The provisions of Section 4(a) and 4(b) hereof shall be binding upon any subsequent transferee of the Series A Preferred Stock or Warrants. B. RESTRICTIVE LEGEND. Each Purchaser acknowledges and agrees that the Series A Preferred Stock or the Warrants, and, until such time as the Common Stock issuable upon conversion of the Series A Preferred Stock or upon exercise of the Warrants shall have been registered under the Securities Act as contemplated by the Registration Rights Agreement and sold in accordance with such Registration Statement, such securities may be subject to a stop-transfer order placed against the transfer of such Securities, and such shares shall bear a restrictive legend in substantially the following form: THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN OPINION OF COUNSEL OR OTHER EVIDENCE SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED. C. FILINGS. The Company undertakes and agrees to make all necessary filings in connection with the sale of the Series A Preferred Stock to each Purchaser as required by United States laws and regulations, or by any domestic securities exchange or trading market, including, if applicable, the filing of a notice on Form D (at such time and in such manner as required by the Rules and Regulations of the Commission), and to provide copies thereof to the Purchaser promptly after such filing or filings. D. STOCK EXCHANGE LISTING. Within ten (10) business days after the Initial Closing Date, the Company shall use its best efforts to file an application for its Common Stock to become listed on the NASDAQ Small Capitalization market or the American Stock Exchange. Notwithstanding the foregoing, if the Company makes a good faith determination that it cannot satisfy the official listing requirements of such exchanges, it shall not be obligated to file such application within such period and will set forth such determination in writing to West End, and will use its best efforts to effect such listing as promptly as possible after it shall satisfy such requirements. The Company agrees that it will not seek to have the trading of its Common Stock through such exchange suspended or terminated, will use its commercially reasonable best efforts to maintain its eligibility for trading through such exchange and, if the trading of its Common Stock is suspended or terminated, will use its commercially reasonable best efforts to requalify its Common Stock or otherwise cause such trading to resume. E. REPORTING STATUS. So long as any of the Purchasers beneficially owns any of the Securities, the Company shall file all reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, and, except in connection with an acquisition transaction in which at least 50% of the Company's voting equity securities or substantially all of the assets of the Company are acquired by another entity, the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would permit such termination. F. STATE SECURITIES FILINGS. The Company shall from time to time promptly take such action as the Purchasers or any of their representatives, if applicable, may reasonably request to qualify the Securities for offering and sale under the securities laws (other than United States federal securities laws) of such jurisdictions in the United States as shall be so identified to the Company, and to comply with such laws so as to permit the continuance of sales therein, provided that in connection therewith, the Company shall not be required to qualify as a foreign corporation or to file a general consent to the service of process in any jurisdiction. G. USE OF PROCEEDS. The Company will use the proceeds from the issuance of the Series A Preferred Stock (excluding amounts paid by the Company for legal fees and finder's fees in connection with the sale of the Series A Preferred Stock) towards the commercialization of products developed with the technologies acquired by the Company in connection with its purchase of all of the issued and outstanding shares of capital stock of (a) Equidyne Systems, Inc. and, (b) the purchase price of all of the issued and outstanding shares of capital stock of Dynamic Dental Systems, Inc. and (c) to repay $600,000 of indebtedness to Citizens Bank New Hampshire, a guaranty savings bank organized under the laws of the State of New Hampshire. To the extent that any of the proceeds from the issuance of the Series A Preferred Stock shall remain, the Company shall use such proceeds for general corporate purposes and working capital. H. RESERVATION OF ORDINARY SHARES. The Company will at all times have authorized and reserved for the purpose of issuance a sufficient number of shares of Common Stock to provide for the conversion of the Series A Preferred Stock and the exercise of the Warrants. The Company will use its best efforts at all times to maintain a number of shares of Common Stock so reserved for issuance that is no less than one and one-half (1.5) times the number that is then actually issuable upon the conversion of the Series A Preferred Stock or the exercise of the Warrants. The number of Common Stock reserved for issuance by the Company upon conversion of the Series A Preferred Stock or upon exercise of the Warrants