         ITEM 5.   OTHER EVENTS.

              On September 19, 1997, the Registrant completed the sale of
         $1,150,000,000 principal amount of its 3 1/8% Exchangeable
         Subordinated Notes due September 15, 2007 (the "Notes"), 
         including $150,000,000 principal amount of Notes to cover over-
         allotments.  The Notes are exchangeable into shares of common
         stock, par value $.01 per share (the "Daimond Offshore Common
         Stock"), of Diamond Offshore Drilling, Inc. ("Diamond Offshore")
         from October 1, 1998 to September 15, 2007, subject to certain  
         blackout rights of Diamond Offshore contained in the Amendment
         to the Registration Rights Agreement, dated as of September 16,
         1997, between the Registrant and Diamond Offshore (the  
         "Registration Rights Agreement Amendment").  The Notes have been
         issued pursuant to the terms, and subject to the conditions,
         contained in the Indenture, dated as of December 1, 1985,
         between the Registrant and The Chase Manhattan Bank (as

         Second Supplemental Indentures, each dated as of February 18,
         1997, between the Registrant and the Trustee, and as supplemented
         by the Third Supplemental Indenture, dated as of September 19, 
         1997, between the Registrant and the Trustee (the "Third

              On September 23, 1997, the Registrant issued a press release
         announcing the completion of the sale of the Notes and stating 
         that, at the time the sale of the Notes was consummated, the 
         Registrant owned approximately 50.3% of the outstanding Diamond 
         Offshore Common Stock.  A copy of the press release is filed as 
         an exhibit hereto and is incorporated by reference herein.

                      $1,000,000,000 aggregate principal amount
                   3-1/8% Exchangeable Subordinated Notes due 2007

                               UNDERWRITING AGREEMENT



                                                 September 16, 1997


         To the Representatives named in Schedule I hereto
         of the Underwriters named in Schedule II hereto

         Ladies and Gentlemen:

              Loews Corporation, a Delaware corporation (the "Company"),
         proposes to issue and sell to the underwriters named in Schedule
         II hereto (the "Underwriters"), for whom you are acting as
         representatives (the "Representatives"), the principal amount of
         its securities identified in Schedule I hereto (the "Securities"),
         which may be senior or subordinated debt securities (the "Debt
         Securities") or any combination thereof.

              The Debt Securities will be issued in one or more series as
         senior indebtedness (the "Senior Debt Securities") under an
         indenture, dated as of March 1, 1986, between the Company and The
         Chase Manhattan Bank (National Association), as trustee (the
         "Trustee"), as supplemented by a first supplemental indenture,
         dated March 30, 1993, between the Company and the Trustee and a
         second supplemental indenture, dated as of February 18, 1997,
         between the Company and the Trustee (such Indenture, as
         supplemented, is referred to as the "Senior Indenture"), or as
         subordinated indebtedness (the "Subordinated Debt Securities")
         under an indenture, dated as of December 1, 1985, between the
         Company and the Trustee, as supplemented by a first supplemental
         indenture, dated as of February 18, 1997, between the Company and
         the Trustee, a second supplemental indenture, dated as of February
         18, 1997, between the Company and the Trustee and a third
         supplemental indenture, dated as of September 19, 1997, between
         the Company and the Trustee (such Indenture, as supplemented, is
         referred to as the "Subordinated Indenture," and collectively with
         the Senior Indenture, the "Indentures," and each, an "Indenture").
         Each series of Debt Securities may vary, as applicable, as to
         title, aggregate principal amount, rank, interest rate or formula
         and timing of payments thereof, stated maturity date, redemption
         and/or repayment provisions, sinking fund requirements, conversion
         provisions (and terms of the related Underlying Securities) and
         any other variable terms established by or pursuant to the
         applicable Indenture.





              As used herein, "Securities" means the Senior Debt Securities
         or Subordinated Debt Securities, or any combination thereof,
         initially issuable by the Company and, if Securities are
         convertible or exchangeable, "Underlying Securities" means the
         securities (of the Company or another issuer) issuable upon
         conversion or exchange of the Senior Debt Securities or
         Subordinated Debt Securities, as applicable.

              Schedule I hereto specifies the number or aggregate principal
         amount, as the case may be, of Securities to be initially issued
         (the "Initial Underwritten Securities"), whether such offering is
         on a fixed or variable price basis and, if on a fixed price basis,
         the initial offering price, the price at which the Initial
         Underwritten Securities are to be purchased by the Underwriters,
         the form, time, date and place of delivery and payment of the
         Initial Underwritten Securities and any other material variable
         terms of the Initial Underwritten Securities, as well as the
         material variable terms of any related Underlying Securities.  In
         addition, if applicable, such Underwriting Agreement shall specify
         whether the Company has agreed to grant to the Underwriters an
         option to purchase additional Securities to cover overallotments,
         if any, and the number or aggregate principal amount, as the case
         may be, of Securities subject to such option (the "Option
         Underwritten Securities").  As used herein, the term "Underwritten
         Securities" shall include the Initial Underwritten Securities and
         all or any portion of any Option Underwritten Securities.

              The Company has filed with the Securities and Exchange
         Commission (the "Commission") a registration statement on Form S-3
         (No. 333-22113) for the registration of the Securities under the
         Securities Act of 1933, as amended (the "Act"), and the offering
         thereof from time to time in accordance with Rule 415 of the rules
         and regulations of the Commission under the Act (the "Act
         Regulations"), and the Company has filed such post-effective
         amendments thereto as may be required prior to the execution of
         this Underwriting Agreement.  Such registration statement (as so
         amended, if applicable) has been declared effective by the
         Commission and each Indenture has been duly qualified under the
         Trust Indenture Act of 1939, as amended (the "Trust Indenture
         Act").  Such registration statement (as so amended, if
         applicable), including the information, if any, deemed to be a
         part thereof pursuant to Rule 430A(b) of the Act Regulations (the
         "Rule 430A Information") or Rule 434(d) of the Act Regulations
         (the "Rule 434 Information"), is referred to herein as the
         "Registration Statement"; and the final prospectus and the final
         prospectus supplement relating to the offering of the Underwritten
         Securities, in the form first furnished to the Underwriters by the
         Company for use in connection with the offering of the
         Underwritten Securities, are collectively referred to herein as
         the "Final Prospectus"; provided, however, that all references to
         the "Registration Statement" and the "Final Prospectus" shall also
         be deemed to include all documents incorporated therein by
         reference pursuant to the Securities Exchange Act of 1934, as
         amended (the "Exchange Act"), prior to the execution of this
         Underwriting Agreement; provided further, that if the Company
         files a registration statement with the Commission pursuant to
         Rule 462(b) of the Act Regulations (the "Rule 462 Registration
         Statement"), then, after such filing, all references to
         "Registration Statement" shall also be deemed to include the Rule
         462 Registration Statement; and provided further, that if the
         Company elects to rely upon 


                                         -2-





         Rule 434 of the Act Regulations, then all references to "Final
         Prospectus" shall also be deemed to include the final or
         preliminary prospectus and the applicable term sheet or
         abbreviated term sheet (the "Term Sheet"), as the case may be, in
         the form first furnished to the Underwriters by the Company in
         reliance upon Rule 434 of the Act Regulations, and all references
         in this Underwriting Agreement to the date of the Final Prospectus
         shall mean the date of the Term Sheet.  A "Preliminary Prospectus"
         shall be deemed to refer to any prospectus used before the
         registration statement became effective and any prospectus that
         omitted, as applicable, the Rule 430A Information, the Rule 434
         Information or other information to be included upon pricing in a
         form of prospectus filed with the Commission pursuant to Rule
         424(b) of the Act Regulations, that was used after such
         effectiveness and prior to the execution and delivery of this
         Underwriting Agreement.  For purposes of this Underwriting
         Agreement, all references to the Registration Statement, Final
         Prospectus, Term Sheet or Preliminary Prospectus or to any
         amendment or supplement to any of the foregoing shall be deemed to
         include any copy filed with the Commission pursuant to its
         Electronic Data Gathering, Analysis and Retrieval system
         ("EDGAR").  Notwithstanding anything to the contrary in this
         Underwriting Agreement, if any revised Term Sheet, Preliminary
         Prospectus or Final Prospectus, as the case may be, shall be
         provided to the Underwriters by the Company for use in connection
         with the offering of the Securities which differs from the
         prospectus on file at the Commission at the time the Registration
         Statement becomes effective (whether or not such revised
         prospectus is required to be filed by the Company pursuant to Rule
         424(b) of the Act Regulations), the terms "Term Sheet,"
         "Preliminary Prospectus" or "Final Prospectus," as the case may
         be, shall refer to such revised "Term Sheet," "Preliminary
         Prospectus" or "Final Prospectus" from and after the time it is
         first provided to the Underwriters for such use.  Any reference
         herein to the terms "amend," "amendment" or "supplement" with
         respect to the Registration Statement, Term Sheet, any Preliminary
         Prospectus or the Final Prospectus, unless otherwise expressly
         provided therein, shall be deemed to refer to and include the
         filing of any document under the Exchange Act after the date of
         this Underwriting Agreement, or the issue date of the Preliminary
         Prospectus or the Final Prospectus, as the case may be, deemed to
         be incorporated therein by reference.

              All references in this Underwriting Agreement to financial
         statements and schedules and other information which is
         "contained," "included" or "stated" (or other references of like
         import) in the Registration Statement, Final Prospectus or
         Preliminary Prospectus shall be deemed to mean and include all
         such financial statements and schedules and other information
         which is incorporated by reference in the Registration Statement,
         Final Prospectus or Preliminary Prospectus, as the case may be;
         and all references in this Underwriting Agreement to amendments or
         supplements to the Registration Statement, Final Prospectus or
         Preliminary Prospectus shall be deemed to mean and include the
         filing of any document under the Exchange Act which is
         incorporated by reference in the Registration Statement, Final
         Prospectus or Preliminary Prospectus, as the case may be.

              1A.  Representations and Warranties of the Company.  The
         Company represents and warrants to each Underwriter as of the date
         hereof and as of the Closing Date that:

         under the Act.

              (b)  This Underwriting Agreement has been duly authorized,
         executed and delivered by the Company.  The Indenture is
         substantially in the form filed as an exhibit to the Registration
         Statement at the time the Registration Statement became effective
         (other than insofar as the Indenture has been modified by a
         supplemental Indenture), and, has been duly authorized, executed
         and delivered by the Company and constitutes a legal, valid and
         binding agreement of the Company, enforceable against the Company
         in accordance with its terms, except that (A) the enforceability
         thereof may be subject to bankruptcy, insolvency, reorganization,
         moratorium or other similar laws now or hereafter in effect,
         relating to creditors' rights generally and (B) the remedy of
         specific performance and injunctive and other forms of equitable
         relief may be subject to equitable defenses and to the discretion
         of the court before which any proceeding therefor may be brought.
         An Amendment to the Registration Rights Agreement, dated October
         16, 1995, between the Company and Diamond Offshore Drilling, Inc.
         ("Diamond Offshore"), in the form of Exhibit A hereto, has been
         duly authorized by the Company and, as of the Closing Date, will
         be duly executed and delivered by the Company (as so amended, such
         Registration Rights Agreement is referred to as the "Amended
         Registration Rights Agreement").

              (c)  Each of the Registration Statement and any Rule 462(b)
         Registration Statement has become effective under the Act and no
         stop order suspending the effectiveness of the Registration
         Statement or any Rule 462(b) Registration Statement has been
         issued under the Act and no proceedings for that purpose have been
         instituted or are pending or, to the knowledge of the Company, are
         contemplated by the Commission, and any request on the part of the
         Commission for additional information has been complied with.  In
         addition, each Indenture has been duly qualified under the Trust
         Indenture Act.

              At the respective times the Registration Statement, any Rule
         462(b) Registration Statement and any post-effective amendments
         thereto (including the filing of the Company's most recent Annual
         Report on Form 10-K with the Commission (the "Annual Report on
         Form 10-K")) became effective and as of the date hereof, the
         Registration Statement, any Rule 462(b) Registration Statement and
         any amendments and supplements thereto complied and will comply in
         all material respects with the requirements of the Act and the Act
         Regulations and the Trust Indenture Act and the rules and
         regulations of the Commission under the Trust Indenture Act (the

         contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make
         the statements therein not misleading.  At the date of the Final
         Prospectus, at the Closing Date and at each Date of Delivery, if
         any, the Final Prospectus and any amendments and supplements
         thereto did not and will not include an untrue statement 


                                         -4-





         of a material fact or omit 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.  If the
         Company elects to rely upon Rule 434 of the Act Regulations, the
         Company will comply with the requirements of Rule 434.
         Notwithstanding the foregoing, the representations and warranties
         in this subsection (c) shall not apply to (i) statements in or
         omissions from the Registration Statement or the Final Prospectus
         made in reliance upon and in conformity with information furnished
         to the Company in writing by or on behalf of any Underwriter
         expressly for use in the Registration Statement or the Final
         Prospectus or (ii) that part of the Registration Statement which
         shall constitute the Statement of Eligibility and Qualification
         (Form T-1) under the Trust Indenture Act of the Trustee.

              Each preliminary prospectus and prospectus filed as part of
         the Registration Statement as originally filed or as part of any
         amendment thereto, or filed pursuant to Rule 424 under the Act,
         complied when so filed in all material respects with the Act
         Regulations and each Preliminary Prospectus and the Final
         Prospectus delivered to the Underwriters for use in connection
         with the offering of Underwritten Securities will, at the time of
         such delivery, be identical to any electronically transmitted
         copies thereof filed with the Commission pursuant to EDGAR, except
         to the extent permitted by Regulation S-T.

              (d)  The documents incorporated or deemed to be incorporated
         by reference in the Registration Statement and the Final
         Prospectus as of the date hereof, when they became effective or at
         the time they were or hereafter are filed with the Commission,
         complied and will comply in all material respects with the
         requirements of the Exchange Act and the rules and regulations of
         the Commission thereunder (the "Exchange Act Regulations").

              (e)  The Company has been duly organized and is validly
         existing as a corporation in good standing under the laws of the
         State of Delaware and has corporate power and authority to own,
         lease and operate its properties and to conduct its business as
         described in the Final Prospectus and to enter into and perform
         its obligations under, or as contemplated under, this Underwriting
         Agreement.  The Company is duly qualified as a foreign corporation
         to transact business and is in good standing in each other
         jurisdiction in which such qualification is required, whether by
         reason of the ownership or leasing of material property or the
         conduct of material business, except where the failure to so
         qualify or be in good standing would not result in a material
         adverse change in the condition (financial or other), earnings,
         business or properties of the Company and its subsidiaries, taken
         as a whole, whether or not arising from transactions in the
         ordinary course of business (a "Material Adverse Effect").

              (f)  The Underwritten Securities have been duly authorized by
         the Company for issuance and sale pursuant to this Underwriting
         Agreement.  Such Underwritten 


                                         -5-





         Securities, when issued and authenticated in the manner provided
         for in the applicable Indenture and delivered against payment of
         the consideration therefor specified in this Underwriting
         Agreement, will constitute valid and legally binding obligations
         of the Company, enforceable against the Company in accordance with
         their terms, except as the enforcement thereof may be limited by
         bankruptcy, insolvency, reorganization, moratorium or other
         similar laws relating to or affecting creditors' rights generally
         or by general equitable principles, and except further as
         enforcement thereof may be limited by (A) governmental authority
         to limit, delay or prohibit the making of payments outside the
         United States and (B) the remedy of specific performance and
         injunctive and other forms of equitable relief may be subject to
         equitable defenses and to the discretion of the court before which
         any proceeding therefor may be brought.  Such Underwritten
         Securities will be in the form contemplated by, and each
         registered holder thereof is entitled to the benefits of, the
         applicable Indenture.

              (g)  The Underwritten Securities being sold pursuant to this
         Underwriting Agreement and each applicable Indenture, as of the
         date of the Final Prospectus, will conform in all material
         respects to the statements relating thereto contained in the Final
         Prospectus.  The Underwritten Securities will be in substantially
         the form filed or incorporated by reference, as the case may be,
         as an exhibit to the Registration Statement.

              (h)  The execution and delivery of this Underwriting
         Agreement, each applicable Indenture, the Amended Registration
         Rights Agreement, and any other agreement or instrument entered
         into or issued or to be entered into or issued by the Company in
         connection with the transactions contemplated hereby or thereby or
         in the Registration Statement and the Final Prospectus and the
         consummation of the transaction contemplated herein and in the
         Registration Statement and the Final Prospectus (including the
         issuance and sale of the Underwritten Securities and the use of
         the proceeds from the sale of the Underwritten Securities as
         described under the caption "Use of Proceeds") and compliance by
         the Company with its obligations hereunder and thereunder have
         been duly authorized by all necessary corporate action and will
         not conflict with or constitute a breach of, or default under, or
         result in the creation or imposition of any lien, charge or
         encumbrance upon any property or assets of the Company or any of
         its subsidiaries pursuant to, any agreements or instruments, nor
         will such action result in any violation of the provisions of the
         charter or by-laws of the Company or any of its subsidiaries or
         any applicable law, administrative regulation or administrative or
         court decree which, in the aggregate, could reasonably be expected
         to result in a Material Adverse Effect.

