80% of EAC patients will die within five years of diagnosis, making it the second most lethal cancer in the U.S. The U.S. incidence of
EAC has increased 500% over the past four decades, while the incidences of other common cancers have declined or remained flat. In nearly
all cases, EAC silently progresses until it manifests itself with new symptoms of advanced disease. EAC is nearly always invasive at
diagnosis, and, unlike other common cancers, mortality rates are high even in its earlier stages.</FONT></P>

Esophagus (BE) is an esophageal precancer and complication of GERD characterized by pathologic transformation of surface esophageal cells.
Dysplastic BE is a late esophageal precancer characterized by further premalignant pathologic transformation called dysplasia. All EAC
is believed to arise from BE as the culmination of pathologic changes along the BE-EAC precancer-cancer spectrum&mdash;from nondysplastic
BE (NDBE), to low-grade dysplastic BE (LGD), high-grade dysplastic BE (HGD) and finally EAC. Dysplastic BE can be cured with endoscopic
esophageal ablation which reliably halts progression to EAC.</FONT></P>

subgroup of long-standing or severe GERD patients at-risk for BE and progression to EAC is well defined in clinical practice guidelines,
including the American College of Gastroenterology (ACG) BE Guidelines. Risk factors include age over 50 years, male gender, White race,
obesity, smoking history and a family history of BE-EAC. The ACG BE Guidelines recommend screening for patients with a five-year history
of, or severe, GERD and three or more risk factors. The highest risk symptomatic GERD cohort recommended for screening consists of the
estimated 13 million U.S. men over 50 with one additional risk factor. An estimated 60% of at-risk GERD patients are Medicare beneficiaries.</FONT></P>

for a variety of reasons, less than 10% of at-risk GERD patients who are recommended for screening undergo traditional invasive upper
gastrointestinal endoscopy (EGD). We believe that the profound tragedy of an EAC diagnosis is that likely death could have been prevented
if the at-risk GERD patient had been screened and then undergone surveillance and curative endoscopic esophageal ablation of dysplastic
BE.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Since
mortality rates are high even in early stage EAC, preventing EAC deaths requires detection and intervention at the precancer stage. Most
of the necessary elements for such an early detection program are already well established&mdash;an at-risk population (at-risk GERD
patients), a precancer (BE), and an intervention which can halt progression to EAC (endoscopic esophageal ablation). The only missing
element for such an early detection program is a widespread screening tool that can detect BE prior to EAC.</FONT></P>

2019, an outbreak of a novel strain of a coronavirus occurred, which spread on a global basis to other countries, including the U.S.
On March 11, 2020, the World Health Organization declared a pandemic resulting from the coronavirus, with such pandemic commonly referred
to as the &ldquo;COVID-19 pandemic&rdquo; after the related illness. The COVID-19 pandemic is ongoing, and we continue to monitor the
ongoing impact of the COVID-19 pandemic on the United States national economy, the global economy, and our business.</FONT></P>

COVID-19 pandemic may have an adverse impact on our operations, supply chains, and distribution systems and/or those of our contractors
and our third-party CLIA-certified laboratory partner, and may increase our expenses, including because of preventive and precautionary
measures being taken, restrictions on travel, quarantine polices, and social distancing. Such adverse impacts may include, for example,
the inability of our employees and/or those of our contractors or laboratory partner to perform their work or curtail their services
provided to us. We expect the significance of the COVID-19 pandemic, including the extent of its effect on our consolidated financial
condition and consolidated operational results and cash flows, to be dictated by the success of U.S. and global efforts to mitigate and/or
to contain the spread of the coronavirus, as well as the impact of those efforts.</FONT></P>

spread of the coronavirus also has disrupted the United States&rsquo; healthcare and healthcare regulatory systems which could divert
healthcare resources away from, or materially delay FDA approval with respect to our products. In addition, our clinical trials have
been, and may be further, affected by the COVID-19 pandemic, as site initiation and patient enrollment may be delayed, for example, due
to prioritization of hospital resources toward the virus and/or illness response, as well as travel restrictions imposed by governments,
the inability to access clinical test sites for initiation and monitoring, and the inability of our investigators to perform EGDs
required by our clinical trials. Furthermore, the COVID-19 pandemic may have an adverse impact on the economies and financial markets
of many countries, including the U.S., resulting in an economic downturn that could adversely affect demand for our products and services
and/or our product candidates.</FONT></P>

the large market opportunity for esophageal precancer screening we may face multiple competitors in the future, some of which possess
significantly greater financial and other resources and development capabilities than us. Our EsoGuard test may face competition from
new biomarkers also designed to detect esophageal precancer and conditions along the BE-EAC spectrum.</FONT></P>

Mayo Clinic and Exact Sciences Inc. (Nasdaq: EXAS) have published preliminary data on such biomarkers </FONT><FONT STYLE="font-family: Times New Roman, Times, Serif">and
have publicly expressed a commitment to advancing them to commercialization. Investigators at Johns Hopkins University associated with
a privately held firm called Capsulomics LLC have published limited data on methylation biomarkers for BE. Of note, both groups used
the EsophaCap &ldquo;sponge-on-a-string&rdquo; cell collection device.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Other
manufactures have developed noninvasive esophageal cell collection devices most notably &ldquo;sponge-on-a-string&rdquo; devices which
may compete with EsoCheck. Two such devices, Cytosponge, previously marketed by in the U.S. by Medtronic Inc. (NYSE: MDT), and EsophaCap,
manufactured by Capnostics Inc. and utilized almost exclusively for clinical research, are spherical mesh sponges encapsulated in soluble
gelatin that dissolve in the stomach. The expanded sponge brushes the lining of the esophagus as it is withdrawn and retrieved. Although,
unlike EsoCheck, these devices do not provide anatomic targeting nor protect their sample from dilution and contamination during device
withdrawal, future biomarkers may have sufficient sensitivity to detect BE-EAC despite such dilution and contamination. These or other
manufacturers may also be developing new tools that have not yet been announced that provide noninvasive esophageal cell sampling with
the same or better protection from dilution and contamination as EsoCheck.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Several
well-capitalized companies are developing &ldquo;liquid biopsy&rdquo; tests for early cancer detection based on circulating tumor DNA.
Although none of these tests yet purport to detect early precancer in the bloodstream, technological advances could result in sufficient
sensitivity to do so generally and for conditions along the BE-EAC spectrum. Such advances could put EsoGuard and EsoCheck at a significant
competitive disadvantage in the esophageal precancer screening market as it would be logistically much simpler to send the patient for
a routine blood draw instead of a specialized office procedure like EsoCheck, and patients would generally prefer such a blood draw over
even a noninvasive procedure such as EsoCheck.</FONT></P>

still unproven, technologies with the potential to compete with EsoGuard and EsoCheck in the future, include breath tests and oral tests
which may be capable of identifying the presence of BE. For example, there is early data to suggest that an &ldquo;electric nose&rdquo;
device which measures volatile organic compounds (VOCs) developed by Aeonose, The eNose Company, based in the Netherlands, may be able
to identify patients with BE.</FONT> <FONT STYLE="font-family: Times New Roman, Times, Serif">Preliminary published data from Columbia
University School of Medicine found differences in the oral bacterial microbiome, obtain with a simple saliva sample or oral swab, may
correlate with the presence of BE.</FONT></P>

there can be no assurance that we will pursue the development of any products other than EsoGuard and EsoCheck, if we seek to develop
other products, we may need to compete with a broad range of organizations in the U.S. and other countries that are engaged in the development,
production and commercialization of diagnostic products and services. These competitors include biotechnology, diagnostic and other life

may be unable to compete effectively against our competitors either because their products and services are superior or more cost efficient,
or because they have access to greater resources than us. Our potential competitors may have substantially greater financial, marketing,
sales, distribution, manufacturing, and technological resources. These competitors may also have broader product lines and greater name
recognition than we do. Many of these competitors will have obtained FDA or other regulatory clearances or approvals, and patent protection,
for their products, or are in the process of seeking such clearances, approvals, and protection. Certain of our potential competitors
may commercialize their products in advance of our products. In addition, our competitors may make technical advances that render our
products obsolete. We may be unable to respond to such technical advances, especially given our focus on the EsoGuard and EsoCheck technology.
Although there can be no assurance that we will pursue the development of any products other than EsoGuard and EsoCheck, even if we do
develop new marketable products or services, our current and future competitors may develop products and services that are more commercially
attractive than ours, and they may bring those products and services to market earlier or more effectively than us.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">FDA
defines an LDT as &ldquo;an IVD that is intended for clinical use and designed, manufactured and used within a single laboratory.&rdquo;
Thus, LDTs are considered &ldquo;devices&rdquo;, specifically IVDs, as defined by the FDCA. FDA has long maintained that it has clear
regulatory authority over LDTs and could, therefore, require them to fully comply with the regulatory requirements governing device safety
and effectiveness. FDA, however, has generally not enforced these regulatory requirements for LDTs and has generally not required LDTs
to undergo FDA premarket review of analytical validity and clinical validity, as other IVDs must. For over a decade, FDA has expressed
the opinion that its enforcement discretion was based on the fact that, historically, most LDTs were low-risk, and that it has become
concerned about insufficient regulatory oversight over increasingly high-risk LDTs. FDA has also exercised enforcement discretion of
elements of its &ldquo;single laboratory&rdquo; definition of LDTs which by strict interpretation would require the LDT to have been
&ldquo;designed&rdquo; at the &ldquo;single laboratory&rdquo; and not transferred from another research or commercial laboratory. FDA
has demonstrated its position that it has regulatory authority over all IVDs, by choosing to fully exercise its authority for certain
classes of &ldquo;single laboratory&rdquo; IVDs which would satisfy its definition of an LDT, such as direct-to-consumer tests that do
not involve a health care provider.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">In
July 2010, FDA announced its intent to reconsider its long-standing policy of enforcement discretion with respect to LDTs after identifying
issues with several high-risk LDTs and hosted a public workshop to gather feedback from industry stakeholders. In October 2014, FDA published
two draft guidance documents describing a proposed risk-based framework under which it might regulate LDTs. FDA&rsquo;s draft framework
proposed, among other things, premarket review for higher-risk LDTs, such as those that have the same intended use as FDA-approved or
cleared diagnostics currently on the market. In November 2015, FDA issued a report citing evidence for the need for additional regulation
of LDTs and stated FDA is continuing to work to finalize premarket review requirements for LDTs. However, in November 2016, FDA announced
it would not issue a final guidance for LDTs. In January 2017, FDA issued a Discussion Paper on LDTs, which confirmed it would not finalize
guidance on the regulation of LDTs to allow more time for public discussion and time for the congressional authorizing committees to
develop a legislative solution. In March 2020, the bipartisan Verifying Accurate Leading-edge IVCT Development (VALID) Act of 2020, which
seeks to revamp the regulatory framework of diagnostic tests, including LDTs, was introduced in both chambers of the 116<SUP>th</SUP>
Congress but was never brought to a vote. The VALID Act is expected to be reintroduced in 2021. In August 2020, the Department of Health
and Human Services (HHS) announced that, effective immediately, it was rescinding all guidance, compliance manuals, website statements,
or other informal issuances concerning FDA premarket review of LDTs, and that FDA may not require premarket review of LDTs absent a formal
notice-and-comment rulemaking process.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
long-standing ambiguity of the regulatory status for LDTs makes it impossible for us to predict the future regulatory status of LDTs,
and if or when it may be substantially modified through guidance documents, formal rulemaking, departmental directive, executive order
or pursuant to legislation. For example, the current administration could abruptly rescind the August 2020 HHS directive of the prior
administration, which could restore FDA regulatory authority over LDTs and herald a return to enforcement discretion. Similarly, passage
of the VALID Act could usher a new era of full FDA oversight of LDTs. We cannot predict the potential effect of such shifts in LDT regulation
on EsoGuard or any other LDT we may develop, license or acquire, or the potential impact of such shifts on our business, financial condition
or results of operation.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Our
business could also be materially affected if FDA regains enforcement discretion and modifies it, for example, to require that LDTs be
truly &ldquo;home brewed&rdquo; at a single laboratory, since EsoGuard was designed and developed at the CWRU laboratory and transferred
to our third-party CLIA-certified laboratory partner which performs the test. It could also be materially affected if FDA is granted
broader authority and a mandate to regulate LDTs, through pending legislation such as the VALID Act. If any of these were to occur, we
may be required to change business plans regarding the development and commercialization of EsoGuard and any other LDTs we develop, license
or acquire. They may significantly slow the time it would take us to bring LDTs to market, may materially increase the costs of developing,
and decrease the profitability of providing, EsoGuard and any other LDTs we may develop, license or acquire, and may prevent us from
commercializing certain products or services. We cannot provide any assurance that FDA clearance or approval will not be required in
the future for EsoGuard or any other LDTs we develop, license or acquire, whether as a result of additional guidance or regulations issued
by FDA, new enforcement policies adopted by FDA or new legislation adopted by Congress. It is possible that legislation will be enacted
into law, regulations could be promulgated or guidance could be issued by FDA that may result in increased regulatory burdens for us
to continue to offer diagnostic tests or to develop and introduce new tests. Moreover, if pre-market review is required by FDA or if
we decide to voluntarily pursue FDA&rsquo;s pre-market review for any of our IVDs, there can be no assurance that they will be approved,
or timely approved, nor can there be assurance that labeling claims will be consistent with our current claims or adequate to support
continued adoption of and reimbursement for our tests. If pre-market review is required, our business could be negatively impacted as
a result of commercial delay that may be caused by any new requirements.</FONT></P>

to PMA premarket approval, the most stringent FDA premarket medical device scientific and regulatory review process, which requires sufficient
valid scientific evidence in addition to general and special controls to assure that it is safe and effective for its intended use(s).
Any other IVD we may develop, license, or acquire, would likely also require PMA premarket approval to be marketed with EsoCheck as an
IVD. If we choose, or are required, as a result of changes in LDT regulation, to secure FDA approval of EsoGuard, or any other IVD we
may develop, license or acquire, as an IVD, even if not combined with EsoCheck, we expect we would this require FDA PMA approval.</FONT></P>

process of securing FDA PMA approval is complex and requires substantial time, commitment of resources and expense. The process may take
many years to complete, and approval may never be obtained. It requires us to demonstrate with substantial evidence, gathered in preclinical
and large, complex well-controlled clinical trials, that the planned product is safe and effective for use for as intended. We may not
conduct such a trial or may not successfully enroll or complete any such trial, if required. Any products we may develop may not achieve
the required primary endpoint in the clinical trial and may not receive regulatory approval. We must also demonstrate that the manufacturing
facilities, processes and controls for any products we may develop are adequate.</FONT></P>

can be no assurance that FDA will ever permit us to market EsoGuard, used with EsoCheck, as a combined product or any new product or

successfully obtain or maintain regulatory clearance or approval to sell any products we may develop in the U.S., our business, financial
condition, results of operations and growth prospects could be adversely affected. Furthermore, delays in receipt of clearances or approvals
could materially delay or prevent us from commercializing our products and services or result in substantial additional costs that could
decrease our profitability. Even if we were to successfully obtain and maintain regulatory clearance or approval for a product, any clearance
or approval might contain significant limitations related to use restrictions for specified age groups, warnings, precautions or contraindications,
or may be subject to burdensome post-approval study or risk management requirements.</FONT></P>

We may not be able to enter into replacement arrangements without undue delays or considerable expenditures. If there are delays in testing

to our services. These events could lead to voluntary or legally mandated safety alerts relating to our tests or our laboratory facilities