shall at all times be allocated pro rata among the Purchasers based upon the aggregate purchase price of the Series A Preferred Stock purchased by each Purchaser, and no Purchaser may at any time convert its Series A Preferred Stock or exercise Warrants so as to obtain a greater number of Common Stock than its pro rata allocation of the Company's reserved Common Stock. In the event that a Purchaser shall sell or otherwise transfer, in whole or in part, any of its Securities (except for Common Stock of the Company subject to an effective registration statement under the Securities Act or otherwise freely tradable by such Purchaser), each transferee shall, for purposes of determining such transferee's allocation of the Company's reserved Common Stock, be allocated a pro rata portion of the initial purchase price paid by such Transferor upon its purchase of the Series A Preferred Stock. I. SALES OF ADDITIONAL SHARES. The Company shall not, directly or indirectly, without the prior written consent of West End, offer, sell, offer to sell, contract to sell or otherwise dispose of any shares of its capital stock for a period of two hundred seventy (270) days after the date of this Agreement (the "Lock-Up Period"), except that the Company may (i) issue securities for the aggregate consideration of at least $15.0 million in connection with a bona fide, firm commitment, underwritten public offering under the Securities Act; (ii) may issue shares of Common Stock or securities convertible into, or exercisable for, shares of Common Stock which are issued in connection with a transaction involving the acquisition of another business entity or segment of any such entity by the Company by merger, asset purchase, stock purchase or otherwise; (iii) may issue securities to directors, officers, employees or consultants of the Company for the primary purpose of soliciting or retaining their services; (iv) may issue shares of Common Stock upon the exercise or conversion of currently outstanding options, warrants and other convertible securities; (v) may issue options to purchase shares of its Common Stock to its directors, officers and employees in connection with its existing stock option plans; and (vi) may issue Common Stock in connection with a stock split, stock dividend or similar recapitalization of the Company which affects all holders of the Company's Common Stock on an equivalent basis, in each case, without the prior written consent of West End. Notwithstanding the forgoing, a transaction may only be effected pursuant to clause (ii) above during the Lock-up Period without the prior written consent of West End if the proceeds to the Company from such a transaction are immediately used by the Company to effect an acquisition transaction of the type contemplated by such clause. In addition, the Company agrees that it will not cause any shares of its capital stock that are issued in connection with a transaction of the type contemplated by such clause (or upon the conversion or exercise of other securities that are issued in connection with such transaction) to be covered by a registration statement that is declared effective by the Commission until the earlier to occur of (y) the expiration of the Lock-Up Period or (z) the registration statement filed by the Company pursuant to its obligations under the Registration Rights Agreement has been effective under the Securities Act for a period of at least ninety (90) days. 5. TRANSFER AGENT INSTRUCTIONS. A. The Company warrants that no instruction other than the instructions referred to in this Section 5 and stop transfer instructions to give effect to Sections 4(a) and 4(b) hereof prior to the registration and sale of the Common Stock issuable upon conversion of the Series A Preferred Stock, or in lieu of dividend payments on, the Series A Preferred Stock, or upon exercise of the Warrants under the Securities Act, will be given by the Company to the transfer agent and that such Common Stock shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement, the Registration Rights Agreement, and applicable law. Nothing in this Section shall affect in any way the Purchaser's obligations and agreement to comply with all applicable securities laws upon resale of the Securities. If a Purchaser provides the Company with an opinion of counsel reasonably satisfactory (as to both the identity of such counsel and the content of such opinion) to the Company that registration of a resale by the Purchaser of any of the Securities in accordance with clause (1)(B) of Section 4(a) of this Agreement is not required under the Securities Act, the Company shall (except as provided in clause (2) of Section 4(a) of this Agreement) permit the transfer of the Securities and, in the case of the Common Stock, promptly instruct the Company's transfer agent to issue one or more certificates for Common Stock without legend in such names and in such denominations as specified by the Purchaser. B. The Company will permit each Purchaser to exercise its right to convert the Series A Preferred Stock or to exercise the Warrants by faxing an executed and completed Notice of Conversion or Form of Election to Purchase, as applicable, to the Company, and