**Item 1.01. Entry into a Material Definitive Agreement.**

The information provided in Item 2.03 of this Current Report on Form 8-K is incorporated by reference into this Item 1.01.

**Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant**

On March 1, 2023, Horizon Acquisition Corporation II (the "**Company**") obtained a working capital loan in the total amount of $275,000 from Flint Rock Portfolio Trust, LLC (the "**Lender**"), an affiliate of the Company's sponsor. The loan made by the Lender is evidenced by a promissory note (the "**Note**"). The Company expects to use the proceeds of the loan to fund working capital deficiencies and to finance transaction costs in connection with the Business Combination (as defined below).

The Note is an unsecured obligation of the Company. It is payable from assets of the Company other than the Company's Trust Account (as defined in the Company's Amended and Restated Memorandum and Articles of Association). The Note provides that the holder waives recourse to the Trust Account.

The principal balance of the Note is payable on the earlier of (i) the date on which the Company consummates its initial business combination and (ii) the date on which the Company liquidates the Trust Account upon the failure of the Company to consummate its initial business combination within the time period set forth in the Company's Amended and Restated Memorandum and Articles of Association. Such time period currently ends on September 30, 2023.

The Note does not bear interest.

The holder of the Note has the option to convert all or any portion of the principal outstanding under such Note into warrants at a conversion price of $1.50 per warrant. However, the maximum principal amount that may be converted, as to the Note and all other notes evidencing working capital loans, is $1,500,000 or such greater dollar amount as may be agreed to by the Company, with such approvals as may be necessary or advisable. The warrants into which the Note may be converted will be substantially identical to the terms of the private placement warrants issued by the Company in connection with its initial public offering. Such terms entitle the holder of a warrant to purchase one Class A ordinary share of the Company for $11.50.

The foregoing description of the Note is qualified in its entirety by reference to the full text of the Note, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

**Additional Information and Where to Find It**

On October 11, 2022, the Company announced the execution of a Business Combination Agreement (the "**BCA**"), dated as of October 11, 2022, among the Company, OTH Merger Sub 1, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Company, Flexjet, Inc., a Delaware corporation ("**Flexjet**"), Flexjet Sub, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Flexjet, and Epic Aero, Inc., a Delaware corporation ("**Epic**"). Epic Fairgrave, Inc., became a party to the BCA by joinder dated February 21, 2023. The BCA provides for the terms and conditions of a proposed business combination transaction with Epic (the "**Business Combination**").

In connection with the BCA, the Company, Epic and Flexjet intend to prepare, and Flexjet intends to file a registration statement on Form S-4 (the "**Registration Statement**") containing a proxy statement/prospectus and certain other related documents, which will be both the proxy statement to be distributed to holders of the Company's ordinary shares in connection with the Company's solicitation of proxies for the vote by the Company's shareholders with respect to the Business Combination and other matters as may be described in the Registration Statement, as well as the prospectus relating to the offer and sale of the securities of Flexjet to be issued in connection with the Business Combination. When available, the Company will mail the definitive proxy statement/prospectus and other relevant documents to its shareholders as of a record date to be established for voting on the Business Combination. This communication is not a substitute for the Registration Statement, the definitive proxy statement/prospectus or any other document that the Company will send to its shareholders in connection with the Business Combination. Investors and security holders of the Company are advised to read, when available, the preliminary proxy statement/prospectus in connection with the Company's solicitation of proxies for its extraordinary general meeting of shareholders to be held to approve the Business Combination (and related matters) and general amendments thereto and the definitive proxy statement/prospectus because the proxy statement/prospectus will contain important information about the Business Combination and the parties to the Business Combination.

Copies of the preliminary proxy statement/prospectus, the definitive proxy statement/prospectus and other documents filed by the Company or Flexjet with the U.S. Securities and Exchange Commission (the "**SEC**") may be obtained, once available, free of charge at the SEC's website at www.sec.gov.

**Participants in the Solicitation**

The Company and its directors, executive officers, other members of management, and employees, under SEC rules, may be deemed to be participants in the solicitation of proxies of the Company's shareholders in connection with the Business Combination. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of the Company's shareholders in connection with the Business Combination will be in the Registration Statement, including a proxy statement/prospectus, when it is filed with the SEC. Investors and security holders may obtain more detailed information regarding the names and interests in the Business Combination of the Company's directors and officers in the Company's filings with the SEC and such information will also be in the Registration Statement to be filed with the SEC, which will include the proxy statement/prospectus of the Company for the Business Combination. These documents can be obtained free of charge at the SEC's website (www.sec.gov).

