Employment Agreement between Robert N. Martin and the Company, dated as of July 12, 2024

I timely received this Notice and a copy of the Employment Agreement (the “Agreement”) on June 5th, 2024, at least fourteen (14) days before the earlier of either:

I acknowledge and understand that the Agreement, in Paragraphs 6(a) and 6(b) contains a confidentiality provision, as well as covenants not to solicit, which could restrict my options for subsequent employment following separation from employment with the company.

I further acknowledge that I have read the contents of this Notice, this Notice has been provided to me in the language in which I communicate with the company, and I understand the contents of this Notice. I may request an additional copy of the Agreement once every calendar year.

THIS EMPLOYMENT AGREEMENT (this “Agreement”) is by and between M.D.C. Holdings, Inc. (the “Company”) and Robert N. Martin (“Executive”). Together, the Company and Executive are referred to herein as the “Parties” and individually as a “Party”. Capitalized terms used and not otherwise defined in this Agreement shall have the meaning set forth in the Merger Agreement (as defined below).

WHEREAS, Executive has continuously worked for the Company since July 2002;

WHEREAS, the Company has completed a merger pursuant to that certain Agreement and Plan of Merger, dated as of January 17, 2024 (as amended, modified, supplemented or restated from time to time, the “Merger Agreement”), effective as of April 19, 2024, by and among Parent, Merger Sub, the Company and, solely for certain sections of the Merger Agreement, the Guarantor;

WHEREAS, the Company desires to continue to employ Executive, and Executive desires to accept such employment, pursuant to the terms and conditions set forth in this Agreement, effective as of July 12th (the “Effective Date”).

In consideration of Executive’s past, present and future performance of services for the Company and in consideration of the mutual promises and agreements hereinafter set forth, the Company and Executive agree as follows:

1.    Employment and Duties.

(a)    The Company will employ Executive, and Executive will be employed by the Company, as the Senior Vice President and Chief Financial Officer of the Company, which Executives agrees and acknowledges is a policy-making executive position, at the Company’s headquarters in Denver, Colorado (or such other location as the Parties may agree) for the term of this Agreement. In this capacity, Executive will continue his leadership role at the Company with active involvement in the Company’s finances, operations, and continue to assist in setting the strategic direction for the Company and perform such other services, consistent with his office, as from time to time are assigned by the applicable designee of Parent (the “Parent Designee”), devoting such time and effort to manage, operate and direct the activities of the Company and perform all of the functions of the offices held by him, in each case, as directed by the Parent Designee from time to time; provided, however, that Executive may also engage in other activities (subject to Section 6(b) below) consistent with his prior practices while employed by the Company, so long as such activities do not adversely affect the performance by Executive of his duties and responsibilities hereunder.

2. Term. The term of Executive’s employment hereunder will commence on the Effective Date and end on December 31, 2025 (the “Initial Term”); provided, however, that the Initial

Term will automatically renew for a successive one-year period, and will thereafter automatically renew for successive one-year periods (each, an “Additional Term”) unless Parent gives written notice to Executive of its intent to terminate this Agreement at the end of the then current term, such notice to be given at least sixty days prior to the expiration of the Initial Term or any Additional Term (the Initial Term and any and all Additional Terms are hereinafter collectively referred to as the “Employment Term”).

(a)     Base Salary. For calendar years 2024 and 2025, the Company will pay Executive a base salary of not less than $850,000 per year (the “Base Salary”), payable in accordance with the Company’s standard payroll practices less applicable deductions and withholdings. For each calendar year during the Employment Term beginning with 2026, if any, Executive will be eligible for periodic review of his Base Salary under the Company’s normal policies and procedures for executive salary increases. Executive’s Base Salary for any Additional Term may not be reduced below Executive’s Base Salary for the prior year without the consent of both Parties.

