7.125% Senior Notes due 2021

Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture.

SESI, L.L.C., a Delaware limited liability company (such limited liability company, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Issuer”), promises to pay interest on the principal amount of this Note at the rate of 7.125% per annum, which shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from June 3, 2020. The Issuer shall pay interest on overdue principal at the rate specified herein, and it shall pay interest on overdue installments of interest (including Additional Interest) at the same rate to the extent lawful. Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

The Issuer shall make each interest payment in cash semi-annually in arrears on June 15 and December 15 of each year, commencing on June 15, 2020, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”) to Holders of record of Notes on the immediately preceding June 1 and December 1, provided the record date for the June 15, 2020 Interest Payment Date is June 3, 2020.

By no later than 11:00 a.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Note is due and payable, the Issuer shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium or interest when due. Interest on any Note which is payable, and is timely paid or duly provided for, on any interest payment date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the preceding June 1 and December 1 at the office or agency of the Issuer maintained for such purpose pursuant to Section 2.03 of the Indenture. The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of Paying Agent or Registrar designated by the Issuer maintained for such purpose in the United States or at such other office or agency of the Issuer as may be maintained for such purpose pursuant to Section 2.03 of the Indenture; provided, however, that, at the option of the Issuer, the principal of (and premium, if any) and interest on the Notes may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Notes Register or (ii) wire transfer to an account located in the United States maintained by the payee, subject to the last sentence of this paragraph. Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof.

The Issuer initially appoints The Bank of New York Mellon Trust Company, N.A. as Registrar and Paying Agent for the Notes. The Issuer may change any Registrar or Paying Agent without prior notice to the Holders. The Issuer or any Restricted Subsidiary may act as Paying Agent, Registrar or transfer agent.

The Issuer issued the Notes under an Indenture, dated as of December 6, 2011 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Issuer, the Guarantors and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). The Notes are subject to all terms and provisions of the Indenture, and Holders are referred to the Indenture and the Act for a statement of those terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

The Notes are senior unsecured obligations of the Issuer. The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is unlimited. This Note is one of the 7.125% Senior Notes, Series A, due 2021 referred to in the Indenture. The Notes include (i) $182,060,000 principal amount of the Issuer’s 7.125% Senior Notes, Series A, due 2021 issued under the Indenture on December 6, 2011 (the “Initial Notes”) and (ii) if and when issued, additional 7.125% Senior Notes, Series A, due 2021 or 7.125% Senior Notes, Series B, due 2021 of the Issuer that may be issued from time to time under the Indenture subsequent to December 6, 2011 (the “Additional Notes”) as provided in Section 2.1(a) of the Indenture. The Initial Notes and the Additional Notes shall be considered collectively as a single class for all purposes of the Indenture. The Indenture imposes certain limitations on the incurrence of secured indebtedness and the consummation of mergers and consolidations. The Indenture also imposes requirements with respect to the provision of financial information and the provision of guarantees of the Notes by certain subsidiaries.

To guarantee the due and punctual payment of the principal, premium, if any, and interest (including post-filing or post-petition interest) on the Notes and all other amounts payable by the Issuer under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Guarantors have unconditionally guaranteed (and future guarantors, together with the Guarantors, shall unconditionally Guarantee), jointly and severally, such obligations on a senior unsecured basis pursuant to the terms of the Indenture.

Prior to December 15, 2014, the Issuer may, at its option, upon notice as described under Section 3.03 of the Indenture, on one or more occasions redeem up to 35% of the aggregate principal amount of the Notes issued under the Indenture at a redemption price equal to 107.125% of the aggregate principal amount of the Notes, plus accrued and unpaid interest and Additional Interest, thereon, if any, to but excluding the applicable Redemption Date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, with the net cash proceeds of one or more Public Equity Offerings; provided that (a) at least 65% of the sum of the aggregate principal amount of Notes originally issued under the Indenture on the Issue Date and any Additional Notes that are issued under the Indenture after the Issue Date remains outstanding immediately after the occurrence of each such redemption and (b) each such redemption occurs within 90 days of the date of closing of each such Public Equity Offering.

