Neither the Company nor any of the Subsidiaries, nor any Affiliates of the foregoing or any Person acting on the behalf of any of the foregoing, shall, directly or indirectly, make any offers or sales of any security or solicit any offers to purchase any security, under any circumstances that would require registration of any of the Securities under the 1933 Act or require stockholder approval of the issuance of any of the Securities.

z. Transfer Taxes . The Company shall be responsible for any liability with respect to any transfer, stamp or similar non-income Taxes that may be payable in connection with the execution, delivery and performance of this Agreement, the other Transaction Documents and the Certificate of Designations, including any such Taxes with respect to the issuance of the Preferred Shares, the Conversion Shares, the Warrants or the Warrant Shares.

bb. Short Sale . If at any time after the date that is 180 days after the Closing Date all of the Registrable Securities (as defined in the Registration Rights Agreement) are not registered and available for resale pursuant to an effective Registration Statement (as defined in the Registration Rights Agreement), for any reason whatsoever, including as a result of a Grace Period (as defined in the Registration Rights Agreement) or as a result of a limitation on the number of Registrable Securities that may be registered pursuant to Rule 415 under the 1933 Act, such Buyer may engage in any transaction constituting a Short Sale, so long as, immediately following such Short Sale, the aggregate short position (including aggregate open “put equivalent positions”) with respect to the Common Stock maintained by such Buyer and its Affiliates at such time does not exceed such Buyer’s Permitted Share Position. For purposes of this Section 4.bb the following terms have the following meanings: (i) “Permitted Share Position” means, with respect to any time of determination, the sum of (A) the number of Conversion Shares issuable upon conversion of Preferred Shares held by the applicable Buyer and its Affiliates (without regard to any limitations on conversion) at such time, plus (B) the number of Warrant Shares issuable upon exercise of the Warrants held by such Buyer and its Affiliates (without regard to any limitations on exercise) at such time, plus (C) the number of shares of Common Stock held by such Buyer and its Affiliates at such time; and (ii) “ Short Sale ” means a “short sale” (as defined in Regulation SHO under the 1934 Act) of shares of Common Stock or establishing an open “put equivalent position” (within the meaning of Rule 16a-1(h) under the 1934 Act) with respect to the Common Stock.

35

investors and any of the foregoing Persons’ agents or other representatives (including those retained in connection with the transactions contemplated by this Agreement) (collectively, the “ Indemnitees ”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitees is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “ Indemnified Liabilities ”), incurred by any Indemnitees as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company or any of the Subsidiaries in the Transaction Documents or the Certificate of Designations or any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company or any of the Subsidiaries contained in the Transaction Documents, the Certificate of Designations or any other certificate, instrument or document contemplated hereby or thereby, (c) any cause of action, suit or claim brought or made against such Indemnitees and arising out of or resulting from the execution, delivery, performance or enforcement of the Transaction Documents or the Certificate of Designations in accordance with the terms hereof or thereof or any other certificate, instrument or document contemplated hereby or thereby in accordance with the terms thereof (other than a cause of action, suit or claim brought or made against an Indemnitee by such Indemnitee’s owners, investors or affiliates), or (d) the HRP Transaction or any other transaction financed or to be financed in whole or in part directly with the proceeds of the issuance of the Securities. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law.

b. Indemnification Procedures . Each Indemnitee shall (i) give prompt written notice to the Company of any claim with respect to which it seeks indemnification or contribution pursuant to this Agreement ( provided , however , that the failure of the Indemnitee to promptly deliver such notice shall not relieve the Company of any liability, except to the extent that the Company is prejudiced in its ability to defend such claim) and (ii) permit the Company to assume the defense of such claim with counsel selected by the Company and reasonably satisfactory to the Indemnitee; provided, however , that any Indemnitee entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of the Indemnitee unless (A) the Company has agreed in writing to pay such fees and expenses, (B) the Company shall have failed to assume the defense of such claim within five (5) days of delivery of the written notice of the Indemnitee with respect to such claim or failed to employ counsel selected by the Company and reasonably satisfactory to the Indemnitee, or (C) in the reasonable judgment of the Indemnitee, based upon advice of its counsel, a conflict of interest may exist between the Indemnitee and the Company with respect to such claims (in which case, if the Indemnitee notifies the Company in writing that it elects to employ separate counsel at the expense of the Company, the Company shall not have the right to assume the defense of such claim on behalf of the Indemnitee). If the Company assumes the defense of the claim, it shall not be subject to any liability for any settlement or compromise made by the Indemnitee without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). In connection with any settlement negotiated by the Company, the Company shall not, and no Indemnitee shall be required by the Company to, (I) enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to the

36

Indemnitee of a release from all liability in respect to such claim or litigation, (II) enter into any settlement that attributes by its terms any liability, culpability or fault to the Indemnitee, or (III) consent to the entry of any judgment that does not include as a term thereof a full dismissal of the litigation or proceeding with prejudice. In addition, without the consent of the Indemnitee, the Company shall not consent to entry of any judgment or enter into any settlement which provides for any obligation or restriction on the part of the Indemnitee other than the payment of money damages which are to be paid in full by the Company. If the Company fails or elects not to assume the defense of a claim pursuant to clause (B) above, or is not entitled to assume or continue the defense of such claim pursuant to clause (C) above, the Indemnitee shall have the right without prejudice to its right of indemnification hereunder to, in its discretion exercised in good faith and upon advice of counsel, to contest, defend and litigate such claim and may settle such claim, either before or after the initiation of litigation, at such time and upon such terms as the Indemnitee deems fair and reasonable; provided that, at least five (5) days prior to any settlement, written notice of such Indemnitee’s intention to settle is given to the Company. If requested by the Company, the Indemnitee agrees (at no expense to the Indemnitee) to reasonably cooperate with the Company and its counsel in contesting any claim that the Company elects to contest.

9. GOVERNING LAW; MISCELLANEOUS .

a. Governing Law; Jurisdiction; Jury Trial . All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. Each party hereby irrevocably submits to the exclusive jurisdiction of the Chancery Court of the State of Delaware and any state appellate court therefrom sitting in New Castle County in the State of Delaware (or, if the Chancery Court of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

b. Counterparts; Execution . This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each

37

other party. A facsimile, PDF or other reproduction of this Agreement may be executed by one or more parties hereto, and an executed copy of this Agreement may be delivered by one or more parties hereto by facsimile, e-mail or other electronic transmission device pursuant to which the signature of or on behalf of such party can be seen, and such execution and delivery shall be considered valid, binding and effective for all purposes. The parties hereto hereby agree that no party shall raise the execution of facsimile, PDF or other reproduction of this Agreement, or the fact that any signature or document was transmitted or communicated by facsimile, e-mail or other electronic transmission device, as a defense to the formation of this Agreement.

c. Headings . The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

d. Severability . If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.

e. Entire Agreement; Amendments; Waivers . This Agreement supersedes all other prior oral or written agreements among each Buyer, the Company and the Subsidiaries, their affiliates and Persons acting on their behalf with respect to the matters discussed herein, and this Agreement and the instruments referenced herein contain the entire understanding of the parties hereto with respect to the matters covered herein and therein. No provision of this Agreement may be waived, modified, supplemented or amended other than by an instrument in writing signed by the Company and the holders of at least a majority of the then-outstanding Preferred Shares, or if prior to the Closing, by the Buyers listed on the Schedule of Buyers as being obligated to purchase at least a majority of the Preferred Shares. Any such amendment shall bind all holders of the Preferred Shares and the Warrants. No such amendment shall be effective to the extent that it applies to less than all of the holders of the Preferred Shares or Warrants then outstanding. No failure or delay on the part of a party in either exercising or enforcing any right under this Agreement shall operate as a waiver of, or impair, any such right. No single or partial exercise or enforcement of any such right shall preclude any other or further exercise or enforcement thereof or the exercise or enforcement of any other right. No waiver of any such right shall be deemed a waiver of any other right. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification or supplement of any provision of any of the Transaction Documents or the Certificate of Designations unless the same consideration also is offered to all of the parties hereto or to the other Transaction Documents or holders of the Preferred Shares or Warrants, as the case may be. For clarification purposes, this provision constitutes a separate right granted to each Buyer and is not intended for the Company to treat the Buyers as a class and shall not be construed in any way as the Buyers acting in concert or otherwise as a group with respect to the purchase, disposition or voting of securities or otherwise.

f. Notices . Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or electronically

g. Successors and Assigns . This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, including any purchasers of the Preferred Shares or the Warrants. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the holders of at least a majority of the Preferred Shares then outstanding, including by merger or consolidation, except pursuant to an Organic Change with respect to which the Company is in compliance with Section 2(c)(ii) of the Certificate of Designations. A Buyer may assign some or all of its rights hereunder without the consent of the Company; provided , however , that any such assignment shall not release such Buyer from its obligations hereunder unless such obligations are assumed by such assignee and the Company has consented to such assignment and assumption, which consent shall not be unreasonably withheld. Notwithstanding anything to the contrary contained in the Transaction Documents or the Certificate of Designations, the Buyers shall be entitled to pledge the Securities in connection with a bona fide margin account or other loan or financing arrangement secured by the Securities.

39

h. No Third Party Beneficiaries . This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns and, to the extent provided in Section   8 , each Indemnitee, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

i. Survival . Unless this Agreement is terminated under Section   9.k , the representations and warranties of the Company and the Buyers contained in Sections   2 and 3 , the agreements and covenants set forth in Sections   4 and 5 and this Section 9 , and the indemnification provisions set forth in Section   8 , shall survive the Closing. Each Buyer shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

j. Further Assurances . Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

k. Termination . In the event that the Closing shall not have occurred with respect to a Buyer on or before the third (3rd) Business Day following the date of this Agreement due to the Company’s or such Buyer’s failure to satisfy the conditions set forth in Sections   6 and  7 above (and the nonbreaching party’s failure to waive such unsatisfied condition(s)), the nonbreaching party shall have the option to terminate this Agreement with respect to such breaching party at the close of business on such date without liability of any party to any other party; provided , however , that if this Agreement is terminated pursuant to this Section   9.k , the Company shall be obligated to reimburse each of the Buyers (so long as such Buyer is not a breaching party) for its reasonable expenses (including attorneys’ fees and expenses) associated with the Closing.

l. Placement Agent . Except as set forth on Schedule 9.l , the Company represents and warrants to each of the Buyers that it has not engaged a placement agent, broker or financial advisor in connection with the transactions contemplated hereby and there are no fees, commissions or expenses payable to any broker, finder or agent relating to or arising out of the transactions contemplated hereby. The Company shall be responsible for the payment of any placement agent’s fees or broker’s commissions relating to or arising out of the transactions contemplated hereby. The Company shall pay, and hold each of the Buyers harmless against, any liability, loss or expense (including attorneys’ fees and out-of-pocket expenses) arising in connection with any claim for any such payment.

n. Remedies . The parties hereto agree that (i) irreparable harm would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and (ii) money damages or other legal remedies would not be an adequate remedy for any such harm. Each Buyer and each holder of the Securities shall have all rights and remedies set forth in the Transaction Documents and the

40

Certificate of Designations and all rights and remedies that such Buyers and holders have been granted at any time under any other agreement or contract and all of the rights that such Buyers and holders have under any law. Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security or proving actual damages), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law.

o. Payment Set Aside . To the extent that the Company or any of the Subsidiaries makes a payment or payments to the Buyers hereunder or pursuant to the Certificate of Designations or under any of the other Transaction Documents or the Buyers enforce or exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company or such Subsidiary, by a trustee, receiver or any other Person under any law (including any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

p. Independent Nature of Buyers . The obligations of each Buyer hereunder are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations of any other Buyer hereunder. Each Buyer shall be responsible only for its own representations, warranties, agreements and covenants hereunder. The decision of each Buyer to purchase the Securities pursuant to this Agreement has been made by such Buyer independently of any other Buyer and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any of the Subsidiaries which may have been made or given by any other Buyer or by any agent or employee of any other Buyer, and no Buyer or any of its agents or employees shall have any liability to any other Buyer (or any other Person or entity) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein, and no action taken by any Buyer pursuant hereto or thereto (including a Buyer’s purchase of Preferred Shares and Warrants at the Closing at the same time as any other Buyer or Buyers), shall be deemed to constitute the Buyers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Buyers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. Each Buyer shall be entitled to independently protect and enforce its rights, including the rights arising out of this Agreement, the other Transaction Documents and the Certificate of Designations, and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose.

q. Interpretative Matters . Unless the context otherwise requires, (i) all references to Sections, Schedules or Exhibits are to Sections, Schedules or Exhibits contained in or attached to this Agreement, (ii) each accounting term not otherwise defined in this Agreement has the meaning assigned to it in accordance with GAAP, (iii) words in the singular or plural include the singular and plural and pronouns stated in either the masculine, the

41

feminine or neuter gender shall include the masculine, feminine and neuter, (iv) the use of the word “including” in this Agreement shall be by way of example rather than limitation, and (v) the word “or” shall not be exclusive. All statements as to factual matters contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement, any of the other Transaction Documents or the Certificate of Designations in connection with the transactions contemplated hereby or thereby shall be deemed to be representations and warranties by the Company, as if made by the Company pursuant to Section   3 hereof, as of the date of such certificate or instrument (including for purposes of Section 7 hereof).

