All funds deposited with the Escrow Agent shall be applied by the Escrow Agent in accordance with the Escrow Agreement. AbbVie shall pay the remaining balance of the upfront payment to Kadmon on the Effective Date by wire transfer of immediately available funds to a bank account designated by Kadmon.

(An illustrative example of the calculation of the Royalty Payment is set forth on Schedule 6.3.1.) Following the Royalty Term, no additional Royalty Payment shall be due and owing except for any Royalty Payment that was accrued but unpaid during such Royalty Term. Notwithstanding the foregoing or anything to the contrary herein, (a) no Royalty Payment will be due and owing for the Co-Packaged Bid Product if AbbVie no longer has the right to reference or use the abbreviated new drug application number 077-456 (the “ANDA”), including if the ANDA is revoked, and (b) in the event that Kadmon has obtained Regulatory Approval for the QD Product, for purposes of this Section 6.3.1, “Exclusive Product” will include, for so long as AbbVie has the right to reference or use the Regulatory Approval covering such QD Product, any product containing (i) a single immediate release standalone tablet (and specifically excluding capsules) formulated (whether or not by or on behalf of Kadmon or whether or not using Kadmon Know-How) to contain the entire daily Ribavirin dose of 600mg, 800 mg, 1000mg, or 1200mg, as applicable, for patients and (ii) any other approved drug, in separate final dosage forms, packaged together with appropriate labeling, intended for use together for the ease of the patient.

Any amounts payable by AbbVie under this Section 6.3.1 shall be due and payable within *** (***) days after the end of each Calendar Quarter.

6.3.3. At any time during the Royalty Term, the Royalty Payment due for any Co-packaged BID Product having a 400mg or greater dose of Ribavirin (such 400mg or greater dose of Ribavirin, the “High Dose BID Product”) shall be reduced by eighty percent (80%) in the event one or more Third Parties commercializes in the Territory (a) a High Dose BID Product and (b) such Third Party(ies)’ High Dose BID Product(s) achieve a twenty-five percent (25%) market share by unit sales (as determined by IMS Health or other reputable source) for such High Dose BID Product(s).

6.3.5. The reduction of the Royalty Payments as described in Sections 6.3.3 and 6.3.4 shall not take effect until the first day of the Calendar Quarter next following the Calendar Quarter during which the matters described in (a) Sections 6.3.3(a) and (b); or (b) Sections 6.3.4(a) and (b), as applicable, first occur.

6.4. Withholding. Notwithstanding any other provision of this Agreement, AbbVie shall be entitled to withhold, or cause to be withheld, any and all amounts paid or deemed paid by it to any Person as a result of the transactions contemplated by this Agreement, that it reasonably believes are required to be withheld under Applicable Law. To the extent such amounts are so deducted and withheld and paid over to the applicable Governmental Authority, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid and the payor Party shall secure and send to the payee Party evidence in its possession of such payment.

6.5. Records and Audits.

6.5.1. Each Party and its Affiliates shall maintain complete and accurate books and records of account, in accordance with generally accepted accounting principles in the United States, of all transactions and other business activities under this Agreement, sufficient to confirm the accuracy of all reports furnished by a Party to the other Party under this Agreement, and all payments by a Party to the other Party

under this Agreement. Upon reasonable written notice to a Party, but no more often than once per Calendar Year, such Party shall permit, and shall cause its Affiliates to permit, an independent certified public accountant of national standing designated by the other Party to audit such books and records of account of such Party and its Affiliates, in order to confirm the accuracy and completeness of all such reports and all such payments. The accounting firm shall disclose to the Party requesting the audit only whether the audited reports are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided to the Party requesting the audit.

6.5.2. The Party requesting an audit shall bear all costs and expenses incurred in connection with any such audit; provided, however, that if any such audit correctly identifies any underpayments by the audited Party hereunder or overpayments by the auditing Party that are the fault of the audited Party hereunder in excess of ***% of the amount actually payable by such Party to the Party requesting the audit hereunder, or ***, whichever is greater, then, in addition to paying the full amount of such underpayment or overpayment, plus accrued interest in accordance with Section 6.7, the audited Party shall reimburse the other Party for all reasonable costs and expenses incurred by such Party in connection with that audit. In the event that such audit reveals an overpayment by the audited party, or an underpayment by the auditing Party, the auditing Party shall promptly refund any such overpayment or pay to the audited Party the amount of such underpayment, as applicable.

6.5.3. The audited Party shall not be required to maintain books and records for more than two (2) years following the end of any Calendar Year.

6.5.4. The Party requesting an audit shall treat all financial information subject to review under this Article 6 in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with the audited Party and/or its Affiliates obligating it to retain all such information in confidence pursuant to such confidentiality agreement, unless the accounting firm is already subject to confidentiality obligations by virtue of its professional engagement with the Party being audited in which case a separate confidentiality agreement shall not be required.

