In connection with ImmunoGen’s consideration of the exercise of a Co-Development Option with respect to each Licensed Product, Biotest shall (a) as soon as practicable and in any event on or before [***] ([***]) days after the Early Stage Option Commencement Date and/or for the Late Stage Option Commencement Date, as the case may be, present in person to ImmunoGen, and/or provide ImmunoGen with, all information Controlled by Biotest reasonably necessary to assist ImmunoGen in determining whether to exercise its Co-Development Option; and (b) upon written request by ImmunoGen and approval by the JDC, provide ImmunoGen with any additional information Controlled by Biotest that ImmunoGen reasonably determines may be necessary or useful to ImmunoGen in exercising such Co-Development Option, including without limitation any additional information concerning the Development Plan applicable to that Licensed Product. Such information will be subject to confidentiality.
		

		
			5.1.3     Estimated Co-Development Costs.   If ImmunoGen exercises its Co-Development Option for a Co-Developed Product, (a) Biotest shall provide ImmunoGen with Biotest’s non-binding, good faith estimate of Co-Development Costs it expects to incur with respect to that Co-Developed Product for each Calendar Year for the next five (5) Calendar Years and (b) the Parties will jointly prepare a budget for that Co-Developed Product based on such estimate, which shall allocate expected costs between the Parties and, which shall be reviewed and updated by the Parties not less than once each Calendar Year.  The Parties hereby agree that, unless approved by the JDC, any costs or expenses incurred by a Party in excess of the estimated costs allocated in the Co-Development Plan to such Party as set forth in the Co-Development Plan shall be the sole responsibility of such Party.
		

		
			5.1.4     Allocation of Shared Clinical Trial Costs.    
		

		
			(a)       Use of Shared Clinical Trial Data. On and after the date of exercise by ImmunoGen of its Co-Development Option for a Co-Developed Product and continuing for the Term of this Agreement, each Party shall provide written notice to the other Party to the extent it intends to make Material Use of any Shared Clinical Trial Data.  If such use of Shared Clinical Trial Data enables a Party to [***] [***] [***] [***] [***] [***], such Party shall pay the applicable Shared Clinical Trial Cost Sharing Percentage of such Shared Clinical Trial Costs.  As promptly as practicable following such exercise, the Parties shall agree to a mechanism for providing all Shared Clinical Trial Data. 
		

		
			(b)       Payment Adjustments.

			Trial.  Such final accounting shall also include a reasonably detailed calculation of the net amount that one Party may owe the other Party for such costs in the case of Material Use, as applicable.  The net amount payable shall be due within thirty (30) days after receipt of an invoice pursuant to Section 5.1.4(d).  
		

		
			(c)       Audit.  For a period commencing upon the initiation of a Shared Clinical Trial and ending [***] ([***]) years after the completion of such Shared Clinical Trial, each Party shall keep complete and accurate records of associated Shared Clinical Trial Costs in sufficient detail to allow the accuracy of the payments hereunder to be confirmed. Each Party shall have the right for a period of [***] ([***]) years after the final accounting of such Shared Clinical Trial Costs for a particular Calendar Quarter to appoint at its expense an independent certified public accountant reasonably acceptable to the other Party to inspect or audit the relevant records of the other Party and its Affiliates to verify that the amount of such Shared Clinical Trial Costs was correctly determined.  The Audited Party and its Affiliates shall each make its records available for inspection or audit by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon reasonable notice from the Auditing Party, solely to verify that Shared Clinical Trial Costs hereunder were correctly determined.  Such inspection or audit right shall not be exercised by the Auditing Party more than once in any Calendar Year.  All records made available for inspection or audit shall be deemed to be Confidential Information of the Audited Party.  The results of each inspection or audit, if any, shall be binding on both Parties. In the event there was an error in the amount of Shared Clinical Trial Costs reported by the Audited Party hereunder, (a) if the amount of Shared Clinical Trial Costs was over-reported, the Audited Party shall promptly (but in any event no later than thirty (30) days after the Audited Party's receipt of the independent accountant's report so concluding) make payment to the Auditing Party of a percentage of the over-reported amount taking into account the equal sharing of Co-Development Costs and (b) if the amount of Shared Clinical Trial Costs was underreported, the Auditing Party shall promptly (but in any event no later than thirty (30) days after the Auditing Party's receipt of the independent accountant's report so concluding) make payment to the Audited Party of a percentage of the underreported amount taking into account the equal sharing of Co-Development Costs.  The Auditing Party shall bear the full cost of such audit unless such audit discloses an over reporting by the Audited Party of more than [***] ([***]) of the aggregate amount of Shared Clinical Trial Costs reportable in any Calendar Year, in which case the Audited Party shall reimburse the Auditing Party for all costs incurred by the Auditing Party in connection with such inspection or audit. 
		

		
			(d)       Data Audit.  Promptly following the submission of each Regulatory Filing, and any amendments or supplements thereto, the Party making such submission shall provide a full and complete copy of such filing to the other Party for purposes of determining whether the submitting Party has made Material Use of the other Party’s Shared Clinical Trial Data without having paid in full its applicable Shared Clinical Trial Cost Sharing Percentage associated with such Shared Clinical Trial Data.  In the event that a Party made Material Use of the other Party’s Shared Clinical Trial Data in such submission and therefore was able to [***] [***] [***] [***] [***] [***] [***] in the respective territory, the submitting Party shall pay the shortfall of its applicable Shared Clinical Trial Cost Sharing Percentage or the amount needed to match its applicable Shared Clinical Trial Cost Sharing Percentage, as the case may be, to the other Party upon written request and as invoiced by the other Party.

			(e)       Survival.  In the event that a Party enters into an agreement with a Third Party with respect to the conduct by such Third Party of Shared Clinical Trials, such Party shall use commercially reasonable efforts to include in such contracts provisions for cost sharing of Shared Clinical Trial Data consistent with those set forth in this Section 5.1.4. 
		

