to the Purchaser an executed copy of this Subscription Agreement. If this subscription is rejected in whole or the Offering is

shall thereafter be of no further force or effect. If this subscription is rejected in part, the funds received by the Company
with respect to the rejected portion of this subscription, if any, will be returned without interest or offset, and this Subscription
Agreement will continue in full force and effect to the extent this subscription was accepted.

(e)          Since
the date of the Company’s most recent audited financial statements contained in a Form 10-K (a “Form 10-K”)
filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), there has been no material
adverse change and no material adverse development in the business, assets, liabilities, properties, operations (including results
thereof), condition (financial or otherwise) or prospects of the Company or any of its subsidiaries. Since the date of the Company’s
most recent audited financial statements contained in a Form 10-K, neither the Company nor any of its subsidiaries has (i) declared
or paid any dividends; (ii) sold any assets, individually or in the aggregate, outside of the ordinary course of business; or (iii)
made any capital expenditures, individually or in the aggregate, outside of the ordinary course of business. Neither the Company
nor any of its subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency,
reorganization, receivership, liquidation or winding up, nor does the Company or any subsidiary have any knowledge or reason to
believe that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of
any fact which would reasonably lead a creditor to do so. The Company and its subsidiaries, individually and on a consolidated
basis, are not as of the date hereof, and after giving effect to the transactions contemplated hereby to occur at such Closing,
will not be Insolvent (as defined below). For purposes of this Section 10(e), “Insolvent” means, (I)
with respect to the Company and its subsidiaries, on a consolidated basis; (a) the present fair saleable value of the Company’s
and its subsidiaries’ assets is less than the amount required to pay the Company’s and its subsidiaries’ total
indebtedness; (b) the Company and its subsidiaries are unable to pay their debts and liabilities, subordinated, contingent or otherwise,
as such debts and liabilities become absolute and matured; or (c) the Company and its subsidiaries intend to incur or believe that
they will incur debts that would be beyond their ability to pay as such debts mature; and (II) with respect to the Company and
each subsidiary, individually, (1) the present fair saleable value of the Company’s or such subsidiary’s (as the case
may be) assets is less than the amount required to pay its respective total indebtedness; (2) the Company or such subsidiary (as
the case may be) is unable to pay its respective debts and liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured; or (3) the Company or such subsidiary (as the case may be) intends to incur or believes
that it will incur debts that would be beyond its respective ability to pay as such debts mature. Neither the Company nor any of
its subsidiaries has engaged in any business or in any transaction, and is not about to engage in any business or in any transaction,
for which the Company’s or such subsidiary’s remaining assets constitute unreasonably small capital.


 


(f)          Other
than this Offering, no event, liability, development or circumstance has occurred or exists, or is reasonably expected to exist
or occur with respect to the Company, any of its subsidiaries or any of their respective businesses, properties, liabilities, prospects,
operations (including results thereof) or condition (financial or otherwise), that (i) would be required to be disclosed by the
Company under applicable securities laws on a registration statement on Form S-1 filed with the SEC relating to an issuance and
sale by the Company of its Common Stock and which has not been publicly announced; (ii) could have a material adverse effect on
any Purchaser’s investment hereunder; or (iii) could have a Material Adverse Effect. “Material Adverse Effect”
means any material adverse effect on (a) the business, properties, assets, liabilities, operations (including results thereof),
condition (financial or otherwise) or prospects of the Company or any subsidiary, individually or taken as a whole; (b) the transactions
contemplated hereby; or (c) the authority or ability of the Company or any of its subsidiaries to perform any of their respective
obligations under this Subscription Agreement or the Warrants.


 




    	-5- 



     


    

  


(g)          Neither
the Company, any of its subsidiaries or any director, officer, agent, employee, nor any other Person acting for or on behalf of
the foregoing (individually and collectively, a “Company Affiliate”) have violated the U.S. Foreign Corrupt
Practices Act or any other applicable anti-bribery or anti-corruption laws, nor has any Company Affiliate offered, paid, promised
to pay, or authorized the payment of any money, or offered, given, promised to give, or authorized the giving of anything of value,
to any officer, employee or any other person acting in an official capacity for any Government Entity, as defined below, to any
political party or official thereof or to any candidate for political office (individually and collectively, a “Government
Official”) or to any person under circumstances where such Company Affiliate knew or was aware of a high probability
that all or a portion of such money or thing of value would be offered, given or promised, directly or indirectly, to any Governmental
Official, for the purpose of: (i)(1) influencing any act or decision of such Government Official in his/her official capacity;
(2) inducing such Government Official to do or omit to do any act in violation of his/her lawful duty; (3) securing any improper
advantage; or (4) inducing such Government official to influence or affect any act or decision of any Government Entity; or (ii)
assisting the Company or its subsidiary in obtaining or retaining business for or with, or directing business to, the Company or
its subsidiary. “Government Entity” as used in the previous paragraph means any government or any department,
agency or instrumentality thereof, including any entity or enterprise owned or controlled by a government, or a public international
organization.


