On or prior to the Filing Deadline, the Company shall prepare and file with the Commission a Registration Statement covering the resale of all of the Registrable Securities not already covered by an existing and effective Registration Statement for
an offering to be made on a continuous basis pursuant to Rule 415, or if Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of Registrable Securities as the Holders may reasonably
specify (the “Initial Registration Statement”). The Initial Registration Statement shall be on Form S-3 (except if the Company is ineligible to register for resale the Registrable Securities on Form S-3, in which case such
registration shall be on another appropriate form in accordance with Section 2(e)) and shall contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement)
the “Plan of Distribution” section substantially in the form attached hereto as Annex A. Notwithstanding the registration obligations set forth in this Section 2, in the event the Commission informs the Company that all
of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the holders thereof,
(ii) use its best efforts to file amendments to the Initial Registration Statement as required by the Commission and/or (iii) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration
Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the Commission, on Form S-3 or such other form available to register for resale the Registrable Securities as a secondary
offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its reasonable best efforts to advocate with the Commission for the registration of all of the Registrable
Securities in accordance with the SEC Guidance, including without limitation, the Manual of Publicly Available Telephone Interpretations D.29. In the event the Company amends the Initial Registration Statement or files a New Registration Statement,
as the case may be, under clauses (ii) or (iii) above, the Company will use its reasonable best efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of
securities in general, one or more registration statements on Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, or the New
Registration Statement (the “Remainder Registration Statements”). 
 (b) The Company shall use its reasonable
best efforts to cause each Registration Statement to be declared effective by the Commission as soon as practicable and, with respect to the Initial Registration Statement or the New Registration Statement, as applicable, no later than the
Effectiveness Deadline (including filing with the Commission a request for acceleration of effectiveness in accordance with Rule 461 promulgated under the Securities Act within five (5) Business Days after the date that the Company is notified
(orally or in writing, whichever is earlier) by the Commission that such Registration Statement will not be “reviewed,” or not be subject to further review and the effectiveness of such Registration Statement may be accelerated), and shall
use its reasonable best efforts to keep such Registration Statement continuously effective under the Securities Act until the earlier of (i) such time as 

  

