General Release. In exchange for retaining a retention payment of $X (the “Retention Bonus”), I, NAME, completely RELEASE AND FOREVER DISCHARGE the Company and each of its past or present subsidiaries and affiliates, its and their past or present officers, directors, members, agents, attorneys, representatives, shareholders or employees (collectively, the “Released Parties”), acting in any capacity whatsoever, of and from any and all manner of actions and causes of actions, suits, debts, claims and demands whatsoever in law or in equity, whether known or unknown, which I ever had, now have, or hereafter may have, or which my heirs, executors or administrators hereafter may have against the Released Parties, by reason of any matter, cause or thing whatsoever from the beginning of my employment with the Company through the date of this release.

Extent of Release. This release includes all claims, whether known or unknown, which I may have that relate in any way either to the time of my employment or my termination of employment, through the date I sign this release, except the claims mentioned in paragraph 3 (Exceptions to Release). Some of the types of claims, which I am releasing, although there also may be others not specifically listed here, are all claims under local, state or federal law that relate to:

Discrimination on the basis of sex, race, color, national origin, religion, disability, sexual orientation or veteran status;

Wrongful Discharge (including retaliatory discharge) or any other possible restrictions on the Company’s ability to terminate its employees at will, including, but not limited to, (i) violation of public policy, (ii) breach of any express or implied covenant of the employment contract, and (iii) breach of any covenant of good faith and fair dealing;

Discrimination on the basis of age, including claims under the Age Discrimination in Employment Act (the “ADEA”), 29 U.S.C. § 621 et seq., the Older Workers Benefit Protection Act; 29 U.S.C. section 626(f) (the “OWBPA”) and any applicable state or local law prohibiting age discrimination; and

Civil actions relating to negligence, compensation, defamation, invasion of privacy, fraud, misrepresentation, breach of contract, denial of leave or other terms and conditions of employment, or infliction of emotional or mental distress.

Exceptions to Release. The only claims that this release does not include, are claims related to:

The consideration offered for this release;

Any claims that controlling law clearly states may not be released by settlement; and

To be 45 days (and subject to other modifications) if the termination is a “group termination”.

Any claims that may arise after the date this release is signed; and

Any claim or right relating to indemnification, exculpation, duty to defend or hold harmless provisions owed to me by the Company by virtue of any employment agreement, organizational document of the Company, policy of the Company or through any other source. By executing this Release, I in no way waive or give up any rights I may have and relating to the foregoing obligations of the Company,

21-Day Consideration Period. I understand that I have twenty-one (21) days to consider this release and consult an attorney if I wish to do so. However, I knowingly and voluntarily waive the remainder of the 21-day consideration period, if any, following the date I signed this release below. I have not been asked by the Company to shorten the time period for consideration of whether to sign this release. The Company has not threatened to withdraw or alter the benefits due me prior to the expiration of the 21-day period nor has the Company provided different terms to me because I have decided to sign the release prior to the expiration of the 21-day consideration period.

Revocation Period. I understand that I have a seven-day period after signing this release in which to revoke or rescind my release, by informing the Company’s Vice President, Human Resources, in writing of my decision to revoke or rescind, and that this release will not be effective or enforceable until the end of the seven-day period. The lapse of the repayment obligation associated with the Retention Bonus in exchange for this release will not occur until the eighth day after I sign this release.

Return of Property. I understand and agree to return all confidential information, computer hardware or software, files, papers, memoranda, correspondence, customer lists, financial data, credit cards, keys, tape recordings, pictures, and security access cards, and any other items of any nature which were or are the property of the Company. I further agree not to retain any copies of any such property in my possession or under my control.

Non-disparagement. I agree not to disparage or in any way criticize the Company and/or its officers, managers, supervisors, employees, investors, agents, advisors, products, services or technology. However, I understand that nothing contained in this Paragraph is intended to prevent me from testifying truthfully in any legal proceeding.

