The Gas and Power Business, as it refers to business conducted by UBS and its Affiliates after the Closing Date, excludes the already-existing risk management and financial services business of UBS and its Affiliates (including its business relating to interest rate, foreign exchange and equity derivatives), as it may be conducted from time to time, including as it may be conducted with counterparties in the Gas and Power Business. The Enron Parties, along with certain of their Affiliates, have filed voluntary petitions (the "Petitions") for relief commencing cases (collectively, the "Chapter 11 Case") under chapter 11 of Title 11 of the United States Code (the "Bankruptcy Code") in the United States Bankruptcy Court for the Southern District of New York (the "Bankruptcy Court").

Enron and certain of its subsidiaries intend to continue in the management and possession of their assets and businesses as debtors-in-possession in the Chapter 11 Case pursuant to Sections 1107 and 1108 of the Bankruptcy Code and subject to the terms and conditions of this Agreement. In consideration of the mutual benefits to be derived from this Agreement and of the representations, warranties, conditions, agreements and promises contained herein and other good and valuable consideration, the parties agree as follows: Article I THE TRANSACTIONS 1.1.

(a) Until the Closing, UBS and the Enron Parties each agree that all financial or other information about UBS, any of its Affiliates or the Enron Parties or any of their Affiliates, or other information of a confidential or proprietary nature, disclosed to the other at any time in connection with the proposed transaction shall be kept confidential by the party receiving such information and shall not be disclosed to any person or used by the receiving party (other than to its Affiliates, agents, employees, lenders, the Creditors' Committee and its professionals, or counsel or in connection with the transactions contemplated by this Agreement) except: (i) with the prior written consent of the disclosing party; (ii) as may be required by applicable law, court or administrative process; (iii) such information which may have been acquired or obtained by such party (other than through disclosure by the other party in connection with the transactions contemplated by this Agreement or resulting from the breach by a third party of a confidentiality agreement without knowledge by the receiving party of the breach); or (iv) such information which is or becomes generally available to the public other than as a result of a violation of this provision. On and after the Closing, the Enron Parties and UBS shall comply with the confidentiality provisions of the License Agreement. 10 (b) The parties acknowledge that each party's damages at law would be an inadequate remedy for the breach by any of the other parties of any provision of this Section 3.7, and agree in the event of such breach that the non-breaching parties may obtain temporary and permanent injunctive relief restraining such breaching parties from such breach, and, to the extent permissible under applicable statutes and rules of procedure, a temporary injunction may be granted immediately upon the commencement of any such suit. Nothing contained in this Agreement shall be construed as prohibiting a party from pursuing other remedies available at law or in equity for such breach or threatened breach of this Section 3.7 of this Agreement. 3.8. Employee Matters. (a) The Enron Parties shall, and shall cause its Controlled Affiliates to, use commercially reasonable efforts to retain through the Closing all employees necessary or appropriate in UBS's judgment for UBS to operate the business contemplated by the License Agreement, including trading professionals covered by Section 4.2 and employees in the areas of information technology, operations, credit, market risk, research/fundamentals, human resources, accounting and legal functions (the "Eligible Employees"). The Enron Parties shall, and shall use their reasonable best efforts to cause their Controlled Affiliates to, provide such assistance as is reasonably requested by UBS in the process of UBS or its Affiliates hiring such of the Eligible Employees as UBS desires, subject to applicable law. The Enron Parties shall not, and shall not permit their Controlled Affiliates to, take any action to discourage any of the Eligible Employees from becoming an employee of UBS or its Affiliates. UBS shall have no obligation to offer employment to or hire any particular Eligible Employees. (b) Beginning on the date hereof, the Enron Parties shall permit and facilitate UBS's and its Affiliates' communication and meetings with the Eligible Employees, at reasonable times and upon reasonable notice and at Enron locations or other locations reasonably requested by UBS, concerning UBS's plans, operations, business, customer relations and general personnel matters and to interview the Eligible Employees and review such information concerning the Eligible Employees as UBS may reasonably request (subject to obtaining any legally required written permission of any affected Eligible Employee and to other applicable Law). The Enron Parties shall provide to UBS the employment files and records of any Eligible Employee hired by UBS (subject to obtaining any legally required written permission of any affected Eligible Employee and to other applicable Law). (c) The Enron Parties, on behalf of themselves and their Controlled Affiliates, hereby release each Eligible Employee hired by UBS or any Affiliate thereof as contemplated by this Agreement, effective as of the date of such hiring, from (i) any continuing employment obligations (whether under any employment contract or otherwise), (ii) any noncompetition, nonsolicitation and confidentiality obligations, to the extent they are not assigned to UBS or an Affiliate thereof, and (iii) any liabilities arising out of such Eligible Employee's lawful performance of his or her duties while an employee of an Enron Party and/or its Affiliates for matters relating to the periods prior to such hiring by UBS or Affiliate of UBS; provided however, that