 PROMISSORY NOTE 

May 1, 2020 
 Principal Amount: $405,000 

Kaleyra, Inc., f.k.a. GigCapital, Inc., a Delaware corporation (the “Maker”), promises to pay to the order of Chardan Capital
Markets, LLC, or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of up to four hundred and five thousand dollars ($405,000) in lawful money of the United States of America, on the terms
and conditions described below from the date hereof (the “Issuance Date”). All payments on this Promissory Note (the “Note”) shall be made by check or wire transfer of immediately available funds or as otherwise
determined by the Maker to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note. 

1.    Principal. The principal balance of this Note shall be payable by the Maker on May 1, 2023 (the
“Maturity Date”). Pursuant to the provisions of Section 4 hereof, the unpaid principal balance may be prepaid at any time, at the election of the Maker. Under no circumstances shall any individual, including but not limited to
any executive officer, director, employee or stockholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder. 

2.    Interest. Subject to the provisions of Sections 4 and 10 hereof, interest shall accrue on the unpaid principal
balance of this Note at the rate of five percent (5%) per annum from the Issuance Date. Interest shall be payable by the Maker in arrears to the Payee on March 15, June 15, September 15 and December 15 of each year while this
Note remains outstanding (each, an “Interest Payment Date”). The first Interest Payment Date shall be June 15, 2020. 

3.    Optional Conversion. 

(a)     At the option of the Payee, at any time prior to payment in full of the unpaid principal balance of this Note, the
Payee may elect to convert all or any portion of the unpaid principal balance of this Note into a number of shares of common stock of the Maker (the “Common Stock”) equal to: (i) the portion of the unpaid principal amount of
the Note being converted pursuant to this Section 3, divided by (ii) $7.5700 (the “Conversion Price”). 
 (b)
    Upon any complete or partial conversion of the unpaid principal amount of this Note (i) such unpaid principal amount shall be so converted and such converted portion of this Note shall be deemed to have been fully paid
and satisfied, (ii) the Payee shall surrender and deliver this Note, duly endorsed, to the Maker or such other address which the Maker shall designate against delivery of the Common Stock, (iii) the Maker shall promptly deliver a new duly
executed Note to the Payee in the principal amount that remains outstanding, if any, after any such conversion and (iv) in exchange for all or any portion of the surrendered Note described in Section 3(a), the Maker shall deliver to Payee,
at the option of the Maker: (A) the Common Stock, which shall bear such legends as are required, in the opinion of counsel to the Maker or by any other agreement between the Maker and the Payee and applicable state and federal securities laws,
(B) an amount in cash equal to the product of (x) the number of shares of Common Stock to be delivered, multiplied by (y) the closing price for the Common Stock on the trading day that notice of conversion was delivered to the Maker
(the “Cash Conversion Amount”), or (C) a combination of Common Stock and cash equal to the Cash Conversion Amount. If the date on which the Payee chooses to exercise this right in accordance with the provisions of
Section 3 hereof (the “Conversion Date”) occurs on the same day as an Interest Payment Date, the Maker shall also pay the Payee a fee in the amount equal to the interest that would have become due and payable pursuant to
Section 2 hereof on the relevant Interest Payment Date. 
  

