	SCOPE OF YOUR EMPLOYMENT


	2.1
	During your Employment you will:


		(a)
	work on a full-time basis for AstraZeneca and devote all of your working time, attention and skill to the business of the Group (save for time spent on non-AstraZeneca Directorships with prior written consent of the Board);


		(b)
	diligently perform those duties, obey directions and exercise powers consistent with your position as may be assigned to you by the Chief Executive Officer of AstraZeneca (“CEO”) or the Board;

		(d)

	3.
	PLACE OF WORK


Your primary place of work will be AstraZeneca’s offices in Cambridge, but AstraZeneca may require you to travel and to work at any place on a temporary basis and you may also spend part of your working week at AstraZeneca’s offices in London.
	4.
	REMUNERATION


	4.1
	Your base salary will be paid at the rate of £850,000 per annum by equal monthly instalments in arrears by bank transfer.  Tax and any sums you owe to AstraZeneca may be deducted from your salary, as appropriate.  No sums you owe to AstraZeneca will be deducted from your salary without reasonable prior notice to you.  Your salary will be reviewed, but not necessarily increased, in February each year with any changes backdated to 1 January of that year.  No salary review will occur after either party has given notice to terminate your Employment.


	4.2
	During your Employment you will be entitled to participate in such discretionary performance-related bonus schemes and share incentive schemes as the Board may determine.  Details of any awards and participation conditions will be notified to you separately.

​



	4.3
	In the year in which your Employment terminates, any performance-related bonus will be determined at the discretion of the Board, taking into account Group and your performance and the period you have worked during that bonus year.


	4.4
	AstraZeneca operates a flexible benefits arrangement.  Your annual benefit funding is 11% of your base salary.  This includes AstraZeneca’s funding for your pension.  Contributions you elect to make to your pension will be deducted from your benefit funding.  The balance of your benefit funding can be used to purchase a range of benefits or taken in cash.  AstraZeneca will also provide a range of core AstraZeneca-funded benefits, such as income protection and private medical healthcare for you.   This means that AstraZeneca will cover the cost of these benefits and you don’t have to pay for them. Please note that private medical healthcare cover is taxable.


	5.
	EXPENSES


AstraZeneca will reimburse you for all expenses you reasonably incur in the proper performance of your duties in accordance with AstraZeneca’s expenses policy.
	6.
	HOLIDAYS


	6.1
	You will be entitled, in addition to all public holidays normally observed in England, to 22 working days' paid holiday in each holiday year (being the period from 1 July to 30 June).  You may take holiday at such times as are agreed with the CEO.


	6.2
	During the holiday years in which your Employment commences or terminates, your entitlement to holiday shall accrue on a pro rata basis for each completed calendar month of service during the relevant year.


	6.3
	If, on the termination of your Employment, you have exceeded your accrued holiday entitlement the excess, calculated on the basis that each day of paid holiday is equivalent to 1/260 of your base salary, may be deducted by AstraZeneca from any sums due to you.  If you have any unused holiday entitlement, AstraZeneca may pay you in lieu or require you to use it during your notice period.


	6.4
	Holiday entitlement for one holiday year cannot be taken in subsequent holiday years unless agreed by the Board.  If you do not take holiday in the appropriate holiday year you will lose it.


	7.
	SICKNESS BENEFITS


	7.1
	AstraZeneca will pay your salary and provide contractual benefits for up to 130 working days’ absence due to medically certified illness in any period of 12 calendar months or for the first 130 working days’ of absence in any one continuous period.


	7.2
	AstraZeneca can require you to undertake medical examinations with a doctor of AstraZeneca's choice.  AstraZeneca can receive a copy of any report produced in connection with all such examinations and to discuss the contents of the report with the doctor who produced it.


	8.
	PENSION


During your Employment you will be entitled to participate in the AstraZeneca Group Self Invested Personal Pension Plan (“GSIPP”) as it exists on the effective date of this Contract and any successor plans, subject to the applicable rules.
	9.
	DURATION OF YOUR EMPLOYMENT


	9.1
	Your continuous employment began on 13 November 2017 and will continue until terminated by either you or AstraZeneca by giving 12 months’ notice in writing to the other.


	9.2
	At any time during any period of notice given under clause 9.1 (whether given by AstraZeneca or by you), you may be placed on "garden leave" in which case the Group will not be under any obligation to provide work to you.  During garden leave AstraZeneca will have the right to assign you reduced or alternative duties, limit or terminate your access to Group IT systems, exclude you

	10.
	TERMINATION


	10.1
	Either party may terminate your Employment in accordance with clause 9.1, including in circumstances where you are absent due to ill health and would otherwise receive permanent health insurance benefits. You will be required to mitigate your loss if AstraZeneca terminates your Employment without requiring you to work for some or all of your notice period.


	10.2
	AstraZeneca may terminate your Employment at any time with immediate effect and pay a sum in lieu of notice in full and final settlement of any claims you may have against the Group equal to:

	the cost to AstraZeneca of funding any contractual benefit arrangement operated by AstraZeneca from time to time in respect of your Employment during the Relevant Period.


	10.3

	10.4
	If AstraZeneca believes that it may be entitled to terminate your Employment for Cause, it will be entitled to suspend you on full pay for so long as it considers appropriate.  If you are suspended in this way, AstraZeneca will still have the right to terminate your Employment on the same or another ground at a later date.


	10.5
	You will return all Confidential Information and AstraZeneca equipment at the request of AstraZeneca when your employment terminates or if you are placed on garden leave.  If requested by the Board, you will also resign from all offices, trusteeships and committee memberships held by you in the Group by virtue of your Employment and will transfer any qualifying shares held by you as nominee for the Group.


	11.
	DIRECTORS AND OFFICERS LIABILITY INSURANCE


The Group will maintain Directors’ and Officers’ liability insurance during your Employment to the fullest extent permitted by law in accordance with AstraZeneca’s policy.
