	 	16.2	 The Executive will acquire 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. The improper disclosure or use of such information or knowledge by the Executive would cause the Group irreparable harm. To protect these
interests, and prevent such harm, the Executive agrees with the Company and GSK plc that the Executive will be bound by the following covenants: 


  

	 	16.2.1	 During the Employment, the Executive will not be employed by, affiliated with (except as the holder, directly
or indirectly, of less than 5 per cent of the shares) work for, or render services similar to those which the Executive is involved during the Employment on behalf of, any firm or business organization that competes or is planning to compete
with the Restricted Business, or render services to, or assist in any way, any competitor of the Group by working on or having any involvement with products or services that are similar to the Restricted Business. 



 

  
 8 














	 	16.2.2	 During the Employment, the Executive will not canvass, solicit or induce any customer, client or vendor of the
Company or any Group Company to become a customer, client or vendor of any other person, firm, or corporation other than the Group with respect to the Restricted Business. After the Executive’s Employment with the Company, the Executive will
not use Confidential Information to canvass, solicit or induce any customer, client or vendor of the Company or any Group Company to become a customer, client or vendor of any other person, firm, or corporation other than the Group with respect to
the Restricted Business. 


  

	 	16.2.3	 During the Restricted Period, the Executive will not interfere or endeavor 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. 



 

	 	16.2.4	 During the Restricted Period, the Executive will not solicit or attempt to solicit any officer, director,
senior employee or senior consultant of the Group to leave the Group to join or perform services on behalf of any other person or entity. 


  

	 	16.3	 Each of the obligations imposed on the Executive by this Section 16 extend to the Executive acting not
only on his own account but also on behalf of any other firm, company or other person and shall apply whether the Executive 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 this
Section 16 is received and held in 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	 Consideration and Reasonableness of Restrictions 



 

	 	17.1	 The Executive acknowledges that the restrictions contained in Section 16 are supported by consideration in
the form of compensation received by the Executive under this Agreement. 


  

	 	17.2	 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. 


  

	 	17.3	 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. 


  

	 	17.4	 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 the Executive in breach of the provisions of this Agreement, the Executive shall promptly advise
the offeror of the existence of the restrictions set forth in Section 16 of this Agreement. 


  

	 	17.5	 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 the Executive relating to the enforcement of
Section 16 above raise the defense 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.

	19	 Successors and Assigns 



 

	 	19.1	 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.

deemed given on the date delivered and any notice sent by courier shall be deemed given on the date delivery is recorded by such courier.

dealt with in it. It contains the whole agreement between the parties relating to the Employment at the date the agreement was entered into (except for those terms implied by law which cannot be excluded by the agreement of the parties). The
Executive acknowledges that he has not been induced to enter into this Agreement by any representation, warranty or undertaking not expressly incorporated into it. 



 

	 	22.2	 Neither party’s rights or powers under this Agreement will be affected if: 



 

	 	22.2.1	 one party delays in enforcing any provision of this Agreement; or

	24	 Withholding 



Anything to the contrary notwithstanding, all payments required to be made by the Company under this Agreement to the Executive, or to his

	25	 Indemnification and Insurance 



 

	 	25.1	 The Company agrees that if the Executive is made a party or is threatened to be made a party to any action,
suit, proceeding or governmental or other investigation by reason of the fact of the Employment or that he is or was a director, officer or employee of the Company or is or was serving at the request of the Company as a director, officer, employee
or agent of another Group Company or entity except for any action instigated by the Company or the Executive (a “Proceeding”), he shall be indemnified by the Company to the fullest extent permitted by applicable law against all
expenses, liabilities and losses reasonably incurred or suffered by the Executive in connection with such a Proceeding (including any tax payable by the Executive as a result of payments made by the Company pursuant to this indemnity), including,
without limitation, payment of expenses incurred in defending a Proceeding prior to the final disposition of such Proceeding; PROVIDED, however, that written notice of such Proceeding is given promptly to the Company by the Executive and the Company
is permitted (where appropriate) to participate in and assume the defence of such Proceeding. The provisions of this Section 25 shall survive the termination of the Employment and shall be in addition to any other rights to indemnification to
which the Executive may from time to time be entitled, whether under any applicable insurance policies or otherwise. 