  
 1 

 (c)     Upon exercise of this conversion, the Maker shall promptly (but
in no event later than two business days after the Conversion Date), upon the request of the Payee, credit such aggregate number of shares of Common Stock to which the Payee is entitled pursuant to such exercise to the Payee’s or its
designee’s balance account with The Depository Trust Company (“DTC”) through its Deposit Withdrawal Agent Commission system, or if the Maker’s transfer agent is not participating in the Fast Automated Securities Transfer
Program (the “FAST Program”) or if the certificates are required to bear a legend regarding restriction on transferability, issue and dispatch by overnight courier, a certificate, registered in the Maker’s share register in the
name of the Payee or its designee, for the number of shares of Common Stock to which the Payee is entitled pursuant to such exercise. The Payee, or any natural person or legal entity permissibly so designated by the Payee to receive the shares of
Common Stock, shall be deemed to have become the holder of record of such shares of Common Stock as of the Conversion Date, irrespective of the date such shares of Common Stock are credited to the Payee’s DTC account or the date of delivery of
the certificates evidencing such shares of Common Stock, as the case may be. 
 (d)     If by the close of the second
business day after the Conversion Date, the Maker fails to deliver to the Payee a certificate representing the required number of shares of Common Stock in the manner required pursuant to Section 3(c) hereof or fails to credit the Payee’s
balance account with DTC for such number of shares of Common Stock to which the Payee is entitled, and if after such second business day and prior to the receipt of such shares of Common Stock, the Payee purchases (in an open market transaction or
otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Payee of shares which the Payee anticipated receiving upon such exercise (a “Buy-In”), then the Maker shall,
within two business days after the Payee’s request and in the Payee’s sole discretion, either (i) pay in cash to the Payee an amount equal to the Payee’s total purchase price (including brokerage commissions, if any) for the
shares of Common Stock so purchased, at which point the Maker’s obligation to deliver such certificate (and to issue such shares of Common Stock) shall terminate or (ii) promptly honor its obligation to deliver to the Payee a certificate
or certificates representing such shares of Common Stock and pay cash to the Payee in an amount equal to the excess (if any) of Payee’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased
in the Buy-In over the product of (A) the number of shares of Common Stock purchased in the Buy-In, times (B) the closing price of a share of Common Stock on
the Conversion Date. 
 (e)     In connection with the conversion of all or any portion of the unpaid principal balance
of this Note into Common Stock, neither the Maker nor any person acting on its behalf will take any action which would result in the Common Stock being exchanged by the Maker other than with the Maker’s existing security holders exclusively
where no commission or other remuneration is paid or given directly or indirectly for soliciting such exchange. 
 (f)
    The Maker shall pay any and all issue and other taxes that may be payable with respect to any issue or delivery of the Common Stock and/or cash upon conversion of this Note pursuant hereto; provided, however, that the Payee
shall pay any transfer taxes resulting from any transfer requested by the Payee in connection with any such conversion. 
 (g)
    Notwithstanding anything herein to the contrary, the Maker shall not effect any conversion of this Note, and the Payee shall not have the right to convert any portion of this Note, to the extent that, the Payee (together with
the Payee’s affiliates, and any other person whose beneficial ownership of Common Stock would be aggregated with the Payee’s for purposes of Section 13(d) or Section 16 of the United States Exchange Act of 1934, as amended (the
“Exchange Act”) and the applicable regulations of the Commission, including any “group” of which the Payee is a member (the foregoing, the “Attribution Parties”)) would beneficially own a number of shares
of Common Stock in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Payee and its Attribution Parties shall include the number of
shares of Common Stock issuable upon conversion of this Note, but shall exclude the number of shares of Common Stock which are issuable upon exercise or conversion of the unexercised or unconverted portion of any other securities of the Maker
(including any warrants) beneficially owned by the Payee or any of its Attribution Parties that are subject to a limitation on conversion or exercise similar to the limitation contained herein. For purposes of this

  
 2 

 
Section 3(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the applicable regulations of the Commission. In addition, for purposes
hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and the applicable regulations of the Commission. For purposes of this Section 3(d), in determining the number of outstanding shares of Common Stock,
the Payee may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (A) the Maker’s most recent periodic or annual filing with the Commission, as the case may be, (B) a more recent
public announcement by the Maker that is filed with the Commission, or (C) a more recent notice by the Maker or the Maker’s transfer agent to the Payee setting forth the number of shares of Common Stock then outstanding. Upon the written
request of the Payee (which may be by email), the Maker shall, within three (3) business days, confirm in writing to the Payee (which may be via email) the number of shares of Common Stock then outstanding. In any case, the number of
outstanding shares of Common Stock shall be determined after giving effect to any actual conversion or exercise of securities of the Maker, including shares of Common Stock, by the Payee or its Attribution Parties since the date as of which such
number of outstanding shares of Common Stock was last publicly reported or confirmed to the Payee. The “Beneficial Ownership Limitation” shall initially be 4.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock pursuant to Section 3(b) hereof. The Maker shall be entitled to rely on representations made to it by the Payee regarding its Beneficial Ownership Limitation. 

(h)     Notwithstanding the foregoing, by written notice to the Maker, which will not be effective until the sixty-first
(61st) day after such notice is delivered to the Maker, the Payee may reset the Beneficial Ownership Limitation percentage to a higher or lower percentage, not to exceed 19.9% of the number of shares of the Common Stock outstanding immediately after
giving effect to the issuance of shares of Common Stock pursuant to Section 3(b) hereof. Upon such a change by the Payee of the Beneficial Ownership Limitation, the Beneficial Ownership Limitation may not be further amended by the Payee without
first providing the minimum notice required by Section 3(e) hereof. Notwithstanding the foregoing, at any time following notice of a Fundamental Change, the Payee may waive and/or change the Beneficial Ownership Limitation effective immediately
upon written notice to the Maker and may reinstitute the Beneficial Ownership Limitation at any time thereafter effective immediately upon written notice to the Maker. 

