Registration Rights.

5.1

Demand Registration.

5.1.1 Grant of Right. The Company, upon written demand (“Demand Notice”) of the Holder(s) of at least 51% of the Purchase Options and/or the underlying Units and/or the underlying securities (“Majority Holders”), agrees to register, on one occasion, all of the then outstanding Units, and/or the Sub-Units, and/or the Class A Warrants, and/or the Ordinary Shares underlying the Sub-Units and Warrants, all underlying such Purchase Options (collectively, the “Registrable Securities”) as requested by the Majority Holders in the Demand Notice, provided that no such registration will be required unless the Holders request registration of an aggregate of at least 51% of the outstanding Registrable Securities. On such occasion, the Company will file a new registration statement or a post-effective amendment to the Registration Statement covering the Registrable Securities within sixty days after receipt of the Demand Notice and use its best efforts to have such registration statement or post-effective amendment declared effective as soon as possible thereafter. The demand for registration may be made at any time during a period of four years beginning on the first anniversary of the Effective Date. The Company covenants and agrees to give written notice of its receipt of any Demand Notice by any Holder(s) to all other registered Holders of the Purchase Options and/or the Registrable Securities within ten days from the date of the receipt of any such Demand Notice, who shall have five days from the receipt of such Notice in which to notify the Company of their desire to have their Registrable Securities included in the Registration Statement.

5.1.2 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the reasonable expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities, but the Holders shall pay any and all underwriting commissions, if any. The Company agrees to use its commercially reasonable efforts if required to qualify or register the Registrable Securities in such States as are reasonably requested by the Majority Holder(s); provided, however, that in no event shall the Company be required to register the Registrable Securities in a State in which such registration would cause: (i) the Company to be obligated to qualify to do business in such State or execute a general consent to service of process, or would subject the Company to taxation as a foreign corporation doing business in such jurisdiction or (ii) the principal shareholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company shall cause any registration statement or post-effective amendment filed pursuant to the demand rights granted under Section 5.1.1 to remain effective for a period of twelve consecutive months from the effective date of such registration statement or post-effective amendment or until the Holders have completed the distribution of the Registrable Securities included in the Registration Statement, whichever occurs first.

5.1.3 Deferred Filing. If: (i) in the good faith judgment of the Board, filing a registration statement pursuant to Section 5.1 would be seriously detrimental to the Company and the Board concludes, as a result, that it is essential to defer the filing of such registration statement at such time, and (ii) the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board it would be materially detrimental to the Company for such registration statement to be filed in the near future and that it is, therefore, essential to defer the filing of such registration statement, then the Company shall have the right to defer such filing on two occasions for an aggregate of not more than one hundred and twenty (120) days in any twelve-month period.

5.2

“Piggy-Back” Registration.

5.2.1 Grant of Right. In addition to the demand right of registration, the Holders of the Purchase Options shall have the right for a period of seven years commencing on the Effective Date, to include the Registrable Securities as part of any other registration of securities filed by the Company (other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Act or pursuant to Form S-8 or any successor or equivalent form); provided, however, that if, in the written opinion of the Company’s managing underwriter or underwriters, if any, for such offering, the inclusion of the Registrable Securities, when added to the securities being registered by the Company or the selling shareholder(s), will exceed the maximum amount of the Company’s securities which can be marketed: (i) at a price reasonably related to their then current market value, and (ii) without materially and adversely affecting the entire offering, then the Company will still be required to include the Registrable Securities, but may require the Holders to agree, in writing, to delay the sale of all or any portion of the Registrable Securities for a period of 90 days from the effective date of the offering, provided, further, that if the sale of any Registrable Securities is so delayed, then the number of securities to be sold by all shareholders in such public offering shall be apportioned pro rata among all such selling shareholders, including all holders of the Registrable Securities, according to the total amount of securities of the Company owned by said selling shareholders, including all holders of the Registrable Securities.

5.2.2 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities, but the Holders shall pay any and all underwriting commissions. In the event of such a proposed registration, the Company shall furnish the then Holders of outstanding Registrable Securities with not less than ten business days written notice prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue to be given for each applicable registration statement filed (during the period in which the Purchase Option is exercisable) by the Company until such time as all of the Registrable Securities have been registered and sold. The holders of the Registrable Securities shall exercise the “piggy back” rights provided for herein by giving written notice, within five business days of the receipt of the Company’s notice of its intention to file a registration statement. The Company shall cause any registration statement filed pursuant to the above “piggyback” rights that does not relate to a firm commitment underwritten offering to remain effective for at least nine consecutive months from the effective date of such registration statement or until the Holders have completed the distribution of the Registrable Securities in the registration statement, whichever occurs first.

5.3

General Terms.

5.3.1 Indemnification. The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against litigation, commenced or threatened, or any claim whatsoever) to which any of them may become subject under the Act, the Exchange Act or otherwise, arising from such registration statement but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the underwriters contained in Section 5 of the Underwriting Agreement in the Offering.

