15	Termination by Notice

15.1

If either notice to terminate the Employment is given by the Executive according to Section 3.2 (iii) above, or if the Executive resigns without giving due notice and the Company does not accept his resignation or the Company has given notice in accordance with Section 3.2 (ii) above then the Company may require the Executive to comply with any and all of the provisions in this Section 15.1 for a maximum period of 12 months (the “Garden Leave Period”).

The Company may require that the Executive does not:

(i)

enter or attend the premises of the Company, or any Group Company; or

(ii)

contact or have any communication with any customer or client of the Company, or any Group Company in relation to the business of the Company, or any Group Company; or

(v)

remain or become involved in any aspect of the business of the Company, or any Group Company except as required by such companies.

15.1.2

The Company may require the Executive:

(i)

to comply with the provisions of Section 12; and

(ii)

to immediately resign from any directorship which he holds in the Company, and any Group Company or any other company where such directorship is held as a consequence or requirement of the Employment, unless he is required to perform duties to which any such directorship relates in which case he may retain such directorships while those duties are ongoing. The Executive hereby irrevocably appoints the Company to appoint an officer of GSK plc as his attorney to execute any instrument and do anything in his name and on his behalf to effect his resignation if he fails to do so in accordance with this Section 15.1.2(ii).

(i)

continue to be bound by the provisions of this Agreement and conduct himself with good faith towards the Company and not do anything that is harmful to the Company or any Group Company;

(ii)

remain available to perform any reasonable duty requested by the Company or any Group Company and to co-operate generally with the Company or any Group Company to ensure a smooth handover of his duties (provided that if the Executive should fail to make himself available for such work having been requested by the Company or any Group Company to attend he shall, notwithstanding any other provision of this Agreement forfeit his right to salary and contractual benefits in respect of such period of non-availability).

15.1.4

During the Garden Leave Period, the Executive will be entitled to receive his salary and benefits in accordance with the terms of this Agreement including any bonus payable in accordance with Section 5.2 but excluding any share entitlements under Section 5.2 above.

15.1.5

Where the Company gives notice to terminate the Employment in accordance with Section 3.2 (except where termination is effected pursuant to the terms of Section 14) above then notwithstanding the continuation of the Employment during any period after notice has been given, including any Garden Leave Period, within 30 days of the date such notice was given to the Executive, the Company shall pay to the Executive as a lump sum his full salary, bonus and 12 months pension contributions at the rate of eighteen per cent (18%) of the Executive’s full salary and bonus, in respect of the entire period of notice (except for any part of it attributable to the period falling after the Termination Date contemplated in Section 3.2(iv) and subject to deduction of tax and any other deductions required to be made) (the “Lump Sum”). For this purpose, full salary shall be the basic salary in effect at the date such notice is given to the Executive, and bonus shall be calculated on the basis of the Executive achieving 100 per cent of the target bonus at Bonus Level 1. For the avoidance of doubt, the payment by the Company to the Executive of the Lump Sum will extinguish any and all liability imposed on the Company under this Agreement to make any further payment to the Executive in respect of salary and bonus under this Agreement during any period after notice has been given, including, any Garden Leave Period.

However, in the event that the Executive obtains an offer of future alternative employment with another employer, or otherwise wishes to take up alternative business activities, and he can satisfy the GSK Board that such employment/activities are not in breach of Section 16, the Company will waive the balance of any unexpired notice period or the Garden Leave Period so as to enable the Executive to take up such alternative employment/activities; whereupon, subject to Section 12.3 above, the Company’s obligations to the Executive under this Section 15.1 shall cease with effect from the agreed revised Termination Date.

- 10 -

15.1.8

The Company and the Executive agree that if the Company shall fully perform, when due, all its obligations under this Section 15, such performance shall be in full and final settlement of all and any claims or rights of action which the Executive might have against the Company, or any Group Company arising out of this Agreement or its termination or otherwise howsoever relating to the Employment.

15.1.9

A removal by the Company of the Executive from his current position which results in a demotion to a position with less responsibility than his current position, or a change in reporting relationships which results in the Executive no longer reporting directly to the GSK Board, or any successor board, will be deemed to be a termination by the Company on notice pursuant to Section 15 of this Agreement.

16	Restrictions during and after Termination of Employment

16.1

In this Section:

“Restricted Business” means the businesses of the Company or any Group Company at the Termination Date (or if earlier the start of any Garden Leave Period ending on the Termination Date) with which the Executive was involved to a material extent during the last 12 months of the Employment.

