	2.4	Disbandment. The JSC shall continue to exist until the first to occur of: (a) the Parties mutually agreeing to disband the JSC; (b) Licensor providing to Denali written notice of its intention to
disband and no longer participate in the JSC; provided, that Licensor shall not give such written notice prior to Fcab Delivery in respect of each Accepted Fcab Target; or (c) the later of (i) Denali ceasing Technical Development
and (ii) Fcab Delivery for the last Accepted Fcab Target to achieve Fcab Delivery (unless otherwise mutually agreed in writing) provided always that the responsibilities of the JSC that continue past such disbandment (including those under
Sections 2.2.6 and 2.2.7) shall be undertaken by the Alliance Managers but otherwise in accordance with this ARTICLE 2. Notwithstanding anything herein to the contrary, upon the first to occur of the foregoing (a), (b) or (c), the JSC
shall be terminated and shall have no further rights or obligations under this Agreement, and thereafter any requirement of either Party to provide Information or other materials to the JSC shall be deemed a requirement to provide such Information
or other materials to the other Party, and any matters requiring agreement shall be subject to the mutual review and agreement of both Denali and Licensor. 

  

	2.5	Location of Meetings. Prior to Fcab Delivery, on an Accepted Fcab Target-by-Accepted Fcab Target basis, the JSC shall meet

	2.6	Conduct of Meetings. The chairperson of the JSC shall be responsible for calling meetings on no less than fifteen (15) Business Days’ notice. Each Party shall make all proposals for agenda items and
shall provide all appropriate information with respect to such proposed items in advance of the applicable meeting as agreed upon by the JSC. An individual designated by the chairperson of the JSC shall prepare and circulate the minutes of each
meeting for review and approval of the Parties within five (5) Business Days after the meeting. The Parties shall agree on the minutes of each meeting promptly, but in no event later than the next meeting of the JSC. 

 

	2.7	Procedural Rules. The JSC shall have the right to adopt such standing rules as shall be necessary for its work, to the extent that such rules are not inconsistent with this Agreement. A quorum of the JSC shall
exist whenever there is present at a meeting at least one (1) representative appointed by each Party. Representation by proxy shall be allowed. The JSC shall take action by consensus of the representatives present at a meeting at which a quorum
exists, with each Party having a single vote irrespective of the number of representatives of such Party in attendance, or by a written resolution signed by at least one (1) representative appointed by each Party. Employees or consultants of
either Party that are not representatives of the Parties on the JSC may attend meetings of the JSC; provided, that such attendees (a) shall not vote or otherwise participate in the decision-making process of the JSC, and (b) are
bound by obligations of confidentiality and non-disclosure that are substantially similar to those set forth in ARTICLE 11.

to by the Senior Officers shall be conclusive and binding on the Parties. If the Senior Officers are not able to agree on the resolution of any such issue within thirty (30) days after such
issue was first referred to them, then (i) [***], (ii) [***]; and (iii) [***]. Disputes arising between the Parties in connection with or relating to this Agreement or any document or instrument delivered in connection herewith, and that are outside
of the jurisdiction of the JSC, shall be resolved pursuant to Section 15.7. Amendments that would vary the resources required from either Party to the Fcab Discovery Plan shall require the mutual written consent of the Parties through
the JSC or the Senior Officers. 

  

	2.9	Limitations on Authority. Each Party shall retain the rights, powers, and discretion granted to it under this Agreement and no such rights, powers, or discretion shall be delegated to or vested in the JSC unless
such delegation or vesting of rights is expressly provided for in this Agreement or the Parties expressly so agree in writing. The JSC does not have the power to amend, modify, or waive compliance with this Agreement, which may only be amended or
modified as provided in Section 15.9 or compliance with which may only be waived as provided in Section 15.11. 

  

	2.10	Alliance Manager. Each Party shall appoint a person(s) who shall oversee contact between the Parties for all matters between meetings of the JSC and shall have such other responsibilities as the Parties may agree
in writing after the Effective Date (each, an “Alliance Manager”). Each Party may replace its Alliance Manager at any time by notice in writing to the other Party. 

 

	2.11	Interactions Between the JSC and Internal Teams. The Parties recognize that each Party possesses an internal structure (including various committees, teams and review boards) that will be involved in
administering such Party’s activities under this Agreement. Nothing contained in this Article shall prevent a Party from making routine day-to-day decisions
relating to the conduct of those activities for which it has a performance or other obligations hereunder, in each case in a manner consistent with the then-current applicable plan and the terms and conditions of this Agreement.

From time to time, the JSC may establish and delegate duties to sub-committees or directed teams (each, a “Working Group”) on an “as-needed” basis to oversee particular projects or activities (for example, joint project team, joint finance group, and/or joint intellectual property group). Each such Working Group shall be constituted
and shall operate as the JSC determines; provided that each Working Group shall have equal representation from each Party, unless otherwise mutually agreed. Working Groups may be established on an ad hoc basis for purposes of a specific project or
on such other basis as the JSC may determine. Each Working Group and its activities shall be subject to the oversight, review and approval of, and shall report to, the JSC. In no event shall the authority of the Working Group exceed that specified
for the JSC. All decisions of a Working Group shall be by consensus. Any disagreement between the designees of Denali and Licensor on a Working Group shall be referred to the JSC for resolution. 

 

	2.13	Expenses. Each Party shall be responsible for all travel and related costs and expenses for its members and other representatives to attend meetings of, and otherwise participate on, the JSC or other Working
Group.

TARGET NOMINATION 
  

	3.1	Selection of Accepted Fcab Targets. Denali has the right to nominate up to three Targets for approval as Accepted Fcab Targets. Prior to the Effective Date, TfR has been accepted by
the Parties as the first such Accepted Fcab Target. Denali may nominate up to two further Accepted Fcab Targets as follows: 

  
 Confidential 

- 37 - 

	 	3.1.1	The second and third Fcab are both to be directed against Targets which have been selected with the aim to facilitate transcytosis of the resulting mAb2 across
the blood-brain barrier. 

  

	 	3.1.2	The second and third Fcab Targets shall be nominated no later than thirty-six (36) months after the Effective Date provided always that if Licensor is requested to
commence work on an Fcab Discovery Plan within [***] of the commencement of work on a prior Fcab Discovery Plan it’s obligation shall be subject to Licensor and/or F-star Ltd having the resources
available to undertake such work. 

  

	 	3.1.3	Denali shall nominate a proposed Accepted Fcab Target by providing a notice to Licensor (an “Fcab Target Nomination Notice”). Such notice must include the Entrez Gene ID,
HUGO or official symbol and common synonyms (if available) for such Target. On receipt of such notice Licensor shall submit the Fcab to the Gatekeeper. Within ten (10) Business Days following the Gatekeeper’s receipt of the Fcab
Target Nomination Notice with respect to a particular Target, the Gatekeeper shall verify whether such Target is on the list of Unavailable Fcab Targets and notify Licensor in writing. On receipt of a response from the Gatekeeper, Licensor shall
notify Denali whether the Proposed Fcab Target is an Available Fcab Target. An Available Fcab Target is a Target in respect of which the Licensor is entitled to exercise the rights set out in the Gamma IP License to nominate as an Accepted Fcab
Target and which is not an Unavailable Fcab Target. The Gatekeeper shall maintain an up-to-date list of Unavailable Fcab Targets (“Unavailable Fcab
Targets”). An Unavailable Fcab Target shall only be a Target that is: 

  

	 	(a)	 the subject of a pre-existing and bona fide internal Fcab program of
Licensor, F-star GmbH, F-star Ltd or their respective Affiliates

on which Licensor, F-star GmbH, F-star Ltd or their respective Affiliates are then expending resources to the
active research, Development or Commercialization of such program and have committed resources to the continued research, Development or Commercialization of such program in the upcoming twelve (12) months, 

 

	 	(b)	under an active, executed written agreement between one or more of Licensor, F-star GmbH, F-star Ltd or their respective Affiliates and a
Third Party that would preclude the grant of a license or exclusivity to such Target, or 

  

	 	(c)	the subject of bona fide, ongoing negotiations between one or more of Licensor, F-star GmbH, F-star Ltd or their respective Affiliates and
a Third Party where such negotiations specifically contemplate that a license or exclusivity would be granted to such Target and a written term sheet (or other written statement (including by email) of the scope and corresponding financial terms of
such potential agreement) has been received or delivered by or to Licensor, F-star GmbH, F-star Ltd or their respective Affiliates. 

 

	 	3.1.4	If the Fcab Target is an Unavailable Fcab Target then, subject to Section 3.1.2, Denali shall be entitled to nominate a different Target as a proposed Accepted Fcab Target and the provisions of this
Section 3.1 shall apply to such proposed Accepted Fcab Target. 

  

	 	3.1.5	 If the Fcab Target is an Available Fcab Target then Licensor shall prepare an Fcab Discovery Plan for such
proposed Accepted Fcab Target and shall submit such plan to Denali. If, based on the Fcab Discovery Plan, Licensor considers that the Fcab Target is not suitable for the generation of Fcabs and

  
 Confidential 

- 39 - 

	 	
mAb2 it shall inform Denali and, the JSC shall meet within thirty (30) days of such Licensor informing Denali to consider the suitability
of such Fcab Target for the generation of Fcabs. If the JSC agrees with Licensor then Denali shall be entitled to nominate a different Target as a proposed Accepted Fcab Target and the provisions of this Section 3.1 shall apply to such
proposed Accepted Fcab Target. 

  

	 	3.1.6	Within thirty (30) days of submission of an Fcab Discovery Plan by Licensor to Denali the JSC shall meet to agree on the Fcab Discovery Plan; and on such agreement, the proposed Accepted Fcab Target shall
become an Accepted Fcab Target. If the Parties are unable to agree upon the terms of the Fcab Discovery Plan, then provided a new Fcab Discovery Plan is substantially similar in scope to the TfR Fcab Discovery Plan (attached hereto as Exhibit 1.51),
requires similar resources from Licensor and the Fcab Delivery Criteria have been agreed by both Parties (such agreement not to be unreasonably withheld or delayed), Licensor shall agree to such new Fcab Discovery Plan. 

