Narrative
to Summary Compensation Table



All

Offer
Letter Amendments



In
connection with the Company’s previously announced plan to reduce operating expenses, on October 15, 2019, the Company and
each of Andrew Ritter, John Beck and Ira Ritter entered into an amendment to their respective offer letters (the
“Offer Letter Amendments”).



Pursuant
to the terms of the Offer Letter Amendments, each of the executive officers agreed to defer a portion of his annual base salary
(the “Deferred Amounts”), as set forth below, until such time as the board of directors, in its sole discretion, decides
to pay the Deferred Amounts (or any portion of the Deferred Amounts) to the executive officers, if ever.



|Name of Executive Officer |  | Deferred Amount |       
|------------------------- |  | --------------- | ------
|Andrew J. Ritter          |  | $               | 70,200
|John W. Beck              |  | $               | 33,000
|Ira E. Ritter             |  | $               | 53,820



The
board of directors has since determined that the Deferred Amounts will be paid to the executive officers upon the closing of the
proposed merger between the Company and Qualigen, Inc.



2015
Equity Incentive Plan



On
June 15, 2015, our board of directors approved the 2015 Equity Incentive Plan (the “2015 Plan”), and on June 17, 2015,
the 2015 Plan was approved by our stockholders. The 2015 Equity Incentive Plan was subsequently amended by the stockholders of
the Company on June 3, 2016, June 2, 2017 and August 24, 2017.



The
purposes of the 2015 Plan are to optimize the profitability and growth of the Company through long-term incentives that are consistent
with the Company’s objectives and that link the interests of award recipients (“Grantees”), to those of the
Company’s stockholders; to give award recipients an incentive for excellence in individual performance; to promote teamwork
among Grantees; and to give the Company flexibility in attracting and retaining key employees, directors and consultants.



Selected
employees, officers and directors of the Company or any subsidiary, and consultants, advisors and independent service providers
to the Company and any subsidiary who qualify as a “consultant” under the applicable rules of the SEC for registration
of shares on a Form S-8 registration statement, are eligible to receive awards under the 2015 Plan. The plan administrator may
also grant awards to individuals in connection with hiring, retention or otherwise before the date the individual first performs
services for the Company or any subsidiary; provided, however, that those awards will not become vested or exercisable before
the date the individual first performs services for the Company or any subsidiary.



7







The
number of shares of common stock that we may issue pursuant to awards under the 2015 Plan is (i) 2,750,000 plus (ii) any shares
which were available for grant under the 2008 Stock Plan or the 2009 Stock Plan (collectively, the “Prior Plans”),
on the effective date of the 2015 Plan or are subject to awards under the Prior Plans which, after the effective date of the 2015
Plan, are forfeited or lapse unexercised or are settled in cash and are not issued under the Prior Plans. No more than 2,750,000
shares of common stock may be issued pursuant to incentive stock options intended to qualify under Section 422 of the Internal
Revenue Code (the “Code”). No awards may be granted under any Prior Plan; however, any awards granted under any Prior
Plan that were outstanding as of the effective date of the 2015 Plan continue to be subject to the terms and conditions of such
Prior Plan.



The
2015 Plan provides for grants of stock options (including incentive stock options qualifying under Section 422 of the Code and
nonstatutory stock options), restricted stock awards, stock appreciation rights, restricted stock units, performance awards, other
stock-based awards or any combination of the foregoing.



Performance-Based
Restricted Stock Units Granted in 2018



On
June 26, 2018, our Compensation Committee granted performance-based restricted stock unit awards to each of Andrew J. Ritter (650,000
performance-based restricted stock units), Ira E. Ritter (300,000 performance-based restricted stock units) and John W. Beck (150,000
performance-based restricted stock units). The awards were subject to vesting criteria relating to the achievement of three specific
performance goals established by the Compensation Committee. Each performance restricted stock unit represented a contingent right
to receive one share of common stock, subject to the vesting conditions being satisfied. The terms of these awards provided as
follows:



| | ● | If
    the first performance goal was achieved by the target date established by the Compensation Committee, then 100% of the target
    restricted stock units allocated to the first goal (i.e., 40% of the total target restricted stock units granted to
    the executive officer) would vest and the underlying shares of common stock would be issued, and if the first goal was achieved
    by an earlier date established by the Compensation Committee, then 125% of the target restricted stock units allocated to
    the first goal would vest and the underlying shares of common stock would be issued;

| | ● | If
    the second performance goal was achieved by the target date established by the Compensation Committee with respect to this
    goal, then 100% of the target restricted stock units allocated to the second goal (i.e., 40% of the total target restricted
    stock units granted to the executive officer) would vest and the underlying shares of common stock would be issued, and if
    the second goal was achieved by an earlier date established by the Compensation Committee, then 125% of the target restricted
    stock units allocated to the second goal would vest and the underlying shares of common stock would be issued; and
| |   |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
| | ● | If
    the third performance goal was achieved by the target date established by the Compensation Committee with respect to this
    goal, then 100% of the target restricted stock units allocated to the third goal (i.e., 20% of the total target restricted
    stock units granted to the executive officer) would vest and the underlying shares of common stock would be issued, and if
    the third goal was achieved by an earlier date established by the Compensation Committee, then 125% of the target restricted
    stock units allocated to the third goal would vest and the underlying shares of common stock would be issued.        



On
January 15, 2020, our board of directors cancelled these awards.

Payments
Due Upon Termination of Employment or a Change in Control



Executive
Severance & Change in Control Agreements



We
have entered into Executive Severance & Change in Control Agreements (the “Severance Agreements”), with each of
our named executive officers. The Severance Agreements provide that if we terminate the executive’s employment without Cause,
or the executive terminates his employment for Good Reason, the executive will be entitled to: (i) the Accrued Obligations; (ii)
an amount equal to the sum of twelve (12) months of base salary for Andrew and Ira Ritter and six (6) months of base salary for
John Beck, as in effect immediately prior to the termination date; (iii) medical, dental benefits provided by the Company to the
executive and his spouse and dependents at least equal to the levels of benefits provided to other similarly situated active employees
of the Company and its subsidiaries until the earlier of (a) the twelve (12) month anniversary of the date of termination or (b)
the date that the executive becomes covered under a subsequent employer’s medical and dental plans; and (iv) acceleration
of vesting of all equity and equity-based awards.



Pursuant
to the terms of the Severance Agreements, in the event that within one (1) month prior to or the twelve (12) months following
a Change in Control, the Company terminates the executive’s employment without Cause, or the executive terminates his employment
for Good Reason, then, in lieu of the payments and benefits otherwise due to the executive in the preceding paragraph, the executive
will be entitled to: (i) the Accrued Obligations; (ii) an amount equal to the sum of twelve (12) months of base salary for Andrew
and Ira Ritter and six (6) months of base salary for John Beck, as in effect on the date of termination or the date of the Change
in Control, whichever is greater; (iii) medical, dental benefits provided by the Company to the executive and his spouse and dependents
at least equal to the level of benefits provided to other similarly situated active employees of the Company and its subsidiaries
until the earlier of (a) the twelve (12) month anniversary of the date of termination or (b) the date that the executive becomes
covered under a subsequent employer’s medical and dental plans; and (iv) acceleration of vesting of all equity and equity-based
awards.



In
the event the executive’s employment is terminated by him without Good Reason, by the Company for Cause or due to the executive’s
death or disability, the executive and/or his estate or beneficiaries will be solely entitled to the Accrued Obligations.



The
executive’s entitlement to the payments (other than the Accrued Obligations) and benefits described above is expressly contingent
upon him providing the Company with a signed release satisfactory to the Company.



