of any Subsidiary. The issuance and sale of the Securities will not obligate the Company or any Subsidiary to issue shares of
Common Stock or other securities to any Person (other than the Purchasers) and will not result in a right of any holder of Company
securities to adjust the exercise, conversion, exchange or reset price under any of such securities. There are no outstanding
securities or instruments of the Company or any Subsidiary that contain any redemption or similar provisions, and there are no
contracts, commitments, understandings or arrangements by which the Company or any Subsidiary is or may become bound to redeem
a security of the Company or such Subsidiary. The Company does not have any stock appreciation rights or “phantom stock”
plans or agreements or any similar plan or agreement. All of the outstanding shares of capital stock of the Company are duly authorized,
validly issued, fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and none
of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities.
No further approval or authorization of any stockholder, the Board of Directors or others is required for the issuance and sale
of the Securities. There are no stockholders agreements, voting agreements or other similar agreements with respect to the Company’s
capital stock to which the Company is a party or, to the knowledge of the Company, between or among any of the Company’s
stockholders.

be paid. Except as set forth on Schedule 3.1 (aa) , the Company does not intend to incur debts beyond its ability to pay
such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). Except

3.2
Representations and Warranties of the Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents
and warrants as of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein,
in which case they shall be accurate as of such date):


 


(a)
Organization; Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing
and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership,
limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by the
Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction
Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized
by all necessary corporate, partnership, limited liability company or similar action, as applicable, on the part of such Purchaser.
Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser
in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against
it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii)
as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii)
insofar as indemnification and contribution provisions may be limited by applicable law.


 




    	 	23	 



     


    

 


(b)
Understandings or Arrangements. Such Purchaser is acquiring the Securities as principal for its own account and has no
direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities
(this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the Registration
Statement or otherwise in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Securities
hereunder in the ordinary course of its business.


 


(c)
Purchaser Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on
each date on which it exercises any Warrants or converts any shares of Preferred Stock it will be an “accredited investor”
as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act.


 


(d)
Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication
and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is able to bear the economic risk
of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.


 


(e)
Access to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction Documents
(including all exhibits and schedules thereto) and the SEC Reports and has been afforded, (i) the opportunity to ask such questions
as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions
of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the
Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable
it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can
acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment.
Such Purchaser acknowledges and agrees that neither the Placement Agent nor any Affiliate of the Placement Agent has provided
such Purchaser with any information or advice with respect to the Securities nor is such information or advice necessary or desired.
Neither the Placement Agent nor any Affiliate has made or makes any representation as to the Company or the quality of the Securities
and the Placement Agent and any Affiliate may have acquired non-public information with respect to the Company which such Purchaser
agrees need not be provided to it. In connection with the issuance of the Securities to such Purchaser, neither the Placement
Agent nor any of its Affiliates has acted as a financial advisor or fiduciary to such Purchaser.


 




    	 	24	 



     


    

 


(f)
Certain Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser
has not directly or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, executed
any purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that
such Purchaser first received a term sheet (written or oral) from the Company or any other Person representing the Company setting
forth the material pricing terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof.
Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio
managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the
investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation
set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment
decision to purchase the Securities covered by this Agreement. Other than to other Persons party to this Agreement or to such
Purchaser’s representatives, including, without limitation, its officers, directors, partners, legal and other advisors,
employees, agents and Affiliates, such Purchaser has maintained the confidentiality of all disclosures made to it in connection
with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for the avoidance
of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to locating
or borrowing shares in order to effect Short Sales or similar transactions in the future.


 


The
Company acknowledges and agrees that the representations contained in this Section 3.2 shall not modify, amend or affect such
Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations
and warranties contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection
with this Agreement or the consummation of the transactions contemplated hereby. Notwithstanding the foregoing, for the avoidance
of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to locating
or borrowing shares in order to effect Short Sales or similar transactions in the future.

