In preparing the Proposed Final Closing Balance Sheet and the Statement of Proposed Final Closing Adjustment Amount, the Purchaser shall be entitled to access during normal business hours, and in a manner so as not to interfere with normal operations, to all relevant books and records to the extent relating to the Company and personnel of the Seller Parties and their respective Representatives. The Proposed Final Closing Balance Sheet shall reflect the total assets, liabilities (including the outstanding balance of the RBS Debt prior to the repayment thereof (the “Proposed Final Closing RBS Debt”)) and equity (the “Proposed Final Closing Equity Book Value” and, together with the Proposed Final Closing RBS Debt and the Proposed Final Closing Adjustment Amount, the “Proposed Final Closing Amounts”) of the Company as of 12:01 a.m. Eastern Standard Time on the Closing Date, and shall be prepared in accordance with IFRS on a basis consistent with the Reference Balance Sheet, except that (i) medical and dental claims under Seller Plans described in Section 7.4(c)(ii) and Section 7.4(c)(iii) will not be reflected, and (ii) if the MTM Valuation Threshold is satisfied as of the Closing Date, the value of the ERCOT Positions shall be adjusted according to the ERCOT Nodal Methodology.

(b) Seller Parents will have ninety (90) days following delivery of the Proposed Final Closing Balance Sheet and the Statement of Proposed Final Closing Adjustment Amount during which to notify the Purchaser in writing (the “Notice of Objection”) of any objections to the preparation of the Proposed Final Closing Balance Sheet, the Statement of Proposed Final Closing Adjustment Amount or the calculation of any of the Proposed Final Closing Amounts, setting forth in reasonable detail the basis of its objections and, if practical, the U.S. dollar amount of each objection. Matters as to which the Seller Parents may disagree shall be limited to whether (x) the Proposed Final Closing Balance Sheet delivered by the Purchaser is accurate and was prepared in accordance with IFRS on a basis consistent with the Reference Balance Sheet (provided that (i) medical and dental claims under Seller Plans described in Section 7.4(c)(ii) and Section 7.4(c)(iii) will not be reflected, and (ii) if the MTM Valuation Threshold is satisfied as of the Closing Date, the value of the ERCOT Positions shall be adjusted according to the ERCOT Nodal Methodology) and (y) the Statement of Proposed Final Closing Adjustment Amount accurately reflects the Closing Adjustment Amount after giving effect to any accruals in respect thereof on the Proposed Final Closing Balance Sheet (as such accruals may be adjusted pursuant to this Section 2.5(b) and Section 2.5(c)), and Seller Parents shall not be entitled to submit disagreements on any other basis. In reviewing the Proposed Final Closing Balance Sheet and the Statement of Proposed Final Closing Adjustment Amount, each of the Seller Parents shall be entitled to access during normal business hours, and in a manner so as not to interfere with normal operations, to all relevant books and records and personnel of the Purchaser (and any of its permitted assignees hereunder), the Seller and the Company and their respective Representatives to the extent any Seller Parent reasonably requests such information and access to complete its review of the Proposed Final Closing Balance Sheet and the Statement of Proposed Final Closing Adjustment Amount. If the Seller Parents fail to deliver a Notice of Objection in accordance with this Section 2.5(b), the Proposed Final Closing Balance Sheet and the Statement of Proposed Final Closing Adjustment Amount, together with the Purchaser’s calculation of the Proposed Final Closing Equity Book Value, the Proposed Final Closing RBS Debt and the Proposed Final Closing Adjustment Amount reflected thereon, shall be conclusive and binding on all Parties and they shall become the “Final Closing Balance Sheet”, “Final Closing Equity Book Value”, the “Final Closing RBS Debt” and the “Final Closing Adjustment Amount” (and the Final Closing Equity Book Value, the Final Closing RBS Debt and the Final Closing Adjustment Amount, collectively, the “Final Closing Amounts”). Matters included in the calculations in the Proposed Final Closing Balance Sheet and the Statement of Proposed Final Closing Adjustment Amount to which no Seller Parent objects in any Seller Parent’s Notice of Objection shall be deemed accepted by the Seller Parents and shall not be subject to further dispute or review. If any Seller Parent submits a Notice of Objection, then (i) for twenty (20) Business Days after the date upon which the Purchaser receives the Notice of Objection, the Purchaser and the Seller Parents will each use their commercially reasonable efforts to agree on the calculation of each of the Final Closing Amounts that is in dispute and (ii) failing such agreement within twenty (20) Business Days of such notice, the matter shall be resolved in accordance with Section 2.5(c).

(c) If the Purchaser and the Seller Parents have not agreed on all of the Final Closing Amounts within twenty (20) Business Days after delivery of a Notice of Objection, then the Purchaser and the Seller Parents, acting jointly, shall have the right to deliver notice to the other Parties of their intent to refer the matter for resolution to KPMG LLP or such other

international accounting firm as the Parties shall otherwise agree (the “Accounting Expert”). Within ten (10) Business Days of the delivery of such notice, the Purchaser and the Seller Parents shall each deliver to the other Parties hereto and to the Accounting Expert a notice setting forth in reasonable detail their calculation of each of the disputed Final Closing Amounts. The Parties shall instruct the Accounting Expert to consider only those items and amounts set forth in the Proposed Final Closing Balance Sheet and the Statement of Proposed Final Closing Adjustment Amount to which any Seller Parent has disagreed pursuant to a Notice of Objection and for which the Purchaser and the Seller Parents have not resolved their disagreement. Within fifteen (15) Business Days after receipt thereof, the Accounting Expert shall determine its best estimate of the calculation of each of the disputed Final Closing Amounts and provide a written description of the basis for such determination; provided, that if the Accounting Expert requests a hearing before making a determination, such hearing shall be held within twenty (20) Business Days of the Parties’ delivery of their respective calculation notices and the determination of each of the disputed Final Closing Amounts shall be made within ten (10) Business Days after such hearing. The Accounting Expert’s determination of the disputed Final Closing Amounts shall be final and binding on each of the Parties hereto; provided that in no event shall Final Closing Equity Book Value be less than Purchaser’s calculation of Proposed Final Closing Equity Book Value delivered pursuant to Section 2.5(a), or more than the Seller Parents’ calculation of Final Closing Equity Book Value in the Notice of Objection delivered pursuant to Section 2.5(b) (absent manifest error). The fees and expenses of the Accounting Expert shall be paid by the Purchaser, on the one hand, and the Seller Parents, on the other, based on the percentage that the portion of the disputed amount not awarded to the Purchaser, on the one hand, and the Seller Parents, on the other, bears to the amount actually disputed by such Person(s). Each Party shall bear the costs of its own counsel, witnesses (if any) and employees.

(d) If the Final Purchase Price exceeds the Estimated Purchase Price, the Purchaser shall pay, within two (2) Business Days of the determination of the Final Closing Amount, an amount equal to the excess of the Final Purchase Price over the Estimated Purchase Price by wire transfer in immediately available funds to an account or accounts specified by the Seller; provided that, if (x) Legal Requirements prohibited or limited the ability of the Company to dividend or distribute Cash to the extent required by the second sentence of Section 7.12 and, as a result, the Estimated Closing Equity Book Value exceeded the Base Equity Book Value and (y) the Final Closing Equity Book Value exceeds the Base Equity Book Value, the Purchaser instead shall pay, within two (2) Business Days of the determination of the Final Closing Amounts, an amount equal to the excess of the Final Purchase Price over the Base Purchase Price, by wire transfer in immediately available funds to an account or accounts specified by the Seller. If the Final Purchase Price is less than the Estimated Purchase Price, the Seller shall (and Seller Parents shall cause the Seller to) pay, within two (2) Business Days of the determination of the Final Closing Amounts, an amount equal to such deficit to the Purchaser by wire transfer in immediately available funds to an account or accounts specified by the Purchaser. Any payment in respect of the Final Purchase Price made under this Section 2.5(d) shall be made by way of an adjustment to the Purchase Price, and the Purchase Price shall be deemed to have been reduced or increased, as the case may be, by the amount of such payment and such adjustment shall be allocated in accordance with Section 10.3.

Notwithstanding anything in this Section 7.2, subject to Section 10.3, the Seller Parties shall not be required (a) to permit access to or furnish Tax Returns, books, records, contracts, documents, information or data relating to Taxes that do

not exclusively relate to the Company, or (b) to provide information or reports that are not produced in the Ordinary Course of Business of the Company (including in a form other than in the form produced in the Ordinary Course of Business of the Company).

(b) Without limiting the foregoing, beginning as soon as reasonably practicable after the date hereof and continuing until the Closing Date, subject to Legal Requirements and the Non-Disclosure Agreement, the Seller Parties shall cause the Company to provide the Purchaser with the reports described in Schedule 7.2(b) of the Seller Disclosure Letter.

Section 7.3. Filings; Reasonable Best Efforts to Close. (a) The Seller Parties and the Purchaser shall (and shall cause their respective Subsidiaries to), as soon as reasonably practicable and, in the case of Mandatory Governmental Approvals, in no event more than fifteen (15) Business Days following the date hereof, prepare and file with each applicable Governmental Body requests for, or notices with respect to, such Governmental Authorizations as may be necessary for the consummation of the transactions contemplated hereby and by the Related Agreements in accordance with the terms of this Agreement and the Related Agreements, including all Mandatory Governmental Approvals and any additional Governmental Authorizations deemed advisable by Purchaser and the Seller Parties. The Seller Parties and the Purchaser shall (and shall cause their respective Subsidiaries to) diligently pursue and use their reasonable best efforts to obtain such Governmental Authorizations and will cooperate with each other in seeking such Governmental Authorizations. Until the Closing Date, the Seller Parties and the Purchaser shall (and shall cause their respective Subsidiaries to), as promptly as practicable, (i) provide such information and communications to any such Governmental Body or other Persons as such Governmental Body or other Persons may reasonably request in connection with the activities listed in this Section 7.3(a); and (ii) provide reasonable cooperation to the other Parties in connection with the performance of their obligations under this Section 7.3(a). The Parties will promptly notify each other when any such Governmental Authorizations or related filing or notice referred to in this Section 7.3(a) is obtained, taken, made, or given, as applicable, will keep each other reasonably and promptly informed as to the progress of any such actions and will promptly advise each other of any communications (and, unless precluded by any Legal Requirement, promptly provide copies of any such communications that are in writing) with any Governmental Body or other Person regarding any of the transactions contemplated by this Agreement or any of the Related Agreements.