5.3.2 Exercise of Purchase Options. Nothing contained in this Purchase Option shall be construed as requiring the Holder(s) to exercise their Purchase Options or Warrants underlying such Purchase Options prior to or after the initial filing of any registration statement or the effectiveness thereof.

5.3.3 Documents Delivered to Holders. The Company shall furnish Xxxxxx, as representative of the Holders participating in any of the foregoing offerings, a signed counterpart, addressed to the participating Holders, of: (i) an opinion of counsel to the Company, dated the effective date of such registration statement (or, if such registration includes an underwritten public offering, an opinion dated the date of the closing under any underwriting agreement related thereto), and (ii) a “cold comfort” letter dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, a letter dated the date of the closing under the underwriting agreement) signed by the independent public accountants who have issued a report on the Company’s financial statements included in such registration statement, in each case covering substantially the same matters with respect to such registration statement (and the prospectus included therein) and, in the case of such accountants’ letter, with respect to events subsequent to the date of such financial statements, as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters in underwritten public offerings of securities; provided however, that in the case of an underwritten offering, the provisions of the underwriting agreement described in Section 5.4.4 shall control.

Such investigation shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times and as often as Xxxxxx, as representative of the Holders, shall reasonably request. The Company shall not be required to disclose any confidential information or other records to Xxxxxx, as representative of the Holders, or to any other person, until and unless such persons shall have entered into confidentiality agreements (in form and substance reasonably satisfactory to the Company) with the Company with respect thereto.

5.3.4 Underwriting Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s), if any, selected by any Holders whose Registrable Securities are being registered pursuant to this Section 5, which managing underwriter shall be reasonably acceptable to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder and such managing underwriters, and shall contain such representations, warranties and covenants by the Company and such other terms as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be parties to any underwriting agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the representations, warranties and covenants of the Company to or for the benefit of such underwriters shall also be made to and for the benefit of such Holders. Such Holders shall not be required to make any representations or warranties to or agreements with the Company or the underwriters except as they may relate to such Holders and their intended methods of distribution or as are customarily required of selling shareholders in a firm commitment underwritten offering. Such Holders, however, shall agree to such covenants and indemnification and contribution obligations for selling shareholders as are customarily contained in agreements of that type used by the managing underwriter. Further, such Holders shall execute appropriate custody agreements and otherwise cooperate fully in the preparation of the registration statement and other documents relating to any offering in which they include securities pursuant to this Section 5. Each Holder shall also furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be reasonably required to effect the registration of the Registrable Securities.

5.3.5 Rule 144 Sale. Notwithstanding anything contained in this Section 5 to the contrary, the Company shall have no obligation pursuant to Sections 5.1 or 5.2 for the registration of Registrable Securities held by any Holder, where such Holder would then be entitled to sell under Rule 144 within any three-month period (or such other period prescribed under Rule 144 as may be provided by amendment thereof) all of the Registrable Securities then held by such Holder.

5.3.6 Supplemental Prospectus. Each Holder agrees, that upon receipt of any notice from the Company of the happening of any event as a result of which the prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, or that would otherwise require disclosure of material nonpublic information that, if disclosed at such time, would be materially harmful to the Company, such Holder will immediately discontinue disposition of the Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Holder’s receipt of the copies of a supplemental or amended prospectus, or the public disclosure and dissemination of such information, as the case may be, and, if so desired by the Company, such Holder shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of such destruction) all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

5.3.7 Documents to be Delivered by Xxxxxx(s). Each Holder participating in any of the foregoing offerings shall furnish to the Company a completed and executed questionnaire provided by the Company requesting information customarily sought of selling securityholders.

5.3.8 No Net-Cash Settlement or Damages Upon Failure of Registration. In no event shall the registered holder of this Purchase Option and the Warrants underlying the Purchase Option be entitled to: (i) net-cash settlement of this Purchase Option or the Warrants underlying the Purchase Option, regardless of whether any or all of the Registrable Securities have been registered by the Company pursuant to an effective registration statement, or (ii) receive any damages if any or all of the Registrable Securities have not been registered by the Company pursuant to an effective registration statement, subject to the requirement that the Company use its best efforts to have a registration statement or post-effective amendment filed pursuant to this Section 5 declared effective as soon as possible after receiving the Demand Notice. In the event there is no effective registration statement related to the issuance or exercise of the Warrants contained within the Units, that portion of the Units may not be exercised by the holder and therefore may expire and be worthless.

Adjustments.

