Purchase Agreement

On July 17, 2018, the Issuers and the Initial Guarantors (as defined below) entered into a purchase agreement (the “Purchase Agreement”) with Citigroup Global Markets Inc., as representative (the “Representative”) of the several initial purchasers named therein (the “Initial Purchasers”), in connection with an offering (the “Notes Offering”) by the Issuer of $400.0 million aggregate principal amount of 6.00% senior notes due 2026 (the “2026 Notes”). The 2026 Notes will be guaranteed on a senior unsecured basis by the Company, Magnolia Oil & Gas Parent LLC, Magnolia Oil & Gas Intermediate LLC (the “Initial Guarantors”) and certain other domestic subsidiaries that guarantee other indebtedness of the Issuers and the guarantors. The Issuers expect the net proceeds from the Notes Offering to be approximately $386.3 million, after deducting estimated fees and expenses.

The closing of the Notes Offering is expected to occur on July 31, 2018 and is conditioned upon the satisfaction or waiver of all conditions to the closing of the Company’s business combination with EnerVest, Ltd.’s South Texas Division (the “business combination”) and customary closing conditions. The Issuers intend to use the net proceeds of the Notes Offering to fund the cash consideration payable in connection with the business combination and for general corporate purposes.

The 2026 Notes are being issued and sold to the Initial Purchasers pursuant to an exemption from the registration requirements of the Securities Act, pursuant to Section 4(a)(2) thereunder. The Initial Purchasers intend to resell the 2026 Notes only to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to certain persons outside the United States in accordance with Regulation S under the Securities Act. The 2026 Notes have not been registered under the Securities Act or applicable state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.

The Purchase Agreement contains customary representations, warranties and agreements by the Company and the Issuer and customary conditions to closing, obligations of the parties and termination provisions. Additionally, the Company and the Issuer have agreed to indemnify the Initial Purchasers against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the Initial Purchasers may be required to make because of any of those liabilities. Furthermore, the Issuers have agreed with the Initial Purchasers not to offer or sell any debt securities issued or guaranteed by the Issuers for a period of 90 days after the date of the Purchase Agreement without the prior written consent of the Representative.

Relationships

The Initial Purchasers and their respective affiliates have in the past performed commercial banking, investment banking and advisory services for the Issuers and their affiliates from time to time for which they have received customary fees and reimbursement of expenses and may, from time to time, engage in transactions with and perform services for the Issuers and their affiliates in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses. In the ordinary course of their various business activities, the Initial Purchasers and their respective affiliates may make or hold a broad array of investments and actively trade debt and
