Merger
Agreement

”), by and among Petra, Petra Acquisition Merger Inc., a Delaware corporation and wholly-owned Subsidiary
of Petra (“

Merger Sub

”), and Revelation Biosciences, Inc., a

In accordance with the terms

Effective Time

”),
each share of Revelation’s common stock, Series A Preferred Stock, and Series A-1 Preferred Stock issued and outstanding immediately
prior to the Effective Time shall be cancelled and shall be converted into the right to receive the Per Share Merger Consideration (i.e.,
the portion of the Merger Consideration Shares with respect to a single share of Revelation’s common stock, Series A Preferred Stock
or Series A-1 Preferred Stock, as the case may be, equal, in each case, to the quotient obtained by dividing (x) the Merger Consideration
Shares by (y) the Fully Diluted Company Shares).  As used herein, “

Fully Diluted Company Shares

” means
the

sum

, without duplication, of (a) all shares of Revelation’s common stock that are issued and outstanding immediately
prior to the Effective Time;

In addition, pursuant to the
Merger Agreement, at the Effective Time, each Revelation RSU Award (as defined in the Merger Agreement) that is outstanding as of immediately
prior to the Effective Time shall be assumed by Petra and shall be converted into that number of whole Parent RSU Awards (as defined in
the Merger Agreement) equal to the product (rounded down to the nearest whole number) of: (i) the number of Revelation RSU Awards held
by that holder as of immediately prior to the Effective Time; multiplied by (ii) the Common Stock Exchange Ratio (as defined in the Merger
Agreement) (a “

Parent RSU Award

” and collectively, the “

Parent RSU Awards

”). 
Further, each Revelation Warrant (as defined in the Merger Agreement) shall be converted into a warrant to purchase, subject to substantially
the same terms and conditions as were applicable under such Revelation Warrant, the number of shares of Petra Common Stock (rounded down
to the nearest whole share), determined by multiplying the number of shares of Revelation common stock subject to such Revelation Warrant
immediately prior to the Effective Time by the Common Stock Exchange Ratio, at an exercise price per share of Petra Common Stock (rounded
up to the nearest whole cent) equal to (x) the exercise price per share of Revelation common stock of such Revelation Warrant divided
by (y) the Common Stock Exchange Ratio (a “

Converted Warrant

” and collectively, the “

Converted Warrants

”)).

Forward-Looking Statements


 


This Current Report on Form
8-K and the documents incorporated by reference herein (this “

Current Report

”) contain certain “forward-looking
statements” within the meaning of “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995,
as amended. 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” 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 Merger Agreement,
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 Petra’s and Revelation’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 an amendment or termination
of the Merger Agreement and the proposed transaction contemplated thereby; (2) the inability to complete the transactions contemplated
by the Merger Agreement due to the failure to obtain approval of the stockholders of Petra or Revelation or other conditions to closing
in the Merger Agreement; (3) the inability to project with any certainty the amount of cash proceeds remaining in the Petra trust account
at the closing of the transaction; (4) the uncertainty relative to the cash made available to Revelation at the closing should any material
redemption requests be made by the Petra stockholders (since the sources of cash projected assume that no redemptions will be requested
by Petra stockholders); (5) the inability of the post-closing company to obtain or maintain the listing of its securities on Nasdaq following
the business combination; (6) the amount of costs related to the business combination; (7) Revelation’s ability to yield sufficient
cash proceeds from the transaction to support its short-term operations and research and development efforts since the Merger Agreement
requires no minimum level of funding in the trust fund to close the transaction; (8) the outcome of any legal proceedings that may be
instituted against the parties following the announcement of the business combination; changes in applicable laws or regulations; (9)
the ability of Revelation to meet its post-closing financial and strategic goals, due to, among other things, competition; (10) the ability
of the company post-closing to grow and manage growth profitability and retain its key employees; (11) the possibility that the company
post-closing may be adversely affected by other economic, business, and/or competitive factors; risks relating to the successful development
of Revelation’s product candidates; (12) the clinical utility of an increase in intranasal IP-10 levels as a treatment for viral
infections; the ability to complete planned clinical studies of REVTx-99; (13) expected initiation of the clinical studies, the timing
of clinical data; (14) the outcome of the clinical data, including whether the results of such study is positive or whether it can be
replicated; (15) the outcome of data collected, including whether the results of such data and/or correlation can be replicated; (16)
the timing, costs, conduct and outcome of our other clinical studies; (17) the anticipated treatment of future clinical data by the FDA,
the EMA or other regulatory authorities, including whether such data will be sufficient for approval; (18) the success of future development
activities for REVTx-99 and expanded indications, REVTx-200, REVDx-501, or any other product candidates; (19) potential indications for
which product candidates may be developed; (20) the potential impact that COVID-19 may have on Revelation’s suppliers, vendors,
regulatory agencies, employees and the global economy as a whole; (21) the expected duration over which Revelation’s balances will
fund its operations; (22) and other risks and uncertainties described herein, as well as those risks and uncertainties indicated from
time to time in the final prospectus of Petra for its initial public offering dated October 7, 2020 filed with the SEC and the proxy statement
on Schedule 14A relating to the proposed business combination, including those under “Risk Factors” therein, and in Petra’s
other filings with the SEC. Petra cautions that the foregoing list of factors is not exclusive. Petra and Revelation caution readers not
to place undue reliance upon any forward-looking statements, which speak only as of the date made. Petra and Revelation 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 its their expectations or any change in events, conditions, or circumstances on which any such statement is based.
