Discussions with the stakeholders

Following the February 27, 2017 appointment by the President of the Paris Commercial Court of Maître Bourbouloux as mandataire ad hoc, discussions took place with the Group's principal creditors aimed at reducing the Group's debt. CGG ,some of its principal creditors, and DNCA (in its capacity as long-term institutional shareholder and holder of the Company's Senior Notes and Convertible Bonds) reached an agreement in principle on a financial restructuring plan on June 1, 2017 and, legally binding agreements (lock-up or restructuring support agreements) were signed on June 13, 2017 which confirmed the agreement in principle, whereby the parties thereto have committed to undertake any action reasonably required to implement and carry out the restructuring.

To the Company's knowledge, as of October 4, 2017, no member of the ad hoc Senior Notes holders committee or of the ad hoc Secured Lenders committee held more than 1 % of the Company's capital. At this date, DNCA who held (i) approximately 5.5 % of the total principal amount of the Senior Notes, (ii) approximately 20.7 % of the total principal amount of the

Convertible Bonds, and (iii) approximately 7.9 % of the share capital of the
Company.

The draft safeguard plan was approved on July 28, 2017 by a unanimous vote of the committee of banks and financial institutions, and by a majority of 93.5% of votes cast at the general meeting of bondholders, including by DNCA. The "Chapter 11" plan concerning the various classes of creditors subject to "Chapter 11" proceedings was confirmed by the relevant US court on October 10, 2017 (the order should be entered in the next few days). The works council of the Company, also consulted with respect to the draft safeguard plan, rendered a favorable opinion at its meeting held on October 2, 2017.

In order to implement the draft of the restructuring plan, the required resolutions will first have to be approved by the Company's general meeting of shareholders, which is scheduled to convene on October 31, 2017. The plan will then have to be sanctioned by a judgment of the Paris Commercial Court, scheduled for November 13, 2017, according to the indicative timetable, following a hearing on November 6, 2017. The judgment by the Paris Commercial Court on the safeguard plan will then have to be recognized in the United States under a Chapter 15 proceeding, which is tentatively expected to take place on November 20, 2017.

A Chapter 11 plan concerning some of the Group's foreign subsidiaries, which are debtors or guarantors of the Group's debt has been prepared. The subsidiaries involved in the Chapter 11 plan are CGG Holding BV, CGG Marine BV, CGG Holding I (UK) Ltd, CGG Holding II (UK) Ltd, CGG Holding (US) Inc., CGG Services (US) Inc., Alitheia Resources Inc., Viking Maritime Inc., CGG Land (US) Inc., Sercel Inc., Sercel-GRC Corp, CGG Marine Resources Norge AS, CGG Canada Services Ltd and Sercel Canada Ltd.

As part of these judicial proceedings, the holders of claims under the Secured Loans, the Senior Notes and the Convertible Bonds whose principal aggregate amount, inclusive of the Convertible Bonds, is approximately equal to \$2.8 billion) may not demand any early repayment, which provides protection to the Group to carry out its operational activities while leaving to stakeholders only a limited timeframe to approve a financial restructuring plan.

Should one of the conditions set out in subsection C.1of the Prospectus Summary fail to be satisfied, the financial restructuring plan may not be implemented. In this case, or if the implementation timetable is not met, according to the Company cash flow forecasts, the Group liquidity would decrease below the required level to continue the operations no later than the first quarter of 2018, hence jeopardizing the ability of the Group to continue as a going concern. In addition, in such cases, the Group could be placed under judicial reorganization proceedings (redressement judiciaire) in the short term, and be wound up in the medium term, as the case may be in the