 

	3.2	 On an Accepted Fcab
Target-by-Accepted Fcab Target basis, at any point prior to the exercise of the Buy-out Option or, in the event that Denali does
not exercise the Buy-out Option, at any time thereafter, Denali shall be entitled, subject to Section 14.9(c), to have up to eight (8) Fabs as Accepted Fab Targets for each then existing
Accepted Fcab Target. Each nomination shall be specific to the Fcab Target in respect of which it was nominated. For the avoidance of doubt, the eight (8) Accepted Fab Targets shall include any Accepted Fab Target that is the subject of a
License Option. Denali may abandon any Accepted Fab Target (including by reason of written notice by Denali of its decision to terminate the License Option Term pursuant to Section 14.5) by providing written notice identifying such
abandoned Accepted Fab Target to Licensor and Gatekeeper, and such Accepted Fab Target shall cease to be an Accepted Fab Target on receipt of such notice by Licensor. If an Accepted Fab Target ceases to be an

  
 Confidential 

- 40 - 

	 	
Accepted Fab Target, then, subject to Section 14.9(c), Denali would have the right to nominate another Accepted Fab Target with respect to the Accepted Fcab Target but, subject to
Section 14.9(c), in no event shall there be more than eight (8) Accepted Fab Targets for each Accepted Fcab Target at any one time. 

  

	3.3	To select an Accepted Fab Target, Denali shall provide the Gatekeeper with a confidential notice (the “Fab Target Notice”) that shall include: (i) a written description of each Target
proposed for nomination as an Accepted Fab Target; and (ii) a written description of the Accepted Fcab Target in respect of which the Accepted Fab Target is being nominated and in the case of each Target such notice must include the Entrez Gene
ID, HUGO UniProt, SwissProt and other gene/protein listing database and official symbol and common synonyms (if available) for such Target. Within ten (10) Business Days following the Gatekeeper’s receipt of the Fab Target Notice
with respect to a particular Target, the Gatekeeper shall verify whether such Target is on the list of Unavailable Fab Targets and notify Denali in writing (“Gatekeeper Notice”) whether such proposed Target is or is not on the
Unavailable Fab Target list. In addition to the foregoing clearance process, if a proposed Accepted Fab Target is an Incorporated Biologic, then Denali and Licensor shall in good faith discuss and attempt to reach agreement on the scope of the
Target definition with respect to such Incorporated Biologic, taking into account the requirement that exclusivity should be specific to the intended therapeutic approach (analogous to target based exclusivity for Accepted Fab Targets) and ability
of the Gatekeeper to subsequently clear targets submitted by other licensees. If the Parties are unable to agree upon such scope, then the Parties shall resolve the Dispute in accordance with Section 15.7. An “Unavailable Fab
Target” is a Target which is: 

  

	 	(a)	the subject of a pre-existing and bona fide internal program of Licensor, F-star GmbH, F-star Ltd
or their respective Affiliates on which Licensor, F-star GmbH, F-star Ltd or their respective Affiliates are then expending resources to the active research, Development
or Commercialization of such program and have committed resources to the continued research, Development or Commercialization of such program in the upcoming twelve (12) months, 

  
 Confidential 

- 41 - 

	 	(b)	under an active, executed written agreement between one or more of Licensor, F-star GmbH, F-star Ltd or their respective Affiliates and a
Third Party that specifically includes a license grant or exclusivity to such Target, or 

  

	 	(c)	the subject of ongoing bona fide negotiations between one or more of Licensor, F-star GmbH, F-star Ltd or their respective Affiliates and a
Third Party where such negotiations specifically contemplate that a license or exclusivity would be granted to such Target and a written term sheet (or other written statement (including by email) of the scope and corresponding financial terms of
such potential agreement) has been received or delivered by or to Licensor, F-star GmbH, F-star Ltd or their respective Affiliates. 

Notwithstanding the foregoing, prior to the expiration of the Buy-out Option Period, no Fab Target
shall be an Unavailable Fab Target. 
  

	3.4	If the Gatekeeper Notice indicates that the Target is not on the Unavailable Target list, the proposed Target shall automatically be an Accepted Fab Target (“Accepted Fab Target”), and Denali
shall, within thirty (30) days of the Gatekeeper Notice provide to Licensor a preliminary mAb2 Development Plan for the relevant mAb2 and
on receipt of such plan by the Licensor, the Parties will have all rights and obligations hereunder in connection with such Accepted Fab Target (including exclusivity in accordance with ARTICLE 6) as of the date of receipt. If the Gatekeeper
Notice indicates that the proposed Target is on the Unavailable Target list, then Denali shall have the right to nominate an alternative Accepted Fab Target in accordance with Section 3.3. In all cases, Denali acknowledges and agrees
that the first person or entity to submit a Target Notice to the Gatekeeper for such Target will be entitled to be granted rights to such Target.

 ARTICLE 4 

DEVELOPMENT AND REGULATORY 
  

	4.1	Technical Development Activities. Subject to Section 10.1, during the Technical Development Term Denali may conduct the Technical Development activities. Denali shall keep the JSC informed of such
activities and the Parties shall discuss the same at each JSC meeting. Denali shall promptly provide to F-star Ltd a copy (in the form of a glycerol stock) of each Denali Library on its creation. Neither
Licensor, nor F-star Ltd or F-star GmbH shall use any Denali Library to screen or identify Fcabs against any Accepted Fcab Targets. 

 

	4.2	Fcab Discovery Plan. Following agreement of an Fcab Discovery Plan by the JSC in respect of an Accepted Fcab Target Denali shall transfer to Licensor all of the information and materials set out in the relevant
Fcab Discovery Plan. Licensor shall not be obliged to commence any work on the discovery of Fcabs unless and until it has received the materials (including antigen and assays) from Denali as provided for in the Fcab Discovery Plan. On receipt of
such information and materials each Party shall, subject to Section 4.7 and subject to Section 9.2 carry out its responsibilities under the Fcab Discovery Plan. Any disputes related to preparation of or amendment to the Fcab
Discovery Plan shall be handled in accordance with Section 2.8. 

  

	4.3	 Fcab Delivery. Licensor will be providing Fcab sequences to Denali as they are developed
under the Fcab Discovery Plan and the Parties shall collaborate in good faith to identify which sequence is most likely to give the best chance of the Fcab meeting the Fcab Delivery Criteria. When Licensor reasonably considers that it has an Fcab
that will meet the Fcab Delivery Criteria, it shall disclose to Denali the Fcab sequence (the “Proposed Fcab”), and notify Denali that the Fcab sequence is the Proposed Sequence, and shall also disclose the other information
and materials provided for in the Fcab Discovery Plan to Denali. Denali shall have the Fcab Validation Period to review the data and to conduct the Fcab validation experiment(s) set out in the Fcab Discovery

Plan for the Proposed Fcab. For clarity, (a) the Parties anticipate that Licensor will be providing Fcab sequences to Denali as they are developed under the Fcab Discovery Plan and leading
up to the disclosure of the Proposed Fcab, (b) whilst the Parties shall collaborate in good faith to identify which sequence is most likely to give the best chance of the Fcab meeting the Fcab Delivery Criteria, [***], (c) all validation
experiment(s) carried out for the purposes of this Section 4.3 and 9.11 shall be carried out in accordance with the protocol agreed by the JSC and (d) Denali is only obligated to conduct such Fcab validation experiment(s) [***] for
an Fcab provided by Licensor for each Accepted Fcab Target, except that Denali will conduct [***] additional validation experiment(s) in accordance with Section 9.11. As soon as reasonably possible after completion of the validation
experiment(s), Denali shall inform Licensor: 

  

	 	4.3.1	that it agrees with Licensor that the Fcab Delivery Criteria have been sufficiently met then “Fcab Delivery” shall be deemed to have occurred on the date that Denali has made such
determination after analysing the results of the validation experiment(s); or 

  

	 	4.3.2	that it disagrees with Licensor that the Fcab Delivery Criteria have been sufficiently met, in which case it shall identify in what respect the Fcab Delivery Criteria have not been sufficiently met. Promptly on
such occurrence the JSC shall meet to determine what (if any) further work is necessary to achieve the Fcab Delivery Criteria. The Parties may agree to amend the Fcab Discovery Plan for such Fcab. Notwithstanding the foregoing Denali may decide to
declare that Fcab Delivery has occurred even if not all of the Fcab Delivery Criteria have been met. 

  

	4.4	 In the event that Licensor and Denali cannot agree that the Fcab Delivery Criteria have been met then the
relevant Fcabs shall be provided to an independent laboratory agreed by both Parties and the relevant laboratory shall undertake the Fcab validation experiment(s) provided for in the Fcab Discovery Plan. The conclusions of the

such date. [***] shall pay the costs of such independent laboratory’s conduct of such Fcab validation experiment(s). 

  

	4.5	In the event that Denali does not respond within the Fcab Validation Period provided for in Section 4.3 the Fcab Delivery shall be deemed to have taken place. 

 

	4.6	On Fcab Delivery or delivery of a Denali Fcab Notice in respect of a particular Fcab Denali shall prepare and deliver to Licensor the preliminary mAb2
Development Plans for the research and development of each mAb2 that Denali intends to generate in respect of such Fcab. Thereafter, during the License Option Term, Denali shall prepare and
deliver to Licensor, at least once in every [***], updated mAb2 Development Plans. The content of such mAb2 Development Plans shall be in
Denali’s sole discretion and Licensor shall, subject to agreement of the activities in the relevant mAb2 Development Plan, provide technical support provided always that Licensor shall not be
obligated to expend any resources or incur any costs in excess of [***] FTEs in each Calendar Year across all mAb2 Development Plans, without Licensor’s prior written consent, which consent
shall be in its sole discretion. Each mAb2 Development Plan shall be the Denali Program Know-How. 

 

	4.7	Diligence. 

  

	 	4.7.1	Licensor shall use its Commercially Reasonable Efforts to carry out the Fcab Discovery Plan. Licensor shall provide Denali with [***] reports detailing the progress of its activities under Fcab Discovery Plan.

	 	4.7.3	The Parties acknowledge and agree that no outcome or success is or can be assured and that failure to achieve desired results will not in and of itself constitute a breach or default of any obligation in this
Agreement. 

  

	4.8	Technology transfer. Following Fcab Delivery of the first Fcab for each Accepted Fcab Target Licensor shall and shall procure that F-star GmbH and F-star Ltd shall, (to the extent any such Person Controls any such Information), make available to Denali any Information and materials specifically identified in the relevant Fcab Discovery Plan not already
provided. 

  

	4.9	Diligence. Denali shall use its Commercially Reasonable Efforts to carry out each mAb2 Development Plan. Denali shall provide an update on progress for
each mAb2 Development Plan at each JSC meeting and each Alliance Managers meeting under Section 2.5. The Parties acknowledge and agree that no outcome or success is or can be assured
and that failure to achieve desired results will not in and of itself constitute a breach or default of any obligation in this Agreement. 

