BACKGROUND: 
  

	(A)	 The Licensed Data are owned by OUI. The Licensed Technology, with the exception of the DM1 Application, is
owned by OUI and MRC. The DM1 Application is owned by OUI, MRC, Association Institut de Myologie, INSERM and Sorbonne Universite (the latter three institutions being the “French Institutions”) pursuant to a co-ownership agreement between OUI and the French Institutions (“Co-ownership Agreement”). Under the Co-ownership
Agreement, the French Institutions have granted to OUI the exclusive right to grant commercial licences to third parties. The Licensed Data and Licensed Technology are connected with OUI Project Numbers [***] and MRC Asset Number: [***], in respect
of cell penetrating peptides for treatment of Duchenne muscular dystrophy, spinal muscular atrophy and other conditions. 


  

	(B)	 The Licensee and Licensors entered into an agreement dated 26 March 2018 (“Original Licence
Agreement”) whereby the Licensors granted the Licensee an exclusive licence to the Licensed Technology as amended by an addendum dated 21 December 2018 (the “Addendum”), 



 

	(C)	 The Licensee and Licensors now wish to amend and restate the terms of the licence granted under the Original
Licence Agreement as amended by the Addendum. 


 AGREEMENT: 

 

	1.	 INTERPRETATION 



 

	1.1	 In this agreement (including its Schedules), any reference to a “clause” or
“Schedule” is a reference to a clause of this agreement or a schedule to this agreement, as the case may be. Words and expressions used in this agreement have the meaning set out in Schedule 1 . 



 

	2.	 GRANT OF LICENCE 



 

	2.1	 The licence granted under the Original Licence Agreement as modified by the Addendum shall, with effect from
the Effective Date, be subject to the terms and conditions of this agreement in lieu of the terms and conditions of the Original Licence Agreement and Addendum which shall have no effect on or after the Effective Date. 



 

	2.2	 For the avoidance of doubt, notwithstanding the reference to certain indications in recital (A) above, the
licence granted under clause 2.3 below is unrestricted as to field and accordingly the Licensee shall be free to use the Licensed Technology in any indication. 



  
 2 














	2.3	 In consideration of the payments required to be made under this agreement by the Licensee, each of the
Licensors grants to the Licensee a licence in the Territory in respect of the Licensed Technology to Exploit the Licensed Product and Licensed Technology on and subject to the terms and conditions of this agreement. Subject to clause 3, the Licence
is exclusive in relation to the Licensed Technology (excluding the Licensed Know-How). The Licence is non-exclusive in relation to the Licensed Know-How. 


  

	2.4	 OUI confirms that it has supplied (and to the extent that it has not, undertakes within [***] of the Effective
Date to supply) the Licensee with all of the Licensed Know-How and the Licensed Data. 


  

	2.5	 The Licensee may grant sub-licences with the prior written consent of OUI or MRC, such consent not to be
unreasonably withheld, conditioned or delayed, provided that: 


  

	2.5.1	 the sub-licensee has obligations to the Licensee commensurate with
those which the Licensee has to each of the Licensors under this agreement, except the financial terms of this agreement or where it is not legally possible to include such obligations in the sub-licence; 



 

	2.5.2	 the nature of the proposed sub-licensee is not likely in OUI’s or
MRC’s reasonable opinion to have any detrimental impact on the reputation of OUI, MRC or of the University; 


  

	2.5.3	 as soon as reasonably practicable following the grant of each sub-licence, the Licensee provides a certified
copy of that sub-licence to each of the Licensors, such copy to be Confidential Information of the Licensee which may be redacted to the extent any information in such sub-licence does not relate to the Licensed Technology, the Licensors and/or this
agreement; 


  

	2.5.4	 the sub-licensee enters into a Deed of Covenant with the Licensors in
the form set out in Schedule 6; and 


  

	2.5.5	 no sub-licence will carry any right to
sub-sub-license (other than a sub-sub-licence of a nature substantially similar to that of clause 2.6 below).



