 Subject to Section 2(b), the Company shall use its best efforts to cause the Registration
Statement to be declared effective under the Securities Act (unless it becomes effective automatically upon filing) as promptly as possible after the filing thereof (but such effectiveness date shall not be later than the Effectiveness Date), and

file a Rule 424(b) prospectus with the Commission. 
 (b) If: (1) the Registration Statement is not filed on or prior to the Filing Date
(it being understood that if the Company files the Registration Statement without affording the Investors the opportunity to review and comment on the same as required by Section 3(c), the Company shall not be deemed to have satisfied
Section 2(b)(1)); or (2) the Registration Statement does not become automatically effective or is not declared effective by the Commission on or before the Effectiveness Date, (3) the Company fails to file a Rule 424(b)
prospectus in accordance with Section 2(a) above (whether or not such a prospectus is technically required by such rule), (4) after the Effective Date (other than during an Allowable Grace Period) a Registration Statement ceases for any
reason to remain continuously effective as to all Registrable Shares for which it is required to be effective or the Investors are not permitted to utilize the Prospectus therein to resell such Registrable Shares, or (5) the Company’s
Common Stock is suspended, delisted (including a failure to timely list the Registrable Shares) or fails to be quoted on any Trading Market while Registrable Shares are still held by any Investor (provided that any such suspension, delisting or
failure to be quoted which did not directly arise out of or result from any action or inaction of the Company shall not be deemed to be a suspension or delisting for purposes of this clause (5)) (any such failure or breach being referred to as
an “Event,” and for purposes of Section 2(b)(1), Section 2(b)(2), Section 2(b)(3), Section 2(b)(4) or Section 2(b)(5) the date on which such breach occurs, and for purposes
of Section 2(b)(4) if an Allowable Grace Period applied, the date on which the Allowable Grace Period is exceeded, being referred to as an “Event Date”), then in addition to any other rights or remedies the Investors may
have hereunder or under applicable law, each Investor shall receive from the Company, on the Event Date and each thirty (30) day anniversary of the Event Date until the applicable Event is cured, as partial damages and not as a penalty, cash in
an amount equal to 1.0% of the Aggregate Purchase Price (as defined in the Subscription Agreements) paid by such Investor pursuant to such Investor’s Subscription Agreement. For purposes of the preceding sentence, the applicable Event shall be
deemed to be cured on: (A) in the case of Section 2(b)(1), 

  

 5 

 
the date on which such Registration Statement is filed, (B) in the case of Section 2(b)(2), the date on which such Registration Statement
becomes effective, (C) in the case of Section 2(b)(3), the date on which such prospectus is filed, (D) in the case of Section 2(b)(4), the date on which such Registration Statement becomes effective again or any
Prospectus becomes usable again, as applicable, and (E) in the case of Section 2(b)(5), the date on which the Common Stock is listed or quoted or again listed or quoted on a Trading Market or on which the suspension ends (as the
case may be). Such payments shall be made to each Investor in cash not later than three (3) Business Days following the Event Date or end of each thirty (30) calendar day period, as applicable. If an Event is cured prior to any thirty
(30) day anniversary of the applicable Event Date, then such payment shall be made to each Investor in cash not later than three (3) Business Days following such cure. If the Company fails to pay any partial damages pursuant to this
Section in a timely manner to any Investor, the Company will pay interest thereon at a rate of 1.5% per month (or such lesser maximum amount that is permitted to be paid by applicable law) to such Investor, accruing daily from the date such
partial damages are due until such amounts, plus all such interest thereon, are paid in full. The partial damages pursuant to the terms hereof shall apply on a daily pro rata basis for any portion of a month prior to the cure of an Event.

 (c) In the event that, in the good faith judgment of the Company’s Board of Directors, it is advisable to suspend use of an effective
Registration Statement or Prospectus therein due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company’s Board of Directors believes public disclosure would be detrimental to the
Company, (i) the Company shall notify all Stockholders to such effect, and, upon receipt of such notice, (ii) each of the Stockholders shall immediately discontinue any sales of Registrable Shares pursuant to such
Registration Statement and/or Prospectus until each of such holders has received copies of a supplemented or amended prospectus or until the holders are advised in writing by the Company that the then current prospectus may be used and has
received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such prospectus (such period is referred to herein as a “Grace Period”). Notwithstanding anything to the
contrary in this Section 2(c), no Grace Period shall exceed fifteen (15) consecutive days and during any three hundred sixty five (365) day period such Grace Periods shall not exceed an aggregate of thirty (30) days and no Grace
Period may begin until at least six (6) months have passed since any previous Grace Period (regardless of the length of such previous Grace Period) (each, an “Allowable Grace Period”); provided, that no Allowable Grace
Period may exist during the first thirty (30) Business Days after the Effective Date of the applicable Registration Statement. For purposes of determining the length of a Grace Period above, the Grace Period shall begin on and include the date
the Stockholders receive the notice referred to in (i) above and shall end on and include the later of the date the Stockholders receive the supplemented or amended prospectus or notice (as the case may be) referred to in clause (ii) and
the date referred to in such notice. 
 (d) Notwithstanding anything to the contrary contained in this Agreement but subject to the payment
of partial liquidated damages pursuant to Section 2(b), in the event the staff of the Commission (the “Staff”) or the Commission seeks to characterize any offering pursuant to a Registration Statement filed pursuant to
this Agreement as constituting an offering of securities by or on behalf of the Company, or in any other manner, such that the Staff or the Commission do not permit such Registration Statement to become effective and used for
resales in a manner that does not constitute such an offering and that permits the continuous resale at the market by the Stockholders participating therein (or as otherwise may be acceptable to each 

  

 6 

 
Stockholder) without being named therein as an “underwriter,” then the Company shall reduce the number of shares to be included in such
Registration Statement by all Stockholders (subject to the priorities set forth in the remainder of this paragraph) until such time as the Staff and the Commission shall so permit such Registration Statement to become effective as
aforesaid. In making such reduction, the Company shall first reduce or eliminate the shares to be included by the Placement Agents. If, following such reduction, such characterization still exists, the Company shall then reduce the number of
shares to be included by all other Stockholders on a pro rata basis (based upon the number of Registrable Shares otherwise required to be included for each such Stockholder) unless the inclusion of shares by a particular Stockholder or a particular
set of Stockholders are resulting in the Staff or the Commission’s “by or on behalf of the Company” offering position, in which event the shares held by such Stockholder or set of Stockholders shall be the only shares subject to
reduction (and if by a set of Stockholders on a pro rata basis by such Stockholders or on such other basis as would result in the exclusion of the least number of shares by all such Stockholders). In addition, in the event that the Staff or the
Commission requires any Stockholder seeking to sell securities under a Registration Statement filed pursuant to this Agreement to be specifically identified as an “underwriter” in order to permit such Registration
Statement to become effective, and such Stockholder does not consent to being so named as an underwriter in such Registration Statement, then, in each such case, the Company shall reduce the total number of Registrable Shares to be
registered on behalf of such Stockholder, until such time as the Staff or the Commission does not require such identification or until such Stockholder accepts such identification and the manner thereof. Following the reduction
or elimination of shares to be included by the Placement Agents, any reduction of shares on behalf of the any other Stockholder pursuant to this paragraph will first reduce all Warrant Shares held by such Stockholder. In the event of
any reduction in Registrable Shares pursuant to this paragraph, an affected Stockholder (other than a Placement Agent) shall have the right to require, upon delivery of a written request to the Company signed by such Stockholder, the
Company to file a registration statement within 30 days of such request (subject to any restrictions imposed by Rule 415 or required by the Staff or the Commission) for resale by such Stockholder in a manner acceptable to such Stockholder,
and the Company shall following such request cause to be and keep effective such registration statement in the same manner as otherwise contemplated in this Agreement for a Registration Statements hereunder, in each case until such
time as: (i) all Registrable Shares held by such Stockholder have been registered pursuant to an effective Registration Statement in a manner acceptable to such Stockholder and disposed of thereunder or (ii) the Registrable
Shares may be resold by such Stockholder without restriction (including volume limitations) pursuant to Rule 144(k) of the Securities Act (taking account of any Staff position with respect to “affiliate” status) or (iii) such
Stockholder agrees to be named as an underwriter in any such Registration Statement in a manner acceptable to such Stockholder as to all Registrable Shares held by such Stockholder and that have not theretofore been included in a Registration
Statement under this Agreement and have been disposed of thereunder (it being understood that the special demand right under this sentence may be exercised by a Stockholder multiple times and with respect to limited amounts of Registrable Shares in
order to permit the resale thereof by such Stockholder as contemplated above). Any additional registration statement filed pursuant to this Section 2(d) shall be subject to the provisions of Section 2(b). 
 (e) In the event that Form S-3 is not available for the registration of the resale of Registrable Shares hereunder, the Company shall (i) register
the resale of the Registrable Shares on another appropriate form reasonably acceptable to a majority in interest of the 

