For the avoidance of doubt, Licensee is not obligated to pay any interest for the period during which the Parties were in dispute of the account firm’s conclusion and amount owed thereunder.

SECTION 9.2. Licensee Indemnification. Licensee shall defend the Licensor Indemnified Parties from and against Claims that are brought by a Third Party, and shall indemnify and hold harmless to the fullest extent permitted by law the Licensor Indemnified Parties from and against any and all Losses, that arise out of or are attributable to (i) Licensee’s gross negligence or willful misconduct in exercising or performing any of its rights or obligations under this License Agreement; or (ii) a material breach by Licensee of any of its obligations, representations, warranties or covenants under this License Agreement; provided, however, that Licensee shall not be obligated to indemnify Licensor under this SECTION 9.2, to the extent such Claim arose out of the gross negligence or willful misconduct of Licensor or to the extent such Claim is covered by Licensor’s indemnity below.

SECTION 9.3. Licensor Indemnification. Licensor shall defend the Licensee Indemnified Parties from and against all Claims, in each case that are brought by a Third Party, and shall indemnify and hold harmless to the fullest extent permitted by law the Licensee Indemnified Parties from and against any and all Losses that arise out of such Claims that are attributable to (i) the use of the Intellectual Property in the Compound or Licensed Products as authorized by this License Agreement infringing, misappropriating or violating the Intellectual Property of such Third Party, (ii) Licensor’s gross negligence or willful misconduct in exercising or performing any of its rights or obligations under this License Agreement; or (iii) a material breach by Licensor of any of its obligations, representations, warranties or covenants under this License Agreement; provided, however, that Licensor shall not be obligated to indemnify Licensee under this SECTION 9.3, to the extent such Claim arose out of the gross negligence or willful misconduct of Licensee.

SECTION 9.4. Indemnification Procedure.

(a)    Each Party shall promptly notify the other Party in writing of any Claim. Concurrent with the provision of notice pursuant to this SECTION 9.4(a), the indemnified Party shall provide to the other Party copies of any complaint, summons, subpoena or other court filings or correspondence related to such Claim and will give such other information with respect thereto as the other Party shall reasonably request. The indemnifying Party and indemnified Party shall meet to discuss how to respond to such Claim. Failure to provide prompt notice shall not relieve any Party of the duty to defend or indemnify unless such failure materially prejudices the defense of any matter. Each Party agrees that it will take reasonable steps to minimize the burdens of the litigation on witnesses and on the ongoing business of the indemnified Parties including by making reasonable accommodations to witnesses’ schedules when possible and seeking appropriate protective orders limiting the duration and/or location of depositions.

(b)    Should either Party dispute that any Claim or portion of a Claim (“Disputed Claim”) of which it receives notice pursuant to SECTION 9.4(a), is an indemnified Claim, it shall so notify the other Party providing written notice in sufficient time to permit such other Party to retain counsel and timely appear, answer and/or move in any such action. In such event, such other Party shall defend against such Claim; provided, however, that such other Party shall not settle any Claim which it contends is an indemnified Claim without providing the indemnifying Party 10 Business Days’ notice prior to any such settlement and an opportunity to assume the defense and indemnification of such Claim pursuant to this License Agreement. If it is determined that a Disputed Claim is subject to indemnification, the indemnifying Party will reimburse the costs and expenses, including reasonable attorneys’ fees, of the indemnified Party.

SECTION 9.5. Settlement of Indemnified Claims. The indemnifying Party under SECTION 9.2 or SECTION 9.3, as applicable, shall have the sole authority to settle any indemnified Claim without the consent of the other Party, provided, however, that an indemnifying Party shall not,

without the written consent of the other Party, as part of any settlement or compromise (i) admit to liability on the part of the other Party; (ii) agree to an injunction against the other Party; (iii) separately apportion fault to the other Party in any manner or (iv) agree to a settlement or compromise that would result in any loss of rights or material liability to the other Party. The Parties further agree that as part of the settlement of any indemnified Claim, an indemnifying Party shall obtain a full, complete and unconditional release from the claimant on behalf of the indemnified Parties.

SECTION 9.6. Limitation of Liability. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER OR ANY OF ITS AFFILIATES FOR ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES (INCLUDING LOST PROFITS, BUSINESS OR GOODWILL) SUFFERED OR INCURRED BY SUCH OTHER PARTY OR ITS AFFILIATES, WHETHER BASED UPON A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR OTHER TORT, OR OTHERWISE, ARISING OUT OF THIS LICENSE AGREEMENT.
