                          NOTES TO FINANCIAL STATEMENTS


INSTRUCTIONS:     The space below is provided for important notes regarding the
                  financial statements or any account thereof. Furnish
                  particulars as to any significant contingent assets or
                  liabilities existing at the end of the year. Notes relating to
                  financial statements shown elsewhere in this report may be
                  indicated here by reference.



- -------------------------------------------------------------------------------

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      a.    Property, Plant and Equipment and Related Depreciation

            Property, Plant and Equipment is stated at historical cost.
            Depreciation is provided on a composite straight-line basis using
            the average of depreciable property at the beginning and end of each
            year.

      b.    Income Taxes

            The Corporation provides deferred taxes with respect to timing
            differences in the recognition of revenues and expenses for tax and
            accounting purposes. The major difference results from using
            accelerated depreciation for tax purposes. The Corporation is
            included in the Consolidated Federal Income Tax Return filed for the
            Columbia Energy Group and Subsidiaries.

      c.    Pension Costs

            The Corporation participates in the Retirement Income Plan of the
            Columbia Energy Group. This is a trusteed noncontributory Retirement
            Income Plan which, with certain minor exceptions, covers all regular
            employees. The Service Corporation's portion amounted to
            ($392,920.00) in 1999 and ($1,066,272) in 1998, including the
            amortization of unfunded prior service costs.

      d.    Leases

            Payments made by the Corporation in connection with operating leases
            are charged to expense as incurred. No capitalized leases existed in
            1999.

      e.    Account Numbers

            The Corporation uses certain FERC accounts which do not match
            existing SEC accounts; therefore, the year-end balances of the
            following FERC accounts were reclassified to a corresponding SEC
            account.

f.    Post-Retirement Benefits Other Than Pensions

      During 1991, the System adopted SFAS No. 106, Employer's Accounting for
      Post-Retirement Benefits Other Than Pensions, retroactive to January 1,
      1991. The Corporation has elected to record and defer the full amount of
      its estimated accumulated post-retirement obligations other than pensions.
      These obligations total $4,874,000 as of December 31, 1999, and represent
      the actuarial present value of the post-retirement benefits to be paid to
      current employees and retirees based on services rendered.

g.    System Money Pool

      The Parent Company and its subsidiaries participate in the System Money
      Pool (Pool) which is administered by the Corporation on behalf of the
      participants.

      Participants invest their excess funds to the Pool. Short-term financing
      requirements of participants, with the exception of the Parent Company,
      are satisfied by advances from the Pool. Excess funds in the Pool are
      invested by the Corporation on a short-term basis on behalf of the
      depositors.

      Participants depositing funds in the Pool share in the interest earned on
      these investments plus interest paid to the Pool by borrowers on a basis
      proportionate to their investment in the Pool. Participants borrowing from
      the Pool pay interest at the rate equivalent to the composite rate on
      short-term transactions of the Pool. Participants may withdraw their
      investments in the Pool at any time. Borrowings from the Pool are payable
      on demand, and may be prepaid at any time without premium or penalty.

                          NOTES TO STATEMENT OF INCOME



INSTRUCTIONS:  The space below is provided for important notes regarding the
               statement of income or any account thereof. Furnish particulars
               as to any significant increase in services rendered or expenses
               incurred during the year. Notes relating to financial statements
               shown elsewhere in this report may be indicated here by
               reference.

Outside Services Employed increased $12.2 million over 1998. This increase is
primarily attributable to a Procurement Project ($7.7 million) in which Columbia
partnered with A. T. Kearney, an operations consulting firm with significant
expertise in the area of procurement, to do an in-depth assessment of the
procurement of external goods and services (except for natural gas purchases)
across all Columbia companies. The objective was to produce savings and
operational excellence in all aspects of procurement. The project team
identified opportunities for Columbia companies to save $40 million to $65
million annually in the goods and services they purchase.

Other increases in outside services were attributable to consulting related to
Y2K and merger activity.

For additional notes, see Page 22, Notes to Financial Statements.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided and the number of labor hours available to the customer for various
projects/services. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific product/service, such as hourly labor rates,
computer-related charges, building rent and utilities. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as labor benefits, and the expenses of administering the Shared
Services Center. Overhead costs are specifically identified on the Customer's
books as associated with individual services. The "total cost of service" is the
sum of the Direct and the Overhead costs. It is the Total amount that Provider
will monitor through the Service Performance Reports.

OTHER MATTERS

The Provider and Customer acknowledge the following role relationships:

         Customer - Training manager and human resource professionals who serve
         as the primary business partners to operating company management and
         staff in managing training/education needs and issues in their
         respective organizations.

         Provider - Training professionals who serve as primary consultants to
         Customers, and provide training design expertise, implementation
         support and consulting to operating company training
         managers/coordinators, operations managers and human resource staff in
         achieving their objectives.

The Provider and Customer also intend that prior to the start of the provision
of any service as contemplated in this service level plan, the Primary Provider
and Primary Customer will define expectations that could include any of the
following elements: project/service definition, objectives/goals, deliverables,
people to be involved, role definitions, time schedules, progress review/report
frequency, and cost, time and support requirements/limitations.

The Provider and Customer understand that a portion of the projected service
volume and costs will be directed to support the efforts of the Shared Service
Center organization, which in turn is providing direct support to other areas of
the Customer's state/regional organization.

While the Program Development Evaluation Questionnaire, Training Program
Evaluation and monthly/quarterly Service performance Reports will be a key
Source of Information to formally monitor and measure the Provider's progress in
achieving key performance measures, the Provider and Customer may agree to more
frequent review discussions and evaluations.

MODIFICATIONS TO THE PLAN

This service level plan anticipated the need of 1.45 FTEs annually, or .12 FTEs

requirements. Amendments to this plan will be issued if a renegotiation occurs.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided and the number of labor hours available to the customer for various
projects/services. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific product/service, such as hourly labor rates,
computer-related charges, building rent and utilities. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as labor benefits, and the expenses of administering the Shared
Services Center. Overhead costs are specifically identified on the Customer's
books as associated with individual services. The "total cost of service" is the
sum of the Direct and the Overhead costs. It is the Total amount that Provider
will monitor through the Service Performance Reports.

OTHER MATTERS

The Provider and Customer acknowledge the following role relationships:

         Customer - Training manager and human resource professionals who serve
         as the primary business partners to operating company management and
         staff in managing training/education needs and issues in their
         respective organizations.

         Provider - Training professionals who serve as primary consultants to
         Customers, and provide training design expertise, implementation
         support and consulting to operating company training
         managers/coordinators, operations managers and human resource staff in
         achieving their objectives.

The Provider and Customer also intend that prior to the start of the provision
of any service as contemplated in this service level plan, the Primary Provider
and Primary Customer will define expectations that could include any of the
following elements: project/service definition, objectives/goals, deliverables,
people to be involved, role definitions, time schedules, progress review/report
frequency, and cost, time and support requirements/limitations.

The Provider and Customer understand that a portion of the projected service
volume and costs will be directed to support the efforts of the Shared Service
Center organization, which in turn is providing direct support to other areas of
the Customer's state/regional organization.

While the Program Development Evaluation Questionnaire, Training Program
Evaluation and monthly/quarterly Service performance Reports will be a key
Source of Information to formally monitor and measure the Provider's progress in
achieving key performance measures, the Provider and Customer may agree to more
frequent review discussions and evaluations.

MODIFICATIONS TO THE PLAN

This service level plan anticipated the need of 7.26 FTEs annually, or .605 FTEs
per month. Service Provider and Customer will monitor Customer usage. If usage
may exceed established level, Provider and Customer will reprioritize provision
of requested service or renegotiate costs to provide incremental service
requirements. Amendments to this plan will be issued if a renegotiation occurs.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided and the number of labor hours available to the customer for various
projects/services. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific product/service, such as hourly labor rates,
computer-related charges, building rent and utilities. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as labor benefits, and the expenses of administering the Shared
Services Center. Overhead costs are specifically identified on the Customer's
books as associated with individual services. The "total cost of service" is the
sum of the Direct and the Overhead costs. It is the Total amount that Provider
will monitor through the Service Performance Reports.

OTHER MATTERS

The Provider and Customer acknowledge the following role relationships:

     Customer - Training manager and human resource professionals who serve as
     the primary business partners to operating company management and staff in
     managing training/education needs and issues in their respective
     organizations.

     Provider - Training professionals who serve as primary consultants to
     Customers, and provide training design expertise, implementation support
     and consulting to operating company training managers/coordinators,
     operations managers and human resource staff in achieving their objectives.

The Provider and Customer also intend that prior to the start of the provision
of any service as contemplated in this service level plan, the Primary Provider
and Primary Customer will define expectations that could include any of the
following elements: project/service definition, objectives/goals, deliverables,
people to be involved, role definitions, time schedules, progress review/report
frequency, and cost, time and support requirements/limitations.

The Provider and Customer understand that a portion of the projected service
volume and costs will be directed to support the efforts of the Shared Service
Center organization, which in turn is providing direct support to other areas of
the Customer's state/regional organization.

While the Program Development Evaluation Questionnaire, Training Program
Evaluation and monthly/quarterly Service performance Reports will be a key
Source of Information to formally monitor and measure the Provider's progress in
achieving key performance measures, the Provider and Customer may agree to more
frequent review discussions and evaluations.

MODIFICATIONS TO THE PLAN

This service level plan anticipated the need of 2.60 FTEs annually, or .216 FTEs
per month. Service Provider and Customer will monitor Customer usage. If usage
may exceed established level, Provider and Customer will reprioritize provision
of requested service or renegotiate costs to provide incremental service
requirements. Amendments to this plan will be issued if a renegotiation occurs.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided and the number of labor hours available to the customer for various
projects/services. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific product/service, such as hourly labor rates,
computer-related charges, building rent and utilities. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as labor benefits, and the expenses of administering the Shared
Services Center. Overhead costs are specifically identified on the Customer's
books as associated with individual services. The "total cost of service" is the
sum of the Direct and the Overhead costs. It is the Total amount that Provider
will monitor through the Service Performance Reports.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided and the number of labor hours available to the customer for various
projects/services. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific product/service, such as hourly labor rates,
computer-related charges, building rent and utilities. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as labor benefits, and the expenses of administering the Shared
Services Center. Overhead costs are specifically identified on the Customer's
books as associated with individual services. The "total cost of service" is the
sum of the Direct and the Overhead costs. It is the Total amount that Provider
will monitor through the Service Performance Reports.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided and the number of labor hours available to the customer for various
projects/services. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific product/service, such as hourly labor rates,
computer-related charges, building rent and utilities. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as labor benefits, and the expenses of administering the Shared
Services Center. Overhead costs are specifically identified on the Customer's
books as associated with individual services. The "total cost of service" is the
sum of the Direct and the Overhead costs. It is the Total amount that Provider
will monitor through the Service Performance Reports.

OVERVIEW

The Shared Services Center (SSC) provides high-quality, necessary and
value-added support services to all the local distribution companies of the
Columbia Energy Group. The keystone of effective shared service arrangements is
a strong customer-service orientation. The shared services approach incorporates
mechanisms for (1) enhanced understanding and effective management of costs; (2)
continuously improving service quality; and (3) encouraging personal
accountability. If these objectives are to be met, it is essential to develop
enhanced methods of communicating between the operating companies and service
providers.

This Service Level Plan is a primary means of communication, incorporating the
mutual expectations of Columbia Gas of Kentucky, Inc. and Finance & Regulatory
Shared Services regarding specific types of services expected to be used, the
primary users, projected volumes, evaluation criteria and the projected cost of
each of those services for calendar year 1999. A strong provider-customer
relationship built upon the discussions and understandings reflected in this
Plan will better enable the distribution companies to have access to highly
valued services at low cost.

Through the SSC, services will be provided that are: (1) requested or agreed to
by the operating company customer; (2) evaluated on an ongoing basis according
to the agreed-upon performance measures; and (3) priced at cost, as required by
the Public Utility Holding Company Act of 1935, as amended.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided. "Direct" costs are those costs the Provider will incur explicitly to
provide the specific service, such as hourly labor rates, computer-related
charges and out-of-pocket expenses. "Overhead" costs represent the proportionate
share of the costs that are incurred to support all services, such as building
costs, labor benefits, and the expenses of administering the Shared Services
Center. Overhead costs are not specifically identified on the Customer's books
as associated with individual services. The "Total Cost of Service" is the sum
of the Direct and the Overhead costs.

OTHER MATTERS

For Services 10 through 12, the Provider and Customer also intend that:

1. Prior to the start of a regulatory project, Regulatory Shared Services will
   develop a mutually agreed-upon workplan with the state regulatory contact.
   Depending upon the scope of the project, the workplan may consist of a
   calendar of events, sources and uses of information, internal and external
   deadlines and the identification of special initiatives or issues. The
   workplan will specify responsibilities and performance measures that have
   been more generically detailed herein.

2. The successful development, presentation and support of a regulatory filing
   depend upon the availability, timeliness and quality of information provided
   from other functional areas. It is the responsibility of the state to either
   plan and coordinate directly with the other Shared Services units for time
   and resources, or to make arrangements for this information to be developed
   and provided by the state organization.

MODIFICATIONS TO THE PLAN

The Provider and Customer intend to address unanticipated changes to this Plan
for Services 10 through 12 by:

1. Certain actions or events that are out of the direct control of Regulatory
   Shared Services, such as adverse Commission Orders, late notice of required
   service, lack of access to needed information, etc., may result in the
   inability of Regulatory Shared Services to meet time, quality and cost goals.

2. The costs reflected herein are based on information available as of December
   31, 1998, and are subject to change as revised budgets are approved.

SHARED SERVICES CENTER                                   1999 SERVICE LEVEL PLAN

OVERVIEW

The Shared Services Center (SSC) provides high-quality, necessary and
value-added support services to all the local distribution companies of the
Columbia Energy Group. The keystone of effective shared service arrangements is
a strong customer-service orientation. The shared services approach incorporates
mechanisms for (1) enhanced understanding and effective management of cost; (2)
continuously improving service quality; and (3) encouraging personal
accountability. If these objectives are to be met, it is essential to develop
enhanced methods of communicating between the operating companies and service
providers.

This Service Level Plan is a primary means of communication, incorporating the
mutual expectations of Columbia Gas of Ohio, Inc. and Finance & Regulatory
Shared Services regarding specific types of services expected to be used, the
primary users, projected volumes, evaluation criteria and the projected cost of
each of those services for calendar year 1999. A strong provider-customer
relationship built upon the discussions and understandings reflected in this
Plan will better enable the distribution companies to have access to highly
valued services at low cost.

Through the SSC, services will be provided that are: (1) requested or agreed to
by the operating company customer; (2) evaluated on an ongoing basis according
to the agreed-upon performance measures; and (3) priced at cost, as required by
the Public Utility Holding Company Act of 1935, as amended.

                       PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided. "Direct" costs are those costs the Provider will incur explicitly to
provide the specific service, such as hourly labor rates, computer-related
charges and out-of-pocket expenses. "Overhead" costs represent the proportionate
share of the costs that are incurred to support all services, such as building
costs, labor benefits, and the expenses of administering the Shared Services
Center. Overhead costs are not specifically identified on the Customer's books
as associated with individual services. The "Total Cost of Service" is the sum
of the Direct and the Overhead costs.

OTHER MATTERS

For Services 10 through 12, the Provider and Customer also intend that:

1.   Prior to the start of a regulatory project, Regulatory Shared Services will
     develop a mutually agreed-upon workplan with the state regulatory contact.
     Depending upon the scope of the project, the workplan may consist of a
     calendar of events, sources and uses of information, internal and external
     deadlines and the identification of special initiatives or issues. The
     workplan will specify responsibilities and performance measures that have
     been more generically detailed herein.


2.   The successful development, presentation and support of a regulatory filing
     depend upon the availability, timeliness and quality of information
     provided from other functional areas. It is the responsibility of the state
     to either plan and coordinate directly with the other Shared Services units
     for time and resources, or to make arrangements for this information to be
     developed and provided by the state organization.


MODIFICATIONS TO THE PLAN

The Provider and Customer intend to address unanticipated changes to this Plan
for Services 10 through 12 by:

1.   Certain actions or events that are out of the direct control of Regulatory
     Shared Services, such as adverse Commission Orders, late notice of required
     service, lack of access to needed information, etc., may result in the
     inability of Regulatory Shared Services to meet time, quality and cost
     goals.

2.   The costs reflected herein are based on information available as of
     December 31, 1998, and are subject to change as revised budgets are
     approved.

