Section 2.4 Adjustment of a Portion of the Purchase Price. 

(a) As soon as practicable, but in no event more than ninety days, after the Closing Date, the Purchaser shall deliver to the Sellers’
Representative a statement (the “Closing Statement”) setting forth, in reasonable detail, its calculation of each of the Cash and the Working Capital (the “Adjustment Positions”). 

(b) Subject to the provisions of Section 2.4(c) and Section 2.4(d), the Sellers’ Representative will have thirty days from the
date of delivery of the Closing Statement to review and either approve or disapprove the Purchaser’s calculation of the Adjustment Positions as set forth in the Closing Statement. If the Sellers’ Representative approves the
Purchaser’s calculation of the Adjustment Positions, the Sellers’ Representative shall promptly so advise the Purchaser in writing. In the event that either (i) the Sellers’ Representative notifies the Purchaser within such
thirty day period that the Sellers’ Representative agrees with the Purchaser’s calculation of the Adjustment Positions or (ii) the Sellers’ Representative fails to provide any notification to the Purchaser with respect to such
Closing Statement within such thirty day period, then the Adjustment Positions as determined by the Purchaser and reflected in such Closing Statement will be deemed final. 

(c) If the Sellers’ Representative disagrees with the Purchaser’s calculation of the Adjustment Positions in the Closing Statement,
the Sellers’ Representative shall notify the Purchaser in writing (the “Notice of Disagreement”) of such disagreement within thirty days after delivery of the Closing Statement to the Sellers’ Representative. The Notice of
Disagreement will set forth in reasonable detail the basis for the disagreement. Thereafter, the Sellers’ Representative will work in good faith with the Purchaser to resolve and finally determine the calculation of the Adjustment Positions. If
the Sellers’ Representative and the Purchaser are able to resolve such disagreement within fifteen days after the delivery of the Notice of Disagreement, they shall jointly prepare a revised Closing Statement setting forth the agreed upon
Adjustment Positions and the Adjustment Positions as agreed upon by the Purchaser and the Sellers’ Representative and reflected in such revised Closing Statement will be deemed final. 

(d) If the Sellers’ Representative and the Purchaser are unable to resolve such disagreement within fifteen days after the delivery of the
Notice of Disagreement, the Sellers’ Representative and the Purchaser will appoint a mutually acceptable independent accounting firm recognized as expert in international accounting matters (the “Independent Accountant”) and
will each submit to the Independent Accountant a written submission (each, a “Submission”) setting forth such Party’s calculation of each of the Adjustment Positions and such Party’s positions on the issues in dispute. The
engagement of the Independent Accountant will specify that (i) the Independent Accountant shall act as an expert and not an arbitrator, (ii) it will accept as accurate all aspects of the calculation of the Adjustment Positions that have
not been identified as disputed items, (iii) it will make its determination based solely on the applicable provisions of this Agreement (and not independent review), (iv) it will base its determination solely on the Submissions (unless the
Independent Accountant requests additional information from either the 

  
 -7- 

 
Sellers’ Representative or the Purchaser), and not on independent investigation, (v) the Independent Accountant’s sole responsibility is to resolve the disputed items and provide
the Parties with a calculation of the Adjustment Positions based on the Parties’ resolution of the non-disputed items and the Independent Accountant’s resolution of the disputed items. The
Sellers’ Representative and the Purchaser shall deliver to the Independent Accountant all information reasonably requested by the Independent Accountant to resolve such disputed items and shall use commercially reasonable efforts to cause such
determination to be made, and written notice thereof given to the Sellers’ Representative and the Purchaser, within thirty days after such information is provided to the Independent Accountant. The determination by the Independent Accountant of
the disputed items will be final, binding and conclusive upon the Parties hereto, absent manifest error. The scope of the Independent Accountant’s engagement (which will not be an audit) will be limited to the resolution of the items identified
as disputed items in the Submissions. The fees, costs and expenses of the Independent Accountant, if any, will be paid (A) fully by the Purchaser if the Adjustment Positions as determined by the Independent Accountant are closer to the
calculation of the Adjustment Positions as set forth in the Sellers’ Representative’s Submission than the calculation of the Adjustment Positions as set forth in the Purchaser’s Submission (save as otherwise provided for in
(C) hereinafter), (B) fully by the Sellers’ Representative (from the Sellers’ Representative Expense Fund or by contributions from the Sellers) if the Adjustment Positions as determined by the Independent Accountant are closer to the
calculation of the Adjustment Positions as set forth in the Purchaser’s Submission than the calculation of the Adjustment Positions as set forth in the Sellers’ Representative’s Submission (save as otherwise provided for in
(C) hereinafter) and (C) 50% by the Purchaser and 50% by the Sellers’ Representative (from the Sellers’ Representative Expense Fund or by contributions from the Sellers) if the Adjustment Positions as determined by the Independent
Accountant are within USD 5,000 (five thousand US dollars) either side of the midway between the calculation of the Adjustment Positions as set forth in the Sellers’ Representative’s Submission and the calculation of the Adjustment
Positions as set forth in the Purchaser’s Submission. Notwithstanding any provision herein to the contrary, in the event that the Adjustment Positions are determined pursuant to this Section 2.4(d), then the Adjustment Positions shall be
calculated by giving effect to the matters not in dispute as resolved by the Sellers’ Representative and the Purchaser and giving effect to the Independent Accountant’s resolution of the matters in dispute, as reflected in a final report
by the Independent Accountant, which shall be binding upon the Parties in the absence of manifest error. 
 (e) For purposes of this
Agreement, the adjustments to the Purchase Price contemplated by this Section 2.4 (the “Purchase Price Adjustments”) shall be based on (i) the calculation of the Adjustment Positions as set forth in the Closing
Statement in the event that either (A) the Sellers’ Representative notifies the Purchaser within the thirty day period described in Section 2.4(b) that the Sellers’ Representative agrees with the Purchaser’s calculation of
the Adjustment Positions set forth in the Closing Statement or (B) the Sellers’ Representative fails to provide any notification to the Purchaser with respect to such Closing Statement within such thirty day period, (ii) the
calculation of the Adjustment Positions as agreed upon by the Purchaser and the Sellers’ Representative if agreement is reached by the Purchaser and the Sellers’ Representative pursuant to Section 2.4(c) and (iii) the calculation
of the Adjustment Positions identified in the last sentence of Section 2.4(d) as being the operative calculation in the event that the Adjustment Positions are determined pursuant to Section 2.4(d). For purposes of this Agreement,
(i) the terms “Final Cash” and “Final Working Capital” shall mean the calculations of the Cash and Working Capital, respectively, which, pursuant to this Section 2.4(e), are the calculations upon which the
Purchase Price Adjustments are to be based and (ii) the term “Final Determination Date” shall mean the seventh day after the date on which the Final Cash, the Final Working Capital and the Final Deferred Revenues are determined
hereunder. 

  
 -8- 

 (f) If the Final Cash is more than USD 2,090,000 (such surplus, a “Cash
Surplus”), then, by no later than the tenth Business Day after the Final Determination Date, the Purchaser will pay to the Sellers in cash an amount equal to 75% of the Cash Surplus, such payment to be made to the Sellers’ Solicitors
Client Account and allocated among the Sellers by reference to their respective fractional interests as set forth in Exhibit A annexed hereto (the “Fractional Interests”). 

(g) If the Final Working Capital is more than negative USD 7,070,888 (such surplus, a “Working Capital Surplus”), then, by no
later than the tenth Business Day after the Final Determination Date, the Purchaser will pay to the Sellers in cash an amount equal to 75% of the Working Capital Surplus, such payment to be made to the Sellers’ Solicitors Client Account and
allocated among the Sellers by reference to their respective Fractional Interests. For avoidance of doubt, if the Final Working Capital is negative USD 7,070,887, that is deemed to be USD 1 more than negative USD 7,070,888. 

(h) If the Final Cash is less than USD 1,710,000 (such deficit, a “Cash Deficit”), the Cash Deficit will reduce the number of
shares of Class A Stock issuable hereunder pursuant to Section 2.5(c)(iii). 
 (i) If the Final Working Capital is less than
negative USD 8,642,197 (such deficit, a “Working Capital Deficit”), the Working Capital Deficit will reduce the number of shares of Class A Stock issuable hereunder pursuant to Section 2.5(c)(iii). For avoidance of doubt,
if the Final Working Capital is negative USD 8,642,198, that is deemed to be USD 1 less than negative USD 8,642,197. 
 (j) This
Section 2.4 will not apply to the Optionholders. 
 Section 2.5 Issue of Class A Stock.  

(a) Subject to the limitations set forth in Section 2.5(c), the Purchaser will cause Parent to issue the following number of shares of
Class A Stock, allocated among the Principal Sellers and between the Principal Sellers and the Investment Firm (or its Affiliate) as set forth in Section 2.5(b), such shares of Class A Stock to be issued unencumbered, but subject to
the restrictions imposed pursuant to Rule 144 of the United States Securities and Exchange Commission and bearing the restrictive legend set forth in the footnote to Exhibit A annexed hereto: 

(i) a number of shares of Class A Stock (the “Forty Percent Shares”) equal to the quotient obtained by dividing
(x) USD 20,000,000, as such amount may be reduced pursuant to this Section 2.5 (such amount, as it may be reduced, the “Forty Percent Adjustable Amount”), by (y) the Average Market Price (such number of shares to be
rounded down to the nearest whole number), will be issued on the later of (aa) the date which is six calendar months after the Closing Date (or if that day is not a Business Day, the next following Business Day) and (bb) the date which is five
Business Days after the date, if any, on which the Purchaser is notified in writing by the Company or the Sellers’ Representative that there is a final, non-appealable dismissal with prejudice or
judgement that fully resolves the Texas Litigation in favor of the Company (in each case the “Forty Percent Release Date”); 

  
 -9- 

 (ii) a number of shares of Class A Stock (the “First Component of the
Sixty Percent Shares”) equal to the quotient obtained by dividing (x) USD 10,000,000, as such amount may be reduced pursuant to this Section 2.5 (such amount, as it may be reduced, the “First Anniversary Adjustable
Amount”), by (y) the Average Market Price (such number of shares to be rounded down to the nearest whole number), will be issued on the first anniversary of the Sixty Percent Release Date (or if such date is not a Business Day,
on the next following Business Day); 
 (iii) a number of shares of Class A Stock (the “Second Component of the Sixty
Percent Shares”) equal to the quotient obtained by dividing (x) USD 10,000,000, as such amount may be reduced pursuant to this Section 2.5 (such amount, as it may be reduced, the “Second Anniversary Adjustable
Amount”), by (y) the Average Market Price (such number of shares to be rounded down to the nearest whole number), will be issued on the second anniversary of the Sixty Percent Release Date (or if such date is not a Business Day,
on the next following Business Day); and 
 (iv) a number of shares of Class A Stock (the “Third Component of the Sixty
Percent Shares” and together with the First Component of the Sixty Percent Shares and the Second Component of the Sixty Percent Shares, the “Sixty Percent Shares”) equal to the quotient obtained by dividing (x) USD
10,000,000, as such amount may be reduced pursuant to this Section 2.5 (such amount, as it may be reduced, the “Third Anniversary Adjustable Amount”) by (y) the Average Market Price (such number of shares to be
rounded down to the nearest whole number), will be issued on the third anniversary of the Sixty Percent Release Date (or if such date is not a Business Day, on the next following Business Day). 

