Estimates</span></b> - The preparation of financial statements in conformity with generally accepted accounting principles in the United States

of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimated by management. Significant accounting estimates that may materially
change in the near future are impairment of long-lived assets, values of stock compensation awards and stock equivalents granted as offering
costs, and allowance for bad debts and inventory obsolescence.</span></p>

June 23, 2020, the board of directors (the &#8220;Board&#8221;) of the Company adopted the Sigma Labs, Inc. 2020 Stock Appreciation Rights
Plan (the &#8220;Plan&#8221;). The purposes of the Plan are to: (i) enable the Company to attract and retain the types of employees,
consultants and directors (collectively, &#8220;Service Providers&#8221;) who will contribute to the Company&#8217;s long range success;
(ii) provide incentives that align the interests of Service Providers with those of the shareholders of the Company; and (iii) promote
the success of the Company&#8217;s business. The Plan provides for incentive awards that are only made in the form of stock appreciation
rights payable in cash (&#8220;SARs&#8221;). No shares of common stock were reserved in connection with the adoption of the Plan since
no shares will be issued pursuant to the Plan.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">SARs
may be granted to any Service Provider. A SAR is the right to receive an amount equal to the Spread with respect to a share of the Company&#8217;s
common stock (&#8220;Share&#8221;) upon the exercise of the SAR. The &#8220;Spread&#8221; is the difference between the exercise price
per share specified in a SAR agreement on the date of grant and the fair market value per share on the date of exercise of the SAR. The
exercise price per share will not be less than 100% of the fair market value of a Share on the date of grant of the SAR. The administrator
of the Plan will have the authority to, among other things, prescribe the terms and conditions of each SAR, including, without limitation,
the exercise price and medium of payment and vesting provisions, and to specify the provisions of the SAR Agreement relating to such
grant.</span></p>

preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management
to make estimates and assumptions that affect the reported amounts in the accompanying consolidated financial statements and related
notes. These estimates and assumptions have a significant impact on our consolidated financial statements. Actual results could differ
materially from those estimates. Critical accounting policies are those that require the most subjective and complex judgments, often
employing the use of estimates about the effect of matters that are inherently uncertain. Our significant accounting policies are disclosed
in Note 1 to the Financial Statements included in this Quarterly Report on Form 10-Q. However, we do not believe that there are any alternative
methods of accounting for our operations that would have a material effect on our financial statements.</span></p>

increase is primarily attributable to costs incurred in connection with the installation and support of previous PrintRite3D sales,
as well as support of current and legacy RTE&#8217;s, partially offset by a decrease in manufacturing costs of our PrintRite3D units
as a result of engineering enhancements.</span></p>

of $280,700 were incurred during the three months ended June 30, 2021 compared to $111,647 in the same period of 2020, a $169,053
increase. The increase is primarily attributable to $73,638 for CT scans related to new development work, $21,332 related to
optics redesign, $33,310 for ongoing enhancements and bug fixes related to PrintRite3D v7.0, and purchases of lab supplies, and
parts and materials of $31,771.</p>

expenses of $114,762 were incurred during the three months ended June 30, 2021, as compared to $97,702 incurred during the same period
in 2020. The increase of $17,060 is primarily due to an increase in expenses for trade shows and conferences of $26,267, partially
offset by a decrease in marketing and advertising costs of $13,655, as the Company discontinued its Network Newswire service.</p>

the three months ended June 30, 2021 totaled $158,529, as compared to $80,096 for the same period in 2020. The increase of $78,433,
or 97.9% is due to an increase in shareholder services costs of $34,109 related to the special shareholders meeting held in
May of 2021, and $60,802 related to stock options expense for non-employee directors, whereas options were not granted to
non-employee directors until July 2020. Partially offsetting these increases was a decrease in non-employee directors&#8217; cash
compensation of $17,173 in the second quarter of 2021 as compared to the same period in 2020.</p>

incurred in the three months ended June 30, 2021 were $244,019 compared to $212,496 incurred during the same period in 2020. The increase
of $31,523 is primarily due to an increase in recruiting fees of $64,000 related to new hires during the period, an increase in consulting
fees of $9,112 and an increase in IT services of $2,738, partially offset by a decrease in legal fees of $24,626, and lower accounting
and audit fees of $19,700.</p>

increase of $73,028, or 92.6%. The increase is primarily due to increased travel costs of $40,973 as a result of the easing
of COVID-19 restrictions, an increase of $15,540 in dues and subscriptions, primarily related to new software applications,
including customer relationship management, product lifecycle management, and compliance, an increase of $10,272 in postage

expense for the three months ended June 30, 2021 was $25,783, compared to $17,970 for the same period in 2020. The primary reason for
the increase is due to depreciation on lab equipment purchased for European engineers to facilitate testing and installations.</p>

$91,198 for the three months ended June 30, 2021, compared to $51,687 incurred during the same period in 2020. The increase of $39,511
is primarily due to higher insurance premiums of $32,839 in 2021. In addition, increased SEC filing fees of $4,956 related
to various registration statements were incurred in June 2021.</p>

2021 net positive contribution is primarily from a gain of $290,156 on the revaluation of the derivative liability incurred in connection with the issuance of warrants to purchase common stock in our March 2021 offering. In 2020, the
net positive contribution consisted primarily of $151,657 in New Mexico state job incentive credits, and $361,700 from
the recognition of our PPP loan as a government grant.</p>

a $258,249 increase. The second quarter net operating loss contributed $724,350 to the loss increase, while the decrease in other
income contributed an additional loss of $211,559. Partially offsetting these losses was a decrease in preferred dividends of $677,660
for the quarter ended June 30, 2021.</p>

June 30, 2021, we recognized revenue of $602,288 compared to $389,418 during the same period of 2020. The primary contributors to the
$212,870 increase were an increase in PrintRite3D&#174; unit sales contributing $276,242, partially offset by a decrease in a RTE
program revenue of $67,200.</p>

six months ended June 30, 2021 was $244,728 compared to $302,387 during the same period in 2020. The decrease of $57,659 is primarily
due to a credit in the first quarter related to a customer exchange of a PrintRite3D unit sold in December 2020, lower build costs
as a result of engineering enhancements of our PrintRite3D units, and lower costs of supporting legacy RTE programs.</p>

ended June 30, 2021 were $1,832,520 compared to $1,257,492 for the same period in 2020, an increase of $575,028. The increase is primarily
due to employee salary increases and higher average employee headcount of 7 during the first half of 2021, resulting
in increased salaries of $421,207, plus $28,270 in employee benefits and $34,202 in employer payroll taxes. Also contributing to the
increase was $26,924 in sales commissions and bonuses, and $60,615 of expense related to the Company&#8217;s Stock Appreciation

the six months ended June 30, 2021 was $233,919 compared to $424,989 for the same period in 2020, a $191,070 decrease, primarily due
to stock options granted to our CEO vesting in the first quarter of 2020 with no such vesting in the first quarter of 2021, and stock
options awarded to employees in June of 2020. With the exception of stock option grants to new employees, stock option awards were

2020. The $311,705 increase in these expenditures during the first six months of 2021 is a result of development costs incurred
in connection with PrintRite3D version 7.0 of $81,477, increased purchases of lab supplies of $97,382, of which metal powder
purchases totaled $14,161, argon gas totaled $15,434, laboratory facility upgrades totaled $8,852, and cables and cable making
supplies totaled $19,075, CT scans conducted for new development work and a simulation project totaling of $93,638, increased
write-offs of $40,350 in obsolete inventory, and $21,332 related to optics redesign. Partially offsetting these increases was a
decrease in consulting expenses of $22,926 due to the full-time hire of a consultant in 2021.</p>

six months ended June 30, 2021 totaled $236,145, as compared to $155,675 for the same period in 2020. The increase of $80,470 is primarily
due to $122,273 of stock option expense for non-employee directors in the first half of 2021 verses $0 in the first half of 2020,
as such grants were not made to non-employee directors until the second half of 2020. Partially offsetting this increase was a decrease
in non-employee director cash compensation of $22,305, and a reduction in shareholder services expenses of $19,498.</p>

with our January 2020 private offering, Nasdaq related matters, and our February 27, 2020 reverse stock split. Also contributing to the
decrease were lower accounting related expenses of $16,670. Partially offsetting these decreases was an increase in recruiting fees of
$90,667 related to ten new hires during the first half of 2021, and increased consulting fees of $45,211 related to an external marketing
consultant, and corporate consulting services, and increased IT services of $6,238.</p>

the second quarter of 2021 progressed, the Company continued to be adversely affected by the COVID-19 global economic slowdown,
which has resulted in lower revenue than anticipated. Several customers have delayed purchase orders, and although they have not been
cancelled, the timing of when they might be received continues to be uncertain. Two key industries with which we do business,
aerospace and oil and gas, have experienced a reduction in the global demand for their products due to the pandemic. We have also experienced
delays in purchase orders from universities and research institutes. As a result of the decrease in the demand for our products from
customers and potential customers in these and other industries, the Company expects that revenue from these sectors will remain
under pressure. It is impossible to know at this time how long companies will limit capital expenditures and if the industries that
have been most negatively affected will resume normal purchasing. However, due to the need to have more flexibility in supply chains
with the ability to respond quickly to shortages in parts or products, we believe that the crisis will eventually
accelerate the adoption of 3D printing, which would be a positive trend for the Company.</span></p>

