(j) No Undisclosed Events or Circumstances. Since September 30, 2006, no event or circumstance has occurred or exists with respect to the Company or any of its Subsidiaries or their respective businesses, properties, prospects, operations or financial condition, which, under applicable law, rule or regulation, requires public disclosure or announcement by the Company but which has not been so publicly announced or disclosed.

(q) Disclosure. The Company confirms that neither it nor anyone working on its behalf has provided any of the Purchasers or their agents or counsel with any information that constitutes or might constitute material, nonpublic information. To the best of the Company’s knowledge, neither this Agreement or the Schedules hereto nor any other documents, certificates

or instruments furnished to the Purchasers by or on behalf of the Company or its Subsidiaries in connection with the transactions contemplated by this Agreement contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made herein or therein, in the light of the circumstances under which they were made herein or therein, not misleading.

(r) Operation of Business. The Company and its Subsidiaries own or possess all patents, trademarks, domain names (whether or not registered) and any patentable improvements or copyrightable derivative works thereof, websites and intellectual property rights relating thereto, service marks, trade names, copyrights, licenses and authorizations, and all rights with respect to the foregoing, which are necessary for the conduct of its business as now conducted without any conflict with the rights of others.

The Company has all necessary governmental approvals required under all Environmental Laws and used in its business or in the business of its Subsidiaries, except for such instances as would not individually or in the aggregate have a Material Adverse Effect. The Company and its Subsidiaries are also in compliance with all other limitations, restrictions, conditions, standards, requirements, schedules and timetables required or imposed under all Environmental Laws.

Except as set forth on Schedule 2.1(u) hereto, , the Company and its Subsidiaries have in all material respects performed all the obligations required to be performed by them to date under the foregoing agreements, have received no notice of default and, to the best of the Company’s knowledge are not in default under any other Material Agreement now in effect, the result of which could cause a Material Adverse Effect.

(bb) Public Utility Holding Company Act and Investment Company Act Status. The Company is not a “holding company” or a “public utility company” as such terms are defined in the Public Utility Holding Company Act of 1935, as amended. The Company is not, and as a result of and immediately upon the Closing will not be, an “investment company” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.

(cc) ERISA. No liability to the Pension Benefit Guaranty Corporation has been incurred with respect to any Plan by the Company or any of its subsidiaries which is or would be materially adverse to the Company and its subsidiaries. The execution and delivery of this Agreement and the issue and sale of the Preferred Shares will not involve any transaction which is subject to the prohibitions of Section 406 of ERISA or in connection with which a tax could be imposed pursuant to Section 4975 of the Internal Revenue Code of 1986, as amended, provided that, if any of the Purchasers, or any person or entity that owns a beneficial interest in any of the Purchasers, is an “employee pension benefit plan” (within the meaning of Section 3(2) of ERISA) with respect to which the Company is a “party in interest” (within the meaning of Section 3(14) of ERISA), the requirements of Sections 407(d)(5) and 408(e) of ERISA, if applicable, are met.

(dd) Dilutive Effect. The Company understands and acknowledges that the number of Conversion Shares issuable upon conversion of the Preferred Shares and the Warrant Shares issuable upon exercise of the Warrants will increase in certain circumstances. The Company further acknowledges that its obligation to issue Conversion Shares upon conversion of the Preferred Shares in accordance with this Agreement and the Certificate of Designation and its obligations to issue the Warrant Shares upon the exercise of the Warrants in accordance with this Agreement and the Warrants, is, in each case, absolute and unconditional regardless of the dilutive effect that such issuance may have on the ownership interest of other stockholders of the Company.

(ee) No Integrated Offering. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales of any security or solicited any offers to buy any security under circumstances that would cause the offering of the Preferred Shares and Warrants pursuant to this Agreement to be integrated with prior offerings by the Company for purposes of the Securities Act which would prevent the Company from selling the Preferred Shares and Warrants pursuant to Rule 506 under the Securities Act, or any applicable exchange-related stockholder approval provisions, nor will the Company or any of its affiliates or subsidiaries take any action or steps that would cause the offering of the Preferred Shares and Warrants to be integrated with other offerings. The Company does not have any registration statement pending before the Commission or currently under the Commission’s review and since October 1, 2006, the Company has not offered or sold any of its equity securities or debt securities convertible into shares of Common Stock.

(ff) Independent Nature of Purchasers. The Company acknowledges that the obligations of each Purchaser under the Transaction Documents are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under the Transaction Documents. The Company acknowledges that the decision of each Purchaser to purchase securities pursuant to this Agreement has been made by such Purchaser independently of any other purchase and

independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of its Subsidiaries which may have been made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any Purchaser (or any other person) relating to or arising from any such information, materials, statements or opinions. The Company acknowledges that nothing contained herein, or in any Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. The Company acknowledges that each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that for reasons of administrative convenience only, the Transaction Documents have been prepared by counsel for one of the Purchasers and such counsel does not represent all of the Purchasers but only such Purchaser and the other Purchasers have retained their own individual counsel with respect to the transactions contemplated hereby. The Company acknowledges that it has elected to provide all Purchasers 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 the Purchasers. The Company acknowledges that such procedure with respect to the Transaction Documents in no way creates a presumption that the Purchasers are in any way acting in concert or as a group with respect to the Transaction Documents or the transactions contemplated hereby or thereby.

(gg) Sarbanes Oxley; Transfer Agent. The Company has complied with its obligations under the Sarbanes Oxley Act of 2002 and the rules and regulations promulgated thereunder.

The name, address, contact person and telephone number of the Company’s transfer agent is set forth on Schedule 2.1(gg) hereto.

Section 2.2 Representations and Warranties of the Purchasers. Each of the Purchasers severally and not jointly hereby makes the following representations and warranties to the Company with respect solely to itself and not with respect to any other Purchaser:

(a) Organization and Standing of the Purchasers. If the Purchaser is an entity, such Purchaser is a corporation or partnership duly incorporated or organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization.

(b) Authorization and Power. The Purchaser has the requisite power and authority to enter into and perform this Agreement and to purchase the Preferred Shares being sold to it hereunder. The execution, delivery and performance of this Agreement and the Registration Rights Agreement by such Purchaser and the consummation by it of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate or partnership action (if the Purchaser is an entity), and no further consent or authorization of such

Purchaser or its Board of Directors, stockholders, or partners, as the case may be, is required. Each of this Agreement and the Registration Rights Agreement has been duly authorized, executed and delivered by such Purchaser.

(c) No Conflicts. The execution, delivery and performance of this Agreement and the Registration Rights Agreement and the consummation by such Purchaser of the transactions contemplated hereby and thereby or relating hereto do not and will not (i) result in a violation of such Purchaser’s charter documents or bylaws or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of any agreement, indenture or instrument to which such Purchaser is a party, or result in a violation of any law, rule, or regulation, or any order, judgment or decree of any court or governmental agency applicable to such Purchaser or its properties (except for such conflicts, defaults and violations as would not, individually or in the aggregate, have a material adverse effect on such Purchaser). Such Purchaser is not required to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency in order for it to execute, deliver or perform any of its obligations under this Agreement or the Registration Rights Agreement or to purchase the Preferred Shares or acquire the Warrants in accordance with the terms hereof, provided that for purposes of the representation made in this sentence, such Purchaser is assuming and relying upon the accuracy of the relevant representations and agreements of the Company herein.

(d) Acquisition for Investment. Such Purchaser is acquiring the Preferred Shares and the Warrants solely for its own account for the purpose of investment and not with a view to or for sale in connection with distribution. Such Purchaser does not have a present intention to sell the Preferred Shares or the Warrants, nor a present arrangement (whether or not legally binding) or intention to effect any distribution of the Preferred Shares or the Warrants to or through any person or entity, provided that by making the representations herein and subject to Section 2.2(h) below, such Purchaser does not agree to hold the Preferred Shares or the Warrants for any minimum or other specific term and reserves the right to dispose of the Preferred Shares or the Warrants at any time in accordance with Federal and state securities laws applicable to such disposition. Such Purchaser acknowledges that it is able to bear the financial risks associated with an investment in the Preferred Shares and the Warrants and that it has been given full access to such records of the Company and the subsidiaries and to the officers of the Company and the subsidiaries and received such information as it has deemed necessary or appropriate to conduct its due diligence investigation.

(e) Accredited Purchasers. Such Purchaser is an “accredited investor” as defined in Regulation D promulgated under the Securities Act and has such knowledge and experience in financial and business matters that such Purchaser is capable of evaluating the merits and risks of the prospective investment in the Preferred Shares.

(f) Opportunities for Additional Information. Each Purchaser acknowledges that such Purchaser has had the opportunity to ask questions of and receive answers from, or obtain additional information from, the executive officers of the Company concerning the financial and other affairs of the Company, and to the extent deemed necessary in light of such

Purchaser’s personal knowledge of the Company’s affairs, such Purchaser has asked such questions and received answers to the full satisfaction of such Purchaser, and such Purchaser desires to invest in the Company.

(g) No General Solicitation. Each Purchaser acknowledges that the Securities were not offered to such Purchaser by means of any form of general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (i) any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media, or broadcast over television or radio, or (ii) any seminar or meeting to which such Purchaser was invited by any of the foregoing means of communications.

(h) Rule 144. Such Purchaser understands that the Shares must be held indefinitely unless such Shares are registered under the Securities Act or an exemption from registration is available. Such Purchaser acknowledges that such Purchaser is familiar with Rule 144 of the rules and regulations of the Commission, as amended, promulgated pursuant to the Securities Act (“Rule 144”), and that such person has been advised that Rule 144 permits resales only under certain circumstances. Such Purchaser understands that to the extent that Rule 144 is not available, such Purchaser will be unable to sell any Shares without either registration under the Securities Act or the existence of another exemption from such registration requirement.

(i) No Shorting. No Purchaser has engaged in any short sales of the Common Stock or instructed any third parties to engage in any short sales of the Common Stock on its behalf prior to the Closing Date. Each Purchaser covenants and agrees that it will not be in a net short position with respect to the shares of Common Stock. For purposes of this Section 2.2(i), a “net short position” means a sale of Common Stock by a Purchaser that is marked as a short sale and that is made at a time when there is no equivalent offsetting long position in Common Stock held by such Purchaser.

(j) General. Such Purchaser understands that the Shares are being offered and sold in reliance on a transactional exemption from the registration requirement of Federal and state securities laws and the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the Shares.

(k) Certain Exchanges Excepted. For purposes of Section 5(e)(x) of the Series A Certificate of Designation and Series A-1 Certificate of Designation and the definition of “Permitted Issuances” as defined in Section 9 of the Warrants, each Purchaser acknowledges that the exchange of certain warrants outstanding on the date hereof for shares of the Company’s Common Stock shall not require the Company to make an adjustment of the Conversion Price under Section 5(e)(vi) of the Series A Certificate of Designation and Series A-1 Certificate of Designation or an adjustment of the Warrant Price under Section 4(d) of the Warrants

ARTICLE III

Covenants

The Company covenants with each of the Purchasers as follows, which covenants are for the benefit of the Purchasers and their permitted assignees (as defined herein).

Section 3.1 Securities Compliance.

(a) The Company shall notify the Commission in accordance with their rules and regulations, of the transactions contemplated by any of the Transaction Documents, including filing a report on Form 8-K and filing a Form D with respect to the Preferred Shares, Warrants, Conversion Shares and Warrant Shares, if required by the Commission’s rules, and shall take all other necessary action and proceedings as may be required and permitted by applicable law, rule and regulation, for the legal and valid issuance of the Preferred Shares, the Warrants, the Conversion Shares and the Warrant Shares to the Purchasers or subsequent holders.

(b) The Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of such Purchasers set forth herein in order to determine the applicability of Federal and state securities laws exemptions and the suitability of such Purchasers to acquire the Preferred Shares.

Section 3.2 Registration and Listing. The Company will cause its Common Stock to continue to be registered under Sections 12(b) or 12(g) of the Exchange Act, will comply in all respects with its reporting and filing obligations under the Exchange Act, will comply with all requirements related to any registration statement filed pursuant to this Agreement or the Registration Rights Agreement, and will not take any action or file any document (whether or not permitted by the Securities Act or the rules promulgated thereunder) to terminate or suspend such registration or to terminate or suspend its reporting and filing obligations under the Exchange Act or Securities Act, except as permitted herein. The Company will take all action necessary to continue the listing or trading of its Common Stock on the over-the-counter electronic bulletin board and on such other exchange or market on which the Common Stock is trading. If required, the Company will apply any listing application for the Shares and Warrant Shares. The Company further covenants and agrees that it will take such further action as the Purchasers may reasonably request, all to the extent required from time to time to enable the Purchasers to sell the Securities without registration under the Securities Act within the limitation of the exemptions provided in Rule 144 promulgated under the Securities Act. Upon the request of the Purchasers, the Company shall deliver to the Purchasers a written certification of a duly authorized officer as to whether it has complied with such requirement.

Section 3.3 Inspection Rights. The Company shall permit, during normal business hours and upon reasonable request and reasonable notice, each Purchaser or any employees, agents or representatives thereof, so long as such Purchaser shall be obligated hereunder to purchase the Preferred Shares or shall beneficially own any Preferred Shares, or shall own Conversion Shares which, in the aggregate, represent more than 2% of the total combined voting power of all voting securities then outstanding, for purposes reasonably related

to such Purchaser’s interests as a stockholder to examine and make reasonable copies of and extracts from the records and books of account of, and visit and inspect the properties, assets, operations and business of the Company and any subsidiary, and to discuss the affairs, finances and accounts of the Company and any subsidiary with any of its officers, consultants, directors, and key employees.

Section 3.4 Compliance with Laws. The Company shall comply, and cause each subsidiary to comply, with all applicable laws, rules, regulations and orders, noncompliance with which could have a Material Adverse Effect.

Section 3.5 Keeping of Records and Books of Account. The Company shall keep and cause each of its Subsidiaries to keep adequate records and books of account, in which complete entries will be made in accordance with GAAP consistently applied, reflecting all financial transactions of the Company and its Subsidiaries, and in which, for each fiscal year, all proper reserves for depreciation, depletion, obsolescence, amortization, taxes, bad debts and other purposes in connection with its business shall be made.

Section 3.6 Reporting Requirements. If the Company ceases to file its periodic reports with the Commission, or if the Commission ceases making these periodic reports available via the Internet without charge, then at a Purchaser’s request the Company shall furnish the following to such Purchaser so long as such Purchaser shall be obligated hereunder to purchase the Preferred Shares or shall beneficially own any Preferred Shares, or shall own Conversion Shares which, in the aggregate, represent more than 2% of the total combined voting power of all voting securities then outstanding:

(a) Quarterly Reports filed with the Commission on Form 10-Q or Form 10-QSB as soon as available, and in any event within forty-five (45) days after the end of each of the first three fiscal quarters of the Company;

(b) Annual Reports filed with the Commission on Form 10-K or Form 10-KSB as soon as available, and in any event within ninety (90) days after the end of each fiscal year of the Company; and

(c) Copies of all notices and information, including without limitation notices and proxy statements in connection with any meetings, that are provided to holders of shares of Common Stock, contemporaneously with the delivery of such notices or information to such holders of Common Stock.

