EXHIBIT 1.1

GLOBAL MARINE INC.

DEBT SECURITIES

UNDERWRITING AGREEMENT

1. Introductory. Global Marine Inc., a Delaware corporation ("Company"), proposes to issue and sell from time to time certain of its debt securities registered under the registration statements referred to in Section 2(a) ("Registered Securities"). The Registered Securities will be issued under the indenture, dated as of September 1, 1997, between the Company and Wilmington Trust Company, as Trustee, with respect to senior debt securities, or under an indenture to be entered into between the Company and a trustee, with respect to subordinated debt securities (the applicable indenture being referred to as the "Indenture"), in one or more series, which series may vary as to interest rates, maturities, redemption provisions, selling prices and other terms, with all such terms for any particular series of the Registered Securities being determined at the time of sale. Particular series of the Registered Securities will be sold pursuant to a Terms Agreement referred to in Section 3, for resale in accordance with terms of offering determined at the time of sale.

The Registered Securities involved in any such offering are hereinafter referred to as the "Securities." The firm or firms which agree to purchase the Securities are hereinafter referred to as the "Underwriters" of such Securities, and the representative or representatives of the Underwriters, if any, specified in a Terms Agreement referred to in Section 3 are hereinafter referred to as the "Representatives"; provided, however, that if the Terms Agreement does not specify any representative of the Underwriters, the term "Representatives," as used in this Agreement (other than in Sections 2(b), 5(c) and 6 and the second sentence of Section 3), shall mean the Underwriters.

2. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, each Underwriter that:

(a) Two registration statements (Nos. 33-58577 and 333-49807) relating to the Registered Securities have been filed with the Securities and Exchange Commission ("Commission") and have become effective; no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened under the Securities Act of 1933, as amended ("Act"). Pursuant to Rule 429 under the Act, the prospectus included in the second of such registration statements also relates to the first of such registration statements, and such registration statements are sometimes collectively referred to herein as one registration statement. Such registration statements, as amended at the time of any Terms Agreement referred to in
Section 3, including all material incorporated by reference therein, are hereinafter collectively referred to as the "Registration Statement," and the prospectus included in the Registration Statement, as supplemented as contemplated by Section 3 to reflect the terms of the Securities and the terms of offering thereof, as first filed with the

-1-

Commission pursuant to and in accordance with Rule 424(b) ("Rule 424(b)") under the Act, including all material incorporated by reference therein, is hereinafter referred to as the "Prospectus."

(b) On the effective date of each of the registration statements relating to the Registered Securities, such registration statements conformed in all material respects to the requirements of the Act, the Trust Indenture Act of 1939 ("Trust Indenture Act") and the rules and regulations of the Commission ("Rules and Regulations") and did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and on the date of each Terms Agreement referred to in
Section 3, the Registration Statement and the Prospectus will conform in all respects to the requirements of the Act, the Trust Indenture Act and the Rules and Regulations, and neither of such documents will include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, except that the foregoing does not apply to statements in or omissions from any of such documents based upon written information furnished to the Company by any Underwriter through the Representatives, if any, specifically for use therein.

(c) None of the Company or its subsidiaries (as defined in Section 1- 02(w) of Regulation S-X promulgated under the Act) ("Subsidiaries") is required to be registered or regulated as an "investment company" within the meaning of the Investment Company Act of 1940, as amended (the "Investment Company Act"), and after giving effect to the offer and sale of the Securities and the application of the proceeds thereof as described in the Prospectus, none of the Company or its Subsidiaries be required to be registered or regulated as an "investment company" as defined in the Investment Company Act.

(d) The Company has not paid or agreed to pay to any person any compensation for soliciting another to purchase any Securities (except as contemplated by the Terms Agreement).

(e) Except as set forth in the Prospectus, the Company and its Subsidiaries possess and are in compliance with all approvals, certificates, authorizations, licenses and permits issued by the appropriate state, Federal or foreign regulatory agencies or bodies necessary to conduct the business now being operated by them, except where the failure to possess such approvals, certificates, authorizations, licenses and permits or be in compliance therewith is not reasonably likely to have a material adverse effect on the condition, financial or otherwise, earnings, business or prospects of the Company and its Subsidiaries, taken as a whole (a "Material Adverse Effect"), and none of the Company or its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such approval, certificate, authorization, license or permit that individually or in the aggregate, is likely to have a Material Adverse Effect.

-2-

(f) Except as set forth in the Prospectus, there is no action, suit or proceeding before or by any court or governmental agency or body, domestic or foreign, now pending or, to the knowledge of the Company and its Subsidiaries threatened against the Company or any of its Subsidiaries that is likely to result in any Material Adverse Effect or materially and adversely affect the offering of the Securities in the manner contemplated by Prospectus.

(g) The Terms Agreement has been duly authorized, executed and delivered by the Company.

3. Purchase and Offering of Securities. The obligation of the Underwriters to purchase the Securities will be evidenced by an exchange of telegraphic or other written communications ("Terms Agreement") at the time the Company determines to sell the Securities. The Terms Agreement will incorporate by reference the provisions of this Agreement, except as otherwise provided therein, and will specify the firm or firms which will be Underwriters, the names of any Representatives, the principal amount of Securities to be purchased by each Underwriter, the purchase price to be paid by the Underwriters and the terms of the Securities not already specified in or pursuant to the Indenture, including, but not limited to, interest rate, maturity, any redemption provisions and any sinking fund requirements and whether any of the Securities may be sold to institutional investors pursuant to Delayed Delivery Contracts (as defined below). The Terms Agreement will also specify the time and date of delivery and payment (such time and date, or such other time not later than seven full business days thereafter as the Representatives and the Company agree as the time for payment and delivery, being herein and in the Terms Agreement referred to as the "Closing Date"), the place of delivery and payment and any details of the terms of offering that should be reflected in the prospectus supplement relating to the offering of the Securities. The obligations of the Underwriters to purchase the Securities will be several and not joint. It is understood that the Underwriters propose to offer the Securities for sale as set forth in the Prospectus. The Securities delivered to the Underwriters on the Closing Date will be in definitive fully registered form, in such denominations and registered in such names as the Underwriters may request.

If the Terms Agreement provides for sales of Securities pursuant to delayed delivery contracts, the Company authorizes the Underwriters to solicit offers to purchase Securities pursuant to delayed delivery contracts substantially in the form of Annex I attached hereto ("Delayed Delivery Contracts") with such changes therein as the Company may authorize or approve. Delayed Delivery Contracts are to be with institutional investors, including commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions. On the Closing Date the Company will pay, as compensation, to the Representatives for the accounts of the Underwriters, the fee set forth in such Terms Agreement in respect of the principal amount of Securities to be sold pursuant to Delayed Delivery Contracts ("Contract Securities"). The Underwriters will not have any responsibility in respect of the validity or the performance of Delayed Delivery Contracts. If the Company executes and delivers Delayed Delivery Contracts, the Contract Securities will be deducted from the Securities to be purchased by the several Underwriters and the aggregate principal amount of Securities to be purchased by each Underwriter will be

-3-

reduced pro rata in proportion to the principal amount of Securities set forth opposite each Underwriter's name in such Terms Agreement, except to the extent that the Representatives determine that such reduction shall be otherwise than pro rata and so advise the Company. The Company will advise the Representatives not later than the business day prior to the Closing Date of the principal amount of Contract Securities.

4. Certain Agreements of the Company. The Company agrees with the several Underwriters that it will furnish to Fulbright & Jaworski L.L.P., counsel for the Underwriters, one signed copy of the registration statement relating to the Registered Securities, including all exhibits, in the form it became effective and of all amendments thereto and that, in connection with each offering of Securities:

(a) The Company will file the Prospectus with the Commission pursuant to and in accordance with Rule 424(b) not later than the second business day following the execution and delivery of the Terms Agreement.

(b) The Company will advise the Representatives promptly of any proposal to amend or supplement the Registration Statement or the Prospectus and will afford the Representatives a reasonable opportunity to comment on any such proposed amendment or supplement; and the Company will also advise the Representatives promptly of the filing of any such amendment or supplement and of the institution by the Commission of any stop order proceedings in respect of the Registration Statement or of any part thereof and will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(c) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act, any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Prospectus to comply with the Act, the Company promptly will prepare and file with the Commission an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. The terms "supplement" and "amendment" as used in this Agreement shall include, without limitation, all documents filed by the Company with the Commission subsequent to the date of the Prospectus included in the Registration Statement which are deemed to be incorporated by reference in the Prospectus. Neither the Representatives' consent to, nor the Underwriters' delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 5.

