11.3 The indemnification obligation set forth in clause 11 (1) and (2) shall not apply, and Licensor shall in no event be liable, if the alleged infringement is due to (i) a modification of the Software by anyone other than the Licensor or/and an unauthorised use of the Software; (ii) Licensee’s marketing, advertising, distribution or use of the Software in a manner contrary to the instructions of Licensor and contrary to the terms of the Agreement; (iii) Licensee’s marketing, advertising, distribution or use of the Software after notice of the alleged or actual infringement from Licensor; (iv) Licensee’s negligent or grossly negligent acts or omissions; (v) Licensee’s bad faith failure to comply with the Agreement.

The termination shall not affect the Parties’ rights under the Agreement that accrued prior to termination.

14. Miscellaneous

14.1 Severability Clause
Should one or several provisions of the Agreement be or become invalid, the validity of the rest of the Agreement shall not be affected, and the Parties shall replace the invalid provision(s) with valid ones that in their economic effect come so close to the invalid provision(s) that it can be reasonably assumed that the Parties would have contracted on the basis of the new provision(s). If such provision(s) cannot be found, the invalidity of one or several provisions of the Agreement shall not affect the validity of the Agreement as a whole, unless the invalid provision(s) is of such essential importance for the Agreement that it is reasonably assumed that the Parties would not have entered the Agreement without the invalid provision(s).

14.2 Assignment

14.4 Amendments

Amendments of any provisions of the Agreement are only valid if they are in written form and signed by both Parties (electronic signature would suffice).

14.5 Independent Contractors; Third Party Rights

14.5.1 Nothing in this Agreement is intended to, or shall be deemed to, establish any partnership or joint venture between any of the Parties, make a Party the employer, employee, agent or representative of the other Party, or authorize any Party to enter into any obligations with third parties for or on behalf of the other Party, except as expressly provided in the Agreement.

14.5.2 Each Party confirms that it is acting on its own behalf only and not for the benefit of any other person. No person who is not a Party to the Agreement shall have any right under the Agreement. 

14.6 Disputes Procedure

14.6.1 Exclusive Dispute Resolution Mechanism. The Licensee shall resolve any dispute, controversy, or claim arising out of or relating to this Agreement, or the breach, termination or invalidity hereof (each, a "Dispute"), under the provisions of this clause 14.6 (Disputes Procedure). The procedures set forth in this clause 14.6 shall be the exclusive mechanism for resolving any Dispute that may arise from time to time and should serve as an express condition precedent to litigation of the Dispute.

14.6.2 Negotiations. Licensee shall send a written notice to the Licensor of any Dispute ("Dispute Notice") by email to or by recorded delivery post to Licensor’s registered address. The parties shall first attempt in good faith to resolve any Dispute set forth in the Dispute Notice by negotiations between Licensee and Licensor’s sales representatives during at least 2 (two) negotiation sessions attended by representatives of both parties either remotely or in person. 

14.6.3 Escalation. If the Dispute is not resolved within fourteen (14) calendar days from the date the Dispute Notice was delivered to the sales representatives of Licensor, Licensee shall escalate the dispute to the Licensor’s management by email to or by post to Licensor’s registered address. The parties shall attempt in good faith to resolve the Dispute set forth in the Dispute Notice by direct negotiations with Licensor’s management. If the Licensor’s management cannot resolve the Dispute during the time period ending fourteen (14) calendar days after the date of the escalation to the management was delivered to the Licensor either party may initiate mediation under clause 14.6.4. At Licensor’s discretion and written confirmation, the Disputes Procedure can be shortened. 

14.6.4 Mediation. The parties may, at any time after the completed escalation process set out in clauses 14.6.2 and 14.6.3, submit the Dispute to any mutually agreed mediation service for mediation by providing to the mediation service a joint, written request for mediation, setting forth the subject of the dispute and the relief requested. The parties shall cooperate with one another in selecting a mediation service, and shall cooperate with the mediation service and with one another in selecting a neutral mediator and in scheduling the mediation proceedings. The parties covenant that they will use commercially reasonable efforts in participating in the mediation. The parties agree that the mediator’s fees and expenses and the costs incidental to the mediation will be shared equally between the parties and shall be pre-agreed before they are incurred.

The parties further agree that all offers, promises, conduct, and statements, whether oral or written, made in the course of the mediation by any of the parties, their agents, employees, experts, and attorneys, and by the mediator and any employees of the mediation service, are confidential, privileged, and inadmissible for any purpose, including impeachment, in any litigation, or other proceeding involving the parties, provided that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its use in the mediation.

14.6.5 Litigation as a Final Resort. If the parties cannot resolve any Dispute for any reason, including, but not limited to, the failure of either party to agree to enter into mediation or agree to any settlement proposed by the mediator, within 28 calendar days after the escalation to the mediation stage set out in clause 14.6.4, either party may file a court claim in a court of competent jurisdiction.

14.6.6 No class actions. Licensee may only resolve disputes with Licensee on an individual basis, and may not bring a claim as a claimant or a class member in a class, consolidated, or representative action. Nonetheless, if any portion of this class action waiver is deemed unenforceable or invalid as to a particular remedy, then that remedy (and only that remedy) must be severed from the alternative dispute resolutions (“ADRs”) and may be sought in court. The parties agree, however, that any adjudication of remedies not subject to ADRs shall be stayed pending the outcome of any ADRs claims and remedies.

14.7 Force Majeure

Neither Party shall be in breach of the Agreement nor liable for delay in performing, or failure to perform, any of their obligations under the Agreement, if such delay or failure results from events, circumstances or causes beyond their reasonable control, such as, but not limited to, a governmental act, fire, explosion, earthquake, flood or other natural disaster, epidemic or pandemic, accident, civil commotion or industrial dispute or similar occurrence (“Force Majeure Event”). The time for performance of such obligations shall be extended for the duration of the Force Majeure Event. If the period of delay or non-performance continues for three (3) months, the Party not affected may terminate the agreement by giving thirty (30) days' written notice to the affected Party.

14.8 International Trade Sanctions

14.8.1 Compliance with International Trade Restrictions (the “ITR”) including, in the United States, those administered by the Office of Foreign Asset Control (“OFAC”) is mandatory for Licensor and no exceptions to the ITR are permitted. In summary, the ITR takes into consideration applicable laws which may expose Licensor to the risk of sanctions or other penalties, including those that relate to export controls and designated parties (including parties regarded by OFAC as Specially Designated Nationals). The ITR affects, in particular (but not solely), certain transactions related to countries subject to sanction, prohibition or restriction under the UN Security Council Resolutions or under other applicable trade or economic sanctions, laws or regulations (collectively known as “Restricted Territories”). The Restricted Territories under the ITR may be subject to change in line with international trade restrictions. 

14.8.2  Licensor expects Licensee to carry out appropriate due diligence to ensure Licensee’s activities are in accordance with all applicable trade restrictions laws and regulations.
