references herein to the terms “Pricing Disclosure Package” and “Final Offering Memorandum” shall be deemed to refer to and include any information filed under the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), prior to the date hereof and incorporated by reference therein, and any references herein to the terms “amend,” “amendment” or “supplement” with

Offering Memorandum shall be deemed to mean and include all such financial statements and schedules and other information which are incorporated by reference in the Pricing Disclosure Package or Final Offering Memorandum, as the case may be. 

The Initial Purchasers have advised the Issuers that the Initial Purchasers intend, as soon as they deem practicable after this Agreement has
been executed and delivered, to resell (the “Exempt Resales”) the Securities in private sales exempt from registration under the Act on the terms set forth in the Pricing Disclosure Package, solely to (i) persons whom the
Initial Purchasers reasonably believe to be “qualified institutional buyers” (“QIBs”), as defined in Rule 144A under the Act (“Rule 144A”), in accordance with Rule 144A and (ii) other eligible
purchasers pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Act (“Regulation S”) in accordance with Regulations S (the persons specified in clauses (i) and (ii), the

bound or to which any of their assets or properties is subject (collectively, “Agreements and Instruments”), or (C) in violation of any law, statute, rule or regulation or any judgment, order or decree of any domestic or
foreign court or other governmental or regulatory authority, agency or other body with jurisdiction over any of them or any of their assets or properties (“Governmental Authority”), except, other than in the case of clause (A), for
such defaults or violations that would not have, individually or in the aggregate, a Material Adverse Effect. 
 (xiv) The
execution, delivery and performance of the Note Documents and the consummation of the Offering does not and will not (i) violate the charter, bylaws or other organizational documents of the Company or any Subsidiary, (ii) conflict with or
constitute a breach of or a default under (or an event that with notice or the lapse of time, or both, would constitute a default), or require consent under, or result in a Repayment Event (as defined below), or the creation or imposition of a lien,

applicable state securities or “Blue Sky” laws in connection with the purchase and distribution of the Securities by the Initial Purchasers and (B) such consents, which if not obtained, would not, individually or in the
aggregate, have a Material Adverse Effect. No consents or waivers from any other person or entity are required for the execution, delivery and performance of the Note Documents and the consummation of the Offering, other than such consents and
waivers as have been obtained or will be obtained prior to the Closing Date and will be in full force and effect.

United States or to, or for the account or benefit of, U.S. persons except pursuant to an exemption from the registration requirements of the Act. Each Initial Purchaser, severally and not jointly, represents, warrants and covenants to the Issuers
that: 
 (i) Neither it, nor any person acting on its behalf, has or will solicit offers for, or offer or sell, the
Securities by any form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Act, and it has and will
solicit offers for the Securities only from, and will offer and sell the Securities only to, (1) persons whom such Initial Purchaser reasonably believes to be QIBs or, if any such person is buying for one or more institutional accounts for
which such person is acting as fiduciary or agent, only when such person has represented to such Initial Purchaser that each such account is a QIB to whom notice has been given that such sale or delivery is being made in reliance on Rule 144A, and,
in each case, in reliance on the exemption from the registration requirements of the Act pursuant to Rule 144A, or (2) persons other than U.S. persons outside the United States in reliance on, and in compliance with, the exemption from the
registration requirements of the Act provided by Regulation S. 
 (ii) With respect to offers and sales outside the United
States, such Initial Purchaser has offered the Securities and will offer and sell the Securities (1) as part of its distribution at any time and (2) otherwise until 40 days after the later of the commencement of the offering of the
Securities and the Closing Date, only in accordance with Rule 903 of Regulation S or another exemption from the registration requirements of the Act. Accordingly, neither such Initial Purchasers nor any person acting on their behalf has engaged or
will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Securities, and any such persons have complied and will comply with the offering restrictions requirements of Regulation S. Terms used in this
Section 5(b)(ii) have the meanings given to them by Regulation S. 

  
 - 17 - 

 Each Initial Purchaser severally agrees that, at or prior to confirmation of a sale of Securities
pursuant to Regulation S it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it or through it during the restricted period a confirmation or notice to
substantially the following effect: 
 “The Securities covered hereby have not been registered under the United States Securities Act
of 1933, as amended (the “Securities Act”), and may not be offered or sold within the United States or to or for the account or benefit of, U.S. persons (i) as part of their distribution at any time and (ii) otherwise until forty
days after the later of the date upon which the offering of the Securities commenced and the date of closing, except in either case in accordance with Regulation S or Rule 144A under the Securities Act. Terms used above have the meaning given to
them by Regulation S.” 
 The Initial Purchasers understand that the Issuers and, for purposes of the opinions to be delivered to them
pursuant to Section 8 hereof, counsel to the Issuers and counsel to the Initial Purchasers will rely upon the accuracy and truth of the foregoing representations, and each Initial Purchaser hereby consents to such reliance. 