(b) (i) Upon the terms and subject to the conditions set forth in this Agreement, each of the Parties shall, and shall cause their respective Subsidiaries to, use their reasonable best efforts to consummate the transactions contemplated by this Agreement.

(ii) In connection with obtaining any Mandatory Government Approval, nothing in this Agreement shall be deemed to require the Purchaser and its Subsidiaries to, and the Seller Parties shall not agree without the Purchaser’s consent to, sell, divest or otherwise dispose of Equity Interests or of any business,

assets or property, or the imposition of any limitation on the ability of any of them to conduct their respective businesses or to own or exercise control of such Equity Interests, businesses, assets or properties if such actions reasonably would be expected to have a material adverse effect on (A) the Business, taken as a whole or (B) the operations of the business of the Purchaser and its Affiliates, taken as a whole (any such sale, divestiture, disposition, or limitation, a “Burdensome Condition”). In the event that the Company is required as a condition to the receipt of any Mandatory Governmental Approval to divest any business, assets or property, the net proceeds of such divestiture shall be placed on deposit in a segregated account of the Company and transferred to the Purchaser at the Closing.

Section 7.4. Employees and Employee Benefits; Continuing Employees. (a) The Continuing Employees shall continue to be employed by the Company as of, and immediately after, the Closing Date in accordance with the terms set forth in this Section 7.4.

(b) Compensation and Benefits. The Purchaser will, or will cause the Company to, provide each Continuing Employee with:

(i) during the period beginning immediately following the Closing Date and ending twelve (12) months thereafter (the “Continuation Period”), a base wage rate or salary that is, for each Continuing Employee, at least as favorable as was provided to such employee immediately prior to the Closing Date;

(ii) (A) for 2010, the Purchaser will retain the Company’s existing bonus program; and (B) for 2011, the Purchaser will offer a bonus program similar to the Company’s existing bonus program (the “2011 Bonus Plan”) but, for the avoidance of doubt, with awards made at the discretion of the Company (but including a “target” annual bonus pool commensurate with the target annual bonus pool established for Business Employees under the 2010 Bonus Plan) and consistent with the Purchaser’s bonus policies and practices. Notwithstanding the foregoing, in the event the Closing has not occurred by December 1, 2010 and it is readily apparent that the Closing will not occur on or prior to January 1, 2011 (a “Delayed Closing Event”), the Seller Parties may establish and communicate the terms of the 2011 Bonus Plan to employees of the Company, on terms materially consistent (including performance conditions) with those applicable to employees of the Company under the 2010 Bonus Plan (including a “target” annual bonus pool commensurate with the target annual bonus pool established for Business Employees under the 2010 Bonus Plan) and Schedule 7.4(b)(ii). In such event the Seller Parties will consult with Purchaser regarding any applicable deferral terms applicable to bonus payments under the 2011 Bonus Plan; provided that such deferral terms, if any, shall be no less favorable to the Company employees than was applicable under the 2010 Bonus Plan;

(iii) during the Continuation Period, eligibility to participate in employee benefit plans, programs, policies and similar arrangements (whether or not subject to ERISA) that are substantially comparable in the aggregate to those

employee benefit plans, programs, policies and similar arrangements provided to such employee immediately prior to the Closing Date (any such employee health and welfare benefit plans of the Purchaser, the Company or their Subsidiaries in which Continuing Employees become eligible to participate after the Closing Date shall be referred to hereinafter as “Purchaser Welfare Plans”); and

(iv) during the Continuation Period, severance payments to each eligible Continuing Employee in accordance with the terms set forth regarding severance on Schedule 7.4(b)(iv).

(i) Except as provided in Section 7.4(f), as of the Closing Date, the Purchaser and the Company shall have sole responsibility and liability, and the Seller shall have no responsibility or liability, in respect of Business Employees for claims incurred and benefits or compensation earned, or to be earned (whether related to periods before, on or after the Closing Date) under any Employee Plan with respect to the Company (including any severance or other termination benefits which become payable to any Business Employees as a result of or following the transactions contemplated by this Agreement), any claims or causes of action under Legal Requirements with respect to employment, wages and all other compensation and working condition matters with the Company and, for the avoidance of doubt, any liability (including severance or other termination benefits or claims for such benefits) arising out of the Purchaser’s or the Company’s termination of employment of any Business Employee on or after the Closing Date (a “Purchaser Termination”); provided, that (x) any such liability under Seller Plans (other than medical and dental claims which are governed by clause (iii) below) shall be limited to those that otherwise would have been charged to the Company in accordance with past practice, (y) Seller Parties shall notify Purchaser within thirty (30) days of learning of any such potential liability and (z) the Purchaser shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the applicable judicial authority in respect of such claim and may, at its sole option, contest the claim in any permissible manner.

Without limiting the foregoing, and for the avoidance of doubt, the Purchaser or the Company, shall assume and honor in accordance with its terms, with respect to Business Employee, any bonus plan, agreement or arrangement and any applicable employment letter or offer letter applicable to such Business Employee, to the extent set forth on Schedule 3.5(a) or Schedule 3.5(j); provided, nothing contained herein shall prevent any amendment of the foregoing arrangements by the Purchaser or the Company to the extent such arrangements may be amended in accordance with their terms.

(ii) As of the Closing Date, the Company shall cease to be a participating employer under each Seller Plan. The Seller Parties shall or shall

cause the Company or their Subsidiaries to notify Business Employees that, except as provided in Section 7.4(f) or as set forth on Schedule 7.4(c)(ii), as of the Closing Date, Business Employees shall cease to accrue any further benefits as active participants and shall have no rights to continue as active participants under the Seller Plans (without derogation of their rights as vested, terminated participants). With respect to any premiums, claims or benefits or related costs relating to Business Employees in respect of the Seller Plans which are medical or dental plans which are known to the Seller Parties to be outstanding and unsatisfied as of immediately prior to the Closing and that otherwise would have been charged directly or indirectly to the Company or its Subsidiaries in accordance with past practice (“Known Outstanding Medical Claims”), the Seller Parties shall either (i) cause the Company to pay the aggregate amount of such Known Outstanding Medical Claims to the Seller Parties prior to the Closing or (ii) forgive, and discharge the Company and its Subsidiaries from, the aggregate amount of such Known Outstanding Medical Claims (the “Pre-Closing Medical Claim Action”). Any responsibility or liability retained or assumed by the Purchaser, its Subsidiaries and the Company in respect of the Seller Plans which are medical or dental plans shall be limited to reimbursement to the Seller Parties in respect of premiums, claims or benefits and related costs that are unpaid, and unforgiven, as of the Closing Date (after giving effect to the Pre-Closing Medical Claim Action) and that otherwise would have been charged directly or indirectly to the Company or its Subsidiaries in accordance with past practice.

(iii) With respect to medical benefits provided pursuant to Seller Plans, for a Business Employee, the Seller Parties shall retain all Liability for all medical or dental claims incurred before, or incurred pursuant to a course of treatment initiated prior to, the Closing Date, and the Purchaser and its Affiliates (including, following the Closing Date, the Company) shall have no such Liability, except that the Purchaser shall, or shall cause the Company to, reimburse the Seller Parties in respect of premiums, claims or benefits and related costs that are unpaid, and unforgiven, as of the Closing Date (after giving effect to the Pre-Closing Medical Claim Action) and that otherwise would have been charged directly or indirectly to the Company or its Subsidiaries in accordance with past practice.

(iv) The Purchaser shall, or shall cause the Company to, cause any employee benefit plans in which the Continuing Employees are eligible to participate on or after the Closing Date, to take into account for purposes of eligibility, vesting and benefit accrual thereunder (including without limitation, under any severance plan or program, but excluding benefit accrual under any defined benefit pension plan that a Continuing Employee becomes eligible to participate in on or after the Closing Date, for purposes of qualifying for subsidized retirement benefits or to the extent it would result in a duplication of benefits), service by such Continuing Employees with the Seller Parties or any of their Subsidiaries or with the Company as if such service were with the Purchaser,

to the same extent such service was credited under a comparable Employee Plan as of the Closing Date.

(d) Welfare Benefits. With respect to the Purchaser Welfare Plans, except to the extent otherwise prohibited under Legal Requirements, the Purchaser shall, or shall cause the Company to, use commercially reasonable efforts to:

(i) with respect to each such plan that is a medical, dental or health plan, to waive, or cause the waiver of, any exclusions for pre-existing conditions (assuming HIPAA creditable coverage) and waiting periods for each Continuing Employee, from and after the Closing Date and his/her dependents to the extent that such pre-existing condition exclusions and waiting periods were previously satisfied under the comparable Employee Plan in which the Continuing Employee participated or was eligible to participate prior to the Closing Date for the plan year that includes such transfer; and

(ii) with respect to each such plan that is a medical, dental or health plan, to provide each Continuing Employee, from and after the Closing Date, upon presentation of evidence satisfactory to such plans, with credit for any deductibles and out-of-pocket expenses paid or incurred by such Continuing Employee (and any enrolled dependents) for the current plan year under the applicable Employee Plan, prior to such Continuing Employee’s transfer to the Purchaser Welfare Plan (to the same extent such credit was given under the comparable Employee Plan) in satisfying any applicable deductible or out-of-pocket requirements under such Purchaser Welfare Plan for the plan year that includes such transfer; provided that, for the avoidance of doubt, the foregoing shall not require the Purchaser to reimburse any Continuing Employee who has exceeded the limits under the Purchaser Welfare Plan.

