3. We are entitled to act in accordance with any obligation arising from Greek or European law under which we are required to disclose Confidential Information. This provision does not apply where Confidential Information has lawfully entered the public domain, or where we wish to disclose it to our professional liability insurers or advisors.

You should not rely on any oral, draft or interim advice without final written confirmation.

6. We are under no obligation to update any advice, report or deliverable due to events occurring after its final delivery, unless expressly provided for in the Agreement.

7. Any deliverable of the Services is provided solely for your benefit and information and may not be copied, reproduced or disclosed without our prior written consent, except for your internal use.

    - 7.2. We accept no liability or obligation to indemnify them in relation to our Services, to the fullest extent permitted by Greek law.

For the purposes of providing services to you or to other clients, we retain the right to use general knowledge, experience and skills acquired in the course of performing the Services, provided this does not affect your Confidential Information.

OUR FEES

11. For the Services, we will issue invoices inclusive of our fees, expenses and VAT (where applicable), as well as any other applicable taxes. Our fees are calculated based on the scope and complexity of the Services, the skills and time of the Working Team members. Any cost estimates or forecasts are indicative only.
Where we are required to provide information about you following a request from a regulatory body or legal proceedings, you agree to reimburse us for the costs incurred, provided we are not ourselves the subject of such proceedings.

12. You will pay our fees upon receipt of our invoice, without right of set-off, unless otherwise specified in the Proposal. In the event of late payment, SIGMAPRO reserves the right to charge interest in accordance with applicable legislation (Law 4152/2013 and Directive 2011/7/EU).
In the event of termination or suspension of the Agreement, we are entitled to recover expenses incurred and fees for work already performed, plus VAT, calculated on the basis of our hourly rates.

YOUR OBLIGATIONS

13. You are responsible for keeping us informed of:

    - Any decisions that affect the Services or your interests.

    - The provision of adequate resources and facilities for the performance of our work.

    - The provision of written confirmations/declarations where required.

    - Any cybersecurity incidents or data breaches that may affect the provision of the Services or Confidential Information shared with us.

14. Where we provide the Services at your premises or using your systems, you shall ensure the necessary access, security procedures, virus checks and any required licences or approvals, at no cost to us.

15. You may not directly or indirectly offer employment to any member of the Working Team involved in the provision of the Services, during the term of the Agreement or for 12 months following its completion, without our prior written consent. This restriction does not prevent you from publishing general recruitment advertisements.

INFORMATION AND CYBERSECURITY

16. For the provision of the Services, you shall provide us in a timely manner with all information, assistance and access to documents and personnel under your control. You shall also keep us informed of any developments that may affect the Services and provide information in response to our queries to enable us to comply with our anti-money laundering obligations.

17. In the event of communication by email or other digital means, you accept the inherent risks of such means (interception, unauthorised access, alteration, malware). SIGMAPRO accepts no liability for damages arising from such risks where it is not at fault.

18. Both parties are required to implement appropriate technical and organisational security measures to protect data exchanged in the context of the Agreement, in accordance with the requirements of the NIS2 Directive and the GDPR. In the event of a data breach, the affected party must notify the other party immediately and no later than within 72 hours.

19. We may rely on instructions, requests and information provided by persons whom we in good faith believe to be authorised by you ("Authorised Person"). We recommend the implementation of identification procedures (e.g. multi-factor authentication) for the authorisation of critical instructions, particularly those involving financial transactions.

KNOWLEDGE AND CONFLICTS OF INTEREST

20. The Working Team is not required to know or use information known to other Members of SIGMAPRO that is confidential to another client.

21. SIGMAPRO maintains mechanisms ("Information Barriers") to protect the interests of each client, such as separate working teams, geographic separation, functional independence, separate information systems and separate communications systems. Information Barriers now also include digital access control tools for technology and AI platforms.

22. We continuously seek to identify Conflicts of Interest. If you become aware of any such conflict, you are obliged to notify us promptly. We will not accept instructions that give rise to Conflicts of Interest for the Working Team. Similar provisions apply in relation to your Competitors, with appropriate Information Barriers activated in each case.

THE SERVICE AGREEMENT

23. The Agreement sets out the entirety of our agreement. Any amendments must be made in writing and signed by an authorised representative of both parties. In the event of any inconsistency, the Proposal prevails over the General Terms and Conditions, and any Additional Terms prevail over the General Terms and Conditions.

THIRD PARTY RIGHTS

24. The Agreement does not create, nor is it intended to create, rights in favour of third parties. No third party is entitled to enforce or rely on any provision of the Agreement. Members of SIGMAPRO are not considered third parties for the purposes of this clause.

FORCE MAJEURE AND EXTRAORDINARY EVENTS

25. Neither party shall be deemed to have breached its contractual obligations in the event of inability to comply due to events beyond its reasonable control ("Force Majeure"). Such events include, without limitation: natural disasters, armed conflicts, pandemics, legislative changes, large-scale digital infrastructure disruptions (e.g. large-scale cyberattacks), or other events that cannot reasonably be foreseen or prevented. The affected party must notify the other party as soon as possible, which shall have the right to suspend or terminate the Agreement.

WAIVER, ASSIGNMENT AND SUBCONTRACTORS

26. Failure by either party to exercise any right shall not constitute a waiver thereof.

27. Neither party is entitled to assign any rights or obligations without the written consent of the other.

28. We reserve the right to appoint subcontractors, having informed you in advance where they are not Members of SIGMAPRO. We assume full responsibility for their work.

EXCLUSION AND LIMITATION OF LIABILITY

29. All Members of SIGMAPRO exclude liability for any indirect or consequential financial loss or damage (including loss of profits), regardless of cause, except in cases of fraud or wilful misconduct.
The total liability of SIGMAPRO for direct loss or damage is limited to the amount specified in the Proposal or, in the absence thereof, to the amount of fees paid. In any event, the minimum threshold provided by law, if any, shall apply.

30. SIGMAPRO's liability is reduced proportionally, taking into account any contributory negligence or responsibility of any other party.

31. You may not bring personal claims against individual directors, officers or employees of SIGMAPRO. Any claim must be brought within five (5) years from the date on which you acquired the right to bring it.

THIRD PARTIES – INDEMNITY

32. You shall indemnify Members of SIGMAPRO against any loss, damage or expense arising from your breach of your obligations under the Agreement, where such breach gives rise to a claim by a third party or Other Beneficiary. This provision does not apply where we have given written consent to the disclosure and the agreed terms have been complied with.

TERMINATION

33. Either party may terminate the Agreement at any time upon not less than 30 days' prior written notice, unless prohibited by law. Upon termination, all amounts due to us become immediately payable.
We retain working papers supporting our reports, recommendations and opinions for a period of up to ten (10) years from the completion of our work, unless otherwise required by law. Personal data will be retained in accordance with GDPR requirements and applicable legislation.

PARTIAL INVALIDITY

34. Each clause of the Agreement constitutes a separate and independent provision. Invalidity of any clause or part thereof shall not affect the validity of the remaining provisions. The parties shall seek to agree a replacement provision that is legally valid.

GOVERNING LAW AND DISPUTE RESOLUTION

35. This Agreement is governed by Greek law. Any disputes arising from or in connection with this Agreement shall be subject to the exclusive jurisdiction of the courts of Athens, unless otherwise specified in the Proposal. The parties may agree in writing to refer disputes to mediation or arbitration in accordance with applicable legislation (Law 4640/2019 on mediation).