CERTIFICATE OF DESIGNATIONS, PREFERENCES

AND RIGHTS OF SERIES A CONVERTIBLE PREFERRED STOCK

OF

STEREOTAXIS, INC.

Stereotaxis, Inc. (the “ Company ”), a corporation organized and existing under the General Corporation Law of the State of Delaware, does hereby certify that, pursuant to authority conferred upon the Board of Directors of the Company by the Amended and Restated Certificate of Incorporation, as amended, of the Company, and pursuant to Section 151 of the General Corporation Law of the State of Delaware, the Board of Directors of the Company at a meeting duly held adopted resolutions (i) authorizing a series of the Company’s previously authorized preferred stock, par value $0.001 per share, and (ii) providing for the designations, preferences and relative, participating, optional or other rights, and the qualifications, limitations or restrictions thereof, of 24,000 shares of “ Series A Convertible Preferred Stock ” of the Company, as follows:

RESOLVED, that the Company is authorized to issue 24,000 shares of Series A Convertible Preferred Stock (the “ Preferred Shares ”), with a stated value of $1,000 per share, which shall have the following powers, designations, preferences and other special rights:

(1) Dividends . The Preferred Shares shall bear dividends at a rate of six percent (6.0%) per annum, which shall be cumulative and accrue daily from the Issuance Date (as defined below), on the Stated Value (as defined below). Such dividends shall accrue whether or not they have been declared and whether or not there are profits, surplus or other funds of the Company legally available for the payment of dividends. Such dividends shall not be paid or payable in cash, except in connection with any liquidation, dissolution or winding up of the Company or any redemption of the Preferred Shares pursuant to the terms hereof or as otherwise expressly set forth herein. In addition, subject to the rights of the holders, if any, of the shares of other classes or series of preferred stock of the Company that are of equal rank with the Preferred Shares as to payments of Preferred Funds (as defined below) (the “ Pari Passu Shares ”), if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of the Company’s common stock, par value $0.001 per share (“ Common Stock ”), by way of return of capital or otherwise (including any dividend or other distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement or other similar transaction) (a “ Distribution ”), at any time after the Effective Date, then, in each such case, each holder of Preferred Shares shall be entitled to receive such Distribution, and the Company shall make such Distribution to such holder, exactly as if such holder had converted such holder’s Preferred Shares in full (and, as a  

result, had held all of the Conversion Shares that such holder would have received upon such conversion, without regard to any limitations or restrictions on conversion) immediately prior to the record date for such Distribution, or if there is no record date therefor, immediately prior to the effective date of such Distribution (but without the holder’s actually having to so convert such holder’s Preferred Shares). For the avoidance of doubt, payments under the preceding sentence shall be made concurrently with the Distribution to the holders of Common Stock.

(2) Holder’s Conversion of Preferred Shares . A holder of Preferred Shares shall have the right, at such holder’s option, to convert the Preferred Shares into shares of Common Stock on the following terms and conditions:

(a) Conversion Right . At any time or times on or after the Issuance Date (as defined below), any holder of Preferred Shares shall be entitled to convert any whole number of Preferred Shares into fully paid and nonassessable shares (rounded to the nearest whole share in accordance with Section 2(h) ) of Common Stock, at the Conversion Rate (as defined below); provided, however, that in no event shall any holder be entitled or required to convert Preferred Shares for a number of Conversion Shares in excess of that number of Conversion Shares that, upon giving effect to such conversion, would cause the aggregate number of shares of Common Stock beneficially owned by the holder and its Affiliates and any other persons or entities whose beneficial ownership of shares of Common Stock would be aggregated with the holder’s for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “ 1934 Act ”), including shares held by any “group” of which the holder is a member (any such other persons and entities being referred to herein as “ Other Persons ”), to exceed the Beneficial Ownership Limitation. For purposes of the foregoing proviso, the aggregate number of shares of Common Stock beneficially owned by the holder and its Affiliates shall include the number of shares of Common Stock issuable upon conversion of the Preferred Shares with respect to which the determination of such proviso is being made, but shall exclude the shares of Common Stock that would be issuable upon (i) conversion of the remaining, nonconverted Preferred Shares beneficially owned by the holder and its Affiliates and any Other Persons and (ii) exercise, conversion or exchange of the unexercised, unconverted or unexchanged portion of any other securities of the Company beneficially owned by the holder and its Affiliates and any Other Persons (including any of the Warrants (as defined in the Securities Purchase Agreement) and any other warrants and any convertible preferred shares or notes) subject to a limitation on conversion, exercise or exchange analogous to the limitation contained herein. Subject to the immediately preceding sentence, for purposes of this Section 2(a) , beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act and applicable regulations of the Securities and Exchange Commission (“ SEC ”), and “group” shall have the meaning set forth in Section 13(d) of the 1934 Act and applicable regulations of the SEC. For purposes of this Certificate of Designations, in determining the number of outstanding shares Common Stock a holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-Q or Form 10-K filed under the 1934 Act, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or its transfer agent setting forth the number of shares of Common Stock outstanding. Upon the written request of any holder, the Company shall promptly, but in no event later than two (2) Business Days following the receipt of such request, confirm in writing to any such holder the number of shares Common Stock then outstanding. In any case, the number of outstanding shares Common Stock shall be determined after giving

2

effect to the conversion, exercise or exchange of securities of the Company and Preferred Shares by such holder and its Affiliates and any Other Persons, since the date as of which such number of outstanding shares of Common Stock was reported. Notwithstanding the foregoing, each holder of Preferred Shares shall have the sole right and obligation to determine whether the restrictions contained in this Section 2(a) apply to such holder. For purposes of determining the maximum number of shares of Common Stock that the Company may issue to a holder upon conversion of Preferred Shares, such holder’s delivery of a Conversion Notice (as defined in Section 2(e) ) with respect to such conversion shall constitute a representation by such holder that the holder has determined, based on the most recent public filings by the Company under the 1934 Act (or any differing information received from the Company as provided above), that upon the issuance of the shares of Common Stock to be issued to such holder, the shares of Common Stock beneficially owned by such holder and its Affiliates and any Other Persons will not exceed the Beneficial Ownership Limitation. The “ Beneficial Ownership Limitation ” shall be 4.99% of the number of shares of Common Stock immediately after giving effect to the issuance of shares of Common Stock upon such conversion of Preferred Shares; provided, however, that a holder of Preferred Shares, upon not less than 61 days’ prior notice to the Company, may increase the Beneficial Ownership Limitation applicable to such holder (but, for the avoidance of doubt, not to any subsequent holder of such Preferred Shares or to any other holder of Preferred Shares) to 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the conversion of Preferred Shares. No such increase shall be effective prior to the 61 ^st day after such notice is delivered to the Company.

(b) Conversion Rate . The number of shares of Common Stock issuable upon conversion of each of the Preferred Shares pursuant to Section (2)(a) shall be determined according to the following formula (the “ Conversion Rate ”):

(i) Holder’s Delivery Requirements . To convert Preferred Shares into full shares of Common Stock on any date (the “ Conversion Date ”), the holder thereof shall (A) transmit by electronic mail (or otherwise deliver), for receipt on or prior to 11:59 p.m. Eastern Time, on such date, a copy of a fully executed notice of conversion in the form attached hereto as Exhibit I (the “ Conversion Notice ”) to the Company and its designated transfer agent (the “ Transfer Agent ”) which Conversion Notice may specify that such conversion is conditioned upon consummation of a Major Transaction or Organic Change or any other transaction (such Major Transaction, Organic Change or other transaction, a “ Conversion Triggering Transaction ”), and (B) if required by Section 2(e)(vii) , surrender to a carrier, for overnight delivery to the Company as soon as practicable following such date, the original certificate(s) (the “ Preferred Stock Certificate(s) ”) representing the Preferred Shares being converted (or an indemnification undertaking with respect to such shares in the case of their loss, theft or destruction) (or, if the conversion is conditioned upon the consummation of a Conversion Triggering Transaction, on the date of (and immediately prior to) the consummation of such Conversion Triggering Transaction). Notwithstanding anything to the contrary contained herein, the holder may elect, in connection with a conversion that is contingent upon an Organic Change, that such conversion be effected contemporaneously with such Organic Change and that the holder will acquire and receive in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon such conversion of such holder’s Preferred Shares, such shares of stock, securities or assets of the acquiring entity in the Organic Change that would have been issued or payable in such Organic Change with respect to or in exchange for the number of shares that would have been acquirable and receivable upon such conversion of Preferred Shares as of the date of such Organic Change. In the event that the Conversion Shares issuable upon conversion are to be issued in any name other than that of the registered holder of the Preferred Shares being converted, each Preferred Stock Certificate representing such Preferred Shares surrendered for conversion shall be accompanied by instruments of transfer, in customary form duly executed by the holder or such holder’s duly authorized agent.

(ii) Company’s Response . Upon receipt by the Company of a copy of a Conversion Notice, the Company shall (A) immediately send, via electronic mail, a confirmation of receipt of such Conversion Notice to such holder and (B) no later than the second Business Day following the date of receipt (or, if the conversion is conditioned upon the consummation of a Conversion Triggering Transaction, immediately prior to the consummation of such Conversion Triggering Transaction) (the “ Share Delivery Date ”), as directed by such holder in the Conversion Notice, (I) provided that the holder of the Preferred Shares (or its designee) is eligible to receive shares through The Depository Trust Company (“ DTC ”), credit such aggregate number of shares of Common Stock to which the holder shall be entitled to the holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal At Custodian (DWAC) system, (II) issue and deliver to the address specified in the Conversion Notice, a certificate, registered in the name of the holder or its designee, representing the number of shares of Common Stock to which the holder shall be entitled or (III) issue such aggregate

8

number of shares of Common Stock to the holder or its designee through the Direct Registration System (DRS) of DTC and deliver a statement with respect thereto to the address specified in the Conversion Notice, and in any case, such shares of Common Stock shall not bear, or otherwise be subject to, the 1933 Act Legend (as defined in the Securities Purchase Agreement) as and to the extent provided in Section 2(f) hereof. If the number of Preferred Shares represented by the Preferred Stock Certificate(s) submitted for conversion is greater than the number of Preferred Shares being converted, then the Company shall, at its own expense, as soon as practicable and in no event later than four (4) Business Days after the Company shall have received the applicable Preferred Stock Certificate(s) (the “ Certificate Delivery Date ”), issue and deliver to the holder a new Preferred Stock Certificate representing the number of Preferred Shares not converted.

(iii) Dispute Resolution . In the case of a bona fide dispute as to the determination of the arithmetic calculation of the Conversion Rate, the Company shall promptly issue to the holder the number of shares of Common Stock that is not disputed and shall submit the disputed determinations or arithmetic calculations to the holder via facsimile and electronic mail within two (2) Business Days of receipt of such holder’s Conversion Notice. If such holder and the Company are unable to agree upon the determination of the arithmetic calculation of the Conversion Rate within two (2) Business Days of such disputed determination or arithmetic calculation being submitted to the holder, then the Company shall within three (3) Business Days submit via electronic mail the disputed arithmetic calculation of the Conversion Rate to its independent, outside accountant or other financial institution mutually acceptable to the Company and such holder. The Company shall direct the accountant or financial institution, as the case may be, to perform the determinations or calculations and notify the Company and the holder of the results as promptly as practicable, but in no event later than five (5) Business Days from the time it receives the disputed determinations or calculations. Such accountant’s or other institution’s determination or calculation, as the case may be, shall be binding upon all parties, absent manifest error.

