Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

(i) Merger Agreement:

On July 8, 2019, the Issuer (formerly known as DFB Healthcare Acquisitions Corp.), AdaptHealth Holdings LLC, a Delaware limited liability company (“Adapt”), BM AH Holdings, LLC, a Delaware limited liability company, Access Point Medical, Inc., a Delaware corporation, DFB Merger Sub LLC, a Delaware limited liability company, AH Representative LLC, a Delaware limited liability company, and, solely for the limited purposes set forth therein, BlueMountain Foinaven Master Fund L.P., a Cayman Islands exempted limited partnership, BMSB L.P., a Delaware limited partnership, BlueMountain Fursan Fund L.P., a Cayman Islands exempted limited partnership, and Clifton Bay Investments (collectively, the “Blocker Sellers”), entered into an Agreement and Plan of Merger (the “Agreement”) pursuant to which the Issuer agreed to combine with Adapt in a transaction (the “Transaction”) that would result in Adapt becoming a partially owned subsidiary of the Issuer.  On November 8, 2019, the Transaction closed pursuant to which Clifton Bay Investments and QMI acquired their respective securities of the Issuer under the terms of the Agreement to the extent reported under this Schedule 13D.  All such securities were acquired solely for investment purposes.

CUSIP Nos. 00653Q102; 00653Q110 SCHEDULE 13D

The Merger Agreement provided that, at the Closing, there will be seven members on the Issuer’s board of directors, including, Alan Quasha, together with the other directors named in the Merger Agreement.  Alan Quasha is an affiliate of QMI.

In connection with the Closing, the Issuer changed its name from “DFB Healthcare Acquisitions Corp.” to “AdaptHealth Corp.”

The foregoing description of the Merger Agreement is a summary only and is qualified in its entirety by reference to the Merger Agreement and Amendment No. 1 to the Merger Agreement dated as of October 15, 2019 by and among the parties identified therein, which are filed as Exhibit 2.1 and Exhibit 2.2, respectively, to Form 8-K and are incorporated herein by reference.

(ii) Registration Rights Agreement:

On November 8, 2019, the Issuer entered into a registration rights agreement (the “Registration Rights Agreement”) with Clifton Bay Investments, QMI and the other parties identified therein. The Registration Rights Agreement amended, restated and replaced a prior registration rights agreement pursuant to which the Issuer, among other things, agreed to register for resale (i) shares of Class A Common Stock issuable (a) pursuant to existing contractual obligations or (b) upon the future exercise of private placement warrants or the future exchange of common units representing limited liability company interests in Adapt from and after the Closing pursuant to certain contractual obligations, and (ii) shares of the Issuer’s Class B Common Stock, par value $0.0001 per share, in each case held at the Closing (collectively, “Registrable Securities”).

Pursuant to the Registration Rights Agreement, the Issuer is obligated to file a shelf registration statement registering the resale of all of the Registrable Securities. In addition, subject to certain requirements and customary conditions, the equityholders that are party thereto (the “Equityholders”) may demand, at any time or from time to time, that the Issuer file a registration statement on Form S-1, or any similar long-form registration statement, or if available, on Form S-3 to register the shares of the Class A Common Stock held by the Equityholders. The Registration Rights Agreement also provides the Equityholders with “piggy-back” registration rights, subject to certain requirements and customary conditions. Under certain circumstances, additional payments may be assessed with respect to the shares of Class A Common Stock included in the Registrable Securities in the event that: (i) a resale shelf registration statement has not been declared effective by the Securities and Exchange Commission by the earlier of (a) 60 days following the Issuer’s deadline to file a resale shelf registration statement, or (b) 10 business days after the Securities and Exchange Commission notifies the Issuer that it will not review the resale shelf registration statement, subject to certain potential timing adjustments; or (ii) the resale shelf registration statement is declared effective by the Securities and Exchange Commission but thereafter ceases to be effective prior to the expiration of a designated effective period.

The foregoing description of the Registration Rights Agreement is a summary only and is qualified in its entirety by the terms and conditions of the Registration Rights Agreement, which is filed as Exhibit 4.1 to the Form 8-K and is incorporated herein by reference.

(iii) Lock-Up Agreement

On July 8, 2019, the Issuer entered into a Lock-Up Agreement (the “Lock-Up Agreement”) with Clifton Bay Investments and the other parties identified therein pursuant to which such persons agreed not to sell or enter into certain derivative arrangements with respect to certain equity interests of the Issuer and Adapt for a fixed period of time following the date of Closing.

CUSIP Nos. 00653Q102; 00653Q110 SCHEDULE 13D

The foregoing description of the Lock-Up Agreement is a summary only and is qualified in its entirety by the terms and conditions of the Lock-Up Agreement, a form of which is filed as Annex H to the Proxy Statement and is incorporated herein by reference.

(iv) Indemnification Agreements

Concurrently with the Closing, the Company entered into indemnification agreements with the directors, including Alan Quasha, who is an affiliate of QMI.  Each indemnification agreement provides that, subject to limited exceptions, and among other things, the Issuer will indemnify the director or executive officer to the fullest extent permitted by law for claims arising in his or her capacity as our director or officer.

The foregoing description of the indemnification agreements does not purport to be complete and is qualified in its entirety by the terms and conditions of the indemnification agreement, a form of which is filed as Exhibit 10.4 to this Current Report on Form 8-K and is incorporated herein by reference.

Other than the agreements described above in this Item 6, as of the date hereof, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the Reporting Persons named in Item 2 hereof and between such persons and any person with respect to any securities of the Issuer.
