On March 3, 2014, the Remuneration Committee (the “Committee”) of the Board of Directors of Oxford Immunotec Global PLC (the “Company”) made option and restricted share awards, approved bonuses, and adjusted the salaries of the Company’s named executive officers. These changes are described in the following table.

In connection with compensation decisions reflected above, the Committee adopted forms of restricted share award certificates under the Oxford Immunotec Global PLC 2013 Share Incentive Plan for employees and officers resident in different countries. Dr. Wrighton-Smith’s restricted share award was made on the form of the certificate for officers resident in the United Kingdom. Messrs. Schroeder’s and Altieri’s restricted share awards were made on the form of certificate for officers resident in the United States. These new forms of restricted share award certificates are filed as exhibits to this Current Report on Form 8-K.

The Committee previously adopted forms of stock option agreements for employees and officers resident in different countries under the Oxford Immunotec Global PLC 2013 Share Incentive Plan. Dr. Wrighton-Smith received compensatory stock option, or CSOP, awards to the maximum allowable permitted under U.K. rules applicable to such awards and the balance of his options were unapproved options granted on the form of agreement for unapproved options for officers resident in the United Kingdom. The form of CSOP award certificate is filed as an exhibit to this Current Report on Form 8-K. The form of unapproved option agreement for officers resident in the United Kingdom is also filed as an exhibit to this Current Report on Form 8-K. Messrs.

Both types of options were made on the form for stock options for officers resident in the United States. This form of option agreement is filed as an exhibit to this Current Report on Form 8-K.

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