On and after December 15, 2016, the Issuer may redeem the Notes, in whole or in part, upon notice as described under Section 3.03 of the Indenture, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth in the table below, plus accrued and unpaid interest thereon and Additional Interest, if any, on the Notes redeemed, to but excluding the applicable Redemption Date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the twelve-month period beginning on December 15 of each of the years indicated in the table below:

Any redemption pursuant to this paragraph 6 shall be made pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture.

At any time prior to December 15, 2016, the Issuer may redeem all or a part of the Notes, upon notice as described in Section 3.03 of the Indenture, at a redemption price equal to 100% of the principal amount of Notes redeemed, plus the Applicable Premium (as defined below) as of, and accrued and unpaid interest and Additional Interest, if any, to but excluding the date of redemption (the “Redemption Date”), subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date.

“Applicable Premium” means, as determined by the Issuer, with respect to any Note on any redemption date, the greater of:

(a)

1.0% of the principal amount of the Note; and

the excess of: (a) the present value at such redemption date of (i) the redemption price of the Note at December 15, 2016, (such redemption price being set forth in the table appearing above) plus (ii) all required interest payments due on the Note through December 15, 2016, (excluding accrued but unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over

(b) the then-outstanding principal amount of the Note, if greater.

“Treasury Rate” means, as of any redemption date, the yield to maturity as of such redemption date of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two business days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the redemption date to December 15, 2016; provided, however, that if the period from the redemption date to December 15, 2016, is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

Except as set forth in paragraph 7 below, the Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

If a Change of Control occurs, unless the Issuer has previously or concurrently mailed a redemption notice with respect to all the outstanding Notes as described in Section 3.07 of the Indenture, each Holder shall have the right to require the Issuer to repurchase from each Holder all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to but excluding the date of purchase, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date as provided in, and subject to the terms of, the Indenture.

The Notes shall be issuable only in fully registered form, without coupons, and only in denominations of principal amount of $2,000 and any integral multiple of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any tax and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Note (A) for a period beginning (1) 15 days before the mailing of a notice of an offer to

repurchase or redeem Notes and ending at the close of business on the day of such mailing or (2) 15 days before an interest payment date and ending on such interest payment date or (B) called for redemption or tendered (and not withdrawn) for repurchases in connection with a Change of Control Offer or other tender offer, except the unredeemed or untendered portion of any Note being redeemed or tendered in part.

The registered Holder of this Note may be treated as the owner of it for all purposes.

If money for the payment of principal, premium, if any, or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Issuer at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Issuer for payment as general creditors unless an abandoned property law designates another person and not to the Trustee for payment.

Subject to certain exceptions and conditions set forth in the Indenture, the Issuer at any time may terminate some or all of its obligations under the Notes and the Indenture if the Issuer deposits with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Notes to redemption or maturity, as the case may be.

Subject to certain exceptions contained in the Indenture, the Indenture and the Notes may be amended, or default may be waived, with the consent of the Holders of a majority in principal amount of the outstanding Notes. Without notice to or the consent of any Holder, the Issuer, the Guarantors and the Trustee may amend or supplement the Indenture, any Note Guarantee and the Notes as provided in the Indenture.

If an Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuer or certain Restricted Subsidiaries) occurs and is continuing, the Trustee by notice to the Issuer, or the Holders of at least 25% in principal amount of the total outstanding Notes by notice to the Issuer and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest (including Additional Interest), if any, and any other monetary obligations on all the Notes to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest (including Additional Interest) and any other monetary obligations shall be due and payable immediately. If a bankruptcy, insolvency or reorganization of Superior Energy, the Issuer or certain Restricted Subsidiaries occurs and is continuing, the

principal of, premium, if any, and accrued and unpaid interest (including Additional Interest) and any other monetary obligations on all the Notes shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

Subject to certain limitations set forth in the Indenture, the Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer, Subsidiary Guarantors or their Affiliates with the same rights it would have if it were not Trustee.

An incorporator, director, officer, employee or stockholder of the Issuer or any Subsidiary Guarantor or any of their parent companies, solely by reason of this status, shall not have any liability for any obligations of the Issuer or any Subsidiary Guarantor under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and releases all such liability. The waiver and release are a part of the consideration for the issuance of the Notes.
