Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in section 3 of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29), 412 or 430(k) of the Code or section 4068 of ERISA, other than such liabilities or Liens as would not be individually or in the aggregate material.

Since March 31, 2010, there has been no material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Indebtedness of the Company, a Member, New Owner or New Operator. None of the Company, a Member, New Owner or New Operator is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any of its Indebtedness and no event or condition exists with respect to any of its Indebtedness that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its regularly scheduled dates of payment.

(b) The Company has not agreed or consented to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired, to be subject to a Lien not otherwise permitted by Section 10.5.

(c) The Company is not a party to, nor otherwise subject to any provision contained in, any instrument evidencing Indebtedness of the Company, any agreement relating thereto or any other agreement (including, but not limited to, its charter or other organizational document) which limits the amount of, or otherwise imposes restrictions on the incurring of, Indebtedness of the Company, other than the 2009 Note Agreement and the RBC Agreement.

Section 5.17 Foreign Assets Control Regulations, Etc. (a) Neither the sale of the Notes by the Company hereunder nor the use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto.

(b) None of the Company, the Members, New Owner or New Operator: (i) is a Person described or designated in the Specially Designated Nationals and Blocked Persons List of the Office of Foreign Assets Control or in Section 1 of the Anti-Terrorism Order or (ii) engages in any dealings or transactions with any such Person. The Company, each Member, New Owner and New Operator is in compliance, in all material respects, with the USA Patriot Act.

(c) No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for any payments to any governmental official or employee, political party, official of a political party, candidate for political office, or anyone else acting in an official capacity, in order to obtain, retain or direct business or obtain any improper advantage, in violation of the United States Foreign Corrupt Practices Act of 1977, as amended, assuming in all cases that such Act applies to the Company and the Members.

SCHEDULE A-12

(To Note Purchase Agreement)

(b) Neither the Company nor either Member is a “public utility” under the FPA and the regulations of FERC thereunder. The execution, delivery and performance of the Company’s and Sharyland’s obligations under the Transaction Documents requires no authorization of approval by, or notice to, and is not subject to the jurisdiction of, FERC under the FPA.

(c) Sharyland and the holding company system of which it is a part have obtained a waiver of the requirements of 18 C.F.R. 366.21, 366.22 and 366.23 (FERC Docket No. PH06-59-000), but are subject to the FERC regulations relating to regulatory access to books and records. Sharyland and the holding company system of which it is a part have filed a notice of holding company status under FERC Docket No. HC06-1-000 and may be required to submit a revised notice of holding company status and/or a revised request for the waiver described in the preceding sentence as a result of the transactions contemplated in the Transaction Documents or in Schedule 10.1. Under FERC’s currently effective regulations, the Company will be deemed not to be a “public-utility company” and as a result TDC is not a “holding company” under PUHCA; as a result of the Cap Rock Transactions, Sharyland will become a “holding company” under PUHCA.

(d) The Company is subject to regulation as an “electric utility” by the Public Utility Commission of Texas. The execution, delivery and performance of the Company’s and Sharyland’s obligations under the Transaction Documents requires no authorization or approval by, or notice to, the Public Utility Commission of Texas or under the Public Utility Regulatory Act of Texas other than those that have been obtained.

(e) Solely by virtue of the execution, delivery and performance of the Transaction Documents, no Purchaser will become subject to any of the provisions of the FPA, PUHCA (based on FERC’s currently effective definitions under PUHCA) or the Public Utility Regulatory Act of Texas, or to regulation under any such statute.

(b) The Company has no knowledge of any facts which would give rise to any claim, public or private, of violation of Environmental Laws or damage to the environment emanating from, occurring on or in any way related to real properties now or formerly owned, leased or operated by the Company, either Member, New Owner or New Operator or to other assets or its use, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect.

(c) None of the Company, a Member, New Owner or New Operator has stored any Hazardous Materials on real properties now or formerly owned, leased or operated by any of them and has not disposed of any Hazardous Materials in a manner contrary to any Environmental Laws in each case in any manner that could reasonably be expected to result in a Material Adverse Effect; and

SCHEDULE A-13

The security interests in the Collateral granted to the Collateral Agent (for the benefit of the Secured Parties) pursuant to the Financing Documents: (a) constitute as to personal property included in the Collateral and, with respect to subsequently acquired personal property included in the Collateral, will constitute, a perfected security interest and Lien under each applicable Uniform Commercial Code, and (b) are, and, with respect to such subsequently acquired property, will be, as to Collateral perfected under each applicable Uniform Commercial Code, superior and prior to the rights of all third Persons now existing or hereafter arising whether by way of mortgage, lien, security interests, encumbrance, assignment or otherwise, except for Permitted Liens. All action as is necessary has been taken to establish and perfect the Collateral Agent’s rights in and to, and the first lien priority of its Lien on, the Collateral, including any recording, filing, registration, delivery to the Collateral Agent, giving of notice or other similar action. The Security Documents and financing statements relating thereto have been duly filed or recorded in each office and in each jurisdiction where required in order to create and perfect the Lien and security interest described above and the priority thereof.

