(a)     On or prior to each Filing Date, the Company shall prepare and file with the Commission a Registration Statement
covering the resale of all of the Registrable Securities that are not then registered on an effective Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415. Each Registration Statement filed hereunder shall be
on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on

Annex A; provided, however, that no Holder shall be required to be named as an “underwriter” without such Holder’s express prior written consent. Subject to the terms of this Agreement, the Company shall use its
best efforts to cause a Registration Statement filed under this Agreement (including, without limitation, under Section 3(c)) to be declared effective under the Securities Act as promptly as possible after the filing thereof, but in any event
no later than the applicable Effectiveness Date, and shall use its best efforts to keep such Registration Statement continuously effective under the Securities Act until the date that all Registrable Securities covered by such Registration Statement
(i) have been sold, thereunder or pursuant to Rule 144, or (ii) may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without the
requirement for the Company to be in compliance with the current public information requirement under Rule 144, as determined by the counsel to the Company pursuant to a written opinion letter to such effect, addressed and acceptable to the Transfer
Agent and the affected Holders (the “Effectiveness Period”). The Company shall telephonically request effectiveness of a Registration Statement as of 5:00 p.m. (New York City time) on a Trading Day. The Company shall immediately
notify the Holders via facsimile or by e-mail of the effectiveness of a Registration Statement on the same Trading Day that the Company telephonically confirms effectiveness with the Commission, which shall be
the date requested for effectiveness of such Registration Statement. The Company shall, by 9:30 a.m. (New York City time) by the second Trading Day after the effective date of such Registration Statement, file a final Prospectus with the Commission
as required by Rule 424. Failure to so notify the Holder within one (1) Trading Day of such notification of effectiveness or failure to file a final Prospectus as foresaid shall be deemed an Event under Section 2(d). 

(b)     Notwithstanding the registration obligations set forth in Section 2(a), if the Commission informs the Company
that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly inform each of the Holders thereof and use
its commercially reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission, covering the maximum number of Registrable Securities permitted to be registered by the Commission, on Form S-3 or such other form available to register for resale the Registrable Securities as a secondary offering, subject to the provisions of Section 2(e); with respect to filing on Form S-3 or other appropriate form, and subject to the provisions of Section 2(d) with respect to the payment of liquidated damages; provided, however, that prior to filing such amendment, the Company
shall be obligated to use diligent efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, Compliance and Disclosure Interpretation 612.09.

 (c)     Notwithstanding any other provision of this Agreement and subject to the payment of liquidated damages
pursuant to Section 2(d), if the Commission or any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that
the Company used diligent efforts to advocate with the Commission for the registration of all or a greater portion of Registrable Securities), unless otherwise directed in writing by a Holder as to its Registrable Securities, the number of
Registrable Securities to be registered on such Registration Statement will be reduced as follows: 
 (i)     First,
the Company shall reduce or eliminate any securities to be included other than Registrable Securities; and 

  
 3 

 (ii)     Second, the Company shall reduce Registrable Securities
represented by Shares (applied, in the case that some Shares may be registered, to the Holders on a pro rata basis based on the total number of unregistered Shares held by such Holders). 