4.    Optional Redemption and Interest Rate Adjustment.

(a)     Optional Redemption. At the option of the Maker, at any time prior to payment in full of the unpaid
principal balance of this Note, the Maker may elect to redeem: (i) the unpaid principal balance of this Note, or (ii) a portion thereof, together with any accrued but unpaid interest (the “Redemption Amount”). At least
twenty (20) days before the date on which the Maker elects to redeem in accordance with the provisions of this Section 4 (the “Redemption Date”), the Maker shall give the Payee written notice of its intention to exercise
this right. On the Redemption Date, the Maker shall repay to the Payee the Redemption Amount. 
 (b)     Interest
Rate Adjustment. Subject to the provisions of Section 10 hereof, in the event that any portion of this Note is redeemed prior to May 1, 2021, all previously paid and accrued and unpaid interest on this Note from the Issuance Date to
the Redemption Date shall be recalculated at the time of prepayment as if Section 2 of this Note was amended to replace “five percent (5%)” with “three percent (3%)” and the excess interest shall be deducted from the
Redemption Amount. In the event that any portion of this Note is redeemed prior to May 1,2022, all previously paid and accrued and unpaid interest on this Note from the Issuance Date to the Redemption Date shall be recalculated at the time of
prepayment as if Section 2 of this Note was amended to replace “five percent (5%)” with “four percent (4%)” and the excess interest shall be deducted from the Redemption Amount. 

5.    Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the
collection of any sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges, the accrued but unpaid interest and finally to the reduction of the unpaid principal balance
of this Note.

 6.    Reservation of Underlying Shares. 

(a)    Reservation. So long as this Note remains outstanding, the Maker covenants and agrees that at all times the
Maker shall reserve and keep available for the Payee out of its authorized and unissued shares of Common Stock, free from pre-emptive rights or any other actual contingent purchase rights of persons other than
the Payee, one hundred percent (100%) of the maximum number of shares of Common Stock issuable upon conversion of this Note (the “Underlying Shares”). Any shares of Common Stock issued to the Payee upon conversion of this Note shall
be subject to the provisions of the registration rights agreement, dated May 1, 2020, between the Maker and the Payee, regarding the ownership of Registrable Securities as defined therein. 

7.    Fundamental Change. Upon the occurrence of: (i) a Change of Control, (ii) the sale of all or
substantially all the assets of the Maker (determined on a consolidated basis) to another person or group or (iii) the approval by the stockholders of the Maker of a plan of liquidation or dissolution or other insolvency event (each event
described in (i) to (iii) above, a “Fundamental Change”), the Maker shall repurchase this Note at a price equal to: (i) the principal amount of this Note that remains unpaid plus any accrued but unpaid interest up to the
date of repurchase (the “Repurchase Price”) within five (5) days of such Fundamental Change. At least twenty (20) days prior to the relevant Fundamental Change, the Maker shall deliver written notice to the Payee
describing in reasonable detail the terms of such Fundamental Change. 
 For the purposes of this Section 7, a “Change of Control”
will occur (i) if any person or group of persons (other than the Maker or the Payee or a person that directly or indirectly controls, is controlled by, or is under common control with, the Maker or the Payee) becomes the beneficial owner,
directly or indirectly, of securities possessing the power to direct or cause the direction of the management and policies of the Maker, whether through the ownership of capital stock, by contract or otherwise, or (ii) upon the consummation of
any transaction (including, without limitation, any merger or consolidation) the result of which is that any person or any group (other than one or more of the Maker’s Subsidiaries) becomes the beneficial owner, directly or indirectly, of more
than fifty percent (50%) of the voting stock of the Maker, measured by voting power rather than number of shares. 

8.    Negative Pledge. The Maker will not, and will not permit any other member of the Group to, create, assume or
permit to subsist any security interest over any of the Maker’s properties or assets, including, without limitation, the issued share capital of any direct Subsidiary of the Maker, other than a Permitted Security Interest. 