6.6. Currency. All payments to be made by a Party under this Agreement shall be paid in USD, by wire transfer, pursuant to the instructions of Kadmon, as designated from time to time at least seven (7) Business Days prior to the date payment is due.

6.7. Late Payment. In the event that any payment is not paid in accordance with the provisions of this Article 6, the overdue amount shall bear interest, at a rate equal to the Fed (U.S.) Prime Rate, as of the date such payment is due, per annum, or, if lower, the maximum rate permitted under Applicable Law, as of the date the payment is due, until the entire unpaid overdue amount shall have been paid in full.

7.2. Alternative Supply Arrangements. In accordance with the Supply Agreement, Kadmon shall use Commercially Reasonable Efforts to facilitate AbbVie establishing itself or a Third Party as an alternate manufacturer of Product to supply AbbVie’s worldwide requirements for Product beyond the Supply Agreement Requirements Obligation (including in the event of circumstances in which Kadmon’s supply is interrupted and Kadmon is unable to fulfill the Supply Agreement Requirements Obligation).

8.1.1. Kadmon shall use Commercially Reasonable Efforts to secure and protect the Kadmon Patent Rights, at its own cost, including, filing and prosecuting any patent applications and maintaining any patents within the Kadmon Patent Rights; provided, however, that Kadmon may at any time decline to undertake or continue such prosecution or maintenance of Kadmon Patent Rights. If Kadmon elects not to file, prosecute or maintain any Kadmon Patent Rights in the Territory, Kadmon shall provide written notice, within a reasonable period of time (which in any event will not be less than ninety (90) days prior to the next action or payment due date required to keep such Kadmon Patent Right in full force and effect), of such election to AbbVie and, in the event AbbVie so elects, shall assign such rights to AbbVie and shall execute such documents and perform such acts as may be reasonably necessary to so assign such rights to AbbVie and such Patent Rights shall cease to be Kadmon Patent Rights.

8.1.2. Kadmon shall have the first right to control any interference, opposition, post-grant review, reexamination and similar proceedings relating to Kadmon Patent Rights claiming the Product. AbbVie shall be provided prompt notice of the institution of such proceedings, or the intent to institute such proceedings, within a reasonable period of time, and shall provide AbbVie advance copies of any documents related thereto for review and comment; provided, however, that the final decision with respect thereto shall rest with Kadmon.

8.1.3. Without limiting the foregoing, AbbVie shall be copied on all filings and correspondence to, and Kadmon shall promptly provide to AbbVie copies of all correspondence received from, the USPTO regarding Kadmon Patents Rights covering, including disclosing and/or claiming, the QD Product.

8.2.1. Each Party shall promptly report in writing to the other Party during the Term any (a) known or suspected infringement of any Kadmon Patent Rights, or (b) unauthorized use of any Kadmon Know-How, of which such Party becomes aware (“Infringement”).

available evidence supporting such infringement, suspected infringement, unauthorized use or suspected unauthorized use. Promptly after receipt of a notice of Infringement, the Parties shall discuss in good faith the infringement and appropriate actions that could be taken to cause such infringement to cease.

8.2.2. Kadmon shall have the first right to initiate a suit or take other appropriate action that it believes is reasonably required to protect the Kadmon Know-How or the Kadmon Patent Rights claiming the Product in the Territory against any Infringement. If Kadmon decides not to initiate a suit or take other appropriate action with respect to any such Infringement in the Territory, AbbVie may undertake such actions, in which case Kadmon shall, and shall cause its Affiliates to, cooperate with AbbVie in its efforts to initiate a suit or take other appropriate action with respect to any Infringement in the Territory and shall agree to be parties in any suit, if requested.

8.2.3. Without regard to which Party initiates a suit or takes other appropriate action with respect to any Infringement in the Territory under Section 8.2.2, all costs (including all reasonable costs and expenses associated with any defense of a claim hereunder) associated with any such action in the Territory, and any costs and expenses incurred by any Party or its Affiliates with respect to any Infringement shall be the sole responsibility of the Party initiating the action. Any proceeds from such actions shall be allocated between the Parties first to compensate each Party on a pro rata basis for amounts it incurred in pursuing such actions and second to the Party instituting the action.

8.2.4. The enforcing Party under Section 8.2.2 shall have the sole and exclusive right to select counsel for any suit initiated by it. If required under Applicable Law in order for such enforcing Party to initiate and/or maintain such suit or action, the other Party shall join as a party to the suit or action. Such other Party shall offer reasonable assistance to such enforcing Party in connection therewith at such enforcing Party’s cost and expense.

8.3. Patent Infringement Claims Against Kadmon and/or AbbVie.

8.3.1. In the event of the institution of any infringement claim against either Party as a result of any claim made or brought by any Third Party that the manufacture, use, sale or other Commercialization of the Product infringes, misappropriates or otherwise conflicts with the Patent Rights or any other intellectual property rights of any Third Party (“Infringement Claim”), the Party first having notice shall as soon as reasonably practicable notify the other Party.

