Subscriber recognizes that the purchase of the Securities involves a high degree of risk including, but not limited to, the following:
(a) the Company has a limited operating history and requires substantial funds in addition to the proceeds of the Offering; (b)
an investment in the Company is highly speculative, and only investors who can afford the loss of their entire investment should

of the Securities is extremely limited; (e) in the event of a disposition, the Subscriber could sustain the loss of its entire
investment; (f) the Company has not paid any dividends since its inception and does not anticipate paying any dividends; and (g)

1.5     At
the time such Subscriber was offered the Securities, it was, and as of the date hereof it is, and on each date on which it converts
the Debentures and/or exercises any Warrants it will be an “accredited investor” as defined in Rule 501(a) under the
Securities Act, as indicated by the Subscriber’s responses to the questions contained in Article VII hereof, and that the
Subscriber is able to bear the economic risk of an investment in the Securities.


 


1.6     The
Subscriber hereby acknowledges and represents that (a) the Subscriber has knowledge and experience in business and financial matters,
prior investment experience, including investment in securities that are non-listed, unregistered and/or not traded on a national
securities exchange or the Subscriber has employed the services of a “purchaser representative” (as defined in Rule

1.8     (a)          In
making the decision to invest in the Securities, the Subscriber has relied solely upon the information provided by the Company

hereunder. The Subscriber disclaims reliance on any statements made or information provided by any person or entity in the course
of Subscriber’s consideration of an investment in the Securities other than the Transaction Documents.

Subscriber represents that (i) the Subscriber was contacted regarding the sale of the Securities by the Placement Agent with whom
the Subscriber had a prior substantial pre-existing relationship and (ii) it did not learn of the offering of the Securities by
means of any form of general solicitation or general advertising, and in connection therewith, the Subscriber did not (A) receive
or review any advertisement, article, notice or other communication published in a newspaper or magazine or similar media or broadcast
over television or radio, whether closed circuit, or generally available; or (B) attend any seminar meeting or industry investor
conference whose attendees were invited by any general solicitation or general advertising.


 


1.9     The
Subscriber hereby acknowledges that the Offering has not been reviewed by the SEC nor any state regulatory authority since the
Offering is intended to be exempt from the registration requirements of Section 5 of the Securities Act, pursuant to Regulation
D. The Subscriber understands that the Securities have not been registered under the Securities Act or under any state securities
or “blue sky” laws and agrees not to sell, pledge, assign or otherwise transfer or dispose of the Securities unless
they are registered under the Securities Act and under any applicable state securities or “blue sky” laws or unless
an exemption from such registration is available.


 


1.10   The
Subscriber understands that the Securities have not been registered under the Securities Act by reason of a claimed exemption under
the provisions of the Securities Act that depends, in part, upon the Subscriber’s investment intention and investment qualification.
In this connection, the Subscriber hereby represents that the Subscriber is purchasing the Securities for the Subscriber’s
own account for investment and not with a view toward the resale or distribution to others; provided, however, that nothing contained
herein shall constitute an agreement by the Subscriber to hold the Securities for any particular length of time and the Company
acknowledges that the Subscriber shall at all times retain the right to dispose of its property as it may determine in its sole
discretion, subject to any restrictions imposed by applicable law. The Subscriber, if an entity, further represents that it was
not formed for the purpose of purchasing the Securities.


 


1.11   The
Subscriber consents to the placement of a legend on any certificate or other document evidencing the Securities and, when issued,
the shares of Common Stock issuable upon conversion of the Debentures (the “Conversion Shares”) and exercise of the
Warrant (the “Warrant Shares” and collectively with the Conversion Shares, the “Shares”) that such securities
have not been registered under the Securities Act or any state securities or “blue sky” laws and setting forth or referring
to the restrictions on transferability and sale thereof contained in this Agreement. The Subscriber is aware that the Company will
make a notation in its appropriate records with respect to the restrictions on the transferability of such Securities or the Shares.


 


1.12   The
Subscriber hereby represents that the address of the Subscriber furnished by Subscriber on the signature page hereof is the Subscriber’s
principal residence if Subscriber is an individual or its principal business address if it is a corporation or other entity.

1.13   Such

Act or any applicable state securities law and is acquiring the Securities as principal for its own account and not with a view
to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state
securities law, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable
state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding
the distribution of such Securities in violation of the Securities Act or any applicable state securities law. Furthermore, such
Subscriber is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding
the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any
seminar or any other general solicitation or general advertisement.


