Enforcement and Defense. In the event that Northern or Spero becomes aware of a suspected infringement of any Northern Patent Right, or any such Northern Patent Right is challenged in any action or proceeding (other than any interferences, oppositions, reissue proceedings or reexaminations, which are addressed above), such Party shall notify the other Party promptly, and following such notification, the Parties shall confer. Except as otherwise provided below, Spero shall have the right, but shall not be obligated, to defend any such action or proceeding or bring an infringement action with respect to such infringement at its own expense, in its own name and entirely under its own direction and control, or settle any such action or proceeding by sublicense; provided that, if there exists an issued SC Patent to serve as the basis of the infringement action in connection with such Third Party activities, Spero will limit its enforcement action to such SC Patent if so doing does not materially decrease Spero’s likelihood of success. Prior to initiating an enforcement action that uses a Northern Patent Right other than an SC Patent as the basis for the claim of infringement, Spero shall meet with Northern to discuss ways to manage the potential risk to such Northern Patent Right in connection with such enforcement action, including limiting the number and scope of claims that are asserted in connection with such action. Spero shall use good faith efforts to employ any reasonable measures agreed to by the Parties to manage such potential risk. Northern shall reasonably assist Spero in any action or proceeding being defended or prosecuted if so requested, and shall join such action or proceeding if reasonably requested by Spero or required by applicable law at Spero’s expense. After Spero has recovered an amount equal to the cost it incurred in connection with any such action or proceeding, any remaining and received amounts of compensation and/or damages paid by a third party as awarded to Spero due to the above action or proceeding shall be shared ​ percent (​) to Spero and ​ percent (​) to Northern. With respect to infringements arising out of the activities of a Third Party with a compound that is an Other Compound, Northern shall have the right, but shall not be obligated, to defend any such action or proceeding or bring an infringement action with respect to such

Assumption of Defense. In the event the Company shall be requested by Indemnitee to pay the Expenses of any proceeding, the Company, if appropriate, shall be entitled to assume the defense of such proceeding, or to participate to the extent permissible in such proceeding, with counsel reasonably acceptable to Indemnitee. Upon assumption of the defense by the Company and the retention of such counsel by the Company, the Company shall not be liable to Indemnitee under this Agreement for any fees of counsel subsequently incurred by Indemnitee with respect to the same proceeding, provided that Indemnitee shall have the right to employ separate counsel in such proceeding at Indemnitee’s sole cost and expense. Notwithstanding the foregoing, if Indemnitee’s counsel delivers a written notice to the Company stating that such counsel has reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense or the Company shall not, in fact, have employed counsel or otherwise actively pursued the defense of such proceeding within a reasonable time, then in any such event the fees and Expenses of Indemnitee’s counsel to defend such proceeding shall be subject to the indemnification and advancement of Expenses provisions of this Agreement.

Defense of Claim. The indemnifying party shall defend or control the defense of Third Party Claims. The indemnifying party shall be responsible for satisfying and discharging any award made to or settlement reached with the Third Party pursuant to the terms of this Agreement. The indemnifying party shall retain counsel reasonably acceptable to the indemnified party (such acceptance not to be unreasonably withheld, refused, conditioned or delayed) to represent the indemnified party and shall pay the reasonable fees and expenses of such counsel related to such proceeding. In any such proceeding, the indemnified party, at its sole expense, shall have the right to retain its own counsel. The indemnified party shall cooperate in all reasonable respects in the defense of such Third Party Claim, as requested by, and at the reasonable expense of, the indemnifying party. The indemnifying party shall not, without the written consent of the indemnified party (which consent shall not be unreasonably withheld, refused, conditioned or delayed), effect any settlement of any such Third Party Claim, unless such settlement includes a full and unconditional release of the indemnified party from all liability on such Claims.

Control of Defense. In the event Assignor seeks indemnification under Section 9.1, Assignor shall inform Assignee of a claim as soon as reasonably practicable after Assignor receives notice of the claim (it being understood and agreed, however, that the failure by Assignor to give notice of a claim as provided in this Section 9.2 shall not relieve Assignee of Assignee’s indemnification obligation under this Agreement except and only to the extent that Assignee is actually damaged as a direct result of such failure to give notice), shall permit Assignee to assume direction and control of the defense of the claim (including the right to settle the claim solely for monetary consideration) using counsel reasonably satisfactory to Assignor, and shall cooperate as requested (at the expense of Assignee) in the defense of the claim. If Assignee does not assume control of such defense within […​…] after receiving notice of the claim from Assignor, Assignor shall control such defense and, without limiting Assignee’s indemnification obligations, Assignee shall reimburse Assignor for all costs, including reasonable attorney fees, incurred by Assignor in defending itself within […​…] after receipt of any invoice therefor from Assignor. The party not controlling such defense may participate therein at such party’s own expense. 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. Assignor shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of Assignee, which shall not be unreasonably withheld, delayed or conditioned. Assignee shall not agree to any settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of Assignor from all liability with respect thereto, that imposes any liability or obligation on Assignor, that acknowledges fault by Assignor without the prior written consent of Assignor.