In the event of a cutback hereunder, the Company shall give the Holder at least five (5) Trading Days prior written notice along with the
calculations as to such Holder’s allotment. In the event the Company amends the Initial Registration Statement in accordance with the foregoing, the Company will use its best efforts to file with the Commission, as promptly as allowed by
Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or such other form available to register for resale those
Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended. 
 (d)    
If (i) the Initial Registration Statement is not filed on or prior to its Filing Date or (ii) the Company fails to file with the Commission a request for acceleration of a Registration Statement in accordance with Rule 461 promulgated by
the Commission pursuant to the Securities Act, within ten (10) Trading Days of the date that the Company is notified (orally or in writing, whichever is earlier) by the Commission that such Registration Statement will not be
“reviewed” or will not be subject to further review, or (iii) prior to the effective date of a Registration Statement, the Company fails to file a pre-effective amendment and otherwise respond
in writing to comments made by the Commission in respect of such Registration Statement within fifteen (15) calendar days after the receipt of comments by or notice from the Commission that such amendment is required in order for such
Registration Statement to be declared effective, or (iv) a Registration Statement registering for resale all of the Registrable Securities, subject to the cutback limitations set forth in Section 2(c) of this Agreement, is not declared
effective by the Commission by the Effectiveness Date of the Initial Registration Statement, or (v) after the effective date of a Registration Statement, such Registration Statement ceases for any reason to remain continuously effective as to
all Registrable Securities included in such Registration Statement, or the Holders are otherwise not permitted to utilize the Prospectus therein to resell such Registrable Securities, for more than twenty (20) consecutive calendar days which
will not occur more than twice during any 12-month period (any such failure or breach being referred to as an “Event”, and for purposes of clauses (i) and (iv), the date on which such
Event occurs, and for purpose of clause (ii) the date on which such ten (10) Trading Day period is exceeded, and for purpose of clause (iii) the date which such fifteen (15) calendar day period is exceeded, and for purpose of
clause (v) the date on which such twenty (20) calendar day period, as applicable, is exceeded being referred to as “Event Date”), then, in addition to any other rights the Holders may have hereunder or under applicable
law, on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as
partial liquidated damages and not as a penalty, equal to the product of 2.0% multiplied by the aggregate Purchase Price paid by such Holder pursuant to the Purchase Agreement for the relevant Registrable Securities (which with respect to the
Conversion Shares, the Purchase Price paid for the Preferred Shares from which such Conversion Shares were converted). If the Company fails to pay any partial liquidated damages pursuant to this Section in full within twelve days after the date
payable, the Company will pay interest thereon at a rate of 18% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Holder, accruing daily from the date such partial liquidated damages are due until such
amounts, plus all such interest thereon, are paid in full The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro rata basis for any portion of a month prior to the cure of an Event. The Company shall not accrue any
liquidated damages under this Section 2(d) beyond the 366th day from the date of this Agreement, provided, that amounts that have accrued will remain due until paid in full. 

(e)     If Form S-3 is not available for the registration of the resale of
Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable Securities on another appropriate form and (ii) undertake to register the Registrable Securities on Form
S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the Commission. 

(f)     Notwithstanding anything to the contrary contained herein, in no event shall the Company be permitted to name any
Holder or affiliate of a Holder as any Underwriter without the prior written consent of such Holder.

 3.     Registration Procedures. 

In connection with the Company’s registration obligations hereunder, the Company shall: 

(a)     Not less than five (5) Trading Days prior to the filing of each Registration Statement and not less than one

each Holder copies of all such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the review of such Holders, and (ii) cause its officers and directors,

The Company shall not file a Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable Securities shall reasonably object in good faith, provided that, the Company is
notified of such objection in writing no later than five (5) Trading Days after the Holders have been so furnished copies of a Registration Statement or one (1) Trading Day after the Holders have been so furnished copies of any related
Prospectus or amendments or supplements thereto. Each Holder agrees to furnish to the Company a completed questionnaire in the form attached to this Agreement as Annex B (a “Selling Shareholder Questionnaire”) on a date that
is not less than two (2) Trading Days prior to the Filing Date or by the end of the fourth (4th) Trading Day following the date on which such Holder receives draft materials in accordance
with this Section. 
 (b)     (i) Prepare and file with the Commission such amendments, including post-effective
amendments, to a Registration Statement and the Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and prepare
and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities, (ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented or amended, to be filed pursuant to Rule 424, (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect to a
Registration Statement or any amendment thereto and provide as promptly as reasonably possible to the Holders true and complete copies of all correspondence from and to the Commission relating to a Registration Statement (provided that, the Company
shall excise any information contained therein which would constitute material non-public information regarding the Company or any of its Subsidiaries), and (iv) comply in all material respects with the
applicable provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration Statement during the applicable period in accordance (subject to the terms of this Agreement)
with the intended methods of disposition by the Holders thereof set forth in such Registration Statement as so amended or in such Prospectus as so supplemented. 