For
purposes of the Severance Agreements:



“Accrued
Obligations” means (i) earned but unpaid base salary through the date of termination; (ii) payment of any annual, long-term,
or other incentive award which relates to a completed fiscal year or performance period, as applicable, and is payable (but not
yet paid) on or before the date of termination; (iii) a lump-sum payment in respect of accrued but unused vacation days at the
executive’s per-business-day base salary rate in effect as of the date of termination; and (iv) any unpaid expense or reimbursements
due pursuant to Company expense reimbursement policy.



10







“Cause”
means a finding by the Company that the executive has (i) been convicted of a felony or crime involving moral turpitude; (ii)
disclosed trade secrets or confidential information of the Company (or any parent or subsidiary) to persons not entitled to receive
such information; (iii) engaged in conduct in connection with the executive’s employment or service to the Company (or any
parent or subsidiary), that has, or could reasonably be expected to result in, material injury to the business or reputation of
the Company (or any parent or subsidiary), including, without limitation, act(s) of fraud, embezzlement, misappropriation and
breach of fiduciary duty; (iv) violated the operating and ethics policies of the Company (or any parent or subsidiary) in any
material way, including, but not limited to those relating to sexual harassment and the disclosure or misuse of confidential information;
(v) engaged in willful and continued negligence in the performance of the duties assigned to the executive by the Company, after
the executive has received notice of and failed to cure such negligence; or (vi) breached any material provision of any agreement
between the executive and the Company (or any parent or subsidiary), including, without limitation, any confidentiality agreement.



“Change
in Control” means the occurrence of any of the following events:



| | (i)   | Any
    “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes a “beneficial owner”
    (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more
    than 50% of the voting power of the then outstanding securities of the Company; provided that a Change of Control will not
    be deemed to occur as a result of a change of ownership resulting from the death of a shareholder, and a Change of Control
    will not be deemed to occur as a result of a transaction in which the Company becomes a subsidiary of another corporation
    and in which the shareholders of the Company, immediately prior to the transaction, will beneficially own, immediately after
    the transaction, shares entitling such shareholders to more than 50% of all votes to which all shareholders of the parent
    corporation would be entitled in the election of directors (without consideration of the rights of any class of stock to elect
    directors by a separate class vote);

| | (iii) | The
    consummation of  (A) a merger or consolidation of the Company with another corporation where the shareholders of the
    Company, immediately prior to the merger or consolidation, will not beneficially own, immediately after the merger or consolidation,
    shares entitling such shareholders to more than 50% of all votes to which all shareholders of the surviving corporation would
    be entitled in the election of directors (without consideration of the rights of any class of stock to elect directors by
    a separate class vote); (B) a sale or other disposition of all or substantially all of the assets of the Company; or (C) a

“Good
Reason” means, without the executive’s express written consent, the occurrence of any one or more of the following:
(i) a substantial and material diminution in the executive’s duties or responsibilities; (ii) a material reduction in the
executive’s Base Salary; or (iii) the relocation of the executive’s principal place of employment to a location that
is more than 50 miles from the prior location.



A
termination of employment by the executive for Good Reason will be effectuated by giving the Company written notice, or Notice
of Termination for Good Reason, not later than 90 days following the occurrence of the circumstance that constitutes Good Reason,
setting forth in reasonable detail the specific conduct of the Company that constitutes Good Reason and the specific provision(s)
of this Agreement on which the executive relied. The Company will be entitled, during the 30-day period following receipt of a
Notice of Termination for Good Reason, to cure the circumstances that gave rise to Good Reason, provided that the Company shall
be entitled to waive its right to cure or reduce the cure period by delivery of written notice to that effect to the executive
(such 30-day or shorter period, the “Cure Period”). If, during the Cure Period, such circumstance is remedied, the
executive will not be permitted to terminate his employment for Good Reason as a result of such circumstance. If, at the end of
the Cure Period, the circumstance that constitutes Good Reason has not been remedied, the executive will terminate employment
for Good Reason on the date of expiration of the Cure Period.



2008
Stock Plan



The
2008 Stock Plan provides that in the event of a merger or a Change in Control (as defined below), each outstanding award will
be treated as the administrator determines, including, without limitation, that each award be assumed or an equivalent award be
substituted by the successor corporation or a parent or subsidiary of the successor corporation. In the event of a Change in Control
in which the successor corporation does not assume or substitute for the award, awards outstanding under the 2008 Stock Plan will
become fully vested and exercisable, including shares as to which such award would not otherwise be vested or exercisable, and
all restrictions on outstanding restricted stock awards will lapse.

For
purposes of the 2008 Stock Plan, “Change in Control” means the occurrence of any of the following events:



| | (i)   | A
    change in the ownership of the Company which occurs on the date that any one person, or more than one person acting as a group
    (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person,
    constitutes more than 50% of the total voting power of the stock of the Company, except that any change in the ownership of
    the stock of the Company as a result of a private financing of the Company that is approved by the board of directors will
    not be considered a Change in Control; or

| | (iii) | A
    change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any person acquires
    (or has acquired during the twelve month period ending on the date of the most recent acquisition by such person or persons)

    value of all of the assets of the Company immediately prior to such acquisition or acquisitions.                                                              



2015
Equity Incentive Plan



The
2015 Plan provides that notwithstanding any other provision of the 2015 Plan, in the event of a Change in Control (as defined
below), unless otherwise determined by the plan administrator, each outstanding award under the plan will be assumed or an equivalent
award substituted by the successor corporation or a parent or subsidiary of the successor corporation. In the event that, or to
the extent that, the successor corporation in a Change in Control refuses to assume or substitute for the award, or if the plan
administrator determines that such assumption or substitution is not desirable or is only desirable for a portion of any outstanding
award, then the plan administrator may take any or all of the following actions: (i) determine that an outstanding award will
accelerate and become exercisable, or determine that the restrictions and conditions on an outstanding award will lapse, in whole
or in part, as applicable, upon the Change of Control or upon such other event as the plan administrator determines; (ii) require
that a Grantee surrender his or her outstanding award, or any portion of such outstanding award, in exchange for a payment by
the Company, in cash or stock, as determined by the plan administrator, in an amount equal to the fair market value of the vested
portion of the award (with respect to options or stock appreciation rights, or other similar appreciation value awards, such value
shall be determined by the amount by which the then fair market value of the shares subject to the Grantee’s unexercised
award exceeds the any applicable exercise price or other grant price or base value or the award); or (iii) after giving the Grantee
an opportunity to exercise the vested portion of his or her outstanding award, terminate any or all unexercised portion of the
award at such time as the plan administrator deems appropriate. Such surrender or termination will take place as of the date of
the Change of Control or such other date as the plan administrator may specify.



For
purposes of the 2015 Plan, “Change in Control” means the occurrence of any of the following events:



| | (i)  | A
    change in our ownership which occurs on the date that any one person, or more than one person acting as a group, or Person,
    acquires ownership of our stock that, together with the stock held by such Person, constitutes more than 50% of the total
    voting power of our stock, except that any change in the ownership of our stock as a result of a private financing that is
    approved by our board of directors will not be considered a Change in Control; or

    occurs on the date that a majority of members of our board of directors is replaced during any twelve (12) month period by
    directors whose appointment or election is not endorsed by a majority of the members of our board of directors prior to the
    date of the appointment or election. For purposes of this paragraph (ii), if any Person is considered to be in effective control
    of our company, the acquisition of additional control of our company by the same Person will not be considered a Change in
    Control; or



| | (iii) | A
    change in the ownership of a substantial portion of our assets which occurs on the date that any Person acquires (or has acquired
    during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) assets from
    us that have a total gross fair market value equal to or more than 50% of the total gross fair market value of all of our
    assets immediately prior to such acquisition or acquisitions. For purposes of this paragraph (iii), gross fair market value
    means the value of our assets, or the value of the assets being disposed of, determined without regard to any liabilities
    associated with such assets.

