It shall be a condition to the transfer of this Option that any transferee hereof deliver to Company its written agreement to accept and be bound by all of the representations, terms and conditions of this Option.

(b) The stock certificates of Company that will evidence the Purchased Common Stock may be imprinted with a restrictive legend in substantially the following form:

Except as otherwise set forth herein, Company has not agreed to comply with any exemption from registration under the Securities Act or the State Acts for the resale of such Common Stock. Hence, it is the understanding of Optionee that by virtue of the provisions of certain rules respecting “restricted securities” promulgated by the U.S. Securities and Exchange Commission, all or part of the Purchased Common Stock may be required to be held indefinitely, unless and until registered under the Securities Act and the State Acts, or unless an exemption from such registration is available (in which case Optionee may still be limited as to the amount of such Common Stock that may be sold).

7. Representations.

(a) Risk Factors. Optionee understands and acknowledges that (i) this Option and the Purchased Common Stock are unregistered, restricted securities and are not readily marketable and (ii) there is a significant degree of risk in investing in the Common Stock.

(b) Knowledge and Experience; Financial Capability and Net Worth. Optionee has (i) such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risk of the investment in the Common Stock, (ii) has determined that such investment is suitable for Optionee in view of its financial circumstances and available investment opportunities; and (iii) no need for liquidity of the investment and no reason to anticipate any change in Optionee’s financial circumstances which may cause or require any sale, transfer or other distribution of the Purchased Common Stock.

(c) Information. Optionee agrees that it shall be its responsibility to request such information with respect to Company as it and its advisors deem appropriate to evaluate the risks and merits of investment in the Purchased Common Stock at the time that Optionee exercises this Option.

8. Remedies. The Company stipulates that the remedies at law of Optionee in the event of any default or threatened default by Company in the performance of or compliance with any of the terms of this Option are not and will not be adequate and that, without limiting any other remedy available at law, such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof. The rights and remedies of Optionee are cumulative and not exclusive of any rights or remedies which Optionee might otherwise have.

9. Survival. The various rights and obligations of Optionee hereof as set forth herein shall survive the exercise of this Option at any time or from time to time and the surrender of this Option.

10. Change; Waiver. Neither this Option nor any term hereof may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought. No failure or delay of Optionee in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.

11. Governing law. The execution, effectiveness, construction, performance, amendment and termination of this Option and the resolution of disputes hereunder shall be governed under the laws of Nevada.

12. Confidentiality. The parties acknowledge that the existence and the terms of this Option and any oral or written information exchanged between the parties in connection with the preparation and performance this Option are regarded as confidential information. Each party shall maintain confidentiality of all such confidential information, and without obtaining the written consent of the other party, it shall not disclose any relevant confidential information to any third parties, except for the information that: (a) is or will be in the public domain (other than through the receiving party's unauthorized disclosure); (b) is under the obligation to be disclosed pursuant to the applicable laws or regulations, rules of any stock exchange, or orders of the court or other government authorities; or (c) is required to be disclosed by any party to its shareholders, investors, legal counsels or financial advisors regarding the transaction contemplated hereunder, provided that such shareholders, investors, legal counsels or financial advisors shall be bound by the confidentiality obligations similar to those set forth in this Section. This Section shall survive the termination of this Option for any reason.

13. Severability. In the event that one or several of the provisions of this Option are found to be invalid, illegal or unenforceable in any aspect in accordance with any laws or regulations, the validity, legality or enforceability of the remaining provisions of this Option shall not be affected or compromised in any respect. The parties shall strive in good faith to replace such invalid, illegal or unenforceable provisions with effective provisions that accomplish to the greatest extent permitted by law and the intentions of the parties, and the economic effect of such effective provisions shall be as close as possible to the economic effect of those invalid, illegal or unenforceable provisions.

14. Successors. This Option shall be binding on and shall inure to the interest of the respective successors of the parties and the permitted assigns of such parties.
