 ARTICLE 2 
 GOVERNANCE OF THE COLLABORATION 
 2.1 General Overview. Pursuant to this Agreement, Targacept will undertake and be responsible for the conduct of each Research Program and Early
Development Program, as further discussed in Article 3, the scope of which is the discovery, identification and development of small molecule compounds that meet the Protein Target Profile for the applicable Program, with 

					
			
	EXECUTION VERSION	  	-28-	  	

 
GSK having exclusive options to obtain an exclusive license for certain of such compounds on a worldwide basis, as further discussed in Article 4. The goal
for the collaboration is that, for each Program, (i) a Collaboration Compound is progressed by Targacept through the applicable Research Program, becomes a Development Candidate and is progressed by Targacept through an Early Development
Program through and including completion of the PoC Trial, (ii) two (2) Backup Compound(s) or one (1) Backup Compound and one (1) Follow-On Compound are progressed by Targacept at least to the Candidate Selection Stage or, if
earlier, until exercise by GSK of its Program Option for such Program (except that this clause (ii) is not a goal for the Pain 1 Program) and (iii) following exercise by GSK of its Program Option, GSK further Develops such Progressed
Compounds and commercializes them as Licensed Products. 
 2.2 General Allocation of Responsibilities. Generally, except as otherwise
expressly provided herein, with respect to each Program, Targacept shall be solely responsible for conducting all research, discovery and Development activities, and for all costs and expenses associated therewith, with respect to the corresponding
Research Program during its Research Program Term (except for the Pain 1 Program, for which there is no Research Program) and the corresponding Early Development Programs during their respective Early Development Program Terms and shall have the
right, but not the obligation, to conduct Targacept Post-Exercise Activities after exercise by GSK of its Program Option with respect to such Program. Targacept shall carry out all such activities with respect to each of the Programs pursuant to the
applicable Research Plan and Early Development Plan. Subject to Targacept’s rights with respect to the Targacept Post-Exercise Activities, GSK shall be solely responsible for all development and commercialization activities, and for all costs
and expenses associated therewith, with respect to Product Candidates and Licensed Products. 
 2.3 The Joint Steering Committee.
Promptly and in any event within ninety (90) days after the Effective Date, the Parties shall establish and convene a committee (the “Joint Steering Committee” or “JSC”), which shall (i) have review and
oversight responsibilities with respect to each Research Program and Early Development Program and (ii) serve as a vehicle to facilitate the transfer of information between the Parties with respect to any commercialization activities and the
Product Candidate Commercialization Program, in each case as more specifically provided herein. Each Party agrees to keep the JSC informed of its progress and activities within each Research Program, Early Development Program, and Product Candidate
Commercialization Program.

 2.3.1 Membership. The JSC shall be comprised of at least three (3) and not more than
four (4) representatives (or such other number of representatives as the Parties may agree) from each of GSK and Targacept; provided that the Parties acknowledge and agree that Targacept has specifically negotiated for membership on the JSC as
a benefit under this Agreement and that such membership constitutes a right (which may be waived by Targacept at any time, but only if it does so expressly and in writing) and not an obligation of Targacept. Each Party shall provide the other with a
list of its initial members of the JSC within thirty (30) days after the Effective Date. Each Party may replace any or all of its representatives on the JSC at any time upon written notice to the other Party in accordance with
Section 14.6. Each representative of each Party shall be of the level of Director or higher and shall have expertise in business or pharmaceutical drug discovery and development. Any member of the JSC may designate a substitute to attend and
perform the functions of that member at any meeting of the JSC. Each Party may, in its reasonable discretion, invite non-member representatives of such Party to attend meetings of the JSC as a non-voting participant, subject to the confidentiality
obligations of Article 9. The Parties shall designate a chairperson (each, a “Chairperson”) to oversee the operation of the JSC and prepare minutes as set forth in Section 2.3.3, each such Chairperson to serve a twelve
(12) month term. Unless the JSC determines otherwise, the right to name the Chairperson shall alternate between the Parties, with Targacept designating the first such Chairperson. 
 2.3.2 Meetings. During the Collaboration Term, the JSC shall meet in person or otherwise at least once each Calendar Quarter, and more
frequently as the Parties deem appropriate, on such dates as provided herein or as the Parties shall otherwise agree. Upon the conclusion of the Collaboration Term, the JSC shall meet, in person or otherwise, at least once [********] to provide
Targacept an update regarding GSK’s efforts under the Product Candidate Commercialization Program and otherwise to perform the responsibilities assigned to it under this Agreement; provided, however, that during the period hereunder in which
royalties are owed for a particular Licensed Product, the Parties agree to periodically discuss in good faith increasing the frequency of such ongoing meetings. Meetings of the JSC that are held in person shall alternate between the offices of the
Parties, or such other place as the Parties may agree. The members of the JSC also may convene or be polled or consulted from time to time by means of telecommunications, video conferences, electronic mail or correspondence, as deemed necessary or
appropriate. 

					
			
	EXECUTION VERSION	  	-30-	  	

 2.3.3 Minutes. During the Collaboration Term, the Chairperson shall be responsible for
preparing and circulating minutes within [********] after each meeting setting forth, inter alia, a description, in reasonable detail, of the discussions at the meeting and a list of any actions, decisions or determinations approved and a
list of any issues to be resolved by the Executive Officers pursuant to Section 2.3.4. Such minutes shall be effective only after approved by the JSC. With the sole exception of specific items of the meeting minutes to which the members cannot
agree and which are escalated to the Executive Officers as provided in Section 2.3.4, the JSC shall use commercially reasonable efforts to ensure that definitive minutes of all JSC meetings are finalized within [********]. If at any time during
the preparation and finalization of the JSC minutes, the Parties do not agree on any issue with respect to the minutes, such issue shall be resolved by the escalation process as provided in Section 2.3.4. The decision resulting from the
escalation process shall be recorded by the Chairperson in amended minutes for such meeting. 
 2.3.4 Decision-making.
Generally, except as otherwise expressly provided herein, decisions of the JSC shall be made by consensus, with all of each Party’s representatives, having collectively one (1) vote in all decisions. In the event that the JSC is unable to
reach a consensus decision within [********] after it has met and attempted to reach such decision, then either Party may, by written notice to the other, have such matter referred to the Chief Executive Officer of Targacept, or such other officer
designated by Targacept from time to time, and the Senior Vice President of the Center of Excellence for External Drug Discovery of GSK, or such other person holding a similar position designated by GSK from time to time (collectively, the
“Executive Officers”), for resolution. The Executive Officers shall meet promptly to discuss the matter submitted and to determine a resolution. If the Executive Officers are unable to determine a resolution in a timely manner,
which shall in no case be more than [********] after the matter was referred to them, the matter shall be finally resolved as provided in Sections 2.3.4(a) or 2.3.4(b), subject to Section 2.3.4(c). For clarity, except as provided in
Section 2.3.4(c), no final decision made in accordance with Sections 2.3.4(a) or 2.3.4(b) shall be subject to any further review under Article 14 or under any other provision of this Agreement.

 ARTICLE 3 
 THE CONDUCT OF THE COLLABORATION 
 3.1 Research Programs; Initial Term. The Research Programs shall generally commence as soon as practicable after the Effective Date, and Targacept
shall have commenced the application of its Diligent Efforts for all five (5) Research Programs other than the Pain 1 Program (for which there is no Research Program) by no later than [********]. Subject to the oversight of the JSC, Targacept
shall have responsibility for the conduct of each Research Program, including all scientific, clinical, and regulatory activities, at its sole expense, in accordance in all material respects with the Research Plan therefor. GSK shall have the right
to provide consultation and advice with respect to each Research Program, which shall be considered in good faith by Targacept. 
 3.1.1
Research Program Term. Each Research Program will expire upon the later of: 
 (a) the [********] anniversary of the Effective
Date, unless earlier terminated by the JSC or extended by the mutual written agreement of the Parties (the period from the Effective Date to such expiration date, the “Initial Term”); or 
 (b) if: (i) no Lead has been nominated by Targacept as and determined by the JSC to be a Development Candidate as of the end of the Initial Term;
(ii) a Lead had been designated by Targacept at least [********] prior to the end of the Initial Term; and (iii) GSK pays the Development Candidate Achievement milestone with respect to such Lead within [********] (or, if the end of

					
			
	EXECUTION VERSION	  	-38-	  	

 
the Initial Term [********]) following the end of the Initial Term (clauses (i), (ii) and (iii), collectively, the “Development Candidate
Pursuit Conditions”), at such time after the Initial Term as (A) such Lead shall have been nominated by Targacept as and determined by the JSC to be or not to be a Development Candidate or (B) Targacept shall have determined in
good faith, in accordance with the applicable Development Candidate Criteria and in view of all the data generated on such Lead that such Lead has not or will not satisfy the Development Candidate Criteria (the period beginning with commencement of
a Research Program and ending upon expiration of such Research Program, the “Research Program Term“). 
 Notwithstanding the foregoing, if,
with respect to any Program for which GSK exercises its Program Option, Targacept conducts Targacept Post-Exercise Activities permitted hereunder that constitute Preclinical Activities and extend beyond the Research Program Term determined as
provided above, the period during which Targacept conducts such Targacept Post-Exercise Activities shall constitute an extension of the applicable Research Program Term. 
 3.1.2 Clarifications. Each Research Program shall be conducted by Targacept for the duration of the Research Program Term (subject to the application of Diligent Efforts and to the last paragraph of
Section 3.3.2), unless such Research Program (or Program) is earlier terminated by the JSC. The goal of each Research Program is to identify a Development Candidate and two (2) Backup Compounds or one (1) Backup Compound and one
(1) Follow-On Compound to each Development Candidate. 
 3.2 Early Development Program; Early Development Term. 
 3.2.1 Early Development Programs; Cooperation. An early Development program shall be conducted by Targacept for each Program with respect to
which a Lead is nominated by Targacept as and determined by the JSC to be a Development Candidate during the Research Program Term, which shall include all Development activities for such Development Candidate (including, for clarity, any Backup
Compound or Follow-On Compound that is nominated by Targacept as and determined by the JSC to be a Development Candidate and substituted for another Development Candidate or otherwise), from the Candidate Selection Stage through and including
completion of the IND Studies, one (1) or more Phase 1 Clinical Trials and the PoC Package (with each successive stage being contingent on success at the previous stage), in furtherance of the goal of an Option Compound for each Program (each,
an “Early Development Program”). In addition, if prior to the exercise by GSK of the applicable Program Option, 

					
			
	EXECUTION VERSION	  	-39-	  	

 
Targacept elects in its sole discretion to conduct any further Development activities of any Follow-On Compound that reaches the Candidate Selection Stage
and is then confirmed by the JSC as a Follow-On Compound, such activities shall also constitute part of the Early Development Program. 
 With respect to any Program, at any time during the Early Development Program (prior to conduct of the PoC Trial), Targacept may nominate any Backup Compound or Follow-On Compound for which the Development Candidate Activities have been
completed as, and the JSC may then determine such Backup Compound or Follow-On Compound to be, a Development Candidate in substitution for the then-current Development Candidate. Targacept shall have responsibility for the conduct of each Early
Development Program in accordance in all material respects with the applicable Early Development Plans and shall have sole responsibility for all costs and expenses for each Early Development Program hereunder, subject to the provisions of Sections
2.3.4, 2.3.5 and 3.6.4(c). In addition to GSK’s decision-making rights under Sections 2.3.4 and 2.3.5, GSK shall also have the right to provide consultation and advice with respect to all of such activities, which shall be considered in good
faith by Targacept. The Parties agree to cooperate during the Collaboration Term in identifying and implementing opportunities to reduce the costs incurred in the conduct of the Research Programs and Early Development Programs, including costs of
equipment, consumables such as laboratory supplies and Third Party services such as toxicology, clinical studies or manufacturing services, provided such cooperation does not unduly delay or hamper Targacept in the performance of its activities
thereunder. This cooperation may include exploration of GSK’s [********] or the use of GSK’s [********] or other [********] expertise. 
 3.2.2 If No Development Candidate. For clarity, if there is no Development Candidate that remains in Development for any Program as of the end of the Initial Term and the Development Candidate Pursuit Conditions do not apply,
Targacept shall have no further obligation hereunder in respect of such Program. If the Development Candidate Pursuit Conditions apply, (i) Targacept shall continue to conduct research on the applicable Lead to complete the Development
Candidate Activities and (ii) solely if such Lead is then nominated by Targacept (acting in good faith, in accordance with the applicable Development Candidate Criteria and in view of all the data generated on such Lead) as and determined by
the JSC to be a Development Candidate, (A) an Early Development Program solely for such Development Candidate shall be conducted by Targacept as provided in Section 3.2.1 and in accordance with the relevant provisions of this Agreement and
(B) if, as of the date of such JSC determination, there are not two (2) Progressed 

					
			
	EXECUTION VERSION	  	-40-	  	

 
Compounds in such Program in addition to such Development Candidate and Targacept determines there to be up to two (2) Collaboration Compounds in such
Program that qualify as Backup Compounds to such Development Candidate or one (1) Collaboration Compound in such Program that qualifies as a Backup Compound and one (1) Collaboration Compound in such Program that qualifies as a Follow-On
Compound to such Development Candidate, Targacept shall nominate it or them, as the case may be, for JSC consideration; provided that, notwithstanding anything to the contrary set forth herein, Targacept shall have no obligation to conduct any
further research or Development activities with or otherwise to progress any such Backup Compound or Follow-On Compound. If such Lead is not nominated by Targacept as described above as and determined by the JSC to be a Development Candidate, there
shall be no Early Development Program with respect to such Program and Targacept shall have no further obligation hereunder in respect of such Program. 
 3.2.3 Early Development Program Term. Each Early Development Program will start at the earlier of commencement of activities under such Early Development Program or adoption of the first Early
Development Plan by the JSC for such Early Development Program and will terminate upon the earliest of: 
 (a) the date on which (i) GSK
exercises its Program Option for the applicable Program or (ii) the Option Period for such Program expires with the Program Option unexercised; 
 (b) the date on which the JSC approves the termination of such Early Development Program; 
 (c) [********]
from the start of such Early Development Program; or 
 (d) the date on which the JSC determines that a Development Candidate for which the
PoC Trial was conducted failed to meet the PoC Criteria, unless both (i) such date is before the end of the Initial Term and (ii) Targacept elects by written notice to GSK within [********] after such determination to continue such Early
Development Program by continuing to Develop a Backup Compound for a period specified in such notice (the period of such Early Development Program, the “Early Development Program Term”). 
 Notwithstanding the foregoing, with respect to any Program for which: 
 (x) the Early Development Program Term ends under the circumstances described in clause (d) above, if, at the time of JSC determination that the Development Candidate for which the PoC Trial was conducted failed
to meet the PoC Criteria, there exists in such Program a Follow-On Compound: 
 (i) for which Targacept is then conducting an ongoing Phase 1
Clinical Trial, then: 
 (A) such Follow-On Compound shall become a Development Candidate; 

					
			
	EXECUTION VERSION	  	-41-

 (C) notwithstanding
Section 6.4.1, Targacept shall be eligible for all milestones based on the achievement of Milestone Events thereafter with respect to such Development Candidate as if it were the first Development Candidate in such Program (i.e., without regard
to the failure of the initial Development Candidate); or 
 (ii) for which GSK has paid the milestone for the Milestone Event [********] but
for which clause (i) above does not apply, then: 
 (A) such Follow-On Compound shall become the Lead in such Program; 
 (B) Targacept shall continue to conduct research solely with respect to such Lead and such continued research shall effect the continuation of the Early
Development Program Term solely with respect to such Lead, and not with respect to any other compound in such Program, until such time as (1) Targacept has completed the [********] for such Lead or (2) Targacept shall have [********] the
applicable Development Candidate Criteria and [********] the data generated on such Lead [********] the Development Candidate Criteria; and

 3.3 Objectives; Targacept Diligence and Responsibilities. 
 3.3.1 Targacept Diligence. The goal of the collaboration is for Targacept to identify and develop a Leading Compound as an Option Compound
for each Program, for a total of [********] Option Compounds for further Development and commercialization by GSK in the Territory (and, with respect to Co-promotion Products with respect to which Targacept exercises its Co-promotion Right, by
Targacept and GSK in the United States) under the terms of this Agreement and, subject to the limitations on Targacept’s obligations after the exercise of a Program Option by GSK as set forth in Section 3.6.5, to have identified two
(2) Backup Compounds or one (1) Backup Compound and one (1) Follow-On Compound to each Option Compound, and progressed, in addition to progressing an Option Compound to the completion of the PoC Package, each Backup Compound and
Follow-On Compound to the Candidate Selection Stage, all in accordance with this Section 3.3.1. For each Program, Targacept shall use its Diligent Efforts to carry out and conduct the Research Program during the applicable Research Program Term
in accordance in all material respects with the applicable Research Plan (except that the Pain 1 Program shall not have a Research Program) and the Early Development Program during the applicable Early Development Program Term in accordance in all
material respects with the applicable Early Development Plans. To that end, Targacept shall dedicate to each Research Program and Early Development Program resources, and allocate personnel with an appropriate level of education, experience and
training, consistent with the standard of Diligent Efforts applicable to Targacept. 
 3.3.2 Targacept Diligence Failure Event;
Consequences. Subject to the last paragraph of this Section 3.3.2, in the event that, with respect to any Program, Targacept materially fails to conduct (i) the Research Program in the applicable Research Program Term, or (ii) the
Early Development Program in the applicable Early Development Program Term, in each case in accordance with its diligence obligations under Section 3.3.1, then GSK shall have the right to allege a failure of diligence on the part of Targacept
(a “Targacept Diligence Failure Event”) by written notice to Targacept referencing this Section 3.3.2, describing in reasonable detail the alleged Targacept Diligence Failure Event and stating its intention to pursue its remedy
under this Section 3.3.2 if not cured; provided that in no event shall any act or failure to act by Targacept following receipt of such notice from GSK constitute an admission or create any implication that a Targacept Diligence Failure Event
has in fact occurred. Subject to Section 3.3.3, upon receipt of such notice of a Targacept Diligence Failure Event, Targacept shall have a period of [********] in which to cure such Targacept Diligence Failure Event or, if Targacept has during
such [********] period commenced and diligently continued 