 4 








 
all of the Registrable Securities covered by such Registration Statement have been publicly sold by the Holders or (ii) the date that all Registrable
Securities covered by such Registration Statement may be sold by non-affiliates without volume restrictions pursuant to Rule 144(k) (the “Effectiveness Period”). The Company shall request effectiveness of a Registration Statement as
of 5:00 p.m. New York City time on a Trading Day. The Company shall promptly notify the Holders via facsimile or electronic mail of a “.pdf” format data file of the effectiveness of a Registration Statement on or before one Trading Day
after the day the Company telephonically confirms effectiveness with the Commission, which confirmation shall be the date requested for effectiveness of a Registration Statement. The Company shall, by 9:30 a.m. New York City Time on the second
Trading Day after the Effective Date, file a final Prospectus with the Commission, as required by Rule 424(b). Notwithstanding any other provision of this Agreement and subject to the payment of liquidated damages in Section 2(c), if any SEC
Guidance sets forth a limitation of the number of Registrable Securities permitted to be registered on a particular Registration Statement (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the
registration of all or a greater number of Registrable Securities), the inclusion of the Shares in such Registration Statement shall take precedence over and shall not be cut back until the following securities of the Company are cut back and
removed from such Registration Statement (in the following order): (i) any securities of the Company to be included in such Registration Statement pursuant to Section 6(b) (by reference to Schedule 3.1(y) to the Purchase Agreement),
(ii) Warrant Shares (other than those Warrant Shares referred to in clause (ii)) and (iii) Shares. Any required cutbacks of Shares or Warrant Shares shall be applied to the Purchasers pro-rata in accordance with the number of such Shares
or Warrant Shares sought to be included in such Registration Statement by reference to such Purchaser’s (and in the case of a subsequent transfer the initial Purchaser’s) aggregate Subscription Amount (as defined in the Purchase Agreement)
relative to all Subscription Amounts. 
 (c) If: (i) the Initial Registration Statement is not filed with the Commission
on or prior to the Filing Deadline, (ii) the Initial Registration Statement or the New Registration Statement, as applicable, is not declared effective by the Commission (or otherwise does not become effective) for any reason on or prior to the
Effectiveness Deadline or (iii) after its Effective Date, (A) such Registration Statement ceases for any reason (including without limitation by reason of a stop order, or the Company’s failure to update the Registration Statement),
to remain continuously effective as to all Registrable Securities for which it is required to be effective or (B) the Holders are not permitted to utilize the Prospectus therein to resell such Registrable Securities, in the case of (A) and
(B), for more than an aggregate of 30 Trading Days (which need not be consecutive) (other than during an Allowable Grace Period (as defined in Section 2(e) of this Agreement)) or (iv) a Grace Period (as defined in Section 2(e) of this
Agreement) exceeds the length of an Allowable Grace Period (any such failure or breach in clauses (i) through (iv) above being referred to as an “Event,” and, for purposes of clauses (i) or (ii), the date on which such Event
occurs, or for purposes of clause (iii), the date on which such 30 Trading Day period is exceeded, or for purposes of clause (iv) the date on which such Allowable Grace Period is exceeded, being referred to as an “Event Date”),
then in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the
applicable Event is cured, the Company shall pay to each Holder an amount in cash, as partial liquidated damages and not as a penalty (“Liquidated Damages”), equal to 1.0% of the aggregate purchase price paid by such Holder pursuant
to the Purchase Agreement for any Registrable Securities then held by such Holder. The parties agree that (1) the Company will not be liable for Liquidated Damages under this Agreement with respect to any Warrants or Warrant Shares, (2) in
no event shall the Company be liable in any 30-day period for Liquidated Damages under this Agreement in excess of 1.0% of the aggregate purchase price paid by the Holders pursuant to the Purchase Agreement and (3) the maximum aggregate
Liquidated Damages payable to a Holder under this Agreement shall be ten percent (10%) of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement. If the Company fails to pay any Liquidated Damages pursuant to this
Section in full within five (5) Business Days after the date payable, the 

  