4.1
Underlying Shares. The shares of Common Stock underlying the shares of Preferred Stock shall be issued free of legends.
If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the issuance
or resale of the Warrant Shares or if the Warrant is exercised via cashless exercise, the Warrant Shares issued pursuant to any
such exercise shall be issued free of all legends. If at any time following the date hereof the Registration Statement (or any
subsequent registration statement registering the sale or resale of the Warrant Shares) is not effective or is not otherwise available
for the sale or resale of the Warrant Shares, the Company shall immediately notify the holders of the Warrants in writing that
such registration statement is not then effective and thereafter shall promptly notify such holders when the registration statement
is effective again and available for the sale or resale of the Warrant Shares (it being understood and agreed that the foregoing
shall not limit the ability of the Company to issue, or any Purchaser to sell, any of the Warrant Shares in compliance with applicable
federal and state securities laws). The Company shall use best efforts to keep a registration statement (including the Registration

    	 	25	 



     


    

 


4.2
Acknowledgment of Dilution. The Company acknowledges that the issuance of the Securities may result in dilution of the
outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges
that its obligations under the Transaction Documents, including, without limitation, its obligation to issue the Underlying Shares
pursuant to the Transaction Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay
or reduction, regardless of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless
of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company.


 


4.3
Furnishing of Information; Public Information. Until the earliest of the time that (i) no Purchaser owns Securities or
(ii) the Warrants have expired, the Company covenants to maintain the registration of the Common Stock under Section 12(b) or

Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any
security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities for

of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.


 


4.5
Conversion and Exercise Procedures. Each of the form of Notice of Exercise included in the Warrants and the form of Notice
of Conversion included in the Certificate of Designation set forth the totality of the procedures required of the Purchasers in
order to exercise the Warrants or convert the Preferred Stock. Without limiting the preceding sentences, no ink-original Notice
of Exercise or Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization)
of any Notice of Exercise or Notice of Conversion form be required in order to exercise the Warrants or convert the Preferred
Stock. No additional legal opinion, other information or instructions shall be required of the Purchasers to exercise their Warrants
or convert their Preferred Stock. The Company shall honor exercises of the Warrants and conversions of the Preferred Stock and
shall deliver Underlying Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

4.6
Securities Laws Disclosure; Publicity. The Company shall (a) by 9:00 a.m. (New York City time) on the Trading Day immediately
following the date hereof, issue a press release disclosing the material terms of the transactions contemplated hereby, and (b)

it shall have publicly disclosed all material, non-public information delivered to any of the Purchasers by the Company or any
of its Subsidiaries, or any of their respective officers, directors, employees or agents in connection with the transactions contemplated
by the Transaction Documents. In addition, effective upon the issuance of such press release, the Company acknowledges and agrees
that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any
of its Subsidiaries or any of their respective officers, directors, agents, employees or Affiliates on the one hand, and any of
the Purchasers or any of their Affiliates on the other hand, shall terminate. The Company and each Purchaser shall consult with
each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor
any Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of the
Company, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any
press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required
by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or
communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the
name of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written
consent of such Purchaser, except: (a) as required by federal securities law in connection with the filing of final Transaction
Documents with the Commission and (b) to the extent such disclosure is required by law or Trading Market regulations, in which
case the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b).


 


4.7
Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other
Person, that any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison

adopted by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue
of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers.


 


4.8
Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the
Transaction Documents, which shall be disclosed pursuant to Section 4.6, the Company covenants and agrees that neither it, nor
any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that constitutes,
or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have
consented to the receipt of such information and agreed with the Company to keep such information confidential. The Company understands
and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.
To the extent that the Company delivers any material, non-public information to a Purchaser without such Purchaser’s consent,
the Company hereby covenants and agrees that such Purchaser shall not have any duty of confidentiality to the Company, any of
its Subsidiaries, or any of their respective officers, directors, agents, employees or Affiliates, or a duty to the Company, or
any of its Subsidiaries or any of their respective officers, directors, agents, employees or Affiliates not to trade on the basis
of, such material, non-public information, provided that the Purchaser shall remain subject to applicable law. To the extent that
any notice provided pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding
the Company or any Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report
on Form 8-K. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting

equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls
such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors,
officers, shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a
Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser
Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses,
including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation
that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations,
warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action
instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of
the Company who is not an Affiliate of such Purchaser Party, with respect to any of the transactions contemplated by the Transaction
Documents (unless such action is solely based upon a material breach of such Purchaser Party’s representations, warranties
or covenants under the Transaction Documents or any agreements or understandings such Purchaser Party may have with any such stockholder
or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party which is
finally judicially determined to constitute fraud, gross negligence or willful misconduct). If any action shall be brought against
any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly
notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing
reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser
Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the
Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there
is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the
position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more
than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement
by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed;
or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s
breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in
the other Transaction Documents. The indemnification required by this Section 4.10 shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements
contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others
and any liabilities the Company may be subject to pursuant to law.

4.11
Reservation and Listing of Securities.


 


(a)
As of the date hereof, the Company has reserved, and the Company shall continue to reserve and keep available at all times, free
of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares pursuant
to this Agreement, Conversion Shares pursuant to any conversion of the Preferred Stock and Warrant Shares pursuant to any exercise
of the Warrants.


 


(b)
If, on any date, the number of authorized but unissued (and otherwise unreserved) shares of Common Stock is less than the Required
Minimum on such date, then the Board of Directors shall use commercially reasonable efforts to amend the Company’s certificate
or articles of incorporation to increase the number of authorized but unissued shares of Common Stock to at least the Required

or quotation and (iv) maintain the listing or quotation of such Common Stock on any date at least equal to the Required Minimum
on such date on such Trading Market or another Trading Market. The Company agrees to maintain the eligibility of the Common Stock

4.13
Subsequent Equity Sales.


 


(a)
From the date hereof until 90 days after the Closing Date, neither the Company nor any Subsidiary shall issue, enter into any
agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents.


 


(b)
From the date hereof until the two year anniversary of the Closing Date, the Company shall be prohibited from effecting or entering
into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents
(or a combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means
a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or
exercisable for, or include the right to receive, additional shares of Common Stock either (A) at a conversion price, exercise
price or exchange rate or other price that is based upon, and/or varies with, the trading prices of or quotations for the shares
of Common Stock at any time after the initial issuance of such debt or equity securities or (B) with a conversion, exercise or
exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or
upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market
for the Common Stock or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity
line of credit, whereby the Company may issue securities at a future determined price. Any Purchaser shall be entitled to obtain
injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect
damages.


 


(c)
Notwithstanding the foregoing, this Section 4.13 shall not apply in respect of an Exempt Issuance, except that no Variable Rate
Transaction shall be an Exempt Issuance.


 


4.14
Equal Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered
or paid to any Person to amend or consent to a waiver or modification of any provision of the Transaction Documents unless the
same consideration is also offered to all of the parties to such Transaction Documents. For clarification purposes, this provision
constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended
for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or
as a group with respect to the purchase, disposition or voting of Securities or otherwise.

4.15
Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants
that neither it, nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or
sales, including Short Sales, of any of the Company’s securities during the period commencing with the execution of this
Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to
the initial press release as described in Section 4.6. Each Purchaser, severally and not jointly with the other Purchasers, covenants
that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the
initial press release as described in Section 4.6, such Purchaser will maintain the confidentiality of the existence and terms
of this transaction and the information included in the Disclosure Schedules. Notwithstanding the foregoing, and notwithstanding
anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes
any representation, warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company
after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press
release as described in Section 4.6, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any
securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated
by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.6 and (iii) no
Purchaser shall have any duty of confidentiality or duty not to trade in the securities of the Company to the Company or its Subsidiaries
after the issuance of the initial press release as described in Section 4.6. Notwithstanding the foregoing, in the case of a Purchaser
that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s
assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing
other portions of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of
assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement.

of the Securities, based on the initial Subscription Amounts hereunder, or, in the case of a waiver, by the party against whom
enforcement of any such waived provision is sought, provided that if any amendment, modification or waiver disproportionately
and adversely impacts a Purchaser (or group of Purchasers), the consent of such disproportionately impacted Purchaser (or group

Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other

and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If any party shall commence
an Action or Proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company
under Section 4.10, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for its
reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of
such Action or Proceeding.