(d) As soon as practicable, but not later than 16 months, after the date of each Terms Agreement, the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the later of (i) the

-4-

effective date of the registration statement relating to the Registered Securities, (ii) the effective date of the most recent post-effective amendment to the Registration Statement to become effective prior to the date of such Terms Agreement and (iii) the date of the Company's most recent Annual Report on Form 10-K filed with the Commission prior to the date of such Terms Agreement, which will satisfy the provisions of Section 11(a) of the Act.

(e) The Company will furnish to the Representatives copies of the Registration Statement, including all exhibits, any related preliminary prospectus, any related preliminary prospectus supplement, the Prospectus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as are reasonably requested.

(f) The Company will arrange for the qualification of the Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution; provided, however, that the Company will not be required in connection therewith to register or qualify as a foreign corporation where it is not now so qualified or to execute a general consent to service of process in any jurisdiction or subject itself to taxation in any jurisdiction where it is not then so subject.

(g) During the period of five years after the date of any Terms Agreement, the Company will furnish to the Representatives and, upon request, to each of the other Underwriters, if any, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Representatives (i) as soon as available, a copy of each report (other than on Form 11-K) or definitive proxy statement of the Company filed with the Commission under the Securities Exchange Act of 1934 ("Exchange Act") or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request.

(h) The Company will pay all expenses incident to the performance of its obligations under this Agreement and will reimburse the Underwriters for any expenses (including fees and disbursements of counsel) incurred by them in connection with qualification of the Registered Securities for sale and determination of their eligibility for investment under the laws of such jurisdictions as the Representatives may designate and the printing of memoranda relating thereto, for any fees charged by investment rating agencies for the rating of the Securities, for any filing fee of the National Association of Securities Dealers, Inc. relating to the Registered Securities and for expenses incurred in distributing the Prospectus, any preliminary prospectuses and any preliminary prospectus supplements to Underwriters.

5. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Securities will be subject to the accuracy of the

-5-

representations and warranties on the part of the Company herein, to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

(a) On or prior to each of the date of the Terms Agreement and the Closing Date, the Representatives shall have received letters, dated, respectively, as of the date of the Terms Agreement and the Closing Date, of Coopers & Lybrand, L.L.P., confirming that they are independent certified public accountants with respect to the Company under Rule 101 of the Code of Professional Conduct of the American Institute of Certified Public Accountants (the "AICPA"), and its interpretations and rulings, and stating in effect that:

(i) in their opinion, the audited financial statements and schedules examined by them and included or incorporated by reference in the prospectus contained in the registration statement relating to the Registered Securities, as amended at the date of such letter, comply in form in all material respects with the applicable accounting requirements of the Act and the related published Rules and Regulations;

(ii) on the basis of performing procedures specified by the AICPA for a review of interim financial information as described in SAS No. 71, Interim Financial Information, on the unaudited condensed consolidated financial statements; a reading of the minutes of the meetings of the directors and audit committee of the Company; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its subsidiaries as to transactions and events subsequent to the end of the Company's most recent fiscal year for which the Company has filed an Annual Report on Form 10-K, nothing came to their attention that caused them to believe that:

(1) any material modification should be made to the unaudited condensed consolidated financial statements included or incorporated by reference in such prospectus for them to be in conformity with generally accepted accounting principles;

(2) the unaudited condensed consolidated financial statements included or incorporated by reference in such prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and related published rules and regulations of the Commission;

(3) there were, at the date specified in the letter, any changes in the capital stock, increases in the long-term debt, or decreases in net current assets or shareholders' equity of the Company as compared with the amounts shown in the Company's most recent consolidated balance sheet included or

-6-

incorporated by reference in such prospectus, or for the period commencing immediately after the date of such balance sheet to the date specified in the letter, there were any decreases, as compared to the corresponding period in the preceding year, in consolidated revenues or in total or per-share amounts of net income except in all instances for changes, increases, or decreases that such prospectus discloses have occurred or may occur; or

(4) there was, at a specified date not more than five business days prior to the date of the letter, any change in the capital stock, increase in long-term debt or any decrease in consolidated net current assets or shareholders' equity of the Company as compared with amounts shown on the Company's most recent consolidated balance sheet included or incorporated by reference in such prospectus; or for the period commencing immediately after the date of such balance sheet to such specified date, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated revenues or in the total or per-share amounts of net income, except or changes, increases, or decreases that such prospectus or documents incorporated by reference therein discloses have occurred or may occur;

(iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company and its subsidiaries) set forth in such prospectus agrees with the accounting records of the Company and its subsidiaries, excluding any questions of legal interpretation; and

(iv) on the basis of a reading of any unaudited pro forma financial statements included or incorporated by reference in such prospectus ("pro forma financial statements"), inquiries of officials of the Company who have responsibility for financial and accounting matters, other specified procedures, and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in such pro forma financial statements, nothing came to their attention which caused them to believe that such pro forma financial statements do not comply in form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such pro forma statements.

All financial statements and schedules included in material incorporated by reference into such prospectus shall be deemed included in such prospectus for purposes of this subsection.

(b) The Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 4(a) of this Agreement. No stop order suspending the effectiveness of the Registration Statement or of any part thereof shall have been issued and

-7-

no proceedings for that purpose shall have been instituted or, to the knowledge of the Company or any Underwriter, shall be contemplated by the Commission.

(c) Subsequent to the execution of the Terms Agreement, or, if earlier, the dates of which information is given in such prospectus, there shall not have occurred (i) any change, or any development involving a prospective change, in or affecting particularly the business or properties of the Company or its subsidiaries; (ii) any downgrading in the rating of any debt securities of the Company by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Act), or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change; (iii) any suspension or limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Company by the Commission or the New York Stock Exchange; (iv) any banking moratorium declared by Federal or New York authorities; or (v) any outbreak or escalation of major hostilities in which the United States is involved, any declaration of war by the United States or a national emergency or war or other calamity or crisis the effect of which on financial markets which in any case referred to in clauses (i) through (v) above, is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Prospectus.

(d) The Representatives shall have received an opinion, dated the Closing Date, of Baker & Botts, L.L.P., counsel for the Company, to the effect that:

(i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own its properties and conduct its business as described in the Prospectus;

(ii) the Company's authorized equity capitalization is as set forth in the Prospectus under the caption "Capitalization;"

(iii) the Indenture has been duly authorized, executed and delivered by the Company and (assuming the due authorization, execution and delivery thereof by the Trustee) is a legal, valid and binding agreement of the Company enforceable against the Company in accordance with its terms, except as the enforcement of remedies thereof may be limited by applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or other laws affecting creditors' rights generally from time to time in effect and general principles of equity (regardless of whether considered in a proceeding in equity or at law); the Indenture has been duly qualified under the Trust Indenture Act; and the issuance and the sale of the Securities have been duly authorized by the Company, and the Securities, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and

-8-

paid for by the Underwriters in accordance with the terms of the Terms Agreement and, in the case of Contract Securities, the terms of the Delayed Delivery Contract, and in accordance with the terms of the Indenture, will constitute legal, valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except as the enforceability thereof may be subject to the effect of any applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or other laws affecting creditors' rights generally from time to time in effect and general principles of equity (regardless of whether considered in a proceeding in equity or at law); and the Securities other than any Contract Securities conform, and any Contract Securities, when so issued and delivered and sold, will conform, to the description thereof contained in the Prospectus;

(iv) the Terms Agreement and any Delayed Delivery Contracts have been duly authorized, executed and delivered by the Company and each of the Terms Agreement and any Delayed Delivery Contract is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforceability thereof may be subject to the effect of any applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or other laws affecting creditors' rights generally from time to time in effect and general principles of equity (regardless of whether considered in a proceeding in equity or at law), and except as rights to indemnity and contribution thereunder may be limited by any applicable laws or principles of public policy;

(v) to the knowledge of such counsel, no consent, approval, authorization or order of any court or governmental agency or body is required for the consummation of the transactions contemplated by the Terms Agreement, except such as may be required under the blue sky or securities laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriters (as to which such counsel need express no opinion), the Trust Indenture Act and such other approvals (specified in such opinion) as have been obtained;

(vi) neither the issue and sale of the Securities by the Company, the execution and delivery by the Company of the Indenture, the Terms Agreement and any Delayed Delivery Contracts and the consummation of any other of the transactions contemplated by the Terms Agreement nor the fulfillment of the terms hereof will conflict with, result in a breach or violation of, or constitute a default under (A) any law, (B) the certificate of incorporation or by-laws of the Company or (C) the terms of any indenture or other agreement or instrument providing for the borrowing of money known to such counsel and to which the Company or any of its subsidiaries is a party or bound except in the case of clauses (A) and (C) above, such conflict, breach, violation or default that is not, individually or in the aggregate reasonably likely to have a Material Adverse Effect;

-9-

(vii) the Registration Statement has become effective under the Act; any required filing of the Prospectus with the Commission pursuant to Rule 424(b) has been made in the manner and within the time period required thereby; and, to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened under the Act, and the registration statement relating to the Registered Securities, as of its most recent effective date, and the Prospectus, as of its issue date, and any amendment or supplement thereto, as of its effective or issue date (in each case, other than the financial statements and schedules, the notes thereto and the auditor's reports thereon, the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, as to which such counsel need not comment), appear on their face to comply as to form in all material respects with the requirements of the Act and the Rules and Regulations and the Trust Indenture Act; and

(viii) the Company is not required to be registered or regulated as an "investment company" within the meaning of the Investment Company Act.

Such counsel shall also state that such counsel has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company, representatives of the Underwriters and counsel to the Underwriters at which the contents of the Registration Statement and the Prospectus were discussed and, although such counsel did not independently verify such information and is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Prospectus, on the basis of the foregoing (relying as to factual matters upon statements of officers and other representatives of the Company and as to materiality to a large degree on officers and other representatives of the Company and representatives of the Underwriters) no facts came to such counsel's attention that led such counsel to believe that the Registration Statement (other than the financial statements and schedules, the notes thereto and the auditor's reports thereon, the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, and the exhibits thereto, as to which such counsel need express no belief) at the date of the Terms Agreement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that the Prospectus (other than the financial statements, the notes thereto and the auditor's report thereon and the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, as to which such counsel need express no belief) as of its issue date included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

-10-

In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of Delaware, the State of New York, the State of Texas or the United States, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing provided such opinions are also addressed to the Underwriters and are in form and substance satisfactory to them and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

(e) The Representatives shall have received an opinion, dated the Closing Date, of James L. McCulloch, general counsel of the Company, to the effect that:

(i) Each of Global Marine Drilling Company, Applied Drilling Technology Inc. and Global Marine Integrated Services - International Inc. (individually a "Specified Subsidiary" and collectively the "Specified Subsidiaries") has been duly incorporated and is validly existing as a corporation in good standing under the laws of the jurisdiction in which it is chartered or organized, with corporate power and authority to own its properties and conduct its business as described in the Prospectus, and the Company and each of the Specified Subsidiaries is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction which requires such qualification wherein it owns or leases material properties or conducts material business, except as would not have a Material Adverse Effect;

(ii) all the outstanding shares of capital stock of each Specified Subsidiary have been duly and validly authorized and issued and are fully paid and nonassessable, and, except as otherwise set forth in the Prospectus, all outstanding shares of capital stock of the Specified Subsidiaries are owned by the Company either directly or through wholly owned subsidiaries free and clear of any perfected security interest and, to the knowledge of such counsel, any other security interests, claims, liens or encumbrances;

(iii) the Company's authorized equity capitalization is as set forth in the Prospectus;

(iv) no consent, approval, authorization or order of any court or governmental agency or body is required for the consummation of the transactions contemplated by the Terms Agreement, except such as may be required under the blue sky or securities laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriters, as to which such counsel need express no opinion, and such other approvals (specified in such opinion) as have been obtained;

(v) neither the issue and sale of the Securities by the Company, the execution and delivery by the Company of the Indenture, the consummation of any other of the transactions therein contemplated nor the fulfillment of the terms of the Terms Agreement, will conflict with, result in a breach or violation of, or constitute a default under (A) any law, (B) the

-11-

certificate of incorporation or by-laws of the Company, (C) the terms of any indenture or other agreement or instrument known to such counsel and to which the Company or any of its Subsidiaries is a party or bound or (D) any judgment, order or decree known to such counsel to be applicable to the Company or its Specified Subsidiaries of any court, regulatory body, administrative agency, governmental body or arbitrator having jurisdiction over the Company or its Specified Subsidiaries except in the case of clauses (A), (C) and (D) above, such conflict, breach, violation or default that is not, individually or in the aggregate reasonably likely to have a Material Adverse Effect;

(vi) except as set forth in the Prospectus, the Company and its Specified Subsidiaries possess and are in compliance with all approvals, certificates, authorizations, licenses and permits issued by the appropriate state, Federal or foreign regulatory agencies or bodies necessary to conduct their business as described in the Prospectus, except where the failure to possess such approvals, certificates, authorizations, licenses and permits or be in compliance therewith would not be reasonably likely to have a Material Adverse Effect and to the knowledge of such counsel, none of the Company or its Specified Subsidiaries, has received any notice of proceedings relating to the revocation or modification of any such approval, certificate, authorization, license or permit which, individually or in the aggregate, if it became the subject of an unfavorable decision, ruling or finding, would be reasonably likely to have a Material Adverse Effect; and

(vii) to the knowledge of such counsel, there is no pending or threatened action, suit or proceeding before any court or government agency, authority or body or any arbitrator to which the Company or its Specified Subsidiaries is a party required to be described in the Registration Statement or Prospectus which are not described as required or of any contracts or documents of a character required to be described in the Registration Statement or Prospectus or to be filed as exhibits to the Registration Statement which are not described and filed as required.

Such counsel shall also state that such counsel has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company, representatives of the Underwriters and counsel to the Underwriters at which the contents of the Registration Statement and the Prospectus were discussed and, although such counsel did not independently verify such information and is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Prospectus, on the basis of the foregoing (relying as to factual matters upon statements of officers and other representatives of the Company and as to materiality to a large degree on officers and other representatives of the Company and representatives of the Underwriters) no facts came to such counsel's attention that led such counsel to believe that the Registration Statement (other than the financial statements and schedules, the notes thereto and the auditor's report thereon and the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, and the exhibits thereto, as to which

-12-

such counsel need express no belief) at the date of the Terms Agreement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that the Prospectus (other than the financial statements, the notes thereto and the auditor's report thereon and the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, as to which such counsel need express no belief) as of its issue date included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of Delaware, the State of Texas or the United States, to the extent he deems proper and specified in such opinion, upon the opinion of other counsel of good standing provided such opinions are also addressed to the Underwriters and are in form and substance satisfactorily to them and (B) as to matters of fact, to the extent he deems proper, on certificates of responsible officers of the Company and public officials.

(f) The Representatives shall have received from Fulbright & Jaworski L.L.P., counsel for the Underwriters, such opinion or opinions, dated the Closing Date, with respect to the issuance and sale of the Securities, the Indenture, the Registration Statement and the Prospectus and other related matters as the Underwriters may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(g) The Company shall have furnished to the Underwriters a certificate of the Company, signed by the Chairman of the Board or the President or any Vice President and the principal financial or accounting officer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Prospectus, any amendment or supplement to the Prospectus and the Terms Agreement and that:

(i) the representations and warranties of the Company in the Terms Agreement are true and correct in all material respects on and as of the Closing Date with the same effect as if made on the Closing Date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) since the date of the most recent financial statements included in the Prospectus (exclusive of any amendment or supplement thereof or thereto), there has been no material adverse change in the condition (financial or other), earnings, business or properties of the Company and its subsidiaries, whether or not arising from transactions in the ordinary course of business, except as set forth in or

-13-

contemplated in the Prospectus (exclusive of any amendment or supplement thereof or thereto); and

(iii) that no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are contemplated by the Commission.

(h) Prior to the Closing Date, the Company shall have furnished to the Underwriters such further information, certificates and documents as the Underwriters may reasonably request.

The Company will furnish the Representatives with such conformed copies of such opinions, certificates, letters and documents as they reasonably request.

6. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission in any of such documents, in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriters specifically for inclusion therein; provided further, that with respect to any untrue statement or omission of material fact made in any preliminary prospectus or preliminary prospectus supplement, the indemnity agreement contained in this Section 6(a) shall not inure to the benefit of any Underwriter from whom the person asserting any such loss, claim, damage or liability purchased the Securities concerned, to the extent that any such loss, claim, damage or liability of such Underwriter occurs under the circumstance where it shall have been determined by a court of competent jurisdiction by final and nonappealable judgment that (w) the Company had previously furnished copies of the Prospectus to the Underwriters, (x) delivery of the Prospectus was required to be made to such person, (y) the untrue statement or omission of a material fact contained in the preliminary prospectus was corrected in the Prospectus and (z) there was not sent or given to such person, at or

-14-

prior to the written confirmation of the sale of such Securities to such person, a copy of the Prospectus. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) Each Underwriter agrees to severally indemnify and hold harmless the Company, its directors, its officers and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter specifically for inclusion in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement. This indemnity agreement will be in addition to any liability that any Prospectus may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 6 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this
Section 6, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under Section 6(a) or 6(b) hereof unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in Section 6(a) or 6(b) hereof. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party, it being understood that the indemnifying party shall not be liable for more than one separate firm (in addition to one local counsel in each jurisdiction) for all indemnified parties in each jurisdiction in which any claim or action arising out of the same general allegations or circumstances is brought. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of

-15-

any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. An indemnifying party will not, without its prior consent, be liable for any settlement or compromise or consent to the entry of any judgment.

(d) In the event that the indemnity provided in Section 6(a) or 6(b) hereof is unavailable to or insufficient for any reason to hold harmless an indemnified party (other than as set forth therein), the Company and the Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and by the Underwriters from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among the Underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and of the Underwriters in connection with the statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering of the Securities (before deducting expenses), and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the Company or the Underwriters. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 6(d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each person who controls any Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this Section 6(d).

7. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Securities under the Terms Agreement and the aggregate principal amount of the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Securities, the Representatives may make

-16-

arrangements satisfactory to the Company for the purchase of such Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments under this Agreement and the Terms Agreement, to purchase the Securities that such defaulting Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of the Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Securities and arrangements satisfactory to the Representatives and the Company for the purchase of such Securities by other persons are not made within 36 hours after such default, such Terms Agreement will terminate without liability on the part of any nondefaulting Underwriter or the Company, except as provided in Section 6. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter of its liability, if any, to the Company or any non-defaulting Underwriter for damages occasioned by its default hereunder. The respective commitments of the several Underwriters for the purposes of this Section shall be determined without regard to reduction in the respective Underwriters' obligations to purchase the principal amounts of the Securities set forth opposite their names in the Terms Agreement as a result of Delayed Delivery Contracts entered into by the Company.

The foregoing obligations and agreements set forth in this Section will not apply if the Terms Agreement specifies that such obligations and agreements will not apply.

8. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person and will survive delivery of and payment for the Securities. If the Terms Agreement is terminated pursuant to
Section 7 or if for any reason the purchase of the Securities by the Underwriters under the Terms Agreement is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to
Section 4 and the respective obligations of the Company and the Underwriters pursuant to Section 6 shall remain in effect. If the purchase of the Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 7 or the occurrence of any event specified in clause (iii), (iv) or (v) of Section 5(c), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Securities.

9. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to them at their addresses furnished to the Company in writing for the purpose of communications hereunder or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at 777 North Eldridge Parkway, Houston, Texas 77079-4493, attention of General Counsel.

-17-

10. Successors. This Agreement will inure to the benefit of and be binding upon the Company and such Underwriters as are identified in Terms Agreements and their respective successors and the officers and directors and controlling persons referred to in Section 6, and no other person will have any right or obligation hereunder.

11. Applicable Law. This Agreement and the Terms Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York.

12. Headings. The headings contained in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

13. Counterparts. Any Terms Agreement may be executed in two or more counterparts, each of which will be deemed to be an original, but all such counterparts will together constitute one and the same instrument.

EXHIBIT 1.1

GLOBAL MARINE INC.

DEBT SECURITIES

UNDERWRITING AGREEMENT

1. Introductory. Global Marine Inc., a Delaware corporation ("Company"), proposes to issue and sell from time to time certain of its debt securities registered under the registration statements referred to in Section 2(a) ("Registered Securities"). The Registered Securities will be issued under the indenture, dated as of September 1, 1997, between the Company and Wilmington Trust Company, as Trustee, with respect to senior debt securities, or under an indenture to be entered into between the Company and a trustee, with respect to subordinated debt securities (the applicable indenture being referred to as the "Indenture"), in one or more series, which series may vary as to interest rates, maturities, redemption provisions, selling prices and other terms, with all such terms for any particular series of the Registered Securities being determined at the time of sale. Particular series of the Registered Securities will be sold pursuant to a Terms Agreement referred to in Section 3, for resale in accordance with terms of offering determined at the time of sale.

The Registered Securities involved in any such offering are hereinafter referred to as the "Securities." The firm or firms which agree to purchase the Securities are hereinafter referred to as the "Underwriters" of such Securities, and the representative or representatives of the Underwriters, if any, specified in a Terms Agreement referred to in Section 3 are hereinafter referred to as the "Representatives"; provided, however, that if the Terms Agreement does not specify any representative of the Underwriters, the term "Representatives," as used in this Agreement (other than in Sections 2(b), 5(c) and 6 and the second sentence of Section 3), shall mean the Underwriters.

2. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, each Underwriter that:

(a) Two registration statements (Nos. 33-58577 and 333-49807) relating to the Registered Securities have been filed with the Securities and Exchange Commission ("Commission") and have become effective; no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened under the Securities Act of 1933, as amended ("Act"). Pursuant to Rule 429 under the Act, the prospectus included in the second of such registration statements also relates to the first of such registration statements, and such registration statements are sometimes collectively referred to herein as one registration statement. Such registration statements, as amended at the time of any Terms Agreement referred to in
Section 3, including all material incorporated by reference therein, are hereinafter collectively referred to as the "Registration Statement," and the prospectus included in the Registration Statement, as supplemented as contemplated by Section 3 to reflect the terms of the Securities and the terms of offering thereof, as first filed with the

-1-

Commission pursuant to and in accordance with Rule 424(b) ("Rule 424(b)") under the Act, including all material incorporated by reference therein, is hereinafter referred to as the "Prospectus."

(b) On the effective date of each of the registration statements relating to the Registered Securities, such registration statements conformed in all material respects to the requirements of the Act, the Trust Indenture Act of 1939 ("Trust Indenture Act") and the rules and regulations of the Commission ("Rules and Regulations") and did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and on the date of each Terms Agreement referred to in
Section 3, the Registration Statement and the Prospectus will conform in all respects to the requirements of the Act, the Trust Indenture Act and the Rules and Regulations, and neither of such documents will include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, except that the foregoing does not apply to statements in or omissions from any of such documents based upon written information furnished to the Company by any Underwriter through the Representatives, if any, specifically for use therein.

(c) None of the Company or its subsidiaries (as defined in Section 1- 02(w) of Regulation S-X promulgated under the Act) ("Subsidiaries") is required to be registered or regulated as an "investment company" within the meaning of the Investment Company Act of 1940, as amended (the "Investment Company Act"), and after giving effect to the offer and sale of the Securities and the application of the proceeds thereof as described in the Prospectus, none of the Company or its Subsidiaries be required to be registered or regulated as an "investment company" as defined in the Investment Company Act.

(d) The Company has not paid or agreed to pay to any person any compensation for soliciting another to purchase any Securities (except as contemplated by the Terms Agreement).

(e) Except as set forth in the Prospectus, the Company and its Subsidiaries possess and are in compliance with all approvals, certificates, authorizations, licenses and permits issued by the appropriate state, Federal or foreign regulatory agencies or bodies necessary to conduct the business now being operated by them, except where the failure to possess such approvals, certificates, authorizations, licenses and permits or be in compliance therewith is not reasonably likely to have a material adverse effect on the condition, financial or otherwise, earnings, business or prospects of the Company and its Subsidiaries, taken as a whole (a "Material Adverse Effect"), and none of the Company or its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such approval, certificate, authorization, license or permit that individually or in the aggregate, is likely to have a Material Adverse Effect.

-2-

(f) Except as set forth in the Prospectus, there is no action, suit or proceeding before or by any court or governmental agency or body, domestic or foreign, now pending or, to the knowledge of the Company and its Subsidiaries threatened against the Company or any of its Subsidiaries that is likely to result in any Material Adverse Effect or materially and adversely affect the offering of the Securities in the manner contemplated by Prospectus.

(g) The Terms Agreement has been duly authorized, executed and delivered by the Company.