 5 








 
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 the
Holder, accruing daily from the date such Liquidated Damages are due until such amounts, plus all such interest thereon, are paid in full. The Liquidated Damages pursuant to the terms hereof shall apply on a daily pro-rata basis for any portion of a
month prior to the cure of an Event, except in the case of the first Event Date. Notwithstanding the above, the Company shall not be liable for liquidated damages under this Agreement as to any Registrable Securities which are not permitted by the
Commission to be included in a Registration Statement due solely to SEC Guidance from the time that it is determined that such Registrable Securities are not permitted to be registered solely due to SEC Guidance until such time as the provisions of
this Agreement as to the Remainder Registration Statements required to be filed hereunder are triggered, in which case the provisions of this Section 2(c) shall once again apply, if applicable. In such case, the liquidated damages shall be
calculated to only apply to the percentage of Registrable Securities which are permitted in accordance with SEC Guidance to be included in such Registration Statement. The Effectiveness Deadline for a Registration Statement shall be extended without
default or Liquidated Damages hereunder in the event that the Company’s failure to obtain the effectiveness of the Registration Statement on a timely basis results solely from the failure of a Purchaser to timely provide the Company with
information requested by the Company and necessary to complete the Registration Statement in accordance with the requirements of the Securities Act (in which the Effectiveness Deadline would be extended with respect to Registrable Securities held by
such Purchaser). 
 (d) Each Holder agrees to furnish to the Company a completed Selling Stockholder Questionnaire not more
than five (5) Trading Days following the date of this Agreement. Each Holder further agrees that it shall not be entitled to be named as a selling security holder in the Registration Statement or use the Prospectus for offers and resales of
Registrable Securities at any time, unless such Holder has returned to the Company a completed and signed Selling Stockholder Questionnaire. If a Holder of Registrable Securities returns a Selling Stockholder Questionnaire after the deadline
specified in the previous sentence, the Company shall use its commercially reasonable efforts to take such actions as are required to name such Holder as a selling security holder in the Registration Statement or any pre-effective or post-effective
amendment thereto and to include (to the extent not theretofore included) in the Registration Statement the Registrable Securities identified in such late Selling Stockholder Questionnaire. Each Holder acknowledges and agrees that the information in
the Selling Stockholder Questionnaire will be used by the Company in the preparation of the Registration Statement and hereby consents to the inclusion of such information in the Registration Statement. 
 (e) Notwithstanding anything to the contrary herein, at any time after the Registration Statement has been declared effective by the
Commission, the Company may delay the disclosure of material non-public information concerning the Company if the disclosure of such information at the time is not, in the good faith judgment of the Company, in the best interests of the Company (a
“Grace Period”); provided, however, the Company shall promptly (i) notify the Holders in writing of the existence of material non-public information giving rise to a Grace Period (provided that the Company shall not
disclose the content of such material non-public information to the Holders) or the need to file a post-effective amendment, as applicable, and the date on which such Grace Period will begin, and (ii) notify the Holders in writing of the date
on which the Grace Period ends; provided, further, that no single Grace Period shall exceed thirty (30) consecutive days, and during any three hundred sixty-five (365) day period, the aggregate of all Grace Periods shall not exceed
an aggregate of sixty (60) days (each Grace Period complying with this provision being an “Allowable Grace Period”). For purposes of determining the length of a Grace Period, the Grace Period shall be deemed to begin on and
include the date the Holders receive the notice referred to in clause (i) above and shall end on and include the later of the date the Holders receive the notice referred to in clause (ii) above and the date referred to in such notice;
provided, however, that no Grace Period shall be longer than an Allowable Grace Period. Notwithstanding anything to the contrary, the Company shall cause the Transfer Agent to deliver 

  

 6 








 
unlegended shares of Common Stock to a transferee of a Holder in accordance with the terms of the Purchase Agreement in connection with any sale of
Registrable Securities with respect to which a Holder has entered into a contract for sale prior to the Holder’s receipt of the notice of a Grace Period and for which the Holder has not yet settled. 
 (f) In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall
(i) register the resale of the Registrable Securities on another appropriate form and (ii) undertake to register the Registrable Securities on Form S-3 promptly after such form is available, provided that the Company shall maintain
the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the Commission. 
 3. Registration Procedures 
 In connection with the Company’s registration obligations hereunder, the Company shall: 
 (a) Not less than
five Trading Days prior to the filing of a Registration Statement and not less than one Trading Day prior to the filing of any related Prospectus or any amendment or supplement thereto (except for Annual Reports on Form 10-K, and Quarterly Reports
on Form 10-Q and Current Reports on Form 8-K and any similar or successor reports), the Company shall furnish to the Holder copies of such Registration Statement, Prospectus or amendment or supplement thereto, as proposed to be filed, which
documents will be subject to the review of such Holder (it being acknowledged and agreed that if a Holder does not object to or comment on the aforementioned documents within such five Trading Day or one Trading Day period, as the case may be, then
the Holder shall be deemed to have consented to and approved the use of such documents). The Company shall not file any Registration Statement or amendment or supplement thereto in a form to which a Holder reasonably objects in good faith, provided
that, the Company is notified of such objection in writing within the five (5) Trading Day or one (1) Trading Day period described above, as applicable. 
 (b) (i) Prepare and file with the Commission such amendments (including post-effective amendments) and supplements, to each Registration
Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective as to the applicable Registrable Securities for its Effectiveness Period (except during an Allowable Grace
Period); (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented or amended, to be filed pursuant to Rule 424 (except during an
Allowable Grace Period); (iii) respond as promptly as reasonably practicable to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and, as promptly as reasonably possible, provide the
Holders true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that pertains to the Holders as “Selling Stockholders” but not any comments that would result in the disclosure to
the Holders of material and non-public information concerning the Company; and (iv) comply with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration
Statement until such time as all of such Registrable Securities shall have been disposed of (subject to the terms of this Agreement) in accordance with the intended methods of disposition by the Holders thereof set forth in such Registration
Statement as so amended or in such Prospectus as so supplemented; provided, however, that each Purchaser shall be responsible for the delivery of the Prospectus to the Persons to whom such Purchaser sells any of the Shares or the Warrant
Shares (including in accordance with Rule 172 under the Securities Act), and each Purchaser agrees to dispose of Registrable Securities in compliance with the Plan of Distribution described in the Registration Statement and otherwise in compliance
with applicable federal and state securities laws. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this 