              (i)  The statements set forth in the Final Prospectus under
         the captions "Description of Senior Debt Securities", "Description
         of Subordinated Debt Securities", "Description of Preferred
         Stock", "Description of Common Stock", "Description of the Notes"

         insofar as they purport to constitute a summary of the terms of
         the Securities, are accurate, complete and fair.

              (j)  Neither the Company nor any of its affiliates does
         business with the government of Cuba or with any person or
         affiliate located in Cuba within the meaning of Section 517.075,
         Florida Statutes.

              1B.  Representations and Warranties of Diamond Offshore.
         Diamond Offshore represents and warrants to each Underwriter as of
         the date hereof and as of the Closing Date that:

                   (a)  Diamond Offshore's annual report on Form 10-K for
              the fiscal year ended December 31, 1996 (the "Form 10-K"),
              its definitive proxy statement on Schedule 14A filed with the
              Commission on April 1, 1997, its quarterly reports on Form
              10-Q for the quarters ended March 31, 1997 and June 30, 1997
              and any current reports on Form 8-K filed by Diamond Offshore
              subsequent to the Form 10-K are hereinafter referred to
              collectively as the "Exchange Act Reports".  The Exchange Act
              Reports, when they were filed with the Commission, conformed
              in all material respects to the applicable requirements of
              the Exchange Act and the applicable rules and regulations of
              the Commission thereunder, and did not, and on the date of
              the Final Prospectus, will not, contain an untrue statement
              of a material fact or omit 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.  To
              the extent that any statement made or omitted in the
              Registration Statement, the Final Prospectus or any amendment
              or supplement thereto are made or omitted in reliance upon
              and in conformity with written information furnished to the
              Company by Diamond Offshore expressly for use therein, such
              Registration Statement did, and the Final Prospectus and any
              further amendments or supplements to the Registration
              Statement and the Final Prospectus will, when they become
              effective or are filed with the Commission, as the case may
              be, conform in all material respects to the requirements of
              the Act and the Act Regulations and not contain 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.

                   (b)  Diamond Offshore has been duly incorporated and is
              an existing corporation in good standing under the laws of
              the State of Delaware, with power and authority (corporate
              and other) to own its properties and conduct its business as
              described in the Final Prospectus; and Diamond Offshore is
              duly qualified to do business as a foreign corporation in
              good standing in all other jurisdictions in which its
              ownership or lease of property or the conduct of its business
              requires such qualification, except where the failure of
              Diamond Offshore to be so qualified would not have a material
              adverse effect on the business, operations or financial
              condition of Diamond Offshore and its subsidiaries, taken as
              a whole.


                                         -7-





                   (c)  Each subsidiary of Diamond Offshore has been duly
              incorporated and is an existing corporation in good standing
              under the laws of the jurisdiction of its incorporation, with
              power and authority (corporate and other) to own its
              properties and conduct its business as described in the Final
              Prospectus; and each subsidiary of Diamond Offshore is duly
              qualified to do business as a foreign corporation in good
              standing in all other jurisdictions in which its ownership or
              lease of property or the conduct of its business requires
              such qualification, except where the failure of such
              subsidiary to be so qualified would not have a material
              adverse effect on the business, operations or financial
              condition of Diamond Offshore and its subsidiaries, taken as
              a whole; all of the issued and outstanding capital stock of
              each subsidiary of Diamond Offshore has been duly authorized
              and validly issued and is fully paid and nonassessable,
              except where the failure of such capital stock to have been
              so authorized and issued would not have a material adverse
              effect on the business, operations or financial condition of
              Diamond Offshore and its subsidiaries, taken as a whole; and
              the capital stock of each subsidiary owned by Diamond
              Offshore, directly or through subsidiaries, is owned free
              from liens, encumbrances and defects, except where the
              failure of Diamond Offshore to so own such capital stock
              would not have a material adverse effect on the business,
              operations, properties or financial condition of Diamond
              Offshore and its subsidiaries, taken as a whole.

                   (d)  The Amended Registration Rights Agreement has been
              duly authorized by Diamond Offshore and, on the Closing Date,
              will be duly executed and delivered by Diamond Offshore.

                   (e)  The Underlying Securities deliverable upon exchange
              of the Underwritten Securities and all other outstanding
              shares of capital stock of Diamond Offshore have been duly
              authorized and are validly issued, fully paid and
              nonassessable; the Underlying Securities conform to the
              description thereof contained in the Final Prospectus and,
              when delivered in accordance with the terms of the related
              Underwritten Securities, will conform to the description
              thereof contained in the Final Prospectus as the same may be
              amended or supplemented; and the stockholders of Diamond
              Offshore have no preemptive rights with respect to the
              Underlying Securities.

                   (f)  Except as disclosed in the Final Prospectus, there
              are no contracts, agreements or understandings between
              Diamond Offshore and any person that would give rise to a
              valid claim against Diamond Offshore or any Underwriter for a
              brokerage commission, finder's fee or other like payment
              relating to the issuance of the Underwritten Securities or
              the exchange thereof for the Underlying Securities.

                   (g)  Except for the Amended Registration Rights
              Agreement, there are no currently effective contracts,
              agreements or understandings between Diamond 


                                         -8-





              Offshore and any person granting such person the right to
              require Diamond Offshore to file a registration statement
              under the Act with respect to any securities of Diamond
              Offshore owned or to be owned by such person or to require
              Diamond Offshore to include such securities in any securities
              being registered pursuant to any registration statement filed
              by Diamond Offshore under the Act.

                   (h)  The outstanding shares of common stock of Diamond
              Offshore, including the Underlying Securities, are listed on
              the New York Stock Exchange.

                   (i)  No consent, approval, authorization, or order of,
              or filing with, any governmental agency or body or any court
              is required to be obtained by Diamond Offshore for the
              consummation of the transactions contemplated by this
              Underwriting Agreement or in connection with the exchange of
              the Underwritten Securities for the Underlying Securities,
              except such as have been (or, under the Amended Registration
              Rights Agreement, will have been) obtained and made under the
              Act and such as may be required under state securities laws.

                   (j)  The execution, delivery and performance of the
              Amended Registration Rights Agreement and this Underwriting
              Agreement and compliance with the terms and provisions
              thereof will not conflict with or result in a breach or
              violation of any of the terms or provisions of, or constitute
              a default under, any indenture, mortgage, deed of trust, loan
              agreement or other agreement or instrument to which Diamond
              Offshore or any of its subsidiaries is a party or by which
              Diamond Offshore or any of its subsidiaries is bound, or to
              which any of the property or assets of Diamond Offshore or
              any of its subsidiaries is subject, nor will such action
              result in any violation of the provisions of the charter or
              bylaws of Diamond Offshore or any of its subsidiaries or any
              statute or any order, rule or regulation of any court or
              governmental agency or body having jurisdiction over Diamond
              Offshore or any of its subsidiaries or the property of
              Diamond Offshore or any of its subsidiaries except, in each
              case other than with respect to such charter or bylaws, which
              conflict, breach or default or violation would not impair
              Diamond Offshore's or any of its subsidiaries' ability to
              perform the obligations hereunder or have any material
              adverse effect upon the consummation of the transactions
              contemplated hereby or any Underwriter.

                   (k)  This Underwriting Agreement has been duly
              authorized, executed and delivered by Diamond Offshore.

                   (l)  Except as disclosed in the Exchange Act Reports or
              the Final Prospectus and except for Permitted Liens, as such
              term is defined below, Diamond Offshore and its subsidiaries
              have good and marketable title to all offshore drilling rigs
              described as being owned by them in the Exchange Act Reports
              or the Final Prospectus, and good and marketable title to all
              real property and all other properties and assets owned by
              them, in each case free from liens, encumbrances and defects

                                         -9-





              affect the value thereof, taken as a whole, or materially
              interfere with the use made or to be made thereof by them;
              and except as disclosed in the Exchange Act Reports or the
              Final Prospectus, Diamond Offshore and its subsidiaries hold
              any leased real or personal property under valid and
              enforceable leases with no exceptions to such validity or
              enforceability that would materially interfere with the use
              made or to be made thereof by them.  "Permitted Liens" means
              (i) liens for taxes not yet due or liens that have not been
              filed for taxes that are being contested in good faith and by
              appropriate proceedings diligently prosecuted; (ii)
              carriers', warehousemen's, mechanics', materialmen's,
              repairmen's, maritime, statutory or other like liens arising

              and by appropriate proceedings diligently prosecuted; (iii)
              pledges or deposits in connection with workmen's
              compensation, unemployment insurance and other social
              security legislation; and (iv) deposits to secure the
              performance of bids, contracts in the ordinary course of
              business (other than for borrowed money), leases, statutory
              obligations, surety and appeal bonds and performance bonds,
              and other obligations of a like nature that are incurred in
              the ordinary course of business.

                   (m)  Diamond Offshore and its subsidiaries possess
              adequate certificates, authorities or permits issued by
              appropriate governmental agencies or bodies necessary to
              conduct the business now operated by them in all material
              respects and have not received any notice of proceedings
              relating to the revocation or modification of any such
              certificate, authority or permit that, if determined
              adversely to Diamond Offshore or any of its subsidiaries,
              would individually or in the aggregate have a material
              adverse effect on Diamond Offshore and its subsidiaries taken
              as a whole.

                   (n)  No labor dispute with the employees of Diamond
              Offshore or any subsidiary exists or, to the knowledge of
              Diamond Offshore, is imminent that would reasonably be
              expected to have a material adverse effect on Diamond
              Offshore and its subsidiaries taken as a whole.

                   (o)  Diamond Offshore and its subsidiaries own, possess
              or can acquire on reasonable terms, adequate trademarks,
              trade names and other rights to inventions, know-how,
              patents, copyrights, confidential information and other
              intellectual property (collectively, "intellectual property
              rights") necessary to conduct the business now operated by
              them, or presently employed by them, and have not received
              any notice of infringement of or conflict with asserted
              rights of others with respect to any intellectual property
              rights that, if determined adversely to Diamond Offshore or
              any of its subsidiaries, would individually or in the
              aggregate have a material adverse effect on Diamond Offshore
              and its subsidiaries taken as a whole.

                   (p)  Except as disclosed in the Exchange Act Reports or
              the Final Prospectus, neither Diamond Offshore nor any of its
              subsidiaries is in violation of any statute, any rule,
              regulation, decision or order of any governmental agency or
              body or any court, 


                                        -10-





              domestic or foreign, relating to the use, disposal or release
              of hazardous or toxic substances or relating to the
              protection or restoration of the environment or human
              exposure to hazardous or toxic substances (collectively,
              "environmental laws"), owns or operates any real property
              contaminated with any substance that is subject to any
              environmental laws, is liable for any off-site disposal or
              contamination pursuant to any environmental laws, or is
              subject to any claim relating to any environmental laws,
              which violation, contamination, liability or claim would
              individually or in the aggregate have a material adverse
              effect on Diamond Offshore and its subsidiaries taken as a
              whole; and Diamond Offshore is not aware of any pending
              investigation which might lead to such a claim.

                   (q)  There are no pending actions, suits or proceedings
              against or affecting Diamond Offshore, any of its
              subsidiaries or any of their respective properties except as
              disclosed in the Exchange Act Reports or the Final
              Prospectus, or as individually or in the aggregate do not now
              have and, to the best knowledge of Diamond Offshore, are not
              reasonably expected in the future to have a material adverse
              effect on the condition (financial or other), business,
              properties or results of operations of Diamond Offshore and
              its subsidiaries taken as a whole, or would materially and
              adversely affect the ability of Diamond Offshore to perform
              its obligations under the Amended Registration Rights
              Agreement or this Underwriting Agreement, or which are
              otherwise material in the context of the sale of the
              Underwritten Securities; and no such actions, suits or
              proceedings are, to Diamond Offshore's knowledge, threatened
              or contemplated.

                   (r)  The financial statements included in the Exchange
              Act Reports present fairly in all material respects the
              financial position of Diamond Offshore and its consolidated
              subsidiaries as of the dates shown and their results of
              operations and cash flows for the periods shown, and such
              financial statements have been prepared in conformity with
              generally accepted accounting principles in the United States
              applied on a consistent basis; any schedules included in the
              Exchange Act Reports present fairly the information required
              to be stated therein; and if pro forma financial statements
              are included in the Exchange Act Reports, the assumptions
              used in preparing the pro forma financial statements included
              in the Exchange Act Reports provide a reasonable basis for
              presenting the significant effects directly attributable to
              the transactions or events described therein, the related pro
              forma adjustments give appropriate effect to those
              assumptions in all material respects, and the pro forma
              columns therein reflect the proper application in all
              material respects of those adjustments to the corresponding
              historical financial statement amounts.

                   (s)  Except as disclosed in the Exchange Act Reports,
              since the date of the latest audited financial statements
              included in the Exchange Act Reports there has been no
              material adverse change, nor any development or event
              involving a prospective material adverse change, in the
              condition (financial or other), business, properties or 


                                        -11-





              results of operations of Diamond Offshore and its
              subsidiaries taken as a whole, and there has been no dividend
              or distribution of any kind declared, paid or made by Diamond
              Offshore on any class of its capital stock.

                   (t)  Diamond Offshore is not and, after giving effect to
              the transactions contemplated by this Underwriting Agreement,
              will not be (i) an "investment company" or a company
              "controlled" by an "investment company" within the meaning of
              the Investment Company Act of 1940, as amended, or (ii) a
              "holding company" or a "subsidiary company" or an "affiliate"
              of a holding company within the meaning of the Public Utility
              Holding Company Act of 1935, as amended.

                   (u)  Neither Diamond Offshore nor any of its affiliates
              does business with the government of Cuba or with any person
              or affiliate located in Cuba within the meaning of Section
              517.075, Florida Statutes.

                   (v)  No consent or approval of any federal governmental
              agency with respect to any federal maritime law matter is
              required in connection with performance by Diamond Offshore
              of its obligations under this Underwriting Agreement, and the
              execution, delivery, and performance by Diamond Offshore and
              the consummation of the transactions contemplated thereby
              will not violate any existing federal maritime laws,
              including, without limitation, the Shipping Act, 1916, as
              amended, and the rules and regulations of the Maritime
              Administration (MarAd) and the United States Coast Guard.

              2.  Purchase and Sale.  Subject to the terms and conditions
         and in reliance upon the representations and warranties set forth
         herein, the Company agrees to sell to each Underwriter, and each
         Underwriter agrees, severally and not jointly, to purchase from
         the Company, at the purchase price set forth in Schedule I hereto
         the principal amount of the Underwritten Securities set forth
         opposite such Underwriter's name in Schedule II hereto, except
         that, if Schedule I hereto provides for the sale of Securities
         pursuant to delayed delivery arrangements, the respective
         principal amounts of Underwritten Securities to be purchased by
         the Underwriters shall be as set forth in Schedule II hereto less
         the respective amounts of Contract Securities (as hereinafter
         defined) determined as provided below.  Securities to be purchased
         by the Underwriters are herein sometimes called the "Underwritten
         Securities" and Securities to be purchased pursuant to Delayed
         Delivery Contracts as hereinafter provided are herein called
         "Contract Securities."

              In addition, subject to the terms and conditions herein set
         forth, the Company may grant, if so provided in Schedule I, an
         option to the Underwriters, severally and not jointly, to purchase
         up to the number or aggregate principal amount, as the case may
         be, of the Option Underwritten Securities set forth therein at a
         price per Option Underwritten Security equal to the price per
         Initial Underwritten Security, less an amount equal to any
         dividends or distributions declared by the Company and paid or
         payable on the Initial Underwritten 


                                        -12-





         Securities but not payable on the Option Underwritten Securities.
         Such option, if granted, will expire 30 days after the date of
         this Underwriting Agreement, and may be exercised in whole or in
         part from time to time only for the purpose of covering over-
         allotments which may be made in connection with the offering and
         distribution of the Initial Underwritten Securities upon notice by
         the Representatives to the Company setting forth the number or
         aggregate principal amount, as the case may be, of Option
         Underwritten Securities as to which the several Underwriters are
         then exercising the option and the time, date and place of payment
         and delivery for such Option Underwritten Securities.  Any such
         time and date of payment and delivery shall be determined by the
         Representatives, but shall not be later than seven full business
         days after the exercise of said option, nor in any event prior to
         the Closing Date, unless otherwise agreed upon by the
         Representatives and the Company.  If the option is exercised as to
         all or any portion of the Option Underwritten Securities, each of
         the Underwriters, severally and not jointly, will purchase that
         amount which shall bear the same proportion to the total principal
         amount of Option Underwritten Securities as the principal amount
         of Securities set forth opposite the name of such Underwriter
         bears to the aggregate principal amount of Securities set forth in
         Schedule II hereto, except to the extent that you determine that
         such reduction shall be otherwise than in such proportion and so
         advise the Company in writing.

