Moreover, other than as explicitly set forth in Section 3.1 Amgen shall not be responsible for any financial or other obligation (including without limitation any financial or other obligation relating to clinical development of Epratuzumab) incurred by Immunomedics prior to, on or after the Closing Date. 14.0 PAYMENTS 14.1 Beginning with [* ], Amgen shall deliver to Immunomedics, within [* ] after the close of each calendar quarter thereafter until the expiration of Amgen's obligation to pay Royalties for such Product under Section 11.5, a statement setting forth the Net Sales of such Product during the previous quarter, together with a payment of Royalties due for such quarter. Upon written notice by Immunomedics, interest shall accrue on any Royalties not paid when due (at the [* ] rate [* ], from the due date until the date of payment). 14.2 Amgen shall maintain the necessary books and records to determine the correctness of any payment of Royalties hereunder, and such books and records shall be open to inspection for three years following the end of the period to which they pertain. Once per calendar year Immunomedics shall have the option, upon thirty (30) days prior written notice to Amgen, to engage at its own expense an independent certified public accountant, reasonably acceptable to Amgen, to examine in confidence, upon reasonable notice and during Amgen's regular business hours, those books and records of Amgen as may be necessary to determine the correctness of any payment of Royalties hereunder for the previous three (3) year period. The report of such accountant shall be limited to a certificate verifying any statement provided or payment submitted by Amgen during such period but may include, in the event such accountant shall be unable to verify the correctness of any such payment, information relating to why such payment is unverifiable and Amgen shall receive a copy of each such report concurrently with receipt by Immunomedics. In the event that such payment is unverifiable, Amgen and Immunomedics shall use good faith efforts to arrive at an equitable solution. In the event an inspection reveals, as set forth in a final report, an underpayment of [* ] or more in any quarter, Amgen shall pay the costs of the inspection and shall promptly pay to Immunomedics any underpayment with interest from the date such amount(s) were due (at [* ] rate [* ] from the due date until the date of payment). In the event an inspection reveals, as set forth in a final report, an overpayment by Amgen hereunder, Amgen shall have the right to credit the excess amount against any of its then- future payments due under this Agreement. 14.3 Net Sales received in currencies other than United States Dollars shall be converted into the United States Dollar equivalent, at the average rate of exchange for the quarter (as calculated by averaging the rate of exchange at the close of business of the last day of each month of said quarter) as reported in International Financial Statistics (publisher, International Monetary Fund) during the Royalty period of such Net Sales, or in the event International Financial Statistics is not available then The Wall Street Journal, for the currency of the country in which the sale is made at the average rate of exchange during the Royalty period of such Net Sales. If -8- Amgen (or a Sublicensee of Amgen under this Agreement) is unable to convert a foreign currency into United States Dollars for reasons beyond its control, or is restricted by law, regulation or court order from remitting Royalties from any country of sale, Amgen shall cause such payment to be made to Immunomedics by deposit to the credit and account of Immunomedics or its designated nominee in any commercial bank designated by Immunomedics in the applicable country. Amgen shall deliver to Immunomedics proper evidence of such deposit. 14.4 Amgen shall be entitled to deduct from all Royalties payable hereunder by Amgen to Immunomedics, any taxes (excluding any income taxes) or other similar fees which are required by any foreign government to be withheld by Amgen on Royalties payable hereunder by Amgen to Immunomedics (provided that Amgen shall furnish Immunomedics with prior written notice of such deduction). 14.5 Immunomedics shall treat all financial information subject to review under Section 14.0, or under any related sublicense agreement, as Amgen's Confidential Information. Immunomedics shall be responsible for this financial information and shall cause its agents who have a need for access to such financial information to be bound to obligations of confidentiality, at least as restrictive as Immunomedics' obligations of confidentiality herein. 