defined in Section 1.1 and the definitions of the other capitalized terms used in this
Agreement are cross-referenced in Section 1.2.

W I T N E S S E T H:

     WHEREAS, the board of directors of Helix has determined that it is appropriate and desirable
for Helix to separate the Cal Dive Group from Helix;

     WHEREAS, in connection with the separation of the Cal Dive Group from Helix, Helix desires to

assign or otherwise transfer, to Cal Dive and certain of Cal Dive’s Subsidiaries, certain Assets
and Liabilities associated with the Cal Dive Business;

     WHEREAS, Helix has entered into a Credit Agreement with                     , as Agent and the various

to Helix (the “Transfer Credit Facility”);

     WHEREAS, as of the date hereof, Helix has drawn the principal amount of USD $                     under
the Transfer Credit Facility;

     WHEREAS, Helix has agreed to transfer certain vessels constituting part of the Cal Dive Assets
(as defined below) to CDI Vessel Holdings LLC, a Delaware limited liability company (“Vessel

membership interests;

WHEREAS, Helix owns 100% of the issued and outstanding stock of Holdings;

     WHEREAS, in connection with the transfer of the vessels to Vessel Holdings, Vessel Holdings

     WHEREAS, Cal Dive has agreed to guaranty the indebtedness of Vessel Holdings under the

     WHEREAS, immediately following the consummation of the Initial Public Offering, Helix will own
approximately ___shares of Cal Dive Common Stock;

     WHEREAS, it is appropriate and desirable to set forth the principal corporate transactions
required to effect the Separation and certain other agreements that will, following the
consummation of the Initial Public Offering, govern certain matters relating to the Separation, the

     WHEREAS, the terms and conditions set forth herein have not resulted from arms length

–subsidiary relationship, and accordingly, such terms and conditions may be in some respects less
favorable to Cal Dive than those it could obtain from unaffiliated third parties.

THE SEPARATION

     2.1 Transfer of Cal Dive Assets; Assumption of Cal Dive Liabilities.

     (a) The Separation shall be effected in accordance with the terms and conditions of this
Agreement and the other Transfer Documents. Subject to Section 3.7, immediately following
the execution and delivery of the Underwriting Agreement by each of the parties thereto:

     (i) Helix shall, and shall cause its applicable Subsidiaries to, contribute, assign,
transfer, convey and deliver to Cal Dive or certain of Cal Dive’s Subsidiaries designated by
Cal Dive, and Cal Dive or such applicable Subsidiaries shall accept from Helix and its
applicable Subsidiaries, all of Helix’s and such Subsidiaries’ respective rights, titles and
interests in and to all Cal Dive Assets, with such contributions, assignments, transfers and
conveyances being subject to the terms and conditions of this Agreement and any applicable
Transfer Documents; and

     (ii) Cal Dive shall, and shall cause its domestic Subsidiaries to, accept, assume and
agree, on a several and not joint basis, to perform, discharge and fulfill all the Cal Dive
Liabilities, in accordance with their respective terms. Cal Dive and such Subsidiaries
shall be responsible for all Cal Dive Liabilities assumed by it, regardless of when or where
such Cal Dive Liabilities arose or arise, or whether the facts on which they are based
occurred prior to or subsequent to the Closing Date, regardless of where or against whom
such Cal Dive Liabilities are asserted or determined (including any Cal Dive Liabilities
arising out of claims made by Helix’s or Cal Dive’s respective directors, officers,
employees, agents, Subsidiaries or Affiliates against any member of the Helix Group or the
Cal Dive Group) or whether asserted or determined prior to the date hereof, and, except as
set forth in Section 2.3(b)(iii), regardless of whether arising from or alleged to
arise from negligence, recklessness, violation of Law, fraud or misrepresentation by any
member of the Helix Group or the Cal Dive Group, or any of their past or present respective
directors, officers, employees, agents, Subsidiaries or Affiliates. Such assumption of Cal
Dive Liabilities shall be subject to the terms and conditions of this Agreement and any
applicable Transfer Documents.

     (b) Each of the parties agrees that Delayed Transfer Assets, if any, will be contributed,
assigned, transferred, conveyed and delivered, and Delayed Transfer Liabilities, if any, will be
accepted and assumed, in accordance with the terms of the applicable Transaction Documents.
Notwithstanding the date on which any such Delayed Transfer Asset is actually contributed,
assigned, conveyed and delivered, or the date on which any such Delayed Transfer Liability is
actually accepted and assumed, such contribution, assignment, transfer, conveyance and delivery of
any Delayed Transfer Asset, or the acceptance and assumption of any Delayed Transfer Liability,
shall be deemed to have taken place on, and shall be effective as of, the Closing Date, and the
applicable Delayed Transfer Asset or Delayed Transfer Liability shall be treated for all purposes
of this Agreement and the Transaction Documents as a Cal Dive Asset or a Cal Dive Liability, as the
case may be, from and after the Closing Date.

-10-

 

     (c) If at any time or from time to time (whether prior to or after the Closing Date) any party
hereto (or any member of such party’s respective Group) shall receive or otherwise possess any
Asset that is allocated to any other Person pursuant to this Agreement or any Transaction Document,
such party shall promptly transfer, or cause to be transferred, such Asset to the Person so
entitled thereto. This Section 2.2(c) shall not apply to any Assets acquired by Helix or Cal Dive
more than one hundred eighty (180) days following the Closing Date.

     (d) Cal Dive hereby waives compliance by each member of the Helix Group with the requirements
and provisions of the “bulk-sale” or “bulk-transfer” Laws of any jurisdiction that may otherwise be
applicable with respect to the transfer or sale of any or all of the Cal Dive Assets to any member
of the Cal Dive Group.

     2.2 Cal Dive Assets.

     (a) Subject to Section 2.2(b), for purposes of this Agreement, “Cal Dive
Assets” shall mean (without duplication):

     (i) all Assets that are expressly provided by this Agreement or any Transaction
Document as Assets to be transferred by Helix and other members of the Helix Group to Cal
Dive or another designated member of the Cal Dive Group;

     (ii) all Cal Dive Contracts;

     (iii) the stock and limited liability company membership interests listed on
Schedule 2.2 hereto of the corporations and limited liability companies described on
Schedule 2.2 (the “Transferred Subsidiaries”);

     (iv) subject to Section 6.3, any rights of any member of the Cal Dive Group
under any of the Insurance Policies, including any rights thereunder arising after the
Closing Date in respect of any Insurance Policies;

     (v) all Assets reflected as Assets of Cal Dive and its Subsidiaries in the Cal Dive
Balance Sheet, other than any dispositions of such Assets subsequent to the date of the Cal
Dive Balance Sheet; and

     (vi) any and all Assets owned or held immediately prior to the Closing Date by Helix or
any of its Subsidiaries that are used exclusively in the Cal Dive Business. The intention
of this clause (i) is only to rectify any inadvertent omission of transfer or
conveyance of any Asset that, had the parties given specific consideration to such Asset as
of the date hereof, would have otherwise been classified as a Cal Dive Asset.

     (b) Notwithstanding the foregoing, the Cal Dive Assets shall not in any event include the
Excluded Assets. For purposes of this Agreement, “Excluded Assets” shall mean Assets not
used exclusively in the Cal Dive Business, including, without limitation any and all Assets that
are expressly contemplated by this Agreement or any Transaction Document as either Assets to be
retained by Helix or any other member of the Helix Group, other than assets of the Transferred
Subsidiaries, or Assets that are to be transferred by Cal Dive or any member of the Cal Dive Group
to Helix or a designated member of the Helix Group.

-11-

 

     2.3 Cal Dive Liabilities.

     (a) Subject to Section 2.3(b), for purposes of this Agreement, “Cal Dive

     (i) all Liabilities that are expressly provided by this Agreement or any Transaction
Document as Liabilities to be assumed by Cal Dive or any other member of the Cal Dive Group,

and leasehold interests), in any such case whether arising before, on or after the
Closing Date; or

     (D) the ownership and operation of the Vessels.

     (iii) all Liabilities reflected as liabilities or obligations of Cal Dive or its
Subsidiaries in the Cal Dive Balance Sheet;

     (iv) all Liabilities related to Assumed Actions and Existing Actions, as further

without limitation, the obligations to repay the principal balance thereunder and accrued
interest thereon, fee and expenses of the lenders and the agent thereunder, and any
obligations to protect and indemnify the agent and the lenders thereunder, provided that Cal
Dive’s assumption thereof may take the form of a guaranty of such Transfer Credit Facility;

     (viii) all Liabilities arising out of claims made by Helix’s or Cal Dive’s respective
directors, officers, employees, agents, Subsidiaries or Affiliates against any member of the
Helix Group or the Cal Dive Group with respect to the Cal Dive Business;

     (viii) subject to Section 6.3, all Liabilities for insurance premiums and club
calls relating to the Cal Dive Assets or the Vessels; and

     (ix) Liabilities of the Transferred Subsidiaries.

     (b) Notwithstanding the foregoing, the Cal Dive Liabilities shall not in any event include the
Excluded Liabilities. For purposes of this Agreement, “Excluded Liabilities” shall mean
(without duplication):

     (i) any and all Liabilities that are expressly contemplated by this Agreement or any
Transaction Document as Liabilities to be retained or assumed by Helix or any other member
of the Helix Group, and all agreements and obligations of any member of the Helix Group
under this Agreement or any of the Transaction Documents;

     (ii) any and all Liabilities of a member of the Helix Group relating solely to, arising

Cal Dive Group).

     2.4 Termination of Agreements.

     (a) Except as set forth in Section 2.4(b), Cal Dive and each member of the Cal Dive
Group, on the one hand, and Helix and each member of the Helix Group, on the other hand, hereby
terminate any and all agreements, arrangements, commitments or understandings, whether or not in
writing, between or among Cal Dive or any member of the Cal Dive Group, on the one hand, and Helix
or any member of the Helix Group, on the other hand, effective as of the Closing Date. No such
terminated agreement, arrangement, commitment or understanding (including any provision thereof
which purports to survive termination) shall be of any further force or effect after the Closing
Date. Each party shall, at the reasonable request of any other party, take, or cause to be taken,
such other actions as may be necessary to effect the foregoing.

-13-

 

     (b) The provisions of Section 2.4(a) shall not apply to any of the following
agreements, arrangements, commitments or understandings (or to any of the provisions thereof):

     (i) this Agreement and the Transaction Documents (and each other agreement or
instrument expressly contemplated by this Agreement or any Transaction Document to be
entered into or continued by either of the parties or any of the members of their respective
Groups);

     (ii) except to the extent redundant with any provision of or service provided under
this Agreement or any of the Transaction Documents (including any exhibits or schedules
thereto), the agreements, arrangements, commitments and understandings listed or described
on Schedule 2.4(b)(ii);

     (iii) any agreements, arrangements, commitments or understandings to which any Person
other than the parties and their respective Affiliates is a party (it being understood that
to the extent that the rights and obligations of the parties and the members of their
respective Groups under any such agreements, arrangements, commitments or understandings
constitute Cal Dive Assets or Cal Dive Liabilities, they shall be assigned pursuant to
Section 2.1);

     (iv) any accounts or notes payable or accounts or notes receivable between a member of
the Helix Group, on the one hand, and a member of the Cal Dive Group, on the other hand,
accrued as of the Closing Date and reflected in the books and records of the parties or
otherwise documented in accordance with past practices;

     (v) any agreements, arrangements, commitments or understandings to which any non-wholly
owned Subsidiary of Helix or Cal Dive, as the case may be, is a party; and

     (vi) any other agreements, arrangements, commitments or understandings that this
Agreement or any Transaction Document expressly contemplates will survive the Closing Date.

     2.5 Governmental Approvals and Consents; Delayed Transfer Assets and Liabilities.

     (a) To the extent that the Separation requires any Governmental Approvals or Consents, the
parties will use their commercially reasonable efforts to obtain such Governmental Approvals and
Consents; provided, however, that neither Helix nor Cal Dive shall be obligated to contribute
capital in any form to any entity in order to obtain such Governmental Approvals and Consents.

     (b) If and to the extent that the valid, complete and perfected contribution, transfer or
assignment to the Cal Dive Group of any Cal Dive Assets or the assumption by the Cal Dive Group of
any Cal Dive Liabilities would be a violation of applicable Law or require any Consent or
Governmental Approval in connection with the Separation or the Initial Public Offering, then,
unless the parties mutually shall otherwise determine, the transfer or assignment to the Cal Dive
Group of such Cal Dive Assets or the assumption by the Cal Dive Group of such Cal Dive

-14-

 

Liabilities shall be automatically deemed deferred and any such purported contribution,
transfer, assignment or assumption shall be null and void until such time as all legal impediments
are removed or such Consents or Governmental Approvals have been obtained. If and when the
Consents and Governmental Approvals are obtained, the contribution, transfer or assignment of the
applicable Cal Dive Asset or Cal Dive Liability shall be effected in accordance with the terms of
this Agreement and/or the applicable Transfer Document. Any such Liability shall be deemed a
Delayed Transfer Liability. Any such Asset shall be deemed a Delayed Transfer Asset and
notwithstanding the foregoing, a Cal Dive Asset for purposes of determining whether any Liability
is a Cal Dive Liability.

     (c) If any contribution, transfer or assignment of any Cal Dive Asset intended to be
contributed, transferred or assigned hereunder or any assumption of any Cal Dive Liability intended
to be assumed by the Cal Dive Group hereunder is not consummated on the Closing Date for any
reason, then, insofar as reasonably possible, (i) the member of the Helix Group retaining such Cal
Dive Asset shall thereafter hold such Cal Dive Asset for the use and benefit of the member of the
Cal Dive Group entitled thereto (at the expense of the member of the Cal Dive Group entitled
thereto) and (ii) Cal Dive shall, or shall cause the applicable member of the Cal Dive Group to,
pay or reimburse the member of the Helix Group retaining such Cal Dive Liability for all amounts
paid or incurred in connection with such Cal Dive Liability. In addition, the member of the Helix
Group retaining such Cal Dive Asset shall, insofar as reasonably possible and to the extent
permitted by applicable Law, treat such Asset in the ordinary course of business in accordance
with past practice and take such other actions as may be reasonably requested by the Cal Dive Group
member to whom such Cal Dive Asset is to be transferred in order to place such Cal Dive Group
member in the same position as if such Cal Dive Asset had been transferred as contemplated hereby
and so that all the benefits and burdens relating to such Cal Dive Asset, including possession,
use, risk of loss, potential for gain, and dominion, control and command over such Cal Dive Asset,
is to inure from and after the Closing Date to the Cal Dive Group.

