                          TRANSITION SERVICES AGREEMENT

                  This TRANSITION SERVICES AGREEMENT (the "Agreement") is
entered into as of the __ day of ____, 2003 between Transocean Holdings Inc., a
Delaware corporation ("Transocean Holdings"), and TODCO, a Delaware corporation
("TODCO").

                  WHEREAS, Transocean Inc., a Cayman Islands company
("Transocean"), Transocean Holdings and TODCO currently contemplate that TODCO
will make an initial public offering ("IPO") of shares of TODCO Class A Common
Stock held by Transocean and Transocean Holdings;

                  WHEREAS, TODCO, as a wholly-owned Subsidiary, has previously
received certain administrative and support services from Transocean Holdings
and its Affiliates; and

                  WHEREAS, in order to effect an orderly transition by TODCO to
a separate, stand-alone entity following the IPO, TODCO desires Transocean
Holdings and its Affiliates to provide the services described herein.

                  NOW, THEREFORE, in consideration of the premises and the
agreements set forth in this Agreement, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties, intending to be legally bound hereby, agree as follows:

                                   ARTICLE I
                                  DEFINITIONS

                  SECTION 1.1 Definitions. All capitalized terms used but not
otherwise defined herein shall have the meanings assigned to such terms in the
Master Separation Agreement ("Separation Agreement") entered into as of the date
hereof among Transocean Holdings, TODCO and Transocean.

                                   ARTICLE II
                                    SERVICES

                  SECTION 2.1 Services. Subject to the terms and conditions of
this Agreement, Transocean Holdings, acting through its and/or its Affiliates'
respective employees, agents, contractors or independent third parties, agrees
to provide or cause to be provided to TODCO and its Subsidiaries the services
set forth in Exhibits A-__ hereto (including any additional services provided
pursuant to Section 2.3, all of such services collectively referred to herein as
the "Services). At all times during the performance of the Services, all Persons
performing such Services (including agents, temporary employees, independent
third parties and consultants) shall be construed as being independent from the
TODCO Group and such Persons shall not be considered or deemed to be an employee
of any member of the TODCO Group nor entitled to any employee benefits of TODCO
as a result of this Agreement.

                  SECTION 2.2 Service Coordinators. Each party will nominate a
representative to act as the primary contact Person with respect to the
provision of the Services as contemplated

                                       1

<PAGE>

by this Agreement (the "Service Coordinators"). The initial Service Coordinators
shall be Ricardo Rosa for Transocean Holdings and Scott O'Keefe for TODCO.
Unless Transocean Holdings and TODCO otherwise agree, Transocean Holdings and
TODCO agree that all notices and communications relating to this Agreement other
than those day to day communications and billings relating to the actual
provision of the Services shall be directed to the Service Coordinators in
accordance with Section 11.2 hereof.

                  SECTION 2.3 Additional Services. From the date hereof until 12
months following the IPO Closing Date, TODCO may request additional Services
from Transocean Holdings by providing written notice. Upon mutual agreement as
to the cost, duration and scope of such additional Services, Transocean Holdings
and TODCO may supplement in writing the Exhibits hereto to include such
additional Services.

                  SECTION 2.4 Third Party Services. Transocean Holdings shall
have the right to hire third party subcontractors to provide all or part of any
Service hereunder; provided, that, in the event such subcontracting is
inconsistent with past practices and the practice applied by Transocean
generally from time to time within its own organization, Transocean Holdings
obtain the prior written consent of TODCO, which consent shall not be
unreasonably withheld.

                  SECTION 2.5 Standard of Performance; Limitation of Liability.
The Services to be provided hereunder shall be performed with the same general
degree of care as when performed within the Transocean organization. In the
event Transocean Holdings or its Affiliates fail to provide the Services in
accordance herewith, the sole and exclusive remedy of TODCO shall be to, at
TODCO's sole discretion, either (i) have the Service reperformed, or (ii) not
pay for such Service, or if payment has already been made, receive a refund of
the payment made therefor; provided that in the event Transocean Holdings
defaults in the manner described in Section 7.1(ii), TODCO shall have the
further rights set forth in Section 7.1. EXCEPT AS EXPRESSLY SET FORTH IN THIS
SECTION 2.5, NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, IMPLIED OR EXPRESSED,
ARE MADE BY TRANSOCEAN HOLDINGS OR ITS AFFILIATES WITH RESPECT TO THE SERVICES
UNDER THIS AGREEMENT AND ALL SUCH REPRESENTATIONS OR WARRANTIES ARE HEREBY
WAIVED AND DISCLAIMED. TODCO HEREBY EXPRESSLY WAIVES ANY RIGHT TODCO MAY
OTHERWISE HAVE FOR ANY LOSSES, TO ENFORCE SPECIFIC PERFORMANCE OR TO PURSUE ANY
OTHER REMEDY AVAILABLE IN CONTRACT, AT LAW OR IN EQUITY IN THE EVENT OF ANY
NON-PERFORMANCE, INADEQUATE PERFORMANCE, FAULTY PERFORMANCE OR OTHER FAILURE OR
BREACH BY TRANSOCEAN HOLDINGS OR ITS AFFILIATES UNDER OR RELATING TO THIS
AGREEMENT, NOTWITHSTANDING THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT OR
ACTIVE OR PASSIVE) OR GROSS NEGLIGENCE OF TRANSOCEAN HOLDINGS OR ITS AFFILIATES
OR ANY OTHER PERSON INVOLVED IN THE PROVISION OF SERVICES AND WHETHER DAMAGES
ARE ASSERTED IN CONTRACT OR TORT, UNDER FEDERAL, STATE OR FOREIGN LAWS OR OTHER
STATUTE OR OTHERWISE.

