issue and sell to the Investor up to $25,000,000 (the “Total Commitment”) worth of duly authorized, validly issued, fully paid and non-assessable shares of Common Stock (subject in all cases to the Exchange Cap (except to the extent
the Exchange Cap shall be inapplicable as expressly provided in Sections 2.12 and 2.13), the “Aggregate Limit”), by (i) the delivery to the Investor of not more than 24 separate Fixed Request Notices (unless the Investor and
the Company mutually agree that a different number of Fixed Request Notices may be delivered) as provided in Article II hereof and (ii) the exercise by the Investor of Optional Amounts, which the Company may in its discretion grant to the
Investor and which may be exercised by the Investor, in whole or in part, as provided in Article II hereof. The aggregate of all Fixed Request Amounts and Optional Amount Dollar Amounts shall not exceed the Aggregate Limit.

New York 10166, at 5:00 p.m., New York time, on the Effective Date. In consideration of and in express reliance upon the representations, warranties and covenants, and otherwise upon the terms
and subject to the conditions, of this Agreement, from and after the Effective Date and during the Investment Period (i) the Company shall issue and sell to the Investor, and the Investor agrees to purchase from the Company, the Shares in
respect of each Fixed Request and (ii) the Investor may in its discretion elect to purchase Shares in respect of each Optional Amount. The issuance and sale of Shares to the Investor pursuant to any Fixed Request or Optional Amount shall occur

 Section 1.3
Reservation of Common Stock. The Company has or will have duly authorized and reserved for issuance, and covenants to continue to so reserve once reserved for issuance, free of all preemptive and other similar rights, at all times during

Supplement prior to filing the Current Report and Initial Prospectus Supplement with the Commission, shall give due consideration to all such comments and shall not file the Current Report or Initial Prospectus Supplement to the extent the Investor
reasonably objects to the form or content thereof (provided, however, that the failure of the Investor to make such objection shall not relieve the Company of any obligation or liability under this Agreement or affect the
Investor’s right to rely on the representations and warranties made by the Company in this Agreement). If the transactions contemplated by any Fixed Request are material to the Company (individually or collectively with other prior Fixed
Requests, the consummation of which have not previously been reported in any Prospectus Supplement filed with the Commission under Rule 424(b) under the Securities Act or in any report, statement or other document filed by the Company with the

 2

information described in the immediately preceding sentence relating to all Fixed Request(s) consummated during the relevant fiscal quarter. 
 ARTICLE II 
 FIXED REQUEST TERMS; OPTIONAL AMOUNT 

Subject to the satisfaction or (to the extent permitted by applicable law) waiver of the conditions set forth in this Agreement, the
parties agree (unless otherwise mutually agreed upon by the parties in writing) as follows: 
 Section 2.1 Fixed
Request Notice. The Company may, from time to time in its sole discretion, no later than 9:30 a.m. (New York time) on the first Trading Day of the Pricing Period, provide to the Investor a Fixed Request notice, substantially in the form
attached hereto as Exhibit A (the “Fixed Request Notice”), which Fixed Request Notice shall become effective at 9:30 a.m. (New York time) on the first Trading Day of the Pricing Period specified in the Fixed Request Notice;
provided, however, that if the Company delivers the Fixed Request Notice to the Investor later than 9:30 a.m. (New York time) on a Trading Day, then the first Trading Day of such Pricing Period shall not be the Trading Day on which the
Investor received such Fixed Request Notice, but rather shall be the next Trading Day (unless a subsequent Trading Day is therein specified). The Company shall provide the Investor with at least one Trading Day’s prior notice of its intent to
deliver a Fixed Request Notice to the Investor. The Fixed Request Notice shall specify the Fixed Amount Requested, establish the Threshold Price for such Fixed Request, designate the first and last Trading Day of the Pricing Period and specify the
Optional Amount, if any, that the Company elects to grant to the Investor during the Pricing Period and the applicable Threshold Price for such Optional Amount (the “Optional Amount Threshold Price”). The Threshold Price and the
Optional Amount Threshold Price established by the Company in a Fixed Request Notice may be the same or different, in the Company’s sole discretion. Upon the terms and subject to the conditions of this Agreement, the Investor is obligated to
accept each Fixed Request Notice prepared and delivered in accordance with the provisions of this Agreement. 

Section 2.2 Fixed Requests. From time to time during the Investment Period, the Company may, in its sole discretion,
deliver to the Investor a Fixed Request Notice for a specified Fixed Amount Requested, and the applicable discount price (the “Discount Price”) shall be determined, in accordance with the price and share amount parameters as set
forth below or such other parameters mutually agreed upon by the Investor and the Company, and upon the terms and subject to the conditions of this Agreement, the Investor shall purchase from the


  
 3 








 
Company the Shares subject to such Fixed Request Notice at the Discount Price; provided, however, that (i) if an ex-dividend date is established by the Trading Market in
respect of the Common Stock on or between the first Trading Day of the applicable Pricing Period and the applicable Settlement Date, the Discount Price shall be reduced by the per share dividend amount and (ii) unless the parties otherwise
mutually agree, the Company may not deliver any single Fixed Request Notice for a Fixed Amount Requested in excess of the lesser of (a) the amount in the applicable Fixed Amount Requested column below and (b) 2.5% of the Market
Capitalization:

	  	Not to exceed $5,500,000	  	96.30% of the VWAP
			
	 Equal to or greater than $9.00 and less than $10.00

	 Equal to or greater than $6.00 and less than $7.00
	  	Not to exceed $3,500,000	  	95.50% of the VWAP
			
	 Equal to or greater than $5.00 and less than $6.00
	  	Not to exceed $3,000,000	  	95.30% of the VWAP
			
	 Equal to or greater than $4.00 and less than $5.00
	  	Not to exceed $2,500,000	  	95.10% of the VWAP

	 Equal to or greater than $1.00 and less than $3.00
	  	Not to exceed $1,000,000	  	94.70% of the VWAP

 Anything to the contrary in this Agreement notwithstanding, unless otherwise mutually agreed upon by the
Investor and the Company, at no time shall the Investor be required to purchase more than $10,000,000 worth of Common Stock in respect of any Pricing Period (not including Common Stock subject to any Optional Amount). The date on which the Company
delivers any Fixed Request Notice in accordance with this Section 2.2 hereinafter shall be referred to as a “Fixed Request Exercise Date”. 
 Section 2.3 Share Calculation. With respect to each Trading Day during the applicable Pricing Period for which the VWAP equals or exceeds the Threshold Price, the number of Shares to be
issued by the Company to the Investor pursuant to a Fixed Request shall equal the quotient (calculated for each Trading Day during the applicable Pricing Period for which the VWAP equals or exceeds the Threshold Price) determined pursuant to the
following equation (rounded to the nearest whole Share): 

  
 4 








 N = (A x B)/C, where: 
 N = the number of Shares to be issued by the Company to the Investor in respect of a Trading Day during the applicable Pricing Period for which the VWAP equals or exceeds the Threshold Price, 

A = 0.10 (the “Multiplier”), provided, however, that if the Company and the Investor mutually agree prior to the
commencement of a Pricing Period that the number of consecutive Trading Days constituting a Pricing Period shall be less than 10, then the Multiplier correspondingly shall be increased to equal the decimal equivalent (in 10-millionths) of a
fraction, the numerator of which is one and the denominator of which equals the number of Trading Days in the reduced Pricing Period (it being hereby acknowledged and agreed that this proviso shall not apply to any unilateral determination by the
Company to reduce a Pricing Period, but rather, in the event of such unilateral determination, Section 2.8 hereof shall apply), 
 B = the
total Fixed Amount Requested, and 
 C = the applicable Discount Price for such Trading Day. 

Section 2.4 Limitation of Fixed Requests. The Company shall not make more than one Fixed Request in each Pricing
Period. Not less than five Trading Days shall elapse between the end of one Pricing Period and the commencement of any other Pricing Period during the Investment Period. There shall be permitted a maximum of 24 Fixed Requests during the Investment
Period. Each Fixed Request automatically shall expire immediately following the last Trading Day of each Pricing Period. 

