EXHIBIT 1.1 DEALER-MANAGER AGREEMENT July 1, 1998 PaineWebber Incorporated 1285 Avenue of the Americas New York, New York 10019 Ladies and Gentlemen: This agreement (the "Agreement") will confirm the understanding between Pennzoil Company, a Delaware corporation, and its subsidiaries (collectively, the "Company") and PaineWebber Incorporated ("PaineWebber") pursuant to which the Company has retained PaineWebber to act as its exclusive dealer manager, on the terms and subject to the conditions set forth herein, in connection with the proposed offer by the Company to acquire, a portion of the Company's 4 3/4% Exchangeable Senior Debentures due 2003 and 6 1/2% Exchangeable Senior Debentures due 2003 (together being the "Securities") and the issuance by the Company of newly issued 4.95% Exchangeable Senior Debentures due 2008 and 4.90% Exchangeable Senior Debentures due 2008 (the "New Debentures"), with principal amounts to be determined as set forth in the Prospectus referred to below. The New Debentures will be two series of the Company's debt securities and will be issued under the Indenture dated as of December 15, 1992 and the Third Supplemental Indenture and Fourth Supplemental Indenture thereto (the "Supplemental Indentures"), both between the Company and Chase Bank of Texas, N.A (formerly known as Texas Commerce Bank, N.A.) (the "Trustee"). The transactions, which are intended to result in the partial acquisition of the Securities by or on behalf of the Company as proposed to be accomplished through an exchange of Securities by the Company, are referred to herein as the "Exchange Offers." The making of the Exchange Offers, the exchange of Securities pursuant thereto, and all related incidental acts and transactions are hereinafter referred to collectively as the "Exchange Offers Transactions." The following sets forth the agreement between the Company and PaineWebber: Section 1. Appointment as Dealer Manager. The Company hereby appoints PaineWebber on an exclusive basis to act as financial advisor with respect to the Exchange Offers Transactions and as sole dealer manager for the Exchange Offers, and hereby authorizes PaineWebber to act as such in connection therewith. PaineWebber agrees to perform those services as dealer manager with respect to the Exchange Offers as are customarily performed by PaineWebber in connection with tender offers of a like nature, including (but not limited to) providing certain advice to the Company regarding the terms and timing of the Exchange Offers and using its best efforts to solicit tenders of Securities pursuant to the Exchange Offers and in communicating with other brokers, dealers, commercial banks and trust companies (collectively, "Dealers"). In soliciting or obtaining tenders, (i) PaineWebber, as dealer manager, shall act as an independent contractor with duties solely to the Company and shall not be deemed to be acting as the agent of the Company other than pursuant to this Agreement or as the agent of any Dealer, (ii) the Company will not pay any person any commission or other remuneration, directly or indirectly, for the solicitation of the Exchange Offers (other than PaineWebber) and (iii) no Dealer shall be deemed to be acting as the agent of PaineWebber; provided, however, that the Company hereby authorizes PaineWebber, and/or one or more registered brokers or dealers chosen by PaineWebber, to act as the Company's agent in making the Exchange Offers to residents of any jurisdiction in which such agent designation may be necessary to comply with applicable law. Nothing in this Agreement shall constitute PaineWebber as a partner or joint venturer with the Company or any of its subsidiaries. It is understood that PaineWebber is being engaged hereunder solely to provide the services described above on behalf of the Company, and that PaineWebber is not acting as an agent or fiduciary of, and shall have no duties or liability to, the equity holders of the Company or any other third party in connection with its engagement hereunder, all of which are hereby expressly waived. On the basis of the representations and warranties and agreements of the Company contained herein and subject to and in accordance with the terms and conditions hereof and of the Exchange Offers, PaineWebber agrees to act in such capacity. Section 2. Exchange Offer Materials. Prior to the commencement of the Exchange Offers, the Company agrees to furnish PaineWebber, at the Company's expense, with as many copies as PaineWebber may reasonably request of (i) each of the documents that is filed with the Securities and Exchange Commission (the "Commission"), including each registration statement, preliminary and final prospectus filed with the Commission (such final prospectus included in such registration statement as amended at the time it becomes effective is herein called the "Prospectus," except that, if the prospectus first filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission shall differ from the Prospectus, the term "Prospectus" shall also include the prospectus first filed pursuant to Rule 424(b)), in connection with the Exchange Offers, (ii) each offering circular, sales memorandum, term sheet, proposed agreement, invitation to negotiate, private placement memorandum, solicitation statement, disclosure document, or other explanatory statement, or other report, filing, document, release or communication mailed, delivered, published, or filed by or on behalf of the Company in connection with the Exchange Offers, (iii) each document required to be filed with the Commission pursuant to the provisions of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), pertaining to the Company during the