AMENDED
AND RESTATED COMMON STOCK PURCHASE AGREEMENT


 


This
AMENDED AND RESTATED COMMON STOCK PURCHASE AGREEMENT (the “Agreement”) is entered into as of July 23,
2019, by and between RITTER PHARMACEUTICALS, INC., a Delaware corporation (the “Company”), and ASPIRE
CAPITAL FUND, LLC, an Illinois limited liability company (the “Buyer”). This Agreement hereby amends and
restates the Common Stock Purchase Agreement entered into between the parties as of May 4, 2017, as amended and restated as of
March 29, 2019. Capitalized terms used herein and not otherwise defined herein are defined in Section 10 hereof.


 


WHEREAS:


 


Subject
to the terms and conditions set forth in this Agreement, the Company wishes to sell to the Buyer, and the Buyer wishes to buy
from the Company, up to Six Million Five Hundred Thousand Dollars ($6,500,000) of the Company’s common stock, par value
$0.001 per share (the “Common Stock”). The shares of Common Stock to be purchased hereunder are referred to
herein as the “Purchase Shares.”


 


NOW
THEREFORE, the Company and the Buyer hereby agree as follows:


 


1.
PURCHASE OF COMMON STOCK.


 


Subject
to the terms and conditions set forth in this Agreement, the Company has the right to sell to the Buyer, and the Buyer has the
obligation to purchase from the Company, Purchase Shares as follows:


 


(a)
Commencement of Purchases of Common Stock. Any time after Commencement (as defined below), the purchase and sale of Purchase
Shares hereunder may occur from time to time upon written notices by the Company to the Buyer on the terms and conditions as set
forth herein following the satisfaction of the conditions (the “Commencement”) as set forth in Sections 6 and
7 below (the date of satisfaction of such conditions, the “Commencement Date”).


 


(b) The
Company’s Right to Require Regular Purchases. Subject to the terms and conditions of this Agreement, on any
given Business Day after the Commencement Date, the Company shall have the right but not the obligation to direct the Buyer
by its delivery to the Buyer of a Purchase Notice from time to time, and the Buyer thereupon shall have the obligation, to
buy the number of Purchase Shares specified in such notice, up to 100,000 Purchase Shares, on such Business Day (as long as
such notice is delivered on or before 5:00 p.m. Eastern time on such Business Day) (each such purchase, a “Regular
Purchase”) at the Purchase Price on the Purchase Date; however, in no event shall the Purchase Amount of a Regular
Purchase exceed Five Hundred Thousand Dollars ($500,000) per Business Day. The Company may deliver additional Purchase
Notices to the Buyer from time to time so long as the most recent purchase has been completed. The share amounts in this
Section 1(b) shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split,
reverse stock split or other similar transaction.


 




    	 	 	 



    	 



    

 


