Any Options outstanding and not exercised within such one (1) month period shall become void.

Until such time as the Company's membership interests or stock is publicly traded or until such time that the board of managers amend this agreement, the Employee and Consultant agrees that all interests purchased by him/her, his/her estate or beneficiary under the Plan are 5 acquired for investment and not for distribution. The Employee and Consultant also agrees that any notice of exercise of the Option shall become accompanied by a written representation, signed by the Employee and/or Consultant, to that effect. If the Company ever commences a public offering of its securities, it is likely the Company's membership interests will be reclassified into shares of common stock. Such reclassification will be structured so that Employee's and/or Consultant's percentage of ownership or interest in the Company is not diluted. Employees and Consultants also understand that should the Company's membership interests or stock become publicly traded, there may be certain restrictions placed on the sale of interests held by Employees and/or Consultants, and other insiders, for a period of up to one year or longer, as determined by the underwriter of any such transaction. Employees and Consultants further understand that neither the Company, its officers, nor its board of managers can guarantee or promise that the Company's membership interests or stock will ever be registered or publicly traded. Additionally, there may never be a market for any such Company membership interests or stock, and that such Company membership interests or stock may be unmarketable. The Company shall have no duty or obligation to repurchase any or all of its outstanding Class B membership interests. CONTINUED SERVICE Employees. Employee, in consideration of the granting of Options to --------- him/her, agrees that he/she will continue to render services to the Company except as he/she may be prevented from doing so by death, disability, retirement, or termination. Nothing in the Plan shall be deemed to confer to an Employee any guaranteed right to continue to be employed by the Company, or interfere in any way with the right of the Company to terminate his/her employment, as provided by the by- laws of the Company or as provided by law. Consultants. Nothing in the Plan shall be deemed to confer to a Consultant ----------- any guaranteed right to continue to be under contract by the Company, or interfere in any way with the right of the Company to terminate his/her contract, as provided by the by-laws of the Company or as provided by law. TAX EFFECTS Employees and Consultants understand that there may be both federal and state income tax consequences associated with the exercise of the Options granted by the Plan, including withholding requirements. Employees acknowledge that they have conferred with their 6 respective counsel regarding any and all such tax consequences, and that in no event shall Company be liable or responsible for any such tax liability. GOVERNING LAW The Plan shall be governed by the law of the State of New York. IN WITNESS WHEREOF, Corporation has caused this agreement to be executed on the date of first above written.
