Poor performance shall not by itself constitute Cause. Your actions or inactions based upon the direction of the Board, General Partner, or the Chief Executive Officer of the Company shall not constitute Cause. Cause shall be determined in the reasonable discretion of the Company. No action or inaction shall be treated as willful unless done or not done in bad faith and without a reasonable belief that such action or inaction was in the best interests of the Company or its affiliates.

This offer is for continued “at-will” employment and is not to be interpreted as a guarantee of employment or duties expressed or implied. This means that you or the Company may terminate the employment relationship at any time with or without cause, subject to any payment obligations set forth herein. Notwithstanding anything contained herein, this “at will” relationship between you and the Company supersedes any and all prior or contemporaneous oral or written promises or agreements and may only be altered by a written document signed by Blackstone.

The payments and benefits under this offer letter agreement are intended to be exempt from Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”), or, if not exempt, in compliance therewith, and, accordingly, to the maximum extent permitted, shall be interpreted to be exempt from Section 409A or in compliance therewith. To the extent any expense or reimbursement described in this offer would constitute “nonqualified deferred compensation” subject to Section 409A, reimbursement shall be made in accordance with Company policy and (i) the amount eligible for reimbursement in one calendar year will not affect the amount eligible for reimbursement in any other calendar year, (ii) reimbursements shall be made on or before the last day of the calendar year following the calendar year in which the applicable expense is incurred, and (iii) the right to payment or in-kind benefits may not be

liquidated or exchanged for any other benefit.

The parties hereto acknowledge and agree that the provisions of this offer letter agreement are fair and reasonable, and that your agreement to the terms hereof, including without limitation, the Restrictive Covenants, is a material inducement for the Company’s executing this offer letter agreement, and in the absence of such agreements by you, the Company would not have executed this offer letter agreement. You further represent and warrant to the Company that you (a) have read this offer letter agreement in its entirety, (b) fully understand the terms of this offer letter agreement, (c) have had the opportunity to consult with counsel prior to executing this offer letter agreement and (d) are signing this offer letter agreement voluntarily and with full knowledge of its significance.

Remedies/Arbitration

Any right to obtain an injunction, restraining order, or other equitable relief hereunder shall not be deemed a waiver of any right to assert any other remedy the Company may have at law or in equity. The right of the Company to seek equitable relief under this paragraph shall be in addition to the requirement imposed on each party hereto to arbitrate disputes as provided below in this section.

Arbitration.

Except as precluded by applicable law or where a breach of a Restrictive Covenant creates the need for injunctive relief as described above, you and the Company agree that any claim, controversy, or dispute

Appendix A –2

between you and the Company (including without limitation its affiliates, officers, employees, representatives, or agents) arising out of or relating to this offer letter agreement, your employment, the cessation of your employment, or any matter relating to the foregoing shall be submitted to and settled by arbitration. This arbitration provision also applies to any labor or employment claims under applicable federal, state, or local statutes, ordinances, regulations, executive orders, common law, or other legal authorities arising out of or relating to your employment with or the termination of your employment with the Company (except for those claims exempted from compulsory arbitration under Section 402 of the Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act, 9. U.S.C. § 402 or any other applicable statutory limit on arbitration). This arbitration provision constitutes a waiver of any right to a jury trial, and you expressly waive your right to participate in any class action or collective action proceedings in any court or arbitration with respect to any legal or contractual disputes with the Company. All disputes between you and the Company must be resolved on an individual basis in accordance with this arbitration provision; provided, however, that nothing in this provision precludes your right to file a charge with any governmental agency (including, without limitation, the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the U.S. Department of Justice or the Securities and Exchange Commission) or to cooperate with any investigation by any governmental agency. This agreement to arbitrate claims shall be governed by and interpreted in accordance with the Federal Arbitration Act (“FAA”). If for any reason the FAA is held inapplicable to this offer letter agreement, then the State of Colorado’s law of arbitrability shall apply.

Any claim, controversy, or dispute described herein shall be submitted to and settled by arbitration in the forum of JAMS, in the location closest to your most recent office at the Company, before a single arbitrator mutually agreed to by the parties, or in the absence of such mutual agreement, selected by JAMS in accordance with JAMS Employment Arbitration Rules and Procedures and conducted in accordance with JAMS Employment Arbitration Rules and Procedures, except as follows: (A) the arbitrator shall agree to treat as confidential evidence and other information presented by the parties to the same extent as Confidential Information (as defined in Appendix B) under this offer letter agreement must be held confidential by you; (B) the arbitrator shall have no authority to amend or modify any of the terms of this offer letter agreement; and (C) the arbitrator shall have 10 business days from the closing statements or submission of post-hearing briefs by the parties to render a reasoned decision. Any arbitration award (regardless of the forum) shall be final and binding upon the parties, and any court, state or federal, having jurisdiction may enter a judgment on the award.

This offer letter agreement shall be construed and enforced in accordance with the internal, substantive laws of the State of Colorado, without giving effect to the conflicts of law principles thereof.

(b) The provisions of Section 2 hereof shall survive the termination of Executive’s employment for any reason.

(ii) “Confidential Information” shall not include any information that is (A) generally known to the industry or the public other than as a result of Executive’s breach of this covenant or any breach of other confidentiality obligations by third parties; (B) made legitimately available to Executive by a third party without breach of any confidentiality obligation of which Executive has knowledge; (C) independently developed by or for Executive without using Confidential Information; (D) about a subject matter on which applicable law prohibits disclosure restrictions; or (E) required by law to be disclosed; provided that with respect to subsection (E) Executive shall give prompt written notice to the Company of such requirement, disclose no more information than is so required, and cooperate with any attempts by the Company to obtain a protective order or similar treatment.

(iv) Nothing in this Agreement shall prohibit or impede Executive from communicating, cooperating or filing a complaint with any U.S. federal, state or local governmental or law enforcement branch, agency or entity (collectively, a “Governmental Entity”) with respect to possible violations of any U.S. federal, state or local law or regulation, or otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or regulation, provided that in each case such communications and disclosures are consistent with applicable law.

Executive understands and acknowledges further that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Notwithstanding the foregoing, under no circumstance will Executive be authorized to disclose any information covered by attorney-client privilege or attorney work product of any member of the Restricted Group without prior written consent of the Company’s General Counsel or other officer designated by the Company.

If the Company is unable for any other reason, to secure Executive’s signature on any document for this purpose, then Executive hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Executive’s agent and attorney in fact, to act for and in Executive’s behalf and stead to execute any documents and to do all other lawfully permitted acts required in connection with the foregoing.

(iii) Executive shall not improperly use for the benefit of, bring to any premises of, divulge, disclose, communicate, reveal, transfer or provide access to, or share with the Company any confidential, proprietary or non-public information or intellectual property relating to a former employer or other third party without the prior written permission of such third party. Executive hereby indemnifies, holds harmless and agrees to defend the Company and its officers, directors, partners, employees, agents and representatives from any breach of the foregoing covenant.