		
			5.1.5     Allocation of Pivotal MAY Compound Process Development Costs. 
		

		
			(a)       Payment by Biotest.  Notwithstanding anything to the contrary in this Agreement, provided that ImmunoGen has exercised a Co-Development Option, Biotest shall pay ImmunoGen a portion of the Pivotal MAY Compound Process Development Costs equal to the Pivotal MAY Compound Process Development Percentage. Any costs and expenses paid by Biotest to ImmunoGen after the Effective Date for process development activities for pivotal MAY Compounds shall be deducted from the amount payable by Biotest pursuant to this Section 5.1.5.  In connection therewith, ImmunoGen estimates as of the Effective Date that the aggregate Pivotal MAY Compound Process Development Costs shall not [***] [***] [***] [***] ([***]).
		

		
			(b)       Payment of Pivotal MAY Compound Process Development Costs.  
		

		
			(i)       Initial Payment. Within [***] ([***]) days of the exercise by ImmunoGen of a Co-Development Option pursuant to Section 5.1.1(a), ImmunoGen shall provide Biotest with a reasonably detailed written accounting of the Pivotal MAY Compound Process Development Costs incurred through the date of exercise of the Co-Development Option and the applicable Pivotal MAY Compound Process Development Percentage. Biotest shall pay the amount reflected in such accounting with [***] ([***]) days of receipt of such accounting.  
		

		
			(ii)       Subsequent Payments. Subject to Section 5.1.5(b)(i), within [***] ([***]) days of the end of each Calendar Quarter following the exercise by ImmunoGen of a Co-Development Option pursuant to Section 5.1.1(a), Biotest shall pay the applicable Pivotal MAY Compound Process Development Percentage of the Pivotal MAY Compound Process Development Costs incurred over such Calendar Quarter using a method of allocation to be determined by the JFC in good faith, based on the method of allocation described in Section 5.1.5(b)(i) above.  
		

		
			(c)       Records; Audit Rights. For a period of [***] ([***]) years following receipt by Biotest of any accounting described in this Section 5.1.5, ImmunoGen shall keep complete and accurate records pertaining to the Pivotal MAY Compound Process Development Costs and the Pivotal MAY Compound Process Development Percentage in sufficient detail to allow the accuracy of the payments hereunder to be confirmed. At each meeting of the JDC the Parties shall update the JDC as to such Pivotal MAY Compound Process Development Costs incurred through the date of such JDC meeting. ImmunoGen shall keep complete and accurate records of associated Pivotal MAY Compound Process Development Costs in sufficient detail to allow the accuracy of the payments hereunder to be confirmed. Biotest shall have the right to appoint at its expense an independent certified public accountant reasonably acceptable to ImmunoGen to inspect or audit the relevant records of ImmunoGen and its Affiliates to verify that the amount of such Pivotal MAY Compound Process Development Costs was correctly determined.

			or places where such records are customarily kept, upon reasonable notice from Biotest, solely to verify that Pivotal MAY Compound Process Development Costs hereunder were correctly determined.  Such inspection or audit right shall not be exercised by Biotest more than once in any Calendar Year.  All records made available for inspection or audit shall be deemed to be Confidential Information of ImmunoGen.  The results of each inspection or audit, if any, shall be binding on both Parties. In the event there was an error in the amount of Pivotal MAY Compound Process Development Costs reported by ImmunoGen hereunder, (a) if the amount of Pivotal MAY Compound Process Development Costs was over-reported, ImmunoGen shall promptly (but in any event no later than [***] ([***]) days after the ImmunoGen's receipt of the independent accountant's report so concluding) make payment to Biotest of the amount owed to Biotest, and (b) if the amount of Pivotal MAY Compound Process Development Costs was underreported, Biotest shall promptly (but in any event no later than [***] ([***]) days after Biotest's receipt of the independent accountant's report so concluding) make payment to ImmunoGen of the amount owed to ImmunoGen.  Biotest shall bear the full cost of such audit unless such audit discloses an over reporting by ImmunoGen of more than [***] [***] ([***]) of the aggregate amount of Pivotal MAY Compound Process Development Costs reportable in any Calendar Year, in which case ImmunoGen shall reimburse Biotest for all costs incurred by Biotest in connection with such inspection or audit.
		

		
			5.2       Reconciliation and Auditing of Co-Development Costs.    
		

		
			5.2.1    Reconciliation.  Within [***] ([***]) days following the end of each Calendar Quarter following the exercise of the Co-Development Option applicable to a given Co-Developed Product, each of ImmunoGen and Biotest shall submit to the JFC a written report setting forth in reasonable detail all Co-Development Costs incurred by each such Party over such Calendar Quarter.  Within [***] ([***]) days following the JFC’s receipt of such written reports, the JFC shall prepare and submit to each Party a written report setting forth in reasonable detail (a) the calculation of all Co-Development Costs incurred by both Parties over such Calendar Quarter and (b) the calculation of the net amount owed by ImmunoGen to Biotest or by Biotest to ImmunoGen in order to ensure the equal sharing of the Co-Development Costs.  The net amount payable shall be paid by ImmunoGen or Biotest to the other, as applicable, within [***] ([***]) days after the distribution by the JFC of such written report.  If the JFC determines that one Party has overrun the budget for a particular item, the amount by which the actual expense exceeded the budgeted amount shall be borne in its entirety by the Party incurring the overrun.
		

		
			5.2.2    Records; Audit Rights. Each Party shall keep and maintain for [***] ([***]) years complete and accurate records of Co-Development Costs incurred with respect to Licensed Products in sufficient detail to allow confirmation of same by the JFC.  Each Party shall have the right for a period of [***] ([***]) years after such Development Cost is reconciled in accordance with Section 5.2.1 to appoint at its expense an independent certified public accountant reasonably acceptable to the other Party to inspect or audit the relevant records of the other Party and its Affiliates to verify that the amount of such Co-Development Costs was correctly determined.  The Audited Party and its Affiliates shall each make its records available for inspection or audit by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon reasonable notice from the Auditing Party, solely to verify that Co-Development Costs hereunder were correctly determined.