                  SECTION 2.6 Conflict with Laws. Notwithstanding any other
provision hereof, Transocean Holdings shall not be required to provide a Service
to the extent the provision thereof would violate or contravene an applicable
Law. To the extent that the provision of any

                                       2
<PAGE>

such Service would violate an applicable Law, the parties agree to work together
in good faith to provide such Service in a manner which would not violate any
Law.

                                  ARTICLE III

                  SECTION 4.1 Payment. Charges for Services shall be invoiced
monthly by Transocean Holdings or the Transocean Holdings Affiliate providing
the Service. TODCO shall make the corresponding payment no later than 30
calendar days after receipt of the invoice. Each invoice shall be directed to
the TODCO Service Coordinator or such other person designated in writing from
time to time by such Coordinator. The invoice shall set forth in reasonable
detail for the period covered by such invoice: (i) the Services rendered, (ii)
the basis for the calculation of the costs as set forth in Section 3.1 if
applicable, and (iii) such additional information as TODCO may reasonably
request at least 30 days in advance of the billings for a particular Service. In
the event there is any dispute with respect to an invoice, TODCO shall make the
payment for all non-disputed portions in accordance herewith.

                                   ARTICLE V
                                      TERM

                  SECTION 5.1 Term. The term of this Agreement shall commence
upon the [IPO Closing Date] and shall continue in force until the termination of
all Services in accordance with the duration of such Services set forth in the
Exhibits hereto or as otherwise set forth herein.

                                   ARTICLE VI
                           DISCONTINUATION OF SERVICES

                  SECTION 6.1 Discontinuation of Services. Except for those
Services for which a minimum duration has been set in the Exhibits hereto, TODCO
may, with Transocean Holdings' prior written consent, elect to discontinue any
individual Service from time to time. Transocean Holdings may withhold such
consent in its sole discretion.

                                  ARTICLE VII
                                    DEFAULT

                  SECTION 7.1 Termination for Default. In the event (i) of a
failure of TODCO to pay for Services in accordance with the terms of this
Agreement, or (ii) of a failure of Transocean Holdings to perform, or cause to
be performed, the Services in accordance with the terms of this Agreement which
failure results or could reasonably result in a material adverse impact on the
business, operations or financial results of TODCO, then in either case the
non-defaulting party shall have the right, at its sole discretion, to terminate
this Agreement if the defaulting party has (A) failed to cure the default within
30 days of receipt of the written notice

                                       3

of default or, (B) if such default is not reasonably susceptible to cure within
a 30 day period, taken action within 30 days of receipt of the written notice of
default reasonably designed to cure such default as soon as is reasonably
practicable. TODCO's right to terminate this Agreement set forth in (ii) above
and the rights set forth in Section 2.5 shall constitute TODCO's sole and
exclusive rights and remedies for a breach by Transocean Holdings hereunder
(including without limitation any breach caused by an Affiliate of Transocean
Holdings or other third party providing a Service hereunder).

                                  ARTICLE VIII

OR ACTIVE OR PASSIVE) OR GROSS NEGLIGENCE OF THE INDEMNIFIED PARTIES, EXCEPT TO
THE EXTENT SUCH LOSS IS CAUSED BY THE WILLFUL MISCONDUCT OF AN INDEMNIFIED

                  SECTION 8.3 Services Received. TODCO hereby acknowledges and
agrees that:

                  (a) the Services to be provided hereunder are subject to and
         limited by the provisions of Section 2.5 - Standard of Performance,
         Section 7.1 - Termination and the other provisions hereof, including
         without limitation, the limitation of remedies available to TODCO which
         restricts available remedies resulting from a Service not provided in
         accordance with the terms hereof to either non-payment or reperformance
         of such

                                       4

         terminate this Agreement;

                  (b) the Services are being provided solely as a result of the

         extent set forth in Sections 2.5 and 7.1; and

                  (d) a material inducement to Transocean Holdings' agreement to
         provide the Services is the limitation of liability set forth herein
         and the release and indemnity provided by TODCO.

                  ACCORDINGLY, EXCEPT WITH REGARD TO THE LIMITED REMEDIES AND
INDEMNITIES EXPRESSLY SET FORTH HEREIN, TODCO SHALL ASSUME ALL LIABILITY FOR AND
SHALL FURTHER RELEASE, DEFEND, INDEMNIFY AND HOLD THE OTHER PARTY, ITS
AFFILIATES AND THEIR RESPECTIVE EMPLOYEES, OFFICERS, DIRECTORS AND AGENTS (ALL

law or otherwise) without the prior written

                                       6
<PAGE>

consent of the other party; provided however that the foregoing shall in no way
restrict the performance of a Service by an Affiliate of Transocean Holdings or
a third party as otherwise allowed hereunder.

                  SECTION 11.4 No Third Party Beneficiaries. Nothing in this
Agreement, express or implied, is intended to or shall confer upon any Person
(other than TODCO, Transocean Holdings and any Transocean Holdings Affiliate
providing Services hereunder or their respective successors or permitted

whatsoever under or by reason of this Agreement, and no Person (except as so
specified) shall be deemed a third-party beneficiary under or by reason of this
Agreement.

                  SECTION 11.5 Amendment. No amendments, additions to,
alterations, modifications or waivers of all or any part of this Agreement shall
be of any effect, whether by course of dealing or otherwise, unless explicitly
set forth in writing and executed by both parties hereto. If the provisions of
this Agreement and the provisions of any purchase order or order acknowledgment
written in connection with this Agreement conflict, the provisions of this
Agreement shall prevail.

