2.1.4 Subscriber is a Person, who is experienced in investing in transactions of the type contemplated by this Subscription Agreement and capable of evaluating investment risks independently, both in general and with regard to transactions and investment strategies involving securities, including Subscriber’s participation in the purchase of the Subscribed for Units Shares.

Part 800.244) and that will acquire a substantial interest in the Company as a result of the purchase and sale of Subscribed for Units hereunder such that a declaration to the Committee on Foreign Investment in the United States would be mandatory under 31 C.F.R.

Neither this Subscription Agreement nor any rights, interests or obligations that may accrue to the parties hereunder (including Subscriber’s rights to purchase the Subscribed for Units) may be transferred or assigned without the prior written consent of the Company; provided that Subscriber’s rights and obligations hereunder may be assigned to any fund or account managed by the same investment manager as Subscriber, without the prior consent of the Company, provided that such assignee(s) agrees in writing to be bound by the terms hereof, and upon such assignment by a Subscriber, the assignee(s) shall become Subscriber hereunder and have the rights and obligations and be deemed to make the representations and warranties of Subscriber provided for herein to the extent of such assignment; provided further that, no assignment shall relieve the assigning party of any of its obligations hereunder, including any assignment to any fund or account managed by the same investment manager as Subscriber.

8.6 Benefit. Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns. This Subscription Agreement shall not confer rights or remedies upon any person other than the parties hereto and their respective successors and assigns.

8.7 Governing Law. This Subscription Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this Subscription Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution, performance or enforcement of this Subscription Agreement, shall be governed by and construed in accordance with the laws of the State of York, without giving effect to the principles of conflicts of law thereof.

8. 8 Consent to Jurisdiction; Waiver of Jury Trial.

8.8.1 The Company and each Subscriber hereby agree that any dispute that may arise between them arising out of or in connection with this Subscription Agreement shall be adjudicated before a court located in the City of New York, Borough of Manhattan, and they hereby submit to the exclusive jurisdiction of the federal and state courts of the State of New York located in the City of New York, Borough of Manhattan with respect to any action or legal proceeding commenced by any party, and irrevocably waive any objection they now or hereafter may have respecting the venue of any such action or proceeding brought in such a court or respecting the fact that such court is an inconvenient forum, relating to or arising out of this Subscription Agreement or any acts or omissions relating to the sale of the securities hereunder, and consent to the service of process in any such action or legal proceeding by means of registered or certified mail, return receipt requested, postage prepaid, in care of the address set forth herein or such other address as either party shall furnish in writing to the other.

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

8.9 Severability. If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

8.10 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Subscription Agreement a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

8.11  Remedies.

8.11.1. The parties agree that irreparable damage would occur if this Subscription Agreement were not performed, or the Closing is not consummated in accordance with its specific terms or is otherwise breached and that monetary damages or other legal remedies would not be an adequate remedy for any such damage. It is accordingly agreed that the parties hereto shall be entitled to equitable relief, including in the form of an injunction or injunctions, to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement in an appropriate court of competent jurisdiction as set forth in Section 7.8, this being in addition to any other remedy to which any party is entitled at law or in equity, including money damages. The right to specific enforcement shall include the right of the parties hereto to cause the other parties hereto to cause the transactions contemplated hereby to be consummated on the terms and subject to the conditions and limitations set forth in this Subscription Agreement. The parties hereto further agree (i) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy, (ii) not to assert that a remedy of specific enforcement pursuant to Section 7.11 is unenforceable, invalid, contrary to applicable law or inequitable for any reason and (iii) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.

8.11.2 The parties acknowledge and agree that Section 7.11 is an integral part of the transactions contemplated hereby and without that right, the parties hereto would not have entered into this Subscription Agreement.

8.12   Mutual Drafting. This Subscription Agreement is the joint product of the parties hereto and each provision hereof has been subject to the mutual consultation, negotiation and agreement of the parties and shall not be construed for or against any party hereto.

8.13 Additional Financings and Offerings. Subscriber recognizes that the Company may seek to raise additional financing and working capital through a variety of sources in the future, or concurrently with the Offering, and that although the Company may undertake one or more public or private offerings of its debt or equity securities, there can be no assurance that any such offering will be made or, if made, that it will be successful. Moreover, Subscriber understands and agrees that the Company reserves the right to make future and concurrent offers, either public or private, of securities, including, but not limited to, promissory notes, shares of common stock, preferred stock or warrants, on terms that may be more than or less favorable than the Securities. Subscriber further confirms that Subscriber has no right to purchase any securities in any future or concurrent offerings. The Company, its affiliates and/or authorized consultants reserve the right at any time to negotiate individually with one or more prospective investors or other persons and to enter into one or more definitive agreements and/or side letters, with one or more of such persons regarding an investment in the Company, on the terms set forth in this subscription or on other terms and conditions, which may be more favorable then the terms set forth herein, or include additional securities of the Company, without prior notice to Subscriber.

8.14 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 any Subscriber or its agents or counsel with any information that the Company believes constitutes or could constitute material non-public information, and each Subscriber agrees, and shall direct its agents and counsel not to, request any material non-public information from the Company or any Person acting on its behalf, unless prior thereto such Subscriber shall have executed a written agreement with the Company regarding the willingness to accept receipt of such material non-public information and acknowledges the confidentiality and use of such information and the Company’s covenant to file a further SEC filing or report and the period in which such information shall remain confidential or be required to not be disclosed. Subscriber is aware of the restrictions imposed by the United States securities laws on the purchase or sale of securities of the Company by any person who has received or has access to material, non-public information (“NPI”) relating to the Company and on the communication of such NPI to any other person when it is reasonably foreseeable that such other person is likely to purchase or sell such securities in reliance upon such information, and in the event that Subscriber has or subsequently receives such NPI or access thereto, Subscriber shall comply with such applicable securities.