  

 7 

 
Investors and (ii) undertake to register the Registrable Securities on Form S-3 as soon as such form is available, provided that the Company
shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Shares has been declared effective by the Commission. 
 Section 3. Preparation and Filing. 
 If and whenever the Company is under an obligation pursuant to the provisions of the Agreement to effect the registration of any Registrable Shares, the Company shall, as expeditiously as practicable: 
 (a) mail the Electing Holder Questionnaire to each of the Stockholders. No Stockholder shall be entitled to be named as a selling security holder in the
Registration Statement as of the Effective Date, and no Stockholder shall be entitled to use the Prospectus for resales of Registrable Shares at any time unless such Stockholder has returned a completed and signed Electing Holder Questionnaire to
the Company by the deadline for response as specified in such Electing Holder Questionnaire in accordance with Section 2(a); provided, however, Stockholders shall have at least ten (10) calendar days from the date on
which the Electing Holder Questionnaire is first mailed to such Stockholder to return a completed and signed Electing Holder Questionnaire to the Company. The term “Electing Holder” shall mean any Stockholder that has returned a
completed and signed Electing Holder Questionnaire to the Company in accordance with this Section 3(a); 
 (b) use its best
efforts to cause a registration statement that registers such Registrable Shares to become and remain effective until all of such Registrable Shares have been disposed of; 
 (c) furnish, at least five (5) Business Days before filing of the Registration Statement or other registration statement that registers such
Registrable Shares, the Prospectus or other prospectus relating thereto or any amendments or supplements relating to such a registration statement or prospectus, to the Electing Holders and any counsel of such holders copies of all such documents
proposed to be filed which documents shall be subject to review thereof. If any such Registration Statement refers to any Electing Holder by name or otherwise as the holder of any securities of the Company, then such Electing Holder shall have the
right to require (i) the insertion therein of language, in form and substance reasonably satisfactory to such Electing Holder, to the effect that the holding by such Electing Holder of such securities is not to be construed as a recommendation
by such Electing Holder of the investment quality of the Company’s securities covered thereby or (ii) in the event that such reference to such Electing Holder by name or otherwise is not required by the Securities Act or any similar
federal statute then in force, the deletion of the reference to such Electing Holder in any amendment or supplement to the Registration Statement filed or prepared subsequent to the time such reference ceases to be required. The Company shall also
make all reasonable changes as proposed by any Electing Holder or its counsel. Without limiting Section 5.2 of the Subscription Agreements, in no event shall the Company provide any material, non-public information regarding the Company or any
of its Subsidiaries in connection with the registration of any Registrable Shares;

amendments and supplements to such registration statement and the prospectus used in connection therewith as may be

registration statement effective until all of such Registrable Shares have been disposed of and to comply with the provisions of the Securities Act with respect to the sale or other disposition of such Registrable Shares; cause the related
Prospectus or other prospectus to be amended or supplemented by any required prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; and respond as promptly as reasonably possible to any comments received from the
Commission with respect to such Registration Statement or other registration statement or any amendment thereto; 
 (e) notify the Electing
Holders immediately at any time when a prospectus relating to such Registrable Shares or any document related thereto includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then existing and, at the request of the Electing Holders prepare and furnish to such Electing Holders a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the offerees of such shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then existing; 
 (f) from the date hereof until all of such
Registrable Shares have been disposed of, the Company shall (subject to Section 2(c)) promptly take such action as may be necessary, including preparing a post-effective amendment or supplement to the Registration Statement or
Prospectus, or any document incorporated therein by reference, so that (i) each of the Registration Statement and any amendment thereto and the Prospectus and any amendment or supplement thereto (and each report or other document incorporated
by reference therein in each case) complies in all respects with the Securities Act and the Exchange Act and the respective rules and regulations thereunder, (ii) each of the Registration Statement and any amendment thereto does not, when it
becomes effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading
and (iii) each of the Prospectus and any amendment or supplement to the Prospectus does not at any time prior to the disposal of all of such Registrable Shares include an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; 
 (g)
notify in writing the Stockholders participating in such registration and their counsel (i) of the receipt by the Company of any notification with respect to any comments by the Commission with respect to such registration statement or
prospectus or any amendment or supplement thereto or any request by the Commission for the amending or supplementing thereof or for additional information with respect thereto, (ii) of the receipt by the Company of any notification with respect
to the issuance by the Commission of any stop order suspending the effectiveness of such registration statement or prospectus or any amendment or supplement thereto or the initiation or threatening of any proceeding for that purpose, (iii) of
the receipt by the Company of any notification with respect to the suspension of the qualification of such Registrable Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purposes and (iv) of the
existence of any fact or the happening of any event that causes the Company to become an “ineligible issuer,” as defined in Rule 405; 
  

 9 

 (h) use its best efforts to register or qualify such Registrable Shares under such other securities or
blue sky laws of such jurisdictions as the Stockholders reasonably request and do any and all other acts and things which may be reasonably necessary or advisable to enable such Stockholders to consummate the disposition in such jurisdictions of the

where it would not otherwise be required to do so but for this Section 3(h); 
 (i) without limiting Section 3(h),

 (j) use its best efforts to avoid the issuance of, or, if issued, obtain the
withdrawal of (i) any order suspending the effectiveness of the Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Shares for sale in any jurisdiction, at the
earliest practicable moment; 
 (k) furnish to the Electing Holders such number of copies of a summary prospectus, if any, or other
prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Electing Holders may reasonably request in order to facilitate the public sale or other disposition of such
Registrable Shares;

prospectus supplement or post-effective amendment as soon as practicable after it is notified of the matters to be included or incorporated in such prospectus supplement or post-effective amendment; 
  

 10 

 (m) if an Electing Holder is or is to be identified by the Commission or the NASD as an
“underwriter”, at the request of such Electing Holder, the Company shall (A) furnish to such Electing Holder, on the date of the effectiveness of the Registration Statement and thereafter from time to time on such dates as such

requested by such holder; 
  

