5.7		[ * ].

Sales by Sub-licensees

5.8		Onyx shall pay to BTG whichever is the greater of (i) [ * ]% of all Net Receipts received by Onyx or its Affiliates from any Sub-licensee or its Affiliates; or (ii) a royalty of [ * ]% of the Net Sales Value of all Licensed Products sold by Non-Affiliate Sub-licensees or their Affiliates or any subsequent sub-licensee thereof.

5.9		In the event that the royalty payment calculated by a Non-Affiliate Sub-licensee of Onyx or a Sub-licensee of any Affiliate of Onyx, or any subsequent sub-licensees thereof, as being due to Onyx under the relevant Sub-licence Agreement during any Year prove, following verification carried out by Onyx or an independent professional accountant appointed by

Onyx for the purpose of calculating that the monies paid to Onyx were correctly calculated and accurate, to be inaccurate (and, therefore, the monies paid to BTG in accordance with Clause 5.8 are inaccurate) Onyx shall either (as applicable):

	5.9.1		within [ * ] days of the end of the month in which such verification was carried out, pay to BTG the balance of the monies due; or

	5.9.2		within [ * ] days of receipt of written notification from Onyx that Onyx has paid more than was due, BTG shall reimburse Onyx for such sum. Such notification shall include sufficient evidence to enable BTG to verify the accuracy of such notification.

5.10

Onyx’s obligations to pay royalties in accordance with Clauses 5.5 and 5.6 shall terminate in accordance with the provisions of Clause 3.2. Onyx’s obligations to make payments under Clause 5.8 shall terminate at the end of the Term.

Infringement of Third Party Patents

5.11		If it is not reasonably possible to sell and/or have sold a Licensed Product, or to manufacture a Licensed Product for sale, in one or more countries without infringing one or more Valid Claims of third party patents that apply to or cover the inventions claimed in the Licensed Patents in such countries (“Third Party Claims”) and as a consequence Onyx is required to make and does make royalty payments or licence fees to a non-Affiliate independent third party in respect of such one or more Third Party Claims in order to sell a Licensed Product, or to manufacture a Licensed Product for sale, in such countries then, subject to the provisions of Clause 5.12, Onyx may deduct from the royalties that are otherwise due to BTG as provided in Clause 5.5 and 5.6 in respect of the Licensed Product that is sold or manufactured (as the case may be) in the countries covered by the Third Party Claims, [ * ]% of the royalty payments or license fees paid by Onyx to Third Parties in respect of that Licensed Product in the countries covered by the Third Party Claims (“Third Party Royalty”). For the avoidance of doubt, Onyx may only make deductions from royalties pursuant to this Clause 5.11 to the extent that the royalty payments or licence fees made to the third party concerned relate solely to Third Party Claims applying to or covering the inventions claimed in the Licensed Patents.

5.12		In the event that Onyx is unable to deduct from a particular royalty payment the full deduction in respect of Third Party Royalties that is permitted by Section 5.11, the unrealized portion such deduction will be carried over to subsequent royalty payments.

5.13		In no circumstances shall any provisions of this Agreement (including Clauses 5.11, 5.12 and the provision in Clause 1.33 setting out the manner in which Net Sales Value shall be calculated where a Licensed Product is sold as a Combination Product) operate to reduce the effective royalty on Net Sales Value payable by Onyx under Clause 5.5 to less than [ * ]% or under Clause 5.6 to less than [ * ]%.

5.14		The provisions of (a) Clauses 5.11 and 5.12 and the provisions of (c) Clause 1.33 which sets out the manner in which Net Sales Value shall be calculated where a Licensed Product is sold as a Combination Product, cannot both be applied to the same sale of a Licensed Product.

15.		MAINTENANCE OF THE PATENTS

15.1		Subject to Clause 15.2, BTG shall pay all renewal fees payable in respect of the granted Licensed Patents as and when such renewal fees become due (subject to BTG’s right to make use of grace periods where available and if necessary).

15.2		If BTG does not wish to continue to pay the renewal fees in respect of a granted Licensed Patent then BTG shall notify Onyx of its intention to allow the specified granted Licensed Patent to lapse at least [ * ] before the next renewal fee is due. Onyx shall have the right to pay the renewal fees in respect of such granted Licensed Patent.

16.3		BTG shall provide Onyx with such assistance as Onyx may reasonably request in connection with any proceedings against Infringers. Onyx shall pay BTG’s reasonable out-of-pocket expenses properly incurred in providing the requested assistance and, where suing in BTG’s name, indemnify and hold BTG harmless against BTG’s liabilities, costs, expenses and losses properly incurred in providing the requested assistance.

16.4		Onyx shall keep BTG fully informed of and consult with BTG with respect to the progress of and developments in any proceedings against Infringers including any settlement discussions with the defendants or potential defendants of such proceedings and shall provide to BTG copies of all claims, statements of case, counter-claims and defences prepared in relation to any proceeding against Infringers.

16.5		Onyx may negotiate settlements with Infringers but shall not conclude any settlement without having received BTG’s prior written approval of terms of the settlement, such approval not to be unreasonably withheld.

16.6		Any damages, proceeds, settlement sums or awards received by Onyx in relation to any Infringement (together referred to as “Damages”) shall be deemed to be Net Sales Value or Net Receipts, whichever would result in the greater payment to BTG. Accordingly, Onyx shall pay to BTG the payment set out in Clause 5.5 or 5.8 (which ever is the greater) on any Damages received after deduction from the Damages of Onyx’s legal fees incurred in taking action in respect of the Infringement and any of BTG’s costs or expenses that are paid by Onyx.

16.7		If for any reason Onyx fails to initiate or prosecute proceedings against any Infringer then BTG may at its absolute discretion and at its own cost and expense take proceedings (or continue any existing proceedings commenced by Onyx) against such Infringer. Onyx shall provide such assistance as BTG may from time to time reasonably request in connection with such proceedings including making available to BTG such records, information and evidence in Onyx’s possession or control which may be of assistance to BTG. Any damages, proceeds, settlement sums or awards received by BTG in relation to any Infringement shall be the sole property of BTG.

16.8		If an Infringer against whom Onyx has initiated infringement proceedings files counterclaims for revocation of any of the granted Licensed Patents, then Onyx shall

promptly notify BTG of such counterclaims and shall, notwithstanding Clause 17, have the right to defend, in collaboration with BTG, such counterclaims.

17.2		Except as set forth in Clause 16.8, BTG shall have the first right but not the obligation to defend the Revocation Proceedings.

17.3		If BTG does not wish to defend or continue to defend Revocation Proceedings then BTG shall promptly notify Onyx and Onyx may at Onyx’s own cost and expense defend or continue to defend the Revocation Proceedings referred to in BTG’s notice provided that, where such Revocation Proceedings are being defended or continued in BTG’s name, Onyx shall indemnify and hold harmless BTG against any and all liability, damage, costs and expenses (including awards of costs and damages) incurred by BTG arising out of Onyx’s continuation of such Revocation Proceedings.

17.4		Subject to the availability of suitably qualified staff, each party shall provide the other party with such assistance as the other party shall reasonably request in connection with any Revocation Proceedings. The party requesting such assistance shall pay the other party’s reasonable out-of-pocket expenses properly incurred in providing the requested assistance.

17.5		For the avoidance of doubt, in no circumstances shall BTG be required to refund any payments made under this Agreement and in accordance with its terms, including in the case where a Licensed Patent is wholly or partly revoked, cancelled or otherwise ceases to be in force.