Insufficient quality controls and any resulting negative outcomes could result in significant costs and litigation, as well as negative

claims, or claims that could potentially change the regulatory status of the product, the agency could take the position that these materials
have misbranded our devices and request that we modify our labeling, advertising, or user training or promotional materials and/or subject
us to regulatory or legal enforcement actions, including the issuance of an Untitled Letter or a Warning Letter, injunction, seizure,
recall, adverse publicity, civil penalties, criminal penalties, or other adverse actions. It is also possible that other federal, state,
or foreign enforcement authorities might take action if they consider our labeling, advertising, promotional, or user training materials
to constitute promotion of an unapproved use, which could result in significant fines, penalties, or other adverse actions under other
statutory authorities, such as laws prohibiting false claims for reimbursement. In that event, we would be subject to extensive fines

statements that could be considered off-label promotion of our products, FDA or another regulatory agency could disagree and conclude
that we have engaged in off-label promotion. In addition, any such off-label use of our products may increase the risk of injury to patients,
and, in turn, the risk of product liability claims, and such claims are expensive to defend and could divert our management&rsquo;s attention
and result in substantial damage awards against us.</FONT></P>

pillar of our growth strategy is to expand EsoGuard commercialization across multiple channels, including direct-to-consumer (DTC) marketing.
Patients with chronic heartburn who respond to DTC advertising of our products or to consumer-oriented educational material we provide,
or who otherwise become aware of the availability of a simple noninvasive test to screen for esophageal precancer may seek EsoGuard testing.
We intend to facilitate access to EsoGuard testing for such patients by contracting with one or more third-party telemedicine companies
who will provide physicians to evaluate such a patient via video communications, determine whether EsoGuard testing is clinically indicated
based on the patient&rsquo;s history and condition, and order an EsoGuard test by referring the patient to one of our patient service
centers where the patient would undergo EsoCheck specimen collection for EsoGuard testing by our third-party CLIA-certified laboratory
partner. The EsoGuard test result would then be sent directly to the prescribing telemedicine physician who, based on the test result,
would refer the patient to a gastroenterologist for further care.</FONT></P>

logistics required to manage the patient&rsquo;s journey through such a DTC/telemedicine program, in a manner which is compliant with
all applicable regulations, are complex and require very careful coordination between us and our third-party telemedicine and laboratory
partners broadly operating within our quality management system. Our activities and the activities of our third-party partners on our
behalf within this DTC/telemedicine program are subject to numerous federal and state regulations. The telemedicine provider itself may
be subject to additional state regulations relating to the corporate practice of medicine, test orders, patient consents, medical necessity
requirements and billing regulations. Telemedicine, and its specific use in conjunction with DTC, faces particularly intense scrutiny
from regulators due to numerous cases of companies failing to operate in this space with a properly functioning regulatory and compliance
infrastructure. For example, in recent years, the federal government has conducted several major investigations into the use of telemedicine
to generate orders or prescriptions for laboratory tests, pharmaceuticals, durable medical equipment and other ancillary items and services
that are billed to Medicare and other federal health care program (FHCPs). In such cases, the supplier that received the order or prescription
and billed for the ancillary item or service would compensate the telemedicine provider (or management company) for the patient consultation
because the actual telehealth service may not be a covered service or meet the coverage requirements under the Medicare or other FHCPs
(due to lack of provider-patient relationship or audio-only modality). The Department of Justice has prosecuted providers on the legal
theory that this is akin to a kickback or bribe in the form of remuneration paid to the telemedicine provider or management company for
the order or prescription itself, whether the ancillary item or service was medically necessary.</FONT></P>

2018, Congress passed Eliminating Kickbacks in Recovery Act, or &ldquo;<I>EKRA</I>,&rdquo; as part of the Substance Use-Disorder Prevention
that Promotes Opioid Recovery and Treatment for Patients and Communities Act. Similar to the Anti-Kickback Statute, EKRA imposes criminal
penalties for knowing or willful payment or offer, or solicitation or receipt, of any remuneration, whether directly or indirectly, overtly
or covertly, in cash or in kind, in exchange for the referral or inducement of laboratory testing (among other healthcare services) unless
a specific exception applies. However, unlike the Anti-Kickback Statute, EKRA is not limited to services covered by federal or state
healthcare programs but applies more broadly to services covered by &ldquo;healthcare benefit programs,&rdquo; including commercial insurers.
As currently drafted, EKRA potentially expands the universe of arrangements that could be subject to government enforcement under federal
fraud and abuse laws. In addition, while the Anti-Kickback Statute includes certain exceptions that are widely relied upon in the healthcare
industry, not all of those same exceptions apply under EKRA. Because EKRA is a relatively new law, there is no agency guidance or court
precedent to indicate how and to what extent it will be applied and enforced. We cannot assure you that our relationships with healthcare

third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Third-party

be eligible for coverage by third-party payors or, if eligible for coverage, what the reimbursement rates will be. Reimbursement of esophageal
precancer and cancer screening by a third-party payor may depend on a number of factors, including a payor&rsquo;s determination that
tests using our technologies are sufficiently sensitive and specific for esophageal cancer and precancer; not experimental or investigational;
approved or recommended by the major guidelines organizations; reliable, safe and effective; medically necessary; appropriate for the

addition to the risk of adverse reimbursement decisions, we also may experience material delays in obtaining such reimbursement decisions
and payment for our EsoGuard test and EsoCheck device that are beyond our control. Further, there can be no assurance that CMS and other
third-party payors who initially decide to cover our products will continue to do so. Coverage determinations and reimbursement rates
are subject to change, including as a result of reimbursement rate adjustments under the Protecting Access to Medicare Act of 2014, or
&ldquo;<I>PAMA</I>,&rdquo; as described below, and we cannot guarantee that even if we initially achieve coverage and adequate reimbursement
rates, they will continue to be applicable to our products in the future. Furthermore, it is possible that Medicare or other federal
payors that provide reimbursement for our tests may suspend, revoke or discontinue coverage at any time, may require co-payments from
patients, or may reduce the reimbursement rates payable to us.</FONT></P>

laws that mandate coverage for certain esophageal precancer and cancer screening tests, we may sue to enforce coverage obligations or
pursue similar tactics. Such litigation and tactics may be costly, may divert management attention from other responsibilities, may cause
payors, including those not directly involved in any litigation, to resist contracting with us, and may ultimately prove unsuccessful.</FONT></P>

where a third-party payor agrees to cover EsoGuard and EsoCheck at an adequate reimbursement rate, other factors may have a significant
impact on the actual reimbursement we receive for an EsoGuard test or EsoCheck device from that payor. For example, if we do not have
a contract with a given payor, we may be deemed an &ldquo;out-of-network&rdquo; provider by that payor, which could result in the payor
allocating a portion of the cost of the EsoGuard test or EsoCheck device to the patient, notwithstanding any applicable coverage mandate.
We may be unsuccessful in our efforts to enter into, or maintain, a network contract with a given payor, and we expect that our network
status with a given payor may change from time to time for a variety of reasons, many of which may be outside our control. To the extent
EsoGuard or EsoCheck is out of network for a given payor, physicians may be less likely to prescribe EsoGuard and EsoCheck for their
patients and their patients may be less likely to comply with those prescriptions that are written. Also, some payors may require that
they give prior authorization for an EsoGuard test or EsoCheck device before they are willing to pay for it or review claims post-service
to ensure the service was medically appropriate for specific patients. Prior authorization and other medical management practices may
require that we, patients or physicians provide the payor with extensive medical records and other information. Prior authorization and
other medical management practices impose a significant additional cost on us, may be difficult to comply with given our position as
a laboratory that generally does not have direct access to patient medical records, may make physicians less likely to prescribe EsoGuard
and EsoCheck for their patients, and may make patients less likely to comply with physician orders for EsoGuard and EsoCheck, all or
any of which may have an adverse effect on our revenues. Payment rates also may vary according to the use of the product and the clinical
setting in which it is used, may be based on payments allowed for lower cost products that are already reimbursed and may be incorporated
into existing payments for other services. Net prices for products may be reduced by mandatory discounts or rebates required by government
healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of products from countries
where they may be sold at lower prices than in the U.S.</FONT></P>

regulations that govern pricing and reimbursement for new products vary widely from country to country. Some countries require approval
of the sale price of a product before it can be marketed. In many countries, the pricing review period begins after marketing clearance
or approval is granted. In some foreign markets, pricing remains subject to continuing governmental control even after initial approval
is granted. As a result, we might obtain regulatory clearance or approval for a product in a particular country, but then be subject
to price regulations that delay our commercial launch of the product and negatively impact the revenue we are able to generate from the
sale of the product in that country. In addition, to obtain reimbursement or pricing approval in some countries, we may be required to
conduct a clinical trial that compares the cost-effectiveness of our product to other available therapies. Adverse pricing limitations
may hinder our ability to recoup our investment in the EsoGuard and EsoCheck products and any other products, tests or services we develop,

complaints or lawsuits, including to the extent EsoGuard tests are not fully covered by insurers and patients become responsible for

the U.S., there have been, and we expect there will continue to be, ongoing legislative and regulatory changes to the healthcare system
which could affect our future revenue and profitability. Federal and state lawmakers regularly propose and, at times, enact legislation
that could result in significant changes to the healthcare system, some of which are intended to contain or reduce the costs of medical
products and services. For example, one of the most significant healthcare reform measures in decades, the Patient Protection and Affordable
Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or &ldquo;<I>PPACA</I>,&rdquo; was enacted in
2010. The PPACA contains a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement changes
and fraud and abuse measures, all of which will impact existing government healthcare programs. The PPACA, among other things, also could
result in the imposition of injunctions.</FONT></P>

the U.S. Supreme Court has repeatedly upheld the constitutionality of most elements of the PPACA, other legal challenges are still pending
final adjudication in several jurisdictions. Although efforts in Congress to repeal the PPACA have repeatedly fallen short, there are
a number of ongoing legislative initiatives to modify it. At this time, it remains unclear whether there will be any changes made to
the PPACA. We cannot assure you that the PPACA, as currently enacted or as amended in the future, will not adversely affect our business
and financial results and we cannot predict how future federal or state legislative or administrative changes relating to healthcare
reform will affect our business.</FONT></P>

addition, other legislative changes have been proposed and adopted since the PPACA was enacted. There likely will continue to be legislative

for all products and services, including ours, remains highly susceptible to threats of automatic reductions triggered by budgetary shortfalls.
Such payments are subject to recovery of purported overpayment for several years. We cannot predict the initiatives that may be adopted
in the future or their full impact. We cannot predict whether any additional legislative changes will affect our business.</FONT></P>

changes in regulatory requirements and guidance may occur, both in the United States and in foreign countries, and we may need to amend
clinical study protocols to reflect these changes. Amendments may require us to resubmit our clinical study protocols to an IRB for reexamination,
which may impact the costs, timing or successful completion of a clinical study. In light of widely publicized events concerning the
safety risk of certain drug and medical device products, regulatory authorities, members of Congress, the Governmental Accounting Office,
medical professionals and the general public have all raised concerns about potential safety issues. These events have resulted in the
recall and withdrawal of medical device products, revisions to product labeling that further limit use of products and establishment
of risk management programs that may, for instance, restrict distribution of certain products or require safety surveillance or patient
education. The increased attention to safety issues may result in a more cautious approach by FDA or other regulatory authorities to
clinical studies and the medical device approval process. Adverse event data from clinical studies may receive greater scrutiny with
respect to product safety, which may make FDA or other regulatory authorities more likely to terminate or suspend clinical studies before
completion, or require longer or additional clinical studies that may result in substantial additional expense and a delay or failure
in obtaining approval or approval for a more limited indication than originally sought.</FONT></P>

the serious public health risks of high profile adverse safety events with certain products, FDA or other regulatory authorities may
require, as a condition of approval, costly risk evaluation and mitigation strategies, which may include safety surveillance, restricted

preapproval of promotional materials and restrictions on direct-to-consumer advertising.</FONT></P>

reform laws, including the PPACA and PAMA, are significantly affecting the U.S. healthcare and medical services industry. Recently passed
legislation and possible future legal and regulatory changes, including potential repeal or modification of the PPACA, or approval of
health plans that allow lower levels of coverage for preventive services, could substantially change the structure and finances of the
health insurance system and the methodology for reimbursing medical services, drugs and devices, including our current and future products
and services. Healthcare reforms, which may intend to reduce healthcare costs, may have the effect of discouraging third-party payors
from covering certain kinds of medical products and services, particularly newly developed technologies, such as our EsoGuard test or
EsoCheck device, or any other products or services we develop. We cannot predict whether future healthcare reform initiatives will be
implemented at the federal or state level or the effect any such future legislation or regulation will have on us. The taxes imposed
by new legislation, cost reduction measures and the expansion in the government&rsquo;s role in the U.S. healthcare industry may result
in decreased profits to us, which may adversely affect our business, financial condition and results of operations.</FONT></P>

Medicare currently covers a significant portion of the patients in the current targeted screening population for EsoGuard, any reduction

under PAMA that adequate CMS reimbursement rates will initially be assigned or will continue to be assigned to our tests. Further, it
is possible that Medicare or other federal payors that provide reimbursement for our tests in the future may later suspend, revoke or
discontinue coverage at any time, may require co-payments from patients, or may reduce the reimbursement rates payable to us. Any such
action could have a negative impact on our revenues.</FONT></P>

recently received CE Mark certification for EsoCheck under MDD and completed CE Mark self-certification for EsoGuard, which qualifies
as a General IVD, under IVDD, indicating that both may be marketed in CE Mark European countries, namely the European Economic Area (the
European Union, Norway, Iceland, and Lichtenstein), Switzerland, and, until July 1, 2023, the United Kingdom. MDD, which refers to <I>Medical
Device Directive 93/42/EEC</I>, has provided the essential requirements and conformity assessment procedure that medical devices must
undergo to be affixed with a CE Mark and sold in CE Mark European countries for nearly three decades but is now obsolete and has been
replaced by MDR, which refers to <I>Regulation (EU) 2017/745</I> and incorporates several new concepts and registrations, stricter oversight
of manufacturers by notified bodies, universal device identification (UDI) marking, and increased post-market surveillance requirements.
Similarly, IVDD, which refers to <I>In-Vitro Diagnostic Medical Devices Directive (98/79/EC)</I>, has provided the essential requirements
and conformity assessment procedure that <I>in-vitro</I> diagnostic medical devices must undergo to be affixed with a CE Mark and sold
in CE Mark European countries for over twenty years but will become obsolete and replaced in 2022 with IVDR, which refers to <I>Regulation
(EU) 2017/746</I>, and has an expanded scope, risk-based classification, more rigorous clinical evidence and surveillance requirements,
and more stringent documentation. Both MDR and IVDR have sunset provisions for medical device and IVD certifications under MDD and IVD,
respectively. Both EsoGuard and EsoCheck will require recertification under their stricter regulations in the coming years. Failure to
secure these recertifications under MDR and IVDR will halt our ability to commercialize our products in the CE Mark European countries.
In addition, the United Kingdom, which is a major target market for us, has left the European Union (&ldquo;Brexit&rdquo;) and will transition
from CE Mark certification to its own UKCA certification mark. If we fail to secure UKCA mark certification for our products before CE
Mark certification expires in the UK, we will no longer be able to commercialize our products there, which may adversely impact our business.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">FDA
has the authority to require the recall of commercialized medical device products in the event of material deficiencies or defects in
design or manufacture. In the case of FDA, the authority to require a recall must be based on an FDA finding that there is a reasonable
probability that the device would cause serious injury or death. Manufacturers may, under their own initiative, recall a product if any
material deficiency in a device is found. A government-mandated or voluntary recall by us or one of our distributors could occur as a
result of component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. Recalls of any of our
products would divert managerial and financial resources and have an adverse effect on our financial condition and results of operations.
FDA requires that certain classifications of recalls be reported to FDA within ten working days after the recall is initiated. Companies
are required to maintain certain records of recalls, even if they are not reportable to FDA. We may initiate voluntary recalls involving
our products in the future that we determine do not require notification of FDA. If FDA disagrees with our determinations, they could
require us to report those actions as recalls. A future recall announcement could harm our reputation with customers and negatively affect
its sales. In addition, FDA could take enforcement action for failing to report the recalls when they were conducted. No recalls of our
medical products have been reported to FDA.</FONT></P>

healthcare data transfers from other countries relating to citizens of those countries, we must comply with the laws of those countries.
The federal privacy regulations restrict our ability to use or disclose patient identifiable data, without patient authorization, for
purposes other than payment, treatment, healthcare operations and certain other specified disclosures such as public health and governmental
oversight of the healthcare industry.</FONT></P>

are exposed to the risk of fraud, misconduct, or other illegal activity by our employees, independent contractors, consultants, commercial
partners, and vendors. Misconduct by these parties could include intentional, reckless and negligent conduct that fails to: comply with
the rules and regulations of the CMS, FDA, and other comparable foreign regulatory authorities; provide true, complete and accurate information
to such regulatory authorities; comply with manufacturing and clinical laboratory standards; comply with healthcare fraud and abuse laws
in the United States and similar foreign fraudulent misconduct laws; or report financial information or data accurately or to disclose
unauthorized activities to us. In particular, research, sales, marketing, education, and other business arrangements in the healthcare
industry are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing, and other abusive practices, as well as off-label
product promotion. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, educating, marketing and
promotion, sales and commission, certain customer incentive programs, and other business arrangements generally. Activities subject to
these laws also involve the improper use of information obtained in the course of participant recruitment for clinical studies, which
could result in regulatory sanctions and cause serious harm to our reputation. We have adopted a code of business conduct and ethics,
but it is not always possible to identify and deter misconduct by employees and third parties, and the precautions we take to detect
and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental
investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws. If any such actions are instituted
against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on
our business, including the imposition of significant fines or other sanctions. Even if it is later determined after an action is instituted
against us that we were not in violation of these laws, we may be faced with negative publicity, incur significant expenses defending
our actions, and have to divert significant management resources from other matters.</FONT></P>

