AGREEMENT:

1. Interpretation

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 and Schedule 2.

2. Grant Of Licence

2.1 In consideration of the payments required to be made under this agreement by the Licensee, OUI hereby grants to the Licensee a licence throughout the Territory under and in respect of the Licensed Technology to develop, have developed, train, have trained, research, have researched, make, have made, import, have imported, use and have used and Market Licensed Products in the Field on and subject to the terms and conditions of this agreement.

2.2 Subject to clause 4, the Licence is (i) exclusive in relation to the Application and the Exclusive Licensed Know-how; and (ii) non-exclusive in respect of all Licensed Know-how that is not Exclusive Licensed Know-how.  Subject to Clauses 4 and 7, OUI retains unrestricted rights to use and license others to use and license the Licensed Technology outside the Field.

2.3 At the execution date of this agreement, OUI will, at OUI’s cost,

a. supply the Licensee with the Licensed Know-how comprising the Tier 1 documents, materials, and specified know-how (information associated with the documents, protocols, and materials) and shall thereafter take reasonable steps to promptly supply the remaining Licensed Know-how including, but not limited to, the Tier 2 documents identified in Schedule 2, provided in each case that

[*] = CONFIDENTIAL TREATMENT REQUESTED

such documents are in the possession of OUI or the University and readily available to be supplied.

b. use reasonable endeavours to facilitate the supply of the samples by the University under the terms of the Material Transfer Agreement.  

2.4 Subject to clause 2.5 below except in relation to sub-licenses to Affiliates, the Licensee may grant sub-licences (through multiple tiers) under the Licence, provided that:

(a) the sub-licensee has obligations to the Licensee commensurate with those which the Licensee has to OUI under this agreement, except where it is not legally possible to include such obligations in the sub-licence; and

(b) promptly following the grant of each sub-licence, the Licensee provides a certified copy of that sub-licence (redacted to exclude the financial terms or commercialisation plans to the extent necessary to reflect any obligations of confidentiality owed to the sub-licensee and any other terms relating to technology or other matters not licensed under or concerning this agreement) to OUI; and

(c) upon termination of the Licence (or part thereof in respect of one or more countries) all sub-licences granted under the Licence (either for the whole territory where the Licence is terminated, or for those countries where the Licence is terminated only in respect of certain countries) shall automatically terminate.

2.5 Licensee shall be entitled to sub-license any of the rights under the Licence through multiple tiers and without restriction save that (i) no sub-licence may be granted to a [*] without Licensor’s prior written consent; and (ii) OUI shall have a right to object to the grant of a sub-licence under the Licence by Licensee to other third parties solely in the following specific circumstances:

2.5.1 OUI may only object in respect of a proposed sub-licensee if, due to the nature of that proposed sub-licensee’s business, the grant of the sub-licence to that entity will, in the reasonable and measured opinion of OUI, have a material detrimental impact on the reputation of the University by its association; and

2.5.2 if the circumstances in Clause 2.5.1 apply, OUI shall only have the right to object provided that it serves written notice of its objection setting out the grounds for its objection within ten (10) days of written notice from Licensee of the identity of the proposed sub-licensee.

2.6 If OUI has objected to the grant of a sub-licence in accordance with Clause 2.5.2, Licensee may either accept that objection and not grant (or terminate) the sub-licence or if it disputes the objection the following shall apply:

2.6.1 OUI shall procure that representatives from OUI and the University shall meet with Licensee within ten (10) days of the objection to enable OUI, Licensee and the University to discuss the proposed sub-licence and the reasons for the perceived risk that an association will have a material detrimental impact on the University’s reputation and, in good faith, seek ways in which to overcome or mitigate such risk to a pragmatic and reasonably acceptable position;

2.6.2 if OUI agrees that the risk is acceptable or OUI and Licensee agree on any conditions to include in a sub-licence to avert or mitigate the risk then Licensee shall be entitled to grant (or maintain) the sub-licence subject to any agreement reached between OUI and Licensee;

