Section 6.5 — Taxes.
Each Party shall be responsible for its own tax obligations arising in connection with this Agreement, including but not limited to income taxes, employment taxes, and any applicable state or local taxes. Institution represents and warrants that it is a tax-exempt entity under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended, and shall provide Sponsor with a copy of its tax-exemption determination letter upon request. Neither Party shall be responsible for any tax obligations of the other Party.
Section 6.6 — No Additional Compensation.
The compensation set forth in this Article 6 constitutes the entire financial obligation of Sponsor to Institution for the conduct of the Study. No additional fees, overhead charges, indirect cost recovery, administrative surcharges, or other costs shall be payable by Sponsor except as expressly set forth in this Agreement or in a written amendment hereto executed by both Parties. Institution acknowledges that the payments set forth herein reflect fair market value for the services to be provided and have been determined through arm's-length negotiation between the Parties.
Section 6.7 — Financial Records and Audit Rights.
Institution shall maintain accurate, complete, and contemporaneous financial records of all Study-related expenditures, revenues, and allocations for a period of three (3) years following the completion of the Study or the termination of this Agreement, whichever is later. Sponsor, or its designated independent auditors (currently Whitman, Sadler & Co. LLP), shall have the right to audit such financial records upon not less than thirty (30) days' prior written notice to Institution. Such audits shall be conducted during normal business hours at Institution's facilities and shall be limited in scope to verification of the accuracy of invoices submitted to Sponsor and the proper use of Study funds. Institution shall cooperate fully with any such audit and shall provide reasonable access to its financial records, accounting systems, and relevant personnel. If an audit reveals an overpayment by Sponsor, Institution shall refund the overpayment to Sponsor within thirty (30) days of written notification. If an audit reveals an underpayment, Sponsor shall remit the balance due within thirty (30) days.
ARTICLE 7 — INDEMNIFICATION
Section 7.1 — Sponsor Indemnification of Institution.
Sponsor shall defend, indemnify, and hold harmless Institution, the Principal Investigator, the Sub-Investigator, Study Staff, and their respective officers, directors, trustees, employees, agents, successors, and assigns (collectively, the "Institution Indemnitees") from and against any and all claims, demands, actions, causes of action, suits, proceedings, judgments, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees, expert witness fees, and court costs) (collectively, "Losses") asserted by any third party and arising out of or relating to:
(a) the design, manufacture, supply, labeling, packaging, transportation, or any inherent defect, malfunction, or failure of the ThornValve MV-200 System (Investigational Device), including but not limited to any product liability claim, strict liability claim, breach of warranty claim, or claim based on the design or manufacturing specifications of the Device;
(b) any other claim arising out of or relating to the Investigational Device or its use in the Study, to the extent such claim is not caused by or attributable to Institution's negligence, material deviation from the Protocol that was not approved in writing by Sponsor, failure to obtain Informed Consent, or willful misconduct; and
(c) the negligence or willful misconduct of Sponsor, its officers, directors, employees, agents, or contractors in connection with the Study or any activities performed under this Agreement.
Section 7.2 — Conditions to Sponsor Indemnification.
Sponsor's indemnification obligations under Section 7.1 are subject to the following conditions:
(a) Institution shall provide Sponsor with prompt written notice of any claim, demand, action, or threatened action for which indemnification is sought, and in no event later than twenty (20) business days after Institution first becomes aware of such claim, demand, action, or threatened action. Failure to provide timely notice shall not relieve Sponsor of its indemnification obligations except to the extent Sponsor is materially prejudiced by such failure.
(b) Sponsor shall have the right, but not the obligation, to assume and control the defense and settlement of any claim for which it provides indemnification under this Article 7, using legal counsel of Sponsor's selection. If Sponsor assumes the defense, Sponsor shall diligently prosecute such defense and shall keep Institution reasonably informed of the progress of such defense.