SHARED SERVICES CENTER                                  1999 SERVICE LEVEL PLAN
                                   for Finance & Regulatory Services provided to
                                                  Columbia Gas of Maryland, Inc.




OVERVIEW

The Shared Services Center (SSC) provides high-quality, necessary and
value-added support services to all the local distribution companies of the
Columbia Energy Group. The keystone of effective shared service arrangements is
a strong customer-service orientation. The shared services approach incorporates
mechanisms for (1) enhanced understanding and effective management of costs; (2)
continuously improving service quality; and (3) encouraging personal
accountability. If these objectives are to be met, it is essential to develop
enhanced methods of communicating between the operating companies and service
providers.

This Service Level Plan is a primary means of communication, incorporating the
mutual expectations of Columbia Gas of Maryland, Inc. and Finance & Regulatory
Shared Services regarding specific types of services expected to be used, the
primary users, projected volumes, evaluation criteria and the projected cost of
each of those services for calendar year 1999. A strong provider-customer
relationship built upon the discussions and understandings reflected in this
Plan will better enable the distribution companies to have access to highly
valued services at low cost.

Through the SSC, services will be provided that are: (1) requested or agreed to
by the operating company customer; (2) evaluated on an ongoing basis according
to the agreed-upon performance measures; and (3) priced at cost, as required by
the Public Utility Holding Company Act of 1935, as amended.

                       PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided. "Direct" costs are those costs the Provider will incur explicitly to
provide the specific service, such as hourly labor rates, computer-related
charges and out-of-pocket expenses. "Overhead" costs represent the proportionate
share of the costs that are incurred to support all services, such as building
costs, labor benefits, and the expenses of administering the Shared Services
Center. Overhead costs are not specifically identified on the Customer's books
as associated with individual services. The "Total Cost of Service" is the sum
of the Direct and the Overhead costs.

OTHER MATTERS

For Services 10 through 12, the Provider and Customer also intend that:

1.   Prior to the start of a regulatory project, Regulatory Shared Services will
     develop a mutually agreed-upon workplan with the state regulatory contact.
     Depending upon the scope of the project, the workplan may consist of a
     calendar of events, sources and uses of information, internal and external
     deadlines and the identification of special initiatives or issues. The
     workplan will specify responsibilities and performance measures that have
     been more generically detailed herein.

2.   The successful development, presentation and support of a regulatory filing
     depend upon the availability, timeliness and quality of information
     provided from other functional areas. It is the responsibility of the state
     to either plan and coordinate directly with the other Shared Services units
     for time and resources, or to make arrangements for this information to be
     developed and provided by the state organization.

MODIFICATIONS TO THE PLAN

The Provider and Customer intend to address unanticipated changes to this Plan
for Services 10 through 12 by:

1.   Certain actions or events that are out of the direct control of Regulatory
     Shared Services, such as adverse Commission Orders, late notice of required
     service, lack of access to needed information, etc., may result in the
     inability of Regulatory Shared Services to meet time, quality and cost
     goals.

2.   The costs reflected herein are based on information available as of
     December 31, 1998, and are subject to change as revised budgets are
     approved.

SHARED SERVICES CENTER                                  1999 SERVICE LEVEL PLAN
                                   for Finance & Regulatory Services provided to
                                              Columbia Gas of Pennsylvania, Inc.




OVERVIEW

The Shared Services Center (SSC) provides high-quality, necessary and
value-added support services to all the local distribution companies of the
Columbia Energy Group. The keystone of effective shared service arrangements is
a strong customer-service orientation. The shared services approach incorporates
mechanisms for (1) enhanced understanding and effective management of costs; (2)
continuously improving service quality; and (3) encouraging personal
accountability. If these objectives are to be met, it is essential to develop
enhanced methods of communicating between the operating companies and service
providers.

This Service Level Plan is a primary means of communication, incorporating the
mutual expectations of Columbia Gas of Pennsylvania, Inc. and Finance &
Regulatory Shared Services regarding specific types of services expected to be
used, the primary users, projected volumes, evaluation criteria and the
projected cost of each of those services for calendar year 1999. A strong
provider-customer relationship built upon the discussions and understandings
reflected in this Plan will better enable the distribution companies to have
access to highly valued services at low cost.

Through the SSC, services will be provided that are: (1) requested or agreed to
by the operating company customer; (2) evaluated on an ongoing basis according
to the agreed-upon performance measures; and (3) priced at cost, as required by
the Public Utility Holding Company Act of 1935, as amended.

                       PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided. "Direct" costs are those costs the Provider will incur explicitly to
provide the specific service, such as hourly labor rates, computer-related
charges and out-of-pocket expenses. "Overhead" costs represent the proportionate
share of the costs that are incurred to support all services, such as building
costs, labor benefits, and the expenses of administering the Shared Services
Center. Overhead costs are not specifically identified on the Customer's books
as associated with individual services. The "Total Cost of Service" is the sum
of the Direct and the Overhead costs.

OTHER MATTERS

For Services 10 through 12 The Provider and Customer also intend that:

1.   Prior to the start of a regulatory project, Regulatory Shared Services will
     develop a mutually agreed-upon workplan with the state regulatory contact.
     Depending upon the scope of the project, the workplan may consist of a
     calendar of events, sources and uses of information, internal and external
     deadlines and the identification of special initiatives or issues. The
     workplan will specify responsibilities and performance measures that have
     been more generically detailed herein.

2.   The successful development, presentation and support of a regulatory filing
     depend upon the availability, timeliness and quality of information
     provided from other functional areas. It is the responsibility of the state
     to either plan and coordinate directly with the other Shared Services units
     for time and resources, or to make arrangements for this information to be
     developed and provided by the state organization.

MODIFICATIONS TO THE PLAN

The Provider and Customer intend to address unanticipated changes to this Plan

1.   Certain actions or events that are out of the direct control of Regulatory
     Shared Services, such as adverse Commission Orders, late notice of required
     service, lack of access to needed information, etc., may result in the
     inability of Regulatory Shared Services to meet time, quality and cost
     goals.

SHARED SERVICES CENTER                                   1999 SERVICE LEVEL PLAN
                                   For Finance & Regulatory Services provided to
                                                  Columbia Gas of Virginia, Inc.




OVERVIEW

The Shared Services Center (SSC) provides high-quality, necessary and
value-added support services to all the local distribution companies of the
Columbia Energy Group. The keystone of effective shared service arrangements is
a strong customer-service orientation. The shared services approach incorporates
mechanisms for (1) enhanced understanding and effective management of costs; (2)
continuously improving service quality; and (3) encouraging personal
accountability. If these objectives are to be met, it is essential to develop
enhanced methods of communicating between the operating companies and service
providers.

This Service Level Plan is a primary means of communication, incorporating the
mutual expectations of Columbia Gas of Virginia, Inc. and Finance & Regulatory
Shared Services regarding specific types of services expected to be used, the
primary users, projected volumes, evaluation criteria and the projected cost of
each of those services for calendar year 1999. A strong provider-customer
relationship built upon the discussions and understandings reflected in this
Plan will better enable the distribution companies to have access to highly
valued services at low cost.

Through the SSC, services will be provided that are: (1) requested or agreed to
by the operating company customer; (2) evaluated on an ongoing basis according
to the agreed-upon performance measures; and (3) priced at cost, as required by
the Public Utility Holding Company Act of 1935, as amended.

                       PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost for each service
the Customer expects to use. "Volume" measures the level of each service to be
provided. "Direct" costs are those costs the Provider will incur explicitly to
provide the specific service, such as hourly labor rates, computer-related
charges and out-of-pocket expenses. "Overhead" costs represent the proportionate
share of the costs that are incurred to support all services, such as building
costs, labor benefits, and the expenses of administering the Shared Services
Center. Overhead costs are not specifically identified on the Customer's books
as associated with individual services. The "Total Cost of Service" is the sum
of the Direct and the Overhead costs.

OTHER MATTERS

For Services 10 through 12, the Provider and Customer also intend that:

1.   Prior to the start of a regulatory project, Regulatory Shared Services will
     develop a mutually agreed-upon workplan with the state regulatory contact.
     Depending upon the scope of the project, the workplan may consist of a
     calendar of events, sources and uses of information, internal and external
     deadlines and the identification of special initiatives or issues. The
     workplan will specify responsibilities and performance measures that have
     been more generically detailed herein.

2.   The successful development, presentation and support of a regulatory filing
     depend upon the availability, timeliness and quality of information
     provided from other functional areas. It is the responsibility of the state
     to either plan and coordinate directly with the other Shared Services units
     for time and resources, or to make arrangements for this information to be
     developed and provided by the state organization.

     service, lack of access to needed information, etc., may result in the

                                 DECLARATION OF
                         PARTNERSHIP PRINCIPLES BETWEEN
             COLUMBIA GAS OF VIRGINIA AND THE SHARED SERVICES CENTER


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Virginia and the Shared Services Center.


PRINCIPLE ONE: This partnership is built on commonality of experience and
               interest.

                  Prior to the formation of the Shared Services Center, services
were provided to the states under the leadership of one CEO. Under this
traditional organizational structure, services were provided to all of the
distribution companies of the Columbia Energy Group. Today, there is greater
operating autonomy among the distribution companies as each pursues unique
marketing opportunities and responds to unique regulatory and economic
conditions. Each company now has the benefit of a dedicated CEO. Nonetheless,
there continues to be commonality of interest and goals between Columbia Gas of
Virginia and the Shared Services Center as both strive:

                  (1)      to promote the brand themes of the Columbia Energy
                           Group, which are:
                           expertise;
                           reliability;
                           value;
                           service; and
                           affiliation with the Columbia Energy Group; and

                  (2)      to promote the financial well-being of Columbia Gas
                           of Virginia and the Columbia Energy Group through
                           maximizing the efficiencies of existing and emerging
                           common systems and practices, while promoting
                           individualized solutions which meet the unique needs
                           of Columbia Gas of Virginia.

PRINCIPLE TWO: This partnership is built on trust and mutual respect.

                  Trust is built upon competence, commonality, and the intent to
serve. Only when there is an anticipated long-term relationship can trust be
developed and maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Virginia and the Shared Services Center commit to the following:

                  (1)      Columbia Gas of Virginia demonstrates a high degree
                           of operational expertise. It is equally important
                           that the staff functions within the Shared


<PAGE>   185

                           Services Center demonstrate and maintain high levels
                           of expertise to support the operational expertise of
                           its company-client.

                  (2)      Columbia Gas of Virginia puts its customers first.
                           The Shared Services Center puts its company-clients
                           first, and is dedicated to providing Columbia Gas of
                           Virginia with a level of service that reflects this
                           philosophy. Therefore, the specific customer service
                           expectations which are shared by Columbia Gas of
                           Virginia and the Shared Services Center, and the
                           associated service metrics, are set forth in the
                           Appendices attached to this Declaration of
                           Principles. Columbia Gas of Virginia and the Shared
                           Services Center anticipate that these service
                           expectations and metrics will tend to remain
                           constant. However, as it becomes necessary or
                           desirable to amend the service expectations or
                           metrics, Columbia Gas of Virginia and the Shared
                           Services Center will do so.

                  (3)      Columbia Gas of Virginia at all times shows its
                           customers the respect they deserve. The Shared
                           Services Center respects both its company-clients and
                           the client's customers. This respect is demonstrated
                           by the level of service provided to its
                           company-client and measured by accomplishing the
                           service metrics agreed upon between itself and the
                           company-client.


PRINCIPLE THREE: A policy of open and frank communication is fundamental to this
                 partnership.

                  Only if there is open, frank and regular communication between
Columbia Gas of Virginia and the Shared Services Center can the partnership
relationship be nurtured and strengthened. Such communications are fundamental
and serve the following goals:

                  (1)      to identify the current and future service needs of
                           Columbia Gas of Virginia;

                  (2)      to identify skill development needs within the Shared
                           Services Center to better serve Columbia Gas of
                           Virginia;

                  (3)      to identify revenue opportunities;

                  (4)      to identify the budgetary support necessary to
                           provide the level of service desired by the
                           client-company;

                  (5)      to provide an opportunity for a quality-check on the
                           level and quality of service; and

                  (6)      to provide an opportunity to redirect resources in
                           response to business environment changes.


                                                                               2
<PAGE>   186

                  To meet these goals, Columbia Gas of Virginia and the Shared
Services Center commit to the following:

                  (1)      To create an environment which encourages and
                           supports open, frank and regular communication;

                  (2)      To have key personnel meet on a mutually satisfactory
                           frequency to discuss service satisfaction and service
                           expectations and needs. The attached appendices
                           include the meeting schedule, which will be amended
                           as it mutually appears to be necessary or desirable
                           to do so.

                  (3)      To work together to meet agreed upon financial and
                           budgetary goals. In support of this goal, the Shared
                           Services Center will provide Columbia Gas of Virginia
                           with a budget report, in a form and at a frequency
                           which is agreed upon. The attached appendices include
                           the budget report, which will be amended as it
                           mutually appears to be necessary or desirable to do
                           so.

                  (4)      To work together to annually redefine the services to
                           be provided and the anticipated cost of those
                           services. This annual redefinition of services and
                           costs must be completed in conjunction with Columbia
                           Gas of Virginia's budgetary process and in compliance
                           with any pricing requirements established by the
                           Public Utility Holding Company Act of 1935, as
                           amended, or other relevant law or regulation. The
                           attached appendices include service definitions which
                           will be amended as it mutually appears to be
                           necessary or desirable to do so.

                  (5)      To work together to provide each other, and other
                           potentially affected company-clients, with sufficient
                           notice of a planned significant change in anticipated
                           service levels to permit staffing and planning
                           adjustments. To ensure that there is sufficient
                           planning opportunity, the party proposing the
                           significant service level change will provide the
                           other with at least six months notice prior to the
                           end of the fiscal year for the then-current
                           appendices. In the event of such a proposed change,
                           Columbia Gas of Virginia and the Shared Services
                           Center will work together to ensure that the
                           transition period necessitated by the proposed change
                           is adequate to deal equitably with affected employees
                           and to continue to meet business needs. The Shared
                           Service Board (which consists of the then-current
                           company-client Presidents) will mutually, and
                           irrevocably, establish the appropriate timing for any
                           such planned change and the equitable cost
                           reallocation or absorption methodology, if any, to be
                           used among the company-clients.


                                                                               3

                  (6)      To ensure that the Principles expressed in this
                           document are communicated and embraced by all who are
                           critical for the successful continuation of a
                           positive and productive partnership, the management

                           expectations and undertakings described herein and in
                           the attached appendices.

</TABLE>


Other Matters

Graphics/Video/Print Services and CGV also intend that prior to the start of the
provisions of any service, the Primary Provider (Manager, Graphics/Print/Video
Services) and Primary Customer (Vice President, Public Affairs) will define
expectations that could include any of the following elements: timeline, cost
limitation, customer responsibilities, timing of status reports, or other
customer needs.

Unless otherwise instructed by CGV, Graphics/Video/Print Services will share job
order results with other Customers to improve efficiency.

Labor/cost estimates in this Plan assume CGV provides job requests according to
lead time schedule of Graphics/Video/Print Services. If these lead times are not
met, incremental costs could be incurred and must be approved by CGV before
completion of job.


                                                                               2

                                 DECLARATION OF
                         PARTNERSHIP PRINCIPLES BETWEEN
             COLUMBIA GAS OF MARYLAND AND THE SHARED SERVICES CENTER


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Maryland and the Shared Services Center.


PRINCIPLE ONE: This partnership is built on commonality of experience and
               interest.

                  Prior to the formation of the Shared Services Center, services
were provided to the states under the leadership of one CEO. Under this
traditional organizational structure, services were provided to all of the
distribution companies of the Columbia Energy Group. Today, there is greater
operating autonomy among the distribution companies as each pursues unique
marketing opportunities and responds to unique regulatory and economic
conditions. Each company now has the benefit of a dedicated CEO. Nonetheless,
there continues to be commonality of interest and goals between Columbia Gas of
Maryland and the Shared Services Center as both strive:

                  (1)      to promote the brand themes of the Columbia Energy
                           Group, which are:
                           expertise;
                           reliability;
                           value;
                           service; and
                           affiliation with the Columbia Energy Group; and

                  (2)      to promote the financial well-being of Columbia Gas
                           of Maryland and the Columbia Energy Group through
                           maximizing the efficiencies of existing and emerging
                           common systems and practices, while promoting
                           individualized solutions which meet the unique needs
                           of Columbia Gas of Maryland.


PRINCIPLE TWO: This partnership is built on trust and mutual respect.