  

	2.6	 In addition to its right under clause 2.5 above, the Licensee shall, without requiring the consent of the
Licensors (or either of them), be entitled to grant sub-licenses (i) to its Affiliates; and (ii) to those persons whom the Licensee (or its Affiliates) contracts to perform research and/or
development services (including clinical trials) on or in relation to Licensed Product but only to the extent necessary for those contractors to perform the work contracted to them. 



 

	2.7	 Any rights not expressly granted under this Agreement are hereby reserved to their respective proprietors.



  

	3.	 RIGHTS REGARDING NON-COMMERCIAL USE 



 

	3.1	 The Licensee grants OUI an irrevocable, perpetual, royalty-free licence to grant the University, and those who
at any time work or have worked on the Licensed Technology, the licence set out in clause 3.2. 


  

	3.2	 Without prejudice to clause 3.4, OU I has granted to the University, and those persons who at any time work or
have worked on the Licensed Technology, a non- transferable, irrevocable, perpetual, royalty-free licence to use the Licensed Technology for Non-Commercial Use and to
publish, the Licensed Technology. 



  
 3 














	3.3	 Without prejudice to clause 3.4, the Licensee hereby grants to MRC a
non- transferable, irrevocable, perpetual, royalty-free licence to use the Licensed Technology for Non-Commercial Use and to publish, the Licensed Technology. MRC also has the right to grant sub-licences to
any persons at MRC or academic/not-for-profit institutions who at any time work or have worked on or funded or whose collaboration with MRC has contributed to the
creation of, the Licensed Technology for Non-Commercial Use only. 


  

	3.4	 For the avoidance of doubt, the Licensee agrees that each of MRC, OUI and the University is free to use,
publish (subject to clauses 3.6 and 3.7 below) or grant licences to the Licensed Know-How in any fields in any territories, as it sees fit. 



 

	3.5	 The Licensors acknowledge that Licensee has an expectation of commercial confidentiality in relation to
Confidential Information provided by the Licensee to the Licensors in relation to all pre-clinical and clinical uses of its lead candidate Licensed Products, and that such uses incur liability risks and
regulatory obligations. 


  

	3.6	 Where the University wishes to submit a publication including the Licensed
Know-How and/or the Licensed Data (together the “Relevant Know-How and Data”), OUI shall procure that the University will use all reasonable endeavours to
submit such draft publication to the Licensee in writing not less than [***] in advance of the submission for publication. The Licensee may make a written request to the University to delay submission for publication if, in the Licensee’s
reasonable opinion, such delay is necessary in order to (i) seek patent or similar protection for the Relevant Know-How and Data; and/or (ii) safeguard its valuable proprietary information
and/or trade secrets. A delay imposed on submission for publication as a result of a written request made by the Licensee shall not last longer than is necessary to seek required protection; and therefore shall not exceed [***] from the date of
receipt of the written request to delay submission for publication by the Licensee, although OUI will procure that the University will not unreasonably refuse a request from the Licensee for additional delay in the event that Intellectual Property
Rights would otherwise be lost. If Relevant Know-How and Data that is to be included in any proposed publication comprises of valuable proprietary information and/or trade secrets that are not patentable (or
that it are patentable but maintaining such information as a trade secret is, in Licensee’s reasonable opinion, preferable to patenting it) the Licensee and OUI shall, in good faith, seek to agree upon the steps to be taken to ensure the value
of Relevant Know-How and Data is retained while at the same time trying to enable the University to make some form of agreed publication. Notification of the requirement for delay in submission for publication
must be received by the University within [***] after the receipt of the notice of intention to publish by the Licensee, failing which the University shall be free to assume that the Licensee has no objection to the proposed publication.