(b)    Annual and Long-Term Incentive Compensation.

i.    Target Award. For each of the calendar years 2024 and 2025, Executive will be eligible to earn a target award of $3,400,000 (“Target Award”), with a minimum annual guaranteed award equal to 50% of the Target Award (“Minimum Target Award”) and a maximum annual award equal to 200% of the Target Award (“Maximum Target Award”), as further described in the attached Exhibit A, which is incorporated herein by reference. Exhibit A may be amended from time to time by mutual agreement of the Parties without the need for a formal amendment to this Agreement. Except as otherwise set forth herein, any guaranteed and any earned additional target award will be paid no later than March 15th of the year immediately following the year to which the applicable annual award relates. With respect to each calendar year during the Employment Term beginning with 2026, if any, such annual guaranteed award will be determined by the Parties after engaging in good faith discussion regarding the annual bonus program to be established for such year(s), with the minimum guaranteed award not less than the Target Award, the Minimum Target Award or the Maximum Target Award achieved the prior calendar year.

ii.    Special Bonus. The Parent Designee may grant a special bonus at any time. Any earned special bonus will be paid no later than March 15th of the year immediately following the year to which the special bonus relates.

iii.    Long-Term Incentive Compensation. Executive is eligible to participate in the Company’s Long Term Incentive Plan, with an intended effective date of January 1, 2025, as it may be amended, and any successor of supplementary compensation and incentive plans or programs established by the Company (the “LTIP”).

The annual payments Executive is eligible to receive pursuant to Section 3(b)(i) and (ii) and Exhibit A are referred to herein as the “Annual Incentive Compensation” for the year to which they are attributable, regardless of the year in which they are paid. Except as otherwise set forth herein or as otherwise established by the Parent Designee, because the Annual Incentive Compensation is intended to reward performance during and encourage retention throughout the entire applicable calendar year, in order to earn any Annual Incentive Compensation for a given calendar year, Executive must remain employed by the Company through December 31st of such calendar year.

The payments Executive is entitled to receive pursuant to Section 3(b)(iii) are referred to herein as “Long-Term Incentive Compensation” or “LTIP Compensation”. LTIP Compensation awards are deemed earned if (1) Executive is employed on the last day of the applicable performance period, or (2) the award is otherwise fully vested, and (3) the award will be paid no later than March 15th of the year immediate following the year in which the applicable performance period expired, or (4) the award will be paid no later than March 15th of the year immediately following the date the award is fully vested.

(c)     Group Health Coverage. The Company will make available group medical, dental and vision insurance coverage (together, “Group Health Coverage”) for Executive and Executive’s spouse and dependents during the Employment Term. Executive’s Group Health Coverage will terminate upon Executive’s termination of employment (or if earlier, upon an otherwise qualifying event under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”)), and Executive will have the option to elect continuation coverage to the fullest extent such COBRA coverage is available to Executive and Executive’s spouse and dependents.

(d)     Expense Reimbursement. The Company promptly will pay, or reimburse Executive for, all ordinary and necessary business expenses incurred by him during the Employment Term in connection with the performance of his duties hereunder, including but not limited to, expenses and dues associated with Executive’s involvement with professional and industry organizations.

(e)     Other Benefits Plans, Fringe Benefits and Vacations. Subject to the terms therein, Executive is eligible to participate in each of the Company’s employee benefit plans, policies or arrangements and any such plans, policies or arrangements that the Company may maintain or establish during the Employment Term, and receive all fringe benefits and vacations for which his position makes him eligible in accordance with the Company’s policies and the terms and provisions of such plans, policies or arrangements including, but not limited to, the following:

(i)    If Executive should become disabled (short of becoming “Totally Disabled” as defined below) during the Employment Term, the Company will provide to Executive (whether through insurance or otherwise) disability benefits in an amount such that the after-tax amount per year received by Executive is equal to the after-tax amount of Executive’s Base Salary in effect for the year in which Executive becomes disabled. Such disability benefit will be payable monthly, until the earlier of (1) the end of Executive’s disability prior to his

becoming Totally Disabled or (2) Executive’s termination of employment. For purposes of this Agreement, Executive will be “Totally Disabled” if he is physically or mentally incapacitated so as to render him incapable of performing his usual and customary duties for a period expected to last not less than twelve consecutive months during which he receives income replacement benefits from a Company-provided health and accident plan for at least twelve months. Executive’s receipt of Social Security disability benefits will be deemed conclusive evidence of Total Disability for purposes of this Agreement; provided, however, that in the absence of his receipt of such Social Security benefits, the Company Board may, in its reasonable discretion, but based upon appropriate medical evidence, determine that Executive is Totally Disabled as provided in Treasury Regulation Section 1.409A3(i)(4).