 11 

 (r) otherwise use its best efforts to take all other steps necessary to effect the registration of such
Registrable Shares contemplated hereby; and 
 (s) in connection with the due diligence efforts of any Electing Holder who is or is to be
identified as an “underwriter,” the Company shall make available for inspection during business hours and upon reasonable advance request by (i) any Electing Holder, (ii) counsel for such Electing Holder and (iii) one firm
of accountants or other agents retained by such Electing Holder (collectively, the “Deemed Underwriter Inspectors”), all Records, as shall be reasonably deemed necessary by each Deemed Underwriter Inspector, and cause the
Company’s officers, directors and employees to supply all information which any Deemed Underwriter Inspector may reasonably request. 
 The Company shall not permit any officer, director, underwriter, broker or any other Person acting on behalf of the Company to use any Free Writing Prospectus in connection with the Registration Statement covering Registrable Shares,
without the prior written consent of the holders of a majority of the Registrable Shares, which consent shall not be unreasonably withheld or delayed. Any consent to the use of a Free Writing Prospectus included in an underwriting agreement to which
the Electing Holders are parties shall be deemed to satisfy the requirement for such consent. Each Stockholder, upon receipt of any notice from the Company of any event of the kind described in Sections 3(e) or 3(g), shall forthwith
discontinue disposition of the Registrable Shares pursuant to the registration statement covering such Registrable Shares, subject to the payment of partial damages otherwise required by Section 2(b), until such holder’s receipt of
the copies of the supplemented or amended prospectus contemplated by Sections 3(e) or 3(g), and, if so directed by the Company, such Stockholder shall deliver to the Company all copies, other than permanent file copies then in such
holder’s possession, of the prospectus covering such Registrable Shares at the time of receipt of such notice. 
 Section 4.
Expenses. 
 All expenses incurred by the Company, and all expenses separately incurred by the Stockholders, in complying with their
obligations pursuant to the Agreement and in connection with the registration and disposition of Registrable Shares, including, without limitation, all registration and filing fees (including all filing fees incident to filing with the NASD), fees
and expenses of complying with securities and blue sky laws, printing expenses, fees and expenses of the Company’s counsel and accountants and the Stockholder’s counsel shall be paid by the Company, including all underwriting fees and
expenses (including legal expenses and expenses of the Company’s other advisors); provided, however, that all underwriting discounts and selling commissions applicable to the Registrable Shares shall be borne by the Stockholders
selling such Registrable Shares in proportion to the number of such Registrable Shares sold by each such holder in the applicable underwritten offering. 
 Section 5. Indemnification. 
 (a) In connection with any registration of any Registrable Shares
under the Securities Act pursuant to the Agreement, the Company shall indemnify and hold harmless each 

  

 12 

 
Stockholder, each of such Stockholder’s officers, directors, employees, members, partners, and advisors and their respective Affiliates, each
underwriter, broker or any other Person acting on behalf of each Stockholder and each other Person, if any, who controls any of the foregoing Persons within the meaning of the Securities Act against any losses, claims, damages, liabilities, or
actions joint or several (or actions in respect thereof), to which any of the foregoing Persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise
out of or are based upon an untrue statement or allegedly untrue statement of a material fact contained in the registration statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final
prospectus contained therein or otherwise filed with the Commission, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Shares, or any Issuer Free Writing Prospectus, or arise out of or
are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or, with respect to any prospectus, necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading, or any violation by the Company of the Securities Act or state securities or blue sky laws applicable to the Company or relating to action or inaction required of the Company
in connection with such registration or qualification under such state securities or blue sky laws; and shall promptly reimburse such Persons for any legal or other expenses reasonably incurred by any of them in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action
(including any legal or other expenses incurred) arises out of or is based solely upon an untrue statement or allegedly untrue statement or omission or alleged omission made in said registration statement, preliminary prospectus, final prospectus,
amendment, supplement, Issuer Free Writing Prospectus or document incident to registration or qualification of any Registrable Shares in reliance upon and in conformity with written information furnished to the Company by such Stockholder
specifically for use in the preparation thereof or for such Stockholders’ failure to deliver, if required to do so under applicable law, a prospectus, Issuer Free Writing Prospectus or for selling any shares of Common Stock pursuant to such
prospectus after the Company has provided to such Stockholder written notice of the Company’s receipt of a stop order relating to such Registration Statement or for selling any shares of Common Stock pursuant to such prospectus after the
Stockholder has received written notice pursuant to Sections 3(e) or 3(g) and prior to the Stockholder’s receipt of notification from the Company that such event has been cured or the Stockholder’s receipt from the Company of a
corrected prospectus, as applicable, and then only if and to the extent that following the receipt of such corrected prospectus the misstatement or omission giving rise to such loss, claim, damage, liability or action would have been corrected and
no grounds for such loss, claim, damage, liability or action would have existed. 
 (b) In connection with any registration of Registrable
Shares under the Securities Act pursuant to the Agreement, each Electing Holder shall, severally and not jointly, indemnify and hold harmless the Company, each director of the Company, each employee and advisor of the Company, each officer of the
Company who shall sign such registration statement, each underwriter, broker or other Person acting on behalf of the Stockholders, the Affiliates of each of the foregoing, and each Person who controls any of the foregoing Persons within the meaning
of the Securities Act with respect to any statement or omission from such registration statement, any preliminary prospectus or final prospectus contained therein or otherwise filed 

  

 13 

 
with the Commission, any amendment or supplement thereto or Issuer Free Writing Prospectus or any document incident to registration or qualification of any
Registrable Shares, in each case, to the extent (and only to the extent) such statement or omission was made in reliance upon and in conformity with written information furnished to the Company or such underwriter by such Electing Holder
specifically for use in connection with the preparation of such registration statement, preliminary prospectus, final prospectus, amendment, supplement, document or Issuer Free Writing Prospectus; provided, however, that the maximum
amount of liability in respect of such indemnification shall be limited, in the case of each Electing Holder, to an amount equal to the net proceeds actually received by such Electing Holder from the sale of Registrable Shares effected pursuant to
such registration that gave rise to such liability. 
 (c) Promptly after receipt by an indemnified party of notice of the commencement of
any action involving a claim referred to in this Section 5, such indemnified party will, if a claim in respect thereof is made against an indemnifying party, give written notice to the latter of the commencement of such action. The
failure of any indemnified party to notify an indemnifying party of any such action shall not (unless such failure shall have a material adverse effect on the indemnifying party) relieve the indemnifying party from any liability in respect of such
action that it may have to such indemnified party hereunder. In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other
indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided, however, that if any indemnified party shall have
reasonably concluded that there may be one or more legal or equitable defenses available to such indemnified party which are additional to or conflict with those available to the indemnifying party, or that such claim or litigation involves or could
have an effect upon matters beyond the scope of the indemnity agreement provided hereunder, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party (but shall have the right to
participate therein with counsel of its choice) and such indemnifying party shall reimburse such indemnified party and any Person controlling such indemnified party for that portion of the fees and expenses of any counsel retained by the indemnified
party which is reasonably related to the matters covered by the indemnity agreement provided hereunder. No indemnifying party shall, without the prior written consent of the indemnified party consent to entry of any judgment or enter into any
settlement or compromise; provided, however, that if the indemnifying party assumes the defense of a claim, the indemnified party shall consent to any settlement, compromise or discharge of a claim that the indemnifying party may recommend that has
as the sole remedy monetary damages, that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such claim, and that has no finding or admission of any violation of any law or regulation or of the
rights of any Person and no effect on any other claims that may be made against the indemnified party. If the indemnifying party is not entitled to, or elects not to, assume the defense of a claim, it will not be obligated to pay the fees and
expenses of more than one counsel with respect to such claim. 
 (d) If the indemnification provided for hereunder is held by a court of
competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party, in lieu of 

  

 14 

 
indemnifying such indemnified party hereunder, shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim,
damage, liability or action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions which resulted in such
loss, claim, damage, liability or action as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just and equitable if contribution pursuant hereto does not take account of the equitable considerations referred to herein. No
Person guilty or liable of fraudulent misrepresentation shall be entitled to contribution from any Person. 
 (e) Notwithstanding any other
provision of this Section 5, in no event will any Electing Holder be required to undertake any liability or obligation under this Section 5 for an aggregate amount in excess of the dollar amount of the net proceeds (after
deducting any fees, discounts and commissions applicable thereto) received by such Electing Holder from the sale of such Electing Holder’s Registrable Shares giving rise to such liability or obligation (net of all expenses paid by such holder
in connection with any claim relating to this Section 5 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission). 
 (f) The obligations of the Company under this Section 5 shall be in addition to any liability that the Company may otherwise have to any
indemnified party and the obligations of any indemnifying party under this Section 5 shall be in addition to any liability that such indemnifying party may otherwise have to the Company. The remedies provided in this
Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be available to an indemnified party at law or in equity. 
 Section 6. Free Writing Prospectus. Each Stockholder represents that it has not prepared or had prepared on its behalf or used or referred to or distributed, and agrees that it will not prepare or have
prepared on its behalf or use or refer to or, except as contemplated by the Agreement, distribute, any Free Writing Prospectus with respect to the sale of its Registrable Shares pursuant to the Registration Statement, in each case, without the prior
written consent of the Company not to be unnecessarily withheld and, in connection with any underwritten offering, the underwriters. Any such Free Writing Prospectus consented to by the Company and the underwriters, as the case may be, is
hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents and agrees that it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus,
including in respect of timely filing with the Commission, legending and record keeping. 
 Section 7. Exchange Act Compliance.