8.3.2. AbbVie shall have the first right to defend the Parties and their Affiliates against an Infringement Claim. Kadmon shall, and shall cause its Affiliates to, reasonably cooperate with AbbVie at Kadmon’s own expense in its efforts to defend against such Infringement Claim if requested, and shall agree to be a party in any suit, if requested by AbbVie. Further, Kadmon shall have a right, in Kadmon’s sole discretion and at Kadmon’s sole expense, to join or otherwise participate in such legal action with legal counsel selected by Kadmon; provided, however, that such participation shall not undermine AbbVie’s right to control such legal action.

AbbVie shall notify and keep Kadmon apprised in writing of such action. Any settlement of such Infringement Claim that would admit liability on the part of Kadmon or any of its agents or Affiliates shall be subject to Kadmon’s prior written approval, which approval will not be unreasonably withheld, conditioned or delayed. If AbbVie decides not to pursue defense of any such Infringement Claim, Kadmon may defend such Infringement Claim, in which case AbbVie shall, and shall cause its Affiliates to, cooperate fully with Kadmon in its efforts to defend such Infringement Claim and shall agree to be parties in any suit, if requested. Any settlement of such Infringement Claim that would admit liability on the part of AbbVie or any of its agents or Affiliates shall be subject to AbbVie’s prior written approval, such approval to be granted or withheld by AbbVie in its sole discretion. Without regard to which Party defends an Infringement Claim under this Section 8.3.2, all damages in excess of the Deductible (as defined in Section 11.4 hereof), including all reasonable costs and expenses associated with any defense of a claim hereunder, associated with any such Infringement Claim, and any costs and expenses incurred by any Party or its Affiliates to obtain a license or otherwise settle any Infringement Claim, shall be the sole responsibility of Kadmon and Kadmon shall promptly reimburse any costs and expenses incurred by AbbVie with respect thereto in excess of the Deductible; provided, however, that (a) if the amounts paid or contractually required to be paid by Kadmon under this Section 8.3.2, under Section 8.3.3 or Section 11.2 for purposes of obtaining a license or otherwise settling any Infringement Claim(s) (including amounts for defense costs), exceeds ten million dollars (US$10,000,000) in the aggregate after taking into consideration the Deductible, then AbbVie shall obtain the prior written consent of Kadmon, which consent shall not be unreasonably withheld or delayed, prior to paying or agreeing to pay such amounts in connection with obtaining any such license or settling any such Infringement Claim(s); and (b) AbbVie shall obtain Kadmon’s prior written consent, which consent shall not be unreasonably withheld or delayed, for any settlement or licensing that involves any agreement or commitment imposing any affirmative obligation or restriction on the part of Kadmon, other than the payment of money on terms consistent with this Section 8.3.2.

8.3.3. If, during the Term, a Party believes it is necessary to seek a license from any Third Party in order to avoid or settle an Infringement Claim during the exercise of the rights herein granted, whether or not there has been the institution of any Infringement Claim, such Party shall notify the other Party. In the event AbbVie determines itself that it would be advisable to obtain such a license, then AbbVie shall have the right, at its sole discretion, to obtain such a license; provided, however, that if the amounts paid or contractually required to be paid by Kadmon under Section 8.3.2, under this Section 8.3.3 and Section 11.2 for purposes of obtaining a license or otherwise settling any Infringement Claim(s) (including amounts for defense costs), exceeds ten million dollars (US$10,000,000) in the aggregate after taking into consideration the Deductible, then, AbbVie shall obtain the prior written consent of Kadmon, which consent shall not be unreasonably withheld or delayed, prior to paying or agreeing to pay any such amounts in connection with obtaining any such license or settling any such Infringement Claim(s). Subject to the preceding sentence, all costs and expenses incurred by either Party associated with obtaining and maintaining a license shall be deemed

Existing Third Party Royalties and shall be the sole responsibility of Kadmon in accordance with Section 8.5.

8.4. Maintenance and Protection of the QD Product Trademark and AbbVie Product Xxxx.

8.4.1. Kadmon agrees to maintain, at its sole cost and expense, the QD Product Trademark in the Territory. Kadmon shall give notice to AbbVie of any decision by Kadmon to cease its maintenance of any such trademark. If Kadmon elects not to maintain any such trademark, AbbVie may, but is not required to, provide notice to Kadmon that AbbVie desires to maintain such trademark. If AbbVie elects to continue maintenance, then Kadmon shall assign such trademark to AbbVie and Kadmon shall execute such documents and perform such acts as may be reasonably necessary to so assign such trademark to AbbVie and from and after such assignment such trademark shall cease to be a QD Product Trademark and shall become an AbbVie Product Xxxx.

