	 	3.	Registration Procedures. 

 In
connection with the Company’s registration obligations hereunder, the Company shall: 
 (a) Prepare and file with the
Commission on or prior to the Filing Date, a Registration Statement on Form S-3 (or if the Company is not then eligible to register for resale the Registrable Securities on Form S-3 such registration shall be on another appropriate form in
accordance with the Securities Act and the rules promulgated thereunder) in accordance with the method or methods of distribution thereof as specified by the Holders (except if otherwise directed by the Holders), and use its reasonable best efforts
to cause the Registration Statement to become effective and remain effective as provided herein; provided, however, that not less than five (5) Business Days prior to the filing of the Registration Statement or any related
Prospectus (other than documents incorporated by reference therein) or any amendment or supplement thereto, and not less than one (1) Business Day prior to the filing of any document that would be incorporated therein by reference, the Company
shall (i) furnish to the Holders and any Special Counsel, copies of all such documents proposed to be filed, which documents (other than those incorporated by reference) will be subject to the review of such Holders and such Special Counsel,
and (ii) cause its officers and directors, counsel and independent certified public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of Special Counsel, to conduct a reasonable investigation within the
meaning of the Securities Act. The Company shall not file the Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable Securities or the Special Counsel shall
reasonably object in writing within three (3) Business Days of their receipt thereof. 
 (b) Prepare and file with the
Commission such amendments, including post-effective amendments, to the Registration Statement as may be necessary to keep the Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and
prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any
required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; (iii) respond as promptly as possible, but in no event later than
ten (10) Business Days, to any comments received from the Commission with respect to the Registration Statement or any amendment thereto and as promptly as possible provide the Holders true and complete copies of all correspondence from and to
the Commission relating to the Registration Statement, provided that 

  

 -4- 








 
the Company shall not provide to the Holders any correspondence that contains any material non-public information; and (iv) comply in all material
respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by the Registration Statement during the applicable period in accordance with the intended methods of
disposition by the Holders thereof set forth in the Registration Statement as so amended or in such Prospectus as so supplemented. 
 (c) Notify the Holders of Registrable Securities to be sold and the Special Counsel as promptly as possible (and, in the case of (i)(A) below, not less than five (5) days prior to such filing) and (if requested by any such Person)
confirm such notice in writing no later than one (1) Business Day following the day (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to the Registration Statement is filed; (B) when the Commission notifies
the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration Statement and (C) with respect to the 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 the Registration Statement or Prospectus or for additional information;
(iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) if at any
time any of the representations and warranties of the Company contained in any agreement contemplated hereby ceases to be true and correct in all material respects; (v) 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 (vi) of the occurrence of any event that
makes any statement made in the 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 the Registration Statement,
Prospectus or other documents so that, in the case of the 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 light of the circumstances under which they were made, not misleading. 
 (d)
Use its reasonable 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 Securities for sale in any jurisdiction, at the earliest practicable moment. 
 (e)
If requested by the Holders of a majority of the Registrable Securities, (i) promptly incorporate in a Prospectus supplement or post-effective amendment to the Registration Statement such information as the Company reasonably agrees should be
included therein and (ii) make all required filings of such Prospectus supplement or such post-effective amendment as soon as practicable after the Company has received notification of the matters to be incorporated in such Prospectus
supplement or post-effective amendment. 
  

 -5- 








 (f) Furnish to each Holder and the Special Counsel, without charge, at least one
conformed copy of each Registration Statement and each amendment thereto, including financial statements and schedules, and, to the extent requested by such Person, all documents incorporated or deemed to be incorporated therein by reference, and
all exhibits (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission. 
 (g) Promptly deliver to each Holder and the Special Counsel, without charge, as many copies of the Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as such
Persons may reasonably request; and the Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by
such Prospectus and any amendment or supplement thereto. 
 (h) Prior to any public offering of Registrable Securities, use
its reasonable best efforts to register or qualify or cooperate with the selling Holders and the Special Counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Holder requests in writing, to keep each such registration or qualification (or exemption therefrom) effective during the
Effectiveness Period and to do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by a Registration Statement; provided, however, that the
Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so
subject or subject the Company to any material tax in any such jurisdiction where it is not then so subject. 
 (i) Cooperate
with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold pursuant to a Registration Statement, which certificates shall be free of all restrictive legends, and to enable such
Registrable Securities to be in such denominations and registered in such names as any Holder may request at least two (2) Business Days prior to any sale of Registrable Securities. 
 (j) Upon the occurrence of any event contemplated by Section 3(c)(vi), as promptly as possible, prepare a supplement or amendment,
including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter
delivered, neither the Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading. 
 (k) Use its reasonable best efforts to cause all Registrable
Securities relating to the Registration Statement to be listed on The Nasdaq Capital Market, OTC Bulletin Board or 