(e) Vacation and Sick Leave. The Purchaser shall, or shall cause the Company to, honor each Continuing Employee’s unused vacation, paid time off and sick leave accrued as of the Closing Date under the relevant Employee Plan consistent with the Company’s past practice as described on Schedule 7.4(e).

(f) Continuation of Health Care. The Purchaser shall, or shall cause the Company to, be responsible for all legally mandated continuation of health care coverage for all Business Employees and any of their covered dependents who experience a qualifying event on or prior to the Closing Date, provided that with respect to any such legally mandated continuation of health coverage that is provided under a Seller Plan on or prior to the Closing Date, the liabilities and responsibilities of the Purchaser and the Company shall be limited to reimbursing the Seller Parties in respect of premiums, claims or benefits and related costs that otherwise would have been charged directly or indirectly to the applicable employer in accordance with past practice. The Purchaser and the Company shall be responsible for all legally mandated continuation of healthcare coverage for all Business Employees and any of their covered dependents who experience a qualifying event occurring following the Closing Date.

(g) Assumption of Obligations.

(i) Subject to Legal Requirements and for the avoidance of doubt, the Purchaser shall, or shall cause the Company to (x) assume the obligation to pay, and shall, or shall cause the Company to, pay to the Business Employees, the amounts specified in Schedule 3.5(j) applicable to each such Business Employee, in accordance with the terms set forth in the applicable plan, program or arrangement in which such Business Employees participate (the “Bonus Plans”), as such Bonus Plans may be amended from time to time, (y) continue to operate the Bonus Plan, for the 2010 and prior performance years only (and, if the Delayed Closing Event has occurred, for the 2011 performance year), with respect to such Business Employees as though references to the Seller Parties and their Affiliates, as applicable, were deemed references to the Purchaser and its Affiliates and (z) assume the obligation to pay, and to cause the Company to pay, amounts (if any) that may become payable as specified in Schedule 7.4(g).

(ii) From time to time after the Closing (but no more than once every six (6) months), the Seller Parties may request that the Purchaser inform, and upon receipt of each such request the Purchaser shall inform (or shall cause the Company to inform) the Seller Parties of the cessation of employment of any Business Employee who, as of the Closing Date, was a participant in the Bonus Plan for the 2010 performance year and prior performance years (and, if the Delayed Closing Event has occurred, for the 2011 performance year) and who, upon such cessation of employment, forfeited the right to payment of any amount under such Bonus Plans (which for 2010 or, if the Closing occurs in 2011, which for 2011 was attributable to the period before the Closing Date) and, if so, the amount thereof (a “Forfeited Bonus”). In the event the Purchaser (or the Company) notifies the Seller Parties of any Forfeited Bonus, the Purchaser shall, or shall cause the Company to, promptly , and in any event within ten (10) Business Days thereafter, reimburse the Seller Parties the amount of such Forfeited Bonus, provided that the maximum aggregate amount required to be paid by the Purchaser to the Seller Parties on account of all Forfeited Bonuses shall not exceed the sum of the amounts under clauses (a), (b) and (c) of the definition of “Closing Adjustment Amount.”

(h) Retirement Plans. With respect to the Sempra Energy Trading LLC Retirement Savings Plan and any other 401(k) plan in which the Continuing Employees participate (all such plans, the “Seller 401(k) Plan”), on or prior to the Closing Date, the Seller Parties shall cause all Continuing Employees participating in such plans to be fully vested in their respective accounts thereunder. In the event that a Continuing Employee makes a voluntary election pursuant to Section 401(a)(31) of the Code to rollover such Continuing Employee’s account balance in the Seller 401(k) Plan to a tax-qualified defined contribution plan sponsored by the Purchaser or any of its Subsidiaries, the Purchaser agrees to cause such tax-qualified defined contribution plan to accept such rollover to the extent permitted by Legal Requirement. The Seller Parties shall use commercially reasonable efforts to cooperate with the Purchaser to effect the rollover of such account balances.

(i) Location of Employment. The Purchaser agrees that the Continuing Employees shall be employed by the Company or the Purchaser (or one its Affiliates) immediately after the Closing at their present locations of employment with the Company, except as set forth in Schedule 7.4(i), and the Purchaser shall not condition (and shall not permit the Company to condition) the employment of any Continuing Employee immediately after the Closing and during the Continuation Period on such Continuing Employee agreeing to relocate to another location.

(j) No Third Party Beneficiary Rights. Nothing contained herein, whether express or implied shall be treated as an amendment or other modification of any employee benefit plan, program, arrangement or agreement. This Section 7.4 shall inure exclusively to the benefit of, and be binding solely upon, the Parties to this Agreement and their respective successors, permitted assigns, executors and legal representatives. Nothing in this Section 7.4, expressed or implied, shall be construed to create any third-party beneficiary rights in any present or former employee, service provider or any such Person’s alternate payees, dependents or beneficiaries, whether in respect of continued employment or resumed employment, compensation, employee benefits or otherwise. Nothing herein shall prevent the Purchaser or the Company from entering into an agreement with a Business Employee, inconsistent with any obligation to the Seller Parties hereunder, to make a payment or provide any employee any benefit hereunder; provided that the Seller Parties shall have no Liability with respect thereto, or as a result thereof (any such Liabilities being expressly assumed by, and retained by, the Purchaser and the Company). Nothing herein shall prevent Purchaser or the Company from amending or terminating any plan or agreement in accordance with its terms or shall guarantee any Continuing Employee’s employment for a specified period or in any particular location.

Section 7.5. Retention of and Access to Records; Confidentiality. (a) As from and after the date hereof until the fourth (4th) anniversary of the Closing, each of the Seller Parties shall (and shall cause their respective Subsidiaries to) treat as confidential and shall safeguard any and all information, knowledge and data to the extent related to the Company or the Business (other than historical financial reporting information presented on a consolidated basis with other historical financial reporting information of the Seller Parents) (the “Business Confidential Information”), in each case, in their respective possession by using the same degree of care, but no less than a reasonable standard of care, to prevent the unauthorized use, dissemination or disclosure of such information, knowledge and data as such Seller Party used with respect thereto prior to the date hereof. The Parties agree that any Seller Party may only disclose such information (A) to the extent counsel to such Seller Party advises that disclosure is required to comply with Legal Requirements (provided that such Seller Party shall provide prior written notice to the Purchaser of such disclosure (unless prohibited by any Legal Requirement) as promptly as practical under the circumstances and shall seek other than with respect to securities laws or stock exchange rules to limit any such disclosure and to protect from public disclosure by way of protective order or otherwise, in each case, to the extent permitted by Legal Requirements), and (B) to its directors, officers, employees, agents and professional advisers who reasonably need to know such information for purposes of this Agreement or any Related Agreement or any other purposes expressly contemplated hereby or thereby (provided that such Seller Party shall instruct any such director, officer, employee, agent or professional to keep such

information confidential in accordance with this Agreement). In no event shall any Seller Party use, or permit any other Person to use, the Business Confidential Information for any purpose other than as expressly contemplated under this Agreement or any Related Agreement.

(b) From and after the date hereof until the fourth (4th) anniversary of the Closing, the Purchaser shall (and shall cause its Subsidiaries, including the Company, to) treat as confidential and shall safeguard any and all information, knowledge and data relating to the businesses of the Seller Parties and their respective Affiliates that is not Business Confidential Information (the “Seller Confidential Information”), in each case, that has become known or becomes known to the Purchaser as a result of the transactions contemplated by this Agreement by using the same degree of care, but no less than a reasonable standard of care, to prevent the unauthorized use, dissemination or disclosure of such information, knowledge and data as the Purchaser uses with respect to its own information, knowledge and data. The Parties agree that the Purchaser may disclose such information (A) to the extent counsel to the Purchaser advises that disclosure is required to comply with Legal Requirements (provided that the Purchaser shall provide prior written notice to the Seller Parties of such disclosure (unless prohibited by any Legal Requirement) as promptly as practical under the circumstances and shall seek (other than with respect to securities laws or stock exchange rules) to limit any such disclosure and to protect from public disclosure by way of protective order or otherwise, in each case, to the extent permitted by Legal Requirements), and (B) to its directors, officers, employees, agents and professional advisers who reasonably need to know such information for purposes of this Agreement or any Related Agreement or any other purposes expressly contemplated hereby or thereby (provided that the Purchaser shall instruct any such director, officer, employee, agent or professional to keep such information confidential in accordance with this Agreement). In no event shall Purchaser use, or permit any other Person to use, the Seller Confidential Information for any purpose other than as expressly contemplated under this Agreement or any Related Agreement.

(c) The Parties acknowledge that the confidentiality obligations set forth in this Section 7.5 shall not extend to information, knowledge and data that (i) is or becomes publicly available through no act or omission of a Party owing a confidentiality obligation imposed by this Section 7.5 in respect of such information, knowledge and data (a “Receiving Party”), (ii) is or becomes available to a Receiving Party on a non-confidential basis from a source other than the Party to which such information, knowledge and data relates; provided that the source of such information, knowledge and data was not known to the Receiving Party to be bound by confidentiality obligations to the Party to which such information, knowledge and data relates, or (iii) the Receiving Party can establish that it independently developed such information, knowledge and data without reference to information, knowledge and data provided to such Receiving Party in connection with the transactions contemplated hereby.