term of this Agreement and (iv) each appendix, attachment, modification, amendment or supplement to any of the foregoing and all related documents, including but not limited to each related letter of transmittal (each of (i), (ii), (iii) and (iv), an "Exchange Offer Document" and, collectively, the "Exchange Offer Documents"). At the commencement of the Exchange Offers, the Company shall cause timely to be delivered to each registered holder of any Securities legally or contractually entitled thereto, each Exchange Offer Document and any other offering materials prepared expressly for use by holders of Securities tendering, voting, or otherwise participating in the Exchange Offers, together with a return envelope. Thereafter, to the extent practicable, until the expiration of the Exchange Offers, the Company shall use its best efforts to cause copies of such materials and a return envelope to be mailed to each person who becomes a holder of any Securities. The Company agrees that, at a reasonable time prior to using any material in connection with the Exchange Offers or filing any such material with the Commission or any other federal or state agency, commission or instrumentality, the Company will submit copies of such material to PaineWebber and will consult with PaineWebber and give reasonable consideration to its comments, if any, with respect thereto. In connection with the Exchange Offers, if the Company (a) uses or permits the use of, or files with the Commission or any other governmental or regulatory agency, authority or instrumentality, any Exchange Offer Document that (i) has not been submitted to PaineWebber on a timely basis for PaineWebber's comments or (ii) has been so submitted and with respect to which PaineWebber reasonably objects or (b) shall have breached any of its representations, warranties, agreements, or covenants herein, then PaineWebber shall be entitled to withdraw as a dealer manager in connection with the Exchange Offers, without any liability or penalty to PaineWebber or any other Indemnified Person (as defined in paragraph 6 hereof) for such withdrawal and without loss of any right to indemnification or contribution provided in this Agreement or to the payment of all fees and expenses payable hereunder that have accrued to the date of such withdrawal. In the event of any such withdrawal, for the purpose of determining the fees payable to PaineWebber pursuant to this Agreement, PaineWebber shall remain entitled to receive the payment of all fees and expenses payable under this Agreement that have accrued to the date of any such withdrawal. The Company recognizes and confirms that, in connection with the Exchange Offers, PaineWebber will be using and relying upon (i) information (both written and oral), documents (including the Exchange Offer Documents) and data furnished by the Company to PaineWebber, and (ii) information available from filings made by the Company pursuant to the Exchange Act which have been approved for such use by the Company (collectively the "Information"). The Company further recognizes that PaineWebber does not assume responsibility for the accuracy or completeness of the Information and will not undertake to independently verify its accuracy or completeness. The Company agrees that any reference to PaineWebber or any affiliate of PaineWebber in any Exchange Offer Document, or any release or written communication, is subject to PaineWebber's prior approval. If PaineWebber resigns prior to the dissemination of any Exchange Offer Document or any release or communication, no reference shall be made therein to PaineWebber. 2 Section 3. Compensation. The Company will pay PaineWebber for services to be rendered by PaineWebber hereunder as set forth in the compensation provisions of the agreement dated August 1, 1997, between Pennzoil Company and PaineWebber (the "Prior Agreement"), the first amendment thereto dated December 19, 1997 (the "First Amendment") and the second amendment thereto dated June 24, 1998 (the "Second Amendment"), which compensation provisions are incorporated as if restated herein in full and shall remain as a part of this Agreement notwithstanding any termination, amendment or purported invalidity of the Prior Agreement, First Amendment or Second Amendment. Section 4. Expenses; Reimbursement Thereof. The Company will pay or cause to be paid (i) all fees and expenses relating to the preparation, printing, filing, mailing and publishing of all documents pertaining to the Exchange Offers; (ii) all fees and expenses of any depositary, information agent or other agents, attorneys and other persons retained by the Company in connection with the Exchange Offers; (iii) all fees, if any, payable to Dealers (including PaineWebber) as reimbursement for their customary mailing and handling expenses in forwarding materials related to the Exchange Offers to their customers; (iv) all advertising charges; and (v) all other fees and expenses incurred in connection with or relating to the Exchange Offers. In addition, the Company agrees to reimburse PaineWebber and its affiliates, promptly upon request, for all out-of-pocket expenses, including (without limiting the foregoing) the fees, costs and expenses of PaineWebber's legal counsel, incurred in connection with the Exchange Offers Transactions. Section 5. Limitation on Liability. Neither PaineWebber nor any affiliate thereof shall have any liability to the Company or any affiliate thereof for any losses, claims, damages, liabilities or expenses ("Liabilities") arising from any act or omission on the part of any Dealer, or from PaineWebber's acts or omissions in performing its obligations hereunder or otherwise in