3. What is the Standards of Conduct? 18 Code of Federal Regulation (CFR) Part 358 3

4. Federal Energy Regulatory Commission (FERC) Regulates transmission service for power transactions Regulates wholesale power sales Regulates hydroelectric licensing and operations 4

5. FERC Regulations In 2004, the Federal Energy Regulatory Commission (FERC) issued regulations regarding Standards of Conduct for Public Utility Transmission Providers which apply to the APGI transmission divisions of Yadkin, Tapoco, Colockum & Long Sault. Since AGC Warrick division & the APMLLC/APGI marketing affiliates are subsidiaries of APGI, it’s important to understand the responsibility of the transmission groups and interactions with the other APGI divisions or subsidiaries. FERC is trying to promote fair competition among companies that sell electricity. There is concern that some companies having both transmission providers and electricity sellers, may have allowed their sales employees access to transmission information that was not readily available to competing sellers. This could give a company’s sales staff a competitive edge over other sales groups. 5

6. FERC Regulations FERC’s Standards of Conduct applies to Public Utilities to govern the relationship between regulated Transmission Providers and their Energy Affiliates. It ensures that Transmission Providers cannot extend their market power over transmission to wholesale energy markets by giving Energy Affiliates undue preferential treatment. The next slide shows Alcoa Power Generating Inc.(APGI), a FERC regulated public utility. Alcoa created APGI to house our electric assets of generation and transmission in order to keep them separate from Alcoa Inc. APGI has 5 divisions and 2 wholly-owned subsidiaries. Of the 5 divisions, FERC recognizes Long Sault, Tapoco, Colockum and Yadkin as transmission owners. The slide shows that our marketing groups were outsourced to Cargill Power Marketing LLC as of 4/1/14. Cargill must be treated as a contractor on the Energy Marketer side of the Standards of Conduct. Make sure that NO transmission information flows to this contractor or the other APGI marketing arms that is not already public information. 6