                  SECTION 11.6 Waiver. The waiver by any party hereto of a
breach of any provision of this Agreement shall not operate or be construed as a
waiver of any subsequent breach. The failure of any party to require performance
of any provision of this Agreement shall not affect any party's right to full
performance thereof at any time thereafter.

or the application of any such provision to any Person or circumstance shall be
declared judicially to be invalid, unenforceable or void, such decision shall
not have the effect of invalidating or voiding the remainder of this Agreement,
it being the intent and agreement of TODCO and Transocean Holdings that this
Agreement shall be deemed amended by modifying such provision to the extent
necessary to render it valid, legal and enforceable while preserving its intent
or, if such modification is not possible, by substituting therefor another
provision that is legal and enforceable and that achieves the same objective.

                  SECTION 11.8 Counterparts. This Agreement may be executed in
two or more counterparts, each of which shall be deemed to be an original, but
all of which together shall constitute one agreement binding on TODCO and
Transocean Holdings.

                  SECTION 11.9 Governing Law. This Agreement shall be governed
by, and construed in accordance with, the laws of the State of Texas without

                  SECTION 11.10 Arbitration. All disputes and controversies
which may arise out of or in connection with this Agreement and are not resolved
through good faith negotiation shall be settled by binding arbitration. The
arbitration will take place in Houston, Texas and shall be conducted in
accordance with the procedures of [the Center for Public Resources of New York
("CPR")]. The dispute shall be decided by a single arbitrator selected by the
parties; provided the parties are able to agree as set forth herein. The
arbitration shall be initiated by providing written notice to the other party.
The party so initiating the proceedings shall provide the other

                                       7
<PAGE>

party in writing three (3) names of potential arbitrators within fifteen (15)
days of giving notice to initiate arbitration. The other party will thereafter
have thirty (30) days to either select one of the three individuals or reject
all three (a "Rejection"). Failure to timely respond shall be deemed a
Rejection. Should the parties be unable to agree on a single arbitrator, each
shall choose a single arbitrator within fifteen (15) days of the Rejection by
providing written notice to the other party, and the two (2) arbitrators shall
mutually select the third. The award of the arbitration shall be final and
binding upon both parties and may be enforced in any court of competent
jurisdiction.

                  SECTION 11.11 Relationship of Parties. This Agreement does not
create a fiduciary relationship, partnership, joint venture or relationship of
trust or agency between the parties.

party agrees to execute and deliver such additional documents, and will provide
such additional information and assistance as any party may reasonably require
to carry out the terms of this Agreement.

Holdings and its Affiliates shall, when on the property of TODCO, conform to the
rules and regulations of TODCO concerning safety, health and security which are
made known to such employees in advance in writing.

                  SECTION 11.14 Survival. The parties agree that Articles VIII
and IX will survive the termination of this Agreement and that any such
termination shall not affect any obligation for the payment of Services rendered
prior to termination.

Agreement as of this ___ day of _______, 2003.

otherwise indicated, all "Section" references in this Agreement are to sections
of this Agreement.

                                    RECITALS

         WHEREAS, TODCO is a direct wholly owned subsidiary of Holdings, which
in turn is a direct wholly owned subsidiary of Transocean Inc., a company
organized under the laws of the Cayman Islands ("Transocean"); and

         WHEREAS, the Board of Directors of Transocean has determined that it
would be appropriate and desirable for Transocean to separate the TODCO Tax
Group from the Transocean Tax Group and, in that connection, for each Group to
acquire certain assets from and assume certain liabilities of the other Group;
and

         WHEREAS, the Board of Directors of each of TODCO and Transocean
Holdings has also approved such transactions; and

         WHEREAS, TODCO intends to acquire a portion or all of its outstanding
debt held by Transocean in exchange for newly issued shares of TODCO common
stock, and it is expected that as a result of such exchange TODCO will cease to
be a member of the Holdings Consolidated Group; and

         WHEREAS, Transocean, Holdings and TODCO currently contemplate that
TODCO will make an initial public offering ("IPO") of shares of TODCO Class A
Common Stock held by Transocean and Holdings pursuant to a registration
statement on Form S-1 filed pursuant to the Securities Act; and

         WHEREAS, Transocean wishes to retain the flexibility so that, if
following the IPO Transocean's direct and indirect ownership of the voting power
of all of the outstanding shares of Voting Stock is at least 80%, Transocean may
distribute to the holders of its ordinary shares (including any distribution in
exchange for Transocean ordinary shares or other securities), by means of a
distribution or exchange offer, shares of Voting Stock it then owns in a
transaction intended to qualify as a tax-free distribution under Section 355 of
the Code or any corresponding provision of any successor statute; and

         WHEREAS, the parties set forth in a Master Separation Agreement the
principal arrangements between them regarding the separation of the TODCO Tax
Group from the Transocean Tax Group, the IPO and any distribution; and

                                      -3-

Separate Return Years.

