(c) The Price of chlorine which shall be in effect for the initial calendar quarter, or portion thereof if this Agreement is not effective as of the first day of the initial calendar quarter, shall be calculated as provided in Section 5.1, using the prices in effect pursuant to the National Account Contracts during the calendar quarter immediately preceding the calendar quarter in which this Agreement shall become effective. (d) The Price of caustic soda which shall be in effect for the initial calendar quarter, or portion thereof if this Agreement is not effective as of the first day of the initial calendar quarter, shall be calculated as provided in Section 5.1, using the prices in effect pursuant to the National Account Contracts during the calendar quarter immediately preceding the calendar quarter in which this Agreement shall become effective. (e) Pioneer shall invoice OxyChem for each shipment of chlorine and caustic soda delivered. The prices reflected in the invoice shall be determined as of the date of shipment and shall be the Prices for chlorine and caustic soda designated by OxyChem for the then current calendar quarter. Payment terms for Pioneer's invoice shall be net thirty (30) days from the date of the applicable invoice with OxyChem to pay interest (not to exceed the maximum lawful rate) on any amounts past due in accordance with Pioneer's standard terms and conditions for like customers, a copy of which is attached as Appendix G to this Agreement. Shipments made in a calendar quarter prior to OxyChem's notification of Price pursuant to Section 5.2(a) shall be 7 13 invoiced at the price applicable to shipments during the prior calendar quarter.

(a) Promptly (and in any event within thirty (30) days) after a Party or Parties to be indemnified (whether one or more, the "Indemnified Party") receives notice of any Claim covered by Section 10.1, the Indemnified Party shall, if a Claim in respect thereof is to be made pursuant to Section 10.1, notify the Party from whom indemnification is sought (the "Indemnifying Party") of such Claim; provided, however, that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which it may have to the Indemnified Party pursuant to Section 10.1, except to the extent of any material detriment suffered by the Indemnifying Party as a result of such failure. The amount of each Claim for indemnity, together with a list identifying each separate item of Loss to the extent known, shall be set forth in the Claim notice delivered to the Indemnifying Party. In the event that a Claim arises out of, or results from, Claims of third parties, the Indemnifying Party may at its option undertake the defense thereof by counsel or representatives chosen by it which are reasonably acceptable to the Indemnified Party. The Indemnifying Party shall have the sole right to compromise or settle any such Claim if (i) such settlement or disposition shall impose no material obligation or burden 13 19 whatsoever on the Indemnified Party which is not wholly discharged by the Indemnifying Party and shall provide a full release to the Indemnified Party, and (ii) the Indemnifying Party shall be fully capable of performing its obligations pursuant to such settlement or disposition. Each of the Indemnifying Party and the Indemnified Party shall be entitled to consult with each other, to the extent it reasonably requests, in respect of the defense of such Claim and shall cooperate in the defense of any such Claim, including making its officers, directors, employees and books and records (other than any National Account Contract) available for use in defending against such Claim, and it shall take such commercially reasonable actions within its power which are necessary to preserve any legal defenses to such matters. (b) If the Indemnifying Party, within a reasonable time after notice of any third party Claim, fails to undertake the defense of such Claim, the Indemnified Party will, by notice to the Indemnifying Party of its intent to do so, have the right to undertake the defense of such Claim with counsel or representatives chosen by it which are reasonably acceptable to the Indemnifying Party. The Losses of the Indemnified Party shall include the reasonable costs and expenses incurred in any such defense of a third party's Claim. Notwithstanding the foregoing, the Indemnified Party shall have no right to settle or to compromise any such Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. ARTICLE XI EXCUSE OF PERFORMANCE SECTION 11.1 Excuse of Performance. (a) Performance of any obligation under this Agreement may be suspended by either Party without liability, to the extent that: an Act of God; war; riot; fire; explosion; accident; flood; sabotage; mechanical breakdown; involuntary plant shutdown; governmental laws, regulations or orders; or any other cause (except financial) beyond the reasonable control of such Party, including, without limitation, any refusal or inability of any National Account to perform its obligations under any National Account Contract; or any labor trouble, strike, walkout, lockout or injunction (whether or not such labor event is within the reasonable control of such Party), delays, prevents, restricts, or limits the performance of, this Agreement or the consumption, sale or use of chlorine and caustic soda. The affected Party may invoke this provision by promptly notifying the other party in writing of the nature and estimated duration of the suspension period and shall exercise all reasonable diligence in curing such condition. (b) In the event that either Party exercises its right to suspend performance hereunder, the Term of this Agreement and the obligations of the Parties to purchase and sell chlorine and caustic soda hereunder allocable to such period that performance is suspended shall be extended, to the extent consistent with the National Account Contracts, one day for each day of such suspension provided that the suspension shall not exceed 30 days. In the event that such suspension is greater than 30 days but less than 180 days, this Agreement shall remain in effect with the obligations of the Parties to purchase and sell chlorine or caustic soda hereunder 14 20 suspended and the amount of chlorine and caustic soda which otherwise would have been delivered during the period of suspension deducted from the obligations contained herein to purchase and sell. If any suspension lasts more than 180 days, either Party may terminate this Agreement by providing the other Party written notice of its intent to terminate. ARTICLE XII DEFAULT AND REMEDIES SECTION 12.1 Default and Remedies. (a) In the event that: (i) OxyChem shall fail to pay any invoice in accordance with the terms of this Agreement, or (ii) any Party shall fail, in any material respect, in the due performance or observance by it of any of the terms, covenants or agreements contained in this Agreement, or (iii) any Party shall become or be adjudicated insolvent, bankrupt, or