Section 2.5 Reduction of Commitment. On the Settlement Date with respect to a Pricing Period, the Investor’s
Total Commitment under this Agreement automatically (and without the need for any amendment to this Agreement) shall be reduced, on a dollar-for-dollar basis, by the total amount of the Fixed Request Amount and the Optional Amount Dollar Amount, if
any, for such Pricing Period paid to the Company at such Settlement Date. 
 Section 2.6 Below Threshold
Price. If the VWAP on any Trading Day in a Pricing Period is lower than the Threshold Price, then for each such Trading Day the Fixed Amount Requested shall be reduced, on a dollar-for-dollar basis, by an amount equal to the product of
(x) the Multiplier and (y) the total Fixed Amount Requested, and no Shares shall be purchased or sold with respect to such Trading Day, except as provided below. If trading in the Common Stock on NASDAQ (or any other Trading Market on
which the Common Stock is then listed or quoted) is suspended for any reason for more than three hours on any Trading Day, the Investor may at its option deem the price of the Common Stock to be lower than the Threshold Price for such Trading Day
and, for each such Trading Day, the total amount of the Fixed Amount Requested shall be reduced as provided in the immediately preceding sentence, and no Shares shall be purchased or sold with respect to such Trading Day, except as provided below.
For each Trading Day during a Pricing Period on which the VWAP is lower (or is deemed to be lower as provided in the immediately preceding sentence) than the Threshold Price, the Investor may in its sole discretion elect to purchase such U.S. dollar
amount of Shares equal to the amount by which the Fixed Amount Requested has been reduced in accordance with this Section 2.6, at the 

  
 5 








 
Threshold Price multiplied by the applicable percentage set forth in the column entitled “Discount Price” for the row corresponding to the applicable Threshold Price in
Section 2.2. The Investor shall inform the Company via facsimile transmission not later than 8:00 p.m. (New York time) on the last Trading Day of such Pricing Period as to the number of Shares, if any, the Investor elects to purchase as
provided in this Section 2.6. 
 Section 2.7 Settlement. The payment for, against simultaneous delivery
of, Shares in respect of each Fixed Request shall be settled on the second Trading Day next following the last Trading Day of each Pricing Period, or on such earlier date as the parties may mutually agree (the “Settlement Date”). On
each Settlement Date, the Company shall, or shall cause its transfer agent to, electronically transfer the Shares purchased by the Investor by crediting the Investor’s or its designees’ account at DTC through its Deposit/Withdrawal at
Custodian (DWAC) system, which Shares shall be freely tradable and transferable and without restriction on resale, against simultaneous payment therefor to the Company’s designated account by wire transfer of immediately available funds;
provided that if the Shares are received by the Investor later than 1:00 p.m. (New York time), payment therefor shall be made with next day funds. As set forth in Section 9.1(ii), a failure by the Company to deliver such Shares shall
result in the payment of partial damages by the Company to the Investor. 
 Section 2.8 Reduction of Pricing
Period. If during a Pricing Period the Company elects to reduce the number of Trading Days in such Pricing Period (and thereby amend its previously delivered Fixed Request Notice), the Company shall so notify the Investor before 9:00 a.m.
(New York time) on any Trading Day during a Pricing Period (a “Reduction Notice”) and the last Trading Day of such Pricing Period shall be the Trading Day immediately preceding the Trading Day on which the Investor received such
Reduction Notice; provided, however, that if the Company delivers the Reduction Notice later than 9:00 a.m. (New York time) on a Trading Day during a Pricing Period, then the last Trading Day of such Pricing Period instead shall be the
Trading Day on which the Investor received such Reduction Notice. 
 Upon receipt of a Reduction Notice, the Investor
(i) shall purchase the Shares in respect of each Trading Day in such reduced Pricing Period for which the VWAP equals or exceeds the Threshold Price in accordance with Section 2.3 hereof; (ii) may elect to purchase the Shares in
respect of any Trading Day in such reduced Pricing Period for which the VWAP is (or is deemed to be) lower than the Threshold Price in accordance with Section 2.6 hereof; and (iii) may elect to exercise all or any portion of an Optional
Amount on any Trading Day during such reduced Pricing Period in accordance with Sections 2.10 and 2.11 hereof. 
 In addition,
upon receipt of a Reduction Notice, the Investor may elect to purchase, by providing written notice to the Company not later than 10:00 a.m. (New York time) on the first Trading Day following the last Trading Day of the reduced Pricing Period, such
U.S. dollar amount of additional Shares equal to the product determined pursuant to the following equation: 
 D = (A/B) x (B – C), where:

 D = the U.S. dollar amount of additional Shares to be purchased, 
 A = the Fixed Amount Requested, 

  
 6 








 B = 10 or, for purposes of this Section 2.8, such lesser number of Trading Days as the parties may
mutually agree to, and 
 C = the number of Trading Days in the reduced Pricing Period, 

at a per Share price equal to the average per share price to be paid for Shares to be purchased during such reduced Pricing Period pursuant to clauses
(i) and (ii) (as applicable) of the immediately preceding paragraph. 
 The Investor may also elect to exercise any
portion of the applicable Optional Amount which was unexercised during the reduced Pricing Period by issuing an Optional Amount Notice to the Company not later than 10:00 a.m. (New York time) on the first Trading Day next following the last Trading
Day of the reduced Pricing Period. The number of Shares to be issued upon exercise of such Optional Amount shall be calculated pursuant to the equation set forth in Section 2.10 hereof, except that “C” shall equal the greater of
(i) the VWAP for the Common Stock on the last Trading Day of the reduced Pricing Period or (ii) the Optional Amount Threshold Price. 
 The payment for, against simultaneous delivery of, Shares to be purchased and sold in accordance with this Section 2.8 shall be settled on the second Trading Day next following the Trading Day on
which the Investor receives a Reduction Notice. 
 Section 2.9 Optional Amount. With respect to any Pricing
Period, the Company may in its sole discretion grant to the Investor the right to exercise, from time to time during the Pricing Period (but not more than once on any Trading Day), all or any portion of an Optional Amount. The maximum Optional
Amount Dollar Amount and the Optional Amount Threshold Price shall be set forth in the Fixed Request Notice. If an ex-dividend date is established by the Trading Market in respect of the Common Stock on or between the first Trading Day of the
applicable Pricing Period and the applicable Settlement Date, the applicable exercise price in respect of the Optional Amount shall be reduced by the per share dividend amount. Each daily Optional Amount exercise shall be aggregated during the
Pricing Period and settled on the next Settlement Date. The Optional Amount Threshold Price designated by the Company in its Fixed Request Notice shall apply to each Optional Amount exercised during the applicable Pricing Period. 

Section 2.10 Calculation of Optional Amount Shares. The number of shares of Common Stock to be issued in connection
with the exercise of an Optional Amount shall be the quotient determined pursuant to the following equation (rounded to the nearest whole Share): 
 O = A/(B x C), where: 
 O = the number of shares of Common Stock to be issued in connection with
such Optional Amount exercise, 
 A = the Optional Amount Dollar Amount with respect to which the Investor has delivered an Optional Amount
Notice, 

  
 7 








 B = the applicable percentage set forth in the column entitled “Discount Price” for the row
corresponding to the applicable Threshold Price in Section 2.2 (with the Optional Amount Threshold Price serving as the Threshold Price for such purposes), and 
 C = the greater of (i) the VWAP for the Common Stock on the day the Investor delivers the Optional Amount Notice or (ii) the Optional Amount Threshold Price. 

Section 2.11 Exercise of Optional Amount. If granted by the Company to the Investor with respect to a Pricing Period,
all or any portion of the Optional Amount may be exercised by the Investor on any Trading Day during the Pricing Period, subject to the limitations set forth in Section 2.9. As a condition to each exercise of an Optional Amount pursuant to this
Section 2.11, the Investor shall issue an Optional Amount Notice to the Company no later than 8:00 p.m. (New York time) on the day of such Optional Amount exercise. If the Investor does not exercise an Optional Amount in full by 8:00 p.m. (New
York time) on the last Trading Day of the applicable Pricing Period, such unexercised portion of the Investor’s Optional Amount with respect to that Pricing Period automatically shall lapse and terminate. 

