 CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

 This Report, including all documents incorporated
by reference herein, includes certain statements constituting "forward-looking" statements within the meaning of Section 27A
of the Securities Act, Section 21E of the Exchange Act and the Private Securities Litigation Reform Act of 1995, including statements
concerning our beliefs, plans, objectives, goals, expectations, anticipations, estimates, intentions, operations, future results and prospects,
and we rely on the "safe harbor" provisions in those laws. We are including this statement for the express purpose of availing
ourselves of the protections of such safe harbors with respect to all such forward-looking statements. The forward-looking statements
in this report reflect our current views with respect to future events and financial performance. In this report, the words "anticipates,"
"believes," "expects," "intends," "future," "estimates," "may,"
"could," "should," "would," "will," "shall," "propose," "continue,"
"predict," "plan" and similar expressions are generally intended to identify certain of the forward-looking statements.
Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date made. Any forward-looking
statement is not a guarantee of future performance.

 These forward-looking statements are subject to
certain risks and uncertainties, and actual results may differ materially from those in the forward-looking statements as a result of
various factors, including, but not limited to those items shown under "Item 1A. Risk Factors" and "Item 7 – Management's
Discussion and Analysis of Financial Condition and Results of Operations" included in Part II. You should read this report completely
with the understanding that our actual results may differ materially from what we expect. Unless required by law, we undertake no obligation
to publicly disclose the result of any revision of these forward-looking statements to reflect events or circumstances after the date
they are made or to reflect the occurrence of unanticipated events.

 You should not place undue reliance on these types
of forward-looking statements, which speak only as of the date that they were made. These forward-looking statements are based on the
beliefs and assumptions of the Company's management based on information currently available to management and should be considered
in connection with any written or oral forward-looking statements that the Company may issue in the future as well as other cautionary
statements the Company has made and may make. Except as required by law, the Company does not undertake any obligation to release publicly
any revisions to these forward-looking statements after completion of the filing of this Report to reflect later events or circumstances
or the occurrence of unanticipated events.

 RISK FACTOR SUMMARY

 Below is a summary of material factors that make
an investment in our common stock speculative or risky. Importantly, this summary does not address all of the risks and uncertainties
that we face. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider
this section to be a complete discussion of all potential risks or uncertainties that may substantially impact our business. Additional
discussion of the risks and uncertainties summarized in this risk factor summary, as well as other risks and uncertainties that we face,
can be found under "Risk Factors" in Part I, Item 1A of this Report. Moreover, we operate in a competitive and rapidly changing
environment. New factors emerge from time to time, and it is not possible to predict the impact of all of these factors on our business,
financial condition or results of operations. The below summary is qualified in its entirety by that more complete discussion of such
risks and uncertainties. You should consider carefully the risks and uncertainties described under "Risk Factors" in Part
I, Item 1A of this Report as part of your evaluation of an investment in our common stock.

 Risks Related to Our Operations

 While
the Company's financial statements have been prepared on a going concern basis, we do not currently have sufficient working capital
to fund our existing liabilities and planned operations for the next twelve months and we may be required to cease our operations altogether
if we are unable to secure sufficient funding.

 We
currently do not have sufficient capital to pay all amounts owed under our License Agreement with Case Western Reserve University ("CWRU")
in the amount of approximately $407,000 as of December 31, 2023 and on March 22, 2024, we received a notice of termination from CWRU.

 We
may not successfully identify new product candidates to expand our development pipeline.

 If
we are able to raise sufficient capital, we expect that we will incur significant losses over the next several years and may never achieve
or maintain profitability.

 Our
development efforts have historically been with product candidates in preclinical development.

 Our
short operating history may make it difficult to evaluate the success of our business to date and to assess our future viability.

 The
Company and its subsidiaries have limited insurance for their operations and are subject to various risks of loss.

 Drug
development involves a lengthy and expensive process with an uncertain outcome, including failure to demonstrate safety and efficacy
to the satisfaction of the FDA or similar regulatory authorities outside the United States. We may incur additional costs or experience
delays in completing, or ultimately be unable to complete, the product manufacturing of any product candidates.

 If
serious adverse events or unacceptable side effects are identified during the development of any product candidates, we may need to abandon
or limit our development of these product candidates.

 If
we fail to establish and maintain proper and effective internal control over financial reporting, our operating results and our ability
to operate our business could be harmed.

 Risks Related to Our Financial Position and Need for Additional
Capital

 We need substantial additional funding. If we
are unable to secure sufficient capital in the near term, we may be required to further reduce or eliminate product development and potentially
cease operations.

 Raising capital will cause dilution to our stockholders,
restrict our operations, or require us to relinquish rights to our technologies or product candidates.

 Risks Related to the Commercialization of Any
Product Candidate

 We face substantial competition, which may result
in others discovering, developing or commercializing competing products before or more successfully than we do.

 Product liability lawsuits against us could cause
us to incur substantial liabilities and to limit commercialization of any products that we may develop.

 Risks Related to Our Dependence on Third Parties

 Future development collaborations may be important
to us. If we are unable to enter into or maintain these collaborations, or if these collaborations are not successful, our business could
be adversely affected.

 We may contract with third parties for the manufacture
of product candidates for preclinical and clinical studies and may expect to continue to do so for commercialization. This potential reliance
on third parties increases the risk that we will not have sufficient quantities of product candidates or products at an acceptable cost
and quality, which could delay, prevent or impair our development or commercialization efforts.

 Data provided by collaborators and other parties
upon which we rely has not been independently verified and could turn out to be inaccurate, misleading, or incomplete.

 Risks Related to Intellectual Property

 If we are unable to obtain and maintain intellectual
property protection for technology and products we plan to develop or if the scope of the intellectual property protection obtained is
not sufficiently broad, our competitors could develop and commercialize technology and products similar or identical to ours, and our
ability to successfully commercialize our technology and products may be impaired.

 If we fail to comply with our obligations under
any license agreement or other agreements under which we may license intellectual property and other rights from third parties or otherwise
experience disruptions to our business relationships with our future licensors, we could lose those rights or other rights, which could
be the products upon which our business depends.

 We may become involved in lawsuits to protect
or enforce our patents or other intellectual property, which could be expensive, time consuming and unsuccessful.

 We may need to license certain intellectual property
from third parties, and such licenses may not be available or may not be available on commercially reasonable terms.

 Third parties may initiate legal proceedings
alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a material
adverse effect on the success of our business.

 If we are unable to protect the confidentiality
of our trade secrets, our business and competitive position would be harmed.

 Risks Related to Our Employee Matters, Managing
Growth and Macroeconomic Conditions

 Our future success depends on our ability to
attract, hire, retain and motivate executives, key employees, and our general workforce.

 We expect to expand our research and development
function, as well as our corporate operations, and as a result, we may encounter difficulties in managing our growth, which could disrupt
our operations.

 We may face risks related to securities litigation
that could result in significant legal expenses and settlement or damage awards.

 Risks Related to Our Common Stock

 There is a substantial lack of liquidity of our
common stock and volatility risks, and because there is no active public trading market for our common stock, you may not be able to resell
your common stock.

 The market for our common stock is subject to
rules relating to low-priced stock ("Penny Stock") which may limit our ability to raise capital.

 Future sales of shares by existing stockholders
could cause the Company's stock price to decline.

 We expect our stock price to be volatile, and
the market price of our common stock may drop unexpectedly.

 We may issue preferred stock, and the terms of
such preferred stock may reduce the value of our common stock.

 Our executive officers, directors and principal
stockholders, if they choose to act together, will have the ability to control all matters submitted to stockholders for approval.

 Our amended and restated certificate of incorporation
and amended and restated bylaws provides that state or federal court located within the state of Delaware will be the sole and exclusive
forum for substantially all disputes between us and our stockholders, which could limit its stockholders' ability to obtain a favorable
judicial forum for disputes with us or our directors, officers or other employees.

 Anti-takeover provisions contained in our amended
and restated certificate of incorporation and amended and restated bylaws, as well as provisions of Delaware law, could impair a takeover
attempt.

 ITEM 1.

 BUSINESS

 Business
Overview

 We are a development-stage biotechnology company
focused on advancing and eventually commercializing immunotherapies for the treatment of cancer. We have historically advanced an early-stage
product candidate, MIE-101, that is based on a naturally occurring plant virus licensed from Case Western Reserve University ("CWRU")
(see Note 12 to the accompanying consolidated financial statements). In addition, we are pursuing new product candidates and platforms
to expand our pipeline based on a deep understanding of immunotherapies, although we may be unsuccessful in our efforts to identify new
product candidates.

 Business Strategy

 Our strategy is to leverage our considerable industry
experience, understanding of immunotherapies, and development expertise to identify, develop and commercialize product candidates with
significant market potential that can fulfill unmet medical needs in the treatment of cancer. We have assembled a management team along
with both scientific and business advisors, including recognized experts in the field of immunotherapy, with significant industry and
regulatory experience to lead and execute the development and commercialization of immunotherapy products. We are focused on identifying
and successfully licensing or acquiring new product candidates.

 Our Corporate History and Background

 Private Mosaic, a Delaware corporation, was formed
on March 30, 2020. On July 1, 2020, we signed a Material Transfer, Evaluation, and Exclusive Option Agreement ("License Option Agreement")
with Case Western Reserve University ("CWRU"), granting us the exclusive right to license the cowpea mosaic virus ("CPMV")
platform technology to treat and prevent cancer and infectious diseases in humans and for veterinary use. On May 4, 2022, we entered into
the license agreement with CWRU ("License Agreement") pursuant to our rights granted under the License Option Agreement (see
Note 6 to the accompanying audited consolidated financial statements). On March 22, 2024, we received a notice of termination from CWRU
(see Note 12 to the accompanying consolidated financial statements). On August 19, 2020, Patriot Scientific Corporation (now known as
Mosaic ImmunoEngineering, Inc.) and Private Mosaic entered into a reverse merger transaction, as further described below.

 Reverse Merger

 On August 19, 2020, Patriot Scientific Corporation,
a corporation organized under Delaware law on March 24, 1992 (now known as Mosaic ImmunoEngineering, Inc.) and Private Mosaic entered
into a stock purchase agreement ("Stock Purchase Agreement"), whereby one of the wholly owned subsidiaries of Patriot Scientific
Corporation ("PTSC") merged with and into Private Mosaic, with Private Mosaic surviving as wholly owned subsidiary of PTSC
(the "Reverse Merger"). The transaction closed on August 21, 2020 ("Closing Date") in accordance with the terms
of the Stock Purchase Agreement.

 On the Closing Date, Patriot Scientific Corporation
acquired 100% of the issued and outstanding common stock of Private Mosaic, representing 630,000 shares of its Class A common stock ("Class
A Stock") and 70,000 shares of its Class B common stock ("Class B Stock") (collectively referred to as "Target
Common Stock"). In exchange for the Target Common Stock, the holders of the Class A Stock received 630,000 shares of the Company's
Series A Convertible Voting Preferred Stock ("Series A Preferred") and holders of the Class B Stock received 70,000 shares
of the Company's Series B Convertible Voting Preferred Stock ("Series B Preferred"). Each share of Series A Preferred
converted into 10.194106 shares of common stock as defined in the Series A Certificate of Designation. Each share of Series B Preferred
converts into 11.46837 shares of common stock of the Company, possesses full voting rights, on an as-converted basis, as the common stock
of the Company and contains certain anti-dilution rights, as defined in the Series B Certificate of Designation. On a fully diluted, as
converted basis, the holders of Series A Preferred and Series B Preferred, in aggregate, owned 90% of the issued and outstanding common
stock of the Company as of the Closing Date.

 The Reverse Merger was treated by the Company
as a reverse merger in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP").
For accounting purposes, Private Mosaic was considered to have acquired PTSC as the accounting acquirer because: (i) Private Mosaic
stockholders owned 90% of the combined company, on an as-converted basis, immediately following the Closing Date, (ii) Private Mosaic
directors held a majority of board seats in the combined company and (iii) Private Mosaic management held all key positions in the
management of the combined company. Accordingly, Private Mosaic's historical results of operations replaced PTSC's historical
results of operations for all periods prior to the Closing Date of the Reverse Merger and, for all periods following the Closing Date
of the Reverse Merger, the results of operations of the combined company are included in the Company's financial statements.

 Other Key Corporate Events

 On November 30, 2020, we filed amended and restated
articles of incorporation with the Secretary of State of the State of Delaware ("Amended and Restated Certificate") to change
the name of the Company to Mosaic ImmunoEngineering, Inc. ("Name Change") to align the Company's corporate name with
its new strategic direction, to implement a 1-for-500 reverse stock split ("Reverse Stock Split"), and to reduce the number
of authorized shares of common stock from 600 million to 100 million. The Reverse Stock Split was effective on December 2, 2020. All share
numbers and preferred stock conversion numbers included herein have been retroactively adjusted to reflect the 1-for-500 Reverse Stock
Split. On December 30, 2020, we changed our fiscal year end from May 31 to December 31.

 Our funding has primarily come from the issuance
of convertible notes. On May 7, 2021 and February 18, 2022, we issued unsecured convertible promissory notes in the aggregate principal
amount of $575,000 and $341,632, respectively (see Note 7 to the accompanying consolidated financial statements).

 On July 6, 2022, we entered into a redemption
agreement (the "Redemption Agreement") with Holocom, Inc. ("Holocom") pursuant to which we requested full redemption
of our 2,100,000 shares of Series A Preferred Stock at a redemption price of $0.40 per share, provided Holocom has sufficient capital
to redeem the underlying shares. During the year ended December 31, 2023 and 2022, we received cash proceeds in the amount of $433,000
and $343,000, respectively, upon the redemption of 1,242,500 and 857,500 shares of Series A Preferred Stock, respectively (see Note 4
to the accompanying consolidated financial statements).

 Patents and Proprietary Rights

 Our patent strategy is to in-license and/or file
patent applications on innovations and improvements to cover a significant majority of the major pharmaceutical markets in the world.
Generally, assuming all maintenance fees (annuities) are paid, patents have a term of twenty years from the earliest priority date (other
than a priority date for a provisional application). In some instances, patent terms can be increased or decreased, depending on the laws
and regulations of the country or jurisdiction that issued the patent. Notwithstanding the foregoing, the patent position of biotechnology
and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has in recent years been
the subject of much litigation. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of
the United States. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications
in the United States and other jurisdictions are typically not published until 18 months after filing, or in limited cases not at all.
Therefore, we cannot know with certainty whether we were the first to make the inventions claimed in our owned or licensed patents or
pending patent applications, or that we were the first to file for patent protection of such inventions. Also, examinations are often
lengthy and can involve numerous challenges to the claims sought. As a result, the issuance, scope, validity, enforceability and commercial
value of our patent rights are highly uncertain. Pending and future patent applications may not result in patents being issued which protect
our technology or products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and
products. Changes in either the patent laws or interpretation of the patent laws in the United States, the European Union, and other countries
may diminish the value of the underlying patents under our License Agreement or narrow the scope of our patent protection.

 Our success depends in large part on our ability
to obtain and maintain patent protection in the United States, the European Union, and other major pharmaceutical markets with respect
to any new proprietary technology or product candidates.

 In addition, the patent prosecution process is
expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable
cost or in a timely manner. We may choose not to seek patent protection for certain innovations and may choose not to pursue patent protection
in certain jurisdictions, and under the laws of certain jurisdictions, patents or other intellectual property rights may be unavailable
or limited in scope. Moreover, in some circumstances, we may not have the right to control the preparation, filing and prosecution of
patent applications, or to maintain the patents covering technology under a license agreement. Therefore, these patents and applications
may not be prosecuted and enforced in a manner consistent with the best interests of our business. Any inability by us or any future licensor
to protect adequately the underlying intellectual property may have a material adverse effect on our business, operating results, and
financial position.

 Our Trade Secrets

 We also rely upon unpatented trade secrets, and
there is no assurance that others will not independently develop substantially equivalent proprietary information and techniques or otherwise
gain access to our trade secrets or disclose such technology, or that such rights can be meaningfully protected. We require our employees,
consultants, outside scientific collaborators, and other advisers to execute confidentiality agreements upon the commencement of employment
or consulting relationships with us. These agreements provide that all confidential information developed or made known to the individual
during the course of the individual's relationship with us is to be kept confidential and not disclosed to third parties except in specific
circumstances. In the case of our employees, the agreement provides that all inventions conceived by such employees shall be our exclusive
property. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for our trade
secrets in the event of unauthorized use or disclosure of such information.

 Third-Party Rights

 Our success also depends in part on our ability
to gain access to third-party patent and proprietary rights and to operate our business without infringing on third-party patent rights.
We may be required to obtain licenses to patents or other proprietary rights from third parties to develop, manufacture and commercialize
product candidates. Licenses required under third-party patents or proprietary rights may not be available on terms acceptable to us,
if at all. If we do not obtain the required licenses, we could encounter delays in product development while we attempt to redesign products
or methods or we could be unable to develop, manufacture or sell products, if approved, requiring these licenses at all. The failure to
obtain licenses, if needed, may have a material adverse effect on our business, operating results, and financial position.

 Government
Regulation

 Regulatory Compliance

 Our planned research and development activities,
including testing in laboratory animals and in humans, our manufacture of product candidates, and oversight of suppliers and contract
manufacturers involved in the production of product candidates, as well as the design, manufacturing, safety, efficacy, handling, labeling,
storage, record-keeping, advertising, promotion and marketing of these product candidates that we may develop, are all subject to stringent
regulation, primarily by the FDA in the United States under the Federal Food, Drug, and Cosmetic Act (the "FDCA") and its implementing
regulations, and the Public Health Service Act ("PHS Act") and its implementing regulations, and by comparable authorities under
similar laws and regulations in other countries. If for any reason we do not comply with applicable requirements, such noncompliance can
result in various adverse consequences, including one or more delays in approval of, or even the refusal to approve, product licenses
or other applications, the suspension or termination of clinical investigations, the revocation of approvals if granted, as well as fines,
criminal prosecution, recall or seizure of products, injunctions against shipping products and total or partial suspension of production
and/or refusal to allow us to enter into governmental supply contracts.

 Product Development and Approval Process

 In the United States, product candidates we plan
to develop are regulated as biologic pharmaceuticals, or biologics. The FDA's regulatory authority for the approval of biologics resides
in the PHS Act. However, biologics are also subject to regulation under the FDCA because most biological products also meet the FDCA's
definition of "drugs." Most pharmaceuticals or "conventional drugs" consist of pure chemical substances and their
structures are known. Most biologics, however, are complex mixtures that are not easily identified or characterized. Biological products
differ from conventional drugs in that they tend to be heat-sensitive and susceptible to microbial contamination, thus requiring sterile
manufacturing processes. The process required by the FDA before biologic product candidates may be marketed in the United States generally
involves the following:

 completion of preclinical laboratory tests and
animal studies performed in accordance with the FDA's current Good Laboratory Practices regulations;

 submission to the FDA of an IND which must become
effective before human clinical trials may begin and must be updated annually;

 approval by an independent Institutional Review
Board ("IRB") ethics committee at each clinical site before the trial is initiated;

 performance of adequate and well-controlled clinical
trials to establish the safety, purity and potency of the proposed biologic, and its safety and efficacy for each indication;

 preparation of and submission to the FDA of a
Biologics License Application ("BLA") for a new biologic, after completion of all pivotal clinical trials;

 satisfactory completion of an FDA Advisory Committee
review, if applicable;

 a determination by the FDA within 60 days of
its receipt of a BLA to file the application for review;

 satisfactory completion of an FDA pre-approval
inspection of the manufacturing facilities to assess compliance with current Good Manufacturing Practice ("cGMP") regulations; and

 FDA review and approval of a BLA for a new biologic,
prior to any commercial marketing or sale of the product in the United States.