of Business&lt;/span&gt;&lt;/b&gt; -Sigma Labs, Inc., formerly named Framewaves, Inc., a Nevada corporation, was founded by a group of scientists, engineers
and businessmen to develop and commercialize novel and unique manufacturing and materials technologies. Sigma believes that some of these
technologies will fundamentally redefine conventional quality assurance and process control practices by embedding them into the manufacturing
processes in real time, enabling process intervention and ultimately leading to closed loop process control. The Company anticipates
that its core technologies will allow its clientele to combine advanced manufacturing quality assurance and process control protocols
with novel materials to achieve breakthrough product potential in many industries including aerospace, defense, oil and gas, bio-medical,
and power generation. The terms the &#x201c;Company,&#x201d; &#x201c;Sigma,&#x201d; &#x201c;we,&#x201d; &#x201c;us&#x201d; and &#x201c;our&#x201d;

of Presentation&lt;/span&gt;&lt;/b&gt; - The accompanying financial statements have been prepared by the Company in accordance with Generally Accepted Accounting
Principles (&#x201c;GAAP&#x201d;) in the United States of America. In the opinion of management, all adjustments (which include only normal
recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows at June 30, 2021 and
2020 and for the periods then ended have been made. Certain information and footnote disclosures normally included in financial statements
prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. The Company suggests these
condensed financial statements be read in conjunction with the December 31, 2020 audited financial statements and notes thereto included
in the Company&#x2019;s Form 10-K. The results of operations for the periods ended June 30, 2021 and 2020 are not necessarily indicative
of the operating results for the full year.&lt;/span&gt;&lt;/p&gt;

Estimates&lt;/span&gt;&lt;/b&gt; - The preparation of financial statements in conformity with generally accepted accounting principles in the United States
requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, the disclosures
of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimated by management. Significant accounting estimates that may materially
change in the near future are impairment of long-lived assets, values of stock compensation awards and stock equivalents granted as offering
costs, and allowance for bad debts and inventory obsolescence.&lt;/span&gt;&lt;/p&gt;

recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows at June 30, 2021 and

prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. The Company suggests these
condensed financial statements be read in conjunction with the December 31, 2020 audited financial statements and notes thereto included

releases of the Securities and Exchange Commission (&#x201c;SEC&#x201d;) issued under authority of federal securities laws are also sources
of GAAP for SEC registrants.&lt;/span&gt;&lt;/p&gt;

Estimates&lt;/span&gt;&lt;/b&gt; - The preparation of financial statements in conformity with generally accepted accounting principles in the United States
requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, the disclosures
of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimated by management. Significant accounting estimates that may materially
change in the near future are impairment of long-lived assets, values of stock compensation awards and stock equivalents granted as offering
costs, and allowance for bad debts and inventory obsolescence.&lt;/span&gt;&lt;/p&gt;

March 26, 2021 (the &#x201c;Issuance Date&#x201d;), the Company issued warrants to purchase an aggregate of &lt;span id="xdx_905_eus-gaap--ClassOfWarrantOrRightNumberOfSecuritiesCalledByWarrantsOrRights_iI_pid_c20210326_ziZsCm37opBe" title="Warrants to purchase shares of common stock"&gt;2,190,000&lt;/span&gt; shares of common
stock to holders in a private placement concurrently with a registered direct offering of &lt;span id="xdx_903_eus-gaap--StockIssuedDuringPeriodSharesNewIssues_pid_c20210325__20210326_zAazEGW9vXej" title="Number of common shares issued"&gt;2,190,000&lt;/span&gt; shares of its common stock. The warrants
entitle the holders to purchase one share of our common stock at an exercise price equal to $&lt;span id="xdx_907_eus-gaap--SharesIssuedPricePerShare_iI_pid_c20210326_zx4FPWYZuMJk" title="Share price per share"&gt;4.32&lt;/span&gt; per share commencing on &lt;span id="xdx_907_eus-gaap--ClassOfWarrantOrRighstDateFromWhichWarrantsOrRightsExercisable_dd_c20210325__20210326_z40gebeuJlf1" title="Warrant exercisable date"&gt;May 24, 2021&lt;/span&gt;

warrants are free standing financial instruments that are legally detachable and separately exercisable from the common stock included
in the registered direct offering. Management also determined that on the Issuance Date, the Company did not have sufficient authorized
and unissued shares to settle the warrants, and as such required classification as a liability pursuant to ASC 815 &lt;i&gt;&#x201c;Derivative
Instruments and Hedging&#x201d;&lt;/i&gt;. In accordance with the accounting guidance, the outstanding warrants were recognized as a warrant
liability on the balance sheet and were measured at their inception date fair value and subsequently re-measured at each reporting period
with changes being recorded as a component of other income in the statement of operations.&lt;/span&gt;&lt;/p&gt;