                  Trust is built upon competence, commonality, and the intent to
serve. Only when there is an anticipated long-term relationship can trust be
developed and maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Maryland and the Shared Services Center commit to the following:

                  (1)      Columbia Gas of Maryland demonstrates a high degree
                           of operational expertise. It is equally important
                           that the staff functions within the Shared

<PAGE>   192

                           Services Center demonstrate and maintain high levels
                           of expertise to support the operational expertise of
                           its company-client.

                  (2)      Columbia Gas of Maryland puts its customers first.
                           The Shared Services Center puts its company-clients
                           first, and is dedicated to providing Columbia Gas of
                           Maryland with a level of service that reflects this
                           philosophy. Therefore, the specific customer service
                           expectations which are shared by Columbia Gas of
                           Maryland and the Shared Services Center, and the
                           associated service metrics, are set forth in the
                           Appendices attached to this Declaration of
                           Principles. Columbia Gas of Maryland and the Shared
                           Services Center anticipate that these service
                           expectations and metrics will tend to remain
                           constant. However, as it becomes necessary or
                           desirable to amend the service expectations or
                           metrics, Columbia Gas of Maryland and the Shared
                           Services Center will do so.

                  (3)      Columbia Gas of Maryland at all times shows its
                           customers the respect they deserve. The Shared
                           Services Center respects both its company-clients and
                           the client's customers. This respect is demonstrated
                           by the level of service provided to its
                           company-client and measured by accomplishing the
                           service metrics agreed upon between itself and the
                           company-client.


PRINCIPLE THREE: A policy of open and frank communication is fundamental to this
                 partnership.

                  Only if there is open, frank and regular communication between
Columbia Gas of Maryland and the Shared Services Center can the partnership
relationship be nurtured and strengthened. Such communications are fundamental
and serve the following goals:

                  (1)      to identify the current and future service needs of
                           Columbia Gas of Maryland;

                  (2)      to identify skill development needs within the Shared
                           Services Center to better serve Columbia Gas of
                           Maryland;

                  (3)      to identify revenue opportunities;

                  (4)      to identify the budgetary support necessary to
                           provide the level of service desired by the
                           client-company;

                  (5)      to provide an opportunity for a quality-check on the
                           level and quality of service; and


                                                                               2
<PAGE>   193

                  (6)      to provide an opportunity to redirect resources in
                           response to business environment changes.

                  To meet these goals, Columbia Gas of Maryland and the Shared
Services Center commit to the following:

                  (1)      To create an environment which encourages and
                           supports open, frank and regular communication;

                  (2)      To have key personnel meet on a mutually satisfactory
                           frequency to discuss service satisfaction and service
                           expectations and needs. The attached appendices
                           include the meeting schedule, which will be amended
                           as it mutually appears to be necessary or desirable
                           to do so.

                  (3)      To work together to meet agreed upon financial and
                           budgetary goals. In support of this goal, the Shared
                           Services Center will provide Columbia Gas of Maryland
                           with a budget report, in a form and at a frequency
                           which is agreed upon. The attached appendices include
                           the budget report, which will be amended as it
                           mutually appears to be necessary or desirable to do
                           so.

                  (4)      To work together to annually redefine the services to
                           be provided and the anticipated cost of those
                           services. This annual redefinition of services and
                           costs must be completed in conjunction with Columbia
                           Gas of Maryland's budgetary process and in compliance
                           with any pricing requirements established by the
                           Public Utility Holding Company Act of 1935, as
                           amended, or other relevant law or regulation. The
                           attached appendices include service definitions which
                           will be amended as it mutually appears to be
                           necessary or desirable to do so.

                  (5)      To work together to provide each other, and other
                           potentially affected company-clients, with sufficient
                           notice of a planned significant change in anticipated
                           service levels to permit staffing and planning
                           adjustments. To ensure that there is sufficient
                           planning opportunity, the party proposing the
                           significant service level change will provide the
                           other with at least six months notice prior to the
                           end of the fiscal year for the then-current
                           appendices. In the event of such a proposed change,
                           Columbia Gas of Maryland and the Shared Services
                           Center will work together to ensure that the
                           transition period necessitated by the proposed change
                           is adequate to deal equitably with affected employees
                           and to continue to meet business needs. The Shared
                           Service Board (which consists of the then-current
                           company-client Presidents) will mutually, and
                           irrevocably, establish the appropriate timing for any
                           such planned change and the equitable cost
                           reallocation or absorption methodology, if any, to be
                           used among the company-clients.


                                                                               3
<PAGE>   194

                  (6)      To ensure that the Principles expressed in this
                           document are communicated and embraced by all who are
                           critical for the successful continuation of a
                           positive and productive partnership, the management
                           representatives whose signatures appear below,
                           confirm their commitment to fulfilling the
                           expectations and undertakings described herein and in
                           the attached appendices.

Other Matters

Graphics/Video/Print Services and CMD also intend that prior to the start of the
provisions of any service, the Primary Provider (Manager, Graphics/Print/Video
Services) and Primary Customer (Director, Corporate Communications) will define
expectations that could include any of the following elements: timeline, cost
limitation, customer responsibilities, timing of status reports, or other
customer needs.

Unless otherwise instructed by CMD, Graphics/Video/Print Services will share job
order results with other Customers to improve efficiency.

Labor/cost estimates in this Plan assume CMD provides job requests according to
lead time schedule of Graphics/Video/Print Services. If these lead times are not
met, incremental costs could be incurred and must be approved by CMD before
completion of job.

                                 DECLARATION OF
                         PARTNERSHIP PRINCIPLES BETWEEN
               COLUMBIA GAS OF OHIO AND THE SHARED SERVICES CENTER


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Ohio and the Shared Services Center.


PRINCIPLE ONE: This partnership is built on commonality of experience and
               interest.

                  Prior to the formation of the Shared Services Center, services
were provided to the states under the leadership of one CEO. Under this
traditional organizational structure, services were provided to all of the
distribution companies of the Columbia Energy Group. Today, there is greater
operating autonomy among the distribution companies as each pursues unique
marketing opportunities and responds to unique regulatory and economic
conditions. Each company now has the benefit of a dedicated CEO. Nonetheless,
there continues to be commonality of interest and goals between Columbia Gas of
Ohio and the Shared Services Center as both strive:

                  (1)      to promote the brand themes of the Columbia Energy
                           Group, which are:
                           expertise;
                           reliability;
                           value;
                           service; and
                           affiliation with the Columbia Energy Group; and

                  (2)      to promote the financial well-being of Columbia Gas
                           of Ohio and the Columbia Energy Group through
                           maximizing the efficiencies of existing and emerging
                           common systems and practices, while promoting
                           individualized solutions which meet the unique needs
                           of Columbia Gas of Ohio.


PRINCIPLE TWO: This partnership is built on trust and mutual respect.

                  Trust is built upon competence, commonality, and the intent to
serve. Only when there is an anticipated long-term relationship can trust be
developed and maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Ohio and the Shared Services Center commit to the following:

                  (1)      Columbia Gas of Ohio demonstrates a high degree of
                           operational expertise. It is equally important that
                           the staff functions within the Shared

<PAGE>   199

                           Services Center demonstrate and maintain high levels
                           of expertise to support the operational expertise of
                           its company-client.

                  (2)      Columbia Gas of Ohio puts its customers first. The
                           Shared Services Center puts its company-clients
                           first, and is dedicated to providing Columbia Gas of
                           Ohio with a level of service that reflects this
                           philosophy. Therefore, the specific customer service
                           expectations which are shared by Columbia Gas of Ohio
                           and the Shared Services Center, and the associated
                           service metrics, are set forth in the Appendices
                           attached to this Declaration of Principles. Columbia
                           Gas of Ohio and the Shared Services Center anticipate
                           that these service expectations and metrics will tend
                           to remain constant. However, as it becomes necessary
                           or desirable to amend the service expectations or
                           metrics, Columbia Gas of Ohio and the Shared Services
                           Center will do so.

                  (3)      Columbia Gas of Ohio at all times shows its customers
                           the respect they deserve. The Shared Services Center
                           respects both its company-clients and the client's
                           customers. This respect is demonstrated by the level
                           of service provided to its company-client and
                           measured by accomplishing the service metrics agreed
                           upon between itself and the company-client.


PRINCIPLE THREE: A policy of open and frank communication is fundamental to this
                 partnership.

                  Only if there is open, frank and regular communication between
Columbia Gas of Ohio and the Shared Services Center can the partnership
relationship be nurtured and strengthened. Such communications are fundamental
and serve the following goals:

                  (1)      to identify the current and future service needs of
                           Columbia Gas of Ohio;

                  (2)      to identify skill development needs within the Shared
                           Services Center to better serve Columbia Gas of Ohio;

                  (3)      to identify revenue opportunities;

                  (4)      to identify the budgetary support necessary to
                           provide the level of service desired by the
                           client-company;

                  (5)      to provide an opportunity for a quality-check on the
                           level and quality of service; and

                  (6)      to provide an opportunity to redirect resources in
                           response to business environment changes.


                                                                               2
<PAGE>   200

                  To meet these goals, Columbia Gas of Ohio and the Shared
Services Center commit to the following:

                  (1)      To create an environment which encourages and
                           supports open, frank and regular communication;

                  (2)      To have key personnel meet on a mutually satisfactory
                           frequency to discuss service satisfaction and service
                           expectations and needs. The attached appendices
                           include the meeting schedule, which will be amended
                           as it mutually appears to be necessary or desirable
                           to do so.

                  (3)      To work together to meet agreed upon financial and
                           budgetary goals. In support of this goal, the Shared
                           Services Center will provide Columbia Gas of Ohio
                           with a budget report, in a form and at a frequency
                           which is agreed upon. The attached appendices include
                           the budget report, which will be amended as it
                           mutually appears to be necessary or desirable to do
                           so.

                  (4)      To work together to annually redefine the services to
                           be provided and the anticipated cost of those
                           services. This annual redefinition of services and
                           costs must be completed in conjunction with Columbia
                           Gas of Ohio's budgetary process and in compliance
                           with any pricing requirements established by the
                           Public Utility Holding Company Act of 1935, as
                           amended, or other relevant law or regulation. The
                           attached appendices include service definitions which
                           will be amended as it mutually appears to be
                           necessary or desirable to do so.

                  (5)      To work together to provide each other, and other
                           potentially affected company-clients, with sufficient
                           notice of a planned significant change in anticipated
                           service levels to permit staffing and planning
                           adjustments. To ensure that there is sufficient
                           planning opportunity, the party proposing the
                           significant service level change will provide the
                           other with at least six months notice prior to the
                           end of the fiscal year for the then-current
                           appendices. In the event of such a proposed change,
                           Columbia Gas of Ohio and the Shared Services Center
                           will work together to ensure that the transition
                           period necessitated by the proposed change is
                           adequate to deal equitably with affected employees
                           and to continue to meet business needs. The Shared
                           Service Board (which consists of the then-current
                           company-client Presidents) will mutually, and
                           irrevocably, establish the appropriate timing for any
                           such planned change and the equitable cost
                           reallocation or absorption methodology, if any, to be
                           used among the company-clients.

                  (6)      To ensure that the Principles expressed in this
                           document are communicated and embraced by all who are
                           critical for the successful continuation of a
                           positive and productive partnership, the management


                                                                               3

OTHER MATTERS

Graphics/Video/Print Services and COH also intend that prior to the start of the
provisions of any service, the Primary Provider (Manager, Graphics/Print/Video
Services) and Primary Customer (Vice President of Communications) will define
expectations that could include any of the following elements: timeline, cost
limitation, customer responsibilities, timing of status reports, or other
customer needs.

Unless otherwise instructed by COH, Graphics/Video/Print Services will share job
order results with other Customers to improve efficiency.

Labor/cost estimates in this Plan assume COH provides job requests according to
lead time schedule of Graphics/Video/Print Services. If these lead times are not
met, incremental costs could be incurred and must be approved by COH before
completion of job.


                                                                               2

                                 DECLARATION OF
                         PARTNERSHIP PRINCIPLES BETWEEN
           COLUMBIA GAS OF PENNSYLVANIA AND THE SHARED SERVICES CENTER


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Pennsylvania and the Shared Services
Center.


PRINCIPLE ONE: THIS PARTNERSHIP IS BUILT ON COMMONALITY OF EXPERIENCE AND
               INTEREST.

                  Prior to the formation of the Shared Services Center, services
were provided to the states under the leadership of one CEO. Under this
traditional organizational structure, services were provided to all of the
distribution companies of the Columbia Energy Group. Today, there is greater
operating autonomy among the distribution companies as each pursues unique
marketing opportunities and responds to unique regulatory and economic
conditions. Each company now has the benefit of a dedicated CEO. Nonetheless,
there continues to be commonality of interest and goals between Columbia Gas of
Pennsylvania and the Shared Services Center as both strive:

                  (1)      to promote the brand themes of the Columbia Energy
                           Group, which are:
                           expertise;
                           reliability;
                           value;
                           service; and
                           affiliation with the Columbia Energy Group; and

                  (2)      to promote the financial well-being of Columbia Gas
                           of Pennsylvania and the Columbia Energy Group through
                           maximizing the efficiencies of existing and emerging
                           common systems and practices, while promoting
                           individualized solutions which meet the unique needs
                           of Columbia Gas of Pennsylvania.


PRINCIPLE TWO: THIS PARTNERSHIP IS BUILT ON TRUST AND MUTUAL RESPECT.

                  Trust is built upon competence, commonality, and the intent to
serve. Only when there is an anticipated long-term relationship can trust be
developed and maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Pennsylvania and the Shared Services Center commit to the
following:

                  (1)      Columbia Gas of Pennsylvania demonstrates a high
                           degree of operational expertise. It is equally
                           important that the staff functions within the Shared

<PAGE>   206

                           Services Center demonstrate and maintain high levels
                           of expertise to support the operational expertise of
                           its company-client.

                  (2)      Columbia Gas of Pennsylvania puts its customers
                           first. The Shared Services Center puts its
                           company-clients first, and is dedicated to providing
                           Columbia Gas of Pennsylvania with a level of service
                           that reflects this philosophy. Therefore, the
                           specific customer service expectations which are
                           shared by Columbia Gas of Pennsylvania and the Shared
                           Services Center, and the associated service metrics,
                           are set forth in the Appendices attached to this
                           Declaration of Principles. Columbia Gas of
                           Pennsylvania and the Shared Services Center
                           anticipate that these service expectations and
                           metrics will tend to remain constant. However, as it
                           becomes necessary or desirable to amend the service
                           expectations or metrics, Columbia Gas of Pennsylvania
                           and the Shared Services Center will do so.

                  (3)      Columbia Gas of Pennsylvania at all times shows its
                           customers the respect they deserve. The Shared
                           Services Center respects both its company-clients and
                           the client's customers. This respect is demonstrated
                           by the level of service provided to its
                           company-client and measured by accomplishing the
                           service metrics agreed upon between itself and the
                           company-client.


PRINCIPLE THREE: A POLICY OF OPEN AND FRANK COMMUNICATION IS FUNDAMENTAL TO THIS
                 PARTNERSHIP.

                  Only if there is open, frank and regular communication between
Columbia Gas of Pennsylvania and the Shared Services Center can the partnership
relationship be nurtured and strengthened. Such communications are fundamental
and serve the following goals:

                  (1)      to identify the current and future service needs of
                           Columbia Gas of Pennsylvania;

                  (2)      to identify skill development needs within the Shared
                           Services Center to better serve Columbia Gas of
                           Pennsylvania;

                  (3)      to identify revenue opportunities;

                  (4)      to identify the budgetary support necessary to
                           provide the level of service desired by the
                           client-company;

                  (5)      to provide an opportunity for a quality-check on the
                           level and quality of service; and


                                                                               2
<PAGE>   207

                  (6)      to provide an opportunity to redirect resources in
                           response to business environment changes.

                  To meet these goals, Columbia Gas of Pennsylvania and the
Shared Services Center commit to the following:

                  (1)      To create an environment which encourages and
                           supports open, frank and regular communication;

                  (2)      To have key personnel meet on a mutually satisfactory
                           frequency to discuss service satisfaction and service
                           expectations and needs. The attached appendices
                           include the meeting schedule, which will be amended
                           as it mutually appears to be necessary or desirable
                           to do so.

                  (3)      To work together to meet agreed upon financial and
                           budgetary goals. In support of this goal, the Shared
                           Services Center will provide Columbia Gas of
                           Pennsylvania with a budget report, in a form and at a
                           frequency which is agreed upon. The attached
                           appendices include the budget report, which will be
                           amended as it mutually appears to be necessary or
                           desirable to do so.

