Summary

 PART I

Sigma  is  a  software  company  that  has  developed  In-Process-Quality-Assurance  (“IPQA”)  software  known  as  PrintRite3D®.  This  technology  is  also  sometimes
referred  to  as  Real-Time-Computer-Aided  Inspection  (“CAI”).  Sigma  believes  that  its  PrintRite3D®  solves  the  major  problem  that  has  prevented  large-scale  metal  part
production using 3D printers for cost efficient production runs.

3D metal manufacturing, also known as Additive Manufacturing, is a technology that uses lasers to sculpt parts by welding powdered metals into 3-dimensional (3D)
objects and, to date, the quality of these parts can vary from part to part in a single production run, as well as from machine to machine in a production line. Traditional quality
assurance methods relying on statistically based post-process inspection methods so well proven by “Subtractive Manufacturing” cannot be used effectively to improve and
assure  quality  of  parts  manufactured  using  3D  metal  printers.  The  aforementioned  traditional  quality  assurance  methods  are  based  on  a  manufacturing  process  that  is  the
opposite of 3D Additive Manufacturing; Subtractive Manufacturing begins with quality-assured already formed pieces of metal as a raw material (not powdered metal as is used
as raw material in 3D) and machines it with equipment such as lathes, milling machines, and CNC machines to subtract metal and thus form finished metal parts, or by casting
molten metal into molded parts usually to then be further machined. Since the metal used in Subtractive Manufacturing is already of proven quality, the quality of the metal for
all parts in a production run is known to be the uniform, subject to post process inspection of a statistically significant sample.

The lynchpin reality of 3D Additive Manufacturing quality assurance is illustrated by the fact that if a 3D metal manufacturing machine fabricates 10 parts, and quality
inspectors then rigorously inspect three of them, the inspectors will have learned about the quality of only the three parts they destroyed or CT scanned and nothing that is
sufficient to confirm or reject the quality of the remaining seven. Quality assurance of 3D Additive metal parts requires manufacturers to institute procedures to inspect 100% of
the parts being made. Sigma believes that the best, indeed, the only known way to attain high yields for both manufacturing quality and cost efficiency is an In-Process-Quality-
Assurance  (IPQA®)  approach  that  examines  each  part  in  real  time  as  it  is  being  manufactured,  determines  in  real  time  whether  it  meets  quality  specifications  and  permits
machine operators to act on the information if a part is beginning to deviate from its design specifications.

GE Aviation stated in 2016 that it planned to commit $3.5 billion by 2020 to, among other things, build a metal 3D production facility to produce 3D printed metal
parts for its Leap engine and other engines. Starting in September 2016 and continuing into 2017 GE has spent over $1 billion buying controlling interests in AM equipment
manufacturers, Concept Laser and Arcam AB, has announced that it invested over $300 million creating AM manufacturing capability in both the United States and India, and
was an investor in a $115 million series D investment round of Desktop Metal, a metal 3D printing company. Sigma Labs has learned from its interactions in the marketplace
that the pent-up demand apparent from GE and others, such as Airbus, to press forward into advanced 3D manufacturing production are taking place with the assumption that
in-process quality assurance capacity will likely emerge either from their own internal efforts or be attained through licensing, or possibly acquisition. In the meantime, CT
scans and other costly post-process inspection appear to be an accepted cost as initially sustainable in the startup phase of production. However, until companies that utilize 3D
production facilities like GE Aviation are able to effectively verify that each part conforms to design specifications of attributes of shape, density, strength and consistency in
real-time  during  the  manufacturing  process,  we  believe  that  such  companies  will  be  at  risk  of  letting  some  substandard  parts  through  and,  also,  be  unable  to  improve  the
workflow to high quality cost-optimum yields of 3D printed metal parts. We believe that our principal product, PrintRite3D®, which can be positioned “inside” a 3D metal
printer, solves these problems by determining if each part is being made to the quality specifications of the Design/Specification file as each part is being made. Our software
enables 3D prototyping to evolve forward into 3D manufacturing by providing a software with an algorithms-based tool that addresses and overcomes the quality issues that are
specific to 3D Metal Additive Manufacturing and that are not solved using the quality methods derived for Subtractive manufacturing. No matter how much acuity and at what
cost of a suite of post process inspection tools might provide 3D manufactured metal parts, it currently can only assure quality by rejecting fully formed parts. PrintRite3D® is
able to replace these ‘interim’ post process solutions such as CT scanning with a tool that has substantially lower operating costs and can attain higher yields by inspecting parts
as they are being made and providing machines and their operators actionable information that includes the option of stopping manufacture of given part(s) while operations
continue  to  complete  parts  that  are  in  specification,  thus  saving  time  and  money  while  raising  yields.  PrintRite3D®  also  gives  operators  information  from  run  to  run  that
enables them to ‘learn up’ quality for a given machine by using PrintRite3D® data about machine behaviors that can then be offset by making adjustments to power settings
directed at a given sector.

We have filed 18 patent applications on our In-Process Quality Assurance™ (“IPQA®”) process and procedure for advanced manufacturing. In addition, we anticipate
that our core PrintRite3D® software will enable our customers to combine their digital manufacturing technologies with our 3D manufacturing QA to achieve both cost savings
and more reliable parts. We believe that certain vertical markets would benefit from our technology and software, including aerospace, defense, bio-medical, power generation,
and oil & gas industries because: (1) they each stand to benefit by taking advantage of the weight/strength/performance ratios that can often be optimized by taking advantage of
3D design; (2) they each stand to benefit by taking maximum advantage of 3D manufacturing’s material cost savings resulting from designing parts to needed tolerances while
requiring less metal; and (3) there are severe consequences for quality failures in some of their products. We provide our software products to customers in the form of Software
as a Service (“SaaS”).

About 3D Printing

3D printing (“3DP”) or additive manufacturing (“AM”) is changing the world by producing real metal parts from a computerized input. 3D printing has been applied
to the manufacture of plastic parts for decades. 3D manufacturing of metal parts involves directing a laser or other energy source at a layer of powdered metal and melting it.
These layers become melted together from the bottom up. Worldwide revenues attributable to 3D manufacturing for metal products were $88.1 million in 2015 (Wohlers Report
2016, 3D Printing and Additive Manufacturing State of the Industry – Annual Worldwide Progress Report). By 2016, annual sales of the powdered metals used for raw material
in metal Additive Manufacturing had grown to $126 million. Large powdered metal suppliers surveyed by Wohlers about their growth forecasts for 2017 averaged expectations
of a 59% increase for 2017. . According to Sigma’s experience in costing and pricing the manufacturing of AM metal parts, as confirmed by consultation with other service
providers, the total powdered metal sales forecast for 2017 is enough raw material to produce a “retail value” of the metal parts of ~$800 million.

The application of 3D printing to high-tolerance, precision manufactured metal parts has only recently emerged. 3D printing of metal parts today represents only a
minor percentage of all 3D manufacturing. However, we believe the greatest future growth for 3D printing appears to be in metal parts, given the interest and investment being
made by Fortune 100 companies, Federal government laboratories and agencies as well as university-based institutions. These high-end manufacturers and technology leaders
are strongly focused on helping transform analog manufacturing of precision, high-tolerance parts in the U.S. to a digital manufacturing encompassing automation, robotics and
closed-loop  process  control.  We  believe  that  the  on-going  success  of  3D  printing  for  metal  parts  will  be  highly  dependent  upon  the  evolution  of  digital  quality  assurance
procedures used, such as our PrintRite3D® process control.

About Quality Assurance in 3D Printing

Current methods for providing quality in 3DP are generally either (i) inaccurate due to use of procedures that do not recognize and measure the primary quality issues
of 3D metal manufacturing or due to the misuse of statistically based assessments, or (ii) are cost prohibitive due to the expense of equipment required to examine the interior of
complex dense parts that 3D manufacturing can create. After 3D-manufacture, costs are normally incurred by using non-destructive technologies such as ultrasound and non-
traditional CT technology on these parts, and old-fashioned visual inspection. Destructive testing of 3D parts is a mis-applied carryover from current Subtractive Manufacturing
quality assurance practice, in which the great part to part consistency of traditional metal machining equipment permits quality inspectors to infer the quality of a production run
by cutting up and analyzing a statistically relevant number of parts. The test result of the parts that are destroyed and analyzed have been, at great time and expense, statistically
demonstrated  to  be  representative  of  the  rest  of  the  parts  in  the  production  lot.  The  underlying  premise  of  quality  assurance  for  Subtractive  Manufactured  parts  is  that  if  a
machine is set up properly, then all parts it produces will be the same. This simple, effective and accurate quality system does not apply to Additive Manufacturing, in which
each part is built in an average production lot of 5-20, and in which quality variance may occur from part to part and within any part notwithstanding that the AM machine
settings are the same. Therefore, unable to rely on a traditional statistically based quality system, 3D Manufacturing’s optimum quality assurance system would evaluate the
quality of each individual part. PrintRite3D®’s in-process quality inspection approach of each part individually allows a manufacturer to use AM to form a single part, such as a
hip replacement or one spare aircraft part needed on an aircraft carrier, or several lots of the same part, in large quality – each approved or rejected in real time and based upon
complete  inspection  during  fabrication.  We  offer  our  customers  the  ability  to  use  real-time  sensors  to  track  individual  scans  of  each  layer,  and  our  software  continuously
analyzes the part health so that when it is finished we can determine if it meets the production quality standard set by the customer. We believe our PrintRite3D® software could
reduce inspection costs by a factor of 10 and development time for new parts by 50% or more because IPQA permits factories to make the part manufactured the constant and
the machines manufacturing them the variable. Consequently, the lower cost statistical based post-process inspection methods that work well with Subtractive Manufacturing
could be successfully and economically applied to parts made with 3D Metal machines, and because utilizing PrintRite3D® for design reduces the number and iterations of
development parts required to lead to a final design. Most importantly is the ability of our software to reduce risk associated with the qualification and certification of printed
parts.

5

 
 
 
 
 
 
 
 
By using PrintRite3D® software, a high-precision manufacturer would have the ability to offer its customers product warranties and assurances that its printed parts
were produced in compliance with stringent quality requirements. Orders for our software have been received from Honeywell Aerospace, Aerojet Rocketdyne, Woodward,
Siemens Turbomachinery, Pratt and Whitney, and Solar Turbines.

We believe there is potential for our PrintRite3D® software to be incorporated into a majority of 3D metal printing devices made by companies like Electro-Optical

Systems (“EOS”), Additive Industries, Concept Lasers, Trumpf Lasers, Renishaw, Sentrol, Farsoon, Desktop Metal and others.

Sigma’s Cloud-Based IIoT Solutions

The process of making a 3D printed part could start with our customers loading a computer aided design (“CAD”) model of the part into the Cloud as shown in “A” in
Figure 1. Next, computer aided engineering (“CAE”) and/or computer aided manufacturing (“CAM”) instructions are sent to the 3D printer (see “B”, as shown in Figure 1).
Metal powder in the machine is then deposited onto the build platform where a laser beam, or other energy source, focused onto the build platform melts each successive layer
of powder in 20-60 micron increments. Our PrintRite3D SENSORPAK® (see “C” in Figure 1) detects, records, analyzes and compares the part as it is being made layer-by-
layer  against  the  CAD/CAM  specifications  and  physical  reference  points  for  quality  assurance  during  manufacturing.  Our  PrintRite3D  INSPECT®,  Version  3.02  software
utilizes our patent applied for TED tool to determine compliance of each part for its metallurgical quality. Our alpha version of PrintRite3D CONTOUR® software determines
the shape and conformity of a part in real-time manufacture with its geometric design specification.

Our PrintRite3D® CAI web-based software suite (see “D” in Figure 1) resides in situ and/or in the Cloud (see “A” in Figure 1) of the Industrial Internet of Things
(“IIoT”). We enable manufacturing engineers to confirm the part quality layer-by-layer, provide for manufacturing statistical process control and harvest, aggregate, and analyze
big data from the real-time manufacturing data collected from our PrintRite3D SENSORPAK® (see “C” in Figure 1), as well as post-process manufacturing data collected by
our customers (see “E” in Figure 1).

Our specialized sensor suite (see “C” in Figure 1), known as PrintRite3D SENSORPAK®, is an edge computing device, which means that it can be operated outside of a
customer’s  primary  computer  hardware  and  software  systems  while  delivering  actionable  information  to  these  systems.  Thus,  PrintRite3D  SENSORPAK®  contains  the
modular hardware and software necessary to connect to “cyber-physical” objects (see “B” in Figure 1) living on the manufacturing floor. It allows for bi-directional information
flow between the manufacturing floor and the Cloud (see “A” in Figure 1). It starts with a million-fold data reduction required to manage and analyze the very large quantities
of data garnered that layer by layer monitoring +/- 30 Micron thicknesses create. It finishes with our PrintRite3D® Digital Quality Record (“DQR”) and report, which provides
customers with product guarantees and assurances that parts were produced in compliance with stringent quality standards. It can collect, analyze, aggregate, filter, and then
further communicate data from the manufacturing floor to the Cloud (see “A” in Figure 1) and enable links to other areas (see “F” in Figure 1) of the IIoT.

We  generate  revenues  through  PrintRite3D®  hardware  and  CAI  software  licensing  of  our  PrintRite3D®  technology  to  customers  that  seek  to  improve  their
manufacturing production processes, and through ongoing annual software upgrades and maintenance fees. Additionally, we generate revenues from our contract manufacturing
activities in metal AM. By running a small-scale contract AM services operation, we are able to understand the current needs of our customers and where they are going with
their next-generation product development efforts. Contract AM further allows us a means for material on-going partial self-funding of our IPQA®-enabled R&D and product
development activities for CAI software. We provide our AM contract manufacturing services to customers in the form of Quality as a Service (“QaaS”). Starting with our
PrintRite3D® cloud-based SaaS model, customers will contract with us for CAE, CAM and CAI services to generate and establish a Digital Quality Record (DQR) for AM built
parts. Each DQR is cloud-based and allows for archiving and storage of quality data, access to our big data ANALYTICS™ software App for continuous quality monitoring and
improvement, and automatic industry benchmarking while maintaining firewalls between company-specific data.

In  late  2015,  we  launched  two  programs  −  an  Early Adopter  Program  (“EAP”)  and  an  Original  Equipment  Manufacturer  (“OEM”)  Partner  Program  −  designed  to
broaden our market presence and speed adoption of our PrintRite3D® technology. The EAP was designed to attract end user customers who have an existing, installed base of
3D metal printers and to offer them incentivized pricing in return for feedback on engineering and beta releases of our PrintRite3D® software Apps. Our OEM Partner Program
was  specifically  designed  for AM  machine  manufacturers  seeking  to  embed  our  PrintRite3D®  quality  assurance  software Apps  directly  into  their  machines  for  customers
purchasing a turnkey solution for their new AM machine purchases.

We possess the resident expertise to provide manufacturing materials and process (“M&P”) engineering services and support to companies using our PrintRite3D®
software Apps for metal AM. Accordingly, in addition to our primary business focus, we intend to generate revenues by providing such engineering services and support to
businesses that license our PrintRite3D® software Apps.

Our  President  and  Chief  Technology  Officer  has  worked  at  or  with  the  Edison  Welding  Institute  and  United  States  Department  of  Energy  (“DOE”)  national
laboratories (including the Knolls Atomic Power Laboratory, Bettis Atomic Power Laboratory, Los Alamos National Laboratory and Sandia National Laboratory) over the past
34  years.  Due  to  his  work  with  the  DOE,  our  President  and  Chief  Technology  Officer  has  developed  extensive  relationships  with  the  DOE  and  its  network  of  national
laboratories.  Accordingly,  we  expect  to  leverage  these  relationships  in  connection  with  licensing  and  developing  technologies  created  at  such  national  laboratories  for
commercialization in the private sector.

Early-Stage Technology Commercialization and Market Positioning

Since  our  inception  in  2010,  we  have  made  progress  in  bringing  early-stage  disruptive  technology  from  scientific  concept  and  curiosity  to  practical  reality,  as

described below.

PrintRite3D® Quality Assurance Software for Computer-Aided Inspection of Metal Additive Manufacturing

We believe that AM will significantly impact the manufacturing landscape. AM results in very efficient metal utilization for parts made on-demand, and utilizes a wide
variety of rapid prototyping methods. As a result of AM, parts can go straight from computer-aided designs (CAD) and 3D computer models to actual, physical parts through
the use of computer-aided engineering (CAE) and computer-aided manufacturing (CAM) steps. However, there are severe challenges in connection with 3D printing of metal
parts. Current manufacturing processes are not capable of making every part right the first time. Also, process consistency and repeatability require further development for
metal  parts  and  this  is  a  typical  case  for  emerging  technologies.  Although  many  industry  experts  have  lamented  that  3D  Printing  for  metal  parts  is  limited  in  current
applications, we are developing our IPQA®-enabled technology into a hardware and software suite of products for CAI of AM known as PrintRite3D®, which we expect will
address  some  these  shortcomings  and  enable  mass  production  for  metals AM  technology  to  be  realized  sooner  than  would  otherwise  be  possible  given  its  current  state  of
maturity. PrintRite3D® comprises a suite of CAI software apps that address the three fundamental problems facing metal AM today, namely: assuring the metal integrity or
quality of the product; assuring the as-built geometry of the product; and, increasing the productivity or speed of the AM process.

Contract Manufacturing for Metal Additive Manufacturing

According  to  the  Wohlers  2017 Annual  Report,  industry  growth  in  the  independent  service  provider  segment  including  the  secondary  market  of  dies  and  molds
produced for and by AM machines for AM manufacturing in 2016 was an estimated $4.2 billion, up from $3.6 billion in 2015. End users are still in the early stages of adding
metal  AM  systems  to  supply  production  parts  to  aerospace  and  defense  OEMs,  such  as  GE  Aviation  (“GEA”),  Honeywell  Aerospace,  Pratt  &  Whitney,  and  Siemens
Turbomachinery.  We  believe  that  most  AM  machines  produced  through  October  2017  are  still  not  well  suited  for  production  applications.  They  have  limited  feedback
measurement and control sensors to guarantee part quality real time. Some of the latest machines available, such as EOS’s M290 machine, are beginning to be sold with limited
advanced measurement system capability.