     (d) The Person retaining an Asset or Liability due to the deferral of the transfer of such
Asset or the deferral of the assumption of such Liability shall not be obligated, in connection
with the foregoing, to expend any money unless the necessary funds are advanced (or otherwise made
available) by the Person entitled to the Asset or the Person intended to be subject to the
Liability, other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar
fees, all of which shall be promptly reimbursed by the Person entitled to such Asset or the Person
intended to be subject to the Cal Dive Liability.

     2.6 Novation of Assumed Cal Dive Liabilities.

     (a) Each of Helix and Cal Dive, at the request of the other, shall use commercially reasonable
efforts to obtain, or to cause to be obtained, any Consent, substitution or amendment required to
novate or assign all obligations under agreements, leases, licenses and other obligations or
Liabilities of any nature whatsoever that constitute Cal Dive Liabilities, or to obtain in writing
the unconditional release of all parties to such arrangements (other than any member of the Cal
Dive Group), so that, in any such case, Cal Dive and the other members of the Cal Dive Group will
be solely responsible for such Cal Dive Liabilities; provided, however, that
neither the Helix Group nor the Cal Dive Group shall be obligated to pay any consideration or

-15-

 

assume any additional obligation therefor to any third party from whom any such Consent,
substitution or amendment is requested.

     (b) If Helix or Cal Dive is unable to obtain, or to cause to be obtained, any such required
Consent, release, substitution or amendment, the applicable member of the Helix Group shall
continue to be bound by such agreement, lease, license or other obligation that constitutes a Cal
Dive Liability and, unless not permitted by Law or the terms thereof, as agent or subcontractor for
such member of the Helix Group, Cal Dive shall, or shall cause a member of the Cal Dive Group to,
pay, perform and discharge fully all the obligations or other Liabilities of members of the Helix
Group thereunder that constitute Cal Dive Liabilities from and after the Closing Date. Cal Dive
shall indemnify each Helix Indemnified Party, and hold each of them harmless against any
Liabilities arising in connection therewith; provided that, Cal Dive shall have no
obligation to indemnify any Helix Indemnified Party with respect to any matter to the extent that
such Helix Indemnified Party has engaged in any knowing violation of Law, fraud or
misrepresentation in connection therewith. Helix shall, without further consideration, promptly
pay and remit, or cause to be promptly paid or remitted, to Cal Dive, all money, rights and other
consideration received by it or any member of the Helix Group in respect of such performance
(unless any such consideration is an Excluded Asset). If and when any such Consent, release,
substitution or amendment shall be obtained or such agreement, lease, license or other rights or
obligations shall otherwise become assignable or able to be novated, Helix shall thereafter assign,
or cause to be assigned, all rights and obligations of any member of the Helix Group thereunder and
any other Cal Dive Liabilities thereunder to Cal Dive or a designated member of the Cal Dive Group,
without payment of further consideration and Cal Dive, or a designated member of the Cal Dive
Group, shall, without the payment of any further consideration, assume such Cal Dive Liabilities
and rights.

     2.7 Novation of Liabilities other than Cal Dive Liabilities.

     (a) Each of Helix and Cal Dive, at the request of the other, shall use commercially reasonable
efforts to obtain, or to cause to be obtained, any Consent, substitution, or amendment required to
novate or assign all obligations under agreements, leases, licenses and other obligations or
Liabilities for which a member of the Helix Group and a member of the Cal Dive Group are jointly or
severally liable and that do not constitute Cal Dive Liabilities, or to obtain in writing the
unconditional release of all parties to such arrangements other than any member of the Helix Group,
so that, in any such case, the members of the Helix Group will be solely responsible for such
Liabilities; provided, however, that neither the Helix Group nor the Cal Dive Group
shall be obligated to pay any consideration therefor to any third party from whom any such Consent,
substitution or amendment is requested.

     (b) If Helix or Cal Dive is unable to obtain, or to cause to be obtained, any such required
Consent, release, substitution or amendment, the applicable member of the Cal Dive Group shall
continue to be bound by such agreement, lease, license or other obligation that does not constitute
a Cal Dive Liability and, unless not permitted by Law or the terms thereof, as agent or
subcontractor for such member of the Cal Dive Group, Helix shall, or shall cause a member of the
Helix Group to, pay, perform and discharge fully all the obligations or other Liabilities of such
member of the Cal Dive Group thereunder from and after the Closing Date. Helix shall indemnify
each Cal Dive Indemnified Party and hold each of them harmless against

-16-

 

any Liabilities (other than Cal Dive Liabilities) arising in connection therewith;
provided that, Helix shall have no obligation to indemnify any Cal Dive Indemnified
Party with respect to any matter to the extent that such Cal Dive Indemnified Party has engaged in
any knowing violation of Law, fraud or misrepresentation in connection therewith. Cal Dive shall,
without further consideration, promptly pay and remit, or cause to be promptly paid or remitted, to
Helix or to another member of the Helix Group specified by Helix, all money, rights and other
consideration received by it or any member of the Cal Dive Group in respect of such performance
(unless any such consideration is a Cal Dive Asset). If and when any such Consent, release,
substitution or amendment shall be obtained or such agreement, lease, license or other rights or
obligations shall otherwise become assignable or able to be novated, Cal Dive shall promptly
assign, or cause to be assigned, all rights, obligations and other Liabilities thereunder of any
member of the Cal Dive Group to Helix or to another member of the Helix Group specified by Helix,
without payment of any further consideration and Helix, or another member of the Helix Group,
without the payment of any further consideration shall assume such rights and Liabilities.

     2.8 Transfers of Assets and Assumption of Liabilities.

     In furtherance of the contribution, assignment, transfer and conveyance of Cal Dive Assets and
the assumption of Cal Dive Liabilities, on the Closing Date, (a) Helix shall execute and deliver,
and shall cause the other members of the Helix Group to execute and deliver, such stock powers,
merger certificates, bills of sale, certificates of title, assignments of contracts and other
instruments of contribution, transfer, conveyance and assignment as and to the extent necessary to
evidence the contribution, transfer, merger, conveyance and assignment of all of the Helix Group’s
right, title and interest in and to the Cal Dive Assets to the Cal Dive Group, and (b) Cal Dive
shall execute and deliver, and shall cause the other members of the Cal Dive Group to execute and
deliver, such assumptions of contracts and other instruments of assumption as and to the extent
necessary to evidence the valid and effective assumption of the Cal Dive Liabilities by the Cal
Dive Group. All of the foregoing documents contemplated by this Section 2.8 shall be
referred to collectively herein as the “Helix Transfer Documents.”

     2.9 Transfer of Excluded Assets by Cal Dive; Assumption of Excluded Liabilities by
Helix.

     (a) To the extent any Excluded Asset or Excluded Liability is transferred to a member of the
Cal Dive Group at the Closing or remains owned or held by a member of the Cal Dive Group after the
Closing, from and after the Closing:

     (i) Cal Dive shall, and shall cause the members of the Cal Dive Group to, promptly
contribute, assign, transfer, convey and deliver to Helix or designated Helix Group members,
and Helix or such Helix Group members shall accept from Cal Dive and its applicable Group
members, all of Cal Dive’s and such Group members’ respective rights, titles and interests
in and to such Excluded Assets.

     (ii) Helix and certain Helix Group members designated by Helix, shall promptly accept,
assume and agree to perform, discharge and fulfill all such Excluded Liabilities in
accordance with their respective terms.

-17-

 

     (iii) In furtherance of the assignment, transfer and conveyance of Excluded Assets and
the assumption of Excluded Liabilities (A) Cal Dive shall execute and deliver, and shall
cause its Subsidiaries to execute and deliver, such bills of sale, stock powers,
certificates of title, assignments of contracts and other instruments of transfer,
conveyance and assignment as and to the extent necessary to evidence the transfer,
conveyance and assignment of all of Cal Dive’s and its Subsidiaries’ right, title and
interest in and to the Excluded Assets to Helix and its Subsidiaries, and (B) Helix shall
execute and deliver such assumptions of contracts and other instruments of assumption as and
to the extent necessary to evidence the valid and effective assumption of the Excluded
Liabilities by Helix. All of the foregoing documents contemplated by this Section
2.9(a)(iii) shall be referred to collectively herein as the “Cal Dive Transfer
Documents” and, together with the Helix Transfer Documents, the “Transfer
Documents.”

     (iv) To the extent that the transfer of such Excluded Assets and the assumption of such
Excluded Liabilities requires any Governmental Approvals or Consents, the parties shall use
commercially reasonable efforts to obtain such Governmental Approvals and Consents;
provided, however, that neither Helix nor Cal Dive shall be obligated to
contribute capital in any form to any entity in order to obtain such Governmental Approvals
and Consents.

     (v) If and to the extent that the valid, complete and perfected transfer or assignment
to the Helix Group of any Excluded Assets or the assumption by the Helix Group of any
Excluded Liabilities would be a violation of applicable Law or require any Consent or
Governmental Approval, then, unless the parties mutually shall otherwise determine, the
transfer or assignment to the Helix Group of such Excluded Assets or the assumption by the
Helix Group of such Excluded Liabilities shall be automatically deemed deferred and any such
purported transfer, assignment or assumption shall be null and void until such time as all
legal impediments are removed or such Consents or Governmental Approvals have been obtained.

     (b) If any transfer or assignment of any Excluded Asset intended to be transferred or assigned
hereunder or any assumption of any Excluded Liability intended to be assumed by Helix hereunder is
not consummated on the Closing Date, whether as a result of the failure to obtain any required
Governmental Approvals or Consents or any other reason, then, insofar as reasonably possible, (i)
the member of the Cal Dive Group retaining such Excluded Asset shall thereafter hold such Excluded
Asset for the use and benefit of Helix (at Helix’s expense) and (ii) Helix shall, or shall cause
its applicable Group member to, pay or reimburse the member of the Cal Dive Group retaining such
Excluded Liability for all amounts paid or incurred in connection with such Excluded Liability. In
addition, the member of the Cal Dive Group retaining such Excluded Asset shall, insofar as
reasonably possible and to the extent permitted by applicable Law, treat such Excluded Asset in the
ordinary course of business in accordance with past practice and take such other actions as may be
reasonably requested by Helix in order to place Helix in the same position as if such Excluded
Asset had been transferred as contemplated hereby and so that all the benefits and burdens relating
to such Excluded Asset, including possession, use, risk of loss, potential for gain, and dominion,
control and command over such Excluded Asset, is to inure from and after the Closing Date to the
Helix Group.

-18-

 

     (c) If and when the Consents and Governmental Approvals, the absence of which caused the
deferral of transfer of any Excluded Asset or the deferral of assumption of any Excluded Liability,
are obtained, the transfer or assignment of the applicable Excluded Asset or Excluded Liability
shall be effected in accordance with the terms of this Agreement and/or the applicable Transfer
Document.

     (d) Any member of the Cal Dive Group retaining an Excluded Asset or Excluded Liability due to
the deferral of the transfer of such Excluded Asset or the deferral of the assumption of such
Excluded Liability shall not be obligated, in connection with the foregoing, to expend any money
unless the necessary funds are advanced (or otherwise made available) by Helix or the member of the
Helix Group intended to be subject to the Excluded Liability, other than reasonable out-of-pocket
expenses, attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed
by Helix or the member of the Helix Group entitled to such Excluded Asset or intended to be subject

ECONOMIC AND LEGAL RISKS THAT (I) ANY CONVEYANCE SHALL PROVE TO BE INSUFFICIENT TO VEST IN THE

will include the certifications in Cal Dive’s periodic reports, as and when required pursuant to
Exchange Act Rule 13a-14 and Item 601 of Regulation S-K; Cal Dive will cause its management to
evaluate Cal Dive’s disclosure controls and procedures and internal control over financial
reporting (including any change in internal control over financial reporting) as and when required
pursuant to Exchange Act Rule 13a-15; Cal Dive will disclose in its periodic reports filed with the
SEC information concerning Cal Dive management’s responsibilities for and evaluation of Cal Dive’s

auditors relating to internal control over financial reporting) as and when required under Items
307 and 308 of Regulation S-K and other applicable SEC rules; and, without limiting the general
application of the foregoing, Cal Dive will, and will cause each other member of the Cal Dive Group
to, maintain as of and after the Closing Date internal systems and procedures that will provide

accordance with GAAP and applicable law, (B) all transactions of members of the Cal Dive Group are
recorded as necessary to permit the preparation of the Financial Statements, (C) the receipts and
expenditures of members of the Cal Dive Group are authorized at the appropriate level within Cal
Dive, and (D) unauthorized use or disposition of the assets of any member of the Cal Dive Group
that could have material effect on the financial statements of the Cal Dive Group is prevented or
detected in a timely manner.

     (ii) Fiscal Year. Cal Dive will, and will cause each member of the Cal Dive Group
organized in the United States to, maintain a fiscal year that commences and ends on the same
calendar day as Helix’s fiscal year commences and ends, and to maintain monthly accounting periods
that commence and end on the same calendar days as Helix’s monthly accounting periods commence and
end.

     (iii) Monthly Financial Reports. No later than five (5) Business Days after the end
of each monthly accounting period of Cal Dive following the Closing Date (including the last
monthly accounting period of Cal Dive of each fiscal year), Cal Dive will deliver to Helix a
consolidated income statement, balance sheet and statement of cash flow for Cal Dive for such
period and an income statement, balance sheet and statement of cash flow for each Cal Dive
Affiliate that is consolidated with Cal Dive, as the case may be, in such format and detail as
Helix may request.