 The Company shall comply with all of the reporting requirements of the Exchange Act applicable to it and shall comply with all other public
information reporting requirements of the Commission which are conditions to the availability of Rule 144. The 

  

 15 

 
Company shall cooperate with the Stockholders in supplying such information as may be necessary for the Stockholders to complete and file any information
reporting forms presently or hereafter required by the Commission as a condition to the availability of Rule 144. The Company shall cause its counsel to issue a legal opinion to the Company’s transfer agent if required by the Company’s
transfer agent to effect the removal of any legend to the extent that such legend is permitted to be removed in accordance with the terms of Rule 144, the Agreement and the other applicable rules and regulations. 
 Section 8. Remedies. 
 The
Company acknowledges and agrees that any failure by the Company to comply with its obligations under the Agreement may result in material irreparable injury to the Stockholders for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event of any such failure, the Stockholders or any holder of Registrable Shares may obtain such relief as may be required to specifically enforce the Company’s obligations
hereunder. The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. Failure of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in
exercising such right or remedy, shall not operate as a waiver thereof. 
 Section 9. Benefits of Agreement; Third Party
Beneficiaries. 
 Except as provided herein, the Agreement shall bind and inure to the benefit of the Company, the Stockholders and
subject to Section 10, the respective successors and permitted assigns of the Company and the Stockholders. 
 Section 10.
Assignment. 
 Each Stockholder may assign its rights hereunder to any purchaser or transferee of Registrable Shares; provided,
however, that such purchaser or transferee shall, as a condition to the effectiveness of such assignment, be required to execute a counterpart to the Agreement agreeing to be treated as an Stockholder whereupon such purchaser or transferee
shall have the benefits and liabilities of, and shall be subject to the restrictions contained in, the Agreement as if such purchaser or transferee was originally included in the definition of an Stockholder herein and had originally been a party
hereto. 
 Section 11. Entire Agreement. 
 This Agreement, the Subscription Agreements, the Warrants and the other Transaction Documents constitute the entire agreement among the parties hereto and thereto with respect to the subject matter hereof and thereof.
This Agreement, the Subscription Agreements and the Warrants supersede all prior agreements and understandings with respect to the subject thereof. The language used in this Agreement will be deemed to be the language chosen by the parties to
express their mutual intent, and no rules of strict construction will be applied against any party. 
 Section 12. Other Registration
Rights. The Company will not, on or after the date of the Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Stockholders in the Agreement or otherwise conflicts with the
provisions hereof. The Company shall not permit any securities other than the Registrable Shares to be included in any Registration Statement. 
  

 16 

 Section 13. Piggyback Registrations. If, at any time during the period in which a
Registration Statement is required to be kept effective, there is not an effective Registration Statement covering all of the Registrable Shares and the Company shall determine to prepare and file with the Commission a registration statement
relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to
equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with the Company’s stock option or other employee benefit plans, then the Company shall deliver to
each Investor a written notice of such determination and, if within fifteen (15) days after the date of the delivery of such notice, any such Investor shall so request in writing, the Company shall include in such registration statement all or
any part of such Registrable Shares such Investor requests to be registered; provided, however, that the Company shall not be required to register any Registrable Shares pursuant to this Section 13 that are eligible for resale pursuant to Rule
144(k) promulgated by the Commission pursuant to the Securities Act or that are the subject of a then effective Registration Statement. 
 Section 14. Notices. 
 All notices, requests, consents and other communications hereunder shall be in writing, shall be
delivered (A) if within United States by first-class registered or certified airmail, or nationally recognized overnight express courier (with next day delivery specified), postage prepaid, or by facsimile, or (B) if delivered from outside

 Section 15. Modifications; Amendments; Waivers. 
 The terms and provisions of the Agreement may not be modified or
amended except pursuant to a writing signed by the Company and Stockholders holding at least a majority of all Registrable Shares then outstanding. Any waiver of any provision of the Agreement requested by any party hereto must be granted in
advance, in writing by the party granting such waiver; provided, however, that the holders of a majority of all then outstanding Registrable Shares may grant a waiver on behalf of all Stockholders. Notwithstanding anything to the
contrary in this Section 15, (a) no such modification, amendment or waiver shall reduce the percentage of Registrable Shares required to amend or modify the Agreement or the percentage 

  

 18 

 
of Registrable Shares required to waive the obligations of the Company or the rights of the Stockholders hereunder without the consent of each Stockholder,
and (b) any such modification, amendment or waiver that materially and adversely affects any Stockholder with respect to the rights or obligations in respect of such Stockholder’s Registrable Shares in a manner disproportionate to how it
materially and adversely affects the rights or obligations in respect of Registrable Shares of any other Stockholder shall not be effective without the prior written consent of such Stockholder. 
 Section 16. Counterparts. 
 This
Agreement may be executed in two or more counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute but one instrument, and shall become effective when one or more counterparts have been signed
by each party hereto and delivered to the other party. In the event that any executed signature page is delivered by facsimile transmission or by an e-mail in a .pdf file, such signature page shall create a valid and binding obligation of the party
executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof. 
 Section 17. Headings and Certain Terms. 
 The headings of the various sections of the Agreement have been inserted for
convenience of reference only and shall not be deemed to be a part of the Agreement. The terms “including,” “includes,” “include” and words of like import shall be construed broadly as if followed
by the words “without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like import refer to this entire Agreement instead of just the provision in which they are found.

 Section 18. Governing Law; Consent to Jurisdiction and Venue; Waiver of Jury Trial. 
 This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York, without giving effect to any of the
conflicts of law principles which would result in the application of the substantive law of another jurisdiction. 
 Each of the parties
hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or
judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as
are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. Each party hereto
irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an
inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
  

 19 

 Section 19. Severability. 
 It is the desire and intent of the parties that the provisions of the Agreement be enforced to the fullest extent permissible under the law and public
policies applied in each jurisdiction in which enforcement is sought. Accordingly, in the event that any provision of the Agreement would be held in any jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to
such jurisdiction, shall be ineffective, without invalidating the remaining provisions of the Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could
be more narrowly drawn so as to not be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of the Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction. 
 Section 20. Independent Nature of Stockholders’ Obligations and
Rights.  
 The obligations of each Stockholder hereunder are several and not joint with the obligations of any other Stockholder
hereunder, and no Stockholder shall be responsible in any way for the performance of the obligations of any other Stockholder hereunder. Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by
any Stockholder pursuant hereto or thereto, shall be deemed to constitute the Stockholders as a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Stockholders are in any way acting in
concert with respect to such obligations or the transactions contemplated by the Agreement. Each Stockholder shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of the Agreement, and
it shall not be necessary for any other Stockholder to be joined as an additional party in any proceeding for such purpose. Each Stockholder has been represented by its own separate legal counsel in their review and negotiation of the Agreement. The
Company has elected to provide all Stockholders with the same terms herein for the convenience of the Company and not because it was required or requested to do so by the Stockholders. 
 Section 21. Survival. The respective indemnities, agreements, representations, warranties and other provisions set forth in the Agreement or
made pursuant hereto shall remain in full force and effect, and shall survive the transfer and registration of the Registrable Shares of such Stockholder. 
 Section 22. Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates,
instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

in the form of the subscription notice attached as Exhibit A hereto or a reasonable facsimile thereof (the “Exercise Notice”), to the Company and the Company’s designated transfer agent (the “Transfer
Agent”), of such holder’s election to exercise all or a portion of this Warrant; and (ii) the payment of the aggregate Exercise Price to the Company by 