We believe that this service provider market segment represents an opportunity for us to capture significant future portions of the demand for metal production parts by
enhancing service bureaus quality through the licensing of PrintRite3D®. Accordingly, we acquired our first EOS M290 metal printing machine in 2014. Using the M280 as its
base, the M290 adds improved energy efficiencies, faster build times, and slightly larger build platform capabilities. Through our EOS M290 machine, our customers gain the
benefits of many years of M280-proven applications while accessing the latest in DMLS® technology, as well as receiving parts certifiably produced using our state-of-the-art
PrintRite3D® quality assurance software Apps. We provide our AM contract manufacturing services to customers in the form of Quality as a Service.

A detailed description of our technologies and business follows.

PrintRite3D® Quality Assurance Software for Additive Manufacturing

The Market

An area of increasing interest in the manufacturing world is AM or 3DP. AM is a method of producing functional parts directly from computer design or CAD files

without any tooling or other processing.

The sale of AM products and services in 2016 composed of all AM products and services, but not including the aerospace and medical industries which are deemed by
Wohlers as currently too difficult to document , grew 17.8% to $6.1 billion according to Wohler’s Annual 2017 report. The AM industry is expected to grow to about $15.8
billion in 2019. In 2021, the AM industry is forecasted to grow to about $26.5 billion, all according to the Wohlers 2016 Annual Report.

Metal  parts  are  a  small  and  rapidly  growing  segment  of  this  overall  market  space  as AM  or  3D  printing  moves  from  just  making  models  to  making  actual,  fully
functional  parts.  Large  end  users  such  as  Honeywell Aerospace,  GEA  and  Boeing  Defense  view AM  as  an  enabling  process  for  many  components. A  report  in  a  series  by
Deloitte University Press on additive manufacturing published in Fall 2015 titled, “3D Opportunity For Quality Assurance and Parts Qualification,” states that, “[o]ne of the
most important barriers is the qualification of AM-produced parts. So crucial is this issue, in fact, that many characterize quality assurance (QA) as the single biggest hurdle to
widespread adoption of AM technology, particularly for metal.” We believe that OEM end user companies as well as first-tier suppliers cannot achieve their long-term AM
production goals without advanced quality assurance and control technologies for metal AM parts because current quality control methods are not sufficient to reliably allow
cost-effective manufacturing of safety- and performance-critical metal parts. We believe that our PrintRite3D® CAI technology would directly address this “important barrier”
for metal parts and allow such AM applications to move forward. In response to this need, we have experienced an increase in our installed base of PrintRite3D® systems and
we are beginning to provide material & process engineering services and support for our PrintRite3D® software licenses for our installed base at GEA, Honeywell Aerospace,
Spartacus3D, Additive Industries, Aerojet Rocketdyne, 3D Material Technologies, LLC, Woodward, Siemens, Pratt & Whitney, and the Edison Welding Institute (“EWI”).

We have ongoing contracts that include a Phase 3 project with Honeywell Aerospace funded by the Defense Advanced Projects Agency (“DARPA”) on the application
of our PrintRite3D® technology to performance-critical AM metal parts for aerospace. This project is vitally important because it provided an early opportunity to demonstrate
how our IPQA®-enabled PrintRite3D® software Apps will reduce our customers’ reliance on unnecessary post process inspection, ultimately reducing costs and improving
quality for AM of highly critical aerospace metal components. Also, we were a participant on a GEA led team of companies and universities, which was awarded a research
contract by the National Additive Manufacturing Innovation Institute (“NAMII” or America Makes) titled, “In-Process Quality Assurance™ for Laser Powder Bed Production
of  Aerospace  Components”.  The  contract  has  the  stated  objective  of  maturing  our  In-Process-Quality-Assurance™  (IPQA®)  technology  for  aerospace  applications  by
leveraging  a  development  approach  incorporating  multiple AM  OEM  machines,  multiple  superalloys,  and  multiple  product  intent  aerospace  components.  In  support  of  this
effort, we were awarded related contracts from the subcontractor Aerojet Rocketdyne to install one of our PrintRite3D® systems and software Apps on a Concept Laser M2
metal AM machine at Aerojet Rocketdyne’s Canoga Park, California facility, as well as a contract from Honeywell Aerospace to make initial test specimens for reliability and
repeatability  testing  using  our  EOS  M290  printer.  We  were  also  part  of  a  large  research  team,  led  by  the  Edison  Welding  Institute  that  was  awarded  a  grant  funded  by  the
National Institute of Standards (“NIST”) to ensure that quality parts are produced and certified for use in products made by a variety of industries and their supply chains. The
emphasis was on providing tools needed for additive manufacturing applications to progress from prototype to serial production. This program was successfully completed in
Fall 2015. We are currently a subcontractor to Honeywell Aerospace who was awarded a program in 2015 by America Makes which is designed to address Design for Additive
Manufacturing (“DFAM”) issues. In support of this program, we will use our EOS M290 printer to build canonical shapes and mechanical test specimens for evaluation by
Honeywell Aerospace.

Technology and Competitive Advantage

The evolution of AM from prototyping to volume manufacturing in production runs is occurring in, and led by, aerospace while also appearing in niche products such
as  medical  appliances  and  replacement  parts  of  diverse  applications,  including  unavailable  parts  required  by  still  deployed  but  aging  technologies. A  major  problem  for  3D
metal products production-run manufacturing today is that traditional quality systems that rely heavily on other industries’ experiences with high precision CNC machines in
Subtractive Manufacturing that lathe, mill, or drill with high precision consistency and can successfully rely on after-manufacture statistically based part sample destruction and
inspection procedures simply do not export and apply to Additive manufacturing machines. Further, post-production non-destructive test instruments from ultrasound to CT
Scans are either not effective or not cost efficient on many complex part configurations that take advantage of 3D capability, and in the case of CT scans, are prohibitively
expensive  for  production  cost  efficiency.  The  most  important  feature  of  our  PrintRite3D®  is  that  it  develops  actionable  quality  and  process  control  data  of  manufacturing
information  in  real-time  and,  when  no  flaws  are  detected,  can  provide  manufacturers  and  their  end-users  with  a  part-by-part  quality  certification  backed  up  by  a  file  of
supporting data.

Our PrintRite3D® suite, as described below, is composed of hardware, software, data analytics, and proprietary algorithms. The hardware is an array of photodiodes,

non-contact pyrometer, and a data processing unit that can be either sold with an AM manufacturing machine unit by an OEM manufacturer or retrofitted on customers’ sites.

●

●

PrintRite3D® SENSORPAK™ – the auxiliary sensor and hardware kit that sits on every AM machine to collect the data to drive the software.

PrintRite3D® INSPECT™ – software which verifies quality layer by layer.

The following software modules are currently in development:

●

●

●

●

PrintRite3D® CONTOUR™ – software which assures the as-built geometry.

PrintRite3D® ANALYTICS™ – software that harvests, aggregates, and analyzes big data from in-process manufacturing data and post-process manufacturing data.

PrintRite3D® THERMAL™ – software which predicts the residual stress and distortion in the part.

PrintRite3D® CLOSED LOOP CONTROL- software that signals for laser adjustments required to correct a developing deviance from design specification detected
by other PrintRite3D® modules.

The  proprietary  software  and  its  embedded  algorithms  process  the  substantial  amount  of  layer  by  layer  data  gathered  and  then  informs  operators  of  the  Quality
Compliance status of each part in a build. We have been active in patent protecting our in-depth data analysis and quality algorithms to link our analysis to root cause metallurgy
for determining the granular quantification of the part conformance to metallurgical requirements such as tensile strength. Concurrent with assessing the internal quality features
of  all  parts  in  a  build,  PrintRite3D®  deploys  its  CONTOUR™  module  that  measures  each  part’s  adherence  to  the  configuration  specification  of  both  internal  channels  and
external form. OEM machine manufacturers as well as control system manufacturers may use the Sigma data stream to direct machine performance adjustments.

We  have  developed  a  tool  that  enables  companies  using Additive  Manufacturing  equipment  for  metal  parts  to  move  from  prototyping  on  into  production  runs  by
assuring quality in a uniquely reliable and cost-effective fashion. Not only does PrintRite3D® enable a single AM machine to operate at high quality yields, by measuring the
product of the manufacturing equipment rather than just the equipment settings, it also is a reliable method to assure and document uniform quality assurance of a single part’s
specification being manufactured by factories utilizing a number of different AM machines.

We believe that the broad domain coverage of our PrintRite3D® patents and metallurgical know-how make the licensing of our product suite to be the best means by
which Additive Manufacturing OEM equipment manufacturers can offer in-process-quality-monitoring that certifies and documents the quality of all parts that pass continuous
inspection.  PrintRite3D®  provides  3D  metal  manufacturing  equipment  makers  with  a  patent  protected  data  configuration  of  information  that  the  manufacturers  may  use  to
adjust  controls  of  their  equipment  in  response  to  real-time  quality  information  by,  for  example,  precisely  adjusting  laser  power  to  sustain  manufacturing  to  design  and
specification.

Our IPQA®-enabled PrintRite3D® software Apps appear well suited to meet the needs of metal AM at this critical juncture in its development. Our technology will
allow  metal AM  to  be  used  during  manufacturing  of  safety-critical  or  performance-critical  metal  parts,  such  as  used  in  aerospace,  defense  and  biomedical.  Currently,  these
applications are difficult because the part quality cannot be completely guaranteed using today’s conventional nondestructive inspection technologies, because using inspection
after manufacturing is difficult, costly and does not find all defects of concern. Therefore, we believe that PrintRite3D® could be an enabler for metal AM to realize its full
potential.  We  have  unique  and  patent  protected  offerings  in  this  field.  Furthermore,  as  a  greater  number  of  these AM  applications  could  be  cloud-based,  the  PrintRite3D®
technology is fully compatible with highly networked, cloud- or web-based implementation – subject to the data and intellectual property restrictions which may be imposed by
some companies for competitive reasons.

Our proprietary PrintRite3D® software Apps have been demonstrated and tested at many manufacturing sites around the world. We believe these demonstrations have
served to validate the underlying technology of PrintRite3D® INSPECT™ and SENSORPAK™ software and hardware modules, respectively. In addition, we have developed
relationships with experienced aerospace companies in North America that have assisted in the  validation  of  the  underlying  technology  for  our  PrintRite3D®  software App
known as CONTOUR™.

We are continuing to work with Honeywell Aerospace on the separate development of our PrintRite3D® CONTOUR™ software App for metal-based AM under our
Trial Evaluation Agreement with Honeywell Aerospace, which sets forth the parties’ intent to use Honeywell’s Advanced Manufacturing Engineering Center as a beta test site
for our PrintRite3D® CONTOUR™ software module. In further support of this effort, in 2015 Honeywell Aerospace installed its second PrintRite3D® system on one of its
Concept Laser M2 machines at their Advanced Manufacturing Engineering Center in Phoenix, Arizona.

We  have  expanded  our  market  presence  and  associated  installed  base  of  PrintRite3D®  systems  through  our  Early  Adopter  Program  (“EAP”)  and  our  Original
Equipment Manufacturer (“OEM”) Partner Program to include European companies in France, Germany and The Netherlands. These European partners’ installations are key to
our long-term strategy to broaden its installed base through our EAP as well as gain market presence though embedded OEM offerings of our PrintRite3D® technology. Our
PrintRite3D® product commercialization efforts reflect the strategic nature of our selective alliance partnerships.

We believe PrintRite3D® is uniquely positioned to grow into this market as its technology is platform independent and deployable with all currently known metal AM

manufacturing units.

Business Model

Our commercialization strategy for PrintRite3D® products is:

●

●

●

●

Enter into early adopter license agreements with high potential future AM equipment manufacturers and complex part AM manufacturing service bureaus;

Enter into OEM license agreements for PrintRite3D® to be integrated directly into the printers of major AM equipment manufacturers;

Effective September 1, 2017, target and install units only at companies that are already manufacturing 3D metal parts and need to solve a quality yield problem; and

Provide manufacturing engineering consulting services to third parties that have needs in developing quality assurance tactical methods for manufacturing.

PrintRite3D® is designed to run on different machine platforms which allow us to maximize our product offering to the entire AM metal market. The target markets

include OEMs both on the AM software side as well as OEM machine producers and end users.

We  believe  another  much-needed  area  for AM  metal  parts  manufacturing  is  in  software Apps  for  reducing  design  and  development  cycle  times,  saving  the  end
customer time and money. In support of that, in 2016, we entered into a Technology Development Agreement with 3DSIM, LLC of Park City, Utah, to pursue commercial metal
AM software opportunities for rapid qualification and part certification. These software Apps could form the underpinnings and backbone of a conceptual software App known
as THERMAL™. We expect in the future to attempt to develop and offer a PrintRite3D® suite of Apps which would be specifically developed to improve part designs and
reduce traditional trial and error design approaches for features such as distortion control.

To summarize, we have formed an operating division focused on real-time, advanced quality assurance solutions for additive manufacturing thereby increasing the
value of the AM part. Although in the past our revenues have been generated mainly through engineering consulting services we provided to third parties, we have generated
revenues from December 2013 through January 2018 through sales and licensing of our PrintRite3D® systems and software.

Technology and Competitive Advantage Demonstrated On-site

We currently have an AM 3D metal printing facility that employs state-of-the-art technology from the leading provider of metal AM systems, Electro-Optical Systems.
While our current printing capacity is limited, we believe that a unique selling point or competitive advantage both for system sales of PrintRite3D® as well as local service
bureau part sales is our demonstrable on-site PrintRite3D® technology. Our EOS M290 printer  is  outfitted  with  our  latest  PrintRite3D®-enabled  technology  allowing  us  to
provide  customers  with  the  necessary  documented  objective  evidence  that  a  part  is  being  built  (and  has  been  completed)  in  precise  accord  with  the  design  specification,  or
Quality-as-a-  Service  (QaaS)  data  package,  to  ensure  they  can  meet  compliance  with  their  design  intent  and  ultimately  end-user  performance  requirements  for  their  highly-
critical and demanding components. Our QaaS starts with our PrintRite3D® cloud-based SaaS model. Customers will contract with us to generate and establish a digital quality
record for AM built parts based on Design for Additive Manufacturing (“DFAM”) principles. Each DQR is cloud-based and allows for archiving and storage of quality data.
The Reports both  provide  data  to  and  have  retrieval  access  from  our  big  data ANALYTICS™  software App.  The  cloud  based  system  provides  capability  and  resources  for
continuous  quality  monitoring  and  improvement.  Concurrently,  it  will  automatically  compare  build-data  to  industry  benchmarking.  Sigma  has  built  in  firewalls  to  shield
company-specific  data.  Our  QaaS  service  benefits  our  customers  by  providing  independent  quality  assurance  and  increased  process  intelligence  and  access  to  our  latest
proprietary big data ANALYTICS™ software Apps for trending and additional manufacturing intelligence.

Business Purpose

Our AM 3D metal printing facility serves three business purposes. First, it is a demonstration facility that allows us a means of demonstrating our IPQA products for a
prospective customer without them having to first install it on their equipment. Second, the printing facility allows us to stay current with the market’s needs by manufacturing
high  technology  prototypes  and  then  evaluating  the  challenges  that  each  new  configuration  poses.  Third,  the  in-house  printing  facility  enables  us  to  conduct  research  that
deepens our own IPQA products.

Recent Developments (in reverse chronological order)

On April 6, 2018, the Company closed a private placement of equity securities resulting in net proceeds of approximately $840,000, after deducting commissions and

other offering expenses payable by the Company.

On March 28, 2018, Morf3D repaid Sigma in full for the $500,000 loan with interest that Sigma had extended to Morf3D on March 27, 2017.

On March 26, 2018, we announced that we entered into a Cooperative Research and Development Agreement (CRADA) with the National Institute of Standards and
Technology  (NIST).  NIST  and  Sigma  will  study  the  effects  of  recycled  powder  and  part  placement  on  process  variability  and  part  quality  using  Sigma’s  PrintRite3D®
technology. The study will be the first of its kind to characterize the use of recycled powder in the Laser Powder Bed Fusion (LPBF) process using both in-situ monitoring
technology and post process mechanical property characterization, and is vitally important to the global Additive Manufacturing (AM) community because today it is known
that  changes  in  powder  characteristics  and  chemistry  may  impact  the  build  process  and  resulting  part  quality.  This  collaboration  represents  an  important  step  forward  in
providing  a  much-awaited  technical  solution  and  understanding  of  powder  reuse  and  its  implicit  cost  savings.  The  results  from  this  study  will  be  disseminated  to  the AM
community through journal articles while the in-situ and ex-situ data will be made available via the NIST AM Material Database. During this study, Sigma’s In-Process Quality
Assurance™ PrintRite3D INSPECT® software will play a key role in quantifying process variability and part quality using its proprietary Thermal Energy Density™ (TED™)
In Process Quality Metric™, an industry first for quantitatively measuring melt pool variation and part quality.

On  March  1,  2018,  we  announced  we  were  releasing  Version  3.0.2  of  our  PrintRite3D  INSPECT®  In-Process  Quality  Assurance™  (IPQA®)  software.  This
evolutionary version of PrintRite3D® is now available for new installations and upgrades to existing customers. This latest release features Sigma Labs’ new and proprietary
Thermal Energy Density™ (TED™) In Process Quality Metric™ (IPQM®), setting what the Company views as a new industry standard for quantitatively measuring melt pool
and part quality. Armed with Sigma Labs’ new PrintRite3D INSPECT® Version 3.0.2 software, process engineers will now be able to produce an alloy-specific process map
generated using Sigma Labs’ in-process TED™ metric, an industry first. This industry first approach to in-process monitoring is designed to enable rapid process qualification,
which Sigma Labs believes will result in increased production yields and faster product to market times.

On December 22, 2017, we announced that we had received a contract from Laser Zentrum Nord (LZN) GmbH, a leading Additive Manufacturing (AM) technology
and research innovator located in Hamburg, Germany for PrintRite 3D INSPECT®.  Terms  of  the  contract  have  not  been  disclosed.  The  two  companies  have  also  agreed  to
actively collaborate to certify Sigma’s IPQA® methodology and solutions for serial production 3D printing in the aerospace industry. The PrintRite3D® system will be installed
onto a SLM Solutions selective laser melting machine located at Laser Zentrum Nord GmbH in Hamburg, Germany.

installed its PrintRite3D® software on a 3D Systems’ ProX300 machine, with the potential for multiple system orders as the company ramps up to full serial production.