     (iv) Quarterly Financial Statements. As soon as practicable, and in any event no

SEC for each of the first three (3) fiscal quarters in each fiscal year of Cal Dive, and (y) five
(5) Business Days prior to the date on which Helix has notified

-22-

 

Cal Dive that Helix intends to file its Form 10-Q or other document containing quarterly
financial statements with the SEC, Cal Dive will deliver to Helix drafts of (A) the consolidated
financial statements of the Cal Dive Group (and notes thereto) for such periods and for the period
from the beginning of the current fiscal year to the end of such quarter, setting forth in each
case in comparative form for each such fiscal quarter of Cal Dive the consolidated figures (and
notes thereto) for the corresponding quarter and periods of the previous fiscal year and all in
reasonable detail and prepared in accordance with Article 10 of Regulation S-X and GAAP, and (B) a
discussion and analysis by Cal Dive’s management of the Cal Dive Group’s financial condition and
results of operations for such fiscal period, including, without limitation, an explanation of any
material period-to-period change and any off-balance sheet transactions, all in reasonable detail
and prepared in accordance with Item 303(b) of Regulation S-K; provided, however,
that Cal Dive will deliver such information at such earlier time upon Helix’s written request with
thirty (30) days’ notice resulting from Helix’s determination to accelerate the timing of the
filing of its financial statements with the SEC. The information set forth in clauses (A)
and (B) above is referred to in this Agreement as the “Quarterly Financial
Statements.” No later than the earlier of (1) three (3) Business Days prior to the date Cal
Dive publicly files the Quarterly Financial Statements with the SEC or otherwise makes such
Quarterly Financial Statements publicly available, and (2) three (3) Business Days prior to the
date on which Helix has notified Cal Dive that Helix intends to file its quarterly financial
statements with the SEC, Cal Dive will deliver to Helix the final form of the Quarterly Financial
Statements and certifications thereof by the principal executive and financial officers of Cal Dive
in the forms required under SEC rules for periodic reports; provided, however, that
Cal Dive may continue to revise such Quarterly Financial Statements prior to the filing thereof in
order to make corrections and non-substantive changes which corrections and changes will be
delivered by Cal Dive to Helix as soon as practicable, and in any event within eight (8) hours
thereafter; provided, further, that Helix’s and Cal Dive’s financial
Representatives will actively consult with each other regarding any changes (whether or not
substantive) that Cal Dive may consider making to the Quarterly Financial Statements and related
disclosures during the two (2) Business Days immediately prior to any anticipated filing with the
SEC, with particular focus on any changes which would have an effect upon Helix’s financial
statements or related disclosures. In addition to the foregoing, no Quarterly Financial Statement
or any other document which refers to, or contains information not previously publicly disclosed
with respect to, Helix’s ownership interest in Cal Dive or the Separation will be filed with the
SEC or otherwise made public by any Cal Dive Group member without the prior written consent of
Helix. Notwithstanding anything to the contrary in this Section 4.1(a)(iv), Cal Dive will
file the Quarterly Financial Statements with the SEC on the same date and at substantially the same
time that Helix files its quarterly financial statements with the SEC unless otherwise required by
applicable law.

     (v) Annual Financial Statements. As soon as practicable, and in any event no later
than the earlier of (x) ten (10) Business Days prior to the date on which Cal Dive is required to
file a Form 10-K or other document containing its Annual Financial Statements with the SEC, and (y)
ten (10) Business Days prior to the date on which Helix has notified Cal Dive that Helix intends to
file its Form 10-K or other document containing annual financial statements with the SEC, Cal Dive
will deliver to Helix (A)

-23-

 

drafts of the consolidated financial statements of the Cal Dive Group (and notes thereto) for
such year, setting forth in each case in comparative form the consolidated figures (and notes
thereto) for the previous fiscal year and all in reasonable detail and prepared in accordance with
Regulation S-X and GAAP, and (B) a discussion and analysis by Cal Dive’s management of the Cal Dive
Group’s financial condition and results of operations for such year, including, without limitation,
an explanation of any material period-to-period change and any off-balance sheet transactions, all
in reasonable detail and prepared in accordance with Item 303(a) of Regulation S-K. The information
set forth in clauses (A) and (B) above is referred to in this Agreement as the
“Annual Financial Statements.” Cal Dive will deliver to Helix all revisions to such drafts
as soon as any such revisions are prepared or made. No later than the earlier of (1) five (5)
Business Days prior to the date Cal Dive publicly files the Annual Financial Statements with the
SEC or otherwise makes such Annual Financial Statements publicly available, and (2) five (5)
Business Days prior to the date on which Helix has notified Cal Dive that Helix intends to file its
annual financial statements with the SEC, Cal Dive will deliver to Helix the final form of the Cal
Dive Annual Financial Statements and certifications thereof by the principal executive and
financial officers of Cal Dive in the forms required under SEC rules for periodic reports;
provided, however, that Cal Dive may continue to revise such Annual Financial
Statements prior to the filing thereof in order to make corrections and non-substantive changes
which corrections and changes will be delivered by Cal Dive to Helix as soon as practicable, and in
any event within eight (8) hours thereafter; provided, further, that Helix and Cal
Dive financial Representatives will actively consult with each other regarding any changes (whether
or not substantive) which Cal Dive may consider making to the Annual Financial Statements and
related disclosures during the three (3) Business Days immediately prior to any anticipated filing
with the SEC, with particular focus on any changes which would have an effect upon Helix’s
financial statements or related disclosures. In addition to the foregoing, no Annual Financial
Statement or any other document which refers to, or contains information not previously publicly
disclosed with respect to, Helix’s ownership interest in Cal Dive or the Separation will be filed
with the SEC or otherwise made public by any Cal Dive Group member without the prior written
consent of Helix, except to the extent required by applicable law. In any event, Cal Dive will
deliver to Helix, no later than three (3) Business Days prior to the date on which Helix has
notified Cal Dive that Helix intends to file its annual financial statements with the SEC, the
final form of the Annual Financial Statements accompanied by an opinion thereon by Cal Dive’s
independent certified public accountants. Notwithstanding anything to the contrary in this
Section 4.1(a)(v), Cal Dive will file the Annual Financial Statements with the SEC on the
same date and at substantially the same time that Helix files its annual financial statements with
the SEC unless otherwise required by applicable law.

     (vi) Affiliate Financial Statements. Cal Dive will deliver to Helix all Quarterly
Financial Statements and Annual Financial Statements of each Cal Dive Affiliate which is itself
required to file financial statements with the SEC or otherwise make such financial statements
publicly available, with such financial statements to be provided in the same manner and detail and
on the same time schedule as those financial statements of Cal Dive required to be delivered to
Helix pursuant to this Section 4.1.

-24-

 

     (vii) Conformance with Helix Financial Presentation. All information provided by any
Cal Dive Group member to Helix or filed with the SEC pursuant to Sections 4.1(a)(iii)
through (vi) inclusive will be consistent in terms of format and detail and otherwise with
Helix’s policies with respect to the application of GAAP and practices in effect on the Closing
Date with respect to the provision of such financial information by such Cal Dive Group member to
Helix (and, where appropriate, as presently presented in financial reports to Helix’s board of
directors), with such changes therein as may be requested by Helix from time to time consistent
with changes in such accounting principles and practices.

     (viii) Cal Dive Reports Generally. Each Cal Dive Group member that files information
with the SEC will deliver to Helix: (A) substantially final drafts, as soon as the same are
prepared, of (x) all reports, notices and proxy and information statements to be sent or made
available by such Cal Dive Group member to its respective security holders, (y) all regular,
periodic and other reports to be filed or furnished under Sections 13, 14 and 15 of the Exchange
Act (including Reports on Forms 10-K, 10-Q and 8-K and Annual Reports to Shareholders), and (z) all
registration statements and prospectuses to be filed by such Cal Dive Group member with the SEC or
any securities exchange pursuant to the listed company manual (or similar requirements) of such
exchange (collectively, the documents identified in clauses (x), (y) and
(z) above are referred to as the “Cal Dive Public Documents”); and (B) as soon as
practicable, but in no event later than four (4) Business Days (other than with respect to Current
Reports on Form 8-K) prior to the earliest of the dates the same are printed, sent or filed,
current drafts of all such Cal Dive Public Documents and, with respect to Current Reports on Form
8-K, as soon as practicable, but in no event later than two (2) Business Days prior to the earliest
of the dates the same are printed, sent or filed in the case of planned Current Reports on Form 8-K
and as soon as practicable, but in no event less than two (2) hours in the case of unplanned
Current Reports on Form 8-K; provided, however, that Cal Dive may continue to
revise such Cal Dive Public Documents prior to the filing thereof in order to make corrections and
non-substantive changes which corrections and changes will be delivered by Cal Dive to Helix as
soon as practicable, and in any event within eight (8) hours thereafter; provided,
further, that Helix and Cal Dive financial Representatives will actively consult with each
other regarding any changes (whether or not substantive) which Cal Dive may consider making to any
of its Cal Dive Public Documents and related disclosures prior to any anticipated filing with the
SEC, with particular focus on any changes which would have an effect upon Helix’s financial
statements or related disclosures. In addition to the foregoing, no Cal Dive Public Document or any
other document which refers to, or contains information not previously publicly disclosed with
respect to, Helix’s ownership interest in Cal Dive or the Separation will be filed with the SEC or
otherwise made public by any Cal Dive Group member without the prior written consent of Helix,
except as required by applicable law.

     (ix) Budgets and Financial Projections. Cal Dive will, as promptly as practicable,
deliver to Helix copies of all annual and other budgets and financial projections (consistent in
terms of format and detail and otherwise required by Helix) relating to the Cal Dive Group on a
consolidated basis and will provide Helix an

-25-

 

opportunity to meet with management of Cal Dive to discuss such budgets and projections.

     (x) Other Information. With reasonable promptness, Cal Dive will deliver to Helix
such additional financial and other information and data with respect to the Cal Dive Group and
their business, properties, financial positions, results of operations and prospects as from time
to time may be reasonably requested by Helix.

     (xi) Press Releases and Similar Information. Cal Dive and Helix will consult with
each other as to the timing of their annual and quarterly earnings releases and any interim
financial guidance for a current or future period and will give each other the opportunity to
review the information therein relating to the Cal Dive Group and to comment thereon. Helix and Cal
Dive will make commercially reasonable efforts to issue their respective annual and quarterly
earnings releases at approximately the same time on the same date. No later than eight (8) hours
prior to the time and date that a party intends to publish its regular annual or quarterly earnings
release or any financial guidance for a current or future period, such party will deliver to the
other party copies of substantially final drafts of all press releases and other statements to be
made available by any member of that party’s Group to employees of any member of that party’s Group
or to the public concerning any matters that could be reasonably likely to have a material
financial impact on the earnings, results of operations, financial condition or prospects of any
Cal Dive Group member. In addition, prior to the issuance of any such press release or public
statement that meets the criteria set forth in the preceding two sentences, the issuing party will
consult with the other party regarding any changes (other than typographical or other similar minor
changes) to such substantially final drafts. Immediately following the issuance thereof, the
issuing party will deliver to the other party copies of final drafts of all press releases and
other public statements.

     (xii) Cooperation on Helix Filings. Cal Dive will cooperate fully, and will cause Cal
Dive Auditors to cooperate fully, with Helix to the extent requested by Helix in the preparation of
Helix’s public earnings or other press releases, Quarterly Reports on Form 10-Q, Annual Reports to
Shareholders, Annual Reports on Form 10-K, any Current Reports on Form 8-K and any other proxy,
information and registration statements, reports, notices, prospectuses and any other filings made
by Helix with the SEC, any national securities exchange or otherwise made publicly available
(collectively, the “Helix Public Filings”). Cal Dive agrees to provide to Helix all
information that Helix reasonably requests in connection with any Helix Public Filings or that, in
the judgment of Helix’s legal department, is required to be disclosed or incorporated by reference
therein under any law, rule or regulation. Cal Dive will provide such information in a timely
manner on the dates requested by Helix (which may be earlier than the dates on which Cal Dive
otherwise would be required hereunder to have such information available) to enable Helix to
prepare, print and release all Helix Public Filings on such dates as Helix will determine but in no
event later than as required by applicable law. Cal Dive will use commercially reasonable efforts
to cause Cal Dive Auditors to consent to any reference to them as experts in any Helix Public
Filings required under any law, rule or regulation. If and to the extent requested by Helix, Cal
Dive will diligently and promptly review all drafts of such Helix Public Filings and prepare in a
diligent and

-26-

 

timely fashion any portion of such Helix Public Filing pertaining to Cal Dive. Prior to any
printing or public release of any Helix Public Filing, an appropriate executive officer of Cal Dive
will, if requested by Helix, certify that the information relating to any Cal Dive Group member or
the Cal Dive Business in such Helix Public Filing is accurate, true, complete and correct in all
material respects. Unless required by law, rule or regulation, Cal Dive will not publicly release
any financial or other information which conflicts with the information with respect to any Cal
Dive Group member or the Cal Dive Business that is included in any Helix Public Filing without
Helix’s prior written consent. Prior to the release or filing thereof, Helix will provide Cal Dive
with a draft of any portion of a Helix Public Filing containing information relating to the Cal
Dive Group and will give Cal Dive an opportunity to review such information and comment thereon;
provided that, Helix will determine in its sole and absolute discretion the final
form and content of all Helix Public Filings.