Section 2.12 Exchange Cap; Single Fixed Request Limit. Notwithstanding anything to the contrary contained in this
Agreement, subject to Section 2.13 below, (i) the Company shall not issue or sell any shares of Common Stock pursuant to this Agreement (including, without limitation, as partial damages pursuant to Section 9.1(ii)), and the Investor
shall not purchase or acquire any shares of Common Stock pursuant to this Agreement, to the extent that after giving effect thereto, the aggregate number of shares of Common Stock that would be issued pursuant to this Agreement would exceed the
Exchange Cap, and (ii) the Company shall not issue or sell any shares of Common Stock pursuant to any single Fixed Request or Optional Amount (including, without limitation, as partial damages pursuant to Section 9.1(ii)), and the Investor
shall not purchase or acquire any shares of Common Stock pursuant to any single Fixed Request or Optional Amount, to the extent that after giving effect thereto, the aggregate number of shares of Common Stock that would be issued pursuant to such
Fixed Request and Optional Amount would exceed the Single Fixed Request Limit (taking into account all shares of Common Stock issued or issuable pursuant to any transaction or series of transactions that may be aggregated with the transactions
contemplated by such Fixed Request and Optional Amount under applicable rules of NASDAQ or any other Trading Market on which the Common Stock may be listed or quoted), in each case, unless and until the stockholders of the Company have approved the
transactions contemplated by this Agreement in accordance with the applicable rules and regulations of NASDAQ, any other Trading Market on which the Common Stock may be listed or quoted, and the Charter and Bylaws of the Company. For the avoidance
of doubt, the Company may, but shall be under no obligation to, solicit stockholder approval of the transactions contemplated by this Agreement; provided, that if stockholder approval of the transactions contemplated hereby is not obtained,
each of the Exchange Cap and the Single Fixed Request Limit shall be applicable for all purposes of this Agreement and the transactions contemplated hereby at all times during the term of this Agreement (except as set forth in Section 2.13
below). If the Company issues a Fixed Request Notice or Optional Amount that otherwise would permit the Investor to purchase shares of Common Stock which would cause the aggregate purchases by the Investor under this Agreement to exceed the
Aggregate Limit, such Fixed Request Notice or Optional Amount shall be void ab initio to the extent of the amount by which the dollar value of shares or number of shares, as the case may be, of Common Stock


  
 8 








 
otherwise issuable pursuant to such Fixed Request Notice or Optional Amount together with the dollar value of shares or number of shares, as the case may be, of all other Common Stock purchased
by the Investor pursuant to this Agreement, or issued as partial damages pursuant to Section 9.1(ii), would exceed the Aggregate Limit. If the Company issues a Fixed Request Notice or Optional Amount that otherwise would permit the Investor to
purchase shares of Common Stock which, when aggregated with all other shares of Common Stock issued or sold pursuant to any transaction or series of transactions that may be aggregated with the transactions contemplated by such Fixed Request Notice
and Optional Amount under applicable rules of NASDAQ or any other Trading Market on which the Common Stock may be listed or quoted, would exceed the Single Fixed Request Limit, such Fixed Request Notice or Optional Amount, as the case may be, shall
be void ab initio to the extent of the amount by which the number of shares of Common Stock otherwise issuable pursuant to such Fixed Request Notice or Optional Amount, as the case may be, together with all shares of Common Stock issued
pursuant to all such other aggregated transactions, would exceed the Single Fixed Request Limit. The Company hereby represents, warrants and covenants that it (i) has not effected any transaction or series of transactions, (ii) is not a
party to any pending transaction or series of transactions or (iii) shall not enter into any contract, agreement, agreement-in-principle, arrangement or understanding with respect to, or shall effect, any Other Financing which, in any of such
cases, may be aggregated with the transactions contemplated by this Agreement for purposes of determining whether approval of the Company’s stockholders is required under applicable rules of NASDAQ or any other Trading Market on which the
Common Stock may be listed or quoted; provided, however, that the Company shall be permitted to take any action referred to in clause (iii) of this sentence if (a) the Company has timely provided the Investor with an
Integration Notice as provided in Section 5.6(ii) hereof and (b) unless the Investor has previously terminated this Agreement pursuant to Section 7.2, the Company obtains any requisite stockholder approval which may be required for
the Company to consummate such Other Financing described in such Integration Notice. 
 At the Company’s sole discretion,
and effective automatically upon delivery of notice thereof by the Company to the Investor, this Agreement may be amended by the Company from time to time to reduce the Total Commitment by a specified dollar amount as shall be determined by the
Company in its sole discretion; provided, however, that any such amendment of this Agreement (and any such purported amendment) shall be void and of no force and effect if the effect thereof would restrict, materially delay, conflict
with or impair the ability or right of the Company to perform its obligations under this Agreement, including, without limitation, the obligation of the Company to deliver the Shares to the Investor in respect of a previously delivered Fixed Request
Notice or Optional Amount on the applicable Settlement Date. In the event the Company shall have elected to reduce the Total Commitment as provided in the immediately preceding sentence, at the Company’s sole discretion, and effective
automatically upon delivery of notice thereof by the Company to the Investor, the Company may subsequently amend this Agreement to increase the Total Commitment up to $25,000,000; provided, however, that in no event shall the Company
be entitled to issue Fixed Request Notices and grant Optional Amounts during the remainder of the Investment Period for an aggregate amount greater than the amount obtained by subtracting (x) the aggregate of all Fixed Request Amounts and
Optional Amount Dollar Amounts (including any amounts paid as partial damages pursuant to Section 9.1(ii) hereunder) covered by all Fixed Request Notices and Optional Amounts theretofore issued or granted by the Company in respect of which a
settlement has occurred pursuant to 

  
 9 








 
Section 2.7 from (y) $25,000,000, subject, in all cases, to the Exchange Cap (except to the extent the Exchange Cap shall be inapplicable as expressly provided in Sections 2.12 and
2.13). 
 Section 2.13 Trading Market Regulation. Notwithstanding anything in this Agreement to the contrary,
neither the Exchange Cap nor the Single Fixed Request Limit shall be applicable for any purposes of this Agreement or the transactions contemplated hereby, solely to the extent (and only for so long as) the Average Discount Price shall equal or
exceed the Base Price (it being hereby acknowledged and agreed that each of the Exchange Cap and the Single Fixed Request Limit shall be applicable for all purposes of this Agreement and the transactions contemplated hereby at all other times during
the term of this Agreement); provided, however, that the Company shall not issue any shares of Common Stock under this Agreement if such issuance would otherwise breach the Company’s obligations under the rules and regulations of
NASDAQ or any other Trading Market on which the Common Stock may be listed or quoted. “Base Price” shall mean a price per Share equal to $5.48, representing the consolidated closing bid price of the Common Stock as reported on
NASDAQ on the Effective Date, subject to (a) upward adjustment (by such amount to be mutually agreed by the Company and the Investor consistent with the rules and regulations of NASDAQ or any other Trading Market on which the Common Stock may
be listed or quoted) in the event any shares of Common Stock are issued by the Company as partial damages pursuant to Section 9.1(ii) and (b) adjustment for any stock splits, stock combinations, stock dividends, recapitalizations and other
similar transactions that occur on or after the date of this Agreement. The Company hereby represents and warrants to the Investor that the book value per share of Common Stock on the Effective Date is less than the Base Price. “Average
Discount Price” shall mean a price per Share (rounded to the nearest tenth of a cent) equal to the quotient obtained by dividing (i) the total aggregate gross purchase price paid by the Investor for all Shares purchased pursuant to all
Fixed Requests and Optional Amounts under this Agreement, by (ii) the total aggregate number of Shares issued pursuant to all Fixed Requests and Optional Amounts under this Agreement. The provisions of this Section 2.13 shall be
implemented in a manner otherwise than in strict conformity with the terms of this Section 2.13, only if necessary to ensure compliance with the rules and regulations of NASDAQ or any other Trading Market on which the Common Stock may be listed
or quoted. 
 Section 2.14 Blackout Periods. The Company shall advise the Investor in writing of any changes
to its policy on insider trading. Notwithstanding any other provision of this Agreement, the Company shall not deliver any Fixed Request Notice or grant any Optional Amount or otherwise offer, sell or deliver Shares to the Investor, and the Investor
shall not be obligated to purchase any Shares pursuant to this Agreement, (i) during any period in which the Company is, or may be deemed to be, in possession of material non-public information, (ii) during any period (other than the
period referred to in clause (iii) of this Section 2.14) in which the Company’s insider trading policy, as it exists from time to time, would prohibit purchases or sales of Common Stock by its officers or directors (each such period,
a “Blackout Period”), except with respect to this clause (ii) as expressly provided in the immediately following sentence, or (iii) except as expressly provided in this Section 2.14, at any time from and 