delivering within three (3) business days thereafter, the original Notice of Conversion (and the related original Series A Preferred Stock) or Form of Election to Purchase (and the related original Warrants) to the Company by hand delivery or by express courier, duly endorsed. Each date on which a Notice of Conversion or Form of Election to Purchase is faxed to and received in accordance with the provisions hereof shall be deemed a "Conversion Date." The Company (or its transfer agent) will transmit the certificates representing the Common Stock issuable upon conversion of the Series A Preferred Stock or upon exercise of any Warrants (together with the Series A Preferred Stock not so converted, or the Warrants not so exercised) to such Purchaser via express courier as soon as practicable, but in all events no later than the later to occur of (the "Delivery Date") (i) four (4) business days after the Conversion Date and (ii) four (4) business days after receipt by the Company of the original Notice of Conversion (and the related original Series A Preferred Stock) or Form of Election to Purchase (and the related original Warrants), as applicable. For purposes of this Agreement, such conversion of the Series A Preferred Stock or exercise of the Warrants shall be deemed to have been made immediately prior to the close of business on the Conversion Date. C. In lieu of delivering physical certificates representing the Common Stock issuable upon the conversion of the Series A Preferred Stock or exercise of the Warrants, provided the Company's transfer agent is participating in the Depositary Trust Company ("DTC") Fast Automated Securities Transfer program, on the written request of a Purchaser who shall have previously instructed such Purchaser's prime broker to confirm such request to the Company's transfer agent, the Company shall use commercially reasonable efforts to cause its transfer agent to electronically transmit such Common Stock to the Purchaser by crediting the account of the Purchaser's prime broker with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system no later than the applicable Delivery Date. D. The Company understands that a delay in the issuance of Common Stock beyond the applicable Delivery Date could result in an economic loss to the applicable Purchaser. As compensation to such Purchaser for such loss, the Company agrees to pay to such Purchaser for late issuance of Common Stock upon conversion of the Series A Preferred Stock or upon exercise of the Warrants the sum of $5,000 per day for each $100,000 in aggregate principal amount of Series A Preferred Stock that are being converted, or for each 25,000 shares of Common Stock purchased upon the exercise of the Warrants. The Company shall pay any payments incurred under this Section 5 in immediately available funds upon demand. Nothing herein shall limit a Purchaser's right to pursue actual damages for the Company's failure to issue and deliver shares of Common Stock to such Purchaser. Furthermore, in addition to any other remedies which may be available to such Purchaser, in the event that the Company fails for any reason to effect delivery of such Common Stock within five (5) business days after the relevant Delivery Date, the Purchaser will be entitled to revoke the relevant Notice of Conversion or Form of Election to Purchase by delivering a notice to such effect to the Company, whereupon the Company and such Purchaser shall each be restored to their respective positions immediately prior to delivery of such Notice of Conversion or Form of Election to Purchase. For purposes of this Section 5, "business day" shall mean any day in which the financial markets of New York are officially open for the conduct of business therein. E. At no time shall any of the Purchasers of the Series A Preferred Stock or the Warrants convert or exercise such amount of the Series A Preferred Stock or the Warrants as shall result in such Purchaser's beneficial ownership, after such conversion, exceeding 9.9% of the Company's outstanding Common Stock, and the parties agree that no Purchaser shall have the right to effect such a conversion or exercise. 6. RIGHT OF FIRST OFFER A. Subject to the terms and conditions specified in this Agreement, the Company hereby grants to West End a right of first offer with respect to future sales by the Company of shares of any class of its capital stock ("Shares"). West End shall be entitled to apportion the right of first offer hereby granted to it among itself and its affiliates in such proportions as it deems appropriate. B. Each time the Company proposes to, prior to the first anniversary of the Initial Closing Date, offer any shares of, or securities convertible into or exercisable for any shares of, any Shares, (except in connection with a bona fide, firm commitment, underwritten public offering), the Company shall first make an offer of such Shares to West End in accordance with the following provisions: (i) The Company shall deliver a notice (the "Notice") to West End stating (A) its bona fide intention to offer such Shares, (B) the number of such Shares to be offered and (C) the price and terms, if any, upon which it proposes to offer such Shares.