 Preclinical tests assess the potential safety
and efficacy of a product candidate in animal models. Clinical trials involve the administration of the investigational product to human
subjects under the supervision of qualified investigators in accordance with current Good Clinical Practices ("cGCPs"), which
include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. A protocol
for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. Additionally, approval
must also be obtained from each clinical trial site's IRB before the trials may be initiated, and the IRB must monitor the study
until completed. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public registries.

 The clinical investigation of a pharmaceutical,
including a biologic, is generally divided into three phases followed by potential post-market obligations. Although the phases are usually
conducted sequentially, they may overlap or be combined.

 Phase I studies are designed to evaluate the
safety, dosage tolerance, metabolism and pharmacologic actions of the investigational product in humans, the side effects associated with
increasing doses, and if possible, to gain early evidence on effectiveness.

 Phase II includes controlled clinical trials
conducted to preliminarily or further evaluate the effectiveness of the investigational product for a particular indication(s) in patients
with the disease or condition under study, to determine dosage tolerance and optimal dosage, and to identify possible adverse side effects
and safety risks associated with the product.

 Phase III clinical trials are generally controlled
clinical trials conducted in an expanded patient population generally at geographically dispersed clinical trial sites, and are intended
to further evaluate dosage, clinical effectiveness and safety, to establish the overall benefit-risk relationship of the investigational
product, and to provide an adequate basis for product approval.

 Phase IV clinical trials may be required to as
post-marketing studies to find out more about the product's long-term risks, benefits, and optimal use, or to test the drug in different
populations.

 The FDA may place clinical trials on hold at any
point in this process if, among other reasons, it concludes that clinical subjects are being exposed to an unacceptable health risk. Trials
may also be terminated by IRBs, which must review and approve all research involving human subjects. Side effects or adverse events that
are reported during clinical trials can delay, impede or prevent marketing authorization.

 The results of the preclinical and clinical testing,
along with information regarding the manufacturing of the product and proposed product labeling, are evaluated and, if determined appropriate,
submitted to the FDA through a BLA. The application includes all relevant data available from pertinent preclinical and clinical trials,
including negative or ambiguous results as well as positive findings, together with detailed information relating to the product's
chemistry, manufacturing, controls and proposed labeling, among other things. Once the BLA submission has been accepted for filing,
the FDA's standard goal is to review applications within ten months of the filing date or, if the application relates to a drug
that treats a serious condition and would provide a significant improvement in safety or effectiveness qualifying for Priority Review,
six months from the filing date. The review process is often significantly extended by FDA requests for additional information or
clarification.

 The FDA offers certain programs, such as Breakthrough
Therapy Designation ("BTD") and Fast Track designation, designed to expedite the development and review of applications for
products intended for the treatment of a serious or life-threatening disease or condition. For BTD, preliminary clinical evidence of the
product indicates that it may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints,
such as substantial treatment effects observed early in clinical development. If BTD or Fast Track designation is obtained, the FDA may
initiate review of sections of a BLA before the application is complete, and the product may be eligible for accelerated approval. However,
receipt of BTD or Fast Track designation for a product candidate does not ensure that a product will be developed or approved on an expedited
basis, and such designation may be rescinded if the product candidate is found to no longer meet the qualifying criteria.

 The FDA reviews the BLA to determine, among other
things, whether the proposed product is safe, pure and potent, which includes determining whether it is effective for its intended use,
and whether the product is being manufactured in accordance with cGMP, to assure and preserve the product's identity, strength,
quality, potency and purity. The FDA may refer an application to an advisory committee for review, evaluation and recommendation as to
whether the application should be approved, and applications for new molecular entities and original BLAs are generally discussed at advisory
committee meetings unless the FDA determines that this type of consultation is not needed under the circumstances. The FDA is not bound
by the recommendation of an advisory committee, but it typically follows such recommendations.

 After the FDA evaluates the BLA and conducts inspections
of manufacturing facilities, it may issue an approval letter or a complete response letter ("CRL"). An approval letter authorizes
commercial marketing of the biologic product with specific prescribing information for specific indications. A CRL indicates that the
review cycle of the application is complete and the application is not ready for approval. A CRL may require additional inspections, and/or
other significant, expensive and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. Even if
such additional information is submitted, the FDA may ultimately decide that the BLA does not satisfy the criteria for approval. The FDA
could approve the BLA with a Risk Evaluation and Mitigation Strategy ("REMS") plan to mitigate risks, which could include medication
guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and
other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling, development of
adequate controls and specifications, or a commitment to conduct one or more post-market studies or clinical trials. Such post-market
testing may include Phase IV clinical trials and surveillance to further assess and monitor the product's safety and effectiveness
after commercialization.

 Foreign Regulation

 In addition to regulations in the United States,
we are subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of product candidates
we plan to develop, and products being marketed outside of the United States. We must obtain approval by the comparable regulatory authorities
of foreign countries before we can commence clinical trials or marketing of any products in those countries. The approval process varies
from country to country, and the time may be longer or shorter than that required by the FDA for BLA licensure. The requirements governing
the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.

 Manufacturing

 We currently do not possess any internal manufacturing
infrastructure or capabilities. For any new product candidates, we plan to rely on internal manufacturing and development capabilities,
as capital resources become available and capabilities are developed, in addition to third-party contract manufacturing and development
organizations, or CDMOs, to manufacture biological product candidates for clinical testing, as well as for commercial manufacture if any
product candidates receive marketing approval. We believe that this hybrid strategy will enable us to control and manage preclinical and
early-stage clinical manufacturing while outsourcing other aspects of manufacturing and later-stage clinical manufacturing that would
likely require higher infrastructure cost to build and operate. As with any supply program, obtaining pre-clinical and clinical materials
of sufficient quality and quantity to meet the requirements of our development programs cannot be guaranteed and we cannot ensure that
we will be successful in this endeavor. To date, we have not manufactured any products candidates due to our limited capital resources.

 Sales
and Marketing

 None of our historical product candidates has
been approved for sale. If and when a product candidate advances closer to marketing approval, we may commercialize them on our own in
the United States and potentially with pharmaceutical or biotechnology partners in other geographies. We currently have no sales, marketing
or commercialization capabilities and have no experience as a company doing such activities. However, we may build the necessary capabilities
and infrastructure over time following the advancement of our product candidates. Clinical data, the size of the opportunity and the size
of the commercial infrastructure required will influence our commercialization plans and decision making.

 Competition

 Competition in the pharmaceutical and biotechnology
industry is intense and characterized by aggressive research and development and rapidly evolving science, technology, and standards of
medical care throughout the world. Regarding our competitive position in the industry and our focus on immunotherapies for the treatment
of cancer, we would face competition with all other immuno-oncology products either in development or already approved. Many of the companies
against which we may compete in the future, such as biotechnology and pharmaceutical companies focused on cancer immunotherapies, including
but not limited to, Amgen, Inc., AstraZeneca plc, Bristol-Myers Squibb Company ("BMS"), Genentech, Inc., GlaxoSmithKline PLC,
Merck & Co., Inc., Novartis AG, Pfizer Inc., Roche Holding Ltd and Sanofi S.A., all have significantly greater financial resources
and expertise in research and development, manufacturing, conducting preclinical studies, conducting clinical trials, obtaining regulatory
approvals and marketing approved products than we do. Oncology drugs and therapeutics on the market range from traditional cancer therapies,
including chemotherapy, to immune checkpoint inhibitors targeting CTLA-4, such as BMS' YERVOY, and PD-1/PD-L1, such as BMS'
OPDIVO, Merck & Co.'s KEYTRUDA and Genentech's TECENTRIQ, to T cell-engager immunotherapies, such as Amgen's
BLINCYTO and to oncolytic immunotherapies, including Amgen's T-Vec, an FDA-approved oncolytic immunotherapy for treating advanced
melanoma.

 Moreover, mergers and acquisitions in the pharmaceutical
and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and
other early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and
established companies. Potential competitors also include academic institutions, government agencies and other public and private research
organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing
and commercialization. These third parties also compete with us in recruiting and retaining qualified scientific and management personnel,
establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to,
or necessary for, our programs. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize
products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products
that we may develop. In addition, our ability to compete may be affected in many cases by insurers or other third-party payers seeking
to encourage the use of biosimilar or generic products.

 ITEM 1A.

 RISK FACTORS

 Investing in our common stock is speculative
and illiquid and involves a high degree of risk including the risk of a loss of your entire investment. You should carefully consider
the risks and uncertainties described below and the other information contained in this Annual Report on Form 10-K ("Report")
before investing in our common stock. The risks set forth below are not the only ones facing us. Additional risks and uncertainties may
exist that could also adversely affect our business, operations and prospects. If any of the following risks actually materialize, our
business, financial condition, prospects and/or operations could suffer. In such event, the value of our common stock could decline, and
you could lose all or a substantial portion of the money that you pay for our common stock.

 Risks
Related to Our Operations

 While the Company's financial statements
have been prepared on a going concern basis, we do not currently have sufficient working capital to fund our planned operations for the
next twelve months and we may be required to cease our operations altogether if we are unable to secure sufficient funding.

 There is substantial doubt about our ability to
continue as a going concern, as we currently do not have adequate financial resources to fund our forecasted operating costs for at least
twelve months from the filing of this Report. As of December 31, 2023, the Company had incurred operating losses since inception, and
continues to generate losses from operations, and has an accumulated deficit of $7,916,337. As a result, our existing cash resources are
not sufficient to meet our anticipated needs over the next twelve months from the date hereof and we would need to raise additional capital
to continue our operations and to implement our business plan, which capital is unlikely to be available on favorable terms or at all.
These matters raise substantial doubt about the Company's ability to continue as a going concern.

 If we raise funds from the issuance of equity
securities (which will be challenging in light of current market conditions combined with our early stage of development), substantial
dilution to our existing stockholders would likely result. If we raise additional funds by incurring debt financing (also challenging
in light of current market conditions combined with our early stage of development), the terms of the debt may involve significant cash
payment obligations as well as covenants and specific financial ratios that may restrict our ability to operate our business. Further,
any contracts or license arrangements we enter into to raise funds may require us to relinquish our rights to our products or technology,
and we may not be able to enter into any such contracts or license arrangements on favorable terms, or at all. Since the closing date
of the Reverse Merger, our limited cash position has required us to perform only limited development activities and to delay and scale
back our development programs and other activities to remain afloat. If we continue to have insufficient funds, we may be required to
cease our operations altogether.

 Our ability to pursue the research and development
activities and other initiatives discussed in the following risk factors and elsewhere in this Report will require significant funding,
which may not be available to us in light of current market conditions combined with our early stage of development.

 The consolidated financial statements included
in this Report do not include any adjustments relating to the recoverability and classification of asset amounts or the classification
of liabilities that might be necessary should the Company be unable to continue as a going concern.

 We currently do not have sufficient capital
to pay all amounts owed under our License Agreement with Case Western Reserve University ("CWRU") in the amount of approximately
$407,000 as of December 31, 2023 and on March 22, 2024, we received a notice of termination from CWRU.

 On May 4, 2022, we entered into a License Agreement
with CWRU allowing us to develop and commercialize our lead product candidate, MIE-101. If we fail to comply with our obligations under
the License Agreement, including the payment of all amounts due under the License Agreement, we may lose the rights to developed and potentially
commercialize our lead product candidate, MIE-101, which is the product upon which our business depends. As of December 31, 2023, we have
accrued approximately $407,000 in accrued patent fees payable to CWRU under the License Agreement and we currently do not have sufficient
capital to pay all amounts due under the License Agreement. On March 22, 2024, we received a notice of termination from CWRU. In addition,
there are many risks associated with our financial position and need for additional capital, as further described below under the section
titled "RISKS RELATED TO OUR FINANCIAL POSITION AND NEED FOR ADDITIONAL CAPITAL".

 We may not successfully identify new product
candidates to expand our development pipeline.

 The success of our business over the near term
depends upon our ability to identify and validate new potential cancer therapeutics. Efforts to identify new product candidates require
substantial technical, financial and human resources, and our limited financial resources combined with our methodology may not successfully
identify medically relevant potential therapeutics to be developed as product candidates. Moreover, our research and business development
efforts may identify molecules that initially show promise yet fail to yield product candidates for clinical development for multiple
reasons. For example, potential product candidates may, on further study, be shown to have inadequate efficacy, harmful side effects,
suboptimal drug profiles, suboptimal manufacturability or stability, or other characteristics suggesting that they are unlikely to be
commercially viable products. Our inability to successfully identify additional new product candidates to advance into clinical trials
could have a material adverse effect on our business, financial condition, results of operations and prospects.

 If we are able to raise sufficient capital,
we expect that we will incur significant losses over the next several years and may never achieve or maintain profitability.

 We have limited our operations in advancing our
technology based on the limited amount of capital we have raised. Since the reverse merger in August 2020, we have not raised any capital
other than $575,000 and $341,632 from the issuance of our convertible notes in May 2021 and February 2022, respectively. Due to our limited
operations, our historical results do not reflect the significant costs required to develop a product candidate. In addition, our products
have historically been in preclinical development and therefore, we anticipate that our expenses will increase substantially over the
next several years, if and as we:

 identify and successfully license or acquire
new product candidates or technologies;

 develop product manufacturing processes under
the Food and Drug Administration's ("FDA's") current Good Manufacturing Practice regulations ("cGMP") for
product candidates and enter into manufacturing supply agreements to support toxicology studies and clinical trials;

 contract preclinical toxicology studies to support
the safety of product candidates prior to starting any human trial;

 continue preclinical research and translational
studies to enhance our understanding of the mechanism of action of the product candidates;

 enter into collaboration arrangements with regards
to product discovery and product development;

 pay amounts owed under the former licensing agreement
with Case Western Reserve University and potentially acquire rights to other product candidates and technologies;

 prepare regulatory filings, such as filing IND
applications with the FDA that are required prior to starting any human clinical trial;

 plan, initiate, enroll, and complete clinical
trials;

 maintain, expand and protect intellectual property;
and

 hire additional personnel to support our research,
development, and administrative efforts.

 We expect that it will be several years, if ever,
before we have a product candidate ready for commercialization. If we are unable to license or acquire new product candidates and advance
these product candidates, we may have greater difficulty raising capital on favorable terms, or at all. In addition, there are many risks
associated with our financial position and need for additional capital, as further described below under the section titled "RISKS
RELATED TO OUR FINANCIAL POSITION AND NEED FOR ADDITIONAL CAPITAL".

 If we are able to raise sufficient capital, we
expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. The net losses that we incur
may fluctuate significantly from quarter to quarter and year to year.

 To become and remain profitable, we or a potential
partner must develop and eventually commercialize a product or products with significant market potential. This will require us to be
successful in a range of challenging activities, including completing all phases of clinical trials, obtaining marketing approval and
manufacturing, marketing and selling those products for which we obtain marketing approval. We or a potential partner may never succeed
in these activities and, even if we do, may never generate revenues that are significant or large enough to achieve profitability. If
we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our development efforts
will take several years and will require significant capital that will dilute the ownership interest of common stockholders. A decline
in the value of the Company could also cause stockholders to lose all or part of their investment.

 Our development efforts have historically been
with product candidates in preclinical development.

 We currently do not have any products that have
gained regulatory approval and our development efforts have historically been focused on product candidates in preclinical development.
Our ability to generate product revenues, which we do not expect will occur for several years, if ever, will depend heavily on the successful
development and eventual commercialization of new product candidates. As a result, our business is substantially dependent on our ability
to successfully license or acquire new technologies and complete the development of and obtain regulatory approval for these product candidates.

 If we are unsuccessful in accomplishing the numerous
and complex objectives in developing product candidates, we may not be able to successfully develop and commercialize new product candidates,
and our business will suffer.

 Our short operating history may make it difficult
to evaluate the success of our business to date and to assess our future viability.

 We are an early development stage biotechnology
company formed on March 30, 2020. Our ongoing operations to date have been limited to organizing the Company, business planning, acquiring
rights to license the technology, identifying potential product candidates, and undertaking preclinical studies in collaboration with
our external researchers under university approved grants. In addition, we have limited human resources to help us achieve our goals.
Consequently, any predictions made about our future success or viability based on our short operating history to date may not be as accurate
as they could be if we had a longer and more established operating history. In addition, as an early-stage business, we may encounter
unforeseen expenses, difficulties, complications, delays and other known and unknown factors.

 Business interruptions resulting from the coronavirus
disease (COVID-19) outbreak or similar public health crises could cause a disruption of the development of product candidates and adversely
impact our business.

 In March 2020, the World Health Organization declared
the novel coronavirus disease (COVID-19) outbreak a global pandemic. To limit the spread of COVID-19, governments have taken various actions
including the issuance of stay-at-home orders and physical distancing guidelines. Accordingly, businesses have adjusted, reduced or suspended
operating activities. We may experience disruptions as a result of COVID-19, any variants of COVID-19, or any other pandemic that could
severely impact our business and planned clinical trials, including:

 delays or difficulties in planned clinical site
initiation, including difficulties in recruiting clinical site investigators and clinical site staff;

 delays or difficulties in enrolling patients
in our planned clinical trials and further incurrence of additional costs as a result of preclinical study and clinical trial delays and
adjustments;

 challenges related to ongoing and increased operational
expenses related to any pandemic;

 diversion of healthcare resources away from the
conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the
conduct of clinical trials;

 interruption of key clinical trial activities,
such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers
and others;

 limitations in resources that would otherwise
be focused on the conduct of our business or our clinical trials, including because of sickness or the desire to avoid contact with large
groups of people or as a result of government-imposed "Stay-at-Home" orders or similar working restrictions;

 delays in receiving approval from local regulatory
authorities to initiate our planned clinical trials;

 delays in preclinical and clinical sites receiving
the supplies and materials needed to conduct our planned clinical trials;

 interruption in global shipping that may affect
the transport of clinical trial materials, such as investigational drug product used in our planned clinical trials;

 changes in regulations as part of a response
to the COVID-19 pandemic or any variants of COVID-19 or any other pandemic which may require us to change the ways in which our planned
clinical trials may be conducted, or which may result in unexpected costs;

 delays in necessary interactions with regulators,
ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government
or contractor personnel; and

 increased competition for contract research organizations
("CROs"), suppliers and vendors.

 Should COVID-19 or any variants of COVID-19 or
any other pandemic cases in USA increase, the country or states may institute stricter social distancing protocols.