connection with the Exchange Offers Transactions, except to the extent that such Liabilities are finally and judicially determined by a court of competent jurisdiction to have resulted primarily from PaineWebber's willful misconduct or gross negligence. Section 6. Indemnification and Contribution. The Company hereby agrees (i) to indemnify and hold harmless PaineWebber, its affiliated companies, and each of PaineWebber's and such affiliated companies' respective officers, directors, agents, employees and controlling persons (within the meaning of Section 20 of the Exchange Act and Section 15 of the Securities Act of 1933, as amended (the "Securities Act")) (each of the foregoing, including PaineWebber, being hereafter sometimes called an "Indemnified Person"), to the fullest extent permitted by law from and against any and all Liabilities, actions (including shareholder derivative actions), proceedings, investigations (whether formal or informal) or inquiries, or threats thereof, based on or arising out of (1) any untrue statement or alleged untrue statement of any material fact in any Exchange Offer Document, (2) any omission or alleged omission of any material fact required to be stated in any Exchange Offer Document or necessary to make the statement made in any Exchange Offer Document, in light of the circumstances under which it was made, not misleading, (3) any withdrawal, termination or cancellation of any one or more of the Exchange Offers Transactions for any reason whatsoever, (4) any tender, purchase, exchange or other acquisition by the Company or any affiliate thereof of Securities (including, without limiting the foregoing, any purchase prior to the date hereof as to which PaineWebber acted as broker or dealer), (5) any violation by or conflict of the Exchange Offers or any of the Exchange Offers Transactions of or with any law, rule, regulation, order, award, judgment, determination, writ, injunction or decree of any United States federal, state, local or foreign court or governmental authority, (6) any breach by the Company of any representation or warranty or any failure to comply with any of the agreements contained herein or any agreement relating to the Exchange Offers or the Exchange Offers Transactions, or (7) the Exchange Offers, the Exchange Offers Transactions or PaineWebber's engagement hereunder, and (ii) in connection with the foregoing obligations, to reimburse each Indemnified Person for all expenses (including fees, disbursements and other charges of counsel) as they are incurred by such Indemnified Person in connection with investigating, preparing to defend or defending any such action (including actions brought by the Company or 3 the Company's equity holders or derivative actions brought by any person claiming through the Company or in the Company's name), proceeding, investigation or inquiry, or threat thereof, whether or not any such action, proceeding, investigation or inquiry is actually or formally commenced or any such Indemnified Person is a party thereto or subject thereof. Notwithstanding the foregoing, the Company shall not be obligated to indemnify any such Indemnified Person under this Section 6 with respect to any Liability, and amounts paid in reimbursement of expenses under this Section 6 shall be refunded, to the extent, but only to the extent, that is finally and judicially determined (i) that such Liability resulted primarily from an untrue statement of any material fact in any Exchange Offer Document or any omission to state any material fact required to be stated in any Exchange Offer Documents, or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading, if, in any such case, such statement or omission was made in such Exchange Offer Documents in reliance upon and in conformity with written information prepared by and relating to PaineWebber and furnished to the Company in writing by PaineWebber or (ii) in the case of Liabilities against which Indemnified Persons are indemnified solely under clause (i)(7) of the preceding sentence, that such Liability resulted primarily from the willful misconduct or gross negligence of such Indemnified Person. If multiple claims are brought against any Indemnified Person in an arbitration or other proceeding and at least one such claim is based upon, relates to or arises out of PaineWebber's services hereunder or any Indemnified Person's role thereunder, the Company agrees that any award, judgment and other liabilities resulting therefrom shall be deemed conclusively to be based on, relate to or arise out of PaineWebber's services hereunder or any Indemnified Person's role thereunder, except to the extent that such award or judgment expressly states that the award or judgment, or any portion thereof, is based solely upon, relates to or arises out of other matters for which indemnification is not available hereunder. PaineWebber agrees to indemnify and hold harmless the Company, its director, trustees and officers who sign the Registration Statement (as defined in Section 7(v) below), and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity from the Company to PaineWebber contained herein, but only with reference to information relating to PaineWebber furnished to the Company in writing by PaineWebber expressly for use in the Registration Statement, any preliminary prospectus, the Prospectus, any other Exchange Offer Document or any amendment or supplement thereto. The Company acknowledges that the only information relating to PaineWebber furnished to the Company in writing by PaineWebber expressly for use in the Registration Statement, any preliminary prospectus, the Prospectus, any other Exchange Offers Documents or any amendment or