6. Indemnification. 

(a) The Issuers, jointly and severally, agree to indemnify and hold harmless the Initial Purchasers, each person, if any, who
controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, the agents, employees, officers and directors of any Initial Purchaser and the agents, employees, officers and directors of
any such controlling person from and against any and all losses, liabilities, claims, damages and expenses whatsoever (including, but not limited, to reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in
investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all reasonable amounts paid in settlement of any claim or litigation) (collectively, “Losses”) to which they
or any of them may become subject under the Act, the Exchange Act or otherwise insofar as such Losses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the
Pricing Disclosure Package, any Issuer Written Communication (including, but not limited to, any electronic roadshow), the Final Offering Memorandum, or in any amendment or supplement thereto, or arise out of or are based upon the omission or
alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that none of the Issuers will be liable in any such case to the
extent, but only to the extent, that any such Loss arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission relating to an Initial Purchaser made therein in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such Initial Purchaser through the Representatives expressly for use therein. This indemnity agreement will be in addition to any liability that the Issuers may otherwise have,
including, but not limited to, liability under this Agreement. 
 (b) Each Initial Purchaser, severally, and not jointly,
agrees to indemnify and hold harmless the Issuers, and each person, if any, who controls any of the Issuers within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, the agents,

  
 - 18 - 

 
employees, officers and directors of any of the Issuers and the agents, employees, officers and directors of any such controlling person from and against any and all Losses to which they or any
of them may become subject under the Act, the Exchange Act or otherwise insofar as such Losses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the
Pricing Disclosure Package or the Final Offering Memorandum, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that any such Loss arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged
omission relating to such Initial Purchaser made therein in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of such Initial Purchaser through the Representatives expressly for use therein. 

(c) Promptly after receipt by an indemnified party under subsection 6(a) or 6(b) above of notice of the commencement of any
action, suit or proceeding (collectively, an “action”), such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification
is to be sought in writing of the commencement of such action (but the failure so to notify an indemnifying party shall not relieve such indemnifying party from any liability that it may have under this Section 6 except to the extent that it
has been prejudiced in any material respect by such failure and shall not, in any event, relieve such indemnifying party from any liability otherwise than under this Section 6). In case any such action is brought against any indemnified party,
and it notifies an indemnifying party of the commencement of such action, the indemnifying party will be entitled to participate in such action, and to the extent it may elect by written notice delivered to the indemnified party promptly after
receiving the aforesaid notice from such indemnified party, to assume the defense of such action with counsel satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its
or their own counsel in any such action, but the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by the
indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to take charge of the defense of such action within a reasonable time after notice of commencement of the action,
or (iii) the named parties to such action (including any impleaded parties) include such indemnified party and the indemnifying parties (or such indemnifying parties have assumed the defense of such action), and such indemnified party or
parties shall have reasonably concluded that there may be defenses available to it or them that are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the
right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such reasonable fees and expenses of counsel shall be borne by the indemnifying parties. In no event shall the indemnifying parties be
liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for all indemnified parties in connection with any one action or separate but substantially similar or related actions arising in the
same jurisdiction out of the same general allegations or circumstances. An indemnifying party shall not be liable for any settlement of any claim or action effected without its written consent, which

  
 - 19 - 

 
consent may not be unreasonably withheld. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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, unless such settlement (x) includes an unconditional release of such indemnified party from all
liability on claims that are the subject matter of such proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 

7. Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 6 of
this Agreement is for any reason held to be unavailable from the indemnifying party, or is insufficient to hold harmless a party indemnified under Section 6 of this Agreement, each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such aggregate Losses (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers, on the one hand, and the Initial Purchasers, on the other hand, from the
offering of the Securities or (ii) if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Issuers, on the one
hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative benefits received by the Issuers, on the one hand,
and the Initial Purchasers, on the other hand, shall be deemed to be in the same proportion as (x) the total proceeds from the offering of Securities (net of discounts and commissions but before deducting expenses) received by the Issuers are
to (y) the total discount and commissions received by the Initial Purchasers. The relative fault of the Issuers, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by an Issuer or the Initial Purchasers and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission or alleged statement or omission. 
 The Issuers and the
Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations
referred to above. Notwithstanding the provisions of this Section 7, (i) in no case shall any Initial Purchaser be required to contribute any amount in excess of the amount by which the total discount and commissions applicable to the
Securities purchased by such Initial Purchaser pursuant to this Agreement exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged
omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 7, each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each
person, if any, who controls an Issuer within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each director, officer, employee and agent of an Issuer shall have the same rights to contribution as the Issuers.
Any party entitled to contribution will, promptly 