     (b) Auditors and Audits; Annual Statements and Accounting. Cal Dive agrees that, for
so long as Helix is required to either consolidate the results of operations and financial position
of Cal Dive and any members of the Cal Dive Group, or to account for its investment in Cal Dive
under the equity method of accounting (in accordance with GAAP and consistent with SEC reporting
requirements):

     (i) Selection of Cal Dive Auditors. Unless required by law, Cal Dive will not select
a different accounting firm than Ernst & Young LLP (or its affiliate accounting firms) (unless so
directed by Helix in accordance with a change by Helix in its accounting firm) to serve as its (and
the Cal Dive Group’s) independent certified public accountants (“Cal Dive Auditors”),
without Helix’s prior written consent (which will not be unreasonably withheld); provided,
however, that, to the extent any members of the Cal Dive Group are currently using a
different accounting firm to serve as their independent certified public accountants, such members
of the Cal Dive Group may continue to use such accounting firm provided such accounting firm is
reasonably satisfactory to Helix.

     (ii) Audit Timing. Cal Dive will use commercially reasonable efforts to enable Cal
Dive Auditors to complete their audit such that they will be able to date their opinion on the
Annual Financial Statements on the same date that Helix’s independent certified public accountants
(“Helix Auditors”) date their opinion on Helix’s audited annual financial statements (the
“Helix Annual Statements”), and to enable Helix to meet its schedule for the printing,
filing and public dissemination of the Helix Annual Statements, all in accordance with Section
4.1(a) hereof and as required by applicable law.

     (iii) Information Needed by Helix. Cal Dive will provide to Helix on a timely basis
all information that Helix reasonably requires to meet its schedule for the preparation, printing,
filing, and public dissemination of the Helix Annual Statements in accordance with Section
4.1(a) hereof and as required by applicable law. Without limiting the generality of the
foregoing, Cal Dive will provide all required financial information with respect to the Cal Dive
Group to Cal Dive Auditors in a sufficient and reasonable time and in sufficient detail to permit
Cal Dive Auditors to take all steps and

-27-

 

perform all reviews necessary to provide sufficient assistance to Helix Auditors with respect
to information to be included or contained in the Helix Annual Statements.

     (iv) Access to Cal Dive Auditors. Cal Dive will authorize Cal Dive Auditors to make
available to Helix Auditors the personnel who performed, or are performing, the annual audit of Cal
Dive as well as the work papers related to the annual audit of Cal Dive, in all cases within a
reasonable time prior to the date of the Cal Dive Auditors’ opinion on the Annual Financial
Statements, so that Helix Auditors are able to perform the procedures they consider necessary to
take responsibility for the work of Cal Dive Auditors as it relates to Helix Auditors’ report on
the Helix Annual Statements, all within sufficient time to enable Helix to meet its schedule for
the preparation, printing, filing and public dissemination of the Helix Annual Statements.

     (v) Access to Records. If Helix determines in good faith that there may be any
inaccuracy in a Cal Dive Group member’s financial statements or deficiency in a Cal Dive Group
member’s internal accounting controls or operations that could materially impact Helix’s financial
statements, at Helix’s request, Cal Dive will provide Helix’s internal auditors with access to the
Cal Dive Group’s books and records so that Helix may conduct reasonable audits relating to the
financial statements provided by Cal Dive under this Agreement as well as to the internal
accounting controls and operations of the Cal Dive Group.

     (vi) Notice of Changes. Subject to Section 4.1(a)(vii), Cal Dive will give
Helix as much prior notice as reasonably practicable of any proposed determination of, or any
significant changes in, Cal Dive’s accounting estimates or accounting principles from those in
effect on the Closing Date. Cal Dive will consult with Helix and, if requested by Helix, Cal Dive
will consult with Helix Auditors with respect thereto. Cal Dive will not make any such
determination or changes without Helix’s prior written consent if such a determination or a change
would be sufficiently material to be required to be disclosed in Cal Dive’s or Helix’s financial
statements as filed with the SEC or otherwise publicly disclosed therein.

     (vii) Accounting Changes Requested by Helix. Notwithstanding Section
4(a)(vi), Cal Dive will make any changes in its accounting estimates or accounting principles
that are requested by Helix in order for Cal Dive’s accounting practices and principles to be
consistent with those of Helix.

     (viii) Special Reports of Deficiencies or Violations. Cal Dive will report in
reasonable detail to Helix the following events or circumstances promptly after any executive
officer of Cal Dive or any member of the Cal Dive board of directors becomes aware of such matter:
(A) all significant deficiencies and material weaknesses in the design or operation of internal
control over financial reporting which are reasonably likely to adversely affect Cal Dive’s ability
to record, process, summarize and report financial information; (B) any fraud, whether or not
material, that involves management or other employees who have a significant role in Cal Dive’s
internal control over financial reporting; (C) any illegal act within the meaning of Section 10A(b)
and (f) of the Exchange Act; and (D) any report of a material violation of law that an attorney

-28-

 

representing any Cal Dive Group member has formally made to any officers or directors of Cal
Dive pursuant to the SEC’s attorney conduct rules (17 C.F.R. Part 205).

     4.2 Agreement for Exchange of Information; Archives.

     (a) Each of Helix and Cal Dive, on behalf of its respective Group, agrees to provide, or cause
to be provided, to the other Group, at any time before or after the Closing Date, as soon as
reasonably practicable after written request therefor, any Information in the possession or under
the control of such respective Group which the requesting party reasonably needs (i) to comply with
reporting, disclosure, filing or other requirements imposed on the requesting party (including
under applicable securities or tax Laws) by a Governmental Authority having jurisdiction over the
requesting party, (ii) for use in any other judicial, regulatory, administrative, tax or other
proceeding or in order to satisfy audit, accounting, claim, regulatory, litigation, tax or other
similar requirements, in each case other than claims or allegations that one party to this
Agreement has against the other, or (iii) subject to the foregoing clause (ii), to comply with its
obligations under this Agreement or any Transaction Document; provided, however,
that in the event that any party reasonably determines that any such provision of Information could
be commercially detrimental, violate any Law or agreement, or waive any attorney-client privilege,
the parties shall take all commercially reasonable measures to permit the compliance with such
obligations in a manner that avoids any such harm or consequence.

     (b) After the Closing Date, Cal Dive shall have access during regular business hours (as in
effect from time to time) to the documents and objects of historic significance that relate to the
Cal Dive Business that are located in archives retained or maintained by any member of the Helix
Group. Cal Dive may obtain copies (but not originals unless it is a Cal Dive Asset) of documents
for bona fide business purposes and may obtain objects for exhibition purposes for commercially
reasonable periods of time if required for bona fide business purposes; provided
that, Cal Dive shall cause any such objects to be returned promptly in the same condition
in which they were delivered to Cal Dive, and Cal Dive shall comply with any rules, procedures or
other requirements, and shall be subject to any restrictions (including prohibitions on removal of
specified objects), that are then applicable to Helix. Cal Dive shall pay the applicable fee or
rate per hour for archive research services (subject to increase from time to time to reflect rates
then in effect for Helix generally). Nothing herein shall be deemed to restrict the access of any
member of the Helix Group to any such documents or objects or to impose any liability on any member
of the Helix Group if any such documents or objects are not maintained or preserved by Helix.

     (c) After the Closing Date, Helix shall have access during regular business hours (as in
effect from time to time) to the documents and objects of historic significance that relate to the
businesses of any member of the Helix Group that are located in archives retained or maintained by
any member of the Cal Dive Group. Helix may obtain copies (but not originals unless it is not a
Cal Dive Asset) of documents for bona fide business purposes and may obtain objects for exhibition
purposes for commercially reasonable periods of time if required for bona fide business purposes;
provided that, Helix shall cause any such objects to be returned promptly in the
same condition in which they were delivered to Helix, and Helix shall comply with any rules,
procedures or other requirements, and shall be subject to any restrictions (including prohibitions
on removal of specified objects), that are then applicable to Cal Dive. Helix shall pay the

-29-

 

applicable fee or rate per hour for archive research services (subject to increase from time
to time to reflect rates then in effect for Cal Dive generally). Nothing herein shall be deemed to
restrict the access of any member of the Cal Dive Group to any such documents or objects or to
impose any liability on any member of the Cal Dive Group if any such documents or objects are not
maintained or preserved by Cal Dive.

     (d) The obligations of the parties under this Section 4.2 shall terminate on the fifth
(5th) anniversary of the Trigger Date.

     4.3 Ownership of Information.

     Any Information owned by a member of a Group that is provided to a requesting party pursuant
to Section 4.2 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.

     4.4 Compensation for Providing Information.

     The party requesting Information agrees to reimburse the party providing Information for the
reasonable out-of-pocket costs, if any, of creating, gathering and copying such Information, to the
extent that such costs are incurred for the benefit of the requesting party. Except as may be
otherwise specifically provided elsewhere in this Agreement, the Transaction Documents or in any
other agreement between the parties, such costs shall be computed in accordance with the providing
party’s standard methodology and procedures.

     4.5 Record Retention.

     To facilitate the possible exchange of Information pursuant to this Article IV and other
provisions of this Agreement and the Transaction Documents, after the Closing Date, the parties
agree to use commercially reasonable efforts to retain all Information in their respective
possession or control in accordance with the policies of Helix as in effect on the Closing Date or
such other policies as may be reasonably adopted by the appropriate party after the Closing Date.
No party will destroy, or permit any of its Subsidiaries to destroy, any Information which the
other party may have the right to obtain pursuant to this Agreement prior to the fifth
(5th) anniversary of the Trigger Date without first notifying the other party of the
proposed destruction and giving the other party the opportunity to take possession of such
Information prior to such destruction; provided, however, that in the case of any Information
relating to Taxes or employee benefits, such period shall be extended to the expiration of the
applicable statute of limitations (giving effect to any extensions thereof); provided, further,
however, no party will destroy, or permit any of its Subsidiaries to destroy, any Information
required to be retained by applicable Law.

     4.6 Liability.

     No party shall have any liability to any other party in the event that any Information
exchanged or provided pursuant to this Agreement which is an estimate or forecast, or which is
based on an estimate or forecast, is found to be inaccurate in the absence of willful misconduct by
the party providing such Information. No party shall have any liability to any other party if

-30-

 

any Information is destroyed after commercially reasonable efforts by such party to comply
with the provisions of Section 4.5.

     4.7 Other Agreements Providing for Exchange of Information.

     (a) The rights and obligations granted under this Article IV are subject to any
specific limitations, qualifications or additional provisions on the sharing, exchange, retention
or confidential treatment of Information set forth in any Transaction Document.

     (b) When any Information provided by one Group to the other Group (other than Information
provided pursuant to Section 4.5) is no longer needed for the purposes contemplated by this
Agreement or any other Transaction Document or is no longer required to be retained by applicable
Law, the receiving party will promptly after request of the other party either return to the other
party all Information in a tangible form (including all copies thereof and all notes, extracts or
summaries based thereon) or certify to the other party that it has destroyed such Information (and
such copies thereof and such notes, extracts or summaries based thereon).

     4.8 Production of Witnesses; Records; Cooperation.

     (a) After the Closing Date, except in the case of an adversarial Action by one or more members
of one Group against one or more members of the other Group, each party hereto shall use
commercially reasonable efforts to make available to each other party, upon written request, the
former, current and future directors, officers, employees, other personnel and agents of the
members of its respective Group as witnesses and 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
Action in which the requesting party may from time to time be involved, regardless of whether such
Action is a matter with respect to which indemnification may be sought hereunder. The requesting
party shall bear all costs and expenses in connection therewith.

     (b) If an Indemnifying Party chooses to defend or to seek to compromise or settle any Third
Party Claim, the parties shall make available to such Indemnifying Party, upon written request, the
former, current and future directors, officers, employees, other personnel and agents of the
members of its respective Group as witnesses and 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 such
defense, settlement or compromise, or the prosecution, evaluation or pursuit thereof, as the case
may be, and shall otherwise cooperate in such defense, settlement or compromise, or such
prosecution, evaluation or pursuit, as the case may be.

     (c) Without limiting the foregoing, the parties shall cooperate and consult to the extent
reasonably necessary with respect to any Actions, except in the case of an adversarial Action by
one or more members of one Group against one or more members of the other Group.

-31-

 

     (d) Without limiting any provision of this Section, each of the parties agrees to cooperate,
and to cause each member of its respective Group to cooperate, with each other in the defense of
any infringement or similar claim with respect to any intellectual property and shall not claim to
acknowledge, or permit any member of its respective Group to claim to acknowledge, the validity or
infringing use of any intellectual property of a third Person in a manner that would hamper or
undermine the defense of such infringement or similar claim except as required by Law.

     (e) The obligation of the parties to provide witnesses pursuant to this Section 4.8 is
intended to be interpreted in a manner so as to facilitate cooperation and shall include the
obligation to provide as witnesses inventors and other officers without regard to whether the
witness or the employer of the witness could assert a possible business conflict (subject to the
exception set forth in the first sentence of Section 4.8(a)).

     (f) In connection with any matter contemplated by this Section 4.8, the parties will
enter into a mutually acceptable joint defense agreement so as to maintain to the extent
practicable any applicable attorney-client privilege, work product immunity or other applicable
privileges or immunities of any member of any Group.

     (g) The obligations of the parties under this Section 4.8 shall terminate on the fifth
(5th) anniversary of the Trigger Date.

     4.9 Privilege.

     The provision of any information pursuant to this Article IV shall not be deemed a
waiver of any privilege, including privileges arising under or related to the attorney-client
privilege or any other applicable privileges (a “Privilege”). Following the Closing Date,
neither Cal Dive or its Subsidiaries nor Helix or its Subsidiaries will be required to provide any
information pursuant to this Article IV if the provision of such information would serve as
a waiver of any Privilege afforded such information.

     (c) Nothing contained in Section 5.1(a) or Section 5.1(b) shall impair any
right of any Person to enforce this Agreement, any Transaction Document or any agreements,
arrangements, commitments or understandings to continue in effect after the Closing Date in
accordance with Section 2.4(b), in each case in accordance with its terms. Nothing
contained in Section 5.1(a) or Section 5.1(b) shall release any Person from:

          (v) any Liability that the parties may have with respect to indemnification or contribution
pursuant to this Agreement or otherwise for claims brought against the parties by third Persons,
which Liability shall be governed by the provisions of this Article V and, if applicable,
the appropriate provisions of the Transaction Documents.