3. Purchase and Offering of Securities. The obligation of the Underwriters to purchase the Securities will be evidenced by an exchange of telegraphic or other written communications ("Terms Agreement") at the time the Company determines to sell the Securities. The Terms Agreement will incorporate by reference the provisions of this Agreement, except as otherwise provided therein, and will specify the firm or firms which will be Underwriters, the names of any Representatives, the principal amount of Securities to be purchased by each Underwriter, the purchase price to be paid by the Underwriters and the terms of the Securities not already specified in or pursuant to the Indenture, including, but not limited to, interest rate, maturity, any redemption provisions and any sinking fund requirements and whether any of the Securities may be sold to institutional investors pursuant to Delayed Delivery Contracts (as defined below). The Terms Agreement will also specify the time and date of delivery and payment (such time and date, or such other time not later than seven full business days thereafter as the Representatives and the Company agree as the time for payment and delivery, being herein and in the Terms Agreement referred to as the "Closing Date"), the place of delivery and payment and any details of the terms of offering that should be reflected in the prospectus supplement relating to the offering of the Securities. The obligations of the Underwriters to purchase the Securities will be several and not joint. It is understood that the Underwriters propose to offer the Securities for sale as set forth in the Prospectus. The Securities delivered to the Underwriters on the Closing Date will be in definitive fully registered form, in such denominations and registered in such names as the Underwriters may request.

If the Terms Agreement provides for sales of Securities pursuant to delayed delivery contracts, the Company authorizes the Underwriters to solicit offers to purchase Securities pursuant to delayed delivery contracts substantially in the form of Annex I attached hereto ("Delayed Delivery Contracts") with such changes therein as the Company may authorize or approve. Delayed Delivery Contracts are to be with institutional investors, including commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions. On the Closing Date the Company will pay, as compensation, to the Representatives for the accounts of the Underwriters, the fee set forth in such Terms Agreement in respect of the principal amount of Securities to be sold pursuant to Delayed Delivery Contracts ("Contract Securities"). The Underwriters will not have any responsibility in respect of the validity or the performance of Delayed Delivery Contracts. If the Company executes and delivers Delayed Delivery Contracts, the Contract Securities will be deducted from the Securities to be purchased by the several Underwriters and the aggregate principal amount of Securities to be purchased by each Underwriter will be

-3-

reduced pro rata in proportion to the principal amount of Securities set forth opposite each Underwriter's name in such Terms Agreement, except to the extent that the Representatives determine that such reduction shall be otherwise than pro rata and so advise the Company. The Company will advise the Representatives not later than the business day prior to the Closing Date of the principal amount of Contract Securities.

4. Certain Agreements of the Company. The Company agrees with the several Underwriters that it will furnish to Fulbright & Jaworski L.L.P., counsel for the Underwriters, one signed copy of the registration statement relating to the Registered Securities, including all exhibits, in the form it became effective and of all amendments thereto and that, in connection with each offering of Securities:

(a) The Company will file the Prospectus with the Commission pursuant to and in accordance with Rule 424(b) not later than the second business day following the execution and delivery of the Terms Agreement.

(b) The Company will advise the Representatives promptly of any proposal to amend or supplement the Registration Statement or the Prospectus and will afford the Representatives a reasonable opportunity to comment on any such proposed amendment or supplement; and the Company will also advise the Representatives promptly of the filing of any such amendment or supplement and of the institution by the Commission of any stop order proceedings in respect of the Registration Statement or of any part thereof and will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(c) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act, any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Prospectus to comply with the Act, the Company promptly will prepare and file with the Commission an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. The terms "supplement" and "amendment" as used in this Agreement shall include, without limitation, all documents filed by the Company with the Commission subsequent to the date of the Prospectus included in the Registration Statement which are deemed to be incorporated by reference in the Prospectus. Neither the Representatives' consent to, nor the Underwriters' delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 5.

(d) As soon as practicable, but not later than 16 months, after the date of each Terms Agreement, the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the later of (i) the

-4-

effective date of the registration statement relating to the Registered Securities, (ii) the effective date of the most recent post-effective amendment to the Registration Statement to become effective prior to the date of such Terms Agreement and (iii) the date of the Company's most recent Annual Report on Form 10-K filed with the Commission prior to the date of such Terms Agreement, which will satisfy the provisions of Section 11(a) of the Act.

(e) The Company will furnish to the Representatives copies of the Registration Statement, including all exhibits, any related preliminary prospectus, any related preliminary prospectus supplement, the Prospectus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as are reasonably requested.

(f) The Company will arrange for the qualification of the Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution; provided, however, that the Company will not be required in connection therewith to register or qualify as a foreign corporation where it is not now so qualified or to execute a general consent to service of process in any jurisdiction or subject itself to taxation in any jurisdiction where it is not then so subject.

(g) During the period of five years after the date of any Terms Agreement, the Company will furnish to the Representatives and, upon request, to each of the other Underwriters, if any, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Representatives (i) as soon as available, a copy of each report (other than on Form 11-K) or definitive proxy statement of the Company filed with the Commission under the Securities Exchange Act of 1934 ("Exchange Act") or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request.

(h) The Company will pay all expenses incident to the performance of its obligations under this Agreement and will reimburse the Underwriters for any expenses (including fees and disbursements of counsel) incurred by them in connection with qualification of the Registered Securities for sale and determination of their eligibility for investment under the laws of such jurisdictions as the Representatives may designate and the printing of memoranda relating thereto, for any fees charged by investment rating agencies for the rating of the Securities, for any filing fee of the National Association of Securities Dealers, Inc. relating to the Registered Securities and for expenses incurred in distributing the Prospectus, any preliminary prospectuses and any preliminary prospectus supplements to Underwriters.

5. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Securities will be subject to the accuracy of the

-5-

representations and warranties on the part of the Company herein, to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

(a) On or prior to each of the date of the Terms Agreement and the Closing Date, the Representatives shall have received letters, dated, respectively, as of the date of the Terms Agreement and the Closing Date, of Coopers & Lybrand, L.L.P., confirming that they are independent certified public accountants with respect to the Company under Rule 101 of the Code of Professional Conduct of the American Institute of Certified Public Accountants (the "AICPA"), and its interpretations and rulings, and stating in effect that:

(i) in their opinion, the audited financial statements and schedules examined by them and included or incorporated by reference in the prospectus contained in the registration statement relating to the Registered Securities, as amended at the date of such letter, comply in form in all material respects with the applicable accounting requirements of the Act and the related published Rules and Regulations;

(ii) on the basis of performing procedures specified by the AICPA for a review of interim financial information as described in SAS No. 71, Interim Financial Information, on the unaudited condensed consolidated financial statements; a reading of the minutes of the meetings of the directors and audit committee of the Company; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its subsidiaries as to transactions and events subsequent to the end of the Company's most recent fiscal year for which the Company has filed an Annual Report on Form 10-K, nothing came to their attention that caused them to believe that:

(1) any material modification should be made to the unaudited condensed consolidated financial statements included or incorporated by reference in such prospectus for them to be in conformity with generally accepted accounting principles;

(2) the unaudited condensed consolidated financial statements included or incorporated by reference in such prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and related published rules and regulations of the Commission;

(3) there were, at the date specified in the letter, any changes in the capital stock, increases in the long-term debt, or decreases in net current assets or shareholders' equity of the Company as compared with the amounts shown in the Company's most recent consolidated balance sheet included or

-6-

incorporated by reference in such prospectus, or for the period commencing immediately after the date of such balance sheet to the date specified in the letter, there were any decreases, as compared to the corresponding period in the preceding year, in consolidated revenues or in total or per-share amounts of net income except in all instances for changes, increases, or decreases that such prospectus discloses have occurred or may occur; or

(4) there was, at a specified date not more than five business days prior to the date of the letter, any change in the capital stock, increase in long-term debt or any decrease in consolidated net current assets or shareholders' equity of the Company as compared with amounts shown on the Company's most recent consolidated balance sheet included or incorporated by reference in such prospectus; or for the period commencing immediately after the date of such balance sheet to such specified date, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated revenues or in the total or per-share amounts of net income, except or changes, increases, or decreases that such prospectus or documents incorporated by reference therein discloses have occurred or may occur;

(iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company and its subsidiaries) set forth in such prospectus agrees with the accounting records of the Company and its subsidiaries, excluding any questions of legal interpretation; and

(iv) on the basis of a reading of any unaudited pro forma financial statements included or incorporated by reference in such prospectus ("pro forma financial statements"), inquiries of officials of the Company who have responsibility for financial and accounting matters, other specified procedures, and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in such pro forma financial statements, nothing came to their attention which caused them to believe that such pro forma financial statements do not comply in form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such pro forma statements.

All financial statements and schedules included in material incorporated by reference into such prospectus shall be deemed included in such prospectus for purposes of this subsection.

