1. Formation of Interregional Distribution Grid Company JSC IDGC of the Center December 20,2007

2. 1 Strategy of cost evaluation of IDGC/DGC and main proposals

3. 2 Evaluation Strategy

4. 3 Main propositions of DCF evaluation * Plan of organic growth ** On the basis of average historical exceeding of the tariff growth over inflation. *

5. 4 Calculation of tariffs according to the method of the investment capital profitability (RAB) It is supposed that from 2010 to 2012 Expenses+ strategy of tariff regulation on transfer of e/energy through distribution grids will be replaced by the method of profitability of the invested capital ( RAB –return on Regulatory Asset Base). The essence of RAB strategy is guarantee of full return of the means invested into the assets of the company during the fixed period that corresponds to the terms of validity of the assets and reception of the stable income the level of which is defined by the regulator that must conform to the risk profile of DGC and guarantee attractiveness of the branch for the investors. Operational expenses include all the field costs of the company except for amortization of the fixed assets, intangible assets. Return on the capital base must guarantee reproduction of the assets that are effectively used at transfer of electric energy through DGC’s grids. Profit of the capital base is defined by the norm of profitability (regulatory WACC) fixed by the regulator the stake of which will be fixed for the long-term period of regulation equal to all DGC. = + + Necessary gross return by RAB method Operational expenses Return on the capital base Profit of the capital base Capital base x WACC (regulatory)

6. 5 Calculation of the capital base for tariff calculation by RAB method = + + Regulatory capital base (as of the beginning of 2010) Initial capital as of the beginning of 2010 Cost of capital investments for 2H2007-2009. Circulating capital as of the beginning of 2010 For the purpose of correct prognosis of indicators of the operational activity of the distribution grid companies after switch to the system of regulation of their tariffs on the basis of RAB method, calculation of the regulator capital base for the moment of the planned introduction of new rules of tariff design (beginning of 2010) was realised. The initial capital is defined as the cost of the fixed assets that are on the balance of the company as of June 30,2007 and that were re-estimated according to Russian Accounting Standards for the end of 2009. Capital investments for 2H2007-2009 from business plans of the companies Circulating capital is defined on the basis of the existing circulation factors and their correspondence to average branch indicators during the accounting period. In the following years of the regulation period the regulatory capital base is calculated by the following way: = + - Regulatory capital base Regulatory capital base of the previous year Investments on the level of amortization of the previous year Change of the circulating capital + Amortization

7. 6 The initial capital used for defining of the regulatory capital base as of the beginning of 2010 is defined as the full cost of asset replacement with regard of their physical depreciation: The initial capital is defined proceeding from the current legislation concerning estimation of cost of the fixed assets for the purpose of book keeping Only the industrial assets are included into initial base of the invested capital (OL, substations, transformer substations), non-profile assets are not considered at calculation of the capital base The investments that were realised at the expense of payment for technical connection are not included into the capital base in order to avoid double calculation.  Full cost of replacement is defined as cost of production or construction under the current conditions of the similar new object that by its functional characteristics is as much as possible similar to the estimated object. Physical depreciation is price decrease due to depreciation, dilapidation and aging, and also deterioration of properties that cannot be eliminated at the expense of the current service.

9. 8 Macroeconomic assumptions for model building The main cost items are predicted on the basis of price indexes in the industry of the RF. Wage expenses are predicted in accordance with the pay indexes Prognosis of electric energy losses in physical terms is based on linear variation of the given indicator during the horizon period and achievement of the target indicator by 2015 Prognosis of electric energy losses in percent to net supply for 2015 is provided by JSC UES FGC Calculation of flat cost is based on the following assumptions: Macroeconomic assumptions Indicators 6 months of 2007 20082009201020112012201320142015 Inflation in the RF,CPI4,50%8,00%7,60%7,10%6,50%6,00%5,50%4,50%4,00% Cumulative inflation index108,00%116,20%124,50%132,50%140,50%148,20%154,90%161,10%167,50% Price index in the industry of the RF, PPI 4,90%9,00%8,00%7,00%6,50%5,50%5,00%4,00%3,50% Pay index in the RF10,10%13,00%12,00%11,00%13,00%9,00%8,00%7,00% Exchange rate ruble/ US dollar (average annual) 26,5027,2028,2029,0029,1030,0430,8531,3931,79 Inflation in the USA, CPI1,80%2,50% Source: documents adopted by the Evaluation Committee under the Board of Directors of JSC RAO UES of Russia
