METHODS OF ALLOCATION FOR DES

DES 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 DES 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 Dominion Companies.

 

II.      A. DES 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 Dominion Company or group of Dominion
Companies,

 

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

 

  C. DES 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:

 

  1. Group A will include those employees rendering service to Dominion
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 Dominion Company or a group of
Dominion 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 such employee’s department (as
defined in B above), that such employee’s 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 Dominion Company or group of
Dominion 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 Dominion Company for a particular service will be
determined by multiplying the hours reported by Group A employees in rendering
such service to each Dominion Company by the hourly rates applicable to such
employees. When such employees render service to a group of Dominion Companies,
the charge to each Dominion Company will be determined by multiplying the hours
attributable to the Dominion 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.

 

2

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

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

 

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

 

  B. DES overhead expenses referred to in Section II above will be charged to
the Dominion Company either on the proportion of direct charges to that Dominion
Company or under the allocation formulas set forth in Section IX of this
Exhibit.

 

VII. Notwithstanding the foregoing basis of determining cost allocations for
billing purposes, cost allocations for certain services involving machine
operations, production or service units, or facilities cost will be determined
on an appropriate basis established by DES.

 

VIII. Monthly bills will be issued for the services rendered to the Dominion
Company on an actual basis. However, if such actual information is not available
at the time of preparation of the monthly bill, estimates may be used. Estimates
will normally be predicated on service department budgets and estimated
productive hours of employees for the year. At the end of each quarter,
estimated figures will be revised 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 Dominion Companies, the
following formulas shall be used to allocate the time of such employees to the
individual Dominion Companies receiving such service (Each Dominion Company
metric/Total Dominion Companies’ metrics):

 

  A. The Service Department or Function formulas to be used when employees
