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,

| | 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.
| | ------ | -------------------------------------------------------------------------------------------------------------------------



|9.12 | The parties agree that [***] of the Hypothetical Licence Fee (the
"Capitalisation Payment") shall become due and payable to SIIL as set out in clauses 9.12, 9.13 and 9.16 of this
Agreement. The Capitalisation Payment shall be split on a pro rata basis into instalments which reflect the value of the
up-front licence fee and the milestones determined by the Expert pursuant to clause 9.11 of this Agreement as a percentage of
the Hypothetical Licence Fee and shall become payable:- (a) in the case of a hypothetical up-front fee, within thirty days of
the date of the expert's determination and, (b) in the case of a hypothetical milestone payment, on the occurrence of
the milestone to which the pro rated instalment relates, or as set out in clause 9.16. The following example illustrates
the operation of this clause 9.12 but should in no way be used by the Expert as indicative of the hypothetical fees
and milestones which would be due to SIIL and/or the quantum of such fees and milestones.
|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Schedule 22



Share of Net Revenues Pursuant to Clauses
6.8 and 9.6



|1. |  | As at the commencement date of the Third Party Agreement, the parties shall refer
for Expert Determination in accordance with schedule 21 size of the global market for EPO and the percentage of the global market
for EPO which is:-
|-- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|1.0 |  | sold in the SIIL Territory as defined prior to the commencement date of the Third
Party Agreement ("A%"); and
|--- |  | -------------------------------------------------------------------------------------------------------------

|1.1 |  | sold in the Lipoxen Territory as defined prior to the commencement date of the Third
Party Agreement (''B%'').
|--- |  | --------------------------------------------------------------------------------------------------------------

|2. |  | Any and all Net Revenue received by Lipoxen pursuant to a Third Party Agreement ("Third
Party Revenue") shall be split according to the percentages determined under paragraphs 1 and/or 2 above. A% of Third Party
Revenue shall be deemed to be Net Revenue for the purposes of clause 9.4.1 of this agreement and B% of Third Party Revenue shall
be deemed to be Net Sales Value received by SIIL for the purposes of clause 9.4.1 of this Agreement.
|-- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|3. |  | By way of example, if on the commencement date of a Third Party Agreement, the parties
agree that the global market for EPO is $10 billion, made up of $2 billion in the SIIL Territory $8 billion in the Lipoxen Territory,
A% would be 20% and B% would be80%.
|-- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4. |  | If Lip oxen PLC and/or Lipoxen Technologies (either separately or together) received
$10 million by way of a milestone payment pursuant to the Third Party Agreement then:-
|-- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4.1 |  | $2 million (20% of$10 million) would be deemed to be Net Sales Value received by SIIL for
                                                                               the                                                                                purposes of clause 9.1 of this Agreement.
                                                                               Lipoxen would be entitled to retain $160,000 of the $2 million, being 8% of
                                                                               $2 million, and would be due to pay the balance of $1,840,000 to SIIL, being the balance of$2 million less $160,000; and
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4.2 |  | $8 million (80% of $10 million) would be deemed to be Net Revenue for the purposes
of clause 9.4.2 of this Agreement. Lipoxen would be entitled to retain $6million and would be due to pay $2 million to
SIIL, being 25% of $8 million.
|--- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|5. |  | Hence in relation to the $10 million milestone payment referred to in paragraph 5above, Lipoxen would in total retain $6,160,000 and would be due to pay $3,840,000 to SIIL.

Price and Payment



|12. |  | SIIL agree that the price for the manufacture and supply
of Supply Products by SIIL to Lipoxen Technologies and/or Customers shall be as set out in Schedule 15 of this Agreement. The
parties acknowledge that a price has not been agreed for all types of PSA which Lipoxen may in the future wish to source from
SHL but SIIL shall use its best endeavours to agree a fair and reasonable price for any types of PSA for which the price is not
set out in this Agreement. SIIL warrant that the price for Monodisperse Oxidised PSA (PSA described in part 2 of Table B in schedule

SIIL is able to obtain in relation to the relevant fo11n of PSA and that this information will be used as a guide to determine
a fair and reasonable price for any types of PSA for which the price is not set out in this Agreement.
