        <Explanation>Transfer of Net Assets- For part of the 2010 tax year, ERCOT was organized with a functionally independent division known as Texas Regional Entity (TRE). TRE was formed on April 19, 2007, for two primary reasons: (1) to become a regional entity under Part II of the Federal Power Act (16 U.S.C. 824, et seq.) through a delegation agreement with North American Electric Reliability Corporation (NERC) which was approved by the Federal Energy Regulatory Commission (FERC), pursuant to Section 215 of the Federal Power Act; and (2) to perform certain reliability compliance monitoring and reporting duties for the Public Utility Commission of Texas (PUCT), an agency of the State of Texas. On January 1, 2010, Texas Reliability Entity, Inc. (Texas RE), a Section 501(c)(3) tax-exempt, Texas non-profit corporation, was formed to become the successor regional entity for the ERCOT region. ERCOT and Texas RE entered into an assignment and assumption agreement, effective as of June 30, 2010, to allow Texas RE to take over all of the activities and responsibilities which were then performed by TRE. Effective July 1, 2010, NERC entered into an Amended and Restated Delegation Agreement with Texas RE, designating Texas RE the new regional entity for the ERCOT region. Texas RE is a separate, unaffiliated legal entity from ERCOT. From July 1, 2010, through December 31, 2010, at the PUCT's direction, ERCOT, Texas RE and the PUCT entered into a tri-party professional services agreement and statement of work for ERCOT region reliability monitor services (Reliability Monitor Agreement) subject to the PUCT's supervision and oversight in the total amount of $413,730. In this role, Texas RE was responsible for monitoring, investigating, auditing and reporting to the PUCT regarding compliance with the reliability-related ERCOT Protocols and Operating Guides, and the reliability-related provisions of the Public Utility Regulatory Act by ERCOT and ERCOT market participants. The parties entered into this Reliability Monitor Agreement pursuant to the PUCT's directive that a third-party entity independent of ERCOT and ERCOT market participants assist the PUCT in ensuring compliance and enforcement of the reliability-related rules arising from state law and ERCOT Protocols and Operating Guides. In addition, Texas RE provided other reliability-related subject matter expert advice, expertise, and assistance to the PUCT in the conduct of the PUCT's oversight and enforcement activities. The parties have renewed the Reliability Monitor Agreement for a three-year extension from January 1, 2011 through December 31, 2013 for a total not-to-exceed amount of $3.975 million. The services provided by Texas RE under the Reliability Monitor Agreement are separate and in addition to the services performed by Texas RE as a regional entity pursuant to its Amended and Restated Delegation Agreement with NERC. From January 1, 2010, through June 30, 2010, Larry Grimm served as Chief Executive Officer (CEO) and Chief Compliance Officer of TRE while TRE was an independent division of ERCOT. Mr. Grimm served as President and CEO of Texas RE from January 18, 2010, through December 31, 2010. During the 2010 tax year, Sheri Givens, Public Counsel with the Texas Office of Public Utility Counsel (OPUC), served as an ex officio voting director, representing residential and small commercial electricity consumers, on the ERCOT Board of Directors. During this time, Ms. Givens as Public Counsel with the Texas OPUC (or another employee as designated by Ms. Givens) also concurrently served as an ex officio non-voting director, representing residential and small commercial electricity consumers, on the TRE and Texas RE Boards of Directors. During the 2010 tax year, Barry T. Smitherman, the Chairman of the PUCT, served as an ex officio non-voting director on the ERCOT Board of Directors. During this time, Mr. Smitherman as the Chairman of the PUCT or another PUCT Commissioner designated by the Chairman could serve on as an ex-officio non-voting member; and Donna Nelson, PUCT Commissioner, routinely served on the TRE and Texas RE Boards of Directors in this capacity. In addition, from April 2007 through April 2010, the members of the ERCOT Board of Directors also concurrently served on the TRE Board of Directors. From January 2010 until June 30, 2010, five ERCOT Directors served on the Texas RE Board of Directors with Mr. Grimm as formation directors - specifically, Jan Newton as Chair, Michehl Gent as Vice-Chair, and Miguel Espinosa, PUCT Chairman Smitherman and Ms. Givens as the remaining formation directors.</Explanation>