 Additionally, third parties that we may engage,
including our collaborators, contract organizations, third-party manufacturers, suppliers, clinical trial sites, regulators and other
third parties with whom we conduct business are similarly adjusting their operations and assessing their capacity in light of any pandemic.
If these third parties experience shutdowns or continued business disruptions, our ability to conduct our business in the manner and on
the timelines presently planned could be materially and negatively impacted. It is likely that the disproportionate impact of any pandemic
on hospitals and clinical sites will have an impact on recruitment and retention for our planned clinical trials. In addition, our future
clinical trial sites could experience delays in collecting, receiving and analyzing data from patients enrolled in our planned clinical
trial due to limited staff at such sites, limitation or suspension of on-site visits by patients, or patients' reluctance to visit
the clinical trial sites during the pandemic. As a result, research and development expenses and general and administrative expenses may
vary significantly if there is an increased impact from any pandemic on the costs and timing associated with the conduct of our panned
clinical trial and other related business activities.

 To the extent the any pandemic adversely affects
our business, financial condition and operating results, it may also have the effect of heightening many of the risks described in this
"Risk Factors" section.

 The Company and its subsidiaries have limited
insurance for their operations and are subject to various risks of loss.

 The Company and its subsidiaries carry limited
directors' and officers' insurance. In addition, we do not carry general business liability insurance or other insurance applicable
to our business. Successful claims against the Company would likely render us insolvent. The Company has not reserved any amounts in connection
with self-insuring against any potential claims against the Company or its subsidiaries. Once we are able to raise sufficient funding
to advance our business, we plan to secure additional insurance coverage to better protect our business. There can be no assurance that
we will obtain sufficient insurance coverage to cover all possible risks and potential related losses.

 Drug development involves a lengthy and expensive
process with an uncertain outcome, including failure to demonstrate safety and efficacy to the satisfaction of the FDA or similar regulatory
authorities outside the United States. We may incur additional costs or experience delays in completing, or ultimately be unable to complete,
the product manufacturing of any product candidates.

 The risk of failure for products in preclinical
or early stage of development is high. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate,
we would need to complete formulation development, conduct nonclinical trials, and then conduct extensive clinical trials to demonstrate
the safety and efficacy in humans. In addition, product manufacturing and process development along with preclinical and clinical testing
are all expensive activities, difficult to design and implement, and can take several years to complete. The outcome of preclinical and
clinical trials is inherently uncertain. Failure can occur at any time during the development program, including during the clinical trial
process. Further, the results of preclinical studies and early clinical trials for new product candidates may not be predictive of the
results of later-stage clinical trials. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses,
and many companies that have believed their product candidates performed satisfactorily in preclinical and clinical trials have nonetheless
failed to obtain marketing approval of their products. It is impossible to predict when or if product candidates will prove effective
and safe in humans or will receive regulatory approval.

 We may experience delays in clinical trials, and
we do not know whether any planned clinical trials will begin or enroll subjects on time, need to be redesigned or be completed on schedule,
if at all. There can be no assurance that the FDA or any other foreign regulatory body will not put any product candidate on clinical
hold in the future. We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent
our ability to receive marketing approval or commercialize product candidates. Planned clinical trials may be delayed, suspended or prematurely
terminated for a variety of reasons, such as:

 delay or failure in reaching agreement with the
FDA, European Medicines Agency ("EMA"), or a comparable foreign regulatory authority on a trial design that we want to execute;

 delay or failure in obtaining authorization to
commence a trial or inability to comply with conditions imposed by a regulatory authority regarding the scope or design of a clinical
study;

 delays in reaching, or failure to reach, agreement
on acceptable clinical trial contracts or clinical trial protocols with prospective trial sites;

 inability, delay, or failure in identifying and
maintaining a sufficient number of trial sites, many of which may already be engaged in other clinical programs;

 delay or failure in recruiting and enrolling
suitable subjects to participate in a trial;

 delay or failure in having subjects complete
a trial or return for post-treatment follow-up;

 clinical sites and investigators deviating from
trial protocol, failing to conduct the trial in accordance with regulatory requirements, or dropping out of a trial;

 lack of adequate funding to continue the clinical
trial, including the incurrence of unforeseen costs due to enrollment delays, requirements to conduct additional clinical studies and
increased expenses associated with the services of our contract research organizations ("CROs") and other third parties;

 clinical trials of product candidates may produce
negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon product
development programs;

 the number of patients required for clinical
trials of product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate, or
participants may drop out of these clinical trials at a higher rate than we anticipate;

 we may experience delays or difficulties in the
enrollment of patients that product candidates are designed to target based on the inclusion and exclusion criteria;

 our third-party contractors may fail to comply
with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;

 we may have difficulty partnering with experienced
Clinical Research Organization and study sites that can identify patients that product candidates are designed to target and run our clinical
trials effectively;

 regulators or institutional review boards ("IRBs")
may require that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory
requirements or a finding that the participants are being exposed to unacceptable health risks;

 the supply or quality of product candidates or
other materials necessary to conduct clinical trials of product candidates may be insufficient or inadequate; or

 there may be changes in governmental regulations
or administrative actions.

 If we are required to conduct additional clinical
trials or other testing of product candidates, or if we are unable to successfully complete clinical trials or other testing, or if the
results of these trials or tests are not positive or are only modestly positive, or if there are safety concerns, we may:

 be delayed in obtaining marketing approval for
product candidates, if ever;

 obtain approval for indications or patient populations
that are not as broad as intended or desired;

 obtain approval with labeling that includes significant
use or distribution restrictions or safety warnings that would reduce the potential market for products or inhibit our ability to successfully
commercialize product candidates;

 be subject to additional post-marketing restrictions
and/or testing requirements; or

 have the product removed from the market after
obtaining marketing approval.

 Product development costs will also increase if
we experience delays in testing or marketing approvals. We do not know whether preclinical studies or clinical trials will need to be
restructured or will be completed on schedule, or at all. Significant preclinical or clinical trial delays also could shorten any periods
during which we may have the exclusive right to commercialize product candidates or may allow our competitors to bring products to market
before we do and impair our ability to successfully commercialize new product candidates and may harm our business and results of operations.
In addition, enrollment delays in clinical trials may result in increased development costs, which would cause the value of the Company
to decline and limit our ability to obtain additional financing.

 If serious adverse events or unacceptable side
effects are identified during the development of any product candidates, we may need to abandon or limit our development of these product
candidates.

 If product candidates are associated with undesirable
effects in preclinical or clinical trials or have characteristics that are unexpected, we may need to interrupt, delay or abandon their
development or limit development to more narrow uses or subpopulations in which the undesirable side effects or other characteristics
are less prevalent, less severe or more acceptable from a risk-benefit perspective. Currently unknown, drug-related side effects may be
identified in our planned clinical studies and, as such, these possible drug-related side effects could affect patient recruitment, the
ability of enrolled subjects to complete the trial, or result in potential product liability claims. Reported serious adverse events may
arise and the occurrence, whatever the cause, may impact the conduct of any ongoing or future clinical trial. To date, we have had no
product candidates evaluated in any human clinical studies. Any occurrence of clinically significant adverse events may harm our business,
financial condition and prospects significantly.

 Our business and operations would suffer in
the event of computer system failures, cyber-attacks or deficiencies in our or third parties' cyber security.

 Given our limited operating history, we are still
in the process of implementing our internal security measures. Our internal computer systems and those of current and future third parties
on which we rely may fail and are vulnerable to damage from computer viruses and unauthorized access. Our information technology and other
planned internal infrastructure systems, including corporate firewalls, servers, connection to the Internet, face the risk of systemic
failure that could disrupt our operations. If such an event were to occur and cause interruptions in our operations, it could result in
a material disruption of our development programs and our business operations. To the extent that any disruption or security breach were
to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information,
we could incur liability, our competitive position could be harmed and the further development and commercialization of product candidates
or any future product candidates could be hindered or delayed. In addition, due to limited corporate infrastructure, our entire workforce
is currently working remotely. This could increase our cyber security risk, create data accessibility concerns, and make us more susceptible
to communication disruptions.

 We do not presently maintain insurance coverage
to protect against cybersecurity risks. If we procure such coverage in the future, we cannot ensure that it will be sufficient to cover
any loss we may experience as a result of such cyberattacks. Any cyber incident could have a material adverse effect on our business,
financial condition, and results of operations.

 If we fail to establish and maintain proper
and effective internal control over financial reporting, our operating results and our ability to operate our business could be harmed.

 Ensuring that we will have adequate internal financial
and accounting controls and procedures in place so that we can produce accurate financial statements on a timely basis is a costly and
time-consuming effort that needs to be re-evaluated frequently. Internal control over financial reporting is a process designed to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with Generally
Accepted Accounting Principles or GAAP.

 In addition, we are required to be compliant with
public company internal control requirements mandated under Section 302 and 906 of the Sarbanes-Oxley Act. If we are unable to successfully
maintain internal controls over financial reporting, the accuracy and timing of our financial reporting, and our stock price, may be adversely
affected.

 Risks
Related to Our Financial Position and Need for Additional Capital

 We will need substantial additional funding.
If we are unable to secure sufficient capital in the near term, we may be required to further reduce or eliminate product development
and potentially cease operations.

 As of December 31, 2023, we had cash and cash
equivalents of $156,178 and current liabilities of $4,733,055. Since the closing date of the Reverse Merger, we have been unable to raise
sufficient capital to advance any product candidate from preclinical development into clinical development. Moreover, our existing cash
resources are not sufficient to meet our anticipated needs over the next twelve months from the date hereof. We will need to raise additional
capital to continue our operations and to implement our business plan, which capital is unlikely to be available on favorable terms or
at all. In addition, we expect our expenses to significantly increase if and when we are able to initiate product manufacturing to support
preclinical and clinical testing, perform preclinical studies, including toxicology studies, initiate clinical development, and eventually,
if successful, seek marketing approval for, any product candidates. Since the closing date of the Reverse Merger, our limited cash position
has slowed our product development and other activities to remain afloat. If we are unable to raise additional capital when needed, we
would be forced to further delay our preclinical and clinical development programs and potentially cease our operations altogether.

 If we are able to raise additional capital, our
funding needs may fluctuate significantly based on several factors, including, but not limited to:

 the scope, progress, results and costs of product
development and manufacture of drug product to support preclinical and clinical development of product candidates;

 the extent to which we enter into additional
collaboration arrangements regarding product discovery or development;

 the costs, timing and outcome of regulatory review
of product candidates;

 our ability to establish additional collaborations
with favorable terms, if at all;

 the costs of future commercialization activities,
including product sales, marketing, manufacturing and distribution, for any of product candidates for which we receive marketing approval;

 the costs of preparing, filing and prosecuting
patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

 the costs to in-license technology for new products
or technologies; and

 revenue, if any, received from commercial sales
of product candidates, should any product candidates receive marketing approval.

 Identifying potential product candidates and
conducting manufacturing and process development, preclinical testing and clinical trials is a time-consuming, expensive and uncertain
process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and
achieve product sales. In addition, any product candidates, if approved, may not achieve commercial success. Our commercial revenues,
if any, will be derived from sales of products that we do not expect to be commercially available for several years, if at all. Accordingly,
we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional capital is unlikely
to be available on favorable terms or at all.

 Raising capital will cause dilution to our
stockholders, restrict our operations, or require us to relinquish rights to our technologies or product candidates.

 Until such time, if ever, as we can generate substantial
product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, and/or licensing arrangements.
While we do not have any committed external source of funds, if we raise funds from the issuance of equity securities (which will be challenging
in light of current market conditions combined with our early stage of development), substantial dilution to our existing stockholders
would likely result. If we raise additional funds by incurring debt financing (also challenging in light of current market conditions
combined with our early stage of development), the terms of the debt may involve significant cash payment obligations as well as covenants
and specific financial ratios that may restrict our ability to operate our business. Further, any contracts or license arrangements we
enter into to raise funds may require us to relinquish our rights to our products or technology, and we may not be able to enter into
any such contracts or license arrangements on favorable terms, or at all.

 We cannot be certain that additional funding will
be available on acceptable terms, or at all. If we are unable to raise additional funds when needed, we may be required to delay, limit,
reduce or terminate product development and potentially cease our operations altogether.

 Because the Reverse Merger resulted in an ownership
change under Section 382 of the Internal Revenue Code for PTSC, PTSC's pre-merger net operating loss carryforwards and certain
other tax attributes may be subject to limitations.

 If a corporation undergoes an "ownership
change" within the meaning of Section 382 of the Code, the corporation's net operating loss carryforwards and certain other
tax attributes arising from before the ownership change are subject to limitations on use after the ownership change. In general, an ownership
change occurs if there is a cumulative change in the corporation's equity ownership by certain stockholders that exceeds 50 percentage
points over a rolling three-year period. Similar rules may apply under state tax laws. The Reverse Merger resulted in an ownership change
for PTSC and, accordingly, PTSC's net operating loss carryforwards and certain other tax attributes may be subject to limitations
(or disallowance) on their use after the Reverse Merger. Additional ownership changes in the future could result in additional limitations
on the Company's post-merger net operating loss carryforwards. Consequently, even if the Company achieves profitability, it may
not be able to utilize a material portion of PTSC's, or the post-merger Company's net operating loss carryforwards and other
tax attributes, which could have a material adverse effect on cash flow and results of operations.

 Risks
Related to the Commercialization of Any Product Candidates

 We face substantial competition, which may
result in others discovering, developing or commercializing competing products before or more successfully than we do.

 The development and commercialization of new drug
products is highly competitive. We will face competition with respect to any product candidates that we may seek to develop or commercialize
in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are
a number of large pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of
products for the treatment of cancer. Some of these competitive products and therapies are based on scientific approaches in immuno-oncology
that may be similar to our approach, and others are based on entirely different approaches. Potential competitors also include academic
institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and
establish collaborative arrangements for research, development, manufacturing and commercialization.

 Our commercial opportunity could be reduced or
eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects,
are more convenient or are less expensive than any products that we may develop. In addition, our ability to compete may be affected in
many cases by insurers or other third-party payers seeking to encourage the use of biosimilar or generic products.

 Many of the companies against which we may compete
in the future have significantly greater financial resources and expertise in research and development, manufacturing, conducting preclinical
studies, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Mergers and acquisitions
in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our
competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly through collaborative
arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific
and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies
complementary to, or necessary for, our programs.

 Product liability lawsuits against us could
cause us to incur substantial liabilities and to limit commercialization of any products that we may develop.

 We will face an inherent risk of product liability
exposure related to the testing of product candidates in human clinical trials and will face an even greater risk if we commercially sell
any products that we may develop. If we cannot successfully defend against claims that product candidates or products caused injuries,
we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

 decreased demand for any product candidates or
products that we may develop, if approved;

 injury to our reputation and significant negative
media attention;

 withdrawal of clinical trial participants;

 significant costs to defend the related litigation;

 substantial monetary awards to trial participants
or patients;

 loss of revenue, if approved;

 reduced resources of our management to pursue
our business strategy; and

 the inability to commercialize any products that
we may develop.

 We currently have no product liability insurance
coverage as we do not have any ongoing clinical testing in patients. If we initiate clinical testing in patients, we will secure product
liability insurance, which may not be adequate to cover all liabilities that we may incur. We may need to increase our insurance coverage
as we expand our clinical trials or if we commence commercialization of product candidates. Insurance coverage is increasingly expensive.
We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise.

 Risks
Related to Our Dependence on Third Parties

 Future development collaborations may be important
to us. If we are unable to enter into or maintain these collaborations, or if these collaborations are not successful, our business could
be adversely affected.

 We may in the future determine to seek to collaborate
with pharmaceutical and biotechnology companies for the development of product candidates. We face significant competition in seeking
appropriate collaborators. Our ability to reach a definitive agreement for any collaboration will depend, among other things, upon our
assessment of the collaborator's resources and expertise, the terms and conditions of the proposed collaboration and the proposed
collaborator's evaluation of a number of factors. If we are unable to reach agreements with suitable collaborators on a timely basis,
on acceptable terms, or at all, we may have to curtail the development of a product candidate, reduce or delay its development program
or one or more of our other potential development programs, delay its potential development schedule or reduce the scope of research activities,
or increase our expenditures and all development activities at our own expense. If we fail to enter into collaborations and do not have
sufficient funds or expertise to undertake the necessary development activities, we may not be able to further develop these product candidates,
and our business may be materially and adversely affected.

 If any future collaboration does not result in
the successful development of products or product candidates, product candidates could be delayed, and we may need additional resources
to develop product candidates. All of the risks relating to product development, regulatory approval and commercialization described in
this periodic report also apply to the activities of our collaborators.

 We may contract with third parties for the
manufacture of product candidates for preclinical and clinical studies and may expect to continue to do so for commercialization. This
potential reliance on third parties increases the risk that we will not have sufficient quantities of product candidates or products at
an acceptable cost and quality, which could delay, prevent or impair our development or commercialization efforts.

 Due to our limited operations and no existing
manufacturing infrastructure or capabilities, we may utilize third parties to formulate, manufacture, package, and distribute preclinical
and clinical supplies. In addition, these materials are generally custom-made and available from only a limited number of sources. Despite
drug substance and product risk management, this reliance on third parties presents a risk that we will not have sufficient quantities
of these product candidates or products or such quantities at an acceptable cost or quality, which could delay, prevent or impair our
development or commercialization efforts. Any performance failure on the part of our future manufacturers of drug substance or drug products
could delay clinical development or potential marketing approval.

 We also expect to rely on other third parties
to label, store, and distribute drug supplies for our clinical trials. Any performance failure on the part of our distributors could delay
clinical development or marketing approval of product candidates or commercialization of products, producing additional losses and depriving
us of potential product revenue.

 We may be unable to establish any agreements with
third-party manufacturers or to do so on acceptable terms. Even if we can establish agreements with third-party manufacturers, reliance
on third-party manufacturers entails additional risks, including:

 reliance on the third party for regulatory compliance
and quality assurance;

 the possible breach of the manufacturing agreement
by the third party;

 the possible misappropriation of our proprietary
information, including our trade secrets and know-how; and

 the possible termination or nonrenewal of the
agreement by the third party at a time that is costly or inconvenient for us.

 The third parties we may rely on for manufacturing
and packaging are also subject to regulatory review, and any regulatory compliance problems with these third parties could significantly
delay or disrupt our clinical or commercialization activities. Third-party manufacturers may not be able to comply with cGMP regulations
or similar regulatory requirements outside the United States. Our failure, or the failure of our third-party manufacturers, to comply
with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties,
delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions
and criminal prosecutions, any of which could significantly and adversely affect supplies of products. Additionally, macro-economic conditions
may adversely affect these third parties, causing them to suffer liquidity or operational problems. If a key third-party vendor becomes
insolvent or is forced to lay off workers assisting with our projects, our results and development timing could suffer.

 In addition, any products that we may develop
may compete with other product candidates and products for access to manufacturing facilities. There are a limited number of manufacturers
that operate under cGMP regulations that may be capable of manufacturing for us. Our anticipated future dependence upon others for the
manufacture of product candidates or products may adversely affect our future profit margins and our ability to commercialize any products
that receive marketing approval on a timely and competitive basis.