 


1.14   The
Subscriber represents that the Subscriber has full power and authority (corporate, statutory and otherwise) to execute and deliver
this Agreement and to purchase the Securities. This Agreement constitutes the legal, valid and binding obligation of the Subscriber,
enforceable against the Subscriber in accordance with its terms.


 


1.15   If
the Subscriber is a corporation, partnership, limited liability company, trust, employee benefit plan, individual retirement account,
Keogh Plan, or other tax-exempt entity, it is authorized and qualified to invest in the Company and the person signing this Agreement
on behalf of such entity has been duly authorized by such entity to do so.


 


1.16   The
Subscriber acknowledges that if he or she is a Registered Representative of a Financial Industry Regulatory Authority (“FINRA”)
member firm, he or she must give such firm the notice required by the FINRA’s Rules of Fair Practice, receipt of which must
be acknowledged by such firm in Section 7.4 below.


 


1.17   To
effectuate the terms and provisions hereof, the Subscriber hereby appoints the Placement Agent as its attorney-in-fact (and the
Placement Agent hereby accepts such appointment) for the purpose of carrying out the provisions of the Escrow Agreement by and
between the Company, the Placement Agent and Escrow Agent (the “Escrow Agreement”) including, without limitation, taking
any action on behalf of, or at the instruction of, the Subscriber and executing any release notices required under the Escrow Agreement
and taking any action and executing any instrument that the Placement Agent may deem necessary or advisable (and lawful) to accomplish
the purposes hereof. All acts done under the foregoing authorization are hereby ratified and approved and neither the Placement
Agent nor any designee nor agent thereof shall be liable for any acts of commission or omission, for any error of judgment, for
any mistake of fact or law except for acts of gross negligence or willful misconduct. This power of attorney, being coupled with
an interest, is irrevocable while the Escrow Agreement remains in effect.


 


1.18   The
Subscriber agrees not to issue any public statement with respect to the Subscriber’s investment or proposed investment in
the Company or the terms of any agreement or covenant between them and the Company without the Company’s prior written consent,
except such disclosures as may be required under applicable law or under any applicable order, rule or regulation.


 


1.19   The
Subscriber understands, acknowledges and agrees with the Company that this subscription may be rejected, in whole or in part, by
the Company, in the sole and absolute discretion of the Company, at any time before any Closing notwithstanding prior receipt by
the Subscriber of notice of acceptance of the Subscriber’s subscription.


 




    4 


     


    

 


1.20   The
Subscriber acknowledges that the information contained in the Transaction Documents or otherwise made available to the Subscriber
is confidential and non-public and agrees that all such information shall be kept in confidence by the Subscriber and neither used
by the Subscriber for the Subscriber’s personal benefit (other than in connection with this subscription) nor disclosed to
any third party for any reason, notwithstanding that a Subscriber’s subscription may not be accepted by the Company; provided,
however, that (a) the Subscriber may disclose such information to its affiliates and advisors who may have a need for such information
in connection with providing advice to the Subscriber with respect to its investment in the Company so long as such affiliates
and advisors have an obligation of confidentiality, and (b) this obligation shall not apply to any such information that (i) is
part of the public knowledge or literature and readily accessible at the date hereof, (ii) becomes part of the public knowledge
or literature and readily accessible by publication (except as a result of a breach of this provision) or (iii) is received from
third parties without an obligation of confidentiality (except third parties who disclose such information in violation of any
confidentiality agreements or obligations, including, without limitation, any subscription or other similar agreement entered into
with the Company).


 