success depends significantly on our ability to protect the patents, trademarks, trade secrets, copyrights and the other intellectual
property rights for the technology used, or expected to be used, in our products. We rely primarily on patent protection and trade secrets,
including the patents to the EsoGuard and EsoCheck technologies licensed by us from CWRU, as well as a combination of copyright and trademark
laws and nondisclosure and confidentiality agreements to protect the technology and other intellectual property on which we rely. However,
these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or maintain any competitive
advantage. In addition, although we have the right to direct CWRU to seek patent protection for the EsoGuard and EsoCheck technology
in additional countries, we have limited control over the prosecution of any such application and have limited control over CWRU&rsquo;s
other intellectual property practices as they relate to the EsoGuard and EsoCheck technologies. Despite our intellectual property rights
practices, it may be possible for a third party to copy or otherwise obtain and use the technology on which we rely without authorization,
develop similar technology independently or design around our patents. Furthermore, protecting intellectual property rights is costly
and time consuming. We are responsible for the costs of CWRU in preparing, filing and prosecuting any patents related to the EsoGuard
technology (subject to a provision for cost sharing in the event CWRU grants additional licenses to the technology, none of which would
be permitted to overlap with our field of use).</FONT></P>

relied on by us may expire or may be challenged, invalidated, or circumvented, which could limit our ability to stop competitors from
marketing related technologies. If any of the patents fails to protect the technology used by us, it would make it easier for our competitors
to offer similar products. In addition, there is no assurance that competitors will not be able to design around the patents. Upon expiration
of the patents, we may lose some of our rights to exclude others from making, using, selling, or importing products using the technology
based on the expired patents. We cannot be assured that any pending or future patent applications for the technology on which we rely
will result in the issuance of a patent to us. The U.S. Patent and Trademark Office, or the &ldquo;<I>PTO</I>,&rdquo; may deny or require
significant narrowing of claims in the patent applications, and patents issued as a result of the patent applications, if any, may not
provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incur substantial
costs in proceedings before the PTO.</FONT></P>

also rely on unpatented proprietary technology. We cannot assure you that we can meaningfully protect all our rights in our unpatented
proprietary technology or that others will not independently develop substantially equivalent proprietary products or processes or otherwise
gain access to our unpatented proprietary technology. We seek to protect our know-how and other unpatented proprietary technology with
confidentiality agreements and/or intellectual property assignment agreements with our team members, independent distributors and consultants.
However, such agreements may not be enforceable or may not provide meaningful protection for our proprietary information in the event
of unauthorized use or disclosure or other breaches of the agreements or in the event that our competitors discover or independently
develop similar or identical designs or other proprietary information. Our trade secrets may be vulnerable to disclosure or misappropriation
by employees, contractors, and other persons.</FONT></P>

that are important to our business. Searches for existing intellectual property rights may not reveal important intellectual property
and our competitors may also have filed for patent protection, information which is not publicly available, just as claimed trademark

on those IT systems to receive and process EsoGuard test orders, securely store patient health records and deliver the results of our
EsoGuard tests. IT systems are vulnerable to damage from a variety of sources, including telecommunications or network failures, malicious

in legal claims or proceedings, liability under laws that protect the privacy of personal information, damage to our reputation, and
delays in the commercialization of our products. In addition, we could incur additional cost, expense and the diversion of time and resources

currently owns approximately 73.7% of our outstanding common stock. Following PAVmed&rsquo;s expected conversion, prior to this offering,

PAVmed will hold approximately [&#9679;]% of the combined voting power of our outstanding common stock (or approximately [&#9679;]% if
the underwriters exercise in full their option) and will remain our controlling stockholder. Accordingly, PAVmed generally will control
the outcome of any transaction that requires stockholder approval. This means that, for the foreseeable future, investors in this offering
will not have a meaningful voice in our corporate affairs and that the control of our company will be concentrated with PAVmed. For as
long as PAVmed continues to control more than 50% of our common stock, PAVmed will be able to direct the election of all the members
of our board of directors. In addition, until such time as PAVmed beneficially owns shares of our common stock representing less than
a majority of the votes entitled to be cast by the holders of outstanding voting stock, PAVmed will have the ability to take stockholder
action without the vote of any other stockholder and without having to call a stockholder meeting, and investors in this offering will
not be able to affect the outcome of any stockholder vote during this period. Similarly, PAVmed will have the ability to prevent the
approval of any action submitted to the stockholders. If PAVmed does not provide any requisite consent allowing us to take any such action
when requested, we will not be able to engage in the related activities and, as a result, our business and our operating results may
be harmed.</FONT></P>

voting control and its additional rights described above may discourage transactions involving a change of control of us, including transactions
in which holders of our common stock might otherwise receive a premium for their shares over the then-current market price. PAVmed is
not prohibited from selling a controlling interest in us to a third party and may do so without the approval of the other stockholders
and without providing for a purchase of our other shares of common stock. Accordingly, shares of common stock held by our other stockholders
may be worth less than they would be if PAVmed did not maintain voting control over us or have the additional rights described above.</FONT></P>

we do not anticipate changing our decision, for so long as a majority of our outstanding common stock is held by PAVmed (or by any other
stockholder or group of stockholders), we could choose to rely on this exemption in the future to avoid complying with certain of the
Nasdaq corporate governance rules, including the rules that require us to have a board comprised of at least 50% independent directors,
to have board nominations either selected, or recommended for the board&rsquo;s selection, by either a nominating committee comprised
solely of independent directors or by a majority of the independent directors and to have officer compensation determined, or recommended

a result of the foregoing, a potential business opportunity may be presented by certain members of our management team to another entity

those opportunities to another PAVmed Party prior to presenting them to us. Accordingly, any conflicts of interest among us and our officers,
directors, stockholders or their affiliates, including PAVmed and certain of our officers and directors, relating to business opportunities
may not be resolved in our favor, and in cases where the business opportunity is a PAVmed Opportunity and it is presented to another

PAVmed, our majority shareholder, operates in the medical device industry. As a result, PAVmed may produce devices that compete directly
or indirectly with our products. While PAVmed will not pursue any opportunity related to commercializing the EsoGuard diagnostic test
or the EsoCheck cell collection device or developing and commercializing other products that use or enhance the same underlying technology,
there can be no assurance that PAVmed will not engage in increased competition with us in the future. PAVmed could assert control over
us in a manner which could impede our growth or our ability to enter new markets or otherwise adversely affect our business. PAVmed could
utilize its control over us to cause us to take or refrain from taking certain actions, including with respect to entering into relationships
with sales, marketing, distribution, technology and other partners, enforcing our intellectual property rights, and pursuing corporate
opportunities or product development initiatives, which could adversely affect our competitive position, including our competitive position
relative to that of PAVmed in markets where we may compete with them in the future. If any of these scenarios were to materialize, our
market share could be reduced, which could have an adverse impact on our results of operations.</FONT></P>

indicative of our future results of operations, financial position, cash flows or costs and expenses. We have not made adjustments to
reflect the changes that will occur in our cost structure, funding and operations as a result of our separation from PAVmed, such as
increased costs associated with being a publicly traded, stand-alone company. We also have not made adjustments to reflect the many significant
changes that will occur in our cost structure, funding and operations once our Board of Directors determines that we should be managed

As a result of this volatility, investors may not be able to sell their common stock at or above the initial public offering price. The
market price for our common stock may be influenced by many broad market and industry factors. These broad market and industry factors
may seriously harm the market price of our common stock, regardless of our operating performance. In addition, the market price for our
common stock may be subject to price movements that may not comport with macro, industry or company-specific fundamentals, including,
without limitation, the sentiment of retail investors (including as may be expressed on financial trading and other social media sites
and online forums), the direct access by retail investors to broadly available trading platforms, the amount and status of short interest
in our securities, access to margin debt, trading in options and other derivatives on our common stock and any related hedging and other
trading factors. In the past, following periods of volatility in the market, securities class-action litigation has often been instituted
against companies. Such litigation, if instituted against us, could result in substantial costs and diversion of management&rsquo;s attention
and resources, which could materially and adversely affect our business, financial condition, results of operations and growth prospects.</FONT></P>

applicable to public companies will require considerable time and attention of management. For example, the Sarbanes-Oxley Act and the
rules of the SEC and national securities exchanges have imposed various requirements on public companies, including requiring establishment
and maintenance of effective disclosure and financial controls. Our management and other personnel will need to devote a substantial
amount of time to these compliance initiatives. These rules and regulations will continue to increase our legal and financial compliance
costs and will make some activities more time-consuming and costly. For example, we expect these rules and regulations to 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 on coverage or incur substantial costs to maintain the same or similar coverage. The impact of these events could also make it

are an &ldquo;emerging growth company,&rdquo; as defined in the Jumpstart Our Business Startups Act, or the JOBS Act, which was enacted
in April 2012. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting
requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply
with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, reduced disclosure
obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding
a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.
We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier. We will
remain an emerging growth company until the earlier of (1) the last day of the fiscal year following the fifth anniversary of the completion
of this offering, (2) the last day of the fiscal year in which we have total annual gross revenue of at least $1.07 billion, (3) the
date on which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates
exceeds $700.0 million as of the prior June 30<SUP>th</SUP>, and (4) the date on which we have issued more than $1.0 billion in non-convertible
debt securities during the prior three-year period. We cannot predict if investors will find our common stock less attractive because
we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading
market for our common stock and our stock price may suffer or be more volatile.</FONT></P>

of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition
period under the JOBS Act.</FONT></P>

exclusive forum provision may limit a stockholder&rsquo;s ability to bring a claim in a judicial forum that it finds favorable for disputes

By requiring a stockholder to bring such a claim in the Court of Chancery (or the federal district court for the District of Delaware,
in the case of an action under the Securities Act or the rules and regulations thereunder), the exclusive forum provision also may increase
the costs to a stockholder of bringing such a claim. Alternatively, if a court were to find the exclusive forum provision contained in

associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition.</FONT></P>

U.S. states and then nationwide. We also soon expect to launch an EsoGuard Telemedicine Program, serving Phoenix, in partnership with
an independent third-party telemedicine provider, to accommodate EsoGuard self-referrals from direct-to-consumer marketing. We intend
to use proceeds from this offering to expand this program alongside the Lucid Test Centers and deploy direct-to-consumer marketing to
drive self-referrals to the program.</FONT></P>

second pillar of our growth strategy is to expand the clinical evidence of our products&rsquo; efficacy to support our ongoing regulatory,
reimbursement and commercial efforts, as well as recommendation of our products in clinical practice guidelines. We intend to use proceeds
from this offering to complete our ongoing ESOGUARD-BE-1 and BE-2 clinical trials, to extend ESOGUARD-BE-1 to support a dysplasia indication
pursuant our Breakthrough Device discussions with FDA, and to launch additional clinical studies to support our commercial and reimbursement
efforts, including a registry of patients undergoing EsoGuard and a population study using electronic medical record screening to demonstrate
the clinical utility of an EsoGuard-driven strategy. We also will use the proceeds to support other studies of commercial value such
as the multi-center follow-up to the recently completed pilot clinical trial which suggested that EsoCheck may be an alternative to EGD
in managing Eosinophilic Esophagitis.</FONT></P>

developing our products and generating sufficient revenue in the timeframe set forth above, or at all. We may be unable to meet our targets
for research and development, regulatory approval and commercialization, or we may be unable to generate anticipated amounts of revenue

March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (&ldquo;CARES Act&rdquo;) was enacted in response to the pandemic
resulting from the outbreak of a novel strain of a coronavirus designated as the &ldquo;Severe Acute Respiratory Syndrome Coronavirus
2&rdquo; - or &ldquo;SARS-CoV-2&rdquo;. The pandemic resulting from SARS-CoV-2 is commonly referred to by its resulting illness of &ldquo;COVID-19&rdquo;

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Among
other provisions, the CARES Act increases the limitation on the allowed business interest expense deduction from 30 percent to 50 percent
of adjusted taxable income for tax years beginning January 1, 2019 and 2020 and allows businesses to immediately expense the full cost
of Qualified Improvement Property, retroactive to tax years beginning on or after January 1, 2018. Additionally, the CARES Act permits
net operating loss carryovers (&ldquo;NOLs&rdquo;) and carrybacks to offset 100% of taxable income for taxable years beginning before
2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable
years to generate a refund of previously paid income taxes. While the Company is currently evaluating the impact of these CARES Act provisions,
it is not expected, at this time, to have a material impact on the consolidated income tax provision.</FONT></P>

have begun to submit claims and receive out-of-network private insurance payments for EsoGuard. Consequently, we anticipate beginning
to generate revenues in 2021, however, our initial revenues likely will not be sufficient to finance our ongoing operations. Accordingly,
we expect to need additional capital in order to fulfill our business plan. In addition, there can be no assurance that we will be successful
in developing our products and generating sufficient revenue in the timeframe set forth above, or at all. We may be unable to meet our
targets for research and development, regulatory approval and commercialization, or we may be unable to generate anticipated amounts
of revenue from sales of our products. Additionally, available resources may be consumed more rapidly than currently anticipated. Should
any of these events occur, we may need to seek additional capital earlier or in greater amounts than anticipated.</FONT></P>

estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances,

an entity&rsquo;s ability to continue as a going concern within one year of the date of the financial statements are issued. In each
reporting period, including interim periods, an entity is required to assess conditions known and reasonably knowable as of the financial
statement issuance date to determine whether it is probable an entity will not meet its financial obligations within one year from the
financial statement issuance date. Under the provisions of ASC 205-40, substantial doubt about an entity&rsquo;s ability to continue

to meet its financial obligations as they become due within one year after the date the financial statements are issued.</FONT></P>

is a symptomatic or asymptomatic pathologic condition where dysfunction of the lower esophageal sphincter, the muscular valve between
the stomach and esophagus, and other factors allows stomach fluid, including acid, to reflux into the lower esophagus. The primary risk
factors for GERD are older age, obesity, smoking and a family history of BE-EAC. Up to 50 million, or one in four, U.S. adults, and similar
proportions worldwide, have weekly symptoms of GERD&mdash;most commonly a burning sensation in the lower chest (&ldquo;heartburn&rdquo;)
and/or acid regurgitation, usually after eating and exacerbated by laying down. Other symptoms include hoarseness, cough, wheezing, and
dental decay. Approximately one-third of these patients have daily symptoms. It is estimated that 40% of GERD patients, or about 30 million
U.S. adults, are completely asymptomatic. Proton pump inhibitor (PPI) medications&mdash;aggressively marketed under brands such as Prilosec<SUP>&reg;
</SUP>and Nexium<SUP>&reg;</SUP> and accounting for an estimated $13 billion in annual U.S. sales&mdash;effectively treat GERD symptoms
but do not prevent its complications and can lull patients and physicians into complacency.</FONT></P>

abnormal reflux of stomach fluid into the lower esophagus in GERD, whether symptomatic or asymptomatic, can result in pathologic changes
to its surface cells, which can progress along a spectrum from an early esophageal precancer known as Barrett&rsquo;s Esophagus (BE)
to EAC esophageal cancer. BE starts as a transformation of these lower esophageal surface cells from normal &ldquo;squamous&rdquo; to
&ldquo;columnar&rdquo; to &ldquo;metaplastic&rdquo; cells resembling the surface cells of the intestine, a condition called intestinal
metaplasia (IM). BE is characterized by a classic &ldquo;salmon-colored&rdquo; appearance of the lower esophagus on upper gastrointestinal
endoscopy, also known as esophagogastroduodenoscopy (EGD), extending 1 to 3 cm (short-segment BE) or over 3 cm (long-segment BE) from
its juncture with the stomach. A diagnosis of BE requires confirmation of intestinal-appearing cells via endoscopic biopsy.</FONT></P>

