            METHODS OF ALLOCATION FOR CNG SERVICES AND DRI SERVICES


CNG Services and DRI Services shall allocate costs independently.  Each Service
Company shall allocate costs among companies receiving service from it under
this and similar service contracts using the following methods:

I.   The costs of rendering service by the Service Company will include all
     costs of doing business including interest on debt but excluding a return
     for the use of equity capital for which no charge will be made to System
     Companies.

II.  A.   The Service Company will maintain a separate record of the expenses of
          each department. The expenses of each department will include:

          1.   those expenses that are directly attributable to such department,
               and

          2.   an appropriate portion of those office and housekeeping expenses
               that are not directly attributable to a department but which are
               necessary to the operation of such department.

     B.   Expenses of the department will include salaries and wages of
          employees, rent and utilities, materials and supplies, depreciation,
          and all other expenses attributable to the department. The expenses of
          a department will not include:

          1.   those incremental out-of-pocket expenses that are incurred for
               the direct benefit and convenience of an individual company or
               group of companies,

          2.   Service Company overhead expenses, including expenses of the
               corporate secretary's department that are attributable to
               maintaining the corporate existence of the Service Company, and
               all other incidental overhead expenses including those auditing
               fees, internal auditing department expenses and accounting
               department expenses attributable to the Service Company.

     C.   The Service Company will establish annual budgets for controlling the
          expenses of each department and for determining estimated costs to be
          included in interim monthly billing.

III. A.   Employees in each department will be divided into two groups:
<PAGE>

          1.   Group A will include those employees rendering service to System
               Companies, and

          2.   Group B will include those office and general service employees,
               such as secretaries, file clerks and administrative assistants,
                                                -----------------------------
               who generally assist employees in Group A or render other
               housekeeping services and who are not engaged directly in
               rendering service to each Company or a group of companies.

     B.   Expenses set forth in Section II. above will be separated to show:

          1.   salaries and wages of Group A employees, and

          2.   all other expenses of the department.

     C.   There will be attributed to each dollar of a Group A employee's salary
          or wage, that percentage of all other expenses of his department (as
          defined in B above), that his salary or wage is to the total Group A
          salaries and wages of that department.

     D.   Group A employees in each department will maintain a record of the
          time they are employed in rendering service to each company or group
          of companies. An hourly rate will be determined by dividing the total
          expense attributable to a Group A employee as determined under
          subsection C above by the productive hours reported by such employee.

IV.  The charge to the Company for a particular service will be determined by
     multiplying the hours reported by Group A employees in rendering such
     service to each Company by the hourly rates applicable to such employees.
     When such employees render service to a group of companies, the charge to
     each Company will be determined by multiplying the hours attributable to
     the Company under the allocation formulas set forth in Section IX of this
     Exhibit by the hourly rates applicable to such employees.

V.   To the extent appropriate and practical, the foregoing computations of
     hourly rates and charges may be determined for groups of employees within
     reasonable salary range limits.

VI.  Those expenses of the Service Company that are not included in the annual
     expense of a department under Section II. above will be charged to System
     Companies receiving service as follows:

     A.   Incremental out-of-pocket costs incurred for the direct benefit and
          convenience of a company or group of companies will be charged
          directly to such company or group of companies.  Such costs incurred
          for a group of companies will be allocated on the basis of an
          appropriate formula.

                                       2
<PAGE>

      B.   Service Company overhead expenses referred to in Section II. above
           will be charged to the Company in the proportion that the charges
           made to the Company for costs, other than those set forth in this
           Section VI., are to the total of such charges to all companies
           receiving service.

VII.  Notwithstanding the foregoing basis of determining cost allocations for
      billing purposes, cost allocations for certain services involving machine
      operations and production units will be determined on an appropriate basis
      established by the Service Company relating to the direct use of machine
      equipment or production units.

VIII. Monthly bills will be issued for the services rendered to the Company on
      an actual or estimated basis. Estimates will normally be predicated on
      service department budgets and estimated productive hours of employees for
      the year. At the end of each year, estimated figures will be revised to
      reflect actual experience during such year and adjustments will be made in
      amounts billed to give effect to such revision.

IX.   When Group A employees render services to a group of companies, the
      following formulas shall be used to allocate the time of such employees to
      the individual companies receiving such service:

      A.  The Service Department or Function formulas to be used when employees
          render services to all companies participating in such service, for
          the services indicated are set forth below. When necessary during the
          period 1999-2002, the allocation formulas described below will be
          calculated (in part or in whole) using data based on services
          performed for System Companies Dominion Resources, Inc., prior to the
          merger of Dominion Resources, Inc. and Consolidated Natural Gas
          Company.