  

 -6- 








 
any other securities exchange, quotation system or market, if any, on which similar securities issued by the Company are then listed as and when required
pursuant to the Purchase Agreement. 
 (l) Comply in all material respects with all applicable rules and regulations of the
Commission and make generally available to its security holders earning statements satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 not later than 45 days after the end of any 12-month period (or 90 days after the
end of any 12-month period if such period is a fiscal year) commencing on the first day of the first fiscal quarter of the Company after the effective date of the Registration Statement, which statement shall conform to the requirements of Rule 158.

 (m) The Company may require each selling Holder to furnish to the Company information regarding such Holder and the
distribution of such Registrable Securities as is required by law to be disclosed in the Registration Statement, and the Company may exclude from such registration the Registrable Securities of any such Holder who fails to furnish such information
within a reasonable time after receiving such request. 
 If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall have the right to require (if such reference to such 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 Holder in any amendment or supplement to the Registration Statement filed or prepared subsequent to the time that such reference ceases to be required. 
 Each Holder covenants and agrees that (i) it will not sell any Registrable Securities under the Registration Statement until it has
received copies of the Prospectus as then amended or supplemented as contemplated in Section 3(g) and notice from the Company that such Registration Statement and any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will comply with the prospectus delivery requirements of the Securities Act as applicable to them in connection with sales of Registrable Securities pursuant to
the Registration Statement. 
 Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a
notice from the Company of the occurrence of any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or 3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration
Statement until such Holder’s receipt of the copies of the supplemented Prospectus and/or amended Registration Statement contemplated by Section 3(j), or until it is advised in writing (the “Advice”) by the Company that
the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement.

 (n) If (i) there is material non-public information regarding the Company which the Company’s Board of Directors
(the “Board”) reasonably determines not to be in the Company’s best interest to disclose and which the Company is not otherwise required to disclose, 

  

 -7- 








 
or (ii) there is a significant business opportunity (including, but not limited to, the acquisition or disposition of assets (other than in the ordinary
course of business) or any merger, consolidation, tender offer or other similar transaction) available to the Company which the Board reasonably determines not to be in the Company’s best interest to disclose, then the Company may postpone or
suspend filing or effectiveness of a registration statement for a period not to exceed 30 consecutive days, provided that the Company may not postpone or suspend its obligation under this Section 3(n) for more than 45 days in the aggregate
during any 12 month period; provided, however, that no such postponement or suspension shall be permitted for consecutive 30 day periods, arising out of the same set of facts, circumstances or transactions. 
  

	 	4.	Registration Expenses. 

 All fees
and expenses incident to the performance of or compliance with this Agreement by the Company, except as and to the extent specified in this Section 4, shall be borne by the Company whether or not the Registration Statement is filed or becomes
effective and whether or not any Registrable Securities are sold pursuant to the Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees

	 	5.	Indemnification. 

 (a)
Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors, agents, brokers (including brokers who offer and sell Registrable
Securities as principal as a result of a pledge or any failure to perform under a margin call of Common Stock), investment advisors 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, 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, costs of preparation and attorneys’ fees) and expenses (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material
fact contained in the 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 form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading; provided that
(i) the foregoing indemnity shall not apply to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding such Holder or such other Indemnified Party furnished in writing to the
Company by such Holder expressly for use therein, which information was reasonably relied on by the Company for use therein or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of
Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto, and (ii) the
foregoing indemnity shall not inure to a Holder or to any Person from whom the Person asserting any Loss purchased Registrable Securities if copies of the Prospectus were timely delivered to the Holders or their representatives pursuant hereto and a
copy of the Prospectus (as then amended and supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Holder or such other Person to the Person asserting such Loss, if
required by law so to have been delivered, at or prior to the written confirmation of the sale of any Registrable Securities to such Person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such Loss.
The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement. 
 (b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, the
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 determined by a court of competent jurisdiction in a final judgment not subject to any appeal or review), as incurred, to the extent arising
solely out of or based solely upon any untrue statement of a material fact contained in the Registration Statement, any Prospectus, or any form of prospectus, or arising solely out of or based solely upon any omission of a material fact required to
be stated therein or necessary to make the statements therein (in the case of any 

  

 -9- 








 
Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, to the extent, but only
to the extent, that such untrue statement or omission is contained in any information so furnished in writing by such Holder or other Indemnified Party to the Company specifically for inclusion in the Registration Statement or such Prospectus and
that such information was reasonably relied upon by the Company for use in the Registration Statement, such Prospectus or such form of prospectus or to the extent that such information relates to such Holder or such Holder’s proposed method of
distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of Prospectus. Notwithstanding anything to the contrary contained
herein, the Holders shall be liable under this Section 5(b) for only that amount as does not exceed the net proceeds to such Holder as a result of the sale of Registrable Securities pursuant to such Registration Statement. 
 (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 promptly shall notify the Person from whom indemnity is sought (the “Indemnifying Party) in writing, and the Indemnifying Party shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal
or further review) that such failure shall have proximately and materially 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; or (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 (which shall be reasonably acceptable to the Indemnifying Party) that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, the Indemnifying Party
shall be responsible for reasonable fees and expenses of no more than one counsel for 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 or delayed. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such
settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding. 
  

 -10- 








 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 ten (10) Business Days of written notice
thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder). 
 (d) Contribution. If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party because of
a failure or refusal of a governmental authority to enforce such indemnification in accordance with its terms (by reason of public policy or otherwise), 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 Section 5(c), 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. 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. 
 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. Notwithstanding anything to the contrary contained herein, the Holders shall be liable under this Section 5(d) for only that amount as does not exceed the net proceeds to such
Holder as a result of the sale of Registrable Securities pursuant to the Registration Statement giving rise to such indemnity or contribution obligation.

	 	6.	Rule 144. 

 As long as any Holder
owns any Registrable Securities or Warrants, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to
Section 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. As long as any Holder owns any Registrable Securities or Warrants, if the Company is not required to file reports
pursuant to Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the Holders and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act annual and quarterly financial statements,
together with a discussion and analysis of such financial statements in form and substance substantially similar to those that would otherwise be required to be included in reports required by Section 13(a) or 15(d) of the Exchange Act, as well
as any other information required thereby, in the time period that such filings would have been required to have been made under the Exchange Act. The Company further covenants that it will take such further action as any Holder may reasonably
request, all to the extent required from time to time to enable such Person to sell the Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the
Securities Act, including providing any legal opinions relating to such sale pursuant to Rule 144. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has
complied with such requirements. 
  

	 	7.	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 Inconsistent Agreements. Neither the Company nor any of its subsidiaries has, as of the date hereof entered
into and currently in effect, nor shall the Company or any of its subsidiaries, on or after the date of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. Except as disclosed in Schedule 2.1(c) of the Purchase Agreement or Schedule II hereto, neither the Company nor any of its subsidiaries has previously entered into any
agreement currently in effect granting any registration rights with respect to any of its securities to any Person. Without limiting the generality of the foregoing, without the written consent of the Holders of a majority of the then outstanding
Registrable Securities, the Company shall not grant to any Person the right to request the Company to register any securities of the Company, under the Securities Act unless the rights 

  

