clause (a)(i), (ii) and (iii) and clause (b) have not previously been delivered
in connection with any Prior Transfers, the documents relating to such Prior
Transfers shall be delivered by the transferring entity to the transferee. Each
of the parties hereto also agrees to deliver to any other party hereto such
other documents, instruments and writings as may be reasonably requested by such
other parties hereto in connection with the transactions contemplated hereby or
by Prior Transfers. Notwithstanding any other provisions of this Agreement to
the contrary, (x) THE TRANSFERS AND ASSUMPTIONS REFERRED TO IN THIS ARTICLE II
(INCLUDING PRIOR TRANSFERS) HAVE BEEN, OR WILL BE, MADE WITHOUT ANY
REPRESENTATION OR WARRANTY OF ANY NATURE (A) AS TO THE VALUE OR FREEDOM FROM
ENCUMBRANCE OF, ANY ASSETS, (B) AS TO ANY WARRANTY OF MERCHANTABILITY OR
WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE OF, OR ANY OTHER MATTER CONCERNING,
ANY ASSETS OR (C) AS TO THE LEGAL SUFFICIENCY TO CONVEY TITLE TO ANY ASSETS, and
(y) the instruments of transfer or assumption referred to in this Section 2.4
shall not include any

                                       17
<PAGE>
representations and warranties other than as specifically provided herein.
Transocean and TODCO hereby acknowledge and agree that ALL ASSETS TRANSFERRED
PURSUANT TO THIS ARTICLE II AND ALL ASSETS INCLUDED IN PRIOR TRANSFERS ARE BEING
OR WERE TRANSFERRED "AS IS, WHERE IS." To the extent that the instruments of
transfer and assumption with respect to any Prior Transfers are inconsistent
with this Section 2.4, the TODCO Group and the Transocean Group agree that the
inconsistent provisions of such instruments are hereby amended and superseded by
the provisions of this Section 2.4. To the extent reasonably requested by a
member of either Group, each party will, or will cause its Subsidiaries to,
execute any documents necessary to evidence such amendment.

         2.5 NO REPRESENTATIONS OR WARRANTIES. Except as expressly set forth in
this Agreement or in an Ancillary Agreement, TODCO, Transocean Holdings and
Transocean understand and agree that no member of the Transocean Group is
representing or warranting to TODCO or any member of the TODCO Group in any way
as to the TODCO Business or the TODCO Liabilities. Except as expressly set forth
in this Agreement or in an Ancillary Agreement, Transocean, Transocean Holdings
and TODCO understand and agree that no member of the TODCO Group is representing
or warranting to Transocean or any member of the Transocean Group in any way as
to the Transocean Business or the TODCO Excluded Liabilities.

         2.6 AGREEMENTS. Prior to the Exchange, Transocean and TODCO shall
execute and deliver (or shall cause their appropriate Subsidiaries to execute
and deliver, as applicable) the agreements between them designated as follows:

                           (i) the Transition Services Agreement,

                           (ii) the Employee Matters Agreement,

                           (iii) the Tax Sharing Agreement,

                           (iv) the Registration Rights Agreement, and

                           (v) such other written agreements, documents or
                  instruments as the parties may agree are necessary or
                  desirable and which specifically state that they are Ancillary
                  Agreements within the meaning of this Agreement

(collectively, the "Ancillary Agreements"). To the extent such documents are not
executed and delivered before the Exchange, they shall be executed and delivered
as soon as practicable thereafter and (except as otherwise provided therein)
shall be effective immediately before the Exchange.

         2.7 TRANSFERS NOT EFFECTED PRIOR TO THE EXCHANGE DATE.

                  (a) To the extent that any transfers contemplated by this
Article II shall not have been consummated as of the Exchange, the parties shall
cooperate to effect such transfers as promptly following the Exchange as shall
be practicable. Nothing herein shall be deemed to require the transfer of any
assets or the assumption of any Liabilities that by their terms or

                                       18
<PAGE>

operation of law cannot be transferred or assumed; provided that the TODCO Group
and the Transocean Group shall cooperate to obtain any necessary consents or
approvals for the transfer of all assets and the assumption of all Liabilities
contemplated to be transferred or assumed pursuant to this Article II and shall,
even in the absence of necessary consents or approvals, transfer the equitable
ownership of assets when such a transfer is permitted. In the event that any
such transfer of assets or assumption of Liabilities has not been consummated
effective as of the time of the Exchange, the party retaining such asset or
Liability shall thereafter hold such asset in trust for the use and benefit of
the party entitled thereto (at the expense of the party entitled thereto) and
retain such Liability for the account of the party by whom such liability is to
be assumed pursuant hereto, and take such other action as may be reasonably
requested by the party to which such asset is to be transferred, or by whom such
liability is to be assumed, as the case may be, in order to place such party,
insofar as reasonably possible, in the same position as would have existed had
such asset or Liability been transferred or assumed as contemplated hereby.
Without limiting any other duty of a party holding any asset in trust for the
use and benefit of the party entitled thereto, such party shall take all
reasonable actions necessary to preserve the value of that asset. As and when
any such asset becomes transferable or such Liability can be assumed, such
transfer or assumption shall be effected forthwith. Subject to the foregoing,
the parties agree that, as of the time of the Exchange (or such earlier time as
any such asset may have been acquired or Liability assumed pursuant to a Prior
Transfer), each party hereto shall be deemed to have acquired complete and sole
beneficial ownership over all of the assets, together with all rights, powers
and privileges incident thereto, and shall be deemed to have assumed in
accordance with the terms of this Agreement all of the Liabilities, and all
duties, obligations and responsibilities incident thereto, which such party is
entitled to acquire or required to assume pursuant to the terms of this
Agreement.

                  (b) If two years after the IPO Closing Date any asset remains
subject to an arrangement described in Section 2.7(a), the beneficial owner may
(i) direct the party acting as trustee to transfer the asset to the beneficial
owner, at the sole risk of such beneficial owner (who will thereafter indemnify
the trustee/transferor from all Losses and Liabilities, other than Taxes (which
are covered by the Tax Sharing Agreement), arising as a result of such
transfer), (ii) direct the party acting as trustee to sell or liquidate the
subject asset for the account of, and at the sole risk and expense of, such
beneficial owner, who shall be entitled to receive all of the net proceeds of
such sale or liquidation or (iii) continue the arrangement described in Section
2.7(a).

         2.8 ADDITIONAL TRANSFERS OF ASSETS.

                  (a) Without limiting the generality of Section 2.1, for a
period beginning on the date of the Exchange and ending on the date one year
following the IPO Closing Date, if Transocean in its good faith judgment, after
reasonable consultation with the General Counsel of TODCO, or other person
designated by TODCO, identifies any asset owned by a member of the Transocean
Group or a member of the TODCO Group, as applicable, that (i) during the twelve
(12) month period prior to the date of the Exchange was used primarily in the
TODCO Business and is then owned by a member of the Transocean Group or (ii)
during the twelve (12) month period prior to the date of the Exchange was used
primarily in the Transocean Business and is then owned by a member of the TODCO
Group, Transocean or TODCO, as the case may be, shall or shall cause any such
asset to be conveyed, assigned, transferred and delivered in

                                       19
<PAGE>

accordance with Section 2.4 to the entity identified by TODCO or Transocean, as
the case may be, as the appropriate transferee.

                  (b) The parties hereto acknowledge and agree that any
transfers pursuant to this Section 2.8 are to be made without any additional
consideration.

                  (c) All conveyances, assignments, transfers and deliveries of
assets occurring after the Exchange pursuant to this Section 2.8 shall be
governed by the terms of this Agreement. In furtherance of the foregoing, any
asset transferred pursuant to this Section 2.8 to a member of the TODCO Group
shall be deemed an asset of the TODCO Business, and any asset transferred to a
member of the Transocean Group shall be deemed an asset of the Transocean
Business.

         2.9 WORKING CAPITAL. The parties to this Agreement acknowledge that the
amount of cash and cash equivalents of TODCO and its Subsidiaries as of June 30,
2003 was $25.0 million, after giving effect to a payment by Transocean to TODCO
of approximately $11.4 million after June 30, 2003. The amount paid to TODCO by
Transocean equals the difference between $25.0 million and the amount of cash
and cash equivalents of TODCO and its Subsidiaries as of June 30, 2003 prior to
giving effect to the payment by Transocean. TODCO and its Subsidiaries shall
retain all cash and cash equivalents generated by the TODCO Business following
June 30, 2003. Transocean shall not be required to make any additional payments
to TODCO or its Subsidiaries for their working capital needs except as otherwise
expressly agreed in writing. As used in this Section 2.9, cash and cash
equivalents are determined in accordance with GAAP and the financial reporting
policies and procedures used by TODCO and its Subsidiaries prior to the IPO
Closing Date, as reflected in the consolidated financial statements and pro
forma information of TODCO and its Subsidiaries included in the IPO Prospectus.

all Persons who at any time prior to the IPO Closing Date have been

have existed on or before the IPO Closing Date, including in connection with the
transactions and all other activities to implement Prior Transfers, the
Separation, the IPO and any Distribution.

                  (c) Nothing contained in Section 3.1(a) or (b) shall impair
any right of any Person to enforce this Agreement, any Ancillary Agreement or
any agreements, arrangements, commitments or understandings that are specified
in, or contemplated to continue pursuant to, this Agreement or any Ancillary
Agreement. Nothing contained in Section 3.1(a) or (b) shall release any Person
from:

                           (i) any Liability, contingent or otherwise, assumed,
                  transferred, assigned or allocated to the Group of which such
                  Person is a member in accordance with, or any other Liability
                  of any member of either Group under, this Agreement or any
                  Ancillary Agreement;

                           (ii) any Liability that the parties may have with
                  respect to indemnification or contribution pursuant to this
                  Agreement for claims brought against the parties by third
                  Persons, which Liability shall be governed by the provisions
                  of this Article III and, if applicable, the appropriate
                  provisions of the Ancillary Agreements;

                           (iii) any Liability the release of which would result
                  in the release of any Person other than an Indemnitee;
                  provided that the parties agree not to bring suit or permit
                  any of their Subsidiaries to bring suit against any Indemnitee
                  with respect to such Liability; or

                           (iv) any Liability with respect to the TODCO Debt

                  (d) TODCO shall not make, and shall not permit any member of
the TODCO Group to make, any claim or demand, or commence any Action asserting
any claim or demand, including any claim of contribution or indemnification,

<PAGE>

asserting any claim or demand, including any claim of contribution or any
indemnification, against TODCO or any member of the TODCO Group, or any other
Person released pursuant to Section 3.1(b), with respect to any Liabilities
released pursuant to Section 3.1(b).

                  (e) It is the intent of each of Transocean and TODCO by virtue
of the provisions of this Section 3.1 to provide for a full and complete release
and discharge of all Liabilities existing or arising from all acts and events
occurring or failing to occur or alleged to have occurred or to have failed to
occur and all conditions existing or alleged to have existed on or before the
IPO Closing Date, between or among TODCO or any member of the TODCO Group, on
the one hand, and Transocean or any member of the Transocean Group, on the other
hand (including any contractual agreements or arrangements existing or alleged
to exist between or among any such members on or before the IPO Closing Date),
except as expressly set forth in Section 3.1(c). At any time, at the request of
any other party, each party shall cause each member of its respective Group to
execute and deliver releases reflecting the provisions hereof.

         3.2 TERMINATION OF INTERCOMPANY AGREEMENTS AND ASSUMPTION OF
INTERCOMPANY BALANCES.

                  (a) Without limiting the generality of Section 3.1(e) and
subject to the terms of Section 3.1, each of the parties hereto agrees that,
except for (i) this Agreement, the Ancillary Agreements (including any amounts
owed with respect to such agreements), (ii) any amounts owed by (other than
amounts owed with respect to any agreement in clause (i)) TODCO or one of its
Subsidiaries to Transocean or one of its Subsidiaries immediately prior to the
Exchange (the "Intercompany Payables"), and (iii) any amounts owed (other than
amounts owed with respect to any agreement in clause (i)) by Transocean or one
of its Subsidiaries to TODCO or one of its Subsidiaries immediately prior to the
Exchange (the "Intercompany Receivables"), all Intercompany Agreements and all
other intercompany arrangements and course of dealings whether or not in writing
and whether or not binding or in effect immediately prior to the Exchange shall
terminate immediately prior to the Exchange unless the parties thereto otherwise
agree in writing after the date of this Agreement.

                  (b) Except to the extent previously discharged, the
Intercompany Payables shall be assumed by Transocean Holdings and the
Intercompany Receivables, other than TODCO's outstanding 6.75%, 7.375% and 9.50%
notes, if any, held by Transocean or Transocean Holdings, shall be distributed
by TODCO to Transocean Holdings immediately prior to the Exchange; provided,
however, that (i) the foregoing shall be without prejudice to the terms of
Section 7.14, including without limitation any accrued rights, insurance
proceeds or Intercompany Payables for premiums, (ii) Intercompany Payables for
services similar to those provided under the Transition Services Agreement or
Employee Matters Agreement that were rendered prior to the Exchange shall remain
the obligation of TODCO or its respective Affiliates, and (iii) Intercompany
Payables relating to third-party vendors for services rendered to or on behalf
of the TODCO Business prior to the Exchange shall remain the obligation of
TODCO.

         3.3 INDEMNIFICATION BY TODCO. Except as provided in Sections 3.6 and
3.7, TODCO shall, and in the case of clauses (a), (b) and (c) below shall in
addition cause the Appropriate Member of the TODCO Group to, indemnify, defend
and hold harmless Transocean, each member of the Transocean Group and their
respective Affiliates, successors and assigns, and all stockholders, directors,
officers, agents or employees of any member of the Transocean Group (in each
case, in their respective capacities as such), and their respective heirs,
executors, administrators, successors

                                       22
<PAGE>

and assigns (collectively, the "Transocean Indemnitees") from and against any
and all Losses of the Transocean Indemnitees relating to, arising out of or
resulting from any of the following (without duplication):

                  (a) the failure of TODCO or any other member of the TODCO
Group or any other Person to pay, perform or otherwise promptly discharge any
TODCO Liabilities in accordance with their respective terms, whether prior to or
after the IPO Closing Date or the date thereof;

                  (b) the TODCO Business or any TODCO Liability;

                  (c) any breach by TODCO or any member of the TODCO Group of
this Agreement or any of the Ancillary Agreements; and

                  (d) any untrue statement or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact required
to be stated therein or necessary to make the statements therein not misleading,
with respect to all Information contained in the IPO Registration Statement or
any IPO Prospectus (other than Information regarding Transocean included in the
IPO Registration Statement or any IPO Prospectus set forth on Schedule 3.3(d) or
in the Information required to be supplied pursuant to Section 7.4(d)).

As used in this Section 3.3, "Appropriate Member of the TODCO Group" means the
member or members of the TODCO Group, if any, whose acts, conduct or omissions
or failures to act caused, gave rise to or resulted in the loss from and against
which indemnity is provided.

         3.4 INDEMNIFICATION BY TRANSOCEAN HOLDINGS. Except as provided in
Sections 3.6 and 3.7, Transocean Holdings shall, and in case of clauses (a), (b)
and (c) below shall in addition cause the Appropriate Member of the Transocean
Group to, indemnify, defend and hold harmless TODCO, each member of the TODCO
Group and their respective Affiliates, successors and assigns, and all
shareholders, directors, officers, agents or employees of any member of the
TODCO Group (in each case, in their respective capacities as such), and their
respective heirs, executors, administrators, successors and assigns
(collectively, the "TODCO Indemnitees") from and against any and all Losses of
the TODCO Indemnitees relating to, arising out of or resulting from any of the
following (without duplication):

                  (a) the failure of Transocean or any other member of the
Transocean Group or any other Person to pay, perform or otherwise promptly
discharge any Liabilities of any member of the Transocean Group other than the
TODCO Liabilities, in accordance with their respective terms, whether prior to
or after the IPO Closing Date or the date hereof;

                  (b) the Transocean Business or any Liability of any member of
the Transocean Group other than the TODCO Liabilities;

                  (c) any breach by Transocean or any member of the Transocean
Group of this Agreement or any of the Ancillary Agreements; and

                                       23
<PAGE>

                  (d) any untrue statement or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact required
to be stated therein or necessary to make the statements therein not misleading,
with respect to information regarding Transocean provided by Transocean in
writing to TODCO for inclusion in the IPO Registration Statement or any IPO
Prospectus.

As used in this Section 3.4, "Appropriate Member of the Transocean Group" means
the member or members of the Transocean Group, if any, whose acts, conduct or
omissions or failures to act caused, gave rise to or resulted in the Loss from
and against which indemnity is provided.

         3.5 TRANSOCEAN'S GUARANTEE OF TRANSOCEAN HOLDINGS' INDEMNIFICATION
OBLIGATION. If Transocean Holdings fails to perform any of its obligations under
Section 3.4 above, then Transocean shall indemnify, defend and hold harmless the
TODCO Indemnitees from and against any and all Losses of the TODCO Indemnitees
relating to, arising out of or resulting from any of the matters described in
clauses (a), (b), (c) and (d) of Section 3.4 (without duplication).

         3.6 INDEMNIFICATION OBLIGATIONS NET OF INSURANCE PROCEEDS.

                  (a) The parties intend that any Loss subject to
indemnification or reimbursement pursuant to this Article III (an "Indemnifiable
Loss") will be net of Insurance Proceeds that actually reduce the amount of the
Loss. Accordingly, the amount which any party (an "Indemnifying Party") is
required to pay to any Person entitled to indemnification hereunder (an
"Indemnitee") will be reduced by any Insurance Proceeds theretofore actually
recovered by or on behalf of the Indemnitee in reduction of the related Loss. If
an Indemnitee receives a payment (an "Indemnity Payment") required by this
Agreement from an Indemnifying Party in respect of any Loss and subsequently
receives Insurance Proceeds, then the Indemnitee will pay to the Indemnifying
Party an amount equal to the excess of the Indemnity Payments received over the
amount of the Indemnity Payments that would have been due if the Insurance
Proceeds recovery had been received, realized or recovered before the Indemnity
Payments were made. The existence of a claim by an Indemnitee for insurance or
against a third party in respect of any Indemnifiable Loss shall not, however,
delay any payment pursuant to the indemnification provisions contained in this
Article III and otherwise determined to be due and owing by an Indemnifying
Party. Rather the Indemnifying Party shall make payment in full of such amount
so determined to be due and owing by it against an assignment by the Indemnitee
to the Indemnifying Party of the portion of the claim of the Indemnitee for such
insurance or against such third party equal to the amount of such payment. The
Indemnitee shall use and cause its Affiliates to use commercially reasonable
efforts to assist the Indemnifying Party in recovering or to recover on behalf
of the Indemnifying Party, any Insurance Proceeds to which the Indemnifying
Party is entitled with respect to any Indemnifiable Loss as a result of such
assignment. The Indemnitee shall make available to the Indemnifying Party and
its counsel all employees, books and records, communications, documents, items
or matters within its knowledge, possession or control that are necessary,
appropriate or reasonably deemed relevant by the Indemnifying Party with respect
to the recovery of such Insurance Proceeds; provided, however, that subject to
Section 7.7 hereof, nothing in this sentence shall be deemed to require a party
to make available books and records, communications, documents or items which
(i) in such party's good faith judgment could result in a waiver of any
Privilege or (ii) such party is not

                                       24
<PAGE>

permitted to make available because of any Law or any confidentiality obligation
to a third party, in which case such party shall use its reasonable commercial
efforts to seek a waiver of or other relief from such confidentiality
restriction. Unless the Indemnifying Party has made payment in full of any
Indemnifiable Loss, such Indemnifying Party shall use and cause its Affiliates
to use commercially reasonable efforts to recover any Insurance Proceeds to
which it or such Affiliate is entitled with respect to any Indemnifiable Loss.