context of liquidation proceedings in various jurisdictions. Should such proceedings be carried out, they could place the shareholders and the holders of American Depositary Shares in a situation where they would lose their entire investment in the Group, and the creditors, or some of them, with fewer recourses to recover their claims
For the purpose of the Prospectus Summary, (i) "Restructuring Effective Date" means the date on which all of the conditions relating to the effective nature of the completion of the restructuring plan under the US proceeding of Chapter 11 of the Federal Bankruptcy Code and the safeguard (sauvegarde) or judicial reorganization proceedings (redressement judiciaire) plan (as applicable) have been satisfied or waived, including the completion of all steps required to finalize the restructuring, such as the issuance of debt securities and other securities contemplated therein, irrespective of the fact that the time limits for challenges have not expired, such date being acknowledged by the Board of directors or, upon delegation, by the CEO of the Company, and (ii) "Reference Date" means the date corresponding to the last day of the exercise period for the Rights Issue with PSR.
Summary of the main characteristics of the draft safeguard plan
The main characteristics of the draft safeguard plan are the following :
• The substantial reduction of the Company's gross financial indebtedness level by way of equitization of the claims under the Senior Notes and Convertible Bonds
Equitization of the Senior Notes
The claims under the Senior Notes (principal plus accrued interest o other than interest referred to below) would be equitized at their face value at a subscription price of €3.12 per new share (the "Creditors Shares 2") (except for the amount potentially used to backstop the capital increase with preferential subscription right as described below);
Accrued and unpaid interests under the Senior Notes for an amount of o \$86 million would be paid in new high-yield second lien notes or would be paid in cash over a ten-year period subject to certain terms.
Equitization of the Convertible Bonds The claims under the Convertible Bonds (principal plus accrued o interest other than interest referred to below) would be equitized at their face value at a subscription price of €10.26 per new share (the "Creditors Shares 1"); Accrued and unpaid interests for an amount of approximately €4.46 o million would be paid in cash.

	• A new money injection up to approximately \$500 million
	The size of such new money injections was discussed and agreed between the parties on the basis of negative sensitivities vis-à-vis the outlook for 2018 and 2019, based in particular on a less favorable assumption regarding the price per oil barrel, i.e. a simple stability compared to the current level of USD 50-55 per barrel, and a lower increase of exploration expenses.
	Share capital increase with preferential subscription right for
	approximately €112
	A share capital increase with preferential subscription right would be o implemented in an amount of up to approximately €112 million (the "Rights Issue with PSR") by way of an issue of new shares with share warrants attached (the "Warrants #2" and "ABSA"), at a subscription price of €1.56 per ABSA; three Warrants#2 would give the right to subscribe to two new shares at a price of €4.02 per new share, for a 5-year exercise period. This capital increase would be backstopped by DNCA Invest and the entities managed by DNCA Finance (the "DNCA Entities"), up to an amount of €71.39 million (compensated by a fee equal to 10 % of the amount backstopped), then by the holders of Senior Notes for the remaining portion unsubscribed by the shareholders, by way of set-off.
	Issuance of new high yield notes for an amount up to \$375 million
	An issuance of new high-yield second-lien notes would be o implemented for an amount of \$375 million, such issuance being subscribed in accordance with a private placement agreement dated June 26, 2017; the subscribers would benefit from an allocation of share warrants giving right to subscribe, with a six-month exercise period and for one euro cent (€0.01) per new share, to 16% of the capital on a partially diluted basis after the restructuring transactions (the "Warrants #3"). The new notes would be governed by New York state law, benefit from second-ranking security interests, and bear interest at a rate including a variable component indexed on the LIBOR for the tranche denominated in US dollars and EURIBOR for the tranche denominated in euros (with a floor at 1%) plus 400 bps per annum and PIK of 850 bps per annum (the "New Second Lien Notes)"; the subscribers would benefit from a backstop commitment fee equal to 7 % of the total amount subscribed;
	This issuance of new notes would be backstopped by the members of o
	the ad hoc committee of the holders of Senior Notes (or their
	transferees) who will receive in this respect a backstop commitment
	fee equal to 3 % of the total amount of the issuance, and share
	warrants giving the right to subscribe, with a six-month exercise
	period and for one euro cent (€0.01) per new share, to 1.5% of the capital on a partially diluted basis after the restructuring transactions
	(the "Backstop Warrants");
	The funds raised in cash from (i) the Rights Issue with PSR and (ii) o

the issue of the New Second Lien Notes and Warrants #3 (net of backstop and commitment fees and other costs, expenses or fees related to the Rights Issue with PSR and the issue of the New Second Lien Notes and Warrants #3) will be used as indicated in paragraph E.2a below.
• The free allocation of share warrants to the shareholders enabling them to benefit from the sector recovery
Share warrants would be allocated for free for each existing share (the o "Warrants #1"). Three of such warrants would give right to subscribe, with a four-year exercise period, for four new shares of the Company at a subscription price of €3.12 per new share.
• The free allocation of share warrants to the members the ad hoc committee of the holders of Senior Notes Share warrants would be allocated for free to the members of the ad
hoc committee of the holders of Senior Notes (the "Coordination
Warrants"). Such warrants would give the right to subscribe, with a
six-month exercise period and for one euro cent (€0.01) per new share,
to 1% of the capital on a partially diluted basis after the restructuring transactions.
• The extension of the maturity of the Secured Loans
The Secured Loans would be subject, under certain conditions, o partially repaid by anticipation up to \$150 million (the "Initial Repayment") by means of injection of new liquidity as described
above. The US RCF, the French RCF and the TLB 2019 would be o "exchanged" for new high-yield first lien notes, with a five-year maturity (2023), except in the event of early total repayment of the
Secured Loans. Such new high-yield first lien notes would be governed by the New o York State law and issued by CGG Holding (U.S.) Inc., and would bear interest at a rate with a floating LIBOR component (subject to a floor of 100 basis points) plus 650 basis point, in cash per year and, with respect to capitalized interest (payment-in-kind, or PIK), a component determined on the Restructuring Effective Date based on the amounts still outstanding on that date after taking into account the Initial Repayment, such bonds being issued (i) for the creditors of the US RCF and of the TLB 2019, and (ii) upon instruction from the Company, to the creditors under the French RCF as payment of part of
the debt owed by CGG Holdings (U.S.) to the Company;
The issuances of Warrants #1, ABSA, Warrants #3, Coordination Warrants and Backstop Warrants are below referred to as the "Issuances Steps".
The "Chapter 11" plan follows the characteristics of the draft safeguard plan

described below for the creditors concerned, that is to say the creditors under the Secured Loans and the Senior Notes (the "Chapter 11" plan and the draft safeguard plan are together referred to as the "Financial Restructuring Plan"). Financial debt and liquidity after completion of the transactions provided for in the Financial Restructuring Plan Following the transactions provided for in the Financial Restructuring Plan, the Group would benefit from a balance sheet with a level of gross financial debt reduced from approximately \$2.9 billon to approximately \$1.2 billion. The maturities of the new notes would be as follows: The net debt / EBITDA ratio (leverage ratio) would be, immediately after completion of the transactions contemplated in the draft safeguard plan, close to 2.1x, while it would have reached almost 8.5x in the absence of any financial restructuring. The impacts of the Financial Restructuring Plan on the Group's liquidity are as follows: - the implementation of the Financial Restructuring Plan is reflected, if cumulated, over the period of 2017-2019 by net savings of financial costs in cash (after interests payments, and principal repayments) of approximately \$225 million, after considering the costs related to the restructuring (fees of attorneys, banks, advisers, experts..) and given the tax advantages related to the safeguard proceedings; - the Group would have an increase of its cash flows close to \$300 million immediately after the implementation of the restructuring, corresponding to the residual products (i) of the Rights Issue with PSR and (ii) of the issuance of the New Second Lien Notes, after payment of the various compensations of placement and backstop and partial repayment of the Secured Loans; - the Group would have a capacity to raise new secured debt in the future, pari passu with the new first lien notes up to an amount of \$200 million, the

lenders having accepted to share their securities and guarantees up to a maximum amount of \$900 million. After the restructuring, the amount of new first lien notes would reach \$677 million.
Number of securities issued
The Company will notify the market of the precise date of the launch of the Rights Issue with PSR, for which a prospectus will be submitted to the AMF for its approval (visa), and of the date of settlement and delivery of the different issuances. The settlement and delivery of all the issuances of Warrants #1, Warrants #3, Creditor Shares 1, Creditor Shares 2, Coordination Warrants, and Backstop Warrants will occur concomitantly with the settlement and delivery of the issue, with shareholders' preferential subscription rights, of new shares with warrants, subject to satisfaction of all the above-mentioned conditions precedent. The issuances provided for under the draft safeguard plan and the Chapter 11 plan shall be regarded as a whole; if one of them could not be implemented, none of them would be implemented.
The Company will notify the market of the final number of shares to be issued under issues reserved for creditors, after the centralization period of the Rights Issue with PSR.
Governance
Subject to the vote of the Company's general meeting of shareholders, the structure and composition of the Company's Board of Directors after the restructuring will be determined in consultation with DNCA and the members of the ad hoc committee of Senior Notes holders who will have become and remained shareholders of the Company.

The structure and composition of the board of directors will have to comply with the AFEP-MEDEF Code and will be put in place promptly and in any event no later than three months after the Restructuring Effective Date.

Challenge of the draft safeguard plan by certain Convertible Bonds holders

On August 4, 2017, certain holders of Convertible Bonds (Keren Finance, Delta Alternative Management, Schelcher Prince Gestion, Financière de l'Europe, Ellipsis Asset Management and HMG Finance) filed an appeal against the draft safeguard plan adopted by the committee of banks and assimilated creditors, and the sole general meeting of bondholders on July 28, 2017, which will be examined during the hearing on the draft safeguard plan, scheduled for November 6, 2017.

Without disputing the results of the general meeting of bondholders' vote, these holders of Convertible Bonds challenge the treatment of their claims under the draft safeguard plan, arguing that the differences in treatment between the Convertible Bond holders and the Senior Notes holders is not justified by the differences in their situations and would be, in any event, disproportionate.

The Company considers that the holders of Convertible Bonds are not in the

		same situation as the Senior Notes holders, in particular regarding the guarantees given to the latter, so that the differentiated treatment provided for in the draft safeguard plan is compliant with legal provisions.
		Should this claim be declared well founded by the Court, the Court may not adopt the draft safeguard plan in so far as it does not have the power to modify its terms.
		If the action was declared groundless and the draft safeguard plan is sanctioned by the Court, the Convertible Bonds holders might appeal this judgment, which will, nevertheless, remain fully enforceable on a provisional basis (the implementation of the safeguard plan would not be suspended), except in the event of (i) an appeal from the public Prosecutor's office (Parquet) or (ii) the suspension of the provisory enforcement pronounced by the first president of the Paris Court of Appeal, by a summary proceedings (en référé) at French Commercial Code, and provided that the grounds relied on in support of the appeal appear serious.		the request of the claimants, pursuant to article R.		661-1 of the
		If such a request were granted, the implementation of the Financial Restructuring Plan would be delayed or jeopardized. Although the Company believes that the occurrence of this risk of suspension of the provisional enforceability of the judgment sanctioning the plan prior to the implementation of the Financial Restructuring Plan is unlikely, it cannot be completely ruled out. Furthermore, following the implementation of the Financial Restructuring Plan, the draft safeguard plan could be canceled with retroactive effect if the Court of Appeal accepted the claimants' requests. Such a cancellation could theoretically have the effect of invalidating the financial restructuring of the CGG group.