     In addition, nothing contained in Section 5.1(a) shall release Helix from indemnifying
any director, officer or employee of Cal Dive who was a director, officer or employee of Helix or
any of its Affiliates on or prior to the Closing Date, to the extent such director, officer or
employee is or becomes a named defendant in any Action with respect to which he or she was entitled
to such indemnification pursuant to then existing obligations.

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

Person released pursuant to Section 5.1(a), with respect to any Liabilities released

occurred or to have failed to occur and all conditions existing or alleged to have existed on or
before the Closing Date, whether known or unknown, between or among Cal Dive or any member of the
Cal Dive Group, on the one hand, and Helix or any member of the Helix 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 Closing Date), except as expressly set forth in Sections 5.1
(a), (b) and (c). At any time, at the request of any other party, each party shall
cause each member of its respective Group and each other Person on whose behalf it released
Liabilities pursuant to this Section 5.1 to execute and deliver releases reflecting the
provisions hereof.

     5.2 General Indemnification by Cal Dive.

     Except as provided in Section 5.5, Cal Dive shall, and shall cause the other members
of the Cal Dive Group to, jointly and severally, indemnify, defend and hold harmless on an
After-Tax Basis each member of the Helix Group and each of their respective directors, officers and
employees, and each of the heirs, executors, successors and assigns of any of the foregoing
(collectively, the “Helix Indemnified Parties”), from and against any and all Liabilities
of the Helix Indemnified Parties relating to, arising out of or resulting from any of the following
items (without duplication):

-34-

 

     (a) the failure of Cal Dive or any other member of the Cal Dive Group or any other Person to
pay, perform or otherwise promptly discharge any Cal Dive Liabilities or Cal Dive Contract in
accordance with its respective terms, whether prior to or after the Closing Date;

     (b) any Cal Dive Liability or any Cal Dive Contract;

     (c) except to the extent it relates to an Excluded Liability, any guarantee, indemnification
obligation, surety bond or other credit support agreement, arrangement, commitment or understanding
by any member of the Helix Group for the benefit of any member of the Cal Dive Group that survives
the Closing;

     (d) any breach by any member of the Cal Dive Group of this Agreement or any of the Transaction
Documents or any action by Cal Dive in contravention of the Charter or Bylaws; and

     (e) any untrue statement or alleged untrue statement of a material fact contained in any Helix
Public Filing or any other document filed with the SEC by any member of the Helix Group pursuant to
the Securities Act or the Exchange Act, or any omission or alleged omission to state therein a
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, in each case to the extent, but
only to the extent, that those Liabilities are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information that is either furnished to any member
of the Helix Group by any member of the Cal Dive Group or incorporated by reference by any member
of the Helix Group from any filings made by any member of the Cal Dive Group with the SEC pursuant
to the Securities Act or the Exchange Act, and then only if that statement or omission was made or
occurred after the Closing Date.

     5.3 General Indemnification by Helix.

     Except as provided in Section 5.5, Helix shall indemnify, defend and hold harmless on
an After-Tax Basis each member of the Cal Dive Group and each of their respective directors,
officers and employees, and each of the heirs, executors, successors and assigns of any of the
foregoing (collectively, the “Cal Dive Indemnified Parties”), from and against any and all
Liabilities of the Cal Dive Indemnified Parties relating to, arising out of or resulting from any
of the following items (without duplication):

     (a) the failure of any member of the Helix Group or any other Person to pay, perform or
otherwise promptly discharge any Liabilities of the Helix Group other than the Cal Dive
Liabilities, whether prior to or after the Closing Date or the date hereof;

     (b) any Excluded Liability or any Liability of a member of the Helix Group other than the Cal
Dive Liabilities;

     (c) any breach by any member of the Helix Group of this Agreement or any of the Transaction
Documents; and

     (d) any untrue statement or alleged untrue statement of a material fact contained in any
document filed with the SEC by any member of the Cal Dive Group pursuant to the Securities Act or
the Exchange Act other than the IPO Registration Statement or Prospectus, or

-35-

 

any omission or alleged omission to state therein a 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, in each case to the extent, but only to the extent, that those
Liabilities are caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information that is either furnished to any member of the Cal Dive Group by any
member of the Helix Group or incorporated by reference by any member of the Cal Dive Group from any
Helix Public Filings or any other document filed with the SEC by any member of the Helix Group
pursuant to the Securities Act or the Exchange Act, and then only if that statement or omission was
made or occurred after the Closing Date.

     5.4 Registration Statement Indemnification.

     (a) Cal Dive agrees to indemnify and hold harmless on an After-Tax Basis the Helix Indemnified
Parties and each Person, if any, who controls any member of the Helix Group within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all
Liabilities arising out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in the IPO Registration Statement or Prospectus, or arising out of or based
upon 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, except to the extent such
Liabilities arise out of or are based upon any untrue statement or omission or alleged untrue
statement or omission which has been made therein or omitted therefrom in reliance upon and in
conformity with information provided by a member of the Helix Group expressly for use in the IPO
Registration Statement or Prospectus or information relating to any underwriter furnished to Cal
Dive by or on behalf of such underwriter expressly for use in the IPO Registration Statement or
Prospectus.

     (b) Helix agrees to indemnify and hold harmless on an After-Tax Basis Cal Dive and its
Subsidiaries and any of their respective directors or officers who sign the IPO Registration
Statement, and any person who controls Cal Dive within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act, from and against any and all Liabilities arising out of or
based upon any untrue statement or alleged untrue statement of a material fact contained in the IPO
Registration Statement or Prospectus, or arising out of or based upon 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 only to the extent that such Liabilities arise out of or are
based upon any untrue statement or omission or alleged untrue statement or omission with respect to
information provided by a Helix Group member expressly for use in the IPO Registration Statement or
Prospectus.

     5.5 Contribution.

     (a) If the indemnification provided for in this Article V is unavailable to, or
insufficient to hold harmless on an After-Tax Basis, an Indemnified Party under Section
5.2(e), Section 5.3(d) or Section 5.4 in respect of any Liabilities referred to
therein, then each Indemnifying Party shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Liabilities in such proportion as is appropriate to reflect
the relative fault of the Indemnifying Party and the Indemnified Party in connection with the
actions or omissions that resulted in Liabilities as well as any other relevant equitable
considerations. The relative fault of

-36-

 

such Indemnifying Party and Indemnified Party shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by such Indemnifying Party or
Indemnified Party, and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. For purposes of this Section
5.5(a), the information set forth in the IPO Registration Statement that is described on
Schedule 5.4(a) shall be the only “information supplied by” any member of the Helix Group.

     (b) The parties agree that it would not be just and equitable if contribution pursuant to this
Section 5.5 were determined by a pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to in Section 5.5(a).
The amount paid or payable by an Indemnified Party as a result of the Liabilities referred to in
Section 5.5(a) shall be deemed to include, subject to the limitations set forth above, any
legal or other fees or expenses reasonably incurred by such Indemnified Party in connection with
investigating any claim or defending any Action. Notwithstanding the provisions of this
Section 5.5, Helix shall not be required to contribute any amount that, together with the
amount of any damages that Helix has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, exceeds the benefits received solely by
Helix from the Initial Public Offering (excluding benefits received by the Company and all other
parties). 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.

     5.6 Indemnification Obligations Net of Insurance Proceeds and Other Amounts on an
After-Tax Basis.

     (a) Any Liability subject to indemnification or contribution pursuant to this Article
V will be net of Insurance Proceeds that actually reduce the amount of the Liability and will
be determined on an After-Tax Basis. Accordingly, the amount which any Person is required to pay
pursuant to this Article V (an “Indemnifying Party”) to any Person entitled to
indemnification or contribution pursuant to this Article V (an “Indemnified Party”)
will be reduced by any Insurance Proceeds theretofore actually recovered by or on behalf of the
Indemnified Party in respect of the related Liability. If an Indemnified Party receives a payment
required by this Agreement from an Indemnifying Party in respect of any Liability (an
“Indemnity Payment”) and subsequently receives Insurance Proceeds, then the Indemnified
Party will pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment
received over the amount of the Indemnity Payment that would have been due if the Insurance
Proceeds had been received, realized or recovered before the Indemnity Payment was made.

     (b) An insurer who would otherwise be obligated to pay any claim shall not be relieved of the
responsibility with respect thereto or, solely by virtue of the indemnification and contribution
provisions hereof, have any subrogation rights with respect thereto. The Indemnified Party shall
use commercially reasonable efforts to seek to collect or recover any third-party Insurance
Proceeds (other than Insurance Proceeds under an arrangement where future premiums are adjusted to
reflect prior claims in excess of prior premiums) to which the Indemnified Party is entitled in
connection with any Liability for which the Indemnified Party seeks contribution or indemnification
pursuant to this Article V; provided that, the Indemnified

-37-

 

Party’s inability to collect or recover any such Insurance Proceeds shall not limit the
Indemnifying Party’s obligations hereunder.

     (c) The term “After-Tax Basis” as used in this Article V means that, in
determining the amount of the payment necessary to indemnify any party against, or reimburse any
party for, Liabilities, the amount of such Liabilities will be determined net of any reduction in
Tax derived by the Indemnified Party as the result of sustaining or paying such Liabilities, and
the amount of such Indemnity Payment will be increased (i.e., “grossed up”) by the amount necessary
to satisfy any income or franchise Tax liabilities incurred by the Indemnified Party as a result of
its receipt of, or right to receive, such Indemnity Payment (as so increased), so that the
Indemnified Party is put in the same net after-Tax economic position as if it had not incurred such
Liabilities, in each case without taking into account any impact on the tax basis that an
Indemnified Party has in its assets.

     5.7 Procedures for Indemnification of Third Party Claims.

     (a) If an Indemnified Party shall receive notice or otherwise learn of the assertion by a
Person (including any Governmental Authority) who is not a member of the Helix Group or the Cal
Dive Group of any claim 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 Indemnified Party pursuant to Section 5.2, Section
5.3 or Section 5.4, or any other Section of this Agreement or any Transaction Document,
such Indemnified Party shall give such Indemnifying Party written notice thereof within 20 days
after becoming aware of such Third Party Claim. Any such notice shall describe the Third Party
Claim in reasonable detail. Notwithstanding the foregoing, the failure of any Indemnified Party or
other Person to give notice as provided in this Section 5.7(a) shall not relieve the
Indemnifying Party of its obligations under this Article V, 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 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 receipt of notice from an Indemnified Party in accordance with
Section 5.7(a) (or sooner, if the nature of such Third Party Claim so requires), an
Indemnifying Party electing to defend a Third Party Claim shall notify the Indemnified Party of its
election to assume responsibility for defending such Third Party Claim and shall acknowledge and
agree in writing that if such Third Party Claim is adversely determined, such Indemnifying Party
will have the obligation to indemnify the Indemnified Party in respect of all liabilities relating
to, arising out of or resulting from such Third Party Claim and that such Indemnifying Party
irrevocably waives in full all defenses it may have to contest such obligation. After such notice
and acknowledgment from an Indemnifying Party to an Indemnified Party of its election to assume the
defense of a Third Party Claim, such Indemnified 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 the expense of such Indemnified Party.

     (c) If an Indemnifying Party elects not to assume responsibility for defending a Third Party
Claim, or fails to notify an Indemnified Party of its election as provided in Section
5.7(b),

-38-

 

such Indemnified Party may defend such Third Party Claim at the cost and expense of the
Indemnifying Party.

     (d) Unless the Indemnifying Party has failed to assume the defense of the Third Party Claim in
accordance with the terms of this Agreement, no Indemnified Party may settle or compromise any
Third Party Claim without the consent of the Indemnifying Party. No Indemnifying Party shall
consent to entry of any judgment or enter into any settlement of any pending or threatened Third
Party Claim in respect of which any Indemnified Party is or could have been a party and indemnity
could have been sought hereunder by such Indemnified Party without the consent of the Indemnified
Party if (i) the effect thereof is to permit any injunction, declaratory judgment, other order or
other nonmonetary relief to be entered, directly or indirectly against such Indemnified Party and
(ii) such settlement does not include a full, complete and unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of such Third Party
Claim.

     5.8 Additional Matters.

     (a) Indemnification or contribution payments in respect of any Liabilities for which an
Indemnified Party is entitled to indemnification or contribution under this Article V shall
be paid by the Indemnifying Party to the Indemnified Party as such Liabilities are incurred upon
demand by the Indemnified Party, including reasonably satisfactory documentation setting forth the
basis for the amount of such indemnification or contribution payment, including documentation with
respect to calculations made on an After-Tax Basis and consideration of any Insurance Proceeds that
actually reduce the amount of such Liabilities. The indemnity and contribution agreements
contained in this Article V shall remain operative and in full force and effect, regardless
of (i) any investigation made by or on behalf of any Indemnified Party; (ii) the knowledge by the
Indemnified Party of Liabilities for which it might be entitled to indemnification or contribution
hereunder; and (iii) any termination of this Agreement.

     (b) Any claim on account of a Liability which does not result from a Third Party Claim shall
be asserted by written notice given by the Indemnified Party to the applicable Indemnifying Party.
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 Indemnified Party shall be free to pursue such remedies as may be available
to such party as contemplated by this Agreement and the Transaction Documents without prejudice to
its continuing rights to pursue indemnification or contribution hereunder.

     (c) If payment is made by or on behalf of any Indemnifying Party to any Indemnified Party in
connection with any Third Party Claim, such Indemnifying Party shall be subrogated to and shall
stand in the place of such Indemnified Party as to any events or circumstances in respect of which
such Indemnified Party may have any right, defense or claim relating to such Third Party Claim
against any claimant or plaintiff asserting such Third Party Claim or against any other Person.
Such Indemnified Party shall cooperate with such Indemnifying Party in a

-39-

 

reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any
subrogated right, defense or claim.

