(iii) IPO Incentive Share Awards. In the event the Company or any parent of the Company is successful in completing an initial public offering of its common stock (the “IPO,” and to the extent the IPO relates to the common stock of the Company’s parent, Executive will, at the Company’s request, enter in an amendment of this Agreement to reflect the appropriate entity as the “Company”)

13

10. Section 409A Compliance. To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A of the Internal Revenue Code of 1986, as amended, and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the date hereof (“409A Guidance”). Notwithstanding any provision of the Agreement to the contrary, (i) if, at the time of the Executive’s termination of employment with the Company, the Executive is a “specified employee” as defined in 409A Guidance and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under 409A Guidance, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided to the Executive) until the date that is six months following the Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A) and (ii) if any other payments of money or other benefits due to the Executive hereunder could cause the application of an accelerated or additional tax under Section 409A, the Company may (a) adopt such amendments to the Agreement, including amendments with retroactive effect, that the Company determines necessary or appropriate to preserve the intended tax treatment of the benefits provided by the Agreement and/or (b) take such other actions as the Company determines necessary or appropriate to comply with the requirements of 409A Guidance. The Company shall consult with the Executive in good faith regarding the implementation of this Section 10; provided that none of the Company, any of its affiliates, or any of its employees or representatives shall have any liability to the Executive with respect thereto.

11. Remedies. It is specifically understood and agreed that any breach of the provisions of Section 8 or Section 9 of this Agreement is likely to result in irreparable injury to the Company and that the remedy at law alone will be an inadequate remedy for such breach, and that in addition to any other remedy it may have, the Company shall be entitled to enforce the specific performance of this Agreement by the Executive and to obtain both temporary and permanent injunctive relief without bond and without liability should such relief be denied, modified or violated. Neither the right to obtain such relief nor the obtaining of such relief shall be exclusive or preclude the Company from any other remedy.

12. Severability.

14. Arbitration of Disputes. (a) Any dispute, controversy, or claim (collectively, any “Dispute”) arising between the Company and the Executive relating to or arising from this Agreement other than the Company’s right to seek injunctive relief for breach of Section 8 or Section 9 of this Agreement, shall be submitted to and settled by binding arbitration in the Las Vegas, Nevada office of the American Arbitration Association (“AAA”) conducted pursuant to the rules then in effect of the AAA governing employment disputes, before three (3) neutral arbitrators licensed to practice law for at least ten years and familiar with employment law disputes (or at any other place or under any other form of arbitration mutually acceptable to the parties so involved). Any award rendered in any Dispute shall be final and conclusive upon the parties to the arbitration, and the judgment thereon may be entered in the highest court of the forum (state or federal) having jurisdiction over the issues addressed in the arbitration. The administration fees and expenses of the arbitration shall be borne equally by the parties to the arbitration, provided that each party shall pay for and bear the cost of its/his/her own experts, evidence and attorney’s fees. In the discretion of the arbitrators, any award may include the cost of a party’s counsel and/or its share of the expense of arbitration, if the arbitrators expressly determine that an award of such costs is appropriate to the party whose position prevails in such arbitration. To submit a

15

matter to arbitration, the party seeking redress (“Claimant”) shall notify in writing the party against whom such redress is sought (“Respondent”), describe the nature of such claim, the provision of this Agreement that has been violated by the Respondent and the material facts surrounding such claim. At any arbitration hearing, each of the parties shall have the right to make both written and oral presentations to the arbitrators. Within thirty (30) days of the conclusion of such arbitration hearing, the arbitrators shall render a single written decision. The decision of the arbitrators shall be binding upon the Claimant and Respondent, and after the completion of such arbitration, the Claimant and Respondent may only institute litigation regarding the Dispute for the sole purpose of enforcing the determination of the arbitration hearing. By agreeing to arbitration under this Section 14, the Company and the Executive understand that they are each waiving any right to a trial by jury and each party makes that waiver knowingly and voluntarily with full consideration of the ramifications of such waiver.

Schedule 1

Target Bonus

		Percentage that Actual EBITDA for a fiscal year represents of Budgeted EBITDA for such fiscal year
		80%			100%			110%
Percentage of Base Salary payable as Target Bonus		0	%		80	%		120	%

The Target Bonus payable to the Executive hereunder for each fiscal year is to be interpolated for Actual EBITDA between 80% and 100% or between 100% and 110% of Budgeted EBITDA.

For example, if Actual EBITDA represents 85% of Budgeted EBITDA, a Target Bonus of 20% of the Executive’s Base Salary would be payable, calculated as follows:

(1) The increase of Actual EBITDA over the 80% of Budgeted EBITDA benchmark, which in this case equals 5%, is divided by the difference between (a) 100% and (b) 80% (the two applicable Budgeted EBITDA benchmarks), yielding 25%;

(2) This amount (25%) is then multiplied by the difference between (x) 80% (the Target Bonus at 100% of Budgeted EBITDA) and (y) 0% (the Target Bonus at 80% of Budgeted EBITDA), which equals 20% of the Executive’s Base Salary as the Target Bonus.

On the other hand, if Actual EBITDA represents 105% of Budgeted EBITDA, then a Target Bonus of 100% of the Executive’s Base Salary would be payable, calculated as follows:

(1) The increase of Actual EBITDA over the 100% of Budgeted EBITDA benchmark, which in this case equals 5%, is divided by the difference between (a) 110% and (b) 100% (the two applicable Budgeted EBITDA benchmarks), yielding 50%;

(2) This amount (50%) is then multiplied by the difference between (x) 120% (the Target Bonus at 110% of Budgeted EBITDA) and (y) 80% (the Target Bonus at 100% of Budgeted EBITDA), which equals 20% of the Executive’s Base Salary as the Target Bonus payable for the increase of 5% over the 100% Budgeted EBITDA Benchmark;

(3) This amount (20% of Base Salary) is then added to the 80% of Base Salary that was earned when Actual EBITDA met the 100% of Budgeted EBITDA Benchmark, which equals an aggregate total of 100% of the Executive’s Base Salary as the Target Bonus.
