The Company agrees to purchase from the Investors, for an aggregate purchase price of $3,500,000 (the “Purchase Price”), all of the Series A Warrants and Series B Warrants owned by Investors (the “Warrant Purchase”). The Purchase Price shall be paid to the Investors in proportion to their ownership of the Series A Warrants and Series B Warrants together, and upon payment of the Purchase Price, the Series A Warrants and Series B Warrants shall be cancelled and of no further force or effect. The Purchase Price shall be paid at the closing of the New Financing. Upon receipt of payment of the Purchase Price, Investors agree to return the Series A Warrants and Series B Warrants to the Company.

(b) Company Purchase of D Warrants. The Company agrees to purchase from the Investors, simultaneous with the Warrant Purchase, for a purchase price equal to 770,897 shares of Series B Preferred Stock (or one (1) newly issued share of Series B Convertible Preferred Stock for every two (2) shares of Common Stock issuable upon the exercise of all Series D Warrants) (the “Preferred Stock Purchase Price”), all of the Series D Warrants owned by Investors. The Preferred Stock Purchase Price shall be paid to the Investors in proportion to their ownership of the Series D Warrants together upon presentation of the original Series D Warrants.

(b) Notwithstanding anything to the contrary set forth in this Section 2, in the event the Commission does not permit the Company to register all of the Registrable Securities in the Registration Statement because of the Commission’s application of Rule 415 or the Commission requires the Company to either exclude shares held by certain Holders or deem such Holders to be underwriters with respect to their Registrable Securities, the Company shall register in the Registration Statement such number of Registrable Securities as is permitted by the Commission without naming such Holder as an underwriter (unless such Holder agrees to be named as an underwriter), provided, however, that the number of Registrable Securities to be included in such Registration Statement or any subsequent registration statement shall be determined in the following order: (i) first, 136,120 shares of Common Stock acquired by Vision from the Company’s prior “shell company” holders, (ii) second, 321,168 shares of Common Stock issued to Vision as “make good shares” for 2006 under the Stock Purchase Agreements, (iii) third, 1,094,891 shares of Common Stock issued upon the exercise of certain warrants held by Vision, (iv) fourth, the shares of Common Stock issuable upon conversion of the Preferred Stock (including, without limitation, 2,919,708 shares issuable upon the conversion of shares of Preferred Stock held by Vision and 770,897 shares of Common Stock issuable upon conversion of the new shares of Preferred Stock issued to Vision pursuant to Section 1.1(b) of the Amendment Agreement) shall be registered on a pro rata basis among the holders of the Preferred Stock, (v) fifth, the shares of Common Stock issuable upon exercise of the New Warrants, and (vi) sixth, the shares of Common Stock issuable upon exercise of any other outstanding Warrants (including, without limitation, 2,657,807 shares of Common stock issuable upon the exercise of the Series C Warrant held by Vision) shall be registered on a pro rata basis among the holders of the Warrants. In the event the Commission does not permit the Company to register all of the Registrable Securities in the initial Registration Statement, the Company shall use its commercially reasonable efforts to file subsequent Registration Statements to register the Registrable Securities that were not registered in the initial Registration Statement as promptly as possible and in a manner permitted by the Commission. For purposes of this Section 2(b), “Filing Date” means with respect to each subsequent Registration Statement filed pursuant hereto, the later of (i) sixty (60) days following the sale of substantially all of the Registrable Securities included in the initial Registration Statement or any subsequent Registration Statement and (ii) six (6) months following the effective date of the initial Registration Statement or any subsequent Registration Statement, as applicable, or such earlier or later date as permitted or required by the Commission. 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 is reviewed 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 promptly 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 herewith and the Securities Act and the rules promulgated thereunder) in accordance with the plan of distribution as set forth on Exhibit A hereto and in accordance with applicable law, 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 and any 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 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 Special Counsel, to conduct a reasonable review of such documents. The Company shall not file the Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable Securities or any Special Counsel shall reasonably object in writing within three (3) Business Days of their receipt thereof.

