Any insurance proceeds exceeding the cost of repair of the damaged Asset shall be an Excluded Asset. Notwithstanding the foregoing, prior to the Effective Time, if the value of the Assets destroyed or damaged exceed Twenty-Five Million Dollars ($25,000,000), then Buyer may terminate this Agreement. - 70 - 12.09 Relationship of the Parties.

If both Parties have liability or potential liability at the site and either Party is not a formal party to an action specified in clauses (i) or (ii) of the preceding sentence, and the Party named in such action is being held responsible or potentially responsible for the other Party's liability, then the Parties will divide the risk on a proportionate basis according to the respective volume of Hazardous Substances deposited in such waste sites by Buyer on or after the Effective Time, which shall be at Buyer's risk, or by Seller prior to the Effective Time, which shall be Seller's risk. Notwithstanding anything to the contrary in the Agreement (i) this Section 13.03 is an independent risk allocation method not governed by, or subject to, Section 13.01, and (ii) this Section 13.03 shall continue in effect into perpetuity; provided further that, in any case where only one of the Parties has contributed waste at a site covered by this Section 13.03, such Party will remain solely responsible for such contribution. - 77 - 13.04 Environmental Coordination Committee. Within thirty (30) days of the Effective Time, each Party will designate two representatives, one legal and one technical, to consult on coordination of their respective obligations under Article 13.

ARTICLE 15 ARBITRATION 15.01 Dispute Resolution. Any controversy or claim ("Claim"), whether based on contract, tort, statute or other legal or equitable theory (including but not limited to any claim of fraud, misrepresentation or fraudulent inducement or any question of validity or effect of this Agreement including this section) arising out of or related to this Agreement (including any amendments or extensions), or the breach or termination thereof, shall be settled by mediation and consultations between the Parties initiated upon the Notice of any Party. In the event of failure of such mediation and consultations to settle such Claim in a manner acceptable to all Parties within thirty (30) days following the Notice, then any such Claim shall be settled by binding arbitration in accordance with this provision and the then current CPR Institute for Dispute Resolution Rules for Non- Administered Arbitration of Business Disputes. The arbitration shall be governed by the United States Arbitration Act, 9 U.S.C. Sections 1-16, to the exclusion of any provision of state law inconsistent therewith or which would produce a different result, and judgment upon the award rendered by the arbitrator may be entered by any court having jurisdiction. - 90 - 15.02 Place. The arbitration shall be held in Houston, Texas. 15.03 Arbitrators. There shall be three (3) independent and impartial arbitrators of whom Seller appoints one (1) and Buyer appoints one (1) and the third of which shall be appointed by the two (2) Party-appointed arbitrators in accordance with the arbitration rules. The arbitrators shall determine the Claims of the Parties and render a final award in accordance with the substantive law of the State of Texas, excluding the conflicts provisions of such law. The arbitrators shall specify the reasons for the award in writing. 15.04 Statute of Limitations. Subject to Section 14.04, any Claim by a Party shall be time-barred if the asserting Party commences arbitration with respect to such Claim later than two (2) years after the cause of action accrues.