(b) The Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 4(a) of this Agreement. No stop order suspending the effectiveness of the Registration Statement or of any part thereof shall have been issued and

-7-

no proceedings for that purpose shall have been instituted or, to the knowledge of the Company or any Underwriter, shall be contemplated by the Commission.

(c) Subsequent to the execution of the Terms Agreement, or, if earlier, the dates of which information is given in such prospectus, there shall not have occurred (i) any change, or any development involving a prospective change, in or affecting particularly the business or properties of the Company or its subsidiaries; (ii) any downgrading in the rating of any debt securities of the Company by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Act), or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change; (iii) any suspension or limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Company by the Commission or the New York Stock Exchange; (iv) any banking moratorium declared by Federal or New York authorities; or (v) any outbreak or escalation of major hostilities in which the United States is involved, any declaration of war by the United States or a national emergency or war or other calamity or crisis the effect of which on financial markets which in any case referred to in clauses (i) through (v) above, is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Prospectus.

(d) The Representatives shall have received an opinion, dated the Closing Date, of Baker & Botts, L.L.P., counsel for the Company, to the effect that:

(i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own its properties and conduct its business as described in the Prospectus;

(ii) the Company's authorized equity capitalization is as set forth in the Prospectus under the caption "Capitalization;"

(iii) the Indenture has been duly authorized, executed and delivered by the Company and (assuming the due authorization, execution and delivery thereof by the Trustee) is a legal, valid and binding agreement of the Company enforceable against the Company in accordance with its terms, except as the enforcement of remedies thereof may be limited by applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or other laws affecting creditors' rights generally from time to time in effect and general principles of equity (regardless of whether considered in a proceeding in equity or at law); the Indenture has been duly qualified under the Trust Indenture Act; and the issuance and the sale of the Securities have been duly authorized by the Company, and the Securities, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and

-8-

paid for by the Underwriters in accordance with the terms of the Terms Agreement and, in the case of Contract Securities, the terms of the Delayed Delivery Contract, and in accordance with the terms of the Indenture, will constitute legal, valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except as the enforceability thereof may be subject to the effect of any applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or other laws affecting creditors' rights generally from time to time in effect and general principles of equity (regardless of whether considered in a proceeding in equity or at law); and the Securities other than any Contract Securities conform, and any Contract Securities, when so issued and delivered and sold, will conform, to the description thereof contained in the Prospectus;

(iv) the Terms Agreement and any Delayed Delivery Contracts have been duly authorized, executed and delivered by the Company and each of the Terms Agreement and any Delayed Delivery Contract is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforceability thereof may be subject to the effect of any applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or other laws affecting creditors' rights generally from time to time in effect and general principles of equity (regardless of whether considered in a proceeding in equity or at law), and except as rights to indemnity and contribution thereunder may be limited by any applicable laws or principles of public policy;

(v) to the knowledge of such counsel, no consent, approval, authorization or order of any court or governmental agency or body is required for the consummation of the transactions contemplated by the Terms Agreement, except such as may be required under the blue sky or securities laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriters (as to which such counsel need express no opinion), the Trust Indenture Act and such other approvals (specified in such opinion) as have been obtained;

(vi) neither the issue and sale of the Securities by the Company, the execution and delivery by the Company of the Indenture, the Terms Agreement and any Delayed Delivery Contracts and the consummation of any other of the transactions contemplated by the Terms Agreement nor the fulfillment of the terms hereof will conflict with, result in a breach or violation of, or constitute a default under (A) any law, (B) the certificate of incorporation or by-laws of the Company or (C) the terms of any indenture or other agreement or instrument providing for the borrowing of money known to such counsel and to which the Company or any of its subsidiaries is a party or bound except in the case of clauses (A) and (C) above, such conflict, breach, violation or default that is not, individually or in the aggregate reasonably likely to have a Material Adverse Effect;

-9-

(vii) the Registration Statement has become effective under the Act; any required filing of the Prospectus with the Commission pursuant to Rule 424(b) has been made in the manner and within the time period required thereby; and, to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened under the Act, and the registration statement relating to the Registered Securities, as of its most recent effective date, and the Prospectus, as of its issue date, and any amendment or supplement thereto, as of its effective or issue date (in each case, other than the financial statements and schedules, the notes thereto and the auditor's reports thereon, the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, as to which such counsel need not comment), appear on their face to comply as to form in all material respects with the requirements of the Act and the Rules and Regulations and the Trust Indenture Act; and

(viii) the Company is not required to be registered or regulated as an "investment company" within the meaning of the Investment Company Act.

Such counsel shall also state that such counsel has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company, representatives of the Underwriters and counsel to the Underwriters at which the contents of the Registration Statement and the Prospectus were discussed and, although such counsel did not independently verify such information and is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Prospectus, on the basis of the foregoing (relying as to factual matters upon statements of officers and other representatives of the Company and as to materiality to a large degree on officers and other representatives of the Company and representatives of the Underwriters) no facts came to such counsel's attention that led such counsel to believe that the Registration Statement (other than the financial statements and schedules, the notes thereto and the auditor's reports thereon, the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, and the exhibits thereto, as to which such counsel need express no belief) at the date of the Terms Agreement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that the Prospectus (other than the financial statements, the notes thereto and the auditor's report thereon and the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, as to which such counsel need express no belief) as of its issue date included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

-10-

In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of Delaware, the State of New York, the State of Texas or the United States, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing provided such opinions are also addressed to the Underwriters and are in form and substance satisfactory to them and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

(e) The Representatives shall have received an opinion, dated the Closing Date, of James L. McCulloch, general counsel of the Company, to the effect that:

(i) Each of Global Marine Drilling Company, Applied Drilling Technology Inc. and Global Marine Integrated Services - International Inc. (individually a "Specified Subsidiary" and collectively the "Specified Subsidiaries") has been duly incorporated and is validly existing as a corporation in good standing under the laws of the jurisdiction in which it is chartered or organized, with corporate power and authority to own its properties and conduct its business as described in the Prospectus, and the Company and each of the Specified Subsidiaries is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction which requires such qualification wherein it owns or leases material properties or conducts material business, except as would not have a Material Adverse Effect;

(ii) all the outstanding shares of capital stock of each Specified Subsidiary have been duly and validly authorized and issued and are fully paid and nonassessable, and, except as otherwise set forth in the Prospectus, all outstanding shares of capital stock of the Specified Subsidiaries are owned by the Company either directly or through wholly owned subsidiaries free and clear of any perfected security interest and, to the knowledge of such counsel, any other security interests, claims, liens or encumbrances;

(v) neither the issue and sale of the Securities by the Company, the execution and delivery by the Company of the Indenture, the consummation of any other of the transactions therein contemplated nor the fulfillment of the terms of the Terms Agreement, will conflict with, result in a breach or violation of, or constitute a default under (A) any law, (B) the

(vi) except as set forth in the Prospectus, the Company and its Specified Subsidiaries possess and are in compliance with all approvals, certificates, authorizations, licenses and permits issued by the appropriate state, Federal or foreign regulatory agencies or bodies necessary to conduct their business as described in the Prospectus, except where the failure to possess such approvals, certificates, authorizations, licenses and permits or be in compliance therewith would not be reasonably likely to have a Material Adverse Effect and to the knowledge of such counsel, none of the Company or its Specified Subsidiaries, has received any notice of proceedings relating to the revocation or modification of any such approval, certificate, authorization, license or permit which, individually or in the aggregate, if it became the subject of an unfavorable decision, ruling or finding, would be reasonably likely to have a Material Adverse Effect; and

(vii) to the knowledge of such counsel, there is no pending or threatened action, suit or proceeding before any court or government agency, authority or body or any arbitrator to which the Company or its Specified Subsidiaries is a party required to be described in the Registration Statement or Prospectus which are not described as required or of any contracts or documents of a character required to be described in the Registration Statement or Prospectus or to be filed as exhibits to the Registration Statement which are not described and filed as required.

Such counsel shall also state that such counsel has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company, representatives of the Underwriters and counsel to the Underwriters at which the contents of the Registration Statement and the Prospectus were discussed and, although such counsel did not independently verify such information and is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Prospectus, on the basis of the foregoing (relying as to factual matters upon statements of officers and other representatives of the Company and as to materiality to a large degree on officers and other representatives of the Company and representatives of the Underwriters) no facts came to such counsel's attention that led such counsel to believe that the Registration Statement (other than the financial statements and schedules, the notes thereto and the auditor's report thereon and the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, and the exhibits thereto, as to which

-12-

such counsel need express no belief) at the date of the Terms Agreement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that the Prospectus (other than the financial statements, the notes thereto and the auditor's report thereon and the other financial, numerical, statistical and accounting data included or incorporated by reference therein, or omitted therefrom, as to which such counsel need express no belief) as of its issue date included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of Delaware, the State of Texas or the United States, to the extent he deems proper and specified in such opinion, upon the opinion of other counsel of good standing provided such opinions are also addressed to the Underwriters and are in form and substance satisfactorily to them and (B) as to matters of fact, to the extent he deems proper, on certificates of responsible officers of the Company and public officials.

