<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Nanophase Technologies Corporation (&#8220;Nanophase&#8221; or the &#8220;Company&#8221;, including &#8220;we&#8221;, &#8220;our&#8221; or &#8220;us&#8221;) is a skin and sun care focused company that offers engineered materials, formulation development and commercial manufacturing with an integrated family of technologies. The Company was incorporated in Illinois on November 25, 1989 and became a Delaware corporation during November 1997. Our common stock trades on the OTCQB marketplace under the symbol NANX. We have development and application laboratories and manufacturing capacity in two locations in the Chicago, Illinois, area.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">In recent years, we have advanced and expanded our expertise in nanoscale engineering to include non-nano materials as well as an array of skin care formulations designed to address skin health while imparting an excellent sensory experience. We produce materials for use in three business areas: personal care ingredients, including ingredients for use in sunscreens as active ingredients; fully formulated cosmetics of our own design which are developed, marketed and distributed under the Sol&#233;sence<sup>&#174;</sup> brand name by our wholly owned subsidiary Solesence, LLC (identified throughout this report as our Sol&#233;sence<sup>&#174;</sup> subsidiary); and, to a lesser extent, in our advanced materials products, which include architectural coatings, industrial coatings, abrasion-resistant additives, plastics additives, medical diagnostics, and a variety of surface finishing technologies (polishing) applications, including optics.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Although our technology can be applied to a wide variety of applications, we have focused our efforts on only a handful of applications to gain a depth of knowledge and maximize our potential to grow rapidly. In particular, we have refined our development focus primarily to the personal care market, focusing on skin health. If we find a unique application outside of our core markets that does not require significant development resources, then we may pursue it as &#8220;opportunistic&#8221; business, but we currently have not made a definitive decision to extend our primary development focus outside the personal care market. We believe this focused approach will contribute to a higher success rate for related opportunities than we would experience by pursuing more opportunities simultaneously.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We have developed proprietary technology to disperse nano- and non-nano-particles in both aqueous (water-based) and several organic solvent systems. These dispersions are stable at high weight loading (typically 18-55% by weight). These aspects provide distinct market advantages. Dispersed materials are desired by many customers for use in their processes or products because of the ease of incorporation.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Most of the raw materials we use are readily commercially available. In some cases, we rely on sole-source processors of materials that utilize an array of worldwide sources for the raw materials that they process to our specifications. In certain cases, moreover, certain raw materials that we deal with have a very limited supply, such as cerium oxide, classified as &#8220;Rare Earth elements,&#8221; for use in surface finishing technologies (polishing) applications, as well as the very high purity zinc that we use in personal care applications. Although we currently believe we have developed adequate commercial relationships to supply the necessary raw materials for our business which are not readily commercially available, our business is subject to the pricing and availability of certain raw materials.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We rely on a combination of patent, trademark, copyright, trade secret and other intellectual property laws, nondisclosure agreements and other protective measures to protect our intellectual property. In addition to obtaining patent and trademarks based on our inventions and products, we may also license certain third-party patents from time-to-time to expand our technology base.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">As of the date of this filing, we own 9 U.S. patents and 4 pending U.S. patent applications. We also own 41 foreign patents and patent applications consisting of 31 issued or allowed foreign patents and 10 pending foreign patent applications. All of the pending and owned foreign patents are counterparts to domestic filings covering our platform of nanotechnologies and surface treatments. We have 1 U.S. patent, along with their 5 foreign counterparts, that are set to expire in 2020. We do not believe that the expiration of these patents will have a material impact on our business or financial condition.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;"><b>Competition<a name="ntca009"></a></b></p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Within each of our targeted markets and product applications, we face potential competition from advanced materials and chemical companies, and suppliers of traditional materials. In many markets, the actual or potential competitors are larger and more diversified than we are; however, we believe we focus in market segments and opportunities where our materials and related technologies are superior to those of our competitors, often due to our ability to produce highly engineered products to meet specific performance requirements and develop advanced material solutions for customers&#x2019; specific applications.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">With respect to traditional suppliers, we may compete against lower priced traditional materials for certain customer applications. In some product or process applications the benefits of using nanomaterials do not always justify a process change or outweigh their frequently higher costs.&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">With respect to larger producers of nanomaterials, while many of these producers do not currently offer directly competitive products, these companies may have greater financial and technical resources, larger research and development staffs, and greater manufacturing and marketing capabilities, and could compete directly against us. In addition, the number of development-stage companies involved in nanocrystalline- and advanced-materials continue to grow on a global basis, posing increasing competitive risks. Many of these companies are associated with university or national laboratories and use chemical and physical methods to produce nanocrystalline materials. We believe that most of these companies are engaged primarily in funded research and not commercial production; however, they may represent competitive risks in the future. Some development-stage companies, especially in other countries, receive significant government assistance or enjoy other benefits due to their location. We anticipate that foreign competition will continue to play an important role in the nano- and advanced-materials arena in the future, something we see regularly, albeit indirectly.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We believe that our material technologies and manufacturing platforms are strong. We believe we are well-positioned with our platform of integrated commercial material technologies and track record of technology improvement and evolution.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">In addition to competition in the advanced materials and related markets, our Sol&#233;sence<sup>&#174;</sup> subsidiary faces competition from a wide variety of offerings in the field of skin care. Our Sol&#233;sence<sup>&#174;</sup> products compete with existing solutions as well as new solutions from various sources, including other product developers who seek to serve skin care brands and integrated brands who also manufacture their own products in-house, and we must differentiate their value proposition in order to gain traction in this marketplace. We believe that our Sol&#233;sence<sup>&#174;</sup> technology, coupled with our expanding product formulations capability, will allow us to become a competitive player in this market.<b> </b></p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">The manufacture and use of certain of the products that contain Active Pharmaceutical Ingredients are subject to governmental regulations. As a result, we are required to adhere to the cGMP requirements of the FDA and similar regulations that include testing, control and documentation requirements enforced by periodic inspections. We have registered some of the chemicals we ship to customers in Europe in compliance with the European Chemical Agency&#x2019;s regulations issued to date pertaining to REACH (to date, we have registered Zinc Oxide, Aluminum Oxide, Iron Oxide and Octyltrimethoxysilane under REACH).</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We are committed to environmental health and safety (&#8220;EH&amp;S&#8221;). We believe we comply with all applicable exposure limit standards issued by OSHA. Because nanotechnology remains an emerging and evolving science, there are no currently accepted standards, measurements or personal protective equipment available that are specific to nanoparticle safety. Accordingly, we rely on general chemical safety and process safety practices to identify safe personal protective equipment and appropriate handling protocols. We believe that we have taken a leadership position on EH&amp;S in our operations and have internal and external review and monitoring of our practices.</p>

We believe we are in compliance with all such laws and regulations, and to date, those regulations have not materially restricted or impeded operations. Further, we believe our processes to be highly efficient, generating very low levels of waste and emissions. For this reason, we do not view issues surrounding climate change and any currently foreseeable related regulations as materially impacting our business and financial statements, beyond any inestimable impact on the macro-economic environment.&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We have taken a responsible, proactive approach to EH&amp;S by implementing appropriate procedures and processes to have our facilities registered under ISO 14001, American National Standard, Environmental Management System Requirements. We are also involved with leading industry groups that are defining nanomaterial standards and protocols. These currently include the ASTM International Committee on Nanotechnology, and the US TAG to ISO TC 229 Nanotechnology committee managed by the American National Standards Institute committee (ANSI). We also participate in FDA reviews relative to cosmetic and applicable drug applications. We have a full-time, advanced degreed professional who spends a significant amount of time managing governmental regulation compliance and EH&amp;S.

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">On December 31, 2019, we had a total of 53 full-time employees, 5 of whom hold advanced degrees. Additionally, we have a number of temporary, and temporary-to-permanent employees and contractors with specific industry experience that have become a part of our talent pool. We have no collective bargaining agreements and believe that we have a strong relationship with our employees, whom management believes represent the strength of our Company.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We do not believe that a backlog as of any particular date is indicative of future results. Our sales are primarily pursuant to purchase orders for delivery of our personal care ingredients, advanced materials and Sol&#233;sence<sup>&#174;</sup> formulated products. We have some agreements that give customers the right to purchase a specific quantity of nanomaterials during a specified time period. These agreements, however, do not obligate the customers to purchase any minimum quantity of such nanomaterials. The quantities actually purchased by the customer, as well as the shipment schedules, are frequently revised during the agreement term to reflect changes in the customer&#x2019;s needs. For these reasons we do not believe that such agreements are meaningful for determining backlog amounts.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">A limited number of key customers account for a substantial portion of our commercial revenue, and aside from our largest customer, we are seeing the composition of these key customers change with the growth we are experiencing within our Sol&#233;sence<sup>&#174;</sup> subsidiary. In particular, revenue from two customers - the largest customer in our personal care ingredients business (BASF), and the first significant customer for our Sol&#233;sence<sup>&#174;</sup> products (Colorescience)constituted approximately 63%, and 8%, respectively, of our 2019 total revenue. As our Solesence products continue to represent more of our total revenues, we expect to see a number of smaller (sub-10% of revenue) customers represent a more significant portion of our total revenue.&nbsp; Many of our customers are significantly larger than we are and, therefore, may be able to exert a high degree of influence over us. While our agreements with BASF are long-term agreements, they may be terminated by BASF under certain circumstances with reasonable notice and do not provide any guarantees that BASF will buy our products. The loss of one of our largest customers or the failure to attract new customers could have a material adverse effect on our business, results of operations and financial condition. Due to the high concentration of sales to a limited number of customers, we have aggressively pursued new customers through our customer direct business model. To the extent we are successful in adding a large number of customers through this model and maintaining or expanding our existing partners, we believe we will be able to best manage the risks associated with customer concentration.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We operate two facilities in the Chicago suburbs - a 36,000 square-foot production, research and headquarters facility in Romeoville, Illinois and a 20,000 square-foot production facility in Burr Ridge, Illinois. We also lease a 13,000 square-foot offsite warehouse in the vicinity of the Romeoville facility.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Our manufacturing operations in Burr Ridge are registered under ISO 9001, and we believe that our manufacturing operations are within the cGMP requirements of the FDA for products that require such compliance. Our facilities are also registered under ISO 14001 which is the international standard for environmental management.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">The Romeoville facility houses our headquarters, advanced engineering, manufacturing (including nanoparticle coating, nanoparticle dispersion and pilot-scale manufacturing) and research and development with three applications development and formulating laboratories. The Romeoville facility has a quality control laboratory designed for the dual purposes of validating operations to cGMP and ISO standards and production process control. This laboratory is equipped to handle many routine analytical and in-process techniques that are currently required. All Romeoville manufacturing processes are registered under ISO 9001 and ISO 14001, and we believe that the particle coating processes used for our ingredients and fully formulated sunscreens and cosmetic products for personal care are in compliance with the cGMP requirements of the FDA.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We lease our Romeoville and Burr Ridge facilities. During October 2016 we entered into an amendment to our Industrial Lease Agreement for the facility in Romeoville, Illinois, which, among other things, extended the term of such lease through December 31, 2024. On March 14, 2017, we entered into a new Building Lease for the Burr Ridge facility that began in September 2017 and will end during September 2021, with our option to further extend this lease by three additional one-year periods. On August 6, 2019 we entered into a new warehouse lease for a different property in Romeoville that began in September 2019 and will end in September 2022, with our option to extend this lease for one additional year.&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We believe that our leased facilities provide sufficient capacity to fulfill current known customer demand as well as allow for the creation of substantial additional space to enable expansion of key production processes. We believe additional facilities could be obtained in the area at competitive prices, if necessary, to support growth. We believe that our capital expenditures made in 2019, and projected for 2020, will support currently anticipated demand from existing and expected customers through 2020. Our actual future capacity requirements will depend on many factors, including new and potential customer acceptance of our current and potential engineered materials, applications and products, both expected and currently unplanned growth from existing customers, continued progress in our research and development activities and product testing programs and the magnitude of these activities and programs.<b> </b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Nanophase is a skin health focused company that offers engineered materials, formulation development and commercial manufacturing with an integrated family of technologies. Our expertise in small particle engineering allows us to effectively coat and disperse particles on a nano and &#8220;non-nano&#8221; scale for use in a variety of diverse markets: personal care ingredients, including sunscreens as active ingredients; full formulations of skin care products, marketed and sold by our wholly owned subsidiary, Solesence, LLC (referred to in this report as our &#8220;Sol&#233;sence<sup>&#174;</sup> subsidiary&#8221;); and in our advanced materials line of business for use in architectural coatings, industrial coating applications, abrasion-resistant additives, plastics additives, medical diagnostics, and a variety of surface finishing technologies (polishing) applications, including optics.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; margin-top: 0pt; margin-bottom: 0pt;"><b>Critical Accounting Estimates</b></p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We review long-lived assets for impairment whenever events or changes in circumstances indicate that the asset&#x2019;s carrying amount may not be recoverable. We conduct long-lived asset impairment analyses in accordance with Financial Accounting Standards Board (&#8220;FASB&#8221;) Accounting Standards Codification (&#8220;ASC&#8221;) Topic 360-10-15, <i>Impairment or Disposal of Long-Lived Assets</i>. ASC 360-10-15 requires us to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Certain assumptions are necessary to assess the impact of risks and uncertainties on the financial information, such as cash flow projections, availability of capital if needed to support the ongoing operations of the business, and our expected compliance with contractual commitments. Any changes in those plans or assumptions could have a material impact on our liquidity and financial condition.&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0pt 0pt 32.4pt;"><b>Years Ended December 31, 2019 and 2018</b></p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Total revenue decreased to $12,509,000 in 2019, compared to $14,193,000 in 2018. A substantial majority of our revenue for each year is from our largest customers, in particular, sales to our largest customer in skin care and sunscreen applications. Product revenue, the primary component of our total revenue, decreased to $11,852,000 in 2019, compared to $14,040,000 in 2018. This decrease was due mainly to a decrease in revenue from our largest customer (Personal Care), from 74% of revenue in 2018 to 63% of revenue in 2019, while our largest Soles&#233;nce<sup>&#174;</sup> (Finished Packaged Consumer Products) customer had roughly equal revenue in 2018 and 2019. Revenue from our top two customers - the largest customer in our personal care ingredients business (BASF), and the first significant customer for our Sol&#233;sence<sup>&#174;</sup> products (Colorescience) constituted approximately 63%, and 8%, respectively, of our 2019 total revenue, compared to 74% and 7%, respectively, for the same customers in 2018.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Other revenue increased to $657,000 in 2019, compared to $153,000 in 2018. This increase primarily related to a contractual fee to our largest customer relating to rapid changes in required capacity not in keeping with their forecast, and to the payment for goods manufactured that a Solesence customer subsequently decided to reformulate, taking a different version to market, both of which&nbsp; management has classified as &#8220;other revenue.&#8221; Other revenue also includes customer-paid shipping charges, and any other customer-paid development projects.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Cost of revenue generally includes costs associated with commercial production and customer development arrangements. Cost of revenue decreased to $9,893,000 in 2019, compared to $10,903,000 in 2018. The decrease in cost of revenue was primarily driven by the decrease in product revenue volume, along with a degree of manufacturing inefficiencies relating to several new customer start-up campaigns for our Solesence products. Our annual gross margin decreased by approximately 2% when compared to that of the prior year. Part of this decrease was created by a write-down of inventory of $390,000 in 2019, resulting in a 3% reduction in gross margin percentage by itself, most of which was recognized in the fourth quarter.&nbsp; We expect to continue new materials development and dispersion technologies for personal care applications, for our formulated Sol&#233;sence<sup>&#174;</sup> products during 2020 and beyond. At current revenue levels we have generated a positive gross margin, though margins have been impeded by not having enough revenue to efficiently absorb manufacturing overhead that is required to work with current customers and expected future customers.&nbsp; We believe that our current fixed manufacturing cost structure is sufficient to support significantly higher levels of revenue volume. The extent to which margins grow, as a percentage of total revenue, will be dependent upon revenue mix, revenue volume, our ability to continue to cut costs and pass commodity market-driven raw materials increases on to customers, and the speed and efficiency with which we are able to scale up production for our Sol&#233;sence<sup>&#174;</sup> products. We expect that, as product revenue volume increases, our fixed manufacturing costs will be more efficiently absorbed, which should lead to increased margins as we grow. We expect to continue to focus on reducing controllable variable product manufacturing costs, with potential variability related to the commodity metals markets, but may or may not realize absolute dollar gross margin growth through 2020 and beyond, dependent upon the factors discussed above.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Research and development expense, which includes all expenses relating to the technology and advanced engineering groups, primarily consists of costs associated with the development or acquisition of new finished product formulations for skin care, new product applications for our skin care ingredients, and coating formulations and the cost of enhancing our manufacturing processes. As an example, we are currently focusing the bulk of our resources on developing new product formulations, and related new technologies, as we expand marketing and sales efforts relating to our Sol&#233;sence<sup>&#174;</sup> products. This work has led to several new products and additional potential new products. Our efforts in research and development, cosmetic formulating, process engineering and advanced engineering groups are focused in three major areas: 1) application development for our products; 2) creating or obtaining additional core material technologies and/or materials that have the capability to serve multiple skin health-related markets; and 3) continuing to improve our core technologies to improve manufacturing operations and reduce costs.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Research and development expense decreased to $1,870,000 in 2019, compared to $2,057,000 in 2018. The primary reasons for this decrease were reductions in outside testing, salaries and consulting, and materials charges associated with the development and launch of our Sol&#233;sence<sup>&#174;</sup> line of personal care products and related capabilities. We also decreased patent legal spending in 2019, in part due to there being more initial work required in both areas in 2018 as Solesence business development started to expand.&nbsp; We expect similar-to-marginally higher spending in this area during 2020 as we continue with these efforts<b>.</b></p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Selling, general and administrative expense increased to $3,542,000 in 2019, compared to $3,256,000 in 2018. The net increase was primarily attributed to temporary help and severance charges, neither of which we expect to repeat at this magnitude, professional fees which include audit and legal, exhibitions and tradeshows, and software upgrades and related IT costs. We expect 2020 expenses in this area to be approximately 3% lower, despite expected increases in Solesence revenue, and driven largely by the selling function, as we plan to continue expanding our Solesence product launches in skin health, and other areas, depending on the status of certain initiatives.<b> </b></p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Interest expense was $210,000 in 2019, compared to $58,000 in 2018, due mainly to the impact of our revolving line of credit for working capital funding and capital leases and term loans supporting some of our equipment.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We believe inflation has not had a material effect on our operations or financial position. However, supplier price increases and wage and benefit inflation, both of which represent a significant component of our costs of operations, may have a material effect on our operations and financial position in 2020 and beyond if we are unable to pass through any increases under present contracts or through to our markets in general.</p>

