 2. Resale Registration. 
 (a) On or prior to the Filing Date, the Company shall prepare and file with the Commission a “resale” Registration Statement
providing for the resale of all Registrable Securities by means of an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be on Form SB-2 (except if the Company is not then eligible to register for resale
the Registrable Securities on Form SB-2, in which case such registration shall be on another appropriate form in accordance herewith and the Securities Act and the rules promulgated thereunder). Such Registration Statement shall cover to the extent
allowable under the Securities Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock resulting from stock splits, stock dividends or similar transactions with respect to the
Registrable Securities. The Company shall (i) not permit any securities other than the Registrable Securities and the securities listed on Schedule II hereto to be included in the Registration Statement and (ii) use its best efforts
to cause the Registration Statement to be declared effective under the Securities Act as promptly as possible after the filing thereof, but in any event prior to the Effectiveness Date, and to keep such Registration Statement continuously effective
under the Securities Act until such date as is the earlier of (x) the date when all Registrable Securities covered by such Registration Statement have been sold or (y) the date on which the Registrable Securities may be sold without any
restriction pursuant to Rule 144(k) as determined by the counsel to the Company pursuant to a written opinion letter, addressed to the Company’s transfer agent to such effect (the “Effectiveness Period”). The Company shall
request that the effective time of the Registration Statement be 4:00 p.m. Eastern Time on the effective date. If at any time and for any reason, an additional Registration Statement is required to be filed because at such time the actual number of
shares of Common Stock into which the Preferred Stock is convertible and the Warrants are exercisable plus the number of shares of Common Stock previously issued upon such conversion and exercise exceeds the number of shares of Registrable
Securities remaining under the Registration Statement, the Company shall have twenty (20) Business Days to file such additional Registration Statement, and the Company shall use its best efforts to cause such additional Registration Statement
to be declared effective by the Commission as soon as possible, but in no event later than sixty (60) days after filing. 
 (b) Notwithstanding anything to the contrary set forth in this Section 2, in the event the Commission does not permit the Company to register all of the Registrable Securities in the Registration Statement because of the
Commission’s application of Rule 415, the Company shall register in the Registration Statement such number of Registrable Securities as is permitted by the Commission, provided, however, that the number of Registrable Securities
to be included in such Registration Statement or any subsequent registration statement shall be determined in the following order: (i) first, the shares of Common Stock issuable upon conversion of the Company’s Series B Preferred Stock or
upon exercise of the Warrants issued concurrently with such Series B Preferred Stock shall be registered on a pro rata basis among the holders of the Series B Preferred Stock; (ii) second, the shares of Common Stock issuable upon conversion of
the Preferred Stock shall be registered on a pro rata basis among the holders of the Preferred Stock; (iii) third, the shares of Common Stock issuable upon exercise of the C-2 Warrants shall be registered on a pro rata basis among the holders
of the C-2 Warrants; (iv) fourth, the shares of Common Stock issuable upon exercise of the C-1 Warrants shall be registered on a pro rata basis among the holders of the C-1 Warrants; and (v) fifth, the shares of 

  

