Such minutes shall be circulated to the other Party’s Alliance Manager no later than [**] days following the meeting for review, comment and approval of the other Party. If no comments are received within [**] days of the receipt of the minutes by a Party, unless otherwise agreed, they shall be deemed to be approved by such Party. Furthermore, if the Parties are unable to reach agreement on the minutes within [**] days of the applicable meeting, the sections of the minutes that have been mutually agreed between the Parties by that date shall be deemed approved and, in addition, each Party shall record in the same document its own version of those sections of the minutes on which the Parties were not able to agree.

4.2.6 Each Party’s representatives to the JSC shall collectively have one (1) vote, except as otherwise provided in Section 4.2.4.

4.3 Advisory Board. Upon Genmab’s 50% Election, the JSC shall set up an advisory board consisting of [**] independent advisors with expertise within the fields of [**] (the “Advisory Board”). The Parties shall [**] share the costs associated with the Advisory Board. In case of a Withdrawal by one (1) of the Parties the Continuing Party shall be free to decide whether it wishes to maintain the Advisory Board at its own cost.

In case of Withdrawal by ADCT, Genmab shall have the casting vote in the JSC provided that Genmab elects to take over the Development of the ADC.

4.5 Changes to the Clinical Work Plan in Case of Joint Ownership. The Joint Steering Committee will be responsible for the oversight and approval of all changes and updates to the Clinical Work Plan. The Parties will ensure that the JSC is operating under the principles that both (i) speed (while at all times adhering to and complying with quality and regulatory requirements) and (ii) the limitation of costs related to the Development of the ADC are of the essence and also that the Parties have agreed to maintain the Clinical Plan Framework as the basis of the Parties understanding and commercial arrangement. In consequence, as soon as possible after Genmab’s 50% Election, the Parties will agree on certain criteria that the JSC will apply to decide in good faith on any proposed changes to the Clinical Work Plan, including timing and budget. The JSC shall be responsible for making any changes and updates to the Clinical Work Plan. In the event of a disagreement between members of the Joint Steering Committee regarding the Clinical Work Plan, each Party may request that the CEOs of the Parties meet to seek to come to a resolution. If the CEOs have not reached an agreement within [**] days after having been referred such disagreement, and the disagreement relates to medical, safety or CMC matters, then the JSC shall submit the disagreement to the Advisory Board. Any recommendation of the Advisory Board that results in the Clinical Work Plan staying within the Clinical Plan Framework shall be binding on the Parties, provided that the recommendation would not materially increase the CMC budgeted cost as such budget has been made pursuant to Section 5.1.1. If the recommendation of the Advisory Board will result in the Clinical Work Plan being changed beyond the Clinical Plan Framework or if there are serious safety concerns associated with the disagreement in question, the recommendation of the Advisory Board shall not be binding on the Parties. In such non-binding events, the CEOs shall meet again within [**] days of receipt of the recommendation of the Advisory Board and come to a resolution taking into strong consideration the input from the Advisory Board. If a resolution cannot be reached by the CEOs, then no changes or updates shall be made to the then current Clinical Work Plan.

Genmab shall inform the JSC of its comments, objections and suggested changes to such documents, budgets and presentation. The Joint Steering Committee shall evaluate the Proposed IND Submission and proposed Clinical Work Plan, and any comments provided by Genmab and attempt, with the understanding that time and cost is of the essence (while at all times adhering to and complying with quality and regulatory requirements), to include in the initial versions of the Proposed IND Submission and the Clinical Work Plan and budgets any input provided by either Party that keep the Clinical Work Plan within the Clinical Plan Framework. The JSC shall take into good faith consideration the comments from Genmab, but ADCT will have the casting vote on consideration of such comments and modifications, and may approve such Proposed IND Submission and proposed Clinical Work Plan and budgets, provided such are within the parameters set forth in the Clinical Plan Framework. The Parties anticipate that the protocol for the Phase I/II Clinical Trial contemplated in the Clinical Plan Framework shall consist of two (2) parts; the first part [**] targeted at dose escalation and the second part focused on safety and efficacy of the ADC. If the members of the JSC fail to reach an agreement on the selection of indication(s) for the first part of the Phase I/II Clinical Trial, [**]; provided that no such selection may result in the boundary parameters of the Clinical Plan Framework being exceeded. In the event that a Party does not agree with the indication(s) chosen for the second part of the Phase I/II, either Party may present its arguments to the Advisory Board, and the decision of the Advisory Board shall be [**] on the Parties. The process described in this Section 5.1.1 shall not begin any later than [**] months before the [**] deadline identified in Section 3.3, shall not occur more than once, shall take no longer than [**] days from start to finish, and shall result in final versions of the Proposed IND Submission and the Clinical Work Plan being produced no later than [**] months before the [**] deadline identified in Section 3.3.