nothing herein shall constitute or be deemed to be a release of any Eligible Employee from liability arising out of (w) any material unauthorized trading activities, (x) any actions taken that were a material violation of an Enron Party's corporate policies, (y) any gross negligence, willful misconduct or knowing violation of law on the part 11 of such Eligible Employee, or (z) any special payments to such Eligible Employees made in the month prior to the Bankruptcy filing. (d) By the first anniversary of the Closing, UBS shall cause to be paid cash stay put or retention bonuses equal to $11,000,000 in the aggregate (before tax withholdings or other required deductions) to the group of employees agreed to by Enron and UBS in the Gas and Power Business hired by UBS or its Affiliates, with the particular employees receiving such bonuses, the amounts thereof and the time of payment within such year being determined by UBS in its sole discretion. UBS shall pay interest to Enron at a rate per annum equal to 30 day LIBOR (as determined by UBS) on any portion of the $6,000,000 referred to in Section 4.2(i) to the extent it has not been spent by UBS pursuant to this Section 3.8(d), it being understood that for purposes of calculating interest, the $6,000,000 shall be deemed to be applied to pay such stay put or return bonuses prior to any other UBS funds. 3.9. Taxes. (a) The Enron Parties and UBS shall each bear 50% of all stamp, transfer, excise, documentary, sales, use, registration and other similar taxes and fees (including any penalties and interest) arising out of or in connection with the transactions contemplated by this Agreement and the other agreements, documents and instruments executed pursuant hereto. The party responsible for filing any necessary tax returns and other documentation with respect to any such Taxes shall at its own expense properly file such return or other documentation and provide to the other parties evidence of filing and payment of all such taxes. The Enron Parties and UBS will reasonably cooperate with one another to lawfully minimize such taxes. Nothing in this Section 3.9(a) shall affect the provisions of Section 3.9(c). (b) Notwithstanding any other provision contained in this Agreement, the License Agreement and the other Related Agreements, the covenants contained in this Section 3.9 shall survive until 30 days after the expiration of the applicable statute of limitations (including extensions). (c) Notwithstanding any other provision contained in this Agreement, the License Agreement and the other Related Agreements, UBS shall be responsible for all taxes imposed on UBS or its Affiliates under Part IX of the Excise Tax Act (Canada) in respect of the transactions pursuant to the License Agreement and the other Related Agreements; provided, however, that UBS shall not be responsible for such taxes imposed in respect of any Royalty that is paid and required to be paid to Enron Canada Corp. by a non-resident (for the purposes of such Act) of Canada that is not registered for purposes of such Part IX. UBS agrees to cause any payor (that is registered for purposes of Part IX of the Excise Tax Act (Canada)) of a Royalty to Enron Canada Corp. to claim input tax credits in respect of such taxes and so long as the payor of a Royalty to Enron Canada Corp. is registered for purposes of Part IX of the Excise Tax Act (Canada), Enron Canada Corp. agrees to indemnify the Royalty payor for any Losses arising from the denial by Canada Customs and Revenue Agency of all or part of such credits; provided that the Royalty payor shall, to the extent requested by and at the cost of Enron Canada Corp., object to such denial and shall provide reasonable cooperation in respect of such objection. (d) All payments by UBS and its Affiliates, as the case may be, under this Agreement, the License Agreement and the other Related Agreements shall be made free and clear of, and without reduction for, any withholding taxes or other governmental charges. The preceding sentence shall not apply (i) 12 to a payment made to a payee that for purposes of the relevant withholding tax or governmental charge is no longer a resident of the country of which it was a resident on the Effective Date, (ii) to a Royalty payment, if any, made and required to be made to Enron Canada Corp.; provided, however, that before effecting any such withholding on payments to Enron Canada Corp., UBS will consult with Enron Canada Corp. regarding the need to withhold and alternatives that could reduce such withholding and shall use its best efforts to adopt such an alternative requested by Enron Canada Corp., so long as such alternative is not detrimental to UBS in UBS's judgment; and provided further, however, that UBS, to the extent requested by, and at the cost of, Enron Canada Corp., will cooperate with Enron Canada Corp. in connection with refund claims that Enron Canada Corp. seeks to pursue in respect of any amounts withheld by UBS or its Affiliates, and (iii) to a payment made to a payee to the extent that such withholding taxes or other governmental charges in respect of such payee exceed the amount of such taxes or charges that would have been imposed if the payee had been Enron. (e) Except to the extent inconsistent with either a change of law or a written determination by a taxing authority addressed to a party to this Agreement, the parties agree that the payments made pursuant to Article V of the License Agreement represent the fair market value of the licenses granted thereunder. The parties shall treat such payments, for all United States and Canadian income tax purposes, as royalties (within the meaning of Section 61(a)(6) of the Internal Revenue Code of 1986, as amended) in respect of such licenses and shall refrain from taking any position inconsistent with such treatment. The foregoing shall not apply to so much of the payments made pursuant to Article V of the License Agreement as does not exceed, in the aggregate, the depreciated book value of the assets transferred pursuant to Article III of the License Agreement as reflected on the Enron Parties' books and records as of the date of such transfer.