(c)
VWAP Purchases. Subject to the terms and conditions of this Agreement, in addition to purchases of Purchase Shares as described
in Section 1(b) above, with one Business Day’s prior written notice (as long as such notice is delivered on or before 5:00
p.m. Eastern time on the Business Day immediately preceding the VWAP Purchase Date), the Company shall also have the right but
not the obligation to direct the Buyer by the Company’s delivery to the Buyer of a VWAP Purchase Notice from time to time,
and the Buyer thereupon shall have the obligation, to buy the VWAP Purchase Share Percentage of the trading volume of the Common
Stock on the VWAP Purchase Date up to the VWAP Purchase Share Volume Maximum on the VWAP Purchase Date (each such purchase, a
“VWAP Purchase”) at the VWAP Purchase Price. The Company may deliver a VWAP Purchase Notice to the Buyer on
or before 5:00 p.m. Eastern time on a date on which the Company also submitted a Purchase Notice for a Regular Purchase of at
least 100,000 Purchase Shares to the Buyer. The share amount in the prior sentence shall be appropriately adjusted for any reorganization,
recapitalization, non-cash dividend, stock split, reverse stock split, or other similar transaction. A VWAP Purchase shall automatically
be deemed completed at such time on the VWAP Purchase Date that the Sale Price falls below the VWAP Minimum Price Threshold; in
such circumstance, the VWAP Purchase Amount shall be calculated using (i) the VWAP Purchase Share Percentage of the aggregate
shares traded on the Principal Market for such portion of the VWAP Purchase Date prior to the time that the Sale Price fell below
the VWAP Minimum Price Threshold and (ii) a VWAP Purchase Price calculated using the volume weighted average price of Common Stock
sold during such portion of the VWAP Purchase Date prior to the time that the Sale Price fell below the VWAP Minimum Price Threshold.
Each VWAP Purchase Notice must be accompanied by instructions to the Company’s Transfer Agent to immediately issue to the
Buyer an amount of Common Stock equal to the VWAP Purchase Share Estimate, a good faith estimate by the Company of the number
of Purchase Shares that the Buyer shall have the obligation to buy pursuant to the VWAP Purchase Notice. In no event shall the
Buyer, pursuant to any VWAP Purchase, purchase a number of Purchase Shares that exceeds the VWAP Purchase Share Estimate issued
on the VWAP Purchase Date in connection with such VWAP Purchase Notice; however, the Buyer will immediately return to the Company
any amount of Common Stock issued pursuant to the VWAP Purchase Share Estimate that exceeds the number of Purchase Shares the
Buyer actually purchases in connection with such VWAP Purchase. Upon completion of each VWAP Purchase Date, the Buyer shall submit
to the Company a confirmation of the VWAP Purchase in form and substance reasonably acceptable to the Company. The Company may
deliver additional VWAP Purchase Notices to the Buyer from time to time so long as the most recent purchase has been completed.


 


(d)
Payment for Purchase Shares. For each Regular Purchase, the Buyer shall pay to the Company an amount equal to the Purchase
Amount as full payment for such Purchase Shares via wire transfer of immediately available funds on the same Business Day that
the Buyer receives such Purchase Shares. For each VWAP Purchase, the Buyer shall pay to the Company an amount equal to the VWAP
Purchase Amount as full payment for such Purchase Shares via wire transfer of immediately available funds on the second Business
Day following the VWAP Purchase Date. All payments made under this Agreement shall be made in lawful money of the United States
of America via wire transfer of immediately available funds to such account as the Company may from time to time designate by
written notice in accordance with the provisions of this Agreement. Whenever any amount expressed to be due by the terms of this
Agreement is due on any day that is not a Business Day, the same shall instead be due on the next succeeding day that is a Business
Day.


 


(e)
Purchase Price Floor. The Company and the Buyer shall not effect any sales under this Agreement on any Purchase Date where
the Closing Sale Price is less than the Floor Price. “Floor Price” means $0.25 per share of Common Stock, which
shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split
or other similar transaction.


 


(f)
Records of Purchases. The Buyer and the Company shall each maintain records showing the remaining Available Amount at any
given time and the dates and Purchase Amounts for each purchase, or shall use such other method reasonably satisfactory to the
Buyer and the Company to reconcile the remaining Available Amount.


 




    	 	- 2-	 



    	 



    

 


(g)
Taxes. The Company shall pay any and all transfer, stamp or similar taxes that may be payable with respect to the issuance
and delivery of any shares of Common Stock to the Buyer made under this Agreement.