  
 10 









 
including the date (each, an “Announcement Date”) on which the Company shall issue a press release containing, or shall otherwise publicly announce, its earnings, revenues or
other results of operations (each, an “Earnings Announcement”) through and including the time that is 24 hours after the time that the Company files (a “Filing Time”) a Quarterly Report on Form 10-Q or an Annual
Report on Form 10-K that includes consolidated financial statements as of and for the same period or periods, as the case may be, covered by such Earnings Announcement. If the Company wishes to deliver any Fixed Request Notice or grant any Optional
Amount or otherwise offer, sell or deliver Shares to the Investor during any Blackout Period, the Company shall, as conditions thereto, (A) provide the Investor with the compliance certificate substantially in the form attached hereto as
Exhibit D, dated the date of such Fixed Request Notice or Optional Amount grant, as applicable, which certificate shall be deemed to remain in effect during the applicable Pricing Period through and including the applicable Settlement Date,
and the “bring down” opinions in the form mutually agreed to by the parties hereto, dated the date of such Fixed Request Notice or Optional Amount grant, as applicable, and (B) afford the Investor the opportunity to conduct a due
diligence review in accordance with Section 5.4 hereof. If the Company wishes to deliver any Fixed Request Notice or grant any Optional Amount or otherwise offer, sell or deliver Shares to the Investor at any time during the period from and
including an Announcement Date through and including the time that is 24 hours after the corresponding Filing Time, the Company shall, as conditions thereto, (1) prepare and deliver to the Investor (with a copy to counsel to the Investor) a
report on Form 8-K which shall include substantially the same financial and related information as was set forth in the relevant Earnings Announcement (other than any earnings or other projections, similar forward-looking data and officers’
quotations) (each, an “Earnings 8-K”), in form and substance reasonably satisfactory to the Investor and its counsel, (2) provide the Investor with the compliance certificate substantially in the form attached hereto as
Exhibit D, dated the date of such Fixed Request Notice or Optional Amount grant, as applicable, which certificate shall be deemed to remain in effect during the applicable Pricing Period through and including the applicable Settlement Date,
and the “bring down” opinions in the form mutually agreed to by the parties hereto, dated the date of such Fixed Request Notice or Optional Amount grant, as applicable, (3) afford the Investor the opportunity to conduct a due
diligence review in accordance with Section 5.4 hereof and (4) file such Earnings 8-K with the Commission (so that it is deemed “filed” for purposes of Section 18 of the Exchange Act) on or prior to the date of such Fixed
Request Notice or Optional Amount grant, as applicable. The provisions of clause (iii) of this Section 2.14 shall not be applicable for the period from and after the time at which all of the conditions set forth in the immediately
preceding sentence shall have been satisfied (or, if later, the time that is 24 hours after the time that the relevant Earnings Announcement was first publicly released) through and including the time that is 24 hours after the Filing Time of the
relevant Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be. For purposes of clarity, the parties agree that the delivery of the compliance certificate and the “bring down” opinions pursuant to this
Section 2.14 shall not relieve the Company from any of its obligations under this Agreement with respect to the delivery of the compliance certificate called for by Section 6.3(v) and the “bring down” opinions called for by
Section 6.3(xii) on the applicable Settlement Date, which Sections shall have independent application.

with respect to the fairness and reasonableness of the terms of the transactions contemplated by this Agreement; provided, however, that the Investor shall have no responsibility for the compliance or non-compliance of any
Broker-Dealer with FINRA Rule 5110 and shall not be required to (x) disclose to FINRA or to any other governmental agency, person or entity any business, financial or other information that the Investor deems, in its sole


  
 26 









 
and absolute discretion, to be proprietary, confidential or otherwise sensitive information, (y) amend, modify or change any of the terms or conditions of this Agreement or
(z) otherwise take any other action, including, without limitation, modifying the Discount Price thresholds referred to in Section 2.2 or the amount of fees and commissions to be paid to the Broker-Dealer in connection with the
transactions contemplated by this Agreement, in each case, in such a manner that would, in the Investor’s sole and absolute discretion, render the terms and conditions of this Agreement or the transactions contemplated hereby to be no longer
advisable to the Investor. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not pay any fees to FWG in connection with any of the transactions contemplated by this Agreement, unless and until the parties hereto
and FWG shall have received written confirmation from FINRA to the effect that FINRA’s Corporate Financing Department has determined not to raise any objection with respect to the fairness and reasonableness of the terms of the transactions
contemplated by this Agreement.

necessary to cause the Common Stock to continue to be registered as a class of securities under Sections 12(b) or 12(g) of the Exchange Act, shall comply in all material respects with its reporting and filing obligations under the Exchange Act, and
shall not take any action or file any document (whether or not permitted by the Securities Act or the Exchange Act) to terminate or suspend such registration or to terminate or suspend its reporting and filing obligations under the Exchange Act or
Securities Act, except as permitted herein. Without limiting the generality of the foregoing, the Company shall file all reports, schedules, registrations, forms, statements, information and other documents required to be filed by the Company with
the Commission pursuant to the Exchange Act, including all material required to be filed pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, in each case within the time periods required by the Exchange Act (giving effect to
permissible extensions in accordance with Rule 12b-25 under the Exchange Act). The Company shall use its reasonable best efforts to continue the listing and trading of its Common Stock and the listing of the Shares purchased by the Investor
hereunder on the Trading Market, and shall comply with the Company’s reporting, filing and other obligations under the bylaws, listed securities maintenance standards and other rules and regulations of FINRA and the Trading Market. The Company
shall not take any action which could reasonably be expected to result in the delisting or suspension of the Common Stock on the Trading Market. 
 Section 5.3 Compliance with Laws. 
 (i) The Company shall
comply, (a) with all laws, rules, regulations, permits and orders applicable to the business and operations of the Company, except as would not have a Material Adverse Effect and (b) with all applicable provisions of the Securities Act,
the Exchange Act, the rules and regulations of the FINRA and the listing standards of the Trading Market. Without limiting the foregoing: (A) neither the Company nor any of its officers or directors (1) will take, directly or indirectly,
any action designed or intended to cause or to result in, or which would in the future reasonably be expected to cause or result in, the stabilization or manipulation of the price of any security of the Company, in each case to facilitate the sale
or resale of any of the Shares, or (2) sell, bid for, purchase, or pay any compensation for soliciting purchases of, any of the Shares, other than, in the case of clause (2), compensation paid to FWG in connection with the settlement of each
Fixed Request pursuant to this Agreement; and (B)

  
 27 









 
neither the Company, nor to the Knowledge of the Company, any of its respective directors, officers, agents, employees or any other Persons acting on its behalf shall, in connection with the
operation of the Company’s business, (a) use any corporate funds for unlawful contributions, payments, gifts or entertainment or to make any unlawful expenditures relating to political activity to government officials, candidates or
members of political parties or organizations, (b) pay, accept or receive any unlawful contributions, payments, expenditures or gifts, or (c) violate or operate in noncompliance with any export restrictions, anti-boycott regulations,

 (ii) The Investor shall comply with all laws, rules, regulations and orders applicable to the performance by it of its obligations under this Agreement and its investment in the Shares, except as would
not, individually or in the aggregate, prohibit or otherwise interfere with the ability of the Investor to enter into and perform its obligations under this Agreement in any material respect. Without limiting the foregoing, the Investor shall comply
with all applicable provisions of the Securities Act and the Exchange Act, including Regulation M thereunder, and any applicable securities laws of any non-U.S. jurisdictions. Neither the Investor nor any of its officers or directors will take,
directly or indirectly, any action designed or intended to cause or to result in, or which would in the future reasonably be expected to cause or result in, the stabilization or manipulation of the price of any security of the Company, in each case
to facilitate the sale or resale of any of the Shares. 
 Section 5.4 Due Diligence. Subject to the
requirements of Section 5.12 of this Agreement, from time to time from and after the period beginning with the third Trading Day immediately preceding each Fixed Request Exercise Date through and including the applicable Settlement Date, the
Company shall make available for inspection and review by the Investor, customary documentation allowing the Investor and/or its appointed counsel or advisors to conduct due diligence. 