to $1,194,000 as of December 31, 2019, compared to $1,345,000 as of December 31, 2018. The cash used in operating activities for
the year ended December 31, 2019 was $2,776,000 compared to $1,342,000 used for the year ended December 31, 2018. This was in part
due to an increase in inventories and accounts receivable, and a decrease in accrued expenses, partially offset by increases in
accounts payable and deferred revenue as of December 31, 2019. Net cash used in investing activities amounted to $40,000 for the
year ended December 31, 2019, compared to $160,000 for the year ended December 31, 2018. Cash capital expenditures amounted to
approximately $740,000 and $160,000 for the years ended December 31, 2019 and 2018, respectively. We did not dispose of or sell
any assets during 2019 or 2018.</p>

by financing activities was $3,365,000 in 2019, compared to $892,000 in 2018. On May 13, 2019, we sold 4,189,000 shares of our
common stock to our largest investor for $1,677,000 in proceeds, and had no such sales during 2018. On November 20, 2019, we closed
on a Convertible Note from the Company with our largest investor, resulting in $2,000,000 in proceeds. The primary use of these
funds has been to fund growth, to support the Company&rsquo;s expanding working capital needs, and to fund capital equipment.
No selling commission or other remuneration was paid in connection with either transaction.&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">During March 2018, we executed a new business loan agreement with Libertyville (the &#8220;New Line of Credit Agreement&#8221;) on substantially similar terms, except the revolving credit limit was increased from $300,000 to $500,000, and there were certain limitations imposed on our ability to, among other things, incur additional indebtedness for borrowed money outside the ordinary course of business (like a capital lease, receivables factoring or a mortgage), sell, lease or use our assets as collateral for additional credit, pay cash dividends or engage in certain business transactions without Libertyville&#x2019;s prior written consent. Outstanding borrowings were $0 and $300,000 on this line of credit as of December 31, 2018, and December 31, 2017, respectively. The maturity date for the New Line of Credit Agreement was March 4, 2019. During March 2019, we executed a new business loan agreement with Libertyville (the &#8220;New Business Loan Agreement&#8221;) on substantially similar terms, with the addition of mirroring the requirements for holding $500,000 in inventory and other non-cash items that are discussed within the most recent amendment to the BASF supply agreement in lieu of cash. The New Business Loan Agreement has a maturity date of April 4, 2020. On November 16, 2018, we entered into a Business Loan Agreement (the &#8220;Master Agreement&#8221;) with Beachcorp, LLC. The Master Agreement relates to two loan facilities, each evidenced by a separate promissory note dated as of November 16, 2018: a term loan to the Company of up to $500,000 to be disbursed in a single advance (the &#8220;Term Loan&#8221;) with a fixed annual interest rate of 8.25%, payable quarterly, accruing from the date of such advance and with principal due on December 31, 2020; and an asset-based revolving loan facility for the Company of up to $2,000,000 (the &#8220;Revolver Facility&#8221;), with floating interest accruing at the prime rate plus 3% (8.25% minimum) per year, with a borrowing base consisting of qualified accounts receivable of the Company, and with all principal and accrued interest due March 31, 2020.&nbsp; On March 23, 2020, the Company and Beachcorp, LLC executed the First Amendment to our Master Agreement that extends the maturities of both the Term Loan and the Revolver Facility to March 31, 2021.&nbsp; The Term Loan and Revolver Facility are secured by all the unencumbered assets of the Company and subordinated to Libertyville&#x2019;s secured interest under the New Business Loan Credit Agreement.&nbsp; On May 13, 2019, we sold 4.2 million shares of our common stock to our largest investor for $1.7 million in proceeds and had no such sales during 2018. No selling commission or other remuneration was paid in connection with this transaction.&nbsp; In November we entered in to a 2% Convertible Promissory Note in the original principal amount of $2,000,000.&nbsp; This note matures on May 15, 2024, and is payable to our investor at that time in cash, or through conversion of the rights to purchase up to 10,000,000 unregistered shares of the Company&#x2019;s common stock at $0.20 per share.&nbsp; The conversion can be done in full or in part, and may be undertaken prior to the note&#x2019;s maturity date.&nbsp; The Master Agreement substantially restricts the Company&#x2019;s ability to incur additional indebtedness during the terms of the Term Loan, the Revolver Facility, and the Convertible Promissory Note. On December 31, 2019, the balances on the Term Loan and the Convertible Promissory Note were $500,000 and $2,000,000, respectively, and the balance on the Revolver Facility was $224,000.

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt;  margin-top: 0pt; margin-bottom: 0pt;">Our supply agreements with our largest customer, BASF, contain certain financial covenants which could potentially impact our liquidity. The most restrictive financial covenants under these agreements require that we maintain a minimum of $1,000,000 in certain current assets; which may be composed of no less than $500,000 cash, cash equivalents, and certain investments, no more than a combined $500,000 of certain related inventory, of which no more than $250,000 can be raw material, and certain receivables, and that we not have the acceleration of any debt maturity having a principal amount of more than $10 million, in order to avoid triggering the customer&#x2019;s potential right to transfer certain technology and equipment to that customer at a contractually-defined price. At December 31, 2019, we had approximately $1.2 million in cash, and total availability under our revolving loans from Libertyville and Beachcorp, LLC of $874,000. At December 31, 2018, we were technically overdrawn on the Beachcorp, LLC line of credit by $192,000, which was absorbed by an increase in the borrowing base in early January. This was due to the mechanics of the control account not being fully established, and has been resolved. This supply agreement and its covenants are more fully described in Note 13, and our line of credit is more fully described in Note 4, to our Financial Statements referred to in Part II, Item 8, of this Annual Report on Form 10-K.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">We believe that cash from operations and cash on hand, in addition to unused borrowing capacity, may not be adequate to fund our operating plans through 2020.&nbsp; We are working to reduce these risks, but some of this is dependent on several things over which we have limited control. We have seen an increase in sales of our Sol&#233;sence<sup>&#174;</sup> products in late 2019, which we expect to continue, but to a greater extent, in 2020. This may require additional investment in working capital. Given these issues, and other commercial realities, we are monitoring the additional working capital demands that this could create as we continue to execute on our Sol&#233;sence<sup>&#174;</sup> growth strategy. The timing of cash flows is critical. If cash generated from operations is not materially consistent with our plans, we believe that we may need to seek additional funding to address working capital demands. This uncertainty has caused us to be unable to assert that, for the next twelve months, we have enough current cash and guaranteed access to financing to fund operations, and to continue with our current growth strategy in terms of investment in capital equipment and in operating expenses related to Solesence<sup>&#174;</sup>, without securing additional financing. We believe that we will be able to secure additional financing if needed, but we do not have any additional financing commitments in place as of today. However, we may not be able to secure additional financing in a timely manner under commercially reasonable terms, or at all. If we are unable to secure additional financing, the operations of the Company might need to be curtailed to a certain degree, and we would need to delay capital expenditures related to our Sol&#233;sence<sup>&#174;</sup> growth strategy, which could impede growth in 2020 and 2021.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">Our actual future capital requirements in 2020 and beyond will depend on many factors, including customer acceptance of our current and potential engineered materials, applications, and products, continued progress in research and development activities and product testing programs, the magnitude of these activities and programs, and the costs necessary to increase and expand our manufacturing capabilities and to market and sell our engineered materials, applications, and products. Other important issues that will drive future capital requirements will be the development of new markets and new customers as well as the potential for significant unplanned growth with existing customers. Depending on the success of certain projects, we expect that capital spending relating to currently known capital needs for 2020 will be between $300,000 and $800,000, to be funded by our existing loans and lines of credit. If those projects are delayed or ultimately prove unsuccessful, or if we fail to be able to support the additional cost of funding them in the near term, we would expect our capital expenditures may fall below the lower end of the range. Similarly, substantial success in business development projects may cause the actual 2020 capital investment to exceed the top of this range.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt;">&nbsp;</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 36.0pt; margin-top: 0pt; margin-bottom: 0pt;">In the likely event that we will need to seek additional financing, such additional financing may not be available on acceptable terms or even at all, and any such additional financing could be dilutive to our shareholders. Such financing could be necessitated by such things as the loss of an existing customer; a significant decrease in revenue from one or more of our customers; temporary working capital demands resulting from our expected growth in our Sol&#233;sence<sup>&#174;</sup> business that we cannot fund with existing capital; currently unknown capital requirements considering the factors described above; new regulatory requirements that are outside our control; the need to meet previously discussed cash requirements to avoid a triggering event under our BASF agreement; or various other circumstances coming to pass that we currently do not anticipate. The failure to have access to sufficient capital to fund our business plans may result in a curtailment or other change in those plans, and under such circumstances, this raises doubt as to our ability to continue as a going concern.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 24.5pt; margin-top: 0pt; margin-bottom: 0pt;">On December 31, 2019, we had a net operating loss carryforward of approximately $77 million for income tax purposes. Because the Company may have experienced &#8220;ownership changes&#8221; within the meaning of the U.S. Internal Revenue Code (&#8220;IRC&#8221;) in connection with its various prior equity offerings, future utilization of this carryforward may be subject to certain limitations as defined by the IRC. If not utilized, $72 million of this loss carryforward will expire between 2020 and 2037.&nbsp; Given changes to the IRC, net operating loss carryforwards generated after January 1, 2018 do not expire, therefore, $5 million in net operating losses generated since January 1, 2018 do not expire.</p>

It should be noted that in designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and that our management necessarily was required to apply its judgment regarding the design of our disclosure controls and procedures. As of the end of the period covered by this report, we conducted an evaluation, under the supervision (and with the participation) of our management, including our Chief Executive Officer (our principal executive officer) and our Chief Financial Officer (our principal financial officer), of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at reaching that level of reasonable assurance.</p>

of the accountants&rsquo; annual audit, reviewing the Company&rsquo;s internal control functions and financial management policies,
reviewing and approving all related party transactions, and reporting to the Board of Directors regarding all of the foregoing.
The Audit and Finance Committee held five meetings during 2019. The Board of Directors has determined that Mr. Vincent is an &ldquo;audit

that Ms. Whitmore is independent under the Nasdaq Stock Market rules, but such rules are inapplicable to the Company because the

Compensation Committee does not delegate any of its functions to others in setting compensation. The Compensation Committee does
not currently utilize external consultants in executive or director compensation matters. The Compensation Committee held three

