     WHEREAS, Executive Jet Management (“EJM”) manages and maintains the Aircraft for the benefit of the Lyondell, including providing a fully qualified flight crew to operate the Aircraft; and

     WHEREAS, Lyondell desires to periodically lease said Aircraft with flight crew to Employee and Employee desires to periodically lease said Aircraft and flight crew from Lyondell on a time sharing basis pursuant to Section 91.501(c)(1) of the Federal Aviation Regulations (“FARs”).

     NOW THEREFORE, Lyondell and Employee declaring their intention to enter into and be bound by this Agreement, and for the good and valuable consideration set forth below, hereby covenant and agree as follows:

1. Subject to the terms and conditions of this Agreement, Lyondell agrees to periodically lease the Aircraft to Employee for Employee’s personal travel pursuant to the provisions of FAR Section 91.501(c)(1) and to provide a fully qualified flight crew for all operations of the Aircraft, all on an as available, as needed, non-continuous, non-exclusive basis commencing on the first date set forth hereinabove and continuing unless and until terminated. Either party may terminate this Agreement by giving thirty (30) days written notice to the other party. This Agreement will terminate if Employee’s employment with or services as an employee of Lyondell terminates.

2. Employee shall pay Lyondell for each flight conducted under this Agreement the lesser of: a. the product of the number of estimated incremental flight hours for the flight as provided by EJM on the applicable flight passenger manifest, multiplied by the per-hour variable costs for the Aircraft as determined by Lyondell, plus incremental expenses such as travel expenses of the crew and in-flight food and beverages; or, b. the actual expenses of each specific flight, as authorized by FAR Section 91.501(d), including the actual expense of any “deadhead” flights made for Employee, as authorized by FAR Section 91.501(d). The expenses authorized by FAR Section 91.501(d) include:

i.	fuel, oil, lubricants, and other additives;
ii.	travel expenses of the crew, including food, lodging and ground transportation;

iii. hangar and tie down costs away from the aircraft’s base of operation;

iv. insurance obtained for the specific flight;

v. landing fees, airport taxes and similar assessments; vi. customs, foreign permit, and similar fees directly related to the flight;

vii. in-flight food and beverages;

viii. passenger ground transportation;

ix. flight planning and weather contract services; and x. an additional charge equal to 100% of the expenses listed in subparagraph (i) above.

3. Lyondell will pay all expenses related to the operation of the Aircraft when incurred, and will provide an invoice to and xxxx Employee for the amount determined in accordance with paragraph 2 hereof within sixty (60) days of any flight or flights for the account of Employee. Employee shall pay Lyondell said amount within thirty (30) days of receipt of the invoice.

4. Employee shall include with each payment any federal transportation excise tax due with respect to such payment, and Lyondell shall be responsible for collecting, reporting and remitting such tax to the U.S. Internal Revenue Service.

5. Employee acknowledges that during the term of this Agreement the Aircraft will be subject to use by Lyondell, including the leasing, if any, thereof to other of Lyondell’s employees under time sharing arrangements with terms similar to this Agreement. If Employee and another such person lease the Aircraft for the same flight segment, the charges for that segment shall be allocated between or among them on a pro-rata basis and the total charge for the flight shall not exceed the payment described under paragraph 2 hereof.

6. To the extent the amount paid by Employee under paragraph 2 hereof for a flight is less than the amount of income required to be imputed for such flight under the provisions of the Internal Revenue Code of 1986 (and as thereafter amended) applicable to personal use of corporate aircraft, the Employee will be imputed income for said difference.

7. Employee will provide Lyondell with requests for flight time and proposed flight schedules as far in advance of any given flight as possible. Requests for flight time and proposed flight schedules shall be made in compliance with Lyondell's scheduling procedures. In addition to proposed schedules and flight times, Employee shall provide at least the following information for each proposed flight at some time prior to scheduled departure as required by Lyondell or Lyondell's flight crew:

a.	proposed departure point;
b.	destination;
x.	xxxx and time of flight;
d.	the number and name(s) of all anticipated passengers;
e.	the nature and extent of unusual luggage and/or cargo to be carried, if any;
f.	the date and time of a return flight, if any; and
g.	any other information concerning the proposed flight that may be pertinent or

8. Lyondell shall pay all expenses related to the leasing of the Aircraft from CFS and the operation of the Aircraft and shall engage, pay for and provide to Employee a qualified flight crew for each flight undertaken under this Agreement through EJM.