			Calendar Year.  All records made available for inspection or audit shall be deemed to be Confidential Information of the Audited Party.  The results of each inspection or audit, if any, shall be binding on both Parties. In the event there was an error in the amount of Co-Development Costs reported by the Audited Party hereunder, (a) if the amount of Co-Development Costs was over-reported, the Audited Party shall promptly (but in any event no later than [***] ([***]) days after the Audited Party's receipt of the independent accountant's report so concluding) make payment to the Auditing Party of a percentage of the over-reported amount consistent with the equal sharing of Development Costs and (b) if the amount of Co-Development Costs was underreported, the Auditing Party shall promptly (but in any event no later than [***] ([***]) days after the Auditing Party's receipt of the independent accountant's report so concluding) make payment to the Audited Party of a percentage of the underreported amount consistent with the equal sharing of Development Costs.  The Auditing Party shall bear the full cost of such audit unless such audit discloses an over reporting by the Audited Party of more than [***] [***] ([***]) of the aggregate amount of Co-Development Costs reportable in any Calendar Year, in which case the Audited Party shall reimburse the Auditing Party for all costs incurred by the Auditing Party in connection with such inspection or audit.   
		

		
			5.3       Compliance.   Biotest and/or ImmunoGen, as applicable, shall each perform their respective obligations under each Co-Development Plan and Co-Development Manufacturing Plan in good scientific and business manner and in compliance in all material respects with all Applicable Laws; provided, that, for purposes of clarity, with respect to each activity performed under the Co-Development Plan, that will or would reasonably be expected to be submitted to a Regulatory Authority in support of a Regulatory Filing or Drug Approval Application, Biotest and/or ImmunoGen, as applicable, shall each comply in all material respects, in the Co-Development Territory, with the regulations and guidance of the relevant authorities in the Co-Development Territory.  
		

		
			5.4       Commercialization Diligence.  Biotest and/or ImmunoGen, as applicable, shall each use Commercially Reasonable Efforts during the Term to Develop and to Commercialize Co-Developed Products in the Co-Development Territory. If a Party at any time reasonably believes that the other Party is not meeting its diligence obligations pursuant to this Section 5.4, such Party may give, in the form of detailed reasons, written notice to the other Party requesting written justification, in the form of detailed reasons, that would support the proposition that such other Party is meeting such diligence obligations.  In such event, such other Party shall provide such written justification within [***] ([***]) days after such notice is given.  In the event that the other Party does not reasonably justify that it is meeting its diligence obligations pursuant to this Section 5.4 within such [***] ([***]) day period, then the Party giving notice shall have the right, in its sole discretion, to exercise such rights or remedies that it may have under this Agreement, at law or in equity.

			5.5       Co-Promotion Rights.    
		

		
			5.5.1     Option to Jointly Sublicense.    
		

		
			(a)       Early Stage Co-Development Option.
		

		
			 (i)       Initial Sublicense Decision Date. If ImmunoGen exercises an Early Stage Co-Development Option with respect to a Co-Developed Product, then within [***] ([***]) days following the First Interim Analysis of the first [***] [***] [***] [***] with respect to such Co-Developed Product, the Parties shall discuss in good faith and decide whether to jointly sublicense the right to Develop and Commercialize such Co-Developed Product in the Co-Development Territory to a single Third Party, in which case the Parties shall [***] in the consideration received from such Third Party with respect to the grant of such sublicense for the Co-Development Territory.
		

		
			(ii)      Second Sublicense Decision Date.  In the event that ImmunoGen exercises the Early Stage Co-Development Option with respect to a Co-Developed Product and the Parties (A) have, pursuant to Section 5.5.1 (a) (i), decided to sublicense the right to Develop and Commercialize such Co-Developed Product to a single Third Party, but the Parties have not entered into an agreement with a Third Party to Develop and Commercialize such Co-Developed Product in accordance with Section 5.5.1(a)(i) and (B) have not obtained accelerated approval from the FDA in accordance with Subpart E of 21 C.F.R. 312 with respect to such Co-Developed Product, then within [***] ([***]) days following the First Interim Analysis of the first [***] [***] [***] [***] with respect to such Co-Developed Product, the Parties shall discuss in good faith and decide whether to jointly sublicense the right to Develop and Commercialize such Co-Developed Product in the Co-Development Territory to a single Third Party, in which case the Parties shall [***] in the consideration received from such Third Party with respect to the grant of such sublicense for the Co-Development Territory.
		

		
			(b)       Late Stage Co-Development Option.  In the event that ImmunoGen exercises a Late Stage Co-Development Option with respect to a Co-Developed Product, but the Parties have not obtained accelerated approval from the FDA in accordance with Subpart E of 21 C.F.R. 312 with respect to such Co-Developed Product, then within [***] ([***]) days following the First Interim Analysis of the [***] [***] [***] [***] [***] with respect to such Co-Developed Product, the Parties shall discuss in good faith and decide whether to jointly sublicense the right to Develop and Commercialize such Co-Developed Product in the Co-Development Territory to a single Third Party, in which case the Parties shall [***] in the consideration received from such Third Party with respect to the grant of such sublicense for the Co-Development Territory. 
		

