2Q10 Relevant Results Analysis of Consolidated2 Financial Results (In USGAAP) Revenues decreased 25.6% to US$46.1 million in the second quarter 2010 compared to the same period of 2009. This result was driven mainly by US$15.8 in lower electricity sales that resulted from lower contract prices (primarily due to the decrease in coal prices, used as the semiannual escalator of the contracts).

For the first six months of 2010, Revenues totaled US$98.6 million, a decrease of 18.3% compared to the same period of 2009.

This decrease was mainly a result of: (i) lower electricity sales by US$21.9 million, due to lower contracted prices; and, (ii) lower other revenues of US$0.2 million.

Revenues consist of the following:

Operating Costs and Expenses increased 53.5%, in the second quarter of 2010, to US$56.5 million compared to the same period of 2009. This variance was principally a net result of: (i) US$17.1 million of higher coal costs (primarily due to higher generation and higher cost per unit of coal contracted); (ii) higher energy purchases by US$5.5 million basically due to higher energy acquired to meet higher demand, and higher spot prices; (iii) lower depreciation by US$1.1 million; (iv) lower operating and maintenance expenses by US$1.0 million (in June 2009 Itabo had two major maintenances); and, (iii) lower selling, general and administrative expenses by US$0.8 million.

During the first six months of 2010, Operating Costs and Expenses increased 42.6% to US$106.1 million compared to same period of 2009. This variation was mainly caused by the net effect of: (i) higher coal cost by US$22.8 million due to higher generation and higher per unit costs of contracted coal derived from a contract signed in 2008, which is expected to expire in mid 2011; (ii) higher electricity cost by US$13.0 million due to higher demand and higher spot prices; (iii) lower operation and maintenance cost by US$1.9 million, due to the first major maintenance in 2010 started by the end of June while in 2009 both units had had a major maintenance during the same period; (iv) lower selling, general and administrative expenses by US$1.1 million; and, (v) lower depreciation by US$1.1 million.

Total Other Expenses were US$1.8 million in the second quarter 2010 compared to a total other expenses of US$4.3 million in the same period of 2009. This variation was primarily attributable to the net effect of: (i) higher other income by US$1.3 million; (ii) lower net financial expenses by US$0.5 million; (iii) higher net commercial interest income by US$0.4 million; and, (iv) lower exchange expense by US$0.3 million.

For the first six months of 2010, Net Expenses decreased to US$3.7 million, as compared to the Net Expenses recorded in the same period of 2009 of US$6.6 million. This variance was the net result of: (i) lower other expenses by US$3.3 million; (ii) lower net commercial income by US$0.5 million related to lower accounts receivables; and, (iii) lower net financial expenses by US$0.1 million,.

2Q10 Relevant Results Liquidity Collections

Collection Rate

During the second quarter 2010 the average collection rate was 91% against 135% in the same period of 2009. It should be noted that main reason for this variance is that the Q209 collection figures include $54 million of collections, paid in the form of sovereign bonds.

YTD June 30th, 2010, the average collection rate was 121%, against 105% in the same period 2009. This favorable collection rate was primarily due to a loan taken out by the DR Government under the Standby Agreement with the IMF in order to pay their 2009 debts to the generation companies.