              If so provided in Schedule I hereto, the Underwriters are
         authorized to solicit offers to purchase Securities from the
         Company pursuant to delayed delivery contracts ("Delayed Delivery
         Contracts"), substantially in the form of Schedule III hereto but
         with such changes therein as the Company may authorize or approve.
         The Underwriters will endeavor to make such arrangements and, as
         compensation therefor, the Company will pay to the
         Representatives, for the account of the Underwriters, on the
         Closing Date, the percentage set forth in Schedule I hereto of the
         principal amount of the Securities for which Delayed Delivery
         Contracts are made.  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.  The Company will enter
         into Delayed Delivery Contracts in all cases where sales of
         Contract Securities arranged by the Underwriters have been
         approved by the Company but, except as the Company may otherwise
         agree, each such Delayed Delivery Contract must be for not less
         than the minimum principal amount set forth in Schedule I hereto
         and the aggregate principal amount of Contract Securities may not
         exceed the maximum aggregate principal amount set forth in
         Schedule I hereto.  The Underwriters will not have any
         responsibility in respect of the validity or performance of
         Delayed Delivery Contracts.  The principal amount of Securities to
         be purchased by each Underwriter as set forth in Schedule II
         hereto shall be reduced by an amount which shall bear the same
         proportion to the total principal amount of Contract Securities as
         the principal amount of Securities set forth opposite the name of
         such Underwriter bears to the aggregate principal amount of
         Securities set forth in Schedule II hereto, except to the extent
         that you determine that such reduction shall be otherwise than in
         such proportion and so advise the Company in writing; provided,
         however, that, subject to Section 9 hereof, the total principal
         amount of Securities to be purchased by all Underwriters shall be
         the aggregate principal 


                                        -13-





         amount of Securities set forth in Schedule II hereto less the
         aggregate principal amount of Contract Securities.

              3.  Delivery and Payment.  Delivery of and payment for the
         Underwritten Securities shall be made at the office, on the date
         and at the time specified in Schedule I hereto, which date and
         time may be postponed by agreement between the Representatives and
         the Company or as provided in Section 9 hereof (such date and time
         of delivery and payment for the Underwritten Securities being
         herein called the "Closing Date").  In addition, in the event that
         the Underwriters have exercised their option, if any, to purchase
         any or all of the Option Underwritten Securities, payment of the
         purchase price for, and delivery of such Option Underwritten
         Securities, shall be made at the location set forth on Schedule I,
         or at such other place as shall be agreed upon by the
         Representatives and the Company, as specified in the notice from
         the Representatives to the Company.

              Payment shall be made to the Company by wire transfer of
         immediately available funds to a bank account designated by the
         Company, against delivery to the Representatives for the
         respective accounts of the Underwriters of the Underwritten
         Securities to be purchased by them.  It is understood that each
         Underwriter has authorized the Representatives, for its account,
         to accept delivery of, receipt for, and make payment of the
         purchase price for, the Underwritten Securities which it has
         severally agreed to purchase.  The Representatives, individually
         and not as representative of the Underwriters, may (but shall not
         be obligated to) make payment of the purchase price for the
         Underwritten Securities to be purchased by any Underwriter whose
         funds have not been received by the Closing Date, as the case may
         be, but such payment shall not relieve such Underwriter from its
         obligations hereunder.

              Certificates for the Underwritten Securities shall be
         registered in such names and in such denominations as the
         Representatives may request not less than two full business days
         in advance of the Closing Date.  The Company agrees to have the
         Underwritten Securities available for inspection, checking and
         packaging by the Representatives in New York, New York, not later
         than 1:00 p.m. on the business day prior to the Closing Date.

              4.  Agreements.  (a)  The Company agrees with the several
         Underwriters that:

                   (i)  Until the earlier of (X) the termination of the
              offering of the Underwritten Securities, and (Y) six months
              from the date of this Underwriting Agreement, the Company
              will not file any amendment (other than amendments resulting
              from the filing of the documents incorporated by reference
              pursuant to Item 12 of Form S-3 under the Act) of the
              Registration Statement or the Final Prospectus unless the
              Company has furnished you a copy for your review prior to
              filing and will not file any such proposed amendment or
              supplement to which you reasonably object.  The Company will
              cause the Final Prospectus to be filed with the Commission
              pursuant to Rule 424.  The Company will promptly advise the
              Representatives (A) when the Final Prospectus shall have been
              filed with the Commission pursuant to 


                                        -14-





              Rule 424, (B) when any amendment to the Registration
              Statement relating to the Underwritten Securities shall have
              become effective, (C) of any request by the Commission for
              any amendment of the Registration Statement or amendment of
              or supplement to the Final Prospectus or for any additional
              information, (D) of the issuance by the Commission of any
              stop order suspending the effectiveness of the Registration
              Statement or the institution or threatening of any proceeding
              for that purpose and (E) of the receipt by the Company of any
              notification with respect to the suspension of the
              qualification of the Underwritten Securities for sale in any
              jurisdiction or the initiation or threatening of any
              proceeding for such purpose.  The Company will use its best
              efforts to prevent the issuance of any such stop order and,
              if issued, to obtain as soon as possible the withdrawal
              thereof.

                  (ii)  If, at any time when a prospectus relating to the
              Underwritten Securities is required to be delivered under the
              Act, any event occurs as a result of which, the Final
              Prospectus as then amended or supplemented would include any
              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 shall be necessary to amend or
              supplement the Final Prospectus to comply with the Act or the
              Exchange Act or the respective rules thereunder, the Company
              promptly will prepare and file with the Commission, subject
              to the first sentence of paragraph (a)(i) of this Section 4,
              an amendment or supplement which will correct such statement
              or omission or an amendment which will effect such
              compliance.

                 (iii)  The Company will comply with the Act and the Act
              Regulations and the Exchange Act and the Exchange Act
              Regulations so as to permit the completion of the
              distribution of the Underwritten Securities as contemplated
              in this Underwriting Agreement and in the Registration
              Statement and the Final Prospectus.  If at any time when the
              Final Prospectus is required by the Act or the Exchange Act
              to be delivered in connection with sales of the Underwritten
              Securities, any event shall occur or condition shall exist as
              a result of which it is necessary, in the opinion of counsel
              for the Underwriters or for the Company, to amend the
              Registration Statement in order that the Registration
              Statement will not contain an untrue statement of a material
              fact or omit to state a material fact required to be stated
              therein or necessary to make the statements therein not
              misleading or to amend or supplement the Final Prospectus in
              order that the Final Prospectus will not include an untrue
              statement of a material fact or omit to state a material fact
              necessary in order to make the statements therein not
              misleading in the light of the circumstances existing at the
              time it is delivered to a purchaser, or if it shall be
              necessary, in the opinion of such counsel, at any such time
              to amend the Registration Statement or amend or supplement
              the Final Prospectus in order to comply with the requirements
              of the Act or the Act Regulations, the Company will promptly
              prepare and file with the Commission, subject to Section
              4(a)(i), 


                                        -15-





              such amendment or supplement as may be necessary to correct
              such statement or omission or to make the Registration
              Statement or the Final Prospectus comply with such
              requirements, and the Company will furnish to the
              Underwriters, without charge, such number of copies of such
              amendment or supplement as the Underwriters may reasonably
              request.

                  (iv)  The Company will make generally available to its
              securityholders and to the Representatives not later than 90
              days after the end of the 12-month period beginning at the
              end of the current fiscal quarter of the Company an earnings
              statement or statements of the Company and its subsidiaries
              which will satisfy the provisions of Section 11(a) of the Act
              and Rule 158 under the Act.

                   (v)  The Company will furnish to the Representatives and
              counsel for the Underwriters, without charge, copies of the
              Registration Statement (including exhibits thereto or
              incorporated by reference therein and documents incorporated
              or deemed to be incorporated by reference therein), and each
              amendment to the Registration Statement which shall become
              effective on or prior to the Closing Date and, so long as
              delivery of a prospectus by an Underwriter or dealer may be
              required by the Act, as many copies of any Preliminary
              Prospectus and the Final Prospectus and any amendments
              thereof and supplements thereto as the Representatives may
              reasonably request and the Company hereby consents to the use
              of such copies for purposes permitted by the Act.  The
              Company will pay the expenses of printing or other production
              of all documents relating to the offering.  The Final
              Prospectus and copies of the Registration Statement and each
              amendment thereto furnished to the Underwriters will be
              identical to any electronically transmitted copies thereof
              filed with the Commission pursuant to EDGAR, except to the
              extent permitted by Regulation S-T.

                  (vi)  The Company will arrange for the qualification of
              the Underwritten Securities for sale under the laws of such
              jurisdictions as the Representatives may reasonably
              designate, will maintain such qualifications in effect so
              long as required for the distribution of the Underwritten
              Securities and will arrange for the determination of the
              legality of the Underwritten Securities for purchase by
              institutional investors; provided, however, the Company shall
              not be obligated to file any general consent to service of
              process under the laws of any such jurisdiction, subject

              issued in connection with an acquisition, merger or similar

              affiliate of the issuer, agrees to the foregoing lock-up
              restriction for the remainder of the 90-day period), except
              for the Underwritten Securities offered in connection with
              the offering.

                  (ix)  The Company will keep available at all times such

              enable the Company to satisfy its obligations under the terms
              of the Underwritten Securities.

                   (x)  The Company will use reasonable efforts to cause

              Act and the Exchange Act Regulations.

                 (iii)  During the period beginning from the date of the

              securities registered on Form S-4 issued in connection with
              an acquisition, merger or similar transaction, in which event
              an acquiror of such securities who is, or would by virtue of
              such acquisition be, an affiliate of the issuer, agrees to
              the foregoing lock-up restriction for the remainder of the

                   further as enforcement thereof may be limited by
                   governmental authority to limit, delay or prohibit the
                   making of payments outside the United States.  The

                   terms, except as the enforcement thereof may be limited
                   by bankruptcy, insolvency, reorganization, moratorium or
                   other similar laws relating to or affecting creditors'

                   Company;

                     (viii)  there is no pending or, to the best knowledge
                   of such counsel, threatened action, suit or proceeding
                   before any court or governmental agency, authority or
                   body or any arbitrator involving the Company or any of
                   its subsidiaries, of a character required to be
                   disclosed in the Registration Statement which is not
                   adequately disclosed in the Final Prospectus, and there
                   is no franchise, contract or other document of a
                   character required to be described in the Registration
                   Statement or Final Prospectus, or to be filed as an
                   exhibit, which is not described or filed as required;

                   Prospectus describing any legal proceedings or material
                   contracts or agreements relating to the Company fairly
                   summarize such matters in all material respects;

                       (ix)  the Registration Statement and any amendments
                   thereto have become effective under the Act; to the best
                   knowledge of such counsel, no stop order suspending the
                   effectiveness of the Registration Statement, as amended,
                   has been issued, no proceedings for that purpose have
                   been instituted or threatened, and the Registration
                   Statement, the Final Prospectus and each amendment
                   thereof or supplement thereto as of their respective
                   effective or issue dates (other than the financial
                   statements and other financial and statistical
                   information contained therein as to which such counsel
                   need express no opinion) complied as to form in all
                   material respects with the applicable requirements of
                   the Act and the Exchange Act and the respective rules
                   thereunder; and such counsel has no reason to believe
                   that the Registration Statement, or any amendment
                   thereof, at the time it became effective and at the date
                   of this Underwriting Agreement, contained any untrue
                   statement of a material fact or omitted to state any
                   material fact required to be stated therein or necessary
                   to make the statements therein not misleading or that
                   the Final Prospectus, as amended or supplemented, as of
                   its date and as of the date hereof, includes any untrue

                   fact necessary to make the statements therein, in light
                   of the circumstances under which they were made, not
                   misleading;

                       (xi)  no consent, approval, authorization or order
                   of any court or governmental agency or body is required
                   for the consummation by the Company of the transactions
                   contemplated herein or in the Delayed Delivery
                   Contracts, except such as have been obtained under the
                   Act and such as may be required under the blue sky laws
                   of any jurisdiction in connection with the purchase and
                   distribution of the Underwritten Securities by the
                   Underwriters and such other approvals (specified in such
                   opinion) as have been obtained;

                      (xii)  neither the issue and sale of the Underwritten
                   Securities, nor the consummation of any other of the
                   transactions herein contemplated nor the fulfillment of
                   the terms hereof or of any Delayed Delivery Contracts
                   will conflict with, result in a breach of, or constitute
                   a default under the Restated Certificate of
                   Incorporation or By-laws of the Company or the terms of
                   any indenture or other agreement or instrument known to
                   such counsel and to which the Company is a party or
                   bound, or any order or regulation known to such counsel
                   to be applicable to the Company of any court, regulatory
                   body, administrative agency, governmental body or
                   arbitrator having jurisdiction over the Company; and

                     (xiii)  the Company is not now, and upon the sale of
                   the Underwritten Securities to be sold by it hereunder
                   and application of the net proceeds from such sale as
                   described in the Final Prospectus under "Use of
                   Proceeds" will not be, an "investment company" within
                   the meaning of the Investment Company Act of 1940, as
                   amended.

              In rendering such opinion, such counsel may rely (A) as to
         matters involving the application of laws of any jurisdiction
         other than the corporate laws of the State of Delaware and the
         laws of the State of New York or the United States, to the extent
         deemed proper and specified in such opinion, upon the opinion of
         other counsel of good standing believed to be reliable and who are
         satisfactory to counsel for the Underwriters and (B) as to matters
         of fact, to the extent deemed proper, on certificates of
         responsible officers of the Company and public officials.

              (c)(I)  The Representatives shall have received an opinion,
         dated such Closing Date, of Weil, Gotshal & Manges LLP, counsel to
         Diamond Offshore, to the effect that:

                   (i)  Diamond Offshore is a corporation duly organized,
              validly existing and in 


                                        -22-





              good standing under the laws of the State of Delaware, and
              has all requisite corporate power and authority to own, lease
              and operate its properties and to carry on its business as
              described in the Final Prospectus;

                  (ii)  all of the outstanding shares of Diamond Offshore
              Common Stock (including the Underlying Securities) have been
              duly authorized and validly issued, are fully paid and non-
              assessable, are free of any preemptive rights pursuant to law
              or Diamond Offshore's Restated Certificate of Incorporation
              and conform as to legal matters in all material respects to
              the description thereof contained in the Final Prospectus;

                 (iii)  Diamond Offshore has all requisite corporate power
              and authority to execute and deliver each of the Underwriting
              Agreement and the Amended Registration Rights Agreement and
              to perform its obligations thereunder.  The execution,
              delivery and performance of each of the Underwriting
              Agreement and the Amended Registration Rights Agreement have
              been duly authorized by all necessary corporate action on the
              part of Diamond Offshore.  Each of the Underwriting Agreement
              and the Amended Registration Rights Agreement has been duly
              executed and delivered by Diamond Offshore;

                  (iv)  the execution, delivery and performance by Diamond
              Offshore of each of the Underwriting Agreement and the
              Amended Registration Rights Agreement and the compliance by
              Diamond Offshore with the provisions of each of the
              Underwriting Agreement and the Amended Registration Rights
              Agreement and the consummation of the transactions
              contemplated thereby will not conflict with, constitute a
              default under or result in a breach or violation of (a) any
              of the terms, conditions or provisions of the Restated
              Certificate of Incorporation or Amended By-Laws, as amended,
              of Diamond Offshore, (b) any New York, Texas, Delaware
              corporate or federal law or regulation (other than federal
              and state securities or blue sky laws, as to which such
              counsel need express no opinion in this sentence, and the
              Shipping Act, 1916, as amended, as to which such counsel need
              express no opinion), or (c) any judgment, writ, injunction,
              decree, order or ruling of any federal or state court or
              governmental authority binding on Diamond Offshore or any of
              it properties which remains unsatisfied and unperformed on
              the Closing Date and of which such counsel is aware, except
              in each case other than with respect to clause (a), any such
              conflict, default, breach or violation as would not impair
              Diamond Offshore's ability to perform its obligations under
              the Underwriting Agreement or the Amended Registration Rights
              Agreement or have any material adverse effect upon the
              consummation of the transactions contemplated by the
              Underwriting Agreement or the Amended Registration Rights
              Agreement;

                   (v)  no consent, approval, waiver, license, order or
              authorization or other 


                                        -23-





              action by or filing with any New York, Texas, Delaware
              corporate or federal governmental agency, body or court is
              required in connection with the execution and delivery by
              Diamond Offshore of the Underwriting Agreement or the Amended
              Registration Rights Agreement, or for the consummation by
              Diamond Offshore of the transactions contemplated thereby,
              except for filings and other action required pursuant to
              federal and state securities or blue sky laws, as to which
              such counsel need express no opinion, or the Shipping Act,
              1916, as amended, as to which such counsel need express no
              opinion, and those already obtained and made under the Act or
              the Delaware General Corporation Law ("DGCL");

                  (vi)  Diamond Offshore is not (A) an "investment company"
              or an entity "controlled" by an "investment company" under
              the Investment Company Act, as amended, and the rules and
              regulations promulgated by the Commission thereunder (the
              "Investment Company Act") or (B) a "holding company" or a
              "subsidiary company" or an "affiliate" of a holding company
              within the meaning of the Public Utility Holding Company Act
              of 1935, as amended, and the rules and regulations
              promulgated by the Commission thereunder (the "Holding
              Company Act") (in rendering such opinion, such counsel may
              assume that the Company (x) is not and is not controlled by
              an "investment company" under the Investment Company Act and
              (y) is not a "holding company" or a "subsidiary company" or
              an "affiliate" of a holding company under the Holding Company
              Act);

