(e) If a Party in good faith disputes the amount of any Monthly Net Payment that is owed to the other Party, it shall pay the undisputed portion of such payment owed to the other Party by the due date and inform the other Party in writing why it disagrees with the balance of the Monthly Net Payment. The Parties shall cooperate in resolving the dispute expeditiously. If the Parties mutually agree as to some or all of the disputed amount, the Party owing such disputed amount shall pay such amount, with interest from the original due date, within two (2) Business Days from the date of their agreement.

(d) Either Party fails to perform any obligation to the other under this Agreement (other than an Event of Default described in clauses (a), (b) or (c) above), which is not cured to the satisfaction of the other Party (in its sole discretion) within ten (10) Business Days from the date that such Party receives written notice that corrective action is needed. (e) Either Party breaches any representation, covenant (except in respect of Section 8.2) or warranty made or repeated or deemed to have been made or repeated by the Party in any material respect, or any representation proves to have been incorrect or misleading in any material respect when made or repeated or deemed to have been made or repeated under this Agreement. (f) Either Party defaults under any other agreement or transaction now existing or hereafter entered into between MSCG and Premcor in any material respect (excluding any agreement or transaction that constitutes the obligation, whether present or future, contingent or otherwise, as principal or surety or otherwise, in respect of borrowed money and any securities repurchase or reverse repurchase agreement or similar transaction between the Parties), which is not cured within the applicable time period, if any. (g) Either Party: (i) is dissolved (other than pursuant to a consolidation, amalgamation or merger); (ii) becomes insolvent or is generally unable to pay its debts or fails or admits in writing its inability generally to pay its debts as they become due; 16 (iii) makes a general assignment, arrangement or composition with or for the benefit of its creditors; (iv) institutes or has instituted against it a proceeding seeking a judgment of insolvency or bankruptcy or any other relief under any bankruptcy or insolvency law or other similar law affecting creditors' rights, or a petition is presented for its winding-up or liquidation, and, in the case of any such proceeding or petition instituted or presented against it, such proceeding or petition (A) results in a judgment of insolvency or bankruptcy or the entry of an order for relief or the making of an order for its winding-up or liquidation or (B) is not dismissed, discharged, stayed or restrained within thirty (30) days; (v) has a resolution passed for its winding-up, official management or liquidation (other than pursuant to a consolidation, amalgamation or merger); (vi) seeks or becomes subject to the appointment of an administrator, provisional liquidator, conservator, receiver, trustee, custodian or other similar official for all or substantially all its assets; (vii) has a secured party take possession of all or substantially all its assets or has a distress, execution, attachment, sequestration or other legal process levied, enforced or sued on against all or substantially all its assets and such secured party maintains possession, or any such process is not dismissed, discharged, stayed or restrained; (viii) causes or is subject to any event with respect to it which, under the applicable laws of any jurisdiction, has an analogous effect to any of the events specified in clauses (i) to (vii) inclusive; or (ix) takes any action in furtherance of, or indicating its consent to, approval of, or acquiescence in, any of the foregoing acts.