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Board of Directors
considers its role in risk oversight to focus primarily on evaluating risk at the entity and strategic levels, with management
primarily responsible for managing day-to-day risk factors and presenting summary materials for those positions to the Board of
Directors. Consistent with this philosophy, the Board of Directors has no formal policy as to whether the roles of Chief Executive
Officer and board Chair should be segregated or combined. The Board of Directors considers the circumstances of the Company and
makes a determination as to the appropriate leadership structure for the Company at that time. As of the time of this filing, the
positions of CEO and Board Chair are held by two individuals &ndash; Ms. Whitmore serves as Chair and Mr. Jankowski serves as CEO.
Ms. Whitmore brings extensive experience in corporate leadership from her own working experience and from a number of boards on
which she has served in the past, and Mr. Jankowski is expected to benefit from that experience. The Board of Directors believes
that is the most appropriate structure for the Company at this time. Under our Corporate Governance Principles, in the event that
the Chair of the Board is not an Outside Director, the Board will elect a lead independent director, who will have the responsibility
to schedule and prepare agendas for meetings of the Outside Directors, communicate with the CEO, disseminate information to the
rest of the Board and raise issues with management on behalf of the Outside Directors when appropriate. The Board evaluates its
leadership structure on an ongoing basis and may change it as circumstances warrant.</P>

in areas directly applicable to the Company or its intended future endeavors.</P>

    <td style="text-align: justify"><FONT STYLE="font-size: 10pt">Any amounts earned during 2019 and 2018 would have been paid in early 2020 and 2019, respectively. Bonus compensation is driven by Company performance against its goals as ultimately determined by the Compensation Committee of the Board of Directors. A set of Company-level objectives is created at the beginning of the year, focusing on total revenue, revenue growth, particular sources of revenue growth, business development achievements, cash flows and related targets, as well as a small discretionary component designed to capture items not specifically listed. Each measure has varying levels of achievement, which is reflected in the aggregate bonus measurement. The resulting bonus calculation is then applied to each individual&rsquo;s bonus potential as a percentage of salary. Although the Solesence business achieved many critical milestones in 2019, and total revenue growth was approximately 13% during 2018, performance targets were not met and thus no bonus was awarded to any of the named executive officers for 2019 or 2018.</FONT></TD></TR>

in control. Under the Director Deferred Compensation Plan, the deferred fees that would have been paid in cash are deemed invested
in 5-year U.S. Treasury Bonds during the deferral period. The accumulated hypothetical earnings are paid following the Outside
Director&rsquo;s separation from service or the Company&rsquo;s change in control. The deferred fees that would have been paid
as restricted shares are deemed invested in our common stock during the deferral period. The Director Deferred Compensation Plan
is an unfunded, nonqualified deferred compensation arrangement. In 2009, all Outside Directors elected to defer receipts of all
of the restricted shares they became entitled to under the Director Restricted Stock Plan, which was consolidated into the 2010
Equity Plan. In November 2019, the 2010 Equity Plan was consolidated in to the 2019 Equity Compensation Plan.</P>

two transactions with Bradford T. Whitmore since January 1, 2019. Together with his affiliates Grace Brothers, Ltd. and Grace Investments,
Ltd., Mr. Whitmore beneficially owned approximately 62.7% of the outstanding shares of our common stock as of March 24, 2020. Mr.
Whitmore is the brother of R. Janet Whitmore, who has been the Chair of the Board of Directors since November 19, 2019 and one
of our directors since 2003, and who is also a stockholder. Through his affiliate Beachcorp, LLC, Mr. Whitmore is also a substantial

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">On May 13, 2019, we sold 4,189,000 shares
of our common stock, $0.01 par value per share (&ldquo;Common Stock&rdquo;) to Mr. Whitmore for an aggregate purchase price of
$1,675,600 representing a price of $0.40 per share of Common Stock. In connection with the sale of Common Stock, the Company entered
into a Common Stock Purchase Agreement, dated May 13, 2019, with Mr. Whitmore, providing for the unregistered sale to Mr. Whitmore
of the number shares of Common Stock stated above for the consideration stated above and otherwise including representations, warranties
and registration rights which are customary for similar private placements. The complete text of the Common Stock Purchase Agreement,
dated May 13, 2019, between the Company and Mr. Whitmore was filed as Exhibit 4.1 to the Company&rsquo;s Quarterly Report on Form
10-Q for the fiscal quarter ended March 31, 2019, which was filed with the SEC on May 15, 2019, and this summary is qualified in

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">On November 13, 2019,
we entered into a Securities Purchase Agreement (the &ldquo;SPA&rdquo;) with Mr. Whitmore pursuant to which he agreed to purchase
a Convertible Note (see below) from the Company for $2,000,000 and otherwise including representations, warranties and covenants
which are customary for similar transactions. The transactions contemplated by the SPA closed on November 20, 2019. At the closing
of the SPA on November 20, 2019, the Company sold to Mr. Whitmore, and Mr. Whitmore purchased from the Company, a 2% Secured Convertible
Promissory Note in the original principal amount of $2,000,000 (the &ldquo;Convertible Note&rdquo;), the principal amount of which
is payable to the order of Mr. Whitmore and his registered assigns and successors in a single payment on May 15, 2024 (the &ldquo;Maturity
Date&rdquo;). The principal amount of the Convertible Note accrues interest at the rate of 2.0% per year, which interest is payable
semi-annually on the 15th day of May and November, commencing on May 15, 2020. The principal amount and, at the holder&rsquo;s
option, accrued interest under the Convertible Note is convertible at the holder&rsquo;s option into additional shares of the Company&rsquo;s
common stock in whole or in part and from time to time up to the Maturity Date at a conversion price of $0.20 per share. The obligations
under the Convertible Note are secured by a security interest in all of the Company&rsquo;s personal property pursuant to a Commercial
Security Agreement among Mr. Whitmore, the Company and Sol&eacute;sence, LLC, the Company&rsquo;s sole subsidiary. The SPA also
amended the Common Stock Purchase Agreement, dated May 13, 2019, between the Company and Mr. Whitmore to add the shares of common
stock issuable upon conversion of the Convertible Note to the registration rights granted therein.</P>

late charges) being redeemed.</P>

The Board of Directors has determined that the following Company directors are (or was until his retirement effective January 13,
2020, in the case of Mr. Tyler) &ldquo;independent&rdquo; as that term is defined in the rules and regulations of the SEC and the
Nasdaq Stock Market: Dr. Siegel and Messrs. Tyler and Vincent. Though we are no longer listed on Nasdaq, our Board of Directors
used the Nasdaq listing standards in making its independence determinations. Under the Nasdaq Stock Market rules, the Company would
qualify as a &ldquo;controlled company&rdquo; because of the direct and indirect ownership of Bradford T. Whitmore. As a controlled
company, the Company would be exempt from the requirements under those rules to have a majority of independent directors, to have
an independent compensation committee, or to have independent director oversight of director nominations.</P>

and cash flows for the year<FONT STYLE="color: black">s</FONT> then ended, and the related notes to the consolidated financial

cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.</FONT></P>

accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed
in Note 3 to the financial statements, the Company has suffered recurring losses from operations and has limited liquidity to
fund current operations. This raises substantial doubt about the Company&rsquo;s ability to continue as a going concern. Management&rsquo;s
plans in regard to these matters also are described in Note 3. The financial statements do not include any adjustments that might
result from the outcome of this uncertainty.</FONT></P>

with an integrated family of technologies. Our expertise in nanoscale engineering allows us to effectively coat and disperse particles
on a nano and &ldquo;non-nano&rdquo; scale for use in a variety of diverse markets: personal care ingredients, including sunscreens
as active ingredients; full formulations of skin care products, marketed and sold by our wholly-owned subsidiary, Solesence, LLC
(our &ldquo;Sol&eacute;sence<SUP>&reg;</SUP> subsidiary&rdquo;), which comprise two of our three major product categories; and
in architectural coatings, industrial coating applications, abrasion-resistant additives, plastics additives, medical diagnostics,

end-use applications manufacturers, and our Sol&eacute;sence<SUP>&reg;</SUP> products to cosmetics and skin care brands. Recently
developed technologies have made certain new products possible and opened potential new markets. During 2015 we were granted a
patent on a new type of particle surface treatment (coating) &mdash; now called Active Stress Defense &trade; Technology &mdash;
which became the cornerstone of our new product development in personal care, with first revenue recognized during 2016. In addition,
through the creation of our Sol&eacute;sence<SUP>&reg;</SUP> subsidiary, we utilize this particle surface treatment to manufacture

sold in the personal care area.</FONT></P>

Cash balance on December 31, 2019 consists of funds borrowed from our Convertible Promissory Note, held by Bradford T. Whitmore,
and our Term Loan and Revolving Line of Credit, both of which are facilitated by Beachcorp, LLC. Our ability to access cash from
our credit facility solely depends on carrying an Accounts Receivable balance greater than the outstanding loan balance in the
Revolving Line of Credit. As part of the agreement, we are required to have a bank account in place to act as a depository account
for our customers. This account is referred to as the Control Account. Furthermore, there is an Account Control Agreement in place
which provides Beachcorp, LLC the ability to exercise control over the account via approval of requested transfers. According
to our agreements with Beachcorp, LLC, Nanophase is to be the party initiating any transfers, whether to Nanophase or to Beachcorp,
LLC, and approval to access any monies within this account can only be withheld by Beachcorp, LLC if the borrowing base falls
below the Company&rsquo;s qualified receivables, or if we are in arrears with respect to interest payments due Beachcorp, LLC.
The failure of Nanophase to remedy the previously mentioned conditions could lead to Beachcorp, LLC gaining the right, through
a &ldquo;springing&rdquo; feature administered by Libertyville Bank and Trust, a Wintrust Community Bank (&ldquo;Libertyville&rdquo;),
to transfer funds to itself without direct approval from Nanophase. Due to the restrictive nature on this account to Nanophase
Technologies Corporation, any balance in the account constitutes restricted cash. The restricted cash balance in this account
on December 31, 2019 was zero.</FONT></P>

account for income taxes using the liability method. As such, deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.
Deferred tax assets and liabilities are calculated using the enacted tax rates and laws that are expected to be in effect when
the anticipated reversal of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance
when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets will not be realized.</FONT></P>

tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities,
while others are subject to uncertainty about merits of the position taken or the amount of the position that would be ultimately
sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available
evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution
of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions
that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50
percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated
with tax positions taken that exceeds the amount measured, as described above, is reflected as a liability for uncertain tax benefits
in the accompanying balance sheets along with any associated interest and penalties that would be payable to the taxing authorities
upon examination.</FONT></P>

Leases, ASU No. 2018-10, Codification Improvements to Topic 842 (Leases) and ASU No. 2018-11, Targeted Improvements to Topic 842
(Leases). The guidance is intended to increase transparency and </FONT>comparability among companies for leasing transactions,
including a requirement for companies that lease assets to recognize on their balance sheets the assets and liabilities for the
rights and obligations created by those leases. The guidance also provides for disclosures that allow the users of financial statements
to assess the amount, timing, and uncertainty of cash flows arising from leases.</P>

Company adopted the guidance on January 1, 2019 using the modified retrospective method without restatement of comparative periods.
As such, periods prior to the date of adoption are presented in accordance with ASC 840 - Leases. The Company utilized the available
practical expedient that allowed </FONT>for the Company to not reassess whether existing contracts contain a lease under the new
definition of a lease, lease classification for existing leases and whether previously capitalized initial direct costs would
qualify for capitalization under the new guidance.</P>

adoption of this guidance had a material impact on the Consolidated Balance Sheet as of December 31, 2019 due to the recognition
of equal right-of-use assets and lease liabilities for the Company's portfolio of operating leases. The right-of-use asset balance
was then adjusted by the reclassification of pre-existing accrued rent balances from other line items within the Consolidated
Balance Sheet. The adoption had an immaterial impact to the Consolidated Statement of Cash Flows and to the Consolidated Statement
of Operations for the year ended December 31, 2019. The adoption had no impact to the Consolidated Statement of Changes in Stockholders'
Equity for the year ended December 31, 2019. Additional information and disclosures required by the new standard are contained
in Note 7, Lease Commitments.</FONT></P>

believe that cash from operations and cash on hand, in addition to unused borrowing capacity, may not be adequate to fund our
operating plans through 2020. We are working to reduce these risks, but some of this is dependent on several things over which
we have limited control. Our largest customer made up 63% of our 2019 revenue, and expects a reduction in orders from us in 2020,
which has limited our flexibility and required us to make cash management a top priority. We have seen an increase in sales of
our Sol&eacute;sence<SUP>&reg; </SUP>products in late 2019, which we expect to continue, but to a greater extent, in 2020. This
may require additional investment in working capital. Given these issues, and other commercial realities, we are monitoring the
additional working capital demands that this could create as we continue to execute on our Sol&eacute;sence<SUP>&reg;</SUP> growth
strategy. The timing of cash flows is critical. If cash generated from operations is not materially consistent with our plans,
we believe that we may need to seek additional funding to address working capital demands. This uncertainty has caused us to be
unable to assert that, for the next twelve months, we have enough current cash and guaranteed access to financing to fund operations,
and to continue with our current growth strategy in terms of investment in capital equipment and in operating expenses related
to Solesence<SUP>&reg;</SUP>, without securing additional financing.</FONT></P>

July 2014 we entered into a bank-issued letter of credit and related promissory note for up to $30 in borrowings to support our
obligations under our facility lease agreement. No borrowings have been incurred under this promissory note. Should any borrowings
occur in the future, the interest rate would be the prime rate plus 1%, with the bank having the right to &ldquo;set off&rdquo;
or apply unpaid balances against our checking account if we fail to meet our obligations under any borrowings under the note.
It is our intention to renew this note annually, for as long as we need to do so pursuant to the terms of our facility lease agreement.
Because there were no amounts outstanding on the note at any time during 2019 or 2018, we have recorded no related liability on
our balance sheet.</FONT></P>

maintained a Line of Credit Agreement with Libertyville Bank and Trust Company, a Wintrust Community Bank (&ldquo;Libertyville&rdquo;),
our primary bank during 2018 which had a maturity date of March 4, 2019. There were no borrowings on this line at December 31,
2018. On March 22, 2019, we executed a New Business Loan Agreement with Libertyville, which replaced the maturing Line of Credit
Agreement with Libertyville. Under the New Business Loan Agreement, Libertyville will provide a maximum of (i) $500 or (ii) two
times the sum of (a) 75% our eligible accounts receivables and (b) our cash deposited with Libertyville, whichever is less, of
revolving credit to us, collateralized by a senior priority lien on our accounts receivable, inventory, equipment, general intangibles
and fixtures. Interest is payable monthly on any advances at a floating interest rate of the prime rate at the time plus 1%. We
must have $500 in cash, inclusive of the borrowed amount, at Libertyville on the date of any advance. Advances may only occur
at the beginning or end of a fiscal quarter and must be repaid in full within five business days of the advance. Amounts due under
the Line of Credit Agreement must be paid in full on April 4, 2020.</FONT></P>