                  (4)      To work together to annually redefine the services to
                           be provided and the anticipated cost of those
                           services. This annual redefinition of services and
                           costs must be completed in conjunction with Columbia
                           Gas of Pennsylvania's budgetary process and in
                           compliance with any pricing requirements established
                           by the Public Utility Holding Company Act of 1935, as
                           amended, or other relevant law or regulation. The
                           attached appendices include service definitions which
                           will be amended as it mutually appears to be
                           necessary or desirable to do so.

                  (5)      To work together to provide each other, and other
                           potentially affected company-clients, with sufficient
                           notice of a planned significant change in anticipated
                           service levels to permit staffing and planning
                           adjustments. To ensure that there is sufficient
                           planning opportunity, the party proposing the
                           significant service level change will provide the
                           other with at least six months notice prior to the
                           end of the fiscal year for the then-current
                           appendices. In the event of such a proposed change,
                           Columbia Gas of Pennsylvania and the Shared Services
                           Center will work together to ensure that the
                           transition period necessitated by the proposed change
                           is adequate to deal equitably with affected employees
                           and to continue to meet business needs. The Shared
                           Service Board (which consists of the then-current
                           company-client Presidents) will mutually, and
                           irrevocably, establish the appropriate timing for any
                           such planned change and the equitable cost
                           reallocation or absorption methodology, if any, to be
                           used among the company-clients.


                                                                               3
<PAGE>   208

                  (6)      To ensure that the Principles expressed in this
                           document are communicated and embraced by all who are
                           critical for the successful continuation of a
                           positive and productive partnership, the management
                           representatives whose signatures appear below,
                           confirm their commitment to fulfilling the
                           expectations and undertakings described herein and in
                           the attached appendices.

OTHER MATTERS

Graphics/Video/Print Services and CPA also intend that prior to the start of the
provisions of any service, the Primary Provider (Manager, Graphics/Print/Video
Services) and Primary Customer (Director, Corporate Communications) will define
expectations that could include any of the following elements: timeline, cost
limitation, customer responsibilities, timing of status reports, or other
customer needs.

Unless otherwise instructed by CPA, Graphics/Video/Print Services will share job
order results with other Customers to improve efficiency.

Labor/cost estimates in this Plan assume CPA provides job requests according to
lead time schedule of Graphics/Video/Print Services. If these lead times are not
met, incremental costs could be incurred and must be approved by CPA before
completion of job.

                                 DECLARATION OF
                         PARTNERSHIP PRINCIPLES BETWEEN
             COLUMBIA GAS OF KENTUCKY AND THE SHARED SERVICES CENTER


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Kentucky and the Shared Services Center.


PRINCIPLE ONE: THIS PARTNERSHIP IS BUILT ON COMMONALITY OF EXPERIENCE AND
INTEREST.

                  Prior to the formation of the Shared Services Center, services
were provided to the states under the leadership of one CEO. Under this
traditional organizational structure, services were provided to all of the
distribution companies of the Columbia Energy Group. Today, there is greater
operating autonomy among the distribution companies as each pursues unique
marketing opportunities and responds to unique regulatory and economic
conditions. Each company now has the benefit of a dedicated CEO. Nonetheless,
there continues to be commonality of interest and goals between Columbia Gas of
Kentucky and the Shared Services Center as both strive:

                  (1)      to promote the brand themes of the Columbia Energy
                           Group, which are:

                           expertise;
                           reliability;
                           value;
                           service; and
                           affiliation with the Columbia Energy Group; and

                  (2)      to promote the financial well-being of Columbia Gas
                           of Kentucky and the Columbia Energy Group through
                           maximizing the efficiencies of existing and emerging
                           common systems and practices, while promoting
                           individualized solutions which meet the unique needs
                           of Columbia Gas of Kentucky.


PRINCIPLE TWO:  THIS PARTNERSHIP IS BUILT ON TRUST AND MUTUAL RESPECT.

                  Trust is built upon competence, commonality, and the intent to
serve. Only when there is an anticipated long-term relationship can trust be
developed and maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Kentucky and the Shared Services Center commit to the following:

<PAGE>   213

                  (1)      Columbia Gas of Kentucky demonstrates a high degree
                           of operational expertise. It is equally important
                           that the staff functions within the Shared Services
                           Center demonstrate and maintain high levels of
                           expertise to support the operational expertise of its
                           company-client.

                  (2)      Columbia Gas of Kentucky puts its customers first.
                           The Shared Services Center puts its company-clients
                           first, and is dedicated to providing Columbia Gas of
                           Kentucky with a level of service that reflects this
                           philosophy. Therefore, the specific customer service
                           expectations which are shared by Columbia Gas of
                           Kentucky and the Shared Services Center, and the
                           associated service metrics, are set forth in the
                           Appendices attached to this Declaration of
                           Principles. Columbia Gas of Kentucky and the Shared
                           Services Center anticipate that these service
                           expectations and metrics will tend to remain
                           constant. However, as it becomes necessary or
                           desirable to amend the service expectations or
                           metrics, Columbia Gas of Kentucky and the Shared
                           Services Center will do so.

                  (3)      Columbia Gas of Kentucky at all times shows its
                           customers the respect they deserve. The Shared
                           Services Center respects both its company-clients and
                           the client's customers. This respect is demonstrated
                           by the level of service provided to its
                           company-client and measured by accomplishing the
                           service metrics agreed upon between itself and the
                           company-client.


PRINCIPLE THREE: A POLICY OF OPEN AND FRANK COMMUNICATION IS FUNDAMENTAL TO THIS
PARTNERSHIP.

                  Only if there is open, frank and regular communication between
Columbia Gas of Kentucky and the Shared Services Center can the partnership
relationship be nurtured and strengthened. Such communications are fundamental
and serve the following goals:

                  (1) to identify the current and future service needs of
Columbia Gas of Kentucky;

                  (2) to identify skill development needs within the Shared
Services Center to better serve Columbia Gas of Kentucky;

                  (3) to identify revenue opportunities;

                  (4) to identify the budgetary support necessary to provide the
level of service desired by the client-company;


                                                                               2
<PAGE>   214
                  (5)      to provide an opportunity for a quality-check on the
                           level and quality of service; and

                  (6)      to provide an opportunity to redirect resources in
                           response to business environment changes.

                  To meet these goals, Columbia Gas of Kentucky and the Shared
Services Center commit to the following:

                  (1)      To create an environment which encourages and
                           supports open, frank and regular communication;

                  (2)      To have key personnel meet on a mutually satisfactory
                           frequency to discuss service satisfaction and service
                           expectations and needs. The attached appendices
                           include the meeting schedule, which will be amended
                           as it mutually appears to be necessary or desirable
                           to do so.

                  (3)      To work together to meet agreed upon financial and
                           budgetary goals. In support of this goal, the Shared
                           Services Center will provide Columbia Gas of Kentucky
                           with a budget report, in a form and at a frequency
                           which is agreed upon. The attached appendices include
                           the budget report, which will be amended as it
                           mutually appears to be necessary or desirable to do
                           so.

                  (4)      To work together to annually redefine the services to
                           be provided and the anticipated cost of those
                           services. This annual redefinition of services and
                           costs must be completed in conjunction with Columbia
                           Gas of Kentucky's budgetary process and in compliance
                           with any pricing requirements established by the
                           Public Utility Holding Company Act of 1935, as
                           amended, or other relevant law or regulation. The
                           attached appendices include service definitions which
                           will be amended as it mutually appears to be
                           necessary or desirable to do so.

                  (5)      To work together to provide each other, and other
                           potentially affected company-clients, with sufficient
                           notice of a planned significant change in anticipated
                           service levels to permit staffing and planning
                           adjustments. To ensure that there is sufficient
                           planning opportunity, the party proposing the
                           significant service level change will provide the
                           other with at least six months notice prior to the
                           end of the fiscal year for the then-current
                           appendices. In the event of such a proposed change,
                           Columbia Gas of Kentucky and the Shared Services
                           Center will work together to ensure that the
                           transition period necessitated by the proposed change
                           is adequate to deal equitably with affected employees
                           and to continue to meet business needs. The Shared
                           Service Board (which consists of the

                                                                               3

                           then-current company-client Presidents) will
                           mutually, and irrevocably, establish the appropriate
                           timing for any such planned change and the equitable
                           cost reallocation or absorption methodology, if any,
                           to be used among the company-clients.

                  (6)      To ensure that the Principles expressed in this
                           document are communicated and embraced by all who are
                           critical for the successful continuation of a
                           positive and productive partnership, the management
                           representatives whose signatures appear below,
                           confirm their commitment to fulfilling the
                           expectations and undertakings described herein and in
                           the attached appendices.

OTHER MATTERS

Graphics/Video/Print Services and CKY also intend that prior to the start of the
provisions of any service, the Primary Provider (Manager, Graphics/Print/Video
Services) and Primary Customer (Director, External Affairs) will define
expectations that could include any of the following elements: timeline, cost
limitation, customer responsibilities, timing of status reports, or other
customer needs.

Unless otherwise instructed by CKY, Graphics/Video/Print Services will share job
order results with other Customers to improve efficiency.

Labor/cost estimates in this Plan assume CKY provides job requests according to
lead time schedule of Graphics/Video/Print Services. If these lead times are not
met,


                                                                               3

                             PARTNERSHIP PRINCIPLES
                                     between
               COLUMBIA GAS OF VIRGINIA and SHARED LEGAL SERVICES


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Virginia and Shared Legal Services. This
Declaration is expected to remain in place an indefinite period of time. If and
when either party determines it is desirable or necessary to alter the
provisions contained in the Declaration's Appendices, they pledge to work
cooperatively to bring about such alterations.

PRINCIPLE ONE: This partnership is built on commonality of experience and
interest.

         Prior to the formation of the Shared Services Center, a legal
department under the leadership of one General Counsel provided legal support
services. Under this organizational structure, legal services were provided to
all of the distribution companies of the Columbia Energy Group. Today, as each
company pursues unique marketing opportunities and responds to unique regulatory
and economic conditions, there is greater operating autonomy among the
companies. Each company's legal function is led by its own General Counsel and
served in part by state staff attorneys. Nonetheless, there continues to be
commonality of interest and goals between Columbia Gas of Virginia and Shared
Legal Services, as both strive:

         (1)      To promote the brand themes of the Columbia Energy Group,
                  which are:
                  expertise;
                  reliability;
                  value;
                  service; and

                  Affiliation with the Columbia Energy Group; and

         (2)      To promote the financial well-being of Columbia Gas of
                  Virginia and The Columbia Energy Group through maximizing the
                  efficiencies of existing and emerging common systems and
                  practices, while promoting individualized solutions which meet
                  the unique needs of Columbia Gas of Virginia.

PRINCIPLE TWO: This partnership is built on trust and mutual respect.

         Trust is built upon competence, commonality, and the intent to serve.
Only when there is an anticipated long-term relationship can trust be developed
and be maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Virginia and Shared Legal Services commit to the following:


                                                                               1
<PAGE>   221
         (1)      Columbia Gas of Virginia demonstrates a high degree of
                  operational expertise. It is equally important that the staff
                  functions within Shared Legal Services demonstrate and
                  maintain high levels of expertise to support the operational
                  expertise of its company-client.

         (2)      Columbia Gas of Virginia puts its customers first. Shared
                  Legal Services puts its company-clients first, and is
                  dedicated to providing Columbia Gas of Virginia with a level
                  of service that reflects this philosophy. Therefore, the
                  specific customer service expectations which are shared by
                  Columbia Gas of Virginia and Shared Legal Services, and the
                  associated service metrics, are set forth in Appendix A and
                  attached to this Declaration of Principles. Columbia Gas of
                  Virginia and Shared Legal Services anticipate that these
                  service expectations and metrics will tend to remain constant.
                  However, as it becomes necessary or desirable to amend the
                  service expectations or metrics, Columbia Gas of Virginia and
                  Shared Legal Services will do so.

         (3)      Columbia Gas of Virginia at all times shows its customers the
                  respect they deserve. Shared Legal Services respects both its
                  company-clients and the client's customers. This respect is
                  demonstrated by the level of service provided to its
                  company-client and measured by accomplishing the service
                  metrics agreed upon between itself and the company-client.

PRINCIPLE THREE: A policy of open and frank communication is fundamental to this
partnership.

         Only if there is open, frank and regular communication between Columbia
Gas of Virginia and Shared Legal Services can the partnership relationship be
nurtured and strengthened. Such communications are fundamental and serve the
following goals:

         (1)      to identify the current and future service needs of Columbia
                  Gas of Virginia;

         (2)      to identify skill development needs within Shared Legal
                  Services to better serve Columbia Gas of Virginia;

         (3)      to identify revenue opportunities;

         (4)      to identify the budgetary support necessary to provide the
                  level of service desired by the client-company;

         (5)      to provide an opportunity for a quality-check on the level and
                  quality of service; and

         (6)      To provide an opportunity to redirect resources in response to
                  business environment changes.

         To meet these goals, Columbia Gas of Virginia and Shared Legal Services
commit to the following:

         (1)      To create an environment within their respective organizations
                  which encourages and supports open, frank and regular
                  communication.

         (2)      To have the General Counsel and the Manager of Shared Legal
                  Services meet on a mutually satisfactory frequency to discuss
                  service satisfaction and service

                                                                               2
<PAGE>   222
                  expectations and needs. Attached as Appendix B is the proposed
                  meeting schedule, which will be amended, as it mutually
                  appears to be necessary or desirable to do so.

         (1)      To work together to annually redefine the services to be
                  provided and the anticipated cost of those services. This
                  annual redefinition of services and costs must be completed in
                  conjunction with Columbia Gas of Virginia's budgetary process
                  and in compliance with any pricing requirements established by
                  the Public Utility Holding Company Act of 1935, as amended, or
                  other relevant law or regulation. Attached as Appendix C is
                  the form of annual service definition and budgetary
                  projection, which will be amended as it mutually appears to be
                  necessary or desirable to do so.

         (2)      To work together to provide each other and other potentially
                  affected company-clients, with sufficient notice of a planned
                  significant change in anticipated service levels to permit
                  staffing and planning adjustments. To ensure that there is
                  sufficient planning opportunity, the party proposing the
                  significant service level change will provide the other with
                  at least six months notice prior to the end of the fiscal year
                  for the then-current Appendix C. In the event of such a
                  proposed change, Columbia Gas of Virginia and Shared Legal
                  Services will work together to ensure that the transition
                  period necessitated by the proposed change is adequate to deal
                  equitably with affected employees and to continue to meet
                  business needs. The Shared Service Board (which consists of
                  the then-current company-client Presidents) will mutually, and
                  irrevocably, establish the appropriate timing for any such
                  planned change and the equitable cost reallocation or
                  absorption methodology, if any, to be used among the
                  company-clients.

         (3)      To ensure that the Principles expressed in this document are
                  communicated and embraced by all who are critical for the
                  successful continuation of a positive and productive
                  partnership, the management representatives whose signatures
                  appear below, confirm their commitment to fulfilling the
                  expectations and undertakings described herein and in the
                  attached Appendices.

APPENDIX A

SERVICE METRICS

KEY PERFORMANCE MEASURES
There are three types of measures: Cost (C), Quality (Q) or Time (T).

Cost Measures:

1.       Achieve annual budget projection for CGV.

         Threshold goal - meet budget projection
         Target goal - under budget by 2% on non-labor costs
         Stretch goal - under budget by 4% on non-labor costs

                    Unusual variations in work requests, frequency, etc. will be
communicated to CGV as promptly as possible and SLS and the CGV General Counsel
will discuss and modify expectations, as appropriate.

2.       On an as-requested basis (but no more frequently than annually) provide
         a comparison of SLS labor costs to market rates for substantially
         similar legal services.

         Acceptable - if at or below the cost of an alternative provider
         Excellent - if less than 90% of the alternative provider's costs
         Unacceptable - if exceed alternative provider's costs


Quality and Timeliness Measures:

Prepare and provide CGV an annual customer survey that will measure (1)
timeliness of response, (2) work quality, and (3) communications and achieve
satisfactory service ratings in all three measured categories. Satisfactory
service ratings are defined as SLS having met or exceeded the customers'
expectations as outlined below:

                             PARTNERSHIP PRINCIPLES
                                     between
               COLUMBIA GAS OF KENTUCKY and SHARED LEGAL SERVICES


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Kentucky and Shared Legal Services. This
Declaration is expected to remain in place an indefinite period of time. If and
when either party determines it is desirable or necessary to alter the
provisions contained in the Declaration's Appendices, they pledge to work
cooperatively to bring about such alterations.