     (d) In 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 they conclude that substitution is desirable and
practical. 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 V, and the Indemnifying Party shall fully indemnify the named defendant against all costs
of defending the Action (including court costs, sanctions imposed by a court, attorneys’ fees,
experts fees and all other external expenses), the costs of any judgment or settlement, and the
costs of any interest or penalties relating to any judgment or settlement.

     5.9 Remedies Cumulative; Limitations of Liability.

     The rights provided in this Article V shall be cumulative and, subject to the
provisions of Article VII, shall not preclude assertion by any Indemnified Party of any
other rights or the seeking of any and all other remedies against any Indemnifying Party.
NOTWITHSTANDING THE FOREGOING, NO INDEMNIFYING PARTY, SHALL BE LIABLE TO AN INDEMNIFIED PARTY FOR
ANY SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE, CONSEQUENTIAL, EXEMPLARY, STATUTORILY-ENHANCED OR
SIMILAR DAMAGES IN EXCESS OF COMPENSATORY DAMAGES (PROVIDED THAT ANY SUCH LIABILITY WITH RESPECT TO
A THIRD PARTY CLAIM SHALL BE CONSIDERED DIRECT DAMAGES) ARISING IN CONNECTION WITH THE
TRANSACTIONS.

     5.10 Survival of Indemnities.

     The rights and obligations of each of Helix and Cal Dive and their respective Indemnified
Parties under this Article V shall survive the sale or other transfer by any party of any
Assets or businesses or the assignment by it of any Liabilities.

ARTICLE VI

OTHER AGREEMENTS

     6.1 Further Assurances.

     (a) In addition to the actions specifically provided for elsewhere in this Agreement, each of
the parties will cooperate with each other and use (and will cause their respective Subsidiaries
and Affiliates to use) commercially reasonable efforts, prior to, on and after the Closing Date, to

commercially reasonable efforts to cause to be executed and delivered, all instruments,
including instruments of conveyance, assignment and transfer, and to make all filings with, and to
obtain all consents, approvals or authorizations of, any Governmental Authority or any other Person
under any permit, license, agreement, indenture or other instrument (including any Consents or
Governmental Approvals), and to take all such other actions as such party may reasonably be
requested to take by any other party hereto from time to time, consistent with the terms of this
Agreement and the Transaction Documents, in order to effectuate the provisions and purposes of this
Agreement and the Transaction Documents and the transfers of the Cal Dive Assets and the assignment
and assumption of the Cal Dive Liabilities and the other transactions contemplated hereby and
thereby. Without limiting the foregoing, each party will, at the reasonable request, cost and
expense of any other party, take such other actions as may be reasonably necessary to vest in such
other party good and marketable title to the Assets allocated to such party under this Agreement or
any of the Transaction Documents, free and clear of any Security Interest, if and to the extent it
is practicable to do so.

     (c) On or prior to the Closing Date, Helix and Cal Dive in their respective capacities as

of the Helix Group and all of such parties’ respective officers, directors, employees, and other
agents and representatives, including attorneys, agents, customers, suppliers, contractors,

“Representatives”), not to, directly or indirectly, disclose, reveal, divulge or
communicate to any Person (other than Representatives of such party or of its Affiliates who
reasonably need to know such information in providing services to any member of the Helix Group) or
use or otherwise exploit for its own benefit or for the benefit of any third party, any Cal Dive
Confidential Information. If any disclosures are made by a member of the Helix Group to its
Representatives in connection with such Representatives providing services to any member of the
Helix Group under this Agreement or any Transaction Document, then the Cal Dive Confidential
Information so disclosed shall be used only as required to perform the services. Helix shall, and
shall cause the other members of the Helix Group to, use the same degree of care to prevent and
restrain the unauthorized use or disclosure of the Cal Dive Confidential Information by any of

documents relating to the Cal Dive Business currently or formerly conducted, or proposed to be
conducted, by any member of the Cal Dive Group furnished to or

any of their Representatives not otherwise permissible hereunder, (ii) such member of the Helix
Group can demonstrate was or became available to such member of the Helix Group from a source other
than Cal Dive or its Affiliates, or (iii) is developed independently by such member of the Helix
Group without reference to the Cal Dive Confidential Information; provided,
however, that, in the case of clause (ii), the source of such information was not
known by such member of the Helix Group to be bound by a confidentiality agreement with, or other
contractual, legal or fiduciary obligation of confidentiality to, Cal Dive or any member of the Cal
Dive Group with respect to such information.

     (b) From and after the Closing, subject to Section 6.2(c) and except as contemplated
by this Agreement or any Transaction Document, Cal Dive shall not, and shall cause the other
members of the Cal Dive Group and all of such parties’ respective Representatives not to, directly
or indirectly, disclose, reveal, divulge or communicate to any Person (other than Representatives
of such party or of its Affiliates who reasonably need to know such information in providing
services to any member of the Cal Dive Group), or use or otherwise exploit for its own benefit or
for the benefit of any third party, any Helix Confidential Information. If any disclosures are
made by a member of the Cal Dive Group to its Representatives in connection with such
Representatives providing services to any member of the Cal Dive Group under this Agreement or any

Group to, use the same degree of care to prevent and restrain the unauthorized use or disclosure of
the Helix Confidential Information by any of their Representatives as they currently use for their
own confidential information of a like nature, but in no event less than a reasonable standard of
care. Any information, material or documents relating to the businesses currently or formerly

Helix or its Affiliates, or (iii) is developed independently by such member of the Cal Dive Group
without reference to the Helix Confidential Information; provided, however, that,
in the case of clause (ii), the source of such information was not known by such member of
the Cal Dive Group to be bound by a confidentiality agreement with, or other contractual, legal or
fiduciary obligation of

-42-

 

confidentiality to, Helix or any other member of the Helix Group with respect to such
information.

     (c) If any member of the Helix Group or their respective Representatives, on the one hand, or
any member of the Cal Dive Group or their respective Representatives, on the other hand, are
requested or required (by oral question, interrogatories, requests for information or documents,
subpoena, civil investigative demand or similar process) by any Governmental Authority or pursuant
to applicable Law to disclose or provide any Cal Dive Confidential Information or Helix
Confidential Information (other than with respect to any such information furnished pursuant to the
provisions of Article IV of this Agreement), as applicable, the entity or person receiving
such request or demand shall use all commercially reasonable efforts to provide the other party
with written notice of such request or demand as promptly as practicable under the circumstances so
that such other party shall have an opportunity to seek an appropriate protective order. The party
receiving such request or demand agrees to take, and cause its representatives to take, at the
requesting party’s expense, all other commercially reasonable steps necessary to obtain
confidential treatment by the recipient. Subject to the foregoing, the party that received such
request or demand may thereafter disclose or provide any Cal Dive Confidential Information or Helix
Confidential Information, as the case may be, to the extent required by such Law (as so advised by
counsel) or by lawful process of such Governmental Authority.

     6.3 Insurance Matters.

     (a) Members of the Cal Dive Group will continue to have coverage under Helix’s insurance
program until the Trigger Date. Members of the Cal Dive Group will be subject to retrospective
premium adjustments under each such Insurance Policy based on their loss experience under the
Insurance Policy and in accordance with Helix’s pricing methodologies. The members of the Cal Dive
Group will have coverage under all Insurance Policies with respect to periods prior to the Trigger
Date in accordance with the terms of each such Insurance Policy. Helix and Cal Dive agree to
cooperate in good faith to provide for an orderly transition of insurance coverage leading up to
the Trigger Date, and for the treatment of any Insurance Policies that will remain in effect
following the Trigger Date on a mutually agreeable basis. Cal Dive may elect to decline or
withdraw from coverage under any Insurance Policy by written notice to Helix at least sixty (60)
days prior to such cancellation. In no event shall Helix, any other member of the Helix Group or
any Helix Indemnified Party have liability or obligation whatsoever to any member of the Cal Dive
Group if any Insurance Policy or other contract or policy of insurance shall be terminated or
otherwise cease to be in effect or for any reason shall be unavailable or inadequate to cover any
Liability of any member of the Cal Dive Group for any reason whatsoever or shall not be renewed or
extended beyond the current expiration date. Helix shall provide notice to Cal Dive promptly upon
its becoming aware that any Insurance Policy has been terminated or is otherwise no longer in
effect or is reasonably likely to be terminated or otherwise cease to be in effect.

     (b) (i) Except as otherwise provided in any Transaction Document, the parties intend by this
Agreement that Cal Dive and each other member of the Cal Dive Group be successors-in-interest to
all rights that any member of the Cal Dive Group may have as of the Closing Date as a subsidiary,
affiliate, division or department of Helix prior to the Closing Date

-43-

 

under any policy of insurance issued to Helix by any insurance carrier or under any agreements
related to such policies executed and delivered prior to the Closing Date, including any rights
such member of the Cal Dive Group may have, as an insured or additional named insured, subsidiary,
affiliate, division or department, to avail itself of any such policy of insurance or any such
agreements related to such policies as in effect prior to the Closing Date. At the request of Cal
Dive, Helix shall take all commercially reasonable steps, including the execution and delivery of
any instruments, to effect the foregoing; provided, however, that Helix shall not
be required to pay any amounts, waive any rights or incur any Liabilities in connection therewith.

               (i) Except as otherwise contemplated by any Transaction Document, after the Closing Date, none
of Helix or Cal Dive or any member of their respective Groups shall, without the consent of the
other, provide any such insurance carrier with a release, or amend, modify or waive any rights
under any such policy or agreement, if such release, amendment, modification or waiver would
adversely affect any rights or potential rights of any member of the other Group thereunder;
provided, however, that the foregoing shall not (A) preclude any member of any
Group from presenting any claim or from exhausting any policy limit, (B) require any member of any
Group to pay any premium or other amount or to incur any Liability, or (C) require any member of
any Group to renew, extend or continue any policy in force. Each of Cal Dive and Helix will share
such information as is reasonably necessary in order to permit the other to manage and conduct its
insurance matters in an orderly fashion.

     (c) This Agreement shall not be considered as an attempted assignment of any policy of
insurance or as a contract of insurance and shall not be construed to waive any right or remedy of
any member of the Helix Group in respect of any Insurance Policy or any other contract or policy of
insurance.

     (d) Cal Dive does hereby, for itself and each other member of the Cal Dive Group, agree that
no member of the Helix Group or any Helix Indemnified Party shall have any Liability whatsoever to
Cal Dive or any other member of the Cal Dive Group as a result of the insurance policies and
practices of Helix and its Affiliates as in effect at any time prior to the Closing Date, including
as a result of the level or scope of any such insurance, the creditworthiness of any insurance
carrier, the terms and conditions of any policy, the adequacy or timeliness of any notice to any
insurance carrier with respect to any claim or potential claim or otherwise.

     (e) Nothing in this Agreement shall be deemed to restrict any member of the Cal Dive Group
from acquiring at its own expense any other insurance policy in respect of any Liabilities or
covering any period; provided that, Cal Dive shall give Helix prompt written notice
of any such insurance policy acquired prior to the Trigger Date.

     6.4 Allocation of Costs and Expenses.

     (a) Helix shall pay (or, to the extent incurred by and paid for by any member of the Cal Dive
Group, will promptly reimburse such party for any and all amounts so paid) for all out-of-pocket
fees, costs and expenses incurred by Helix or Cal Dive, or any member of their respective Groups,
on or prior to the Closing Date in connection with the Separation, including (i) the preparation
and negotiation of this Agreement, each Transfer Document (unless otherwise expressly provided
therein), and all other documentation related to the Separation, (ii) accounting

-44-

 

and legal costs incurred in association with all domestic and international internal
restructuring undertaken as part of the Separation, (iii) the preparation and execution or filing
of any and all other documents, certificates, deeds, titles, agreements, forms, applications or
contracts associated with the Separation, and (iv) the preparation and filing of Cal Dive’s and its
Subsidiaries’ organizational documents.

     (b) Cal Dive shall pay (or, to the extent incurred by and paid or by any member of the Helix
Group, will promptly reimburse such party for any and all amounts so paid) for all out-of-pocket
fees, costs and expenses incurred by Helix or Cal Dive, or any member of their respective Groups,
in connection with the Initial Public Offering and the other Transactions, except as otherwise
provided in Section 6.4(a), including (i) the preparation, printing and filing of the IPO
Registration Statement, (ii) compliance with applicable federal, state or foreign securities Laws
and domestic or foreign securities exchange rules and regulations, together with fees and expenses
of counsel retained to effect such compliance, (iii) the preparation, printing and distribution of
the Prospectus, (iv) the initial listing of the Common Stock on the New York Stock Exchange, (v)
the fees and expenses of Ernst & Young LLP incurred in connection with the IPO Registration
Statement and the Initial Public Offering, and (vi) the preparation (including, but not limited to,
the printing of documents) and implementation of Cal Dive’s and its Subsidiaries’ employee benefit
plans, retirement plans and equity-based plans, and (vii) the preparation and implementation of Cal
Dive’s and its Subsidiaries corporate governance programs and policies, financial reporting and
internal controls and all other reporting requirements, programs, policies and functions required
to be implemented by the Cal Dive Group as a result of being a public company reporting to the SEC
with equity securities listed on a national stock exchange.

     (c) Notwithstanding the foregoing, Helix and Cal Dive agree that all costs and expenses
described in Sections 6.4(a) and (b) may be paid from the proceeds of the Initial
Public Offering.

     6.5 Covenants Against Taking Certain Actions Affecting Helix.

     (a) Cal Dive hereby acknowledges and agrees that it shall not, without the prior written
consent of Helix (which it may withhold in its sole and absolute discretion), take, or cause to be
taken, directly or indirectly, any action, including making or failing to make any election under
the Law of any state, which has the effect, directly or indirectly, of restricting or limiting the
ability of Helix or any of its Affiliates to freely sell, transfer, assign, pledge or otherwise
dispose of Cal Dive Capital Stock. Without limiting the generality of the foregoing, Cal Dive
shall not, without the prior written consent of Helix (which it may withhold in its sole and
absolute discretion), take any action, or recommend to its stockholders any action, which would
among other things, limit the legal rights of, or deny any benefit to, Helix as a Cal Dive
stockholder in a manner not applicable to Cal Dive stockholders generally.