  

 7 








 
Agreement (including pursuant to this Section 3(b)) by reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report
under the Exchange Act, the Company shall have incorporated such report by reference into such Registration Statement, if applicable, or shall file such amendments or supplements with the Commission on the same day on which the Exchange Act report
which created the requirement for the Company to amend or supplement such Registration Statement was filed. 
 (c) Notify the
Holders (which notice shall, pursuant to clauses (iii) through (v) hereof, be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably practicable (and, in the
case of (i)(A) below, not less than two Trading Days prior to such filing, in the case of (iii) and (iv) below, not more than one Trading Day after such issuance or receipt, in the case of (v) below, not less than one Trading Day
after a determination by the Company that the financial statements in any Registration Statement have become ineligible for inclusion therein and, in the case of (v) below, not more than one Trading Day after the occurrence or existence of such
development) and (if requested by any such Person) confirm such notice in writing no later than one Trading Day following the day (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement is
proposed to be filed; (B) when the Commission notifies the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on any Registration Statement (in which case the
Company shall provide to the Holder true and complete copies of all comments that pertain to the Holders as a “Selling Stockholder” or if it would materially impact the Holder, to the “Plan of Distribution” and all written
responses thereto, but not information that the Company believes would constitute material and non-public information); and (C) with respect to each Registration Statement or any post-effective amendment, when the same has become effective;
(ii) of any request by the Commission or any other Federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information that pertains to the Holders as “Selling
Stockholders” or if it would materially impact the Holder, the “Plan of Distribution”; (iii) of the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of
a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or
exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (v) of the occurrence of any event or passage of time that makes the
financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in
any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which they
were made), not misleading. 
 (d) Use commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the
withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at soon
as practicable. 
 (e) If requested by a Holder, furnish to such Holder, without charge, at least one conformed copy of each
Registration Statement and each amendment thereto and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission;
provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system. 
  

 8 








 (f) Prior to any resale of Registrable Securities by a Holder, use its commercially
reasonable efforts to register or qualify or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the registration or qualification) of such Registrable Securities for the resale by the Holder
under the securities or Blue Sky laws of such jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to
do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that the Company shall not be required to qualify
generally to do business in any jurisdiction where it is not then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such
jurisdiction. 
 (g) If requested by the Holders, cooperate with the Holders to facilitate the timely preparation and delivery
of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by the Purchase Agreement and under law, of all restrictive legends,
and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may reasonably request. 
 (h) Following the occurrence of any event contemplated by Section 3(c)(iii)-(v), as promptly as reasonably practicable under the circumstances taking into account the Company’s good faith assessment
of any adverse consequences to the Company and its stockholders of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to the affected Registration Statements or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain an untrue statement
of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which they
were made), not misleading. 
 (i) Comply with all applicable rules and regulations of the Commission. 
 (j) The Company may require each selling Holder to furnish to the Company a certified statement as to the number of shares of Common Stock
beneficially owned by such Holder and, if required by the Commission, the natural persons thereof that have voting and dispositive control over the Shares. During any periods that the Company is unable to meet its obligations hereunder with respect
to the registration of the Registrable Securities solely because any Holder fails to furnish such information within three Trading Days of the Company’s request, any liquidated damages that are accruing at such time as to such Holder only shall
be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the Company. 
 4. Registration Expenses. All fees and expenses incident to the Company’s performance of or compliance with its obligations under this
Agreement (excluding any underwriting discounts and selling commissions and all legal fees and expenses of legal counsel for any Holder) shall be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration
Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be
made with any Trading Market on which the Common Stock is then listed for trading and (B) with respect to compliance with applicable state securities or Blue Sky laws (including, without limitation, fees 