  
 - 20 - 

 
after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made against another party or parties under this Section 7,
notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this
Section 7 or otherwise, except to the extent that it has been prejudiced in any material respect by such failure; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under
Section 6 for purposes of indemnification. Anything in this section to the contrary notwithstanding, no party shall be liable for contribution with respect to any action or claim settled without its written consent; provided, however, that such
written consent was not unreasonably withheld. 
 8. Conditions of Initial Purchasers’ Obligations. The obligations of the
Initial Purchasers to purchase and pay for the Securities, as provided for in this Agreement, shall be subject to satisfaction of the following conditions prior to or concurrently with such purchase: 

(a) All of the representations and warranties of the Issuers contained in this Agreement shall be true and correct on the date
of this Agreement and on the Closing Date. The Issuers shall have performed or complied with all of the agreements and covenants contained in this Agreement and required to be performed or complied with by them at or prior to the Closing Date. The
Initial Purchasers shall have received a certificate, dated the Closing Date, signed by the chief executive officer and chief financial officer of the Company, certifying as to the foregoing and to the effect in Section 8(c). 

(b) The Final Offering Memorandum shall have been printed and copies distributed to the Initial Purchasers as required by
Section 4(b). No stop order suspending the qualification or exemption from qualification of the Securities in any jurisdiction shall have been issued and no proceeding for that purpose shall have been commenced or shall be pending or
threatened. 
 (c) Since the execution of this Agreement, there shall not have been any decrease in the rating of any debt or
preferred stock of the Company or any Subsidiary by any nationally recognized rating organization, or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the
direction of the possible change. 
 (d) The Initial Purchasers shall have received on the Closing Date opinions dated the
Closing Date, addressed to the Initial Purchasers, of (i) Andrews Kurth LLP, counsel to the Company and (ii) Beau M. Thompson, general counsel of the Company, substantially in the form of Exhibits A-1 and A-2 attached hereto. 

(e) The Initial Purchasers shall have received on the Closing Date an opinion dated the Closing Date of Vinson &
Elkins L.L.P., counsel to the Initial Purchasers, in form and substance satisfactory to the Representatives. Such counsel shall have been furnished with such certificates and documents as they may reasonably request to enable them to review or pass
upon the matters referred to in this Section 8 and in order to evidence the accuracy, completeness or satisfaction in all material respects of any of the representations, warranties or conditions contained in this Agreement. 

  
 - 21 - 

 (f) On the date hereof, the Initial Purchasers shall have received “comfort
letters” from each of Ernst & Young LLP and KPMG LLP, the independent public accountants for the Company, dated the date of this Agreement, addressed to the Initial Purchasers and in form and substance satisfactory to the
Representatives and counsel to the Initial Purchasers, covering certain of the financial and accounting information in the Preliminary Offering Memorandum and the Pricing Supplement. In addition, the Initial Purchaser shall have received a
“bring down comfort letter” from Ernst & Young LLP, dated as of the Closing Date, addressed to the Initial Purchasers and addressing the matters in the “comfort letter” delivered on the date hereof pursuant to the
preceding sentence, except that (i) the “bring-down comfort letter” shall cover the financial and accounting information in the Final Offering Memorandum and any amendment or supplement thereto and (ii) procedures shall be
brought down to a date no more than 5 days prior to the Closing Date, and otherwise in form and substance satisfactory to the Initial Purchasers and counsel to the Initial Purchasers. 

(g) The Issuers and the Trustee shall have executed and delivered the Indenture, to which it is a party, and the Initial
Purchasers shall have received copies thereof. 
 (h) The Initial Purchasers shall have been furnished with wiring
instructions for the application of the proceeds of the Securities in accordance with this Agreement and such other information as they may reasonably request. 

(i) All agreements set forth in the blanket representation letter of the Company to DTC relating to the approval of the Notes
by DTC for “book entry” transfer shall have been complied with. 
 If any of the conditions specified in this Section 8 shall
not have been fulfilled when and as required by this Agreement to be fulfilled (or waived by the Initial Purchasers), this Agreement may be terminated by the Initial Purchasers on notice to the Company at any time at or prior to the Closing Date,
and such termination shall be without liability of any party to any other party. 
 The documents required to be delivered by this
Section 8 will be delivered at the office of counsel for the Initial Purchasers on the Closing Date. 
 9. Initial Purchasers
Information. The Company and the Initial Purchasers severally acknowledge that, for all purposes (including Sections 5(a)(i) and 6), the statements set forth in the fifth, fifteenth and eighteenth paragraphs under “Private Placement”
in the Preliminary Offering Memorandum and the Final Offering Memorandum constitute the only information furnished in writing by or behalf of any Initial Purchaser expressly for use in the Pricing Disclosure Package or the Final Offering Memorandum.

 10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements contained in this
Agreement, including the agreements contained in Sections 4(f) and 11(d), the indemnity agreements contained in Section 6 and the contribution agreements contained in Section 7, shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of the Initial Purchasers or any controlling person thereof or by or on behalf of the Company or any controlling person thereof, and shall survive delivery of and payment for the Notes to and by
the Initial Purchasers. The agreements contained in Sections 4(f), 6, 7, 9 and 11(d) shall survive the termination of this Agreement, including pursuant to Section 11. 

  
 - 22 - 

 11. Effective Date of Agreement; Termination. 

(a) This Agreement shall become effective upon execution and delivery of a counterpart hereof by each of the parties hereto.

 (b) The Initial Purchasers shall have the right to terminate this Agreement at any time prior to the Closing Date by
notice to the Company from the Initial Purchasers, without liability (other than with respect to Sections 6 and 7) on the Initial Purchasers’ part to the Company or any affiliate thereof if, on or prior to such date, (i) the Company shall
have failed, refused or been unable to perform any agreement on its part to be performed under this Agreement when and as required; (ii) any other condition to the obligations of the Initial Purchasers under this Agreement to be fulfilled by
the Issuers pursuant to Section 8 is not fulfilled when and as required in any material respect; (iii) trading in any securities of the Company shall be suspended or limited by the Commission or The NASDAQ Global Select Market, or
(iv) trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq Global Select Market shall have been suspended or materially limited, or minimum prices shall have been established thereon by the
Commission, or by such exchange or other regulatory body or governmental authority having jurisdiction; (v) a general moratorium shall have been declared by either Federal, New York State, or Texas State authorities or a material disruption in
commercial banking or securities settlement or clearance services in the United States shall have occurred; (vi) there is an outbreak or escalation of hostilities or national or international calamity in any case involving the United States, on
or after the date of this Agreement, or if there has been a declaration by the United States of a national emergency or war or other national or international calamity or crisis (economic, political, financial or otherwise) which affects the U.S.
and international markets, making it, in the judgment of Deutsche Bank Securities Inc., impracticable to proceed with the offering or delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package; or
(vii) there shall have been such a material adverse change in general economic, political or financial conditions or the effect (or potential effect if the financial markets in the United States have not yet opened) of international conditions
on the financial markets in the United States shall be such as, in the judgment of Deutsche Bank Securities Inc., to make it inadvisable or impracticable to proceed with the offering or delivery of the Securities on the terms and in the manner
contemplated in the Pricing Disclosure Package. 
 (c) Any notice of termination pursuant to this Section 11 shall be
given at the address specified in Section 12 below by telephone or facsimile, confirmed in writing by letter. 
 (d) If
this Agreement shall be terminated pursuant to Section 11(b) (other than solely pursuant to clauses (iv), (v), (vi) or (vii) thereof), or if the sale of the Securities provided for in this Agreement is not consummated because of any
refusal, inability or failure on the part of the Issuers to satisfy any condition to the obligations of the Initial Purchasers set forth in this Agreement to be satisfied or because of any refusal, inability or failure on the part of the Issuers to
perform any agreement in this Agreement or comply with any provision of this 

  
 - 23 - 

 
Agreement, the Issuers, jointly and severally, will reimburse the Initial Purchasers for all of their reasonable out of pocket expenses (including, without limitation, the fees and expenses of
the Initial Purchasers’ counsel) incurred in connection with this Agreement and the transactions contemplated hereby. 