 


(h)          Neither
the Company nor any of its subsidiaries is a party to any collective bargaining agreement or employs any member of a union. The
Company believes that its and its subsidiaries’ relations with their respective employees are good. Other than with respect
to William Cotter, the Company’s former Chief Operating Officer who resigned from the Company effective June 15, 2015, no
executive officer (as defined in Rule 501(f) promulgated under the Securities Act) or other key employee of the Company or any
of its subsidiaries has notified the Company or any such subsidiary that such officer intends to leave the Company or any such
subsidiary or otherwise terminate such officer’s employment with the Company or any such subsidiary. No executive officer
or other key employee of the Company or any of its subsidiaries is, or is now expected to be, in violation of any material term
of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any
other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer or other key
employee (as the case may be) does not subject the Company or any of its subsidiaries to any liability with respect to any of the
foregoing matters. The Company and its subsidiaries are in compliance with all federal, state, local and foreign laws and regulations
respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except
where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material
Adverse Effect.


 




    	-6- 



     


    

  


(i)          It
is understood and acknowledged by the Company that (i) following the public disclosure of the transactions contemplated by this
Subscription Agreement in connection with the Form 8-K Filing, in accordance with the terms thereof, the Purchaser has not been
asked by the Company or any of its subsidiaries to agree, nor has the Purchaser agreed with the Company or any of its subsidiaries,
to desist from effecting any transactions in or with respect to (including, without limitation, purchasing or selling, long and/or
short) any securities of the Company, or “derivative” securities based on securities issued by the Company or to hold
any of the Securities for any specified term; (ii) the Purchaser, and counterparties in “derivative” transactions to
which the Purchaser is a party, directly or indirectly, presently may have a “short” position in the Common Stock which
was established prior to the Purchaser’s knowledge of the transactions contemplated by this Subscription Agreement; and (iii)
the Purchaser shall not be deemed to have any affiliation with or control over any arm’s length counterparty in any “derivative”
transaction. The Company further understands and acknowledges that following the public disclosure of the transactions contemplated
by this Subscription Agreement pursuant to the Form 8-K Filing, (a) the Purchaser may engage in hedging and/or trading activities
at various times during the period that the Securities are outstanding; and (b) such hedging and/or trading activities, if any,
can reduce the value of the existing stockholders’ equity interest in the Company both at and after the time the hedging
and/or trading activities are being conducted. The Company acknowledges that such aforementioned hedging and/or trading activities
do not constitute a breach of this Subscription Agreement or the Warrants or any of the documents executed in connection herewith
or therewith.


 


(j)          Neither
the Company nor any of its subsidiaries has, and, to the knowledge of the Company, no Person acting on their behalf has, directly
or indirectly, (i) taken any action designed to cause or to result in the stabilization or manipulation of the price of any security
of the Company or any of its subsidiaries to facilitate the sale or resale of any of the Securities; (ii) other than Maxim
Group LLC, sold, bid for, purchased, or paid any compensation for soliciting purchases of, any of the Securities; or (iii)
paid or agreed to pay to any Person other than Maxim Group LLC any compensation for soliciting
another to purchase any other securities of the Company or any of its subsidiaries.