Flexjet, Epic and their respective directors and executive officers may also be deemed to be participants in the solicitation of proxies from the shareholders of the Company in connection with the Business Combination. A list of the names of such directors and executive officers and information regarding their interests in the proposed business combination will be included in the proxy statement/prospectus for the Business Combination when available.

**Forward-Looking Statements**

Certain statements made in this Current Report and the documents incorporated by reference herein are "forward looking statements" within the meaning of the "safe harbor" provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as: "target," "believe," "expect," "will," "shall," "may," "anticipate," "estimate," "would," "positioned," "future," "forecast," "intend," "plan," "project," "outlook" and other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. Examples of forward-looking statements include, among others, statements made in this Current Report regarding the proposed transactions contemplated by the BCA, including the benefits of the Business Combination, integration plans, expected synergies and revenue opportunities, anticipated future financial and operating performance and results, including estimates for growth, the expected management and governance of the combined company, and the expected timing of the Business Combination.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on the Company's and Epic's managements' current beliefs, expectations and assumptions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Actual results and outcomes may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements.

Important factors that could cause actual results and outcomes to differ materially from those indicated in the forward-looking statements include, among others, the following: (1) the occurrence of any event, change, or other circumstances that could give rise to the termination of the BCA; (2) the outcome of any legal proceedings that may be instituted against the Company, Epic or Flexjet following the announcement of the BCA and the transactions contemplated therein; (3) the inability to complete the proposed Business Combination, including due to failure to obtain approval of the stockholders of the Company and Epic, certain regulatory approvals, or satisfy other conditions to closing in the BCA; (4) the occurrence of any event, change, or other circumstance that could give rise to the termination of the BCA or could otherwise cause the transaction to fail to close; (5) the failure to meet the minimum cash requirement of the BCA due to the Company shareholder redemptions and the failure to obtain replacement financing; (6) the inability to complete a concurrent PIPE investment in connection with the Business Combination; (7) the failure to meet projected development and production targets; (8) the inability to obtain or maintain the listing of Flexjet's shares of common stock on The New York Stock Exchange following the proposed Business Combination; (9) the risk that the proposed Business Combination disrupts current plans and operations as a result of the announcement and consummation of the proposed Business Combination; (10) the ability to recognize the anticipated benefits of the proposed Business Combination, which may be affected by, among other things, competition, the ability of the Company, Epic and Flexjet to each grow and manage growth profitably, and retain its key employees; (11) costs related to the proposed Business Combination; (12) changes in applicable laws or regulations; (13) the possibility that the Company or Epic may be adversely affected by other economic, business, and/or competitive factors; (14) risks relating to the uncertainty of the projected financial information with respect to Epic; (15) risks related to the organic and inorganic growth of Epic's business and the timing of expected business milestones; (16) the amount of redemption requests made by the Company's shareholders; (17) actual or potential conflicts of interest of the Company's shareholders and other related parties as a result of certain relationships and transactions with Flexjet, Epic and the Company, including significant ownership interests and business relationships; (18) members of management of Epic and their affiliated entities and Eldridge and its affiliates (including the Sponsor) will control Flexjet following the consummation of the Business Combination, and their interests may conflict with Flexjet's or its public stockholders, and such persons will be able to determine the composition of Flexjet's board of directors and actions requiring stockholder approval, including a sale of Flexjet (including in an unsolicited transaction, which they will be able to block); and (19) other risks and uncertainties indicated from time to time in the final prospectus of the Company for its initial public offering dated March 15, 2021 filed with the SEC and, when available, the Registration Statement on Form S-4, that will include a definitive proxy statement and final prospectus relating to the proposed Business Combination, including those under "Risk Factors" therein, and in the Company's and Flexjet's other filings with the SEC. The Company cautions that the foregoing list of factors is not exclusive.

The Company, Epic and Flexjet caution readers not to place undue reliance on any forward-looking statements. The Company, Epic and Flexjet do not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in their expectations or any change in events, conditions, or circumstances on which any such statement is based, whether as a result of new information, future events, or otherwise, except as may be required by applicable law. None of the Company, Epic and Flexjet gives any assurance that any of the Company, Epic or Flexjet will achieve its expectations.

**No Offer or Solicitation**

This Current Report is for informational purposes only and is neither an offer to purchase, nor a solicitation of an offer to sell, subscribe for or buy any securities or the solicitation of any vote in any jurisdiction pursuant to the Business Combination or otherwise, nor shall there be any sale, issuance or transfer or securities in any jurisdiction in contravention of applicable law. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act, or an exemption therefrom, and otherwise in accordance with applicable law.