We
utilize the Black-Scholes option-pricing model to value awards. Key valuation assumptions include:



| | ● | Expected
    dividend yield. The expected dividend is assumed to be zero as we have never paid dividends and have no current plans
    to pay any dividends on our common stock.

| | ● | Expected
    stock-price volatility. As our common stock only recently became publicly traded, the expected volatility is derived from
    the average historical volatilities of publicly traded companies within our industry that we consider to be comparable to
    our business over a period approximately equal to the expected term.

| | ● | Expected
    term. The expected term represents the period that the stock-based awards are expected to be outstanding. Our historical
    share option exercise experience does not provide a reasonable basis upon which to estimate an expected term because of a
    lack of sufficient data. Therefore, we estimate the expected term by using the simplified method provided by the SEC. The
    simplified method calculates the expected term as the average of the time-to-vesting and the contractual life of the options.



In
addition to the assumptions used in the Black-Scholes option-pricing model, we also estimate a forfeiture rate to calculate the
stock-based compensation for our equity awards. We will continue to use judgment in evaluating the expected volatility, expected
terms and forfeiture rates utilized for our stock-based compensation calculations on a prospective basis.

The
number of shares beneficially owned by each entity, person, director or executive officer is determined under the rules of the
SEC and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rules, beneficial

common stock that may be acquired by an individual or group within 60 days of April 10, 2020, pursuant to the exercise of options,
warrants or other rights, are deemed to be outstanding for the purpose of computing the percentage ownership of such individual
or group, but are not deemed to be outstanding for the purpose of computing the percentage ownership of Ritter’s common
stock of any other person shown in the table.



The
percentage of beneficial ownership is based on 46,152,960 shares of Ritter common stock outstanding on April 10, 2020.



Subject

13. Certain Relationships and Related Transactions, and Director Independence.



Certain
Relationships and Related Party Transactions



Our
Audit Committee is responsible for reviewing, approving and overseeing any transaction between the Company and its directors,
director nominees, executive officers, greater than 5% beneficial owners, and each of their respective immediate family members,
where the amount involved exceeds the lesser of (i) $120,000 and (ii) one percent (1%) of the average of our total assets at year-end
for the prior two fiscal years. Since January 1, 2018, there have been no such transactions.



Director
Independence



Under
Nasdaq’s continued listing requirements, a majority of a listed company’s board of directors must be comprised of
independent directors, subject to certain exceptions. In addition, Nasdaq’s continued listing requirements require that,
subject to certain exceptions, each member of a listed company’s audit, compensation and governance and nominating committees
must be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange
Act. Under Nasdaq’s continued listing requirements, a director will only qualify as an “independent director”
if, in the opinion of that company’s board of directors, such person does not have a relationship that would interfere with
the exercise of independent judgment in carrying out the responsibilities of a director.



Based
upon information requested from and provided by each director concerning their background, employment and affiliations, including
family relationships, our board of directors determined that each of Messrs. Doyle, Foehr and Maier and Dr. Merino are independent
under the applicable rules and regulations of Nasdaq. In making such determinations, the board of directors considered the relationships
that each such non-employee director has with our company and all other facts and circumstances the board of directors deemed
relevant in determining their independence.

The
Audit Committee has adopted a formal policy on auditor independence requiring the advance approval by the Audit Committee of all
audit and non-audit services provided by our independent registered public accounting firm. In determining whether to approve
any services by our independent registered public accounting firm, the Audit Committee reviews the services and the estimated
fees, and considers whether approval of the proposed services will have a detrimental impact on the auditor’s independence.
On an annual basis, our management reports to the Audit Committee all audit services performed during the previous 12 months and
all fees billed by our independent registered public accounting firm for such services.



In
fiscal 2019 and 2018, all audit services and the corresponding fees were approved by our board of directors.

REPORT
OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM





To
the Board of Directors and Stockholders of Ritter Pharmaceuticals, Inc.



Opinion
on the Financial Statements



We
have audited the accompanying balance sheets of Ritter Pharmaceuticals, Inc. (the “Company”) as of December 31, 2019
and 2018, and the related statements of operations and comprehensive loss, changes in stockholders’ equity, and cash flows
for each of the two years in the period ended December 31, 2019, and the related notes (collectively referred to as the “financial
statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position
of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the two years
in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.



Going
Concern Uncertainty



The
accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed
in Note 2 to the financial statements, the Company has incurred recurring operating losses and is dependent on additional financing
to fund operations. These conditions raise substantial doubt about the Company’s ability to continue as a going concern.
Management’s plans in regard to these matters are described in Note 2 to the financial statements. The financial statements
do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the
amounts and classification of liabilities that may result from the outcome of this uncertainty.



Basis
for Opinion



These
financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on
the Company’s financial statements based on our 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 audits
to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error
or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial
reporting. As part of our 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 financial statements, whether due to
error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence
regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles
used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.
We believe that our audits provide a reasonable basis for our opinion.



We
have served as the Company's auditor since 2014.

RITTER
PHARMACEUTICALS, INC.

NOTES
TO FINANCIAL STATEMENTS



NOTE
1 — ORGANIZATION AND PRINCIPAL ACTIVITIES





Since
its inception,Ritter Pharmaceuticals, Inc. (“Ritter”
or the “Company”) has focused on the development of therapeutic products that modulate the gut microbiome
to treat gastrointestinal diseases. The Company’s only product candidate, RP-G28, is an orally administered, high
purity galacto-oligosaccharide (“GOS”), for the treatment of lactose intolerance (“LI”), a condition
that affects millions of people worldwide. RP-G28 is designed to selectively stimulate the growth of lactose-metabolizing bacteria
in the colon, thereby effectively adapting the gut microbiome to assist in digesting lactose (the sugar found in milk) that reaches
the large intestine.







Ritter
was formed as a Nevada limited liability company on March 29, 2004 under the name Ritter Natural Sciences, LLC. Its first prototype
LI product, LactagenTM, was an alternative LI treatment method with a mechanism of action similar to RP-G28. In 2004, clinical
testing was conducted with Lactagen, which included a 61-subject double-blind placebo controlled clinical trial. The results were
published in the Federation of American Societies for Experimental Biology in May 2005.



In
early 2008, the Company initiated a prescription drug development program by developing RP-G28, an improved, second-generation
version of Lactagen, based on the belief that if it was successful in gaining approval from the U.S. Food and Drug Administration
(“FDA”), it would be able to make stronger claims of both efficacy and safety, garner more medical community support
and reach a wider market in the effort to treat LI.



In
November 2010, Ritter was awarded a grant from the United States government’s Health Care Bill program, the Qualifying Therapeutic
Discovery Project, to help fund the development of RP-G28. This grant program provides support for innovative projects that are
determined by the U.S. Department of Health and Human Services to have reasonable potential to result in new therapies that treat
areas of unmet medical need and/or prevent, detect or treat chronic or acute diseases and conditions.



In
November 2011, the Company completed a Phase 2a clinical trial of RP-G28. Positive trends were seen when the entire per protocol
study population was analyzed, including some statistically significant subgroup. The combined data demonstrated proof of concept
and suggested that RP-G28 administration produced a positive therapeutic effect. RP-G28 was also well tolerated with no significant
study-drug related adverse effects.



In
October 2016, the Company completed a Phase 2b multi-center, randomized, double-blind, placebo-controlled, parallel group trial
of RP-G28. Topline results of the trial were announced in March 2017. Results showed a clinically meaningful benefit to subjects
in the reduction of LI symptoms across a variety of outcome measures. The majority of analyses showed positive outcome measures
and the robustness of the data point to a clear drug effect. Treatment patients not only reported meaningful reduced symptoms,
but also 30 days after taking the treatment, patients reported adequate relief from LI symptoms and satisfaction with the results
of the treatment, with RP-G28 preventing or treating their LI symptoms. Greater milk and dairy product consumption was also reported
by patients.