November 16, 2018, we entered into a Business Loan Agreement (the &ldquo;Master Agreement&rdquo;) with Beachcorp, LLC. Beachcorp,
LLC is managed by Bradford T. Whitmore, who, together with his affiliates Grace Brothers, Ltd. and Grace Investments, Ltd., beneficially
owned approximately 63% of the outstanding shares of our common stock as of March 25, 2020. The Master Agreement relates to two
loan facilities, each evidenced by separate promissory notes, each dated November 16, 2018: a term loan to the Company of up to
$500 to be disbursed in a single advance (the &ldquo;Term Loan&rdquo;) with a fixed annual interest rate of 8.25%, payable quarterly,
accruing from the date of such advance and with principal due on December 31, 2020; and an asset-based revolving loan facility
for the Company of up to $2,000 (the &ldquo;Revolver Facility&rdquo;), with floating interest accruing at the prime rate plus
3% (8.25% minimum) per year, with a borrowing base consisting of qualified accounts receivable of the Company, and with all principal
and accrued interest due March 31, 2020. On March 23, 2020, the Company and Beachcorp, LLC executed the First Amendment to our
Master Agreement that extends the maturities of both the Term Loan and the Revolver Facility to March 31, 2021. The Term Loan
and Revolver Facility are secured by all the unencumbered assets of the Company and subordinated to Libertyville&rsquo;s secured
interest under the New Business Loan Agreement. The Master Agreement substantially restricts the Company&rsquo;s ability to incur
additional indebtedness during the terms of both the Term Loan and the Revolver Facility.</FONT></P>

November 20, 2019, we entered into a 2% Secured Convertible Promissory Note with Bradford T. Whitmore in the principal amount
of $2,000,000 (the &ldquo;Convertible Note&rdquo;). The principal amount is payable in a single payment on May 15, 2024 (the &ldquo;Maturity
Date&rdquo;). The principal amount of the Convertible Note accrues interest at the rate of 2.0% per year, which interest is payable
semi-annually on the 15th day of May and November, commencing on May 15, 2020. The principal amount and, at the holder&rsquo;s
option, accrued interest under the Convertible Note is convertible at the holder&rsquo;s option into additional shares of the
Company&rsquo;s common stock in whole or in part and from time to time up to the Maturity Date at a conversion price of $0.20
per share. The convertible note contains a beneficial conversion feature since the Company&rsquo;s stock was trading at $0.32
per share on the date the Company entered into the agreement. The intrinsic value of the beneficial conversion feature was $1.2
million on November 20, 2019 and is recorded as a discount on the convertible note. The discount will be accreted to the convertible
note over the life of the note using the straight-line method. The balance on the convertible note was $830, net of a discount
of $1,170 at December 31, 2019.</FONT></P>

December 31, 2019, the balance on the term loan was $500, the balance on the Revolver Facility was $224, and the balance on the
Convertible Note was $2,000. In 2019 there was $116 in interest expense relating to these credit facilities held by Beachcorp,
LLC and Bradford T. Whitmore. The accrued interest expense balance on these related party credit facilities amounted to $4, and
$7, at December 31, 2019 and December 31, 2018, respectively. The obligations under the Convertible Note are secured by a security
interest in all of the Company&rsquo;s personal property pursuant to a Commercial Security Agreement among Mr. Whitmore, the Company
and Sol&eacute;sence, LLC, the Company&rsquo;s sole subsidiary. Given that Beachcorp, LLC is an affiliate of Mr. Whitmore, this
amounts to all of this interest being owed to a related party.</FONT></P>

evaluates the renewal and termination options and when they are reasonably certain of exercise, includes the renewal or termination
option in our lease term. </FONT></P>

adoption of Topic 842 resulted in the Company recognizing operating lease liabilities totaling $2,556 with a corresponding right-of-use
(&ldquo;ROU&rdquo;) asset of $2,212 based on the present value of the minimum rental payments of such leases. The variance between
the ROU asset balance and the lease liability is deferred rent liability that existed prior to the adoption of the ASC 842 and
was offset against the ROU asset balance during the adoption. As of December 31, 2019, the ROU asset had a balance of $2,119 which
is included in the &ldquo;Operating lease right-of-use assets&rdquo; line item of these consolidated financial statements and
current and non-current lease liabilities related to the ROU asset of $357 and $2,035, respectively, and are included in the &ldquo;Current
portion of operating lease obligations&rdquo; and &ldquo;Long-term portion of operating lease obligations&rdquo; line items of
these consolidated financial statements. The discount rates used for leases accounted for under ASC 842 are based on an interest
rate yield curve developed for the leases in the Company&rsquo;s portfolio.</FONT></P>

office leases contain variable lease payments which consist primarily of rent escalations based on an established index or rate
and taxes, insurance, and common area or other maintenance costs, which are paid based on actual costs incurred by the lessor.
The Company has elected to utilize the available practical expedient to not separate lease and non-lease components.</FONT></P>

valuation allowance decreased approximately $1.1 million and $1.1 million for the years ended December 31, 2019 and 2018, respectively
(net of approximately $1.5 million and $1.6 million for the years ended December 31, 2019 and 2018, respectively, for expiring
net operating loss carryforwards and credits) due principally to the change in the net operating loss carryforward and uncertainty
as to whether future taxable income will be generated prior to the expiration of the carryforward period. Management believes
that significant uncertainty exists surrounding the recoverability of deferred tax assets due to our recurring losses. &nbsp;As
a result, the Company has recorded a full valuation allowance against our net deferred tax assets. Under the Internal Revenue
Code, certain ownership changes, including the prior issuance of preferred stock and our public offering of common stock, may
subject us to annual limitations on the utilization of our net operating loss carryforward. As of December 31, 2019, the amounts
subject to limitations have not yet been determined.</FONT></P>

use the Black&minus;Scholes option pricing model to determine the fair value of stock-based compensation. The Black&minus;Scholes
model requires us to make several assumptions, including the estimated length of time employees will retain their vested stock
options before exercising them (&ldquo;expected term&rdquo;), the estimated volatility of our common stock price over the expected
term and estimated forfeitures. Expected price volatility of the fiscal 2019 and 2018 grants is based on the daily market rate
changes of our stock going back to January 1, 2012. The shares granted in fiscal 2019 and 2018 had a vesting period of three years
and a contractual life of 10 years. Forfeitures were estimated at 2% for the years ended December 31, 2019 and 2018, based on
our historical experience. The Black&minus;Scholes model also requires a risk-free interest rate, which is based on the U.S. Treasury
yield curve in effect at the time of the grant, and the dividend yield on our common stock, which is assumed to be zero since
we do not pay dividends and have no current plans to do so in the future. Changes in these assumptions can materially affect the
estimate of fair value of stock-based compensation and consequently, the related expense recognized on the statement of operations.
We recognize stock-based compensation expense on a straight-line basis.</FONT></P>

currently have exclusive supply agreements with BASF Corporation (&ldquo;BASF&rdquo;), our largest customer, that have contingencies
outlined which could potentially result in the license of technology and/or the sale of production equipment from the Company
to the customer intended to provide capacity sufficient to meet the customer&rsquo;s production needs. This outcome may occur
if we fail to meet certain performance requirements, certain other obligations and/or certain financial condition covenants. The
financial condition covenants in one of our supply agreements with BASF &ldquo;trigger&rdquo; a technology transfer right (license
and equipment sale at BASF&rsquo;s option) in the event (a) that earnings for the twelve-month period ending with our most recently
published quarterly financial statements are less than zero and our cash, cash equivalents and certain investments are less than
$500,000, or (b) of an acceleration of any debt maturity having a principal amount of more than $10 million. There are certain
minimum finished goods inventory requirements with the new amendment to the supply agreement. This agreement also requires Nanophase
to maintain certain finished goods inventory levels as &ldquo;safety stock,&rdquo; beginning in the first quarter of 2019, and
increasing through the third quarter of 2019 to a negotiated level based on agreed demand metrics, in order to maintain the $500,000
non-cash component discussed above. After September 30, 2019, should our safety stock fall below the prescribed amount of material,
the quarter-end cash requirement would revert to $1,000,000 in cash, cash equivalents, and certain investments. The safety stock
requirement may be adjusted upon mutual agreement. The Company met its safety stock requirements at December 31, 2019.</FONT></P>

supply agreements with BASF also &ldquo;trigger&rdquo; a technology transfer right in the event of our insolvency, as further
defined within the agreements. In the event of an equipment sale, upon incurring a triggering event, the equipment would be sold
to the customer at either 115% of the equipment&rsquo;s net book value or the greater of 30% of the original book value of such
equipment, and any associated upgrades to it, or 115% of the equipment&rsquo;s net book value, depending on the equipment and

believe that cash from operations and cash on hand, in addition to unused borrowing capacity, may not be adequate to fund our
operating plans through 2020. If a triggering event were to occur and BASF elected to proceed with the license and related equipment
sale mentioned above, we would receive royalty payments from this customer for products sold using our technology; however, we
would lose both significant revenue and the ability to generate significant revenue to replace that which was lost in the near
term. Replacement of necessary equipment that could be purchased and removed by the customer pursuant to this triggering event
could take in excess of twelve months. Any additional capital outlays required to rebuild capacity would probably be greater than
the proceeds from the purchase of the assets as dictated by our agreement with the customer. Similar consequences would occur
if we were determined to have materially breached certain other provisions of the supply agreement with BASF. Any such event would
also likely result in the loss of many of our key staff and line employees due to economic realities. We believe that our employees
are a critical component of our success and it could be difficult to replace them quickly. Given the occurrence of any such event,
we might not be able to hire and retain skilled employees given the stigma relating to such an event and its impact on us. Finally,
any shortfall in capital needed to operate the business as management intends, including with respect to avoiding this triggering
event as described above, may result in a curtailment of certain activities or anticipated investments.</FONT></P>

expect to expend resources on research, development and product testing, and in expanding current capacity or capability for new

decrease in revenue from one or more of our customers or because of currently unknown capital requirements, new regulatory requirements
or the need to meet the cash requirements discussed above to avoid a triggering event under our BASF agreement. Given our expected
growth in our Sol&eacute;sence<SUP>&reg;</SUP> business, we may also have temporary working capital demands that we cannot fund
with existing capital, while remaining in compliance with the covenants included in our BASF agreement described above. In the
likely event that we will need to seek additional financing, we may seek funding through public or private financing and through
contracts with governmental entities or other companies. Additional financing may not be available on acceptable terms or at all,
and any such additional financing could be dilutive to our shareholders. If we are unable to obtain adequate funds, we may be
required to delay, scale-back or eliminate some of our manufacturing and marketing operations or we may need to obtain funds through
arrangements on less favorable terms. Such circumstances could raise doubt as to our ability to continue as a going concern. If
we obtain funding on unfavorable terms, we may be required to relinquish rights to some of our intellectual property.</FONT></P>

March 11, 2020, the World Health Organization declared the outbreak of a novel&nbsp;coronavirus&nbsp;(SARS-CoV-2) to be a global
pandemic (COVID-19), which continues to spread throughout the United States and around the world. On March 20, 2020, the Governor
of the State of Illinois ordered that all non-essential businesses cease all activities within the State of Illinois except for
certain minimum basic operations until April 7, 2020. &nbsp;During this disruption, we are doing everything we can to allow as
many of our employees as possible to shelter-in-place. Relative to the executive order in Illinois, management believes that Nanophase
Technologies and its Sol&eacute;sence subsidiary qualify as essential businesses as defined, due to our product offerings supporting
healthcare, and critical manufacturing and chemical products within sectors that have been designated as critical infrastructure,
the continued operation of which is vital for national public health, economic security, and safety.</FONT></P>

Company believes that its customers and suppliers may have similar disruptions, which may lead to greater reductions in their
normal operations as a result of responses to the coronavirus pandemic in Illinois and in other jurisdictions in the United States
and worldwide.&nbsp; As of March 25, 2020, the Company is consequently aware of changes in its business as a result of the coronavirus
pandemic, but uncertain of the impacts of those changes on its consolidated statements of position, operations or cash flows.
&nbsp;The Company&rsquo;s management believes the resulting cessations, reductions, and disruptions in its customers&rsquo; and
suppliers&rsquo; operations could be temporary; however, the Company&rsquo;s management also believes the duration and, hence,
the potential impact of such cessations, reductions, and disruptions is currently unknowable. &nbsp;As a result, we are unable
to estimate the potential impact on our business as of the date of this filing.</FONT></P>

Our expertise in nanoscale engineering allows us to effectively coat and disperse particles on a nano and&#13;&amp;#8220;non-nano&amp;#8221; scale for use in a variety of diverse markets: personal care ingredients, including sunscreens as active&#13;ingredients; full formulations of skin care products, marketed and sold by our wholly-owned subsidiary, Solesence, LLC (our &amp;#8220;Sol&amp;#233;sence&lt;sup&gt;&amp;#174;&lt;/sup&gt;&#13;subsidiary&amp;#8221;), which comprise two of our three major product categories; and in architectural coatings, industrial coating&#13;applications, abrasion-resistant additives, plastics additives, medical diagnostics, energy (including solar control) and a variety&#13;of surface finishing technologies (polishing) applications, including optics &amp;#8212; all of which fall in to the advanced materials&#13;product category.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We target markets in which&#13;we believe practical solutions may be found using our products. We work closely with current and potential customers in these target&#13;markets to identify their material and performance requirements and market our materials to various end-use applications manufacturers,&#13;and our Sol&amp;#233;sence&lt;sup&gt;&amp;#174;&lt;/sup&gt; products to cosmetics and skin care brands. Recently developed technologies have made certain&#13;new products possible and opened potential new markets. During 2015 we were granted a patent on a new type of particle surface&#13;treatment (coating) &amp;#8212; now called Active Stress Defense &amp;#8482; Technology &amp;#8212; which became the cornerstone of our new&#13;product development in personal care, with first revenue recognized during 2016. In addition, through the creation of our Sol&amp;#233;sence&lt;sup&gt;&amp;#174;&lt;/sup&gt;&#13;subsidiary, we utilize this particle surface treatment to manufacture and sell fully developed solutions to targeted customers&#13;in the skin care industry, in addition to the ingredients we have traditionally sold in the personal care area.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Although our primary strategic&#13;focus has been the North American market, we currently sell material to customers overseas and have been working to expand our&#13;reach within foreign markets.

Actual results could differ from those estimates. Certain assumptions are also necessary to assess the impact of risks and&#13;uncertainties on the financial statements, such as cash flow projections, availability of capital if needed to support the ongoing&#13;operations of the business, and our expected compliance with contractual commitments. These risks and uncertainties are further&#13;discussed in Note 13.

Whitmore, and our Term Loan and Revolving&#13;Line of Credit, both of which are facilitated by Beachcorp, LLC. Our ability to access cash from our credit facility solely depends&#13;on carrying an Accounts Receivable balance greater than the outstanding loan balance in the Revolving Line of Credit. As part of&#13;the agreement, we are required to have a bank account in place to act as a depository account for our customers. This account is&#13;referred to as the Control Account. Furthermore, there is an Account Control Agreement in place which provides Beachcorp, LLC the&#13;ability to exercise control over the account via approval of requested transfers. According to our agreements with Beachcorp, LLC,&#13;Nanophase is to be the party initiating any transfers, whether to Nanophase or to Beachcorp, LLC, and approval to access any monies&#13;within this account can only be withheld by Beachcorp, LLC if the borrowing base falls below the Company&amp;#8217;s qualified receivables,&#13;or if we are in arrears with respect to interest payments due Beachcorp, LLC. The failure of Nanophase to remedy the previously&#13;mentioned conditions could lead to Beachcorp, LLC gaining the right, through a &amp;#8220;springing&amp;#8221; feature administered by&#13;Libertyville Bank and Trust, a Wintrust Community Bank (&amp;#8220;Libertyville&amp;#8221;), to transfer funds to itself without direct&#13;approval from Nanophase. Due to the restrictive nature on this account to Nanophase Technologies Corporation, any balance in the&#13;account constitutes restricted cash. The restricted cash balance in this account on December 31, 2019 was zero.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Trade Accounts Receivable&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Trade accounts receivable&#13;are carried at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts&#13;on a monthly basis. We determine the allowance for doubtful accounts by identifying troubled accounts and by using historical experience&#13;applied to an aging of accounts. Trade accounts receivable are written off when deemed uncollectible. Recoveries of trade accounts&#13;receivable previously written off are recorded when received. Our typical credit terms are between thirty and sixty days from shipment&#13;and invoicing.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Inventories&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Inventories are stated&#13;at the lower of cost, maintained on a first in, first out basis, or net realizable value.

Depreciation expense for leased assets is included with depreciation expense for owned assets. From&#13;time to time we have self-constructed assets.

If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is&#13;measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis&#13;or appraisals. Based upon our analysis, there were no impairment charges recognized in either period presented.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Deferred Revenue&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;The Company records deferred revenue for development&#13;projects due to the contractual billing of these projects not always aligning with revenue recognition. In addition, it is now&#13;the Company&amp;#8217;s policy to require deposits relating to the production of our Sol&amp;#233;sence products.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Asset Retirement Obligations&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;In connection with our&#13;leased facilities, we are required to remove certain leasehold improvements upon termination of our occupancy. We follow the provisions&#13;of the FASB issued ASC 410-20, &lt;i&gt;Asset Retirement Obligations&lt;/i&gt;, under which we recognize a liability for the fair value of&#13;these asset retirement obligations. The fair value of that liability is measured based on an expected cash flow approach and accretion&#13;expense is recognized each period to recognize increases to the fair value of the liability due to the passage of time. Increases&#13;to the fair value of the liability, except for accretion, are added to the carrying value of the long-lived asset. Those increases&#13;are then reported in amortization expense over the estimated useful life of the long-lived asset.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0;

The fair value framework requires the categorization of assets and liabilities&#13;into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable&#13;measure of fair value, whereas Level 3 generally requires significant management judgment.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Our financial instruments&#13;include cash and cash equivalents, accounts receivable, accounts payable and accrued expenses, along with the promissory note with&#13;no related borrowings described in Note 4, any borrowings on the working capital line of credit from Libertyville Bank and Trust,&#13;and any borrowings on the working capital line of credit, along with the term loan from Beachcorp, LLC, and the promissory note&#13;payable associated with the convertible loan described in Note 4.

Based on our&#13;contract evaluation, we determined that there was no need to record any changes to our opening retained earnings due to the impact&#13;of our adoption of Topic 606. The adoption of Topic 606 did not have a material impact on our consolidated condensed financial&#13;statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Revenues are recognized&#13;at a point in time, typically when control of the promised goods is transferred to customers, in an amount that reflects the consideration&#13;we expect to receive in exchange for those goods.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We generally expense sales&#13;commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling,&#13;general and administrative expenses. Customers&amp;#8217; deposits, deferred revenue and other receipts are deferred and recognized&#13;when the revenue is realized and earned. Cash payments to customers are classified as reductions of revenue in our statements of&#13;operations.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We do not disclose the&#13;value of the unsatisfied performance obligations for contracts with an original expected length of one year or less or contracts&#13;for which we recognize revenue that we have the right to invoice for goods completed.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Other Revenue&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Other revenue may include&#13;revenue from technology license fees and paid development projects. Technology license fees and paid development projects are recognized&#13;when the obligation under the agreed upon contractual arrangement is performed on our part. We recognized a $211,000 one-time buy&#13;out of bulk material by a Solesence customer and a $289,000 one-time contractual capacity adjustment fee from our largest customer&#13;in 2019. We recognized a one-time technology development fee of $20,000 in 2018 relating to our agreement with Colorescience.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;On July 31, 2019, we entered&#13;into a Joint Development Agreement, with an initial term of ten years, with Sumitomo Corporation of Americas (&amp;#8220;SCOA&amp;#8221;)&#13;to jointly develop certain coated materials for the use in the personal care market. In return for the Company&amp;#8217;s exclusive&#13;efforts on SCOA&amp;#8217;s behalf, SCOA has paid a commitment fee of $250 and will pay two subsequent payments, of $125 each, for&#13;the development of products. The two subsequent payments are contingent upon the achievement of certain performance obligations&#13;as defined in the agreement. We began recognizing revenue recognizing revenue from the commitment fee in November 2019 and will&#13;continue to do so as we fulfill our contractual performance obligations. The Company is recognizing revenue over time using an&#13;input method.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Shipping and handling costs&#13;are included in other revenue when products are shipped and invoiced to the customer.

As such, deferred income taxes reflect the net tax effects of temporary differences between the carrying&#13;amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets&#13;and liabilities are calculated using the enacted tax rates and laws that are expected to be in effect when the anticipated reversal&#13;of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management,&#13;it is more likely than not that some or all of the deferred tax assets will not be realized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;When tax returns are filed,&#13;it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are&#13;subject to uncertainty about merits of the position taken or the amount of the position that would be ultimately sustained. The&#13;benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence,&#13;management believes it is more likely than not that the position will be sustained upon examination, including the resolution of&#13;appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that&#13;meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent&#13;likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax&#13;positions taken that exceeds the amount measured, as described above, is reflected as a liability for uncertain tax benefits in&#13;the accompanying balance sheets along with any associated interest and penalties that would be payable to the taxing authorities&#13;upon examination.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We have not recorded a&#13;reserve for any tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the&#13;timing of such deductibility. We file tax returns in all appropriate jurisdictions, which includes a federal tax return and Illinois&#13;state tax return. When and if applicable, potential interest and penalty costs are accrued as incurred, with expenses recognized&#13;in selling, general and administrative expenses in the statements of operations. As of December 31, 2019, and 2018, we had no liability&#13;for unrecognized tax benefits.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Earnings Per Share&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Options to purchase approximately&#13;243,000 shares of common stock that were outstanding as of December 31, 2019 were not included in the computation of earnings per&#13;share for the year ended December 31, 2019, as the impact of such shares are anti-dilutive. Options to purchase approximately 839,000&#13;shares of common stock that were outstanding as of December 31, 2018 were not included in the computation of earnings per share&#13;for the year ended December 31, 2018, as the impact of such shares are anti-dilutive.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;New&#13;Accounting Pronouncements &lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; text-indent: 0.5in; margin: 0"&gt;On January 1, 2019, the Company adopted Accounting Standards Update ("ASU") No. 2016-02, Leases,&#13;ASU No. 2018-10, Codification Improvements to Topic 842 (Leases) and ASU No. 2018-11, Targeted Improvements to Topic 842 (Leases).&#13;The guidance is intended to increase transparency and comparability among companies for leasing transactions, including&#13;a requirement for companies that lease assets to recognize on their balance sheets the assets and liabilities for the rights and&#13;obligations created by those leases. The guidance also provides for disclosures that allow the users of financial statements to&#13;assess the amount, timing, and uncertainty of cash flows arising from leases.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;The&#13;Company adopted the guidance on January 1, 2019 using the modified retrospective method without restatement of comparative periods.&#13;As such, periods prior to the date of adoption are presented in accordance with ASC 840 - Leases. The Company utilized the available&#13;practical expedient that allowed for the Company to not reassess whether existing contracts contain a lease under the new&#13;definition of a lease, lease classification for existing leases and whether previously capitalized initial direct costs would qualify&#13;for capitalization under the new guidance.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;The adoption of this guidance had a material&#13;impact on the Consolidated Balance Sheet as of December 31, 2019 due to the recognition of equal right-of-use assets and lease&#13;liabilities for the Company's portfolio of operating leases. The right-of-use asset balance was then adjusted by the reclassification&#13;of pre-existing accrued rent balances from other line items within the Consolidated Balance Sheet. The adoption had an immaterial&#13;impact to the Consolidated Statement of Cash Flows and to the Consolidated Statement of Operations for the year ended December&#13;31, 2019. The adoption had no impact to the Consolidated Statement of Changes in Stockholders' Equity for the year ended December&#13;31, 2019. Additional information and disclosures required by the new standard are contained in Note 7, Lease Commitments.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

We are working to reduce these risks, but some of this is dependent on several things over which we have limited control.&#13;Our largest customer made up 63% of our 2019 revenue, and expects a reduction in orders from us in 2020, which has limited our&#13;flexibility and required us to make cash management a top priority. We have seen an increase in sales of our Sol&amp;#233;sence&lt;sup&gt;&amp;#174;&#13;&lt;/sup&gt;products in late 2019, which we expect to continue, but to a greater extent, in 2020. This may require additional investment&#13;in working capital. Given these issues, and other commercial realities, we are monitoring the additional working capital demands&#13;that this could create as we continue to execute on our Sol&amp;#233;sence&lt;sup&gt;&amp;#174;&lt;/sup&gt; growth strategy. The timing of cash flows&#13;is critical. If cash generated from operations is not materially consistent with our plans, we believe that we may need to seek&#13;additional funding to address working capital demands. This uncertainty has caused us to be unable to assert that, for the next&#13;twelve months, we have enough current cash and guaranteed access to financing to fund operations, and to continue with our current&#13;growth strategy in terms of investment in capital equipment and in operating expenses related to Solesence&lt;sup&gt;&amp;#174;&lt;/sup&gt;, without&#13;securing additional financing.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;These circumstances raise&#13;significant doubt as to the Company&amp;#8217;s ability to operate as a going concern under U.S. GAAP. The accompanying financial statements&#13;have been prepared on a going concern basis in accordance with U.S. GAAP. As such, no adjustments have been made to the consolidated&#13;financial statements for the recoverability of assets and classification of liabilities that might be necessary should the Company&#13;be unable to continue operating as a going concern.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We believe that we will&#13;be able to secure additional financing if needed, but we do not have any additional financing commitments in place as of today.&#13;However, we may not be able to secure additional financing in a timely manner under commercially reasonable terms, or at all.&#13;If we are unable to secure additional financing, the operations of the Company might need to be curtailed to a certain degree,&#13;and we would need to delay capital expenditures related to our Sol&amp;#233;sence&lt;sup&gt;&amp;#174;&lt;/sup&gt; growth strategy, which could impede&#13;growth in 2020 and 2021.&lt;/p&gt;</us-gaap:SubstantialDoubtAboutGoingConcernTextBlock>

No borrowings have been incurred under this promissory note. Should any borrowings occur in the future,&#13;the interest rate would be the prime rate plus 1%, with the bank having the right to &amp;#8220;set off&amp;#8221; or apply unpaid balances&#13;against our checking account if we fail to meet our obligations under any borrowings under the note. It is our intention to renew&#13;this note annually, for as long as we need to do so pursuant to the terms of our facility lease agreement. Because there were no&#13;amounts outstanding on the note at any time during 2019 or 2018, we have recorded no related liability on our balance sheet.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We maintained a Line of&#13;Credit Agreement with Libertyville Bank and Trust Company, a Wintrust Community Bank (&amp;#8220;Libertyville&amp;#8221;), our primary&#13;bank during 2018 which had a maturity date of March 4, 2019. There were no borrowings on this line at December 31, 2018. On March&#13;22, 2019, we executed a New Business Loan Agreement with Libertyville, which replaced the maturing Line of Credit Agreement with&#13;Libertyville. Under the New Business Loan Agreement, Libertyville will provide a maximum of (i) $500 or (ii) two times the sum&#13;of (a) 75% our eligible accounts receivables and (b) our cash deposited with Libertyville, whichever is less, of revolving credit&#13;to us, collateralized by a senior priority lien on our accounts receivable, inventory, equipment, general intangibles and fixtures.&#13;Interest is payable monthly on any advances at a floating interest rate of the prime rate at the time plus 1%. We must have $500&#13;in cash, inclusive of the borrowed amount, at Libertyville on the date of any advance. Advances may only occur at the beginning&#13;or end of a fiscal quarter and must be repaid in full within five business days of the advance. Amounts due under the Line of Credit&#13;Agreement must be paid in full on April 4, 2020.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;On November 16, 2018, we&#13;entered into a Business Loan Agreement (the &amp;#8220;Master Agreement&amp;#8221;) with Beachcorp, LLC.

