Demand Registration. In addition to preparing the Lyondell Registration Statement pursuant to the provisions of Section 2 hereof, Lyondell hereby agrees to at any time prior to May 1, 2004: (a) Upon written notice from a Holder of Registrable Securities in the manner set forth in Section 13(g) hereof requesting that Lyondell effect the registration under the Act of any or all of the Registrable Securities held by such Holder, which notice shall specify the intended method or methods of disposition of such Registrable Securities, Lyondell will use its best efforts to effect (at the earliest possible date) the registration under the Act of such Registrable Securities for disposition in accordance with the intended method or methods of disposition stated in such request; provided, however, that in Lyondell's sole discretion it may refuse to register an offering on a delayed or continuous basis pursuant to Rule 415 (or any successor rule to similar effect) promulgated under the Act (a "Rule 415 Offering")), provided, further, that: (i) if, prior to receipt of a registration request pursuant to this Section 3(a), (A) Lyondell has publicly announced a proposed financing, acquisition or other transaction and (B) Lyondell's Board of Directors makes a good faith determination that to proceed with the requested registration would materially and adversely affect such proposed transaction, then Lyondell shall have the right to postpone such requested registration for the period of time its Board of Directors determines in good faith, but in no event longer than one year from the date of the request, is required to implement such proposed transaction; (ii) if, while a registration request pursuant to this Section 3(a) is pending, the Board of Directors of Lyondell determines in good faith (A) that Lyondell then is unable to comply with the applicable SEC requirements for reasons beyond Lyondell's control or (B) that Lyondell is precluded from proceeding with the requested registration pursuant to existing "hold back" agreements, Lyondell shall not be required to effect a registration pursuant to this Section 3(a) until the earlier of (1) the date that Lyondell is able to comply with SEC requirements or the hold back agreement expires, or (2) 120 days after receipt of the registration request; (iii) if, upon receipt of a registration request pursuant to this Section 3(a), (A) Lyondell is actively considering a bona fide financing, acquisition or other transaction material to Lyondell with the full knowledge and concurrence of its Board of Directors, and (B) the Board of Directors of Lyondell determines in good faith that the filing of a registration statement would require the disclosure of material information which Lyondell has a bona fide business purpose for preserving as confidential and, as a result, Lyondell is unable to comply with SEC requirements without making such disclosure, then Lyondell shall not be required to effect a registration pursuant to this Section 3(a) prior to (X) if Lyondell has not made a public disclosure regarding such proposed transaction within 120 days of receipt of the request, the expiration of such 120-day period, or (Y) if Lyondell makes a public disclosure regarding such proposed transaction within 120 days of receipt of the request, then the expiration of such period of time, as may be determined in good faith by Lyondell's Board of Directors, that is required to implement such proposed transaction, which shall in no event exceed one year from the date of receipt of the request; and (iv) ARCO, together with its transferees, shall have the right to exercise registration rights pursuant to this Section 3 an aggregate of three (3) times; provided, however, that such registration rights may not be implemented more than once during each 12-month period. (b) Notwithstanding any other provision of this Agreement to the contrary, a registration requested by a Holder of Registrable Securities pursuant to this Section 3 shall not be deemed to have been effected (and, therefore, not requested for purposes of subsection 3(a)), (i) unless it has become effective, (ii) if after it has become effective such registration is interfered with by any 3 stop order, injunction or other order or requirement of the SEC or other governmental agency or court for any reason other than a misrepresentation or an omission by such Holder and, as a result thereof, the Registrable Securities requested to be registered cannot be completely distributed in accordance with the plan of distribution set forth in the related registration statement or (iii) if the conditions to closing specified in the purchase agreement or underwriting agreement entered into in connection with such registration are not satisfied or waived other than by reason of some act or omission by such Holder of Registrable Securities. 4. Piggyback Registration. If prior to May 1, 2004, Lyondell at any time proposes to register any of its Common Stock or any other of its Common Stock or securities convertible into Common Stock (collectively, "Other Securities") under the Act (other than a registration on Form S-4 or S-8 or any successor forms of similar effect), whether or not for sale for its own account, in a manner which would permit registration of Registrable Securities for sale for cash to the public under the Act, it will each such time give prompt written notice to each Holder of Registrable Securities of its intention to do so and of the rights of such Holder under this Section 4, at least 30 days prior to the anticipated filing date of the registration statement relating to such registration. Such notice shall offer each such Holder the opportunity to include in such registration statement such number of Registrable Securities as such Holder may request. Upon the written request of any such Holder made within 10 days after the receipt of Lyondell's notice (which request shall specify