 4 








 
Common Stock issuable upon exercise of the C-3 Warrants shall be registered on a pro rata basis among the holders of the C-3 Warrants. In the event the
Commission does not permit the Company to register all of the Registrable Securities in the initial Registration Statement, the Company shall use its best efforts to file subsequent Registration Statements to register the Registrable Securities that
were not registered in the initial Registration Statement as promptly as possible and in a manner permitted by the Commission. For purposes of this Section 2(b), “Filing Date” means with respect to each subsequent Registration
Statement filed pursuant hereto, the later of (i) sixty (60) days following the sale of substantially all of the Registrable Securities included in the initial Registration Statement or any subsequent Registration Statement and
(ii) six (6) months following the effective date of the initial Registration Statement or any subsequent Registration Statement, as applicable, or such earlier date as permitted by the Commission. For purposes of this Section 2(b),
“Effectiveness Date” means with respect to each subsequent Registration Statement filed pursuant hereto, the earlier of (A) the ninetieth (90th) day following the filing date of such Registration Statement (or in the event such Registration Statement receives a “full review” by the Commission, the one hundred twentieth (120th) day following such filing date) or (B) the date which is within three (3) Business Days after the date on which the Commission informs the Company (i) that the
Commission will not review such Registration Statement or (ii) that the Company may request the acceleration of the effectiveness of such Registration Statement; provided that, if the Effectiveness Date falls on a Saturday, Sunday or any
other day which shall be a legal holiday or a day on which the Commission is authorized or required by law or other government actions to close, the Effectiveness Date shall be the following Business Day. 
 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 SB-2 (or if the Company is not then eligible to register for resale the Registrable Securities on Form SB-2 such registration shall be on another appropriate form
in accordance herewith and the Securities Act and the rules promulgated thereunder) in accordance with the plan of distribution as set forth on Exhibit A hereto and in accordance with applicable law, and 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 or any amendment or supplement
thereto, the Company shall (i) furnish to the Holders and any Special Counsel, copies of all such documents proposed to be filed, which documents 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 review of such documents. 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 any Special Counsel shall reasonably object in writing within three (3) Business
Days of their receipt thereof. 
  

 5 








 (b)(i) 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 as necessary 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; (iv) file the final prospectus pursuant to Rule 424 of the Securities Act no later than 9:00 a.m. Eastern Time on the Business Day following the date the Registration Statement is declared effective by the Commission;
and (v) 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 Effectiveness 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 and any Special Counsel as promptly as possible (and, in the case of (i)(A) below, not
less than three (3) Business Days prior to such filing, and in the case of (iii) below, on the same day of receipt by the Company of such notice from the Commission) 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 or threatening 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. 
  

 6 








 (d) Use its best efforts to avoid the issuance of, or, if issued, obtain the withdrawal
of, as promptly as possible, (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. 
 (e) If requested by the Holders of a majority in interest 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. 
 (f) If requested by any Holder, furnish to such Holder and any Special Counsel, without charge, at least one conformed copy of each
Registration Statement and each amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference, 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. 
 (g)
Promptly deliver to each Holder and any 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
subject to the provisions of Sections 3(m) and 3(n), 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 best efforts to register or qualify or cooperate with the selling Holders and any 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, to the extent permitted by the Purchase Agreement
and applicable federal and state securities laws, shall be free of all restrictive legends, and to enable such 

  

 7 








 
Registrable Securities to be in such denominations and registered in such names as any Holder may request in connection with 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 best efforts to cause
all Registrable Securities relating to the Registration Statement to be listed or quoted on the OTC Bulletin Board or any other securities exchange, quotation system or market, if any, on which similar securities issued by the Company are then
listed or traded 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 all documents filed or required to be filed with the Commission, including, but not limited, to, 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, Prospectus, or any amendment or supplement thereto, and the Company may exclude from such registration the Registrable Securities of any such Holder who unreasonably 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 it will not sell any Registrable Securities under the Registration Statement until the Company has
electronically filed the Prospectus as then amended or supplemented as contemplated in Section 3(g) and notice from the Company that the Registration Statement and any post-effective amendments thereto have become effective as contemplated by
Section 3(c). 
  

 8 








 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), 3(c)(vi) or 3(n), 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”) determines not to be in the Company’s best interest to disclose and which the Company is not otherwise required to disclose, (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 determines not to be in the
Company’s best interest to disclose, or (iii) the Company is required to file a post-effective amendment to the Registration Statement to incorporate the Company’s quarterly and annual reports and audited financial statements on Forms
10-QSB and 10-KSB, then the Company may (x) postpone or suspend filing of a registration statement for a period not to exceed thirty (30) consecutive days or (y) postpone or suspend effectiveness of a registration statement for a
period not to exceed twenty (20) consecutive days; provided that the Company may not postpone or suspend effectiveness of a registration statement under this Section 3(n) for more than forty-five (45) days in the aggregate during any
three hundred sixty (360) day period; provided, however, that no such postponement or suspension shall be permitted for consecutive twenty (20) day periods arising out of the same set of facts, circumstances or transactions.