(iv) Record Holder . The person or persons entitled to receive the shares of Common Stock issuable upon a conversion of Preferred Shares shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date.

(v) Company’s Failure to Timely Convert . In the event the Company shall (x) fail for any reason or no reason (other than as a result of a delay caused by such holder’s broker or agent, but in such case, only to the extent and for such period of time that such broker or agent’s action or inaction is the direct cause of such delay) to (A) credit the holder’s balance account with DTC for such number of shares of Common Stock to which the holder is entitled upon such exercise, (B) issue and deliver to a holder a certificate for the number of shares of Common Stock to which the holder is entitled upon the conversion of Preferred Shares, or (C) issue electronically in the name of the holder or its designee through the Direct Registration System (DRS) of DTC such number of shares of Common Stock to which the holder is entitled upon such conversion, in any such case on or prior to the Share Delivery Date, or (y) after the applicable SEC Effective Date, or at such other time as the Unrestricted Conditions have been met, issue any such shares of Common Stock bearing, or otherwise being subject to, the 1933 Act Legend, then the Company shall pay, as partial liquidated damages (but

9

not as a penalty and in addition to all other available remedies which such holder may pursue hereunder and under the Securities Purchase Agreement (including indemnification pursuant to Section 8 thereof)), to such holder on each day (I) after the Share Delivery Date that such conversion is not timely effected, in the case of clause (x) above, or (II) that such shares of Common Stock bear, or are otherwise subject to, the 1933 Act Legend, in the case of clause (y) above, in an amount equal to 0.25% of the product of (X) the sum of the number of shares of Common Stock not issued to the holder on a timely basis pursuant to Section 2(e)(ii) and to which such holder is entitled (or which bear, or are otherwise subject to, the 1933 Act Legend, as applicable) and (Y) the Weighted Average Price of the Common Stock on the last possible date which the Company could have issued such Common Stock to such holder without violating Section 2(e)(ii) . Alternatively, (a) subject to the dispute resolution provisions of Section 2(e)(iii) , at the election of the holder made in the holder’s sole discretion, the Company shall pay to the holder, in lieu of the partial liquidated damages referred to in the preceding sentence (but not as a penalty and in addition to all other available remedies which such holder may pursue hereunder and under the Securities Purchase Agreement (including indemnification pursuant to Section 8 thereof)), 110% of the amount by which (1) the holder’s total purchase price (including brokerage commissions, if any) for shares of Common Stock purchased to make delivery in satisfaction of a sale by the holder of the shares of Common Stock to which the holder is entitled but has not received upon conversion (or which bear, or are otherwise subject to, the 1933 Act Legend), exceeds (2) the net proceeds received by the holder from the sale of the shares of Common Stock to which the Holder is entitled but has not received upon such exercise (or which bear, or are otherwise subject to, the 1933 Act Legend), and (b) at the option of such holder, either (i) such conversion of Preferred Shares shall be cancelled and the Company shall reinstate such Preferred Shares and the related number of Conversion Shares with respect to such conversion, or (ii) the Company shall deliver to such holder the number of Conversion Shares that would have been issued had the Company timely complied with its conversion and delivery obligations hereunder.

(vi) Company’s Failure to Issue Certificates . In the event the Company shall fail to issue a new Preferred Stock Certificate representing the number of Preferred Shares to which such holder is entitled on or before the Certificate Delivery Date pursuant to Section 2(e)(ii) , then the Company shall pay, as partial liquidated damages (but not as a penalty and in addition to all other available remedies which such holder may pursue hereunder and under the Securities Purchase Agreement (including indemnification pursuant to Section 8 thereof)), to such holder on each day after the Certificate Delivery Date that such delivery of such Preferred Stock Certificates is not timely effected in an amount equal to 0.25% of the product of (A) the number of shares of Common Stock issuable upon conversion of the Preferred Shares to be represented by such Preferred Stock Certificate as of the last possible date which the Company could have issued such Preferred Stock Certificate to such holder without violating Section 2(e)(ii) and (B) the Weighted Average Price of the Common Stock on the last possible date which the Company could have issued such Preferred Stock Certificate to such holder without violating Section 2(e)(ii) , other than as a result of a delay caused by such holder’s broker or other agent, but in such case, only to the extent and for such period of time that such broker or agent’s action or inaction is the direct cause of such delay.

(vii) Book-Entry . Notwithstanding anything to the contrary set forth herein, upon conversion or redemption of Preferred Shares in accordance with the terms

10

hereof, the holder thereof shall not be required to physically surrender the certificate representing the Preferred Shares, if any, to the Company unless the full number of Preferred Shares represented by the certificate are being converted or redeemed. The holder and the Company shall maintain records showing the number of Preferred Shares so converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the holder and the Company, so as not to require physical surrender of the certificate representing the Preferred Shares, if any, upon each such conversion. In the event of any dispute or discrepancy, such records of the Company shall be controlling and determinative in the absence of manifest error. Notwithstanding the foregoing, if Preferred Shares represented by a certificate are converted as aforesaid, the holder may not transfer the certificate representing the Preferred Shares unless the holder first physically surrenders the certificate representing the Preferred Shares to the Company, whereupon the Company will forthwith issue and deliver upon the order of the holder a new certificate of like tenor, registered as the holder may request, representing in the aggregate the remaining number of Preferred Shares represented by such certificate. The holder and any assignee, by acceptance of a certificate, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of any Preferred Shares, the number of Preferred Shares represented by any such certificate may be less than the number of Preferred Shares stated of the face thereof. Each certificate for Preferred Shares shall bear the following legend:

ANY TRANSFEREE OF THIS CERTIFICATE SHOULD CAREFULLY REVIEW THE TERMS OF THE COMPANY’S CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS OF THE PREFERRED SHARES REPRESENTED BY THIS CERTIFICATE, INCLUDING SECTION 2(e)(vii) THEREOF. THE NUMBER OF PREFERRED SHARES REPRESENTED BY THIS CERTIFICATE MAY BE LESS THAN THE NUMBER OF PREFERRED SHARES STATED ON THE FACE HEREOF PURSUANT TO SECTION 2(e)(vii) OF THE CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS.

(f) Legend Removal . Notwithstanding anything to the contrary contained herein or in the Securities Purchase Agreement, upon the written request to the Company of a holder of a certificate or other instrument representing any Securities, the 1933 Act Legend shall be removed and the Company shall issue a certificate without the 1933 Act Legend to the holder of the Securities upon which it is stamped (or, in the case of any Conversion Shares being acquired upon conversion of any Preferred Shares, the Company shall issue the Conversion Shares without being subject to the 1933 Act Legend), if (i) such Securities are registered for resale under the 1933 Act (the date any such registration is declared effective by the SEC, the “ SEC Effective Date ”), (ii) in connection with a sale transaction, such holder provides the Company with an opinion of counsel, in a reasonably acceptable form, to the effect that a public sale, assignment or transfer of the Securities may be made without registration under the 1933 Act, (iii) such holder provides the Company reasonable assurances that the Securities have been or are being sold pursuant to Rule 144, or (iv) such holder certifies, on or after the date that is six (6) months after the date on which such holder acquired the Securities (or is deemed to have acquired the Securities under Rule 144, which in the case of Conversion Shares shall be the Closing Date (as defined in the Securities Purchase Agreement) on which the

11

Preferred Shares convertible into such Conversion Shares were issued), that such holder is not an “affiliate” of the Company (as defined in Rule 144) (collectively, the “ Unrestricted Conditions ”). The Company shall cause its counsel to issue a legal opinion to the transfer agent for the Common Stock promptly after the applicable SEC Effective Date, or at such other time as the Unrestricted Conditions have been met, if required by such transfer agent to effect the issuance of the applicable Preferred Shares or Conversion Shares without the 1933 Act Legend or removal of the 1933 Act Legend; provided, that in the event that the Company’s legal counsel determines in good faith that it is unable to issue such a legal opinion to the transfer agent as a result of an amendment to Rule 144 (e.g., to extend the holding period thereunder) or other applicable securities laws, rules or regulations subsequent to the Closing Date, the Company shall not be required to deliver such legal opinion until the earliest time as its counsel is able to do so. If the Unrestricted Conditions are met with respect to any Preferred Shares or Conversion Shares at the time of issuance of such Security, then such Security shall be issued free of the 1933 Act Legend. The Company agrees that, following the applicable SEC Effective Date with respect to any Securities or at such time as the Unrestricted Conditions are otherwise met or the 1933 Act Legend is otherwise no longer required under this Section   2(f) , any certificates representing such Securities bearing the 1933 Act Legend may be exchanged for certificates bearing no 1933 Act Legend. The Company shall, or shall cause the transfer agent for the Common Stock (as applicable), to deliver the certificates not bearing, or otherwise issue such Securities without being subject to, as applicable, such legend within three (3) Business Days after receipt of the legended Securities (or any certificate or instrument representing such Securities). The Company shall be responsible for the fees of its transfer agent and all of the DTC fees associated with any issuance hereunder.

(g) Company’s Failure to Timely Remove Legends . If, following the applicable SEC Effective Date or at such time as the Unrestricted Conditions are otherwise met or the 1933 Act Legend is otherwise no longer required under Section 2(f) hereof, the Company fails to deliver, or cause the transfer agent for the Common Stock to deliver (other than as a result of a delay caused by such holder’s broker or other agent, but in such case, only to the extent and for such period of time that such broker’s or agent’s action or inaction is the direct cause of such delay), the Preferred Shares or any Conversion Shares (including any certificate or instrument representing any such Preferred Shares or Conversion Shares) that do not bear and are not otherwise subject to the 1933 Act Legend within three (3) Business Days after receipt of legended Securities (or any certificate or instrument representing such Securities), then the Company shall pay, as partial liquidated damages (but not as a penalty and in addition to all other available remedies which such holder may pursue hereunder and under the Securities Purchase Agreement (including indemnification pursuant to Section 8 thereof)), to such holder on each day after such third (3rd) Business Day that such delivery of such unlegended Securities is not timely effected in an amount equal to 0.25% of the product of (A) the sum of (x) the number of shares of Common Stock, and (y) the number of shares of Common Stock issuable upon conversion of the Preferred Shares, in each case that were not so-delivered to the holder without being subject to the 1933 Act Legend, and (B) the Weighted Average Price of the Common Stock on the last possible date which the Company could have issued such unlegended Securities to such holder without violating Section 2(f) . For the avoidance of doubt, any payments pursuant to this Section 2(g) shall be duplicative of any payments made pursuant to Section2(e)(v) hereof upon any conversion of Preferred Shares.

12

(h) Fractional Shares . The Company shall not issue any fraction of a share of Common Stock upon any conversion. All shares of Common Stock (including fractions thereof) issuable upon conversion of more than one Preferred Share by a holder thereof shall be aggregated for purposes of determining whether the conversion would result in the issuance of a fraction of a share of Common Stock. If, after the aforementioned aggregation, the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up or down to the nearest whole share (with 0.5 rounded up).

(i) Taxes . The Company shall pay any and all taxes that may be payable with respect to the issuance and delivery of shares of Common Stock upon the conversion of the Preferred Shares, provided, that the foregoing shall not apply with respect to any individual or entity income taxes that are payable by any holder.

(3) Redemption at Option of Holders .

(a) Redemption Option Upon Major Transaction . In addition to all other rights of the holders of Preferred Shares contained herein, simultaneous with or after the occurrence of a Major Transaction, each holder of Preferred Shares shall have the right, at such holder’s option, but solely in accordance with the provisions of Section 3(e) , to require the Company to redeem all or a portion of such holder’s Preferred Shares at a price per Preferred Share equal to the greater of (i) the Liquidation Preference, and (ii) the product of (A) the Conversion Rate at such time, multiplied by (B) either (x) in the event of a Change of Control Transaction in which all of the outstanding Shares are exchanged for, or converted into the right to receive, consideration consisting solely of cash, then the consideration per Share payable in such Change of Control Transaction, or (y) otherwise, the Weighted Average Price of the Common Stock on the date immediately preceding the closing of the Major Transaction (the “ Major Transaction Redemption Price ”).

