No event or circumstance has occurred or information exists with respect to the Company or any of its Subsidiaries or its or their business, properties, prospects, operations or financial conditions, 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, assuming that the press release contemplated by the first sentence of Section 6.6 is issued..

To the knowledge of the Company, other than this Agreement and the related documents, the Company and its Subsidiaries are not a party to any contract or agreement with any Affiliate of the Company or its Subsidiaries, the terms of which are less favorable to the Company or its Subsidiaries than those 16 that might have been obtained, at the time such contract or agreement was entered into, from a Person who was not such an Affiliate. 4.16 Offering of Securities.

The Company acknowledges and agrees that each of the Purchasers is acting solely in the capacity of an arm's length purchaser with respect to this Agreement and the transactions contemplated hereby. The Company further acknowledges that no Purchaser is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated hereby and any advice given by any Purchaser or any of their respective representatives or agents in connection with this Agreement and the transactions contemplated hereby is merely incidental to the Purchasers' 20 purchase of the Securities and Warrant Shares. The Company further represents to each Purchaser that the Company's decision to enter into this Agreement has been based solely on the independent evaluation of the transactions contemplated hereby by the Company and its representatives. The Company did not provide any information to the Purchasers other than the Transaction Documents and the Disclosure Material. SECTION 5. Representations and Warranties of the Purchaser. Each Purchaser, severally but not jointly, represents and warrants to the Company as follows: 5.1 Corporate Power and Authority. The Purchaser has all requisite power, authority and legal right to execute, deliver, enter into, consummate the transactions contemplated by and perform its obligations under this Agreement and the Registration Rights Agreement. The execution, delivery and performance of this Agreement and the Registration Rights Agreement by the Purchaser have been duly authorized by all required corporate and other actions. The Purchaser has duly executed and delivered this Agreement and the Registration Rights Agreement, and this Agreement and the Registration Rights Agreement constitute the legal, valid and binding obligations of the Purchaser enforceable against the Purchaser in accordance with their respective terms, subject to bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to the rights of creditors generally and to general principles of equity. 5.2 Investment Intent. The Purchaser and each account for which it is acting is an Accredited Investor. The Purchaser is capable of evaluating the risk of its investment in the Securities and Warrant Shares being purchased by it and the Purchaser and any account for which the Purchaser is acting is able to bear the economic risk of such investment and the complete loss of such investment. The Purchaser has had the opportunity to request and receive all information deemed necessary by it to evaluate an investment in the Company. The Purchaser confirms that the Company has made available to the Purchaser the opportunity to ask questions of, and receive answers from the Company concerning the terms and conditions of the Securities and the Warrant Shares and the nature of the business of the Company, and to obtain additional information or documents which the Company possesses or can acquire without unreasonable effort or expense. In formulating the decision to acquire the Securities and Warrant Shares, the Purchaser has relied solely upon its own advisors and its own independent investigation of the Company with respect to this Agreement and the nature and effect of any investment in the Securities and Warrant Shares. The Purchaser is purchasing the Securities and Warrant Shares for its own account or for one or more accounts as to each of which it exercises investment discretion solely for the purpose of investment and not with a view to, or for sale in connection with, any distribution thereof in violation of applicable securities laws. The Purchaser acknowledges that the Securities and the Warrant Shares have not been registered under the Securities Act and may be sold or disposed of in the absence of such registration only pursuant to an exemption from the registration requirements of the Securities Act. If the Purchaser should in the future decide to dispose of any of its Securities or Warrant Shares it is understood that it may do so only in 21 compliance with the Securities Act, applicable securities laws and this Agreement. If domiciled in the United States, Purchaser's domicile is in the state indicated on Schedule 1 hereto. Other than the Transaction Documents and the Disclosure Material, the Purchaser did not rely on any other information in determining whether to enter into the Transaction Documents and purchase the Securities. SECTION 6. Transfer; Restrictions and Mechanics 6.1 Transfers. (a) Each Purchaser agrees that it will not sell or otherwise dispose of any Securities or Warrant Shares unless such Securities or Warrant Shares have been registered under the Securities Act and, to the extent required, under any applicable state securities laws, or pursuant to an applicable exemption from such registration requirements, and in each case in compliance with the Securities Act and any applicable state securities laws, including without limitation applicable prospectus delivery requirements. The