8.4.2. Kadmon shall have the first right to initiate a suit or take other appropriate action that it believes is reasonably required to protect the QD Product Trademark in the Territory against any Third Party who either infringes any such trademark or brings claims or proceedings against either or both of the Parties for infringement of the Third Party’s trademarks in relation to the use of such trademark. Further, AbbVie shall have a right, in AbbVie’s sole discretion and at AbbVie’s sole expense, to join or otherwise participate in such legal action in the Territory with legal counsel selected by AbbVie; provided, however, that such participation shall not undermine Kadmon’s right to control such legal action. Kadmon shall notify and keep AbbVie apprised in writing of such action and shall consider and take into account AbbVie’s reasonable interests and requests regarding such action. Any settlement of such an action that would admit liability on the part of AbbVie, or impose any obligation on AbbVie, or any of its agents or Affiliates shall be subject to AbbVie’s prior written approval, such approval to be granted or withheld by AbbVie in its sole discretion. If Kadmon decides not to pursue or defend any such action in the Territory, AbbVie may pursue or defend such action, in which case Kadmon shall, and shall cause its Affiliates to, cooperate fully with AbbVie in its efforts to pursue or defend such action and shall agree to be parties in any suit, if requested. Any settlement of such an action that would admit liability on the part of Kadmon or any of its agents or Affiliates shall be subject to Kadmon’s prior written approval, which approval will not be unreasonably withheld, conditioned or delayed. Without regard to which Party pursues or defends such action under this Section 8.4.2, all damages (including all reasonable costs and expenses associated with any defense of a claim hereunder) associated with any such action in the Territory shall be the sole responsibility of Kadmon and Kadmon shall promptly reimburse any costs incurred by AbbVie with respect thereto.

8.4.3. The rights and obligations of the Parties set forth in Sections 8.4.1 and 8.4.2 shall be in effect under this Agreement until such time, if ever, that Kadmon transfers and assigns the QD Product Trademark to AbbVie or its designee pursuant to Section 8.4.1. Upon such assignment, the QD Product Trademark shall be considered an AbbVie Product Xxxx and Kadmon shall cease to have any rights or interests to the

QD Product Trademark.

8.4.4. AbbVie shall have sole discretion with respect to the maintenance, enforcement and defense of the AbbVie Product Marks and Kadmon shall have no rights with respect to the AbbVie Product Marks (except those rights which may be granted in the Supply Agreement to permit Kadmon (or Kadmon’s supplier) to apply the AbbVie Product Marks to Product being supplied to AbbVie).

8.5. Existing Third Party Royalties. Kadmon shall be solely responsible for, and shall otherwise pay promptly when due, all Existing Third Party Royalties; provided, that, if Kadmon fails to pay Existing Third Party Royalties, then Kadmon shall promptly provide AbbVie with copies of any demand Kadmon receives for payment regarding such Existing Third Party Royalties, and AbbVie shall have the right to make such payment on behalf of Kadmon. In such event, Kadmon shall promptly reimburse AbbVie any documented amounts paid by AbbVie or, at AbbVie’s election, AbbVie may offset such amounts paid by AbbVie against the Royalty Payments to be made by AbbVie to Kadmon.

9. CONFIDENTIAL INFORMATION.

9.1. Confidentiality Obligations. All Confidential Information disclosed by one Party to the other Party hereunder shall, during the Term, be maintained in confidence by the receiving Party and shall not be disclosed to Third Parties nor used for any purpose except to perform the receiving Party’s obligation or exercise the receiving Party’s rights pursuant to and in accordance with this Agreement, without the prior written consent of the disclosing Party. Both Parties shall require employees to whom Confidential Information is disclosed to undertake confidentiality and non-use obligations at least as restrictive as the terms of this Article 9.

protect the confidentiality of such Confidential Information;

f) is necessary to be disclosed to Affiliates, agents, consultants, and/or other Third Parties inside or outside the Territory for the research and development, manufacturing and/or marketing of Product (or for such entities to determine their interest in performing such activities) for sale or use in the Territory in accordance with this Agreement on the condition that such Affiliates and/or Third Parties agree to be bound by the confidentiality and non-use obligations contained in this Agreement; or

g) to the extent required by Applicable Law (including in connection with any securities reporting obligations of the United States Securities and Exchange Commission (SEC) or stock market on which the receiving Party is listed) or court order; provided, however, that the recipient promptly provides to the disclosing Party prior written notice of such disclosure and provides reasonable assistance in obtaining an order or other remedy protecting the Confidential Information from public disclosure.

9.2. Injunctive Relief. In the event of any unauthorized use or disclosure by either Party of any of the other Party’s Confidential Information, the other Party shall be entitled to seek preliminary and permanent injunctive relief, as provided under Applicable Law, to prevent or enjoin any such unauthorized use or disclosure of any of the other Party’s Confidential Information.