B.8	Pro forma financial information	Not applicable.
B.9	Projected or estimated income	These forward-looking statements are given for the year 2017. They are based on the consolidated financial statements for the fiscal year ended December 31, 2016 and on the consolidated financial statements as of June 30, 2017 and are established in accordance with IFRS and accounting methods applied by the Group. They are part of a context in which (i) the Group's management remains heavily dependent on the evolution in the oil and oil-related market, which is particularly difficult to anticipate, and (ii) the Group has set up a draft safeguard plan for CGG and a "Chapter 11" plan for 14 of the Group's foreign subsidiaries, in order to restructure its financial debt. Subject to the required approvals from the shareholders, the Commercial Court of Paris and the US Courts, the financial restructuring should be effective early 2018. CGG disclosed its outlook for the fiscal year 2017 on March 3, 2017 and confirmed them when it published its results for the first quarter on May 12, 2017 and its results for the second quarter on July 28, 2017. This outlook consists of a view of its EBITDAS excluding restructuring costs related to the Transformation Plan similar to that of 2016 for a less favorable cash generation.
B.1 0	Concerns and observtions on the historical financial information	Concerning the first half of 2017 The statutory auditors' report on the first-half of 2017 consolidated financial statements contains the following observations: "Without calling into question the opinion expressed above, we draw your attention to the following: - Note 1.3 "Continuity of operations" in the appendix to the condensed half-year consolidated financial statements, which states that on June 14, 2017, a safeguard procedure was initiated for CGG SA, the parent company of the CGG Group, and a Chapter 11 procedure was initiated in the United States with respect to 14 of its subsidiaries guaranteeing the secured debt and / or high yield bonds; that the Group liquidity as of June 30, 2017 does not allow to fully fund all the current operations until at least June 30, 2018; and that the Group's ability to ensure its continuity of operations depends essentially on the effective and timely implementation of the financial restructuring plan. These factors indicate the existence of significant uncertainties that could call into question the continuity of operations.

- Note 1 "Accounting Principles" in the appendix to the condensed half-year consolidated financial statements, which states that the consolidated financial statements for the year 2016 are still not approved by the shareholders' meeting which will be held later in the year."
Concerning the fiscal year ended December 31, 2016
The statutory auditors' report on the 2016 consolidated financial statements contains the following observations:
"Without disputing the opinion expressed above, we would like to draw your attention on the following:
- note 1.3 "Continuity of operations" to the consolidated financial statements, which states that the Group is confronted in its business with material uncertainties which may raise questions as to its ability to maintain the continuity of operations;
After analysis of the situation and of the operation and cash flow forecasts for the year 2017, the 2016 financial statements have been adopted by the board of directors on a going concern basis.
- notes 1.3 "Continuity of operations" and 13 "Indebtedness" to the consolidated financial statements, which states that in the event of the Group's failure to comply in the future with certain financial covenants ratios and with the corresponding restrictions affecting the funds available under the revolving credit facilities, the term loan B and the Nordic Loan, the acceleration of almost all of the debts should be anticipated, and CGG SA would then be unable to meet its accelerated repayment obligations with its available cash, or to rapidly raise the required additional funds;
As regards this situation, CGG SA requested and obtained the disapplication of the financial covenants before the quarterly terms of December 31, 2016 and March 31, 2017. To this end, the secured lenders of CGG Group unconditionally and irrevocably accepted not to test the financial leverage ratio and the interest coverage ratio at both these dates.
Note 13 indicates that such agreements with the lenders are permanent amendments of the loan agreements and are neither temporary or conditional waivers to test the ratios, nor a grace period. Considering the progress of the negotiations of the financial restructuring of the company and the timeline of the options contemplated, it appears that reclassifying the financial debt as a current liability is the most appropriate accounting treatment according to IAS 1 for the financial statements authorized for issue by the Board of Directors of April 27, 2017. This pure accounting reclassification does not question the going concern assumption, comforted by the main actions plans successfully implemented as of April 27, 2017 and does not make immediately payable (CGG never breached its financial covenants) the US\$2,682.0 million of finance debt classified as current liability nor does it reduce