  

 4 

 
wire transfer or by certified bank check payable to the order of the Company in United States dollars or by notifying the Company that this Warrant is being
exercised pursuant to a Cashless Exercise (as defined below) (the items to be delivered pursuant to clauses (i) and (ii) above collectively are referred to herein as the “Exercise Delivery Documents”); provided,
however, that if such Warrant Shares are to be issued in any name other than that of the registered holder of this Warrant, such issuance shall be deemed a transfer and the provisions of Section 8 of this Warrant shall be applicable. The
holder shall not be required to deliver the original of this Warrant in order to effect an exercise hereunder. In the event of any exercise of the rights represented by this Warrant in compliance with this Section 2(a) and Section 2(c),
the Company shall, within three (3) Business Days after receipt of the Exercise Delivery Documents, (A) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities
Transfer Program, upon the request of the holder, credit such aggregate number of shares of Common Stock to which the holder is entitled pursuant to such exercise to the holder’s or its designee’s balance account with DTC through its
Deposit Withdrawal Agent Commission system or (B) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address specified in the Exercise Notice, a certificate or certificates
in such denominations as may be requested by the holder in the Exercise Notice, registered in the name of the holder or its designee, for the number of shares of Common Stock to which the holder shall be entitled upon such exercise. Upon delivery of
the Exercise Delivery Documents, the holder of this Warrant shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of
delivery the certificates evidencing such Warrant Shares. 
 If the Company shall
fail, for any reason or for no reason, to issue to the holder within three (3) Business Days of receipt of the Exercise Delivery Documents, a certificate for the number of shares of Common Stock to which the holder is entitled and register such
shares of Common Stock on the Company’s share register or to credit the holder’s balance account with DTC for such number of shares of Common Stock to which the holder is entitled upon the holder’s exercise of this Warrant (as the
case may be), then, in addition to all other remedies available to the holder, and if on or after such third (3rd) Business Day the holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the holder of shares of Common Stock issuable upon such exercise that the holder
anticipated receiving from the Company (a “Buy-In”), then, in addition to all other rights and remedies available to the holder, the Company shall, within three (3) Business Days after the holder’s request and in the
holder’s discretion, either (i) pay cash to the holder in an amount equal to the holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In
Price”), at which point the Company’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 holder a certificate or certificates
representing such shares of Common Stock or credit the holder’s balance account with DTC for the number of shares of Common Stock to which the holder is entitled upon such holder’s exercise hereunder (as the case may be) and pay cash to
the holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock times (B) the VWAP of the Common Stock for the five (5) Trading Day period immediately preceding
the date of the Exercise Notice. 
 (b) Unless the rights represented by this Warrant shall not have taken effect, shall have 

  

 5 

 
expired or shall have been fully exercised, the Company shall, within five (5) Business Days after receipt of the Exercise Delivery Documents at the
request of the holder, and at its own expense, issue a new Warrant identical in all respects to this Warrant exercised except it shall represent rights to purchase the number of Warrant Shares purchasable immediately prior to such exercise under
this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. Notwithstanding the foregoing, (i) execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the
same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares and (ii) execution and delivery of the Exercise Notice for all of the then remaining
Warrant Shares shall have the same effect as cancellation of the original Warrant after delivery of the Warrant Shares in accordance with the terms hereof. The holder and any assignee or transferee, by acceptance of this Warrant, acknowledge and
agree that, by reason of the provisions of this paragraph, following exercise of any portion of this Warrant, the then-remaining number of Warrant Shares issuable hereunder may be less than the number of Warrant Shares stated on the first page of
this Warrant. In no event shall the Company be liable to any assignee or transferee of this Warrant in the event the number of Warrant Shares to which such assignee or transferee claims it is entitled to hereunder exceeds the then-remaining number
of Warrant Shares represented by this Warrant. 
 (c) The Company shall not be required to issue fractions of shares of Common Stock upon
exercise of this Warrant or to distribute certificates evidencing such fractional shares. If more than one Warrant shall be presented for exercise in full at the same time by the same holder, the number of full shares of Common Stock shall be
issuable upon the exercise thereof shall be computed on the basis of the aggregate number of shares of Common Stock purchasable on exercise of all Warrants so presented. In lieu of any fractional shares, there shall be paid to the holder an amount
of cash equal to the same fraction of the current market value of a share of Common Stock. For purposes of this Section 2(c), the current market value of a share of Common Stock shall be the Trading Price of a share of Common Stock for the
Trading Day immediately prior to the date of such exercise. 
 (d) Cashless Exercise. Notwithstanding anything contained herein to the
contrary (other than Section 2(e)(i) below), the holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in
payment of the aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”): 
  

					
	 Net Number =
	 	 (A x B) - (A x C)
	  	
		 	B	  	

 For purposes of the foregoing formula: 
 A= the total number of shares with respect to which this Warrant is then being exercised. 
 B= the VWAP of the Common Stock for the five (5) Trading Day period immediately preceding the date of the Exercise Notice. 
 C= the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise. 
  

 6 

 e) Limitation on Beneficial Ownership.
Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable by the holder hereof to the extent (but only to the extent) that, if exercisable by the holder, the holder or any of its affiliates would
beneficially own in excess of 4.90% (the “Maximum Percentage”) of the outstanding shares of Common Stock. To the extent the above limitation applies, the determination of whether this Warrant shall be exercisable
(vis-a-vis other convertible, exercisable or exchangeable securities owned by the holder) and of which warrants shall be exercisable (as among all warrants owned by the holder) shall, subject to such Maximum Percentage limitation, be determined on
the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be). No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this
paragraph with respect to any subsequent determination of exercisability. For the purposes of this paragraph, beneficial ownership and all determinations and calculations (including, without limitation, with respect to calculations of
percentage ownership) shall be determined by the holder in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. The provisions of this paragraph shall be implemented in a manner otherwise than
in strict conformity with the terms of this paragraph to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum Percentage beneficial ownership limitation herein contained or to make changes
or supplements necessary or desirable to properly give effect to such Maximum Percentage limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant. The holders of Common Stock shall be third
party beneficiaries of this paragraph and the Company may not waive this paragraph without the consent of holders of a majority of its Common Stock. For purposes of this Warrant, in determining the number of outstanding shares of Common
Stock, the holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K or Form 10-KSB (as the case may be), Form 10-Q or Form 10-QSB (as the case may be), Current Report on
Form 8-K or other public filing with the SEC (as defined in the Subscription Agreement) (as the case may be), (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth
the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the holder, the Company shall within one (1) Business Day confirm orally and in writing to the holder the number of shares of
Common Stock then outstanding, including by virtue of any prior conversion or exercise of convertible or exercisable securities into Common Stock, including, without limitation, pursuant to this Warrant or securities issued pursuant to the
Subscription Agreement and the Other Agreements. By written notice to the Company, the holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.90% specified in such notice, provided that any such increase
will not be effective until the sixty-first (61st) day after such notice is delivered to the Company.