listing of the Registrable Securities on any securities exchange if required hereunder. The Company shall not be responsible for any discounts, commissions, transfer taxes or other similar fees incurred by the Holders in connection with the sale of

 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, managers, partners, members, shareholders, agents, brokers, 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 violation of securities laws or 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, except 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
for use therein. 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, 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 and employees of such
controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, 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 in any 

  

 10 








 
amendment or supplement thereto, 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 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 Indemnifying Party to the Company specifically for inclusion in the Registration Statement or such Prospectus. Notwithstanding anything to the contrary
contained herein, each Holder shall be liable under this Section 5(b) for only that amount as does not exceed the gross 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 promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying
Party shall be entitled to 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 parties shall have been advised by counsel 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, 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 such
counsel 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 or delayed. No
Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened Proceeding in respect of which any Indemnified Party is a party and indemnity has been sought hereunder, unless
such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding. 
 All indemnifiable fees and expenses of the Indemnified Party (including reasonable fees and expenses 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 

  

 11 








 
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 Indemnified Party shall 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 due
but 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 benefits received by the Indemnifying Party on the
one hand and the Indemnified Party on the other from the offering of the Preferred Stock and Warrants. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be
made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault, as applicable, 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. In no event shall any selling Holder be required to contribute an amount under this Section 5(d) in excess of the
gross proceeds received by such Holder upon sale of such Holder’s Registrable Securities pursuant to the Registration Statement giving rise to such contribution obligation. 
 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 pursuant to the law.

 6. Rule 144. 
 As long as any Holder owns Preferred Stock, Warrants or Registrable Securities, 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. As long as any Holder owns Preferred Stock, Warrants
or Registrable Securities, 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 reasonably required from time to time to enable such Person to sell Conversion Shares and Warrant Shares 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, such 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 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.

  

 13 








 (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 in 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 security holders, 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) Piggy-Back Registrations. If at any time when there is not an
effective Registration Statement covering (i) Conversion Shares or (ii) Warrant Shares, 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, the Company shall send to each holder of Registrable Securities written notice of such determination and, if within
thirty (30) days after receipt of such notice, or within such shorter period of time as may be specified by the Company in such written notice as may be necessary for the Company to comply with its obligations with respect to the timing of the
filing of such registration statement, any such holder shall so request in writing (which request shall specify the Registrable Securities intended to be disposed of by the Purchasers), the Company will cause the registration under the Securities
Act of all Registrable Securities which the Company has been so requested to register by the holder, to the extent requisite to permit the disposition of the Registrable Securities so to be registered, provided that if at any time after giving
written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration
of such securities, the Company may, at its election, give written notice of such determination to such holder and, thereupon, (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration (but not from its obligation to pay expenses in accordance with Section 4 hereof), and (ii) in the case of a determination to delay registering, shall be permitted to delay registering any
Registrable Securities being registered pursuant to this Section 7(d) for the same period as the delay in registering such other securities. The Company shall include in such registration statement all or any part of such Registrable Securities
such holder requests to be registered; provided, however, that the Company shall not be required to register any Registrable Securities pursuant to this Section 7(d) that are eligible for sale pursuant to Rule 144(k) of the
Securities Act. In the case of an underwritten public offering, if the managing underwriter(s) or underwriter(s) should reasonably object to the inclusion of the Registrable Securities in such registration statement, then if the Company after
consultation with the managing underwriter should reasonably determine that the inclusion of such Registrable Securities would materially adversely affect the offering contemplated in such registration statement, and based on such determination
recommends inclusion in such registration statement of fewer or none of the Registrable Securities of the Holders, then (x) the number of Registrable Securities of the Holders included in such registration statement shall be reduced pro-rata
among such Holders (based upon the number of Registrable Securities requested to be included in the 

  