In August
2017, the Company held an End-of-Phase 2 meeting with the FDA’s Division of Gastroenterology and Inborn Errors Products.
The purpose of the meeting was to obtain the FDA’s feedback on its Phase 3 program. The Company reached general consensus
with the FDA on certain elements of its Phase 3 program and clear guidance and recommendations on many necessary components of
its Phase 3 program; including the clinical, non-clinical, and chemistry, manufacturing and controls (“CMC”) requirements
needed to support a new drug application (“NDA”) submission.



In
June 2018, the Company initiated the first pivotal Phase 3 clinical trial of RP-G28. Called “Liberatus”, this study
was to determine the efficacy, safety and tolerability of RP-G28 to treat LI when compared to placebo. The study was a multicenter,
randomized, double-blind, placebo-controlled, parallel-group study conducted in the United States. Trial enrollment exceeded expectations,
concluding with approximately 557 subjects randomized. More than 30 U.S. sites participated in the study. The protocol design
included a 2-week screening period that included one week of study drug administration, a randomized 30-day study drug treatment
period and a 90-day “real world experience” period to assess study drug response and durability of effect after treatment
as patients consumed their normal diets including dairy products. The primary endpoint of the study was the mean change in LI
symptom composite score 30-days post-treatment compared to baseline. Secondary endpoints were to examine the safety, tolerability
and meaningfulness of treatment benefit with RP-G28 and the durability of effect of treatment with RP-G28 on reduction of LI symptoms
after real-world lactose exposure. The study utilized the prior validated symptom assessment measure and patient questionnaires
to capture relevant outcomes. In addition, risk-based data review was used to monitor and assess potential protocol deviations
and site quality indicators.





F-6







The
Company completed enrollment of the Liberatus Phase 3 clinical trial of RP-G28 in March 2019 and last patient visit in July 2019.
In September 2019, the Company announced that its Phase 3 clinical trial of RP-G28 for LI failed to demonstrate statistical significance
in its pre-specified primary and secondary endpoints.





On October
7, 2019, the Company announced publicly that it had engaged AGP as a financial advisor to explore and evaluate potential strategic
alternatives, as it continued to analyze the results of the trial to better understand the data and clinical outcome to assess
a path forward for RP-G28. All further development efforts for RP-G28 have been suspended, until such time as the Company determines
a path forward.



On
January 15, 2020, Ritter entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Qualigen Inc.
(“Qualigen”), pursuant to which a wholly owned Company Merger Sub will merge with and into Qualigen, with Qualigen
surviving as a wholly owned subsidiary of Ritter Pharmaceuticals, Inc.





If
the merger is consummated, the combined company does not intend to continue the clinical development of RP-G28. Pursuant to the
terms of the Merger Agreement, at the Effective Time (as defined in the Merger Agreement), Ritter and John Beck, the Company’s
Chief Financial Officer, acting as the initial contingent value right (“CVR”) holders’ representative and in
his capacity as a consultant to Ritter, will enter into a Contingent Value Rights Agreement (the “CVR Agreement”),
pursuant to which, each stockholder of record as of immediately prior to the Effective Time (after giving effect to the exercise
of any outstanding stock options or warrants and the conversion of any outstanding preferred stock, but not to be adjusted for
any reverse split to be effected in connection with the merger) will receive one CVR for each share of capital stock held by such
stockholder, entitling the holder to receive the net proceeds, if any, from any sale, license, transfer, spin-off or other monetizing
event of all or any part of our current business or all or any part of our intellectual property or technology (a “Legacy
Monetization”) that is entered into during the period beginning on the date the Merger Agreement was signed and ending on
the third anniversary of the closing date of the merger. Under the CVR Agreement, the combined company agreed to commit up to
$350,000 (subject to reduction pursuant to the terms of the Merger Agreement) for certain expenses to be incurred by us in pursuing
and closing any Legacy Monetization. The CVRs will not be transferable by the holders of CVRs (“CVR Holders”), except
in certain limited circumstances, will not be certificated or evidenced by any instrument, will not accrue interest and will not
be registered with the Securities and Exchange Commission (the “SEC”) or listed for trading on any exchange. The CVRs
will terminate on the tenth anniversary of the Effective Time (the “CVR Termination Date”). No payments with respect
to the CVRs will be payable in respect of any Legacy Monetization proceeds actually received after the CVR Termination Date by
us. From and after the CVR Termination Date, any further proceeds received by us arising from any Legacy Monetization will be
retained by Ritter and will not be distributed to the CVR Holders.



The
Company may not be successful in completing the merger. If the merger is not completed, Ritter may seek to pursue the development
and commercialization of RP-G28 as either a prescription drug, OTC product or dietary supplement for the consumer healthcare industry,
which would, in any case, require significant additional funding. If Ritter is unable to obtain funding for the development of
RP-G28, whether through potential collaborative, partnering or other strategic arrangements or otherwise, it will likely be required
to cease operations





The
Company currently operates in one business segment focusing on the potential future development and commercialization of
RP-G28. The Company is not organized by market and is managed and operated as one business. A single management team reports to
the chief operating decision maker, the Chief Executive Officer. The Company does not currently operate any separate lines of
business or separate business entities.



NOTE
2 — BASIS OF PRESENTATION





The accompanying
financial statements have been prepared in accordance with GAAP and include all adjustments necessary for the fair presentation
of the Company’s financial position for the periods presented.



Going
Concern and Liquidity



The accompanying financial statements
have been prepared assuming the Company will continue as a going concern, which contemplates, among other things, the realization
of assets and satisfaction of liabilities in the normal course of business. The Company has not generated any product revenue
and has not achieved profitable operations. The Company had net losses of approximately $10.1 million and $16.9 million for the
years ended December 31, 2019 and 2018, respectively, and had net cash used in operating activities of approximately $14.5 million
and $13.3 million, for the years ended December 31, 2019 and 2018, respectively. At December 31, 2019, the Company had working
capital of approximately $0.5 million, an accumulated deficit of approximately $80.3 million, cash and cash equivalents of approximately
$1.7 million. There is no assurance that profitable operations will ever be achieved, and, if achieved, could be sustained on
a continuing basis. In addition, development activities, clinical and pre-clinical testing, and commercialization of the Company’s
products will require significant financing. If the Plan of Merger is not successful, the Company may close down operations and
operate as a shell company if the Company cannot raise the cash to continue operations. These matters, among others, raise substantial
doubt about the Company’s ability to continue as a going concern.



Since
inception, the operations of the Company have been funded through the sale of common shares, preferred shares, warrants and convertible
debt. Management cannot be certain that additional funding will be available on acceptable terms, or at all. To the extent that
the Company raises additional funds by issuing equity securities, the Company’s stockholders may experience significant
dilution. Any debt financing, if available, may involve restrictive covenants that could impact the Company’s ability to
conduct business. If the Company is not able to raise additional capital when required or on acceptable terms, the Company may
have to (i) significantly delay, scale back or discontinue the development and/or commercialization of one or more product candidates;
(ii) seek collaborators for product candidates at an earlier stage than otherwise would be desirable and on terms that are less
favorable than might otherwise be available; or (iii) relinquish or otherwise dispose of rights to technologies, product candidates
or products that the Company would otherwise seek to develop or commercialize.



F-7







The
financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.



NOTE
3 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES



Use
of Estimates



The
preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those
estimates and such differences may be material to the financial statements. The more significant estimates and assumptions by
management include among others; the valuation allowance of deferred tax assets resulting from net operating losses and the valuation
of options on the Company’s common stock.



Cash
and Cash Equivalents



Cash
consists of amounts held in financial institutions and consists of immediately available fund balances. The funds are maintained
at stable financial institutions, generally at amounts in excess of federally insured limits. Cash equivalents include money market
funds and held-to-maturity securities with a maturity date of 90 days or less. As of December 31, 2019, cash and cash equivalents
consisted of bank deposits, cash and investments in money market funds.