 Data provided by collaborators and other parties
upon which we rely has not been independently verified and could turn out to be inaccurate, misleading, or incomplete.

 We rely and intend to rely on third-party vendors,
scientists, and collaborators to provide us with significant data and other information related to our projects, clinical trials, and
business. We do not independently verify or audit all of such data (including possibly material portions thereof). As a result, such data
may be inaccurate, misleading, or incomplete.

 Risks Related to Intellectual
Property

 If we are unable to obtain and maintain intellectual
property protection for technology and products we plan to develop or if the scope of the intellectual property protection obtained is
not sufficiently broad, our competitors could develop and commercialize technology and products similar or identical to ours, and our
ability to successfully commercialize our technology and products may be impaired.

 Our success depends in large part on our ability
to obtain and maintain patent protection in the United States, the European Union, and other countries with respect to proprietary technology
and products we plan to develop. We will seek to protect our proprietary position by filing patent applications in the United States and
internationally that are related to novel technologies and product candidates.

 The patent prosecution process is expensive and
time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in
a timely manner. We may choose not to seek patent protection for certain innovations and may choose not to pursue patent protection in
certain jurisdictions, and under the laws of certain jurisdictions, patents or other intellectual property rights may be unavailable or
limited in scope. It is also possible that we will fail to identify patentable aspects of our discovery and preclinical development output
before it is too late to obtain patent protection. Moreover, in some circumstances, we may not have the right to control the preparation,
filing and prosecution of patent applications, or to maintain the patents, covering technology that we license from third parties. Therefore,
these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business.

 The patent position of biotechnology and pharmaceutical
companies generally is highly uncertain, involves complex legal and factual questions and has in recent years been the subject of much
litigation. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States.
Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United
States and other jurisdictions are typically not published until 18 months after filing, or in limited cases not at all. Therefore, we
cannot know with certainty whether we were the first to make the inventions claimed in our owned or licensed patents or pending patent
applications, or that we were the first to file for patent protection of such inventions. Also, an examination is often lengthy and can
involve numerous challenges to the claims sought. As a result, the issuance, scope, validity, enforceability and commercial value of our
patent rights are highly uncertain. Pending and future patent applications may not result in patents being issued which protect our technology
or products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products. Changes
in either the patent laws or interpretation of the patent laws in the United States, the European Union, and other countries may diminish
the value of the underlying patents under our License Agreement or narrow the scope of our patent protection.

 Any inability by us to adequately protect the
underlying intellectual property with respect to proprietary technology and products we plan to develop may have a material adverse effect
on our business, operating results, and financial position.

 If we fail to comply with our obligations under
any license or other agreements under which we may license intellectual property and other rights from third parties or otherwise experience
disruptions to our business relationships with our future licensors, we could lose those rights or other rights which could be the products
upon which our business depends.

 If we fail to comply with our obligations under
any license agreement, or any other future agreement, including the payment of all amounts due under these agreements, we may lose the
rights to developed and potentially commercialize the underlying technology, and the licensor may have the right to terminate the license
agreement or restrict our rights upon notice, in which event we would not be able to develop or market products covered by the agreement,
which could be the products upon which our business depends. For instance, on May 4, 2022, we entered into a License Agreement with CWRU
allowing us to develop and commercialize our former lead product candidate, MIE-101. As of December 31, 2023, we owed CWRU approximately
$407,000 in accrued patent fees under the License Agreement and we did not have sufficient capital to pay all amounts due under the License
Agreement. While CWRU had historically agreed to extend our payment terms, on March 22, 2024, we received a notice of termination from
CWRU (see Note 12 to the accompanying consolidated financial statements).

 We may become involved in lawsuits to protect
or enforce our patents or other intellectual property, which could be expensive, time consuming and unsuccessful.

 Because competition in our industry is intense,
competitors may infringe or otherwise violate our potential rights to patents of our licensors or other intellectual property. To counter
infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. Any claims
we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their
patents. In addition, in a patent infringement proceeding, a court may decide that a patent of ours is invalid or unenforceable, in whole
or in part, construe the patent's claims narrowly, or refuse to stop the other party from using the technology at issue on the grounds
that our patents do not cover the technology in question. An adverse result in any litigation proceeding could put one or more of our
potential patents at risk of being invalidated or interpreted narrowly. We may also elect to enter into license agreements in order to
settle patent infringement claims or to resolve disputes prior to litigation, and any such license agreement may require us to pay royalties
and other fees that could be significant. Furthermore, because of the substantial amount of discovery required in connection with intellectual
property litigation, there is a risk that some of our confidential information could be compromised by disclosure.

 We may need to license certain intellectual
property from third parties, and such licenses may not be available or may not be available on commercially reasonable terms.

 A third party may hold intellectual property,
including patent rights that are important or necessary to the development of potential new products. It may be necessary for us to use
the patented or proprietary technology of third parties to commercialize potential products, in which case, we would be required to obtain
a license from these third parties on commercially reasonable terms, or our business could be harmed, possibly materially. If we were
not able to obtain a license, or we are not able to obtain a license on commercially reasonable terms, our business could be harmed, possibly
materially.

 Third parties may initiate legal proceedings
alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a material
adverse effect on the success of our business.

 Our commercial success depends upon our ability,
and the ability of our licensors and collaborators, to develop, manufacture, market and sell product candidates and use proprietary technologies
without infringing the proprietary rights of third parties. There is considerable intellectual property litigation in the biotechnology
and pharmaceutical industries. We may become party to, or threatened with, future adversarial proceedings or litigation regarding intellectual
property rights with respect to potential new products and technology, including proceedings challenging validity before the United States
Patent and Trademark Office ("USPTO") and/or European Patent Office ("EPO"). Third parties may assert infringement
claims against us based on existing patents or patents that may be granted in the future.

 If we are found to infringe a third party's
intellectual property rights, we could be required to obtain a license from such third party to continue developing and marketing these
products and technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if
we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to
us. We could be forced, including by court order, to cease commercializing any infringing technology or product. In addition, we could
be found liable for monetary damages, including treble damages and attorneys' fees if we are found to have willfully infringed a
patent. A finding of infringement could prevent us from commercializing product candidates or force us to cease some of our business operations,
which could materially harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties
could have a similar negative impact on our business.

 If we are unable to protect the confidentiality
of our trade secrets, our business and competitive position would be harmed.

 In addition to seeking patents for the technology
and product candidates, we also plan to rely on trade secrets, including unpatented know-how, technology and other proprietary information,
to maintain our competitive position. Any NDAs or similar agreements entered into by the Company may not be with all relevant parties,
or adequately protect the confidentiality of our trade secrets. Moreover, to the extent we enter into such agreements, any of these parties
may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate
remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive
and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or
unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor,
we would have no right to prevent them from sharing such trade secrets or from using that technology or information to compete with us.
If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.

 Risks
Related to Our Employee Matters, Managing Growth and Macroeconomic Conditions

 Our future success depends on our ability to
attract, hire, retain and motivate executives, key employees, and our general workforce.

 We are highly dependent on the product development,
clinical and business development expertise of the principal members of our management, scientific and clinical teams. Although we have
entered into offer letters with our executives and employees, each of them may terminate their employment with us at any time. We do not
maintain "key person" insurance for any of our executives or other employees.

 In addition, our business plan relies significantly
on the continued services of our President and Chief Executive Officer, Steven King. If we were to lose his services, including through
death or disability, our ability to continue to execute our business plan would be materially impaired. The Company has not entered into
an employment agreement with Mr. King, or any other officer of the Company.

 Recruiting and retaining qualified scientific,
clinical, regulatory, and manufacturing personnel is critical to our success. Due to the small size of the Company and the limited number
of employees, each of our executives and key employees serves a critical role. The loss of the services of our executive officers or other
key employees could impede the achievement of our development objectives and seriously harm our ability to successfully implement our
business strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time
because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop,
gain regulatory approval of, and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to
hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology
companies for similar personnel. We also may experience competition for the hiring of scientific and clinical personnel from universities
and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us
in product manufacturing, preclinical development, clinical development, regulatory strategy, and commercial strategy. Our consultants
and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities
that may limit their availability to provide services to us. If we are unable to continue to attract and retain high quality personnel,
our ability to pursue our development strategy will be limited.

 We expect to expand our research and development function, as well
as our corporate operations, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

 If we are able to secure sufficient funding, we
would expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas
of product manufacturing, preclinical research, clinical development, and regulatory affairs, as capital resources become available. To
manage our anticipated future growth, we must also implement and improve our managerial, operational and financial systems, identify new
facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources, we may not be able
to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations
may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay
the execution of our business plans or disrupt our operations.

 We may face risks related to securities litigation
that could result in significant legal expenses and settlement or damage awards.

 We may in the future become subject to claims
and litigation alleging violations of the securities laws or other related claims, which could harm our business and require us to incur
significant costs. We are generally obliged, to the extent permitted by law, to indemnify our current and former directors and officers
who are named as defendants in these types of lawsuits. Regardless of the outcome, litigation may require significant attention from management
and could result in significant legal expenses, settlement costs or damage awards that could have a material impact on our financial position,
results of operations and cash flows.

 Risks
Related to Our Common Stock

 There is a substantial lack of liquidity of
our common stock and volatility risks, and because there is no active public trading market for our common stock, you may not be able
to resell your common stock.

 Our common stock is not listed on any securities
exchange and is quoted on the OTC Pink Open Market ("OTC Pink") under the symbol "CPMV." The trading volume of
our common stock historically has been limited and sporadic, and the stock prices have been volatile. There can be no assurance that there
will be an active market for our shares of common stock either now or in the future or that stockholders will be able to liquidate their
investment or liquidate it at a price that reflects the value of the business. As a result, our stockholders may not find purchasers for
our securities should they desire to sell them. We cannot give you any assurance that a broader or more active public trading market for
our common stock will develop or be sustained. In addition, if our shares of common stock cease to be quoted, holders would find it more
difficult to dispose of or to obtain accurate quotation as to the market value of our common stock, and as a result, the market value
of our common stock likely would decline.

 The market for our common stock is subject
to rules relating to low-priced stock ("Penny Stock") which may limit our ability to raise capital.

 Our common stock is currently subject to the "penny
stock rules" adopted pursuant to Section 15(g) of the Exchange Act. In general, the penny stock rules apply to non-Nasdaq or non-national
stock exchange companies whose common stock trades at less than $5.00 per share or which have tangible net worth of less than $5,000,000
($2,000,000 if the company has been operating for three or more years). Such rules require, among other things, that brokers who trade
"penny stock" on behalf of persons other than "established customers" complete certain documentation, make suitability
inquiries of investors and provide investors with certain information concerning trading in the security, including a risk disclosure
document, quote information, broker's commission information and rights and remedies available to investors in penny stocks. Many
brokers have decided not to trade "penny stock" because of the requirements of the penny stock rules, and as a result, the
number of broker-dealers willing to act as market makers in such securities is limited. The "penny stock rules," therefore,
may have an adverse impact on the market for our common stock and may affect our ability to raise additional capital.

 FINRA sales practice requirements may limit
a stockholder's ability to buy and sell our common stock.

 The Financial Industry Regulatory Authority, or
FINRA, has adopted rules requiring that, in recommending an investment to a customer, a broker-dealer must have reasonable grounds for
believing that the investment is suitable for that customer. Prior to recommending speculative or low-priced securities to their non-institutional
customers, broker-dealers must make reasonable efforts to obtain information about the customer's financial status, tax status,
investment objectives and other information. Under interpretations of these rules, FINRA has indicated its belief that there is a high
probability that speculative or low-priced securities will not be suitable for at least some customers. If these FINRA requirements are
applicable to us or our securities, they may make it more difficult for broker-dealers to recommend that at least some of their customers
buy our common stock, which may limit the ability of our stockholders to buy and sell our common stock and could have an adverse effect
on the market for and price of our common stock.

 Future sales of shares by existing stockholders
could cause the Company's stock price to decline.

 If existing stockholders of the Company sell,
or indicate an intention to sell, substantial amounts of the Company's common stock in the public market, the trading price of
the common stock could decline significantly. After the Reverse Merger, shareholders of Private Mosaic currently own a majority of the
fully diluted shares of common stock outstanding, on an as-converted basis. In addition, our shareholders are not restricted in the price
at which they can sell their shares. Shares sold at a price below the current market price at which our common stock is trading may cause
the market price of our common stock to decline.

 We expect our stock price to be volatile, and
the market price of our common stock may drop unexpectedly.

 The market price of our common stock could be
subject to significant fluctuations. For instance, during the year ended December 31, 2023, the low and high trading prices of our common
stock ranged from $0.50 to $1.25 per share. Market prices for securities of early-stage pharmaceutical, biopharmaceutical, and other life
sciences companies have historically been particularly volatile.

 Some of the factors that may cause the market
price of our common stock to fluctuate include:

 results from preclinical testing and clinical
trial results, and our ability to obtain regulatory approvals for product candidates, and delays or failures to obtain such approvals;

 issues in manufacturing these product candidates;

 the entry into, or termination of, key agreements,
including the termination of our License Agreement with CWRU and any future license agreement;

 the initiation of, material developments in,
or conclusion of litigation to enforce or defend intellectual property rights or defend against the intellectual property rights of others;

 announcements by competitors of new commercial
products, clinical progress or the lack thereof, significant contracts, or commercial relationships;

 the introduction of technological innovations
or new therapies that compete with our potential products;

 the loss of key employees;

 general and industry-specific economic conditions
that may affect our research and development expenditures;

 changes in the structure of healthcare payment
systems;

 issuance of new shares of common stock from raising
additional capital, which may not be available on acceptable terms, or at all; and

 period-to-period fluctuations in our financial
results.

 Moreover, the stock markets in general have experienced
substantial volatility that has often been unrelated to the operating performance of individual companies. These broad market fluctuations
may also adversely affect the trading price of our common stock.

 In the past, following periods of volatility in
the market price of a company's securities, stockholders have often instituted class action securities litigation against those
companies. Such litigation, if instituted, could result in substantial costs and diversion of management attention and resources, which
could significantly harm our financial position.

 Our share price could decline as a result of
short sales.

 When an investor sells stock that he does not
own, it is known as a short sale. The seller, anticipating that the price of the stock will go down, intends to buy stock to cover his/her
sale at a later date. If the price of the stock goes down, the seller will profit to the extent of the difference between the price at
which he originally sold it less his later purchase price. Short sales enable the seller to profit in a down market. Short sales could
place significant downward pressure on the price of our common stock. Penny stocks which do not trade on an exchange, such as our common
stock, are particularly susceptible to short sales.

 We may issue preferred stock, and the terms
of such preferred stock may reduce the value of our common stock.

 We are authorized to issue up to a total of 5,000,000
shares of preferred stock in one or more series, of which, 4,300,000 have been undesignated as of December 31, 2023. Our Board of Directors
may determine whether to issue shares of preferred stock without further action by holders of our common stock. If we issue shares of
preferred stock, it could affect the rights or reduce the value of our common stock. In particular, specific rights granted to future
holders of preferred stock could be used to restrict our ability to merge with or sell our assets to a third party. These terms may include
voting rights, preferences as to dividends and liquidation, conversion and redemption rights, and sinking fund provisions. As we seek
capital for our business, such capital may be raised through the issuance of preferred stock.

 Our executive officers, directors and principal
stockholders, if they choose to act together, will have the ability to control all matters submitted to stockholders for approval.

 Shareholders of Private Mosaic beneficially own
shares representing a majority of our capital stock outstanding as of December 31, 2023, on an as-converted basis. As a result, if these
stockholders were to choose to act together, they would be able to control all matters submitted to our stockholders for approval, as
well as our management and affairs. For example, these persons, if they choose to act together, would control the election of directors
and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership control may:

 delay, defer or prevent a change in control;

 entrench our management and the board of directors;
or

 impede a merger, consolidation, takeover or other
business combination involving the Company that other stockholders may desire.

 Our amended and restated certificate of incorporation
and amended and restated bylaws provides that state or federal court located within the state of Delaware will be the sole and exclusive
forum for substantially all disputes between us and our stockholders, which could limit its stockholders' ability to obtain a favorable
judicial forum for disputes with us or our directors, officers or other employees.

 Section XIV of our amended and restated certificate
of incorporation provides that "Unless the Corporation consents in writing to the selection of an alternative forum, the Court of
Chancery of the State of Delaware shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for any stockholder
(including a beneficial owner) to bring (A) any derivative action or proceeding brought on behalf of the Corporation, (B) any action asserting
a claim of breach of a fiduciary duty owed by any director, officer, employee or agent of the Corporation to the Corporation or the Corporation's
stockholders, (C) any action asserting a claim against the Corporation, its directors, officers or employees or agents arising pursuant
to any provision of the DGCL, this Amended and Restated Certificate of Incorporation or the Corporation's bylaws, or (D) any action
asserting a claim against the Corporation, its directors, officers or employees or agents governed by the internal affairs doctrine, except
as to each of (A) through (D) above, for any claim as to which the Court of Chancery determines that there is an indispensable party not
subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the
Court of Chancery within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other
than the Court of Chancery, or over which the Court of Chancery does not have subject matter jurisdiction. To the fullest extent permitted
by law, any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Corporation shall be deemed
to have notice of and consented to the provisions of this Article XIV."

 The exclusive forum provision in our amended and
restated certificate of incorporation and amended and restated bylaws will not relieve us of our duty to comply with the federal securities
laws and the rules and regulations thereunder, and shareholders will not be deemed to have waived our compliance with these laws, rules
and regulations. This exclusive forum provision may limit a shareholder's ability to bring a claim in a judicial forum of its choosing
for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us or our directors, officers
or other employees. In addition, shareholders who do bring a claim in the state or federal court in the State of Delaware could face additional
litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. The state or federal court of the
State of Delaware may also reach different judgments or results than would other courts, including courts where a shareholder would otherwise
choose to bring the action, and such judgments or results may be more favorable to us than to our shareholders. However, the enforceability
of similar exclusive forum provisions in other companies' certificates of incorporation have been challenged in legal proceedings,
and it is possible that a court could find this type of provision to be inapplicable to, or unenforceable in respect of, one or more of
the specified types of actions or proceedings. If a court were to find the exclusive forum provision contained in our amended and restated
certificate of incorporation to be inapplicable or unenforceable in an action, we might incur additional costs associated with resolving
such action in other jurisdictions.

 Anti-takeover provisions contained in our amended
and restated certificate of incorporation and amended and restated bylaws, as well as provisions of Delaware law, could impair a takeover
attempt.

 The Company's amended and restated certificate
of incorporation and amended and restated bylaws contain provisions that could have the effect of delaying or preventing changes in control
or changes in our management without the consent of our board of directors.