The arbitrator shall order the Parties to promptly exchange copies of all exhibits and witness lists, and, if requested by a Party, to produce other relevant documents, to answer up to ten (10) interrogatories (including subparts), to respond to up to ten (10) requests for admissions (which shall be deemed admitted if not denied) and to produce for deposition and, if requested, at the hearing all witnesses that such Party has listed and up to four (4) other persons within such Party's control. Any additional discovery shall only occur by agreement of the Parties or as ordered by the arbitrator upon a finding of good cause. 15.06 Costs. Each Party shall bear its own costs, expenses and attorneys' fees; provided that if court proceedings to stay litigation or compel arbitration are necessary, the Party who unsuccessfully opposes such proceedings shall pay all reasonable associated costs, expenses, and attorneys' fees in connection with such court proceeding. 15.07 Breach. The Parties recognize that irreparable injury will result from a breach of any provision of this Agreement and that money damages will be inadequate to fully remedy the injury. In order to prevent such irreparable injury, the arbitrator shall have the power to grant temporary or permanent injunctive or other equitable relief. Prior to the appointment of an arbitrator a Party may, notwithstanding any other provision of this Agreement, seek temporary injunctive relief from any court of competent jurisdiction; provided, that the Party seeking such relief shall (if arbitration has not already been commenced) simultaneously commence arbitration. Such court ordered relief shall not continue more than ten (10) days after the appointment of the arbitrator (or in any event for longer than sixty (60) days). - 92 - 15.08 Consent to Jurisdiction. The Parties hereby consent to the non-exclusive jurisdiction of the state or federal courts of Texas for the enforcement of any award rendered by the arbitrators. ARTICLE 16 TECHNOLOGY 16.01 Grants. Seller shall grant and hereby does grant to Buyer for Use in the operation of the Refinery, a non-exclusive, irrevocable (except as provided in this Article 16) royalty-free, paid-up license or sublicense (both, as the case may be, without a right to sublicense or transfer except as expressly provided in this Article 16) to Intellectual Property, which exists at the Effective Time and which is in Use in the Operations or which is needed to be Used in the Operations. By executing this Agreement, effective as of the Effective Time, the Buyer is assuming all relevant duties and obligations of Seller with respect to Intellectual Property under the Technology Transfer Agreement ("TTA") attached as Schedule 16.01, including the confidentiality obligations of Article 6 therein but excluding any liability under Section 12(c) of the TTA unless such liability arises as a result of the action or lack of action on behalf of Buyer other than using the Intellectual Property in a manner substantially similar to the manner in which it was used in Seller's Operations. For avoidance of doubt, this grant is revoked in the event that Equilon repurchases the Refinery at the time of said repurchase. - 93 - 16.02 Exclusions. For avoidance of doubt, in the grant provisions of Section 16.01, the sublicense of Intellectual Property by Seller does not include any intellectual property outside the grant of Section 2 of the TTA and the License Agreement between Seller and Texaco Development Corporation dated August 1, 1993. The foregoing shall not be construed to limit or modify Equilon's representation or warranty in Section 16.06 of this Agreement. 16.03 Licensed Technology Rights. (a) Assignable and Transferable Licensed Technology Rights. Seller agrees to transfer, as soon as reasonably possible, Licensed Technology Rights which, for purposes of definition under this Section, comprise agreements which are (i) freely transferable without the permission of the licensor or vendor, (ii) not in use by Seller or its Affiliates at the Effective Time and (iii) not required by Seller in the future for its own benefit. These Licensed Technology Rights are listed on Schedule 16.03(a). This transfer shall be made by assignment or sublicense as the case may be for all Licensed Technology Rights on Schedule 16.03(a). Any fees required to be paid for such transfer shall be paid solely by Buyer. (b) Non-assignable or non-transferable Licensed Technology Rights. Buyer recognizes that the Licensed Technology Rights listed on Schedule 16.03(b) are not freely assignable without the permission of the licensor or vendor. Seller, at the written request of Buyer, agrees to contact the licensor or vendor and seek a permitted transfer of the Licensed Technology Rights or obtention of a new license for Buyer. In that event, all fees and costs necessary to transfer the Licensed Technology Rights or to acquire a new license commensurate therewith to Buyer, shall be paid solely by Buyer. Seller shall make a good faith attempt to maintain the status quo of such non-assignable non- transferable Licensed Technology Rights until Buyer can secure transfer or a new license to Buyer. - 94 - (c) It is the intent of Buyer and Seller that all Licensed Technology Rights used in the Operations of the Refinery are included in either Schedule 16.03(a) or Schedule 16.03(b). However, both Buyer and Seller recognize that because of the complexity of the instant transaction it is possible that some Licensed Technology Rights may not have been scheduled under either Section 16.03(a) or (b). In that event, if any Licensed Technology Rights are not included on Schedules 16.03(a) or (b) and, if the lack of such Licensed Technology Rights results in a Material Adverse Effect on the operations of the Refinery, then Buyer and Seller will cooperate to attain, at the lowest possible cost, rights for Buyer to Use the Licensed Technology Rights. Any fees necessary to obtain such Licensed Technology Rights shall be shared equally by Buyer and Seller. (d) In any assignment or issuance of a sublicense to Buyer of Licensed Technology Rights, Buyer agrees to assume and will be subject to all applicable obligations of the assigned license or the master license necessary to enable Buyer to Use the Licensed Technology Rights in Buyer's operation of the Refinery. (e) Seller may terminate any assignment or sublicense made to Buyer under Section 16.03 if Buyer is materially in default of any of the material obligations undertaken by Buyer in the assignment or sublicense. Seller shall give Buyer written notice at least 30 days prior to the date of termination. The notice shall specifically identify the obligation breached, the facts constituting the default and state Seller's intent to terminate. If Buyer cures such default prior to the expiration of the 30 day period, the sublicense or assignment shall not terminate. The foregoing shall not apply to any assignment pursuant to which Seller does not retain any future liability. - 95 - 16.04 Confidentiality. (a) The confidentiality obligations of the