(ii)     Each calendar year during the Employment Term, Executive is entitled to vacation (“PTO”) of not less than six weeks, in addition to standard paid Company holidays. Executive’s PTO accrual is capped at six weeks, and once reaching this cap Executive will not accrue additional PTO until PTO is used such that Executive’s balance falls below the cap.

(iii)    Following the Effective Date, the Company will not terminate or change, in such a way as to affect adversely Executive’s rights or reduce his benefits under any Company benefit plan, program, policy or arrangement now in effect or which may hereafter be established and in which Executive is eligible to participate, including, without limitation, life insurance, Group Health Coverage and short- or long-term disability plans.

4. Termination.

(a)     General. The Company may terminate Executive’s employment for any reason or no reason, and Executive may terminate his employment for any reason or no reason; provided, however, that the Company may terminate Executive’s employment without Cause only upon sixty days’ advance notice (or payment in lieu thereof). For purposes of this Agreement, the following terms have the following meanings:

(i)     Accrued Benefits means (1) accrued but unpaid Base Salary through the Termination Date, payable within the time required by law; (2) any Annual Incentive Compensation earned but unpaid with respect to the year preceding the year in which the Termination Date occurs or as otherwise payable in accordance with the terms of the applicable arrangement, payable in accordance with Section 3(b); (3) reimbursement for any unreimbursed business expenses incurred through the Termination Date under Section 3(g), payable within thirty days following the Termination Date; (4) accrued but unused PTO under Section 3(h)(ii), payable in the time required by law; (5) a lump-sum payment, which represents an amount equal to twelve times the monthly Group Health Coverage for Executive, and Executive’s spouse and dependents under the Company’s group medical, dental and vision plans as of the Termination Date; (6) a tax gross up payment so that Executive will have no after-tax consequences with respect to the lump-sum payment described in (5); and (7) all other vested payments, benefits, or fringe benefits to which Executive is entitled as of the Termination Date, payable in accordance

with and under the terms of any applicable compensation arrangement or benefit, equity, or fringe benefit plan, program or grant.

(ii)     Cause means (1) Executive’s willful refusal to perform the material duties consistent with his position and which are reasonably required or requested of him hereunder (other than as a result of total or partial incapacity due to physical or mental illness) by the Parent Designee for thirty days after having received written notice of such refusal from the Parent Designee and having failed to commence to perform such duties within such period, (2) Executive’s commission of material acts of fraud, dishonesty or misrepresentation in the performance of his duties hereunder, (3) any final, non-appealable conviction of Executive for an act or acts on Executive’s part constituting a felony under the laws of the United States or any state thereof, or (4) any material uncured breach of the provisions of Sections 6(a) and 6(b) hereof which continues for thirty days after Executive has received written notice of such breach from the Company.

(iii) Termination Date means the date on which Executive’s employment hereunder terminates in accordance with this Agreement.

(iv) Termination Payment means a single lump sum cash payment payable within thirty days following the Termination Date equal to the sum of: (1) the aggregate Base Salary Executive would have earned had he remained employed through the remainder of the Initial Term (or, if the Termination occurs during an Additional Term, the aggregate Base Salary Executive would have earned had he remained employed through the remainder of such Additional Term); and (2) if the Termination Date occurs in 2024, the Target Award for 2024 and 2025; if the Termination Date occurs in 2025, the Target Award for 2025; and if the Termination Date occurs during any Additional Term, the target Annual Incentive Compensation for the year in which the Termination Date occurs. For the avoidance of doubt, there shall be no duplication of benefits between amounts contemplated under subclause (2) of this definition of Termination Payment and the amount contemplated under subclause (2) of the defined term Accrued Benefits.