  

 9 








 
and disbursements of counsel for the Company in connection with Blue Sky qualifications or exemptions of the Registrable Securities and determination of the
eligibility of the Registrable Securities for investment under the laws of such jurisdictions as requested by the Holders), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities and
of printing prospectuses if the printing of prospectuses is reasonably requested by the Holders of a majority of the Registrable Securities included in the Registration Statement), (iii) messenger, telephone and delivery expenses,
(iv) fees and disbursements of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in connection with the
consummation of the transactions contemplated by this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement
(including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder. In no event shall the Company be responsible for any underwriting, broker or similar fees or commissions of any Holder or, except to the extent provided for in the Transaction Documents,
any legal fees or other costs of the Holders. 
 5. Indemnification. 
 (a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and
hold harmless each Holder, the officers, directors, agents, partners, members, managers, stockholders, Affiliates and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act) and the officers, directors, partners, members, managers, stockholders, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all
losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of
or are based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or
arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in light of
the circumstances under which they were made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the
performance of its obligations under this Agreement, except to the extent, but only to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding such
Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and
approved by such Holder expressly for use in a Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto (it being understood that the Holder has approved Annex A hereto for this purpose),
(B) in the case of an occurrence of an event of the type specified in Section 3(c)(iii)-(v), related to the use by a Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the
Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated and defined in Section 6(e) below, but only if and to the extent that following the receipt of the Advice the misstatement or omission
giving rise to such Loss would have been corrected or (C) any such Losses arise out of the Purchaser’s (or any other indemnified Person’s) failure to send or give a copy of the Prospectus or supplement (as then amended or
supplemented) to the Persons asserting an untrue statement or alleged untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such Person if such
statement or omission was corrected in such Prospectus or supplement. 

  

 10 








 
The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding arising from or in connection with the transactions
contemplated by this Agreement of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an Indemnified Party (as defined in Section 5(c)) and shall
survive the transfer of the Registrable Securities by the Holders. 
 (b) Indemnification by Holders. Each Holder
shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the
Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based upon (x) such Holder’s
failure to comply with the prospectus delivery requirements of the Securities Act or (y) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any
Prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading (i) to the extent, but only to the extent, that such untrue statements or omissions are based solely upon
information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein or (ii) to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of
Registrable Securities and was reviewed and approved by such Holder expressly for use in a Registration Statement (it being understood that the Holder has approved Annex A hereto for this purpose), such Prospectus or such form of Prospectus
or in any amendment or supplement thereto or (iii) in the case of an occurrence of an event of the type specified in Section 3(c)(iii)-(v), to the extent related to the use by such Holder of an outdated or defective Prospectus after
the Company has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 6(e). In no event shall the liability of any selling Holder
hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. 
 (c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity
hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to
assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all reasonable fees and expenses incurred in connection with defense thereof; provided, that the failure of
any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction
(which determination is not subject to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party. 
 An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified
Party shall have been advised by counsel that a conflict of interest exists if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing
that it elects to employ separate counsel at the expense of the Indemnifying 

  

 11 








 
Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party);
provided, that the Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such
Proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending
Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding. 
 Subject to the terms of this Agreement, all fees and expenses of the Indemnified Party (including reasonable fees and expenses to the
extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within twenty Trading Days of written notice thereof to the
Indemnifying Party; provided, that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses applicable to such actions for which such Indemnified Party is finally judicially determined
to not be entitled to indemnification hereunder). The failure to deliver written notice to the Indemnifying Party within a reasonable time of the commencement of any such action shall not relieve such Indemnifying Party of any liability to the
Indemnified Party under this Section 5, except to the extent that the Indemnifying Party is materially and adversely prejudiced in its ability to defend such action. 
 (d) Contribution. If the indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient to
hold an Indemnified Party harmless for any Losses, then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion
as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative
fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a
material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action,
statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other reasonable fees or expenses incurred
by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. 