(c)     If during the Effectiveness Period, the number of Registrable Securities at any time exceeds 100% of the number of
shares of Common Stock then registered in a Registration Statement, then the Company shall file as soon as reasonably practicable, but in any case prior to the applicable Filing Date, an additional Registration Statement covering the resale by the
Holders of not less than the number of such Registrable Securities. 
 (d)     Notify the Holders of Registrable
Securities to be sold (which notice shall, pursuant to clauses (iii) through (vi) hereof, be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably possible (and,
in the case of (i)(A) below, not less than one (1) Trading Day prior to such filing) and (if requested by any such Person) confirm such notice in writing no later than one (1) Trading Day following the day (i)(A) when a Prospectus or any
Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed, (B) when the Commission notifies the Company whether there will be a “review” of such Registration Statement and whenever the
Commission comments in writing on such Registration Statement, and (C) with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (ii) of any request by the Commission or any other federal
or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information, (iii) of the issuance by the Commission or any other federal or state governmental authority of any stop
order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose, (iv) of the receipt by the Company of any notification with respect to the
suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any 

  
 5 

 
jurisdiction, or the initiation or threatening of any Proceeding for such purpose, (v) of the occurrence of any event or passage of time that makes the financial statements included in a
Registration Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires
any revisions to a Registration Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vi) of the occurrence or existence of any pending corporate development with
respect to the Company that the Company believes may be material and that, in the determination of the Company, makes it not in the best interest of the Company to allow continued availability of a Registration Statement or Prospectus;
provided, however, that in no event shall any such notice contain any information which would constitute material, non-public information regarding the Company or any of its Subsidiaries. 

(e)     Use its best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order stopping
or suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

 (f)     Furnish to each Holder, without charge, at least one conformed copy of each such Registration Statement and
each amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference to the extent requested by such Person, and all exhibits to the extent requested by such Person
(including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission, provided that any such item which is available on the EDGAR system (or successor thereto) need not be furnished in
physical form. 
 (g)     Subject to the terms of this Agreement, the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto, except after the giving of
any notice pursuant to Section 3(d). 
 (h)     Prior to any resale of Registrable Securities by a Holder, use its
commercially reasonable efforts to register or qualify or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the Registration or qualification) of such Registrable Securities for the resale by
the Holder under the securities or Blue Sky laws of such jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness
Period and to do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement, provided that the Company shall not be required to qualify
generally to do business in any jurisdiction where it is not then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such
jurisdiction. 
 (i)     If requested by a Holder, cooperate with such Holder to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by the Settlement Agreement, of all restrictive legends, and
to enable such Registrable Securities to be in such denominations and registered in such names as any such Holder may request. 
 (j)
    Upon the occurrence of any event contemplated by Section 3(d), as promptly as reasonably possible under the circumstances taking into account the Company’s good faith assessment of any adverse consequences to the
Company and its shareholders of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration Statement or a supplement to the related Prospectus or any document incorporated or
deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Holders in accordance with clauses (iii) through (vi)
of Section 3(d) above to suspend the use of any 

  
 6 

 
Prospectus until the requisite changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will use its best efforts to ensure that the use of
the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled to exercise its right under this Section 3(j) to suspend the availability of a Registration Statement and Prospectus, subject to the payment of partial
liquidated damages otherwise required pursuant to Section 2(d), for a period not to exceed 60 calendar days (which need not be consecutive days) in any 12-month period. 

(k)     Otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the
Commission under the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus, including any supplement or amendment thereof, with the Commission pursuant to Rule 424 under the
Securities Act, promptly inform the Holders in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Holders are required to deliver a Prospectus in
connection with any disposition of Registrable Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder. 

(l)     The Company may require each selling Holder to furnish to the Company a certified statement as to the number of
shares of Common Stock beneficially owned by such Holder and, if required by the Commission, the natural persons thereof that have voting and dispositive control over the shares. During any periods that the Company is unable to meet its obligations
hereunder with respect to the registration of the Registrable Securities solely because any Holder fails to furnish such information within three Trading Days of the Company’s request, any liquidated damages that are accruing at such time as to
such Holder only shall be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the Company. 