Section 5.5 Limitations on Holdings and Issuances. Notwithstanding any other provision of this Agreement, the Company
shall not issue and the Investor shall not purchase any shares of Common Stock which, when aggregated with all other shares of Common Stock then beneficially owned (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3
promulgated thereunder) by the Investor and its Affiliates, would result in the beneficial ownership by the Investor of more than 9.9% of the then issued and outstanding shares of Common Stock. Upon the written or oral request of the Investor, the
Company shall promptly (but not later than the next Trading Day) confirm orally or in writing to the Investor the number of shares of Common Stock then outstanding. The Investor and the Company shall each cooperate in good faith in the
determinations required hereby and the application hereof. The Investor’s written certification to the Company of the applicability of this beneficial ownership limitation, and the resulting effect thereof hereunder at any time, shall be
conclusive with respect to the applicability thereof and such result absent manifest error. 
 Section 5.6 Other
Agreements and Other Financings. 
 (i) The Company shall not enter into, announce or recommend to its stockholders any
agreement, plan, arrangement or transaction in or of which the terms thereof 

  
 28 









 
would restrict, materially delay, conflict with or impair the ability or right of the Company to perform its obligations under this Agreement, including, without limitation, the obligation of the
Company to deliver the Shares to the Investor in respect of a previously provided Fixed Request Notice or Optional Amount on the applicable Settlement Date. 
 (ii) If the Company enters into any agreement, plan, arrangement or transaction with a third party or seeks to utilize any existing agreement, plan or arrangement with a third party, in each case the
principal purpose of which is to implement, effect or consummate, at any time during the period beginning on the first Trading Day of any Pricing Period and ending on the second Trading Day next following the applicable Settlement Date (the
“Reference Period”), an Other Financing that does not constitute an Acceptable Financing, the Company shall provide prompt notice thereof (an “Other Financing Notice”) to the Investor; provided,
however, that such Other Financing Notice must be received by the Investor not later than the earlier of (a) 48 hours after the Company’s execution of any agreement, plan, arrangement or transaction relating to such Other
Financing (or, with respect to any existing agreement, plan or arrangement, 48 hours after the Company has determined to utilize any such existing agreement, plan or arrangement to implement, effect or consummate such Other Financing) and
(b) the second Trading Day immediately preceding the applicable Settlement Date with respect to the applicable Fixed Request Notice; provided, further, that the Company shall notify the Investor within 24 hours (an
“Integration Notice”) if it enters into any agreement, plan, arrangement or transaction with a third party, the principal purpose of which is to obtain at any time during the Investment Period an Other Financing that may be
aggregated with the transactions contemplated by this Agreement for purposes of determining whether approval of the Company’s stockholders is required under any bylaw, listed securities maintenance standards or other rules of the Trading Market
and, if required under applicable law, including, without limitation, Regulation FD promulgated by the Commission, or under the applicable rules and regulations of the Trading Market, the Company shall publicly disclose such information in
accordance with Regulation FD and the applicable rules and regulations of the Trading Market. For purposes of this Section 5.6(ii), any press release issued by, or Commission Document filed by, the Company shall constitute sufficient notice,
provided that it is issued or filed, as the case may be, within the time requirements set forth in the first sentence of this Section 5.6(ii) for an Other Financing Notice or an Integration Notice, as applicable. With respect to any Pricing
Period for which the Company is required to provide an Other Financing Notice pursuant to the first sentence (including the provisos thereto) of this Section 5.6(ii), the Investor shall have the option to purchase the Shares subject to the
Fixed Request at (i) the price therefor in accordance with the terms of this Agreement or (ii) the third party’s per share purchase price in connection with the Other Financing, net of such third party’s discounts, Warrant Value
and fees. An “Other Financing” shall mean (w) the issuance for cash of Common Stock for a purchase price less than, or the issuance for cash of securities convertible into or exchangeable for Common Stock at an exercise or
conversion price (as the case may be) less than, the then Current Market Price of the Common Stock (including, without limitation, pursuant to any “equity line” or other financing that is substantially similar to the financing provided for
under this Agreement, or pursuant to any other transaction in which the purchase, conversion or exchange price for such Common Stock is determined using a floating discount or other post-issuance adjustable discount to the then Current Market Price
(any such transaction, a “Similar Financing”)), in each case, after all fees, discounts, Warrant Value and commissions associated with the transaction (a “Below Market Offering”); (x) an
“at-the-market” offering for cash of Common Stock or securities convertible 

  
 29 









 
into or exchangeable for Common Stock pursuant to Rule 415(a)(4) under the Securities Act (an “ATM”); (y) the implementation by the Company of any mechanism in respect of
any securities convertible into or exchangeable for Common Stock for the reset of the purchase price of the Common Stock to below the then Current Market Price of the Common Stock (including, without limitation, any antidilution or similar
adjustment provisions in respect of any Company securities, but specifically excluding customary adjustments for stock splits, stock dividends, stock combinations and similar events) (a “Price Reset Provision”); or (z) the
issuance of options, warrants or similar rights of subscription, in the case of each of clause (w) and (z) not constituting an Acceptable Financing (it being acknowledged and agreed that notwithstanding anything herein to the contrary, any
Similar Financing, ATM or Price Reset Provision shall not constitute an Acceptable Financing). “Acceptable Financing” shall mean the issuance by the Company of: (1) debt securities or any class or series of preferred stock of
the Company, in each case that are not convertible into or exchangeable for Common Stock or securities convertible into or exchangeable for Common Stock; (2) shares of Common Stock or securities convertible into or exchangeable for Common Stock
(including, without limitation, convertible debt securities) other than in connection with a Below Market Offering or an ATM, and the issuance of shares of Common Stock upon conversion, exercise or exchange thereof; (3) shares of Common Stock
or securities convertible into or exchangeable for Common Stock (including, without limitation, convertible debt securities) in connection with an underwritten public offering (or offering under Rule 144A under the Securities Act) of securities of
the Company or a registered direct public offering of securities of the Company, in each case where the price per share of such Common Stock (or the conversion or exercise price of such securities, as applicable) is fixed concurrently with the
execution of definitive documentation relating to such offering, and the issuance of shares of Common Stock upon the conversion, exercise or exchange thereof; (4) shares of Common Stock or securities convertible into or exchangeable for Common
Stock in connection with awards under the Company’s benefit and equity plans and arrangements or shareholder rights plan (as applicable) and the issuance of shares of Common Stock upon the conversion, exercise or exchange thereof;
(5) shares of Common Stock issuable upon the conversion or exchange of equity awards or convertible, exercisable or exchangeable securities (including, without limitation, convertible debt securities) outstanding as of the Effective Date;
(6) shares of Common Stock in connection with stock splits, stock dividends, stock combinations, recapitalizations, reclassifications and similar events; (7) shares of Common Stock or securities convertible into or exchangeable for Common
Stock (including, without limitation, convertible debt securities) issued in connection with the acquisition, license or sale of one or more other companies, equipment, technologies, other assets or lines of business, and the issuance of shares of
Common Stock upon the conversion, exercise or exchange thereof; (8) shares of Common Stock or securities convertible into or exchangeable for Common Stock (including, without limitation, convertible debt securities) or similar rights to
subscribe for the purchase of shares of Common Stock in connection with technology sharing, collaboration, partnering, licensing, research and joint development agreements (or amendments thereto) with third parties, and the issuance of shares of
Common Stock upon the conversion, exercise or exchange thereof; (9) shares of Common Stock or securities convertible into or exchangeable for Common Stock to employees, consultants and/or advisors as consideration for services rendered or to be
rendered, and the issuance of shares of Common Stock upon conversion, exercise or exchange thereof; and (10) shares of Common Stock or securities convertible into or exchangeable for Common Stock issued in connection with capital or equipment

 30 









 
and/or real property lease arrangements, and the issuance of shares of Common Stock upon the conversion, exercise or exchange thereof. 