 These provisions include:

 providing that our directors may be removed only
for cause by the affirmative vote of the holders of at least 75% of the voting power of our then outstanding shares of common stock entitled
to vote generally for the election of directors;

 providing that any action required or permitted
to be taken by the stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by
any consent in writing in lieu of a meeting of such stockholders, subject to the rights of the holders of any series of preferred stock
with respect to such series, if any;

 providing that special meetings of our stockholders
may only be called by the board of directors pursuant to a resolution adopted by the affirmative vote of a majority of the board of directors;

 providing that our board of directors can be
divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three-year terms, other
than directors which may be elected by holders of preferred stock, if any. This system of electing and removing directors may tend to
discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it could have the effect
of increasing the length of time necessary to change the composition of a majority of the board of directors. In general, at least two
annual meetings of stockholders will be necessary for stockholders to effect a change in a majority of the members of the board of directors;

 providing that all board vacancies, including
newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then
in office, even if less than a quorum, or by a sole remaining director and shall not be filled by the stockholders;

 providing that our amended and restated bylaws
may only be amended by the affirmative vote of the holders of at least two-thirds of our then outstanding common stock;

 providing the ability of our board of directors
to determine whether to issue shares of our preferred stock and to determine the price and other terms of those shares, including preferences
and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer; and

 limiting the liability of, and providing indemnification
to, our directors and officers.

 These provisions, alone or together, could delay
hostile takeovers and changes in control of the Company or changes in our board of directors and management.

 Any provision of our amended and restated certificate
of incorporation or amended and restated bylaws or Delaware law that has the effect of delaying or deterring a change in control could
limit the opportunity for our security holders to receive a premium for their securities and could also affect the price that some investors
are willing to pay for our securities.

 We do not expect to pay any cash dividends
in the foreseeable future.

 We expect to retain our future earnings, if any,
to fund the development and growth of our business. As a result, capital appreciation, if any, of our common stock will be the sole source
of gain, if any, for any stockholders for the foreseeable future.

 CYBERSECURITY

 Risk Management and Strategy

 We recognize the importance of assessing, identifying,
and managing material risks associated with cybersecurity threats, as such term is defined in Item 106(a) of Regulation S-K. These risks
include, among other things: operational risks, intellectual property theft, fraud, extortion, harm to employees or customers and violation
of data privacy or security laws. While do not presently have any general processes for assessing, identifying, and managing material
risks from cybersecurity threats due to our limited financial resources, we do oversee certain third-party service providers and we plan
to institute broader cybersecurity measures at such time we are able to raise sufficient capital.

 Oversee Third-party Risk

 Because we are aware of the risks associated with
third-party service providers, we oversee and manage these risks by monitoring these third-party service providers and reviewing SOC reports
of these providers and implementing complementary controls, if necessary. This approach is designed to mitigate risks related to data
breaches or other security incidents originating from third parties.

 Risks from Cybersecurity Threats

 We have not encountered cybersecurity challenges
that have materially impaired our operations or financial standing.

 ITEM 2.

 PROPERTIES

 The Company has no properties at December 31,
2023, and at the period covered by this Report, has no agreements to acquire any properties. The Company currently uses the offices of
management at no cost to the Company. The Company expects this arrangement to continue until the Company can raise sufficient capital
to advance its research and development product pipeline.

 Overview

 We are a development-stage biotechnology company
focused on advancing and eventually commercializing immunotherapies for the treatment of cancer. We have historically advanced an early-stage
product candidate, MIE-101, that is based on a naturally occurring plant virus licensed from Case Western Reserve University ("CWRU")
(see Note 12 to the accompanying consolidated financial statements). In addition, we are pursuing new product candidates and platforms
to expand our pipeline based on a deep understanding of immunotherapies.

 Summary of Significant Events

 Private Mosaic, a Delaware corporation, was formed
on March 30, 2020. On July 1, 2020, we signed a Material Transfer, Evaluation, and Exclusive Option Agreement ("License Option Agreement")
with Case Western Reserve University ("CWRU"), granting us the exclusive right to license the cowpea mosaic virus ("CPMV")
platform technology to treat and prevent cancer and infectious diseases in humans and for veterinary use. On May 4, 2022, we entered into
the license agreement with CWRU ("License Agreement") pursuant to our rights granted under the License Option Agreement (see
Note 6 to the accompanying audited consolidated financial statements). On March 22, 2024, we received a notice of termination from CWRU
(see Note 12 to the accompanying consolidated financial statements). On August 19, 2020, Patriot Scientific Corporation (now known as
Mosaic ImmunoEngineering, Inc.) and Private Mosaic entered into a reverse merger transaction, as further described below.

 Reverse Merger

 On August 19, 2020, Patriot Scientific Corporation,
a corporation organized under Delaware law on March 24, 1992 (now known as Mosaic ImmunoEngineering, Inc.) and Private Mosaic entered
into a stock purchase agreement ("Stock Purchase Agreement"), whereby one of the wholly owned subsidiaries of Patriot Scientific
Corporation ("PTSC") merged with and into Private Mosaic, with Private Mosaic surviving as wholly owned subsidiary of PTSC
(the "Reverse Merger"). The transaction closed on August 21, 2020 ("Closing Date") in accordance with the terms
of the Stock Purchase Agreement.

 On the Closing Date, Patriot Scientific Corporation
acquired 100% of the issued and outstanding common stock of Private Mosaic, representing 630,000 shares of its Class A common stock ("Class
A Stock") and 70,000 shares of its Class B common stock ("Class B Stock") (collectively referred to as "Target
Common Stock"). In exchange for the Target Common Stock, the holders of the Class A Stock received 630,000 shares of the Company's
Series A Convertible Voting Preferred Stock ("Series A Preferred") and holders of the Class B Stock received 70,000 shares
of the Company's Series B Convertible Voting Preferred Stock ("Series B Preferred"). Each share of Series A Preferred
converted into 10.194106 shares of common stock as defined in the Series A Certificate of Designation. Each share of Series B Preferred
converts into 11.46837 shares of common stock of the Company, possesses full voting rights, on an as-converted basis, as the common stock
of the Company and contains certain anti-dilution rights, as defined in the Series B Certificate of Designation. On a fully diluted, as
converted basis, the holders of Series A Preferred and Series B Preferred, in aggregate, owned 90% of the issued and outstanding common
stock of the Company as of the Closing Date.

 The Reverse Merger was treated by the Company
as a reverse merger in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP").
For accounting purposes, Private Mosaic was considered to have acquired PTSC as the accounting acquirer because: (i) Private Mosaic
stockholders owned 90% of the combined company, on an as-converted basis, immediately following the Closing Date, (ii) Private Mosaic
directors held a majority of board seats in the combined company and (iii) Private Mosaic management held all key positions in the
management of the combined company. Accordingly, Private Mosaic's historical results of operations replaced PTSC's historical
results of operations for all periods prior to the Closing Date of the Reverse Merger and, for all periods following the Closing Date
of the Reverse Merger, the results of operations of the combined company are included in the Company's financial statements.

 Other Key Corporate Events

 On November 30, 2020, we filed amended and restated
articles of incorporation with the Secretary of State of the State of Delaware ("Amended and Restated Certificate") to change
the name of the Company to Mosaic ImmunoEngineering, Inc. ("Name Change") to align the Company's corporate name with
its new strategic direction, to implement a 1-for-500 reverse stock split ("Reverse Stock Split"), and to reduce the number
of authorized shares of common stock from 600 million to 100 million. The Reverse Stock Split was effective on December 2, 2020. All share
numbers and preferred stock conversion numbers included herein have been retroactively adjusted to reflect the 1-for-500 Reverse Stock
Split. On December 30, 2020, we changed our fiscal year end from May 31 to December 31.

 Our funding has primarily come from the issuance
of convertible notes. On May 7, 2021 and February 18, 2022, we issued unsecured convertible promissory notes in the aggregate principal
amount of $575,000 and $341,632, respectively (see Note 7 to the accompanying consolidated financial statements).

 On July 6, 2022, we entered into a redemption
agreement (the "Redemption Agreement") with Holocom, Inc. ("Holocom") pursuant to which we requested full redemption
of our 2,100,000 shares of Series A Preferred Stock at a redemption price of $0.40 per share, provided Holocom has sufficient capital
to redeem the underlying shares. During the year ended December 31, 2023 and 2022, we received cash proceeds in the amount of $433,000
and $343,000, respectively, upon the redemption of 1,242,500 and 857,500 shares of Series A Preferred Stock, respectively (see Note 4
to the accompanying consolidated financial statements).

 Critical
Accounting Policies and Estimates

 Our consolidated financial statements have been
prepared in accordance with accounting principles generally accepted in the United States of America, which require us to make estimates
and judgments that significantly affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of
contingent assets and liabilities. Actual results could differ from those estimates, and such differences could affect the results of
operations reported in future periods. We believe the following critical accounting policies affect our most significant estimates and
judgments used in the preparation of our consolidated financial statements.

 1.
 Investment in Affiliated Company

 In February 2007, we invested an aggregate of
$370,000 in Holocom, Inc. ("Holocom"), a California corporation that manufactures products that protect information transmitted
over secure networks, in exchange for 2,100,000 shares of Series A Convertible Preferred Stock ("Series A Preferred Stock"),
which represented an approximate 46% ownership interest in Holocom, on an as-converted basis. Pursuant to the articles of incorporation
of Holocom, the Series A Preferred Stock is convertible at our option into shares of common stock of Holocom on a one-to-one basis or
is redeemable at any time after May 31, 2007 at a redemption price equal to $0.40 per share or $840,000 in aggregate, provided Holocom
has sufficient funding to redeem our shares of Series A Preferred Stock.

 On July 6, 2022, we entered into a redemption
agreement (the "Redemption Agreement") with Holocom, pursuant to which we requested full redemption of our Series A Preferred
Stock, provided Holocom has sufficient capital to redeem the underlying shares.

 We recognized the payments for the redemption
of shares of Series A Preferred Stock using a cash basis of accounting rather than an accrual method as we are unable to assert that collection
of amounts due under the Redemption Agreement is probable, regardless of the terms of the Redemption Agreement. As a result, the remaining
redemption amount receivable as of December 31, 2022 was fully reserved and other income was recognized once payments were received. We
would remove the cash basis of accounting designation at such time we believe collection from Holocom is probable based upon sufficient
liquidity or a demonstrated payment history.

 On June 21, 2023, we entered into an amendment
to the Redemption Agreement ("Amendment No. 1") to redeem the remaining 910,000 shares of Series A Preferred Stock outstanding
in exchange for a lump sum payment of $300,000 (in lieu of monthly payments), representing a redemption price of approximately $0.33 per
share. As of December 31, 2023, we redeemed in aggregate, 2,100,000 shares of Series A Preferred Stock, in exchange for aggregate net
proceeds received by us of $776,000 as follows:

 Proceeds received

 $

 $

 Shares of Series A Preferred Stock redeemed

 $

 As of December 31, 2023, Holocom had no further
obligations to us under the Redemption Agreement or any other arrangement (see Note 4 to the accompanying consolidated financial statements).

 2.
 Fair Value of Financial Instruments

 Anti-Dilution Issuance Rights Derivative Liability

 Pursuant to the Series B Preferred Certificate
of Designation, the Series B Preferred includes certain anti-dilution issuance rights, whereby the holder will continue to maintain equity
ownership equal to 10% of the fully diluted shares of common stock outstanding, calculated on an as converted basis, including all other
convertible securities outstanding and reserved for issuance (and excluding stock options issued and outstanding and reserved for issuance
under a Board approved employee stock option plan reserving for issuance no more than ten percent (10%) of the outstanding common stock
of the Company) until we raise the Capital Threshold under the License Agreement (see Note 6 to the accompanying audited consolidated
financial statements). The Capital Threshold was met as of June 30, 2023 and therefore, there was no derivative liability as of December
31, 2023. As of December 31, 2022, the Capital Threshold was approximately $283,000.

 To determine the estimated fair value of the anti-dilution
issuance rights liability, the Company used a Monte Carlo simulation methodology, which models the future movement of stock prices based
on several key variables. At December 31, 2022, the estimated fair value of the anti-dilution issuance rights was $46,700. We initially
recorded the fair value as a derivative liability with a corresponding charge to research and development expense and we will mark-to-market
at each reporting period, with changes in fair value recognized in other income (expense) in the consolidated statement of operations
at each period-end while this derivative instrument is outstanding.

 The primary inputs used in valuing the anti-dilution
issuance rights liability at December 31, 2022 was as follows:

 Fair value of common stock (per share)

 $

 0.99

 Estimated additional shares of common stock

 71,511

 Expected volatility

 130%

 Expected term (years)

 0.25

 Risk-free interest rate

 4.42%

 The fair value of the anti-dilution issuance rights
liability as of December 31, 2022 was determined by management with the assistance of an independent third-party specialist. The computation
of expected volatility was estimated using available information about the historical volatility of stocks of similar publicly traded
companies for a period matching the expected term assumption. In addition, the Company incorporated the estimated number of shares, timing,
and probability of future equity financings in the calculation of the anti-dilution issuance rights liability.

 3.
 Convertible Notes

 The Company follows Financial Accounting Standards
Board ("FASB's") Accounting Standards Codification ("ASC") 480-10, "Distinguishing Liabilities from
Equity" in its evaluation of the accounting for share-settled debt (Convertible Notes). ASC 480-10-25-14 requires liability accounting
for certain financial instruments, including shares that embody an unconditional obligation to transfer a variable number of shares, provided
that the monetary value of the obligation is based solely or predominantly on one of the following three characteristics:

 a)

 A fixed monetary amount known at inception;

 b)

 Variations in something other than the fair value of the issuer's equity shares; or

 c)

 Variations in the fair value of the issuer's equity shares, but the monetary value to the counterparty moves in the opposite direction as the value of the issuer's shares.

 Moreover, equity classification was not an appropriate
classification for the convertible notes because the underlying terms of the convertible notes do not expose the investors to risks and
rewards similar to those of an owner and, therefore, do not create a shareholder relationship. Pursuant to ASC 835-30, the convertible
notes were initially recorded at their amortized cost and are being accreted to their redemption value over the estimated conversion period
using the effective interest method.

 4.
 Income Taxes

 We follow authoritative guidance in accounting
for uncertainties in income taxes. This authoritative guidance prescribes a recognition threshold and measurement requirement for the
financial statement recognition of a tax position that has been taken or is expected to be taken on a tax return and also provides guidance
on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under this guidance,
we may only recognize tax positions that meet a "more likely than not" threshold.

 We follow authoritative guidance to evaluate whether
a valuation allowance should be established against our deferred tax assets based on the consideration of all available evidence using
a "more likely than not" standard. In making such judgments, significant weight is given to evidence that can be objectively
verified. We assess our deferred tax assets annually under more likely than not scenarios in which they may be realized through future
income.

 In addition, utilization of our net operating
loss carryforwards may be subject to an annual limitation due to ownership change limitations that may have occurred as a result of the
Reverse Merger that closed in August 2020, or that could occur in the future, as required by Section 382 of the Internal Revenue Code
of 1986, as amended (the "Code"). These ownership changes may limit the amount of the net operating loss carry forwards that
can be utilized annually to offset future taxable income and tax, respectively. In general, an "ownership change" as defined
by Section 382 of the Code results from a transaction or series of transactions over a three-year period resulting in an ownership change
of more than 50 percentage points of the outstanding stock of a Company by certain stockholders. Moreover, since we will need to raise
substantial additional funding to finance our operations, we may undergo further ownership changes in the future, which could further
limit our ability to use net operating loss carryforwards. As a result, if we generate taxable income, our ability to use some of our
net operating loss carryforwards to offset U.S. federal taxable income may be subject to limitations, which could result in increased
future tax liability to us.

 With the exception of refundable income taxes,
we have determined that it was more likely than not that all of our deferred tax assets will not be realized in the future due to our
continuing pre-tax and taxable losses in addition to the potential loss of deferred tax assets as a result of the change in control (see
Note 1 to the accompanying consolidated financial statements). As a result of this determination, and with the exception for the aforementioned
refundable income taxes, we have recorded a full valuation allowance against our deferred tax assets.

 Results of Operations

 Years Ended December 31, 2023 and 2022

 Research and Development Expenses

 Research and development expenses of approximately
$435,000 for the year ended December 31, 2023 are primarily related to salaries and related costs for personnel in research and development
functions and related consulting fees, including approximately $22,000 in share-based compensation expense. The decrease in research and
development expenses of approximately $613,000 for the year ended December 31, 2023 as compared to the same prior year period was primarily
due to a (i) decrease in payroll and related costs of approximately $253,000 due to a reduced time commitment by certain employees, (ii)
a decrease in share-based compensation expense of approximately $102,000 as the majority of share-based awards have been fully expensed
in prior periods, (iii) a decrease in consulting fees of approximately $263,000 due to a lower time commitment by our independent contractors,
and (iv) a decrease in other expenses of approximately $5,000, which amounts were offset by an increase in technology license maintenance
fees of $10,000.

 Research and development expenses of approximately
$1,048,000 for the year ended December 31, 2022 are primarily related to salaries and related costs for personnel in research and development
functions and related consulting fees associated with advancing the platform technologies of approximately $1,041,000, including approximately
$124,000 in share-based compensation. We believe our research and development expenses will increase significantly over time, provided
we are able to raise sufficient capital to advance our lead program.

 General and Administrative Expenses

 General and administrative expenses of approximately
$964,000 for the year ended December 31, 2023 consist principally of salaries and related costs for personnel and consultants in executive
and administrative functions of approximately $790,000, accounting and filing fees of approximately $53,000, legal fees related to intellectual
property rights of approximately $49,000, director and officer insurance of approximately $43,000, investor and public relation fees of
approximately $15,000, and other expenses of approximately $14,000. The decrease in general and administrative expenses of approximately
$615,000 for the year ended December 31, 2023 as compared to the same prior year period was primarily due to (i) a decrease in legal fees
related to intellectual property rights of approximately $298,000 primarily related to amounts due related to the life-to-date patent
fees owed under the license agreement with Case Western Reserve University executed in the same prior year period, (ii) a decrease in
share-based compensation expense of approximately $171,000 as all outstanding share-based awards have been fully expensed in prior periods,
(iii) a decrease in payroll and consulting fees of approximately $88,000 due to a reduced time commitment by certain employees and consultants,
(iv) a decrease in legal fees of approximately $20,000, (v) a decrease in accounting and filing fees of approximately $27,000 due to fewer
filings with the Securities and Exchange Commission, and (vi) a decrease in other expenses of approximately $11,000.

 General and administrative expenses of approximately
$1,579,000 for the year ended December 31, 2022 consist principally of salaries and related costs for personnel and consultants in executive
and administrative functions of approximately $1,050,000, including approximately $171,000 in share-based compensation expense, fees for
outside legal counsel of approximately $20,000, legal fees related to intellectual property rights of approximately $347,000, audit, tax,
accounting and filing fees of approximately $80,000, director and officer insurance of approximately $45,000, investor and public relation
fees of approximately $21,000, and other fees and expenses of approximately $16,000. We believe our general and administrative expenses
will increase over time as we hire new employees to support key administrative functions and the planned expansion of research and development
personnel, provided we are able to raise sufficient capital to advance our lead program.

