NOW, THEREFORE, in consideration of the rights and obligations contained herein, and for other good and valuable consideration, the adequacy of which is hereby acknowledged, the parties agree as follows:

Section 1. Amendments the Agreement.

“SECTION 2.03 Contingency Consideration.

(a) Following the Closing, in addition to the consideration to be received pursuant to Section 1.01(c) and 2.02 and as part of the overall Aggregate Consideration, the Blocker Holder and the Company Unitholders shall be issued Fifteen Million (15,000,000) ParentCo Common Shares, in the aggregate (the “Contingency Consideration”), if, at any time prior to or as of the second anniversary of the Closing, the VWAP is greater than or equal to Thirteen Dollars ($13.00) over any twenty (20) trading days within any thirty (30) trading day period (the “Share Target”).

(b) If the Share Target set forth in Section 2.03(a) shall have been achieved, within five (5) Business Days following the achievement of the Share Target, ParentCo shall issue the Contingency Consideration to the Blocker Holder and each Company Unitholder as specified on the Payment Spreadsheet.

(c) If a Change of Control of the ParentCo occurs prior to the second anniversary of the Closing and the Contingency Consideration that is issuable pursuant to Section 2.03(a) remains unissued as of immediately prior to the consummation of such Change of Control, the Contingency Consideration shall immediately vest and the Company Unitholders and the Blocker Holder shall be entitled to receive the Contingency Consideration prior to the consummation of such Change of Control (payable to the Company Unitholders and the Blocker Holder as specified on the Payment Spreadsheet). For the purposes of this Agreement, a “Change of Control” shall have been deemed to occur with respect to ParentCo upon:

(i) the sale, lease, license, distribution, dividend or transfer, in a single transaction or a series of related transactions, of fifty percent (50%) or more of the assets of ParentCo, as applicable, and its subsidiaries taken as a whole;

(ii) a merger, consolidation or other business combination of ParentCo (or any subsidiary or subsidiaries that alone or together represent more than fifty percent (50%) of the consolidated business of ParentCo at that time) or any successor or other entity holding fifty percent (50%) or more all of the assets of ParentCo and its subsidiaries that results in the stockholders of ParentCo (or such subsidiary or subsidiaries) or any successor or other entity holding fifty percent (50%) or more of the assets of ParentCo and its subsidiaries or the surviving entity thereof, as applicable, immediately before the consummation of such transaction or series of related transactions holding, directly or indirectly, less than fifty percent (50%) of the voting power of ParentCo (or such subsidiary or subsidiaries) or any successor, other entity or surviving entity thereof, as applicable, immediately following the consummation of such transaction or series of related transactions; or

(iii) any person or “group” (within the meaning of Rules 13d-3 and 13d-5 under the Exchange Act as in effect on the Closing Date) shall obtain beneficial ownership (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of the voting stock of ParentCo representing more than fifty percent (50%) of the voting power of the capital stock of ParentCo entitled to vote for the election of directors of ParentCo.

(d) The Contingency Consideration and the Share Target shall be adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into ParentCo Common Shares), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to ParentCo Common Shares, occurring on or after the date hereof and prior to the time the Contingency Consideration is delivered to the Blocker Holder and Company Unitholders, if any.”

“(h) Warrantholder Approval. The registered holders of the public NAC Warrants holding at least a majority of the public NAC Warrants shall have approved an amendment to the NAC Warrant Instrument adding a provision pursuant to which there will be an automatic redemption of all public NAC Warrants for $1.50 per whole public NAC Warrant upon the consummation of the Transactions.”

2

Section 2. Waiver of Tender Offer. Section 7.07 of the Agreement provides that, in connection with the Transactions, NAC shall commence the Tender Offer with respect to the publicly held NAC Warrants, including filing with the SEC the Schedule TO, Schedule 14D-9 and other Offer Documents. Notwithstanding the foregoing, the parties to the Agreement have decided that, rather than commencing the Tender Offer, NAC shall instead seek to amend the NAC Warrant Instrument pursuant to the proposed amendment to the NAC Warrant Instrument attached hereto as Exhibit A (the “Warrant Amendment”). To that end, the parties have agreed that, rather than commencing the Tender Offer and filing the Offer Documents, NAC shall call a special meeting of the holders of public NAC Warrants (and include in the notice of such meeting in the Proxy Statement/Prospectus) pursuant to which NAC shall seek the consent of the holders of the public NAC Warrants to the Warrant Amendment. The parties hereby waive NAC’s obligation to perform NAC’s obligations under Sections 2.05 and Section 7.07 of the Agreement.

Section 3. Parties in Interest. This Amendment shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Amendment, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Amendment.

Section 4. Entire Agreement. This Amendment constitutes the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof. Except as amended by this Amendment, the Agreement shall continue in full force and effect.

Section 5. Counterparts. This Amendment may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

Section 6. Governing Law. This Amendment shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed in that State.