(e) If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by
such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in
the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the
Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial
Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to
purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Company. In the event of a default by any
Initial Purchaser as set forth in this Section 11(e), the Closing Date shall be postponed for such period, not exceeding seven Business Days, as Deutsche Bank Securities Inc. shall determine in order that the required changes in the Final
Offering Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company or any nondefaulting Initial Purchaser for
damages occasioned by its default hereunder. 
 12. Notice. All communications with respect to or under this Agreement, except as may
be otherwise specifically provided in this Agreement, shall be in writing and, if sent to the Initial Purchasers, shall be mailed, delivered or telecopied and confirmed in writing to c/o Deutsche Bank Securities Inc., 60 Wall Street- 44th Floor, New

other indemnified parties referred to in Sections 6 and 7, and their respective successors and assigns, and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this
Agreement or any provision herein contained. The term “successors and assigns” shall not include a purchaser, in its capacity as such, of Notes from the Initial Purchasers.

County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Issuers hereby consent to the jurisdiction of such courts and
personal service with respect thereto. The Issuers hereby waive all right to trial by jury in any proceeding (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Issuers agree that a final
judgment in any such proceeding brought in any such court shall be conclusive and binding upon the Issuers and may be enforced in any other courts in the jurisdiction of which the Issuers are or may be subject, by suit upon such judgment. 

16. Captions. The captions included in this Agreement are included solely for convenience of reference and are not to be considered a

 17. Counterparts. This Agreement may be executed in various counterparts that together shall constitute one
and the same instrument. 
 18. No Fiduciary Relationship. The Issuers hereby acknowledge that the Initial Purchasers are acting
solely as initial purchasers in connection with the purchase and sale of the Securities. The Issuers further acknowledge that each of the Initial Purchasers is acting pursuant to a contractual relationship created solely by this Agreement entered
into on an arm’s length basis and in no event do the parties intend that any Initial Purchaser act or be responsible as a fiduciary to the Issuers, their management, stockholders, creditors or any other person in connection with any activity
that such Initial Purchaser may undertake or has undertaken in furtherance of the purchase and sale of the Securities, either before or after the date hereof. The Initial Purchasers hereby expressly disclaim any fiduciary or similar obligations to
the Issuers, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Issuers hereby confirm their understanding and agreement to that effect. The Issuers and each Initial
Purchaser agree that they are each responsible for making their own independent judgments with respect to any such transactions, and that any opinions or views expressed by any Initial Purchaser to the Issuers regarding such transactions, including
but not limited to any opinions or views with respect to the price or market for the Securities, do not constitute advice or recommendations to the Issuers. The Issuers hereby waive and release, to the fullest extent permitted by law, any claims
that such Issuers may have against the Initial Purchasers with respect to any breach or alleged breach of any fiduciary or similar duty to the Issuers in connection with the transactions contemplated by this Agreement or any matters leading up to
such transactions.

representatives of the Obligors), no facts have come to our attention that have led us to believe that (i) the Disclosure Package (including the Incorporated Documents), as of [        ] p.m. (Eastern
Time) on September [        ], 2013 (which you have informed us is a time prior to the time of the first sale of the Securities by any Initial Purchaser), contained an untrue statement of a material fact or
omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or (ii) the Offering Memorandum (including the Incorporated Documents), as of its
date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made,
not misleading, it being understood that we express no opinion, statement or belief in this letter with respect to (i) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s report
thereon and (ii) any other financial or accounting data, included or incorporated or deemed incorporated by reference in, or excluded from, the Offering Memorandum or the Disclosure Package. 

Without limiting the foregoing, we call to your attention that (i) the Offering Memorandum has been prepared in the context of a Rule
144A transaction and not as part of a registration statement under the Securities Act, and (ii) the Offering Memorandum does not contain all information that would be required in a registration statement under the Securities Act. 

We express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the State of New York, (ii) applicable
laws of the State of Texas, (iii) applicable laws of the United States of America, (iv) certain other specified laws of the United States of America to the extent referred to specifically herein, (v) the DGCL, and (vi) the DLLCA.
References herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents, without our having made any special
investigation as to the applicability of any specific law, rule or 

  
 Exhibit A-1 Page 10 

 
regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references (including without limitation
those appearing in paragraphs 4 and 5 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust, laws, rules or regulations. 

