in respect of sales of Licensed Products […***…] percent ([…***…]%) of Net Sales for that portion of aggregate Net Sales of those Licensed Products in the Territory during such Calendar Year that equal or exceed
USD$[…***…] ([…***…] United States Dollars) but are less than USD$[…***…] ([…***…] United States Dollars) (“Tier 2”); and

7.2.3

in respect of sales of Licensed Products […***…] percent ([…***…]%) of Net Sales for that portion of aggregate Net Sales of those Licensed Products in the Territory during such Calendar Year that equal or exceed

7.3	Combination Products. With respect to Combination Products, the Net Sales used for the calculation of the royalties under Section 7.2 shall be determined as follows:

A X Net Sales of the Combination Product, where:

A+B

A =

standard sales price of the Licensed Product, containing a comparable amount of Compound as the sole active ingredient as the Combination Product in question, in the given country.

B =

standard sales price of the ready-for-sale form of a product, containing a comparable amount of the other therapeutically active ingredient(s) that is contained in the Combination Product in question, in the given country.

***Confidential Treatment Requested

In the event, however, that if, in a specific country, (a) the other therapeutically active ingredient(s) in such Combination Product is not sold separately in such country, Net Sales shall be adjusted by multiplying actual Net Sales of such Combination Product by the fraction A/C, where C is the standard sales price in such country of such Combination Product, and (b) if a Product containing such compound(s) is not sold separately, Net Sales shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction (C-B)/C, where B is the standard sales price in such country of the other therapeutically active ingredient(s) in the Combination Product and C is the standard sales price in such country of the Combination Product. The standard sales price for the Product containing such compound(s) and for each other active ingredient shall be for a quantity comparable to that used in such Combination Product and of the same class, purity and potency.

If, in a specific country, the foregoing calculations do not fairly represent the value of the various active ingredients included in a Combination Product, the allocation of Net Sales for such Combination Product shall be negotiated by the Parties in good faith comparable to such Product or such other active ingredients, as applicable.

If, after good faith negotiations the Parties cannot agree on the appropriate allocation of Net Sales for such a Combination Product in any given country, then either Party shall have the right to refer such dispute to an independent third party who has had experience in a Major Market pricing and reimbursement authority and who is acceptable to both Parties, (agreement not to be unreasonably withheld or delayed by either Party).

(i)

USD$[…***…] ([…***…] United States Dollars) when cumulative Net Sales across all Licensed Products throughout the Territory exceed USD$[…***…] ([…***…] United States Dollars) for the first time.

(ii)

USD$[…***…] ([…***…] United States Dollars) when cumulative Net Sales across all Licensed Products throughout the Territory exceed

***Confidential Treatment Requested

USD$[…***…] ([…***…] United States Dollars) for the first time.

(iii)

The sales related payments shall be paid at the end of the Calendar Quarter in which the relevant Net Sales threshold was achieved at the same time as Flexion pays the royalties due for that Calendar Quarter.

The sales related payments set out above are subject to increase in accordance with the terms of Section 17 below (Potential Third Party Rights).

7.5	Reduction of Royalty.

In the event that, or from and after the date on which, (a) […***…] exists in a country, and (b) […***…] exists in such country, the royalty rate payable to AstraZeneca by Flexion under Section 7.2 with respect to Net Sales of such Licensed Product in such country, shall be […***…]. Any royalties owed to AstraZeneca after such a reduction in the royalty rate shall be compensation for Flexion’s use of the Licensed Know-How in accordance with Section 3.3.

7.6

Royalty Term. Flexion’s obligation to pay royalties shall commence, on a country-by-country basis, with respect to each separate Licensed Product, on the date of First Commercial Sale of such Licensed Product in such country. The obligation shall expire, on a country-by-country basis, with respect to each separate Licensed Product on the later to occur of: (a) the twelfth (12th) anniversary of the First Commercial Sale of such Licensed Product in such country, and (b) such time as there is no longer (i) any Valid Claim of a Licensed Patent that claims or covers the Exploitation of such Licensed Product in such country, and (ii) any Data Exclusivity with respect to such Licensed Product in such country.

7.7	Sales Subject to Royalties. Sales between Flexion, its Affiliates and Sublicensees shall not be subject to royalties hereunder. Royalties shall be calculated on Flexion’s,

***Confidential Treatment Requested

its Affiliates’ and its Sublicensees’ sale of the Licensed Products to a Third Party. Royalties shall be payable only once for any given batch of the Licensed Products. For purposes of determining Net Sales, the Licensed Product shall be deemed to be sold when shipped and a “sale” shall not include, and no royalties shall be payable on, transfers of Licensed Products that are used as samples or in clinical trials or other transfers or dispositions for charitable, promotional, pre-clinical, clinical, regulatory or governmental purposes.