Six of the voting directors represent segments of participants in the electricity market; each such "market participant director" has an elected alternate (segment alternate) who can attend meetings in the absence of the market participant director and vote on the absent market participant director's behalf in the event that such market participant director cannot attend a board meeting.</Explanation>

        <Explanation>Management Duties- Roy Bowman served as the ERCOT Interim Chief Financial Officer for a portion of 2010, that is, through May 14, 2010. Beginning in September 2009, ERCOT contracted these services directly through Tatum LLC, where Roy Bowman serves as a partner. In 2010, ERCOT paid Tatum, pursuant to contract, $166,333 for the services provided by Roy Bowman. As this was not W-2 reportable compensation from ERCOT and was paid directly to a management company, this amount is not included in Part VII, Line 1a, Schedule J-2, Part I, Column D, or Schedule J, Part II, Column B. Prior to the 2010 tax year, ERCOT engaged the law firm of Casey, Gentz and Magness, LLP (CGM), for legal services related to various regulatory matters, including rate case matters. From January 1, 2010 through April 12, 2010, CGM provided legal services to ERCOT related to various legal regulatory matters for which ERCOT paid CGM a total of $103,458 in legal fees. Due to the voluntary departure of Michael G. Grable as ERCOT Vice President, General Counsel and Corporate Secretary, effective on April 12, 2010, ERCOT entered into a professional services agreement and statement of work with CGM for the part-time services of Bill Magness, a named partner of CGM, to serve as ERCOT Interim Vice President, General Counsel and Corporate Secretary for an initial term of April 12, 2010 through July 4, 2010. On April 12, 2010, the ERCOT Board of Directors ratified Mr. Magness as an ERCOT officer with the title of Interim Vice President, General Counsel and Corporate Secretary pursuant to ERCOT's agreement with CGM for Mr. Magness' services to avoid any disruption in the operations of ERCOT. Such ratification was expressly in effect until the earlier of the filling of this officer position by ERCOT or the termination of ERCOT's agreement with CGM for Mr. Magness' services. On June 14, 2010, ERCOT and CGM amended the initial statement of work to convert the fee structure from a flat fee to an hourly rate and to amend the end date of the term to June 30, 2010. ERCOT paid a total of $48,701 in legal fees to CGM for Mr. Magness' interim General Counsel services pursuant to this first statement of work for the period of April 12, 2010 through June 30, 2010, and a total of $6,320 in legal fees to CGM for other regulatory matters, including legal services performed by Mr. Magness, for the same time period. ERCOT and CGM entered into a second statement of work for an increased hourly rate and for a new term of July 1, 2010 through September 30, 2010. ERCOT paid a total of $117,829 in legal fees to CGM for Mr. Magness' interim General Counsel services pursuant to this second statement of work for the period of July 1, 2010 through September 20, 2010, and a total of $1,185 in legal fees to CGM for other regulatory matters, including legal services performed by Mr. Magness, for the same time period. On September 21, 2010, Mr. Magness resigned from CGM and accepted employment with ERCOT. On the same date, the ERCOT Board of Directors ratified Mr. Magness as an ERCOT officer with the title of Vice President, General Counsel and Corporate Secretary for a term not to exceed one year. During the 2010 tax year, ERCOT paid a total of $277,493 in legal fees (exclusive of expense reimbursements) to CGM, specifically, $166,530 for Mr. Magness' services as interim General Counsel from April 12, 2010, through September 20, 2010, and $110,963 for other legal fees for which Mr. Magness provided legal services from January 1, 2010 through September 20, 2010.</Explanation>