 Section 3. Date; Duration. The issue date of this Warrant is July     , 2007 (the “Warrant Date”).
This Warrant, in all events, shall be wholly void and of no effect at 5:00 pm Pacific Time on the Expiration Date. 
 Section 4. Taxes.

 (a) The Company shall pay any and all documentary, stamp, transfer and other similar taxes that may be payable with respect to the
issuance and delivery of Warrant Shares upon exercise of this Warrant. 
  

 7 

 (b) The issuance of certificates for shares of Common Stock upon the exercise of this Warrant shall be
made without charge to the holder of this Warrant for any issue tax in respect thereof; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and
delivery of any certificate in a name other than that of the holder hereof or any of its affiliates, and the Company shall not be required to issue or deliver such certificates or other securities unless and until the person or persons requesting
the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
 Section 5. Warrant Call. At any time after a registration statement covering all the Registrable Shares has been declared effective by the Securities and Exchange Commission in accordance with the
Registration Rights Agreement, dated as of July     , 2007, by and among the Company, the investors party thereto and the placement agents party thereto (as such agreement may be amended, supplemented and modified from
time to time, the “Registration Rights Agreement”), the Company, at its option, may on one occasion, upon written notice to the holder (the “Call Notice”), call up to one hundred percent (100%) of this Warrant
if the Common Stock of the Company trades at a price equal to or greater than two (2) times the initial Exercise Price on the Warrant Date (the “Trigger Price”) (as adjusted for stock splits, combinations and the like) for
twenty (20) consecutive Trading Days prior to the date the Company calls the Warrant. To be effective, the Call Notice must be given within ten (10) days after the aforementioned twenty (20) Trading Day period. The Call Notice shall
state the date on which exercise shall be required (the “Required Exercise Date”), which shall be no less than thirty (30) days after the date of such notice (or, if such date is not a Business Day, on the next succeeding
Business Day), provided that the Company shall not have the right to issue a Call Notice if the Equity Conditions are not satisfied on each day during the period commencing on the date of the Call Notice and ending on the Required Exercise Date and
any such Call Notice issued in violation of the foregoing shall be invalid and of no force or effect. The rights and privileges granted pursuant to this Warrant with respect to such Warrant Shares subject to a valid Call Notice shall terminate if
this Warrant is not exercised with respect to such Warrant Shares by the holder of such Warrant on or prior to the Required Exercise Date. In the event that this Warrant is not exercised by such holder on or prior to the Required Exercise Date with
respect to the Warrant Shares subject to a valid Call Notice, the portion of this Warrant subject to such valid Call Notice shall expire at 5:00 p.m. eastern time on the Required Exercise Date and the Company will remit to such holder $0.01 per
Warrant Share and a new Warrant certificate representing the number of Warrant Shares, if any, with respect to which this Warrant has not been exercised or subject to a valid Call Notice upon such holder tendering to the Company the expired Warrant
certificate. If the Company elects to issue a valid Call Notice with respect to any portion of this Warrant, then it must simultaneously take the same action in the same proportion with respect to all warrants originally issued to all Other
Investors. If the Company does not comply with the immediately preceding sentence, then the Call Notice issued by the Company shall be invalid and of no force or effect. 
 Section 6. Warrant Holder Not Deemed a Stockholder. Except as otherwise specifically provided herein, prior to the exercise of this Warrant represented hereby, the holder of this Warrant shall not be
entitled, as such, to any rights of a stockholder of the Company, including, 

  

 8 

 
without limitation, the right to vote or to consent to any action of the stockholders of the Company, to receive dividends or other distributions, to
exercise any preemptive right or to receive any notice of meetings of stockholders of the Company, and shall not be entitled to receive any notice of any proceedings of the Company. In addition, nothing contained in this Warrant shall be construed
as imposing any liabilities on such holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. 

Section 7. [Intentionally Omitted] 
 Section 8.
Ownership and Transfer. 
 The Company shall maintain at its principal executive offices or such other office or agency of the Company as it may designate
by notice to the holder hereof, a register for this Warrant (the “Warrant Register”), in which the Company shall record the name and address of the person in whose name this Warrant has been issued. Upon the transfer of this Warrant
in accordance with the provisions of Section 7 hereof, the Company shall record the name and address of such new holder(s) as well as the name and address of each transferee. The Company may treat the person in whose name this Warrant is
registered on the Warrant Register as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant. 
 Section 9. Adjustment of Exercise Price and Number of Shares Issuable Upon Exercise Upon Certain Corporate Events. 
 The Exercise Price and the number of Warrant Shares issuable upon the exercise are subject to adjustment from time to time upon the occurrence of the
events enumerated in this Section 9. 
 (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of
the outstanding Common Stock in shares of Common Stock, the Exercise Price in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall
be reduced by multiplying such Exercise Price by a fraction of which (i) the numerator shall be the number of shares of Common Stock outstanding at the close of business on the record date of this Warrant fixed for such determination and
(ii) the denominator shall be the sum of such number of shares of Common Stock referred to in (i) above plus the total number of shares constituting such dividend or other distribution. Such reduction in the Exercise Price shall become
effective immediately after the opening of business on the day following the record date. If any dividend or distribution of the type described in this Section 9(a) is declared but not so paid or made, the Exercise Price shall again be
adjusted to the Exercise Price that would otherwise then be in effect if such dividend or distribution had not been declared. 
 (b) In case
the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Exercise Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be
proportionately reduced, and conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Exercise Price in effect at 

  

 9 

 
the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or
increase, as applicable, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
 (c) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the
Company or evidences of its indebtedness or other property (including cash or assets or securities, but excluding (i) dividends or distributions to which Section 9(a) applies, (ii) any dividend or distribution paid exclusively in
cash, or (iii) any consideration distributed in connection with reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 10 of this Warrant applies (the foregoing
hereinafter in this Section 9(c) called the “Distributed Assets”)), the Exercise Price shall be reduced so that the same shall be equal to the price determined by multiplying the Exercise Price in effect immediately prior to
the close of business on the Record Date with respect to such distribution by a fraction of which (i) the numerator shall be the Current Market Price (as defined in Section 9(d) of this Warrant) on such date less the fair market value (as
determined in good faith by the Company’s Board of Directors, whose determination shall be conclusive and set forth in a board resolution) on such date of the portion of the Distributed Assets so distributed applicable to one share of Common
Stock (determined on the basis of the number of shares of Common Stock outstanding on the Record Date (as defined in Section 9(d) of this Warrant)), and (ii) the denominator shall be such Current Market Price, such reduction to become
effective immediately prior to the opening of business on the day following the Record Date. 
 Such reduction in the Exercise Price shall
become effective immediately prior to the opening of business on the day following the Record Date. However, in the event the then fair market value (as so determined) of the portion of the Distributed Assets so distributed applicable to one share
of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that the holder of this Warrant shall have the right to receive upon exercise of this
Warrant (or any portion thereof) the amount of Distributed Assets such holder would have received had such holder converted this Warrant (or portion thereof) immediately prior to such Record Date (without regard to any limitations on exercise
contained herein). In the event that such dividend or distribution is not so paid or made, the Exercise Price shall again be adjusted to be the Exercise Price which would then be in effect if such dividend or distribution had not been declared.