                  (b) An insurer who would otherwise be obligated to pay any
claims shall not be relieved of the responsibility with respect thereto or,
solely by virtue of the indemnification provisions hereof, have any subrogation
rights with respect thereto, it being expressly understood and agreed that no
insurer or any other third party shall be entitled to a "windfall" (i.e., a
benefit it would not be entitled to receive in the absence of the
indemnification provisions) by virtue of the indemnification provisions hereof.

         3.7 INDEMNIFICATION OBLIGATIONS NET OF TAXES. The parties intend that
any Loss subject to indemnification or reimbursement pursuant to this Article
III will be net of Taxes. Accordingly, the amount which an Indemnifying Party is
required to pay to an Indemnitee will be adjusted to reflect any tax benefit to
the Indemnitee from the underlying Loss and to reflect any Taxes imposed upon
the Indemnitee as a result of the receipt of such payment. Such an adjustment
will first be made at the time that the indemnity payment is made and will
further be made, as appropriate, to take into account any change in the
liability of the Indemnitee for Taxes that occurs in connection with the final
resolution of an audit by a taxing authority. For purposes of this Section 3.7,
the value of such tax benefit shall be an amount equal to the product of (x) the
amount of the deduction allowed to the Indemnitee by the Code as a result of the
underlying Loss and (y) the highest statutory rate applicable under Section 11
of the Code. Notwithstanding the immediately preceding sentence, if the Loss
subject to indemnification exceeds U.S. $1.0 million (determined on an
item-by-item basis) and such deduction, or portion thereof, creates or increases
a net operating loss under section 172 of the Code, then (i) such deduction, or
portion thereof, will not be included in the computation of the tax benefit and
(ii) the Indemnitee shall pay the Indemnifying party the amount by which the tax
benefit is reduced by application of this sentence when such net operating loss
is used or absorbed by the Indemnitee. To the extent permitted by law, the
parties will treat any indemnity payment as a capital contribution made by
Transocean Holdings to TODCO or as a distribution made by TODCO to Transocean
Holdings, as the case may be, immediately prior to the date recited above on
which the parties entered into this Agreement.

         3.8 PROCEDURES FOR INDEMNIFICATION OF THIRD PARTY CLAIMS.

                  (a) If an Indemnitee shall receive notice or otherwise learn
of the assertion by a Person (including any Governmental Authority) who is not a
member of the Transocean Group or the TODCO Group of any claims or of the
commencement by any such Person of any Action (collectively, a "Third Party
Claim") with respect to which an Indemnifying Party may be obligated to provide
indemnification to such Indemnitee pursuant to Section 3.3 or 3.4, or any other
Section of this Agreement or any Ancillary Agreement, such Indemnitee shall
promptly give such Indemnifying Party written notice thereof. Any such notice
shall describe the Third Party Claim in reasonable detail. Notwithstanding the
foregoing, the failure of any Indemnitee or other Person to give notice as
provided in this Section 3.8(a) shall not relieve the related

                                       25
<PAGE>

Indemnifying Party of its obligations under this Article III, except to the
extent that such Indemnifying Party is actually prejudiced by such failure to
give notice.

                  (b) An Indemnifying Party may elect to defend (and, unless the
Indemnifying Party has specified any reservations or exceptions, to seek to
settle or compromise), at such Indemnifying Party's own expense and by such
Indemnifying Party's own counsel, any Third Party Claim. Within 30 days after
the receipt of notice from an Indemnitee in accordance with Section 3.8(a) (or
sooner, if the nature of such Third Party Claim so requires), the Indemnifying
Party shall notify the Indemnitee of its election whether the Indemnifying Party
will assume responsibility for defending such Third Party Claim, which election
shall specify any reservations or exceptions. The failure to give such notice of
election within the 30-day period shall be deemed a rejection of the opportunity
to assume responsibility. After notice from an Indemnifying Party to an
Indemnitee of its election to assume the defense of a Third Party Claim (or in
the case where Transocean, as the Indemnitee or on behalf of a member of the
Transocean Group as the Indemnitee, elects to defend a Third Party Claim
pursuant to paragraph (b)(i) or (b)(ii), after notice from Transocean to the
Indemnifying Party), such non-defending party shall have the right to employ
separate counsel and to participate in (but not control) the defense, compromise
or settlement thereof, but the fees and expenses of such counsel shall be at the
expense of such non-defending party. Notwithstanding the foregoing, Transocean,
in its sole discretion, upon written notice (which notice shall include
Transocean's basis for electing to defend such Third Party Claim and whether or
not Transocean has specified, and continues to assert, any reservations or
exceptions with respect to such Third Party Claim), may elect to defend or
assume the defense of (and to seek to settle or compromise) any Third Party
Claim or series of related Third Party Claims:

                           (i) that relate in any way to the TODCO Business or
                  the TODCO Liabilities if a member of the Transocean Group is
                  named a party thereto and if (x) Transocean or one of its
                  Subsidiaries' ability to conduct its business could be
                  impaired in any significantly adverse manner as a result of
                  any injunctive relief sought or (y) an adverse resolution of
                  such Third Party Claim (or series of related Third Party
                  Claims) presents in the good faith judgment of Transocean's
                  General Counsel a reasonable risk of having a material adverse
                  effect on the business, operations, financial condition,
                  results of operations or prospects of Transocean and its
                  Subsidiaries, taken as a whole, in which case (A) Transocean
                  or one of its Subsidiaries shall pay all costs and expenses
                  incurred in connection with the defense of such Third Party
                  Claim if Transocean or one of its Subsidiaries is the
                  Indemnifying Party with respect to such Third Party Claim or
                  (B) such costs and expenses shall be included in Transocean's
                  or one of its Subsidiaries' Losses if TODCO or one of its
                  Subsidiaries is the Indemnifying Party with respect to such
                  Third Party Claim; or

                           (ii) with respect to which both parties hereto, or
                  TODCO and one or more of its Subsidiaries, or Transocean and
                  one or more of its Subsidiaries may be Indemnifying Parties,
                  and to which paragraph (i) above does not apply and as to
                  which, in the good faith judgment of the General Counsel of
                  Transocean the portion of the aggregate Liability that

                                       26
<PAGE>

                  is the responsibility of Transocean and any of its
                  Subsidiaries (after taking into account indemnification
                  obligations hereunder) equals or exceeds the portion of such
                  Liability that is the responsibility of TODCO and any of its
                  Subsidiaries.

                  (c) A party's right to defend any Third Party Claim pursuant
to Section 3.8(b) includes the right (after consultation with the other party
following at least five Business Days' written notice thereof) to compromise,
settle or consent to the entry of any judgment or determination of liability
concerning such Third Party Claim; provided, however, that the Indemnifying
Party shall not compromise, settle or consent to the entry of judgment or
determination of liability concerning any Third Party Claim without prior
written approval by the Indemnitee (which may not be unreasonably withheld) if
the terms or conditions of such compromise, settlement or consent would, in the
reasonable judgment of the Indemnitee, have a material adverse financial impact
or a material adverse effect upon the ongoing operations of the Indemnitee.
Notwithstanding any other provision of this Section 3.8, unless otherwise agreed
to by the parties in writing (which agreement may not be unreasonably withheld),
no party shall enter into any compromise or settlement or consent to the entry
of any judgment which does not include as an unconditional term thereof the
giving by the third party of a release of both the Indemnitee and the
Indemnifying Party from all further liability concerning such Third Party Claim.

                  (d) If the party having the right to elect to defend a
particular Third Party Claim pursuant to Section 3.8(b) elects, or is deemed to
have elected, not to defend a particular Third Party Claim, the other party may
defend such Third Party Claim without any prejudice to its rights to
indemnification from the Indemnifying Party pursuant to this Article III. In
such case, (i) such other party shall have the right to compromise, settle or
consent to the entry of any judgment with respect to such Third Party Claim as
provided in Section 3.8(c) and (ii) the amount of such compromise, settlement or
judgment shall be determinative of the amount of the Loss (but such compromise,
settlement or judgment shall not necessarily be determinative of which party
hereunder is entitled to indemnification).

                  (e) The Indemnifying Party shall bear all costs and expenses
of defending any Third Party Claim; provided, however, that (A) if Transocean
elects to defend any Third Party Claim or series of related Third Party Claims
pursuant to the last sentence of Section 3.8(b) and Transocean is not an
Indemnifying Party with respect thereto, TODCO shall reimburse Transocean
promptly upon demand by Transocean for all out-of-pocket costs and expenses
reasonably incurred in connection with Transocean's defense of such Third Party
Claim and (B) if both parties may be Indemnifying Parties with respect to such
Third Party Claim, the non-defending party shall reimburse the defending party
promptly upon demand by the defending party for the non-defending party's
proportionate share, allocated based on each party's proportionate
responsibility for the Indemnifiable Loss pursuant to this Agreement, of all
out-of-pocket costs and expenses reasonably incurred in connection with the
defending party's defense of such Third Party Claim.

                  (f) The non-defending party shall make available to the
defending party and its counsel all employees, books and records,
communications, documents, items or matters within its knowledge, possession or
control that are necessary, appropriate or reasonably deemed

                                       27
<PAGE>

relevant by the defending party with respect to such defense; provided, however,
that subject to Section 7.7 hereof, nothing in this subparagraph (f) shall be
deemed to require a party to make available books and records, communications,
documents or items which (i) in such party's good faith judgment could result in
a waiver of any Privilege or (ii) such party is not permitted to make available
because of any Law or any confidentiality obligation to a third party, in which
case such party shall use its reasonable commercial efforts to seek a waiver of
or other relief from such confidentiality restriction.

                  (g) Upon final judgment, determination, settlement or
compromise of any Third Party Claim, and unless otherwise agreed by the parties
in writing, the Indemnifying Party shall pay promptly on behalf of the
Indemnitee, or to the Indemnitee in reimbursement of any amount theretofore
required to be paid by it, all amounts required to be paid by the Indemnifying
Party pursuant to this Article III with respect to such claim as determined by
such final judgment, determination, settlement or compromise.

         3.9 ADDITIONAL MATTERS.

                  (a) Any claim on account of a Loss which does not result from
a Third Party Claim shall be asserted by written notice given by the Indemnitee
to the related Indemnifying Party. Any such notice shall describe the claim in
reasonable detail. Such Indemnifying Party shall have a period of 30 days after
the receipt of such notice within which to respond thereto. If such Indemnifying
Party does not respond within such 30-day period, such Indemnifying Party shall
be deemed to have refused to accept responsibility to make payment. If such
Indemnifying Party does not respond within such 30-day period or rejects such
claim in whole or in part, such Indemnitee shall be free to pursue such remedies
as may be available to such party as contemplated by this Agreement and the
Ancillary Agreements.

                  (b) In the event of payment by or on behalf of any
Indemnifying Party to any Indemnitee in connection with any Third Party Claim,
such Indemnifying Party shall be subrogated to and shall stand in the place of
such Indemnitee in respect of any rights, defenses or claims of such Indemnitee
relating to such Third Party Claim. Such Indemnitee shall cooperate with such
Indemnifying Party in a reasonable manner in prosecuting any subrogated right,
defense or claim, and its out-of-pocket costs and expenses in connection
therewith shall be reimbursed by the Indemnifying Party.

                  (c) In the event of an Action in which the Indemnifying Party
is not a named defendant, if either the Indemnified Party or Indemnifying Party
shall so request, the parties shall endeavor to substitute the Indemnifying
Party for the named defendant, if reasonably practicable. If such substitution
or addition cannot be achieved for any reason or is not requested, the named
defendant shall allow the Indemnifying Party to manage the Action as set forth
in this Article III.

                  (d) THE PARTIES UNDERSTAND AND AGREE THAT THE RELEASE FROM
LIABILITIES AND INDEMNIFICATION OBLIGATIONS HEREUNDER AND UNDER THE ANCILLARY
AGREEMENTS MAY INCLUDE RELEASE FROM LIABILITIES AND INDEMNIFICATION FOR LOSSES
RESULTING FROM, OR ARISING OUT OF, DIRECTLY OR INDIRECTLY, AN INDEMNIFIED
PARTY'S OWN NEGLIGENCE OR STRICT LIABILITY.

                                       28
<PAGE>

         3.10 CONTRIBUTION. If any indemnification provided for in this Article
III is unavailable to an Indemnitee in respect of any Loss arising out of or
related to information contained in the IPO Registration Statement as provided
in Section 3.3(d) or 3.4(d), then the Indemnifying Party, in lieu of
indemnifying such Indemnitee, shall contribute to the amount paid or payable by
such Indemnitee as a result of such Loss, in such proportion as is appropriate
to reflect the relative fault of TODCO and each other member of the TODCO Group,
on the one hand, and Transocean and each other member of the Transocean Group,
on the other hand, in connection with the statements or omissions which resulted
in such Loss. With respect to any Loss relating to matters covered by Section
3.3(d) or otherwise relating to misstatements or omissions under securities or
antifraud laws, the relative fault of a member of the TODCO Group, on the one
hand, and of a member of the Transocean Group, on the other hand, 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 a member of the TODCO Group or a member of the
Transocean Group and was supplied by such member (taking into account the
proviso to Section 3.3(d)).

         3.11 REMEDIES CUMULATIVE. The remedies provided in this Article III
shall be cumulative and, subject to the provisions of Article VI, shall not
preclude assertion by any Indemnitee of any other rights or the seeking of any
and all other remedies against any Indemnifying Party.

         3.12 SURVIVAL OF INDEMNITIES. The rights and obligations of each of
Transocean and TODCO and their respective Indemnitees under this Article III
shall survive the sale or other transfer by any party of any Assets or
businesses or the assignment by it of any Liabilities.

         3.13 INDEMNIFICATION OF DIRECTORS AND OFFICERS. For purpose of Sections
3.3 through 3.12, inclusive, and notwithstanding anything to the contrary
contained in this Agreement, Persons who serve as officers or directors of both
TODCO and Transocean shall be deemed both TODCO Indemnitees and Transocean
Indemnitees.

                                   ARTICLE IV

                       THE IPO AND ACTIONS PENDING THE IPO

         4.1 TRANSACTIONS PRIOR TO THE IPO. Subject to the conditions specified
in Section 4.3, Transocean, Transocean Holdings and TODCO shall use their
reasonable commercial efforts to consummate the IPO. Such efforts shall include,
but not necessarily be limited to, those specified in this Section 4.1 (to the
extent not previously accomplished):

                  (a) TODCO has filed the IPO Registration Statement, and shall
use its best efforts to cause such IPO Registration Statement to become
effective, including by filing such amendments thereto as may be necessary or
appropriate, responding promptly to any comments of the Commission and taking
such other action in that connection as may be reasonably requested by
Transocean. Transocean, Transocean Holdings and TODCO shall also cooperate in
preparing, filing with the Commission and causing to become effective a
registration statement registering the TODCO Common Stock under the Exchange
Act, and any registration statements or amendments thereof which are required to
reflect the establishment of, or amendments to, any

                                       29
<PAGE>

employee benefit and other plans necessary or appropriate in connection with the
IPO, any Prior Transfers, the Separation or the other transactions contemplated
by this Agreement.

                  (b) TODCO, Transocean Holdings and Transocean shall enter into
an underwriting agreement with the underwriters named in the IPO Registration
Statement (the "Underwriting Agreement"), in form and substance reasonably
satisfactory to Transocean, and shall comply with its obligations thereunder.

                  (c) Transocean, Transocean Holdings and TODCO shall consult
with each other and the Underwriters regarding the timing, pricing and other
material matters with respect to the IPO, it being understood that decisions on
such matters may be dictated by Transocean in its sole discretion.

                  (d) TODCO shall take all such action as may be necessary or
appropriate under state securities and blue sky laws of the United States (and
any comparable laws under any foreign jurisdictions) in connection with the IPO.

                  (e) TODCO shall prepare, file and seek to make effective, an
application for listing of the TODCO Class A Common Stock issued in the IPO on
the NYSE, subject to official notice of issuance.

         4.2 COOPERATION. TODCO and Transocean Holdings shall, at Transocean's
direction, promptly take any and all actions necessary or desirable to
consummate the IPO as contemplated by the IPO Registration Statement and the
Underwriting Agreement. Notwithstanding anything to the contrary contained
herein, as between Transocean, Transocean Holdings and TODCO, Transocean may in
its sole discretion choose to terminate, abandon or amend any aspect of the IPO,
and TODCO and Transocean Holdings shall take all actions directed by Transocean
in that regard.

         4.3 CONDITIONS PRECEDENT TO CONSUMMATION OF THE IPO. The parties hereto
shall use their reasonable commercial efforts to satisfy the conditions listed
below for the consummation of the IPO as soon as practicable. The obligations of
the parties to use their reasonable commercial efforts to consummate the IPO
shall be conditioned on the satisfaction, or waiver by Transocean, of the
following conditions:

                  (a) The IPO Registration Statement shall have been filed and
declared effective by the Commission, and there shall be no stop order in effect
with respect thereto.

                  (b) The actions and filings with regard to state securities
and blue sky laws of the United States (and any comparable laws under any
foreign jurisdictions) described in Section 4.1(d) shall have been taken and,
where applicable, have become effective or been accepted.

                  (c) The TODCO Class A Common Stock to be issued in the IPO

                                       30
<PAGE>

                  (e) Transocean shall be satisfied, in its sole discretion,
that (1) following the IPO, Transocean and other members of the Transocean Group
will collectively own stock of TODCO representing control of TODCO, within the
meaning of Section 368(c) of the Code and (2) to Transocean's actual knowledge
(with no duty to investigate), all other conditions to permit the Distribution
to qualify as a tax-free distribution to Transocean, TODCO and Transocean's
shareholders shall, to the extent applicable as of the time of the IPO, be
satisfied, and there shall be no event or condition that is likely to cause any
of such conditions not to be satisfied as of the time of the Distribution or
thereafter.

                  (f) Any material Governmental Approvals necessary to
consummate the IPO shall have been obtained and be in full force and effect.