Effective upon the Closing, payments of indemnity pursuant to this Section 5.1(a) shall be made only through set offs made pursuant to Section 5.6. The disclosure of any matter by the Enron Parties pursuant to the exceptions for disclosure in the representations and warranties of such parties shall not limit the indemnity pursuant to clause (iii) above, such that the UBS Indemnified Parties shall be indemnified for the matters set forth in Schedules 2.1(f) and (g) to this Agreement. (b) UBS agrees to indemnify and hold harmless each Enron Party and its Affiliates, shareholders, partners, directors, officers, employees and other agents and representatives (the "Enron Indemnified Parties") from and against any and all liabilities, judgments, claims, settlements, losses, damages, fees, Liens, Taxes, penalties, obligations and expenses (including reasonable fees and disbursements of counsel) (collectively, "Enron Losses") incurred or suffered by any such person arising from, by reason of or in connection with: (i) any misrepresentation or breach of any representation or warranty of UBS contained in this Agreement; (ii) any breach of any covenant or agreement of UBS contained in this Agreement, other than breaches the consequences of which are immaterial in the context of this Agreement; (iii) any and all liabilities or obligations of UBS for the Assumed Obligations or the failure by it to pay or discharge the same; and (iv) any and all actions, suits, proceedings, demands, orders, rulings, decrees, judgments, costs and legal and other expenses incident to any of the matters referred to in clauses (i) through (iii) of this Section 5.1(b); provided, however, that the Enron Indemnified Parties shall not be entitled to indemnification under clause (i) above until the aggregate amount of Enron Losses (together with Enron Losses under clause (i) of Section 19.1(b) of the License Agreement, without duplication) exceeds $5,000,000 (the "Enron 17 Threshold"), at which point the Enron Indemnified Parties shall be entitled to indemnification for all Enron Losses, without giving effect to the Enron Threshold, that in the aggregate exceed $2,500,000; provided further that the maximum amount for which the Enron Indemnified Parties shall be entitled to indemnification under clause (i) above (together with clause (i) of Section 19.1(b) of the License Agreement, without duplication) shall be $100,000,000. 5.2.

Procedures Relating to Third Party Claims. (a) In order for an indemnified party to be entitled to any indemnification provided for under this Article V arising from, by reason of, or otherwise in connection with an asserted or unasserted claim or demand made or which might be made by any Person against the indemnified party (a "Third Party Claim"), the indemnified party must send reasonably prompt notice to the indemnifying parties in writing of the Third Party Claim, including the nature and basis of such claim to the extent known by the indemnified party (the "Indemnification Notice"); provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the indemnifying parties have been materially and actually prejudiced as a result of such failure. Each party shall provide to the other parties, upon such other parties' written request, reasonable access during normal business hours to the books, records and personnel in their possession or under their control which are reasonable necessary to verify such claim. UBS shall defend all Third Party Claims against it for which it may seek indemnity hereunder or under the License Agreement with a degree of diligence consistent with UBS's customary defense of litigation against it. (b) If a Third Party Claim is made against an indemnified party, the indemnified party shall allow the indemnifying party to consult with the indemnified party regarding the defense of such Third Party Claim, including any settlement thereof, and the indemnifying party shall be entitled to participate in the defense thereof, it being understood that the indemnified party shall control the defense of such Third Party Claim and shall not be required to take any action that may jeopardize any attorney-client privilege. An indemnified party shall not agree to settle any Third Party Claim for monetary damages without the consent of the indemnifying party (which consent shall not be unreasonably withheld or delayed). 5.4. Procedures Related to Claims other than Third Party Claims. In the event any indemnified party should have a claim for indemnification against the indemnifying parties under this Article V that does not involve a Third Party Claim being asserted against or sought to be collected from such indemnified party, the indemnified party shall deliver notice of such claim with reasonable promptness to the indemnifying parties. The failure by any indemnified party so to notify the indemnifying parties shall not affect the indemnification provided hereunder except to the extent the indemnifying parties have been materially and actually prejudiced as a result of such failure. 18 5.5. Calculation of Indemnity Payments. The amount of any indemnity payment shall be decreased to take account of the net present value of any reasonably expected net Tax benefits to the indemnified party (using a discount rate of 10% per annum) and increased to take account of the net present value of any net Tax cost to the indemnified party that is reasonably expected by the indemnified party (using a discount rate of 10% per annum) arising from the receipt of any payment hereunder (grossed up for such increase) as calculated in good faith by the indemnified party. 5.6. Right of Set-Off. UBS (or its Affiliates on its behalf) may set off any amounts owed to UBS (or any of its Affiliates) by any Enron Party or any of its Controlled Affiliates pursuant to this Article V, any of the other provisions of this Agreement, any Related Agreement or any other document or agreement contemplated hereby or thereby against any amounts to be paid to an Enron Party pursuant to the License Agreement or any other Related Agreement. Article VI MISCELLANEOUS 6.1. Entire Agreement.