For the purposes of this Section 8: 

“control” means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of a
person, whether through the ability to exercise voting power, by contract or otherwise. “controlling” and “controlled” have meanings correlative thereto.

2.1.1     Registration Obligation. Within twenty (20) business days from the date of execution of this
Agreement and the Settlement Agreement, the Company shall prepare and file with (or confidentially submit to) the Commission a registration statement on Form S-1 or any similar long-form registration statement
that may be available to the Company at such time (the “Form S-1”) for the purpose of registering the resale of the Registrable Securities (the “Resale Registration
Statement”) and shall use its best efforts to cause the Resale Registration Statement to be declared effective within thirty (30) days of filing with the Commission; or, if the Commission reviews the Resale Registration Statement,
within sixty (60) days of filing with the Commission. After its date of initial effectiveness, the Company shall use its best efforts to keep such Resale Registration Statement effective to effect the Registration to permit the sale of
Registrable Securities in accordance with the intended plan of distribution thereof as expeditiously as practicable until such time as the securities to be sold by Cowen and Chardan are no longer Registrable Securities. 

2.1.2     Effective Registration. Notwithstanding any other part of this Agreement, a Registration pursuant to
Section 2.1.1 will not count as a Registration unless and until (i) the Registration Statement filed with the Commission in connection with the Registration has been declared effective by the Commission, and
(ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, that if, after such Registration Statement has been declared effective, the offering of Registrable Securities is interfered
with by any stop order or injunction of the Commission or any other governmental agency or court, the Registration Statement will be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed,
rescinded or otherwise terminated, and (ii) Cowen or Chardan, as the case may be, with respect to the Registrable Securities being offered by it hereunder, thereafter affirmatively elects to continue with such Registration and accordingly
notifies the Company in writing of such election, which notice shall be received by the Company not later than five (5) days after the removal of any such stop order or injunction; provided, further, that the Company shall not be
obligated to file a second Registration Statement until a Registration Statement that has been previously filed pursuant to Section 2.1.1 becomes effective or is terminated. 

2.1.3     Withdrawal. Each of Cowen and Chardan shall have the right to withdraw from a Registration under
Section 2.1.1 for any or no reason whatsoever upon written notification to the Company of its intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission
with respect to the Registration of the Registrable Securities being offered by it. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Registration
under Section 2.1.1 prior to its withdrawal under this Section 2.1.3. 

2.2    Piggy-Back Registration. 

2.2.1     Piggy-Back Rights. If at any time on or after the date hereof the Company proposes to file a Registration
Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account or for stockholders
of the Company for their account (or by the Company and by stockholders of the Company), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or
offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company, or (iv) for a dividend reinvestment plan, then the Company shall
(x) give written notice of such proposed filing to Cowen and Chardan as soon as practicable but in no event less than ten (10) days before the anticipated filing date, which notice shall describe the amount and type of securities to be
included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering, and (y) offer to Cowen and Chardan in such notice the opportunity to register the
sale of such number of shares of Registrable Securities as Cowen and/or Chardan may request in writing within five (5) days following receipt of such notice (a “Piggyback Registration”). The Company shall, in good faith,
cause such Registrable Securities to be included in such Registration and shall use its best efforts to cause the managing 

  
 3 

 
Underwriter(s) of a proposed Underwritten Offering to permit the Registrable Securities requested to be included in a Piggyback Registration on the same terms and conditions as any similar
securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. If Cowen and/or Chardan proposes to distribute Registrable Securities through a
Piggy-Back Registration that involves an Underwriter(s) it shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Piggyback Registration. 

2.2.2    Reduction of Piggyback Registration. If the managing Underwriter(s) for a Piggyback Registration that is
to be an Underwritten Offering, in good faith, advises the Company, Cowen and Chardan in writing that the dollar amount or number of securities which the Company desires to sell, taken together with (i) the Common Stock, if any, as to which
Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than Cowen and Chardan, (ii) the Registrable Securities as to which Registration has been requested under this
Section 2.2, and (iii) the Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggyback registration rights of other stockholders of the Company, exceeds the
maximum dollar amount or maximum number of equity securities that can be sold in such Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such
Underwritten Offering (such maximum dollar amount or maximum number of securities, as applicable, the “Maximum Number of Securities”), then: 