                  (g) No order, injunction or decree issued by any court or

preventing the consummation of the Separation or the IPO or any of the other
transactions contemplated by this Agreement or any Ancillary Agreement shall be
in effect.

                  (h) Such other actions as the parties hereto may, based upon
the advice of counsel, reasonably request to be taken prior to the IPO in order
to assure the successful completion of the IPO shall have been taken.

                  (i) This Agreement and all Ancillary Agreements shall have
been executed and shall not have been terminated.

                  (j) Pricing committees designated by the Board of Directors of
each of Transocean and Transocean Holdings shall have determined that the terms
of the IPO are acceptable to Transocean and Transocean Holdings, respectively.

                                   ARTICLE V

                     CORPORATE GOVERNANCE AND OTHER MATTERS

         5.1 CHARTER AND BYLAWS. As of the IPO Closing Date, the Amended and
Restated Certificate of Incorporation and Bylaws of TODCO shall be in the forms
of Schedule 5.1(a) and 5.1(b), respectively, with such changes therein as may be
agreed to in writing by Transocean.

         5.2 RIGHTS PLAN AMENDMENTS. Following the IPO Closing Date and for so
long as Transocean beneficially owns shares representing at least 15% of the
voting power of all of the outstanding shares of the TODCO Voting Stock, without
the prior written consent of Transocean, TODCO shall not amend or modify the
TODCO Rights Plan.

         5.3 CHARTER/BYLAW AMENDMENTS. So long as Transocean owns shares
representing at least 15% of the voting power of all of the outstanding shares
of TODCO Voting Stock, TODCO will not, without the prior consent of Transocean,
adopt any amendments to its Amended and Restated Certificate of Incorporation or
Bylaws or take or recommend to its stockholders any action during the term of
this Agreement which would (i) impose limitations on the legal rights of
Transocean or any other member of the Transocean Group or any transferee of any
securities of TODCO from Transocean or a member of the Transocean Group (a

                                       31
<PAGE>

"Transocean Transferee") as a stockholder of TODCO other than those imposed
pursuant to the express terms of this Agreement or the forms of TODCO's Amended
and Restated Certificate of Incorporation and Bylaws attached hereto as
Schedules 5.1(a) and 5.1(b), respectively, including, without limitation, any
action which would impose restrictions (A) based upon the size of security
holding, the business in which a security holder is engaged or other
considerations applicable to Transocean or any other member of the Transocean
Group or a Transocean Transferee and not to security holders generally, (B) by
means of the issuance of or proposal to issue any class of securities having
voting power disproportionately greater than the equity investment in TODCO
represented by such securities or (C) involving impairment of rights granted to
any member of the Transocean Group, (ii) involve the issuance or corporate
action providing for the issuance of any warrant, right, capital stock or other
security (A) which is, or under specified circumstances will become, convertible
into or represent the right to acquire any securities of Transocean or any other
member of the Transocean Group or a Transocean Transferee or (B) which is
dependent upon the amount of voting securities owned by Transocean or any other
member of the Transocean Group or a Transocean Transferee, (iii) deny any
benefit to Transocean or any other member of the Transocean Group or a
Transocean Transferee proportionately as holders of any class of voting
securities generally, or (iv) alter voting or other rights of the holders of any
class of voting securities so that any such rights (or the vote required with
respect to any matter) are determined with reference to the amount of voting
securities held by Transocean or any other member of the Transocean Group or a
Transocean Transferee; provided, that this Section 5.3 shall not prohibit TODCO
from adopting the TODCO Rights Plan or taking any action otherwise prohibited
hereby, so long as Transocean and the other members of the Transocean Group and
any Transocean Transferee are, either expressly or as part of a class of
stockholders which includes Transocean and the other members of the Transocean
Group, together with the Transocean Transferees, exempted from such action or
the limitations on legal rights imposed thereby.

         5.4 TODCO BOARD REPRESENTATION.

                  (a) Beginning on the IPO Closing Date, and for so long as the
Transocean Group beneficially owns shares representing less than a majority but
at least 10% of the voting power of all of the outstanding shares of TODCO
Voting Stock, Transocean shall have the right to designate for nomination by the
TODCO Board (or any nominating committee thereof) to the TODCO Board a
proportionate number of members of the TODCO Board, as calculated in accordance
with this Section 5.4.

                  (b) For so long as the Transocean Group beneficially owns
shares representing at least 10% of the voting power of all of the outstanding
shares of TODCO Voting Stock, Transocean shall be entitled to present to the
TODCO Board or any nominating committee thereof such number of designees of
Transocean (each, a "Transocean Designee") for election to the TODCO Board (or
if there is a classified board, the class of directors up for election) as would
result in Transocean having the appropriate number of Transocean Designees on
the TODCO Board as determined pursuant to Section 5.4(a). TODCO shall exercise
all authority under applicable law and shall use its best efforts to cause each
Transocean Designee to be elected to the TODCO Board effective as of the IPO
Closing Date (or at the first regularly scheduled meeting thereafter).

                                       32

<PAGE>

                  (c) TODCO shall at all such times exercise all authority under
applicable law and use its best efforts to cause all such designees to be
nominated as Board members by the nominating committee of the TODCO Board if
there is such a committee. TODCO shall cause each Transocean Designee for
election to the TODCO Board to be included in the slate of designees recommended
by the TODCO Board to holders of TODCO Common Stock (including at any special
meeting of stockholders held for the election of directors) and shall use its
best efforts to cause the election of each such Transocean Designee, including
soliciting proxies in favor of the election of such persons. In the event that
any Transocean Designee elected to the TODCO Board shall cease to serve as a
director for any reason, the vacancy resulting therefrom shall be filled by the
TODCO Board with a substitute Transocean Designee, unless such vacancy was
caused by action of stockholders (in which case, in accordance with TODCO's
Amended and Restated Certificate of Incorporation, the stockholders shall fill
such vacancy). In the event that as a result of any increase in the size of the
TODCO Board, Transocean is entitled to have one or more additional Transocean
Designees elected to the TODCO Board pursuant to Section 5.4(a), the Transocean
Board shall appoint the appropriate number of such additional Transocean
Designees, unless such increase in size of the TODCO Board was caused by the
action of stockholders (in which case, in accordance with TODCO's Amended and
Restated Certificate of Incorporation, the stockholders shall elect such
additional director or directors).

                  (d) If at any time that Transocean Designees are serving on
the TODCO Board, the Transocean Group beneficially owns shares representing at
least 10% of the total voting power of all of the outstanding shares of TODCO
Voting Stock, the number of persons Transocean shall be entitled to designate
for nomination by the TODCO Board (or any nominating committee thereof) for
election to the TODCO Board shall be equal to the number of directors computed
using the following formula (rounded to the nearest whole number): the product
of (1) the percentage of the voting power of all of the outstanding shares of
TODCO Voting Stock beneficially owned by the Transocean Group and (2) the number
of directors then on the TODCO Board (assuming no vacancies exist).
Notwithstanding the foregoing, if the Transocean Group beneficially owns shares
of TODCO Common Stock representing less than a majority of the total voting
power of all outstanding shares of TODCO Voting Stock and the calculation of the
formula set forth in the foregoing sentence would result in Transocean being
entitled to elect a majority of the members of the TODCO Board, the formula will
be recalculated with the product being rounded down to the nearest whole number;
provided, however, that if the Transocean Group at any time, acquires additional
shares of TODCO Common Stock so that the Transocean Group beneficially owns
shares of TODCO Common Stock representing a majority of the total voting power
of all of the outstanding shares of TODCO Voting Stock, then the number of
persons Transocean shall be entitled to designate for nomination by the TODCO
Board (or any nominating committee thereof) for election to the TODCO Board
shall be adjusted upward, if appropriate as a result of rounding, in accordance
with the provisions of this Section 5.4(d). If the number of Transocean
Designees serving on the TODCO Board exceeds the number determined pursuant to
the foregoing sentences of this Section 5.4(d) (such difference being herein
called the "Excess Director Number"), then Transocean in its sole discretion
shall instruct a number of Transocean Designees (the number of which designees
shall be equal to the Excess Director Number) to resign from the TODCO Board,
and, to the extent such persons do not so resign, Transocean shall assist TODCO
in increasing the size of the TODCO Board, so that after giving effect to such
increase, the number

                                       33
<PAGE>

of Transocean Designees on the TODCO Board is in accordance with the provisions
of this Section 5.4(d).

                  (e) For so long as the Transocean Group beneficially owns
shares representing at least a majority of the voting power of all of the
outstanding shares of TODCO Voting Stock, Transocean shall have the right to
designate the chairman of the TODCO Board. TODCO shall exercise all authority
under applicable law and shall use its best efforts to cause the person
designated by Transocean to be elected as chairman of the TODCO Board.

         5.5 COMMITTEES. Effective as of the IPO Closing Date and for so long as
the Transocean Group owns shares of TODCO Common Stock representing a majority
of the total voting power of all of the outstanding shares of TODCO Voting
Stock, any committee of the Board of Directors of TODCO shall be composed of
directors at least a majority of which are Transocean Designees. Effective as of
the IPO Closing Date and for so long as the Transocean Group beneficially owns
shares of TODCO Common Stock representing less than a majority but more than 10%
of the total voting power of all of the outstanding shares of TODCO Voting
Stock, each committee of the TODCO Board of Directors shall, unless Transocean
consents otherwise, include at least one Transocean Designee to the extent
permitted by Law or stock exchange requirement.

         5.6 SUBSCRIPTION RIGHT.

                  (a) TODCO hereby grants to Transocean, on the terms and
conditions set forth herein, a continuing right (the "Subscription Right") to
purchase from TODCO, at the times set forth herein:

                           (i) with respect to the issuance of a class or series
                  of shares of TODCO Voting Stock, the number of such shares as
                  is necessary to allow Transocean to maintain its Voting
                  Percentage, and

                           (ii) with respect to the issuance of a class or
                  series of shares of TODCO Non-Voting Stock, the number of such
                  shares as is necessary to allow Transocean to maintain its
                  Ownership Percentage with respect to such class or series of
                  shares (or, in the case of a class or series not outstanding
                  prior to such issuance, 80% of the total number of shares of
                  such class or series being issued).

The Subscription Right shall be assignable, in whole or in part and from time to
time, by Transocean to any member of the Transocean Group. The exercise price
for each share of TODCO Stock purchased pursuant to an exercise of the
Subscription Right shall be: (i) in the event of the issuance by TODCO of TODCO
Stock in exchange for cash consideration, the per share price paid to TODCO for
shares of the TODCO Stock issued by TODCO in the related Issuance Event; and
(ii) in the event of the issuance by TODCO of TODCO Stock for consideration
other than cash, the per share Market Price of such TODCO Stock at the Issuance
Event Date of such issuance.

                  (b) The provisions of Section 5.6(a) hereof notwithstanding,
the Subscription Right granted pursuant to Section 5.6(a) shall not apply and
shall not be exercisable in

                                       34
<PAGE>

connection with the issuance by TODCO of any shares of TODCO Common Stock
pursuant to any stock option or other executive or employee benefit or
compensation plan maintained by TODCO, to the extent such issuance would not
result in Transocean and other members of the Transocean Group losing collective
control of TODCO within the meaning of Section 368(c) of the Code. The
Subscription Right granted pursuant to Section 5.6(a) shall terminate if at any
time the Voting Percentage, or the Ownership Percentage with respect to any
class or series of TODCO Non-Voting Stock, is less than 80%.

                  (c) At least 20 Business Days prior to the issuance of any
shares of TODCO Stock (other than pursuant to any stock option or other
executive or employee benefit or compensation plan maintained by TODCO in the
circumstances described in Section 5.6(b) above and other than issuances of
TODCO Stock to any member of the Transocean Group) or the first date on which
any event could occur that, in the absence of a full or partial exercise of the
Subscription Right, would result in a reduction in the Voting Percentage, a
reduction in any Ownership Percentage or the issuance of any shares of a class
or series of TODCO Non-Voting Stock not outstanding prior to such issuance,
TODCO will notify Transocean in writing (a "Subscription Right Notice") of any
plans it has to issue such shares or the date on which such event could first
occur. Each Subscription Right Notice must specify the date on which TODCO
intends to issue such additional shares of TODCO Stock or on which such event
could first occur (such issuance or event being referred to herein as an
"Issuance Event" and the date of such issuance or event as an "Issuance Event
Date"), the number of shares TODCO intends to issue or may issue and the other
terms and conditions of such Issuance Event.

                  (d) The Subscription Right may be exercised by Transocean (or
any member of the Transocean Group to which all or any part of the Subscription
Right has been assigned) for a number of shares equal to or less than the number
of shares the Transocean Group is entitled to purchase pursuant to Section
5.6(a). The Subscription Right may be exercised at any time after receipt of an
applicable Subscription Right Notice and prior to the applicable Issuance Event
Date by the delivery to TODCO of a written notice to such effect specifying (i)
the number of shares of TODCO Stock to be purchased by Transocean, or any member
of the Transocean Group, and (ii) a determination of the exercise price for such
shares. Upon any such exercise of the Subscription Right, TODCO will, prior to
the applicable Issuance Event Date, deliver to Transocean (or any member of the
Transocean Group designated by Transocean), against payment therefor,
certificates (issued in the name of Transocean or its permitted assignee
hereunder or as directed by Transocean) representing the shares of TODCO Stock
being purchased upon such exercise. Payment for such shares shall be made by
wire transfer or intrabank transfer of immediately-available funds to such
account as shall be specified by TODCO, for the full purchase price of such
shares.

                  (e) Except as provided in Section 5.6(f), any failure by
Transocean to exercise the Subscription Right, or any exercise for less than all
shares purchasable under the Subscription Right, in connection with any
particular Issuance Event shall not affect Transocean's right to exercise the
Subscription Right in connection with any subsequent Issuance Event; provided,
however, that the Voting Percentage and any Ownership Percentage following such
Issuance Event in connection with which Transocean so failed to exercise such
Subscription Right in full or in part shall be recalculated as set forth in
Section 1.110 or Section 1.66, respectively.

                                       35
<PAGE>

                  (f) The Subscription Right, or any part thereof, assigned to
any member of the Transocean Group other than Transocean, shall terminate in the
event that such member ceases to be a Subsidiary of Transocean for any reason
whatsoever.

         5.7 TAX-FREE SPIN-OFF. At any time after the IPO Closing Date, if
Transocean advises TODCO that it intends to pursue a tax-free distribution under
Section 355 of the Code or any corresponding provision of any successor statute
or that it intends to otherwise distribute all or a portion of the capital stock
of TODCO beneficially owned by Transocean to its securityholders by way of
dividend, exchange or otherwise (any of the foregoing, a "Distribution"), TODCO
agrees to take all action requested by Transocean to facilitate such transaction
(including without limitation internal restructurings and continuation of
businesses necessary to achieve such tax-free distribution), at TODCO's own
expense. In the event a registration statement is filed in connection with such
transaction, TODCO and Transocean will cooperate to take actions analogous (to
the extent applicable) to those set forth in the Registration Rights Agreement
with respect to a Demand Registration and in particular the parties will
indemnify and provide contribution to each other in a manner analogous to that
set forth in Section 8 of the Registration Rights Agreement.

         5.8 NO VIOLATIONS.

                  (a) So long as the Transocean Group owns shares representing
at least a majority of the voting power of all of the outstanding shares of
TODCO Voting Stock, TODCO covenants and agrees that it will not (i) take any
action or enter into any commitment or agreement which may reasonably be
anticipated to result, with or without notice and with or without lapse of time
or otherwise, in a contravention or event of default by it or any of its
Affiliates of (A) any provisions of applicable Law, including but not limited to
provisions pertaining to the Code or the Employee Retirement Income Security Act
of 1974, as amended, (B) any provision of Transocean's Memorandum of Association
or Articles of Association or (C) any credit agreement or other material
agreement (including agreements relating to covenants not to compete) binding
upon Transocean or (ii) enter into any commitment or agreement that contains
provisions that trigger a default or require a material payment when Transocean
exercises its rights to convert the TODCO Class B Common Stock.

                  (b) TODCO and Transocean agree to provide to each other any
information and documentation requested by the other for the purpose of
evaluating and ensuring compliance with Section 5.8(a).

         5.9 APPLICABILITY OF RIGHTS TO PARENT IN THE EVENT OF AN ACQUISITION.
In the event TODCO merges into, consolidates, sells substantially all of its
assets to or otherwise becomes an Affiliate of a Person (other than Transocean),
pursuant to a transaction or series of related transactions in which Transocean
receives equity securities of such Person (or of any Affiliate of such Person)
in exchange for TODCO Common Stock held by Transocean, all of the rights of
Transocean set forth in this Article V and in Section 7.5 shall continue in full
force and effect and shall apply to the Person the equity securities of which
are received by Transocean pursuant to such transaction or series of related
transactions (it being understood that all other provisions of this Agreement
will apply to TODCO notwithstanding this Section 5.9). TODCO agrees that,
without the consent of Transocean, it will not enter into any agreement which
will have the effect

                                       36
<PAGE>

set forth in the first clause of the preceding sentence, unless such Person
agrees to be bound by the foregoing provision.

         5.10 OTHER MATTERS. TODCO covenants and agrees that it will not, and
will not permit any of its Affiliates to, enter into any commitment or agreement
that binds or purports to bind Transocean or any of its Affiliates.

                                   ARTICLE VI

                         ARBITRATION; DISPUTE RESOLUTION

         6.1 AGREEMENT TO ARBITRATE. Except as otherwise specifically provided
in any Ancillary Agreement, the procedures for discussion, negotiation and
arbitration set forth in this Article VI shall apply to all disputes,
controversies or claims (whether sounding in contract, tort or otherwise) that
may rise out of or relate to, or arise under or in connection with this
Agreement or any Ancillary Agreement, or the transactions contemplated hereby or
thereby (including all actions taken in furtherance of the transactions
contemplated hereby or thereby on or prior to the date hereof), or (for a period
of ten years after the date hereof) the commercial or economic relationship of
the parties relating hereto or thereto, between or among any member of the
Transocean Group and the TODCO Group. Each party agrees on behalf of itself and
each member of its respective Group that the procedures set forth in this
Article VI shall be the sole and exclusive remedy in connection with any
dispute, controversy or claim relating to any of the foregoing matters and
irrevocably waives any right to commence any Action in or before any
Governmental Authority, except as expressly provided in Section 6.7(b) and
except to the extent provided under the Arbitration Act in the case of judicial
review of arbitration results or awards. Each party on behalf of itself and each
member of its respective Group irrevocably waives any right to any trial by jury
with respect to any claim, controversy or dispute set forth in this Section 6.1.