(b) Redemption Option Upon Triggering Event . In addition to all other rights of the holders of Preferred Shares contained herein, simultaneous with or after the occurrence of a Triggering Event (as defined below), each holder of Preferred Shares shall have the right, at such holder’s option, but solely in accordance with the provisions of Section 3(f) , to require the Company to redeem all or a portion of such holder’s Preferred Shares at a price per Preferred Share equal to the greater of (i) 120% of the Liquidation Preference, and (ii) the product of (A) the Conversion Rate on the date of such holder’s delivery of a Notice of Redemption at Option of Buyer Upon Triggering Event, multiplied by (B) the greater of (x) the Weighted Average Price of the Common Stock on the trading day immediately preceding such Triggering Event or (y) the Weighted Average Price of the Common Stock on the date of the holder’s delivery to the Company of a Notice of Redemption at Option of Buyer Upon Triggering Event (as defined below) or, if such date of delivery is not a trading day, the next date on which the exchange or market on which the Common Stock is traded is open (the “ Triggering Event Redemption Price ” and, collectively with the Major Transaction Redemption Price, the “ Redemption Price ”).

13

(c) “Major Transaction” . A “ Major Transaction ” shall be deemed to have occurred at such time as any of the following events:

(i) the consolidation, merger or other business combination of the Company with or into another Person (other than a consolidation, merger or other business combination in which holders of the Company’s voting power immediately prior to the transaction continue after the transaction to hold, directly or indirectly, the combined voting power of the surviving entity or entities entitled to vote generally for the election of a majority of the members of the board of directors (or their equivalent if other than a corporation) of such entity or entities) (a “ Change of Control Transaction ”);

(ii) the sale or transfer of (A) all or substantially all of the Company’s assets (including, for the avoidance of doubt, all or substantially all of the assets of the Company and the Subsidiaries in the aggregate), or (B) assets of the Company (including, for the avoidance of doubt, assets of the Company and the Subsidiaries in the aggregate) for consideration in an aggregate amount equal to more than 50% of the Enterprise Value (as defined above) of the Company;

(iii) the consummation of a purchase, tender or exchange offer made to and accepted by the holders of more than 50% of the outstanding shares of Common Stock;

(iv) the acquisition by any Person or “group” (within the meaning of Section 13(d)(3) or 14(d)(2) of the 1934 Act) of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the 1934 Act) of 50% or more of the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors; or

(v) any change in the composition of the board of directors of the Company such that the individuals who, as of the Effective Date, constituted the board of directors of the Company cease for any reason to constitute at least a majority of the board of directors of the Company.

(d) “Triggering Event” . A “ Triggering Event ” shall be deemed to have occurred at such time as any of the following events:

(i) A Registration Default (as defined in the Registration Rights Agreement) continues for a period of 10 consecutive trading days (provided, however, that the foregoing shall not constitute a “Triggering Event” so long as the Company is using its reasonable best efforts to cure such Registration Default);

(ii) suspension from quotation or listing or delisting of the Common Stock from the Principal Market for a period of 10 consecutive trading days;

(iii) the Company’s failure to deliver Conversion Shares within 15 days of the Conversion Date or the Company’s notice to any holder of Preferred Shares, including by way of public announcement, at any time, of its intention not to comply with proper requests for conversion of any Preferred Shares into shares of Common Stock, including due to any of the reasons set forth in Section 4(a) below;

14

(iv) following the applicable SEC Effective Date or at such time as the Unrestricted Conditions are otherwise met or the 1933 Act Legend (as defined in the Securities Purchase Agreement) is otherwise no longer required under Section   2(f) of this Certificate of Designations and a request for removal has been made by the holder, the Company’s failure to deliver, or cause the transfer agent for the Common Stock to deliver, the Preferred Shares or any Conversion Shares (including any certificate or instrument representing any such Preferred Shares or Conversion Shares) without bearing or otherwise being subject to the restrictive legend either (x) in the case of a conversion, within 15 days of the Conversion Date, or (y) otherwise, within 15 days after receipt of the legended Securities;

(v) the Company breaches any representation, warranty, covenant or other term or condition of the Securities Purchase Agreement, the Registration Rights Agreement, the Warrants, this Certificate of Designations or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated thereby or hereby, except to the extent that such breach would not have a Material Adverse Effect (as defined in Section 3(a) of the Securities Purchase Agreement) and except, in the case of a breach of a covenant which is curable, only if such breach continues for a period of at least 30 days.

(e) Mechanics of Redemption at Option of Buyer Upon Major Transaction . No later than 20 days prior to the consummation of a Major Transaction, but not prior to the public announcement of such Major Transaction, the Company shall deliver written notice thereof via electronic mail and overnight courier (a “ Notice of Major Transaction ”) to each holder of Preferred Shares. At any time during the period beginning after receipt of a Notice of Major Transaction (or, in the event a Notice of Major Transaction is not delivered at least 30 days prior to a Major Transaction, at any time on or after the date which is 30 days prior to a Major Transaction) and ending on the later of (x) five Business Days prior to the consummation of such Major Transaction, and (y) ten trading days following the Company’s delivery of a Notice of Major Transaction, any holder of Preferred Shares may require the Company to redeem all or a portion of the holder’s Preferred Shares by delivering written notice thereof (a “ Notice of Redemption at Option of Buyer Upon Major Transaction ”) to the Company. The Notice of Redemption at Option of Buyer Upon Major Transaction shall indicate (i) the number of Preferred Shares that such holder is submitting for redemption, and (ii) the applicable Major Transaction Redemption Price, as calculated pursuant to Section 3(a) . In the event a holder of Preferred Shares delivers to the Company a Notice of Redemption at Option of Buyer Upon Major Transaction, then prior to the consummation of such Major Transaction, the Company shall make arrangements (which may include obtaining a written agreement from the acquiring entity, as applicable, that payment of the Major Transaction Redemption Price shall be made to the holder upon the consummation of the Major Transaction) satisfactory to the holder, as determined by the holder in its sole discretion, that the Major Transaction Redemption Price will be paid, in full, to the holder concurrently with the consummation of such Major Transaction. The Company hereby acknowledges and agrees that each such holder shall have the right to apply for an injunction in any state or federal courts sitting in the State of Delaware to prevent the closing of the Major Transaction unless and until such arrangements satisfactory to the holder have been made.

15

(f) Mechanics of Redemption at Option of Buyer Upon Triggering Event . Within two Business Days after the occurrence of a Triggering Event, the Company shall deliver written notice thereof via electronic mail and overnight courier (a “ Notice of Triggering Event ”) to each holder of Preferred Shares. At any time after the earlier of a holder’s receipt of a Notice of Triggering Event and such holder becoming aware of a Triggering Event, any holder of Preferred Shares may require the Company to redeem all or a portion of the holder’s Preferred Shares by delivering written notice thereof (a “ Notice of Redemption at Option of Buyer Upon Triggering Event ”) to the Company, which Notice of Redemption at Option of Buyer Upon Triggering Event shall indicate (i) the number of Preferred Shares that such holder is submitting for redemption, and (ii) the applicable Triggering Event Redemption Price, as calculated pursuant to Section 3(b) .

(g) Payment of Redemption Price . Upon the Company’s receipt of a Notice(s) of Redemption at Option of Buyer Upon Triggering Event or a Notice(s) of Redemption at Option of Buyer Upon Major Transaction from any holder of Preferred Shares, the Company shall promptly but in no event later than two Business Days, notify each such holder by electronic mail and facsimile of the Company’s receipt of such Notice(s) of Redemption at Option of Buyer Upon Triggering Event or Notice(s) of Redemption at Option of Buyer Upon Major Transaction and each holder which has sent such a notice shall promptly submit, if required by Section (2)(e)(vii) , to the Company or its Transfer Agent such holder’s Preferred Stock Certificates, if any, which such holder has elected to have redeemed. The Company shall deliver the applicable Triggering Event Redemption Price, in the case of a redemption pursuant to Section 3(f) , to such holder within ten (10) Business Days after the Company’s receipt of a Notice of Redemption at Option of Buyer Upon Triggering Event and, in the case of a redemption pursuant to Section 3(e) , the Company shall deliver the applicable Major Transaction Redemption Price contemporaneously with the consummation of the Major Transaction; provided that, if required by Section 2(e)(vii) , a holder’s Preferred Stock Certificates shall have been so delivered to the Company; provided further that if the Company is unable to redeem all of the Preferred Shares to be redeemed, the Company shall redeem an amount from each holder of Preferred Shares being redeemed equal to such holder’s pro-rata amount (based on the number of Preferred Shares held by such holder relative to the number of Preferred Shares outstanding) of all Preferred Shares being redeemed. If the Company shall fail to redeem all of the Preferred Shares submitted for redemption (other than pursuant to a bona fide dispute as to the arithmetic calculation of the Redemption Price), in addition to any remedy such holder of Preferred Shares may have under this Certificate of Designation, the Securities Purchase Agreement and the Registration Rights Agreement, the applicable Redemption Price payable in respect of such unredeemed Preferred Shares shall bear interest at the rate of 1.25% per month (prorated for partial months) until paid in full. In the event that the Company fails to pay such unpaid applicable Redemption Price in full to a holder of Preferred Shares by the 10 ^th Business Day following delivery of a Notice of Redemption at Option of Buyer Upon Triggering Event or contemporaneously with the consummation of the Major Transaction, such holder shall have the option to, in lieu of redemption, require the Company to promptly return to such holder(s) all of the Preferred Shares that were submitted for redemption by such holder(s) under this Section 3 and for which the applicable Redemption Price has not been paid, by sending written notice thereof to the Company via electronic mail (the “ Void Optional Redemption Notice ”). Upon the Company’s receipt of such Void Optional Redemption Notice(s) prior to payment of the full applicable Redemption Price to such holder, (i) the Notice(s) of Redemption

16

at Option of Buyer Upon Triggering Event or the Notice(s) of Redemption at Option of Buyer Upon Major Transaction, as the case may be, shall be null and void with respect to those Preferred Shares submitted for redemption and for which the applicable Redemption Price has not been paid, (ii) the Company shall immediately return any Preferred Stock Certificates submitted to the Company by each holder for redemption under this Section 3(g) and for which the applicable Redemption Price has not been paid and (iii) the Conversion Price of such returned Preferred Shares shall be adjusted to the lesser of (A) the Conversion Price as in effect on the date on which the Void Optional Redemption Notice(s) is delivered to the Company and (B) the lowest Weighted Average Price for the Common Stock during the period beginning on the date on which the Notice(s) of Redemption of Option of Buyer Upon Major Transaction or the Notice(s) of Redemption at Option of Buyer Upon Triggering Event, as the case may be, was delivered to the Company and ending on the date on which the Void Optional Redemption Notice(s) was delivered to the Company; provided that no adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect. Notwithstanding the foregoing, in the event of a bona fide dispute as to the determination of the Weighted Average Price or the arithmetic calculation of the Redemption Price, such dispute shall be resolved pursuant to Section 2(e)(iii) above with the term “Redemption Price” being substituted for the term “Conversion Rate.” A holder’s delivery of a Void Optional Redemption Notice and exercise of its rights following such notice shall not effect the Company’s obligations to make any payments which have accrued prior to the date of such notice.

(4) Redemption at the Company’s Election Upon Change of Control .