                 (vii)  the statements in the Final Prospectus under the
              caption "Description of Diamond Offshore Capital Stock",
              insofar as they constitute descriptions of Diamond Offshore
              Common Stock or refer to statements of laws or legal
              conclusions under the DGCL, constitute fair summaries thereof
              in all material respects.  The statements in the Final
              Prospectus under the caption "The Company and Relationship
              with Diamond Offshore", insofar as they constitute
              descriptions of the Amended Registration Rights Agreement,
              constitute fair summaries thereof in all material respects;

              In addition, such counsel shall state that such counsel has
         participated in conferences with officers and other
         representatives of the Company and Diamond Offshore, independent
         public accountants for Diamond Offshore, representatives of the
         Underwriters and representatives of counsel for the Underwriters,
         at which conferences the contents of the Registration Statement
         and the Final Prospectus and related matters were discussed, and,
         although such counsel has not independently verified and is not
         passing upon and assumes no responsibility for the accuracy,
         completeness or fairness of such statements contained in the
         Registration Statement or the Final Prospectus, such counsel shall
         advise you, on the basis of the foregoing that no facts have come
         to such counsel's attention which lead such counsel to believe
         that 


                                        -24-





         the Final Prospectus, as of the date of the Underwriting Agreement
         or as of such Closing Date contained or contains an untrue
         statement of a material fact or omitted to state any material fact
         necessary in order to make the statements therein, in the light of
         the circumstances under which they were made, not misleading (it
         being understood that such counsel need only express such views in
         respect of information relating to Diamond Offshore that is
         included in the Final Prospectus and need express no opinion as to
         the financial statements and related notes or the other financial,
         statistical and accounting data stated or omitted in the Final
         Prospectus);

              (c)(II)  The Representatives shall have received an opinion,
         dated such Closing Date, of the Vice President and General Counsel
         of Diamond Offshore, to the effect that:

                   (i)  Diamond Offshore is duly qualified to transact
              business as a foreign corporation in good standing in all
              jurisdictions other than the State of Delaware in which its
              ownership or lease of property or the conduct of its business
              requires such qualification, except those jurisdictions where
              the failure to be so qualified would not have a material
              adverse effect on the business, operations or financial
              condition of Diamond Offshore and its subsidiaries taken as a
              whole;

                  (ii)  all of the issued and outstanding shares of capital
              stock of each subsidiary of Diamond Offshore listed on
              Schedule III hereto (each, a "DO Subsidiary" and collectively
              the "DO Subsidiaries") are owned, directly or indirectly, of
              record and beneficially by Diamond Offshore, free and clear
              of all liens, claims, limitations on voting rights, options,
              security interests and other encumbrances and have been duly
              authorized, validly issued, and are fully paid and
              nonassessable, except to the extent that any such liens,
              claims, limitations, options, security interests and other
              encumbrances, individually or in the aggregate, would not
              have a material adverse effect on the business, operations or
              financial condition of Diamond Offshore and its subsidiaries,
              taken as a whole;

                 (iii)  each DO Subsidiary is a corporation, duly
              organized, validly existing and in good standing under the
              laws of its jurisdiction of incorporation.  Each DO
              Subsidiary is duly qualified to transact business and is in
              good standing as a foreign corporation in each state listed
              by such DO Subsidiary's name on Schedule III hereto, such
              states being the only states in which each DO Subsidiary is
              required to be qualified, except where the failure to be so
              qualified would not have a material adverse effect on the
              business, operations or financial condition of Diamond
              Offshore and its subsidiaries, taken as a whole;

                  (iv)  no consent or approval of any federal governmental
              agency with respect to any federal maritime law matter is
              required in connection with performance by Diamond Offshore
              of its obligations under the Underwriting Agreement or the
              Amended Registration Rights Agreement; and the execution,
              delivery, and 


                                        -25-





              performance by Diamond Offshore and the consummation of the
              transactions contemplated thereby will not violate any
              existing federal maritime laws, including, without
              limitation, the Shipping Act, 1916, as amended, and the rules
              and regulations of the Maritime Administration (MarAd) and
              the United States Coast Guard; and

                   (v)  there is no pending or, to the best knowledge of
              such counsel, threatened action, suit or proceeding before
              any court or governmental agency, authority or body or any
              arbitrator involving Diamond Offshore or any DO Subsidiary of
              a character required to be disclosed in the Registration
              Statement which is not adequately disclosed in the Final
              Prospectus; and the statements included or incorporated in
              the Final Prospectus describing any legal proceedings
              relating to Diamond Offshore fairly summarize such matters in
              all material respects.

              In rendering such opinion, such Vice President and General
         Counsel may rely as to the incorporation of Diamond Offshore, the
         authorization, execution and delivery of the Underwriting
         Agreement and the Amended Registration Rights Agreement and all
         other matters acceptable to the Representatives upon an opinion of
         counsel satisfactory to the Representatives, a copy of which shall
         be delivered concurrently with the opinion of such Vice President
         and General Counsel.

              The Representatives shall have also received an opinion,
         dated such Closing Date, of Nabarro Nathanson, special English
         counsel to Diamond Offshore, to the effect that each of Diamond
         Offshore Limited and Diamond Offshore (UK) Limited, each of which
         is a subsidiary of Diamond Offshore incorporated under the laws of
         the United Kingdom, (i) is duly incorporated and validly exists
         under the laws of England and Wales and (ii) has all requisite
         corporate power and authority to own, operate and lease its
         properties and to carry on its business as now carried on.

              (d)  The Representatives shall have received from each of
         Mayer, Brown & Platt, Andrews & Kurth L.L.P., and Sullivan &
         Cromwell, counsel for the Underwriters, such opinions, dated the
         Closing Date, with respect to the incorporation of the Company and
         of Diamond Offshore, the validity of the Indenture, the Securities
         and the Underlying Securities, the Registration Statement, the
         Final Prospectus and other related matters as the Representatives
         may reasonably require, and the Company and Diamond Offshore shall
         have furnished to such counsel such documents as they request for
         the purpose of enabling them to pass upon such matters.

              (e)  The Company shall have furnished to the Representatives
         a certificate of a Co-Chairman of the Board, the President or a
         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
         Registration Statement, the Final Prospectus and this Underwriting
         Agreement and that:


                                        -26-






                   (i)  the representations and warranties of the Company
              in this Underwriting 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)  no stop order suspending the effectiveness of the
              Registration Statement, as amended, has been issued and no
              proceedings for that purpose have been instituted or, to the
              Company's knowledge, threatened; and

                 (iii)  since the date of the most recent financial
              statements included in the Company's quarterly report on Form
              10-Q for the quarter ended June 30, 1997, there has been no
              Material Adverse Effect, except as set forth in the Final
              Prospectus.

              (f)  Diamond Offshore shall have furnished to the
         Representatives a certificate, dated the Closing Date, of the
         President, any Senior Vice President, the Treasurer or any Vice
         President and a principal financial or accounting officer of
         Diamond Offshore in which such officers, to the best of their
         knowledge after reasonable investigation, shall state that the
         representations and warranties of Diamond Offshore in this
         Underwriting Agreement are true and correct, that Diamond Offshore
         has complied with all agreements and satisfied all conditions on
         its part to be performed or satisfied hereunder at or prior to
         such Closing Date, and that, subsequent to the date of the most
         recent financial statements in the Exchange Act Reports, there has
         been no material adverse change, nor any development or event
         involving a prospective material adverse change, in the condition
         (financial or other), business, properties or results of
         operations of Diamond Offshore and its subsidiaries taken as a
         whole except as set forth in or contemplated by the Final
         Prospectus or as described in such certificate.

              (g)  At the Closing Date, the Company's independent
         accountants shall have furnished to the Representatives a letter
         or letters (which may refer to letters previously delivered to the
         Representatives), dated as of the Closing Date, in form and
         substance satisfactory to the Representatives, confirming that
         they are independent accountants within the meaning of the Act and
         the Exchange Act and the respective applicable published rules and
         regulations thereunder, that the response to Item 10 of the
         Registration Statement is correct insofar as it relates to them
         and stating in effect that:

                   (i)  in their opinion the audited financial statements
              and financial statement schedules included or incorporated in
              the Registration Statement and the Final Prospectus and
              reported on by them comply in form in all material respects
              with the applicable accounting requirements of the Act and
              the Exchange Act and the related published rules and
              regulations;

                  (ii)  on the basis of a reading of the amounts included
              or incorporated in the


                                        -27-





              Registration Statement and the Final Prospectus in response
              to Item 301 of Regulation S-K and of the latest unaudited
              financial statements made available by the Company and its
              subsidiaries; carrying out certain specified procedures (but
              not an examination in accordance with generally accepted
              auditing standards) which would not necessarily reveal
              matters of significance with respect to the comments set
              forth in such letter; a reading of the minutes of the
              meetings of the stockholders, directors and committees of the
              Company and the Subsidiaries; 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
              date of the most recent audited financial statements
              incorporated in the Registration Statement and the Final
              Prospectus, nothing came to their attention which caused them
              to believe that:

                        (1)  the amounts in the unaudited Selected
                   Consolidated Financial Data and Capitalization, if any,
                   included in the Registration Statement and the Final
                   Prospectus and the amounts included or incorporated in
                   the Registration Statement and the Final Prospectus in
                   response to Item 301 of Regulation S-K, do not agree
                   with the corresponding amounts in the audited financial
                   statements from which such amounts were derived;

                        (2)  any unaudited financial statements included or
                   incorporated in the Registration Statement and the Final
                   Prospectus do not comply as to form in all material
                   respects with applicable accounting requirements and
                   with the published rules and regulations of the
                   Commission with respect to financial statements included
                   or incorporated in quarterly reports on Form 10-Q under
                   the Exchange Act; and said unaudited financial
                   statements are not stated (except as permitted by Form
                   10-Q) in conformity with GAAP applied on a basis
                   substantially consistent with that of the audited
                   financial statements included or incorporated in the
                   Registration Statement and the Final Prospectus; or

                        (3)  with respect to the period subsequent to the
                   date of the most recent financial statements included or
                   incorporated in the Registration Statement and the Final
                   Prospectus, there were any changes, at a specified date
                   not more than five business days prior to the date of
                   the letter, in the long-term debt of the Company and its
                   subsidiaries or capital stock of the Company or
                   decreases in the stockholders' equity of the Company and
                   its subsidiaries as compared with the amounts shown on
                   the most recent consolidated balance sheet included or
                   incorporated in the Registration Statement and the Final
                   Prospectus, or for the period from the date of the most
                   recent financial statements included or incorporated in
                   the Registration Statement and the Final Prospectus to
                   such specified date there were any decreases, as
                   compared with the corresponding period in the preceding
                   year, in total revenues, or in total or per share
                   amounts of income before income taxes or of net income,
                   of the Company and its subsidiaries, except in all
                   instances for changes or decreases set forth in such
                   letter, in which 


                                        -28-





                   case the letter shall be accompanied by an explanation
                   by the Company as to the significance thereof unless
                   said explanation is not deemed necessary by the
                   Representatives; and

                 (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) set forth in the Registration Statement and the
              Final Prospectus and in Exhibit 12 to the Registration
              Statement, including the information included or incorporated
              in Items 1, 6, and 7 of the Company's annual report on Form
              10-K, incorporated in the Registration Statement and the
              Final Prospectus, or in "Management's Discussion and Analysis
              of Financial Condition and Results of Operations" included or
              incorporated in the Company's quarterly reports on Form 10-Q
              or in any Form 8-K, incorporated in the Registration
              Statement and the Final Prospectus, agrees with the
              accounting records of the Company and its subsidiaries,
              excluding any questions of legal interpretation.

              References to the Registration Statement and the Final
              Prospectus in this paragraph (g) are to such documents as
              amended and supplemented at the date of the letter.

              (h)  At the Closing Date, Diamond Offshore's independent
         accountants shall have furnished to the Representatives a letter
         or letters (which may refer to letters previously delivered to the
         Representatives), dated as of the Closing Date, with respect to
         such matters and in such form as the Representatives reasonably
         request.

              In addition, except as provided in Schedule I hereto, at the
         time this Underwriting Agreement is executed, each of the
         Company's and Diamond Offshore's independent public accountants
         shall have furnished to the Representatives a letter or letters,
         dated the date of this Underwriting Agreement, in form and
         substance satisfactory to the Representatives, to the effect set
         forth above in paragraphs (g) and (h) of this Section 7.

              (i)  Since the respective dates as of which information is
         given in the Final Prospectus as amended prior to the date of this
         Underwriting Agreement there shall not have been any change in the
         capital stock or long-term debt of the Company or Diamond Offshore
         or any of their respective subsidiaries or any change, or any
         development involving a prospective change, in or affecting the
         general affairs, management, financial position, stockholders'
         equity or results of operations of the Company, Diamond Offshore
         and their respective subsidiaries, otherwise than as set forth or
         contemplated in the Final Prospectus as amended prior to the date
         of this Underwriting Agreement, the effect of which is in the
         judgment of the Representatives so material and adverse as to make
         it impracticable or inadvisable to proceed with the public
         offering or the delivery of the Underwritten Securities on the
         terms and in the manner contemplated in the Final Prospectus as
         first amended or supplemented relating to the Underwritten
         Securities;


                                        -29-





              (j)  On or after the date of this Underwriting Agreement, no
         downgrading shall have occurred in the rating accorded the
         Company's or Diamond Offshore's debt securities or preferred stock
         by any "nationally recognized statistical rating organization", as
         that term is defined by the Commission for purposes of Rule
         436(g)(2) under the Act;

              (k)  On or after the date of this Underwriting Agreement
         there shall not have occurred any of the following: (i) a
         suspension or material limitation in trading in securities
         generally on the New York Stock Exchange; (ii) a suspension or
         material limitation in trading in the Company's or Diamond
         Offshore's securities on the New York Stock Exchange; (iii) a
         general moratorium on commercial banking activities declared by
         either Federal or New York State authorities; or (iv) the outbreak
         or escalation of hostilities involving the United States or the
         declaration by the United States of a national emergency or war,
         if the effect of any such event specified in this clause (iv) in
         the judgment of the Representatives makes it impracticable or
         inadvisable to proceed with the public offering or the delivery of
         the Underwritten Securities on the terms and in the manner
         contemplated in the Final Prospectus as first amended or
         supplemented relating to the Underwritten Securities;

              (l)  the Underwritten Securities shall have been approved for
         listing, subject only to official notice of issuance, on the New
         York Stock Exchange;

              (m)  the Amended Registration Rights Agreement shall have
         been duly executed and delivered by each of the Company and
         Diamond Offshore;

              (n)  In the event that the Underwriters are granted an over-
         allotment option by the Company and the Underwriters exercise
         their option to purchase all or any portion of the Option
         Underwritten Securities, the representations and warranties of the
         Company and of Diamond Offshore contained herein and the
         statements in any certificates furnished by the Company or Diamond
         Offshore hereunder shall be true and correct as of each Closing
         Date, and, at the relevant Closing Date, the Representatives shall
         have received:

                   (i)  A certificate, dated such Closing Date, of a Co-
              Chairman of the Board, the President or a Vice President of
              the Company and the principal financial officer or accounting
              officer of the Company, confirming that the certificate
              delivered at the Closing Date pursuant to Section 7(e) hereof
              remains true and correct as of such Closing Date.

                  (ii)  A certificate, dated such Closing Date, of the

              delivered at the Closing Date pursuant to Section 7(f) hereof
              remains true and correct as of such Closing Date.

              dated the Closing Date, relating to the Option Underwritten
              Securities and otherwise to the same effect as the opinion

              accountants, in form and substance satisfactory to the
              Representatives and dated such Closing Date, substantially in
              the same form and substance as the letter furnished to the
              Representatives pursuant to Section 7(g) hereof, except that
              the "specified date" on the letter furnished pursuant to this
              paragraph shall be a date not more than three business days
              prior to such Closing Date.

                (viii)  A letter from Diamond Offshore's independent
              accountants, in form and substance satisfactory to the
              Representatives and dated such Closing Date, substantially in

              the "specified date" on the letter furnished pursuant to this
              paragraph shall be a date not more than three business days
              prior to such Closing Date.

              (o)  Prior to the Closing Date, each of the Company and

              If any of the conditions specified in this Section 7 shall
         not have been fulfilled in all material respects when and as
         provided in this Underwriting Agreement, or if any of the opinions
         and certificates mentioned above or elsewhere in this Underwriting
         Agreement shall not be in all material respects reasonably
         satisfactory in form and substance to the 


                                        -31-





         Representatives and their counsel, this Underwriting Agreement and
         all obligations of the Underwriters hereunder may be canceled at,
         or at any time prior to, the Closing Date by the Representatives.
         Notice of such cancellation shall be given to the Company in
         writing or by telephone or telecopy confirmed in writing.

              8.  Reimbursement of Underwriters' Expenses.  If the sale of
         the Underwritten Securities provided for herein is not consummated
         because any condition to the obligations of the Underwriters set
         forth in Section 7 hereof is not satisfied, or because of any
         refusal, inability or failure on the part of the Company to
         perform any agreement herein or comply with any provision hereof
         other than by reason of a default by any of the Underwriters, or
         because of the termination of this Underwriting Agreement under
         Section 11, the Company will reimburse the Underwriters severally
         upon demand for all out-of-pocket expenses (including reasonable
         fees and disbursements of counsel) that shall have been incurred
         by them in connection with the proposed purchase and sale of the
         Underwritten Securities; such obligation of the Company to
         reimburse the Underwriters shall serve as the exclusive remedy of
         the Underwriters with respect to the Company.

