by counsel of its own choosing at its sole cost and expense. 

  

	 	(b)	The indemnifying party shall have full authority to determine all action to be taken with respect thereto; provided, however, that the indemnifying party will not have the authority to subject the
indemnified party to any obligation whatsoever, other than the performance of purely ministerial tasks or obligations not involving material expense or injunctive relief. If the indemnifying party does not elect to contest any such Third Party
Indemnity Claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party assumes the defense of a Third Party Indemnity Claim, the indemnified party shall agree to any
settlement, compromise or discharge of a Third Party Indemnity Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Third Party
Indemnity Claim, which releases the indemnified party completely in connection with such Third Party Indemnity Claim and which would not otherwise adversely affect the indemnified party as determined by the indemnified party in its sole discretion.

  

	 	(c)	Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Third Party Indemnity Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the
indemnified party in defending such Third Party Indemnity Claim) if the Third Party Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party which the indemnified party
reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Third Party Indemnity Claim can be so separated from that for
money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages. 

  
 22 

 Section 5.6    Cooperation. 

If requested by the indemnifying party, the indemnified party agrees to cooperate with the indemnifying party and its counsel in contesting any
Third Party Indemnity Claim that the indemnifying party elects to contest or, if appropriate, in making any counterclaim against the person asserting the Third Party Indemnity Claim, or any cross-complaint against any person, and the indemnifying
party will reimburse the indemnified party for any expenses incurred by it in so cooperating. At no cost or expense to the indemnified party, the indemnifying party shall cooperate with the indemnified party and its counsel in contesting any Third
Party Indemnity Claim. 
 Section 5.7    Right to Participate. 

The indemnified party agrees to afford the indemnifying party and its counsel the opportunity to be present at, and to participate in,
conferences with all Persons, including Governmental Authorities, asserting any Third Party Indemnity Claim against the indemnified party or conferences with representatives of or counsel for such Persons. 

Section 5.8    Payment of Damages. 

The indemnification required hereunder shall be made by periodic payments of the amount of Damages in connection therewith within ten
(10) days as and when reasonably specific bills are received by, or Damages are incurred and reasonable evidence thereof is delivered to, the indemnifying party. In calculating any amount to be paid by an indemnifying party by reason of the
provisions of this Agreement, the amount shall be reduced by all insurance proceeds and any indemnification reimbursement proceeds received from third parties credited to or received by the indemnified party related to the Damages. 

Section 5.9    Direct Claim. 

Any claim by an indemnified party with respect to any Damages which do not result from a Third Party Indemnity Claim (a “Direct
Claim”) will be asserted by giving the indemnifying party reasonably prompt written notice thereof, stating the nature of such claim in reasonable detail and indicating the estimated amount, if practicable. The indemnifying party will have
a period of ninety (90) days from receipt of such Direct Claim within which to respond to such Direct Claim. If the indemnifying party does not respond within such ninety (90) day period, the indemnifying party will be deemed to have
accepted such Direct Claim. If the indemnifying party rejects such Direct Claim, the indemnified party will be free to seek enforcement of its rights to indemnification under this Agreement. 

Section 5.10    Limitations on Indemnification. 

 

	 	(a)	 To the extent that the Partnership Indemnified Parties would otherwise be entitled to indemnification for Damages
pursuant to Section 5.1(i), Development and Tallgrass Holdco shall be liable only if (i) the Damages with respect to any individual claim exceed $80,000 (the “Minimum Claim Amount”) and (ii) the
Damages for all claims that exceed the Minimum Claim Amount exceed, in the aggregate, $4,000,000 (the “Deductible 

  
 23 

	 	
Amount”), and then Development and Tallgrass Holdco shall be liable only for Damages to the extent of any excess over the Deductible Amount. In no event shall Development’s and
Tallgrass Holdco’s aggregate liability to the Partnership Indemnified Parties under Section 5.1 exceed $40,000,000 (the “Ceiling Amount”). Notwithstanding the foregoing, the Deductible Amount and the
Ceiling Amount shall not apply to breaches or inaccuracies of representations and warranties contained in Section 3.1, Section 3.2, Section 3.4 and
Section 3.16. 