(b) On the dates when the Parent is required to issue shares of Class A Stock pursuant to Section 2.5(a), the Purchaser will cause
Parent to issue 95% of such shares (rounded down to the nearest whole number) to the Principal Sellers and the Purchaser will cause Parent to issue 5% of such shares (rounded down to the nearest whole number) to the Investment Firm (or its
Affiliate). The issuance of such shares to the Investment Firm (or its Affiliate) is made at the direction of the Sellers. With respect to the shares of Class A Stock issuable to the Principal Sellers, such shares will be allocated among the
Principal Sellers in accordance with the terms of the Operating Company Contribution Deed, any fractional interests will be ignored and only whole shares will be issued. The Principal Sellers shall provide, and shall cause the Investment Firm (or
its Affiliate) to provide, to the Purchaser and Parent such information as Parent shall require in order to direct its transfer agent to issue such shares. 

(c) Notwithstanding any provision in Section 2.5(a) or Section 2.5(b) to the contrary: 

  
 -10- 

 (i) In the event that (x) the result of the Pending Appeal or any further appeal of
the Texas Litigation is that Judge Gilstrap’s ruling in the United States District Court for the Eastern District of Texas in the Texas Litigation is reversed in whole or in part and such case is remanded to the United States District Court for
the Eastern District of Texas and (y) after such remand, there is a final non-appealable judgement with prejudice in favor of SAS, then (I) the Purchaser shall have no obligation to cause Parent to
issue, and Parent shall have no obligation to issue, any of the Forty Percent Shares (and the Purchaser will be released from its obligations under Section 2.5(a)(i)) and (II) the Purchaser shall have no obligation under
Section 2.5(a) to cause Parent to issue, and Parent shall have no obligation to issue, any of the Sixty Percent Shares which at the date of such final non-appealable judgement have not been issued or are
subject to any pending claims by the Purchaser in respect of Covered Matters in accordance with Section 2.5(c) (iv) or Section 6.2 at such time. 

(ii) In the event that by the date that is four years and six months after the Sixty Percent Release Date, there has not been a final, non-appealable dismissal with prejudice or judgement that fully resolves the Texas Litigation in favor of the Company, then the Purchaser shall have no obligation to cause Parent to issue, and Parent shall have no
obligation to issue, any of the Forty Percent Shares (and the Purchaser will be released from its obligations under Section 2.5(a)) or to cause Parent to issue, and Parent shall have no obligation to issue, any of the Sixty Percent Shares that
are subject to any pending claims by the Purchaser in respect of Covered Matters in accordance with Section 2.5(c)(iv) or Section 6.2 at such time.

Working Capital Deficit, if any, by an amount equal to 94.01% of the IP Company Cash Deficit, if any, and by an amount equal to 94.01% of the IP Company Working Capital Deficit, if any. If the sum of the Cash Deficit, if any, the Working Capital
Deficit, if any, 94.01% of the IP Company Cash Deficit, if any, and 94.01% of the IP Company Working Capital Deficit, if any, are greater than the First Anniversary Adjustable Amount, then any such excess shall reduce, in sequential order, the
Second Anniversary Adjustable Amount, the Third Anniversary Adjustable Amount and the Forty Percent Adjustable Amount. 
 (iv) The number of
shares of Class A Stock issuable in accordance with Section 2.5(a) will be adjusted by deducting, from the First Anniversary Adjustable Amount, the Second Anniversary Adjustable Amount, the Third Anniversary Adjustable Amount and/or the
Forty Percent Adjustable Amount, an amount equal to the aggregate of all liabilities for Covered Matters which are undischarged at the respective dates for issue of those shares pursuant to Section 2.5(a); provided, however, that no such
deduction shall be made with respect to the SAS Litigation Covered Matters after the date that is four years and six months after the Sixty Percent Release Date. For these purposes, the “Covered Matters” are the matters described in
the following clauses (A), (B), (C) and (D) and the “SAS Litigation Covered Matters” are the matters described in the following clauses (B), (C) and (D): 

(A) any indemnification claims made by the Purchaser in accordance with Section 6.2; 

(B) to the extent that the aggregate legal fees and properly incurred
out-of-pocket expenses incurred by the Company or the Parent (to the extent that such fees and expenses incurred by Parent are reasonably incurred) with respect to the
SAS Litigation exceed USD 300,000 (net of any Value Added Tax) in any Financial Year (the “Litigation Limit”), an amount equal to the excess over the Litigation Limit for each Financial Year provided, however, in calculating
the aggregate amount of such legal fees and expenses incurred by the Company or the Parent in any Fiscal Year, there shall be excluded the aggregate amount of Post Ninety Day Legal Fees and Expenses; 

  
 -11- 

 (C) an amount equal to the aggregate of any fines, penalties, damages, legal fees and

restricted in any way from doing business in the United States as a result of rulings arising from or related to the SAS Litigation. 
 The Purchaser shall
determine, in good faith, after taking into account any written representations made by the Sellers’ Representative, whether the liabilities associated with the Covered Matters shall reduce the First Anniversary Adjustable Amount, the Second
Anniversary Adjustable Amount, the Third Anniversary Adjustable Amount and/or the Forty Percent Adjustable Amount, provided that there is no duplication of reductions and provided that there is no recoupment with respect to shares of Class A
Stock once they are issued pursuant to Section 2.5(a) other than to the extent that there is liability pursuant to Section 6.2(d) for Damages beyond the value of shares of Class A Stock that are not yet issued pursuant to
Section 2.5(a). 
 (v) If, on any date on which shares of Class A Stock are otherwise to be issued in accordance with
Section 2.5(a), the Purchaser has made a written claim for indemnification under ARTICLE VI that has not been finally resolved pursuant to ARTICLE VI, then the U.S. dollar amount of such pending claim shall be deducted from and shall reduce the
First Anniversary Adjustable Amount, the Second Anniversary Adjustable Amount, the Third Anniversary Adjustable Amount and/or the Forty Percent Adjustable Amount (as determined by the Purchaser in its discretion but without duplication) when
determining the number of shares of Class A Stock (if any) to be issued on such date. If, following final determination or agreement by the Purchaser and the Sellers’ Representative of all such pending claims, an amount is payable by the
Purchaser, then a number of shares of Class A Stock equal to the quotient obtained by dividing (i) the amount so payable by (ii) the Average Market Price (the number of shares to be rounded down) will be issued in accordance with
Section 2.5(b) within ten Business Days after the last of such claims shall have been finally determined or agreed by the Purchaser and the Sellers’ Representative. 

(vi) The Purchaser will have no obligation to cause Parent to issue, and Parent will have no obligation to issue, any of the First Component
of Sixty Percent Shares to any Designated Employee who, on the first anniversary of the Sixty Percent Release Date, is no longer an employee of or consultant to the Company, the Purchaser or any of their respective Affiliates if such Designated
Employee’s employment or consultancy agreement was terminated either (A) by such Designated Employee without Good Reason or (B) by such Designated Employee’s employer or client for Cause. The Purchaser will have no obligation to
cause Parent to issue, and Parent will have no obligation to issue, any of the Second Component of Sixty Percent Shares to any Designated Employee who, on the second anniversary of the Sixty Percent Release Date, is no

  
 -12- 

 
longer an employee of or consultant to the Company, the Purchaser or any of their respective Affiliates if such Designated Employee’s employment or consultancy agreement was terminated
either (C) by such Designated Employee without Good Reason or (D) by such Designated Employee’s employer or client for Cause. The Purchaser will have no obligation to cause Parent to issue, and Parent will have no obligation to issue,
any of the Third Component of Sixty Percent Shares to any Designated Employee who, on the third anniversary of the Sixty Percent Release Date, is no longer an employee of or consultant to the Company, the Purchaser or any of their respective
Affiliates if such Designated Employee’s employment or consultancy agreement was terminated either (E) by such Designated Employee without Good Reason or (F) by such Designated Employee’s employer or client for Cause. Any shares
of Class A Common Stock that cease to be issuable to a Designated Employee pursuant to this Section 2.5(c)(vi) shall cease to be issuable pursuant to this Agreement. 

(vii) In the event that Parent enters into an agreement to consummate a Business Combination Event or otherwise consummates a Business
Combination Event prior to the time when the Purchaser ceases to have any further obligation to cause Parent to issue Class A Stock hereunder, then the Sellers’ Representative, the Purchaser and Parent shall concurrently enter into an
amendment to this Agreement, in form and substance reasonably satisfactory to the Purchaser and Parent, that provides that subsequent to the date of consummation of such Business Combination Event, in lieu of any further obligation to cause Parent
to issue any shares of Class A Stock hereunder, the Purchaser or the Purchaser’s successor shall be obligated to cause Parent or Parent’s successor to issue or pay Converted Units, at a ratio of one Converted Unit for each share of
Class A Stock that would have been issuable hereunder in the absence of such Business Combination Event, under terms comparable to the terms applicable to the issuance of Class A Stock hereunder. 

(d) Promptly after the Purchaser determines that a reduction is to be made in the Forty Percent Adjustable Amount, the First Anniversary
Adjustable Amount, the Second Anniversary Adjustable Amount or the Third Anniversary Adjustable Amount, the Purchaser shall provide the Sellers’ Representative with a notice describing such adjustment in reasonable detail and the Sellers’
Representative shall acknowledge receipt of such notice and provide a copy of such notice to each Principal Seller and the Investment Firm. 

