A.    The Borrower, the Administrative Agent, the Issuing Lenders and the Lenders are parties to that certain Credit Agreement dated as of September 14, 2017 (as amended, modified, supplemented, restated or amended and restated prior to the date hereof, the “Credit Agreement”), pursuant to which the Lenders have agreed to make certain loans to, and extensions of credit on behalf of, the Borrower on and after the Funding Date, subject to the terms and conditions of the Credit Agreement.

B.    The Borrower, the Administrative Agent, the Issuing Lenders and the Lenders have agreed, subject to the terms and conditions herein, to amend certain provisions of the Credit Agreement to, among other things, (i) extend the date by which the Funding Date must occur from not later than December 13, 2017 to not later than February 12, 2018 and (ii) amend certain conditions precedent to the Funding Date.

C.    NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Section 1.    Defined Terms. Each capitalized term used herein but not otherwise defined herein has the meaning given to such term in the Credit Agreement.

Section 2.    Amendments to Credit Agreement.

2.1    Amendments to Section 1.1.

(a)    The following terms contained in Section 1.1 of the Credit Agreement are hereby amended and restated in their entirety with the following text:

““Adjusted Base Rate” means, for any day, a rate per annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Rate in effect on such day plus  ¹⁄₂ of 1.0% and (c) the Adjusted Eurocurrency Rate for an Interest Period of one month on such day (or if such day is not a Business Day, the immediately preceding Business Day) plus 1.0%; provided that for the purpose of this definition, the Adjusted Eurocurrency Rate for any day shall be based on the Eurocurrency Base Rate (or if the Eurocurrency Base Rate is not available for such one month Interest Period, the Interpolated Rate) at approximately 11:00 am (London, England time) on such day. Any change in the Adjusted Base

Rate due to a change in the Prime Rate, the Federal Funds Rate or the Adjusted Eurocurrency Rate shall be effective from and including the effective date of such change in the Prime Rate, the Federal Funds Rate or the Adjusted Eurocurrency Rate, respectively. If the Adjusted Base Rate is being used as an alternate rate of interest pursuant to Section 2.4(c)(v) or Section 2.4(c)(vi) hereof, then the Adjusted Base Rate shall be the greater of clause (a) and clause (b) above and shall be determined without reference to clause (c) above. For the avoidance of doubt, if the Adjusted Base Rate shall be less than zero, such rate shall be deemed to be zero for purposes of this Agreement.

“Federal Funds Rate” means, for any day, the greater of (a) the rate calculated by the Federal Reserve Bank of New York based on such day’s federal funds transactions by depositary institutions (as determined in such manner as the Federal Reserve Bank of New York shall set forth on its public website from time to time) and published on the next succeeding Business Day by the Federal Reserve Bank of New York as the federal funds effective rate and (b) the rate comprised of both overnight federal funds and overnight eurodollar advances by United States managed banking offices of depository institutions, as such composite rate shall be determined by the Federal Reserve Bank of New York as set forth on its public website from time to time, and published on the next succeeding Business Day by the Federal Reserve Bank of New York as an overnight bank funding rate (from and after such date as the Federal Reserve Bank of New York shall commence to publish such composite rate); provided that if neither of such rates are published for any day that is a Business Day, the term “Federal Funds Rate” means the rate for a federal funds transaction quoted at 11:00 a.m. on such day received by the Administrative Agent from a federal funds broker of recognized standing selected by it; provided, further, that if any of the aforesaid rates shall be less than zero, such rate shall be deemed to be zero for purposes of this Agreement.

“Offering” means a public offering and sale of Equity Interests in the Borrower closing on or about the Funding Date with gross proceeds of not less than $125,000,000.”

(b)    Each reference to the term “Alternate Base Rate” in the definitions of “Adjusted Eurocurrency Rate”, “Eurocurrency Base Rate” and “Eurocurrency Rate” is hereby deleted and replaced with the term “Adjusted Base Rate”.

2.2    Amendment to Section 2.4. Section 2.4(c)(v) of the Credit Agreement is hereby amended by inserting the following text immediately after the last sentence thereof:

“If at any time the Administrative Agent determines (which determination shall be conclusive absent manifest error) that (i) the circumstances set forth in this Section 2.4(c)(v) have arisen and such circumstances are unlikely to be

2

temporary or (ii) the circumstances set forth in this Section 2.4(c)(v) have not arisen but the supervisor for the administrator of the Eurocurrency Base Rate or a Governmental Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the Eurocurrency Base Rate shall no longer be used for determining interest rates for loans, then the Administrative Agent and the Borrower shall endeavor to establish an alternate rate of interest to the Eurocurrency Rate that gives due consideration to the then prevailing market convention for determining a rate of interest for syndicated loans in the United States at such time, and shall enter into an amendment to this Agreement to reflect such alternate rate of interest and such other related changes to this Agreement as may be applicable. Notwithstanding anything to the contrary in Section 9.2, such amendment shall become effective without any further action or consent of any other party to this Agreement so long as the Administrative Agent shall not have received, within five Business Days of the date notice of such alternate rate of interest is provided to the Lenders, a written notice from the Majority Lenders stating that such Majority Lenders object to such amendment. Until an alternate rate of interest shall be determined in accordance with this Section 2.4(c)(v) (but, in the case of the circumstances described in clause (ii) of the second sentence of this Section 2.4(c)(v), only to the extent the Eurocurrency Base Rate for such Interest Period is not available or published at such time on a current basis), (x) any Notice of Continuation or Conversion that requests the conversion of any Advance to, or continuation of any Advance as, a Eurocurrency Advance shall be ineffective, and (y) if any requests for the making of any Advance requests a Eurocurrency Advance, such Advance shall be made as a Base Rate Advance; provided that, if such alternate rate of interest shall be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement.”

2.3    Amendment to Section 2.5. Section 2.5(c)(iii)(A)(1) of the Credit Agreement is hereby amended by deleting “$175,000,000” therein and replacing it with “$150,000,000”.

2.4    Amendment to Section 3.2. Section 3.2 of the Credit Agreement is hereby amended by amending and restating clauses (k) and (m) thereof in their entirety with the following text:

“(k) Liquidity. The Administrative Agent shall have received evidence satisfactory to it that, after giving effect to the Transactions, Liquidity is greater than or equal to $60,000,000.”

“(m) Funding Date. The Funding Date shall have occurred on or prior to February 12, 2018.”