         6.2 ESCALATION.

                  (a) It is the intent of the parties to use their respective
reasonable best efforts to resolve expeditiously any dispute, controversy or
claim between or among them with respect to the matters covered hereby that may
arise from time to time on a mutually acceptable negotiated basis. In
furtherance of the foregoing, any party involved in a dispute, controversy or
claim may deliver a notice (an "Escalation Notice") demanding an in-person
meeting involving representatives of the parties at a senior level of management
of the parties (or if the parties agree, of the appropriate strategic business
unit or division within such entity). A copy of any such Escalation Notice shall
be given to the General Counsel, or like officer or official, of each party
involved in the dispute, controversy or claim (which copy shall state that it is
an Escalation Notice pursuant to this Agreement). Any agenda, location or
procedures for such discussions or negotiations between the parties may be
established by the parties from time to time; provided, however, that the
parties shall use their reasonable best efforts to meet within 30 days of the
Escalation Notice.

                  (b) The parties may, by mutual consent, retain a mediator to
aid the parties in their discussions and negotiations by informally providing
advice to parties. Any opinion

                                       37
<PAGE>

expressed by the mediator shall be strictly advisory and shall not be binding on
the parties, nor shall any opinion expressed by the mediator be admissible in
any arbitration proceedings. The mediator may be chosen from a list of mediators
previously selected by the parties or by other agreement of the parties. Costs
of the mediation shall be borne equally by the parties involved in the matter,
except that each party shall be responsible for its own expenses. Mediation is
not a prerequisite to a demand for arbitration under Section 6.3.

         6.3 DEMAND FOR ARBITRATION.

                  (a) At any time after the first to occur of (i) the date of
the meeting actually held pursuant to the applicable Escalation Notice or (ii)
45 days after the delivery of an Escalation Notice (as applicable, the
"Arbitration Demand Date"), any party involved in the dispute, controversy or
claim (regardless of whether such party delivered the Escalation Notice) may
deliver a notice demanding arbitration of such dispute, controversy or claim (a
"Arbitration Demand Notice"). In the event that any party shall deliver an
Arbitration Demand Notice to another party, such other party may itself deliver
an Arbitration Demand Notice to such first party with respect to any related
dispute, controversy or claim with respect to which the Applicable Deadline has
not passed without the requirement of delivering an Escalation Notice. No party
may assert that the failure to resolve any matter during any discussions or
negotiations, the course of conduct during the discussions or negotiations or
the failure to agree on a mutually acceptable time, agenda, location or
procedures for the meeting, in each case, as contemplated by Section 6.2, is a
prerequisite to a demand for arbitration under this Section 6.3. In the event
that any party delivers an Arbitration Demand Notice with respect to any
dispute, controversy or claim that is the subject of any then pending
arbitration proceeding or of a previously delivered Arbitration Demand Notice,
all such disputes, controversies and claims shall be resolved in the arbitration
proceeding for which an Arbitration Demand Notice was first delivered unless the
arbitrator in his or her sole discretion determines that it is impracticable or
otherwise inadvisable to do so.

                  (b) Except as may be expressly provided in any Ancillary
Agreement, any Arbitration Demand Notice may be given until one year after the
later of the occurrence of the act or event giving rise to the underlying claim
or the date on which such act or event was, or should have been, in the exercise
of reasonable due diligence, discovered by the party asserting the claim (as
applicable and as it may in a particular case be specifically extended by the
parties in writing, the "Applicable Deadline"). Any discussions, negotiations or
mediations between the parties pursuant to this Agreement or otherwise will not
toll the Applicable Deadline unless expressly agreed in writing by the parties.
Each of the parties agrees on behalf of itself and each member of its Group that
if an Arbitration Demand Notice with respect to a dispute, controversy or claim
is not given prior to the expiration of the Applicable Deadline, as between or
among the parties and the members of their Groups, such dispute, controversy or
claim will be barred. Subject to Sections 6.7(d) and 6.8, upon delivery of an
Arbitration Demand Notice pursuant to Section 6.3(a) prior to the Applicable
Deadline, the dispute, controversy or claim shall be decided by a sole
arbitrator in accordance with the rules set forth in this Article VI.

                                       38
<PAGE>

         6.4 ARBITRATORS.

                  (a) Within 15 days after a valid Arbitration Demand Notice is
given, the parties involved in the dispute, controversy or claim referenced
therein shall attempt to select a sole arbitrator satisfactory to all such
parties.

                  (b) In the event that such parties are not able jointly to
select a sole arbitrator within such 15-day period, such parties shall each
appoint an arbitrator (who need not be disinterested as to the parties or the
matter) within 30 days after delivery of the Arbitration Demand Notice. If one
party appoints an arbitrator within such time period and the other party or
parties fail to appoint an arbitrator within such time period, the arbitrator
appointed by the one party shall be the sole arbitrator of the matter.

                  (c) In the event that a sole arbitrator is not selected
pursuant to paragraph (a) or (b) above, the two arbitrators will, within 30 days
after the appointment of the later of them to be appointed, select an additional
arbitrator who shall act as the sole arbitrator of the dispute. After selection
of such sole arbitrator, the initial arbitrators shall have no further role with
respect to the dispute. In the event that the arbitrators so appointed do not,
within 30 days after the appointment of the later of them to be appointed, agree
on the selection of the sole arbitrator, any party involved in such dispute may
apply to the U.S. District Court for the Southern District of Texas to select
the sole arbitrator, which selection shall be made within 30 days after such
application. Any arbitrator selected pursuant to this paragraph (c) shall be
disinterested with respect to each of the parties and shall be reasonably
competent in the applicable subject matter.

                  (d) The sole arbitrator selected pursuant to paragraph (a),
(b) or (c) above will set a time for the hearing of the matter, which will
commence no later than 90 days after the date of appointment of the sole
arbitrator pursuant to paragraph (a), (b) or (c) above and which hearing will be
no longer than 30 days (unless in the judgment of the arbitrator the matter is
unusually complex and sophisticated and thereby requires a longer time, in which
event such hearing shall be no longer than 90 days). The final decision of such
arbitrator will be rendered in writing to the parties not later than 60 days
after the last hearing date, unless otherwise agreed by the parties in writing.

                  (e) The place of any arbitration hereunder will be Houston,
Texas, unless otherwise agreed by the parties.

         6.5 HEARINGS. Within the time period specified in Section 6.4(d), the
matter shall be presented to the arbitrator at a hearing by means of written
submissions of memoranda and verified witness statements, filed simultaneously,
and responses, if necessary in the judgment of the arbitrator or both the
parties. If the arbitrator deems it to be essential to a fair resolution of the
dispute, live cross-examination or direct examination may be permitted, but is
not generally contemplated to be necessary. The arbitrator shall actively manage
the arbitration with a view to achieving a just, speedy and cost-effective
resolution of the dispute, claim or controversy. The arbitrator may, in his or
her discretion, set time and other limits on the presentation of each party's
case, its memoranda or other submissions, and refuse to receive any proffered
evidence, which the arbitrator, in his or her discretion, finds to be
cumulative, unnecessary, irrelevant or of low probative nature. Except as
otherwise set forth herein, any arbitration hereunder will be

                                       39
<PAGE>

conducted in accordance with the procedures of CPR Institute for Dispute
Resolution ("CPR"). The decision of the arbitrator will be final and binding on
the parties, and judgment thereon may be had and will be enforceable in any
court having jurisdiction over the parties. Arbitration awards will bear
interest at an annual rate of the Prime Rate plus 2% per annum, subject to any
maximum amount permitted by applicable law. To the extent that the provisions of
this Agreement and the prevailing rules of the CPR conflict, the provisions of
this Agreement shall govern.

         6.6 DISCOVERY AND CERTAIN OTHER MATTERS.

                  (a) Any party involved in a dispute subject to this Article VI
may request limited document production from the other party or parties of
specific and expressly relevant documents, with the reasonable expenses of the
producing party incurred in such production paid by the requesting party. Any
such discovery (which right to documents shall be substantially less than
document discovery rights prevailing under the Federal Rules of Civil Procedure)
shall be conducted expeditiously and shall not cause the hearing provided for in
Section 6.5 to be adjourned except upon consent of all parties involved in the
applicable dispute or upon an extraordinary showing of cause demonstrating that
such adjournment is necessary to permit discovery essential to a party to the
proceeding. Depositions, interrogatories or other forms of discovery (other than
the document production set forth above) shall not occur except by consent of
the parties involved in the applicable dispute. Disputes concerning the scope of
document production and enforcement of the document production requests will be
determined by written agreement of the parties involved in the applicable
dispute or, failing such agreement, will be referred to the arbitrator for
resolution. All discovery requests will be subject to the parties' rights to
claim any applicable privilege. The arbitrator will adopt procedures to protect
the proprietary rights of the parties and to maintain the confidential treatment
of the arbitration proceedings (except as may be required by law). Subject to
the foregoing, the arbitrator shall have the power to issue subpoenas to compel
the production of documents relevant to the dispute, controversy or claim.

                  (b) The arbitrator shall have full power and authority to
determine issues of arbitrability but shall otherwise be limited to interpreting
or construing the applicable provisions of this Agreement or any Ancillary
Agreement, and will have no authority or power to limit, expand, alter, amend,
modify, revoke or suspend any condition or provision of this Agreement or any
Ancillary Agreement; it being understood, however, that the arbitrator will have
full authority to implement the provisions of this Agreement or any Ancillary
Agreement, and to fashion appropriate remedies for breaches of this Agreement
(including interim or permanent injunctive relief); provided that the arbitrator
shall not have (i) any authority in excess of the authority a court having
jurisdiction over the parties and the controversy or dispute would have absent
these arbitration provisions or (ii) any right or power to award punitive or
treble damages (provided that this clause (ii) shall not limit the award of
damages for any Losses). It is the intention of the parties that in rendering a
decision the arbitrator give effect to the applicable provisions of this
Agreement and the Ancillary Agreements and follow applicable law (it being
understood and agreed that this sentence shall not give rise to a right of
judicial review of the arbitrator's award).

                                       40
<PAGE>

                  (c) If a party fails or refuses to appear at and participate
in an arbitration hearing after due notice, the arbitrator may hear and
determine the controversy upon evidence produced by the appearing party.

                  (d) Arbitration costs will be borne equally by each party
involved in the matter, except that each party will be responsible for its own
attorney's fees and other costs and expenses, including the costs of witnesses
selected by such party.

         6.7 CERTAIN ADDITIONAL MATTERS.

                  (a) Any arbitration award shall be an award with a holding for
or against a party and shall include findings as to facts, issues or conclusions
of law (including with respect to any matters relating to the validity or
infringement of patents or patent applications) and shall include a statement of
the reasoning on which the award rests. The award must also be in adequate form
so that a judgment of a court may be entered thereupon. Judgment upon any
arbitration award hereunder may be entered in any court having jurisdiction
thereof.

                  (b) Prior to the time at which an arbitrator is appointed
pursuant to Section 6.4, any party may seek one or more temporary restraining
orders or other injunctive relief in a court of competent jurisdiction if
necessary in order to preserve and protect the status quo. Neither the request
for, nor the grant or denial of, any such temporary restraining order or other
injunctive relief shall be deemed a waiver of the obligation to arbitrate as set
forth herein, and the arbitrator may dissolve, continue or modify any such
order. Any such temporary restraining order or other injunctive relief shall
remain in effect until the first to occur of the expiration of the order in
accordance with its terms or the dissolution thereof by the arbitrator.

                  (c) Except as required by law, the parties shall hold, and
shall cause their respective officers, directors, employees, agents and other
representatives to hold, the existence, content and result of mediation or
arbitration in confidence in accordance with the provisions of Section 7.13 and
except as may be required in order to enforce any award. Each of the parties
shall request that any mediator or arbitrator comply with such confidentiality
requirement.

                  (d) In the event that at any time the sole arbitrator shall
fail to serve as an arbitrator for any reason, the parties shall select a new
arbitrator who shall be disinterested as to the parties and the matter in
accordance with the procedures set forth herein for the selection of the initial
arbitrator. The extent, if any, to which testimony previously given shall be
repeated or as to which the replacement arbitrator elects to rely on the
stenographic record (if there is one) of such testimony shall be determined by
the replacement arbitrator.

         6.8 CONTINUITY OF SERVICE AND PERFORMANCE. Unless otherwise agreed in
writing, the parties will continue to provide service and honor all other
commitments under this Agreement and each Ancillary Agreement during the course
of dispute resolution pursuant to the provisions of this Article VI with respect
to all matters not subject to such dispute, controversy or claim.

         6.9 LAW GOVERNING ARBITRATION PROCEDURES. The interpretation of the
provisions of this Article VI, only insofar as they relate to the agreement to
arbitrate and any procedures pursuant thereto, shall be governed by the
Arbitration Act and other applicable federal law. In

                                       41
<PAGE>

all other respects, the interpretation of this Agreement shall be governed as
set forth in Section 8.3.

                                   ARTICLE VII

                           COVENANTS AND OTHER MATTERS

         7.1 OTHER AGREEMENTS. In addition to the specific agreements, documents
and instruments annexed to this Agreement, Transocean, Transocean Holdings and
TODCO agree to execute or cause to be executed by the appropriate parties and
deliver, as appropriate, such other agreements, instruments and other documents
as may be reasonably requested and necessary or desirable in order to effect the
purposes of this Agreement and the Ancillary Agreements.

         7.2 FURTHER INSTRUMENTS. At the request of any of TODCO, Transocean
Holdings or Transocean and without further consideration, the other party will
execute and deliver, and will cause its applicable Subsidiaries to execute and
deliver, to the requesting party and its Subsidiaries such other instruments of
transfer, conveyance, assignment, substitution and confirmation and take such
action as the requesting party may reasonably deem necessary or desirable in
order more effectively to transfer, convey and assign to the requesting party
and its Subsidiaries and confirm the requesting party's and its Subsidiaries'
title to all of the assets, rights and other things of value contemplated to be
transferred to the requesting party and its Subsidiaries pursuant to this
Agreement, the Ancillary Agreements, any documents referred to therein and any
Prior Transfers, to put the requesting party and its Subsidiaries in actual
possession and operating control thereof and to permit the requesting party and
its Subsidiaries to exercise all rights with respect thereto (including, without
limitation, rights under contracts and other arrangements as to which the
consent of any third party to the transfer thereof shall not have previously
been obtained). At the request of any of TODCO, Transocean Holdings or
Transocean and without further consideration, the other party will execute and
deliver, and will cause its applicable Subsidiaries to execute and deliver, to
the requesting party and its Subsidiaries all instruments, assumptions,
novations, undertakings, substitutions or other documents and take such other
action as the requesting party may reasonably deem necessary or desirable in
order to have the other party fully and unconditionally assume and discharge the
Liabilities contemplated to be assumed by such party under this Agreement, any
Ancillary Agreement, any document in connection herewith or the Prior Transfers
and to relieve the TODCO Group or the Transocean Group, as applicable, of any
liability or obligation with respect thereto and evidence the same to third
parties. Neither Transocean, Transocean Holdings nor TODCO shall be obligated,
in connection with the foregoing, to expend money other than reasonable
out-of-pocket expenses, attorneys' fees and recording or similar fees.
Furthermore, each party, at the request of another party hereto, shall execute
and deliver such other instruments and do and perform such other acts and things
as may be necessary or desirable for effecting completely the consummation of
the transactions contemplated hereby or by the Prior Transfers.

         7.3 PROVISION OF CORPORATE RECORDS.

                  As soon as practicable after the IPO Closing Date, subject to
the provisions of this Section 7.3, and subject to the provisions of the
Transition Services Agreement, Transocean shall

                                       42
<PAGE>

use all reasonable commercial efforts to deliver or cause to be delivered to
TODCO all TODCO Books and Records in the possession of Transocean or any of its
Subsidiaries, and TODCO shall use all reasonable commercial efforts to deliver
or cause to be delivered to Transocean all Transocean Books and Records in the
possession of TODCO or any of its Subsidiaries. The foregoing shall be limited
by the following:

                  (a) To the extent any document (including computer tape) can
be subdivided without unreasonable effort or cost into two portions, one of
which constitutes an TODCO Book and Record and the other of which constitutes a
Transocean Book and Record, such document (including computer tape) shall be so
subdivided and the appropriate portions shall be delivered to the parties.

                  (b) "Reasonable commercial efforts" shall require only
deliveries of (i) specific and discrete books and records or a reasonably
limited class of items requested by the other party and (ii) specific and
discrete books and records identified by either party in the ordinary course of
business and determined by such party to be material to the other's business.

                  (c) Each party may retain copies of books and records
delivered to the other, subject to holding in confidence in accordance with
Section 7.13 information contained in such books and records.

                  (d) Each party may in good faith refuse to furnish any
Information if it believes in good faith that doing so could adversely affect
its ability to successfully assert a claim of Privilege.

                  (e) Neither party shall be required to deliver to the other
books and records or portions thereof which are subject to any Law or
confidentiality agreements which would by their terms prohibit such delivery;
provided, however, if requested by the other party, such party shall use its
reasonable commercial efforts to seek a waiver of or other relief from such
confidentiality restriction.

         7.4 AGREEMENT FOR EXCHANGE OF INFORMATION. Each of Transocean and TODCO
agrees to provide, or cause to be provided, to each other as soon as reasonably
practicable after written request therefor, any Information in the possession or
under the control of such party that the requesting party reasonably needs (i)
to comply with reporting, disclosure, filing or other requirements imposed on
the requesting party (including under applicable securities laws) by a
Governmental Authority having jurisdiction over the requesting party, (ii) for
use in any judicial proceeding or other proceeding or in order to satisfy audit,
accounting, claims, regulatory, litigation or other similar requirements, except
in the case of a dispute subject to this Article VII brought by one party
against another party (which shall be governed by such discovery rules as may be
applicable under Article VII or otherwise), (iii) to comply with its obligations
under this Agreement or any Ancillary Agreement or (iv) in connection with the
ongoing businesses of Transocean or TODCO as it relates to the conduct of such
businesses on or prior to the Reduced Ownership Date, as the case may be;
provided, however, that in the event that any party determines that any such
provision of Information is reasonably likely to be commercially detrimental,
violate any law or agreement, or waive any attorney-client privilege, the
parties shall

                                       43
<PAGE>

take all reasonable measures to permit the compliance with such obligations in a
manner that avoids any such harm or consequence.

                  (a) After the IPO Closing Date, (i) each party shall maintain
in effect at its own cost and expense adequate systems and controls for its
business to the extent necessary to enable the other party to satisfy its
reporting, accounting, audit and other obligations, and (ii) each party shall as
soon as reasonably practicable, provide, or cause to be provided, to the other
party and its Subsidiaries in such form as such requesting party shall request,
at no charge to the requesting party, all financial and other data and
information as the requesting party determines necessary or advisable in order
to prepare its financial statements and reports or filings with any Governmental
Authority.

                  (b) Any Information owned by a party that is provided to a
requesting party pursuant to this Section 7.4 shall be deemed to remain the
property of the providing party. Unless specifically set forth herein, nothing
contained in this Agreement shall be construed as granting or conferring rights
of license or otherwise in any such Information.