14.6 While Royalties for a Product shall be calculated and paid quarterly, any difference between the annual Royalty based on aggregating quarterly calculations of Net Sales and the annual Royalty based on actual Net Sales for the year, and any required Royalty adjustments, shall be made by an adjustment payment by Amgen at the time the 4/th/ quarter Royalty payment is made or by an adjustment credit against Amgen's future Royalty obligations. [* ] 15.0 DEVELOPMENT 15.1 Other than for Immunomedics' work under the [* ]Agreements as expressly permitted by Amgen hereinbelow, Amgen shall have the sole and full control, authority, discretion and right to conduct, fund and make all decisions regarding the development of Product(s) (including, but not limited to, preclinical pharmacology, toxicology, nomination of any Product for clinical development, final approval of clinical protocols and clinical development) and regulatory affairs related thereto (including, but not limited to, interaction with Governmental Authority(ies), the preparation and submission of Regulatory Filings and product registration) in the Territory [* ] as set forth in Section 15.5. Until such time as Immunomedics sublicenses Amgen under and/or terminates the [* ] Agreements pursuant to Section 2.3 (at which time Immunomedics shall have no further rights as set forth hereinabove), Immunomedics agrees not to further approve any protocols or take any other action under such [* ] Agreements, without the prior approval of Amgen. 15.2 Amgen shall own all right, title and interest in and to [* ], Regulatory Filings and Governmental Approvals. Notwithstanding anything to the contrary in this Agreement, Immunomedics shall have no rights with respect to the preparation, filing and ownership of any such Regulatory Filings and Governmental Approvals, but will, upon Amgen's reasonable request, assist Amgen in the preparation of such Regulatory Filings and in all material communications to or from Governmental Authority(ies) (at Amgen's expense). -9- 15.3 [* ] 15.4 [* ]. 15.5 Amgen (or its Sublicensees), on its own or with Third Party collaborators or consultants, shall have the right to conduct research and development activities with Product(s) in the Territory (but not outside the Territory, unless Immunomedics provides its prior written approval); provided -------- however, that notwithstanding the foregoing, Amgen shall have the right to - ------- complete all activities outside of the Territory relating to the [* ] conducted under [* ] and extensions thereof (and have a continuing right to consult with the investigators involved with such [* ]). Immunomedics (or its licensees outside of the Territory), on its own or with Third Party collaborators or consultants shall have the right to conduct research and development activities with Product(s) outside the Territory, but not in the Territory, unless Amgen provides its prior written approval (which may be withheld in Amgen's absolute sole discretion). 15.6 For so long as required by Governmental Authority(ies), Amgen and Immunomedics shall each promptly notify the other of any events in their respective territories reportable to Governmental Authority(ies) in the United States under 21 C.F.R. 314.80 (as such requirements may be amended from time-to- time) and any similar or equivalent reporting obligations to other Governmental Authority(ies) throughout the world. 15.7 In addition to participating in the meetings set forth in Section 7.3, on a [* ] basis, Amgen shall provide Immunomedics with a detailed written summary of the status of Amgen's clinical development activities relating to Epratuzumab. Immunomedics may discuss and comment on these [* ] reports and, at the request of Immunomedics, Amgen shall make available one or more members of its Epratuzumab clinical product development team to meet and discuss such written summary with Immunomedics, at times and at locations (for example, via personal visits or telephone discussion) as mutually agreed by the parties. 15.8 At any time during the term of this Agreement, Amgen shall [* ] for a 2/nd/ Generation Product. Upon [* ], such 2/nd/ Generation Product shall be included within the definition of "Product" (A.39 of Exhibit A) and be subject to the terms of this Agreement. 16.0 MANUFACTURING 16.1 Amgen shall have the sole right to manufacture Product(s) in the Territory and to make all decisions with respect thereto, except as expressly set forth in Section 16.2. 16.2 Until [* ], Immunomedics (or its subcontractors) shall supply Amgen with Amgen's requirements of clinical grade, filled and finished Epratuzumab for use in all [* ] Trials for the treatment of patients with [* ] non-Hodgkin's lymphoma ("NHL") deemed necessary by the FDA for approval of a U.S. BLA for Epratuzumab (specifically including, but not limited to, those [* ] Trials conducted under [* ] and extensions thereof). 16.2.1 In the event the worldwide clinical requirements for Epratuzumab exceed the manufacturing capacity of Immunomedics (and all of its subcontractors) prior to [* ]. -10- 16.2.2 Epratuzumab shall be manufactured by Immunomedics in accordance with mutually-agreed-upon specifications and in accordance with current Good Manufacturing Practices (as defined in the Code of Federal Regulations) in a manufacturing process and facility as described in the applicable IND(s) filed with the FDA. Amgen shall have the right to review and consult on the manufacturing of Epratuzumab, and Immunomedics shall address all reasonable comments provided by Amgen. Amgen shall also have the right to inspect and audit any parties involved in the manufacturing process and to have its representatives be present at the manufacturing facilities. Amgen shall have the right to ensure that raw material suppliers maintain compliance with current Good Manufacturing Practices, including having one or more Amgen employees in each supplier facility during any appropriate hours of operation to the extent necessary to ensure compliance with current Good Manufacturing Practices. Immunomedics shall be responsible for the finish and fill of Epratuzumab in unlabeled vials.