(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 as necessary 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, but in no event later than ten (10) Business Days, to any comments received from the Commission with respect to the Registration Statement or any amendment thereto and to provide the Holders, within such ten (10) Business Day period, true and complete copies of all correspondence from and to the Commission relating to the Registration Statement; (iv) file the final prospectus pursuant to Rule 424 of the Securities Act no later than 1:00 p.m. Eastern Time on the Business Day following the date the Registration Statement is declared effective by the Commission; and (v) 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 Effectiveness 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 of Registrable Securities and any Special Counsel as promptly as possible (and, in the case of (i)(A) below, not less than three (3) Business Days prior to such filing, and in the case of (iii) below, on the same day of receipt by the Company of such notice from the Commission) 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 or threatening 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 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, as promptly as possible, (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.

(e) If requested by the Holders of a majority in interest of the Registrable Securities, (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) If requested by any Holder, furnish to such Holder and any Special Counsel, 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 each Holder and any Special Counsel, 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 subject to the provisions of Sections 3(m) and 3(n), 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 any 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, to the extent permitted by the Transaction Documents and applicable federal and state securities laws, shall be free of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any Holder may request in connection with 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 the Registration Statement to be listed on the OTC Bulletin Board or any other securities exchange, quotation system or market, if any, on which similar securities issued by the Company are then listed or traded as and when required pursuant to the Transaction Documents.

(l) Comply in all material respects with all applicable rules and regulations of the Commission and make generally available to its security holders all documents filed or required to be filed with the Commission, including, but not limited, to, 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 12-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, Prospectus, or any amendment or supplement thereto, 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 it will not sell any Registrable Securities under the Registration Statement until the Company has electronically filed the Prospectus as then amended or supplemented as contemplated in Section 3(g) and notice from the Company that the Registration Statement and any post-effective amendments thereto have become effective as contemplated by Section 3(c).

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)(iv), 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 (the "Advice") 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) At any time following the date that the Registration Statement is declared effective by the Commission, if (i) there is material non-public information regarding the Company which the Company's Board of Directors (the "Board") determines not to be in the Company's best interest to disclose and which the Company is not otherwise required to disclose, (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 determines not to be in the Company's best interest to disclose, or (iii) the Company is required to file a post-effective amendment to the Registration Statement to incorporate the Company’s quarterly and annual reports and audited financial statements on Forms 10-QSB and 10-KSB, then the Company may postpone or suspend effectiveness of a registration statement for a period not to exceed twenty (20) consecutive days; provided that the Company may not suspend effectiveness of a registration statement under this Section 3(n) for more than forty-five (45) days in the aggregate during any three hundred sixty (360) day period; provided, however, that no such suspension shall be permitted for consecutive twenty (20) day periods arising out of the same set of facts, circumstances or transactions.

4. Registration Expenses.

All fees and expenses incident to the performance of or compliance with this Agreement by the Company, except as and to the extent specified in this Section 4, shall be borne by the Company whether or not the Registration Statement is filed or becomes effective and whether or not any Registrable Securities are sold pursuant to the Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with the OTC Bulletin Board and each other securities exchange or market on which Registrable Securities are required hereunder to be listed, if any, (B) with respect to filing fees required to be paid to the National Association of Securities Dealers, Inc. and the NASD Regulation, Inc. and (C) in compliance with state securities or Blue Sky laws (including, without limitation, fees and disbursements of counsel for the Holders in connection with Blue Sky qualifications of the Registrable Securities and determination of the eligibility of the Registrable Securities for investment under the laws of such jurisdictions as the Holders of a majority of Registrable Securities may designate)), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities and of printing prospectuses if the printing of prospectuses is requested by the holders of a majority of the Registrable Securities included in the Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company and Special Counsel for the Holders, in the case of the Special Counsel, up to a maximum amount of $7,500, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by this Agreement, including, without limitation, the Company's independent public accountants (including the expenses of any comfort letters or costs associated with the delivery by independent public accountants of a comfort letter or comfort letters). In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange as required hereunder.