 


(h)
Compliance with Principal Market Rules. Notwithstanding anything in this Agreement to the contrary, and in addition to
the limitations set forth in Section 1(e), the total number of shares of Common Stock that may be issued under this Agreement,
including the Commitment Shares (as defined in Section 4(e) hereof), shall be limited to 1,807,562 shares of Common Stock (the
“Exchange Cap”), which equals 19.99% of the Company’s outstanding shares of Common Stock as of the date
of the Common Stock Purchase Agreement dated May 4, 2017, as amended and restated as of March 29, 2019, unless stockholder approval
is obtained to issue more than such 19.99%. The Exchange Cap shall be appropriately adjusted for any reorganization, recapitalization,
non-cash dividend, stock split, reverse stock split or other similar transaction. The foregoing limitation shall not apply if
stockholder approval has not been obtained and at any time the Exchange Cap is reached and at all times thereafter the average
price paid for all shares of Common Stock issued under this Agreement is equal to or greater than $0.86 (the “Minimum
Price”), a price equal to the lower of (1) the Closing Sale Price immediately preceding the execution of the Common
Stock Purchase Agreement dated May 4, 2017, as amended and restated as of March 29, 2019 or (2) the arithmetic average of the
five (5) Closing Sale Prices for the Common Stock immediately preceding the execution of the Common Stock Purchase Agreement dated
May 4, 2017, as amended and restated as of March 29, 2019 (in such circumstance, for purposes of the Principal Market, the transaction
contemplated hereby would not be “below market” and the Exchange Cap would not apply). The Minimum Price shall be
appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other
similar transaction. Notwithstanding the foregoing, the Company shall not be required or permitted to issue, and the Buyer shall
not be required to purchase, any shares of Common Stock under this Agreement if such issuance would violate the rules or regulations
of the Principal Market. The Company may, in its sole discretion, determine whether to obtain stockholder approval to issue more
than 19.99% of its outstanding shares of Common Stock hereunder if such issuance would require stockholder approval under the
rules or regulations of the Principal Market.


 


(i)
Beneficial Ownership Limitation. The Company shall not issue and the Buyer shall not purchase any shares of Common Stock
under this Agreement if such shares proposed to be issued and sold, when aggregated with all other shares of Common Stock then
owned beneficially (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934
Act”) and Rule 13d-3 promulgated thereunder) by the Buyer and its affiliates would result in the beneficial ownership
by the Buyer and its affiliates of shares in excess of the Exchange Cap.

The
Buyer represents and warrants to the Company that as of the date hereof and as of the Commencement Date:

contained in Section 3 below. The Buyer has sought such accounting, legal and tax advice as it has considered necessary to make
an informed investment decision with respect to its acquisition of the Securities.

permitting such Securities to be sold, assigned or transferred without such registration; (ii) any sale of the Securities made
in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable,
any resale of the Securities under circumstances in which the seller (or the person through whom the sale is made) may be deemed

Act or the rules and regulations of the SEC thereunder; and (iii) neither the Company nor any other person is under any obligation
to register the Securities under the 1933 Act or any state securities laws or to comply with the terms and conditions of any exemption
thereunder.

or authorization by the Buyer, its managers or its members.

(j)
No Prior Short Selling. The Buyer represents and warrants to the Company that at no time prior to the date of this Agreement

requirements of the 1934 Act (all of the foregoing filed prior to the date hereof and all exhibits included therein and financial
statements and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC
Documents”). As of their respective dates (except as they have been correctly amended), the SEC Documents complied in
all material respects with the requirements of the 1934 Act and the rules and regulations of the SEC promulgated thereunder applicable
to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC (except as they may have been properly
amended), contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.
As of their respective dates (except as they have been properly amended), the financial statements of the Company included in
the SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules
and regulations of the SEC with respect thereto. Such financial statements have been prepared in accordance with generally accepted
accounting principles, consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes
or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company as
of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments). Except as disclosed in Schedule 3(f) or routine correspondence, such as comment
letters and notices of effectiveness in connection with previously filed registration statements or periodic reports publicly
available on EDGAR, to the Company’s knowledge, the Company or any of its Subsidiaries are not on the date hereof the subject
of any inquiry, investigation or action by the SEC.


