    11. Representations, Warranties and Disclaimer
    11.1 Each Party represents and warrants to the other Party that it has the full right, power and authority to enter into this Agreement and perform its obligations hereunder.

While the Soapbox System is constantly improving, it will not be error free. Accordingly, except as expressly stated in this Agreement, Soapbox provides the services on an “as is” basis. Except as expressly set forth in this Agreement, Soapbox makes no express or implied warranties regarding the Services, and disclaims all warranties, express or implied, including any implied warranties of merchantability, non-infringement, or fitness for a particular purpose. No warranty is made that use of and access to the Services will be error free or uninterrupted, that any errors or defects in the Services will be corrected, or that the Services will meet the Customer’s requirements.

    12. Confidentiality
    12.1 Each Party shall protect the Confidential Information of the other Party from unauthorised disclosure or dissemination and use no less than that degree of care it uses to protect its own like information, and in any event no less than reasonable care. Neither Party shall use the Confidential Information of the other Party for purposes other than those necessary to directly further the purposes of this Agreement. Neither Party shall disclose the Confidential Information of the other Party, without the prior written consent of the other Party, except: (a) to the Party's employees, officers, agents, professional advisors and counsel who have a legitimate need to know and are subject to obligations of confidentiality at least as restrictive as those contained herein; or (b) to the extent disclosure is required by Applicable Laws. If a Party receives a legal process that demands disclosure of the other Party's Confidential Information, such Party shall give sufficient notice to the other Party to enable it to challenge the demand save where such legal process prohibits such notification. In addition, either Party may provide a copy of this Agreement or otherwise disclose its terms in connection with any audit, financing transaction, regulatory or due diligence inquiry provided the recipients are subject to obligations of confidentiality at least as restrictive as those contained herein. Except as expressly provided in this Agreement, no ownership or license rights are granted in any Confidential Information.

    13. Data Protection
    13.1 The Soapbox System applies a “data protection by default” and “data protection by design” approach in keeping with the principle of minimizing the processing of personal data to the extent necessary to provide the Services and to further develop and enhance the Soapbox System. Accordingly, Soapbox will not take any steps to re-identify or de-anonymize any End User Voice Data or otherwise associate the End User Voice Data with personally identifiable information and shall not authorize, instruct or encourage any third party to do so.
    13.2 For its part the Customer shall comply with all Applicable Laws governing the collection, use, handling, disclosure, or retention of data collected from or about End Users or any specific devices.
    13.3 If and to the extent that Soapbox is acting as a “data processor” under Applicable Laws during the Term, Soapbox will comply with the obligations prescribed by Article 28 of the EU General Data Protection Regulation (2016/679) while performing the Services for the Customer during the Term. If and to the extent that the retention and use of the End User Voice Data by Soapbox (as permitted by Clauses 2.2 and 3.1(c)(ii) of this Agreement) is such as to constitute processing by a “data controller” under Applicable Laws, Soapbox relies on the Customer to ensure that all necessary notices, consents and other measures are in place as required by Clause 3.1 to permit such processing.

    14. Not Used

    15. Exclusions and Liability Limitations
    15.1 To the maximum extent permitted by Applicable Laws, and except for (a) the indemnification obligations in this Agreement, or (b) breaches of confidentiality, in no event shall either Party, its licensors or its suppliers be liable for any lost profits or any special, indirect, incidental, punitive or consequential damages of any kind or nature whatsoever, relating to this Agreement or the transactions contemplated hereby, including without limitation, lost profits or lost goodwill, regardless of whether such Party has been advised of the possibility of such damage or if such damage could have been reasonably foreseen.
    15.2 Subject to Clause 15.3, in no event whatsoever shall Soapbox be liable to the Customer for an amount exceeding €10,000.
    15.3 Nothing in this Agreement limits or excludes liability of either Party in respect of: (a) any claims for death or personal injury caused by the negligence of such Party; (b) any claims resulting from any fraud including fraudulent misrepresentation made by such Party; or (c) any claims for which liability may not otherwise lawfully be limited or excluded.
    15.4 The disclaimers, exclusions and limitations of liability set forth in this Clause 15 apply regardless of whether the liability is based on breach of contract, tort (including negligence), strict liability, breach of warranties, or any other legal theory, and notwithstanding the failure of the essential purpose of any remedy. The Parties agree that the disclaimers, exclusions and limitations of liability set forth in this Clause 15 reflect a reasonable allocation of risk, and that each Party would not have entered into this Agreement without them.

