13. Representations, Warranties and Covenants of Optionee.

(a) Optionee acknowledges that neither the Option nor the Option Units covered thereby have been registered under the Securities Act or State Law on the grounds that the issuance of the Option is, and the sale of any Option Units pursuant to the exercise of the Option will be, exempt from registration under one or more provisions of each of such acts. Optionee further understands that in determining the availability and applicability of such exemptions and in executing and delivering this Agreement and issuing and delivering any Option Units upon exercise of the Option, the Company has relied and will rely upon the representations, warranties and covenants made by Optionee herein and in any other documents which he may hereafter deliver to the Company. Accordingly, Optionee represents and warrants to and covenants and agrees with the Company as follows:

(i) Optionee is acquiring and will hold the Option, and will acquire and hold all securities which he acquires upon exercise of the Option, for his own account for investment and not with a view to or in connection with any sale or distribution of all or any part thereof; and

(ii) Optionee will hold all securities acquired by him upon exercise of the Option, as well as any and all other securities issued in respect thereof, subject to all applicable provisions of the Limited Liability Company Agreement, the Securities Act and State Law, and will not at any time make any sale, transfer, pledge or other disposition or encumbrance of any of such securities in violation of the Limited Liability Company Agreement or in the absence of an effective registration statement for such securities under the Securities Act and State Law or an applicable exemption from the registration requirements therefrom.

(b) Optionee agrees (i) that the certificates representing the Option Units or other securities purchased under this Option may bear such legend or legends as the Company deems appropriate in order to assure compliance with applicable securities laws, (ii) that the Company may refuse to register the transfer of the Option Units or other securities purchased under this Option on the transfer records of the Company if such proposed transfer would in the opinion of counsel satisfactory to the Company constitute a violation of any applicable securities laws, (iii) that the Company may give related instructions to its transfer agent, if any, to stop registration of the transfer of the Option Units or other securities purchased under this Option, (iv) that the Option Units or other securities acquired upon exercise of this Option shall be subject, in all respects, to the Limited Liability Company Agreement and (v) Optionee shall become party to the Limited Liability Company Agreement prior to issuance of any certificate representing the Option Units.

(c) Optionee acknowledges that the value of the Option over its life will be speculative and uncertain, that there is no market for the Option or the Option Units or other securities that may be acquired upon exercise of the Option and it is unlikely that any market will develop, and consequently, Optionee may ultimately realize no value from the Option.

14. Optionee’s Employment or Service. Nothing contained in the Plan or in this Agreement shall confer upon Optionee any right with respect to the continuation of his

4

employment by or service with the Company or an Affiliate, or interfere in any way with the right of the Company or an Affiliate, (subject to the terms of any separate agreement to the contrary) at any time to terminate such employment or service or to increase or decrease the compensation of Optionee from the rate in existence at the date of this Agreement.

All notices required or permitted to be given hereunder shall be in writing and shall be deemed to have been given on the earlier of the date of receipt by the party to whom the notice is given or five days after being mailed by certified or registered United States mail, postage prepaid, addressed to the appropriate party (a) if to the Company, at 250 West Main Street, Suite 210, Lexington, Kentucky 40507 and (b) if to Optionee, to Optionee’s address as shown in the employment records of the Company, or in each case at such other address as such party shall have theretofore designated by written notice given to the other party.

16. Entirety and Modification. This Agreement contains the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes any and all prior agreements, whether written or oral, between such parties relating to such subject matter. No modification, alteration, amendment or supplement to this Agreement shall be valid or effective unless the same is in writing and signed by the party against whom it is sought to be enforced.

17. Severability. If any provision of this Agreement is held to be unenforceable, this Agreement shall be considered divisible, and such provision shall be deemed inoperative to the extent it is unenforceable, and in all other respects this Agreement shall remain in full force and effect; provided, however, that if any such provision may be made enforceable by limitation thereof, then such provision shall be deemed to be so limited and shall be enforceable to the maximum extent permitted by applicable law.

18. Gender. Words used in this Agreement that refer to Optionee and denote the male gender shall also be deemed to include the female gender or the neuter gender when appropriate.

19. Headings. The headings of the various sections and subsections of this Agreement have been inserted for convenient reference only and shall not be construed to enlarge, diminish or otherwise change the express provisions hereof.

20. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE (REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE DELAWARE PRINCIPLES OF CONFLICTS OF LAW).