supplement thereto is PaineWebber's name and information provided under the caption "Dealer Manager". If any litigation, proceeding or investigation is instituted or threatened against any Indemnified Person in respect of which indemnity may be sought against the Company pursuant to this Section 6, such indemnified person shall promptly notify the Company thereof, in writing, but the omission to so notify the Company shall not relieve the Company from any obligation or liability under this Section 6, unless, and only to the extent that, such omission to so notify results in the loss of substantive rights or defenses. If any such litigation or proceeding shall be brought against any Indemnified Person, the Company shall be entitled to participate in such litigation or proceeding, and, after written notice from the Company to such Indemnified Person, to assume the defense of such litigation or proceeding with counsel of the Company's choice at its expense; provided, however, that such counsel shall be satisfactory to the Indemnified Person. Notwithstanding the election of the Company to assume the defense of such litigation or proceeding, such Indemnified Person shall have the right to employ separate counsel at the expense of such Indemnified Person and to control its own defense of such litigation or proceeding. The Company shall bear the fees and disbursements of separate counsel only if (i) the Company and such Indemnified Person shall have mutually agreed to the retention of such counsel, (ii) there may be legal defenses available to such Indemnified Person or to other Indemnified Persons that are different from or additional to those available to the Company or (iii) a conflict or potential conflict otherwise exists between such Indemnified Person and the Company that would make such separate representation advisable; provided, however, that the Company shall not under any circumstances be liable hereunder for the expenses of more than one firm of attorneys in any jurisdiction in any one legal action or group of related legal actions. In the case of any such separate firm for PaineWebber and such partners, directors, officers and control persons of PaineWebber or its affiliates, such firm 4 shall be designated in writing by PaineWebber. In the case of any such separate firm for the Company, and such directors, officers, trustees and control persons of the Company, such firm shall be designated in writing by the Company. The Company agrees that it will not, without the prior written consent of PaineWebber, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the Exchange Offers Transactions or PaineWebber's engagement hereunder (whether or not any Indemnified Person is a party thereto) unless such settlement, compromise or consent includes an unconditional release of PaineWebber and each other Indemnified Person from all liability arising or that may arise out of such claim, action or proceeding. The Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Company agrees to indemnify the Indemnified Person from and against any Liabilities by reason of such settlement or judgment. If the indemnification provided for in this Section 6 is held by a court of competent jurisdiction to be unavailable to any Indemnified Person in respect of any Liabilities referred to herein (other than as a consequence of a final judicial determination as set forth in the second sentence of the first paragraph of this Section 6), then the Company in lieu of indemnifying such Indemnified Person, shall contribute to the amount paid or payable by such Indemnified Person as a result of such Liabilities in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by such Indemnified Person on the other from the Exchange Offers Transactions. If the allocation provided in the preceding sentence is not permitted by applicable law, or as a consequence of a final judicial determination as set forth in the second sentence of the first paragraph of this Section 6, then the Company agrees to contribute to the amount paid or payable by such Indemnified Person as a result of such Liabilities in such proportion as is appropriate to reflect not only the relative benefits referred to in the preceding sentence, but also the relative fault of the Company on the one hand and of such Indemnified Person on the other in connection with the statements or omissions or other actions relating to or in connection with the Exchange Offers Transactions or PaineWebber's engagement hereunder that resulted in such Liabilities. Notwithstanding the foregoing, in no event shall the aggregate amount contributed by the Indemnified Persons taking into account the contribution of Company as described above exceed the amount of fees actually paid to PaineWebber by Company pursuant to this Agreement in connection with the Exchange Offers Transactions. The relative benefits received by the Company on the one hand and PaineWebber on the other shall be deemed to be in the same proportion as (i) the aggregate value of the maximum number of Securities offered to be exchanged pursuant to the Exchange Offers bears to (ii) the fees paid to PaineWebber pursuant to this Agreement. The relative fault of the Company on the one hand and of PaineWebber on the other shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of, or any omission or alleged omission to state, a material fact relates to information supplied by the Company or by PaineWebber and by reference to the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The foregoing indemnification and contribution agreement shall be in addition to any rights that any Indemnified Person may have at common law, by separate agreement or otherwise. Section 7.