7.8

Royalty Payments. The royalties shall be calculated quarterly as of the last day of March, June, September and December respectively, for the Calendar Quarter ending on that date. Flexion shall pay the royalties in conjunction with the delivery of a written report to AstraZeneca within sixty (60) days after the end of each Calendar Quarter that shows, with respect to each country and each Licensed Product, the sales volume, gross sales amount and Net Sales of the Licensed Products during such Calendar Quarter.

[…***…] request so joins such legal action, […***…] may be represented by counsel of its own choosing, but […***…] shall not be subject to […***…] obligation to indemnify hereunder.

In the event […***…] fails within forty-five (45) days following notice of such infringement, or earlier notifies […***…] in writing of its intent not, to take commercially appropriate steps to remove any infringement of any Licensed Patent, then,

17	Potential Third Party Rights

***Confidential Treatment Requested

18.2

Termination for Breach. In the event that either Party (the “Breaching Party”) shall be in material default in the performance of any of its obligations under this Agreement, in addition to any other right and remedy the other Party (the “Complaining Party”) may have, the Complaining Party may terminate this Agreement in its entirety or with respect to the country or countries to which such material default applies by sixty (60) days prior written notice (the “Notice Period”) to the Breaching Party, specifying the breach and its claim of right to terminate, provided always that the termination shall not become effective at the end of the Notice Period if the Breaching Party cures the breach complained about during the Notice Period (or, if such default cannot be cured within such sixty (60)-day period, if the Breaching Party commences actions to cure such default within the Notice Period and thereafter diligently continues such actions, provided that such default is cured within one hundred and eighty (180) days after the receipt of such notice), except in the case of a payment default, as to which the Breaching Party shall have only a thirty (30)-day cure period; provided further, that if Flexion is in default with respect to its obligations under Section 6.3 in […***…] then AstraZeneca shall have the right to terminate this Agreement with respect to […***…]. A termination notice may not be given for a dispute relating to the amount of royalties owed to AstraZeneca provided that the Parties are seeking to remedy the dispute in compliance with Section 7.9.3 of this Agreement.

18.5	Territorial Effect of a Termination Notice.

18.5.1

In case of termination by Flexion without cause pursuant to Section 18.4 (Termination by Flexion) such termination notice may be made with respect to one country or several specific countries as determined by Flexion (the “Affected Countries”). In the case of any termination notice for breach pursuant to Section 18.2 (Termination for Breach) if the breach of the other Party relates to or takes effect only in certain countries (the “Affected Countries”), such termination notice may only be given with respect to such Affected Countries and must state the Affected Countries. The Affected Countries or all countries of the Territory, as the case may be and as determined by the Party giving termination notice under Section 18.2 or Section 18.4, as the case may be, shall hereafter be referred to as the “Applicable Territory”.

18.5.2

In case of any termination notice for breach pursuant to Section 18.2 (Termination for Breach) by either Party, such termination may be made with respect to the entirety of this Agreement only, if the breach of the other Party relates to or takes effect in at least two or more countries of the Territory and/or affects this Agreement in a global manner, in which case the termination notice must state that the termination shall affect this Agreement in its entirety.

***Confidential Treatment Requested

18.5.3

In the event that a Party is entitled to provide termination notice under Section 18.2 (Termination for Breach) related to this Agreement in its entirety, but the breach affects certain countries of the Territory only, then such Party may at its discretion select and specify in the termination notice the Affected Countries in which such termination notice shall take effect.

18.5.4

For the avoidance of doubt and notwithstanding the above, if a breach by Flexion relates to or takes effect in
[…***…], then AstraZeneca shall have the right to designate […***…] in its notice of breach for the purposes of determining the Applicable Territory.

18.6	Consequences of Termination.

Upon termination by Flexion in accordance with Section 18.2 (Termination for Breach), Section 18.8 (Termination for Insolvency or Bankruptcy) or Section 19.4 (Force Majeure) of this Agreement, all licences and other rights granted by AstraZeneca to Flexion in the Territory, shall terminate and revert to AstraZeneca.

Notwithstanding anything to the contrary in this Section 18.6.2, upon termination of this Agreement by Flexion in accordance with Section 18.4 (Termination by Flexion) based on Flexion’s determination that the commercial viability of Compound(s) or Licensed Products has adversely changed for any reason beyond Flexion’s control, including without limitation because of any issues related to Patents or Intellectual Property Rights of Third Parties or Third Party Licences, then a licence under the Flexion Product Data and Grant-Back Patents (if any) shall be granted on a […***…] basis only with […***…] to be agreed upon by the Parties.