		
			5.5.2    Failure to Reach Agreement.  If the Parties are unable to affirmatively decide to jointly sublicense the right to Develop and Commercialize a Co-Developed Product to a single Third Party pursuant to Section 5.5.1(a) or (b), the Parties shall (a) prepare and execute a mutually acceptable Co-Promotion Agreement between the Parties (the “Co-Promotion Agreement”) in good faith and with sufficient diligence as is required to execute and deliver the Co-Promotion Agreement within [***] [***] [***] ([***]) days from the expiration of the applicable [***]-day period and (b) jointly Co-Promote the Co-Developed Product.  The Co-Promotion Agreement shall contain such provisions as are usual and customary for inclusion in a co-promotion agreement between companies in the pharmaceutical industry of comparable sizes to the respective Parties and shall contain suitable provisions regulating activities equivalent to Section 4.6 that relate to Co-Developed Products in the Co-Development Territory. In the event the Parties fail to execute and deliver the Co-Promotion Agreement within the [***] [***] [***] ([***]) day period described in this Section 5.5.2, the Parties shall (A) use reasonable efforts to complete such negotiations and to execute and deliver the Co-Promotion Agreement as soon as

			possible after such [***] [***] [***] ([***]) day period and (B) without limiting the generality of the foregoing, after the expiration of such [***] [***] [***] ([***]) day period, each produce a list of issues on which they have failed to reach agreement and submit its list to the JSC to be resolved in accordance with Section 2.1.6.  
		

		
			5.5.3    Development Cost-Sharing.  For the avoidance of doubt, if the Parties decide to jointly sublicense to a single Third Party the right to Develop and Commercialize a Co-Developed Product as described in Section 5.5.1(a) or (b), the Parties’ respective obligations to share in the Co-Development Costs applicable to that Co-Developed Product in accordance with Sections 5.1 and 5.2 shall continue until the effective date of the sublicense agreement.
		

		
			5.5.4     Option to Unilaterally Sublicense after Commercialization.  If at any time during the period commencing on the [***] [***] of the [***] [***] [***] [***] [***] [***] [***] and continuing for a period of [***] ([***]) days, either Party determines that it wishes to engage any Third Party to assume its Co-Promotion rights and fulfill its Co-Promotion obligations with respect to a Co-Developed Product, then notwithstanding anything to the contrary in Section 5.5.2 and subject to Section 8.3.1 and 8.3.2, either Party shall have the right to engage any Third Party to fulfill its Co-Promotion obligations with respect to a Co-Developed Product in accordance with this Section 5.5.4, and such Party shall provide written notice of same to the other Party (the “ROFN Notice”, whereby ROFN means Right Of First Negotiation).  The Party receiving the ROFN Notice shall have [***] ([***]) days from the date of the ROFN Notice to provide a written response (the “ROFN Response”) as to whether or not it wishes to enter into negotiations with the other Party with respect to such Co-Promotion activities. If the ROFN Response is not received within the [***] ([***]) day response period, the Party providing the ROFN Notice shall thereafter have the right to engage any Third Party to fulfill its Co-Promotion obligations with respect to a Co-Developed Product.  If the ROFN Response is received within the [***] ([***]) day response period and states that the other Party wishes to enter into negotiations with the Party providing the ROFN Notice, the Parties shall negotiate in good faith for a period of up to [***] [***] [***] ([***]) days from the date of the ROFN Response with respect to the terms and conditions of such rights; provided, that the Parties acknowledge and agree that such negotiations shall not be exclusive and the Party providing the ROFN Notice shall also have the right during such period to conduct discussions with one or more Third Parties regarding the grant of such rights.  If after the Parties are unable to agree upon terms and conditions of such rights on or before the expiration of such [***] [***] [***] ([***]) day period, then the Party providing the ROFN Notice shall thereafter have the right to engage any Third Party to fulfill its Co-Promotion obligations with respect to a Co-Developed Product.  For purposes of clarity, the rights of the Parties with respect to a Co-Developed Product under this Section 5.5 shall not affect Biotest’s rights to grant sublicenses to any Licensed Product in accordance with Section 8.3. If either Party grants a sublicense according to this Section 5.5.4, such Party shall be deemed to have guaranteed that such Sublicensee will fulfill all of such Party’s obligations under this Agreement and the Co-Promotion Agreement applicable to the subject matter of such sublicense; and the respective Party shall not be relieved of any of its obligations pursuant to this Agreement and the Co-Promotion Agreement as a result of such sublicense.
		

		
			5.6       Co-Development Marketing and Sales Plan.  The JMC shall prepare a Co-Development Marketing and Sales Plan for each Co-Developed Product for the Co-Development Territory in accordance with Section 5.1.1(b), which shall include, but not be limited to, (a)

			demographics and market dynamics, market strategies, and estimated launch date of such Co-Developed Product in the Co-Development Territory, (b) a sales and expense forecast (including at least five (5) years of estimated sales and expenses) and manufacturing plans for such Co-Developed Product in the Co-Development Territory, (c) a marketing plan (including five (5) year Advertising and Detailing forecasts and pricing strategies) for such Co-Developed Product in the Co-Development Territory, and (d) a five (5) year budget for such Co-Developed Product for the Co-Development Territory.  The Co-Development Marketing and Sales Plan and annual written updates thereto shall be submitted to the JMC for review by a date to be established by the JMC taking into account Biotest's and ImmunoGen's annual budget planning calendars, but no later than December 31 of each Calendar Year.
		