9. Lyondell shall be responsible for contracting for maintenance, preventive maintenance and required or otherwise necessary inspections on the Aircraft, and shall take such requirements into account in scheduling the Aircraft. No period of maintenance, preventive maintenance or inspection shall be delayed or postponed for the purpose of scheduling the Aircraft, unless said maintenance or inspection can be safely conducted at a later time in compliance with all applicable laws and regulations, with EJM’s established policies for such managed aircraft and within the sound discretion of the pilot in command. The pilot in command shall have final and complete authority to cancel any flight for any reason or condition which in the pilot’s judgment would compromise the safety of the flight.

10. In accordance with applicable FARs, the flight crew will exercise all of its duties and responsibilities in regard to the safety of each flight conducted hereunder. Employee specifically agrees that the pilot in command, in the pilot’s sole discretion, may terminate any flight, refuse to commence any flight, or take other action which in the considered judgment of the pilot in command is necessitated by considerations of safety. The parties agree that Lyondell shall not be liable for delay or failure to furnish the Aircraft and/or a crew member pursuant to this Agreement when such failure is caused by government regulation or authority, mechanical difficulty, war, civil commotion, strikes or labor disputes, weather conditions, or acts of God.

11.      Lyondell and Employee agree with respect to the following indemnification provisions: a. Lyondell hereby indemnifies Employee and agrees to hold harmless Employee

from and against any liabilities, obligations, losses (excluding loss of anticipated profits), damages, claims, actions, suits, costs, expenses and disbursements (“Losses”) imposed on, incurred by or asserted against Employee arising out of or resulting from the lease, maintenance, repair, possession, use, operation, condition, or other disposition or application of the Aircraft. Lyondell’s obligation to indemnify Employee under this paragraph 11 shall not, however, extend to any Loss (i) resulting from the willful misconduct or gross negligence of Employee, (ii) to the extent such Loss is a direct result of any failure of Employee to comply with any covenants required to be performed or observed by Employee under this Agreement, or (iii) to the extent such Loss is a direct result of any breach by Employee of any of Employee’s warranties or representations contained in this Agreement. b. Employee hereby indemnifies Lyondell and agrees to hold harmless Lyondell from and against any Losses imposed on, incurred by or asserted against Lyondell (i) arising out of or resulting from the willful misconduct or gross negligence of Employee, (ii) to the extent such Loss is a direct result of any failure of Employee to comply with any covenants required to be performed or observed by Employee, or (iii) to the extent such Loss is a direct result of any breach by Employee of any of Employee’s warranties or representations contained in this Agreement. c. Lyondell and Employee agree that in the event either party shall be liable to the other for any reason under this Agreement, that under no circumstances shall the damaged party be entitled to any special or consequential damages, including but not limited to damages for lost profits.

12. The risk of loss during the period when any Aircraft is operated on behalf of Employee under this Agreement shall remain with Lyondell, and Lyondell will retain all rights and benefits with respect to the proceeds payable under policies of hull insurance maintained by Lyondell that

may be payable as a result of any incident or occurrence while an Aircraft is being operated on behalf of Employee under this Agreement. Employee shall be named as an additional insured on liability insurance policies maintained by Lyondell on the Aircraft with respect to flights conducted pursuant to this Agreement. The liability insurance policies on which Employee is named an additional insured shall provide that as to Employee coverage shall not be invalidated or adversely affected by any action or inaction, omission or misrepresentation by Lyondell or any other person (other than Employee). Any hull insurance policies maintained by Lyondell on any Aircraft used by Employee under this Agreement shall include a waiver of any rights of subrogation of the insurers against Employee. Lyondell will provide such additional insurance coverage as Employee shall request or require, provided, however, that the cost of such additional insurance shall be borne by Employee as set forth in paragraph 2 hereof.

13.      Employee warrants that for all use of the Aircraft pursuant to this Agreement: a. Employee will use the Aircraft for and on account of Employee’s own personal

business or pleasure only, and will not use the Aircraft for the purposes of providing transportation for passengers or cargo in air commerce for compensation or hire; b. Employee shall refrain from incurring any mechanics or other lien in connection with inspection, preventative maintenance, maintenance or storage of the Aircraft, whether permissible or impermissible under this Agreement, and Employee shall not attempt to convey, mortgage, assign, lease or any way alienate the Aircraft or create any kind of lien or security interest involving the Aircraft or do anything or take any action that might mature into such a lien; and c. During the term of this Agreement, Employee will abide by and conform (and will cause any passengers in Employee’s party to abide by and conform) to all such laws, governmental and airport orders, rules and regulations, and directives of the pilot in charge as shall from time to time be in effect relating in any way to the operation and use of the Aircraft.

14. For purposes of this Agreement, the permanent base of operations of the Aircraft shall be Xxxxxxx X. Hobby Airport, Houston, Texas.