(e) The relative equity ownership of each of the Sellers (excluding the interests of the Optionholders) is set forth in Exhibit A annexed
hereto under the column entitled “Fractional Interests”. The relative equity ownership of each of the Principal Sellers is set forth in Exhibit A annexed hereto under the column entitled “Amended Fractional Interests”)
(“Amended Fractional Interests”). The relative equity ownership of each of the Sellers in the IP Company is set forth in Exhibit B annexed hereto under the column entitled “IP Company Fractional Interests.” The relative
equity ownership of each of the Principal Sellers in the IP Company is set forth in Exhibit B annexed hereto under the column entitled “IP Company Amended Fractional Interests”) (“IP Company Amended Fractional Interests”).
The Fractional Interests differ slightly from the IP Company Fractional Interests, as do the Amended Fractional Interests and the IP Company Amended Fractional Interests. In connection with each reduction in the number of shares of Class A
Stock to be made pursuant to this Agreement, it shall be necessary to determine whether the reduction was occasioned pursuant to a provision in the IP Company Stock Sale and Purchase Agreement (in which case the reduction would be allocated among
the Principal Sellers in 

  
 -13- 

 
accordance with the IP Company Amended Company Fractional Interests) or whether the reduction was not occasioned pursuant to a provision in the IP Company Stock Sale and Purchase Agreement (in
which case the reduction would be allocated among the Principal Sellers in accordance with the Amended Fractional Interests). Each notice delivered pursuant to Section 2.5(d) shall also set forth the allocation of the reduction among the
Principal Sellers, computed in the manner set forth in this Section 2.5(e). Each time that shares of Class A Stock are to be issued hereunder, the Purchaser shall take into account each reduction in the shares of Class A Stock
applicable to such issuance and shall allocate the overall reduction in shares applicable to the Principal Sellers among the Principal Sellers based on how each reduction was allocated either on the basis of IP Company Amended Fractional Interests
or Amended Fractional Interests. The Purchaser shall provide the Sellers’ Representative with a notice describing how such overall allocation has been calculated in reasonable detail and the Sellers’ Representative shall acknowledge
receipt of such notice and provide a copy of such notice to each Principal Seller. A hypothetical example describing how the allocation of reductions among the Principal Sellers is to be calculated is set forth in Exhibit B annexed hereto. The
notifications provided to the Sellers’ Representative pursuant to Section 2.5(d) and this Section 2.5(e) shall be final and binding on the Sellers Representative, the Principal Sellers and the Investment Firm, absent mathematical
errors that are correctable and corrected prior to the issuance of shares of Class A Stock hereunder. 
 Section 2.6 Joint and
Several Liability. All obligations of the Sellers under Section 2.4 shall be joint and several. 
 Section 2.7 Closing.
Subject to compliance with the terms and conditions of this Agreement, the closing of the transactions contemplated hereby (the “Closing”) shall take place remotely via the exchange of documents and signatures concurrently with the
execution of this Agreement.

 (b) the minute books, Tax Returns, accountant work papers, and Share transfer records of the Company and its Subsidiaries,
provided that if documents and records are located at an office of the Company or its Subsidiaries on the Closing Date, the Sellers shall be deemed to have delivered such documents to the Purchaser;

(j) an agreement, among the Investment Firm, the Sellers’ Representative, the Purchaser and the Parent, pursuant to which the Investment
Firm shall (i) provide investment representations comparable to the representations made in Section 3.30, (ii) acknowledge that the payment of cash to the Investment Firm in accordance with the terms of this Agreement and the IP Company
Stock Sale and Purchase Agreement and the issuance of Class A Stock to the Investment Firm (or its Affiliate) in accordance with the terms of this Agreement constitute payment in full for all services rendered by the Investment Firm to the
Company Group, the IP Company Group and their respective equity owners, (iii) acknowledge that the issuance of Class A Stock to the Investment Firm (or its Affiliate) shall be governed exclusively by the applicable provisions of this
Agreement relating thereto, (iv) acknowledge that the Investment Firm shall be bound by all determinations made by the Sellers’ Representative with respect to the matters described in Article II and Article VI of this Agreement; and 

(k) all other documents required to be delivered by the Sellers or the Sellers’ Representative to the Purchaser pursuant to this Agreement
or reasonably necessary to give effect to the transactions contemplated under this Agreement. 
 Section 2.9 Post-Closing

the Company is in good standing in the jurisdiction of its organization.

(a) Notwithstanding anything to the contrary in this Agreement, the Purchaser may, but is not required to, file an election pursuant to
Section 338(g) of the Code with respect to the Purchaser’s acquisition of the entities in the Company Group. 
 (b) All stock
transfer, documentary, stamp duty, sales, use, registration and other similar Taxes, and all conveyance fees, recording charges, and other fees and charges (including interest, penalties and additions to any such Taxes) incurred in connection with
the consummation of the transactions contemplated by this Agreement (“Transfer Taxes”) shall be paid by the Sellers when due, and the Sellers will, at their own expense, file all necessary Tax Returns and other documentation with
respect to all such Transfer Taxes. If required by applicable Law, the Purchaser will, and will cause its Affiliates to, join in the execution of any such Tax Returns and other documentation. The Parties shall cooperate, and shall cause their
respective Affiliates to cooperate in good faith to minimize the amount of any applicable Transfer Taxes. 
 (c) Purchaser, at the sole cost
and expense of Sellers, shall prepare and file, or cause to be prepared and filed, all Tax Returns of the entities in the Company Group for any for Pre-Closing Periods and Straddle Periods, in each case, the
due date of which (after taking into account any valid extensions of time to file) is after the Closing Date. The Sellers shall reimburse and indemnify Purchaser or its designee, on a joint and several basis, for all amounts shown due on the Tax
Returns filed pursuant to this Section 5.5(c) to the extent attributable to any Pre-Closing Period or the portion of any Straddle Period ending at the closing of business on the Closing Date (determined
as provided in Section 6.2(a)). Each of the Sellers and the Sellers’ Representative shall cooperate fully, as and to the extent reasonably requested by the Purchaser or the Company Group, in connection with the preparation and filing of
any Tax Return. Such cooperation shall include the retention and, upon request, the provision of records and information which are reasonably relevant to any such Tax Return. 

(d) All amounts which become payable pursuant to Section 2.4 or Section 2.5, and any payment made pursuant to Article VI shall
constitute an adjustment to the Purchase Price for applicable Tax purposes, to the extent permitted by applicable Law. 
 Section 5.6
SAS Directed Receivables. The Purchaser shall cause the Company to use reasonable commercial efforts to cause the SAS Directed Receivables to be collected as promptly as possible. Promptly after the 120th day following the date hereof and in any event no later than twenty Business Days thereafter (the “Determination Date”), the Purchaser shall determine in good faith (and in
accordance with customer instructions, where applicable) the dollar amount of SAS Directed Receivables that were paid, either to reduce the Existing Judgement or directly to the Company, during the period from the date hereof through the 120th day after the date hereof (the “Receivables Amount”). No later than five Business Days falling after the Determination 

  
 -45- 

 
Date, the Purchaser shall provide the Sellers’ Representative with a statement setting forth such dollar amount by customer, which statement shall be binding upon the Principal Sellers and
the Sellers’ Representative absent manifest error. Promptly after providing such statement to the Sellers’ Representative and in any event no later than fifteen Business Days thereafter, the Purchaser shall pay the Receivables Amount to
the Sellers’ Solicitors Client Account for allocation among the Principal Sellers on the basis of their respective Amended Fractional Interests. 

ARTICLE VI 
 Survival of
Warranties and Covenants; Indemnification 
 Section 6.1 Survival of Warranties. Subject to the limitations and other
provisions of this Agreement, the warranties provided for in this Agreement and the warranties provided for in the IP Company Stock Sale and Purchase Agreement will survive the Closing for a period of two years from the Closing Date for the benefit
of the Parties hereto and their successors and assigns, at which point they will expire, except that (i) the IP Warranties, the warranties referred to as the “IP Warranties” in the IP Company Stock Sale and Purchase Agreement and the
SAS Warranties will survive the Closing for a period of four years from the Closing Date for the benefit of the Purchaser, at which point they will expire, (ii) the Fundamental Warranties (other than Tax Warranties) and the warranties referred
to as the “Fundamental Warranties” in the IP Company Stock Sale and Purchase Agreement (other than the warranties referred to as “Tax Warranties” in the IP Company Stock Sale and Purchase Agreement) will survive the Closing for a
period of five years from the Closing Date for the benefit of the Purchaser, at which point they will expire, and (iii) the liability of the Sellers in respect of warranties referenced in Section 3.12 or in Section 3.12 of the IP
Company Stock Sale and Purchase Agreement or elsewhere in this Agreement or the IP Company Stock Sale and Purchase Agreement regarding (a) Taxes, social security or similar obligations arising out of events occurring on or prior to the Closing
Date whether or not provided for or disclosed in the Financial Statements or in the financial statements of the IP Company or its Subsidiaries, or (b) Taxes arising out of or in connection with any asset sales or other transfers,
reorganizations, or recapitalizations involving the Company Group, the IP Company or its Subsidiaries arising prior to or contemporaneously with the Closing (collectively, the “Tax Warranties”) shall survive until the statute of
limitation period expires with respect to such Taxes, social security or similar obligations. Any claim must be brought if at all within such applicable limitation periods. The survival period of each warranty as provided in this Section 6.1 or
otherwise provided at law, is hereinafter referred to as the “Survival Period.” Any claim for indemnification not made by a Party on or prior to the last day of the applicable Survival Period shall be irrevocably and unconditionally
released and waived; provided, however, that any obligation to indemnify and hold harmless under this Article VI shall not terminate with respect to any Damages for which the indemnified Party timely asserts a claim for indemnification with
reasonable specificity and in writing by notice to the indemnifying Party in accordance herewith before the termination of the applicable Survival Period and that claim will survive until finally resolved. For the avoidance of doubt, it is the
express intent of the Parties hereto that (i) if the applicable Survival Period for a matter contemplated by this Article VI is longer than the statute of limitations that would otherwise have been applicable to such matter, then, by contract,
the applicable statute of limitations with respect to such matter shall be extended to the longer Survival 

  
 -46- 

 
Period contemplated hereby and (ii) if the applicable Survival Period for a matter contemplated by this Article VI is shorter than the statute of limitations that would otherwise have been
applicable to such matter, then, by contract, the shorter Survival Period contemplated hereby shall apply. The Parties further acknowledge that the applicable Survival Periods set forth in this Section 6.1 for the assertion of claims or
bringing of actions under this Agreement are the result of arm’s-length negotiation between the Parties and that the Parties intend for the time periods to be enforced as agreed by the Parties. 

Section 6.2 Indemnification. 

