1

attorneys, successors and assigns (individually and collectively “Releasees”) from any and all liabilities, causes of action, debts, claims and demands, both in law and in equity, known or unknown, fixed or contingent, which Mr. Lucki has, may have or claims or claimed to have, based upon or in any way related to his employment or resignation from employment with the Company arising up to and including his Resignation Date or the execution date of this Agreement, whichever is later.  This includes but is not limited to claims for damages, wages or other relief arising under federal, state, or local laws prohibiting employment discrimination and other unfair or unlawful treatment, including, without limitation, Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, 42 U.S.C. Section 1981, the Age Discrimination in Employment Act of 1967 (“ADEA”), the Americans with Disabilities Act Amendments Act of 2008 (“ADAAA”), the Employee Retirement Income Security Act of 1974 (“ERISA”), the Lily Ledbetter Fair Pay Act of 2009, the Family Medical Leave Act of 2008 (“FMLA”), the Genetic Information Nondiscrimination Act of 2008 (“GINA”), the Equal Pay Act of 1963, as amended, 29 U.S.C. § 206(d)(1)-(4), the Rehabilitation Act of 1974, 29 U.S.C. § 701, et seq., the Health Insurance Portability and Accountability Act of 1996, as amended, § 46 U.S.C. § 300gg, et seq., the Consolidated Omnibus Budget Reconciliation Act, 29 U.S.C. § 1161, et seq., Executive Order 11246, whistleblower claims, the Colorado Anti-Discrimination Act, the Colorado Wage Claim Act, Colorado Wage Equality Regardless of Sex Act, Colorado’s Minimum Wage Orders, Colorado Labor Peace Act, Colorado’s Minimum Wages of Workers Act (all as amended), and any claims based on any state statute or law (including, by way of example only, any state statute or act prohibiting employment discrimination or harassment), contract (including, by way of example only, the Company’s policies, practices and/or plans), covenant of good faith and fair dealing, public policy, tort (by way of example only, defamation, intentional or negligent infliction of emotional distress, misrepresentation, interference with contract, wrongful, retaliatory and/or constructive discharge) or other theories, as well as any claim for attorney’s fees and/or costs or other expenses or fees.  Mr. Lucki expressly acknowledges that the Resignation Benefits hereunder are intended to and do fully compensate him for any and all of his possible claims up to and including his Resignation Date or the date he signs this Agreement, whichever is later, including, without limitation, those for alleged emotional or physical distress, stress, pain and suffering, and upset or injury, together with medical care of any sort associated with such claims.  Mr. Lucki acknowledges and agrees that he has suffered no workplace injury which would give rise to a claim under any worker’s compensation statute or, if he has, that he has been fully compensated hereunder and is entitled to no further relief of any kind (monetary or otherwise).  For purposes of this Agreement, “Employee Benefit Plan” means any employee benefit plan, as defined in ERISA Section 3(3), sponsored, or contributed to, by the Company or any Releasee.  Nothing herein prohibits Mr. Lucki from filing a charge of discrimination with the Equal Employment Opportunity Commission (“EEOC”) or any state fair employment practices agency, or from participating in any investigation of a charge of discrimination by the EEOC or any state fair employment practices agency.

5.              This Agreement, including all discussions concerning its subject matter between the parties, represents an amicable settlement and compromise of all allegations, claims and matters that Mr. Lucki has or claims to have in connection with his employment and/or resignation from employment with the Company.  By entering into this Agreement, no party hereto admits any impropriety, wrongdoing, or liability of any kind whatsoever and, on the contrary, expressly denies same.

6.              Mr. Lucki promises that he has not filed a lawsuit in any state or federal court relating to the matters released herein against any of the Releasees, and has not filed or initiated a charge or administrative complaint alleging employment discrimination with the EEOC or any state fair employment practices agency against any of the Releasees, and further that he has not assigned or transferred to any person any portion of any claim which is released and waived by this Agreement.  While nothing in this Agreement prevents Mr. Lucki from filing a federal or state administrative charge, if such a federal or state administrative charge is filed or an agency investigation undertaken, he acknowledges that he has already received full monetary and other relief hereunder and is entitled to no further relief of any kind (monetary or otherwise).  Mr. Lucki shall pay his own costs, expenses and attorney’s fees incurred in association with this matter and shall not seek any compensation or any reimbursement for his costs, expenses and attorney’s fees from any of the Releasees.

7.             The release and waiver above does not affect any entitlement of Mr. Lucki to vested benefits, if any, under the Company’s 401(k) plan or other vested benefits under any other Employee Benefit Plan, if any.  Any

2

vested but unexercised stock options held by Mr. Lucki must be exercised within the time period required by the Employee Ownership Program.  Mr. Lucki acknowledges that he can obtain information about such vested but unexercised stock from the Employee Ownership group (O@ch2m.com or (720) 286-2753).  The Company and Mr. Lucki do not, by executing this Agreement, release any claims with respect to the enforcement of the Agreement.

8.              Mr. Lucki agrees that no lawsuit (federal or state) shall be filed by him against any of the Releasees based upon any claim released above.  In the event Mr. Lucki breaches this promise by filing such a lawsuit, he may be responsible for paying the attorneys’ fees and costs incurred by any and/or all of the Releasees in defending against the lawsuit if the lawsuit is brought in bad faith, or is frivolous and groundless, or if authorized by state or federal law.  The foregoing does not nullify the waiver and release by Mr. Lucki nor limit any of the Releasees’ rights and remedies.

9.              In the event a particular provision of the Agreement is declared invalid or unenforceable, the remaining provisions of the Agreement will continue in full force and effect.  This Agreement shall be construed in all respects as if such invalid or unenforceable provisions were omitted.

10.       Older Workers Benefit Protection Act of 1990 (OWBPA).   In compliance with the OWBPA, and by virtue of this Agreement, Mr. Lucki has been advised of the legal requirements of the Act, and fully incorporates by reference the legal requirements into this Agreement as follows:
