Listing Particulars dated February 20, 2018
NOT FOR GENERAL CIRCULATION
IN THE UNITED STATES

CGG S.A.
US$355,141,000 and 80,372,000 Floating Rate / 8.5% PIK Second Lien
Senior Secured Notes due 2024
(up to US$588.2 million and 133.1 million, respectively, after issuance of
additional notes for PIK Interest)
Guaranteed on a senior basis by certain subsidiaries
We are offering US$355,141,000 and 80,372,000 initial principal amount of our floating rate / 8.5% payment-in-kind ("PIK") Second Lien Senior Secured Notes
due 2024 (the "Offered Notes"). The Offered Notes comprise (a) US$274,975,000 and 80,372,000 in aggregate principal amounts of Offered Notes issued pursuant
to the Private Placement Agreement (as defined herein) (together, the "New Money Second Lien Notes") and (b) US$80,166,000 in aggregate principal amount of
Offered Notes to be settled by way of set-off of claims only against interest claims under Senior Notes (as defined herein) (the "Second Lien Interest Notes"). The
terms and conditions of the New Money Second Lien Notes and the Second Lien Interest Notes will be identical. As further described herein, in addition to cash
interest, the Offered Notes will accrue PIK interest ("PIK Interest") through the issuance of Additional Notes (the Offered Notes, together with any Additional
Notes, the "Notes"). Assuming the Notes remain outstanding until maturity, the aggregate principal amounts of Notes (taking into account the Offered Notes and the
Additional Notes to be issued in connection with the payment of PIK Interest) will be approximately US$588.2 million and 133.1 million. The New Money Second
Lien Notes will be issued concurrently with warrants (the "Warrants") entitling the holders of the Warrants to purchase, subject to certain conditions, our new
ordinary shares. The Notes will mature on February 21, 2024.
Interest on the Notes will accrue from February 21, 2018 as follows: (a) for Notes denominated in US dollars, (i) cash interest at a rate of LIBOR (subject to a floor
of 1.00%) + 4.00% per annum and (ii) PIK Interest at a rate of 8.50% per annum; and (b) for Notes denominated in euros, (i) cash interest at a rate of EURIBOR
(subject to a floor of 1.00%) + 4.00% per annum and (ii) PIK Interest at a rate of 8.50% per annum. Interest on the Notes will be payable (in case of cash interest) or
capitalized through the issuance of Additional Notes (in case of PIK Interest) quarterly in arrear each February 21, May 21, August 21 and November 21,
commencing on May 21, 2018. The initial principal amount of the Notes will accrue to the extent of the capitalized PIK Interest on a quarterly basis. Upon payment
of PIK Interest, a notice shall be published on the website of the Luxembourg Stock Exchange in the form of Appendix 1. We may redeem all or part of the Notes at
the redemption prices described in these listing particulars. We may redeem all, but not less than all, of the Notes at a redemption price equal to 100% of the
principal amount of the Notes in the event of certain changes in tax laws. If we undergo a change of control, each holder may require us to repurchase all or a portion
of the Notes at 101% of the principal amount thereof, plus accrued and unpaid interest.
The Notes will be our senior secured obligations and will be initially guaranteed on a senior secured basis by certain of our subsidiaries. The Notes will be senior
secured obligations of the guarantors secured by a lien, subject to certain exceptions and permitted liens, on certain of our and the guarantors' existing and future
assets. In the event of enforcement of the lien securing the Notes and the Subsidiary Guarantees (as defined below), the proceeds thereof will first be applied to
repay obligations secured by senior priority liens, including the First Lien Notes (as defined herein). The Notes will be effectively junior to all obligations of our
subsidiaries that do not guarantee the Notes.
The Notes will be represented on issuance by one or more global notes, which we expect will be delivered through Euroclear Bank SA/NV ("Euroclear") and
Clearstream Banking S.A. ("Clearstream"), on or about February 21, 2018.
Application has been made to admit the Notes to listing on the Official List of the Luxembourg Stock Exchange and to trading on the Euro MTF market ("Euro
MTF"). These listing particulars constitute a Prospectus for the purpose of Luxembourg law dated July 10, 2005 on Prospectuses for Notes, as amended. The
Warrants will not be listed on any regulated or non-regulated market. For additional information regarding the Warrants, see Section 4.4.2 of the Safeguard Plan in
our report on Form 6-K submitted to the Commission on August 7, 2017 incorporated by reference herein.
Investing in the Notes involves risks. See "Risk Factors" beginning on page 28.
The New Money Second Lien Notes have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"), or the laws
of any other jurisdiction, and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (as defined in Regulation S
under the Securities Act ("Regulation S")) except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities
Act. In the United States, the New Money Second Lien Notes are being offered only to "qualified institutional buyers" (as defined in Rule 144A under the Securities
Act ("Rule 144A")) ("QIBs") that have entered into the Private Placement Agreement (including by execution of the Joinder Agreement (as defined herein)) in a

