The Registration Statement shall be on Form S-1 (or another appropriate form in accordance herewith).

The Company shall request that the effective time of the Registration Statement be 4:00 p.m. Eastern Time on the Effectiveness Date. If at any time and for any reason, an additional Registration Statement is required to be filed because at such time the actual number of Registrable Securities exceeds the number of Registrable Securities remaining under the Registration Statement and such Registrable Securities are not saleable under Rule 144, without limitation, the Company shall have twenty (20) Business Days to file such additional Registration Statement, and the Company shall use its commercially reasonable efforts to cause such additional Registration Statement to be declared effective by the Commission as soon as possible, but in no event later than sixty (60) days after such filing.

(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, the number of Registrable Securities to be registered on such Registration Statement will be reduced in the following order (i) first, by the Registrable Securities represented by the total number of Tripoint Warrant Shares, applied on a pro rata basis, (ii) second, by the Registrable Securities represented by the total number of Warrant Shares owned by the Holders, applied on a pro rata basis, and (iii) third, by the Registrable Securities represented by the Conversion Shares, applied on a pro rata basis.

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 date as permitted by the Commission.

(c) Each Holder agrees to furnish to the Company a completed Selling Stockholder Questionnaire not more than ten (10) Business Days following the date of this Agreement. Each Holder further agrees that it shall not be entitled to be named as a selling security holder in the Registration Statement or use the Prospectus for offers and resales of Registrable Securities at any time, unless such Holder has returned to the Company a completed and signed Selling Stockholder Questionnaire. If a Holder of Registrable Securities returns a Selling Stockholder Questionnaire after the deadline specified in the previous sentence, the Company shall use its commercially reasonable efforts to take such actions as are required to name such Holder as a selling security holder in the Registration Statement or any pre-effective or post-effective amendment thereto and to include (to the extent not theretofore included) in the Registration Statement the Registrable Securities identified in such late Selling Stockholder Questionnaire; provided that the Company shall not be required to file an additional Registration Statement solely for such shares. Each Holder acknowledges and agrees that the information in the Selling Stockholder Questionnaire will be used by the Company in the preparation of the Registration Statement and hereby consents to the inclusion of such information in the Registration Statement.

3. Registration Procedures.

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

(c) Notify the Holders of Registrable Securities 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) 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 (v) 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 case of the Prospectus, in the light of the circumstances under which they were made) not misleading.

(d) Use its commercially reasonable 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, 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, 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 resale of Registrable Securities, use its commercially reasonable efforts to register or qualify or cooperate with the selling Holders 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 Purchase Agreement 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 case of the Prospectus, in the light of the circumstances under which they were made) not misleading.

(k) Use its commercially reasonable efforts to cause all Registrable Securities relating to the Registration Statement, to continue to be quoted or listed on a 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 Purchase Agreement.

(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 a certified statement as to the number of shares of Common Stock beneficially owned by such Holder and the natural persons thereof that have voting and dispositive control over the Registrable Securities. During any periods that the Company is unable to meet its obligations hereunder with respect to the registration of the Registrable Securities solely because any Holder fails to furnish such information within five (5) Business Days of the Company’s request, any liquidated damages that are accruing at such time as to such Holder only shall be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the Company.

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) 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-Q and 10-K, then the Company may (x) postpone or suspend filing of a registration statement for a period not to exceed forty-five (45) consecutive days or (y) postpone or suspend effectiveness of a registration statement for a period not to exceed forty-five (45) consecutive days; provided that the Company may not postpone or suspend effectiveness of a registration statement under this Section 3(n) for more than ninety (90) days in the aggregate during any three hundred sixty (360) day period; provided, however, that no such postponement or suspension shall be permitted for consecutive twenty (20) day periods arising out of the same set of facts, circumstances or transactions.

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 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 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 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 incurred, arising out of or based upon any 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 arising out of or based 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) only for the lesser of (a) the actual damages incurred or (b) that amount as does not exceed the gross proceeds to such Holder as a result of the sale of his/her/its 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 promptly 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.

(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 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 statement of a material fact or 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 gross 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 applicable law.