if a receiver or trustee shall be appointed for any Party or its property or a petition for reorganization or arrangement under any bankruptcy or insolvency law shall be approved, or an assignment shall be made for the benefit of creditors of any Party, or any Party shall file a voluntary petition of bankruptcy or shall consent to the appointment of a receiver or trustee, this Agreement shall, in the case of a default under clause (iii), immediately terminate, and in the case of a default under clause (i) or (ii), the non-defaulting Party shall have the right, at its sole discretion, to terminate this Agreement if the defaulting Party shall have failed to (A) cure the default within twenty (20) days of written notice of default, or (B) except in the case of a default under clause (i), diligently pursue the curing of the default, which termination remedy shall be in addition to all of its remedies at law or in equity, including, without limitation, those set forth in Section 12.1(c) to recover damages by reason of such default. In the event of any such termination, all sums owing or to become due and owing by any Party under this Agreement shall become and be immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived by the Parties. (b) In the event that, with respect to any National Account Contract, Pioneer shall fail, in any material respect, in the due performance or observance by it of the performance standards specified in Section 6.1(c), in addition to the remedies provided for in clause (a) above, OxyChem may, upon notice to Pioneer and failure by Pioneer within thirty (30) days following such notice to correct any deficiency or if the matter is not such that it can be corrected in such period, to commence and diligently pursue thereafter steps necessary to correct any deficiency as promptly as possible, remove such National Account Contract from this Agreement, and, upon any such removal, such National Account Contract shall no longer be a National Account Contract subject to the provisions of this Agreement. (c) The Parties agree that the convenants and obligations contained in this Agreement relate to special, unique and extraordinary matters and that a violation of any of the terms hereof would cause irreparable injury in an amount which would be difficult or impossible to estimate or determine and for which any remedy at law would be inadequate. As such, the parties agree that, 15 21 if either Party fails or refuses to fulfill any of its obligations under this Agreement or to make any payment hereunder, then the other Party shall have the remedy of specific performance, which remedy shall be cumulative and nonexclusive and shall be in addition to any other rights and remedies otherwise available at law or in equity and to which such Party might be entitled. SECTION 12.2 Certain Damages Excluded. In no event shall either Party to this Agreement, or its Affiliates, have any liability to the other Party, or its Affiliates, for any (i) loss of business opportunities or for speculative or prospective profits, or (ii) special, indirect, consequential, incidental or punitive damages, provided, however, that in the event of any breach or failure by OxyChem to take and purchase the quantities of chlorine and caustic soda provided for hereunder, Pioneer shall be entitled to recover the difference, if any, between amounts realized from any sale in mitigation of damages resulting from such breach or failure in performance by OxyChem and the amount that would have been realized by Pioneer but for such breach or failure in performance by OxyChem, plus freight costs and throughput charges, if any, actually incurred by Pioneer and which otherwise would have been payable by OxyChem pursuant to the provisions of this Agreement. SECTION 12.3 Duty to Mitigate. Each Party shall take all such reasonable actions as may be necessary to mitigate damages for which such Party may claim damages or indemnification under this Agreement, provided, however, that in no event shall Pioneer be obligated to sell and deliver chlorine or caustic soda committed for but not taken and purchased by OxyChem to other than delivery points east of the Rocky Mountains. ARTICLE XIII MISCELLANEOUS SECTION 13.1 Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, by operation of law or otherwise (other than as a result of any merger or consolidation), by any Party without the prior express written consent of the other Party; provided, however, that, notwithstanding the foregoing, (i), in connection with the sale of the Tacoma Plant as a whole, or any sale of the properties and assets of any Party substantially as an entirety, to any Person, the Party making such sale may assign this Agreement, or its rights hereunder, to such Person, (ii) any Party may assign this Agreement, or its rights hereunder, to any Affiliate of such Party, and (iii) Pioneer shall have the right to collaterally assign its rights under this Agreement to any bank, financial institution or other lender (or any such entity acting as an indenture trustee on behalf of any Person) that provides financing in connection with (x) the transactions contemplated by the Asset Purchase Agreement or any Related Agreement (including any renewal, extension or rearrangement of such financing) or (y) working capital financing for Facility Operations, provided, however, that no such collateral assignment shall release, discharge or otherwise excuse Pioneer from the performance of its obligations under this Agreement; provided, further, that (A), in the case of any assignment referred to in clause (i) or (ii) of this Section 13.1, prior to any such 16 22 assignment, the Person to which such assignment shall be made shall expressly assume, by an instrument in writing reasonably satisfactory to OxyChem or Pioneer, as the case may be, executed and delivered to OxyChem or Pioneer, as the case may be, the performance and observance of every obligation, covenant and agreement in this Agreement on the part of the Party making such assignment to be performed or observed, and (B) no such assignment shall have the effect of releasing such Party or any other Person (including any such additional Party) from its obligations, covenants or agreements under this Agreement.

This Agreement constitutes the entire agreement of the Parties with respect to the subject matter hereof and supersedes all prior understandings and agreements with respect thereto. This Agreement may be amended, and any provision hereof waived, but only in writing signed by the Party against whom such amendment or waiver is sought to be enforced. No waiver by any Party of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any such occurrence. Neither the failure nor any delay by any Party in exercising any right, power or privilege under 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 further or other exercise of such right, power or privilege or the exercise of any other right, power or privilege.
