promptly destroy all remaining stocks of product in OPi’s possession, custody or control and provide evidence of such destruction to HPA promptly thereafter (subject to the retention by OPi of samples of Product required for regulatory purposes).

EUSA Pharma SAS, formerly called OPi SA, whose primary place of business and registered address is Les Jardins D’Eole, allee des sequoias F 69760, Limonest, France (EUSA), which expressions shall include its successors in title.

HPA and EUSA have entered into a Royalty Bearing Licence Agreement and Supply Agreement re Erwinia-Derived Asparaginase dated 22 July 2005 (RBLA) as amended by the First Amendment dated 22 December 2009.

HPA and EUSA now wish to further amend the RBLA and the Parties agree to be bound by the terms and conditions of the RBLA, as amended herein.

This Second Amendment confirms the mutual understanding between HPA and EUSA to amend certain terms and conditions of the RBLA.

DEFINITIONS AND INTERPRETATION

“Parties” means HPA and EUSA collectively;

Unless stated otherwise in this Second Amendment, terms with initial capitals in this Second Amendment shall have the same meaning attributed to them in Clause 1.1 of the RBLA;

References to the singular shall include the plural and vice versa.

Reference to Clauses and Schedules are to clauses and schedules of either the RBLA or this Second Amendment, as stated in the text of this Second Amendment. The headings to the Clauses in this Second Amendment are for convenience only and have no legal effect.

AMENDMENTS

With effect from 21 November 2011 the definition of Minimum Calculation Year, is deleted in its entirety and replaced with the following:

With effect from 21 November 2011 clause 3.2 of the RBLA is deleted in its entirety and replaced with the following:

HPA shall supply Product to EUSA

ex works Porton Down (Incoterms 2000)

on such other terms and conditions as are set out in Schedule 2, as amended from time to time.

With effect from 21 November 2011 clause 3.6 of the RBLA is deleted in its entirety and replaced with the following:

With effect from 21 November 2011 clause 4.1 of the RBLA is deleted in its entirety and replaced with the following:

PAYMENTS TO BE MADE BY EUSA

In consideration of the assistance and services hereby agreed to be rendered and of the licence hereby granted, EUSA shall both during the term of this Agreement in respect of all the Product sold by EUSA and after the termination of this Agreement in respect of any stocks of the Product held by EUSA at the date of termination and sold on or after such date by EUSA pay to HPA in addition to any other sums payable hereunder compensation equal to:

[ * ] per cent of the Net Sales when the Net Sales are up to and including [ * ] in any Minimum Calculation Year;

[ * ] per cent of Net Sales when the Net Sales are over [ * ] and up to and including [ * ] in any Minimum Calculation Year;

[ * ] per cent of the Net Sales when the Net Sales are over [ * ] and up to and including [ * ] in any Minimum Calculation Year;

[ * ] per cent of the Net Sales over [ * ] in any Minimum Calculation Year;

For clarity once an applicable threshold is reached the relevant compensation rate shall be applied to all cumulative Net Sales in the relevant Minimum Calculation Year backdated to the beginning of the then current Minimum Calculation Year.

The compensation will be payable in two parts:

a price per Vial of [ * ] (the “Transfer Price”), which is payable for the supply of Product, as invoiced in accordance with clause 11 or as otherwise agreed; and

a sum equivalent to a royalty on Net Sales, calculated as set out in clause 4.2.1.

The Transfer Price will be amended at the [ * ] using the following formula:

To the extent that EUSA is required by applicable law to deduct any amounts from such royalty payable by way of withholding or other tax, it shall make such deduction, pay the appropriate amount of tax deducted to the appropriate taxation authorities and provide HPA with an appropriate certificate of tax deduction.”