                  (c) To facilitate the possible exchange of Information
pursuant to this Section 7.4 and other provisions of this Agreement after the
Reduced Ownership Date, each party agrees to use its reasonable commercial
efforts to retain all Information in its respective possession or control on the
Reduced Ownership Date substantially in accordance with its policies as in
effect on the Reduced Ownership Date (which, for TODCO and its Subsidiaries,
shall be deemed to be Transocean's policies). TODCO shall not amend its or its
Subsidiaries' record retention policies on or prior to the Reduced Ownership
Date without the consent of Transocean. Except as set forth in the Tax Sharing
Agreement, in the event that TODCO amends its retention policy within three (3)
years after the Reduced Ownership Date, TODCO must give thirty days' prior
written notice of such change in the policy to Transocean. No party will
destroy, or permit any of its Subsidiaries to destroy, any Information that
exists on the IPO Closing Date (other than Information that is permitted to be
destroyed under the current record retention policy of such party) without first
using its reasonable commercial efforts to notify the other party of the
proposed destruction and giving the other party the opportunity to take
possession of such Information prior to such destruction.

                  (d) Except as otherwise provided for herein or in any
Ancillary Agreement, no party shall have any liability to any other party in the
event that any Information exchanged or provided pursuant to this Section is
found to be inaccurate (including, without limitation, by misstatement or
omission), in the absence of willful misconduct by the party providing such
Information; provided, that TODCO shall be strictly liable for any untrue
statement or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact required to be stated therein or necessary to
make the statements therein not misleading, with respect to all Information
contained in Information supplied to Transocean in connection with its filings
under the Securities Act and the Exchange Act, the preparation of its financial
statements or the preparation of any other public disclosures (as well as for
the failure to provide such Information). Except as provided in the foregoing
sentence, no party shall have any liability to any other party if any
Information is destroyed or lost after reasonable commercial efforts by such
party to comply with the provisions of Section 7.4(c).

                                       44
<PAGE>

                  (e) The rights and obligations granted under this Section 7.4
are subject to any specific limitations, qualifications or additional provisions
on the sharing, exchange or confidential treatment of Information set forth in
this Agreement and any Ancillary Agreement.

                  (f) Each party hereto shall, except in the case of a dispute
subject to Article VI brought by one party against another party (which shall be
governed by such discovery rules as may be applicable under Article VI or
otherwise), use its reasonable commercial efforts to make available to each
other party, upon written request, (i) the former, current and future directors,
officers, employees, other personnel and agents of such party for fact finding,
consultation and interviews and as witnesses to the extent such Persons may
reasonably be required in connection with any Actions (other than Actions in
which both Transocean or any of its Subsidiaries, on the one hand, and TODCO or
any of its Subsidiaries, on the other hand, as the case may be, are parties and
may reasonably be adverse to one another in such Action) in which the requesting
party may from time to time be involved relating to the conduct of the TODCO
Business or the Transocean Business and (ii) any books, records or other
documents within its control or which it otherwise has the ability to make
available, to the extent that any such person (giving consideration to business
demands of such directors, officers, employees, other personnel and agents) or
books, records or other documents may reasonably be required in connection with
any judicial proceeding or other proceeding in which the requesting party may
from time to time be involved, regardless of whether such judicial proceeding or
other proceeding is a matter with respect to which indemnification may be sought
hereunder. The requesting party shall bear all costs and expenses in connection
therewith.

         7.5 AUDITORS AND AUDITS; ANNUAL, QUARTERLY AND MONTHLY STATEMENTS AND
ACCOUNTING FORECASTS.

                  (a) Each party agrees that, for so long as Transocean and its
Subsidiaries own 50% or more of the voting power of the outstanding shares of
TODCO Voting Stock, and with respect to any financial reporting period during
which TODCO was a Subsidiary of Transocean:

                           (i) To the extent permitted by law, TODCO shall not
                  select a different accounting firm than the firm selected by
                  Transocean to audit its financial statements to serve as its
                  independent certified public accountants (the "TODCO
                  Auditors") for purposes of providing an opinion on its
                  consolidated financial statements without Transocean's prior
                  written consent (which may be withheld in its sole
                  discretion).

                           (ii) TODCO shall use its reasonable commercial
                  efforts to enable the TODCO Auditors to complete their audit
                  such that they will date their opinion on TODCO's audited
                  annual financial statements on the same date that the
                  Transocean Auditors date their opinion on Transocean's audited
                  annual financial statements, and to enable Transocean to meet
                  its timetable for the printing, filing and public
                  dissemination of Transocean's annual financial statements.
                  TODCO shall use its reasonable commercial efforts to enable
                  the TODCO Auditors to complete their quarterly review
                  procedures such that they will provide clearance on TODCO'
                  quarterly

                                       45
<PAGE>

                  financial statements on the same date that the Transocean
                  Auditors provide clearance on Transocean's quarterly financial
                  statements.

                           (iii) TODCO shall provide to Transocean financial
                  information or documents in the possession of TODCO or any of
                  its Subsidiaries as Transocean may reasonably request. TODCO
                  shall provide to Transocean on a monthly basis management and
                  periodic reports related to any such financial information in
                  form and substance consistent with the practice of TODCO as of
                  the date of this Agreement, including without limitation
                  monthly and quarterly management's discussion and analysis
                  reports and quarterly significant issues memorandums. In
                  addition, TODCO shall provide to Transocean on a timely basis
                  all Information that Transocean requires, in its sole
                  discretion, to meet its schedule for the preparation,
                  printing, filing and public dissemination of Transocean's
                  annual and quarterly financial statements. Without limiting
                  the generality of the foregoing, (A) TODCO shall provide all
                  required financial information with respect to TODCO and its
                  Subsidiaries to the TODCO Auditors in a sufficient and
                  reasonable time and in sufficient detail to permit the TODCO
                  Auditors to take all steps and perform all reviews necessary
                  to provide sufficient assistance to the Transocean Auditors
                  with respect to Information to be included or contained in
                  Transocean's annual and quarterly financial statements, and
                  (B) TODCO shall provide to Transocean within seven Business
                  Days after the end of each quarter and of each fiscal year,
                  the unaudited balance sheet, income statement and statement of
                  cash flows of TODCO and its Subsidiaries as at the end of such
                  period; provided, that TODCO shall submit such balance sheets,
                  income statements and statements of cash flows within a
                  different time period requested by Transocean in the event
                  Transocean changes the timing of its earnings releases from
                  such timing as of the date of this Agreement. Transocean shall
                  provide to TODCO on a timely basis all Information that TODCO
                  reasonably requires to meet its schedule for the preparation,
                  printing, filing and public dissemination of TODCO's annual
                  and quarterly financial statements. Without limiting the
                  generality of the foregoing, Transocean will provide all
                  required financial Information with respect to Transocean and
                  its Subsidiaries to the Transocean Auditors in a sufficient
                  and reasonable time and in sufficient detail to permit the
                  Transocean Auditors to take all steps and perform all reviews
                  necessary to provide sufficient assistance to the TODCO
                  Auditors with respect to Information to be included or
                  contained in TODCO's annual and quarterly financial
                  statements.

                           (iv) TODCO shall authorize the TODCO Auditors to make
                  available to the Transocean Auditors both the personnel who
                  performed or are performing the annual audits and quarterly
                  reviews of TODCO and work papers related to the annual audits
                  and quarterly reviews of TODCO, in all cases within a
                  reasonable time prior to the TODCO Auditors' opinion date, so
                  that the Transocean Auditors are able to perform the

                                       46
<PAGE>

                  procedures they consider necessary to take responsibility for
                  the work of the TODCO Auditors as it relates to the Transocean
                  Auditors' report on Transocean's financial statements, all
                  within sufficient time to enable Transocean to meet its
                  timetable for the printing, filing and public dissemination of
                  Transocean's annual and quarterly statements. Similarly,
                  Transocean shall authorize the Transocean Auditors to make
                  available to the TODCO Auditors both the personnel who
                  performed or are performing the annual audits and quarterly
                  reviews of Transocean and work papers related to the annual
                  audits and quarterly reviews of Transocean, in all cases
                  within a reasonable time prior to the Transocean Auditors'
                  opinion date, so that the TODCO Auditors are able to perform
                  the procedures they consider necessary to take responsibility
                  for the work of the Transocean Auditors as it relates to the
                  TODCO Auditors' report on TODCO's financial statements, all
                  within sufficient time to enable TODCO to meet its timetable
                  for the printing, filing and public dissemination of TODCO's
                  annual and quarterly financial statements.

                           (v) TODCO may not change its accounting principles or
                  practices without the prior written consent of Transocean,
                  except for changes which are required by GAAP and as to which
                  there is no discretion on the part of TODCO, if the TODCO
                  Auditors concur with such changes prior to their
                  implementation. TODCO shall give Transocean as much prior
                  notice as reasonably practical of any proposed determination
                  of, or any significant changes in, its accounting estimates or
                  any accounting principles or practices from those in effect on
                  the IPO Closing Date. TODCO will consult with Transocean and,
                  if requested by Transocean, TODCO will consult with the
                  Transocean Auditors with respect thereto.

                           (vi) TODCO shall change its accounting principles or
                  practices if Transocean changes its accounting principles or
                  practices in order to maintain the same accounting principles
                  and practices as Transocean regardless of whether or not such
                  a change in its accounting principles or practices would be
                  required to be disclosed in TODCO's financial statements as
                  filed with the SEC or otherwise publicly disclosed therein;
                  provided that the TODCO Auditors concurred with such change
                  prior to its implementation. Transocean shall give TODCO as
                  much prior notice as reasonably practical of any proposed
                  determination of, or any significant changes in, its
                  accounting estimates, accounting principles or accounting
                  practices from those in effect on the IPO Closing Date.
                  Transocean will consult with TODCO and, if requested by TODCO,
                  Transocean will consult with TODCO's Auditors with respect
                  thereto.

                           (vii) TODCO shall provide to Transocean budget and
                  forecast periodic reports and related information in form and
                  substance consistent with the practice of TODCO at the date of
                  this Agreement or as may otherwise be reasonably requested by
                  Transocean from time to time,

                                       47
<PAGE>

                  including without limitation detailed annual budget
                  information, detailed quarterly forecast information and
                  summary monthly forecast information. TODCO shall provide such
                  reports and information to Transocean on a timely basis which
                  in any event is sufficient to allow Transocean to meet its
                  schedule for the preparation of its own periodic budgets and
                  forecasts.

                           (viii) Nothing in Sections 7.4 and 7.5 shall require
                  TODCO to violate any agreement with any third party regarding
                  the confidentiality of confidential and proprietary
                  information relating to that third party or its business;
                  provided, however, that in the event that TODCO is required
                  under Sections 7.4 and 7.5 to disclose any such information,
                  TODCO shall use all commercially reasonable efforts to seek to
                  obtain such third party's consent to the disclosure of such
                  information. Similarly, nothing in Sections 7.4 and 7.5 shall
                  require Transocean to violate any agreement with any third
                  party regarding the confidentiality of confidential and
                  proprietary information relating to that third party or its
                  business; provided, however, that in the event that Transocean
                  is required under Sections 7.4 and 7.5 to disclose any such
                  information, Transocean shall use all commercially reasonable
                  efforts to seek to obtain such third party's consent to the
                  disclosure of such information.

                  (b) For so long as Transocean beneficially owns shares
representing 20% or more of the voting power of the outstanding share of TODCO
Voting Stock (i) TODCO shall furnish Transocean, within five Business Days after
the end of each month, TODCO's consolidated net income (loss) for purposes of
allowing Transocean to record its share of TODCO's net income (loss), (ii) TODCO
shall furnish Transocean, within seven Business Days after the end of each
month, quarter and fiscal year, the unaudited consolidated balance sheet, income
statement and statement of cash flows of TODCO and its Subsidiaries as at, or
for, as the case may be, the end of such period, (iii) TODCO shall furnish to
Transocean such financial information or documents in the possession of TODCO
and any of its Subsidiaries as Transocean may reasonably request and (iv) TODCO
shall furnish to Transocean on a monthly basis such management and other
periodic reports related to financial information as reasonably requested from
time to time; provided that the information required in subsection (i) above
shall be submitted within a different time period requested by Transocean in the
event Transocean changes the timing of its earnings releases from such timing as
of the date of this Agreement.

         7.6 AUDIT RIGHTS. To the extent any member of the Transocean Group
provides goods or services to any member of the TODCO Group or any member of the
TODCO Group provides goods or services to a member of the Transocean Group under
this Agreement or under any Ancillary Agreement, the company providing such
goods or services (the "Providing Company") shall maintain complete and accurate
books and records relating to costs and charges made to the company receiving
such goods and services (the "Receiving Company"). Books and accounts shall be
maintained in accordance with U.S. generally accepted accounting principles,
consistently applied. Upon 60 days' notice, the Receiving Company shall be
entitled to audit the Providing Company's books and records related to the goods
and services provided, using its own personnel or personnel from its independent
auditing firm. Discrepancies identified as a result of any audit shall be
promptly reconciled between the parties in accordance with any

                                       48
<PAGE>

provisions of the Ancillary Agreement or, if no such provision is applicable, in
accordance with the dispute resolution provisions of this Agreement. Any charge
which is not questioned by the Receiving Company within the calendar year after
the charge was rendered shall be deemed incontestable.

         7.7 PRESERVATION OF LEGAL PRIVILEGES.

                  (a) Transocean and TODCO recognize that the members of their
respective Groups possess and will possess information and advice that has been
previously developed but is legally protected from disclosure under legal
privileges, such as the attorney-client privilege or work product exemption and
other concepts of legal protection ("Privilege"). Each party recognizes that it
shall be jointly entitled to the Privilege with respect to such privileged
information and that each shall be entitled to maintain and use for its own
benefit all such information and advice, but both parties shall ensure that such
information is maintained so as to protect the Privileges with respect to the
other party's interest. Transocean and TODCO agree that their respective rights
and obligations to maintain, preserve, assert or waive any or all Privileges
belonging to either party with respect to the TODCO Business or the Transocean
Business shall be governed by the provisions of this Section 7.7. With respect
to matters relating to the Transocean Business, Transocean shall have sole
authority in perpetuity to determine whether to assert or waive any or all
Privileges, and TODCO shall take no action (or permit any of its Subsidiaries to
take action) without the prior written consent of Transocean that could result
in any waiver of any Privilege that could be asserted by Transocean or any of
its Subsidiaries under applicable Law and this Agreement. With respect to
matters relating to the TODCO Business, TODCO shall have sole authority in
perpetuity to determine whether to assert or waive any or all Privileges, and
Transocean shall take no action (or permit any of its Subsidiaries to take
action) without the prior written consent of TODCO that could result in any
waiver of any Privilege that could be asserted by TODCO or any of its
Subsidiaries under applicable Law and this Agreement. The rights and obligations
created by this Section 7.7 shall apply to all Information as to which
Transocean or TODCO or their respective Subsidiaries would be entitled to assert
or has asserted a Privilege without regard to the effect, if any, of the
Separation ("Privileged Information"). Privileged Information of Transocean
includes but is not limited to (i) any and all Information existing prior to the
Separation regarding the Transocean Business but which after the Separation is
in the possession of TODCO or any of its Subsidiaries; (ii) all communications
subject to a Privilege occurring prior to the Separation between counsel for
Transocean or any of its Subsidiaries (including in-house counsel and former
in-house counsel who are employees of TODCO) and any person who, at the time of
the communication, was an employee of Transocean or any of its Subsidiaries,
regardless of whether such employee is or becomes an employee of TODCO or any of
its Subsidiaries; and (iii) all Information generated, received or arising after
the IPO Closing Date that refers or relates to Privileged Information generated,
received or arising prior to the IPO Closing Date. Privileged Information of
TODCO includes but is not limited to (i) any and all Information generated prior
to the Separation regarding the TODCO Business but which after the Separation is
in the possession of Transocean or any of its Subsidiaries; (ii) all
communications subject to a Privilege occurring prior to the Separation between
counsel for TODCO or any of its Subsidiaries (including in-house counsel and
former in-house counsel who are employees of Transocean or its Subsidiaries) and
any person who, at the time of the communication, was an employee of TODCO or
any of its Subsidiaries, regardless of whether such employee is or becomes an

                                       49
<PAGE>

employee of Transocean or any of its Subsidiaries; and (iii) all Information
generated, received or arising after the IPO Closing Date that refers or relates
to Privileged Information generated, received or arising prior to the IPO
Closing Date.

                  (b) Upon receipt by Transocean or TODCO, as the case may be,
of any subpoena, discovery or other request from any third party that actually
or arguably calls for the production or disclosure of Privileged Information of
the other or if Transocean or TODCO, as the case may be, obtains knowledge that
any current or former employee of Transocean or TODCO, as the case may be, has
received any subpoena, discovery or other request from any third party that
actually or arguably calls for the production or disclosure of Privileged
Information of the other, Transocean or TODCO, as the case may be, shall
promptly notify the other of the existence of the request and shall provide the
other a reasonable opportunity to review the Information and to assert any
rights it may have under this Section 7.7 or otherwise to prevent the production
or disclosure of Privileged Information. Transocean or TODCO, as the case may
be, will not produce or disclose to any third party any of the other's
Information covered by a Privilege under this Section 7.7 unless (A) the other
has provided its express written consent to such production or disclosure, or
(B) a court of competent jurisdiction has entered an order not subject to
interlocutory appeal or review finding that the Information is not entitled to
protection from disclosure under any applicable privilege, doctrine or rule.

                  (c) Transocean's transfer of TODCO Books and Records and other
Information to TODCO, Transocean's agreement to permit TODCO to obtain
Information existing prior to the Separation, TODCO's transfer of Transocean
Books and Records and other Information and TODCO's agreement to permit
Transocean to obtain Information existing prior to the Separation are made in
reliance on Transocean's and TODCO's respective agreements, as set forth in
Section 7.13 and this Section 7.7, to maintain the confidentiality of such
Information and to take the steps provided herein for the preservation of all
Privileges that may belong to or be asserted by Transocean or TODCO, as the case
may be. The access to Information being granted pursuant to Section 7.3 hereof,
the agreement to provide witnesses and individuals pursuant to Section 7.4(f)
hereof and the disclosure to TODCO and Transocean of Privileged Information
relating to the TODCO Business or the Transocean Business pursuant to this
Agreement in connection with the Separation shall not be asserted by Transocean
or TODCO to constitute, or otherwise be deemed, a waiver of any Privilege that
has been or may be asserted under this Section 7.7 or otherwise. Nothing in this
Agreement shall operate to reduce, minimize or condition the rights granted to
Transocean and TODCO in, or the obligations imposed upon Transocean and TODCO
by, this Section 7.7.

