that (a) is or has become
insolvent; (b) has applied for bankruptcy under Chapter 11 of the Bankruptcy
Code, or which is subject to similar proceedings under state or federal law; or
(c) when requested by Bay Gas to demonstrate creditworthiness, fails to do so in
Bay Gas' reasonable judgment, in light of previous payment experience and the
prudent credit analysis of information available; provided, however, that any
such Shipper that is receiving service shall continue to receive service for a
period of fifteen (15) days after written notice by Bay Gas of any such
circumstance, and shall continue thereafter to receive service if, within such
fifteen (15) day notice period, such Shipper (a) deposits with Bay Gas and
maintains, on account, an amount which would be due for three (3) months service
at the full Maximum Daily Withdrawal Quantity, or the full Maximum Daily
Transportation Quantity, including an amount of the current gas imbalance plus,
an amount equal to the three (3) highest cashout payments, if any, incurred
during the previous twelve months, or (b) furnishes good and sufficient
security, which may include an acceptable standby letter of credit, or monthly
prepayment agreement or other security as reasonably determined by Bay Gas, of a
continuing nature and in an amount equal to such amounts which would be due for
service. If such payment on account or payment security is not received within
such fifteen (15) day notice period, Bay Gas may, without waiving any rights or
remedies it may have, suspend further service for a period of ten (10) days. If
such payment on account or a payment security is not received within such ten
(10) day suspension period, then Bay Gas shall no longer be obligated to
continue to provide service to such Shipper. Further, if such payment on account
or a payment security is not received within sixty (60) days after the end of
such suspension period, Bay Gas may terminate its obligations to provide service
under all agreements between Shipper and Bay Gas, which termination shall not
affect any of Bay Gas' claims or remedies it may have under any Storage or
Transportation Service Agreement.



                                  SECTION XVII.
                                  Miscellaneous

A.   Headings and Subheadings. The headings and subheadings contained in the
     Storage or Transportation Service Agreement are used solely for convenience
     and do not constitute a part of the Storage or Transportation Service
     Agreement between the parties hereto, nor should they be used to aid in any
     manner in construing the Storage or Transportation Service Agreement.

B.   Successors and Assigns. The Storage or Transportation Service Agreement
     shall be binding upon and inure to the benefit of the respective successors
     and assigns of the parties hereto, but no assignment shall relieve any
     party of its obligations hereunder unless such party is expressly released
     in writing from said obligations by the party to which it is obligated.

C.   Entire Agreement. The Storage or Transportation Service Agreement, the
     Statement of Conditions for NGPA Section 311(a)(2) for Gas Storage and
     Transportation Services, and these General Terms and Conditions constitute
     the entire agreement of the parties hereto as to the matters contained
     herein, and there are no oral promises, agreements or warranties affecting
     same.

D.   Non-Waiver. The waiver of any default or right to require performance under
     a Storage or Transportation Service Agreement shall not operate as a waiver
     of any future default or right to require performance, whether of like or
     different character or nature.

E.   Jurisdiction and Venue. The parties agree that a Storage or Transportation
     Service Agreement shall be governed by and construed in accordance with the
     laws of the State of Alabama, excluding any conflicts of law, rule or
     principle that might refer such construction to the laws of another state
     and that venue shall be in the State of Alabama for services performed in
     Alabama, with respect to any cause of action brought under or with respect
     to a Storage or Transportation Service Agreement.

F.   Confidentiality. The terms of any Storage or Transportation Service
     Agreement shall be kept confidential by the parties except to the extent
     that any information must be disclosed to a third party as required by law,

                            BAY GAS STORAGE COMPANY's
                           STATEMENT OF CONDITIONS FOR
                           NGPA SECTION 311 (a)(2) GAS
                       STORAGE AND TRANSPORTATION SERVICES

                            Dated December 22, 1998.


         Bay Gas Storage Company, Ltd. ("Bay Gas"), a natural gas storage public
utility that qualifies as an intrastate pipeline company providing services
within the meaning of Natural Gas Policy Act of 1978 ("NGPA") Section 2 (16) and
Section 284.1 (a) of the Federal Energy Regulatory Commission's ("Commission")
regulations, files this amended Statement of Conditions For NGPA Section 311
(a)(2) Gas Storage and Transportation Services, pursuant to the Commission's
regulations. 18 C.F.R. Section 284.123 (e). Firm and interruptible gas storage
and transportation-only services, on terms and conditions authorized by the
Commission and accepted by Bay Gas, shall be provided by Bay Gas pursuant to
NGPA Section 311 (a)(2), 15 U.S.C. Section 3371 (a)(2), and the Commission's
implementing Orders, Rules and Regulations, to qualified Shippers that comply
with the conditions set forth in this Statement and with the terms and
conditions contained in Bay Gas' Storage or Transportation Service Agreement
executed with Shipper.