(d) The Parties acknowledge that the Non-Disclosure Agreement remains in full force and effect and, from and after the date hereof, the Purchaser agrees to comply with the Non-Disclosure Agreement as if it were a party thereto as the addressee thereof; provided that after the Closing Date, (i) Purchaser’s confidentiality obligations thereunder shall terminate and be of no further force or effect only as to the Business Confidential Information,

and (ii) the restrictions on solicitation and hiring thereunder shall terminate and be of no further force or effect only as to Business Employees.

(e) From the Closing Date until the seventh (7th) anniversary thereof, the Purchaser shall (and shall cause its Subsidiaries, including the Company, to) provide the Seller Parties and their respective Subsidiaries and their Representatives reasonable access to inspect and copy the Business Confidential Information in respect of matters relating to or affected by operations of the Business prior to the Closing Date, during normal business hours and on reasonable notice, for any reasonable business purpose, or to enable them to prepare financial statements or tax returns, respond to tax audits or as they may otherwise reasonably request, except to the extent that furnishing any such information or data would violate any Legal Requirement or Order. From the Closing Date until such time as all obligations of the Seller Parties and their Affiliates under the Seller Financial Assurances have been fully and unconditionally released or otherwise terminated with no possibility of further liabilities on the part of the Seller Parties or their Affiliates, the Purchaser shall (and shall cause its Subsidiaries, including the Company, to) provide the Seller Parents and their Representatives reasonable access to such information, including the relevant portions of the underlying Contracts (other than books and records relating to Taxes, access to which is governed exclusively by Section 10.3): (i) as is reasonably necessary for any Seller Parent (x) to determine its and its Affiliate’s potential exposure under its outstanding Seller Financial Assurances and whether any Third Party Claim in respect of a Seller Financial Assurance is proper and (y) to monitor and enforce the provisions of Section 7.18 and the applicable Financial Assurances Reimbursement and Indemnity Agreement and the applicable Collateral Security Agreement, (ii) to permit such Seller Parent or its Affiliate to enforce any rights it may have under, or defend any claim under, any Seller Financial Assurance, (iii) for regulatory purposes or (iv) to enable them to prepare financial statements. Any such access shall be during normal business hours and on reasonable notice and subject to Legal Requirements.

(f) From the Closing Date until the seventh (7th) anniversary thereof, the Seller Parties shall (and shall cause their respective Subsidiaries to) retain any material books and records relating to the Business not delivered to the Purchaser at the Closing, and shall provide the Purchaser, the Company, their respective Subsidiaries and their Representatives reasonable access to inspect and copy such books and records in connection with matters relating to or affected by operations of the Business prior to the Closing Date (other than books and records relating to Taxes, access to which is governed exclusively by Section 10.3), during normal business hours and on reasonable notice, for any reasonable business purpose, including to enable them to prepare financial statements or tax returns, respond to tax audits or as they may otherwise reasonably request, except to the extent that furnishing any such books or records would violate any Legal Requirement or Order.

Section 7.6. Restrictive Covenants.

Subsequent to any acquisition of any Person or business by any Seller Parent or any of its Restricted Subsidiaries permitted by clause (i) above, during the Non-Compete Period such Person’s or business’s annual gross revenue margin from the Restricted Business shall not exceed the lower of (x) 15% of such Person’s or business’s total annual consolidated gross revenue margin or (y) $90,000,000 (based, in each case, on the most recent full fiscal year audited consolidated income statement of such Person or business);

than if such termination was in connection with a violation of this Section 7.6), or (ii) making general advertisements for employment and hiring any individual who responds to such general advertisements.

(e) Each Seller Parent acknowledges that the restrictions contained in this Section 7.6 are reasonable and necessary to protect the legitimate interests of the Purchaser and constitute a material inducement to the Purchaser to enter into this Agreement and consummate the transactions contemplated hereby. Each Seller Parent acknowledges that any violation of this Section 7.6 will result in irreparable injury to the Purchaser and agrees that the Purchaser shall be entitled to preliminary and permanent injunctive relief, without the necessity of proving actual damages, as well as an equitable accounting of all earnings, profits and other benefits arising from any violation of this Section 7.6, which rights shall be cumulative and in addition to any other rights or remedies to which the Purchaser may be entitled.

(f) In the event that any covenant contained in this Section 7.6 is adjudicated to exceed the time, geographic, product or service, or other limitations permitted by applicable Legal Requirement in any jurisdiction, then any court is expressly empowered to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, product or service, or other limitations permitted by applicable Legal Requirement. For the sake of clarity, in no event shall any reformation pursuant to this Section impose burdens or restrictions of any nature in excess of those set forth herein upon any Seller Parent or any Restricted Subsidiary. The covenants contained in this Section 7.6 and each provision thereof are severable and distinct covenants and provisions.

Section 7.11. Use of Certain Intellectual Property. (a) The Purchaser agrees that the Purchaser and the Company will have no right, title, or interest in or right to use any Trademarks listed on Schedule 7.11 hereto and any Trademark that comprises or includes such Trademarks or is confusingly similar thereto (collectively, the “Seller Parent Marks”), except that such restrictions shall not apply to the use of “energy”, “solutions” or “energy trading.” The Parties acknowledge that certain of the materials and assets of the Company (including, but not limited to, signage, stationery and promotional materials) currently bear the Seller Parent Marks. Within one hundred twenty (120) days after the Closing Date, the Purchaser shall, and shall cause the Company to: (i) cease all use of the Seller Parent Marks; (ii) take all necessary actions to either remove, conceal, cover, redact and/or replace all Seller Parent Marks from such materials and assets or destroy such materials and assets in the possession or control of the Purchaser or the Company; and (iii) make all necessary filings and use commercially reasonable efforts to cause all applicable Governmental Bodies to change all applications, registrations and filings, including, but not limited to, corporate names, seals and certificates, such that they will not include any Seller Parent Marks.

properly notified or registered with the FSA and in accordance with Legal Requirements for the period permitted by this Section 7.11(a).

(d) After the Closing Date, the Seller Parties shall not, and shall cause each of their respective Affiliates not to, exploit or make use of, or authorize any Third Party to exploit or make use of, any of the Company Intellectual Property, except as permitted under this Agreement or by any Related Agreement. After the Closing Date, nothing in this Agreement shall give the Purchaser or the Company or any of their respective Affiliates the right to exploit or make use of, or authorize any Third Party to exploit or make use of, any Intellectual Property owned by the Seller Parties or their Subsidiaries (other than the Company), except with respect to the trademark license under this Agreement or except as provided in any Related Agreement.

(e) The Seller Parties on behalf of themselves and their respective current Affiliates and effective as of the Closing, hereby covenant not to ▇▇▇ or initiate any Proceeding, either alone or in cooperation with any other Person, whether for direct or contributory infringement, violation or misappropriation, or inducement of infringement, violation or misappropriation, against the Purchaser or the Company or any of their customers (mediate or immediate), developers, manufacturers and resellers (and all employees of the foregoing), in each case that have such relationship with the Company as of the Closing Date, under any Intellectual Property rights owned by the Seller Parties as of the Closing Date, other than the Seller Parent Marks (“Seller IP”) to the extent that such Seller IP is used in or has been used or embodied in any of the products or services provided by the Company’s Business as of the Closing Date, including the Company Software to the extent that the Company Software has been created or developed by the Seller Parties as of Closing.

the Base Equity Book Value (as determined in good faith by the Seller Parties). It is understood and agreed that, subject to Legal Requirements, immediately prior to the Closing the Seller Parents shall cause the Company to pay dividends and make distributions of Cash to the extent required (as determined in good faith by the Seller Parties) to cause the Estimated Closing Equity Book Value (disregarding the exception in clause (i) of the definition of “Estimated Closing Balance Sheet” when determining the Estimated Closing Equity Book Value) to equal the Base Equity Book Value. The Seller Parties shall not be liable for any inaccuracy or error made in determining the amount of such dividend or distribution, provided that such amounts are determined in good faith and provided further, that the Seller Parties comply with Section 2.5(d).

(a) In the event and for so long as any Party actively is contesting or defending any Proceeding by a Third Party (and to which none of the other Parties is a party having an interest adverse to that of such Party) in connection with any transaction contemplated under this Agreement or any Related Agreements at the reasonable request of such Party to any other Party, the requested Party shall, and shall cause its Subsidiaries and controlled Affiliates to, cooperate reasonably with the requesting Party and its counsel in the contest or defense of such Third-Party Claim, reasonably cooperate with requests to make available its personnel and provide reasonable access to its books and records during normal business hours (subject to appropriate confidentiality protections) as shall be reasonably necessary in connection with such contest or defense. For the avoidance of doubt, the

cooperation of the Parties in respect of any Third-Party Claim is subject in all respects to the procedures in Section 9.5(b) rather than this Section 7.14(a).

(b) At the reasonable request of any Party, the other Party shall, and shall cause its Subsidiaries and controlled Affiliates to, cooperate reasonably with the requesting Party and its accountants in (i) the preparation of any financial statements or tax returns and (ii) the response to or conduct of any tax audit or other audit (including by making available its personnel and providing testimony and reasonable access to its books and records during normal business hours, subject to appropriate confidentiality protections, as may be reasonably requested by such Party in connection therewith).

Upon payment of such amounts, each of RBS and the Seller shall acknowledge (in writing, in a form reasonably satisfactory to the Purchaser) on behalf of itself and each relevant Subsidiary the repayment and discharge of (including the release of all Encumbrances relating to) the relevant portions of the Estimated Closing RBS Debt. All payments pursuant to this Section 7.15(a) in respect of the RBS Debt shall be subject to adjustment pursuant to Section 7.15(b).