9.3. Public Disclosures. No disclosure of the existence, or the terms, of this Agreement may be made by either Party, and no Party shall use the name, trademark, trade name or logo of the other Party, its Affiliates or their respective employee(s) in any publicity, promotion, press release or disclosure relating to this Agreement or its subject matter, without the prior express written permission of the other Party, except as may be required by Applicable Law. Notwithstanding the foregoing, the Parties have agreed to (a) permit public disclosure of the transactions contemplated by this Agreement strictly in accordance with the agreed upon language set forth on Schedule 9.3 (provided that in no event shall Kadmon issue any press release or similar public statement or disclosure except as provided in Section 9.3(b) and (c)), (b) allow disclosure of this Agreement and the Ancillary Agreements to each Party’s insurers and to existing or potential equity investors and debt providers, provided that such Third Parties are bound by confidentiality restrictions at least as stringent as those contained in Section 9.1, and (c) allow disclosure of the existence of this Agreement to its field employees and vendors and for internal communications.

AbbVie shall have the right to make such publications as it chooses, in its sole discretion, subject to the review rights of Kadmon as set forth in this Section 9.4. The Party wishing to make a publication or presentation regarding the Product shall submit to the other Party any publication or presentation

(including in any seminars, symposia or otherwise) of information related directly or indirectly to the Product for review and, in the case of a publication proposed by Kadmon, approval, at least ninety (90) days prior to submission of the publication or presentation. The reviewing Party shall have the right (a) solely in the case that AbbVie is the reviewing Party, to propose modifications to the publication or presentation for patent reasons, trade secret reasons or business reasons or (b) to request a reasonable delay in publication or presentation in order to protect patentable information. If the reviewing Party requests modifications to the publication or presentation, the publishing Party shall edit such publication to prevent disclosure of trade secret or proprietary business information prior to submission of the publication or presentation. If the reviewing Party requests a delay, the publishing Party shall delay submission or presentation for a period of ninety (90) days to enable patent applications protecting each Party’s rights in such information to be filed. Notwithstanding the foregoing right of Kadmon to review (but not approve) AbbVie publications or presentations regarding the Product, if the planned publication or presentation does not include any Confidential Information of Kadmon, then AbbVie shall have no obligation to submit such publications or presentations to Kadmon for review.

11. INDEMNIFICATION AND INSURANCE.

11.1. By AbbVie. AbbVie shall indemnify, defend and hold harmless Kadmon, its Affiliates and their respective employees, officers, directors and agents (“Kadmon Indemnitees”) from and against any and all Losses that the Kadmon Indemnitees directly incur, and all Losses that the Kadmon Indemnitees actually pay to one or more Third Parties (whether such claim is asserted as a tort, breach of contract or otherwise), in each instance to the extent resulting from or arising out of (a) any breach by AbbVie of any of its representations, warranties or obligations pursuant to this Agreement, (b) AbbVie’s or its Affiliates’ negligence (or more culpable act or omission) or violation of Applicable Laws or regulations in performing or failing to perform its rights or obligations in connection with this Agreement or (c) the development, manufacture, use or Commercialization of Product by or on behalf of AbbVie and/or its Affiliates in the Territory (except for matters conducted solely by Kadmon under this Agreement or the Ancillary Agreements); provided, however, that AbbVie will not be obligated to indemnify or hold harmless Kadmon Indemnitees from any such Losses to the extent resulting from (i) any breach by Kadmon of any of its representations, warranties or obligations pursuant to this Agreement, (ii) Kadmon’s or its Affiliates’ negligence (or more culpable act or omission) or violation of Applicable Laws or regulations in performing or failing to perform its rights or obligations in connection with this Agreement, (iii) any claim made or brought by any Third Party that the manufacture, use, sale or other Commercialization of the Product infringes, misappropriates or otherwise conflicts with the Patent Rights or any other intellectual property rights of any Third Party, or (iv) any claim made or brought by any Third Party that the execution and delivery of this Agreement or the grant of any of the rights under this Agreement to AbbVie conflicts with or otherwise tortiously interferes with the rights of any other Third Party.

11.2. By Kadmon. Kadmon shall indemnify, defend and hold harmless AbbVie, its Affiliates and their respective employees, officers, directors and agents (“AbbVie Indemnitees”) from and against any and all Losses that the AbbVie Indemnitees directly

incur, and all Losses that the AbbVie Indemnitees actually pay to one or more Third Parties (whether such claim is asserted as a tort, breach of contract or otherwise), in each instance to the extent resulting from or arising out of (a) any breach by Kadmon of any of its representations, warranties or obligations pursuant to this Agreement, (b) Kadmon’s or its Affiliates’ negligence (or more culpable act or omission) or violation of Applicable Laws or regulations in performing or failing to perform its rights or obligations in connection with this Agreement, (c) the development, manufacture, use or Commercialization of Product by or on behalf of Kadmon and/or its Affiliates or licensees (except for matters conducted solely by AbbVie under this Agreement or the Ancillary Agreements), (d) any claim made or brought by any Third Party that the manufacture, use, sale or other Commercialization of the Product infringes, misappropriates or otherwise conflicts with the Patent Rights or any other intellectual property rights of any Third Party, or (e) any claim made or brought by any Third Party that the execution and delivery of this Agreement or the grant of any of the rights under this Agreement to AbbVie conflicts with or otherwise tortiously interferes with the rights of any other Third Party; provided, however, that Kadmon will not be obligated to indemnify or hold harmless AbbVie Indemnitees from any such Losses to the extent resulting from (i) any breach by AbbVie of any of its representations, warranties or obligations pursuant to this Agreement or (ii) AbbVie’s or its Affiliates’ negligence in performing its obligations under this Agreement (or more culpable act or omission) or violation of Applicable Laws or regulations in performing or failing to perform its rights or obligations in connection with this Agreement.

