In such situations, Customer remains responsible for the acts or omissions of its client’s use of the Service as it they were Customer’s own and Customer must ensure that its client enters into a set of terms that are pre-approved by Tax Optimiser).  Subject to the foregoing, Customer agrees that it will not: (a) permit any third party (other than its professional tax or finance advisors) to access and/or use the Service; (b) rent, lease, loan, or sell access to the Service to any third party; (c) interfere with, disrupt, alter, translate, or modify the Service or any part thereof, or create an undue burden on the Service or the networks or services connected to the Service; (d) reverse-engineer the Service (except to the extent that such restriction on reverse engineering is prohibited by law and then Customer shall provide Tax Optimiser with prompt written notice prior to any such action), or access the Service to build a competitive product or service; or (e) introduce software or automated agents or scripts to the Service so as to produce multiple accounts, generate automated searches, requests and queries, or to strip or mine data from the Service.

3.2              Sanitisation of Customer Reports.  Tax Optimiser agrees that before it discloses any Customer Report to any third party (including, without limitation, by archiving the contents of such report in the portions of the Tax Optimiser tax information database that are accessible by other customers of Tax Optimiser), it will first (a) remove all instances of Customer’s name from the substantive contents of such report; and (b) remove any references that identify Customer as the source of the Tailored Search Keywords that produced the Customer Report.

3.3              Ownership.  Subject to the rights expressly granted to Customer in Clause 3.1 (Customer Use of Tax Optimiser Data) above, as between Customer and Tax Optimiser, all Tax Optimiser Data, and all intellectual property and proprietary rights therein, shall be exclusively owned by Tax Optimiser.  There are no implied licences granted under this Agreement, and all rights not expressly granted are reserved.

5.                   CONFIDENTIALITY

5.1              “Confidential Information” means the Tax Optimiser Data and any nonpublic information regarding the Service.  Customer will not use any Confidential Information for any purpose not expressly permitted by this Agreement, and will disclose the Confidential Information only to (a) the employees and agents of Customer who have a need to know such Confidential Information for purposes of this Agreement and who are under a duty of confidentiality no less restrictive than Customer’s duty hereunder; and (b) third parties, only in the form of limited excerpts, to the extent permitted by the licence expressly set out in Clause 3.1.  Customer will protect the Confidential Information from unauthorised use, access, or disclosure in the same manner as Customer protects its own confidential or proprietary information of a similar nature and with no less than reasonable care.  Customer will be allowed to disclose the Confidential Information to the extent that such disclosure is (i) specifically approved in writing by Tax Optimiser, (ii) necessary in the course of legal proceedings for Customer to defend itself or to enforce its rights under this Agreement; or (iii) required by law or by the order of a court or similar judicial or administrative body, provided that Customer notifies Tax Optimiser of such required disclosure promptly and in writing and cooperates with Tax Optimiser, at Tax Optimiser’s reasonable request and expense, in any lawful action to contest or limit the scope of such required disclosure.  Customer will return to Tax Optimiser or destroy all tangible copies of Confidential Information in Customer’s possession or control and permanently erase all electronic copies of Confidential Information promptly upon the expiration or termination of this Agreement, whichever occurs first, except to the extent necessary to permit Customer to exercise any licence right to the Tax Optimiser Data expressly surviving under Clause 7.3 (Effect of Termination).

The Parties acknowledge that the prices have been set and the Agreement entered into in reliance upon these limitations of liability and that all such limitations form an essential basis of the bargain between the Parties.

8.4              In accordance with the applicable laws, responsibility for submitting tax returns to the tax authorities, including for the Customer not intervening with ‘digital links’ (meaning an electronic or digital transfer or exchange of data between software programs, products or applications under HMRC’s Making Tax Digital requirements), rest with the Customer and Tax Optimiser shall not be liable for Customer’s acts or omissions.