2.6.3 if within ten (10) days of the objection, (i) OUI and Licensee are unable to reach an agreement and Licensee still wishes to grant (or maintain) a sub-licence or (ii) representatives of OUI and the University do not or are unable to meet with Licensee; then Licensee shall be entitled to refer the objection to a person nominated by the chairman of the Wellcome Trust to the

[*] = CONFIDENTIAL TREATMENT REQUESTED

determination identified below (the “Appointed Expert”).  The nomination shall be subject to the Appointed Expert agreeing to be so appointed and the terms of that appointment set by the Wellcome Trust.  The costs of the Appointed Expert shall be borne by [*].  The Appointed Expert shall be entitled to consider any information presented to the Appointed Expert by OUI or Licensee (provided that each party shall copy to the other party all information provided to the Appointed Expert at the same time) and any other information that the Appointed Expert may consider relevant.  The Appointed Expert shall make his or her decision as expert and not as arbiter, and the decision of the Appointed Expert shall be final and binding save in the case of manifest error.  If, in the Appointed Expert’s opinion the Appointed Expert considers the grant of a sub-licence to the third party objected to by OUI will, by virtue of the nature of the business of that third-party entity, be materially detrimental to the reputation of the University, then Licensee shall not grant (or shall terminate) such sub-licence.  In all other circumstances, irrespective of any objection by OUI or the University, Licensee shall be entitled to grant (or maintain) the sub-licence without restriction or condition.  OUI and Licensee hereby irrevocably agree, accept and acknowledge that neither the Wellcome Trust, the Chairman of the Wellcome Trust nor the Appointed Expert shall have any liability to OUI or Licensee (or any third party or any other person) by virtue of the provisions of this Clause or exercise of decisions pursuant this Clause, and OUI and Licensee hereby undertake not to make or bring any claim against any of the Wellcome Trust, the Chairman of the Wellcome Trust or the Appointed Expert with respect to performance in connection with the foregoing or this Agreement.

3.5 If the Licence is terminated prior to its expiry, Licensee shall provide reasonable notification to Licensor of Licensee Improvements and Licensor shall have the right, to be exercised within the later of [*] of the date of termination of this agreement or the said notification to OUI, to a non-exclusive licence to use and commercialise the Licensee’s Improvements on fair and reasonable terms to be agreed.

4. Rights Re Non-Commercial Use and Academic Publication

4.1 The Licensee grants OUI an irrevocable, perpetual, royalty-free licence to grant the University and those persons who at any time work or have worked on the Licensed Technology the licence set out in clause 4.2. OUI will request that the University notifies the Licensee if any use of the Licensed Technology in clause 4.2 is made in the Field in accordance with clause 4.2.

4.2 OUI has granted, to the University and those University Personnel who at any time work or have worked on the Licensed Technology a non-transferable, irrevocable, perpetual, royalty-free licence (without the right to sub-licence) to use and publish the Licensed Technology for Non-Commercial Use.

[*] = CONFIDENTIAL TREATMENT REQUESTED

publication be delayed for a period no longer than [*] (or no longer than [*] if agreed by Licensor) from the date of notification if such delay is necessary in order to protect the Licensed Technology.   If no request for delay is received within 30 days of the date of notification, the University will be free to assume that the Licensee has no objection to the proposed publication.

5 Filing and Maintenance

5.1 The Licensee’s contribution to the patent costs of the Application incurred by OUI prior to the parties entering into this agreement is included as part of the Signing Fee.