the number of Registrable Securities intended to be disposed of and the intended method of disposition thereof), Lyondell will use its best efforts to effect, in connection with the registration of the Other Securities, the registration under the Act of all Registrable Securities which Lyondell has been so requested to register, to the extent required to permit the disposition (in accordance with such intended methods thereof) of the Registrable Securities so requested to be registered, provided that: (a) if, at any time after giving such written notice of its intention to register any Other Securities and prior to the effective date of the registration statement filed in connection with such registration, Lyondell shall determine for any reason not to register the Other Securities, Lyondell may, at its election, give written notice of such determination to such Holders and thereupon Lyondell shall be relieved of its obligation to register such Registrable Securities in connection with the registration of such Other Securities, without prejudice, however, to the rights of the Holders of Registrable Securities immediately to request that such registration be effected as a registration under Section 3 hereof (in the event that Lyondell shall so determine not to so register the Other Securities, each of Lyondell and each Holder shall be responsible for the respective Registration Expenses incurred by it in connection with such registration); (b) if the registration referred to in the first sentence of this Section 4 is to be an underwritten primary registration on behalf of Lyondell, and a nationally recognized investment banking firm selected by Lyondell advises Lyondell in writing that, in such firm's opinion, such offering would be materially and adversely affected by the inclusion therein of the Registrable Securities requested to be included therein, Lyondell shall use its best efforts to include in such registration: (i) first, all securities Lyondell proposes to sell for its own account ("Lyondell Securities"), (ii) second, up to (A) the full number of Registrable Securities held by ARCO and requested to be included in such registration by ARCO ("ARCO Securities"); and (B) the full number of securities of Lyondell (other than Registrable Securities) held by persons (other than current or former Lyondell officers, directors or employees) to whom Lyondell has granted registration rights ("Other Holders") in excess of the number or dollar amount of securities Lyondell proposes to sell which, in the good faith opinion of such underwriter(s), can be so sold without so materially and adversely affecting such offering, allocated, if necessary, pro rata by taking into consideration (x) the ARCO Securities and (y) the full number of securities held by Other Holders and requested to be included in such registration by the Other Holders, and (iii) third, up to the full number of Registrable Securities (other than ARCO Securities) in excess of the number or dollar amount of Lyondell Securities, ARCO Securities and securities of Other Holders which, in the good faith opinion of such underwriter(s) can be so sold without materially and adversely affecting such offering (and, if less than the full number of such Registrable Securities, 4 allocated pro rata among the Holders of such Registrable Securities (other than ARCO Securities) on the basis of the number of securities requested to be included therein by each such Holder); (c) if the registration referred to in the first sentence of this Section 4 is to be an underwritten secondary registration on behalf of Other Holders, and the managing underwriter(s) advise Lyondell in writing that in their good faith opinion such offering would be materially and adversely affected by the inclusion therein of the Registrable Securities requested to be included therein, Lyondell shall use its best efforts to include in such registration: (i) first, up to the full number of securities held by Other Holders and requested to be included in such registration by the Other Holders, (ii) second, up to the full number of ARCO Securities requested to be included in such registration by ARCO in excess of the number or dollar amount of securities of Other Holders which, in the good faith opinion of such underwriter(s), can be so sold without materially and adversely affecting such offering and (iii) third, up to the full number of Registrable Securities (other than ARCO Securities) in excess of the number or dollar amount of the securities of Other Holders and ARCO Securities which, in the good faith opinion of such underwriter(s) can be so sold without materially and adversely affecting such offering (and, if less than the full number of such Registrable Securities, allocated pro rata among the Holders of such Registrable Securities (other than ARCO Securities) on the basis of the number of such securities requested to be included therein by each such Holder); (d) Lyondell shall not be required to effect any registration of Registrable Securities under this Section 4 incidental to the registration of any of its securities in connection with mergers, acquisitions, exchange offers, subscription offers, dividend reinvestment plans or stock option or other executive or employee benefit or compensation plans; and (e) no registration of Registrable Securities effected under this Section 4 shall relieve Lyondell of its obligation to effect a registration of Registrable Securities pursuant to Section 3 hereof; provided, however, that if Registrable Securities are not included in a registration as a result of the application of the provisions of Sections 4(b) or 4(c) hereof, the Holders of such Registrable Securities may not request that such registration be effected as a registration under Section 3 hereof until after the registration from which such Registrable Securities were excluded has been completed or abandoned. 