“Restricted Period” means any period during which the Executive is employed by the Company (including for the avoidance of doubt, any Garden Leave Period) and the period of 12 months, less any Garden Leave Period imposed by the Company under Section 15 and less any period of notice worked by the Executive during the notice period set out in Section 3, commencing on the Termination Date.

16.2

The Executive is likely to obtain trade secrets and confidential information and personal knowledge of and influence over customers, clients and employees of the Company, GSK plc and its Group Companies during the course of the Employment. To protect these interests, the Executive agrees with the Company and GSK plc that the Executive will be bound by the following covenants:

16.2.1

During the Restricted Period he will not be engaged in (except as the holder, directly or indirectly, of less than 5 per cent of the shares) any business which is or is about to be in competition with the Restricted Business.

16.2.2

During the Restricted Period the Executive will not, canvass or solicit in competition with the Company, or any Group Company the custom of any person who was during the last 12 months of the Employment a customer, or client of, or in the habit of dealing with, the Company, or (as the case may be) any Group Company and in respect of which the Executive had access to confidential information or with whose custom or business the Executive is or was personally concerned, during that 12 month period with a view to providing goods or services to that person in competition with any Restricted Business.

16.2.3

During the Restricted Period he will not, in the course of any business concern which is in competition with the Restricted Business provide goods or services to or otherwise have any dealings with any person who was during the last 12 months of the Employment a customer, or client of, or in the habit of dealing with the Company, or any Group Company, and in respect of which the Executive had access to confidential information or with whose custom or business the Executive is or was personally concerned during that 12 month period.

- 11 -

16.2.4

During the Restricted Period he will not, interfere or endeavour to interfere with the continuance of the provision of goods or services to the Company, or any Group Company, by any supplier which was a supplier of goods or services to the Company, or any Group Company during the last 12 months of the Employment and with whom the Executive dealt to a material extent during that period.

16.2.5

During the Restricted Period he will not entice or try to entice away from the Company or any Group Company any person who is still employed by the Company or a Group Company during the Restricted Period and is a senior employee, director or full time senior consultant of such a company and with whom he worked closely in the last six months of the Employment.

16.3

Each of the obligations imposed on the Executive by this Section 16 extend to him acting not only on his own account but also on behalf of any other firm, company or other person and shall apply whether he acts directly or indirectly.

16.4

Following the Termination Date, the Executive will not represent himself as being in any way connected with the businesses of the Company, GSK plc or of any other Group Company (except to the extent agreed in writing by such a company).

16.5

Any benefit given or deemed to be given by the Executive to any Group Company under the terms of Section 16 is received and held on trust by the Company for the relevant Group Company. The Executive will enter into appropriate restrictive covenants directly with other Group Companies if asked to do so by the Company or GSK plc.

17	Reasonableness of Restrictions

17.1

Each of the obligations on the Executive contained in Section 16 constitutes a separate and independent restriction on the Executive notwithstanding that they may be contained in the same Section, paragraph or sentence.

17.2

Should the restrictions contained in Section 16 be found to be void but would be valid if some part thereof were deleted or the period or radius of application reduced, then such restriction shall apply with such modification as may be necessary to make it valid and effective. In particular, the Executive agrees that the restrictions are reasonable and necessary for the protection of the Company and the Group Companies.

17.3

If the Executive shall, during the Restricted Period, receive from any person, firm or company, an offer to provide services in any capacity whatsoever, or to enter into employment where acceptance of such offer, or the taking of such employment, might render him in breach of the provisions of this Agreement, he shall promptly advise the offeror of the existence of the restrictions set forth in Section 16 of this Agreement.

17.4

The Executive acknowledges that the Company may have no adequate remedy at law and would be irreparably harmed if the Executive breaches or threatens to breach the provisions of Section 16 above and, therefore, agrees that the Company shall be entitled to injunctive relief to prevent any breach or threatened breach of Section 16 above, and to specific performance of the terms of each such Section in addition to any other legal or equitable remedy it may have. The Executive further agrees that he shall not, in any equity proceedings involving him relating to the enforcement of Section 16 above raise the defence that the Company has an adequate remedy at law. Nothing in this Agreement shall be construed as prohibiting the Company from pursuing any other remedies at law or in equity that it may have.

- 12 -

18	Severability

In the event that any provision or portion of this Agreement shall be determined to be invalid or unenforceable for any reason, the remaining provisions or portions of this Agreement shall be unaffected thereby and shall remain in full force and effect to the fullest extent permitted by law.

19	Successors and Assigns

This Agreement shall be binding upon and inure to the benefit of the Company or any corporation or other entity to which the Company may transfer all or substantially all of its assets and business and to which the Company may assign this Agreement, in which case “Company”, as used in this Agreement, shall mean such corporation or other entity. The foregoing shall not relieve the Company of any of its obligations under Section 15 of this Agreement. The rights of the Executive shall inure to the benefit of his heirs, executors, administrators and other personal representatives.