BE can further progress to dysplasia, a premalignant transformation characterized by abnormal intracellular and architectural features
on cytologic or histologic evaluation. Dysplastic BE starts as low-grade dysplasia (LGD) and can progress to high-grade (HGD) dysplasia.
NDBE, LGD, HGD and EAC constitute the BE-EAC spectrum from esophageal precancer (NDBE, LGD, HGD) to cancer (EAC).</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
prevalence of BE in GERD patients is approximately 5 to 15% depending on the risk profile. Although gender is not a risk factor for GERD,
male GERD patients are more likely to have BE and are at greater risk for progression to EAC. BE increases the long-term risk of EAC
30- to 40-fold. Linearized rates of progression along the BE-EAC spectrum vary in the published literature but a recent John Hopkins
study found that nearly 50% of BE patients will develop HGD or EAC over 10 years of follow up. However, it is important to note that
progression along the BE-EAC spectrum is not necessarily linear, which may explain why some patients develop interval EAC between surveillance
EGDs.</FONT></P>

common cancers progress along a similar well-established spectrum, from an early benign precancer such as NDBE, to a premalignant precancer
such as dysplastic BE, to early and then late-stage cancer, such as EAC. It is well established that the most effective way to prevent
cancer deaths is to implement early detection and intervention along such a cancer progression spectrum in at-risk patients. Death rates
from cancers which successfully utilize screening tools in early detection and intervention programs have declined nearly 50% in the
past three decades, including breast cancer (mammography), colon cancer (colonoscopy and more recently stool DNA tests) and cervical
cancer (Pap and human papilloma virus testing). In stark contrast, death rates from EAC, which have not benefited from a successful early
detection and intervention program, have remained relatively flat during this same period. Since mortality rates are high even in early
stage EAC, one must identify and intervene upon patients at the esophageal precancer (BE) stage to successfully prevent EAC deaths.</FONT></P>

    subgroup of GERD patients who are at-risk for complications and progression to EAC, and for whom screening for esophageal precancer
    is recommended, is also well defined. Guidelines published by the ACG, and other gastroenterology societies, recommend BE screening
    in patients with a five-year history of, or severe, GERD, along with three of six risk factors&mdash;age over 50 years, male gender,
    White race, obesity, smoking or a family history of BE-EAC. Its strongest recommendation is in men over 50 years with one other risk
    factor.</FONT></TD></TR>

despite recommendations in clinical practice guidelines, very few at-risk patients recommended for screening undergo traditional invasive
EGD, the standard diagnostic tool for esophageal disease. The EGD screening rate, even in the highest risk group, is estimated to be
significantly less than 10%. As a result, EAC is nearly always diagnosed only once it becomes invasive, causing pain, obstruction, weight
loss, bleeding, or other symptom of advanced disease. The near-death sentence of an EAC diagnosis typically comes as a complete shock,
with no hint that the patient&rsquo;s GERD had been silently progressing along the BE-EAC spectrum. We believe that the profound tragedy
of each newly diagnosed EAC case, is that the EAC and likely death could have been prevented if the at-risk GERD patient had been screened,
monitored with regular surveillance EGD, and undergone curative endoscopic esophageal ablation once dysplastic BE was detected.</FONT></P>

technologies underlying EsoGuard and EsoCheck were initially developed by a multidisciplinary team comprising three distinguished faculty
members at CWRU. Sanford Markowitz, M.D., Ph.D. is an internationally renowned medical oncologist and researcher, widely recognized for
his contributions in cancer genetics, personalized medicine, and cancer biology, who serves as a Distinguished University Professor and
Ingalls Professor of Cancer Genetics at Case Western Reserve University School of Medicine, and as a medical oncologist at University
Hospitals Cleveland Seidman Cancer Center. Dr. Markowitz&rsquo;s laboratory, which developed the EsoGuard assay, played a key role in
demonstrating that p53&mdash;a gene now recognized as the most common suppressor gene inactivated in human cancer&mdash;is a colon cancer
suppressor gene. His lab discovered other two key colon cancer suppressor genes and pioneered molecular tests of stool DNA for early
colon cancer detection. Dr. Markowitz&rsquo;s CWRU colleagues are Amitabh Chak, M.D., a prominent gastroenterologist and expert on esophageal

is a bisulfite-converted next-generation sequencing (NGS) DNA assay, performed on surface esophageal cells collected with EsoCheck, to
detect BE-EAC and is commercially available in the U.S. as an LDT. It quantifies an epigenetic change, aberrant cytosine methylation,
at 31 sites on two genes, vimentin (VIM) and cyclin A1 (CCNA1), which strongly correlates with the presence of all conditions along the
BE-EAC spectrum.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Aberrant
cytosine methylation, or simply methylation, is a non-mutational epigenetic process in which a methyl group attaches to a cytosine nucleotide
located within a CpG island, a region of high frequency CpG sites (cytosine followed by guanine) in the DNA sequence of a gene. Methylation
can modify a DNA molecule&rsquo;s function without a mutation in the DNA sequence itself. Methylation in a gene&rsquo;s promoter region
can inactivate its transcription. Methylation plays an important role in cancer initiation and progression, typically occurring in the
promoter region of tumor suppression genes, which makes it potentially useful as a cancer biomarker. Methylation can be detected and
quantified, after a chemical process called bisulfite conversion, without DNA sequencing using methylation-specific quantitative polymerase
chain reaction (MS-qPCR) techniques or, with greater precision by using next-generation DNA sequencing (NGS). Bisulfite conversion transforms
each methylated cytosine nucleotide into a uracil nucleotide, effectively transforming the aberrant cytosine methylation to a point mutation
on a given DNA molecule. Bisulfite NGS sequencing provides the methylation status for each CpG site on each DNA molecule in a sample.
MS-qPCR, however, does not provide such single CpG-site resolution, only the methylation status of a region of DNA across all DNA molecules
in a sample. Another advantage of bisulfite NGS sequencing over MS-qPCR is that it is able to suppress background noise from random methylation
of individual CpG sites.</FONT></P>

Markowitz&rsquo;s laboratory performed genome-wide screening, using reduced representation bisulfite sequencing, to identify regions
with differential aberrant cytosine methylation in conditions along the BE-EAC spectrum relative to controls. The laboratory first demonstrated
differential methylation at 10 sites within a CpG island on VIM, a gene long associated with gastrointestinal cancers. They then observed
similar differential methylation on 21 sites within a CpG island on CCNA1, a gene which had been associated with some cancers, most notably
myeloid leukemia, but not previously associated with gastrointestinal cancers.</FONT></P>

Markowitz and his colleagues then transformed these findings into a workable, reproducible assay. They chose to use NGS, instead of the
simpler MS-qPCR technique used in most clinical DNA methylation-based diagnostic tests. The NGS approach allowed them to determine the
methylation status for each of the 21 CpG sites on CCNA1 and 10 CpG sites on VIM on each DNA molecule. They then calculated the proportion
of methylated CpG sites on each gene of each DNA molecule, classifying each DNA molecule as either &ldquo;methylated&rdquo; or &ldquo;unmethylated&rdquo;
for that gene if that proportion of methylated CpG sites was above a specified threshold of 80% for each gene (at least 8 of 10 sites
for VIM or at least 16 of 21 sites for CCNA1). Finally, they calculated the percentage of DNA molecules in the sample which were methylated
at each gene and selected a cut-off percentage for each gene which optimally discriminates between BE-EAC and control samples. This provided
a binary result, positive if either gene was methylated above its own cut-off, and negative if neither gene was. The team encoded this
complex algorithm into a bioinformatics software package, incorporating numerous quality control checks, which translated the raw DNA
sequence reads into a binary positive or negative result.</FONT></P>

(low specificity), for both mVIM and mCCNA1, which occurred almost entirely in smokers. This finding was consistent with a large body
of data on smoking-induced aberrant DNA methylation in squamous epithelial cells of the oropharynx and esophagus. Reanalysis of lower
esophageal brushings reassuringly demonstrated that this degradation of assay performance in smokers was limited to the upper esophagus.</FONT></P>

data on poor assay specificity in upper esophageal brushings from smokers highlighted the importance of incorporating anatomic targeting
and protected sampling in any non-endoscopic esophageal sampling device which sought to use differential methylation to detect BE-EAC
in the lower esophagus. These data strongly imply that that anatomic targeting and protected sampling was not just critical to avoid
signal degradation from sample dilution, but, as importantly, to avoid contamination from upper esophageal methylation. This finding
was the impetus for developing a novel non-endoscopic swallowable balloon capsule catheter, which we now market as EsoCheck, to improve
on &ldquo;sponge-on-a-string&rdquo; devices like Cytosponge available at the time. Such sponge-on-a-string devices lack anatomic targeting
and lack protected sampling, the two critical features of EsoCheck we have branded Collect+Protect Technology.</FONT></P>

the team performed the assay on archived gastric and esophageal specimens of various of the gastroesophageal conditions with the potential
to confound the assay&rsquo;s results. It detected 80% of esophageal intestinal metaplasia (IM) shorter than the 1 cm threshold to qualify
as BE. It was also positive in 30% of samples with columnar cells, without histologic evidence of IM, from patients with BE detected
elsewhere in the esophagus. The assay was reliably negative in other conditions tested, including inflammatory conditions like gastritis
and eosinophilic esophagitis, with the notable exception of IM of the gastric cardia. These findings clearly suggest the assay detects
an aberrant methylation signal in the earliest phases of the transformation of surface esophageal cells into BE, even before histologic
evidence of IM. It also detects IM wherever it may occur, whether in ultrashort segments of esophagus or the gastric cardia. This was
confirmed in the data from balloon samples, with the assay detecting ultrashort IM and gastric IM with the same 88% sensitivity as it
did with BE-EAC samples. This may be clinically relevant even though these are technically false positives based on the most widely
accepted definition of BE. Finally, the assay was positive in one-third of patients with normal endoscopy following ablation for
dysplastic BE, indicating that the assay may play a role in monitoring patient for recurrent IM after ablation.</FONT></P>

summary, Moinova, <I>et al</I> demonstrated that the mVIM/mCCNA1 NGS DNA methylation assay we now market as EsoGuard was highly accurate
at detecting all conditions along the BE-EAC spectrum, including on samples collected with the novel swallowable balloon capsule catheter
we now market as EsoCheck. The performance of EsoGuard performed on samples collected with EsoCheck was clearly superior to two published
reports of the performance of TFF-3 performed on samples collected with Cytosponge &ndash; one funded by its manufacturer Medtronic and
the other by the U.K. group which invented it &ndash; with overall sensitivities of 76% and 80% and overall specificities of 77% and
92%. The study has certain limitations. It was performed at a single tertiary care institution which may impact its generalizability
to a community setting. The study population consist predominantly of White males which may impact its generalizability in females and
non-Whites, in which BE is less common. Large ongoing clinical trials seek to replicate these results, including a prospective screening
study of at-risk GERD patients.</FONT></P>

(CDO) model to provide integrated, turnkey solutions to life sciences companies seeking to develop proprietary diagnostic tests. ResearchDx
operates a full-service CLIA-certified clinical laboratory called PacificDx, for clients, like us, who seek to commercialize their test
in the clinical setting. PacificDx finalized the transfer of the EsoGuard assay SOPs from Dr. Markowitz&rsquo;s laboratory and implemented
them with only minor modifications to enhance workflow in a commercial setting. In December 2019, PacificDx, completed the documentation
of analytical validity of the EsoGuard assay on cell lines and clinical samples, including banked samples from the CWRU case-control
study reported in the Science Translational Medicine manuscript and described above. It included head-to-head comparisons of the assay
performed on such clinical samples at PacificDx and repeated at the NGS laboratory Dr. Markowitz&rsquo;s team used in their study. This
analytic validity work was performed pursuant to CLIA regulations, allowing us to commercialize EsoGuard in the U.S. as an LDT.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">We
subsequently entered into a services contract with PacificDx to receive samples from clinical sites performing the EsoCheck procedure,
perform the EsoGuard test on the sample, generate a patient report indicating a positive or negative result along with guidance on interpreting
the results based on published data, send the report to the prescribing physician, and bill and collect payment from the patient or its
insurer. The contract provides a maximum turnaround time and a volume-based per-test cost schedule which account for the fact the maximum
turnaround time would require running partially full trays until volume increased and was consistent. The cost structure provides us
with an attractive gross margin at volume. The contract was recently modified to accommodate certain regulations related to our upcoming
Lucid Test Centers and EsoGuard Telemedicine Program. It was restructured as a sublicense of the EsoGuard technology to PacificDx whose
payments to us from net proceeds of the test will constitute a sublicense and reimbursement fee, with PacificDx bearing reimbursement
risk subject to periodic adjustments.</FONT></P>

consists of a vitamin pill-sized, silicone-covered rigid plastic capsule tethered to a soft, thin silicone catheter from which a soft
textured silicone balloon emerges. When inflated the balloon&rsquo;s textured ridges can gently swab surface esophageal cells. The proximal
end of the catheter is connected to a syringe that delivers a specified volume of air into the balloon, either 11 cc. to engage the gastroesophageal
junction for anatomic indexing, or 5.6 cc. for distal esophageal cell sampling. Applying vacuum suction with the syringe pulls and inverts
the balloon into the capsule along with sampled cells adhered to the balloon&rsquo;s surface, protecting the sample from contamination
and dilution from cells outside of the targeted region during device withdrawal, including non-BE upper esophageal cells which can be
methylated in smokers. We believe this proprietary Collect+Protect<SUP>&trade;</SUP> technology makes EsoCheck the only noninvasive esophageal
cell collection device capable of such anatomically targeted and protected sampling. Such precise sampling is necessary to accurately
detect the low-level pathologic signal seen in early esophageal precancer.</FONT></P>

to Covidien, which was later acquired by Medtronic Inc. Despite numerous clinical studies and a brief but aggressive marketing push by
Medtronic, Cytosponge/TFF3 has failed to live up to its promise as a widespread screening tool for BE-EAC. Dr. Nick Shaheen, who chairs

previously stated, the CWRU team&rsquo;s data on poor assay specificity in upper esophageal brushings was the impetus for them to develop
a non-endoscopic esophageal sampling device incorporating anatomic targeting and protected sampling of lower esophageal cells. They realized
that these two features were critical to avoid signal degradation from dilution and/or contamination of the lower esophageal sample by
cells in the unaffected areas of the upper esophagus, throat, and mouth. None of the prior or current non-endoscopic tools seeking to
serve as widespread BE-EAC screening tools &ndash; Wilson-Cook&rsquo;s Brandt Balloon, Medtronic&rsquo;s Cytosponge, and Capnostics&rsquo;
EsophaCap &ndash; incorporated these features and therefore suffered from such sample dilution and contamination. The CWRU team was able,
for the first time, to incorporate these critical features, which we have branded Collect+Protect Technology, into a non-endoscopic tool
for BE-EAC screening, which we now market as EsoCheck, in a simple, elegant, and operator/patient-friendly manner.</FONT></P>

After a few minor design modifications, we proceeded to a survival GLP porcine study that included side-by-side comparison testing
between EsoCheck and the Hobbs Medical Inc. Single-Use Cytology Brush. The study was designed to evaluate the performance of EsoCheck
and the Hobbs Brush, using pre-defined acceptance criteria including the number of captured cells and visual/histologic evidence of esophageal
trauma. Each of four animals studied underwent sampling of four randomly assigned segments of the esophagus, two with EsoCheck and two
with the Hobbs Brush. A board-certified pathologist with subspecialty board certification in gastrointestinal cytopathology reviewed
the slides and determined cell counts using standard techniques. EsoCheck collected over twice as many cells as the Hobbs Brush, over
25,000 versus over 11,000, respectively. Endoscopic visualization rated esophageal trauma at &le;2 on a 0 to 5 scale per the Esophageal
Injury Scale, adapted from The American Association for the Surgery of Trauma. Histopathologic analysis of the gastroesophageal junction
showed normal mucosal lining in all animals.</FONT></P>

then developed an EsoCheck supply chain and selected Sage Product Development as our contract manufacturer with other suppliers and service
providers serving as subcontractors to Sage. We then completed the remaining steps necessary to proceed with regulatory submission and
commercialization including pre-verification testing, design verification and validation testing, and manufacturing process development
and validation. Verification testing included visual and dimensional inspection, balloon capsule assembly measurement, balloon inflation/deflation
tests, balloon burst tests, balloon inversion tests, bond tests, tensile tests, and the side-by-side GLP animal testing of cell count
yield and tissue trauma. Validation testing included biocompatibility testing (ISO 10993), sterilization lot release testing (EO), packaging

vast majority of at-risk GERD patients are cared for by PCPs and never see a gastroenterologist. We believe for us to have a meaningful
impact on preventing EAC deaths, we will need to find the at-risk GERD patients where they are located&mdash;at the PCP practice. We
have the opportunity to educate PCPs that GERD can lead to EAC, and that, for the first time, they can refer their at-risk GERD patients
for testing using a non-endoscopic alternative to EGD&mdash;a brief office-based test to accurately detect esophageal precancer and prevent
progression to highly lethal EAC. We believe our upcoming Lucid Test Centers will play a critical role in significantly growing EsoGuard