 


5.10
Survival. The representations and warranties contained herein shall survive the Closing and the delivery of the Securities.


 


5.11
Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other
party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by
facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if
such facsimile or “.pdf” signature page were an original thereof.

5.12
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 commercially 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.


 


5.13
Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar
provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under
a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then
such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant
notice, demand or election in whole or in part without prejudice to its future actions and rights; provided, however,
that in the case of a rescission of a conversion of the Preferred Stock or exercise of a Warrant, the applicable Purchaser shall
be required to return any shares of Common Stock subject to any such rescinded conversion or exercise notice concurrently with
the return to such Purchaser of the aggregate exercise price paid to the Company for such shares and the restoration of such Purchaser’s
right to acquire such shares pursuant to such Purchaser’s Warrant (including, issuance of a replacement warrant certificate
evidencing such restored right).


 


5.14
Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed,
the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation),
or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory
to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances
shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement
Securities.


 


5.15
Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of
damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The
parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations
contained in the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any
such obligation the defense that a remedy at law would be adequate.

5.16
Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction
Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement
or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered
from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other
Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of
action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be
revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.


 


5.17
Usury. To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plead or in any manner whatsoever
claim, and will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now
or at any time hereafter in force, in connection with any Action or Proceeding that may be brought by any Purchaser in order to
enforce any right or remedy under any Transaction Document. Notwithstanding any provision to the contrary contained in any Transaction
Document, it is expressly agreed and provided that the total liability of the Company under the Transaction Documents for payments
in the nature of interest shall not exceed the maximum lawful rate authorized under applicable law (the “Maximum Rate”),
and, without limiting the foregoing, in no event shall any rate of interest or default interest, or both of them, when aggregated
with any other sums in the nature of interest that the Company may be obligated to pay under the Transaction Documents exceed
such Maximum Rate. It is agreed that if the maximum contract rate of interest allowed by law and applicable to the Transaction
Documents is increased or decreased by statute or any official governmental action subsequent to the date hereof, the new maximum
contract rate of interest allowed by law will be the Maximum Rate applicable to the Transaction Documents from the Closing Date
thereof forward, unless such application is precluded by applicable law. If under any circumstances whatsoever, interest in excess
of the Maximum Rate is paid by the Company to any Purchaser with respect to indebtedness evidenced by the Transaction Documents,
such excess shall be applied by such Purchaser to the unpaid principal balance of any such indebtedness or be refunded to the
Company, the manner of handling such excess to be at such Purchaser’s election.


 


5.18
Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction
Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way
for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained
herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed
to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption
that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated
by the Transaction Documents. 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. Each Purchaser has been represented
by its own separate legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience
only, each Purchaser and its respective counsel have chosen to communicate with the Company through EGS. EGS does not represent
any of the Purchasers and only represents the Placement Agent. The Company 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 any
of the Purchasers. It is expressly understood and agreed that each provision contained in this Agreement and in each other Transaction
Document is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between
and among the Purchasers.

5.19
Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under
the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated
damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial
liquidated damages or other amounts are due and payable shall have been canceled.


 


5.20
Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right
required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next
succeeding Business Day.


 


5.21
Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity
to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to
be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments
thereto. In addition, each and every reference to share prices and shares of Common Stock in any Transaction Document shall be
subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions
of the Common Stock that occur after the date of this Agreement.


 


5.22
WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER
PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY,
IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