in reliance on Regulation S. The New Money Second Lien Notes are subject to certain restrictions on sales, offers, subscription and transfer set out in Schedule 4 of
the Private Placement Agreement.
The Second Lien Interest Notes have not been and will not be registered under the Securities Act or the securities laws of any other jurisdiction. The Second Lien
Interest Notes will be issued pursuant to an exemption from registration under Section 1145 of the Bankruptcy Code ("Section 1145").

Company accepts responsibility for the information contained or incorporated by reference in these listing
particulars.
These listing particulars do not constitute an offer to sell or an invitation to subscribe for or purchase any of
the Notes in any jurisdiction in which such offer or invitation is not authorized or to any person to whom it is
unlawful to make such an offer or invitation. No action has been, or will be, taken to permit a public offering
in any jurisdiction where action would be required for that purpose. Accordingly, the Notes may not be
offered or sold, directly or indirectly, and these listing particulars may not be distributed, in any jurisdiction

particulars. You must also obtain any consents or approvals that you need in order to purchase, offer or sell

any of the foregoing legal requirements.
For the offering of the New Money Second Lien Notes, we are relying on exemptions from registration under
the Securities Act for offers and sales of securities that do not involve a public offering. In the United States,
the New Money Second Lien Notes are being offered only to QIBs that have entered into the Private
Placement Agreement (including by execution of the Joinder Agreement) in a private placement exempt from
the registration requirements of the Securities Act. Outside the United States, the New Money Second Lien
Notes are being offered in reliance on Regulation S. The Second Lien Interest Notes will be issued pursuant to
an exemption from registration under Section 1145.
Neither we nor any of our representatives are making an offer to sell the Notes in any jurisdiction except
where an offer or sale is permitted. You should understand that you will be required to bear the financial risks
of your investment for an indefinite period of time. These listing particulars are based on information
provided by us and by other sources that we believe are reliable. We cannot assure you that this information is

content.
The information contained or incorporated by reference in these listing particulars speaks as of the date hereof

any subsequent commitment to purchase the Notes shall, under any circumstances, create an implication that

1



there has been no change in the information set forth in these listing particulars or in our business since the
date of these listing particulars.
Neither we nor any of our representatives are making any representation to you regarding the legality of an
investment in the Notes by you under any legal, investment or similar laws or regulations. You should not
consider any information in these listing particulars to be legal, financial, business, tax or other advice. You

