<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law provides that a corporation may indemnify
any person who was or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the fact that he is or
was a director, officer, employee or agent of the corporation, against expenses (including
attorneys&#146; fees), judgments, fines and amounts paid in settlement in connection with such action,
suit or proceeding if such person acted in good faith and in a manner he or she reasonably believed
to be in or not opposed to the best interests of the corporation, and, with respect to any criminal
proceeding, had no reasonable cause to believe his or her conduct was unlawful. A similar standard
of care is applicable in the case of derivative actions, except that indemnification only extends
to expenses (including attorneys&#146; fees) actually and reasonably incurred in connection with defense
or settlement of such an action and court approval is required before there can be any
indemnification where the person seeking indemnification has been found liable to the corporation.
To the extent that a director or officer of a corporation has been successful on the merits or
otherwise in defense of any action referred to above, or in defense of any such action or claim,
issue or matter, that person shall be indemnified against expenses (including attorneys&#146; fees)
actually and reasonably incurred in connection with such action or claim, issue or matter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Bylaws</I>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;VI of Oceaneering&#146;s amended and restated bylaws provides that Oceaneering will
indemnify and hold harmless each of its directors and officers, to the fullest extent applicable
law permits, from and against any and all judgments, penalties, fines (including excise taxes),
amounts paid in settlement and, subject to certain limitations, expenses arising out of any claim,
other than a claim brought by or on behalf of Oceaneering or a related enterprise, by reason of the
fact that: (1)&nbsp;such person is or was a director or an officer of Oceaneering; or (2)&nbsp;while a
director or an officer, such person served, at the request of Oceaneering, as a director, officer,
manager, administrator, employee, agent or representative of a related enterprise (any person
described in item 1 or 2, is referred to as an &#147;Eligible Indemnitee&#148;). For claims brought by or on
behalf of Oceaneering or a related enterprise, Oceaneering will indemnify an Eligible Indemnitee
for all expenses reasonably incurred as a result of such claim if the Eligible Indemnitee is not
adjudged liable under such claim or if the court making the adjudication of liability against the
Eligible Indemnitee determines that despite such an adjudication, the circumstances in the case
warrant that the Eligible Indemnitee be indemnified for expenses reasonably incurred. Article&nbsp;VI
of Oceaneering&#146;s amended and restated bylaws also provides that Oceaneering may advance funds to an
Eligible Indemnitee to cover expenses he or she incurs in defending against any action, suit or
proceeding that may give rise to a right to indemnification upon receipt of an undertaking by or on
behalf of such person to repay such amount if it is ultimately determined that such person is not
entitled to be indemnified by Oceaneering. Oceaneering may, to the extent and in the manner
applicable law permits, indemnify and advance expenses to persons other than present or former
directors or officers of Oceaneering, when authorized by the Board of Directors of Oceaneering or
other appropriate corporate action.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Oceaneering has also entered into indemnification agreements with each of its directors and
executive officers. These indemnification agreements generally provide Oceaneering&#146;s directors and
executive officers with a contractual right of indemnification to the same extent provided by
Section&nbsp;145 of the Delaware General Corporation Law and a contractual right to advancement of
expenses consistent with the provisions of Article&nbsp;VI of Oceaneering&#146;s amended and restated bylaws.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Certificate of Incorporation</I>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Additionally, Oceaneering&#146;s certificate of incorporation, as amended, contains a provision
that eliminates the personal liability of directors to Oceaneering or its stockholders for monetary
damages for breach of the director&#146;s fiduciary duty of care as a director. As a result,
stockholders may be unable to recover monetary damages against directors for negligent or grossly
negligent acts or omissions in violation of their duty of care. The provision does not change the
liability of a director for breach of his duty of loyalty to Oceaneering or to stockholders, for
acts or omissions not in good faith or which involve intentional misconduct or a knowing violation
of law, for the declaration or payment of dividends in violation of Delaware law, or in respect of
any transaction from which that director receives an improper personal benefit.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Oceaneering also maintains directors&#146; and officers&#146; liability insurance for its directors and
officers that protects them from certain losses arising from claims or charges made against them in
their capacities as directors or officers of Oceaneering.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>The Plan</I>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition, Section&nbsp;7.01(E) of the Defined Contribution Prototype Plan and Trust Agreement
relating to the Plan, as amended, provides for indemnification from Oceaneering to members of the
advisory committee, which committee has been designated by Oceaneering as the Plan administrator,
from and against any and all loss resulting from liability to which they may be subjected by reason
of any act or omission (except willful misconduct or gross negligence) in their official capacities
in the administration of the Plan or the related trust (or both); provided that such
indemnification does not relieve any of them from any liabilities under the Employee Retirement
Income Security Act of 1974, as amended, for breach of fiduciary duty.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The discussion of Oceaneering&#146;s Certificate of Incorporation and Bylaws, the Plan and Section
145 of the Delaware General Corporation Law included in this Item&nbsp;6 is intended to be only a