SCHEDULE A-21

(To Note Purchase Agreement)

Section 8.6 Yield-Maintenance Amount.

“Yield-Maintenance Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Yield-Maintenance Amount may in no event be less than zero. For the purposes of determining the Yield-Maintenance Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by (i) the yields reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

In the case of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury ▇▇▇▇ quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

SCHEDULE A-22

(To Note Purchase Agreement)

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1.

“Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

Section 9.5 Existence, Etc. The Company will at all times preserve and keep in full force and effect its limited liability company existence and all rights and franchises of the Company unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise could not, individually or in the aggregate, have a Material Adverse Effect.

SCHEDULE A-44

(To Note Purchase Agreement)

notice of such transfer, any reference to such Affiliate as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Affiliate, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an original Holder of the Notes under this Agreement.

SECTION 22. MISCELLANEOUS.

Section 22.1 Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent Holder of a Note) whether so expressed or not.

Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.4 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Yield-Maintenance Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day.

Section 22.5 Construction, etc. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

Exhibit 2

Page 3

3.1.1

the System Lease Obligations shall first be irrevocably and indefeasibly paid in full to the Entitled Party before any of the Subordinated Lenders shall be entitled to receive any payment (other than Reorganization Securities) on account of the Subordinated Indebtedness whether in cash, securities or other assets (other than Reorganization Securities); and

3.1.2

any payment or distribution of assets of Sharyland of any kind or character in respect of the Subordinated Indebtedness to which any of the Subordinated Lenders would be entitled if the Subordinated Indebtedness were not subordinated pursuant to the terms hereof shall be made by the trustee, liquidator or agent or other Person making such payment or distribution, directly to the Entitled Party until the System Lease Obligations are paid in full and each of the Subordinated Lenders and, unless the Company is the Entitled Party, the Company irrevocably authorizes and empowers the Entitled Party to receive and collect on its behalf any and all such payments or distributions.

3.2

The Subordinated Lenders agree not to, directly or indirectly, initiate, prosecute or participate in any claim, action or other proceeding (a) challenging the enforceability, validity or priority of the System Lease Obligations or (b) to enforce payment of the Subordinated Indebtedness in violation of these subordination provisions.

Section 4. Incorrect Payments. If, for any reason whatsoever and whether pursuant to an Insolvency Proceeding or otherwise, Sharyland shall make or any of the Subordinated Lenders shall receive any payment or distribution of any kind or character, whether in cash, securities or other property (other than Reorganization Securities), on account or in respect of the Subordinated Indebtedness in contravention of any of the terms set forth herein, such Subordinated Lender shall hold any such payment or distribution in trust for the benefit of the Secured Parties, promptly notify the Entitled Party of the receipt of such payment or distribution and promptly pay over or deliver such distribution or payment to the Entitled Party or to any other Person nominated by the Entitled Party, to hold for the account of the Secured Parties.

Section 5. Non-Impairment. To the fullest extent permitted by applicable Law, no change of law or circumstances shall release or diminish any of the Subordinated Lender’s obligations, liabilities, agreements or duties hereunder, or affect the provisions set forth herein in any way.

Section 6. Benefit of Subordination Provisions. These subordination provisions are intended solely to define the relative rights of the Secured Parties, the Collateral Agent, the Company, the Subordinated Lenders, and their respective successors and permitted assigns.

Section 7. Termination and Reinstatement. Notwithstanding anything to the contrary contained herein, the Subordinated Indebtedness shall no longer be subordinated in right of liquidation pursuant to the terms contained herein otherwise at such time as the Obligations (other than contingent obligations for which no claim has been made) shall have been indefeasibly paid in full in cash and any commitments to lend under any Permitted Secured Indebtedness shall have terminated. If any payment to any of the Entitled Party, the Company, the Collateral Agent or the Secured Parties by Sharyland or any other Person in respect of any of the System Lease Obligations is held to constitute a preference or a voidable transfer under applicable Law, or if for any other reason any such party is required to refund such payment to Sharyland or to such Person or to pay the amount thereof to any other Person, each Subordinated Lender agrees and acknowledges that the provisions set forth herein shall continue to be effective or shall be reinstated, as the case may be, to the extent of any such payment or payments.

Section 8. Restrictions on Transfers. None of the Subordinated Lenders may transfer (by sale, novation or otherwise) any of its rights or obligations under the Subordinated Indebtedness unless the transferee of such interest first agrees in writing to be bound by the terms of this Exhibit G applicable to the transferor of such interest and executes an instrument to that effect.

Section 9. Exercise of Powers.

9.1	The Entitled Party shall be entitled to exercise their rights and powers under these subordination provisions in such a manner and at such times as the Entitled Party in its absolute discretion may determine.

9.2	The Subordinated Lenders alone shall be responsible for their contracts, engagements, acts, omissions, defaults and losses and for liabilities incurred by them.