PRINCIPLE ONE: This partnership is built on commonality of experience and
interest.

                  Prior to the formation of the Shared Services Center, a legal
department under the leadership of one General Counsel provided legal support
services. Under this organizational structure, legal services were provided to
all of the distribution companies of the Columbia Energy Group. Today, as each
company pursues unique marketing opportunities and responds to unique regulatory
and economic conditions, there is greater operating autonomy among the
companies. Each company's legal function is led by its own General Counsel and
served in part by state staff attorneys. Nonetheless, there continues to be
commonality of interest and goals between Columbia Gas of Kentucky and Shared
Legal Services, as both strive:

         (1)      To promote the brand themes of the Columbia Energy Group,
                  which are:

                  expertise;
                  reliability;
                  value;
                  service; and
                  Affiliation with the Columbia Energy Group; and

         (2)      To promote the financial well-being of Columbia Gas of
                  Kentucky and The Columbia Energy Group through maximizing the
                  efficiencies of existing and emerging common systems and
                  practices, while promoting individualized solutions which meet
                  the unique needs of Columbia Gas of Kentucky.

PRINCIPLE TWO: This partnership is built on trust and mutual respect.

         Trust is built upon competence, commonality, and the intent to serve.
Only when there is an anticipated long-term relationship can trust be developed
and be maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Kentucky and Shared Legal Services commit to the following:

                                                                               1
<PAGE>   229
         (1)      Columbia Gas of Kentucky demonstrates a high degree of
                  operational expertise. It is equally important that the staff
                  functions within Shared Legal Services demonstrate and
                  maintain high levels of expertise to support the operational
                  expertise of its company-client.

         (2)      Columbia Gas of Kentucky puts its customers first. Shared
                  Legal Services puts its company-clients first, and is
                  dedicated to providing Columbia Gas of Kentucky with a level
                  of service that reflects this philosophy. Therefore, the
                  specific customer service expectations which are shared by
                  Columbia Gas of Kentucky and Shared Legal Services, and the
                  associated service metrics, are set forth in Appendix A and
                  attached to this Declaration of Principles. Columbia Gas of
                  Kentucky and Shared Legal Services anticipate that these
                  service expectations and metrics will tend to remain constant.
                  However, as it becomes necessary or desirable to amend the
                  service expectations or metrics, Columbia Gas of Kentucky and
                  Shared Legal Services will do so.

         (3)      Columbia Gas of Kentucky at all times shows its customers the
                  respect they deserve. Shared Legal Services respects both its
                  company-clients and the client's customers. This respect is
                  demonstrated by the level of service provided to its
                  company-client and measured by accomplishing the service
                  metrics agreed upon between itself and the company-client.

PRINCIPLE THREE: A policy of open and frank communication is fundamental to this
partnership.

         Only if there is open, frank and regular communication between Columbia
Gas of Kentucky and Shared Legal Services can the partnership relationship be
nurtured and strengthened. Such communications are fundamental and serve the
following goals:

         (1)      to identify the current and future service needs of Columbia
                  Gas of Kentucky;

         (2)      to identify skill development needs within Shared Legal
                  Services to better serve Columbia Gas of Kentucky;

         (3)      to identify revenue opportunities;

         (4)      to identify the budgetary support necessary to provide the
                  level of service desired by the client-company;

         (5)      to provide an opportunity for a quality-check on the level and
                  quality of service; and

         (6)      To provide an opportunity to redirect resources in response to
                  business environment changes.

         To meet these goals, Columbia Gas of Kentucky and Shared Legal Services
commit to the following:

         (1)      To create an environment within their respective organizations
                  which encourages and supports open, frank and regular
                  communication.

         (2)      To have the General Counsel and the Manager of Shared Legal
                  Services meet on a mutually satisfactory frequency to discuss
                  service satisfaction and service

                                                                               2
<PAGE>   230
                  expectations and needs. Attached as Appendix B is the proposed
                  meeting schedule, which will be amended, as it mutually
                  appears to be necessary or desirable to do so.

         (1)      To work together to annually redefine the services to be
                  provided and the anticipated cost of those services. This
                  annual redefinition of services and costs must be completed in
                  conjunction with Columbia Gas of Kentucky's budgetary process
                  and in compliance with any pricing requirements established by
                  the Public Utility Holding Company Act of 1935, as amended, or
                  other relevant law or regulation. Attached as Appendix C is
                  the form of annual service definition and budgetary
                  projection, which will be amended as it mutually appears to be
                  necessary or desirable to do so.

         (2)      To work together to provide each other and other potentially
                  affected company-clients, with sufficient notice of a planned
                  significant change in anticipated service levels to permit
                  staffing and planning adjustments. To ensure that there is
                  sufficient planning opportunity, the party proposing the
                  significant service level change will provide the other with
                  at least six months notice prior to the end of the fiscal year
                  for the then-current Appendix C. In the event of such a
                  proposed change, Columbia Gas of Kentucky and Shared Legal
                  Services will work together to ensure that the transition
                  period necessitated by the proposed change is adequate to deal
                  equitably with affected employees and to continue to meet
                  business needs. The Shared Service Board (which consists of
                  the then-current company-client Presidents) will mutually, and
                  irrevocably, establish the appropriate timing for any such
                  planned change and the equitable cost reallocation or
                  absorption methodology, if any, to be used among the
                  company-clients.

         (3)      To ensure that the Principles expressed in this document are
                  communicated and embraced by all who are critical for the
                  successful continuation of a positive and productive
                  partnership, the management representatives whose signatures
                  appear below, confirm their commitment to fulfilling the
                  expectations and undertakings described herein and in the
                  attached Appendices.

APPENDIX A

SERVICE METRICS

KEY PERFORMANCE MEASURES
There are three types of measures: Cost (C), Quality (Q) or Time (T).

Cost Measures:

1. Achieve annual budget projection for CKY.

                  Threshold goal - meet budget projection
                  Target goal - under budget by 2% on non-labor costs
                  Stretch goal - under budget by 4% on non-labor costs

                  Unusual variations in work requests, frequency, etc. will be
communicated to CKY as promptly as possible and SLS and the CKY General Counsel
will discuss and modify expectations, as appropriate.

2. On an as-requested basis (but no more frequently than annually) provide a
comparison of SLS labor costs to market rates for substantially similar legal
services.

                  Acceptable - if at or below the cost of an alternative
                  provider
                  Excellent - if less than 90% of the alternative provider's
                  costs
                  Unacceptable - if exceed alternative provider's costs


Quality and Timeliness Measures:

Prepare and provide CKY an annual customer survey that will measure (1)
timeliness of response, (2) work quality, and (3) communications and achieve
satisfactory service ratings in all three measured categories. Satisfactory
service ratings are defined as SLS having met or exceeded the customers'
expectations as outlined below:

                                 DECLARATION OF
                             PARTNERSHIP PRINCIPLES
                                     between
               COLUMBIA GAS OF MARYLAND and SHARED LEGAL SERVICES


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Maryland and Shared Legal Services. This
Declaration is expected to remain in place an indefinite period of time. If and
when either party determines it is desirable or necessary to alter the
provisions contained in the Declaration's Appendices, they pledge to work
cooperatively to bring about such alterations.

PRINCIPLE ONE: This partnership is built on commonality of experience and
interest.

         Prior to the formation of the Shared Services Center, a legal
department under the leadership of one General Counsel provided legal support
services. Under this organizational structure, legal services were provided to
all of the distribution companies of the Columbia Energy Group. Today, as each
company pursues unique marketing opportunities and responds to unique regulatory
and economic conditions, there is greater operating autonomy among the
companies. Each company's legal function is led by its own General Counsel and
served in part by state staff attorneys. Nonetheless, there continues to be
commonality of interest and goals between Columbia Gas of Maryland and Shared
Legal Services, as both strive:

         (1)      To promote the brand themes of the Columbia Energy Group,
                  which are:
                      expertise;
                      reliability;
                      value;
                      service; and
                      Affiliation with the Columbia Energy Group; and

         (2)      To promote the financial well-being of Columbia Gas of
                  Maryland and The Columbia Energy Group through maximizing the
                  efficiencies of existing and emerging common systems and
                  practices, while promoting individualized solutions which meet
                  the unique needs of Columbia Gas of Maryland.

PRINCIPLE TWO: This partnership is built on trust and mutual respect.

         Trust is built upon competence, commonality, and the intent to serve.
Only when there is an anticipated long-term relationship can trust be developed
and be maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Maryland and Shared Legal Services commit to the following:

                                                                               1
<PAGE>   237
         (1)      Columbia Gas of Maryland demonstrates a high degree of
                  operational expertise. It is equally important that the staff
                  functions within Shared Legal Services demonstrate and
                  maintain high levels of expertise to support the operational
                  expertise of its company-client.

         (2)      Columbia Gas of Maryland puts its customers first. Shared
                  Legal Services puts its company-clients first, and is
                  dedicated to providing Columbia Gas of Maryland with a level
                  of service that reflects this philosophy. Therefore, the
                  specific customer service expectations which are shared by
                  Columbia Gas of Maryland and Shared Legal Services, and the
                  associated service metrics, are set forth in Appendix A and
                  attached to this Declaration of Principles. Columbia Gas of
                  Maryland and Shared Legal Services anticipate that these
                  service expectations and metrics will tend to remain constant.
                  However, as it becomes necessary or desirable to amend the
                  service expectations or metrics, Columbia Gas of Maryland and
                  Shared Legal Services will do so.

         (3)      Columbia Gas of Maryland at all times shows its customers the
                  respect they deserve. Shared Legal Services respects both its
                  company-clients and the client's customers. This respect is
                  demonstrated by the level of service provided to its
                  company-client and measured by accomplishing the service
                  metrics agreed upon between itself and the company-client.

PRINCIPLE THREE: A policy of open and frank communication is fundamental to this
partnership.

         Only if there is open, frank and regular communication between Columbia
Gas of Maryland and Shared Legal Services can the partnership relationship be
nurtured and strengthened. Such communications are fundamental and serve the
following goals:

         (1)      to identify the current and future service needs of Columbia
                  Gas of Maryland;

         (2)      to identify skill development needs within Shared Legal
                  Services to better serve Columbia Gas of Maryland;

         (3)      to identify revenue opportunities;

         (4)      to identify the budgetary support necessary to provide the
                  level of service desired by the client-company;

         (5)      to provide an opportunity for a quality-check on the level and
                  quality of service; and

         (6)      To provide an opportunity to redirect resources in response to
                  business environment changes.

         To meet these goals, Columbia Gas of Maryland and Shared Legal Services
commit to the following:

         (1)      To create an environment within their respective organizations
                  which encourages and supports open, frank and regular
                  communication.

         (2)      To have the General Counsel and the Manager of Shared Legal
                  Services meet on a mutually satisfactory frequency to discuss
                  service satisfaction and service

                                                                               2
<PAGE>   238
                  expectations and needs. Attached as Appendix B is the proposed
                  meeting schedule, which will be amended, as it mutually
                  appears to be necessary or desirable to do so.

         (1)      To work together to annually redefine the services to be
                  provided and the anticipated cost of those services. This
                  annual redefinition of services and costs must be completed in
                  conjunction with Columbia Gas of Maryland's budgetary process
                  and in compliance with any pricing requirements established by
                  the Public Utility Holding Company Act of 1935, as amended, or
                  other relevant law or regulation. Attached as Appendix C is
                  the form of annual service definition and budgetary
                  projection, which will be amended as it mutually appears to be
                  necessary or desirable to do so.

         (2)      To work together to provide each other and other potentially
                  affected company-clients, with sufficient notice of a planned
                  significant change in anticipated service levels to permit
                  staffing and planning adjustments. To ensure that there is
                  sufficient planning opportunity, the party proposing the
                  significant service level change will provide the other with
                  at least six months notice prior to the end of the fiscal year
                  for the then-current Appendix C. In the event of such a
                  proposed change, Columbia Gas of Maryland and Shared Legal
                  Services will work together to ensure that the transition
                  period necessitated by the proposed change is adequate to deal
                  equitably with affected employees and to continue to meet
                  business needs. The Shared Service Board (which consists of
                  the then-current company-client Presidents) will mutually, and
                  irrevocably, establish the appropriate timing for any such
                  planned change and the equitable cost reallocation or
                  absorption methodology, if any, to be used among the
                  company-clients.

         (3)      To ensure that the Principles expressed in this document are
                  communicated and embraced by all who are critical for the
                  successful continuation of a positive and productive
                  partnership, the management representatives whose signatures
                  appear below, confirm their commitment to fulfilling the
                  expectations and undertakings described herein and in the
                  attached Appendices.

SERVICE METRICS

KEY PERFORMANCE MEASURES
There are three types of measures: Cost (C), Quality (Q) or Time (T).

Cost Measures:

1. Achieve annual budget projection for CMD.
         Threshold goal - meet budget projection
         Target goal - under budget by 2% on non-labor costs
         Stretch goal - under budget by 4% on non-labor costs

                    Unusual variations in work requests, frequency, etc. will be
communicated to CMD as promptly as possible and SLS and the CMD General Counsel
will discuss and modify expectations, as appropriate.

2. On an as-requested basis (but no more frequently than annually) provide a
comparison of SLS labor costs to market rates for substantially similar legal
services.

         Acceptable - if at or below the cost of an alternative provider
         Excellent - if less than 90% of the alternative provider's costs
         Unacceptable - if exceed alternative provider's costs


Quality and Timeliness Measures:

Prepare and provide CMD an annual customer survey that will measure (1)
timeliness of response, (2) work quality, and (3) communications and achieve
satisfactory service ratings in all three measured categories. Satisfactory
service ratings are defined as SLS having met or exceeded the customers'
expectations as outlined below:

                                 DECLARATION OF
                             PARTNERSHIP PRINCIPLES
                                     between
                 COLUMBIA GAS OF OHIO and SHARED LEGAL SERVICES


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Ohio and Shared Legal Services. This
Declaration is expected to remain in place an indefinite period of time. If and
when either party determines it is desirable or necessary to alter the
provisions contained in the Declaration's Appendices, they pledge to work
cooperatively to bring about such alterations.

PRINCIPLE ONE: This partnership is built on commonality of experience and
interest.

         Prior to the formation of the Shared Services Center, a legal
department under the leadership of one General Counsel provided legal support
services. Under this organizational structure, legal services were provided to
all of the distribution companies of the Columbia Energy Group. Today, as each
company pursues unique marketing opportunities and responds to unique regulatory
and economic conditions, there is greater operating autonomy among the
companies. Each company's legal function is led by its own General Counsel and
served in part by state staff attorneys. Nonetheless, there continues to be
commonality of interest and goals between Columbia Gas of Ohio and Shared Legal
Services, as both strive:

         (1)      To promote the brand themes of the Columbia Energy Group,
                  which are:
                      expertise;
                      reliability;
                      value;
                      service; and
                      Affiliation with the Columbia Energy Group; and

         (2)      To promote the financial well-being of Columbia Gas of Ohio
                  and The Columbia Energy Group through maximizing the
                  efficiencies of existing and emerging common systems and
                  practices, while promoting individualized solutions which meet
                  the unique needs of Columbia Gas of Ohio.

PRINCIPLE TWO: This partnership is built on trust and mutual respect.

         Trust is built upon competence, commonality, and the intent to serve.
Only when there is an anticipated long-term relationship can trust be developed
and be maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Ohio and Shared Legal Services commit to the following:

         (1)      Columbia Gas of Ohio demonstrates a high degree of operational
                  expertise. It is equally important that the staff functions
                  within Shared Legal Services

                                                                               1
<PAGE>   245
                  demonstrate and maintain high levels of expertise to support
                  the operational expertise of its company-client.

         (2)      Columbia Gas of Ohio puts its customers first. Shared Legal
                  Services puts its company-clients first, and is dedicated to
                  providing Columbia Gas of Ohio with a level of service that
                  reflects this philosophy. Therefore, the specific customer
                  service expectations which are shared by Columbia Gas of Ohio
                  and Shared Legal Services, and the associated service metrics,
                  are set forth in Appendix A and attached to this Declaration
                  of Principles. Columbia Gas of Ohio and Shared Legal Services
                  anticipate that these service expectations and metrics will
                  tend to remain constant. However, as it becomes necessary or
                  desirable to amend the service expectations or metrics,
                  Columbia Gas of Ohio and Shared Legal Services will do so.

         (3)      Columbia Gas of Ohio at all times shows its customers the
                  respect they deserve. Shared Legal Services respects both its
                  company-clients and the client's customers. This respect is
                  demonstrated by the level of service provided to its
                  company-client and measured by accomplishing the service
                  metrics agreed upon between itself and the company-client.

