DISCLAIMER This investor presentation (“Investor Presentation”) is for informational purposes only and does not constitute an offer to sell, a solicitation of an offer to buy, or a recommendation to purchase any equity, debt or other financial instruments of Haymaker Acquisition Corp. (“Haymaker”) or OneSpaWorld (“OSW”) or any of OSW or Haymaker’s affiliates’ securities (as such term is defined under the U.S. federal securities laws). This Investor Presentation has been prepared to assist interested parties in making their own evaluation with respect to the proposed business combination of OSW and Haymaker (the “Business Combination”), as contemplated in that certain Business Combination Agreement, dated as of November 1, 2018, as amended from time to time (the “Transaction Agreement”), and for no other purpose. A copy of the Transaction Agreement was attached as Exhibit 2.1 to Haymaker’s Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on November 1, 2018, and a copy of Amendment No. 1 to Business Combination Agreement, dated as of January 7, 2019, was attached as Exhibit 2.1 to Haymaker’s Current Report on Form 8-K filed with the SEC on January 8, 2019. The information contained herein does not purport to be all-inclusive. The data contained herein is derived from various internal and external sources. No representation is made as to the reasonableness of the assumptions made within or the accuracy or completeness of any projections, modeling or any other information contained herein. All levels, prices and spreads are historical and do not represent current market levels, prices or spreads, some or all of which may have changed since the issuance of this document. Any data on past performance, modeling contained herein is not an indication as to future performance. OSW and Haymaker assume no obligation to update the information in this Investor Presentation. Neither OSW nor Haymaker accepts any liability whatsoever for any losses arising from the use of this Investor Presentation or reliance on the information contained herein. Nothing herein shall be deemed to constitute investment, legal, tax, financial, accounting or other advice. This Investor Presentation is being provided for use only by the intended recipient. The information contained herein may not be reproduced or distributed in any format, in whole or in part, without the prior written consent of OSW and Haymaker. The distribution of this Investor Presentation may also be restricted by law and persons into whose possession this Investor Presentation comes should inform themselves about and observe any such restrictions. The recipient acknowledges that it is familiar with the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), and that recipient will neither use, nor cause any third party to use, this Investor Presentation or any information contained herein in contravention of the Exchange Act, including, without limitation, Rule 10b-5 thereunder. No representation or warranty (whether expressed or implied) has been made by Haymaker, OSW or any of their respective affiliates with respect to the matters set forth in this Investor Presentation, and the recipient disclaims any such representation or warranty. Use of Projections This Investor Presentation contains financial forecasts, including with respect to estimated revenues, net income, Adjusted Net Income, EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Unlevered After-Tax Free Cash Flow, Levered After-Tax Free Cash Flow, and Unlevered After-Tax Free Cash Flow Conversion, for OSW fiscal years 2018 to 2020. Neither OSW’s independent auditors, nor the independent registered public accounting firm of Haymaker, audited, reviewed, compiled, or performed any procedures with respect to the projections for the purpose of their inclusion in this Investor Presentation, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this Investor Presentation. These projections should not be relied upon as being necessarily indicative of future results. In this Investor Presentation, certain of the above-mentioned estimated information has been repeated (subject to the qualifications presented herein), for purposes of providing comparisons with historical data. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of OSW, Haymaker or the combined company or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Investor Presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. 1

DISCLAIMER (CONT’D) Forward-Looking Statements This Investor Presentation includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. The expectations, estimates, and projections of the businesses of Haymaker, OSW and OneSpaWorld Holdings Limited (“OSW Holdings”) may differ from their actual results and consequently, you should not rely on these forward looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, expectations with respect to future performance including projected financial information (which is not audited or reviewed by auditors) and anticipated financial impacts of the proposed transaction, the satisfaction of the closing conditions to the proposed transaction, and the timing of the completion of the proposed transaction. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside of the control of Haymaker, OSW and OSW Holdings, and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the Transaction Agreement, (2) the outcome of any legal proceedings that may be instituted against the parties following the announcement of the Transaction Agreement and the transactions contemplated therein; (3) the inability to complete the proposed transaction, including due to failure to obtain approval of the stockholders of Haymaker or other conditions to closing in the Transaction Agreement; (4) the occurrence of any event, change, or other circumstance that could give rise to the termination of the Transaction Agreement or could otherwise cause the transaction to fail to close; (5) the receipt of an unsolicited offer from another party for an alternative business transaction that could interfere with the proposed transaction; (6) the inability to obtain or maintain the listing of the post-acquisition company’s common shares on Nasdaq following the proposed transaction; (7) the risk that the proposed transaction disrupts current plans and operations as a result of the announcement and consummation of the proposed transaction; (8) the ability to recognize the anticipated benefits of the proposed transaction, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably and retain its key employees; (9) costs related to the proposed transaction; (10) changes in applicable laws or regulations; (11) the demand for OSW’s and the combined company’s services together with the possibility that OSW or the combined company may be adversely affected by other economic, business, and/or competitive factors; and (12) other risks and uncertainties included in (x) the “Risk Factors” sections of the most recent Annual Report on Form 10-K filed with the SEC by Haymaker and the Registration Statement on Form S-4 filed with the SEC by OSW Holdings and (y) other documents filed or to be filed with the SEC by Haymaker and OSW Holdings. The foregoing list of factors is not exclusive. You should not place undue reliance upon any forward-looking statements, which speak only as of the date made. Haymaker, OSW, and OSW Holdings 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. Industry and Market Data In this Investor Presentation, OSW relies on and refers to information and statistics regarding market shares in the sectors in which it competes and other industry data. OSW obtained this information and statistics from third-party sources believed to be reliable, including reports by market research firms. OSW has supplemented this information where necessary with information from discussions with its customers and its own internal estimates, taking into account publicly available information about other industry participants and its management’s best view as to information that is not publicly available. Neither OSW nor Haymaker has independently verified the accuracy or completeness of any such third-party information. 2

