“Section 8.9. Additional Interest. With respect to all Notes:

(a)    upon the occurrence of a Trigger Event, (i) (A) solely with respect to a Test One Failure, the interest rate with respect to the Notes shall be immediately and automatically increased by 0.50% per annum for the remaining life of the Notes (subject to the provisions of Section 8.9(b)), and (B) with respect to a Test Two Failure, the interest rate with respect to the Notes shall be immediately and automatically increased by an additional 0.50% per annum (which such increase will be in addition to the then existing increase specified in clause (A) of this Section 8.9(a)(i) for an aggregate increase in the interest rate with respect to the Notes of 1.00% per annum) for the remaining life of the Notes (subject to the provisions of Section 8.9(b)) and (ii) the Company shall, on the next date on which interest payments are due to be made under the terms of the Notes (each such date, an “Interest Payment Date”) following any such Trigger Event, pay to each holder of such Notes a one-time payment for such Trigger Event in an amount equal to the product of (x)(I) if such Trigger Event resulted solely as a result of a Test One Failure, 0.50%, (II) if such

1

Trigger Event resulted solely as a result of a Test Two Failure, 0.50% (i.e., a Test One Failure had occurred in a prior period and no Reset Event had occurred for such Test One Failure) and (III) if such Trigger Event exists as a result of both a Test One Failure and a Test Two Failure, 1.00%, (y) the aggregate principal amount of Notes held by such holder or its predecessor holder as of the end of the most recently completed fiscal quarter of the Company for which the Company is required to deliver financial statements pursuant to Sections 7.1 (a) or (b), as the case may be, and giving effect to any reduction in principal of the Notes since the end of such fiscal quarter, and (z) a fraction, the numerator of which is the number of days from and including the end of the most recently completed fiscal quarter described in the immediately preceding clause (y) to, but excluding the date of, the occurrence of the Trigger Event and the denominator of which is 360;

(b)    if, at any time following (I) a Trigger Event where a Test Two Failure existed, no Test Two Failure shall continue to exist or (II) a Trigger Event where a Test One Failure existed, no Test One Failure shall continue to exist (each a “Reset Event”; provided, however, that such Reset Event shall be deemed to occur on the date upon which the Company delivers its quarterly or annual financial statements and accompanying certificates pursuant to Sections 7.1 and 7.2 demonstrating satisfaction of the aforementioned conditions), (i) the interest rate with respect to the Notes shall be immediately and automatically reduced by 0.50% (or, with respect to a Reset Event occurring as a result of the satisfaction of both clauses (I) and (II) above, 1.00%) per annum for the remaining life of the Notes (subject to the provisions of Sections 8.9(a) and (c)) and (ii) each holder of Notes shall apply a one-time credit, on the next Interest Payment Date of the Notes following such Reset Event, to the accrued interest owed by the Company with respect to the Notes by an amount equal to the product of (x)(A) if only one of the above clauses (I) and (II) caused the Reset Event, 0.50% or (B) if both of the above clauses (I) and (II) caused the Reset Event, 1.00%, (y) the aggregate principal amount of Notes held by such holder or its predecessor holder as of the end of the most recently completed fiscal quarter of the Company for which the Company is required to deliver financial statements pursuant to Section 7.1 (a) or (b), as the case may be, and giving effect to any reduction in principal of the Notes since the end of such fiscal quarter, and (z) a fraction, the numerator of which is the number of days from and including the end of the most recently completed fiscal quarter described in the immediately preceding clause (y) to, but excluding the date of, the occurrence of the Reset Event and the denominator of which is 360;

(c)    notwithstanding anything in this Section 8.9 to the contrary, another Trigger Event may follow a Reset Event, in which case the provisions of Sections 8.9(a) and (b) shall apply; and

(d)    for the avoidance of doubt and notwithstanding anything in this Section 8.9 or otherwise in this Agreement to the contrary, upon the occurrence and during the continuance of an Event of Default, the interest rate with respect to the Notes shall be at the default rate as set forth in clause (b) of the first paragraph of each Note, and such rate shall be automatically increased by the applicable rate specified in Section 8.9(a) for all periods during which a Trigger Event continues to exist.”

(c)    Amendment to clause (a) of Section 10.6 (Financial Covenants) of the Existing Note Purchase Agreement. Clause (a) of Section 10.6 (Financial Covenants) of the Existing Note Purchase Agreement is hereby amended and restated in its entirety as follows:

“(a)    Commencing with the fiscal quarter ended June 30, 2016, the Company will not permit the Leverage Ratio of the Note Parties to be greater than 4.75 to 1.00 as of the last day of any fiscal quarter. Commencing with the fiscal quarter ending December 31, 2018, the Company will not permit the Leverage Ratio of the Note Parties to be greater than 4.25 to 1.00 as of the last day of any fiscal quarter.”

For purposes of this Section 10.21, any such amendment or modification that (1)(x) introduces a separate maximum secured leverage ratio in addition to a maximum total leverage ratio or (y) modifies the working capital loan exception in the numerator of such leverage ratio shall be deemed “significant” and (2)

2

increases or decreases the maximum total leverage ratio shall not be deemed “significant.” Regardless of whether any such amendment or modification is “significant” for purposes of this Section 10.21, the holders expressly reserve their rights under Section 10.20 with respect to any amendment or modification of the Credit Agreement.”