Investment
in Marketable Securities





Investment in marketable securities is held
in a custodial account at a financial institution and managed by the Company’s capital advisors based on the Company’s
investment guidelines. All of the Company’s investments in marketable securities are classified as available-for-sale debt
securities and are carried at fair value. Interest on these securities, as well as the amortization of discounts and premiums,
is included in interest income in the Statements of Operations and comprehensive loss. The unrealized gains and losses on these
securities are excluded from earnings and reported in other comprehensive loss until realized, except when it considers declines
in value to be other than temporary. Other than temporary impairment losses related to credit losses are considered to be realized
losses. When available-for-sale debt securities are sold, the cost of the securities is specifically identified and is used to
determine the realized gain or loss. Securities classified as current assets have maturity dates of less than or equal to one year
from the balance sheet date.



Property
and Equipment



Property
and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method (see Note
4). Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts
and any resulting gain or loss is credited or charged to income. Maintenance and repairs are charged to expense as incurred while
expenditures for refurbishments and improvements that significantly add to the productive capacity or extend the useful life of
an asset are capitalized.



Impairment
of Long-Lived Assets



The
Company periodically assesses the impairment of long-lived assets in accordance with Accounting Standards Codification (“ASC”)
Topic 360, Property Plant and Equipment. When indicators of impairment are present, the Company evaluates the carrying
value of these assets in relation to the operating performance of the business and future undiscounted cash flows expected to
result from the use of these assets. No such impairments have been recognized during the years ended December 31, 2019 or 2018.



F-8







Clinical
Trial and Pre-Clinical Study Accruals



The
Company makes estimates of accrued expenses as of each balance sheet date in its financial statements based on the facts and circumstances
known to it at that time. Accrued expenses for pre-clinical studies and clinical trials are based on estimates of costs incurred
and fees that may be associated with services provided by contract research organizations, clinical trial investigational sites,
and other related vendors. Payments under certain contracts with such parties depend on factors such as successful enrollment
of patients, site initiation and the completion of milestones. In accruing service fees, management estimates the time period
over which services will be performed and the level of effort to be expended in each period. If possible, the Company obtains
information regarding unbilled services directly from these service providers. However, the Company may be required to estimate
these services based on other information available to it. If the Company underestimates or overestimates the activity or fees
associated with a study or service at a given point in time, adjustments to research and development expenses may be necessary
in future periods. Historically, estimated accrued liabilities have approximated actual expense incurred. Subsequent changes in
estimates may result in a material change in the Company’s accruals.



Research
and Development



The
Company expenses the cost of research and development as incurred. Research and development expenses comprise costs incurred in
performing research and development activities, including clinical trial costs, manufacturing costs for both clinical and pre-clinical
materials as well as other contracted services, license fees, and other external costs. Nonrefundable advance payments for goods
and services that will be used in future research and development activities are expensed when the activity is performed or when
the goods have been received, rather than when payment is made, in accordance with ASC Topic 730, Research and Development.



Patent
Costs



The
Company has no historical data to support a probable future economic benefit for the arising patent applications, filing and prosecution
costs. Therefore, patent costs are expensed as incurred. Should the Company experience a legal cost to defend a patent in the
future, that cost would be capitalized only when it is part of the cost of retaining and obtaining the future economic benefit
of the patent. Costs related to an unsuccessful outcome would be expensed.



Stock-based
Compensation



Stock-based
compensation cost for stock awards issued to employees, members of the Company’s board of directors and non-employees, is
measured at the grant date based on the fair value of the award and is recognized as expense over the required service period,
which is generally equal to the vesting period. Stock-based compensation is recognized only for those awards that are ultimately
expected to vest. Common stock, stock options or warrants issued to non-employees, including consultants and members of the Company’s
Scientific Advisory Board as consideration for goods or services received by the Company, are accounted for based on the fair
value of the equity instruments issued unless the fair value consideration received can be more reliably measured. The fair value
of stock options is determined using the Black-Scholes option-pricing model. The fair value of any options issued to non-employees
is recorded as expense over the vesting period. See Note 8 for further information.



Fair
Value Measurements



The
fair value of the Company’s financial instruments reflects the amounts that it estimates it would receive in connection
with the sale of an asset or pay in connection with the transfer of a liability in an orderly transaction between market participants
at the measurement date (exit price). The Company discloses and recognizes the fair value of its assets and liabilities using
a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority
to valuations based upon unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements)
and the lowest priority to valuations based upon unobservable inputs that are significant to the valuation (Level 3 measurements).
The guidance establishes three levels of the fair value hierarchy as follows:



Level
1 - Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability
to access at the measurement date;



F-9







Level
2 - Inputs other than quoted prices that are observable for the assets or liability either directly or indirectly, including inputs
in markets that are not considered to be active;



Level
3 - Inputs that are unobservable.



Assets
and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant
to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement
in its entirety requires management to make judgments and consider factors specific to the asset or liability.



The
Company recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period. There were no transfers
within the hierarchy during the year ended December 31, 2019.



A
summary of the assets and liabilities carried at fair value in accordance with the hierarchy defined above is as follows:







|                      |  | Fair
    Value Measurements Using |          
|--------------------- |  | --------------------------------- | ---------

The Company
uses a market approach for determining the fair value of all its Level 1 money market funds and marketable securities. To value
its money market funds, the Company values the funds at $1 stable net asset value, which is the market pricing convention for
identical assets that the Company has the ability to access.





The
investments were classified as available-for-sale debt securities. At December 31, 2019, the balance in the Company’s
accumulated other comprehensive loss was comprised primarily of activity related to the Company’s available-for-sale
debt securities and some activity related to held-to-maturity debt securities. Realized gains and losses are included in
earnings The Company had no available-for-sale or held-to-maturity debt securities as of December 31,
2019.



Convertible
Preferred Stock



The
Company follows authoritative accounting guidance to distinguish liabilities from equity when assessing the classification and
measurement of preferred stock. Preferred shares subject to mandatory redemptions are considered liabilities and measured at fair
value. Conditionally redeemable preferred shares are considered temporary equity. All other preferred shares are considered as
stockholders’ equity.



F-10







Accounting
for Income Taxes



Deferred
tax assets and liabilities are recognized for the expected future consequences of events that have been reflected in the financial
statements. Deferred tax assets and liabilities are determined based on the differences between the book and tax basis of assets
and liabilities and operating loss carryforwards, using tax rates expected to be in effect for the years in which the differences
are expected to reverse. Such differences arise primarily from stock-based compensation and net operating loss carryforwards.
The Company records a valuation allowance to reduce deferred income tax assets when it is more likely than not that some portion
or all of the deferred tax asset will not be realized. Prior to September 15, 2008, the Company was a limited liability company
and the Company’s tax losses and credits generally flowed directly to the members.



Net
Loss Per Share



The
Company determines basic net loss per share and diluted net loss per share in accordance with the provisions of ASC 260, “Earnings
per Share.” Basic net loss per share was calculated by dividing net loss by the weighted-average common shares outstanding
during the period. Diluted net loss per share was calculated by dividing net loss by the weighted-average common shares outstanding
during the period using the treasury stock method or the two-class method, whichever is more dilutive. The potentially dilutive
stock options issued under the 2015 Stock Plan (described in Note 8), Series A, Series B and Series C Convertible Preferred Stock
(described in Note 6) and warrants on the Company’s common stock (described in Notes 6 and 7) were not considered in the
computation of diluted net loss per share because they would be anti-dilutive.



Comprehensive
Income (Loss)



Comprehensive
income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner
sources. The Company is required to record all components of comprehensive loss in the financial statements in the period in which
they are recognized. Net income (loss) and other comprehensive loss, including foreign currency translation adjustments and unrealized
gains and losses on investments are reported, net of their related tax effect, to arrive at a comprehensive loss. For the years
ended December 31, 2019 and 2018, comprehensive loss comprised of unrealized losses on investments in available-for-sale debt
securities and held-to-maturity debt securities.