 


(k)          Except
as disclosed in the Form 8-K Filing, the Company confirms that neither it nor any other Person acting on its behalf has provided
the Purchaser or its attorney, accountant, purchaser representative and/or tax adviser, if any (collectively, “Advisers”)
with any information that constitutes or could reasonably be expected to constitute material, non-public information concerning
the Company or any of its subsidiaries, other than the existence of the transactions contemplated by this Subscription Agreement.
The Company understands and confirms that the Purchaser will rely on the foregoing representations in effecting transactions in
securities of the Company. To the knowledge of the Company, all disclosure provided to the Purchaser regarding the Company and
its subsidiaries, their businesses and the transactions contemplated hereby, furnished by or on behalf of the Company or any of
its subsidiaries is true and correct and does not contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not
misleading. To the knowledge of the Company, each press release issued by the Company or any of its subsidiaries during the twelve
(12) months preceding the date of this Subscription Agreement did not at the time of release contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein,
in the light of the circumstances under which they are made, not misleading. To the knowledge of the Company, no event or circumstance
has occurred or information exists with respect to the Company or any of its subsidiaries or its or their business, properties,
liabilities, prospects, operations (including results thereof) or conditions (financial or otherwise), which, under applicable
law, rule or regulation, requires public disclosure at or before the date hereof or announcement by the Company but which has not
been so publicly disclosed. The Company acknowledges and agrees that the Purchaser does not make and has not made any representations
or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 11.

by the Company in the Offering and the Company may not use the proceeds effectively;


 


(d)          Restrictions
on Transfer or Sale of the Securities.


 


(1)         The
Purchaser is acquiring the Subscribed Units solely for such Purchaser’s own account and not with a view to or intent of resale
or distribution thereof, in whole or in part, in violation of the Securities Act. If and when the Purchaser exercises any Warrants,
the Purchaser will acquire the Warrant Shares solely for such Purchaser’s own account and not with a view to or intent of
resale or distribution thereof, in whole or in part, in violation of the Securities Act. The Purchaser has no agreement or arrangement,
formal or informal, with any person to sell or transfer all or any part of the Securities, and the Purchaser has no plans to enter
into any such agreement or arrangement;


 




    	-10- 



     


    

  


(2)         The
Purchaser understands that, except as provided in the Registration Rights Agreement (i) none of the Securities are registered under
the Securities Act, or any state securities laws; (ii) the offering and sale of the Units is intended to be exempt from registration
under the Securities Act by virtue of Section 4(a)(2) thereof based, in part, upon the representations, warranties and agreements
of the Purchaser contained in this Subscription Agreement; and (iii) consequently, the Securities may not be offered for sale,
sold, assigned or transferred unless (a) subsequently registered under the Registration Rights Agreement; (b) the Purchaser shall
have delivered to the Company (if requested by the Company) an opinion of counsel to the Purchaser, in a form reasonably acceptable
to the Company, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant
to an exemption from registration under the Securities Act; or (c) the Purchaser provides the Company with reasonable assurance
(which may include customary stockholder representation letters) that such Securities can be sold, assigned or transferred pursuant
to Rule 144 promulgated under the Securities Act;


 


(3)         The
Purchaser understands that (i) it must bear the substantial economic risks of the investment in the Subscribed Units indefinitely
because none of the Securities may be sold, hypothecated or otherwise disposed of unless subsequently registered under the Securities
Act and applicable state securities laws or an exemption from such registration is available; (ii) legends shall be placed on the
certificates representing the Common Stock and the Warrants included in the Subscribed Units and any Warrant Shares issued upon
exercise of the Warrants to the effect that they have not been registered under the Securities Act or applicable state securities
laws and appropriate notations thereof will be made in the Company’s books and records; (iii) stop transfer instructions
will be placed with any registrar or transfer agent of the Common Stock and the Warrants, if other than the Company; and (iv) there
can be no assurance any market will ever exist for resale of any of the Securities, nor can there be any assurance that any of
such Securities will be freely transferable at any time in the foreseeable future;


 


(e)          Status
of Purchaser.


 


(1)         The
Purchaser is an “accredited investor” as that term is defined under Rule 501(a) of Regulation D because the Purchaser
meets the requirements of at least one of the suitability standards for an “accredited investor” as that term is defined
in Regulation D and as set forth on the Accredited Investor Certification contained herein;


 


(2)         Neither
the Purchaser, nor any of its affiliates, nor any person claiming by or through any of them, is subject to any “bad actor”
disqualification specified in Rule 506(d) of Regulation D (a “Disqualification Event”). The Purchaser undertakes
to update the Company in the event that the Purchaser (or any of its affiliates, or any person claiming by or through any of them)
subsequently becomes subject to a Disqualification Event;


 


(3)         The
Purchaser, together with its Advisers, if any, has such knowledge and experience in financial, tax, and business matters, and,
in particular, investments in securities, so as to enable it to utilize the information made available to it in connection with
the Offering to evaluate the merits and risks of an investment in the Units and the Company and to make an informed investment
decision with respect thereto;


