As part of the Offer, each Songa Offshore shareholder may instead elect to receive an amount in cash of NOK 47.50 per Songa Share up to a maximum of NOK 125,000 per shareholder (the “Cash Election”) in lieu of some or all of the Consideration Shares and Exchangeable Bonds such shareholder would otherwise be entitled to receive in the Offer. The aggregate amount of Consideration paid to each Songa Offshore shareholder accepting the Offer shall be comprised, as near as possible, of 50% Consideration Shares and 50% Exchangeable Bonds, with any exercise by such shareholder of the Cash Election, if elected, being deducted first from the aggregate number of Exchangeable Bonds otherwise issuable to such shareholder and then from the aggregate number of Consideration Shares such shareholder would otherwise be entitled to receive in the Offer.

Songa Offshore shareholders may tender Songa Shares that are issued and delivered after the expiration of the offer period as a result of exercise of Songa Offshore warrants or restricted share units, or conversion of Songa Offshore convertible bonds, provided that such Songa Shares are issued prior to settlement of the Offer.

In connection with the Combination, our board of directors (the “Transocean Board”) is asking shareholders to approve the following matters at an extraordinary general meeting of shareholders to be held on [], 2017 at [], Swiss time, at [], Switzerland (the “Extraordinary General Meeting”):

the amendment to our Articles of Association to create additional authorized share capital for purposes of effecting any mandatory offer for, or compulsory acquisition (squeeze-out) of, the remaining Songa Shares not owned by Transocean immediately after completion of the Offer;

the election of one new director to the Transocean Board for a term extending until completion of the next annual general meeting; and

You should carefully review “Terms of the Offer” and the Transaction Agreement, which contains a more detailed description of the terms and conditions to the Offer.


Issuer of Consideration Shares	Transocean Ltd.
Issuer of Exchangeable Bonds	TINC
Target	Songa Offshore SE

Subject Matter of the Offer

Transocean Ltd. seeks to acquire each of the issued and outstanding Songa Shares (on a fully diluted basis).

Consideration

For each Songa Share validly tendered in the Offer and not properly withdrawn, the Consideration will consist of a combination of the following:

	1. 0.35724 Consideration Shares; and
	2. USD 2.99726 principal amount of the Exchangeable Bonds.

As part of the Offer, each Songa Offshore shareholder may instead elect the Cash Election in lieu of some or all of the Consideration Shares and Exchangeable Bonds such shareholder would otherwise be entitled to receive in the Offer. The value of any cash and the value of the aggregate number of Consideration Shares and Exchangeable Bonds to be delivered per Songa Share is the “Offer Price.”

Transocean will not issue any fractional Consideration Shares or fractional amounts of Exchangeable Bonds in the Offer. Each Songa Offshore shareholder who accepts the Offer and, following the completion of the Offer, any Songa Offshore shareholder in connection with a subsequent mandatory offer or compulsory acquisition (squeeze-out) (a) who would otherwise be entitled to receive a fraction of a Consideration Share will instead receive, for the fraction of a Consideration Share, an amount in cash based on USD 8.39, the closing price of the Consideration Shares on the NYSE on August 14, 2017, the last trading day prior to the announcement of the proposed Combination and Offer (the “Reference Price”), and (b) who would otherwise be entitled to receive a fractional amount of Exchangeable Bonds will instead receive, for the fractional amount of Exchangeable Bonds, an amount in cash based on USD 1,000, the principal amount per Exchangeable Bond, and in each case, paid in NOK, based on an exchange rate of 7.923 NOK per U.S. dollar which is the NOK/USD closing price at 4:00 p.m. CET as determined by Norges Bank, on August 14, 2017, the trading day immediately preceding the announcement of the Offer.

Adjustments to the Consideration

The number of Consideration Shares and Exchangeable Bonds shall each be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend and other like change (including any dividend or distribution of securities exchangeable into Consideration Shares or Songa Shares), in accordance with the procedures set out in “Terms of the Offer—Amendments to the Offer.” If an adjustment is made, acceptances of the Offer received prior to such adjustment shall be deemed an acceptance of the Offer as revised.

Table of Contents

Higher Consideration

Under the terms of the Offer, Transocean Ltd. (the “Offeror”) and any entity wholly owned directly or indirectly by Transocean shall not directly or indirectly acquire or enter into any agreement to acquire Songa Shares (in the open market or in privately negotiated transactions or otherwise) following announcement of the contemplated Offer until (i) the lapsing or withdrawal of the Offer or (ii) the completion of the Offer as contemplated by this proxy statement or, if relevant, expiration of a subsequent mandatory offer, at a consideration higher than the Offer Price, without increasing the Offer Price for all Songa Shares included in the Offer so as to be at least equal to such higher consideration. Notwithstanding the foregoing, the Offer Price shall not be increased pursuant to the aforementioned as a result of (i) the payment of cash consideration (including the effect of any change in currency exchange rates) in any subsequent mandatory offer in accordance with the minimum Offer Price requirements as decided by the Oslo Stock Exchange, (ii) share price fluctuations during or after the Offer Period, as defined below or (iii) the application of calculation principles by the Oslo Stock Exchange or any other governmental or regulatory authority to any subsequent mandatory offer that differs from the calculation principles specified in the Transaction Agreement.

Conditions for Completion of the Offer

The completion of the Offer is subject to the following conditions, each one of which may be waived by the Offeror fully or partly (at the Offeror’s sole discretion), provided, however, that condition (1) can only be waived to the extent the Offeror has received acceptances for more than 63% of the total share capital of Songa Offshore on a fully diluted basis (and cannot be waived if the Offeror has received acceptances for 63% or less of the total share capital of Songa Offshore on a fully diluted basis), and conditions (2), (6), (7), (8) or (11) can only be waived with the prior written consent of Songa Offshore:

1. Minimum acceptance of more than 90%. On or prior to the expiration of the Offer Period, Songa Offshore shareholders shall in the aggregate have accepted the Offer subject to the terms and conditions of the Offer for a number of Songa Shares representing more than 90% of the total share capital of Songa Offshore, on a fully diluted basis (i.e. calculated based on the assumption that any and all outstanding warrants, convertible bonds and other securities convertible into or otherwise giving rights to new Songa Shares have been exercised in full regardless of the conditions for such exercise), and the same amount of votes, which can be exercised in the general meeting of Songa Offshore, and such acceptances shall remain valid and binding.


	2. Governmental and regulatory approvals. Any governmental, regulatory or other official approval and/or clearance, under any applicable laws or regulations, which are necessary for the completion of the Offer and the transactions contemplated hereunder, shall have been duly obtained without any conditions, unless such conditions are clearly insignificant in the context of (i) Transocean’s existing business operations in Norway or (ii) the expected benefits to Transocean of the acquisition of Songa Offshore.

Table of Contents

3. No intervention. No court or other governmental or regulatory authority of competent jurisdiction shall have taken any form of legal action (whether temporary, preliminary, or permanent) that restrains or prohibits the completion of the Offer or shall in connection with the Offer have imposed conditions upon Transocean, Songa Offshore or any of their respective subsidiaries, that Transocean in its sole discretion determines to be unduly burdensome.

In the period from the announcement of the contemplated Offer until the settlement of the Offer there shall have been no changes or decisions to make changes to the share capital of Songa Offshore or its subsidiaries other than issuances of shares as required by the exercise of warrants or options or the conversion of convertible bonds and/or exercise of any other Songa Offshore securities, which are made in accordance with the terms of such agreements (which have been provided to Transocean prior to the entering into of the Transaction Agreement or the terms of which are otherwise publicly available) underlying such warrants, options, convertible bonds and/or other Songa Offshore securities and no issue or decision to issue any rights which entitle the holder to any form of equity interest in Songa Offshore or its subsidiaries, and Songa Offshore shall not have declared or made any dividends or other forms of distributions, in each case from the date of announcement of the contemplated Offer.

Offer Period

The shareholders of Songa Offshore may accept the Offer in the period from and including [], 2017 to and including [], 2017 at 4:30 p.m. (CET) (as extended from time to time, the “Offer Period”). Transocean may in its sole discretion, and subject to approval from the Oslo Stock Exchange, extend the Offer Period (one or more times), however not beyond [], 2018 at 4:30 p.m. (CET) Any extensions of the Offer Period will be announced prior to the expiration of the Offer Period. When referring to the Offer Period in this proxy statement, this refers to the Offer Period as extended from time to time. If the Offer Period is extended, the other dates referred to herein may be changed accordingly and any received acceptance forms (“Acceptance Forms”) will remain binding for the length of the extension. Except as prohibited by the Transaction Agreement and applicable law, Transocean may, at its sole discretion and at any time, decide to cancel the Offer.

Long Stop Date

If the Offer has not become unconditional by January 31, 2018 at 4:30 p.m. (CET) (the “Long Stop Date”), the Offer shall lapse and any tendered shares shall be released by Transocean, provided, however, that the Long Stop Date may be extended at the election of Transocean one time for no more than a total of 25 U.S. business days to the extent deemed necessary, at Transocean’s sole discretion, for the purpose of soliciting additional proxies from shareholders for the election at the Extraordinary General Meeting of the Perestroika Designee. With respect to any extension by Transocean, Transocean will, prior to such extension, publicly confirm the fulfilment of all other conditions for completion of the Offer (other than conditions (3), (4) and (9) in “—Conditions for Completion of the Offer”). However, with respect to condition (10) under “—Conditions for Completion of the Offer,” if a willful breach by Songa Offshore of any agreement or covenant in the Transaction Agreement occurs solely on or after the Long Stop Date, then condition (10) shall not be satisfied and, in such event, Transocean reserves all of its rights with respect thereto (including completion of the Offer) to determine the satisfaction or waiver of such condition.

Transocean’s Reasons for the Combination (see page [])

At a meeting held on August 11, 2017, after due consideration and consultation, the Transocean Board unanimously approved (i) the total consideration of NOK 47.50 per Songa Share and (ii) the Combination and the transactions contemplated thereby. In reaching its determination, the Transocean Board considered a number of factors in connection with its evaluation of the proposed transaction, including significant strategic opportunities and potential synergies, as generally supporting its decision to enter into the Transaction Agreement and proceed with the transactions contemplated thereby. See “The Combination—Background and Reasons for the Combination—Transocean’s Reasons for the Combination” for a discussion of the factors considered by the Transocean Board.

Songa Offshore’s Reasons for the Combination

The Songa Board (with the exception of Songa Offshore directors Mr. Mohn and Mr. Mikkelsen, who were excused from voting on whether to approve the Transaction Agreement) unanimously determined to enter into the Transaction

Table of Contents

Agreement and recommend that Songa Offshore’s shareholders accept the Offer. In addition to consulting with Songa Offshore management and its financial and legal advisors, the Songa Board considered a number of factors when evaluating the transaction. See “The Combination—Background and Reasons for the Combination—Songa Offshore’s Reasons for the Combination” for a discussion of the factors considered by the Songa Board.

The Transaction Agreement (see page [])

The terms and conditions of the Combination are contained in the Transaction Agreement, which is attached as Annex B and incorporated into this proxy statement by reference. Transocean urges you to read the full text of the Transaction Agreement because it is the legal document between Transocean and Songa Offshore that governs the Combination.

Material Interests of Songa Offshore’s Board and Management in the Combination (see page [])

Some of the members of the Songa Offshore board of directors (the “Songa Board”) and the Songa Offshore executive officers may have interests in the Combination that are different from, or in addition to, the interests of the Songa Offshore shareholders. These interests may include, but are not limited to, the treatment of restricted share units or other equity instruments owned by certain Songa Offshore executive officers under Songa Offshore’s long-term incentive plan (the “Songa Offshore Long-Term Incentive Plan”), or cash severance and other benefits under change in control arrangements. Additionally, Songa Offshore’s executive officers are expected to continue their employment with the combined company under the terms of their current employment agreements following the closing of the Combination through December 31, 2017. These interests also include Transocean’s agreement to nominate the Perestroika Designee, as defined in “Agenda Item 3,” to the Transocean Board (subject to the election of Frederik W. Mohn, the Chairman of the Songa Board, as the Perestroika Designee at the Extraordinary General Meeting pursuant to Agenda Item 3 described in this proxy statement). As of August 14, 2017, members of the Songa Board and the Songa Offshore executive officers and their affiliates, excluding Perestroika AS (“Perestroika”), owned 361,160 Songa Shares in the aggregate, representing 0.3 percent of the issued Songa Shares. In addition, the Perestroika Designee is the sole owner of Perestroika, Songa Offshore’s largest shareholder. As of October 31, 2017, Perestroika held 59,489,590 Songa Shares and SONG07 convertible bonds convertible into 27,556,518 Songa Shares. Perestroika also holds approximately NOK 330 million principal amount of SONG04 bonds issued by Songa Offshore that will be purchased by Transocean at a price of 103.5% and a USD 50 million loan to Songa Offshore that will be purchased by Transocean at a price of 100%, each in connection with the completion and settlement of the Offer. See “Terms of the Offer—Refinancing of Certain Songa Offshore Indebtedness.”

None of the members of the Transocean Board or Transocean’s executive officers owns any Songa Shares or other securities exchangeable or convertible into Songa Shares.

Material Tax Considerations of the Combination (see page [])

Transocean should not incur additional U.S. federal income tax solely by virtue of the consummation of the Combination.

Information Regarding our Executive Compensation Program

We are seeking the election by shareholders of one director. The rules of the U.S. Securities and Exchange Commission (“SEC”) require us to provide compensation information for the last completed year for this voting item, even though we previously presented the same information in connection with our 2017 Annual General Meeting. For additional information, see the sections of this proxy statement titled “Transocean Corporate Governance,” “Transocean Board” and “Executive Officers—Transocean Board,” “Board Meetings and Committees,” “2016 Director Compensation,” “Compensation Discussion and Analysis,” “Executive Compensation” and “Equity Compensation Plan Information.” All compensation related items were approved at our 2017 Annual General Meeting. Accordingly, we will not seek your vote for any compensation related items at this Extraordinary General Meeting.

In 2015, Transocean allowed shareholders to receive dividends in Swiss francs or U.S. dollars.

Dividends

Transocean

All shares in Transocean have equal rights to dividends. The holders of Transocean shares are entitled to receive dividends as are lawfully declared on Transocean shares by a general meeting of Transocean’s shareholders. No cash dividends were paid on Transocean shares during the first nine months of 2017 or during fiscal years 2016 and 2015. Transocean’s ability to pay future cash dividends will (a) depend on our results of operations, financial condition, cash requirements and other relevant factors, (b) be subject to shareholder approval, (c) be subject to restrictions contained in our credit facilities and other debt covenants, (d) be affected by our plans regarding share repurchases or noncash shareholder distributions and (e) be subject to restrictions imposed by Swiss law, including the requirement that sufficient distributable profits from the previous year or freely distributable reserves must exist. Transocean does not expect to pay cash dividends in the foreseeable future.

Table of Contents

Songa Offshore

All Songa Shares have equal rights to dividends. Pursuant to Regulation 112 of Songa Offshore’s memorandum of association and articles of association (“Songa’s Articles of Association”), and provided that Songa Offshore has sufficient distributable profits, Songa Offshore may, at a general meeting of its shareholders, declare by ordinary resolution (simple majority) dividends to be paid out of profits and to be distributed to the shareholders pro rata based on their holdings in Songa Offshore but no dividend will exceed the amount recommended by the Songa Board. The Songa Board may declare interim dividends as appear to the Songa Board to be justified by the profits of Songa Offshore (Regulation 113 of Songa’s Articles of Association). Songa Offshore’s current ability to pay dividends is restricted by contractual arrangements including restrictions under its different loan agreements. Over time, when and as Songa Offshore has adequate financial resources, declaration of dividends will be considered by the Songa Board. Songa Offshore has not paid any dividends for any of the years from 2010 to 2016.

Recent and Comparative Market Price Information

The following table sets forth the closing sale price per Transocean share and Songa Share as reported on the NYSE and the Oslo Stock Exchange, respectively, as of August 14, 2017, the last trading day before the public announcement of the contemplated Combination, and as of November 24, 2017, the most recent practicable trading day prior to the date of this proxy statement. The table also shows the implied value of the consideration proposed for each Songa Share as of the same dates which amounts are calculated by multiplying the closing sales prices for shares of Transocean shares by 0.7145, representing the approximate per share value of the Consideration that a Songa Offshore shareholder will be entitled to receive as of such dates, in exchange for each Songa Share they hold at the effective time of the Combination.

The market prices of shares of Transocean and Songa Offshore fluctuate, and the value of the Consideration will fluctuate with the market price of the Transocean shares. No assurance can be given concerning the market prices of Transocean shares and Songa Shares before the completion of the Combination or Transocean shares after the completion of the Offer. Because the exchange ratio is fixed in the Transaction Agreement, the market value of the Transocean shares that Songa Offshore shareholders will receive in connection with the Combination may vary significantly from the prices shown in the table below. Accordingly, you are urged to obtain current market quotations of Transocean shares and Songa Shares before making any decision with respect to the proposals in this proxy statement.

INFORMATION ABOUT THE EXTRAORDINARY GENERAL MEETING AND VOTING

This proxy statement is furnished in connection with the solicitation of proxies by Transocean, on behalf of its Transocean Board, to be voted at our Extraordinary General Meeting to be held on [], 2017 at [], Swiss time, at [], Switzerland.

On August 13, 2017, Transocean entered into the Transaction Agreement with Songa Offshore pursuant to which we are offering to acquire all of the issued and outstanding Songa Shares (on a fully diluted basis) through a voluntary tender offer in exchange for consideration per Songa Share consisting of (i) 0.35724 newly issued shares of Transocean, par value CHF 0.10 per share, and (ii) USD 2.99726 principal amount of 0.5% Exchangeable Senior Bonds due 2022, which are exchangeable into shares of Transocean, par value CHF 0.10 per share, to be issued by TINC. As part of the Offer, each Songa Offshore shareholder may instead elect to receive an amount in cash of NOK 47.50 per Songa Share up to a maximum of NOK 125,000 per shareholder in lieu of some or all of the Consideration Shares and Exchangeable Bonds such shareholder would otherwise be entitled to receive in the Offer. The aggregate consideration paid to each Songa Offshore shareholder accepting the Offer shall be comprised, as near as possible, of 50% Consideration Shares and 50% Exchangeable Bonds, with any exercise by such shareholder of the Cash Election, if elected, being deducted first from the aggregate number of Exchangeable Bonds otherwise issuable to such shareholder and then from the aggregate number of Consideration Shares such shareholder would otherwise be entitled to receive in the Offer.

If the Offer is completed and we acquire Songa Shares representing 90% or more of the voting rights in Songa Offshore, we intend to initiate a compulsory acquisition (squeeze-out) of the remaining Songa Shares not owned by Transocean pursuant to article 36 of the Cyprus Takeover Bids Law (L.41(I)/2007), as amended, as soon as practicable following the completion of the Offer. A compulsory acquisition can be expected to be completed after 35 working days from completion of the Offer, provided that the required application is submitted to the Cyprus Securities and Exchange Commission immediately after completion and that the Cyprus Securities and Exchange Commission will make its decision on the application within 10 working days from its submission. However, this is only an estimate as the process to complete a compulsory acquisition may be delayed due to several factors beyond the control of the Company. The Cyprus Securities and Exchange Commission is not subject to a time limit in deciding whether to approve an application to complete a compulsory acquisition, and no assurances can be given as to the exact duration of the compulsory acquisition process.

We cannot complete the Combination unless each of Agenda Items described in this proxy statement is approved by our shareholders.

Record Date

Only shareholders of record on [], 2017 are entitled to notice of, to attend, and to vote or to grant proxies to vote at, the Extraordinary General Meeting. No shareholder will be entered in Transocean’s share register with voting rights between the close of business on [], 2017 and the opening of business on the day following the Extraordinary General Meeting.

While no shareholder will be entered in Transocean’s share register as a shareholder with voting rights between the close of business on [], 2017 and the opening of business on the day following the Extraordinary General Meeting, share blocking and re-registration are not requirements for any Transocean shares to be voted at the meeting, and all shares may be traded after the record date. Computershare, which maintains Transocean’s share register, will continue to register transfers of Transocean shares in the share register in its capacity as transfer agent during this period.

Quorum

Transocean’s Articles of Association provide that the presence of shareholders, in person or by proxy, holding at least a majority of all the shares entitled to vote at the meeting constitutes a quorum for purposes of convening this Extraordinary General Meeting and voting on all of the matters described in the notice of meeting. Abstentions will be counted as present for purposes of determining whether there is a quorum at the meeting. None of the matters to be

considered at the Extraordinary General Meeting are “routine” matters under NYSE rules, so brokers are not entitled to vote at the Extraordinary General Meeting unless instructed to do so by the beneficial owner of the shares, and shares for which brokers do not receive voting instructions will not be counted for purposes of determining whether there is a quorum present.

Votes Required

The following table sets forth the applicable vote standard required to pass each enumerated Agenda Item:

(1)

The affirmative vote of at least two-thirds of the votes and the absolute majority of the par value of shares, each as present or represented at the Extraordinary General Meeting. An abstention or invalid vote will have the effect of a vote “against” this proposal.

(2)

Affirmative vote of a plurality of the votes cast in person or by proxy at the Extraordinary General Meeting. The plurality requirement means that the nominee with the most votes for a board position or the chair is elected. Only votes “for” are counted in determining whether a plurality has been cast in favor of a nominee. Abstentions or invalid votes do not have any effect on the outcome of the vote. As described later in this proxy statement, our Corporate Governance Guidelines set forth our procedures if a nominee is elected but does not receive more votes cast “for” than “against” the nominee’s election.

(3)

Affirmative vote of a majority of the votes cast in person or by proxy at the Extraordinary General Meeting. Abstentions or invalid votes do not have any effect on the outcome of the vote.

Under NYSE rules, brokers who hold shares in “street name” for customers, such that the shares are registered on the books of the Company as being held by the brokers, have the authority to vote on “routine” proposals when they have not received instructions from beneficial owners, but are precluded from exercising their voting discretion with respect to proposals for “non-routine” matters. All of the items on the agenda of the Extraordinary General Meeting are “non-routine” matters under NYSE rules.

If you hold your shares in “street name,” your broker will not be able to vote your shares on the Agenda Items and may not be able to vote your shares on other matters at the Extraordinary General Meeting unless the broker receives appropriate instructions from you. We recommend that you contact your broker to exercise your right to vote your shares.

AGENDA ITEM 1.

ISSUANCE OF THE CONSIDERATION SHARES IN AN ORDINARY SHARE CAPITAL INCREASE

Proposal of the Transocean Board

The Transocean Board proposes that the shareholders approve the ordinary share capital increase relating to the issuance of up to [•] Consideration Shares in an ordinary share capital increase of the Company against contribution-in-kind of a portion of the Songa Shares tendered in the Offer. The consideration for the portion of the Songa Shares not acquired against the issuance of Cosideration Shares will consist of a combination of Exchangeable Bonds issued to holders of Songa Shares tendering in the Offer by TINC, to which the Company issues, as consideration for the issuance of the Exchangeable Bonds, Exchangeable Notes that in amount and terms substantially correspond to those of the Exchangeable Bonds, and Exchangeable Notes issued by the Company to TINC, respectively, and the payment of cash to holders of Songa Shares tendering in the Offer (to the extent a holder of Songa Shares exercises the Cash Election or would otherwise receive a fraction of a Consideration Share or fractional amount of Exchangeable Bonds), all as further described in the shareholders' resolution set forth in Annex A-1. In the ordinary share capital increase, the preferential subscription rights of the Company’s shareholders will be excluded.

Explanation

The Company’s share capital currently consists of 394,801,990 fully paid-in shares, par value CHF 0.10 each. In connection with the Offer, the Company will issue up to [] new shares as Consideration Shares. The definitive number of Consideration Shares will be determined by the Transocean Board by reference to (i) the number of Songa Shares that have been validly tendered to the Offer, as may be reduced by the value of the cash amount paid to holders of Songa Shares tendering in the Offer and whose exercise of the Cash Election results in a reduction of the Consideration Shares otherwise issuable to such holders of Songa Shares, and (ii) an exchange ratio of 0.35724 Consideration Shares for each Songa Share (whereby such holders shall receive cash for any fraction of a Consideration Share resulting from such exchange ratio).

The Consideration Shares will be paid for through a contribution-in-kind of a portion of the Songa Shares tendered in the Offer. The Company will acquire the portion of the Songa Shares not acquired for Consideration Shares through the payment of consideration consisting of (i) up to [●] Exchangeable Bonds to be issued by TINC, to which the Company issues, as consideration for the issuance of the Exchangeable Bonds, up to [●] Exchangeable Notes that in amount and terms substantially correspond to those of the Exchangeable Bonds, and (ii) the payment of up to NOK 125,000 per holder of any Songa Shares who exercises the Cash Election and (iii) the payment of cash based on the Reference Price to holders of Songa Shares tendering in the Offer who as a result of the exchange ratio applicable in the Offer would otherwise receive any fraction of a Consideration Share or fractional amounts of Exchangeable Bonds (all as further described in the shareholders' resolution set forth in Annex A-1). Because the Consideration Shares are paid in through a contribution-in-kind of Songa Shares, the preferential subscription rights of the Company’s shareholders will be excluded.

Approval of the issuance of the Consideration Shares in an ordinary capital increase is a condition to completion of the Offer. The Transocean Board has approved the Combination, including the issuance of the Consideration Shares in the Offer in an ordinary capital increase, and is therefore seeking shareholder approval of the issuance of the Consideration Shares in an ordinary capital increase for the purpose of completing the Combination.

Recommendation

The Transocean Board recommends you vote “FOR” this proposal.

AGENDA ITEM 2.

AMENDMENT TO THE ARTICLES OF ASSOCIATION TO CREATE ADDITIONAL AUTHORIZED SHARE CAPITAL FOR PURPOSES OF EFFECTING A MANDATORY OFFER OR A COMPULSORY ACQUISITION

Proposal of the Transocean Board

The Transocean Board proposes that the Company’s Articles of Association be amended and a new Article 5bis be adopted to authorize the Transocean Board to issue up to [] shares, par value CHF 0.10 each, in connection with a mandatory offer or a compulsory acquisition (if any) of Songa Shares following the completion of the Offer. The proposal is conditional on completion of the Offer. The proposed shareholder resolution and the proposed amendment to the Articles of Association are attached as Annex A‑2.

Explanation

Currently, pursuant to Article 5 of the Articles of Association, the Transocean Board is authorized to increase the share capital, at any time until May 12, 2018, by a maximum amount of CHF 2,225,804.30 by issuing a maximum of 22,258,043 fully paid up shares with a par value of CHF 0.10 each.

In connection with the Offer, Transocean expects to issue up to [] new shares of Transocean as Consideration Shares out of the ordinary share capital increase proposed under “Agenda Item 1.” If not all Songa Shares are tendered in the Offer, the Company may launch a mandatory offer or a compulsory acquisition (if any) following the completion of the Offer in order to acquire 100% of all issued and outstanding Songa Shares. In order for the Transocean Board to have flexibility as regards the timing of any mandatory offer or a compulsory acquisition (if any) that we are required to make following the completion of the Offer, the Transocean Board is proposing to amend the Company’s Articles of Association and include in Article 5bis a new provision according to which the Transocean Board is authorized, during a two-year period after the date of the Extraordinary General Meeting, to increase the share capital by a maximum of CHF [] by issuing a maximum of [] fully paid up shares in connection with a mandatory offer or a compulsory acquisition (if any) following the completion of the Offer.

Approval of this amendment of the Articles of Association to create additional authorized share capital for purposes of effecting a mandatory offer or a compulsory acquisition is a condition to completion of the Offer. The Transocean Board has approved the Combination and is therefore seeking shareholder approval of the amendment for the purpose of completing the Combination.

Recommendation

The Transocean Board recommends you vote “FOR” this proposal.

AGENDA ITEM 3.