Company may endorse on all Share and Warrant Share certificates and Warrants a legend stating or referring to such transfer restrictions; provided, that no such legend shall be endorsed on any Share or Warrant Share certificates or Warrants that, when issued, are no longer subject to the restrictions of this Section 6. (b) In connection with any transfer of Securities and Warrant Shares other than pursuant to an effective registration statement or to the Company or pursuant to Rule 144(k), except as otherwise expressly set forth herein, the transferor shall provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration under the Securities Act or applicable state securities laws. Notwithstanding the foregoing, the Company hereby consents to and agrees to register on the books of the Company and with its transfer agent, without any such legal opinion, any transfer of Securities and Warrant Shares by a Purchaser to an Affiliate of such Purchaser, provided that the transferee certifies to the Company that it is an Accredited Investor and delivers to the Company a written statement in which it makes such representations and certification as set forth in Sections 5.2. (c) The Purchaser agrees to the placement on the Warrants and the certificates representing the Shares and Warrant Shares issued to the Purchaser pursuant to the terms hereof, and any Warrant or certificate issued at any time in exchange or substitution for any Warrant or certificate bearing such legend, a legend (the "Private Placement Legend") substantially as set forth below: [NEITHER] THE SECURITIES REPRESENTED BY THIS CERTIFICATE [NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE] HAVE [NOT] BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAW, AND MAY NOT BE OFFERED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE 22 SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NOTWITHSTANDING THE FOREGOING, THESE SECURITIES [AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY SUCH SECURITIES, PROVIDED THAT THE PLEDGEE IS AN "ACCREDITED INVESTOR" WITHIN THE MEANING OF REGULATION D PROMULGATED UNDER THE SECURITIES ACT. (d) Warrants and certificates evidencing Shares or Warrant Shares shall not be required to contain such legend or any other legend (i) while a Registration Statement covering the resale of such Securities or Warrant Shares is effective under the Securities Act, or (ii) following any sale of such Securities or Warrant Shares pursuant to Rule 144, or (iii) if such Securities or Warrant Shares are eligible for sale under Rule 144(k), or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the Staff of the Commission) and the holder shall provide to the Company an opinion of counsel selected by the holder, the form and substance of which opinion shall be reasonably satisfactory to the Company, to such effect; provided, however, that the holder agrees to return any Warrants and certificates evidencing the Shares and Warrant Shares that have not been sold, to the extent practicable, for endorsement of a legend set forth above at such time as the Company notifies the holder that such legend is required because the Registration Statement covering the sale of such Securities or Warrant Shares is no longer effective and none of the other conditions in clauses (ii), (iii) or (iv) has been satisfied. The Company shall cause its counsel to issue the legal opinion included in the Transfer Agent Instructions to the Company's transfer agent on the Effective Date. Following the Effective Date or at such earlier time as a legend is no longer required for certain Securities or Warrant Shares, the Company will no later than five Trading Days following the delivery by a Purchaser and receipt by the Company or the Company's transfer agent of a Warrant or a legended certificate representing Shares or Warrant Shares, deliver or cause to be delivered to such Purchaser a certificate representing such Securities or Warrant Shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section. For so long as any Purchaser owns Securities, the Company will not effect or publicly announce its intention to effect any exchange, recapitalization or other transaction that effectively requires or rewards physical delivery of certificates evidencing the Common Stock, other than as required by applicable law or regulation. (e) The Company acknowledges and agrees that a Purchaser may from time to time pledge or grant a security interest in some or all of the Securities and Warrant Shares in connection with a bona fide margin agreement or other loan or financing arrangement secured by the Securities or Warrant Shares and, if required under the terms of such agreement, loan or arrangement, such Purchaser may transfer pledged or secured Securities or Warrant Shares to the pledgees or secured parties (subject to any restrictions on transfer applicable to such pledgees or secured parties pursuant to applicable law, including without limitation the Securities Act and applicable state securities laws); provided, however, that if such pledge or transfer occurs prior to the Effective Date, the pledgee or transferee must be an Accredited Investor. Such a pledge or transfer 23 would not be subject to approval of the Company and no legal opinion of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser's expense and provision of the selling shareholder and plan of distribution information required to be set forth therein with respect to such pledgee or transferee, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities or Warrant Shares may reasonably request in connection with a pledge or transfer of the Securities or Warrant Shares, including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of selling stockholders in the Prospectus. 