DISCLAIMER (CONT’D) Use of Non-GAAP Financial Measures This Investor Presentation includes non-GAAP financial measures for OSW which do not conform to SEC Regulation S-X in that it includes financial information (such as EBITDA, Adjusted EBITDA, Adjusted Net Income, Unlevered After-Tax Free Cash Flow, Levered After-Tax Free Cash Flow, and Unlevered After-Tax Free Cash Flow Conversion) not derived in accordance with U.S. GAAP. Accordingly, such information and data is adjusted and presented differently in the preliminary proxy statement/prospectus on Form S-4 initially filed by OSW Holdings on November 13, 2018, as amended from time to time (the “Registration Statement”). OSW believes that the presentation of non-GAAP measures provides information that is useful to investors as it indicates more clearly the ability of OSW to meet capital expenditure and working capital requirements and provides an additional tool for investors to use in evaluating ongoing operating results and trends. You should review OSW’s audited and interim financial statements, which are included in the Registration Statement, and not rely on any single financial measure to evaluate their respective businesses. Other companies may calculate EBITDA, Adjusted EBITDA, Adjusted Net Income, Unlevered After-Tax Free Cash Flow, Levered After-Tax Free Cash Flow, Unlevered After-Tax Free Cash Flow Conversion and other non-GAAP measures differently, and therefore OSW’s respective EBITDA, Adjusted EBITDA, Adjusted Net Income, Unlevered After-Tax Free Cash Flow, Levered After-Tax Free Cash Flow, Unlevered After-Tax Free Cash Flow Conversion and other non-GAAP measures may not be directly comparable to similarly titled measures of other companies. Additional Information On November 13, 2018, OSW Holdings initially filed the Registration Statement with the SEC, and has subsequently filed amendments thereto. The Registration Statement includes a preliminary prospectus with respect to the securities OSW Holdings will issue in connection with the Business Combination and a preliminary proxy statement of Haymaker in connection with the Business Combination. Haymaker will mail a definitive proxy statement/prospectus and other relevant documents to its stockholders. Investors and security holders of Haymaker are advised to read the proxy statement/prospectus in connection with Haymaker’s solicitation of proxies for its special meeting of stockholders to be held to approve the Business Combination (and related matters) because the proxy statement/prospectus will contain important information about the Business Combination and the parties to the Business Combination. The Registration Statement has not yet been declared effective by the SEC. The definitive proxy statement/prospectus will be mailed to stockholders of Haymaker as of a record date to be established for voting on the Business Combination. Stockholders will also be able to obtain copies of the proxy statement/prospectus, without charge, once available, at the SEC’s website at www.sec.gov or by directing a request to: Haymaker Acquisition Corp., 650 Fifth Avenue, Floor 10, New York, New York 10019. This Investor Presentation shall not constitute a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination. Participants in the Solicitation Haymaker, the Seller Representative (as defined in the Transaction Agreement), OSW Holdings, and their respective directors, executive officers, other members of management, and employees, under SEC rules, may be deemed to be participants in the solicitation of proxies of Haymaker’s stockholders in connection with the Business Combination. Investors and security holders may obtain more detailed information regarding the names and interests in the Business Combination of Haymaker’s directors and officers in Haymaker’s filings with the SEC, including Haymaker’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, which was filed with the SEC on March 30, 2018, and the Registration Statement filed by OSW Holdings, which includes the proxy statement of Haymaker for the Business Combination. 3

GROWTH PLAN

UNIQUELY VISIBLE AND PREDICTABLE GROWTH Growth Strategy Built on the Following Key Drivers: 1 . Capture Highly Visible New Ship Growth with Current Cruise Line Partners—Cruise capacity growth is highly visible and predictable, with published global order books reflecting 5+ years of growth—OSW’s ~5-year, fleet-wide contracts entitle it to operate on new ships launched during the contract term—~85% of 2020 maritime revenues from cruise line banners and resorts in OSW’s current contract portfolio 2 . Expand Market Share By Adding New Potential Cruise Line Partners—Room to continue to grow 80% market share in the outsourced maritime health and wellness market as evidenced by recent new contract wins with Celebrity Cruise Lines and others 3 . Continue Launching More Value-Added Services and Products 4 . Focus on Enhancing Health and Wellness Center Productivity—Increase pre-booking and pre-payment capture rate as pre-booked appointments yield ~60% more revenue than services booked onboard—Expand targeted marketing and promotion initiatives—Utilize technology to increase utilization and enhance service mix—Extend retail beyond the ship 5 . Selectively Expand Footprint at Destination Resorts 20