		
			5.7       Change in Co-Promotion Percentage. As will be provided in the Co-Development Marketing and Sales Plan, it is the expectation of the Parties that both Parties will typically contribute fifty percent (50%) to the yearly marketing and sales expenses for a Co-Developed Product and therefore share all profits in an equal split.  If either Party wishes to increase its Co-Promotion activities with respect to a Co-Developed Product (“Additional Co-Promotion Activities”) by increasing the marketing and sales investments above the amount the other party is ready to spend, unequal contributions to the yearly budget shall be possible,   unless otherwise provided in the Co-Promotion Agreement, according to the following provisions. The Party wishing to increase its Co-Promotion activities shall submit a written proposal to the JMC which shall describe in reasonable detail the Additional Co-Promotion Activities and the justification for Additional Co-Promotion Activities, an estimated budget and timeline with respect thereto, and the expected adjustment to be made to the Co-Development Marketing and Sales Plan and to the Parties’ respective Co-Promotion Percentages to reflect the relative value of Additional Co-Promotion Activities to be conducted by the submitting Party (as so adjusted, the “Adjusted Co-Promotion Percentage”).  The JMC shall have to approve this proposal, and each Party shall ensure that its representatives in the JMC do not unreasonably withhold such approval. Upon approval of the proposal and the Adjusted Co-Promotion Percentage by the JMC, (a) the Co-Development Marketing and Sales Plan shall be amended accordingly; (b) the submitting Party shall thereafter conduct the Additional Co-Promotion Activities included in the approved proposal; (c) the Adjusted Co-Promotion Percentage shall thereafter be the Co-Promotion Percentage of the Parties; and (d) the Parties will thereafter continue to share Co-Promotion Costs with respect to that Co-Developed Product, and receive a percentage of the Net Income derived from that Co-Developed Product, according to the Adjusted Co-Promotion Percentage. The Change in Co-Promotion Percentage shall be valid for one Calendar Year and shall be extended or terminated by the JMC in the course of the generation of the new Co-Development Marketing and Sales Plan.
		

		
			5.8       Labeling.  All product labels for Co-Developed Products shall include, to the extent allowed by Applicable Laws, in equal prominence, the names of both Biotest and ImmunoGen or their respective Sublicensees.  The JMC shall have the responsibility of meeting not less frequently than annually and deciding whether changes in the particular appearance in labeling of packaging and containers of Co-Developed Products or in the product information is required.  In addition to the annual review, an emergency review can be implemented at any time by the JMC.

			6.       CONSIDERATION AND FUNDING
		

		
			6.1       Upfront Fee.  Biotest shall pay ImmunoGen an upfront fee in the amount of One Million Dollars (US $1,000,000) in immediately available funds within [***] ([***]) days from the Effective Date, which shall be non-creditable and non-refundable, it being understood that in the event that ImmunoGen has not applied for, or been given relief from, any obligation it may have to pay taxes in Germany with respect to the upfront fee by the date the upfront fee is due and Biotest reasonably determines that a tax is applicable to such upfront fee, Biotest may, upon notice to ImmunoGen, deduct the amount of any German tax applicable thereto and transfer it to the applicable German tax authorities.  ImmunoGen may apply for a refund with the German tax authorities and Biotest shall provide reasonable assistance to ImmunoGen in connection therewith.
		

		
			6.2       R&D Funding.   During the period commencing on the Effective Date and continuing on a Licensed Product by Licensed Product basis until the earlier of (a) the exercise by ImmunoGen of a Co-Development Option with respect to such Licensed Product and (b) the expiration of the Research Program term, Biotest shall pay ImmunoGen the aggregate FTE Cost for all FTEs used by ImmunoGen in the conduct of ImmunoGen Activities on a quarterly basis, based on the FTE Rate and the Research Plan and/or Development Plan.  Within [***]  ([***]) days following the last day of each Calendar Quarter during the conduct of the Research Program, ImmunoGen shall issue an invoice reflecting the FTE Costs for such Calendar Quarter, as reflected in the then-current Research Plan and Biotest shall pay each such invoice within [***] ([***]) days from receipt.

			For purposes of clarity, no milestone payments shall be payable under this Section 6.3.1 for any milestone events whether occurring within or outside of the Co-Development Territory for a Co-Developed Product on and after the date of exercise by ImmunoGen of a Co-Development Option with respect to such Co-Developed Product. Biotest shall pay each milestone only once per specific Biotest Product, regardless of how many indications, formulations or methods of treatments will be related to such Biotest Product. A specific Biotest Product shall be defined by the combination of Anti-CD138 Antibody + MAY Compound + Linker. Exchanging either of the three parts shall create a new specific Biotest Product. Combination Products shall not trigger a milestone payment provided that the Biotest Product contained therein has already caused a milestone payment.

			include a description of the applicable milestone event.  In the event that, notwithstanding the fact that Biotest has not given such a notice, ImmunoGen believes any such milestone event has occurred, it shall so notify Biotest in writing and shall provide to Biotest data, documentation or other information that supports its belief.  Any dispute under this Section 6.3.2 that relates to whether or not a milestone event has been achieved shall be referred to the JSC to be resolved in accordance with Section 2.1.6.

			6.4       Payment of Royalties; Royalty Rates; Payment of Net Income; Accounting and Records.
		

		
			6.4.1    Payment of Royalties.  Biotest shall pay ImmunoGen a royalty based on Annual Net Sales of each Royalty-Bearing Product commencing with the Calendar Year (or partial Calendar Year) in which the First Commercial Sale of such Royalty-Bearing Product occurs and ending upon expiration of the Royalty Term for such Royalty-Bearing Product, at the following rates:
		

		
			(a)       Biotest Products
		

			
					
						Annual Net Sales of Biotest Products Worldwide

			actually makes royalty payments to any Third Party (“Third Party Payments”) in order to obtain a license to an issued patent or patents in the absence of which the Licensed Technology or Licensed Patent Rights portion of a Licensed Product could not legally be developed, manufactured, used, sold or imported in such country (as evidenced, to the extent reasonably requested by ImmunoGen, by an opinion of patent counsel), then the royalties payable to ImmunoGen for such Licensed Product under this Agreement with respect to such country may be reduced by [***] percent ([***]%) of the amount of such Third Party Payments.  Notwithstanding the foregoing, such reductions shall in no event reduce the royalty rate for such Licensed Product applicable under Section 6.4.1 with respect to such country to less than (i) [***] percent ([***]%), with respect to the royalty rate set forth in Section 6.4.1(a) above; (ii) [***] percent ([***]%), with respect to the royalty rates set forth in Section 6.4.1(b)(i); and (iii) [***] percent ([***]%), with respect to the royalties set forth in Section 6.4.1(b)(ii) above.
		