(b) If the Final Closing RBS Debt exceeds the Estimated Closing RBS Debt, the Purchaser shall pay (on behalf of the Company), within two (2) Business Days of determination of the Final Closing RBS Debt, (i) to RBS (on behalf of RBS and its Subsidiaries) an amount equal to the portion of such excess attributable to the RBS Debt that is owed to RBS or any of its Subsidiaries (other than the Seller and the Seller Companies) by wire transfer in immediately available funds to such account(s) as may be specified by RBS and (ii) to the Seller (on account of the Seller and its Subsidiaries) an amount equal to the portion of such excess attributable to the RBS Debt that is owed to the Seller or any Seller Company (other than the Company) by wire transfer in immediately available funds to such account(s) as may be specified by the Seller. If the Final Closing RBS Debt is less than the Estimated Closing RBS Debt, (i) RBS (on behalf of itself and each relevant Subsidiary) shall repay, within two (2) Business Days of the determination of the Final Closing RBS Debt, an

amount equal to the portion of such deficit attributable to the RBS Debt that is owed by RBS or any of its Subsidiaries (other than the Seller and the Seller Companies) by wire transfer in immediately available funds to an account or accounts specified by the Purchaser and (ii) the Seller (on behalf of itself and the Seller Companies) shall (and Seller Parents shall cause the Seller to) repay, within two (2) Business Days of the determination of the Final Closing RBS Debt, an amount equal to the portion of such deficit attributable to the RBS Debt that is owed by the Seller or any Seller Company by wire transfer in immediately available funds to an account or accounts specified by the Purchaser. If the Final Closing RBS Debt is greater than the Estimated Closing RBS Debt but either the portion of the RBS Debt owed to RBS or any of its Subsidiaries (other than the Seller or any of the Seller Companies) is less than the estimated amount of the same or the portion of the RBS Debt owed to the Seller or any of the Seller Companies is less than the estimated amount of the same, then RBS or the Seller, as applicable, shall pay over to the other the amount by which its portion of the RBS Debt was less than the estimated amount of the same.

In particular, it is understood that Financial Assurance Beneficiaries who do not have a commercial relationship with the Purchaser may require additional information, including financial information of the Purchaser for the 2010 fiscal year, in connection with the Credit Support Replacement Actions or any Credit Support Releases. It shall not be considered a default or breach of Purchaser’s obligations under this Section 7.18 if Purchaser is unable to procure that all of the Credit Support Replacement Actions or Credit Support Releases occur, so long as Purchaser has used its reasonable best efforts as required by Section 7.18(a).

(c) From and after the Closing Date, the Purchaser shall post and maintain for the benefit of the relevant Seller Party or Affiliate thereof (unless at such time the relevant Seller Party or such Affiliate does not and could not have any liability or obligation under any Seller Financial Assurance), the type and amount of collateral required to be posted to and maintained with such Seller Party or such Affiliate under the applicable Collateral Security Agreements. From and after the Closing Date, the Seller Parties and their Affiliates will not issue or make any new Seller Financial Assurance.

(d) During the Credit Transition Period, the Sellers Parties shall not (and shall cause their Subsidiaries not to) terminate any Seller Financial Assurance outstanding on the Closing Date in whole or in part (other than a partial termination of a Shared Trading Guarantee with respect to the portion of such Shared Trading Guarantee issued solely in connection with obligations other than obligations of the Company) without the prior written consent of the Purchaser, it being understood that during the Credit Transition Period the Company shall be permitted to enter into new Commodity Transactions that are supported by any Seller Financial Assurance outstanding on the Closing Date in accordance with the provisions of this Section 7.18 and subject to the limitations set forth in Schedule 7.18(d). At

any time following the expiration of the Credit Transition Period, the relevant Seller Party or Affiliate thereof may send notice of termination of any of its Seller Financial Assurances; provided that in no event shall the termination of any Seller Financial Assurance be effective with respect to any transactions covered thereby that were entered into prior to the effective date of such termination; provided, further, that such transaction existed at the Closing or arose under a transaction entered into in accordance with the provisions of this Section 7.18, including the limitations set forth in Schedule 7.18(d).

(e) At or prior to the Closing, the Purchaser will enter into the Financial Assurance Reimbursement and Indemnity Agreements and the Collateral Security Agreements.

(f) Immediately prior to the Closing, the Purchaser and the Seller Parties will take the actions set forth in Schedule 7.18(f) with respect to the DBS Letter of Credit.

(g) Subject in all cases to Legal Requirements (including, for the avoidance of doubt, Legal Requirements regulating the sharing of information by banking institutions) and the Non-Disclosure Agreement, following the date hereof and prior to the Closing:

(i) the Purchaser shall have the right to contact and have discussions with each Financial Assurance Beneficiary, in each case to the extent reasonably necessary to satisfy its obligations under this Section 7.18; provided that the initial contacts with any such Financial Assurance Beneficiary shall be coordinated in advance between the Purchaser and the Seller Parties and thereafter, Purchaser shall use reasonable efforts to copy the Seller Parties on any such contact by writing and to give the relevant Seller Parties reasonable prior notice of any discussion or meeting with a Financial Assurance Beneficiary that is initiated by Purchaser prior thereto, and upon its reasonable request any Seller Party shall be permitted to participate in any such discussion or meeting with any such Financial Assurance Beneficiary; and

(ii) to the extent reasonably requested of the Seller Parties in writing by the Purchaser, the Seller Parties agree to, and to cause the Company to, at the Purchaser’s sole expense, cooperate in good faith in connection with a Purchaser “road show” for the purpose of introducing the Purchaser to counterparties to the Company Trading Agreements and facilitating the Credit Support Replacement Actions, Credit Support Releases and related activities described in Section 7.18(a); provided that such requested cooperation does not unreasonably interfere with the ongoing operations of the Seller Parties and their respective Subsidiaries, including the Company. The Purchaser shall, promptly upon request by any Seller Party, reimburse such Seller Party for all reasonable, documented out-of-pocket costs incurred and paid by such Seller Party or any of its Affiliates in connection with such cooperation.

(h) Notwithstanding anything to the contrary contained herein:

(i) Purchaser and its Affiliates shall not (A) enter into any transactions after the expiration of the Credit Transition Period in the name of any Seller Party

or Affiliate thereof or that would be covered by a Seller Financial Assurance or (B) amend, modify extend or renegotiate any material term of any obligation that is covered by a Seller Financial Assurance in any manner that increases or extends the potential liability or obligation of a Seller Party or Affiliate thereof under any Seller Financial Assurance, in each case without the prior written consent of the affected Seller Party (which may be given or withheld in its sole discretion).

(ii) Including the limitations set forth in Section 7.1 hereunder, following the date hereof and prior to the Closing, any Seller Party or Affiliate thereof may amend any of its Seller Financial Assurances (A) representing an uncapped obligation of such Seller Party or such Affiliate or (B) under which such Seller Party or such Affiliate has had no exposure during the twelve (12) month period prior to the date hereof (such Seller Financial Assurances, the “Inactive Obligations”) to impose a limitation on the maximum potential exposure, or, with respective to Inactive Obligations, to reduce the limitation on maximum potential exposure, respectively, of such Seller Party or such Affiliate under such Seller Financial Assurance; provided that such amendment to impose a limitation on the maximum potential exposure would not affect the Company’s ability to continue to conduct the Business in the Ordinary Course of Business as conducted over the twelve (12) month period prior to the date hereof.

(i) Notwithstanding anything in this Agreement to the contrary, including Section 7.1, with regards to the trading agreements between the Company and Sempra Energy Trading LLC (“SET”), the Purchaser acknowledges that, from and after the date hereof (including after the Closing), the Seller Parties shall be entitled to cause SET to transition the trading relationship under such agreements from a non-margined affiliated relationship to a margined non-affiliated relationship in accordance with the following: (i) prior to the Economic Transfer by SET of any the Company Trading Agreements, the unsecured margin threshold for the Company under such Company Trading Agreements shall be not less than $20,000,000; (ii) after Economic Transfer by SET to a Third Party, the unsecured margin threshold for the Company under such Company Trading Agreements shall be not less than $12,500,000 prior to February 1, 2011 and $7,500,000 on and after February 1, 2011; (iii) at any time, any exposure under such Company Trading Agreements in excess of the applicable threshold shall be posted by the Company in cash and/or letters of credit issued by a bank or other financial institution with a long-term credit rating of “A” or better; (iv) margining shall be posted on the basis of the following one-day convention: (a) if a demand for collateral is made by 1:00 p.m. New York time, then collateral transfer will be made no later than the close of business on the next local business day, and (b) if a demand for collateral is made after 1:00 p.m. New York time, then collateral transfer will be made no later than the close of business on the second succeeding local business day; and (v) the Seller Parties and the Purchaser shall negotiate in good faith, as soon as reasonably practicable after the date hereof, all other terms and conditions of such trading agreements on market terms agreeable to the Seller Parties and the Purchaser.

Section 7.19. Transfer and License to Company of Certain Assets. (a) On or prior to the Closing Date, the Seller Parties shall, and shall cause their respective Affiliates, as applicable, to, (i) transfer, assign and contribute to the Company their respective right, title and interest in, to and under each of the assets set forth on Schedule 7.19(i) (“Transferred Assets”) pursuant to one or more instruments of transfer and conveyance and (ii) grant an irrevocable, royalty-free license to the Company in respect of each of the rights set forth on Schedule 7.19(ii) (“Licensed Assets”) pursuant to one or more license agreements, in each case, in such form(s) as are reasonably acceptable to the Purchaser and the Seller Parties.

