In consideration of the benefits of the Offering to each of the undersigned and its affiliates and subsidiaries and to induce the

Ordinary Shares and/or ADSs are listed. The foregoing undertaking shall be enforceable by any Holder or Holders of at least 10% of outstanding ADSs in the aggregate. 
 This Letter of Undertaking shall be governed by, and construed in accordance with, the laws of Jamaica. 
 Each of the undersigned hereby submits to the jurisdiction of the U.S. federal and New York state courts in the Borough of Manhattan in The City of New York (collectively, the “New York