Buyer with respect to Confidential Information (which for purposes of this Article 16 shall mean any technical proprietary, secret or confidential information relating to Intellectual Property disclosed by Seller, directly or indirectly to Buyer) under this Article 16 shall be as follows: (i) Nothing in this Article 16 shall restrict in any way the right of Seller or Seller's Affiliates to use or disclose or permit others to use or disclose Confidential Information, which it possesses and otherwise has a free right to use and disclose. (ii) With respect to Confidential Information comprising Intellectual Property, Buyer shall maintain such Confidential Information in confidence, and shall Use it solely for the operations of the Refinery. (iii) With respect to Licensed Technology Rights, each Party may use and disclose Confidential Information comprising Licensed Technology Rights but only to the extent permitted under the terms of any agreement with the third party licensor of same, as the case may be. (b) Except where provided otherwise with respect to Confidential Information whose disclosure and Use in Section 16.04(a) is governed by an agreement with a third party pertaining to Licensed Technology Rights, Buyer's obligation of confidentiality and restricted use in Section 16.04(a) above shall not apply to any information which Buyer can show by reasonable proof: - 96 - (i) was available to the public prior to or becomes available to the public subsequent to the receipt of such Confidential Information by Buyer pursuant to this Article 16 and through no fault of Buyer; or (ii) was in the possession of Buyer prior to the receipt of such Confidential Information by Buyer pursuant to this Article 16, and was not acquired by Buyer from a third party under and existing obligation of confidence; or (iii) is subsequently received by Buyer from a third party without an obligation of confidentiality; or (iv) is independently developed by an employee or employees of Buyer not having direct or indirect access to such Confidential Information of another party. For purposes of this Article 16, specific items of Confidential Information made available to Buyer under this Article 16 shall not be deemed to fall within any of the exceptions as set forth above merely because such items are embraced by more general information which falls within one or more exceptions, nor shall a combination of features be deemed to fall within such exceptions merely because the individual features fall with such exceptions. (c) Confidential Information, which is required to be disclosed, (i) by any applicable law, stock exchange rules or by any applicable judgment, order or decree of any governmental entity having jurisdiction or (ii) in connection with the preparation of tax returns, communications with governmental authorities with respect thereto or proceedings relating to taxes, may be disclosed, provided that Buyer only discloses such Confidential Information to the least extent practicable, and Buyer shall provide Seller with prompt and reasonable notice thereof so that Seller may seek a suitable protective order or other appropriate remedy and/or waive compliance with the provisions of this Article 16. In the event that such protective order or other remedy is not obtained or Seller waives compliance with the provisions of this Article 16, and Buyer is required to disclose such Confidential Information, Buyer will furnish only that portion of the Confidential Information which Buyer is required to disclose and, to the extent practicable, Buyer will exercise its best efforts to obtain reliable assurance that confidential treatment shall be accorded and such Confidential Information so furnished. - 97 - (d) Buyer shall have a right to disclose and Use with service providers, consultants, independent contractors and government agencies, all Confidential Information (unless prohibited by a Licensed Technology Right obligation), received from Seller but only if such recipient agrees to be bound pursuant to an obligation of confidentiality and nonuse comprising restrictions at least as stringent as provided herein. 16.05 Term and Termination. The grants made in Sections 16.01 and 16.03 shall not be subject to any term unless Seller repurchases the Refinery. 16.06 Representations and Warranties. Seller represents and warrants to Buyer as follows: (a) Seller has the right to grant the licenses of Intellectual Property as set forth in this Article 16; (b) to the Knowledge of Seller, except as set forth on Schedule 5.12, (i) there are no facts that would support a claim that Seller does not have the right, immediately prior to the Effective Time, to Use the intellectual property Used in Seller's Operations, which claim may result in a Material Adverse Effect; (ii) there are no facts or claims of ownership to any Intellectual Property having a Material Adverse Effect licensed or assigned to Buyer pursuant to this Article 16; (iii) there are no facts that would support a claim that may result in losses having a Material Adverse Effect, that Seller's Use of the Intellectual Property in the Operations of the Refinery licensed pursuant to this Article 16 has not infringed or otherwise violated any intellectual property right of a third party; and (iv) there are no facts that would support a claim that may result in losses having a Material Adverse Effect, that Use by Buyer in the operations of the Refinery of the Intellectual Property licensed pursuant to this Article 16 will infringe or otherwise violate any intellectual property right of a third party. - 98 - (c) Except as otherwise stated in this Article 16, ANY ORAL OR WRITTEN REPORT, DATA OR OTHER INFORMATION PROVIDED TO BUYER HEREUNDER, WHETHER PROVIDED UNDER LICENSE OR OTHERWISE, SHALL BE PROVIDED ON AN "AS IS" BASIS WITHOUT ANY WARRANTIES, EXPRESS OR IMPLIED INCLUDING BUT NOT LIMITED TO THE RESULTS OR EFFECTS OBTAINED THROUGH USE OF INFORMATION, OR THAT IT IS FIT FOR ANY USE INTENDED OR CAN BE USED WITHOUT INFRINGING THE PATENT OR COPYRIGHT RIGHTS OF A PERSON.

Buyer agrees to comply with any applicable U.S. export control laws and regulations in regard to any information or data covered by this Article 16. 16.09 Source Codes.

Notwithstanding, Seller recognizes that Buyer may require access to source codes for the programs set out in Schedule 16.09. Buyer shall provide an escrow within ninety (90) days of the Effective Time, to a commercial escrow site, of the source codes for the software set out in Schedule 16.09. In the event that the Seller (i) enters into bankruptcy, either voluntarily or involuntarily; (ii) is dissolved; or (iii) no longer supports the specific source codes or fails to support the specific source code or to offer to support the specific source code in each case, on reasonable commercial terms and conditions, in regard to the above-referenced software, then Buyer shall then be permitted access to said escrowed source codes with a right to make derivative works thereof for Use in the operation of the Refinery. - 100 - 16.10 Transfer of Intellectual Property.