Section 3.7 Amendments. The Company shall not amend or waive any provision of the Certificate, Bylaws or the Registration Rights Agreement in any way that would adversely affect the liquidation preferences, conversion rights, voting rights or redemption rights of the holders of the Preferred Shares, unless in compliance with the terms of such instruments or agreements.

Section 3.8 Other Agreements. The Company shall not enter into any agreement in which the terms of such agreement would restrict or impair the right or ability to

perform of the Company or any subsidiary under any Transaction Document or the Certificate of Designation.

Section 3.9 Distributions; Subsidiaries. So long as any Preferred Shares or Warrants remain outstanding, the Company agrees that it shall not (i) declare or pay any dividends or make any distributions to any holder(s) of Common Stock or (ii) purchase or otherwise acquire for value, directly or indirectly, any Common Stock or other equity security of the Company. So long as any Preferred Shares or Warrants remain outstanding, the Company agrees that it shall not transfer, assign, pledge, issue or otherwise permit any equity or other ownership interests in the Subsidiaries to be beneficially owned or held by any person other than the Company.

Section 3.10 Status of Dividends. The Company covenants and agrees that (i) no Federal income tax return or claim for refund of Federal income tax or other submission to the Internal Revenue Service will adversely affect the Preferred Shares, any other series of its Preferred Stock, or the Common Stock, and any deduction shall not operate to jeopardize the availability to Purchasers of the dividends received deduction provided by Section 243(a)(1) of the Code or any successor provision, (ii) in no report to shareholders or to any governmental body having jurisdiction over the Company or otherwise will it treat the Preferred Shares other than as equity capital unless required to do so by a governmental body having jurisdiction over the accounts of the Company or by a change in generally accepted accounting principles required as a result of action by an authoritative accounting standards setting body, and (iii) other than pursuant to this Agreement or the Certificate of Designation, it will take no action which would result in the dividends paid by the Company on the Preferred Shares out of the Company’s current or accumulated earnings and profits being ineligible for the dividends received deduction provided by Section 243(a)(1) of the Code. The preceding sentence shall not be deemed to prevent the Company from designating the Preferred Stock as “Convertible Preferred Stock” in its annual and quarterly financial statements in accordance with its prior practice concerning other series of preferred stock of the Company. Notwithstanding the foregoing, the Company shall not be required to restate or modify its tax returns for periods prior to the Closing Date. In the event that the Purchasers have reasonable cause to believe that dividends paid by the Company on the Preferred Shares out of the Company’s current or accumulated earnings and profits will not be treated as eligible for the dividends received deduction provided by Section 243(a)(1) of the Code, or any successor provision, the Company will, at the reasonable request of the Purchasers of 51% of the outstanding Preferred Shares, join with the Purchasers in the submission to the Service of a request for a ruling that dividends paid on the Shares will be so eligible for Federal income tax purposes, at the Purchasers expense. In addition, the Company will reasonably cooperate with the Purchasers (at Purchasers’ expense) in any litigation, appeal or other proceeding challenging or contesting any ruling, technical advice, finding or determination that earnings and profits are not eligible for the dividends received deduction provided by Section 243(a)(1) of the Code, or any successor provision to the extent that the position to be taken in any such litigation, appeal, or other proceeding is not contrary to any provision of the Code or incurred in connection with any such submission, litigation, appeal or other proceeding. Notwithstanding the foregoing, nothing herein contained shall be deemed to preclude the Company from claiming a deduction with respect to such dividends if (i) the Code shall hereafter be amended, or final Treasury regulations thereunder are issued or modified, to

provide that dividends on the Preferred Shares or Conversion Shares should not be treated as dividends for Federal income tax purposes or that a deduction with respect to all or a portion of the dividends on the Shares is allowable for Federal income tax purposes, or (ii) in the absence of such an amendment, issuance or modification and after a submission of a request for ruling or technical advice, the service shall rule or advise that dividends on the shares should not be treated as dividends for Federal income tax purposes. If the Service determines that the Preferred Shares or Conversion Shares constitute debt, the Company may file protective claims for refund.

Section 3.11 Disclosure of Transaction. The Company shall issue a press release describing the material terms of the transactions contemplated hereby (the “Press Release”) on each Closing Date; provided, however, that if such Closing occurs after 4:00 P.M. Eastern Time on any Trading Day, the Company shall issue the Press Release no later than 9:00 A.M. Eastern Time on the first Trading Day following such Closing Date. The Company shall also file with the Commission a Current Report on Form 8-K (the “Form 8-K”) describing the material terms of the transactions contemplated hereby (and attaching as exhibits thereto this Agreement, the Certificate of Designation, the Registration Rights Agreement, the form of Warrant and the Press Release) as soon as practicable following each Closing Date but in no event more than four (4) Trading Days following each Closing Date, which Press Release and Form 8-K shall be subject to prior review and reasonable comment by the Purchasers. “Trading Day” means any day during which the principal exchange on which the Common Stock is traded shall be open for trading.

Section 3.12 Conversions; Opinions. The Company will provide, at the Company’s expense, such legal opinions in the future as are reasonably necessary but only in conformance with federal and state securities regulations for the issuance and resale of the Common Stock issuable upon conversion of the Preferred Shares and exercise of the Warrants pursuant to an effective registration statement, Rule 144 under the 1933 Act or an exemption from registration. In the event that Common Stock is sold in a manner that complies with an exemption from registration, the Company will promptly instruct its counsel (at its expense) to issue to the transfer agent an opinion permitting removal of the legend (indefinitely, if pursuant to Rule 144(k) of the 1933 Act, or to permit sale of the shares if pursuant to the other provisions of Rule 144 of the 1933 Act).

Section 3.13 Reservation of Shares. So long as any of the Preferred Shares or Warrants remain outstanding, the Company shall take all action necessary to at all times have authorized, and reserved for the purpose of issuance, no less than 120% of the aggregate number of shares of Common Stock needed to provide for the issuance of the Conversion Shares and the Warrant Shares.

Section 3.14 Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, to issue certificates, registered in the name of each Purchaser or its respective nominee(s), for the Conversion Shares and the Warrant Shares in such amounts as specified from time to time by each Purchaser to the Company upon conversion of the Preferred Shares or exercise of the Warrants in the form of Exhibit E attached hereto (the “Irrevocable Transfer Agent Instructions”). Prior to registration of the Conversion Shares and the Warrant Shares under the Securities Act, all such certificates shall

bear the restrictive legend specified in Section 6.1 of this Agreement. The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 3.14 will be given by the Company to its transfer agent and that the Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the Registration Rights Agreement. Nothing in this Section 3.14 shall affect in any way each Purchaser’s obligations and agreements set forth in Section 6.1 to comply with all applicable prospectus delivery requirements, if any, upon resale of the Shares. If a Purchaser provides the Company with an opinion of counsel, in a generally acceptable form, to the effect that a public sale, assignment or transfer of the Shares may be made without registration under the Securities Act or the Purchaser provides the Company with reasonable assurances that the Shares can be sold pursuant to Rule 144 without any restriction as to the number of securities acquired as of a particular date that can then be immediately sold, the Company shall permit the transfer, and, in the case of the Conversion Shares and the Warrant Shares, promptly instruct its transfer agent to issue one or more certificates in such name and in such denominations as specified by such Purchaser and, without any restrictive legend. The Company acknowledges that a breach by it of its obligations under this Section 3.14 will cause irreparable harm to the Purchasers by vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 3.14 will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 3.14, that the Purchasers shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

Section 3.15 Disposition of Assets. So long as the Preferred Shares remain outstanding, neither the Company nor any of its Subsidiaries shall sell, transfer or otherwise dispose of any of its properties, assets and rights including, without limitation, its software and intellectual property, to any person except for sales to customers in the ordinary course of business or with the prior written consent of the holders of a majority of the Preferred Shares then outstanding.

Section 3.16 No Issuance of Senior Securities. So long as Preferred Shares and Series A-1 Convertible Preferred Shares with an aggregate of $2,000,000 of stated value (as stated in the Certificate of Designation for the Preferred Shares and Series A-1 Preferred Shares) remains outstanding, the Company shall not, and shall not permit any Subsidiary to, whether by operation of law or otherwise, offer, sell or issue or allow to exist, any securities or financial instruments that would rank senior to or pari passu with the Preferred Shares, Series A-1 Convertible Preferred Stock or Series A-2 Convertible Preferred Stock (or securities or financial instruments convertible or exchangeable into any such securities or financial instruments) with respect to dividends or liquidation, including, without limitation, any Indebtedness, or any ownership or other interest in any Subsidiary, without the prior written approval of at least fifty percent (50%) of the Preferred Shares and Series A-1 Convertible Preferred Stock outstanding (together as one class); provided, however, that no such senior or pari passu securities or financial instruments shall contain (a) a liquidation preference in excess of one (1) times the purchase price paid to the Company therefor, or (b) an annual dividend or interest rate in excess of LIBOR, plus 6 basis points without, in the case of either (a) or (b), the prior written approval of thirty percent (30%) of the Preferred Shares and the Series A-1 Convertible Preferred Stock

outstanding, each voting separately as a class. The provisions of this Section 3.16 shall not apply to (a) the issuance prior to December 31, 2007 of up to $3,000,000 of securities used to settle trade payables ranking pari passu with the Preferred Shares and the Series A-1 Convertible Preferred Shares, provided, that a Release Event has not occurred as of the date of the issuance of such securities and (b) a working capital line of credit, containing typical and customary terms and conditions of up to $2,000,000 issued by a bank, credit, union, governmental agency or similar unaffiliated corporate or institutional lender. For purposes of this Section 3.16, “Indebtedness” means (a) all obligations for borrowed money, (b) all obligations evidenced by bonds, debentures, notes, or other similar instruments and all reimbursement or other obligations in respect of letters of credit, bankers acceptance, current swap agreements, Interest Rate Agreements, interest rate swaps, or other financial products, (c) all capital lease obligations that exceed $100,000 in any fiscal year to the extent incurred in the Company’s ordinary course of business, (d) all obligations or liabilities secured by a lien or encumbrance on any asset of the Company or its Subsidiaries, irrespective of whether such obligation or liability is assumed, (e) all obligations for the deferred purchase price of assets, together with trade debt and other accounts payable that exceed $100,000 in any fiscal year to the extent incurred in the Company’s ordinary course of business, (f) all synthetic leases, and (g) any obligation guaranteeing or intended to guarantee (whether directly or indirectly guaranteed, endorsed, co-made, discounted or sold with recourse) any of the foregoing obligations of any other person; provided, however, Indebtedness shall not include (a) usual and customary trade debt incurred in the ordinary course of business and (b) endorsements for collection or deposit in the ordinary course of business.

Section 3.17 Most Favored Nations Exchange Right; Subsequent Financing. So long as the Preferred Shares and Series A-1 Convertible Preferred Stock remain outstanding, if the Company enters into any equity or equity linked financing (“Subsequent Financing”) on terms more favorable than the terms governing the Preferred Shares and Series A-1 Convertible Preferred Shares, then the Purchasers and PRF in their sole discretion may exchange their Preferred Shares and Series A-1 Convertible Preferred Shares, as the case may be, valued at their stated value, for the securities issued or to be issued in the Subsequent Financing to the extent a Release Event has not occurred with respect to such shares. The term “Release Event” means, with respect to a holder’s shares of Series A Preferred Stock and Series A-1 Preferred Stock, the date on which the Company files a Form 8-K with the Commission disclosing the Company’s receipt of written notice from the U.S. Food and Drug Administration regarding the granting the Issuer the right to commercialize and market (i.e., formal approval of the Issuer’s Pre-Market Application for) its OrCel product for the treatment of venous leg ulcers.

(a) For a period of two (2) years following the Initial Closing Date so long as the Preferred Shares remain outstanding, the Company covenants and agrees to promptly notify (in no event later than five (5) business days after making or receiving an applicable offer) in writing (a “Rights Notice”) the Purchasers who have purchased at least $3,500,000 of Preferred Shares (each, a “Preferred Stockholder” and collectively the “Preferred Stockholders”) of the terms and conditions of any proposed offer or sale to, or exchange with (or other type of distribution to) any third party (a “Subsequent Financing”), of Common Stock or any debt or equity securities convertible, exercisable or exchangeable into Common Stock. The Rights Notice shall describe, in reasonable detail, the proposed Subsequent Financing, the names and investment amounts of all investors participating in the Subsequent Financing (if known), the proposed closing date of the Subsequent Financing, which shall be within twenty (20) calendar

days from the date of the Rights Notice, and all of the terms and conditions thereof and proposed definitive documentation to be entered into in connection therewith. The Rights Notice shall provide each Preferred Stockholder an option (the “Rights Option”) during the ten (10) Trading Days following delivery of the Rights Notice (the “Option Period”) to inform the Company whether such Preferred Stockholder will purchase up to forty percent (40%) of the securities being offered in such Subsequent Financing on the same, absolute terms and conditions as contemplated by such Subsequent Financing. Delivery of any Rights Notice constitutes a representation and warranty by the Company that there are no other material terms and conditions, arrangements, agreements or otherwise except for those disclosed in the Rights Notice, to provide additional compensation to any party participating in any proposed Subsequent Financing, including, but not limited to, additional compensation based on changes in the Purchase Price or any type of reset or adjustment of a purchase or conversion price or to issue additional securities at any time after the closing date of a Subsequent Financing. If the Company does not receive notice of exercise of the Rights Option from the Preferred Stockholder within the Option Period, the Company shall have the right to close the Subsequent Financing on the scheduled closing date with a third party; provided that all of the material terms and conditions of the closing are the same as those provided to the Preferred Stockholder in the Rights Notice. If the closing of the proposed Subsequent Financing does not occur on that date, any closing of the contemplated Subsequent Financing or any other Subsequent Financing shall be subject to all of the provisions of this Section 3.17(a), including, without limitation, the delivery of a new Rights Notice. The provisions of this Section 3.17(a) shall not apply to issuances of securities in a Permitted Financing.

(b) For purposes of this Agreement, a Permitted Financing (as defined hereinafter) shall not be considered a Subsequent Financing. A “Permitted Financing” shall mean (i) securities issued (other than for cash) in connection with a merger, acquisition, or consolidation, (ii) securities issued pursuant to the conversion or exercise of convertible or exercisable securities issued or outstanding on or prior to the date of this Agreement or issued pursuant to this Agreement (so long as the conversion or exercise price in such securities are not amended to lower such price and/or adversely affect the Purchasers), (iii) securities issued in connection with bona fide strategic license agreements or other partnering arrangements so long as such issuances are not for the purpose of raising capital, (iv) Common Stock issued or the issuance or grants of options to purchase Common Stock pursuant to the Company’s stock option plans and employee stock purchase plans or stock incentive plans as they exist on the date of this Agreement or are hereafter adopted or otherwise so long as such issuances in the aggregate do not exceed ten percent (10)% of the issued and outstanding shares of Common Stock as of the Original Issue Date, and (v) any warrants issued to the placement agent and its designees for the transactions contemplated by the Purchase Agreement.