Section 5.7 Stop Orders. The Company shall advise the Investor promptly (but in no event later than 24 hours) and
shall confirm such advice in writing: (i) of the Company’s receipt of notice of any request by the Commission for amendment of or a supplement to the Registration Statement, the Prospectus, any Permitted Free Writing Prospectus or for any
additional information; (ii) of the Company’s receipt of notice of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or prohibiting or suspending the use of the Prospectus or any
Prospectus Supplement, or of the suspension of qualification of the Shares for offering or sale in any jurisdiction, or the initiation or contemplated initiation of any proceeding for such purpose; and (iii) of the Company becoming aware of the
happening of any event, which makes any statement of a material fact made in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus untrue or which requires the making of any additions to or changes to the statements
then made in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus in order to state a material fact required by the Securities Act to be stated therein or necessary in order to make the statements then made therein (in
the case of the Prospectus, in light of the circumstances under which they were made) not misleading, or of the necessity to amend the Registration Statement or supplement the Prospectus or any Permitted Free Writing Prospectus to comply with the
Securities Act or any other law. The Company shall not be required to disclose to the Investor the substance or specific reasons of any of the events set forth in clauses (i) through (iii) of the immediately preceding sentence, but rather,
shall only be required to disclose that the event has occurred. The Company shall not issue any Fixed Request during the continuation of any of the foregoing events. If at any time the Commission shall issue any stop order suspending the
effectiveness of the Registration Statement or prohibiting or suspending the use of the Prospectus or any Prospectus Supplement, the Company shall use reasonable best efforts to obtain the withdrawal of such order at the earliest possible time. The
Company shall also advise the Investor promptly (but in no event later than 24 hours) and shall confirm such advice in writing of the Company becoming aware of the happening of any event, which makes any statement made in the FINRA Filing untrue or
which requires the making of any additions to or changes to the statements then made in the FINRA Filing in order to comply with FINRA Rule 5110. 
 Section 5.8 Amendments to the Registration Statement; Prospectus Supplements; Free Writing Prospectuses. 
 (i) Except as provided in this Agreement and other than periodic and current reports required to be filed pursuant to the Exchange Act, the Company shall not file with the Commission any amendment to the
Registration Statement that relates to the Investor, this Agreement or the transactions contemplated hereby or file with the Commission any Prospectus Supplement that relates to the Investor, this Agreement or the transactions contemplated hereby
with respect to which (a) the Investor shall not previously have been advised, (b) the Company shall not have given the Investor and its counsel a reasonable opportunity to comment on a draft thereof prior to filing with the Commission,
(c) the Company shall not have given due consideration to any comments thereon received from the Investor or its counsel prior to filing with the Commission, or (d) the Investor shall reasonably object after being so advised or after


  
 31 









 
having completed its review (provided, however, that the failure of the Investor to make such objection shall not relieve the Company of any obligation or liability under
this Agreement or affect the Investor’s right to rely on the representations and warranties made by the Company in this Agreement), unless the Company reasonably has determined that it is necessary to amend the Registration Statement or make
any supplement to the Prospectus to comply with the Securities Act or any other applicable law or regulation, in which case the Company shall promptly (but in no event later than 24 hours) so inform the Investor, the Investor shall be provided with
a reasonable opportunity to review and comment upon any disclosure relating to the Investor and the Company shall expeditiously furnish to the Investor an electronic copy thereof (it being acknowledged and agreed that the provisions of
Section 1.4, and not this Section 5.8, shall apply with respect to the Initial Prospectus Supplement). In addition, for so long as, in the reasonable opinion of counsel for the Investor, the Prospectus (or in lieu thereof, the notice
referred to in Rule 173(a) under the Securities Act) is required to be delivered in connection with any acquisition or sale of Shares by the Investor, the Company shall not file any (1) Prospectus Supplement with respect to the Shares, without
delivering or making available a copy of such Prospectus Supplement (in the form filed with the Commission), together with the Base Prospectus, to the Investor promptly after the filing thereof with the Commission, or (2) any amendment to the
Registration Statement, without promptly delivering or making available a copy of such amendment to the Registration Statement (in the form filed with the Commission) to the Investor promptly after the filing thereof with the Commission, in each
case via e-mail in “.pdf” format to an e-mail account designated by the Investor. 
 (ii) The Company has not made,
and agrees that unless it obtains the prior written consent of the Investor it will not make, an offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus
required to be filed by the Company or the Investor with the Commission or retained by the Company or the Investor under Rule 433 under the Securities Act. The Investor has not made, and agrees that unless it obtains the prior written consent of the
Company it will not make, an offer relating to the Shares that would constitute a Free Writing Prospectus required to be filed by the Company or the Investor with the Commission or retained by the Company or the Investor under Rule 433 under the
Securities Act. Any such Issuer Free Writing Prospectus or other Free Writing Prospectus consented to by the Investor or the Company is referred to in this Agreement as a “Permitted Free Writing Prospectus.” The Company agrees that
(x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433
under the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. 
 Section 5.9 Prospectus Delivery. For so long as, in the reasonable opinion of counsel for the Investor, the Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under
the Securities Act) is required to be delivered in connection with any acquisition or sale of Shares by the Investor, the Company will furnish to the Investor and its counsel (at the expense of the Company) copies of the Base Prospectus and all
Prospectus Supplements that are filed with the Commission, in each case, in the form filed with the Commission, as soon as reasonably practicable via e-mail in “.pdf” format to an e-mail account designated by the Investor and, at the
Investor’s request, will also furnish copies of the Base Prospectus and all Prospectus 

  
 32 









 
Supplements, in each case, in the form filed with the Commission, to each exchange or market on which sales of the Shares may be made and to each Broker-Dealer or other Person designated by the
Investor. The Company consents to the use of the Prospectus (and of any Prospectus Supplement thereto) in accordance with the provisions of the Securities Act and with the securities or “Blue Sky” laws of the jurisdictions in which the
Shares may be sold by the Investor, in connection with the offering and sale of the Shares and for such period of time thereafter as the Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is required by
the Securities Act to be delivered in connection with sales of the Shares. If during such period of time any event shall occur that in the judgment of the Company and its counsel is required to be set forth in the Registration Statement or the
Prospectus or any Permitted Free Writing Prospectus or should be set forth therein in order to make the statements made therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading, or if it is
necessary to amend the Registration Statement or supplement or amend the Prospectus or any Permitted Free Writing Prospectus to comply with the Securities Act or any other applicable law or regulation, the Company shall forthwith prepare and,
subject to Section 5.8 above, file with the Commission an appropriate amendment to the Registration Statement or Prospectus Supplement to the Prospectus (or supplement to the Permitted Free Writing Prospectus) and shall expeditiously furnish or
make available to the Investor a copy thereof in accordance with this Section 5.9. The Investor shall comply with any Prospectus delivery requirements under the Securities Act applicable to it. The Investor acknowledges and agrees that it is
not authorized to give any information or to make any representation not contained in the Prospectus or the documents incorporated by reference or specifically referred to therein in connection with the offer and sale of the Shares. 

Section 5.10 Selling Restrictions. 
 (i) Except as expressly set forth below, the Investor covenants that from and after the date hereof through and including the 90th day next following the termination of this Agreement (the
“Restricted Period”), neither the Investor nor any of its Affiliates nor any entity managed or controlled by the Investor (collectively, the “Restricted Persons” and each of the foregoing is referred to herein as a
“Restricted Person”) shall, directly or indirectly, (x) engage in any Short Sales involving the Company’s securities or (y) grant any option to purchase, or acquire any right to dispose of or otherwise dispose for
value of, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for any shares of Common Stock, or enter into any swap, hedge or other similar agreement that transfers, in whole or in part, the economic risk of
ownership of the Common Stock. Notwithstanding the foregoing, it is expressly understood and agreed that nothing contained herein shall (without implication that the contrary would otherwise be true) prohibit any Restricted Person during the
Restricted Period from: (1) selling “long” (as defined under Rule 200 promulgated under Regulation SHO) any shares of Common Stock (including the Shares); or (2) selling a number of shares of Common Stock equal to (x) the
number of Shares that such Restricted Person is or may be obligated to purchase under a pending Fixed Request Notice and/or (y) the number of Shares that such Restricted Person may purchase under a pending Optional Amount, but, in each case,
has not yet taken possession of so long as such Restricted Person (or the Broker-Dealer, as applicable) delivers the Shares purchased pursuant to such Fixed Request Notice and/or Optional Amount to the purchaser thereof or the applicable
Broker-Dealer; provided, however, such Restricted Person (or the applicable Broker-Dealer, as applicable) shall not be required to so deliver any 

