ISIN NO0013513606 (as amended from time to time, the “Bond Terms”), the Issuer and the Bond

Trustee are entering into this tap issue addendum (the “Addendum”) in connection with and to

document a Tap Issue under the Bond Terms:

Issuer:	Diversified Gas & Oil Corporation
Bond Trustee:	Nordic Trustee AS
ISIN for the Bonds:	NO0013513606
ISIN for the Temporary Bonds:	NO0013713024
Maximum Issue Amount:	USD 500,000,000
Amount of Additional Bonds:	USD 200,000,000
Amount of Outstanding Bonds after the Tap Issue:	USD 500,000,000
Date of Addendum:	4 February 2026

2.Terms defined in the Bond Terms have, unless expressly defined herein or otherwise required by

the context, the same meaning in this Addendum.

3.This Addendum is a Finance Document and after the date hereof all references to the Bond Terms

in the other Finance Documents shall be construed as references to the Bond Terms as amended

by this Addendum.

4.The Bonds are listed on the Exchange and there is a requirement for a new prospectus in order

for the Additional Bonds to be listed together with such Bonds. The Additional Bonds are

therefore issued under a separate ISIN (such Bonds referred to as the “Temporary Bonds”)

which, upon the approval of the prospectus, will be converted into the ISIN for the Bonds. The

Bond Terms governs such Temporary Bonds. The Issuer will inform the Bond Trustee, the

Exchange and the Paying Agent without undue delay once the prospectus is approved.

Amount of all Bonds outstanding equals the Maximum Issue Amount (less the aggregate Nominal

Amount of previously redeemed Bonds). The provisions of the Bond Terms will apply to any

Additional Bonds.

6.With reference to paragraph (b) of clause 2.3 (Use of proceeds) of the Bond Terms, the Issuer

will use the net proceeds from the issuance of the Additional Bonds for general corporate purposes

of the Group.

7.The issuance of Additional Bonds and disbursement of the Net Proceeds from the Tap Issue to

the Issuer shall be conditional on the Bond Trustee having received in due time (as determined

by the Bond Trustee) prior to the Tap Issue Date each of the following documents, in form and

substance satisfactory to the Bond Trustee:

(i)this Addendum duly executed by all parties hereto;

Exhibit 4.2

(ii)copies of corporate resolutions required for the Tap Issue and any power of attorney or

other authorisation required for the execution of the Addendum and any other Finance

Documents;

(iii)evidence satisfactory to the Bond Trustee that the Issuer meets the Incurrence Test tested

pro forma including the new Financial Indebtedness incurred as a result of issuing such

Additional Bonds;

(iv)any amendment or security and guarantee confirmation required in respect of any Finance

Documents in relation to the Tap Issue;

(v)confirmation that the applicable prospectus requirements (ref the EU prospectus

regulation ((EU) 2017/1129)) concerning the issuance of the Additional Bonds issued

under the Tap Issue have been fulfilled;

(vi)confirmation that the Additional Bonds are registered in the CSD (by obtaining a

Temporary ISIN for the Additional Bonds);

(vii)copies of any written documentation used in marketing the Additional Bonds or made

public by the Issuer or the Manager in connection with the issuance of the Additional

Bonds; and

(viii)legal opinions or other statements as may be required by the Bond Trustee (including in

respect of corporate matters relating to the Issuer and the legality, validity and

enforceability of this Addendum and any other Finance Documents (if applicable)).

The Bond Trustee may (at its sole discretion and in each case) waive or postpone the requirements

for documentation or decide that delivery of certain documents shall be made subject to a

customary closing procedure to be agreed between the Issuer and the Bond Trustee.

8.By its signature to this Addendum, the Issuer confirms that:

(i)no Event of Default under the Bond Terms has occurred or would occur as a result of the

Tap Issue; and

(ii)the representations and warranties contained in clause 7 (Representations and

Warranties) of the Bond Terms are true and correct in all material respects and are

repeated on the date of this Addendum and on the Tap Issue Date.

9.Clause 19 (Governing law and jurisdiction) of the Bond Terms shall apply to this Addendum

mutatis mutandis and as if references in that clause to “these Bond Terms” were to this

Addendum.
