Subject: "EOL Country Approval List".

Body: As we discussed, attached is my "Cheat Sheet" which I use to guide me when approving non-US counterparties that come in through EnronOnline via Houston Credit. London Legal and I try to coordinate our responses but I cannot speak for them and the standards they may apply to approving counterparties to trade online. They also frequently deal with different countries than us. You may want to speak to Justin Boyd. Generally, with respect to most physical trading, except power trading, there are no legal restrictions to trading. Most of the restrictions in this list are with respect to financial products. Physical bandwidth has generally not done much legal due diligence outside of the US and the UK and bandwidth is therefore not open to non US and UK counterparties. With physical power, generally, in most countries they require some sort of power marketing license so I look to the power lawyers to guide me. As I also mentioned, for Japan or Australian based counterparties I wait for David Minns or Jane McBride to advise me.