  

	 	(b)	Additionally, neither the Partnership, on the one hand, nor Development and Tallgrass Holdco, on the other hand, will be liable as an indemnitor under this Agreement for any consequential, incidental, special, indirect
or exemplary damages suffered or incurred by the indemnified party or parties except to the extent resulting pursuant to Third Party Indemnity Claims. 

  

	 	(c)	Notwithstanding anything to the contrary in this Agreement, in the event that Damages suffered by a Partnership Indemnified Party are recoverable under this Agreement and that certain Purchase and Sale Agreement, dated
as of January 1, 2017, by and between Development and the Partnership (the “NatGas/Terminals Purchase Agreement”), such Partnership Indemnified Party will only be permitted to recover with respect to any particular
Damages suffered by it one time, as it is the intent of Development, Tallgrass Holdco and the Partnership that once any particular Damages have been recovered by a particular Partnership Indemnified Party under this Agreement or the NatGas/Terminals
Purchase Agreement, as applicable, such Damages no longer exist with respect to such Partnership Indemnified Party and, therefore, recovery by such Partnership Indemnified Party for such Damages under the other of this Agreement or the
NatGas/Terminals Purchase Agreement, as applicable, would constitute an unintended and prohibited “double” recovery. 

Section 5.11    Sole Remedy. 

No party shall have liability under this Agreement, the Assignment Agreement or the transactions contemplated hereby or thereby except as is
provided in this Article V (other than claims or causes of action arising from fraud). 
 ARTICLE VI

state courts in Johnson County, Kansas and in the federal courts of Wyandotte County, Kansas.

	 	(c)	Each party to this Agreement waives, to the fullest extent permitted by Applicable Law, any right it may have to receive damages from any other party based on any theory of liability for any special, indirect,
consequential (including lost profits), exemplary or punitive damages (except to the extent that any such damages are included in indemnifiable losses resulting from a third party claim in accordance with Article V).

Amendments and Waivers. 
  

	 	(a)	 This Agreement and the Assignment Agreement constitute the entire agreement among the parties with respect to the
subject matter hereof and supersede all prior agreements and understandings, both written and oral, 

  
 27 

	 	
among the parties with respect to the subject matter hereof. Each party to this Agreement agrees that no other party to this Agreement (including its agents and representatives) has made any
representation, warranty, covenant or agreement to or with such party relating to this Agreement or the transactions contemplated hereby, other than those expressly set forth herein and in the Assignment Agreement. 

 

	 	(b)	No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by each party to be bound thereby. No waiver of any of the provisions of this Agreement shall be deemed or shall
constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided. 

Section 6.8    Conflicting Provisions.

This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns, but
neither this Agreement nor any of the rights, benefits or obligations hereunder shall be assigned or transferred, by operation of law or otherwise, by any party hereto without the prior written consent of each other party. Nothing in this Agreement,
express or implied, is intended to confer upon any person or entity other than the parties hereto and their respective permitted successors and assigns, any rights, benefits or obligations hereunder, except for express language with respect to the
Partnership Indemnified Parties and the Development Indemnified Parties contained in the indemnification provisions of Article V.

provisions of this Agreement shall remain in full force and effect. 
 Section 6.11    Interpretation. 

It is expressly agreed by the parties that neither this Agreement nor the Assignment Agreement shall be construed against any party, and no
consideration shall be given or presumption made, on the basis of who drafted this Agreement, the Assignment Agreement or any provision hereof or thereof or who supplied the form of this Agreement or the Assignment

  
 28 

 
Agreement. Each party agrees that this Agreement has been purposefully drawn and correctly reflects its understanding of the transactions contemplated by this Agreement and, therefore, waives the
application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

 Exhibit A 

Form of Assignment Agreement 

See Attached. 

