Holder an amount in cash, as liquidated damages and not as a penalty, equal to 1.5% per month of the Subscription Amount 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 seven days after the date payable, the Company will pay interest thereon at a rate of 18% per annum (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 pro-rata basis for any portion of a month prior to the cure of an Event.

  
 3. Registration Procedures 
  
 In connection with the Company’s registration obligations hereunder,
the Company shall: 
  
 (a) Not less than three Trading Days prior
to the filing of the Registration Statement or the related Prospectus or any amendment or supplement thereto (excluding any document that would be incorporated or deemed to be incorporated therein by reference and excluding in any case any
information for which an order granting confidential treatment thereof is in effect or has been requested), the Company shall, (i) furnish to each Holder and their Special Counsel copies of all such documents proposed to be filed, which documents
(other than those incorporated or deemed to be incorporated by reference, excluding in any case any information for which an order granting 
  

 3 








 confidential treatment thereof is in effect or has been requested) will be subject to the review of such Holders and
their 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 respective 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 and their
Special Counsel shall reasonably and in good faith object, provided, the Company is notified of such objection in writing no later than two Trading Days after the Holders have been so furnished copies of such documents. 
  
 (b) (i) Prepare and file with the Commission such amendments, including
post-effective amendments, to the Registration Statement and the Prospectus used in connection therewith as may be necessary to keep the Registration Statement continuously effective as to the Registrable Securities for the Effectiveness Period 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 (subject to the terms of this Agreement), and as so
supplemented or amended to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect to the 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 the Registration Statement; 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 (subject to the terms of this Agreement) with the intended methods of disposition by the Holders thereof
set forth in the Registration Statement as so amended or in the Prospectus as so supplemented. 
  
 (c) Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (ii) through (vi) hereof shall be accompanied by an instruction to suspend the use of the Prospectus until the
requisite changes have been made) and their Special Counsel as promptly as reasonably possible (and, in the case of (i)(A) below, not less than three Trading Days prior to such filing) 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 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 such Registration Statement (the Company shall provide true and complete copies thereof and all written responses thereto to each of the Holders);
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 
  

 4 








 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; (v) of the occurrence of any event or passage of time that makes the financial
statements included in the Registration Statement ineligible for inclusion therein or 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 light of the circumstances under which they were made, not misleading and (vi) the occurrence or existence of any pending
corporate development with respect to the Company that the Company believes, in good faith, may be material and that, in the determination of the Company, makes it not in the best interests of the Company to allow continued availability of the
Registration Statement or Prospectus 
  
 (d) Promptly deliver to
each Holder and their 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. Subject to the terms of this
Agreement, 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. 
  
 (e) Use commercially
reasonable efforts to register or qualify the resale of such Registrable Securities as required under applicable securities or Blue Sky laws of each State within the United States as any Holder requests in writing, and to keep each such registration
or qualification (or exemption therefrom) effective during the Effectiveness Period; provided, that the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or subject the Company to
any material tax in any such jurisdiction where it is not then so subject. 
  
 (f) Cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to the Registration Statement, which
certificates shall be free, to the extent permitted by the Purchase Agreement, 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 request.

  
 (g) Upon the occurrence of any event contemplated this Section
3, as promptly as reasonably 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 
  

 5 








 material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. If the Company notifies the Holders in accordance with clauses (ii) through (vi) of Section 3(c) above to suspend the use of the use of any Prospectus until the requisite
changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will use its best efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable, except that in the case of
suspension of the availability of the Registration Statement and Prospectus pursuant to clause (vi) of Section 3(c), the Company shall not be required to take such action until such time as it shall determine, in good faith, that the continued
availability of the Registration Statement and Prospectus is no longer not in the best interests of the Company. The Company shall be entitled to exercise its right under this Section 3(g) to suspend the availability of the Registration Statement
and Prospectus, subject to the payment of liquidated damages pursuant to Section 2(c), for a period not to exceed 15 consecutive days or for multiple periods not to exceed 25 days in any 12 month period. 
  
 (h) Comply with all applicable rules and regulations of the Commission.

  
 (i) Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of (i) any order suspending the effectiveness of the Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any
jurisdiction, at the earliest practicable moment. 
  
 (j) The
Company may require, at any time prior to the third Trading Day prior to the Filing Date, each Holder to furnish to the Company a statement as to the number of shares of Common Stock beneficially owned by such Holder and, if requested by the
Commission, the controlling person thereof, within three Trading Days of the Company’s request. 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 shall be tolled until such information is delivered to the Company.

  
 4. Registration Expenses. All fees and expenses
incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company 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 (including, without limitation, fees and expenses (A) with respect to filings required to be made with Nasdaq or such other market on which the Common Stock
is then listed for trading, and (B) in compliance with applicable state securities or Blue Sky laws (including, without limitation, fees 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 requested by the 
  

 6 








 Holders), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company, and
(v) 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 broker or similar commissions or, except to the extent
provided for in the Agreements, 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 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 reasonable 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, the 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 the Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to
the extent, but only to the extent, that (1) such untrue statements or omissions or alleged untrue statements or omissions are based 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 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 or (2) in the case of an occurrence of an event of the type specified in Section 3(c)(ii)-(vi), 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). 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. 
  