&lt;/span&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;Pursuant to ASC 815-40-35-8, the Company reclassified the warrant liability

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company has presented the fair value measurement as a Level 3 measurement, relying on unobservable inputs reflecting management&#x2019;s
assumptions. Level 3 measurements, which are not based on quoted prices in active markets, introduce a higher degree of subjectivity
and may be more sensitive to fluctuations in stock prices, volatility rates and U.S. Treasury Bond rates and could have a material impact
on future fair value measurements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company uses the Black Scholes model, based on the adjusted historical volatility rates for fair value measurements through the date
of stockholder approval (i.e., May 24, 2021). Management has determined the Black Scholes model to be the most reliable and least volatile determinate of
the current fair value of the warrants. It is the Company&#x2019;s expectation to maximize on all observable market inputs for the warrants
and calibrate the model to incorporate relevant observable market data into the fair value measurement at each future measurement date,
if applicable.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;During
the six months ended June 30, 2021, the Company recognized a gain of $&lt;span id="xdx_90C_eus-gaap--DerivativeGainOnDerivative_c20210101__20210630_pp0p0"&gt;1,092,441
&lt;/span&gt;&lt;/span&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;on the change in fair value of the warrants.&lt;/span&gt;&lt;/p&gt;

June 23, 2020, the board of directors (the &#x201c;Board&#x201d;) of the Company adopted the Sigma Labs, Inc. 2020 Stock Appreciation Rights
Plan (the &#x201c;Plan&#x201d;). The purposes of the Plan are to: (i) enable the Company to attract and retain the types of employees,
consultants and directors (collectively, &#x201c;Service Providers&#x201d;) who will contribute to the Company&#x2019;s long range success;
(ii) provide incentives that align the interests of Service Providers with those of the shareholders of the Company; and (iii) promote
the success of the Company&#x2019;s business. The Plan provides for incentive awards that are only made in the form of stock appreciation
rights payable in cash (&#x201c;SARs&#x201d;). No shares of common stock were reserved in connection with the adoption of the Plan since
no shares will be issued pursuant to the Plan.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;SARs
may be granted to any Service Provider. A SAR is the right to receive an amount equal to the Spread with respect to a share of the Company&#x2019;s
common stock (&#x201c;Share&#x201d;) upon the exercise of the SAR. The &#x201c;Spread&#x201d; is the difference between the exercise price
per share specified in a SAR agreement on the date of grant and the fair market value per share on the date of exercise of the SAR. The
exercise price per share will not be less than 100% of the fair market value of a Share on the date of grant of the SAR. The administrator
of the Plan will have the authority to, among other things, prescribe the terms and conditions of each SAR, including, without limitation,
the exercise price and medium of payment and vesting provisions, and to specify the provisions of the SAR Agreement relating to such
grant.&lt;/span&gt;&lt;/p&gt;

Company granted, pursuant to the Plan, (i) 60,094 SARs to its President and Chief Executive Officer, (ii) 12,019 SARs to its Vice
President of Business Development, (iii) 24,038 SARs to its Chief Technology Officer, and (iv) 18,028 SARs to its Chief Financial
Officer. The exercise price of each such SAR is $2.63, which was the closing price of the Company&#x2019;s common stock on the date
of grant. Such SARs expire on the fifth anniversary of the grant date and may be settled only in cash. Additionally, each such SAR
will vest and become exercisable in three equal (as closely as possible) installments on each of the first, second and third
anniversaries of the grant date, subject, in each case, to the applicable SAR holder being in the continuous employ of the Company
on the applicable vesting date, and, in the event of a Change in Control (as defined in the Plan), will become immediately vested

addition, a holder may at any time, alternatively, convert all, or any part, of its Series D Preferred Shares at an alternative
conversion price, which equals the lower of the applicable conversion price then in effect, and the greater of (x) $1.80 and (y) 85%
of the average volume weighted average price (&#x201c;VWAP&#x201d;) of the Common Stock for a five (5) trading day period prior to
such conversion. Upon the occurrence of certain triggering events, described in the Certificate of Designations, including, but not
limited to payment defaults, breaches of transaction documents, failure to maintain listing on the Nasdaq Capital Market, and other
defaults set forth therein, the Series D Preferred Shares would become subject to redemption, at the option of a holder, at a 125%