(a) Effective upon consummation of the Closing and subject to the limitations set forth in Section 6.2(d), the Principal Sellers, jointly
and severally (save unless otherwise stated in Section 6.2(c)), shall indemnify and hold harmless the Purchaser, its Affiliates, and their respective officers, directors, employees, agents and representatives, and any Person claiming by or
through any of them (the “Purchaser Indemnified Parties”), against and in respect of Damages arising out of, resulting from or incurred in connection with: 

(i) any breach of any warranty made by the Sellers in this Agreement and any breach of any warranty made by the IP Company Sellers under the
IP Company Stock Sale and Purchase Agreement; 
 (ii) any and all Taxes (or the non-payment thereof)
of the Company Group or the IP Company Group (x) resulting from or by reference to any income, profits or gains arising or event occurring in any Pre-Closing Period, and in the portion of any Straddle
Period ending at the closing of business on the Closing Date (determined as provided in this Section 6.2(a)), including, for the avoidance of doubt, any such Taxes for which the Sellers or the IP Company Sellers are responsible, as provided in
Section 5.5(b) or in Section 5.5(b) of the IP Company Stock Sale and Purchase Agreement, or (y) arising from the transactions contemplated by this Agreement or the IP Company Stock Sale and Purchase Agreement, including, for the
avoidance of doubt, any Transfer Taxes for which the Sellers are responsible, as provided in Section 5.5(b), or for which the IP Company Sellers are responsible, as provided in Section 5.5(b) of the IP Company Stock Sale and Purchase
Agreement; 
 (iii) any Long-Term Indebtedness of the Company Group as of the Closing Date that is not accurately reflected in the Closing
Certificate and any IP Company Long-Term Indebtedness of the IP Company Group as of the Closing Date that is not accurately reflected in the IP Company Closing Certificate; 

(iv) any Company Group Transaction Expenses unpaid as of the Closing Date that are not accurately reflected in the Closing Certificate and any
IP Company Group Transaction Expenses unpaid as of the Closing Date that are not accurately reflected in the IP Company Closing Certificate; 

(v) any Company Group Change in Control Payments that are not accurately reflected in the Closing Certificate and any IP Company Group Change
in Control Payments that are not accurately reflected in the IP Company Closing Certificate; 

  
 -47- 

 (vi) any unpaid interest or principal outstanding on the Insider Loans as of the Closing
Date that are not accurately reflected in the Closing Certificate and any unpaid interest or principal outstanding on the IP Company Insider Loans as of the Closing Date that are not accurately reflected in the IP Company Closing Certificate; 

(vii) any Investment Firm Closing Fees and Expenses that are not accurately reflected in the Company Closing Certificate or the IP Company
Closing Certificate and any other claims for compensation or reimbursement by the Investment Firm that are not expressly provided for in this Agreement or the IP Company Stock Sale and Purchase Agreement; and 

(viii) any amount payable with respect to the Optionholders to acquire their Option Shares in excess of the Optionholders’ Aggregate
Amount set forth in the Company Closing Date. 
 The Sellers acknowledge that in this Agreement they are providing indemnification to the
Purchaser with respect to matters arising under the IP Company Stock Sale and Purchase Agreement and agree to do so. The Purchaser Indemnified Parties shall not be entitled to recover Damages from the Sellers for any claim for indemnification
pursuant to Section 6.2(a) made after the expiration of the applicable Survival Period, provided that this sentence shall have no bearing on any such claim that is first made prior to the expiration of the applicable Survival Period. The Taxes,
if any, attributable to a Straddle Period shall be allocated (i) to the Sellers for the period up to and including the close of business on the Closing Date, and (ii) to the Purchaser for the period subsequent to the Closing Date. Any
allocation of income or deductions required to determine any Taxes attributable to a Straddle Period shall be made by means of a closing of the books and records of the Company Group and the IP Company Group as of the close of business on the
Closing Date; provided, that exemptions, allowances or deductions that are calculated on an annual basis (including, but not limited to, depreciation and amortization deductions) shall be allocated between the period ending on the Closing Date and
the period after the Closing Date in proportion to the number of days in each such period. In the case of any Taxes of the Company Group or the IP Company Group imposed on a periodic basis (including real property and ad valorem Taxes), the
allocation between the Sellers and the Purchaser shall be made based on the number of days during the Straddle Period on or before the Closing Date, on the one hand, and the number of days in the Straddle Period after the Closing Date, on the other
hand. 
 (b) Any Person providing indemnification pursuant to the provisions of Section 5.1(b) or this Section 6.2 is hereinafter
referred to as an “Indemnifying Party” and any Person entitled to be indemnified pursuant to the provisions of Section 5.1(b) or this Section 6.2 is hereinafter referred to as an “Indemnified Party.” 

(c) Effective upon consummation of the Closing, Peter Quarendon, Kevin Weekes and Benjamin Scurr shall each (on a several basis) indemnify and
hold harmless the Purchaser Indemnified Parties, against and in respect of Damages arising out of, resulting from or incurred in connection with any breach of Sections 3.1(c), 3.3, 3.4, 3.8 or 3.12(w) of this Agreement or the last sentence of
Section 3.6 of this Agreement or Sections 3.1(c), 3.3, 3.4, 3.8 or 3.12(w) of the IP Company Stock Sale and Purchase Agreement or the last sentence of Section 3.6 of the IP Company Stock Sale and Purchase Agreement by each of Peter
Quarendon, Kevin 

  
 -48- 

 
Weekes and Benjamin Scurr with respect to themselves only (i.e. on a several basis), subject to each of Peter Quarendon’s, Kevin Weekes’s and Benjamin Scurr’s Liability Cap. Such
Damages shall be payable within twenty Business Days after a determination is made, either pursuant to arbitration in accordance with Section 7.4 or pursuant to agreement by the Sellers’ Representative and the Purchaser. For each of Peter
Quarendon, Kevin Weekes and Benjamin Scurr, the term “Liability Cap” means the aggregate consideration theretofore paid to each of Peter Quarendon, Kevin Weekes and Benjamin Scurr under this Agreement and the IP Company Stock Sale
and Purchase Agreement. 
 (d) The Principal Sellers’ indemnification obligations set forth in Section 6.2(a) shall be subject to
the following limitations: 
 (i) The Principal Sellers’ indemnification obligation set forth in Section 6.2(a)(i), with respect
to General Warranties, IP Warranties and the warranties referred to as “General Warranties” and “IP Warranties” under the IP Company Stock Sale and Purchase Agreement shall not apply to any claims for Damages unless and until
such Damages exceed USD 50,000 (“Claims Threshold”), in which case the Principal Sellers shall be required to pay or be liable for all such Damages from the first dollar of such Damages irrespective of the Claims Threshold. For the
avoidance of doubt, claims made pursuant to Section 6.2(a)(i) with respect to Fundamental Warranties and warranties referred to as “Fundamental Warranties” under the IP Company Stock Sale and Purchase Agreement are not subject to the
limitations set forth in this Section 6.2(d)(i) and claims against a Party resulting from or related to fraud by that Party are not subject to the limitations set forth in this Section 6.2(d)(i). 

(ii) Except with respect to claims based on fraud, (A) Purchaser’s sole recourse for claims under Section 6.2(a)(i) with
respect to General Warranties, with respect to warranties referred to as “General Warranties” under the IP Company Stock Sale and Purchase Agreement and with respect to SAS Litigation Covered Matters shall be to the shares of Class A
Stock which have yet to be issued accordance with Section 2.5(a) at the time such claims are first made and (B) with respect to claims made under Section 6.2(a)(i) relating to IP Warranties, warranties referred to as “IP
Warranties” under the IP Company Stock Sale and Purchase Agreement, SAS Warranties, Fundamental Warranties, warranties referred to as “Fundamental Warranties” under the IP Company Stock Sale and Purchase Agreement and claims made
under Sections 6.2(a)(ii), 6.2(a)(iii), 6.2(a)(iv), 6.2(a)(v), 6.2(a)(vi), 6.2(a)(vii) and 6.2(a)(viii) of this Agreement or Sections 6.2(a)(ii), 6.2(a)(iii), 6.2(a)(iv), 6.2(a)(v), Section 6.2(a)(vi) or 6.2(a)(vii) of the IP Company Stock Sale
and Purchase Agreement, (I) Purchaser’s initial recourse shall be to the shares of Class A Stock which have yet to be issued in accordance with Section 2.5(a) at the time such claims are first made and (II) if the value of
such shares (based on the Average Market Price) is insufficient to cover the dollar amount of any such claims, 95% of the balance of such claims shall be recoverable by the Purchaser from the Principal Sellers on a joint and several basis, subject
to each Principal Seller’s “Liability Cap” if applicable, and 5% of the balance of such claims shall be recoverable from the Investment Firm, subject to the Investment Firm’s Liability Cap. For each Principal Seller who is not a
Designated Employee and who has not committed fraud, the term “Liability Cap” means the aggregate consideration theretofore paid to such Principal Seller hereunder and under the IP Company Stock Sale and Purchase Agreement
(consisting of the cash paid at Closing under this Agreement, the cash paid at the closing under the IP Company Stock Sale and Purchase Agreement and the shares of Class A Stock issued to such 

  
 -49- 

 
Principal Seller hereunder, valued at a per share price equal to the Average Market Price) and the aggregate consideration then payable to such Principal Seller hereunder (consisting of the
shares of Class A Stock remaining issuable to such Principal Seller, valued at a per share price equal to the Average Market Price). For each Principal Seller who is a Designated Employee and who has not committed fraud, the term
“Liability Cap” means the aggregate consideration theretofore paid to such Principal Seller hereunder (consisting of the cash paid at Closing and the shares of Class A Stock issued to such Principal Seller hereunder, valued at
a per share price equal to the Average Market Price), the cash paid to such Principal Seller at the closing under the IP Company Stock Sale and Purchase Agreement and the aggregate consideration then payable to such Principal Seller hereunder
(consisting of the shares of Class A Stock remaining issuable to such Principal Seller hereunder, valued at a per share price equal to the Average Market Price). For the Investment Firm, the term “Liability Cap” means the
aggregate consideration theretofore paid to the Investment Firm hereunder and under the IP Company Stock Sale and Purchase Agreement (consisting of the cash paid at Closing under this Agreement, the cash paid at the closing under the IP Company
Stock Sale and Purchase Agreement and the shares of Class A Stock issued to the Investment Firm (or its Affiliate) hereunder, valued at a per share price equal to the Average Market Price) and the aggregate consideration then payable to the
Investment Firm (or its Affiliate) hereunder (consisting of the shares of Class A Stock remaining issuable to the Investment Firm (or its Affiliate), valued at a per share price equal to the Average Market Price). For each Principal Seller who
has committed fraud, there shall be no Liability Cap and no restriction on Purchaser’s recourse to recover on claims made by the Purchaser hereunder. 

(e) Samuel Manning does not own any of the outstanding capital stock of the Company and owns 5.99% of the outstanding capital stock of the IP
Company. Inasmuch as Samuel Manning is not subject to indemnification claims under this Agreement and will not receive any shares of Class A Stock under this Agreement or the IP Company Stock Sale and Purchase Agreement, in calculating Damages
hereunder with respect to an indemnification matter that arises solely under the IP Company Stock Sale and Purchase Agreement, the amount recoverable by the Purchaser shall equal 94.01% of the actual Damages. 

(f) Notwithstanding anything in this Agreement to the contrary, there shall be no duplication of recovery with respect to any matter for which
indemnification is claimed pursuant to this Article VI and any matter for which indemnification is claimed under the IP Company Stock Sale and Purchase Agreement and any of the ancillary agreements delivered hereunder or thereunder. 

(g) Effective upon consummation of the Closing, the Purchaser shall indemnify and hold harmless the Sellers and any Person claiming by or
through any of them, against and in respect of all Damages arising out of, resulting from or incurred in connection with any breach of any warranty made by the Purchaser in this Agreement. 

Section 6.3 Procedures for Claims. 