ELECTION OF ONE NEW DIRECTOR TO THE TRANSOCEAN BOARD FOR A TERM EXTENDING UNTIL COMPLETION OF THE NEXT ANNUAL GENERAL MEETING

From 2011‑2013 he served as managing director of the worldwide family business Frank Mohn AS, a supplier of pumping systems to the oil and gas industry. Mr. Mohn also currently serves on the board of directors of public companies Dof ASA (OSE: DOF), a Norwegian shipping company, and Fjord 1 (OSE: FJORD), a Norwegian transport company, and private companies Viken Crude AS, Gjettumgrenda AS, Fornebu Sentrum AS, Fornebu Sentrum Utvikling AS and Høvik Stasjonsby AS og KS.

Mr. Mohn received his Bachelor of Science degree from Royal Holloway, University of London in 2001.

The Transocean Board believes that Mr. Mohn’s knowledge of the oil and gas industry and his expertise in finance will aid the Transocean Board in reviewing strategic decisions for the Company.

Under our Articles of Association, the size of the Transocean Board is currently set at a maximum of 11 members. In order to permit the election of Mr. Mohn to the Transocean Board, Mr. Martin McNamara, a current member of the Transocean Board, has conditionally agreed to retire from the Transocean Board to create a vacancy to be filled by Mr. Mohn if Mr. Mohn is elected. Mr. McNamara’s retirement from the Transocean Board is conditioned on (i) approval by our shareholders of all of the proposals presented at the Extraordinary General Meeting and (ii) completion of the Offer.

The election of Mr. Mohn to the Transocean Board is a condition to completion of the Offer. The Transocean Board has approved the Combination and is therefore seeking shareholder approval of the election of Mr. Mohn to the Transocean Board for a term extending until completion of the Company’s next Annual General Meeting.

The Board has concluded that Mr. Mohn should serve on the Transocean Board and has recommended his election.

Voting Requirements to Elect Mr. Mohn

The election of the nominee requires the affirmative vote of a plurality of the votes cast in person or by proxy at the Extraordinary General Meeting. Shareholders are entitled to one vote per share for the nominee to be elected.

We have adopted a majority vote policy in the election of directors as part of our Corporate Governance Guidelines. This policy provides that the Transocean Board may nominate only those candidates for the position of director who have submitted an irrevocable letter of resignation which would be effective upon and only in the event that (a) such nominee fails to receive a sufficient number of votes from shareholders in an uncontested election and (b) the Transocean Board accepts the resignation. If a nominee who has submitted such a letter of resignation does not receive more votes cast “for” than “against” the nominee’s election, the Corporate Governance Committee must promptly review the letter of resignation and recommend to the Transocean Board whether to accept the tendered resignation or reject it. The

Table of Contents

Transocean Board must then act on the Corporate Governance Committee’s recommendation within 90 days following the certification of the shareholder vote. The Transocean Board must promptly disclose its decision regarding whether or not to accept the nominee’s resignation letter in a Form 8‑K furnished to the SEC or other broadly disseminated means of communication. Full details of this policy are set out in our Corporate Governance Guidelines, which are available on our website at www.deepwater.com under “Investor Relations—Governance.”

The Transocean Board has received from Mr. Mohn an executed irrevocable letter of resignation consistent with these guidelines as described above. Such letter of resignation is effective only in the event that (a) such nominee fails to receive a majority of votes cast by shareholders in an uncontested election and (b) the Transocean Board accepts such resignation.

Recommendation

The Transocean Board recommends a vote “FOR” the election of Mr. Mohn as a director.

AGENDA ITEM 4.

ISSUANCE OF THE CONSIDERATION SHARES, TRANSOCEAN SHARES OUT OF AUTHORIZED SHARE CAPITAL AND THE TRANSOCEAN SHARES ISSUABLE UPON EXCHANGE OF THE EXCHANGEABLE BONDS AS REQUIRED BY THE RULES OF THE NYSE

Proposal of the Transocean Board

As required by the rules of the NYSE, the Transocean Board proposes that the shareholders approve the issuance of the Consideration Shares, Transocean shares out of authorized share capital and Transocean shares issuable upon exchange of the Exchangeable Bonds to be issued in the Combination, as well as Transocean shares issuable upon exchange of the Exchangeable Bonds issued in connection with the refinancing of certain Songa Offshore indebtedness as described below. The shareholders’ resolution authorizing the issuance of the Consideration Shares, the Transocean shares out of authorized share capital and the Transocean shares issuable upon exchange of the Exchangeable Bonds is set forth in Annex A-3.

Explanation

In connection with the Combination, the Company will issue approximately [•] new Transocean shares, either in the form of Consideration Shares, out of authorized share capital, or upon the exchange of Exchangeable Bonds, all as further described below:

The issuance of approximately 68.6 million Transocean shares as Consideration Shares in the Offer.

The issuance of approximately USD [•] million aggregate principal amount of Exchangeable Bonds in the Offer, which will be exchangeable into an aggregate of approximately [•] Transocean shares (based on the initial exchange rate of approximately 97.29756 Shares per USD 1,000 principal amount of Exchangeable Bonds).

The issuance of approximately USD [•] million aggregate principal amount of Exchangeable Bonds in connection with the purchase of certain outstanding indebtedness previously issued by Songa Offshore from certain bondholders in exchange for newly issued Exchangeable Bonds, which will be exchangeable into an aggregate of approximately [•] Transocean shares (based on the initial exchange rate of approximately 97.29756 Shares per USD 1,000 principal amount of Exchangeable Bonds). In particular, Transocean agreed to purchase an aggregate of approximately NOK 1.206 billion of Songa Offshore’s outstanding SONG04 Bonds from three bondholders at a price of 103.5% per bond (plus accrued and unpaid interest) and an aggregate of approximately NOK 587.0 million of Songa Offshore’s outstanding SONG05 Bonds from two bondholders at a price of 101% per bond (plus accrued and unpaid interest). Transocean has also agreed to purchase from Perestroika its USD 50 million loan to Songa Offshore for Exchangeable Bonds at a price of 100% of the principal amount of the loan (plus accrued and unpaid interest). All of these purchases are conditioned on and will close at approximately the same time as the settlement of the Offer. Transocean intends to call all remaining SONG04 Bonds and SONG05 Bonds for cash following the completion of the Offer.

Because the amount of Exchangeable Bonds to be issued in connection with the purchase of certain outstanding indebtedness previously issued by Songa Offshore depends on the amount of accrued and unpaid interest on such indebtedness as of the time the purchase occurs, the Company may issue more Exchangeable Bonds than the approximate value listed above. If these purchases were completed of the date hereof, the Company would be required to issue an additional USD [•] million aggregate principal amount of Exchangeable Bonds, which would be exchangeable into an aggregate of approximately [•] Transocean shares (based on the initial exchange rate of approximately 97.29756 Shares per USD 1,000 principal amount of Exchangeable Bonds).

Table of Contents

In addition, the exchange rate of the Exchangeable Bonds can be adjusted upon the occurrence of certain anti-dilution events, tax event or certain fundamental changes such as a change in control of TINC or Transocean. As a result of these terms of the Exchangeable Bonds, we may be required to issue more Transocean shares than the approximations listed above. Any change in the exchange rate of the Exchangeable Bonds as a result of a tax event or a fundamental change would result in an increase in the then-applicable exchange rate of up to 22.5% depending on the remaining time to maturity of the Exchangeable Bonds. Any change in the exchange rate as a result of a change in control would also entitle each holder of the Exchangeable Bonds to receive 101% of the principal amount of Exchangeable Bonds owned by such holder. For illustrative purposes only, if a change of control of TINC or Transocean were to occur as of the date the Exchangeable Bonds were issued, holders thereof would receive approximately an additional [•] Transocean shares upon conversion of their Exchangeable Bonds.