8.15 Several, Not Joint Obligations. The obligations of each Subscriber under any Transaction Document are several and not joint with the obligations of any other Subscriber, and no Subscriber shall be responsible in any way for the performance or non-performance of the obligations of any other Subscriber under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any of the Subscribers pursuant hereto or thereto, shall be deemed to constitute Subscribers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Subscribers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Subscriber shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Subscription Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Subscriber to be joined as an additional party in any proceeding for such purpose. The Company has elected to provide all Subscribers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any of the Subscribers. It is expressly understood and agreed that each provision contained in this Subscription Agreement and in each other Transaction Document is between the Company and a Subscriber, solely, and not between the Company and Subscribers collectively and not between and among Subscribers.

8.16 Disclosure. Notwithstanding anything in this Subscription Agreement to the contrary, the Company shall not publicly disclose the name of Subscriber or any of its affiliates, or include the name of Subscriber or any of its affiliates in any press release or in any filing with the Commission or any regulatory agency or trading market, without the prior written consent of Subscriber, except (i) as required by the federal securities law in connection with the Registration Statement, (ii) in a press release to the extent any such disclosure is substantially equivalent to the information that has previously been made public without breach of the obligation under this Section and (iii) to the extent such disclosure is required by law, at the request of the Staff of the Commission or regulatory agency or under the regulations of OTC Markets, LLC., in which case the Company shall provide Subscriber with prior written notice of such disclosure, and shall reasonably consult with the Subscriber regarding such disclosure.

8.17     Counterparts. This Subscription Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or any other form of electronic delivery, 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 signature page were an original thereof.

8.18  Construction. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Subscription Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Subscription Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant. References to Articles, Sections, Exhibits and Schedules are to Articles, Sections, Exhibits and Schedules of this Subscription Agreement unless otherwise specified. All Exhibits and Schedules annexed hereto or referred to herein are hereby incorporated in and made a part of this Subscription Agreement as if set forth in full herein. All references in this Subscription Agreement to numbers of shares, per share amounts and purchase prices shall be appropriately adjusted to reflect any stock split, stock dividend, stock combination, recapitalization or the like occurring after the date hereof. The headings of the sections of this Subscription Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Subscription Agreement. All references to “dollars” or “$” are to United States of America dollars.

Such activity includes placing an advertisement in a publication “with a general circulation in the United States” that refers to the offering of securities being made in reliance upon this Regulation S.

The following are not “directed selling efforts”:

(i) Placing an advertisement required to be published under U.S. or foreign law, or under rules or regulations of a U.S. or foreign regulatory or self-regulatory authority, provided the advertisement contains no more information than legally required and includes a statement to the effect that the securities have not been registered under the Act and may not be offered or sold in the United States (or to a U.S. person, if the advertisement relates to an offering under Category 2 or 3 (paragraph (b)(2) or (b)(3)) in § 230.903) absent registration or an applicable exemption from the registration requirements;

(ii) Contact with persons excluded from the definition of “U.S. person” pursuant to paragraph (k)(2)(vi) of this section or persons holding accounts excluded from the definition of “U.S. person” pursuant to paragraph (k)(2)(i) of this section, solely in their capacities as holders of such accounts;

(iii) A tombstone advertisement in any publication with a general circulation in the United States, provided:

(A) The publication has less than 20% of its circulation, calculated by aggregating the circulation of its U.S. and comparable non-U.S. editions, in the United States;

(1) The issuer's name;

(2) The amount and title of the securities being sold;

(6) The name and address of the person placing the advertisement, and whether such person is participating in the distribution;

(7) The names of the managing underwriters;

(8) The dates, if any, upon which the sales commenced and concluded;

(9) Whether the securities are offered or were offered by rights issued to security holders and, if so, the class of securities that are entitled or were entitled to subscribe, the subscription ratio, the record date, the dates (if any) upon which the rights were issued and expired, and the subscription price; and

(10) Any legend required by law or any foreign or U.S. regulatory or self-regulatory authority;

(iv) Bona fide visits to real estate, plants or other facilities located in the United States and tours thereof conducted for a prospective investor by an issuer, a distributor, any of their respective affiliates or a person acting on behalf of any of the foregoing;

(v) Distribution in the United States of a foreign broker-dealer's quotations by a third-party system that distributes such quotations primarily in foreign countries if:

(A) Securities transactions cannot be executed between foreign broker-dealers and persons in the United States through the system; and

(B) The issuer, distributors, their respective affiliates, persons acting on behalf of any of the foregoing, foreign broker-dealers and other participants in the system do not initiate contacts with U.S. persons or persons within the United States, beyond those contacts exempted under § 240.15a-6 of this chapter;

(vi) Publication by an issuer of a notice in accordance with § 230.135 or § 230.135c;

(vii) Providing any journalist with access to press conferences held outside of the United States, to meetings with the issuer or selling security holder representatives conducted outside the United States, or to written press-related materials released outside the United States, at or in which a present or proposed offering of securities is discussed, if the requirements of § 230.135e are satisfied; and

(viii) Publication or distribution of a research report by a broker or dealer in accordance with Rule 138(c) (§ 230.138(c)) or Rule 139(b) (§ 230.139(b)).

***

“Distribution compliance period” means a period that begins when the securities were first offered to persons other than distributors in reliance upon this Regulation S (§ 230.901 through § 230.905, and Preliminary Notes) or the date of closing of the offering, whichever is later, and continues until the end of the period of time specified in the relevant provision of § 230.903, except that:

(1) All offers and sales by a distributor of an unsold allotment or subscription shall be deemed to be made during the distribution compliance period;