6.2 Furnishing of Information. As long as any Purchaser owns Securities or Warrant Shares, 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 the Exchange Act. Upon the request of any Purchaser, the Company shall deliver to such Purchaser a written certification of a duly authorized officer as to whether it has complied with the preceding sentence. As long as any Purchaser owns Securities or Warrant Shares, if the Company is not required to file reports pursuant to such laws, it will prepare and furnish to the Purchasers and make publicly available in accordance with paragraph (c) of Rule 144 such information as is required for the Purchasers to sell the Securities and Warrant Shares under Rule 144. The Company further covenants that it will take such further action as any holder of Securities or Warrant Shares may reasonably request to satisfy the provisions of Rule 144 applicable to the issuer of securities relating to the sale of securities pursuant to Rule 144. 6.3 Integration. The Company shall not, and shall use its reasonable best efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that it knows or should know would be integrated with the offer or sale of the Securities or Warrant Shares in a manner that would require the registration under the Securities Act of the sale of the Securities or Warrant Shares to the Purchasers or that it knows or should know would be integrated with the offer or sale of the Securities or Warrant Shares for purposes of the rules and regulations of any Trading Market. 6.4 Reservation of Securities. The Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents in such amount as may be required to fulfill its obligations in full under the Transaction Documents. In the event that at any time the then authorized shares of Common Stock are insufficient for the Company to satisfy its obligations in full under the Transaction Documents, the Company shall promptly take such actions as may be required to increase the number of authorized shares. 24 6.5 Subsequent Placements. (a) From the date hereof until the Effective Date (the "Blockout Period"), the Company will not, directly or indirectly, offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition of) any of its or the Subsidiaries' equity or equity equivalent securities, including without limitation any debt, preferred stock or other instrument or security that is, at any time during its life and under any circumstances, convertible into or exchangeable or exercisable for Common Stock or Common Stock Equivalents (any such offer, sale, grant, disposition or announcement being referred to as a "Subsequent Placement"). (b) From the end of the Blockout Period until the two year anniversary of the end of the Blockout Period, the Company will not, directly or indirectly, effect any Subsequent Placement unless the Company shall have first complied with this Section 6.5(b). (i) The Company shall deliver to each Principal Purchaser a written notice (the "Offer") of any proposed or intended issuance or sale or exchange of the securities being offered (the "Offered Securities") in a Subsequent Placement, which Offer shall (w) identify and describe the Offered Securities, (x) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (y) identify the persons or entities (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged and (z) offer to issue and sell to or exchange with the Principal Purchasers (A) (1) with respect to the period from the end of the Blockout Period until the one year anniversary of the end of the Blockout Period, a pro rata portion of the Offered Securities, and (2) with respect to the period from the one year anniversary of the end of the Blackout Period until the two year anniversary of the end of the Blockout Period, a pro rata portion of an amount equal to fifty percent (50%) of the Offered Securities, in each case based on such Principal Purchaser's pro rata portion of the aggregate purchase price paid by the Principal Purchasers for all of the Shares purchased by the Principal Purchasers hereunder (the "Basic Amount"), and (b) with respect to each Principal Purchaser that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of other Principal Purchasers as such Principal Purchaser shall indicate it will purchase or acquire should the other Principal Purchasers subscribe for less than their Basic Amounts (the "Undersubscription Amount"). (ii) To accept an Offer, in whole or in part, a Principal Purchaser must deliver a written notice to the Company prior to the end of the five (5) Trading Day period of the Offer (the "Offer Period"), setting forth the portion of the Purchaser's Basic Amount that such Principal Purchaser elects to purchase and, if such Principal Purchaser shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Principal Purchaser elects to purchase (in either case, the "Notice of Acceptance"). If the Basic Amounts subscribed for by all Principal Purchasers are less than the total of all of the Basic Amounts, then each Principal Purchaser who has set forth an Undersubcription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, that if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed for (the "Available 25 Undersubscription Amount"), each Principal Purchaser who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of such Principal Purchaser bears to the total Basic Amounts of all Principal Purchasers that have subscribed for Undersubscription Amounts, subject to rounding by the Board of Directors to the extent its deems reasonably necessary. If requested by the Company, a Principal Purchaser shall promptly confirm in writing any decision not to purchase Offered Securities. (iii) The Company shall have ten (10) Trading Days from the expiration of the Offer Period above to offer, issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Principal Purchasers (the "Refused Securities"), but only to the offerees described in the Offer (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring person or persons or less favorable to the Company than those set forth in the Offer. (iv) In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 6.5(b)(iii) above), then each Principal Purchaser may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that the Principal Purchaser elected to purchase pursuant to Section 6.5(b)(ii) above multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Principal Purchasers pursuant to Section 6.5(b)(ii) above prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Principal Purchaser so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Principal Purchasers in accordance with Section 6.5(b)(i) above. (v) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, the Principal Purchasers shall acquire from the Company, and the Company shall issue to the Principal Purchasers, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 6.5(b)(iv) above if the Principal Purchasers have so elected, upon the terms and conditions specified in the Offer. The purchase by the Principal Purchasers of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Principal Purchasers of a purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Principal Purchasers and their respective counsel. (vi) Any Offered Securities not acquired by the Principal Purchasers or other persons in accordance with Section 6.5(b)(iii) above may not be issued, sold or exchanged until they are again offered to the Principal Purchasers under the procedures specified in this Agreement. 26 (vii) Anything in this Section 6.5 to the contrary notwithstanding, the rights of the Principal Purchasers in this Section 6.5 are subordinate and subject to the preemptive rights of the holders of the Series 2 Preferred Stock to purchase up to five percent of any offering of Common Stock or Common Stock Equivalents. (c) The restrictions contained in paragraphs (a) and (b) of this Section 6.5 shall not apply to the issuance of Excluded Stock. 6.6 Securities Laws Disclosure; Publicity. The Company shall, on or before 9:30 a.m., Eastern Standard Time, on the Closing Date, issue a press release reasonably acceptable to the Purchasers disclosing all material terms of the transactions contemplated hereby. Within one Trading Day after the Closing Date, the Company shall file a Current Report on Form 8-K with the Commission (the "8-K Filing") describing the terms of the transactions contemplated by the Transaction Documents and including as exhibits to such Current Report on Form 8-K this Agreement and the form of Warrants, in the form required by the Exchange Act. Thereafter, the Company shall timely file any filings and notices required by the Commission or applicable law with respect to the transactions contemplated hereby and provide copies thereof to the Special Counsel promptly after filing. The Company shall, at least two Trading Days prior to the filing or dissemination of any disclosure required by this paragraph, provide a copy thereof to the Special Counsel for its review, except that with respect to the press release and 8-K Filing, such period can be less to the extent necessary to make such filings timely pursuant to this Section 6.6. The Company and the Purchasers, through its Special Counsel, shall consult with each other in issuing any press releases or otherwise making public statements or filings and other communications with the Commission or any regulatory agency or Trading Market with respect to the transactions contemplated hereby, and no party shall issue any such press release or otherwise make any such public statement, filing or other communication without the prior consent of the other, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement, filing or other communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (a) to the extent that such disclosure is consistent with disclosure that has previously been authorized under this Section or (b) to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Special Counsel with prior notice of such disclosure. The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers, directors, employees and agents not to, provide any Purchaser with any material nonpublic information regarding the Company or any of its Subsidiaries from and after the filing of the 8-K Filing without the express written consent of such Purchaser, other than as may be necessary to satisfy the Company's obligation under Section 6.5. In the event of a breach of the foregoing covenant, or the failure to disclose any material non-public information provided pursuant to Section 6.5 on the related closing date, by the Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided herein or in the Transaction Documents, a Purchaser shall have the right to require the Company to make a public disclosure of such information and, if the Company has not publicly disclosed such information by the later of (i) 24 hours after such 27 request and (ii) 5:30 p.m. (New York City time) on the next Trading Day after such request, the requesting Purchaser may disclose such information in the form of a press release, public advertisement or otherwise, of such material nonpublic information without the prior approval by the Company, its Subsidiaries, or any of its or their respective officers, directors, employees or agents. No Purchaser shall have any liability to the Company, its Subsidiaries, or any of its or their respective officers, directors, employees, shareholders or agents for any such disclosure. Subject to the foregoing, the Company and the Purchasers shall not issue any press releases or any other public statements with respect to the transactions contemplated hereby; provided, however, that the Company shall be entitled, without the prior approval of any Purchaser, to make any press release or other public disclosure with respect to such transactions (i) in substantial conformity with the 8-K Filing and (ii) as is required by applicable law and regulations. Each press release disseminated during the three years preceding the date of this Agreement did not at the time of release contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading. 