4.     Registration Expenses. All fees and expenses incident to the performance of or compliance with, this
Agreement by the Company shall be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation,
(i) all registration and filing fees (including, without limitation, fees and expenses of the Company’s counsel and independent registered public accountants) (A) with respect to filings made with the Commission, (B) with respect
to filings required to be made with any Trading Market on which the shares of Common Stock are then listed for trading, and (C) in compliance with applicable state securities or Blue Sky laws reasonably agreed to by the Company in writing

and the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange as required hereunder. In no event shall the Company be responsible for any broker or similar commissions of any Holder or,
except to the extent provided for in the Settlement Agreement, any legal fees or other costs of the Holders.

(a)     Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement,
indemnify and hold harmless each Holder, the officers, directors, members, partners, agents, brokers (including brokers who offer and sell Registrable Securities as principal as a result of a pledge or any failure to perform under a margin call),

preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto, in light of
the circumstances under which they were made) not misleading or (2) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or regulation thereunder, in connection with
the performance of its obligations under this Agreement, except to the extent, but only to the extent, that (i) such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by
such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder

connection with the transactions contemplated by this Agreement of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified person and shall survive the
transfer of any Registrable Securities by any of the Holders in accordance with Section 6(f). 
 (b)
    Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning

this Section 5 and the amount of any damages such Holder has otherwise been required to pay by reason of such untrue statement or omission) received by such Holder upon the sale of the Registrable Securities included in the Registration
Statement giving rise to such indemnification obligation. 
 (c)     Conduct of Indemnification Proceedings. If
any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the
“Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and
expenses incurred in connection with defense thereof, provided that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to
the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party. 

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of such 

  
 8 

 
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses, (2) the Indemnifying Party shall have failed promptly to assume the
defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding, or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and
the Indemnifying Party, and counsel to the Indemnified Party shall reasonably believe that a material conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if
such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable
fees and expenses of no more than one separate counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall
not be unreasonably withheld or delayed. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such
settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding. 

Subject to the terms of this Agreement, all reasonable fees and expenses of the Indemnified Party (including reasonable fees
and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written
notice thereof to the Indemnifying Party, provided that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses applicable to such actions for which such Indemnified Party is finally
determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) not to be entitled to indemnification hereunder. 

(d)     Contribution. If the indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party
or insufficient to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party, in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party
shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a
party as a result of any Losses shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other fees or expenses incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. 

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were
determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. In no event shall the contribution obligation of a Holder of
Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such Holder in connection with any claim relating to this Section 5 and the amount of any damages such Holder has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation. 

The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying
Parties may have to the Indemnified Parties. 
 6.     Miscellaneous. 

(a)     Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations
under this Agreement, each Holder or the Company, as the case may be, in addition to being 

  
 9 

 
entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, shall be entitled to specific performance of its rights under this Agreement. Each of the
Company and each Holder agrees that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action
for specific performance in respect of such breach, it shall not assert or shall waive the defense that a remedy at law would be adequate. 

(b)     No Piggyback on Registrations; Prohibition on Filing Other Registration Statements. Neither the Company nor
any of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in any Registration Statements other than the Registrable Securities. The Company shall not file any other registration
statements until all Registrable Securities are registered pursuant to a Registration Statement that is declared effective by the Commission, provided that this Section 6(b) shall not prohibit the Company from filing amendments to registration
statements filed prior to the date of this Agreement so long as no new securities are registered on any such existing registration statements. 