PRINCIPLE THREE: A policy of open and frank communication is fundamental to this
partnership.

         Only if there is open, frank and regular communication between Columbia
Gas of Ohio and Shared Legal Services can the partnership relationship be
nurtured and strengthened. Such communications are fundamental and serve the
following goals:

         (1)      to identify the current and future service needs of Columbia
                  Gas of Ohio;

         (2)      to identify skill development needs within Shared Legal
                  Services to better serve Columbia Gas of Ohio;

         (3)      to identify revenue opportunities;

         (4)      to identify the budgetary support necessary to provide the
                  level of service desired by the client-company;

         (5)      to provide an opportunity for a quality-check on the level and
                  quality of service; and

         (6)      To provide an opportunity to redirect resources in response to
                  business environment changes.

         To meet these goals, Columbia Gas of Ohio and Shared Legal Services
commit to the following:

         (1)      To create an environment within their respective organizations
                  which encourages and supports open, frank and regular
                  communication.

         (2)      To have the General Counsel and the Manager of Shared Legal
                  Services meet on a mutually satisfactory frequency to discuss
                  service satisfaction and service expectations and needs.
                  Attached as Appendix B is the proposed meeting


                                                                               2
<PAGE>   246
                  schedule, which will be amended, as it mutually appears to be
                  necessary or desirable to do so.

         (1)      To work together to annually redefine the services to be
                  provided and the anticipated cost of those services. This
                  annual redefinition of services and costs must be completed in
                  conjunction with Columbia Gas of Ohio's budgetary process and
                  in compliance with any pricing requirements established by the
                  Public Utility Holding Company Act of 1935, as amended, or
                  other relevant law or regulation. Attached as Appendix C is
                  the form of annual service definition and budgetary
                  projection, which will be amended as it mutually appears to be
                  necessary or desirable to do so.

         (2)      To work together to provide each other and other potentially
                  affected company-clients, with sufficient notice of a planned
                  significant change in anticipated service levels to permit
                  staffing and planning adjustments. To ensure that there is
                  sufficient planning opportunity, the party proposing the
                  significant service level change will provide the other with
                  at least six months notice prior to the end of the fiscal year
                  for the then-current Appendix C. In the event of such a
                  proposed change, Columbia Gas of Ohio and Shared Legal
                  Services will work together to ensure that the transition
                  period necessitated by the proposed change is adequate to deal
                  equitably with affected employees and to continue to meet
                  business needs. The Shared Service Board (which consists of
                  the then-current company-client Presidents) will mutually, and
                  irrevocably, establish the appropriate timing for any such
                  planned change and the equitable cost reallocation or
                  absorption methodology, if any, to be used among the
                  company-clients.

         (3)      To ensure that the Principles expressed in this document are
                  communicated and embraced by all who are critical for the
                  successful continuation of a positive and productive
                  partnership, the management representatives whose signatures
                  appear below, confirm their commitment to fulfilling the
                  expectations and undertakings described herein and in the
                  attached Appendices.

SERVICE METRICS

KEY PERFORMANCE MEASURES
There are three types of measures: Cost (C), Quality (Q) or Time (T).

Cost Measures:

1. Achieve annual budget projection for COH.
         Threshold goal - meet budget projection
         Target goal - under budget by 2% on non-labor costs
         Stretch goal - under budget by 4% on non-labor costs

         Unusual variations in work requests, frequency, etc. will be
communicated to COH as promptly as possible and SLS and the COH General Counsel
will discuss and modify expectations, as appropriate.

2. On an as-requested basis (but no more frequently than annually) provide a
comparison of SLS labor costs to market rates for substantially similar legal
services.

         Acceptable - if at or below the cost of an alternative provider
         Excellent - if less than 90% of the alternative provider's costs
         Unacceptable - if exceed alternative provider's costs


Quality and Timeliness Measures:

Prepare and provide COH an annual customer survey that will measure (1)
timeliness of response, (2) work quality, and (3) communications and achieve
satisfactory service ratings in all three measured categories. Satisfactory
service ratings are defined as SLS having met or exceeded the customers'
expectations as outlined below:

BUDGETED SERVICE COSTS - 1999

This table summarizes the projected direct annual cost for each service.
"Projected Direct" costs includes hourly labor rates, computer-related charges
and out-of-pocket expenses projected for 1999 by service. "Indirect costs" are a
proportionate share of the costs that are incurred to support all services, such
as building costs, labor benefits, and the expenses of administering the Shared
Services Center. Overhead costs are not specifically identified on the
Customer's books as associated with individual services. The "total cost of
service" is the sum of the Direct and the Overhead costs.

                                 DECLARATION OF
                             PARTNERSHIP PRINCIPLES
                                     between
             COLUMBIA GAS OF PENNSYLVANIA and SHARED LEGAL SERVICES


                  This document outlines the partnership principles which are
the philosophical underpinnings of the relationship, and which govern all
transactions, between Columbia Gas of Pennsylvania and Shared Legal Services.
This Declaration is expected to remain in place an indefinite period of time. If
and when either party determines it is desirable or necessary to alter the
provisions contained in the Declaration's Appendices, they pledge to work
cooperatively to bring about such alterations.

PRINCIPLE ONE: This partnership is built on commonality of experience and
interest.

         Prior to the formation of the Shared Services Center, a legal
department under the leadership of one General Counsel provided legal support
services. Under this organizational structure, legal services were provided to
all of the distribution companies of the Columbia Energy Group. Today, as each
company pursues unique marketing opportunities and responds to unique regulatory
and economic conditions, there is greater operating autonomy among the
companies. Each company's legal function is led by its own General Counsel and
served in part by state staff attorneys. Nonetheless, there continues to be
commonality of interest and goals between Columbia Gas of Pennsylvania and
Shared Legal Services, as both strive:

         (1)      To promote the brand themes of the Columbia Energy Group,
                  which are:
                    expertise;
                    reliability;
                    value;
                    service; and
                    Affiliation with the Columbia Energy Group; and

         (2)      To promote the financial well-being of Columbia Gas of
                  Pennsylvania and The Columbia Energy Group through maximizing
                  the efficiencies of existing and emerging common systems and
                  practices, while promoting individualized solutions which meet
                  the unique needs of Columbia Gas of Pennsylvania.

PRINCIPLE TWO: This partnership is built on trust and mutual respect.

         Trust is built upon competence, commonality, and the intent to serve.
Only when there is an anticipated long-term relationship can trust be developed
and be maintained. Trust also depends upon mutual respect being felt and
demonstrated in the routine business interaction between people. Therefore, both
Columbia Gas of Pennsylvania and Shared Legal Services commit to the following:

                                                                               1
<PAGE>   253
         (1)      Columbia Gas of Pennsylvania demonstrates a high degree of
                  operational expertise. It is equally important that the staff
                  functions within Shared Legal Services demonstrate and
                  maintain high levels of expertise to support the operational
                  expertise of its company-client.

         (2)      Columbia Gas of Pennsylvania puts its customers first. Shared
                  Legal Services puts its company-clients first, and is
                  dedicated to providing Columbia Gas of Pennsylvania with a
                  level of service that reflects this philosophy. Therefore, the
                  specific customer service expectations which are shared by
                  Columbia Gas of Pennsylvania and Shared Legal Services, and
                  the associated service metrics, are set forth in Appendix A
                  and attached to this Declaration of Principles. Columbia Gas
                  of Pennsylvania and Shared Legal Services anticipate that
                  these service expectations and metrics will tend to remain
                  constant. However, as it becomes necessary or desirable to
                  amend the service expectations or metrics, Columbia Gas of
                  Pennsylvania and Shared Legal Services will do so.

         (3)      Columbia Gas of Pennsylvania at all times shows its customers
                  the respect they deserve. Shared Legal Services respects both
                  its company-clients and the client's customers. This respect
                  is demonstrated by the level of service provided to its
                  company-client and measured by accomplishing the service
                  metrics agreed upon between itself and the company-client.

PRINCIPLE THREE: A policy of open and frank communication is fundamental to this
partnership.

         Only if there is open, frank and regular communication between Columbia
Gas of Pennsylvania and Shared Legal Services can the partnership relationship
be nurtured and strengthened. Such communications are fundamental and serve the
following goals:

         (1)      to identify the current and future service needs of Columbia
                  Gas of Pennsylvania;

         (2)      to identify skill development needs within Shared Legal
                  Services to better serve Columbia Gas of Pennsylvania;

         (3)      to identify revenue opportunities;

         (4)      to identify the budgetary support necessary to provide the
                  level of service desired by the client-company;

         (5)      to provide an opportunity for a quality-check on the level and
                  quality of service; and

         (6)      To provide an opportunity to redirect resources in response to
                  business environment changes.

         To meet these goals, Columbia Gas of Pennsylvania and Shared Legal
Services commit to the following:

         (1)      To create an environment within their respective organizations
                  which encourages and supports open, frank and regular
                  communication.

                                                                               2
<PAGE>   254
         (2)      To have the General Counsel and the Manager of Shared Legal
                  Services meet on a mutually satisfactory frequency to discuss
                  service satisfaction and service expectations and needs.
                  Attached as Appendix B is the proposed meeting schedule, which
                  will be amended, as it mutually appears to be necessary or
                  desirable to do so.

         (1)      To work together to annually redefine the services to be
                  provided and the anticipated cost of those services. This
                  annual redefinition of services and costs must be completed in
                  conjunction with Columbia Gas of Pennsylvania's budgetary
                  process and in compliance with any pricing requirements
                  established by the Public Utility Holding Company Act of 1935,
                  as amended, or other relevant law or regulation. Attached as
                  Appendix C is the form of annual service definition and
                  budgetary projection, which will be amended as it mutually
                  appears to be necessary or desirable to do so.

         (2)      To work together to provide each other and other potentially
                  affected company-clients, with sufficient notice of a planned
                  significant change in anticipated service levels to permit
                  staffing and planning adjustments. To ensure that there is
                  sufficient planning opportunity, the party proposing the
                  significant service level change will provide the other with
                  at least six months notice prior to the end of the fiscal year
                  for the then-current Appendix C. In the event of such a
                  proposed change, Columbia Gas of Pennsylvania and Shared Legal
                  Services will work together to ensure that the transition
                  period necessitated by the proposed change is adequate to deal
                  equitably with affected employees and to continue to meet
                  business needs. The Shared Service Board (which consists of
                  the then-current company-client Presidents) will mutually, and
                  irrevocably, establish the appropriate timing for any such
                  planned change and the equitable cost reallocation or
                  absorption methodology, if any, to be used among the
                  company-clients.

         (3)      To ensure that the Principles expressed in this document are
                  communicated and embraced by all who are critical for the
                  successful continuation of a positive and productive
                  partnership, the management representatives whose signatures
                  appear below, confirm their commitment to fulfilling the
                  expectations and undertakings described herein and in the
                  attached Appendices.

SERVICE METRICS

KEY PERFORMANCE MEASURES
There are three types of measures: Cost (C), Quality (Q) or Time (T).

Cost Measures:

1. Achieve annual budget projection for CPA.
         Threshold goal - meet budget projection
         Target goal - under budget by 2% on non-labor costs
         Stretch goal - under budget by 4% on non-labor costs

         Unusual variations in work requests, frequency, etc. will be
communicated to CPA as promptly as possible and SLS and the CPA General Counsel
will discuss and modify expectations, as appropriate.

2. On an as-requested basis (but no more frequently than annually) provide a
comparison of SLS labor costs to market rates for substantially similar legal
services.

         Acceptable - if at or below the cost of an alternative provider
         Excellent - if less than 90% of the alternative provider's costs
         Unacceptable - if exceed alternative provider's costs


Quality and Timeliness Measures:

Prepare and provide CPA an annual customer survey that will measure (1)
timeliness of response, (2) work quality, and (3) communications and achieve
satisfactory service ratings in all three measured categories. Satisfactory
service ratings are defined as SLS having met or exceeded the customers'
expectations as outlined below:

PERFORMANCE MEASURES

This section describes the key measures for each service that Engineering
Services and CGV concur will be used as the basis to monitor, evaluate and
continuously improve the performance of the services provided. The types of
measures are Cost (C) or Quality (Q).

OTHER MATTERS

Engineering Services and CGV also intend that prior to the start of the
provision of any service as contemplated in this service level plan, the key
contacts will define expectations that may include any of the following
elements: timeline, cost limitations, customer responsibilities, timing of
status reports, customer needs, regulatory approval, favorable internal audits
or accuracy of lab results.

If necessary, Engineering Services is authorized to sign non-disclosure
agreements with external providers, such as manufacturers, on CGV's behalf.


LABOR UTILIZATION/AMENDMENTS

Successful implementation of the SLP assumes reasonably consistent utilization
of assigned FTE's during each quarter of 1999.

Should service levels exceed assigned FTE levels, every effort will be made to
meet those requirements within the current cost structure. In the event that
additional services indicate that the SLP budget will be exceeded, Engineering
Services will notify CGV for verification and approval.

Should assigned FTE levels not be utilized fully, every effort will be make the
services available to other parties and/or redirect unused FTE's to other Shared
Services units provided that the FTE skill sets are transferable; however, CGV
will be responsible for any stranded cost associated with unused or
underutilized FTE complement.

If modifications to this plan are required, Engineering Services will contact
CGV to reprioritize requested services or renegotiate costs. Amendments to this
plan will be issued upon renegotiation.

If any unforeseen circumstances require CGV to implement significant
cost-cutting measures, Engineering Services will make every attempt to implement
similar measures.

KEY PERFORMANCE MEASURES

This section describes the key measures for each service that Engineering
Services and CKY concur will be used as the basis to monitor, evaluate and
continuously improve the performance of the services provided. The types of
measures are Cost (C) or Quality (Q).

OTHER MATTERS

Engineering Services and CKY also intend that prior to the start of the
provision of any service as contemplated in this service level plan, the key
contacts will define expectations that may include any of the following
elements: timeline, cost limitations, customer responsibilities, timing of
status reports, customer needs, regulatory approval, favorable internal audits
or accuracy of lab results.

If necessary, Engineering Services is authorized to sign non-disclosure
agreements with external providers, such as manufacturers, on CKY's behalf.


LABOR UTILIZATION/AMENDMENTS

Successful implementation of the SLP assumes reasonably consistent utilization
of assigned FTE's during each quarter of 1999.

Should service levels exceed assigned FTE levels, every effort will be made to
meet those requirements within the current cost structure. In the event that
additional services indicate that the SLP budget will be exceeded, Engineering
Services will notify CKY for verification and approval.

Should assigned FTE levels not be utilized fully, every effort will be make the
services available to other parties and/or redirect unused FTE's to other Shared
Services units provided that the FTE skill sets are transferable; however, CKY
will be responsible for any stranded cost associated with unused or
underutilized FTE complement.

If modifications to this plan are required, Engineering Services will contact
CKY to reprioritize requested services or renegotiate costs. Amendments to this
plan will be issued upon renegotiation.

If any unforeseen circumstances require CKY to implement significant
cost-cutting measures, Engineering Services will make every attempt to implement
similar measures.

OTHER MATTERS

Engineering Services and CMD also intend that prior to the start of the
provision of any service as contemplated in this service level plan, the key
contacts will define expectations that may include any of the following
elements: timeline, cost limitations, customer responsibilities, timing of
status reports, customer needs, regulatory approval, favorable internal audits
or accuracy of lab results.

If necessary, Engineering Services is authorized to sign non-disclosure
agreements with external providers, such as manufacturers, on CMD's behalf.


LABOR UTILIZATION/AMENDMENTS

Successful implementation of the SLP assumes reasonably consistent utilization
of assigned FTE's during each quarter of 1999.

Should service levels exceed assigned FTE levels, every effort will be made to
meet those requirements within the current cost structure. In the event that
additional services indicate that the SLP budget will be exceeded, Engineering
Services will notify CMD for verification and approval.

Should assigned FTE levels not be utilized fully, every effort will be make the
services available to other parties and/or redirect unused FTE's to other Shared
Services units provided that the FTE skill sets are transferable; however, CMD
will be responsible for any stranded cost associated with unused or
underutilized FTE complement.

If modifications to this plan are required, Engineering Services will contact
CMD to reprioritize requested services or renegotiate costs. Amendments to this
plan will be issued upon renegotiation.

If any unforeseen circumstances require CMD to implement significant
cost-cutting measures, Engineering Services will make every attempt to implement
similar measures.