6.1 Adjustments to Exercise Price and Number of Securities. The Exercise Price and the number of Units underlying the Purchase Option shall be subject to adjustment from time to time as hereinafter set forth:

6.1.1 Share Dividends; Split Ups. If after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding Ordinary Shares is increased by a stock dividend payable in Ordinary Shares or by a split up of Ordinary Shares or other similar event, then, on the effective day thereof, the number of Ordinary Shares underlying each of the Sub-Units underlying the Units purchasable hereunder shall be increased in proportion to such increase in outstanding shares. In such case, the number of Ordinary Shares, and the exercise price applicable thereto, underlying the Warrants underlying each of the Units and Sub-Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrant Agreement Warrant Agreement. For example, if the Company declares a two-for-one share dividend and at the time of such dividend this Purchase Option is for the purchase of one Unit at $10.00 per whole Unit (each of the Warrants underlying the Unit and Sub-Unit underlying the Unit is exercisable for $7.50 per share), upon effectiveness of the dividend, this Purchase Option will be adjusted to allow for the purchase of one Unit at $10.00 per Unit, each Unit entitling the holder to receive two Class A Warrants, and two Sub-Units consisting of two Ordinary Shares and two Class B Warrants (each Warrant exercisable for $3.75 per share).

6.1.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 6.3, the number of outstanding Ordinary Shares is decreased by a consolidation, combination or reclassification of Ordinary Shares or other similar event, then, on the effective date thereof, the number of Ordinary Shares underlying each of the Sub-Units underlying the Units purchasable hereunder shall be decreased in proportion to such decrease in outstanding shares. In such case, the number of Ordinary Shares, and the exercise price applicable thereto, underlying the Warrants purchasable hereunder shall be adjusted in accordance with the terms of the Warrants.

6.1.3 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Ordinary Shares other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such Ordinary Shares, or in the case of any share reconstruction or amalgamation or consolidation of the Company with or into another corporation (other than a consolidation or share reconstruction or amalgamation in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding Ordinary Shares), or in the case of any sale or conveyance to another corporation or entity of the property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Option shall have the right thereafter (until the expiration of the right of exercise of this Purchase Option) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, share reconstruction or amalgamation, or consolidation, or upon a dissolution following any such sale or transfer, by a Holder of the number of Ordinary Shares of the Company obtainable upon exercise of this Purchase Option and the underlying Sub-Units and Warrants immediately prior to such event; and if any reclassification also results in a change in Ordinary Shares covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall similarly apply to successive reclassifications, reorganizations, share reconstructions or amalgamations, or consolidations, sales or other transfers.

6.1.4 Changes in Form of Purchase Option. This form of Purchase Option need not be changed because of any change pursuant to this Section, and Purchase Options issued after such change may state the same Exercise Price and the same number of Units as are stated in the Purchase Options initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new Purchase Options reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement Date or the computation thereof.

6.2 Substitute Purchase Option. In case of any consolidation of the Company with, or share reconstruction or amalgamation of the Company with or into, another corporation (other than a consolidation or share reconstruction or amalgamation which does not result in any reclassification or change of the outstanding Ordinary Shares), the corporation formed by such consolidation or share reconstruction or amalgamation shall execute and deliver to the Holder a supplemental Purchase Option providing that the holder of each Purchase Option then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of such Purchase Option) to receive, upon exercise of such Purchase Option, the kind and amount of shares of stock and other securities and property receivable upon such consolidation or share reconstruction or amalgamation, by a holder of the number of Ordinary Shares of the Company for which such Purchase Option might have been exercised immediately prior to such consolidation, share reconstruction or amalgamation, sale or transfer. Such supplemental Purchase Option shall provide for adjustments which shall be identical to the adjustments provided in Section 6. The above provision of this Section shall similarly apply to successive consolidations or share reconstructions or amalgamations.

6.3 Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Ordinary Shares or Warrants upon the exercise of the Purchase Option, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up or down, as the case may be, to the nearest whole number of Warrants, Ordinary Shares or other securities, properties or rights.

7. Reservation and Listing. The Company shall at all times reserve and keep available out of its authorized Ordinary Shares, solely for the purpose of issuance upon exercise of the Purchase Options or the Warrants underlying the Purchase Option, such number of Ordinary Shares or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Options and payment of the Exercise Price therefor, in accordance with the terms hereby, all Ordinary Shares and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any shareholder. The Company further covenants and agrees that upon exercise of the Warrants underlying the Purchase Options and Units and payment of the respective Warrant exercise price therefor, in accordance with the terms of the Warrant Agreement, all Ordinary Shares and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any shareholder. As long as the Purchase Options shall be outstanding, the Company shall use its commercially reasonable efforts to cause all: (i) Units issuable upon exercise of the Purchase Options, (ii) Sub-Units issuable upon exercise of the Purchase Options and (iii) Warrants issuable upon exercise of the Purchase Options and (iv) Ordinary Shares issuable upon exercise of the Warrants included in the Units and Sub-Units issuable upon exercise of the Purchase Option to be listed (subject to official notice of issuance) on all securities exchanges (or, if applicable on the Nasdaq Global Market, Capital Market, OTC Bulletin Board or any successor trading market) on which the Units, Sub-Units, Public Warrants or Ordinary Shares issued to the public in the Offering may then be listed and/or quoted.

Certain Notice Requirements.

8.1 Holder’s Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or to receive notice as a shareholder for the election of directors or any other matter, or as having any rights whatsoever as a shareholder of the Company.