(b)     Termination for Cause. In the event that Executive’s employment hereunder is terminated by the Company for Cause, Executive will receive only the Accrued Benefits.

(d)     Termination Without Cause. In the event that prior to the end of the Initial Term, Executive’s employment hereunder is terminated by the Company without Cause, Executive will receive the Accrued Benefits and the Termination Payment. In the event that Executive’s employment hereunder is terminated by the Company without Cause prior to the end of an Additional Term, Executive will receive the Accrued Benefits and the Termination Payment for the year of Executive’s Termination Date. In accordance with Section 4(a), the Company may terminate Executive’s employment without Cause only upon sixty days’ advance notice (or payment in lieu thereof). Accordingly, in the event the Company terminates Executive less than sixty days prior to the end of the calendar year, Executive will be deemed terminated in the following calendar year. For example, if the Company terminates Executive on December 15,

2026, Executive’s Termination Date will be deemed February 13, 2027. In this case, Executive will receive the Termination Payment for 2026 and for 2027.

(e)         Termination Due to Death, Presumed Death or Becoming Totally Disabled. In the event that, prior to the end of the Initial Term, Executive’s employment hereunder is terminated due to Executive’s death, presumed death or Executive becoming Totally Disabled, Executive, or Executive’s beneficiary or estate, as applicable, will receive the Accrued Benefits and the Termination Payment.

(f)      Release Requirement. Payments and benefits that become due to Executive pursuant to the terms and conditions of this Section 4, other than the Accrued Benefits, or payments that become due in accordance with Section 4(e) are contingent upon and subject to Executive’s execution and non-revocation of a release of claims, similar to the release of claims attached hereto as Exhibit B (the “Release”) with such Release becoming effective within sixty days following Executive’s Termination Date.

(a)     The Company will withhold all applicable federal, state, and local taxes, FICA (Social Security and Medicare), and workers’ compensation contributions and other amounts as may be required by law with respect to compensation payable to Executive pursuant to this Agreement.

(b)     Notwithstanding anything herein to the contrary, this Agreement is intended to be interpreted and applied so that the payment of the benefits set forth herein will either be exempt from, or in the alternative, comply with, the requirements of Code Section 409A. A termination of employment will not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment that are considered “nonqualified deferred compensation” under Section 409A unless such termination is also a “separation from service” within the meaning of Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “Termination Date” or like terms will mean “separation from service.” Notwithstanding any provision of this Agreement to the contrary, if Executive is a “specified employee” within the meaning of Section 409A on the date of his “separation from service,” any payments or arrangements due upon a termination of Executive’s employment under any arrangement that constitutes a “nonqualified deferral of compensation” within the meaning of Section 409A and which do not otherwise qualify under the exemptions under Treas. Regs. Section 1.409A-1 (including without limitation, the short-term deferral exemption or the permitted payments under Treas. Regs. Section 1.409A-1(b)(9)(iii)(A)), will be delayed and paid or provided on the earlier of (i) the date which is six months after Executive’s “separation from service” for any reason other than death or presumed death, or (ii) the date of Executive’s death or presumed death.

(c)     After his Termination Date, Executive will have no duties or responsibilities that are inconsistent with having a “separation from service” within the meaning

of Section 409A as of the Termination Date and, notwithstanding anything in the Agreement to the contrary, distributions upon termination of employment of nonqualified deferred compensation may only be made upon a “separation from service” as determined under Section 409A and such date will be the Termination Date for purposes of this Agreement. Each payment under this Agreement or otherwise will be treated as a separate payment for purposes of Section 409A. In no event may Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement which constitutes a “nonqualified deferral of compensation” within the meaning of Section 409A and to the extent an amount is payable within a time period, the time during which such amount is paid will be in the discretion of the Company.