6.7 Additional Issuance of Shares (a) In the event that after the date hereof and prior to the first anniversary of the date hereof the Company issues or agrees to issue any Common Stock or Common Stock Equivalents, other than Excluded Stock, for a consideration (net of any discounts, fees, and commissions) to the Company per share less than the Reference Price (the "Issuance Price"), each Purchaser shall be entitled to receive such number of additional shares of Common Stock (upon payment to the Company of an amount per share equal to the par value of such additional shares of Common Stock), equal to the excess of (A) the quotient obtained by dividing the aggregate purchase price plus exercise price paid by such Purchaser for such Purchaser's Eligible Shares (it being assumed for this purpose that no portion of the purchase price is attributable to the Warrants) divided by the Issuance Price over (B) the number of Eligible Shares then held by such Purchaser. (b) For purposes of any issuances of additional shares of Common Stock to a Purchaser under Section 6.7(a) above, the following provisions shall be applicable: (i) In connection with any issuance of any Common Stock Equivalents, (x) the maximum number of shares of Common Stock potentially issuable at any time upon conversion, exercise or exchange of such Common Stock Equivalents (the "Deemed Number") shall be deemed to be outstanding upon issuance of such Common Stock Equivalents, and (y) the amount of the consideration received by the Company with respect to such Common Stock Equivalents shall be deemed to equal the aggregate minimum dollar value of consideration payable to the Company to purchase such Common Stock Equivalents and to convert, exercise or exchange them into Common Stock (the "Deemed Consideration"). With respect to the issuance of any Common Stock Equivalents, the Issuance Price shall be calculated by dividing the Deemed Consideration by the Deemed Number. With respect to the issuance of any Common Stock Equivalents and Common Stock, the Issuance Price shall be calculated by dividing (A) the sum of (I) the amount of consideration received by the Company for the Common Stock and (II) the Deemed 28 Consideration by (B) the sum of (I) the number of shares of Common Stock sold in such transaction and (II) the Deemed Number. No further adjustment shall be made under this Section upon the actual issuance of Common Stock upon conversion, exercise or exchange of such Common Stock Equivalents. (ii) In the case of the issuance of Common Stock or Common Stock Equivalents for a consideration in whole or in part other than cash, including securities acquired in exchange therefor (other than securities by their terms so exchangeable), the consideration other than cash shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors of the Company, irrespective of any accounting treatment. (c) For purposes of this Section 6.7, the following definitions shall apply: "Eligible Shares" shall mean, for each Purchaser, at the time of an issuance of additional shares of Common Stock or Convertible Securities, the sum of (x) the lesser of (A) the number of shares of Common Stock then held by such Purchaser and its Affiliates (other than shares of Common Stock (i) acquired by such Purchaser upon exercise of a Warrant or (ii) issued to such Purchaser pursuant to this Section 6.7 or (iii) purchased by such Purchaser on the open market or otherwise (other than purchases which can be matched against any sale occurring within three Trading Days thereof)) and (B) the number of Shares purchased by such Purchaser hereunder and (y) the number of shares of Common Stock acquired by such Purchaser upon exercise of a Warrant or issued to such Purchaser pursuant to this Section 6.7. Upon request of the Company, each Purchaser shall provide the Company with a written certification of the number of Eligible Shares then held by such Purchaser and such supporting information as the Company may reasonable request. "Reference Price" shall initially be $5.462 and, at any time after additional shares of Common Stock are issued to a Purchaser pursuant to this Section 6.7, shall be equal to the lowest Issuance Price. (d) Notwithstanding anything to the contrary contained in this Section 6.7, the number of shares of Common Stock that shall be issued to a Purchaser pursuant hereto shall be limited to the extent necessary to insure that, following such issuance, the total number of shares of Common Stock then beneficially owned by such Purchaser and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Purchaser's for purposes of Sections 13(d) of the Exchange Act, does not exceed 4.999% (the "Maximum Percentage") of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon exercise of all Warrants and other Convertible Securities held by such Purchaser and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be so aggregated). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. The Company's obligation to issue shares in excess of the foregoing limitation shall be suspended until such time, if any, as such shares of Common Stock may be issued in compliance with such limitation. Additionally, by written notice to the Company, the Purchaser may waive the provisions of this Section or increase or 29 decrease (but not below 4.999%) the Maximum Percentage to any other percentage specified in such notice, but (i) any such waiver or increase will not be effective until the 61st day after such notice is delivered to the Company, and (ii) any such waiver or increase or decrease will apply only to the Purchaser and not to any other Purchaser. (e) All shares to be issued pursuant to this Section 6.7, upon issuance, shall be validly issued, fully-paid and non-assessable and free of any Liens or preemptive or similar rights. Upon the issuance of any shares of Common Stock pursuant to this Section 6.7, such shares shall be "Shares" and "Registrable Securities" for all purposes hereunder. Without limiting the generality of the foregoing, the Purchasers shall have all of the rights provided in the Registration Rights Agreement with respect to such additional Shares, mutatis mutandis. 6.8 Trading Market Limitations. (a) Notwithstanding any provisions of Section 6.7, to the contrary, if the Trading Market is the Nasdaq National Market or the Nasdaq SmallCap Market or any other market or exchange with similar applicable rules, then the maximum number of shares of Common Stock that the Company may issue pursuant to the Transaction Documents at an effective purchase price less than the Closing Price on the Trading Day immediately preceding the Closing Date is 9,572,408 shares of Common Stock (the "Issuable Maximum"), unless the Company obtains shareholder approval in accordance with the rules and regulations of such Trading Market (the "Shareholder Approval Requirement"). If at the time any Purchaser requests an exercise of any Securities or additional shares of Common Stock become issuable pursuant to Section 6.7 hereof or under any Transaction Document, the Actual Minimum (excluding any shares issued or issuable at an effective purchase price in excess of the Closing Price on the Trading Day immediately preceding the Closing Date) exceeds the Issuable Maximum (and if the Company has not previously obtained the required shareholder approval), then the Company shall issue to the Purchaser requesting such exercise or entitled to such additional shares a number of shares of Common Stock not exceeding such Purchaser's pro-rata portion of the Issuable Maximum (based on such Purchaser's share (vis-a-vis other Purchasers) of the aggregate purchase price paid hereunder and taking into account any Warrant Shares previously issued to such Purchaser), and the remainder of the Warrant Shares issuable in connection with such exercise or additional shares of Common Stock issuable pursuant to Section 6.7 shall constitute "Excess Shares" pursuant to Section 6.8(b) below. (b) In the event that any Purchaser's receipt of shares of Common Stock upon exercise of Securities or pursuant to Section 6.7 is restricted based on the Issuable Maximum, the Company shall either: (i) use its reasonable best efforts to obtain the required shareholder approval necessary to permit the issuance of such Excess Shares as soon as is reasonably possible, but in any event not later than the 90th day after the event giving rise to such Excess Shares, or (ii) within five Trading Days after such event, pay cash to such Purchaser, as liquidated damages and not as a penalty, in an amount equal to the number of Excess Shares multiplied by the average Closing Price over the five Trading Days immediately prior to the date of such event or, if greater, the five Trading Days immediately prior to the date of payment (the "Cash Amount"). If the Company elects the first option under the preceding sentence and the Company fails to obtain the required shareholder approval on or prior to the 90th day after such event, then within three Trading Days after such 90th day, the Company shall pay the Cash Amount to such Purchaser, as liquidated damages 30 and not as penalty; provided, however, that the Company shall not be required to pay the Cash Amount to the extent such payment would violate the Shareholder Approval Requirement or subject the Company to delisting under the rules and interpretations of the Trading Market on which the Company's Common Stock is listed and thereafter the Company shall have no obligation with respect to such Excess Shares. SECTION 7. Negative Covenants. 7.1 Private Placement Status. Neither the Company nor any agent or other Person acting on the Company's behalf will do or cause to be done (or will omit to do or to cause to be done) any act, which act (or which omission) would result in bringing the issuance or sale of the Securities and Warrant Shares within the provisions of Section 5 of the Securities Act or the filing, notification or reporting requirements of any state securities law. 7.2 Actions Prior to the Closing Date. From the date hereof through the Closing Date, the Company will not, (a) issue or agree to issue any capital stock or any securities exercisable for, or convertible or exchangeable into, capital stock or (b) purchase, redeem or otherwise acquire any of its capital stock; provided, however, that this Section 7.2 shall not limit, or be applicable to, (i) the transactions contemplated by this Agreement, (ii) grants of options or issuances of Common Stock to officers, directors or employees of the Company pursuant to the current terms of the Company's 1995 Stock Incentive Plan, the Company's 1999 Equity Incentive Plan and the 2001 Employee Stock Purchase Plan and (iii) the conversion of the Series 2 Preferred Stock or the exercise of existing warrants or options.

