In addition to the referred provisions of the French Commercial Code, the disposal of performance shares should comply with applicable laws especially concerning insider trading which impose anyone holding privileged information to refrain from transferring or acquiring related shares. Information is considered “privileged” in case of specific information that has not been made public and if it were to be made public, would have a significant impact on the trading price of the relevant shares. The Beneficiaries are specifically reminded that the “Rules of Good Conduct” set up by the company (and available on the Group Intranet TPNET>Technip Group) define Restriction Periods which remain applicable to the disposal shares by Beneficiaries. The Rules apply in particular to the disposal of shares acquired pursuant to the provisions of article 6.1.2 for a period of six (6) months following the occurrence of any of the events mentioned thereto. 10. AMENDMENTS TO THE PLAN 10.1 Principle This Plan may be amended by the Board of Directors in particular as provided in the Annex in relation to the method of determination of the Reference Performance. No amendment may be made to this Plan without the Beneficiaries’ consent if it would be unfavorable to the Beneficiaries, unless this modification would result from new legislation or regulatory enactment or any other enforceable provision applicable to the Company. 10.2 Notifications For the needs of this Plan, notifications may be made by any means, including by internal mail, regular mail, or mail with acknowledgement of receipt or by electronic mail to the address or fax number indicated by the Beneficiary. 10.3 Provision invalid Should a provision be deemed invalid for any reason, the enforcement of the Plan will not be affected therefore and will be construed as closely as possible in accordance with the initial intent. 10.4 Amendment of the Plan according to local law The Board of Directors may decide, in light of the rules applicable in certain countries (particularly under tax laws) to provide, initially (on the Allocation Date) or subsequently, pursuant to the conditions set forth in this article, certain specific provisions with regard to Beneficiaries located in such countries. The specific provisions with regard to Beneficiaries concerned will be stated in the letters of Allocation of Shares. 11. BENEFICIARIES NON RESIDING IN FRANCE 11.1 As concerns Beneficiaries subject to taxation in the United States of America, the Plan shall be construed and enforced so that the Allocation, Acquisition and Sale of the performance shares shall not result in a differed compensation under Section 409A of the US Internal Revenue Code of 1986, as modified. 11.2 The Beneficiary’s eligibility to participate in the Plan, the Allocation /or Acquisition delivery of Shares are contingent on the Company and/or the companies in its Group obtaining the necessary or desirable local authorizations, statements or formality, in the relevant countries. As for the United States, while the Allocation and/or Acquisition of shares by an American resident is possible in accordance with current American tax and securities regulations, if there is a change to such regulations or the interpretation thereof, or their interpretation by the Company, making it impossible or inopportune the Allocation and the delivery of Shares to a American resident, the ability to acquire the shares or the delivery of shares may be suspended by the Company without prior notice. 11.3 More generally, if the legislation of the country in which the Beneficiary is located makes the delivery of the Shares to such Beneficiary impossible or inopportune, the Acquisition or the delivery of the Shares may be suspended without any prior notice by the Company. In the event that the ability to acquire the Shares is suspended due to local regulations, the Company may pay the affected Beneficiaries an amount equivalent to the net capital gain in euros or in local currency that they could have received in acquiring the Shares. 11.4 Neither the Allocation nor the Acquisition of Shares were or will be registered with the US Securities Exchange Commission or any other US Authority. Shares acquired for under this Plan may not be sold in the United States. Such shares may be sold only through Euronext Paris. 11.5 Each Beneficiary is responsible for being informed of the tax consequences (including social charges) as a result of the Performance Shares granted to him or her. All such taxes and social charges imposed on the Beneficiary shall be his or her sole responsibility. If upon Allocation and/or Acquisition or sale of Performance Shares Company of the Group is responsible for withholding tax or social charges for the account of the Beneficiary, he or she immediately accepts that the Company suspends the Acquisition and/or delays the delivery of Performance Shares or prohibits the sale of Performance Shares until the Beneficiary has made or arranged for payment of the required amount. Alternatively, the Company has the right to sell all or a portion of the Performance Shares in order to reimburse the amounts owed with the proceeds of such sales. 12. LANGUAGE AND LITIGATION This Plan is governed by French law. The English version of this Plan is established for information purposes only, for the use of the non-French speaking Beneficiaries. In the event of a discrepancy, the French version shall prevail. In case of conflict or litigation regarding its interpretation, validity or implementation, the parties will attempt to find an amicable settlement; if not, the dispute will be brought before the competent French court.

