1 Source: Gartner, August 2018. Excludes portion of the entire $124 billion market attributable to service fees and hardware/in fra structure security. 2019 President’s federal budget for cyber is $15bln, though there is additional undisclosed funding. 2019 budget increased 14% since 2017 82% percent of states report that cybersecurity is a high priority but only 13% rate themselves as proficient. -- FEMA 2017 Report Elevated ambition and resources of cyber attackers Emergence of cyberattacks as a tool of warfare Heightened awareness of extreme costs of breach Deepening and comprehensive dependency on computing $45 Bln Information Security Market Sizing 1 Large Market for InfoSec: US Government is Greater Than 33% 5

Even with the best end - to - end encryption, messaging and data communications have critical vulnerabilities and are disruptable ● Sender/recipient metadata (IP, location, identity) is exposed, breaching privacy ● Discoverability of sender and recipient identities makes them targets of attack ● Even sophisticated metadata obfuscation techniques have a signature; hackers can find and block such traffic Problem: Public Network Communications Are Vulnerable U.S. military, intelligence, emergency response, etc. do not have software security solutions for this. Human lives and $ billions are at stake Note: More on the metadata problem here from EFF . 6

● Our customizable solution helps the sender and recipient “Hide in Plain Sight” ○ Protocol with multi - layer transport encryption for intelligent routing (inspired by TOR), protecting user identity / geolocation ○ Front - end SDKs/apps with hardware - based encryption for cross - platform secure and ephemeral comms ○ Payload camouflage evades deep packet inspection / service blocking ● Progress & traction: $8.4MM in revenues in 2018/19 from foundational client ○ Early version of protocol deployed with a customer January 2019 ○ Late stages of dev/testing on use case extensions We May Have the Only In - Market Solution for Communications Network Anonymity Three Levels of Comms Security: ● Content (the message is protected) ● Metadata (the sender and recipient ID is protected) ● Network (the transmission is indistinguishable from other internet traffic) 7

Most Competitors Focus Only on Content Protection 8 Competitive Company Content Level Metadata Level Network Level Blackberry * Koolspan * Signal Silent Circle * Telegram WhatsApp Telos Ghost * Wickr * Wire SecureCo * ● Most government procurement is via large prime contractors (e.g., Raytheon, General Dynamics) ● Most technology provided by prime contractors is subcontracted to smaller companies. Secure comms providers below span consumer, enterprise and government * Has a government - focused product offering (that we are aware of)

Intelligent Routing and Encryption for Communications and Data Transport ● Secure end - to - end encryption assures confidentiality ● Multi - layer transport encryption based on onion routing ● Intelligent routing similar to TOR hidden services protects end - point/user identity and geolocation 9 PeerStream Products Address Communications Security Gaps Front - end complement to PSP for cross platform secure end - user communications ● Ephemeral communications ● Developing hardware - based encryption and carrier - level identity attestation 1 ● Capability for compliance and audit options to meet regulatory requirements 1. Hardware encryption via partnership with Rivetz. Carrier identity attestation through partnership with Telefonica.

Use Cases: First - Best Applications for Government Critical Infrastructure Data Communications System/IoT and human communications, alerts and control mechanisms for infrastructure can be hardened against bad actors seeking disruption and ransom attacks. Law Enforcement Guard sensitive communication on active investigations and logistical coordination to avoid confidentiality breaches and interference, and as warranted, protect the identity of investigators. Emergency Management Decentralized and encrypted routing of critical communications provides protection from disruption and interference from bad actors so that crisis management comms are reliably available. Military / Intelligence Protection of metadata (e.g., IP address, geo - location, identity) for low - profile, secure and anonymous comms for field operatives and intelligence assets . Operates on consumer - grade devices/networks: inexpensive and inconspicuous. 10

Strong Traction in Federal Government Sales & BD 11 ● Sales pipeline of 70+ targets, of which approximately 85% are government opportunities ● Pipeline includes >$60MM of potential annual recurring revenue 1 ● Direct - to - government sales prioritized where target has budgetary autonomy; otherwise seeking access through prime contractors ● High percentage uptake in sourcing leads (nearly 100%). Negligible attrition once in the sales funnel, though long timelines ● We presently have only one full - time sales/BD role; have not yet addressed the enterprise market 1. Represents revenue potential if PeerStream converted all pipeline prospects to paying clients at the expected revenues bas ed on contemplated service levels and pricing. No assurance can be given that PeerStream will convert all or any pipeline prospects into paying customers, or at what value.

We Expect to Broaden to Enterprise Customer Targets As Well Multi - year contracts with recurring licensing revenue, plus service revenue for installation, customization, support and training Military / Intelligence CIA, NSA, Military Special Ops, Army S&T, Navy, Marines, DARPA Emergency Management FEMA, first responders, alert systems, interdepartmental comms Law Enforcement DOJ/FBI, State & Large Metro Police, CBP, ICE Critical Infrastructure Data Comms Power grid, fuel & water supply, voting, transportation (e.g., air traffic control) Telecom Terrestrial/satellite carrier comms security.

Non - GAAP Financial Measures Adjusted EBITDA is defined as net income (loss) adjusted to exclude net income (loss) from discontinued operations, gain on s ale of dating applications, interest income, net, income tax benefit (expense) from continuing operations, income tax benefit from discontinued operations, depreciation and amortization expense, im pairment loss on digital tokens and stock - based compensation expense. The Company presents Adjusted EBITDA because it is a key measure used by the Company’s management and i ts Board of Directors to understand and evaluate the Company’s core operating performance and trends, to develop short - and long - term operational plans, and to allocate resources to expand the Company’s business. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA can provide a useful measure for period - to - period comparisons of the cash ope rating income generated by the Company’s business. The Company believes that Adjusted EBITDA is useful to investors and others to understand and evaluate the Company’s operating re sul ts and it allows for a more meaningful comparison between the Company’s performance and that of competitors. Management also uses non - GAAP financial measures internally in analyzing the Company's financial results to assess operational performance and to determine the Company's future capital requirements. The presentation of this financial information is not in tended to be considered in isolation or as a substitute for the financial information prepared in accordance with GAAP. Some limitations of Adjusted EBITDA as a financial measure include that: • Adjusted EBITDA does not (i) reflect cash capital expenditure requirements for assets underlying depreciation and amortizatio n e xpense that may need to be replaced or for new capital expenditures; (ii) reflect the Company's working capital requirements; (iii) reflect the impairment loss on digital tokens; o r ( iv) consider the potentially dilutive impact of stock - based compensation; and • Other companies, including companies in our industry, may calculate Adjusted EBITDA differently or choose not to calculate Ad jus ted EBITDA at all, which reduces its usefulness as a comparative measure. Because of these limitations, you should consider this non - GAAP financial information along with other financial performance mea sures reported in our filings with the Securities and Exchange Commission, including total revenues, subscription revenue, deferred revenue, net income (loss), cash and cash equivalents, r est ricted cash, net cash used in operating activities and our financial results presented in accordance with GAAP. The following unaudited table presents a reconciliation of net income (loss), the most directly comparable financial measure cal culated and presented in accordance with GAAP, to Adjusted EBITDA for the year ended December 31, 2018 and the six months ended June 30, 2019 and 2018 (in thousands): Non - GAAP Reconciliation: Adjusted EBITDA 21 21