Under the rules of the NYSE, shareholder approval must be obtained for the issuance of shares in excess of 20% of the number of shares issued and outstanding. The maximum total number of shares that may be issued in connection with the Combination represents approximately [•]% of the Transocean shares currently issued and outstanding.

Other than as described in “Agenda Item 1” and “Agenda Item 2,” there is no Swiss law requirement for any additional shareholder approval of the issuance of the Consideration Shares or any other Transocean shares in connection with the Combination. In particular, Transocean shares issuable upon exchange of Exchangeable Bonds would be issued out of Transocean’s existing conditional share capital.

Approval of the issuance of the Consideration Shares, Transocean shares out of authorized share capital and the Transocean shares issuable upon exchange of the Exchangeable Bonds issued in the Combination and the transactions above is a condition to completion of the Offer. The Transocean Board has approved the Combination, including the issuance of the Consideration Shares, Transocean shares out of authorized share capital and the Transocean shares issuable upon exchange of the Exchangeable Bonds issued in the Combination and the purchases of Songa Offshore indebtedness described above and is therefore seeking shareholder approval of the issuance of the Consideration Shares, Transocean shares out of authorized share capital and the Transocean shares issuable upon exchange of these Exchangeable Bonds.

Recommendation

The Transocean Board recommends you vote “FOR” this proposal.

RISK FACTORS

Risks Related to the Offer

The Offer is subject to conditions and the Transaction Agreement may be terminated in accordance with its terms and the Combination may not be completed.

The Offer is subject to numerous conditions, including inter alia the conditions related to the minimum number of Songa Shares that must be validly tendered (and not subsequently validly withdrawn as of the end of the Offer Period), the receipt of regulatory approvals and the absence of material adverse changes with respect to Songa Offshore. See “Terms of the Offer—Conditions for Completion of the Offer.” No assurance can be given that all of the conditions to the Offer will be satisfied or, if they are, as to the timing of such satisfaction. If the Offer has not become or been declared unconditional before 11:59 p.m. (CET) on January 31, 2018, either party may terminate the Transaction Agreement and the Offer unless extended in accordance with the terms of the Transaction Agreement.

In addition, the Transaction Agreement may be terminated by either party under certain circumstances, including by Songa Offshore if the Songa Board modifies or withdraws its recommendation to Songa Offshore shareholders due to a Superior Proposal, as defined in “The Combination—The Transaction Agreement—No Solicitation of Transactions.”

Transocean must obtain governmental and regulatory approvals to consummate the Offer, which, if delayed or not granted, may delay or jeopardize the Offer and the transactions contemplated by the Transaction Agreement.

The approval of the Offer under merger control or competition law regimes in any jurisdictions where the parties to the Transaction Agreement have mutually determined merger control or competition law filings and/or notices to be necessary must have been obtained or any statutory waiting period (including any extension thereof) applicable to the Offer must have expired with the result that the Offer may be completed without the approval by any relevant antitrust authority.

The governmental and regulatory agencies from which Transocean may be required to seek these approvals have broad discretion in administering the applicable governing regulations. As a condition to their approval of the transactions contemplated by the Transaction Agreement, those agencies may impose requirements, limitations or costs or require divestitures or place restrictions on the conduct of Transocean’s business. No assurance can be given that the approvals, if required, will be obtained or that any required conditions to the Offer will be satisfied, and, if any such required approvals are obtained and the conditions to the consummation of the Offer are satisfied, no assurance can be given as to the terms, conditions and timing of the approvals. The Offer is subject to a regulatory condition that certain approvals are obtained. This condition may only be waived with the prior written consent of Songa Offshore.

Any delay in the completion of the Combination for regulatory reasons could diminish the anticipated benefits of the Combination or result in additional transaction costs. Any uncertainty over the ability to complete the Combination could make it more difficult for Transocean or Songa Offshore to maintain or to pursue particular business strategies. Conditions imposed by regulatory agencies in connection with their approval of the Combination may restrict the Company’s ability to modify the operations of its business in response to changing circumstances for a period of time after the closing of the Offer or its ability to expend cash for other uses or otherwise have an adverse effect on the anticipated benefits of the Combination, thereby adversely impacting the business, financial condition or results of operations of the combined company.

The announcement and pendency of the Offer and the other transactions contemplated by the Transaction Agreement, during which Transocean and Songa Offshore are subject to certain operating restrictions, could have an adverse effect on Songa Offshore’s and Transocean’s businesses and cash flows, financial condition and results of operations.

The announcement and pendency of the transactions contemplated by the Transaction Agreement, including the Offer, could disrupt Songa Offshore’s and Transocean’s businesses, and uncertainty about the effect of these transactions may

Table of Contents

have an adverse effect on Songa Offshore and Transocean. These uncertainties could cause suppliers, vendors, partners and others that deal with Transocean and Songa Offshore to defer entering into contracts with, or making other decisions concerning, Transocean and Songa Offshore or to seek to change or cancel existing business relationships with the companies. In addition, Songa Offshore’s and Transocean’s employees may experience uncertainty regarding their roles after the acquisition. Employees may depart either before or after the completion of the acquisition because of uncertainty and issues relating to the difficulty of coordination or because of a desire not to remain following the acquisition. Therefore, the pendency of the Offer may adversely affect Songa Offshore’s and Transocean’s ability to retain, recruit and motivate key personnel. Additionally, the attention of Songa Offshore’s and Transocean’s management may be directed towards the completion of the acquisition, including obtaining regulatory approvals, and may be diverted from the day-to-day business operations of Transocean and Songa Offshore. Matters related to the acquisition may require commitments of time and resources that could otherwise have been devoted to other opportunities that might have been beneficial to Transocean and Songa Offshore. Additionally, the Transaction Agreement requires Transocean and Songa Offshore to refrain from taking certain specified actions while the Offer and the acquisition are pending. These restrictions may prevent Transocean and Songa Offshore from pursuing otherwise attractive business opportunities or capital structure alternatives and from executing certain business strategies prior to the completion of the Offer. Further, the acquisition may give rise to potential liabilities, including those that may result from future shareholder lawsuits. Any of these matters could adversely affect the businesses of, or harm the results of operations, financial condition or cash flows of Transocean and Songa Offshore.

Negative publicity related to the transactions contemplated by the Transaction Agreement may materially adversely affect Transocean and Songa Offshore.

From time to time, political and public sentiment in connection with a proposed combination may result in a significant amount of adverse press coverage and other adverse public statements affecting Transocean and Songa Offshore. Adverse press coverage and public statements, whether or not driven by political or popular sentiment, may also result in legal claims or in investigations by regulators, legislators and law enforcement officials. Responding to these investigations and lawsuits, regardless of the ultimate outcome of the proceedings, can divert the time and effort of senior management from operating their businesses. Addressing any adverse publicity, governmental scrutiny or enforcement or other legal proceedings is time-consuming and expensive and, regardless of the factual basis for the assertions being made, could have a negative impact on the reputation of Transocean and Songa Offshore, on the morale of their employees and on their relationships with regulators. It may also have a negative impact on their ability to take timely advantage of various business and market opportunities. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have a material adverse effect on Songa Offshore’s and Transocean’s respective business and cash flows, financial condition and results of operations.