  

	3.7	 Where MRC wishes to submit a publication including the Licensed
Know-How, MRC will use all reasonable endeavours to submit such draft publication to the Licensee in writing not less than [***] in advance of the submission for publication. The Licensee may make a written
request to MRC to delay submission for publication if, in the Licensee’s reasonable opinion, such delay is necessary in order to (i) seek patent or similar protection for the Licensed Know-How;
and/or (ii) safeguard its valuable proprietary information and/or trade secrets. A delay imposed on submission for publication as a result of a written request made by the Licensee shall not last longer than is necessary to seek required
protection; and therefore shall not exceed [***] from the date of receipt of the written request to delay submission for publication by the Licensee, although MRC will not unreasonably refuse a request from the Licensee for additional delay in the
event that Intellectual Property Rights would otherwise be lost. If the Licensed Know-How that is to be included in any proposed publication comprises of valuable proprietary information and/or trade secrets
that are not patentable (or that it is patentable but maintaining such information as a trade secret is, in Licensee’s reasonable opinion, preferable to patenting it) the Licensee and MRC shall, in good faith, seek to agree upon the steps to be
taken to ensure the value of the Licensed Know-How is retained while at the same time trying to enable MRC to make some form of agreed publication. Notification of the requirement for delay in submission for
publication must be received by MRC within [***] after the receipt of the notice of intention to publish by the Licensee, failing which MRC shall be free to assume that the Licensee has no objection to the proposed publication.




  
 4 














	3.8	 The Licensors shall not (and OUI undertakes to procure that the University shall not) take any action
(including entering in to any agreement) which is inconsistent with their obligations hereunder or is otherwise conflicting with the Licensee’s rights hereunder. 



 

	3.9	 Where the University, OUI or MRC (or any of their respective employees, officers, students or other
representatives) wants to conduct any study in human volunteers or patients (e.g. a clinical trial) or any study in animals in accordance with Good Laboratory Practice which makes any use of the Licensed Technology, OUI (in the case of itself and/or
the University) or MRC will use reasonable endeavours to notify the Licensee in writing as soon as reasonably practicable, and provide, subject to third-party rights and/or obligations, to the Licensee, in confidence, details of the Compounds that
are the subject of such study and, upon request, a copy of the protocol for such study and such other information as Licensee may reasonably require in order to assess the implications of such study (for example, the relevant investigators’
brochure or investigational medicinal product dossier where applicable). Having regard to the commercial sensitivity of any public disclosure of the identity of the Licensee’s lead Compounds and the potential regulatory implications of the
conduct of studies thereon, OUI and MRC undertake to consider (and to procure that the University and, if relevant, the co-owners of the DM1 Application consider) in good faith any reasonable requests made by
the Licensee to use alternative Compounds nominated by the Licensee in place of the originally specified Compounds, where the use of such alternative Compounds will protect the Licensee’s Confidential Information and/or modify the study
protocol (for example, to reduce dose) without adversely affecting the conduct of the such clinical trial. 


  

	3.10	 Matters pertaining to the Addendum 



 

	3.10.1	 The Addendum shall be annulled with effect from the Effective Date whereupon it shall cease to have any effect
and, for the avoidance of doubt, OUI hereby waives its rights under clause 3.2.2 of the Addendum. 


  

	3.10.2	 OUI confirms that they have not (and OUI confirms that the University has not) granted any right to any person
in or to the DPFS Funded Technology (as defined in the Addendum) whether under clause 3.2.1 of the Addendum or otherwise. 