FOR VALUE RECEIVED, Horizon Acquisition Corporation II, a Cayman Islands exempted company (the "**Maker**"), promises to pay to Flint Rock Portfolio Trust, LLC, a Delaware limited liability company, or its registered assigns or successors in interest (the "**Payee**"), the principal sum of $275,000 in lawful money of the United States of America, upon the terms and subject to the conditions set forth below.

Reference is made to the Maker's final prospectus forming a part of its registration statement on Form S-1/A filed with the Securities and Exchange Commission on October 13, 2020 (the "**Prospectus**"). As contemplated by the Prospectus, in order to fund working capital deficiencies or to finance transaction costs in connection with an Initial Business Combination (as defined below), certain persons may, but are not obligated to, loan the Maker funds. The Payee is making a working capital loan in the initial principal amount of this Note. The working capital loans and the notes evidencing them are referred to herein as the "**Working Capital Loans**" and the "**Notes**", respectively.

&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Principal.** Unless this Note has been accelerated upon the occurrence of an Event of Default
(as defined below), the unpaid principal amount shall be payable by the Maker on the earlier of

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the date on which the Maker consummates its initial merger, capital stock exchange, asset acquisition,
stock purchase, reorganization or similar business combination involving the Maker and one or more businesses or entities (the "**Initial Business Combination**") and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date on which the Maker liquidates the Trust Account (as defined below) upon
the failure of the Maker to consummate the Initial Business Combination within the time period set forth in the Mem and Arts (as defined
below).

In addition, the Maker may prepay the principal balance of this Note in whole or in part without premium or penalty.

"**Trust Account**" has the meaning specified in the Mem and Arts.

"**Mem and Arts**" means the Maker's Memorandum and Articles of Association as in effect from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** **No Interest.** No interest shall accrue on the unpaid principal balance of this Note or otherwise.

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Optional Conversion.** The Payee has the right to convert the principal amount of this Note into
Warrants (as defined below) upon the following terms and subject to the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The conversion price shall be $1.50 per Warrant (subject to adjustment or any stock splits, stock dividends,
combinations, reorganizations, recapitalizations and similar events with respect to Class A Shares (as defined below) occurring after
the issue date of this Note). "**Class A Shares**" means the Class A ordinary shares, par value $0.0001 per share, of the
Maker.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Payee must provide written notice to the Maker of its election to convert the principal into Warrants.
The notice must be given not later than the date on which the tally of redemptions of Class A Shares is finalized in connection with the
Initial Business Combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Such conversion shall be effective concurrently with the consummation of the Initial Business Combination,
except as otherwise sequenced to reflect the sequencing of the Initial Business Combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The principal may be converted in whole or in part in integral multiples of $10.00.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The total principal amount converted of all notes evidencing Working Capital Loans may not exceed an amount (the "**Max Amount**") equal to $1,500,000 or such greater dollar amount as may be agreed to by the Maker, with such approvals as may be necessary or advisable. Accordingly, if the total principal amount proposed to be converted by all holders of such notes exceeds the Max Amount, each holder, including the Payee, shall have the right to convert a percentage of the principal amount of the note held by such holder not greater than

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the principal amount of such holder's note divided by (ii) the Max Amount.

"**Warrants**" means warrants that are substantially the same as the Private Placement Warrants issued pursuant to and as defined in the Warrant Agreement between the Maker and Continental Stock Transfer and Trust Company, dated October 22, 2020 (the "**Warrant Agreement**"). Each Warrant shall be exercisable to purchase one Class A Share at $11.50 per share, subject to adjustment as provided in the Warrant Agreement. As used herein, a number of Warrants means warrants to purchase that number of Class A Shares.

Upon conversion as provided above, the principal balance of this Note shall be decreased by the amount so converted (the "**Converted Principal Amount**").

The Maker shall, as soon as practicable after the conversion of this Note in whole or in part, issue and deliver to the Payee a certificate or notice of issuance for the number of Warrants to which the Payee shall be entitled to receive upon such conversion. Upon any conversion of this Note pursuant to this Section 3, the Maker shall be forever released from all of its obligations and liabilities under this Note with respect to the Converted Principal Amount. In the case of a conversion of this Note in full, this Note shall be cancelled and void without further action of the Maker or the Payee. All unpaid principal of this Note that is not converted into Warrants shall continue to remain outstanding and to be subject to the terms and conditions of this Note.

Any Warrants into which this Note is converted will be subject to the terms of the "sponsor support" letter agreement dated as of October 19, 2020 among the Maker and certain other parties thereto.

Each Warrant issuable upon conversion of this Note shall be a "Registrable Security" pursuant to the Registration Rights Agreement dated as of October 22, 2020 among the Maker and certain securityholders of the Maker named therein.