(a) Redemption . At any time or times on or after the date the Company publicly discloses a Change of Control Transaction, the Company shall have the right, in its sole discretion, to require that all, but not less than all, of the outstanding Preferred Shares be redeemed ( “Redemption at Company’s Election” ) at a price per Preferred Share equal to the greater of (i) the Liquidation Preference, and (ii) the product of (A) the Conversion Rate at such time, multiplied by (B) either (x) in the event of a Change of Control Transaction in which all of the outstanding Shares are exchanged for, or converted into the right to receive, consideration consisting solely of cash, then the consideration per Share payable in such Change of Control Transaction, or (y) otherwise, the Weighted Average Price of the Common Stock on the date immediately preceding the closing of the Change of Control Transaction (the “Change of Control Redemption Price” ); provided that the Conditions to Redemption at the Company’s Election (as set forth below) are satisfied. The Company shall exercise its right to Redemption at Company’s Election by providing each holder of Preferred Shares written notice ( “Notice of Redemption at Company’s Election” ) after the public disclosure of a Change of Control Transaction and at least 30 trading days prior to the date of consummation of the Change of Control Transaction (“ Company’s Election Redemption Date ”). The Notice of Redemption at Company’s Election shall indicate the anticipated Company’s Election Redemption Date. If the Company has exercised its right of Redemption at Company’s Election and the conditions to such Redemption at Company’s Election have been satisfied, then all Preferred Shares outstanding at the time of the consummation of the Change of Control Transaction shall be redeemed as of the Company’s Election Redemption Date by payment by the Company to each holder of Preferred Shares of the Change of Control Redemption Price concurrent with the closing of the Change of Control Transaction. All holders of Preferred Shares shall thereupon and within five Business Days after the Company’s Election Redemption Date, or such earlier

17

date as the Company and each holder of Preferred Shares mutually agree, surrender all outstanding Preferred Stock Certificates, if any, duly endorsed for cancellation, to the Company. In the event the Company delivers a Notice of Redemption at Company’s Election, then prior to the consummation of such Change of Control Transaction, the Company shall make arrangements (which may include obtaining a written agreement from the acquiring entity, as applicable, that payment of the Change of Control Redemption Price shall be made to the holder upon the consummation of the Change of Control Transaction) satisfactory to the holder, as determined by the holder in its sole discretion, that the Change of Control Redemption Price will be paid, in full, to the holder concurrently with the consummation of such Change of Control Transaction. The Company hereby acknowledges and agrees that each such holder shall have the right to apply for an injunction in any state or federal courts sitting in the State of Delaware to prevent the closing of the Change of Control unless and until such arrangements satisfactory to the holder have been made. If the Company fails to pay the full Change of Control Redemption Price with respect to any Preferred Shares concurrently with the closing of the Change of Control Transaction, then the Redemption at Company’s Election shall be null and void with respect to such Preferred Shares and the holder of such Preferred Shares shall be entitled to all the rights of a holder of outstanding Preferred Shares set forth in this Certificate of Designations. Notwithstanding the foregoing, in the event of a bona fide dispute as to the determination of the Weighted Average Price or the arithmetic calculation of the Change of Control Redemption Price, such dispute shall be resolved pursuant to Section 2(e)(iii) above with the term “Change of Control Redemption Price” being substituted for the term “Conversion Rate.” “ Conditions to Redemption at the Company’s Election ” means the following conditions: (1) on each day during the period beginning 60 trading days prior to the date of the Company’s Election Redemption Date and ending on and including the Company’s Election Redemption Date, the Common Stock shall have been listed or quoted, as applicable, on the Principal Market and shall not have been suspended from trading; (2) during the period beginning on the Issuance Date and ending on and including the Company’s Election Redemption Date, the Company shall have delivered Conversion Shares upon conversion of the Preferred Shares to the holders of the Preferred Shares (without bearing or otherwise being subject to the 1933 Act Legend) on a timely basis as set forth in Sections 2(e)(ii) and Section 2(f) hereof; and (3) there has not been any Triggering Event and the Company has otherwise satisfied its obligations and is not in default under this Certificate of Designations, the Securities Purchase Agreement, the Warrants and the Registration Rights Agreement. Notwithstanding the above, any holder of Preferred Shares may convert such shares (including Preferred Shares selected for redemption) into Common Stock pursuant to Section 2(a) on or prior to the date immediately preceding the Company’s Election Redemption Date.

(b) Company Must Have Immediately Available Funds . The Company shall not be entitled to send any Notice of Redemption at Company’s Election pursuant to Section 4(a) above and begin the redemption procedure thereunder unless it has, or will have upon consummation of the Change of Control Transaction, the full amount of the Change of Control Redemption Price in cash, available in a demand or other immediately available account in a bank or similar financial institution.

(5) [Reserved]

(6) Redemption Price Payable Out of Cash Legally Available therefor; Priority of Payment . Notwithstanding anything herein to the contrary, any redemption of Preferred Shares pursuant to the terms of this Certificate of Designations (any such redemption, a “ Redemption ”) shall be payable out of any cash legally available therefor. At the time of any Redemption, the Company shall take all actions required or permitted under Delaware law to permit the Redemption and to make funds legally available for such Redemption. To the extent that the Company has insufficient funds to redeem all of the Preferred Shares subject to such Redemption upon the Redemption, the Company shall use available funds to redeem a pro rata portion of each holder’s Preferred Shares subject to such Redemption, to the extent permissible under Delaware law. Any payments provided for in Section 3 or Section 4 in connection with a Redemption shall have priority to payments to holders of Common Stock or any other class of capital stock of the Company (other than the holders of Preferred Shares) in connection with a Major Transaction or Change of Control Transaction, as applicable, and, the Company shall not (and shall cause the acquiring entity in an Organic Change to not) make any payment to any holder of Common Stock or any other class of capital stock of the Company (other than the holders of Preferred Shares) unless and until the Company (or such acquiring entity, as applicable) has satisfied all of the Company’s obligations hereunder with respect to any Redemption as to which a Notice of Redemption at Option of Buyer Upon Major Transaction or Notice of Redemption at Company’s Election, as applicable, has been delivered prior to the consummation of such Major Transaction or Change of Control Transaction, as applicable.

(7) Reissuance of Certificates . Subject to Section 2(e)(vii) , in the event of a conversion or redemption pursuant to this Certificate of Designations of less than all of the Preferred Shares represented by a particular Preferred Stock Certificate, the Company shall promptly cause to be issued and delivered to the holder of such Preferred Shares a preferred stock certificate representing the remaining Preferred Shares which have not been so converted or redeemed.

(8) Reservation of Shares . The Company shall, so long as any of the Preferred Shares are outstanding, reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Preferred Shares, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of all of the Preferred Shares then outstanding (without regard to any limitations on conversions); provided that the number of shares of Common Stock so reserved shall at no time be less than 100% of the number of shares of Common Stock for which the Preferred Shares are at any time convertible. The number of shares of Common Stock reserved for conversions of the Preferred Shares shall be allocated pro rata among the holders of the Preferred Shares based on the number of Preferred Shares held by each holder. In the event a holder shall sell or otherwise transfer any of such holder’s Preferred Shares, each transferee shall be allocated a pro rata portion of the number of reserved shares of Common Stock reserved for such transferor. Any shares of Common Stock reserved and which remain allocated to any person or entity which does not hold any Preferred Shares shall be allocated to the remaining holders of Preferred Shares, pro rata based on the number of Preferred Shares then held by such holder.

(9) Voting Rights . The holders of Preferred Shares shall be entitled to notice of all stockholder meetings at which holders of Common Stock shall be entitled to vote. Each holder of Preferred Shares shall be entitled to vote such Preferred Shares on an as-converted

19

basis (based upon the aggregate number of Conversion Shares into which such holder’s Preferred Shares are then convertible, giving effect to any limitations on conversion set forth in Section 2(a) above ) with respect to all matters on which holders of Common Stock are entitled to vote and shall otherwise be entitled to such voting rights as required by applicable law.

(10) Liquidation, Dissolution, Winding-Up . In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company, the holders of the Preferred Shares shall be entitled to receive in cash out of the assets of the Company, whether from capital or from earnings available for distribution to its stockholders (the “ Preferred Funds ”), before any amount shall be paid to the holders of any of the capital stock of the Company of any class junior in rank to the Preferred Shares in respect of the preferences as to the distributions and payments on the liquidation, dissolution and winding up of the Company, an amount per Preferred Share equal to the Liquidation Preference; provided that, if the Preferred Funds are insufficient to pay the full amount due to the holders of Preferred Shares and holders of Pari Passu Shares, then each holder of Preferred Shares and Pari Passu Shares shall receive a percentage of the Preferred Funds equal to the full amount of Preferred Funds payable to such holder as a liquidation preference, in accordance with their respective Certificate of Designations, Preferences and Rights, as a percentage of the full amount of Preferred Funds payable to all holders of Preferred Shares and Pari Passu Shares. Thereafter, the holders of the Preferred Shares shall share ratably in any distributions and payments of any remaining assets of the Company, on an as-converted basis (without giving effect to any limitations on conversion set forth in this Certificate of Designations), with the holders of Common Stock. The purchase or redemption by the Company of stock of any class, in any manner permitted by law, shall not, for the purposes hereof, be regarded as a liquidation, dissolution or winding up of the Company. Neither the consolidation or merger of the Company with or into any other Person, nor the sale or transfer by the Company of all or substantially all of its assets, shall, for the purposes hereof, be deemed to be a liquidation, dissolution or winding up of the Company.

(11) Preferred Rank; Participation . All Preferred Shares rank senior to the Common Stock in respect to the preferences as to distributions and payments upon the liquidation, dissolution and winding up of the Company. The rights of the shares of Common Stock shall be subject to the preferences and relative rights of the Preferred Shares. Beginning on the Closing Date and ending on the date that is sixty-one (61) months after the Closing Date, so long as at eight thousand (8,000) of the Preferred Shares issued on the Closing Date remain outstanding, without the prior express written consent of the holders of not less than a majority of the then outstanding Preferred Shares, the Company shall not authorize or issue additional or other capital stock that is of rank senior to or pari passu with the Preferred Shares in respect of the preferences as to dividends or distributions or payments upon the liquidation, dissolution or winding up of the Company. Without the prior express written consent of the holders of not less than a majority of the then outstanding Preferred Shares, the Company shall not hereafter (i) authorize or make any amendment to the Company’s Amended and Restated Certificate of Incorporation or bylaws, or (ii) file any resolution of the Board of Directors of the Company with the Secretary of State of the State of Delaware, in the case of (i) or (ii) containing any provisions which would adversely affect or otherwise impair the rights or relative priority of the holders of the Preferred Shares relative to the holders of the Common Stock or the holders of any other class of capital stock of the Company. Except to the extent adequate provision is made for, as determined by the holders of not less than a majority of the then outstanding Preferred Shares, as

20

expressly provided elsewhere in this Certificate of Designations, in the event of the merger or consolidation of the Company with or into another corporation, the Preferred Shares shall maintain their relative powers, designations and preferences provided for herein.

(12) Restriction on Redemption and Cash Dividends with respect to Other Capital Stock . Until all of the Preferred Shares have been converted or redeemed as provided herein, the Company shall not, directly or indirectly, redeem, or declare or pay any cash dividend or distribution on, its Common Stock without the prior express written consent of the holders of not less than a majority of the then outstanding Preferred Shares; provided that the foregoing shall not limit the right of the Company to effectuate (i) any “net issuance” or “net settlement” features in any convertible security outstanding as of the date hereof and set forth on Schedule 3.c to the Securities Purchase Agreement, so long as such security is not amended or otherwise modified after the date hereof, (ii) any cashless exercise provision or to satisfy any tax withholding right upon the exercise of any options or the vesting of any equity awards issued pursuant to an Approved Stock Plan or (iii) so long as such transaction is approved by the Board of Directors of the Company following the Closing Date, a single transaction or series of related transactions, involving one of the Company’s existing investors that beneficially owns not less than an aggregate of 1,000,000 shares of Common Stock as of the date of the Securities Purchase Agreement, to close within ninety (90) days of the Closing Date, provided that the Company shall not have any net cash outflows in connection with such transaction, or series of related transactions.

(13) Vote to Change the Terms of or Issue Preferred Shares; Amendment . The affirmative vote at a meeting duly called for such purpose or the written consent without a meeting, of the holders of not less than a majority of the then outstanding Preferred Shares, shall be required for (a) any change to this Certificate of Designations or the Company’s Amended and Restated Certificate of Incorporation which would amend, alter, change, repeal or otherwise affect any of the powers, designations, preferences and rights of the Preferred Shares, or (b) any issuance of Preferred Shares other than pursuant to the Securities Purchase Agreement. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification or supplement of any provision of this Certificate of Designations unless the same consideration also is offered to all of the holders of the Preferred Shares. For clarification purposes, this provision constitutes a separate right granted to each holder of Preferred Shares and is not intended for the Company to treat such holders as a class and shall not be construed in any way as such holders acting in concert or otherwise as a group with respect to the purchase, disposition or voting of securities or otherwise.

