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 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

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.

 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 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 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) 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 Operating Company Sellers in respect of warranties referenced in Section 3.12 or elsewhere in this 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 (b) Taxes arising out of or in connection
with any asset sales or other transfers, reorganizations, or recapitalizations involving the Company Group 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 

  
 -34- 












 
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 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(c) of the Operating Company Stock
Sale and Purchase Agreement, the Operating Company Participating 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; 

(ii) any and all Taxes (or the non-payment thereof) of the 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 are responsible, as provided in Section 5.5(b), or (y) arising from the transactions contemplated by this Agreement,
including, for the avoidance of doubt, any Transfer Taxes for which the Sellers are responsible, as provided in Section 5.5(b); 

(iii) any Long-Term Indebtedness of the Company Group as of the Closing Date that is not accurately reflected in the Closing Certificate; 

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

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

(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 

  
 -35- 












 (vii) any Investment Firm Closing Fees and Expenses that are not accurately reflected in
the 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 Operating Company Stock Sale and Purchase Agreement. 

The Purchaser Indemnified Parties shall not be entitled to recover Damages from the Operating Company 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 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
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 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 imposed on a periodic basis (including real property and ad valorem Taxes), the allocation between the Operating
Company 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.
Notwithstanding any provision herein to the contrary, the Purchaser’s sole recourse for claims against the Operating Company Sellers with respect to the matters set forth in this Section 6.2(a) shall be to bring a claim against the
Operating Company Sellers pursuant to Article VI of the Operating Company Stock Sale and Purchase Agreement to reduce the number of shares of Class A Stock issuable to the Operating Company Sellers pursuant to the Operating Company Stock Sale
and Purchase Agreement. 
 (b) Any Person providing indemnification pursuant to the provisions of Section 5.1 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 or this Section 6.2 is hereinafter referred to as an “Indemnified
Party.” 
 (c) Effective upon consummation of the Closing, Samuel Manning, Peter Quarendon, Kevin Weekes and Benjamin Scurr shall
each (on a several basis) 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 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 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
Sale and Purchase Agreement or the last sentence of Section 3.6 of the Operating Company Stock Sale and Purchase Agreement by each of Peter Quarendon, Kevin Weekes and Benjamin Scurr with respect to themselves only (i.e. on a several basis),
subject to each of Samuel Manning’s, Peter Quarendon’s, Kevin Weekes’s and Benjamin Scurr’s Liability Cap and the following provisions of this Section 6.2(c). Such Damages shall be payable within twenty Business Days after a


  
 -36- 












 
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 Samuel
Manning, Peter Quarendon, Kevin Weekes and Benjamin Scurr, the term “Liability Cap” means the aggregate cash consideration theretofore paid to each of Samuel Manning, Peter Quarendon, Kevin Weekes and Benjamin Scurr under this
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.

 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 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
days’ notice. 

  
 -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. 

Section 7.9 Amendment and Modification. This Agreement may be amended or modified only in a writing signed by the Party against
whom enforcement of such amendment or modification is sought. 
 Section 7.10 Third Party Rights. No third party shall
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
and no third party may enforce any term of this Agreement unless it has first (and as a pre-condition of commencing any legal proceedings in relation to such enforcement) confirmed by notice in writing to each
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 7.14 Set-off. The Purchaser shall be entitled to offset: 
 (a) any amount due from the Sellers to the
Purchaser under this Agreement against any obligation owed by the Purchaser to the Sellers pursuant to this Agreement; and 
 (b) any amount
due from any of the Operating Company Sellers under or pursuant to the Operating Company Stock Sale and Purchase Agreement (including any claims for breach of the Operating Company Stock Sale and Purchase Agreement) against any obligation owed by
the Purchaser to them under this Agreement. 

  
 -44- 












 Section 7.15 Sellers’ Representative.