Notwithstanding any other provision of this Agreement, upon the occurrence of an Event of Default with respect to either Party (referred to as the "Defaulting Party"), the other Party (the "Performing Party") shall in its sole discretion and upon one (1) Business Day's written notice to the Defaulting Party, be entitled to take the following actions: (a) If Premcor is the Defaulting Party, MSCG may declare an accelerated Sale Date, which date shall be at its sole discretion, and (i) demand that Premcor repurchase the Line Fill Oil on such date, or if it refuses to do so in a timely manner, (ii) withdraw the Purchase Date Volume of Line Fill Oil from the Pipeline Systems and terminate this Agreement. (b) If MSCG is the Defaulting Party, Premcor may declare an accelerated Sale Date, which date shall be at its sole discretion, provided, however, that Premcor complies with all of the payment terms of this Agreement. (c) In the event of an accelerated Sale Date, the price set forth in Section 5.2 shall be adjusted to reflect the (i) market value of the Line Fill Oil on the accelerated Sale Date, which shall be determined based on the front line NYMEX settlement price per barrel for WTI posted on such date, minus (ii) the original per Barrel differential agreed upon pursuant to Section 5.2(b), (iii) plus or minus the actual spread differential between the September 2003 NYMEX settlement price per barrel for WTI and the front line NYMEX settlement price on the accelerated Sale Date, or such other date as MSCG may reasonably determine in its sole discretion. 11.3 Close Out of Other Contracts Between the Parties. (a) In addition to the foregoing remedies, the Performing Party shall, in its sole discretion and upon one (1) Business Day's written notice to the Defaulting Party, be entitled to immediately liquidate any or all any other outstanding contracts between the Parties ("Contracts") as of a designated date ("Early Termination Date") by closing out each such Contract at its market value, as determined by the Performing Party in a commercially reasonable manner as of or close to the Early Termination Date, and calculating an amount equal to the difference, if any, between the market value and the value specified in such Contract ("Settlement Payment"). The Performing Party then shall be entitled to set off, net or aggregate (i) all Settlement Payments so determined and payable by each Party to the other, (ii) all damages, losses and expenses incurred by the Performing Party as a result of termination and liquidation of Contracts, including reasonable attorneys' fees, court costs, collection costs, interest charges and other disbursements and any damages, losses and expenses incurred in obtaining, maintaining or liquidating commercially reasonable hedges or related trading positions relating to the Contracts that are being liquidated, all as determined in a commercially reasonable manner by the Performing Party, (iii) all margin or collateral held by either Party to 18 secure the obligations of the other Party, and (iv) any other amounts one Party owes the other under a Contract (which unpaid amounts shall be deemed to be held by a Party as margin to secure the other Party's obligations from time to time incurred), whereupon all such amounts shall be aggregated or netted to a single liquidated amount ("Termination Payment"). (b) On the Early Termination Date or as soon as reasonably practicable thereafter, the Performing Party shall provide the Defaulting Party with a statement showing, in reasonable detail, the calculation of the Termination Payment. Any Termination Payment due to the Defaulting Party shall be paid concurrently with the delivery of statement contemplated by this paragraph. If the Defaulting Party owes the Termination Payment to the Performing Party, the Defaulting Party shall pay the Termination Payment on the first Business Day after it receives the statement. 11.4 The Performing Party's rights under this Article 12 are in addition to, and not in limitation or exclusion of, any other rights that it may have (whether by agreement, operation of law or otherwise), including any rights and remedies under the UCC. The Performing Party may enforce any of its remedies under this Agreement successively or concurrently at its option. No delay or failure on the part of a Performing Party to exercise any right or remedy to which it may become entitled on account of an Event of Default shall constitute an abandonment of any such right, and the Performing Party shall be entitled to exercise such right or remedy at any time during the continuance of an Event of Default. All of the remedies and other provisions of this Article 12 shall be without prejudice and in addition to any right of setoff, recoupment, combination of accounts, Lien or other right to which any Party is at any time otherwise entitled (whether by operation of law, in equity, under contract or otherwise). 