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by
pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5(d), no Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall
be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 
  

 12 








 The indemnity and contribution agreements contained in this Section are in addition to
any liability that the Indemnifying Parties may have to the Indemnified Parties and are not in dimunition or limitation of the indemnification provisions under the Purchase Agreement. 
 6. Miscellaneous. 
 (a) Remedies. In the event of a breach by the Company or by a Holder of any of their obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not provide adequate compensation for any losses
incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be
adequate. 
 (b) No Piggyback on Registrations. Except and to the extent specified in Schedule 3.1(y) to the
Purchase Agreement, neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in a Registration Statement other than the Registrable Securities and the Company
shall not prior to the Effective Date enter into any agreement providing any such right to any of its security holders. The Company shall not, from the date hereof until the date that is 60 days after the Effective Date of the Registration
Statement, prepare and file with the Commission a registration statement relating to an offering for its own account under the Securities Act of any of its equity securities other than a registration statement on Form S-8 or, in connection with an
acquisition, on Form S-4. For the avoidance of doubt, the Company shall not be prohibited from preparing and filing with the Commission a registration statement relating to an offering of Common Stock by existing stockholders of the Company under
the Securities Act pursuant to the terms of registration rights held by such stockholder or from filing amendments to registration statements filed prior to the date of this Agreement. 
 (c) Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities
Act as applicable to it in connection with sales of Registrable Securities pursuant to a Registration Statement and shall sell the Registrable Securities only in accordance with a method of distribution described in the Registration Statement

 (d) Discontinued Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon receipt of
a notice from the Company of the occurrence of any event of the kind described in Section 3(c)(iii)-(v), such Holder will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until it is advised
in writing (the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company may provide appropriate stop orders to enforce the provisions of this
paragraph. 
 (e) No Inconsistent Agreements. Neither the Company nor any of its Subsidiaries has entered, as of the
date hereof, nor shall the company or any of its Subsidiaries, on or after the date hereof, enter into any agreement with respect to its securities, that would have the effect of impairing the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. 
 (f) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or supplemented, or waived unless the same shall be in writing and signed by the Company and Holders holding a majority of the then outstanding Registrable Securities.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders and that does not directly 

  

 13 








 
or indirectly affect the rights of other Holders may be given by Holders of all of the Registrable Securities to which such waiver or consent relates;
provided, however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. 
 (g) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be
delivered as set forth in the Purchase Agreement. 
 (h) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and permitted assigns of each of the parties and shall inure to the benefit of each Holder. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. The Company may not assign its rights (except by merger or in
connection with another entity acquiring all or substantially all of the Company’s assets) or obligations hereunder without the prior written consent of all the Holders of the then outstanding Registrable Securities. Each Holder may assign its
respective rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement; provided in each case that (i) the Holder agrees in writing with the transferee or assignee to assign such rights and related obligations
under this Agreement, and for the transferee or assignee to assume such obligations, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (ii) the Company is, within a reasonable time after
such transfer or assignment, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being transferred or assigned, (iii) at or before the time
the Company received the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein and (iv) the transferee is an
“accredited investor,” as that term is defined in Rule 501 of Regulation D. 
 (i) Execution and
Counterparts. This Agreement may be executed in two or more counterparts, each of which when so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement and shall become effective
when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery
of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf”
signature were the original thereof. 
 (j) Governing Law. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be determined in accordance with the provisions of the Purchase Agreement. 
 (k) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any other remedies provided by law. 
 (l) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their good faith reasonable efforts to find and employ an
alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 
  