(d)     All reimbursements and in-kind benefits provided under this Agreement will be made or provided in accordance with the requirements of Section 409A. To the extent that any reimbursements are taxable to Executive, such reimbursements will be paid to Executive on or before the last day of Executive’s taxable year following the taxable year in which the related expense was incurred. Reimbursements will not be subject to liquidation or exchange for another benefit and the amount of such reimbursements that Executive receives in one taxable year will not affect the amount of such reimbursements that Executive receives in any other taxable year.

(e)     This Section 5(e) shall be construed in accordance with Code Sections 280G and 4999, or any successor provisions thereto, and the guidance issued thereunder (collectively, “Section 280G”), and the terms “parachute payment” and “excess parachute payment” as used herein have the meanings ascribed to them under Section 280G.

(i)     If it shall be determined that the aggregate payments and benefits constituting parachute payments which, but for the operation of this provision, would become payable or distributable by the Company to or for the benefit of Executive, pursuant to this Agreement, any other agreement, or any benefit plan (collectively, the “Total Payments”), would result in any excess parachute payments becoming subject to the excise tax imposed by Code Section 4999, or any successor provision thereto, or any interest or penalties with respect to such excise tax (such excise tax, together with such interest and penalties, collectively, the “Excise Tax”), then the Total Payments shall be reduced to an amount equal to one dollar less than the amount which would cause the parachute payments to be subject to the Excise Tax; provided that the reduction contemplated by this Section 5(e) shall be applied only if the net after-tax benefit to Executive after such reduction would be greater than the net after-tax benefit to Executive without such reduction (notwithstanding the application of any Excise Tax on the unreduced Total Payments). For the avoidance of doubt, Executive shall be responsible for the payment of any Excise Tax arising from the Total Payments.

(ii)     The Company will reduce or eliminate the Total Payments by first reducing or eliminating any cash parachute payments that do not constitute deferred compensation within the meaning of Section 409A, then by reducing or eliminating any other parachute payments that do not constitute deferred compensation within the meaning of Section 409A, then by reducing or eliminating all other parachute payments that do constitute deferred

compensation within the meaning of Section 409A, beginning with those payments last to be paid, subject to and in accordance with all applicable requirements of Section 409A.

(iii)     Unless the Company and Executive otherwise agree in writing, all calculations and determinations necessary to effectuate this provision, including without limitation determinations as to whether a reduction in payments or benefits is required and the amount thereof, whether any item of compensation constitutes a parachute payment, the amount, if any, subject to the Excise Tax (including determinations as to whether any portion of the excess parachute payments constitutes reasonable compensation for services actually rendered, within the meaning of Code Section 280G(b)(4)(B)), and the present value of any parachute payment, shall be made, consistent with Section 280G, by Ernst & Young LLP (the “Advisors”). For this purpose, the Advisors may make reasonable assumptions and approximations; may rely on reasonable, good faith interpretations concerning the application of Section 280G; and may rely upon such other tax, legal, valuation or other specialists as they deem appropriate. Executive’s applicable federal, state, and local income taxes shall be computed at the highest applicable marginal rate, net of the maximum reduction, if any, in federal income taxes which could be obtained from a deduction of such state and local taxes. The Company and Executive agree to furnish the Advisors with such information and documents as the Advisors reasonably request to make such calculations and determinations as soon as practicable upon such request. The Company shall direct the Advisors to provide Executive with a written statement of its conclusions, setting forth the basis therefor, including detailed supporting calculations and copies of any written opinions or advice upon which such conclusions rely (the “Report”), within ten business days after their receipt of all required information and documents. Executive shall have five business days thereafter to notify the Advisors and the Company in writing of any reasonable and substantive objections to the Report. The Company shall direct the Advisors to promptly consider in good faith and respond to such objections and provide Executive a revised Report reflecting appropriate adjustments (unless the Advisors determine that no adjustments are necessary). The Advisors’ final calculations and determinations (as adjusted, if applicable) shall be conclusive and binding on all parties for all purposes. The Company shall bear all costs the Advisors may reasonably incur in connection with the process contemplated by this Section 5(e).