19.2

The Executive may not assign this Agreement or any part of it, or any rights thereunder or delegate any duties to be performed by him under it to anyone else.

Appendix 3: GSK US Localisation Policy

The US Localisation Policy is an extract from GSK Global Assignment Policy which was effective in March 2006.

Philosophy

One of the consequences of undertaking a Global Assignment is that there may be a desire by both the employee and the Host Company for the employee to remain in the Host country. In these circumstances the Localisation policy will apply.

Therefore at the end of an assignment it may be mutually agreed that the Global Assignee will permanently localise to the assignment location. This means the assignment location will become the new Home location on a permanent basis.

Where localisation occurs the individual will become an employee of the new country business and will sever all employment links with their original Home country business.

Objective

The objective of localisation is to integrate a Global Assignee into the new Home location's Total Reward system, recognising that a period of transition may be necessary before the Global Assignee achieves equity with peers in the new Home location.

Localisation Principles

If a localisation is to proceed, the following will occur:

Global Assignment Terms and Conditions cease on localisation

Old Home country Terms and Conditions cease on localisation

New Home country Terms and Conditions will be adopted on localisation

At the end of the any transition period (see Section 13.6.6/7 Transition Allowance) the localised employee will be on an equitable basis with their local peers and other localised/transitioned employees.

Scope

Global Assignments do not exceed three (3) years, unless the CEO and appropriate CET member agree a maximum extension of one (1) year.

Global Assignees will be offered localisation for one (1) or more of the reasons below:

The Host Company wishes to retain and utilise the Global Assignee's skills longer than the maximum Global Assignment duration. The Global Assignee agrees to be localised and to adopt the new Home location Terms and Conditions.

There is no alternative role available to the Global Assignee on completion of the assignment; however the Host Company wishes to retain and utilise the Global Assignee's skills. The Global Assignee agrees to be localised and to adopt the new Home location Terms and Conditions.

- 18 -

The Global Assignee wishes to be localised and to adopt the new Home location Terms and Conditions. The Host Company wishes to retain and utilise the Global Assignee's skills and agree to support the localisation.

- 19 -

Compensation

Payment and delivery of all compensation will be in accordance with the new Home location policies and procedures, as follows:

Job Grading

Band C and Above

The GSK worldwide Job Grading structure and process will be applied to all localised positions

Below Band C

Local grade structures will apply

Salary

Will be managed according to the new Home location business guidelines, as will any Salary Review and/or promotion increases awarded

Bonus

If a Bonus scheme is applicable, a localised employee will participate in the new Home location Bonus scheme appropriate to their job grade

Long Term Incentive

A localised employee will be eligible to participate in the new Home location Long Term Incentive Plans, if appropriate for their job grade.

Benefits

A localised employee will participate in all the new Home location Benefit Plans, i.e. Healthcare Plan, Pension Plan, Company car etc.

Saving Schemes

A localised employee will be eligible to participate in Saving Schemes applicable to the new Home location

Healthcare

An employee localised to a country that does not provide appropriate levels of Healthcare coverage, in line with the old Home location, should be covered by an alternative Company funded plan. This will be dependent on practice in the new Home location.

- 20 -

Pension Plan

An employee localised to a country that does not provide an appropriate Pension Plan, should be covered under an alternative State or Company funded plan. This will be dependent on practice in the new Home location.

Annual Holiday/Vacation Entitlement and Hours of Work

A localised employee's holiday/vacation entitlement and hours of work will be determined by the new Home location's business sector guidelines.

Home Leave (Original Home location)

During a three (3) year transition period the Company will pay for the employee and their dependants to return to their original Home location on two (2) occasions.

A local transportation component of 14 days car hire, to assist with airport transfer costs and local transport during each of the two (2) Home Leave trips, will also be included. Home Leave will be paid as a Lump Sum. Home Leave must be taken from the employee's holiday/vacation entitlement.

Economy class return airfares should be used, however if the flight time to the old Home location is more than 15 hours, an employee and dependants may purchase a Business Class ticket (at the most economical rate). The difference between the Economy and the Business Class ticket can be reclaimed via travel expenses, on production of receipts.

Transition Allowance

A Transition allowance will be paid if the net salary in local currency is less than the net salary level from the original Home location, once differences in the cost of living allowance, location allowance, income tax and social security taxes have been taken into account. This allowance will be paid monthly as a separate allowance, subject to tax and will be phased out over a three (3) year period:

Year 1 100%

Year 2 66%

Year 3 33%

Transition Allowance - Other

Local HR may have to recognise other benefits to be considered for transition purposes, i.e. Schooling, Storage etc.