					
			
	EXECUTION VERSION	  	-45-	  	

 
conducting activities designed to cure such failure but such cure is not possible during such [********]-day period, Targacept shall have an additional
[********] in which to cure such Targacept Diligence Failure Event. Upon conclusion of the applicable cure period, if Targacept has not cured such Targacept Diligence Failure Event, GSK shall have the right, exercisable not later than [********]
after the end of the applicable cure period, unless extended by the written agreement of the Parties, to immediately (a) terminate such Research Program or Early Development Program with respect to which the Targacept Diligence Failure Event
relates; and (b) obtain the remedy set forth in one of the two paragraphs below (whichever is applicable), which such remedy shall be the sole and exclusive remedy to GSK for such Targacept Diligence Failure Event. The Parties understand and
agree that, due to the nature of the collaboration under this Agreement, damages to GSK resulting from a material breach by Targacept of its diligence obligations under this Agreement would be difficult to calculate accurately, and thus the remedy
set forth below represents a rational relationship between the damages from the material breach of diligence on the one hand and the cumulative loss to GSK of its expectation interest and its lost investment and lost potential return on investment
due to the upfront and milestone payments made hereunder. 
 In the case of a Targacept Diligence Failure Event of the type described in
clause (i) above (but where there is at least one (1) Collaboration Compound from the applicable Program that has been nominated by Targacept as and determined by the JSC to be [********] as of the end of the applicable cure period) or
clause (ii) above, that is uncured within the applicable cure period: (A) Targacept shall grant and does hereby grant, effective only in such event (subject to Section 3.3.3), to GSK an exclusive, worldwide license (with the right to
sublicense) under all of Targacept’s rights and interest in and to the Targacept Diligence Failure Technology to research, develop, and commercialize in the Field the applicable [********] (i.e., the [********] that is the subject of the
breached Early Development Program and up to [********] or the [********] with respect to such [********], but only if and to the extent any such [********] or [********] have previously been nominated by Targacept as such and determined by the JSC
to be such, as provided herein) and to make, have made, use, sell, offer for sale, and import in the Field products incorporating any such up to [********] or any formulation or dosage or delivery form thereof, including, without limitation, any
metabolite, prodrug, ester, salt, crystalline polymorph, hydrate or solvate thereof; and (B) GSK shall pay to Targacept a [********] percent ([********]%) royalty on the annual Net Sales of any such products. [********] or other [********]
shall be [********] on account of the exclusive license described above and the grant of such license shall not count against any of GSK’s Program Options; provided, however, once such a license is triggered as provided in this
Section 3.3.2, Targacept shall be released from all obligations hereunder with respect to the corresponding Program. 

					
			
	EXECUTION VERSION	  	-46-	  	

 In the case of a Targacept Diligence Failure Event of the type described in clause (i) above (where
there is no Collaboration Compound from the corresponding Program that has been nominated by Targacept as and determined by the JSC to be [********]) that is uncured within the applicable cure period, (x) Targacept shall grant to GSK and does
hereby grant effective only in such event (subject to Section 3.3.3), an exclusive, worldwide license (with the right to sublicense) under all of Targacept’s rights and interest in and to the Targacept Diligence Failure Technology to
research, develop, and commercialize in the Field [********] in the applicable Program and up to [********] in such Program to be selected by GSK by written notice to Targacept given within [********] after the end of the applicable cure period, and
to make, have made, use, sell, offer for sale, and import in the Field products incorporating any of such [********], including any formulation or dosage or delivery form thereof, and including, without limitation, any metabolite, prodrug, ester,
salt, crystalline polymorph, hydrate or solvate thereof, and (y) GSK shall pay to Targacept a [********] percent ([********]%) royalty on the annual Net Sales of any such products. [********] or other [********] shall be [********] on account
of the exclusive license described above, and the grant of such license shall not count against any of GSK’s Program Options; provided however, once such a license is triggered as provided in this Section 3.3.2, Targacept shall be released
from all obligations hereunder with respect to the corresponding Program. 
 Notwithstanding anything herein to the contrary, in no event
shall any acts or omissions of Targacept, individually or collectively, in connection with any (i) Targacept Post-Exercise Activities, (ii) research or Development activities with respect to any Backup Compound beyond Candidate Selection
or, except with respect to Development pursuant to Section 3.7.4, Follow-On Compound beyond Candidate Selection, (iii) Development or commercialization of any Refused Candidate, Refused Candidate Product or Returned Licensed Product or
(iv) other activity that constitutes a right but not an obligation of Targacept hereunder give rise to or otherwise support in any respect a Targacept Diligence Failure Event. 
 3.3.3 Dispute. In the event that Targacept in good faith disputes either the alleged Targacept Diligence Failure Event or whether the
alleged Targacept Diligence Failure Event has been cured or cured on a timely basis, Targacept shall have the right to pursue such dispute in accordance with Section 14.1. During the entire time pending the final resolution of any such dispute,
including without limitation, during mediation or arbitration, settlement negotiations or any other related legal proceeding, Targacept 

					
			
	EXECUTION VERSION	  	-47-	  	

 
shall not grant any license to any Third Party under the Targacept Diligence Failure Technology with respect to the same subject matter, which would conflict
or otherwise interfere with the potential exclusive license to GSK. 
 3.3.4 Targacept’s Responsibilities. With respect to
each Program, and without limiting or modifying any obligation of Targacept expressly provided in any other relevant provision of this Agreement, during the applicable Research Program Term and Early Development Program Term and consistent in all
material respects with the applicable Research Plan or Early Development Plan, as updated or amended from time to time, subject to the application and limitations of its Diligent Efforts and the last paragraph of Section 3.3.2, Targacept shall:

 (a) manufacture, or have manufactured, the Collaboration Compounds prior to GSK’s exercise of its Program Option with respect
thereto, including required bulk drug substance and clinical materials; 
 (b) conduct all research and development activities it reasonably
determines are required, consistent with this Agreement, to identify and progress Progressed Compounds to [********]. 
 (c) conduct the
Preclinical Activities and, if a Collaboration Compound is nominated by Targacept as and determined by the JSC to be a Development Candidate, IND Studies, one (1) or more Phase 1 Clinical Trials and through and including the completion of the
PoC Package for such Development Candidate, with each successive stage of Development being contingent on success at the previous stage; 
 (d) conduct [********] of each Development Candidate that is the subject of an Early Development Program and is expected to enter or has moved into a PoC Trial in a manner reasonably designed to [********]; 
 (e) consider in good faith all reasonable suggestions received from GSK regarding any Research Program or Early Development Program; and 
 (f) perform such other obligations with respect to each Research Program and each Early Development Program as the JSC may assign to Targacept from time
to time, subject to Section 2.3.4(a). 

					
			
	EXECUTION VERSION	  	-48-	  	

 3.4 Reports; Publication of Clinical Trial Results. 
 3.4.1 Reports. During the Research Term and the Early Development Term, Targacept shall provide reasonable progress updates [********] the
JSC on the status of each Research Program and Early Development Program, including as and where appropriate summaries of data associated with Targacept’s research and development activities, updates with regard to its manufacturing plans and
activities, and an assessment of the likelihood of and timetable for completion of the respective Programs and advancement of compounds to the next phase of research or Development, as applicable. Targacept shall use reasonable efforts to provide
any such written summaries to JSC members at least [********] days in advance of the applicable JSC meeting. 
 3.4.2 Publication
of Clinical Trials Results. Each of GSK and Targacept shall have the right to publish data or results from any Clinical Studies conducted by such Party, without requiring the consent of the other Party; provided that, after the exercise of its
Program Option for a particular Program, (i) GSK shall also have the right to publish such clinical (but not preclinical) data or results generated by Targacept with respect to the Product Candidates in such Program [********] ([********]
subject to compliance with the process set forth in Section 9.6.2) and (ii) Targacept shall not have the right to publish any such clinical data or results with respect to the Product Candidates in such Program without the prior consent of
GSK, not to be unreasonably withheld, conditioned or delayed. The Parties shall discuss and reasonably cooperate in order to facilitate the process to be employed in order to ensure the publication of any such clinical data and results on the
clinical trial registry of each Party, if and as required and applicable. In addition, each Party shall provide the Joint Patent Committee at least [********] prior notice to review any proposed publication of such clinical data or results for the
purposes of enabling the preparation of any necessary Patent filings. 
 3.5 Research Plan and Collection of Data. 
 3.5.1 Research Plan. Each Research Program will be carried out by Targacept pursuant to a research plan (the “Research
Plan”), which will outline, as appropriate: (i) discovery and research activities in connection with the identification and preclinical screening of Collaboration Compounds, including lead generation and lead optimization programs;
(ii) identification and optimization of Backup Compound(s) or Follow-On Compound(s) and (iii) estimated timelines for completion of the studies and activities to be undertaken by Targacept thereunder. The outline for the Research
Plans shall be the cascade identified by the Parties as of the 

					
			
	EXECUTION VERSION	  	-49-	  	

 
Effective Date as the outline for the Research Plans. The outlined Research Plans will be finalized for review by the JSC as soon as practicable
following the Effective Date, and thereafter shall be reviewed and modified as necessary at each meeting of the JSC (and at any other time upon the request of either Party) as appropriate to reflect material scientific or commercial developments and
changes. Each Research Plan shall be updated by Targacept as needed to reflect material events or changes, but at least once per Contract Year, and all such updates shall be submitted to the JSC for its review and comment. It is expected that the
level of detail required for each Research Plan will vary depending on the state of progression of Targacept’s efforts with regard to the corresponding Research Program (i.e., Research Programs at an earlier stage of development will have more
detail in their respective Research Plans). It is understood by the Parties that the Research Plan is intended to be an outline of expected activities and does not represent a detailed embodiment of all activities that may be conducted under a given
Research Program. 
 3.5.2 Data Integrity. 
 (a) Targacept acknowledges the importance to GSK of ensuring that the Research Programs are undertaken in accordance with the following good data
management practices: 
 (i) data are being generated using sound scientific techniques and processes; 
 (ii) data are being accurately and reasonably contemporaneously recorded in accordance with good scientific practices by persons conducting
research hereunder; 
 (iii) data are being analyzed appropriately without bias in accordance with good scientific practices;

 (iv) data and results are being stored securely and can be easily retrieved; and 
 (v) where, pursuant to then-existing policies and procedures, Targacept’s senior management documents in writing its key decisions, it will
use reasonable efforts to follow its internal procedures and policy, as applicable, so as to demonstrate or reconstruct key decisions made by such senior management during the conduct of the research and development activities under this Agreement.

					
			
	EXECUTION VERSION	  	-50-	  	

 (b) Targacept agrees that it shall use reasonable efforts to carry out the Research Programs and Early
Development Programs so as to collect and record any data generated therefrom in a manner consistent with the above requirements as set forth in clause (a) above. 
 3.6 Target Product Profiles; Development Candidate Selection; Backup Compounds and Follow-On Compounds. 
 3.6.1 Target Product Profiles. For each Program, a draft Target Product Profile shall be prepared by [********] and provided to [********] not later than [********] following the nomination by Targacept of a Development
Candidate for such Program. [********] shall thereafter revise such TPP, in consultation with [********], in order to prepare the TPP for presentation to the JSC for adoption at its next scheduled meeting, subject to Section 2.3.4(b); provided
that the TPP for each Program shall (i) be consistent with and not include or contemplate a target or profile different from the Indication and Protein Target Profile applicable for such Program and (ii) set as the objective for the
Program [********], but not necessarily [********] to pharmaceutical commercialization. [********] may, in consultation with [********], update any TPP from time to time to specifically address the particular qualities and features of a particular
Development Candidate or otherwise to reflect any material event or change; provided that no such TPP shall be changed after [********] following [********] receipt of notice of [********] completion of [********] a Development Candidate in such
Program in any manner that would, in any material respect, increase the obligations of Targacept hereunder or make such obligations more costly or difficult to satisfy. It is understood and agreed that (A) the Target Product Profile is
aspirational in nature, (B) any given Development Candidate may not meet [********] of a TPP, and (C) certain features of the TPP may only apply to [********] of a given Development Candidate (such as [********] of a [********] etc.).

					
			
	EXECUTION VERSION	  	-51-	  	

 3.6.2 Nomination and Determination of Development Candidates, Back-Up Compounds and Follow-On
Compounds.  
 (a) For each Program, Targacept shall in its sole discretion select a Collaboration Compound that it determines has
completed the Development Candidate Activities and has achieved all or substantially all of the Development Candidate Criteria or is otherwise appropriate for nomination as a Development Candidate, if any, and shall nominate to the JSC such
Collaboration Compound for determination as a Development Candidate. Subject to Section 2.3.4(a), the JSC shall review all relevant information and study results concerning each such proposed Development Candidate and, if it determines that a
proposed Development Candidate has completed the Development Candidate Activities and satisfies all or substantially all of the material Development Candidate Criteria, shall determine such proposed Development Candidate to be a Development
Candidate. In addition, substitutions of one Development Candidate for another shall be permitted, to the extent provided in Section 3.2.1, subject to Section 2.3.4(a). 
 (b) With respect to the Leading Compound (which, may include, if applicable, the Development Candidate) for each Program, Targacept shall in its sole
discretion select up to (i) two (2) Collaboration Compounds that it determines qualify as Backup Compounds or (ii) one (1) Collaboration Compound that it determines qualifies as a Backup Compound and one (1) Collaboration
Compound that it determines qualifies as a Follow-On Compound (or, solely in the case of the Pain 2 Program, [********] Collaboration Compounds that it determines qualify as Follow-On Compounds), in each case, if any, and for nomination as and for
determination by the JSC to be a Backup Compound or Follow-On Compound, as the case may be. The JSC shall review all relevant information and study results concerning each such proposed Backup Compound or Follow-On Compound and, if it determines
that it qualifies as such, shall determine such proposed Backup Compound or Follow-On Compound to be a Backup Compound or Follow-On Compound, as the case may be (it being understood by the Parties that, as reflected in the definition of Follow-On
Compound, to qualify under this Agreement as a Follow-On Compound to a particular Leading Compound, a Collaboration Compound must be or be reasonably expected to be [********] such Leading Compound, [********] any Backup Compound to such Leading
Compound, and, in the case of the Pain 2 Program, [********] any other Follow-On Compound). Upon [********], the JSC shall confirm, based on the data and results provided by Targacept, whether a previously determined Follow-On Compound continues to
qualify as a Follow-On Compound, subject to Section 2.3.4(b). 

					
			
	EXECUTION VERSION	  	-52-	  	

 (c) From time to time prior to (i) [********], with respect to a Backup Compound, or
(ii) meeting the [********], with respect to a Follow-On Compound, Targacept may nominate alternative Collaboration Compounds for a determination by the JSC to be a Backup Compound or a Follow-On Compound, as the case may be, in substitution
for a previously determined Backup Compound or Follow-On Compound. 
 3.6.3 Decision whether to pursue Follow-On Compounds.
With respect to the Leading Compound (which may be, if applicable, the Development Candidate) for each Program, Targacept shall have the right, but not the obligation, to conduct research and development to identify a Follow-On Compound (or, solely
in the case of the Pain 2 Program, up to [********] Follow-On Compounds) for such Program. 
 3.6.4 Preliminary PoC Plan; Final PoC
Criteria and PoC Trial. 
 (a) At the time of, and as part of the process of (i) nomination and determination of a Development
Candidate or (ii) confirming that a Follow-On Compound determined prior to [********] continues to be a Follow-On Compound upon [********], the Parties, through the JSC or JPS, shall discuss and agree upon the appropriate preliminary
development strategy and a preliminary plan for meeting the PoC Criteria, including the possible trial design and protocol for the PoC Trial and associated costs and timelines, it being understood that such trial design and timelines are merely
provisional and preliminary and subject to modification (the “Preliminary PoC Plan”). Targacept shall have the right to reasonably rely on such Preliminary PoC Plan in undertaking its Phase 1 Clinical Trials of such Development
Candidate or Follow-On Compound. Notwithstanding the foregoing and Targacept’s discretion in the overall conduct of the Research Programs and Early Development Programs, the final PoC Criteria and the final PoC Trial for such Development
Candidate or Follow-On Compound shall be subject to the further design of the JPS and the review and approval of the JSC, and subject to Section 2.3.4(b). 
 (b) [********], in consultation with [********], shall ensure that the design and content of the PoC Trial and the content of the PoC Criteria are presented to the JSC for approval, subject to Section 2.3.4(b),
within [********] following Targacept’s completion of a Phase 1 Clinical Trial (multiple rising dose) of the applicable Development Candidate. 