Section 3.22 Affiliate Transaction. Without the prior written consent of holders of at least 50% of the Preferred Shares, the Company and its Subsidiaries shall not engage in any transactions with any officer, director, employee or any Affiliate of the Company or any Subsidiary, including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, in each case in excess of an aggregate of $150,000 each fiscal year, other than (i) for payment of salary, bonus or consulting fees for services rendered, (ii) reimbursement for expenses incurred on behalf of the Company, (iii) for other employee benefits, including stock option agreements under any stock option plan, or stock grants under any plan, of the Company, (iv) stock or option grants authorized by the Board of Directors or by a committee of the Board of Directors the majority of the members of which are independent directors, and (v) all payments to ▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇ pursuant to agreements currently entered or being entered into by them with the Company and referred to in Section 3.19 of this Agreement, the terms of which are outlined in Schedule 3.19 of this Agreement.

Indemnification

Section 8.1 General Indemnity. The Company agrees to indemnify and hold harmless the Purchasers and any finder (and their respective directors, officers, affiliates, agents, successors and assigns) from and against any and all losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys’ fees, charges and disbursements) incurred by the Purchasers as a result of any inaccuracy in or breach of the representations, warranties or covenants made by the Company herein. Each Purchaser severally but not jointly agrees to indemnify and hold harmless the Company and its directors, officers, affiliates, agents, successors and assigns from and against any and all losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys’ fees, charges and disbursements) incurred by the Company as result of any inaccuracy in or breach of the representations, warranties or covenants made by such Purchaser herein. The maximum aggregate liability of each Purchaser pursuant to its indemnification obligations under this Article 8 shall not exceed the portion of the Purchase Price paid by such Purchaser hereunder.

Section 8.2 Indemnification Procedure. Any party entitled to indemnification under this Article VIII (an “indemnified party”) will give written notice to the indemnifying party of any matters giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Article VIII except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnified party a conflict of interest between it and the indemnifying party may exist with respect of such action, proceeding or claim, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. In the event that the indemnifying party advises an indemnified party that it will contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or otherwise compromise or pay such action or claim. In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim, proceeding or action, the indemnified party’s costs and expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder. The indemnified party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim. The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to defend any such action or claim, then the indemnified party shall be entitled to participate in such defense with counsel of its choice at its sole cost and expense. The indemnifying party shall not be liable for

any settlement of any action, claim or proceeding effected without its prior written consent. Notwithstanding anything in this Article VIII to the contrary, the indemnifying party shall not, without the indemnified party’s prior written consent, settle or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim. The indemnification required by this Article VIII shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the indemnified party irrevocably agrees to refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification. The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law.

ARTICLE IX

Each of the Company and the Purchasers consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.

The representations and warranties of the Company and the Purchasers contained in Sections 2.1(o) and (s) should survive indefinitely and those contained in Article II, with the exception of Sections 2.1(o) and (s), shall survive the execution and delivery hereof and the Closing until the date three (3) years from the Closing Date, and the agreements and covenants set forth in Articles I, III, VIII and IX of this Agreement shall survive the execution and delivery hereof and the Closing hereunder until the Purchasers in the aggregate beneficially own (determined in accordance with Rule 13d-3 under the Exchange Act) less than 2% of the total combined voting power of all voting securities then outstanding, provided, that Sections 3.1, 3.2, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.13, 3.14, 3.16, 3.17 and 3.22 shall in no event expire until the Registration Statement required by Section 2 of the Registration Rights Agreement is no longer required to be effective under the terms and conditions of the Registration Rights Agreement.

Expires June 18, 2012


No.: W-A -___ Date of Issuance: June 18, 2007	Number of Shares: ______

FOR VALUE RECEIVED, subject to the provisions hereinafter set forth, the undersigned, Ortec International, Inc., a Delaware corporation (together with its successors and assigns, the “Issuer”), hereby certifies that ______________________ or its registered assigns is entitled to subscribe for and purchase, during the period specified in this Warrant, up to _______________ (________) shares (subject to adjustment as hereinafter provided) of the duly authorized, validly issued, fully paid and non-assessable Common Stock of the Issuer, at an exercise price per share equal to the Warrant Price then in effect, subject, however, to the provisions and upon the terms and conditions hereinafter set forth. Capitalized terms used in this Warrant and not otherwise defined herein shall have the respective meanings specified in Section 9 hereof.

1. Term. The right to subscribe for and purchase shares of Warrant Stock represented hereby shall commence on June 18, 2007 and shall expire at 5:00 p.m., eastern time, on June 18, 2012 (such period being the “Term”).

2. Method of Exercise Payment; Issuance of New Warrant; Transfer and Exchange.

(a) Time of Exercise. The purchase rights represented by this Warrant may be exercised in whole or in part at any time and from time to time during the Term commencing on June 18, 2007.

(b) Method of Exercise. The Holder hereof may exercise this Warrant, in whole or in part, by the surrender of this Warrant (with the exercise form attached hereto duly executed) at the principal office of the Issuer, and by the payment to the Issuer of an amount of consideration therefor equal to the Warrant Price in effect on the date of such exercise multiplied by the number of shares of Warrant Stock with respect to which this Warrant is then being exercised, payable at such Holder’s election (i) by certified or official bank check or by wire transfer to an account designated by the Issuer, (ii) by “cashless exercise” in accordance with the provisions of subsection (c) of this Section 2, but only when a registration statement under the Securities Act providing for resale of all of the Warrant Stock is not then in effect, or (iii) by a combination of the foregoing methods of payment selected by the Holder of this Warrant.

(c) Cashless Exercise. Notwithstanding any provisions herein to the contrary and commencing one (1) year following the Original Issue Date, if (i) the Per Share Market Value of one share of Common Stock is greater than the Warrant Price (at the date of calculation as set forth below) and (ii) a registration statement under the Securities Act providing for the resale of all of the Warrant Stock is not then in effect, in lieu of exercising this Warrant by payment of cash, the Holder may exercise this Warrant by a cashless exercise and shall receive the number of shares of Common Stock equal to an amount (as determined below) by surrender of this Warrant at the principal office of the Issuer together with the properly endorsed Notice of Exercise in which event the Issuer shall issue to the Holder a number of shares of Common Stock computed using the following formula:


	X = Y - (A)(Y)
	B

Where	X =	the number of shares of Common Stock to be issued to the Holder.

	Y =	the number of shares of Common Stock purchasable upon exercise of all of the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being exercised.

	A =	the Warrant Price.

	B =	the Per Share Market Value of one share of Common Stock.

(d) Issuance of Stock Certificates. In the event of any exercise of the rights represented by this Warrant in accordance with and subject to the terms and conditions hereof, (i) certificates for the shares of Warrant Stock so purchased shall be dated the date of such exercise and delivered to the Holder hereof within a reasonable time, not exceeding three (3) Trading Days after such exercise or, at the request of the Holder, issued and delivered to the Depository Trust Company (“DTC”) account on the Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”) within a reasonable time, not exceeding three (3) Trading Days after such exercise, and the Holder hereof shall be deemed for all purposes to be the Holder of the shares of Warrant Stock so purchased as of the date of such exercise and (ii) unless this Warrant has expired, a new Warrant representing the number of shares of Warrant Stock, if any, with respect to which this Warrant shall not then have been exercised (less any amount thereof which shall have been canceled in payment or partial payment of the Warrant

-2-

Price as hereinabove provided) shall also be issued to the Holder hereof at the Issuer’s expense within such time.

(e) Transferability of Warrant. Subject to Section 2(g), this Warrant may be transferred by a Holder without the consent of the Issuer. If transferred pursuant to this paragraph, this Warrant may be transferred on the books of the Issuer by the Holder hereof in person or by the Holder’s duly authorized attorney, upon surrender of this Warrant at the principal office of the Issuer, properly endorsed (by the Holder executing an assignment in the form attached hereto) and upon payment of any necessary transfer tax or other governmental charge imposed upon such transfer. This Warrant is exchangeable at the principal office of the Issuer for Warrants for the purchase of the same aggregate number of shares of Warrant Stock, each new Warrant to represent the right to purchase such number of shares of Warrant Stock as the Holder hereof shall designate at the time of such exchange. All Warrants issued on transfers or exchanges shall be dated the Original Issue Date and shall be identical with this Warrant except as to the number of shares of Warrant Stock issuable pursuant hereto.

(f) Continuing Rights of Holder. The Issuer will, at the time of or at any time after each exercise of this Warrant, upon the request of the Holder hereof, acknowledge in writing the extent, if any, of its continuing obligation to afford to such Holder all rights to which such Holder shall continue to be entitled after such exercise in accordance with the terms of this Warrant, provided that if any such Holder shall fail to make any such request, the failure shall not affect the continuing obligation of the Issuer to afford such rights to such Holder.

(g) Compliance with Securities Laws.


	(i) The Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant and the shares of Warrant Stock to be issued upon exercise hereof are being acquired solely for the Holder’s own account and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any shares of Warrant Stock to be issued upon exercise hereof except pursuant to an effective registration statement, or an exemption from registration, under the Securities Act and any applicable state securities laws.

	(ii) Except as provided in paragraph (iii) below, this Warrant and all certificates representing shares of Warrant Stock issued upon exercise hereof shall be stamped or imprinted with a legend in substantially the following form:

-3-

SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

(iii) The restrictions imposed by this subsection (g) upon the transfer of this Warrant or the shares of Warrant Stock to be purchased upon exercise hereof shall terminate (A) when such securities shall have been resold pursuant to an effective registration statement under the Securities Act, (B) upon the Issuer’s receipt of an opinion of counsel, in form and substance reasonably satisfactory to the Issuer, addressed to the Issuer to the effect that such restrictions are no longer required to ensure compliance with the Securities Act and state securities laws or (C) upon the Issuer’s receipt of other evidence reasonably satisfactory to the Issuer that such registration and qualification under the Securities Act and state securities laws are not required. Whenever such restrictions shall cease and terminate as to any such securities, the Holder thereof shall be entitled to receive from the Issuer (or its transfer agent and registrar), without expense (other than applicable transfer taxes, if any), new Warrants (or, in the case of shares of Warrant Stock, new stock certificates) of like tenor not bearing the applicable legend required by paragraph (ii) above relating to the Securities Act and state securities laws.

(h) Buy In.

In addition to any other rights available to the Holder, if the Issuer fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the Warrant Stock pursuant to an exercise on or before the Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Stock which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Issuer shall (1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of shares of Warrant Stock that the Issuer was required to deliver to the Holder in connection with the exercise at issue times, (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of shares of Warrant Stock for which such exercise was not honored or deliver to the Holder the number of shares of Common Stock that would have been issued had the Issuer timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Issuer shall be required to pay the Holder $1,000. The Holder shall provide the Issuer written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Issuer. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Issuer’s failure to timely deliver certificates representing shares of Common Stock upon exercise of this Warrant as required pursuant to the terms hereof.

3. Stock Fully Paid; Reservation and Listing of Shares; Covenants.

(a) Stock Fully Paid. The Issuer represents, warrants, covenants and agrees that all shares of Warrant Stock which may be issued upon the exercise of this Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges created by or through Issuer. The Issuer further covenants and agrees that during the period within which this Warrant may be exercised, the Issuer will at all times have authorized and reserved for the purpose of the issue upon exercise of this Warrant a number of shares of Common Stock equal to at least 120% of the aggregate number of shares of Common Stock exercisable hereunder to provide for the exercise of this Warrant (without regard to limitations or exercisability set forth in Section 8).

(b) Reservation. If any shares of Common Stock required to be reserved for issuance upon exercise of this Warrant or as otherwise provided hereunder require registration or qualification with any governmental authority under any federal or state law before such shares may be so issued, the Issuer will in good faith use its best efforts as expeditiously as possible at its expense to cause such shares to be duly registered or qualified. If the Issuer shall list any shares of Common Stock on any securities exchange or market it will, at its expense, list thereon, maintain and increase when necessary such listing, of, all shares of Warrant Stock from time to time issued upon exercise of this Warrant or as otherwise provided hereunder, and, to the extent permissible under the applicable securities exchange’s rules, all unissued shares of Warrant Stock which are at any time issuable hereunder, so long as any shares of Common Stock shall be so listed. The Issuer will also so list on each securities exchange or market, and will maintain such listing of, any other securities which the Holder of this Warrant shall be entitled to receive upon the exercise of this Warrant if at the time any securities of the same class shall be listed on such securities exchange or market by the Issuer.

(c) Covenants. The Issuer shall not by any action including, without limitation, amending the Certificate of Incorporation or the by-laws of the Issuer, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder hereof against dilution (to the extent specifically provided herein) or impairment. Without limiting the generality of the foregoing, the Issuer will (i) not permit the par value, if any, of its Common Stock to exceed the then effective Warrant Price, (ii) not amend or modify any provision of the Certificate of Incorporation or by-laws of the Issuer in any manner that would adversely affect the rights of the Holders of the Warrants, (iii) take all such action as may be reasonably necessary in order that the Issuer may validly and legally issue fully paid and nonassessable shares of Common Stock, free and clear of any liens, claims, encumbrances and restrictions (other than as provided herein) upon the exercise of this Warrant, and (iv) use its best efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be reasonably necessary to enable the Issuer to perform its obligations under this Warrant.

(d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence satisfactory to the Issuer of the ownership of and the loss, theft, destruction or mutilation of any Warrant and, in the

-5-

case of any such loss, theft or destruction, upon receipt of indemnity or security satisfactory to the Issuer or, in the case of any such mutilation, upon surrender and cancellation of such Warrant, the Issuer will make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and representing the right to purchase the same number of shares of Common Stock.

4. Adjustment of Warrant Price and Warrant Share Number. The number of shares of Common Stock for which this Warrant is exercisable, and the price at which such shares may be purchased upon exercise of this Warrant, shall be subject to adjustment from time to time as set forth in this Section 4. The Issuer shall give the Holder notice of any event described below which requires an adjustment pursuant to this Section 4 in accordance with Section 5. Notwithstanding any adjustment hereunder, at no time shall the Warrant Price be greater than $1.00 per share except if it is adjusted pursuant to Section 4(b).

(a) Recapitalization, Reorganization, Reclassification, Consolidation, Merger or Sale.