 If the Company’s Board of Directors determines the fair market value of any distribution for purposes of this Section 9(c) by
reference to the actual trading market for any securities comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in computing the
Current Market Price pursuant to Section 9(d) of this Warrant to the extent possible, unless a majority of the independent members of the Company’s Board of Directors determines in good faith that determining the fair market value during
the Reference Period would not be in the best interest of the holders. 
 With respect to any rights that may be issued or distributed
pursuant to any rights plan that the Company implements after the date of issuance of this Warrant (a “Rights Plan”), upon exercise of this Warrant into Common Stock, to the extent such Rights Plan is in effect upon 

  

 10 

 
such exercise, the holder of this Warrant will receive, in addition to the Common Stock, the rights described therein (whether or not the rights have
separated from the Common Stock prior to the time of exercise), subject to the limitations set forth in any such Rights Plan. In the event the holder receives such rights, there will be no adjustment to the Exercise Price or the number of shares
issuable upon exercise of this Warrant pursuant to this Section 9(c). In the event the holder does not or is not entitled to receive such rights upon exercise of this Warrant for any reason, then an adjustment shall be made to the Exercise
Price to the extent provided for in the other provisions of this Section 9(c). 
 For purposes of this Section 9(c) and
Section 9(a) of this Warrant, any dividend or distribution to which this Section 9(c) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock to which
Section 9(a) of this Warrant apply (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants immediately followed by (2) a
dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Exercise Price reduction required by Section 9(a) of this Warrant with respect to such dividend or distribution shall then be made, except
(A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” “Record Date fixed for such
determination” and “Record Date” within the meaning of Section 9(a) of this Warrant, and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of
business on the date fixed for such determination” within the meaning of Section 9(a) of this Warrant and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be
disregarded in connection with such dividend or distribution. 
 (d) For purposes of this Section 9, the following terms shall have the
meaning indicated: 
 (1) “Current Market Price” shall mean the closing price per share of Common Stock on the date
immediately prior to the date in question. 
 (2) “Record Date” shall mean, with respect to any dividend, distribution or
other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash,
securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
 (e) The Company may make such reductions in the Exercise Price, in addition to those required by Sections 9(a) or (b) of this Warrant, as the Board
of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as
such for income tax purposes. 
 (f) No adjustment in the Exercise Price shall be required under this Section 9 unless such adjustment
would require an increase or decrease of at least 1% in the Exercise Price; provided, however, that any adjustments which by reason of this Section 9(f) are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations 

  

 11 

 
under this Section 9 shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be.
No adjustment need be made for a change in the no par value of the Common Stock. 
 (g) Notice to Holders of Warrants Prior to Certain
Actions. In case: 
 (1) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an
adjustment in the Exercise Price pursuant to this Section 9; 
 (2) of any Fundamental Transaction; or 
 (3) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company, 
 the Company shall cause to be provided to the holder of this Warrant at such address appearing in the Warrant Register at least ten (10) days prior to the applicable record or effective date hereinafter
specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the date as of which the holders of shares of Common Stock of
record to be entitled to such dividend, distribution, rights or warrants are to be determined, or (y) the date on which such Fundamental Transaction, dissolution, liquidation or winding-up is expected to become effective, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such Fundamental Transaction, dissolution, liquidation or winding-up.
Failure to give such notice, or any defect therein, shall not affect the legality or validity of the proceedings or actions described in clauses (1) through (3) of this Section 9(g). In addition, whenever the Exercise Price is
adjusted as provided in this Section 9, the Company shall prepare a notice of such adjustment of the Exercise Price setting forth the adjusted Exercise Price and the date on which each adjustment becomes effective and shall mail such notice of
such adjustment of the Exercise Price to the holder of this Warrant at his last address in the Warrant Register within twenty (20) days following the effective date of such adjustment. Failure to deliver such notice or any defect therein shall
not effect the legality or validity of any such adjustment. 
 (h) In any case in which this Section 9 provides that an adjustment shall
become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to the holder of this Warrant exercised after such record date and before the occurrence of such event the
additional shares of Common Stock issuable upon such exercise by reason of the adjustment required by such event over and above the Common Stock issuable upon such exercise before giving effect to such adjustment and (ii) paying to such holder
any amount in cash in lieu of any fraction pursuant to Section 2(d) of this Warrant. 
 (i) Upon each adjustment of the Exercise
Price pursuant to this Section 9, this Warrant shall thereupon evidence the right to purchase that number of Warrant Shares (calculated to the nearest hundredth of a share) obtained by multiplying the number of Warrant Shares purchasable
immediately prior to such adjustment upon exercise of this Warrant by the Exercise Price in effect immediately prior to such adjustment and dividing the product so obtained by the Exercise Price in effect immediately after such adjustment. The
adjustment pursuant to this Section 9(i) to the number of Warrant Shares purchasable upon exercise of this Warrant shall be made each time an adjustment of the Exercise Price is made pursuant to this Section 9 (or would be made but for
Section 9 of this Warrant). 
  

 12 

 (j) Adjustment Upon Issuance of Shares of Common Stock. If and whenever on or after the date of
the Subscription Agreement, the Company issues or sells, or in accordance with this Section 9(j) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the
account of the Company), other than Excluded Securities (as defined in the Subscription Agreement), for a consideration per share (the “New Issuance Price”) less than a price (the “Applicable Price”) equal to the
Exercise Price in effect immediately prior to such issue or sale or deemed issuance or sale (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance, the Exercise Price then in effect shall be reduced to
an amount equal to the New Issuance Price. For purposes of determining the adjusted Exercise Price under this Section 9(j), the following shall be applicable: 
 (i) Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one
share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common
Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 9(j)(i), the “lowest price per share for
which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option” shall be equal to the sum of the lowest amounts
of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise of the Option and upon conversion, exercise or exchange of any Convertible Security
issuable upon exercise of such Option. Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock or of such Convertible Securities upon the exercise of such
Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities. 
 (ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon the
conversion, exercise or exchange thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible
Securities for such price per share. For the purposes of this Section 9(j)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof” shall be equal to the sum
of the lowest amounts of consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible
Security. Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or
sale of such Convertible Securities 

  

 13 

 
is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 9(j),
except as contemplated below, no further adjustment of the Exercise Price shall be made by reason of such issue or sale. 
 (iii) Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible
Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the Exercise Price in effect at the time of such increase or decrease
shall be adjusted to the Exercise Price which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion
rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 9(j)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or
decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of
the date of such increase or decrease. No adjustment pursuant to this Section 9(j) shall be made if such adjustment would result in an increase of the Exercise Price then in effect. 
 (iv) Calculation of Consideration Received. In case any Option is issued in
connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been
issued for a consideration of $0.01. If any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the gross amount
received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such
consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company for each such security will be the VWAP of such security for the five (5) Trading Day Period immediately
preceding the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of
consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be. The fair
value of any consideration other than cash or securities will be determined jointly by the Company and the holder. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the
“Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth (10th) day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the holder. The determination of such appraiser shall be final and binding upon all
parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company. 
  

 14 

 (v) Record Date. If the Company takes a record of the holders of shares of Common
Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares of Common Stock, Options or
Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the
date of the granting of such right of subscription or purchase (as the case may be). 
 (vi) Number of Warrant Shares.
Simultaneously with any adjustment to the Exercise Price pursuant to this Section 9(j), unless waived in writing by the holder with respect to a particular adjustment, the number of Warrant Shares that may be purchased upon exercise of this
Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately
prior to such adjustment (without regard to any limitations on exercise contained herein). 
 (vii) Floor Price. No
adjustment pursuant to Section 9(j) shall cause the Exercise Price to be less than $7.00, as adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction. 
 (k) Other Events. In the event that the Company (or any direct or indirect subsidiary thereof) shall take any action to which the provisions
hereof are not strictly applicable, or, if applicable, would not operate to protect the holder from dilution or if any event occurs of the type contemplated by the provisions of this Section 9 but not expressly provided for by such provisions
(including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of Directors shall in good faith determine and implement an appropriate adjustment
in the Exercise Price and the number of Warrant Shares (if applicable) so as to protect the rights of the holder; provided that no such adjustment pursuant to this Section 9(k) will increase the Exercise Price or decrease the number of Warrant
Shares as otherwise determined pursuant to this Section 9(k), provided further that if the holder does not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Company’s Board of
Directors and the holder shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding and whose fees and expenses shall be
borne by the Company. 
 Section 10. Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events occur, namely
(i) any reclassification, reorganization, recapitalization or other change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a
subdivision or combination), (ii) any consolidation, merger, statutory share exchange or combination of the Company with or into another Person (whether or not the Company is the surviving corporation) (other than as a result of a change in
name, a change in par value or a change in the jurisdiction of incorporation, the sole purpose of which is a change in domicile), (iii) any sale, assignment, transfer, conveyance or other disposition of the properties and assets of the Company
as, or substantially as, an entirety to any other Person, (iv) another Person is allowed to make a purchase, tender or exchange offer that is accepted by the holders of more than the 50% of the 

