As used herein, the term “Relevant Security” means Ordinary Shares, Investor Warrants, any warrant to purchase Ordinary Shares or any other security of the Company or any other entity that is convertible into, or exercisable or exchangeable for, Ordinary Shares or any other equity or equity linked security of the Company, including any American Depositary Shares representing the foregoing, in each case owned beneficially or otherwise by the undersigned on the date of closing of the Public Offering or acquired by the undersigned during the Lock-Up Period; provided however, a Relevant Security does not include any Ordinary Shares, including American Depositary shares representing the foregoing that is acquired as a result of any equity award under any equity plan of the Company for the benefit of directors, officers or consultants.