The Master Agreement relates to two loan facilities, each&#13;evidenced by separate promissory notes, each dated November 16, 2018: a term loan to the Company of up to $500 to be disbursed&#13;in a single advance (the &amp;#8220;Term Loan&amp;#8221;) with a fixed annual interest rate of 8.25%, payable quarterly, accruing from&#13;the date of such advance and with principal due on December 31, 2020; and an asset-based revolving loan facility for the Company&#13;of up to $2,000 (the &amp;#8220;Revolver Facility&amp;#8221;), with floating interest accruing at the prime rate plus 3% (8.25% minimum)&#13;per year, with a borrowing base consisting of qualified accounts receivable of the Company, and with all principal and accrued&#13;interest due March 31, 2020. On March 23, 2020, the Company and Beachcorp, LLC executed the First Amendment to our Master Agreement&#13;that extends the maturities of both the Term Loan and the Revolver Facility to March 31, 2021. The Term Loan and Revolver Facility&#13;are secured by all the unencumbered assets of the Company and subordinated to Libertyville&amp;#8217;s secured interest under the New&#13;Business Loan Agreement. The Master Agreement substantially restricts the Company&amp;#8217;s ability to incur additional indebtedness&#13;during the terms of both the Term Loan and the Revolver Facility.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 0.5in; margin: 0"&gt;On November 20, 2019, we entered into a 2% Secured Convertible Promissory&#13;Note with Bradford T. Whitmore in the principal amount of $2,000,000 (the &amp;#8220;Convertible Note&amp;#8221;). The principal amount&#13;is payable in a single payment on May 15, 2024 (the &amp;#8220;Maturity Date&amp;#8221;). The principal amount of the Convertible Note&#13;accrues interest at the rate of 2.0% per year, which interest is payable semi-annually on the 15th day of May and November, commencing&#13;on May 15, 2020. The principal amount and, at the holder&amp;#8217;s option, accrued interest under the Convertible Note is convertible&#13;at the holder&amp;#8217;s option into additional shares of the Company&amp;#8217;s common stock in whole or in part and from time to time&#13;up to the Maturity Date at a conversion price of $0.20 per share. The convertible note contains a beneficial conversion feature&#13;since the Company&amp;#8217;s stock was trading at $0.32 per share on the date the Company entered into the agreement. The intrinsic&#13;value of the beneficial conversion feature was $1.2 million on November 20, 2019 and is recorded as a discount on the convertible&#13;note. The discount will be accreted to the convertible note over the life of the note using the straight-line method. The balance&#13;on the convertible note was $830, net of a discount of $1,170 at December 31, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 0.5in; margin: 0"&gt;On December 31, 2019, the balance on the term loan was $500, the&#13;balance on the Revolver Facility was $224, and the balance on the Convertible Note was $2,000. In 2019 there was $116 in interest&#13;expense relating to these credit facilities held by Beachcorp, LLC and Bradford T. Whitmore. The accrued interest expense balance&#13;on these related party credit facilities amounted to $4, and $7, at December 31, 2019 and December 31, 2018, respectively. The&#13;obligations under the Convertible Note are secured by a security interest in all of the Company&amp;#8217;s personal property pursuant&#13;to a Commercial Security Agreement among Mr. Whitmore, the Company and Sol&amp;#233;sence, LLC, the Company&amp;#8217;s sole subsidiary.&#13;Given that Beachcorp, LLC is an affiliate of Mr. Whitmore, this amounts to all of this interest being owed to a related party.&lt;/p&gt;</us-gaap:DebtDisclosureTextBlock>

The Black&amp;#8722;Scholes model requires us to make&#13;several assumptions, including the estimated length of time employees will retain their vested stock options before exercising&#13;them (&amp;#8220;expected term&amp;#8221;), the estimated volatility of our common stock price over the expected term and estimated forfeitures.&#13;Expected price volatility of the fiscal 2019 and 2018 grants is based on the daily market rate changes of our stock going back&#13;to January 1, 2012. The shares granted in fiscal 2019 and 2018 had a vesting period of three years and a contractual life of 10&#13;years. Forfeitures were estimated at 2% for the years ended December 31, 2019 and 2018, based on our historical experience. The&#13;Black&amp;#8722;Scholes model also requires a risk-free interest rate, which is based on the U.S. Treasury yield curve in effect at&#13;the time of the grant, and the dividend yield on our common stock, which is assumed to be zero since we do not pay dividends and&#13;have no current plans to do so in the future. Changes in these assumptions can materially affect the estimate of fair value of&#13;stock-based compensation and consequently, the related expense recognized on the statement of operations. We recognize stock-based&#13;compensation expense on a straight-line basis.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

This outcome may occur if we fail to meet&#13;certain performance requirements, certain other obligations and/or certain financial condition covenants. The financial condition&#13;covenants in one of our supply agreements with BASF &amp;#8220;trigger&amp;#8221; a technology transfer right (license and equipment sale&#13;at BASF&amp;#8217;s option) in the event (a) that earnings for the twelve-month period ending with our most recently published quarterly&#13;financial statements are less than zero and our cash, cash equivalents and certain investments are less than $500,000, or (b) of&#13;an acceleration of any debt maturity having a principal amount of more than $10 million. There are certain minimum finished goods&#13;inventory requirements with the new amendment to the supply agreement. This agreement also requires Nanophase to maintain certain&#13;finished goods inventory levels as &amp;#8220;safety stock,&amp;#8221; beginning in the first quarter of 2019, and increasing through the&#13;third quarter of 2019 to a negotiated level based on agreed demand metrics, in order to maintain the $500,000 non-cash component&#13;discussed above. After September 30, 2019, should our safety stock fall below the prescribed amount of material, the quarter-end&#13;cash requirement would revert to $1,000,000 in cash, cash equivalents, and certain investments. The safety stock requirement may&#13;be adjusted upon mutual agreement. The Company met its safety stock requirements at December 31, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.3pt; text-align: justify; text-indent: 35.7pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Our supply agreements with&#13;BASF also &amp;#8220;trigger&amp;#8221; a technology transfer right in the event of our insolvency, as further defined within the agreements.&#13;In the event of an equipment sale, upon incurring a triggering event, the equipment would be sold to the customer at either 115%&#13;of the equipment&amp;#8217;s net book value or the greater of 30% of the original book value of such equipment, and any associated&#13;upgrades to it, or 115% of the equipment&amp;#8217;s net book value, depending on the equipment and related products.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We believe that cash from&#13;operations and cash on hand, in addition to unused borrowing capacity, may not be adequate to fund our operating plans through&#13;2020. If a triggering event were to occur and BASF elected to proceed with the license and related equipment sale mentioned above,&#13;we would receive royalty payments from this customer for products sold using our technology; however, we would lose both significant&#13;revenue and the ability to generate significant revenue to replace that which was lost in the near term. Replacement of necessary&#13;equipment that could be purchased and removed by the customer pursuant to this triggering event could take in excess of twelve&#13;months. Any additional capital outlays required to rebuild capacity would probably be greater than the proceeds from the purchase&#13;of the assets as dictated by our agreement with the customer. Similar consequences would occur if we were determined to have materially&#13;breached certain other provisions of the supply agreement with BASF. Any such event would also likely result in the loss of many&#13;of our key staff and line employees due to economic realities. We believe that our employees are a critical component of our success&#13;and it could be difficult to replace them quickly. Given the occurrence of any such event, we might not be able to hire and retain&#13;skilled employees given the stigma relating to such an event and its impact on us. Finally, any shortfall in capital needed to&#13;operate the business as management intends, including with respect to avoiding this triggering event as described above, may result&#13;in a curtailment of certain activities or anticipated investments.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We expect to expend resources&#13;on research, development and product testing, and in expanding current capacity or capability for new business. In addition, we&#13;may incur significant costs in preparing, filing, prosecuting, maintaining and enforcing our patents and other proprietary rights.&#13;We may need additional financing if we were to lose an existing customer or suffer a significant decrease in revenue from one&#13;or more of our customers or because of currently unknown capital requirements, new regulatory requirements or the need to meet&#13;the cash requirements discussed above to avoid a triggering event under our BASF agreement. Given our expected growth in our Sol&amp;#233;sence&lt;sup&gt;&amp;#174;&#13;&lt;/sup&gt;business, we may also have temporary working capital demands that we cannot fund with existing capital, while remaining&#13;in compliance with the covenants included in our BASF agreement described above. In the likely event that we will need to seek&#13;additional financing, we may seek funding through public or private financing and through contracts with governmental entities&#13;or other companies. Additional financing may not be available on acceptable terms or at all, and any such additional financing&#13;could be dilutive to our shareholders. If we are unable to obtain adequate funds, we may be required to delay, scale-back or eliminate&#13;some of our manufacturing and marketing operations or we may need to obtain funds through arrangements on less favorable terms.&#13;Such circumstances could raise doubt as to our ability to continue as a going concern. If we obtain funding on unfavorable terms,&#13;we may be required to relinquish rights to some of our intellectual property.&lt;/p&gt;</us-gaap:ConcentrationRiskDisclosureTextBlock>

Whitmore, and our Term Loan and&#13;Revolving Line of Credit, both of which are facilitated by Beachcorp, LLC. Our ability to access cash from our credit facility&#13;solely depends on carrying an Accounts Receivable balance greater than the outstanding loan balance in the Revolving Line of Credit.&#13;As part of the agreement, we are required to have a bank account in place to act as a depository account for our customers. This&#13;account is referred to as the Control Account. Furthermore, there is an Account Control Agreement in place which provides Beachcorp,&#13;LLC the ability to exercise control over the account via approval of requested transfers. According to our agreements with Beachcorp,&#13;LLC, Nanophase is to be the party initiating any transfers, whether to Nanophase or to Beachcorp, LLC, and approval to access&#13;any monies within this account can only be withheld by Beachcorp, LLC if the borrowing base falls below the Company&amp;#8217;s qualified&#13;receivables, or if we are in arrears with respect to interest payments due Beachcorp, LLC. The failure of Nanophase to remedy&#13;the previously mentioned conditions could lead to Beachcorp, LLC gaining the right, through a &amp;#8220;springing&amp;#8221; feature&#13;administered by Libertyville Bank and Trust, a Wintrust Community Bank (&amp;#8220;Libertyville&amp;#8221;), to transfer funds to itself&#13;without direct approval from Nanophase.

As such, deferred income taxes reflect the net tax effects of temporary differences between the carrying&#13;amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets&#13;and liabilities are calculated using the enacted tax rates and laws that are expected to be in effect when the anticipated reversal&#13;of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management,&#13;it is more likely than not that some or all of the deferred tax assets will not be realized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;When tax returns are filed,&#13;it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are&#13;subject to uncertainty about merits of the position taken or the amount of the position that would be ultimately sustained. The&#13;benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence,&#13;management believes it is more likely than not that the position will be sustained upon examination, including the resolution of&#13;appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that&#13;meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent&#13;likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax&#13;positions taken that exceeds the amount measured, as described above, is reflected as a liability for uncertain tax benefits in&#13;the accompanying balance sheets along with any associated interest and penalties that would be payable to the taxing authorities&#13;upon examination.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We have not recorded a&#13;reserve for any tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about&#13;the timing of such deductibility. We file tax returns in all appropriate jurisdictions, which includes a federal tax return and&#13;Illinois state tax return. When and if applicable, potential interest and penalty costs are accrued as incurred, with expenses&#13;recognized in selling, general and administrative expenses in the statements of operations. As of December 31, 2019, and 2018,&#13;we had no liability for unrecognized tax benefits.&lt;/p&gt;</us-gaap:IncomeTaxPolicyTextBlock>

On March 20, 2020, the Governor&#13;of the State of Illinois ordered that all non-essential businesses cease all activities within the State of Illinois except for&#13;certain minimum basic operations until April 7, 2020. &amp;#160;During this disruption, we are doing everything we can to allow as&#13;many of our employees as possible to shelter-in-place. Relative to the executive order in Illinois, management believes that Nanophase&#13;Technologies and its Sol&amp;#233;sence subsidiary qualify as essential businesses as defined, due to our product offerings supporting&#13;healthcare, and critical manufacturing and chemical products within sectors that have been designated as critical infrastructure,&#13;the continued operation of which is vital for national public health, economic security, and safety.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Company believes that its customers and suppliers may have similar disruptions, which may lead to greater reductions in their&#13;normal operations as a result of responses to the coronavirus pandemic in Illinois and in other jurisdictions in the United States&#13;and worldwide.&amp;#160; As of March 25, 2020, the Company is consequently aware of changes in its business as a result of the coronavirus&#13;pandemic, but uncertain of the impacts of those changes on its consolidated statements of position, operations or cash flows.&#13;&amp;#160;The Company&amp;#8217;s management believes the resulting cessations, reductions, and disruptions in its customers&amp;#8217; and&#13;suppliers&amp;#8217; operations could be temporary; however, the Company&amp;#8217;s management also believes the duration and, hence,&#13;the potential impact of such cessations, reductions, and disruptions is currently unknowable. &amp;#160;As a result, we are unable&#13;to estimate the potential impact on our business as of the date of this filing.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;</us-gaap:SubsequentEventsTextBlock>

Certain of the&#13;Company's leases include one or more options to renew or terminate the lease at the Company's discretion. The Company regularly&#13;evaluates the renewal and termination options and when they are reasonably certain of exercise, includes the renewal or termination&#13;option in our lease term. &lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24pt"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;adoption of Topic 842 resulted in the Company recognizing operating lease liabilities totaling $2,556 with a corresponding right-of-use&#13;(&amp;#8220;ROU&amp;#8221;) asset of $2,212 based on the present value of the minimum rental payments of such leases. The variance between&#13;the ROU asset balance and the lease liability is deferred rent liability that existed prior to the adoption of the ASC 842 and&#13;was offset against the ROU asset balance during the adoption. As of December 31, 2019, the ROU asset had a balance of $2,119 which&#13;is included in the &amp;#8220;Operating lease right-of-use assets&amp;#8221; line item of these consolidated financial statements and&#13;current and non-current lease liabilities related to the ROU asset of $357 and $2,035, respectively, and are included in the &amp;#8220;Current&#13;portion of operating lease obligations&amp;#8221; and &amp;#8220;Long-term portion of operating lease obligations&amp;#8221; line items of&#13;these consolidated financial statements. The discount rates used for leases accounted for under ASC 842 are based on an interest&#13;rate yield curve developed for the leases in the Company&amp;#8217;s portfolio.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