 




    	-11- 



     


    

  


(4)         The
Purchaser has significant prior investment experience, including investment in non-listed and non-registered securities. The Purchaser
is knowledgeable about investment considerations in development-stage companies with limited operating histories. The Purchaser
has a sufficient net worth to sustain a loss of its entire investment in the Company in the event such a loss should occur. The
Purchaser’s overall commitment to investments which are not readily marketable is not excessive in view of the Purchaser’s
net worth and financial circumstances and the purchase of the Subscribed Units will not cause such commitment to become excessive.
The investment is a suitable one for the Purchaser;


 


(5)         The
Purchaser has adequate means of providing for such Purchaser’s current financial needs and foreseeable contingencies and
has no need for liquidity from its investment in the Units for an indefinite period of time;


 


12.         Covenants.


 


(a)          Additional

option or right to purchase, or otherwise dispose of (or announce any issuance, offer, sale, grant of any option or right to purchase
or other disposition of) any equity security or any equity-linked or related security (including, without limitation, any “equity

debt, any preferred stock or any purchase rights (any such issuance, offer, sale, grant, disposition or announcement (whether occurring

the foregoing, this Section 12(a) shall not apply in respect of the issuance of (A) shares of Common Stock or options to

an “Investor”); (B) shares of Common Stock issued upon the conversion, exercise or exchange of Convertible Securities
(other than options to purchase Common Stock or such other equity awards issued pursuant to an Approved Share Plan that are covered

prior to the date of this Subscription Agreement, the conversion, exercise or exchange price of any such Convertible Securities
(other than options to purchase Common Stock or such other equity awards issued pursuant to an Approved Share Plan that are covered
by clause (A) above) is not lowered, none of such Convertible Securities are (other than options to purchase Common Stock or such
other equity awards issued pursuant to an Approved Share Plan that are covered by clause (A) above)(nor is any provision of any
such Convertible Securities) amended or waived in any manner (whether by the Company or the holder thereof) to increase, or which
results in an increase in, the number of shares issuable thereunder and none of the terms or conditions of any such Convertible
Securities (other than options to purchase Common Stock or such other equity awards issued pursuant to an Approved Share Plan that
are covered by clause (A) above) are otherwise materially changed or waived (whether by the Company or the holder thereof) in any
manner that adversely affects any of the Purchasers; (C) the Warrants; (D) the Warrant Shares; (E) shares of Common Stock issued
in connection with acquisitions, asset purchases, licenses, collaborations or strategic transactions involving the Company and
other Persons approved by the Company’s board of directors; provided that any such issuance shall only be to Strategic
Entity and shall provide to the Company additional benefits in addition to the investment of funds, and shall not include a transaction
in which the Company is issuing Common Stock or any other security primarily for the purpose of raising capital or to an entity
whose primary business is investing in securities; and (F) shares of Common Stock issued to a Stategic Entity; provided that
the Company’s board of directors reasonable determines that such issuance shall provide to the Company additional benefits
in addition to the investment of funds (each of the foregoing in clauses (A) through (F), collectively the “Excluded Securities”).
For purposes of this Subscription Agreement, (1) “Applicable Date” means the first date on which the resale

in their capacity as such including, but not limited to, the Company’s 2013 Stock Incentive Plan; (3) “Convertible
Securities” means any capital stock, note, debenture or other security of the Company or any of its subsidiaries that
is, or may become, at any time and under any circumstances directly or indirectly convertible into, exercisable or exchangeable
for, or which otherwise entitles the holder thereof to acquire, any capital stock, note, debenture or other security of the Company
(including, without limitation, Common Stock) or any of its subsidiaries; and (4) “Strategic Entity” means a

(b)          Participation
Right. From the date hereof through the six (6) month anniversary of the Applicable Date, neither the Company nor any of its
subsidiaries shall, directly or indirectly, effect any Subsequent Placement unless the Company shall have first complied with this
Section 12(b).