06/07 Performance Shares 2016 ANNEX METHOD OF DETERMINATION OF THE REFERENCE PERFORMANCE The acquisition by the Beneficiaries of the performance shares shall be conditional upon the achievement of a performance to be measured on 2016, 2017 and 2018 fiscal years by the results of the Group over three consecutive years in terms of Health Safety & Environment (HSE), Operating Income From Recurring Activities (OIFRA) and Total Shareholder Return (TSR) metric, considering that: • The HSE metric corresponds to the Total Recordable Case Frequency (TRCF) where TRCF = Number of recordable accidents / 200,000 working hours; • The OIFRA metric is the operating income from recurring activities, as reported in Technip’s Annual Report; • The Total Shareholder Return (TSR) is the rate of return of a share over a year, taking into account the payment of a dividend during the period. The dividend is assumed to be reinvested immediately into the share itself at the closing share price of the dividend payment day (definition used by Bloomberg); the calculated average for Technip over a given period to be compared with the calculated average of a sample of competitors. The performance obtained shall be measured, as a percentage (i) for the HSE metric, to the corresponding performance of the Group during a previous period, and (ii) for the second metric (OIFRA) to (1) a target expressed in absolute value precised by the Board of Directors and for the third metric (TSR) to the corresponding average performance of a sample of competitors. The Reference Performance shall be computed as the arithmetical average of the three metrics hereabovementioned. An independent expert appointed by the Board of Directors, upon consultation of the Nominations and Remunerations Committee will carry out the abovementioned Reference Performance calculation, according to the provisions of the Plan. The “At Risk Portion of the Plan” is made of the Performance Shares which might be lost by the Beneficiaries according to the levels of performance achieved and corresponding to 100% of the performance shares allocated to the Chairman and Chief Executive Officer and Senior Management Group (the “Chairman and Chief Executive Officer and Senior Management Group At Risk Portion”). The Reference Performance shall determine the definitive proportion of shares to be acquired based on the following scales: • if the Reference Performance is below 75%, the At Risk Portion of the Plan will be lost by Beneficiaries; • if the Reference Performance is at least equal to 75%, the percentage of the performance shares that will be exercisable in the At Risk Portion of the Plan will be defined on a straight line basis against the Reference Performance:—from 0 to 100% for the Group’s principal executives At Risk Portion. The performance shares which cannot be exercised due to the lack of performance will be definitively lost. The Board of Directors of the Company, by a duly justified decision and on the recommendation of the nominations and remunerations committee, may modify the method of determination of the reference performance in case of exceptional circumstances justifying such modification to neutralize, as far as possible, the consequences of such exceptional circumstances on the appreciation of the achievement of the performance. In particular, the Board of Directors may modify the method of determination of the reference performance in case of completion of the combination of Technip and FMC Technologies announced on May 19, 2016, to adapt the performance metrics to the new group. The Board of Directors may decide to modify, exclude or adjust the metrics composing the method of determination of the reference performance, while maintaining the overall consistency of the method and the objectives that have been set up at the time of the grant. In particular, the amendments of the method of determination of the reference performance shall have the objective to maintain the evaluation of the performance based on three metrics of which one metric related to Sustainable Development and two financial metrics among which an external one. The Beneficiary shall be duly informed. (1) The target value for the OIFRA is confidential data likely to have an influence of the share price which prohibits any ex ante disclosure even to the Beneficiaries. Conversely the calculation of the Reference Performance ex post, shall be fully disclosed based on actual reported figures.