	(i) In case the Issuer after the Original Issue Date shall do any of the following (each, a “Triggering Event”): (a) consolidate with or merge into any other Person and the Issuer shall not be the continuing or surviving corporation of such consolidation or merger, or (b) permit any other Person to consolidate with or merge into the Issuer and the Issuer shall be the continuing or surviving Person but, in connection with such consolidation or merger, any Capital Stock of the Issuer shall be changed into or exchanged for Securities of any other Person or cash or any other property, or (c transfer all or substantially all of its properties or assets to any other Person, or (d) effect a capital reorganization or reclassification of its Capital Stock, then, and in the case of each such Triggering Event, proper provision shall be made so that, upon the basis and the terms and in the manner provided in this Warrant, the Holder of this Warrant shall be entitled upon the exercise hereof at any time after the consummation of such Triggering Event, to the extent this Warrant is not exercised prior to such Triggering Event, to receive at the Warrant Price in effect at the time immediately prior to the consummation of such Triggering Event in lieu of the Common Stock issuable upon such exercise of this Warrant prior to such Triggering Event, the Securities, cash and property to which such Holder would have been entitled upon the consummation of such Triggering Event if such Holder had exercised the rights represented by this Warrant immediately prior thereto (including the right to elect the type of consideration, if applicable), subject to adjustments (subsequent to such corporate action) as nearly equivalent as possible to the adjustments provided for elsewhere in this Section 4. In the event that the surviving entity in any such Triggering Event is not a public company under the Securities Exchange Act of 1934, the common equity securities of which are traded or quoted on a national securities exchange or the OTC Bulletin Board (a “Qualifying Entity”), then the Holder, at its option, shall be permitted to require that the Company pay to the Holder an amount equal to the Black-Scholes value of this Warrant.

	(ii) Notwithstanding anything contained in this Warrant to the contrary and so long as the surviving entity is a Qualifying Entity, the Issuer will not be deemed to have effected any Triggering Event if, prior to the consummation thereof, each Person (other than the Issuer) which may be required to deliver any Securities, cash or property upon

-6-

the exercise of this Warrant as provided herein shall assume, by written instrument delivered to the Holder of this Warrant and reasonably satisfactory to the Holder, (A) the obligations of the Issuer under this Warrant (and if the Issuer shall survive the consummation of such Triggering Event, such assumption shall be in addition to, and shall not release the Issuer from, any continuing obligations of the Issuer under this Warrant) and (B) the obligation to deliver to such Holder such shares of Securities, cash or property as, in accordance with the foregoing provisions of this subsection (a), such Holder shall be entitled to receive, and such Person shall have similarly delivered to such Holder an opinion of counsel for such Person stating that this Warrant shall thereafter continue in full force and effect and the terms hereof (including, without limitation, all of the provisions of this subsection (a)) shall be applicable to the Securities, cash or property which such Person may be required to deliver upon any exercise of this Warrant or the exercise of any rights pursuant hereto.

(b) Stock Dividends, Subdivisions and Combinations. If at any time the Issuer shall:


	(i) set a record date or take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend payable in, or other distribution of, Additional Shares of Common Stock,

	(ii) subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock, or

	(iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock,

then (1) the number of shares of Common Stock for which this Warrant is exercisable immediately after the occurrence of any such event shall be adjusted to equal the number of shares of Common Stock which a record holder of the same number of shares of Common Stock for which this Warrant is exercisable immediately prior to the occurrence of such event would own or be entitled to receive after the happening of such event, and (2) the Warrant Price then in effect shall be adjusted to equal (A) the Warrant Price then in effect multiplied by the number of shares of Common Stock for which this Warrant is exercisable immediately prior to the adjustment divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after such adjustment.

(c) Certain Other Distributions. If at any time the Issuer shall set a record date or take a record of the holders of its Common Stock for the purpose of entitling them to receive any dividend or other distribution of:


	(i) cash (other than a cash dividend payable out of earnings or earned surplus legally available for the payment of dividends under the laws of the jurisdiction of incorporation of the Issuer),

	(ii) any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash, Common Stock Equivalents, Additional Shares of Common Stock or Permitted Issuances), or

-7-


	(iii) any warrants or other rights to subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash, Common Stock Equivalents, Additional Shares of Common Stock or Permitted Issuances),

then (1) the number of shares of Common Stock for which this Warrant is exercisable shall be adjusted to equal the product of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such adjustment multiplied by a fraction (A) the numerator of which shall be the Per Share Market Value of Common Stock at the date of taking such record and (B) the denominator of which shall be such Per Share Market Value minus the amount allocable to one share of Common Stock of any such cash so distributable and of the fair value (as determined in good faith by the Board of Directors of the Issuer) of any and all such evidences of indebtedness, shares of stock, other securities or property or warrants or other subscription or purchase rights so distributable, and (2) the Warrant Price then in effect shall be adjusted to equal (A) the Warrant Price then in effect multiplied by the number of shares of Common Stock for which this Warrant is exercisable immediately prior to the adjustment divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after such adjustment. A reclassification of the Common Stock (other than a change in par value, or from par value to no par value or from no par value to par value) into shares of Common Stock and shares of any other class of stock shall be deemed a distribution by the Issuer to the holders of its Common Stock of such shares of such other class of stock within the meaning of this Section 4(c) and, if the outstanding shares of Common Stock shall be changed into a larger or smaller number of shares of Common Stock as a part of such reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding shares of Common Stock within the meaning of Section 4(b).

(d) Issuance of Additional Shares of Common Stock.

(i) In the event the Issuer shall at any time following the Original Issue Date and prior to a Release Event (as defined below) issue any Additional Shares of Common Stock (otherwise than as provided in the foregoing subsections (a) through (c) of this Section 4), at a price per share less than the Warrant Price then in effect or without consideration, then the Warrant Price upon each such issuance shall be adjusted to the price equal to the consideration per share paid for such Additional Shares of Common Stock. Upon and after a Release Event, the price shall be adjusted to the price (rounded to the nearest cent) determined by multiplying the Warrant Price by a fraction:

(A) the numerator of which shall be equal to the sum of (x) the number of shares of Outstanding Common Stock immediately prior to the issuance of such Additional Shares of Common Stock plus (y) the number of shares of Common Stock (rounded to the nearest whole share) which the aggregate consideration for the total number of such Additional Shares of Common Stock so issued would purchase at a price per share equal to the Warrant Price then in effect, and

-8-


	(B) the denominator of which shall be equal to the number of shares of Outstanding Common Stock immediately after the issuance of such Additional Shares of Common Stock.

(ii) No adjustment of the Warrant Price shall be made under paragraph (i) of Section 4(d) upon the issuance of any Additional Shares of Common Stock which are issued pursuant to the exercise or conversion of any Common Stock Equivalents if any such adjustment shall previously have been made upon the issuance of such Common Stock Equivalents, or upon the issuance of any warrant or other rights therefor pursuant to Sections 4(e) or 4(f), or in connection with any Permitted Issuances. The term “Release Event” means, with respect to the holder’s Warrant Stock, the date on which the Company files a Form 8-K with the Commission disclosing the Company’s receipt of written notice from the U.S. Food and Drug Administration regarding the granting the Issuer the right to commercialize and market (i.e., formal approval of the Issuer’s Pre-Market Application for) its OrCel product for the treatment of venous leg ulcers.

(e) Issuance of Warrants or Other Rights. If at any time prior to a Release Event the Issuer shall take a record of the Holders of its Common Stock for the purpose of entitling them to receive a distribution of, or shall in any manner (whether directly or by assumption in a merger in which the Issuer is the surviving corporation) issue or sell any warrants or options, whether or not immediately exercisable, and the Warrant Consideration (hereafter defined) per share for which Common Stock is issuable upon the exercise of such warrant or option shall be less than the Warrant Price in effect immediately prior to the time of such issue or sale, then the Warrant Price then in effect immediately prior to the time of such issue or sale, shall be adjusted to the price equal to the Warrant Consideration per share for which Common Stock is issuable upon the exercise of such warrant or option. Upon and after a Release Event, this right shall cease. In the event the Issuer shall at any time following a Release Event issue any warrants or options at a price per share less than the Warrant Price then in effect or without consideration, the price shall be adjusted to the price (rounded to the nearest cent) determined by multiplying the Warrant Price by a fraction: (1) the numerator of which shall be equal to the sum of (A) the number of shares of Common Stock outstanding immediately prior to the issuance or sale of such warrants or options plus (B) the number of shares of Common Stock (rounded to the nearest whole share) which the Warrant Consideration multiplied by the number of shares of Common Stock issuable upon the exercise or conversion of all such warrants or options, would purchase at a price per share equal to the Warrant Price then in effect, and (2) the denominator of which shall be equal to the number of shares of Common Stock that would be outstanding assuming the exercise or conversion of all such warrants and options. No adjustments of the Warrant Price then in effect shall be made upon the actual issue of such Common Stock or of such Common Stock Equivalents upon exercise of such warrants or other rights or upon the actual issue of such Common Stock upon such conversion or exchange of such Common Stock Equivalents. No adjustments of the Warrant Price shall be made under this Section 4(e) in connection with any Permitted Issuances.

-9-

Equivalents, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the Common Stock Equivalent Consideration (hereafter defined) per share for which Common Stock is issuable upon such conversion or exchange shall be less than the Warrant Price in effect immediately prior to the time of such issue or sale, or if, after any such issuance of Common Stock Equivalents, the price per share for which Additional Shares of Common Stock may be issuable thereafter is amended or adjusted, and such price as so amended shall be less than the applicable Conversion Price in effect at the time of such amendment or adjustment, then the Warrant Price then in effect immediately prior to the time of such issue or sale, shall upon each such issuance or sale be adjusted to the price equal to the Common Stock Equivalent Consideration per share paid for such Common Share Equivalents. Upon and after a Release Event, this right shall cease. In the event the Issuer shall at any time following a Release Event issue any Common Stock Equivalents for Common Stock Equivalent Consideration per share less than the Warrant Price then in effect or without consideration, then the Warrant Price upon each issuance shall be adjusted to that price (rounded to the nearest cent) determined by multiplying the Warrant Price by a fraction: (1) the numerator of which shall be equal to the sum of (A) the number of shares of Common Stock outstanding immediately prior to the issuance or sale of such Common Stock Equivalents plus (B) the number of shares of Common Stock (rounded to the nearest whole share) which the Common Stock Equivalent Consideration multiplied by the number of shares of Common Stock issuable upon the exercise or conversion of all such Common Stock Equivalents, would purchase at a price per share equal to the Warrant Price then in effect, and (2) the denominator of which shall be equal to the number of shares of Common Stock that would be outstanding assuming the exercise or conversion of all such Common Stock Equivalents. No further adjustment of the Warrant Price then in effect shall be made under this Section 4(f) upon the issuance of any Common Stock Equivalents which are issued pursuant to the exercise of any warrants or other subscription or purchase rights therefor, if any such adjustment shall previously have been made upon the issuance of such warrants or other rights pursuant to Section 4(e). No further adjustments of the Warrant Price then in effect shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Common Stock Equivalents. No adjustments of the Warrant Price shall be made under this Section 4(f) in connection with any Permitted Issuances.

basis of: (i) treating the number of Additional Shares of Common Stock or other property, if any, theretofore actually issued or issuable pursuant to the previous exercise of any such warrants or other rights or any such right of conversion or exchange, as having been issued on the date or dates of any such exercise and for the consideration actually received and receivable therefor, and (ii) treating any such Common Stock Equivalents which then remain outstanding as having been granted or issued immediately after the time of such increase of the consideration per share for which shares of Common Stock or other property are issuable under such Common Stock Equivalents; whereupon a new adjustment of the Warrant Price then in effect shall be made, which new adjustment shall supersede the previous adjustment so rescinded and annulled.

(h) Purchase of Common Stock by the Issuer. If the Issuer at any time while this Warrant is outstanding shall, directly or indirectly through a Subsidiary or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock at a price per share greater than the Per Share Market Value, then the Warrant Price upon each such purchase, redemption or acquisition shall be adjusted to that price determined by multiplying such Warrant Price by a fraction (i) the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such purchase, redemption or acquisition minus the number of shares of Common Stock which the aggregate consideration for the total number of such shares of Common Stock so purchased, redeemed or acquired would purchase at the Per Share Market Value; and (ii) the denominator of which shall be the number of shares of Common Stock outstanding immediately after such purchase, redemption or acquisition. For the purposes of this subsection (h), the date as of which the Per Share Market Price shall be computed shall be the earlier of (x) the date on which the Issuer shall enter into a firm contract for the purchase, redemption or acquisition of such Common Stock, or (y) the date of actual purchase, redemption or acquisition of such Common Stock. For the purposes of this subsection (h), a purchase, redemption or acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the underlying Common Stock, and the computation herein required shall be made on the basis of the full exercise, conversion or exchange of such Common Stock Equivalent on the date as of which such computation is required hereby to be made, whether or not such Common Stock Equivalent is actually exercisable, convertible or exchangeable on such date.

(i) Other Provisions applicable to Adjustments under this Section. The following provisions shall be applicable to the making of adjustments of the Warrant Price then in effect provided for in this Section 4:

-11-


	then, except as herein otherwise expressly provided, the amount of such consideration shall be deemed to be the fair value of such consideration at the time of such issuance as mutually determined in good faith by the Board of Directors of the Issuer and the Majority Holders. The consideration for any Additional Shares of Common Stock issuable pursuant to any warrants or other rights to subscribe for or purchase the same shall be the consideration received by the Issuer for issuing such warrants or other rights divided by the number of shares of Common Stock issuable upon the exercise of such warrant or right plus the additional consideration payable to the Issuer upon exercise of such warrant or other right for one share of Common Stock (together the “Warrant Consideration”). The consideration for any Additional Shares of Common Stock issuable pursuant to the terms of any Common Stock Equivalents shall be the consideration received by the Issuer for issuing such Common Stock Equivalent, divided by the number of shares of Common Stock issuable upon the conversion or other exercise of such Common Stock Equivalent, plus the additional consideration, if any, payable to the Issuer upon the exercise of the right of conversion or exchange in such Common Stock Equivalent for one share of Common Stock (together the “Common Stock Equivalent Consideration”). In case of the issuance at any time of any Additional Shares of Common Stock or Common Stock Equivalents in payment or satisfaction of any dividends upon any class of stock other than Common Stock, the Issuer shall be deemed to have received for such Additional Shares of Common Stock or Common Stock Equivalents a consideration equal to the amount of such dividend so paid or satisfied.

	(ii) No Adjustments of Number of Shares. No adjustment of the number of shares of Common Stock for which this Warrant shall be exercisable shall be made because of any adjustments of the Warrant Price pursuant to Sections (d), (e), (f), (g) and (h) of this Section 4.

	(iii) Fractional Interests. In computing adjustments under this Section 4, fractional interests in Common Stock shall be taken into account to the nearest one one-hundredth (1/100^th) of a share.

	(iv) When Adjustment Not Required. If the Issuer shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or distribution or subscription or purchase rights and shall, thereafter and before the distribution to stockholders thereof, legally abandon its plan to pay or deliver such dividend, distribution, subscription or purchase rights, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

(j) Form of Warrant after Adjustments. The form of this Warrant need not be changed because of any adjustments in the Warrant Price or the number and kind of securities purchasable upon exercise of this Warrant.

-12-

upon and to the extent that the event actually takes place, upon payment of the then current Warrant Price. Notwithstanding any other provision to the contrary herein, if the event for which such record was taken fails to occur or is rescinded, then such escrowed property shall be returned to the Issuer.