(14) [Reserved]

(15) Lost or Stolen Certificates . Upon receipt by the Company of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of any Preferred Stock Certificates representing the Preferred Shares, and, in the case of loss, theft or destruction, of an indemnification undertaking by the holder to the Company and, in the case of mutilation, upon surrender and cancellation of the Preferred Stock Certificate(s), the Company shall execute and deliver new preferred stock certificate(s) of like tenor and date; provided, however, the Company shall not be obligated to re-issue preferred stock certificates if the holder contemporaneously requests the Company to convert the Preferred Shares represented thereby into Common Stock.

21

(16) Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief . The remedies provided in this Certificate of Designations shall be cumulative and in addition to all other remedies available under this Certificate of Designations, at law or in equity (including a decree of specific performance and/or other injunctive relief), no remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy and nothing herein shall limit a holder’s right to pursue actual damages for any failure by the Company to comply with the terms of this Certificate of Designations. The Company covenants to each holder of Preferred Shares that there shall be no characterization concerning this instrument other than as expressly described herein. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the holder thereof and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder may cause irreparable harm to the holders of the Preferred Shares by vitiating the intent and purpose of the transactions contemplated by this Certificate of Designations and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach by the Company of the provisions of this Certificate of Designations, the holders of the Preferred Shares shall be entitled, in addition to all other available remedies, to an injunctive order and/or injunction restraining any breach and requiring immediate compliance, without the necessity of showing economic loss and without any bond or other security being required.

(17) Payment Set Aside . To the extent that the Company or any of the Subsidiaries makes a payment or payments to the holders of Preferred Shares hereunder or such holders enforce or exercise their rights hereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company or such Subsidiary, by a trustee, receiver or any other Person under any law (including any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

(18) Specific Shall Not Limit General; Construction . No specific provision contained in this Certificate of Designations shall limit or modify any more general provision contained herein. This Certificate of Designations shall be deemed to be jointly drafted by the Company and all holders of Preferred Shares and shall not be construed against any person as the drafter hereof.

(19) Failure or Indulgence Not Waiver . No failure or delay on the part of a holder of Preferred Shares in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.

(20) Notice . Whenever notice is required to be given, it shall be given in accordance with Section 9.f of the Securities Purchase Agreement.

- 4 -

registration of the resale of Registrable Securities hereunder) covering the resale of the Registrable Securities. The Initial Registration Statement prepared pursuant hereto shall register for resale at least the number of Registrable Securities equal to the Initial Required Registration Amount determined as of the date the Initial Registration Statement is initially filed with the SEC (subject to subsequent reduction if directed by the staff of the SEC). The Company shall use its best efforts to have the Initial Registration Statement declared effective by the SEC as soon as practicable, but in no event later than the Initial Effectiveness Deadline.

b. Cutback Mandatory Registrations  The Company shall prepare, and, as soon as practicable, but in no event later than each Cutback Filing Deadline, file with the SEC a Cutback Registration Statement on Form S-1 (or on Form S-3, if Form S-3 is then available for the registration of the resale of Registrable Securities hereunder) covering the resale of the number of Cutback Registrable Securities equal to the Cutback Required Registration Amount. To the extent the staff of the SEC does not permit all of the Cutback Registrable Securities to be registered on a Cutback Registration Statement, the Company shall file Cutback Registration Statements successively trying to register on each such Cutback Registration Statement the maximum number of remaining Cutback Registrable Securities until all of the Cutback Registrable Securities have been registered with the SEC. Each Cutback Registration Statement prepared pursuant hereto shall register for resale at least that number of shares of Common Stock equal to the Cutback Required Registration Amount as of the date such Cutback Registration Statement is initially filed with the SEC. The Company shall use its best efforts to have each Cutback Registration Statement declared effective by the SEC as soon as practicable following the filing thereof, but in no event later than 90 days following the filing thereof (a “ Cutback Effectiveness Deadline ”).

c. Allocation of Registrable Securities . The number of Registrable Securities included in any Registration Statement shall be allocated pro rata among the Investors based on the number of Registrable Securities held by each Investor that are to be included in such Registration Statement (without giving effect to any limitations imposed by the SEC). In the event that an Investor sells or otherwise transfers any of such Investor’s Registrable Securities, each transferee shall be allocated a pro rata portion of the then remaining number of Registrable Securities included in such Registration Statement for such transferor. Any Registrable Securities included in a Registration Statement and which remain allocated to any Person that ceases to hold any Registrable Securities covered by such Registration Statement shall be allocated to the remaining Investors, pro rata based on the number of Registrable Securities then held by such Investors which are covered by such Registration Statement. For purposes hereof, the number of Registrable Securities held by an Investor includes all Registrable Securities issuable upon conversion of Preferred Shares and upon exercise of Warrants, in each case held by such Investor, without regard to any limitation on the conversion of the Preferred Shares or on the exercise of the Warrants. In no event shall the Company include any securities other than Registrable Securities in any Registration Statement without the prior written consent of the Required Holders.

d. Legal Counsel . The Required Holders shall have the right to select one legal counsel to review and oversee any registration pursuant to this Section 2 (“ Legal Counsel ”), which shall be Katten Muchin Rosenman LLP or such other counsel as thereafter designated by the Required Holders. The Company shall reasonably cooperate with Legal Counsel in performing the Company’s obligations under this Agreement.

- 5 -

e. Ineligibility for Form S-3 . In the event that Form S-3 is not available for the registration of the resale of any Registrable Securities hereunder, (i) the Company shall undertake to file, within sixty (60) days of such time as such form is available for such registration, a post-effective amendment to the existing Registration Statement, or otherwise file a Registration Statement on Form S-3, registering such Registrable Securities on Form S-3; provided that the Company shall maintain the effectiveness of the existing Registration Statement then in effect until such time as a Registration Statement (or post-effective amendment) on Form S-3 covering such Registrable Securities has been declared effective by the SEC, and (ii) the Company shall provide that any Registration Statement on Form S-1 filed hereunder shall incorporate documents by reference (including by way of forward incorporation by reference) to the maximum extent possible.

f. Sufficient Number of Shares Registered . In the event the number of shares available under a Registration Statement filed pursuant to Section 2(a) is insufficient to cover all of the Registrable Securities required to be covered by such Registration Statement or an Investor’s allocated portion of the Registrable Securities pursuant to Section 2(c) , the Company shall, as soon as practicable, but in any event (other than with respect to Cutback Shares) not later than 30 days after the necessity therefor arises, or (if later) the first date on which the Company is then permitted to file such Registration Statement by the SEC (a “ Subsequent Filing Deadline ”) amend the applicable Registration Statement, or file a new Registration Statement (on the short form available therefor, if applicable), or both, so as to cover Registrable Securities consisting of at least that number of shares of Common Stock equal to 100% of the sum of (i) the number of then-outstanding Conversion Shares and Warrant Shares that constitute Registrable Securities, (ii) the number of Registrable Securities issuable upon conversion of then-outstanding Preferred Shares, and (iii) the number of Registrable Securities issuable upon exercise of then-outstanding Warrants, in each case as of the trading day immediately preceding the date of the filing of such amendment or new Registration Statement. The Company shall use its best efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof, but in any event (other than with respect to Cutback Shares) not later than 75 days following the filing thereof (a “ Subsequent Effectiveness Deadline ”). For purposes of the foregoing provision, the number of shares available under a Registration Statement shall be deemed “insufficient to cover all of the Registrable Securities” if as of any date of determination, the number of shares of Common Stock available for resale under the Registration Statement is less than 100% of the sum of (x) the number of then-outstanding Conversion Shares and Warrant Shares that constitute Registrable Securities, (y) the number of Registrable Securities issuable upon conversion of then-outstanding Preferred Shares, and (z) the number of Registrable Securities issuable upon exercise of then-outstanding Warrants (e.g., because of an adjustment in the number of Conversion Shares issuable upon conversion of the Preferred Shares pursuant to Section 2(c) of the Certificate of Designations and in the number of Warrant Shares issuable upon exercise of the Warrants pursuant to Section 8 of the Warrants). The calculation set forth in the foregoing sentence shall be made without regard to any limitations on the conversion of the Preferred Shares or on the exercise of the Warrants.

i. If (A) a Registration Statement covering Registrable Securities and required to be filed by the Company pursuant to Section 2(a) , Section 2(b) or Section 2(f) of this Agreement is not (I) filed with the SEC on or before the applicable Filing Deadline (a “ Filing Failure ”) or (II) declared effective by the SEC on or before the applicable Effectiveness Deadline (an “ Effectiveness Failure ”) or (B) on any day after a Registration Statement has been declared effective by the SEC, sales of all the Registrable Securities required to be included on such Registration Statement cannot be made (other than during an Allowable Grace Period (as defined in Section 3(s) )) pursuant to such Registration Statement (including because of a failure to keep the such Registration Statement effective, to disclose such information as is necessary for sales to be made pursuant to such Registration Statement or to register sufficient shares of Common Stock, as determined in accordance with Section 2(f) ) (a “ Maintenance Failure ,” and each of a Filing Failure, an Effectiveness Failure and a Maintenance Failure being referred to as a “ Registration Default ”), then the Company shall pay, as partial liquidated damages (but not as a penalty) to any holder of Preferred Shares or Warrants by reason of any such delay in or reduction of its ability to sell the underlying shares of Common Stock (which remedy shall not be exclusive of any other remedies available at law or in equity), an amount in cash equal to one and one-half percent (1.5%) of the aggregate value of such holder’s Registrable Securities required to be included in such Registration Statement (such value being determined by multiplying the number of such Registrable Securities by the greater of (x) the then-current market price of such securities, and (y) $0.70) on each of the following dates: (1) the initial day of a Filing Failure and on every thirtieth (30 ^th ) day (prorated for periods totaling less than thirty (30) days) thereafter until such Filing Failure is cured; (2) the initial day of an Effectiveness Failure and on every thirtieth (30 ^th ) day (prorated for periods totaling less than thirty (30) days) thereafter until such Effectiveness Failure is cured; and (3) the initial day of a Maintenance Failure and on every thirtieth (30 ^th ) day (prorated for periods totaling less than thirty (30) days) thereafter until such Maintenance Failure is cured.

ii. The payments to which a holder shall be entitled pursuant to this Section 2(g) are referred to herein as “ Registration Delay Payments .” In the event the Company fails to make Registration Delay Payments in a timely manner, such Registration Delay Payments shall bear interest at the rate of the lesser of 1.5% per month (prorated for partial months) or the highest lawful interest rate, in each case, until paid in full.

At such time as the Company is obligated to file a Registration Statement with the SEC pursuant to Section 2(a) , Section 2(b) or Section 2(f) , the Company will use its best efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations:

a. The Company shall promptly prepare and file with the SEC a Registration Statement with respect to the applicable Registrable Securities (but in no event later than the applicable Filing Deadline) and use its best efforts to cause such Registration Statement relating to the Registrable Securities to become effective as soon as practicable after such filing (but in

- 7 -

no event later than the applicable Effectiveness Deadline). The Company shall use its reasonable best efforts to respond to written comments received from the SEC upon a review of a Registration Statement within ten Business Days. No later than the first Business Day after such Registration Statement becomes effective, the Company will file with the SEC the final prospectus included therein pursuant to Rule 424 (or successor thereto) promulgated under the 1933 Act. The Company shall keep each Registration Statement effective pursuant to Rule 415 at all times until the earlier of (i) the date as of which all of the Investors may sell all of the Registrable Securities covered by such Registration Statement pursuant to Rule 144 without limitation, restriction or condition (including any current public information requirement) thereunder, or (ii) the date on which the Investors have sold all of the Registrable Securities covered by such Registration Statement in accordance with such Registration Statement or pursuant to Rule 144 (the “ Registration Period ”). Such Registration Statement shall contain a “plan of distribution” approved by the holders of a majority of the Registrable Securities included therein. Such Registration Statement (including any amendments or supplements thereto and any prospectuses (preliminary, final, summary or free writing) contained therein or related thereto shall not contain any 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 in which they were made, not misleading. The term “best efforts” shall mean, among other things, that the Company shall submit to the SEC, within two Business Days after the Company learns that no review of a particular Registration Statement will be made by the staff of the SEC or that the staff of the SEC has no further comments on the Registration Statement, as the case may be, a request for acceleration of effectiveness of such Registration Statement to a time and date not later than two (2) Business Days after the submission of such request.

b. The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and the prospectus used in connection with such Registration Statement, as may be necessary to keep such Registration Statement effective at all times during the Registration Period, and, during such period, comply with the provisions of the 1933 Act with respect to the disposition of all Registrable Securities of the Company covered by such Registration Statement until such time as all of such Registrable Securities shall have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section   3(b) ) by reason of the Company filing a report on Form 10-Q, Form 10-K or any analogous report under the 1934 Act, the Company shall have incorporated such report by reference into such Registration Statement, if applicable, or shall file such amendments or supplements with the SEC within one Business Day after the 1934 Act report is filed which created the requirement for the Company to amend or supplement such Registration Statement. The Company shall promptly notify Legal Counsel and each Investor who holds Registrable Securities of any request by the SEC or any other Governmental Authority, during the period of effectiveness of a Registration Statement, for amendments or supplements to such Registration Statement or related prospectus or for additional information.

c. The Company shall (A) permit Legal Counsel to review and comment upon (i) the Initial Registration Statement at least three Business Days prior to its filing with the

- 8 -

SEC, and (ii) all other Registration Statements and all amendments and supplements to all Registration Statements (except for annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K, and any similar or successor reports) within a reasonable number of days prior to their filing with the SEC, and (B) not file any document, registration statement, amendment or supplement described in the foregoing clause (A) in a form to which Legal Counsel reasonably objects. The Company shall not submit a request for acceleration of the effectiveness of a Registration Statement or any amendment or supplement thereto without providing prior notice thereof to Legal Counsel and each Investor. The Company shall, upon request, furnish to Legal Counsel, without charge, (x) promptly after the same is prepared and filed with the SEC, one copy of any Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, and all exhibits, and (y) upon the effectiveness of any Registration Statement, one copy of the prospectus included in such Registration Statement and all amendments and supplements thereto. The Company shall promptly furnish to Legal Counsel, without charge, copies of any correspondence from the SEC to the Company or its representatives relating to any Registration Statement, shall permit Legal Counsel to review and comment upon the Company’s responses to any such correspondence and shall not submit any such responses in a form to which Legal Counsel reasonably objects. The Company shall reasonably cooperate with Legal Counsel in performing the Company’s obligations pursuant to this Section 3 .

d. The Company shall furnish to Legal Counsel and each Investor whose Registrable Securities are included in any Registration Statement, without charge, (i) promptly after the same is prepared and filed with the SEC, at least one copy of such Registration Statement and any amendment(s) thereto, including all documents incorporated therein by reference that have not been filed via EDGAR, (ii) upon the effectiveness of any Registration Statement, at least one copy of the prospectus included in such Registration Statement and all amendments thereto and (iii) such other documents, including copies of any prospectus or prospectus supplement (preliminary, final, summary or free writing), as such Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by such Investor; provided that the Company shall not be required to furnish to Legal Counsel or the Investors prospectus supplements that are filed with the SEC to forward incorporate by reference any report filed by the Company on Form 10-K, Form 10-Q or 8-K.

e. The Company shall use its best efforts to (i) register and qualify, unless an exemption from registration and qualification applies, the resale by the Investors of the Registrable Securities covered by a Registration Statement under the securities or “blue sky” laws of all applicable jurisdictions in the United States, (ii) prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions or obtain exemptions from the registration and qualification requirements of such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(e) , (y) subject itself to general taxation in any jurisdiction, or (z) file a general consent to service of process in any jurisdiction in which

- 9 -

it is not currently so qualified or subject to general taxation or has not currently so consented. The Company shall promptly notify Legal Counsel and each Investor who holds Registrable Securities of the receipt by the Company of any notification with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any jurisdiction in the United States or its receipt of actual notice of the initiation or threatening of any proceeding for such purpose.

f. The Company shall notify Legal Counsel and each Investor in writing of the happening of any event, as promptly as practicable after becoming aware of such event, as a result of which, in the case of a Registration Statement, it includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading and, in the case of the prospectus included in a Registration Statement, it includes an untrue statement of a material fact or omission 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 (provided that in each notice the Company shall not disclose any material non-public information to any Investor unless otherwise requested in writing by such Investor), and, subject to Section 3(s) , promptly prepare and file with the SEC a supplement or amendment to such Registration Statement to correct such untrue statement or omission, and deliver a copy of such supplement or amendment to Legal Counsel and each Investor (or such other number of copies as Legal Counsel or such Investor may reasonably request). The Company shall also promptly notify Legal Counsel and each Investor in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment has become effective (notification of such effectiveness shall be delivered to Legal Counsel and each Investor by facsimile on the same day of such effectiveness and by overnight mail), and (ii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate; provided that the Company shall not be required to notify Legal Counsel or any Investors of any prospectus supplements that are filed with the SEC to forward incorporate by reference any report filed by the Company on Form 10-K, Form 10-Q or 8-K.

g. The Company shall use its best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement (other than during an Allowable Grace Period, as defined below), or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible time and to notify Legal Counsel and each Investor who holds Registrable Securities being sold of the issuance of such order or suspension and the resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.

h. [Reserved].

i. At the reasonable request (in the context of applicable securities laws) of any Investor, the Company shall make available for inspection during regular business hours by (i) any Investor, (ii) Legal Counsel and (iii) one firm of accountants or other agents retained by the Investors (collectively, the “ Inspectors ”), all pertinent financial and other records, and pertinent corporate documents and properties of the Company (collectively, the “ Records ”), as shall be reasonably deemed necessary by each Inspector, and cause the Company’s officers,

- 10 -

directors and employees to supply all information which any Inspector may reasonably request; provided, however, that each Inspector shall agree to hold in strict confidence and shall not make any disclosure (except to an Investor) or use of any Record or other information which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless (a) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration Statement or is otherwise required under the 1933 Act, (b) the release of such Records is ordered pursuant to a subpoena or order from a court or government body of competent jurisdiction, or (c) the information in such Records has been made generally available to the public other than by disclosure in violation of this or any other agreement of which the Inspector has knowledge. Each Investor agrees that it shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the Records deemed confidential. Nothing herein (or in any other confidentiality agreement between the Company and any Investor) shall be deemed to limit the Investors’ ability to sell Registrable Securities in a manner that is otherwise consistent with applicable laws and regulations.

j. The Company shall hold in confidence and not make any disclosure of information concerning an Investor provided to the Company unless (i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or order from a court or governmental body of competent jurisdiction, or (iv) such information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Company agrees that it shall, upon learning that disclosure of such information concerning an Investor is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to such Investor and allow such Investor, at the Investor’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

k. The Company shall use its best efforts to (i) cause all the Registrable Securities covered by a Registration Statement to be listed on each securities exchange or trading market on which securities of the same class or series issued by the Company are listed, and (ii) without limiting the generality of the foregoing, arrange for at least one market maker to register with the Financial Industry Regulatory Authority (“ FINRA ”) as such with respect to such Registrable Securities. For the avoidance of doubt, the Company shall pay all fees and expenses in connection with satisfying its obligation under this Section 3(k) .

l. The Company shall cooperate with the Investors that hold Registrable Securities being offered and the underwriters, if any, and, to the extent applicable, facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Registration Statement and enable such certificates to be in such names and denominations or amounts, as the case may be, and/or the timely issuance of the Registrable Securities to be offered pursuant to a Registration Statement through the Direct Registration System (DRS) of The Depository Trust Company (the “ DTC ”) or crediting of the Registrable Securities to be offered pursuant to a Registration Statement to the applicable account (or accounts) with DTC through its Deposit/Withdrawal At Custodian (DWAC) system, in any such case as each Investor may reasonably request.

- 11 -

m. The Company shall provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of the applicable Registration Statement.

n. If requested by an Investor, the Company shall (i) as soon as practicable, incorporate in a prospectus supplement or post-effective amendment such information as such Investor requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to such Investor, the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) as soon as practicable, make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) as soon as practicable, supplement or amend any Registration Statement as reasonably requested by such Investor.

o. The Company shall make generally available to its security holders as soon as practical an earnings statement (in form complying with the provisions of Rule 158 under the 1933 Act) covering a 12-month period beginning not later than the first day of the Company’s fiscal quarter next following the effective date of a Registration Statement; provided that the parties acknowledge that the Company shall satisfy this section by timely filing its reports required pursuant to the 1934 Act.

p. The Company shall otherwise use its best efforts to comply with all applicable rules and regulations of the SEC in connection with any registration hereunder.

q. Within one Business Day after a Registration Statement which covers applicable Registrable Securities is declared effective by the SEC, the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable Securities (with copies to the Investors whose Registrable Securities are included in such Registration Statement) confirmation that such Registration Statement has been declared effective by the SEC in substantially the form attached hereto as Exhibit A , provided that if the Company changes its transfer agent, it shall immediately deliver any previously delivered notices under this Section 3(q) and any subsequent notices to such new transfer agent.

r. To the extent not made by the underwriters in the case of an underwritten offering, the Company shall make such filings with FINRA, pursuant to FINRA Rule 5110 or otherwise (including providing all required information and paying required fees thereto), as and when requested by any Investor, or in the case of an underwritten offering, by any underwriter, and make all other filings and take all other actions reasonably necessary to expedite and facilitate the disposition by the Investors of Registrable Securities pursuant to a Registration Statement, including promptly responding to any comments received from FINRA.

s. Notwithstanding anything to the contrary in Section 3(f) , at any time after the effective date of the applicable Registration Statement, the Company may delay the disclosure of material non-public information concerning the Company the disclosure of which

- 12 -

at the time is not, in the good faith opinion of the Board of Directors of the Company and its counsel, in the best interest of the Company and not, in the opinion of counsel to the Company, otherwise required (a “ Grace Period ”); provided, that the Company shall (i) promptly notify the Investors in writing of the existence of material non-public information giving rise to a Grace Period (provided that in each notice the Company shall not disclose the content of such material non-public information to any Investor unless otherwise requested in writing by such Investor) and the date on which the Grace Period will begin, and (ii) as soon as such date may be determined, promptly notify the Investors in writing of the date on which the Grace Period ends; and, provided , further , that (A) no Grace Period shall exceed thirty (30) consecutive days, (B) during any three hundred sixty five (365) day period, such Grace Periods shall not exceed an aggregate of sixty (60) days, and (C) the first day of any Grace Period must be at least ten (10) trading days after the last day of any prior Grace Period (each Grace Period that satisfies all of the requirements of this Section 3(s) being referred to as an “ Allowable Grace Period ”). For purposes of determining the length of a Grace Period above, the Grace Period shall begin on and include the date the Investors receive the notice referred to in clause (i) and shall end on and include the later of the date the Investors receive the notice referred to in clause (ii) and the date referred to in such notice. The provisions of Section 3(f) hereof shall not be applicable during the period of any Allowable Grace Period. Upon expiration of the Grace Period, the Company shall again be bound by the first sentence of Section 3(f) with respect to the information giving rise thereto unless such material non-public information is no longer applicable.

t. The Company shall enter into such customary agreements (including, in the case of underwritten offering, an underwriting agreement) and take such other actions as any of the Investors or underwriters, if any, may reasonably request in order to expedite and facilitate the disposition of the Registrable Securities covered by a Registration Statement.

a. At least ten Business Days prior to the first anticipated filing date of a Registration Statement and at least seven Business Days prior to the filing of any amendment or supplement to a Registration Statement, the Company shall notify each Investor in writing of the information, if any, the Company requires from each such Investor if such Investor elects to have any of such Investor’s Registrable Securities included in such Registration Statement or, with respect to an amendment or a supplement, if such Investor’s Registrable Securities are included in such Registration Statement (each an “ Information Request ”). Provided that the Company shall have complied with its obligations set forth in the preceding sentence, it shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the Registrable Securities of a particular Investor that such Investor shall furnish to the Company, in response to an Information Request, such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required to effect the registration of such Registrable Securities.

b. Each Investor, by such Investor’s acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any Registration Statement hereunder, unless such Investor has notified the Company in writing of such Investor’s election to exclude all of such Investor’s Registrable Securities from such Registration Statement.