         7.8 PAYMENT OF EXPENSES. Transocean or Transocean Holdings shall pay
all underwriting fees, discounts and commissions and any transfer Taxes and any
other direct costs incurred in connection with the IPO. Except as otherwise
provided in this Agreement, the Ancillary Agreements or any other agreement
between the parties relating to the Separation and the IPO, all other
out-of-pocket costs and expenses of the parties hereto in connection with the
preparation of this Agreement and the Ancillary Agreements, the Separation and
the IPO shall be paid by Transocean or Transocean Holdings. Except as may
otherwise be expressly set forth herein or in an Ancillary Agreement, the TODCO
Group and the Transocean Group shall perform their respective obligations under
this Agreement and the Ancillary Agreements at their own respective cost and
expense.

                                       50

         7.9 GOVERNMENTAL APPROVALS. The parties acknowledge that certain of the
transactions contemplated by this Agreement and the Ancillary Agreements are
subject to certain conditions established by applicable government regulations,
orders and approvals ("Existing Authority"). The parties intend to implement
this Agreement, the Ancillary Agreements and the transactions contemplated
thereby consistent with and to the extent permitted by Existing Authority and to
cooperate toward obtaining and maintaining in effect such Governmental Approvals
as may be required in order to implement this Agreement and each of the
Ancillary Agreements as fully as possible in accordance with their respective
terms. To the extent that any of the transactions contemplated by this Agreement
or any Ancillary Agreement require any Governmental Approvals, the parties will
use their reasonable commercial efforts to obtain any such Governmental
Approvals.

         7.10 LETTERS OF CREDIT. After the IPO Closing Date, if any letters of
credit, financial or surety bonds issued by third parties or other similar
financial instruments issued by third parties (collectively, "Surety
Instruments") for the account of TODCO or any of its Subsidiaries issued on
behalf of or for the benefit of the Transocean Business remain outstanding, or
if any Surety Instruments for the account of Transocean or any of its
Subsidiaries issued on behalf of or for the benefit of the TODCO Business remain
outstanding, the party benefiting from the Surety Instruments shall, and shall
cause its Subsidiaries to, use their respective reasonable best efforts to
replace such Surety Instruments as promptly as practicable with substantially
similar Surety Instruments issued for its own account or the account of any of
its Subsidiaries. Following the IPO Closing Date, (i) the party benefiting from
such Surety Instruments shall indemnify and hold harmless the other party's
Group for any Losses arising from or relating to such unreplaced Surety
Instruments as set forth on Section 3.3 or 3.4, as applicable, and (ii) the
party benefiting from such Surety Instruments shall not, and shall not permit
any of its Subsidiaries to, enter into, renew or extend the term of, increase
its obligations under, or transfer to a third party, any loan, lease, contract
or other obligation in connection with which the other party or any of its
Subsidiaries has issued, or caused to be issued, any Surety Instruments which
remain outstanding. The parties hereto agree that neither party nor any of its
respective Subsidiaries will have any obligation to renew any Surety Instruments
issued on behalf of a member of the other party's Group after the expiration of
any such Surety Instruments, provided that nothing in this Section 7.10 shall
prevent a party from renewing any Surety Instrument.

         7.11 GUARANTEE OBLIGATIONS.

                  (a) Transocean and TODCO shall cooperate and TODCO shall use
its reasonable best efforts to terminate, or to cause TODCO, one of its
Subsidiaries, or one of its Affiliates to be substituted in all respects for
Transocean and any of its Subsidiaries in respect of, all obligations of
Transocean or any of its Subsidiaries under any loan, financing, lease, contract
or other obligation (other than Surety Instruments governed by Section 7.10) in
existence as of the IPO Closing Date pertaining to the TODCO Business for which
Transocean or any of its Subsidiaries is or may be liable as guarantor
("Transocean Guarantees"). If such a termination or substitution is not effected
by the IPO Closing Date, (i) TODCO shall indemnify and hold harmless the
Transocean Group for any Losses arising from or relating to Transocean
Guarantees, and (ii) neither Transocean nor any of its Subsidiaries will have
any obligation to renew any Transocean Guarantees after the expiration of such
Transocean Guarantees. To the extent that Transocean or any of its Subsidiaries
have performance obligations under any

                                       51
<PAGE>

Transocean Guarantee, TODCO will use reasonable best efforts to (i) perform such
obligations on behalf of Transocean and its Subsidiaries or (ii) otherwise take
such action as requested by Transocean so as to put Transocean and its
Subsidiaries in the same position as if TODCO, and not Transocean and its
Subsidiaries, had performed or were performing such obligations.

                  (b) Transocean and TODCO shall cooperate and Transocean shall
use its reasonable best efforts to terminate, or to cause Transocean, one of its
Subsidiaries, or one of its Affiliates to be substituted in all respects for
TODCO and any of its Subsidiaries in respect of, all obligations of TODCO or any
of its Subsidiaries under any loan, financing, lease, contract or other
obligation (other than Surety Instruments governed by Section 7.10) in existence
as of the IPO Closing Date pertaining to the Transocean Business for which TODCO
or any of its Subsidiaries is or may be liable as guarantor ("TODCO
Guarantees"). If such a termination or substitution is not effected by the IPO
Closing Date, (i) Transocean shall indemnify and hold harmless the TODCO Group
for any Losses arising from or relating to TODCO Guarantees, and (ii) neither
TODCO nor any of its Subsidiaries will have any obligation to renew any TODCO
Guarantees after the expiration of such TODCO Guarantees. To the extent that
TODCO or any of its Subsidiaries have performance obligations under any TODCO
Guarantee, Transocean will use reasonable best efforts to (i) perform such
obligations on behalf of TODCO and its Subsidiaries or (ii) otherwise take such
action as requested by TODCO so as to put TODCO and its Subsidiaries in the same
position as if Transocean, and not TODCO and its Subsidiaries, had performed or
were performing such obligations.

                  (c) To the extent covenants and agreements contained in any
loan or credit agreement or other financing document in effect on the date of
this Agreement to which any member of the Transocean Group is a party require,
or require such party to cause, any member of the TODCO Group to take or refrain
from taking any action, or provides for a default or event of default if any
member of the TODCO Group takes or refrains from taking any action, such member
of the TODCO Group shall at all times prior to the Reduced Ownership Date, take
or refrain from taking any such action as would result in a breach or violation
of, or a default under, such agreement.

         7.12 CERTAIN NON-COMPETITION PROVISIONS.

                  (a) As an essential consideration for the obligations of
Transocean Holdings and Transocean under this Agreement, including obligations
in connection with any Prior Transfers and the Separation, and in contemplation
of the disposition by Transocean and Transocean Holdings of shares of TODCO
Common Stock in the IPO, TODCO hereby agrees that for so long as the Transocean
Group beneficially owns shares representing a majority of the voting power of
all of the outstanding shares of TODCO Voting Stock, TODCO shall not, and it
shall cause its Affiliates not to, engage in the following businesses and
activities: (i) any offshore (including marine areas in which swamp drilling
barges operate) contract drilling, workover, production or similar services for
oil and gas wells using any type of drilling unit in any geographic location,
including without limitation the following areas: offshore North America
(including without limitation the Gulf of Mexico), offshore South America,
offshore Europe (including without limitation the North Sea), offshore Africa,
offshore Middle East (including without limitation the Mediterranean Sea, the
Red Sea and the Persian Gulf), offshore India, offshore Asia (including without
limitation Southeast Asia), offshore Australia and the Caspian

                                       52
<PAGE>

Sea and (ii) without limiting the generality of the foregoing clause (i), the
ownership, charter, lease, management or operation of any rigs or other
equipment or assets used to provide the services, and conduct the business and
activities, described above in clause (i); provided however, that this Section
7.12(a) shall not restrict TODCO and its Affiliates from engaging in any of the
following businesses and activities: (A) contract drilling, workover, production
or similar services for oil and gas wells using jackup, barge, platform or land
rigs in the following geographic locations: U.S. onshore, U.S. inland water,
U.S. Gulf of Mexico and offshore or onshore Mexico, Trinidad, Venezuela or
Colombia and (B) without limiting the generality of the foregoing clause (A),
the ownership, charter, lease, management or operation of the drilling units
described above in clause (A) used to provide the services, and conduct the
business and activities, described above in clause (A).

                  (b) It is the intention of each of the parties hereto that if
any of the restrictions or covenants contained in this Section 7.12 is held by a
court of competent jurisdiction to cover a geographic area or to be for a length
of time that is not permitted by Law, or is in any way construed by a court of
competent jurisdiction to be too broad or to any extent invalid, such provision
shall not be construed to be null, void and of no effect, but to the extent such
provision would be valid or enforceable under Law, a court of competent
jurisdiction shall construe and interpret or reform this Section 7.12 to provide
for a covenant having the maximum enforceable geographic area, time period and
other provisions (not greater than those contained in this Section 7.12) as
shall be valid and enforceable under such Law. TODCO acknowledges that any
breach of the terms, conditions or covenants set forth in this Section 7.12
shall be competitively unfair and may cause irreparable damage to Transocean
because of the special, unique, unusual and extraordinary character of
Transocean's business, and Transocean's recovery of damages at law will not be
an adequate remedy. Accordingly, each of the parties hereto agrees that for any
breach of the terms, covenants or agreements of this Section 7.12, a restraining
order or an injunction or both may be issued against such person, in addition to
any other rights or remedies Transocean or Transocean Holdings may have.

         7.13 CONFIDENTIALITY.

                  (a) Transocean and TODCO shall hold and shall cause the
members of the Transocean Group and the TODCO Group, respectively, to hold, and
shall each cause their respective officers, employees, agents, consultants and
advisors to hold, in strict confidence and not to disclose or release without
the prior written consent of the other party, any and all Confidential
Information (as defined herein); provided, that the parties may disclose, or may
permit disclosure of, Confidential Information (i) to their respective auditors,
attorneys, financial advisors, bankers and other appropriate consultants and
advisors who have a need to know such information and are informed of their
obligation to hold such information confidential to the same extent as is
applicable to the parties hereto and in respect of whose failure to comply with
such obligations, Transocean or TODCO, as the case may be, will be responsible
or (ii) to the extent any member of the Transocean Group or the TODCO Group is
compelled to disclose any such Confidential Information by judicial or
administrative process or, in the opinion of legal counsel, by other
requirements of law. Notwithstanding the foregoing, in the event that any demand
or request for disclosure of Confidential Information is made pursuant to clause
(ii) above, Transocean or TODCO, as the case may be, shall promptly notify the
other of the existence of such request or demand and shall provide the other a
reasonable opportunity to seek

                                       53
<PAGE>

an appropriate protective order or other remedy, which both parties will
cooperate in seeking to obtain. In the event that such appropriate protective
order or other remedy is not obtained, the party whose Confidential Information
is required to be disclosed shall or shall cause the other party to furnish, or
cause to be furnished, only that portion of the Confidential Information that is
legally required to be disclosed. As used in this Section 7.13, "Confidential
Information" shall mean all proprietary, technical or operational information,
data or material of one party which, prior to or following the IPO Closing Date,
has been disclosed by Transocean or members of the Transocean Group, on the one
hand, or TODCO or members of the TODCO Group, on the other hand, in written,
oral (including by recording), electronic, or visual form to, or otherwise has
come into the possession of, the other, including pursuant to the access
provisions of Section 7.4 hereof or any other provision of this Agreement
(except to the extent that such Information can be shown to have been (a) in the
public domain through no fault of such party (or, in the case of Transocean, any
other member of the Transocean Group or, in the case of TODCO, any other member
of the TODCO Group) or (b) later lawfully acquired from other sources by the
party (or, in the case of Transocean, such member of the Transocean Group or, in
the case of TODCO, such member of the TODCO Group) to which it was furnished;
provided, however, in the case of (b) that such sources did not provide such
Information in breach of any confidentiality obligations).

                  (b) Notwithstanding anything to the contrary set forth herein,
(i) Transocean and the other members of the Transocean Group, on the one hand,
and TODCO and the other members of the TODCO Group, on the other hand, shall be
deemed to have satisfied their obligations hereunder with respect to
Confidential Information if they exercise the same degree of care (but no less
than a reasonable degree of care) as they take to preserve confidentiality for
their own similar Information and (ii) confidentiality obligations provided for
in any agreement between Transocean or any other member of the Transocean Group,
or TODCO or any other members of the TODCO Group, on the one hand, and any
employee of Transocean or any other member of the Transocean Group, or TODCO or
any other members of the TODCO Group, on the other hand, shall remain in full
force and effect. Confidential Information of Transocean or any other member of
the Transocean Group, on the one hand, or TODCO or any other member of the TODCO
Group, on the other hand, in the possession of and used by the other as of the
IPO Closing Date may continue to be used by such Person in possession of the
Confidential Information in and only in the operation of the Transocean Business
or the TODCO Business, as the case may be, and may be used only so long as the
Confidential Information is maintained in confidence and not disclosed in
violation of Section 7.13(a). Such continued right to use may not be transferred
to any third party unless the third party purchases all or substantially all of
the business and assets in which the relevant Confidential Information is used
or employed in one transaction or in a series of related transactions. In the
event that such right to use is transferred in accordance with the preceding
sentence, the transferring party shall not disclose the source of the relevant
Confidential Information.

         7.14 INSURANCE.

                  (a) Except as otherwise provided in any Ancillary Agreement,
the parties intend by this Agreement that each member of the TODCO Group be
successors-in-interest to all rights that such member of the TODCO Group may
have as of the IPO Closing Date as a Subsidiary or Affiliate of Transocean prior
to the IPO Closing Date under any Insurance Policy

                                       54
<PAGE>

or D&O Policy in effect as of the date of this Agreement, including any rights
such member of the TODCO Group may have as an insured or additional named
insured, Subsidiary or Affiliate, to avail itself of any such policy of
insurance as in effect prior to the IPO Closing Date. At the request of TODCO,
Transocean shall take all reasonable steps, including the execution and delivery
of any instruments, to effect the foregoing; provided, however, that Transocean
shall not be required to pay any amounts, waive any rights or incur any
Liabilities in connection therewith.

                  (b) TODCO agrees that it will pay to Transocean the Insurance
Premium Amount (as defined below) per month (prorated on a daily basis for any
partial month) in respect of Insurance Policies under which any member of the
TODCO Group will continue to have coverage following the date hereof during the
period from the date hereof until the date on which all of the members of the
TODCO Group cease to be insured parties under any Insurance Policies; provided
that any portion of the Insurance Premium Amount shall be paid directly to any
third party insurance broker, syndicate or company to the extent Transocean
directs TODCO to do so. The Insurance Premium Amount shall be payable in arrears
by the 10th day of the next succeeding month. The "Insurance Premium Amount"
will initially equal $519,612. Such amount shall be adjusted in the event any
member of the TODCO Group ceases to be an insured party under any Insurance
Policy or in the event of any change in coverage of any member of the TODCO
Group under any Insurance Policy, in each case to equal the TODCO Group's
proportional share of the premiums thereunder as set forth on Schedule 1.39 with
respect to Insurance Policies in effect as of the date of this Agreement and
based upon the actual third party costs of such coverage with respect to any
Insurance Policies issued after the date of this Agreement. In the event of any
change in the terms of any Insurance Policy with respect to any member of the
TODCO Group, or any change in circumstances involving any member of the TODCO
Group (including without limitation, completion of the IPO), which increases the
premiums with respect to such Insurance Policy, TODCO shall be responsible for
all of such increase.

                  (c) Promptly upon receipt of an invoice from Transocean, TODCO
agrees that it will pay one-half of the amount of the premium in respect of the
D&O Policies for the current policy year of such coverages, to the extent that
such amount has not been paid prior to the date of this Agreement. The parties
shall agree upon an allocation of premium amounts between the parties at least
30 days in advance of the coverage commencement date in respect of any future
D&O Policies under which any member of the TODCO Group has coverage. If the
parties fail to reach such an agreement, Transocean shall have no obligation to
renew or secure such coverages on behalf of any member of the TODCO Group. In
the event of any change in the terms of any D&O Policy with respect to any
member of the TODCO Group, or any change in circumstances involving any member
of the TODCO Group (including without limitation, completion of the IPO), which
increases the premiums with respect to such D&O Policy, TODCO shall be
responsible for all of such increase.

                  (d) The parties to this Agreement acknowledge that Transocean
has notified TODCO of the renewal dates for the coverage under each of the
Insurance Policies and the D&O Policies in effect as of the date of this
Agreement under which a member of the TODCO Group is entitled to coverage.
Transocean shall notify TODCO of any change in such renewal dates and of the
renewal dates for the coverage under each Insurance Policy and D&O Policy
obtained

                                       55
<PAGE>

after the date of this Agreement. TODCO will provide written notice to
Transocean at least 120 days prior to the renewal date of coverage in respect of
any Insurance Policy and at least 60 days prior to the renewal date of coverage
in respect of any D&O Policy if (l) TODCO desires that any member of the TODCO
Group remain covered thereunder on the then existing terms of such Insurance
Policy or D&O Policy (an "Insurance Continuation Notice") or (2) TODCO desires
that any member of the TODCO Group remain covered thereunder on the condition
that changes are made to the terms of such Insurance Policy or D&O Policy (a
"Conditional Insurance Continuation Notice"), which changes shall be specified
in reasonable detail in such Conditional Insurance Continuation Notice. In the
event of a Conditional Insurance Continuation Notice, Transocean shall use its
reasonable efforts to seek proposals for Insurance Policies or D&O Policies
reflecting such changes; provided that such changes do not affect the premiums
attributable to or coverage for any member of the Transocean Group. In the event
of any changes affecting the premiums attributable to or coverage for any member
of the TODCO Group under any Insurance Policy or D&O Policy as to which TODCO
has delivered an Insurance Continuation Notice, Transocean shall promptly notify
TODCO of such changes and TODCO shall promptly notify Transocean as to whether
TODCO elects to withdraw such Insurance Continuation Notice.

                  (e) Nothing in this Agreement shall be deemed to restrict any
member of the TODCO Group from acquiring at its own expense any other insurance
policy in respect of any Liabilities or covering any period; provided, however,
that in the event any member of the TODCO Group desires to acquire any other
insurance policy, TODCO shall notify Transocean at least 45 days prior to the
date such member of the TODCO Group acquires such insurance policy and in such
event Transocean shall be permitted to terminate any equivalent coverage of any
member of the TODCO Group under any Insurance Policies or D&O Policies (it being
understood and acknowledged that Transocean may terminate such coverage
notwithstanding any differences in premiums, deductibles, limits or other
terms). Transocean shall use its reasonable efforts to notify TODCO at least 45
days prior to the renewal date for the coverage in respect of any Insurance
Policy and at least 30 days prior to the renewal date for coverage in respect of
any D&O Policy as to which TODCO has delivered an Insurance Continuation Notice
or a Conditional Insurance Continuation Notice of Transocean's election to not
to renew coverage of any member of the TODCO Group and if Transocean receives
proposed terms of coverage or other information after such date and Transocean
elects not to renew such coverage, it shall promptly notify TODCO. Except as
provided in this paragraph, Transocean shall not terminate coverage of any
member of the TODCO Group under any Insurance Policy or any D&O Policy unless
Transocean provides TODCO written notice of such termination at least 90 days
prior to such termination and either (1) a material breach of Section 7.14 by a
member of the TODCO Group has occurred or (2) in the reasonable judgment of
Transocean, claims or other actions by, or the inclusion of any, members of the
TODCO Group under such Insurance Policies or D&O Policies are reasonably likely
to impact future insurance premiums or coverages for members of the Transocean
Group.