(a) Upon the JSC’s approval of the final versions of the Proposed IND Submission and the Clinical Work Plan, Genmab shall within [**] days (“IND Review Period”) of such approval inform ADCT in writing whether Genmab:

(i) Elects to maintain its fifty percent (50%) ownership of the ADC by providing written notice to ADCT and making a catch-up payment to ADC of [**] of costs paid and to be paid by ADCT under the Pre-Clinical Work Plan (the “50% Election”) less Genmab’s Out-of-Pocket Expenses to hedge currency risk pursuant to Section 6.7.2. Any such 50% Election shall be subject to the reimbursement obligation contained in Section 3.4. In the event that the 50% Election is made by Genmab, Genmab further agrees to pay fifty percent (50%) of all future Development Costs; or

(ii) Elects not to make the payment specified in Section 5.1.2(a)(i), in which case Genmab’s interest shall be reduced to twenty-five percent (25%) (the “25% Election”). In the event that the 25% Election is made by Genmab, ADCT shall be the sole developing Party, have the casting vote on the JSC, and assume all costs for the future Development of the ADC.

(b) The failure of Genmab to make a timely election under this Section 5.1.2, shall result in the provisions of Section [**].

CLINICAL DEVELOPMENT IN CASE OF 50% ELECTION

6.1 Accounting and Financial Reporting. The Parties will each appoint one (1) representative with expertise in the areas of accounting, cost allocation, budgeting and financial reporting no later than [**] calendar days after Genmab’s 50% Election (“Finance Manager”). The Parties’ Finance Managers shall work together and report to the JSC in order to address the financial, budgetary and accounting issues which arise in connection with the work that each Party is to perform under the Clinical Work Plan.

Certain confidential information contained in this document, marked by [**], has been omitted because

6.3 The Parties’ Obligations under the Clinical Work Plan. Each Party shall use Commercially Reasonable Efforts to perform its obligations with respect to the Development of the ADC in accordance with the Clinical Work Plan and budget and all such activities shall be conducted in accordance with all applicable laws, including as applicable, GCPs, GLPs and GMPs. As part of such efforts, each Party shall commit the personnel and facilities necessary to carry out its obligations under the Clinical Work Plan. Neither ADCT nor Genmab shall be required to undertake any activity relating to the Development of the ADC that it believes, in good faith, may violate any applicable law. The Parties acknowledge and agree that neither Party guarantees the success of the Development tasks undertaken hereunder.

6.4 Development Costs. The Parties will share equally all Development Costs for the ADC (which have been set forth in the Clinical Work Plan) with respect to the Development activities hereunder. The Parties are obligated to each fund [**] of costs associated with the Development of the ADC up until the final report for the Qualifying Phase I/II Clinical Trial. The JSC shall review on a [**] basis the Development Costs against the budget for such expenses in the applicable calendar year. If in the course of such [**] review the JSC determines that the actual amounts incurred for Development Costs are likely to be higher than budgeted, the JSC shall review the reasons for such potential overrun and determine whether such overrun is appropriate. The JSC may, if appropriate, amend the Clinical Work Plan to permit such overrun or to reduce such activities such that no overrun is incurred. If any costs for the Development activities result in a budget overrun of the applicable and approved annual joint budget in excess of [**], the JSC shall have the discretion to review such costs and designate them as Development Costs. Where the JSC does not so designate excess Development Costs, any such unapproved excess Joint Development Costs shall be borne by the Party incurring them. However, if the budget overrun is due to a delay or an advance in timing as to the planned activities, which activities are in accordance with the Clinical Work Plan, then such excess Development Costs shall be shared equally by the Parties regardless of which Party has incurred such costs. ADCT agrees at payments under the Spirogen Agreement, if any, shall not be part of the Development Costs and shall be borne solely by ADCT.

6.5 FTE Rate. The Parties agree that the mutual annual rate per FTE of either Party who performs Development, consultation or support work for the ADC as set forth in the Clinical Work Plan and to be used when calculating the Development Costs is [**]. Commencing upon the [**] anniversary of the Effective Date and upon every anniversary thereafter, the fee will be adjusted in accordance with the percentage change over the applicable annual period in the Harmonized Index of Consumer Prices, UK.

(b) The Development Cost Reports will be in such form as the JSC may reasonably agree from time to time.