5. Indemnification.

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors, managers, partners, members, shareholders, agents, brokers, investment advisors and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, costs of preparation and attorneys' fees) and expenses (collectively, "Losses"), as incurred, arising out of or relating to any violation of securities laws or untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated 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, except to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding such Holder or such other Indemnified Party furnished in writing to the Company by such Holder expressly for use therein. 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, its 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 and 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 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 or other Indemnifying Party to the Company specifically for inclusion in the Registration Statement or such Prospectus. Notwithstanding anything to the contrary contained herein, each Holder shall be liable under this Section 5(b) for only that amount as does not exceed the net proceeds to such Holder as a result of the sale of Registrable Securities pursuant to such Registration Statement.

(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 be entitled to 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 parties shall have been advised by counsel 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 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 pending or threatened Proceeding in respect of which any Indemnified Party is a party and indemnity has been sought hereunder, 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 Indemnified Party shall 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 due but 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 benefits received by the Indemnifying Party on the one hand and the Indemnified Party on the other from the offering of the Preferred Stock and the Warrants. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault, as applicable, 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 pursuant to the law.

6. Rule 144.

As long as any Holder owns Preferred Stock, Warrants or 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. As long as any Holder owns Preferred Stock, Warrants or 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 Holders 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 Conversion Shares and Warrant Shares 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, such 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. Except as contemplated by the New Financing or as disclosed in the Transaction Documents, 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 in connection with the New Financing or as disclosed in the Transaction Documents or on Schedule II hereto, 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 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 on 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 right so granted is subject in all respects to the prior rights in full of the Holders set forth herein, and is not otherwise in conflict with the provisions of this Agreement.

(d) Piggy-Back Registrations. Except in connection with the registration statement to be filed in connection with the New Financing, if at any time when there is not an effective Registration Statement providing for the resale of 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 of Registrable Securities written notice of such determination and, if within thirty (30) days after receipt of such notice, or within such shorter period of time as may be specified by the Company in such written notice as may be necessary for the Company to comply with its obligations with respect to the timing of the filing of such registration statement, any such holder shall so request in writing (which request shall specify the Registrable Securities intended to be disposed of by the Purchasers), 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 (x) the number of Registrable Securities of the Holders included in 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), if the Company after consultation with the underwriter(s) recommends the inclusion of fewer Registrable Securities, or (y) none of the Registrable Securities of the Holders shall be included in such registration statement, if the Company after consultation with the underwriter(s) recommends the inclusion of none of such Registrable Securities; provided, however, that if securities are being offered for the account of other persons or entities as well as the Company, 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 (other than the Company).

(e) Failure to File Registration Statement and Other Events. The Company and the Purchasers 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) the Registration Statement is not filed on or prior to the Filing Date, or (B) the Registration Statement is not declared effective by the Commission on or prior to the Effectiveness Date (or in the event an additional Registration Statement is filed because the actual number of shares of Common Stock into which the Warrants are exercisable exceeds the number of shares of Common Stock initially registered is not filed and declared effective with the time periods set forth in Section 2), or (C) 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 (D) the Registration Statement is filed with and declared effective by the Commission but thereafter ceases to be effective as to all Registrable Securities at any time prior to the expiration of the Effectiveness Period, without being succeeded promptly by a subsequent Registration Statement filed with and declared effective by the Commission in accordance with Section 2 hereof, or (E) the Company has breached Section 3(n), or (F) trading in the Common Stock shall be suspended or if the Common Stock is delisted from or no longer quoted on the OTC Bulletin Board (or other principal exchange on which the Common Stock is listed or traded) for any reason for more than three (3) Business Days in the aggregate (any such failure or breach being referred to as an "Event," and for purposes of clauses (A) and (B) the date on which such Event occurs, or for purposes of clause (C) the date on which such three (3) Business Day period is exceeded, or for purposes of clause (D) after more than fifteen (15) Business Days, or for purposes of clause (F) the date on which such three (3) Business Day period is exceeded, being referred to as "Event Date"), the Company shall pay an amount in cash as liquidated damages to each Holder equal to two percent (2%) for each calendar month (prorated for shorter periods) of the Holder’s initial investment in the Preferred Stock from the Event Date until the applicable Event is cured; 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 percent (20%) of the amount of the Holder’s initial investment in the Preferred Stock. The Company shall not be liable for liquidated damages under this Agreement as to any Registrable Securities which are not permitted by the Commission to be included in a Registration Statement because of its application of Rule 415 until such time as the provisions of this Agreement as to the Registration Statements required to be filed pursuant to Section 2(b) are triggered, in which case the provisions of this Section 7(e) shall once again apply, if applicable. In such case, the liquidated damages shall be calculated to only apply to the percentage of Registrable Securities which are permitted by the Commission to be included in the Registration Statement. Notwithstanding anything to the contrary in this paragraph (e), if (i) any of the Events described in clauses (A), (B), (C), (D) or (F) shall have occurred, (II) on or prior to the applicable Event Date, the Company shall have exercised its rights under Section 3(n) hereof and (III) 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.