Company granted, pursuant to the Plan, (i) 60,094 SARs to its President and Chief Executive Officer, (ii) 12,019 SARs to its Vice
President of Business Development, (iii) 24,038 SARs to its Chief Technology Officer, and (iv) 18,028 SARs to its Chief Financial
Officer. The exercise price of each such SAR is $2.63, which was the closing price of the Company&#x2019;s common stock on the date
of grant. Such SARs expire on the fifth anniversary of the grant date and may be settled only in cash. Additionally, each such SAR
will vest and become exercisable in three equal (as closely as possible) installments on each of the first, second and third
anniversaries of the grant date, subject, in each case, to the applicable SAR holder being in the continuous employ of the Company
on the applicable vesting date, and, in the event of a Change in Control (as defined in the Plan), will become immediately vested
and exercisable as long as the applicable holder is in the Company&#x2019;s employ immediately prior to the Change in Control, and
will otherwise be on such other terms set forth in the form of Stock Appreciation Rights Agreement.</SGLB:StockAppreciationRightsGrantedDescription>

Estimates</span></b> - The preparation of financial statements in conformity with generally accepted accounting principles in the United States

of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimated by management. Significant accounting estimates that may materially
change in the near future are impairment of long-lived assets, values of stock compensation awards and stock equivalents granted as offering
costs, and allowance for bad debts and inventory obsolescence.</span></p>

Company has presented the fair value measurement as a Level 3 measurement, relying on unobservable inputs reflecting management&#8217;s
assumptions. Level 3 measurements, which are not based on quoted prices in active markets, introduce a higher degree of subjectivity
and may be more sensitive to fluctuations in stock prices, volatility rates and U.S. Treasury Bond rates and could have a material impact
on future fair value measurements.</span></p>

Company uses the Black Scholes model, based on the adjusted historical volatility rates for fair value measurements through the date
of stockholder approval (i.e., May 24, 2021). Management has determined the Black Scholes model to be the most reliable and least volatile determinate of
the current fair value of the warrants. It is the Company&#8217;s expectation to maximize on all observable market inputs for the warrants
and calibrate the model to incorporate relevant observable market data into the fair value measurement at each future measurement date,
if applicable.</span></p>

Plan (the &#8220;Plan&#8221;). The purposes of the Plan are to: (i) enable the Company to attract and retain the types of employees,
consultants and directors (collectively, &#8220;Service Providers&#8221;) who will contribute to the Company&#8217;s long range success;
(ii) provide incentives that align the interests of Service Providers with those of the shareholders of the Company; and (iii) promote
the success of the Company&#8217;s business. The Plan provides for incentive awards that are only made in the form of stock appreciation
rights payable in cash (&#8220;SARs&#8221;). No shares of common stock were reserved in connection with the adoption of the Plan since
no shares will be issued pursuant to the Plan.</span></p>

may be granted to any Service Provider. A SAR is the right to receive an amount equal to the Spread with respect to a share of the Company&#8217;s

per share specified in a SAR agreement on the date of grant and the fair market value per share on the date of exercise of the SAR. The
exercise price per share will not be less than 100% of the fair market value of a Share on the date of grant of the SAR. The administrator
of the Plan will have the authority to, among other things, prescribe the terms and conditions of each SAR, including, without limitation,
the exercise price and medium of payment and vesting provisions, and to specify the provisions of the SAR Agreement relating to such
grant.</span></p>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

Company granted, pursuant to the Plan, (i) 60,094 SARs to its President and Chief Executive Officer, (ii) 12,019 SARs to its Vice
President of Business Development, (iii) 24,038 SARs to its Chief Technology Officer, and (iv) 18,028 SARs to its Chief Financial
Officer. The exercise price of each such SAR is $2.63, which was the closing price of the Company&#8217;s common stock on the date
of grant. Such SARs expire on the fifth anniversary of the grant date and may be settled only in cash. Additionally, each such SAR
will vest and become exercisable in three equal (as closely as possible) installments on each of the first, second and third
anniversaries of the grant date, subject, in each case, to the applicable SAR holder being in the continuous employ of the Company
on the applicable vesting date, and, in the event of a Change in Control (as defined in the Plan), will become immediately vested
and exercisable as long as the applicable holder is in the Company&#8217;s employ immediately prior to the Change in Control, and
will otherwise be on such other terms set forth in the form of Stock Appreciation Rights Agreement.<span></span>
