Safe Harbor Statement
Special Note Regarding Forward-Looking Statements
This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in this
presentation that do not relate to matters of historical fact should be considered forward-looking statements, including without limitation statements with respect to
expectations regarding the timing of discussions with the FDA and/or USDA and approval and licensure of products; development programs, clinical trials and studies,
including without limitation the timing of full enrollment in and the announcement of results of such trials and studies; commercialization and manufacturing of
products, including without limitation establishing larger manufacturing capacities for AT-004 and AT-005; the sufficiency of financial resources; expected future cash
balance and liquidity; licensing initiatives and collaborations; the Company’s plans and opportunities, including without limitation offering a unique portfolio of
innovative therapeutics; and the Company’s belief that its products and product candidates will result in improved outcomes for pets.

These forward-looking statements are based on management’s current expectations. These statements are neither promises nor guarantees, but involve known and
unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future
results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the following: our limited operating
history and expectations of losses for the foreseeable future; our lack of commercial sales; our failure to obtain any necessary additional financing; market conditions
and our ability to raise capital under the shelf registration statement from the sale of our securities; our substantial dependence on the success of certain of our lead
product candidates; our dependence on novel technologies and compliance with complex regulatory requirements; our inability to obtain regulatory approval for our
existing or future product candidates; the lack of commercial success of our current or future product candidates; our inability to realize all of the anticipated benefits
of our acquisitions of Vet Therapeutics and Okapi Sciences; uncertainties regarding the outcomes of studies regarding our products; the uncertainty of outcomes of
the development of pet therapeutics, which is a lengthy and expensive process; effects of competition; our inability to identify, license, develop and commercialize
additional product candidates; our failure to attract and keep senior management and key scientific personnel; our reliance on third-party manufacturers, suppliers,
partners and other third parties which conduct our target animal studies and certain other development efforts; unanticipated difficulties or challenges in the
relatively new field of biologics development and manufacturing; our ability to market our products only for the treatment of indications for which they are approved;
our small commercial organization; difficulties managing the growth of our organization; our significant costs of operating as a public company; risks related to the
restatement of our financial statements for the year ended December 31, 2013 and the identification of a material weakness in our internal control over financial
reporting; changes in distribution channels for pet therapeutics; consolidation of our customers; limitations on our ability to use our net operating carryforwards;
impact of generic products; unanticipated safety or efficacy concerns; our limited patents and patent rights; our failure to comply with our intellectual property license
obligations; our infringement of third party patents and challenges to our patents or rights; litigation resulting from the misuse of our confidential information; the
uncertainty of the regulatory approval process; our failure to comply with regulatory requirements or obtain foreign regulatory approvals; our failure to report
adverse medical events related to our products; legislative or regulatory changes; the volatility of our stock price; our status as an “emerging growth company,” as
defined in the JOBS Act; the potential for dilution if we sell shares of our common stock in future financings; the significant control over our business by our principal
stockholders and management; the potential that a significant portion of our total outstanding shares could be sold into the market in the near future; effects of anti-
takeover provisions in our charter documents and under Delaware law; and our intention not to pay dividends. These and other important factors discussed under the
caption "Risk Factors" in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission, or SEC, on March 16, 2015, along with our
other reports filed with the SEC, could cause actual results to differ materially from those indicated by the forward-looking statements made in this presentation. Any
such forward-looking statements represent management's estimates as of the date of this presentation. While we may elect to update such forward-looking
statements at some point in the future, we disclaim any obligation to do so, even if subsequent events cause our views to change. These forward-looking statements
should not be relied upon as representing our views as of any date subsequent to the date of this presentation.

Atopic Dermatitis

   Medical Need
    Incidence in dogs estimated at up to 10% with recent product launch peak sales
     estimated at $200M
    Chronic condition which often can onset at a young age (1-3 years old)
    Owners can easily diagnose symptoms including itching, sneezing, hair loss, paw
     licking, stains on skin etc.

   Our Solution
    CRTH2 mechanism treats underlying disease rather than symptoms
    Target has been validated in human medicine (asthma, allergic rhinitis and others)