13

 
 
 
 
 
 
 
 
 
On April 5, 2017, we announced the release of our OEM Developer’s Kit for PrintRite3D® INSPECT™ quality assurance software version 2.0. The Company has
placed its alpha version of the OEM Developer’s Kit with a European OEM partner for immediate evaluation and incorporation into its 3D printers. The Developer’s Kit allows
an  OEM  to  seamlessly  and  quickly  embed  PrintRite3D®  technology  directly  into  their  products,  speeding  their  product  launch,  rapidly  reaching  customers  and  achieving  a
competitive advantage.

On March 29, 2017, we announced that we had entered into a long term non-exclusive commercial agreement with Additive Industries B.V. of The Netherlands. In the
course of 2017, Additive Industries advised Sigma that it rolled out its new equipment and was forced to delay initial steps with respect to this agreement, and informed Sigma
that it now intends to commence work with Sigma in 2018.

Also on March 29, 2017, and in an effort to bring enhanced solutions for additive manufacturing (“AM”) to the aerospace and defense (“A&D”) sector and capitalize
on growth in demand for 3D printed metal components within the A&D industry, we entered into a strategic alliance with Morf3D, a California-based company that specializes
in  additive  engineering  and  manufacturing  with  metals  and  that  provides  advisory  services  in  additive  manufacturing  strategy  and  technology  adoption  road-mapping.  By
leveraging  our  PrintRite3D®  quality  assurance  software,  we  believe  that  Morf3D  will  be  able  to  provide  a  means  for  its  customers  to  increase AM  production  rates  while
ensuring consistent part quality, thereby better meeting the high-quality demands of its aerospace customers. We also plan to work together with Morf3D to manufacture certain
3D printed parts.

On March 27, 2017, we completed funding of a loan in the principal amount of $500,000 to Morf3D pursuant to a Secured Convertible Promissory Note dated March
27, 2017 delivered by Morf3D to us. The loan bears interest at the rate of 7% per annum, is due and payable in full on March 27, 2018, is secured by certain assets of Morf3D,
and is convertible at our option into 10% of the outstanding shares of the common stock of Morf3D unless Morf3D exercises its right under specified circumstances to repay all
principal and accrued interest on the loan. The purpose of the loan is to provide working capital to Morf3D to, among other things, lease an EOS M 400 system for Morf3D to
expand production for contracts related to AM of high-precision aerospace & defense components, in furtherance of our strategic alliance. Morf3D repaid the loan on March 28,
2018.

On February 21, 2017, we closed an underwritten public offering of 1,410,000 units, with each unit consisting of one share of our common stock and one warrant to
purchase one share of common stock. The underwriter exercised the over-allotment option covering additional warrants to purchase up to 211,500 additional shares of common
stock. Gross proceeds to us from the offering, including the exercise of the over-allotment option, were approximately $5.8 million, before deducting underwriting discounts and
commissions and other offering expenses payable by us.

We  believe  our  technologies  will  be  beneficial  to  several  industries,  including  aerospace,  defense,  oil  and  gas,  bio-medical,  and  power  generation.  However,
developments by others may render our current and proposed technologies noncompetitive or obsolete, or we may be unable to keep pace with technological developments or
other market factors. Additionally, our competitive position may be materially affected by our ability to develop or successfully commercialize certain technologies that we
have identified for commercialization. Other general external factors may also impact the ability of our products to meet expectations or effectively compete, including pricing
pressures.

We anticipate some of our principal competitors in the United States will include AM End Users, such as GE Aviation, Honeywell Aerospace, Rolls-Royce PLC, Pratt
& Whitney; AM OEM equipment manufacturers, such as EOS, Concept Lasers, 3D Systems, Renishaw, Arcam and SLM; third party solution providers like Stratonics Inc., and
Vibrant  Corporation  that  specialize  in  designing  and  manufacturing  quality  control  monitoring  devices  used  in  industrial  applications.  Most  of  these  competitors  have
significantly greater research and development capabilities than we do, as well as substantially more sales, marketing and financial and managerial resources. These entities
represent significant competition for us. In addition, acquisitions of, or investments in, competing companies by large corporations could increase such competitors’ research,
financial, manufacturing and other resources.

Research and Development

Research  and  development  costs  are  expensed  as  incurred.  Our  research  and  development  expenses  relate  to  our  engineering  activities,  which  consist  of  the
development of our PrintRite3D® quality assurance technologies for specific customers and for the industry in general. During the years ended December 31, 2017 and 2016,
we recognized $261,310 and $87,971, of research and development costs, respectively.

Intellectual Property

We  regard  our  patents,  trademarks,  domain  names,  trade  secrets,  know-how,  and  other  intellectual  property  as  critical  to  our  success.  We  rely  on a  combination  of
patent,  trademark,  trade  secret,  other  intellectual  property  law,  confidentiality procedures,  and  contractual  provisions with  employees,  partners,  and  others  to  protect the
technology and other proprietary rights, information and know-how that comprise the core of our business. The chart below summarizes our issued patents. We are currently
prosecuting eighteen foreign and U.S. patent applications related to our IPQA® technology and rapid qualification of additive manufacturing for metal parts. Twelve of these
eighteen patent applications published between November 2015 and December 2017. There is no guarantee that the patent applications we have submitted will issue or that if
issued, they will offer adequate protection under applicable law.

Government Regulation

Any contracts that we enter into with governmental agencies will be subject to a variety of federal, state and local laws and regulations. These regulations are aimed at
preventing the inadvertent disclosure of munitions related data or the export of technical knowledge to foreign countries. The work we do with governmental units may also be
subject to laws respecting the confidentiality of any classified or national security information we receive during the course of our activities under any government contract.

Additionally, with respect to our work with government agencies, our sales are driven by pricing based on costs incurred to produce products or perform services under
contracts with the U.S. government. U.S. government contracts generally are subject to Federal Acquisition Regulations (“FAR”), agency-specific regulations that implement or
supplement  FAR,  such  as  the  DoD’s  Defense  Federal  Acquisition  Regulations  and  other  applicable  laws  and  regulations.  These  regulations  impose  a  broad  range  of
requirements, many of which are unique to government contracting, including various procurement, import and export, security, contract pricing and cost, contract termination
and adjustment, and audit requirements. A contractor’s failure to comply with these regulations and requirements could result in reductions of the value of contracts, contract
modifications or termination, and the assessment of penalties and fines and could lead to suspension or debarment from government contracting or subcontracting for a period of
time.  In  addition,  government  contractors  are  also  subject  to  routine  audits  and  investigations  by  U.S.  government  agencies  such  as  the  Defense  Contract Audit Agency
(“DCAA”). These agencies review a contractor’s performance, cost structure, and compliance with applicable laws, regulations, and standards. The DCAA also reviews the
adequacy  of,  and  a  contractor’s  compliance  with,  its  internal  control  systems  and  policies,  including  the  contractor’s  purchasing,  property,  estimating,  compensation,  and
information systems.

Employees

As  of  December  31,  2017,  we  had  12  full-time  employees.  We  are  actively  searching  for  additional,  qualified  sales  support  and  engineering  staff,  to  support  our

expanding operations in the area of IPQA® for AM.

Properties

We lease at 3900 Paseo del Sol, Santa Fe, New Mexico 87507, approximately (1) 1,306 square feet of office space at units C-15, C-16, C-17, C-20 and C-23 for a total
monthly rent expense of approximately $2,575 under the lease, which expires on July 31, 2018, (2) 172 square feet of office space at unit C-14 for a total monthly rent expense
of approximately $400 under the lease, which expires on September 30, 2018, (3) 202 square feet of office space at unit C-13 for a total monthly rent expense of approximately
$450 under the lease, which expires on October 31, 2018, (4) 708 square feet of production space at unit E-42, for a total monthly rent expense of approximately $775 under the
lease, which expires on September 30, 2018, (5) 708 square feet of production space at unit E-38, for a total monthly rent expense of approximately $800 under the lease, which
expires on July 31, 2018, and (6) 512 square feet of warehouse / production space at unit E-40, for a total monthly rent expense of approximately $650 under the lease, which
expires on September 30, 2018.

We believe that our facilities are suitable for our current needs.

 ITEM 1A. RISK FACTORS.

Investing in our securities involves a high degree of risk. Our business is subject to numerous risks. We caution you that the following important factors, among others,
could cause our actual results to differ materially from those expressed in statements made by us or on our behalf in filings with the SEC, press releases or communications with
investors and others. Any or all of our statements in this annual report and in any other public statements we make may turn out to be wrong. They can be affected by inaccurate
assumptions or by known or unknown risks and uncertainties. The factors mentioned in the discussion below will be important in determining future results. Consequently,
actual future results may vary materially from those anticipated in this annual report or our other public statements. You should carefully consider the risks described below, as
well as the other information in this annual report, including our financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition
and Results of Operations,” before deciding whether to invest in our securities. The occurrence of any of the events or developments described below could harm our financial
condition, results of operations, business and prospects. In such an event, the market price of our securities could decline, and you could lose all or part of your investment.
Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may have similar adverse effects on us.

Risks Related to Our Business

We have a limited operating history, are not currently profitable and may never become profitable.

We  have  incurred  losses  in  every  reporting  period  since  we  commenced  business  operations  in  2010  and  expect  to  continue  to  incur  significant  losses  for  the
foreseeable future. Our net loss for the years ended December 31, 2017 and 2016 were $4,577,516, and $2,196,834, respectively. As of December 31, 2017, our accumulated
deficit was $14,411,470. There is no assurance that any revenues we generate will be sufficient for us to become profitable or to maintain profitability. Our revenues for the
years  ended  December  31,  2017  and  December  31,  2016  were  $641,049  and  $966,422,  respectively,  and  our  operating  expenses  for  those  periods  were  $4,420,667  and
$3,211,258, respectively. Our current revenues are not sufficient to fund our operations. We cannot predict when, if ever, we might achieve profitability and we are not certain
that we will be able to sustain profitability, if achieved. If we fail to achieve or maintain profitability, the market price of our securities is likely to be adversely affected.

We may require additional financing to continue our operations, and there is no assurance that we will be able to obtain such financing on acceptable terms, or at all.

As  of  December  31,  2017,  we  had  cash  in  the  amount  of  $1,515,674.  We  believe  that  the  approximately  $840,000  of  net  proceeds  from  our April  6,  2018  sale  of
securities and receipt of $535,000 on a note receivable, together with our existing cash and anticipated revenues, will be sufficient to fund our operations until at least the end of
fiscal 2018. There is no assurance that any future financing that we require to fund our operations will be available on acceptable terms, or at all. Such financing, if in the form
of equity, may be highly dilutive to our existing stockholders and may otherwise include onerous terms. Such financing, if in the form of debt, may include debt covenants and
repayment  obligations  that  are  onerous  and  that  adversely  affect  our  business  operations.  If  adequate  funds  are  not  available  to  us,  we  may  be  required  to  delay,  limit  or
terminate our business operations.

Our limited operating history makes evaluation of our business difficult.

We commenced business operations in 2010 and are continuing to develop our technologies and to implement our business plan. Our ability to implement a successful
business plan remains unproven, and there is no assurance that we will ever generate sufficient revenues to sustain our business. Our relatively short operating history, together
with the other risks discussed in this “Risk Factors” section, may make it difficult for you to evaluate our business in connection with making a decision about whether to invest
in our securities.

We face the risks normally associated with a new business.

We face all of the risks inherent in a new business, including the expenses, difficulties, complications and delays frequently encountered in connection with conducting
new operations and efforts to develop and commercialize technologies. These uncertainties include developing our technologies and our brand name, raising capital to meet our
working capital requirements and developing a customer base, among others. If we are not effective in addressing these risks, we will not be able to operate profitably in the
future, and we may not have adequate working capital to meet our obligations as they become due.

Our business may be adversely affected by a global economic downturn.

Any economic downturn generally could cause a drop in government spending and business investment, which could have a material adverse effect on our business.
Further, as a result of the current global economic situation, there may be a disruption or delay in performance by our third-party contractors and suppliers. If such third parties
are unable to adequately satisfy their contractual commitments to us in a timely manner, our business could be adversely affected.

We could incur significant damages if we are unable to adequately discharge our contractual obligations.

Our failure to comply with contract requirements or to meet our clients’ performance expectations on a contract could materially and adversely affect our financial
performance and our reputation. This, in turn, would impact our ability to compete for new clients and contracts. Our failure to meet contractual obligations could also result in
substantial  actual  and  consequential  damages  under  the  terms  of  such  contracts.  In  addition,  some  of  our  contracts  require  us  to  indemnify  clients  for  our  failure  to  meet
performance standards and/or contain liquidated damages provisions and financial penalties related to performance failures. Although we do have liability insurance, the policy
limits may not be adequate to provide protection against all such potential liabilities.

Some of our clients may terminate our contracts prior to completion, which could result in revenue shortfalls and reduce profitability or cause losses on contracts.

Our small number of our contracts with clients contain initial or base periods of one or more years, as well as option periods typically covering more than one-half of
the contract’s initial duration. However, such clients are under no obligation to exercise the option to extend the contract term. The profitability of some of our contracts could
be adversely impacted if such options are not exercised and the contract term is not extended accordingly. Additionally, our contracts contain provisions permitting a client to
terminate  the  contract  on  short  notice,  with  or  without  cause.  The  unexpected  termination  of  significant  contracts  could  result  in  significant  revenue  shortfalls.  If  revenue
shortfalls occur and are not offset by corresponding reductions in expenses, our business could be adversely affected. We cannot anticipate if, when or to what extent a client
might terminate its contracts with us.

We are subject to government audits, and our failure to comply with applicable laws, regulations and standards could subject us to civil and criminal penalties and
administrative sanctions.

The  government  agencies  we  contract  with  have  the  authority  to  audit  and  investigate  our  contracts  with  them. As  part  of  that  process,  a  government  agency  may
review our performance on a contract, our pricing practices, our cost structure and our compliance with applicable laws, regulations and standards. If the agency determines that
we have improperly allocated costs to a specific contract, we will not be reimbursed for those costs and we will be required to refund the amount of any such costs that have
been previously reimbursed. If a government audit identifies improper activities by us or we otherwise determine that these activities have occurred, we could be subject to civil
and criminal penalties and administrative sanctions, including termination of contracts, forfeitures of profits, suspension of payments, fines and suspension or disqualification
from doing business with the government. Any adverse determination could adversely impact our ability to bid for Request for Proposals (“RFPs”) in one or more jurisdictions.

We may not be able to effectively control and manage our growth, which would negatively impact our operations.

We  have  operated  our  current  line  of  business  for  approximately  seven  years,  and  we  expect  to  grow  in  the  near  future  as  our  business  develops  and  becomes
established. If our business grows as we anticipate, it will be necessary for us to manage our expansion in an orderly fashion. Any significant growth in our activities or in the
market  for  our  services  will  require  extension  of  our  managerial,  operational,  marketing  and  other  resources.  Future  growth  will  also  impose  significant  additional
responsibilities upon the members of management to identify, recruit, maintain, integrate, and motivate new employees. Our failure to manage growth effectively may lead to
operational  inefficiencies  that  will  have  a  negative  effect  on  our  profitability. Additionally,  if  our  growth  comes  at  the  expense  of  providing  quality  service  and  generating
reasonable profits, our ability to successfully bid for contracts and our profitability will be adversely affected. We cannot assure investors that we will be able to effectively
manage any future growth we may experience.

Failure to obtain adequate insurance coverage could put us at risk for uninsured losses.

Some or all of our customers may require insurance as a requirement to conduct business with us. Although we currently have liability insurance, we may be unable to
obtain or maintain adequate liability insurance on acceptable terms, if at all, and there is a risk that our insurance will not provide adequate coverage against our potential losses.
Additionally, there are certain types of losses that may not be insurable at a cost that we can afford, and insurance may not be available at any cost with respect to certain losses.
Claims or losses in excess of any insurance coverage we may obtain, or the lack of insurance coverage, could put us at risk of loss for any uninsured loss, which would have a
material adverse effect on our business and financial condition.

We are dependent on our Interim Chief Executive Officer and other key personnel, and the loss of any of these individuals could harm our business.

We  depend  on  John  Rice,  our  interim  Chief  Executive  Officer,  as  well  as  key  scientific  and  other  personnel.  The  loss  of  any  of  these  individuals  could  harm  our
business and significantly delay or prevent the achievement of our business objectives. In addition, our delivery of services will be labor-intensive: when we are awarded a
contract, we may need to quickly hire project leaders and project management personnel. The additional staff may also create a concurrent demand for increased administrative
personnel. The success of our business will require that we attract, develop, motivate and retain:

●

●

●

experienced and innovative executive officers;

senior managers who have successfully managed or designed programs in the public sector; and

information technology professionals who have designed or implemented complex information technology projects.

Innovative, experienced and technically proficient individuals are in great demand and are likely to remain a limited resource. We may be unable to continue to attract
and  retain  desirable  executive  officers,  senior  managers,  and  technology  professionals.  Our  inability  to  hire  sufficient  personnel  on  a  timely  basis  or  the  loss  of  significant
numbers of executive officers and senior managers could adversely affect our business.

We may be dependent on cash flow and payments from customers in order to meet our expense obligations.

A number of factors may cause our revenues, cash flow and operating results to vary from quarter to quarter, including the following:

●

●

●

●

●

●

the progression of contracts;

the levels  of  revenues  earned  on  fixed-price  and  performance-based  contracts  (including  any  adjustments  in  expectations  for  revenue recognition  on  fixed-price
contracts);

the commencement, completion or termination of contracts during any particular quarter;

the schedules of government agencies and large multinational corporations for awarding contracts;

the failure of our customers to fulfill their obligations under contracts with us; and

the term of awarded contracts and potential acquisitions.

Changes in the volume of activity and the number of contracts commenced, completed or terminated during any quarter may cause significant variations in our cash
flow from operations because a significant portion of our expenses are fixed. Fixed expenses include, rent, payroll, insurance, employee benefits, taxes and other administrative
costs  and  overhead.  Moreover,  we  expect  to  incur  significant  operating  expenses  during  the  start-up  and  early  stages  of  large  contracts  and  typically  do  not  receive
corresponding payments in that same quarter.

We may make acquisitions in the future that we are unable to effectively manage given our limited resources.

We may choose to grow our business by acquiring other entities. We may be unable to manage businesses that we have acquired or to integrate them successfully
without incurring substantial expenses, delays or other problems that could negatively impact our results of operations. Moreover, business combinations involve additional
risks, including:

●

●

●

●

●

●

●

diversion of management’s attention;

loss of key personnel;

our becoming significantly leveraged as a result of the incurrence of debt to finance an acquisition;

assumption of unanticipated legal or financial liabilities;

unanticipated operating, accounting or management difficulties in connection with the acquired entities;

amortization of acquired intangible assets, including goodwill; and

dilution to existing stockholders and our earnings per share.

