Plan Document Acknowledgment. By accepting the Option, the Optionee acknowledges that he or she has received copies of the Plan, has reviewed the Plan and the Agreement in their entirety and fully understands and accepts all provisions of the Plan and the Agreement.
In addition, by signing the Agreement, the Optionee further acknowledges that he or she has read and specifically and expressly approves the terms and conditions in paragraph 9 of the Agreement, in which the following is clearly described and established: (i) participation in the Plan does not constitute an acquired right; (ii) the Plan and participation in the Plan is offered by the Company on a wholly discretionary basis; (iii) participation in the Plan is voluntary; and (iv) the Company and its parent, subsidiaries and affiliates are not responsible for any decrease in the value of the shares underlying the Option.
Finally, the Optionee hereby declares that he or she does do not reserve any action or right to bring any claim against the Company for any compensation or damages as a result of participation in the Plan and therefore grants a full and broad release to the Employer and the Company and its parent, subsidiaries and affiliates with respect to any claim that may arise under the Plan.
