WHEREAS, for the CCR and NHT project under consideration (the “Project”), Bharat Petroleum Corporation

Limited ("Owner”) has selected the Process for a new unit to be located at Mumbai refinery, India (“Unit”); and

WHEREAS, in order for Bidder to make a proposal to Owner for construction relating to the Project, and, if

selected, to perform all or part of the detailed engineering and/or supply of any item (as applicable) required by the Process for the implementation of the Project (the “Purpose”), Bidder desires to have access to information of IFP and/or Axens.

NOW THEREFORE in consideration of the promises and mutual covenants herein contained, the parties hereto

agree to the following: 1 Disclosure of information. Axens will furnish at its sole discretion to Bidder, or authorize Owner to disclose to

Bidder, the Confidential Information as defined in article 2 hereunder. 2 Confidential Information. All information, whether, technical, commercial, or otherwise, whether written or oral,

provided, directly or indirectly, by Owner or Axens to Bidder under this Agreement, or which Bidder might acquire or discover during visits to facilities of IFP, Axens or third parties where such information is designed or exploited, or during discussions with Axens, IFP and/or Owner, together with all analyses, compilations, forecasts, studies or other documents that contain or otherwise reflect such information, shall be deemed the “Confidential Information” hereunder.

3 Use of Confidential Information. All Confidential Information received hereunder shall be kept confidential and shall not, without the prior written consent of Axens, be disclosed by Bidder, in any manner whatsoever, in whole or in part, and it shall not be used by Bidder, other than for the Purpose. Moreover, Bidder shall only disclose the Confidential Information to its officers, directors and employees who need to know such Confidential Information for the Purpose, who are informed by Bidder of the confidential nature of the Confidential Information and who shall be bound to act in accordance with the terms and conditions of this Agreement.

4 Ownership of Confidential Information. Bidder hereby agrees that the Confidential Information disclosed hereunder is and will remain the property of IFP and Axens and that drawings or other written, printed or electronic data included therein are not to be copied or reproduced, mechanically or otherwise, without the express permission of Axens, except for such copies that Bidder reasonably requires for the Purpose.

5 Non-Confidential Information. The term “Confidential Information” shall not include such information furnished hereunder that Bidder can prove:

a) was, at the time of disclosure, in the public domain or which subsequently enters the public domain through no act or failure to act by Bidder; or

b) was developed by or was in the possession of Bidder prior to being furnished to Bidder by Axens or on its behalf, provided that the source of such Confidential Information was not known to Bidder to be prohibited from disclosing the Confidential Information to Bidder by a legal, contractual or fiduciary obligation to Axens; or

c) Was or became available to Bidder on a non-confidential basis from a third party that is not known to Bidder to be prohibited from disclosing the Confidential Information to Bidder by a legal, contractual or fiduciary obligation to Axens.

However, in situations a) through c) above (the “Non-Confidential Information”), Bidder undertakes not to

disclose that any of such Non-Confidential Information lawfully in its possession is included in the Confidential Information.

6 The exceptions of article 5 shall not apply to any information furnished hereunder which: a) Is specific and, at the time of its disclosure hereunder, merely embraced by general information within the

exceptions, or b) Is a combination of features of the Confidential Information, unless the combination itself, its principle of operation

and method of use are within the exceptions.



7 Third-Party Disclosure. Despite the restrictions on disclosure contained in this Agreement, but only to the extent necessary for the Purpose, Bidder may disclose part of the Confidential Information to the following third parties:

a) a vendor of commodity equipment or materials or a supplier of construction labor who will receive only a minor or non-critical portion, as determined by Axens in its sole and absolute discretion, of the Confidential Information and who, prior to such disclosure, has signed an agreement with Bidder or Axens containing restrictions on use and disclosure at least equivalent to those contained in this Agreement; or

b) any other third party, including but not limited to, any detailed engineering contractor or manufacturer of specially-designed equipment, who, prior to such disclosure, has signed an agreement with Axens containing appropriate restrictions on use and disclosure;

c) an Affiliate of Bidder that needs to know Confidential Information in connection with the Purpose and who, prior to such disclosure, has been informed by Bidder of the confidential nature and of the confidentiality obligations attached to such Confidential Information; provided, however, that (a) Bidder warrants that such Affiliate shall respect said confidentiality obligation and (b) Bidder has notified to Axens the name of the Affiliates to which Bidder has disclosed Confidential Information under this Article 7c) immediately after such disclosure.

For the purpose of this Agreement, “Affiliate” means, in relation with any one of the parties, any company which,

directly or indirectly, controls, is controlled by, or is under common control with such party. A company is controlled by the ownership of more than fifty percent (50%) of its voting rights.

this Agreement becomes legally compelled (by oral questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process) to disclose any of the Confidential Information to third parties other than those identified above, Bidder will provide Axens with prompt notice so that Axens may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this Agreement. In any such event, Bidder will use its best efforts to ensure that the Confidential Information will be accorded confidential treatment.

9 Disclaimer of Warranties. Axens makes no representations and extends no warranties or conditions of any kind,

either express or implied, by operation of law or otherwise, with respect to the accuracy or completeness of the Confidential Information furnished hereunder.

to proceed with the construction of the Unit under contract with Bidder, whichever occurs first, Bidder will return to Axens or destroy, at Axens' option, all of the Confidential Information in Bidder's possession (including, all originals, and all copies and derivations therefrom, in any medium); provided, however, that Bidder may retain one copy of the Confidential Information in a locked and limited access file for the sole purpose of determining Bidder's compliance under this Agreement. If requested by Axens, an appropriate officer of Bidder will certify to Axens that all such material has been so returned or destroyed.

12 Term. Bidder's obligations under this Agreement to protect the Confidential Information from unintentional disclosure shall terminate 20 (twenty) years after Bidder's receipt of the Confidential Information in question.

13 No License. Nothing in this Agreement shall be construed as granting Bidder a license, an option on a license or

any right to operate under any patent, technology or know-how which IFP or Axens may, now or hereafter, have the right to license.

14 Governing Language. The governing language of this Agreement shall be English. 15 Governing Law. This Agreement and any dispute arising from the performance or breach hereof shall be governed

by and construed and enforced in accordance with the laws of Switzerland, without reference to conflict of law principles.

Agreement. Any dispute which cannot be solved through this process shall be settled finally according to the Rules of Arbitration of the International Chamber of Commerce by one or more arbitrators appointed in accordance with the said rules. Such arbitration shall be conducted in English and shall be held in Geneva, Switzerland, or any alternate mutually agreeable location. Judgment upon the awards rendered may be entered in any court having



jurisdiction thereof or application may be made to such court for a judicial acceptance of the awards and an order of enforcement as the case may be.

17 Assignment. This Agreement is not assignable in whole or in part by either party without the previous written

consent of the other party; provided, however, that it may be assigned by either party without such consent to a successor to substantially all of such party’s business assets, including that part concerned with this Agreement. Confidentiality and limited use obligations between the parties and the provisions with respect to dispute resolution and applicable law shall survive any assignment of this Agreement.

Section 5 - Previous Transgression (1) The Bidder declares that no previous transgression occurred in the last 3 years with any
