RECITALS

WHEREAS, Company rightfully possesses and operates the aircraft identified in Exhibit A hereto (the "Aircraft") under Part 91 of the Federal Aviation Regulations (“FARs”) incidental to its primary business; and

WHEREAS, Company desires to make the Aircraft available to Lessee, and Lessee desires to utilize the Aircraft, from time to time on a non-exclusive time-sharing basis as authorized under Sections 91.501(b)(6), 91.501(c)(1) and 91.501(d) of the FARs; and

WHEREAS, this Agreement is a time sharing agreement as defined in Section 91.501(c)(1) of the FAR, and use of the Aircraft pursuant to this Agreement will comply with the requirements of FAR 91.501(b)(6), 91.501(c)(1) and 91.501(d).

NOW, THEREFORE, in consideration of the foregoing, and the other agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties, intending to be legally bound hereby, agree as follows:

1. Provision of Aircraft; Term. Company agrees to provide the Aircraft to and operate the Aircraft for Lessee on a non-exclusive basis from time to time as mutually agreed between the parties pursuant to the provisions of FAR 91.501(b)(6), 91.501(c)(1) and 91.501(d), and to provide a fully qualified flight crew for all operations conducted under this Agreement. This Agreement shall be effective on the date set forth above and shall remain in effect until terminated by either party upon ten (10) business days’ prior written notice to the other.

2. Reimbursement of Expenses. Lessee shall pay to Company for each flight conducted under this Agreement a reimbursement not to exceed the sum of the expenses set forth in subparagraphs (a)-(j) below in respect of the specific flight or flights to which such charge applies (including related deadhead flights, if applicable):

(a) Fuel, oil, lubricants, and other additives;

(b) Travel expenses of the crew, including food, lodging, and ground transportation;

(c) Hangar and tie-down costs away from the Aircraft’s base of operation;

(d) Insurance obtained for the specific flight;

(e) Landing fees, airport taxes, and similar assessments;

(f) Customs, foreign permit, and similar fees directly related to the flight;

(g) In-flight food and beverages;

(h) Passenger ground transportation;

(i) Flight planning and weather contract services; and

(j) An additional charge equal to one hundred percent (100%) of the expenses listed in subparagraph (a) above.

Notwithstanding the foregoing, in no event shall reimbursement for the foregoing exceed the actual operating costs of such flight.

For the avoidance of doubt, Lessee shall be responsible to pay over to Company all state and federal taxes and other government fees and charges applicable to each flight conducted under this Agreement; Company, in turn, shall timely remit such taxes, fees and charges to the respective authorities. The parties acknowledge that the federal air transportation excise tax imposed under section 4261 of the Internal Revenue Code of 1986, as amended, may apply to some or all of expense reimbursements provided under this Agreement.

3. Invoicing and Payment. Company will pay all expenses related to the operation of the Aircraft when incurred, and will provide an invoice to Lessee for the reimbursement determined in accordance with paragraph 2 above as promptly as practicable following each flight. Lessee shall pay to Company the reimbursement, together with applicable taxes and other government fees and charges, within thirty (30) days after receipt of the invoice.

4. Flight Information. Lessee will provide Company with requests for flights and proposed flight schedules as far in advance of any given flight as possible, and in any case, at least two (2) business days in advance of Lessee's planned departure (unless Company agrees to a shorter notice in a particular case in its discretion). Requests for flights shall be in a form, whether written or oral, mutually convenient to, and agreed upon by the parties. In addition to the proposed schedules and flight times, Lessee shall provide at least the following information for each proposed flight as far in advance of departure as practicable:

(c) proposed date and time of flight;

(d) the name and relationship to Lessee of all anticipated passengers;

(f) the proposed date and time of return flight, if any; and

(g) any other information concerning the proposed flight that may be pertinent or required by Company or Company’s flight crew.

5. Flight Scheduling. Company shall have final authority over the scheduling of the Aircraft. It is understood that Company shall not be obligated to retain or contract for additional flight crew or maintenance personnel or equipment in order to accommodate Lessee's schedule requests.

6. Operational Control; Maintenance. Company shall be responsible for all aspects of the physical and technical operation of the Aircraft and the safe performance of all flights, and shall retain and exercise exclusive operational control of the Aircraft during all phases of flight, including pre-flight and post-flight duties, and including, without limitation, all flights during which Lessee and/or Lessee’s guests are on-board the Aircraft. Consistent with Company’s operational control responsibilities, Company shall be solely responsible to secure maintenance, preventive maintenance and required or otherwise necessary inspections on the Aircraft, and shall take such requirements into account in scheduling the Aircraft. All costs and expenses related to the maintenance of the Aircraft shall be the responsibility of Company. No period of maintenance, preventative 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, and within the sound discretion of the pilot in command. All flight operations under this Agreement shall be conducted under Part 91 of the FAR.

7. Authority of Pilot in Command and Flight Crew. For each flight conducted under this Agreement, the Aircraft will be operated only by a qualified flight crew.

Lessee specifically agrees that the pilot in command may terminate any flight, refuse to commence any flight, or take other action which in his or her considered judgment is necessitated by considerations of safety or security. No such action of the pilot in command shall create or support any liability for loss, injury, damage or delay to Lessee or any other person. The parties further agree that Company shall not be liable for delay or failure to furnish the Aircraft and crew pursuant to this Agreement for any reason whatsoever.

8. Lessee’s Covenants, Representations and Warranties. Lessee covenants, represents and warrants to Company that during the term of this Agreement:

(a) Lessee shall use the Aircraft for and on account of Lessee’s own business or personal use only, and will not use the Aircraft for the purpose of providing transportation of passengers or cargo for compensation or hire under any circumstances;

(b) Lessee shall refrain from incurring any mechanic’s or other lien relating or attaching to the Aircraft, and shall not attempt to convey, mortgage, assign, lease or in any way alienate the Aircraft or create any kind of lien or security interest involving the Aircraft or take any action that might mature into such a lien; and

(c) Lessee shall, and shall cause any passengers in Lessee’s party to, abide by and conform to all such laws, rules and regulations as may from time to time be in effect relating in any way to the operation or use of the Aircraft under this Agreement.

9. Risk of Loss. As between Lessee and Company, Company assumes and shall bear the entire risk of loss, theft, confiscation, damage to, or destruction of the Aircraft from any cause whatsoever, except to the extent attributable to the gross negligence or willful misconduct of Lessee or Lessee’s guests while aboard on the Aircraft.