              9.  Indemnification.  (a)  The Company will indemnify and
         hold harmless each Underwriter against any losses, claims, damages
         or liabilities, joint or several, to which such Underwriter may
         become subject, under the Act or otherwise, insofar as such
         losses, claims, damages or liabilities (or actions in respect
         thereof) arise out of or are based upon an untrue statement or
         alleged untrue statement of a material fact contained in any
         Preliminary Prospectus, any preliminary prospectus supplement, the
         Registration Statement, the Final Prospectus as amended or
         supplemented and any other prospectus relating to the Securities,
         or any amendment or supplement thereto, 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 will reimburse each
         Underwriter for any legal or other expenses reasonably incurred by
         such Underwriter in connection with investigating or defending any
         such action or claim as such expenses are incurred; provided,
         however, that the Company shall 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 an untrue statement or alleged untrue
         statement or omission or alleged omission made in any Preliminary
         Prospectus, any preliminary prospectus supplement, the
         Registration Statement, the Final Prospectus as amended or
         supplemented and any other prospectus relating to the Securities,
         or any such amendment or supplement in reliance upon and in
         conformity with written information furnished to the Company by
         any Underwriter of Underwritten Securities through the
         Representatives expressly for use in the Final Prospectus as
         amended or supplemented relating to such Securities.

              (b)  Diamond Offshore will indemnify and hold harmless each
         Underwriter against any losses, claims, damages or liabilities,
         joint or several, to which such Underwriter may become subject,
         under the Act or otherwise, insofar as such losses, claims,
         damages or liabilities (or actions in respect thereof) arise out
         of or are based upon an untrue statement or alleged untrue
         statement of a material fact contained in any Preliminary
         Prospectus, any preliminary 


                                        -32-





         prospectus supplement, the Registration Statement, the Final
         Prospectus as amended or supplemented and any other prospectus
         relating to the Securities, or any amendment or supplement
         thereto, 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, in each case to the extent, but only to the extent,
         that such untrue statement or alleged untrue statement or omission
         or alleged omission was made (i) in any Exchange Act Report that
         has been included in any current report on Form 8-K filed by the
         Company and (ii) under the headings "Diamond Offshore", "Price
         Range of Diamond Offshore Common Stock and Dividend Policy" and
         "Description of Diamond Offshore Capital Stock" in any Preliminary
         Prospectus, any preliminary prospectus supplement, the
         Registration Statement, the Final Prospectus as amended or
         supplemented and any other prospectus relating to the Securities,
         or any such amendment or supplement; and will reimburse each
         Underwriter for any legal or other expenses reasonably incurred by
         such Underwriter in connection with investigating or defending any
         such action or claim as such expenses are incurred.

              (c)  Each Underwriter will indemnify and hold harmless the
         Company against any losses, claims, damages or liabilities to
         which the Company may become subject, under the Act or otherwise,
         insofar as such losses, claims, damages or liabilities (or actions
         in respect thereof) arise out of or are based upon an untrue
         statement or alleged untrue statement of a material fact contained
         in any Preliminary Prospectus, any preliminary prospectus
         supplement, the Registration Statement, the Final Prospectus as
         amended or supplemented and any other prospectus relating to the
         Securities, or any amendment or supplement thereto, 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, in each case to the
         extent, but only to the extent, that such untrue statement or
         alleged untrue statement or omission or alleged omission was made
         in any Preliminary Prospectus, any preliminary prospectus
         supplement, the Registration Statement, the Final Prospectus as
         amended or supplemented and any other prospectus relating to the
         Securities, or any such amendment or supplement in reliance upon
         and in conformity with written information furnished to the
         Company by such Underwriter through the Representatives expressly
         for use therein; and will reimburse the Company for any legal or
         other expenses reasonably incurred by the Company in connection
         with investigating or defending any such action or claim as such
         expenses are incurred.

              (d)  Promptly after receipt by an indemnified party under
         subsection (a), (b) or (c) above of notice of the commencement of
         any action, such indemnified party shall, if a claim in respect
         thereof is to be made against the indemnifying party under such
         subsection, notify the indemnifying party in writing of the
         commencement thereof; but the omission so to notify the
         indemnifying party shall not relieve it from any liability which
         it may have to any indemnified party otherwise than under such
         subsection, except to the extent a defense or counterclaim has
         been foreclosed.  In case any such action shall be brought against
         any indemnified party and it shall notify the indemnifying party
         of the commencement thereof, the indemnifying party shall be
         entitled to participate therein and, to the extent that it
         determines, jointly with any other 


                                        -33-





         indemnifying party similarly notified, to assume the defense
         thereof, with counsel satisfactory to such indemnified party (who
         shall not, except with the consent of the indemnified party, be
         counsel to the indemnifying party), and, after notice from the
         indemnifying party to such indemnified party of its election so to
         assume the defense thereof, the indemnifying party shall not be
         liable to such indemnified party under such subsection for any
         legal expenses of other counsel or any other expenses, in each
         case subsequently incurred by such indemnified party, in
         connection with the defense thereof other than reasonable costs of
         investigation.  No indemnifying party shall, without the prior
         written consent of the indemnified party, effect the settlement or
         compromise of, or consent to the entry of any judgment with
         respect to, any pending or threatened action or claim in respect
         of which indemnification or contribution may be sought hereunder
         (whether or not the indemnified party is an actual or potential
         party to such action or claim) unless such settlement, compromise
         or judgment (i) includes an unconditional release of the
         indemnified party from all liability arising out of such action or
         claim and (ii) does not include a statement as to or an admission
         of fault, culpability or a failure to act, by or on behalf of any
         indemnified party.

              (e)  If the indemnification provided for in this Section 9 is
         unavailable to or insufficient to hold harmless an indemnified
         party under subsection (a), (b) or (c) above in respect of any
         losses, claims, damages or liabilities (or actions in respect
         thereof) referred to therein, then each indemnifying party shall
         contribute to the amount paid or payable by such indemnified party
         as a result of such losses, claims, damages or liabilities (or
         actions in respect thereof) in such several proportions as are
         appropriate to reflect the relative benefits received by each of
         the Company and Diamond Offshore, severally, on the one hand and
         the Underwriters of the Underwritten Securities on the other from
         the offering of the Underwritten Securities to which such loss,
         claim, damage or liability (or action in respect thereof) relates.
         If, however, the allocation provided by the immediately preceding
         sentence is not permitted by applicable law or if the indemnified
         party failed to give the notice required under subsection (d)
         above and a defense or counterclaim has been foreclosed, then each
         indemnifying party shall contribute to such amount paid or payable
         by such indemnified party in such proportion as is appropriate to
         reflect not only such relative benefits but also the relative
         fault of the Company and Diamond Offshore on the one hand and the
         Underwriters of the Underwritten Securities on the other in
         connection with the statements or omissions which resulted in such
         losses, claims, damages or liabilities (or actions in respect
         thereof), as well as any other relevant equitable considerations.
         The relative benefits received by the Company and Diamond
         Offshore, severally, on the one hand and such Underwriters on the
         other shall be deemed to be in the same proportion as the total
         net proceeds from such offering (before deducting expenses)
         received by each of the Company and Diamond Offshore, severally,
         bear to the total underwriting discounts and commissions received
         by such Underwriters.  The relative fault shall be determined by
         reference to, among other things, whether the untrue or alleged
         untrue statement of a material fact or the omission or alleged
         omission to state a material fact relates to information supplied
         by the Company and Diamond Offshore on the one hand or such
         Underwriters on the other and the parties' relative intent,
         knowledge, access to information and opportunity to correct or
         prevent such statement or omission.  The Company, Diamond Offshore
         and the Underwriters 


                                        -34-





         agree that it would not be just and equitable if contribution
         pursuant to this subsection (e) were determined by pro rata
         allocation (even if the Underwriters were treated as one entity
         for such purpose) or by any other method of allocation which does
         not take account of the equitable considerations referred to above
         in this subsection (e).  The amount paid or payable by an
         indemnified party as a result of the losses, claims, damages or
         liabilities (or actions in respect thereof) referred to above in
         this subsection (e) shall be deemed to include any legal or other
         expenses reasonably incurred by such indemnified party in
         connection with investigating or defending any such action or
         claim.  Notwithstanding the provisions of this subsection (e), no
         Underwriter shall be required to contribute any amount in excess
         of the amount by which the total price at which the applicable
         Underwritten Securities underwritten by it and distributed to the
         public were offered to the public exceeds the amount of any
         damages which such Underwriter has otherwise been required to pay
         by reason of such untrue or alleged untrue statement or omission
         or alleged omission.  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.  The obligations of
         the Underwriters of Underwritten Securities in this subsection (e)
         to contribute are several in proportion to their respective
         underwriting obligations with respect to such Securities and not
         joint.

              (f)  The obligations of the Company and Diamond Offshore
         under this Section 9 shall be in addition to any liability which
         the Company and Diamond Offshore may otherwise have and shall
         extend, upon the same terms and conditions, to each person, if
         any, who controls any Underwriter within the meaning of the Act;
         and the obligations of the Underwriters under this Section 9 shall
         be in addition to any liability which the respective Underwriters
         may otherwise have and shall extend, upon the same terms and
         conditions, to each officer and director of the Company and to
         each person, if any, who controls the Company within the meaning
         of the Act.

              10.  Default by an Underwriter.  If any one or more
         Underwriters shall fail to purchase and pay for any of the
         Underwritten Securities agreed to be purchased by such Underwriter
         or Underwriters hereunder and such failure to purchase shall
         constitute a default in the performance of its obligations under
         this Underwriting Agreement, the remaining Underwriters shall be
         obligated severally to take up and pay for (in the respective
         proportions which the amount of Underwritten Securities set forth
         opposite their names in Schedule II hereto bears to the aggregate
         amount of Underwritten Securities set forth opposite the names of
         all the remaining Underwriters) the Underwritten Securities which
         the defaulting Underwriter or Underwriters agreed but failed to
         purchase; provided, however, that in the event that the aggregate
         amount of Underwritten Securities which the defaulting Underwriter
         or Underwriters agreed but failed to purchase shall exceed 10% of
         the aggregate amount of Underwritten Securities set forth in
         Schedule II hereto, the remaining Underwriters shall have the
         right to purchase all, but shall not be under any obligation to
         purchase any, of the Underwritten Securities, and if such
         nondefaulting Underwriters do not purchase all the Underwritten
         Securities, this Underwriting Agreement will terminate without
         liability to any 


                                        -35-





         nondefaulting Underwriter or the Company.  In the event of a
         default by any Underwriter as set forth in this Section 10, the
         Closing Date shall be postponed for such period, not exceeding
         seven days, as the Representatives shall determine in order that
         the required changes in the Registration Statement and the Final
         Prospectus or in any other documents or arrangements may be
         effected.  Nothing contained in this Underwriting Agreement shall
         relieve any defaulting Underwriter of its liability, if any, to
         the Company and any nondefaulting Underwriter for damages
         occasioned by its default hereunder.

              11.  Termination and Liabilities.  (a)  This Underwriting
         Agreement shall be subject to termination in the absolute
         discretion of the Representatives, by notice given to the Company
         prior to delivery of and payment for the Underwritten Securities,
         if after the date of this Underwriting Agreement and prior to such
         time there has occurred a development or event of the kind
         specified in Section 7(i), 7(j) or 7(k).

              (b)  If this Underwriting Agreement is terminated pursuant to
         this Section 11, such termination shall be without liability of
         any party to any other party except as provided in Sections 6 and
         8 hereof, and provided further that Sections 1A, 1B, 9 and 12
         hereof shall survive such termination and remain in full force and
         effect.

              12.  Representations and Indemnities to Survive.  The
         respective agreements, representations, warranties, indemnities
         and other statements of the Company or its officers and of the
         Underwriters set forth in or made pursuant to this Underwriting
         Agreement will remain in full force and effect, regardless of any
         investigation made by or on behalf of any Underwriter or the
         Company or any of the officers, directors or controlling persons
         referred to in Section 9 hereof, and will survive delivery of and
         payment for the Underwritten Securities.

              13.  Notices.  All communications hereunder will be in
         writing and effective only on receipt, and, if sent to the
         Representatives, will be mailed, delivered, sent by or telegraphed
         and confirmed to them, at the address specified in Schedule I
         hereto; or, if sent to the Company, will be mailed, delivered or

         the benefit of and be binding upon the parties hereto and their
         respective successors and the officers and directors and
         controlling persons referred to in Section 8 hereof, and no other
         person will have any right or obligation hereunder.

              15.  Applicable Law.  This Underwriting Agreement will be
         governed by and construed in accordance with the laws of the State
         of New York.

              16.  Counterparts.  This Underwriting Agreement may be signed

                              PRELIMINARY STATEMENT

                   The Company and the Trustee have entered into an
         Indenture dated as of December 1, 1985 and a First and Second
         Supplemental Indenture thereto, each dated as of February 18,
         1997 (such Indenture, as supplemented is herein called the
         "Indenture").

                   Capitalized terms used but not otherwise defined
         herein, shall have the meanings given them in the Indenture.

                   Section 201 of the Indenture permits the form of the
         Debt Securities of any series to be established pursuant to an
         indenture supplemental to the Indenture.

                   Section 301 of the Indenture permits the terms of the
         Debt Securities of any series to be established in an indenture
         supplemental to the Indenture.

                   Section 901(6) of the Indenture provides that a
         supplemental indenture may be entered into by the Company and
         the Trustee without the consent of any Holders of Debt
         Securities to establish the form and terms of Debt Securities
         of any series as permitted by Sections 201 and 301.  In
         accordance with the terms of Sections 901(6) of the Indenture,
         the Company has, by Board Resolution, authorized this Third
         Supplemental Indenture.  The Trustee has determined that this
         Third Supplemental Indenture is in form satisfactory to it.

                   All things necessary to make this Third Supplemental
         Indenture a valid agreement of the Company and the Trustee and
         a valid amendment of and supplement to the Indenture have been
         done.

                   NOW, THEREFORE, THIS THIRD SUPPLEMENTAL INDENTURE
         WITNESSETH:

                   For and in consideration of the premises, it is

         Offshore is a party or the conveyance, transfer, sale or lease
         of all or substantially all of the properties and assets of
         Diamond Offshore, the Indenture shall be amended, without the
         consent of any Holders of Notes, so that this Note, if then
         Outstanding, will be exchangeable thereafter, during the period
         this Note shall be exchangeable as specified above, only into
         the kind and amount of securities, cash and other property
         receivable upon such consolidation, merger, conveyance,
         transfer, sale or lease (including any Diamond Offshore Common
         Stock retainable) by a holder of the number of shares of
         Diamond Offshore Common Stock into which this Note could have
         been exchanged immediately prior to such consolidation, merger,
         conveyance, transfer, sale or lease (assuming such holder of
         Diamond Offshore Common Stock failed to exercise any rights of
         election and received per share the kind and amount received
         per share by a plurality of non-electing shares and further
         assuming, if such consolidation, merger, conveyance, transfer,
         sale or lease is prior to October 1, 1998 that this Note was
         exchangeable immediately prior to the time of such occurrence
         at the initial Exchange Rate specified above as adjusted from
         the original issue date of the Notes to such time as provided
         in the Indenture).  No adjustment in the Exchange Rate will be
         made until such adjustment would require an increase or
         decrease of at least one percent of such rate, provided that
         any adjustment that would otherwise be made will be carried
         forward and taken into account in the computation of any
         subsequent adjustment.

                   The Company may at any time suspend the right of
         exchange attaching to the Notes, by giving one business day's
         notice of such suspension to the Trustee (which notice may be
         given by Diamond Offshore on behalf of the Company), provided
         that, (i) the total period during which such right of exchange
         is suspended shall not exceed 90 consecutive days at any one
         time or a total of 120 days in any 12-month period; and (ii) no
         such suspension may be in effect during the 14-day period
         preceding any Redemption Date or the final maturity date of the
         Notes.  In addition, the right of Holders to exchange will be
         suspended if the Company has irrevocably elected to pay in cash
         the Average Market Value Amount in respect of all Notes
         delivered for exchange prior to a Redemption Date or the final
         maturity date in respect of the Notes.

                   At any time prior to September 2, 2007, and unless
         the Company shall have previously elected in connection with a
         call for redemption or at maturity to pay in cash the Average
         Market Value Amount upon any exchange prior to the applicable
         Redemption Date or final maturity date, as set forth below, the
         Company may elect to make a cash settlement in respect of any
         Note surrendered for exchange by delivering notice thereof to
         the tendering Holder not more than five Trading Days after such
         Note is surrendered for exchange.  Such cash settlement shall
         be in an amount, per $1,000 principal amount of Notes delivered
         for exchange, equal to the greater of (A) $1,000 and (B) the
         product of (i) the then-prevailing Exchange Rate and (ii) the
         average of the Closing Price of the Diamond Offshore Common
         Stock on the five Trading Days commencing two Trading Days
         after delivery by the Company of such notice to such Holder.
         The Company will pay such cash settlement amount as promptly as
         practicable


                                       -8-




         after the completion of such five Trading Day period.