     (b) Prior to the Trigger Date, to the extent that any member of the Helix Group is a party to
any contract or agreement with a third party (i) that provides that certain actions of Helix’s
Subsidiaries may result in Helix being in breach of or in default under such agreement and Helix
has advised Cal Dive, or Cal Dive is otherwise aware, of the existence of such contract or
agreement (or the relevant portions thereof), (ii) to which any member of the Cal Dive Group

-45-

 

is a party or (iii) under which any member of the Cal Dive Group has performed any obligations
on or before the date hereof, Cal Dive shall not take, and shall cause each other member of the Cal
Dive Group not to take, any actions that reasonably could result in any member of the Helix Group
being in breach of or in default under any such contract or agreement. Cal Dive hereby
acknowledges and agrees that Helix has made available to Cal Dive copies of each such contract or
agreement (or the relevant portion thereof) in effect on the date hereof. The parties acknowledge
and agree that, after the date hereof, Helix may in good faith (and not solely with the intention
of imposing restrictions on Cal Dive pursuant to this covenant) amend the referenced agreements or
enter into additional contracts or agreements that provide that certain actions of any member of
the Cal Dive Group may result in Helix being in breach of or in default under such agreements;
provided that, Helix shall notify and consult with Cal Dive prior to entering into
any such amendments or additional contracts or agreements to the extent that compliance therewith
(x) could reasonably be expected to have a material adverse effect on any member of the Cal Dive
Group or (y) would discriminate in an adverse way in the treatment of members of the Cal Dive Group
as compared with Helix and its other Affiliates, and shall make available to Cal Dive copies of
such amendments or additional contracts or agreements.

     (c) Prior to the Trigger Date, without the prior written consent or affirmative vote of Helix
(either of which it may withhold in its sole and absolute discretion), Cal Dive shall not, and
shall cause the other members of the Cal Dive Group not to, take certain actions (subject in each
case to certain agreed exceptions) that are prohibited under Helix’s senior secured credit
facility.

     6.6 No Violations.

     (a) Cal Dive acknowledges and agrees that it shall not, and shall cause the other members of
the Cal Dive Group not to, take any action or enter into any commitment or agreement that 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 any member of the Helix Group of: (i) any
provisions of applicable Law; (ii) any provision of the organizational documents of any member of
the Helix Group; (iii) any credit agreement or other material instrument binding upon any member of
the Helix Group; or (iv) any judgment, order or decree of any Governmental Authority having
jurisdiction over any member of the Helix Group or any of its respective assets.

     (b) Helix acknowledges and agrees that it shall not, and shall cause the other members of the
Helix Group not to, take any action or enter into any commitment or agreement that 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 any member of the Cal Dive Group of: (i) any provisions of
applicable Law; (ii) any provision of the organizational documents of Cal Dive; (iii) the Existing
Helix Indebtedness, any credit agreement or any other material instrument binding upon Cal Dive; or
(iv) any judgment, order or decree of any Governmental Authority having jurisdiction over any
member of the Cal Dive Group or any of the Cal Dive Assets.

     (c) Nothing in this Agreement is intended to limit or restrict in any way Helix’s or its
Affiliates’ rights as stockholders of Cal Dive.

-46-

 

     6.7 Registration Statements.

     To the extent necessary to enable the unrestricted transfer of the applicable shares of Cal
Dive Common Stock, upon consummation of the Initial Public Offering, Cal Dive shall file and cause
to remain effective a registration statement with the SEC to register Cal Dive Common Stock that
may be acquired by employees of any member of the Cal Dive Group as contemplated by Helix’s or any
other member of the Helix Group’s employee stock or option plans.

     6.8 Compliance with Charter Provisions.

     Cal Dive shall, and shall cause each of its Subsidiaries to, take any and all actions
necessary to ensure continued compliance by Cal Dive and its Subsidiaries with the provisions of
their certificate or articles of incorporation, bylaws, limited liability company agreement,
partnership agreement or other applicable organizational documents. Cal Dive shall notify Helix in
writing promptly after becoming aware of any act or activity taken or proposed to be taken by Cal
Dive or any of its Subsidiaries or any of their equity holders which resulted or would result in
non-compliance with any such organizational document provisions and, so long as any member of the
Helix Group owns any Cal Dive Capital Stock, Cal Dive shall take or refrain from taking all such
actions as Helix shall in its sole discretion determine necessary or desirable to prevent or remedy
any such non-compliance.

     6.9 Future Intercompany Transactions.

     All proposed intercompany transactions between Cal Dive and Helix after the Closing Date,
including any material amendments to the Transaction Documents, and any consent or approval
proposed to be granted by Cal Dive for Helix’s benefit, in each case that would ordinarily be
submitted for approval by the board of directors of Cal Dive, will be subject to the approval of a
majority of the independent directors (as defined under the applicable rules of any securities
exchange on which shares of Cal Dive Common Stock are listed) of the board of directors of Cal
Dive.

     6.10 [Intentionally Omitted].

     6.11 Helix Policies.

     If a provision of Cal Dive’s Charter or Amended and Restated Bylaws or of any Transaction
Document contradicts a policy of Helix or a member of the Helix Group, (the “Helix
Policies”) that applies to Subsidiaries of Helix, such provision in Cal Dive’s Charter or
Bylaws or Transaction Document shall control. In any other case, and except as otherwise agreed or
unless superseded by any policies adopted by the board of directors of Cal Dive, the Helix Policies
that apply to Subsidiaries of Helix shall apply to Cal Dive and its Subsidiaries until the Trigger
Date.

     6.12 Operations.

     If at any time (a) the number of Vessels utilized by or on behalf of Helix, whether on a
day-rate or otherwise, is below the Utilization Limit, (b) Helix notifies Cal Dive that Helix
wishes to utilize a Vessel, (c) such Vessel is available for the time period requested by Helix and
(d) Helix agrees to pay for the utilization of such Vessel at then prevailing market rates, Cal
Dive shall provide the Vessel to Helix. To exercise such preferential right, Helix must notify Cal
Dive of its need for a Vessel and, if the Vessel is available upon such notice, CDI shall inform
Helix of the corresponding day-rate for such Vessel. Helix shall then have ___(NUMBER) business
days to accept the Vessel (the “Notification Period”). If Helix does not notify Cal Dive of its
decision to utilize the Vessel prior to the expiration of the Notification Period, Helix shall be
deemed to have declined the use of such Vessel for such time, and Cal Dive shall be free to
contract the Vessel to other parties. Such waiver shall not compromise Helix’s ability to exercise
its preferential rights in the future with regard to the utilization of Vessels. As used herein,
“Utilization Limit” means the multiple of the total number of Vessels in Cal Dive’s fleet and
..___, rounded down to the nearest whole number. If the number of Vessels utilized by or on behalf
of Helix, whether on a day-rate or otherwise, is equal to or exceeds the Utilization Limit, then
Helix shall not have the preferential right to utilize any other Vessels, unless and until such
number falls below the Utilization Limit.

     6.13 [Intentionally Omitted].

     6.14 Tax Matters.

     Notwithstanding any provision in this Agreement to the contrary, to the extent that any
representations, warranties, covenants and agreements between Helix and Cal Dive, and their
respective Groups, with respect to Tax matters are set forth in the Tax Matters Agreement,
including indemnification agreements and any tax sharing agreements and arrangements specifically
identified in such agreements, such Tax matters shall be governed exclusively by such Tax
agreements and not by this Agreement.

-48-

 

     6.15 Litigation.

     (a) Subject to Section 3.7, immediately following the execution and delivery of the
Underwriting Agreement by each of the parties thereto, Cal Dive shall, and shall cause the other
members of the Cal Dive Group to assume those Actions relating in any material respect to the Cal
Dive Business in which one or more members of the Helix Group is a defendant or the party against
whom any claim or investigation is directed (collectively, the “Assumed Actions”).

     (b) Subject to Section 3.7, immediately following the execution and delivery of the
Underwriting Agreement by each of the parties thereto, Cal Dive shall, and shall cause the other
members of the Cal Dive Group to, (i) diligently conduct, at its sole cost and expense, the defense
of all Assumed Actions and all Existing Actions, (ii) except as may be provided in Section
6.3, pay all Liabilities that may result from the Assumed Actions and the Existing Actions, and
(iii) pay all fees and costs relating to the defense of the Assumed Actions and the Existing
Actions, including attorneys’ fees and costs incurred after the Closing Date. “Existing
Actions” means those Actions (other than Assumed Actions) in which Cal Dive or any other member
of the Cal Dive Group has been named as a defendant or is the party against whom any claim or
investigation is directed, including those listed on Schedule 6.15(b).

     (c) Notwithstanding anything in this Section 6.15 to the contrary, Helix shall have
the right to participate in the defense of any Assumed Action and to be represented by attorneys of
its own choosing and at its sole cost and expense. In no event shall Cal Dive (or any other member
of the Cal Dive Group) settle or compromise any Assumed Action without the express prior written
consent of Helix unless (i) there is no finding or admission of any violation of any law or any
violation of the rights of any Person by Helix or any other member of the Helix Group, (ii) there
is no relief (either monetary or non-monetary) binding upon Helix or any other member of the Helix
Group, and (iii) neither Helix nor any other member of the Helix Group has any Liability with
respect to any such settlement or compromise.

     (d) Subject to Section 3.7, each of Helix and Cal Dive agrees that at all times from
and after the execution and delivery of the Underwriting Agreement by each of the parties thereto,
if an Action is commenced by a third party naming both parties (or any member of its respective
Group) as defendants thereto and with respect to which one party (or any member of its respective
Group) is a nominal defendant, then the other party shall use commercially reasonable efforts to
cause such nominal defendant to be removed from such Action.

SERVICES AND TERMS

     Section 2.1 Services; Scope.

     (a) During the period commencing on the Closing Date and continuing until the earlier of the
termination of this Agreement or an individual Service pursuant to Section 9.1, subject to
the terms and conditions set forth in this Agreement, each of Helix and Cal Dive as Providers will
provide, or will cause to be provided to the Recipient Group, financial, information technology,
human resources (including, without limitation, training and benefits), operations support,
environmental, health and safety services, legal services, management oversight and other general
services of an administrative and/or advisory nature with respect to the business and operations of
the Helix and Cal Dive Groups, as set forth on Schedule A and Schedule C (the
“Services”), and Cal Dive will, and will cause the other members of the Cal Dive Group to,
and Helix will, and will cause the other members of the Helix Group to, utilize such Services in
the conduct of their respective businesses. The “Services” also will include (1) any Services to
be provided by a Provider to a Recipient as agreed pursuant to Section 10.3(a), and (2) any
Substitute Service; provided, however, that (i) the scope of each Service will be
substantially the same as the scope of such service provided by a Provider to a Recipient on the
last day prior to the Closing in the ordinary course; (ii) the use of each Service by a Recipient
will include use by the Recipient Group’s contractors in substantially the same manner as used by
the contractors of the Recipient Group prior to the Closing; and (iii) nothing in this Agreement
will require that any Service be provided by Helix other than for use in, or in connection with,
the Cal Dive Business, or by Cal Dive other than for use in, or in connection with, the Helix
Business. Nothing in the preceding sentence or elsewhere in this Agreement will be deemed to
restrict or otherwise limit the volume or quantity of any Service; provided, that,
certain volume or quantity changes with respect to a Service may require the parties to negotiate
in good faith and use their commercially reasonable efforts to agree upon a price change with
respect to such Service. If, for any reason, a Provider is unable to provide any Service pursuant
to the terms of this Agreement, such Provider will provide to the Recipient Group a substantially
equivalent service (a “Substitute Service”) at or below the cost for the substituted
Service as set forth on Schedule A or Schedule C, as applicable, and otherwise in
accordance with the terms of this Agreement, including the Standard for Services.

     (b) The Services will include, and the Service Charges reflect charges for, such maintenance,
support, error correction, training, updates and enhancements normally and customarily provided by
members of the Provider Group to other Provider Group members that receive such services. The
Services will include all functions, responsibilities, activities and tasks, and the materials,
documentation, resources, rights and licenses to be used, granted or provided by the Provider Group
that are not specifically described in this Agreement as a part of the Services, but are incidental
to, and would normally be considered an inherent part of, or necessary subpart included within, the
Services or are otherwise necessary for the Provider Group to provide, or the Recipient Group to
receive, the Services.

     (c) This Agreement will not assign any rights to Technology or Intellectual Property between
the parties, other than as specifically set forth herein. Any upgrades, updates or other
modifications to Software or other electronic content made available or delivered to the Cal
Dive

- 4 -

 

Group pursuant to this Agreement will be deemed to be Intellectual Property of the Helix Group
and licensed to the Cal Dive Group, notwithstanding that such upgrades, updates or other
modifications (i) were not used, held for use or contemplated to be used by the Cal Dive Group as
of the Closing Date, (ii) were not controlled by any member of the Helix Group as of the Closing
Date, or (iii) may constitute improvements made after the Closing Date.

     (d) Throughout the term of this Agreement, the Provider and the Recipient of any Service will
cooperate with one another and use their good faith, commercially reasonable efforts to effect the
efficient, timely and seamless provision and receipt of such Service.

     (e) Any Software delivered by a Provider hereunder will be delivered, at the election of the
Provider, either (i) with the assistance of the Provider, through electronic transmission or
downloaded by the Recipient from the applicable intranet, or (ii) by installation by the Provider
on the relevant equipment, with retention by the Provider of all tangible media on which such
Software resides. The Provider and the Recipient acknowledge and agree that no tangible medium
containing such Software (including any enhancements, upgrades or updates) will be transferred to
the Recipient at any time for any reason under the terms of this Agreement, and that the Provider
will, at all times, retain possession and control of any such tangible medium used or consumed by
the Provider in the performance of this Agreement. Each party will comply with all reasonable
security measures implemented by the other party in connection with the delivery of Software.