 14 








 (m) Headings. The headings in this Agreement are for convenience only and shall
not limit or otherwise affect the meaning hereof. 
 (n) Independent Nature of Purchasers’ Obligations and Rights.
The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser hereunder, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser
hereunder. The decision of each Purchaser to purchase the Shares and Warrants pursuant to the Transaction Documents has been made independently of any other Purchaser. Nothing contained herein or in any other agreement or document delivered at any
closing, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in
any way acting in concert with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment
hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Shares and Warrants or enforcing its rights under the Transaction Documents. Each Purchaser shall be entitled to protect
and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. The Company acknowledges
that each of the Purchasers has been provided with the same Registration Rights Agreement for the purpose of closing a transaction with multiple Purchasers and not because it was required or requested to do so by any Purchaser.

 Annex A 
 PLAN OF DISTRIBUTION 
 We are registering the shares of Common Stock issued to the selling
stockholders and issuable upon exercise of the warrants issued to the selling stockholders to permit the resale of these shares of Common Stock by the holders of the shares of Common Stock and warrants from time to time after the date of this
prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of Common Stock. We will bear all fees and expenses incident to our obligation to register the shares of Common Stock. 
 The selling stockholders may sell all or a portion of the shares of Common Stock beneficially owned by them and offered hereby from time to time directly
or through one or more underwriters, broker-dealers or agents. If the shares of Common Stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s
commissions. The shares of Common Stock may be sold on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, in the over-the-counter market or in transactions otherwise than on
these exchanges or systems or in the over-the-counter market and in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales
may be effected in transactions, which may involve crosses or block transactions. The selling stockholders may use any one or more of the following methods when selling shares: 
  

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


  

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


  

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


  

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


  

	 	•	 	 privately negotiated transactions; 


  

	 	•	 	 settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part; 


  

	 	•	 	 broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share; 


  

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



  

	 	•	 	 a combination of any such methods of sale; and 


  

	 	•	 	 any other method permitted pursuant to applicable law. 


 The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, as permitted by that rule, or Section 4(1) under the
Securities Act, if available, rather than under this prospectus, provided that they meet the criteria and conform to the requirements of those provisions. 







 Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in
sales. If the selling stockholders effect such transactions by selling shares of Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts,
concessions or commissions from the selling stockholders or commissions from purchasers of the shares of Common Stock for whom they may act as agent or to whom they may sell as principal. Such commissions will be in amounts to be negotiated, but,
except as set forth in a supplement to this Prospectus, in the case of an agency transaction will not be in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or
markdown in compliance with FINRA IM-2440. 
 In connection with sales of the shares of Common Stock or otherwise, the selling stockholders
may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The selling stockholders may also sell
shares of Common Stock short and if such short sale shall take place after the date that this Registration Statement is declared effective by the Commission, the selling stockholders may deliver shares of Common Stock covered by this prospectus to
close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares, to the extent permitted by
applicable law. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or
other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). Notwithstanding the
foregoing, the selling stockholders have been advised that they may not use shares registered on this registration statement to cover short sales of our common stock made prior to the date the registration statement, of which this prospectus forms a
part, has been declared effective by the SEC. 
 The selling stockholders may, from time to time, pledge or grant a security interest in some
or all of the warrants or shares of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock from time to time pursuant to this
prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other
successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of Common Stock in other circumstances in which case the transferees, donees, pledgees or other successors in
interest will be the selling beneficial owners for purposes of this prospectus. 
 The selling stockholders and any broker-dealer or agents
participating in the distribution of the shares of Common Stock may be deemed to be “underwriters” within the meaning of Section 2(11) of the Securities Act in connection with such sales. In such event, any commissions paid, or any
discounts or concessions allowed to, any such broker-dealer or agent and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Selling Stockholders who are
“underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act and may be subject to certain statutory liabilities of, including but not limited
to, Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Securities Exchange Act of 1934, as amended, or the Exchange Act. 







