 **Cautionary Statement Regarding Forward-Looking Statements**

Certain statements herein and the documents incorporated herein by reference may constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act, and Rule 175 promulgated thereunder, and Section 21E of the Exchange Act, and Rule 3b-6 promulgated thereunder, which statements involve inherent risks and uncertainties.

Examples of forward-looking statements include, but are not limited to, statements with respect to the expectations, hopes, beliefs, intentions, plans, prospects, financial results of strategies regarding Haymaker, Suncrete, PubCo, the Business Combination and statements regarding the anticipated benefits and timing of the completion of the proposed Business Combination and PIPE investment, plans and use of proceeds, objectives of management for future operations of Suncrete, expected operating costs of Suncrete and its subsidiaries, the upside potential and opportunity for investors, Suncrete's plan for value creation and strategic advantages, market site and growth opportunities, Suncrete's acquisition strategy, regulatory conditions, competitive position and the interest of other corporations in similar business strategies, technological and market trends, future financial condition and performance and expected financial impacts of the Business Combination, the satisfaction of closing conditions to the Business Combination and the PIPE investment and the level of redemptions of Haymaker's public shareholders, and PubCo's, Suncrete's and Haymaker's expectations, intentions, strategies, assumptions or beliefs about future events, results at operations or performance or that do not solely relate to historical or current facts. These forward-looking statements generally are identified by the words "believe," "project," "expect," "anticipate," "estimate," "intend," "strategy," "future," "opportunity," "potential," "plan," "may," "should," "will," "would," "will be," "will continue," "will likely result," and similar expressions. Forward-looking statements are based on assumptions as of the time they are made and are subject to risks, uncertainties and other factors that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results expressed or implied by such forward-looking statements. Such risks, uncertainties and assumptions, include, but are not limited to:

· the risk that the Business Combination and the PIPE investment
may not be completed in a timely manner or at all;

· the failure by the parties to satisfy the conditions to the
consummation of the PIPE investment and the Business Combination, including the approval of Haymaker's shareholders;

· the failure to realize the anticipated benefits of the Business
Combination;

· the outcome of any potential legal proceedings that may be instituted
against PubCo, Suncrete, Haymaker or others following announcement of the Business Combination;

· the level of redemptions of Haymaker's public shareholders
which may reduce the public float of, reduce the liquidity of the trading market of, and/or maintain the quotation, listing, or trading
of the Class A ordinary shares of Haymaker or the PubCo Class A Common Stock;

· the failure of PubCo to obtain or maintain the listing of its
securities on any stock exchange on which the PubCo Class A Common Stock will be listed after closing of the Business Combination;

· costs related to the Business Combination and as a result of
PubCo becoming a public company;

· changes in business, market, financial, political and regulatory
conditions;

· risks relating to Suncrete's anticipated operations and
business, including the success of any future acquisitions;

· the risk that issuances of equity or debt securities following
the closing of the Business Combination, including issuances of equity securities in connection with Suncrete's acquisition strategy,
may adversely affect the value of Suncrete's common stock and dilute its stockholders;

· the risk that after consummation of the Business Combination,
PubCo experiences difficulties managing its growth and expanding operations;

· challenges in implementing the business plan, due to lack of
an operating history, operational challenges, significant competition and regulation; and

· those risk factors discussed in documents of PubCo, Haymaker
or Suncrete filed, or to be filed, with the SEC.

The foregoing list of risk factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the "Risk Factors" section Haymaker's Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and the Registration Statement and proxy statement/prospectus filed by PubCo and Suncrete, and other documents filed or to be filed by PubCo, Haymaker and Suncrete from time to time with the SEC. These filings do or will identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. There may be additional risks that none of PubCo, Suncrete or Haymaker presently know or currently believe are immaterial that could also cause actual results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and none of the parties or any of their representatives assumes any obligation or intends to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. None of the parties or any of their representatives gives any assurance that PubCo, Suncrete or Haymaker will achieve its expectations.
