Forward Looking Statements This press release contains forward-looking statements as that term is defined in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Statements in this press release that are not purely historical are forward-looking statements. Such forward-looking statements include, among other things, references to novel technologies and methods and our business and product development plans, including the advancement of our proprietary and co- development programs into and through the clinic. Actual results could differ from those projected in any forward-looking statements due to numerous factors. Such factors include, among others, our ability to raise the additional funding we will need to continue to pursue our business and product development plans; the inherent uncertainties associated with developing new products or technologies and operating as a development stage company; our ability to develop, complete clinical trials for, obtain approvals for and commercialize any of our product candidates, including our ability to recruit and enroll patients in our studies; our ability to address the requests of the FDA; competition in the industry in which we operate and market conditions. These forward-looking statements are made as of the date of this press release, and we assume no obligation to update the forward-looking statements, or to update the reasons why actual results could differ from those projected in the forward-looking statements, except as required by law. Investors should consult all of the information set forth herein and should also refer to the risk factor disclosure set forth in the reports and other documents we file with the SEC available at www.sec.gov, including without limitation the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017 and the Company's Quarterly Reports on Form 10-Q. 2
Anticalin Proteins – A Novel Therapeutic Class Features Benefits Derived from lipocalins No observed (human epithelial proteins) immunogenicity to date Engineerable binding pocket Potent target engagement Unique bi/multispecific fusion Engineerable scaffold proteins Enhanced delivery, e.g., Small size (1/8th the size of a mAb) Inhaled therapeutics Our pipeline addresses clinically-validated targets in new ways by leveraging unique features of the Anticalin® protein drug class, effectively taking reduced target biology risk 3

PRS-343: Why did we Design This? HER2-targeting antibody 4-1BB-targeting Anticalin proteins 4-1BB systemically agonizing antibody has shown mono-therapy efficacy yet significant toxicity in the clinic (narrow therapeutic window) PRS-343 preferentially agonizes 4-1BB in the TME by using its anti-HER2 component to drive drug clustering and, therefore, 4-1BB cross-linking 7
PRS-343 Targets Local Biology 4-1BB (CD137) – Key Costimulatory Target T cell costimulation in TME • Marker for tumor-specific T cells in TME • Ameliorates T cell exhaustion • Critical for T cell expansion Tumor-specific • Induces anti-tumor cytolytic activity T cell • Drives central memory T cell differentiation for sustained response Clustering & T cell Activation HER2 – Strongly Validated Tumor Target • Restricted expression on normal tissue High HER2 • Multiple HER2+ tumors with high-unmet need Expression - Bladder, Gastric, Breast and several others - Mediates drug mobilization and immune receptor activation within the tumor bed 8

PRS-343 Shows Bifunctional Activity – Dose-dependent Tumor Growth Inhibition & CD8(+)TIL Expansion in HER2+ Ovarian Cancer Model • PRS-343 shows dose-dependent tumor growth inhibition in HER2-sensitive model • PRS-343 leads to strong and dose-dependent lymphocyte infiltration in tumors; monospecific anti-HER2 mAb (IgG4 backbone) inhibits tumor growth but lacks this immuno-stimulatory activity • Monospecific anti-4-1BB benchmark mAb shows insignificant response compared to isotype control and no significant tumor infiltration of lymphocytes Tumor growth (median) TIL phenotyping by IHC hCD3 hCD4 hCD8 Plot CD3 CD4 CD8 CD45 30 100µg 20 PRS-343 10 Frequency [%] 0 30 CD3 CD4 CD8 CD45 100µg 20 Isotype Ctrl 10 Frequency [%] 0 CD3 CD4 CD8 30 CD45 100µg 20 Incomplete Anti-4-1BB 10 group due to Frequency [%] 0 mortality SK-OV-3 tumor model 12
PRS-343 Avoids Unwanted Effect of Peripheral T Cell Activation, Unlike Systemically Agonistic 4-1BB Antibody • Toxicity observed with anti-4-1BB mAb likely corresponds to indiscriminate peripheral T cell activation • Unlike PRS-343, anti-4-1BB benchmark mAb shows accelerated graft-versus-host-disease with significant mortality in line with literature data1 Survival 100μg PRS-343 100 100μg anti-4-1BB mAb 100μ IgG4 isotype ctrl % CD8+ of CD45+ Survival 50 Percent 0 0 10 20 30 40 1Sanmamed et al., Cancer Res. 2015 Sep 1;75(17):3466-78. 13

PRS-060 for Uncontrolled Asthma: Why did we Design This? What We Know Regeneron/Sanofi’s dupilumab (systemically administered anti-IL-4Ra antibody) has demonstrated the following: Reduction in FeNO Improved lung function Exacerbation Reduction Steroid Sparing 67% 80% reduction in avg. reduction high-eosinophil in corticosteroid patients use What We Are Testing • Is this a local phenomenon? • First-in-man study underway 17
PRS-060 is a Localized IL-4Ra Antagonist for Uncontrolled Asthma • First inhaled Anticalin protein to potently engage the highly validated asthma target, IL-4Ra • Localized target engagement in lung tissue supports a rationale for a convenient, low-dose, low-cost alternative to systemically administered antibodies • Preclinical in vivo PoC for pulmonary delivery at doses supportive of daily administration Lung Total and differential cell counts in OVA model Histopathology hIL-13-induced increases in eotaxin Control 48-hr gene expression P ercentage inhibition of lung inflam m atory cells 6 × 10 06 48hr after OVA challenge 1 .5 Percentage inhibition 78% 71% 79% 66% 5 × 10 06 97% 86% 73% 58% 47% 1 .0 ** 4 × 10 06 × 06 3 10 *** 0 .5 expression 2 × 10 06 *** Cell differential ** ** PRS-060 48-hr *** 06 *** 1 × 10 eotaxin Change in Fold ** 0 .0 * 0 hIL-13 T otal M acrophages Eosinophils Lymphocytes Treat: Veh 50µ g 2µ g 48hr timepoint Pre (hr): 0.5 4 8 24 Anticaln control *p<0.05, **p<0.001 compared with control TLPC134, (TLPC134) ** p<0.01, ***p<0.001 compared to anticalin control, unpaired two-tailed t test (n=9-10); data are Mean± SEM PRS-060 unpaired two-tailed t-test (n=5-6); data are Mean ± SEM Inhibits the influx of key inflammatory cells 24-hr duration of action at doses both in lavage fluid and lung tissue feasible for inhalation 18