                                       I.

                       BAY GAS' BASIC STATUS AND FUNCTION

         Bay Gas is a gas storage public utility, certificated by the Alabama
Public Service Commission and subject to regulation by that Commission, which
qualifies as an intrastate pipeline company providing storage and transportation
services within the meaning of NGPA Section 2 (16) and Section 284.1 (a) of this
Commission's regulations. Any such NGPA Section 311 (a)(2) services that Bay Gas
provides will be consistent with, and shall not infringe on, Bay Gas' status and
function as a non-Federal-jurisdictional intrastate pipeline, and shall not
subject Bay Gas to this Commission's Natural Gas Act jurisdiction. 18 C.F.R.
Section 284.3.




<PAGE>   37






                                       II.

                               QUALIFIED SHIPPERS

         Besides other conditions contained in this Statement, Bay Gas' services
are available only to a Shipper that enters into a Service Agreement mutually
acceptable to Bay Gas and Shipper. All transactions for storage or
transportation of gas that has flowed, or will flow, in interstate commerce must
qualify under NGPA Section 311 (a)(2) and 18 C.F.R. Part 284 of Subchapter I.
If, in the opinion of Bay Gas' counsel, such qualified status of Shipper or its
proposed transaction is in doubt, then Shipper must apply for and receive a
final, non-appealable ruling from this Commission, or successor agency thereto,
affirming such qualifying status of Shipper and its proposed transaction, prior
to commencement of services by Bay Gas.

                                      III.

                CAPACITY AVAILABILITY, SCHEDULING AND ALLOCATIONS
                                AND CURTAILMENTS

A.   Capacity Availability

     1.   Storage service shall be conditioned on availability of sufficient
          injection rate capacity, field storage capacity and withdrawal rate
          capacity (collectively called "Capacity," and including pipeline
          transportation service capacity) to perform the service in accordance
          with the terms and conditions set forth in this Statement of
          Conditions without detriment or disadvantage to services by or for the
          account of Bay Gas. Transportation service shall be conditioned on
          availability of sufficient Capacity to perform the service in
          accordance with the terms and conditions set forth in this Statement
          of Conditions without detriment or disadvantage to services by or for
          the account of Bay Gas. Bay Gas reserves all rights to retain
          sufficient Capacity for its intrastate, non-Federal-jurisdictional
          firm and interruptible services and for its operational swings
          attributable to firm and interruptible storage services prior to
          making Capacity available


<PAGE>   38






          by contract to NGPA Section 311 (a)(2) Shippers. Once Capacity is made
          available to NGPA Section 311 (a)(2) Shippers, such Capacity shall be
          scheduled, allocated or curtailed only as set forth in Sections III. B
          and C here.

     2.   Storage service availability further shall be conditioned on Bay Gas
          receiving an acceptable market value, in Bay Gas' sole judgment, for
          such storage services, determined when a request for storage service
          is received. Bay Gas reserves all rights to refuse a request for
          storage service that, in Bay Gas' sole judgment, might provide less
          than market value. Apart from such Bay Gas judgment as to market
          value, Bay Gas' judgment shall be exercised on a non-discriminatory
          basis.

     3.   Criteria applied to requests for NGPA Section 311 (a)(2) services
          shall be the same as criteria applied to requests for intrastate,
          non-Federal-jurisdictional services.

     4.   Shipper shall be responsible for making all arrangements for its
          transportation of gas to be injected into or withdrawn from storage
          through Bay Gas' storage services. Bay Gas reserves all rights to
          refuse storage service for any otherwise qualified Shipper if Bay Gas
          determines that such storage would be detrimental to Bay Gas' storage
          operations in any way, including, without limitation, Bay Gas' storage
          compression and affected processing operations.

B.       Scheduling and Allocations

         Bay Gas shall schedule contracted services according to these
         principles:

                  1. Nomination deadlines shall be as prescribed in Bay Gas'
                  General Terms and Conditions. 

                  2. Bay Gas will be under no obligation to schedule the
                  injection of gas into storage or the withdrawal of gas from
                  storage until Bay Gas has confirmed the availability of
                  Shipper's transportation




<PAGE>   39






          service to or from Bay Gas' storage services for the gas concerned.
          Subject to the foregoing subsection "1." and this subsection "2.",
          firm storage and transportation services shall be scheduled before
          interruptible services in all instances, regardless of the relative
          service rates to be paid.

     3.   In-field transfer of title (transfer of gas balances in the storage
          field between storage service agreements) may be made only with Bay
          Gas' approval.