  
 33 









 
such Shares subject to such Fixed Request Notice or Optional Amount, as the case may be, if (a) such Fixed Request or Optional Amount, as the case may be, is terminated by mutual agreement
of the Company and the Investor and, as a result of such termination, no such Shares are delivered to the Investor under this Agreement or (b) the Company otherwise fails to deliver such Shares to the Investor on the applicable Settlement Date
upon the terms and subject to the provisions of this Agreement. 
 (ii) In addition to the foregoing, in connection with any
sale of Shares (including any sale permitted by paragraph (i) above), the Investor shall comply in all respects with all applicable laws, rules, regulations and orders, including, without limitation, the requirements of the Securities Act and
the Exchange Act. 
 Section 5.11 Effective Registration Statement. The Company shall use its reasonable best
efforts to keep the Registration Statement effective pursuant to Rule 415 promulgated under the Securities Act, and to keep the Registration Statement and the Prospectus current and available for issuances and sales of Shares by the Company to the
Investor, and for the resale of Shares by the Investor, at all times during the term of this Agreement and, to the extent the Investor owns any Shares upon the termination of this Agreement, until the 180th day next following the termination of this
Agreement (the “Registration Period”). Without limiting the generality of the foregoing, during the Registration Period, the Company shall prepare and, subject to Section 5.8 above, file with the Commission, at the
Company’s expense, such amendments (including, without limitation, post-effective amendments) to the Registration Statement and such Prospectus Supplements pursuant to Rule 424(b) under the Securities Act, in each case, as may be necessary to
keep the Registration Statement effective pursuant to Rule 415 promulgated under the Securities Act, and to keep the Registration Statement and the Prospectus current and available for issuances and sales of Shares by the Company to the Investor,
and for the resale of Shares by the Investor, at all times during the Registration Period. Without limiting the generality of the foregoing, if, immediately prior to the third (3rd) anniversary of the initial effective date of the Registration
Statement (the “Renewal Date”), any of the Shares that have been or may be issued pursuant to this Agreement have not been issued by the Company or resold by the Investor and the Registration Period has not expired, the Company
will, prior to the Renewal Date, file a new Registration Statement relating to the Shares, in a form satisfactory to the Investor and its counsel, and, if such Registration Statement is not an automatic shelf registration statement on Form S-3ASR,
will use its reasonable best efforts to cause such Registration Statement to be declared effective within 180 days after the Renewal Date. The Company will take all other reasonable actions necessary or appropriate to permit the public offer and
sale of the Shares (and the resale thereof by the Investor) to continue as contemplated in the expired Registration Statement relating to the Shares. From and after the effective date thereof, references herein to the “Registration
Statement” shall include such new Registration Statement. 
 Section 5.12 Non-Public Information.
Neither the Company, nor any of its respective directors, officers, employees or agents shall disclose any material non-public information about the Company to the Investor, unless a simultaneous public announcement thereof is made by the Company in
the manner contemplated by Regulation FD. In the event of a breach of the foregoing covenant by the Company, or any of its respective directors, officers, employees and agents (as determined in the reasonable good faith judgment of the Investor),
the Investor shall 

  
 34 









 
give prompt written notice of such breach to the Company requesting that the Company make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material,
non-public information. If the Company does not make such public disclosure of such material, non-public information promptly, and in any case within 24 hours following receipt of such written notice, in addition to any other remedy provided in this
Agreement, the Investor shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material, non-public information without the prior approval by the Company or any of its respective
directors, officers, employees or agents. The Investor shall not have any liability to the Company or any of its respective directors, officers, employees, stockholders or agents, for any such disclosure. 

Section 5.13 Broker/Dealer. The Investor shall use one or more broker-dealers to effectuate all sales, if any, of the
Shares that it may acquire or purchase from the Company pursuant to this Agreement which (or whom) shall be unaffiliated with the Investor and FWG and not then currently engaged or used by the Company (collectively, the
“Broker-Dealer”). The Investor shall provide the Company with all information regarding the Broker-Dealer reasonably requested by the Company. The Investor shall be solely responsible for all fees and commissions of the
Broker-Dealer, which shall not exceed customary brokerage fees and commissions. 
 Section 5.14 Earnings
Statement. The Company will make generally available to its security holders as soon as practicable, but in any event not later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement covering a
12-month period that satisfies the provisions of Section 11(a) of and Rule 158 under the Securities Act. The terms “earnings statement” and “make generally available to its security holders” shall have the meanings set forth
in Rule 158 under the Securities Act. 
 Section 5.15 Disclosure Schedule. 

(i) From time to time during the Investment Period, the Company shall be permitted to update the Disclosure Schedule as may be required
to satisfy the condition set forth in Section 6.3(i). For purposes of this Section 5.15, any disclosure made in a schedule to the Compliance Certificate substantially in the form attached hereto as Exhibit D shall be deemed to be an
update of the Disclosure Schedule. Notwithstanding anything in this Agreement to the contrary, no update to the Disclosure Schedule pursuant to this Section 5.15 shall cure any breach of a representation or warranty of the Company contained in
this Agreement and shall not affect any of the Investor’s rights or remedies with respect thereto. 
 (ii) Notwithstanding
anything to the contrary contained in the Disclosure Schedule or in this Agreement, the information and disclosure contained in any Schedule of the Disclosure Schedule shall be deemed to be disclosed and incorporated by reference in any other
Schedule of the Disclosure Schedule as though fully set forth in such Schedule for which applicability of such information and disclosure is readily apparent on its face. The fact that any item of information is disclosed in the Disclosure Schedule
shall not be construed to mean that such information is required to be disclosed by this Agreement. Except as expressly set forth in this Agreement, such information and the thresholds (whether based on quantity, qualitative characterization, dollar
amounts or otherwise) set forth herein shall not be used as a basis for 

  
 35 









 
interpreting the terms “material” or “Material Adverse Effect” or other similar terms in this Agreement.

Company or the Investor pursuant to Section 7.1 or 7.2, as applicable, written notice thereof shall forthwith be given to the other party as provided in Section 9.4 and the transactions contemplated by this Agreement shall be terminated

 ARTICLE VIII 

INDEMNIFICATION 
 Section 8.1 General Indemnity. 
 (i) Indemnification by
the Company. The Company shall indemnify and hold harmless the Investor, each of its directors, officers, partners, employees and Affiliates, and each Person, if any, who controls the Investor within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act from and against all losses, claims, damages, liabilities and expenses (including reasonable costs of defense and investigation and all reasonable


  
 42 









 
attorneys’ fees) to which the Investor and each such other Person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities and expenses
arise out of or are based upon (a) any violation of United States federal or state securities laws or the rules and regulations of the Trading Market in connection with the transactions contemplated by this Agreement by the Company or any of
its affiliates, officers, directors or employees, (b) any untrue statement or alleged untrue statement of a material fact contained, or incorporated by reference, in the Registration Statement or any amendment thereto or any omission or alleged
omission to state therein, or in any document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein not misleading, or (c) any untrue statement or alleged untrue statement
of a material fact contained, or incorporated by reference, in the Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or in any “issuer information” (as defined in Rule 433 under the
Securities Act) of the Company, which “issuer information” is required to be, or is, filed with the Commission or otherwise contained in any Free Writing Prospectus, or any amendment or supplement thereto, or any omission or alleged
omission to state therein, or in any document incorporated by reference therein, 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;
provided, however, that (A) the Company shall not be liable under this Section 8.1(i) to the extent that a court of competent jurisdiction shall have determined by a final judgment (from which no further appeals are
available) that such loss, claim, damage, liability or expense resulted directly and solely from any such acts or failures to act, undertaken or omitted to be taken by the Investor or such Person through its bad faith or willful misconduct,
(B) the foregoing indemnity shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission
made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Investor expressly for use in the Current Report or any Prospectus Supplement or Permitted Free Writing Prospectus, or any amendment
thereof or supplement thereto, and (C) with respect to the Prospectus, the foregoing indemnity shall not inure to the benefit of the Investor or any such Person from whom the Person asserting any loss, claim, damage, liability or expense
purchased Common Stock, if copies of all Prospectus Supplements required to be filed pursuant to Section 1.4, together with the Base Prospectus, were timely delivered or made available to the Investor pursuant hereto and a copy of the Base
Prospectus, together with a Prospectus Supplement (as applicable), was not sent or given by or on behalf of the Investor or any such Person to such Person, if required by law to have been delivered, at or prior to the written confirmation of the
sale of the Common Stock to such Person, and if delivery of the Base Prospectus, together with a Prospectus Supplement (as applicable), would have cured the defect giving rise to such loss, claim, damage, liability or expense. 

The Company shall reimburse the Investor and each such controlling Person promptly upon demand (with accompanying presentation of
documentary evidence) for all legal and other costs and expenses reasonably incurred by the Investor or such indemnified Persons in investigating, defending against, or preparing to defend against any such claim, action, suit or proceeding with
respect to which it is entitled to indemnification. 
 (ii) Indemnification by the Investor. The Investor shall
indemnify and hold harmless the Company, each of its directors, officers, employees and Affiliates, and each Person, 

  
 43 









 
if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act from and against all losses, claims, damages, liabilities
and expenses (including reasonable costs of defense and investigation and all reasonable attorneys fees) to which the Company and each such other Person may become subject, under the Securities Act or otherwise, insofar as such losses, claims,
damages, liabilities and expenses arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Current Report, the Registration Statement or any Prospectus Supplement or Permitted Free Writing
Prospectus, or in any amendment thereof or supplement thereto, or any omission or alleged omission to state therein 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, in each case, to the extent, but only to the extent, the untrue statement, alleged untrue statement, omission or alleged omission was made in reliance upon, and in conformity with, written information furnished by the
Investor to the Company expressly for inclusion in the Current Report, the Registration Statement or such Prospectus Supplement or Permitted Free Writing Prospectus, or any amendment thereof or supplement thereto. 