GERD and BE-EAC, and the availability of a simple noninvasive test to detect esophageal precancer, will encourage those at risk to explore
EsoGuard testing. We intend to use proceeds from this proposed offering to launch a pilot EsoGuard Telemedicine Program with DTC marketing
in Phoenix and expand it to other metropolitan areas once we demonstrate an acceptable return on investment. We view our plan to target

after our inception, our parent company, PAVmed determined that it owned intellectual property, its Caldus portfolio developed by its
co-founders, that could be applied to endoscopic esophageal ablation. PAVmed&rsquo;s EsoCure Esophageal Ablation Device with Caldus&trade;
Technology is designed to be synergistic with our EsoGuard and EsoCure products, and together would offer the only comprehensive panel
of products capable of detecting and treating conditions across the BE-EAC spectrum.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Commercially
available devices for endoscopic esophageal ablation use radiofrequency (RF) or cryoablation and rely on complex and expensive consoles
and/or gas tanks to perform the ablation. Capital equipment costs are high including up to $200,000 for the market leader in this space,
the Medtronic Barrx system. These devices often require multiple introductions and removals of the endoscope, sizing catheter and ablation
balloons, which is labor-intensive, time consuming and uncomfortable for the patient.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">In
contrast, EsoCure is designed to use a disposable, single-use direct thermal balloon ablation catheter which, unlike the Barrx circumferential
RF balloon catheter, is designed to advance through the working channel of a standard endoscope and not require manipulation once inserted.
The balloon is positioned and inflated in the distal esophagus under endoscopic vision, confirming good circumferential esophageal contact
and complete coverage of all visible BE tissue. The catheter is then connected to an inexpensive console which incorporates the patented
Caldus technology. The system circulates heated fluid from a fluid cartridge in the console, through the catheter, to the balloon and
the back up to the cartridge allowing the balloon to ablate and destroy the abnormal surface esophageal cells of the targeted region
by directly heating them above their cytotoxic threshold for a specified period of time. This direct thermal cytotoxic mechanism is biologically
identical to RF ablation, but without the intermediate use of electrical energy. EsoCure is designed to maintain a very high balloon
temperature, higher than temperatures associated with RF ablation, which we believe may permit very low ablation times and enhance procedural
safety and efficiency. Eliminating endoscope changes and the need for complex, expensive capital equipment has the potential to we believe
will make EsoCure much more efficient and cost-effective than Barrx or other esophageal ablation devices.</FONT></P>

status as a commercially available LDT is dependent on an uncertain regulatory landscape for LDTs. FDA has long maintained that it has
clear regulatory authority over LDTs but has exercised enforcement discretion for most LDTs and has generally not required most LDTs
to undergo FDA premarket review of analytical validity and clinical validity. For over a decade, FDA has expressed its concern about
insufficient regulatory oversight over LDTs but, despite multiple non-binding communications and documents, it has never issued a final
guidance document on the regulation of LDTs and has continued its enforcement discretion largely substantially unchanged. In August 2020,
the Department of Health and Human Services (HHS) announced that, effective immediately, it was rescinding all documents and issuances
concerning FDA premarket review of LDTs, and that FDA may not require premarket review of LDTs absent a formal notice-and-comment rulemaking
process. This directive notwithstanding, the regulatory landscape for LDTs such as EsoGuard remains uncertain. The Verifying Accurate
Leading-edge IVCT Development (VALID) Act which seeks to revamp the regulatory framework of diagnostic tests, including LDTs, has been
reintroduced in 2021 and could alter this landscape it becomes law.</FONT></P>

into approximately 500 to 900 patients which is powered to detect NDBE within our targeted success criteria defined by the lower bound
of the 95% confidence interval of sensitivity. We also proposed a secondary case control study with four categories of cases, short-segment
NDBE, long-segment NBDE, LGD, HGD and early EAC, to document performance in each condition along the BE-EAC spectrum, since the more
advanced conditions will be underrepresented in the screening study. We received, and the final approved minutes reflect, favorable FDA

contract provided a volume-based per-test cost schedule which accounts for the fact that the maximum turnaround time would require running

The contract was recently modified to accommodate certain regulations related to our upcoming Lucid Test Centers and EsoGuard Telemedicine
Program. It was restructured as a sublicense of the EsoGuard technology to PacificDx whose payments to us from net proceeds of the test
will constitute a sublicense fee, with PacificDx bearing reimbursement risk subject to period adjustments.</FONT></P>

is subject to U.S. and state laws and regulations regarding the operation of clinical laboratories. CLIA requirements and laws of certain
states, including those of California, New York, Maryland, Pennsylvania, Rhode Island and Florida, impose certification requirements
for clinical laboratories, and establish standards for quality assurance and quality control, among other things. CLIA provides that
a state may adopt different or more stringent regulations than federal law and permits states to apply for exemption from CLIA if the
state&rsquo;s laboratory laws are equivalent to, or more stringent than, CLIA. Notably, the State of New York&rsquo;s clinical laboratory
regulations, which have received an exemption from CLIA, contain provisions that are in certain respects more stringent than federal
law. Therefore, as long as New York maintains a licensure program that is CLIA-exempt, PacificDx will need to comply with New York&rsquo;s
clinical laboratory regulations in order to offer our clinical laboratory products and services in New York and perform EsoGuard testing
on samples collected in New York.</FONT></P>

such as Health Information Data and Information Set (&ldquo;HEDIS&rdquo;) and CMS Star Ratings, to assess quality of care. We will seek

utilizes its Clinical Laboratory Fee Schedule (CLFS) process, pursuant to 42 CFR &sect; 414.506-509, to determine payment for clinical
laboratory tests, including LDTs such as EsoGuard. From time to time, Congress has revised the Medicare statute, including how CMS establishes
CLFS payment rates. The payment amounts established under the Medicare fee schedules (such as the CLFS) are important because they determine
the amount of reimbursement for a diagnostic test under Medicare, and those payment amounts are also often used as a basis for payment

However, CDLT prices are adjusted every three years (based on updated reporting) whereas ADLT prices are adjusted annually. The other
difference between the two types of tests is the methodology used to establish the initial Medicare payment rate. For CDLTs, the CMS
establishes the initial payment rate via the crosswalk or gap-fill methodology. For ADLTs, the price paid for the first three calendar
quarters after a test&rsquo;s designation as an ADLT is the test&rsquo;s actual list charge (<I>i.e.</I>, the publicly available rate

are also seeking reimbursement from private payors such as health insurance companies and integrated healthcare networks. Private payors
generally will determine whether to approve an LDT for reimbursement based on the published results demonstrating the analytical validity,
clinical validity, and clinical utility of the test. Reimbursement rates paid by private third-party payors can vary based on whether
the provider is considered to be an &ldquo;in-network&rdquo; provider, a participating provider, a covered provider, an &ldquo;out-of-network&rdquo;
provider or a non-participating provider. These definitions can vary among payors. An in-network provider usually has a contract with
the payor or benefits provider. This contract governs, among other things, service-level agreements and reimbursement rates. In certain
instances, an insurance company may negotiate an in-network rate for our testing. An in-network provider may have rates that are lower
per test than those that are out-of-network, and that rate can vary widely. Rates vary based on the payor, the testing type and often
the specifics of the patient&rsquo;s insurance plan. If a laboratory agrees to contract as an in-network provider, it generally expects
to receive quicker payment and access to additional covered patients. However, it is likely that we will initially be considered an &ldquo;out-of-network&rdquo;
or non-participating provider by payors who cover the vast majority of patients until we can negotiate contracts with the payors. Our
out-of-network claims may be subject to certain &ldquo;surprise billing&rdquo; restrictions enacted by state legislatures and/or currently
under consideration in the U.S. Congress.</FONT></P>

third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Third-party
payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for new healthcare
products. As a result, there is uncertainty surrounding whether EsoGuard or EsoCheck, or any other product or service we develop, license,
or acquire will be eligible for coverage by third-party payors or, if eligible for coverage, what the reimbursement rates will be. Reimbursement
of esophageal cancer screening by a third-party payor may depend on a number of factors, including a payor&rsquo;s determination that
tests using our technologies are sufficiently sensitive and specific for esophageal precancer and cancer, not experimental or investigational,
approved or recommended by the major guideline-writing organizations, reliable, safe and effective, medically necessary, appropriate
for the specific patient, and cost-effective.</FONT></P>

to secure payment and coverage and found their expectations to align with our planned studies, including a large EsoGuard registry we
are preparing to launch. Another important topic regarded implementing mechanisms to assure that EsoGuard testing is performed, and billed
for, consistent with practice guidelines. We discussed our commitment to help control unindicated testing, working collaboratively with
payors through audits and risk-sharing arrangements as needed. They indicated that, by establishing strict, evidence-based criteria for
who will undergo the EsoCheck procedure for EsoGuard testing, our proposed Lucid Test Centers had the potential to serve as an important

of two pillars of our overall growth strategy, which are the impetus for this public offering, is to expand EsoGuard commercialization
across multiple channels including targeting primary care physicians in addition to GI physicians. Although we have focused our commercialization
efforts to date on the latter to build critical alliances with the GI community as full partners in our efforts, we have always been
keenly aware that nearly all GERD patients are exclusively cared for by primary care physicians (PCP) and only a very small proportion
of them ever see a GI physician. Despite a growing interest in GERD in the PCP community, very few PCPs understand that GERD can lead
to EAC. To the extent that they have much awareness of BE, there is a broad assumption that it is an entirely benign condition, a medical
oddity in which cells of one organ, the esophagus, begin to look like cells of another, the intestines, but certainly not a precancer
that can lead to one of the most lethal cancers whose incidence has exploded over recent decades. The general focus of most PCPs in GERD
appears to be symptomatic relief. Most PCP referrals to GIs for EGD is to evaluate intractable GERD symptoms and escalate treatment,
including more aggressive medical therapy, endoscopic or surgical intervention. The extremely low referral rate of at-risk GERD patients
for screening EGD is likely, as much as anything, due to the fact that PPIs like Prilosec<SUP>&reg;</SUP> and Nexium<SUP>&reg; </SUP>are
so effective at controlling, or at least mitigating, GERD symptoms.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Notwithstanding
this current landscape, we believe that PCPs will be receptive to widespread BE-EAC screening of at-risk GERD patients to prevent EAC
deaths, once they are educated on the relationship between GERD and EAC, professional society guidelines for such screening, and the
availability of a new, simple, non-endoscopic office-based procedure to test patients for BE-EAC using a highly accurate and sophisticated
molecular diagnostic test. This conviction is partially based on our limited but successful experience engaging with a few large primary
care practices, one of which quickly established their own EsoCheck program and promoted it to patients through educational open houses.
We have also begun calling directly on a limited number of PCPs in the Phoenix area, again with very positive results. Our message to
PCPs is very simple and very different than our message to the GIs. We are not asking them to dedicate the resources to performing EsoCheck
testing in their office, except for very large practices where weekly procedural volumes could justify a dedicated trained clinician
to perform them. We are simply asking them, after educating them, to embrace the professional society recommendations and consider referring
their at-risk GERD patients for EsoGuard testing. Of course, Exact Sciences, which markets the stool DNA colon cancer detection test
Cologuard, and others in the early cancer detection space, have relied on such a PCP channel to drive their sales growth.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">We
have determined that, over the long run, the only way to assure sufficient testing capacity and geographic coverage to accommodate this
PCP expansion, and assure that any patient referred by a PCP has access to EsoGuard testing if clinically appropriate, is to create our
own network of Lucid Test Centers staffed by Lucid clinical personnel, where patients can be referred to undergo the EsoCheck procedure
and have the sample sent to our CLIA-certified laboratory partner for EsoGuard testing.</FONT></P>

the regulatory, compliance and logistical complexities of such an effort, we have decided to first proceed with a pilot program in one
major metropolitan area. We have hired clinical personnel and leased medical office space to launch three pilot Lucid Test Centers in
the Phoenix metropolitan area. We expect to begin seeing patients referred by local physicians at these Centers soon, once we have finalized
the requisite regulatory and compliance infrastructure.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">We
have paid careful attention to these regulatory and compliance requirements and have gone to great efforts to assure that we have a robust
such infrastructure in place prior to formally launch the Centers. To that end, we have retained highly experienced dedicated healthcare
regulatory and compliance counsel to assist us with this, culminating in a detailed memo outlining precisely how each element of the
program complies with specific regulatory acts and regulations described in detail later in this prospectus. This effort has also included
adding dozens of new SOPs to our quality management system, covering all aspects of the program. As noted previously, upon advice of
counsel and out of an abundance of caution, we revised certain elements of our contractual agreement with our CLIA-certified laboratory
partner to align with certain regulations. Finally, we established a new Quality &amp; Compliance Committee of our board of directors
to provide board-level oversight of this process and recruited Dr. Jacque Sokolov to serve on our board and chair the committee. Dr.
Sokolov has long been a strong advocate of Board oversight of compliance and quality for public healthcare companies and has established
and chaired such committees for several major healthcare companies including Hospira Inc. (NYSE: HSP) until it was acquired by Pfizer
Inc. (NYSE: PFE). Joining Dr. Sokolov and other board member on the committee are Dr. DeGuzman, our Chief Compliance Officer, our outside
general counsel, aforementioned outside healthcare compliance counsel, Dr. Alberto Gutierrez, who led the <I>in-vitro</I> diagnostic
branch at FDA, and his former colleague DC-based attorney Jeff Gibbs who previously served as FDA Associate General Counsel for Enforcement.</FONT></P>

completing the pilot program in Phoenix, we intend to use proceeds from this proposed offering to steadily expand our Lucid Test Centers,
first in Western U.S. states, most of which, with the exception of California, allow nurse practitioners to fully practice without physician
supervision. Although we have no formal plans to do so and have not engaged with any such parties, we may explore and eventually seek
joint-ventures with laboratory testing companies as well as pharmacy mini-clinic networks to establish EsoGuard testing capacity at their
facilities.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Our
analysis indicates that the economics of our proposed Lucid Test Centers should be attractive. We estimate that a single nurse practitioner,
supported by a medical assistant, will be able to perform up to twenty EsoCheck procedures per day. The number of procedures per clinician,
per center, necessary to cover the personnel costs and medical office leases is very modest. Assuming payor reimbursement becomes acceptable,
once that threshold volume is reached and, the program costs become strictly marginal.</FONT></P>

materials targeting GI physicians, PCPs, and consumers across all media including in professional journals, printed patient educational
materials, printed physician marketing materials, infographics, material for social media, and audio video materials. The latter include
two professionally filmed and edited powerful patient testimonials, one of which aired on cable networks, and another was just recently
completed. The team has also created a lively and engaging animated EsoGuard mascot, Frederick &ldquo;Freddie&rdquo; E. Foodtube who
educates consumers on GERD and BE-EAC and encourages them to &ldquo;Check Your Foodtube&rdquo;. Freddie is already quite active on social

growth strategy to expand EsoGuard commercialization across multiple channels includes targeting consumers, in addition to PCPs and GI
physicians. The success of EsoGuard will depend, not only on educating PCPs on the relationship between GERD and BE-EAC, but also the
broader public through direct-to-consumer (DTC) efforts. Although it will take substantial resources and effort to do so, the message
is not a difficult one, at least compared to widespread DTC marketing of obscure biopharmaceuticals treating obscure medical conditions,
or even compared to Exact Sciences&rsquo; aggressive DTC marketing of its stool DNA test, Cologuard, which does require communicating
certain nuances. In our case, patients definitely understand chronic heartburn, or GERD, as they are already bombarded with advertising
for symptomatic relief including antiacids and PPIs. Consumers also definitely understand cancer, as most have some family experience
with the number two cause of death in the U.S. We are confident that educating consumers on the link between GERD and BE-EAC, the risk
factors which drive it, and the availability of a simple noninvasive test to screen for esophageal precancer will encourage those at
risk to at least inquire about their options. We have already seen this on a modest scale, as our early presence on social media has
already generated a small but growing stream of self-referrals for EsoCheck testing.</FONT></P>

order to accommodate consumers who self-refer for EsoGuard testing in response to our DTC advertising of our products, we need to provide
them with an arms-length independent physician who can evaluate them and determine whether referral for EsoGuard testing is clinically
appropriate. The most effective and efficient way to do so in this era is by contracting with one or more third-party telemedicine companies
who will provide physicians to evaluate the consumer via video communications and determine whether EsoGuard testing is clinically indicated
based on their history and condition. If so, they can order an EsoGuard test by referring the patient to one of our Lucid Test Centers
where the patient would undergo EsoCheck specimen collection by our clinical personnel for EsoGuard testing by our third-party CLIA-certified
laboratory partner. The EsoGuard test result would then be sent directly to the prescribing telemedicine physician who, based on the
test result, would refer the patient to a gastroenterologist for further care.</FONT></P>