                  (f) The parties to this Agreement acknowledge that members of
the TODCO Group shall be responsible for any deductibles and coinsurance for
claims under the Insurance Policies and D&O Policies with respect to members of
the TODCO Group, and members of the Transocean Group shall be responsible for
any deductibles and coinsurance for claims under the Insurance Policies and D&O
Policies with respect to members of the Transocean Group. The

                                       56
<PAGE>

parties to this Agreement further acknowledge that any claims made under any
Insurance Policies or D&O Policies after any applicable coverage limit is met
shall be subject to the limitations on coverage specified in such policies, and
members of the TODCO Group and members of the Transocean Group shall not be
restricted by this Agreement from making claims under such policies under which
such members have coverage prior to any applicable coverage limit being met (for
the sake of clarity, it being understood that claims shall not be restricted by
this Agreement based on a pre-claim allocation of such limit between members of
the TODCO Group and members of the Transocean Group).

                  (g) Each of the parties hereto acknowledges that members of
the TODCO Group will cease to have coverage under the Insurance Policies and the
D&O Policies in effect as of the date of this Agreement (and may cease to have
coverage under any Insurance Policies or D&O Policies obtained thereafter) at
such time as the Transocean Group ceases to beneficially own shares representing
a majority of the voting power of all of the outstanding shares of TODCO Voting
Stock (in which case no prior notice shall be required). In no event shall
Transocean, any other member of the Transocean Group or any Transocean
Indemnitee have any liability or obligation whatsoever to any member of the
TODCO Group in the event that any Insurance Policy, D&O Policy or other contract
or policy of insurance (1) shall be terminated or otherwise cease to be in
effect for any reason (including without limitation in the event the Transocean
Group ceases to beneficially own shares representing a majority of the voting
power of all of the outstanding shares of TODCO Voting Stock (in which case no
prior notice shall be required), but excluding the termination by Transocean of
an Insurance Policy or D&O Policy if Transocean does not validly provide notice
of termination pursuant to paragraph (d) of this Section 7.14), (2) shall be
unavailable or inadequate to cover any Liability of any member of the TODCO
Group for any reason whatsoever or (3) shall not be renewed or extended beyond
the current expiration date. Without limiting the generality of this Section
7.14, in no event shall Transocean be required to renew the coverage under any
Insurance Policy or D&O Policy.

                  (h) Transocean will be responsible for the administration of
claims under the Insurance Policies and D&O Policies with respect to members of
the Transocean Group and for the administration of any Joint Claims and D&O
Claims, including D&O Claims made by TODCO. TODCO will be responsible for the
administration of claims under the Insurance Policies with respect to members of

      Affiliates may exercise their rights under this Section 2 and (2) so long
      as such Permitted Transferee and its Affiliates collectively own a
      majority of the then outstanding shares of Common Stock, there shall be no

contrary, a registration requested by a Holder pursuant to this Section 2 shall
not be deemed to have been effected (and, therefore, not requested for purposes
of Section 2(a)), (i) unless the registration statement filed in connection
therewith has become effective, (ii) if after such registration statement has
become effective, it becomes subject to any stop order, or there is issued an
injunction or other order or decree of the SEC or other governmental agency or
court for any reason other than a misrepresentation or an omission by such
Holder, which injunction, order or decree prohibits or otherwise materially and
adversely affects the offer and sale of the Registrable Securities so registered
prior to the completion of the distribution thereof in accordance with the plan
of distribution set forth in the registration statement or (iii) if the
conditions to closing specified in the purchase agreement or underwriting
agreement entered into in connection with such registration are not satisfied
other than by reason of some act, misrepresentation or omission by a Holder and
are not waived by the purchasers or underwriters.

         (c) In the event that any registration pursuant to this Section 2 shall
involve, in whole or in part, an underwritten offering, Holders owning at least
50.1% of the Fair Market Value of the Registrable Securities to be registered in
connection with such offering shall have the right to designate an underwriter
reasonably satisfactory to the Company as the lead managing underwriter of such
underwritten offering.

         (d) The Company shall have the right to cause the registration of
additional securities for sale for the account of any person (including the
Company) in any registration of Registrable Securities requested by any Holder
pursuant to Section 2(a); provided, however, that if the managing underwriter or
other independent marketing agent for such offering (if any) determines that, in
its opinion, the additional securities proposed to be sold will materially and

                                      -5-
<PAGE>
adversely affect the offering and sale of the Registrable Securities to be
registered in accordance with the intended method or methods of disposition then
contemplated by such Holder only the number or principal amount of such
additional securities, if any (in excess of the number or principal mount of
Registrable Securities), which, in the opinion of such underwriter or agent, can
be so sold without materially and adversely affecting such offering shall be
included such registration. The rights of a Holder to cause the registration of
additional Registrable Securities held by such Holder in any registration of
Registrable Securities requested by another Holder pursuant to Section 2(a)
shall be governed by the agreement of the Holders with respect thereto as
provided in Section 11(a).

      3. Piggyback Registration. If the Company at any time proposes to register
any of its Common Stock or any of its other securities (such Common Stock and
other securities collectively, "Other Securities") under the Securities Act,
whether or not for sale for its own account, in a manner which would permit
registration of Registrable Securities under the Securities Act, it will at such
time give prompt written notice to each Holder of its intention to do so at
least 20 business days prior to the anticipated filing date of the registration
statement relating to such registration. Such notice shall offer each such
Holder the opportunity to include in such registration statement such number of
Registrable Securities as each such Holder may request. Upon the written request
of any such Holder made within 15 business days after the receipt of the
Company's notice (which request shall specify the number of Registrable
Securities intended to be disposed of and the intended method of disposition
thereof), the Company shall effect, in the manner set forth in Section 5, in
connection with the registration of the Other Securities, the registration under
the Securities Act of all Registrable Securities which the Company has been so
requested to register, to the extent required to permit the disposition (in
accordance with such intended methods thereof) of the Registrable Securities so
requested to be registered, provided that:

         (a) if at any time after giving written notice of its intention to
register any securities and prior to the effective date of such registration,
the Company shall determine for any reason not to register or to delay
registration of such securities, the Company may, at its election, give written
notice of such determination to the Holders and, thereupon, (A) in the case of a
determination not to register, the Company shall be relieved of its obligation
to register any Registrable Securities in connection with such registration and
(B) in the case of a determination to delay such registration, the Company shall
be permitted to delay registration of any Registrable Securities requested to be
included in such registration for the same period as the delay in registering
such Other Securities, but, in either such case, without prejudice to the rights
of the Holders under Section 2;

         (b) (i) if the registration referred to in the first sentence of this
Section 3 is to be a registration in connection with an underwritten offering on
behalf of any of the Company, holders of securities (other than Registrable
Securities) of the Company ("Other Holders") or Holders of Registrable
Securities, and the managing underwriter for such offering advises the Company
in writing that, in such firm's opinion, such offering would be materially and
adversely affected by the inclusion therein of Registrable Securities requested
to be included therein pursuant to this Section 3 because such Registrable
Securities are not of the same type, class or series as the securities to be
offered and sold in such offering on behalf of the Company, the Other Holders
and/or the Holders of Registrable Securities, the Company may exclude all such

                                      -6-
<PAGE>
Registrable Securities requested to be included therein pursuant to this Section
3 from such offering.

      (ii) if the registration referred to in the first sentence of this Section
3 is to be a registration in connection with an underwritten primary offering on
behalf of the Company, and the managing underwriter for such offering advises
the Company in writing that, in such firm's opinion, such offering would be
materially and adversely affected by the inclusion therein of the Holder's
Registrable Securities requested to be included therein pursuant to this Section
3 because the number or principal amount of such Registrable Securities,
considered together with the number or principal amount of securities proposed
to be offered by the Company, exceeds the Maximum Marketable Amount, the Company
shall include in such registration (1) first, the lesser of (A) all securities
the Company proposes to sell for its own account ("Company Securities") and (B)
the number or principal amount of Company Securities that represents 80% of the
total number or principal amount of the Maximum Marketable Amount (or the fair
market value of the Maximum Marketable Amount if such Registrable Securities are
not of the same type, class or series as the Company Securities) included in
such registration; (2) second, the lesser of (A) the number or principal amount
of Registrable Securities requested to be included therein pursuant to this
Section 3 and (B) the number or principal amount of such Registrable Securities
that represents 20% of the total number or principal amount of the Maximum
Marketable Amount (or the fair market value of the Maximum Marketable Amount if
such Registrable Securities are not of the same type, class or series as the
Company Securities) included in such registration (in either case, allocated
among the Holders in accordance with the agreement of the Holders with respect
thereto as provided in Section 11(a)) ; and (3) third, the number or principal
amount of securities, if any, requested to be included therein by Other Holders
(in excess of the number or principal amount of Company Securities and such
Registrable Securities) which, in the opinion of such underwriter, can be so
sold without materially and adversely affecting such offering (allocated among
such Other Holders on the basis of the number or principal amount (or the fair
market value of such securities if the securities are not of the same type,
class or series) of the securities requested to be included therein by each such
Other Holder); and

      (iii) if the registration referred to in the first sentence of this
Section 3 is to be a registration in connection with an underwritten secondary
offering on behalf of Other Holders made pursuant to demand registration rights
granted by the Company to such Other Holders or on behalf of a Holder of
Registrable Securities made pursuant to Section 2 of this Agreement (the
"Initiating Holders"), and the managing underwriter for such offering advises
the Company in writing that, in such firm's opinion, such offering would be
materially and adversely affected by the inclusion therein of the Holder's
Registrable Securities requested to be included therein pursuant to this Section
3 because the number or principal amount of such Registrable Securities,
considered together with the number or principal amount of securities proposed
to be offered by the Initiating Holders, exceeds the Maximum Marketable Amount,
the Company shall include in such registration; (1) first, all securities any
such Initiating Holder proposes to sell for its own account (the "Initiating
Holder Securities"); (2) second, the number or principal amount of such
Registrable Securities (in excess of the number or principal amount of
Initiating Holder Securities) which, in the opinion of such underwriter, can be
sold without materially and adversely affecting such offering (allocated among
the Holders in accordance with the agreement of the Holders with respect thereto
as provided in Section 11(a)); and (3) third, the number or

                                      -7-
<PAGE>
principal amount of securities, if any, requested to be included therein by
Other Holders to which clause (1) does not apply or the Company (in excess of
the number or principal amount of Initiating Holder Securities and such
Registrable Securities) which, in the opinion of such underwriter, can be so
sold without materially and adversely affecting such offering (allocated among
such Other Holders and the Company on the basis of the number or principal
amount (or the fair market value of such securities if the securities are not of
the same type, class or series) of the securities requested to be included
therein by each such Other Holder or the Company; and

         (c) the Company shall not be required to effect any registration of
Registrable Securities under this Section 3 incidental to the registration of
any of its securities in connection with stock option or other executive or
employee benefit or compensation plans of the Company; and

         (d) no registration of Registrable Securities effected under this
Section 3 shall relieve the Company of its obligation to effect any registration
of Registrable Securities required of the Company pursuant to Section 2 hereof.

      4. Expenses. The Company agrees to pay all Registration Expenses with
respect to a registration pursuant to this Agreement. All internal expenses of
the Company or a Holder in connection with any offering pursuant to this
Agreement, including, without limitation, the salaries and expenses of officers
and employees, including in-house attorneys, shall be borne by the party
incurring them. All Selling Expenses of the Holders participating in any
registration pursuant to this Agreement shall be borne by such Holders pro rata
based on each Holder's number of Registrable Securities included in such
registration.

      5. Registration and Qualification. If and whenever the Company is required
to use its best efforts to effect the registration of any Registrable Securities
under the Securities Act as provided in Section 2 or 3 hereof, the Company,
shall:

         (a) prepare and file a registration statement under the Securities Act
relating to the Registrable Securities to be offered as soon as practicable, but
in no event later than 30 days (45 days if the applicable registration form is
other than Form S-3) after the date notice is given, and use its best efforts to
cause the same to become effective as soon as practicable thereafter, but in no
event later than 75 days after the date notice is given (90 days if the
applicable registration form is other than Form S-3); provided that, a
reasonable time before filing a registration statement or prospectus, or any
amendments or supplements thereto (other than reports required to be filed by it
under the Exchange Act and the rules and regulations adopted by the SEC
thereunder), the Company will furnish to the Holders and their counsel and other
representatives (including underwriters) for review and comment, copies of all
documents proposed to be filed and provided further, that if Transocean so
requests (i) it and its counsel and other representatives (including
underwriters) may participate in the drafting and preparation of such
registration statement and prospectus and (ii) such information as it believes
may be beneficial to be included in the registration statement and prospectus
for marketing purposes shall be included therein so long as disclosure of such
information (A) is in compliance with applicable law and (B) does not
competitively harm the Company;

                                      -8-
<PAGE>
         (b) prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection therewith as
may be necessary to keep such registration statement effective with respect to
the disposition of all Registrable Securities included therein and to otherwise
comply with the provisions of the Securities Act with respect to the disposition
of all Registrable Securities included therein until the earlier of (i) such
time as all of such Registrable Securities have been disposed of in accordance
with the intended methods of disposition set forth in such registration
statement and (ii) the expiration of nine months after such registration
statement becomes effective; provided, that such nine-month period shall be
extended for such number of days that equals the number of days elapsing from
(A) the date the written notice contemplated by paragraph (f) below is given by
the Company to (B) the date on which the Company delivers to the Holders of
Registrable Securities the supplement or amendment contemplated by paragraph (f)
below; and provided further, that in the case of a registration to permit the
exercise or exchange of Exchangeable Securities for, or the conversion of
Exchangeable Securities into, Registrable Securities, the time limitation
contained in clause (ii) above shall be disregarded to the extent that, in the
written opinion of Transocean's counsel delivered to the Company, such
Registrable Securities are required to be covered by an effective registration
statement under the Securities Act at the time such Registrable Securities are
issued upon exercise, exchange or conversion of Registrable Securities in order
for such Registrable Securities to be freely tradeable by any person who is not
an Affiliate of the Company or Transocean;

         (c) furnish to the Holders and to any underwriter of such Registrable
Securities such number of conformed copies of such registration statement and of
each amendment thereto (in each case including all exhibits), such number of
copies of the prospectus included in such registration statement (including each
preliminary prospectus and any summary prospectus) and of each supplement
thereto, in conformity with the requirements of the Securities Act, and such
other documents, as the Holders or such underwriter may reasonably request in
order to facilitate the public sale of the Registrable Securities, and a copy of
any and all transmittal letters or other correspondence to, or received from,
the SEC or any other governmental agency or self-regulatory body or other body
having jurisdiction (including any domestic or foreign securities exchange)
relating to such offering;

         (d) use its best efforts to register or qualify all Registrable
Securities covered by such registration statement under the securities or blue
sky laws of such jurisdictions (domestic or foreign) as the Holders or any
underwriter of such Registrable Securities shall request, and use its best
efforts to obtain all appropriate registrations, permits and consents required
in connection therewith, and do any and all other acts and things which may be
necessary or advisable to enable the Holders or any such underwriter to
consummate the disposition in such jurisdictions of its Registrable Securities
covered by such registration statement; provided that the Company shall not for
any such purpose be required to register or qualify generally to do business as
a foreign corporation in any jurisdiction wherein it is not so qualified, or to
subject itself to taxation in any such jurisdiction, or to consent to general
service of process in any such jurisdiction;

         (e) (i) use its best efforts to furnish an opinion of counsel for the
Company addressed to the underwriters dated the date of the closing under the
underwriting agreement (if any) (or if such offering is not underwritten, dated
the effective date of the registration

                                      -9-
<PAGE>
statement), and (ii) use its best efforts to furnish a "cold comfort" letter
addressed to the underwriters and each Holder of Registrable Securities included
in such registration (each a "Selling Holder"), if permissible under applicable
accounting practices, and signed by the independent public accountants who have
audited the Company's financial statements included in such registration
statement, in each such case covering substantially the same matters with
respect to such registration statement (and the prospectus included therein) as
are customarily covered in opinions of issuer's counsel and in accountants'
letters delivered to underwriters in underwritten public offerings of securities
and such other matters as the Selling Holders may reasonably request and, in the
case of such accountants' letter, with respect to events subsequent to the date
of such financial statements;

         (f) immediately notify the Selling Holders in writing (i) at any time
when a prospectus relating to a registration pursuant to Section 2 or 3 hereof
is required to be delivered under the Securities Act of the happening of any
event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits 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, (ii) of any request by the SEC or any other regulatory
body or other body having jurisdiction for any amendment of or supplement to any
registration statement or other document relating to such offering, and (iii) of
the issuance by the SEC of any stop order suspending the effectiveness of any
registration statement relating to such offering or the initiation of
proceedings for that purpose and in any such case (i), (ii) or (iii) at the
request of the Selling Holders, promptly prepare and furnish to the Selling
Holders a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such Registrable Securities, such prospectus shall not include 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, in light of the
circumstances under which they are made, not misleading or to remove such stop
order;

         (g) use its best efforts to list all such Registrable Securities
covered by such registration on each securities exchange and inter-dealer
quotation system on which the Common Stock is then listed;

         (h) use its best efforts to list all Registrable Securities covered by
such registration statement on any securities exchange or inter-dealer quotation
system (in each case, domestic or foreign) not described in paragraph (g) above
as the Selling Holders or any underwriter of such Registrable Securities shall
request, and use its best efforts to obtain all appropriate registrations,
permits and consents required in connection therewith, and to do any and all
other acts and things which may be necessary or advisable to effect such
listing;

         (i) to the extent reasonably requested by the lead or managing
underwriters in connection with any underwritten offering, send appropriate
officers of the Company to attend any "road shows" scheduled in connection with
any such registration;

         (j) furnish for delivery in connection with the closing of any offering
of Registrable Securities unlegended certificates representing ownership of the
Registrable

                                      -10-
<PAGE>
Securities being sold in such denominations as shall be requested by the Selling
Holders or the underwriters; and

         (k) use its best efforts to make available to its security holders, as
soon as reasonably practicable (but not more than eighteen months) after the
effective date of the registration statement, an earnings statement which shall
satisfy the provisions of Section 11(a) of the Securities Act and the rules and
regulations promulgated thereunder.

         The Company may require each Selling Holder to furnish the Company with
such information regarding such Selling Holder and pertinent to the disclosure
requirements relating to the registration and the distribution of such
securities as the Company may from time to time reasonably request.