represent a fundamental change in the information set forth in the
Registration Statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range
may be reflected in the form of prospectus filed with the Securities and

employee benefit plan&#146;s annual report pursuant to Section 15(d) of the Exchange Act) that is

permitted to directors, officers and controlling persons of the registrant pursuant to the
foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy as expressed in
the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses incurred or paid by
a director, officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public policy as expressed
in the Securities Act and will be governed by the final adjudication of such issue.

Item 4. Description of Securities.
Not Applicable.
Item 5. Interests of Named Experts and Counsel.
Mr. Haubenreich, who is passing on the legality of the Common Stock offered hereby, as of May
2, 2011 owned approximately 42,250 shares of Common Stock (including 18,000 shares that are
represented by restricted stock units credited under employee benefit plans which are subject to
vesting and settlement).
Item 6. Indemnification of Directors and Officers.
Delaware General Corporation Law
Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify
any person who was or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the fact that he is or
was a director, officer, employee or agent of the corporation, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement in connection with such action,
suit or proceeding if such person acted in good faith and in a manner he or she reasonably believed
to be in or not opposed to the best interests of the corporation, and, with respect to any criminal
proceeding, had no reasonable cause to believe his or her conduct was unlawful. A similar standard
of care is applicable in the case of derivative actions, except that indemnification only extends
to expenses (including attorneys' fees) actually and reasonably incurred in connection with defense
or settlement of such an action and court approval is required before there can be any
indemnification where the person seeking indemnification has been found liable to the corporation.
To the extent that a director or officer of a corporation has been successful on the merits or
otherwise in defense of any action referred to above, or in defense of any such action or claim,
issue or matter, that person shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred in connection with such action or claim, issue or matter.
Bylaws
Article VI of Oceaneering's amended and restated bylaws provides that Oceaneering will
indemnify and hold harmless each of its directors and officers, to the fullest extent applicable
law permits, from and against any and all judgments, penalties, fines (including excise taxes),
amounts paid in settlement and, subject to certain limitations, expenses arising out of any claim,
other than a claim brought by or on behalf of Oceaneering or a related enterprise, by reason of the
fact that: (1) such person is or was a director or an officer of Oceaneering; or (2) while a
director or an officer, such person served, at the request of Oceaneering, as a director, officer,
manager, administrator, employee, agent or representative of a related enterprise (any person
described in item 1 or 2, is referred to as an "Eligible Indemnitee"). For claims brought by or on
behalf of Oceaneering or a related enterprise, Oceaneering will indemnify an Eligible Indemnitee
for all expenses reasonably incurred as a result of such claim if the Eligible Indemnitee is not
adjudged liable under such claim or if the court making the adjudication of liability against the
Eligible Indemnitee determines that despite such an adjudication, the circumstances in the case
warrant that the Eligible Indemnitee be indemnified for expenses reasonably incurred. Article VI
of Oceaneering's amended and restated bylaws also provides that Oceaneering may advance funds to an
Eligible Indemnitee to cover expenses he or she incurs in defending against any action, suit or
proceeding that may give rise to a right to indemnification upon receipt of an undertaking by or on
behalf of such person to repay such amount if it is ultimately determined that such person is not
entitled to be indemnified by Oceaneering. Oceaneering may, to the extent and in the manner
applicable law permits, indemnify and advance expenses to persons other than present or former
directors or officers of Oceaneering, when authorized by the Board of Directors of Oceaneering or
other appropriate corporate action.
Oceaneering has also entered into indemnification agreements with each of its directors and
executive officers. These indemnification agreements generally provide Oceaneering's directors and
executive officers with a contractual right of indemnification to the same extent provided by
Section 145 of the Delaware General Corporation Law and a contractual right to advancement of
expenses consistent with the provisions of Article VI of Oceaneering's amended and restated bylaws.
2
Certificate of Incorporation
Additionally, Oceaneering's certificate of incorporation, as amended, contains a provision
that eliminates the personal liability of directors to Oceaneering or its stockholders for monetary
damages for breach of the director's fiduciary duty of care as a director. As a result,
stockholders may be unable to recover monetary damages against directors for negligent or grossly
negligent acts or omissions in violation of their duty of care. The provision does not change the
liability of a director for breach of his duty of loyalty to Oceaneering or to stockholders, for
acts or omissions not in good faith or which involve intentional misconduct or a knowing violation
of law, for the declaration or payment of dividends in violation of Delaware law, or in respect of
any transaction from which that director receives an improper personal benefit.
Oceaneering also maintains directors' and officers' liability insurance for its directors and
officers that protects them from certain losses arising from claims or charges made against them in
their capacities as directors or officers of Oceaneering.
The Plan
In addition, Section 7.01(E) of the Defined Contribution Prototype Plan and Trust Agreement
relating to the Plan, as amended, provides for indemnification from Oceaneering to members of the
advisory committee, which committee has been designated by Oceaneering as the Plan administrator,
from and against any and all loss resulting from liability to which they may be subjected by reason
of any act or omission (except willful misconduct or gross negligence) in their official capacities
in the administration of the Plan or the related trust (or both); provided that such
indemnification does not relieve any of them from any liabilities under the Employee Retirement
Income Security Act of 1974, as amended, for breach of fiduciary duty.
The discussion of Oceaneering's Certificate of Incorporation and Bylaws, the Plan and Section
145 of the Delaware General Corporation Law included in this Item 6 is intended to be only a
summary and is qualified in its entirety by the full text of each of the foregoing.