  

	4.10	Subcontracting. Licensor shall not subcontract its obligations under a Fcab Discovery Plan or a mAb2 Development Plan, except to Approved Subcontractors and
Affiliates that have agreed in writing to be subject to the applicable terms and conditions of this Agreement, including the requirements under Section 4.7.1 and Section 4.7.2, the confidentiality provisions of ARTICLE

Such
records shall be retained by each Party and its Affiliates and Approved Subcontractors for at least [***] after the expiration or termination of this Agreement, or for such longer period as may be required by Applicable Law. Upon request, Licensor

	9.10	Royalties. As further consideration for the rights granted to Denali hereunder, subject to Section 9.10.2, commencing upon the First Commercial Sale of a Licensed Product in the Territory, on a
Licensed Product-by-Licensed Product basis, Denali shall pay to Licensor a royalty on Net Sales of each Licensed Product during the Royalty Term in the Territory
(excluding Net Sales of each Licensed Product in any country or other jurisdiction in the Territory for which the Royalty Term for such Licensed Product in such country or other jurisdiction has expired) during each Calendar Year at the following
rates:

	 	9.10.2	Reductions. In the event that, for the purpose of Exploiting a mAb2 or Licensed Product, Denali reasonably decides after good faith consultation with
patent counsel that the Exploitation of a mAb2 or a Licensed Product is likely to infringe one or more of the Patents falling within clauses (a) or (b) below which are owned by a Third Party,
and if Denali obtains a License under any such Patents owned by a Third Party that: 

  

	 	(a)	has specific claims which would be infringed by or prevent the practising of the inventions specifically as claimed in [***]; or 

  

	 	(b)	specifically claims or covers the sequences of the binding loops of the Fcab portion of the relevant mAb2 or claims or covers the use of such binding loops;

 then Denali shall be entitled to deduct [***] of the amount of royalties actually paid by Denali to such Third Party from
the royalties paid to Licensor in respect of that mAb2 only in any given Calendar Quarter pursuant to Section 9.10, provided always that nothing in this Section 9.10.2
shall operate to reduce the amount of Royalties otherwise payable to Licensor in respect of that mAb2 to less than fifty percent (50%) of the Royalties provided for in Section 9.10.

  

	 	9.10.3	 Generic Competition. In the event that, in respect of a given mAb2, on a country by country basis a Third Party has obtained Regulatory Approval for and launches an Antibody which comprises (i) a binding region of a constant domain that binds to the Accepted
Fcab Target, and the making, using, selling, offering for sale or importation of such binding region or constant domain either (a) where such Patents Rights in such country covering such mAb2
have expired or been held invalid, infringed a Valid Claim of one or more of the Licensor Background Patents, Licensor

Program Patents, Platform Patents, Denali Program Patents or Joint Program Patents in that country, or (b) where there were no such Patents in such country covering such mAb2, would have infringed a Valid Claim of one or more of the Licensor Background Patents, Licensor Program Patents, Platform Patents, Denali Program Patents or Joint Program Patents in the U.S. if such
mAb2 was made, used, sold, offered for sale or imported into the U.S.; and (ii) a Fab that binds to the Accepted Fab Target (or in the case of a Incorporated Biologic, a Fab that incorporates
the Accepted Fab Target) of the relevant mAb2, and all of the Licensor Background Patents, Licensor Program Patents, Platform Patents, Denali Program Patents and Joint Program Patents in such
country which covered or claimed the relevant mAb2 or the Fcab that comprises part of such mAb2 have expired or are held invalid (or there were
no such Patents issued in such country); then the royalty rate on the relevant mAb2 (a) shall be reduced [***] if the binding region of such Third Party Antibody comprises binding loops with the
same amino acid sequence as the binding loops in the Fcab of the relevant mAb2, or (b) shall be reduced [***] if the binding region of such Third Party Antibody comprises binding loops with a
different amino acid sequence than the binding loops in the Fcab of the relevant mAb2. 

  

	9.11	 Denali Fcab Payment Reductions. In the event that for a given Accepted Fcab Target,
(i) the Proposed Fcab provided by the Licensor to Denali fails to meet the Fcab Delivery Criteria for that Accepted Fcab Target (or Licensor was otherwise unable to provide to Denali a Proposed Fcab during the [***] period after Denali has
transferred to F-star all reagents and assays for F-star to conduct the antigen validation (e.g. conclusion of Step 1, Antigens of Schedule 1.51 for the TfR Fcab
Discovery Plan) under the applicable Fcab Discovery Plan); (ii) Denali has provided to Licensor the Denali Fcab Notice with respect to a Denali Fcab for such Accepted Fcab Target; and (iii) Licensor does not provide to Denali an Fcab against

Denali provides to Licensor the Denali Fcab Notice (the “Fcab Disclosure Period”); then all of the payments set out in Sections 7.3, 9.6, 9.7, 9.8, 9.9 and 9.10 in respect of the relevant
Fcab and any such payment in respect of a mAb2 incorporating such Fcab shall be reduced by [***] such that the amount payable is [***] of the amount set out in those sections. If the Proposed Fcab
for an Accepted Fcab Target failed to meet the Fcab Delivery Criteria, and Licensor subsequently provides to Denali during the Fcab Disclosure Period another Licensor Fcab for validation testing, then Denali shall only be obligated to conduct [***]
additional validation experiment(s) for such additional Licensor Fcab, and if such additional Licensor Fcab does not meet the Fcab Delivery Criteria, then Licensor shall be responsible to reimburse Denali for its costs to conduct such additional
validation experiment(s) in respect of [***] Licensor Fcab only). In addition, Licensor shall be entitled (but not obliged) to conduct, at its own cost, [***] validation experiment(s) for [***] Licensor Fcab in addition to the [***] Licensor Fcabs
that are subject to the validation experiments carried out by Denali, provided such validation experiment(s) is carried out within the Fcab Disclosure Period. The above reduction shall not apply: 

 

	 	9.11.1	if Licensor delivers the sequence of an Fcab against such Accepted Fcab Target which within such period meets or subsequently is found to meet the Fcab Delivery Criteria prior to expiration of the Fcab Disclosure
Period for such Accepted Fcab Target, and, upon the date of Fcab Delivery of such an Fcab, Denali shall pay the difference between the amounts that were paid in respect of the Denali Fcab and the amounts that would have been paid if Denali had
selected a Licensor Fcab;

	 	9.11.2	if, notwithstanding that the Fcab against such Accepted Fcab Target delivered by Licensor did not meet the relevant Fcab Delivery Criteria, Denali nevertheless selects a Licensor Fcab or Joint Fcab for the
development of mAb2 as evidenced by initiation of GMP manufacture for a Licensed Product that incorporates such Licensor Fcab or Joint Fcab; or 

 

	 	9.11.3	in respect of any mAb2 which contains a Licensor Fcab or a Joint Fcab. 

  

	9.12	Royalty Payments and Reports. Denali shall calculate all amounts payable to Licensor pursuant to Section 9.10 at the end of each Calendar Quarter, which amounts shall be converted to Dollars, in
accordance with Section 9.13. Denali shall pay to Licensor the royalty amounts due with respect to a given Calendar Quarter within forty five (45) days after the end of such Calendar Quarter and each such payment once made shall be non-refundable except as expressly provided in Section 9.17. Each payment of royalties due to Licensor shall be accompanied by a statement of the amount of Net Sales of each Licensed Product in each
country or other jurisdiction in the Territory during the applicable Calendar Quarter (including such amounts expressed in local currency and as converted to Dollars), the applicable royalty rate(s) under this Agreement (including any reduction(s)
to such royalty rate(s) under Section 9.10.2) and a calculation of the amount of royalty payment due on such Net Sales for such Calendar Quarter. 

  

	9.13	Mode of Payment. All payments to either Party under this Agreement shall be made from the US to the UK, without setoff, by deposit of Dollars in the requisite amount to such bank account as Licensor may from time
to time designate by notice to Denali. For the purpose of calculating any sums due under, or otherwise reimbursable pursuant to, this Agreement (including the calculation of Net Sales expressed in currencies other than Dollars), a Party shall
convert any amount expressed in a foreign currency into Dollar equivalents using its, its Affiliate’s or Sublicensee’s standard conversion methodology consistent with Accounting Standards.

	9.14	Withholding Taxes. When a Party becomes aware that it will have an obligation to deduct or withhold an amount for or on account of tax from any payment under this Agreement it shall notify the Party who is
entitled to receive the payment in writing as soon as reasonably practicable and the Parties shall use their reasonable endeavours to do all such acts and things and to sign all such documents as will enable them to take advantage of any applicable
double taxation agreement, treaty or domestic exemption which may apply to eliminate or reduce withholding taxes and otherwise provide the other Party such assistance as is reasonably required to obtain a refund of the withheld or similar taxes, or
obtain a credit with respect to such taxes. In the event there is no applicable double taxation agreement, treaty or domestic exemption, or if an applicable double taxation agreement, treaty or domestic exemption reduces but does not eliminate such
withholding or similar tax, the payor shall deduct the amount paid from the amount due to the payee, remit such withholding or similar tax to the appropriate tax authority and secure and send to the payee reasonable evidence of the payment of such
withholding or similar tax. In the event that any taxes (including without limitation any stamp duties or stamp duty reserve taxes) are required by applicable tax law to be withheld or deducted for or on account of tax from any payments made under
this Agreement, any taxes so withheld and deducted from any payment by the payor and paid over to the appropriate government tax authority shall be treated as paid to the payee under this Agreement. 

 

	9.15	 Indirect Taxes. All payments are exclusive of value added taxes, sales taxes, consumption taxes and other
similar taxes (the “Indirect Taxes”). If any Indirect Taxes are chargeable in respect of any payments, the paying Party shall pay such Indirect Taxes at the applicable rate in respect of such payments following receipt, where
applicable, of an Indirect Taxes invoice in the appropriate form issued by the receiving Party in respect of those payments. The Parties shall issue invoices for all amounts payable under this Agreement consistent with Indirect Tax requirements and
irrespective of whether the sums may be netted for settlement purposes. If the Indirect

Taxes originally paid or otherwise borne by the paying Party are in whole or in part subsequently determined not to have been chargeable, all necessary steps will be taken by the receiving Party
to receive a refund of these undue Indirect Taxes from the applicable governmental authority or other fiscal authority and any amount of undue Indirect Taxes repaid by such authority to the receiving Party will be transferred to the paying Party
within forty-five (45) days of receipt. 