5.2 OUI shall keep the Licensee promptly and fully informed of the prosecution, status and official correspondence received in connection with the maintenance, prosecution and renewal of the Application.  OUI shall appoint external patent attorneys for the prosecution, maintenance and renewal of the Application in consultation and agreement with the Licensee. The Licensee shall provide its comments on any patent actions that materially affect the Application in a timely manner, giving due consideration to patent office deadlines associated with such actions. OUI will, in consultation with the Licensee, and giving reasonable consideration to the views of the Licensee take all reasonable endeavours to prosecute, maintain, and renew the Application throughout the duration of this Licence Agreement to obtain the scope of protection most reasonably possible having regard to the Licensee’s views in the consultation.  The Licensee will, within thirty (30) Business Days of receiving an invoice from OUI, reimburse OUI for all external lawyers and patent attorney fees costs and disbursements (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) (having regard to the Licensee’s requests during consultations on prosecution) incurred in respect of the prosecution, maintenance or renewal of the Application.

5.3 Where the Application is prosecuted in the USPTO and the Licensee is a small business concern as defined under the US Small Business Act (15USC632) OUI intends to pay reduced USPTO patent fees under US patent law 35USC 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 (15USC632) or becomes aware of any other reason why it would not qualify for reduced USPTO patent fees under US patent law 35USC 41(h)(1).

5.4 The Licensee shall inform OUI not less than [*] in advance of the National Phase filing deadline (noted in Schedule 2) of the territories within the scope of the PCT that it wishes to be covered in the National Phase of the Application but which shall as a minimum include those of the Key Territories (which, in respect of the European territory may be covered by a European patent) where the claimed invention of the original Application is reasonably considered by the Licensee (based on patent attorney advice) to be granted and patentable subject matter pursuant to local patent laws. In the event that the Licensee does not give the advance notice, OUI shall then be entitled to proceed with filing the applications [*] in up to [*] territories (with a European Patent classified as one territory) as it may in its sole discretion decide.  Where notice is given by the Licensee, OUI shall instruct the prosecuting patent attorneys to enter the Application into the National Phase for each identified territory, and Licensee shall only be responsible for the prosecution, maintenance and renewal fees for those notified territories.

5.5 The Licensee shall be entitled to remove any one or more of the countries from the list of territories provided by the Licensee under clause 5.4 at any time by giving not less than [*] notice to OUI.  If the 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 5.2 that arise or are incurred by OUI during the said notice period in respect of the countries being removed.  However, after expiry of the [*] period, if Licensor continues to maintain the prosecution, maintenance or renewal of the

[*] = CONFIDENTIAL TREATMENT REQUESTED

Application in those countries notified by Licensee, such costs shall be at [*] cost and expense.

6. Infringement

6.1 Each party will notify the other in writing of any unauthorised use, misappropriation or infringement of any rights in the Licensed Technology of which the party becomes aware.

6.2 The Licensee has the first right (but is not obliged) to take legal action at its own cost against any unauthorised use, misappropriation or infringement of any rights (including any contractual restrictions) concerning or included in the Licensed Technology in the Field.  The Licensee must discuss any proposed legal action with OUI prior to the legal action being commenced, and take reasonable due account of the legitimate interests of OUI in the action it takes.  OUI hereby agrees to co-operate to the extent reasonably required by the Licensee in the enforcement of such rights and the Licensee shall reimburse to OUI all reasonable external fees, costs and expenses of OUI in connection with such co-operation.

6.3 If the Licensee takes legal action under clause 6.2, the Licensee will:

(a) indemnify and hold OUI 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 such enforcement activities and will settle any invoice received from OUI in respect of such costs, claims, demands and liabilities indemnified hereunder within thirty (30) Business Days of receipt; and

(b) treat any award of profits or damages (including, without limitation, punitive damages) after deduction of all costs (including lawyers’ and patent agents’ fees and expenses that are not recovered from an award of legal costs), claims, demands and liabilities directly arising out of or consequent upon such enforcement activities which were reasonably and properly incurred, as Net Sales for the purposes of clause 8; and

(c) subject to maintaining privilege or observing any confidentiality arrangements or orders, fully and effectively consult with Licensor in a timely manner before taking any material step in the legal action and take all reasonable steps to keep OUI regularly informed of the progress of the legal action, including, without limitation, any claims affecting the scope, enforceability or validity of the Licensed Technology.