- 13 -

c. Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(g) or the first sentence of Section 3(f) , or written notice from the Company of an Allowable Grace Period, such Investor will discontinue disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable Securities until such Investor’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(g) or the first sentence of Section 3(f) or receipt of notice from the Company in writing that no supplement or amendment is required or that the Allowable Grace Period has ended. Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of an Investor in accordance with the terms of the Certificate of Designations in connection with any sale of Registrable Securities with respect to which an Investor has entered into a contract for sale prior to the Investor’s receipt of a notice from the Company of the happening of any event of the kind described in Section 3(g) or the first sentence of Section 3(f) and for which the Investor has not yet settled.

All expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant to Sections 2 and 3 , including all registration, listing and qualifications fees, printers and accounting fees, and fees and disbursements of counsel for the Company, as well as all other costs and expenses incurred in connection with the Company’s compliance with its obligations under this Agreement, shall be paid by the Company. The Company shall also reimburse the Investors for the reasonable fees and disbursements of Legal Counsel of up to $10,000 per registration in connection with registration, filing or qualification pursuant to Sections 2 and 3 of this Agreement.

In the event any Registrable Securities are included in a Registration Statement:

a. To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Investor, the directors, officers, partners, members, managers, investment managers, employees, affiliates, agents and representatives of, and each Person, if any, who controls any Investor within the meaning of the 1933 Act or the 1934 Act (each, an “ Indemnified Person ”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement, joint or several, and any expenses (collectively, “ Indemnified Damages ”), incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or Governmental Authority or other administrative or regulatory agency or body (including the SEC and any state commission or authority or self-regulatory organization or securities exchange in the United States or elsewhere), whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“ Claims ”), to which any of them may become subject insofar as such Claim (or actions or proceedings, whether commenced or threatened, in respect thereof) or Indemnified Damages

- 14 -

arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment thereto or in any filing made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered, or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements made therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any prospectus, including any preliminary prospectus, free writing prospectus or final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto, and including all information incorporated by reference therein), or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading, (iii) any violation or alleged violation by the Company of the 1933 Act, the 1934 Act, any other law, including any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to a Registration Statement or (iv) any breach or violation of this Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively, “ Violations ”). Subject to Section 6(c) , the Company shall reimburse the Indemnified Persons, promptly as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a) : (x) shall not apply to a Claim or Indemnified Damages sought by an Indemnified Person to the extent arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto; and (y) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive any transfer of Registrable Securities by any Investor pursuant to Section 9 .

b. In connection with any Registration Statement in which an Investor’s Registrable Securities are included, each such Investor agrees to severally and not jointly indemnify, hold harmless and defend the Company, each of its directors, each of its officers who signs the Registration Statement, and each Person, if any, who controls the Company within the meaning of the 1933 Act or the 1934 Act (each an “ Indemnified Party ”), to the same extent and in the same manner as is set forth in Section 6(a) with respect to the Indemnified Persons, against any Claim or Indemnified Damages to which any of them may become subject insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with the preparation of the Registration Statement or any amendment thereof or supplement thereto; and, subject to Section 6(c) , such Investor will reimburse any legal or other expenses reasonably incurred by an Indemnified Party in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall not apply to amounts paid in settlement of any Claim or Indemnified Damages if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably withheld; provided,

- 15 -

further, that an Investor shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds to such Investor as a result of the sale of Registrable Securities pursuant to the Registration Statement giving rise to such indemnification obligation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive any transfer of Registrable Securities by any Investor pursuant to Section 9 .

c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of the written threat of or notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim or Indemnified Damages, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6 , promptly deliver to the indemnifying party a written notice of the written threat of or notice of the commencement of such action or proceeding. In case any such action or proceeding is brought against any Indemnified Party or Indemnified Person and such Indemnified Party or Indemnified Person seeks or intends to seek indemnity from an indemnifying party, the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be. In any such proceeding, any Indemnified Person or Indemnified Party may retain its own counsel, but the fees and expenses of that counsel will be at the expense of that Indemnified Person or Indemnified Party, as the case may be, unless (i) the indemnifying party and the Indemnified Person or Indemnified Party, as applicable, shall have mutually agreed to the retention of that counsel, (ii) the indemnifying party does not assume the defense of such proceeding in a timely manner or (iii) in the opinion of counsel retained by the Indemnified Person or Indemnified Party, as applicable, the representation by such counsel for the Indemnified Person or Indemnified Party, as applicable, and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by counsel to the indemnifying party in such proceeding. The Indemnified Party or Indemnified Person shall reasonably cooperate with the indemnifying party in connection with any negotiation or defense of any such action or proceeding or Claim or Indemnified Damages by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action, proceeding or Claim or Indemnified Damages. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall, without the prior written consent of the Indemnified Party or Indemnified Person, as the case may be, consent to entry of any judgment or enter into any settlement or other compromise with respect to any pending or threatened action or claim in respect of which indemnification or contribution may be or has been sought hereunder (whether or not the Indemnified Party or Indemnified Person is an actual or potential party to such action or claim) which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person (as applicable) of a full release from all liability with respect to such Claim or Indemnified Damages or which includes any admission as to fault or culpability on the part of such Indemnified Party or Indemnified Person. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action or proceeding shall not relieve such indemnifying party of

- 16 -

any liability to the Indemnified Person or Indemnified Party under this Section 6 , except to the extent that the indemnifying party is materially prejudiced in its ability to defend such action or proceeding as a result of such failure.

d. The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred.

e. The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.

To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities which Person is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) in connection with such sale shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities pursuant to such Registration Statement, less the amount of any damages that such Investor has otherwise been required to pay in connection with such sale.

a. With a view to making available to the Investors the benefits of Rule 144, the Company agrees to:

i. make and keep public information available, as those terms are understood and defined in Rule 144;

ii. file with the SEC in a timely manner all reports and other documents required of the Company under the 1934 Act so long as the Company remains subject to such requirements (it being understood that nothing herein shall limit the Company’s obligations under Section 4(c) of the Securities Purchase Agreement) and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

iii. furnish to each Investor so long as such Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144 and the 1934 Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Investors to sell such securities pursuant to Rule 144 without registration.

b. For so long as the Principal Market is not a National Exchange (as such terms are defined in the Securities Purchase Agreement), the Company shall use its reasonable best efforts to facilitate trading of the Common Stock on the Principal Market and, without limiting the foregoing, the Company shall file all necessary reports, at its expense, to publish all information so as to have available “current public information” in Standard & Poor’s Corporation Records or Mergent’s Manual for state “blue sky” exemption purposes.

The rights under this Agreement shall be automatically assignable by the Investors to any transferee of all or any portion of Registrable Securities if: (i) the Investor agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company; (ii) the Company is furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights are being transferred or assigned; (iii) immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the 1933 Act and applicable state securities laws; and (iv) the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein.

Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the Required Holders. Any amendment or waiver effected in accordance with this Section   10 shall be binding upon each Investor and the Company. No such amendment shall be effective to the extent that it applies to less than all of the holders of the Registrable Securities. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of this Agreement unless the same consideration also is offered to each of the Investors.

a. A Person is deemed to be a holder of Registrable Securities (or a transferee or assignee of Registrable Securities, as applicable) whenever such Person owns or is deemed to own of record such Registrable Securities (or the Preferred Shares or the Warrants or other securities upon exercise, conversion or exchange of which such Registrable Securities are directly or indirectly issuable, without giving effect to any limitations or restrictions on conversion of the Preferred Shares or other securities). If the Company receives conflicting instructions, notices or elections from two or more Persons with respect to the same Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the registered owner of such Registrable Securities (or the Preferred Shares or the Warrants or other securities upon exercise, conversion or exchange of which such Registrable Securities are directly or indirectly issuable).

c. Failure of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in exercising such right or remedy, shall not operate as a waiver thereof.

d. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. Each party hereby irrevocably submits to the exclusive jurisdiction of the Chancery Court of the State of Delaware and any state appellate court therefrom sitting in New Castle County in the State of Delaware (or, if the Chancery Court of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

e. This Agreement and the other Transaction Documents and the Certificate of Designations constitute the entire agreement among the parties hereto with respect to the subject matter hereof and thereof. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein and therein. This Agreement and the other Transaction Documents and the Certificate of Designations supersede all prior agreements and understandings among the parties hereto with respect to the subject matter hereof and thereof.

g. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

h. This Agreement and any amendments hereto may be executed and delivered in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement, and shall become effective when counterparts have been signed by each party hereto and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. In the event that any signature to this Agreement or any amendment hereto is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. No party hereto shall raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that such signature was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation or enforceability of a contract and each party hereto forever waives any such defense.

i. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

j. All consents and other determinations to be made by the Investors pursuant to this Agreement shall be made, unless otherwise specified in this Agreement, by the Required Holders, for Registrable Securities without regard to any limitations on the conversion of the Preferred Shares or on the exercise of the Warrants. Any consent or other determination approved by Investors as provided in the immediately preceding sentence shall be binding on all Investors.

l. Each Buyer and each holder of the Registrable Securities shall have all rights and remedies set forth in the Transaction Documents and the Certificate of Designations and all rights and remedies that such Buyers and holders have been granted at any time under any other agreement or contract and all of the rights that such Buyers and holders have under any law. Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security or proving actual damages), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law.

- 21 -

m. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns and, to the extent provided in Sections 6 and 7 hereof, each Indemnified Person and Indemnified Party, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

n. The Company shall not grant any Person any registration rights with respect to shares of Common Stock or any other securities of the Company other than registration rights that will not adversely affect the rights of the Investors hereunder (including by limiting in any way the number of Registrable Securities that could be included in any Registration Statement pursuant to Rule 415) and shall not otherwise enter into any agreement that is inconsistent with the rights granted to the Investors hereunder.

o. The obligations of each Investor hereunder are several and not joint with the obligations of any other Investor, and no provision of this Agreement is intended to confer any obligations on any Investor vis-à-vis any other Investor. Nothing contained herein, and no action taken by any Investor pursuant hereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated herein.

p. Unless the context otherwise requires, (a) all references to Sections, Schedules or Exhibits are to Sections, Schedules or Exhibits contained in or attached to this Agreement, (b) each accounting term not otherwise defined in this Agreement or the Securities Purchase Agreement has the meaning assigned to it in accordance with GAAP, (c) words in the singular or plural include the singular and plural, and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter and (d) the use of the word “including” in this Agreement shall be by way of example rather than limitation.

FORM OF NOTICE OF EFFECTIVENESS

OF REGISTRATION STATEMENT

[TRANSFER AGENT]

Attn:

Ladies and Gentlemen:

We are counsel to Stereotaxis, Inc., a Delaware corporation (the “ Company ”), and have represented the Company in connection with that certain Securities Purchase Agreement (the “ Purchase Agreement ”) entered into by and among the Company and the buyers named therein (collectively, the “ Holders ”) pursuant to which the Company issued to the Holders (1) 24,000 shares (the “ Preferred Shares ”) of the Company’s Series A Convertible Preferred Stock, with a stated value of $1,000 per share (“ Preferred Stock ”), which are convertible into shares (the “ Conversion Shares ”) of the Company’s common stock, $0.001 par value per share (“ Common Stock ”), subject to adjustment, and (2) Warrants (the “ Warrants ”) to purchase an aggregate of 36,923,077 shares (the “ Warrant Shares ”) of Common Stock, subject to adjustment, as set forth in, and subject to the terms and conditions of, the Purchase Agreement. Pursuant to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement with the Holders (the “ Registration Rights Agreement ”) pursuant to which the Company agreed, among other things, to register the Registrable Securities (as defined in the Registration Rights Agreement), including the Conversion Shares and the Warrant Shares, under the Securities Act of 1933, as amended (the “ 1933 Act ”). In connection with the Company’s obligations under the Registration Rights Agreement, on                  , 200  , the Company filed a Registration Statement on Form [S-    ] (File No. 333-            ) (the “ Registration Statement ”) with the Securities and Exchange Commission (the “ SEC ”) relating to              Registrable Securities which names each of the Holders as a selling stockholder thereunder.

In connection with the foregoing, we advise you that the SEC has entered an order declaring the Registration Statement effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and the Registrable Securities covered thereby are available for resale under the 1933 Act pursuant to the Registration Statement.