 ASSIGNMENT AGREEMENT 

This ASSIGNMENT AGREEMENT (this “Assignment”), dated as of March 31, 2017, is entered into by and among Rockies Express
Holdings, LLC, a Delaware limited liability company (“Assignor”), Tallgrass Energy Partners, LP, a Delaware limited partnership (the “Partnership”), and TEP REX Holdings, LLC, a Delaware limited liability company
(“Assignee”). Assignor, the Partnership and Assignee may be referred to individually as a “Party” or collectively as the “Parties.” 

RECITALS 

A.    Pursuant to the terms of a Purchase and Sale Agreement (the “Purchase Agreement”, with capitalized
terms used but not defined herein having the respective meanings set forth in the Purchase Agreement), dated as of the date hereof, among Assignor, the Partnership, and Tallgrass Development, LP, a Delaware limited partnership, Assignor will
transfer to Assignee (an indirect wholly-owned subsidiary of the Partnership) a 24.99% membership interest in Rockies Express Pipeline LLC, a Delaware limited liability company (the “Company”) (such 24.99% membership interest in the
Company, the “Subject Interest”). 
 NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Parties agree as follows: 
 AGREEMENT 

1.1.    Assignment of the Subject Interest. Assignor hereby grants, bargains, conveys, assigns, transfers, sets
over and delivers the Subject Interest to Assignee, and Assignee hereby accepts the Subject Interest.

2017 RLHC Executive Officers Bonus Plan

Purpose
RLHC is committed to compensating employees through comprehensive and competitive pay packages that include base salary, bonus programs, incentive plans, competitive benefits plans, and reward and recognition programs. These programs are designed to motivate employees to exceed performance expectations in support of the company’s business objectives.
The Executive Officers Bonus Plan (“Plan”) provides the opportunity for annual bonus payments to the contributors who drive the successful attainment of company goals. The success of the company relies on many factors. Adjusted EBITDA is the main driver behind this plan, however; our success also depends on department and individual goals. 

Plan Year
January 1, 2017 to December 31, 2017

Eligible Employees; Target Bonus and Maximum Bonus

	
			
	Eligible Employees
	Target Bonus

	Chief Financial Officer
	70% of Base Salary
	112% of Base Salary

	Chief Executive Officer
	100% of Base Salary
	160% of Base Salary

An employee must hold one of the above positions at the beginning of the Plan Year to be eligible to participate in this Plan. Transfers to an ineligible position that occurs after the Plan Year will not affect any bonus earned during the Plan Year.  Position transfers that occur during the Plan year may result in a pro-rated bonus amount for each position based upon the target bonus amount and the achievement of bonus criteria for each position. 

Plan Components
Whether a participant will receive a bonus under the Plan depends on the extent to which the following goals are achieved:

(1)    A company goal based on target Adjusted EBITDA for 2017 (“Target Adjusted EBITDA”);
		
	(2)
	One or more department goals based on applicable division or department performance such as gross operating profit; revenues from group business; RevPar growth; increase in RevPar index; improvement in customer service competitive quality index; associate engagement; and addition of franchised and managed hotels to RLHC’s system of hotels; and

		
	(3)
	One or more individual goals such as execution of growth initiatives or other corporate strategic goals and/or personal development. 

The department and individual goals are established by the CEO and Compensation Committee.

Bonus Calculation
For purposes of calculating the bonuses, if any, due under this Plan, the company goal achievement (“EBITDA Goal Achievement”) will be the fraction (expressed as a percentage) determined by dividing (i) RLHC’s 2017 Adjusted EBITDA, as disclosed in the 2017 Form 10‐K, by (ii) Targeted Adjusted EBITDA. There will be no bonus payout to the participants under this calculation unless this percentage exceeds 87.8%.