6.4 If the Licensee has notified OUI in writing that it does not intend to take any action in relation to the unauthorised use, misappropriation or infringement or the Licensee has not taken any such action within [*] of the notification under clause 6.1, OUI may take such legal action at its own cost.   If OUI takes legal action under clause 6.4, OUI will:

(a) to the extent that there is no breach or impropriety alleged against the Licensee in respect of the matter, not include, reference or name the Licensee in any such action or proceedings (including by way of adding the Licensee as a defendant);

(b) account to Licensee in respect of any award of profits or damages (including, without limitation, punitive damages) after deduction of all costs (including lawyers’ and patent agents’ fees and expenses that are not recovered from an award of legal costs), claims, demands and liabilities directly arising out of or consequent upon such enforcement activities which were reasonably and properly incurred, which Licensee shall treat as Net Sales for the purposes of clause 8; and

(c) subject to maintaining privilege or observing any confidentiality arrangements or orders, fully and effectively consult with Licensee in a timely manner before taking any material step in the legal action and take all reasonable steps to keep the Licensee regularly informed of the progress of the legal action,

[*] = CONFIDENTIAL TREATMENT REQUESTED

including, without limitation, any claims affecting the scope, enforceability or validity of the Licensed Technology.

7. Confidentiality

7.1 Subject to the remaining provisions of clause 7, each party (being a receiving or disclosing party as the case may be) will keep confidential the Confidential Information of the other party and will not publish or supply the Confidential Information to any third party or use it for any purpose, except in accordance with the terms and objectives of this agreement.  Licensor shall be entitled to share Confidential Information of the Licensee with Professor [*], together with professional advisers, in each case subject to all such disclosures being subject to the terms of this clause 7 and OUI being responsible to the Licensee for any action or omission by those persons which would, if committed by OUI, be a breach of this clause 7.

7.2 The Licensee may disclose to sub-licensees of the Licensed Technology such of the Confidential Information of which it consists as is necessary for the exercise of any rights sub-licensed, provided that the Licensee shall ensure that such sub-licensees accept a continuing obligation of confidentiality in the same terms as this clause, and shall use its reasonable endeavours to procure third party enforcement rights for the benefit of OUI, before the Licensee makes any disclosure of the Confidential Information, and where third party enforcement rights for the benefit of OUI are not procured the Licensee will be responsible for any action or omission by the sub-licensee which would, if committed by the Licensee, be a breach of this clause 7. Additionally, Licensee may disclose Confidential Information to its professional advisors, financiers, investors, consultants, employees, directors, officers, potential and actual investors, acquirers and licensees subject to such persons accepting an obligation of confidentiality and the Licensee being responsible for any action or omission by such person(s) which would, if committed by the Licensee, be a breach of this clause 7.

7.3 Licensor shall keep confidential, and use reasonable endeavours to procure the University, any academic institution and individuals licensed pursuant to clause 4.1, shall keep confidential and not use the Licensed Technology other than as expressly permitted under clause 4.  The exceptions to confidentiality under clause 7.4 below shall not apply to the restrictions under this clause 7.3 in respect of the Licensed Technology.  The restrictions under this clause 7.3 in respect of the Licensed Technology shall not apply to information that is or becomes public (other than by publication after the date of this agreement by Licensor or any Academic Licensee(s)) or which Licensee approves (in writing) may be made public.  The foregoing shall not affect or release OUI from its obligations under Clause 4.2.1 or 7.1.

(e) is approved for release in writing by an authorised representative of the disclosing party.