     Section 2.2 Executive Services.

     Until the earlier of the Trigger Date or termination of this Agreement in accordance with
Section 9.1, in conjunction with the provision of the Services, Helix will make available to Cal
Dive, and Cal Dive will utilize, the management oversight services of the executive officers of
Helix referenced on Schedule A and from time to time as mutually agreed to by the parties, certain
other officers of Helix (collectively, “Helix Executives”); provided, however, that Cal
Dive may terminate the provision of management oversight services by any particular executive
officer of Helix at any time by providing notice of such termination to Helix, such termination to
be effective on the later of the date specified in the notice, if any, or the date that is six
months after delivery of such notice. In rendering such services, until their resignation or the
termination of Services as otherwise provided in this Section 2.2, the General Counsel of Helix
shall serve as the General Counsel of Cal Dive. The obligations of Helix pursuant to this Section
2.2 will be subject to the reasonable demands imposed by, and the reasonable requirements of, the
on-going operations of the Helix Group and the Cal Dive Group, respectively.

     Section 2.3 Performance and Receipt of Services.

     Each of Helix and Cal Dive will, and will cause its respective Groups to, comply with the
following provisions with respect to the Services:

     (a) Each Provider and Recipient will at all times comply with its own then in-force security
guidelines and policies applicable to the performance, access and/or use of the Services and
Information Systems.

     (b) Each Provider and Recipient will take commercially reasonable measures to ensure that no
computer viruses or similar items are coded or introduced into the Services or Information Systems.
If a computer virus is found to have been introduced into the Services or Information Systems, the
parties hereto will use their commercially reasonable efforts to cooperate and to diligently work
together to eliminate the effects of such computer virus.

     (c) Each Provider and Recipient will exercise reasonable care in providing and receiving the
Services to (i) prevent access to the Services or Information Systems by unauthorized Persons, and
(ii) not damage, disrupt or interrupt the Services or Information Systems.

ARTICLE V

COSTS AND DISBURSEMENTS; PAYMENTS

     Section 5.1 Service Charges.

     (a) Schedule A or Schedule C, as applicable, sets forth with respect to each
Service a description of the charges for such Service or the basis for the determination thereof
(the “Service Charges”). Further, in connection with performance of the Services and in
connection with the Undertakings, the Provider will make payments for the benefit of and on behalf
of the Recipient and will incur out-of-pocket costs and expenses (collectively, the “Other
Costs”), which will be reimbursed to the Provider by the Recipient; provided,
that, any Other Costs will only be payable by the Recipient if it receives from the
Provider reasonably detailed data and other documentation sufficient to support the calculation of
amounts due to the Provider as a result of such Other Costs.

     (b) (i) Prior to the Trigger Date, Helix and Cal Dive will arrange for the payment of all
Service Costs and Other Charges in a manner consistent with past practices for similar services
provided by the Helix Group to the Cal Dive Group prior to the date hereof. The Recipient will
have the right to dispute any Service Charges and Other Costs by delivering written notice of such
dispute, setting forth in reasonable detail the basis therefor, to the Provider within, and no
later than, 60 days following the end of the month for which such Service Charge or Other Cost
relates. As soon as practicable after receipt of any such notice, the Provider will provide the
Recipient with reasonably detailed data and documentation sufficient to support the calculation of
any Service Charges and Other Costs that are the subject of the dispute. If the Provider’s
furnishing of such information does not promptly resolve such dispute, the dispute will be resolved
pursuant to Section 8.2.

          (ii) From and after the Trigger Date, the Provider will deliver an invoice to the Recipient on
a monthly basis (or at such other frequency as is set forth on Schedule A or Schedule
C, as applicable) in arrears for the Service Charges and any Other Costs. The Recipient will
pay the amount of such invoice to the Provider in U.S. dollars within 30 days of the date of such
invoice, provided, that, to the extent consistent with past practice with respect
to Services rendered outside the United States, payments may be made in local currency. If the
Recipient fails to pay such amount (excluding any amount contested in good faith) by such date, the
Recipient will be obligated to pay to the Provider, in addition to the amount due, interest on such
amount at the lesser of (i) the three month London Interbank Offered Rate (LIBOR) plus 100 basis
points or (ii) the maximum rate of interest allowed by applicable law, from the date the payment
was due through the date of payment. As soon as practicable after receipt by the Provider of any
reasonable written request by the Recipient, the Provider will provide the Recipient with
reasonably detailed data and documentation sufficient to support the calculation of any amount due
to the Provider under this Agreement for the purpose of verifying the accuracy of such calculation.
If, after reviewing such data and documentation, the Recipient disputes the Provider’s calculation
of any amount due to the Provider, then the dispute will be resolved pursuant to Section
8.2.

- 8 -

 

     Section 5.2 Consents.

     Helix and Cal Dive acknowledge and agree that certain Software and other licenses, consents,
approvals, notices, registrations, recordings, filings and other actions (collectively, “Consents”)
may be required by Helix, Cal Dive or members of their respective Groups in connection with the
provision of the Services. With respect to each Service, the Recipient will, after consultation
with the Provider, either directly pay the out-of-pocket expenses incurred to obtain, perform or
otherwise satisfy each such Consent or after any such Consent is obtained, performed or otherwise
satisfied, reimburse the Provider for all actual, out-of-pocket costs incurred by the Provider and
related to such Consent. Prior to payment of, or reimbursement for, such out-of-pocket expenses,
the Provider will provide the Recipient with an invoice accompanied by reasonably detailed data and
documentation sufficient to evidence the out-of-pocket expenses for which the Provider is seeking
payment or reimbursement. Upon receipt of such invoice and data and documentation, the Recipient
will either pay the amount of such invoice directly in accordance with its general payment terms
with vendors or reimburse the Provider for its payment of the invoice within 30 days of the date of
its receipt of such invoice. If the Recipient disputes the invoiced amount, then the parties will
work together to resolve such dispute. If the parties are unable to resolve such dispute, the
dispute will be resolved pursuant to Section 8.2. Helix and Cal Dive acknowledge and agree
that no prior approval of the Recipient will be required for the Provider to seek any reimbursement
pursuant to this Section 5.2.

ARTICLE VI

STANDARD FOR SERVICE; COMPLIANCE WITH LAWS

     Section 6.1 Standard for Service.

     Except as otherwise provided in this Agreement (including in Schedule A and
Schedule C), Helix and Cal Dive agree that the Provider will perform the Services such that
the nature, quality, standard of care and the service levels at which such Services are performed
are no less than the nature, quality, standard of care and service levels at which the
substantially same services were provided to the members of the Recipient Group by or on behalf of
the Provider on the last day prior to the Closing Date in the ordinary course (the “Standard
for Services”).

     Section 6.2 Compliance with Laws.

     Each of Helix and Cal Dive will be responsible for its, and its respective Group’s, compliance
with any and all Laws applicable to its performance under this Agreement; provided,
however, that each of Helix and Cal Dive will, subject to reimbursement of out-of-pocket
expenses by the requesting party, use commercially reasonable efforts to cooperate and provide the
other party with all reasonably requested assistance (including, without limitation, the execution
of documents and the provision of relevant information) to ensure compliance with all applicable
Laws in connection with any regulatory action, requirement, inquiry or examination related to this
Agreement or the Services.

ARTICLE VII

INDEMNIFICATION; LIMITATION ON LIABILITY

     Section 7.1 Limited Liability of a Provider.

     Notwithstanding the provisions of Section 6.1, no member of a Provider Group, their
respective Affiliates or any of their respective directors, officers or employees, or any of the
heirs, executors, successors or assigns of any of the foregoing (each, a “Provider Indemnified
Party”), will have any liability in contract, tort or otherwise, including for any such party’s
ordinary or contributory negligence, to the Recipient or its Affiliates or Representatives for or
in connection with (i) any Services rendered or to be rendered by any Provider Indemnified Party
pursuant to this Agreement, (ii) the transactions contemplated by this Agreement, or (iii) any
Provider Indemnified Party’s actions or inactions in connection with any such Services or

Party’s (a) gross negligence or willful misconduct, (b) improper use or disclosure of information
of, or regarding, a customer or potential customer of a Recipient Indemnified Party or (c)
violation of applicable Law.

     Section 7.2 Indemnification by Each Provider.

TERMINATION

     Section 9.1 Termination.

     (a) This Agreement may be terminated (1) after the Trigger Date by either Helix or Cal Dive
upon no less than sixty (60) days’ prior written notice; provided, however, after the Trigger Date,
the Provider will continue to provide, and the Recipient will utilize, and will cause the other
members of the Recipient Group to utilize, the Services identified on Schedule C for the
applicable time periods after the Trigger Date set forth in Schedule C, and therefore (A)
the effective date of such termination of this Agreement must be no earlier than the latest date
provided on Schedule C for the provision of Services, (B) the effective date of termination
of individual Services specified on Schedule C must be no earlier than the date provided on
Schedule C for such individual Service, and (C) all other Services that are not specified
on Schedule C will terminate upon the effective termination date provided in such written
notice, or (2) at any time upon mutual agreement of Helix and Cal Dive. Notwithstanding the
foregoing, with respect to specific Services provided hereunder, (i) either party hereto (the
“Non-Breaching Party”) may terminate this Agreement with respect to any individual Service,
in whole but not in part, at any time upon prior written notice by the Non-Breaching Party to the
other party (the “Breaching Party”) if the Breaching Party (including any member of its
respective Group) has failed to perform any of its material obligations under this Agreement
relating to such Service, and such failure will have continued without cure for a period of 60 days
after receipt by the Breaching Party of a written notice of such failure from the Non-Breaching
Party seeking to terminate such Service; provided, however, that no Service may be terminated
pursuant to this clause (i) until the parties have completed the dispute resolution process set
forth in Section 8.2 with respect to such Service; (ii) Helix and Cal Dive may from time to
time mutually agree to terminate any individual Service, in whole but not in part,
provided, that, any such agreement to terminate a Service will comply with
Section 10.10 and include all terms and conditions applicable to termination of the Service
to be terminated and (iii) as provided in Section 2.2, Cal Dive may terminate the provision
of management oversight services by any particular executive officer of Helix at any time by
providing notice of such termination to Helix, such termination to be effective on the later of the
date specified in the notice, if any, or the date that is sixty (60) days after delivery of such
notice. Any such termination of an individual Service will not in any way affect the obligations
of the party terminating such Service to continue to receive all other Services not so terminated
and to continue to provide Services as required by this Agreement.

     (b) In addition to and not in limitation of the rights and obligations set forth in
Section 2.1(d), upon the request of the Recipient of a Service, (i) the Provider of such
Service will cooperate with the Recipient and use its good faith, commercially reasonable efforts
to assist

- 12 -

 

the transition of such Service to the Recipient (or Affiliate of the Recipient or such
third-party vendor designated by the Recipient) by the Service Termination Date for such Service.

     Section 9.2 Effect of Termination.

     Upon termination or expiration of any Service or Undertaking pursuant to this Agreement, the
relevant Provider will have no further obligation to provide the terminated Service or expired
Undertaking, and the relevant Recipient will have no obligation to pay any future Service Charges
or Other Costs relating to any such Service or Undertaking (other than for or in respect of
Services or Undertakings provided in accordance with the terms of this Agreement and received by
such Recipient prior to such termination). Upon termination of this Agreement in accordance with
its terms, no Provider will have any further obligation to provide any Service or Undertaking, and
no Recipient will have any obligation to pay any Service Charges or Other Costs relating to any
Service or Undertaking or make any other payments under this Agreement (other than for or in
respect of Services or Undertakings received by such Recipient prior to such termination).

     Section 9.3 Survival.

     Each of Section 4.1 (Leases), Section 4.2 (Computer-Based Resources),
Article V (Costs and Disbursements), Article VII (Indemnification; Limitation on
Liability), Article VIII (Dispute Resolution), Section 9.2 (Effect of Termination),
this Section 9.3 (Survival), and Article X (General Provisions) will survive the
expiration or other termination of this Agreement and remain in full force and effect.

     Section 9.4 Force Majeure.

     No party hereto (or any member of its Group or any other Person acting on its behalf) will
have any liability or responsibility for failure to fulfill any obligation (other than a payment
obligation) under this Agreement so long as and to the extent to which the fulfillment of such
obligation is prevented, frustrated, hindered or delayed as a consequence of circumstances of Force
Majeure. A party claiming the benefit of this provision will, as soon as reasonably practicable
after the occurrence of any such event: (a) notify the other party of the nature and extent of any
such Force Majeure condition and (b) use commercially reasonable efforts to remove any such causes
and resume performance under this Agreement as soon as feasible.

GENERAL PROVISIONS

     Section 10.1 Independent Contractors.

on the other. All Persons employed by the Provider in the performance of its obligations under
this Agreement will be the sole responsibility of the Provider.

     Section 10.2 Subcontractors.

     Any Provider may hire or engage one or more subcontractors to perform any or all of its

practicable, such additional or other services will be provided on terms substantially similar to
those applicable to Services of similar types and otherwise on terms consistent with those
contained in this Agreement.

     (b) All books, records and data maintained by a Provider for a Recipient with respect to the
provision of a Service will be the exclusive property of such Recipient. The Recipient, at its
sole cost and expense, will have the right to inspect, and make copies of, any such books, records
and data during regular business hours upon reasonable advance notice to the Provider. At the sole
cost and expense of the Provider, upon termination of the provision of any Service, the relevant
books, records and data relating to such terminated Service will be delivered by the Provider to
the Recipient in a mutually agreed upon format to the address of Recipient set forth in Section
10.5 or any other mutually agreed upon location; provided, however, that the
Provider will be entitled to retain one copy of all such books, records and data relating to such
terminated Service for archival purposes and for purposes of responding to any dispute that may
arise with respect thereto.

     If any term or other provision of this Agreement is invalid, illegal or incapable of being
