On October 17, 2025, Nabors Energy Transition Corp.

The Note bears no interest and is due and payable upon the earlier to occur of (i) the date on which the Company consummates its initial business combination and (ii) the liquidation of the Company on or before November 19, 2025, unless such date is extended pursuant to the Company's second amended and restated memorandum and articles of association (the "Amended Articles"), or such later liquidation date as may be approved by the Company's shareholders.

If the Company consummates an initial business combination, it will repay the loan out of the proceeds of the trust account for its public shareholders (the "Trust Account") or, at the option of the Sponsor, convert all or a portion of the loan into warrants for $1.00 per warrant, which warrants will be identical to the warrants issued by the Company in a private placement in connection with the Company's initial public offering. If the Company does not consummate an initial business combination, the Company will repay the loan only from funds held outside of the Trust Account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. **Conversion**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Notwithstanding anything contained in this Note to the contrary, upon receiving due notification by the Maker of the anticipated consummation of an Initial Business Combination, the Payee may elect to convert a portion or all of the unpaid principal balance under this Note into warrants (the "**Conversion Warrants**"). The total Conversion Warrants so issued shall be equal to: (x) the portion of the principal amount of this Note being converted pursuant to this <u>Section 14</u>, divided by (y) the conversion price of One Dollar ($1.00), rounded up to the nearest whole number of warrants. The Conversion Warrants shall be identical to the warrants issued by the Maker in a private placement in connection with the IPO. The Conversion Warrants and their underlying securities, and any other equity security of the Maker issued or issuable with respect to the foregoing by way of a share dividend or share split or in connection with a combination of shares, recapitalization, amalgamation, consolidation or reorganization, shall be entitled to customary registration rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Upon any partial conversion of the principal amount of this Note, (i) such principal amount shall be so converted and such converted portion of this Note shall become fully paid and satisfied, (ii) the Payee shall surrender and deliver this Note, duly endorsed, to the Maker or such other address which the Maker shall designate against delivery of the Conversion Warrants, (iii) the Maker shall promptly deliver a new duly executed Note to the Payee in the principal amount that remains outstanding, if any, after any such conversion and (iv) in exchange for any portion of the surrendered Note, and simultaneous with the surrender of this Note, the Maker shall, at the direction of the Payee, deliver to the Payee (or its members or their respective affiliates) (the Payee, or such other persons, are known herein as the "**Holder**" or "**Holders**") the Conversion Warrants, which shall bear such legends as are required in the opinion of legal counsel to the Maker (or by any other agreement between the Maker and the Payee) and applicable state and federal securities laws, rules and regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Holders shall pay any and all issue and other taxes that may be payable with respect to any issue or delivery of the Conversion Warrants upon conversion of this Note pursuant hereto; <u>provided</u>, <u>however</u>, that the Holders shall not be obligated to pay any transfer taxes resulting from any transfer requested by the Holders in connection with any such conversion.