                   The Company may elect, in connection with a
         redemption of Notes or the final maturity of the Notes, to
         satisfy its obligations to Holders who elect to exchange their
         Notes for Diamond Offshore Common Stock by cash payment of the
         Average Market Value Amount.  If the Company makes such an
         election, Holders of Notes will no longer be entitled to
         receive Diamond Offshore Common Stock in exchange for their
         Notes.  The Company may make such an election, in respect of
         any Notes to be redeemed on a Redemption Date or repaid on the
         final maturity date, by giving an irrevocable notice thereof to
         the Holders not later than the 35th Trading Day prior to such
         Redemption Date or final maturity date, in which case the
         Company will be obligated to pay the Average Market Value
         Amount in respect of all Notes to be redeemed or repaid on such
         Redemption Date or final maturity date to Holders who elect to
         exchange their Notes for Diamond Offshore Common Stock.  If
         such notice is delivered in connection with a Redemption Date,
         it shall be required to be given not later than 35 Trading Days
         prior to the Redemption Date.

                   [IF NOT A GLOBAL SECURITY INSERT -- In the event of
         redemption or exchange of this Note in part only, a new Note or
         Notes for the unredeemed or unexchanged portion hereof will be
         issued in the name of the Holder hereof.]

                   [IF A GLOBAL SECURITY INSERT -- In the event of a
         deposit or withdrawal of an interest in this Note (including
         upon an exchange, transfer, redemption or exchange of this Note
         in part only), the Security Registrar, upon receipt of notice
         of such event from the Depositary's custodian for this Note,
         shall make an adjustment on its records to reflect an increase
         or decrease of the Outstanding principal amount of this Note
         resulting from such deposit or withdrawal, as the case may be.]

                   The indebtedness evidenced by this Note is, to the
         extent and in the manner provided in the Indenture, subordinate
         and subject in right of payment to the prior payment in full of
         all Senior Indebtedness of the Company, and this Note is issued
         subject to such provisions of the Indenture with respect
         thereto.  Each Holder of this Note, by accepting the same, (a)
         agrees to and shall be bound by such provisions, (b) authorizes
         and directs the Trustee on his behalf to take such action as
         may be necessary or appropriate to effectuate the subordination
         so provided and (c) appoints the Trustee his attorney-in-fact
         for any and all such purposes.

                   If an Event of Default shall occur and be continuing,
         the principal of all the Notes may be declared due and payable
         in the manner and with the effect provided in the Indenture.

                   The Indenture permits, with certain exceptions as
         therein provided, the amendment thereof and the modification of
         the rights and obligations of the Company and the rights under
         the Indenture of the Holders of Debt Securities issued
         thereunder at any time by the


                                       -9-




         Company and the Trustee with the consent of the Holders of a
         majority in principal amount of the Outstanding Debt Securities
         affected thereby.  The Indenture also contains provisions
         permitting the Holders of specified percentages in principal
         amount of the Notes at the time Outstanding, on behalf of the
         Holders of all the Notes, to waive compliance by the Company
         with certain provisions of the Indenture and certain past
         defaults under the Indenture and their consequences.  Any such
         consent or waiver by the Holder of this Note shall be
         conclusive and binding upon such Holder and upon all future
         Holders of this Note and of any Note issued in exchange herefor
         or in lieu hereof, whether or not notation of such consent or
         waiver is made upon this Note or such other Note.

                   No reference herein to the Indenture and no provision
         of this Note or of the Indenture shall alter or impair the
         obligation of the Company, which is absolute and unconditional,
         to pay the principal of and premium, if any, and interest on
         this Note at the times, places and rate, and in the coin or
         currency, herein prescribed or to exchange this Note for
         Diamond Offshore Common Stock or cash as and when provided in
         the Indenture.

                   As provided in the Indenture and subject to certain
         limitations therein set forth, the transfer of Notes is
         registrable on the Note Register upon surrender of a Note for
         registration of transfer at the office or agency of the Company
         in the Borough of Manhattan, The City of New York, and at such
         other offices or agencies as the Company may designate, duly
         endorsed by, or accompanied by a written instrument of transfer
         in form satisfactory to the Company and the Security Registrar
         duly executed by, the Holder thereof or his attorney duly
         authorized in writing, and thereupon one or more new Notes, of
         authorized denominations and for the same aggregate principal
         amount, will be issued to the designated transferee or
         transferees.

                   The Notes are issuable only in registered form
         without coupons in denominations of $1,000 and any integral
         multiple thereof.  As provided in the Indenture and subject to
         certain limitations therein set forth, Notes are exchangeable
         for a like aggregate principal amount of Notes of a different
         authorized denomination, as requested by the Holder
         surrendering the same.

                   No service charge shall be made for any such
         registration of transfer or exchange, but the Company may
         require payment of a sum sufficient to recover any tax or other
         governmental charge payable in connection therewith.

                   Prior to due presentation of a Security for
         registration of transfer, the Company, the Trustee and any
         agent of the Company or the Trustee may treat the Person in
         whose name such Note is registered, as the owner thereof for
         all purposes, whether or not such Note be overdue, and neither
         the Company, the Trustee nor any such agent shall be affected
         by notice to the contrary.

                   THE INDENTURE AND THIS NOTE SHALL BE GOVERNED BY AND
         CONSTRUED IN

                   3.  Title and Terms.

                   There shall be a series of Debt Securities designated
         as the "3_% Exchangeable Subordinated Notes due 2007" of the
         Company.  Their Stated Maturity shall be September 15, 2007 and
         they shall bear interest at the rate of 3_% per annum, from
         September 19, 1997 or from the most recent Interest Payment
         Date to which interest has been paid or duly provided for, as
         the case may be, payable semi-annually on March 15 and
         September 15, commencing March 15, 1998 until the principal
         thereof is paid or made available for payment.  The interest so
         payable, and punctually paid or duly provided for, on any
         Interest Payment Date will be paid to the Person in whose name
         the Notes (or one or more Predecessor Securities) are registered
         at the close of business on the Regular Record Date for such
         interest, which shall be the March 1 or






                                       -12-




         September 1 (whether or not a Business Day), as the case may
         be, next preceding such Interest Payment Date.

                   The aggregate principal amount of Notes which may be
         authenticated and delivered under this Third Supplemental
         Indenture is limited to $1,150,000,000, except for Notes
         authenticated and delivered upon registration or transfer of,
         or in exchange for, or in lieu of, other Notes pursuant to
         Section 304, 305, 306, 906 or 1107 of the Indenture.

                   The Notes shall be redeemable at the option of the
         Company and exchangeable into shares of Diamond Offshore Common
         Stock at the option of the Holder, subject to the Company's
         right to suspend exchanges and to elect cash settlement
         (including by payment of the Average Market Value Amount in
         connection with a redemption of Notes or final maturity of the
         Notes), in each case in accordance with the terms set forth in
         the form of Note and in this Third Supplemental Indenture.

                   The Securities of this series shall not be subject to
         a sinking fund.

                   The Notes of this series are not subject to
         defeasance at the option of the Company pursuant to Article
         Fifteen of the Indenture.

                   4.  Exchange of Notes.

                   4.1  Exchange Privilege and Exchange Rate; Suspension
         of Exchanges; Cash Settlement.

                   Subject to and upon compliance with the provisions of
         this Section, at the option of the Holder thereof, any Note or
         any portion which is $1,000 or an integral multiple thereof may
         be exchanged into fully paid and nonassessable shares
         (calculated as to each exchange to the nearest 1/100th of a
         share) of Diamond Offshore Common Stock at the Exchange Rate,
         determined as hereinafter provided, in effect at the time of
         exchange.  Such exchange right shall commence on October 1,
         1998 and shall expire at the close of business on September 15,
         2007.  In case a Note or portion thereof is called for
         redemption at the election of the Company, such exchange right
         in respect of the Note, or portion thereof, so called shall
         expire at the close of business on the Redemption Date unless
         the Company defaults in making the payment due upon redemption.

                   The rate at which shares of Common Stock shall be
         delivered upon exchange (herein called the "Exchange Rate")
         shall be initially 15.3757 shares of Diamond Offshore Common
         Stock for each $1,000 principal amount of Notes.  The Exchange
         Rate shall be adjusted in certain instances as provided in this
         Section 4.

                   The Company may at any time suspend the right of
         exchange attaching to the



                                       -13-




         Notes, by giving one business day's notice of such suspension
         to the Trustee (which notice may be given by Diamond Offshore
         on behalf of the Company), provided that, (i) the total period
         during which such right of exchange is suspended shall not
         exceed 90 consecutive days at any one time or a total of 120
         days in any 12-month period; and (ii) no such suspension may be
         in effect during the 14-day period preceding any Redemption
         Date or the final maturity date of the Notes.  In addition, the
         right of Holders to exchange will be suspended if  the Company
         has irrevocably elected to pay in cash the Average Market Value
         Amount in respect of all Notes delivered for exchange prior to
         Redemption Date or final maturity date in respect of the Notes,
         as provided in the Notes.

                   At any time prior to September 2, 2007, and unless
         the Company shall have previously elected in connection with a
         call for redemption or at maturity to pay in cash the Average
         Market Value Amount upon any exchange prior to the applicable
         Redemption Date or final maturity date, as set forth below, the
         Company may elect to make a cash settlement in respect of any
         Note surrendered for exchange by delivering notice thereof to
         the tendering Holder not more than five Trading Days after such
         Note is surrendered for exchange.  Such cash settlement shall
         be in an amount, per $1,000 principal amount of Notes delivered
         for  exchange, equal to the greater of (A) $1,000 and (B) the
         product of (i) the then-prevailing Exchange Rate and (ii) the
         average of the Closing Price of the Diamond Offshore Common
         Stock on the five Trading Days commencing two Trading Days
         after delivery by the Company of such notice to such Holder.
         The Company will pay such cash settlement amount as promptly as
         practicable after the completion of such five Trading Day
         period.

                   4.2.  Exercise of Exchange Privilege.

                   In order to exercise the exchange privilege, the
         Holder of any Note to be exchanged shall surrender such Note,
         duly endorsed or assigned to the Company or in blank, at any
         office or agency of the Company maintained for that purpose
         pursuant to Section 4.7 of this Third Supplemental Indenture,
         accompanied by a duly signed exchange notice substantially in
         the form provided in Section 2.5 of this Third Supplemental
         Indenture, stating that the Holder elects to exchange such Note
         or, if less than the entire principal amount thereof is to be
         exchanged, the portion thereof to be exchanged.  Each Note
         surrendered for exchange (in whole or in part) during the
         period from the close of business on any Regular Record Date
         next preceding any Interest Payment Date to the opening of
         business on such Interest Payment Date shall (except in the
         case of any Note or portion thereof which has been called for
         redemption on a Redemption Date occurring within such period)
         be accompanied by payment in New York Clearing House (next day)
         funds (or other funds acceptable to the Company) of an amount
         equal to the interest payable on such Interest Payment Date on
         the principal amount of such Note (or portion thereof, as the
         case may be) being surrendered for exchange.  The interest so
         payable on any Interest Payment Date with respect to any Note
         (or portion thereof, if applicable) which has been called for
         redemption on a Redemption Date occurring during the period
         from the close of


                                       -14-




         business on the Regular Record Date next preceding such
         Interest Payment Date to the opening of business on such
         Interest Payment Date, which Note (or portion thereof, if
         applicable) so called for redemption is surrendered for
         exchange (in whole or in part) prior to such Redemption Date, 
         shall be paid upon such exchange to the Holder of such Note 
         (or portion thereof) as of the exchange date in an amount 
         equal to the interest that would have been payable on the 
         principal amount of such Note (or portion thereof) so called 
         for redemption and being exchanged if such principal amount 
         had been exchanged as of the close of business on such Interest 
         Payment Date.  The interest so payable on any Interest Payment 
         Date in respect of any Note (or portion thereof, as the case 
         may be) which has not been called for redemption on a Redemption 
         Date occurring during the period from the close of business on 
         the Regular Record Date next preceding such Interest Payment Date 
         to the opening of business on such Interest Payment Date, which 
         Note (or portion thereof, as the case may be) not so called for 
         redemption is surrendered for exchange (in whole or in part) 
         during such period, shall be paid to the Holder of such Note as 
         of such Regular Record Date.  Interest payable on any Interest 
         Payment Date in respect of any Note surrendered for exchange on 
         or after such Interest Payment Date shall be paid to the Holder 
         of such Note as of the Regular Record Date next preceding such 
         Interest Payment Date, notwithstanding the exercise of the right 
         of exchange.  Except as provided in this paragraph, no cash payment 
         or adjustment shall be made upon any exchange on account of any 
         interest accrued from the Interest Payment Date next preceding the
         exchange date in respect of any Note (or part thereof, as the
         case may be) surrendered for exchange, or on account of any
         dividends on the Diamond Offshore Common Stock issued upon
         exchange.

                   Notes shall be deemed to have been exchanged
         immediately prior to the close of business on the day of
         surrender of such Notes for exchange in accordance with the
         foregoing provisions, and at such time the rights of the
         Holders of such Notes as Holders shall cease, and the Person or
         Persons entitled to receive the Diamond Offshore Common Stock
         issuable upon exchange shall be treated for all purposes as the
         record holder or holders of such Diamond Offshore Common Stock
         at such time.  Within five Trading Days of the exchange date,
         the Company shall issue and deliver to the Trustee, for
         delivery to the Holder, a certificate or certificates for the
         number of full shares of Diamond Offshore Common Stock issuable
         upon exchange, together with payment in lieu of any fraction of
         a share, if any, as provided in Section 4.3 of this Third 
         Supplemental Indenture.

                   In the case of any Note which is exchanged in part
         only, upon such exchange the Company shall execute and the
         Trustee shall authenticate and deliver to the Holder thereof,
         at the expense of the Company, a new Note or Notes of
         authorized denominations in an aggregate principal amount equal
         to the unexchanged portion of the principal amount of such
         Note.

                   4.3.  Fractions of Shares.

                   No fractional shares of Diamond Offshore Common Stock
         shall be delivered upon


                                       -15-




         exchange of any Note or Notes.  If more than one Note shall be
         surrendered for exchange at one time by the same Holder, the
         number of full shares which shall be issuable upon exchange
         thereof shall be computed on the basis of the aggregate
         principal amount of the Notes (or specified portions thereof)
         so surrendered.  Instead of any fractional share of Diamond
         Offshore Common Stock which would otherwise be issuable upon
         exchange of any Note or Notes (or specified portions thereof),
         the Company shall calculate and pay a cash adjustment in
         respect of such fraction (calculated to the nearest 1/100th of
         a share) in an amount equal to the same fraction of the Closing
         Price at the close of business on the day of exchange (or, if
         such day is not a Trading Day, on the Trading Day immediately
         preceding such day), or at the Company's option, the Company 
         shall round up to the next higher whole share.
                   4.4.  Adjustment of Exchange Rate.

                   The Exchange Rate shall be subject to adjustments
         from time to time as follows:

                   (1)  In case Diamond Offshore shall pay or make a 
         dividend or other distribution on Diamond Offshore Common Stock
         exclusively in Diamond Offshore Common Stock or shall pay or make 
         a dividend or other distribution on any other class of capital 
         stock of Diamond Offshore which dividend or distribution includes
         Diamond Offshore Common Stock, the Exchange Rate in effect at the 
         opening of business on the day next following the Determination Date 
         of such dividend or other distribution shall be increased by dividing 
         such Exchange Rate by a fraction of which the numerator shall be the
         number of shares of Diamond Offshore Common Stock outstanding
         at the close of business on such Determination Date and the
         denominator shall be the sum of such number of shares and the
         total number of shares constituting such dividend or other
         distribution, such increase to become effective immediately
         after the opening of business on the day next following such
         Determination Date.  For the purposes of this paragraph (1),
         the number of shares of Diamond Offshore Common Stock at any
         time outstanding shall not include shares held in the treasury
         of Diamond Offshore but shall include shares issuable in
         respect of scrip certificates issued in lieu of fractions of
         shares of Diamond Offshore Common Stock.  

                   (2)  Subject to the last sentence of paragraph (8) of
         this Section, in case  Diamond Offshore shall pay  or make a
         dividend or other distribution on Diamond Offshore Common Stock
         consisting exclusively of, or shall otherwise issue to all holders
         of Diamond Offshore Common Stock, rights, warrants or options
         entitling the holders thereof to subscribe for or purchase shares 
         of Diamond Offshore Common Stock at a price per share less than the
         current market price per share (determined as provided in
         paragraph (7) of this Section 4.4) of the Diamond Offshore
         Common Stock on the Determination Date, the Exchange Rate in effect 
         at the opening of business on the day following such Determination 
         Date shall be increased by dividing such Exchange Rate by a fraction 
         of which the numerator shall be the number of shares of Diamond 
         Offshore Common Stock outstanding at the close of business on such
         Determination Date plus the number of shares of Diamond
         Offshore Common Stock which the aggregate of the



                                       -16-




         offering price of the total number of shares of Diamond
         Offshore Common Stock so offered for subscription or purchase
         would purchase at such current market price and the denominator
         shall be the number of shares of Diamond Offshore Common Stock
         outstanding at the close of business on such Determination Date
         plus the number of shares of Diamond Offshore Common Stock so
         offered for subscription or purchase, such increase to become
         effective immediately after the opening of business on the day
         following such Determination Date.  For the purposes of this
         paragraph (2), the number of shares of Diamond Offshore Common
         Stock at any time outstanding shall not include shares held in
         the treasury of Diamond Offshore but shall include shares
         issuable in respect of scrip certificates issued in lieu of
         fractions of shares of Diamond Offshore Common Stock. 