 


(g)
Absence of Certain Changes. Except as disclosed in Schedule 3(g), since March 31, 2019, there has been no material adverse
change in the business, properties, operations, financial condition or results of operations of the Company or its Subsidiaries
taken as a whole. For purposes of this Agreement, neither a decrease in cash or cash equivalents or in the market price of the
Common Stock nor losses incurred in the ordinary course of the Company’s business shall be deemed or considered a material
adverse change. The Company has not taken any steps, and does not currently expect to take any steps, to seek protection pursuant
to any Bankruptcy Law nor does the Company or any of its Subsidiaries have any knowledge or reason to believe that its creditors
intend to initiate involuntary bankruptcy or insolvency proceedings. The Company is financially solvent and is generally able
to pay its debts as they become due.

(h)
Absence of Litigation. Except as disclosed in Schedule 3(h), to the Company’s knowledge, there is no action, suit,
proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or
body pending or, to the knowledge of the Company or any of its Subsidiaries, threatened against the Company, the Common Stock
or any of the Company’s Subsidiaries or any of the Company’s or the Company’s Subsidiaries’ officers or
directors in their capacities as such, which could reasonably be expected to have a Material Adverse Effect (each, an “Action”).
A description of each such Action, if any, is set forth in Schedule 3(h).


 


(i)
Acknowledgment Regarding Buyer’s Status. The Company acknowledges and agrees that the Buyer is acting solely in the
capacity of arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and
thereby. The Company further acknowledges that the Buyer is not acting as a financial advisor or fiduciary of the Company (or
in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby and any
advice given by the Buyer or any of its representatives or agents in connection with the Transaction Documents and the transactions
contemplated hereby and thereby is merely incidental to the Buyer’s purchase of the Securities. The Company further represents
to the Buyer that the Company’s decision to enter into the Transaction Documents has been based solely on the independent
evaluation by the Company and its representatives and advisors.


 


(j)
Intellectual Property Rights. To the Company’s knowledge, the Company and its Subsidiaries own or possess adequate
rights or licenses to use all material trademarks, trade names, service marks, service mark registrations, service names, patents,
patent rights, copyrights, inventions, licenses, approvals, governmental authorizations, trade secrets and other intellectual
property rights (collectively, “Intellectual Property”) necessary to conduct their respective businesses as
now conducted, except as set forth in Schedule 3(j) or to the extent that the failure to own, possess, license or otherwise hold
adequate rights to use Intellectual Property would not, individually or in the aggregate, have a Material Adverse Effect. Except
as disclosed in Schedule 3(j), to the Company’s knowledge, none of the Company’s active and registered Intellectual

DISCLOSURE
SCHEDULES


 


In
connection with that certain Amended and Restated Common Stock Purchase Agreement, dated as of July 23, 2019 (the “Agreement”),
by and between Aspire Capital Fund, LLC, an Illinois limited liability company (“Buyer”), and Ritter Pharmaceuticals,
Inc., a Delaware corporation (the “Company”), the Company hereby delivers to Buyer these Disclosure Schedules to the
Company’s representations and warranties given in the Agreement. The section numbers in the Disclosure Schedules correspond
to the section numbers in the Agreement; provided, however, that any information disclosed herein under any section number shall
be deemed to be disclosed and incorporated in any other section of the Agreement where such disclosure is clearly referenced.
Disclosure of any information or document herein is not a statement or admission that it is material. Capitalized terms used but
not defined herein shall have the same meanings given them in the Agreement.


 


Schedule
3(a) – Subsidiaries


 


The
State of Delaware has assessed the Company’s 2019 franchise taxes, which would otherwise be due in 2020 for the 2019 fiscal
year, based on what the Company owed in 2018. Based on this assessment, the State of Delaware has informed the Company that it
currently owes the State of Delaware $80,000 for first quarter 2019 franchise taxes, $40,000 for second quarter 2019 franchise
taxes, and $40,000 for third quarter franchise taxes, plus $2,400 interest. This advance payment of estimated franchise tax is
required for any corporation that had a franchise tax liability of $5,000 or more for the prior year. The Company believes, based
on its current financial metrics, that its 2019 franchise taxes will be significantly less than its 2018 franchise taxes and has
not yet made a payment to the State of Delaware for the first quarter 2019 franchise tax. Until this amount is paid, the State
of Delaware will treat the Company as not being in good standing.