(c) Institution may participate in the defense of any claim for which Sponsor has assumed the defense, with separate legal counsel of Institution's own choosing and at Institution's own expense; provided, however, that if a bona fide conflict of interest exists between the interests of Sponsor and Institution in the defense of such claim such that joint representation would be inappropriate, Institution's reasonable costs and expenses of separate counsel shall be borne by Sponsor. Any determination of whether a bona fide conflict of interest exists shall be made in good faith by the Parties.
(d) No settlement of any claim that imposes any obligation, admission of liability, injunctive relief, or restriction on any Institution Indemnitee shall be entered into without Institution's prior written consent, which consent shall not be unreasonably withheld, conditioned, or delayed.
Section 7.3 — Exclusions from Sponsor Indemnification.
Notwithstanding Section 7.1, Sponsor's indemnification obligations under this Article 7 shall not extend to any Losses to the extent arising from or attributable to:
(a) the negligence or willful misconduct of Institution, the PI, the Sub-Investigator, or any member of Study Staff in the conduct of the Study;
(b) any material deviation from the Protocol by Institution, the PI, or Study Staff that was not approved in writing by Sponsor prior to or promptly following such deviation;
(c) the failure of Institution, the PI, or any member of Study Staff to obtain proper Informed Consent from a Study Subject in accordance with the requirements of this Agreement, the Protocol, 21 C.F.R. Part 50, and applicable law; or
(d) any material breach of this Agreement by Institution.
In the event a claim involves both matters for which Sponsor is obligated to indemnify under Section 7.1 and matters excluded under this Section 7.3, the Parties shall allocate responsibility for such claim in proportion to their respective fault, as determined by agreement of the Parties or, if the Parties are unable to agree, by a court of competent jurisdiction.
Section 7.4 — Aggregate Cap on Sponsor Indemnification.
Sponsor's aggregate liability for all indemnification obligations under this Article 7 shall not exceed Fifteen Million Dollars ($15,000,000.00) (the "Indemnification Cap"). This Indemnification Cap represents the total maximum aggregate amount payable by Sponsor under Sections 7.1 and 7.2 for all claims combined during the term of this Agreement and any post-termination survival period. The Indemnification Cap has been established by the Parties through arm's-length negotiation and is supported by Sponsor's clinical trial liability insurance aggregate coverage of Twenty-Five Million Dollars ($25,000,000.00) under Commonwealth Specialty Underwriters Policy No. CTL-2025-08843.
Section 7.5 — Institution Indemnification of Sponsor.
Institution shall defend, indemnify, and hold harmless Sponsor and its officers, directors, trustees, employees, agents, successors, and assigns (collectively, the "Sponsor Indemnitees") from and against any and all Losses asserted by any third party and arising out of or relating to:
(a) the gross negligence or willful misconduct of Institution, the PI, the Sub-Investigator, or any member of Study Staff in connection with the conduct of the Study or any activities performed under this Agreement; and
(b) a material breach of this Agreement by Institution.
Section 7.6 — Conditions to Institution Indemnification.
Institution's indemnification obligations under Section 7.5 are subject to the following conditions, which are analogous to those set forth in Section 7.2:
(a) Sponsor shall provide Institution with prompt written notice of any claim, demand, action, or threatened action for which indemnification is sought under Section 7.5, and in no event later than twenty (20) business days after Sponsor first becomes aware of such claim, demand, action, or threatened action. Failure to provide timely notice shall not relieve Institution of its indemnification obligations except to the extent Institution is materially prejudiced by such failure.
(b) Institution shall have the right, but not the obligation, to assume and control the defense and settlement of any claim for which it provides indemnification under Section 7.5, using legal counsel of Institution's selection.
(c) Sponsor may participate in the defense of any claim with separate counsel at its own expense, subject to the same conflict-of-interest provisions set forth in Section 7.2(c), mutatis mutandis.
(d) No settlement of any claim that imposes any obligation, admission of liability, injunctive relief, or restriction on any Sponsor Indemnitee shall be entered into without Sponsor's prior written consent, which consent shall not be unreasonably withheld, conditioned, or delayed.
Section 7.7 — Limitation.
NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE STUDY, REGARDLESS OF THE FORM OF ACTION OR THEORY OF LIABILITY, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR OTHERWISE, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