You should contact us with any questions about this offering or if you require additional information to verify
the information contained or incorporated by reference in these listing particulars.
The Notes have not been approved or disapproved by the U.S. Securities and Exchange Commission (the
"Commission" or the "SEC"), any state securities commission in the United States or any other U.S.
regulatory authority, nor have any of these authorities passed upon or endorsed the merits of this offering or
the accuracy or adequacy of these listing particulars. Any representation to the contrary is a criminal offense
in the United States.
Interests in the Notes will be available initially in book-entry form. We expect that the Notes sold will be
issued in the form of one or more global notes. The global notes sold in reliance on Regulation S under the
Securities Act ("Regulation S") will be represented by one or more global notes in registered form without
interest coupons attached (the "Regulation S Global Notes"). The global notes sold to QIBs in a private
placement exempt from the registration requirements of the Securities Act will be represented by one or more
global notes in registered form without interest coupons attached (the "Rule 144A Global Notes"). The
Second Lien Interest Notes may be represented by one or more global notes in registered form without
interest coupons attached (the "Section 1145 Global Notes" and, together with the Rule 144A and the
Regulation S Global Notes, the "Global Notes"), or otherwise by either the Regulation S Global Notes or the
Rule 144A Global Notes, in accordance with the election made by relevant initial holders of such Second Lien
Interest Notes. The Global Notes will be deposited with, or on behalf of, a common depositary for the
accounts of Euroclear and Clearstream and registered in the name of the nominee of the common depositary.
Transfers of interests in the Global Notes will be effected through records maintained by Euroclear and
Clearstream and their respective participants. The Notes will not be issued in definitive registered form except
under the circumstances described in "Book-Entry, Delivery and Form".
These listing particulars set out the procedures of Euroclear and Clearstream in order to facilitate the original
issue and subsequent transfers of interests in the Notes among participants of Euroclear and Clearstream.
However, neither Euroclear nor Clearstream is under any obligation to perform or continue to perform such
procedures and such procedures may be modified or discontinued by any of them at any time. Neither we nor
any of our agents will have responsibility for the performance of the respective obligations of Euroclear,
Clearstream or their respective participants under the rules and procedures governing their operations, nor
will we or our agents have any responsibility or liability for any aspect of the records relating to, or payments
made on account of, book-entry interests held through the facilities of any clearing system or for maintaining,
supervising or reviewing any records relating to these book-entry interests. Investors wishing to use these
clearing systems are advised to confirm the continued applicability of their rules, regulations and procedures.
These listing particulars have not received the visa of the French Autorité des Marchés Financiers ("AMF")
and accordingly may not be used in connection with any offer or sale of the Notes to the public in France.
We have not published a prospectus in relation to the Notes pursuant to Directive 2003/71/EC (together with
any applicable implementing measures in any Member State of the European Economic Area ("EEA"), the
"Prospectus Directive") and are offering the Notes only in those Member States that have implemented the

2



Prospectus Directive in reliance on exemptions from the obligation to publish a prospectus provided in Article
3(2) of the Prospectus Directive. We have not authorized the making of any offer of Notes through any
financial intermediary.
The Notes will be considered to be issued with original issue discount ("OID") for U.S. federal income
tax purposes. Accordingly, U.S. holders generally will be required to include such OID in gross income
(as ordinary income) on an annual basis under a constant yield accrual method regardless of their
regular method of accounting for U.S. federal income tax purposes. As a result, U.S. holders generally
will include any OID in income in advance of the receipt of cash attributable to such income. U.S.
holders should consult their tax advisers regarding the U.S. federal income tax consequences of holding
the Notes, including the application of the OID rules.

amendments or supplements. While any of the Notes remain outstanding, we will make available, upon

FORWARD-LOOKING STATEMENTS
These listing particulars include "forward-looking statements" within the meaning of the federal securities
laws, which involve risks and uncertainties. You can identify forward-looking statements because they contain
words such as "believes", "expects", "may", "should", "seeks", "approximately", "intends", "plans",
"estimates", or "anticipates" or similar expressions that relate to our strategy, plans or intentions. These
forward-looking statements are subject to risks and uncertainties that may change at any time, and, therefore,
our actual results may differ materially from those that we expected. We have based these forward-looking
statements on our current views and assumptions about future events. While we believe that our assumptions
are reasonable, we caution that it is very difficult to predict the impact of known factors, and, of course, it is
impossible for us to anticipate all factors that could affect our actual results. All forward-looking statements
are based upon information available to us on the date of these listing particulars.
Important factors that could cause actual results to differ materially from our expectations ("cautionary
statements") are disclosed under "Risk Factors" and elsewhere in these listing particulars, including, without
limitation, in conjunction with the forward-looking statements included or incorporated by reference in these
listing particulars. All forward-looking information in these listing particulars and subsequent written and oral
forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their
entirety by the cautionary statements. Some of the factors that we believe could affect our actual results
include:
·
the ability to consummate the plan of reorganization in accordance with the terms of the Safeguard
Plan and the Chapter 11 plan;
·
the effects of bankruptcy processes on our business and on the interest of various constituents;
