2. Securities Act Exemption Applicable.

Prior to the Effective Date, the Applicants intend to distribute, under the terms and subject to the conditions set forth in the Disclosure Statement for Joint Prepackaged Plan of Reorganization for Weatherford International plc and its Affiliate Debtors under Chapter 11 of the Bankruptcy Code (as may be amended or supplemented, the “Disclosure Statement”) and the accompanying Plan of Reorganization, copies of which will be filed by amendment as Exhibits T3E-1 and T3E-2 to this application, respectively, $1.25 billion of the 2026 Notes to holders of (i) those certain 5.125% senior unsecured notes due 2020, issued by Weatherford Bermuda; (ii) those certain 7.750% senior unsecured notes due 2021, issued by Weatherford Bermuda; (iii) those certain 5.875% exchangeable senior unsecured notes due 2021, issued by Weatherford Bermuda; (iv) those certain 4.500% senior unsecured notes due 2022, issued by Weatherford Bermuda; (v) those certain 8.250% senior unsecured notes due 2023, issued by Weatherford Bermuda; (vi) those certain 9.875% senior unsecured notes due 2024, issued by Weatherford Bermuda; (vii) those certain 6.500% senior unsecured notes due 2036, issued by Weatherford Bermuda; (viii) those certain 7.000% senior unsecured notes due 2038, issued by Weatherford Bermuda; (ix) those certain 9.875% senior unsecured notes due 2039, issued by Weatherford Bermuda; (x) those certain 6.750% senior unsecured notes due 2040, issued by Weatherford Bermuda; (xi) those certain 5.950% senior unsecured notes due 2042, issued by Weatherford Bermuda; (xii) those certain 9.875% senior unsecured notes due 2025, issued by Weatherford Delaware; and (xiii) those certain 6.800% senior unsecured notes due 2037, issued by Weatherford Delaware (collectively, the “Old Notes”).

The 2026 Notes will be issued pursuant to the indentures to be qualified under this application (together, the “Indentures”), copies of which are included herein as Exhibits T3C-1 and T3C-2.

Generally, Section 1145(a)(1) of Title 11 of the United States Code (the “Bankruptcy Code”) exempts an offer and sale of securities under a plan of reorganization from registration under the Securities Act of 1933, as amended (the “Securities Act”), and state securities laws if three principal requirements are satisfied: (i) the securities must be offered and sold under a plan of reorganization and must be securities of the debtor, an affiliate participating in a joint plan of reorganization with the debtor or a successor to the debtor under the plan of reorganization; (ii) the recipients of the securities must hold a claim against, an interest in, or an administrative expense claim against the debtor; and (iii) the securities must be issued entirely in exchange for the recipient’s claim against or interest in the debtor, or principally in such exchange and partly for cash or property.

The Applicants believe that the offer of the 2026 Notes under the solicitation of acceptances for the Plan of Reorganization and the exchange of the Old Notes for the 2026 Notes, together with certain other consideration, under the Plan of Reorganization will satisfy the requirements of Section 1145(a)(1) of the Bankruptcy Code and, therefore, such offer and exchange is exempt from the registration requirements referred to above. To the extent that the solicitation of acceptances of the Plan of Reorganization constitutes an offer of new securities not exempt from registration under Section 1145(a)(1) of the Bankruptcy Code, the Applicants will also rely on Section 4(a)(2) of the Securities Act and, to the extent applicable, Regulation D promulgated thereunder.

The following is a general description of certain provisions of the Indentures, and the description is qualified in its entirety by reference to the forms of Indentures included herein as Exhibits T3C-1 and T3C-2. Capitalized terms used below and not defined herein have the meanings ascribed to them in the Indentures.

(a) Events of Default; Withholding of Notice of Default.

The Indentures contain certain customary events of default, including: (1) default in the payment of any interest when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of the payment is deposited with the trustee or with a paying agent prior to the expiration of the 30-day period), (2) default in the payment of principal at maturity, (3) default in the performance or breach of any other covenant or warranty in the applicable indenture, which default continues uncured for a period of 60 days after (i) receipt of written notice from the trustee or (ii) the applicable Issuer and the trustee receive written notice from the holders of not less than 25% in principal amount of the 2026 Notes as provided in the applicable Indenture, and (4) certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of the applicable Issuer.

If a default occurs and is continuing and is actually known to the Trustee, the Trustee must send to each holder of the 2026 Notes notice of the default within 90 days after it occurs, unless such default shall have been cured or waived before the giving of such notice. Except in the case of certain defaults in payment with respect to any New Note, the Trustee may withhold notice if and so long as it in good faith determines that withholding notice is in the interests of the holders of the 2026 Notes.

(b) Authentication and Delivery of the 2026 Notes; Application of Proceeds.

The 2026 Notes will be signed by one or more officers of the applicable Issuer. No New Note will be entitled to any benefit under the applicable Indenture unless it bears a certificate of authentication executed by the Trustee in manual or facsimile signature. The Trustee may appoint an authenticating agent.

The Issuers will not receive any proceeds from the issuance of the 2026 Notes pursuant to the Plan of Reorganization.

(d) Satisfaction and Discharge.

Each Indenture will be discharged and will cease to be of further effect as to all outstanding 2026 Notes thereunder if (i)(1) all the 2026 Notes thereunder theretofore authenticated and delivered have been delivered to the Trustee for cancellation or (2) all the 2026 Notes thereunder not theretofore delivered to the Trustee for cancellation (a) have become due and payable, (b) will become due and payable at their Stated Maturity within one year or (c) have been called for redemption or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the applicable Issuer and such Issuer has deposited with the Trustee amounts of consideration sufficient to satisfy such Issuer’s obligations under the Indenture and pay all other sums due and payable under the Indenture by such Issuer with respect to the 2026 Notes issued by such Issuer; and (ii) the applicable Issuer has delivered to the Trustee an officers’ certificate and an opinion of counsel stating

9

that all conditions precedent under such Indenture relating to the satisfaction and discharge of such Indenture have been complied with.

(e) Evidence of Compliance with Conditions and Covenants.

Each Issuer is required to deliver to the Trustee within 30 days after such Issuer becomes aware of the occurrence of any event of default or default under the applicable Indenture, written notice setting forth the details of such event of default or default, its status and the action that such Issuer is taking or proposing to take in respect thereto.
