Forward-Looking Statements / Risk Factors
This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These
statements include, but are not limited to, our strategy, future operations, future financial position, future revenue, projected costs,
prospects, plans, objectives of management, potential use and effectiveness of our product candidates, expected market growth, the
market opportunity for and the market acceptance of our product candidates, and the strength of our intellectual property portfolio.
Examples of such statements include, but are not limited to, statements relating to the potential clinical risks and efficacy of, and market
opportunities for, our product candidates, including Omadacycline and Sarecycline, the timing of clinical development of, and regulatory
approval for, our product candidates, and the nature and timing of our collaboration agreements with respect to our product candidates.
The words “anticipate,” “estimate,” “expect,” “believe,” “will” and similar terms and phrases are used to identify forward-looking
statements. These statements are based on current information and belief and are not guarantees of future performance. Our ability to
predict results, financial or otherwise, or the actual effect of future plans or strategies is inherently uncertain and actual results may differ
from those predicted depending on a variety of factors. Our operations involve risks and uncertainties, many of which are outside our
control, and any one of which, or a combination of which, could materially affect our results of operations or whether the forward-looking
statements ultimately prove to be correct. We undertake no obligation to publicly update forward-looking statements, whether as a result
of new information, future events or otherwise. Among the risks and uncertainties that could cause actual results to differ materially from
those indicated by such forward-looking statements include delays in clinical trials or unexpected results; the failure of collaborators to
perform obligations under our collaboration agreements; our failure to obtain regulatory approval for our product candidates; our products
not gaining the anticipated acceptance in the marketplace or acceptance being delayed; our products not receiving reimbursement from
healthcare payors; the effects of competition; our inability to protect our intellectual property and proprietary technology through patents
and other means and the risks described in the “Risk Factors” sections of the Registration Statement on Form S-4 (file no 333-198464) and
Paratek’s periodic reports filed with the SEC.

(1)The
table shows combined data from our Phase 2 and Phase 3 non-registration trials, neither of which had a sufficient number of patients
enrolled to determine statistical non-inferiority.
(2)An
Intent-to-Treat, or ITT, population refers to all enrolled subjects, as defined in the protocol, who received at least one dose of study drug.
A Clinically Evaluable, or CE, population refers to all ITT subjects who had a qualifying infection, as defined in the protocol.
(3)Clinical
success refers to the continued improvement or complete resolution of baseline symptoms in the ITT or CE populations, assessed by
the clinical investigator 10 to 17 days after the last dose of study drug.