The Seller Parties shall have the right to update any of Schedule 3.16(b), Schedule 7.19(i) and Schedule 7.19(ii) to add items inadvertently omitted by delivery of such updated Schedules to the Purchaser on or prior to the Closing Date, and any such updates shall be effective for all purposes of this Agreement.

Section 7.21. Microsoft Production and Disaster Recovery Licenses.

(a) any breach of any representation or warranty made by a Seller Party in Article III of this Agreement (as made as of the date hereof and as if made as of the Closing), excluding De Minimis Damages unless the De Minimis Damages resulted from a breach of any representation or warranty made by a Seller Party in 3.2(b)(i), 3.2(b)(ii), 3.3(a), 3.8 or 3.9;

(ii) The Seller Parents shall have liability under Section 9.2(a) and 9.2(c) only if the Seller Parents receive notice of any claim from the Indemnified Person, specifying the factual basis of the claim in reasonable detail and specifying, if known, the amount claimed, (A) within the applicable survival period as defined in Section 9.1 for claims under Section 9.2(a), and (B) within thirty (30) days after the expiration of the applicable statute of limitations (giving effect to any waiver, mitigation or extension thereof), for claims under Section 9.2(c).

(i) In respect of claims for indemnification pursuant to Section 9.2(a), for a breach of a representation or warranty made solely by such Seller Parent or solely in respect of such Seller Parent, such Seller Parent shall have sole liability for the Damages attributable to such breach under the following representations and warranties: (A) with respect to Sempra Energy or RBS, such representations and warranties under Section 3.1(a), Section 3.2(a) (only with respect to the enforceability, right, power or authority as to such Seller Parent), Section 3.2(b)(i) and (ii) (only with respect to such Seller Parent’s or its Subsidiaries (other than the Seller and any of the Seller Companies (including the Company)) Governing Documents or resolutions, and Legal Requirements and Orders as applicable solely to such Seller Parent or its Subsidiaries (other than the Seller and any of the Seller Companies (including the Company)) or their properties (as opposed to and excluding the Seller or any of the Seller Companies (including the Company) (or their properties)), Section 3.9 (only with respect to such Seller Parent or its

*** Material has been omitted pursuant to a request for confidential treatment and has been filed separately.

Subsidiaries (other than the Seller and any of the Seller Companies (including the Company)) and, (B) with respect to RBS only, such representations and warranties under Section 3.5 (only with respect to any Seller Plan sponsored by RBS or its Affiliates (other than the Seller or any of the Seller Companies)), it being understood that, in each case under this Section 9.4(b)(i), any representations and warranties given in respect of the Seller, the Seller Companies (including the Company), the Business or any component thereof are deemed not to be made solely by such Seller Parent or solely in respect of such Seller Parent.

(ii) In respect of claims for indemnification pursuant to Section 9.2(b), for a breach of or failure to comply with or perform any covenants or agreements of any Seller Parent solely by such Seller Parent (it being understood that any covenants or other agreements of the Seller Parents given in respect of the Seller, the Seller Companies (including the Company), the Business or any portion thereof, are deemed not to be covenants and agreements solely of such Seller Parent), such Seller Parent shall have sole liability for the Damages attributable to such breach.

(iii) (A) Sempra Energy shall have sole liability for Sempra Tax Damages;

(B) Shared Tax Damages shall be allocated severally but not jointly between RBS on the one hand and Sempra Energy on the other hand, in accordance with the allocation of profits among the Seller Parents in their capacities as members of the Seller as set forth on Schedule 9.4(b)(iii) for the periods in which the events giving rise to such breach occurred; and

(C) Damages subject to indemnification under Section 9.2(a) as a result of a breach of the representations and warranties of the Seller set forth in Section 3.8(c) shall be allocated on the same basis as Shared Tax Damages unless the tax sharing, tax allocation, indemnity or other agreement giving rise to the breach benefited one or more (but not all) of the Seller Parties, in which case Damages shall be allocated to the Seller Party or Seller Parties who obtained such benefit, and where there is more than one such Seller Party such allocation shall be made severally but not jointly pro rata to their respective allocation of profits of the Seller during the periods in which the events giving rise to such breach occurred.

(D) Promptly, and in any event within fifteen (15) days, after the settlement or resolution of a Third-Party Claim that results in (or the receipt of notice pursuant to Section 9.6 with respect to) any Damages that are described in this Section 9.4(b)(iii), RBS and Sempra Energy shall cooperate in good faith to prepare and deliver to Purchaser an allocation statement with each of RBS's and Sempra Energy's percentage responsibilities for indemnifying for

such Damages. For the avoidance of doubt, the sum of the percentages set forth on such allocation statement shall equal 100%. In the event that RBS and Sempra Energy are unable to agree to an allocation described under this Section 9.4(b)(iii), such dispute shall be resolved by a nationally recognized expert in the relevant area with no material relationship with RBS, Sempra Energy or their Affiliates (the "Referee"), chosen and mutually acceptable to both RBS and Sempra Energy within five (5) days of the date on which the need to choose the Referee arises. The Referee shall, pursuant to such procedures as it may require, resolve such dispute within (thirty) 30 days. Promptly thereafter, RBS and Sempra Energy shall deliver to Purchaser an allocation statement reflecting the percentage responsibilities as determined by the Referee. The costs, fees and expenses of the Referee shall be borne equally by RBS and Sempra Energy. Purchaser, each other Indemnified Party, RBS and Sempra Energy shall be entitled to rely on each statement delivered pursuant to this section for all purposes under this Article IX.

(iv) Sempra Energy shall have sole liability in respect of claims for indemnification pursuant to Sections 9.2(d) and 9.2(e).

(c) The Purchaser shall have no liability with respect to claims under Section 9.3(a) until the total of all Damages (other than De Minimis Damages) with respect to such matters exceeds ***, and then only for the amount in excess thereof. In no event shall the Purchaser’s aggregate liability for indemnification under Section 9.3(a) exceed ***. The Purchaser shall have liability under Section 9.3(a) only if the Purchaser receives notice of any claim from the Indemnified Person, specifying the factual basis of the claim in reasonable detail and specifying, if known, the amount claimed, within the applicable survival period as defined in Section 9.1.

(d) Solely for purposes of calculating Damages for which an indemnity obligation arises under this Article IX, in respect of any breach of any covenant or obligation, or any representation or warranty, contained in this Agreement, any express qualifications or limitations set forth in such covenant or obligation, or representation or warranty (other than the representation and warranty set forth in Section 3.3(b)), as to materiality or “Company Material Adverse Effect” (or other similar materiality qualifier) contained therein, shall be disregarded.

(e) Notwithstanding anything herein to the contrary, no Indemnified Person shall be entitled to indemnification or reimbursement under any provision of this Agreement for any amount to the extent such Person or its Affiliates has been indemnified or reimbursed for such amount under any other provision of this Agreement or any Related Agreement or by any Third Party.

(f) Except in the case of fraud, from and after the Closing, the exclusive remedy for any Indemnified Person for Damages or other monetary damages arising from a

*** Material has been omitted pursuant to a request for confidential treatment and has been filed separately.

breach of this Agreement shall be the indemnification provided under this Article IX. There shall be no remedy at law for De Minimis Damages arising out of the events or circumstances described in Sections 9.2(a) or 9.3(a) (except as described in Section 9.2(a)). Nothing in this Section 9.4(f) or elsewhere in this Agreement shall interfere with or impede the operations of Section 10.13 or the remedies available under this Agreement or the Related Agreements or a Party’s right to seek equitable remedies (including specific performance or injunctive relief) to enforce any covenant in this Agreement to be performed after the Closing.

(g) In no event shall Damages be subject to indemnification under Section 9.2 or Section 9.3 to the extent such Damages were included as liabilities (including any reserves in respect of such Damages) in the Final Closing Balance Sheet; provided, that any Damages in excess of the amounts so included as liabilities (including any reserves in respect of such Damages) in the Final Closing Balance Sheet shall be subject to indemnification hereunder in accordance with and subject to the terms, conditions and limitations of this Article IX.

(h) NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL AN INDEMNIFYING PERSON BE LIABLE FOR (A) ANY PUNITIVE DAMAGES OR (B) ANY LOST PROFITS OR CONSEQUENTIAL, SPECIAL OR INDIRECT DAMAGES, EXCEPT, IN THE CASE OF (B), TO THE EXTENT SUCH LOST PROFITS OR DAMAGES ARE (X) NOT BASED ON ANY SPECIAL CIRCUMSTANCES OF THE INDEMNIFIED PERSON AND (Y) THE NATURAL, PROBABLE AND REASONABLY FORESEEABLE RESULT OF THE EVENT THAT GAVE RISE THERETO OR THE MATTER FOR WHICH INDEMNIFICATION IS SOUGHT HEREUNDER; provided, however, that if an Indemnified Person is held liable to a Third Party based on any final judgment of a court of competent jurisdiction for any such Damages and the applicable indemnifying party is obligated to indemnify such Indemnified Person for the matter that gave rise to such Damages, then such indemnifying party shall be liable for, and obligated to reimburse such Indemnified Person for such Damages.

(i) In no event shall Damages be subject to indemnification under (i) Section 9.2(a) if and to the extent such Damages are duplicative of Damages that are subject to indemnification under Section 9.2(b), 9.2(c), 9.2(d) or 9.2(e) or (ii) Section 9.3(a) if and to the extent such Damages are duplicative of Damages that are subject to indemnification under Section 9.3(b).