1.21   The
Subscriber will indemnify and hold harmless the Company and the Placement Agent and, where applicable, their respective directors,
officers, employees, agents, advisors, affiliates and shareholders, and each other person, if any, who controls any of the foregoing
(collectively, the “Issuer Indemnified Parties”) from and against any and all loss, liability, claim, damage and expense
whatsoever (including, but not limited to, any and all fees, costs and expenses whatsoever reasonably incurred in investigating,
preparing or defending against any claim, lawsuit, administrative proceeding or investigation whether commenced or threatened)
(a “Loss”) arising out of or based upon any representation or warranty of the Subscriber contained herein or in any
document furnished by the Subscriber to the Company and/or the Placement Agent in connection herewith being untrue in any material
respect or any breach or failure by the Subscriber to comply with any covenant or agreement made by the Subscriber herein or therein;
and if for any reason (other than a final non-appealable judgment finding any Issuer Indemnified Party liable for losses, claims,
damages, liabilities or expenses for its gross negligence or willful misconduct) the foregoing indemnity is unavailable to an Issuer
Indemnified Party or insufficient to hold an Issuer Indemnified Party harmless, then the Subscriber shall contribute to the amount
paid or payable by an Issuer Indemnified Party as a result of such loss, claim, damage, liability or expense in such proportion
as is appropriate to reflect not only the relative benefits received by the Company or the Placement agent, as applicable, on the
one hand and the Subscriber on the other, but also the relative fault of the Issuer or the Placement Agent, as applicable, on the
one hand and the Subscriber on the other, as well as any relevant equitable considerations; provided, however, that
the Subscriber shall not be liable to indemnify any Issuer Indemnified Parties under this Section or to contribute to the amount
paid or payable by all Issuer Indemnified Parties under this Section in an amount under both such provisions that in the aggregate
exceeds the Subscriber’s aggregate purchase price tendered hereunder.

Company owns or possesses sufficient legal rights to all patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information and other proprietary rights and processes necessary for its business as now conducted and as presently proposed
to be conducted, without any known infringement of the rights of others as set forth on Schedule 2.15 and which the failure

purchase of “off the shelf” or standard products. The Company has not received any written communications alleging
that the Company has violated or, by conducting its business as presently proposed to be conducted, would violate any Intellectual
Property Rights of any other person or entity. The Company and its Subsidiaries have taken reasonable security measures to protect
the secrecy, confidentiality and value of all of their intellectual properties, except where failure to do so could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect


 


(b)          Except
as set forth on Schedule 2.15, the Company is not aware that any of its employees is obligated under any contract (including

business as presently conducted.


 


(c)          Neither
the execution nor delivery of this Agreement, nor the carrying on of the Company’s business by the employees of the Company,
nor the conduct of the Company’s business as presently conducted, will, to the Company’s knowledge, conflict with or
result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant or instrument

the continued employment by the Company of its present employees, and the performance of the Company’s contracts with its
independent contractors, will not result in any such violation. The Company has not received any written notice alleging that any
such violation has occurred. Except as set forth on Schedule 2.15, no employee of the Company has been granted the right

hereunder, none of the Company, its Subsidiaries, any of their affiliates, and any person acting on their behalf has, directly

provisions, including without limitation, under the rules and regulations of any exchange or automated quotation system on which
any of the securities of the Company are listed or designated. Except as set forth in the Transaction Documents or on Schedule

the Subscriber as a result of the Subscriber and the Company fulfilling their obligations or exercising their rights under this
Agreement, including, without limitation, the Company's issuance of the Securities and the Subscriber' ownership of the Securities.

them are obligated to withhold from amounts owing to any employee, creditor or third party. The Company and each subsidiary has

Effect. To the knowledge of the Company, none of the tax returns of the Company nor any of its subsidiaries is currently being
audited by any state, local or federal authorities. Neither the Company nor any subsidiary has waived any statute of limitations

		V.	COVENANTS OF THE COMPANY



 


5.1     Transfer
Restrictions.


 


(a)          The
Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities
other than pursuant to an effective registration statement or Rule 144 promulgated under the Securities Act, to the Company or
to an affiliate of a Subscriber or in connection with, the Company may require the transferor thereof to provide to the Company
an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion
shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred
Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the
terms of this Agreement, and shall have the rights of a Subscriber under this Agreement.


 




    14 


     


    

 


(b)          The
Subscriber agrees to the imprinting, so long as is required by this Section 5.1, of a legend on any of the Securities, including
the Shares, substantially in the following form:


 


[NEITHER] THIS SECURITY [NOR THE SECURITIES
INTO WHICH THIS SECURITY IS [EXERCISABLE] [CONVERTIBLE]] HAS [NOT] BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION
OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL
TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY [AND THE
SECURITIES ISSUABLE UPON [EXERCISE] [CONVERSION] OF THIS SECURITY] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT
OR OTHER LOAN SECURED BY SUCH SECURITIES.


 


(c)          The
Subscriber understands that prior to September 2, 2011, the Company was a “shell company” as defined in Rule 12b-2
under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”). Pursuant to Rule 144(i), securities issued
by a current or former shell company (that is, the Securities and the Shares) that otherwise meet the holding period and other
requirements of Rule 144 nevertheless cannot be sold in reliance on Rule 144 unless at the time of a proposed sale pursuant to
Rule 144 the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act and has filed all reports
and other materials required to be filed by Section 13 or 15(d) of the Exchange Act, as applicable, during the preceding 12 months
(or for such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports. As a
result, the restrictive legends on certificates for the Securities or the Shares cannot be removed except in connection with an
actual sale meeting the foregoing requirements or pursuant to an effective registration statement.


 


(d)          Certificates
evidencing the Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof): (i) while a registration
statement covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Shares
pursuant to Rule 144, or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial
interpretations and pronouncements issued by the staff of the SEC). The Company shall cause its counsel, at the Company’s
expense, to issue a legal opinion to the Company’s transfer agent promptly (but in no event later than the requisite share
delivery date set forth in the Debentures and the Warrants) if required by the Company’s transfer to effect the removal of
the legend hereunder.


 


5.2     Listing
of Securities. The Company agrees, (i) if the Company applies to have the Common Stock traded on any other trading market,
it will include in such application the shares of Common Stock and Shares, and will take such other action as is necessary or desirable
to cause the shares of Common Stock and Shares to be listed on such other trading market as promptly as possible, and (ii) it will
take all action reasonably necessary to continue the listing and trading of its Common Stock on a trading market and will comply
in all material respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the trading
market.


 




    15 


     


    

 


5.3     Reservation
of Shares. Subject to Stockholder Approval (as defined in Section 5.12 of this Agreement), , at all times while the Debentures
and Warrants are outstanding, maintain a reserve from its duly authorized shares of Common Stock of a number of shares of Common
Stock sufficient to allow for the issuance of the Shares.


 


5.4     Replacement
of Securities. If any certificate or instrument evidencing any Securities or the Shares is mutilated, lost, stolen or destroyed,
the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, 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 and customary and reasonable indemnity, if requested. The applicants for a new certificate
or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement
securities. If a replacement certificate or instrument evidencing any securities is requested due to a mutilation thereof, the
Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement.


 


5.5     Furnishing
of Information. Until the time that no Subscriber owns Securities, the Company covenants to maintain the registration of the
Common Stock under Section 12(b) or 12(g) of the Exchange Act and to timely file (or obtain extensions in respect thereof and file
within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange
Act. As long as Subscriber owns Securities, if the Company is not required to file reports pursuant to the Exchange Act, it will
prepare and furnish to Subscriber and make publicly available in accordance with Rule 144(c) such information as is required for
the Subscribers to sell the Securities under Rule 144. The Company further covenants that it will take such further action as any
holder of Securities may reasonably request, to the extent required from time to time to enable such person to sell such Securities
without registration under the Securities Act within the requirements of the exemption provided by Rule 144.


 


5.6     Securities
Laws; Publicity. Unless otherwise required by applicable law, the Company shall, by 8:30 a.m. (New York City time) on the fourth
trading day immediately following the first and last Closings hereunder, issue a Current Report on Form 8-K disclosing the material
terms of the transactions contemplated hereby and including the Transaction Documents as exhibits thereto to the extent required
by law. The Company shall not publicly disclose the name of Subscriber, or include the name of any Subscriber in any filing with
the SEC or any regulatory agency or trading market, without the prior written consent of Subscriber, except: (a) as required by
federal securities law in connection with the filing of final Transaction Documents (including signature pages thereto) with the
SEC and (b) to the extent such disclosure is required by law, in which case the Company shall provide the Subscriber with prior
notice of such disclosure permitted under this clause (b).


 


5.7     Form
D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation
D promulgated under the Securities Act and to provide a copy thereof, promptly upon request of the Subscriber. The Company shall
take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the
Securities for, sale to the Subscriber at the Closing under applicable securities or “Blue Sky” laws of the states
of the United States, and shall provide evidence of such actions promptly upon request of any Subscriber.


 


5.8     Equal
Treatment of Subscribers. 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 any of the Transaction Documents unless the same
consideration is also offered to all of the parties to the Transaction Documents.


 




    16 


     


    

 


5.9          Indemnification. 


 


(a)     The
Company agrees to indemnify and hold harmless the Subscriber, its affiliates and their respective officers, directors, employees,
agents and controlling persons (collectively, the “Subscriber Indemnified Parties”) from and against any and all loss,
liability, damage or deficiency suffered or incurred by any Indemnified Party by reason of any misrepresentation or breach of warranty
by the Company or, after any applicable notice and/or cure periods, nonfulfillment of any covenant or agreement to be performed
or complied with by the Company, in each case contained in this Agreement or any of the other Transaction Documents; and will promptly
reimburse the Subscriber Indemnified Parties for all expenses (including reasonable fees and expenses of legal counsel) as incurred
in connection with the investigation of, preparation for or defense of any pending or threatened claim related to or arising in
any manner out of any of the foregoing, or any action or proceeding arising therefrom (collectively, “Proceedings”),
whether or not such Subscriber Indemnified Party is a formal party to any such Proceeding.


 


(b)    If
for any reason (other than a final non-appealable judgment finding any Subscriber Indemnified Party liable for losses, claims,
damages, liabilities or expenses for its gross negligence or willful misconduct) the foregoing indemnity is unavailable to an Subscriber
Indemnified Party or insufficient to hold an Subscriber Indemnified Party harmless, then the Company shall contribute to the amount
paid or payable by a Subscriber Indemnified Party as a result of such loss, claim, damage, liability or expense in such proportion
as is appropriate to reflect not only the relative benefits received by the Company on the one hand and the Subscriber on the other,
but also the relative fault of the Company or the Placement Agent, as applicable, on the one hand and the Subscriber on the other,
as well as any relevant equitable considerations.


 


(c)     Notwithstanding
the foregoing, the Company shall not be liable to indemnify any Subscriber Indemnified Parties under Section 5.9(a) or to contribute
to the amount paid or payable by all Subscriber Indemnified Parties under Section 5.9(b) in an amount under both such Sections
that in the aggregate exceeds the Subscriber’s aggregate purchase price tendered hereunder.


 


5.10      Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents,
the Company covenants and agrees that neither it, nor any other person acting on its behalf, will provide Subscriber or its agents
or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto Subscriber
shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and
confirms that Subscriber shall be relying on the foregoing covenant in effecting transactions in securities of the Company.


 


5.11      Use
of Proceeds. Except as set forth on Schedule 5.11 attached hereto, the Company shall use the net proceeds from the sale
of the Securities hereunder for working capital purposes and shall not use such proceeds for: (a) the satisfaction of any portion
of the Company’s debt (other than payment of trade payables in the ordinary course of the Company’s business and prior
practices), (b) the redemption of any Common Stock or Common Stock equivalents or (c) the settlement of any outstanding litigation.



 


5.12      Stockholder
Approval.  The Company has filed a proxy statement with the SEC on August 22, 2016 and it shall use its best
efforts to increase its authorized shares of Common Stock from 250,000,000 shares to 500,000,000 shares of Common Stock (the “Charter
Amendment”) or, if, for any reason, such Charter Amendment is not able to be filed, to consummate a 1-for-15 reverse stock
split of its outstanding Common Stock, which reverse stock split was approved on December 1, 2015 by the requisite majority of
Company stockholders and the Company’s board of directors was authorized to effect such reverse stock split at a ratio determined
by them within a range of between 1-for-15 and 1-for-25 (the “Authorized Reverse Stock Split”), on or before October
31, 2016, as may be required to issue all of the shares of Common Stock issuable upon conversion or exercise of, or otherwise with
respect to, the Debentures and the Warrants in accordance with Delaware law and any applicable rules or regulations of the Trading
Market (the “Stockholder Approval”).   The Company shall comply with the filing and disclosure requirements
of Section 14 under the Exchange Act in connection with the Stockholder Approval.  The Company represents and warrants
that its Board of Directors has approved the proposal contemplated by this Section.

6.2     Except
as otherwise provided herein, this Agreement shall not be changed, modified or amended except by a writing signed by the parties
to be charged, and this Agreement may not be discharged except by performance in accordance with its terms or by a writing signed
by the party to be charged. No waiver of any default with respect to any provision, condition or requirement of this 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 provision,
condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair
the exercise of any such right.


 


6.3     This
Agreement shall be binding upon and inure to the benefit of the parties hereto and to their respective heirs, legal representatives,
successors and assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written
consent of Subscriber (other than by merger). Subscriber may assign any or all of its rights under this Agreement to any person
to whom Subscriber assigns or transfers any Securities, provided that such transferee agrees in writing to be bound, with respect
to the transferred Securities, by the provisions of the Transaction Documents


 


6.4     The
Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect
to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters,
which the parties acknowledge have been merged into such documents, exhibits and schedules.


 


6.5    Upon
the execution and delivery of this Agreement by the Subscriber and the Company, this Agreement shall become a binding obligation
of the Subscriber with respect to the purchase of Securities as herein provided, subject, however, to the right hereby reserved
by the Company to enter into the same agreements with other Subscriber and to reject any subscription, in whole or in part, provided
the Company returns to Subscriber any funds paid by Subscriber with respect to such rejected subscription or portion thereof, without
interest or deduction.


 


6.6     All
questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed
by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of
conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense
of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto
or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state
and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the
state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of any dispute hereunder or
in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement
of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding,
any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper
or is an inconvenient venue for such proceeding.


 


6.7     In
order to discourage frivolous claims the parties agree that unless a claimant in any proceeding arising out of this Agreement succeeds
in establishing his claim and recovering a judgment against another party (regardless of whether such claimant succeeds against
one of the other parties to the action), then the other party shall be entitled to recover from such claimant all of its/their
reasonable legal costs and expenses relating to such proceeding and/or incurred in preparation therefor.


 




    19 


     


    

 


6.8    The
holding of any provision of this Agreement to be invalid or unenforceable by a court of competent jurisdiction shall not affect
any other provision of this Agreement, which shall remain in full force and effect. If any provision of this Agreement shall be
declared by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced in whole or in part, such provision
shall be interpreted so as to remain enforceable to the maximum extent permissible consistent with applicable law and the remaining
conditions and provisions or portions thereof shall nevertheless remain in full force and effect and enforceable to the extent
they are valid, legal and enforceable, and no provisions shall be deemed dependent upon any other covenant or provision unless
so expressed herein.


 


6.9     It
is agreed that a waiver by either party of a breach of any provision of this Agreement shall not operate, or be construed, as a
waiver of any subsequent breach by that same party.


 


6.10   The
Company agrees to execute and deliver all such further documents, agreements and instruments and take such other and further action
as may be necessary or appropriate to carry out the purposes and intent of this Agreement.


 


6.11   This
Agreement may be executed in two or more counterparts each of which shall be deemed an original, but all of which shall together
constitute one and the same instrument. 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.


 


6.12   Nothing
in this Agreement shall create or be deemed to create any rights in any person or entity not a party to this Agreement.


 


6.13   In
addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Subscriber
and the Company will be entitled to specific performance under this Agreement. The parties agree that monetary damages may not
be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby
agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.


 


6.14  
Acknowledgment Regarding Subscriber’s Trading Activity. The Company further understands and acknowledges that (a)
Subscriber may engage in hedging activities at various times during the period that the Securities are outstanding, including,
without limitation, during the periods that the value of the Shares deliverable with respect to Securities are being determined,
and (b) such hedging activities (if any) could reduce the value of the existing stockholders' equity interests in the Company at
and after the time that the hedging activities are being conducted.  The Company acknowledges that such aforementioned hedging
activities do not constitute a breach of any of the Transaction Documents.

ANTI-MONEY LAUNDERING REQUIREMENTS


 


	The USA PATRIOT Act	 	What is money laundering?	 	How big is the problem and why

is it important?
	 	 	 	 	 
	The USA PATRIOT Act is designed to detect, deter, and punish terrorists in the United States and abroad.  The Act imposes new anti-money laundering requirements on brokerage firms and financial institutions.  Since April 24, 2002 all brokerage firms have been required to have new, comprehensive anti-money laundering programs. To help you understand these efforts, we want to provide you with some information about money laundering and our steps to implement the USA PATRIOT Act.	 	Money laundering is the process of disguising illegally obtained money so that the funds appear to come from legitimate sources or activities.  Money laundering occurs in connection with a wide variety of crimes, including illegal arms sales, drug trafficking, robbery, fraud, racketeering, and terrorism.	 	The use of the U.S. financial system by criminals to facilitate terrorism or other crimes could well taint our financial markets.  According to the U.S. State Department, one recent estimate puts the amount of worldwide money laundering activity at $1 trillion a year.


 


	What are we required to do to eliminate money laundering?
	 
	Under new rules required by the USA PATRIOT Act, our anti-money laundering program must designate a special compliance officer, set up employee training, conduct independent audits, and establish policies and procedures to detect and report suspicious transaction and ensure compliance with the new laws.	 	As part of our required program, we may ask you to provide various identification documents or other information.  Until you provide the information or documents we need, we may not be able to effect any transactions for you.