 -12- 








 
so granted are subject in all respects to the prior rights in full of the Holders set forth herein, and are not otherwise in conflict with the provisions of
this Agreement. 
 (c) No Piggyback on Registrations. Neither the Company nor any of its security holders (other than
the Holders in such capacity pursuant hereto or as disclosed on Schedule 2.1(c) of the Purchase Agreement or Schedule II hereto) may include securities of the Company in the Registration Statement, and the Company shall not after the
date hereof enter into any agreement providing such right to any of its securityholders, unless the right so granted is subject in all respects to the prior rights in full of the Holders set forth herein, and is not otherwise in conflict with the
provisions of this Agreement. 
 (d) Amendments and Waivers. The provisions of this Agreement, including the provisions
of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and the Holders of a majority of the
Registrable Securities outstanding. 
 (e) Failure to File Registration Statement and Other Events. The Company and the
Purchasers agree that the Holders will suffer damages if the Registration Statement is not filed on or prior to the Filing Date and not declared effective by the Commission on or prior to the Effectiveness Date and maintained in the manner
contemplated herein during the Effectiveness Time or if certain other events occur. The Company and the Holders further agree that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if (A) the
Registration Statement is not filed on or prior to the Filing Date, or (B) the Registration Statement is not declared effective by the Commission on or prior to the 120th day after the Closing Date, or (C) the Company fails to file with the Commission a request for acceleration in accordance with Rule 461 promulgated under
the Securities Act within five (5) Business Days of the date that the Company is notified (orally or in writing, whichever is earlier) by the Commission that a Registration Statement will not be “reviewed,” or not subject to further
review, or (D) the Registration Statement is filed with and declared effective by the Commission but thereafter ceases to be effective as to all Registrable Securities at any time prior to the expiration of the Effectiveness Period, without
being succeeded immediately by a subsequent Registration Statement filed with and declared effective by the Commission, or (E) the Company has breached Section 3(n), or (F) trading in the Common Stock shall be suspended or if the
Common Stock is delisted from both The Nasdaq Capital Market and the OTC Bulletin Board for any reason for more than five Business Days in the aggregate (any such failure or breach being referred to as an “Event,” and for purposes
of clauses (A) and (B) the date on which such Event occurs, or for purposes of clause (C) the date on which such five Business Day period is exceeded, or for purposes of clause (D) after more than fifteen Business Days, or for
purposes of clause (F) the date on which such five Business Day period is exceeded, being referred to as “Event Date”), then the Company shall pay an amount as liquidated damages to each Holder equal to 3% for the first
calendar month and 1.5% per calendar month thereafter or portion thereof of the Holder’s initial investment in the Shares from the Event Date (provided that, with respect to the Event described in clause (B), the “first calendar
month” shall be deemed to commence on the 30th day prior to the applicable Event Date) until the applicable
Event is cured; 

  

 -13- 








 
provided, that, liquidated damages for the first calendar month upon the occurrence of an Event shall be payable in cash only, and for each
calendar month thereafter shall be payable at the Company’s option in cash or shares of Common Stock. Notwithstanding anything to the contrary in this paragraph (e), if (I) any of the Events described in clauses (A), (B), (C) or
(D) shall have occurred, (II) on or prior to the applicable Event Date, the Company shall have exercised its rights under Section 3(n) hereof and (III) the postponement or suspension permitted pursuant to such Section 3(n) shall
remain effective as of such applicable Event Date, then the applicable Event Date shall be deemed instead to occur on the second Business Day following the termination of such postponement or suspension. If the Company elects to pay in shares of
Common Stock, the number of such shares of Common Stock to be issued to the Holders pursuant to this paragraph (e) shall be based on the liquidated damage amount divided by the average closing bid price of the Common Stock for the five trading
days prior to such Event Date and shall be issuable promptly upon receipt by the Company of a written demand from a Holder made on or after the Event Date. 
 (f) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earlier of (i) the
date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified for notice prior to 5:00 p.m., New York City time, on a Business Day, (ii) the Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified for notice later than 5:00 p.m., New York City time, on any date and earlier than 11:59 p.m., New York City time, on such date,
(iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service or (iv) actual receipt by the party to whom such notice is required to be given. The addresses for such communications shall
be with respect to each Holder at its address set forth under its name on Schedule I attached hereto with copies (which shall not constitute notice) to:

 (g) Successors and Assigns. This Agreement shall be binding upon and inure to the
benefit of the parties and their successors and permitted assigns and shall inure to the benefit of each Holder and its successors and assigns. The Company may not assign this Agreement or any of its rights or obligations hereunder without the prior
written consent of each Holder. Each Purchaser may assign its rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement. 
 (h) Assignment of Registration Rights. The rights of each Holder hereunder, including the right to have the Company register for resale Registrable Securities in accordance with the terms of this Agreement,
shall be automatically assignable by each Holder to any Affiliate of such Holder or any other Holder or Affiliate of any other Holder of all or a portion of the Registrable Securities if: (i) the Holder agrees in writing with the transferee or
assignee to assign such rights, 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 (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights are being transferred or assigned, (iii) following such transfer or assignment the further
disposition of such securities by the transferee or assignees is restricted under the Securities Act and applicable state securities laws, (iv) at or before the time the Company receives the written notice contemplated by clause (ii) of
this Section, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions of this Agreement, and (v) such transfer shall have been made in accordance with the applicable requirements of the Purchase
Agreement. In addition, each Holder shall have the right to assign its rights hereunder to any other Person with the prior written consent of the Company, which consent shall not be unreasonably withheld. The rights to assignment shall apply to the
Holders (and to subsequent) successors and assigns. 
 (i) Counterparts. This Agreement may be executed in any number
of 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. In the event that any signature is delivered by facsimile transmission, such signature
shall create a valid binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature were the original thereof. 
 (j) Governing Law; Jurisdiction. 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. This Agreement shall not be interpreted or construed with any presumption
against the party causing this Agreement to be drafted. The Company and the Holders agree that venue for any dispute arising under this Agreement will lie exclusively in the state or federal courts located in New York County, New York, and the
parties irrevocably waive any right to raise forum non conveniens or any other argument that New York is not the proper venue. The Company and the Holders irrevocably consent to personal jurisdiction in the state and federal courts of the
state of New York. The Company and the Holders consent to process 

  

 -15- 








 
being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing in this Section 7(j) shall affect or limit any right to serve process in any other manner permitted by law. The Company and the
Holders hereby agree that the prevailing party in any suit, action or proceeding arising out of or relating to this Agreement or the Purchase Agreement, shall be entitled to reimbursement for reasonable legal fees from the non-prevailing party. The
parties hereby waive all rights to a trial by jury. 
 (k) Cumulative Remedies. The remedies provided herein are
cumulative and not exclusive of any remedies provided by law. 
 (l) Severability. If any term, provision, covenant or
restriction of this Agreement is held to be invalid, illegal, void or unenforceable in any respect, 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 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. 
 (m) Headings. The headings herein are for convenience only, do not constitute a part
of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. 
 (n) Shares Held by the
Company and its Affiliates. Whenever the consent or approval of Holders of a specified percentage of Registrable Securities is required hereunder, Registrable Securities held by the Company or its Affiliates (other than any Holder or transferees
or successors or assigns thereof if such Holder is deemed to be an Affiliate solely by reason of its holdings of such Registrable Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such
required percentage. 
 (o) Independent Nature of Purchasers. The Company acknowledges that the obligations of each
Purchaser under the Transaction Documents are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under the Transaction
Documents. The Company acknowledges that the decision of each Purchaser to purchase Securities pursuant to the Purchase Agreement has been made by such Purchaser independently of any other Purchaser and independently of any information, materials,
statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of its Subsidiaries which may have made or given by any other
Purchaser or by any agent or employee of any other Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any Purchaser (or any other person) relating to or arising from any such information, materials, statements
or opinions. The Company acknowledges that nothing contained herein, or in any Transaction Document, and no 

  

 -16- 








 
action taken by any Purchaser pursuant hereto or thereto (including, but not limited to, the (i) inclusion of a Purchaser in the Registration Statement
and (ii) review by, and consent to, such Registration Statement by a Purchaser) 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 or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. The Company acknowledges that each Purchaser shall be entitled to independently protect and
enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, 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 for reasons of administrative convenience only, the Transaction Documents have been prepared by counsel for the placement agent and such counsel does not represent the Purchasers. The Company
acknowledges that it has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by the Purchasers.