The EBITDA Goal Achievement percentage will determine the tentative payouts, if any, to which the participants are entitled, as set forth in or determined from the following applicable table:

(1)  The Target Multiplier and tentative payout percentages will be linearly interpolated for EBITDA Goal Achievement percentages that are between any two percentages shown in the table.

If a participant achieves both his department and individual goals, he will be entitled to a payout (“Full Payout”) equal to the percentage of base salary determined from the above table for the RLHC EBITDA Goal Achievement percentage. If the participant achieves less than all of his department and individual goals, he will be entitled to between 80% and 99% of the Full Payout. If the participant achieves neither his department nor his individual goals, then he will be entitled to 80% of the Full Payout.

Clawback
A participant who receives a bonus under the Plan will be required to repay the bonus to RLHC to the extent required by (i) any “clawback” or recoupment policy adopted by RLHC to comply with the requirements of any applicable laws, rules or regulations, or (ii) any applicable law, rule or regulation that imposes mandatory recoupment.

Administration
The Director of Compensation and Benefits, EVP HR, and CFO will administer the Plan.

Calculation, Approval and Payment
As soon as the necessary information is available following the end of the Plan Year, the EVP HR and the VP, Accounting will complete the bonus calculations for each participant and submit them to the CFO for review and approval. Once approved by the CFO, he will submit the bonus calculations to the Compensation Committee for final approval. Upon Compensation Committee approval, the CFO will provide the payment information to the VP, Accounting and EVP, HR for recordkeeping, who will in turn submit it to the payroll office for payments. Payments will be made to participants as soon as administratively possible following the end of the bonus period. Typically, payments are approved following the February Board meeting and paid as soon as practical thereafter. Calculations are based on the base salary of the participant on the last day of the Plan Year.

Effect of Change in Employment Status/Termination
Leaves of Absences:  To the extent a participant qualifies for an approved leave of absence, that participant’s bonus will not be forfeited, but rather will be prorated. If the leave involves accrued paid leave, the bonus will be unaffected. If the leave involves unpaid leave, the bonus will be prorated based upon the actual number of days worked plus any paid leave as a proportion of the full Plan Year. 

Terminations:  Bonuses for this Plan are not earned or vested until they are approved by the Compensation Committee and paid. Any bonuses earned will be determined and paid on or before March 31, 2018. To encourage continued employment with RLHC, participants must be employed as of the date of payout in order to earn a bonus. Therefore, any participant whose employment terminates prior to the date of payout will not earn, vest in, or receive a bonus.

General Provisions
There is an overriding discretionary analysis of each participant’s eligibility to receive a bonus. Even though an individual might earn a bonus based on the terms of this Plan, a bonus can be adjusted up or down or not paid entirely in the sole discretion of the Compensation Committee Directors. For example a bonus may be adjusted down for overall substandard work performance of the participant, including, but not limited to the below. For example, if a participant fails to follow company policy and procedures, exposes the company to legal liability, exhibits inappropriate behavior, withholds information, or does not adequately follow through on critical incidents, he or she may be disqualified from receiving a bonus. Other disqualifiers may include unacceptable performance against established performance objectives, unacceptable scores on internal audit processes (e.g., HR, Accounting, Risk Management, Internal Audit, Quality Assurance), or poor associate or customer satisfaction scores.

Notwithstanding anything to the contrary in this Plan, individual bonus payments may be deferred, partially paid or withheld in their entirety, at the sole discretion of the Compensation Committee, in consideration of the overall best interests of the company. RLHC reserves the right to cancel, change, modify or interpret any and all provisions of the Plan at any time without notice. Participation in the Plan does not create any entitlement to continued employment and does not alter the at-will status of participants. This Plan will be governed and construed in accordance with the laws of the state of Washington.

This Plan supersedes all previous plans in existence and any past written or verbal communication to any participant regarding the terms of any incentive plan.