(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 Holders of a majority of the Registrable Securities outstanding.

(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 overnight delivery by nationally recognized overnight courier service or (iv) actual receipt by the party to whom such notice is required to be given.

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.

Exhibit A

Plan of Distribution

The selling security holders and any of their pledgees, donees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of common stock being offered under this prospectus on any stock exchange, market or trading facility on which shares of our common stock are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling security holders may use any one or more of the following methods when disposing of shares:

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

purchases by a broker-dealer as principal and resales by the broker-dealer for its account;

an exchange distribution in accordance with the rules of the applicable exchange;

privately negotiated transactions;

to cover short sales made after the date that the registration statement of which this prospectus is a part is declared effective by the Commission;

broker-dealers may agree with the selling security holders to sell a specified number of such shares at a stipulated price per share;

a combination of any of these methods of sale; and

any other method permitted pursuant to applicable law.

The shares may also be sold under Rule 144 under the Securities Act of 1933, as amended (“Securities Act”), if available, rather than under this prospectus. The selling security holders have the sole and absolute discretion not to accept any purchase offer or make any sale of shares if they deem the purchase price to be unsatisfactory at any particular time.

The selling security holders may pledge their shares to their brokers under the margin provisions of customer agreements. If a selling security holder defaults on a margin loan, the broker may, from time to time, offer and sell the pledged shares.

Broker-dealers engaged by the selling security holders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, which commissions as to a particular broker or dealer may be in excess of customary commissions to the extent permitted by applicable law.

If sales of shares offered under this prospectus are made to broker-dealers as principals, we would be required to file a post-effective amendment to the registration statement of which this prospectus is a part. In the post-effective amendment, we would be required to disclose the names of any participating broker-dealers and the compensation arrangements relating to such sales.

The selling security holders and any broker-dealers or agents that are involved in selling the shares offered under this prospectus may be deemed to be “underwriters” within the meaning of the Securities Act in connection with these sales. Commissions received by these broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Any broker-dealers or agents that are deemed to be underwriters may not sell shares offered under this prospectus unless and until we set forth the names of the underwriters and the material details of their underwriting arrangements in a supplement to this prospectus or, if required, in a replacement prospectus included in a post-effective amendment to the registration statement of which this prospectus is a part.

The selling security holders and any other persons participating in the sale or distribution of the shares offered under this prospectus will be subject to applicable provisions of the Exchange Act, and the rules and regulations under that act, including Regulation M. These provisions may restrict activities of, and limit the timing of purchases and sales of any of the shares by, the selling security holders or any other person. Furthermore, under Regulation M, persons engaged in a distribution of securities are prohibited from simultaneously engaging in market making and other activities with respect to those securities for a specified period of time prior to the commencement of such distributions, subject to specified exceptions or exemptions. All of these limitations may affect the marketability of the shares.

If any of the shares of common stock offered for sale pursuant to this prospectus are transferred other than pursuant to a sale under this prospectus, then subsequent holders could not use this prospectus until a post-effective amendment or prospectus supplement is filed, naming such holders. We offer no assurance as to whether any of the selling security holders will sell all or any portion of the shares offered under this prospectus.

We have agreed to pay all fees and expenses we incur incident to the registration of the shares being offered under this prospectus. However, each selling security holder and purchaser is responsible for paying any discounts, commissions and similar selling expenses they incur.

We and the selling security holders have agreed to indemnify one another against certain losses, damages and liabilities arising in connection with this prospectus, including liabilities under the Securities Act.