Confidentiality. I agree to maintain the confidentiality of this release and will not disclose in any fashion this release, the amount of the benefits I receive, and/or the substance or content of discussions involved in this release to any person other than my attorneys, accountants, and tax advisors as required by appropriate taxing authorities, or otherwise as required by law. Notwithstanding anything to the contrary contained herein, nothing in this release prohibits me from reporting possible violations of federal law or regulation to any United States governmental agency or entity in accordance with the provisions of and rules promulgated under Section 21F of the Securities Exchange Act of 1934 or Section 806 of the Sarbanes-Oxley Act of 2002, or any other whistleblower protection provisions of state or federal law or regulation (including the right to receive an award for information provided to any such government agencies). Furthermore, in accordance with 18 U.S.C. § 1833, notwithstanding anything to the contrary in this release: (a) I shall not be in breach of this release, and shall not be held criminally or civilly liable under any federal or state trade secret law (i) for the disclosure of a trade secret that is made in confidence to a federal, state, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) for the disclosure of a trade secret that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal; and (b) if I file a lawsuit for retaliation by the Company for reporting a suspected violation of law, I may disclose the trade secret to my attorney, and may use the trade secret information in the court proceeding, if I file any document containing the trade secret under seal, and do not disclose the trade secret, except pursuant to court order.

Binding Agreement. I understand that following the seven-day revocation period, this release will be final and binding. I promise that I will not pursue any claim that I have settled by this release. If I break this promise, I agree to pay all of the Company’s costs and expenses (including reasonable attorneys’ fees) related to the defense of any claims other than claims under the OWBPA and the ADEA. I understand, also, that if I pursue a claim against the Company under the OWBPA and/or the ADEA, a court has the discretion to determine whether the Company is entitled to restitution, recoupment, or set off (hereinafter “reduction”) against a monetary award obtained by me in the court proceeding. A reduction never can exceed the amount I recover, or the consideration I received for signing this release, whichever is less. I also recognize that the Company may be entitled to recover costs and attorneys’ fees incurred by the Company as specifically authorized under applicable law.

Protected Rights. Notwithstanding the other provisions of this release, I understand that nothing contained in this release limits my ability to file a charge or complaint with the Equal Employment Opportunity Commission (or similar state or local agency) or any other federal, state or local governmental agency or commission. I further understand that this release does not limit my ability to communicate with any government agencies or otherwise participate in any investigation or proceeding that may be conducted by any government agencies (including, but not limited to, the U.S. Securities and Exchange Commission, the U.S. Commodity Futures Trading Commission, or the U.S. Department of Justice), including providing documents or other information, without notice to the Company. To the extent a charge or complaint is filed by me or on my behalf, I waive all rights to receive any monetary recovery from the Company as a result of such action. However, this release does not limit my right to receive an award for information provided to any government agencies.

General Provisions. The validity of this release shall be construed under Texas law. WITH RESPECT TO ANY SUIT, ACTION, OR OTHER PROCEEDING ARISING FROM (OR RELATING TO) THIS RELEASE OR MY EMPLOYMENT WITH THE COMPANY, I IRREVOCABLY AGREE TO THE EXCLUSIVE PERSONAL JURISDICTION AND VENUE OF ANY UNITED STATES FEDERAL OR TEXAS STATE COURT WITHIN TRAVIS COUNTY, TEXAS. This release constitutes the complete and total agreement between the Company and me. I represent that I am not relying on any other agreements or oral representations not fully expressed in this agreement. I agree that this release shall not be modified, altered, or discharged except by written instrument signed by an authorized Company representative and me. The headings in this release are for reference only, and shall not in any way affect the meaning or interpretation of this release. I further agree that this release may be used as evidence in a subsequent proceeding in which the Company or I allege a breach of this release or as a complete defense to any lawsuit. Other than this exception, I agree that this release will not be introduced as evidence in any legal or administrative proceeding or in any lawsuit. I agree that should any part of this release be found to be void or unenforceable by a court of competent jurisdiction, that determination will not affect the remainder of this release.