  

	4.	 FILING AND MAINTENANCE 



 

	4.1	 The Licensee will pay OUI the DM1 Past Patent Costs within [***] of receiving an invoice from OUI.



  

	4.2	 OUI will in consultation with the Licensee and at the Licensee’s cost, prosecute, use all reasonable
endeavours to maintain, and renew the Applications throughout the duration of this agreement. OUI will give all reasonable consideration to the views of the Licensee and will not unreasonably refuse to prosecute, maintain or renew the Applications
provided always that the Licensee agrees to bear the costs of such action according to this clause 4.2. The Licensee will reimburse OUI for all costs, filing fees, lawyers’ and patent agents’ fees, expenses and outgoings of whatever nature
incurred by OUI in the prosecution, maintenance and renewal of any of the Applications (including those incurred in opposition proceedings before the European Patent Office or in ex parte re-examination or
inter partes review proceedings in the United States Patent and Trademark Office (“USPTO”) or any similar proceedings before any patent office challenging the grant or validity of any of the Applications) within [***] of
receiving an invoice from OUI. OUI shall be entitled to make it a condition of any action of OUI under this clause 4.2 that the Licensee provides OUI with sufficient money in advance to cover the costs likely to be incurred in the action.




  
 5 














	4.3	 Where any of the Applications is prosecuted in the USPTO and the Licensee is a small business concern as
defined under the US Small Business Act (15 USC 632) OUI intends to pay reduced USPTO patent fees under US patent law 35 USC 41 (h)(1). The Licensee will notify OUI as soon as reasonably possible if it or a
sub-licensee ceases to be a small business concern as defined under the US Small Business Act (15 USC 632) or becomes aware of any other reason why it would not qualify for reduced USPTO patent fees under US
patent law 35 USC 41(h)(1). 


  

	4.4	 OUI shall procure that its patent agent(s) provide MRC with copies of Applications and Applications office
actions on the same and with an annual update on the status of the Applications in each territory. MRC will grant a power of attorney to patent agent(s) to the extent required to act on MRC’s behalf for filing, prosecuting, maintaining and
renewing the Applications, as requested by OUI or its patent agent(s). 


  

	4.5	 The Licensee shall inform OUI not less than [***] in advance of any national phase filing deadline of the
territories within the scope of the PCT that it wishes to be covered in the national phase of any of the Applications. In the event that the Licensee does not give the required minimum of [***] advance notice OUI shall then be entitled to proceed
with filing the Applications at the Licensee’s cost in whichever territories as it may in its sole discretion decide. 


  

	4.6	 Subject to MRC having the right to take over prosecution and maintenance of that Application in accordance with
clause 4.8, the Licensee shall be entitled to remove any one or more of the countries from the Territory at any time by giving not less than [***] notice to OUI. If the relevant Application is proceeding under the PCT then such notice may not be
given any earlier than the date for commencement of the national phase filing. For the avoidance of doubt the Licensee shall remain liable for the costs mentioned in clause 4.2 that arise or are incurred by OUI during the said notice period in
respect of the countries being removed. 


  

	4.7	 Unless as permitted by clause 4.8, OUI or the Licensee (in the case where OUI has transferred the prosecution
or maintenance of the Applications to the Licensee in accordance with clause 4.8 below) will not abandon or transfer the prosecution or maintenance of any Applications without the prior written consent of MRC, such consent not to be unreasonably
withheld or delayed. 


  

	4.8	 In the event that OUI elects to discontinue the prosecution and/or maintenance of any of the Applications, OUI
shall notify the Licensee of such election in writing (such notice to be given where reasonably possible no less than [***] prior to such patent rights lapsing). The Licensee shall have the right, but not the obligation to take over prosecution and
maintenance of that Application in the joint names of the Licensors. The Licensee shall have [***] from the date of such election in writing to notify OUI that it wishes to take over prosecution and maintenance. If the Licensee elects not to
prosecute or maintain or to abandon any or all of the Applications in any or all of the Major Territories for which it has assumed responsibility pursuant to this clause, the Licensee shall notify MRC of such election in writing (such notice to be
given where reasonably possible no less than [***] prior to such patent rights lapsing). MRC shall have [***] to inform the Licensee (as applicable) that it wishes to assume responsibility for managing and maintaining the Applications in question
and should MRC wish to exploit such Applications on behalf of the parties, the Licensors shall enter into a co-ownership agreement on reasonable terms to be agreed between the Licensors. Immediately following
execution of such co-ownership agreement, such Applications will no longer be governed by this agreement. For the purpose of this agreement, “Major Territories” means [***].



