Appointments of Agents and Attorneys in Fact

I would like to do fewer resolutions authorizing non-vps to sign contracts,
and when we need such authorizations, let's make sure the resolutions are
appropriately limited. My thoughts are as follows:

1. We have a lot of vps that can sign contracts.
2. It is generally ok to have confirmations signed by certain carefully
selected directors since we are confirming a trade that already took place
and there is master agreement already signed.
3. There are certain very routine agreements like pipeline right-of-way
agreements that are ok for carefully selected directors to sign.
4. Confidentiality agreements should be signed by a vp.
5. Any authorization for a director to sign should expire within not more
than one year and revoke all prior authorizations.

Please give me your comments.