(e)    Amendments to Schedule B to the Existing Note Purchase Agreement. Schedule B to the Existing Note Purchase Agreement is hereby amended as follows:

(i) The definition of “Consolidated EBITDA” is hereby amended and by amending and restating in its entirety clause (B) in the final proviso of such definition, as follows:

“(B) with regard to each Major Permitted Business Expansion Project, excluding the Grand Mesa Project, such pro forma adjustment (x) shall be based upon forecasted income to be derived from binding, non-contingent contracts less appropriate direct and indirect costs to realize such income and (y) when aggregated with all pro forma adjustments attributable to Major Permitted Business Expansion Projects, excluding the Grand Mesa Project, shall not exceed 15.00% of the Consolidated EBITDA reflected in the most recently delivered Compliance Certificate, net of any actual Consolidated EBITDA realized from such Major Permitted Business Expansion Projects (excluding the Grand Mesa Project) and without giving effect to increases in such Consolidated EBITDA arising from such Major Permitted Business Expansion Projects for such pro forma period; provided that with respect to the Grand Mesa Project, Consolidated EBITDA shall be based on (i) forecasted income to be derived from binding, non-contingent contracts less appropriate direct and indirect costs to realize such income and (ii) income from FERC required walk-up volume capped at 10,000 bpd (subject to the limitation that the sum of the immediately preceding clauses (i) and (ii) shall not exceed $140,000,000 for any four quarters ending on or prior to the date of determination) multiplied by the applicable GMP Completion Percentage as of the end of such period; provided, further, that to the extent the Grand Mesa Project is not complete as of December 31, 2016, the contribution of the Grand Mesa Project to Consolidated EBITDA will be reduced by 25% per quarter for each quarter commencing with the fiscal quarter ending December 31, 2016.”

(ii) The definition of “GMP Completion Percentage” is hereby amended and restated in its entirety as follows:

“GMP Completion Percentage” with respect to the determination of Consolidated EBITDA for any period, the percentage of completion for the Grand Mesa Project determined as the quotient (expressed as a percentage) of the costs incurred by the Note Parties as of the end of the applicable period over the estimated total project cost of the Grand Mesa Project at such time. As of the Amendment No. 11 Effective Date, the Note Parties have incurred costs in connection with the Grand Mesa Project in an amount equal to $770,000,000 and the estimated total project cost as of such date is $831,000,000.

(iii) The definition of “Test Two Failure” is hereby added to Schedule B of the Existing Note Purchase Agreement in appropriate alphabetical order to read in its entirety as follows:

“Test Two Failure” shall mean, at any time, the existence of a Leverage Ratio (measured quarterly as of the end of each fiscal quarter) which is greater than 4.50 to 1.00.”

(iv) The definition of “Trigger Event” in Schedule B of the Existing Note Purchase Agreement is hereby amended by inserting the text “or Test Two Failure” after each reference to “Test One Failure” contained in such definition.

Section 2. LIMITED CONSENT. Subject to the satisfaction of the conditions set forth in Section 3 below, the Noteholders hereby consent to (i) the Collateral Agent’s release of its Lien on any Collateral in accordance with Section 8.17 of the Security Agreement and any other applicable provision of any Security Document, providedthat (a) the sale, lease, transfer or other disposition of such Collateral is permitted pursuant to the terms of the Note Purchase Agreement, (b) the Company provides the Noteholders prior written notice of such release, which notice (I) shall specify the Section or Sections of the Note Purchase Agreement permitting the Company to sell, lease, transfer or otherwise dispose of such Collateral and (II) may be included in any officer’s certificate referenced in the following clause (c), and (c) the Company shall provide the Noteholders a copy of any officer’s certificate delivered to the Collateral Agent in connection with such release (including, without limitation, any officer’s certificate delivered pursuant to Section 8.17(a)(ii) of the Security Agreement); provided that delivery by the Company of any such notice and certificate to the outside counsel for the Noteholders shall constitute delivery to the Noteholders for the purposes of this limited

3

consent, and (ii) the Collateral Agent’s execution and delivery of any Security Document, or any amendment or supplement to any Security Document, solely for purposes of (x) granting or perfecting a security interest in or lien on assets or property of any Note Party in favor of the Collateral Agent, for the benefit of the Noteholders and the other Secured Parties, or (y) releasing a Lien permitted to be released pursuant to clause (i) above, provided that in the case of each of clause (x) and (y), outside counsel for the Noteholders are provided a draft of any such Security Document, amendment or supplement and are afforded a reasonable opportunity to review and comment upon the same before its execution. The foregoing consent shall serve as the written notice and direction from the Required Holders to the Collateral Agent (I) pursuant to Section 8.17 of the Security Agreement and Section 21 of the Intercreditor Agreement in connection with any such release of Collateral and (II) pursuant to Section 23 of the Intercreditor Agreement in connection with the execution and delivery of any such future Security Documents, amendments or supplements; provided that the Administrative Agent, Technical Agent and/or requisite number of Lenders, as applicable, has or have also provided their written notice and direction, or such written notice and direction has been given automatically under the Loan Documents (as defined in the Credit Agreement), in connection with any such release or execution and delivery. Subject to the foregoing, nothing contained in this Amendment shall be construed as a waiver by the Noteholders of any covenant or provision of the Note Purchase Agreement or the other Note Documents, and the failure of the Noteholders at any time or times hereafter to require strict performance of any provision thereof shall not waive, affect or diminish any right of the Noteholders to thereafter demand strict compliance therewith. The Noteholders hereby reserve all rights granted under the Note Purchase Agreement and the other Note Documents. The parties hereby agree that the Collateral Agent is an express third party beneficiary of this limited consent and, as such, shall be permitted to rely on such limited consent with respect to the release of its Lien on any Collateral in accordance with Section 8.17 of the Security Agreement and any other applicable provision of any Security Document and the Collateral Agent’s execution and delivery of any Security Document, or any amendment or supplement to any Security Document.