With effect from 21 November 2011, clause 4.2 of the RBLA is deleted in its entirety and replaced with the following:

From April 1st 2012 within [ * ] after the end of the relevant calendar month, EUSA shall furnish to HPA a written statement (the “Monthly Statement”) in the form set out in Appendix 1 attached to the Second Amendment setting out the monthly aggregate Net Sales for the relevant calendar month and the calendar year to date Net Sales of Product (the “Year to Date Total”), and the monthly

aggregate Transfer Price paid for Vials of Product sold during that calendar month and the aggregate Transfer Price paid for Vials sold in the calendar year to date.

EUSA will apply to the Year to Date Total the applicable compensation rate set out in clause 4.1.1, and calculate the relevant compensation payable on the Year to Date Total (“Year to Date Total Royalty’).

From the Year to Date Total Royalty, EUSA will subtract:

the calendar year to date aggregate Transfer Price for Vials of Product paid by EUSA to HPA for Product sold in the calendar year to date; and

the aggregate of the Year to Date Total Royalty paid by EUSA to HPA in the preceding months of the then current Minimum Calculation Year; and

[ * ] where such Vials are supplied by EUSA to an unconnected third party free of charge during the calendar year to date.

If the subtraction in clause 4.2.3 results in a positive sum, EUSAwill include details of all amounts payable by EUSA in the Monthly Statement for that Minimum Calculation Year in the calendar year to date. Following receipt of the Monthly Statement, HPA shall provide to EUSA an invoice in respect of such payments. Within [ * ] of the date of receipt of such invoice, EUSA will make payment (less any withholding or other tax EUSA is required to deduct) in favour of HPA for the amount due to HPA in respect of the preceding calendar month.

If the subtraction in clause 4.2.3 results in a negative sum, reflecting that payments made by EUSA to HPA in the calendar year to date exceeded the sums that ought otherwise to have been paid, EUSA may set off such over payments made in that calendar year to date against payments due to be made to HPA in the subsequent calendar months until the over payment has been fully balanced provided that [ * ]. The [ * ] can be varied in accordance with Appendix 1 of the First Amendment Agreement, although [ * ] will [ * ] instead of [ * ].”

PAYMENT OF PREVIOUS ROYALTIES DUE

Within [ * ] of the date of this Second Amendment, EUSA shall provide HPA with a statement of Net Sales made prior to 21 November 2011 to which the previous royalty rate [ * ] applies. HPA shall produce to EUSA an invoice in respect of such royalties due. Within [ * ] of the date of receipt of the invoice EUSA shall make payment (less any withholding or other tax EUSA is required to deduct) in favour of HPA for the amount of royalties due to HPA for the period prior to 21 November 2011.

EUSA shall within [ * ] of this Second Amendment provide to HPA an accurate statement setting out the number of Vials (excluding Product batches 151 and 152) that it held as at 21 November 2011.

Following the date of this Second Amendment, HPA shall, as soon as reasonably practicable, issue an invoice to EUSA [ * ] in respect of Product batches 151 and 152 which sum shall be paid in accordance clause 11 of the RBLA.

Within [ * ] of this Second Amendment EUSA will carry out a calculation in accordance with clauses 4.2.1 to 4,2.5 of the RBLA (as amended herein) in respect of Net Sales of Products made in the period from 21 November 2011 to 31 December 2011 and shall notify HPA in writing of the amount due and any sums payable to HPA shall be paid in accordance with clause 11 of the RBLA following receipt of HPA’s invoice for the same provided that [ * ] shall be [ * ] and [ * ].

Within [ * ] EUSA will carry out a calculation in accordance with clauses 4.2.1 to 4.2.5 of the RBLA (as amended herein) in respect of Net Sales of Products made in the period from [ * ] and shall notify HPA in writing of the amount due and any sums payable to HPA shall be paid in accordance with clause 11 of the RBLA following receipt of HPA’s invoice for the same provided that [ * ] shall be [ * ] and [ * ]. Thereafter, EUSA shall furnish HPA with a written Monthly Statement in accordance with clause 4.2.1.