		
			(d)       Combination Products.  In determining Net Sales of any Combination Products under this Agreement in any country, Net Sales shall first be calculated in accordance with the definition of “Net Sales” then multiplied by the percentage value of the Royalty-Bearing Product contained in the Combination Product, such percentage value being the quotient obtained by dividing the current market price of the Royalty-Bearing Product by the sum of the separate current market price of the Royalty-Bearing Product in such country and the other ingredients which are therapeutically or biologically active contained in the Combination Product in such country.  The current market price of each therapeutically or biologically active ingredient and of the Royalty-Bearing Product shall be for a comparable quantity sold in such country to that contained in the Combination Product and of the same class, purity and potency.   When no current market price is available for any therapeutically active ingredient or for the Royalty-Bearing Product in such country, the Parties shall agree in good faith upon a hypothetical market price with respect to the Combination Product, allocating the same proportions of costs, overhead and profit as are then allocated to all similar substances then being made and marketed by Biotest and having an ascertainable market price in such country; provided, however, that if the Parties are unable to agree upon such hypothetical market price, the Parties shall submit the matter promptly to the Parties respective Designated Senior Officers for resolution.
		

		
			(e)       Payment Dates and Reports.  Royalty payments shall be made by Biotest within [***]  ([***]) days after the end of each Calendar Quarter commencing with the Calendar Quarter in which the First Commercial Sale of each Royalty-Bearing Product occurs.  All payments shall be made by wire transfer to the credit of such bank account as shall be designated in writing from time to time by ImmunoGen minimum [***] ([***]) days before the relevant payment is due.  Biotest shall also provide, at the same time each such payment is made, a report showing: (i) the Net Sales of each Royalty-Bearing Product by country in the Royalty-Bearing Territory; (ii) the basis for any deductions from gross amounts billed or invoiced to determine Net Sales; (iii) the applicable royalty rates for such Royalty-Bearing Product; (iv) the exchange rates used in calculating any of the foregoing; (v) any reductions in royalties to be paid through payment of Third Party Payments; and (vi) a calculation of the amount of royalty due to ImmunoGen.
		

		
			6.4.2     Net Income Payments.  In lieu of paying any royalty payments with respect to each Co-Developed Product in the Co-Development Territory, each Party shall receive its Co-Promotion Percentage of all Annual Net Income derived from sales of that Co-Developed Product

			in the Co-Development Territory as described herein for as long as there are sales of such Co-Developed Product in the Co-Development Territory (such payments, the “Net Income Payments”).  Within [***] ([***]) days following the end of each Calendar Quarter commencing on and after the date of First Commercial Sale of each Co-Developed Product,  Biotest and ImmunoGen shall submit to the JFC all Commercialization Expenses incurred by it with respect to such Co-Developed Product in the Co-Development Territory, as well as the Cost of Goods of the applicable Co-Developed Product, as well as Net Sales.  Within [***] ([***]) days following the end of the Calendar Quarter, the JFC shall submit to the Parties a written report setting forth in reasonable detail (a) the calculation of Annual Net Income, determined in accordance with Schedule 1 attached hereto and (b) the calculation of the amount of Annual Net Income payable to each Party in accordance with its respective Co-Promotion Percentage for that Co-Developed Product. In the event that the amount of Net Income Payments is not equally distributed between the Parties, the Party having received the greater portion of Net Income Payments shall pay to the other Party that portion of the excess amount within [***] ([***]) days following the end of the Calendar Quarter which generates the correct distribution according to the applicable Co-Promotion Percentage.
		

		
			6.4.3     Records; Audit Rights.  Biotest and its Affiliates and Sublicensees shall keep and maintain for [***] ([***]) years from the date of each payment of royalties hereunder complete and accurate records of their respective Commercialization Expenses, as well as all gross sales and Net Sales by Biotest and its Affiliates and Sublicensees of each Licensed Product, in sufficient detail to allow royalties to be determined accurately and ImmunoGen and its Affiliates and Sublicensees shall keep and maintain for [***] ([***]) years from the date of each payment of Net Income Payments complete and accurate records of its Commercialization Expenses, as well as all gross sales and Net Sales of each Co-Developed Product in sufficient detail to allow Net Income Payments to be determined accurately.  Each Party shall have the right for a period of [***] ([***]) years after receiving any such payment to appoint at its expense an independent certified public accountant reasonably acceptable to the other Party to inspect or audit the relevant records of such Party, its Affiliates and Sublicensees to verify that the amount of such payment was correctly determined.  The Audited Party, its Affiliates and Sublicensees shall each make its records available for inspection or audit by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon reasonable notice from the Auditing Party, solely to verify that Commercialization Expenses, royalty and Net Income payments hereunder were correctly accounted for or determined.  Such inspection or audit right shall not be exercised by the Auditing Party more than once in any Calendar Year or more than once with respect to sales of a particular Licensed Product in a particular period.  All records made available for inspection or audit shall be deemed to be Confidential Information of the Audited Party.  The results of each inspection or audit, if any, shall be binding on both Parties.  In the event there was an underpayment by the Audited Party hereunder, the Audited Party shall promptly (but in any event no later than [***] ([***]) days after the Audited Party’s receipt of the independent accountant’s report so concluding) make payment to the Auditing Party of any shortfall.  In the event that there was an overpayment by the Audited Party hereunder, the Auditing Party shall promptly (but in any event no later than [***] ([***]) days after the Auditing Party’s receipt of the independent accountant’s report so concluding) refund to the Audited Party the excess amount.  The Auditing Party shall bear the full cost of such audit unless such audit discloses an underreporting by the Audited Party of more than [***] percent ([***]%) of the aggregate amount of royalties or Net Income Payments payable, or

			Commercialization Expenses allocable, in any Calendar Year, in which case the Audited Party shall reimburse the Auditing Party for all costs incurred by the Auditing Party in connection with such inspection or audit.
		