                   (3)  In case outstanding shares of Diamond Offshore
         Common Stock shall be subdivided into a greater number of
         shares of Diamond Offshore Common Stock, the Exchange Rate in
         effect at the opening of business on the day following the day
         upon which such subdivision becomes effective shall be
         proportionately increased, and, conversely, in case outstanding
         shares of Diamond Offshore Common Stock shall each be combined
         into a smaller number of shares of Diamond Offshore Common
         Stock, the Exchange Rate in effect at the opening of business
         on the day following the day upon which such combination
         becomes effective shall be proportionately reduced, such
         increase or reduction, as the case may be, to become effective
         immediately after the opening of business on the day following
         the day upon which such subdivision or combination becomes
         effective.

                   (4)  Subject to the last sentence of this paragraph (4) 
         and to the last sentence of paragraph (8) of this Section, in case 
         Diamond Offshore shall, by dividend or otherwise, distribute to all 
         holders of Diamond Offshore Common Stock evidences of its 
         indebtedness, shares of any class of capital stock, securities, 
         cash or property (excluding any rights, warrants or options referred 
         to in paragraph (2) of this Section 4.4, any dividend or distribution 
         paid exclusively in cash and any dividend or distribution referred to 
         in paragraph (1) of this Section 4.4), the Exchange Rate shall be
         increased so that the same shall equal the rate determined by
         dividing the Exchange Rate in effect immediately prior to the
         effectiveness of the Exchange Rate increase contemplated by
         this paragraph (4) by a fraction of which the numerator shall
         be the current market price per share (determined as provided
         in paragraph (7) of this Section) of the Diamond Offshore
         Common Stock on the date of such effectiveness less the fair
         market value (as determined in good faith by the Board of
         Directors, whose determination shall be conclusive and
         described in a Board Resolution and shall, in the case of
         securities being distributed for which prior thereto there is
         an actual or when-issued trading market, be no less than the
         value determined by reference to the average of the closing
         prices in such market over the period specified in the
         succeeding sentence), on the date of such effectiveness, of the
         portion of the evidences of indebtedness, shares of capital
         stock, securities, cash and property so distributed applicable
         to one share of Diamond Offshore Common Stock and the
         denominator shall be such current market price per share of the
         Diamond Offshore Common Stock, such increase to become


                                       -17-




         effective immediately prior to the opening of business on the
         day next following the later of (a) the date fixed for the
         payment of such distribution and (b) the date 20 days after the
         notice relating to such distribution is given pursuant to
         Section 4.6 (such later date of (a) and (b) being referred to
         as the "Reference Date").  For purposes of this paragraph (4),
         any dividend or distribution that includes shares of Diamond
         Offshore Common Stock or rights, warrants or options to
         subscribe for or purchase shares of Diamond Offshore Common
         stock shall be deemed instead to be (a) a dividend or
         distribution of the evidences of indebtedness, cash, property,
         shares of capital stock or securities other than such shares of
         Diamond Offshore Common Stock or such rights, warrants or
         options (making any Exchange Rate increase required by this
         paragraph (4)) immediately followed by (b) a dividend or
         distribution of such shares of Diamond Offshore Common Stock or
         such rights, warrants or options (making any further Exchange
         Rate increase required by paragraph (1) or (2) of this Section
         4.4, except (i) the Reference Date of such dividend or
         distribution as defined in this paragraph (4) shall be
         substituted as "the date fixed for the determination of
         stockholders entitled to receive such dividend or other
         distribution", "the date fixed for the determination of
         stockholders entitled to receive such rights, warrants or
         options" and "the date fixed for such determination" within the
         meaning of paragraphs (1) and (2) of this Section 4.4 and (ii)
         any shares of Diamond Offshore Common Stock included in such
         dividend or distribution shall not be deemed "outstanding at
         the close of business on the date fixed for such determination"
         within the meaning of paragraph (1) of this Section 4.4).

                   (5)  In case Diamond Offshore shall, by dividend or
         otherwise, make a Cash Distribution in an aggregate amount
         that, combined together with (i) the aggregate amount of any
         other Cash Distributions made within the 12 months preceding
         the date of payment of such distribution in respect of which no
         adjustment pursuant to this paragraph (5) has been made and
         (ii) any Excess Purchase Payment made within the 12 months
         preceding the date of such distribution and in respect of which
         no adjustment has been made pursuant to paragraph (6) of this
         Section 4.4, exceeds 12.5% of Diamond Offshore's Common Stock
         Market Capitalization on the Determination Date for such Cash
         Distribution, then, and in each such case, immediately after
         the close of business on the Determination Date for such Cash
         Distribution, the Exchange Rate shall be adjusted so that the
         same shall equal the rate determined by dividing the Exchange
         Rate in effect immediately prior to the close of business on
         such Determination Date by a fraction (a) the numerator of
         which shall be equal to the current market price per share
         (determined as provided in paragraph (7) of this Section) of
         the Diamond Offshore Common Stock on such Determination Date
         less an amount equal to the quotient of (1) the amount of such
         excess (over 12.5% of Diamond Offshore's Common Stock Market 
         Capitalization as described above) divided by (2) the number 
         of shares of Diamond Offshore Common Stock outstanding on such 
         Determination Date and (b) the denominator of which shall be 
         equal to the current market price per share (determined as 
         provided in paragraph (7) of this Section 4.4) of the Diamond 
         Offshore Common Stock on such Determination Date.

                   (6)  In case Diamond Offshore or any subsidiary of
         Diamond Offshore shall make


                                       -18-




         an Excess Purchase Payment in an aggregate amount that,
         combined together with (i) the aggregate amount of any other
         Excess Purchase Payments made by Diamond Offshore or any
         subsidiary of Diamond Offshore within the 12 months preceding
         such Excess Purchase Payment in respect of which no adjustment
         pursuant to this paragraph (6) has been made and (ii) the
         aggregate amount of any Cash Distributions made within the 12
         months preceding such Excess Purchase Payment in respect of
         which no adjustment pursuant to paragraph (5) of this Section
         4.4 has been made, exceeds 12.5% of Diamond Offshore's Market
         Capitalization as of the Determination Date, then, and in each
         such case, immediately prior to the opening of business on the
         day after the tender offer in respect of which such Excess
         Purchase Payment is to be made expires, the Exchange Rate shall
         be adjusted so that the same shall equal the rate determined by
         dividing the Exchange Rate in effect immediately prior to the
         close of business on the Determination Date for such tender
         offer by a fraction (a) the numerator of which shall be equal
         to (A) the product of (I) the number of shares of Diamond
         Offshore Common Stock outstanding (including any tendered
         shares) at such Determination Date multiplied by (II) the
         current market price per share (determined as provided in
         paragraph (7) of this Section) of the Diamond Offshore Common
         Stock less (B) the amount of such excess (over 12.5% of Diamond
         Offshore's Common Stock Market Capitalization as described above)
         and (b) the denominator of which shall be equal to the product of 
         (X) the current market price per share of the Diamond Offshore 
         Common Stock (determined as provided in paragraph (7) of this 
         Section 4.4) as of such Determination Date multiplied by (Y) the 
         number of shares of Diamond Offshore Common Stock outstanding
         (including any tendered shares) as of the Determination Date
         less the number of all shares validly tendered and not
         withdrawn as of the Determination Date.

                   (7)  For the purpose of any computation under this
         paragraph and paragraphs (2), (4) and (5) of this Section 4.4,
         the current market price per share of Diamond Offshore Common
         Stock on any date in question shall be deemed to be the average
         of the daily Closing Prices for the 5 consecutive Trading Days
         selected by the Company commencing not more than 20 Trading
         Days before, and ending not later than, the date in question;
         provided, however, that (i) if the "ex" date (as hereinafter
         defined) for any event (other than the issuance or distribution
         requiring such computation) that requires an adjustment to the
         Exchange Rate pursuant to paragraph (1), (2), (3), (4), (5) or
         (6) above ("Other Event") occurs on or after the 20th Trading
         Day prior to the date in question and prior to the "ex" date
         for the issuance or distribution requiring such computation
         (the "Current Event"), the Closing Price for each Trading Day
         prior to the "ex" date for such Other Event shall be adjusted
         by dividing such Closing Price by the same fraction by which
         the Exchange Rate is so required to be adjusted as a result of
         such Other Event, (ii) if the "ex" date for any Other Event
         occurs after the "ex" date for the Current Event and on or
         prior to the date in question, the Closing Price for each
         Trading Day on and after the "ex" date for such Other Event
         shall be adjusted by dividing such Closing Price by the
         reciprocal of the fraction by which the Exchange Rate is so
         required to be adjusted as a result of such Other Event, (iii)
         if the "ex" date for any Other Event occurs on the "ex" date
         for the Current Event, one of those events shall be deemed for
         purposes of clauses (i) and (ii) of this proviso to have an
         "ex" date occurring prior to the "ex" date for the other event,
         and (iv) if the "ex" date for the


                                       -19-




         Current Event is on or prior to the date in question, after
         taking into account any adjustment required pursuant to clause
         (ii) of this proviso, the Closing Price for each Trading Day on
         or after such "ex" date shall be adjusted by adding thereto the
         amount of any cash and the fair market value on the date in
         question (as determined in good faith by the Board of Directors
         in a manner consistent with any determination of such value for
         purposes of paragraph (4) or (5) of this Section 4.4, whose
         determination shall be conclusive and described in a Board
         Resolution) of the portion of the rights, warrants, options,
         evidences of indebtedness, shares of capital stock, securities,
         cash or property being distributed applicable to one share of
         Diamond Offshore Common Stock.  For the purpose of any
         computation under paragraph (6) of this Section 4.4, the
         current market price per share of Diamond Offshore Common Stock
         on any date in question shall be deemed to be the average of
         the daily Closing Prices for the 5 consecutive Trading Days
         selected by the Company commencing on or after the latest (the
         "Commencement Date") of (i) the date 20 Trading Days before the
         date in question, (ii) the date of commencement of the tender
         or exchange offer requiring such computation and (iii) the date
         of the last amendment, if any, of such tender or exchange offer
         involving a change in the maximum number of shares for which
         tenders are sought or a change in the consideration offered,
         and ending not later than the date of the Expiration Time of
         such tender or exchange offer (or, if such Expiration Time
         occurs before the close of trading on a Trading Day, not later
         than the Trading Day immediately preceding the date of such
         Expiration Time); provided, however, that if the "ex" date for
         any Other Event (other than the tender or exchange offer
         requiring such computation) occurs on or after the Commencement
         Date and on or prior to the date of the Expiration Time for the
         tender or exchange offer requiring such computation, the
         Closing Price for each Trading Day prior to the "ex" date for
         such Other Event shall be adjusted by dividing such Closing
         Price by the same fraction by which the Exchange Rate is so
         required to be adjusted as a result of such other event.  For
         purposes of this paragraph, the term "ex" date, (i) when used
         with respect to any issuance or distribution, means the first
         date on which the Diamond Offshore Common Stock trades regular
         way on the relevant exchange or in the relevant market from
         which the Closing Price was obtained without the right to
         receive such issuance or distribution, (ii) when used with
         respect to any subdivision or combination of shares of Diamond
         Offshore Common Stock, means the first date on which the
         Diamond Offshore Common Stock trades regular way on such
         exchange or in such market after the time at which such
         subdivision or combination becomes effective, and (iii) when
         used with respect to any tender or exchange offer means the
         first date on which the Diamond Offshore Common Stock trades
         regular way on such exchange or in such market after the
         Expiration Time of such tender or exchange offer.

                   (8)  The reclassification of Diamond Offshore Common
         Stock into securities other than Diamond Offshore Common Stock
         (other than any reclassification upon a consolidation or merger
         to which Section 4.11 of the Supplemental Indenture applies)
         shall be deemed to involve (a) a distribution of such
         securities other than Diamond Offshore Common Stock to all
         holders of Diamond Offshore Common Stock (and the effective
         date of such reclassification shall be deemed to be the
         Determination Date), and (b) a subdivision or


                                       -20-




         combination, as the case may be, of the number of shares of
         Diamond Offshore Common Stock outstanding immediately prior to
         such reclassification into the number of shares of Diamond
         Offshore Common Stock outstanding immediately thereafter (and
         the effective date of such reclassification shall be deemed to
         be "the day upon which such subdivision becomes effective" or
         "the day upon which such combination becomes effective", as the
         case may be, and "the day upon which such subdivision or
         combination becomes effective" within the meaning of paragraph
         (3) of this Section 4.4).  Rights or warrants issued by Diamond
         Offshore to all holders of Diamond Offshore Common Stock
         entitling the holders thereof to subscribe for or purchase
         shares of Diamond Offshore Common Stock, which rights or
         warrants (i) are deemed to be transferred with such shares of
         Diamond Offshore Common Stock, (ii) are not exercisable and
         (iii) are also issued in respect of future issuances of Diamond
         Offshore Common Stock, in each case in clauses (i) through
         (iii) until the occurrence of a specified event or events
         ("Trigger Event"), shall for purposes of this Section 4.4 not
         be deemed issued until the occurrence of the earliest Trigger
         Event.

                   (9)  Diamond Offshore may make such increases in the
         Exchange Rate, in addition to those required by paragraphs (1),
         (2), (3), (4), (5) and (6) of this Section, as it considers to
         be advisable in order that any event treated for Federal income
         tax purposes as a dividend of stock or stock rights shall not
         be taxable to the recipients.

                   (10)  No adjustment in the Exchange Rate shall be
         required unless such adjustment would require an increase or
         decrease of at least 1% in the Exchange Rate; provided,
         however, that any adjustments which by reason of this paragraph
         (10) are not required to be made shall be carried forward and
         taken into account in any subsequent adjustment.
                   
                   4.5 Notice of Adjustments of Exchange Rate.

                   Whenever the Exchange Rate is adjusted as provided in
         Section 4.4 of this Third Supplemental Indenture:

                   (1)  the Company shall compute the adjusted Exchange
              Rate in accordance with Section 4.4 and shall prepare a
              certificate signed by either the chief financial officer,
              the treasurer or the controller of the Company setting
              forth the adjusted Exchange Rate and showing in reasonable
              detail the facts upon which such adjustment is based, and
              such certificate shall promptly be filed with the Trustee
              and at each office or agency maintained for the purpose of
              exchange of Notes pursuant to Section 4.7 of this Third
              Supplemental Indenture; and

                   (2)  a notice stating that the Exchange Rate has been
              adjusted and setting forth the adjusted Exchange Rate
              shall forthwith be prepared, and as soon as practicable
              after it is prepared, such notice shall be provided by the
              Company to the Trustee and to all Holders.  Unless and
              until the Trustee receives such notice, it need not
              inquire into whether any


                                       -21-




              adjustment of the Exchange Rate is required and may assume
              that no such adjustment has been, or is required to be,
              made.

                   4.6. Notice of Certain Corporate Action.

                   In case:

                   (a)  Diamond Offshore shall declare a dividend (or
              any other distribution) on Diamond Offshore Common Stock
              payable (i) otherwise than exclusively in cash or (ii)
              exclusively in cash in an amount that would require any
              adjustment pursuant to Section 4.4 of this Third
              Supplemental Indenture; or

                   (b)  Diamond Offshore shall authorize the granting to
              the holders of Diamond Offshore Common Stock of rights,
              options or warrants to subscribe for or purchase any
              shares of capital stock of any class or of any other
              rights; or

                   (c)  of any reclassification of Diamond Offshore
              Common Stock, or of any consolidation, merger or share
              exchange to which Diamond Offshore is a party and for
              which approval of any shareholders of Diamond Offshore is
              required, or of the conveyance, sale, transfer or lease of
              all or substantially all of the assets of Diamond
              Offshore; or

                   (d)  of the voluntary or involuntary dissolution,
              liquidation or winding up of Diamond Offshore; or

                   (e)  Diamond Offshore or any subsidiary of Diamond
              Offshore shall commence a tender offer for all or a
              portion of the outstanding shares of Diamond Offshore
              Common Stock (or shall amend any such tender offer);

         then the Company shall cause to be filed with the Trustee and
         at each office or agency maintained for the purpose of
         conversion of Notes pursuant to Section 4.7 of this Third
         Supplemental Indenture, and shall cause to be provided to all
         Holders, by the later of (i) as soon as reasonably practicable
         after the Company has become aware of such matter or (ii) at
         least 20 days (or 10 days in any case specified in clause (a)
         or (b) above) prior to the applicable record, expiration or
         effective date hereinafter specified, a notice stating (x) the
         date on which a record is to be taken for the purpose of such
         dividend, distribution, rights, options or warrants, or, if a
         record is not to be taken, the date as of which the holders of
         Diamond Offshore Common Stock of record to be entitled to such
         dividend, distribution, rights, options or warrants are to be
         determined, (y) the date on which the right to make tenders
         under such tender offer expires or (z) the date on which such
         reclassification, consolidation, merger, conveyance, transfer,
         sale, lease, dissolution, liquidation or winding up is expected
         to become effective, and the date as of which it


                                       -22-




         is expected that holders of Diamond Offshore Common Stock of
         record shall be entitled to exchange their shares of Diamond
         Offshore Common Stock for securities, cash or other property
         deliverable upon such reclassification, consolidation, merger,
         conveyance, transfer, sale, lease, dissolution, liquidation or
         winding up.  Neither the failure to give such notice or the
         notice referred to in the following paragraph nor any defect
         therein shall affect the legality or validity of the
         proceedings described in clauses (a) through (e) of this
         Section 4.6.