18.6.4

18.10

Consequences of AstraZeneca Breach of Section 3.1.

18.10.1

If, in accordance with the dispute resolution procedure set out in Section 24.3, AstraZeneca is found to have been in breach of the licence grant set out in Section 3.1 of this Agreement, namely that it is found to have granted rights to the Licensed Patents and/or the Exclusively Licensed Know-How to a Third Party in breach of this Agreement; and Flexion has not exercised its right to terminate this Agreement, then Flexion shall have the right either (a) to claim damages in respect of the loss suffered by it as a result of such breach; or (b) to claim a penalty from AstraZeneca in lieu of damages, such penalty to be calculated in accordance with the following provisions:

(i)

If the breach is discovered by Flexion at any time after the Effective Date but prior to […***…] then all future development, filing and approval milestone payments due to AstraZeneca under Section 7.1 after the discovery of such breach shall be […***…];

(ii)

If the breach is discovered by Flexion after […***…] but prior to […***…] then all future development, filing and approval milestone payments due to AstraZeneca under Section 7.1 after the discovery of such breach shall be […***…];

(iii)

If the breach is discovered by Flexion after […***…] and prior to […***…]

***Confidential Treatment Requested

[…***…] then all future development, filing and approval milestone payments due to AstraZeneca under Section 7.1 after the discovery of such breach shall be […***…] and the royalties payable to AstraZeneca under Section 7.2 after the discovery and notification of such breach shall be […***…];

(iv)

If the breach is discovered by Flexion after […***…] but before […***…] then all future development, filing and approval milestone payments due to AstraZeneca under Section 7.1 after the discovery of such breach shall be […***…] and the royalties and sales related payments payable to AstraZeneca under Sections 7.2 and 7.4 after the discovery of such breach shall be […***…];

provided that in each case Flexion gives AstraZeneca notice of the discovery of the breach promptly after having gained sufficiently detailed knowledge of such breach allowing Flexion to serve a notice of breach under Section 18.2 and giving AstraZeneca the opportunity to cure the breach in accordance with the provisions of Section 18.2 above, and provided further that AstraZeneca has failed to cure the breach so notified in accordance with the timescales set out in that section. Flexion undertakes that it will promptly investigate any suspected breach by AstraZeneca and will, notwithstanding that it may not have gained sufficient evidence formally to allege a breach of the Agreement, notify AstraZeneca promptly if any facts or matters come to its attention which lead it to believe that AstraZeneca may have committed a breach of Section 3.1.

***Confidential Treatment Requested

18.10.2

In the event that any payments, which would be affected by a reduction hereunder, become due for payment after the discovery and notification of such breach such payments shall be made by Flexion when due, but in the event that AstraZeneca is found in the dispute resolution procedure set out in Section 24.3 to have breached the licence grant set out it in Section 3.1 of this Agreement, such payments shall be promptly repaid by AstraZeneca plus accrued interest in accordance with Section 7.13 above for the period from the payment date by Flexion until repayment by AstraZeneca.

18.10.3

If the breach occurs or is discovered by Flexion after […***…], then Flexion shall […***…].

19	Force Majeure

19.1

In this Agreement, “Force Majeure” means an event which is beyond a non-performing Party’s reasonable control, including an act of God, act or omission of the other Party, strike, lock-out or other industrial/labour dispute (whether involving the workforce of the Party so prevented or of any other Person), war, riot, civil commotion, terrorist act, malicious damage, epidemic, quarantine, fire, flood, storm, natural disaster or compliance with any law or governmental order, rule, regulation or direction, whether or not it is later held to be invalid.

19.2

The Force Majeure Party, shall within fifteen (15) days of the occurrence of a Force Majeure event, give notice in writing to the other Party specifying the nature and extent of the event of Force Majeure, its anticipated duration and any action being taken to avoid or minimize its effect. Subject to providing such notice and to Section 19.1, the Force Majeure Party shall not be liable for delay in performance or for non-performance of its obligations under this Agreement (other than obligations to pay monies due), in whole or in part, nor shall the other Party have the right to terminate this Agreement, except as otherwise provided in this Agreement, where non-performance or delay in performance has resulted from an event of Force Majeure. The suspension of performance allowed hereunder shall be of no greater scope and no longer duration than is reasonably required.

***Confidential Treatment Requested

19.3	The Force Majeure Party shall take all steps as are necessary to (a) bring the Force Majeure event to a close or (b) find a solution by which the Agreement may be performed despite the continuation of the event of Force Majeure.