 14 








 
registration), if the Company after consultation with the underwriter(s) recommends the inclusion of fewer Registrable Securities, or (y) none of the
Registrable Securities of the Holders shall be included in such registration statement, if the Company after consultation with the underwriter(s) recommends the inclusion of none of such Registrable Securities; provided, however, that
if securities are being offered for the account of other persons or entities as well as the Company, such reduction shall not represent a greater fraction of the number of Registrable securities intended to be offered by the Holders than the
fraction of similar reductions imposed on such other persons or entities (other than the Company). 
 (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 Period 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 Effectiveness 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 three (3) 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
in accordance with Section 2(a) hereof, or (E) the Company has breached Section 3(n) of this Agreement, or (F) trading in the Common Stock shall be suspended or if the Common Stock is no longer quoted on or is delisted from the
OTC Bulletin Board (or other principal exchange on which the Common Stock is traded) for any reason for more than three (3) 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 clauses (C) and (F) the date on which such three (3) Business Day period is exceeded, or for purposes of clause (D) after more than
fifteen (15) Business Days, being referred to as “Event Date”), the Company shall pay an amount in cash as liquidated damages to each Holder equal to two percent (2%) of the amount of the Holder’s initial investment
in the Preferred Stock for each calendar month or portion thereof thereafter from the Event Date until the applicable Event is cured; provided, however, that in no event shall the amount of liquidated damages payable at any time and
from time to time to any Holder pursuant to this Section 7(e) exceed an aggregate of twenty percent (20%) of the amount of the Holder’s initial investment in the Preferred Stock; and provided, further, that in the event
the Commission does not permit all of the Registrable Securities to be included in the Registration Statement because of its application of Rule 415, liquidated damages payable pursuant to this Section shall be payable by the Company based on two
percent (2%) of the portion of the Holder’s initial investment in the Preferred Stock that corresponds to the number of such Holder’s Registrable Securities permitted to be registered by the Commission in such Registration Statement
pursuant to Rule 415. Notwithstanding anything to the contrary in this paragraph (e), if (a) any of the Events described in clauses (A), (B), (C), (D) or (F) shall have 

  

 15 








 
occurred, (b) on or prior to the applicable Event Date, the Company shall have exercised its rights under Section 3(n) hereof and (c) 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. Liquidated damages payable by the Company pursuant to this Section 7(d) shall be payable on the first (1st) Business Day of each thirty (30) day period following the Event Date. Notwithstanding anything to the contrary contained herein, in no event shall any liquidated damages be payable with respect to the Warrants or the Warrant
Shares. 
 (f) 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 seventy-five percent
(75%) of the Registrable Securities outstanding. 
 (g) Notices. Any notice, demand, request, waiver or other
communication required or permitted to be given hereunder shall be in writing and shall be effective (a) upon hand delivery, telecopy or facsimile at the address or number designated below (if delivered on a business day during normal business
hours where such notice is to be received), or the first business day following such delivery (if delivered other than on a business day during normal business hours where such notice is to be received) or (b) on the second business day
following the date of mailing by express courier service, fully prepaid, addressed to such address, or upon actual receipt of such mailing, whichever shall first occur. The addresses for such communications shall be:

 (h) 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. 
 (i) 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 Person who acquires all or a portion of the Preferred Stock, the Common Shares or 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 unless such securities are registered in a Registration Statement under this Agreement (in which case the Company shall be
obligated to amend such Registration Statement to reflect such transfer or assignment) or are otherwise exempt from registration, (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.
The rights to assignment shall apply to the Holders (and to subsequent) successors and assigns. 
 (j) 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 and shall become effective when counterparts
have been signed by each party and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. 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. 
 (k) 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 

  

 17 








 
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(k) 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. 
 (l) Cumulative Remedies. The remedies provided herein are
cumulative and not exclusive of any remedies provided by law. 
 (m) 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. 
 (n) 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. 
 (o) 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. 
 (p) 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 action taken by any Purchaser pursuant hereto or thereto (including, but not limited to, the (i)

  

 18 








 
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 and each Purchaser acknowledges that for reasons of administrative convenience
only, the Transaction Documents have been prepared by counsel for one of the Purchasers and such counsel does not represent all of 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. The Company acknowledges that such procedure with respect to the Transaction Documents in no way creates a presumption
that the Purchasers are in any way acting in concert or as a group with respect to the Transaction Documents or the transactions contemplated hereby or thereby.