(c)     Discontinued Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon
receipt of a notice from the Company of the occurrence of any event of the kind described in Section 3(d)(iii) through (vi), such Holder will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until
it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company will use its best efforts to ensure that the use of the
Prospectus may be resumed as promptly as is practicable. The Company agrees and acknowledges that any periods during which the Holder is required to discontinue the disposition of the Registrable Securities hereunder shall be subject to the
provisions of Section 2(d). 
 (d)     Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and the Holders of 50.1%
or more of the then outstanding Registrable Securities (for purposes of clarification, this includes any Registrable Securities issuable upon exercise or conversion of any Security), provided that, if any amendment, modification or waiver
disproportionately and adversely impacts a Holder (or group of Holders), the consent of such disproportionately impacted Holder (or group of Holders) shall be required. If a Registration Statement does not register all of the Registrable Securities
pursuant to a waiver or amendment done in compliance with the previous sentence, then the number of Registrable Securities to be registered for each Holder shall be reduced pro rata among all Holders and each Holder shall have the right to designate
which of its Registrable Securities shall be omitted from such Registration Statement. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of a
Holder or some Holders and that does not directly or indirectly affect the rights of other Holders may be given only by such Holder or Holders of all of the Registrable Securities to which such waiver or consent relates; provided,
however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the first sentence of this Section 6(d). No consideration shall be offered or paid to any Person to
amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration also is offered to all of the parties to this Agreement. 

(e)     Notices. Any and all notices or other communications or deliveries required or permitted to be provided
hereunder shall be in writing and shall be deemed given and effective on the earliest of: (a) the time of transmission, if such notice or communication is delivered via email attachment at the email address as set forth on the signature pages
attached hereto at or prior to 5:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the time of transmission, if such notice or communication is delivered via email attachment at the email address as set forth on the
signature pages attached hereto on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (c) the second (2nd)Trading Day following the date of
mailing, if sent by U.S. nationally recognized overnight courier service or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature
pages attached hereto. To the extent that any notice provided pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding the Company or any Subsidiaries, the
Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. 

(f)     Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and
permitted assigns of each of the parties and shall inure to the benefit of each Holder. The Company 

  
 10 

 
may not assign (except by merger) its rights or obligations hereunder without the prior written consent of all of the Holders of the then outstanding Registrable Securities. Any Purchaser may
assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Securities, provided that such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions
of this Agreement and the Settlement Agreement that apply to the “Purchasers” and Maxim. 
 (g)     No
Inconsistent Agreements. Neither the Company nor any of its Subsidiaries has entered, as of the date hereof, nor shall the Company or any of its Subsidiaries, on or after the date of this Agreement, enter into any agreement with respect to its
securities, that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Except as set forth on Schedule 6(i), neither the Company nor any of its
Subsidiaries has previously entered into any agreement granting any registration rights with respect to any of its securities to any Person that have not been satisfied in full. 

(h)     Execution and Counterparts. This Agreement may be executed in two or more counterparts, all of which when
taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In
the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party
executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. 

(i)     Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this
Agreement shall be determined in accordance with the provisions of the Settlement Agreement. 
 (j)     Cumulative
Remedies. The remedies provided herein are cumulative and not exclusive of any other remedies provided by law. 

(k)     Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of
competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated,
and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby
stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or
unenforceable. 
 (l)     Headings. The headings in this Agreement are for convenience only, do not constitute a
part of the Agreement and shall not be deemed to limit or affect any of the provisions hereof. 
 (m)     Independent
Nature of Holders’ Obligations and Rights. The obligations of each Holder hereunder are several and not joint with the obligations of any other Holder hereunder, and no Holder shall be responsible in any way for the performance of the
obligations of any other Holder hereunder. Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any Holder pursuant hereto or thereto, shall be deemed to constitute the Holders as a
partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Holders are in any way acting in concert or as a group or entity with respect to such obligations or the transactions contemplated by
this Agreement or any other matters, and the Company acknowledges that the Holders are not acting in concert or as a group, and the Company shall not assert any such claim, with respect to such obligations or transactions. Each Holder shall be
entitled to protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding for such purpose. The use of
a single agreement with respect to the obligations of the Company contained was solely in the control of the Company, not the action or decision of any Holder, and was done solely for the convenience of the Company and not because it was required or
requested to do so by any Holder. It is expressly understood and agreed that each provision contained in this Agreement is between the Company and a Holder, solely, and not between the Company and the Holders collectively and not between and among
Holders.