                   The preceding paragraph to the contrary
         notwithstanding, the Company shall cause to be filed at each
         office or agency maintained for the purpose of exchange of
         Notes pursuant to Section 4.7 of this Third Supplemental
         Indenture, and shall cause to be provided to all Holders,
         notice of any tender offer by Diamond Offshore or any
         subsidiary of Diamond Offshore for all or any portion of the
         Diamond Offshore Common Stock at or about the time that such
         notice of tender offer is provided to the public generally.

                   4.7.  Maintenance of Office or Agency.

                   The Company will maintain in the Borough of
         Manhattan, The City of New York an office or agency where Notes
         may be surrendered for exchange and where notices and demands
         to or upon the Company in respect of the Notes and the
         Indenture may be served.  The Company will give prompt written
         notice to the Trustee of the location, and any change in the
         location, of such office or agency.  If at any time the Company
         shall fail to maintain any such required office or agency or
         shall fail to furnish the Trustee with the address thereof,
         such surrenders may be made or served at the Corporate Trust
         Office of the Trustee, and the Company hereby appoints the
         Trustee as its agent to receive all such surrenders.

                   The Company may also from time to time designate one
         or more other offices or agencies (in or outside the Borough of
         Manhattan, The City of New York) where the Notes may be
         presented or surrendered for such purpose and may from time to
         time rescind such designations; provided, however, that no such
         designation or rescission shall in any manner relieve the
         Company of its obligation to maintain an office or agency in
         the Borough of Manhattan, The City of New York for such
         purpose.  The Company will give prompt written notice to the
         Trustee of any such designation or rescission and of any change
         in the location of any such other office or agency.

                   4.8  Taxes on Exchanges.

                   Except as provided in the next sentence, the Company
         will pay any and all taxes and duties that may be payable in
         respect of the delivery of shares of Diamond Offshore Common
         Stock pursuant hereto.  The Company shall not, however, be
         required to pay any tax or duty which may be payable in respect
         of any transfer involved in the delivery of shares of Diamond
         Offshore Common Stock in a name other than that of the Holder
         of the Note or Notes


                                       -23-




         to be exchanged, and no such issue or delivery shall be made
         unless and until the Person requesting such issue has paid to
         the Company the amount of any such tax or duty, or has
         established to the satisfaction of the Company that such tax or
         duty has been paid.

                   4.9.  Covenant as to Diamond Offshore Common Stock.

                   The Company agrees that all shares of Diamond
         Offshore Common Stock which may be delivered upon exchange of
         Notes, upon such delivery, will have been duly authorized and
         validly issued and will be fully paid and nonassessable and,
         except as provided in Section 4.8 of this Third Supplemental
         Indenture, the Company will pay all taxes, liens and charges
         with respect to the issue thereof.

                   4.10.  Cancellation of Exchanged Notes.

                   All Notes delivered for exchange shall be delivered
         to the Trustee to be canceled by or at the direction of the
         Trustee, which shall dispose of the same as provided in Section
         309 of the Indenture.

                   4.11.  Provision in Case of Consolidation, Merger or
         Sale of Assets of Diamond Offshore.

                   In case of any consolidation of Diamond Offshore with
         any other Person, any merger of Diamond Offshore into another
         Person or of another Person into Diamond Offshore (other than a
         merger which does not result in any reclassification, exchange,
         exchange or cancellation of outstanding shares of Diamond
         Offshore Common Stock) or any conveyance, sale, transfer or
         lease of all or substantially all of the properties and assets
         of Diamond Offshore, the Company shall execute and deliver to
         the Trustee a supplemental indenture providing that the Holder
         of each Note then Outstanding shall have the right thereafter,
         during the period such Note shall be exchangeable, to exchange
         such Note only into the kind and amount of Notes, cash and
         other property receivable upon such consolidation, merger,
         conveyance, sale, transfer or lease (including any Diamond
         Offshore Common Stock retainable) by a holder of the number of
         shares of Diamond Offshore Common Stock of the Company into
         which such Note might have been exchanged immediately prior to
         such consolidation, merger, conveyance, sale, transfer or
         lease, (a) assuming such holder of Diamond Offshore Common
         Stock (i) is not a Person with which Diamond Offshore
         consolidated, into which Diamond Offshore merged or which
         merged into Diamond Offshore or to which such conveyance, sale,
         transfer or lease was made, as the case may be (a "Constituent
         Person"), or an Affiliate of a Constituent Person and (ii)
         failed to exercise his rights of election, if any, as to the
         kind or amount of securities, cash and other property
         receivable upon such consolidation, merger, conveyance, sale,
         transfer or lease (provided that if the kind or amount of
         securities, cash and other property receivable upon such
         consolidation, merger, conveyance, sale, transfer, or lease is
         not the same for each share of Diamond Offshore


                                       -24-




         Common Stock held immediately prior to such consolidation,
         merger, conveyance, sale, transfer or lease by others than a
         Constituent Person or an Affiliate thereof and in respect of
         which such rights of election shall not have been exercised
         ("Non-electing Share"), then for the purpose of this Section
         4.11 the kind and amount of securities, cash and other property
         receivable upon such consolidation, merger, conveyance, sale,
         transfer or lease by the holders of each Non-electing Share
         shall be deemed to be the kind and amount so receivable per
         share by a plurality of the Non-electing Shares), and (b)
         further assuming that, if such consolidation, merger,
         conveyance, transfer, sale or lease occurs before the first
         date on which Notes may be exchanged as provided herein, such
         Note was exchangeable immediately prior to the time of such
         occurrence at the initial Exchange Rate as adjusted from the
         original issue date of the Notes to such time as provided
         herein.  Such supplemental indenture shall provide for
         adjustments which, for events subsequent to the effective date
         of such supplemental indenture, shall be as nearly equivalent
         as may be practicable to the adjustments provided for in this
         Section 4.  The above provisions of this Section 4.11 shall
         similarly apply to successive consolidations, mergers,
         conveyances, sales, transfers or leases.  Notice of the
         execution of such a supplemental indenture shall be given by
         the Company to the Holder of each Note promptly upon such
         execution.  In this paragraph, "securities of the kind
         receivable" upon such consolidation, merger, conveyance,
         transfer, sale or lease by a holder of Diamond Offshore Common
         Stock means securities that, among other things, are registered
         and transferable under the Securities Act, and listed and
         approved for quotation in all securities markets, in each case
         to the same extent as such securities so receivable by a holder
         of Diamond Offshore Common Stock.

                   Neither the Trustee nor any Paying Agent shall be
         under any responsibility to determine the correctness of any
         provisions contained in any such supplemental indenture
         relating either to the kind or amount of shares of stock or
         other securities or property or cash receivable by Holders upon
         the exchange of their Notes after any such consolidation,
         merger, conveyance, transfer, sale or lease or to any such
         adjustment, but may accept as conclusive evidence of the
         correctness of any such provisions, and shall be protected in
         relying upon, an Opinion of Counsel with respect thereto, which
         the Company shall cause to be furnished to the Trustee upon
         request.
                   4.12. Responsibility of Trustee for Exchange
         Provisions.

                   The Trustee, subject to the provisions of Section 601
         of the Indenture, shall not at any time be under any duty or
         responsibility to any Holder to determine whether any facts
         exist which may require any adjustment of the Exchange Rate, or
         with respect to the nature or extent of any such adjustment
         when made, or with respect to the method employed, or herein or
         in any supplemental indenture provided to be employed, in
         making the same, or whether a supplemental indenture need be
         entered into.  The Trustee, in such capacity and subject to the
         provisions of Section 601 of the Indenture, shall not be
         accountable with respect to the validity or value (or the kind
         or amount) of any Diamond Offshore Common Stock, or of any
         other securities or property or cash, which may at any time be
         issued or delivered upon the exchange of any Note; and it or


                                       -25-




         they do not make any representation with respect thereto.  The
         Trustee, in such capacity and subject to the provisions of
         Section 601 of the Indenture, shall not be responsible for any
         failure of the Company to make or calculate any cash payment or
         to issue, transfer or deliver any shares of Diamond Offshore
         Common Stock or share certificates or other securities or
         property or cash upon the surrender of any Note for the purpose
         of conversion; and the Trustee, subject to the provisions of
         Section 601 of the Indenture, shall not be responsible for any
         failure of the Company to comply with any of the covenants of
         the Company contained in this Section.

                   4.13.  Registration.

                   The Company will use its best efforts to effect or
         cause to be effected all registrations with, and obtain all
         approvals by, all governmental authorities that may be
         necessary under any United States Federal or state law
         (including the Securities Act, the Exchange Act and state
         securities and Blue Sky laws) for the shares of Diamond
         Offshore Common Stock issuable upon conversion of Notes to be
         lawfully issued and delivered as provided herein, and
         thereafter freely transferrable.

                   5.  Miscellaneous.

                   (a)  The Trustee accepts the trusts created by the
         Indenture, as supplemented by this Third Supplemental
         Indenture, and agrees to perform the same upon the terms and
         conditions of the Indenture, as supplemented by this Third
         Supplemental Indenture.

                   (b)  The recitals contained herein shall be taken as
         statements of the Company, and the Trustee assumes no
         responsibility for their correctness.  The Trustee makes no
         representations as to the validity or sufficiency of this Third
         Supplemental Indenture.

                   (c)  All covenants and agreements in this Third
         Supplemental Indenture by the Company or the Trustee shall bind
         its respective successors and assigns, whether so expressed or
         not.

                   (d)  In case any provisions in this Third
         Supplemental Indenture shall be invalid, illegal or
         unenforceable, the validity, legality and enforceability of the
         remaining provisions shall not in any way be affected or
         impaired thereby.

                   (e)  Nothing in this Third Supplemental Indenture,
         express or implied, shall give to any Person, other than the
         parties hereto and their successors under the Indenture and the
         Holders of the Notes, any benefit or any legal or equitable
         right, remedy or claim under the Indenture.

                   (f)  If any provision hereof limits, qualifies or
         conflicts with a provision of the


                                       -26-




         Trust Indenture Act of 1939, as may be amended from time to
         time, that is required under such Act to be a part of and
         govern this Third Supplemental Indenture, the latter provision
         shall control.  If any provision hereof modifies or excludes
         any provision of such Act that may be so modified or excluded,
         the latter provision shall be deemed to apply to this Third
         Supplemental Indenture as so modified or excluded, as the case
         may be.

                   (g)  This Third Supplemental Indenture shall be
         governed by and construed in accordance with the laws of the

                   This instrument may be executed in any number of
         counterparts, each of which so executed shall be deemed to be
         an original, but all such counterparts shall together
         constitute but one and the same instrument.

         Diamond Offshore Drilling, Inc.
         15415 Katy Freeway
         Houston, TX 77094

         Attention:     Richard L. Lionberger
                        Vice President, General Counsel and Secretary

         Gentlemen:

                   Reference is made to the Registration Rights
         Agreement dated October 16, 1995 (the "Agreement") between you
         (the "Company") and the undersigned ("Loews").  Capitalized
         terms used and not otherwise defined herein are used with
         meanings given thereto in the Agreement.

                   1.   Demand Registration.  This letter constitutes
         Loews's written request (being the first of three such requests
         to which Loews is entitled) pursuant to Section 2.1 of the
         Agreement that the Company prepare and file, and use its best
         efforts to cause to become effective as soon as practicable
         (but not later than September 30, 1998), one or more
         registration statements under the Act for a continuous offering
         by Loews of shares of Registerable Common Stock under Rule 415
         promulgated by the Commission under the Act (the "Registration
         Statement").  The shares of Registerable Common Stock covered
         by this request will underlie a proposed issuance by Loews of
         its Exchangeable Notes due 2007 ("Exchangeable Notes") through
         a public offering of such notes to be underwritten by Goldman,
         Sachs & Co. (the "Note Offering").  Loews expects to price the
         Note Offering on or about September 16, 1997 at which time
         Loews will advise the Company of the exact number of shares of
         Registerable Common Stock to be covered by this request and the
         Registration Statement.





                   2.   The Registration Statement.

                             (i)  Notwithstanding Section 5(h) of the
         Agreement, the Company agrees to keep effective the
         Registration Statement until the first to occur of (A)
         September 15, 2007 and (B) such time as no Exchangeable Notes
         remain outstanding.

                            (ii)  Loews agrees that the Company may, by
         giving one business day's written notice to Loews, and the
         trustee and the exchange agent for the Exchangeable Notes
         (which notice shall specify that it is given on behalf of Loews
         under the indenture for the Exchangeable Notes (the
         "Indenture")), defer filing the Registration Statement to a
         date later than September 30, 1998, or, at any time and from
         time to time after the Registration Statement has been filed
         and declared effective, require Loews to suspend use of any
         resale prospectus or prospectus supplement included in the
         Registration Statement (A) for a reasonable period of time, but
         not in excess of ninety (90) days, if the Company (x) is at
         such time conducting or about to conduct an underwritten public
         offering of its securities for its own account and the Board of
         Directors of the Company determines in good faith that such
         offering would be materially adversely affected by such use, or
         (y) would, in the opinion of the Company's counsel, be required
         to disclose in such Registration Statement information not
         otherwise then required by law to be publicly disclosed and, in
         the good faith judgment of the Board of Directors of the
         Company, such disclosure would reasonably be expected to
         adversely affect any material business transaction or
         negotiation in which the Company is then engaged or (B) for any
         period during which the Company has notified Loews and the
         exchange agent for the Exchangeable Notes of the occurrence of
         an event requiring the preparation of a supplement to the
         resale prospectus included in the Registration Statement or an
         amendment to the Registration Statement so that, as thereafter
         delivered to holders of the Exchangeable Notes exchanging such
         notes for shares of Registerable Common Stock, such prospectus
         will not contain an 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, in light of the
         circumstances under which they were made, not misleading, and
         as promptly as practicable make available to Loews any such
         supplement or amendment.  Notwithstanding the foregoing, such
         suspensions of use of any such resale prospectus or prospectus
         supplement shall not be in effect for more than 120 days in any
         twelve-month period.

                           (iii)  Loews further agrees that the
         provisions of paragraph (ii) above shall apply to any future
         request for registration made by Loews under Section





                                       -2-





         2.1 of the Agreement if such request relates to a "shelf"
         registration requested to be filed by the Company pursuant to
         Rule 415 promulgated under the Act.

                   3.   Underwriting Agreement.  Pursuant to Section
         5(1) of the Agreement, the Company agrees to enter into the
         underwriting agreement, in the form attached hereto as Exhibit
         "A".

                   4.   Limitations on Suspension Periods.
         Notwithstanding the provisions of Section 2(ii) hereof, the
         Company agrees with Loews that it will not suspend the use of
         any resale prospectus or prospectus supplement included in the
         Registration Statement (i) during the 14-day period preceding
         the final maturity date of the Exchangeable Notes or, subject
         to compliance by Loews with the provisions of this Section 4,
         during the 14-day period preceding any Redemption Date (as
         defined in Loews's prospectus supplement for the Exchangeable
         Notes (the "Prospectus Supplement")) with respect to the
         Exchangeable Notes.  Loews agrees not to give notice under the
         Indenture to the holders of Exchangeable Notes of any proposed
         optional redemption at any time when use of any such prospectus
         or prospectus supplement has been suspended by the Company in
         accordance with this letter.  Prior to giving notice under the
         Indenture to the holders of Exchangeable Notes of any proposed
         optional redemption, Loews agrees to provide the Company with
         at least three full Trading Days' (as defined in the Prospectus
         Supplement) written notice (or such shorter period as the
         Company may agree) of such proposed optional redemption (the
         "Redemption Notice").  On or before the close of business on
         the third Trading Day following actual receipt by the Company
         of the Redemption Notice, the Company will notify Loews if the
         Company elects to suspend the use of any resale prospectus or
         prospectus supplement pursuant to Section 2(ii) above.  If the
         Company elects to suspend use of any resale prospectus or
         prospectus supplement, the Company will effect such suspension
         promptly and Loews will not give notice of any proposed
         optional redemption until the suspension period has terminated
         or expired.

                   5.   Effect Hereof.  This letter agreement
         constitutes an amendment to the Agreement pursuant to Section
         12.5 thereof and the general provisions of such agreement apply
         to this letter agreement (except the notice provisions hereof
         will control over Section 12.7 thereof in the event of any
         inconsistency).  As amended hereby, the Agreement is hereby
         confirmed to be and remain in full force and effect.

                   If this letter correctly sets forth our mutual
         understanding regarding the amendment to the Agreement proposed
         to be effected hereby, please so indicate by





                                       -3-





         executing each copy hereof, whereupon this letter shall
         constitute an agreement between us to amend the Agreement, and
         otherwise as set forth above.