OTHER MATTERS

Engineering Services and COH also intend that prior to the start of the
provision of any service as contemplated in this service level plan, the key
contacts will define expectations that may include any of the following
elements: timeline, cost limitations, customer responsibilities, timing of
status reports, customer needs, regulatory approval, favorable internal audits
or accuracy of lab results.

If necessary, Engineering Services is authorized to sign non-disclosure
agreements with external providers, such as manufacturers, on COH's behalf.


LABOR UTILIZATION/AMENDMENTS

Successful implementation of the SLP assumes reasonably consistent utilization
of assigned FTE's during each quarter of 1999.

Should service levels exceed assigned FTE levels, every effort will be made to
meet those requirements within the current cost structure. In the event that
additional services indicate that the SLP budget will be exceeded, Engineering
Services will notify COH for verification and approval.

Should assigned FTE levels not be utilized fully, every effort will be make the
services available to other parties and/or redirect unused FTE's to other Shared
Services units provided that the FTE skill sets are transferable; however, COH
will be responsible for any stranded cost associated with unused or
underutilized FTE complement.

If modifications to this plan are required, Engineering Services will contact
COH to reprioritize requested services or renegotiate costs. Amendments to this
plan will be issued upon renegotiation.

If any unforeseen circumstances require COH to implement significant
cost-cutting measures, Engineering Services will make every attempt to implement
similar measures.

OTHER MATTERS

Engineering Services and CPA also intend that prior to the start of the
provision of any service as contemplated in this service level plan, the key
contacts will define expectations that may include any of the following
elements: timeline, cost limitations, customer responsibilities, timing of
status reports, customer needs, regulatory approval, favorable internal audits
or accuracy of lab results.

If necessary, Engineering Services is authorized to sign non-disclosure
agreements with external providers, such as manufacturers, on CPA's behalf.


LABOR UTILIZATION/AMENDMENTS

Successful implementation of the SLP assumes reasonably consistent utilization
of assigned FTE's during each quarter of 1999.

Should service levels exceed assigned FTE levels, every effort will be made to
meet those requirements within the current cost structure. In the event that
additional services indicate that the SLP budget will be exceeded, Engineering
Services will notify CPA for verification and approval.

Should assigned FTE levels not be utilized fully, every effort will be make the
services available to other parties and/or redirect unused FTE's to other Shared
Services units provided that the FTE skill sets are transferable; however, CPA
will be responsible for any stranded cost associated with unused or
underutilized FTE complement.

If modifications to this plan are required, Engineering Services will contact
CPA to reprioritize requested services or renegotiate costs. Amendments to this
plan will be issued upon renegotiation.

If any unforeseen circumstances require CPA to implement significant
cost-cutting measures, Engineering Services will make every attempt to implement
similar measures.

                                          for Sales Support Services provided to
                                                  Columbia Gas of Virginia, Inc.

OVERVIEW

The keystone of effective shared service arrangements is a strong
customer-service orientation. The shared services approach incorporates
mechanisms for:

- -        Enhanced understanding and effective management of costs;

- -        Continuously improving service quality;

- -        Encouraging personal accountability.

If these objectives are to be met, it is essential to develop enhanced methods
of communicating between the operating companies and service providers.

This Service Level Plan (SLP) is a primary means of communication, incorporating
the mutual expectations of the Sales Support Service Section and Columbia Gas of
Virginia, Inc. regarding specific types of services expected to be used, the
primary users, projected allocations, evaluation criteria and the projected cost
of each of those services. A strong provider-customer relationship built upon
the discussions and understandings reflected in this Plan will better enable the
distribution companies to have access to highly valued services at low cost.

Through the Shared Services Center (SSC), services will be provided that are:

- -        Requested or agreed to by the operating company customer;

- -        Evaluated on an ongoing basis according to the agreed-upon performance
         measures;

- -        Priced at cost, as required by the Public Utility Holding Company Act
         of 1935, as amended.

the Sales Support services detailed in the table below. "Direct" costs are those
costs Sales Support will incur explicitly to provide the specific service, such
as hourly labor rates, computer-related charges and out-of-the pocket expenses.
"Overhead" costs represent the proportionate share of the costs incurred to
support all of the services, such as building costs, labor benefits, and the
expenses of administering the SSC. Overhead costs are not specifically
identified on the Customer's books as associated with individual services. The
"total cost of service" is the sum of the Direct and Overhead costs. It is the
Total amount Sales Support will monitor through the Service Performance Reports.

                                                   Columbia Gas of Kentucky, Inc

OVERVIEW

The keystone of effective shared service arrangements is a strong
customer-service orientation. The shared services approach incorporates
mechanisms for:

- -        Enhanced understanding and effective management of costs;
- -        Continuously improving service quality;
- -        Encouraging personal accountability.

If these objectives are to be met, it is essential to develop enhanced methods
of communicating between the operating companies and service providers.

This Service Level Plan (SLP) is a primary means of communication, incorporating
the mutual expectations of the Sales Support Service Section and Columbia Gas of
Kentucky, Inc. regarding specific types of services expected to be used, the
primary users, projected allocations, evaluation criteria and the projected cost
of each of those services. A strong provider-customer relationship built upon
the discussions and understandings reflected in this Plan will better enable the
distribution companies to have access to highly valued services at low cost.

Through the Shared Services Center (SSC), services will be provided that are:

- -        Requested or agreed to by the operating company customer;
- -        Evaluated on an ongoing basis according to the agreed-upon performance
         measures;
- -        Priced at cost, as required by the Public Utility Holding Company Act
         of 1935, as amended.

PROJECTED SERVICE LEVELS AND COSTS

This table is a summary of the projected allocations and annual cost to provide
the Sales Support services detailed in the table below. "Direct" costs are those
costs Sales Support will incur explicitly to provide the specific service, such
as hourly labor rates, computer-related charges and out-of-the pocket expenses.
"Overhead" costs represent the proportionate share of the costs incurred to
support all of the services, such as building costs, labor benefits, and the
expenses of administering the SSC. Overhead costs are not specifically
identified on the Customer's books as associated with individual services. The
"total cost of service" is the sum of the Direct and Overhead costs. It is the
Total amount Sales Support will monitor through the Service Performance Reports.

OVERVIEW

The keystone of effective shared service arrangements is a strong
customer-service orientation. The shared services approach incorporates
mechanisms for:

- -        Enhanced understanding and effective management of costs;
- -        Continuously improving service quality;
- -        Encouraging personal accountability.

If these objectives are to be met, it is essential to develop enhanced methods
of communicating between the operating companies and service providers.

This Service Level Plan (SLP) is a primary means of communication, incorporating
the mutual expectations of the Sales Support Service Section and Columbia Gas of
Maryland, Inc. regarding specific types of services expected to be used, the
primary users, projected allocations, evaluation criteria and the projected cost
of each of those services. A strong provider-customer relationship built upon
the discussions and understandings reflected in this Plan will better enable the
distribution companies to have access to highly valued services at low cost.

Through the Shared Services Center (SSC), services will be provided that are:

- -        Requested or agreed to by the operating company customer;
- -        Evaluated on an ongoing basis according to the agreed-upon performance
         measures;
- -        Priced at cost, as required by the Public Utility Holding Company Act
         of 1935, as amended.

OTHER MATTERS

Sales Support and Customer also intend that prior to the start of the provision
of any service as contemplated in the Service Level Plan, the Primary Sales
Support contact and the Primary Customer contact will define expectations that
could include any of the following elements:

- -        Timeline;
- -        Cost limitations;
- -        Customer responsibilities;
- -        Timing and status reports;
- -        Customer needs;
- -        Regulatory approval;
- -        Favorable internal audits.

MODIFICATIONS TO THE PLAN

This Service Level Plan anticipates a service level allocation. The Sales
Support Section will monitor customer usage and, if usage is projected to exceed
stated level, Sales Support will contact the Customer to reprioritize the
provision of requested service or renegotiate costs to provide incremental
service requirements. Amendments to the Plan will be issued if a renegotiation
occurs.

The costs reflected herein are based on information available as of April 24,
2000.

OTHER MATTERS

Sales Support and Customer also intend that prior to the start of the provision
of any service as contemplated in the Service Level Plan, the Primary Sales
Support contact and the Primary Customer contact will define expectations that
could include any of the following elements:

- -        Timeline;
- -        Cost limitations;
- -        Customer responsibilities;
- -        Timing and status reports;
- -        Customer needs;
- -        Regulatory approval;
- -        Favorable internal audits.

MODIFICATIONS TO THE PLAN

This Service Level Plan anticipates a service level allocation. The Sales
Support Section will monitor customer usage and, if usage is projected to exceed
stated level, Sales Support will contact the Customer to reprioritize the
provision of requested service or renegotiate costs to provide incremental
service requirements. Amendments to the Plan will be issued if a renegotiation
occurs.

The costs reflected herein are based on information available as of April 24,
2000.

                                          for Sales Support Services provided to
                                                      Columbia Gas of Ohio, Inc.

OVERVIEW

The keystone of effective shared service arrangements is a strong
customer-service orientation. The shared services approach incorporates
mechanisms for:

- -        Enhanced understanding and effective management of costs;
- -        Continuously improving service quality;
- -        Encouraging personal accountability.

If these objectives are to be met, it is essential to develop enhanced methods
of communicating between the operating companies and service providers.

This Service Level Plan (SLP) is a primary means of communication, incorporating
the mutual expectations of the Sales Support Service Section and Columbia Gas of
Ohio, Inc. regarding specific types of services expected to be used, the primary
users, projected allocations, evaluation criteria and the projected cost of each
of those services. A strong provider-customer relationship built upon the
discussions and understandings reflected in this Plan will better enable the
distribution companies to have access to highly valued services at low cost.

Through the Shared Services Center (SSC), services will be provided that are:

- -        Requested or agreed to by the operating company customer;
- -        Evaluated on an ongoing basis according to the agreed-upon performance
         measures;
- -        Priced at cost, as required by the Public Utility Holding Company Act
         of 1935, as amended.

MULTI-YEAR AGREEMENT

Respecting the new competitive environment in which the State Organizations must
operate and the commitment, both internal and external, to stay out of the rate
making process the Sales Support Services Section is offering a flat multi-year
agreement. This SLP will form the basis of communication in calendar years 1998,
1999 and 2000. During this period the Projected Service Levels and Costs shown
on page four will remain constant unless the State Organization initiates
discussions to increase service levels during this period. A multi-year
agreement offers the following benefits:

- -        Supports the President's December 5, 1997 stated strategic vision to
         support the Commercial, Industrial and Large volume markets as we move
         toward becoming "Pipes and Meters Companies."

<PAGE>   349

- -        Guarantees a fixed Sales Support budget for the period unless
         additional services are negotiated. The Sales Support Services Section
         will absorb increases in costs due to inflationary pressures in both
         the O&M and Labor budgets.

- -        Minimizes lost time for budget and SLP discussions/negotiations.

- -        Creates a partnership environment where:

         -        The State Sales and Marketing Representatives recognize the
                  Sales Support Services Section as a long term resource/tool.

         -        Supports longer term projects from concept through
                  implementation rather than only projects which can be
                  completed in a single calendar year.

PROJECTED SERVICE LEVELS AND COSTS

This table is a summary of the projected allocations and annual cost to provide
the Sales Support services detailed in the table on page 3. "Allocation"
measures the level of service to be provided. "Direct" costs are those costs
Sales Support will incur explicitly to provide the specific service, such as
hourly labor rates, computer-related charges and out-of-the pocket expenses.
"Overhead" costs represent the proportionate share of the costs incurred to
support all of the services, such as building costs, labor benefits, and the
expenses of administering the SSC. Overhead costs are not specifically
identified on the Customer's books as associated with individual services. The
"total cost of service" is the sum of the Direct and Overhead costs. It is the
Total amount Sales Support will monitor through the Service Performance Reports.

OTHER MATTERS

Sales Support and Customer also intend that prior to the start of the provision
of any service as contemplated in the Service Level Plan, the Primary Sales
Support contact and the Primary Customer contact will define expectations that
could include any of the following elements:

- -        Timeline;                          -        Customer needs;
- -        Cost limitations;                  -        Regulatory approval;
- -        Customer responsibilities;         -        Favorable internal audits.
- -        Timing and status reports;

MODIFICATIONS TO THE PLAN

It is possible to modify the Plan under the PROCESS FOR SIGNIFICANT CHANGES TO
SERVICE LEVEL PLANS and PRINCIPLES AND RULES TO LIVE BY WHEN CONSIDERING
SIGNIFICANT CHANGES TO SERVICE LEVEL PLAN endorsed by Share Service Board (LDC
Presidents), December 5, 1997. Both documents are incorporated into this Plan by
this reference (See appendix A). Possible reasons for Plan modifications
include:

- -        Significant Strategic change in the State's Sales and Marketing
         direction
- -        Regulatory initiatives.
- -        Other conditions mutually agreed to by both parties.

Additionally this Service Level Plan anticipates a service level allocation. The
Sales Support Section will monitor customer usage and, if usage is projected to
exceed stated level, Sales Support will contact the Customer to reprioritize the
provision of requested service or renegotiate costs to provide incremental
service requirements. Amendments to the Plan will be issued if a renegotiation
occurs.

The costs reflected herein are based on information available as of April 24,
2000 and are subject to change as revised budgets are approved.

OVERVIEW

This Service Level Plan is a primary means of communication, incorporating the
mutual expectations of the Human Resource Consulting Service Section and
Columbia Gas of Virginia regarding specific types of services expected to be
used, the primary users, projected volumes, evaluation criteria and the
projected cost of each of those services for calendar year 1999. A strong
provider-customer relationship built upon the discussions and understandings
reflected in this Plan will better enable the distribution companies to have
access to highly valued services at low cost.

Through the SSC, services will be provided that are: (1) requested or agreed to
by the operating company customer; (2) evaluated on an ongoing basis according
to the agreed-upon performance measures; and (3) priced at cost, as required by
the Public Utility Holding Company Act of 1935, as amended.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected annual cost for each service the Customer
expects to use. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific service, such as hourly labor rates,
computer-related charges and out-of-pocket expenses. "Overhead" costs represent
the proportionate share of the costs that are incurred to support all services,
such as building costs, labor benefits, and the expenses of administering the
Shared Services Center. Overhead costs are not specifically identified on the
Customer's books as associated with individual services. The "total cost of
service" is the sum of the Direct and the Overhead costs. It is the Total amount
that Provider will monitor through the Service Performance Reports.

OTHER MATTERS

The Provider and Customer acknowledge the following role relationships:

Customers - Human Resource professionals serving as the primary business
partners to the management and staff of their respective organizations. The
owners and drivers of all human resource strategies, policies, and practices in
their organization.

Providers - a primary consulting partner to Customers. Deliver leading-edge
Human Resource Management expertise and skilled consulting support to operating
company Human Resource professionals in achieving their objectives.

The Provider and Customer also intend that prior to the start of the provision
of any major project as described in this service level plan, the Primary
Provider and Primary Customer will define expectations that could include any of
the following elements: project definition, objectives/goals, deliverables,
people to be involved, role definitions, time schedules, progress review/report
frequency, and cost, time and support requirements/limitations.

While the Internal Customer Survey will be a key Source of Information to
formally monitor and measure the Provider's progress in achieving Key
Performance Measures, the means by which such surveying will be carried out
(e.g., electronic, printed, telephone, face-to-face) will be determined
according to the expressed preference of the Customer.

volume and costs will be directed to support the efforts of the Shared Service
Center organization, which in turn is providing direct support to other areas of
the Customer's state organization.


MODIFICATIONS TO THE PLAN

Service Provider and Customer will monitor service usage. If substantially
exceeding budget, Provider will contact Customer to mutually reprioritize
provision of requested service or renegotiate costs to provide incremental
service requirements. Amendments to this plan will be issued if a renegotiation
occurs.

The costs reflected herein are based on information available as of December 8,
1997, and are subject to change as revised budgets are approved.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected annual cost for each service the Customer
expects to use. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific service, such as hourly labor rates,
computer-related charges and out-of-pocket expenses. "Overhead" costs represent
the proportionate share of the costs that are incurred to support all services,
such as building costs, labor benefits, and the expenses of administering the
Shared Services Center. Overhead costs are not specifically identified on the
Customer's books as associated with individual services. The "total cost of
service" is the sum of the Direct and the Overhead costs. It is the Total amount
that Provider will monitor through the Service Performance Reports.

                                                      Columbia Gas of Ohio, Inc.




