UNDERTAKING AGREEMENT dated as of December 17, 2003 by EQUISTAR CHEMICALS, LP in favor of the Purchasers, as defined in the Receivables Purchase Agreement referred to below, and Citicorp USA, Inc. (“CUSA”), as administrative agent (the “Agent”) thereunder.

RECITALS

Equistar Chemicals, LP, a Delaware limited partnership (“Equistar”), owns, directly or indirectly, all of the issued and outstanding membership interests of Equistar Receivables II, LLC, a Delaware limited liability company (the “Seller”), and, to the extent there are Originators (as defined in the Receivables Purchase Agreement) other than Equistar, will own all of the issued and outstanding equity interests in each of such other Originators.

The Seller, as buyer, and Equistar and the other Originators (if any), as sellers (and, in the case of Equistar, as buyer’s servicer), have entered into a Receivables Sale Agreement dated as of the date hereof (the “Receivables Sale Agreement”), pursuant to which Equistar and such other Originators sell and transfer all Seller Receivables (as defined in the Receivables Sale Agreement) originated by such Originator, together with certain related assets (including collections), to the Seller.

The Seller and Equistar, as initial Servicer, have entered into a Receivables Purchase Agreement dated as of the date hereof (the “Receivables Purchase Agreement”) with the banks and other financial institutions listed on the signature pages thereof, CUSA and Bank of America, as co-asset agents, and CUSA, as Agent. Pursuant to the Receivables Purchase Agreement, the Seller may sell to one or more of the Purchasers, as the case may be, undivided percentage ownership interests in Receivables and related assets that were acquired by the Seller from the Originators.

The Agent and the Purchasers have requested that Equistar provide, and Equistar is willing to provide, certain additional assurances, as set forth herein, as to the ability of Equistar to perform its obligations, as Originator and as Servicer, under the Transaction Documents (as defined in the Receivables Purchase Agreement) and as to the ability of any other Originator to perform its obligations as Originator under the Receivables Sale Agreement, and it is therefore a condition precedent to the effectiveness of the Receivables Purchase Agreement that Equistar shall have executed and delivered this Agreement.

NOW, THEREFORE, in consideration of the premises, and the substantial direct and indirect benefits to Equistar from the financing arrangements contemplated by the Receivables Purchase Agreement and the Receivables Sale Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledge, Equistar hereby agrees as follows:

In the event that the Servicer (so long as any Affiliate of Equistar is the Servicer) or any of the other Originators shall fail in any manner whatsoever to perform or observe any of its Obligations when the same shall be required to be performed or observed, then Equistar shall itself duly and punctually perform or observe, or cause to be duly and punctually performed and observed, such Obligation, and it shall not be a condition to the accrual of the obligation of Equistar hereunder to perform or observe any Obligation (or to cause the same to be performed or observed) that any Indemnified Party shall have first made any request of or demand upon or given any notice to the Servicer (so long as any Affiliate of Equistar is the Servicer) or any of the other Originators or any of their successors or assigns, or have instituted any action or proceeding against the Servicer (whether or not any Affiliate of Equistar is the Servicer) or any of the other Originators or any of their successors or assigns in respect thereof.

Section 5.02. Obligations Absolute. Equistar undertakes and agrees that the Obligations will be paid and performed strictly in accordance with the terms of the Transaction Documents and each other document delivered in connection therewith, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Indemnified Party with respect thereto. The obligations of Equistar under this Article 5 are independent of the Obligations, and a separate action or actions may be brought and prosecuted against Equistar to enforce the obligations under this Article 5, irrespective of whether any action is brought against the Servicer (if any Affiliate of Equistar is the Servicer) or any of the other Originators or whether the Servicer (if any Affiliate of Equistar is the Servicer) or any of the other Originators are joined in any such action or actions. The liability of Equistar under this Article 5 shall be irrevocable, absolute and unconditional irrespective of, and to the extent permitted by law, Equistar hereby irrevocably waives any defenses (except for any defenses arising or accruing as a result of the gross negligence or willful misconduct of any of the Indemnified Parties) it may now or hereafter have in any way relating to, any or all of the following:

(e) any change, restructuring or termination of the structure or existence of the Servicer (whether or not any Affiliate of Equistar is the Servicer) or any of the other Originators;

(f) any failure of any Indemnified Party to disclose to Equistar any information relating to the financial condition, operations, properties or prospects of any of the other Originators now or in the future known to such Indemnified Party (Equistar waiving any duty on the part of such Indemnified Party to disclose such information);

(g) any impossibility or impracticality of performance, illegality, any act of any government, or any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Indemnified Party that might constitute a defense available to, or a discharge of, the Servicer (whether or not any Affiliate of Equistar is the Servicer) or any of the Originators or a guarantor of the Obligations; or

(h) any other circumstance, event or happening whatsoever, whether foreseen or unforeseen and whether similar or dissimilar to anything referred to above in this Section 5.02.

The provisions of this Article 5 shall continue to be effective or be reinstated, as the case may be, if any time (x) any payment in connection with any of the Obligations is rescinded or must otherwise be returned by any Indemnified Party, or (y) any performance or observance of any Obligation is rescinded or otherwise invalidated, upon the insolvency, bankruptcy or reorganization of the Servicer (if any Affiliate of Equistar is the Servicer) or any of the other Originators or otherwise, all as though payment had not been made or as though such Obligation had not been performed or observed.

(b) Equistar hereby waives any right to revoke this Agreement, and acknowledges that this Agreement is continuing in nature and applies to all Obligations whether existing now or in the future.

Section 5.04. Subrogation. Equistar shall not exercise or assert any rights that it may now have or hereafter acquire against the Servicer (to the extent Equistar is not the Servicer), or any of the other Originators that arise from the existence, payment, performance or enforcement of Equistar’s obligations under this Agreement or any other Transaction Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification or any right to participate in any claim or remedy of any Indemnified Party against such Servicer or any of the other Originators or any asset or collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from such Servicer or any of the other Originators, directly or indirectly, in cash or other property or by setoff or in any other manner, payment or security on account of such claim, remedy or right, unless and until all amounts in connection with the Obligations and all amounts payable under this Agreement shall have been paid in full and all other amounts payable to the Indemnified Parties under the Transaction Documents shall have been paid in full.
