Subsea 7 — AGM Information 2017

Mar 15, 2017

Subsea 7 S.A. 412F, Route d'Esch L-2086 Luxembourg www.subsea7.com

15 March 2017

Dear Shareholder,

On Wednesday 12 April 2017, the Annual General Meeting of Shareholders (the "AGM") of Subsea 7 S.A. (the "Company") and an Extraordinary General Meeting of Shareholders (the "EGM") will be held at the registered office of the Company, 412F, route d'Esch, L-2086 Luxembourg. The AGM will be held at 15:00 (local time) and the EGM will be held immediately thereafter.

Due to the fact that the Company is incorporated in Luxembourg as a Société Anonyme, the Company's affairs are governed by the provisions of Luxembourg Company Law. Under these provisions and the provisions of the Company's Articles of Incorporation, the AGM and EGM will be restricted to the matters set out in the enclosed Notice.

Matters to be considered at the AGM

Firstly, I would like to take this opportunity to highlight that in light of the improving market outlook and the Group's strong financial and liquidity position, the Board of Directors will recommend to the shareholders at the AGM that a dividend of NOK 5.00 per share be paid.

In addition, I would like to highlight that this year's AGM agenda includes items in relation to the appointment to the Board of four Directors standing for re-election. The biographies of the relevant Directors, Mr Robert Long, Mr Allen Stevens, Mr Dod Fraser and myself are attached in the Appendix to this letter.

The agenda of the AGM will furthermore feature its standard items and in particular the approval of the Company's financial statements.

Matters to be considered at the EGM

Shareholders may be aware that during 2016 new legislation in relation to Luxembourg Company Law came into force. The purpose of this new legislation was the modernisation and clarification of the existing regime and one effect of this is that existing Luxembourg companies are required to make some updates to their Articles of Incorporation.

The sole purpose of the EGM is therefore to consider proposed amendments to the Company's Articles of Incorporation. The proposed changes are summarised below and their

seabed-to-surface

Registered Office: 412F, Route d'Esch L-2086 Luxembourg R.C.S. Luxembourg B 43172

effect is primarily to ensure conformity with the revised amended Luxembourg Company Law. These changes are, we believe, in shareholders' interests.

Article	Proposed change
2	An amendment to the rules regarding a transfer of the Company's registered office for the purpose of simplifying administrative procedures by the addition of the language shown in italics and bold:
	"The registered office of the Company is situated in Luxembourg. It may be transferred to any other place in the Grand Duchy of Luxembourg by resolution of the Board of Directors. In case the Board uses this authorisation it so shall have the power to amend these Articles of Incorporation accordingly."
5 Para (3)	A clarification to the rules regarding the fate of non-exercised preferential subscription rights in order to address a change in Luxembourg law, by the addition of the language shown in italics and bold:
	The Board of Directors or delegate(s) duly appointed by the Board may from time to time issue shares (or any securities or rights giving rights to shares) against contributions in kind or cash or by way of incorporation of available premium or reserves or in lieu of dividends or otherwise out of the total authorised unissued shares at such times and on such terms and conditions, including the issue price, as the Board of Directors or its delegate(s) may in its or their discretion resolve. The holders of Common Shares shall be entitled to preferential subscription rights in respect of any future issue of Common Shares for cash. In case of a future issue of Common Shares for cash with preferential subscription rights, where not all such rights shall have been exercised by the end of the subscription period, the Board of Directors may determine (i) that the shares not subscribed may be subscribed to by or placed with such person or persons as determined by the Board of Directors or (ii) that such unexercised rights may be exercised in priority in proportion to the capital represented by their shares, by the existing shareholders who have exercised their rights in full during the preferential subscription period. In such case, the terms of the subscription by or placement with such person or the subscription terms of the existing shareholders shall be determined by the Board of Directors. Without prejudice to decisions of the Board taken under a previous authorisation, the Board of Directors may within the limit of the authorised unissued share capital for a maximum of thirty three million two hundred sixteen thousand seven hundred six (33,216,706) Common Shares suppress, limit or waive the preferential subscription rights of the shareholders to the extent it deems relevant, and in particular:
5 Para (7) and (8)	The addition of two new paragraphs in relation to the allocation of free shares to employees and officers of the Company (for instance under an employee incentive plan) which have been included following changes in Luxembourg law which now require the power to the Board of Directors to allocate such shares to expressly be included in the Articles of Incorporation. The new paragraphs will read as follows:
	"The Board of Directors may allocate new shares issued under the authorised share capital or existing Common Shares free of charge to employees and corporate officers (including directors) of the Company and of any entity consolidated by the Company as permitted by applicable law.
	The Board of Directors shall approve the terms and conditions of such allocations."

12 Para (3)	The Luxembourg legislation regarding signature requirements for bond certificates has been amended so the following changes to the Articles of Incorporation are proposed to align the wording with the legal position (shown in italics and bold):
	"If certificates for bonds or debentures shall be issued, they shall be signed by two Directors at least one Director or the person or persons delegated for that purpose by the Board of Directors of the Company, manually or by facsimile."
15 Para (5)	An amendment to adjust the minimum quorum requirement in case of a conflict of interest of Directors by the addition of the language shown in italics and bold
	"The Board of Directors may only deliberate validly if the majority of its members shall take part in the proceedings by voting personally, by telephone or by video conference or by proxy given in writing, by telegram, fax or e-mail. If one or more Directors are prevented from participating in the deliberations of the Board of Directors by reason of a conflict of interest, the required quorum will be the majority of non-conflicted Directors."
24 Para (1)	The removal of a fixed date and time for the annual general meeting of shareholders and replacement with a requirement to convene the annual general meeting within six months of the previous financial year, so the wording reads as follows:
	"The annual general meeting shall be convened in the municipality of the registered office within six (6) months from the end of the previous financial year."
26 Para (7)	An update to the convening requirements in relation to the general meeting by the addition of wording shown in italics and bold:
	"Notices for general meetings shall be given by advertisement in such media as selected by the Board of Directors and:
	…
	b) by mail, postage prepaid, to all holders of Common Shares, sent to the address recorded in the Register(s) (except those shareholders who have accepted to receive the convening notice by e-mail (and not withdrawn their acceptance at least 60 days before the relevant general meeting)), and posted (or sent by e-mail) not later than twenty one (21) days before the date set for the meeting."
28	An update to the wording regarding the Company's financial year to remove a now obsolete reference to the 2010/2011 financial year so that the revised paragraph reads as follows (changes shown in italics and bold):
	"The financial year starting on 1st December 2010 will end on 31st December 2011. Thereafter, Tthe Company's financial year shall begin on the first day of January and end on the 31 st day of December in each year."

Quorum and Majority

At the AGM, since under Luxembourg law there is no minimum quorum requirement, decisions taken shall be valid regardless of the number of shares represented, provided there is approval by the majority of the votes of the shareholders validly cast.

The EGM shall validly deliberate on its agenda provided a quorum of 50% of the issued share capital of the Company is present or represented. If a quorum is not achieved, a second extraordinary general meeting of shareholders may be called with the same agenda, at which there would be no quorum requirement. Resolutions concerning the agenda of the EGM shall be adopted by a majority of two-thirds of the votes validly cast.

General Matters

Holders of Common Shares and American Depositary Receipts on record at the close of business on 8 March 2017 will be entitled to vote at the AGM. The deadline for submission of votes for holders of American Depositary Shares is 5 April 2017 and for holders of Common Shares is 7 April 2017.

Enclosed with this mailing are the Notice of Annual General Meeting and Extraordinary General Meeting of Shareholders, and Proxy Card.