11.3. Claims for Indemnification. A Party entitled to indemnification under this Article 11 (an “Indemnified Party”) shall give prompt written notification, with sufficient detail to allow the receiving Party to make an assessment thereof, to the Party from whom indemnification is sought (the “Indemnifying Party”) of the commencement of any action, suit or proceeding relating to a Third Party claim for which indemnification may be sought or, if earlier, upon the assertion of any such claim by a Third Party (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a Third Party claim as provided in this Section 10.3 shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually damaged as a result of such failure to give notice). Except with respect to indemnification claims pursuant to Section 11.2(d), in which case AbbVie shall have the first right to assume the defense of such claim in accordance with Section 8.3.2, within fourteen (14) days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such action, suit, proceeding or claim with counsel reasonably satisfactory to the Indemnified Party. If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party shall reimburse the Indemnified Party for all reasonable and documented costs, including attorney fees, incurred by the Indemnified Party in defending itself within thirty (30) days after receipt of any invoice therefore from the Indemnified Party. The Party not controlling such defense may monitor and participate in the controlling Party’s defense at its own expense; provided that, if the Indemnifying Party assumes control of such defense and the Indemnified Party in good faith concludes, based on advice from counsel, that the

Indemnifying Party and the Indemnified Party have conflicting interests with respect to such action, suit, proceeding or claim, the Indemnifying Party shall be responsible for the reasonable fees and expenses of separate counsel to the Indemnified Party in connection therewith. The Party controlling such defense shall keep the other Party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other Party with respect thereto. The Party not controlling such defense shall cooperate with the controlling Party and shall make available to the controlling Party all witnesses, information and materials in such Party’s possession or under such Party’s control relating thereto as are reasonably required by the controlling Party, subject to appropriate provisions for the protection of confidentiality. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that is not solely for monetary damages, that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party, or that acknowledges fault by the Indemnified Party without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld.

11.4. Limitation. No claim may be made by any AbbVie Indemnitee for indemnification pursuant to Section 11.2 or 8.3.2 unless and until the aggregate amount of Losses for which all AbbVie Indemnitees seek to be indemnified exceeds *** (the “Deductible”), in which case Kadmon shall be liable only for such Losses in excess of the Deductible and, in any event, all AbbVie Indemnitees shall first seek recovery from the Escrow Amount before seeking recovery directly from Kadmon with respect to any indemnification claim pursuant to Sections 11.2 or 8.3.2 hereof.

11.5. Insurance.

11.5.1. Kadmon and its Affiliates shall, at their sole cost and expense, obtain and maintain in full force and effect commercial general liability insurance, which complies with all Applicable Laws of the Territory, and provides for minimum loss coverage at least *** and product liability insurance, which complies with all Applicable Laws of the Territory, and provides for minimum loss coverage at least ***. Kadmon hereby specifically acknowledges and agrees that this Article shall not be construed to create any limit on Kadmon’s liability hereunder and/or indemnification obligation under Section 11.2 hereof. As soon as practicable following the Effective Date and following the receipt from AbbVie of information required by Kadmon’s insurer for such purpose, Kadmon shall cause AbbVie to be named as additional insured under Kadmon’s commercial general liability insurance policy. The Parties agree that for the purposes of this Section 11.5 Kadmon shall be permitted to provide this Agreement and any Ancillary Agreement to its insurer.

11.5.2. Any Losses as to which indemnification provided for in Sections 11.1 and 11.2 may apply shall be determined net of any cash recovery actually received by an Indemnified Party with respect to insurance specifically with respect to the specific

matter for which indemnification is sought, less any costs actually incurred in obtaining such recovery (including premium adjustments and similar charges).

11.5.3. AbbVie and its Affiliates shall, at their sole cost and expense, obtain no later than the date of first commercial sale of Product in the Territory by or on behalf of AbbVie, and shall maintain in full force and effect commercial general liability insurance, which shall provide product liability coverage which complies with all Applicable Laws of the Territory, and provides for minimum loss coverage at least equal to the insurance coverage maintained by AbbVie with respect to AbbVie’s and its Affiliates’ proprietary pharmaceutical products. AbbVie hereby specifically acknowledges and agrees that this Article shall not be construed to create any limit on AbbVie’s liability hereunder and/or indemnification obligation under Section 11.1 hereof. Kadmon acknowledges and agrees that AbbVie may satisfy its obligations under this Section 11.5.3 through a self-insurance program.