5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share Number shall be adjusted pursuant to Section 4 hereof (for purposes of this Section 5, each an “adjustment”), the Issuer shall cause its Chief Financial Officer to prepare and execute a certificate setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a description of the basis on which the Board made any determination hereunder), and the Warrant Price and Warrant Share Number after giving effect to such adjustment, and shall cause copies of such certificate to be delivered to the Holder of this Warrant promptly after each adjustment. Any dispute between the Issuer and the Holder of this Warrant with respect to the matters set forth in such certificate may at the option of the Holder of this Warrant be submitted to one of the national accounting firms currently known as the “big five” selected by the Holder, provided that the Issuer shall have ten (10) days after receipt of notice from such Holder of its selection of such firm to object thereto, in which case such Holder shall select another such firm and the Issuer shall have no such right of objection. The firm selected by the Holder of this Warrant as provided in the preceding sentence shall be instructed to deliver a written opinion as to such matters to the Issuer and such Holder within thirty (30) days after submission to it of such dispute. Such opinion shall be final and binding on the parties hereto.

7. Intentionally Omitted.

8. Certain Exercise Restrictions. Notwithstanding anything to the contrary set forth in this Warrant, at no time may a holder of this Warrant exercise this Warrant if the number of shares of Common Stock to be issued pursuant to such exercise would exceed, when aggregated with all other shares of Common Stock owned by such holder at such time, the number of shares of Common Stock which would result in such holder beneficially owning (as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules thereunder) in excess of 9.999% of all of the Common Stock outstanding at such time; provided, however, that upon a holder of this Warrant providing the Issuer with sixty-one (61) days notice (pursuant to Section 13 hereof) (the “Waiver Notice”) that such holder would like to waive this Section 8 with regard to any or all shares of Common Stock issuable upon exercise of this Warrant, this Section 8 will be of no force or effect with regard to all or a portion of the Warrant referenced in the Waiver Notice; provided, further, that this provision shall be of no further force or effect during the sixty-one (61) days immediately preceding the expiration of the term of this Warrant.

(b) Method of Exercise. The Holder hereof may exercise this Warrant, in whole or in part, by the surrender of this Warrant (with the exercise form attached hereto duly executed) at the principal office of the Issuer, and by the payment to the Issuer of an amount of consideration therefor equal to the Warrant Price in effect on the date of such exercise multiplied by the number of shares of Warrant Stock with respect to which this Warrant is then being exercised, payable at such Holder’s election by certified or official bank check or by wire transfer to an account designated by the Issuer.

For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Issuer shall be required to pay the Holder $1,000. The Holder shall provide the Issuer written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Issuer. Nothing herein shall limit a Holder’s right to pursuant any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Issuer’s failure to timely deliver certificates representing shares of Common Stock upon exercise of this Warrant as required pursuant to the terms hereof.

time issued upon exercise of this Warrant or as otherwise provided hereunder, and, to the extent permissible under the applicable securities exchange’s rules, all unissued shares of Warrant Stock which are at any time issuable hereunder, so long as any shares of Common Stock shall be so listed. The Issuer will also so list on each securities exchange or market, and will maintain such listing of, any other securities which the Holder of this Warrant shall be entitled to receive upon the exercise of this Warrant if at the time any securities of the same class shall be listed on such securities exchange or market by the Issuer.

(d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence satisfactory to the Issuer of the ownership of and the loss, theft, destruction or mutilation of any Warrant and, in the case of any such loss, theft or destruction, upon receipt of indemnity or security satisfactory to the Issuer or, in the case of any such mutilation, upon surrender and cancellation of such Warrant, the Issuer will make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and representing the right to purchase the same number of shares of Common Stock.

In the event that the surviving entity in any such Triggering Event is not a public company under the Securities Exchange Act of 1934, the common equity securities of which are traded or quoted on a national securities exchange or the OTC Bulletin Board (a “Qualifying Entity”), then the Holder, at its option, shall be permitted to require that the Company pay to the Holder an amount equal to the Black-Scholes value of this Warrant.

	(ii) Notwithstanding anything contained in this Warrant to the contrary and so long as the surviving entity is a Qualifying Entity, the Issuer will not be deemed to have effected any Triggering Event if, prior to the consummation thereof, each Person (other than the Issuer) which may be required to deliver any Securities, cash or property upon the exercise of this Warrant as provided herein shall assume, by written instrument delivered to the Holder of this Warrant and reasonably satisfactory to the Holder, (A) the obligations of the Issuer under this Warrant (and if the Issuer shall survive the consummation of such Triggering Event, such assumption shall be in addition to, and shall not release the Issuer from, any continuing obligations of the Issuer under this Warrant) and (B) the obligation to deliver to such Holder such shares of Securities, cash or property as, in accordance with the foregoing provisions of this subsection (a), such Holder shall be entitled to receive, and such Person shall have similarly delivered to such Holder an opinion of counsel for such Person stating that this Warrant shall thereafter continue in full force and effect and the terms hereof (including, without limitation, all of the provisions of this subsection (a)) shall be applicable to the Securities, cash or property which such Person may be required to deliver upon any exercise of this Warrant or the exercise of any rights pursuant hereto.

(b) Stock Dividends, Subdivisions and Combinations. If at any time the Issuer shall:


	(i) set a record date or take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend payable in, or other distribution of, Common Stock,

		(ii) subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock, or

		(iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock,

	(ii) any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash), or

	(iii) any warrants or other rights to subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash),

-7-

the meaning of this Section 4(c) and, if the outstanding shares of Common Stock shall be changed into a larger or smaller number of shares of Common Stock as a part of such reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding shares of Common Stock within the meaning of Section 4(b).


	(d)	Intentionally Omitted.

	(e)	Intentionally Omitted.

	(f)	Intentionally Omitted.

	(g)	Intentionally Omitted.

	(h)	Intentionally Omitted.

(i) Other Provisions applicable to Adjustments under this Section. The following provisions shall be applicable to the making of adjustments of the Warrant Price then in effect provided for in this Section 4:


	(i) Intentionally Omitted.

	(ii) No Adjustments of Number of Shares. No adjustment of the number of shares of Common Stock for which this Warrant shall be exercisable shall be made because of any adjustments of the Warrant Price pursuant to Sections (d), (e), (f), (g) and (h) of this Section 4.

	(iii) Fractional Interests. In computing adjustments under this Section 4, fractional interests in Common Stock shall be taken into account to the nearest one one-hundredth (1/100^th) of a share.

	(iv) When Adjustment Not Required. If the Issuer shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or distribution or subscription or purchase rights and shall, thereafter and before the distribution to stockholders thereof, legally abandon its plan to pay or deliver such dividend, distribution, subscription or purchase rights, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

(j) Form of Warrant after Adjustments.The form of this Warrant need not be changed because of any adjustments in the Warrant Price or the number and kind of securities purchasable upon exercise of this Warrant.

(k) Escrow of Property. If after any property becomes distributable pursuant to this Section 4 by reason of the taking of any record of the holders of Common Stock, but prior to the occurrence of the event for which such record is taken, and the Holder exercises this Warrant, such property shall be held in escrow for the Holder by the Issuer to be distributed to the Holder upon and to the extent that the event actually takes place, upon payment of the then current Warrant Price. Notwithstanding any other provision to the contrary herein, if the event for which

-8-

such record was taken fails to occur or is rescinded, then such escrowed property shall be returned to the Issuer.

6. Fractional Shares. No fractional shares of Warrant Stock will be issued in connection with and exercise hereof, but in lieu of such fractional shares, the Issuer shall at its option either (a) make a cash payment therefor equal in amount to the product of the applicable fraction multiplied by the Per Share Market Value then in effect or (b) issue one whole share in lieu of such fractional share. Fractional shares of Series D-2 Preferred Stock may be issued by the Company in connection with the exercise of this Warrant for Series D-2 Preferred Stock in lieu of Warrant Stock.

7. Intentionally Omitted.

8. Certain Exercise Restrictions. Notwithstanding anything to the contrary set forth in this Warrant, at no time may a holder of this Warrant exercise this Warrant if the number of shares of Common Stock to be issued pursuant to such exercise would exceed, when aggregated with all other shares of Common Stock owned by such holder at such time, the number of shares of Common Stock which would result in such holder beneficially owning (as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules thereunder) in excess of 9.999% of all of the Common Stock outstanding at such time; provided, however, that upon a holder of this Warrant providing the Issuer with sixty-one (61) days notice (pursuant to Section 13 hereof) (the “Waiver Notice”) that such holder would like to waive this Section 7(b) with regard to any or all shares of Common Stock issuable upon exercise of this Warrant, this Section 7(b) will be of no force or effect with regard to all or a portion of the Warrant referenced in the Waiver Notice.

If the Holder elects to exercise this Warrant and such exercise would result in such Holder beneficially owning (in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules thereunder) more than 9.999% of all of the Common Stock

-9-

issued and outstanding at such time, such Holder may elect to exercise this Warrant for the Company’s Series D-2 Convertible Preferred Stock.

(g) Compliance with Securities Laws.


	(i) The Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant and the shares of Warrant Stock to be issued upon exercise hereof are being acquired solely for the Holder’s own account and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any shares of Warrant Stock to be issued upon exercise hereof except pursuant to an effective registration statement, or an exemption from registration, under the Securities Act and any applicable state securities laws.

	(ii) Except as provided in paragraph (iii) below, this Warrant and all certificates representing shares of Warrant Stock issued upon exercise hereof shall be stamped or imprinted with a legend in substantially the following form:

-3-


		THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR ORTEC INTERNATIONAL, INC.

Whenever such restrictions shall cease and terminate as to any such securities, the Holder thereof shall be entitled to receive from the Issuer (or its transfer agent and registrar), without expense (other than applicable transfer taxes, if any), new Warrants (or, in the case of shares of Warrant Stock, new stock certificates) of like tenor not bearing the applicable legend required by paragraph (ii) above relating to the Securities Act and state securities laws.

(h) Buy In.

-4-

shares of Common Stock that would have been issued had the Issuer timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Issuer shall be required to pay the Holder $1,000. The Holder shall provide the Issuer written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Issuer. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Issuer’s failure to timely deliver certificates representing shares of Common Stock upon exercise of this Warrant as required pursuant to the terms hereof.

3. Stock Fully Paid; Reservation and Listing of Shares; Covenants.

-5-

taking of all such actions as may be necessary or appropriate to protect the rights of the Holder hereof against dilution (to the extent specifically provided herein) or impairment. Without limiting the generality of the foregoing, the Issuer will (i) not permit the par value, if any, of its Common Stock to exceed the then effective Warrant Price, (ii) not amend or modify any provision of the Certificate of Incorporation or by-laws of the Issuer in any manner that would adversely affect the rights of the Holders of the Warrants, (iii) take all such action as may be reasonably necessary in order that the Issuer may validly and legally issue fully paid and nonassessable shares of Common Stock, free and clear of any liens, claims, encumbrances and restrictions (other than as provided herein) upon the exercise of this Warrant, and (iv) use its best efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be reasonably necessary to enable the Issuer to perform its obligations under this Warrant.

(a) Recapitalization, Reorganization, Reclassification, Consolidation, Merger or Sale.

(i) In case the Issuer after the Original Issue Date shall do any of the following (each, a “Triggering Event”): (a) consolidate with or merge into any other Person and the Issuer shall not be the continuing or surviving corporation of such consolidation or merger, or (b) permit any other Person to consolidate with or merge into the Issuer and the Issuer shall be the continuing or surviving Person but, in connection with such consolidation or merger, any Capital Stock of the Issuer shall be changed into or exchanged for Securities of any other Person or cash or any other property, or (c) transfer all or substantially all of its properties or assets to any other Person, or (d) effect a capital reorganization or reclassification of its Capital Stock, then, and in the case of each such Triggering Event, proper provision shall be made so that, upon the basis and the terms and in the manner provided in this Warrant, the Holder of this Warrant shall be entitled upon the exercise hereof at any time after the consummation of such Triggering Event, to the extent this Warrant is not exercised prior to such Triggering Event, to receive at the Warrant Price in effect at the time immediately prior to the

-6-


	consummation of such Triggering Event in lieu of the Common Stock issuable upon such exercise of this Warrant prior to such Triggering Event, the Securities, cash and property to which such Holder would have been entitled upon the consummation of such Triggering Event if such Holder had exercised the rights represented by this Warrant immediately prior thereto (including the right to elect the type of consideration, if applicable), subject to adjustments (subsequent to such corporate action) as nearly equivalent as possible to the adjustments provided for elsewhere in this Section 4. In the event that the surviving entity in any such Triggering Event is not a public company under the Securities Exchange Act of 1934, the common equity securities of which are traded or quoted on a national securities exchange or the OTC Bulletin Board (a “Qualifying Entity”), then the Holder, at its option, shall be permitted to require that the Company pay to the Holder an amount equal to the Black-Scholes value of this Warrant.

	(ii) Notwithstanding anything contained in this Warrant to the contrary and so long as the surviving entity is a Qualifying Entity, the Issuer will not be deemed to have effected any Triggering Event if, prior to the consummation thereof, each Person (other than the Issuer) which may be required to deliver any Securities, cash or property upon the exercise of this Warrant as provided herein shall assume, by written instrument delivered to the Holder of this Warrant and reasonably satisfactory to the Holder, (A) the obligations of the Issuer under this Warrant (and if the Issuer shall survive the consummation of such Triggering Event, such assumption shall be in addition to, and shall not release the Issuer from, any continuing obligations of the Issuer under this Warrant) and (B) the obligation to deliver to such Holder such shares of Securities, cash or property as, in accordance with the foregoing provisions of this subsection (a), such Holder shall be entitled to receive, and such Person shall have similarly delivered to such Holder an opinion of counsel for such Person stating that this Warrant shall thereafter continue in full force and effect and the terms hereof (including, without limitation, all of the provisions of this subsection (a)) shall be applicable to the Securities, cash or property which such Person may be required to deliver upon any exercise of this Warrant or the exercise of any rights pursuant hereto.

(b) Stock Dividends, Subdivisions and Combinations. If at any time the Issuer shall:


	(i) set a record date or take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend payable in, or other distribution of, Additional Shares of Common Stock,

	(ii) subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock, or

	(iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock,

-7-


	(i) cash (other than a cash dividend payable out of earnings or earned surplus legally available for the payment of dividends under the laws of the jurisdiction of incorporation of the Issuer),

	(ii) any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash, Common Stock Equivalents, Additional Shares of Common Stock or Permitted Issuances), or

	(iii) any warrants or other rights to subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash, Common Stock Equivalents, Additional Shares of Common Stock or Permitted Issuances),

-8-

reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding shares of Common Stock within the meaning of Section 4(b).

(d) Issuance of Additional Shares of Common Stock.