					
			
	EXECUTION VERSION	  	-53-	  	

 (c) With respect to each Program, if the total [********] costs and [********] expenditures for the PoC
Trial (or, with respect to a Follow-On Compound, the equivalent of a PoC Trial) exceed [********] (as [********] from [********]): (i) the portion of such costs and expenditures which exceeds such limit shall be [********] for all or any
portion of such excess; (ii) with respect to the PoC Trial, the lesser of (A) [********] of such aggregate amount [********] and (B) [********] will be [********] for such Program for which such PoC Trial is being conducted,
[********] for such Program; and (iii) with respect to the equivalent of a PoC Trial for a Follow-On Compound, the lesser of (A) [********] of such aggregate amount [********] and (B) [********] will be [********] toward the
[********] with respect to such Follow-On Compound. As used in this Section 3.6.4(c), (1) [********] shall include [********] those costs and expenditures which are attributable [********] the PoC Trial (or, in the case of a Follow-On
Compound, the equivalent of a PoC Trial) [********] (including, for clarity and without limitation, [********] costs for [********] therefor) and (2) [********] shall be [********]. 
 3.6.5 Targacept Rights to Conduct Post-Option Exercise Activities. 
 Notwithstanding anything in this Agreement to the contrary and without intending to limit or otherwise modify Targacept’s rights or responsibilities prior to GSK’s exercise of a Program Option, after the
exercise by GSK of its Program Option for a given Program: 
 (a) Targacept shall have the right, but not the obligation, to conduct research
and development to identify a Follow-On Compound (or, solely in the case of the Pain 2 Program, up to [********] Follow-On Compounds); 
 (b) with respect to each Backup Compound or Follow-On Compound for such Program, if such Backup Compound or Follow-On Compound has not [********] as of the exercise of such Program Option by GSK, Targacept shall [********] such Backup
Compound or Follow-On Compound to the [********]; 
 (c) with respect to a Follow-On Compound (whether nominated as such and determined to
be such prior to or after exercise by GSK of its Program Option), Targacept shall have the right (unless the JSC determines at (but not after) the [********] that such compound no longer qualifies as a Follow-On Compound), but not the obligation, to
[********] such Follow-On Compound [********] up to [********] the Follow-On Compound; provided that each such Follow-On Compound shall [********] be subject to [********]; and 

					
			
	EXECUTION VERSION	  	-54-	  	

 (d) upon GSK’s prior written approval (which, for clarity, may be evidenced by the unanimous
approval by the JSC, in which event such approval may occur at a meeting), Targacept shall have the right, but not the obligation, to conduct research and development on any Backup Compound up to completion of the equivalent of the PoC Trial and PoC
Package for the Backup Compound; provided that each such Backup Compound shall automatically be subject to GSK’s previously exercised Program Option; and 
 (e) upon GSK’s prior written approval (which, for clarity, (i) may be evidenced by the unanimous approval by the JSC, in which event such approval may occur at a meeting, and (ii) shall not be
unreasonably withheld, conditioned or delayed (it being understood that it would be reasonable for GSK or its representatives on the JSC to withhold, condition or delay its approval if GSK reasonably expects that such research and development would
[********] such Product Candidate for [********]), Targacept shall have the right, but not the obligation, to conduct research and development on any Product Candidate for one or more Additional Indications. 
 The activities described in clauses (a) – (e) above are collectively the “Targacept Post-Exercise Activities.” Each Targacept
Post-Exercise Activity that is a Clinical Study designed to achieve Other Product Candidate PoC shall be designed by the JPS (or the JSC), subject to Section 2.3.4(b). 
 3.6.6 Ongoing Review. The Early Development Plan with respect to a Development Candidate (or, if applicable, other Progressed Compound),
including the design and content of the PoC Trial, will be reviewed as necessary at each meeting of the JPS (and at any other time upon the request of either Party) and may be modified by the JPS or JSC as appropriate to reflect material scientific
or commercial developments, subject to Section 2.3.4(b). 
 3.7 Early Development Plans and Conduct of Early Development Programs. 

 3.7.1 Establishment, Review and Approval of Early Development Plans. 
 (a) For each Development Candidate (or other Progressed Compound that reaches the Candidate Selection Stage, but only for which continued Development is
to be conducted by Targacept pursuant to the terms of this Agreement (including, without limitation, after exercise by GSK of its Program Option, Section 3.6.5)), the JSC shall review and discuss Targacept’s 

					
			
	EXECUTION VERSION	  	-55-	  	

 
proposed plan for IND Studies and Phase 1 Clinical Trials and other related Development activities. Based on these discussions, Targacept will prepare a
detailed plan for the Development of the Development Candidate or, if applicable, other Progressed Compound (an “Early Development Plan”) for review by the JSC. For clarity, it is contemplated that, if any Program contains more than
one Progressed Compound that (i) reaches the Candidate Selection Stage (by way of example, but without limitation, a Development Candidate and a Follow-On Compound) and (ii) is developed further by Targacept, each such Progressed Compound
would have its own Early Development Plan. 
 3.7.2 Evaluation of PoC Trial Results. Following the conduct of (i) the PoC
Trial for any Development Candidate, in the event that it determines that such Development Candidate meets the PoC Criteria, Targacept shall promptly notify GSK, in writing. The JSC will, at a special ad hoc meeting to be scheduled as soon as
practicable, confirm that such Development Candidate meets the PoC Criteria. Targacept shall thereafter provide to GSK, or make available to GSK at Targacept’s offices or another mutually acceptable location, the PoC Trial Report as set forth
in Section 4.2. 
 3.7.3 Timing for Providing PoC Trial Report. Targacept shall endeavor to provide GSK with a good faith
estimate of the time that such PoC Trial Report will be available at least [********] in advance. In the event that such estimate of delivery date is found to be more than [********] off target date, GSK shall have [********] for the Option Period.

 3.7.4 Development of Follow-On Compound under Circumstances of Section 3.2.3(x). Without limiting the rights of
Targacept with respect to Follow-On Compounds pursuant to any other provision hereof, in the event that a Follow-On Compound in a given Program becomes a Development Candidate under the circumstances described in Section 3.2.3(x), then
Targacept shall have the obligation to use its Diligent Efforts to Develop such Development Candidate (but shall have no obligation with respect to any other compound in such Program) for the remainder of the applicable Early Development Program
Term. 
 3.8 Regulatory Matters. 
 3.8.1 Ownership. Targacept shall own and maintain all regulatory filings for Collaboration Compounds developed pursuant to this Agreement, including all INDs. Upon exercise by GSK of any Program Option, Targacept shall

Technology available to Targacept solely for the limited purposes of conducting such Research Program or Early Development Program, subject in all cases to any existing obligations GSK may have to any Third Party and to the terms and conditions of
this Agreement. 
 3.11 Subcontracting. Each Party shall have the right to engage Third Party subcontractors (which, may also include
Third Party academic collaborators) to perform certain of its obligations under this Agreement. Any subcontractor to be engaged by a Party to perform a Party’s obligations set forth in the Agreement shall meet the qualifications typically
required by such Party for the performance of work similar in scope and complexity to the subcontracted activity. Notwithstanding the foregoing, either Party engaging a subcontractor hereunder (including for the performance of Clinical Studies)
shall remain responsible and obligated for such activities and shall in all cases retain or obtain any and all intellectual property created by such subcontractor in the conduct of, and that is directly related to, such subcontracted activity, at
least on a non-exclusive or option to license basis, at the sole cost and expense of the Party engaging such subcontractor. To the extent that (i) any such subcontracted work is designed to involve the conception of new compositions of matter
or method of use or treatment for an Indication and (ii) an assignment, an exclusive commercial license or a first or exclusive option to acquire an exclusive commercial license cannot be obtained with respect to such intellectual property from
such subcontractor, prior to entering into such arrangement with such subcontractor, such Party shall bring such matter to the Joint Patent Committee in writing in a timely fashion in order to seek the review and prior unanimous written consent from
the Joint Patent Committee (which, for clarity, may occur at a meeting) to enter into such an arrangement, such consent not to be unreasonably withheld, conditioned or delayed. To the extent that any exclusive license to such intellectual property
from such subcontractor would be necessary or reasonably useful to further Develop or commercialize Licensed Products for any of the 

					
			
	EXECUTION VERSION	  	-58-	  	

 
Indications hereunder, Targacept shall be solely responsible for satisfying all such license costs and fees of any type or kind to be owed to such Third
Party contractor, including without limitation, upfront fees, annual fees, milestone payments and royalties, to the extent any such intellectual property pertains to the use of a Progressed Compound for an Indication of a Program hereunder, or to
the method of use, method of manufacture or composition of matter of any Progressed Compound that would be licensed to GSK hereunder by the exercise of a Program Option. 
 3.12 Non-Commercial Supply of Compounds. Targacept shall supply to GSK reasonable quantities of bulk active Development Candidate or other Progressed Compound as reasonably required for any Supplemental
Activities permitted hereunder. The price for supply by Targacept of such quantities of Development Candidate or other Progressed Compound shall be [********]. Following GSK’s exercise of a Program Option with respect to any Program:
(i) Targacept shall transfer to GSK any then existing “on-hand” supplies of the Product Candidates subject to the Program Option exercised by GSK (provided that Targacept may retain sufficient quantities of any such Product Candidate
that is a Backup Compound or Follow-On Compound for which Targacept has the right to conduct Targacept Post-Exercise Activities) for a price equal to [********]; and (ii) the Parties will work together to assign any Third Party manufacturing
arrangements with respect to such Product Candidates to GSK; or (iii) where an assignment is not practicable or otherwise not preferable to GSK, Targacept will cooperate in good faith with GSK in order to facilitate a suitable manufacturing
arrangement between GSK and any Third Party manufacturer with which Targacept has a business or contractual relationship for manufacture or supply of such Product Candidates.

 ARTICLE 4 
 GSK’S PRODUCT OPTION RIGHTS 
 4.1 Program Options. 
 4.1.1 Scope of Program Option. Targacept hereby grants to GSK with respect to each Program the exclusive right, exercisable at GSK’s
sole discretion in accordance with Section 4.3, to elect to obtain exclusive worldwide rights to continue to Develop and commercialize the Option Compound in such Program, if any (and, if there is an Option Compound, the other up to two
(2) (or, solely in the case of the Pain 2 Program, up to [********] Progressed Compounds in such Program that have been nominated by Targacept as such and determined by the JSC to be such as provided herein, if any), as Product Candidates and
Licensed Products under the terms and conditions set forth in this Agreement (each such right to elect, a “Program Option”). Such Option Compound, together with the other up to two (2) Progressed Compounds in such Program, if
any, are included within and subject to a single Program Option exercise. For clarity, the exercise by GSK of a Program Option with respect to a given Program shall be specific to the Program’s set of Progressed Compounds only. 
 4.1.2 Option Compound and Other Progressed Compounds. Following exercise of its Program Option with respect to any Program and pursuant to
the resulting exclusive worldwide license to GSK in accordance with the terms and conditions of Article 5, GSK may, in its sole discretion but subject to its obligation to use Diligent Efforts and Section 5.3.3, (i) [********] the other
Progressed Compounds, if any, [********] for continued Development and commercialization as and into a Licensed Product, or (ii) Develop either or both of the other Progressed Compounds in addition to the Option Compound and commercialize it or
them as and into Licensed Products. 
 4.1.3 No Inconsistent License Grant. With respect to each Program, during the Research
Program Term and any Early Development Program Term, Targacept will not grant to any Third Party rights to any Targacept Technology that are inconsistent with or that would interfere with the grant of the license that would result from the exercise
of the Program Option by GSK hereunder. For the avoidance of doubt, the Parties understand and agree that, with respect to each Program, GSK’s Program Option, as described herein and subject to the terms hereof, shall be an exclusive option
with respect to the Progressed Compounds in such Program and until such time (if any) as (i) GSK declines to exercise or permits to lapse its Program Option or (ii) such Program’s 

					
			
	EXECUTION VERSION	  	-60-	  	

 
Early Development Program Term (or, if none, such Program’s Research Program Term) expires without there being an Option Compound), Targacept shall not
have the right to offer or negotiate with any Third Party with respect to the grant to such Third Party of any right or license or other encumbrance of any kind in or to any of the Progressed Compounds in such Program or the relevant Targacept
Technology. Subject to the effect of Section 5.5, each Program Option exercised by GSK shall be irrevocable. 
 4.2 PoC Trial
Reports. Once a Development Candidate has been determined to meet the PoC Criteria by the JSC to be an Option Compound, Targacept shall, within [********] of such occurrence (unless impractical depending on the nature of the applicable PoC Trial
and the data generated thereunder), provide or make available to GSK at Targacept’s offices or another mutually acceptable location a data package containing all analysis, results [********] from the PoC Trial for such Option Compound, as well
as any previously undisclosed preclinical or clinical data generated or any related correspondence or information received from or sent to any Regulatory Authority relating to the Progressed Compounds then known to be subject to the Program Option,
in each case to assist and enable GSK to make its decision on whether to elect to exercise its Program Option (the “PoC Trial Report”). For clarity, the PoC Trial Report need not include the final report from any particular
preclinical study or Clinical Study but shall include all resulting data and results reasonably expected to be pertinent to such decision. However, Targacept shall provide each applicable final report to GSK as soon as reasonably practicable
following its receipt or completion by Targacept. 
 4.3 Exercise of Program Options. 
 4.3.1 Option Period/Triggering of Options; HSR and Equivalent. 
 (a) Subject to Sections 4.3.1(b), 6.3 and 13.1, GSK may exercise its Program Option, if any, with respect to any Program only by delivering to Targacept
a written notice of exercise, not later than [********] (as may be extended as provided below pending clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (15 U.S.C. §18a), as amended (“HSR”), and, in any
case, subject to Section 3.7.3) after the applicable PoC Trial Report is provided or made available to GSK (such date, the “Report Date”), specifying the Program (and corresponding Progressed Compounds) as to which the Program
Option is being exercised. The period extending from the Report Date until [********] after the Report Date, or such later date as the Parties may mutually agree, is the “Option Period”; provided that GSK agrees that, if it
determines not to exercise a Program Option prior to expiration of the Option Period, it shall in good faith provide written notice to Targacept promptly upon such determination and the 

					
			
	EXECUTION VERSION	  	-61-	  	

 
date on which any such notice is given shall constitute the last day of the Option Period. GSK shall use reasonable efforts to determine within [********]
following receipt of the PoC Trial Report whether the exercise of any Program Option by GSK requires notifications to be filed by either or both Parties with either or both of the U.S. Federal Trade Commission and the U.S. Department of Justice (or
any U.S. governmental authority which may hereafter have responsibility for such matters) under HSR, or with relevant foreign governmental authorities under any similar foreign law (each, a “Relevant Authority”). If either Party
reasonably determines in good faith, based on advice of counsel, that any such notification is required: (i) the Parties shall (A) reasonably cooperate with each other to coordinate, diligently prepare and file such notifications promptly
after it is determined that such filing(s) is required, provided that all filing, registration or similar fees associated therewith shall be borne by GSK, and (B) use reasonable efforts to respond promptly to any requests for additional
information made by any Relevant Authority and to cause the waiting period (or any extension thereof) under HSR or any similar foreign law to terminate or expire at the earliest possible date after the date of filing; and (ii) the Option Period
shall be extended automatically for [********] from the expiration of the original Option Period (the “Option Period Extension”) in the event that (A) the HSR (or similar foreign law) initial waiting period is still pending or
(B) a “Second Request” was received from a Relevant Authority in connection with such filing during the original Option Period or the then-current Option Period Extension, as the case may be, such Party diligently prepares and
promptly submits a response and clearance has not been granted upon expiration of the original Option Period or the then-current Option Period Extension, as the case may be; provided that GSK agrees that, if it determines not to exercise a Program
Option prior to expiration of the applicable Option Period Extension, it shall in good faith provide written notice to Targacept promptly upon such determination and the date on which any such notice is given shall constitute the last day of the
Option Period Extension. In the event that HSR (or similar foreign law) clearance has still not been granted upon expiration of any Option Period Extension where the date of such expiration is at least [********] from the date of the first such HSR
or similar foreign filing by GSK, then Targacept and GSK shall promptly meet to discuss in good faith whether an additional Option Period Extension is merited. In such event, such additional Option Period Extension shall only be effective with the
[********], not to be [********] can demonstrate a [********], based on documented correspondence from each Relevant Authority, that such HSR (or similar foreign law) clearance is or will more likely than not be forthcoming. In the event that HSR
(or similar foreign law) clearance is not granted upon expiration of the original Option Period or applicable Option Period Extension, as the case may be, such Program Option shall be deemed to have [********]; provided that, in such event and
notwithstanding 

					
			