  

 15 

 
outstanding shares of Common Stock (not including any shares of Common Stock held by the Person or Persons making or party to, or associated or affiliated
with the Persons making or party to, such purchase, tender or exchange offer), (v) a stock purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement)
in consummated with another Person whereby such other Person acquires more than the 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated
or affiliated with the other Persons making or party to, such stock purchase agreement or other business combination) or (vi) any “person” or “group” (as these terms are used for purposes of Sections 13(d) and 14(d) of the
Exchange Act) is or shall become the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% of the aggregate ordinary voting power represented by issued and outstanding Common Stock (each of
the foregoing events in clauses (i) through (vi) being a “Fundamental Transaction”), then the Company or the Successor Entity, as the case may be, shall issue a replacement Warrant providing that this Warrant shall be
exercisable for the kind and amount of shares of stock and other securities or property or assets (including cash) receivable upon such Fundamental Transaction by a holder (an “Assumed Holder”) of a number of shares of Common Stock
issuable upon exercise of this Warrant immediately prior to such Fundamental Transaction (assuming, for such purposes, a sufficient number of authorized shares of Common Stock available for issuance upon exercise of all such Warrants and
disregarding all limitations on exercise contained herein). For purposes of determining what would be receivable by such Assumed Holder in such Fundamental Transaction in respect of such number of shares of Common Stock if such Fundamental
Transaction provided election rights to holders of Common Stock as to the consideration to be received by them, then (i) such Assumed Holder will be deemed to have exercised election rights in the same proportion as the
holder of this Warrant exercised any election rights with respect to the shares of Common Stock actually owned by the holder and entitling the holder to so exercise election rights, and (ii) if the holder of this Warrant did
not actually own shares of Common Stock so that the holder was not entitled to exercise any such election rights, then such Assumed Holder will be deemed not to have exercised any election, and if the kind or amount of securities,
cash or other property receivable upon such Fundamental Transaction is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised, then the form and type of consideration to be receivable by
such Assumed Holder shall be deemed to be the kind and amount of securities, cash or other property receivable upon such Fundamental Transaction so receivable by a plurality of the non-electing shares. Notwithstanding anything to the contrary
in this Section 10, the holder hereof, and of such replacement Warrant, shall continue to be entitled to the benefit of the Maximum Percentage, applied however with respect to shares of capital stock registered under the Exchange Act and
thereafter receivable upon exercise of this Warrant (or any such other warrant or replacement Warrant. Such replacement Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for
in Section 9 of this Warrant. If, in the case of any such Fundamental Transaction, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock shall include shares of stock or other securities and assets
of a Person other than the Successor Entity in such Fundamental Transaction, then such replacement Warrant shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the holder of this
Warrant as shall be deemed reasonably necessary by the holder. The Exercise Price for the stock and other securities, property and assets (including cash) so receivable upon such event shall be an amount equal to the Exercise Price immediately prior
to such event. 
  

 16 

 The Company shall mail such replacement Warrant to the holder of this Warrant, at such holder’s
address appearing in the Warrant Register within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such replacement Warrant. Upon the occurrence of any Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer
instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity
had been named as the Company herein. 
 The above provisions of this Section 10 shall similarly apply to successive or series of
related Fundamental Transactions. 
 If this Section 10 applies to any event or occurrence, Section 9 of this Warrant shall not
apply, provided that such other provisions shall continue to apply to all other issuances. 
 Section 11. Lost, Stolen, Mutilated or Destroyed
Warrants. If this Warrant is lost, stolen, mutilated or destroyed, the Company shall promptly, on receipt of an indemnification undertaking reasonably acceptable to the Company (but not including a surety bond) (or in the case of a mutilated
Warrant, the Warrant), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed. 
 Section 12.
Reservation of Common Stock. The Company hereby represents and warrants that there have been reserved, and the Company shall at all applicable times keep reserved until issued (if necessary) as contemplated by this Section 12, out of the
authorized and unissued shares of Common Stock, sufficient shares to provide for the exercise of the rights of purchase represented by this Warrant. If, notwithstanding the foregoing, and not in limitation thereof, at any time while this Warrant is
outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant at least a number of shares of Common Stock equal to the
maximum number of shares of Common Stock as shall from time to time be necessary to effect the exercise of all of this Warrant (the “Required Reserve Amount”) (an “Authorized Share Failure”), then the Company shall
immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for all of this Warrant then outstanding. Without limiting the
generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall
hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts
to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. The Company agrees that all Warrant Shares issued
upon exercise of the Warrant shall be, at the time of delivery of the certificates for such Warrant Shares upon the due exercise of this Warrant, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company.

  

 17 

 Section 13. Benefits. Except as expressly set forth in Section 2(e), nothing in this Warrant shall be
construed to give any person, firm or corporation (other than the Company and the holder of this Warrant) any legal or equitable right, remedy or claim, it being agreed that this Warrant shall be for the sole and exclusive benefit of the Company and
the holder of this Warrant. 
 Section 14. Notice. All notices, requests, consents and other communications hereunder shall be in writing, shall
be delivered (A) if within United States by first-class registered or certified airmail, or nationally recognized overnight express courier (with next day delivery specified), postage prepaid, or by facsimile, or (B) if delivered from

recognized overnight carrier, one business day after so mailed, (iii) if delivered by International Federal Express, two business days after so mailed, and (iv) if delivered by facsimile, upon electric confirmation of receipt, and shall be

 Section 15. Amendments. This Warrant and any term hereof may be amended, changed,
waived, discharged, or terminated only by an instrument in writing signed by the Company and 

  

 18 

 
the holders of this Warrant. Such amendment, change, waiver, discharge or termination shall be binding on the Company and all of the Warrant holder’s
assignees and transferees. No waivers of any term, condition or provision of this Warrant in any one or more instances shall be deemed to be or construed as a further or continuing waiver of any such term, condition or provision. If any warrant
issued pursuant to any Other Agreement is amended or modified by the Company and any Other Investor, then the holder may, in its sole discretion, choose to have such amendment or modification apply to this Warrant by delivering written notice to the
Company. 
 Section 16. Obligations Binding on Successors. This Warrant will be binding upon any entity succeeding to the Company in one or a
series of transactions by merger, consolidation or acquisition of all or substantially all of the Company’s assets or other similar transactions. 
 Section 17. Governing Law. This Warrant shall be governed by and construed in accordance with the laws of the State of New York.

 Section 19. Remedies. The remedies provided in this
Warrant shall be cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein
shall limit the right of the holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the holder
and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to
an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. The issuance of shares and certificates for shares as contemplated hereby upon the exercise of this Warrant
shall be made without charge to the holder or such shares for any issuance tax or other costs in respect thereof, provided that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any certificate in a name other than the holder or its agent on its behalf. 
 Section 20. Noncircumvention. The Company hereby
covenants and agrees that the Company will not, by amendment of its Articles of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any
other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the
rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect,
(ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as
this Warrant is outstanding, take all action necessary to reserve and keep available out of its authorized and 

  

 19 

 
unissued shares of Common Stock, solely for the purpose of effecting the exercise of this Warrant, the maximum number of shares of Common Stock as shall from
time to time be necessary to effect the exercise of this Warrant (without regard to any limitations on exercise contained herein).