(a) In the case of any claim for indemnification arising from a claim of a third party (a “Third Party Claim”), an Indemnified
Party shall give prompt written notice, following such Indemnified Party’s receipt of such claim or demand, to the Indemnifying Party of any claim or demand of which such Indemnified Party has knowledge and as to which it may request

  
 -50- 

 
indemnification hereunder (a “Third Party Claim Notice”); provided, however, that failure to give such notice will not affect such Indemnified Party’s rights
furnished hereunder unless, and then solely to the extent that, the rights of the Parties from whom indemnity is sought are materially prejudiced as a result of such failure. The Indemnifying Party shall have the right to defend and to direct the
defense against any such claim or demand, in its name or in the name of the Indemnified Party, as the case may be, at the expense of the Indemnifying Party, and with counsel selected by the Indemnifying Party that is acceptable to the Indemnified
Party (such acceptance not to be unreasonably withheld, conditioned or delayed) unless (i) such claim or demand seeks an order, injunction or other equitable relief against the Indemnified Party, (ii) upon assumption of the defense, the
Indemnifying Party fails to acknowledge in writing to the Indemnified Party its indemnity obligations with respect to the full amount of Damages from such Third Party Claim without deduction, set-off or
counterclaim hereunder (except for the express limitations set forth in this Agreement) and its obligations to hold harmless the Indemnified Parties therefrom or (iii) the Indemnified Party shall have reasonably concluded that (x) there is
a conflict of interest between the Indemnified Party and the Indemnifying Party in the conduct of the defense of such claim or demand, (y) the Indemnified Party has one or more defenses not available to the Indemnifying Party or (z) if the
Indemnified Party is a Purchaser Indemnified Party, the underlying matter is a criminal matter, is a matter that pertains to the SAS Litigation, is a matter that reasonably could be expected to impact the business reputation of the Purchaser, Parent
or any of their Subsidiaries or is a matter that reasonably could, if the Third Party Claim is sustained, be expected to adversely impact (I) any Tax position with respect to any Tax period (or portion thereof) beginning after the Closing Date
or (II) the Intellectual Property, in each case, of the Company Group, of the IP Company Group, of the Purchaser or of any other Affiliate of the Purchaser. Notwithstanding anything in this Agreement to the contrary, the Indemnified Party
shall, at the expense of the Indemnifying Party, cooperate with the Indemnifying Party, and keep the Indemnifying Party fully informed, in the defense of such claim or demand. The Indemnified Party shall have the right to participate in the defense
of any claim or demand with counsel employed at its own expense; provided, however, that, in the case of any claim or demand described in clause (i) or (ii) of the second preceding sentence or as to which the Indemnifying Party shall not
in fact have employed counsel that is acceptable to the Indemnified Party (such acceptance not to be unreasonably withheld, conditioned or delayed) to assume the defense of such claim or demand, the reasonable fees and disbursements of the
Indemnified Party’s counsel shall be at the expense of the Indemnifying Party, except as otherwise provided in Section 2.5(c)(iv)(B). The Indemnifying Party shall have no indemnification obligations with respect to any such claim or demand
which shall be settled by the Indemnified Party without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. The Indemnifying Party shall not settle any such claim without the
prior written consent of the Indemnified Party, unless (A) such settlement is accompanied by a document releasing the Indemnified Party from all liability with respect to the matter in controversy, (B) such settlement shall not limit,
damage or interfere with the continuing operation of the Business in any respect and (C) if the Indemnified Party is a Purchaser Indemnified Party, such settlement shall not involve a criminal matter, a matter that pertains to the SAS
Litigation, a matter that reasonably could be expected to impact the business reputation of the Purchaser, Parent or any of their Subsidiaries or a matter that reasonably could be expected to adversely impact the Intellectual Property of the Company
Group, of the IP Company Group, of the Purchaser or of any Affiliate of the Purchaser. For purposes of determining whether notice has been provided hereunder within an applicable Survival Period, notice shall be deemed to have been given on the date
that the Third Party Claim Notice is deemed received pursuant to Section 7.1. 

  
 -51- 

 (b) In the event that an Indemnified Party determines that it has a claim for Damages
against an Indemnifying Party hereunder (other than as a result of a Third Party Claim) (an “Interparty Claim”), the Indemnified Party shall give prompt written notice thereof to the Indemnifying Party, specifying the amount of such
claim, the section of this Agreement under which such claim arises and any other relevant facts and circumstances relating thereto (an “Interparty Claim Notice”); provided, however, that failure to give such notice
promptly will not affect such Indemnified Party’s rights furnished hereunder unless, and then solely to the extent that, the rights of the Parties from whom indemnity is sought are materially prejudiced as a result of such failure The
Indemnified Party shall provide the Indemnifying Party with reasonable access to its books and records for the purpose of allowing the Indemnifying Party a reasonable opportunity to verify any such claim for Damages. The Indemnified Party and the
Indemnifying Party shall negotiate in good faith for a thirty day period (beginning on the date the Indemnified Party provides an Interparty Claim Notice hereunder) regarding the resolution of any disputed claims for Damages. If no resolution is
reached with regard to such disputed Interparty Claim between the Indemnifying Party and the Indemnified Party within such thirty day period, the Indemnified Party shall be entitled to seek appropriate remedies in accordance with the terms hereof.
For purposes of determining whether notice has been provided hereunder within an applicable Survival Period, notice shall be deemed to have been given on the date that the Interparty Claim Notice is deemed received pursuant to Section 7.1. 

(c) Promptly following a final determination of the amount of any Damages claimed by the Indemnified Party by either (i) a determination
of an arbitrator pursuant to Section 7.3 or (ii) the mutual agreement by the Indemnified Party and Indemnifying Party, the following shall occur: 

(i) If, after giving effect to the limitations set forth in Section 6.2(d), the Purchaser has the right to recover Damages in respect of
any claims made under Section 6.2(a)(i) relating to General Warranties or warranties referred to as “General Warranties” under the IP Company Stock Sale and Purchase Agreement or has a right to a recovery hereunder with respect to SAS
Litigation Covered Matters, by way of enforcement against the issue of shares of Class A Stock in accordance with Section 2.5(a) which at the time any such claim is first made have not been issued, the Purchaser shall have the right to
recover such Damages by reducing the number of shares of Class A Stock issuable hereunder in accordance with Section 2.5(c). 

(ii) If, after giving effect to the limitations set forth in Section 6.2(d), the Purchaser has the right to recover Damages in respect of
any claims made under Section 6.2(a)(i) relating to IP Warranties, warranties referred to as “IP Warranties” under the IP Company Stock Sale and Purchase Agreement, SAS Warranties, Fundamental Warranties and warranties referred to as
“Fundamental Warranties” under the IP Company Stock Sale and Purchase Agreement and any claims made under Sections 6.2(a)(ii), 6.2(a)(iii), 6.2(a)(iv), 6.2(a)(v), 6.2(a)(vi), 6.2(a)(vii) and 6.2(a)(viii) of this Agreement or Sections
6.2(a)(ii), 6.2(a)(iii), 6.2(a)(iv), 6.2(a)(v), 6.2(a)(vi) and 6.2(a)(vii) of the IP Company Stock Sale and Purchase Agreement, the Purchaser shall have the right to reduce the number of shares of Class A Stock issuable hereunder in accordance
with Section 2.5(c) and Section 6.2(c) to recover such Damages and, to the extent permitted by Section 6.2(d), to proceed directly against the Principal Sellers and Investment Firm to recover such Damages.

 Section 7.2 Expenses. Except as otherwise provided herein, each Party shall pay its own expenses
incident to this Agreement and the transactions contemplated hereby and the Sellers shall pay all expenses of the Sellers’ Representative and each entity in the Company Group relating hereto. 

Section 7.3 Payments. 

(a) Cash payments to be made to the Sellers under this Agreement, including any payment by the Sellers’ Representative from the
Sellers’ Representative Expense Fund should the Sellers’ Representative determine that the Sellers’ Representative no longer requires any of the money held in the Sellers’ Representative Expense Fund, will be made
by electronic transfer of immediately available funds to the Sellers’ Solicitors Client Account or to any other single client account in the United Kingdom of a reputable law firm of which the Sellers’ Representative gives the Purchaser at
least three business days’ notice from time to time. 
 (b) Payment of any sum to: 

(i) the Sellers’ Solicitors Client Account or otherwise in accordance with Section 7.3(a); 

(ii) any account details of which are provided in the Closing Certificate; or 

(iii) any account of an Optionholder details of which are provided to the Purchaser by the Sellers’ Representative or the Sellers’
Solicitors; 
 will discharge the obligations of the Purchaser to pay the sum in question and the Purchaser is not concerned to see the application of the
monies so paid. 
 (c) Payments to be made to the Purchaser under this Agreement will be made in US dollars calculated at the exchange rate
quoted by the Bank of England for the conversion of pounds into US dollars at midday on the day before the due date for payment, by electronic transfer of immediately available fund to an account of the Purchaser of which the Purchaser gives at
least three business days’ notice. 
 (d) If 

  
 -54- 

 (i) any deduction of or withholding is required by law to be made from any sum payable by
any Seller to the Purchaser under this Agreement, the Seller shall pay such increased sum as will, after the deduction or withholding has been made, leave the Purchaser with the same amount as it would have been entitled to receive in the absence of
such requirement to make a deduction or withholding; and 
 (ii) any sum paid or payable to the Purchaser under this Agreement

(ii) There shall be one arbitrator, selected in accordance with the Rules. 

(iii) The arbitrator shall be skilled in the field of intellectual property law, applicable governing law and the other legal and business

(iv) Barring extraordinary circumstances, the arbitrator shall render an award within four months from the date on which the arbitrator is
selected. The arbitrator may extend this time limit in the interests of justice. Failure to adhere to this time limit shall not constitute a basis for challenging the award. 

(v) The parties shall be entitled to discovery in the arbitration except that any party shall be entitled to request no more than 1,000 pages
of documents and to take no more than three depositions not to exceed four hours for each such deposition. Any party shall be entitled to depose any expert who will testify in the arbitration proceeding but shall pay the regular hourly rate of such
expert during such deposition. In addition to the foregoing, any party shall be entitled to take the deposition of a witness who will testify at the arbitration but who is unavailable to testify at the hearing to preserve such witness’
testimony for the arbitration hearing.

law to support the arbitrator’s award. The award shall be final and binding upon the parties hereto, and shall be the sole and exclusive remedy among the parties hereto regarding any claims, counterclaims, issues, or accounting presented to the

 (x) Judgement upon the award of the arbitrator may be entered in any court having
jurisdiction thereof or such court may be asked to confirm judicially the award and order its enforcement, as the case may be. 
 (xi) Each
of the parties hereto shall bear its own attorney’s fees, costs and expenses and an equal share of the arbitrator’s fees and administrative fees of the arbitration. The parties agree that failure or refusal of a party to pay its required

argument as the arbitrator may require for the making of an award. 
 (xii) Except as may be required by law, neither a Party nor its
representatives may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of all Parties.

the Purchaser’s payment obligations under this Agreement, but subject to the same limitations as those on the Purchaser’s obligations hereunder. The Parent’s obligations are unconditional irrespective of any circumstances which might
otherwise constitute, by operation of law, a discharge of a guarantor or surety and it shall not be necessary for the Sellers to institute or exhaust any remedies or causes of action against the Purchaser or any other Person as a condition to the
obligations of Parent hereunder. Except as provided in this Agreement, Parent hereby irrevocably waives any right to receive a formal notification or to request that any other formalities or protest be accomplished in connection with its obligations
hereunder.