 


Schedule
3(c) - Capitalization


 


The
Company has three equity incentive plans; namely the 2008 Stock Plan (the “2008 Plan”), the 2009 Stock Plan (the “2009
Plan”) and the 2015 Equity Incentive Plan (the “2015 Plan”) and options outstanding thereunder. Each of the
2008 Plan, the 2009 Plan and the 2015 Plan has been filed with Securities and Exchange Commission. The 2008 Plan provides for
the grant of stock options and restricted stock awards. The 2009 Plan provides for the grant of stock options, restricted stock
awards and stock purchase rights. The 2015 Plan provides for the grant of options, restricted stock, stock appreciation rights,
performance based awards, dividend equivalents, deferred stock, stock payments and restricted stock units. Effective upon the
adoption of the 2015 Plan, no further awards may be issued under the 2008 Plan or the 2009 Plan. The number of shares that have
been reserved for future issuance pursuant to these plans is as set forth in Section 3(c) of the Agreement.


 


The
Company has outstanding stock options covering an aggregate of 1,341,135 shares of common stock, of which 187,259 were granted
under the 2008 Plan and 1,153,876 were granted under the 2015 Plan. This number does not include an aggregate of 25,000 option
shares that have been promised to two new employees who joined the Company in April 2019, as these awards have not yet been approved
by the Company’s board of directors.


 


The
Company has outstanding 1,410,000 restricted stock units. Each restricted stock unit represents a contingent right to receive
one share of the Issuer’s common stock provided certain timing and/or performance conditions are satisfied.


 




    	 	 	 



    	 



    

 


The
Company has outstanding warrants covering an aggregate of 8,413,017 shares of common stock, which warrants have a weighted average
exercise price of $1.78 per share.


 


A
total of 3,166,338 shares have been reserved for issuance upon conversion of the Company’s Series A, B and C preferred stock.


 


The
Company is party to an Amended and Restated Investors’ Rights Agreement, dated as of November 17, 2010, as amended to date
(copies of such agreement and amendments have been filed with the Securities and Exchange Commission).


 


The
Company is a party to a Registration Rights Agreement with Buyer, dated May 4, 2017.


 


The
Company is a party to a Registration Rights Agreement with the several purchasers named therein, dated as of October 30, 2018
(a copy of which has been filed with the Securities and Exchange Commission).


 


The
Company is a party to a Warrant Agency Agreement with Corporate Stock Transfer, as Warrant Agent, dated as of September 29, 2017,
pursuant to which it issued 57,500,000 warrants (the “2017 Warrants”) to investors as part of a registered public
offering. Pursuant to Section 4.3 of the Warrant Agency Agreement, if at any time prior to September 29, 2022, the Company issues
any securities at an effective price per share less than the exercise price of the 2017 Warrants then in effect (currently $1.30
per share), then the exercise price of the 2017 Warrants will be reduced to equal the lower price (with limited exceptions, for
which sales to Buyer under the Agreement would not qualify).


 


The
Company is a party to a Securities Purchase Agreement with the purchasers named therein, dated October 30, 2018. The Securities
Purchase Agreement contains a provision (Section 4.12) that prohibits the Company from issuing any shares at an effective price
per share less than $1.64 until the 135th day immediately after the date on which the Company first publicly announces (through
the issuance of a press release or other public announcement or by filing or furnishing a current report on Form 8-K or other
filing, report or statement with the SEC under the Securities Exchange Act of 1934, as amended) topline data from its Phase 3
clinical trial (G28-006) of the Company’s RP-G28 drug candidate for the treatment of lactose intolerance (the “Phase
3 Data Release Date”), $1.64 per share of Common Stock, which shall be appropriately adjusted for any reorganization, recapitalization,
non-cash dividend, stock split, reverse stock split or other similar transaction