  

	4.9	 OUI and MRC will consider any request by the Licensee for the Licensee to take over the prosecution and
maintenance of the Applications and will not unreasonably refuse to agree to the Licensee taking over the prosecution and maintenance of the Applications. The Licensee shall refrain from submitting any such request when any urgent office action is
pending. OUI and MRC will agree to such take over upon the Licensee’s request where the Licensee can demonstrate to OUI and MRC: 


  

	4.9.1	 it has successfully established internal patent management expertise, and/or engaged with external patent
counsel; 



  
 6 














	4.9.2	 that, during the [***] period immediately preceding the date of Licensee’s request to take over the
prosecution and maintenance of the Applications, there have been no instances of any failure by the Licensee to cooperate reasonably with OUI and MRC, nor any instances of any failure of the Licensee to respond in a timely fashion to any official
communication relating to the prosecution and maintenance of the Applications; and 


  

	4.9.3	 it has sufficient financial resources to manage the Applications which condition shall be deemed met where the
Licensee has of investment monies totaling [***] or more. 


  

	4.10	 On an
Application-by-Application and country-by-country basis, on the date on which OUI and MRC
have agreed to hand over the prosecution and maintenance of the relevant Application to the Licensee (in each case the “Hand Over Date”), the Licensee will, through counsel of its own choosing at its own cost, in accordance
with the provisions of clauses 4.12 to 4.16 below, prosecute (including dealing with any interferences, oppositions, appeals, reissue proceedings and re-examinations), use all reasonable endeavours to
maintain, and renew such Application throughout the duration of this agreement in the relevant country being a Major Territories or such other territories as Licensee may choose. 



 

	4.11	 OUI and MRC shall (and OUI undertakes to procure that the University shall) if requested to do so by Licensee
at Licensee’s cost immediately enter into confirmatory licence agreements (as appropriate) for the purposes of recording any licences granted under this Agreement with such patent offices as Licensee considers appropriate.



  

	4.12	 Following the Handover Date, Licensee shall provide OUI and MRC with: 



 

	 	(a)	 prior notice of any intention to abandon or significantly narrow the scope of any of the claims included in the
Applications prior to filing any application for abandonment or narrowing such claims, in sufficient time to allow review and comment by OUI and MRC (and Licensee will give all reasonable consideration to the views of OUI and MRC thereon) and in any
event at least [***] before such application is made; 


  

	 	(b)	 drafts of any new patent applications that embody any of the Licensed Technology originating from OUI, the
University and/or MRC, prior to filing such applications, in sufficient time to allow review and comment by OUI and MRC (and Licensee will give all reasonable consideration to the views of OUI and MRC thereon); provided, however, Licensee shall not
be obliged to delay the filing of any such patent application where such a delay, in Licensee’s reasonable opinion, could have an adverse commercial effect on Licensee; and 



 

	 	(c)	 copies of all correspondence with patent offices pertaining to prosecution of the Applications;



  

	 	(d)	 copies of all opposition and/or interference proceedings filed against any Application in any Major Territory
and drafts of all substantive responses to be filed by the Licensee in such opposition or interference proceedings or appeals therefrom; and 


  

	 	(e)	 an opportunity to comment on any proposed responses, voluntary amendments and submissions of any kind to be
made to any and all such patent offices in Major Territories; provided, however, the Licensee shall not be obliged to delay the filing of any such response, voluntary amendment or submission if to do so would prejudice its position in relation to
such opposition or interference proceedings. 