 (a) pay the Closing Cash Payment Amount to the Sellers’ Solicitors client account
(“Sellers’ Solicitors Client Account”) for allocation among the Sellers, in accordance with wire transfer instructions set forth in the Closing Certificate;

Section 2.4 Adjustment of a Portion of the Purchase Price. 

(a) As soon as practicable, but in no event more than ninety days, after the Closing Date, the Purchaser shall deliver to the Sellers’
Representative a statement (the “Closing Statement”) setting forth, in reasonable detail, its calculation of each of the Cash and the Working Capital (the “Adjustment Positions”). 

(b) Subject to the provisions of Section 2.4(c) and Section 2.4(d), the Sellers’ Representative will have thirty days from the
date of delivery of the Closing Statement to review and either approve or disapprove the Purchaser’s calculation of the Adjustment Positions as set forth in the Closing Statement. If the Sellers’ Representative approves the
Purchaser’s calculation of the Adjustment Positions, the Sellers’ Representative shall promptly so advise the Purchaser in writing. In the event that either (i) the Sellers’ Representative notifies the Purchaser within such
thirty day period that the Sellers’ Representative agrees with the Purchaser’s calculation of the Adjustment Positions or (ii) the Sellers’ Representative fails to provide any notification to the Purchaser with respect to such
Closing Statement within such thirty day period, then the Adjustment Positions as determined by the Purchaser and reflected in such Closing Statement will be deemed final. 

(c) If the Sellers’ Representative disagrees with the Purchaser’s calculation of the Adjustment Positions in the Closing Statement,
the Sellers’ Representative shall notify the Purchaser in writing (the “Notice of Disagreement”) of such disagreement within thirty days after delivery of the Closing Statement to the Sellers’ Representative. The Notice of
Disagreement will set forth in reasonable detail the basis for the disagreement. Thereafter, the Sellers’ Representative will work in good faith with the Purchaser to resolve and finally determine the calculation of the Adjustment Positions. If
the Sellers’ Representative and the Purchaser are able to resolve such disagreement within fifteen days after the delivery of the Notice of Disagreement, they shall jointly prepare a revised Closing Statement setting forth the agreed upon
Adjustment Positions and the Adjustment Positions as agreed upon by the Purchaser and the Sellers’ Representative and reflected in such revised Closing Statement will be deemed final. 

 

  
 -5- 

 (d) If the Sellers’ Representative and the Purchaser are unable to resolve such
disagreement within fifteen days after the delivery of the Notice of Disagreement, the Sellers’ Representative and the Purchaser will appoint a mutually acceptable independent accounting firm recognized as expert in international accounting
matters (the “Independent Accountant”) and will each submit to the Independent Accountant a written submission (each, a “Submission”) setting forth such Party’s calculation of each of the Adjustment Positions
and such Party’s positions on the issues in dispute. The engagement of the Independent Accountant will specify that (i) the Independent Accountant shall act as an expert and not an arbitrator, (ii) it will accept as accurate all
aspects of the calculation of the Adjustment Positions that have not been identified as disputed items, (iii) it will make its determination based solely on the applicable provisions of this Agreement (and not independent review), (iv) it will
base its determination solely on the Submissions (unless the Independent Accountant requests additional information from either the Sellers’ Representative or the Purchaser), and not on independent investigation, (v) the Independent
Accountant’s sole responsibility is to resolve the disputed items and provide the Parties with a calculation of the Adjustment Positions based on the Parties’ resolution of the non-disputed items and
the Independent Accountant’s resolution of the disputed items. The Sellers’ Representative and the Purchaser shall deliver to the Independent Accountant all information reasonably requested by the Independent Accountant to resolve such
disputed items and shall use commercially reasonable efforts to cause such determination to be made, and written notice thereof given to the Sellers’ Representative and the Purchaser, within thirty days after such information is provided to the
Independent Accountant. The determination by the Independent Accountant of the disputed items will be final, binding and conclusive upon the Parties hereto, absent manifest error. The scope of the Independent Accountant’s engagement (which will
not be an audit) will be limited to the resolution of the items identified as disputed items in the Submissions. The fees, costs and expenses of the Independent Accountant, if any, will be paid (A) fully by the Purchaser if the Adjustment
Positions as determined by the Independent Accountant are closer to the calculation of the Adjustment Positions as set forth in the Sellers’ Representative’s Submission than the calculation of the Adjustment Positions as set forth in the
Purchaser’s Submission (save as otherwise provided for in (C) hereinafter), (B) fully by the Sellers’ Representative (from the Sellers’ Representative Expense Fund or by contributions from the Sellers) if the Adjustment Positions
as determined by the Independent Accountant are closer to the calculation of the Adjustment Positions as set forth in the Purchaser’s Submission than the calculation of the Adjustment Positions as set forth in the Sellers’
Representative’s Submission (save as otherwise provided for in (C) hereinafter) and (C) 50% by the Purchaser and 50% by the Sellers’ Representative (from the Sellers’ Representative Expense Fund or by contributions from the
Sellers) if the Adjustment Positions as determined by the Independent Accountant are within USD 5,000 (five thousand US dollars) either side of the midway between the calculation of the Adjustment Positions as set forth in the Sellers’
Representative’s Submission and the calculation of the Adjustment Positions as set forth in the Purchaser’s Submission. Notwithstanding any provision herein to the contrary, in the event that the Adjustment Positions are determined
pursuant to this Section 2.4(d), then the Adjustment Positions shall be calculated by giving effect to the matters not in dispute as resolved by the Sellers’ Representative and the Purchaser and giving effect to the Independent
Accountant’s resolution of the matters in dispute, as reflected in a final report by the Independent Accountant, which shall be binding upon the Parties in the absence of manifest error.

 (e) For purposes of this Agreement, the adjustments to the Purchase Price contemplated by
this Section 2.4 (the “Purchase Price Adjustments”) shall be based on (i) the calculation of the Adjustment Positions as set forth in the Closing Statement in the event that either (A) the Sellers’
Representative notifies the Purchaser within the thirty day period described in Section 2.4(b) that the Sellers’ Representative agrees with the Purchaser’s calculation of the Adjustment Positions set forth in the Closing Statement or
(B) the Sellers’ Representative fails to provide any notification to the Purchaser with respect to such Closing Statement within such thirty day period, (ii) the calculation of the Adjustment Positions as agreed upon by the Purchaser
and the Sellers’ Representative if agreement is reached by the Purchaser and the Sellers’ Representative pursuant to Section 2.4(c) and (iii) the calculation of the Adjustment Positions identified in the last sentence of
Section 2.4(d) as being the operative calculation in the event that the Adjustment Positions are determined pursuant to Section 2.4(d). For purposes of this Agreement, (i) the terms “Final Cash” and “Final
Working Capital” shall mean the calculations of the Cash and Working Capital, respectively, which, pursuant to this Section 2.4(e), are the calculations upon which the Purchase Price Adjustments are to be based and (ii) the term
“Final Determination Date” shall mean the seventh day after the date on which the Final Cash, the Final Working Capital and the Final Deferred Revenues are determined hereunder. 

(f) If the Final Cash is more than USD 2,090,000 (such surplus, a “Cash Surplus”), then, by no later than the tenth Business
Day after the Final Determination Date, the Purchaser will pay to the Principal Sellers in cash an amount equal to 25% of the Cash Surplus, such payment to be made to the Sellers’ Solicitors Client Account and allocated among the Principal
Sellers by reference to their respective fractional interests following Closing as set forth in Exhibit A annexed hereto (the “Subsequent Fractional Interests”). 

(g) If the Final Working Capital is more than negative USD 7,070,888 (such surplus, a “Working Capital Surplus”), then, by no
later than the tenth Business Day after the Final Determination Date, the Purchaser will pay to the Principal Sellers in cash an amount equal to 25% of the Working Capital Surplus, such payment to be made to the Sellers’ Solicitors Client
Account and allocated among the Principal Sellers by reference to their respective Subsequent Fractional Interests. For avoidance of doubt, if the Final Working Capital is negative USD 7,070,887, that is deemed to be USD 1 more than negative USD
7,070,888. 
 (h) If the Final Cash is less than USD 1,710,000 (such deficit, a “Cash Deficit”), the Cash Deficit will
reduce the number of shares of Class A Stock issuable to the Operating Company Participating Sellers under Section 2.5(c)(iii) of the Operating Company Stock Sale and Purchase Agreement. 

(i) If the Final Working Capital is less than negative USD 8,642,197 (such deficit, a “Working Capital Deficit”), the Working
Capital Deficit will reduce the number of shares of Class A Stock issuable to the Operating Company Participating Sellers under Section 2.5(c)(iii) of the Operating Company Stock Sale and Purchase Agreement. For avoidance of doubt, if the
Final Working Capital is negative USD 8,642,198, that is deemed to be USD 1 less than negative USD 8,642,197.