	EXECUTION VERSION	  	-62-	  	

 
anything to the contrary set forth herein, (i) Targacept’s obligation to pay any Refused Candidate Royalties (or, solely to the extent applicable,
GSK Reverse Royalties) shall only be operative and effective with respect to the [********] in the Program subject to such Program Option if and to the extent such payment would be lawful and (ii) if such payment would not be lawful, Targacept
and GSK shall negotiate in good faith with an objective of [********] to such [********]. 
 (b) Notwithstanding Section 4.3.1(a),
solely upon the mutual written agreement of the Parties (but subject to satisfaction of all HSR or similar foreign law requirements as described in Section 4.3.1(a)), GSK shall have the right to exercise a Program Option prior to the Report
Date (including, for clarity, where a Development Candidate does not become an Option Compound) at any time; provided that the Product Candidate in the Program subject to such early exercise of a Program Option shall be the Leading Compound, which
shall upon such early exercise be deemed to be an Option Compound, and, if applicable, up to two (2) other Progressed Compounds theretofore or thereafter nominated by Targacept as and determined by the JSC to be Backup Compounds or Follow-On
Compounds, as applicable, in accordance with the terms hereof. 
 (c) For clarity, the Parties understand and agree that, except with regard
to the Pain 1 Program under circumstances where (i) TC-2696 becomes an Option Compound, (ii) GSK does not exercise its Program Option and (iii) TC-6499 becomes an Option Compound, and without limiting the applicability of
Section 3.2.3(x), that, for each Program there is one (1) Program Option, regardless of the total number of successful PoC Trials for Progressed Compounds under such Program and regardless of the number of different formulations, methods
of delivery, prodrugs, esters, salts, crystalline polymorphs, hydrates or solvates thereof which are Developed for such Progressed Compounds. It being understood, however, that Targacept shall have no obligation to pursue any such different
formulations, methods of delivery, prodrugs, esters, salts, crystalline polymorphs, hydrates or solvates thereof. 
 4.3.2
Expiration of Program Option; Refused Candidates. If GSK does not exercise its Program Option with respect to a particular Program within the Option Period (or, for clarity, if the Early Development Program Term (or, if none, Research
Program Term) for a particular Program expires without there being an Option Compound), then GSK’s Program Option shall expire with respect to such Program and Targacept shall thereafter have all rights, itself or through or with an Affiliate
or Third Party, to develop and commercialize all Collaboration Compounds in such Program at Targacept’s sole expense, without restriction, and shall also have 

					
			
	EXECUTION VERSION	  	-63-	  	

 
the license from GSK as set forth in Section 5.1.4. Solely with respect to products, including any formulation or dosage or delivery form thereof,
containing or comprising a Refused Candidate (“Refused Candidate Products”), Targacept shall pay to GSK Refused Candidate Royalties as set forth in Section 6.7.1. “Refused Candidates” means the [********] as of
the last day of the Option Period (or, if earlier, the date on which GSK notified Targacept that it would not exercise the Program Option) in each Program for which there is both an Option Period and an unexercised Program Option.

 (a) Without limiting the generality of Section 5.3.2, with
respect to each Option Compound ([********] that achieves [********] based on completion [********] of the equivalent of [********] for [********]), GSK [********] in each case, shall (i) [********] with respect to which the PoC Trial (or
equivalent with respect to [********] that achieves Other Product Candidate 

					
			
	EXECUTION VERSION	  	-69-	  	

 
PoC) had been conducted [********] completion of [********] described in [********] for cause for a [********] as needed in the event that [********] for
needing [********] that would reasonably be expected to [********] and (ii) use its Diligent Efforts [********]; and 
 (b) With respect
to [********] each Licensed Product, in the event that GSK is (i) not using Diligent Efforts to [********] such Licensed Product [********] or (ii) not [********] such Licensed Product [********] where such failure to [********] would
[********] a failure to exercise Diligent Efforts [********] then: (A) all licenses from Targacept to GSK with respect to such Licensed Product [********] shall terminate (as if [********] as applied to such Licensed Product); (B) such
Licensed Product shall be a [********] with respect to [********] and Targacept shall have the same licenses from GSK and the same obligations to GSK with respect to such Licensed Product [********] as Targacept has for [********]; and
(C) Targacept or any Affiliate or licensee thereof shall have [********]. [********] in a manner consistent with [********] for the Licensed Product, to the extent such [********] is (1) [********] or [********], as the case may be
[********] and (2) timely provided to Targacept (collectively, the “[********] Conditions”), until [********] of such [********] is completed [********] (but not longer than [********] from the date [********]); provided that
if: (x) the [********] Conditions apply; (y) after [********] of such [********] Licensed Product is completed in [********], such [********] is commercialized by Targacept or any Affiliate or licensee thereof [********] in a manner that
materially and adversely affects [********]; and (z) GSK provides written notice accompanied by documentary evidence to such effect to Targacept (and, if the commercializing party, any Affiliate or licensee thereof), then Targacept or, if the
commercializing party, any Affiliate or licensee thereof shall, to the extent permitted under applicable law, reasonably promptly (taking into account the then-existing circumstances) modify the manner of its commercialization such that it no longer
has such material adverse effect [********] or [********], as the case may be, or shall forfeit the rights arising under this Section 5.3.3(b) in [********]. For clarity, and without limiting any other provision of this Agreement, any dispute
regarding the application or enforcement of this Section 5.3.3(b) shall be subject to the provisions of Section 14.1. 
 Notwithstanding the foregoing and for the avoidance of doubt, Targacept acknowledges and agrees that in the event it (or its Affiliates or licensee) commercializes a Returned Licensed Product [********] pursuant to this Section 5.3.3,
then, subject to applicable law, Targacept shall, or shall cause its Affiliates or licensee to, sell Returned Licensed Product [********] and shall not 

					
			
	EXECUTION VERSION	  	-70-	  	

 
sell such Returned Licensed Product to any Third Party that Targacept (or its Affiliates or licensee) reasonably believes is going to sell such Returned
Licensed Product, directly or indirectly, [********], unless mutually agreed in writing by the Parties. If Targacept (or its Affiliate or licensee) becomes aware that any of its customers has [********] such Returned Licensed Product [********] or
[********] such Returned Licensed Product [********], or knows or should know that a customer intends to [********] such Returned Licensed Product [********] or [********] such Returned Licensed Product [********], Targacept shall, or shall cause
its Affiliates and licensees to, to the extent permitted under applicable law, use commercially reasonable efforts to cause such customer to cease such [********] activities. 
 5.3.4 Pharmacovigilance. Except as otherwise provided in Section 3.8.2, after GSK exercises its Program Option with respect to any
Program, GSK shall be responsible for maintaining a safety database with respect to the Product Candidates in such Program and reporting all adverse drug reaction experiences related to any such Product Candidate in connection with the activities of
GSK under this Agreement to the applicable Regulatory Authorities in the countries in the Territory in which such Product Candidate is being Developed, in accordance with the laws and regulations of the relevant countries and Regulatory Authorities
and GSK’s internal policies. 
 5.4 Targacept Co-Promotion Rights. 
 5.4.1 Scope and Exercise.  
 (a) Subject to Section 13.1, with respect to each Co-promotion Product, at any time prior to the date that the FDA [********] for such Co-promotion Product, Targacept shall have the option to Co-promote such Co-promotion Product (the
“Co-promotion Right”) for the Pain Indication only to specialists and hospital physicians in the United States [********] (the “Target Professionals”), by providing up to [********] percent ([********]%) (as
determined in good faith by Targacept) of the requisite detailing effort (as determined in good faith by GSK) to the Target Professionals as set forth in the Product Marketing Plan for such Co-promotion Product. The specific terms of
Targacept’s Co-promotion shall be set forth in a definitive Co-promotion agreement, which will incorporate and be consistent with all of the terms and conditions described in this Section 5.4 and include such other reasonable and customary
terms as would be typically be included in a co-promotion agreement governing a similar relationship and shall provide that no breach by Targacept of any Co-promotion Agreement shall be deemed a breach of this Agreement (the “Co-promotion
Agreement”). The Co-promotion Agreement will be drawn up by both Parties in good faith following exercise by 

					
			
	EXECUTION VERSION	  	-71-	  	

 
Targacept of the Co-promotion right with respect to any Co-promotion Product and shall be consistent with the Product Marketing Plan. Targacept’s
Co-promotion right shall be [********] activities to be described in the Co-promotion Agreement, and shall not include [********] GSK shall provide to Targacept for its review and comment the Product Marketing Plan for each Co-promotion Product a
reasonable time prior to execution of the applicable Co-promotion Agreement, which comments it shall consider in good faith, and shall thereafter provide updates at least [********]. GSK will book sales for each Co-promotion Product, manage
distribution and managed care contracting and will [********] for the Co-promotion Product. 
 (b) At least (i) [********] prior to the
launch of a Co-promotion Product for which Targacept has exercised its Co-promotion Right and in any event prior to execution of the applicable Co-promotion Agreement, GSK shall provide Targacept in writing its proposed detail allocation and
geographic responsibilities for such Co-promotion Product and other relevant information sufficient to enable Targacept to understand the actual level of Co-promotion activity it will be required to provide and afford Targacept adequate time to
recruit, evaluate and hire its sales force and have it trained and (ii) [********] prior to the planned launch of such Co-promotion Product, Targacept shall have employed a sufficient number of sales representatives as would reasonably be
expected to be required to fulfill its obligations under the Co-promotion Agreement, or may waive its right to Co-promote the Co-promotion Product. GSK, at its sole expense, will develop and supply all promotional and marketing materials used to
promote the Co-promotion Product in the United States (provided that the quantities of such promotional and marketing materials for each Co-promotion Product shall be allocated to the Parties in proportion to the number of representatives engaged by
each Party to Co-promote such Co-promotion Product), as well as all product-specific training materials and trainers for the training of the Targacept sales representatives (excluding [********] which shall be [********] Targacept). Targacept will
use only GSK-approved promotional messages and materials and will comply with the GSK commercial practices and policies in effect during the Co-promotion period as such are communicated in writing to Targacept. Subject to the preceding sentence,
Targacept’s Co-promotion activities will be conducted in accordance with all applicable laws and regulations (including, without limitation, those promulgated by the FDA and the Division of Drug Marketing and Communications). Targacept shall be
responsible for ensuring that its sales force representatives have comparable levels of knowledge, experience and skills as other sales representatives employed by GSK and 

					
			
	EXECUTION VERSION	  	-72-	  	

 
[********], at the time of such training (in each case, to the extent that GSK provides such information to Targacept in writing). Targacept’s sales
force representatives shall attend, as appropriate in view of GSK’s policies and practices, such training seminars as are held for GSK’s own sales force representatives. Targacept must commit to detailing the applicable Co-promotion
Product in [********] at least for a period of [********] from the date of launch thereof in the United States. Targacept shall not have the right to conduct any of its Co-promotion activities or responsibilities [********]. Subject to
Targacept’s right to provide the level of Co-promotion specified in Section 5.4.1(a) to the Target Professionals, GSK shall not be restricted in its promotional and selling efforts to any specialist, hospital or general practice
physicians, and Targacept shall have no rights to detail or otherwise promote Licensed Products to family practitioners, internal medicine or any other general practice physicians. For clarity, Targacept’s Co-promotion Rights shall apply only
to Co-promotion Products and [********] for the Pain Indication. 
 5.4.2 Sales Force Costs paid by Targacept; [********]
Payments by GSK. Except as provided in Section 5.4.1, Targacept shall be responsible for all costs associated with establishing and maintaining its sales force to conduct such Co-promotion activities. This will include, but not be
limited to, the costs of recruiting, non-product specific training, salaries, and performance incentives or bonuses as appropriate. As the [********] to Targacept for its activities hereunder with regards to Co-promotion, GSK shall pay Targacept
[********] as defined in the Product Marketing Plan [********] at that time and [********] of Targacept’s [********] for the Co-promotion Product. 
 5.4.3 [********]. In no event shall Targacept’s Co-promotion Right or any license granted to Targacept under Section 5.1.5 or under any Co-Promotion Agreement be [********] in any way by
Targacept. 
 5.5 Returned Licensed Products. 
 5.5.1 Termination of Development by GSK. In the event that GSK exercises its Program Option with respect to any Program and thereafter determines in good faith, for any reason, to cease the Development
and commercialization of a Product Candidate or Licensed Product in such Program, either [********] or [********], (i) GSK shall provide Targacept written notice of such intent in accordance with Section 12.3 and shall be deemed to have
terminated all of its rights to such Product Candidate (and any product containing or comprising such Product Candidate) or Licensed Product and (ii) thereupon, such Product Candidate (or 

					
			
	EXECUTION VERSION	  	-73-	  	

 
product containing or comprising such Product Candidate) or Licensed Product shall be deemed a “Returned Licensed Product,” subject to the
provisions of this Section 5.5, and shall no longer be a Licensed Product. 
 5.5.2 Effects of Termination; License to
Targacept. Upon any such termination (a) all licenses in and to the Targacept Technology for such Returned Licensed Product granted to GSK by Targacept, [********], as applicable, shall be immediately terminated (as if [********], in the
case of [********] were [********] as applied to such Licensed Product) and (b) GSK (i) shall promptly return to Targacept all Information (including, without limitation, data and materials) transferred by Targacept to GSK (if GSK’s
rights terminate [********] or, if not, shall cooperate with Targacept in good faith to ensure Targacept’s uninterrupted ability to continue to Develop and commercialize such Returned Licensed Product), (ii) hereby grants to Targacept,
conditional upon the occurrence of such termination, an exclusive license (solely for the purposes set forth below and even as to GSK) [********] or, if applicable, [********] to the GSK Patents (and to GSK’s interest in the Collaboration
Patents, if any), and a non-exclusive worldwide license to the other GSK Technology, with the right to grant sublicenses, in each case that pertains specifically (but not necessarily exclusively) to such Returned Licensed Product and was actually
generated by GSK, or is necessary or reasonably useful, in connection with the Development or commercialization of such Returned Licensed Product, to research, develop, have developed, make, have made, use, import, offer to sell and sell (including,
without limitation, through distributors or wholesalers) such Returned Licensed Product; (iii) shall, if GSK’s rights terminate [********], transfer to Targacept, at no cost (except for any finished product, which shall be transferred at

results, and all other information, regulatory filings, and the like developed by or for the benefit of GSK relating to such Returned Licensed Product, (v) assign to Targacept any regulatory filings or trademarks [********] or, if applicable,
[********] related to such Returned Licensed Product; (vi) only if GSK (and not a Third Party) has manufactured for commercial launch such Returned Licensed Product, supply Targacept with its reasonable requirements for such Returned Licensed
Product (or intermediate thereof) [********] or, if applicable, [********] (which amounts shall be consistent with GSK’s historical usage of each such Returned Licensed Product [********] or, if applicable, [********]) for up to [********]
following such termination at a transfer price equal to GSK’s cost of goods for the supply of such Returned Licensed Product (or intermediate thereof) plus [********] percent ([********]), or, alternatively, in the event that GSK has contracted
with a Third Party manufacturer for its pre-launch or 

					
			
	EXECUTION VERSION	  	-74-	  	

 
commercial supply, promptly after Targacept’s request, assign such supply agreement or reasonably facilitate a new supply agreement between Targacept
and such Third Party manufacturer; (vii) promptly after Targacept’s request, provide to Targacept or its designee all pertinent information in its possession with respect to the manufacture of each such Returned Licensed Product (or
intermediate thereof) as of the effective date of such termination; and (viii) promptly after Targacept’s request, assign to Targacept all agreements between GSK and any Third Party with respect to the conduct of Clinical Studies for such
Returned Licensed Product with respect to [********] or, if applicable, [********], including agreements or contracts with contract research organizations, clinical sites and investigators, unless expressly prohibited by any such agreement (in which
case GSK shall cooperate with Targacept in all reasonable respects to secure the consent of such Third Party to such assignment). Notwithstanding anything to the contrary in this Agreement, the terms and conditions of Section 7.1 shall not
apply to any Returned Licensed Product.