    <us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock contextRef="From2019-01-01to2019-12-31">&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;New&#13;Accounting Pronouncements &lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; text-indent: 0.5in; margin: 0"&gt;On January 1, 2019, the Company adopted Accounting Standards Update ("ASU") No. 2016-02, Leases,&#13;ASU No. 2018-10, Codification Improvements to Topic 842 (Leases) and ASU No. 2018-11, Targeted Improvements to Topic 842 (Leases).&#13;The guidance is intended to increase transparency and comparability among companies for leasing transactions, including&#13;a requirement for companies that lease assets to recognize on their balance sheets the assets and liabilities for the rights and&#13;obligations created by those leases. The guidance also provides for disclosures that allow the users of financial statements to&#13;assess the amount, timing, and uncertainty of cash flows arising from leases.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;The&#13;Company adopted the guidance on January 1, 2019 using the modified retrospective method without restatement of comparative periods.&#13;As such, periods prior to the date of adoption are presented in accordance with ASC 840 - Leases. The Company utilized the available&#13;practical expedient that allowed for the Company to not reassess whether existing contracts contain a lease under the new&#13;definition of a lease, lease classification for existing leases and whether previously capitalized initial direct costs would qualify&#13;for capitalization under the new guidance.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;The adoption of this guidance had a material&#13;impact on the Consolidated Balance Sheet as of December 31, 2019 due to the recognition of equal right-of-use assets and lease&#13;liabilities for the Company's portfolio of operating leases. The right-of-use asset balance was then adjusted by the reclassification&#13;of pre-existing accrued rent balances from other line items within the Consolidated Balance Sheet. The adoption had an immaterial&#13;impact to the Consolidated Statement of Cash Flows and to the Consolidated Statement of Operations for the year ended December&#13;31, 2019. The adoption had no impact to the Consolidated Statement of Changes in Stockholders' Equity for the year ended December&#13;31, 2019. Additional information and disclosures required by the new standard are contained in Note 7, Lease Commitments.&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">The preparation of financial
statements requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates. Certain assumptions are also necessary to assess the impact of risks and
uncertainties on the financial statements, such as cash flow projections, availability of capital if needed to support the ongoing
operations of the business, and our expected compliance with contractual commitments. These risks and uncertainties are further
discussed in Note 13. Any changes in these assumptions or business plans could have a material impact on the financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">The Cash balance on December
31, 2019 consists of funds borrowed from our Convertible Promissory Note, held by Bradford T. Whitmore, and our Term Loan and Revolving
Line of Credit, both of which are facilitated by Beachcorp, LLC. Our ability to access cash from our credit facility solely depends
on carrying an Accounts Receivable balance greater than the outstanding loan balance in the Revolving Line of Credit. As part of
the agreement, we are required to have a bank account in place to act as a depository account for our customers. This account is
referred to as the Control Account. Furthermore, there is an Account Control Agreement in place which provides Beachcorp, LLC the
ability to exercise control over the account via approval of requested transfers. According to our agreements with Beachcorp, LLC,
Nanophase is to be the party initiating any transfers, whether to Nanophase or to Beachcorp, LLC, and approval to access any monies
within this account can only be withheld by Beachcorp, LLC if the borrowing base falls below the Company&#8217;s qualified receivables,
or if we are in arrears with respect to interest payments due Beachcorp, LLC. The failure of Nanophase to remedy the previously
mentioned conditions could lead to Beachcorp, LLC gaining the right, through a &#8220;springing&#8221; feature administered by
Libertyville Bank and Trust, a Wintrust Community Bank (&#8220;Libertyville&#8221;), to transfer funds to itself without direct
approval from Nanophase. Due to the restrictive nature on this account to Nanophase Technologies Corporation, any balance in the
account constitutes restricted cash. The restricted cash balance in this account on December 31, 2019 was zero.</p>

are carried at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts
on a monthly basis. We determine the allowance for doubtful accounts by identifying troubled accounts and by using historical experience
applied to an aging of accounts. Trade accounts receivable are written off when deemed uncollectible. Recoveries of trade accounts
receivable previously written off are recorded when received. Our typical credit terms are between thirty and sixty days from shipment
and invoicing.</p>

term of the lease (3-7 years). Depreciation expense for leased assets is included with depreciation expense for owned assets. From
time to time we have self-constructed assets. These assets are stated at cost plus the capitalization of labor and are depreciated
over an estimated useful life (7-10 years) using the straight-line method.</p>

for impairment whenever events or changes in circumstances indicate that the asset&#8217;s carrying amount may not be recoverable.
We conduct long-lived asset impairment analyses in accordance with ASC 360-10-15, <i>Impairment or Disposal of Long-Lived Assets</i>.
ASC 360-10-15 requires us to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent
of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash
flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is
measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis
or appraisals. Based upon our analysis, there were no impairment charges recognized in either period presented.</p>

leased facilities, we are required to remove certain leasehold improvements upon termination of our occupancy. We follow the provisions
of the FASB issued ASC 410-20, <i>Asset Retirement Obligations</i>, under which we recognize a liability for the fair value of
these asset retirement obligations. The fair value of that liability is measured based on an expected cash flow approach and accretion
expense is recognized each period to recognize increases to the fair value of the liability due to the passage of time. Increases
to the fair value of the liability, except for accretion, are added to the carrying value of the long-lived asset. Those increases
are then reported in amortization expense over the estimated useful life of the long-lived asset.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We account for income taxes
using the liability method. As such, deferred income taxes reflect the net tax effects of temporary differences between the carrying
amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets
and liabilities are calculated using the enacted tax rates and laws that are expected to be in effect when the anticipated reversal
of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management,
it is more likely than not that some or all of the deferred tax assets will not be realized.</p>

it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are
subject to uncertainty about merits of the position taken or the amount of the position that would be ultimately sustained. The
benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence,
management believes it is more likely than not that the position will be sustained upon examination, including the resolution of
appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that
meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent
likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax
positions taken that exceeds the amount measured, as described above, is reflected as a liability for uncertain tax benefits in
the accompanying balance sheets along with any associated interest and penalties that would be payable to the taxing authorities
upon examination.</p>

timing of such deductibility. We file tax returns in all appropriate jurisdictions, which includes a federal tax return and Illinois
state tax return. When and if applicable, potential interest and penalty costs are accrued as incurred, with expenses recognized
in selling, general and administrative expenses in the statements of operations. As of December 31, 2019, and 2018, we had no liability

ASU No. 2018-10, Codification Improvements to Topic 842 (Leases) and ASU No. 2018-11, Targeted Improvements to Topic 842 (Leases).
The guidance is intended to increase transparency and comparability among companies for leasing transactions, including
a requirement for companies that lease assets to recognize on their balance sheets the assets and liabilities for the rights and
obligations created by those leases. The guidance also provides for disclosures that allow the users of financial statements to
assess the amount, timing, and uncertainty of cash flows arising from leases.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">The
Company adopted the guidance on January 1, 2019 using the modified retrospective method without restatement of comparative periods.
As such, periods prior to the date of adoption are presented in accordance with ASC 840 - Leases. The Company utilized the available
practical expedient that allowed for the Company to not reassess whether existing contracts contain a lease under the new
definition of a lease, lease classification for existing leases and whether previously capitalized initial direct costs would qualify
for capitalization under the new guidance.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">The adoption of this guidance had a material
impact on the Consolidated Balance Sheet as of December 31, 2019 due to the recognition of equal right-of-use assets and lease
liabilities for the Company's portfolio of operating leases. The right-of-use asset balance was then adjusted by the reclassification
of pre-existing accrued rent balances from other line items within the Consolidated Balance Sheet. The adoption had an immaterial
impact to the Consolidated Statement of Cash Flows and to the Consolidated Statement of Operations for the year ended December
31, 2019. The adoption had no impact to the Consolidated Statement of Changes in Stockholders' Equity for the year ended December
31, 2019. Additional information and disclosures required by the new standard are contained in Note 7, Lease Commitments.</p><span></span>

March 11, 2020, the World Health Organization declared the outbreak of a novel&#160;coronavirus&#160;(SARS-CoV-2) to be a global
pandemic (COVID-19), which continues to spread throughout the United States and around the world. On March 20, 2020, the Governor
of the State of Illinois ordered that all non-essential businesses cease all activities within the State of Illinois except for
certain minimum basic operations until April 7, 2020. &#160;During this disruption, we are doing everything we can to allow as
many of our employees as possible to shelter-in-place. Relative to the executive order in Illinois, management believes that Nanophase
Technologies and its Sol&#233;sence subsidiary qualify as essential businesses as defined, due to our product offerings supporting
healthcare, and critical manufacturing and chemical products within sectors that have been designated as critical infrastructure,
the continued operation of which is vital for national public health, economic security, and safety.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><font style="font: 10pt Times New Roman, Times, Serif">The
Company believes that its customers and suppliers may have similar disruptions, which may lead to greater reductions in their
normal operations as a result of responses to the coronavirus pandemic in Illinois and in other jurisdictions in the United States
and worldwide.&#160; As of March 25, 2020, the Company is consequently aware of changes in its business as a result of the coronavirus
pandemic, but uncertain of the impacts of those changes on its consolidated statements of position, operations or cash flows.
&#160;The Company&#8217;s management believes the resulting cessations, reductions, and disruptions in its customers&#8217; and
suppliers&#8217; operations could be temporary; however, the Company&#8217;s management also believes the duration and, hence,
the potential impact of such cessations, reductions, and disruptions is currently unknowable. &#160;As a result, we are unable
to estimate the potential impact on our business as of the date of this filing.</font></p>

Company's operating lease portfolio is comprised of operating leases for office, warehouse space and equipment. Certain of the

evaluates the renewal and termination options and when they are reasonably certain of exercise, includes the renewal or termination
option in our lease term. </font></p>

adoption of Topic 842 resulted in the Company recognizing operating lease liabilities totaling $2,556 with a corresponding right-of-use
(&#8220;ROU&#8221;) asset of $2,212 based on the present value of the minimum rental payments of such leases. The variance between
the ROU asset balance and the lease liability is deferred rent liability that existed prior to the adoption of the ASC 842 and
was offset against the ROU asset balance during the adoption. As of December 31, 2019, the ROU asset had a balance of $2,119 which
is included in the &#8220;Operating lease right-of-use assets&#8221; line item of these consolidated financial statements and
current and non-current lease liabilities related to the ROU asset of $357 and $2,035, respectively, and are included in the &#8220;Current
portion of operating lease obligations&#8221; and &#8220;Long-term portion of operating lease obligations&#8221; line items of
these consolidated financial statements. The discount rates used for leases accounted for under ASC 842 are based on an interest
rate yield curve developed for the leases in the Company&#8217;s portfolio.</font></p>

office leases contain variable lease payments which consist primarily of rent escalations based on an established index or rate

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We use the Black&#8722;Scholes
option pricing model to determine the fair value of stock-based compensation. The Black&#8722;Scholes model requires us to make
several assumptions, including the estimated length of time employees will retain their vested stock options before exercising
them (&#8220;expected term&#8221;), the estimated volatility of our common stock price over the expected term and estimated forfeitures.
Expected price volatility of the fiscal 2019 and 2018 grants is based on the daily market rate changes of our stock going back
to January 1, 2012. The shares granted in fiscal 2019 and 2018 had a vesting period of three years and a contractual life of 10
years. Forfeitures were estimated at 2% for the years ended December 31, 2019 and 2018, based on our historical experience. The
Black&#8722;Scholes model also requires a risk-free interest rate, which is based on the U.S. Treasury yield curve in effect at
the time of the grant, and the dividend yield on our common stock, which is assumed to be zero since we do not pay dividends and
have no current plans to do so in the future. Changes in these assumptions can materially affect the estimate of fair value of
stock-based compensation and consequently, the related expense recognized on the statement of operations. We recognize stock-based
compensation expense on a straight-line basis.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We believe that cash from
operations and cash on hand, in addition to unused borrowing capacity, may not be adequate to fund our operating plans through
2020. We are working to reduce these risks, but some of this is dependent on several things over which we have limited control.
Our largest customer made up 63% of our 2019 revenue, and expects a reduction in orders from us in 2020, which has limited our
flexibility and required us to make cash management a top priority. We have seen an increase in sales of our Sol&#233;sence<sup>&#174;
</sup>products in late 2019, which we expect to continue, but to a greater extent, in 2020. This may require additional investment
in working capital. Given these issues, and other commercial realities, we are monitoring the additional working capital demands
that this could create as we continue to execute on our Sol&#233;sence<sup>&#174;</sup> growth strategy. The timing of cash flows
is critical. If cash generated from operations is not materially consistent with our plans, we believe that we may need to seek
additional funding to address working capital demands. This uncertainty has caused us to be unable to assert that, for the next
twelve months, we have enough current cash and guaranteed access to financing to fund operations, and to continue with our current
growth strategy in terms of investment in capital equipment and in operating expenses related to Solesence<sup>&#174;</sup>, without
securing additional financing.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">These circumstances raise
significant doubt as to the Company&#8217;s ability to operate as a going concern under U.S. GAAP. The accompanying financial statements
have been prepared on a going concern basis in accordance with U.S. GAAP. As such, no adjustments have been made to the consolidated
financial statements for the recoverability of assets and classification of liabilities that might be necessary should the Company
be unable to continue operating as a going concern.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We believe that we will
be able to secure additional financing if needed, but we do not have any additional financing commitments in place as of today.
However, we may not be able to secure additional financing in a timely manner under commercially reasonable terms, or at all.
If we are unable to secure additional financing, the operations of the Company might need to be curtailed to a certain degree,
and we would need to delay capital expenditures related to our Sol&#233;sence<sup>&#174;</sup> growth strategy, which could impede
growth in 2020 and 2021.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Nanophase Technologies
Corporation (&#8220;Nanophase,&#8221; &#8220;Company,&#8221; &#8220;we,&#8221; &#8220;our,&#8221; or &#8220;us&#8221;) is a skin
and sun care focused company that offers engineered materials, formulation development and commercial manufacturing with an integrated
family of technologies. Our expertise in nanoscale engineering allows us to effectively coat and disperse particles on a nano and
&#8220;non-nano&#8221; scale for use in a variety of diverse markets: personal care ingredients, including sunscreens as active
ingredients; full formulations of skin care products, marketed and sold by our wholly-owned subsidiary, Solesence, LLC (our &#8220;Sol&#233;sence<sup>&#174;</sup>
subsidiary&#8221;), which comprise two of our three major product categories; and in architectural coatings, industrial coating
applications, abrasion-resistant additives, plastics additives, medical diagnostics, energy (including solar control) and a variety
of surface finishing technologies (polishing) applications, including optics &#8212; all of which fall in to the advanced materials
product category.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We target markets in which
we believe practical solutions may be found using our products. We work closely with current and potential customers in these target
markets to identify their material and performance requirements and market our materials to various end-use applications manufacturers,
and our Sol&#233;sence<sup>&#174;</sup> products to cosmetics and skin care brands. Recently developed technologies have made certain
new products possible and opened potential new markets. During 2015 we were granted a patent on a new type of particle surface
treatment (coating) &#8212; now called Active Stress Defense &#8482; Technology &#8212; which became the cornerstone of our new
product development in personal care, with first revenue recognized during 2016. In addition, through the creation of our Sol&#233;sence<sup>&#174;</sup>
subsidiary, we utilize this particle surface treatment to manufacture and sell fully developed solutions to targeted customers
in the skin care industry, in addition to the ingredients we have traditionally sold in the personal care area.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Although our primary strategic
focus has been the North American market, we currently sell material to customers overseas and have been working to expand our
reach within foreign markets. The Company was incorporated in Illinois on November 25, 1989, and became a Delaware corporation
during November 1997. Our common stock trades on the OTCQB marketplace under the symbol NANX.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">While product sales comprise
the majority of our revenue, we also recognize revenue from other sources from time to time. These activities are not expected
to drive the long-term growth of the business. For this reason, we classify such revenue as &#8220;other revenue&#8221; in our
Statements of Operations, as it does not represent revenue directly from the sale of our products.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 24.5pt">The valuation allowance
decreased approximately $1.1 million and $1.1 million for the years ended December 31, 2019 and 2018, respectively (net of
approximately $1.5 million and $1.6 million for the years ended December 31, 2019 and 2018, respectively, for expiring net
operating loss carryforwards and credits) due principally to the change in the net operating loss carryforward and
uncertainty as to whether future taxable income will be generated prior to the expiration of the carryforward period.
Management believes that significant uncertainty exists surrounding the recoverability of deferred tax assets due to our
recurring losses. &#160;As a result, the Company has recorded a full valuation allowance against our net deferred tax assets.
Under the Internal Revenue Code, certain ownership changes, including the prior issuance of preferred stock and our public
offering of common stock, may subject us to annual limitations on the utilization of our net operating loss carryforward. As
of December 31, 2019, the amounts subject to limitations have not yet been determined.</p>

