6. Capacity Schedule and Second Supplier

6.1. The Capacity Schedule. In the *** the Parties shall within the scope of the JSC establish a capacity schedule based on the Parties’ good faith estimate of the total requirements for C1 esterase inhibitor for the next calendar years, ***, which requirements shall comprise ***. These total requirements shall be balanced against Sanquin’s aggregate manufacturing capacity for C1 esterase inhibitor (including the capacity of any Affiliate and/or subcontractor capable of acting as a Second Supplier (as defined in Section 6.5), if any) (the “Capacity Schedule”). The Capacity Schedule shall be updated within the scope of the JSC no less frequently than annually, and shall include projects identified by the Parties to enhance manufacturing capacity. Furthermore as soon as practicable in *** the Parties shall negotiate in good faith, taking into account all applicable factors, to establish the Capacity Schedule for the next *** calendar years after ***, and so on. The Capacity Schedule may comprise, from time to time, projects that are in process as well as projects that will be implemented by the Parties, such as the projects set out in Sections 6.2 and 6.3 below.

6.2. In-Process Projects.

6.2.1. Existing Industrial Scale Project. Sanquin is in the process of implementing structural and equipment changes to the Amsterdam Manufacturing facility and to the Brussels Manufacturing Facility, as further described in the Capacity Schedule (the “Existing Industrial Scale Project”).

6.2.2. Under the Existing Industrial Scale Project, VBI has funded a total investment of *** euros, through a loan facility upon the terms set forth in Section 6.4 (the “Loan 1”), such loan covering ***% of the capital investment required for the Brussels Manufacturing Facility, and ***% of the capital investment required for the Amsterdam Manufacturing Facility. Sanquin shall provide the remaining ***% of the funding required to complete the Existing Industrial Scale Project as it relates to the Amsterdam Manufacturing Facility and shall use Commercially Reasonable Efforts to obtain Regulatory Approval to be able to manufacture the Product in such facility no later than ***.

6.2.3. In addition, Sanquin agrees to fund any necessary non clinical studies required as a result of the scale up resulting from the Existing Industrial Scale Project (“Scale Up”), including but not limited to conformance lot production (it being understood that the Source Plasma required for such conformance lot production

19/47

Execution copy dated 8 January 2010

will be supplied to Sanquin by VBI, free of charge) and testing, comparability testing between product from the licensed facility/process and the scaled up facility/process, and any other non-clinical studies required by the Regulatory Authorities to obtain approval of the Scale Up.

6.2.4. Small-Scale Doubling. Sanquin has completed the implementation of labor management changes that allow for an initial scale-up of the manufacturing capacity without prior approval of a variation to the BLA (the “Small-Scale Doubling”), such Small-Scale Doubling to become operational ***.

6.3. Additional Projects.

6.3.1. Sanquin shall cause to be implemented structural and equipment changes to the Brussels Manufacturing Facility in accordance with the Capacity Schedule for the purpose of accommodating an automated bottle cutting facility and related equipment (the “Bottle Cutting Facility Addition-Brussels”), financed through a loan facility to be provided by VBI or any of its Affiliates in the amount of 5 million euros upon the terms set forth in Section 6.4 (the “Loan 2”). It is anticipated that the Bottle Cutting Facility Addition-Brussels will be completed in accordance with the timeframe set forth in the Capacity Schedule.

Execution copy dated 8 January 2010

(iv) Sanquin shall continue to conduct its operations in a manner substantially similar to its current operations for all periods prior to the repayment in full of the Loan.

6.4.2. Given the Parties’ current understanding of the volumes of Product anticipated to be ordered by VBI in accordance with the provisions of Section 4.4, the discount per Unit of Product as under Section 6.4.1 allows Sanquin to pay back the Loan before January 1, *** (“Maturity Date”). Should VBI not order such anticipated volumes of Product then VBI shall waive the part of the Loan still outstanding as of the Maturity Date. Furthermore should this Agreement be terminated by Sanquin before the Maturity Date because of the uncured material breach of VBI, then VBI shall waive the part of the Loan still outstanding as of the date of termination. Also in the event of the filing of a petition for bankruptcy of VBI or any application for any equivalent insolvency proceedings in respect of VBI before the Loan has been fully paid back by Sanquin, the then outstanding balance of the Loan shall be forgiven.

6.4.3. Should, on the other hand, the Agreement be terminated by VBI because of the uncured material breach of Sanquin before the Loan has been fully paid back, then Sanquin shall pay to VBI the remaining principal amount of the Loan outstanding as of the date of termination within *** days from such termination date. For purposes of clarity, the Parties expressly agree that an event as described in Section ***, shall not be considered a default by Sanquin. Should such event take place before the Loan has been fully paid back by Sanquin and result in ***, then VBI shall ***.

6.5. Second Supplier.

6.5.1. Sanquin shall use commercially reasonable efforts to enter into one or more manufacturing agreement(s) (“Subcontracting Agreement”), as the case may be, with one or more Affiliates, including possibly CAF-DCF, and/or Third Party subcontractors reasonably acceptable to VBI (“Second Supplier”), pursuant to which Subcontracting Agreement the Second Supplier shall be in a position to manufacture certain quantities of Intermediates and/or Product to be agreed upon by the Parties and to be included in the Capacity Schedule, and to provide for a back-up manufacturing facility in order to reasonably secure the manufacturing of Product under this Agreement (including in the event that any Manufacturing Facility is temporarily out of operation). Timing of the entry into of the Subcontracting Agreement, the terms of the Subcontracting Agreement and the identity of the Second Supplier shall be discussed and agreed between the Parties within the scope of the JSC.

9.4. Notice of Claims. If any Party to be indemnified under this Section 9 (the “Indemnified Party”) has suffered or incurred any Loss, the Indemnified Party shall so notify the party from whom indemnification is sought (the “Indemnifying Party”) promptly in writing describing such Loss, the amount or estimated amount thereof, if known or reasonably capable of estimation, and the method of computation of such Loss, all with reasonable particularity and containing a reference to the provisions of this Agreement or any other agreement, instrument or certificate delivered pursuant hereto in respect of which such Loss shall have occurred.

No Indemnified Party may compromise or settle any Third Party Claim for which it is seeking indemnification hereunder without the consent of the Indemnifying Party. The Indemnifying Party shall permit the Indemnified Party to participate in, but not control, the defense of any such action or suit through counsel chosen by the Indemnified Party, provided that the fees and expenses of such counsel shall be borne by the Indemnified Party. If the Indemnifying Party elects not to control or conduct the defense of a Third Party Claim, the Indemnifying Party nevertheless shall have the right to participate in the defense of any Third Party Claim and, at its own expense, to employ counsel of its own choosing for such purpose.

9.5.2.

The Party prevented from performing hereunder shall use its commercially reasonably efforts to remove such disability as promptly as possible and shall continue performance whenever, and to the extent, such causes are removed. The Party so affected shall provide to the other Party a good faith estimate of the continuing effect of the Force Majeure Event and the duration of the affected Party’s non-performance, and periodic updates on a reasonable basis.