 Other Income (Expense)

 Gain on Sale of Holocom Preferred Stock

 On July 6, 2022, we entered into a Redemption
Agreement with Holocom, as amended on June 21, 2023, pursuant to which we requested full redemption of our 2,100,000 shares of Series
A Preferred Stock of Holocom. During the year ended December 31, 2023, we received cash proceeds of $433,000 upon the redemption of 1,242,500
shares of Series A Preferred Stock. During the year ended December 31, 2022, we received cash proceeds in the amount of $343,000 upon
the redemption of 857,500 shares of Series A Preferred Stock.

 Interest Income

 Interest income of approximately $3,000 for the
year ended December 31, 2023 is primarily related to interest earned and received on monthly past due redemption installments from Holocom
under the Redemption Agreement.

 Change in Valuation of Derivative Liability

 The change in valuation of the derivative liability
of approximately $47,000 and $58,000 for the years ended December 31, 2023 and 2022, respectively, pertains to a decrease in the estimated
fair value of the anti-dilution issuance rights pursuant to the Series B Preferred.

 Interest Expense and Accretion to Redemption
Value on Convertible Notes

 Non-cash interest expense of approximately $73,000
and $70,000 for the years ended December 31, 2023 and 2022, respectively, represents interest expense on convertible notes.

 Accretion to redemption value on convertible notes
of approximately $16,000 and $82,000 for the years ended December 31, 2023 and 2022, respectively, pertains to the accretion of the convertible
notes to their redemption value using the effective interest method.

 Liquidity and Capital Resources

 On August 21, 2020, we completed a reverse merger
with PTSC, which provided us $605,215 in cash, cash equivalents, and restricted cash. During May 2021, we raised $575,000 from the issuance
of convertible notes, which included $49,997 of accrued payable to founder that was invested in convertible notes. During February 2022,
we raised an additional $341,632 from the issuance of convertible notes. During the years ended December 31, 2023 and 2022, we received
$433,000 and $343,000 from the redemption of Holocom Series A Preferred Stock. As of December 31, 2023, we had cash and cash equivalents
of $156,178. Our ability to continue our operations is highly dependent on our ability to raise capital to fund future operations. We
anticipate, based on currently proposed plans and assumptions, that our cash on hand will not satisfy our operational and capital requirements
through twelve months from the filing date of this Report.

 Our primary uses of capital to date are primarily
related to payroll, consulting and related costs, corporate formation and ongoing public company expenses, fees associated with license
agreements, including patent related expenses, and costs of the Reverse Merger. On a go forward basis, we will need significant additional
capital to support our research and development efforts, compensation and related expenses, and hiring additional staff (including clinical,
scientific, operational, financial, and management personnel) and to reduce our accrued liabilities. We expect to incur substantial expenditures
in the foreseeable future for the development and potential commercialization of product candidates, provided we are able to raise sufficient
capital.

 We plan to continue to fund losses from operations
and future funding needs through our cash on hand and future equity and/or debt offerings, as well as potential collaborations or licensing
arrangements with other companies.

 There are a number of uncertainties associated
with our ability to raise additional capital and we have no current arrangements with respect to any additional financing. If we raise
funds from the issuance of equity securities (which will be challenging in light of current market conditions combined with our early
stage of development), substantial dilution to our existing stockholders would likely result. If we raise additional funds by incurring
debt financing (also challenging in light of current market conditions combined with our early stage of development), the terms of the
debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict our ability
to operate our business. Further, any contracts or license arrangements we enter into to raise funds may require us to relinquish rights
to products or technology, and we may not be able to enter into any such contracts or license arrangements on favorable terms, or at all.
Since the closing date of the Reverse Merger, our limited cash position has required us to perform only limited development activities
and to delay and scale back our development programs and other activities to remain afloat. If we continue to have insufficient funds,
we may be required to cease our operations altogether.

 In addition, the continuation of disruptions caused
by COVID-19 or other related variants, broad-based inflation, and various economic indicators that the United States economy may be entering
a recession in upcoming quarters may cause investors to slow down or delay their decision to deploy capital which will adversely impact
our ability to fund future operations. Consequently, there can be no assurance that any additional financing on commercially reasonable
terms, or at all, will be available when needed. If we are unable to raise additional capital and continue to have insufficient funds,
we may be required to cease our operations altogether. The above matters raise substantial doubt regarding our ability to continue as
a going concern.

 CONTROLS AND PROCEDURES

 Evaluation of Disclosure Controls and Procedures

 Our management, with the participation of our
President and Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial and accounting
officer, respectively), evaluated the effectiveness of our disclosures controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e)
under the Exchange Act, as of December 31, 2023. The term "disclosure controls and procedures," as defined in Rules 13a-15(e)
and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required
to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported
within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation,
controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits
under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal
financial officers, as appropriate, to allow timely decisions regarding required disclosure.

 Management recognizes that any controls and procedures,
no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily
applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure
controls and procedures as of December 31, 2023, our principal executive officer and principal financial and accounting officer concluded
that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

 Management's Report on Internal Control
Over Financial Reporting

 Our management is responsible for establishing
and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under
the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial
Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2023 based
on the criteria set forth in Internal Control — Integrated Framework – 2013 update issued by the Committee of
Sponsoring Organizations of the Treadway Commission. Based on such evaluation, our management concluded that our internal control over
financial reporting was effective as of December 31, 2023.

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

 Changes in Internal Controls over Financial
Reporting

 Management has determined that, as of December
31, 2023, there were no significant changes in our internal control over financial reporting during the fourth quarter of the year ended
December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

 Inherent Limitations on Internal Control

 A control system, no matter how well conceived
and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the benefits
of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls
can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations
include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple errors. Additionally,
controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of
the control. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events,
and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because
of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

 In addition, projections of any evaluation of
effectiveness to future periods are subject to risks that controls may become inadequate because of changes in conditions, or the degree
of compliance with the policies or procedures may deteriorate.

 ITEM 9B.

 OTHER INFORMATION

 During the three months ended December 31, 2023, no director or officer

directors" within the meaning of Nasdaq Marketplace Rule 5605(a)(2). Under Nasdaq Marketplace Rule 5605(a)(2), a director will not
be considered an "independent director" if, such director at any time during the past three years was an employee of the Company,
or if a director (or a director's family member) accepted compensation from the Company (other than compensation for board or board
committee service) in excess of $120,000 during any twelve month period within the three years preceding the determination of independence.
In addition, a director will not qualify as an "independent director" if, in the opinion of our Board of Directors, that person
has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

 Certain Relationships

 There are no family relationships between or among
the Board or executive officers.

 Annual Meeting Attendance

 Our policy is to invite and encourage each member
of our Board to be present at any annual meetings of stockholders. During the year ended December 31, 2023, there was no annual meeting
of stockholders.

 Director Compensation

 We did not pay any compensation, make any equity
awards or non-equity awards to or pay any other compensation to any of our non-employee directors during the year ended December 31, 2023.
In addition, we reimburse all directors for travel and other necessary business expenses incurred in the performance of their services
for us.

 Board Leadership Structure

 In accordance with our Amended and Restated Bylaws
("Bylaws"), our Chief Executive Officer serves as the Chairman of the Board. The Board determined that in the best interest
of the Company, the most effective leadership structure at this time is not to separate the roles of Chairman and Chief Executive Officer
pursuant to the Bylaws. A combined structure will provide the Company with a single leader who represents the Company to our stockholders,
regulators, business partners and other stakeholders. In addition, this structure will create efficiency in the preparation of the meeting
agendas and related Board materials as the Company's Chief Executive Officer works directly with those individuals preparing the
necessary Board materials and is more connected to the overall daily operations of the Company. Agendas will also be prepared with the
permitted input of the full Board allowing for any concerns or risks of any individual director to be discussed as deemed appropriate.
The Board believes that the Company will benefit from this structure, and Mr. King's continuation in the combined role of the Chairman
and President and Chief Executive Officer is in the best interest of the stockholders.

 In addition, the Board does not currently have
a lead independent director. The Board has determined that this structure is the most effective leadership structure for our Company at
this time based on its size. In addition, our Audit, Compensation and Corporate Governance and Nominating Committees, which oversee critical
matters such as our accounting principles, financial reporting practices and system of disclosure controls and internal controls over
financial reporting, our executive compensation program and the selection and evaluation of our directors and director nominees, each
consist entirely of independent directors.

 Board Risk Oversight

 The Board does not have a standing risk management
committee, but rather administers this oversight function directly through the Board as a whole, as well as through committees of the
Board. For example, the Audit Committee assists the Board in its risk oversight function by reviewing and discussing with management our
accounting principles, financial reporting practices and system of disclosure controls and internal controls over financial reporting.
The Corporate Governance and Nominating Committee will assist the Board in its risk oversight function by periodically reviewing and discussing
with management important corporate governance principles and practices and by considering risks related to our director nominee evaluation
process. The Compensation Committee assists the Board in its risk oversight function by considering risks relating to the design of our
executive compensation programs and arrangements. The full Board considers strategic risks and opportunities from the committees regarding
risk oversight in their areas of responsibility, as necessary. We believe the Board leadership structure facilitates the division of risk
management oversight responsibilities among the Board and its committees and enhances the Board's efficiency in fulfilling its oversight
function with respect to different areas of our business risks and our risk mitigation practices.

 Code of Business Conduct and Ethics

 We have adopted a code of business conduct and
ethics for directors, officers (including our principal executive officer, principal financial officer and principal accounting officer)
and employees, known as the Code of Business Conduct and Ethics. The Code of Business Conduct and Ethics is available on our website at
www.mosaicie.com under the Corporate Governance section of our Investors page. We will promptly disclose on our website (i) the nature
of any amendment to the policy that applies to our principal executive officer, principal financial officer, principal accounting officer
or controller, or persons performing similar functions and (ii) the nature of any waiver, including an implicit waiver, from a provision
of the policy that is granted to one of these specified individuals, the name of such person who is granted the waiver and the date of
the waiver.

 Director Legal Proceedings

 During the past ten years, no director or executive
officer has been involved in any legal proceedings that are material to an evaluation of their ability or integrity to become our director
or executive officer.

 Section 16(a) Beneficial Ownership Reporting Compliance

 Section 16(a) of the Exchange Act requires our
directors, executive officers and persons who beneficially own 10% or more of a class of securities registered under Section 12 of the
Exchange Act to file reports of beneficial ownership and changes in beneficial ownership with SEC. Directors, executive officers and greater
than 10% stockholders are required by the rules and regulations of the SEC to furnish us with copies of all reports filed by them in compliance
with Section 16(a).

 Based solely on our review of the copies of such
forms received by us, or written representations from reporting persons, we believe that our insiders complied with all applicable Section 16(a)
filing requirements during the year ended December 31, 2023.

 Communications with the Board of Directors

 Stockholders who wish to communicate with the
Board may do so by addressing their correspondence to Mosaic ImmunoEngineering, Inc., 9114 Adams Avenue, #202, Huntington Beach, California
92646, Attention: Board of Directors. The Corporate Secretary reviews and forwards correspondence to the appropriate director or group
of directors for response.

 ITEM 12.

 SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

 Share Ownership

 The following table sets forth information, as
of March 29, 2024, regarding the beneficial ownership of our common stock and Series B Preferred by:

 Each person known by us to be a beneficial owner
of more than five percent (5%) of our outstanding common stock;

 each person known by us to be a beneficial owner
of more than five percent (5%) of our Series B Preferred Stock;

 each of our directors;

 each of our named executive officers; and

 all current directors and named executive officers
as a group.

 The amounts and percentage of common stock and
Series B Preferred beneficially owned are reported on the basis of regulations of the Securities and Exchange Commission ("SEC")
governing the determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a "beneficial
owner" of a security if that person has or shares "voting power," which includes the power to vote or to direct the
voting of such security, or "investment power," which includes the power to dispose of or to direct the disposition of such
security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership
within 60 days of March 29, 2024, including, but not limited to, any right to acquire the security upon vesting of a restricted stock
units ("RSUs") or through the exercise of any option or warrant or through the conversion of a security. Any securities not
outstanding that are subject to outstanding RSUs, options, warrants or other convertible securities shall be deemed to be outstanding
for the purpose of computing the percentage of outstanding securities of the class owned by that person, but shall not be deemed to be
outstanding for the purpose of computing the percentage of the class owned by any other person.

 Unless otherwise indicated, each person named
below holds sole investment and voting power, other than the powers that may be shared with the person's spouse under applicable
law. Unless otherwise noted below, each individual's address is 9114 Adams Avenue, #202, Huntington Beach, California 92646.

 ITEM 13.

 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

 Transactions With Directors, Executive Officers
and Principal Stockholders

 Our Audit Committee Charter provides that the
Audit Committee of the Board of Directors will review and approve all related party transactions involving directors or executive officers
and will review and monitor conflicts of interest situations involving such individuals where appropriate, and approve or prohibit any
involvement of such persons in matters that may involve a conflict of interest or taking of a corporate opportunity. There were no transactions,
or series of transactions during the year ended December 31, 2023, nor are there any currently proposed transactions, or series of transactions,
to which we are a party, in which the amount exceeds $120,000, and in which to our knowledge any director, executive officer, nominee,
five percent or greater stockholder, or any member of the immediate family of any of the foregoing persons, has or will have any direct
or indirect material interest.

 Notwithstanding the foregoing, during April 2021,
we entered into consulting agreements (retroactive to September 1, 2020) with Nicole Steinmetz, Ph. D., acting Chief Scientific Officer,
Jonathan Pokorski, Ph. D. (Dr. Steinmetz's spouse), and Steve Fiering, Ph. D., each a co-founder of Private Mosaic and greater than
5% shareholder of the Company ("Related Parties"), for their scientific contributions towards advancing the technology platforms.
During the year ended December 31, 2023, we incurred related party consulting expenses for Dr. Steinmetz, Dr. Pokorski, and Dr. Fiering
in the aggregate amount of $20,000, $10,000 and $500, respectively, included in research and development expenses in the accompanying
consolidated financial statements. Pursuant to the consulting agreements, Dr. Steinmetz, Dr. Pokorski, and Dr. Fiering are initially paid
15% of their monthly amounts up and until the Company is able to raise at least $4 million in new funding. In exchange for the deferral
of consulting payments, the Company agreed to grant each of the Related Parties RSU's with a fair market value equal to 20% of their
deferred cash compensation as of the closing date of the financing (the "20% Deferral"). The number of RSU's to be granted
will be calculated based on the closing price of the Company's common stock on the closing date of the financing and will vest one-year
from the date of grant. There was no share-based compensation expense recorded for year ended December 31, 2023 pertaining to the 20%
Deferral as the terms are unknown and are based on a future performance trigger.

 Director Independence

 Under Nasdaq Marketplace Rule 5605(a)(2), a director
will not be considered an "independent director" if, such director at any time during the past three years was an employee
of the Company, or if a director (or a director's family member) accepted compensation from the Company (other than compensation
for board or board committee service) in excess of $120,000 during any twelve month period within the three years preceding the determination
of independence. In addition, a director will not qualify as an "independent director" if, in the opinion of our Board of
Directors, that person has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities
of a director. Our Board has determined that Dr. Baffi, Ms. Felcyn, Dr. Garnick, and Dr. Steinmetz are "independent directors"
within the meaning of Nasdaq Marketplace Rule 5605(a)(2).

31, 2023, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the
consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023
and 2022, and the results of its operations and its cash flows for each of two years in the period ended December 31, 2023, in conformity
with accounting principles generally accepted in the United States of America.

 Going Concern

 The accompanying consolidated financial statements
have been prepared assuming the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements,
the Company has minimal cash on hand and has not yet generated any revenue. These matters raise substantial doubt about the Company's
ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The consolidated
financial statements do not include any adjustments that might result from the outcome of this uncertainty.

 Basis for Opinion

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

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

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

 Critical Audit Matter

 The critical audit matter communicated below is
a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated
to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and
(2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter
in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit
matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

 Accounting for Convertible Note Agreements

 Critical Audit Matter Description

 As described further in Notes 2 and 7 to the consolidated
financial statements, the terms of the Company's convertible note agreements ("Convertible Notes") entered into with
certain investors contain no maturity or repayment terms and are only convertible upon a future financing.

 Auditing management's accounting for the
Convertible Notes and the appropriate classification was challenging due to the complex nature of the relevant accounting guidance, as
well as the extent of management's judgments in the application of the guidance. Management determined that it was appropriate to
account for the Convertible Notes as share-settled debt as the instruments embody a conditional obligation to issue a variable number
of the Company's equity shares and at inception, the monetary value of the obligation is based solely on a fixed value known at
inception.

 How the Critical Audit Matter Was Addressed
in the Audit

 We obtained an understanding of management's
assessment of the accounting treatment of the Convertible Notes through inspection of the underlying agreements and evaluation of the
Company's analysis of the significant terms of the Convertible Notes, the related accounting guidance and their conclusions. Our
audit procedures related to the accounting for the Convertible Notes included, among others, the following: we evaluated management's
conclusions regarding the accounting and classification of the Convertible Notes, assessed the reasonableness of management's estimated
life of the Convertible Notes, recalculated the accretion to the redemption value during the year ended December 31, 2023, performed a
sensitivity analysis on management's estimated life of the Convertible Notes, and assessed the completeness and accuracy of management's
disclosure of the Convertible Notes.

 For the Years Ended December 31, 2023 and 2022

to the "Company," "Mosaic," "we," "our," or "us" in this Annual Report on
Form 10-K ("Report") refer to Mosaic ImmunoEngineering, Inc. and its subsidiaries.

 1. Organization
and Business

 Mosaic ImmunoEngineering, Inc. (the "Company,"
"Mosaic," "we," "us," or "our"), formerly known as Patriot Scientific Corporation, is
a corporation organized under Delaware law on March 24, 1992. We are a development-stage biotechnology company focused on advancing and
eventually commercializing immunotherapies for the treatment of cancer. We have historically advanced an early-stage product candidate,
MIE-101, that is based on a naturally occurring plant virus licensed from Case Western Reserve University ("CWRU") (see Note
12). In addition, we are pursuing new product candidates and platforms to expand our pipeline based on a deep understanding of immunotherapies
and our license agreements with University of California San Diego.

 The Company has two inactive wholly owned subsidiaries:
Mosaic ImmunoEngineering Development Company, a corporation organized under Delaware law on March 30, 2020 and Patriot Data Solutions
Group, Inc.

 Liquidity and Management's Plans

 The accompanying consolidated financial statements
have been prepared assuming the Company will continue as a going concern. At December 31, 2023, the Company had cash and cash equivalents
of $ 156,178 and has not yet generated any revenue. Therefore, our ability to continue our operations is highly dependent on our ability
to raise capital to fund future operations. We anticipate, based on currently proposed plans and assumptions that our cash and cash equivalents
on hand will not satisfy our operational and capital requirements through twelve months from the filing date of this Annual Report on
Form 10-K.

 There are a number of uncertainties associated
with our ability to raise additional capital and we have no current arrangements with respect to any additional financing. In addition,
the continuation of disruptions caused by COVID-19 or other variants or pandemics, broad-based inflation, and various economic indicators
that the United States economy may be entering a recession in upcoming quarters may cause investors to slow down or delay their decision
to deploy capital which will adversely impact our ability to fund future operations. Consequently, there can be no assurance that any
additional financing on commercially reasonable terms, or at all, will be available when needed. The inability to obtain additional capital
will delay our ability to conduct our business operations. Any additional equity financing may involve substantial dilution to our then
existing stockholders. The above matters raise substantial doubt regarding our ability to continue as a going concern.