a) If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, the
Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the
foregoing clause (A), the Registrable Securities of Cowen and Chardan, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the
foregoing clauses (A) and (B), the Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggyback registration rights of other stockholders of the Company, which can be sold without exceeding the
Maximum Number of Securities; and 
 b) If the Registration is pursuant to a request by persons or entities other than Cowen or Chardan, then
the Company shall include in any such Registration (A) first, the Common Stock or other equity securities, if any, of such requesting persons or entities, other than Cowen and Chardan, which can be sold without exceeding the Maximum Number of
Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Cowen and/or Chardan, based on the number of Registrable Securities that each of
Cowen and Chardan have requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that each of Cowen and Chardan have requested to be included in such Underwritten Registration, which can be sold
without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Common Stock or other equity securities that the Company
desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the Common Stock or
other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum
Number of Securities. 
 2.2.3    Piggyback Registration Withdrawal. Each of Cowen and Chardan shall have the
right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter(s) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of
the Registration Statement filed with the Commission with respect to such Piggyback Registration. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written
contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in
this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.2.3. 

2.3    Registrations on Form S-3. Each of Cowen and Chardan may at any
time, and from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of its Registrable Securities on Form
S-3 or any similar short-form registration statement that may be available at such time (“Form S-3”). Within twelve (12) days of the
Company’s receipt of a written request from Cowen and/or Chardan for a Registration on Form S-3, the Company shall 

  
 4 

 
register all or such portion of Cowen’s and/or Chardan’s Registrable Securities, as the case may be, as are specified in such written request; provided, that the Company shall
not be obligated to effect any such Registration pursuant to Section 2.3 hereof if a Form S-3 is not available for such offering. 

2.4    Restrictions on Registration Rights. If (A) during the period starting with the date sixty
(60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration pursuant to
Section 2.1.1 and it continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) Cowen and/or Chardan has requested an Underwritten
Registration and the Company, Cowen and Chardan are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental to the Company
and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to Cowen and/or Chardan a certificate signed by the Chairman of the Board stating
that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of such Registration Statement. In
such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days; provided, that the Company may not defer its obligation in this manner more than once in any
12-month period. 
  

	 	3.	 REGISTRATION PROCEDURES. 

3.1    Filings; Information. Whenever the Company is required to effect the registration of any Registrable

approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable Cowen and/or Chardan to consummate the
disposition of such Registrable Securities in such jurisdictions; provided, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or take any action to

 3.4    Suspension of Sales; Adverse Disclosure.
Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, Cowen and Chardan shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented
or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the
Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would
require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to Cowen and Chardan,
delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose.
In the event the Company exercises its rights under the preceding sentence, Cowen and Chardan agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection
with any sale or offer to sell Registrable Securities. The Company shall immediately notify Cowen and Chardan of the expiration of any period during which it exercised its rights under this Section 3.4. 

3.5    Reporting Obligations. As long as Cowen or Chardan shall own Registrable Securities, the Company, at all
times while it shall be reporting under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant
to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish Cowen and/or Chardan with true and complete copies of all such filings. The Company further covenants that it shall take such further action as Cowen or Chardan may reasonably
request, all to the extent required from time to time to enable Cowen and/or Chardan to sell the Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the
Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request of Cowen and/or Chardan, the Company shall deliver to Cowen and/or Chardan a written certification of a duly
authorized officer as to whether it has complied with such requirements. 
  

	 	4.	 INDEMNIFICATION AND CONTRIBUTION. 

4.1    Indemnification by the Company. The Company agrees to indemnify, to the extent permitted by law, and hold
harmless Cowen, Chardan, their respective officers and directors, and each person who controls Cowen or Chardan (within the meaning of the Securities Act), from and against any expenses, losses, judgments, claims, damages or liabilities (including
reasonable attorney’s fees), whether joint or several, arising out of or based upon any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus, or any amendment or
supplement to any of them, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information
furnished in writing to the Company by Cowen or Chardan, as the case may be, expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities, their officers and directors, and each person who controls such
Underwriter (within the meaning of the Securities Act) on substantially the same basis as that of the indemnification provided above in this Section 4.1. 

4.2    Indemnification by Cowen or Chardan. In connection with any Registration Statement in which Cowen or Chardan
is participating, Cowen or Chardan shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the

  
 7 

 
extent permitted by law, shall, severally and not jointly, indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the
Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or
preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or
omission is contained in any information or affidavit so furnished in writing by Cowen or Chardan expressly for use therein; provided, that the liability of Cowen or Chardan shall be in proportion to and limited to the net proceeds received
by it from the sale of Registrable Securities pursuant to such Registration Statement. Cowen or Chardan, severally and not jointly, shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within
the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company. 