  

	 	25.2	 The Company will provide the Executive with Legal Expenses Insurance and Directors’ and Officers’
Liability Insurance under the Company’s policy current from time to time in force subject to such cover being available at reasonable commercial rates. 


  


	26	 Collective Agreements – Disciplinary Rules and Procedures 



There are no collective agreements which directly affect the terms and conditions set out in this Agreement. 

The Company’s harassment and bullying policies, disciplinary rules and procedures and grievance procedures, as in force from time to time,

information to other offices the Company may have or to a Group Company or to other third parties whether or not outside the United States for administration purposes and other purposes in connection with the Executive’s Employment where it is
necessary or desirable for the Company to do so.

	29	 Section 409A 



 

	 	29.1	 It is the intention of the parties to this Agreement that no payment or entitlement pursuant to this
Agreement will give rise to any adverse tax consequences to the Executive under Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder, including that issued after the date hereof. The
Agreement shall be interpreted to that end and, consistent with that objective and notwithstanding any provision herein to the contrary, the Company may take any action it deems necessary or desirable to amend any provision herein to avoid the
application of or excise tax under Section 409A, after giving the Executive reasonable notice and opportunity to comment. Further, no effect shall be given to any provision herein in a manner that reasonably could be expected to give rise to
adverse tax consequences under Section 409A of the Code. 


  

	 	29.2	 Any annual cash bonus that the Executive shall become entitled to receive hereunder for any calendar year shall
be paid by the Company at such time and in such manner that annual bonuses are paid to other senior executives of the Company, but not later than the March 15 immediately following the end of the applicable calendar year; provided it shall not
be a breach of this Agreement if payment is made later in the year to the extent the bonus is not determinable by March 15 and payment is made by payroll no later than December 31 of such year. 



 

	 	29.3	 All payments to be made upon a termination of Employment under the Agreement will only be made upon a
“separation from service” under Section 409A of the Code. In no event may the Executive, directly or indirectly, designate the calendar year of payment. To the maximum extent permitted under Section 409A of the Code and its
corresponding regulations, the amounts payable under the Agreement to be made upon termination of Employment are intended to meet the requirements of the short-term deferral exemption under Section 409A of the Code and the “separation pay
exception” under Treas. Reg. §1.409A-1(b)(9)(iii). For purposes of the application of Treas. Reg. §1.409A-1(b)(4) (or any successor provision), each payment in a series of payments to the Executive will be deemed a separate payment.



  

	 	29.4	 Notwithstanding anything in this Agreement to the contrary, in the event that the Executive is deemed to
be a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, any payment under this Agreement that constitutes deferred compensation subject to 409A of the Code and would otherwise commence to be paid as a
result of the Executive’s “separation from service” (as defined in Section 409A of the Code and any Treasury Regulations promulgated thereunder), will not be made to the Executive before the lapse of six months after the date
such payment would have been made but for this Section 29.4. Any payments that are postponed in accordance with this Section 29.4 shall be paid in a lump sum payment within 10 days after the end of the six month period. If the Executive
dies during the postponement period prior to payment of the postponed amount, the amounts withheld on account of Section 409A of the Code shall be paid to the personal representative of the Executive’s estate within 60 days after the date
of Executive’s death. 


  

	30	 Governing Law 



This Agreement shall be deemed a contract made under, and for all purposes shall be construed in accordance with, the laws of the Commonwealth
of Pennsylvania. Each of the parties submits to the exclusive jurisdiction of the Commonwealth of Pennsylvania’s courts as regards any claim or matter under this Agreement.