Also,  client  dissatisfaction  or  performance  problems  with  an  acquired  firm  could  materially  and  adversely  affect  our  reputation  as  a  whole.  Further,  the  acquired

businesses may not achieve the revenues and earnings that we anticipated.

We may be unable to develop or commercialize new and rapidly evolving technologies.

Many  of  our  activities  involve  developing  products  or  processes  that  are  based  upon  new,  rapidly  evolving  technologies.  The  ability  to  commercialize  or  further

develop these technologies could fail for a variety of reasons, both within and outside of our control.

We may be unable to protect our intellectual property rights.

Our success in part depends on the ability to protect our intellectual property and proprietary technology. To do so, we will be required to prosecute patent applications
and maintain patents, obtain new patents and pursue trade secret and other intellectual property protection. We were awarded two U.S. patents with respect to our munitions
technology. We were also awarded a U.S. patent with respect to our IPQA® technology. In addition, we filed eighteen foreign and U.S. patent applications pertaining to our
IPQA®  technology  and  rapid  qualification  of  additive  manufacturing  for  metal  parts. Also,  we  filed  a  PCT  patent  application  pertaining  to  the  advanced  dental  implant
technology. However, the efforts we have taken to protect our proprietary rights may not be sufficient or effective.  There can be no assurance that our program for protection of
intellectual property and proprietary technology will be sufficient to protect our intellectual property and proprietary technology from  competitors. Our business is also subject
to the risk that our issued patents will not provide us with significant competitive advantages if, for example, a competitor were to independently develop or obtain similar or
superior  technologies.  In  addition,  our  issued  patents  may  be  challenged  or  infringed  upon  by  third  parties.  The  enforcement  of  intellectual  property  rights  is  subject  to
considerable uncertainty, and can be expensive and time-consuming. Patent reform laws and court decisions interpreting such laws, may create additional uncertainty around
our  ability  to  obtain  and  enforce  patent  protection. Any  significant  impairment  of  our  intellectual  property  rights  could  harm  our  business  and  our  ability  to  compete.  The
unauthorized use of our intellectual property could make it more expensive to do business and harm our operating results. Proprietary trade secrets and unpatented know-how
are  also  very  important  to  our  business,  however,  trade  secrets  are  difficult  to  protect.  Our  employees,  consultants,  contractors,  outside  scientific  collaborators  and  other
advisors may unintentionally or willfully disclose our confidential information to competitors, and confidentiality agreements may not provide an adequate remedy in the event
of unauthorized disclosure of confidential or proprietary information.

We may be sued by third parties who claim that we have infringed their intellectual property rights.

We  may  be  exposed  to  future  litigation  by  third  parties  based  on  claims  that  our  research,  development  and  commercialization  activities  infringe  the  intellectual
property rights of third parties to which we do not hold licenses or other rights, or that we have misappropriated the trade secrets of others. Any litigation or claims against us,
whether or not valid, could result in substantial costs, and could place a significant strain on our financial and human resources. In addition, if successful, such claims could
cause us to pay substantial damages. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that
some of our confidential information could be compromised by disclosure during this type of litigation.

Our services are subject to government regulation, changes in which may have an adverse effect on us.

Our business activities subject us to a variety of federal, state and local laws and regulations. For example, we will required to comply with applicable provisions of the
International Traffic in Arms Regulations (“ITAR”), as well as other export controls and laws governing the manufacture and distribution of munitions technology. Despite the
fact  that  we  have  applied  for  and  received  ITAR  compliance,  changes  in  the  laws  and  regulations  applicable  to  our  business  activities  may  have  an  adverse  effect  on  our
operations and profitability by making it more expensive and less profitable for us to do business. Additionally, the market for our services depends largely on federal and state
legislative programs. These programs can be modified or amended at any time by acts of federal and state governments. Further, if additional programs are not proposed or
enacted, or if previously enacted programs are challenged, repealed or invalidated, our growth strategy could be adversely impacted.

Our bylaws contain provisions indemnifying our officers and directors against all costs, charges, and expenses incurred by them.

Our Bylaws contain provisions with respect to the indemnification of our officers and directors against all costs, charges and expenses actually and reasonably incurred
by an officer or director paid to settle an action or satisfy a judgment in a civil, criminal or administrative action or proceeding to which he is made a party by reason of being or
having been one of our directors or officers. To the extent that our directors’ and officers’ insurance policy does not provide reimbursement for such costs, charges, expenses
and other amounts, we may incur substantial expenses in satisfying our indemnification obligations.

Our operating costs could be significantly higher than we expect, and this could reduce our future profitability.

In addition to general economic conditions, market fluctuations and international risks, significant increases in operating, development and implementation costs could

adversely affect us due to numerous factors, many of which are beyond our control.

A cyber incident could result in information theft, data corruption, operational disruption and/or financial loss. 

Businesses  have  become  increasingly  dependent  on  digital  technologies  to  conduct  day-to-day  operations. At  the  same  time,  cyber  incidents,  including  deliberate
attacks or unintentional events, have increased. A cyber-attack could include gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive
information, corrupting data, or causing operational disruption or result in denial of service on websites. We depend on digital technology, including information systems and
related infrastructure, to process and record financial and operating data, and communicate with our employees and business partners. Our technologies, systems, networks, and
those  of  our  business  partners  may  become  the  target  of  cyber-attacks  or  information  security  breaches  that  could  result  in  the  unauthorized  release,  gathering,  monitoring,
misuse, loss or destruction of proprietary and other information, or other disruption of our business operations. Although to date we have not experienced any losses relating to
cyber-attacks, there is no assurance that we will not suffer such losses in the future. As cyber threats continue to evolve, we may be required to expend significant additional
resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities.

Risks Related to Our Securities

The price of our securities could be subject to volatility related or unrelated to our operations, which could result in substantial losses for our stockholders.

Between January 1, 2016 and December 31, 2017, the trading price of our common stock has ranged from a low of $1.33 to a high of $12.00, and could be subject to
wide  fluctuations  in  the  future  in  response  to  various  factors,  some  of  which  are  beyond  our  control.  The  trading  price  of  the  warrants  that  we  issued  in  our  recent  public
offering could be subject to similar fluctuations as a result of such factors. These factors include those discussed previously in this “Risk Factors” section and others, such as:

●

●

●

●

●

●

●

delays or failures in the commercialization of our current or future products and services;

quarterly variations in our results of operations or those of our competitors;

changes in our earnings estimates or recommendations by securities analysts or adverse publicity about us or our products or services;

announcements by us or our competitors of new products and services, significant contracts, commercial relationships, acquisitions or capital commitments;

adverse developments with respect to our intellectual property rights;

commencement of litigation involving us or our competitors;

any major changes in our board of directors or management;

● market conditions in our industry; and

●

general economic conditions in the United States and abroad.

In addition, the stock market, in general, may experience broad market fluctuations, which may adversely affect the market price or liquidity of our securities.

We could be subject to securities class action litigation.

Any sudden decline in the market price of our securities could trigger securities class action lawsuits against us. If any of our stockholders were to bring such a lawsuit
against us, we could incur substantial costs defending the lawsuit and the time and attention of our management would be diverted from our business and operations. We also
could be subject to damages claims if we are found to be at fault in connection with a decline in our market price of our securities.

An active trading market in our securities may not develop, and you may therefore have difficulty selling your securities at a price that you determine is satisfactory.

Although  our  common  stock  and  the  2017  warrants  are  listed  on  The  NASDAQ  Capital  Market,  our  common  stock  and  warrants  trade  infrequently  and  in  low
volumes. There is no assurance that such securities will trade in the public market at or above a price that you consider acceptable. Furthermore, there is no assurance that an
active trading market for any of our securities will develop or be sustained. If an active market for our securities does not develop or is not maintained, it may be difficult for
you to sell your securities when you wish to sell them or at a price that you consider satisfactory. An inactive trading market may also impair our ability to raise capital to
continue to fund operations by selling securities and may impair our ability to acquire other companies or technologies by using our securities as consideration.

There is no assurance that we will satisfy the continued listing requirements of The NASDAQ Capital Market.

Even though our common stock and 2017 warrants are listed on The NASDAQ Capital Market, we cannot assure you that we will be able to satisfy the continued
listing requirements of The NASDAQ Capital Market. For example, there is no assurance that our common stock will continue to have a bid price of at least $1.00 per share,
which  is  the  minimum  bid  price  under  such  continued  listing  requirements,  or  that  we  will  be  able  to  satisfy  other  quantitative  continued  listing  requirements  such  as  the
requirement for us to have stockholders’ equity of at least $2.5 million. If our securities are de-listed from The NASDAQ Capital Market, our stockholders could incur material
adverse  consequences  such  as  reduced  liquidity  for  their  securities  and  reduced  market  prices  for  their  securities.  Following  such  de-listing,  we  could  encounter  increased
difficulty in issuing additional securities at an attractive price, or at all, in order to fund our operations.

You may experience additional dilution as a result of future equity offerings.

In  order  to  raise  additional  capital,  we  may  in  the  future  offer  additional  shares  of  our  common  stock  or  other  securities  convertible  into  or  exchangeable  for  our
common stock. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions
may be lower than the price per share that you paid for our common stock.

We have broad discretion in the use of the net proceeds of our recent public and private offerings and may not use them effectively.

We  intend  to  use  our  cash  for  the  development  of  our  products  and  service  and  to  repay  our  outstanding  promissory  note  (if  and  to  the  extent  the  holder  thereof
demands repayment). We may also use a portion of the net proceeds from our February 2017 and April 2018 offerings to acquire other products or businesses, although we are
not currently a party to an agreement regarding any such acquisition. However, our management has broad discretion in the use of cash and will have the right to use our cash in
ways  that  differ  substantially  from  our  current  plans.  Management  may  spend  our  cash  in  ways  that  do  not  improve  our  results  of  operations  or  enhance  the  value  of  our
securities. The failure by management to apply funds effectively could result in financial losses that could have a material and adverse effect on our business and cause the
market price of our securities to decline.

We do not intend to pay dividends on our common stock, and your ability to achieve a return on your investment will depend on appreciation in the market price of
our securities.

We currently intend to invest our future earnings, if any, to fund our growth and not to pay any cash dividends on our common stock. Since we do not intend to pay
dividends,  your  ability  to  receive  a  return  on  your  investment  will  depend  on  any  future  appreciation  in  the  market  price  of  our  securities.  There  is  no  assurance  that  our
securities will appreciate in price.

If  securities  or  industry  analysts  do  not  publish  research  or  reports  about  us,  or  if  they  issue  adverse  or  misleading  opinions  regarding  us  or  our  securities,  the
market price of our securities and their trading volume could decline.

If we do not obtain and maintain research coverage by securities and industry analysts, the market price for our securities may be adversely affected. The market price
of  our  securities  also  may  decline  if  any  analyst  who  covers  us  issues  an  adverse  or  erroneous  opinion  regarding  us,  our  business  model,  our  intellectual  property  or  our
performance. If one or more analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause the
market price of our securities and their trading volume to decline and possibly adversely affect our ability to engage in future financings.

Our principal stockholders and management own a significant percentage of our common stock and may be able to significantly affect matters subject to stockholder
approval.

Based on shares outstanding as of December 31, 2017, our executive officers, directors, holders of 5% or more of our common stock and their respective affiliates will
beneficially  own  in  the  aggregate  approximately  13.62%  of  our  outstanding  shares  of  common  stock. As  a  result  of  their  stock  ownership,  these  stockholders  will  have  the
ability  to  influence  our  management  and  policies,  and  are  able  to  materially  affect  the  outcome  of  matters  requiring  stockholder  approval  such  as  elections  of  directors,
amendments  of  our  organizational  documents  or  approvals  of  any  merger,  sale  of  assets  or  other  major  corporate  transaction.  This  may  prevent  or  discourage  unsolicited
acquisition proposals or offers for our common stock that you may feel are in your best interest as one of our stockholders.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders
of a large number of shares intend to sell shares, could  reduce  the  market  price  of  our  common  stock. As  of  December  31,  2017,  we  have  4,978,929  outstanding  shares  of
common stock. Sales of a large number of the shares described in the preceding sentence, or the perception that a large number of shares may be sold, could have a material
adverse effect on the trading price of our common stock.

We will incur significant costs to ensure compliance with U.S. and NASDAQ reporting and corporate governance requirements.

We will incur significant costs associated with our public company reporting requirements and with applicable U.S. and NASDAQ corporate governance requirements,
including requirements under the Sarbanes-Oxley Act of 2002 and other rules implemented by the SEC and NASDAQ. We expect all of these applicable rules and regulations
to significantly increase our legal and financial compliance costs and to make some activities more time consuming and costly. We also expect that these applicable rules and
regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and
coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve
on our board of directors or as executive officers.

If we fail to maintain effective internal control over financial reporting, the market price of our securities may be adversely affected.

As a public reporting company, we are required to establish and maintain effective internal control over financial reporting. Failure to establish such internal control, or
any failure of such internal control once established, could adversely impact our public disclosures regarding our business, financial condition or results of operations. Any
failure  of  our  internal  control  over  financial  reporting  could  also  prevent  us  from  maintaining  accurate  accounting  records  and  discovering  accounting  errors  and  financial
frauds.

Rules adopted by the SEC pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 require annual assessment of our internal control over financial reporting. The
standards that must be met for management to assess the internal control over financial reporting as effective are complex, and require significant documentation, testing and
possible remediation to meet the detailed standards. We may encounter problems or delays in completing activities necessary to make an assessment of our internal control over
financial reporting. If we cannot assess our internal control over financial reporting as effective, investor confidence and share value may be negatively impacted. In addition,
management’s assessment of internal control over financial reporting may identify weaknesses and conditions that need to be addressed in our internal control over financial
reporting  or  other  matters  that  may  raise  concerns  for  investors. Any  actual  or  perceived  weaknesses  and  conditions  that  need  to  be  addressed  in  our  internal  control  over
financial reporting (including those weaknesses identified in our periodic reports), or disclosure of management’s assessment of our internal control over financial reporting
may have an adverse impact on the price of our securities.

Provisions  in  our  articles  of  incorporation  and  bylaws  could  discourage  a  takeover  that  stockholders  may  consider  favorable  and  may  lead  to  entrenchment  of
management.

Our articles of incorporation and bylaws contain provisions that could delay or prevent changes in control or changes in our management without the consent of our

board of directors. These provisions include the following:

●

●

●

●

●

●

●

●

●

a classified  board  of  directors  with  three-year  staggered  terms,  which  may  delay  the  ability  of  stockholders  to  change  the  membership of  a  majority  of  our  board  of
directors;

no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;

the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a
director, which prevents stockholders from being able to fill vacancies on our board of directors;

the ability of our board of directors to authorize the issuance of additional shares of preferred stock and to determine the terms of those shares, including preferences and
voting  rights,  without  stockholder  approval,  which  could  adversely  affect  the  rights of  our  common  stockholders  or  be  used  to  deter  a  possible  acquisition  of  our
company;

the ability of our board of directors to alter our bylaws without obtaining stockholder approval;

the required approval of the holders of at least two-thirds of the shares entitled to vote at an election of directors to adopt, amend or repeal our bylaws or repeal the
provisions of our articles of incorporation and bylaws regarding the election and removal of directors;

a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

the requirement that a special meeting of stockholders may be called only by the chairman of the board of directors, the chief executive officer, the president or the board
of directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors; and

advance notice  procedures  that  stockholders  must  comply  with  in  order  to  nominate  candidates  to  our  board  of  directors  or  to  propose matters  to  be  acted  upon  at  a
stockholders’  meeting,  which  may  discourage  or  deter  a  potential  acquirer  from  conducting a  solicitation  of  proxies  to  elect  the  acquirer’s  own  slate  of  directors  or
otherwise attempting to obtain control of us.

These provisions could inhibit or prevent possible transactions that some stockholders may consider attractive.

Our  board  has  recently  issued  a  Series  B  Preferred  Stock  and  could  issue  one  or  more  additional  series  of  preferred  stock  with  the  effect  of  diluting  existing
stockholders and impairing their voting and other rights.

Our articles of incorporation authorizes the issuance of up to 10,000,000 shares of “blank check” preferred stock with designations, rights and preferences as may be
determined from time to time by our board of directors. In our April 6, 2018 private placement of equity securities, we issued 1,000 shares of Series B Preferred Stock, which
are initially convertible into 1,000,000 shares of common stock. Our board is empowered, without stockholder approval, to issue one or more additional series of preferred stock
with dividend, liquidation, conversion, voting or other rights which could dilute the interest of, or impair the voting power of, our common stockholders. The issuance of such
additional series of preferred stock could be used as a method of discouraging, delaying or preventing a change in control. For example, it would be possible for our board of
directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to effect a change in control of our Company.

expires on September 30, 2018.

We believe that our facilities are suitable for our current needs.

 ITEM 3. LEGAL PROCEEDINGS.

We are not currently a party to any legal proceedings. However, we may occasionally become subject to legal proceedings and claims that arise in the ordinary course
of our business. It is impossible for us to predict with any certainty the outcome of pending disputes, and we cannot predict whether any liability arising from pending claims
and litigation will be material in relation to our financial position or results of operations.

Dividends

We  have  not  paid  any  dividends  on  our  common  stock  to  date  and  do  not  anticipate  that  we  will  pay  dividends  in  the  foreseeable  future. Any  payment  of  cash
dividends on our common stock in the future will be dependent upon the amount of funds legally available, our earnings, if any, our financial condition, our anticipated capital
requirements and other factors that the board of directors may think are relevant. However, we currently intend for the foreseeable future to follow a policy of retaining all of
our earnings, if any, to finance the development and expansion of our business and, therefore, do not expect to pay any dividends on our common stock in the foreseeable future.

Recent Sales of Unregistered Securities

On October 6, 2017, pursuant to an advisory agreement with the underwriter of our most recent public offering, we issued such underwriter a total of 141,000 shares of
our common stock in exchange for the surrender by such underwriter of its Unit Purchase Option to acquire up to 70,500 Units. The foregoing shares were issued in reliance
upon an exemption from the registration requirements pursuant to Section 3(a)(9)of the Securities Act

In December 2017, we issued a total of 260,278 shares of our common stock to two investors upon conversion and exercise of a portion of the convertible notes and
warrants, respectively held by such investors. The foregoing securities were issued in reliance upon an exemption from the registration requirements pursuant to Section 4(2) of
the Securities Act.