OVERVIEW

This Service Level Plan is a primary means of communication, incorporating the
mutual expectations of the Human Resource Consulting Service Section and
Columbia Gas of Ohio, Inc. regarding specific types of services expected to be
used, the primary users, projected volumes, evaluation criteria and the
projected cost of each of those services for calendar year 1999. A strong
provider-customer relationship built upon the discussions and understandings
reflected in this Plan will better enable the distribution companies to have
access to highly valued services at low cost.

Through the SSC, services will be provided that are: (1) requested or agreed to
by the operating company customer; (2) evaluated on an ongoing basis according
to the agreed-upon performance measures; and (3) priced at cost, as required by
the Public Utility Holding Company Act of 1935, as amended.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected annual cost for each service the Customer
expects to use. "Direct" costs are those costs the Provider will incur
explicitly to provide the specific service, such as hourly labor rates,
computer-related charges and out-of-pocket expenses. "Overhead" costs represent
the proportionate share of the costs that are incurred to support all services,
such as building costs, labor benefits, and the expenses of administering the
Shared Services Center. Overhead costs are not specifically identified on the
Customer's books as associated with individual services. The "total cost of
service" is the sum of the Direct and the Overhead costs. It is the Total amount
that Provider will monitor through the Service Performance Reports.

OTHER MATTERS

The Provider and Customer acknowledge the following role relationships:

Customers - Human Resource professionals serving as the primary business
partners to the management and staff of their respective organizations. The
owners and drivers of all human resource strategies, policies, and practices in
their organization.

Providers - a primary consulting partner to Customers. Deliver leading-edge
Human Resource Management expertise and skilled consulting support to operating
company Human Resource professionals in achieving their objectives.

The Provider and Customer also intend that prior to the start of the provision
of any major project as described in this service level plan, the Primary
Provider and Primary Customer will define expectations that could include any of
the following elements: project definition, objectives/goals, deliverables,
people to be involved, role definitions, time schedules, progress review/report
frequency, and cost, time and support requirements/limitations.

While the Internal Customer Survey will be a key Source of Information to
formally monitor and measure the Provider's progress in achieving Key
Performance Measures, the means by which such surveying will be carried out
(e.g., electronic, printed, telephone, face-to-face) will be determined
according to the expressed preference of the Customer.

The Provider and Customer understand that a portion of the projected service
volume and costs will be directed to support the efforts of the Shared Service
Center organization, which in turn is providing direct support to other areas of
the Customer's state organization.


MODIFICATIONS TO THE PLAN

Service Provider and Customer will monitor service usage. If substantially
exceeding budget, Provider will contact Customer to mutually reprioritize
provision of requested service or renegotiate costs to provide incremental
service requirements. Amendments to this plan will be issued if a renegotiation
occurs.

The costs reflected herein are based on information available as of December 8,
1997, and are subject to change as revised budgets are approved.

OTHER MATTERS

The Provider and Customer acknowledge the following role relationships:

Customers - Human Resource professionals serving as the primary business
partners to the management and staff of their respective organizations. The
owners and drivers of all human resource strategies, policies, and practices in
their organization.

Providers - a primary consulting partner to Customers. Deliver leading-edge
Human Resource Management expertise and skilled consulting support to operating
company Human Resource professionals in achieving their objectives.

The Provider and Customer also intend that prior to the start of the provision
of any major project as described in this service level plan, the Primary
Provider and Primary Customer will define expectations that could include any of
the following elements: project definition, objectives/goals, deliverables,
people to be involved, role definitions, time schedules, progress review/report
frequency, and cost, time and support requirements/limitations.

While the Internal Customer Survey will be a key Source of Information to
formally monitor and measure the Provider's progress in achieving Key
Performance Measures, the means by which such surveying will be carried out
(e.g., electronic, printed, telephone, face-to-face) will be determined
according to the expressed preference of the Customer.

The Provider and Customer understand that a portion of the projected service
volume and costs will be directed to support the efforts of the Shared Service
Center organization, which in turn is providing direct support to other areas of
the Customer's state organization.


MODIFICATIONS TO THE PLAN

Service Provider and Customer will monitor service usage. If substantially
exceeding budget, Provider will contact Customer to mutually reprioritize
provision of requested service or renegotiate costs to provide incremental
service requirements. Amendments to this plan will be issued if a renegotiation
occurs.

The costs reflected herein are based on information available as of December 8,
1997, and are subject to change as revised budgets are approved.

PROJECTED SERVICE LEVELS AND COSTS


This table summarizes the projected volume and the annual cost of each service
the Customer expects to use. "Volume" measures the expected employee complement
required to provide each service. "Direct" costs are those costs the Provider
will incur explicitly to provide the specific service, such as hourly labor
rates, computer-related charges and out-of-pocket expenses. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as building costs, labor benefits, and the expenses of
administering the Shared Services Center. Overhead costs are not specifically
identified on the Customer's books as associated with individual services. The
"total cost of service" is the sum of the Direct and the Overhead costs. It is
the Total amount that Provider will monitor through the Service Performance
Reports.

OTHER MATTERS

The Provider and Customer also intend that:

Contract Signature Authority

The Vice President of Columbia Gas of Kentucky, Inc., (Joseph W. Kelly) and
General Manager of Gas Management Services (Jim Lee) will execute all contracts
for capacity and supply with a term longer than one year and the General Manager
of Gas Management Services (GMS) will execute all contracts with a term of one
year or less.

Decision Guidelines

A Decision Guideline is necessary in recognition of the operational and revenue
impact that the GMS organization can have on CKY.

The 1999 SLP Decision Guidelines are attached as Exhibit I. The desired outcome
is that by following the guidelines, 90 plus percent of the operational
decisions can be made by GMS without specific approval of the Customer, and that
the Customer has direct input and decision making capabilities on the issues of
the greatest importance to the Customer.

GMS Incentive Pay Plan

A GMS Incentive Plan shall be proposed and incorporated for 1999.

The Gas Management Services (GMS) Incentive Plan is an employee award program
developed to increase Columbia LDC revenues by:

1)   Directly rewarding the employees in GMS for generating revenue, and

2)   Focusing and aligning all GMS employees as a team on non-traditional
     revenue generating actions and the innovative creation of new
     opportunities.


MODIFICATIONS TO THE PLAN

Both the Provider and the Customer anticipate that the Customer will require the
services provided under this Service Level Plan for an indefinite period of
time. To minimize the administrative burden and delays associated with the
redefinition of services and performance metrics on an annual basis, the 1999
Plan will automatically continue from year to year until either the Provider or
the Customer requests that the Plan be substantially revised. Both Provider and
Customer expressly exclude from the scope of this automatic renewal provision
the Projected Service Levels and Costs, found on page 3 of this Plan, which
shall be the only portion of the Plan that would need to be examined and
established annually.

Provider and Customer intend to address any interim changes to the Plan through
on-going discussions and to reach agreement as business necessity dictates.

will be provided that are: (1) requested or agreed to by the operating company
customer; (2) evaluated on an ongoing basis according to the agreed-upon

PROJECTED SERVICE LEVELS AND COSTS


This table summarizes the projected volume and the annual cost of each service
the Customer expects to use. "Volume" measures the expected employee complement
required to provide each service. "Direct" costs are those costs the Provider
will incur explicitly to provide the specific service, such as hourly labor
rates, computer-related charges and out-of-pocket expenses. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as building costs, labor benefits, and the expenses of
administering the Shared Services Center. Overhead costs are not specifically
identified on the Customer's books as associated with individual services. The
"total cost of service" is the sum of the Direct and the Overhead costs. It is
the Total amount that Provider will monitor through the Service Performance
Reports.

OTHER MATTERS

The Provider and Customer also intend that:

Contract Signature Authority

The President of Columbia Gas of Maryland, Inc., (G. J.Robinson) will execute
all contracts for capacity and supply with a term longer than one year and the
General Manager of Gas Management Services (GMS) will execute all contracts with
a term of one year or less.

Decision Guidelines

A Decision Guideline is necessary in recognition of the operational and revenue
impact that the GMS organization can have on CMD.

The 1999 SLP Decision Guidelines are attached as Exhibit I. The desired outcome
is that by following the guidelines, 90 plus percent of the operational
decisions can be made by GMS without specific approval of the Customer, and that
the Customer has direct input and decision making capabilities on the issues of
the greatest importance to the Customer.

GMS Incentive Pay Plan

A GMS Incentive Plan shall be proposed and incorporated for 1999.

The Gas Management Services (GMS) Incentive Plan is an employee award program
developed to increase Columbia LDC revenues by:

1)   Directly rewarding the employees in GMS for generating revenue, and


2)   Focusing and aligning all GMS employees as a team on non-traditional
     revenue generating actions and the innovative creation of new
     opportunities.


MODIFICATIONS TO THE PLAN

Both the Provider and the Customer anticipate that the Customer will require the
services provided under this Service Level Plan for an indefinite period of time
into the future.

Provider and Customer intend to address any interim changes to the Plan through
on-going discussions and to reach agreement as business necessity dictates.

PROJECTED SERVICE LEVELS AND COSTS


This table summarizes the projected volume and the annual cost of each service
the Customer expects to use. "Volume" measures the expected employee complement
required to provide each service. "Direct" costs are those costs the Provider
will incur explicitly to provide the specific service, such as hourly labor
rates, computer-related charges and out-of-pocket expenses. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as building costs, labor benefits, and the expenses of
administering the Shared Services Center. Overhead costs are not specifically
identified on the Customer's books as associated with individual services. The
"total cost of service" is the sum of the Direct and the Overhead costs. It is
the Total amount that Provider will monitor through the Service Performance
Reports.

OTHER MATTERS

The Provider and Customer also intend that:

Contract Signature Authority

The Senior Vice President of Energy Services and General Manager of Gas
Management Services (Jim Lee) will execute all contracts for capacity and
supply.

Decision Guidelines

A Decision Guideline is necessary in recognition of the operational and revenue
impact that the GMS organization can have on COH.

The 1999 SLP Decision Guidelines are attached as Exhibit I. The desired outcome
is that by following the guidelines, 90 plus percent of the operational
decisions can be made by GMS without specific approval of the Customer, and that
the Customer has direct input and decision making capabilities on the issues of
the greatest importance to the Customer.

GMS Incentive Pay Plan

A GMS Incentive Plan shall be proposed and incorporated for 1999.

The Gas Management Services (GMS) Incentive Plan is an employee award program
developed to increase Columbia LDC revenues by:

1)   Directly rewarding the employees in GMS for generating revenue, and

2)   Focusing and aligning all GMS employees as a team on non-traditional
     revenue generating actions and the innovative creation of new
     opportunities.

MODIFICATIONS TO THE PLAN

Both the Provider and the Customer anticipate that the Customer will require the
services provided under this Service Level Plan for an indefinite period of
time. To minimize the administrative burden and delays associated with the
redefinition of services and performance metrics on an annual basis, the 1999
Plan will automatically continue from year to year until either the Provider or
the Customer requests that the Plan be substantially revised. Both Provider and
Customer expressly exclude from the scope of this automatic renewal provision
the Projected Service Levels and Costs, found on page 3 of this Plan, which
shall be the only portion of the Plan that would need to be examined and
established annually.

Provider and Customer intend to address any interim changes to the Plan through
on-going discussions and to reach agreement as business necessity dictates.

MANAGEMENT COMMITMENT

In the spirit of business partnership, the Management representatives signing
below confirm their commitment to fulfill the expectations and undertakings
described within this Plan.

PROJECTED SERVICE LEVELS AND COSTS


This table summarizes the projected volume and the annual cost of each service
the Customer expects to use. "Volume" measures the expected employee complement
required to provide each service. "Direct" costs are those costs the Provider
will incur explicitly to provide the specific service, such as hourly labor
rates, computer-related charges and out-of-pocket expenses. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as building costs, labor benefits, and the expenses of
administering the Shared Services Center. Overhead costs are not specifically
identified on the Customer's books as associated with individual services. The
"total cost of service" is the sum of the Direct and the Overhead costs. It is
the Total amount that Provider will monitor through the Service Performance
Reports.

OTHER MATTERS

The Provider and Customer also intend that:

Contract Signature Authority

The President of Columbia Gas of Pennsylvania, Inc., (G. J. Robinson) will
execute all contracts for capacity and supply with a term longer than one year
and the General Manager of Gas Management Services (GMS) will execute all
contracts with a term of one year or less.

Decision Guidelines

A Decision Guideline is necessary in recognition of the operational and revenue
impact that the GMS organization can have on CPA.

The 1999 SLP Decision Guidelines are attached as Exhibit I. The desired outcome
is that by following the guidelines, 90 plus percent of the operational
decisions can be made by GMS without specific approval of the Customer, and that
the Customer has direct input and decision making capabilities on the issues of
the greatest importance to the Customer.

GMS Incentive Pay Plan

A GMS Incentive Plan shall be proposed and incorporated for 1999.

The Gas Management Services (GMS) Incentive Plan is an employee award program
developed to increase Columbia LDC revenues by:

1)       Directly rewarding the employees in GMS for generating revenue, and

2)       Focusing and aligning all GMS employees as a team on non-traditional
         revenue generating actions and the innovative creation of new
         opportunities.


MODIFICATIONS TO THE PLAN

Both the Provider and the Customer anticipate that the Customer will require the
services provided under this Service Level Plan for an indefinite period of time
into the future.

Provider and Customer intend to address any interim changes to the Plan through
on-going discussions and to reach agreement as business necessity dictates.

PROJECTED SERVICE LEVELS AND COSTS

This table summarizes the projected volume and the annual cost of each service
the Customer expects to use. "Volume" measures the expected employee complement
required to provide each service. "Direct" costs are those costs the Provider
will incur explicitly to provide the specific service, such as hourly labor
rates, computer-related charges and out-of-pocket expenses. "Overhead" costs
represent the proportionate share of the costs that are incurred to support all
services, such as building costs, labor benefits, and the expenses of
administering the Shared Services Center. Overhead costs are not specifically
identified on the Customer's books as associated with individual services. The
"total cost of service" is the sum of the Direct and the Overhead costs. It is
the Total amount that Provider will monitor through the Service Performance
Reports.

OTHER MATTERS

The Provider and Customer also intend that:

Contract Signature Authority
The President of Columbia Gas of Virginia, Inc., (Anthony Trubisz) will execute
all contracts for capacity and supply with a term longer than one year and the
General Manager of Gas Management Services (GMS) will execute all contracts with
a term of one year or less.

Decision Guidelines
A Decision Guideline is necessary in recognition of the operational and revenue
impact that the GMS organization can have on CVA.

The 1999 SLP Decision Guidelines are attached as Exhibit I. The desired outcome
is that by following the guidelines, 90 plus percent of the operational
decisions can be made by GMS without specific approval of the Customer, and that
the Customer has direct input and decision making capabilities on the issues of
the greatest importance to the Customer.

GMS Incentive Pay Plan

A GMS Incentive Plan shall be proposed and incorporated for 1999.

The Gas Management Services (GMS) Incentive Plan is an employee award program
developed to increase Columbia LDC revenues by:

1)       Directly rewarding the employees in GMS for generating revenue, and
2)       Focusing and aligning all GMS employees as a team on non-traditional
         revenue generating actions and the innovative creation of new
         opportunities.

MODIFICATIONS TO THE PLAN

Both the Provider and the Customer anticipate that the Customer will require the
services provided under this Service Level Plan for an indefinite period of
time. To minimize the administrative burden and delays associated with the
redefinition of services and performance metrics on an annual basis, the 1999
Plan will automatically continue from year to year until either the Provider or
the Customer requests that the Plan be substantially revised. Both Provider and
Customer expressly exclude from the scope of this automatic renewal provision
the Projected Service Levels and Costs, found on page 3 of this Plan, which
shall be the only portion of the Plan that would need to be examined and
established annually.

Provider and Customer intend to address any interim changes to the Plan through
on-going discussions and to reach agreement as business necessity dictates.

                            "AT COST" REPRESENTATION

In compliance with rules 90 and 91 under the Public Utility Holding Company Act,
all services are provided at cost which includes reasonable compensation for
necessary capital.

The basis for determining the amount billed when the Shared Services Center
(SSC) of Columbia Gas of Ohio, Inc. (COH) does work for another affiliate is
cost pursuant to Section 13(b) of the Public Utility Holding Company Act. The
SSC does not make a profit when performing professional services for affiliated
companies.

In addition to costs uniquely identified in each transaction, an attempt is made
to include costs that are related to, but not specifically identifiable to, the
transaction such as various departmental overheads that include
vacation/non-productive time, employee benefits and payroll taxes.

A component to recover the cost of capital is included when assets owned by COH
are used to provide services for affiliated companies. The cost of capital
includes a return on investment and taxes. The return rate is the Ohio Public
Utilities Commission approved rate of return.