Recent
Accounting Pronouncements



In
June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”)
No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,
an amendment that modifies the measurement recognition of credit losses for most financial assets and certain other instruments.
The amendment updates the guidance for measuring and recording credit losses on financial assets measured at amortized cost by
replacing the “incurred loss” model with an “expected loss” model. Accordingly, these financial assets
will be presented at the net amount expected to be collected. The amendment also requires that credit losses related to available-for-sale
debt securities be recorded as an allowance through net income rather than reducing the carrying amount under the current, other-than-temporary-impairment
model. The FASB also issued subsequent amendments to the initial guidance: ASU 2018-19, ASU 2019-04, and ASU 2019-05 (collectively,
“Topic 326”). Topic 326 requires measurement and recognition of expected credit losses for financial assets held.
The effective date and transition methodology for the amendments in Topic 326 are the same as in ASU 2016-13. The guidance
is effective for public business entities that are SEC filers. The amendments in ASU No. 2016-13 are effective for fiscal years
beginning after December 15, 2019, including interim periods within those fiscal years. For all other public business entities,
the amendments in this ASU are effective for fiscal years beginning after December 15, 2020, including interim periods within
those fiscal years. The Company does not expect the adoption of this guidance will have a material impact on its financial statements.



In
August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework — Changes
to the Disclosure Requirements for Fair Value Measurement”, an amendment to the accounting guidance on fair value measurements.
The guidance modifies the disclosure requirements on fair value measurements, including the removal of disclosures of the amount
of and reasons for transfers between Level 1 of the fair value hierarchy, the policy for timing of transfers between levels, and
the valuation processes for Level 3 fair value measurements. The guidance also adds certain disclosure requirements related to
Level 3 fair value measurements. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning
after December 15, 2019. The Company does not expect the adoption of this guidance will have a material impact on its financial
statements.



F-11







In
December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,”
which is intended to simplify various aspects related to accounting for income taxes. The ASU 2019-12 removes certain exceptions
to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The
ASU 2019-12 is effective for the Company beginning after December 15, 2021. The Company is evaluating the impact of the adoption
of ASU 2019-12 on its financial statements, but does not expect such adoption to have a material impact.



Other
accounting standard updates effective after December 31, 2019 are not expected to have a material impact on the Company’s
financial statements.



Recently
Adopted Accounting Pronouncements





In February
2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under this guidance, an entity is required to recognize right-of-use
(“ROU”) assets and corresponding lease liabilities on its balance sheets and disclose key information about leasing
arrangements. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842) Targeted Improvements, which provides for
an alternative transition method by allowing companies to continue to use the legacy guidance in Topic 840, Leases, including
its disclosure requirements, in the comparative periods presented in the year of adoption of the new leases standard and recognize
a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest
period presented.





The Company
elected the available package of practical expedients,
but not the hindsight practical expedient, and adopted this guidance as of January 1, 2019.



The standard had a material impact on the
Company’s balance sheets, but did not have an impact on its statements of operations and comprehensive loss. The most significant
impact was the recognition of a ROU asset and lease liability for the Company’s sole operating lease—the Company had
no finance leases. Adoption of the standard did not require the Company to restate previously reported results as it elected to
apply a modified retrospective approach at the beginning of the period of adoption rather than at the beginning of the earliest
comparative period presented.



In
June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which expands the
scope of Topic 718 Compensation—Stock Compensation, to include share-based payments issued to nonemployees for goods
or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned.
ASU No. 2018-07 supersedes Subtopic 505-50 Equity—Equity-Based Payments to Non-Employees. The amendments implemented
by ASU No. 2018-07 are effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal
year. The Company adopted ASU 2018-07 on January 1, 2019 and it did not have a material effect on its results of operations, financial
position or cash flows.

NOTE
5 — COMMITMENTS AND CONTINGENCIES



Master
Services Agreement





In May 2018,
Ritter entered into an Amended and Restated Master Services Agreement (“Service Agreement”) with a clinical research
organization (“CRO”), pursuant to which the CRO agreed to perform certain services related to the management and execution
of certain clinical trials involving RP-G28. The Services Agreement supersedes the Master Service Agreement, dated August 30,
2016, that Ritter entered into with the CRO. The precise services to be performed by the CRO under the Services Agreement will
be mutually agreed upon by the parties in writing and set forth in one or more task orders. Ritter is not obligated to purchase
any minimum or specific volume or dollar amount of services under the Services Agreement.



The
term of the Services Agreement is four years from the effective date of the Service Agreement unless earlier terminated. Ritter
may terminate the Services Agreement or any task without cause immediately upon giving the CRO notice of such termination. The
CRO may, with advance notice to Ritter, terminate a task order if Ritter has materially defaulted on its obligations under the
Services Agreement or any task order and has not cured such material default, as described in the Services Agreement.





Clinical
Supply and Cooperation Agreement with Ricerche Sperimentali Montale SpA (“RSM”)





Under the
terms of the Supply Agreement with RSM on July 22, 2015, Ritter is required to pay RSM $400,000 within 10 days following FDA approval
of an NDA for the first product owned or controlled by Ritter using Improved GOS as its active pharmaceutical ingredient.





Offer
Letter Amendments



On
October 15, 2019, Ritter entered into amendments to the respective employment offer letters of Andrew J. Ritter, its Chief Executive
Officer, John W. Beck, its Chief Financial Officer, and Ira E. Ritter, its Chief Strategic Officer (the “Offer Letter Amendments”).
Pursuant to the terms of the Offer Letter Amendments, each of Ritter’s executive officers agreed to defer a portion of his
annual base salary (the “Deferred Amounts”), as set forth below, until such time as the board of directors, in its
sole discretion, decides to pay the Deferred Amounts (or any portion of the Deferred Amounts) to the executive officers, if ever.

Lease
Agreement



On
July 9, 2015, the Company entered into a lease with a California limited partnership, pursuant to which the Company leased
approximately 2,780 square feet of office space in Los Angeles, California for its headquarters. The lease provides for a
term of sixty-one (61) months, commencing on October 1, 2015. The Company paid no rent for the first month of the term and
paid base rent of $9,174 per month for months 2 through 13 of the term, with increasing base rent for each twelve-month
period thereafter under the term of the lease to a maximum of $10,325 per month for months 50 through 61. The base rent
payments do not include the Company’s proportionate share of any operating expenses, including real estate taxes. The
Company has the option to extend the term of the lease for one five-year term, provided that the rent would be subject to
market adjustment at the beginning of the renewal term. Rent expense, recognized on a straight-line basis, was approximately
$117,000 and $118,000 for the years ended December 31, 2019 and 2018, respectively, and is recorded in general and
administrative expenses in the accompanying statements of operations and comprehensive loss.

Legal



From
time to time, we are party to legal claims and proceedings that arise in the ordinary course of business, which may relate to
our operations or assets. These may include disputes and lawsuits related to intellectual property, licensing, contract law and
employee relations matters. Periodically, the Company reviews the status of significant matters, if any exist, and assesses its
potential financial exposure. If the potential loss from any claim or legal claim is considered probable and the amount can be
estimated, the Company accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes
are difficult to predict. Because of such uncertainties, accruals are based on the best information available at the time. As
additional information becomes available, the Company reassesses the potential liability related to pending claims and litigation.
We do not believe that any individual legal claim or proceeding that is currently pending is material to the Company or that these
claims and proceedings in the aggregate are material to the Company.