5. Expenses. ARCO (and any Holder other than ARCO, in the case of a registration pursuant to Section 3 hereof) hereby agrees to pay all of the Registration Expenses in respect of a registration effected pursuant to Sections 2 and 3 hereof, including, without limiting the generality of the foregoing, ARCO agrees that in connection with the registration effected pursuant to Section 2 hereof, ARCO shall reimburse Lyondell for all out-of- pocket costs incurred by Lyondell in connection with the negotiation and review of this Registration Rights Agreement, as well as the review of the proposed registration and related transactions by Lyondell's Audit Committee, together with the costs incurred in retaining outside legal counsel for the Audit Committee. In the case of a registration pursuant to the provisions of Section 4 hereof, each of ARCO, any Holder other than ARCO, any Other Holders and Lyondell agrees to pay its pro rata portion of Registration Expenses with respect to a particular offering, such pro rata portion to be equal to the total amount of such Registration Expenses multiplied by a fraction, the numerator of which is the number of shares sold in such offering by such party and the denominator of which is the total number of shares sold in such offering. 6. Registration and Qualification. If and whenever Lyondell is required to use its best efforts to effect the registration of any Registrable Securities under the Act as provided in Sections 3 or 4 hereof, Lyondell will as promptly as is practicable: (a) prepare, file and use its best efforts to cause to become effective a registration statement under the Act relating to the Registrable Securities to be offered;

provided, that such nine month period shall be extended for such number of days that equals the number of days elapsing from (x) the date the written notice contemplated by Section 6(g) hereof is given by Lyondell to (y) the date on which Lyondell delivers to the Holders of Registrable Securities the supplement or amendment contemplated by Section 6(g) hereof;

(b) In the event that ARCO owns more than 20 percent of the issued and outstanding Lyondell Common Stock, and ARCO or any Holder has requested registration of some or all of its Lyondell Common Stock pursuant to Section 3 hereof, ARCO agrees with Lyondell that in the event the Underwriters request Lyondell to agree to a contribution provision, ARCO will not expect nor can ARCO or any Holder require Lyondell to agree to any such contribution provision. (c) In the event that ARCO owns less than 20 percent of the issued and outstanding Lyondell Common Stock, and has requested registration of some or all of its Lyondell Common Stock pursuant to Sections 3 or 4 hereof, Lyondell will indemnify and hold harmless ARCO or any Holder against any losses, claims, damages or liabilities, joint or several, to which ARCO or any Holder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Lyondell Documents or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse ARCO or any Holder for any legal or other expenses reasonably incurred by ARCO or any Holder in connection with investigating or defending any such action or claim; provided, however, that Lyondell shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Lyondell Documents or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to Lyondell by ARCO or any Holder expressly for use therein; and provided, further, that Lyondell shall not be liable to ARCO or any Holder under the indemnity agreement in this subsection (c) with respect to any Lyondell Documents to the extent that any such loss, claim, damage or liability of ARCO or any Holder results from the fact that ARCO or any Holder sold Common Stock to a person to whom there was not sent or given, at or prior to the written confirmation of such sale, a copy of the Lyondell final prospectus, if Lyondell has previously furnished copies thereof to such Underwriter. (d) Such Holder will indemnify and hold harmless Lyondell and each Underwriter against any losses, claims, damages or liabilities, joint or several, to which Lyondell and each Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of such Holder's Registrable Securities) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact made in any Lyondell Document in reliance upon and in conformity with written information furnished to Lyondell by such Holder expressly for use therein; and will reimburse each Underwriter and Lyondell for any legal or other expenses reasonably incurred by each Underwriter and Lyondell in connection with investigating or defending any such action or claim. (e) Each Underwriter will indemnify and hold harmless such Holder and Lyondell against any losses, claims, damages or liabilities to which such Holder and Lyondell may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Lyondell Documents, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the 9 statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Lyondell Documents in reliance upon and in conformity with written information furnished to such Holder or Lyondell by such Underwriter expressly for use therein; and will reimburse each such Holder and Lyondell for any legal or other expenses reasonably incurred by such Holder and Lyondell in connection with investigating or defending any such action or claim. (f) Promptly after receipt by an indemnified party under subsection (a), (c), (d) or (e) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable out-of-pocket costs of investigation relating thereto. If the indemnifying party is either such Holder or Lyondell, and the Underwriters are the indemnified party, such Holder or Lyondell, as the case may be, shall not be liable for the expenses of more than one separate counsel for the Underwriters (except for expenses of local counsel, if necessary), which counsel shall be approved by the Underwriters. (g) In the case of a registration pursuant to Section 4 hereof, if the indemnification provided for in this Section is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (c), (d) or (e) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by such Holder, Other Holders, and Lyondell, as applicable, on the one hand, and the Underwriters on the other from the offering of the Common Stock. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (f) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such Holder, Other Holders or Lyondell, as applicable, on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by such Holder, Other Holders or Lyondell, as applicable, on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of the Common Stock purchased under this Agreement (before deducting expenses) received by such Holder, Other Holders or by Lyondell, as applicable, bear to the total underwriting discounts and commissions received by the Underwriters with respect to the Common Stock purchased under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Holder, Other Holders, Lyondell or the Underwriters and the party's relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Such Holder, Other Holders, Lyondell and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection 10 (g) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (g). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (g) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (g), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Common Stock underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (g) to contribute are several in proportion to their respective underwriting obligations and not joint. (h) The obligations of Lyondell under this Section 9 shall be in addition to any liability which Lyondell may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act. 10. Rule 144. Lyondell shall take such measures and file such information, documents and reports as shall be required by the SEC as a condition to the availability of Rule 144 (or any successor provision). 11. Transfer of Registration Rights. (a) ARCO may transfer all or any portion of its rights under this Agreement to any transferee (each, a "transferee") of an amount of Registrable Securities owned by ARCO exceeding 1 percent of the outstanding class of such Securities at the time of transfer. Any transfer of registration rights pursuant to this Section shall be effective upon receipt by Lyondell of written notice from ARCO stating the name and address of any transferee and identifying the amount of Registrable Securities with respect to which the rights under this Agreement are being transferred and the nature of the rights so transferred. In connection with any such transfer, the term "ARCO" as used in this Agreement (other than in this Section 11, Section 4(b)(i)(2) and Section 1(b)) shall, where appropriate to assign the rights and obligations of ARCO hereunder to such direct transferee, be deemed to refer to the transferee holder of such Registrable Securities. ARCO and such transferees may exercise the registration rights hereunder in such proportion as they shall agree among themselves; provided, that in no event shall Lyondell be required to effect more than an aggregate of three (3) registrations pursuant to Section 3 of this Agreement and each such registration shall be at the request of one or more Holders. (b) After any such transfer, ARCO shall retain its rights under this Agreement with respect to all other Registrable Securities owned by ARCO. (c) Upon the request of ARCO, Lyondell shall execute a Registration Rights Agreement with such transferee or a proposed transferee substantially similar to this Agreement, and any demand registrations granted to such transferee shall reduce the then remaining number of demand registrations to which ARCO is entitled under Section 3(a) hereof. 12. Payment of Certain Defense Costs. Subject to the provisions of this Section 12, ARCO hereby agrees, in the event of an actual or threatened legal proceeding arising in connection with a registration effected pursuant to Section 2 or 3 hereof, to pay all Defense Costs (as defined herein) as they are incurred by or on behalf of (i) Lyondell and each officer and director of Lyondell and each person, if any, who controls Lyondell (other than ARCO) within the meaning of the Act, and (ii) the underwriters, if any, in connection with any such registration, and each person, if any, who controls any such 11 underwriter within the meaning of the Act; provided, however, that the persons described in clauses (i) and (ii) shall hereinafter be referred to collectively as the "Designated Defendants;" and, provided, further, that in the event (A) that the applicable underwriting agreement (including the Underwriting Agreement) provides that Lyondell shall reimburse the Underwriter(s) for any Defense Costs incurred by such Underwriter(s) and (B) that such Underwriters request Lyondell to make any such payments, ARCO, in accordance with the provisions of this Section 12, either shall pay such Defense Costs to such Underwriter(s) or contemporaneously shall reimburse Lyondell for any such payments Lyondell makes to such Underwriter(s), in either case, within such time periods as may be necessary to prevent Lyondell from defaulting with respect to any obligation to reimburse the Underwriter(s) for such expenses under the applicable provision of the underwriting agreement. "Defense Costs" shall mean the following costs and expenses incurred by the Designated Defendants: (A) all reasonable and customary fees and expenses of counsel for each of the Designated Defendants; (B) all reasonable and customary fees and expenses of local counsel for the Designated Defendants; (C) all other reasonable and customary out-of-pocket costs incurred by the Designated Defendants as a result of an actual or threatened legal proceeding arising in connection with this Registration Rights Agreement or a registration effected pursuant to Section 2 