  

	9.16	Financial Records. Denali shall, and shall cause its Sublicensees and Affiliates to, keep complete and accurate books and records pertaining to Net Sales of Licensed Products in sufficient detail to calculate all
amounts payable hereunder and to verify compliance with its obligations under this Agreement. Such books and records shall be retained by Denali and its Sublicensees and Affiliates until [***] after the end of the Calendar Year to which such books
and records pertain. 

  

	9.17	 Audit. At the request of Licensor, Denali shall, and shall cause its Sublicensees and Affiliates
to, permit an independent public accounting firm of nationally recognized standing designated by Licensor and reasonably acceptable to Denali, at reasonable times during normal business hours and upon reasonable notice, to audit the books and
records maintained pursuant to Section 9.16 to ensure the accuracy of all payment reports and payments made hereunder. Such examinations may not (a) be conducted for any Calendar Quarter more than [***] after the end of such
Calendar Year to which such books and records pertain, (b) be conducted more than once in any twelve (12) month period (unless a previous audit during such twelve (12)-month period revealed an underpayment with respect to such period) or
(c) be repeated for any Calendar Quarter. The accounting firm shall report to the Parties with reasons whether the reports are correct or not, and the specific details concerning any discrepancies. No other information shall be shared with
Licensor. Except as provided below, the cost of this audit shall be borne by the auditing Party, unless the audit reveals a variance of more than [***] from the reported amounts, in which case the audited Party shall bear the cost of the audit.
Unless disputed pursuant to Section 9.18 below, if such audit

by the audited Party, the auditing Party shall reimburse such excess payments, in either case ((i) or (ii)), within sixty (60) days after the date on which such audit is completed by the auditing Party. The accounting firm shall provide to
Denali a preliminary copy of its audit report, and shall discuss with Denali any issues or discrepancies that Denali identifies, prior to submission to Licensor. 

  

	9.18	Audit Dispute. In the event of a dispute with respect to any audit under Section 9.17, Licensor and Denali shall work in good faith to resolve the disagreement. If the Parties are unable to reach a
mutually acceptable resolution of any such dispute within thirty (30) days, the dispute shall be submitted for resolution to a certified public accounting firm jointly selected by each Party’s certified public accountants or to such other
Person as the Parties shall mutually agree (the “Audit Arbitrator”). The decision of the Audit Arbitrator shall be final and the costs of such arbitration as well as the initial audit shall be borne between the Parties in such
manner as the Audit Arbitrator shall determine. Not later than thirty (30) days after such decision and in accordance with such decision, the audited Party shall pay the additional amounts, or the auditing Party shall reimburse the excess
payments, as applicable. 

  

	9.19	Confidentiality. The receiving Party shall treat all information subject to review under this ARTICLE 9 in accordance with the confidentiality provisions of ARTICLE 11 and the Parties shall cause

	 	(e)	on an Accepted Fcab Target-by-Accepted Fcab Target basis, the infringement by Licensor of any Third Party Patents or Know-How relating to the Accepted Fcab Target, solely to the extent (i) such infringement arose from Licensor’s conduct of the applicable Fcab Discovery Plan (and not any subsequent research, development
or commercialization of a Fcab to such Accepted Fcab Target by Licensor or any product incorporating any such Fcab), and (ii) Denali knew of such Third Party Patents or Know-How at the time of preparing

 except for those Losses for which Licensor, in whole or in part, has an obligation to
indemnify Denali pursuant to Section 13.2 hereof, as to which Losses each Party shall indemnify the other to the extent of their respective liability for such Losses. 

 

	13.2	Indemnification of Denali. Licensor shall indemnify Denali, its Affiliates and its and their respective directors, officers, employees, and agents (the “Denali Indemnitees”), and defend

 except for those Losses for which Denali has an obligation to indemnify Licensor pursuant to Section 13.1
hereof, as to which Losses each Party shall indemnify the other to the extent of their respective liability for the Losses. 
  

	13.3	Notice of Claim. All indemnification claims in respect of a Party, F-star Ltd, F-star GmbH, and its and their respective Affiliates,
or their respective directors, officers, employees and agents shall be made solely by such Party to this Agreement (the “Indemnified Party”). The Indemnified Party shall give the indemnifying Party prompt written notice (an
“Indemnification Claim Notice”) of any Losses or discovery of fact upon which such Indemnified Party intends to base a request for indemnification under this ARTICLE 13, but in no event shall the indemnifying
Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such
Loss is known at such time). The Indemnified Party shall furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims. 

 

	13.4	Control of Defense. 

  

	 	13.4.1	 In General. Subject to the provisions of Section 10.4, at its option, the indemnifying
Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within thirty (30) days after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a
Third Party Claim by the indemnifying Party shall not be construed as an acknowledgment that the indemnifying Party is 

  
 Confidential 

- 106 - 

	 	
liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified
Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party which shall be
reasonably acceptable to the Indemnified Party. In the event the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the indemnifying Party all original notices and documents (including
court papers) received by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in Section 13.4.2, the indemnifying Party shall not be
liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim unless specifically requested in writing by the indemnifying
Party. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the Indemnified Party from and against the Third Party Claim, the Indemnified Party shall reimburse the
indemnifying Party for any Losses incurred by the indemnifying Party in its defense of the Third Party Claim. 

  

	 	13.4.2	Right to Participate in Defense. Without limiting Section 13.4.1, any Indemnified Party shall be entitled to participate in, but not control, the defense of such Third Party Claim and to
employ counsel of its choice for such purpose; provided, that such employment shall be at the Indemnified Party’s own expense unless (a) the employment thereof, and the assumption by the indemnifying Party of such expense, has been
specifically authorized by the indemnifying Party in writing, (b) the indemnifying Party has failed 

  
 Confidential 

- 107 - 

	 	
to assume the defense and employ counsel in accordance with Section 13.4.1 (in which case the Indemnified Party shall control the defense), or (c) the interests of the
Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under Applicable Law, ethical rules or equitable principles.

  

	 	13.4.3	Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that shall not result in the Indemnified Party’s becoming subject to
injunctive or other relief or otherwise adversely affecting the business of the Indemnified Party in any manner, and as to which the indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder,
the indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, shall deem appropriate. With
respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 13.4.1, the indemnifying Party shall have authority to consent to
the entry of any judgment, enter into any settlement or otherwise dispose of such Loss; provided, that it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed).
If the indemnifying Party does not assume and conduct the defense of a Third Party Claim as provided above, the Indemnified Party may defend against such Third Party Claim. Regardless of whether the indemnifying Party chooses to defend or prosecute
any Third Party Claim, no Indemnified Party shall admit any liability with respect to, or settle, compromise or dispose of, any Third Party Claim without the prior written consent of the indemnifying Party, which consent shall not to be unreasonably
withheld, conditioned or delayed. The indemnifying Party shall not be liable for any settlement, compromise or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the indemnifying Party, which consent
shall not be unreasonably withheld, conditioned or delayed. 

  
 Confidential 

- 108 - 

	 	13.4.4	Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall, and shall cause each indemnitee to, cooperate in the defense or
prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such
cooperation shall include access during normal business hours afforded to the indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making
Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party shall reimburse the Indemnified Party for
all its reasonable out-of-pocket expenses in connection therewith. 

  

	 	13.4.5	Expenses. Except as provided above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any Third Party Claim shall
be reimbursed on a Calendar Quarter basis in arrears by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the
indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

THE TERMS OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE USE OF THE LICENSED COMPOUND OR LICENSED PRODUCT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. 

 

	 	13.4.7	Insurance. Each Party shall obtain and carry in full force and effect the minimum insurance requirements set forth herein. The types of insurance, and minimum limits shall be: General Liability Insurance
with a minimum limit of One Million Dollars ($1,000,000) per occurrence and Two Million Dollars ($2,000,000) in the aggregate. General Liability Insurance shall include, at a minimum, beginning at least thirty (30) days prior to First
Commercial Sale of a Licensed Product, product liability insurance. 

  

	 	13.4.8	Certificates of Insurance. Upon request by a Party, the other Party shall provide Certificates of Insurance evidencing compliance with this Section. The insurance policies shall be under an occurrence form, but
if only a claims-made form is available to a Party, then such Party shall continue to maintain such insurance after the expiration or termination of this Agreement for the longer of (a) a period of five (5) years following termination or
expiration of this Agreement in its entirety, or (b) with respect to a particular Party, last sale of a Licensed Product (or but for expiration or termination, would be considered a Licensed Product) sold under this Agreement by a Party.

	14.10	Effects of Termination by Denali with cause. In the event of a termination of this Agreement in its entirety or on an Accepted Fcab
Target-by-Accepted Fcab Target or Accepted Fab Target-by-Accepted Fab Target basis by
Denali pursuant to Section 14.4, or Section 14.7, the following terms and conditions will apply, provided, however, that if the termination relates only to a Terminated Target, then the following provisions will only apply
with respect to such Terminated Target: 

  

	 	(a)	All rights and licenses granted by Licensor relating to the mAb2 or Licensed Products with respect to a Terminated Target hereunder shall immediately terminate.
Except as expressly set forth in this ARTICLE 14, Denali and its Affiliates and Sublicensees will have no further rights to use any Licensor Background IP, Licensor Program IP or Joint Program IP to Exploit any mAb2 or Licensed Products for which this Agreement has been terminated; 

  

	 	(b)	The obligations under ARTICLE 6 shall immediately terminate with respect to the Terminated Target and the corresponding mAb2 or Licensed Products for which
this Agreement has been terminated; and 

  

	 	(c)	All rights and licenses granted by Denali relating to the mAb2 or Licensed Products with respect to a Terminated Target under Section 8.3.1 shall
immediately terminate; provided, notwithstanding anything herein to the contrary, that all rights and licenses granted or to be granted by Denali for other Terminated Targets pursuant to Section 8.3.2 or this Section 14.10
shall survive in full force and effect. 

  

	14.11	Remedies. Except as otherwise expressly provided herein, termination of this Agreement in accordance with the provisions hereof shall not limit remedies that may otherwise be available in law or
equity. 

  
 Confidential 

- 118 - 

	14.12	Accrued Rights; Surviving Obligations. 

  

	 	14.12.1	Termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of a Party prior to such termination or expiration, including any amounts
due under ARTICLE 9. Such termination or expiration shall not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement. Without limiting the foregoing, the following Sections
shall survive such termination or expiration 4.12, 6.4, 8.3.2, 8.4, 8.5, 9.13 through 9.19, 10.1, 10.2.4, 12.3, 14.3, 14.9, 14.10, 14.11, 14.12, 15.4 through 15.14 and ARTICLE 11 and ARTICLE 13. 

