and (Y) the number of Ordinary Shares available to be, and actually, transferred from Genius to such Investor; and 
 (ii) an
additional number of Ordinary Shares (or Series A Shares, if the adjustment takes place prior to the initial public offering of the Company’s securities) so that each Investor’s post-adjustment shareholding percentage of the Company’s
outstanding voting securities is not diluted by the Company’s issuance of Ordinary Shares (or Series A Shares, if the adjustment takes place prior to the initial public offering of the Company’s securities) pursuant to this
Section 1.04(e); 
 (f) Notwithstanding anything contrary in the foregoing, the number of additional Ordinary Shares to be so
transferred or issued to the Investors to effect the adjustment under this Section 1.04 shall be reduced so that the total Adjusted Investor Shareholding Percentage of the Investors (excluding the TB Ordinary Shares), would not exceed, in the
aggregate, 10% of the total issued and outstanding Ordinary Shares of the Company, as calculated on a fully-diluted basis; provided that if as a result of the adjustment under this Sections 1.04, the total Adjusted Investor
Shareholding Percentage of the Investors (excluding the TB Ordinary Shares) would exceed, in the aggregate, 10% of the total issued and outstanding Ordinary Snares of the Company, as calculated on a fully-diluted basis, each Investor shall have the
option to first require the Company to redeem all its Series A Shares and all Ordinary Shares issued upon conversion of any Series A Shares owned by such Investor at an amount equal to 150% of the Purchase Price paid by such Investor under this

“Investor”) under that certain share purchase agreement dated August 29, 2007 (the “Share Purchase Agreement”), the Investor shall be entitled to the following contractual management rights, in addition to any
rights to non-public financial information, inspection rights, and other rights specifically provided to the Investor under the Transaction Documents or provided to all investors in the current financing: 
 1. The Investor shall be entitled to consult with and advise the management of the Company on significant business issues, including management’s
proposed annual operating plans, and management will meet with the Investor at any time during regular working hours during each year at the Company’s facilities at mutually agreeable times for such consultation and advice and to review
progress in achieving said plans on reasonable prior notice to the Company. 
 2. The Investor may examine the books and records of the
Company and inspect its facilities and may request information at reasonable times and intervals concerning the general status of the Company’s financial condition and operations, provided that access to highly confidential proprietary
information and facilities need not be provided. 
 3. If the Investor is not represented on the Company’s Board, the Company shall
invite a representative of such Investor to attend all meetings of its Board, in a non-voting observer capacity and, in this respect, shall give such representative copies of all notices, minutes, consents and other’ material that the Company

excluded from access to any material or meeting or portion thereof if the Company believes, upon advice of counsel, that such exclusion is reasonably
necessary to preserve the attorney-client privilege, to protect highly confidential proprietary information, or for other similar reasons. Upon reasonable notice and at a scheduled meeting of the Board or such other time, if any, as the Board may
determine in its sole discretion, such representative may address the Board with respect to the Investor’s concerns regarding significant business issues facing the Company. 
 4. The Investor agrees to use the same degree of care as the Investor uses to protect its own confidential information to keep confidential any

foregoing persons, a “Permitted Disclosee”) or legal counsel, accountants or representatives for the Investor or a Permitted Disclosee. Notwithstanding the foregoing, nothing contained herein shall prevent the Investor or any
Permitted Disclosee from (i) entering into any business, entering into any agreement with a third party or investigating in or engaging in investment discussions with any other company (whether or not competitive with the Company), provided
that the Investor or Permitted Disclosee does not, except as permitted in accordance with this paragraph, disclose any confidential information of the Company in connection with such activities, or (ii) making any disclosures required by law,
rule, regulation or court or other governmental order, provided that the Company is given reasonable advance notice of such required disclosure, to the extent reasonably practicable, so that it can take steps to mitigate such disclosure. 

The rights described herein shall terminate and be of no further force or effect upon (a) the consummation of the sale of the Company’s
securities pursuant to a registration statement filed by the Company under the Securities Act of 1933, as amended, in connection with a firm-commitment underwritten offering of its securities to the public or (b) the consummation of a merger or
consolidation of the Company that is effected (i) for independent business reasons unrelated to extinguishing such rights and (ii) for purposes other than (A) the reincorporation of the Company in a different jurisdiction or

determine in its sole discretion, such representative may address the Board with respect to the Investor’s concerns regarding significant business issues facing the Company. 

 4. The Investor agrees to use the same degree of care as the Investor uses to protect its own
confidential information to keep confidential any information furnished to it by the Company pursuant to the provisions set forth in this letter which the Company identifies as being proprietary or confidential except such information that
(i) was in the public domain prior to the time it was furnished to the Investor, (ii) is or becomes (through no willful improper action or inaction by the Investor) generally available to the public, (iii) was in its possession or
known by the Investor without restriction prior to receipt from the Company, (iv) was rightfully disclosed to the Investor by a third party without restriction or (v) was independently developed without any use of the Company’s
confidential information. Notwithstanding the foregoing, the Investor may disclose such proprietary or confidential information to any current or prospective partner, limited partner, general partner or management company of the Investor (or any
employee or representative of any of the foregoing) (each of the foregoing persons, a “Permitted Disclosee”) or legal counsel, accountants or representatives for the Investor or a Permitted Disclosee. Notwithstanding the foregoing,
nothing contained herein shall prevent the Investor or any Permitted Disclosee from (i) entering into any business, entering into any agreement with a third party or investigating in or engaging in investment discussions with any other company
(which is not competitive with the Company), provided that the Investor or Permitted Disclosee does not, except as permitted in accordance with this paragraph, disclose any confidential information of the Company in connection with such activities,
or (ii) making any disclosures required by law, rule, regulation or court or other governmental order, provided that the Company is given reasonable advance notice of such required disclosure, to the extent reasonably practicable, so that it
can take steps to mitigate such disclosure. 
 The rights described herein shall terminate and be of no further force or effect upon
(a) the consummation of the sale of the Company’s securities pursuant to a registration statement filed by the Company under the Securities Act of 1933, as amended, in connection with a firm-commitment underwritten offering of its
securities to the public or (b) the consummation of a merger or consolidation of the Company that is effected (i) for independent business reasons unrelated to extinguishing such rights and (ii) for purposes other than (A) the
reincorporation of the Company in a different jurisdiction or (B) the formation of a holding company that will be owned exclusively by the Company’s shareholders and will hold all of the outstanding shares of capital stock of the
Company’s successor. The confidentiality provisions hereof will survive any such termination for two years. 
 Capitalized terms not
otherwise defined herein shall have the same meanings as given in the Share Purchase Agreement.