Section 9.5. Third-Party Claims. (a) Promptly (and in any event within thirty (30) days) after receipt by a Person entitled to indemnification under Section 9.2 or Section 9.3 of notice of the assertion of a Third-Party Claim, such Indemnified Person shall give notice to the Person or Persons obligated to indemnify under such Section (each, an “Indemnifying Person”) of the assertion of such Third-Party Claim; provided, that the failure to notify the Indemnifying Person shall not relieve the Indemnifying Person of any liability that it may have to any Indemnified Person, except to the extent that the Indemnifying Person demonstrates that the defense of such Third-Party Claim is actually and materially prejudiced by the Indemnified Person’s failure to give such notice.

(b) If an Indemnified Person gives notice to the Indemnifying Person pursuant to Section 9.5(a) of the assertion of a Third-Party Claim, the Indemnifying Person shall be entitled to participate in the defense of such Third-Party Claim and, to the extent that it wishes (unless (i) the Indemnifying Person is also a Person against whom the Third-Party Claim is made and the Indemnified Person determines in good faith that joint representation would be inappropriate, (ii) greater than 50% of the Damages are reasonably anticipated to be incurred by the Indemnified Person because such Damages constitute De Minimis Damages or exceed the applicable maximum limit (if any) for indemnification contained in Section 9.4, (iii) material equitable or other non-monetary relief is sought from any Indemnified Person pursuant to such Third-Party Claim, (iv) the claim is brought by a Governmental Body (except for claims relating to Taxes), (v) the claim relates to Taxes and is subject to indemnification under Section 9.2, except to the extent that the claim relates to a Pre-Closing Period or (vi) the Indemnifying Party has failed or is failing, or, if more than one Party is obligated to indemnify the Indemnified Person under Section 9.2 but such Parties have failed or are failing, to prosecute or defend diligently the Third-Party Claim after written notice specifying the grounds of such failure and which failure has not been remedied reasonably promptly) to assume the defense of such Third-Party Claim. Notwithstanding the foregoing, (i) in the case of a Third-Party Claim for Taxes relating to a Straddle Period, the Indemnified Person and the Indemnifying Person shall jointly control such Third-Party Claim and (ii) in the case of a Third Party Claim arising out of or relating to any California Litigation Sempra Energy shall control such Third-Party Claim. After notice from the Indemnifying Person to the Indemnified Person of its election to assume the defense of such Third-Party Claim, the Indemnified Person shall have the right (but not the duty) to participate in the defense of such Third-Party Claim and to employ separate counsel of its own choice for such purpose; provided that, so long as the Indemnifying Person diligently conducts such defense, the Indemnifying Person shall not be liable to the Indemnified Person under this Article IX for any fees of other counsel or other expenses with respect to the defense of such Third-Party Claim, in each case incurred by the Indemnified Person in connection with the defense of such Third-Party Claim after the Indemnifying Party assumes control of the defense of such Third-Party Claim, other than reasonable costs of investigation. If the Indemnifying Person assumes the defense of a Third-Party Claim, such assumption will, unless additional information at the time of the assumption emerges to change this conclusion, conclusively establish for purposes of this Agreement that the claims made in that Third-Party Claim are within the scope of and subject to indemnification (but no such assumption shall affect the applicability of any limit on indemnification contained in Section 9.4). No compromise or settlement of Third-Party Claims may be effected by the Indemnifying Person without the Indemnified Person’s consent (which consent shall not be unreasonably withheld or delayed) or by the Indemnified Person without the Indemnifying Person’s consent (which consent shall not be unreasonably withheld or delayed) unless the Third Party Claim does not relate to Taxes and (A) there is no finding or admission of any material violation of Legal Requirement, (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Person and (C) the compromise or settlement expressly unconditionally releases the Indemnified Person and its Affiliates from all liabilities and obligations with respect to such Third-Party Claim. No Person shall have any liability with respect to any compromise or settlement of such Third-Party Claims effected without its consent if required pursuant to the immediately preceding sentence. If notice is given to an Indemnifying Person of the assertion of any Third-Party Claim and the Indemnifying Person does not, within twenty (20) days after the Indemnified Person’s notice is given, give notice to the

Indemnified Person of its election to assume the defense of such Third-Party Claim, the Indemnifying Person will be bound by any determination made in such Third-Party Claim.

(c) With respect to any Third-Party Claim subject to indemnification under this Article IX: (i) both the Indemnified Person and the Indemnifying Person, as the case may be, shall keep the other Person reasonably informed of the status of such Third-Party Claim and any related Proceedings at all stages thereof where such Person is not represented by its own counsel, and (ii) the Parties agree to render to each other such assistance as they may reasonably require of each other and to cooperate in good faith with each other in order to ensure the proper and adequate defense of any Third-Party Claim; provided, that the Indemnifying Party shall pay the reasonable Third Party out-of-pocket expenses incurred in providing such cooperation (including reasonable legal fees and disbursements) by the Party providing such cooperation but shall not be required to compensate such Party for time spent by its officers, directors, employees or agents in such cooperation.

Section 9.6. Other Claims. A claim for indemnification to the extent not resulting from a Third-Party Claim may be asserted by written notice to the Party from whom indemnification is sought and, unless disputed by the Indemnifying Person by delivery of a written dispute notice to the Party seeking indemnification within 60 days after receipt by the Indemnifying Person of claim for indemnification, shall be deemed agreed by all Parties, final and undisputed and shall be paid by any such Indemnifying Party promptly, but in no event more than 45 days after receipt of such undisputed claim for indemnification. If the Indemnifying Person has timely disputed its indemnity obligations for any Damages with respect to such claim, the Parties shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of jurisdiction determined pursuant to Section 10.5.

Section 9.7. Duty to Mitigate. Nothing herein shall relieve a Party of its common-law duty to mitigate Damages. Without limiting the foregoing, each Party shall (and shall, to the extent it has authority and is permitted to do so, cause each other Section 9.2 Indemnified Person to, with respect to the Purchaser, and each other Section 9.3 Indemnified Person to, with respect to the Seller Parents) take commercially reasonable steps to mitigate all Damages after becoming aware of any event which could reasonably be expected to give rise to any Damages that are indemnifiable hereunder, including, as applicable, pursuing any counterclaim, offset, insurance settlement or other claim which could result in a recovery that would reduce the Indemnifying Person’s liability under this Agreement.

Except as otherwise expressly provided in this Agreement, each of the Parties shall bear its own costs and expenses (and the Seller Parents shall bear the costs and expenses of the Business to the extent incurred during or related to periods as of and prior to the Closing Date) in connection with the preparation, negotiation and execution of this Agreement and the Related Agreements and the consummation of the transactions

contemplated hereby and thereby including, without limitation, legal, financial advisory and consulting fees.

Section 10.2. Public Announcements and Confidentiality. None of the Parties nor their respective Subsidiaries or Affiliates shall issue or cause the publication of this Agreement, any Related Agreement or any press release or other public announcement or communication with respect to the transactions contemplated hereby without the prior written consent of each of the other Parties hereto (which consent shall not be unreasonably withheld or withdrawn) except to the extent a Party’s counsel deems necessary or advisable in order to comply with the requirements of any Legal Requirement or the regulations or policies of any securities exchange or other similar regulatory body (in which case the disclosing Party shall give the other Parties notice as promptly as is reasonably practicable of any required disclosure to the extent permitted by applicable Legal Requirements), shall limit such disclosure to the information required to comply with such Legal Requirement or regulations, and shall use reasonable efforts to accommodate any suggested changes to such disclosure from the other Parties to the extent reasonably practicable.

Section 10.3. Tax Matters.

(a) The Parties shall, and shall cause their Subsidiaries to, cooperate fully, as and to the extent reasonably requested by any other party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes (including any Tax Returns to be filed by the Seller Parties). Such cooperation shall include the retention of books and records with respect to Tax matters relating to any Pre-Closing Period until the expiration of any applicable statute of limitations and (upon such other party’s request) the provision of records and information reasonably relevant to any such Tax Return, audit, litigation, or other proceeding (to the extent relating to the Business or the Company) or to the preparation of financial statements (to the extent as it relates to Tax matters) and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

(b) Notwithstanding any provision of this Agreement to the contrary, all Transfer Taxes incurred in connection with this Agreement and the transactions contemplated hereby shall be borne fifty percent (50%) by the Purchaser and fifty percent (50%) by the Seller Parties. The Parties shall, and shall cause their Subsidiaries to, cooperate in timely making all filings, Tax Returns, reports and forms as may be required to comply with the provisions of applicable Tax Laws relating to such Transfer Taxes. The Parties shall take all commercially reasonable steps, and agree to cooperate, to minimize the Transfer Taxes due in connection with this Agreement and the transactions contemplated hereby. For purposes of this Agreement, “Transfer Taxes” shall mean all transfer, sales, use, stamp duty, stamp duty reserve tax, stamp duty land tax, documentary, registration and other such taxes (including all applicable real estate transfer taxes, but excluding VAT).

(c) The Parties agree to treat any indemnification payment made pursuant to Article IX as an adjustment to the Purchase Price hereunder for all Tax purposes, unless otherwise required by a Legal Requirement.

(d) (i) The Parties hereto will agree to allocate the Purchase Price (plus assumed liabilities, to the extent properly taken into account under Section 1060 of the Code) in accordance with Section 1060 of the Code to all of the assets of the Company, pursuant to this Section 10.3(d). The Parties shall use commercially reasonable efforts to agree on such allocation within sixty (60) Business Days after the Closing Date.