(f) The Representatives shall have received from Fulbright & Jaworski L.L.P., counsel for the Underwriters, such opinion or opinions, dated the Closing Date, with respect to the issuance and sale of the Securities, the Indenture, the Registration Statement and the Prospectus and other related matters as the Underwriters may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

The Company will furnish the Representatives with such conformed copies of such opinions, certificates, letters and documents as they reasonably request.

6. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission in any of such documents, in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriters specifically for inclusion therein; provided further, that with respect to any untrue statement or omission of material fact made in any preliminary prospectus or preliminary prospectus supplement, the indemnity agreement contained in this Section 6(a) shall not inure to the benefit of any Underwriter from whom the person asserting any such loss, claim, damage or liability purchased the Securities concerned, to the extent that any such loss, claim, damage or liability of such Underwriter occurs under the circumstance where it shall have been determined by a court of competent jurisdiction by final and nonappealable judgment that (w) the Company had previously furnished copies of the Prospectus to the Underwriters, (x) delivery of the Prospectus was required to be made to such person, (y) the untrue statement or omission of a material fact contained in the preliminary prospectus was corrected in the Prospectus and (z) there was not sent or given to such person, at or

-14-

prior to the written confirmation of the sale of such Securities to such person, a copy of the Prospectus. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) Each Underwriter agrees to severally indemnify and hold harmless the Company, its directors, its officers and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter specifically for inclusion in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement. This indemnity agreement will be in addition to any liability that any Prospectus may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 6 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this
Section 6, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under Section 6(a) or 6(b) hereof unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in Section 6(a) or 6(b) hereof. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party, it being understood that the indemnifying party shall not be liable for more than one separate firm (in addition to one local counsel in each jurisdiction) for all indemnified parties in each jurisdiction in which any claim or action arising out of the same general allegations or circumstances is brought. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of

-15-

any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. An indemnifying party will not, without its prior consent, be liable for any settlement or compromise or consent to the entry of any judgment.

(d) In the event that the indemnity provided in Section 6(a) or 6(b) hereof is unavailable to or insufficient for any reason to hold harmless an indemnified party (other than as set forth therein), the Company and the Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and by the Underwriters from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among the Underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and of the Underwriters in connection with the statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering of the Securities (before deducting expenses), and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the Company or the Underwriters. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 6(d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each person who controls any Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this Section 6(d).

7. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Securities under the Terms Agreement and the aggregate principal amount of the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Securities, the Representatives may make

-16-

arrangements satisfactory to the Company for the purchase of such Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments under this Agreement and the Terms Agreement, to purchase the Securities that such defaulting Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of the Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Securities and arrangements satisfactory to the Representatives and the Company for the purchase of such Securities by other persons are not made within 36 hours after such default, such Terms Agreement will terminate without liability on the part of any nondefaulting Underwriter or the Company, except as provided in Section 6. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter of its liability, if any, to the Company or any non-defaulting Underwriter for damages occasioned by its default hereunder. The respective commitments of the several Underwriters for the purposes of this Section shall be determined without regard to reduction in the respective Underwriters' obligations to purchase the principal amounts of the Securities set forth opposite their names in the Terms Agreement as a result of Delayed Delivery Contracts entered into by the Company.

The foregoing obligations and agreements set forth in this Section will not apply if the Terms Agreement specifies that such obligations and agreements will not apply.

8. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person and will survive delivery of and payment for the Securities. If the Terms Agreement is terminated pursuant to
Section 7 or if for any reason the purchase of the Securities by the Underwriters under the Terms Agreement is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to
Section 4 and the respective obligations of the Company and the Underwriters pursuant to Section 6 shall remain in effect. If the purchase of the Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 7 or the occurrence of any event specified in clause (iii), (iv) or (v) of Section 5(c), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Securities.

9. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to them at their addresses furnished to the Company in writing for the purpose of communications hereunder or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at 777 North Eldridge Parkway, Houston, Texas 77079-4493, attention of General Counsel.

-17-

10. Successors. This Agreement will inure to the benefit of and be binding upon the Company and such Underwriters as are identified in Terms Agreements and their respective successors and the officers and directors and controlling persons referred to in Section 6, and no other person will have any right or obligation hereunder.

11. Applicable Law. This Agreement and the Terms Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York.

12. Headings. The headings contained in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

13. Counterparts. Any Terms Agreement may be executed in two or more counterparts, each of which will be deemed to be an original, but all such counterparts will together constitute one and the same instrument.

EXHIBIT 4.1

GLOBAL MARINE INC.

7% Notes Due 2028

A series of Securities is hereby established pursuant to Section 2.01 of the Indenture dated as of September 1, 1997 between Global Marine Inc. (the "Company") and Wilmington Trust Company (the "Trustee"), as follows:

1. The title of the Securities of the series shall be "7% Notes Due 2028" (the "Notes").

2. The limit upon the aggregate principal amount of the Notes that may be authenticated and delivered under the Indenture (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of other Notes pursuant to Sections 2.08, 2.09, 2.12, 3.07 or 9.05 of the Indenture) is $300,000,000.

3. The Notes shall be issued as permanent Global Securities (as defined in the Indenture) under the Indenture. The Depository Trust Company is hereby designated as the Depositary for the Global Securities under the Indenture.

4. The date on which the principal of the Notes is payable shall be June 1, 2028.

5. The rate at which each of the Notes shall bear interest shall be 7% per annum. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The date from which interest shall accrue for each of the Notes shall be May 26, 1998. The Interest Payment Dates (as defined in the Indenture) on which interest on the Notes shall be payable are June 1 and December 1, commencing December 1, 1998. Interest on the Notes shall be payable to the persons in whose name the Notes are registered at the close of business on the Record Date (as defined below) for such interest payment. The record dates (each a "Record Date") for the interest payable on the Notes on any Interest Payment Date shall be the May 15 and November 15, as the case may be, immediately preceding such interest payment date.

6. The place or places where the principal of, premium (if any) on and interest on the Notes shall be payable is at the office or agency of the Trustee in New York, New York. Payments in respect of the Notes evidenced by a Global Security (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Holder (as defined in the Indenture) of the Global Note. In all other cases, payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear in the register of the Notes maintained by the Registrar (as defined in the Indenture).

1

7. The Notes will be redeemable, at the option of the Company, at any time, in whole or from time to time in part, upon not less than 30 and not more than 60 days' notice as provided in the Indenture, on any date prior to maturity (the "Redemption Date") at a price (the "Redemption Price") equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date) plus the Make-Whole Premium, if any. In no event will the Redemption Price ever be less than 100% of the principal amount of the Notes plus accrued interest to the Redemption Date.

The amount of the Make-Whole Premium with respect to any Note (or portion thereof) to be redeemed will be equal to the excess, if any, of:

(i) the sum of the present values, calculated as of the Redemption Date, of:

(A) each interest payment that, but for such redemption, would have been payable on the Note (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued interest for the period prior to the Redemption Date); and

(B) the principal amount that, but for such redemption, would have been payable at the final maturity of the Notes (or portion thereof) being redeemed;

over

(ii) the principal amount of the Note (or portion thereof) being redeemed.

The present values of interest and principal payments referred to in clause (i) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for the redemption, to the Redemption Date at a discount rate equal to the Treasury Yield (as defined below) plus 30 basis points.

The Make-Whole Premium shall be calculated by an independent investment banking institution of national standing appointed by the Company; provided, that if the Company fails to make such appointment at least 45 business days prior to the Redemption Date, or if the institution so appointed is unwilling or unable to make such calculation, such calculation shall be made by Morgan Stanley & Co. Incorporated or, if such firm is unwilling or unable to make such calculation, by an independent investment banking institution of national standing appointed by the Trustee (in any such case, an "Independent Investment Banker").