 Annex A 

Plan of Distribution 

Each Selling Shareholder (the “Selling Shareholder”) of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or
trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Shareholder may use any one or more of the following methods when selling securities: 

 

	 	•	 	 ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

  

	 	•	 	 block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell
a portion of the block as principal to facilitate the transaction; 

  

	 	•	 	 purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

 

	 	•	 	 an exchange distribution in accordance with the rules of the applicable exchange; 

 

	 	•	 	 privately negotiated transactions; 

 

	 	•	 	 settlement of short sales; 

 

	 	•	 	 in transactions through broker-dealers that agree with the Selling Shareholders to sell a specified number of
such securities at a stipulated price per security; 

  

	 	•	 	 through the writing or settlement of options or other hedging transactions, whether through an options exchange
or otherwise; 

  

	 	•	 	 a combination of any such methods of sale; or 

 

	 	•	 	 any other method permitted pursuant to applicable law. 

The Selling Shareholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as
amended (the “Securities Act”), if available, rather than under this prospectus. 
 Broker-dealers engaged by the Selling
Shareholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Shareholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the
purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a
principal transaction a markup or markdown in compliance with FINRA Rule 2121. 
 In connection with the sale of the securities or interests
therein, the Selling Shareholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling
Shareholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Shareholders may also enter into
option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus,
which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). 

  
 15 

 The Selling Shareholders and any broker-dealers or agents that are involved in selling the
securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities
purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Shareholders has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly,
with any person to distribute the securities. 
 The Company is required to pay certain fees and expenses incurred by the Company incident
to the registration of the securities. The Company has agreed to indemnify the Selling Shareholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act. 

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling
Shareholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in
compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any
other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not
be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with. 

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not
simultaneously engage in market making activities with respect to the shares of Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Shareholders will
be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the shares of Common Stock by the Selling Shareholders or any other
person. We will make copies of this prospectus available to the Selling Shareholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172
under the Securities Act). 
 SELLING SHAREHOLDERS 

The shares of Common Stock being offered by the selling shareholders are those previously issued to the selling shareholders, and those
issuable to the selling shareholders, upon conversion of the preferred stock. For additional information regarding the issuances of those shares of Common Stock, see “Private Placement of Preferred Stock” above. We are
registering the shares of Common Stock in order to permit the selling shareholders to offer the shares for resale from time to time. Except for the ownership of the shares of preferred stock and the underlying shares, the selling shareholders have
not had any material relationship with us within the past three years. 
 The table below lists the selling shareholders and other
information regarding the beneficial ownership of the shares of Common Stock by each of the selling shareholders. The second column lists the number of shares of Common Stock beneficially owned by each selling shareholder, based on its ownership of
the shares of Common Stock and warrants, as of             , 2022, assuming conversion of the preferred stock held by the selling shareholders on that date, without regard to any
limitations on exercises. 
 The third column lists the shares of Common Stock being offered by this prospectus by the selling shareholders.

 In accordance with the terms of a registration rights agreement with the selling shareholders, this prospectus generally covers the
resale of the number of shares of Common Stock issued to the selling shareholders in the “Private Placement of Preferred Stock” described above, without regard to any limitations on the conversion of the preferred stock. The
fourth column assumes the sale of all of the shares offered by the selling shareholders pursuant to this prospectus. 

  
 16 

 Under the terms of the preferred stock, a selling shareholder may not convert the preferred
stock to the extent such conversion would cause such selling shareholder, together with its affiliates and attribution parties, to beneficially own a number of shares of Common Stock which would exceed 19.99% of our then outstanding shares of Common
Stock following such exercise, excluding for purposes of such determination shares of Common Stock issuable upon conversion of such shares which have not been converted. The number of shares in the second and fourth columns do not reflect this
limitation. The selling shareholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

	 	Re:	Amended
    Proposed Private Placement Financing

 

Dear
Marco Alfonsi

 

