Forward Looking Statements
This presentation includes statements that are, or may be deemed, ‘‘forward-looking statements.’’ In some cases, these forward-looking
statements can be identified by the use of forward-looking terminology, including the terms “believes,” “estimates,” “anticipates,”
“expects,” “plans,” “intends,” “may,” “could,” “might,” “will,” “should,” “approximately” or, in each case, their negative or other variations
thereon or comparable terminology, although not all forward-looking statements contain these words. They appear in a number of
places throughout this presentation and include statements regarding our intentions, beliefs, projections, outlook, analyses or current
expectations concerning, among other things, our ongoing and planned discovery and development of drugs targeting cancer stem
cells, the strength and breadth of our intellectual property, our ongoing and planned preclinical studies and clinical trials, the timing of
and our ability to make regulatory filings and obtain and maintain regulatory approvals for our product candidates, the degree of clinical
utility of our products, particularly in specific patient populations, expectations regarding clinical trial data, our results of operations,
financial condition, liquidity, prospects, growth and strategies, the length of time that we will be able to continue to fund our operating
expenses and capital expenditures, our expected financing needs and sources of financing, the industry in which we operate and the
trends that may affect the industry or us.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics, and
healthcare, regulatory and scientific developments and depend on the economic circumstances that may or may not occur in the future
or may occur on longer or shorter timelines than anticipated. Although we believe that we have a reasonable basis for each forward-
looking statement contained in this presentation, we caution you that forward-looking statements are not guarantees of future
performance and that our actual results of operations, financial condition and liquidity, and the development of the industry in which we
operate may differ materially from the forward-looking statements contained in this presentation as a result of, among other factors, the
factors referenced in the “Risk Factors” section of our Registration Statement on Form S-1, as amended, declared effective by the
Securities and Exchange Commission on July 23, 2013 and our quarterly report on Form 10-Q for the period ended September 30,
2013 (collectively, our “SEC Filings”). In addition, even if our results of operations, financial condition and liquidity, and the development
of the industry in which we operate are consistent with the forward-looking statements contained in this presentation, they may not be
predictive of results or developments in future periods. Any forward-looking statements that we make in this presentation speak only as
of the date of such statement, and we undertake no obligation to update such statements to reflect events or circumstances after the
date of this presentation, except as required by law.

Rationale for Study
l Address unmet need by offering patients access to investigational agents with

there is little approved in 3rd-line and the efficacy of these agents is minimal

Business Development Strategy
Heat’s ImPACT Immunotherapy platform is:
–Differentiated from other allogeneic cell-based approaches
–Extended half life of antigen release, potentially more effective in generating immune
response

1.Clinical Programs (HS-110, HS-410)
• Ideal partner with regional capabilities to fund and expand in EU, Asia, AU
• Heat to retain US commercialization rights (where possible)
2.ImPACT Platform Partnerships
• Use platform for new product discovery funded by partner
• Partner by specific indication(s)
• Clinical development & commercialization by partner in selected territories,
• Heat retaining rest of the world rights
3.MoA complementary with checkpoint inhibitors
• Explore co-development partnerships with anti-PD1 & anti-PDL1 products