  
 7 














	4.13	 Following the Handover Date, Licensee shall procure that its patent agent(s) provide OUI and MRC with an annual
update on the status of the Applications in each territory. OUI and MRC will grant a power of attorney to Licensee’s patent agent(s) to the extent required to act on OUI’s and/or MRC’s behalf for filing, prosecuting, maintaining and
renewing the Applications, as requested by Licensee or its patent agent(s). 


  

	4.14	 Following the Handover Date, Licensee shall inform OUI and MRC not less than [***] in advance of any national
phase filing deadline of the territories within the scope of the PCT that it intends to be covered in the national phase of any of the Applications. 


  

	4.15	 Following the Handover Date, unless as permitted by clause 4.16, the Licensee or OUI (in the case where the
Licensee has transferred the prosecution or maintenance of the Applications to OUI in accordance with clause 4.16 below) will not abandon or transfer the prosecution or maintenance of any Applications without the prior written consent of MRC, such
consent not to be unreasonably withheld or delayed. 


  

	4.16	 Following the Handover Date, in the event that Licensee elects to discontinue the prosecution and/or
maintenance of any of the Applications in one or more territories, or to abandon or significantly narrow the scope of any of the claims included in the Applications, Licensee shall notify OUI of such election in writing (such notice to be given
where reasonably possible no less than [***] prior to such patent rights lapsing). OUI shall have the right, but not the obligation to take over prosecution and maintenance of that Application in the joint names of the Licensors in the relevant
territories. OUI shall have [***] from the date of such election in writing to notify the Licensee that it wishes to take over prosecution and maintenance. If OUI elects not to prosecute or maintain or to abandon any or all of the Applications in
any or all of the Major Territories for which it has assumed responsibility pursuant to this clause, OUI shall notify MRC of such election in writing (such notice to be given where reasonably possible no less than [***] prior to such patent rights
lapsing). MRC shall have [***] to inform the OUI or Licensee (as applicable) that it wishes to assume responsibility for managing and maintaining the Applications in question in the territories in question and should MRC wish to exploit such
Applications on behalf of the parties in such territories, the Licensors shall enter into a co-ownership agreement on reasonable terms to be agreed between the Licensors. Immediately following execution of
such co-ownership agreement, such Applications in the relevant territories will no longer be governed by this agreement. For the purpose of this agreement, “Major Territories” means
[***]. For the avoidance of doubt, the provisions of this clause 4.16 shall not apply in the event of any discontinuation of the prosecution or maintenance of any the Application pursuant to clause 4.8.

misappropriation or infringement) of any rights in the Licensed Technology of which the party becomes aware. 


  

	5.2	 The Licensee has the first right (but is not obliged) to take Legal Action at its own cost in relation to any
misappropriation or infringement of any rights included in the Licensed Technology (excluding the Licensed Know-How). The Licensee must discuss any proposed Legal Action with each of the Licensors prior to the
Legal Action being commenced, and take due account of the legitimate interests of each of the Licensors in the Legal Action it takes provided always that the Licensee may act without further consultation if rights in the Licensed Technology would
otherwise be prejudiced or lost. 



  
 8 














	5.3	 If the Licensee takes Legal Action under clause 5.2, the Licensee will: 



 

	5.3.1	 indemnify and hold each of the Licensors and the University harmless against all costs (including lawyers’
and patent agents’ fees and expenses), claims, demands and liabilities arising out of or consequent upon a Legal Action and will settle any invoice received from OUI and/or MRC in respect of such costs, claims, demands and liabilities within
[***] of receipt); 


  

	5.3.2	 treat any account of profits or damages (including, without limitation, punitive damages) awarded in or paid to
the Licensee under any settlement of the Legal Action for any misappropriation or infringement of any rights included in the Licensed Technology as Net Sales exceeding the Royalty Threshold for the purposes of clause 7, having first for these
purposes deducted from the award or settlement an amount equal to any legal costs incurred by the Licensee in the Legal Action (including any costs incurred by it under clause 5.3.1 above) that are not covered by an award of legal costs; and



  

	5.3.3	 keep each of the Licensors regularly informed of the progress of the Legal Action, including, without
limitation, any claims affecting the scope of the Licensed Technology; provided that the obligations on the Licensee to indemnify in clause 5.3.1 and pay royalties on any account of profits or damages in clause 5.3.2 will not apply to the extent
that the Licensors or either of them or the University is held by a court of competent jurisdiction with no further right of appeal to have licensed rights in the Licensed Technology in breach of this agreement to the third party against whom the
Licensee has brought the Legal Action and upon which the third party has relied to deny infringement in defence of the Legal Action. 