 Each selling stockholder has informed the Company that it is not a registered broker-dealer and does not
have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the Common Stock. Upon the Company being notified in writing by a selling stockholder that any material arrangement has been entered into with
a broker-dealer for the sale of common stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, pursuant to Rule
424(b) under the Securities Act, disclosing (i) the name of each such selling stockholder and of the participating broker-dealer(s), (ii) the number of shares involved, (iii) the price at which such the shares of Common Stock were
sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set out or incorporated by reference
in this prospectus, and (vi) other facts material to the transaction. In no event shall any broker-dealer receive fees, commissions and markups, which, in the aggregate, would exceed eight percent (8%). 
 Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers.
In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with. 
 There can be no assurance that any selling stockholder will sell any or all of the shares of Common Stock registered pursuant to the shelf registration
statement, of which this prospectus forms a part. 
 Each selling stockholder and any other person participating in such distribution will be
subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any
of the shares of Common Stock by the selling stockholder and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making activities
with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common Stock.

 We will pay all expenses of the registration of the shares of Common Stock pursuant to the registration rights agreement, including,
without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, that each selling stockholder will pay all underwriting discounts and
selling commissions, if any and any related legal expenses incurred by it. We will indemnify the selling stockholders against certain liabilities, including some liabilities under the Securities Act, in accordance with the registration rights
agreements, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information
furnished to us by the selling stockholders specifically for use in this prospectus, in accordance with the related registration rights agreements, or we may be entitled to contribution.

 *********** 
 The undersigned agrees to promptly notify the Company of any inaccuracies or changes in the information
provided herein that may occur subsequent to the date hereof and prior to the effective date of any applicable Resale Registration Statement. All notices hereunder and pursuant to the Agreement shall be made in writing, by hand delivery, confirmed
or facsimile transmission, first-class mail or air courier guaranteeing overnight delivery at the address set forth below. In the absence of any such notification, the Company shall be entitled to continue to rely on the accuracy of the information
in this Notice and Questionnaire. 
 By signing below, the undersigned consents to the disclosure of the information contained herein in its answers to Items
(1) through (7) above and the inclusion of such information in the Resale Registration Statement and the Prospectus. The undersigned understands that such information will be relied upon by the Company in connection with the preparation or
amendment of any such Registration Statement and the Prospectus. 
 By signing below, the undersigned acknowledges that it understands its obligation to
comply, and agrees that it will comply, with the provisions of the Exchange Act and the rules and regulations thereunder, particularly Regulation M in connection with any offering of Registrable Securities pursuant to the Resale Registration
Statement. The undersigned also acknowledges that it understands that the answers to this Questionnaire are furnished for use in connection with Registration Statements filed pursuant to the Registration Rights Agreement and any amendments or
supplements thereto filed with the Commission pursuant to the Securities Act. 
 The undersigned hereby acknowledges and is advised of the following
Interpretation A.65 of the July 1997 SEC Manual of Publicly Available Telephone Interpretations regarding short selling: 
 “An Issuer filed a Form
S-3 registration statement for a secondary offering of common stock which is not yet effective. One of the selling stockholders wanted to do a short sale of common stock “against the box” and cover the short sale with registered shares
after the effective date. The issuer was advised that the short sale could not be made before the registration statement become effective, because the shares underlying the short sale are deemed to be sold at the time such sale is made. There would,
therefore, be a violation of Section 5 if the shares were effectively sold prior to the effective date.” 
 By returning this Questionnaire,
the undersigned will be deemed to be aware of the foregoing interpretation. 
 I confirm that, to the best of my knowledge and belief, the foregoing
statements (including without limitation the answers to this Questionnaire) are correct. 







 IN WITNESS WHEREOF the undersigned, by authority duly given, has caused this Questionnaire to be executed and delivered
either in person or by its duly authorized agent.