     4.   Interruptible storage service Shippers paying a higher Unit Rate, as
          defined in Bay Gas' General Terms and Conditions, shall be scheduled
          ahead of interruptible storage service Shippers paying a lower Unit
          Rate. If, because of changes in available Capacity at any time, Bay
          Gas is required to reschedule interruptible Shippers that are
          injecting, storing or withdrawing gas and are paying the same Unit
          Rate, then the Capacity shall be rescheduled pro rata based on
          applicable contract quantities for said Shippers.

     5.   Bay Gas reserves the right to interrupt service to an interruptible
          Shipper injecting, storing or withdrawing gas, in order to enable Bay
          Gas to provide service to another, bumping, interruptible Shipper
          injecting, storing or withdrawing gas, if such Shipper is paying a
          higher Unit Rate to Bay Gas.

     6.   All overrun volumes in excess of a storage service Shipper's contract
          quantities nominated for delivery by Shipper shall be scheduled
          according to the above subsections "4." and "5." only after all other
          storage service Shippers' nominated volumes equal to or less than each
          Shippers' Maximum Daily Injection Quantity or Maximum Daily Withdrawal
          Quantity are scheduled.

     7.   Bay Gas may reschedule Capacity on a daily basis, or on such other
          periodic basis as is necessary for Bay Gas to recognize the priority
          of new storage or transportation service Shippers or any changes in
          the priorities of existing such Shippers, and to


<PAGE>   40






                  conform to its storage system operational requirements. Such
                  priorities or changes will include, but will not be limited
                  to, those instances involving a storage service Shipper paying
                  a higher Unit Rate for interruptible service and firm storage
                  service Shippers changing volumes within their Maximum Daily
                  Injection Quantity or Maximum Daily Withdrawal Quantity.
                  However, such changes in scheduling shall not at any time bump
                  any existing firm Shipper.

         C.       Curtailments

     1.      General. If curtailment of storage or transportation service is
             required, volumes shall be curtailed in the reverse order of the
             priority in effect at the time of curtailment established during
             scheduling as set forth in Section "III. B" above. Intrastate,
             non-Federal-jurisdictional firm and interruptible services shall be
             curtailed in a manner determined solely by Bay Gas, but in no event
             shall such curtailments have a different priority than similar
             types of services for NGPA Section 311 (a)(2) Shippers.

     2.      Reduction of Services. Without limitation to the foregoing, Bay Gas
             shall have the right to reduce receipts, deliveries, injections or
             withdrawals of gas on any day below a storage service Shipper's
             Maximum Daily Injection Quantity or Maximum Daily Withdrawal
             Quantity, or below the storage rights applicable, for repair,
             overhaul, replacement or construction of pipelines, compressors,
             metering, regulating or other production, gathering and
             transmission facilities and equipment, or to maintain system
             integrity; provided, however, that with respect to routine repair
             and maintenance, Bay Gas will implement restrictions for scheduling
             purposes only, not for curtailment, and will attempt to schedule
             such activity during a period when it will not result in limitation
             of firm service or when such limitation will be




<PAGE>   41






          minimized, and after consulting with the Shippers that could be
          affected.

     3.   Notice of Curtailment. For shippers under all firm services, Bay Gas
          shall provide notice of any curtailment as far in advance as feasible.
          Services reserved by Bay Gas for system operations shall be curtailed
          last, in consideration of the need to preserve system integrity. If
          capacity is curtailed and two or more firm Shippers have the same
          priority according to this Section "III. C", firm Shippers shall be
          allocated their pro rata share of capacity based on their Maximum
          Daily Injection Quantity or Maximum Daily Withdrawal Quantity or
          Maximum Daily Transportation Quantity, as applicable. If firm Shippers
          nominate fewer than their respective curtailment period entitlements,
          the difference shall be allocated pro rata among those firm Shippers
          with unsatisfied nominations. All non-firm Shippers shall be allocated
          their pro rata share of Capacity based on their nominations in effect
          at the time of the curtailment.

     4.   Limitation of Firm Services. While firm services are not ordinarily
          interrupted by nominations for firm service within Shipper's Maximum
          Daily Injection Quantity or Maximum Daily Withdrawal Quantity or
          Maximum Daily Transportation Quantity, Bay Gas may decline to schedule
          firm service for any of the following reasons:

               (a)  if Shipper tenders gas which does not conform to applicable
                    pressure requirements of the Storage or Transportation
                    Service Agreement

               (b)  if Shipper tenders gas which does not conform to the gas
                    quality requirements of both the upstream and downstream
                    entities' gas quality requirements

               (c)  for reasons of force majeure

               (d)  due to routine repair and maintenance to be reasonably
                    determined by Bay Gas



<PAGE>   42






               (e)  due to delinquency in payment by Shipper

               (f)  to rectify imbalances or to conform physical flows to
                    nominations

               (g)  to maintain system integrity, or

               (h)  if there is a dispute over title, ownership or right to
                    tender, receive or deliver gas.