(c) Within [**] days of the receipt of both Parties’ Development Cost Reports, the JSC (or a Party’s Finance Manager or accountancy firm appointed by the JSC) shall provide to each Party one consolidated financial report for the Development Costs. The total costs incurred by both Parties shall be divided equally, with a subsequent balancing payment by one Party to the other to the extent necessary so that each Party bears its appropriate share of such Development Costs. The Party that is due for reimbursement of Development Costs in the preceding Calendar Quarter shall invoice the other Party. Such balancing payments by one Party to reimburse the other Party’s expenditures for Development Costs for the purposes of cost sharing under this Agreement shall be paid within [**] days following receipt of the invoice. Genmab shall be entitled to deduct from any payments to ADCT, its Out-of-Pocket Expenses to hedge currency risk pursuant to Section 6.7.2. In the event that Parties disagree with the reported costs and any over/under spend, approval shall be required by the JSC following receipt of the report by the JSC. A decision by the JSC shall be required within [**] days following its receipt of the consolidated report. Based on the JSC’s decision the Party due for reimbursement shall invoice the other Party and payment shall be made within [**] days of receipt of the invoice. Where the JSC does not so agree with the reported costs or over/under spend, any such unapproved spend can be referred to dispute resolution procedures provided in Article 16 by the Party having incurred such spend.

(d) The Parties should provide proper support for expenses included on the invoice. Reasonable support documents for Out-of-Pocket Expenses include invoice or pro forma invoice from the Third Party vendors or subcontractors. For FTE reimbursement, proper support includes an FTE time report breakdown by function.

Where there is a payment to be made between the Parties to equilibrate expenditures under this Agreement, such payments shall be made in United States Dollars, assuming that the amount due was incurred on a straight line basis in the period between the last equilibration payment and the payment currently due. A cost equivalent to the Out-of-Pocket Expenses, if any, of hedging the exchange rate risk for this period may be claimed by Genmab at a rate equal to the USD:Euro [**] forward rate published in the Financial Times during such period plus a margin of [**] of that rate.

6.8 Audits and Records. Upon the written request of a Party (the “Requesting Party”) and not more than [**] in each calendar year, the other Party (the “Responding Party”) will permit an independent certified public accounting firm of national recognized standing, selected by the Requesting Party and reasonably acceptable to the Responding Party, at the Requesting Party’s expense, to have access during normal business hours to the records of the Responding Party as may be reasonably necessary to verify the accuracy of the reports provided under Section 6.6.1, for any year ending not more than [**] prior to the date of such request. The Parties shall maintain for at least [**] accurate books and records which enable the verification of the Development Costs incurred by the Parties, and any other payment made, or cost incurred, by the Parties for which the other Party is responsible for reimbursement of its share under this Agreement.

6.9 Other Payments. Unless otherwise expressly set forth to the contrary in this Agreement, payment due from one Party to another under this Agreement shall be paid within [**] days of receipt of invoice or from a date specified in the Agreement, whichever is earlier. For the avoidance of doubt, failure to make any payment herein shall be a material breach of the Agreement.

6.10 Withholding Taxes. Except as provided to the contrary in this Agreement, any taxes, levies or other duties paid or required to be withheld or deducted under the appropriate laws by one of the Parties on account of monies payable to the other Party under this Agreement shall be deducted from the amount of monies otherwise payable to the other Party under this Agreement.

The withholding Party shall secure and send to the other Party within a reasonable period of time proof of any such taxes, levies or other duties paid or required to be withheld by the withholding Party for the benefit of the other Party. The Parties shall cooperate reasonably with each other to ensure that any amounts required to be withheld by either Party are reduced in an amount to the fullest extent permitted by Law. Any penalties or other charges imposed by a governmental authority as a result of a failure by the withholding party to pay such taxes, levies or other duties shall be the responsibility of the withholding party. The other Party will give the withholding Party any information necessary to determine such taxes, levies or other duties. No deduction shall be made, or a reduced amount shall be deducted, if the other Party furnishes a document from the appropriate governmental authorities to the withholding Party certifying that the payments are exempt from such taxes, levies or other duties or subject to reduced tax rates, according to the applicable convention for the avoidance of double taxation.

Accordingly, where any taxable supply for VAT purposes is made under or in connection with this Agreement by one Party to the other, the recipient of that supply shall, in addition to any payment for that supply, pay to the supplier such VAT as is chargeable in respect of the supply at the same time as payment is due or in any other case when demanded by the supplier.

6.12 Interest on Late Payments. If a Party shall fail to make a payment pursuant to this Agreement when due, any such late payment shall bear interest, to the extent of prohibited by Law, at the annual rate of [**] per annum above LIBOR, effective for the first date on which payment was delinquent and calculated on the number of days such payment is overdue.

Article 7
UNILATERAL DEVELOPMENT

7.1 Development Under the 25% Election or after a Withdrawal by Genmab. If Genmab makes the 25% Election or a later Withdrawal, ADCT shall be the sole developing Party, and be solely responsible for executing and funding the Clinical Work Plan, as approved and modified by the JSC from time to time, until the completion of the Qualifying Phase I/II Clinical Trial. The members of the JSC appointed by ADCT shall have the casting vote on the JSC.