 Schedule II 
 Other Securities to be Included on the Registration Statement 
 See Schedule 2.1(c) to the Purchase
Agreement 
  

 II-1 








 Exhibit A 
 Plan of Distribution 
 The selling security holders and any of their pledgees, donees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares of common stock being offered under this prospectus on any stock exchange, market or trading facility on which shares of our common stock are traded or in private
transactions. These sales may be at fixed or negotiated prices. The selling security holders may use any one or more of the following methods when disposing of 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 resales by the broker-dealer for its account; 


  

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


  

	 	•	 	 privately negotiated transactions; 


  

	 	•	 	 to cover short sales made after the date that the registration statement of which this prospectus is a part is declared effective by the Commission;



  

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



 

	 	•	 	 a combination of any of these methods of sale; and 


  

	 	•	 	 any other method permitted pursuant to applicable law. 


 The shares may also be sold under Rule 144 under the Securities Act of 1933, as amended (“Securities Act”), if available, rather than under this prospectus. The selling security holders have the sole and
absolute discretion not to accept any purchase offer or make any sale of shares if they deem the purchase price to be unsatisfactory at any particular time. 
 The selling security holders may pledge their shares to their brokers under the margin provisions of customer agreements. If a selling security holder defaults on a margin loan, the broker may, from time to time,
offer and sell the pledged shares. 
 Broker-dealers engaged by the selling security holders may arrange for other broker-dealers to
participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, which commissions as to
a particular broker or dealer may be in excess of customary commissions to the extent permitted by applicable law. 
  

 A-1 








 If sales of shares offered under this prospectus are made to broker-dealers as principals, we would be
required to file a post-effective amendment to the registration statement of which this prospectus is a part. In the post-effective amendment, we would be required to disclose the names of any participating broker-dealers and the compensation
arrangements relating to such sales. 
 The selling security holders and any broker-dealers or agents that are involved in selling the shares
offered under this prospectus may be deemed to be “underwriters” within the meaning of the Securities Act in connection with these sales. Commissions received by these 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. Any broker-dealers or agents that are deemed to be underwriters may not sell shares offered under this prospectus unless and until we set forth the
names of the underwriters and the material details of their underwriting arrangements in a supplement to this prospectus or, if required, in a replacement prospectus included in a post-effective amendment to the registration statement of which this
prospectus is a part. 
 The selling security holders and any other persons participating in the sale or distribution of the shares offered
under this prospectus will be subject to applicable provisions of the Exchange Act, and the rules and regulations under that act, including Regulation M. These provisions may restrict activities of, and limit the timing of purchases and sales of any
of the shares by, the selling security holders or any other person. Furthermore, under Regulation M, persons engaged in a distribution of securities are prohibited from simultaneously engaging in market making and other activities with respect to
those securities for a specified period of time prior to the commencement of such distributions, subject to specified exceptions or exemptions. All of these limitations may affect the marketability of the shares. 
 If any of the shares of common stock offered for sale pursuant to this prospectus are transferred other than pursuant to a sale under this prospectus,
then subsequent holders could not use this prospectus until a post-effective amendment or prospectus supplement is filed, naming such holders. We offer no assurance as to whether any of the selling security holders will sell all or any portion of
the shares offered under this prospectus. 
 We have agreed to pay all fees and expenses we incur incident to the registration of the shares
being offered under this prospectus. However, each selling security holder and purchaser is responsible for paying any discounts, commissions and similar selling expenses they incur. 
 We and the selling security holders have agreed to indemnify one another against certain losses, damages and liabilities arising in connection with this
prospectus, including liabilities under the Securities Act.