7.5 The receiving party shall not be in breach of its obligations under clause 7.1 to the extent it makes a disclosure of the disclosing party's Confidential Information where

[*] = CONFIDENTIAL TREATMENT REQUESTED

and to the extent such disclosure is required to be made by mandatory law.  In such circumstances, the receiving party shall, so far as is practicable and permitted by law,

7.6 notify the disclosing party prior to making such disclosure and co-operate with the disclosing party to assist it in seeking confidential treatment of such Confidential Information required to be disclosed.

8. Royalties and other Payments

Signing Fee

8.1 Licensor will invoice the Licensee for the Signing Fee shortly after the Effective Date and the Licensee must settle the invoice within thirty (30) Business Days of receipt of the same.

Royalties

8.2 In respect of any Quarterly reporting period for which Net Sales and royalties are required to be reported by the Licensee pursuant to clause 10.2, the Licensee will (subject to Clauses 8.13 and 8.14) pay to OUI a royalty equal to the Royalty Rate on all those Net Sales made during that Quarterly reporting period, on a country by country basis, where during each of those Quarterly reporting periods any one or more of the following circumstances have prevailed with respect to such country during that Quarter:  

8.2.1 the Application continues to be in force or subsisting in such country;

8.2.2 the Licensee has Market Exclusivity throughout the world;

8.2.3 the Licensee has Market Exclusivity throughout the Region within which the particular country exists; or

8.2.4 the Licensee has Market Exclusivity in the country;

and where those circumstances do not prevail (“Lost Exclusivity”) sales of such Licensed Product in such country for that particular Quarter under the Licence shall be deemed to have been pursuant to a fully paid up, royalty free, licence and right, and no payments under this Clause 8.2 for or in respect of such Licensed Product in such country shall be due in that Quarter.

8.3 In the event that the royalties paid to OUI under clause 8.2 do not amount to at least the Annual Maintenance Fee, the Licensee must make up the difference between the royalties paid under clause 8.2 and the Annual Maintenance Fee in each Licence Year where an Annual Maintenance Fee applies.  The Licensee will also pay to OUI a royalty equal to the Royalty Rate on any sum received from a sub-licensee paid by the sub-licensee to make up the difference between royalties paid on Net Sales and any minimum sum payable by that sub-licensee to the Licensee.

Fee Income Royalty Rate

8.4 The Licensee will pay to OUI a royalty equal to the Fee Income Royalty Rate on all up-front, milestone and other one-off payments (other than payments made solely in relation to research provided by the Licensee) received by the Licensee under or in connection with the grant of or exploitation of Licensed Technology under all sub-licences under the Licence to the extent such monies are concerned with the Licensed Technology and are not treated as Net Sales.  Royalties due under this clause will be paid once in respect of monies received and not each time the Licensed Technology is used.  The Licensee will pay each such royalty in accordance with clause 10 at the end of the Quarter in which the monies were received.

Milestones

8.5 Subject to clause 8.14, the Licensee will notify OUI as soon as possible after it or any sub-licensee achieves any Milestone, and pay to OUI the Milestone Fee in respect of

[*] = CONFIDENTIAL TREATMENT REQUESTED

each Milestone within thirty (30) Business Days of the date on which each Milestone is achieved by the Licensee or a sub-licensee.

Payment Principles

8.6 Without prejudice to any financial remedy for breach subject to the cap on liability set out in this agreement, the Signing Fee and the Milestone Fees are non-refundable and will not be considered as an advance payment on royalties payable under clause 8.3.  

8.7 Should the Licensee receive any non-monetary consideration when Marketing Licensed Products, Net Sales shall, subject to clause 8.3, be calculated by reference to the fair market value of such non-monetary consideration. The Licensee must not accept non-monetary consideration exceeding [*] in any calendar year without the prior consent of Licensor not to be unreasonably withheld.

Miscellaneous Payment Provisions

8.8 The Licensee will make all payments in pounds sterling or any currency replacing pounds sterling in its entirety.

8.9 For the purposes of calculating any amount payable by the Licensee to OUI in a currency other than pounds sterling (or replacement currency), the Licensee shall apply the exchange rate quoted by the Financial Times as published in London on the first Business Day of the last month of the Quarter just closed.

