Kadmon shall use its Commercially Reasonable Efforts, at Kadmon’s sole cost and expense, to obtain the consent of the other parties to any such Non-Assignable Contract for the assignment thereof to AbbVie. Unless and until such consent is obtained, or if an attempted assignment thereof would be ineffective or would materially adversely affect the rights of Kadmon thereunder so that AbbVie would not in fact receive all rights under such Non-Assignable Contract, then, notwithstanding anything to the contrary in this Agreement, (a) this Agreement and the related instruments of transfer shall not constitute an assignment or transfer of the Non-Assignable Contract, and (i) Kadmon shall use its Commercially Reasonable Efforts to obtain such consent as soon as possible after the Closing Date and (ii) AbbVie shall cooperate, to the extent commercially reasonable, with Kadmon in its efforts to obtain such consent; and (b) at AbbVie’s election prior to Closing, (i) the Non-Assignable Contract shall not constitute a Purchased Asset and AbbVie shall have no obligation with respect to any such Non-Assignable Contract or any liability with respect thereto or (ii) Kadmon shall use its Commercially Reasonable Efforts to obtain for AbbVie substantially all of the practical benefit of such Non-Assignable Contract, including by (A) entering into appropriate and reasonable alternative arrangements on terms mutually and reasonably agreeable to Kadmon and AbbVie and (B) subject to the consent and control of AbbVie, enforcement of any and all rights of Kadmon against the Third Party thereto arising out of the breach or cancellation thereof by such Third Party or otherwise.

AbbVie’s rights to make claims for breaches of or inaccuracies in such representations or warranties pursuant to Section 6 of this Agreement.

Kadmon shall prepare and timely file all Tax Returns due on or before the Closing Date with respect to the Purchased Assets, and AbbVie shall prepare and timely file all Tax Returns due after the Closing Date with respect to the Purchased Assets, including such Tax Returns for a Straddle Period.

If one Party remits to the appropriate Taxing Authority payment for Taxes and such payment includes the other Party’s share of such Taxes, to the extent not paid at or before the Closing, such other Party shall promptly reimburse the remitting Party for its share of such Taxes after the remitting Party has provided reasonable written evidence to the other Party that such Taxes have been timely paid.

3.3.4 Cooperation.

3.6 Application for Assignment of Health Registrations. In accordance with Applicable Laws, AbbVie shall prepare and file, and Kadmon shall provide AbbVie with all assistance required in preparing and filing all documents necessary to Transfer the Registrations to an AbbVie Party or their designee in each country in the Territory in which Kadmon currently holds a Registration. To the extent that Kadmon is required to file documents with a Governmental Authority as the holder of a Registration to effectuate the Transfer of such Registration in accordance with Applicable Laws, Kadmon shall file all necessary documents with the applicable Governmental Authority as promptly as practical following request by AbbVie. Prior to Kadmon’s filing any such documents with the appropriate Governmental Authority, AbbVie shall have the right to review and approve any such documents.

3.7 Expenses Associated with Transfer. Kadmon shall, at its own cost and expense, undertake and cause its Affiliates to undertake all reasonable and necessary steps to maintain such Registrations in full force and effect up to the Transfer Date or such other date as the Parties may subsequently agree, including each step set forth on Schedule 3.7. Except as explicitly set forth in this Agreement, each of the Parties shall bear its own costs and expenses in connection with any such Transfer of the Registrations in the Territory to AbbVie or its Affiliates (or, if applicable, the issuance of new Registrations with respect to the Products in the Territory in the name of AbbVie or its Affiliates); provided, however, that AbbVie shall be responsible for the payment of any filing or similar fees payable to the applicable Governmental Authority in the Territory with respect to the Transfer of (or issuance of new) Registrations with respect to the

Product in the Territory and with respect to the transfer of the Regulatory Approvals for which AbbVie is responsible under Section 2.3. Transfer of title to each of the Registrations will take place on the respective Transfer Date for each Product for each country.

Kadmon agrees that if, during the No Shop Period, it or its Affiliates and their respective Representatives receives any proposal for any Third Party Transaction or any request for nonpublic information in connection with such a proposal, or for access to Kadmon’s books or records, or its properties by any Third Party that has made such a proposal, Kadmon shall promptly advise AbbVie in writing of the receipt, directly or indirectly, of any inquiry, proposal or other materials, and of any discussions, negotiations or proposals relating to, any Third Party Transaction and the general terms thereof.

The Parties intend that this non-competition provision shall be deemed to be a series of separate covenants, one for each and every country in the Territory.

