To effect a full and complete release as described above, Employee expressly waives and relinquishes all rights and benefits of section 1542 of the Civil Code of the State of California, and does so understanding and acknowledging the significance and consequence of specifically waiving section 1542. Section 1542 of the California Civil Code states:

A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.

Thus, notwithstanding the provisions of section 1542, and to implement a full and complete release of all claims, Employee expressly acknowledges this Agreement and Release is intended to include in its effect, without limitation, all causes of action or claims Employee does not know or suspect to exist in [his/her] favor at the time of signing this Agreement and Release, and that this Agreement and Release contemplates the extinguishment of any such causes of action or claims. Employee warrants [s/he] has read this Agreement and Release, including this waiver of California Civil Code section 1542, and has consulted counsel about this Agreement and Release and specifically about this waiver of section 1542, and that [s/he] understands this Agreement and Release and the section 1542 waiver, and so Employee freely and knowingly enters into this Agreement and Release. Employee acknowledges [s/he] may later discover facts different from or in addition to those [s/he] knows or believes to be true regarding the matters released or described in this Agreement and Release, and even so Employee agrees this release shall remain effective in all respects notwithstanding any later discovery of any different or additional facts. Employee assumes any and all risk of any mistake in connection with the true facts involved in the matters, disputes, or controversies described in this Agreement or with regard to any facts now unknown to Employee relating to those matters.

8. Affirmations. Employee affirms that [he/she] has not filed, caused to be filed, or presently is a party to any claim, complaint, or action against Employer in any forum or form. Employee further affirms that [he/she] has been paid and/or has received all leave (paid or unpaid), compensation, wages, bonuses, commissions, and/or benefits to which [he/she] may be entitled and that no other leave (paid or unpaid), compensation, wages, bonuses, commissions

and/or benefits are due to [him/her], except as provided in this Agreement and General Release. Employee furthermore affirms that [he/she] has no known workplace injuries or occupational diseases and has been provided and/or has not been denied any leave requested under the Family and Medical Leave Act.

11. Confidentiality. Each party agrees not to disclose any information regarding the existence or substance of this Agreement and General Release, except to [his/her] spouse, tax advisor, and an attorney with whom Employee chooses to consult regarding [his/her] consideration of this Agreement and General Release, except to the extent required by law.

12. Governing Law and Interpretation. This Agreement and General Release shall be governed and conformed in accordance with the laws of the state in which Employee was employed at the time of [his/her] last day of employment without regard to its conflict of laws provision.

13. Nonadmission of Wrongdoing. The parties agree that neither this Agreement and General Release nor the furnishing of the consideration for this Release shall be deemed or construed at anytime for any purpose as an admission by Employer of any liability or unlawful conduct of any kind.