NOTE
6— STOCKHOLDERS’ EQUITY



Authorized
Shares





In September
2017, the Company amended its Amended and Restated Certificate of Incorporation to authorize the issuance of up to 225,000,000
shares of common stock, $0.001 par value per share, and 15,000,000 of which are designated as preferred stock, consisting of
(i) 9,500 shares that have been designated Series A convertible preferred stock, (ii) 6,000 shares that have been designated as
Series B convertible preferred stock, and (iii) 1,880 shares that have been designated as Series C convertible preferred stock.
Pursuant to the terms of the Certificate of Incorporation, the board of directors has the authority to issue preferred stock in
one or more classes or series and to fix the designations, powers, preferences and rights, and the qualifications, limitations
or restrictions thereof, including dividend rights, conversion right, voting rights, terms of redemption, liquidation preferences
and the number of shares constituting any class or series, without further vote or action by the stockholders.



All
common share amounts and per share amounts were retroactively restated to reflect a 1-for-10 reverse stock split that was effective
March 23, 2018.



As
of December 31, 2019, the Company had 19,108,331 shares of common stock, 0 shares of Series A convertible preferred stock, 1,850
shares of Series B convertible preferred stock and 240 shares of Series C convertible preferred stock issued and outstanding.
Each share of the Company’s common stock is entitled to one vote, and all shares rank equally as to voting and other matters.
Each share of Series A preferred stock is convertible by the holder at $4.00 per share; subject to adjustment for stock splits,
stock dividends, subsequent rights offerings, pro rata distributions, and fundamental transactions. Each share of Series B preferred
stock is convertible by the holder at $1.30 per share; subject to customary adjustment in the event of future stock dividends
and stock splits. Each share of Series C preferred stock is convertible by the holder at $1.64 per share; subject to customary
adjustment in the event of future stock dividends and stock splits. Holders are entitled to receive, and the Company shall pay,
dividends on outstanding shares of Series A preferred stock, on an as-if-converted-to-common-stock basis, equal to and in the
same form as dividends actually paid on outstanding common shares when, as and if such dividends are paid on outstanding common
shares. Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, the holders of Series
A, Series B and Series C preferred stock shall be entitled to receive out of the assets, whether capital or surplus, of the Company
the same amount that a holder of common stock would receive if the Series A, Series B and Series C preferred stock were fully
converted to common stock, which amounts shall be paid pari passu with all common stockholders. Holders of Series A, Series B
and Series C preferred stock have no voting rights. However, as long as any shares of Series A, Series B and Series C preferred
stock are outstanding, the Company shall not, without the affirmative vote of the holders of a majority of the then outstanding
shares of Series A, Series B and Series C preferred stock, (a) alter or change adversely the powers, preferences or rights given
to the Series A, Series B and Series C preferred stock or alter or amend the applicable Certificate of Designation, (b) amend
the Company’s certificate of incorporation or other charter documents in any manner that adversely affects any rights of
the holders of Series A, Series B and Series C preferred stock, (c) increase the number of authorized shares of Series A, Series
B and Series C preferred stock, or (d) enter into any agreement with respect to any of the foregoing.



Aspire
Capital Common Stock Purchase Agreement



On
May 4, 2017, the Company entered into a common stock purchase agreement with Aspire Capital Fund, LLC (“Aspire Capital”),
which the Company and Aspire amended and restated on March 29, 2019 and on July 23, 2019 (as amended and restated, the
“Aspire Purchase Agreement”). The Aspire Purchase Agreement was amended and restated to adjust certain provisions
to improve the Company’s access to funding under the agreement. The Company was not required to pay a commitment fee to
Aspire Capital to affect the amendment to the Aspire Purchase Agreement. The Aspire Purchase Agreement provides access to the
Company of up to an aggregate of $6.5 million in proceeds through the sale of shares of its common stock through March 31, 2021.



F-14









Under the Aspire Purchase Agreement, as
amended, on any trading day the Company selected, it had the right, in its sole discretion, to present Aspire Capital with a purchase
notice (each, a “Purchase Notice”), directing Aspire Capital (as principal) to purchase up to 100,000 shares of its
common stock per trading day (which could be increased by as much as an additional 2,000,000 shares per trading day by mutual
agreement), up to an aggregate of $6,500,000 of its common stock, at a per share price (the “Purchase Price”) equal
to the lesser of: (i) the lowest sale price of the Company’s common stock on the sale date, or (ii) the arithmetic average
of the three lowest closing sale prices for the Company’s common stock during the ten (10) consecutive trading days ending
on the trading day immediately preceding the sale date. The aggregate purchase price payable by Aspire Capital on any one purchase
date could not exceed $500,000, unless otherwise mutually agreed. In addition, on any date on which the Company submitted a Purchase
Notice to Aspire Capital in an amount of at least 100,000 shares and its stock price was not less than $0.25 per share, the Company
could also, in its sole discretion, present Aspire Capital with a volume-weighted average price purchase notice (each, a “VWAP
Purchase Notice”) directing Aspire Capital to purchase an amount of its common stock equal to up to 30% of the aggregate
shares of the Company’s common stock traded on its principal market on the next trading day (the “VWAP Purchase Date”),
as determined by the Company. Under the terms of the Aspire Purchase Agreement, the number of shares that could be sold pursuant
to Aspire Capital was limited to 1,807,562 (the “Exchange Cap”), which represented 19.99% of the Company’s outstanding
shares of common stock as of March 29, 2019, the date the agreement was first amended and restated, unless stockholder approval
or an exception pursuant to the rules of the Nasdaq Capital Market was obtained to issue more than 19.99%. This limitation would
not apply if, at any time the Exchange Cap was reached and at all times thereafter, the average price paid for all shares issued
under the Aspire Purchase Agreement was equal to or greater than $0.86 (the “Minimum Price”), which was the closing
price of the Company’s common stock immediately preceding the signing of the agreement. As of December 31, 2019, the Company
has not sold any shares of common stock under this agreement. Subsequent to December 31, 2019 the Company sold approximately 1.8
million shares of common stock under this agreement resulting in proceeds of approximately $0.5 million.



November
2018 Private Placement Financing



On
November 5, 2018, the Company closed a PIPE financing with certain institutional investors, a key vendor and a member of its board
of directors. Net proceeds from the PIPE financing were approximately $5.5 million, after deducting placement agent fees and other
offering expenses. The securities sold by the Company consisted of 6,000 shares of a newly designated class of Series B convertible
preferred stock of the Company, with a stated value of $1,000 per share and an initial conversion price per share of $1.30 (subject
to customary adjustment for stock dividends and stock splits) and warrants to purchase an aggregate of 2,307,685 shares of the
Company’s common stock. Each investor received a warrant to purchase a number of shares of common stock equal to one half
the number of shares of common stock into which their Series B convertible preferred stock is initially convertible. The warrants
are exercisable immediately for a five-year period and have an exercise price of $1.30 per share (subject to customary adjustment
for stock dividends and stock splits but without the down-round protective provisions of previously issued warrants). The proceeds
received in the PIPE financing were allocated to each instrument on a relative fair value basis. Total proceeds of $6.0 million
were allocated as follows: $1.4 million to warrants issued and $4.6 million to Series B convertible preferred stock. The allocation
resulted in an effective conversion price for the Series B preferred stock that was below the quoted market price of the Company’s
common stock on the closing date. As such, the issuance was considered a beneficial conversion feature equal to the intrinsic
value of the conversion feature on the closing date, resulting in a deemed dividend for the Series B convertible preferred stock
of approximately $0.7 million, recognized on the closing date and recorded as a reduction of income available to common stockholders
in computing basic and diluted loss per share.



Certain
investors in the PIPE financing who at the time of closing of the PIPE financing owned shares of the Company’s Series A
convertible preferred stock, exchanged, on a 1 for 1 share basis, their shares of Series A convertible preferred stock for shares
of a newly designated class of Series C convertible preferred stock of the Company, with a stated value of $1,000 per share and
convertible into shares of the Company’s common stock at an initial conversion price per share of $1.64 (subject to customary
adjustment for stock dividends and stock splits), (“the Exchange”). As the Series A convertible preferred stock contained
a beneficial conversion feature, the Exchange was considered an extinguishment equal to the excess of (a) the fair value of the
consideration transferred to the holders of the Series A convertible preferred stock over (b) the carrying amount of the Series
A convertible preferred stock on the Company’s balance sheet plus (c) the amount previously recognized for the beneficial
conversion feature, or approximately $0.2 million, which was recognized on the closing date and recorded as a reduction of income
available to common stockholders in computing basic and diluted loss per share.

