Comstar UTS reported 33% year on year consolidated revenue growth to US$ 286.6 million for the second quarter of 2006, compared to US$ 214.9 million for the second quarter of 2005. Traditional segment delivered another quarter of solid performance, while Alternative business segment growth benefited from the expanding broadband offering to residential subscribers, which contributed strongly to the overall segment revenue growth. Regional operations added US$ 9.8 million to the Group revenue. Additionally MGTS received a compensation of US$ 17.8 million from the federal budget to MGTS for the reimbursement of discounts on installation and monthly fees to certain categories of residential subscribers, such as pensioners and military veterans, granted according to the applicable legislation prior to January 01, 2005. Thus the 33% revenue growth consisted of 21% organic growth, 4% growth from acquisitions and 8% growth from the abovementioned contribution.

Group OIBDA increased by 30% year on year to US$ 115.0 million for the three months ended June 30, 2006 with OIBDA margin decreasing year on year to 40.1%.

The Group's operating income was up 34% year on year to US$ 88.1 million with operating margin up year on year to 30.8%. It included federal budget compensation as above and a net gain of US$ 7.6 million on the disposal of assets, held for sale, namely an MGTS switching center subsequently renovated in cooperation with the co-investor and sold to a third-party. This sale was executed in line with the Company's strategy of divesting non-core assets.

Consolidated net income for the second quarter of 2006 has almost tripled year on year to US$ 58.2 million.

Net cash provided by operating activities during the second quarter of 2006 was US$ 80.1 million. The increase of 48% year on year was primarily related to the compensation received from the budget, organic business growth and acquisition of subsidiaries in the regions.

Total CAPEX grew by 36% year on year and by 56% quarter on quarter to US$ 82.2 million for the second quarter of 2006.

Alternative segment revenues including inter-segment sales were up 24% year on year to US$ 103.3 million. Revenue from the residential broadband internet services under the brand Stream doubled year on year to US$ 19.4 million. The Group's regional businesses contributed US$ 9.8 million to total revenues, which represented a 390% growth year on year.

Revenues from residential subscribers grew by 57% year on year to US$ 23.4 million. This growth reflected continued increase in the residential subscriber base of broadband Internet under the Stream brand, which accounted for 83% of total residential revenues or US$ 19.4 million in the second quarter of 2006 compared to 64% or US$ 9.5 million a year ago. The introduction of the bundled tariff offer in May 2006 has stimulated the growth in new subscribers over a seasonally slow summer period. The total number of broadband subscribers increased by 126,927 to 301,045 customers during the second quarter of 2006, which represented a 73% growth year on year. Average revenue per ADSL line excluding connection fee (ARPL) increased 29% year on year to US$ 21.6 in the second quarter of 2006 from US$ 16.7 for the same period last year. It had a positive contribution from the introduction of new tariff plans and additional services such as pay TV, bundled offer (broadband internet and pay TV) and the launch of multimedia services, including gaming portals and radio channels.

Revenues from corporate subscribers in the Alternative segment were up 10% year on year to US$ 40.5 million. Revenue from data and Internet services was up 21% as a result of growing demand for such services in Moscow.

[TABLE OMITTED]

Traditional segment revenues including inter-segment sales were up 31% year on year to US$ 209.6 million.

Residential subscriber revenues in the segment were up 46% year on year to US$ 88.9 million, including the compensation from federal budget of US$ 17.8 million to MGTS for the discounts granted to certain categories of residential subscribers of MGTS prior to January 1, 2005. This payment was recognized as revenue upon cash collection.

Residential subscriber revenues in the traditional segment benefited from an increase in regulated tariffs. Monthly subscription fee for residential subscribers was raised in October 2005 from RUR 170 (or approximately US$ 6.33) to RUR 200 (or approximately US$ 7.43).

Corporate subscriber revenues were up 8% year on year to US$ 52.9 million primarily driven by the increase in line rentals.

Revenues from operators grew by 35% year on year to US$ 67.8 million largely due to the increase in number of access nodes and increased unregulated tariffs for using MGTS infrastructure.

Attachment A

NON-GAAP FINANCIAL MEASURES

This results statement includes financial information prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP), as well as other non-GAAP financial information. The non-GAAP financial information should be considered as an addition to, but not as a substitute for, information prepared in accordance with US GAAP.

OIBDA is operating income before depreciation and amortisation, and the OIBDA margin is defined as OIBDA as a percentage of net revenues. These measures are included in this results statement in order to provide additional information regarding the Group's ability to meet future debt service payments, capital expenditure and working capital requirements, and as a metric to evaluate profitability. OIBDA is not a measure of financial performance under US GAAP, and is not an alternative to net income as a measure of operating performance, or to cash flows from operating activities as a measure of liquidity. While depreciation and amortisation are considered operating costs under US GAAP, these items primarily represent the non-cash current period allocation of costs arising from the acquisition or development of long-term assets in prior periods. OIBDA is commonly used as a criterion for evaluation of operating performance by credit and equity investors and analysts. The calculation of OIBDA may be different from the calculation used by other companies and comparability may therefore be limited. OIBDA can be reconciled to the Group's consolidated statements as follows:

[TABLE OMITTED]

ARPL (Monthly Average Revenue per Line), a non-US GAAP financial measure, is calculated for the relevant period by dividing Comstar UTS' Stream service revenue, including broadband internet, pay TV and bundled offering excluding connection fee, for that period by the average monthly number of the Comstar UTS' broadband subscribers during the period and by the number of months in the period. Reconciliation of ARPL to service revenues, the most directly comparable US GAAP financial measure, is presented below. We believe that ARPL provides useful information to investors because it is an indicator of the performance of the Company's business operations and assists management in budgeting. The Company also believes that ARPL provides management with useful information concerning usage and acceptance of the Company's services. ARPL should not be viewed in isolation or as an alternative to other figures reported under US GAAP.

CAPEX (Capital Expenditures) is cash expended for purchases of property, plant and equipment and intangible assets, and non-cash additions of property, plant and equipment and intangible assets. CAPEX can be reconciled to the Group's consolidated statements as follows:
