agrees to purchase from Arch Therapeutics, Inc., a Nevada corporation (the “Company”), the principal amount
of the Company’s 8% Convertible Notes due 2016 (the (“Notes”), in the form of Exhibit A

This Subscription Agreement (this “Subscription Agreement”) is one in a series of similar subscription agreements
expected to be entered into pursuant to the Offering. No closing of the Offering shall occur unless a minimum of $750,000 in aggregate
principal amount of the Notes has been sold in the Offering.

at a closing (the “Closing”), to occur on or before March 13, 2015 (the “Closing Date”).
At the Closing, the Company shall issue and sell to the Purchaser and the Purchaser shall purchase from the Company the Notes being
subscribed for by the Purchaser hereunder. On or before the Closing, the Purchaser shall make a wire transfer payment in the full
amount of the purchase price for the Notes for which the Purchaser is subscribing in this Subscription Agreement to be purchased
on the Closing to an account specified in writing by the Company. The funds wired by the Purchaser will be held by the Company
in a non-interest-bearing account until the earliest to occur of (a) the Closing Date and (b) the rejection of this subscription
by the Company. No escrow account will be established or maintained in connection with the Offering.

the right to accept or reject this subscription or any other subscription for Notes, in whole or in part, notwithstanding prior
receipt by the Purchaser of notice of acceptance of this subscription. The Company shall have no obligation hereunder until the
Company executes and delivers to the Purchaser an executed copy of this Subscription Agreement. If this subscription is rejected
in whole or the Offering is terminated, all funds received from the Purchaser will be returned without interest or offset, and
this Subscription Agreement shall thereafter be of no further force or effect. If this subscription is rejected in part, the funds
for the rejected portion of this subscription will be returned without interest or offset, and this Subscription Agreement will

Shares will not (i) result in a violation of the Charter (as defined below) (including, without limitation, any certificates of
designation contained therein) or other organizational documents of the Company or any of its Subsidiaries, any capital stock of
the Company, or Bylaws (as defined below), (ii) conflict with, or constitute a default (or an event which with notice or lapse

 The Company is not required to obtain any consent from, authorization or order of, or make any filing or registration with
any court, governmental agency or any regulatory or self-regulatory agency or any other Person in order for it to execute, deliver
or perform any of its obligations under, or contemplated by, the Transaction Documents, in each case, in accordance with the terms

and has no knowledge of any facts or circumstances which could reasonably lead to delisting or suspension of the Common Stock therefrom

(e)               
Since the date of the Company’s most recent audited financial statements contained in a Form 10-K filed under the
Securities Exchange Act of 1934 (a “Form 10-K”), 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

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

are unable to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute
and matured or (iii) 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, (i) 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, (ii) 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 (iii)
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)               
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 (i) 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, (ii) the transactions contemplated
hereby or (iii) the authority or ability of the Company or any of its Subsidiaries to perform any of their respective obligations
under this Agreement or the Warrants.

 

(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. No executive
officer (as defined in Rule 501(f) promulgated under the 1933 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.

 

(i)                
It is understood and acknowledged by the Company that (i) following the public disclosure of the transactions contemplated
by this Agreement in connection with the Form 8-K Filing (as defined below), 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 any 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 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 Agreement pursuant to the Form 8-K Filing, 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 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) sold,
bid for, purchased, or paid any compensation for soliciting purchases of, any of the Securities (other than the Placement Agent),
or (iii) paid or agreed to pay to any Person 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 their agents or counsel 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 Agreement. The Company understands and confirms that the Purchaser will rely on the foregoing
representations in effecting transactions in securities 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. Each press release issued by the Company or any of its Subsidiaries during the twelve (12) months preceding the
date of this 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. 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 5.

 

7.             Press Release and Form 8-K. The Company and the Purchaser agree that the Company shall issue a press release and

the Purchaser 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 this Agreement. The Company shall not, and the Company shall cause each of its
Subsidiaries and each of its and their respective officers, directors, employees and agents not to, provide the Purchaser with
any material, non-public information regarding the Company or any of its Subsidiaries from and after the Form 8-K Filing without
the express prior written consent of such Purchaser.

 

8.             Modification. This Subscription Agreement shall not be modified or waived except by an instrument in writing signed
by the party against whom any such modification or waiver is sought.

courts of New York located in New York county and to the jurisdiction of the United States District Court for the Southern District
of New York for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (b) agree not
to commence any suit, action or other proceeding arising out of or based upon this Agreement except in such courts, and (c) hereby
waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim
that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment
or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding
is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

Offering or any issuance of Conversion Shares under the securities laws of any jurisdiction.

4.             Conversion
Rights.

 

(a)               
Subject to and upon compliance with the provisions of this Note, prior to the Stated Maturity Date, the Holder shall have
the right, at its option at any time, to convert some or all of the Note into such number of fully paid and nonassessable shares
of Common Stock as is obtained by: (i) adding (A) the principal amount of this Note to be converted and (B) the amount of any accrued
but unpaid interest with respect to such portion of this Note to be converted; and (ii) dividing the result obtained pursuant to
clause (i) above by the Conversion Price then in effect. The rights of conversion set forth in this Section 4 shall be exercised
by the Holder by giving written notice to the Company that the Holder elects to convert a stated amount of this Note into Common
Stock to the Company by email or facsimile at its principal office (or such other office or agency of the Company as the Company
may designate by notice in writing to the Holder) at any time on the date set forth in such notice (which date shall not be earlier
than the Company’s receipt of such notice), together with a statement of the name or names (with address) in which the certificate
or certificates for shares of Common Stock shall be issued.

 

(b)              
Promptly after receipt of the written notice referred to in Section 4(a) above and surrender of this Note (or, in lieu thereof,
by delivery of an appropriate lost security affidavit in the event this Note shall have been lost or destroyed), but in no event
more than three (3) Business Days thereafter, the Company shall issue and deliver, or cause to be issued and delivered, to the
Holder, registered in such name or names as the Holder may direct in writing, a certificate or certificates for the number of whole
shares of Common Stock issuable upon the conversion of such portion of this Note. The Company shall pay all transfer agent fees
and, to the extent that the Holder may freely resell such shares of Common Stock without volume or manner of sale restrictions
under Rule 144, shall cause its counsel to deliver an appropriate legal opinion in connection with any sales under Rule 144 so
that shares of Common Stock issuable upon the conversion of this Note shall be issued free of restrictive legend. To the extent
permitted by law, such conversion shall be deemed to have been effected, and the Conversion Price shall be determined, as of the
date on which such written notice shall have been received by the Company. The Holder shall return this Note to the Company for
cancellation upon the full conversion or payment thereof. The Person or Persons in whose name or names any certificate or certificates
for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder or holders of record
of the shares represented thereby.

 

(c)               
No fractional shares shall be issued upon any conversion of this Note into Common Stock. If any fractional share of Common
Stock would, except for the provisions of the first sentence of this Section 4(c), be delivered upon such conversion, the Company,
in lieu of delivering such fractional share, shall pay to the Holder an amount in cash equal to the Closing Bid Price of a share
of Common Stock on the effective date of conversion times the fractional share of Common Stock otherwise issuable upon such conversion.
In case the principal amount of this Note exceeds the principal amount being converted, the Company shall, upon such conversion,
execute and deliver to the Holder, at the expense of the Company, a new Note for the principal amount of this Note surrendered
which is not to be converted.

 

    	-4-

    	 

    

 

(d)              
The Company may at any time during the term of this Note reduce the then current Conversion Price to any amount and for
any period of time deemed appropriate by the Board.

 

(e)               
If the Company at any time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization,
reorganization, scheme, arrangement or otherwise) one or more classes of its outstanding shares of Common Stock into a greater
number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the
Company at any time on or after the Issuance Date combines (by any stock split, stock dividend, recapitalization, reorganization,
scheme, arrangement or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares,
the Conversion Price in effect immediately prior to such combination will be proportionately increased. Any adjustment under this
Section 4(e) shall become effective at the close of business on the date the subdivision or combination becomes effective.

 

(f)               
If any event occurs of the type contemplated by the provisions of this Section 4 but not expressly provided for by such
provisions (including, without limitation, the granting of stock appreciation rights or phantom stock rights), then the Board will
make an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder; provided that no such adjustment
pursuant to this Section 4(f) will increase the Conversion Price as otherwise determined pursuant to this Section 4.

 

(g)              
An adjustment to the Conversion Price shall become effective immediately after the payment date in the case of each dividend
or distribution and immediately after the effective date of each other event which requires an adjustment.

 

(h)              
In the event that, as a result of an adjustment made pursuant to this Section 4, the Holder shall become entitled to receive
any shares of capital stock of the Company other than shares of Common Stock, the number of such other shares so receivable upon
conversion of this Note shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly equivalent
as practicable to the provisions contained in this Note.

 

(i)                
In case at any time:

 

(i)the Company shall declare
any dividend upon its Common Stock or any other class or series of capital stock of the Company payable in cash or stock or make
any other distribution to the holders of its Common Stock or any such other class or series of capital stock;

 

(ii)the Company shall offer
for subscription pro rata to the holders of its Common Stock or any other class or series of capital stock of the
Company any additional shares of stock of any class or other rights; or

 

(iii)there shall be any capital
reorganization or reclassification of the capital stock of the Company, any acquisition or a liquidation, dissolution or winding
up of the Company;

 

    	-5-

    	 

    

 

then, in any one or more of said
cases, the Company shall give, by delivery in person or by certified or registered mail, return receipt requested, addressed to
the Holder at the address of such Holder as shown on the books of the Company, (a) at least twenty (20) Business Days’ prior
written notice of the date on which the books of the Company shall close or a record shall be taken for such dividend, distribution
or subscription rights or for determining rights to vote in respect of any event set forth in clause (iii) of this Section 4(j)
and (b) in the case of any event set forth in clause (iii) of this Section 4(j), at least 20 Business Days’ prior written
notice of the date when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also specify,
in the case of any such dividend, distribution or subscription rights, the date on which the holders of Common Stock or such other
class or series of capital stock shall be entitled thereto and such notice in accordance with the foregoing clause (b) shall also
specify the date on which the holders of Common Stock and such other series or class of capital stock shall be entitled to exchange
their Common Stock and other stock for securities or other property deliverable upon consummation of the applicable event set forth
in clause (iii) of this Section 4(i).

 

(j)                
Upon any adjustment of the Conversion Price, then and in each such case the Company shall give prompt written notice thereof,
by delivery in person or by certified or registered mail, return receipt requested, addressed to the Holder at the address of such
Holder as shown on the books of the Company, which notice shall state the Conversion Price resulting from such adjustment and setting
forth in reasonable detail the method upon which such calculation is based.

 

(k)              
The Company shall at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of
issuance upon conversion of this Note as herein provided, such number of shares of Common Stock as shall then be issuable upon
the conversion of this Note. The Company covenants that all shares of Common Stock which shall be so issued shall be duly and validly
issued and fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issue thereof, and, without
limiting the generality of the foregoing, and that the Company will from time to time take all such action as may be requisite
to assure that the par value per share of the Common Stock is at all times equal to or less than the Conversion Price in effect
at the time. The Company shall take all such action as may be necessary to assure that all such shares of Common Stock may be so
issued without violation of any applicable law or regulation, or of any requirement of any national securities exchange or trading
market upon which the Common Stock may be listed. The Company shall not take any action which results in any adjustment of the
Conversion Price if the total number of shares of Common Stock issued and issuable after such action upon conversion of this Note
would exceed the total number of shares of Common Stock then authorized by the Company’s Certificate of Incorporation.

 

(l)                
The issuance of certificates for shares of Common Stock upon conversion of this Note shall be made without charge to the
holders thereof for any issuance tax in respect thereof, provided that the Company shall not be required to pay any tax which may
be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the
Holder.

 

    	-6-

    	 

    

 

(m)            
The Company will not at any time close its transfer books against the transfer, as applicable, of this Note or of any shares
of Common Stock issued or issuable upon the conversion of this Note in any manner which interferes with the timely conversion of
this Note, except as may otherwise be required to comply with applicable securities laws.

 

(n)              
(n)The Company shall not effect the conversion of any portion of this Note, and the Holder shall not have the right
to convert any portion of this Note, to the extent that after giving effect to such conversion, the Holder together with its affiliates
collectively would beneficially own in excess of 4.99% (the "Maximum Percentage") of the shares of Common Stock outstanding
immediately after giving effect to such conversion. For purposes of the foregoing sentence, the aggregate number of shares of Common
Stock beneficially owned by the Holder and the other Affiliates shall include the number of shares of Common Stock held by the
Holder and all other Affiliates plus the number of shares of Common Stock issuable upon conversion of this Note with respect to
which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i)
conversion of the remaining, nonconverted portion of this Note beneficially owned by the Holder or any of the other Affiliates
and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without
limitation, any convertible notes or convertible preferred stock or warrants) beneficially owned by the Holder or any other Attribution
Party subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 4(n). For purposes
of this Section 4(n), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. Upon delivery
of a written notice to the Company, the Holder may from time to time increase (with such increase not effective until the sixty-first
(61st) day after delivery of such notice) or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as
specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first
(61st) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and
the other Affiliates and not to any other holder of Notes that is not an Attribution Party of the Holder. For purposes of clarity,
the shares of Common Stock issuable pursuant to the terms of this Note in excess of the Maximum Percentage shall not be deemed
to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange
Act. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the
terms of this Section 3(d) to the extent necessary to correct this paragraph (or any portion of this paragraph) which may be defective
or inconsistent with the intended beneficial ownership limitation contained in this Section 3(d) or to make changes or supplements
necessary or desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived
and shall apply to a successor holder of this Note.

 

5.             Event
of Default. The occurrence of any of following events shall constitute an “Event of Default” hereunder:

 

(a)               
the failure of the Company to make any payment of principal or interest on this Note when due, whether at the Stated Maturity,
upon acceleration or otherwise;

 

    	-7-

    	 

    

 

(b)              
the Company and/or its Subsidiaries fail to make a required payment or payments on Indebtedness of One Hundred Thousand
United States Dollars ($100,000) or more in aggregate principal amount and such failure continues for more than ten (10) days;

 

(c)               
there shall have occurred an acceleration of the stated maturity of any Indebtedness of the Company or its Subsidiaries
of One Hundred Thousand United States Dollars ($100,000) or more in aggregate principal amount (which acceleration is not rescinded,
annulled or otherwise cured within ten (10) days of receipt by the Company or a Subsidiary of notice of such acceleration);

 

(d)              
the Company or any Subsidiary makes an assignment for the benefit of creditors or admits in writing its inability to pay
its debts generally as they become due; or an order, judgment or decree is entered adjudicating the Company or any Subsidiary as
bankrupt or insolvent; or any order for relief with respect to the Company or any Subsidiary is entered under the Federal Bankruptcy
Code or any other bankruptcy or insolvency law; or the Company or any Subsidiary petitions or applies to any tribunal for the appointment
of a custodian, trustee, receiver or liquidator of the Company or any Subsidiary or of any substantial part of the assets of the
Company or any Subsidiary, or commences any proceeding relating to it under any bankruptcy, reorganization, arrangement, insolvency,
readjustment of debt, dissolution or liquidation law of any jurisdiction; or any such petition or application is filed, or any
such proceeding is commenced, against the Company or any Subsidiary and either (i) the Company or any Subsidiary by any act indicates
its approval thereof, consents thereto or acquiescence therein or (ii) such petition application or proceeding is not dismissed
within sixty (60) days; or

 

(e)               
a final, non-appealable judgment which, in the aggregate with other outstanding final judgments against the Company and
its Subsidiaries, exceeds One Hundred Thousand United States Dollars ($100,000) shall be rendered against the Company or a Subsidiary
and within sixty (60) days after entry thereof, such judgment is not discharged or execution thereof stayed pending appeal, or
within sixty (60) days after the expiration of such stay, such judgment is not discharged; provided, however, that a judgment that
provides for the payment of royalties subsequent to the date of the judgment shall be deemed to be discharged so long as the Company
or the Subsidiary affected thereby is in compliance with the terms of such judgment;

 

Upon the occurrence of any such Event of
Default all unpaid principal and accrued interest under this Note shall become immediately due and payable (A) upon election of
the Holder, with respect to (a) through (c) and (e), and (B) automatically, with respect to (d). Upon the occurrence of any Event
of Default, the Holder may, in addition to declaring all amounts due hereunder to be immediately due and payable, pursue any available
remedy, whether at law or in equity, including, without limitation, exercising its rights under the other Transaction Documents.

 

    	-8-

    	 

    

 

6.             No
Waiver. No delay or omission on the part of the Holder in exercising any right under this Note shall operate as a waiver of
such right or of any other right of the Holder, nor shall any delay, omission or waiver on any one occasion be deemed a bar to
or waiver of the same or any other right on any future occasion.

 

7.             Amendments
in Writing. Any term of this Note may be amended or waived upon the written consent of the Company and the holders of Company
Notes representing at least 50% of the principal amount of Company Notes then outstanding (the “Majority Holders”);
provided, that (x) any such amendment or waiver must apply to all outstanding Company Notes; and (y) without the consent
of the Holder hereof, no amendment or waiver shall (i) change the Stated Maturity Date of this Note, (ii) reduce the principal
amount of this Note or the interest rate due hereon, (iii) increase the Conversion Price or (iv) change the place of payment of
this Note. No such waiver or consent on any one instance shall be construed to be a continuing waiver or a waiver in any other
instance unless it expressly so provides.

 

8.             Waivers.
The Company hereby forever waives presentment, demand, presentment for payment, protest, notice of protest, notice of dishonor
of this Note and all other demands and notices in connection with the delivery, acceptance, performance and enforcement of this
Note.