 (c) the minute books, Tax Returns, accountant work papers, and Share transfer records of the

Period for a matter contemplated by this Article VI is longer than the statute of limitations that would otherwise have been applicable to such matter, then, by contract, the applicable statute of limitations with respect to such matter shall be
extended to the longer Survival Period contemplated hereby and (ii) if the applicable Survival Period for a matter contemplated by this Article VI is shorter than the statute of limitations that would otherwise have been applicable to such

Section 6.2(a) made after the expiration of the applicable Survival Period, provided that this sentence shall have no bearing on any such claim that is first made prior to the expiration of the applicable Survival Period. The Taxes, if any,
attributable to a Straddle Period shall be allocated (i) to the Operating Company Sellers for the period up to and including the close of business on the Closing Date, and (ii) to the Purchaser for the period subsequent to the Closing

of this Agreement by each of Samuel Manning, Peter Quarendon, Kevin Weekes and Benjamin Scurr with respect to themselves only (i.e. on a several basis) or with any breach of Sections 3.1(c), 3.3, 3.4, 3.8 or 3.12(w) of the Operating Company Stock

Agreement. The indemnification obligation for each Seller named under this Section 6.2(c) shall not apply to any claims for Damages unless and until such Damages exceed USD 20,000 (“Claims Threshold”), in which case such Seller
shall be required to pay or be liable for all such Damages from the first dollar of such Damages irrespective of the Claims Threshold. 
 (d)
Notwithstanding anything in this Agreement to the contrary, there shall be no duplication of recovery with respect to any matter for which indemnification is claimed pursuant to this Article VI and any matter for which indemnification is claimed
under the Operating Company Stock Sale and Purchase Agreement and any of the ancillary agreements delivered hereunder or thereunder. 
 (e)
Effective upon consummation of the Closing, the Purchaser shall indemnify and hold harmless the Sellers and any Person claiming by or through any of them, against and in respect of all Damages arising out of, resulting from or incurred in connection
with any breach of any warranty made by the Purchaser in this Agreement. 
 Section 6.3 Procedures for Claims. The following
provisions shall apply with respect to any indemnification claims made by the Purchaser against Samuel Manning pursuant to this Article VI and any claims made by the Sellers against the Purchaser pursuant to this Article VI (it being understood that
any claims made by the Purchaser against the Operating Company Sellers with respect to the matters set forth in Section 6.2(a) shall be governed by the procedures set forth in Section 6.3 of the Operating Company Stock Sale and Purchase
Agreement): 
 (a) In the case of any claim for indemnification arising from a claim of a third party (a “Third Party
Claim”), an Indemnified Party shall give prompt written notice, following such Indemnified Party’s receipt of such claim or demand, to the Indemnifying Party of any claim or demand of which such Indemnified Party has knowledge and as
to which it may request indemnification hereunder (a “Third Party Claim Notice”); provided, however, that failure to give such notice will not affect such Indemnified Party’s rights furnished hereunder unless, and
then solely to the extent that, the rights of the Parties from whom indemnity is sought are materially prejudiced as a result of such failure. The Indemnifying Party shall have the right to defend and to direct the defense against any such claim or
demand, in its name or in the name of the Indemnified Party, as the case may be, at the expense of the Indemnifying Party, and with counsel selected by the Indemnifying Party that is acceptable to the Indemnified Party (such acceptance not to be
unreasonably withheld, conditioned or delayed) unless (i) such claim or demand seeks an order, injunction or other equitable relief against the Indemnified Party, (ii) upon assumption of the defense, the Indemnifying Party fails to
acknowledge in writing to the Indemnified Party its indemnity obligations with respect to the full amount of Damages from such Third Party Claim without deduction, set-off or counterclaim hereunder (except for
the express limitations set forth in this Agreement) and its obligations to hold harmless the Indemnified Parties therefrom or (iii) the Indemnified Party shall have reasonably concluded that (x) there is a conflict of interest between the
Indemnified Party and the Indemnifying Party in the conduct of the defense of such 

  
 -37- 

 
claim or demand, (y) the Indemnified Party has one or more defenses not available to the Indemnifying Party or (z) if the Indemnified Party is a Purchaser Indemnified Party, the
underlying matter is a criminal matter, is a matter that reasonably could be expected to impact the business reputation of the Parent or is a matter that reasonably could, if the Third Party Claim is sustained, be expected to adversely impact
(I) any Tax position with respect to any Tax period (or portion thereof) beginning after the Closing Date or (II) the Intellectual Property, in each case, of the Company Group, of the Purchaser or of any other Affiliate of the Purchaser.
Notwithstanding anything in this Agreement to the contrary, the Indemnified Party shall, at the expense of the Indemnifying Party, cooperate with the Indemnifying Party, and keep the Indemnifying Party fully informed, in the defense of such claim or
demand. The Indemnified Party shall have the right to participate in the defense of any claim or demand with counsel employed at its own expense; provided, however, that, in the case of any claim or demand described in clause (i) or (ii)
of the second preceding sentence or as to which the Indemnifying Party shall not in fact have employed counsel that is acceptable to the Indemnified Party (such acceptance not to be unreasonably withheld, conditioned or delayed) to assume the
defense of such claim or demand, the reasonable fees and disbursements of the Indemnified Party’s counsel shall be at the expense of the Indemnifying Party, except as otherwise provided in Section 2.5(c)(iv)(B). The Indemnifying Party
shall have no indemnification obligations with respect to any such claim or demand which shall be settled by the Indemnified Party without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld,
conditioned or delayed. The Indemnifying Party shall not settle any such claim without the prior written consent of the Indemnified Party, unless (A) such settlement is accompanied by a document releasing the Indemnified Party from all
liability with respect to the matter in controversy, (B) such settlement shall not limit, damage or interfere with the continuing operation of the Business in any respect and (C) if the Indemnified Party is a Purchaser Indemnified Party,
such settlement shall not involve a criminal matter, a matter that reasonably could be expected to impact the business reputation of the Purchaser, Parent or any of their Subsidiaries or a matter that reasonably could be expected to adversely impact
the Intellectual Property of the Company Group, of the Purchaser or of any Affiliate of the Purchaser. For purposes of determining whether notice has been provided hereunder within an applicable Survival Period, notice shall be deemed to have been
given on the date that the Third Party Claim Notice is deemed received pursuant to Section 7.1. 
 (b) In the event that an Indemnified
Party determines that it has a claim for Damages against an Indemnifying Party hereunder (other than as a result of a Third Party Claim) (an “Interparty Claim”), the Indemnified Party shall give prompt written notice thereof to the
Indemnifying Party, specifying the amount of such claim, the section of this Agreement under which such claim arises and any other relevant facts and circumstances relating thereto (an “Interparty Claim Notice”); provided,
however, that failure to give such notice promptly will not affect such Indemnified Party’s rights furnished hereunder unless, and then solely to the extent that, the rights of the Parties from whom indemnity is sought are materially
prejudiced as a result of such failure. The Indemnified Party shall provide the Indemnifying Party with reasonable access to its books and records for the purpose of allowing the Indemnifying Party a reasonable opportunity to verify any such claim
for Damages. The Indemnified Party and the Indemnifying Party shall negotiate in good faith for a thirty day period (beginning on the date the Indemnified Party provides an Interparty Claim Notice hereunder) regarding the resolution of any disputed
claims for Damages. If no resolution is reached with regard to such disputed Interparty Claim between the Indemnifying Party and the Indemnified Party within such thirty day period, the Indemnified Party shall be entitled to seek appropriate
remedies in accordance with the terms hereof. For purposes of determining whether notice has been provided hereunder within an applicable Survival Period, notice shall be deemed to have been given on the date that the Interparty Claim Notice is
deemed received pursuant to Section 7.1. 

  
 -38- 

 (c) Promptly (and in any event within ten Business Days) following a final determination of
the amount of any Damages claimed by the Indemnified Party by either (i) a determination of an arbitrator pursuant to Section 7.3(d)(iii) or (ii) the mutual agreement by the Indemnified Party and Indemnifying Party (in either such
case, a “Final Damages Determination”), the Person required to pay such Damages shall pay such Damages by wire transfer to the address provided by the Person entitled to receive such Damages.

incident to this Agreement and the transactions contemplated hereby and the Sellers shall pay all expenses of the Sellers’ Representative and each entity in the Company Group relating hereto. 

Section 7.3 Payments. 

(a) Cash payments to be made to the Sellers under this Agreement, including any payment by the Sellers’ Representative from the
Sellers’ Representative Expense Fund should the Sellers’ Representative determine that the Sellers’ Representative no longer requires any of the money held in the Sellers’ Representative Expense Fund, will be made
by electronic transfer of immediately available funds to the Sellers’ Solicitors Client Account or to any other single client account in the United Kingdom of a reputable law firm of which the Sellers’ Representative gives the Purchaser at
least three business days’ notice from time to time. 
 (b) Payment of any sum to the Sellers’ Solicitors Client Account or
otherwise in accordance with Section 7.3(a) will discharge the obligations of the Purchaser to pay the sum in question and the Purchaser is not concerned to see the application of the monies so paid. 

(c) Payments to be made to the Purchaser under this Agreement will be made in US dollars calculated at the exchange rate quoted by the Bank of
England for the conversion of pounds into US dollars at midday on the day before the due date for payment, by electronic transfer of immediately available fund to an account of the Purchaser of which the Purchaser gives at least three business

 -40- 

 (d) If 

(i) any deduction of or withholding is required by law to be made from any sum payable by any Seller to the Purchaser under this Agreement,
the Seller shall pay such increased sum as will, after the deduction or withholding has been made, leave the Purchaser with the same amount as it would have been entitled to receive in the absence of such requirement to make a deduction or
withholding; and 
 (ii) any sum paid or payable to the Purchaser under this Agreement (“Original Sum”) is or will be
chargeable to Tax, the Sellers shall pay on demand to the Purchaser such additional sum as ensures that, after payment of the Tax, the Purchaser is left with an amount equal to the Original Sum, and for these purposes a sum shall be regarded as
chargeable to Tax in circumstances where it would have been chargeable to Tax but for some relief available to the Purchaser; 
 (iii) save
that if the Sellers make an increased payment pursuant to Section 7.3(a) above in respect of which the Purchaser receives or is granted any credit against, relief for, repayment of, any Tax payable by the Purchaser, which credit, relief, or
repayment the Purchaser would not otherwise have received or been granted, the Purchaser shall reimburse the Sellers such amount as leaves the Purchaser in no worse position than it would have been in had there been no such deduction or withholding.
The Purchaser shall notify the Sellers’ Representative of such credit, relief, or repayment and shall pay the Sellers in accordance with this Section 7.3 promptly after receiving or being granted the credit, relief or repayment in
question. 
 Section 7.4 Governing Law. 

(a) This Agreement, and all matters arising directly or indirectly from this Agreement, shall be governed by, and construed and interpreted in
accordance with, the Laws of England and Wales, without giving effect to the conflict of law provisions thereof. Except as otherwise provided in Section 2.4(d) and Section 7.15 (which shall govern in the event of any inconsistency with
this Section 7.4) or elsewhere in this Agreement, any unresolved controversy or claim arising out of or relating to this Agreement shall be submitted to arbitration pursuant to this Section 7.4. The Parties shall use their commercially
reasonable efforts to seek to settle amicably any dispute, controversy or claim arising out of or in connection with this Agreement, the transactions contemplated hereby or the breach, termination or validity hereof (a “Dispute”).
Before referring any such Dispute to arbitration, a Party must notify the other Parties of its wish to settle amicably the Dispute. Such notice (the “Dispute Notice”) shall include a written statement of the dispute and copies of
any documents related thereto. Each Party shall appoint one representative to negotiate on their behalf to attempt to reach an amicable settlement. Parent shall be deemed to be a “Party” for purposes of Section 7.4. 

(b) Failing an amicable settlement within two months of the receipt of the Dispute Notice, the Dispute shall be finally settled by arbitration
under the Rules of Arbitration of the International Chamber of Commerce then in effect (the “Rules”), except as modified herein. The arbitration shall be held in London (UK). 

(c) In an arbitration the following provisions shall apply: 

  
 -41- 

 (i) This agreement to arbitrate shall be specifically enforceable. The arbitrator, and not
a court, shall also be authorized to determine whether this agreement to arbitrate applies to any claim, discrepancy or dispute sought to be resolved hereunder. 