1.
As you know, on March 11, 2022, CAN B Corp. (“CANB”), entered into a Proposed Private Placement Financing Agreement (the
March 11th Agreement) with J.H. Darbie & Co., Inc. (“Darbie”).. This amended letter will replace the
March 11th Agreement and confirm the current understanding and agreement (the “Agreement”) between Darbie
and CANB as follows: Engagement. The Company hereby engages Darbie on a nonexclusive basis to conduct a review of the business
and financial condition of the Company and its proposed Private Placement financing (“Offering”) to be used in connection
with the Offering, with a view toward possibly participating as a sales agent in the private placement of Convertible Note (the “Securities”)
of the Company to a limited number of investors (“Investors”) to be introduced to the Company by Darbie and other
authorized securities broker-dealers that are members in good standing of The Financial Industry Regulatory Authority, Inc. (“FINRA”).
Such private placement will be referred to as the “Transaction.” Currently, the Company plans to raise up to $1,125,000.
The number and price of the Securities the Company will ultimately agree to sell and the Investors to whom the Securities are sold, pursuant
to the Subscription Documents (defined below), are entirely within the Company’s discretion.

 

2.
Offering Materials. The Company will prepare and deliver to Darbie copies of subscription materials including the appropriate
disclosure documents, relating to, among other things, the Company, the Securities, and the terms of the Offering. These subscription
materials, including all exhibits thereto and all documents delivered therewith and incorporated by reference therein, are referred to
herein as the “Offering Materials,” unless the subscription material (including exhibits or documents) is supplemented
or amended in accordance with this Agreement, in which event, the term “Offering Materials” refers to such subscription
material, exhibits, and documents as so supplemented or amended from and after the time of its delivery to Darbie. The Company is responsible
for reviewing and finally approving the Offering Materials and all related documents used by Darbie in the Transaction.

 

(a)
Darbie’s Role. Darbie hereby accepts the engagement described herein and, in that connection, agrees to assist and advise
the Company respecting the terms of the Transaction.

 

3.
Due Diligence. It is understood that Darbie’s assistance in the Transaction will be subject to the completion, satisfactory
to Darbie in its sole discretion, of its Due Diligence and the approval of Darbie’s supervisory personnel of the undertaking. Darbie
will have the right, in its sole discretion, to terminate this Agreement if the outcome of the Due Diligence is not satisfactory to Darbie
or if approval of its supervisory personnel is not obtained (“Early Termination”).

in any placement of the Company’s securities directly or indirectly resulting from Darbie’s introductions to prospective
investors. Such consideration paid in cash shall be paid directly to Darbie out of escrow, as and when such consideration is paid to

(b)
As further compensation for the services to be rendered by Darbie hereunder, the Company shall issue to Darbie warrants to purchase that
number of Securities that equals 8% of the number of Securities sold by Darbie in the offering. The warrants shall have the same terms
and exercise price of the warrants purchased by investors in this offering. The warrants shall be exercisable immediately after the date
of issuance, shall have participating registration rights and shall expire 5 years after the date of issuance, unless otherwise extended
by the Company. The warrants shall include a cashless exercise provision and will be non-redeemable and provide for automatic exercise
upon expiration. The warrants shall be transferable, subject only to the securities laws, by the holders thereof.

 

(c)
The Company’s obligations under this section will survive the termination or expiration of this Agreement.

 

9.
Indemnity. In addition to the fees provided for above, the parties agree to the following indemnification provisions:

 