	(i) In the event the Issuer shall at any time following the Original Issue Date and prior to a Release Event (as defined below) issue any Additional Shares of Common Stock (otherwise than as provided in the foregoing subsections (a) through (c) of this Section 4), at a price per share less than the Warrant Price then in effect or without consideration, then the Warrant Price upon each such issuance shall be adjusted to the price equal to the consideration per share paid for such Additional Shares of Common Stock. Upon and after a Release Event, the price shall be adjusted to the price (rounded to the nearest cent) determined by multiplying the Warrant Price by a fraction:

		(A) the numerator of which shall be equal to the sum of (x) the number of shares of Outstanding Common Stock immediately prior to the issuance of such Additional Shares of Common Stock plus (y) the number of shares of Common Stock (rounded to the nearest whole share) which the aggregate consideration for the total number of such Additional Shares of Common Stock so issued would purchase at a price per share equal to the Warrant Price then in effect, and

		(B) the denominator of which shall be equal to the number of shares of Outstanding Common Stock immediately after the issuance of such Additional Shares of Common Stock.

	(ii) No adjustment of the Warrant Price shall be made under paragraph (i) of Section 4(d) upon the issuance of any Additional Shares of Common Stock which are issued pursuant to the exercise or conversion of any Common Stock Equivalents if any such adjustment shall previously have been made upon the issuance of such Common Stock Equivalents, or upon the issuance of any warrant or other rights therefor pursuant to Sections 4(e) or 4(f), or in connection with any Permitted Issuances. The term “Release Event” means, with respect to the holder’s Warrant Stock, the date on which the Company files a Form 8-K with the Commission disclosing the Company’s receipt of written notice from the U.S. Food and Drug Administration regarding the granting the Issuer the right to commercialize and market (i.e., formal approval of the Issuer’s Pre-Market Application for) its OrCel product for the treatment of venous leg ulcers.

-9-

Price then in effect immediately prior to the time of such issue or sale, shall be adjusted to the price equal to the Warrant Consideration per share for which Common Stock is issuable upon the exercise of such warrant or option. Upon and after a Release Event, this right shall cease. In the event the Issuer shall at any time following a Release Event issue any warrants or options at a price per share less than the Warrant Price then in effect or without consideration, the price shall be adjusted to the price (rounded to the nearest cent) determined by multiplying the Warrant Price by a fraction: (1) the numerator of which shall be equal to the sum of (A) the number of shares of Common Stock outstanding immediately prior to the issuance or sale of such warrants or options plus (B) the number of shares of Common Stock (rounded to the nearest whole share) which the Warrant Consideration multiplied by the number of shares of Common Stock issuable upon the exercise or conversion of all such warrants or options, would purchase at a price per share equal to the Warrant Price then in effect, and (2) the denominator of which shall be equal to the number of shares of Common Stock that would be outstanding assuming the exercise or conversion of all such warrants and options. No adjustments of the Warrant Price then in effect shall be made upon the actual issue of such Common Stock or of such Common Stock Equivalents upon exercise of such warrants or other rights or upon the actual issue of such Common Stock upon such conversion or exchange of such Common Stock Equivalents. No adjustments of the Warrant Price shall be made under this Section 4(e) in connection with any Permitted Issuances.

(f) Issuance of Common Stock Equivalents. If at any time prior to a Release Event the Issuer shall take a record of the Holders of its Common Stock for the purpose of entitling them to receive a distribution of, or shall in any manner (whether directly or by assumption in a merger in which the Issuer is the surviving corporation) issue or sell, any Common Stock Equivalents, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the Common Stock Equivalent Consideration (hereafter defined) per share for which Common Stock is issuable upon such conversion or exchange shall be less than the Warrant Price in effect immediately prior to the time of such issue or sale, or if, after any such issuance of Common Stock Equivalents, the price per share for which Additional Shares of Common Stock may be issuable thereafter is amended or adjusted, and such price as so amended shall be less than the applicable Conversion Price in effect at the time of such amendment or adjustment, then the Warrant Price then in effect immediately prior to the time of such issue or sale, shall upon each such issuance or sale be adjusted to the price equal to the Common Stock Equivalent Consideration per share paid for such Common Share Equivalents. Upon and after a Release Event, this right shall cease. In the event the Issuer shall at any time following a Release Event issue any Common Stock Equivalents for Common Stock Equivalent Consideration per share less than the Warrant Price then in effect or without consideration, then the Warrant Price upon each such issuance shall be adjusted to that price (rounded to the nearest cent) determined by multiplying the Warrant Price by a fraction: (1) the numerator of which shall be equal to the sum of (A) the number of shares of Common Stock outstanding immediately prior to the issuance or sale of such Common Stock Equivalents plus (B) the number of shares of Common Stock (rounded to the nearest whole share) which the Common Stock Equivalent Consideration multiplied by the number of shares of Common Stock issuable upon the exercise or conversion of all such Common Stock Equivalents, would purchase at a price per share equal to the Warrant Price then in effect, and (2) the denominator of which shall be equal to the number of shares of

-10-

Common Stock that would be outstanding assuming the exercise or conversion of all such Common Stock Equivalents. No further adjustment of the Warrant Price then in effect shall be made under this Section 4(f) upon the issuance of any Common Stock Equivalents which are issued pursuant to the exercise of any warrants or other subscription or purchase rights therefor, if any such adjustment shall previously have been made upon the issuance of such warrants or other rights pursuant to Section 4(e). No further adjustments of the Warrant Price then in effect shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Common Stock Equivalents. No adjustments of the Warrant Price shall be made under this Section 4(f) in connection with any Permitted Issuances.

(g) Superseding Adjustment. If, at any time after any adjustment of the Warrant Price then in effect shall have been made pursuant to Section 4(e) or Section 4(f) as the result of any issuance of warrants, other rights or Common Stock Equivalents, and (i) such warrants or other rights, or the right of conversion or exchange in such other Common Stock Equivalents, shall expire, and all or a portion of such warrants or other rights, or the right of conversion or exchange with respect to all or a portion of such other Common Stock Equivalents, as the case may be shall not have been exercised, or (ii) the consideration per share for which shares of Common Stock are issuable pursuant to such Common Stock Equivalents, shall be increased solely by virtue of provisions therein contained for an automatic increase in such consideration per share upon the occurrence of a specified date or event, then for each outstanding Warrant such previous adjustment shall be rescinded and annulled and the Additional Shares of Common Stock which were deemed to have been issued by virtue of the computation made in connection with the adjustment so rescinded and annulled shall no longer be deemed to have been issued by virtue of such computation. Upon the occurrence of an event set forth in this Section 4(g) above, there shall be a recomputation made of the effect of such Common Stock Equivalents on the basis of: (i) treating the number of Additional Shares of Common Stock or other property, if any, theretofore actually issued or issuable pursuant to the previous exercise of any such warrants or other rights or any such right of conversion or exchange, as having been issued on the date or dates of any such exercise and for the consideration actually received and receivable therefor, and (ii) treating any such Common Stock Equivalents which then remain outstanding as having been granted or issued immediately after the time of such increase of the consideration per share for which shares of Common Stock or other property are issuable under such Common Stock Equivalents; whereupon a new adjustment of the Warrant Price then in effect shall be made, which new adjustment shall supersede the previous adjustment so rescinded and annulled.

-11-

outstanding immediately after such purchase, redemption or acquisition. For the purposes of this subsection (h), the date as of which the Per Share Market Price shall be computed shall be the earlier of (x) the date on which the Issuer shall enter into a firm contract for the purchase, redemption or acquisition of such Common Stock, or (y) the date of actual purchase, redemption or acquisition of such Common Stock. For the purposes of this subsection (h), a purchase, redemption or acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the underlying Common Stock, and the computation herein required shall be made on the basis of the full exercise, conversion or exchange of such Common Stock Equivalent on the date as of which such computation is required hereby to be made, whether or not such Common Stock Equivalent is actually exercisable, convertible or exchangeable on such date.

(i) Computation of Consideration. To the extent that any Additional Shares of Common Stock or any Common Stock Equivalents (or any warrants or other rights therefor) shall be issued for cash consideration, the consideration received by the Issuer therefor shall be the amount of the cash received by the Issuer therefor, or, if such Additional Shares of Common Stock or Common Stock Equivalents are offered by the Issuer for subscription, the subscription price, or, if such Additional Shares of Common Stock or Common Stock Equivalents are sold to underwriters or dealers for public offering without a subscription offering, the initial public offering price (in any such case subtracting any amounts paid or receivable for accrued interest or accrued dividends and without taking into account any compensation, discounts or expenses paid or incurred by the Issuer for and in the underwriting of, or otherwise in connection with, the issuance thereof). To the extent that such issuance shall be for a consideration other than cash, then, except as herein otherwise expressly provided, the amount of such consideration shall be deemed to be the fair value of such consideration at the time of such issuance as mutually determined in good faith by the Board of Directors of the Issuer and the Majority Holders. The consideration for any Additional Shares of Common Stock issuable pursuant to any warrants or other rights to subscribe for or purchase the same shall be the consideration received by the Issuer for issuing such warrants or other rights divided by the number of shares of Common Stock issuable upon the exercise of such warrant or right plus the additional consideration payable to the Issuer upon exercise of such warrant or other right for one share of Common Stock (together the “Warrant Consideration”). The consideration for any Additional Shares of Common Stock issuable pursuant to the terms of any Common Stock Equivalents shall be the consideration received by the Issuer for issuing such Common Stock Equivalent, divided by the number of shares of Common Stock issuable upon the conversion or other exercise of such Common Stock Equivalent, plus the additional consideration, if any, payable to the Issuer upon the exercise of the right of conversion or exchange in such Common Stock Equivalent for one share of Common Stock (together the “Common Stock Equivalent Consideration”). In case of the issuance at any time of any Additional Shares of Common Stock or Common Stock Equivalents in payment or satisfaction of any

-12-


	dividends upon any class of stock other than Common Stock, the Issuer shall be deemed to have received for such Additional Shares of Common Stock or Common Stock Equivalents a consideration equal to the amount of such dividend so paid or satisfied.

	(ii) No Adjustments of Number of Shares. No adjustment of the number of shares of Common Stock for which this Warrant shall be exercisable shall be made because of any adjustments of the Warrant Price pursuant to Sections (d), (e), (f), (g) and (h) of this Section 4.

	(iii) Fractional Interests. In computing adjustments under this Section 4, fractional interests in Common Stock shall be taken into account to the nearest one one-hundredth (1/100^th) of a share.

	(iv) When Adjustment Not Required. If the Issuer shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or distribution or subscription or purchase rights and shall, thereafter and before the distribution to stockholders thereof, legally abandon its plan to pay or deliver such dividend, distribution, subscription or purchase rights, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

-13-

the Issuer shall have ten (10) days after receipt of notice from such Holder of its selection of such firm to object thereto, in which case such Holder shall select another such firm and the Issuer shall have no such right of objection. The firm selected by the Holder of this Warrant as provided in the preceding sentence shall be instructed to deliver a written opinion as to such matters to the Issuer and such Holder within thirty (30) days after submission to it of such dispute. Such opinion shall be final and binding on the parties hereto.

The Registration Statement shall be on Form SB-2 (except if the Company is not then eligible to register for resale the Registrable Securities on Form SB-2, in which case such registration shall be on another appropriate form in accordance with the Securities Act and the rules promulgated thereunder). The Company shall (i) not permit any securities other than the Registrable Securities and the securities listed on Schedule II hereto (the “Other Securities”) to be included in the Registration Statement and (ii) use its best efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as possible after the filing thereof, but in any event prior to the Effectiveness Date, and to keep such Registration Statement continuously effective under the Securities Act until such date as is the earliest of (x) the date when all Registrable Securities covered by such Registration Statement have been sold, (y) the date on which all the Registrable Securities may be sold without any restriction pursuant to Rule 144(k), as determined by the counsel to the Company pursuant to a written opinion letter, addressed to the Company’s transfer agent to such effect, or (z) two (2) years following the Effectiveness Date (the “Effectiveness Period”).

-4-

Stock issuable upon exercise of the Series M-1 Warrants and upon conversion of the Series D-2 Preferred Stock if issued and outstanding at the time of filing of the Registration Statement registered on a pro rata basis among the holders thereof.

For purposes of this Section 2(b), “Effectiveness Date” means with respect to each subsequent Registration Statement filed pursuant hereto, the earlier of (A) the ninetieth (90^th) day following the filing date of such Registration Statement (or in the event such Registration Statement receives a “full review” by the Commission, the one hundred twentieth (120^th) day following such filing date) or (B) the date which is within three (3) Business Days after the date on which the Commission informs the Company (i) that the Commission will not review such Registration Statement or (ii) that the Company may request the acceleration of the effectiveness of such Registration Statement and the Company makes such request; provided that, if the Effectiveness Date falls on a Saturday, Sunday or any other day which shall be a legal holiday or a day on which the Commission is authorized or required by law or other government actions to close, the Effectiveness Date shall be the following Business Day.

3. Registration Procedures.

In connection with the Company’s registration obligations hereunder, the Company shall:

(a) Prepare and file with the Commission on or prior to the Filing Date, a Registration Statement on Form SB-2 (or if the Company is not then eligible to register for resale the Registrable Securities on Form SB-2 such registration shall be on another appropriate form in accordance with the Securities Act and the rules promulgated thereunder) in accordance with the method or methods of distribution thereof as specified by the Holders (except if otherwise directed by the Holders), and cause the Registration Statement to become effective and remain effective as provided herein; provided, however, that not less than five (5) Business Days prior to the filing of the Registration Statement or any related Prospectus or any amendment or supplement thereto (including any document that would be incorporated therein by reference), the Company shall (i) furnish to the Holders (as requested) and the Special Counsel, copies of all such documents proposed to be filed, which documents (other than those incorporated by reference) will be subject to the review of such Holders (as requested) and such Special Counsel, and (ii) cause its officers and directors, counsel and independent certified public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of such Special Counsel, to conduct a reasonable investigation within the meaning of the Securities Act. The

-5-

Company shall not file the Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Special Counsel shall reasonably object in writing within three (3) Business Days of their receipt thereof. If the Special Counsel shall so reasonably object in writing, the Filing Date and Effectiveness Date shall be extended by the time that the Company and the Special Counsel shall reasonably need to respond to and/or comply with such objections.

(b) (i) Prepare and file with the Commission such amendments, including post-effective amendments, to the Registration Statement as may be necessary to keep the Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; (iii) respond as promptly as possible to any comments received from the Commission with respect to the Registration Statement or any amendment thereto and as promptly as possible provide the Special Counsel and Holders (as requested) true and complete copies of all correspondence from and to the Commission relating to the Registration Statement; and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by the Registration Statement during the applicable period in accordance with the intended methods of disposition by the Holders thereof set forth in the Registration Statement as so amended or in such Prospectus as so supplemented.

(c) Notify the Holders (as requested) and the Special Counsel as promptly as possible (and, in the case of (i)(A) below, not less than five (5) days prior to such filing) and (if requested by any such Person) confirm such notice in writing no later than one (1) Business Day following the day (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to the Registration Statement is filed; (B) when the Commission notifies the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration Statement and (C) with respect to the Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission or any other Federal or state governmental authority for amendments or supplements to the Registration Statement or Prospectus or for additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) if at any time any of the representations and warranties of the Company contained in any agreement contemplated hereby ceases to be true and correct in all material respects; (v) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (vi) of the occurrence of any event that makes any statement made in the Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to the Registration Statement, Prospectus or other documents so that, in the case of the Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make

-6-

the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) Use its best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of, (i) any order suspending the effectiveness of the Registration Statement or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

(e) If requested by the Special Counsel or by the Majority Holders (i) promptly incorporate in a Prospectus supplement or post-effective amendment to the Registration Statement such information as the Company reasonably agrees should be included therein and (ii) make all required filings of such Prospectus supplement or such post-effective amendment as soon as practicable after the Company has received notification of the matters to be incorporated in such Prospectus supplement or post-effective amendment.