(g)    Notwithstanding anything in this Section 5, Executive will be responsible for the satisfaction of all taxes and penalties that may be imposed on him in connection with any payments made pursuant to this Agreement, and neither Parent, the Company nor any of their respective affiliates or successors shall have any obligation to reimburse, indemnify or otherwise hold Executive harmless from any or all such taxes or penalties, unless the taxes and/or penalties that are imposed on Executive are a result of the Company failing to properly collect, account for, deposit and report taxes in accordance with Section 5(a), in which case the Company has an obligation to reimburse, indemnify and otherwise hold Executive harmless from any or all such taxes or penalties.

6. Covenants.

(a)     Confidentiality. Executive agrees that, during the Employment Term and for a period of twelve months beginning on the last day of the Employment Term, he will not

divulge, furnish or make accessible to any person, corporation, partnership, trust or other organization or entity (other than Executive’s legal, tax and other advisors, to the extent they need to know such confidential information to advise Executive), any information, trade secrets, technical data or know-how relating to the business, business practices, methods, attorney-client communications, pending or contemplated acquisitions or other transactions, products, processes, equipment or any confidential or secret aspect of the business of the Company without the prior written consent of the Company, unless such information has become public knowledge or has become known generally to competitors of the Company through sources other than Executive. This prohibition does not apply to information which arises from Executive’s general training, knowledge, skill, or experience, whether gained on the job, or otherwise; is readily ascertainable or generally known to the public; or Executive otherwise has a right to disclose pursuant to legally protected conduct.

(b)     Non-Solicitation.

i.    Beginning on the date hereof and for a period of twelve months beginning on (1) the last day of the Employment Term or (2) a termination of Executive’s employment by the Company for Cause (the “Non-Solicit Period”), Executive will not, and will cause his affiliates not to, directly or indirectly, through or in association with any third party (x)  solicit any customer, supplier, distributor, developer, service provider, licensor, or licensee or other material business relation of the Company, or (y) attempt to do any of the foregoing, either for Executive’s own purposes or for any other third party.

ii.    During the Non-Solicit Period, Executive will not, and will cause his or her affiliates not to, directly or indirectly, through or in association with any third party (1) solicit, induce, recruit, or encourage any employees or independent contractors of or consultants to the Company to terminate their relationship with the Company or (2) attempt to do any of the foregoing, either for Executive’s own purposes or for any other third party.

(c)    Remedy for Breach. Executive acknowledges that the provisions of this Section 6 are reasonable and necessary for the protection of the Company’s trade secrets and that the Company will be irrevocably damaged if such covenants are not specifically enforced. Accordingly, Executive agrees that, in addition to any other relief to which the Company may be entitled, the Company (or an applicable affiliate thereof) will be entitled to seek and obtain injunctive relief from a court of competent jurisdiction for the purposes of restraining Executive from any actual breach of such covenants without the requirement of posting a bond. If Executive violates any of the terms of the restrictive covenant obligations in this Agreement, such restrictions will automatically be extended by the period Executive was in violation of them.

(d)    Non-Disparagement. Executive hereby agrees that Executive will not, at any time, make any statement intended to disparage, defame or otherwise malign the goodwill or reputation of Parent, the Company or any of their respective stakeholders, officers or directors. The Parent and the Company hereby also agree that it will instruct its respective officers,

employees and directors to not, at any time, make any statement intended to disparage, defame or otherwise malign the goodwill or reputation of Executive.