 2. Summary
of Significant Accounting Policies

 Basis of Presentation

 The accompanying consolidated financial statements
have been prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") and include the
accounts of Mosaic ImmunoEngineering, Inc. and our subsidiaries. All intercompany accounts and transactions among the consolidated entities
have been eliminated in the consolidated financial statements.

 F- 8

 Segment Reporting

 The Company manages its operations as a single
operating segment for the purposes of assessing performance and making operating decisions. No revenue has been generated since inception,
and all tangible assets are held in the United States.

 Cash and Cash Equivalents

 We consider all highly liquid investments acquired
with a maturity of three months or less from the purchase date to be cash equivalents.

 Investment in Affiliated Company

 In February 2007, we invested an aggregate of
$ 370,000 in Holocom, Inc. ("Holocom"), a California corporation that manufactures products that protect information transmitted
over secure networks, in exchange for 2,100,000 shares of Series A Convertible Preferred Stock ("Series A Preferred Stock"),
which represented an approximate 46 % ownership interest in Holocom, on an as-converted basis. Prior to impairment, this investment was
accounted for at cost since we did not have the ability to exercise significant influence over the operating and financial policies of
Holocom. On July 6, 2022, we entered into a redemption agreement (the "Redemption Agreement") with Holocom, pursuant to which
we requested full redemption of our Series A Preferred Stock at a redemption price equal to $0.40 per share or $ 840,000 in aggregate.
We recognized the initial and monthly redemption of shares of Series A Preferred Stock using a cash basis of accounting rather than an
accrual method as we were unable to assert that collection of amounts due under the Redemption Agreement was probable, regardless of the
terms of the Redemption Agreement (see Note 4).

 Financial Instruments and Concentrations of
Credit Risk

 Financial instruments that potentially subject
us to concentrations of credit risk consist principally of cash and cash equivalents.

 We invest our cash and cash equivalents primarily
in money market funds. Cash and cash equivalents are maintained with high quality financial institutions, which are regularly monitored
by management. At times, deposits held with financial institutions may exceed the amount of insurance provided by the Federal Deposit
Insurance Corporation and the Securities Investor Protection Corporation. We perform ongoing evaluations of these financial institutions
to limit our concentration of risk exposure.

 Fair Value of Financial Instruments

 Our financial instruments consist principally
of cash and cash equivalents, accounts payable, derivative liability, accrued compensation, accrued consulting, accrued expenses and other,
and convertible notes. The carrying value of these financial instruments, except for the derivative liability and convertible notes, approximates
fair value because of the immediate or short-term maturity of the instruments. We record the derivative liability at fair value (see Note
3). The convertible notes are initially recorded at their amortized cost and are accreted to their redemption value over the estimated
conversion period using the effective interest method (see Note 7).

 F- 9

 Use of Estimates

 The preparation of consolidated financial statements
in accordance with U.S. GAAP requires management to make 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 the
anti-dilution issuance rights liability (derivative liability), the timing of conversion of the convertible notes, the provision or benefit
for income taxes and the corresponding valuation allowance on deferred tax assets. In addition, management's assessment of the Company's
ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. On an ongoing
basis, the Company evaluates its estimates, judgments, 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 accounting estimates and
assumptions, the actual financial statement results could differ materially from such accounting estimates and assumptions.

 Convertible Notes

 The Company follows FASB's Accounting Standards
Codification ("ASC") 480-10, "Distinguishing Liabilities from Equity" in its evaluation of the accounting for
share-settled debt. ASC 480-10-25-14 requires liability accounting for certain financial instruments, including shares that embody an
unconditional obligation to transfer a variable number of shares, provided that the monetary value of the obligation is based solely or
predominantly on one of the following three characteristics:

 a)

 A fixed monetary amount known at inception;

 b)

 Variations in something other than the fair value of the issuer's equity shares; or

 c)

 Variations in the fair value of the issuer's equity shares, but the monetary value to the counterparty moves in the opposite direction as the value of the issuer's shares

 Moreover, equity classification was not an appropriate
classification for the convertible notes because the underlying terms of the convertible notes do not expose the investors to risks and
rewards similar to those of an owner and, therefore, do not create a shareholder relationship. Pursuant to ASC 835-30, the convertible
notes were initially recorded at their amortized cost and are accreted to their redemption value over the estimated conversion period
using the effective interest method (see Note 7).

 Assessment of Contingent Liabilities

 We may be involved in various legal matters, disputes,
and patent infringement claims which arise in the ordinary course of our business. We accrue for any estimated losses at the time when
we can make a reliable estimate of such loss and it is probable that it has been incurred. By their very nature, contingencies are difficult
to estimate. We continually evaluate information related to all contingencies to determine that the basis on which we have recorded our
estimated exposure is appropriate.

 Patent Costs

 Patent fees and patent related costs in connection
with filing and prosecuting patent applications are expensed as incurred and are classified as general and administrative expenses in
the accompanying consolidated financial statements.

 F- 10

 Share-Based Compensation

 We account for restricted stock units ("RSUs")
and other share-based awards granted under our equity compensation plan in accordance with the authoritative guidance for share-based
compensation. The fair value of RSUs is measured at the grant date based on the closing market price of our common stock on the date of
grant, and is recognized as expense on a straight-line basis over the period of vesting. Forfeitures are recognized as a reduction of
share-based compensation expense as they occur. At December 31, 2023 and 2022, there were no outstanding share-based awards with market
or performance conditions.

 In addition, we periodically grant RSUs to non-employee
consultants, which we account for in accordance with the authoritative guidance for share-based compensation. The cost of non-employee
services received in exchange for share-based awards are measured based on either the fair value of the consideration received, or the
fair value of the share-based award issued, whichever is more reliably measurable.

 Basic and Diluted Income (Loss) Per Common
Share

 Basic income (loss) per common share is computed
by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the
period. Diluted earnings per common share is computed by dividing our net income (loss) available to common stockholders by the sum of
the weighted average number of common shares outstanding during the period, plus the potential dilutive effects of unvested RSUs and shares
of common stock expected to be issued under our Convertible Notes and Series A and B Preferred during the period.

 The potential dilutive effect of unvested RSUs
outstanding during the period are calculated in accordance with the treasury stock method, but are excluded if their effect is anti-dilutive.
The potential dilutive effect of our Convertible Notes and Series B Preferred Stock outstanding during the period is calculated using
the if-converted method assuming the conversion of Convertible Notes and Series B Preferred as of the earliest period reported or at the
date of issuance, if later, but are excluded if their effect is anti-dilutive.

 The following table presents common share equivalents
excluded from the calculation of diluted net income (loss) per share for the years ended December 31, 2023 and 2022, as the effect of
their inclusion would have been anti-dilutive during periods of net loss:

 Moreover, in connection with an acquisition of
Crossflo by PTSC (see Note 10), 5,690 escrow shares of common stock were issued that are contingent upon certain representations and warranties
made by Crossflo. We exclude these escrow shares from the basic income (loss) per share calculations and would have included the escrowed
shares in the diluted income per share calculations if we reported net income.

 F- 11

 Income Taxes

 We follow authoritative guidance in accounting
for uncertainties in income taxes. This authoritative guidance prescribes a recognition threshold and measurement requirement for the
financial statement recognition of a tax position that has been taken or is expected to be taken on a tax return and also provides guidance
on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under this guidance,
we may only recognize tax positions that meet a "more likely than not" threshold.

 We follow authoritative guidance to evaluate whether
a valuation allowance should be established against our deferred tax assets based on the consideration of all available evidence using
a "more likely than not" standard. In making such judgments, significant weight is given to evidence that can be objectively
verified. We assess our deferred tax assets annually under more likely than not scenarios in which they may be realized through future
income.

 In addition, utilization of our net operating
loss carryforwards may be subject to an annual limitation due to ownership change limitations that may have occurred as a result of the
reverse merger that closed in August 2020, or that could occur in the future, as required by Section 382 of the Internal Revenue Code
of 1986, as amended (the "Code"). These ownership changes may limit the amount of the net operating loss carryforwards that
can be utilized annually to offset future taxable income and tax, respectively. In general, an "ownership change" as defined
by Section 382 of the Code results from a transaction or series of transactions over a three-year period resulting in an ownership change
of more than 50 percentage points of the outstanding stock of a Company by certain stockholders. Moreover, since we will need to raise
substantial additional funding to finance our operations, we may undergo further ownership changes in the future, which could further
limit our ability to use net operating loss carryforwards. As a result, if we generate taxable income, our ability to use some of our
net operating loss carryforwards to offset U.S. federal taxable income may be subject to limitations, which could result in increased
future tax liability to us.

 With the exception of refundable income taxes,
we have determined that it was more likely than not that all of our deferred tax assets will not be realized in the future due to our
continuing pre-tax and taxable losses in addition to the potential loss of deferred tax assets as a result of the reverse merger that
closed in August 2020. As a result of this determination, we have recorded a full valuation allowance against our deferred tax assets.

 Recently Issued Accounting Standards Not Yet Adopted

 As of December 31, 2023, there are no recently
issued accounting standards not yet adopted that may have a material effect on the Company's consolidated financial statements other
than as follows:

 In August 2020, the FASB issued Accounting Standards
Updates ("ASU") 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging
— Contracts in Entity's Own Equity (Subtopic 815-40). The guidance simplifies the accounting for certain financial instruments,
eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments,
and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity's own equity.
It also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity's
own equity and amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible
instruments. The guidance is effective for public business entities that meet the definition of a Securities and Exchange Commission filer,
excluding entities eligible to be smaller reporting companies as defined by the Securities and Exchange Commission, for fiscal years beginning
after December 15, 2021, including interim periods within those fiscal years. For all other entities, the guidance is effective for fiscal
years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier
than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company adopted the guidance
as of January 1, 2024 and is currently assessing the impact of the adoption of this standard on its consolidated financial statements.

 F- 12

 3. Fair
Value of Financial Instruments

 The Company's financial instruments consist
of money market funds as well as an anti-dilution issuance rights liability pursuant to the License Option Agreement with Case Western
Reserve University ("CWRU") (see Note 6). The anti-dilution issuance rights met the definition of a derivative under ASC Topic
815, "Derivatives and Hedging", and the liability was carried at fair value until the Capital Threshold (see Note 6) was met
during June 2023, at which point the anti-dilutions rights were extinguished.

 Under this authoritative guidance, we are required
to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We determine fair value
based on quoted prices when available or through the use of alternative approaches, such as discounting the expected cash flows using
market interest rates commensurate with the credit quality and duration of the investment or valuations by third-party professionals.
The three levels of inputs that we may use to measure fair value are:

 Level 1: Unadjusted quoted prices in active markets
that are accessible at the measurement date for identical, unrestricted assets or liabilities;

 Level 2: Quoted prices in markets that are not active or inputs which are
observable, either directly or indirectly, for substantially the full term of the asset or liability; and

 Level 3: Prices or valuation
techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or
no market activity).

 The following tables set forth the fair value
of the Company's financial assets and liabilities by level within the fair value hierarchy at December 31, 2023 and 2022:

 Anti-Dilution Issuance Rights Derivative Liability

 Pursuant to the Series B Preferred Certificate
of Designation, the Series B Preferred included certain anti-dilution issuance rights, whereby the holder will continue to maintain equity
ownership equal to 10% of the fully diluted shares of common stock outstanding, calculated on an as converted basis, including all other
convertible securities outstanding and reserved for issuance (and excluding stock options issued and outstanding and reserved for issuance
under a Board approved employee stock option plan reserving for issuance no more than ten percent (10%) of the outstanding common stock
of the Company) until we raise the Capital Threshold under the License Agreement (see Note 6). As of June 2023, we received life-to-date
aggregate proceeds in excess of the Capital Threshold and therefore, we recorded no derivative liability as of December 31, 2023. As of
December 31, 2022, the remaining Capital Threshold was $ 283,000.

 To determine the estimated fair value of the anti-dilution
issuance rights liability, the Company used a Monte Carlo simulation methodology, which models the future movement of stock prices based
on several key variables. At December 31, 2022, the estimated fair value of the anti-dilution issuance rights was $ 46,700. We initially
recorded the fair value as a derivative liability with a corresponding charge to research and development expense and we marked-to-market
at each reporting period, with changes in fair value recognized in other income (expense) in the consolidated statements of operations
at each period-end while this derivative instrument was outstanding.

 The primary inputs used in valuing the anti-dilution
issuance rights liability at December 31, 2022 were as follows:

 F- 14

 The fair value of the anti-dilution issuance rights
liability as of December 31, 2022 was determined by management with the assistance of an independent third-party specialist. The computation
of expected volatility was estimated using available information about the historical volatility of stocks of similar publicly traded
companies for a period matching the expected term assumption. In addition, the Company incorporated the estimated number of shares, timing,
and probability of future equity financings in the calculation of the anti-dilution issuance rights liability.

 4. Investment
in Affiliated Companies

 Holocom, Inc.

 In February 2007, we invested an aggregate of
$ 370,000 in Holocom in exchange for 2,100,000 shares of Series A Preferred Stock, which represented an approximate 46 % ownership interest
in Holocom, on an as-converted basis. Pursuant to the articles of incorporation of Holocom, the Series A Preferred Stock is convertible
at our option into shares of Holocom's common stock on a one-to-one basis or is redeemable at any time after May 31, 2007 at a redemption
price equal to $0.40 per share or $840,000 in aggregate, provided Holocom has sufficient funding to redeem our shares of Series A Preferred
Stock.

 On July 6, 2022, we entered into the Redemption
Agreement with Holocom, pursuant to which we requested full redemption of our Series A Preferred Stock. Pursuant to the Redemption Agreement,
we received cash proceeds in the amount of $ 336,000
 upon the redemption of 840,000
 shares of Series A Preferred Stock in July 2022 with the remaining shares of Series A Preferred Stock were to be redeemed over
a period of thirty (30) months beginning August 1, 2022 based on the following redemption schedule:

 We recognized the initial and monthly redemption
of shares of Series A Preferred Stock using a cash basis of accounting rather than an accrual method as we were unable to assert that
collection of amounts due under the redemption agreement was probable, regardless of the terms of the Redemption Agreement. Any amounts
not paid within fifteen (15) days of its respective due date accrued interest at a rate of 8% per annum until fully paid and retroactively
adjusted to 12% per annum from its original due date for amounts not paid within 90 days of its original due date.

 During the year ended December 31, 2022, of the
175,000 shares of Series A Preferred Stock to be redeemed under the aforementioned redemption schedule, Holocom redeemed 17,500
 shares of Series A Preferred Stock in exchange for proceeds of $ 7,000.
During the three months ended March 31, 2023, 192,500 shares of Series A Preferred Stock were redeemed in exchange for proceeds of $ 77,000,
including redemption amounts that were past due as of December 31, 2022. On June 21, 2023, we entered into an amendment to the Redemption
Agreement ("Amendment No. 1") to redeem the remaining 910,000 shares of Series A Preferred Stock outstanding in exchange
for a lump sum payment of $300,000 (in lieu of monthly payments), representing a redemption price of approximately $0.33 per share. As
of December 31, 2023, we redeemed in aggregate, 2,100,000
 shares of Series A Preferred Stock, in exchange for aggregate net proceeds received by us of $ 776,000
 as follows:

 6. License
Agreements

 License Option and Agreement with CWRU

 On July 1, 2020, we signed a License Option Agreement
with CWRU, granting the Company the exclusive right to license certain technology covering an immunotherapy platform technology to treat
and prevent cancer in humans and for veterinary use, including MIE-101, our lead clinical candidate. Under the License Option Agreement,
CWRU granted us the exclusive option for a period of two (2) years to negotiate and enter into a license agreement with CWRU, provided
that we meet certain diligence milestones.

 Under the License Option Agreement, we issued
CWRU 70,000 shares of Class B Common Stock at the fair market value of $7 on the date of issuance. On August 21, 2020, the Class B Stock
was exchanged for shares of Series B Preferred, which included certain anti-dilution rights. Pursuant to the Certificate of Designation,
the Series B Preferred holder will maintain ownership equal to 10% of the fully diluted shares of common stock outstanding of the Company,
including for such purposes all other convertible securities outstanding and reserved for issuance except stock options issued and outstanding
and reserved for issuance under a board approved employee stock option plans reserving for issuance no more than ten percent (10%) of
the outstanding common stock of the Company then outstanding, until we raise at least $1 million from the sale of either preferred, common
stock, or from the net working capital acquired under the reverse merger in August 2020, or any combination thereof ("Capital Threshold").
The anti-dilution issuance rights under the License Option Agreement meet the definition of a derivative instrument under ASC Topic 815
(see Note 3). Initially, the net working capital acquired under the reverse merger in August 2020 of approximately $374,000 was applied
against the Capital Threshold. Subsequent to the closing date of the reverse merger, we received additional net working capital under
the reverse merger through aggregate payments received from the redemption of Holocom preferred stock (see Note 4) in the amount of $776,000
since such investment existed as of closing date of the reverse merger in August 2020 and was not included in net working capital as of
the closing date. Therefore, as of June 2023, we received in excess of $1 million in net working capital under the reverse merger and
have met the Capital Threshold. As such, there is no remaining derivative liability as of December 31, 2023.

 F- 16

 On May 4, 2022, we exercised our rights under
the License Option Agreement and entered into a license agreement with CWRU ("License Agreement"). Pursuant to the terms of
the License Agreement, we agreed to pay CWRU for each licensed product used in human applications (i) development milestones of up to
$1.8 million in aggregate dependent upon the progress of clinical trials, regulatory approvals, and initiation of product launch, (ii)
tiered royalty on net sales beginning in the mid-single digits, (iii) annual minimum royalty of $10,000 beginning on the second anniversary
date of the Agreement with the minimum amount rising based on net sales of the licensed product, and (iv) a declining percentage of all
non-royalty sublicensing income based on the escalating stage of development upon a sublicensing event, if applicable. In addition, we
agreed to pay CWRU for each licensed product used in veterinarian applications (i) a tiered royalty on net sales beginning in the low
single digits and (ii) a declining percentage of all non-royalty sublicensing income based on the escalating stage of development upon
a sublicensing event, if applicable.

 In addition, we are responsible for the reimbursement
of all past, current and future patent fees incurred by CWRU under the License Agreement. During the years ended December 31, 2023 and
2022, we incurred $ 42,467 and $ 327,922, respectively, in patent legal fees associated with the License Agreement, which amounts are included
in general and administrative expenses in the accompanying consolidated statements of operations.

