3. 3 ERCOT along with other ISO/RTOs began a conversation with CFTC last year to discuss applying for an exemption from CFTC jurisdictional oversight of ISO/RTO markets –Potential requirements of ISO/RTOs for obtaining CFTC exemption FERC Credit Rule – The CFTC preliminarily seems to view favorably the requirements of the FERC Credit Rule While not under FERC Jurisdiction, compliance with the FERC Order helps ERCOT make progress towards the exemption –Dodd Frank becomes effective incrementally in the second half 2011; CFTC exemption must be obtained within a comparable timeframe –CFTC exemption may be contingent on ERCOT making changes to existing Protocols, systems, etc. in a timely manner COPSJune 14, 2011 CFTC 4(c) Exemption

4. 4 FERC Credit Rule and ERCOT Rules Shortening Settlement Cycle FERC Rule 14 Days; Billing periods of no more than seven days and settlement periods of no more than seven days after issuance of bills. ERCOT Rule Day Ahead Market settlement cycle is consistent with FERC Credit Rule (with possible exception of certain holiday periods); Real Time settlement cycle 21-31 days, including payment cycle (NPRR 347 in process reduces this to 14-21 days ); Other monthly billings Potential Changes Required to be Consistent with FERC Rule Reduce settlement cycle to 14 days, billing periods of no more than seven days and settlement periods of no more than seven days after issuance of bills –Change to ERCOT Protocols –System change COPSJune 14, 2011

5. 5 Impact of NPRR 347 NPRR 347 will –Reduce the number of days in the settlement process by eliminating the lag between real time settlement statements and invoicing –Eliminate 2 bank business days from the payment process –Invoice activity for DAM and RTM (I/F/TU) settlements posting on the same day into a single invoice which posts on that same day After NPRR 347, ERCOT anticipates (based on 2011 calendar), that approximately 82% of operating days will be settled within 16 days and the weighted average days to settle will be approximately 16 days COPSJune 14, 2011

7. 7 Additional actions to consider Reduce RTM Initial Settlement from 10 days to 9 days –Leave Data Aggregation on OD + 7 (same as current) –This change shortens the schedule but still minimizes the impact to processes and/or accuracy Reduce the payment timeline for the single daily Settlement Invoice (includes DAM and RTM activity) from 3 to 2 Bank Business Days –This change has an impact on ability to use ACH With the above changes (in addition to the changes in NPRR347), ERCOT anticipates (based on 2011 calendar), that approximately 88% of operating days will be settled within 14 days and the weighted average days to settle will be approximately 13.5 days (remaining 12% impacted by weekends and/or holidays falling within the cycle) COPSJune 14, 2011

10. 10 Reduce payment timeline from 3 to 2 bank business days Tightening the payment timeline will impact the ability to use ACH as a payment mechanism –Impact is noted on the following page Consider elimination of ACH as a payment option –The CFTC expectation is that “money settlements are final when effected” (e.g. “good funds”). ACH transactions do not meet this requirement. –Also, ACH transactions can be reversed at the CPs discretion within 5 days of transaction (2 day prepayment based on expectation that reversals may occur only within 2 days), creating credit risk COPSJune 14, 2011
