  13. Phase I and II Voting Structure • All persons attending the “RUG-like” group meetings may participate, but may vote only if representing an ERCOT member (“Member”). • For each “RUG-like” group meeting, each Member must designate a representative to vote each of their fractional votes on their behalf. • A representative may only represent multiple fractional votes that belong to a Member or multiple Members in one ERCOT segment as defined below. • Members will be grouped into the same seven segments as those that will apply to the ERCOT Board of Directors in December 2003. Corporate members must vote in their segment. Other members must designate a segment. This designation shall be in force throughout the “RUG-like” group meetings. • Except for the Consumer segment, Members in each segment shall have fractional votes adding up to one per segment. The fractional vote for each Member shall be equal to one divided by the number of Members present and voting in their segment. For example, if a segment has ten Members present and voting, then each Member would have a fractional vote equal to one-tenth. • The Consumer segment will be grouped into three sub-segments – Residential, Commercial and Industrial. Members in each sub-segment shall have fractional votes adding up to one-third per sub-segment. The fractional vote for each Member shall be equal to one-third divided by the number of Members present and voting in their sub-segment. For example, if a sub-segment has three Members present and voting, then each Member would have a fractional vote equal to one-ninth.

  14. Phase I and II Voting Structure • Representation from four of seven segments is required for a quorum. • If 67% or more of the sum of all fractional votes are in favor of a motion, then the motion will pass. • If a motion fails to get a 67% vote, then the Independent Facilitator shall determine if further efforts to get a 67% vote appear achievable within a reasonable time frame. If it is determined that further efforts are not reasonable, then the motion will fail. The Independent Facilitator shall either (i) remand the failed motion to the Coordination Group for further stakeholder work or modification, or (ii) report the failed motion to the Board and TAC as a minority position, or (iii) request urgent resolution by TAC, Board or the Commission. • A proponent of a minority position may request consideration by TAC. TAC may redirect the Independent Facilitator regarding the minority position with notification to the Board.