The purchase of and payment for the Securities shall not be prohibited by any law or governmental order, rule, ruling, regulation, release, interpretation or opinion applicable to the Purchaser and shall not subject the Purchaser to any penalty, tax, liability or other onerous condition. No legal action, suit or proceeding shall be pending or threatened which seeks to restrain or prohibit the transactions contemplated by this Agreement.

All statements contained in any certificate or other closing document delivered by or on behalf of the Company pursuant hereto shall constitute representations and warranties by the Company hereunder. (b) If any Purchaser or any of its Affiliates or any officer, director, partner, controlling person, employee or agent of a Purchaser or any of its Affiliates (a "Related Person") becomes involved in any capacity in any Proceeding brought by any Person (other than the Purchasers and their Related 33 Persons) directly in connection with or as a result of the transactions contemplated by the Transaction Documents (other than relating to the Registration Statement, prospectus or other matter covered by the indemnity in Section 2.7 of the Registration Rights Agreement), the Company will indemnify and hold harmless such Purchaser or Related Person for its reasonable legal and other expenses (including the reasonable costs of any investigation, preparation and travel) and for any Losses incurred in connection therewith, if and as such expenses or Losses are actually incurred, excluding only Losses that arise out of or result directly from such Purchaser's or Related Person's gross negligence or willful misconduct. In addition, the Company shall indemnify and hold harmless each Purchaser and Related Person from and against any and all Losses, if and as actually incurred, arising out of or relating to any breach by the Company of any of the representations, warranties or covenants made by the Company in this Agreement or any other Transaction Document.

The Company also agrees that neither the Purchasers nor any Related Persons shall have any liability to the Company or any Person asserting claims on behalf of or in right of the Company in connection with or as a result of the transactions contemplated by the Transaction Documents, except to the extent that any Losses incurred by the Company arise out of or result directly from the gross negligence or willful misconduct of the applicable Purchaser or Related Person in connection with such transactions or arise out of or relate to any breach by a Purchaser of any of the representations, warranties or covenants made by a Purchaser in this Agreement or any other Transaction Document. If the Company breaches its obligations under any Transaction Document, then, in addition to any other liabilities the Company may have under any Transaction Document or applicable law, the Company shall pay or reimburse the Purchasers on demand for all costs of collection and enforcement (including reasonable attorneys fees and expenses) actually incurred and reasonably documented.

SECTION 11. Specific Performance The parties agree that irreparable damage will result in the event that this Agreement is not specifically enforced, and the parties agree that any damages available at law for a breach of this Agreement would not be an adequate remedy. Therefore, the provisions hereof and the obligations of the parties hereunder shall be enforceable in a court of equity, or other tribunal with jurisdiction, by a decree of specific performance, and appropriate injunctive relief may be applied for and granted in connection therewith. Such remedies and all other remedies provided for in this Agreement shall, however, be cumulative and not exclusive and shall be in addition to any other remedies that a party may have under this Agreement or otherwise. SECTION 12.

(b) Promptly after obtaining the written consent of the holders as herein provided, the Company shall transmit a copy of any amendment, waiver, modification or termination that has been adopted to all holders of Securities and Warrant Shares then outstanding, but failure to transmit copies shall not in any way affect the validity of any such amendment, waiver, modification or termination.