logistics required to manage the patient&rsquo;s journey through such a DTC/telemedicine program, in a manner which is compliant with
all applicable regulations, are complex and require very careful coordination between us, and our third-party telemedicine and laboratory
partners, all operating within our quality management system. Our activities, and the activities of our third-party partners within this
DTC/telemedicine program on our behalf, is subject to numerous federal and state regulations. The telemedicine provider itself may be
subject to additional state regulations relating to the corporate practice of medicine, test orders, patient consents, medical necessity
requirements and billing regulations. Telemedicine, and its specific use in conjunction with DTC, faces particularly intense scrutiny
from regulators due to numerous cases of companies failing to operate in this space with a properly functioning regulatory and compliance
infrastructure. For example, in recent years, the federal government has conducted several major investigations into the use of telemedicine
to generate orders or prescriptions for laboratory tests, pharmaceuticals, durable medical equipment and other ancillary items and services
that are billed to Medicare and other federal health care program (FHCPs). In such cases, the supplier that received the order or prescription
and billed for the ancillary item or service would compensate the telemedicine provider (or management company) for the patient consultation
because the actual telehealth service may not be a covered service or meet the coverage requirements under the Medicare or other FHCPs
(due to lack of provider-patient relationship or audio-only modality). The Department of Justice has prosecuted providers on the legal
theory that this is akin to a kickback or bribe in the form of remuneration paid to the telemedicine provider or management company for
the order or prescription itself, whether the ancillary item or service was medically necessary.</FONT></P>

believe our lead product, the EsoGuard Esophageal DNA Test, performed on samples collected with our EsoCheck Cell Collection Device,
constitute the first and only commercially available diagnostic test capable of serving as a widespread screening tool to prevent EAC
deaths through early detection of esophageal precancer in at-risk GERD patients, and that EsoCheck&rsquo;s Collect+Protect&trade; technology
makes it the first and only noninvasive device capable of anatomically targeted and protected sampling of the esophagus, which prevents
sample dilution and contamination during device withdrawal, and which is necessary to accurately detect early esophageal precancer.</FONT></P>

current standard for diagnosing esophageal precancer (BE) is traditional upper gastrointestinal endoscopy (EGD), with multiple systematic
biopsies of areas of the lower esophagus which have the characteristic &ldquo;salmon-colored&rdquo; appearance. Despite being widely
available for many decades, EGD has failed as a widespread screening tool for esophageal precancer. This is in stark contrast to is lower
gastrointestinal counterpart colonoscopy, which is successfully utilized as a widespread screening tool for colon precancer (polyps)
and cancer. Nearly 70% of at-risk patients recommended for colon precancer and cancer screening by clinical practice guidelines undergo
colonoscopy, while less than 10% of at-risk GERD patients who are recommended for esophageal precancer screening undergo EGD. This is
likely due to multiple factors including that EGD is performed under intravenous sedation or anesthesia in a specialized facility and
that both the patient and someone accompanying them must take a day off.</FONT></P>

currently available alternatives to EGD which are commercially available in the U.S. have also failed to be adopted as widespread screening
tools for esophageal precancer. Transnasal endoscopy (TNE) is similar to EGD but uses a smaller caliber endoscope which can be inserted
into the esophagus through the nose and can visually assess the lower esophagus for areas with an abnormal &ldquo;salmon-colored&rdquo;
appearance. TNE can be performed in an office setting without intravenous sedation or anesthesia, but the small-caliber endoscope typically
does not have a working port through which biopsies can be taken. Capsule endoscopy is performed using a large capsule embedded with
a camera which the patient swallows. Images of the esophageal lining are captured and transmitted as the capsule traverses the lower
esophagus. Despite some early hope, neither TNE nor capsule endoscopy have been adopted as widespread screening tools for esophageal
precancer, likely due to the fact that both depend entirely on imaging and do not provide cell or tissue samples.</FONT></P>

manufactures have developed noninvasive esophageal cell collection devices most notably &ldquo;sponge-on-a-string&rdquo; devices which
may compete with EsoCheck. Two such devices, Cytosponge, previously marketed in the U.S. by Medtronic Inc. (NYSE: MDT), and EsophaCap,
manufactured by Capnostics Inc. and utilized almost exclusively for clinical research, are spherical mesh sponges encapsulated in soluble
gelatin that dissolve in the stomach. The expanded sponge brushes the lining of the esophagus as it is withdrawn and retrieved. Unlike
EsoCheck, these devices do not provide anatomic targeting nor protect their sample from dilution and contamination during device withdrawal.
It is possible that future biomarkers may have sufficient sensitivity to detect esophageal precancer despite such dilution and contamination
or that manufacturers may develop and commercialize new tools, not yet disclosed, which provide noninvasive esophageal cell sampling
with the same or better protection from dilution and contamination as EsoCheck. However, we believe that, for the foreseeable future,
EsoCheck will remain the only esophageal cell collection device with the precision sampling necessary to detect early esophageal precancer
with sufficient accuracy to serve as part of a widespread screening tool.</FONT></P>

only commercially available test which has been assessed for use as part of a widespread esophageal precancer screening tool is the nonproprietary
immunohistochemical test Trefoil Factor 3 (TFF3). Although any laboratory can perform this test, it has historically been performed on
cell samples collected using Cytosponge which is no longer commercially available in the U.S. Although TFF3/Cytosponge showed some ability
to detect BE, it performed poorly in short segment BE (&lt; 3 centimeters), which is common in a screening population, and its overall
performance (estimated negative predictive value) fell far short of what would be needed for it to serve as a widespread esophageal precancer
screening tool. In addition, unlike molecular diagnostic tests like EsoGuard, immunohistochemical tests like TFF3 incorporate human subjectivity
and are difficult to automate and process with high throughput, both important considerations for widespread screening tools.</FONT></P>

we do not believe we face meaningful competition from currently available modalities, given the large market opportunity for esophageal
precancer screening we may face multiple competitors in the future. For example, our EsoGuard test may face competition from new biomarkers
also designed to detect esophageal precancer and conditions along the BE-EAC spectrum. The Mayo Clinic and Exact Sciences Inc. (Nasdaq:
EXAS) have published preliminary data on such biomarkers and have publicly expressed a commitment to advancing them to commercialization.
Investigators at Johns Hopkins University associated with a privately held firm called Caplusomics have published limited data on methylation
biomarkers for BE. Of note, both groups used the EsophaCap &ldquo;sponge-on-a-string&rdquo; cell collection device.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Several
well-capitalized companies are developing &ldquo;liquid biopsy&rdquo; tests for early cancer detection based on circulating tumor DNA.
Most of these companies are focused on multicancer detection, or a single cancer other than esophageal cancer. Since mortality rates
are high even in early stage EAC, one must identify and intervene upon patients at the precancer stage to prevent EAC deaths. Detecting
early precancer in the bloodstream is a major biological challenge and we are not aware of any liquid biopsy test that purports to do
so. By definition, precancers like BE do not penetrate the surface cellular layers which is necessary for abnormal cells to enter the
blood stream. In principle the only way precancer DNA can enter the bloodstream is within tiny packets called exosomes which are shed
from cells. Furthermore, early precancers, such as BE, are not characterized by genomic mutations or other genetic changes that can be
easily detected in minute quantities of circulating DNA. EsoGuard detects subtle epigenetic changes in BE called methylation. Although
technological advances could result in sufficient sensitivity to detect such subtle BE epigenetic changes in minute quantities of circulating
DNA, we believe the biologic hurdles make it unlikely that a viable esophageal precancer screening &ldquo;liquid biopsy&rdquo; test will
emerge in the foreseeable future. If such a test did emerge and was successfully commercialized, it could put EsoGuard and EsoCheck at
a significant competitive disadvantage since logistically it would be much simpler to send the patient for a routine blood draw instead
of a specialized office procedure like EsoCheck, and patients would generally prefer such a blood draw over even a noninvasive procedure
such as EsoCheck.</FONT></P>

still unproven, technologies with the potential to compete with EsoGuard and EsoCheck in the future, include breath tests and oral tests
which purport to detect BE. For example, there is early data to suggest that an &ldquo;electric nose&rdquo; device which measures volatile
organic compounds (VOCs) developed by Aeonose, The eNose Company, based in the Netherlands, may be able to detect BE. Preliminary published
data from Columbia University School of Medicine found differences in the oral bacterial microbiome, obtained with a simple saliva sample
or oral swab, may correlate with the presence of BE.</FONT></P>

there can be no assurance that we will pursue any products other than EsoGuard and EsoCheck, if we seek to develop, license, or acquire
other products, we may need to compete with a broad range of organizations in the U.S. and other countries that are engaged in the development,

general, we may be unable to compete effectively against our potential competitors either because their products and services are superior
or more cost efficient, or because they have access to greater resources than us. Our potential competitors may have substantially greater
financial, marketing, sales, distribution, manufacturing, and technological resources. These competitors may also have broader product
lines and greater name recognition than we do. Many of these competitors will have obtained FDA or other regulatory clearances or approvals,
and patent protection, for their products, or are in the process of seeking such clearances, approvals, and protection. Certain of our
potential competitors may commercialize their products in advance of our products. In addition, our competitors may make technical advances
that render our products obsolete. We may be unable to respond to such technical advances, especially given our focus on the EsoGuard
and EsoCheck technology. Although there can be no assurance that we will pursue the development of any products other than EsoGuard and
EsoCheck, even if we do develop new marketable products or services, our current and future competitors may develop products and services
that are more commercially attractive than ours, and they may bring those products and services to market earlier or more effectively
than us.</FONT></P>

a contracted clinical research organization based in Europe which has managed personnel, data, and documentation for our clinical trials.
We are now internalizing much of this activity to optimize efficiency and scalability, as well as gain full control of the process, as
we expand our clinical trial activities consistent with our growth strategy. We have begun to hire a core group of clinical research
associates as full-time employees and will continue to do so as our needs grow. We recently engaged a leading data management vendor

our current efforts commercializing EsoGuard as an LDT are going well, we believe, over the long-term, it would be useful to jointly
market EsoGuard, used with EsoCheck, as a combined product. We, therefore, have decided to pursue FDA PMA approval for EsoGuard, used
with EsoCheck, as an IVD, which will allow us to jointly market them as well as provide protection against any upcoming changes to LDT
regulation which could affect our ability to market EsoGuard as an LDT in the future. As importantly, in addition to their regulatory
value, the clinical trials required for us to gain PMA approval will be the first and most important expansion of the clinical evidence

Esophagus due to chronic GERD for at least 5 years and one other risk factor, including Caucasian race, body mass index &gt;30, chronic
tobacco smoking, or a first-degree relative with Barrett&rsquo;s esophagus or esophageal adenocarcinoma. A positive result may additionally
indicate the presence of low-grade or high-grade dysplasia and/or esophageal adenocarcinoma. EsoGuard, on samples collected using EsoCheck,

proposed primary screening study would assess the test&rsquo;s performance in detecting all conditions along the BE-EAC spectrum in a
screening population but would only be powered to detect NDBE. The initial patients in each group in the proposed supporting case control
study, distributed across groups consistent with their incidence in a screening population, would also serve as a training set to establish
new cutoffs for the assay tailored to such a screening population. The remain patients in the proposed supporting case control study
would confirm the test&rsquo;s performance across the BE-EAC spectrum, including the more advanced conditions which will be underrepresented
in a screening population. We also discussed enrolling a meaningful proportion of patients in either study from European countries. We
received, and the final approved meeting minutes reflect, positive and constructive FDA feedback on our proposed initial indication for
use and the design of our proposed clinical studies, including well-defined success criteria for each study. Based on this feedback we
decided to proceed with our two international multicenter PMA studies, ESOGUARD-BE-1 and ESOGUARD-BE-2. Dr. Shaheen agreed to serve as
our study-wide Principal Investigator for both studies. Some of the details of the studies are summarized below.</FONT></P>

to our Breakthrough Device discussions with FDA, we intend to extend enrollment in the ESOGUARD-BE-1 screening study until it is sufficiently
powered to support expansion to the above proposed indication for use to include detection of dysplastic BE. FDA indicated that although
they would have preferred to a study powered for HGD, they understood that the study size would be impracticable and that they would
be open to including LGD. It also indicated that it would consider study designs with some enrichment and, potentially, interim analysis
and approval to mitigate sample size. We will be working with FDA to finalize an extension of our current screening study to support
such an expanded dysplastic BE indication once FDA resumes Breakthrough Device meetings for IVDs, which are currently on hold as the
branch works to clear a Covid-19 pandemic related backlog. This study will be a substantial, capital-intensive, but potentially highly
rewarding undertaking. Although the study size is yet to be determined and will depend on negotiations with FDA, it will be in the thousands.</FONT></P>

EsoGuard clinical utility requires providing evidence that it has a meaningful impact on the clinical care of patients undergoing the
procedure. It does not require demonstrating the performance of the assay, <I>i.e.</I>, the negative and positive predictive values.
Our PMA trials are designed and powered to do so. Clinical utility studies need to demonstrate that patients with a positive EsoGuard
test undergoes confirmatory EGD which leads to a specific intervention, <I>e.g.</I>, implementation of an NDBE surveillance program or
ablation of dysplastic BE. Ideally, the near-term EGD rate of EsoGuard negative patients should be low. In other words, EsoGuard testing
should be able to successfully triage patient to EGD vs. no EGD and that there is an intervention in EGD positive patients, which would
not have happened if the patient had not been triaged by EsoGuard.</FONT></P>

EsoGuard&rsquo;s clinical utility is very important for a variety of purposes, including, importantly, for private payor payment and
coverage. Our recent advisor board meeting with medical directors of private insurers confirmed this. They strongly indicated that one
of the most important factors in their future decision to grant payment and coverage will be demonstrating that physicians order the
test and, when they do, that clinical utility can be demonstrated.</FONT></P>

utility studies are also important for general EsoGuard commercialization to physician who want to know that it can &ldquo;find disease&rdquo;.
A recent U.K. study from Dr. Fitzgerald&rsquo;s team is a good example. They published a large study of GERD patients in a primary care
setting who underwent screening with Cytosponge/TFF-3 and showed that they were able to identify patients with BE and the occasional
EAC. This was not a performance study with routine EGD so the authors could not say how many BE-EAC patients were missed, which was likely
non-trivial given the published data on suboptimal Cytosponge/TFF-3 performance. However, the study was useful in convincing U.K. authorities
to initiate mobile testing centers around the country.</FONT></P>

shortly will launch an EsoGuard Registry study as our primary study to demonstrate clinical utility. Every patient undergoing EsoCheck
testing will be asked to provide informed consent for us to collect limited post-procedural data from the patient&rsquo;s physician on
care received after EsoGuard testing, most importantly whether they underwent EGD and, if so, what the results showed.</FONT></P>

are also in discussions with a large academic medical center to initiate a clinical utility study in which investigators would use the
network-wide electronic medical record to systematically identify at-risk GERD patients, offer them EsoGuard testing and compare them
to historical controls also identified from the database. The study would seek to demonstrate that an EsoGuard-guided strategy identifies
more BE-EAC patient than historical practice.</FONT></P>

we are helping investigators at a VA medical center launch a Department of Defense supported study to compare the positive predictive
value of EsoGuard followed by EGD compared to EGD alone and the relative costs of each strategy. The study would seek to demonstrate
that EsoGuard increases the positive rate of EGD, an important measure of the clinical utility of a noninvasive diagnostic test.</FONT></P>

are exploring additional EsoCheck applications beyond our core focus of BE-EAC. The application with the greatest potential may be the
monitoring of patients with Eosinophilic Esophagitis (EoE). EoE is a rapidly emerging allergy-mediated inflammatory condition of the
esophagus similar to, and often associated with, inflammatory bowel disease (IBD). Although underappreciated by the medical community
and frequently confused with GERD, EoE has a prevalence comparable to IBD and exacts a significant burden on patients. It can lead to
swallowing difficulties, esophageal scarring, food impaction and pain. Current treatment includes oral steroids and an elimination diet.
Several anti-inflammatory biologics are being evaluated to treat EoE. Since inflammation can persist despite resolution of symptoms,
treatment courses can be very difficult and costly for patients, requiring multiple and frequent invasive endoscopies with biopsies.
To date, efforts to replace endoscopy with a noninvasive diagnostic device have proven unsuccessful.</FONT></P>