Repurchase of Shares

We did not repurchase any of our securities during the fiscal year ended December 31, 2017.

 ITEM 6. SELECTED FINANCIAL DATA.

Not applicable to a “smaller reporting company” as defined in Item 10(f)(1) of SEC Regulation S-K.

 ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Critical Accounting Policies

The 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 assets, liabilities, sales and expenses in the accompanying financial statements. 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. Such critical accounting policies, including the
assumptions and judgments underlying them, are disclosed in Note 1 to the Financial Statements included in this Annual Report. 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.

Results of Operations

Year Ended December 31, 2017 Compared to the Year Ended December 31, 2016.

We expect to generate revenue primarily by selling and licensing our IPQA technologies, selling technical support services and contract manufacturing and selling
specialty parts and studies to businesses that seek to improve their manufacturing production processes and production-run quality yields. Our ability to generate revenues in the
future will depend on our ability to further commercialize and increase market presence of our PrintRite3D® technologies, and it will depend on if key prospective customers
continue to move from AM metal prototyping to production.

During the fiscal year ended December 31, 2017 (“fiscal 2017”), we generated an aggregate of $641,049 in revenues, as compared to an aggregate of $966,422 in
revenues  generated  by  us  in  the  fiscal  year  ended  December  31,  2016  (“fiscal  2016”).  The  decrease  in  revenue  was  primarily  due  to  the  strategic  reorganization  of  the
Company’s priorities and personnel over the second six months of 2017. The Company determined that it was essential to transform Sigma from being an R&D company into
being a technology development and commercialization company. This imperative and the many changes required to implement it derived from the observation that the R&D
culture could not meet the demonstrated needs of both new and prospective customers for practical solutions to problems they have now and for technical product introduction
processes to support and educate on how to take advantage of the Company’s technology. Commencing in the summer of 2017, the Company began a rapid shift away from
selling and supporting single PrintRite3D® units to customers who currently focus on R&D and have no material production of AM parts (and thus, have no near term need to
buy  more  PrintRite3D®  units).  By  September  1,  2017,  the  Company  strategy  led  to  a  policy  requiring  100%  sales  and  marketing  focus  on  prospective  customers  who  are
already producing AM metal parts in production runs, who realize they have low yields and, in some cases, worry that perhaps they are unwittingly shipping parts that are
invisibly  below  specification.  Concurrent  with  this  new  policy  of  customer  focus,  the  Company  worked  to  integrate  sales  and  marketing  more  closely  with  product
development. This integration included creating a dedicated Sigma customer support team for in-field hands-on support of PrintRite3D® assessments and demonstrations to
enable  Sigma  and  its  newly  targeted  customer  group  to  cooperate  in  a  simple  defined  process  that  provides  customers  with  a  demonstration  of  how  to  calibrate  their AM
equipment using PrintRite3D® and how to improve quality using PrintRite3D®, as substantiated by using a third party laboratory to affirm, part by part, the quality test results.
We  generated  revenues  and  financed  our  operations  in  fiscal  2017  and  fiscal  2016  primarily  from  engineering  consulting  services  we  provided  to  third  parties  during  these
periods  and  through  sales  of  our  common  stock  and  debt  securities.  We  expect  that  our  revenue  will  increase  in  future  periods  as  we  seek,  as  discussed  above,  to  further
commercialize and expand our market presence for our PrintRite3D®-related technologies, and obtain new contract manufacturing orders in connection with our EOS M290,
and continue to provide our services under our contracts with Honeywell Aerospace for the DARPA Period 2 program.

Sigma’s operating expenses for fiscal 2017 were $4,420,667 as compared to $3,211,258 for fiscal 2016. Our operating expenses principally include internal operating
and  sales  expenses,  outside  service  fees,  and  research  &  development  costs.  These  three  operating  expense  areas  are  responsible  for  $1,133,513  or  94%  of  the  increased
operating costs in 2017.

Personnel costs, specifically the payroll and stock-based compensation components of personnel costs, are the most significant component of the Company’s internal
operating expenses. In fiscal 2017, payroll costs were $1,269,476 as compared to $1,027,306 for the same period in 2016. This increase in payroll was primarily due to the
increased salaries associated with the strategic new hires and reorganization of the management team made in the second half of the year. Expenses relating to stock-based
compensation for year ended December 31, 2017 were $719,796 as compared to $341,558 for the same period in 2016. This increase in stock-based compensation costs resulted
both from the fact that the majority of stock options were granted after September 30, 2016, thus significantly more stock option vesting amortization was recorded in the four
quarters comprising fiscal 2017 than in the same periods of 2016  and  from  the  grant  of  a  significant  number  of  options  with  shorter  vesting  periods  as  part  of  the  strategic
realignment of key personnel in mid-2017. This expense also includes the amortization of stock issued for prepaid services.

Outside Services Fees paid in 2017 were $1,229,304 compared to $934,839 paid in 2016. In each year, services in connection with our obligations as an SEC reporting
company cost us slightly over $550,000. However, other legal fees of $333,046 were paid in 2017 compared to $126,992 in 2016. The increase in these fees was primarily from
those paid conjunction with our February 2017 public offering that resulted in net proceeds of approximately $5,225,650. In addition outside service expenditures related to
advertising and trade show activities were up by $59,294 as a result of our shift in strategic focus toward scalable commercial rather than programmatic business development.

Research and Development expenditures were $302,043 in 2017 compared to $120,638 in 2016. This $181,405 increase resulted primarily from the additional R&D

consulting costs incurred as part of our concentrated acceleration of technology development in 2017.

In 2017, our Net Other Income & Expense was a net expense of $525,526 compared to net income of $276,904 in 2016. The largest contributor to the 2017 loss was
$545,188 due to revaluations of derivatives and amortization of debt discounts required as a result of February 2017 public offering, the restructuring of debt in October 2017,
and the December 2017 conversions by two debt instrument holders. This compares to a $354,644 positive contribution from revaluation of derivatives in 2016. Offsetting these
noncash adjustments was positive contribution in 2017 from an $102,865 increase in the amount of cash incentives received from the State of New Mexico and $40,107 of
interest income earned on loans we made. These were largely offset by a $121,624 increase in interest expense on the $1,000,000 note originated in October of 2016.

Sigma’s  net  loss  for  fiscal  2017  increased  $2,380,682  overall  and  totaled  $4,577,516,  as  compared  to  $2,196,834  for  fiscal  2016.  The  2017  net  operating  loss

component of the overall loss being $1,578,252 higher than in 2016 and the other income and expenses component being a $802,430 higher loss.

Liquidity and Capital Resources

As of December 31, 2017, we had $1,515,674 in cash and a working capital surplus of $2,273,801, as compared to $398,391 in cash and a working capital surplus of
$110,799 as of December 31, 2016. On March 28, 2018, Sigma received $535,000 in full payment of the outstanding Morf3D note receivable and accrued interest. On April 6,
2018,  the  Company  closed  a  private  placement  of  equity  securities  resulting  in  net  proceeds  of  approximately  $840,000,  after  deducting  commissions  and  other  offering
expenses payable by the Company.

During the remainder of 2018, we expect to further ramp up our operations and our commercialization and marketing efforts, which will increase the amount of cash
we  will  use  in  our  operations.  We  expect  that  our  continued  development  of  our  IPQA®-enabled  PrintRite3D®  technology  will  enable  us  to  further  commercialize  this
technology for the AM metal market in 2018. However, until commercialization of our full suite of PrintRite3D® technologies, we plan to continue funding our development
activities  and  operating  expenses  by  licensing  our  PrintRite3D®  systems  and  supporting  field  services,  as  applicable,  and  providing  PrintRite3D®-enabled  engineering
consulting services concerning our areas of expertise (materials and manufacturing quality assurance and process control technologies) and contract manufacturing for metal
AM, and through the use of proceeds from sales of our securities.

Cash used in operating activities in 2017 increased to $2,791,406 from $1,962,314 in 2016 due primarily to increases in payroll, and in outside services costs related to
both the $5,250,000 capital raise and increased research and development activities in 2017. The Company anticipates fewer losses in 2018, due to expected increased revenues,
offset  by  increased  salaries  and  related  expenses  in  connection  with  additional  employees  and  potential  acquisitions  (although  there  are  no  agreements  with  respect  to  the
acquisition by the Company of any third party, and there can be no assurance that any agreements will be entered into or, if entered into, that any acquisition or other transaction
will be consummated). Cash flows used in investing activities increased from $79,104 in 2016 to $928,960 in 2017 primarily due to the layout of $788,500 in exchange for notes
receivable issued to two customers in 2017. Cash flows provided by financing activities in 2017 were $4,837,649 compared to $900,000 in 2016. The increase resulted from the
issuance  of  shares  of  common  stock  and  warrants  in  February  2017  that  raised  net  proceeds  of  $5,250,000  and  the  exercise  of  warrants  in  December  2017  that  raised  an
additional  $112,000  in  proceeds,  offset  by  $500,000  principal  payments  on  debt  securities  in  October  2017  as  opposed  to  net  proceeds  of  $900,000  raised  in  October  2016
through a private offering of debt securities.

We have no credit lines as of April 10, 2018, nor have we ever had a credit line since our inception.

Based on the funds we have as of April 10, 2018, and the proceeds we expect to receive under our PrintRite3D®-enabled engineering consulting agreements, from
selling or licensing our PrintRite3D® systems and software, sales of contract AM manufacturing for metal AM parts and the payment of loans made by Sigma, we believe that
we  will  have  sufficient  funds  to  pay  our  administrative  and  other  operating  expenses  through  2018.  Until  we  are  able  to  generate  significant  revenues  and  royalties  from
licensing our PrintRite3D®-enabled technologies and our contact AM manufacturing services, our ability to continue to fund our liquidity and working capital needs will be
dependent  upon  revenues  from  existing  and  future  PrintRite3D®-enabled  engineering  consulting  contracts,  possible  strategic  partnerships,  contract  manufacturing  orders  in
connection  with  our  EOS  M290,  and  proceeds  received  from  sales  of  our  debt  and/or  securities. Accordingly,  we  may  have  to  obtain  additional  capital  from  the  sale  of
additional securities or by borrowing funds from lenders to fulfill our business plans. If we issue additional equity or debt securities, stockholders may experience additional
dilution or the new equity securities may have rights, preferences or privileges senior to those of existing holders of our common stock. There is no assurance that we will be
successful  in  obtaining  additional  funding.  If  we  fail  to  obtain  sufficient  funding  when  needed,  we  may  be  forced  to  delay,  scale  back  or  eliminate  all  or  a  portion  of  our
commercialization efforts and operations.

Inflation and changing prices have had no effect on our continuing operations over our two most recent fiscal years.

We have no off-balance sheet arrangements as defined in Item 303(a) of Regulation S-K.

 ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Rule 13a-15(e) under the Exchange Act defines the term “disclosure controls and procedures” as those controls and procedures designed to ensure that information
required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods
specified in the SEC rules and forms and that such information is accumulated and communicated to the company’s management, including its principal executive and principal
financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Based upon an evaluation of the effectiveness of our disclosure controls and procedures performed by our management, with the participation of our Interim Chief
Executive  Officer,  and  Chief  Financial  Officer  (Principal  Financial  and Accounting  Officer),  as  of  the  end  of  the  period  covered  by  this  annual  report,  our  management
concluded that our disclosure controls and procedures are effective at a reasonable assurance level in ensuring that information required to be disclosed by us in our reports is
recorded, processed, summarized and reported within the required time periods. The foregoing conclusion is based, in part, on the fact that we are a small public company in the
early stage of our business, with limited revenues and employees.

Management’s Annual Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f)
under  the  Exchange  Act.  Our  management,  with  the  participation  of  our  Interim  Chief  Executive  Officer,  and  Chief  Financial  Officer,  conducted  an  evaluation  of  the
effectiveness of our control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of
the Treadway Commission. Based on management’s evaluation under the framework, management has concluded that our internal control over financial reporting was effective
as of December 31, 2017.

We  continuously  seek  to  improve  and  strengthen  our  control  processes  to  ensure  that  all  of  our  controls  and  procedures  are  adequate  and  effective. Any  failure  to
implement  and  maintain  improvements  in  the  controls  over  our  financial  reporting  could  cause  us  to  fail  to  meet  our  reporting  obligations  under  the  SEC’s  rules  and
regulations. Any  failure  to  improve  our  internal  controls  to  address  the  weakness  we  have  identified  could  also  cause  investors  to  lose  confidence  in  our  reported  financial
information, which could have a negative impact on the trading price of our common stock.

This  annual  report  does  not  include  an  attestation  report  of  the  Company’s  registered  public  accounting  firm  regarding  internal  control  over  financial  reporting.
Management’s report was not subject to attestation by our registered public accounting firm pursuant to SEC rules that permit us to provide only management’s report in this
annual report.

There  have  been  no  changes  in  our  internal  controls  over  financial  reporting  during  the  fourth  quarter  of  the  year  ended  December  31,  2017  that  have  materially

affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Our  Board  of  Directors  believes  that  Mr.  Rice  is  qualified  to  serve  as  a  member  of  the  board  because  of  his  broad  and  deep  experience  in  improving  business

operations, engineering financial structures that support ongoing needs of operating companies, and building investor and shareholder values.

Salvatore  Battinelli was  appointed  to  our  Board  of  Directors  on August  16,  2017.  Mr.  Battinelli  is  currently  the  President  and  Chief  Executive  Officer  of  Bello  e

expertise in business management, finance and strategic planning.

Director Independence

Our Board of Directors currently consists of five members. As a result of his appointment as interim Chief Executive Officer, Mr. Rice is no longer considered an
independent director, and Mr. Garofalo is no longer considered an independent director because on August 8, 2017 we engaged Garofalo & Associates, LLC, a limited liability
company owned and controlled by Mr. Garofalo, to provide services to the Company as corporate development consultant and financial advisor. Our Board of Directors has
determined that our other directors, Salvatore Battinelli, Dennis Duitch and Kent Summers, constituting a majority of our directors, are “independent” as that term is defined
under Rule 5605(a)(2) of the NASDAQ marketplace rules. Pursuant to NASDAQ rules, our board must consist of a majority of independent directors.

The  NASDAQ  independence  definition  includes  a  series  of  objective  tests,  including  that  the  director  is  not,  and  has  not  been  for  at  least  three  years,  one  of  our
employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by NASDAQ rules,
our Board of Directors has made a subjective determination as to Messrs. Battinelli, Duitch and Summers, our independent directors, that no relationships exists, which, in the
opinion of our Board of Directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations,
our Board of Directors reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and relationships as
they may relate to us and our management. There are no family relationships among any of our directors or executive officers.

Classified Board of Directors

In accordance with our amended and restated bylaws, our Board of Directors is divided into three classes with staggered, three-year terms. At each annual meeting of
stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following
election. Our directors are classified as follows:

●

●

●

the Class I director is John Rice, with a term expiring at our 2018 annual meeting of stockholders;

the Class II directors are Frank J. Garofalo and Salvatore Battinelli, with terms expiring at our 2019 annual meeting of stockholders; and

the Class III directors are Dennis Duitch and Kent Summers, with terms expiring at our 2020 annual meeting of stockholders.

Our Board of Directors appointed John Rice as Chairman of the Board on April 19, 2017. Our amended and restated bylaws provide that the authorized number of
directors may be changed by resolution of the Board of Directors. Any additional directorships resulting from an increase in the number of directors will be distributed among
the three classes so that, as nearly as possible, each class will consist of one-third of the directors. The division of our Board of Directors into three classes with staggered three-
year terms may delay or prevent a change of our management or a change in control of our company.

Leadership Structure of the Board

Our directors may be removed with or without cause at any meeting of stockholders by the affirmative vote of the holders of at least two-thirds of our outstanding
voting stock entitled to vote in the election of directors. Our amended and restated bylaws provide our Board of Directors with flexibility in its discretion to combine or separate
the positions of Chairman of the Board and Chief Executive Officer, if we elect to appoint a Chairman of the Board.

On April  19,  2017,  our  Board  of  Directors  appointed  Mr.  Rice  as  Chairman  of  the  Board.  The  Chairman  of  the  Board  presides  at  all  meetings  of  our  Board  of
Directors (but not at its executive sessions) and exercises and performs such other powers and duties as may be assigned to him from time to time by the Board or prescribed by
our amended and restated bylaws. The Chairman of the Board is appointed by our Board of Directors on an annual basis.

Our  Board  of  Directors  has  no  established  policy  on  whether  it  should  be  led  by  a  Chairman  who  is  also  the  Chief  Executive  Officer,  but  periodically  considers
whether  combining,  or  separating,  the  role  of  Chairman  and  Chief  Executive  Officer  is  appropriate. At  this  time,  our  Board  is  committed  to  the  combined  role  given  the
circumstances of our company, including Mr. Rice’s knowledge of our company’s strategy. Our Board believes that having a Chairman who also serves as the Chief Executive
Officer allows timely communication with our board on company strategy and critical business issues, facilitates bringing key strategic and business issues and risks to the
Board’s  attention,  avoids  ambiguity  in  leadership  within  the  Company,  provides  a  unified  leadership  voice  externally  and  clarifies  accountability  for  Company  business
decisions and initiatives. However, our Board of Directors continually evaluates our leadership structure and could, in the future, decide to combine the Chairman and Chief
Executive Officer positions if it believes that doing so would serve the best interests of our Company and our stockholders.

Board Meetings and Committees

During our fiscal year ended December 31, 2017, the Board of Directors held six meetings, and each director attended at least 75% of the aggregate of (i) the total
number of meetings of our Board of Directors held during the period for which he has been a director and (ii) the total number of meetings held by all committees of our Board
of Directors on which he served during the periods that he served.

Although we do not have a formal policy regarding attendance by members of our Board of Directors at annual meetings of stockholders, we encourage, but do not

require, our directors to attend. Each of our then current directors attended our 2017 Annual Meeting of Stockholders, except for one director who was unable to attend.

Our board has established three standing committees-audit, compensation, and nominating and corporate governance-each of which operates under a written charter
that has been approved by our board. Until February 15, 2017, when our common stock became listed on The NASDAQ Capital Market, we were not required to establish or
maintain  an  audit,  nominating  or  compensation  committee.  Each  committee  charter  has  been  posted  on  the  Investors  section  of  our  website  at  www.sigmalabsinc.com.  The
reference to our website address does not constitute incorporation by reference of the information contained at or available through our website, and you should not consider it
to be a part of this Annual Report.