 6.3 Program Option Exercise Fees. 
 6.3.1 For the Pain 1 Program. Upon the exercise of the Program Option by GSK for the Pain 1 Program, GSK shall pay to Targacept a
non-creditable, non-refundable option exercise fee (the “Pain 1 Program Option Exercise Fee”) of (i) [********] Dollars ($[********]), if paid following completion of the PoC Trial for TC-2696, or otherwise (ii) [********]
Dollars ($[********]) within [********] of receipt by GSK of an invoice from Targacept after written notice by GSK to Targacept of exercise of the relevant Program Option. 
 6.3.2 For Other Programs. Upon the exercise of a Program Option by GSK for any Program other than the Pain 1 Program in accordance with

than the Pain 1 Program and Pain 2 Program (for the purposes of this Section, the “Other Four Programs”) all result at the end of the Research Term only in Leads which [********] (the “Credit Outcome”), then
GSK shall automatically have and shall be entitled to apply a credit in the amount of [********] only against the next Program Option Exercise Fee that becomes payable with respect to the Other Four Programs. GSK’s right to this credit shall
expire at such time as any of the Other Four Programs generates a Lead (the “Subject Lead”) which does not [********] as another Lead that is both (i) generated in any other of the Other Four Programs and (ii) not a

 6.4.1 On Milestone Payments- In General. No milestone payments are owed for any Milestone
Event that is not achieved, and each milestone payment shall be payable [********] for each Collaboration Compound or Licensed Product to achieve the corresponding Milestone Event (except for milestones achieved for such Collaboration Compound or
Licensed Product [********] as provided in Section 6.5). In the case where one Progressed Compound, Product Candidate or Licensed Product is substituted for (but not added to) another Progressed Compound, Product Candidate or Licensed Product
for Development or commercialization for the same Indication, then the milestones with respect to the substitute Progressed Compound, Product Candidate or Licensed Product are [********] payable for Milestone Events [********] achieved by such
substitute Progressed Compound, Product Candidate or Licensed Product [********] achieved (and the applicable milestone payment made) with respect to the [********] Progressed Compound, Product Candidate or Licensed Product, except where expressly
provided otherwise in this Agreement (including, without limitation, clause (x) of Section 3.2.3). By way of illustration and without limitation, if (i) a Product Candidate in an Indication has achieved [********] but [********] and
(ii) another Product Candidate for the same Indication achieves [********], the milestone payment [********] payable as a result of the [********] of such other Product Candidate will be deemed to [********]. In addition, no milestone payment
is owed on the basis of the achievement of any Milestone Event with respect to any [********] for the same Collaboration Compound or same Licensed Product if such Milestone Event has already been achieved (and the applicable milestone payment made)
with respect to such Collaboration Compound or Licensed Product; provided however, that multiple milestone payments shall be due with respect to the same Milestone Event if achieved with respect to [********] with respect to the same Collaboration
Compound or Licensed Product if such Milestone Event is achieved with respect to a [********], to the extent such [********] is compensable pursuant to Section 6.5. 
 6.4.2 Determination whether to Pay One-Time [********] Fee. GSK shall notify Targacept in writing of its determination whether to pay the One-Time [********] Fee within [********] following the

an order or decision from which no appeal can be taken or from which no appeal was timely taken, during such [********] year period, (ii) it is [********] (unless such Patent [********] attributable in whole or in part to [********]) or
(iii) it has not been prosecuted in good faith by Targacept (unless GSK has assumed responsibility for Prosecution and Maintenance thereof, if and to the extent permitted under Article 8). The payments representing the remaining [********] that
would otherwise have been payable shall be deposited into a Third Party escrow account to be maintained by GSK on behalf of Targacept (with interest from such account being reinvested into such account). Upon the issuance of a Patent with a Valid
Claim of the type described in Section 6.6.1(a) prior to expiration of [********] years after the date of such First Commercial Sale of such Licensed Product in such country, the remaining [********] (and accrued interest) shall be promptly
paid to Targacept. Thereafter, the full royalty rates set forth in Section 6.6.1(a) shall apply for the remainder of the period for payment applicable under Section 6.6.1(a) as if the previously pending Patent had issued at the time of the
First Commercial Sale in such country. In the event a Valid Claim of the type described in Section 6.6.1(a) does not issue within such [********]-year period, GSK shall retain all such amounts paid into escrow. Notwithstanding the foregoing, in
the event that, and for so long as Generic Incursion exists with respect to such Licensed Product in such country, there shall be a [********] reduction on the escrowed portion and a [********] discount on the non-escrowed portion such that,
together, the escrowed portion and the non-escrowed portion represent a [********] reduction from the rate(s) set forth in Section 6.5 that would otherwise be applicable.

 (c) In the absence of a Valid Claim as described in Section 6.6.1(a) or a pending Patent as
described in Section 6.6.1(b) at the time of the First Commercial Sale in a particular country, but where a Valid Claim of an issued Patent [********] owned or Controlled by Targacept [********] in such country [********] with a claim
[********] such Licensed Product but [********] (but not [********]), then a royalty with respect to Net Sales in such country shall be payable by GSK at rate(s) which are [********] reduced from the rate(s) set forth in Section 6.5 that would
otherwise be applicable and shall be payable for [********] after the date of such First Commercial Sale; provided, however, the obligation to pay any royalty under this Section 6.6.1(c) shall cease immediately and entirely if Generic Incursion
exists with respect to such Licensed Product in such country. 
 (d) If and for so long as none of Section 6.6.1(a), (b) or
(c) applies, but where at the time of the First Commercial Sale in a particular country a Valid Claim of an issued Patent exists which is owned or Controlled by Targacept (solely or jointly with GSK) covering the [********] of such Licensed
Product in such country, then a royalty with respect to Net Sales in such country shall be payable by GSK at rate(s) which are [********] reduced from the rate(s) set forth in Section 6.5 that would otherwise be applicable and shall be payable
until the later of expiration of the last-to-expire Valid Claim or [********] years after such First Commercial Sale, but such reduced rate(s) shall be further reduced by an additional [********] during the period, if any, after expiration of the
last-to-expire Valid Claim as described above but before the end of such [********]-year period. 
 (e) No royalty is payable under
Section 6.6 in the event that none of periods for payment in Sections 6.6.1(a), (b), (c) or (d) apply at the time of sale and in the country of sale for a given Licensed Product. 
 (f) Meaning of Generic Incursion. In the event that, with respect to any particular Licensed Product in any particular country, a Generic Product
is sold in such country, then at the end of the first [********] period during which one or more Third Parties sell a number of units of such Generic Product in such country that is [********] percent ([********]%) or more of the aggregate number of
units of such Licensed Product sold in such country during such period, based upon mutually acceptable Third Party objective data sources, “Generic Incursion” exists.

 (g) Reconciling Reduced Royalty Rate in any Country with Royalty Tiers on Annual Worldwide Net
Sales. In determining the royalty rate(s) payable to Targacept by GSK with respect to Net Sales of a Licensed Product in any country with respect to which a reduction in the otherwise applicable royalty rate(s) applies pursuant to Sections
6.6.1(a), (b), (c) or (d), the distribution of Net Sales of such Licensed Product in such country across each of the applicable royalty tiers set forth in Section 6.5 shall be deemed to be in the same proportion as the distribution of Net
Sales of such Licensed Product in all countries across each of the applicable royalty tiers set forth in Section 6.5. 
 (h) The term
“annual,” as used in this Article 6, shall mean a calendar year running from January 1 (or, with respect to the year in which a Product is first launched, the date of the first Commercial Sale of such Product in the first country in
which a First Commercial Sale occurs) through December 31. 
 (i) In the event there is any disagreement between the Parties under this
Section as to whether any Valid Claim or claim of a pending Patent “covers” any composition of matter, method of use, method of manufacture, etc., the Parties shall attempt to resolve such dispute first in the Joint Patent Committee and
then via a mutually-acceptable Third Party expert using the same process as provided in Section 8.1.3 with respect to inventorship disputes. 
 (j) Acknowledgement. The Parties recognize and acknowledge that each of the following, separately and together, has substantial economic benefit to GSK: (i) Targacept’s expertise concerning the discovery and optimization of
compounds that may become Hits, Leads, Development Candidates, Progressed Compounds and Option Compounds; (ii) the rights granted to GSK arising with respect to the Research Programs and any Early Development Programs; (iii) the disclosure
to GSK of results obtained in the Research Programs and any Early Development Programs by Targacept; (iv) the licenses granted to GSK hereunder, with respect to Targacept Technology that are not within the claims of any Targacept Patents or
Collaboration Patents owned by Targacept, effective upon exercise by GSK of a Program Option; (v) the licenses granted to GSK under Targacept Patents or Collaboration Patents owned by Targacept, effective upon exercise by GSK of a Program
Option; (vi) the restrictions on Targacept pursuant to Section 7.1; and (vii) the exclusivity afforded to GSK by each of the foregoing. The Parties agree that the royalty rates set forth in Section 6.5 and 6.6.1 reflect an
efficient and reasonable blended allocation of the values provided by Targacept to GSK.

 References in this
Section 6.7.2 any year “post first commercial launch” mean a period of 365 consecutive days (or 366 consecutive days in a leap year) beginning on the day of the First Commercial Sale in the first country in which a First Commercial
Sale occurs. 
 6.8 Third Party Intellectual Property. 
 (a) Targacept shall be solely financially responsible for satisfying in full all costs, fees and payments of all types and kinds, 

					
			
	EXECUTION VERSION	  	-85-	  	

 
including, without limitation, upfront payments, annual payments, milestone payments and royalty payments (collectively, “Third Party Intellectual
Property License Fees”) that are or may be owed under one or more licenses from a Third Party for intellectual property (“Third Party Intellectual Property Licenses”) if such licenses (i) are Controlled by Targacept
and existing as of the Effective Date, regardless of the type of intellectual property involved, or (ii) are unanimously identified by the Joint Patent Committee prior to the exercise by GSK of its Program Option for a given Program as being
licenses that are necessary for the successful Development or commercialization of Licensed Products under such Program. 
 (b) GSK shall not
have any obligation whatsoever with respect to any Third Party Intellectual Property License Fees specifically relating to any Third Party Intellectual Property Licenses obtained with respect to sales of Refused Candidate Products or Returned
Licensed Products sold by Targacept, its Affiliates or Sublicensees as permitted hereunder. It is contemplated that any such payments would be made by Targacept directly to the relevant Third Party in accordance with the provisions of the applicable
Third Party Intellectual Property Licenses. 
 (c) Except as described in Section 6.8(a) or (b) or in Section 6.9, to the
extent that after GSK exercises its Program Option for a given Program, either GSK or the Joint Patent Committee identifies other patents, know-how, or other intellectual property owned or Controlled by a Third Party and covering or claiming any
Product Candidate or Licensed Product in such Program or the manufacture or use thereof in the Field, where one or more Third Party Intellectual Property Licenses is reasonably considered by GSK necessary to prevent GSK from infringing such Third
Party’s Patents by the manufacture, use, import or sale of the Product Candidate or Licensed Product in the Field, GSK and Targacept shall (i) cooperate in good faith to negotiate a reasonable Third Party Intellectual Property License with
such Third Party and (ii) [********] such Third Party Intellectual Property License Fees, provided however, that, with respect to any Licensed Product, GSK shall pay all such Third Party Intellectual Property License Fees but shall have the
right to deduct [********] percent ([********]%) [********] of such Third Party Intellectual Property License Fees paid for any Calendar Quarter from the otherwise applicable royalties payable to Targacept for such Calendar Quarter, except that in
no event shall the royalties otherwise payable to Targacept for any Calendar Quarter be reduced by more than [********] percent ([********]%). GSK shall have the right to carry forward and apply any such unused offset or deduction to which GSK is
entitled against royalties payable to Targacept for future Calendar Quarters until the full amount of offset or deduction to which GSK is entitled is fully satisfied.

 6.10 Payments. 
 6.10.1
Commencement of Royalty Payments. Beginning with the Calendar Quarter in which the First Commercial Sale in the first country in which a First Commercial Sale occurs for a Product and for each Calendar Quarter thereafter, royalty payments
shall be made by GSK to Targacept pursuant to Sections 6.5 and 6.6, or by Targacept to GSK pursuant to Section 6.7.1 within [********] following the end of each such Calendar Quarter. Each royalty payment shall be accompanied by a report (the
“Payment Report”), summarizing the total Net Sales on a country-by-country basis of the Licensed Product during such calendar quarter in Dollars and the calculation of royalties due thereon. In addition, the Payment Report shall,
with respect to Net Sales in the United States, Japan and the Major Countries in the EU, include an itemization of the deductions applied to determine such Net Sales. Notwithstanding the foregoing, in the event that no royalties are payable in
respect of a given Calendar Quarter, the Party making the payments (the “Payor”) shall submit a royalty report so indicating. 
 6.10.2 Mode of Payment. All payments under this Agreement shall be payable, in full, in Dollars, regardless of the country(ies) in which sales are made. For the purposes of computing Net Sales of Products sold in a currency
other than Dollars, such currency shall be converted into Dollars as calculated at the actual average rates of exchange for the pertinent quarter or year to date, as the case may be, as used by GSK in producing its quarterly and annual accounts, as
confirmed by GSK’s auditor (or, in the case of Refused Candidate Products and Returned Licensed Products, as used by Targacept in producing its quarterly and annual accounts, as 

					
			
	EXECUTION VERSION	  	-87-	  	

 
confirmed by Targacept’s auditor. All payments owed under this Agreement will be made by wire transfer from either SB or GGL pursuant to wiring
instructions provided in writing from time to time by Targacept to SB, without deduction of exchange, collection or other charges; provided that GGL shall execute the wire transfer for the Upfront Payment and for the purchase of the shares of
Targacept common stock under Section 6.2. 
 All invoices provided to GSK should include Targacept’s bank details, the contact name for issue
resolution and be marked for the attention of GSK’s Project Director), whose name has been provided to Targacept by Licensee. 
 6.10.3 Records Retention. Commencing with the First Commercial Sale of a Licensed Product in the first country in which a First Commercial Sale occurs, the Payor shall keep complete and accurate records for a period of
[********] calendar years after the year in which such sales occurred, such records to be in sufficient detail to permit the Party receiving Royalties (the “Payee”) to confirm the completeness and accuracy of the information
presented in each Payment Report. 
 6.11 Audits. During the Term and for a period of [********] years
thereafter, at the request and expense of the Payee, the Payor shall permit an independent, certified public accountant of nationally recognized standing appointed by the Payee, and reasonably acceptable to the Payor, at reasonable times and upon
reasonable notice, but in no case no more than once per calendar year, to examine such records as may be necessary for the sole purpose of verifying the calculation and reporting of Net Sales and the correctness of any royalty payments made under
this Agreement for any period within the preceding [********] years. Results of any such examination shall be made available to both Payor and Payee. The independent, certified public accountant shall disclose to the Payee only the royalty amounts
which it believes to be due and payable hereunder to the Payee and shall disclose no other information revealed in such audit. Any and all records examined by such independent, certified public accountant shall be deemed the Payor’s
Confidential Information which may not be disclosed by said independent, certified public accountant to any Third Party. If, as a result of any inspection of the books and records of the Payor, it is shown that a Payee’s payments under this
Agreement were less than the amount which should have been paid, then the Payor shall make all payments required to be made to eliminate the discrepancy within [********]. The Payee shall pay for such audit, except that, in the event that the
royalty payments made by the Payor were less than [********] percent ([********]%) of the amounts that should have been paid during the period in question, the Payor shall pay the reasonable costs of the audit.

 6.12 Taxes. 
 6.12.1 Sales or Other Transfers. The recipient of any transfer under this Agreement of Targacept Technology, GSK Technology, Information, Product Candidates, Licensed Products or Returned Licensed
Products, as the case may be, shall be solely responsible for any sales, use, value added, excise or other taxes applicable to such transfer. 
 6.12.2 Withholding. 
 (a) In the event that the Payor is required to withhold any tax in any country regarding any
payment to the Payee due to the laws of such country, the required amount shall be deducted from the payment to be made by the Payor and paid to the applicable taxing authority of such country before any penalty or interest shall attach thereto or
accrue thereon, and the Payor shall promptly notify the Payee of such withholding. Also, in the event such taxing authority routinely provides a tax receipt upon payment, the Payor will procure a tax receipt evidencing payments of such taxes and
forward it to the Payee promptly. Each of Payor and Payee agrees to cooperate with the other in claiming exemptions and rate reductions from such deductions or withholdings under any agreement or treaty from time to time in effect. However, any such
deduction or withholding shall be an expense of and borne solely by the Payee. 
 (b) (i) Targacept hereby warrants that it is a resident
for tax purposes in the United States and that it is entitled to relief from United Kingdom income tax under the terms of the Convention Between the Government of the United States of America and the Government of the United Kingdom of Great Britain
and Northern Ireland for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion With Respect to Taxes on Income and on Capital Gains (the “Treaty”). Targacept shall notify GSK immediately in writing in the event that
Targacept ceases to be entitled to such relief. 
 (ii) GGL hereby warrants that it is a resident for tax purposes in the United Kingdom and
that it is entitled to relief from United States income tax under the terms of the Treaty. GSK shall notify Targacept immediately in writing in the event that the GGL ceases to be entitled to such relief. 
 (c) (i) Pending receipt of formal certification from the UK Inland Revenue, GSK may pay royalty income and any other payments under this Agreement to
Targacept by deducting tax, if required under applicable law, at a rate that does not exceed the rate specified for such specific item of income in the Treaty. Targacept agrees to indemnify and hold harmless GSK against any 

					
			
	EXECUTION VERSION	  	-89-	  	

 
loss, damage, expense or liability arising from a any ultimate and final determination by a UK taxing authority alleging that GSK was not entitled to deduct
withholding tax on such payments at source at a rate specified in the Treaty. 
 (ii) Pending delivery by GSK of the appropriate U.S. form
(currently a Form W-8) to the U.S. Internal Revenue Service, Targacept may to GSK pay royalty income and any other payments under this Agreement, if any, by deducting tax, if required under applicable law, at a rate that does not exceed the rate
specified for such specific item of income in the Treaty. GSK agrees to indemnify and hold harmless Targacept against any loss, damage, expense or liability arising from any ultimate and final determination by a U.S. taxing authority alleging that
Targacept was not entitled to deduct withholding tax on such payments at source at a rate specified in the Treaty. 
 (d) (i) If, as a
result of an assignment by Targacept pursuant to Section 14.3, any payments that are the financial responsibility of GSK to the assignee become subject to U.S. withholding tax, then, as part of claiming a reduced rate of withholding under any
tax treaty to which the United States is a party, the assignee shall sign the appropriate U.S. form prior to any payments being made by GSK, in order for the assignee to secure any applicable reduced treaty rate of withholding. 
 (ii) If, as a result of an assignment by GSK pursuant to Section 14.3, any payments that are the financial responsibility of Targacept to the
assignee become subject to U.S. withholding tax, then, as part of claiming a reduced rate of withholding under any tax treaty to which the United States is a party, the assignee shall sign the appropriate U.S. form prior to any payments being made
by Targacept, in order for the assignee to secure any applicable reduced treaty rate of withholding. 
 (e) (i) If, as a result of an
assignment by Targacept pursuant to Section 14.3, any payments made by the assignee to GSK that are subject to a withholding tax greater than the amount that would have been withheld if an assignment had not been made, then (i) the sum
payable shall be increased as necessary so that after the assignee makes all required deductions or withholdings, GSK receives an amount equal to the sum it would have received had no assignment been made (taking into account any tax credit
available as a result of such excess withholding amount) and (ii) the assignee will make such deductions or withholdings and pay to the applicable taxing authority the full amount deducted or withheld before penalties attach thereto or interest
accrues thereon. In the event such taxing authority routinely provides a tax receipt upon payment, the assignee will procure tax receipts for any such 

