WHEREAS, immediately prior to the Effective Time, each outstanding share appreciation right of the Company (each, a “Company SAR”) granted pursuant to the Company’s 2015 Equity Incentive Plan (as amended, the “Company Plan”) shall be converted into an option to purchase Common Shares (each a “Converted SAR”);

WHEREAS, the board of directors of the Company and the board of directors of the Parent have approved the Restructuring, this Agreement, the Merger, the Contribution and the other transactions contemplated hereby;

WHEREAS, by execution of this Agreement, the Parent, as sole member of Merger Sub and owner of all of the interests in Merger Sub, is hereby approving the Restructuring, this Agreement, the Merger, the Contribution and the other transactions contemplated hereby;

WHEREAS, notwithstanding any provision of the Operating Agreement, by execution of this Agreement, the Members, constituting all of the members of the Company and the owners of all of the Company Shares, are hereby approving the Restructuring, this Agreement, the Merger, the Contribution and the other transactions contemplated hereby;

WHEREAS, the transactions contemplated by the Restructuring and the IPO require no further action by the Members; and

3A. Conversion of Securities of the Company.

(i) At the Effective Time (and, for the avoidance of doubt, following the Contribution), by virtue of the Merger and without any action on the part of the holders of shares of the Company or any member of or holder of limited liability company interests in the Merger Sub:

(a) All limited liability interests of Merger Sub issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted solely into the right to receive shares in the Surviving Company following the Effective Time as is set forth opposite Parent’s name in Annex A (such shares, together with the shares held by the Blockers in the Surviving Company, shall constitute all the outstanding shares of the Surviving Company).

(b) All shares of capital stock of the Company (the “Company Shares”) held by the Company or any wholly owned Subsidiary of the Company (or held in the Company’s treasury) immediately prior to the Effective Time shall be cancelled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(c) Each common share of the Company (“Common Shares”) held by the Members (other than the Blockers) immediately prior to the Effective Time will, by virtue of the Merger and without any action on the part of the holder thereof, be converted solely into the right to receive 5.65 share(s) of Parent Stock. As of the Effective Time, all such Common Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist.

(d) Each Series A Preferred share of the Company (“Series A Preferred Shares”) held by the Members (other than the Blockers) immediately prior to the Effective Time will, by virtue of the Merger and without any action on the part of the holder thereof, be converted solely into the right to receive 5.65 share(s) of Parent Stock. As of the Effective Time, all such Series A Preferred Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist.

(e) Each Series B-1 Preferred share of the Company (“Series B-1 Preferred Shares”) held by the Members (other than the Blockers) immediately prior to the Effective Time will, by virtue of the Merger and without any action on the part of the holder thereof, be converted solely into the right to receive 5.65 share(s) of Parent Stock. As of the Effective Time, all such Series B-1 Preferred Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist.

(f) Each Series B-2 Preferred share of the Company (“Series B-2 Preferred Shares”) held by the Members (other than the Blockers) immediately prior to the Effective Time will, by virtue of the Merger and without any action on the part of the holder thereof, be converted solely into the right to receive 5.65 share(s) of Parent Stock. As of the Effective Time, all such Series B-2 Preferred Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist.

(g) Each Series C Preferred share of the Company (“Series C Preferred Shares”) held by the Members (other than the Blockers) immediately prior to the Effective Time will, by virtue of the Merger and without any action on the part of the holder thereof, be converted solely into the right to receive 5.65 share(s) of Parent Stock. As of the Effective Time, all such Series C Preferred Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist.

(h) Each Company Share held by the Parent or a Blocker immediately prior to the Effective Time will, by virtue of the Merger and without any action on the part of the holder thereof, be converted solely into the right to receive shares in the Surviving Company following the Effective Time as is set forth opposite the Parent’s or such Blocker’s name in Annex A.

(i) From and after the Effective Time, except as set forth in Subsections 3A(i)(a) and 3A(i)(h), the holders of Company Shares immediately prior to the Effective Time shall cease to have any rights with respect to such Company Shares and their sole rights shall be those which they will have as holders of shares of Parent Stock.

3B. Treatment of Company Options, SARs and Company Plans.

(a) Immediately prior to the Effective Time, the Company shall convert each outstanding Company SAR into a Company Option by amending the terms of such Company SAR to, among other things, (i) redefine the term “measurement price” as “exercise price”, (ii) permit payment of the exercise price by one or more of the methods provided in Section 5(e) of the Company Plan and (iii) provide, upon the exercise of the award, for the issuance of a number of shares equal to the number of shares exercised (other than in connection with a “net exercise” pursuant to which the Company will reduce the number of shares issuable upon exercise by the largest whole number of shares with a fair market value that does not exceed the aggregate exercise price) (such amendment, the “SAR Conversion”).

(b) At the Effective Time, each Company Option (including, for the avoidance of doubt, each Converted SAR), that has been issued pursuant to the Company Plan and is outstanding immediately prior to the Effective Time (after giving effect to the SAR Conversion) shall be canceled in exchange for a non-qualified stock option under the 2017 Stock Option and Incentive Plan (each, a “Parent Option” under the “Parent Plan”). Such cancellation and substitution shall be effected in a manner that complies with Sections 409A and 424 of the Code. Each Parent Option shall otherwise continue to have, and be subject to, the same terms and conditions (including the vesting arrangements and other terms and conditions set forth in the Company Plan and the applicable agreement) as in effect immediately prior to the Effective Time (after giving effect to the SAR Conversion), except that (a) such option shall become exercisable for that number of shares of Parent Stock, equal to the product of (i) the number of Common Shares that would have been issuable upon exercise of such Parent Option immediately prior to the Effective Time multiplied by (ii) the Option Exchange Ratio, and (b) the per share exercise price for the shares of Parent Stock issuable upon exercise of such Parent Option shall be equal to the quotient (rounded up to the next whole cent) obtained by dividing (i) the exercise price per Common Share at which such Parent Option was exercisable immediately prior to the Effective Time by (ii) the Option Exchange Ratio. For purposes hereof, the “Option Exchange Ratio” shall equal a ratio,