    16. Indemnification
    16.1 The Customer shall defend and indemnify Soapbox and its officers, directors, employees, successors and assigns (collectively the “Soapbox Indemnified Parties”), from and against all third party claims, suits, demands and actions brought against the Soapbox Indemnified Parties or tendered to the Soapbox Indemnified Parties for defence and/or indemnification (each a “Soapbox Claim”), and for resulting damages, losses, costs, expenses and liabilities (including any regulatory fines and reasonable legal and professionals' fees) that result or arise from a breach by the Customer of Clause 11.2.
    16.2 In respect of any Soapbox Claim:
    a. Soapbox shall promptly notify the Customer in writing of the Soapbox Claim, provided that any delay in notification will not relieve the Customer of its obligations with respect to the claim except to the extent that the delay prejudices its ability to defend the Soapbox Claim;
    b. Soapbox shall allow the Customer to have sole control over the defence and/or settlement of the Soapbox Claim, so long as the Customer does not enter into a settlement that requires Soapbox to make an admission of fault or payment to any third party; and
    c. Soapbox shall provide the Customer with reasonable assistance in the defence and settlement of the Soapbox Claim at the Customer’s sole cost and expense; provided, however, that Soapbox may participate in the defence and settlement of the Soapbox Claim beyond what is requested at its own cost with legal advisers of its own choosing.

    17. General
    17.1 Nothing in this Agreement should be construed as creating an agency, partnership, joint venture, franchise, or employment relationship between the parties. Neither Party has the authority to make any statements, representations or commitments of any kind, or to take any action binding on the other, except to the extent (if any) provided for in this Agreement. For the avoidance of doubt, Soapbox consents to the disclosure of its role in providing the Services where this is necessary for the Customer to meet its notice, consent or other requirements under Applicable Laws.
    17.2 This Agreement, the jurisdiction clause contained in it, all the documents referred to in it which are not expressed to be governed by another law, and all non-contractual obligations arising in any way whatsoever out of or in connection with this Agreement or any such document are governed by, and shall be construed and take effect in accordance with the laws of Ireland. The courts of Ireland have exclusive jurisdiction to settle any claim, dispute or matter of difference which may arise in any way whatsoever out of or in connection with this Agreement (including without limitation claims for set off or counterclaim) or the legal relationships established by this Agreement.
    17.3 The Parties shall comply with all applicable international and national laws that apply to the End User Voice Data, including the U.S. Export Administration Regulations, as well as end user, end use and destinations restrictions issued by U.S. or other governments.
    17.4 Neither Party will assign any rights under this Agreement (including by operation of law or otherwise) without the prior written consent of the other Party, which consent shall not be unreasonably withheld. Despite the preceding sentence, with the exception of an assignment to a competitor of the non-assigning Party (which shall require consent from the non-assigning Party), this Agreement may be assigned in its entirety by either Party, without obtaining the consent of the other Party, to an entity into which the assigning Party is merged, or to an acquirer of all or substantially all of the business or assets of the business unit of the assigning Party to which this Agreement pertains, or as part of a business restructuring, sale of stock, or other recapitalization or reorganization. Any purported assignment of rights or transfer of obligations in violation of this paragraph is void.
    17.5 If for any reason a court of competent jurisdiction finds any provision of this Agreement, or portion thereof, to be unenforceable, that provision of the Agreement will be enforced to the maximum extent permissible so as to effect the intent of the Parties, and the remainder of this Agreement will continue in full force and effect. No waiver of any breach of any provision of this Agreement shall constitute a waiver of any prior, concurrent or subsequent breach of the same or any other provisions hereof, and no waiver shall be effective unless made in writing and signed by an authorized representative of the waiving Party. The Parties and their respective legal advisers have had an opportunity to review this Agreement which will be interpreted fairly in accordance with its terms and without any strict construction in favor of or against either Party, including by reason of a Party’s drafting or preparing the Agreement.
    17.6 Neither Party will be liable for any delay, interruption in service or failure to perform its obligations hereunder, other than a payment obligation, due to any Force Majeure event provided that the affected Party provides the other Party with prompt notice of the applicable circumstance and uses commercially reasonable efforts to re-commence performance as promptly as possible; provided, further, that if the duration of such event of Force Majeure exceeds thirty (30) days, the other Party may terminate this Agreement upon delivery of written notice to the affected Party.
    17.7 Unless otherwise expressly provided, no provision of this Agreement is intended or shall be construed to confer upon or give to any person or entity other than Soapbox and the Customer any rights, remedies or other benefits under or by reason of this Agreement.
    17.8 This Agreement constitutes the entire agreement between the Parties with respect to the subject matter hereof and merges all prior and contemporaneous communications.
    17.9 This Agreement shall not be modified or amended except by a written agreement dated subsequent to the date of this Agreement and signed on behalf of Soapbox and the Customer by their respective duly authorized representatives.