Straddle Period which ends on the IPO Closing Date, such Straddle Period shall
be treated as two Tax Years, one ending on the IPO Closing Date and the other
beginning on the following day, and all calculations shall be made by (x)
closing the books of the TODCO Tax Group at the end of the month preceding the
month in which the IPO Closing Date occurs, (y) closing the books of TODCO Tax
Group again at the end of the month in which the IPO Closing Date occurs, and
(z) apportioning Tax Items accruing in the month in which the IPO Closing Date
occurs to each hypothetical Tax Year pro rata in proportion to the number of
days in such month that are within each hypothetical Tax Year. Notwithstanding
the immediately preceding sentence, all Tax Items that are extraordinary items
within the meaning of Treasury Regulations Section 1.1502-76(b)(2)(ii)(C) shall
be allocated to the hypothetical Tax Year in which they accrue;

                                      -11-
<PAGE>

provided, however, that all extraordinary items accruing after the
Deconsolidation Date and on or before the IPO Closing Date will be allocated
entirely to the hypothetical Tax Year that begins on the day following the IPO
Closing Date.

               (c) Short Years. If a Consolidated or Combined Return is filed
with respect to a Tax Year, and if TODCO and its eligible Subsidiaries are not
included in such Consolidated or Combined Return for that entire Tax Year, then
for purposes of determining the Income Taxes attributable to or imposed on the
TODCO Tax Group for the resulting short Consolidated or Combined Year and the
short Separate Return Year, all calculations shall be made by (x) closing the
books of the TODCO Tax Group at the end of the month preceding the month in
which the first short year ends, (y) closing the books of TODCO Tax Group again
at the end of the month in which the first short year ends, and (z) apportioning
Tax Items accruing in the month in which the first short year ends to each short
year pro rata in proportion to the number of days in such month that are within
each short year. Notwithstanding clause (z) of the immediately preceding
sentence, all Tax Items that are extraordinary items within the meaning of
Treasury Regulations Section 1.1502-76(b)(2)(ii)(C) shall be allocated to the
short year in which they accrue; provided, however, that the principles of
Treasury Regulations Section 1.1502-76(b)(1)(ii)(B) (Next Day Rule) shall apply
in determining the proper allocation of extraordinary items accruing on the last
day of the earlier short Tax Year.

               (d) Payments to Foreign Jurisdictions. If at any time after the
Deconsolidation Date any member of the TODCO Tax Group makes a payment to a
foreign Tax Authority for Taxes for which Holdings is otherwise liable under
this Agreement, Holdings shall have no obligation to indemnify such member
unless such member obtains prior written consent from Holdings to make such
payment. If Holdings fails to consent to such payment, it shall indemnify TODCO
and its Subsidiaries for any Taxes resulting from the failure to make such
payment.

         2.6 Tax Payments and Intercompany Billings. Each Company shall pay the
Taxes allocated to it by this Section 2 either to the applicable Taxing
Authority or to the other appropriate Company in accordance with Section 5.

         SECTION 3. PREPARATION AND FILING OF TAX RETURNS.

         3.1 Combined Returns and Consolidated Returns.

               (a) Preparation by Transocean and Holdings. Holdings shall be
responsible for preparing all Consolidated Returns and Combined Returns.

               (b) Provision of Information and Assistance by TODCO.

                    (i) Information with Respect to Final Returns. TODCO shall,
for each Consolidated Return or Combined Return, provide Holdings with all
information relating to members of the TODCO Tax Group which Holdings needs to
prepare such return. TODCO shall use its best efforts to provide such
information no later than the earlier of (x) thirty days prior to the due date
of such Consolidated Return or Combined Return or (y) the first day of the fifth
month following the end of the Tax

                                      -12-
<PAGE>

Year to which such information relates, but in any event shall provide such
information no later than the earlier of (x) fifteen days prior to the due date
of such Consolidated Return or Combined Return and (y) the fifteenth day of the
fifth month following the end of such Tax Year.

                    (ii) Information with Respect to Estimated Payments and
Extension Payments. TODCO shall provide Holdings with all information relating
to members of the TODCO Tax Group which Holdings needs to determine the amount
of Taxes due on any Payment Date. TODCO shall use its best efforts to provide
such information no later than fifteen days before such Payment Date, but in any
event shall provide such information no later than ten days before such Payment
Date.

                    (iii) Assistance. At the request of Holdings, TODCO shall
take any action (e.g., filing a ruling request with the relevant Tax Authority
or executing a power of attorney) that is reasonably necessary in order for
Holdings to prepare and file any Consolidated or Combined Return.

         3.2 Separate Returns and Other Returns.

               (a) Tax Returns to be Prepared by Holdings. Holdings shall be
responsible for preparing all Separate Returns and Other Returns which either
(x) relate solely to one or more members of the Transocean Tax Group for any Tax
Year or (y) relate solely to one or more members of the TODCO Tax Group for any
Tax Year ending on or before the IPO Closing Date or for any Tax Year which is a
Straddle Period. In connection with the preparation of the Tax Returns specified
in this Section 3.2(a), TODCO shall provide information and assistance as
described in Sections 3.1(b)(ii) and (iii) in the same manner as if such Tax
Returns were Consolidated Returns or Combined Returns.

               (b) Tax Returns to be Prepared by TODCO.

                    (i) Except as otherwise provided in this Section 3.2(b),
TODCO shall be responsible for preparing all Separate Returns and Other Returns
which relate solely to one or more members of the TODCO Tax Group for any Tax
Year ending after the IPO Closing Date and which is not a Straddle Period. In
preparing such Other Returns, TODCO may not take any positions that it knows, or
reasonably should know, would adversely affect any member of the Transocean Tax
Group.

                    (ii) Holdings will have the right to determine the items
specified in clauses (1), (3) and (4) of Section 3.3(a) with respect to any Tax
Return described in Section 3.2(b)(i) if either (x) such Tax Return is filed for
a Tax Year at any time during which Transocean or Holdings owned stock
possessing greater than 50% of the voting power of all of the outstanding TODCO
stock or (y) such Tax Return is filed for a Tax Year during which TODCO has an
obligation under Section 4.2 to pay Holdings for the Tax Benefits realized, if
any, in such Tax Year or a subsequent Tax Year with respect to any Tax Item
created before the IPO Closing Date.