Kansler, Esq. 36 SECTION 15. Miscellaneous (a) The Transaction Documents and, upon any closing hereunder together with any further agreements entered into by the Purchasers and the Company at any closing hereunder, contain the entire agreement between the Purchasers and the Company, and supersede any prior oral or written agreements, commitments, terms or understandings, regarding the subject matter hereof, including without limitation any term sheet. (b) Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereby waive any provision of law that may render any provision hereof prohibited or unenforceable in any respect. (c) This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, whether so expressed or not; provided, that (a) the Company may not assign any of its rights, duties or obligations under this Agreement, except with the Purchasers' written consent, which may be withheld for any reason, and (b) a Purchaser may assign any of its rights, duties or obligations under this Agreement to any transferee of its Securities or Warrant Shares and (unless such assignment expressly provides otherwise) any such assignment shall not diminish the rights such Purchaser would otherwise have under this Agreement or with respect to any remaining Securities or Warrant Shares held by such Purchaser. In the event that any Securities or Warrant Shares are transferred either (a) in a public offering pursuant to a Registration Statement under Section 5 of the Securities Act, (b) pursuant to a Rule 144 Transaction, or (c) pursuant to another transaction exempt from the registration and prospectus delivery requirements of the Securities Act under Section 4(1) thereof so that all transfer restrictions and restrictive legends with respect to such Securities or Warrant Shares, if any, are removed upon the consummation of such sale or transfer, then the transferees of such Securities or Warrant Shares, as the case may be, shall not be entitled to any benefits under this Agreement or the Registration Rights Agreement with respect to such Securities or Warrant Shares and such Securities or Warrant Shares shall no longer be considered to be "Outstanding" for purposes of any consent or waiver provision of this Agreement or the Registration Rights Agreement. (d) No course of dealing and no delay on the part of any party hereto in exercising any right, power, or remedy conferred by this Agreement shall operate as a waiver thereof or otherwise prejudice such party's rights, powers and remedies. No single or partial exercise of any right, power or remedy conferred by this Agreement shall preclude any other or further exercise thereof or the exercise of any other right, power or remedy. (e) The headings and captions in this Agreement are for convenience of reference only and shall not define, limit or otherwise affect any of the terms or provisions hereof. 37 (f) This Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reasons of this Agreement. (g) This Agreement may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument, and all signatures need not appear on any one counterpart. (h) This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except that each Related Person is an intended third party beneficiary of Section 9(b) and may enforce the provision of such Section directly against the parties with obligations thereunder. (i) ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY, ENFORCEMENT AND INTERPRETATION OF THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (OTHER THAN ANY CONFLICT OF LAW RULES THAT MIGHT RESULT IN THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION). THE COMPANY AND PURCHASERS HEREBY IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING IN THE CITY OF NEW YORK, BOROUGH OF MANHATTAN FOR THE ADJUDICATION OF ANY DISPUTE BROUGHT BY THE COMPANY OR ANY PURCHASER HEREUNDER, IN CONNECTION HEREWITH OR WITH ANY TRANSACTION CONTEMPLATED HEREBY OR DISCUSSED HEREIN (INCLUDING WITH RESPECT TO THE ENFORCEMENT OF ANY OF THE TRANSACTION DOCUMENTS), AND HEREBY IRREVOCABLY WAIVE, AND AGREE NOT TO ASSERT IN ANY SUIT, ACTION OR PROCEEDING BROUGHT BY THE COMPANY OR ANY PURCHASER, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF ANY SUCH COURT, OR THAT SUCH SUIT, ACTION OR PROCEEDING IS IMPROPER. EACH PARTY HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT, ACTION OR PROCEEDING BY MAILING A COPY THEREOF VIA REGISTERED OR CERTIFIED MAIL OR OVERNIGHT DELIVERY (WITH EVIDENCE OF DELIVERY) 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 CONTAINED HEREIN SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT TO SERVE PROCESS IN ANY MANNER PERMITTED BY LAW. THE COMPANY AND PURCHASERS HEREBY WAIVE ALL RIGHTS TO A TRIAL BY JURY. (j) If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement. 38 (k) Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights. (l) If any certificate or instrument evidencing any Securities or Warrant Shares is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities or Warrant Shares. (m) To the extent that the Company makes a payment or payments to any Purchaser hereunder or pursuant to the Warrants or any Purchaser enforces or exercises its rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company by a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred. (n) In the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof, each reference in any Transaction Document to a number of shares or a price per share shall be amended to appropriately account for such event. (o) The obligations of each Purchaser under any Transaction Document 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 any Transaction Document. The decision of each Purchaser to purchase Shares pursuant to this Agreement has been made by such Purchaser independently of any other Purchaser 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 the Subsidiary which may have been made or given by any other Purchaser or by any agent or employee 39 of any other Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any other Purchaser (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant 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 Document. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no other Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment hereunder. 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.