		their maturity below 12 months.
		- note 1.1 "Critical accounting policies" to the consolidated financial statements, which describes how depreciation and amortization rules were adapted subsequent to the amendment of IAS 16 and IAS 38 "Clarification of acceptable methods of depreciation and amortization" and the impact in the consolidated financial statements for the fiscal year."
B.1 1	Net working capital	As of the date of this Prospectus, the Group does not have sufficient consolidated net working capital to meet its needs to comply with its obligations over the next twelve months.
		As of September 30, 2017, the Group has liquidity of \$334 million. According to the forecasted cash flows of the Group, in the event that :
		(i) the Company would remain under the safeguard proceedings in France and its 14 subsidiaries under "Chapter 11" in the United States,
		(ii) such situation would not have commercial consequences,
		(iii) no liquidity injection would be completed,
		and given, notably, operational and financial costs of restructuring close to \$90 million, the amount of the deficiency of the working capital for the next 12 months, compared to the level required to enable the good implementation of the operations, would be between \$25 and \$50 million. Furthermore, the Group considers that if the Financial Restructuring Plan were not implemented as described in paragraph B.4a, it would be exposed to adverse commercial consequences, with clients demonstrating their strong reluctance to commit (on projects of pre-financing of multi-clients projects for example), consequences that could lead to increase the deficiency of the working capital within 12 months by an amount in the range of \$100-150 million.
		However, if the various financial restructuring transactions described in this summary are completed (including the Rights Issue with PSR with respect to which a prospectus will be submitted to the AMF for approval (visa)), the Company certifies that, from its point of view, its net working capital would be sufficient to meet its obligations for the twelve months following the date of the Prospectus.

The share capital reduction through diminution of share par value to one euro cent (€0.01) will be submitted for approval to the Company's general meeting of shareholders scheduled to convene on October 31 2017. It should be noted that: (i) the nominal value of the issue of Creditor Shares 2 and the number of Creditor Shares 2 to be issued, will be determined on the basis of (a) the total aggregate amount of principal and accrued unpaid interest outstanding on the Senior Notes as of the Reference Date, and (b) the portion of the Rights Issue with PSR which the holders of Senior Notes actually subscribe for by way of set-off against their claim under the Senior Notes, as part of their backstop commitment; (ii) the nominal value of the issue of Creditor Shares 1 and the number of Creditor Shares 1 to be issued will be determined based on the aggregate of principal and accrued unpaid interest on the Convertible Bonds as of the Reference Date; (iii) the number of Warrants #3 to be issued and the number of new shares for which they may be exercised, the number of Coordination Warrants to be issued and the number of new shares for which they may be exercised and the number of Backstop Warrants to be issued and the number of new shares for which they may be exercised, will be determined based on the number of Creditor Shares 1 and Creditor Shares 2 issued, and of the Rights Issue with PSR. A press release will be issued by the Company as soon as possible after the centralization period of the Rights Issue with PSR, with the detailed final information on the number of securities issued.

	unpaid interests) outstanding on the Convertible Bonds as of the same date (after taking into account in the calculation the cash payment for €4.46 million, as described in paragraph B.4a of the summary), rounded down to the nearest whole number of Creditor Shares 1. Only whole numbers of Creditor Shares 1 will be delivered to the holders of Convertible Bonds.
	The total number of Creditor Shares 2 allocated to each holder of Senior Notes shall be determined on the basis of their total claims against the Company relating to the Senior Notes on the Reference Date, compared to the total aggregate amount (principal and accrued and unpaid interests) outstanding on the Senior Notes as of the same date (after taking into account in the calculation the payment of \$86 million, as described in paragraph B.4a of the summary, and as the case may be, any amount used by the holders of Senior Notes to backstop the Rights Issue with PSR), rounded down to the nearest whole number of Creditor Shares 2. Only whole numbers of Creditor Shares 2 will be delivered to the holders of Senior Notes.
	The total number of Warrants #3 to be granted to subscribers of New Second Lien Notes will be determined in such a manner as to entitle them to subscribe for an aggregate number of new shares not in excess of 16% of share capital after the issue of Creditor Shares 1 and Creditor Shares 2, the Rights Issue with PSR, the exercise of the Coordination Warrants, the Backstop Warrants, and the Warrants #3, but before the exercise of the Warrants #1 and the Warrants #2 (the "Diluted Number of Shares"), for a subscription price of 0.01 euro.