Before a localisation can proceed HR will need to take the following steps:

Understand the reason for localising the Global Assignee (see Section 13.4 Scope)

Understand the consequences of the Global Assignment Terms and Conditions ceasing, on the localising employee and dependants

- 21 -

Understand the old Home location Terms and Conditions, which will cease on localisation, in comparison to the new Home location Terms and Conditions

The above should be used as the basis for decisions on:

Allowances that are considered for transitioning purposes

How an allowance will be phased out

Home Location Owned Property (Principal Residence)

GSK will provide assistance to localising employees in buying and selling property in line with the Home and Host permanent relocation policies. GSK also operates a Mortgage Assistance Programme.

Immigration

The Company will sponsor and arrange for work permit applications and permanent residency applications for the localised employee as appropriate.

Household Goods Shipment

The Company will pay for the shipment of a Global Assignee's personal and household goods (including personal computers) by surface and sea transport to the new Home location. Shipment expenses covered by the Company include the cost of packing/unpacking, shipping and insuring reasonable household effects

In addition to or instead of surface and sea transport for intercontinental/cross-border moves, the Company will transport by air freight, household goods to the new Home location of up to:

500 lbs. (225 Kilos) or less, for unaccompanied Global Assignees

1000 lbs. (450 Kilos) or less, for accompanied Global Assignees

One (1) air freight shipment, if applicable, should be used for localisation.

Employment Legislation

The employee will be subject to the employment legislation guidelines and policies of the new Home location.

Global Tax Support Service

The Company will pay for the services of a Global Tax Support Service to prepare tax returns for a localised Global Assignee and to provide tax advice on tax matters related to the localisation.

Tax advice will be provided in the year of the localisation and for a further year, if required. This advice will cover all departure and new Home location tax returns that are required.

The localised employee is liable to the new Home location tax rules on Salary, Bonus, Executive Share Plans, Housing support and Educational support.

- 22 -

As is more fully explained in the Appendices addressing GSK Tax Policies, your personal tax liability and our tax support in the year of localization and the subsequent year extends to LTIs. The taxation of LTIs in the context of cross border assignments can be complicated; moreover, assignment related tax matters (tax reporting, withholding and compliance) can extend beyond the actual assignment term because the LIT accrual, vesting and award timeline could span several years beyond the close of an assignment or the localisation. Consequently, you should expect that the tax and support policies we have developed will ensure that you bear your appropriate level of tax on LTIs, and that assignment related home and host country issues may be addressed well beyond the completion of your assignment and the year of localization in the case of LTIs.

For additional information about the Company’s Tax Protection policy, please refer to

Appendix H: Global Tax Support Service

Appendix M: Tax Equalisation/Protection Policy on LTIs

Appendix H: Global Tax Support Service

Overview

This appendix outlines the services provided by the Global Tax Support Service engaged by the Company.

Scope

Global Assignees are covered for these services commencing with the tax year the assignment begins and ending with the calendar or fiscal tax year when the assignment is completed. The Global Assignee may remain in the programme for an extended period following repatriation, at the Company's discretion, in the case of LTI awards which have assignment tax consequences, or if post assignment payments or credits occur.

Tax Return Preparation

After the close of each tax year having assignment tax consequences, the Global Assignee will be contacted by the Global Tax Support Service as necessary so that all required tax returns can be prepared and filed.

The fee for tax return preparation will be borne by the Company as long as it relates to the assignment and is approved by the Company. The cost of any personal income, estate tax, planning consultation or preparation of returns for family members will be the Global Assignee's responsibility.

Global Assignees are required to use the Global Tax Support Service's tax return preparation services. The Company will not reimburse any fees incurred in utilising other services.

- 23 -

Additional Support

In addition to tax return services, the Global Tax Support Service will also provide the following assistance to the Global Assignees:

1.	Pre Assignment Tax Consultation

As soon as practical after approval of the assignment, the Global Assignee will meet with a tax consultant to discuss the tax consequences of the assignment.

The tax consultation will address the following issues:

Home location tax rules and requirements

Tax rules for rental of principal residence

Record keeping requirements

Review of taxability of capital gains and stock option transactions related to the Company's compensation and benefits programmes

Preparation of applicable withholding tax certificates

Explanation of estimated hypothetical tax

Social security tax implications of the assignment

Post Arrival Tax Consultation

As soon as practical after arriving in the assignment location, the Global Assignee will meet with the tax consultant's assignment location tax advisors for a review of the local tax rules, tax return preparation requirements and tax return filing deadlines.