					
			
	EXECUTION VERSION	  	-90-	  	

 
withholding evidencing payment of such taxes, which will be forwarded to GSK. The assignee shall assist GSK in claiming exemption from such deductions or
withholdings under any applicable double taxation or similar agreement or treaty. 
 (ii) If, as a result of an assignment by GSK pursuant
to Section 14.3, any payments made by the assignee to Targacept that are subject to a withholding tax greater than the amount that would have been withheld if an assignment had not been made, then (i) the sum payable shall be increased as
necessary so that after the assignee makes all required deductions or withholdings, Targacept receives an amount equal to the sum it would have received had no assignment been made (taking into account any tax credit available as a result of such
excess withholding amount) and (ii) the assignee will make such deductions or withholdings and pay to the applicable taxing authority the full amount deducted or withheld before penalties attach thereto or interest accrues thereon. In the event

 ARTICLE 7

 EXCLUSIVITY 
 7.1 Covenant of Exclusivity Upon Targacept. Subject to Sections 7.2(c) and (d): 
 (a) Indication Exclusivity.
With respect to each of the Indications of Pain, Parkinson’s Disease, Smoking Cessation, Obesity and Addiction, from the Effective Date until the later to occur of (x) the end of the Initial Term or (y) the date that there are no
longer any research, Development or material commercialization activities under this Agreement by either GSK or Targacept with respect to any Collaboration Compounds in the Program that includes such Indication (the “Indication Exclusivity
Period”), Targacept shall work exclusively with GSK (and shall not work independently or for or with any Third Party or provide any license to or for the benefit of any Third Party, in each case other than subcontractors) for the purpose of
the identification, research, optimization, development or commercialization for such Indication of any compounds that derive [********] conducted by Targacept in such Indication in any material respect relevant for drug development from [********]
any NNR Subtype. For clarity, 

					
			
	EXECUTION VERSION	  	-91-	  	

 
neither this Section 7.1(a) nor any other provision hereof shall be deemed to restrict or limit Targacept’s rights (i) to identify, research,
optimize, develop or commercialize any compound that derives [********] conducted by Targacept in [********] (but excluding [********] as a [********]) in any material respect relevant for drug development from [********] any NNR Subtype, either
independently or for or with any Third Party, or (ii) to provide any license to or for the benefit of any Third Party for the purposes set forth in clause (i). It is understood by the Parties that compounds that do not derive [********]
conducted by Targacept in an Indication in any material respect relevant for drug development from [********] an NNR Subtype are not restricted by this Agreement in any way. 
 (b) Protein Target Profile Exclusivity. For each Program, from the start of Research Program activities for such Program until the earlier of
(i) [********] from Effective Date or (ii) the date that the first Lead is identified under such Program (the “PTP Exclusivity Period”), Targacept will be under the obligation to work exclusively with GSK (and not
independently or with or for any Third Party and not to grant any licenses to any Third Party, in each case other than subcontractors) for the purpose of the identification, research, optimization, development or commercialization of any compound
with the same Protein Target Profile (i.e., the [********] that the applicable combination of NNR Subtypes, but irrespective of the manner or degree of [********]) of such Program. 
 (c) MoA Exclusivity. For each Program (other than the Pain 1 Program, for which there shall be no MoA Exclusivity Period), during the MoA
Exclusivity Period, Targacept shall work exclusively with GSK and shall not work independently or for or with any Third Party or provide any license to or for the benefit of a Third Party, in each case other than subcontractors, for the purpose of
the identification, optimization, research, development or commercialization of any compound with the same or substantially the same Mechanism of Action at the applicable Protein Target Profile as any Collaboration Compound (1) selected as
[********] by Targacept or (2) nominated by Targacept as and determined by the JSC to be [********], as applicable. The parties understand that the applicable MoA of a [********] (or [********]) may, by mutual written agreement of the
Parties only, reflect a PTP which differs from the PTP for such Program as of the Effective Date. “MoA Exclusivity Period” means: 
 (1) with respect to any such [********] in a particular Program, the period from the date of identification of such [********] until the earlier of (A) expiration of the Early Development Program Term for such Program or, if
none, the Research Program for such Program or (B) when development of such [********] is terminated; or 

					
			
	EXECUTION VERSION	  	-92-	  	

 (2) with respect to any such [********] in a particular Program, the period from the date of its
determination as such by the JSC following nomination by Targacept until the earliest of: (A) the date on which it is determined whether the [********] has [********]; (B) when development of such [********] is terminated; or (C) if
such [********] becomes a Product Candidate (i.e., upon exercise of the applicable Program Option by GSK), [********] after such [********] reaches(d) the Candidate Selection Stage, unless GSK (or, in the conduct of Targacept Post-Exercise
Activities, Targacept) is then conducting Clinical Trials of such [********], in which case until such time as neither GSK nor Targacept is conducting Clinical Trials of such [********]; provided that, for clarity, a Collaboration Compound
determined to be a [********] prior to [********] that does not continue to qualify as a [********] upon [********] shall, upon [********], cease to have an MoA Exclusivity Period. 
 For clarity, the Parties understand and agree that the obligation of exclusivity upon Targacept during the MoA Exclusivity Period shall apply for any and all potential indications and uses and shall not be limited to
just the Indication that corresponds to the particular Program of [********] in question. 
 (d) Compound Exclusivity. With respect to
each Program, for so long during the Term as any research, development or material commercialization activities (including, without limitation, material promotional activities) are being conducted for any Exclusivity Compound in such Program by
Targacept in such Program’s Research Program or Early Development Program or by GSK (i.e., by GSK after the exercise of a Program Option) in the Product Candidate Commercialization Program (the “Compound Exclusivity Period”),
Targacept hereby covenants that it shall not, either independently or for or with any Third Party (other than subcontractors), research, develop or commercialize any Exclusivity Compound or Related Exclusivity Compound or provide any license to any
Third Party (other than subcontractors) to any Targacept Technology specifically pertaining to any Exclusivity Compound or Related Exclusivity Compound for the purpose of the research, optimization, development or commercialization of any
Exclusivity Compound or Related Exclusivity Compound, in each case other than in the conduct of a Research Program, Early Development Program or, with respect to a Co-promotion Product following the exercise of Co-promotion Right as permitted

and (ii) after the exercise by GSK of its Program Option for such Program, any Product Candidate in such Program or Licensed Product resulting from such Program; provided that in no event shall a Refused Candidate, Refused Candidate Product or
Returned Licensed Product be an Exclusivity Compound. 
 “Related Exclusivity Compound” means, with respect to each
Exclusivity Compound, (i) all Related Compounds which represent any ester, salt, crystalline polymorph, hydrate or solvate of such Exclusivity Compound or that have substantially the same [********] as such Exclusivity Compound [********] such
Exclusivity Compound’s Program and (ii) after the exercise by GSK of its Program Option for such Exclusivity Compound’s Program, all other Collaboration Compounds in such Program (A) for which [********] as of the date of
exercise by GSK of such Program Option, or (B) that first met [********] prior to the date of exercise by GSK of such Program Option and all Related Compounds with respect to the Collaboration Compounds described in clause (ii) above which
represent any ester, salt, crystalline polymorph, hydrate or solvate thereof or that have substantially the same [********] such Collaboration Compounds at the applicable [********]. 
 Notwithstanding the above, in the event (x) GSK terminates a given Program earlier than the end of the Compound Exclusivity Period described above,
other than for an uncured material breach by Targacept, or (y) the Early Development Program Term (or, if none, Research Program Term) for a given Program otherwise expires without the exercise by GSK of its Program Option, the Compound
Exclusivity Period for all Exclusivity Compounds or Related Exclusivity Compounds with respect to such Program shall thereupon terminate. 
 7.2 Covenant of Exclusivity Upon GSK. 
 (a) Limited Non-Compete. Subject to Section 7.2(b), GSK hereby covenants
that, for [********] after the Effective Date, GSK shall not initiate any research, discovery, identification, synthesis, development or commercialization activities with respect to, or designed to identify, any compound that meets the same

 (3) has
[********] as any [********] in any Program subject to [********] and is, at the time of such in-license, [********] that is [********] applicable to such compound(s), if not yet expired, shall terminate. 
 It is understood by the Parties that any compound in-licensed by GSK that does not [********] in any material respect relevant for drug development
[********] does not trigger application of this Section 7.2(d). 
 (e) If pursuant to Sections 7.2(c) or 7.2(d), any GSK internal NNR
activities or the in-license by GSK from a Third Party of any NNR-modulating compound would have the effect of terminating [********] under this Article 7, then GSK’s obligations to Targacept under Section 7.2(a) shall terminate
immediately.

 8.1.3 Inventorship. In case of a dispute in the Joint Patent Committee (or otherwise between Targacept and GSK) over inventorship and, as a result, whether (i) any particular Collaboration Technology is solely owned by
one Party or the other or jointly owned by both Parties or (ii) whether any particular Information is Targacept Know-How, GSK Know-How or Collaboration Know-How, such dispute shall be resolved by patent counsel reasonably acceptable to the
Parties; provided that, with respect to any proposed patent counsel, each Party shall disclose to the other Party any relationship that such Party has or, to its knowledge in good faith, has had with such proposed patent counsel. Expenses of such
patent counsel shall be shared equally by the Parties. 
 8.2 Prosecution and Maintenance of Patents. 
 8.2.1 Patent Filings. The Party responsible for Prosecution and Maintenance of any Collaboration Patents as set forth in Sections 8.2.2 and
8.2.3 shall use commercially reasonable efforts to obtain patent protection for Progressed Compounds and Licensed Products, if and as applicable, using counsel of its own choice but reasonably acceptable to the other Party (provided that GSK
acknowledges and agrees that it has been advised of Targacept’s patent counsel as of the Effective Date and that such patent counsel is reasonably acceptable to GSK), in the Major Countries and such other countries as the responsible Party
shall see fit. 
 8.2.2 Joint Collaboration Patents. The responsibility and strategy for Prosecution and Maintenance of
Collaboration Patents claiming any jointly-owned Collaboration Know-How (“Joint Collaboration Patents”) shall be mutually agreed by GSK and Targacept through the Joint Patent Committee. The Parties shall cooperate through the Joint
Patent Committee to prepare and prosecute patent applications for Joint Collaboration Patents in a manner so as to obtain patent protection for the applicable subject matter, subject to Section 8.2.4. 

					
			
	EXECUTION VERSION	  	-97-	  	

 8.2.3 Solely Owned Collaboration Patents. GSK or Targacept, as the case may be, shall
control the Prosecution and Maintenance of Collaboration Patents claiming any Collaboration Know-How owned solely by such Party in accordance with Section 8.1.2, in each case using counsel of its choice and in such countries as such Party
determines is appropriate, in accordance with and subject to Section 8.2.4 if applicable. 
 8.2.4 Other Matters Pertaining to
Prosecution and Maintenance of Patents. 
 (a) The Parties shall coordinate through the Joint Patent Committee the Prosecution and
Maintenance of (i) Joint Collaboration Patents or (ii) Patents claiming solely owned Collaboration Know-How directed to composition of, or method of making or using, a Progressed Compound that has at least reached the Candidate Selection
Stage or, after exercise by GSK of a Program Option, a Product Candidate or Licensed Product (the Patents in clause (ii), “Compound Patents”); provided that, in the event of any dispute in the Joint Patent Committee regarding the
Prosecution and Maintenance of Joint Collaboration Patents or Compound Patents (other than Compound Patents that are also GSK Patents), Targacept shall have the final say except (A) as to whether generally to Prosecute and Maintain Joint
Collaboration Patents or Compound Patents in a particular country in which GSK agrees to bear all costs for Prosecution and Maintenance and (B) that, subject to Section 8.2.5, GSK shall have the final say after its exercise of a Program
Option with respect to those claims in any such Joint Collaboration Patent or Compound Patent that solely cover the composition of matter of, or method of making or using, a Product Candidate in the Program as to which GSK has exercised its Program
Option. Each Party shall keep the other Party informed as to material developments with respect to the Prosecution and Maintenance of such Joint Collaboration Patents or Compound Patents for which such Party has responsibility for Prosecution and
Maintenance pursuant to Sections 8.2.2, 8.2.3 or 8.2.4(c), including without limitation, by providing copies of any office actions or office action response or other correspondence that such Party provides to or receives from any patent office,
including notice of all interferences, reissues, re-examinations, oppositions or requests for patent term extensions, and by providing the other Party the timely opportunity to have reasonable input into the strategic aspects of such Prosecution and
Maintenance, subject to Section 8.2.5. Without limiting the foregoing, neither Party shall file a new application for such a Joint Collaboration Patent or Compound Patent 

					
			
	EXECUTION VERSION	  	-98-	  	

 
unless it has first disclosed the same to the other Party. Targacept shall have no further obligations under this Section 8.2.4(a) with respect to a
given Patent to the extent such Patent contains only claims covering one or more Refused Candidates, Refused Candidate Products or Returned Licensed Products, except, with respect to a Joint Collaboration Patent, as the Joint Patent Committee may
otherwise determine is necessary to enable either Party to satisfy its legal obligations as a joint inventor. 
 (b) If, during the Term,
the Party responsible for Prosecution and Maintenance of a Joint Collaboration Patent or a Compound Patent (the “Prosecuting Party”) intends to allow such Patent to lapse or become abandoned without having first filed a continuation
or substitution, the Prosecuting Party shall notify the other Party of such intention at least [********] prior to the date upon which such Patent shall lapse or become abandoned, and such other Party shall thereupon have the right, but not the
obligation, to assume responsibility for the Prosecution and Maintenance thereof at its own expense with counsel of its own choice. 
 (c)
Following the exercise by GSK of its Program Option for a Program, if GSK, in good faith, is no longer satisfied with the performance of external counsel used by Targacept with respect to any Compound Patent that claims the composition of, or method
of making or using, a Product Candidate (or Licensed Product) subject to the Program Option so exercised and does not also claim or cover the composition of, or method of making or using, any compound that is not a Related Exclusivity Compound with
respect to such Product Candidate, GSK has the right to assume responsibility for Prosecution and Maintenance of such Compound Patent at GSK’s sole expense using an external law firm mutually and reasonably acceptable to the Parties, subject to
Section 8.2.5. 
 8.2.5 Existing Obligations for Multi-Purpose Patents; Sublicense Agreements. The Parties acknowledge and
agree that: (i) the Patents identified on Schedule 8.2.5 claim or cover subject matter that is subject to [********] while also claiming or covering [********]; (ii) Targacept has licensed certain method of use patents with respect to
TC-2696 under the Sublicense Agreements; and (iii) to the extent of any conflict between (A) the rights of GSK or responsibilities of Targacept hereunder with respect to such Patents (to the extent [********] becomes a Product Candidate),
or any other Patent during the Term that claims or covers subject matter that is subject to [********], and (B) Targacept’s obligations existing as of the Effective Date under [********] or the provisions of the Sublicense Agreements,
[********] the applicable Sublicense Agreement, as the case may be, shall take precedence and control.