 

	 	14.12.2	Notwithstanding the termination of Denali’s licenses and other rights under this Agreement, Denali shall have the right for one (1) year after the effective date of such termination to sell or otherwise
dispose of all mAb2 or Licensed Product then in its inventory, as though this Agreement had not terminated, and such sale or disposition shall not constitute infringement of Licensor’s or its
Affiliates’ Patent or other intellectual property or other proprietary rights. For purposes of clarity, Denali shall continue to make payments thereon as provided in ARTICLE 9 (as if this Agreement had not terminated). 

ARTICLE 15 

MISCELLANEOUS 
  

	15.1	 Force Majeure. Neither Party (which for the purposes of this Section 15.1 shall include F-star Ltd and F-star GmbH) shall be held liable or responsible to the other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in
fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from events beyond the reasonable control of the non-performing

Party, including fires, floods, earthquakes, hurricanes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, riots,
civil commotion, strikes, lockouts, or other labor disturbances (whether involving the workforce of the non-performing Party or of any other Person), acts of God or acts, omissions or delays in acting by any
governmental authority (except to the extent such delay results from the breach by the non-performing Party or any of its Affiliates of any term or condition of this Agreement). The non-performing Party shall notify the other Party of such force majeure within [***] days after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration,
and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use
commercially reasonable efforts to remedy its inability to perform. 

  

	15.2	Potential Competition Review. 

  

	 	15.2.1	If the act of exercise of any License Option requires the making of filings under the Hart-Scott-Rodino Antitrust Improvements Act (the “HSR Act”), or under any similar pre-merger or antitrust notification provision in the European Union or any other jurisdiction, or if Denali’s election not to exercise a License Option results in Licensor being required to make any filings
under the HSR Act or under any similar pre-merger or antitrust notification provision in the European Union or any other jurisdiction, then all rights and obligations related to Denali exercising any License
Option or Denali’s decision not to proceed with the exercise of a License Option will be tolled until the applicable waiting period has expired or been terminated or until approval or clearance from the reviewing authority has been received,
and each Party agrees to diligently make any such filings and respond to any request for information to expedite review of such transaction and minimize or avoid any delays in payments.

*** Certain information in this agreement has been omitted and filed separately with the Securities and Exchange Commission. [***] indicates that text has been

	 	15.2.2	If the antitrust enforcement authorities in the U.S. make a second request under the HSR Act, or any antitrust enforcement authority in another jurisdiction commences an investigation related to Denali exercising
a License Option or a decision by Denali not to exercise a License Option, then the Parties will, in good faith, cooperate with each other and take reasonable actions to attempt to (a) resolve all enforcement agency concerns about the
transaction under investigation, and (b) diligently oppose any enforcement agency opposition to such transaction. If the enforcement agency files a formal action to oppose the transaction, the Parties will confer in good faith to determine the
appropriate strategy for resolving the enforcement agency opposition, including, and where appropriate, the renegotiation of their obligations under this Agreement with respect to the exercise of any License Option, with the objective of placing
each Party, to the maximum extent possible, in the same economic position that each Party would have occupied if Denali’s decision to proceed with exercise of the License Option or not to proceed with exercise of the License Option had been
permitted. Notwithstanding the foregoing, nothing in this Section 15.2 will require either Party to divest, sell, license or otherwise dispose of any assets, entities or facilities. 

 

	15.3	Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States or other countries that may be imposed on the Parties from time
to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time
of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate agency or other governmental entity in accordance with Applicable Law.

	15.4	Assignment. 

  

	 	15.4.1	Without the prior written consent of the other Party, such consent not to be unreasonably withheld, conditioned or delayed, no Party shall sell, transfer, assign, delegate, pledge, or otherwise dispose of,
whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, that a Party may make such an assignment without the other Party’s consent to (a) [***], or
(b) in the case of Licensor, to [***], or (c) to [***]. With respect to an assignment to [***], or in the case of Licensor, to [***], the assigning Party shall remain responsible for the performance by [***] of the rights and obligations
hereunder. Any attempted assignment or delegation in violation of this Section 15.4 shall be void and of no effect. All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the
benefit of and be enforceable by and against the successors and permitted assigns of Licensor or Denali, as the case may be. The permitted assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement.
Without limiting the foregoing, the grant of rights set forth in this Agreement shall be binding upon any successor or permitted assignee of Licensor, and the obligations of Denali, including the payment obligations, shall run in favor of any such
successor or permitted assignee of Licensor’s benefits under this Agreement. 

  

	 	15.4.2	 Notwithstanding anything to the contrary herein, in the event of the acquisition of a controlling (as such
term is used in the definition of Affiliate) interest in Licensor, F-star Ltd, F-star GmbH or Denali the acquirer of such Person shall not be considered to be an
Affiliate of such Person for the purposes of this Agreement including for the purposes of the definition Control in respect of the intellectual property of the Parties and

ARTICLE 6. For clarity, any Know-How, Patents or other intellectual property rights or other assets owned or Controlled by an acquirer or its
Affiliates before such an acquisition of such Person or which were subsequently generated by the acquirer, or an Affiliate of the acquirer which is not Licensor or an Affiliate of Licensor immediately prior to the acquisition, will not be Controlled
by such Person after such Change in Control for purposes of this Agreement or subject to ARTICLE 6, except to the extent that Licensor, F-star GmbH, F-star Ltd or
any of their respective Affiliates owned or Controlled such Know-How, Patents or other intellectual property rights or other assets before such acquisition. 

 

	15.5	Severability. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be
materially and adversely affected thereby, (a) such provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof,
(c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid, or
unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and reasonably acceptable
to the Parties. To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render any provision hereof illegal, invalid, or unenforceable in any respect. 

 

	15.6	Governing Law, Jurisdiction and Service. 

  

	 	15.6.1	 Governing Law. This Agreement or the performance, enforcement, breach or termination hereof shall be
interpreted, governed by and construed in accordance with the laws of England, excluding any conflicts or choice of 

  
 Confidential 

- 123 - 

	 	
law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction; provided, that all questions concerning
(a) inventorship of Patents under this Agreement shall be determined in accordance with Section 10.1.3(b) and (b) the construction or effect of Patents shall be determined in accordance with the laws of the country or other
jurisdiction in which the particular Patent has been filed or granted, as the case may be. The Parties agree to exclude the application to this Agreement of the United Nations Convention on Contracts for the International Sale of Goods.

  

	 	15.6.2	Service. Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in Section 15.8.2 shall be effective service of process for any
action, suit, or proceeding brought against it under this Agreement in any such court. 

  

	15.7	Dispute Resolution. Except for disputes resolved by the procedures set forth in Sections 2.8 and 9.18, if a dispute arises between the Parties in connection with or relating to this Agreement or any
document or instrument delivered in connection herewith (a “Dispute”), it shall be resolved pursuant to this Section 15.7. 

  

	 	15.7.1	General. Any Dispute shall first be referred to the Senior Officers of the Parties, who shall confer in good faith on the resolution of the issue. Any final decision mutually agreed to by the Senior Officers
shall be conclusive and binding on the Parties. If the Senior Officers are not able to agree on the resolution of any such issue within thirty (30) days (or such other period of time as mutually agreed by the Senior Officers) after such issue
was first referred to them, then, except as otherwise set forth in Section 15.7.2, either Party may, by written notice to the other Party, elect to initiate arbitration proceedings pursuant to the procedures set forth in
Section 15.7.3 for purposes of having the matter settled. 

  
 Confidential 

- 124 - 

	 	15.7.2	Intellectual Property Disputes. In the event that a Dispute arises with respect the validity, scope, enforceability, inventorship or ownership of any Patent, trademark or other intellectual property rights, and
such Dispute cannot be resolved in accordance with Section 15.7.1, and except with respect to determination of inventorship for a Joint Fcab in accordance with Section 1.78, unless otherwise agreed by the Parties in writing,
such Dispute shall not be submitted to arbitration in accordance with Section 15.7.3 and instead, either Party may initiate litigation in a court of competent jurisdiction, notwithstanding Section 15.6, in any country or
other jurisdiction in which such rights apply. 

  

	 	15.7.3	Arbitration. Should the informal resolution mechanism of Section 15.7.1 prove unsuccessful within the allotted period, then the Parties shall submit their dispute to binding
arbitration [***]. Each Party shall appoint one arbitrator who at their turn shall nominate the chairperson, who shall be qualified in [***]. If a Party does not appoint its arbitrator within fifteen (15) days following the expiry of the
allotted period, then such arbitrator shall be selected in accordance with the then current rules of [***]. Any arbitrator so selected shall have substantial experience in the pharmaceutical industry. The arbitration shall be conducted, and all
documents submitted to the arbitrators shall be, in English. The arbitrators shall have the power to include an award of attorneys’ fees and costs to the prevailing Party, but shall have no power to award punitive, special, incidental or
consequential damages. The arbitrator’s decision and award shall be final and binding upon all Parties. Subject to any award that the arbitrators may make, each Party shall bear its own costs for its counsel and other expenses, and the Parties
shall equally share the costs of the arbitration. Judgment upon the award rendered by arbitration may be issued and enforced by any court having competent jurisdiction.

and any losses, costs, claims, liabilities, damages, demands and expenses suffered or incurred by F-star arising directly out of the Guaranteed Obligations
not being recoverable for any reason or any failure of the Company to pay any of its obligations or liabilities in respect of the Guaranteed Obligations. 

  

	11.3.	This guarantee is and shall cover the ultimate balance from time to time owing to F-star by the Company in respect of the Guaranteed Obligations. 