11.5 The Defaulting Party shall indemnify and hold harmless the Performing Party for all Liabilities incurred as a result of the Default or in the exercise of any remedies under this Article 12, including any damages, losses and expenses incurred in obtaining, maintaining or liquidating commercially reasonable hedges relating to the Line Fill and Buy/Sell Oil to be sold hereunder, all as determined in a commercially reasonable manner by the Performing Party. ARTICLE 12 INDEMNIFICATION 12.1 To the fullest extent permitted by applicable law, Premcor shall defend, indemnify and hold harmless MSCG, its Affiliates, and their directors, officers, employees, representatives, agents and contractors, for and against (i) any Taxes imposed on the Buy/Sell Oil or the Line Fill Oil, and all penalties or interest thereon, and (ii) any Liabilities, including those related to injury, disease, or death of any person or damage to or loss of any property, that directly or indirectly arise out of (X) any adverse claims or Liens to the Line Fill Oil or Buy/Sell Oil that are asserted by Premcor, its Affiliates, employees, agents or creditors or any other Person claiming throughout or on behalf of Premcor, (Y) Premcor's breach of any representations, warranties or covenants made herein, or (Z) Premcor's breach of any of its obligations under this Agreement. 19 12.2 MSCG agrees to notify Premcor as soon as practicable after receiving notice of any suit brought against it within the indemnities of this Agreement, shall furnish Premcor with complete details within its knowledge and shall render all reasonable assistance requested by Premcor in the defense. MSCG shall have the right but not the duty to participate with counsel of its own selection, at Premcor's expense, in the defense and settlement of any claim or in any proceeding against MSCG without relieving Premcor of any obligations hereunder. If Premcor fails to assume the defense promptly after a claim is brought against MSCG, MSCG may conduct such defense, with all reasonable costs, including attorneys' fees, at Premcor's expense. Premcor is not authorized to compromise or settle any claim against MSCG without MSCG's approval. ARTICLE 13 LIMITATION ON DAMAGES Except in respect of claims made by third parties for which Premcor must indemnify MSCG pursuant to Article 13, the Parties' liability for damages is limited to direct, actual damages only and neither Party shall be liable for special, consequential, incidental, punitive, exemplary or indirect damages, in tort, contract or otherwise, of any kind, arising out of or in any way connected with the performance, the suspension of performance, the failure to perform, or the termination of this Agreement. Each Party acknowledges the duty to mitigate damages hereunder. ARTICLE 14 CONFIDENTIALITY 14.1 The Parties agree that the specific terms and conditions of this Agreement and any Buy/Sell Transaction are confidential and shall not disclose them to any third party, except (i) as may be required by court order, Laws and Regulations or a Governmental Authority, or (ii) to such Party's or its Affiliates' employees, auditors, consultants, banks, financial advisors and legal advisors. The confidentiality obligations under this Agreement shall survive termination of this Agreement for a period of two (2) years following termination. 14.2 In the case of disclosure covered by subclause (i) of Section 15.1 and if the disclosing Party's counsel advises that it is permissible to do so, the disclosing Party shall notify the other Party in writing of any proceeding of which it is aware which may result in disclosure, and use reasonable efforts to prevent or limit such disclosure. The Parties shall be entitled to all remedies available at law, or in equity, to enforce or seek relief in connection with the confidentiality obligations contained herein. ARTICLE 15 GOVERNING LAW 15.1 THIS AGREEMENT SHALL BE GOVERNED BY, CONSTRUED AND ENFORCED UNDER THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ITS CONFLICTS OF LAWS PRINCIPLES. 15.2 EACH OF THE PARTIES HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY FEDERAL COURT OF COMPETENT JURISDICTION SITUATED IN THE BOROUGH 20 OF MANHATTAN, NEW YORK, OR, IF ANY FEDERAL COURT DECLINES TO EXERCISE OR DOES NOT HAVE JURISDICTION, IN ANY NEW YORK STATE COURT IN THE BOROUGH OF MANHATTAN (WITHOUT RECOURSE TO ARBITRATION UNLESS BOTH PARTIES AGREE IN WRITING), AND TO SERVICE OF PROCESS BY CERTIFIED MAIL, DELIVERED TO THE PARTY AT THE ADDRESS INDICATED ABOVE. EACH PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION TO PERSONAL JURISDICTION, WHETHER ON GROUNDS OF VENUE, RESIDENCE OR DOMICILE. 15.3 EACH PARTY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDINGS RELATING TO THIS AGREEMENT. ARTICLE 16 ASSIGNMENT 16.1 This Agreement shall inure to the benefit of and be binding upon the Parties hereto, their respective successors and permitted assigns. 16.2 Neither Party shall assign this Agreement or its rights or interests hereunder in whole or in part, or delegate its obligations hereunder in whole or in part, without the express written consent of the other Party except in the case of assignment to Affiliate if (i) such Affiliate assumes in writing all of the obligations of the assignor and (ii) the assignor provides the other Party with evidence of the Affiliate's financial responsibility at least equal to that of the assignor. If written consent is given for any assignment, the assignor shall remain jointly and severally liable with the assignee for the full performance of the assignor's obligations under this Agreement, unless the Parties otherwise agree in writing. 16.3 Any attempted assignment in violation of this Article shall be null and void ab initio and the non-assigning Party shall have the right, without prejudice to any other rights or remedies it may have hereunder or otherwise, to terminate this Agreement effective immediately upon notice to the Party attempting such assignment. ARTICLE 17 NOTICES 17.1 All invoices, notices, requests and other communications given pursuant to this Agreement shall be in writing and sent by facsimile, electronic mail or overnight courier.