 7 








 (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 determined by a court of competent jurisdiction in a final judgment not subject to appeal or review) arising out of or based upon any
untrue statement of a material fact contained in the Registration Statement, the Prospectus, or any form of prospectus, or in any amendment or supplement thereto, or arising out of or based upon: (i) such Holder’s failure to comply with the
prospectus delivery requirements of the Securities Act provided that the Company has either provided the Holder with copies of such Prospectus or made them available from an online source or (ii) any omission of a material fact required to be stated
therein or necessary to make the statements therein 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 to the Company specifically for
inclusion in the Registration Statement or such Prospectus or to the extent that (1) such untrue statements or omissions are based 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 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 or (2) in the case of an occurrence of an event of the type specified in Section 3(c)(ii)-(vi), 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 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 such failure shall have 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 
  

 8 








 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 material conflict of interest is likely to exist 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 Party,
the Indemnifying Party shall not have the right to assume the defense thereof and the expense of one such counsel for each Holder shall be at the expense of the Indemnifying Party). 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. 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 ten Trading 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 (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. 
  

 9 








 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 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. 
  
 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. 
  
 6. Miscellaneous 
  
 (a) 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 each Holder
of 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 a Holder and that does not directly or indirectly
affect the rights of other Holders may be given by any Holder as to itself. 
  
 (b) No Inconsistent Agreements. The Company has not entered, as of the date hereof, 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 would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Except as and to the extent specified in the Disclosure Schedules, neither the
Company nor any of its subsidiaries has previously entered into any agreement granting any registration rights with respect to any of its securities to any Person that have not been satisfied in full. 
  
 (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 the Registration Statement provided that the Company has either provided the Holder with copies of
such Prospectus or made them available from an online source. 
  
 (d) Discontinued Disposition. 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), 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(g), or
until it is advised in writing (the 
  

 10 








 “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. The Company may provide appropriate stop orders to enforce the provisions of
this paragraph. 
  
 (e) Piggy-Back Registrations. If at any
time during the Effectiveness Period there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering
for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, then the Company shall send to each Holder written notice of such determination
and, if within fifteen days after receipt of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such holder requests to be registered;
provided, that, the Company shall not be required to register any Registrable Securities pursuant to this Section 6(f) that are eligible for resale pursuant to Rule 144(k) promulgated under the Securities Act. 
  
 (f) 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. 
  
 (g) 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. The Company may not assign its rights or obligations hereunder without the prior written consent Holders of at least 75% of the then-outstanding Registrable Securities. Each Holder may assign
their respective rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement. 
  
 (h) 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. 
  
 (i) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and
construed and enforced in accordance with the internal laws of the State of Delaware, without regard to the principles of conflicts of law thereof. If either party shall commence a Proceeding to enforce any provisions of this Agreement, then the
prevailing party in such Proceeding 
  

 11 








 shall be reimbursed by the other party for its attorneys fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such Proceeding. 
  
 (j) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any remedies provided by law. 
  
 (k) 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 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. 
  
 (l) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof. 
  
 (m) Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor hereunder is several and not joint with the obligations of any other Investor hereunder, and no Investor shall
be responsible in any way for the performance of the obligations of any other Investor hereunder. Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any Investor pursuant hereto or
thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert with respect to such obligations or the
transactions contemplated by this Agreement. Each Investor 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 Investor to be joined
as an additional party in any proceeding for such purpose. Many Investors were introduced to the Company by SG Cowen Securities Corporation, which has acted solely as agent for the Company and not for any Investor. Each Investor has been represented
by its own separate legal counsel in their review and negotiation of the Transaction Documents. For reasons of administrative convenience only, Investors and their respective counsel may have chosen to communicate with the Company through one
counsel.

 Annex A 
  
 Plan of Distribution 
  
 The Selling Stockholders and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of Common
Stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. 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 Investors; 

  

	 	•	 	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; 

  

	 	•	 	short sales 

  

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

  

	 	•	 	a combination of any such methods of sale; and 

  

	 	•	 	any other method permitted pursuant to applicable law. 

  
 The Selling Stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus. Broker-dealers
engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the Investor of shares,
from the Investor) in amounts to be negotiated. The Selling Stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. 
  
 The selling stockholder may from time to time pledge or grant a security interest in some or all of the Shares or common
stock or Warrant 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 under this prospectus, or under an amendment to this
prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to 
  

 15 








 include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

  
 The selling stockholders also may transfer the shares of
common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus. 
  
 The Selling Stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be
“underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents 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. The Selling Stockholders have informed the Company that none of them have any agreement or understanding, directly or indirectly, with any person to distribute the Common Stock.

  
 The Company is required to pay all fees and expenses incurred
by the Company incident to the registration of the shares. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