 8.3.1 Collaboration Technology. Except as provided in Sections 8.3.3 or 8.2.4(a)(A), each Party shall be responsible for Patent Costs associated with the Prosecution and Maintenance hereunder of any
Collaboration Patents that it owns solely. Targacept and GSK shall [********] the Patent Costs associated with the Prosecution and Maintenance of Joint Collaboration Patents, unless the Parties otherwise agree; provided that either Party may decline
to pay its share of costs for filing, prosecuting and maintaining any Joint Collaboration Patents in a particular country or particular countries, in which case the declining Party shall, and shall cause its Affiliates to, assign to the other Party
(or, if such assignment is not possible, grant a fully-paid exclusive license in) all of their rights, titles and interests in and to such Joint Collaboration Patents. 
 8.3.2 Targacept Patents and GSK Patents. Except as provided in Section 8.3.3 or Section 8.2.4(a)(A), Targacept shall be responsible for [********] percent ([********]%) of the Patent Costs
incurred by Targacept prior to and after the Effective Date in all countries in the Territory with respect to which Patent Costs are incurred with respect to any Targacept Patents. GSK shall be responsible for [********] percent ([********]%) of the
Patent Costs incurred by GSK prior to and after the Effective Date in all countries in the Territory with respect to GSK Patents. 
 8.3.3
Patent Costs Following GSK’s Exercise of Program Option. Notwithstanding Sections 8.3.1 and 8.3.2, following GSK’s exercise of a Program Option, GSK shall be responsible for one hundred percent (100%) of Patent Costs (but
subject to a reasonable reduction in the event that a Patent in question claims subject matter that is licensed to a Third Party) going forward that are associated with the Prosecution and Maintenance of all Targacept Patents and Collaboration
Patents that contain claims covering Product Candidates or Licensed Products subject to the Program Option so exercised. In addition, the Parties, through the Joint Patent Committee, will cooperate to determine if and when any divisional
applications shall be filed with respect to such Targacept Patents and Collaboration Patents. 
 8.4 Defense of Claims Brought by Third
Parties. 
 8.4.1 Collaboration Compounds. If a Third Party initiates an action, suit or proceeding (in any case, a
“Proceeding”) claiming that a patent or other right owned by it is infringed by the manufacture, use, sale or importation of any Collaboration Compound with respect to a Program as to which GSK has not exercised its Program Option
(except for a Refused Candidate or 

					
			
	EXECUTION VERSION	  	-100-	  	

 
Refused Candidate Product, which shall be subject to Section 8.4.3), Targacept shall have the first right, but not the obligation, to defend against
such Proceeding [********]. In the event Targacept elects to defend against such Proceeding, Targacept shall have the sole right to direct the defense and to elect whether to settle such claim. In the event that Targacept elects not to defend
against a particular Proceeding, then it shall so notify GSK in writing within [********] after it first received written notice of the actual initiation of such Proceeding and, during such [********] period, shall take such reasonable measures as
may be necessary to preserve GSK’s legal right to defend against such Proceeding. In such event, GSK shall have the right, but not the obligation, subject to Section 8.2.5, to defend against such Proceeding [********] and thereafter shall
have the right to direct the defense thereof, including, without limitation the right to settle such claim (but only with the consent of Targacept, not to be unreasonably withheld). In any event, the Parties shall reasonably assist one another and
cooperate in any such litigation at the other’s request without expense to the requesting Party. Each Party may at its own expense and with its own counsel join any defense directed by the other Party. Each Party shall provide the other Party
with prompt written notice of the commencement of any such Proceeding, or of any allegation of infringement of which such Party becomes aware, and shall promptly furnish the other Party with a copy of each communication relating to the alleged
infringement that is received by such Party. 
 8.4.2 Licensed Products. If a Third Party initiates a Proceeding claiming that
a patent or other right owned by it is infringed by the manufacture, use, sale or importation of any Product Candidate or Licensed Product (except for a Returned Licensed Product which shall be subject to Section 8.4.3), GSK shall have the
first right, but not the obligation, to defend against any such Proceeding [********]. In the event GSK elects to defend against such Proceeding, GSK shall have the sole right to direct the defense and to elect whether to settle such claim (but only
with the consent of Targacept, not to be unreasonably withheld). In the event that GSK elects not to defend against a particular proceeding, then it shall so notify Targacept in writing within [********] after it first received written notice of the
actual initiation of such Proceeding and, during such sixty-day period, shall take such reasonable measures as may be necessary to preserve Targacept’s legal right to defend against such Proceeding. In such event, Targacept shall have the
right, but not the obligation, to defend against such proceeding [********] and thereafter shall have the sole right to direct the defense thereof, including, without limitation the right to settle such claims. In any event, the Parties shall
reasonably assist one another and cooperate in any such litigation at the other’s request without expense to the requesting Party. Each Party may at its own 

					
			
	EXECUTION VERSION	  	-101-	  	

 
expense and with its own counsel join any defense directed by the other Party. Each Party shall provide the other Party with prompt written notice of the
commencement of any such Proceeding, or of any allegation of infringement of which such Party becomes aware, and shall promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such
Party. 
 8.4.3 Refused Candidates, Refused Candidate Products and Returned Licensed Products. 
 (a) If a Third Party initiates a Proceeding claiming that a patent or other right owned by it is infringed by the manufacture, use, sale or importation
of any Refused Candidate, Refused Candidate Product or Returned Licensed Product, Targacept shall have the sole and exclusive right, but not the obligation, to defend against such Proceeding at its sole cost and expense. GSK shall provide Targacept
with prompt written notice of the commencement of any such Proceeding, or of any allegation of infringement of which GSK becomes aware, and shall promptly furnish Targacept with a copy of each communication relating to the alleged infringement that
is received by GSK. 
 (b) For any Competitive Infringement of a Targacept Patent or a Collaboration Patent with respect to a Refused
Candidate, Refused Candidate Product or Returned Licensed Product, Targacept shall have the sole and exclusive right, but not the obligation, to institute, prosecute, and control a Proceeding with respect thereto (including, without limitation, with
respect to any invalidity or unenforceability defense or counterclaim in connection therewith), by counsel of its own choice and shall be entitled to retain one hundred percent (100%) of any recovery. 
 (c) For any Competitive Infringement of a GSK Patent with respect to a Refused Candidate, Refused Candidate Product or Returned Licensed Product, GSK
shall have the first right, but not the obligation, subject to Section 8.2.5, to institute, prosecute, and control a Proceeding with respect thereto (including, without limitation, with respect to any invalidity or unenforceability defense or
counterclaim in connection therewith) by counsel of its own choice at its own expense, and Targacept shall have the right to be represented in that action by counsel of its own choice at its own expense. If GSK fails to initiate a Proceeding within
a period of [********] after receipt or delivery by it of written notice of such Competitive Infringement pursuant to Section 8.5.1 (subject to a [********] extension to conclude negotiations, if GSK has commenced good faith negotiations with
an alleged infringer for elimination of such Competitive Infringement pursuant to Section 8.5.1 within such [********] period), 

					
			
	EXECUTION VERSION	  	-102-	  	

 
Targacept shall have the right, but not the obligation, to initiate and control a Proceeding by counsel of its own choice, and GSK shall have the right to be
represented in any such action by counsel of its own choice at its own expense. Any damages or other monetary awards recovered shall be shared as follows: (i) the amount of such recovery actually received by the Party controlling such action
shall first be applied to the Parties’ reasonable out-of-pocket costs incurred in connection with such Proceeding (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses); and then (ii) any
remaining proceeds shall be allocated between the Parties [********] percent ([********]%) to Targacept and [********] percent ([********]%) to GSK. Where GSK exercises the first prosecution right set forth in this Section 8.4.3(c), it shall
cooperate in good faith with Targacept or any Third Party to which Targacept has licensed rights to such Refused Candidate, Refused Candidate Product or Returned Licensed Product in all reasonable respects to determine and pursue the most reasonable
method of eliminating the Competitive Infringement (and in responding to an invalidity or unenforceability defense or counterclaim in connection therewith) in view of the parties’ respective interests. 
 8.5 Enforcement of Patents. 
 8.5.1
Duty to Notify of Competitive Infringement. If either Party learns of an infringement, unauthorized use, misappropriation or threatened infringement by a Third Party with respect to any Collaboration Patent, Targacept Patent or, solely
for purposes of Section 8.4.3, GSK Patents, by reason of the manufacture, use or sale of a product identical to or substantially similar to any Collaboration Compound or Product within the Territory (“Competitive
Infringement”), such Party shall promptly notify the other Party and shall provide such other Party with available evidence of such Competitive Infringement. 
 8.5.2 Prior to Exercise of Program Option. For any Competitive Infringement with respect to a Collaboration Compound that occurs prior to GSK’s exercise of its Program Option for the applicable
Program, if at all, Targacept shall have the first right, but not the obligation, to institute, prosecute, and control a Proceeding with respect to any such Competitive Infringement (including, without limitation, with respect to any invalidity or
unenforceability defense or counterclaim in connection therewith), by counsel of its own choice, and GSK shall have the right to be represented in that action by counsel of its own choice at its own expense. If Targacept fails to initiate a
Proceeding within a period of [********] after receipt of written notice of such Competitive Infringement (subject to a [********] extension to conclude negotiations, if Targacept has commenced good faith negotiations with an alleged infringer for
elimination of such Competitive Infringement within such [********] period), then GSK shall have the right, but not the 

					
			
	EXECUTION VERSION	  	-103-	  	

 
obligation, subject to Section 8.2.5, to initiate and control a Proceeding by counsel of its own choice, and Targacept shall have the right to be
represented in any such action by counsel of its own choice at its own expense. Where GSK exercises the right set forth in this Section 8.5.2, it shall cooperate in good faith with Targacept or any Third Party to which Targacept has licensed
Targacept Patents or Collaboration Patents outside of the Field in all reasonable respects to determine and pursue the most reasonable method of eliminating the Competitive Infringement (and in responding to an invalidity or unenforceability defense
or counterclaim in connection therewith) in view of the parties’ respective interests. 
 8.5.3 Following Exercise of Program
Option. For any Competitive Infringement with respect to a Product Candidate or Licensed Product, GSK shall have the first right, but not the obligation, subject to Section 8.2.5, to institute, prosecute, and control a Proceeding with
respect thereto (including, without limitation, with respect to any invalidity or unenforceability defense or counterclaim in connection therewith) by counsel of its own choice at its own expense, and Targacept shall have the right, at its own
expense, to be represented in that action by counsel of its own choice. If GSK fails to initiate a Proceeding within a period of [********] after receipt of written notice of such Competitive Infringement (subject to a [********] extension to
conclude negotiations, if GSK has commenced good faith negotiations with an alleged infringer for elimination of such Competitive Infringement within such [********] period, Targacept shall have the right to initiate and control a Proceeding by
counsel of its own choice, and GSK shall have the right to be represented in any such action by counsel of its own choice at its own expense. Where GSK exercises the right set forth in this Section 8.5.3, it shall cooperate in good faith with
Targacept or any Third Party to which Targacept has licensed Targacept Patents or Collaboration Patents outside of the Field in all reasonable respects to determine and pursue the most reasonable method of eliminating the Competitive Infringement
(and in responding to an invalidity or unenforceability defense or counterclaim in connection therewith) in view of the parties’ respective interests. 
 8.5.4 Share of Recoveries. If one Party initiates a Proceeding in accordance with this Section 8.5, the second Party agrees to be joined as a party plaintiff where necessary and to give the first
Party reasonable assistance and authority to file and prosecute the Proceeding. The costs and expenses of the Party initiating the Proceeding under this Section 8.5 shall be borne by such Party, and any damages or other monetary awards
recovered shall be shared as follows: (i) the amount of such recovery actually received by the Party controlling such action shall first be applied to the Parties’ reasonable out-of-pocket costs incurred in connection with such 

					
			
	EXECUTION VERSION	  	-104-	  	

 
Proceeding (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses); and then (ii) any remaining proceeds
shall be allocated between the Parties (A) if the Competitive Infringement related solely to Product Candidate(s) or Licensed Product(s), such that the Party initiating the Proceeding (as a practical matter, disregarding where a Party is joined
as a plaintiff solely to ensure standing) under this Section 8.5 retains [********] percent ([********]%) and the other Party retains [********] percent ([********]%) of such amount, or (B) if the Competitive Infringement related solely to
Collaboration Compounds that occurred prior to GSK’s exercise of its Program Option for the applicable Program, retained one hundred percent (100%) by Targacept. A settlement or consent judgment or other voluntary final disposition
of a suit under this Section 8.5 may be entered into without the consent of the Party not bringing the suit; provided that such settlement, consent judgment or other disposition does not admit the invalidity or unenforceability of the
relevant Patent, Targacept Technology or GSK Technology and provided further, that any rights granted under the relevant Patent to continue the infringing activity in such settlement, consent judgment or other disposition shall be limited to
those rights that the granting Party otherwise has the right to grant. 
 8.5.5 Other Infringement. Subject to Sections 8.5.1
through 8.5.4 above, with respect to the infringement of a jointly-owned Collaboration Patent which is not a Competitive Infringement, each Party may proceed in such manner as the law permits. Each Party shall bear its own expenses and any recovery
obtained by either Party may be retained by such Party unless otherwise agreed. In addition, Targacept shall retain all rights to pursue an infringement of any Patent solely owned by Targacept which is other than a Competitive Infringement, and GSK
shall retain all rights to pursue an infringement of any Patent solely owned by GSK which is other than a Competitive Infringement. 
 8.5.6 35 USC 271(e)(2) Infringement. Notwithstanding anything to the contrary in this Section 8.5, but subject to Section 8.2.5, for infringement under 35 USC 271(e)(2) where GSK has exercised its Program Option and
is the holder of an NDA for a Product that is the subject of such infringement, and for so long as GSK maintains or retains its exclusive license granted upon exercise of such Program Option, GSK has the sole right to initiate legal action to
enforce all Targacept Patents and Collaboration Patents licensed to it pursuant to Section 5.1.2 against infringement or misappropriation by Third Parties or defend any declaratory judgment action relating thereto at its sole expense.

					
			
	EXECUTION VERSION	  	-105-	  	

 8.5.7 Patent Listing. To the extent required or permitted by law, GSK will use commercially
reasonable efforts to promptly, accurately and completely list, with the applicable Regulatory Authorities during the Term, all applicable Patents for any Licensed Product that GSK intends to, or has begun to commercialize, and that have become the
subject of an NDA submitted to FDA, such listings to include all so-called “Orange Book” listings required under the Hatch-Waxman Act and all so called “Patent Register” listings as required in Canada. Prior to such listings, the
Parties will meet, through the Joint Patent Committee, to evaluate and identify all applicable Patents. Notwithstanding the preceding sentence, GSK will retain final decision making authority as to the listing of all applicable Patents for such
Product, regardless of which Party owns such Patent, subject to Section 8.2.5. 
 8.5.8 CREATE Act. Notwithstanding
anything to the contrary in this Section 8.5, neither Party shall have the right to make an election under the Cooperative Research and Technology Enhancement Act of 2004, 35 U.S.C. 103(c)(2)-(c)(3) (the “CREATE Act”) when
exercising its rights under this Section 8.5 without the prior written consent of the other Party, which shall not be unreasonably withheld, conditioned or delayed. With respect to any such permitted election, the Parties shall use reasonable
efforts to cooperate and coordinate their activities with respect to any submissions, filings or other activities in support thereof. The Parties acknowledge and agree that this Agreement is a “joint research agreement” as defined in the
CREATE Act.

established by the Receiving Party that such Confidential Information: 
 (a) was in the lawful knowledge and possession of the Receiving
Party prior to the time it was disclosed or made available to, or learned by, the Receiving Party, or was otherwise developed independently by the Receiving Party without reference to or use of the Disclosing Party’s Confidential Information,
as evidenced by written records kept in the ordinary course of business or other documentary proof of actual use by the Receiving Party; 
 (b) was available to the public generally or otherwise part of the public domain at the time of its disclosure to the Receiving Party;

containing the objected-to information until the Parties have agreed to the content of the proposed disclosure, (ii) GSK shall delete from the proposed
disclosure any Targacept Confidential Information upon the reasonable request by Targacept and (iii) if Targacept reasonably determines that such abstract, manuscript or presentation contains patentable subject matter, GSK shall delay such
publication for up to an additional [********] to enable Targacept seek appropriate patent protection. Once any such abstract or manuscript is accepted for publication, GSK will provide Targacept with a copy of the final version of the manuscript or
abstract. 
 9.6.3 General. Notwithstanding Sections 9.6.1 and 9.6.2, once an abstract, manuscript or presentation has been
reviewed and approved by a Party, the same content included in such abstract, manuscript or presentation does not have to be provided again to the other Party for review for a later submission for publication. In any permitted publication or
presentation by a Party, the other Party’s contribution shall be duly recognized, and co-authorship shall be determined in accordance with customary standards. Furthermore, with respect to any proposed abstracts, manuscripts or summaries of
presentations by investigators or other Third Parties having the right to do so, such materials shall be subject to review under this Section 9.6 to the extent that GSK or Targacept (as the case may be) has the right to do so.

Losses actually paid by the indemnifying Party in its defense of the Claim with respect to such Indemnitee(s).