Control of Defense. Except with respect to any Third Party Claim that is a Third Party Infringement Claim, the process for the defense of which shall be governed by Section 7.5, at its option, the Indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within thirty (30) days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the Indemnifying Party shall not be construed as an acknowledgment that the Indemnifying Party is liable to indemnify any Allergan Indemnitee or UroGen Indemnitee, as applicable, in respect of such Third Party Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against an Allergan Indemnitee’s or UroGen Indemnitee’s, as applicable, claim for indemnification. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the Indemnifying Party. If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the Indemnifying Party all original notices and documents (including court papers) received by any Allergan Indemnitee or UroGen Indemnitee, as applicable, in connection with the Third Party Claim. If the Indemnifying Party assumes the defense of a Third Party Claim, except as provided in [Section 10.2.3], the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party or any Allergan Indemnitee or UroGen Indemnitee, as applicable, in connection with the analysis, defense or settlement of such Third Party Claim. If it is ultimately determined that the Indemnifying Party is not obligated to indemnify, defend or hold harmless an Allergan Indemnitee or UroGen Indemnitee, as applicable, from and against a Third Party Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all costs and expenses (including attorneys’ fees and costs of suit) and any Losses incurred by the Indemnifying Party in its defense of such Third Party Claim.

Defense by Company. Subject to the provisions of the last sentence of this [Section 11(b)] and of [Section 11(c)] below, the Company shall have the right to defend Indemnitee in any Proceeding which may give rise to the payment of Indemnifiable Amounts hereunder; provided, however that the Company shall notify Indemnitee of any such decision to defend within ten (10) calendar days of receipt of notice of any such Proceeding under [Section 11(a)] above. The Company shall not, without the prior written consent of Indemnitee, consent to the entry of any judgment against Indemnitee or enter into any settlement or compromise which # includes an admission of fault of Indemnitee or # does not include, as an unconditional term thereof, the full release of Indemnitee from all liability in respect of such Proceeding, which release shall be in form and substance reasonably satisfactory to Indemnitee. This [Section 11(b)] shall not apply to a Proceeding brought by Indemnitee under [Section 10(a)] above or pursuant to [Section 19] below.

Defense to Future Claims. Executive agrees that in the event that any claim, suit or action shall be commenced by her against the Company arising out of any charge, claim or cause of action of any nature whatsoever, known or unknown, including, but not limited to, claims, suits or actions relating to her employment with Patterson or any prior agreement with Patterson, through this date, this Agreement shall constitute a complete defense to any such claims, suits or actions so instituted.

Failure to Act Not a Defense. The failure of the Company (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of the payment of Indemnifiable Amounts or the advancement of Indemnifiable Expenses under this Agreement shall not be a defense in any action brought under [Section 10(a)] above, and shall not create a presumption that such payment or advancement is not permissible.

Defense to Indemnification and Burden of Proof. It shall be a defense to any action brought by the Indemnitee against the Company to enforce this Agreement (other than an action brought to enforce a claim for Losses incurred in defending against a Claim related to an Indemnifiable Event in advance of its final disposition) that it is not permissible under applicable law for the Company to indemnify the Indemnitee for the amount claimed. In connection with any such action or any related Standard of Conduct Determination, the burden of proving such a defense or that the the Indemnitee did not satisfy the applicable standard of conduct shall be on the Company.

Defense of Third-Party Intellectual Property Claims. Each Party shall promptly notify the other Party upon becoming aware of any actual or threatened claim that the Commercialization of any Product infringes or misappropriates the Intellectual Property Rights of a Third Party (each, a “Third Party IP Claim”). Each Party may defend itself from any such Third Party IP Claim brought against such Party or its Affiliates or licensees (or in the case of Commercializing Party, sublicensees) at its own expense and with counsel of its choosing. Each Party shall keep the other Party reasonably informed of all material developments in connection with any Third Party IP Claim, and the other Party shall consult with and offer reasonable assistance to the Party defending against such Third Party IP Claim, at the defending Party’s cost and expense.