With respect to each of the six Market Participant Directors, only the Corporate Members of the Membership Segment represented by the Market Participant Director are allowed to elect the Director and the Segment Alternate for that seat. There are three Consumer Directors, of which: (i) one is the Public Counsel, an ex officio voting member of the Board representing residential consumers and small commercial consumers; (ii) one is selected by the Large Commercial Consumer Corporate Members; and (iii) one is elected by the Corporate Members of the Industrial Consumer subsegment. The Membership votes by segment to elect the five unaffiliated voting Directors. The remaining voting Director is the Chief Executive Officer of ERCOT, who is an ex officio voting member of the Board.</Explanation>

        <Explanation>Process to monitor and enforce conflicts of interest- Each Director and Segment Alternate annually must execute an Ethics Agreement for Directors and Segment Alternates, and each employee annually must attend internal training sessions and execute an Employee Ethics Agreement. Pursuant to each Ethics Agreement, a signatory has an affirmative duty to disclose any actual or potential conflicts of interest of the signatory (and his or her employer, in the case of Director or Segment Alternates), and also must disclose all personal relationships with ERCOT vendors, including business or direct or indirect ownership interests. Any conflict of interest issue involving a Director or Segment Alternate is referred to the ERCOT General Counsel who, in consultation with the Board Chair and outside legal counsel, if and when necessary, makes a legal determination as to whether a conflict exists and, if so, a recommendation as to how it may be resolved. Any conflict and its resolution are reported to both the Human Resource &amp; Governance (HR&amp;G) Committee of the Board and the full Board of Directors. Any objection to the recommendation is resolved by the HR&amp;G Committee or the full Board. Any ERCOT employee conflicts are evaluated by the ERCOT legal staff, and the legal staff makes a recommendation to resolve the conflict of interest. If the ERCOT legal staff recommends a resolution that is objectionable to the manager/director/officer of the conflicted employee, the legal decision is referred to the Chief Executive Officer and ultimately to the Board's HR&amp;G Committee.</Explanation>

        <Explanation>1) Process for determining compensation of the Chief Executive Officer- In determining compensation for the Chief Executive Officer, ERCOT follows a procedure which ensures that (i) compensation is approved in advance by the independent members of the Board of Directors and its HR&amp;G Committee, (ii) the Board and the HR&amp;G Committee obtains and relies upon appropriate data for comparability, and (iii) the Board and the HR&amp;G Committee each adequately documents the basis for its respective determination. In practice, the HR&amp;G Committee of the Board of Directors reviews proposed changes to Chief Executive Officer compensation and submits recommendations to the Board for its approval. In its review, the HR&amp;G Committee can request information from independent compensation consultants, and they receive information annually in regards to the compensation levels of similar companies from Forms 990 and other sources. Additionally, compensation surveys/studies are performed, as needed, to provide insight into the elements of compensation. The compensation-related information and Committee recommendations are submitted to the Board of Directors for its consideration and approval. A review of the Chief Executive Officer's compensation is performed annually, and all decisions regarding the Chief Executive Officer's compensation are documented and maintained. 2) Process for determining compensation of officers- In determining compensation for officers other than the Chief Executive Officer, ERCOT follows a procedure which ensures that (i) compensation is fully disclosed in advance to independent members of the Board's HR&amp;G Committee, (ii) the HR&amp;G Committee obtains and relies upon appropriate data for comparability, and (iii) the HR&amp;G Committee adequately documents the basis for its determination. The Chief Executive Officer reports proposed officer pay amounts to the HR&amp;G Committee for review and comment before any merit increase is finalized. Key employee compensation is reviewed and determined by their appropriate officer. For review of officer and key employee compensation, ERCOT uses merit ratings and data obtained relating to comparable compensation of similarly qualified persons in comparable positions at comparable organizations, including compensation surveys and Forms 990. Officer and key employee compensation is reviewed annually, and all decisions regarding officer and key employee compensation are documented and maintained.</Explanation>