  

	5.4	 Subject to the Licensee’s rights under clause 5.2, OUI shall have the right, but not the obligation, to
take any Legal Action at its own cost in relation to any misappropriation or infringement of any rights included in Licensed Technology (excluding the Licensed Know-How) where: 



 

	5.4.1	 the Licensee has notified each of the Licensors in writing that it does not intend to take any Legal Action in
relation to any misappropriation or infringement of any such rights; or 


  

	5.4.2	 if having received professional advice with regard to any Legal Action within [***] of the notification under
clause 5.1, and consulted with the other parties, the Licensee does not take reasonable steps to act upon an agreed process for dealing with such misappropriation or infringement (which may include, for the avoidance of doubt, seeking a second
opinion in respect of such professional advice) within any timescale agreed between the parties and in any event within [***] of notification under clause 5.1 (in each case requiring agreement in the foregoing, the parties will act reasonably)
provided it shall not settle any action without first consulting with the other parties and taking account of their reasonable observations and requests. 


  

	5.5	 Subject to the Licensee’s rights under clause 5.2 and OUI’s rights under clause 5.4, MRC shall have
the right, but not the obligation, to take any Legal Action at its own cost in relation to any misappropriation or infringement of any rights included in the Licensed Technology (excluding the Licensed
Know-How) where: 


  

	5.5.1	 each of the Licensee and OUI has notified MRC in writing that it does not intend to take any Legal Action in
relation to any misappropriation or infringement of any such rights; or 


  

	5.5.2	 if having received professional advice with regard to any Legal Action within [***] of the notification under
clause 5.1, and consulted with the other parties, neither the Licensee nor OUI takes reasonable steps to act upon agreed process for dealing with such misappropriation or infringement (which may include, for the avoidance of doubt, seeking a second
opinion in respect of such professional advice) within any timescale agreed between the parties and in any event within [***] of notification under clause 5.1 (in each case requiring agreement in the foregoing, the parties will act reasonably),
provided it shall not settle any action without first consulting with the other parties and taking account of their reasonable observations and requests.

	5.6	 If a Licensor takes Legal Action under clause 5.4 or 5.5, that Licensor will: 



 

	5.6.1	 indemnify and hold the other Licensor and the University harmless against all costs (including lawyers’
and patent agents’ fees and expenses), claims, demands and liabilities arising out of or consequent upon a Legal Action and will settle any invoice received from such parties in respect of such costs, claims, demands and liabilities within
[***] of receipt; 


  

	5.6.2	 retain in full any profits or damages (including, without limitation, punitive damages) awarded in or paid

	7.6	 The Licensee will pay to OUI a royalty equal to the Sublicensing Royalty Rate multiplied by any royalties paid
to the Licensee by a sub-licensee (where such royalties paid to the Licensee by a sub-licensee were calculated by reference to net sales of Licensed Products by said sub-licensee), where the Fee Income Royalty Rate is not payable under clause 7.5. 


  

	7.7	 The Restatement Completion Fee, each Milestone Fee and the Exit Fee are

Times as published in London on: 


  

	7.10.1	 the first Business Day of each month during the Quarter just closed; or 



  
 12 














	7.10.2	 for payments under clauses 7.5 and 7.6 only, the first Business Day of the month in which the payment was
received by the Licensee. 