11.6. Escrow Instructions. In the event that any claim for indemnification under this Agreement is made against the Escrow Amount that is subject to an alternative dispute resolution proceeding pursuant to Schedule 14.6, then in the event a final order is rendered pursuant to such dispute procedure relating to the liability of either Party, the Parties shall deliver to the Escrow Agent a joint written instruction authorizing the release of the applicable portion of the Escrow Amount in accordance with such final order.

12. TERM AND TERMINATION.

12.1. Term. This Agreement shall enter into effect on the Effective Date hereof, and unless terminated earlier in accordance with the terms of this Agreement, shall remain in full force and effect in perpetuity with respect to the license grants (the “Term”).

12.3. Termination Related to Bankruptcy or Similar Action. Kadmon or AbbVie, as the case may be, shall have the right to terminate this Agreement, immediately upon giving written notice of termination to the other Party, in the event that the other Party files a voluntary petition, or suffers the filing of a substantiated involuntary petition under the bankruptcy provisions of Applicable Law which is not dismissed within ninety (90) days of its filing, is declared insolvent, undergoes voluntary or involuntary dissolution, makes an assignment for the benefit of creditors, fails or is unable to pay its debts as they come due, or suffers the appointment of a receiver or trustee over all, or substantially all, of its assets or properties.

12.4. Termination for Material Breach. In the event that either Party to this Agreement (the “breaching Party”) commits a material breach or default of any of its obligations hereunder, the other Party hereto (the “non-breaching Party”) may give the breaching Party written notice of such breach or default. In the event that the breaching Party fails to cure such breach or default within ninety (90) days after the date of the

non-breaching Party’s notice thereof, or if such breach or default cannot be cured within ninety (90) days after the date of the non-breaching Party’s notice thereof, then the non-breaching Party may terminate this Agreement immediately; provided, that, notwithstanding the foregoing, Kadmon’s right to terminate this Agreement under this Section 12.4 shall be a remedy of last resort and may be invoked only in the case where the breach cannot be reasonably remedied by the payment of monetary damages or other remedy under Applicable Law. Termination under this Section 12.4 shall only become effective after resolution of any dispute for which termination is being sought.

13. CONSEQUENCES OF TERMINATION.

13.1. Termination by AbbVie or the Parties Jointly Under Section 12.2 or by a Party Under Section 12.3 or 12.4. Upon the effective date of termination of this Agreement following termination by AbbVie or the Parties jointly under Section 12.2 or by a Party under Section 12.3 or 12.4:

13.1.1. all licenses and all rights granted to AbbVie under this Agreement shall terminate;

13.1.2. notwithstanding Section 13.1.1, AbbVie and its Affiliates shall be entitled, during the eighteen (18) month period following such effective date of termination, to sell any inventory of Product which remains on hand, or in the manufacture and supply pipeline, as of the effective date of the termination, in all cases in accordance with the terms and conditions set forth in this Agreement which shall be deemed to survive for such eighteen (18) month period for the purpose of this Section 13.1.2. In the event that this Agreement is terminated by AbbVie under Sections 12.3 or 12.4 and any inventory remains following such eighteen (18) month period, then Kadmon shall purchase such inventory at AbbVie’s cost of goods, plus ***.

13.2. Discontinuation of Use; Return of Confidential Information. Except for rights granted pursuant to this Article 13, upon expiration or termination of this Agreement, each Party will discontinue use of the other Party’s Confidential Information and will return to the other Party (unless otherwise mutually agreed in writing by the Parties and except for one copy for archival purposes only) within thirty (30) days after the effective date of expiration or termination all physical embodiments of any of the other Party’s Confidential Information, that were provided by such other Party under this Agreement.

13.3. Bankruptcy.

13.3.1. If this Agreement is terminated by either Party pursuant to Section 12.3 due to the rejection of this Agreement by or on behalf of the other Party or such other Party’s “affiliate” (as defined pursuant to the Code) (the “Bankrupt Party”) under Article 365 of the United States Bankruptcy Code (the “Code”), all licenses and rights to licenses granted under or pursuant to this Agreement by the Bankrupt Party to the other Party (the “Licensing Party”) are, and shall otherwise be deemed to be, for purposes of Article 365(n) of the Code, licenses of rights to “intellectual property” as defined under Article 101(35A) of the Code. The Parties agree that the Licensing Party shall retain and may fully exercise all of its rights and elections under the Code, and that upon commencement of a bankruptcy proceeding by or against the

Bankrupt Party under the Code, the Licensing Party shall be entitled to a complete duplicate of or complete access to (as the Licensing Party deems appropriate), any such intellectual property and all embodiments of such intellectual property if not already in the Licensing Party’s possession. Such intellectual property and all embodiments thereof shall be promptly delivered to the Licensing Party (a) upon any such commencement of a bankruptcy proceeding upon written request therefor by the Licensing Party, unless the Bankrupt Party elects to continue to perform all of its obligations under this Agreement or (b) if not delivered under (a) above, upon the rejection of this Agreement by or on behalf of the Bankrupt Party upon written request therefore by the Licensing Party.