For purposes of determining the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the Notes, calculated to the nearest 1/12th of a year (the "Remaining Term"). The Treasury Yield shall be

2

determined as of the third Business Day (as defined in the Indenture) immediately preceding the applicable Redemption Date. The weekly average yields of United States Treasury Notes shall be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15 (519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield shall be equal to such weekly average yield. In all other cases, the Treasury Yield shall be calculated by interpolation, on a straight-line basis, between the weekly average yields on the United States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields as calculated by interpolation shall be rounded to the nearest 1/100th of 1%, with any figure of 1/200% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield shall be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

8. The Notes shall not be entitled to the benefit of any sinking fund or other mandatory redemption provisions.

9. The Notes shall be in substantially the form of Annex A hereto (the "Form of Note").

10. Each Note that is a Global Security shall bear the legend set forth on the face of the Form of Note.

[REVERSE OF SECURITY]

GLOBAL MARINE INC.

7% NOTE DUE 2028

This Security is one of a duly authorized issue of __% Notes Due 2028 (the "Securities") of Global Marine Inc., a Delaware corporation (the "Company").

1. Interest. The Company promises to pay interest on the principal amount of this Security at 7% per annum from May 26, 1998 until maturity. The Company will pay interest semiannually on June 1 and December 1 of each year (each an "Interest Payment Date"), or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Securities will accrue from the most recent Interest Payment Date on which interest has been paid or, if no interest has been paid, from May 26, 1998; provided that if there is no existing Default in the payment of interest, and if this Security is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be December 1, 1998. The Company shall pay interest on overdue principal from time to time on demand at a rate equal to the interest rate then in effect; it shall pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment. The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the record date next preceding the Interest Payment Date, even if such Securities are canceled after such record date and on or before such Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect principal payments. The Company will pay the principal of and interest on the Securities in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. The Company, however, may pay such amounts by check payable in such money. Payments in respect of the Securities evidenced by a Global Security (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Holder of the Global Security. In all other cases, payment of interest may be made at the option of the Company by check to a Holder's registered address.

3. Paying Agent and Registrar. Initially, Wilmington Trust Company (the "Trustee"), the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar, co-registrar or additional paying agent without notice to any Holder. The Company may act in any such capacity.

4. Indenture. The Company issued the Securities under an Indenture dated as of September 1, 1997 (the "Indenture") between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb) (the "TIA"), as in

3

effect on the date of execution of the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Securities are unsecured general obligations of the Company limited to $300,000,000 in aggregate principal amount. The Indenture provides for the issuance of other series of debt securities (including the Securities, the "Debt Securities") thereunder.

5. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not exchange or register the transfer of any Securities during the period between a record date and the corresponding Interest Payment Date or of any Security selected for redemption, except the unredeemed portion of any Security being redeemed in part.

6. Persons Deemed Owners. The registered Holder of a Security shall be treated as its owner for all purposes.

7. Redemption. The Securities will be redeemable, at the option of the Company, at any time in whole or from time to time in part, upon not less than 30 and not more than 60 days' notice as provided in the Indenture, on any date prior to maturity (the "Redemption Date") at a price (the "Redemption Price") equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date) plus the Make-Whole Premium, if any. In no event will the Redemption Price ever be less than 100% of the principal amount of the Securities plus accrued interest to the Redemption Date.

The amount of the Make-Whole Premium with respect to any Security (or portion thereof) to be redeemed will be equal to the excess, if any, of:

(i) the sum of the present values, calculated as of the Redemption Date, of:

(A) each interest payment that, but for such redemption, would have been payable on the Security (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued interest for the period prior to the Redemption Date); and

(B) the principal amount that, but for such redemption, would have been payable at the final maturity of the Securities (or portion thereof) being redeemed;

over

(ii) the principal amount of the Security (or portion thereof) being redeemed.

4

The present values of interest and principal payments referred to in clause (i) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for the redemption, to the Redemption Date at a discount rate equal to the Treasury Yield plus 30 basis points.

The Make-Whole Premium shall be calculated by an independent investment banking institution of national standing appointed by the Company; provided, that if the Company fails to make such appointment at least 45 business days prior to the Redemption Date, or if the institution so appointed is unwilling or unable to make such calculation, such calculation shall be made by Morgan Stanley & Co. Incorporated or, if such firm is unwilling or unable to make such calculation, by an independent investment banking institution of national standing appointed by the Trustee (in any such case, an "Independent Investment Banker").

For purposes of determining the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the Securities, calculated to the nearest 1/12th of a year (the "Remaining Term"). The Treasury Yield shall be determined as of the third Business Day (as defined in the Indenture) immediately preceding the applicable Redemption Date. The weekly average yields of United States Treasury Notes shall be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15
(519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield shall be equal to such weekly average yield. In all other cases, the Treasury Yield shall be calculated by interpolation, on a straight-line basis, between the weekly average yields on the United States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields as calculated by interpolation shall be rounded to the nearest 1/100th of 1%, with any figure of 1/200% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield shall be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

8. Amendments and Waivers. Subject to certain exceptions and limitations, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Debt Securities of all series of Debt Securities affected by such amendment or supplement (acting as one class), and any existing or past Default or Event of Default under, or compliance with any provision of, the Indenture may be waived (other than any continuing Default or Event of Default in the payment of the principal of or interest on the Securities) by the Holders of at least a majority in principal amount of the then outstanding Debt Securities of any series or of all series (acting as one class) in accordance with the terms of the Indenture. Without the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities or waive any provision of either, to cure any

5

ambiguity, omission, defect or inconsistency; to comply with the provisions of the Indenture relating to merger, consolidation and certain other transactions; to provide for uncertificated Securities in addition to or in place of certificated Securities; to provide any security for the Securities or to add guarantees of the Securities; to comply with any requirement in order to effect or maintain the qualification of the Indenture under the TIA; to add to the covenants of the Company for the benefit of the Holders of the Securities, or to surrender any right or power conferred by the Indenture upon the Company; to add any additional Events of Default with respect to all or any series of the Debt Securities; to change or eliminate any of the provisions of the Indenture, provided that no Security is adversely affected in any material respect; to supplement any of the provisions of the Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of the Securities pursuant to the Indenture; or to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Securities and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts thereunder by more than one Trustee, pursuant to the requirements of the Indenture.

The right of any Holder to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date fixed in accordance with the terms of the Indenture.

Without the consent of each Holder affected, the Company may not (i) reduce the amount of Debt Securities whose Holders must consent to an amendment, supplement or waiver, (ii) reduce the rate of or change the time for payment of interest, including default interest, on any Security, (iii) reduce the principal of or premium on, or change the Stated Maturity of, any Security, (iv) reduce the premium, if any, payable upon the redemption of any Security or change the time at which any Security may or shall be redeemed, (v) change the coin or currency in which any Security or any premium or interest with respect thereto are payable, (vi) impair the right to institute suit for the enforcement of any payment of principal of or premium (if any) or interest on any Security,
(vii) make any change in the percentage of principal amount of Debt Securities necessary to waive compliance with certain provisions of the Indenture or (viii) waive a continuing Default or Event of Default in the payment of principal of or premium (if any) or interest on the Securities.

A supplemental indenture that changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of Debt Securities under the Indenture, or which modifies the rights of the Holders of Debt Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Debt Securities of any other series.

9. Defaults and Remedies. Events of Default are defined in the Indenture and generally include: (i) default by the Company for 30 days in payment of any interest on the Securities; (ii) default by the Company in any payment of principal of (or premium, if any, on) the Securities; (iii) default by the Company in compliance with any of its other covenants or agreements in, or provisions of, the Securities or in the Indenture which shall not have been remedied within 90 days after written notice by the Trustee or by the holders of at least 25% in principal amount of the

Securities then outstanding (or, in the event that other Debt Securities issued under the Indenture are also affected by the default, then 25% in principal amount of all outstanding Debt Securities so affected); or (iv) certain events involving bankruptcy, insolvency or reorganization of the Company. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities of the series affected by such default (or, in the case of an Event of Default described in clause (iii) above, if outstanding Debt Securities of other series are affected by such Default, then at least 25% in principal amount of the then outstanding Debt Securities so affected), may declare the principal of and interest on all the Securities to be immediately due and payable, except that in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization of the Company, all outstanding Securities become due and payable immediately without further action or notice. The amount due and payable upon the acceleration of any Security is equal to 100% of the principal amount thereof plus accrued interest to the date of payment. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity reasonably satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities (or affected Debt Securities) may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee.

10. Discharge Prior to Maturity. The Indenture with respect to the Securities shall be discharged and canceled upon the payment of all of the Securities and shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of funds or U.S. Government Obligations sufficient for such payment.

11. Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee.

12. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

13. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

14. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed thereon.