The members of our Compensation Committee are Messrs. Duitch, Battinelli and Summers, and Mr. Battinelli serves as the chairperson of the committee. Our board
has determined that each of Messrs. Duitch, Battinelli and Summers is independent under the applicable NASDAQ rules and regulations and is a “non-employee director” as
defined in Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as  amended  (the  “Exchange Act”).  The  Compensation  Committee  was  established  effective
February 15, 2017 (i.e., when our common stock became listed on The NASDAQ Capital Market).

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee’s responsibilities include:

●

●

●

identifying individuals qualified to become board members;

recommending to our board the persons to be nominated for election as directors and to each of the board’s committees; and

overseeing an annual evaluation of the board.

The members of our Nominating and Corporate Governance Committee are Messrs. Duitch, Battinelli and Summers, and Mr. Duitch serves as the interim chairperson
of  the  committee.  Our  board  has  determined  that  each  of  Messrs.  Duitch,  Battinelli  and  Summers  is  independent  under  the  applicable  NASDAQ  rules  and  regulations.  The
Nominating and Corporate Governance Committee was established effective February 15, 2017 (i.e., when our common stock became listed on The NASDAQ Capital Market).

Code of Ethics and Business Conduct

The  Company  has  a  code  of  ethics  that  applies  to  all  employees,  including  the  Company’s  principal  executive  officer,  principal  financial  officer,  and  principal
accounting officer, as well as to the members of the Board of Directors. The code is available at www.sigmalabsinc.com. The Company intends to disclose any changes in, or
waivers from, this code by posting such information on the same website or by filing a Form 8-K, in each case to the extent such disclosure is required by rules of the SEC or
NASDAQ. The reference to our website address does not constitute incorporation by reference of the information contained at or available through our website, and you should
not consider it to be a part of this Annual Report.

Considerations in Evaluating Director Nominees

Our  Nominating  and  Corporate  Governance  Committee  uses  a  variety  of  methods  for  identifying  and  evaluating  director  nominees.  In  its  evaluation  of  director
candidates,  our  Nominating  and  Corporate  Governance  Committee  will  consider  the  current  size  and  composition  of  our  Board  of  Directors  and  the  needs  of  our  Board  of
Directors and the respective committees of our Board of Directors. Some of the qualifications that our Nominating and Corporate Governance Committee considers include,
without limitation, issues of character, integrity, judgment, diversity of experience, independence, area of expertise, corporate experience, length of service, potential conflicts
of interest and other commitments. Nominees must also have the ability to offer advice and guidance to our Chief Executive Officer based on past experience in positions with a
high  degree  of  responsibility  and  be  leaders  in  the  companies  or  institutions  with  which  they  are  affiliated.  Director  candidates  must  have  sufficient  time  available  in  the
judgment of our Nominating and Corporate Governance Committee to perform all board of director and committee responsibilities. Members of our Board of Directors are
expected to prepare for, attend, and participate in all board of director and applicable committee meetings. Other than the foregoing, there are no stated minimum criteria for
director nominees, although our Nominating and Corporate Governance Committee may also consider such other factors as it may deem, from time to time, are in our and our
stockholders’ best interests.

Although our Board of Directors does not maintain a specific policy with respect to board diversity, our Board of Directors believes that our Board of Directors should
be a diverse body, and our Nominating and Corporate Governance Committee considers a broad range of backgrounds and experiences. In making determinations regarding
nominations  of  directors,  our  Nominating  and  Corporate  Governance  Committee  may  take  into  account  the  benefits  of  diverse  viewpoints.  Our  Nominating  and  Corporate
Governance  Committee  also  will  consider  these  and  other  factors  as  it  oversees  the  annual  board  of  director  and  committee  evaluations. After  completing  its  review  and
evaluation of director candidates, our Nominating and Corporate Governance Committee recommends to our full Board of Directors the director nominees for selection.

Stockholder Recommendations for Nominations to the Board of Directors

Our Nominating and Corporate Governance Committee will consider candidates for director recommended by stockholders so long as such recommending stockholder
was a stockholder of record both at the time of giving notice and at the time of the annual meeting, and such recommendations comply with our amended and restated articles of
incorporation  and  amended  and  restated  bylaws  and  applicable  laws,  rules  and  regulations,  including  those  promulgated  by  the  SEC.  The  Nominating  and  Corporate
Governance  Committee  will  evaluate  such  recommendations  in  accordance  with  its  charter,  our  amended  and  restated  bylaws,  our  policies  and  procedures  for  director
candidates,  as  well  as  the  regular  director  nominee  criteria  described  above.  This  process  is  designed  to  ensure  that  our  Board  of  Directors  includes  members  with  diverse
backgrounds, skills and experience, including appropriate financial and other expertise relevant to our business. Eligible stockholders wishing to recommend a candidate for
nomination  should  contact  the  Secretary  in  writing.  Our  Nominating  and  Corporate  Governance  Committee  has  discretion  to  decide  which  individuals  to  recommend  for
nomination as directors.

Role of Board in Risk Oversight Process

Risk assessment and oversight are an integral part of our governance and management processes. Our Board of Directors encourages management to promote a culture
that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management
meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks we face. Throughout the year,
senior management reviews these risks with the Board of Directors at regular board meetings as part of management presentations that focus on particular business functions,
operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks. Our Board of Directors does not have a standing risk management
committee, but rather administers this oversight function directly through the Board of Directors as a whole, as well as through standing committees of the Board of Directors
that will address risks inherent in their respective areas of oversight. In particular, our Audit Committee is responsible for overseeing our major financial risk exposures and the
steps our management has taken to monitor and control these exposures. The Audit Committee also monitors compliance with legal and regulatory requirements and considers
and approves or disapproves any related-person transactions. Our Nominating and Governance Committee monitors the effectiveness of our corporate governance guidelines
that we may adopt or amend from time to time. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential
to encourage excessive risk-taking by our management.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s executive officers and directors, and persons who own more than 10% of a registered
class of the Company’s equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission (“SEC”). Executive officers,
directors and greater than 10% stockholders are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file.

The Company believes that during its most recent fiscal year ended December 31, 2017, its executive officers, directors and greater than 10% stockholders complied
with the filing requirements under Section 16(a), except that (i) each of Mark Cola, Ronald Fisher and Frank Garofalo filed a Form 3 in connection with his appointment as an
officer and director, an officer, and as a director, respectively, one day after Section 16(a) applied to the Company on February 14, 2017, and (ii) Nannette Toups filed a Form 4
one day late relating to her acquisition of a stock option as compensation in her capacity as an officer.

ITEM 11.  EXECUTIVE COMPENSATION

Processes and Procedures for Compensation Decisions

Our  Compensation  Committee  is  responsible  for  the  executive  compensation  programs  for  our  executive  officers  and  reports  to  our  board  of  directors  on  its
discussions, decisions and other actions. Typically, our Chief Executive Officer makes recommendations to our Compensation Committee and is involved in the determination
of compensation for the respective executive officers that report to him. Our Chief Executive Officer does not determine his own compensation. Our Chief Executive Officer
makes recommendations to our Compensation Committee regarding short- and long-term compensation for all executive officers based on our results, an individual executive
officer’s contribution toward these results and performance toward individual goal achievement. Our Compensation Committee then reviews the recommendations and other
data and makes decisions (or makes recommendations to the Board) as to total compensation for each executive officer as well as each individual compensation component.

The following table sets forth compensation for services rendered in all capacities to the Company: (i) for each person who served as the Company’s Chief Executive
Officer at any time during the past fiscal year, (ii) for each executive officer, other than our Chief Executive Officer, who was employed with the Company on December 31,
2017 and who earned over $100,000 during the fiscal year ended December 31, 2017, and (iii) for any officer who earned over $100,000 during the December 31, 2017 fiscal
year but was no longer employed with the Company on December 31, 2017 (the foregoing executives are herein collectively referred to as the “named executive officers”).

the one-year anniversary of the effective date of Mr. Williams’ employment (the “First Anniversary Date”), provided, however, that vesting as to 50% of the shares accelerated
effective as of the closing of our underwritten public offering (i.e., February 21, 2017), and (iii) a grant, effective as of July 22, 2016, under our 2013 Plan of a non-qualified
stock option to purchase up to 31,500 shares of our common stock. The option has an exercise price equal to the closing price of our common stock on the date of grant, will
vest and become exercisable as follows: 10,500 shares vested and became exercisable on the First Anniversary Date, and the balance of the shares underlying the option will
vest and become exercisable in eight equal installments of 2,625 shares each on a quarterly basis following the First Anniversary Date, and is on the other terms set forth in our
standard form of nonqualified stock option agreement. Mr. Williams agreed to resign from his positions with the Company effective September 28, 2017. Mr. Williams and the
Company entered into a consulting agreement under which Mr. Williams will continue to provide services to the Company on an as needed basis.

Amanda Cola

Effective  as  of  July  21,  2014,  we  entered  into  an  “at  will”  employment  agreement  with  Ms.  Cola,  under  which  Ms.  Cola  was  engaged  to  serve  as  our  Business
Operations Manager, which agreement was amended effective July 21, 2015 to convert Ms. Cola’s position to a full-time position. Under the employment agreement, Ms. Cola
was entitled to receive an annual base salary of $90,000, and the Company issued her as of the effective date of her employment agreement 10,000 shares of common stock
under  the  Company’s  2013  Equity  Incentive  Plan.  Of  these  shares,  2,500  vested  on  the  date  of  grant,  2,500  shares  vested  on  the  first  annual  anniversary  of  Ms.  Cola’s
employment agreement, 2,500 shares vested on the second annual anniversary of Ms. Cola’s employment agreement, and the balance of the shares vested on the third annual
anniversary  of  the  employment  agreement.  On  September  11,  2015,  Ms.  Cola’s  title  was  changed  to  Vice  President  of  Finance  and  Business  Operations  of  the  Company.
Effective as of July 22, 2016, the Company granted Ms. Cola, under the Company’s 2013 Equity Incentive Plan, a non-qualified stock option to purchase up to 15,000 shares of
our common stock. The option has an exercise price equal to the closing price of our common stock on the date of grant, and will vest and become exercisable in four annual
installments  over  four  years.  Effective  as  of April  19,  2017,  Mrs.  Cola’s  salary  was  increased  to  $115,000  per  annum  and  she  was  granted  a  non-qualified  stock  option  to
purchase up to 20,000 shares of our common stock at an exercise price equal to $3.27 per share, which was the closing market price of our common stock on April 19, 2017
(i.e., the date of grant), which is subject to vesting. Effective October 2, 2017, we entered into a transition and separation agreement (the “Separation Agreement”) with Ms.
Cola, pursuant to which we and Ms. Cola agreed that she would voluntarily resign as our Vice President of Finance and Business Operations based on an internal organizational
change. Under the Separation Agreement, we agreed to pay Ms. Cola any and all accrued and unpaid salary, together with all accrued and unpaid vacation pay and other paid
time off, and her then current base monthly salary for a period of six months following the effective date of the Separation Agreement. Under the Separation Agreement, Ms.
Cola’s July 22, 2016 stock option to purchase up to 15,000 shares of the Company’s common stock and her April 19, 2017 stock option to purchase up to 20,000 shares of the
Company’s  common  stock  were amended to provide that the shares underlying such options, once exercisable, will remain exercisable as to such shares for the term of the
options, unless the options are terminated pursuant to a Corporate Transaction (as defined in our 2013 Equity Incentive Plan).

(1) On February 15, 2017, in connection with his appointment to our Board of Directors, the Company granted Mr. Rice 5,231 shares of common stock, under the Company’s
2013 Equity Incentive Plan, with such shares to vest in four equal, successive quarterly installments.
(2) Effective as of February 21, 2017, the Company granted Mr. Cola under his employment agreement a stock option to purchase up to 123,750 shares of our common stock
under the Company’s 2013 Equity Incentive Plan, vesting in equal quarterly installments over an 18-month period.
(3) In August 2015, in conjunction with the hiring of Ronald Fisher, the Company’s Vice President of Business Development, the Company granted to Mr. Fisher a stock option
(the “Option”) to purchase up to 23,750 shares of common stock of the Company, at an exercise price equal to $11.80 per share, which was the closing market price of the
Company’s  common  stock  on August  10,  2015  (i.e.,  the  date  of  grant),  under  the  2013  Plan.  The  Option  vested  and  became  exercisable  as  to  1,375  shares  on  the  first
anniversary  of  the  grant  date  and  as  to  3,375  shares  on  the  second  anniversary  of  the  grant  date,  and  will  vest  and  become  exercisable  as  to  (i)  6,375  shares  on  the  third
anniversary of the grant date, and (ii) 12,625 shares on the fourth anniversary of the grant date, provided, in each case, that Mr. Fisher remains an employee of the Company
through such vesting date. The Option has a ten-year term and is on such other terms set forth in the Company’s standard form of non-qualified stock option agreement. The
Company granted Mr. Fisher under the 2013 Equity Incentive Plan, effective as of August 11, 2016, a stock option to purchase up to 5,000 shares of common stock of the
Company. Such option has an exercise price equal to the closing price of our common stock on the date of grant, and vested and became exercisable as to 300 shares on August
11, 2017, and vests and becomes exercisable as to (i) 700 shares on August 11, 2018, (ii) 1,350 shares on August 11, 2019, and (iii) 2,650 shares on August 11, 2020, provided
Mr. Fisher is in the employ of the Company on August 11, 2017, 2018, 2019 and 2020.
(4) On July 21, 2014 the Company issued to Ms. Cola, as of the effective date of her employment agreement, 10,000 shares of common stock under the Company’s 2013 Equity
Incentive Plan. Of these shares, 2,500 vested on the date of grant, and 2,500 shares vested on each of the three successive anniversary dates of the employment agreement.
Effective as of July 22, 2016, the Company granted Ms. Cola, under the Company’s 2013 Equity Incentive Plan, a non-qualified stock option to purchase up to 15,000 shares of
our common stock. The option has an exercise price equal to the closing price of our common stock on the date of grant, and will vest and become exercisable in four annual
installments over four years On April 19, 2017 Ms. Cola was granted a non-qualified stock option to purchase up to 20,000 shares of our common stock at an exercise price
equal to $3.27 per share, which was the closing market price of our common stock on April 19, 2017 (i.e., the date of grant), which is subject to vesting. Effective October 2,
2017, we entered into a transition and separation agreement (the “Separation Agreement”) with Ms. Cola. Under the Separation Agreement, Ms. Cola’s July 22, 2016 stock
option to purchase up to 15,000 shares of the Company’s common stock and her April 19, 2017 stock option to purchase up to 20,000 shares of the Company’s common stock
were amended to provide that the shares underlying such options, once exercisable, will remain exercisable as to such shares for the term of the options, unless the options are
terminated pursuant to a Corporate Transaction (as defined in our 2013 Equity Incentive Plan).
(5) Effective as of July 22, 2016, Mr. Williams received, under our 2013 Plan, a grant of 15,500 shares of restricted common stock of the Company, which shares vested on the
one-year anniversary of the effective date of Mr. Williams’ employment (the “First Anniversary Date”), provided, however, that vesting as to 50% of the shares accelerated
effective as of the closing of our underwritten public offering (i.e., February 21, 2017), and a grant of a non-qualified five year stock option to purchase up to 31,500 shares of
our common stock. The option has an exercise price equal to the closing price of our common stock on the date of grant, will vest and become exercisable as follows: 10,500
shares  vested  and  became  exercisable  on  the  First Anniversary  Date,  and  the  balance  of  the  shares  underlying  the  option  will  vest  and  become  exercisable  in  eight  equal
installments of 2,625 shares each on a quarterly basis following the First Anniversary Date, and is on the other terms set forth in our standard form of nonqualified stock option
agreement.  Mr.  Williams  agreed  to  resign  from  his  positions  with  the  Company  effective  September  28,  2017.  Mr.  Williams  and  the  Company  entered  into  a  consulting
agreement under which Mr. Williams will continue to provide services to the Company on an as needed basis.

Equity Awards

We offer stock options and stock awards to certain of our employees, including our executive officers, as the long-term incentive component of our compensation
program. We generally grant equity awards to new hires upon their commencing employment with us. Our stock options allow employees to purchase shares of our common
stock at a price per share equal to the fair market value of our common stock on the date of grant and may or may not be intended to qualify as “incentive stock options” for
U.S. federal income tax purposes. We sometimes also offer stock options and stock awards to our consultants in lieu of cash. Our stock options allow consultants to purchase
shares of our common stock at a price per share equal to the fair market value of our common stock on the date of grant and are not intended to qualify as “incentive stock
options” for U.S. federal income tax purposes. Stock options and stock awards granted to our executive officers may be subject to accelerated vesting in certain circumstances.

Retirement Plans

We maintain a qualified 401(k) plan, in which all eligible employees may participate. We have elected to match 100% of each participant’s contribution up to 3% of
salary, and 50% of the next 2% of salary contributed. We may also elect, on an annual basis, to make a discretionary contribution to the plan, but have not done so to date. Our
matches and elective contributions vest to participant accounts as follows: 20% after two years of service, and 20% per year thereafter until the participant reaches 6 years of
service,  at  which  time,  employer  contributions  vest  100%. As  a  tax-qualified  retirement  plan,  contributions  to  the  401(k)  plan  and  earnings  on  those  contributions  are  not
taxable to the employees until distributed from the 401(k) plan.

No Tax Gross-Ups

We  do  not  make  gross-up  payments  to  cover  our  executive  officers’  personal  income  taxes  that  may  pertain  to  any  of  the  compensation  paid  or  provided  by  our

company.

2011 Equity Incentive Plan

On  March  9,  2011,  our  Board  of  Directors  approved  the  Company’s  2011  Equity  Incentive  Plan,  which  was  approved  on  March  31,  2011  by  holders  of  at  least  a
majority of the issued and outstanding shares of common stock of the Company. As of December 31, 2016, an aggregate of 750 shares of our common stock were subject to the
2011 Equity Incentive Plan. The terms and conditions of the 2011 Equity Incentive Plan are substantially similar to the terms and conditions of our 2013 Equity Incentive Plan
(the “2013 Plan”).