  

	7.11	 Where the Licensee (in respect of payments to OU I) or OU I (in respect of payments to MRC) has to withhold tax
by law, the Licensee or OUI (as applicable) will deduct the tax, pay it to the relevant taxing authority, and supply OUI or MRC (as applicable) with a Certificate of Tax Deduction at the time of payment to OUI or to MRC (as applicable).

quarterly. 


  

	7.13	 If the Licensed Product is of a description covered by the Medicines Access Policy, the Licensee shall adhere

Rate on Net Sales of Licensed Products in respect of the products concerned an amount equal to [***] per cent ([***]%) of the sums actually paid to that third party, up to a maximum amount of [***] percent ([***]%) of the royalties due to OUI.



  

	7.15	 At such time as a Licensed Product that is covered by a Valid Claim of the DM1 Application is first marketed
for the treatment of any trinucleotide repeat disorder, including but not limited to myotonic dystrophy type 1, the Licensee undertakes to negotiate in good faith with the Licensors with a view to agreeing terms consistent with clause 9.1 under
which broad international patient accessibility for such Licensed Products can be assured such that the conditions of commercialisation of the Licensed Products do not constitute a material obstacle to the ability of patients suffering from any
trinucleotide repeat disorders, including but not limited to myotonic dystrophy type 1 to have access to such Licensed Product, taking into account notably any existing and applicable regulatory and reimbursement systems and any other applicable
legal and regulatory regimes on a relevant national, international or regional level, and as the case may be, such as Patient Assistance Program (PAP) (or global equivalents of that program), Compassionate Use Program, or the grant of a conditional
(EU) or accelerated (US) approval for the eligible patients. 


  

	7.16	 Where a Licensed Product is sold as part of a combination product or
co-packaged product (in combination with, or co-packaged with, a product other than another Licensed Product), the Net Sales from the combination product or co-packaged product, for the purposes of determining royalty payments, shall be determined by multiplying the Net Sales of the combination product or co-packaged product,
during the applicable royalty reporting period, by the fraction: 


 A / (A + B), 

where A is the average sale price of the Licensed Product when sold separately in finished form, or if not sold separately, the market price of
the Licensed Product if it were sold separately and B is the average sale price of the other product(s) included in the combination product or co-packaged product when sold separately in finished form, or if
not sold separately, the aggregate market price of the other product(s) if it were sold separately in each case during the applicable royalty reporting period or, if sales of both the Licensed Product and the other product(s) did not occur in such
period, then in the most recent royalty reporting period in which sales of both occurred. In the event that such average sale price cannot be determined for the Licensed Product and any other product(s) included in the combination product, then the
matter shall be referred to an independent expert for determination.

Milestone Fee pursuant to clause 7.18, where OUI shall pay MRC [***] percent ([***]%) of Net Receipts; and 


  

	7.17.2	 any Net Receipts received by OUI in relation to Licensed Products which are covered by a Valid Claim of the DM1

	7.18	 The Licensee will notify OUI and MRC as soon as possible after it or any
sub-licensee achieves any Milestone, and pay to OUI the Milestone Fee in respect of each Milestone within [***] of the date on which each Milestone is achieved by the Licensee or a sub-licensee. The Milestone Fee will be indexed to the RPI and each Milestone will be increased (or decreased, if appropriate) by the percentage change in the RPI between the date of this agreement and the date on
which the Milestone to which it relates is achieved. Each Milestone Fee shall be payable once only in respect of the first achievement of the relevant Milestone even if the Milestone occurs with respect to more than one Licensed Product or in more
than one country.

Licensors for approval and the Licensors shall not unreasonably withhold such approval. If no objections are received within [***] of submission, the revised development plan shall be deemed approved. Any dispute between the parties relating to the
Licensors’ approval of the revised development plan shall be referred to an appropriately qualified independent expert applying the procedure set out in clause 9.4 below. Pending the outcome of any such referral to the Expert, the Licensee
