For the purpose of this LOI, Immunomedics and BSP are both referred hereinafter also a “Party” or the “Parties”, as applicable.

The Parties are currently in the process of negotiating in good faith toward a Master Service Agreement (the “Agreement”) for the commercial supply of the product, named IMMU-132 (the “Product”). This LOI confirms the mutual intentions of the Parties with respect to the negotiations of the Agreement and the commitments of the Parties for the manufacturing of the bulk drug substance and the commercial supply of the Product for the calendar year 2018, based on BSP’s proposal dated January 30, 2018 (the “Proposal”) and attached hereto as Exhibit A.

In consideration of the mutual covenants set forth in this LOI, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows.

1. Agreement. The Parties will use reasonably diligent efforts in good faith to negotiate, execute, and deliver the Agreement on or before July 30, 2018, unless extended by mutual agreement. The Parties agree to conduct the negotiations on a confidential basis.

2. Binding Forecast. The quantities of Product identified in Table 1 in Exhibit B represent the Parties’ current binding commitment (the “Binding Forecast”) for the manufacture and purchase of [***] Batches of bulk drug substance (“DS”) and [***] Batches of drug product (“DP”) distributed during each calendar quarter of 2018 at the prices agreed in the Proposal. The volumes of [***] Batches of DS and [***] Batch of DP specifically set forth in Table 2 of Exhibit 2 correspond to the minimum quantities for 2018 (the “Minimum Quantities”). Upon execution of this LOI, Immunomedics shall issue separate purchase orders (each a “Purchase Order”) for the Minimum Quantities of Product and for the Material Costs (as defined below in Section 5). The Purchase Order shall specify each manufacturing dates within such calendar quarter respectively for DS or DP, as set forth in Table 1. As used herein, “Batch” with respect to DS shall mean theoretical [***] Liters (10mg/mL per vial) and “Batch” with respect to DP shall mean theoretical [***] vials.

3. Financial Obligations. Throughout the term of this LOI [***], as distributed according to the manufacturing dates identified by the Parties, then Immunomedics is obligated to pay [***] per cent ([***]%) of the capacity reserved for the Binding Forecast at the price set forth in the Proposal, as amended from time to time, in accordance with the terms set forth in this Section 3. For clarity, the price for capacity reservation for any Batch of DS is €[***] and for any Batch

of DP is €[***]. In accordance with the provisions of this LOI, the Parties hereby agree that should Immunomedics not utilize the capacity reserved by BSP for the manufacture of the Minimum Quantities, then Immunomedics shall pay to BSP an amount equal to the product of (i) the difference between (A) the aggregate quantity of Product set forth in the Binding Forecast limited to the Minimum Quantities of Product for such calendar year, less (B) the aggregate quantity of Product ordered by Immunomedics for delivery in such calendar year (such difference, the “Order Shortfall”), multiplied by (ii) the prices applicable to the Order Shortfall for such calendar year (i.e. €[***] for any Batch of DS and €[***] for any Batch of DP). In addition, Immunomedics shall pay to BSP an amount equal to [***] Euro, as a reservation fee (the “Reservation Fee”) to compensate the remainder of the Binding Forecast for 2018, exclusive of the Minimum Quantities, provided that in the event Immunomedics orders an amount of DS or DP in excess of the Minimum Quantities in calendar year 2018, Immunomedics shall be credited the manufacture price for each Batch of DS and DP (as provided in Exhibit C) from the Reservation Fee, provided that Immunomedics shall issue purchase order for additional quantities at least [***] in advance of the specified delivery date for respective DS or DP Batches, such manufacture to be performed within [***], and provided that the intermediates (i.e. payload and mAb) necessary for manufacture of such additional quantities shall be delivered and released by Immunomedics before [***]. Upon receipt of the first Purchase Orders for the Material Costs and the Minimum Annual Quantities, BSP shall issue a separate invoice for the Material Costs, and BSP shall issue separate invoices for the Reservation Fee as provided in Exhibit C. The Minimum Quantities of Product shall be invoiced by BSP to Immunomedics in accordance with Section 5 below. The Reservation Fee shall be paid by Immunomedics in accordance with the payment schedule set forth in Exhibit C and [***] of the receipt of the relevant invoice by BSP and, in any event, within the calendar year 2018.

4. Intermediates. Should the intermediates (i.e. toxin and mAb) not be available to be released at BSP at least four (4) weeks before the manufacturing date then Immunomedics shall immediately notify BSP thereof. Promptly thereafter, the Parties shall meet to discuss in good faith if BSP can comply with the original schedule using its best efforts to do so, and if BSP cannot comply with the original schedule, BSP shall use best efforts to adjust the manufacturing in accordance with the terms of this LOI and with BSP’s production plan. Should the adjustment of manufacturing not be possible, the relevant production shall be cancelled and Immunomedics shall remain obligated to pay such part of unused capacity; provided that BSP is unable to fill the unused capacity with work from a third party after using best efforts to do so.

5. Payment. BSP will submit invoices upon completion of the Services at the issuance of the Certificate of Analysis by BSP. The material costs for an amount estimated (in good faith) to be equal to Euro [***] (€ [***]) (the “Material Costs”) shall be paid separately [***] by Immunomedics immediately upon receipt of the invoice by BSP.