2013 Equity Incentive Plan

Purpose

Our Board of Directors adopted the 2013 Plan to (1) encourage selected employees, officers, directors, consultants and advisers to improve our operations and increase
our profitability, (2) encourage selected employees, officers, directors, consultants and advisers to accept or continue employment or association with us, and (3) increase the
interest  of  selected  employees,  officers,  directors,  consultants  and  advisers  in  our  welfare  through  participation  in  the  growth  in  value  of  our  common  stock. All  of  our  12
current employees, directors and consultants are eligible to participate in the 2013 Plan.

Administration

The 2013 Plan is to be administered by the Board or by a committee to which administration of the Plan, or of part of thereof, is delegated by the Board. The 2013 Plan
is  currently  administered  by  our  Compensation  Committee,  which  we  refer  to  below  as  the  “Administrator.”  The  Administrator  is  responsible  for  selecting  the  officers,
employees, directors, consultants and advisers who will receive Options, Stock Appreciation Rights and Stock Awards. Subject to the requirements imposed by the 2013 Plan,
the Administrator is also responsible for determining the terms and conditions of each Option and Stock Appreciation Right award, including the number of shares subject to the
Option, the exercise price, expiration date and vesting period of the Option and whether the option is an Incentive Option or a Non-Qualified Option. Subject to the requirements
imposed by the 2013 Plan, the Administrator is also responsible for determining the terms and conditions of each Stock Award, including the number of shares granted, the
purchase  price  (if  any),  and  the  vesting,  transfer  and  other  restrictions  imposed  on  the  stock.  The Administrator  has  the  power,  authority  and  discretion  to  make  all  other
determinations deemed necessary or advisable for the administration of the 2013 Plan or of any award under the 2013 Plan.

Neither the Board nor any committee of the Board to which administration of the 2013 Plan is delegated will provide advice to participants about whether or not to

accept or exercise their awards. Each participant must make his or her own decision about whether or not to accept or exercise an award.

The 2013 Plan is not subject to the Employee Retirement Income Security Act of 1974 and is not a qualified pension, profit sharing or bonus plan under Section 401(a)

of the Internal Revenue Code

Stock Subject to the 2013 Plan

Subject  to  the  provisions  of  the  2013  Plan  relating  to  adjustments  upon  changes  in  common  stock,  an  aggregate  of  750,000  shares  of  common  stock  are  currently

subject to outstanding awards under the 2013 Plan or future awards under the 2013 Plan.

If awards granted under the 2013 Plan expire or otherwise terminate or are cancelled without being exercised in full, the shares of common stock not acquired pursuant
to such awards will again become available for issuance under the 2013 Plan. If shares of common stock issued pursuant to awards under the 2013 Plan are forfeited to or
repurchased by us, the forfeited or repurchased stock will again become available for issuance under the 2013 Plan.

If shares of common stock subject to an award are not delivered to a participant because such shares are withheld for payment of taxes incurred in connection with the
exercise of an Option, or the issuance of shares under a Stock Award, or the award is exercised through a reduction of shares subject to the award (“net exercised”), then the
number of shares that are not delivered will not again be available for issuance under the 2013 Plan. In addition, if the exercise price of any award is satisfied by the tender of
shares of common stock to us (whether by actual delivery or attestation), the shares tendered will not again be available for issuance under the 2013 Plan.

Eligibility

All directors, employees, consultants and advisors of the Company and its subsidiaries are eligible to receive awards under the 2013 Plan. Incentive Options may only
be granted under the 2013 Plan to a person who is a full-time officer or employee of the Company or a subsidiary. The Administrator will determine from time to time which
directors, employees, consultants and advisers will be granted awards under the 2013 Plan.

Terms of Awards

Written Agreement

Each award under the 2013 Plan will be evidenced by an agreement in a form approved by the Administrator.

Exercise Price; Base Value

The exercise price for a Non-Qualified Option or an Incentive Option may not be less than 100% of the fair market value of the Common Stock on the date of the grant
of the Non-Qualified Option or Incentive Option. With respect to an Option holder who owns stock possessing more than 10% of the total voting power of all classes of our
stock, the exercise price for an Incentive Option may not be less than 110% of the fair market value of the Common Stock on the date of the grant of the Incentive Option. The
base value of a Stock Appreciation Right shall also be no less than 100% of the Common Stock on the date of the grant of the Stock Appreciation Right. The 2013 Plan does not
specify a minimum exercise price for Stock Awards.

Vesting

Each Option, Stock Appreciation Right or Stock Award will become exercisable or non-forfeitable (that is, “vest”) under conditions specified by the Administrator at
the time of grant. Vesting typically is based upon continued service as a director or employee, but may be based upon any performance criteria and other contingencies that are
determined by the Administrator. Shares subject to Stock Awards may be subject to specified restrictions concerning transferability, repurchase by the Company and forfeiture
of the shares issued, together with such other restrictions as may be determined by the Administrator.

Expiration Date

Each Option or Stock Appreciation Right must be exercised by a date specified in the award agreement, which may not be more than ten years after the grant date.
Except  as  otherwise  provided  in  the  relevant  agreement,  an  Option  or  Stock Appreciation  Right  ceases  to  be  exercisable  ninety  days  after  the  termination  of  the  holder’s
employment with us.

Transfers of Options

Unless otherwise determined by the Administrator, Options are not transferable except by will or the laws of descent and distribution.

42

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Purchase Price Payment

Unless otherwise determined by the Administrator, the purchase price of Common Stock acquired under the 2013 Plan is payable by cash or check at the time of an
Option exercise or acquisition of a Stock Award. The Company does not charge participants any fees or commissions in connection with their acquisition of Common Stock
under the 2013 Plan. The Administrator also has discretion to accept the following types of payment from participants:

● A secured or unsecured promissory note, provided that this method of payment is not available to a participant who is a director or an executive officer;

●

Shares of our Common Stock already owned by the Option or Stock Award holder as long as the surrendered shares have a fair market  value that is equal to the acquired
stock and have been owned by the participant for at least six months;

●

The surrender of shares of Common Stock then issuable upon exercise of an Option; and

● A “cashless” option exercise in accordance with applicable regulations of the SEC and the Federal Reserve Board.

Withholding Taxes

At the time of his or her exercise of an Option or Stock Appreciation Right, an employee is responsible for paying all applicable federal and state withholding taxes. A
holder of Stock Awards is responsible for paying all applicable federal and state withholding taxes once the shares covered by the award cease to be forfeitable or at any other
time required by applicable law.

Securities Law Compliance

Shares of Common Stock will not be issued pursuant to the exercise of an Option or the receipt of a Stock Award unless the Administrator determines that the exercise
of the Option or receipt of the Stock Award and the issuance and delivery of such shares will comply with all relevant provisions of law, including, without limitation, the
Securities Act of 1933 (the “Securities Act”), applicable state and foreign securities laws and the requirements of any stock exchange on which our Common Stock is traded.

Effects of Certain Corporate Transactions

Except as otherwise determined by the Administrator, in the event of a “corporate transaction,” all previously unexercised Options and Stock Appreciation Rights will
terminate immediately prior to the consummation of the corporate transaction and all unvested Restricted Stock awards will be forfeited immediately prior to the consummation
of  the  corporate  transaction.  The Administrator,  in  its  discretion,  may  permit  exercise  of  any  Options  or  Stock Appreciation  Rights  prior  to  their  termination,  even  if  those
awards would not otherwise have been exercisable, or provide that outstanding awards will be assumed or an equivalent Option or Stock Appreciation Right substituted by a
successor  corporation.  The Administrator,  in  its  discretion,  may  remove  any  restrictions  as  to  any  Restricted  Stock  awards  or  provide  that  all  outstanding  Restricted  Stock
awards  will  participate  in  the  corporate  transaction  with  an  equivalent  stock  substituted  by  the  successor  corporation  subject  to  the  restrictions.  In  general,  a  “corporate
transaction” means:

●

●

●

●

Our liquidation or dissolution;

Our merger or consolidation with or into another corporation as a result of which we are not the surviving corporation;

A sale of all or substantially all of our assets; or

A purchase or other acquisition of more than 50% of our outstanding stock by one person, or by more than one person acting in concert.

Other Adjustment Provisions

If  the  stock  of  the  Company  is  changed  by  reason  of  a  stock  split,  reverse  stock  split,  stock  dividend,  recapitalization,  combination  or  reclassification,  appropriate
adjustments shall be made by the Administrator, in its discretion, in (1) the number and class of shares of stock subject to the 2013 Plan and each Option and grant of Stock
Awards outstanding under the 2013 Plan, and (2) the purchase price of each outstanding Option and (if applicable) Stock Award. For example, if an Option is for 1,000 shares
for $2.00 per share and there is a 2-for-1 stock split, the Option would be adjusted to be exercisable for 2,000 shares at $1.00 per share.

Amendment or Termination of the Plan

The Board of Directors may at any time amend, discontinue or terminate the 2013 Plan. With specified exceptions, no amendment, suspension or termination of the
Plan  may  adversely  affect  outstanding  Options  or  Stock Appreciation  Rights  or  the  terms  that  are  applicable  to  outstanding  Stock Awards.  No  amendment,  suspension  or
termination of the Plan requires stockholder approval unless such approval is required under applicable law or under the rules of any stock exchange on which our Common
Stock is traded. Unless terminated earlier by the Board of Directors, the 2013 Plan will terminate automatically on March 15, 2023, which is the tenth anniversary of the date of
the 2013 Plan’s adoption by the Board.

As of April 12, 2018, there were 370,126 shares previously issued or subject to outstanding awards under the 2013 Plan and 379,874 shares were available for future

issuance under the 2013 Plan.

Director Compensation

We believe that a combination of cash and equity compensation is appropriate to attract and retain the individuals we desire to serve on our Board of Directors. Our
cash compensation policies are designed to encourage frequent and active interaction between directors and our executives both during and between formal meetings as well as
compensate our directors for their time and effort. Further, we believe it is important to align the long-term interests of our non-employee directors (i.e. directors who are not
employed by us as officers or employees) with those of the Company and its stockholders, and that awarding equity compensation to, and thereby increasing ownership of our
common  stock  by,  our  non-employee  directors  is  an  appropriate  means  to  achieve  this  alignment.  Directors  who  are  also  employees  of  our  company  do  not  receive
compensation for their service on our Board of Directors.

Under our director compensation program, each non-employee director will receive annual compensation of $25,000, which amount will be paid $15,000 in cash, and
$10,000 through the grant of restricted common stock. In addition, the Chairperson of the Audit Committee will receive a $5,000 annual retainer in cash. All cash fees are to be
paid quarterly. In addition, prior to Mr. Rice’s appointment as interim Chief Executive Officer, he received an aggregate of $10,925 in connection with the additional services as
a director that Mr. Rice provided the Company with respect to the Company’s operations. Also, each non-employee director may be reimbursed for his reasonable expenses
incurred in the performance of his duties as a director as our Board of Directors determines from time to time. Our Compensation Committee intends to evaluate our director
compensation program and determine whether any changes should be recommended to the Board.

The following table sets forth certain information concerning the compensation paid to non-employee directors in 2017 for their services as directors of the Company.
The compensation of Mr. Rice, who serves as a director and serves as our interim Chief Executive Officer, is described in the Summary Compensation Table of Executive
Officers. Our non-employee directors do not receive fringe or other benefits.

ITEM 12.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

The following table sets forth certain information regarding beneficial ownership of our common stock as of April 12, 2018 (a) by each person known by us to own
beneficially 5% or more of any class of our common stock,  (b)  by  our  named  executive  officers  and  each  of  our  directors  (and  director  nominees)  and  (c)  by  all  executive
officers and directors of the Company as a group.

The number of shares beneficially owned by each stockholder is determined in accordance with SEC rules. Under these rules, beneficial ownership includes any shares
as to which a person has sole or shared voting power or investment power. Percentage ownership is based on 5,025,118 shares of our common stock outstanding on April 12,
2018.  In  computing  the  number  of  shares  beneficially  owned  by  a  person  and  the  percentage  ownership  of  that  person,  shares  of  common  stock  subject  to  stock  options,
warrants  or  other  rights  held  by  such  person  that  are  currently  convertible  or  exercisable  or  will  become  convertible  or  exercisable  within  60  days  of April  12,  2018  are
considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.

Unless otherwise stated, the address of each 5% or greater beneficial holder is c/o Sigma Labs, Inc., 3900 Paseo del Sol, Santa Fe, New Mexico 87507. We believe,
based  on  information  provided  to  us,  that  each  of  the  stockholders  listed  below  has  sole  voting  and  investment  power  with  respect  to  the  shares  beneficially  owned  by  the
stockholder unless noted otherwise, subject to community property laws where applicable.

majority  of  the  issued  and  outstanding  shares  of  common  stock  of  the  Company. As  of  December  31,  2016,  the  Company  issued  an  aggregate  of  154,250  shares  of  the
Company’s common stock pursuant to the Company’s 2011 Equity Incentive Plan.
(2) On March 15, 2013, the Company’s board of directors approved the Company’s 2013 Equity Incentive Plan. The 2013 Equity Incentive Plan was approved by holders of at
least  a  majority  of  the  issued  and  outstanding  shares  of  common  stock  of  the  Company  on  October  10,  2013.  Pursuant  to  the  2013  Equity  Incentive  Plan,  the  Company  is
authorized  to  grant  “incentive  stock  options”  and  “non-qualified  stock  options”,  grant  or  sell  common  stock  subject  to  restrictions  or  without  restrictions,  and  grant  stock
appreciation  rights  to  employees,  officers,  directors,  consultants  and  advisers  of  the  Company  and  its  subsidiaries.  Incentive  stock  options  granted  under  the  2013  Equity
Incentive Plan are intended to qualify as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code (the “Code”). Non-qualified stock options
granted  under  the  2013  Equity  Incentive  Plan  are  not  intended  to  qualify  as  incentive  stock  options  under  the  Code. As  of  December  31,  2017,  the  Company  issued  an
aggregate of 114,847 shares of the Company’s common stock, as well as options to purchase up to 299,938 shares of the Company’s common stock, some of which are subject

Transactions with Directors and Officers

On August  8,  2017,  we  engaged  Garofalo  & Associates,  LLC,  a  limited  liability  company  owned  and  controlled  by  Mr.  Garofalo,  a  director  of  the  Company,  to

days’ written notice), and (i) 105,000 shares of common stock of the Company upon the closing of an acquisition by the Company of all or substantially all of the equity or
assets (or a controlling interest therein) (the “Closing”) with respect to a specified entity (the value of such shares would have been $238,350 if such shares would have been
issued on August 8, 2017, based on a closing price per share of $2.27 on such date), and (ii) 75,000 shares of common stock of the Company upon the Closing with respect to at
least one of two other specified entities (the value of such shares would have been $170,250 if such shares would have been issued on August 8, 2017, based on a closing price
per share of $2.27 on such date). As of the date of this Annual Report, there are no agreements with respect to the acquisition by the Company of any third party, and there can

other terms and provisions as are contained in the Company’s standard form nonqualified stock option agreement.

Indemnification Agreements

We have entered into indemnification agreements with each of our directors and executive officers. These agreements, among other things, require us to indemnify
each director and executive officer to the fullest extent permitted by Nevada law, including indemnification of expenses such as attorneys’ fees, judgments, fines and settlement
amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in the right of us, arising out of the person’s services
as a director or executive officer.

Policies and Procedures for Related Person Transactions

Our Audit Committee is responsible for reviewing and approving, as appropriate, all transactions with related persons (other than compensation-related matters, which
should be reviewed by our Compensation Committee), in accordance with its Charter and the Nasdaq marketplace rules. In reviewing and approving any such transactions, our
Audit Committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be
obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction.

ITEM 14.

 PRINCIPAL ACCOUNTING FEES AND SERVICES

Our  Audit  Committee  approved  Pritchett,  Siler  &  Hardy,  P.C.  (“PSH”)  to  continue  as  our  independent  registered  public  accounting  firm  to  audit  our  financial
statements for the fiscal year ending December 31, 2017. During our fiscal year ended December 31, 2017, PSH served as our independent registered public accounting firm.
There have been no disagreements on any matter of accounting principles or practices, financial statement disclosures or auditing scope or procedures, which disagreements if
not resolved to their satisfaction would have caused PSH to refer to in their respective opinions. On January 11, 2018, we were informed by PSH that Haynie & Company
(“H&C”)  acquired  certain  assets  of  PSH.  Effective  January  11,  2018,  we  engaged  H&C  to  serve  as  our  independent  registered  public  accounting  firm  for  the  year  ending
December 31, 2018. The engagement of H&C was approved by our Audit Committee.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Stockholders of Sigma Labs, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheet of Sigma Labs, Inc. (the Company) as of December 31, 2017, and the related statements of operations, stockholders’ equity,
and cash flows for the year ended December 31, 2017, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present
fairly, in all material respects, the financial position of the Company as of December 31, 2017, and the results of its operation and its cash flows for the period ended December
31, 2017, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our
audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with
respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange  Commission  and  the
PCAOB.

We  conducted  our  audit  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about
whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an
audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting, but not for the
purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe
that our audit provides a reasonable basis for our opinion.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors
Sigma Labs, Inc.
Santa Fe, New Mexico

We have audited the accompanying balance sheet of Sigma Labs, Inc. as of December 31, 2016 and the related statements of operations, stockholders’ equity and cash flows for
the year then ended. Sigma Labs, Inc.’s management is responsible for these financial statements. Our responsibility is to express an opinion on these financial statements based
on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to
perform,  an  audit  of  its  internal  control  over  financial  reporting.  Our  audit  included  consideration  of  internal  control  over  financial  reporting  as  a  basis  for  designing  audit
procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial
reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Sigma Labs, Inc. as of December 31, 2016 and the
results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

SIGMA LABS, INC.
 NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2017

NOTE 1 – Summary of Significant Accounting Policies

Nature of Business –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 “Company,” “Sigma,” “we,” “us” and “our” refer to Sigma Labs, Inc.

Basis of Presentation – The accompanying financial statements have been prepared by the Company in accordance with Generally Accepted Accounting Principles (“GAAP”)
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 December 31, 2017 and 2016 and for the periods then ended have been made.

Reclassification –  Certain  amounts  in  prior-period  financial  statements  have  been  reclassified  for  comparative  purposes  to  conform  to  presentation  in  the  current-period
financial statements.

Loss Per Share – The computation of loss per share is based on the weighted average number of shares outstanding during the period in accordance with ASC Topic No. 260,
“Earnings Per Share.” Shares underlying the Companies outstanding warrants, options or note conversion features were excluded due to the anti-dilutive effect they would have
on  the  computation. At  December  31,  2017  the  Company  had  1,434,000  warrants,  299,938  stock  options  and  a  $100,000  Convertible  Note  Payable  outstanding.  The  total
number of shares of common stock underlying these instruments is 1,783,938.