Incorporated by reference to the filing indicated.
In lieu of an opinion of counsel concerning compliance with the requirements of the Employee
Retirement Income Security Act of 1974, as amended, and an Internal Revenue Service ("IRS")
determination letter or opinion letter, as applicable, that the Plan is qualified under Section 401
of the Internal Revenue Code of 1986, as amended (the "Code"), the undersigned registrant hereby
undertakes that it has submitted or will submit the Plan and, if expected to affect the qualified
status of the Plan, any amendment thereto to the IRS in a timely
manner and has made or will make all changes required by the IRS in order to qualify the Plan under
Section 401 of the Code.

Item 9. Undertakings.
(a) The undersigned registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:
(i) To include any prospectus required by section 10(a)(3) of the Securities
Act;
(ii) To reflect in the prospectus any facts or events arising after the
effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
Registration Statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range
may be reflected in the form of prospectus filed with the Securities and
Exchange Commission pursuant to Rule 424(b) of the Securities Act if, in the
aggregate, the changes in volume and price represent no more than a 20%
change in the maximum aggregate offering price set forth in the "Calculation
of Registration Fee" table in the effective Registration Statement;
(iii) To include any material information with respect to the plan of
distribution not previously disclosed in the Registration Statement or any
material change to such information in the Registration Statement;
Provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
Registration Statement is on Form S-8, and the information required to be included
in a post-effective amendment by those paragraphs is contained in reports filed with
or furnished to the Securities and Exchange Commission by the registrant pursuant to
section 13 or section 15(d) of the Exchange Act that are incorporated by reference
in the Registration Statement; and
(2) That, for the purpose of determining any liability under the Securities Act, each
such post-effective amendment shall be deemed to be a new registration statement relating to
the securities offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the offering.
(b) The undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the registrant's annual report pursuant to
section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such securities at that
time shall be deemed to be the initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the registrant pursuant to the
foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy as expressed in
the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses incurred or paid by
a director, officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public policy as expressed
in the Securities Act and will be governed by the final adjudication of such issue.
