SIILs Option to Capitalise its Rights



|9.8 | The parties agree that at any time after the commencement by Lipoxen PLC and/or Lipoxen Technologies of a Phase IIa clinical trial in relation to a Lipoxen Product but before the commencement of a Phase IIb clinical
trial by Lipoxen Technologies and/or Lipoxen PLC relating to a Lipoxen Product (the Option Period), SIIL shall be entitled to serve written notice on Lipoxen Technologies requiring Lipoxen PLC to capitalise SIILs rights under
clause 9.4 in accordance with the provisions set out in clauses 9.9 to 9.14 below. Lipoxen shall keep SIIL fully informed in respect of the status of the clinical trials referred to in this clause 9.8 so that SIIL has sufficient time to exercise its
option of capitalisation as envisaged herein. Commencement of a clinical trial for this purpose shall mean the actual administration of the PSA EPO doses to humans admitted to the relevant clinical trial.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



28



---

|9.9 | Any notice served by SIIL pursuant to clause 9.8 (the Option Notice) must be received by Lipoxen PLC during the Option Period. If Lipoxen does not receive a notice from SIIL during the Option Period then
SIILs right under clause 9.8 shall expire.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9.10 | If within ninety (90) days of receipt of the Option Notice Lipoxen enters into a licence agreement with a Sub-licensee in relation to all of the Lipoxen Territory, SIILs rights under clause 9.8 shall expire
and no further action shall be taken by either party pursuant to clauses 9.12 to 9.15 below and in such case clause 9.4.2 shall be applied [***]. If Lipoxen does not enter into a licence agreement with a Sub-licensee in the ninety day period, the
parties agree that the procedure set out in clauses 9.11 to 9.15 shall apply.
|---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9.11 | The parties shall be entitled to appoint an expert in accordance with the procedure set out in Schedule 21 of this Agreement, the cost of which shall be borne entirely by SIIL, to determine the hypothetical value that
would have been achieved by Lipoxen if, on the date the expert issues his opinion, Lipoxen had granted a third party an exclusive licence in the entire Lipoxen Territory of Lipoxens rights in relation to PSA EPO. The expert appointed pursuant
to this clause 9.11 shall be required to assess the value of the exclusive licence based on market practice and in terms of, and by apportioning the hypothetical consideration due to Lipoxen between, up-front licence fees to be paid on signature of
the hypothetical licence agreement and milestones payable on the achievement of clinical development and regulatory approval of Lipoxen Products (the Hypothetical Licence Fee). The parties agree that for the purposes of this clause 9.11,
the expert shall not be entitled to attribute any value to, and shall ignore for the purposes of determining the Hypothetical Licence Fee:-
|---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.11.1 | any hypothetical consideration that might be due to Lipoxen after regulatory approval of a Lipoxen Product, for example milestones due on the achievement of any commercial milestones such as first sale of a Lipoxen
Product; and
| | ------ | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.11.2 | any hypothetical royalties that might become due to Lipoxen on sale of Lipoxen Products by the hypothetical sub-licensee.

|9.16 | The parties agree that, following a determination by the expert in accordance with clause 9.11, if Lipoxen thereafter successfully completes a phase II clinical trial in relation to a Lipoxen Product, Lipoxen shall use
Diligent and Reasonable Efforts to:- (a) commence a phase III clinical trial in relation to the Lipoxen Product; or (b) out-licence its rights in relation to the Lipoxen Product to a third party. If at any time after expiry of
the eighteen month period following completion of a successful phase II clinical trial in relation to a Lipoxen Product, SIIL can prove that Lipoxen has not fulfilled its obligation to use Diligent and Reasonable Efforts to achieve the objective
described in this clause 9.16, SIILs only remedy under this clause 9.16 shall be, by service of thirty days (30) notice in writing to Lipoxen, to terminate the licence granted to Lipoxen under clause 7.1. In the event to termination of by

support the commencement of an EMEA or FDA regulated phase III clinical trial in relation to the Lipoxen Product without any objections being raised by the relevant regulatory authority; and
| | ------ | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.16.4 | Diligent and Reasonable Efforts shall mean exerting such effort and employing such resources as would normally be exerted or employed by a reasonable third party for a product of similar market potential at
a similar state of its product life, taking into account the competitiveness of the relevant marketplace, the proprietary and development positions of third parties, the regulatory structure involved, and the profitability of the product, when
utilising sound and reasonable scientific, business and medical practice and judgment in order to develop a product in a timely manner and maximise the economic return to the parties form its commercialization.