6. Rule 144.

As long as any Holder owns Preferred Shares, 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 Shares, 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 reasonably 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. Each of the Company and each Holder agrees 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. The Company has not entered into, and shall not enter into on or after the date of this Agreement, 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. Other than the purchasers in the private placement that closed on April 22, 2010, the Company has not previously entered into any agreement that is 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 for Other Securities. Neither the Company nor any of its security holders 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 security holders, 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 for Registrable Securities. If at any time when there is not an effective Registration Statement covering (i) the Conversion Shares, or (ii) Warrant Shares, 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 ten (10) calendar 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 such Holder), the Company will cause the registration under the Securities Act of all Registrable Securities which the Company has been so requested to register by the Holder, to the extent requisite to permit the disposition of the Registrable Securities so to be registered, provided that if at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company may, at its election, give written notice of such determination to such Holder and, thereupon, (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from its obligation to pay expenses in accordance with Section 4 hereof), and (ii) in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities being registered pursuant to this Section 7(d) for the same period as the delay in registering such other securities. The Company shall include in such registration statement all or any part of such Registrable Securities such Holder requests to be registered; provided, however, that the Company shall not be required to register any Registrable Securities pursuant to this Section 7(d) that are eligible for sale pursuant to Rule 144 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 among such Holders based upon the number of Registrable Securities requested to be included in the registration in the order set forth in Section 2(b) hereof, 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). For purposes of this Section 7(d), Registrable Securities shall include any shares actually issued to the Purchasers pursuant to the Securities Escrow Agreement.

(e) Subordinated Registration Rights. Notwithstanding any other provision set forth herein, the Purchasers acknowledge and agree that the registration rights so granted to the Purchasers in this Agreement are subject in all respects to the full realization of the registration rights granted to the purchasers in the private placement that closed on April 22, 2010.

(f) Failure to File Registration Statement and Other Events. The Company and the Holders agree that the Holders will suffer damages if the Registration Statement is not filed on or prior to the Filing Date and not declared effective by the Commission on or prior to the Effectiveness Date and maintained in the manner contemplated herein during the Effectiveness Period or if certain other events occur. The Company and the Holders further agree that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if (A) 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 (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 immediately by a subsequent Registration Statement filed with and declared effective by the Commission in accordance with Section 2(a) hereof, or (E) the Company has breached Section 3(n) of this Agreement, or (F) trading in the Common Stock shall be suspended or if the Common Stock is no longer quoted on or is delisted from the NASDAQ (or other principal exchange on which the Common Stock is traded) for any reason for more than three (3) consecutive Business Days or twelve (12) Business Days in the aggregate for any twelve month period, (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 clauses (C) and (F) 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, being referred to as “Event Date”), then the Company shall pay an amount in cash as liquidated damages to each Holder equal to one percent (1%) of the amount of the Holder’s initial investment in the Units for each calendar month or portion thereof thereafter 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 ten percent (10%) of the amount of the Holder’s initial investment in the Units; and provided, further, that in the event the Commission does not permit all of the Registrable Securities to be included in the Registration Statement because of its application of Rule 415, liquidated damages payable pursuant to this Section shall only be payable by the Company based on the portion of the Holder’s initial investment in the Units that corresponds to the number of such Holder’s Registrable Securities permitted to be registered by the Commission in such Registration Statement pursuant to Rule 415. For further clarification, the parties understand that no liquidated damages shall be payable pursuant to this Section with respect to any Registrable Securities that the Company is not permitted to include on such Registration Statement due to the Commission’s application of Rule 415. In addition, no liquidated damages shall be payable with respect to Registrable Securities that may be sold pursuant to Rule 144. Notwithstanding anything to the contrary in this paragraph (e), if (a) any of the Events described in clauses (A), (B), (C), (D) or (F) shall have occurred, (b) on or prior to the applicable Event Date, the Company shall have exercised its rights under Section 3(n) hereof and (c) the postponement or suspension permitted pursuant to such Section 3(n) shall remain effective as of such applicable Event Date, then the applicable Event Date shall be deemed instead to occur on the second Business Day following the termination of such postponement or suspension. Liquidated damages payable by the Company pursuant to this Section 7(f) shall be payable on the Event Date and the first (1st) 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.

(g) 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 then outstanding Registrable Securities.

In the event that any signature is delivered by facsimile transmission, such signature shall create a valid binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature were the original thereof.

(l) Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York, without giving effect to any of the conflicts of law principles which would result in the application of the substantive law of another jurisdiction.

The Company and the Holders irrevocably consent to personal jurisdiction in the state and federal courts of the state of New York. The Company and the Holders consent to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.

(q) Independent Nature of Purchasers. The Company acknowledges that the obligations of each Purchaser under the Transaction Documents are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under the Transaction Documents.

The Company acknowledges that each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that it has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by the Purchasers. The Company acknowledges that such procedure with respect to the Transaction Documents in no way creates a presumption that the Purchasers are in any way acting in concert or as a group with respect to the Transaction Documents or the transactions contemplated hereby or thereby.