4.3    Conduct of Indemnification Proceedings. Any person entitled to indemnification herein shall (i) give
prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such
failure has not materially prejudiced the indemnifying party), and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the
indemnified party without its consent. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No
indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying
party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or
litigation. 
 4.4    Contribution. If the indemnification provided under Section 4.1
hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the
indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying
party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the 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 to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying
party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, that the liability of Cowen or Chardan under this Section 4.4
shall be limited to the amount of the net proceeds received by Cowen or Chardan in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to
include, subject to the limitations set forth in Sections 4.1-4.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or
proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation or by any other method of allocation, which does not take
account of the equitable considerations referred to in this Section 4.4. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution
pursuant to this Section 4.4 from any person who was not guilty of such fraudulent misrepresentation. 

4.5    Survival. The indemnification provided for under this Agreement shall remain in full force and effect
regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company, Cowen and Chardan also agree to make
such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s, Cowen’s or Chardan’s indemnification is unavailable for any reason.

 5.    UNDERWRITING AND DISTRIBUTION. 

5.1    Rule 144. The Company covenants that it shall file any reports required to be filed by it under the
Securities Act and the Exchange Act and shall take such further action as Cowen or Chardan may reasonably request, all to the extent required from time to time to enable Cowen and/or Chardan without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 under the Securities Act, as such rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission.

6.3    Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term
or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall
be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible that is valid and enforceable. 

6.4    Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an
original, and all of which taken together shall constitute one and the same instrument. 
 6.5    Entire
Agreement. This Agreement (including all agreements entered into pursuant hereto and all certificates and instruments delivered pursuant hereto and thereto) constitute the entire agreement of the parties with respect to the subject matter hereof
and supersede all prior and contemporaneous agreements, representations, understandings, negotiations and discussions between the parties, whether oral or written. 

6.6    Modifications and Amendments. Upon the written consent of the Company, Cowen and Chardan, compliance with
any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified. No course of dealing between Cowen, Chardan or the Company or any failure or
delay on the part of Cowen, Chardan or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of Cowen, Chardan or the Company. No single or partial exercise of any rights or
remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party. 

6.7    Titles and Headings. Titles and headings of sections of this Agreement are for convenience only and shall
not affect the construction of any provision of this Agreement. 
 6.8    Waivers and Extensions. Any party to
this Agreement may waive any right, breach or default which such party has the right to waive, provided that such waiver will not be effective against the waiving party unless it is in writing, is signed by such party, and specifically refers to
this Agreement. Waivers may be made in advance or after the right waived has arisen or the breach or default waived has occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a
waiver of any preceding or succeeding breach thereof nor of any other agreement or provision herein contained. No waiver or extension of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for
performance of any other obligations or acts. 
 6.9    Remedies Cumulative. In the event that the Company fails
to observe or perform any covenant or agreement to be observed or performed under this Agreement, Cowen and Chardan may proceed to protect and enforce their respective rights by suit in equity or action at law, whether for specific performance of
any term contained in this Agreement or for an injunction against the breach of any such term or in aid of the exercise of any power granted in this Agreement or to enforce any other legal or equitable right, or to take any one or more of such
actions, without being required to post a bond. None of the rights, powers or remedies conferred under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in addition to any other right, power or
remedy, whether conferred by this Agreement or now or hereafter available at law, in equity, by statute or otherwise. 

6.10    Governing Law. This Agreement shall be governed by, interpreted under, and construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be performed within the State of New York, without giving effect to any choice-of-law
provisions thereof that would compel the application of the substantive laws of any other jurisdiction. 

6.11    Waiver of Trial by Jury. Each party hereby irrevocably and unconditionally waives the right to a trial by
jury in any action, suit, counterclaim or other proceeding (whether based on contract, tort or otherwise) arising out of, connected with or relating to this Agreement, the transactions contemplated hereby, or the actions of the parties in the
negotiation, administration, performance or enforcement hereof.

rule promulgated thereafter by the Commission)), or (ii) Cowen and Chardan are permitted to sell the Registrable Securities under Rule 144 (or any similar provision) under the Securities Act without limitation on the amount of securities sold
or the manner of sale. The provisions of Section 3.5 shall survive any termination.