13.3.2. The Parties further agree that in the event the Bankrupt Party seeks to sell, transfer or otherwise convey the Kadmon IP Rights or Regulatory Approvals, including the ANDA, pursuant to Section 363 of the Code, such sale, transfer or conveyance must be made subject to this Agreement and all licenses and rights to licenses granted under and pursuant to this Agreement, and that no other consideration would suffice to adequately protect the Licensing Party’s rights and interests under this Agreement so as to permit such sale, transfer or conveyance free and clear of the Licensing Party’s rights and interests under Section 363(f) of the Code.

13.3.3. The foregoing provisions of this Section 13.3 are without prejudice to any rights the Licensing Party may have arising under the Code or Applicable Law.

13.4. Survival. Except as otherwise provided herein, in the event of any expiration or termination of this Agreement, (a) all financial obligations hereunder owed as of the effective date of such expiration or termination, including such obligations that have accrued, but have not been invoiced, as of such effective date, shall remain in effect, (b) all rights and obligations that have accrued under this Agreement, including in respect of breaches of the provisions of this Agreement, prior to such expiration or termination, shall survive, and (c) Articles 9, 11 and 14 and Sections 3.7, 8.3, 13.1, 13.2, and, if applicable, 13.3 shall survive. In the event of Kadmon’s material, uncured breach of this Agreement under Section 12.4, notwithstanding any other provision of this Agreement to the contrary, AbbVie may either terminate this Agreement (in which case all of AbbVie’s licenses granted under this Agreement and all royalty obligations under Section 6.3 shall terminate) or continue this Agreement (including AbbVie’s licenses and royalty obligations) and pursue damages.

14. GENERAL PROVISIONS.

14.1. Assignment. Neither Party may assign or transfer its rights or delegate its obligations under this Agreement, in whole or in part, without the prior written consent of the other Party, except that a Party may make such an assignment or delegation without the other Party’s consent to (a) Affiliates, provided that such assignment does not relieve such assigning Party from its obligations hereunder or (b) a successor to substantially all of the business of such Party to which this Agreement pertains, whether in a merger, sale of stock, sale of assets, spin-off or other transaction. Any permitted successor or assignee of rights and/or obligations hereunder shall, in writing to the other Party, expressly assume such rights and/or obligations. Any attempted assignment or

delegation by either Party in violation of the terms of this Section 14.1 shall be null, void and of no legal effect.

Neither Party shall bind, or attempt to bind, the other Party hereto to any contract or the performance of any other obligation, or represent to any Third Party that it is authorized to enter into any contract or binding obligation on behalf of the other Party hereto.

14.6. Dispute Resolution. If a dispute arises between the Parties, the Parties shall follow the alternative dispute resolution provisions provided for in Schedule 14.6.

14.7. Severability. To the fullest extent permitted by Applicable Law, the Parties waive any provision of law that would render any provision in this Agreement invalid, illegal or unenforceable in any respect. If any provision of this Agreement is held to be invalid, illegal or unenforceable, in any respect, then such provision will be given no effect by the Parties and shall not form part of this Agreement. To the fullest extent permitted by Applicable Law and if the rights or obligations of any Party will not be materially and adversely affected, all other provisions of this Agreement shall remain in full force and effect and the Parties will use their best efforts to negotiate a provision in replacement of the provision held invalid, illegal or unenforceable that is consistent with Applicable Law and achieves, as nearly as possible, the original intention of the Parties.

14.8. Interpretation. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” All references herein to Articles, Sections, Exhibits and Schedules shall be deemed references to Articles and Sections of, and Exhibits and Schedules to, this Agreement unless the context shall otherwise require. The subject headings of this Agreement are included for purposes of convenience only, and shall not affect the construction or interpretation of any provision of this Agreement.

14.9. Entire Agreement and Amendments. This Agreement, together with all Schedules attached hereto, and the Ancillary Agreements, constitute the entire agreement between the Parties, and supersedes all prior agreements, understandings and communications between the Parties, with respect to the subject matter hereof and

thereof. No modification or amendment of this Agreement shall be binding upon the Parties unless in writing and executed by the duly authorized representative of each of the Parties.

14.10. Waivers. The failure by either Party hereto to assert any of its rights hereunder, including the right to terminate this Agreement due to a breach or default by the other Party hereto, shall not be deemed to constitute a waiver by that Party of its right thereafter to enforce each and every provision of this Agreement in accordance with its terms.

14.11. Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments and to do all such other acts as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

14.12. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original and all of which taken together shall be deemed to constitute one and the same instrument.
