and renew the Applications (including any patent applications filed for an Inventor Improvement) throughout the duration of this agreement.
The Licensors 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 in accordance with this clause
5.2. The Licensee will reimburse the Licensors for all costs, filing fees, lawyers’ and patent agents’ fees, expenses
and outgoings of whatever nature incurred by the Licensors in the prosecution, maintenance and renewal of the Application (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 the Application) within thirty (30) days of receiving an invoice from one of the Licensors. The
Licensors shall be entitled to make it a condition of any action of the Licensors under this clause 5.2 that the Licensee provides

one or more of the countries from the Territory at any time by giving not less than six months’ notice to the Licensors. If any

are incurred by the Licensors during the said notice period in respect of the countries being removed.

 

		5.6	The Licensors and the Licensee will carry
out an annual review of the prosecution of the Applications within thirty (30) days of the end of each Licence Year and after the end
of the second Licence Year. The Licensors will consider with the Licensee at each annual review whether it is appropriate for the Licensee
to take over the prosecution and maintenance of the Applications provided that in all circumstances the Applications will be prosecuted
in the Peoples Republic of China unless OUSST has provided its written consent (such consent not to be unreasonably withheld) for OUI

of such costs, claims, demands and liabilities within thirty (30) days of receipt;

 

		6.3.2	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 for the purposes of clause 8, 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 that are not covered by an award of legal costs; and

                                                                 forty-five (45) days of notification under clause 6.1, provided it shall not

		6.5	Subject to clauses 6.2 and 6.3, if the Licensee takes Legal Action each of the Licensors
will provide such reasonable assistance as requested by the Licensee in relation to such Legal Action at the Licensee’s cost and
authorises the Licensee to join each of the Licensors as a party in any Legal Action where it is a legal requirement for the patent owner
to be a plaintiff in the Legal Action, provided that the Licensee indemnifies each of the Licensors under clause 6.3.1 for the
costs of any legal representation in the Legal Action required by OUI.

that the Licensors shall not suffer any loss or any loss of damages in an infringement action.

 

		13.4	Thesis – This agreement shall not prevent or hinder registered students of the University
from submitting for degrees of the University theses based on the Licensed Technology; or from following the University’s procedures
for examinations and for admission to postgraduate degree status.

is a publicly listed company with a market capitalisation equal to or in excess of [****]
it will be considered to have sufficient financial resources). If either of the Licensors assigns its rights in the Licensed Technology
to any person it shall do so expressly subject to the Licensee’s rights under this agreement.

or representations in agreeing to enter this agreement and waives all claims for breach of any warranty and all claims for any misrepresentation,
(negligent or of any other kind, unless made by OUI or OUSST fraudulently) in relation to any warranty or representation which is not
specifically set out in this agreement. Specifically, but without limitation, this agreement does not impose or imply any obligation on
the Licensors or the University to conduct development work. Any arrangements for such work must be the subject of a separate agreement
between OUSST and/or the University and the Licensee.

 

		13.12	Variation – Any variation of this agreement must be in writing and signed by authorised signatories

any party that has the benefit of clause 13.14.

 

		13.13	Waiver – No failure or delay by either party in enforcing its rights under this agreement,
or at law or in equity will prejudice or restrict those rights. No waiver of any right will operate as a waiver of any other or later
right or breach. Except as stated to the contrary in this agreement, no right, power or remedy conferred on, or reserved to, either party
is exclusive of any other right, power or remedy available to it, and each of those rights, powers, and remedies is cumulative.

Third Parties) Act 1999 to enforce any term of this agreement.

 

     

     

    

 

		13.15	Governing Law – This agreement is governed by English Law, and the parties submit to the