19.4

If the Force Majeure Party is prevented from performing its obligations (other than obligations to pay monies due) due to a Force Majeure event for a continuous period in excess of six (6) months after the date of the occurrence of the Force Majeure event, and such failure to perform would constitute a breach of this Agreement in the absence of such Force Majeure event, the other Party may terminate this Agreement immediately by written notice to the Force Majeure Party, in which case neither Party shall have any liability to the other except for those rights and liabilities that accrued prior to the date of termination, provided that such right to terminate shall not be available if the Force Majeure event is caused by an act or omission of the other Party.

20	Assignment

Neither Party may assign its rights or, except as provided in Section 3.5 (Flexion’s right to sublicense) and Section 3.9 (Change of Control not resulting in termination of this Agreement), delegate its obligations under this Agreement, whether by operation of law or otherwise, in whole or in part without the prior written consent of the other Party, which consent shall not be unreasonably withheld or delayed, except that each Party shall always have the right, without such consent, (a) to perform any or all of its obligations and exercise any or all of its rights under this Agreement through any of its Affiliates, and (b) on written notice to the other Party, to assign any or all of its rights and delegate any or all of its obligations hereunder to any of its Affiliates. AstraZeneca shall always have the right on written notice to Flexion to assign any of all of its obligations hereunder to any successor in interest (whether by merger, acquisition, asset purchase or otherwise) to those assets to which this Agreement relates. Any permitted successor of a Party or any permitted assignee of all of a Party’s rights under this Agreement that has also assumed all of such Party’s obligations hereunder in writing shall, upon any such succession or assignment and assumption, be deemed to be a party to this Agreement as though named herein in substitution for the assigning Party, whereupon the assigning Party shall cease to be a

party to this Agreement and shall cease to have any rights or obligations under this Agreement. All validly assigned rights of a Party shall inure to the benefit of and be enforceable by, and all validly delegated obligations of such Party shall be binding on and be enforceable against, the permitted successors and assigns of such Party, provided that such Party, if it survives, shall remain jointly and severally liable for the performance of such delegated obligations under this Agreement. Any attempted assignment or delegation in violation of this Article 20 shall be void.

21	Sub-Contracting

Flexion shall have the right to sub-contract the performance of any of its obligations under this Agreement without the prior consent of AstraZeneca, provided that it shall remain liable for the performance or non-performance of any such obligations.

22	Severability

If any provision of this Agreement is held to be invalid, illegal or unenforceable, in any respect, then, to the fullest extent permitted by Applicable Law: (a) such provision will be given no effect by the Parties and shall not form part of this Agreement, (b) all other provisions of this Agreement shall remain in full force and effect, and (c) the Parties shall use their best efforts to negotiate a provision in replacement of the provision held invalid, illegal or unenforceable that is consistent with Applicable Law and achieves, as nearly as possible, the original intention of the Parties. To the fullest extent permitted by Applicable Law, the Parties waive any provision of law that would render any provision in this Agreement invalid, illegal or unenforceable in any respect.

23	Governing Law

This Agreement shall be governed by and construed in accordance with the laws of England, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

24	Dispute Resolution and Arbitration

24.1	If a dispute arises between the Parties relating to the existence, negotiation, validity, formation, interpretation, breach, performance or application of this Agreement, the Parties shall use the following procedure in good faith prior to either Party pursuing judicial remedies.

24.2

Each Party shall notify the other Party of the dispute in accordance with Article 25. The Parties shall use good faith efforts to resolve such dispute within thirty (30) days after delivery of such notice, which good faith efforts shall include at least one in-person meeting between representatives of each Party having decision-making authority (subject only to Board of Directors’ or equivalent approval, if required). All discussions under this Article 24 are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

24.3

Any dispute arising out of or relating to the existence, negotiation, validity, formation, interpretation, breach, performance or application of this Agreement shall be settled by binding arbitration in accordance with the ICC rules of arbitration. A sole arbitrator shall be appointed in accordance with such ICC rules of arbitration. The place of arbitration shall be London. The language used in the arbitration proceedings shall be English. The arbitration shall be governed by the Arbitration ▇▇▇ ▇▇▇▇ to the exclusion of any inconsistent state laws and judgment on the award rendered by the arbitration may be entered by any court having jurisdiction. Nothing in this Section 24.3 will preclude either Party from seeking equitable relief in accordance with Section 11.6 or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding. The statute of limitations of England and Wales applicable to the commencement of a lawsuit shall apply to the commencement of arbitration under this Section 24.3.

25	Notices

25.1	Notice Requirements.