(ii) There shall be one arbitrator, selected in accordance with the Rules. 

(iii) The arbitrator shall be skilled in the field of intellectual property law, applicable governing law and the other legal and business
aspects of the subject matter of this Term Sheet or the Transaction Documents, as applicable, and also shall have served as an arbitrator at least three times prior to such arbitrator’s service as an arbitrator in this arbitration. 

(iv) Barring extraordinary circumstances, the arbitrator shall render an award within four months from the date on which the arbitrator is
selected. The arbitrator may extend this time limit in the interests of justice. Failure to adhere to this time limit shall not constitute a basis for challenging the award. 

(v) The parties shall be entitled to discovery in the arbitration except that any party shall be entitled to request no more than 1,000 pages
of documents and to take no more than three depositions not to exceed four hours for each such deposition. Any party shall be entitled to depose any expert who will testify in the arbitration proceeding but shall pay the regular hourly rate of such
expert during such deposition. In addition to the foregoing, any party shall be entitled to take the deposition of a witness who will testify at the arbitration but who is unavailable to testify at the hearing to preserve such witness’
testimony for the arbitration hearing. 
 (vi) The parties shall exchange a copy of all exhibits for the arbitration hearing and shall
identify each witness who will testify at the arbitration, with a summary of the anticipated testimony of such witness ten days before the arbitration hearing. 

(vii) The arbitrator shall be authorized to award direct compensatory damages, but shall not be authorized (a) to award non-economic damages, (b) to award punitive damages other than to compensate the Purchaser for punitive damages claimed in a Third-Party Claim, (c) to award indirect, special, incidental or consequential
damages other than to compensate the Purchaser for indirect, special, incidental or consequential damages claimed in a Third-Party Claim or (d) to reform, modify or materially change the Transaction Documents, except as expressly authorized
herein or therein. The arbitrator shall be entitled to issue injunctive and other forms of equitable relief. 
 (viii) The parties hereto
hereby waive any rights of application or appeal to the fullest extent permitted by law in connection with any question of law arising in the course of the arbitration or with respect to any award made, except for actions to enforce an arbitral
award in any court of competent jurisdiction. 
 (ix) The arbitrator shall be required to make written findings of fact and conclusions of
law to support the arbitrator’s award. The award shall be final and binding upon the parties hereto, and shall be the sole and exclusive remedy among the parties hereto regarding any claims, counterclaims, issues, or accounting presented to the
arbitrator. Judgement upon any award may be entered in any court of competent jurisdiction. 

  
 -42- 

 (x) Judgement upon the award of the arbitrator may be entered in any court having
jurisdiction thereof or such court may be asked to confirm judicially the award and order its enforcement, as the case may be. 
 (xi) Each
of the parties hereto shall bear its own attorney’s fees, costs and expenses and an equal share of the arbitrator’s fees and administrative fees of the arbitration. The parties agree that failure or refusal of a party to pay its required
share of the deposits for arbitrator compensation or administrative charges shall constitute a waiver by that party to present evidence or cross-examine witnesses. In such event, the other parties shall be required to present evidence and legal
argument as the arbitrator may require for the making of an award. 
 (xii) Except as may be required by law, neither a Party nor its
representatives may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of all Parties. 

(xiii) This agreement to arbitrate shall be binding upon the successors and assigns of each party hereto and thereto. 

Section 7.5 Assignment; Successors and Assigns; Limited Third Party Rights. Except as otherwise provided herein, this Agreement
may not be assigned, and any attempted assignment shall be null and void. The Purchaser may assign any or all of its rights under this Agreement to any Affiliate of the Purchaser, provided that the Purchaser shall remain secondarily liable
for all obligations of the Purchaser hereunder. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective successors, permitted assigns and legal representatives. This Agreement shall be for the sole
benefit of the Parties and their respective successors, assigns and legal representatives and is not intended, nor shall be construed, to give any Person, other than the Parties hereto and their respective successors, assigns and legal
representatives, any legal or equitable right, remedy or claim hereunder; provided, however, that Article VI shall also be for the benefit of the Purchaser Indemnified Parties. 

Section 7.6 Counterparts; Facsimile. 

(a) This Agreement may be executed in one or more counterparts, by facsimile or otherwise. Each such counterpart shall be deemed an original
agreement, but all of which together shall constitute one and the same instrument. 
 (b) Transmission of an executed counterpart of this
Agreement (and not just a signature page) by email in PDF (JPEG or other agreed format) will take effect as the transmission of an executed “wet ink” counterpart of this Agreement. If this method of transmission is adopted, without
prejudice to the validity of the Agreement so made, each Party will on request provide the others with “wet ink” hardcopy originals of their counterpart. 

(c) No counterpart will be effective until each Party has delivered to the others at least one executed counterpart. 

Section 7.7 Headings. The headings in this Agreement are for reference purposes only and shall not in any way affect the meaning
or interpretation of this Agreement. 

  
 -43- 

 Section 7.8 Entire Agreement and Fraud. This Agreement, including the disclosure
schedules and Exhibits attached thereto or delivered herewith, the Operating Company Stock Sale and Purchase Agreement and any confidentiality agreement heretofore delivered in anticipation of the execution of this Agreement, constitutes the entire
agreement among the Parties with respect to the matters covered hereby and supersedes all previous written, oral or implied understandings among them with respect to such matters. Nothing in this Agreement shall limit or exclude the liability of any
Party for the fraud of that Party or arising out of the fraud of any of its directors, employees, officers, agents or advisers.

have any right to rely upon or enforce any term of this Agreement pursuant to the Contracts (Rights of Third Parties) Act 1999. The rights of the parties to terminate, rescind or vary this Agreement are not subject to the consent of any third party

of the parties to this Agreement that in doing so, it agrees to be bound by the terms of Section 7.3(d)(iii). 
 Section 7.11
Waiver. Any of the terms or conditions of this Agreement may be waived at any time by the Party or Parties entitled to the benefit thereof, but only by a writing signed by the Party or Parties waiving such terms or conditions. 

Section 7.12 Severability. The invalidity of any portion hereof shall not affect the validity, force or effect of the remaining
portions hereof. If it is ever held that any restriction hereunder is too broad to permit enforcement of such restriction to its fullest extent, such restriction shall be enforced to the maximum extent permitted by Law. 

Section 7.13 Schedules. All references herein to Schedules or the Sellers’ Disclosure Schedule refer to the disclosure
schedules delivered by the Sellers to the Purchaser contemporaneous with the execution of this Agreement.

 Section 7.15 Sellers’ Representative. 

(a) Authorization of the Sellers’ Representative. Each Seller irrevocably appoints, authorizes and empowers the Sellers’

which such Seller is a party, including, without limitation, (i) the full power and authority on such Seller’s behalf to perform the activities on behalf of the Seller contemplated by this Agreement, (ii) negotiating the resolution
and/or final settlement and release of any monetary or non-monetary issues, disputes, claims (including claims brought by third parties), proceedings and/or litigation arising under this Agreement (including
without limitation Articles II and VI of this Agreement) or any other Seller Document, (iv) acting on behalf of such Seller in any litigation, arbitration or other judicial or administrative proceeding involving this Agreement (including
without limitation Articles II and VI of this Agreement) or any other Seller Document, (v) executing all such documents as the Sellers’ Representative shall deem necessary or appropriate in connection with the transactions contemplated by
this Agreement (including without limitation Articles II and VI of this Agreement) or any other Seller Document, including all amendments, waivers, ancillary agreements, stock powers, certificates and documents that the Sellers’ Representative
deems necessary or appropriate in connection with the consummation of such transactions, (vi) doing or refraining from doing any further act or deed in the name of and on behalf of such Seller that the Sellers’ Representative deems
necessary or appropriate in its sole discretion relating to the subject matter of this Agreement (including without limitation Articles II and VI of this Agreement) or any other Seller Document, as fully and completely as such Seller could do
if personally present, and (vii) receiving service of process in connection with any claims under this Agreement (including without limitation Articles II and VI of this Agreement) or any other Seller Document, in the name of and on behalf of
such Seller. Each Seller agrees that such agency and proxy are coupled with an interest, are therefore irrevocable without the consent of the Sellers’ Representative and shall survive the death, incapacity, bankruptcy, dissolution or
liquidation (in each case, if applicable) of each Seller. All decisions and actions by the Sellers’ Representative pursuant to, or permitted by, this Agreement or related thereto shall be binding upon each Seller, and each Seller shall have no
right to object, dissent, protest or otherwise contest the same. For the avoidance of doubt, (i) any action that may be taken by any Seller pursuant to Article VI, either as an Indemnifying Party or an Indemnified Party, shall be taken solely
by the Sellers’ Representative, (ii) any notice to be given to any Seller pursuant to Article II or Article VI shall be sufficient if given to the Sellers’ Representative and (iii) any agreement reached by the Purchaser or Parent
with the Sellers’ Representative under Article II or Article VI shall be binding upon all the Sellers, it being understood that for all purposes, the Sellers’ Representative shall act on behalf of all of the Sellers with respect to Article
II and Article VI. 
 (b) Death or incapacity of the Sellers’ Representative. In the event of the Sellers’
Representative’s death or incapacity, the Sellers shall promptly appoint a new Sellers’ Representative by agreement of all of the Sellers, or failing agreement within one week, Sellers holding prior to Closing a majority of the initial
fractional interests listed in the column headed “Fractional Interests” in Exhibit A annexed hereto (“Fractional Interests”) shall make such appointment, and shall send notice of such appointment to the Purchaser. 

Section 7.16 Specific Performance. The Sellers acknowledge and agree that the breach of this Agreement would cause irreparable damage
to the Purchaser and that the Purchaser will not have an adequate remedy at law. Therefore, the obligations of the Sellers under this Agreement, including the Sellers’ obligation to sell the Company Shares to the Purchaser, shall be enforceable
by a decree of specific performance issued by any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith. Such remedies shall, however, be cumulative and not exclusive and shall be
in addition to any other remedies which any Party may have under this Agreement or otherwise. 

  
 -45- 

 Section 7.17 Parent Guarantee. Parent hereby agrees to be jointly and severally
liable for the prompt and complete performance of the Purchaser’s payment obligations under this Agreement, but subject to the same limitations as those on the Purchaser’s obligations hereunder. The Parent’s obligations are
unconditional irrespective of any circumstances which might otherwise constitute, by operation of law, a discharge of a guarantor or surety and it shall not be necessary for the Sellers to institute or exhaust any remedies or causes of action
against the Purchaser or any other Person as a condition to the obligations of Parent hereunder. Except as provided in this Agreement, Parent hereby irrevocably waives any right to receive a formal notification or to request that any other
formalities or protest be accomplished in connection with its obligations hereunder. 
 Section 7.18 Parent hereby irrevocably
appoints the Purchaser as its agent to accept service of process in England and Wales in any claim arising out of this Agreement, service upon which shall be deemed completed whether or not forwarded to or received by Parent.