loss carryforwards for tax purposes of approximately $77 million on December&#160;31, 2019. $72 million expire between 2020 and
2037. All net operating loss carryforwards generated after January 1, 2018 do not expire. Therefore, $5 million in net operating
losses generated since January 1, 2018 do not expire.</p><span></span>

from two customers constituted approximately accounted for 63%, and 8%, respectively, of our 2019 revenue. Amounts included in
accounts receivable on December 31, 2019 relating to these two customers were approximately $449 and $16, respectively. Revenue
from these two customers constituted approximately 74% and 7%, respectively, of our 2018 revenue. Amounts included in accounts
receivable on December 31, 2018 relating to these two customers were approximately $316 and $74, respectively. The loss of one
of these significant customers or the failure to attract new customers could have a material adverse effect on our business, results
of operations and financial condition.&#160;&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.3pt; text-align: justify; text-indent: 35.7pt">We currently
have exclusive supply agreements with BASF Corporation (&#8220;BASF&#8221;), our largest customer, that have contingencies outlined
which could potentially result in the license of technology and/or the sale of production equipment from the Company to the customer
intended to provide capacity sufficient to meet the customer&#8217;s production needs. This outcome may occur if we fail to meet
certain performance requirements, certain other obligations and/or certain financial condition covenants. The financial condition
covenants in one of our supply agreements with BASF &#8220;trigger&#8221; a technology transfer right (license and equipment sale
at BASF&#8217;s option) in the event (a) that earnings for the twelve-month period ending with our most recently published quarterly
financial statements are less than zero and our cash, cash equivalents and certain investments are less than $500,000, or (b) of
an acceleration of any debt maturity having a principal amount of more than $10 million. There are certain minimum finished goods
inventory requirements with the new amendment to the supply agreement. This agreement also requires Nanophase to maintain certain
finished goods inventory levels as &#8220;safety stock,&#8221; beginning in the first quarter of 2019, and increasing through the
third quarter of 2019 to a negotiated level based on agreed demand metrics, in order to maintain the $500,000 non-cash component
discussed above. After September 30, 2019, should our safety stock fall below the prescribed amount of material, the quarter-end
cash requirement would revert to $1,000,000 in cash, cash equivalents, and certain investments. The safety stock requirement may
be adjusted upon mutual agreement. The Company met its safety stock requirements at December 31, 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.3pt; text-align: justify; text-indent: 35.7pt">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Our supply agreements with
BASF also &#8220;trigger&#8221; a technology transfer right in the event of our insolvency, as further defined within the agreements.
In the event of an equipment sale, upon incurring a triggering event, the equipment would be sold to the customer at either 115%
of the equipment&#8217;s net book value or the greater of 30% of the original book value of such equipment, and any associated
upgrades to it, or 115% of the equipment&#8217;s net book value, depending on the equipment and related products.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We believe that cash from
operations and cash on hand, in addition to unused borrowing capacity, may not be adequate to fund our operating plans through
2020. If a triggering event were to occur and BASF elected to proceed with the license and related equipment sale mentioned above,
we would receive royalty payments from this customer for products sold using our technology; however, we would lose both significant
revenue and the ability to generate significant revenue to replace that which was lost in the near term. Replacement of necessary
equipment that could be purchased and removed by the customer pursuant to this triggering event could take in excess of twelve
months. Any additional capital outlays required to rebuild capacity would probably be greater than the proceeds from the purchase
of the assets as dictated by our agreement with the customer. Similar consequences would occur if we were determined to have materially
breached certain other provisions of the supply agreement with BASF. Any such event would also likely result in the loss of many
of our key staff and line employees due to economic realities. We believe that our employees are a critical component of our success
and it could be difficult to replace them quickly. Given the occurrence of any such event, we might not be able to hire and retain
skilled employees given the stigma relating to such an event and its impact on us. Finally, any shortfall in capital needed to
operate the business as management intends, including with respect to avoiding this triggering event as described above, may result
in a curtailment of certain activities or anticipated investments.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We expect to expend resources
on research, development and product testing, and in expanding current capacity or capability for new business. In addition, we
may incur significant costs in preparing, filing, prosecuting, maintaining and enforcing our patents and other proprietary rights.
We may need additional financing if we were to lose an existing customer or suffer a significant decrease in revenue from one
or more of our customers or because of currently unknown capital requirements, new regulatory requirements or the need to meet
the cash requirements discussed above to avoid a triggering event under our BASF agreement. Given our expected growth in our Sol&#233;sence<sup>&#174;
</sup>business, we may also have temporary working capital demands that we cannot fund with existing capital, while remaining
in compliance with the covenants included in our BASF agreement described above. In the likely event that we will need to seek
additional financing, we may seek funding through public or private financing and through contracts with governmental entities
or other companies. Additional financing may not be available on acceptable terms or at all, and any such additional financing
could be dilutive to our shareholders. If we are unable to obtain adequate funds, we may be required to delay, scale-back or eliminate
some of our manufacturing and marketing operations or we may need to obtain funds through arrangements on less favorable terms.
Such circumstances could raise doubt as to our ability to continue as a going concern. If we obtain funding on unfavorable terms,
we may be required to relinquish rights to some of our intellectual property.</p><span></span>

<a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">- Definition</a><div><p>Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid Investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Short-term investments, exclusive of cash equivalents, generally consist of marketable securities intended to be sold within one year (or the normal operating cycle if longer) and may include trading securities, available-for-sale securities, or held-to-maturity securities (if maturing within one year), as applicable.</p></div>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">During July 2014 we entered
into a bank-issued letter of credit and related promissory note for up to $30 in borrowings to support our obligations under our
facility lease agreement. No borrowings have been incurred under this promissory note. Should any borrowings occur in the future,
the interest rate would be the prime rate plus 1%, with the bank having the right to &#8220;set off&#8221; or apply unpaid balances
against our checking account if we fail to meet our obligations under any borrowings under the note. It is our intention to renew
this note annually, for as long as we need to do so pursuant to the terms of our facility lease agreement. Because there were no
amounts outstanding on the note at any time during 2019 or 2018, we have recorded no related liability on our balance sheet.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We maintained a Line of
Credit Agreement with Libertyville Bank and Trust Company, a Wintrust Community Bank (&#8220;Libertyville&#8221;), our primary
bank during 2018 which had a maturity date of March 4, 2019. There were no borrowings on this line at December 31, 2018. On March
22, 2019, we executed a New Business Loan Agreement with Libertyville, which replaced the maturing Line of Credit Agreement with
Libertyville. Under the New Business Loan Agreement, Libertyville will provide a maximum of (i) $500 or (ii) two times the sum
of (a) 75% our eligible accounts receivables and (b) our cash deposited with Libertyville, whichever is less, of revolving credit
to us, collateralized by a senior priority lien on our accounts receivable, inventory, equipment, general intangibles and fixtures.
Interest is payable monthly on any advances at a floating interest rate of the prime rate at the time plus 1%. We must have $500
in cash, inclusive of the borrowed amount, at Libertyville on the date of any advance. Advances may only occur at the beginning
or end of a fiscal quarter and must be repaid in full within five business days of the advance. Amounts due under the Line of Credit
Agreement must be paid in full on April 4, 2020.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">On November 16, 2018, we
entered into a Business Loan Agreement (the &#8220;Master Agreement&#8221;) with Beachcorp, LLC. Beachcorp, LLC is managed by Bradford
T. Whitmore, who, together with his affiliates Grace Brothers, Ltd. and Grace Investments, Ltd., beneficially owned approximately
63% of the outstanding shares of our common stock as of March 25, 2020. The Master Agreement relates to two loan facilities, each
evidenced by separate promissory notes, each dated November 16, 2018: a term loan to the Company of up to $500 to be disbursed
in a single advance (the &#8220;Term Loan&#8221;) with a fixed annual interest rate of 8.25%, payable quarterly, accruing from
the date of such advance and with principal due on December 31, 2020; and an asset-based revolving loan facility for the Company
of up to $2,000 (the &#8220;Revolver Facility&#8221;), with floating interest accruing at the prime rate plus 3% (8.25% minimum)
per year, with a borrowing base consisting of qualified accounts receivable of the Company, and with all principal and accrued
interest due March 31, 2020. On March 23, 2020, the Company and Beachcorp, LLC executed the First Amendment to our Master Agreement
that extends the maturities of both the Term Loan and the Revolver Facility to March 31, 2021. The Term Loan and Revolver Facility
are secured by all the unencumbered assets of the Company and subordinated to Libertyville&#8217;s secured interest under the New
Business Loan Agreement. The Master Agreement substantially restricts the Company&#8217;s ability to incur additional indebtedness
during the terms of both the Term Loan and the Revolver Facility.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 0.5in; margin: 0">On November 20, 2019, we entered into a 2% Secured Convertible Promissory
Note with Bradford T. Whitmore in the principal amount of $2,000,000 (the &#8220;Convertible Note&#8221;). The principal amount
is payable in a single payment on May 15, 2024 (the &#8220;Maturity Date&#8221;). The principal amount of the Convertible Note
accrues interest at the rate of 2.0% per year, which interest is payable semi-annually on the 15th day of May and November, commencing
on May 15, 2020. The principal amount and, at the holder&#8217;s option, accrued interest under the Convertible Note is convertible
at the holder&#8217;s option into additional shares of the Company&#8217;s common stock in whole or in part and from time to time
up to the Maturity Date at a conversion price of $0.20 per share. The convertible note contains a beneficial conversion feature
since the Company&#8217;s stock was trading at $0.32 per share on the date the Company entered into the agreement. The intrinsic
value of the beneficial conversion feature was $1.2 million on November 20, 2019 and is recorded as a discount on the convertible
note. The discount will be accreted to the convertible note over the life of the note using the straight-line method. The balance
on the convertible note was $830, net of a discount of $1,170 at December 31, 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; text-indent: 0.5in; margin: 0">On December 31, 2019, the balance on the term loan was $500, the
balance on the Revolver Facility was $224, and the balance on the Convertible Note was $2,000. In 2019 there was $116 in interest
expense relating to these credit facilities held by Beachcorp, LLC and Bradford T. Whitmore. The accrued interest expense balance
on these related party credit facilities amounted to $4, and $7, at December 31, 2019 and December 31, 2018, respectively. The
obligations under the Convertible Note are secured by a security interest in all of the Company&#8217;s personal property pursuant
to a Commercial Security Agreement among Mr. Whitmore, the Company and Sol&#233;sence, LLC, the Company&#8217;s sole subsidiary.
Given that Beachcorp, LLC is an affiliate of Mr. Whitmore, this amounts to all of this interest being owed to a related party.</p><span></span>

statements requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates. Certain assumptions are also necessary to assess the impact of risks
and uncertainties on the financial statements, such as cash flow projections, availability of capital if needed to support the
ongoing operations of the business, and our expected compliance with contractual commitments. These risks and uncertainties are
further discussed in Note 13. Any changes in these assumptions or business plans could have a material impact on the financial

31, 2019 consists of funds borrowed from our Convertible Promissory Note, held by Bradford T. Whitmore, and our Term Loan and
Revolving Line of Credit, both of which are facilitated by Beachcorp, LLC. Our ability to access cash from our credit facility
solely depends on carrying an Accounts Receivable balance greater than the outstanding loan balance in the Revolving Line of Credit.
As part of the agreement, we are required to have a bank account in place to act as a depository account for our customers. This
account is referred to as the Control Account. Furthermore, there is an Account Control Agreement in place which provides Beachcorp,
LLC the ability to exercise control over the account via approval of requested transfers. According to our agreements with Beachcorp,
LLC, Nanophase is to be the party initiating any transfers, whether to Nanophase or to Beachcorp, LLC, and approval to access
any monies within this account can only be withheld by Beachcorp, LLC if the borrowing base falls below the Company&#8217;s qualified
receivables, or if we are in arrears with respect to interest payments due Beachcorp, LLC. The failure of Nanophase to remedy
the previously mentioned conditions could lead to Beachcorp, LLC gaining the right, through a &#8220;springing&#8221; feature
administered by Libertyville Bank and Trust, a Wintrust Community Bank (&#8220;Libertyville&#8221;), to transfer funds to itself
without direct approval from Nanophase. Due to the restrictive nature on this account to Nanophase Technologies Corporation, any
balance in the account constitutes restricted cash. The restricted cash balance in this account on December 31, 2019 was zero.</p><span></span>

using the liability method. As such, deferred income taxes reflect the net tax effects of temporary differences between the carrying
amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets
and liabilities are calculated using the enacted tax rates and laws that are expected to be in effect when the anticipated reversal
of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management,

it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are
subject to uncertainty about merits of the position taken or the amount of the position that would be ultimately sustained. The
benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence,
management believes it is more likely than not that the position will be sustained upon examination, including the resolution of
appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that

likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax
positions taken that exceeds the amount measured, as described above, is reflected as a liability for uncertain tax benefits in
the accompanying balance sheets along with any associated interest and penalties that would be payable to the taxing authorities
upon examination.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-indent: 0.5in; margin: 0">On January 1, 2019, the Company adopted Accounting Standards Update ("ASU") No. 2016-02, Leases,
ASU No. 2018-10, Codification Improvements to Topic 842 (Leases) and ASU No. 2018-11, Targeted Improvements to Topic 842 (Leases).
The guidance is intended to increase transparency and comparability among companies for leasing transactions, including
a requirement for companies that lease assets to recognize on their balance sheets the assets and liabilities for the rights and
obligations created by those leases. The guidance also provides for disclosures that allow the users of financial statements to
assess the amount, timing, and uncertainty of cash flows arising from leases.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">The
Company adopted the guidance on January 1, 2019 using the modified retrospective method without restatement of comparative periods.
As such, periods prior to the date of adoption are presented in accordance with ASC 840 - Leases. The Company utilized the available
practical expedient that allowed for the Company to not reassess whether existing contracts contain a lease under the new
definition of a lease, lease classification for existing leases and whether previously capitalized initial direct costs would qualify
for capitalization under the new guidance.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">The adoption of this guidance had a material
impact on the Consolidated Balance Sheet as of December 31, 2019 due to the recognition of equal right-of-use assets and lease
liabilities for the Company's portfolio of operating leases. The right-of-use asset balance was then adjusted by the reclassification
of pre-existing accrued rent balances from other line items within the Consolidated Balance Sheet. The adoption had an immaterial
impact to the Consolidated Statement of Cash Flows and to the Consolidated Statement of Operations for the year ended December
31, 2019. The adoption had no impact to the Consolidated Statement of Changes in Stockholders' Equity for the year ended December
31, 2019. Additional information and disclosures required by the new standard are contained in Note 7, Lease Commitments.</p><span></span>