Our opinions expressed herein are subject to the following additional assumptions and qualifications: 

(i) The opinions set forth in paragraph 1 above as to the valid existence and good standing of the Issuer and the other entities mentioned in
such paragraph are based solely upon our review of certificates and other communications from the appropriate public officials. 
 (ii) In
rendering the opinions set forth in paragraph 4 above regarding Applicable Agreements, we do not express any opinion, however, as to any matters dependent on or related to financial ratio or test or any aspect of the financial condition or results
of operation of any of the Obligors. 
 (iii) The opinion set forth in paragraph 7 above with respect to United States federal income tax
consequences is based upon our interpretations of current United States federal income tax law, including court authority and existing final and temporary U.S. Treasury regulations, which are subject to change both prospectively and retroactively,
and upon the assumptions and qualifications discussed herein. We note that such opinion represents merely our best legal judgment on the matters presented and that others may disagree with our conclusion. Such opinion is not binding upon the
Internal Revenue Service or courts, and there is no guarantee that the Internal Revenue Service will not successfully challenge our conclusions. No assurance can be given that future legislative, judicial or administrative changes, on either a
prospective or retroactive basis, would not adversely affect the accuracy of our conclusions. 
 (iv) Treasury Circular 230
Disclosure. This disclosure is provided to comply with Treasury Circular 230. The opinion set forth in paragraph 7 of this letter is not intended or written to be used, and cannot be used, by any person for the purpose of avoiding tax penalties
that may be imposed on the person. Such opinion was written to support the promoting, marketing or recommending of the transactions or matters addressed by this written advice, and the taxpayer should seek advice based on the taxpayer’s
particular circumstances from an independent tax advisor. No limitation has been imposed by our firm on disclosure of the tax treatment or tax structure of the transaction. 

(v) Our opinions in paragraphs 8, 9 and 100 above: 

(1) may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer or other
similar laws relating to or affecting the rights of creditors generally; 
 (2) may be subject to the application of general
principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy and concepts of
materiality, reasonableness, good faith and fair dealing. 

  
 Exhibit A-1 Page 11 

 (vi) We express no opinion as to the validity, effect or enforceability of any provisions: 

(1) purporting to establish evidentiary standards or limitations periods for suits or proceedings to enforce such documents or
otherwise, to establish certain determinations (including determinations of contracting parties and judgments of courts) as conclusive or conclusive absent manifest error, to commit the same to the discretion of any Person or permit any Person to
act in its sole judgment or to waive rights to notice; 
 (2) providing that the assertion or employment of any right or
remedy shall not prevent the concurrent assertion or employment of any other right or remedy, or that each and every remedy shall be cumulative and in addition to every other remedy or that any delay or omission to exercise any right or remedy shall
not impair any other right or remedy or constitute a waiver thereof; 
 (3) relating to severability or separability; 

(4) purporting to limit the liability of, or to exculpate, any Person, including without limitation any provision that purports
to waive liability for violation of securities laws; 
 (5) purporting to waive damages; 

(6) that constitute an agreement to agree in the future on any matter; 

(7) that relate to indemnification, contribution or reimbursement obligations to the extent any such provisions (i) would

(including any federal or state securities law, rule or regulation) or (iii) are determined to be contrary to public policy; 

(8) purporting to establish any obligation of any party as absolute or unconditional regardless of the occurrence or

(10) purporting to require that all amendments, waivers and terminations be in writing or the disregard of any course of
dealing or usage of trade; 

  
 Exhibit A-1 Page 12 

 (11) relating to consent to jurisdiction insofar as such provisions purport to
confer subject matter jurisdiction upon any court that does not have such jurisdiction, whether in respect of bringing suit, enforcement of judgments or otherwise; 

(12) purporting to require disregard of mandatory choice of law principles that could require application of a law other than
the law expressly chosen to govern the instrument in which such provisions appear; 
 (13) purporting to appoint an
attorney-in-fact or relating to powers of attorney; 
 (14) purporting to modify rules of construction; or 

(15) purporting to waive rights to trial by jury or rights to object to jurisdiction based on inconvenient forum. 