(e)    Protected Activity. Notwithstanding any other provision of this Agreement, Executive will not be held criminally or civilly liable under any federal or state trade secret law for any disclosure of a trade secret that (A) is made: (1) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (2) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If Executive files a lawsuit for retaliation by the Company for reporting a suspected violation of law, Executive may disclose the Company’s trade secrets to Executive’s attorney and use the trade secret information in the court proceeding if Executive files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order. Nothing in this Agreement prohibits Executive (or Executive’s attorneys) from initiating communications directly with, or responding to any inquiry from, or providing testimony before, the Securities and Exchange Commission (“SEC”), Financial Industry Regulatory Authority (“FINRA”), any other self-regulatory organization or any other state or federal regulatory authority regarding this Agreement or its underlying facts or circumstances. In addition, nothing in this Agreement prohibits Executive from reporting possible violations of federal, state, or local law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the SEC, FINRA, the Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal, state, or local law or regulation. Executive is not required to contact the Company regarding the subject matter of any such communications before engaging in such communications. Further, nothing in this Agreement limits Executive’s ability to disclose or discuss, either orally or in writing, any alleged discriminatory or unfair employment practice, as set forth in C.R.S. § 24-34-402.

7. Miscellaneous.

(a)    Governing Law. This Agreement is governed by and construed in accordance with the laws of the State of Colorado applicable to agreements made and to be performed in that State, without giving effect to any choice of law rules or other conflicting provision or rule that would cause the laws of any jurisdiction to be applied; provided, however, that the following provisions shall be governed by the Federal Arbitration Act.

i.    Arbitration of Disputes. To the fullest extent permitted by applicable law, any dispute or controversy arising under or in connection with this Agreement will be settled exclusively by arbitration, in accordance with the rules of the American Arbitration Association for employment disputes as then in effect. For the avoidance of doubt, it is understood and agreed that this Agreement to arbitrate includes any and all claims and disputes, including, without limitation, as to arbitrability, with respect to Executive’s employment with the Company or the termination of such employment, including, without limitation, any claim for alleged discrimination, harassment, or retaliation under on the basis of race, sex, color, national origin, sexual orientation, age, religion, creed, marital status, veteran status, alienage, citizenship, disability or handicap, or any other legally protected status, and any

alleged violation of any federal, state, or other governmental law, statute or regulation, including, but not limited to, any alleged violation of Title VII of the Civil Rights Act of 1964, other civil rights statutes including, without limitation, 42 U.S.C. § 1981, 42 U.S.C. § 1982, and 42 U.S.C. § 1985, the Age Discrimination in Employment Act, the Americans with Disabilities Act, the Family and Medical Leave Act, the Worker Adjustment and Retraining Notification Act, the Employee Retirement Income Security Act, the Fair Labor Standards Act, the Occupational Safety and Health Act, the Immigration Reform and Control Act, the Sarbanes-Oxley Act, or any state or local law, statute or regulation, as such statutes, laws, and regulations are amended. Judgment may be entered on the arbitrator's award in any court having jurisdiction.

ii.    Procedures; Enforcement. The arbitration hearing will commence within ninety calendar days after the arbitrator is selected, unless Company and Executive mutually agree to extend this time period. The arbitration will take place in Denver County, Colorado. The arbitrator will have full power to give directions and make such orders as the arbitrator deems just, and to award all remedies that would be available in court. Nonetheless, the arbitrator explicitly will not have the authority, power, or right to alter, change, amend, modify, add, or subtract from any provision of this Agreement. The arbitrator will issue a written decision that sets forth the essential findings and conclusions upon which the arbitrator’s award or decision is based within thirty days after the conclusion of the arbitration hearing. The award rendered by the arbitrator will be final and binding (absent fraud or manifest error), and any arbitration award may be enforced by judgment entered or vacated in any court of competent jurisdiction.

iii.    Cost Allocation. In the event of any contest or dispute relating to this Agreement or the termination of Executive’s employment hereunder, the Parties will bear its own costs and expenses.

This Agreement may not be amended except by a written agreement signed by the Parties.

(e)     Waiver. The failure of a Party to insist upon strict adherence to any term of this Agreement on any occasion will not be considered a waiver thereof or deprive that Party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement.

(f)     Assignment. Except as otherwise provided in this paragraph, this Agreement will inure to the benefit of and be binding upon the Parties and their respective heirs, representatives, successors and assigns. This Agreement is not assignable by Executive, and is assignable by the Company only to any corporation or other entity resulting from the reorganization, merger or consolidation of the Company with any other corporation or entity or