		
			6.4.4    Overdue Royalties, Net Income Payments and Milestones.  All royalty and Net Income Payments not made within the time period set forth in Section 6.4.1 and 6.4.2, and all milestone payments not made within the time period specified in Section 6.3.1, shall bear interest at a rate of [***] percent ([***]%) per month from the due date until paid in full or, if less, the maximum interest rate permitted by Applicable Laws.  Any such overdue royalty, Net Income Payment or milestone payment shall, when made, be accompanied by, and credited first to, all interest so accrued.
		

		
			6.4.5    Withholding Taxes.  All payments made by a Party hereunder shall be free and clear of any taxes, duties, levies, fees or charges except for applicable withholding taxes, if any.  The paying Party shall make any applicable withholding payments due from the non-paying Party on its behalf and shall promptly thereafter provide the non-paying Party with written documentation of any such payment sufficient to enable non-paying Party to satisfy the requirements of the United States Internal Revenue Service or any tax authority of any other country, as applicable, with regard to an application for a foreign tax credit for such payment.
		

		
			6.4.6    Foreign Currency Exchange.  All royalties and Net Income Payments shall be payable in full in United States Dollars, regardless of the countries in which sales are made.  For the purpose of computing Net Sales for Licensed Products sold in any currency other than United States Dollars, the quarterly royalty payment will be calculated as follows:
		

		
			(A/B) x C= United States Dollars royalty payment on Net Sales sold in any currency other than United States Dollars during a Calendar Quarter, where
		

		
			A= foreign “Net Sales” (as defined above) in such Calendar Quarter expressed in such foreign currency;
		

		
			B= foreign exchange conversion rate, expressed in local currency of the foreign country per United States Dollar calculated using a simple four point average, i.e., (the rate at the beginning of the quarter + the rate at the end of month one + the rate at the end of month two + the rate at the end of the quarter)/4 as provided by the ECB for such accounting period; and
		

		
			C= the royalty rate(s) applicable to such Net Sales under this Agreement.

Subject to Section 10.2.1(f), all costs, including, without limitation, attorneys’ fees, relating to such legal proceedings or other action shall be borne by [***]. If [***] does not take commercially reasonable steps to eliminate the Infringement within [***] [***] [***] ([***]) days from an Infringement Notice or within [***] ([***]) days in the case of a certification against a patent listed in the Orange Book, [***] shall have the right to defend the applicable CD138 Conjugate Patent Rights and/or Joint Patent Rights, at its sole cost and expense.
		

		
			(c)       ImmunoGen shall have the first right and option, but not the obligation, to eliminate any such Infringement that is covered by the Licensed Patent Rights and/or any Joint Patent Rights that contain one or more claims that cover MAY Compounds in general and/or that cover both a Licensed Product and one or more other products Controlled by ImmunoGen by taking reasonable steps, which may include the institution of legal proceedings or other action; provided, that, notwithstanding the foregoing, Biotest agrees to cooperate in good faith with ImmunoGen or any Third Party from which ImmunoGen has licensed ImmunoGen Patent Rights to determine the most reasonable method of eliminating the Infringement in view of the Parties’ respective interests and ImmunoGen’s obligations to such Third Party.  ImmunoGen agrees that, consistent with the Parties’ interests hereunder, Biotest shall be consulted with respect to decisions related to such defense of the Licensed Patent Rights and/or any Joint Patent Rights. Subject to Section 10.2.1(f), all costs, including, without limitation, attorneys’ fees, relating to such legal proceedings or other action shall be borne by ImmunoGen.  If ImmunoGen does not take commercially reasonable steps to eliminate the Infringement within [***] [***] [***] ([***]) days from any Infringement Notice (or [***] ([***]) days in the case of an Infringement under the Hatch-Waxman Act, e.g., in the case of a certification against a patent listed in the Orange Book), then Biotest shall have the right and option to do so at its expense.    
		

		
			(d)       Biotest shall have the first right and option, but not the obligation, to eliminate any such Infringement that is covered by the Biotest Patent Rights by taking reasonable steps, which may include the institution of legal proceedings or other action.

			(e)       ImmunoGen shall have the first right and option, but not the obligation, to eliminate any such Infringement that is covered by the Licensed Patent Rights  (to the extent such defense is not covered by Section 10.2.1[d]) and/or the ImmunoGen Patent Rights by taking reasonable steps, which may include the institution of legal proceedings or other action.  Subject to Section 10.2.1(f), all costs, including, without limitation, attorneys’ fees, relating to such legal proceedings or other action shall be borne by ImmunoGen. 
		

		
			(f)       Notwithstanding anything to the contrary in this Section 10.2.1, if ImmunoGen has exercised its Co-Development Option with respect to a Licensed Product under Section 5.1.1 of this Agreement, both Biotest and ImmunoGen (in each case directly or through a Third Party partner, as applicable) will be responsible for jointly eliminating any Infringement of CD138 Conjugate Patent Rights and/or Joint Patent Rights in the Co-Development Territory by reasonable steps, which may include the institution of legal proceedings or other action, at shared cost.  Notwithstanding this joint responsibility, the Parties agree that [***] shall lead the

			defense of such potential infringement, with full cooperation and input from [***].  All costs and expenses reasonably incurred by either Party under this subsection (f) shall, to the extent related to the Commercialization of a Co-Developed Product in the Co-Development Territory, be deemed to be Commercialization Expenses.
		

		
			(g)       Each Party shall have the right to participate, and be represented by counsel that it selects, in any legal proceedings or other action instituted under this Section by the other Party.  If a Party with the right to initiate legal proceedings under this Section to eliminate an Infringement lacks standing to do so and the other Party has standing to initiate such legal proceedings, then the Party with standing shall initiate such legal proceedings at the request and expense of the other Party. Neither Party shall settle any Infringement claim or proceeding under this Section 10.2.1 without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed.
		