However, it is recognized and agreed by the parties that the goals described above depend on Amgen developing [* ] and that there can be no guarantee by Amgen to meet these goals. In the event Amgen is unable to meet either of its covenants under Section 16.3, Amgen shall pay a one-time fee of [* ] ($[* ]) to Immunomedics, [* ]. 16.5 After licensure of such Epratuzumab manufacturing facility by or on behalf of Amgen, Amgen shall assume sole responsibility for the manufacture of Epratuzumab for use in the Territory. Immunomedics shall retain the right to manufacture all or part of the requirements from its own manufacturing facility and/or to contract with a Third Party to produce sufficient quantities of Epratuzumab for development and commercialization outside the Territory. [* ] 16.6 Notwithstanding anything to the contrary in this Agreement, Amgen shall have no obligation, for any reason or under any circumstance, [* ]. 16.7 Amgen and Immunomedics shall negotiate in good faith the terms and conditions whereby Amgen would supply Epratuzumab to Immunomedics (and/or its licensees outside of the Territory) for their needs in the B Cell Malignancy Field outside of the Territory. In conducting such good faith discussion, the parties shall consider, among other things, all the risks and costs associated with a potential supply arrangement and a fair sharing of such risks and costs. The foregoing shall be neither a commitment on the part of Immunomedics to purchase, nor a commitment on the part of Amgen to supply, Epratuzumab unless and until the parties reach a mutually satisfactory definitive agreement. 17.0 COMMERCIALIZATION 17.1 Amgen shall have the sole right to commercialize (including, but not limited to, the promotion, marketing and sales of) Product(s) in the Territory and to make all decisions with respect thereto (including, but not limited to, determination of price, sales and distribution, packaging, labeling, language to be included on the package insert, promotion, detailing and selection of trademarks and Phase IV clinical trials), subject to its obligations under Section 19.5. 18.0 DILIGENCE -12- 18.1 Amgen shall [* ] to develop, manufacture, distribute, market and sell Product(s) in the Territory. 18.2 [* ]. 18.3 Development of Epratuzumab within the [* ] Field.

Additionally, if after all databases are locked on all [* ] Trials required for the [* ] NHL filing if such [* ] Trials are completed before such [* ] Trials for the[* ] NHL filing, Amgen shall, within [* ] thereafter, prepare the clinical results section of the United States BLA so as not to unduly delay the filing of such BLA following subsequent completion of the other sections (including the CMC section) of such BLA, provided however, that the FDA criteria for efficacy and safety are met, ---------------- and that there is no new negative information concerning commercialization or safety issues. In the event Amgen is unable to meet either of its covenants under this Section 18.3.2, Amgen shall pay to Immunomedics [* ] . 18.3.3 Other than as set forth in Section 18.3.1, if Amgen discontinues the development of Epratuzumab in [* ] NHL, all rights granted with respect to Epratuzumab shall revert to Immunomedics, and this shall have the effect of termination of this Agreement with respect to Epratuzumab, in accordance with the terms of Section 21.3.2. 18.4 Development of Epratuzumab [* ]. The parties recognize and agree that this development depends on a variety of factors including, but not limited to, the [* ]. -13- 18.5 Development of 2/nd/ Generation Product(s). 18.5.1 Amgen intends to [* ]clinical trials with Epratuzumab [* ] in the Territory. The parties recognize and agree that this development depends on a variety of factors including, but not limited to, the scientific rationale and evidence for therapeutic activity of Epratuzumab [* ], the benefits demonstrated in pre-clinical models of Epratuzumab [* ], and the commercial opportunity presented by Epratuzumab [* ] (including an assessment of the market and other competitive products, but excluding other Amgen products). [* ] 18.5.2 In the event Amgen discontinues the development of Epratuzumab for any reason, Amgen (a) shall provide notice thereof to Immunomedics, (b) shall use [* ] to develop a 2/nd/ Generation Product as a Product (for which Amgen shall have given notice under Section 15.8) and (c) shall initiate a clinical trial with any such Product by a date which is [* ], otherwise Amgen shall return all its remaining license rights to Product(s) under Sections 2.1, 2.2. and 2.3 and transfer all previously untransferred Amgen Data to Immunomedics.

The failure by the Indemnitee to deliver notice to the Indemnitor within a reasonable time after commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under Section 20.0, but the omission to deliver notice to the Indemnitor will not relieve the Indemnitor of any liability that it may have to the Indemnitee other than under Section 20.0.