                                      -13-
<PAGE>

               (c) Provision of Information. Holdings shall provide to TODCO,
and TODCO shall provide to Holdings, any information about members of the
Transocean Tax Group or the TODCO Tax Group, respectively, which the party
receiving such information needs to comply with Section 3.2(a) or (b). Such
information shall be provided within the time prescribed by Section 3.1(b) for
the provision of information for Consolidated Returns and Combined Returns.

         3.3 Special Rules Relating to the Preparation of Tax Returns.

               (a) General Rule. Except as otherwise provided in this Agreement,
the party responsible for filing a Tax Return pursuant to Sections 3.1 or 3.2
shall have the exclusive right, in its sole discretion, with respect to such Tax
Return to determine (1) the manner in which such Tax Return shall be prepared
and filed, including the elections, methods of accounting, positions,
conventions and principles of taxation to be used and the manner in which any
Tax Item shall be reported, (2) whether any extensions may be requested, (3) the
elections that will be made on such Tax Return, (4) whether an amended Tax
Return shall be filed, (5) whether any claims for refund shall be made, (6)
whether any refunds shall be paid by way of refund or credited against any
liability for the related Tax and (7) whether to retain outside firms to prepare
or review such Tax Return.

               (b) Election to File Consolidated or Combined Returns. Holdings
shall have the sole discretion of filing any Consolidated Return or Combined
Return, if the filing of such return is elective under the relevant Tax Law.

               (c) Returns Affecting Liability of Other Party. Insofar as a Tax
Return prepared by Holdings may affect Taxes for which TODCO is liable pursuant
to this Agreement, or vice versa:

                    (i) Tax Accounting Practices. The Tax Return shall be
prepared consistently with past Tax accounting practices to the extent
permissible under applicable Tax Law.

                    (ii) Review Prior to Filing. The Company responsible for
preparing any Tax Return (whether Holdings on the one hand or TODCO on the other
hand) shall make the Tax Return or relevant portion thereof available to the
other Company no later than thirty days before the Tax Return is due and shall
in good faith take into account any comments on such Tax Return by the other
Company.

               (d) Standard of Performance. Holdings shall prepare the Tax
Returns for which it is responsible pursuant to this Section 3 and which relate
to the TODCO Tax Group with the same general degree of care as it uses in
preparing Tax Returns relating solely to the Transocean Tax Group. Holdings
shall not be liable for any additional Taxes that result from a redetermination
in a Tax Contest and for which TODCO is otherwise liable under Section 2, unless
such additional Taxes arise solely as a result of Holdings failure to exercise
such degree of care.

                                      -14-

         SECTION 4. TAX BENEFITS, REFUNDS, AND CARRYBACKS.

         4.1 Compensation by Holdings for TODCO's Post-IPO Tax Assets. In the
event that any member of the Transocean Tax Group realizes a Tax Benefit during
any Consolidated Year or Combined Year as a result of the use or absorption by
any Transocean Tax Group member of any Tax Asset of the TODCO Tax Group which
was created after the IPO Closing Date, as determined under the principles of
Section 4.2(b), then Holdings (or other appropriate member of the Transocean Tax
Group) shall pay to TODCO, in accordance with Section 5, the amount of the Tax
Benefit realized by the member of the Transocean Tax Group.

         4.2 Compensation by TODCO for Pre-IPO Tax Assets.

               (a) Payment for Tax Assets. Except as otherwise provided in
Section 4.2(f), if on any Tax Return, any member of the TODCO Tax Group uses or
absorbs any Tax Asset which was created on or before the IPO Closing Date to
reduce any Tax for which it is liable under Section 2, then TODCO shall, in
accordance with Section 5, pay to Holdings (or another member of the Transocean
Tax Group designated by Holdings pursuant to Section 5.5) an amount equal to the
value of such Tax Asset.

               (b) Time at which Tax Asset is Created. For purposes of Section
4.2(a), a Tax Asset shall be considered created in the Tax Year relating to the
Tax Return (including an information return of U.S. persons with respect to
certain foreign corporations on Internal Revenue Service Form 5471) on which the
Tax Asset is first included. However, any Tax Asset not included in a Tax Return
by reason of Sections 163(j) or 267 of the Code, Treasury Regulations Section
1.1502-13 or any similar deferral provision under federal, state or foreign Tax
Law shall be considered included in such Tax Return. A Tax Asset resulting from
foreign income tax shall be considered created in the year in which such tax
accrues, regardless of the year in which such tax is paid.

               (c) Value of Tax Assets. For purposes of Section 4.2(a), the
value of any Tax Asset shall be considered equal to:

                    (i) in the case of any deduction, loss previously deferred
under Section 267(f) of the Code, net operating loss or net capital loss, the
product of (1) the amount of such deduction or loss used or absorbed on such Tax
Return and (2) the highest statutory tax rate applicable under Section 11 of the
Code or relevant state or foreign Tax Law and

                    (ii) in the case of any tax credit, one hundred percent
(100%) of such tax credit used or absorbed on such Tax Return.