                                       IV.

                         MINIMUM STORAGE SERVICE VOLUME

         Bay Gas shall not be obligated to furnish storage service to any
Shipper whose average daily gas volume tendered for storage in a given month is
less than 100 MMBtu per day. Such storage Shipper's obligation to tender gas for
delivery shall be suspended and modified for the time and to the extent that Bay
Gas does not accept deliveries due to Shipper's inability to deliver such
minimum average daily volume. If the amount of gas subsequently tendered for
delivery once again is less than such minimum average daily volume, Bay Gas
shall have the right to cancel the Storage Service Agreement at any time on
thirty (30) days written notice to Shipper. Bay Gas shall be deemed released
from all obligations and liabilities, direct or indirect, under such Storage
Service Agreement on the effective date of such a cancellation.


                                       V.

                              RECEIPT AND DELIVERY

         Bay Gas shall have sole operational control over the injection of gas
into, the retention of gas within, and the withdrawal of gas from, Bay Gas'
system storage facilities. A Shipper seeking to direct gas into storage shall
nominate "Storage" as the Point of Delivery on Bay Gas' system and shall
identify the number of the Storage Service Agreement to be used for the receipt
of such gas into storage. A Shipper seeking to withdraw gas from storage shall
nominate "Storage" as the Point of Redelivery from Bay Gas' system and shall
identify the number of the Storage Service Agreement under which the gas is to
be withdrawn from storage. Bay Gas shall have sole




<PAGE>   43






operational control over the transportation of gas on Bay Gas' system from the
Point of Delivery to the Point of Redelivery. For transportation service,
"Delivery" shall mean the act of causing gas to be transported to the Points of
Delivery, and "Redelivery" shall mean the transportation of gas from the Points
of Delivery to the Points of Redelivery.


                                       VI.

                          GENERAL TERMS AND CONDITIONS
                       FOR GAS STORAGE AND TRANSPORTATION

         Amended General Terms and Conditions to Bay Gas Storage Company, Ltd.'s
Storage and Transportation Service Agreements, dated December 22, 1998, are
incorporated by reference as part of this Statement of Conditions. Shipper's
failure to comply with the provisions in Section II, Nominations, Balancing And
Excess Deliveries, of such General Terms and Conditions shall relieve Bay Gas of
its obligation to perform services, and, if such failure to comply unreasonably
interferes, in Bay Gas' judgment, with Bay Gas' control over its system
facilities, then Bay Gas may, at its option, cease services and terminate any
related Service Agreements or other agreements, without limitation of Bay Gas'
rights or remedies at law or in equity.


                                      VII.

                           RIGHT TO TERMINATE SERVICES

         Bay Gas reserves the right to discontinue, on a non-discriminatory
basis, all services that subject Bay Gas to the non-discriminatory access
requirements of 18 C.F.R. Part 284, and any subsequent Commission Orders, Rules
or Regulations applicable to such services. Bay Gas may cancel the affected
Service Agreements at any time on ninety (90) days prior written notice to
Shippers if Bay Gas has no other reasonable options available that will allow
the continuation of such Service Agreements. Bay Gas shall be relieved of all
obligations and liabilities on the effective date of such


<PAGE>   44






notice of discontinuance and cancellation. Bay Gas additionally reserves the
right to terminate any interruptible Service Agreement if the Shipper either has
not executed the Service Agreement within thirty (30) days of receiving such
Agreement, or has failed to nominate service under such Agreement within one (1)
year after execution of the Agreement.


                                      VIII.

                      COMPLIANCE WITH LAW AND SURVIVABILITY

         If any part of this Statement of Conditions conflicts with, or
violates, any Commission or other Judicial, Governmental or Regulatory Body's
Orders, Rules or Regulations, such part shall be deemed void, but shall not
affect the remaining provisions of this Statement. Bay Gas shall not be liable
to any party with a Service Agreement subject to this Statement that loses
priority status or any other rights enumerated in this Statement because of the
issuance by the Commission or other Judicial, Governmental or Regulatory Body of
any Orders, Rules or Regulations affecting this Statement of Conditions.


                                       IX.

                     CHANGES TO THIS STATEMENT OF CONDITIONS

         Bay Gas reserves the right to add to, delete or modify the conditions
in this Statement without prior notice.


                                       X.

                      AUTHORITY OF STATEMENT OF CONDITIONS

         This Statement of Conditions, and the incorporated General Terms and
Conditions (see Section "VI." above) take precedence over conflicting language
in any of Bay Gas' Service Agreements or amendments thereto, unless such
language specifically states that it is an exception to this Statement, and then
only to the extent of such stated exception.