 




    	-12- 



     


    

  


(1)         At
least three (3) Business Days prior to any proposed or intended Subsequent Placement, the Company shall deliver to each Investor
a written notice of its proposal or intention to effect a Subsequent Placement (each such notice, a “Pre-Notice”),
which Pre-Notice shall not contain any information other than: (i) a statement that the Company proposes or intends to effect a
Subsequent Placement, and (ii) a statement informing such Investor that it is entitled to receive an Offer Notice (as defined below)
with respect to such Subsequent Placement upon its written request. Upon the written request of a Investor within two (2) Business
Days after the Company’s delivery to such Investor of such Pre-Notice, and only upon a written request by such Investor,
the Company shall promptly, but no later than one (1) Business Day after such request, deliver to such Investor an irrevocable
written notice (the “Offer Notice”) of any proposed or intended issuance or sale or exchange (the “Offer”)
of the securities being offered (the “Offered Securities”) in a Subsequent Placement, which Offer Notice shall
(w) identify and describe the Offered Securities, (x) describe the price and other terms upon which they are to be issued, sold
or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (y) identify the Persons (if
known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged ; and (z) offer to issue and
sell to or exchange with such Investor in accordance with the terms of the Offer, Offered Securities with an aggregate purchase
price equal to such Investor’s Pro-Rata Share. For purposes of this Subscription Agreement, (1) “Pro Rata Share”
means, with respect to each Investor, a dollar amount equal to (I) the Investor Allocation multiplied by a fraction, the numerator
of which shall be the number Units purchased by such Investor in the Offering, and the denominator of which shall be the aggregate
number of Units purchased in the Offering by all Investors (such product, the Investor’s “Basic Amount”);
and (II) with respect to an Investor that elects to purchase its Basic Amount, any additional portion of the Offered Securities
attributable to the Basic Amounts of other Investors as such Investor shall indicate it will purchase or acquire should the other
Investors subscribe for less than their Basic Amounts (the “Undersubscription Amount”); and (2) “Investor
Allocation” means the lesser of (A) fifty percent (50%) of the aggregate value of the Offered Securities, and (B) the
aggregate purchase price of all Units purchased in the Offering.


 


(2)         To
accept an Offer, in whole or in part, such Investor must deliver a written notice to the Company prior to the end of the fifth
(5th) Business Day after such Investor’s receipt of the Offer Notice (the “Offer Period”),
setting forth the portion of such Investor’s Basic Amount that such Investor elects to purchase and, if such Investor shall
elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Investor elects to purchase (in either
case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Investors are less than the total
of all of the Basic Amounts, then such Investor who has set forth an Undersubscription Amount in its Notice of Acceptance shall
be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided,
however, if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and
the Basic Amounts subscribed for (the “Available Undersubscription Amount”), such Investor who has subscribed
for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the
Basic Amount of such Investor bears to the total Basic Amounts of all Investors that have subscribed for Undersubscription Amounts,
subject to rounding by the Company to the extent it deems reasonably necessary. Notwithstanding the foregoing, if the Company desires
to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to
such Investor a new Offer Notice and the Offer Period shall expire on the fifth (5th) Business Day after such Investor’s
receipt of such new Offer Notice.


 




    	-13- 



     


    

  


(3)         The
Company shall have five (5) Business Days from the expiration of the Offer Period above (i) to offer, issue, sell or exchange all
or any part of such Offered Securities as to which a Notice of Acceptance has not been given by a Investor (together with the remaining
portion the Offered Securities that were not offered to the Investors pursuant to Section 12(b)(1), the “Refused
Securities”) pursuant to a definitive agreement(s) (the “Subsequent Placement Agreement”), but only
to the offerees described in the Offer Notice (if so described therein) and only upon terms and conditions (including, without
limitation, unit prices and interest rates) that are not more favorable to the acquiring Person or Persons or less favorable to
the Company than those set forth in the Offer Notice; and (ii) to publicly announce (a) the execution of such Subsequent Placement
Agreement, and (b) either (x) the consummation of the transactions contemplated by such Subsequent Placement Agreement or (y) the
termination of such Subsequent Placement Agreement, which shall be filed with the SEC on a Current Report on Form 8-K with such
Subsequent Placement Agreement and any documents contemplated therein filed as exhibits thereto.


 


(4)         In
the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the
terms specified in Section 12(b)(3) above), then such Investor may, at its sole option and in its sole discretion, reduce
the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the
number or amount of the Offered Securities that such Investor elected to purchase pursuant to Section 12(b)(2) above multiplied
by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to
issue, sell or exchange (including Offered Securities to be issued or sold to Investors pursuant to this Section 12(b) prior
to such reduction); and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that
any Investor so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company
may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities
have again been offered to the Investors in accordance with Section 12(b)(1) above.