(ii) If the Parties have not agreed on the allocation within sixty (60) Business Days after the Closing Date, then the Parties shall each have the right to deliver notice to the other Party (the “Allocation Dispute Notice”) of its intent to refer the matter for resolution to the Accounting Expert. The Parties will each deliver to the other and to the Accounting Expert a notice setting forth in reasonable detail their proposed allocations. Within thirty (30) Business Days after receipt thereof, the Accounting Expert will deliver the final allocation and provide a written description of the basis for its determination of the allocations therein; provided that if the Accounting Expert requests a hearing before making a determination, such hearing shall be held within twenty (20) Business Days of the Parties’ delivery of their respective proposed allocations and the delivery of the final allocation shall be made within ten (10) Business Days of such hearing. The fees and expenses of the Accounting Expert shall be apportioned among the Parties as the Accounting Expert shall determine. Each Party will bear the costs of its own counsel, witnesses (if any) and employees.

(iii) The Parties agree to act in accordance with the final allocation determined pursuant to this Section 10.3(d) for all Tax purposes (including for purposes of the filing of any Tax Return), subject to any Legal Requirement to the contrary. The Parties will revise the allocation to the extent necessary to reflect any payment made pursuant to Section 2.5(d). In the case of any such payment, the Purchaser shall promptly prepare and deliver (with reasonable assistance as requested from the Seller) to the Seller a revised allocation, and the Parties shall follow the procedures outlined above with respect to review, dispute and resolution in respect of such revision.

Section 10.4. Notices. All notices, Consents, waivers and other communications required or permitted by this Agreement shall be in writing and shall be deemed given to a Party when (a) delivered to the appropriate address by hand or by nationally recognized overnight courier service (costs prepaid), (b) sent by facsimile or e-mail with confirmation of transmission by the recipient, or (c) received or rejected by the addressee, if sent by certified mail, return receipt requested, in each case to the following addresses, facsimile numbers or e-mail addresses and marked to the attention of the person (by name or title) designated below (or to such other address, facsimile number, e-mail address or person as a Party may designate by notice to the other Parties):

Section 10.5. Submission to Jurisdiction; Waiver of Jury Trial. Each Party agrees that it shall bring any action or proceeding in respect of any questions, claims, disputes, remedies or Damages arising out of or related to this Agreement or the Related Agreements or the transactions contained in or contemplated hereby or thereby exclusively in the United States District Court for the Southern District of New York (the “Chosen Court”), and, solely in connection with claims arising under this Agreement or the Related Agreements or the transactions that are the subject hereof and thereof (i) irrevocably submits to the exclusive jurisdiction of the Chosen Court, (ii) waives and agrees not to assert any objection to laying venue in any such action or proceeding in the Chosen Court, (iii) waives any objection that the Chosen Court are an inconvenient forum or do not have jurisdiction over any Party, (iv) agrees that service of process upon such Party in any such action or proceeding shall be effective if notice is given in accordance with Section 10.4 and (v) agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in any other jurisdictions by suit on the judgment or in any other manner provided by applicable Legal Requirements. This Section 10.5 shall not limit the jurisdiction of the Accounting Expert set forth in Section 2.5(c) or

Section 10.3, or the jurisdiction of the Referee set forth in Section 9.4(b)(iii), although claims may be asserted in the Chosen Court for purposes of enforcing the respective jurisdictions and judgments of the Accounting Expert and the Referee. EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LEGAL REQUIREMENTS, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 10.6. Waiver; Remedies Cumulative. The rights and remedies of the Parties to this Agreement are cumulative and not alternative. Neither any failure nor any delay by any Party in exercising any right, power or privilege under this Agreement or any of the documents referred to in this Agreement will operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege. To the maximum extent permitted by applicable Legal Requirements, (a) no claim or right arising out of this Agreement or any of the documents referred to in this Agreement can be discharged by one Party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other Party; (b) no waiver that may be given by a Party will be applicable except in the specific instance for which it is given; and (c) no notice to or demand on one Party will be deemed to be a waiver of any obligation of that Party or of the right of the Party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

Section 10.7. Entire Agreement and Modification. This Agreement supersedes all prior agreements, whether written or oral, between the Parties with respect to its subject matter (including any letter of intent between the Parties related to the subject matter of this Agreement) and constitutes (together with the Schedules, Exhibits, the Seller Disclosure Letter, the Purchaser Disclosure Letter and other documents delivered pursuant to this Agreement including the Related Agreements) a complete and exclusive statement of the terms of the agreement between the Parties with respect to its subject matter; provided, that this Section 10.7 shall not apply to the Non-Disclosure Agreement, which shall remain in full force and effect in accordance with its terms except as provided by Section 7.5(d). This Agreement may not be amended, supplemented, or otherwise modified except by a written agreement executed by all Parties.

Section 10.8. Assignments, Successors and no Third-Party Rights. No Party may, in whole or in part, assign any of its rights or interests or delegate any of its obligations under this Agreement without the prior written consent of each of the other Parties, and any attempt to do so will be void; provided, that without prior written consent any Party may assign any of its rights or delegate any of its obligations under this Agreement to any wholly-owned Subsidiary so long as the assigning or delegating Party retains its obligations under this Agreement and so long as such assignment would not reasonably be expected to materially delay or adversely affect the consummation of the transactions contemplated hereby or otherwise adversely affect the performance of any obligation hereunder and, in the case of the Purchaser’s assignment or delegation, so long as the Guaranty (i) is applicable to, and guarantees, any performance or payment obligations of such assignee or delegee to the same extent applicable to

the Purchaser and (ii) is not otherwise affected. Subject to the preceding sentence, and except as otherwise expressly provided in Sections 9.2 and 9.3, this Agreement shall apply to, be binding in all respects upon and inure to the benefit of the successors and permitted assigns of the Parties. Nothing expressed or referred to in this Agreement shall be construed to give any Person other than the Parties to this Agreement any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision of this Agreement, except such rights as shall inure to a successor or permitted assignee pursuant to this Section 10.8 and except for such rights of any Indemnified Person under Article IX.

Section 10.9. Severability. If any provision (or part thereof) of this Agreement is held illegal, invalid or unenforceable under any present or future Legal Requirement, (i) the Parties shall negotiate in good faith to replace such provision with a suitable and equitable substitute therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such illegal, invalid or unenforceable provision, and to the extent such substitution would not be valid or enforceable, (ii)(a) such provision (or part thereof) shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision (or part thereof) had never comprised a part hereof, and (d) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision (or part thereof) or by its severance herefrom.

Section 10.10. Construction. The headings of Articles and Sections in this Agreement are provided for convenience only and shall not affect its construction or interpretation. All references to “Articles,” “Sections” and “Schedules” refer to the corresponding Articles, Sections and Schedules of this Agreement.

Section 10.11. Governing Law. This Agreement shall be governed by and construed in accordance with the substantive laws of the State of New York.

Section 10.12. Execution of Agreement. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original copy of this Agreement and all of which, when taken together, shall be deemed to constitute one and the same agreement. The exchange of copies of this Agreement and of signature pages by facsimile or other electronic transmission shall constitute effective execution and delivery of this Agreement as to the Parties and may be used in lieu of the original Agreement for all purposes. Signatures of the Parties transmitted by facsimile or other electronic means shall be deemed to be their original signatures for all purposes.

Section 10.13. Specific Performance. Without intending to limit the remedies available to the Parties hereunder, each Party acknowledges that a breach of, conflict with, or failure to perform or comply with, any of the covenants contained in this Agreement may result in material irreparable injury to the other Parties or their respective Affiliates for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of such a breach or threat thereof, to the fullest extent permitted by any Legal Requirement, each Party shall be entitled to seek a temporary restraining order and/or a preliminary or permanent injunction restraining the activities prohibited hereby or such other relief as may be required to specifically enforce any of the covenants contained herein, and to the fullest extent permitted by law, such Party agrees not to oppose the granting of such

injunctive relief on the basis that monetary damages are an adequate remedy. Each Party hereby agrees and consents that such injunctive relief may be sought in accordance with Section 10.5 hereto.

Section 10.14. VAT. If any payment by the Purchaser to Seller or a Seller Parent under this Agreement as contemplated hereby constitutes the consideration for a taxable supply for VAT purposes, then the recipient of the payment shall be fully responsible for, and shall fully indemnify and hold the Purchaser harmless for, any VAT chargeable on that supply, provided that the Parties shall negotiate in good faith and cooperate in taking all reasonable steps to avoid or minimize any VAT chargeable or assessable on that supply.

Section 10.15. Withholding Taxes. The Purchaser, its Affiliates, their respective agents and, effective upon the Closing, the Company shall be entitled to deduct and withhold from any amount otherwise payable to any Person pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign Tax Law. If any amount is so withheld, such amount shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which the Purchaser, its Affiliate, the agent or the Company, as the case may be, made such deduction and withholding. The Purchaser shall notify the Seller as soon as practicable and in any event reasonably in advance of the Closing Date if the Purchaser has reason to believe that it would be required by Tax Law to deduct or withhold any amount from the Purchase Price, and the Parties shall negotiate in good faith and cooperate in taking all reasonable steps to avoid or minimize any such obligation to deduct or withhold any amount from the Purchase Price. For the avoidance of doubt, Section 10.15 shall not prejudice the rights of the Purchaser to indemnification under Section 9.2(c)(ii) in respect of any Taxes that were required to be withheld with respect to the Purchase Price or any portion thereof.

Section 10.16. Regulated Utilities. Notwithstanding any provision hereof or of any Related Agreement, no covenant or restriction set forth herein or therein shall require any Sempra Utility (or any other Person now owned by Sempra Energy or any of its Affiliates or hereafter acquired that is subject to cost-based rate regulation and regulation as to service by any state, federal or foreign governmental regulation and owns or operates facilities used for (i) the generation, transmission, or distribution of electric energy for sale, (ii) the distribution of natural or manufactured gas for heat, light, or power or (iii) the collection, treatment and distribution of water for sale) to take or refrain from taking any action.