the numerator of which is the fair market value of one Common Share and the denominator of which equals the fair market value of one share of Parent Stock. No acceleration of the vesting of the unvested Company Options shall take place as a result of the consummation of the Merger, and the vesting terms and the expiration dates of the Parent Options shall be identical to the vesting terms and expiration dates of the Company Options. As of the Effective Time, Parent shall assume the Company Plan for the purpose of administering the Parent Options and shall amend and restate the Company Plan into the Parent Plan to, among other things, provide that (i) references to the Company shall be references to Parent, (ii) the Parent’s board of directors or a committee thereof shall succeed to the authority and responsibility of the Company board of directors or any committee thereof with respect to administration of the Company Plan and (iii) references to Common Shares shall be references to Parent Stock.

(c) The Company shall take all actions necessary in order to effect the provisions of this Section 3B including, without limitation, seeking all necessary approvals, providing any notice required under the terms of the Company Plan and/or the applicable agreements.

3C. Adjustments to Consideration. The consideration to be issued in connection with the conversion and cancellation of the Company Shares and the consideration to be issued in connection with the conversion and cancellation of the Company Options and Company SARs provided for in this Agreement shall be adjusted appropriately and proportionally to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into or exercisable or exchangeable for Parent Stock or Company Shares), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Parent Stock or Company Shares occurring or having a record date on or after the date hereof and prior to the Effective Time.

Section 4. Rights of Holders; Procedure for Exchange.

4A. Effect of Reorganization. Annex A attached hereto sets forth a calculation of the equity capitalization of Parent following the Blocker Mergers, the Contribution, the Merger, and the Restructuring. For the avoidance of doubt, it is the intention of the Company, the Parent, the Blocker Holders, and the other Holders that the Blocker Holders receive the same portion of the Parent Stock that the applicable Blockers of which they are Blocker Holders would receive in respect of the limited liability company interests in the Company held by them prior to the Restructuring as if the Blocker Holders held the limited liability company interests in the Company held by such Blockers and to the extent that the number of shares of Parent Stock issued to the Blocker Holders in the Restructuring does not effectuate the foregoing, then, to the fullest extent permitted by law, the determination and distribution of the Parent Stock shall be adjusted at the Effective Time to effect the foregoing.

4B. Rights of Holders of Certificates Evidencing Company Shares. On and after the Effective Time and until surrendered for exchange, each certificate that immediately prior to the Effective Time (and, for the avoidance of doubt, following the Contribution) represented Company Shares (except Company Shares cancelled or extinguished or converted into shares in the Surviving Company pursuant to Section 3A above) shall be deemed for all purposes to evidence ownership of and to represent solely the right to receive the number of whole shares of Parent Stock into which such Company Shares shall have been converted

pursuant to Section 3A above. In any matters relating to such certificates formerly representing Company Shares, Parent may rely conclusively upon the record of Members maintained by the Company containing the names and addresses of the holders of record of Company Shares as of immediately prior to the Effective Time.

4C. Procedure for Exchange of Company Shares.

(a) After the Effective Time, holders of certificates theretofore evidencing outstanding Company Shares (except shares cancelled or extinguished or converted into shares in the Surviving Company pursuant to Section 3A), upon surrender of such certificates to the secretary of Parent, shall be entitled to receive uncertificated book entry shares or certificates, to the extent the Parent Stock are certificated, representing the number of shares of Parent Stock into which Company Shares theretofore represented by the certificates so surrendered are exchangeable as provided in Section 3A hereof. Parent shall not be obligated to deliver any such Parent Stock to which any former holder of Company Shares is entitled until such holder surrenders the certificate or certificates representing such Company Shares. Upon surrender, each certificate formerly representing Company Shares shall be cancelled. If there is a transfer of Company Shares ownership which is not registered in the transfer records of the Company, a certificate representing the proper number of shares of Parent Stock may be issued to a Person other than the Person in whose name the certificate so surrendered is registered if: (x) upon presentation to the secretary of Parent, such certificate shall be properly endorsed or otherwise be in proper form for transfer, (y) the Person requesting such payment shall pay any transfer or other Taxes required by reason of the issuance of Parent Stock to a Person other than the registered holder of such certificate or establish to the reasonable satisfaction of Parent that such Tax has been paid or is not applicable, and (z) the issuance of such Parent Stock shall not, in the sole discretion of Parent, violate the requirements of the Regulation D “safe harbor” of the Securities Act with respect to the private placement of Parent Stock that will result from the Restructuring.

(b) All Parent Stock issued upon the conversion of Company Shares, in accordance with the above terms and conditions shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such Company Shares.

(c) With respect to each holder of outstanding Company Shares, the number of shares of Parent Stock receivable by such holder under this Agreement shall be aggregated for all Company Shares held by such holder, and, following such aggregation, any holder of Company Shares who would otherwise be entitled to receive a fraction of a share of Parent Stock shall, in lieu thereof, receive an amount in cash equal to the fair value of such fraction of a share as of the Effective Time as determined in good faith by the Board.

(d) Any Parent Stock issued pursuant to the Restructuring shall bear the legend required by the Registration Rights Agreement and otherwise be subject to the transfer limitations set forth therein.

Section 5. Conditions of the Obligations at the Effective Time.