 


(5)         Upon
the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, such Investor shall acquire from
the Company, and the Company shall issue to such Investor, the number or amount of Offered Securities specified in its Notice of
Acceptance. Subject to Section 12(b)(7), the purchase by such Investor of any Offered Securities shall be made on the same
terms and conditions and subject to the same Subsequent Placement Agreement entered into between the Company and the purchasers
of the Refused Securities.


 


(6)         Any
Offered Securities not acquired by an Investor or other Persons in accordance with this Section 12(b) may not be issued,
sold or exchanged until they are again offered to such Investor under the procedures specified in this Subscription Agreement.


 


(7)         The
Company and the Purchaser agree that if any Investor elects to participate in the Offer, neither the Subsequent Placement Agreement
with respect to such Offer nor any other transaction documents related thereto (collectively, the “Subsequent Placement
Documents”) shall include any term or provision whereby such Investor shall be required to agree to any restrictions
on trading as to any securities of the Company (other than restrictions required by applicable securities laws on the resale of
the specific “restricted securities” (as that term is defined under Rule 144) being issued in the Subsequent Placement)
or be required to consent to any amendment to or termination of, or grant any waiver, release or the like under or in connection
with, any agreement previously entered into with the Company or any instrument received from the Company.


 




    	-14- 



     


    

  


(8)         Notwithstanding
anything to the contrary in this Section 12(b) and unless otherwise agreed to by such Investor, the Company shall either
confirm in writing to such Investor that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly
disclose its intention to issue the Offered Securities, in either case, in such a manner such that such Investor will not be in
possession of any material, non-public information regarding the Company or any of its subsidiaries, by the fifth (5th)
Business Day following expiration of the Offer Period. If by such fifth (5th) Business Day, no public disclosure regarding
a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such transaction
has been received by such Investor, such transaction shall be deemed to have been abandoned and such Investor shall not be in possession
of any material, non-public information regarding the Company or any of its subsidiaries. Should the Company decide to pursue such
transaction with respect to the Offered Securities, the Company shall provide such Investor with another Offer Notice in accordance
with, and subject to, the terms of this Section 12(b) and such Investor will again have the right of participation set forth
in this Section 12(b). The Company shall not be permitted to deliver more than one Offer Notice to such Investor in any
sixty (60) day period, except as expressly contemplated by the last sentence of Section 12(b)(2).


 


(9)         The
restrictions contained in this Section 12(b) shall not apply in connection with the issuance of any Excluded Securities.
The Company shall not circumvent the provisions of this Section 12(b) by providing terms or conditions to one Investor that
are not provided to all Investors.


 


(c)          Variable
Rate Transaction. Beginning on the date hereof and until the earlier of (a) the nine (9) month anniversary of the Applicable
Date; and (b) the date on which all of the Investors shall have sold all of the Registrable Securities, the Company and each subsidiary
shall be prohibited from effecting or entering into an agreement to effect any Subsequent Placement involving a Variable Rate Transaction
(it being expressly understood and agreed that the foregoing shall not prohibit the Company from consummating the transactions
contemplated by this Agreement). “Variable Rate Transaction” means a transaction in which the Company or any
subsidiary (i) issues or sells any Convertible Securities either (A) at a conversion, exercise 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 Convertible 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 Convertible Securities 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, other than pursuant to
a customary “weighted average” anti-dilution provision; or (ii) enters into any agreement (including, without limitation,
an “equity line of credit” or an “at-the-market offering”) whereby the Company or any subsidiary may sell
securities at a future determined price (other than standard and customary “preemptive” or “participation”
rights). Each Investor shall be entitled to obtain injunctive relief against the Company and its subsidiaries to preclude any such
issuance, which remedy shall be in addition to any right to collect damages.


 




    	-15- 



     


    

  


13.         Indemnification
of Purchaser. Subject to the provisions of this Section 13, the Company will indemnify and hold Purchaser and its directors,
officers, shareholders, members, partners, employees and agents (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), 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 Subscription 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 Parties, with respect to any of the transactions contemplated by the Transaction Documents
(unless such action is based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction
Documents or any agreements or understandings such Purchaser Parties may have with any such stockholder or any violations by such
Purchaser Parties of state or federal securities laws or any other conduct by such Purchaser Parties which constitutes fraud, gross
negligence, willful misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect of which
indemnity may be sought pursuant to this Subscription 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 such separate 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 Subscription 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 Subscription Agreement
or in the other Transaction Documents. The indemnification required by this Section 13 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.