(vii) In making our examination of executed documents, we have assumed (except to the extent that we expressly opine above) (1) the valid
existence and good standing of each of the parties thereto, (2) that such parties had the power and authority, corporate, partnership, limited liability company or other, to enter into and to incur and perform all their obligations thereunder,
(3) the due authorization by all requisite action, corporate, partnership, limited liability company or other, and the due execution and delivery by such parties of such documents and (4) to the extent such documents purport to constitute
agreements, that each of such documents constitutes the legal, valid and binding obligation of each party thereto, enforceable against such party in accordance with its terms. In this paragraph (vii), all references to parties to documents shall be
deemed to mean and include each of such parties, and each other person (if any) directly or indirectly acting on its behalf. 
 (viii) Except
to the extent that we expressly opine above, we have assumed that the execution and delivery of the Transaction Documents, and the incurrence and performance of the obligations thereunder of the parties thereto do not and will not contravene,
breach, violate or constitute a default under (with the giving of notice, the passage of time or otherwise) (a) the certificate or articles of incorporation, certificate of formation, charter, bylaws, limited liability company agreement,
limited partnership agreement or similar organic document of any such party, (b) any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument, (c) any statute, law, rule, or regulation, (d) any
judicial or administrative order or decree of any governmental authority, or (e) any consent, approval, license, authorization or validation of, or filing, recording or registration with, any governmental authority, in each case, to which any
party to the Transaction Documents or any of its subsidiaries or any of their respective properties may be subject, or by which any of them may be bound or affected. Further, we have assumed the compliance by each such party, other than the
Obligors, with all laws, rules and regulations applicable to it, as well as the compliance by the each of the Obligors, and each other person (if any) directly or indirectly acting on its behalf, with all laws, rules and regulations that may be
applicable to it by virtue of the particular nature of the business conducted by it or any goods or services produced or rendered by it or property owned, operated or leased by it, or any other facts pertaining specifically to it. In this paragraph
(viii), all references to parties to the Transaction Documents, other than the first such reference, shall be deemed to mean and include each of such parties, and each other person (if any) directly or indirectly acting on its behalf. 

  
 Exhibit A-1 Page 13 

 (ix) Without limiting the generality of our qualification in clause (1) of paragraph
(v) above, we express no opinion as to the applicability or effect of any preference, fraudulent transfer or conveyance, or similar law (including, without limitation, Section 548 of the Bankruptcy Code or Article 10 of the New York Debtor
Creditor Law) on the Transaction Documents or any transactions contemplated thereby or any opinion expressed herein. 
 (x) We express no
opinion as to the effect of the laws of any jurisdiction in which any holder of any Security is located (other than the State of New York) that limit the interest, fees or other charges such holder may impose for the loan or use of money or other
credit. 
 (xi) Except to the extent that we expressly opine above, we have assumed that no authorization, consent or other approval of,
notice to or registration, recording or filing with any governmental authority or regulatory body (other than routine informational filings, filings under the Securities Act and filings under the Securities Exchange Act of 1934, as amended) is
required to authorize, or is required in connection with the transactions contemplated by the Transaction Documents, the execution or delivery thereof by or on behalf of any party thereto or the incurrence or performance by any of the parties
thereto of its obligations thereunder. 
 (xii) We point out that the submission to the jurisdiction of the United States District Court for
the Southern District of New York and the waivers of objection to venue contained in the Indenture cannot supersede a federal court’s discretion in determining whether to transfer an action to another court. 

(xiii) We express no opinion as to provisions of the Transaction Documents to the effect that a guarantor is liable as a primary obligor, and
not as a surety. Furthermore, we advise you that certain of the guaranty and surety waivers contained in the Indenture may be unenforceable in whole or in part. 

(xiv) We have assumed that the sale of Securities pursuant to Regulation S under the Securities Act is not a part of a plan or scheme to evade
the registration provisions of the Securities Act, and furthermore, we have assumed that each of the Initial Purchasers is an “accredited investor” as defined in Rule 501 under the Securities Act. 

This opinion is being furnished only to you in connection with the sale of the Securities under the Purchase Agreement occurring today and is
solely for your benefit and is not to be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by any other Person, including any purchaser of any Security from you and any subsequent purchaser of any Security,
without our express written permission. The opinions expressed herein are as of the date hereof only and are based on laws, orders, contract terms and provisions, and facts as of such date, and we disclaim any obligation to update this opinion
letter after such date or to advise you of changes of facts stated or assumed herein or any subsequent changes in law. 