 

	11.4.	The liability of the Buyer under this clause 11 shall not be terminated by: 

  

	 	(a)	any intermediate payment, settlement of account or discharge in part of the Guaranteed Obligations; 

  

	 	(b)	any variation, extension, discharge, compromise, dealing with, exchange or renewal of any right or remedy which F-star may now or after the date of this guarantee have from or
against any of the Company and any other person in connection with the Guaranteed Obligations; 

  

	 	(c)	any amendment, variation, novation, replacement or supplement of or to any of the Guaranteed Obligations;

 Confidential 

29 

	11.5.	Any release, discharge or settlement between the Buyer and F-star in relation to this guarantee shall be conditional on no right, disposition or payment to F-star by the Buyer, the Company or any other person in respect of the Guaranteed Obligations being avoided, set aside or ordered to be refunded under any enactment or law relating to breach of duty by any person,

	12.	SELLERS’ REPRESENTATIVE 

  

	12.1.	Each Seller hereby irrevocably and unconditionally appoints the Sellers’ Representative as sole representative agent and
attorney-in-fact to act on such Seller’s behalf for all purposes relating to this Agreement after Completion and each agreement and document ancillary thereto,
including for the purposes of:

	 	(b)	making elections and granting any consent or approval on behalf of such Seller under this Agreement;

under, this Agreement or any other Transactional Document; 

  

	 	(e)	confirming the allocation between the Sellers of the Contingent Consideration to be made under this Agreement; 

  

	 	(f)	enforcing, negotiating, compromising, settling and releasing on behalf of such Seller any rights and claims (including legal proceedings and ADR) which he may have, threaten or pursue against the Buyer (or any other
person) in respect of any breach of, or right under, this Agreement or any other Transactional Document or any Dispute; 

  
 Confidential 

30 

	 	(g)	consent or agree to any amendment to this Agreement or to waive any terms and conditions of this Agreement providing rights or benefits to the Sellers (other than with respect to the payment of the Total Consideration)
in accordance with the terms hereof and in the manner provided herein; 

  

	 	(h)	taking any and all actions that may be necessary or desirable in connection with the payment by the Sellers of the costs and expenses incurred under this Agreement; and 

 

	 	(i)	generally taking any and all other actions and doing any and all other things provided in or contemplated by this Agreement and each agreement and document ancillary thereto to be performed by such Seller or the
Sellers’ Representative. 

  

	12.2.	Each Seller hereby irrevocably (by way of security for the performance of his obligations under this Agreement) appoints the Sellers’ Representative as its agent with full authority on his behalf and in the
Seller’s name, as applicable, or otherwise, to do all acts and to execute and deliver such documents or deeds as are required by law or as may, in the reasonable opinion of the Sellers’ Representative, be required or convenient to give
effect to the matters described in clause 12.1. 

  

	12.3.	The Sellers’ Representative shall act in good faith in accordance with what the Sellers’ Representative believes to be the best interests of the Sellers when exercising any power or authority conferred on
under this clause 12. 

  

	12.4.	Save in the event of fraud, any action undertaken or omitted by the Sellers’ Representative with the written approval of a Sellers’ Majority shall be conclusively deemed to be in accordance with the
requirements of clause 12.3 provided that, for the avoidance of doubt, such approval shall not be necessary. 

  

	12.5.	The Sellers’ Representative may resign at any time. The Sellers’ Representative may consult with any Seller to the extent a claim is threatened or pursued by the Buyer in respect of any breach of, or right
under, this Agreement or any other Transactional Document and which specifically concerns any actual or alleged act or default of that Seller. 

  
 Confidential 

31 

	12.6.	The Sellers may, by written notice signed by a Sellers Majority (a “Change Of Sellers’ Representative Notice”), replace a resigning Sellers’ Representative or remove an incumbent
Sellers’ Representative from such position and appoint another person to act as Sellers’ Representative in substitution thereof (a “New Sellers’ Representative”). A Change Of Sellers’ Representative
Notice shall be effective only once a copy thereof has been served on both the incumbent Sellers’ Representative and the Buyer. 

  

	12.7.	A New Sellers’ Representative so appointed shall, with effect from the time of its appointment, execute a deed of adherence in favour of the Sellers and the Buyer pursuant to which it shall agree to adhere to, and
be bound by, this Agreement as though named herein as the Sellers’ Representative and the parties agree that such substitute New Sellers’ Representative shall be conferred the rights, power and authorities (including as set out in this
clause 12) of the Sellers’ Representative as set out in this Agreement and entitled to directly enforce the same (notwithstanding that it may not have initially been a signatory hereto). A copy of such deed of adherence shall be delivered to
the Buyer at the same time as the Change Of Sellers’ Representative Notice is served thereon under clause 12.6. 

  

	12.8.	If at any time a New Sellers’ Representative is appointed in accordance with clause 12.6, if required by the Buyer, the Sellers’ Representative hereby undertakes to do all such things as may be necessary to
novate the Escrow Agreement from the previous Sellers’ Representative to the New Sellers’ Representative. 

  

	12.9.	Any action taken or any exercise of powers under this Agreement by the Sellers’ Representative or any New Sellers’ Representative shall be binding on each Seller for the purposes of this Agreement, shall be
deemed to be done by each Seller, and the Buyer shall be entitled to assume that any action taken by the Sellers’ Representative or any New Sellers’ Representative whose appointment has been notified in accordance with this clause 14 is
binding on all of the Sellers and the parties shall be entitled to rely on the same. The Buyer shall not be required to make further enquiries in respect thereof. The Buyer shall have no obligation to monitor or supervise the Sellers’
Representative or any New Sellers’ Representative. The Buyer shall not be liable to any of the Sellers for any action taken or omitted to be taken by the Sellers’ Representative or any New Sellers’ Representative. 

  
 Confidential 

32 

	12.10.	All costs (including legal costs) and expenses (including Tax), in each case, of any nature whatsoever, of the Sellers’ Representative shall be borne by the Sellers in the proportions set out in column C of the
table in Schedule 1 (The Sellers). 

  

	12.11.	The Sellers’ Representative shall have no liability or obligation to take any action on behalf of any Seller under the powers and authorities conferred on the Sellers’ Representative by this Agreement where
such action may result in the Sellers’ Representative incurring any cost, expense or liability unless the Sellers’ Representative is satisfied with any arrangements made by (or on behalf of) the Sellers for the satisfaction or re-imbursement of such costs, expenses and liabilities. 

  

	12.12.	Upon Completion, and subject to receipt by the Sellers’ Representative of the cash sum provided for in clause 3.3(a), the Sellers’ Representative will retain an amount of [***] from such sum (the
“Expense Fund”), which will be used for the purposes of paying directly, or reimbursing the Sellers’ Representative for, any third party expenses pursuant to this Agreement and the transactions contemplated hereby. The Sellers
will not receive any interest or earnings on the Expense Fund and irrevocably transfer and assign to the Sellers’ Representative any ownership right that they may otherwise have had in any such interest or earnings. The Sellers’
Representative will not be liable for any loss of principal of the Expense Fund other than as a result of its gross negligence or wilful misconduct. The Sellers’ Representative will hold these funds separate from its corporate funds in a
segregated client account, will not use these funds for its operating expenses or any other corporate purposes and will not voluntarily make these funds available to its creditors in the event of bankruptcy. As soon as practicable following the
completion of the Sellers’ Representative’s responsibilities, the Sellers’ Representative will distribute the balance of the Expense Fund to the Payments Administrator for further distribution to the Sellers. For tax purposes, the
Expense Fund shall be treated as having been received and voluntarily set aside by the Sellers at the time of Completion. The parties agree that the Sellers’ Representative is not responsible for any tax withholding or reporting or acting as a
withholding agent or in any similar capacity in connection with the Expense Fund. 

  

	12.13.	 The Sellers’ Representative will incur no liability of any kind with respect to any action or omission by
the Sellers’ Representative in connection with Sellers’ Representative’s services pursuant to this Agreement and any agreements ancillary hereto, except in the event of liability directly resulting from the Sellers’
Representative’s gross negligence or

wilful misconduct. The Sellers’ Representative shall not be liable to any Seller as a result of any action or omission that is taken (or not taken) in good faith pursuant to the advice of
external legal counsel in the proper performance of its obligations under this Agreement. The Sellers will, severally and not jointly, on a pro rata basis equal to the portion of Total Consideration each such Seller is entitled to receive pursuant
to this Agreement compared to the aggregate Total Consideration entitled to be received by all Sellers, indemnify, defend and hold harmless the Sellers’ Representative from and against any and all losses, liabilities, damages, claims,
penalties, fines, forfeitures, actions, fees, costs and expenses (including the fees and expenses of counsel and experts and their staffs and all expense of document location, duplication and shipment) (collectively, “Representative
Losses”) arising out of or in connection with the Sellers’ Representative’s execution and performance of this Agreement and any agreements ancillary hereto, in each case as such Representative Loss is suffered or incurred;
provided, that in the event that any such Representative Loss is finally adjudicated to have been directly caused by the gross negligence or wilful misconduct of the Sellers’ Representative, the Sellers’ Representative will reimburse the
Sellers the amount of such Representative Loss to the extent attributable to such gross negligence or wilful misconduct. If not paid directly to the Sellers’ Representative by the Sellers, any such indemnified Representative Losses may be
recovered by the Sellers’ Representative from (i) the funds in the Expense Fund, (ii) the amounts in the Escrow Amount at such time as remaining amounts would otherwise be distributable to the Sellers, and (iii) from any
Milestone Payments at such time as any such amounts would otherwise be distributable to the Sellers; provided, that while this section allows the Sellers’ Representative to be paid from the Expense Fund, the Escrow Amount and the Milestone
Payments, this does not relieve the Sellers from their obligation to promptly pay such Representative Losses as they are suffered or incurred, nor does it prevent the Sellers’ Representative from seeking any remedies available to it at law or
otherwise. In no event will the Sellers’ Representative be required to advance its own funds on behalf of the Sellers or otherwise. For the avoidance of doubt and notwithstanding anything in this Agreement to the contrary, the limitations on
liability of the Sellers set forth elsewhere in this Agreement are not intended to be applicable to the indemnities provide to the Sellers’ Representative under this clause 12.13. The Sellers acknowledge and agree that the foregoing indemnities
will survive the resignation or removal of the Sellers’ Representative or the termination of this Agreement. 

  
 Confidential 

34 

	13.	PAYMENTS 

  

	13.1.	Payments to be made to the Sellers under this Agreement shall be made in US dollars by telegraphic transfer of immediately available funds to such account controlled by the Payments Administrator as may be notified by
the Payments Administrator or the Sellers’ Representative in writing to the Buyer. 

  

	13.2.	Payments to be made to the Buyer under this Agreement shall be made in US dollars by telegraphic transfer of immediately available funds to such account as may be notified in writing by the Buyer to the Payments
Administrator. 

  

	13.3.	The payment of any sum to the Buyer by or on behalf of any of the Sellers will discharge the obligations of the Sellers to pay the sum in question and the Sellers shall not be concerned to see the application of the
monies so paid. 

  

	13.4.	The payment of any sum to the Payments Administrator by or on behalf of the Buyer will discharge the obligations of the Buyer to pay the sum in question and the Buyer shall not be concerned to see the application of the
monies so paid. 

  

	14.	ANNOUNCEMENTS 

  

	14.1.	Subject to clause 14.2, no party (the “disclosing party”) may, before or after Completion, make or issue a public announcement or press release concerning the transactions referred to in this Agreement
other than the Press Release unless it has first obtained the written consent of the Sellers (prior to Completion, if the disclosing party is the Buyer) or the Sellers’ Representative (after Completion, if the disclosing party is the Buyer), or
of the Buyer (if the disclosing party is a Seller) (in either case, the “other party”), which consent may not be unreasonably withheld or delayed. 

