Description of Business	1. Description of Business We develop, sell and support products that protect any-sized company or government organization by fusing advanced threat intelligence with real-time artificial intelligence to kill cyberattacks as they occur – including Zero-Days. We market and distribute our solutions through a direct sales force and value-added resellers. Our end-user customers include U.S. federal government entities, state and local government entities, and companies ranging in size from mid-market to large enterprises. References to the “Company”, “we”, “us”, “our”, “Intrusion” or “Intrusion Inc.” refer to Intrusion Inc. and its subsidiaries. *Savant™ and TraceCop*™ are registered trademarks of Intrusion Inc. As of December 31, 2020, we had cash and cash equivalents of approximately $16,704,000, up from approximately $3,334,000 as of December 31, 2019. We generated a net loss of $6,518,000 for the year ended December 31, 2020 compared to a net income of $4,465,000 for the year ended December 31, 2019. Based on the current forecast for the year 2021, we believe that we will have sufficient cash resources to finance our operations and expected capital expenditures through March 31, 2022. As of October 24, 2019, our funding available terminated under an unsecured revolving promissory note to borrow up to $3,700,000 from G. Ward Paxton, the Company’s former Chief Executive Officer (the “CEO Note”). Our management will be assessing whether to replace this borrowing base and assessing what terms may be available to the Company, including whether any such terms available are acceptable to the Company, if at all (the “Potential Replacement Facility”). Any equity or debt financings, if available at all, may be on terms which are not favorable to us and, in the case of equity financings, may result in dilution to our stockholders. We expect to fund our operations through anticipated Company profits, possibly additional investments of private equity and debt, which, if we are able to obtain, will have the effect of diluting our existing common stockholders, perhaps significantly, and a possible Potential Replacement Facility. If our operations do not generate positive cash flow in the upcoming year, or if we are not able to obtain additional debt or equity financing on terms and conditions acceptable to us, if at all, we may be unable to implement our business plan, fund our liquidity needs or even continue our operations.
