Explanatory Note

This amendment is being filed to amend and supplement Item 5.02 of the Current Report on Form 8-K filed by Cott Corporation (the “Company”) on May 6, 2015, to disclose the material terms of Mr. Ausher’s Offer Letter to serve as the Company’s Chief Accounting Officer.

On May 5, 2015, the Company appointed Jason Ausher, 41, as the Company’s Chief Accounting Officer, effective May 15, 2015. In connection with his appointment, on May 20, 2015, the Company entered into an Offer Letter with Mr. Ausher setting out the terms of his employment.

Mr. Ausher will earn an annual base salary of $250,000 and is eligible to participate in the Company’s annual executive bonus plan with an annual target bonus equal to 50% of his base salary, and he has the opportunity to earn up to 200% of his base salary for achievement of goals in excess of the target goals, as approved by the Human Resources and Compensation Committee.

If Mr. Ausher’s employment is terminated by the Company without Cause or by Mr. Ausher for Good Reason (as such terms are defined in the Offer Letter), he would receive a cash payment equal to six months’ base salary.

Mr. Ausher is subject to standard confidentiality undertakings and has agreed to several restrictive covenants. He has agreed to a non-competition covenant that generally limits his ability to compete with the Company in any countries in which it conducts business. He has also agreed to non-solicitation and non-disparagement covenants. These limitations continue during the term of employment and for a period of six months following termination, regardless of the cause of the termination.

There is no arrangement or understanding between Mr. Ausher and any other person(s) pursuant to which he was selected as Chief Accounting Officer. Mr. Ausher does not have any family relationship with any director, executive officer, or person nominated or chosen by the Company to become a director or executive officer. Other than his employment relationship, Mr. Ausher does not have a direct or indirect material interest in any transaction in which the Company is a participant.