 

	14.2.	Clause 14.1 does not apply to a public announcement or press release required by law, by a rule of a listing authority by which a party’s shares are listed, a stock exchange on which a party’s shares are
listed or traded or by a governmental authority or other authority with relevant powers to which either party is subject or submits, whether or not the requirement has the force of law, provided that the public announcement, communication or
circular shall so far as is practicable be made after consultation with the other party and after taking into account the reasonable requirements of the other party as to its timing, content and manner of making or despatch.

to adhere to them. 

  

	15.4.	Notwithstanding anything in this Agreement to the contrary, following Completion, the Sellers’ Representative shall be permitted to: (i) after the public announcement (if any) of the transaction contemplated
by this Agreement, publicly announce that it has been engaged to serve as the Sellers’ Representative in connection with the transaction as long as such announcement does not disclose any of the other terms hereof and (ii) disclose

	17.2.	The failure to exercise or delay in exercising a right or remedy provided by this Agreement or by law does not impair or constitute a waiver of the right or remedy or an impairment of or a waiver of other rights or
remedies. No single or partial exercise of a right or remedy provided by this Agreement or by law prevents further exercise of the right or remedy or the exercise of another right or remedy. 

  
 Confidential

the extent possible and without limiting the liability of any Seller or Warrantor (as the case may be) under this Agreement, be treated as a reduction in the purchase price payable by the Buyer for the Shares. 

 

	17.6.	All payments made by a Seller under this Agreement shall be made gross, free of right of counterclaim or set off and without deduction or withholding of any kind other than deductions or withholding required by law.

therein, stating the reasons for the disagreement in reasonable detail including each disputed item, the amount in dispute and the basis for such dispute (the “Sellers’ Disagreement Notice”), the Draft Completion
Accounts shall constitute the Completion Accounts and shall be final and binding on the parties for all purposes in accordance with paragraph 12 of this Part A of Schedule 4.

Account.

Buyer, any of the Sellers or the Reporting Accountants or manifest error of the Reporting Accountants (when the relevant part of their determination shall be void). In particular, without limitation, their determination shall be deemed to be
incorporated into the Draft Completion Accounts, which shall then be final and binding on the parties for the purposes of this Schedule 4, save as stated above in the event of fraud or manifest error. 

 

	8.	The Buyer and the Sellers’ Representative shall co-operate with the Reporting Accountants and comply with their reasonable requests made in connection with the carrying out
of their duties pursuant to their engagement under the terms of this Agreement.

 Part D: Preparation of Management Accounts 

 

	1.	ACCOUNTING POLICIES 

  

	 	a.	PRESENTATION OF MANAGEMENT ACCOUNTS 

 CRITICAL ACCOUNTING JUDGMENTS
AND KEY SOURCES OF ESTIMATION UNCERTAINTY 
 In the application of the Company’s accounting policies, management make judgments,
estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be
relevant. Actual results may differ from these estimates. 
 The estimates and underlying assumptions are reviewed on an ongoing basis.
Revisions to accounting estimates are recognised in the period of the revision and future periods if the revision affects both current and future periods. 
  

	 	b.	OVERALL CONSIDERATIONS 

 The principal accounting policies adopted in the preparation of
the management accounts are set out below. 
  

	 	i.	BASIS OF PREPARATION OF MANAGEMENT ACCOUNTS 

 These management accounts have been
prepared in accordance with EU endorsed International Financial Reporting Standards (IFRS) and interpretations issued by the IFRS Interpretations Committee (IFRS IC) and the Companies Act 2006 applicable to companies reporting under IFRS. The
management accounts have been prepared under the historical cost convention. 

  
 Confidential 

56 

	 	ii.	GOING CONCERN 

 Management prepare management accounts on a going concern basis unless
they intend to liquidate the business or to cease trading, or have no realistic alternative but to do so. In deciding whether the going concern basis is appropriate, the directors examine existing budgets and forecasts, assess borrowing
requirements, and review other information as needed. 
  

	 	iii.	NEW AND AMENDED STANDARDS ADOPTED BY THE COMPANY 

 In any period, new or amended
standards and interpretations are considered for adoption. Other standards, amendments and interpretations which are effective for the period are considered where they material to the Company. 

 

	 	c.	RECEIVABLES 

 Receivables are recognised initially at fair value less provision for
impairment. The Company provides an allowance for uncollectible accounts based on prior experience and management’s assessment of the collectability of existing specific accounts. 

 

	 	d.	CASH AND CASH EQUIVALENTS 

 Cash and cash equivalents comprises cash on hand and demand
deposits, and other short-term and highly liquid investments with original maturities of three months or less that are readily convertible to a known amount of cash and are subject to an insignificant risk of
changes in value. 
  

	 	e.	EQUITY AND RESERVES 

 Ordinary and preferred shares are classified as equity. Issued
capital represents the nominal value of shares that have been issued. Retained earnings includes all current period retained profits and accumulated losses. 
  

	 	f.	TRADE PAYABLES 

 Trade payables are obligations to pay for goods or services that have
been acquired in the ordinary course of business from suppliers. Trade and other payables are stated at cost, which approximates fair value due to the short term nature of these liabilities. Trade payables are classified as current liabilities if
payment is due within one period or less. If not, they are presented as non-current liabilities. 

  
 Confidential 

57 

	 	g.	REVENUE RECOGNITION 

 Revenue is measured at the fair value of the consideration
received or receivable and is stated net of value added taxes. Revenue is recognised when it is probable that future economic benefits will flow to the Company and those benefits can be measured reliably. Revenue on the sale of an asset (e.g. the
outright sale or assignment of a licence) is only recognised when, inter alia, the significant risks and rewards of ownership have been transferred to the buyer and the Company does not retain either control of the goods, or continuing involvement,
to the degree associated with ownership. 
 Where, as part of a licence agreement, services are performed by an indeterminate number of acts
over a specified period of time, revenue for such services is recognised on a straight-line basis over the specified period unless there is evidence that some other method represents better the stage of completion. 

 

	 	h.	SHARE BASED PAYMENTS 

 A share option compensation charge is not recognised in the
monthly management accounts. 
  

	 	i.	TAXATION AND DEFERRED TAX 

 A tax credit or charge is not reflected in the monthly
management accounts. 
 Deferred tax is not reflected in the monthly management accounts. 

 

	 	j.	FINANCIAL INSTRUMENTS 

  

	 	i.	FINANCIAL ASSETS 

 All financial assets relate to trade and other receivables, which are
stated at their recoverable amount, which approximates the fair value due to the short term nature of these assets. 
  

	 	ii.	RISK MANAGEMENT POLICY 

 The Company undertakes transactions denominated in foreign
currencies and as such is exposed to currency risk due to fluctuations in foreign exchange rates. The Company does not use derivative instruments to reduce exposure to foreign exchange risk. 

 

	 	iii.	FINANCIAL LIABILITIES 

 Trade and other payables are stated at cost. This approximates
fair value due to the short term nature of these liabilities. 

  
 Confidential 

58 

	 	k.	FOREIGN CURRENCY TRANSLATION 

 Foreign currency transactions are translated at the rates
of exchange in effect at the dates of the transaction. Resulting foreign currency denominated monetary assets and liabilities are translated at the rates of exchange in effect at the balance sheet date. Gains and losses on foreign exchange are
recognised in the income statement.

personnel, and to any relevant assets, accounts, documents or records within its control, for the purposes of enabling the Sellers to assess the Third Party Claim and to exercise their rights under this paragraph 13.2. 

 

	13.3.	The Buyer shall have the right in its sole discretion to conduct the defence of and to settle or resolve such Third-Party Claim. However, without the prior written consent of the Sellers’ Representative, which
consent will not be unreasonably withheld, delayed or conditioned, [***]. In the event that the Sellers’ Representative has consented in writing [***], neither the Sellers’ Representative nor any Seller shall have any power or authority to
object [***]. 

  

	13.4.	The Sellers shall indemnify the Buyer in respect of all costs, charges and expenses that are reasonably and properly incurred by the Buyer (or any other member of the Buyer’s Group) in connection with the defence

	14.	PROVISION OF INFORMATION

 If any potential Claim arises as a result of a contingent or
unquantifiable liability of any Buyer’s Group Undertaking, each Seller will not be obliged to pay any sum in respect of the potential Claim until the liability either ceases to be contingent or becomes quantifiable; provided, however, that this
paragraph 17 shall not restrict the Buyer from setting off and deducting the Buyer’s reasonable estimate of any such potential Claim from Contingent Consideration, as permitted by paragraph 11.

 F-star Announces Collaborative Agreement with Denali Therapeutics
for the 
 Development of a Multispecific Antibody Platform to Deliver Therapeutics 

Across the Blood-Brain Barrier 

Cambridge, UK and South San Francisco, USA – 25 August 2016 – F-star, a
biopharmaceutical company developing novel bispecific antibodies, announces a collaborative agreement with Denali Therapeutics Inc. (Denali), a biotechnology company focused on neurodegenerative disorders, to research and develop antibodies for the
delivery of medicines across the blood-brain barrier (BBB) into the central nervous system (CNS). 
 The collaboration will leverage F-star’s Modular Antibody TechnologyTM and Denali’s expertise in the development of therapeutics for neurological diseases to generate FcabsTM (constant Fc-domains with antigen-binding activity) which can bind to transporters in the BBB. Using the “plug-and-play” properties of the platform, these Fcabs can be rapidly inserted into any existing antibody to generate a full size bispecific antibody (mAb2 TM) which can both cross the BBB, as well as bind to specific targets within the CNS. This mechanism has the potential to treat neurological diseases by acting on specific targets in the brain. 

The agreement is with F-star Gamma Limited (F-star Gamma), a new Asset-Centric
Vehicle in the F-star family. Under the agreement, Denali will make upfront payments to F-star totalling $6 million. Denali has the option to nominate a pre-specified number of Fcab targets. F-star Gamma will also receive research funding and is eligible for technical milestone payments. In addition, Denali also has the option
to acquire F-star Gamma prior to the initiation of the first Phase 1 clinical trial in return for aggregate exercise and milestone payments to the F-star Gamma
shareholders of up to $450M in total. If Denali does not exercise the option to acquire F-star Gamma, it has the right to license a pre-specified number of mAb2
based on each Fcab generated by F-star Gamma, in return for license fees, development, regulatory and commercial milestones payments with a potential aggregate value of $1B and tiered royalties on product
sales.