 Furthermore, we agreed to reimburse CWRU for all
intellectual property fees incurred since inception of the portfolio through the date of the License Agreement in the amount of approximately
$ 303,000 (included in Accrued expenses and other in the accompanying condensed consolidated balance sheets) in four (4) equal quarterly
installments beginning upon the sooner of (i) August 31, 2022 or (ii) upon the Company closing a financing in the amount of $5 million
or more. Due to our limited cash position, as of December 31, 2023, we have not paid any amounts owed to CWRU and we continue to seek
additional time to raise sufficient capital in order to pay amounts due to CWRU. While CWRU has previously provided us additional time
to pay amounts due under the License Agreement beyond the initial August 31, 2022 due date, there were no guarantees that CWRU will grant
us any additional extension of time to pay amounts due under the License Agreement. If we fail to comply with our obligations under the
License Agreement, including the payment of all amounts due under the License Agreement, we may lose the rights to develop and potentially
commercialize our technology, and CWRU may have the right to terminate the License Agreement or restrict our rights, in which event we
would not be able to develop or market products covered by the License Agreement, which are the products upon which our business depends.
On March 22, 2024, we received a notice of termination from CWRU to terminate the License Agreement effective immediately (see Note 12).
As of December 31, 2023 and 2022, we have accrued $ 406,973 and $ 364,507, respectively, in accrued patent fees under the License Agreement.

 License Agreements with University of California
San Diego ("UC San Diego")

 During July 2021, we licensed the exclusive rights
from UC San Diego to develop and commercialize technology that involves the loading of immuno-stimulatory molecules into plant virus protein
nanoparticles. These plant virus protein nanoparticles can be loaded with other TLR agonists to further tailor specific immune response
parameters. Under the licensing agreement, we are obligated to pay (i) a nominal upfront license access fee, (ii) all patent costs incurred
prior to the effective date of the license agreement, (iii) annual license maintenance fees beginning on the second anniversary date of
the agreement, (iv) aggregate future milestone payments based on potential clinical development and regulatory milestones of up to $165,000
through Phase III development plus additional milestones upon regulatory approval in the U.S. and other countries, (v) potential sales
milestones upon achieving certain sales levels, and (vi) a low single digit royalty on net sales and/or a percentage of sublicense income.

 During September 2021, we licensed the exclusive
rights to develop and commercialize several novel vaccine candidates, including SARS-CoV-2 and other infectious disease applications from
UC San Diego. Under the licensing agreement, we are obligated to pay (i) a nominal upfront license access fee, (ii) all patent costs incurred
prior to the effective date of the license agreement, (iii) annual license maintenance fees beginning on the second anniversary date of
the agreement, (iv) aggregate future milestone payments based on potential clinical development and regulatory milestones of up to $ 1,250,000
through Phase III development plus additional milestones upon regulatory approval in the U.S. and other countries, and (v) a low single
digit royalty on net sales and/or a percentage of sublicense income. On July 12, 2023, we provided notice to UC San Diego to terminate
the September 2021 license agreement based on our evaluation of our licensed technology portfolio and our focus on advancing our lead
oncology candidate, MIE-101.

 F- 17

 During the years ended December 31, 2023 and 2022,
we incurred $ 6,200 and $ 19,080, respectively, in intellectual property costs associated with the license agreements with UC San Diego,
which amount is included in general and administrative expense in the accompanying consolidated statements of operations. In addition,
for the year ended December 31, 2023, we expensed $ 10,000 in aggregate associated with annual maintenance fees under the two license agreements
with UC San Diego, which amount is included in research and development expense in the accompanying consolidated statements of operations.

 As of December 31, 2023 and 2022, we have accrued
$ 33,900 and $ 17,700, respectively, in accrued expenses under the license agreements with UC San Diego.

 7. Convertible Notes

 On May 7, 2021, we entered into a convertible
note purchase agreement ("May Note Agreement") with five (5) accredited investors, including three (3) members of our Board
of Directors ("Board") that participated on the same terms as other accredited investors. Pursuant to the Note Agreement,
we received $ 525,003 in proceeds in addition to $ 49,997 in accrued payable to founder that was invested in convertible notes and the Company
issued unsecured convertible promissory notes ("May Convertible Notes") in the aggregate principal amount of $ 575,000.

 On February 18, 2022, we entered into additional
convertible note purchase agreements ("February Note Agreement") with sixteen (16) accredited investors, including five (5)
members of our Board that participated on the same terms as other accredited investors. Pursuant to the February Note Agreement, we received
$ 341,632 in proceeds and issued unsecured convertible promissory notes ("February Convertible Notes") in the aggregate principal
amount of $ 341,632. The February Convertible Notes were issued as part of a convertible note offering authorized by the Company's
Board (the "Convertible Notes Offering") for raising up to $5 million from the issuance of convertible notes through June
30, 2022.

 The May and February Convertible Notes (collectively,
the "Convertible Notes") have no stated maturity date; bear interest at a simple rate equal to eight percent ( 8.0 %) per annum
until converted; and automatically convert into the same equity securities issued for cash in the Qualified Financing (as described below),
or at the option of the holder, into the same equity securities issued for cash in a Smaller Financing (as described below). Interest
on the Convertible Notes is accreted and added to the unpaid principal balance prior to conversion of the Convertible Notes. During the
years ended December 31, 2023 and 2022, the Company recorded non-cash interest expense on the Convertible Notes in the amount of $ 73,333
and $ 69,738, respectively.

 The Convertible Notes will convert into the same
equity securities offered in the Qualified Financing or Smaller Financing ("Conversion Shares"), as described below, at a
conversion price equal to the lower of (i) the product equal to 80% times the lowest per unit purchase price of the equity securities
issued for cash in the Qualified Financing or Smaller Financing, or (ii) $2.377 for the May Convertible Notes ("May Conversion Price")
or $1.00 for the February Convertible Notes ("February Conversion Price"). Pursuant to the February Note Agreement, for each
holder of the May Convertible Notes that purchased a February Convertible Note in the amount of (a) $50,000 or (b) an amount equivalent
to the principal amount of their May Convertible Note, the conversion price of the May Convertible Notes was adjusted to the February
Conversion Price. As of December 31, 2023, the principal amount of Convertible Notes that may be converted at the February Conversion
Price was $866,632. In addition, the conversion price may be reduced or increased proportionately as a result of stock splits, stock dividends,
recapitalizations, reorganizations, and similar transactions. Upon any conversion of the Convertible Notes in connection with a Qualified
Financing or a Smaller Financing, as applicable, the Convertible Notes shall convert immediately prior to the closing thereof, such that
the investors paying cash in such Qualified Financing or Smaller Financing, as applicable, are not diluted by the conversion of the Convertible
Notes.

 F- 18

 Pursuant to the Convertible Notes, a Qualified
Financing represents a single transaction or series of transactions whereby the Company receives aggregate gross proceeds of at least
$5 million from the sale of equity securities following the issuance date (excluding proceeds from the issuance of any future convertible
notes). A Smaller Financing represents any sale of equity securities whereby the aggregate gross proceeds are less than $5 million (excluding
proceeds from the issuance of any future convertible notes).

 In addition, in the event of a corporate transaction
covering the sale of all or substantially all of the Company's assets, or merger or consolidation with or into another entity, or
change in ownership of at least 50% in voting securities of the Company, the holder of the Convertible Note may elect that either: (a)
the Company pay the holder of such Convertible Note an amount equal to the sum of (i) all accrued and unpaid interest due on such Convertible
Note and (ii) one and one-half (1.5) times the outstanding principal balance of such Convertible Note; or (b) such Convertible Note will
convert into that number of conversion shares equal to the quotient obtained by dividing (i) the outstanding principal balance and unpaid
accrued interest of such Convertible Note on the date of conversion by (ii) the May or February Conversion Price, as applicable.

 Pursuant to ASC Topic 835-30, "Imputation
of Interest", the Convertible Notes were initially recorded at their amortized cost of $916,632 and are being accreted to their
redemption value of $ 1,145,790 over the estimated conversion period ending March 31, 2024 using the effective interest method. During
the years ended December 31, 2023 and 2022, the Company recorded $ 15,842 and $ 81,843, respectively, in accretion to redemption value on
the Convertible Notes.

 8. Stockholders'
Equity (Deficit) and Share-Based Compensation

 Stockholders' Equity (Deficit)

 The Company's authorized capital consists
of 100,000,000 shares of common stock, par value $ 0.00001 per share, and 5,000,000 shares of preferred stock, par value $ 0.00001 per share
("Preferred Stock"). We designated 630,000 shares of Series A Convertible Voting Preferred Stock ("Series A Preferred")
and designated and issued 70,000 shares of Series B Convertible Voting Preferred Stock ("Series B Preferred"). As of December
31, 2023 and 2022, there are no shares of Series A Preferred outstanding and 70,000 shares of Series B Preferred outstanding.

 Series B Preferred

 On August 21, 2020, the Company issued 70,000
shares of Series B Preferred (classified as permanent equity), in exchange for 70,000 shares of Class B Common Stock in connection with
the reverse merger in August 2020. Each share of Series B Preferred has a par value of $0.00001 per share, no dividend rate, a stated
value of $6.50 per share, and each share of Series B Preferred initially converts into 11.46837 shares of common stock of the Company
("Series B Conversion Number"). In addition, the Series B Preferred possesses full voting rights, on an as-converted basis,
as the common stock of the Company, as defined in the Series B Certificate of Designation. Furthermore, the Series B Preferred does not
have any mandatory conversion rights and only converts upon written notice from the holder.

 The Series B Preferred also includes certain anti-dilution
rights ("anti-dilution issuance rights"), whereby the holder of Series B Preferred will continue to maintain ownership equal
to 10% of the fully diluted shares of common stock outstanding, including for such purposes all other convertible securities outstanding
and reserved for issuance except equity awards issued and outstanding and reserved for issuance under a board approved equity compensation
plan reserving for issuance no more than ten percent (10%) of the outstanding common stock of the Company then outstanding, until the
Capital Threshold is met. The anti-dilution issuance rights meet the definition of a derivative instrument under FASB's ASC Topic
815 (see Note 3). As of December 31, 2023, the $1 million dollar Capital Threshold was achieved and therefore, there is no remaining derivative
liability (see Note 6).

 F- 19

 In the event of any Liquidation Event, the Holders
of Series B Preferred shall be entitled to receive, prior and in preference to any distribution of any of the assets or surplus funds
of the Company to the holders of common stock, an amount per share in cash equal to the greater of (x) the stated value of $6.50 for each
share of Series B Preferred then held by the holder or (y) the amount payable per share of common stock which such holder of Series B
Preferred would have received if such Holder had converted to common stock immediately prior to the Liquidation Event.

 Share-Based Compensation

 2020 Omnibus Incentive Plan

 On October 21, 2020, we adopted our 2020 Omnibus
Incentive Plan (the "2020 Plan") and on October 22, 2020, the 2020 Plan was approved by our stockholders. The 2020 Plan was
adopted to promote our long-term success and the creation of stockholder value by motivating participants, through equity incentive awards,
to achieve long-term success in our business. The 2020 Plan permits the discretionary award of stock options, restricted stock, RSUs,
and other equity awards to selected participants. On October 21, 2021, the first anniversary date from the adoption date of the 2020 Plan,
the number of shares of common stock reserved for issuance under the 2020 Plan increased to 20% of the fully diluted shares of common
stock outstanding, including shares of common stock reserved for issuance under convertible securities. As of December 31, 2023, we have
reserved 1,661,966 shares of common stock for issuance under the 2020 Plan, of which 541,957 were subject to outstanding RSUs and 1,105,965
shares were available for future grants of share-based awards.

 The cost of all share-based awards will be recognized
in the consolidated financial statements based on the fair value of the awards. The fair value of stock option awards will be determined
using the Black-Scholes valuation model on the date of grant. The fair value of restricted stock awards and RSUs will be equal to the
closing market price of our common stock on the date of grant. The Company will generally recognize share-based compensation expense
over the period of vesting or period that services will be provided for all time-based awards. Share-based compensation expense for the
years ended December 31, 2023 and 2022 was comprised of the following:

 We have federal and state net operating loss carryforwards
available to offset future taxable income of approximately $ 3,939,000 and $ 2,244,000 at December 31, 2023, respectively, of which approximately
$ 2,554,000 and $ 468,000, respectively, are subject to a limitation under IRS Section 382. Approximately $ 3,562,000 of the federal net
operating losses can be carried forward indefinitely with $ 2,273,000 subject to a limitation under IRS Section 382. The remaining $281,000
of federal net operating losses will expire from 2025 through 2036. The state net operating losses will expire from 2028 through 2042.

 We follow authoritative guidance which defines
criteria that an individual tax position must meet for any part of the benefit of that position to be recognized in a company's
financial statements and also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim
periods, disclosure and transition. Interest and penalties, if any, related to unrecognized tax benefits are recorded in income tax expense.
Interest and penalties relating to underpayment of income taxes are recorded in general and administrative expense. As of December 31,
2023, we are subject to U.S. Federal income tax examinations for the tax years May 31, 2018 through December 31, 2023, and we are subject
to state and local income tax examinations for the tax years May 31, 2020 through December 31, 2023 due to the carryover of net operating
losses.

 We have no liability relating to unrecognized
tax benefits under the authoritative guidance for the year ended December 31, 2023 and 2022.

 Our continuing practice is to recognize accrued
interest and penalties related to unrecognized tax benefits as a component of tax expense. We do not expect our unrecognized tax benefits
to change significantly over the next twelve months.

 10. Commitments and Contingencies

 Legal Matters

 While the Company is not involved in any litigation
as of December 31, 2023, the Company may be involved in various lawsuits and claims arising in the ordinary course of business, including
actions with respect to intellectual property, employment, and contractual matters. Any litigation could have a material adverse effect
on the Company's business, financial condition, results of operations, and/or cash flows in the period in which the unfavorable
outcome occurs or becomes probable, and potentially in future periods.

 Indemnification

 We have made certain guarantees and indemnities,
under which we may be required to make payments to a guaranteed or indemnified party. We indemnify our directors, officers, employees,
and agents to the maximum extent permitted under the laws of the State of Delaware. The duration of the guarantees and indemnities varies,
and in many cases is indefinite. These guarantees and indemnities do not provide for any limitation of the maximum potential future payments
we could be obligated to make. Historically, we have not been obligated to make any payments for these obligations and no liabilities
have been recorded for these guarantees and indemnities in the accompanying consolidated balance sheets.

 Escrow Shares

 On August 31, 2009, we gave notice to the
former shareholders of Crossflo and Union Bank of California (the "Escrow Agent") under Section 2.5 of the Agreement and
Plan of Merger between us and Crossflo (the "Agreement"), outlining damages incurred by us in conjunction with the
acquisition of Crossflo, and seeking the return of 5,690 shares of our common stock held by the Escrow Agent. Subsequently, former
shareholders of Crossflo, representing a majority of the escrowed shares responded in protest to our claim, delaying the release of
the escrowed shares until a formal resolution is reached. In the event we fail to prevail in our claim against the escrowed
shares, we may be obligated to deposit into escrow approximately $256,000 of cash consideration due to the decline in our average
stock price over the one-year escrow period calculated in accordance with Section 2.5 of the Agreement. We have evaluated the
potential for loss regarding our claim and believe that it is probable that the resolution of this issue will not result in a
material obligation to the Company, although there is no assurance of this. Accordingly, we have not recorded any liability for this
matter.

 Operating Lease

 We have no lease obligations as of December 31,
2023 and there was no rent expense for the years ended December 31, 2023 and 2022. Employees are working from home offices at no cost
to the Company.

 11. Related
Parties

 During April 2021, we entered into consulting
agreements (retroactive to September 1, 2020) with Nicole Steinmetz, Ph. D., former acting Chief Scientific Officer and former member of
the Board of Directors, Jonathan Pokorski, Ph. D. (Dr. Steinmetz's spouse), and Steve Fiering, Ph. D., each a co-founder of the company
acquired in the reverse merger and greater than 5% shareholder of the Company ("Related Parties"), for their scientific contributions
towards advancing the technology platforms. On May 2, 2023, Dr. Steinmetz resigned from the Board of Directors and her role as acting
Chief Scientific Officer.

 F- 23

 During the year ended December 31, 2023, we incurred
related party consulting expenses for Dr. Steinmetz, Dr. Pokorski, and Dr. Fiering in the aggregate amount of $ 20,000, $ 10,000 and $ 500,
respectively, included in research and development expenses in the accompanying consolidated financial statements. Pursuant to the consulting
agreements, Dr. Steinmetz, Dr. Pokorski, and Dr. Fiering are initially paid 15% of their monthly amounts up and until the Company is able
to raise at least $4 million in new funding. In exchange for the deferral of consulting payments, the Company agreed to grant each of
the Related Parties RSU's with a fair market value equal to 20% of their deferred cash compensation as of the closing date of the
financing (the "20% Deferral"). The number of RSU's to be granted will be calculated based on the closing price of the
Company's common stock on the closing date of the financing and will vest one-year from the date of grant. There was no share-based
compensation expense recorded for the years ended December 31, 2023 and 2022 pertaining to the 20% Deferral as the terms are unknown and
are based on a future performance trigger. As of December 31, 2023 and 2022, we have accrued $ 264,375 and $ 238,000, respectively, in accrued
consulting fees provided by the Related Parties, which amounts are included in accrued consulting in the accompanying consolidated balance
sheets.

 In addition, on May 7, 2021, we entered into convertible
note purchase agreements with five (5) accredited investors, including three (3) members of our Board of Directors that participated on
the same terms as other accredited investors, in the aggregate principal amount of $575,000. Of such amount, the three members of our
Board of Directors invested $225,000 in aggregate (see Note 7).

 Moreover, on February 18, 2022, we entered into
convertible note purchase agreements with sixteen (16) accredited investors, including five (5) members of our Board that participated
on the same terms as other accredited investors, in the aggregate principal amount of $341,632. Of such amount, four members of our Board
and one former member of our Board invested $155,000 in aggregate (see Note 7).

 12. Subsequent
Events

 We have evaluated subsequent events after the
consolidated balance sheet date and through the filing date of this Report, and based on our evaluation, management has determined that
no other subsequent events have occurred that would require recognition in the accompanying consolidated financial statements or disclosure
in the notes thereto other than as disclosed herein and in the accompanying notes.

 On May 4, 2022, we entered into a License Agreement
with CWRU (see Note 6). Pursuant to the License Agreement, we agreed to reimburse CWRU for all intellectual property fees incurred since
inception of the portfolio through the date of the License Agreement in the amount of approximately $303,000 payable in four (4) equal
quarterly installments beginning upon the sooner of (i) August 31, 2022 or (ii) upon the Company closing a financing in the amount of
$5 million or more. Due to our limited cash position, as of December 31, 2023, we have not paid any amounts owed to CWRU. While CWRU has
previously provided us additional time to pay amounts owed under the License Agreement beyond the initial August 31, 2022 due date, on
March 22, 2024, we received a letter of termination from CWRU terminating our License Agreement effective immediately due to our financial
default. In addition, CRWU did not relieve us of any amounts past due under the License Agreement and requested payment in full. As of
December 31, 2023, we have accrued $406,973 in accrued patent fees under the License Agreement. Due to our limited cash position, we do
not have sufficient capital to pay amounts owed under the License Agreement. We are evaluating strategic options for the Company, which
could include a possible merger, business combination, wind-down, liquidation and dissolution or other strategic transaction.