&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Payments.** All payments on this Note shall be made by wire transfer of immediately available
funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by written notice to the Maker.

&nbsp;&nbsp;&nbsp;&nbsp;**5.** **Application of Payments.** All payments by the Maker to the Payee shall be applied first to payment
in full of any costs incurred in the collection of any sum due under this Note, including without limitation reasonable attorney's
fees and expenses, and then to the payment in full of the unpaid principal balance of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;**6.** **Events of Default.** Each of the following shall be an "**Event of Default** ":

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Failure by the Maker to pay the principal amount due pursuant to this Note within five business days
after the date specified in Section 1 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Failure by the Maker to comply with its obligation to convert all or a portion of this Note in accordance
with Section 3 hereof upon exercise of the Payee's conversion right and the continuation of such failure for a period of five business
days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The commencement by the Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization,
rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee,
trustee, custodian, sequestrator (or other similar official) of the Maker or for any substantial part of its property, or the making by
it of any assignment for the benefit of creditors, or the failure of the Maker generally to pay its debts as such debts become due, or
the taking of corporate action by the Maker in furtherance of any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The entry of a decree or order for relief by a court having jurisdiction in the premises in respect
of the Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator,
assignee, custodian, trustee, sequestrator (or similar official) of the Maker or for any substantial part of its property, or ordering
the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60
consecutive days.

&nbsp;&nbsp;&nbsp;&nbsp;**7.** **Remedies.** Upon the occurrence of an Event of Default specified in Section 6(a) or Section 6(b)
hereof, Payee may, by written notice to the Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal
amount of this Note, and all other amounts payable hereunder, shall become immediately due and payable without presentment, demand, protest
or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents evidencing the same
to the contrary notwithstanding.Upon the occurrence of an Event of Default specified in Section 6(c) or Section 6(d) hereof, the unpaid
principal balance of this Note, and all other amounts payable hereunder, shall automatically and immediately become due and payable, in
all cases without any action on the part of Payee.

&nbsp;&nbsp;&nbsp;&nbsp;**8.** **Waivers.** The Maker waives presentment for payment, conversion, demand, notice of dishonor, protest,
and notice of protest with regard to this Note, all errors, defects and imperfections in any proceedings instituted by Payee under the
terms of this Note, and all benefits that might accrue to the Maker by virtue of any present or future laws exempting any property, real
or personal, or any part of the proceeds arising from any sale of any such property,
from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or extension of time
for payment or conversion. The Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof
or any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by Payee.

&nbsp;&nbsp;&nbsp;&nbsp;**9.** **Unconditional Liability.** The Maker hereby waives all notices in connection with the delivery,
acceptance, performance, default, or enforcement of the payment or conversion of this Note, and agrees that its liability shall be unconditional,
without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal,
waiver or modification granted or consented to by Payee, and consents to any and all extensions of time, renewals, waivers or modifications
that may be granted by Payee with respect to the payment or conversion or other provisions of this Note, and agrees that additional makers,
endorsers, guarantors, or sureties may become parties hereto without notice to the Maker or affecting the Maker's liability hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;**10.** **Notices.** Unless expressly provided otherwise herein, all notices, requests, demands, statements
and other communications required or permitted under this Note shall be in writing and shall be delivered personally, sent by registered,
certified or express mail (postage prepaid) or overnight courier service (postage prepaid) or sent by email, in each case as set forth
on Schedule A. A notice shall be deemed given when received. In all cases, delivery of a notice to an addressee
shall be effective whether or not such notice is received by any other person to which a copy of such notice is to be delivered.

&nbsp;&nbsp;&nbsp;&nbsp;**11.** **GOVERNING LAW.** THIS NOTE AND ALL CLAIMS OR CAUSES OF ACTION (WHETHER IN CONTRACT OR TORT) THAT
MAY BE BASED UPON, ARISE OUT OF OR RELATE TO THIS NOTE, OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS NOTE (INCLUDING ANY CLAIM
OR CAUSE OF ACTION BASED UPON, ARISING OUT OF OR RELATED TO ANY REPRESENTATION OR WARRANTY MADE IN OR IN CONNECTION WITH THIS NOTE OR
AS AN INDUCEMENT TO ENTER INTO THIS NOTE), SHALL BE GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK, INCLUDING SECTION 5-1401 OF
THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK, BUT OTHERWISE WITHOUT REFERENCE TO CONFLICT OF LAWS PROVISIONS.

&nbsp;&nbsp;&nbsp;&nbsp;**12.** **Severability.** Any provision contained in this Note which is prohibited or unenforceable in any