               (d) Determination of Tax Assets Used or Absorbed. The
determination of whether any Tax Asset created on or before the IPO Closing Date
has been used or absorbed on any relevant Tax Return after the IPO Closing Date
shall be determined by TODCO and reported by a nationally recognized accounting
firm no later than sixty (60) days after the date on which the relevant Tax
Return is filed. Such

                                      -15-
<PAGE>

accounting firm shall report the Tax Assets it determines are used or absorbed
on the relevant Tax Return by applying the same standards as it would in
preparing a tax return that it would sign as an "income tax return preparer" (as
defined in Section 7701(a)(36) of the Code) and such accounting firm shall sign
a letter certifying that such determination has been made in accordance with
such standards and on a fair and impartial basis. Holdings shall be given an
opportunity to review such determination and the supporting schedules and
calculations. Holdings shall be given the opportunity to ask questions of the
accounting firm, and if Holdings is not satisfied with the detail given in the
supporting schedules, the accounting firm shall provide Holdings with any
additional supporting detail as Holdings shall reasonably request. Holdings
shall have, in its sole discretion, the right to designate a nationally
recognized accounting firm and shall bear all costs associated with such firms
reporting under this Section 4.2(d).

               (e) Forecast of Tax Assets Used or Absorbed. If during any Tax
Year ending after the IPO Closing Date any Tax Asset created on or before the
IPO Closing Date continues to be available for use by any member of the TODCO
Tax Group, then TODCO shall provide Holdings with periodic forecasts of the
anticipated use of such Tax Asset during such year no later than March 15, June
15, September 15 and December 15 of such year. TODCO shall also provide
Holdings, no later than October 15 of such year, a forecast of the expected use
or absorption of any such Tax Asset in the following year.

               (f) Acceleration of Payments Upon Change of Control.
Notwithstanding Section 4.2(a), if on any day following the IPO Closing Date any
person or entity other than a member of the Transocean Tax Group owns stock (or
would be treated as owning stock if the attribution rules of Section 318(a) of
the Code were to apply) possessing greater than 50% of the voting power of all
of the outstanding TODCO stock, TODCO shall, in accordance with Section 5, pay
to Holdings (or another member of the Transocean Tax Group designated by
Holdings pursuant to Section 5.5) the amount equal to the value of all unused
Tax Assets described in Section 4.2(a) as if such Tax Assets had been used or
absorbed by TODCO immediately prior to the day such person or entity first owns
the amount of stock possessing such voting power. If (x) an unused Tax Asset is
treated by this Section 4.2(f) as being used or absorbed and (y) such Tax Asset
is a foreign tax credit under Section 9.01 of the Code, then such Tax Asset
shall be valued under Section 4.2(c)(i) as if it were a deduction rather than
under Section 4.2(c)(ii).

         4.3 Claims for Refund from Carrybacks.

               (a) Filing Claims and Making Payments for Carrybacks. If the
TODCO Tax Group generates a Carryback to a Consolidated Year or Combined Year,
then, upon request of TODCO, Holdings may, in its sole discretion, file a claim
for refund arising from such Carryback and pay such refund to TODCO in
accordance with Section 5.

               (b) Adjustment of Tax Items. In the event that a Carryback by the
TODCO Tax Group to a Consolidated Year or Combined Year increases the liability
for Taxes of the Transocean Tax Group, the amount of the refund to which the
TODCO Tax Group shall be entitled to receive, in accordance with Section 5,
shall be net of such increased liability to the Transocean Tax Group.

                                      -16-
<PAGE>

         4.4 Tax Benefits Resulting from Exercise of Employee Stock Options. If
(x) pursuant to the exercise of an employee stock option the Transocean Tax
Group delivers to an employee of the TODCO Tax Group stock of Transocean at any
time during a Tax Year, or portion thereof, that begins after the IPO Closing
Date and (y) the delivery of such stock results in a present or potential future
Tax Benefit to the TODCO Tax Group, TODCO shall pay to Holdings the deemed value
of such Tax Benefit within thirty days after the delivery of such stock. For
purposes of this Section 4.4, the deemed value of such Tax Benefit shall be an
amount equal to the product of (x) the amount of the deduction allowed to the
TODCO Tax Group by the Code with respect to the delivery of the Transocean stock
and (y) the highest statutory rate applicable under Section 11 of the Code.
However, if any deduction otherwise described in this Section 4.4 exceeds
U.S.$1.0 million, determined on an employee-by-employee basis, the Tax Benefit
relating to such deduction shall not be treated as a Tax Benefit described in
this Section 4.4, but the underlying deduction shall be treated in the same
manner as if it were a Tax Asset created on or before the IPO Closing Date, as
described in Section 4.2.

         SECTION 5. TAX PAYMENTS AND INTERCOMPANY BILLINGS.

         5.1 Consolidated and Combined Returns.

               (a) Computation and Payment of Tax Due. At least ten business
days prior to any Payment Date for a Consolidated or Combined Return, Holdings
shall compute the amount of Tax required to be paid to the relevant Tax
Authority with respect to such Tax Return on such Payment Date and shall notify
TODCO in writing of (x) the amount of Tax required to be paid on such Payment
Date, and (y) the amount, if any, of such Tax which is allocable to TODCO under
Sections 2.1(a), 2.2(a) and 2.3(a). Holdings will pay, or shall cause one or
more of its Subsidiaries (other than members of the TODCO Tax Group) to pay, the
amount described in clause (x) of the immediately preceding sentence to the
relevant Tax Authority on or before such Payment Date.