The share prices of Transocean and Songa Offshore may be adversely affected if the Offer is not completed.

If the Offer is not completed, the prices of Transocean shares and Songa Shares may decline to the extent that the current market prices of Transocean shares and Songa Shares reflect a market premium based on the assumption that the Offer will be completed.

The expected benefits associated with a combination of the Group and the Songa Group may not be realized.

Following the completion of the Offer, Transocean intends to integrate the two companies that have previously operated independently. There can be no assurances that Transocean will not encounter difficulties in integrating Songa Offshore’s operations or that the benefits expected from the integration will be realized. For example, completion of the Offer is expected to trigger change of control and acceleration provisions in certain of Songa Offshore’s existing indebtedness and agreements. Songa Offshore has received waivers, subject to certain conditions, for change of control provisions in certain of Songa Offshore's debt. Transocean also expects to refinance and/or repurchase certain of Songa Offshore's debt following the completion of the Offer. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Songa Offshore—Borrowings of the Songa Group” for further information on Songa Offshore's debt, and “Terms of the Offer—Refinancing of Certain Songa Offshore Indebtedness” for further information on the refinancing of debt. If the relevant waiver conditions are not met, if any necessary waiver extensions are not received from the relevant counterparties, or if Transocean is not able to refinance and/or repurchase certain of

Table of Contents

Songa Offshore’s debt on terms favorable to Transocean, Transocean may be required to make payments under the terms of that indebtedness or agreements that may limit its ability to fully integrate Songa Offshore’s business on the timeline it currently anticipates or that may prevent Transocean from fully realizing all of the benefits it currently anticipates from its acquisition of Songa Offshore. If the benefits are not achieved, or only partly achieved, this could adversely affect the Group’s business, financial condition, results of operations and prospects.

The Consideration Shares must be registered with the commercial register of the Canton of Zug, Switzerland before the Company can settle the Offer.

In order for the Company to issue the Consideration Shares to be delivered to the holders of Songa Shares, the Company must register the increase in its share capital and the issuance of the Consideration Shares with the commercial register of the Canton of Zug, Switzerland. Under Swiss law, registration may be blocked for reasons beyond the Company’s control, thereby delaying or preventing the issuance of the Consideration Shares and settlement of the Offer.

Risks Related to the Business of the Songa Group

Project Risk

It is customary in the drilling industry where the Songa Group operates that all contracts are charter related, e.g. structured as time charters or bareboat charters. The rationale for this is that drilling companies provide a service where the schedule and scope of work is controlled and ultimately directed by its customers. In some instances market participants may accept fixed prices for certain components of the overall contract work scope. Such instances include mobilization and demobilization of a unit to/from a worksite, and the conversion/upgrade of units to meet specific requirements as may be required for a specific project.

The Songa Group’s corporate policy is to seek to mitigate project risk at all times by having a strict policy on termination risk, breakdown risk, off-hire situations, force majeure risk etc. However, there can be made no assurance that the Songa Group will be able to sufficiently mitigate these project risks, and any such risk could negatively affect the financial position and results of operations of the Songa Group. The Songa Group has, following the drilling contract commencement for its four category d (“Cat D”) rigs, limited project risk.

Insurance and Uninsured Risk

Operational risks can inter alia cause personal injury, the loss of a unit, operational disruption, off hire and termination of contract. In order to mitigate these risks, the Songa Group has instigated an insurance program in line with market practice, and additional insurance is always considered when a specific project is considered to be of a high risk nature. The Songa Group has loss of hire insurance in place for its rigs, as part of a reduction of the overall risk profile of Songa Offshore.

Insurance policies and contractual rights to indemnity may not adequately cover losses, and the Songa Group does not have insurance coverage or rights to indemnity for all risks that could result from drilling operations. The Songa Group coverage includes annual aggregate policy limits. If a significant accident or other event occurs that is not fully covered by the insurance or an enforceable or recoverable indemnity from a client, the occurrence could adversely affect the Songa Group’s financial position, results of operations or cash flows.

Pollution and environmental risks generally are not fully insurable. The Songa Group’s insurance policies and contractual rights to indemnity may not adequately cover the Songa Group’s losses, or may have exclusions of coverage for some losses. The Songa Group does not have insurance coverage or rights to indemnity for all risks, including, among other things, liability risk for certain amounts of excess coverage and certain physical damage risk. If a significant accident or other event occurs which is not fully covered by insurance or contractual indemnity, it could adversely affect the financial position, results of operations and cash flows of the Songa Group.

Table of Contents

Reliance on Customers and Third Parties

The Songa Group has a strong dependency on Statoil ASA (“Statoil”). Statoil currently accounts for all the consolidated operating revenues of the Songa Group, and also represents all current contract revenue backlog of the Songa Group. While it is expected that Statoil will continue to be a significant customer going forward, there can be no assurance that this will be the case, and a discontinuation of the cooperation with major customers could have a material adverse effect on the Songa Group’s financial position and future prospects. The Songa Group relies on third parties to perform certain services for the operation of the drilling units, including maintenance and catering services and has significant agreements in place in that respect. A failure by one or more of these third parties to satisfactorily provide, on a timely basis, the agreed upon services may have an adverse impact on the Songa Group’s ability to perform its obligations under drilling contracts.

Rig Operation

The Songa Group only has a limited number of rigs. The Songa Group’s fleet is exposed to operational risks associated with offshore operations such as breakdown, bad weather, technical problems, force majeure situations (e.g., nationwide strikes), collisions, grounding and similar events, which may have a material adverse effect on the earnings and value of the Songa Group.

The drilling fleet of the Songa Group is concentrated in the semi-submersible rig market. Moreover, as the Songa Group’s fleet is configured to operate in the midwater sector, a reduction in demand for midwater drilling would have an adverse effect on the Songa Group. It would also be adversely affected by a reduction in demand for deepwater drilling, as some rigs configured for the deepwater sector (typically those equipped with mooring systems) can also operate in the midwater sector, thereby increasing the number of rigs operating in the midwater sector.

Without considering the Cat D rigs, which are high specifications semi-submersible, some of the Songa Group’s competitors have semi-submersible rigs with generally higher specifications than those in the current legacy fleet of the Songa Group. While the Songa Group does not believe that all higher specification rigs are suited to the midwater sector of the drilling industry, particularly during market downturns when there is decreased rig demand, some higher specification rigs may be more likely to compete with the Songa Group’s legacy fleet rigs in obtaining drilling contracts in the sector in which the Songa Group operates. In addition, higher specification rigs may be more adaptable to different operating conditions and have greater flexibility to move to areas of demand in response to changes in market conditions. Furthermore, in recent years, an increasing amount of exploration and production expenditures have been concentrated in deeper water drilling programs and deeper formations, thereby requiring higher specification rigs. This trend is expected to continue and could result in a material decline in demand for the lower specification rigs in the Songa Group’s fleet.