March 2020, we entered into a clinical trial research agreement with the University of Pennsylvania to perform a pilot study to assess
whether EsoCheck can detect the eosinophils characteristic of active EoE and potentially serve as a less-invasive, more efficient, and
cost-effective alternative to endoscopic biopsies in the management of EoE patients. The study, entitled &ldquo;<I>Pilot Study of EsoCheck
Compared to Biopsies and Brush Cytology During Endoscopy for Evaluation of Eosinophilic Esophagitis</I>&rdquo;, was led by Gary W. Falk,
M.D., an internationally renowned expert on esophageal disease with specific experience and expertise in the management of EoE. The study,
which has been completed, was a prospective cross-sectional pilot feasibility study of ten patients with suspected or established EoE
scheduled for a clinically indicated upper endoscopy. The patients underwent esophageal sampling using EsoCheck, with the sample sent
for traditional cytologic analysis, followed by EGD, including brushings and biopsies. The study results have yet to be published but
preliminary reports indicate that EsoCheck is able to detect a meaningful number of eosinophils in patients with active disease. We have
already initiated discussions with Dr. Falk to lead a larger multicenter follow-up study powered to document EsoCheck&rsquo;s sensitivity
and specificity in detecting active EoE, compared to EGD with brushings and biopsy.</FONT></P>

has been demonstrated to be highly accurate at detecting all conditions along the BE-EAC spectrum and the data from the Moinova, <I>et
al</I> indicated that it does so with comparable sensitivities across the spectrum (Moinova, <I>et al. Sci Transl Med.</I> 2018 Jan
17;10(424): eaao5848). This is consistent with the biologic theory that aberrant methylation is an early marker of metaplastic transformation
which persists but does not increase dramatically as the patient progresses along the BE-EAC spectrum. EsoGuard is not designed to discriminate
between NDBE and more advanced conditions.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Patients
with NDBE undergo surveillance EGD to identify dysplastic BE so the patient can undergo endoscopic esophageal ablation to cure the BE
and halt progression to EAC. This surveillance strategy is not optimal. It is clear that progression along the BE-EAC spectrum is not
necessarily linear. Patients do develop EAC between surveillance EGDs, often referred to as &ldquo;interval&rdquo; cancers. Purported
risk-stratification tools have not yet led to risk-based surveillance intervals. Even if we were able to identify patients at high risk
for progression, frequent surveillance EGDs are not necessarily palatable. EsoCheck would be an ideal tool to provide more frequent risk-based
surveillance if it could be paired with so-called progression markers capable of discriminating between NDBE and dysplastic BE, or at
least NDBE and HGD.</FONT></P>

submissions of claims until Medicare payment was effective. To facilitate this, on February 12, 2021, we entered into a Second Amendment
to the License Agreement with CWRU which extended the date of Milestone III, eliminated the Milestone III payment, and provided for an
equivalent amount paid by us to CWRU in connection with the execution of the amendment. Milestone III is awaiting formal GAAP revenue
recognition of initial out-of-network payments received from private payors and we expect to achieve this milestone shortly.</FONT></P>

the License Agreement, we are responsible for the costs incurred by CWRU in preparing, filing and prosecuting any patents related to
the EsoGuard and EsoCheck technology (subject to a provision for cost sharing in the event CWRU grants other non-overlapping licenses
to the technology), and agreed to reimburse CWRU for approximately $272,553 of such costs incurred by it prior to the date of the License
Agreement. Of such amount, $50,000 was paid at signing of the License Agreement, $50,000 is payable upon completion of a bona fide financing
with a third party for net proceeds of at least $500,000, and the balance is payable in quarterly installments of $50,000 thereafter.
PAVmed provided us with the initial $50,000 to reimburse CWRU (which amount is included in the $22.4 million owed to PAVmed that as of
June 1, 2021 was satisfied through the issuance of the Convertible Promissory Note to PAVmed). CWRU agreed to apply for patent coverage,
at our expense, in any country requested by us, to the extent such protection is reasonably attainable. CWRU also may apply for patent,
copyright or trademark rights to the EsoGuard and EsoCheck technology in other countries, at its option, and we will have no rights under
any the patents in such countries unless we reimburse CWRU for its expenses. In the event of any actual or threatened infringement of
any patent in the field of use covered by the License Agreement, we will have the first right to commence an action against the infringer.
We also will have the right to defend against any claims that the EsoGuard and EsoCheck technology infringes on the intellectual property
rights of a third party.</FONT></P>

government agency, whichever comes later. The EsoGuard patents begin to expire in August 2024. However, we are pursuing applications
of the clinical utility to extend the patent protection with more recently filed families of cases that have a twenty-year term and,
if issued, will expire in the mid to late 2030s. The EsoCheck patents, which are currently the last to expire, begin to expire in May
2035.</FONT></P>

defines an LDT as &ldquo;an IVD that is intended for clinical use and designed, manufactured and used within a single laboratory.&rdquo;
FDA has long maintained that it has clear regulatory authority over LDTs and has chosen to fully exercise its authority for certain classes
of &ldquo;single laboratory&rdquo; IVDs which would satisfy its definition of an LDT, such as direct-to-consumer tests that do not involve
a health care provider. FDA, however, has generally not enforced these regulatory requirements for most LDTs not in one of these classes
and has generally not required these LDTs to undergo FDA premarket review of analytical validity and clinical validity, as all other
IVDs must. For over a decade, FDA has expressed its concern about insufficient regulatory oversight over increasingly high-risk LDTs.
On multiple occasions from 2010 to 2020 it announced its intent to reconsider its long-standing policy of LDT enforcement discretion
with respect to LDTs but never acted on this intent, limiting its actions to hosting a public workshop to gather feedback from industry
stakeholders. publishing two draft guidance documents describing a proposed risk-based framework to LDTs, issuing a report citing evidence
for the need for additional regulation of LDTs, and issuing a Discussion Paper on LDTs. FDA never issued a final guidance document on
the regulation of LDTs and in 2020 the Department of Health and Human Services (HHS) announced that, effective immediately, it was rescinding
all guidance, compliance manuals, website statements, or other informal issuances concerning FDA premarket review of LDTs, and that FDA
may not require premarket review of LDTs absent a formal notice-and-comment rulemaking process.</FONT></P>

2020 HHS directive notwithstanding, the regulatory status for LDTs such as EsoGuard remains somewhat ambiguous and uncertain. The current
administration could rescind the HHS directive and allow FDA to return to its previous regime of enforcement discretion. The Verifying
Accurate Leading-edge IVCT Development (VALID) Act of 2020, which seeks to revamp the regulatory framework of diagnostic tests, including
LDTs, is expected to be reintroduced in 2021 and could radically alter the landscape for LDTs. FDA may also choose to modify its enforcement
discretion of elements of its &ldquo;single laboratory&rdquo; definition of LDTs which by strict interpretation would require the LDT
to have been &ldquo;designed&rdquo; at the &ldquo;single laboratory&rdquo; and not transferred from another research laboratory, as EsoGuard
was.</FONT></P>

general, the higher the classification, the greater the time and cost to obtain approval to market. There are no &ldquo;standardized&rdquo;
requirements for approval, even within each class. For example, FDA could grant 510(k) status, but require a human clinical trial, a
typical requirement of a PMA. They could also initially assign a device Class III status but end up clearing a device as a 510(k) device
if certain requirements are met. The range of the number and expense of the various requirements is significant. The quickest and least
expensive pathway would be 510(k) clearance with a review of existing bench and animal data. The longest and most expensive path would
be a PMA with extensive randomized human clinical trials. We cannot predict fully how FDA will classify our products, nor predict what
requirements will be placed upon us to obtain market clearance or approval, or even if they will clear or approve our products at all.</FONT></P>

request marketing authorization by means of a 510(k) clearance, we must submit a pre-market notification demonstrating that the proposed
device is substantially equivalent to another currently legally marketed medical device, has the same intended use, and is as safe and
effective as a currently legally marketed device and does not raise different questions of safety and effectiveness than does a currently
legally marketed device. 510(k) submissions generally include, among other things, a description of the device and its manufacturing,
device labeling, medical devices to which the device is substantially equivalent, safety and biocompatibility information, and the results
of performance testing. In some cases, a 510(k) submission must include data from human clinical studies. Marketing may commence only
when FDA issues a clearance letter finding substantial equivalence. After a device receives 510(k) clearance, any product modification
that could significantly affect the safety or effectiveness of the product, or that would constitute a significant change in intended
use, requires a new 510(k) clearance or, if the device would no longer be substantially equivalent, could require a <I>de novo </I>request
or PMA. In addition, any additional claims the Company wished to make at a later date may require a PMA. If FDA determines that the product
does not qualify for 510(k) clearance, they will issue a Not Substantially Equivalent letter, at which point the Company must submit
and FDA must approve a <I>de novo </I>request or PMA before marketing can begin.</FONT></P>

We, FDA, or the IRB at each institution at which a clinical trial is being conducted may suspend a clinical trial at any time for various

of medical devices are required to comply with FDA manufacturing requirements contained in FDA&rsquo;s current Good Manufacturing Practices
(cGMP) set forth in the quality system regulations promulgated under section 520 of the Food, Drug and Cosmetic Act. cGMP regulations
require, among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation.
Failure to comply with statutory and regulatory requirements subjects a manufacturer to possible legal or regulatory action, including
the seizure or recall of products, injunctions, consent decrees placing significant restrictions on or suspending manufacturing operations,
and civil and criminal penalties. Adverse experiences with the device must be reported to FDA and could result in the imposition of marketing
restrictions through labeling changes or in device withdrawal. Device clearances or approvals may be withdrawn if compliance with regulatory
requirements is not maintained or if problems concerning safety or efficacy of the product occur following the approval. We expect to
use contract manufacturers to manufacture our products for the foreseeable future we will therefore be dependent on their compliance
with these requirements to market our products. We work closely with our contract manufacturers to assure that our products are in strict
compliance with these regulations.</FONT></P>

For example, the State of New York&rsquo;s clinical laboratory regulations, which have received an exemption from CLIA, contain provisions

Federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving any remuneration
(including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, to induce or in return for purchasing, leasing,
ordering or arranging for or recommending the purchase, lease or order of any good, facility, item or service reimbursable, in whole
or in part, under Medicare, Medicaid or other federal healthcare programs. The term &ldquo;remuneration&rdquo; has been broadly interpreted
to include anything of value. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common
activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged
to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception
or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does
not make the conduct per se illegal under the Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a
case-by-case basis based on a cumulative review of all its facts and circumstances. Several courts have interpreted the statute&rsquo;s
intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare
covered business, the Anti-Kickback Statute has been violated.</FONT></P>

the intent standard under the Anti-Kickback Statute was amended by the Patient Protection and Affordable Care Act of 2010, as amended
by the Health Care and Education Reconciliation Act of 2010, collectively the Affordable Care Act, to a stricter standard such that a
person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed
a violation. In addition, the Affordable Care Act codified case law that a claim including items or services resulting from a violation
of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.</FONT></P>

for money or property presented to the U.S. government. The False Claims Act also applies to false submissions that cause the government
to be paid less than the amount to which it is entitled, such as a rebate. Intent to deceive is not required to establish liability under
the False Claims Act. Several pharmaceutical, device and other healthcare companies have been prosecuted under these laws for, among
other things, allegedly providing free product to customers with the expectation that the customers would bill federal programs for the

payment system reforms including a national pilot program on payment bundling to encourage hospitals, physicians and other providers
to improve the coordination, quality and efficiency of certain healthcare services through bundled payment models. In addition, other
legislative changes have been proposed and adopted since the PPACA was enacted. On August 2, 2011, President Obama signed into law the
Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress
proposals in spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for
the years 2013 through 2021, triggering the legislation&rsquo;s automatic reduction to several government programs. This includes reductions
to Medicare payments to providers of 2.0% per fiscal year, which went into effect on April 1, 2013, and will stay in effect through 2024
unless congressional action is taken. On January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which,
among other things, reduced Medicare payments to several providers, including hospitals, imaging centers and cancer treatment centers
and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. We
expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts
that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our products
or additional pricing pressure.</FONT></P>

Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical
Health Act (&ldquo;HIPAA&rdquo;) established comprehensive protection for the privacy and security of health information. The HIPAA standards
apply to three types of organizations, or &ldquo;Covered Entities&rdquo;: health plans, healthcare clearinghouses, and healthcare providers
that conduct certain healthcare transactions electronically. Covered Entities and their business associates must have in place administrative,
physical, and technical standards to guard against the misuse of individually identifiable health information. Some of our activities,
including at our Lucid Test Centers and within our clinical trials, involve interactions with patients and their health information which
implicate HIPAA. Our activities also involve us entering into specific kinds of relationships with Covered Entities and business associates
of Covered Entities, which also implicate HIPAA. Penalties for violations of HIPAA include civil money and criminal penalties.</FONT></P>

activities must also comply with other applicable privacy laws, which impose restrictions on the access, use and disclosure of personal
information. More state and international privacy laws are being adopted. Many state laws are not preempted by HIPAA because they are
more stringent or are broader in scope than HIPAA. Since 2020 we have also had to comply with the California Consumer Privacy Act of
2018, which protects personal information other than health information covered by HIPAA. In the E.U., the General Data Protection Regulation
(&ldquo;GDPR&rdquo;) took effect in May 2018 and imposes increasingly stringent data protection and privacy rules. All of these laws
may impact our business and may change periodically, which could have an effect on our business operations if compliance becomes substantially
costlier than under current requirements. Our failure to comply with these privacy laws or significant changes in the laws restricting
our ability to obtain stool, blood and other patient samples and associated patient information could significantly impact our business
and our future business plans.</FONT></P>

payments for laboratory tests referred by physicians who, personally or through a family member, have ownership interests in or compensation
arrangements with the testing laboratory. The Stark law contains a number of specific exceptions which, if met, permit physicians who
have ownership or compensation arrangements with a testing laboratory to make referrals to that laboratory and permit the laboratory
to submit claims for Medicare payments for laboratory tests performed pursuant to such referrals. We are subject to comparable state
laws, some of which apply to all payors regardless of source of payment, and do not contain identical exceptions to the Stark law.</FONT></P>

Willis, M.D.</I></B> a co-inventor of the technologies underlying our lead products, EsoGuard and EsoCheck, has served as to us since
our inception and will serve on new Scientific Advisory Board. Dr Willis is a board-certified pathologist with specialty expertise in
gastrointestinal pathology. Dr. Willis is currently the Vice Chair for Clinical Affairs and a Professor of Pathology at CWRU and University
Hospitals Cleveland Medical Center. As an expert in the pathology and molecular biology of gastrointestinal cancer, Dr. Willis has been
integral to the development of a large NIH-funded translational research program in gastrointestinal oncology at CWRU and University
Hospitals Cleveland Medical Center/NIH-funded Barrett&rsquo;s Esophagus Translational Network (BETRNet) that investigates the translational
application of genetics to gastrointestinal practice at CWRU and University Hospitals Cleveland Medical Center. Dr. Willis&rsquo; research
focuses on the identification of diverse molecular pathways in gastrointestinal cancer and of the applicability of these findings to
directly improve patient care. Dr. Willis recently initiated studies which define the presence of a unique subset of colon cancers in
African Americans linked to poor outcomes. Dr. Willis, working with Dr. Chak and Dr. Markowitz, identified methylation markers present
in precancerous lesions of the esophagus and developed the concept that these markers would be ideal as screening biomarkers. During
his career Dr Willis has been at the forefront of a number of pivotal discoveries in gastrointestinal oncology and has participated in
over 130 peer-reviewed publications.</FONT></P>

February 2019, PAVmed hired David F. Wurtman, M.D. as an at-will employee to serve as Executive Vice President of Strategic Projects
for PAVmed and Chief Medical Officer for Lucid. Dr. Wurtman devoted substantially all of his business time to our operations during the
fiscal year ended December 31, 2020. All of his cash compensation as an employee to date has been paid by PAVmed. In connection with
his employment by PAVmed, we granted to Dr. Wurtman options to purchase 300,000 shares of our common stock, at an exercise price of $1.00
per share. In addition, Dr. Wurtman received a separate grant of stock options to purchase 200,000 shares of our common stock, at an
exercise price of $1.00 per share, upon achievement of certain product development objectives established by our Board of Directors.
These stock options were granted under the Plan, have a term of 10 years and vest in 12 equal quarterly installments. In connection with
the grants to Dr. Wurtman, the Board of Directors waived the yearly award limit under the Plan. Prior to becoming an executive officer
of ours, Dr. Wurtman was party to a consulting agreement with us, which provided for him to act as a medical expert for us. Pursuant
to the consulting agreement, for the period from January 1, 2019 until his employment by PAVmed on February 18, 2019, Dr. Wurtman was
paid $49,720 in consulting fees by us.</FONT></P>

of the grant, owns common stock possessing more than 10% of the total combined voting power of all classes of our stock. The aggregate
fair market value of all shares of common stock with respect to which incentive stock options are exercisable by a participant for the