      6. Exchangeable Securities; Spin-off or Exchange Offer. Transocean shall
be entitled, if it intends to offer any options, rights, warrants, debt
securities, preference shares or other securities issued or to be issued by it
or any other person that are exercisable or exchangeable for or convertible into
any Registrable Securities ("Exchangeable Securities"), to register the
Registrable Securities underlying such options, rights, warrants, debt
securities, preference shares or other securities pursuant to (and subject to
the limitations contained in) Section 2 of this Agreement. Transocean shall also
be entitled, if it intends to distribute to the holders of its ordinary shares
or other securities (including any distribution in exchange for Transocean
ordinary shares or other securities), by means of a distribution or exchange
offer, Registrable Securities, to register such Registrable Securities pursuant
to (and subject to the limitations contained in) Section 2 of this Agreement.

      7. Underwriting; Due Diligence.

         (a) If requested by the underwriters for any underwritten offering of
Registrable Securities pursuant to a registration requested under this
Agreement, the Company shall enter into an underwriting agreement, with such
underwriters for such offering, such agreement to contain such representations
and warranties by the Company and such other terms and provisions as are
customarily contained in underwriting agreements with respect to secondary
distributions, including, without limitation, indemnities and contribution
substantially to the effect and to the extent provided in Section 8 hereof and
the provision of opinions of counsel and accountants' letters to the effect and
to the extent provided in Section 5(e) hereof. The Selling Holders on whose
behalf the Registrable Securities are to be distributed by such underwriters
shall be parties to any such underwriting agreement and the representations and
warranties by, and the other agreements on the part of, the Company to and for
the benefit of such underwriters, shall also be made to and for the benefit of
such Selling Holders. Such underwriting agreement shall also contain such
representations and warranties by the Selling Holders on whose behalf the
Registrable Securities are to be distributed as are customarily contained in
underwriting agreements with respect to secondary distributions. The Selling
Holders may require that any additional securities included in an offering
proposed by a Holder be included on the same terms and conditions as the
Registrable Securities that are included therein.

                                      -11-
<PAGE>
         (b) In the event that any registration pursuant to Section 3 shall
involve, in whole or in part, an underwritten offering, the Company may require
the Registrable Securities requested to be registered pursuant to Section 3 to
be included in such underwritten offering on the same terms and conditions as
shall be applicable to the other securities being sold through underwriters
under such registration. If requested by the underwriters for such underwritten
offering, the Selling Holders on whose behalf the Registrable Securities are to
be distributed shall enter into an underwriting agreement with such
underwriters, such agreement to contain such representations and warranties by
the Selling Holders and such other terms and provisions as are customarily
contained in underwriting agreements with respect to secondary distributions,
including, without limitation, indemnities and contribution substantially to the
effect and to the extent provided in Section 8 hereof. Such underwriting
agreement shall also contain such representations and warranties by the Company
and such other person or entity for whose account securities are being sold in
such offering as are customarily contained in underwriting agreements with
respect to secondary distributions.

         (c) In connection with the preparation and filing of each registration
statement registering Registrable Securities under the Securities Act, the
Company shall give the Holders of such Registrable Securities and the
Underwriters, if any, and their respective counsel and accountants, such
reasonable and customary access to its banks and records and such opportunities
to discuss the business of the Company with its officers and the independent
public accountants who have certified the Company's financial statements as
shall be necessary, in the opinion of such Holders and such underwriters or
their respective counsel, to conduct a reasonable investigation within the
meaning of the Securities Act.

      8. Indemnification and Contribution.

         (a) In the case of each offering of Registrable Securities made
pursuant to this Agreement, the Company agrees to indemnify and hold harmless
each Holder, its officers and directors, each underwriter of Registrable
Securities so offered and each person, if any, who controls any of the foregoing
persons within the meaning of the Securities Act, from and against any and all
claims, liabilities, losses, damages, expenses and judgments, joint or several,
to which they or any of them may become subject, under the Securities Act or
otherwise, including any amount paid in settlement of any litigation commenced
or threatened, and shall promptly reimburse them, as and when incurred, for any
reasonable legal or other expenses incurred by them in connection with
investigating any claims and defending any actions, insofar as such losses,
claims, damages, liabilities or actions shall arise out of, or shall be based
upon, any untrue statement or alleged untrue statement of a material fact
contained in the registration statement (or in any preliminary or final
prospectus included therein) or any amendment or supplement thereto, or in any
document incorporated by reference therein, or any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading; provided, however, that the Company
shall not be liable to a particular Holder in any such case to the extent that
any such loss, claim, damage, liability or action arises out of, or is based
upon, any untrue statement or alleged untrue statement, or any omission, if such
statement or omission shall have been made in reliance upon and in conformity
with information relating to such Holder furnished to the Company in writing by
or on behalf of such Holder and identified in such writing as being specifically
for use in the preparation of the registration statement (or in any preliminary
or final prospectus included therein) or any

                                      -12-
<PAGE>
amendment or supplement thereto. Such indemnity shall remain in full force and
affect regardless of any investigation made by or on behalf of a Holder and
shall survive the transfer of such securities. The foregoing indemnity agreement
is in addition to any liability which the Company may otherwise have to each
Holder, any of such Holder's directors or officers, underwriters of the
Registrable Securities or any controlling person of the foregoing; provided,
further, that this indemnity does not apply in favor of any underwriter or
person controlling an underwriter (or if a Selling Holder offers Registrable
Securities directly without an underwriter, the Selling Holder) with respect to
any loss, liability, claim, damage or expense arising out of or based upon any
untrue statement or alleged untrue statement or omission or alleged omission in
any preliminary prospectus if a copy of a final prospectus was not sent or given
by or on behalf of an underwriter (or the Selling Holder, if the Selling Holder
offered the Registrable Securities directly without an underwriter) to the
person asserting such loss, claim, damage, liability or action at or prior to
the written confirmation of the sale of the Registrable Securities as required
by the Securities Act and such untrue statement or omission had been corrected
in such final prospectus.

         (b) In the case of each offering made pursuant to this Agreement, each
Holder of Registrable Securities included in such offering, by exercising its
registration rights hereunder, agrees to indemnify and hold harmless the
Company, its officers and directors and each person, if any, who controls any of
the foregoing within the meaning of the Securities Act (and if requested by the
underwriters, each underwriter who participates in the offering and each person,
if any, who controls any such underwriter within the meaning of the Securities
Act), from and against any and all claims, liabilities, losses, damages,
expenses and judgments, joint or several, to which they or any of them may
become subject, under the Securities Act or otherwise, including any amount paid
in settlement of any litigation commenced or threatened, and shall promptly
reimburse them, as and when incurred, for any legal or other expenses incurred
by them in connection with investigating any claim and defending any actions,
insofar as any such losses, claims, damages, liabilities or actions shall arise
out of, or shall be based upon, any untrue statement or alleged untrue statement
of a material fact contained in the registration statement (or in any
preliminary or final prospectus included therein) or any amendment or supplement
thereto, or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, but in each case only to the extent that such untrue statement of a
material fact is contained in, or such material fact is omitted from,
information relating to such Holder furnished in writing to the Company by or on
behalf of such Holder and identified in such writing as being specifically for
use in the preparation of such registration statement (or in any preliminary or
final prospectus included therein). The foregoing indemnity is in addition to
any liability which such Holder may otherwise have to the Company, any of its
directors or officers, underwriters who participates in the offering or any
controlling person of the foregoing; provided, however, that this indemnity does
not apply in favor of any underwriter or person controlling an underwriter (or
if the Company offers securities directly without an underwriter, the Company)
with respect to any loss, liability, claim, damage or expense arising out of or
based upon any untrue statement or alleged untrue statement or omission or
alleged omission in any preliminary prospectus if a copy of a final prospectus
was not sent or given by or on behalf of an underwriter (or the Company, if the
Company offered the securities directly without an underwriter) to the person
asserting such loss, claim, damage, liability or action at or prior to the
written confirmation of the sale of the

                                      -13-
<PAGE>
securities as required by the Securities Act and such untrue statement or
omission had been corrected in such final prospectus.

         (c) Each party indemnified under Paragraph (a) or (b) of this Section 8
shall, promptly after receipt of notice of any claim or the commencement of any
action against such indemnified party in respect of which indemnity may be
sought, notify the indemnifying party in writing of the claim or the
commencement thereof; provided that the failure to notify the indemnifying party
shall not relieve it from any liability which it may have to an indemnified
party on account of the indemnity agreement contained in paragraph (a) or (b) of
this Section 8, except to the extent the indemnifying party was materially
prejudiced by such failure, and in no event shall relieve the indemnifying party
from any other liability which it may have to such indemnified party. If any
such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein, and, to the extent that it wishes, jointly with any
other similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided that each
indemnified party, its officers and directors, if any, and each person, if any,
who controls such indemnified party within the meaning of the Securities Act,
shall have the right to employ separate counsel reasonably approved by the
indemnifying party to represent them if the named parties to any action
(including any impleaded parties) include both such indemnified party and an
indemnifying party or an Affiliate of an indemnifying party, and such
indemnified party shall have been advised by counsel a conflict may exist
between such indemnified party and such indemnifying party or such Affiliate
that makes representation by the same counsel inadvisable, and in that event the
fees and expenses of one such separate counsel for all such indemnified parties
shall be paid by the indemnifying party. An indemnified party will not enter
into any settlement agreement which is not approved by the indemnifying party,
such approval not to be unreasonably withheld. The indemnifying party may not
agree to any settlement of any such claim or action which provides for any
remedy or relief other than monetary damages for which the indemnifying party
shall be responsible hereunder, without the prior written consent of the
indemnified party, which consent shall not be unreasonably withheld. In any
action hereunder as to which the indemnifying party has assumed the defense
thereof with counsel reasonably satisfactory to the indemnified party, the
indemnified party shall continue to be entitled to participate in the defense
thereof, with counsel of its own choice, but, except as set forth above, the
indemnifying party shall not be obligated hereunder to reimburse the indemnified
party for the costs thereof. In all instances, the indemnified party shall
cooperate fully with the indemnifying party or its counsel in the defense of
such claim or action.

         (d) If the indemnification provided for in this Section 8 shall for any
reason be unavailable to or insufficient to hold harmless an indemnified party
in respect of any loss, claim, damage or liability, or any action in respect
thereof, referred to herein, then each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability, or
action in respect thereof, in such proportion as shall be appropriate to reflect
the relative fault of the

                                      -14-

indemnifying party on the one hand and the indemnified party on the other with
respect to the statements or omissions which resulted in such loss, claim,
damage or liability, or action in respect thereof, as well as any other relevant
equitable considerations. The relative fault shall be determined by reference to
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information related to and
supplied by the indemnifying party on the one hand or the indemnified party on
the other, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission,
but not by reference to any indemnified party's stock ownership in the Company.
In no event, however, shall a Holder be required to contribute in excess of the
amount of the net proceeds received by such Holder in connection with the sale
of Registrable Securities in the offering which is the subject of such loss,
claim, damage or liability. The amount paid or payable by an indemnified party
as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this paragraph shall be deemed to include, for
purposes of this paragraph, any legal or other expenses reasonably incurred by
such indemnifying party in connection with investigating or defending any such
action or claim. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

      9. Rule 144. The Company shall take such measures and file such
information, documents and reports as shall be required by the SEC as a
condition to the availability of Rule 144 (or any successor provision). The
Company shall use its best efforts to cause all conditions to the availability
of Form S-3 (or any successor form thereto) under the Securities Act for the
filing of registration statements under this Agreement to be met as soon as
possible after the completion of the Public Offering.

      10. Holdback.

         (a) Each Holder agrees by the acquisition of Registrable Securities, if
so required by the managing underwriter of any offering of equity securities by
the Company and provided that the Company and each of its executive officers and
directors enter into similar agreements, not to sell, make any short sale of,
loan, grant any option for the purchase of, effect any public sale or
distribution of or otherwise dispose of any Registrable Securities owned by such
Holder, during the 7 days prior to and the 90 days after the registration
statement relating to such offering has become effective (or such shorter period
as may be required by the underwriter), except as part of such underwritten
offering. Notwithstanding the foregoing sentence, each Holder subject to the
foregoing sentence shall be entitled to (i) issue shares of Common Stock or
other securities upon the exercise of an option or warrant or the conversion or
exchange of a security outstanding on such date, (ii) sell any Registrable
Securities acquired in open market transactions after the completion of such
underwritten offering, (iii) sell any Registrable Securities in a transaction in
which the purchaser agrees to be bound by the restrictions contained in the
foregoing sentence and (iv) in the case of Transocean, effect any distribution
of shares of Common Stock to the holders of its ordinary shares by means of a
distribution or exchange offer in a transaction intended to qualify as a
tax-free distribution under Section 355 of the Internal Revenue Code, as
amended, or any corresponding provision of any successor statute. The Company
may legend and may impose stop transfer instructions on any certificate
evidencing Registrable Securities relating to the restrictions provided for in
this

                                      -15-
<PAGE>
Section 10. The Holders shall not be subject to the restrictions set forth in
this Section 10(a) for longer than 97 days during any 12-month period and a
Holder shall no longer be subject to such restrictions at such time as such
Holder together with its Affiliates shall own less than 5% of the then
outstanding shares of Common Stock on a fully-diluted basis.

         (b) The Company agrees, if so required by the managing underwriter of
any offering of Registrable Securities, not to sell, make any short sale of,
loan, grant any option for the purchase of, effect any public sale or
distribution of or otherwise dispose of any of its equity securities during the
30 days prior to and the 90 days after any underwritten registration pursuant to
Section 2 or 3 hereof has become effective, except as part of such underwritten
registration. Notwithstanding the foregoing sentence, the Company shall be
entitled to (i) issue shares of Common Stock or other securities upon the
exercise of an option or warrant or the conversion or exchange of a security
outstanding on such date, (ii) issue shares of Common Stock or other securities
pursuant to Transocean's subscription rights described in the Prospectus, (iii)
grant shares of Common Stock or other securities pursuant to employee benefit
plans in effect on such date and (iv) sell shares of Common Stock or other
securities in a transaction in which the purchaser agrees to be bound by the
restrictions contained in the preceding paragraph. The Company shall use its
best efforts to obtain and enforce similar agreements from any other Persons if
requested by the managing underwriter of such offering. Neither the Company nor
such Persons shall be subject to the restrictions set forth in this Section
10(b) for longer than 120 days during any 12-month period.

      11. Transfer of Registration Rights.

         (a) A Holder may transfer all or any portion of its rights under this
Agreement to any transferee of Registrable Securities that represent (assuming
the conversion, exchange or exercise of all Registrable Securities so
transferred that are convertible into or exercisable or exchangeable for the
Company's Common Stock) at least 10% of the then issued and outstanding Common
Stock of the Company (each, a "Permitted Transferee"); provided, however, that
(i) with respect to any transferee of a majority of the then outstanding shares
of Common Stock, the Company shall not be obligated to file a registration
statement pursuant to a registration request made by such transferee pursuant to
Section 2 hereof on more than two occasions after such time as such transferee
owns less than a majority of the then outstanding shares of Common Stock, (ii)
with respect to any transferee of less than a majority but more than 25% of the
then outstanding shares of Common Stock, the Company shall not be obligated to
file a registration statement pursuant to a registration request made by such
transferee pursuant to Section 2 hereof on more than two occasions, and (iii)
with respect to any transferee of 25% or less of the then issued and outstanding
Common Stock, the Company shall not be obligated to file a registration
statement pursuant to a registration request made by such transferee pursuant to
Section 2 hereof on more than one occasion. No transfer of registration rights
pursuant to this Section shall be effective unless the Company has received
written notice from the Holder of a transfer no later than 10 business days
after the Holder enters into a binding agreement to transfer Registrable
Securities. Such notice shall state the name and address of any Permitted
Transferee and identify the number and/or aggregate principal amount of
Registrable Securities with respect to which the rights under this Agreement are
being transferred and the scope of the rights so transferred. In connection with
any such transfer, the term Transocean as used in this Agreement (other than in
Sections 2(a)(iii) and 5(a)) shall, where appropriate to assign the rights

                                      -16-
<PAGE>
and obligations hereunder to such Permitted Transferee, be deemed to refer to
the Permitted Transferee of such Registrable Securities. Transocean and any
Permitted Transferees may exercise the registration rights hereunder in such
priority, as among themselves, as they shall agree among themselves, and the
Company shall observe any such agreements of which it shall have notice as
provided above.

         (b) After any such transfer, the transferring Holder shall retain its
rights under this Agreement with respect to all other Registrable Securities
owned by such transferring Holder.

         (c) Upon the request of the transferring Holder, the Company shall
execute an agreement with a Permitted Transferee substantially similar to this
Agreement.

      12. Miscellaneous.

         (a) Injunctions. Each party acknowledges and agrees that irreparable
damage would occur in the event that any of the provisions of this Agreement was
not performed in accordance with its specific terms or was otherwise breached.
Therefore, each party shall be entitled to an injunction or injunctions to
prevent breaches of the provisions of this Agreement and to enforce specifically
the terms and provisions hereof in any court having jurisdiction, such remedy
being in addition to any other remedy to which such party may be entitled at law
or in equity.

         (b) Severability. If any term or provision of this Agreement is held by
a court of competent jurisdiction to be invalid, void or unenforceable, the
remainder of the terms and provisions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and
each of the parties shall use its best efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term or provision.

         (c) Further Assurances. Subject to the specific terms of this
Agreement, each of the parties hereto shall make, execute, acknowledge and
deliver such other instruments and documents, and take all such other actions,
as may be reasonably required in order to effectuate the purposes of this
Agreement and to consummate the transactions contemplated hereby.

         (d) Waivers, etc. Except as otherwise expressly set forth in this
Agreement, no failure or delay on the part of either party in exercising any
power or right hereunder shall operate as a waiver thereof, nor shall any single
or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. Except as
otherwise expressly set forth in this Agreement, no modification or waiver of
any provision of this Agreement nor consent to any departure therefrom shall in
any event be effective unless the same shall be in writing and signed by an
authorized officer of each of the parties, and then such waiver or consent shall
be effective only in the specific instance and for the purpose for which given.

         (e) Entire Agreement. This Agreement contains the final and complete
understanding of the parties with respect to its subject matter. This Agreement
supersedes all

                                      -17-

prior agreements and understandings between the parties, whether written or
oral, with respect to the subject matter hereof.

         (f) Counterparts. For the convenience of the parties, this Agreement
may be executed in any number of counterparts, each of which shall be deemed to
be an original but all of which together shall be one and the same instrument.

         (g) Termination. The right of any Holder to request registration or
inclusion in any registration pursuant to this Agreement shall terminate on such
date as all Registrable Securities held or entitled to be held upon conversion
by such Holder and its Affiliates may immediately be sold under Rule 144 during
any ninety (90) day period.

         (h) Amendment. This Agreement may be amended only by a written
instrument duly executed by an authorized officer of each of the parties.

basis more favorable than that set forth in Section 2(d) hereof with respect to