−		risk stemming from the absence of implementation of the share capital reduction submitted to the Company's general meeting of shareholders scheduled to convene on October 31, 2017;

Independent expert assessment

The Company's Board of Directors has appointed Ledouble SAS to act as an independent expert in accordance with applicable law for the purpose of assessing the fairness of the restructuring transactions to the Company's shareholders.

The expert's conclusions are set forth below.
"Following our work on valuing CGG shares and reviewing the financial terms and conditions of the Transaction, based on the assumption that the CGG Group continues as a going concern in its current structure, we believe the salient points for the Shareholders are as follows:
The Transaction, which will equitize more than €1.8 billion of debt, meets an immediate need to reduce the Group's indebtedness, which is essential if it is to continue as a going concern. The Group's continuation as a going concern is contingent on:  A recovery in business and an improvement in margins, in accordance with Management's Business Plan forecasts; and  At least a partial refinancing in the future to meet payments falling due with respect to the non-equitized Secured Debt and the unsubordinated second lien New Second Lien Notes to be issued. As regards the value range resulting from our valuation and the subordination of Shareholders ranking them after the Creditors, it appears that the Shareholders would have potentially lose their entire investment without a financial restructuring which is essential
to the continuity of the Group's operations. The subscription prices of €3.12 and €10.26 for the Reserved Capital Increases for the Creditors, respectively the Senior Noteholders and the CB holders, show a premium over our multi criteria valuation of CGG.
The \$375 million issue of high-yield New Second Lien Notes governed by the laws of New York State will be accompanied by the allotment of three classes of Warrants with an exercise price of €0.01, exercise of which will increase the dilution of CGG Shareholders. All of the impacts of these New Second Lien Notes are included in our analysis of the Shareholders' position.
Based on the CGG valuation range, our analysis of the Shareholders' interest, pre- and post-Restructuring, shows that:  The Shareholders will not lose value based on the valuations of CGG that include a Business Plan execution risk, which lead to negative pre-Restructuring equity values;  A valuation based on share price as of May 11, 2017 could result in a loss of up to 60% for the Shareholders due to the high share price relative to CGG's intrinsic value.
The Rights Issue with PSR, at a subscription price of €1.56, shows a discount to the multi-criteria valuation of CGG based on Management's Business Plan; the discount disappears if we assume a delay in achieving the Business Plan forecasts. Shareholders not wishing to subscribe to the offering will be able to sell their Rights. Shareholders will receive Warrants that, albeit out of the money at present and therefore excluded from our analysis, have a long exercise period.
In view of the current situation and the intrinsic value of the Group, we

are of the opinion that the Transaction taken as a whole is fair to CGG Shareholders. "
The independent expert's opinion is reproduced in its entirety in Schedule 1 to this Securities Note.
Suspension of the right of holders of Convertible Bonds to convert them into shares
As part of the Company's financial restructuring, the holders of Convertible Bonds are expected to subscribe for the Creditor Shares 1 by way of set-off against their claims against CGG relating to the Convertible Bonds.
The right of holders of Convertible Bonds to convert them into shares will be suspended, according to the indicative timetable, from November 28, 2017 (at 12 a.m. Paris time), to no later than February 28, 2018 (at 11.59 p.m. Paris time) as prescribed by law and regulations and in accordance with the terms and conditions of the Convertible Bonds, with the understanding that, on that date, if the financial restructuring is completed, there will no longer be any Convertible Bonds outstanding (as the claims of their holders will have been set off by the subscription for the Creditor Shares 1).