(f) Furnish to the Special Counsel and upon request to each Holder, without charge, at least one conformed copy of each Registration Statement and each amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference, and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission.

(g) Promptly deliver to the Special Counsel and each Holder, without charge, as many copies of the Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request; and the Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(h) Prior to any public offering of Registrable Securities, use its best efforts to register or qualify or cooperate with the selling Holders and the Special Counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Holder requests in writing, to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by a Registration Statement; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject or subject the Company to any material tax in any such jurisdiction where it is not then so subject.

(i) Cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold pursuant to a Registration Statement, which certificates shall be free of all restrictive legends (provided that the issuance of such unlegended certificates is in compliance with applicable securities laws), and to enable such

-7-

Registrable Securities to be in such denominations and registered in such names as any Holder may request at least three (3) Business Days prior to any sale of Registrable Securities.

(j) Upon the occurrence of any event contemplated by Section 3(c)(vi), as promptly as possible, prepare a supplement or amendment, including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither the Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(k) Use its best efforts to cause all Registrable Securities relating to such Registration Statement to be listed or traded on the OTC Bulletin Board, The Nasdaq SmallCap Market, or any other securities exchange, quotation system or market, if any, on which similar securities issued by the Company are then listed as and when required pursuant to the Purchase Agreement and the Exchange Agreement.

(l) Comply in all material respects with all applicable rules and regulations of the Commission and make generally available to its security holders earning statements satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 not later than 45 days after the end of any 3-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) commencing on the first day of the first fiscal quarter of the Company after the effective date of the Registration Statement, which statement shall conform to the requirements of Rule 158.

(m) The Company may require each selling Holder to furnish to the Company information regarding such Holder and the distribution of such Registrable Securities as is required by law to be disclosed in the Registration Statement, and the Company may exclude from such registration the Registrable Securities of any such Holder who unreasonably fails to furnish such information within a reasonable time after receiving such request.

If the Registration Statement refers to any Holder by name or otherwise as the holder of any securities of the Company, then such Holder shall have the right to require (if such reference to such Holder by name or otherwise is not required by the Securities Act or any similar federal statute then in force) the deletion of the reference to such Holder in any amendment or supplement to the Registration Statement filed or prepared subsequent to the time that such reference ceases to be required.

Each Holder covenants and agrees that (i) it will not sell any Registrable Securities under the Registration Statement until it has received copies of the Prospectus as then amended or supplemented as contemplated in Section 3(g) and notice from the Company that such Registration Statement and any post-effective amendments thereto have become effective as contemplated by Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will comply with the prospectus delivery requirements of the Securities Act as applicable to them in connection with sales of Registrable Securities pursuant to the Registration Statement.

-8-

Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(v), 3(c)(vi) or 3(n), such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder’s receipt of the copies of the supplemented Prospectus and/or amended Registration Statement contemplated by Section 3(j), or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement.

(n) If (i) there is material non-public information regarding the Company which the Company’s Board of Directors (the “Board”) reasonably determines not to be in the Company’s best interest to disclose and which the Company is not otherwise required to disclose, or (ii) there is a significant business opportunity (including, but not limited to, the acquisition or disposition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer or other similar transaction) available to the Company which the Board reasonably determines not to be in the Company’s best interest to disclose, then the Company may postpone or suspend filing or effectiveness of a registration statement for a period not to exceed twenty (20) consecutive days, provided that the Company may not postpone or suspend its obligation under this Section 3(n) for more than forty-five (45) days in the aggregate during any twelve (12) month period; provided, however, that no such postponement or suspension shall be permitted for consecutive twenty (20) day periods, arising out of the same set of facts, circumstances or transactions.

5. Indemnification.

(a) Indemnification by the Company.

The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement.

(b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, the directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final judgment not subject to appeal or review), as incurred, arising solely out of or based solely upon any untrue statement of a material fact contained in the Registration Statement, any Prospectus, or any form of prospectus, or arising solely out of or based solely upon any omission of a material fact required to be stated

-10-

therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, to the extent, but only to the extent, that such untrue statement or omission is contained in any information so furnished in writing by such Holder to the Company specifically for inclusion in the Registration Statement or such Prospectus and that such information was reasonably relied upon by the Company for use in the Registration Statement, such Prospectus or such form of prospectus or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of Prospectus. Notwithstanding anything to the contrary contained herein, the Holders shall be liable under this Section 5(b) for only that amount as does not exceed the lesser of (i) the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation and (ii) the aggregate purchase price paid by the Holder (other than PRF) for the Shares pursuant to the Purchase Agreement or, in the case of PRF, the stated value of the Series A-1 Preferred Stock and Series A-2 Preferred stock purchased by PRF pursuant to the Exchange Agreement.

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party promptly shall notify the Person from whom indemnity is sought (the “Indemnifying Party) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel (which shall be reasonably acceptable to the Indemnifying Party) that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel, reasonably acceptable to the Indemnifying Party, at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld or delayed. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any

-11-

pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten (10) Business Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

(d) Contribution. If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or refusal of a governmental authority to enforce such indemnification in accordance with its terms (by reason of public policy or otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 5(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. In no event shall any selling Holder be required to contribute an amount under this Section 5(d) in excess of the net proceeds received by such Holder upon sale of such Holder’s Registrable Securities pursuant to the Registration Statement giving rise to such contribution obligation.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

6. Rule 144.

As long as any Holder owns any Registrable Securities or securities entitling the Holder to acquire Registrable Securities, the Company covenants 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 Section 13(a) or 15(d) of the Exchange Act and, at the Holder’s request, to promptly furnish the Holders with true and complete copies of all such filings. As long as any Holder owns Registrable Securities or securities entitling the Holder to acquire Registrable Securities, if the Company is not required to file reports pursuant to Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the Holder, at the Holder’s request, and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act annual and quarterly financial statements, together with a discussion and analysis of such financial statements in form and substance substantially similar to those that would otherwise be required to be included in reports required by Section 13(a) or 15(d) of the Exchange Act, as well as any other information required thereby, in the time period that such filings would have been required to have been made under the Exchange Act. The Company further covenants that it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Person to sell its Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal opinions relating to such sale pursuant to Rule 144. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

7. Miscellaneous.

(a) Remedies. In the event of a breach by the Company or by a Holder, of any of their obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(b) No Inconsistent Agreements. Neither the Company nor any of its subsidiaries has, as of the date hereof entered into and currently in effect, nor shall the Company or any of its subsidiaries, on or after the date of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Except as disclosed in Section 2.1(c) of the Purchase Agreement or Section 2.1(c) of the Exchange Agreement, neither the Company nor any of its subsidiaries has previously entered into any agreement currently in effect granting any registration rights with respect to any of its securities to any Person. Without limiting the generality of the foregoing, without the written consent of the Holders of a majority of the then outstanding Registrable Securities, the Company shall not grant to any Person the

-13-

right to request the Company to register any securities of the Company under the Securities Act unless the rights so granted are subject in all respects to the prior rights in full of the Holders set forth herein, and are not otherwise in conflict with the provisions of this Agreement.

(c) No Piggyback on Registrations. Neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto or as disclosed in Section 2.1(c) of the Purchase Agreement, Section 2.1(c) of the Exchange Agreement or Schedule II hereto) may include securities of the Company in the Registration Statement and the Company shall not after the date hereof enter into any agreement providing such right to any of its securityholders, unless the rights so granted are subject in all respects to the prior rights in full of the Holders set forth herein, and are not otherwise in conflict with the provisions of this Agreement.

(d) Piggy-Back Registrations. If at any time when there is not an effective Registration Statement covering the Registrable Securities, the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, the Company shall send to each Holder written notice of such determination and, if within thirty (30) days after receipt of such notice, any such Holder shall so request in writing, (which request shall specify the Registrable Securities intended to be disposed of by such Holder), the Company will cause the registration under the Securities Act of all Registrable Securities which the Company has been so requested to register by the Holder, to the extent requisite to permit the disposition of the Registrable Securities so to be registered, provided that if at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company may, at its election, give written notice of such determination to such holder and, thereupon, (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from its obligation to pay expenses in accordance with Section 4 hereof), and (ii) in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities being registered pursuant to this Section 7(d) for the same period as the delay in registering such other securities. The Company shall include in such registration statement all or any part of such Registrable Securities such Holder requests to be registered; provided, however, that the Company shall not be required to register any Registrable Securities pursuant to this Section 7(d) that are eligible for sale pursuant to Rule 144(k) of the Securities Act. In the case of an underwritten public offering, if the managing underwriter(s) or underwriter(s) should reasonably object to the inclusion of the Registrable Securities in such registration statement, then if the Company after consultation with the managing underwriter should reasonably determine that the inclusion of such Registrable Securities, would materially adversely affect the offering contemplated in such registration statement, and based on such determination recommends inclusion in such registration statement of fewer or none of the Registrable Securities of the Holders, then the number of Registrable Securities of the Holders included in

-14-

such registration statement shall be reduced pro-rata among such Holders (based upon the number of Registrable Securities requested to be included in the registration statement), if the Company after consultation with the underwriter(s) recommends the inclusion of fewer Registrable Securities; provided, however, that such reduction shall not represent a greater fraction of the number of Registrable Securities intended to be offered by the Holders than the fraction of similar reductions imposed on such other persons or entities (including the Company).

(e) Failure to File Registration Statement and Other Events. The Company and the Holders agree that the Holders will suffer damages if the Registration Statement is not filed on or prior to the Filing Date and not declared effective by the Commission on or prior to the Effectiveness Date and maintained in the manner contemplated herein during the Effectiveness Period or if certain other events occur. The Company and the Holders further agree that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if (A) (i) the Registration Statement is not filed on or prior to the Filing Date or (ii) is not declared effective by the Commission on or prior to the thirtieth (30^th) day following the Effectiveness Date, or (B) the Company fails to file with the Commission a request for acceleration in accordance with Rule 461 promulgated under the Securities Act within three (3) Business Days of the date that the Company is notified (orally or in writing, whichever is earlier) by the Commission that a Registration Statement will not be “reviewed,” or not subject to further review, or (C) the Registration Statement is filed with and declared effective by the Commission but thereafter ceases to be effective as to all Registrable Securities included therein at any time prior to the expiration of the Effectiveness Period, without being succeeded immediately by a subsequent Registration Statement filed with and declared effective by the Commission, or (D) trading in the Common Stock shall hereafter be suspended or if the Common Stock is hereafter delisted from the OTC Bulletin Board (or other principal exchange on which the Common Stock is traded) for any reason for more than three (3) Business Days in the aggregate, or (E) the Company breaches in a material respect any covenant or other material term or condition to this Agreement, the Purchase Agreement (other than a representation or warranty contained therein), the Exchange Agreement (other than a representation or warranty contained therein) or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated hereby and thereby, and such breach continues for a period of thirty (30) days after written notice thereof to the Company, or (F) the Company has breached Section 3(n) (any such failure or breach being referred to as an “Event,” and for purposes of clauses (A) and (D) the date on which such Event occurs, or for purposes of clause (B) the date on which such three (3) Business Day period is exceeded, or for purposes of clause (C) after more than fifteen (15) Business Days, or for purposes of clause (D) the date on which such three (3) Business Day period is exceeded, or for clause (E) the date on which such thirty (30) day period is exceeded, or for clause (F) the date the Company has breached Section 3(n) hereof, being referred to as “Event Date”), the Company shall pay in cash as liquidated damages to each Holder only with respect to the Series A Convertible Preferred Stock and Series A-1 Convertible Preferred Stock held by such Holder in an amount equal to (x) solely in the case of clause (A)(i) two percent (2%) of the Holders’ initial investment in the Series A Convertible Preferred Stock and the stated value of the Series A-1 Convertible Preferred Stock (provided, however, that in the case of clause (A)(i), the Event shall be deemed to commence on the sixtieth (60) day prior to the Event Date), and (y) in all other cases, one percent (1.0%) for each thirty (30) day period thereafter or portion thereof of the Holder’s initial investment in the Series A

-15-

Convertible Preferred Stock and the stated value of the Series A-1 Convertible Preferred Stock from the Event Date until the earlier of (x) the date when the applicable Event has been cured, or (y) when the Effectiveness Period ends, which shall be pro rated for such periods less than thirty (30) days (the “Periodic Amount”); provided, however, that in no event shall the amount of liquidated damages payable at any time and from time to time to any Holder pursuant to this Section 7(e) exceed an aggregate of twenty-four percent (24%) of the amount of the Holder’s initial investment in the Series A Convertible Preferred Stock and the stated value of the Series A-1 Convertible Preferred Stock; and provided, further, that in the event the Commission does not permit all of the Registrable Securities to be included in the Registration Statement because of its application of Rule 415, liquidated damages payable pursuant to clause (A)(ii) above shall be payable by the Company based on one percent (1%) of the portion of the Holder’s initial investment in the Series A Convertible Preferred Shares and the stated value of the Series A-1 Convertible Preferred Stock that corresponds to the number of such Holder’s Registrable Securities permitted to be registered by the Commission pursuant to Rule 415. Notwithstanding anything to the contrary in this paragraph (e), if (a) any of the Events described in clauses (A), (B), (C), (D) or (F) shall have occurred, (b) on or prior to the applicable Event Date, the Company shall have exercised its rights under Section 3(n) hereof and (c) the postponement or suspension permitted pursuant to such Section 3(n) shall remain effective as of such applicable Event Date, then the applicable Event Date shall be deemed instead to occur on the second Business Day following the termination of such postponement or suspension. Liquidated damages payable by the Company pursuant to this Section 7(e) shall be payable on the first (1^st) Business Day of each thirty (30) day period following the Event Date. Notwithstanding anything to the contrary contained herein, in no event shall any liquidated damages be payable with respect to the Warrants or the Warrant Shares. The parties agree that the Periodic Amount represents a reasonable estimate on the part of the parties, as of the date of this Agreement, of the amount of damages that may be incurred by the Holders if the Registration Statement is not filed on or prior to the Filing Date or has not been declared effective by the Commission on or prior to the Effectiveness Date and maintained in the manner contemplated herein during the Effectiveness Period or if any other Event as described herein has occurred.