               (b) Computation and Payment of TODCO Liability With Respect to
Tax Due. Within thirty days following any Payment Date, TODCO will pay to
Holdings (or another member of the Transocean Tax Group designated by Holdings
pursuant to Section 5.5) the amount, if any, of Tax paid on such Payment Date
for which TODCO is liable in accordance with Sections 2.1(a), 2.2(a) and 2.3(a),
appropriately adjusted for prior payments made by TODCO with respect to that
Consolidated or Combined Year. If, at any time, the total amount of payments
made by TODCO to Transocean (or any of its Subsidiaries other than members of
the TODCO Tax Group) with respect to Taxes for a Combined Year exceeds the
amount for which TODCO is liable in accordance with Sections 2.1(a), 2.2(a) and
2.3(a), Holdings will promptly remit the excess to TODCO.

         5.2 Payment of Refunds and Tax Benefits. Except as otherwise provided
in this Agreement:

                                      -17-
<PAGE>

               (a) Refund or Tax Benefit Received by Transocean Tax Group. If a
member of the Transocean Tax Group receives a Tax refund with respect to Taxes
for which a member of the TODCO Tax Group is liable hereunder or receives a Tax
Benefit for which TODCO is entitled to reimbursement hereunder, Holdings, as
appropriate, shall pay to TODCO, within thirty days following the receipt of the
Tax refund or Tax Benefit, an amount equal to such Tax refund or Tax Benefit.
Unless specified otherwise in this Agreement, a Tax Benefit will be considered
received at the time the Tax Return is filed with respect to such Tax Benefit.

               (b) Refund or Tax Benefit Received or Tax Asset Used by TODCO Tax
Group. If a member of the TODCO Tax Group receives a Tax refund with respect to
Taxes for which a member of the Transocean Tax Group is liable hereunder,
receives a Tax Benefit for which Holdings is entitled to reimbursement
hereunder, or uses or absorbs a Tax Asset for which Holdings is entitled to
reimbursement, TODCO shall pay to Holdings, within thirty days after the receipt
of the Tax refund or Tax Benefit or use or absorption of the Tax Asset, an
amount equal to such Tax refund or Tax Benefit. Unless specified otherwise in
this Agreement, a Tax Benefit will be considered received, and a Tax Asset will
be considered used or absorbed, at the time the Tax Return is filed with respect
to such Tax Benefit or Tax Asset.

         5.3 Initial Determinations and Subsequent Adjustments.

               (a) General Rules. The initial determination of the amount of a
payment, if any, which one Company is required to make to another under this
Agreement shall be made on the basis of the Tax Return as filed, or, if the Tax
to which the payment relates is not reported in a Tax Return, on the basis of
the amount of Tax initially paid to the Tax Authority. Except as otherwise
provided in Section 8.3, payments will be made, as appropriate, if additional
Taxes to which such determination relates are subsequently paid, or a refund of
such Taxes or a Tax Benefit relating to such Taxes is received, whether as a
result of an audit by a Tax Authority or for any other reason. Each payment
required by the immediately preceding sentence (x) as a result of a payment of
additional Taxes will be due thirty days after the date on which the additional
Taxes were paid or, if later, thirty days after the date of a request from the
other Company for the payment or (y) as a result of the receipt of a refund or
Tax Benefit will be due thirty days after the refund or Tax Benefit was
received. If a payment is made as a result of an audit by a Tax Authority which
does not conclude the matter, further adjusting payments will be made, as
appropriate, to reflect the outcome of subsequent administrative or judicial
proceedings.

               (b) Taxes that Generate TODCO Tax Benefits. If (x) pursuant to
Section 5.3(a), Holdings indemnifies TODCO and its Subsidiaries against any
additional State Income Tax, Foreign Income Tax, or Other Tax that is
attributable to any Tax Year or portion thereof beginning before the IPO Closing
Date and (y) the payment of such Tax generates a present or potential future Tax
Benefit to the TODCO Tax Group, then TODCO shall be liable for and pay to
Holdings within thirty days after the payment of such Tax by Holdings the deemed
value of such Tax Benefit. For purposes of this Section 5.3(b), the deemed value
of such Tax Benefit shall be an amount equal to the

                                      -18-
<PAGE>

product of (x) the amount of the Tax giving rise to such Tax Benefit and (y) the
highest statutory rate applicable under Section 11 of the Code. However, if any
Tax otherwise described in this Section 5.3(b) exceeds U.S.$1.0 million,
determined separately for each Tax Contest, the Tax Benefit relating to such Tax
shall not be treated as a Tax Benefit described in this Section 5.3(b), but the
underlying deduction allowed by the Code arising from the payment of such Tax
shall be treated in the same manner as if it were a Tax Asset created on or
before the IPO Closing Date, as described in Section 4.2.

         5.4 Indemnification Payments. Except as otherwise provided in Section
2.5(d), if any member of one Group is required to make a payment to a Tax
Authority for Taxes for which a Company belonging to the other Group is liable
under this Agreement, the Company which is liable for such Taxes under this
Agreement will remit the amount for which it is liable to the appropriate other
Company within thirty days after receiving notification requesting such amount.

         5.5 Payments by or to Other Members of the Groups. When appropriate
under the circumstances to reflect the underlying liability for a Tax or
entitlement to a Tax refund or Tax Benefit, a payment which is required to be
made by or to a Company may be made by or to another member of the Group to
which that Company belongs, but nothing in this Section 5.5 shall relieve any
Company of its obligations under this Agreement.

         5.6 Interest. Payments pursuant to this Agreement that are not made
within the period prescribed in this Agreement or, if no period is prescribed,
within fifteen (15) business days after demand for payment is made (the "Payment
Period") shall bear interest for the period from and including the date
immediately following the last date of the Payment Period through and including
the date of payment at a per annum rate equal to the rate specified in Section
6.5 of the Master Separation Agreement.. Such interest will be payable at the
same time as the payment to which it relates and shall be calculated on the
basis of a year of 365 days and the actual number of days for which due.