Very truly yours,

 Exhibit A-2 

FORM OF OPINION OF GENERAL COUNSEL 
 The
opinion of Beau M. Thompson, general counsel for the Company (capitalized terms not otherwise defined herein shall have the meanings provided in the Purchase Agreement, to which this is an Exhibit), to be delivered pursuant to Section 8(d) of
the Purchase Agreement shall be to the effect that: 
 The Company has been duly incorporated under the laws of the State of Delaware and is duly qualified
to do business as a foreign corporation in good standing in all jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to so qualify would not, singularly or in
the aggregate, have a Material Adverse Effect. 
 Each of Cliffs Drilling Company, Cliffs Drilling Trinidad L.L.C., Hercules Drilling Company, LLC, Hercules
Liftboat Company, LLC, Hercules Offshore Liftboat Company LLC, Hercules Offshore Services LLC, THE Offshore Drilling Company, THE Onshore Drilling Company, TODCO Americas Inc., TODCO International Inc., FDT LLC, HERO Holdings, Inc., SD Drilling LLC
and FDT Holdings LLC (collectively, the “Delaware Subsidiaries”) has been duly organized and is an existing corporation or limited liability company, as applicable, in good standing under the laws of the State of Delaware, with corporate
or limited liability company power and authority, as applicable, to own its properties and conduct its business as described in the Pricing Disclosure Package; and each Delaware Subsidiary is duly qualified to do business as a foreign corporation or
limited liability company, as applicable, in good standing in each of the jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to so qualify or have such power
or authority would not, singularly or in the aggregate, have a Material Adverse Effect; all of the issued and outstanding equity interests of each Delaware Subsidiary have been duly authorized and validly issued in accordance with the organizational
documents of such Subsidiary and the Delaware General Corporate Law or the Delaware LLC Act, as applicable, and are fully paid (to the extent required under the applicable Delaware Subsidiary’s organizational documents) and nonassessable
(except as such nonassessability may be affected by Section 18-607 of the Delaware LLC Act), and the equity interests of each Delaware Subsidiary are owned by the Company, directly or through Subsidiaries, free from liens, encumbrances, defects
or adverse claims (a) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the Company or one of its Subsidiaries as debtor is on file as of a recent date in the office of the Secretary of
State of the State of Delaware or (b) otherwise known to such counsel, without independent investigation, in each case other than liens, encumbrances and adverse claims created by or arising under the Delaware General Corporate Law, the
Delaware LLC Act, the organizational documents of such Delaware Subsidiary, the Indenture or the Credit Agreement. 
 Except as disclosed in the Pricing
Disclosure Package, there are no contracts, agreements or understandings known to such counsel between the Issuer and any other person granting such person the right to require the Issuer to file a registration statement under the Act with respect
to any securities of the Issuer owned or to be owned by such person or to require the Issuer to include such securities in the securities registered pursuant to any other registration statement filed by the Issuer under the Act that have not been
validly waived or satisfied prior to the Closing Date. 

  
 Exhibit A-2 Page 1 

 Except as disclosed in the Pricing Disclosure Package, to the knowledge of such counsel (i) there are no
legal or governmental proceedings by or before any court or governmental agency, authority or body to which the Company or any of its subsidiaries is a party or to which any of their respective properties is subject of a character required to be
described in the Pricing Disclosure Package (if this offering were registered under the Securities Act) which are not described as required, and (ii) there are no contracts or documents of a character required to be described in the Pricing
Disclosure Package (if this offering were registered under the Securities Act) or to be filed as exhibits to the Company’s reports that have been filed with the SEC and are incorporated by reference in the Pricing Disclosure Package or the
Offering Memorandum (the “Incorporated Documents”) which are not described or filed as required. 
 The statements under the caption
“Description of other indebtedness” in the Pricing Disclosure Package and the Offering Memorandum, insofar as such statements purport to summarize certain provisions of documents referred to therein, fairly summarize such provisions in all
material respects, subject to the qualifications and assumptions stated therein. 
 I have participated in conferences with officers and other
representatives of the Company, the independent registered public accounting firm for the Issuers, with representatives of Company counsel and with representatives of and counsel for the Initial Purchasers, at which the contents of the Pricing
Disclosure Package and the Offering Memorandum, including each of the Incorporated Documents, and related matters were discussed, and although I did not independently verify such information, and am not passing upon and do not assume any
responsibility for, the accuracy, completeness or fairness of the statements contained in the Pricing Disclosure Package and the Offering Memorandum, on the basis of the foregoing, no facts have come to my attention that lead me to believe that that
the Pricing Disclosure Package, as of the pricing date, or that the Offering Memorandum, as of its date or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary
in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that I have not been requested to and do not make any comment with respect to the financial statements and
related schedules, including the notes and schedules thereto and the auditors’ report thereon and any other financial or accounting data included in, or excluded from, the Pricing Disclosure Package or the Offering Memorandum).

 We expect that delivery of the notes will be made against payment therefor on or about the closing date specified on the
cover page of this offering memorandum, which will be the tenth business day following the date of pricing of the notes (this settlement cycle being referred to as “T+10”). Under Rule 15c6-1 of the U.S. Securities and Exchange Commission
under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing or the
next succeeding six business days will be required, by virtue of the fact that the notes initially will settle in T+10, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their
own advisor.