The notice must be accompanied by payment in full of the purchase price, either in cash or, if provided in the agreement, in our securities
or in combination of the two. The committee also may permit a holder to elect to pay the exercise price by irrevocably authorizing a
third party to sell the shares acquired upon exercise of the option and remit to us a sufficient portion of the sale proceeds to pay
the entire exercise price and any tax withholding resulting from such exercise. The committee also may permit a holder to pay the exercise
price pursuant to net exercise procedures.</FONT></P>

stock options granted under the Plan may not be transferred other than by will or by the laws of descent and distribution and all stock
options are exercisable, during the holder&rsquo;s lifetime, only by the holder or in the event of legal incapacity or incompetency,
the holder&rsquo;s guardian, or legal representative. However, a holder, with the approval of the Board of Directors, may transfer a
non-qualified stock option by gift or domestic relations order to a family member of the holder, or to an entity in which more than 50%
of the voting interests are owned by family members of the holder or the holder.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Generally,
if the holder is an employee, no stock options granted under the Plan may be exercised by the holder unless he or she is employed by
us or a subsidiary of ours at the time of the exercise and has been so employed continuously from the time the stock options were granted.
However, in the event the holder&rsquo;s employment is terminated due to disability, the holder may still exercise his or her vested
stock options for a period of 12 months, or such other greater or lesser period as the Board of Directors may determine from the date
of termination, or until the expiration of the stated term of the stock option, whichever period is shorter. Similarly, should a holder
die while employed by us or a subsidiary of ours, his or her legal representative or legatee under his or her will may exercise the decedent
holder&rsquo;s vested stock options for a period of 12 months, or such other greater or lesser period as the Board of Directors may determine,
from the date of his or her death, or until the expiration of the stated term of the stock option, whichever period is shorter. If the
holder&rsquo;s employment is terminated due to normal retirement, the holder may exercise his or her vested stock options for a period
of 12 months, or such other greater or lesser period as the Board of Directors may determine, from the date of termination, or until
the expiration of the stated term of the stock option, whichever period is shorter. If the holder&rsquo;s employment is terminated for
any reason other than death, disability or normal retirement, the stock option will automatically terminate, except that if the holder&rsquo;s
employment is terminated without cause, then the portion of any stock option that is vested on the date of termination may be exercised
for the lesser of three months, or such other greater or lesser period as the Board of Directors may determine, from the date of termination,
or until the expiration of the stated term of the stock option, whichever period is shorter.</FONT></P>

Appreciation Rights</I>. Subject to the terms and conditions of the Plan, the committee may grant stock appreciation rights in tandem
with an option or alone and unrelated to an option. Stock appreciation rights may be granted to participants who have been, or are being,
granted stock options under the Plan as a means of allowing the participants to exercise their stock options without the need to pay
the exercise price in cash. In conjunction with non-qualified stock options, stock appreciation rights may be granted either at or after
the time of the grant of the non-qualified stock options. In conjunction with incentive stock options, stock appreciation rights may
be granted only at the time of the grant of the incentive stock options. A stock appreciation right entitles the holder to receive a
number of shares of common stock having a fair market value (on the date of exercise) equal to the excess fair market value of one share
of common stock (on the date of exercise), over the exercise price of the related stock option, if granted in tandem with an option,
or over the fair market value of the common stock on the date of grant, if granted alone, multiplied by the number of shares subject
to the stock appreciation right. The granting of a stock appreciation right in tandem with an option will not affect the number of shares
of common stock available for awards under the Plan. The number of shares available for awards under the Plan will, however, be reduced
by the number of shares of common stock acquirable upon exercise of the option to which the stock appreciation right relates.</FONT></P>

if any to be paid for the restricted stock by the person receiving the stock from us, the time or times within which awards of restricted

the restricted stock will cause a forfeiture of the restricted stock and any retained distributions. Except for the foregoing restrictions,

our formation, we entered into the License Agreement with CWRU. Under the terms of the License Agreement, we acquired an exclusive worldwide
right to use the intellectual property rights to the EsoGuard technology for the detection of changes in the esophagus. As compensation
for the license, CWRU received equity in us as described elsewhere in this prospectus. In addition, CWRU is entitled to receive royalties
based on net sales by us of products utilizing the EsoGuard technology, as well as a specified portion of any other non-royalty proceeds
received by us pursuant to a sublicense of the EsoGuard technology (less any amounts distributed to CWRU as a stockholder of ours during

sale of a product utilizing the EsoGuard technology, with the minimum amount rising based on prior years&rsquo; net sales of the product.</FONT></P>

License Agreement is subject to certain regulatory and commercialization milestones, with a payment due from us to CWRU upon the achievement
of certain milestones. The Milestone I payment has been made &ndash; a $75,000 milestone payment upon FDA&rsquo;s clearance of EsoCheck.
With regard to Milestone II, first commercial sale of a licensed product, in February 2021, we entered into a Second Amendment to the
License Agreement with CWRU which extended the date of Milestone III, eliminated the $100,000 Milestone III payment, and provided for
an equivalent amount paid by us to CWRU in connection with execution of the amendment. The license agreement provides for one additional
milestone payment &ndash; a $200,000 milestone payment due upon a PMA submission to FDA related to a licensed product.</FONT></P>

technology (subject to a provision for cost sharing in the event CWRU grants other non-overlapping licenses to the technology), and agreed

    entered into a management services agreement with PAVmed. Under the agreement, PAVmed provides certain management services to us
    for which we pay a monthly fee. The fee was $20,000 per month from May 15, 2018 to February 15, 2019, increased to $60,000 per month
    upon effective February 16, 2019 through June 4, 2019; increased to $90,000 on June 5, 2019; increased to $190,000 per month on July
    1, 2020, and increased to $290,000 per month on February 1, 2021. The periodic increases are directly related to the incremental
    amount of PAVmed resources dedicated to Lucid activities and over time the business focus and consequently the type of costs incurred
    changed from engineering and product development to clinical trial efforts and commercial activities. We also reimburse PAVmed for
    all reasonable out-of-pocket expenses incurred by it in connection with the performance of the management services, including a portion
    of its shared administrative, facility cost, insurances and other corporate overhead incurred by PAVmed on our behalf. The management
    services include management and oversight of our activities relating to research and development for our EsoGuard/EsoCheck product;
    regulatory matters concerning our EsoGuard/EsoCheck product; manufacturing, marketing, and commercialization of our EsoGuard/EsoCheck
    product; financial and accounting matters; and legal matters. As of the date of this prospectus, we have accrued an aggregate of
    approximately $22.4 million to PAVmed pursuant to this agreement. The amount that we pay to PAVmed under the management services
    agreement also reflects an unspecified portion of the compensation to the executive officers and employees it makes available to
    us. Upon the closing of this offering, certain team members, including most of our sales operations, shall become direct employees
    of ours, and a portion of the compensation of our other executive officers shall be paid directly by us. As a result, the
    management services agreement will be amended to reduce the monthly fee to $260,000. The term of the management services agreement
    continues until such time as our Board of Directors determines. We expect to continue to use PAVmed&rsquo;s services under the management
    services agreement until such time as our Board of Directors determines it would be in our best interest to engage a dedicated management

    compensation under each such consulting agreement included: the grant of stock options under the Plan to each individual to purchase

without a meeting and without prior notice to other stockholders. As a result, PAVmed&rsquo;s controlling interest may discourage a change

any such transaction without the approval of the audit committee. The audit committee will consider all relevant factors when determining
whether to approve a related party transaction, including whether the related party transaction is on terms no less favorable than terms
generally available to an unaffiliated third-party under the same or similar circumstances and the extent of the related party&rsquo;s
interest in the transaction.</FONT></P>

stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an &ldquo;interested stockholder&rdquo;

status did own, 15% or more of a corporation&rsquo;s voting stock. Generally, a &ldquo;business combination&rdquo; includes a merger,
asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision

in its certificate of incorporation or by-laws resulting from a stockholders&rsquo; amendment approved by at least a majority of the
outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts

short sales are sales made in an amount not greater than the underwriters&rsquo; option to purchase additional shares of our common stock
in this offering. The underwriters may close out any covered short position by either exercising their option to purchase additional
shares of our common stock or purchasing shares of our common stock in the open market. In determining the source of shares to close
out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the
open market as compared to the price at which they may purchase shares through the option to purchase additional shares.</FONT></P>

short sales are sales in excess of the option to purchase additional shares of our common stock. The underwriters must close out any
naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters
are concerned that there may be downward pressure on the price of the shares of our common stock in the open market after pricing that
could adversely affect investors who purchase in this offering.</FONT></P>

stabilizing bid is a bid for the purchase of shares of common stock on behalf of the underwriters for the purpose of fixing or maintaining
the price of the common stock. A syndicate covering transaction is the bid for or the purchase of shares of common stock on behalf of
the underwriters to reduce a short position incurred by the underwriters in connection with the offering. Similar to other purchase transactions,
the underwriters&rsquo; purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of
our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock

and commercialization of products and services. In this regard, in 2019, the Company recognized a $75,000 research and development expense
in connection with a regulatory clearance milestone, which was paid in 2019. The CWRU License Agreement was amended to: change the achievement
date of commercialization milestone from November 2020 to August 2021; to eliminate the payment with respect to the commercialization
milestone; and to add a non-refundable payment to CWRU in consideration for such changes to the commercialization milestone (&ldquo;CWRU
License Agreement Amendment Fee&rdquo;). In connection with such CWRU License Agreement Amendment, the Company recognized $100,000 of
general and administrative expense, with such expense included in accrued expenses as of December 31, 2020, and paid-in-full in February
2021.</FONT></P>

public offering (&ldquo;IPO&rdquo;) of Lucid Diagnostics Inc. common stock (&ldquo;IPO scenario&rdquo;); and, to continue as a private
company (&ldquo;stay private scenario&rdquo;). With respect to the IPO scenario, the valuation of the Lucid Diagnostics Inc. common stock
was computed using assumptions, including dates of the IPO, to calculate an estimated pre-money valuation; and, with respect to the stay
private scenario, an income approach was used, wherein a risk-adjusted discount rate is applied to projected future cash flows. A relative
weighting of 75% was applied to the IPO scenario and 25% was assigned to the stay private scenario.</FONT></P>

weighted-average number of shares of common stock outstanding for the three months ended March 31, 2021 and 2020 include the shares of
the Company issued and outstanding during such periods, each on a weighted average basis. The basic weighted average number of shares
common stock outstanding excludes common stock equivalent incremental shares, while diluted weighted average number of shares outstanding
includes such incremental shares. However, as the Company was in a loss position for all periods presented, basic and diluted weighted
average shares outstanding are the same, as the inclusion of the incremental shares would be anti-dilutive. In this regard, a total of
2,031,667 and 991,667 stock options and restricted stock awards, as granted under the Lucid Diagnostics Inc. 2018 Equity Plan, were outstanding
as of March 31, 2021 and 2020, respectively, have been excluded from the computation of diluted weighted average shares outstanding as
their inclusion would be anti-dilutive.</FONT></P>

ability to continue as a going concern within one year of the date of the financial statements are issued. In each reporting period (including
interim periods), an entity is required to assess conditions known and reasonably knowable as of the financial statement issuance date
to determine whether it is probable an entity will not meet its financial obligations within one year from the financial statement issuance
date. Under the provisions of ASC 205-40, substantial doubt about an entity&rsquo;s ability to continue as a going concern exists

preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (&ldquo;U.S.
GAAP&rdquo;) requires management to make accounting estimates and assumptions that affect the reported amounts of assets and liabilities
and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during
the reporting period. Significant estimates in these consolidated financial statements include those related to the fair value of debt
obligations and common stock purchase warrants. Additional significant estimates include the provision or benefit for income taxes and
the corresponding valuation allowance on deferred tax assets. On an ongoing basis, the Company evaluates its estimates, judgements, and
methodologies. The Company bases its estimates on historical experience and on various other assumptions believed to be reasonable. Due
to the inherent uncertainty involved in making such judgements, assumptions, and accounting estimates, the actual financial statement
results could differ materially from such accounting estimates and assumptions.</FONT></P>

costs consist of certain legal, accounting, and other advisory fees incurred related to the Company&rsquo;s efforts to raise debt and

to the extent the underlying security is equity classified or a current period expense to extent the underlying security is liability
classified or for which the fair value option is elected. Offering costs, lender fees, and warrants issued in connection with debt financing,
to the extent the fair value option is not elected, are recognized as debt discount, which reduces the reported carrying value of the
debt, with the debt discount amortized as interest expense, generally over the contractual term of the debt agreement, to result in a
constant rate of interest. Offering costs associated with in-process capital financing are accounted for as deferred offering costs.

warrant agreement, and are generally classified as equity, but may be classified as a derivative liability if the warrant agreement provides
required or potential full or partial cash settlement. A warrant classified as a derivative liability, or a bifurcated embedded conversion

adjusted at each reporting period, with the resulting fair value adjustment recognized as other income or expense. If upon the occurrence

Deferred tax assets and deferred tax liabilities are recognized for estimated future tax consequences attributable to differences between

loss and tax credit carryforwards. Deferred tax assets and deferred tax liabilities are measured using enacted tax rates expected to

of January 1, 2020, the Company adopted the guidance of ASU 2017-11, issued by the FASB in July 2017, <I>Earnings Per Share (Topic 260),
Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815) - Part I - Accounting for Certain Financial Instruments
with Down-Round Features, and Part II - Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain
Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. </I>Principally, ASU 2017-11 amendments
simplify the accounting for certain financial instruments with down-round features. The amendments require companies to disregard the
down-round feature when assessing whether the instrument is indexed to its own stock, for purposes of determining liability or equity
classification. Companies that provide earnings per share data will adjust their basic earnings per share calculation for the effect
of the down-round feature when triggered (i.e., when the exercise price of the related equity-linked financial instrument is adjusted
downward because of the down-round feature) and will also recognize the effect of the trigger within equity. Additionally, ASU 2017-11
also addresses &ldquo;navigational concerns&rdquo; within the FASB ASC related to an indefinite deferral available to private companies
with mandatorily redeemable financial instruments and certain noncontrolling interests, which has resulted in the existence of significant
&ldquo;pending content&rdquo; in the ASC. The FASB decided to reclassify the indefinite deferral as a scope exception, which does not
have an accounting effect. The guidance of ASU 2017-11 is effective for public business entities, as defined in the ASC Master Glossary,
for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. With respect to all other entities,
including the Company under its JOBS Act EGC Accounting Election, as discussed above, the guidance of ASU 2017-11 was effective for fiscal
years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. The adoption of the
ASU 2017-11 guidance as of January 1, 2020 did not have an effect on the Company&rsquo;s financial statements.</FONT></P>

December 2019, the FASB issued ASU No. 2019-12, <I>&ldquo;Income Taxes: Simplifying the Accounting for Income Taxes&rdquo;,</I> (&ldquo;ASU

allocation, and calculating income taxes in interim periods, and adds revised guidance to reduce complexity in certain areas, including
recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. Adoption of the guidance of ASU
2019-12 is required for annual and interim financial statements beginning after December 15, 2020. The Company&rsquo;s adoption of the

required by FASB ASC Topic 740, <I>Income Taxes,</I> (&ldquo;ASC 740), a &ldquo;more-likely-than-not&rdquo; criterion is applied when
assessing the estimated realization of deferred tax assets through their utilization to reduce future taxable income, or with respect
to a deferred tax asset for tax credit carryforward, to reduce future tax expense. A valuation allowance is established, when necessary,
to reduce deferred tax assets, net of deferred tax liabilities, when the assessment indicates it is more-likely-than-not, the full or
partial amount of the net deferred tax asset will not be realized. Accordingly, the Company evaluated the positive and negative evidence
bearing upon the estimated realizability of the net deferred tax assets, and based on the Company&rsquo;s history of operating losses,
concluded it is more-likely-than-not the deferred tax assets will not be realized, and therefore recognized a valuation allowance reserve
equal to the full amount of the deferred tax assets, net of deferred tax liabilities, as of December 31, 2020 and 2019.</FONT></P>

other provisions, the CARES Act increases the limitation on the allowed business interest expense deduction from 30 percent to 50 percent
of adjusted taxable income for tax years beginning January 1, 2019 and 2020 and allows businesses to immediately expense the full cost
of Qualified Improvement Property, retroactive to tax years beginning on or after January 1, 2018. Additionally, the CARES Act permits
net operating loss carryovers (&ldquo;NOLs&rdquo;) and carrybacks to offset 100% of taxable income for taxable years beginning before
2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable
years to generate a refund of previously paid income taxes. While the Company is currently evaluating the impact of these CARES Act provisions,
it is not expected, at this time, to have a material impact on the income tax provision.</FONT></P>

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication
of such issue.</FONT></P>