3.10.3 AbbVie Undertaking.

The Parties agree that transfer of title and ownership with respect to such Intellectual Property Rights will take place immediately following receipt of the Registration in any country in the Territory for the QD Formulation and no payment shall be made by AbbVie pursuant to Section 2.3.1(i) until (a) such transfer has been completed in form and substance reasonably acceptable to AbbVie, (b) Kadmon shall have transferred to AbbVie all Manufacturing Documentation owned by Kadmon and generated from and after the Effective Date that is necessary or useful for AbbVie to manufacture the QD Formulation in the applicable country in the Territory, which Manufacturing Documentation shall be jointly owned by the parties in accordance with Section 2.1, and (c) to the extent any Third Party owns or controls any Manufacturing Documentation generated from and after the Effective Date that is necessary or useful for AbbVie to manufacture the QD Formulation in the applicable country in the Territory, Kadmon shall have provided copies of any such Manufacturing Documentation to AbbVie.

6.5.1 Procedure. Promptly after the discovery by the Party seeking indemnification under Section 6.2 or 6.3 herein (the “Indemnified Party”) of any Loss, claim or breach, including any claim by a Third Party (a “Third Party Claim”) that would reasonably be expected to give rise to a claim for indemnification hereunder, the Indemnified Party shall give written notice to the Party against whom indemnity is sought (the “Indemnifying Party”); provided that, no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder, except to the extent that the Indemnifying Party has been prejudiced thereby, and then only to such extent. The Indemnifying Party, upon request of the Indemnified Party, shall assume the defense of the Third Party Claim and retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnifying Party and the Indemnifying Party shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (a) the Parties shall have mutually agreed to the retention of such counsel, (b) the named parties to any such proceeding (including any impleaded parties) include the Parties and representation of both Parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (c) the Indemnified Party assumes the defense of a Third Party Claim after the Indemnifying Party has failed to diligently defend a Third Party Claim it has assumed per the Indemnified Party’s request. All such fees and expenses incurred pursuant to this Section 6.5 shall be reimbursed as they are incurred. In the event that the Indemnified Party assumes the defense of any Third Party Claim, the Indemnified Party’s right to indemnification for a Third Party Claim shall not be adversely affected by assuming the defense of such Third Party Claim. The Indemnifying Party shall not be liable for any settlement of any proceeding unless affected with its written consent (which shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party shall not, without the written consent of the Indemnified Party (which shall not be unreasonably withheld, conditioned or delayed), effect any settlement of any Third Party Claim unless (a) such settlement includes an unconditional release of the Indemnified Party from all liability on claims to which the indemnity relates that are the subject matter of such proceeding and (b) it would not result in (i) the imposition of a consent order, injunction or decree that would restrict the future activity or conduct of the Indemnified Party or any of its Affiliates with respect to the Compound, Product, or any of the Purchased Assets, (ii) a finding or admission of a violation of Applicable Law or violation of the rights of any Person by the Indemnified Party or any of its Affiliates or (iii) any monetary liability of the Indemnified Party arising from such Third Party Claim that shall not be promptly paid or reimbursed by the Indemnifying Party.

6.5.2 Confidential Information. The Indemnified Party and the Indemnifying Party shall use Commercially Reasonable Efforts to avoid production of Confidential Information (consistent with Applicable Law), and to cause all communications among employees, counsel and others representing any party to a Third Party Claim to be made so as to preserve any applicable attorney-client or work-product privileges.

6.6 Direct Claims. If an Indemnified Party wishes to make a claim for indemnification hereunder for a Loss that does not result from a Third Party Claim (a “Direct Claim”), the Indemnified Party shall notify the Indemnifying Party in writing of such Direct Claim promptly after first learning of such Direct Claim, the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Direct Claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto. The Indemnifying Party shall have a period of *** business days within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such *** business day period or rejects all or any part of the Direct Claim, the Indemnified Person shall be free to seek enforcement of its rights to indemnification under this Agreement and the Escrow Agreement with respect to such Direct Claim.

6.7 Treatment of Indemnity Payments. Any payment made pursuant to this Section 6 shall be treated as an adjustment to the Purchase Price to the extent permitted by Applicable Law.

6.8 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 Exhibit G, 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

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 be provided advance copies of any documents related thereto for review and comment; provided, however, that the final decision with respect thereto shall rest with Kadmon.

(a) Each Party shall promptly report in writing to the other Party during the Term any known or suspected infringement of the Patent Application (“Infringement”). The reporting Party shall provide the other Party with all 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.

(b) Kadmon shall have the first right to initiate a suit or take other appropriate action that it believes is reasonably required to protect the Patent Application in the United States against any Infringement. If Kadmon decides not to initiate a suit or take other appropriate action with respect to any such Infringement in the United States, then 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 United States, and shall agree to be parties in any suit, if requested.

(c) Without regard to which Party initiates a suit or takes other appropriate action with respect to any Infringement in the Territory under Section 8.15.3(b), all costs (including all reasonable costs and expenses associated with any defense of a claim hereunder) associated with any such action in the United States, 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.

(d) The enforcing Party under Section 8.15.3(b) 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.