Party shall control the defense) or (iii) the named parties to such Claim include both the indemnifying Party and the Indemnitee and the Indemnitee reasonably concludes, based on advice from counsel, that the indemnifying Party and the
Indemnitee have conflicting interests that make separate counsel with respect to such Claim advisable. 
 11.5 Cooperation. The Party
seeking indemnification shall, and shall cause each of its Indemnitees to, (i) cooperate as reasonably requested (at the expense of the indemnifying Party) in the defense of the applicable Claim and (ii) undertake all reasonable steps to

Section 12.2.2 and 12.2.3, in each case and not by this Section 12.2.1, either Party (the “Non-breaching Party”) may, without prejudice to any other remedies available to it at law or in equity, terminate this Agreement,
on a Program-by-Program basis or, if appropriate based on the particular obligation breached and the nature and magnitude of the breach to protect the interest of the Non-breaching Party, in its entirety, in the event (i) the other Party (the
“Breaching Party”) shall have materially breached the performance of any of its material obligations hereunder and (ii) such breach shall have continued for (A) [********] (or, in the case of a payment breach, [********]
or, if such [********] period would expire [********]) after written notice thereof is given to the Breaching Party referencing this Section 12.2.1, describing in reasonable detail the alleged material breach and stating its intention to pursue
a remedy under this Section 12.2.1 if not cured and (B) except in the case of a payment breach, if the Breaching Party has during such [********] period commenced and diligently continued conducting activities designed to cure such breach
but such cure is not possible during such [********] period, the Breaching Party shall have an additional [********] in which to cure the breach. Subject to Section 12.2.3, termination of this Agreement or any Program, as applicable, by the
Non-breaching Party shall become effective on the last day of the applicable cure period if the alleged breach has not been cured. 
 12.2.2 Termination by Targacept due to GSK Diligence Failure Event. In the event that there is a material breach by GSK of (i) its obligation to use its Diligent Efforts to Develop or commercialize a particular Option
Compound or [********] that achieves [********] (but, with respect to [********], only where GSK has [********] with respect to such [********] pursuant to 

					
			
	EXECUTION VERSION	  	-122-	  	

 
Section 5.3.2) as and into a Licensed Product in the Field or (ii) Section 5.3.3(a), Targacept shall have the right to allege a failure of
diligence on the part of GSK (a “GSK Diligence Failure Event”) by written notice to GSK referencing this Section 12.2.2, describing in reasonable detail the alleged GSK Diligence Failure Event and stating its intention to
pursue a remedy under this Section 12.2.2 if not cured; provided that in no event shall any act or failure to act by GSK following receipt of such notice from Targacept constitute an admission or create any implication that a GSK Diligence
Failure Event has in fact occurred. Subject to Section 12.2.3, upon receipt of such notice of a GSK Diligence Failure Event, GSK shall have a period of [********] in which to cure the GSK Diligence Failure Event or, if GSK has during such
[********] period commenced and diligently continued conducting activities designed to cure the GSK Diligence Failure Event but such cure is not possible during such [********] period, GSK shall have an additional [********] in which to cure such
GSK Diligence Failure Event. Upon conclusion of the cure period, as may be extended as described above, if GSK has not cured such GSK Diligence Failure Event, Targacept shall have the right, exercisable not later than [********] after the end of the
cure period, to immediately terminate all licenses hereunder with respect to [********] with respect to which [********] and [********] that had been [********] as [********], in which case Section 12.5.3(b) shall apply. The provisions of this
Section 12.2.2 (and Section 12.5.3(b) and the other provisions referenced in this Section 12.2.2) shall represent the sole and exclusive remedy to Targacept with respect to a GSK Diligence Failure Event. 
 12.2.3 Disagreement. If the Parties in good faith dispute whether there has been a material breach as alleged pursuant to
Section 12.2.1 or whether such material breach has been cured or cured on a timely basis, the Non-breaching Party may contest the allegation in accordance with Section 14.1. Likewise, if GSK in good faith disputes either an alleged GSK
Diligence Failure Event or whether the alleged GSK Diligence Failure Event has been cured or cured on a timely basis, GSK shall have the right to pursue such dispute in accordance with Section 14.1. 
 12.3 Unilateral Termination Rights. GSK shall have the right, at its sole discretion, exercisable at any time during the Term, to terminate this
Agreement (i) in its entirety or (ii) with respect to a particular Program, for any reason or no reason at all, upon ninety (90) days written notice to Targacept referencing this Section 12.3 and stating its intention to
terminate this Agreement or the particular Program, without incurring any additional liability, penalty, cost or expense, other than any costs or expenses which are due and accrued as of the effective date of such termination. Targacept shall have

filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof, or if the other Party shall propose or be a party to any dissolution or liquidation, or if the other Party shall make
an assignment of substantially all of its assets for the benefit of creditors. 
 12.4.2 The Parties intend that all rights and
licenses granted under or pursuant to any section of this Agreement are and shall otherwise be deemed to be for purposes of Section 365(n) of Title 11, United States Code (the “Bankruptcy Code”) licenses of rights to
“intellectual property” as defined in Section 101(35A) of the Bankruptcy Code. The Parties shall retain and may fully exercise all of their respective rights and elections under the Bankruptcy Code. To the extent lawful, upon the
bankruptcy of either Party, the non-bankrupt Party shall further be entitled to a complete duplicate of, or complete access to, any such intellectual property in tangible form, and such, if not already in its possession, shall be promptly delivered

 (e) to require that the Successor must maintain the conduct of each Research Program and each Early Development Program hereunder with at
least the same level of Diligent Efforts as was employed by Targacept, including without limitation, FTE allocation and dedication levels, financial resource dedication and allocation levels, and technical and scientific expert/specialist allocation
and dedication levels, as was employed by Targacept during the [********] prior to such Change of Control, with the uncured failure by the Successor to maintain at least the same levels as described in this paragraph being a material breach of this
Agreement; and

taking into account the total amounts paid to date by GSK under this Agreement to Targacept and the stage of Development of the Program, to obtain for any Program hereunder an “Early In-License,” whereby GSK would exercise such
Program’s Program

the Successor shall pay to GSK an amount equal to [********] the Change of Control Date with respect to [********] the Change of Control Date, in which event: 
 (A) with respect to any Program as to which GSK has exercised its Program Option as of the Change of Control Date, the rights of GSK under Section 5.1.2, solely as apply with respect to the Product Candidates and
Licensed Products in such Program, shall survive;

(x) GSK has not exercised its Program Option and (y) a Research Program Term or Early Development Program Term remains in effect, the Leading Compound and up to [********] (or, in the case of the Pain 1 Program, up to one (1), but only if
the Pain 1 Program includes both TC-2696 and TC-6499 as of the Change of Control Date) other Collaboration Compounds in such Program to be selected [********] by written notice [********] given within [********] after receipt of the payment
described in the paragraph leading in to clause (A) above shall, if not already Progressed Compounds be deemed to be Progressed Compounds and to be Product Candidates and the rights and licenses under Section 5.1.2 that would have been
granted to GSK effective upon exercise of the Program Option for such Program shall thereupon be deemed granted by Targacept or the Successor, as applicable, to GSK and shall survive; provided that, for clarity and notwithstanding the provisions of
Article 6 or Section 12.5.5(b), GSK shall have no financial obligation thereafter to Targacept or the Successor with respect to the further Development or commercialization any such Progressed Compound and Product Candidate; 
 (C) neither Targacept nor the Successor shall have any further obligation to conduct any Research Program or Early Development Program and the Change of

which GSK has paid the milestone for the Milestone Event [********] that has not reached [********], Targacept or the Successor shall, unless notified otherwise in writing by GSK, [********] Research Program for such Program (and the applicable
Research Program Term shall [********]) [********] the Development Candidate Activities for such Leading Compound (such Leading Compound to be subject to clause (B) above); and 
 (D) effective [********] after the Change of Control Date, the Agreement would terminate, subject to the surviving rights and obligations of the Parties
as expressly provided in clauses (A), (B) or (C) above or in Section 12.5.5(b) (including, for clarity but without limitation, the various sections of Article 6 listed therein).

proceeding shall be conducted in accordance with the Commercial Arbitration Rules and Supplementary Procedures for Large Complex Disputes of the AAA and
otherwise as described in this Section 14.1.2. 
 (a) The arbitration shall be conducted by a panel of three (3) persons who shall
have sufficient scientific background and experience in drug development or commercialization, as applicable, to resolve the Unresolved Matter and are independent of both Parties and conflict-free (the “Experts”); provided that the
Parties may instead by mutual agreement select a single independent, conflict-free Expert. Subject to the preceding proviso, within [********] after initiation of arbitration, each Party shall select one person to act as an Expert and the two
Party-selected Experts shall select a third Expert within [********] of their appointment. If the Experts selected by the Parties are unable or fail to agree upon the third Expert, the third Expert shall be appointed by the AAA of Washington D.C. or
New York, New York. The place of arbitration shall be Washington, D.C., and all proceedings and communications shall be in English. 
 (b)
The Expert(s) shall make a final decision with respect to the Unresolved Matter within [********] following the arbitration proceeding; provided that the Expert(s) shall have no authority to award punitive or any other type of damages not measured
by a Party’s compensatory damages. 
 (c) Either Party may apply to the Expert(s) for interim injunctive relief until the arbitration
decision is rendered or the Unresolved Matter is otherwise resolved. Either Party also may, without waiving any right or remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect
the rights or property of that Party pending resolution of the Unresolved Matter pursuant to this Section 14.1.2. Each Party shall bear its own costs and expenses and attorneys’ fees, and the Party that does not prevail in the arbitration
proceeding shall pay the Experts’ fees and any administrative fees of arbitration. 
 (d) Except to the extent necessary to confirm an
award or decision or as may be required by applicable law, regulation or stock exchange rule or listing requirement, neither Party may, and the Parties shall instruct the Expert(s) not to, disclose the existence, content, or results of an
arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the Unresolved Matter would be barred by the applicable
Delaware statute of limitations. 

					
			
	EXECUTION VERSION	  	-135-	  	

 (e) The Parties hereby agree that (i) in the event of an Unresolved Matter involving the alleged
breach of this Agreement (including whether a Party has satisfied its diligence obligations hereunder), neither Party may terminate this Agreement under Article 12 until resolution of the Unresolved Matter pursuant to this Section 14.1.2 and
(ii) any disputed performance or suspended performance pending the resolution of an Unresolved Matter that the Expert(s) determine to be required to be performed by a Party must be completed within a reasonable time period following the final
decision of the Expert(s). 
 (f) The Parties hereby agree that any payment to be made by a Party pursuant to a decision of the Expert(s)
shall be made in Dollars, free of any tax or other deduction. 
 (g) The decision of the Expert(s) shall be the sole, exclusive and binding
remedy between the Parties regarding determination of each Unresolved Matter presented. 
 For the avoidance of doubt, the Parties understand and agree that,
except as provided in the proviso hereinbelow, (x) the dispute resolution process outlined in this Section 14.1 shall not be applicable to any matter for which a Party has final decision-making authority as expressly set forth in Sections
2.3.4(a), 2.3.4(b) or 2.3.5 and (y) the final decision of such Party on such matter shall not be subject to any review under this Section 14.1; provided that, notwithstanding the foregoing, either Party may pursue the dispute resolution
procedures of this Section 14.1 with respect to whether, for any particular matter, such final decision-making authority was exercised in breach of Section 2.3.4(c). 
 14.2 Governing Law. This Agreement and any dispute arising from the performance or breach hereof shall be governed by and construed and enforced
in accordance with the laws of the State of Delaware, U.S.A., without reference to conflicts of laws principles. 
 14.3 Assignment.
Neither this Agreement nor any obligation hereunder shall be assignable by either Party to any Third Party without the prior written consent of the other Party, which shall not be unreasonably withheld, conditioned or delayed. Notwithstanding
the foregoing, either Party may assign this Agreement and the rights, affirmative obligations and interests of such Party, in whole or in part, without any consent of the other Party, to an Affiliate or to a Third Party that acquires all or
substantially all of the business or assets of such Party to which this Agreement pertains (whether by merger, reorganization, acquisition, sale or 

					
			
	EXECUTION VERSION	  	-136-	  	

 
otherwise) and agrees in writing to be bound by the terms and conditions of this Agreement. No assignment shall be valid or effective unless and until the
assignee or transferee shall agree in writing to be bound by the provisions of this Agreement. 
 14.4 Reserved. 
 14.5 Force Majeure. No Party shall be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any
provision of, this Agreement for failure or delay in fulfilling or performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For
purposes of this Agreement, force majeure is defined as causes beyond the reasonable control of the Party, including, without limitation: acts of God; acts, regulations, or laws of any government; war; civil commotion; destruction of
production facilities or materials by fire, flood, earthquake, explosion or storm; labor disturbances; epidemic; and failure of public utilities or common carriers. In such event Targacept or GSK, as the case may be, shall promptly notify the other
Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so
long as it is so disabled for up to a maximum of ninety (90) days, after which time Targacept or GSK, the Party not affected by the force majeure, may terminate this Agreement. To the extent possible, each Party shall use reasonable
efforts to minimize the duration of any force majeure. 
 14.6 Notices. Any notice or request required or permitted to be given
under or in connection with this Agreement shall be deemed to have been sufficiently given if in writing and personally delivered or sent by certified mail (return receipt requested), facsimile transmission (receipt verified), or overnight express
courier service (signature required), prepaid, to the Party for which such notice is intended, at the address set forth for such Party below:

 14.7 Export Clause. Each Party acknowledges that the laws and regulations of the United States
restrict the export and re-export of commodities and technical data of United States origin. Each Party agrees that it will not export or re-export restricted commodities or the technical data of the other party in any form without any appropriate
United States and foreign government licenses. 
 14.8 Waiver. Neither Party may waive or release any of its rights or interests in
this Agreement except in writing. The failure of either Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to
perform any such term or condition. No waiver by either Party of any condition or term in any one or more instances shall be construed as a continuing waiver of such condition or term or of another condition or term. 
 14.9 Severability. If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in
good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties. All other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in
order to carry out the intentions of the Parties as nearly as may be possible. Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction. 
 14.10 Entire Agreement; Amendment. This Agreement, together with the Schedules and Exhibits hereto, and the Stock Purchase Agreement set forth all
the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties with respect to the subject matter hereof and supersede and terminate all prior agreements and understandings, written or oral,
between the Parties with respect to such subject matter. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized representative of each Party.

 14.11 Independent Contractors. Nothing herein shall be construed to create any relationship of employer and employee, agent and
principal, partnership or joint venture between the Parties. Each Party is an independent contractor. Neither Party shall assume, either directly or indirectly, any liability of or for the other Party. Neither Party shall have the authority to bind
or obligate the other Party, and neither Party shall represent that it has such authority. 
 14.12 Headings. Headings used herein are
for convenience only and shall not in any way affect the construction of or be taken into consideration in interpreting this Agreement. 

					
			
	EXECUTION VERSION	  	-139-	  	

 14.13 Books and Records. Any books and records to be maintained under this Agreement by a Party or
its Affiliates or Sublicensees shall be maintained in accordance with U.S. Generally Accepted Accounting Principles in the case of Targacept, and shall be maintained in accordance with International Financial Reporting Standards (IFRS) in the case
of GSK, consistently applied, except that the same need not be audited. 
 14.14 Further Actions. Each Party shall execute,
acknowledge and deliver such further instruments, and do all such other acts, as may be necessary or appropriate in order to carry out the expressly stated purposes and the clear intent of this Agreement. 
 14.15 Parties in Interest. All of the terms and provisions of this Agreement shall be binding upon, and shall inure to the benefit of and be
enforceable by the Parties hereto and their respective successors and permitted assigns. 
 14.16 Construction of Agreement. The terms
and provisions of this Agreement represent the results of negotiations between the Parties and their representatives, each of which has been represented by counsel of its own choosing and neither of which has acted under duress or compulsion,
whether legal, economic or otherwise. Accordingly, each of the Parties hereby waives the application in connection with the interpretation and construction of this Agreement of any rule of law to the effect that ambiguous or conflicting terms or
provisions contained in this Agreement shall be interpreted or construed against the Party whose attorney prepared the Agreement as executed or any earlier draft of this Agreement. In addition, unless the context otherwise requires, the use of the
term “subject to” shall mean “subject always to.” 
 14.17 Supremacy. In the event of any direct conflict between
this Agreement and any Research Plan or Early Development Plan or the Product Candidate Commercialization Program, the terms of this Agreement shall control. 
 14.18 Counterparts. This Agreement may be signed in counterparts, each and every one of which shall be deemed an original, notwithstanding variations in format or file designation which may result from the

 Schedule 1.49 
 Framework 
 These guidelines derive from work published on the
structural properties of known drugs.1,2 The guidelines presented below set forth a method to dissect a compound or molecule for the purpose of assignment
to a series. Compounds defined as a [********] will share a common Framework composed of one or more [********] along with [********], together comprising [********]. The following terms enable the analysis. 
 [********] means [********] in a compound or the [********]. In the event a compound has both, the [********] will be determined from [********], unless [********] are
contained in the [********]. 
 [********] is a [********] for which the following atomic properties are defined: [********]. These properties apply only to
[********]. [********] are not to be included in the [********]. In cases where [********] occur in a [********], it is accepted that [********], all of which may act as [********], would be considered as part of the [********] assuming that the
remainder of [********] does not change. 
 [********] mean [********] within the compound and [********]. For example [********] are all single [********].
[********] will be treated as two separate [********]. 
 [********] is the [********] that contains a key [********], for example [********]. In general,
[********] do not constitute [********], unless they contain one of these [********]. In cases where [********] meet this criteria, the [********] will be determined based on the following rank priority: [********]. 
 [********] are atoms that are [********], with these entities being a relevant component of a [********]. [********] is not considered. 
 [********] are any [********] that are not essential to [********]. 
 [********] is a [********] that is part of a [********]. [********] are considered [********], such that [********] does not result in a [********]. 
 Framework is the guiding principle used to establish into which [********] each compound [********]. A compound’s Framework will be assigned based on application of the following rules, in sequence: 
  

	 	1.	Determine all [********] 

  

	 	2.	Identify all [********]

	 	3.	Identify all [********] 

  

	 	4.	Eliminate all [********] 

  

	 	5.	Specify [********] 

  

	 	6.	Apply [********] to [********] and [********]. 

  

	 	7.	Apply [********] to all other [********]
