WHEREAS, the Company owns and has the exclusive right to possess, use and operate the Raytheon Hawker 4000 aircraft bearing manufacturer serial number RC-54 and United States FAA Registration No. N837RE (the “Aircraft”); and

WHEREAS, the Company has entered into an Aircraft Management Agreement, dated as of September 20, 2011 between the Company and Executive Jet Management, Inc. (the “Aircraft Management Agreement”), for Executive Jet Management, Inc. to provide a fully qualified flight crew acceptable to and approved by the Company to operate the Aircraft; and

WHEREAS, the Executive is the Chief Executive Officer and President of the Company; and

WHEREAS, the Company and the Executive desire to lease the Aircraft and the flight crew from time to time on a time sharing basis, as defined in Section 91.501(c) (1) of the Federal Aviation Regulations (“FAR”).

NOW, THEREFORE, in consideration of the foregoing, and based on the mutual covenants and conditions set forth herein, the Parties agree as follows:

1. Lease of Aircraft. Pursuant to and in accordance with the provisions of FAR 91.501(c)(1), the Company hereby agrees to lease the Aircraft from time to time to the Executive on a time sharing, non-continuous and non-exclusive basis and the Executive hereby agrees to lease the Aircraft from time to time from the Company on a time sharing, non-continuous and non-exclusive basis, during the Term (as defined in Section 8) and subject to the terms and conditions herein contained.

2. Delivery and Redelivery of Aircraft. Upon the request of the Executive, subject to the availability of the Aircraft as determined by the Company in accordance with Section 3, the Company shall make the Aircraft available to the Executive at such locations as the Executive may reasonably request. The Executive acknowledges that the Company currently bases the Aircraft at Centennial Airport, (KAPA) Englewood, Colorado (the “Home Base”). The repositioning, ferry or dead head flights of the Aircraft required in connection with the Executive’s flights of the Aircraft under this Agreement, including delivery and/or redelivery of the Aircraft to the Home Base or to such other location as determined by the Company’s specific schedule of the Aircraft usage for its intended business or as the Parties may otherwise agree, shall be deemed to be use of the Aircraft by the Executive and at the Executive’s expense subject to the Rent (as defined in Section 4).

3. Availability, Scheduling and Use of Aircraft Flights. The Executive shall advise the Company of his request for flight time and use of the Aircraft under this Agreement by giving the Company advance notice by telephone and/or facsimile and/or electronic mail as far in advance of any given flight as possible, and in any case, at least two (2) business days in advance of the Executive’s planned departure (unless the Company agrees to a shorter notice in its sole discretion). The Executive’s notice shall provide the customary information required by the Company and its flight crew for each proposed flight, including the following: (i) proposed departure point, (ii) destination, (iii) date and time of flight, (iv) the number and name of the anticipated passengers, (v) the nature and extent of luggage and/or cargo to be carried, (vi) the date and time of return flight, if any, and (vii) any other information concerning the proposed flight that may be pertinent or required by the Company or the Company’s flight crew. The Company, in its sole discretion, shall have final authority over the scheduling of the Aircraft and in the event of a scheduling conflict, the Company’s plans and decisions shall control.

4. Rent. For each flight, including the repositioning, ferry or dead head flights set forth under Section 2 above, conducted under this Agreement, the Executive shall pay to the Company rent (the “Rent”) as may be set by the Company’s Board of Directors from time to time for those flight expenses that may be charged in accordance with FAR § 91.501(d).

5. Rent Limitation. In the unlikely event that the valuation of a flight transporting the Executive and/or his guests on board the Aircraft under this Agreement using the special non-commercial flight valuation rule for a control employee determined under the base aircraft valuation formula (also known as the Standard Industry Fare Level formula or SIFL), in accordance with the applicable provisions of federal income tax regulations § 1.61-21(g) (“Non-Commercial Flight Valuation Taxable Fringe Benefit”), with respect to such flight should exceed the amount of the Rent chargeable for such flight, then such excess difference shall be imputed as taxable compensation to the Executive includable in the Executive’s gross income in accordance with the applicable provisions of the Internal Revenue Code of 1986, as amended, and Treasury Regulations promulgated thereunder and correctly treated and documented for income tax and employment tax and reporting purposes.

6. Federal Excise Tax on Transportation by Air. The Executive agrees and accepts that the Executive shall be responsible for paying to the Company the federal excise tax under Section 4261 of the Internal Revenue Code on the Rent paid to the Company in accordance with Section 4.

7. Method of Payment. The Company will pay all expenses related to the operation of the Aircraft when incurred, and will invoice the Executive for the applicable Rent on the last day of the month in which any flight or flights for the account of the Executive occur.

8. Term and Termination. This Agreement shall be effective on the date set forth above and shall remain in effect until December 15, 2014 or until terminated by either Party upon ten (10) days prior written notice to the other Party (the “Term”); provided however this Agreement shall automatically terminate upon the date that the Executive is no longer employed by the Company.

9. Operational Control and Crew. With respect to each flight undertaken under this Agreement, the Company shall have and retain operational control of the Aircraft as provided in the applicable FAR (as defined in FAR §1.1 “operational control,” with respect to a flight means the exercise of authority over initiating, conducting, or terminating a flight.); and, for federal tax purposes, shall have and retain “possession, command and control” of the Aircraft. The Company shall employ, pay for and provide to the Executive a qualified flight crew for each flight undertaken under this Agreement.

10. Duties and Responsibilities of Crew. In accordance with applicable FAR, the qualified flight crew provided by the Company will exercise all of its duties and responsibilities in regard to the safety of each flight conducted hereunder. The Executive specifically agrees that the flight crew, in its 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 pilot in command shall have final and complete authority to cancel any flight for any reason or condition which in his or her judgment would compromise the safety of the flight. No such action of the pilot in command shall create or support any liability for loss, injury, damage or delay to the Executive or any other person. The Executive acknowledges and agrees that the Company shall not be liable under any circumstances for delay or failure to furnish the Aircraft and crew pursuant to this Agreement, except in the event of willful misconduct by the Company.

11. Maintenance. The Company shall be solely responsible for securing maintenance, preventive maintenance and required or otherwise necessary inspections on the Aircraft, and shall take such requirements into account in scheduling the Aircraft.