The Investor shall reimburse the Company and each such director, officer or controlling Person promptly upon demand for all legal and
other costs and expenses reasonably incurred by the Company or such indemnified Persons in investigating, defending against, or preparing to defend against any such claim, action, suit or proceeding with respect to which it is entitled to
indemnification. 
 Section 8.2 Indemnification Procedures. Promptly after a Person receives notice of a
claim or the commencement of an action for which the Person intends to seek indemnification under Section 8.1, the Person will notify the indemnifying party in writing of the claim or commencement of the action, suit or proceeding;
provided, however, that failure to notify the indemnifying party will not relieve the indemnifying party from liability under Section 8.1, except to the extent it has been materially prejudiced by the failure to give notice. The
indemnifying party will be entitled to participate in the defense of any claim, action, suit or proceeding as to which indemnification is being sought, and if the indemnifying party acknowledges in writing the obligation to indemnify the party
against whom the claim or action is brought, the indemnifying party may (but will not be required to) assume the defense against the claim, action, suit or proceeding with counsel satisfactory to it. After an indemnifying party notifies an
indemnified party that the indemnifying party wishes to assume the defense of a claim, action, suit or proceeding, the indemnifying party will not be liable for any legal or other expenses incurred by the indemnified party in connection with the
defense against the claim, action, suit or proceeding except that if, in the opinion of counsel to the indemnifying party, one or more of the indemnified parties should be separately represented in connection with a claim, action, suit or
proceeding, the indemnifying party will pay the reasonable fees and expenses of one separate counsel for the indemnified parties. Each indemnified party, as a condition to receiving indemnification as provided in Section 8.1, will cooperate in
all reasonable respects with the indemnifying party in the defense of any action or claim as to which indemnification is sought. No indemnifying party will be liable for any settlement of any action effected without its prior written consent.
Notwithstanding the foregoing sentence, if at any time an indemnified party that is entitled to reimbursement pursuant to this Article VIII shall have requested (by written notice provided in accordance with Section 9.4) an indemnifying party
to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall 

  
 44 









 
be liable for any settlement of the nature contemplated hereby effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received written notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party
shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party will, without the prior written consent of the indemnified party, effect any settlement of a pending or
threatened action with respect to which an indemnified party is, or is informed that it may be, made a party and for which it would be entitled to indemnification, unless the settlement includes an unconditional release of the indemnified party from
all liability and claims which are the subject matter of the pending or threatened action. 
 If for any reason the
indemnification provided for in this Agreement is not available to, or is not sufficient to hold harmless, an indemnified party in respect of any loss or liability referred to in Section 8.1 as to which such indemnified party is entitled to
indemnification thereunder, each indemnifying party shall, in lieu of indemnifying the indemnified party, contribute to the amount paid or payable by the indemnified party as a result of such loss or liability, (i) in the proportion which is
appropriate to reflect the relative benefits received by the indemnifying party, on the one hand, and by the indemnified party, on the other hand, from the sale of Shares which is the subject of the claim, action, suit or proceeding which resulted
in the loss or liability or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above, but also the
relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, with respect to the statements or omissions which are the subject of the claim, action, suit or proceeding that resulted in the loss or
liability, as well as any other relevant equitable considerations. 
 The remedies provided for in Section 8.1 and this
Section 8.2 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified Person at law or in equity. 
 ARTICLE IX 
 MISCELLANEOUS 

Section 9.1 Fees and Expenses. 
 (i) Each party shall bear its own fees and expenses related to the transactions contemplated by this Agreement; provided, however, that the Company shall pay, on or prior to the Effective

deliver the Shares (which have been approved for listing or quotation on the Trading Market, if such an approval is required for the listing or quotation thereof on the Trading Market) to the Investor on the applicable Settlement Date and such

Shares failed to be delivered; provided that the issuance thereof by the Company would not violate the Securities Act or any applicable U.S. federal or state securities laws), as partial damages for such failure and not as a penalty, an amount equal
to 2.0% of the payment required to be paid by the Investor on such Settlement Date (i.e., the sum of the Fixed Amount Requested and the Optional Amount Dollar Amount) for the initial 30 days following such Settlement Date until the Shares (which
have been approved for listing or quotation on the Trading Market, if such an approval is required for the listing or quotation thereof on the Trading Market) have been delivered, and an additional 2.0% for each additional 30-day period thereafter
until the Shares (which have been approved for listing or quotation on the Trading Market, if such an approval is required for the listing or quotation thereof on the Trading Market) have been delivered, which amount shall be prorated for such
periods less than 30 days, subject in all cases to the Exchange Cap (except to the extent the Exchange Cap shall be inapplicable as expressly provided in Sections 2.12 and 2.13). Nothing in this Section 9.1(ii) shall be deemed to release the
Company from any liability for any breach under this Agreement, or to impair the rights of the Investor to compel specific performance by the Company of its obligations under this Agreement. 

Section 9.2 Specific Enforcement, Consent to Jurisdiction, Waiver of Jury Trial. 

(i) The Company and the Investor acknowledge and agree that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that either party shall be entitled to an injunction or injunctions to prevent or cure breaches of the provisions of this
Agreement by the other party and to enforce specifically the terms and provisions hereof (without the necessity of showing economic loss and without any bond or other security being required), this being in addition to any other remedy to which
either party may be entitled by law or equity. 
 (ii) Each of the Company and the Investor (a) hereby irrevocably submits
to the jurisdiction of the U.S. District Court and other courts of the United States sitting in the City and State of New York, Borough of Manhattan, for the purposes of any suit, action or proceeding arising out of or relating to this Agreement,
and (b) hereby waives, and agrees not to assert in any such suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of such court, that the suit, action or proceeding is brought in an inconvenient forum or
that the venue of the suit, action or proceeding is improper. Each of the Company and the Investor consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices
to it under this Agreement and agrees that such

 Section 9.6 Headings; Construction. The article, section and subsection headings in
this Agreement are for convenience only and shall not constitute a part of this Agreement for any other purpose and shall not be deemed to limit or affect any of the provisions hereof. Unless the context clearly indicates otherwise, each pronoun

each of them and their respective counsel has reviewed and had an opportunity to revise this Agreement and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be
employed in the interpretation of this Agreement. In addition, each and every reference to share prices and shares of Common Stock in this Agreement shall be subject to adjustment for any stock splits, stock combinations, stock dividends,

Section 9.7 Successors and Assigns. The Investor may not assign this Agreement to any Person without the prior consent
of the Company, in the Company’s sole discretion. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and assigns. The assignment by a party to this Agreement of any rights hereunder shall not
affect the obligations of such party under this Agreement. 
 Section 9.8 Governing Law. This Agreement shall
be governed by and construed in accordance with the internal procedural and substantive laws of the State of New York, without giving effect to the choice of law provisions of such state that would cause the application of the laws of any other
jurisdiction. 
 Section 9.9 Survival. The representations, warranties, covenants and agreements of the
Company and the Investor contained in this Agreement shall survive the execution and delivery hereof until the termination of this Agreement; provided, however, that (i) the provisions of Article VII (Termination), Article VIII

effective when all counterparts have been signed by each party and delivered to the other parties hereto, it being understood that all parties hereto need not sign the same counterpart. In the event any signature is delivered by facsimile, digital
or electronic transmission, such transmission shall constitute delivery of the manually executed original and the party using such means of delivery shall thereafter cause four additional executed signature pages to be physically delivered to the
other parties within five days of the execution and delivery hereof. Failure to provide or delay in the delivery of such additional executed signature pages shall not adversely affect the efficacy of the original delivery.

prior to issuance or filing, any press release, Commission filing or any other public disclosure made by or on behalf of the Company relating to the Investor, its purchases hereunder or any aspect of this Agreement or the transactions contemplated

competent jurisdiction shall determine that any one or more of the provisions or part of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision or part of a provision of this Agreement, and this Agreement shall be reformed and construed as if such invalid or illegal or unenforceable provision, or part of such provision, had never been
contained herein, so that such provisions would be valid, legal and enforceable to the maximum extent possible. 

Section 9.13 No Third Party Beneficiaries. Except as expressly provided in Article VIII, this Agreement is intended
only for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.