8.10 Where the Licensee has to withhold tax by law, the Licensee will deduct the tax, pay it to the relevant taxing authority, and supply OUI with a Certificate of Tax Deduction at the time of payment to OUI.

8.11 In the event that full payment of any amount due from the Licensee to OUI under this agreement is not made by any of the dates stipulated, the Licensee shall be liable to pay interest on the amount unpaid at the rate of [*] over the base rate for the time being of the Bank of England. Such interest shall accrue on a daily basis from the date when payment was due until the date of actual payment of the overdue amount, whether before or after judgment, and shall be compounded quarterly.  

8.12 If the Licensed Product is of a description covered by the Medicines Access Policy, the Licensee shall adhere to the requirements of the Medicines Access Policy.

Royalty Stack

8.13 If the Licensee has to pay royalties to a third party (other than an Affiliate), for the right to make, have made, use or Market a Licensed Product, under a licence of Intellectual Property Rights without which the Licensed Technology cannot lawfully be exploited, then the Licensee will be entitled to deduct from all payments due to OUI under clause 8.2 in respect of the products concerned an amount equal to [*] of the royalties actually paid to that third party, up to a maximum amount of [*] of the royalties due to OUI under clause 8.3.

Avoiding Double Royalties

8.14 The parties acknowledge that they are subject to the Original Agreement, this Agreement and the Further Licences (collectively with the Original Agreement, the “OUI Licences”).  It is intended that each OUI Licence will only cover a distinct and separate product, process and technique and that there shouldn’t be royalties due under other of the OUI Licences in respect of any of the same product, process or technique sold or deployed by Licensee (or its sublicensees). However, in the event that any product, process or technique Marketed, sold or deployed by Licensee (or any sublicensees) in a single therapeutic field triggers a payment under more than one of the OUI Licences, then royalties payable under each of the relevant Isis Licences will be reduced, on a licence by licence basis, to [*] of the sum that is payable under each of the OUI Licences, provided that the aggregate sum of royalties payable under each of the relevant OUI Licences following the reduction to [*] of the original royalty rates thereunder for such product, process or technique Marketed, sold or deployed shall, in no event, be less than [*] of the single royalty that would be payable under the one relevant OUI Licence that bears the highest royalty rate under which a

[*] = CONFIDENTIAL TREATMENT REQUESTED

royalty is payable for such product, process or technique.  Furthermore, to the extent any Licensed Product under this licence is Marketed or administered using any of the surgical techniques and/or protocols within the definition of Licensed Technology under the Original Agreement, provided that OUI does not control any patent (pending or granted) claiming such surgical techniques and/or protocols (which would be infringed by use of the same in Marketing or administering the Licensed Product) in the country of sale of the Licensed Product, no royalty shall be triggered or payable under the Original Agreement or any of the other OUI Licences for such use.

9. Development Obligations

9.1 The Licensee shall use reasonable endeavours to develop, exploit and Market the Licensed Product in accordance with the Development Plan.

9.2 If the Licensee proposes to make a material amendment to the Development Plan, it shall as soon as practicable inform OUI giving sufficient details and provide OUI with such additional information relevant to those material amendments as OUI may reasonably request. OUI shall approve the Licensee’s material amendments to the Development Plan provided that those amendments are reasonable and reflect the efforts reasonably required of a prudent drug development company (of equivalent resource as the Licensee) having regard to, without limitation, regulatory and scientific guidance from regulatory authorities and industry leaders.  For the avoidance of doubt, upon the Licensee receiving OUI’s approval the revised development plan shall become the Development Plan and any non-material amendments shall be deemed to have amended the Development Plan without requiring OUI’s consent.

