6 4T 12 6 Performance of controlled investments The increase in investments is the result of: ( ) the execution of project UPME , which was completed in the first half of the year, and ( ) the activities associated with the execution of the UPME , UPME , and UPME projects. In addition, there have been activities associated with the modernization of the operating communications system. Technical indicators have been stable and are above the required regulatory minimums, without any penalties assessed against the company.

Debt increased by 1822%. In 2013, the dividend distribution proposal totaled COP 10,804 million which corresponds to 40% of net income.

7 4T 12 7 The rate of growth of operating income and LTM EBITDA was slower than the growth of revenues, principally as a result of: ( ) higher level of depreciation, as a result of the new assets from the expansion projects. Expansion projects increased the level of assets by USD 318 million; ( ) increased costs for personnel and for fuel gas for the direct operation of the compressors; ( ) higher insurance payments as a result of the increased assets and premium increases resulting from the winter cold wave; ( ) higher administrative expenses associated with the debt management operation carried out in 2012 (investment banking commissions, and rating agency and legal fees). It is important to note that the debt management costs were a significant, one-time expense that the company does not expect to recur in Growth in EBITDA for the quarter reflects the impact of the start of operations of Cusiana Phase II. Growth in net income is explained by: ( ) the positive performance of operating income; ( ) and, in largest part, the increase in the exchange difference account as a result of the effect of the appreciation of the peso on the valuation of USD-denominated debt; and ( ) lower financial costs as a result of the debt management operation carried out in March Table N. 10 Calidda s selected indicators F 12 F 11 Var % Number of clients 103,724 64, Operating revenue - COP million 370, , Operating income - COP mm 48,080 45, EBITDA LTM - COP million N.A N.A Net Income - COP 64,448 59, Cálidda s operating income growths as a result of new clients contracted which have generated higher costs of installation services and administration costs.

Emgesa sold 70% of the electricity generated under contracts with terms of one to two years.

This is the result of compliance with new safety regulations for Colombia s power plants and an increase in personnel costs in production areas. During 2012, Emgesa refinanced its debt, significantly lowering its interest expense and extending maturities. Debt also increased in order to finance the El Quimbo project. The financial result benefited from a lower average level of debt during the year and higher interest rates on investment of cash surpluses. The lower level of dividends payable to EEB in 2011 is explained by the fact that at the end of 2010, the company decreed dividends based on an early close of the financial statements (for the period January-September 2010). As a result, dividends decreed in 2011 correspond to results for the period October-December Dividends declared in 2012 correspond to results for the full year The shareholders meeting on March 20, 2013 approved distribution of COP 783,529 million in dividends. EEB s share is COP 404,850 million and will be paid in during 2013/14.

9 4T 12 9 Demand in Codensa s service area grew at a slower rate that for the entire country. The Codensa service area has the highest concentration of industry, and industrial growth was minimal in 2012 (0.7%). National demand growth was in large part the result of mining and oil sector activity in the Caribbean and Eastern regions of Colombia. Table No 15 Capex F 12 F 11 Var % Million COP 241, , Million USD Investments in 2012 were channeled principally to new client service, upgrading circuits, and increasing substation capacity. During 2011, Nueva Esperanza substations was constructed which explains the reduction in investment amount during 2012/11.

Cost of sales grew moderately as a result of increased energy contract purchases to meet growing power demand. The lower dividends in 2012 are explained by the early close of financial statements for the period January-September As a result, dividends distributed in 2012 correspond only to results for the final three months of the year (October- December). The March 21, 2013 shareholders meeting approved distribution of dividends for COP 510,992 million. EEB s share is COP 264,915 million, which will be paid in during 2013/14.

Cost of sales increased principally as a result of increased supply and gas transportation costs. Net income decreased principally as a result of the commissions and banking fees for the bond issuance and a greater expense on the exchange difference account. Colombia s Financial Superintendency authorized the issuance of COP 500,000 million in bonds in order to refinance debt and up to 100% of working capital. On October 24, 2012, the first tranche in the amount of COP 300,000 million was placed via an auction, at terms of five and seven years.

13 4T Footnotes in annex 5 Operating income grew at a slower rate than operating revenues as a result of an increase in the costs for transportation and distribution of natural gas, principally as a result of: ( ) maintenance and repair of the principal network of Cálidda; ( ) increased investments in the connections and installations of Cálidda and Contugas; ( ) increased costs of operation, maintenance, and purchases of fuel gas by TGI; ( ) administrative expenses associated with TGI s debt management operation (investment banking, rating agency, and legal fees). These debt management costs were a significant, one-time expense that the company does not expect to recur in The growth in net income is principally the result of: ( ) the positive performance of operating income, especially in the electricity transmission and natural gas transportation businesses; ( ) higher dividends declared in EEB s favor. In 2011, the non-controlled affiliates declared dividends based only on the period October-December 2010, while in 2012, these dividends were based on the full year 2011; ( ) the exchange difference account, which was a loss in 2011 and a significant gain in This was the result of the effect of the appreciation of the peso on the valuation of foreign currency debt; and ( ) a lower level of financial expense as a result of EEB s and TGI s debt management operations.

The leverage ratio decreased from 2.24 to 1.88 despite the disbursement of Contugas debt for USD 106 million, as a result of: ( ) the more than proportional increase in Consolidated EBITDA; and ( ) a lower level of debt as a result of Exchange rate movements (the Colombian peso appreciated 9% against the dollar in 2012).