At-the-Market
Offering Agreement





On
November 6, 2019, the Company entered into an at the market sales agreement (“ATM Agreement”) with AGP, pursuant to
which it may offer and sell, from time to time through AGP, shares of its common stock (the “Placement Shares”) having
an aggregate offering price of up to $3,673,159 (which was subsequently increased to $8,030,917), subject to the terms and conditions
of the ATM Agreement. Unless earlier terminated pursuant to the terms of the ATM Agreement, the ATM Agreement will automatically
terminate upon the earlier to occur of (i) issuance and sale of all of the Placement Shares to or through AGP and (ii) August
1, 2022. As of December 31, 2019, the Company sold approximately 8.1 million shares of common stock under the ATM Agreement resulting
net proceeds to of approximately $1.4 million after commissions and expenses of approximately $50,000. Subsequent to December
31, 2019 the Company sold approximately 16.8 million shares of common stock under this agreement resulting in net proceeds of
approximately $4.4 million after commissions and expenses of approximately $0.2 million.



NOTE
7 — WARRANTS

to purchase an aggregate of 8,413,017 shares of the Company’s common stock were outstanding at December 31, 2019.
These warrants are all vested and exercisable, have exercise prices ranging from $0.15 to $93.00 per share, with a weighted
average exercise price of $0.95, and expire at various dates through November 2023.

The
exercise price for an option issued under the Plans is determined by the Board of Directors, but will be (i) in the case of an
incentive stock option (A) granted to an employee who, at the time of grant of such option, is a 10% stockholder, no less than
110% of the fair market value per share on the date of grant; or (B) granted to any other employee, no less than 100% of the fair
market value per share on the date of grant; and (ii) in the case of a non-statutory stock option, no less than 100% of the fair
market value per share on the date of grant. The options awarded under the Plans will vest as determined by the Board of Directors
but will not exceed a ten-year period. The weighted average grant date fair value per share of options granted during the year
ended December 31, 2019 was $0.62.

The
Company utilizes the Black-Scholes option pricing model to value awards under its Plans. Key valuation assumptions include:

    dividend yield.The expected dividend is assumed to be zero as the Company has never paid dividends and has no current
    plans to pay any dividends on the Company’s common stock.

    is derived from the average historical volatilities of publicly traded companies within the Company’s industry that
    the Company considers to be comparable to the Company’s business over a period approximately equal to the expected term.

|● | Expected
    term.The expected term represents the period that the stock-based awards are expected to be outstanding. The Company’s
    historical share option exercise experience does not provide a reasonable basis upon which to estimate an expected term because
    of a lack of sufficient data. Therefore, the Company estimates the expected term by using the simplified method provided by
    the SEC. The simplified method calculates the expected term as the average of the time-to-vesting and the contractual life
    of the options.



The
material factors incorporated in the Black-Scholes model in estimating the fair value of the options granted for the periods presented

Compensation



The
Company recognized stock-based compensation expense for services within general and administrative expense in the accompanying
statements of operations of approximately $438,000 and $646,000 for the years ended December 31, 2019 and 2018, respectively.
As of December 31, 2019, there was approximately $254,000 of total unrecognized compensation cost related to unvested stock-based
compensation arrangements. This cost is expected to be recognized over a weighted average period of 1.4 years.



No
stock options were exercised during the year ended December 31, 2019 and 2018.



NOTE
9 — RELATED PARTY TRANSACTIONS



A
director of the Company is a managing director of Javelin Venture Partners GP, LLC, the general partner of Javelin Venture Partners
GP, L.P., which holds a significant investment in the Company’s common stock and warrants. Two directors of the Company
have acted as a managing director of Stonehenge Partners, LLC, which holds an investment in the Company’s common
stock.



Other

have a direct or indirect material interest.



NOTE
10 — INCOME TAXES



As
of December 31, 2019, the Company has net operating loss carryforwards of approximately $63.5 million available to reduce
future taxable income, if any, for Federal and state income tax purposes. The U.S. federal and state net operating loss carryforwards
will begin to expire in 2028.



As
of December 31, 2019, the Company has Federal and state research and development credit carryforwards of approximately $3.2 million
and $3.1 million, respectively, available to reduce future taxable income, if any, for Federal and state income tax purposes.
The Federal credit carryforwards begin to expire in 2029. California credits have no expiration date.



Under
the Internal Revenue Code (“IRC”) Sections 382 and 383, annual use of the Company’s net operating loss and research
tax credit carryforwards to offset taxable income may be limited based on cumulative changes in ownership. The Company has not
completed an analysis to determine whether any such limitations have been triggered as of December 31, 2019. The Company has no
income tax affect due to the recognition of a full valuation allowance on the expected tax benefits of future loss carry forwards
based on uncertainty surrounding realization of such assets.



A
reconciliation of the statutory income tax rates and the Company’s effective tax rate is as follows:

The
Company did not record any accruals for income tax accounting uncertainties for the years ended December 31, 2019 and 2018.



Authoritative
guidance requires companies to accrue interest and related penalties, if applicable, on all tax positions for which reserves have
been established consistent with jurisdictional tax laws. The Company’s policy is to recognize interest and penalties that
would be assessed in relation to the settlement value of unrecognized tax benefits as a component of income tax expense. The Company
did not accrue either interest or penalties from inception through December 31, 2019.



The
Company does not have any unrecognized tax benefits that will significantly decrease or increase within 12 months of December
31, 2019.



The
Company’s major tax jurisdictions are the United States and California. All of the Company’s tax years will remain
open three and four years for examination by the Federal and state tax authorities, respectively, from the date of utilization
of the net operating loss. The Company does not have any tax audits pending.



NOTE
                                         11 — SUBSEQUENT EVENTS







On January 15, 2020,
Ritter entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Qualigen Inc. (“Qualigen”),
pursuant to which the Merger Sub will merge with and into Qualigen, with Qualigen surviving as a wholly owned subsidiary of Ritter.
Upon closing, on a pro forma basis and based upon the number of shares of Ritter common stock expected to be issued in the merger,
the pre-merger Ritter securityholders are expected to own approximately 7.5% of the combined company, on a fully diluted basis,
and the pre-merger Qualigen securityholders are expected to own approximately 92.5% of the combined company, on a fully diluted
basis. To consummate the merger, Ritter and Qualigen stockholders must adopt and approve the Merger Agreement and a series of
Merger-related proposals. In addition to obtaining such stockholder approvals and appropriate regulatory approvals, each of the
other closing conditions set forth in the Merger Agreement must be satisfied or waived.



Risks Related to COVID-19 Pandemic



The recent outbreak of COVID-19 originated
in Wuhan, China, in December 2019 and has since spread to multiple countries, including the United States and several European
countries. On March 11, 2020, the World Health Organization declared the outbreak a pandemic. The COVID-19 pandemic is affecting
the United States and global economies and may affect the Company’s operations and those of third parties on which the Company
relies. While the potential economic impact brought by, and the duration of, the COVID-19 pandemic is difficult to assess or predict,
the impact of the COVID-19 pandemic on the global financial markets may reduce the Company’s ability to access capital,
which could negatively impact the Company’s short-term and long-term liquidity and the Company’s and Qualigen’s
ability to complete the Plan of Merger on a timely basis or at all. The ultimate impact of the COVID-19 pandemic is highly uncertain
and subject to change. The Company does not yet know the full extent of potential delays or impacts on its business, financing
or other activities or on healthcare systems or the global economy as a whole. However, these effects could have a material impact
on the Company’s liquidity, capital resources, operations and business and those of the third parties on which we rely.