9.3 Without prejudice to Licensee’s obligations under clause 9.1 and 9.2 above, the Licensor shall, subject to clause 9.4, have the right to terminate the Licence on a country by country basis if:

9.3.1 with respect to a country within the Major Market, by the [*] the Licensed Product has not been Exploited in that country; or,

9.3.2 in respect of a country within the Secondary Market, by the [*], the Licensed Product has not been Exploited in that country in the Secondary Market.

9.4 The right of OUI to terminate the Licence in respect of a country under clause 9.3 is subject to:

9.4.1 Licensor serving a written notice on Licensee identifying the country or countries in respect of which it is seeking to exercise its rights under clause 9.3; and,

9.4.2 Licensee has not begun Exploitation in such country or countries within [*] of the notice served under clause 9.4.1.

10. Royalty Reports and Audit

10.1 The Licensee will provide OUI with a report at least once in every [*] outlining in reasonable detail having regard to the Development Plan the activities and achievements in its development of the Licensed Technology in order to facilitate its commercial exploitation, and in the development of potential Licensed Products.

10.2 The Licensee will provide OUI with a royalty report within [*] after the close of each Quarter of the Licence Year for each Licensed Product Marketed by the Licensee and its sub-licensees in that Quarter.  Each Royalty Report will:

(a) set out the Net Sales of each Licensed Product Marketed by the Licensee including the total gross selling price of each Licensed Product Marketed by the Licensee and the quantity or total number of units of each Licensed Product Marketed by the Licensee;

(b) provide a calculation of the royalties due including details of all relevant currency conversions made;

[*] = CONFIDENTIAL TREATMENT REQUESTED

(c) provide a statement showing whether or not aggregate Net Sales due exceed [*], and if so by how much until payments due in respect of Licensed Products under clause 8.8 cease to be payable;

(d) set out details of payments received by the Licensee to which the Fee Income Royalty Rate applies and provide a calculation of the royalties due from the Licensee to be paid at the Fee Income Royalty Rate;

(e) set out details of any deductions made to calculate the Net Sales;

(f) set out the steps taken during the Licence Year to promote and market Licensed Products;

(g) provide a statement showing whether or not royalties due exceed the Annual Maintenance Fee and, if so, by how much; and

(h) set out details of any deductions made under clause 8.13 and 8.14.

The Licensee must pay OUI the royalties due in respect of the Quarter just closed at the same time as the Licensee delivers the Royalty Report.

10.3 The Licensee will also deliver to OUI a periodic report from the Licensee providing data in Licensee's possession (in outline form) to give a reasonable indication or estimate of the actual or expected market share of the Licensee and its sub-licensees and will notify OUI in the event that its market share does or is expected to breach the limits set out in the 2014 Commission Regulation 316/2014 Technology Transfer Block Exemption Regulation and Guidelines in Commission Communication 2014/c 89/03 and any successor regulation. Such report shall be deemed the Confidential Information of the Licensee.  Before the first commercial sale of a Licensed Product the Licensee shall provide this report [*].  From then onwards, the report shall be delivered [*]. This obligation is not intended to place a significant additional financial or administrative burden on the Licensee.

10.4 If a Licensed Product Marketed by the Licensee is re-Marketed by an Affiliate or an entity over which the Licensee exercises Control, the royalty on each such Licensed Product will be calculated on the highest of the prices at which it is Marketed or re-Marketed.

10.5 The Licensee must keep complete and accurate accounts of all Licensed Products manufactured, used or Marketed by the Licensee in each Licence Year for at least [*].  OUI may, through an independent certified accountant appointed by OUI (“the Auditor”), audit all such accounts on at least [*] written notice no more than [*] for the purpose of determining the accuracy of the Royalty Reports and payments.  The Auditor shall be:

10.5.1 permitted by the Licensee to enter the Licensee's principal place of business upon reasonable notice to inspect such records and accounts;

11. Duration and Termination

11.1 This agreement will take effect on the date of signature. Subject to the possibility of earlier termination under the following provisions of this clause 11, and subject to the possibility of an extension to the term by mutual agreement, this agreement shall continue in force until and expire upon the Licensee’s written election when none of the following circumstances exist for a consecutive period of 12 months:

11.1.1 the Application continues to be in force or subsisting in any country;

11.1.2 the Licensee has Market Exclusivity throughout the world;

11.1.3 the Licensee has Market Exclusivity throughout any Region; or

11.1.4 the Licensee has Market Exclusivity in any country.

