 THIS WARRANT (“WARRANT”) CERTIFIES THAT, for good and valuable consideration, the
receipt of which is hereby acknowledged, SQUARE 1 BANK or its assignee (“Holder”) is entitled to purchase the number of fully paid and nonassessable ordinary shares (the
“Shares”) of Oxford Immunotec Limited (the “Company”) at the initial exercise price per Share (the “Warrant Price”) all as set forth
above and as adjusted pursuant to Article 2 of this warrant, subject to the provisions and upon the terms and conditions set forth in this warrant. 

ARTICLE 1 
 EXERCISE

 1.1 Method of Exercise. Holder may exercise this warrant by delivering this warrant and a duly executed Notice of Exercise in
substantially the form attached as Appendix 1 to the registered office of the Company. Unless Holder is exercising the conversion right set forth in Section 1.2, Holder shall also deliver to the Company a check for the aggregate Warrant Price
for the Shares being purchased. 







 1.2 Conversion Right. In lieu of exercising this warrant as specified in Section 1.1,
Holder may from time to time convert this warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of the Shares or other securities otherwise issuable upon exercise of this warrant minus
the aggregate Warrant Price of such Shares by (b) the fair market value of one Share. 
 1.3 Intentionally Omitted. 

1.4 Intentionally Omitted. 

1.5 Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this warrant, and Company receives payment of
the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not so acquired. 

1.6 Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor. 
 1.7 Repurchase on Sale,
Merger, or Consolidation of the Company. 
  

	 	1.7.1.	“Acquisition.” For the purpose of this Warrant, “Acquisition” means (a) any sale, license, or other disposition of all or substantially all of the assets (including intellectual
property) of the Company, (b) any sale or disposition of all or substantially all of the capital stock of the Company, or (c) any reorganization, consolidation, merger or sale of the voting securities of the Company or any other
transaction or series of transactions where the holders of the Company’s securities before the transaction or series of transactions beneficially own less than 50% of the outstanding voting securities of the surviving entity after the
transaction or series of transactions. 

  

	 	1.7.2.	Deemed Exercise. If upon the closing of any Acquisition the Holder has not exercised this warrant in full, then Holder shall, at its option, by giving notice to the Company deem this warrant to have been
automatically converted pursuant to Section 1.2 and the Company shall procure that the Holder shall participate in the Acquisition on the same terms as other holders of the same class of securities of the Company. 


ARTICLE 2 
 ADJUSTMENTS
TO THE SHARES 
 2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on its ordinary shares payable in
ordinary shares, or other securities, or subdivides the outstanding 

  
 -2- 








 
ordinary shares into a greater number of ordinary shares, then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total number and kind of
securities to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend or subdivision occurred. 

2.2 Reclassification, Exchange or Substitution. Upon any reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall be entitled to receive, upon exercise or conversion of this Warrant, the number and kind of securities and property that Holder
would have received for the Shares if this Warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. Such an event shall include any automatic conversion of the outstanding or issuable securities of
the Company of the same class or series as the Shares to ordinary shares pursuant to the terms of the Company’s Certificate of Incorporation upon the closing of a registered public offering of the Company’s ordinary shares. The Company or
its successor shall promptly issue to Holder a new warrant for such new securities or other property. The new warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this
Article 2 including, without limitation, adjustments to the Warrant Price, the number of securities or property issuable upon exercise of the new warrant and expiration date. The provisions of this Section 2.2 shall similarly apply to
successive reclassifications, exchanges, substitutions, or other events. 
 2.3 Adjustments for Combinations, Etc. If the outstanding
Shares are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased. If the outstanding Shares are combined or consolidated, by reclassification or otherwise,
into a greater number of shares, the Warrant Price shall be proportionately decreased. 
 2.4 Certificate as to Adjustments. Upon
each adjustment of the Warrant Price, the Company at its expense shall promptly compute such adjustment, and furnish Holder with a certificate signed by its Chief Financial Officer setting forth such adjustment and the facts upon which such
adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant Price in effect upon the date thereof and the series of adjustments leading to such Warrant Price. 

2.5 Fractional Shares. No fractional Shares shall be issuable upon exercise of this Warrant and the number of Shares to be issued shall
be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the Warrant, the Company shall eliminate such fractional share interest by paying Holder the amount computed by multiplying the
fractional interest by the fair market value of a full Share. 
 2.6 Adjustments for Diluting Issuances. In the event of the issuance
(a “Diluting Issuance”) by the Company after the Issue Date of securities at a price per share less than the Warrant Price (the “Offer Price”), then the number of Shares subject to the Warrant shall be increased to that number of
Shares which can be purchased at the Offer Price out of the aggregate Warrant Price. Notice will be sent to the Holder detailing the adjusted number of Shares (fractional entitlements being ignored) and the new Warrant Price (being the Offer Price),


  
 -3- 








 
along with a new warrant certificate showing such adjusted number of Shares and Warrant Price. For the avoidance of doubt, Company’s issuance of options or shares arising upon exercise of
such options pursuant to the Company’s Amended and Restated 2008 Stock Incentive Plan shall not be a Diluting Issuance for purposes of this Section 2.6.