(f) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and the Majority Holders. Notwithstanding anything herein to the contrary, (i) no amendment, modification, supplement, or waiver of or consent to a departure from the first sentence of Section 2(b) hereof shall adversely effect PRF’s rights without the written consent of PRF, (ii) liquidated damages payable by the Company pursuant to Section 7(e) hereof shall not be waived or modified unless the same waiver or modification is applied to all holders of the Series A Preferred Stock and Series A-1 Preferred Stock and (iii) no other amendment, modification, supplement, waiver or consent shall apply to the holders of the Series A-1 Preferred Stock or Series A-2 Preferred Stock unless it also applies to all holders of the Series A Preferred Stock. No consideration shall be offered or paid to any person to amend, modify, supplement, waive or consent to a departure from any provision hereof unless the same consideration is also offered to all Holders. All Holders shall be notified by the Company of any request for an amendment, modification, supplement, waiver or consent concurrently.

-16-

(g) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earlier of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified for notice prior to 5:00 p.m., New York City time, on a Business Day, (ii) the Business Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified for notice later than 5:00 p.m., New York City time, on any date and earlier than 11:59 p.m., New York City time, on such date, (iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service or (iv) actual receipt by the party to whom such notice is required to be given.

(g) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns and shall inure to the benefit of each Holder and its successors and assigns. The Company may not assign this Agreement or any of its rights or obligations hereunder without the prior written consent of each Holder, except that the assumption of the Company’s obligations by the surviving company in a merger of the Company with and into such surviving company, shall not constitute an assignment of the Company’s obligations or rights hereunder. Each Purchaser may assign its rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement and PRF may assign its rights hereunder in the manner and to the persons permitted under the Exchange Agreement.

(h) Assignment of Registration Rights. The rights of each Holder hereunder, including the right to have the Company register for resale Registrable Securities in accordance with the terms of this Agreement, shall be automatically assignable by each Holder to any Affiliate of such Holder or any other Holder or Affiliate of any other Holder of the Registrable Securities if: (i) the Holder agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights are being transferred or assigned, (iii)

-17-

following such transfer or assignment the further disposition of such securities by the transferee or assignees is restricted under the Securities Act and applicable state securities laws, (iv) at or before the time the Company receives the written notice contemplated by clause (ii) of this Section, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions of this Agreement, (v) such transfer by a Purchaser shall have been made in accordance with the applicable requirements of the Purchase Agreement and (vi) such transfer by PRF shall be in accordance with the Exchange Agreement. In addition, each Holder shall have the right to assign its rights hereunder to any other Person with the prior written consent of the Company, which consent shall not be unreasonably withheld. The rights to assignment shall apply to the Holders (and to subsequent) successors and assigns.

(i) Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature were the original thereof.

(j) Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York, without giving effect to any of the conflicts of law principles which would result in the application of the substantive law of another jurisdiction. This Agreement shall not be interpreted or construed with any presumption against the party causing this Agreement to be drafted. The Company and the Holders agree that venue for any dispute arising under this Agreement will lie exclusively in the state or federal courts located in New York County, New York, and the parties irrevocably waive any right to raise forum non conveniens or any other argument that New York is not the proper venue. The Company and the Holders irrevocably consent to personal jurisdiction in the state and federal courts of the state of New York. The Company and the Holders consent to process being served in any such suit, action or proceeding by delivering a copy thereof to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing in this Section 7(j) shall affect or limit any right to serve process in any other manner permitted by law. The Company and the Holders hereby agree that the prevailing party in any suit, action or proceeding arising out of or relating to this Agreement, the Purchase Agreement or the Exchange Agreement, shall be entitled to reimbursement for reasonable legal fees from the non-prevailing party. The parties hereby waive all rights to a trial by jury.

(k) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any remedies provided by law.

(l) Severability. If any term, provision, covenant or restriction of this Agreement is held to be invalid, illegal, void or unenforceable in any respect, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or

-18-

restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(m) Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.

(n) Shares Held by the Company and its Affiliates. Whenever the consent or approval of Holders of a specified percentage of Registrable Securities is required hereunder, Registrable Securities held by the Company or its Affiliates (other than any Holder or transferees or successors or assigns thereof if such Holder is deemed to be an Affiliate solely by reason of its holdings of such Registrable Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

(o) Termination. This Agreement shall terminate on the date when all remaining Registrable Securities may be sold without restriction pursuant to paragraph (k) of Rule 144.

(o) Independent Nature of Purchasers and PRF. The Company acknowledges that the obligations of each Purchaser under the Transaction Documents and of PRF under the Exchange Agreement, this Agreement, and the Certificates of Designation of the Series A-1 Convertible Preferred Stock and the Series A-2 Convertible Preferred Stock (collectively, the “PRF Transaction Documents”) are several and not joint with the obligations of any other Purchaser or PRF, as the case may be, and no Purchaser nor PRF shall be responsible in any way for the performance of the obligations of any other Purchaser under the Transaction Documents or of PRF under the PRF Transaction Documents. The Company acknowledges that the decision of each Purchaser to purchase securities pursuant to the Purchase Agreement has been made by such Purchaser, and by PRF to exchange revenue interests for securities pursuant to the Exchange Agreement has been made by PRF, independently of any other purchase or exchange and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of its Subsidiaries which may have been made or given by any other Purchaser or PRF or by any agent or employee of any other Purchaser or PRF, and no Purchaser nor PRF nor any of their respective agents or employees shall have any liability to any other Purchaser or PRF (or any other person) relating to or arising from any such information, materials, statements or opinions. The Company acknowledges that nothing contained herein, or in any Transaction Document or PRF Transaction Document, and no action taken by any Purchaser or PRF pursuant hereto or thereto (including, but not limited to, the (i) inclusion of a Purchaser or PRF in the Registration Statement and (ii) review by, and consent to, such Registration Statement by a Purchaser or PRF) shall be deemed to constitute the Purchasers or PRF as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers and PRF are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents and the PRF Transaction Documents. The Company acknowledges that each Purchaser and PRF shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Documents and PRF

-19-

Transaction Documents, and it shall not be necessary for any other Purchaser or PRF to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that for reasons of administrative convenience only, the Transaction Documents and the PRF Transaction Documents have been prepared or reviewed by counsel for one of the Purchasers and separate counsel for PRF and neither of such counsel represents all of the Purchasers but only such Purchaser (in the case of Special Counsel) or PRF (in the case of PRF Counsel) and the other Purchasers have had the opportunity to retain their own individual counsel with respect to the transactions contemplated hereby. The Company acknowledges that it has elected to provide all Purchasers 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 the Purchasers. The Company acknowledges that such procedure with respect to the Transaction Documents and the PRF Transaction Documents in no way creates a presumption that the Purchasers and PRF are in any way acting in concert or as a group with respect to the Transaction Documents or PRF Transaction Documents or the transactions contemplated hereby or thereby.

EXHIBIT E to the
SERIES A CONVERTIBLE PREFERRED STOCK PURCHASE AGREEMENT FOR
ORTEC INTERNATIONAL, INC.

FORM OF IRREVOCABLE TRANSFER AGENT INSTRUCTIONS

ORTEC INTERNATIONAL, INC.

as of June 18, 2007

[Name and address of Transfer Agent]
Attn: _____________

Ladies and Gentlemen:

Reference is made to that certain Series A Convertible Preferred Stock Purchase Agreement, dated as of June 18, 2007, by and among Ortec International, Inc., a Delaware corporation (the “Company”), and the purchasers named therein (collectively, the “Purchasers”) pursuant to which the Company is issuing to the Purchasers shares of its Series A Convertible Preferred Stock, par value $.001 per share, (the “Preferred Shares”) and warrants (the “Warrants”) to purchase shares of the Company’s common stock, par value $.001 per share (the “Common Stock”) in connection with the sale and issuance of Preferred Shares and Warrants to the Purchasers. This letter shall serve as our irrevocable authorization and direction to you (provided that you are the transfer agent of the Company at such time) to issue shares of Common Stock upon conversion of the Preferred Shares (the “Conversion Shares”) and exercise of the Warrants (the “Warrant Shares”) to or upon the order of a Purchaser from time to time upon (i) surrender to you of a properly completed and duly executed Conversion Notice or Exercise Notice, as the case may be, in the form attached hereto as Exhibit I and Exhibit II, respectively, (ii) in the case of the conversion of Preferred Shares, a copy of the certificates (with the original certificates delivered to the Company) representing Preferred Shares being converted or, in the case of Warrants being exercised, a copy of the Warrants (with the original Warrants delivered to the Company) being exercised (or, in each case, an indemnification undertaking with respect to such share certificates or the warrants in the case of their loss, theft or destruction), and (iii) delivery of a treasury order or other appropriate order duly executed by a duly authorized officer of the Company. So long as you have previously received (x) written confirmation from counsel to the Company that a registration statement covering resales of the Conversion Shares or Warrant Shares, as applicable, has been declared effective by the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “1933 Act”), and no subsequent notice by the Company or its counsel of the suspension or termination of its effectiveness and (y) a copy of such registration statement, and if the Purchaser represents in writing that the Conversion Shares or the Warrant Shares, as the case may be, were sold pursuant to the Registration Statement, then certificates representing the Conversion Shares and the Warrant Shares, as the case may be, shall not bear any legend restricting transfer of the Conversion Shares and the Warrant Shares, as the case may be, thereby and should not be subject to any stop-transfer restriction. Provided, however, that if you have not previously received (i) written confirmation from counsel to the Company that a registration statement covering resales of the Conversion Shares or Warrant Shares, as applicable, has been declared effective by the SEC under the 1933 Act, and (ii) a copy of such registration statement, then the certificates for the Conversion Shares and the Warrant Shares shall bear the following legend:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS, OR ORTEC INTERNATIONAL, INC. SHALL HAVE RECEIVED AN OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.”

and, provided further, that the Company may from time to time notify you to place stop-transfer restrictions on the certificates for the Conversion Shares and the Warrant Shares in the event a registration statement covering the Conversion Shares and the Warrant Shares is subject to amendment for events then current or the prospectus which is part of such registration statement may no longer be used for sales of Conversion Shares or Warrant Shares.

A form of written confirmation from counsel to the Company that a registration statement covering resales of the Conversion Shares and the Warrant Shares has been declared effective by the SEC under the 1933 Act is attached hereto as Exhibit III.

Please be advised that the Purchasers are relying upon this letter as an inducement to enter into the Securities Purchase Agreement and, accordingly, each Purchaser is a third party beneficiary to these instructions.

Please execute this letter in the space indicated to acknowledge your agreement to act in accordance with these instructions. Should you have any questions concerning this matter, please contact me at ___________.

We are counsel to Ortec International, Inc., a Delaware corporation (the “Company”), and have represented the Company in connection with that certain Series A Convertible Preferred Stock Purchase Agreement (the “Purchase Agreement”), dated as of June 18, 2007, by and among the Company and the purchasers named therein (collectively, the “Purchasers”) pursuant to which the Company issued to the Purchasers shares of its Series A Convertible Preferred Stock, par value $.001 per share, (the “Preferred Shares”) and warrants (the “Warrants”) to purchase shares of the Company’s common stock, par value $.001 per share (the “Common Stock”). Pursuant to the Purchase Agreement, the Company agreed, among other things, to register the shares of Common Stock issuable upon conversion of the Preferred Shares and exercise of the Warrants (together the “Registrable Shares”), under the Securities Act of 1933, as amended (the “1933 Act”). In connection with the Company’s obligations under the Purchase Agreement, on ________________, 2007, the Company filed a Registration Statement on Form SB-2 (File No. 333-________) (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) relating to the resale of the Registrable Shares which names each of the present Purchasers as a selling stockholder thereunder.

In connection with the foregoing, we advise you that a member of the SEC’s staff has advised us by telephone that the SEC has entered an order declaring the Registration Statement effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after telephonic inquiry of a member of the SEC’s staff, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and accordingly, the Registrable Shares are available for resale under the 1933 Act pursuant to the Registration Statement.


	Very truly yours,

FORM OF OPINION OF COUNSEL

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the state of Delaware and has the requisite corporate power to own, lease and operate its properties and assets, and to carry on its business as presently conducted. The company is duly qualified as a foreign corporation to do business and is in good standing in every jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary.

2. The Company has the requisite corporate power and authority to enter into and perform its obligations under the Transaction Documents and to issue the Preferred Stock, the Warrants and the Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants. The execution, delivery and performance of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been duly and validly authorized by all necessary corporate action and no further consent or authorization of the Company or its Board of Directors or stockholders is required. Each of the Transaction Documents have been duly executed and delivered, and the Preferred Stock and the Warrants have been duly executed, issued and delivered by the Company and each of the Transaction Documents constitutes a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its respective terms. The Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants are not subject to any preemptive rights under the Certificate of Incorporation or the Bylaws.

3. The Preferred Stock and the Warrants have been duly authorized and, when delivered against payment in full as provided in the Purchase Agreement, will be validly issued, fully paid and nonassessable. The shares of Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants, have been duly authorized and reserved for issuance, and, when delivered upon conversion or against payment in full as provided in the Certificate of Designation and the Warrants, as applicable, will be validly issued, fully paid and nonassessable.

4. The execution, delivery and performance of and compliance with the terms of the Transaction Documents and the issuance of the Preferred Stock, the Warrants and the Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants do not (i) violate any provision of the Certificate of Incorporation or Bylaws, (ii) to our knowledge conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any material agreement, mortgage, deed of trust, indenture, note, bond, license, lease agreement, instrument or obligation to which the Company is a party, (iii) to our knowledge create or impose a lien, charge or encumbrance on any property of the Company under any agreement or any commitment to which the Company is a party or by which the Company is bound or by which any of its respective properties or assets are bound, or (iv) (a) result in a violation of any federal, state or local statute, rule or regulation, or to our knowledge, any order, judgment, injunction or decree (including Federal and state securities laws and regulations) applicable to the Company or by which any property or asset of the Company is bound or affected, except, in all cases other than violations pursuant to clause (i) above, for such conflicts, default, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect.

-7-

5. No consent, approval or authorization of or designation, declaration or filing with any governmental authority on the part of the Company is required under Federal, state or local law, rule or regulation in connection with the valid execution, delivery and performance of the Transaction Documents, or the offer, sale or issuance of the Preferred Stock, the Warrants or the Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants other than the Certificate of Designation, the Registration Statement, report on Form 8-K and Form D, both to be filed with the Securities and Exchange Commission.

6. To our knowledge, there is no action, suit, claim, investigation or proceeding pending or threatened against the Company which questions the validity of this Agreement or the transactions contemplated hereby or any action taken or to be taken pursuant hereto or thereto. To our knowledge, there is no action, suit, claim, investigation or proceeding pending, or to our knowledge, threatened, against or involving the Company or any of its properties or assets and which, if adversely determined, is reasonably likely to result in a Material Adverse Effect. To our knowledge, there are no outstanding orders, judgments, injunctions, awards or decrees of any court, arbitrator or governmental or regulatory body against the Company or any officers or directors of the Company in their capacities as such.

7. The offer, issuance and sale of the Preferred Stock and the Warrants and the offer, issuance and sale of the shares of Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants pursuant to the Purchase Agreement, the Certificate of Designation and the Warrants, as applicable, are based on the Purchasers’ representations in the Agreement, exempt from the registration requirements of the Securities Act.

8. The Company is not, and as a result of and immediately upon Closing will not be, an “investment company” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.