Charter Risk

The Songa Group provides its services on the basis of drilling contracts that are awarded through competitive bidding or to a lesser extent through direct negotiations with oil companies.

The Songa Group’s financial condition, operating results and cash flows could be adversely affected by early termination of contracts, contract renegotiations or cessation of day rates under any of the foregoing circumstances.

The Songa Group’s rigs are contracted to one customer, and a disruption in cooperation between the Songa Group and the customer could lead to a termination of most, or all, charter agreements. The ability of the Songa Group to renew contracts or obtain new contracts and the terms of any such contracts will depend, among other things, on market conditions, the specifications, suitability and deployment potential of its rigs, and the contractual terms, including day rates, that the Songa Group agrees to operate under. The Songa Group may be unable to renew expiring contracts or obtain new contracts for its rigs under contracts that have expired or been terminated, and the day rates under any new contracts may be substantially below existing day rates, which could materially reduce the revenues and profitability of the Songa Group. There can be no assurance that the Songa Group will be able to perform under its contracts due to

Table of Contents

events beyond its control or that the Songa Group will be able to ultimately execute a definitive agreement in cases where one does not currently exist. In addition, there can be no assurance that the Songa Group’s customers will be able to or willing to fulfil their contractual commitments to the Songa Group. There can be no assurance that the contracts included in the contract revenue backlog will generate the specified revenues or that the specified revenues will in fact be generated during the periods indicated.

The Songa Group’s financial condition, operating results and cash flows could be materially adversely affected by early termination of contracts, contract renegotiations or cessation of day rates under any of the foregoing circumstances.

Risk of Accidents

Offshore drilling units may work in harsh environments. The Songa Group’s operations are subject to the usual hazards inherent in drilling for oil offshore, such as breakdowns of vessels, blowouts, reservoir damage, loss of production, loss of well control, punch-through, craterings, groundings, collisions, fires, adverse weather conditions and natural disasters such as cyclones, storms and hurricanes. The Songa Group’s operations are also subject to accidents, which could be caused by various factors, including human error, adverse weather conditions or faulty construction.

The occurrence of any of the above events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury or death to rig personnel, damage to producing or potentially productive oil formations and environmental damage.

Operations also may be suspended because of machinery breakdowns, abnormal drilling conditions, failure of subcontractors to perform or supply goods or services or personnel shortages. In addition, offshore drilling operators are subject to perils peculiar to marine operations, including capsizing, grounding, collision and loss or damage from severe weather.

Damage to the environment could also result from its operations, particularly through oil spillage, extensive uncontrolled fires or a spill, leak or accident involving other hazardous substances that are stored on a rig. The Songa Group may also be subject to damage claims by oil and gas companies or other parties. An accident can have a material adverse effect on the Songa Group’s financial condition, and there can be no assurance that the Songa Group will have sufficient insurance against such losses and/or expenses.

Vessel operations are further subject to potential environmental liabilities which could be substantial. Such liabilities are difficult to estimate as the scope and amount of liability would, inter alia, depend on where the vessels are operated at the time when environmental damages occur.

Service Life and Technical Risk

The service life of a rig and/or vessel is generally assumed to be more than 30 years, but will ultimately depend on its efficiency. There can be no assurance that the Songa Group’s drilling units will be successfully deployed for such period of time. Although the Songa Group has four high specification midwater semi-submersible rigs, the remaining three rigs were all built in the 1970s and 1980s.

The capital associated with the repair and maintenance of each rig increases with age. In addition, there may be technical and environmental risks associated with ageing rigs, including operational problems and regulatory requirements leading to unexpectedly high operating/maintenance costs and/or lost earnings, and which may have a material adverse effect on the financial position of the Songa Group.

Unexpected Repair Cost

The timing and costs of repairs on the Songa Group’s drilling units are difficult to predict with certainty and may be substantial. Many of these expenses, such as dry-docking and certain repairs for normal wear and tear, are typically not

Table of Contents

covered by insurance. Large repair expenses could decrease the Songa Group’s profits. In addition, repair time may imply a loss of revenue for the Songa Group.

Risks Relating to the Songa Group’s Financial Situation

Significant Third Party Indebtedness

The Songa Group has a significant amount of third party indebtedness and there can be no assurances that the Songa Group in the future may not become in default of the terms of such. A breach of the terms of the Songa Group’s loan agreements may cause the lenders to require repayment of the financing immediately and to enforce the security granted over substantially all of the Songa Group’s assets, including its rigs. If the Songa Group’s operating cash flows are not sufficient to meet its operating expenses and the debt payment obligations of the Songa Group, the Songa Group may be forced to do one or more of the following: (i) delay or reduce capital expenditures; (ii) sell certain of its assets; (iii) forego business opportunities, including acquisitions and joint ventures, and/or (iv) obtain new capital, which may be dilutive to current stakeholders. The materialization of the aforementioned risks could have a material adverse impact on the financial position and/or results of operations of the Songa Group.

The Songa Group Has Exposure for Financial Covenants

The Songa Group’s credit and borrowing facilities contain financial and other covenants. There can be no assurance that the Songa Group will be able to meet all such covenants relating to current or future indebtedness contained in its funding agreements or that its lenders will extend waivers or amend terms to avoid any actual or anticipated breaches of such covenants.

Failure to comply with its financial and other covenants may have an adverse effect on the Songa Group’s financial condition, and also potential increased financial costs, requirements for additional security or cancellation of loans.

Financial Risks

The Songa Group monitors and manages the financial risks related to the operations of the Songa Group through internal reports and analysis. However, the Songa Group is exposed to various risks such as market risk (including currency risk, fair value interest rate risk and price risk), credit risk, liquidity risk and cash flow interest rate risk, and no assurances can be given that the monitoring of such risks will be adequate or sufficient. If the Songa Group fails to effectively monitor and manage such risks, this could have a material adverse impact on the financial position and/or results of operations of the Songa Group.

Foreign Exchange Risk Management

USD is the functional currency of Songa Offshore and all its subsidiaries. The Songa Group is exposed to foreign exchange risks related to its operations. The Company’s rig operating expenses, as well as its General & Administrative costs, are largely NOK-denominated. The Songa Encourage and Songa Enabler day rates are partly paid in NOK to provide a natural currency hedge, while for the other rigs the day rates are paid in USD only.

In order to manage its NOK exposure, Songa Offshore is actively using hedging instruments. Contracts are entered into when the Songa Group finds it in line with the overall interest rate risk strategy.

Interest Rate Risk Management

The Songa Group is exposed to fluctuations in interest rates for USD. The Songa Group’s interest costs on its credit facilities are subject to floating interest rate (the adjusted London Interbank Offered Rate referred to as “LIBOR”) plus a margin.

The risk is managed by maintaining an appropriate mix between fixed and floating rate borrowings and by the use of interest rate swaps. Contracts are entered into when the Songa Group finds it in line with the overall foreign exchange risk strategy.

Credit Risk Management

Due to the nature of the Songa Group’s operations, revenues and related receivables are typically concentrated amongst a relatively small customer base of international oil and gas companies. The majority of the revenues are generated by contracts with Statoil. The maximum credit risk is equal to the capitalized value of trade receivables and incurred revenue not billed.