(a)
The Company agrees to indemnify and hold harmless Darbie and its affiliates, and their respective directors, officers, employees, agents,
and controlling persons (each such person, including Darbie, an “Indemnified Party”), from and against any losses,
claims, damages, and liabilities, joint or several (collectively, the “Damages”), to which an Indemnified Party may
become subject in connection with or otherwise relating to or arising from: (i) any Transaction or the engagement of, or performance
of services by, an Indemnified Party hereunder; or (ii) any untrue statement of a material fact or omission to state a material fact
necessary in order to make the statements made, in the light of the circumstances under which they were made, not misleading. The Company
agrees to will reimburse each Indemnified Party for all fees and expenses (including the fees and expenses of counsel) (collectively,
“Expenses”) as incurred in connection with investigating, preparing, pursuing, or defending any threatened or pending
claim, action, proceeding, or investigation (collectively, the “Proceedings”) arising therefrom, whether or not the
Indemnified Party is a formal party to such Proceeding; provided, that the Company will not be liable to any Indemnified Party
to the extent that any Damages are found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from
the gross negligence or willful misconduct of the Indemnified Party seeking indemnification hereunder. The Company also agrees that no
Indemnified Party will have any liability (whether direct or indirect, in contract, tort or otherwise) to the Company or any person asserting
claims on the Company’s behalf arising out of or in connection with any Transactions or the engagement of, or performance of services
by, any Indemnified Party thereunder, except to the extent that any Damages are found in a final, non-appealable judgment by a court
of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Indemnified Party.

 

(b)
If for any reason, other than in accordance with this Agreement, the foregoing indemnity is unavailable to an Indemnified Party or insufficient
to hold an Indemnified Party harmless, then the Company will contribute to the amount paid or payable by an Indemnified Party as a result
of Damages (including all Expenses incurred) such proportion as is appropriate to reflect the relative benefits to the Company and its
stockholders, on the one hand, and Darbie, on the other hand, in connection with the matters covered by this Agreement. If the foregoing
allocation is not permitted by applicable law, the Company will contribute to the amount paid or payable by an Indemnified Party as a
result of Damages (including all Expenses incurred) such proportion as is appropriate to reflect not only the relative benefits but also
the relative faults of the parties as well as any relevant equitable considerations. The Company agrees that for purposes of this section,
the relative benefits to the Company and its stockholders and Darbie in connection with the matters covered by this Agreement will be
deemed to be in the same proportion that the total value paid or received or to be paid or received by the Company and its stockholders
in connection with the Transactions, whether or not consummated, bears to the fees paid to Darbie under this Agreement; provided,
that in no event will the total contribution of all Indemnified Parties to all Damages exceed the amount of fees actually received and
retained by Darbie hereunder (excluding any amounts received by Darbie for performing Due Diligence).

(c)
The Company agrees not to enter into any waiver, release, or settlement of any Proceedings (whether or not Darbie or any other Indemnified
Party is a formal party to such Proceedings) in respect of which indemnification may be sought hereunder without the prior written consent
of Darbie (which consent will not be unreasonably withheld), unless the waiver, release, or settlement includes an unconditional release
of Darbie and each Indemnified Party from all liability arising out of the Proceeding.

 

(d)
The indemnity, reimbursement, and contribution obligations of the Company hereunder will be in addition to any liability that the Company
may otherwise have to any Indemnified Party and will be binding upon and inure to the benefit of any successors, assigns, heirs, and
personal representatives of the Company or an Indemnified Party.

 

(e)
The provisions of this indemnification section will survive the modification, termination, or expiration of this Agreement.

 

10.
Governing Law. This Agreement will be governed by and construed and interpreted in accordance with the laws of the state of New

will be resolved through arbitration.

 

11.
Confidentiality. Except for disclosure to the Investors and as otherwise required by law, this Agreement and the services and
advice to be provided by Darbie hereunder will not be disclosed to third parties without Darbie’s prior written permission. Notwithstanding
the foregoing, Darbie will be permitted to advertise the services it provided in connection with the Transaction subsequent to the consummation
of the Transaction.

 

12.
Compliance by Darbie. Notwithstanding the Company’s obligations in subsection 7(f), Darbie agrees that it will comply with
the applicable terms and conditions of the Securities Act of 1933, as amended, to ensure that the sale of Securities by it contemplated
by this Agreement will be exempt from the registration requirements, and Darbie will otherwise comply with applicable securities laws
in connection with the services it provides pursuant to this Agreement.

 

13.
Authorization. Each of the Company and Darbie represent and warrant that it has all requisite power and authority to enter into
and carry out the terms and provisions of this Agreement and the execution, delivery, and performance of this Agreement does not breach
or conflict with any agreement, document, or instrument to which it is a party or bound.