Notwithstanding the foregoing, this agreement will expire in its entirety on the twentieth (20) anniversary of the Effective Date.

Upon expiry of this agreement in accordance with the foregoing, Licensee's Licence shall automatically convert to a fully paid up, royalty free, licence in perpetuity without restriction or control over its sub-licensing or assignment.

11.2 If either party commits a material breach of this agreement, and the breach is not remediable or (being remediable) is not remedied within a period allowed by notice given by the other party in writing calling on the party in breach to effect such remedy (such period being not less than sixty (60) days), the other party may terminate this agreement by written notice having immediate effect.  It is accepted that any delay in fulfilling an obligation under this agreement will be deemed capable of being remediable by fulfilment of that obligation within the relevant notice period notwithstanding the fact such obligation has been delayed or performed late.

11.3 The Licensee may terminate this agreement for any reason at any time on or after the third anniversary of the Effective Date on two (2) months’ written notice whereupon the Licensee shall bring all sub-licences to an end on the same date.  Any such termination shall not absolve the Licensee of its obligation to accrue and pay royalties and other payments under the provisions of clause 8 in respect of the period prior to termination. The Licensee’s right to give two (2) months’ written notice to terminate for any reason under this clause will arise from the first anniversary of the Effective Date where the parties acting reasonably and in good faith have agreed in writing that the Licensed Product is unlikely to be commercially or scientifically viable as a result of scientific or technical data or information becoming available from the performance of the Development Plan that was not available as at the Effective Date.

11.4 OUI may terminate this agreement:

(a) by written notice if the Licensee has a petition presented for its winding-up (which is not set aside within ninety (90) Business Days of its filing), or passes a resolution for voluntary winding-up otherwise than for the purposes of a bona fide amalgamation or reconstruction, or has a receiver or administrative receiver appointed of all or any part of its assets (which appointment is not set aside within ninety (90) Business Days of the appointment);

(b) on thirty (30) days' written notice if the Licensee opposes or challenges the validity of the Application before a patent office or court.

11.5 On termination or expiration of this agreement, for whatever reason, the Licensee:

(a) other than on expiry of this Agreement, must bring all sub-licences it has granted to an end on the same date; and

(b) shall pay to OUI all outstanding royalties and other sums properly due under this agreement up to the date of termination or expiry; and

(c) shall provide OUI with details of the stocks of Licensed Products held at the point of termination;

[*] = CONFIDENTIAL TREATMENT REQUESTED

(d) shall (save as permitted under clause 11.1 or elsewhere in this agreement) cease to have any licence to the Licensed Technology; and

(e) other than on expiry of this agreement, must [*], destroy all Licensed Products in its possession unless otherwise agreed by OUI (acting reasonably).

11.6 Termination of this agreement, whether for breach of this agreement (excluding breach by Licensor) or otherwise, shall not absolve the Licensee of its obligation to accrue and pay royalties under the provisions of clause 8 for the duration of any notice period and in respect of any dealings in Licensed Products permitted by clause 10.4.

11.7 Clauses 3.5, 4.1, 6.3, 6.4, 11.1 (last paragraph), 11.5, 11.6, 11.7, 11.8, 12, 13.4, 13.6, 13.9,13.11, 13.13 and 13.14 will survive the termination or expiration of this agreement, for whatever reason, indefinitely.  

11.8 Clauses 7 and 10.5 will survive the termination or expiration of this agreement, for whatever reason, for a period of six (6) years.

12. Warranties, Representations and Liability