Property and Equipment – Property and equipment are stated at cost. Expenditures for major renewals and betterments that extend the useful lives of property and equipment
are  capitalized  upon  being  placed  in  service.  Expenditures  for  maintenance  and  repairs  are  charged  to  expense  as  incurred.  Depreciation  is  computed  using  the  straight-line
method  over  the  estimated  useful  lives  of  the  assets.  The  estimated  life  has  been  determined  to  be  five  years  unless  a  unique  circumstance  exists,  which  is  then  fully
documented as an exception to the policy.

In accordance with its policy, the Company reviews the estimated useful lives of its fixed assets on an ongoing basis. This review indicated that the actual useful life of the
leasehold improvements the Company made to the leased facilities at 3900 Paseo del Sol, Santa Fe, New Mexico in 2014, is less than the fifteen year estimated useful life that
was being used for amortization purposes in the Company’s financial statements. As a result, effective January 1, 2017, the Company changed the estimated useful life of these
improvements to seven years. The effect of this change in estimate was to increase 2017 amortization expense by $12,291 and increase 2017 net loss by $8,509.

Fair  Value  of  Financial  Instruments  -  The  Company  applies ASC  820,  “Fair  Value  Measurements.”  This  guidance  defines  fair  value,  establishes  a  three-level  valuation
hierarchy for disclosures of fair value measurement and enhances disclosure requirements for fair value measures. The three levels are defined as follows:

●

●

Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2  inputs  to  the  valuation  methodology  include  quoted  prices  for  similar  assets  and  liabilities  in  active  markets,  and  inputs that  are  observable  for  the  asset  or
liability, either directly or indirectly, for substantially the full term of the financial instrument.

●

Level 3 inputs to valuation methodology are unobservable and significant to the fair measurement.

The carrying amounts reported in the balance sheets for the cash and cash equivalents, prepaid stock compensation, receivables, accounts payable, and accrued liabilities each
qualify as financial instruments and are a reasonable estimate of fair value because on the short period of time between the origination of such instruments and their expected
realization and their current market rate of interest.

Fair value of financial instruments is as follows:

Level 3

The derivative liability was the result of the original $1 million of Notes, and the 80,000 warrants (post reverse stock split), that were issued in October 2016, both of which
contain anti-dilution provisions in the event the Company engages in specified transactions which occurred in February 2017. As a result, the instruments no longer required
derivative treatment and were written off in February 2017. The following table presents a reconciliation of the derivative liability measured at fair value on a recurring basis

Income Taxes – The Company accounts for income taxes in accordance with ASC Topic No. 740, “Accounting for Income Taxes.”

The Company has no tax positions at December 31, 2017 and 2016 for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of
such deductibility.

The Company recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses. During the years ended December 31,
2017 and 2016, the Company recognized no interest and penalties. All tax years starting with 2014 are open for examination.

Accounts Receivable and Allowance for Doubtful Accounts - Trade accounts receivable are carried at original invoice amount less an estimate made for doubtful accounts.
We determine the allowance for doubtful accounts by identifying potential troubled accounts and by using historical experience and future expectations 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 as income when
received. There was no allowance for doubtful accounts at December 31, 2017 or 2016.

Long-Lived  and  Intangible Assets  –  Long-lived  assets  and  certain  identifiable  definite  life  intangibles  to  be  held  and  used  by  the  Company  are  reviewed  for  impairment
whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company continuously evaluates the recoverability of
its long-lived assets based on estimated future cash flows and the estimated liquidation value of such long-lived assets, and provides for impairment if such undiscounted cash
flows are insufficient to recover the carrying amount of the long-lived assets. If impairment exists, an adjustment is made to write the asset down to its fair value, and a loss is
recorded as the difference between the carrying value and fair value. Fair values are determined based on quoted market values, discounted cash flows or internal and external
appraisals, as applicable. Assets to be disposed of are carried at the lower of carrying value or estimated net realizable value. No impairment was recorded in the years ended
December 31, 2017 or 2016.

Cash Equivalents - The Company considers all highly liquid investments with an original maturity of three months or less at date of purchase to be cash equivalents.

Concentration  of  Credit  Risk  -  The  Company  maintains  its  cash  in  bank  deposit  accounts,  which,  at  times,  may  exceed  federally  insured  limits.  The  Company  has  not
experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents.

Stock Based Compensation – The Company recognizes compensation costs to employees under ASC Topic No. 718, “Compensation – Stock Compensation.” Under ASC
Topic No. 718, companies are required to measure the compensation costs of share-based compensation arrangements based on the grant-date fair value and recognize the costs
in the financial statements over the period during which employees are required to provide services. Share based compensation arrangements may include stock options, grants
of shares of common stock with and without restrictions, performance-based awards, share appreciation rights and employee share purchase plans. As such, compensation cost
is measured on the date of grant at its fair value. Such compensation amounts, if any, are amortized over the respective vesting periods of the option or stock grants.

Equity instruments issued to non-employees are recorded on the basis of the fair value of the instruments, as required by ASC Topic No. 505, “Equity Based Payments to Non-
Employees.”  In  general,  the  measurement  date  is  either  (a)  when  a  performance  commitment,  as  defined,  is  reached  or  (b)  the  earlier  of  the  date  that  (i)  the  non-employee
performance  requirement  is  complete  or  (ii)  the  instruments  are  vested.  The  measured  value  related  to  the  instruments  is  recognized  over  a  period  based  on  the  facts  and
circumstances of each particular grant as defined in the FASB Accounting Standards Codification.

Amortization - Utility patents are amortized over a 17 year period. Patents which are pending are not amortized.

Accounting Estimates - 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.

Revenue Recognition –  The  Company’s  revenue  is  derived  primarily  from  sales  of  our  software  and  related  hardware  suite  and  from  providing  engineering  services  under
contracts. The Company recognizes revenue in accordance with ASC Topic No. 605 based on the following criteria: Persuasive evidence of an arrangement exists, services
have been rendered, the price is fixed or determinable, and collectability is reasonably assured. In general, the Company recognizes service revenue as significant services under
the relevant arrangement have been performed.

F-10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Deferred Stock Offering Costs – Costs related to stock offerings (if any) are deferred and will be offset against the proceeds of the offering in additional paid-in capital. In the
event a stock offering is unsuccessful, the costs relating to the offering will be written-off directly to expense.

Inventory –  Inventories  consisting  of  raw  materials  used  in  the  production  of  customized  parts  totaled  $192,705  and  $187,241,  as  of  December  31,  2017  and  2016,
respectively, and nominal work-in-process components which will be sold to customers. Inventories are valued at the lower of cost or market, using the first-in, first-out (FIFO)
method.

Research and Development – Research and development costs are expensed as they are incurred. Research and development costs for the years ended December 31, 2017 and
2016 were $302,043 and $120,638, respectively.

 Deferred Compensation

In 2014 and 2015, the Company issued to various employees, directors and contractors shares of the Company’s common stock, subject to restrictions, pursuant to the 2013
Equity Incentive Plan (the “2013 Plan”). Such shares were valued at the fair value at the date of issue. The fair value was expensed as compensation over the vesting period and

2017.

During 2017, the Company issued to directors 40,934 shares of the Company’s common stock, subject to restrictions, pursuant to the 2013 Plan valued at $85,408. Such shares

Stock Options

On April 28, 2016, at the Annual Meeting of Stockholders of the Company, the Company’s stockholders approved an amendment to the 2013 Plan to increase the number of
shares of the Company’s common stock reserved for issuance under the 2013 Plan by 319,269 shares of our common stock to a total of 375,000 shares (on a post-Reverse Stock
Split basis). As of December 31, 2016, an aggregate of 750 shares and 199,669 shares of common stock were reserved for issuance under the 2011 Equity Incentive Plan (“The
2011 Plan”) and the 2013 Plan, respectively.

On October 2, 2017, at the Annual Meeting of Stockholders of the Company, the Company’s stockholders approved an amendment to the 2013 Plan to increase the number of
shares of the Company’s common stock reserved for issuance under the 2013 Plan by 375,000 shares of our common stock to a total of 750,000 shares. As of December 31,
2017, an aggregate of 750 shares and 450,062 shares of common stock were reserved for issuance under the 2011 and the 2013 Plan, respectively.

During 2017, the Company granted a total of 213,750 options to 5 employees with vesting periods ranging from 18 months to 4 years beginning May 21, 2017. In 2017, 82,676
options  vested,  and  $510,496  of  compensation  cost  was  recognized  during  the  year. As  of  December  31,  2017,  there  were  options  to  purchase  299,938  shares  issued  and
outstanding under the 2013 Plan. Of this amount, there are vested options exercisable for 85,614 shares of common stock. As of December 31, 2016, the Company had 200,419
shares reserved for future grant under its plans and there were no options exercised during the years ended December 31, 2017.

During 2016, the Company granted a total of 73,688 options to 10 employees with vesting periods ranging from 3 to 4 years beginning March 14, 2017. In 2016, 2,938 options
vested, and $168,411 of compensation cost was recognized during the year. As of December 31, 2016, there were options to purchase 101,188 shares outstanding under the
plans. Of this amount, there were vested options exercisable for 2,938 shares of common stock. As of December 31, 2016, the Company had 200,419 shares reserved for future
grant under its plans and there were no options exercised during the years ended December 31, 2016.

The Company generally grants stock options to employees and directors at exercise prices equal to the fair market value of the Company’s stock on the dates of grant. Stock
options are typically granted throughout the year and generally vest over four years of service and expire ten years from the date of the award, unless otherwise specified. The
Company recognizes compensation expense for the fair value of the stock options over the requisite service period for each stock option award.

Total share-based compensation expense included in the consolidated statements of operations for the years ended December 31, 2017 and 2016 is $719,796, of which $510,496
is related to stock options, and $341,558, of which $200,504 is related to stock options, respectively. There was no capitalized share-based compensation cost as of December
31, 2017 and 2016, and there were no recognized tax benefits during the years ended December 31, 2017 and 2016.

To estimate the value of an award, the Company uses the Black-Scholes option-pricing model. This model requires inputs such as expected life, expected volatility and risk-free
interest  rate.  The  forfeiture  rate  also  impacts  the  amount  of  aggregate  compensation.  These  inputs  are  subjective  and  generally  require  significant  analysis  and  judgment  to
develop. While estimates of expected life, volatility and forfeiture rate are derived primarily from the Company’s historical data, the risk-free rate is based on the yield available
on U.S. Treasury constant maturity rates with similar terms to the expected term of the stock option awards. The fair value of share-based awards was estimated using the Black-
Scholes model with the following weighted-average assumptions for the years ended December 31, 2017 and 2016:

Risk-free interest rate

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted price of our common stock for those awards that
have an exercise price currently below the $2.15 closing price of our Common Stock on December 31, 2017. Three of the 2017 option grants have an exercise price currently
below $2.15.

At December 31, 2017 and 2016, there was $525,606 and $452,551, respectively, of unrecognized share-based compensation expense related to unvested share options with a
weighted average remaining recognition period of 7.33 and 9.29 years, respectively.

Warrants

At December 31, 2017, the Company had outstanding warrants to purchase a total of 1,434,000 shares of common stock, 1,410,000 warrants at an exercise price of $4.00 per
share, which if not exercised, will expire on February 21, 2022, and 24,000 warrants at an exercise price of $2.00 per share which, if not exercised, will expire on October 17,
2019.

NOTE 3 – Notes Payable

Effective  October  17,  2016,  the  Company  entered  into  a  Securities  Purchase Agreement  with  two  accredited  investors  (the  “Investors”)  for  the  private  placement  by  the
Company  of  Secured  Convertible  Notes  in  the  aggregate  principal  amount  of  $1,000,000  (the  “Notes”)  and  warrants  (the  “Warrants”)  to  purchase  up  to  80,000  shares  (the
“Warrant Shares”) of the Company’s common stock (“Common Stock”) (subject to adjustment in certain circumstances), for aggregate gross proceeds, before expenses, to the
Company of $900,000 (the “Financing Transaction”). The Notes were convertible into Shares of Common Stock registered on a Registration Statement for Resale filed with the
Securities and Exchange Commission.

The Notes carried an interest rate of 10% per annum, calculated on the basis of a 360-day year, based on the $1 million Notes Payable effective balance. Such interest was
payable every three months in cash, or, at the holder’s option, in unrestricted shares of Common Stock, if a registration statement is then in effect for such shares of common
stock.

On September 29, 2017, the Company entered into amendments (the “Amendments”) to the October 17, 2016 Secured Convertible Promissory Notes and Warrants to
purchase shares of the Company’s common stock, pursuant to which, among other things set forth in the Amendments, (1) the exercise price of the Warrants was reduced from
$4.13 per share to $2.00 per share, and (2) the conversion price of the Notes was reduced from $4.13 per share to $2.00 per share. Under the Amendments, we paid the Holders
an  aggregate  amount  equal  to  $500,000  (representing  50%  of  the  outstanding  principal  balance  of  the  Notes)  plus  all  accrued  interest  on  the  Notes.  In  consideration  of  the
foregoing, the Holders agreed to, among other things, extend the payment date of the remaining 50% of the outstanding principal balance of the Notes from October 17, 2017 to
the earlier of May 18, 2018 or the closing of our next underwritten public offering of securities in which we raise gross proceeds of at least $3,000,000 (should we elect to
commence and close such an offering of securities).

On December 27 and 28, 2017 the Holders Converted $400,000 of the $500,000 Notes principal and $8,556 of accrued interest on one of the notes into 204,278 shares

of common stock and exercised 56,000 of the warrants @ $2.00 per share for 56,000 additional shares of common stock.

At December 31, 2017 the Company had the remaining $100,000 Convertible Note outstanding and due on the earlier of May 18, 2018 or the closing of our next

underwritten public offering of securities in which we raise gross proceeds of at least $3,000,000 (should we elect to commence and close such an offering of securities).

NOTE 4 – Continuing Operations

The Company has sustained losses and had negative cash flows from operating activities since its inception. The Company has raised significant equity capital and is
developing new products with commercial applications that may increase future revenues. On February 21, 2017, the Company closed an underwritten public offering of equity
securities  resulting  in  net  proceeds  of  approximately  $5.25  million,  after  deducting  underwriting  discounts  and  commissions  and  other  offering  expenses  payable  by  the
Company. The  Company  was  able  to  fund  operations  for  2017  with  these  funds  and  end  the  year  with  a  cash  balance  of  $1,515,674.  On  March  28,  2018,  Sigma  received
$535,000 in full payment of the Morf 3D note and related accrued interest balance. In addition, on April 6, 2018, the Company closed a private placement offering of equity
securities resulting in net proceeds of approximately $840,000, after deducting commissions and other offering expenses payable by the Company. As a result, the Company
currently has sufficient cash and working capital to fund operations through 2018 and is anticipating that significant sales contracts may be closed in the second quarter and
balance of the fiscal 2018 generating material additional cash flow in the near term.

NOTE 5 – Income Taxes

The Company accounts for income taxes in accordance with ASC Topic No. 740. This standard requires the Company to provide a net deferred tax asset or liability equal to the
expected future tax benefit or expense of temporary reporting differences between book and tax accounting methods and any available operating loss or tax credit carryforwards.
Income tax returns open for examination by the Internal Revenue Service consist of tax years ended December 31, 2014 through 2016.

The Company has available at December 31, 2017, unused operating loss carryforwards of approximately $8,617,000, which may be applied against future taxable income and
which  expire  in  various  years  through  2037.  However,  if  certain  substantial  changes  in  the  Company’s  ownership  should  occur,  there  could  be  an  annual  limitation  on  the
amount of net operating loss carryforward which can be utilized. The amount of and ultimate realization of the benefits from the operating loss carryforwards for income tax
purposes is dependent, in part, upon the tax laws in effect, the future earnings of the Company and other future events, the effects of which cannot be determined. Because of the
uncertainty surrounding the realization of the loss carryforwards, the Company has established a valuation allowance equal to the tax effect of the loss carryforwards and other
temporary differences of approximately $2,929,900 and $3,767,996 at December 31, 2017 and 2016, respectively, and, therefore, no deferred tax asset has been recognized for
the loss carryforwards.

Deferred tax assets are comprised of the following:

NOTE 11 - Joint Venture

In July 2015, we entered into a joint venture agreement with Arete Innovative Solutions LLC (“Arete”). The Joint Venture was not consolidated, but rather was accounted for on
the equity method of recording investments. There were no operating activities during the fiscal 2017 and net operations resulted in a loss on the investment of $105 in fiscal
2016. The Company and Arete agreed in 2017 to terminate the Joint Venture and are in the process of paying final costs. The remaining cash asset of the company will be
distributed to the former partners in 2018.

Note 12 - Defined Contribution Plan

In 2014, the Company adopted a qualified 401(K) plan (“the Plan”), in which all employees over the age of 21 may participate. The Company has elected to match 100% of
each participant’s contribution up to 3% of salary, and 50% of the next 2% of salary contributed. The Company may also elect, on an annual basis, to make a discretionary
contribution to the plan. Company matches and discretionary contributions vest to participant accounts as follows: 20% after two years of service, and 20% per year thereafter
until the participant reaches 6 years of service, at which time, employer contributions vest 100%. The costs of matching contributions were $33,725 in 2017 and $35,488 in
2016.

Company as of the date the applicable milestone is satisfied. The maximum shares of stock potentially issuable under this agreement is 23,000 shares.

In February 2018, Sigma granted nine employees ten-year options under the 2013 Equity Incentive Plan to purchase an aggregate of 70,188 shares of common stock, with each
option having an exercise price of $1.56 per share, with each option to vest from and after February 26, 2018 and in accordance with the vesting schedule of each such person’s
existing stock option (i.e., vesting in the same proportions (as closely as possible) and at the same rate), and if any such person did not have an existing stock option, the vesting
schedule of such person’s option is to conform to the vesting schedule of the stock option most recently granted by the Company to a non-executive employee (i.e., vesting in
the same proportions (as closely as possible) and at the same rate), subject in each case to the employee’s continuing employment.

Effective  March  5,  2018,  the Amended  and  Restated Articles  of  Incorporation,  as  amended,  of  Sigma  was  amended  pursuant  to  a  Certificate  of Amendment  filed  with  the