		
			(h)       In any action, suit or proceeding instituted under this Section 10.2.1, the Parties shall cooperate with and assist each other in all reasonable respects.  Upon the reasonable request of the Party instituting such action, suit or proceeding, the other Party shall join therein and shall be represented using counsel of its own choice, at the requesting Party’s expense.  
		

		
			(i)       Any amounts recovered by the Parties pursuant to this Section, whether by settlement or judgment, shall be allocated in the following order: (i) first, to reimburse Biotest and ImmunoGen for their reasonable Out-of-Pocket Costs in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses); and (ii) then, (A) to the extent the Infringement relates to a Royalty-Bearing Product in the Royalty-Bearing Territory, to Biotest in reimbursement for lost sales associated with such Royalty-Bearing Products and to ImmunoGen in reimbursement for lost royalties owing hereunder based on such lost sales and (B) to the extent the Infringement relates to a Co-Developed Product in the Co-Development Territory, to the calculation of Net Income with respect to such Co-Developed Product.  Any other damages, awards or amounts recovered (including for punitive damages) shall be allocated as follows: (A) if [***] is the Party bringing such suit or proceeding or taking such other legal action, [***] percent ([***]%) to [***] and [***] percent ([***]%) to [***], (B) if [***] is the Party bringing such suit or proceeding or taking such other legal action, [***] percent ([***]%) to [***] and (C) if the suit is brought jointly, [***] percent ([***]%) to [***] Party.
		

		
			(j)       For purposes of clarity, the Parties acknowledge that this Section concerns enforcement of the various Patent Rights defined in this Agreement, and does not relate to ownership of the various Patent Rights defined in this Agreement, which are recognized to be separate legal issues.
		

		
			10.2.2  Defense of Claims.  In the event that any action, suit or proceeding is brought against either Party or any Affiliate or sublicensee of either Party alleging the infringement of the Technology or Patent Rights of a Third Party by reason of the conduct of the Research Program, the Development or Commercialization of any Licensed Product under the Licensed Patent Rights: (a) ImmunoGen as the owner of the Licensed Patent Rights shall have the right, but not the obligation, to defend such action, suit or proceeding at its sole expense; (b) Biotest shall have the right to participate by separate counsel at its own expense in any such action, suit or

			proceeding; and (c) the Parties shall cooperate with each other in all reasonable respects in any such action, suit or proceeding.  In the event that any action, suit or proceeding is brought against either Party or any Affiliate or sublicensee of either Party alleging the infringement of the Technology or Patent Rights of a Third Party by reason of the conduct of the Research Program, the Development or Commercialization of any Licensed Product under Biotest Patent Rights: (a) Biotest as the owner of the Biotest Patent Rights shall have the right, but not the obligation, to defend such action, suit or proceeding at its sole expense; (b) the Parties shall cooperate with each other in all reasonable respects in any such action, suit or proceeding.  If such action, suit or proceeding relates to Co-Developed Products in the Co-Development Territory or relates to Joint Patent Rights or CD138 Conjugate Patent Rights, both Parties shall equally share the cost and expense of any such action, suit or proceeding and the cost and expense of the above shall be used to calculate Net Income for that Co-Developed Product.  Each Party shall provide the other Party with prompt written notice of the commencement of any such suit, action or proceeding, or of any allegation of infringement of which such Party becomes aware, and shall promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such Party.  For purposes of clarity, nothing in this Section 10.2.2 shall affect the right of ImmunoGen to defend itself in any such action, suit or proceeding relating to ImmunoGen Patent Rights.  Biotest shall not compromise, litigate, settle or otherwise dispose of any such suit, action or proceeding that involves the use of ImmunoGen Patent Rights without ImmunoGen’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed.
		

		
			10.3      Trademark Prosecution.  Biotest shall be responsible for the filing, prosecution, defense and maintenance before all trademark offices of the Licensed Product Trademarks at Biotest’s expense.  In the event that ImmunoGen has exercised a Co-Development Option to a Licensed Product both Parties shall be responsible for the filing, prosecution, defense and maintenance before all trademark offices in the Co-Development Territory of the Licensed Product Trademarks of such Co-Developed Product under the direction of the JDC or JMC, as appropriate, and shall equally share all expenses related thereto.
		

		
			10.4      Orange Book Listing.  The Parties agree that, upon the filing of an NDA covering a Licensed Product, the Parties will designate which Party shall be responsible for listing the Patent Rights covering the Licensed Product in the Orange Book and, subject to the foregoing, the Party so designated shall promptly list such Patent Rights in the Orange Book.
		

		
			11.      TERM AND TERMINATION
		

		
			11.1      Term.  This Agreement shall commence on the Effective Date and shall continue in full force and effect until such time as all Royalty Terms for all Licensed Products have ended, unless earlier terminated in accordance with the provisions of this Section 11 (the “Term”). Thereafter, if not earlier terminated pursuant to Section 11.2, Biotest shall have a worldwide, fully paid-up and royalty-free license for the use and the Commercialization of all Licensed Products. In the event that either Party discontinues with its activities under this Agreement for good and valid reasons, including, without limitation, toxicological, pharmaceutical and ethical reasons, then the Parties shall, in good faith, discuss the situation and use commercially reasonable efforts in order to agree on an appropriate solution, including, without limitation, an early termination of or an amendment to this Agreement. In the event of a dispute between the Parties as to whether or not any discontinuation by a Party of its activities under this Agreement is justified by good

			and valid reasons, such dispute shall first, according to Section 2.1.6, be referred to the JSC, and, to the extent not resolved by the JSC, referred to arbitration according to Section 14.1.
		

		
			11.2      Termination.  This Agreement may only be terminated at any time by either Party, or by the Party specified, as follows:
		

		
			11.2.1   Termination for Breach.