         5.7 Tax Consequences of Payments. For all Tax purposes and to the
extent permitted by applicable law, the parties hereto shall treat any payment
made pursuant to this Agreement as a capital contribution or a dividend
distribution, as the case may be, immediately prior to the Effective Date and,
accordingly, as not includible in the taxable income of the recipient. If a Tax
Authority determines that the receipt or accrual of any payment made under this
Agreement is taxable to the payee, the payer shall pay to the payee an amount
equal to any increase in the Income Taxes of the payee as a result of receiving
the payment (grossed up to take into account such payment, if applicable).

         SECTION 6. ASSISTANCE AND COOPERATION. The parties will cooperate (and
cause their respective affiliates to cooperate) with each other and with each
other's agents, including accounting firms and legal counsel, in connection with
Tax matters, including provision of relevant documents and information in their
possession and making available to each other, as reasonably requested and
available, personnel (including officers, directors, employees and agents of the
Companies or their affiliates)

                                      -19-
<PAGE>

responsible for preparing, maintaining, and interpreting information and
documents relevant to Taxes, and personnel reasonably required as witnesses or
for purposes of providing information or documents in connection with any
administrative or judicial proceedings relating to Taxes. Any information or
documents provided under this Section 6 shall be kept confidential by the
Company receiving the information or documents, except as may otherwise be
necessary in connection with the filing of Tax Returns or in connection with any
administrative or judicial proceedings relating to Taxes.

         SECTION 7. TAX RECORDS.

         7.1 Retention of Tax Records. Each Company shall preserve, and shall
cause its affiliates to preserve, all Tax Records which are in its possession,
and which could affect the liability of any member of the other Group for Taxes,
for so long as the contents thereof may become material in the administration of
any matter under applicable Tax Law, but in any event until the later of (x) the
expiration of any applicable statutes of limitation, as extended, and (y) seven
years after the IPO Closing Date.

         7.2 Access to Tax Records. The Companies and their respective
affiliates shall make available to members of the other Group for inspection and
copying during normal business hours upon reasonable notice all Tax Records in
their possession to the extent reasonably requested by any such member of the
other Group in connection with the preparation of Tax Returns, audits,
litigation, or the resolution of items under this Agreement.

         SECTION 8. TAX CONTESTS.

         8.1 Notices. Each of the parties shall provide prompt notice to the
other party of any pending or threatened Tax audit, assessment or proceeding or
other Tax Contest of which it becomes aware relating to Taxes for which it is or
may be indemnified by the other party hereunder. Such notice shall contain
factual information (to the extent known) describing any asserted Tax liability
in reasonable detail and shall be accompanied by copies of any notice and other
documents received from any Tax Authority in respect of any such matters. If an
indemnified party has knowledge of an asserted Tax liability with respect to a
matter for which it is to be indemnified hereunder and such party fails to give
the indemnifying party prompt notice of such asserted Tax liability, then (x) if
the indemnifying party is precluded from contesting the asserted Tax liability
in any forum as a result of the failure to give prompt notice, the indemnifying
party shall have no obligation to indemnify the indemnified party for any Taxes
arising out of such asserted Tax liability, and (y) if the indemnifying party is
not precluded from contesting the asserted Tax liability in any forum, but such
failure to give prompt notice results in a monetary detriment to the
indemnifying party, then any amount which the indemnifying party is otherwise
required to pay the indemnified party pursuant to this Agreement shall be
reduced by the amount of such detriment.

         8.2 Control of Tax Contests. Each Company shall have full
responsibility and discretion in handling, settling or contesting any Tax
Contest involving a Tax for which it is liable pursuant to Section 2 of this
Agreement, except that (x)

Holdings shall have full responsibility and discretion in handling, settling or
contesting any Tax Contest with respect to a Consolidated Return or Combined
Return and (y) TODCO shall not, without written consent from Holdings, exercise
its discretion in handling, settling or contesting or paying Taxes subject to
any Tax Contest in a manner that TODCO knows, or reasonably should know, would
adversely affect any member of the Transocean Tax Group.

         8.3 Cooperation. The indemnified Company shall provide the Company
controlling any Tax Contest pursuant to Section 8.2 with all information
relating to the indemnified Company and its Subsidiaries which the Company
controlling the Tax Contest needs to handle, settle or contest the Tax Contest.
At the request of the Company controlling the Tax Contest, the indemnified
Company shall take any action (e.g., executing a power of attorney) that is
reasonably necessary in order for the Company controlling the Tax Contest to
handle, settle or contest the Tax Contest. TODCO shall assist Holdings in taking
any remedial actions permitted by Internal Revenue Service Revenue Procedure
99-32 in order to avoid the effects of any secondary adjustment under Section
482 of the Code. The Company controlling the Tax Contest shall have no
obligation to indemnify the indemnified Company for any additional Taxes
resulting from the Tax Contest, if the indemnified Company fails to cooperate
fully or provide complete assistance to the Company controlling the Tax Contest.

         SECTION 9. RESTRICTION ON CERTAIN POST-IPO ACTIONS OF TODCO. TODCO
agrees that it will not take or fail to take, or permit any Subsidiary of TODCO
to take or fail to take, any action where such action or failure to act would be
inconsistent with or prohibit a distribution by Transocean of its stock in TODCO
from qualifying as a tax-free distribution under Section 355 of the Code.