or 3 hereof including without limitation expenses incurred for retaining the services of experts and consultants and in responding to discovery requests. Lyondell hereby agrees, in the event of a legal proceeding arising in connection with a registration effected pursuant to Section 2 or 3 hereof, that, as between Lyondell and ARCO, ARCO shall have the lead in managing the defense of the proceeding. Lyondell further agrees that it will reimburse ARCO for its "applicable share" of Defense Costs in the event that a court of competent jurisdiction makes a final determination, after the exhaustion of all appeals, that Lyondell acted with an intent to defraud or with a reckless disregard for the truth and in doing so made material misrepresentations or omissions of material fact in the Lyondell Documents, as applicable; provided, however, that for this purpose Lyondell's applicable share of Defense Costs shall in no event exceed those Defense Costs that Lyondell would have incurred in the absence of ARCO's undertaking to pay Defense Costs as provided in this Section 12; and provided, further, that this Section 12 shall be of no force and effect in the event ARCO owns less than 20 percent of the issued and outstanding Lyondell Common Stock immediately preceding registration pursuant to Section 3 hereof. 13. Miscellaneous. (a) Injunctions. Irreparable damage would occur in the event that any of the provisions of this Agreement was not performed in accordance with its specific terms or was otherwise breached. Therefore, the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof in any court having jurisdiction, such remedy being in addition to any other remedy to which they may be entitled at law or in equity. (b) Severability. If any term or provision of this Agreement is held by a court of competent jurisdiction to be invalid, void, or unenforceable, the parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term or provision; provided, however, that if such effort is not successful, this Agreement shall be deemed to be void and of no further force or effect. (c) Further Assurances. Subject to the specific terms of this Agreement, each of the parties hereto shall make, execute, acknowledge and deliver such other instruments and documents, and take all such other actions, as may be reasonably required in order to effectuate the purposes of this Agreement and to consummate the transactions contemplated hereby. (d) Waivers, Etc. No failure or delay on the part of either party hereto in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, 12 preclude any other or further exercise thereof or the exercise of any other right or power. No modification or waiver of any provision of this Agreement nor consent to any departure therefrom shall in any event be effective unless the same shall be in writing, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. (e) Entire Agreement and Amendment. This Agreement contains the entire understanding of the parties with respect to the subject matter hereof. The section headings contained in this Agreement are solely for the purpose of reference, and shall not in any way affect the meaning or interpretation of this Agreement. This Agreement may not be amended either in whole or in part except in writing executed by ARCO and Lyondell which refers to this Agreement; any such amendment shall bind transferees pursuant to Section 11 and Designated Defendants pursuant to Section 12. (f) Counterparts. For the convenience of the parties, this Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original but all of which together shall be one and the same instrument.

(i) Assignment. Except as provided herein, the parties may not assign their rights under this Agreement. Lyondell may not delegate its obligations under this Agreement. (j) No Third Party Beneficiaries. The parties hereto agree that (i) no other person other than a transferee pursuant to Section 11 or the Designated Defendants pursuant to Section 12 shall have any 13 rights or remedies under or by reason of this Agreement, whether as a third party beneficiary or otherwise, and (ii) the parties hereto shall retain full rights and power to amend or modify this Agreement pursuant to an agreement entered into by the parties in writing, except that no such amendment or modification shall act to impair the rights of a transferee then existing pursuant to Section 11 without the consent in writing of such transferee. (k) Termination. ARCO and Lyondell hereby agree that, if the Notes offering is not consummated pursuant to the terms of the Underwriting Agreement, this Agreement shall terminate immediately. (l) Underwriting Agreement. In connection with the Underwriting Agreement, ARCO and Lyondell hereby agree as follows: (i) All references in the Underwriting Agreement to statements or omissions made in reliance upon or in conformity with information furnished in writing to ARCO by Lyondell either directly or through an "Underwriter" (which term is defined, for purposes of this paragraph (l), as in the Underwriting Agreement), shall be deemed to refer only to the information in the "ARCO Registration Statement" or "ARCO Prospectus" (which terms are defined, for purposes of this paragraph (l), as in the Underwriting Agreement) included under the heading designated "LYONDELL PETROCHEMICAL COMPANY" (excluding the first paragraph thereof); and (ii) All references in the Underwriting Agreement to statements or omissions made in reliance upon or in conformity with information furnished in writing to Lyondell by ARCO either directly or through an Underwriter, shall be deemed to refer only to the information in the "Lyondell Registration Statement" or "Lyondell Prospectus" (which terms are defined, for purposes of this paragraph (l), as in the Underwriting Agreement) included under the heading designated "RELATIONSHIP WITH ARCO--General" and "--Registration Rights Agreement with ARCO."