 John Haurum, CEO of F-star, commented: “Our Modular
Antibody Technology is ideally suited to deliver biologic drugs into the Central Nervous System across the blood-brain barrier. Denali’s scientists are world leaders in understanding the complex mechanisms of the blood-brain barrier and we look
forward to collaborating with the team to unlock the potential of our platform and develop more efficient treatments for neurological disorders.” 

Ryan Watts, CEO of Denali, said: “We are excited to partner with F-star to tackle one of the toughest
problems in medicine, delivery of biologics across the blood-brain barrier. F-star’s deep expertise and proven track record of engineering novel antibodies offer a promising approach for the treatment of
neurological disease.”

	 	8.3.2	In the event that Lonza believes that a Batch has been incorrectly rejected, Lonza may require that Customer provide to it Batch samples for testing. Lonza may retain and test the samples of such Batch. In the event of
a discrepancy between Customer’s and Lonza’s test results such that Lonza’s test results fall within relevant Specifications, or there exists a dispute between the Parties over the extent to which such failure is attributable to a
given Party, the Parties shall cause an independent laboratory promptly to review records, test data and perform comparative tests and analyses on samples of the Product that allegedly fails to conform to Specifications. Such independent laboratory
shall be mutually agreed upon by the Parties. The independent laboratory’s results shall be in writing and shall be final and binding save for manifest error. Unless otherwise agreed to by the Parties in writing, the costs associated with such
testing and review shall be borne by the Party against whom the independent laboratory rules. 

  

	 	8.3.3	Any Batch that failed to conform with the Specifications, including a batch of extraordinary low yield caused by Lonza’s technical error, shall be a “Failed Batch”. In the event that it is agreed by the
Parties or determined (by the independent laboratory) that such Failed Batch was due to [***] (a “Lonza Responsibility”) then Lonza shall manufacture a replacement Batch as promptly as possible, in light of available manufacturing
capacity, after the Lonza Responsibility is agreed or determined and in any case as soon as reasonably possible after confirmation of Lonza Responsibility is agreed or determined. Where possible, such replacement Batch shall be manufactured with the
next scheduled cGMP Batch. Customer acknowledges and agrees that its sole remedy with respect to a Failed Batch that is a Lonza Responsibility is as set forth in this Clause 8.3.3, and in furtherance thereof, Customer hereby waives all other
remedies at law or in equity regarding the foregoing claims. Lonza shall not be responsible for the cost of Raw Materials or Customer Materials consumed in any Failed Batch except to the extent set forth in this Clause 8.3.3. If Customer receives a
refund in respect of the Failed Batch that is a Lonza Responsibility or Customer did not pay for the Failed Batch that was a Lonza Responsibility, Customer shall pay the Batch Price for the replacement Batch and any Raw Materials and Resins used
therein. 

  

	 	8.3.4	If any Failed Batch is not a Lonza Responsibility then Lonza shall, if Customer wishes, manufacture a replacement Batch at Customer’s cost and subject to available capacity at the Facility.

Confidential Information shall include information disclosed in any form including but not limited to in writing, orally, graphically or in electronic or other form to the Receiving Party, observed by the Receiving Party or its employees, agents,
consultants, or representatives, or otherwise learned by the Receiving Party under this Agreement, which the Receiving Party knows or reasonably should know is confidential or proprietary. 

 

	 	13.2	Notwithstanding the foregoing, Receiving Party may disclose to any courts and/or other authorities Confidential Information which is or will be required pursuant to applicable governmental or administrative or public
law, rule, regulation or order. In such case the Party that received the Confidential Information will, to the extent legally permitted, inform the other Party promptly in writing and cooperate with the Disclosing Party in seeking to minimize the
extent of Confidential Information which is required to be disclosed to the courts and/or authorities. 

  

	 	13.3	The obligation to maintain confidentiality under this Agreement does not apply to Confidential Information, which: 

13.3.1 at the time of disclosure was publicly available; or

	 	13.3.2	is or becomes publicly available other than as a result of a breach of this Agreement by the Receiving Party; or 

  

	 	13.3.3	as the Receiving Party can establish by competent proof, was rightfully in its possession at the time of disclosure by the Disclosing Party and had not been received from or on behalf of Disclosing Party; or

  

	 	13.3.4	is supplied to a Party by a Third Party which was not in breach of an obligation of confidentiality to Disclosing Party or any other Party; or 

 

	 	13.3.5	is developed by the Receiving Party independently from and without use of the Confidential Information, as evidenced by contemporaneous written records. 

 

	 	13.4	The Receiving Party will use Confidential Information of the other only for the purposes of this Agreement and will not make any use of the Confidential Information for its own separate benefit or the benefit of any
Third Party including, without limitation, with respect to research or product development or any reverse engineering or similar testing. The Receiving Party agrees to return or destroy promptly (and certify such destruction) on Disclosing
Party’s request all written or tangible Confidential Information of the Disclosing Party, except that one copy of such Confidential Information may be kept by the Receiving Party in its confidential files for record keeping purposes only.

  

	 	13.5	Each Party will restrict the disclosure of Confidential Information to such officers, employees, consultants and representatives of itself and its Affiliates who have been informed of the confidential nature of the
Confidential Information and who have a need to know such Confidential Information for the purpose of this Agreement. Prior to disclosure to such persons, the Receiving Party shall bind its and its Affiliates’ officers, employees, consultants
and representatives to confidentiality and non-use obligations no less stringent than those set forth herein. The Receiving Party shall notify the Disclosing Party as promptly as practicable of any
unauthorized use or disclosure of the Confidential Information. Lonza may disclose the Customer’s Confidential Information to Lonza’s Affiliates, contractors and External Laboratories for the purposes of this Agreement and provided the
same are under written obligations of confidentiality that are no less onerous than those contained herein. 

  

	 	13.6	The Receiving Party shall at any time be fully liable for any and all breaches of the confidentiality obligations in this Clause 13 by any of its Affiliates or the employees, consultants and representatives of itself or
its Affiliates, or in the case of Lonza its contractors.

	 	13.7	Each Party hereto expressly agrees that any breach or threatened breach of the undertakings of confidentiality provided under this Clause 13 by a Party may cause irreparable harm to the other Party and that money
damages may not provide a sufficient remedy to the non-breaching Party for any breach or threatened breach. In the event of any breach and/or threatened breach, then, in addition to all other remedies
available at law or in equity, the non-breaching Party shall be entitled to seek injunctive relief and any other relief deemed appropriate by the non-breaching Party.

  

	 	13.8	Neither Party may use or disclose any Confidential Information of the other Party or any its Affiliates in any patent application.

provided herein or extended by mutual written consent of the Parties (the “Term”). No less than eighteen (18) months prior to the fifth anniversary of the Effective Date, the Parties may decide in writing to extend the term of this
Agreement by a further five (5) years (and is so extended the Term shall be construed accordingly). Notwithstanding the foregoing, each Project Plan may have separate term and termination provisions so long as the term of any Project Plan does
not extend beyond the Term.

	 	14.2.1	by either Party if the other Party breaches a material provision of this Agreement or a Project Plan and fails to cure such breach to the reasonable satisfaction of the
non-breaching Party within [***] days ([***] days for non-payment) following written notification of such breach from the non-breaching Party to the breaching Party;
provided, however, that such [***] day period shall be extended as agreed by the Parties if the identified breach is incapable of cure within [***] days and if the breaching Party provides a plan and timeline to cure the breach, promptly commences
efforts to cure the breach and diligently prosecutes such cure (it being understood that this extended period shall be unavailable for any breach regarding non-payment); 

 

	 	14.2.2	by either Party, immediately, if the other Party becomes insolvent, is dissolved or liquidated, makes a general assignment for the benefit of its creditors, or files or has filed against it, (which is not dismissed
within [***] days), a petition in bankruptcy or has a receiver or an administrator appointed for a substantial part of its assets;

	 	14.5	Survival. Termination or expiration of this Agreement for any reason shall not release either Party from any liability which, at the time of such termination or expiration, has already accrued or which is
attributable to a period prior to such termination or expiration and shall not preclude either Party from pursuing any rights and remedies it may have hereunder, or at law or in equity, with respect to any breach of, or default under, this
Agreement. The rights and obligations of each Party which by their nature survive the termination or expiration of this Agreement shall survive the termination or expiration of this Agreement, including Clauses 5,
10-13 and 16 (to the extent relevant). 

  

	15	Force Majeure 

  

	 	15.1	If Lonza is prevented or delayed in the performance of any of its obligations under the Agreement by Force Majeure and gives written notice thereof to Customer specifying the matters constituting Force Majeure together
with such evidence as Lonza reasonably can give and specifying the period for which it is estimated that such prevention or delay will continue, Lonza shall be excused from the performance or the punctual performance of such obligations as the case
may be from the date of such notice for so long as such cause of prevention or delay shall continue. Provided that, if such Force Majeure persists for a period of [***] months or more, either Party may terminate (i) the specific Project Plan
affected by the Force Majeure event or (ii) this Agreement by delivering written notice to the other. 

  

	 	15.2	“Force Majeure” shall be deemed to include any reason or cause beyond Lonza’s reasonable control affecting the performance by Lonza of its obligations under the Agreement, including, but not limited to,
any cause arising from or attributable to acts of God, strike, lockouts, labor troubles, restrictive governmental orders or decrees, riots, insurrection, war, terrorists acts, or the inability of Lonza to be reasonably able to obtain any required
raw material, energy source, equipment, labor or transportation. 

  

	 	15.3	With regard to Lonza, any such event of Force Majeure affecting services or production at its Affiliates or suppliers shall be regarded as an event of Force Majeure. 

 

	16	Miscellaneous 

  

	 	16.1	Severability. If any provision hereof is or becomes at any time illegal, invalid or unenforceable in any respect, neither the legality, validity nor enforceability of the remaining provisions hereof shall in any
way be affected or impaired thereby. The Parties hereto undertake to substitute any illegal, invalid or unenforceable provision by a provision which is as far as possible commercially equivalent considering the legal interests and the Purpose.

	 	16.2	Amendments/Assignment. Modifications and/or amendments of this Agreement must be in writing and signed by the Parties. Lonza shall be entitled to instruct one or more of its Affiliates to perform any of
Lonza’s obligations contained in this Agreement, but Lonza shall remain fully responsible in respect of those obligations. Subject thereto, neither Party may assign its interest under this Agreement without the prior written consent of the
other Party, such consent not to be unreasonably withheld, conditioned or delayed, provided, however that: 

  

	 	(a)	Lonza may assign this Agreement to:
