REGISTRATION RIGHTS AGREEMENT

REGISTRATION RIGHTS AGREEMENT (this “Agreement”), dated as of January 5, 2007, is by and between ENER1, INC., a Florida corporation (the “Company”), and CREDIT SUISSE SECURITIES (USA), LLC (the “Purchaser”).

The Purchaser has agreed, on the terms and subject to the conditions set forth in a Purchase Agreement, dated as of January 5, 2007, to which the Company and the Purchaser are parties (the “Purchase Agreement”), to purchase (i) shares (the “Purchased Shares”) of the Company’s Common Stock, par value $0.01 per share (the “Common Stock”), and (ii) a Warrant in the form attached to the Purchase Agreement (the “Warrant”) exercisable for shares of Common Stock (the “Warrant Shares”).

In order to induce the Purchaser to enter into the Purchase Agreement, the Company has agreed to provide certain registration rights under the Securities Act of 1933, as amended (the “Securities Act”), and under applicable state securities laws. Capitalized terms used herein and not otherwise defined shall have the respective meanings set forth in the Purchase Agreement.

In consideration of the Purchaser entering into the Purchase Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1. DEFINITIONS.

For purposes of this Agreement, the following terms shall have the meanings specified:

(a) “Filing Deadline” means the forty-fifth (45^th) calendar day following the Closing Date;

(b) “Holder” means any Person owning or having the right to acquire, including without limitation through exercise of the Warrants, Registrable Securities, including initially the Purchaser and thereafter any assignee permitted hereunder;

(c) “Outstanding Registrable Securities” means, at any time, all Registrable Securities that at such time are either issued and outstanding or issuable upon exercise of the Warrants (without regard to any limitation on such exercise);

(d) “Principal Market” means the principal exchange or market on which the Common Stock is listed or traded.

(e) “Registrable Securities” means the Purchased Shares and the Warrant Shares and any other shares of Common Stock issuable pursuant to the exercise of the Warrant, and any shares of capital stock or rights to purchase capital stock issued or issuable from time to time (with any adjustments) in replacement of, in exchange for or otherwise in respect of the Purchased Shares or the Warrant Shares; provided, however, that “Registrable Securities” shall not include any such shares of Common Stock that have been sold to the public pursuant to the Registration Statement or Rule 144;

(f) “Registration Deadline” means the earlier of (i) the ninetieth (90^th) calendar day following the Closing Date or, if the Registration Statement is subject to a full review by the Commission, the one hundred and twentieth (120^th) calendar day following the Closing Date and (ii) the fifth (5^th) Business Day after the Company learns that no review of the Registration Statement will be made by the staff of the Commission or that the staff of the Commission has no further comments on the Registration Statement (or such later date as the Commission may require following the submission by the Company of a request for acceleration of the effectiveness of the Registration Statement);

(g) “Registration Period” means the period beginning on the Registration Deadline (or such earlier date on which the Registration Statement may have been declared effective by the Commission) and ending on the earlier to occur of (A) the date on which all Registrable Securities have been sold under the Registration Statement or Rule 144 and (B) the date on which any Registrable Securities (in the reasonable opinion of counsel to the Company or any Holder) may be sold to the public under Rule 144(k) or any successor provision by a Person that is not an Affiliate of the Company at the time of such sale or during the period of ninety (90) days prior thereto; and

(h) “Registration Statement” means the Registration Statement(s) to be filed hereunder relating to resales of the Registrable Securities.

(i) “Trading Day” means any day on which the Common Stock is purchased and sold on the Principal Market.

(j) “Trading Price” means, as of any date, the arithmetical average of the VWAP during the ten (10) Trading Days immediately preceding (but not including) such date.

(k) “VWAP” on a Trading Day means the volume weighted average price of the Common Stock for such Trading Day on the Principal Market as reported by Bloomberg Financial Markets or, if Bloomberg Financial Markets is not then reporting such prices, by a comparable reporting service of national reputation selected by the Company and reasonably satisfactory to the Holders of at least a majority of the number of Outstanding Registrable Securities. If the VWAP cannot be calculated for the Common Stock on such Trading Day on any of the foregoing bases, then the Company shall submit such calculation to an independent investment banking firm of national reputation, and shall cause such investment banking firm to perform such determination and notify the Company of the results of determination no later than two (2) Business Days from the time such calculation was submitted to it by the Company. All such determinations shall be appropriately adjusted for any stock dividend, stock split or other similar transaction during such period.

2. REGISTRATION.

(a) Registration Statement. On or before the Filing Deadline, the Company shall use its reasonable best efforts to prepare and file with the Commission the Registration Statement on Form SB-2 as a “shelf” registration statement under Rule 415 under the Securities Act (“Rule 415”) covering the resale of a number of shares of Common Stock equal to or greater than the sum of (i) the number of shares required to be reserved pursuant to the Purchase Agreement as of the Closing Date and (ii) the number of Purchased Shares. The Registration Statement shall state, to the extent permitted by Rule 416 under the Securities Act, that it also covers such indeterminate number of additional shares of Common Stock in order to prevent dilution resulting from stock splits, stock dividends or similar events. In the event that the Company becomes eligible to file a registration statement on Form S-3 (but in no event later than the thirtieth (30^th) day after the date on which the Company becomes so eligible), it shall convert the Registration Statement to a Form S-3, or file a new registration statement on such form, covering the greater of (i) the number of shares of Common Stock covered by the Registration Statement and remaining unsold thereunder and (ii) the number of Outstanding Registrable Securities.

(b) Effectiveness. The Company shall use its reasonable best efforts to cause the Registration Statement to become effective as soon as practicable following the filing thereof, but in no event later than the Registration Deadline. The Company shall respond reasonably promptly to any and all comments made by the staff of the Commission on the Registration Statement, and shall promptly submit to the Commission, within three (3) Business Days after the Company learns that no review of the Registration Statement will be made by the staff of the Commission or that the staff of the Commission has no further comments on the Registration Statement, as the case may be, a request for acceleration of the effectiveness of the Registration Statement to a time and date not later than two (2) Business Days following the submission of such request. The Company shall use its reasonable best efforts to maintain the effectiveness of the Registration Statement and the availability of a prospectus for sales of Registrable Securities during the Registration Period.

(c) Registration Default. If (A) the Registration Statement is not filed in the form required hereby on or before the applicable Filing Deadline or declared effective by the Commission on or before the Registration Deadline, or (B) after the Registration Statement has been declared effective by the Commission and other than during a period in which an Allowed Delay (as hereinafter defined) is in effect, sales of Registrable Securities cannot be made by a Holder under the Registration Statement for any reason not within the exclusive control of such Holder, (each of (A) and (B) being referred to herein as a “Registration Default”), the Company shall make payments to each Holder (each, a “Registration Default Payment”) equal to one percent (1.0%) of the Purchase Price for the Securities then held by such Holder for each thirty (30) day period until the Registration Default is cured (such payment to be prorated for any period in which the Registration Default continues for less than thirty days). Each Registration Default Payment may, at the Company’s option, be paid in cash in immediately available funds or in shares of its Common Stock; provided that if a Registration Default Payment is made in shares of Common Stock, the number of shares issuable as payment shall be equal to the quotient obtained by dividing (i) the amount of such Registration Default Payment by (ii) 97% of the Trading Price as of the last day of the calendar month in which the Registration Default giving rise to such Registration Default Payment occurred or is continuing. Each Registration Default Payment shall be made within five (5) Business Days following the last day of the calendar month in which the Registration Default giving rise to such Registration Default Payment occurred or is continuing. Any such payment shall be in addition to any other remedies available to each Holder at law or in equity, whether pursuant to the terms hereof, the Purchase Agreement, or otherwise.

(d) Allowed Delay. The Company may delay the disclosure of material non-public information, and suspend the availability of the Registration Statement, for a period not to exceed (i) fifteen (15) consecutive Business Days at any one time (each such fifteen Business Day period to be separated by at least ten (10) Business Days from the next such period) or (ii) sixty (60) calendar days in any twelve (12) month period; provided, however, that the Company may delay such disclosure only in the event of a proposed merger, reorganization or similar transaction involving the Company where its board of directors (A) has determined, upon the advice of counsel, that such information would be required to be disclosed in an offering registered under the Securities Act and (B) reasonably deems it in the best interests of the Company and its shareholders not to disclose such information publicly (an “Allowed Delay”). The Company shall (i) promptly notify each Holder in writing of the existence of information giving rise to an Allowed Delay (but in no event, without the prior written consent of such Holder, shall the Company disclose to such Holder any material non-public information), (ii) promptly advise each Holder in writing to cease all sales under the Registration Statement until the termination of the Allowed Delay and (iii) promptly notify each Holder in writing immediately upon the termination or expiration of an Allowed Delay.

(e) Allocation. If at any time there is more than one Holder, the number of Registrable Shares then included in any Registration Statement and each increase in the number thereof included therein shall be allocated pro rata among the Holders based on the aggregate number of Outstanding Registrable Securities held by each Holder at the time the Registration Statement covering such initial number of Registrable Securities or increase thereof is declared effective by the Commission (without regard to any restriction on the ability of a Holder to exercise such Holder’s Warrants as of such date). In the event that a Holder sells or otherwise transfers any of such Holder’s Registrable Securities, each transferee shall be allocated the portion of the then remaining number of Registrable Securities included in the Registration Statement allocable to the transferor. Any portion of the Registrable Securities included in the Registration Statement and allocated to a Holder or other Person which no longer holds any Registrable Securities shall be reallocated to the remaining Holders pro rata based on the number of Outstanding Registrable Securities.

3. PIGGYBACK REGISTRATION.

If at any time prior to the expiration of the Registration Period, (i) the Company proposes to register shares of Common Stock under the Securities Act in connection with the public offering of such shares for cash (a “Proposed Registration”) other than a registration statement on Form S-8 or Form S-4 or any successor or other forms promulgated for similar purposes and (ii) the Registration Statement covering the sale of all of the Registrable Securities is not then effective and available for sales thereof by the Holders, the Company shall, at such time, promptly give each Holder written notice of such Proposed Registration. Each Holder shall have ten (10) Business Days from its receipt of such notice to deliver to the Company a written request specifying the amount of Registrable Securities that such Holder intends to sell and such Holder’s intended method of distribution. Upon receipt of such request, the Company shall use its commercially reasonable efforts to cause all Registrable Securities which the Company has been requested to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of such Holder; provided, however, that the Company shall have the right to postpone or withdraw any registration effected pursuant to this Section 3 without obligation to the Holder. If, in connection with any underwritten public offering for the account of the Company or for stockholders of the Company that have contractual rights to require the Company to register shares of Common Stock, the managing underwriter(s) thereof shall impose a limitation on the number of shares of Common Stock which may be included in the registration statement because, in the judgment of such underwriter(s), marketing or other factors dictate such limitation is necessary to facilitate such offering, then the Company shall be obligated to include in the registration statement only such limited portion of the Registrable Securities with respect to which each Holder has requested inclusion hereunder as such underwriter(s) shall permit. Any exclusion of Registrable Securities shall be made pro rata among the Holders seeking to include Registrable Securities in the registration statement, in proportion to the number of Registrable Securities sought to be included by such Holders; provided, however, that the Company shall not exclude any Registrable Securities unless the Company has first excluded all outstanding securities, the holders of which are not entitled to inclusion of such securities in the registration statement or are not entitled to pro rata inclusion with the Registrable Securities; and providedfurther, that, after giving effect to the immediately preceding proviso, any exclusion of Registrable Securities shall be made pro rata with holders of other securities having the right to include such securities in the registration statement.

4.OBLIGATIONS OF THE COMPANY.

In addition to its obligations specified elsewhere in this Agreement, the Company shall:

(a) prepare and file with the Commission such amendments and supplements to the Registration Statement and the prospectus used in connection with the Registration Statement as may be necessary to comply with the provisions of the Securities Act or to maintain the effectiveness of the Registration Statement during the Registration Period (subject to any Allowed Delays), or as may be reasonably requested by a Holder in order to incorporate information concerning such Holder or such Holder’s intended method of distribution;

(b) use commercially reasonable efforts to secure the listing of all Registrable Securities on the Principal Market, and provide each Holder with reasonable evidence thereof;

(c) upon the effectiveness of the Registration Statement, furnish to each Holder such number of copies of the prospectus included in the Registration Statement, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Holder may reasonably request in order to facilitate the disposition of such Holder’s Registrable Securities;

(d) use all commercially reasonable efforts to register or qualify the Registrable Securities under the securities or “blue sky” laws of such jurisdictions within the United States as shall be reasonably requested in writing from time to time by a Holder, and do any and all other acts or things which may be necessary or advisable to enable such Holder to consummate the public sale or other disposition of the Registrable Securities in such jurisdictions; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such jurisdiction;

(e) in the event of an underwritten public offering of the Registrable Securities, enter into (together with all Holders proposing to distribute Registrable Securities through such underwriting) and perform its obligations under an underwriting agreement, in usual and customary form reasonably acceptable to the Company, with the managing underwriter of such offering;

(f) notify each Holder immediately after becoming aware of the occurrence of any event (but shall not, without the prior written consent of such Holder, disclose to such Holder any facts or circumstances constituting material non-public information) as a result of which the prospectus included in the Registration Statement, as then in effect, contains an untrue statement of material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and (except during an Allowed Delay) as promptly as practicable prepare, and file with the Commission and furnish to each Holder a reasonable number of copies of a supplement or an amendment to such prospectus as may be necessary so that such prospectus does not contain an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing;

(g) use all commercially reasonable efforts to prevent the issuance of any stop order or other order suspending the effectiveness of the Registration Statement and, if such an order is issued, to obtain the withdrawal thereof at the earliest possible time and to notify each Holder of the issuance of such order and the resolution thereof;

(h) furnish to each Holder, within two (2) Business Days following the date on which the Registration Statement, or any successor registration statement, becomes effective, (x) a letter, dated such date, from the Company addressed to such Holder, confirming such effectiveness and, to the knowledge of the Company, the absence of any stop order, and (y) in the case of an underwriting, (A) a copy of an opinion, dated such date, of outside counsel to the Company, in such form and substance as is required to be given to the underwriters, and (B) a copy of a letter, dated such date, from the Company’s independent certified public accountants, in such form and substance as is required to be given by the Company’s independent certified public accountants to such underwriters;

(i) during the Registration Period or at any other time when the Registration Statement is effective and available to the Holders for the resale of Registrable Securities, provide to each Holder and its representatives, upon reasonable prior notice and execution of a reasonable non-disclosure agreement by such Holder (provided that such non-disclosure agreement shall permit disclosure of material information if required in connection with an underwriting or other distribution of the Registrable Securities), the opportunity to conduct a reasonable inquiry of the Company’s financial and other records during normal business hours and make available its officers for questions regarding information which such Holder may reasonably request in order to fulfill any due diligence obligation on its part; and

(j) permit counsel for each Holder to review the Registration Statement and all amendments and supplements thereto, and any comments made by the staff of the Commission concerning such Holder and/or the transactions contemplated by the Transaction Documents and the Company’s responses thereto, within a reasonable period of time (but in no event less than three (3) Business Days after such Holder has received such documents) prior to the filing thereof with the Commission (or, in the case of comments made by the staff of the Commission, within a reasonable period of time following the receipt thereof by the Company).

5. OBLIGATIONS OF EACH HOLDER.

In connection with the registration of Registrable Securities pursuant to the Registration Statement, each Holder shall:

(a) timely furnish to the Company in writing such information regarding itself and the intended method of disposition of such Registrable Securities as the Company shall reasonably request in order to effect the registration thereof;

(b) upon receipt of any notice from the Company of the happening of any event of the kind described in paragraphs 4(f) or 4(g), immediately discontinue any sale or other disposition of such Registrable Securities pursuant to the Registration Statement until the filing of an amendment or supplement as described in paragraph 4(f) or withdrawal of the stop order referred to in paragraph 4(g), and, if such Holder has agreed in writing to receive material, non-public information, to use commercially reasonable efforts to maintain the confidentiality of such notice and its contents;

(c) in the event of an underwritten offering of such Registrable Securities in which such Holder participates pursuant to Section 3 hereof, enter into a customary and reasonable underwriting agreement and execute such other documents (including without limitation “lock-up” and indemnity agreements) as the Company and the managing underwriter for such offering may reasonably request;

(d) to the extent required by applicable law, deliver a preliminary prospectus to the purchaser of Registrable Securities sold under the Registration Statement;

(e) notify the Company when it has completed the sale of all of the Registrable Securities held by it;

(f) notify the Company promptly in the event that any information supplied by such Holder in writing for inclusion in the Registration Statement or related prospectus is untrue or omits to state a material fact required to be stated therein or necessary to make such information not misleading in light of the circumstances then existing; immediately discontinue any sale or other disposition of such Registrable Securities pursuant to the Registration Statement until the filing of an amendment or supplement to such prospectus as may be necessary so that such prospectus does not contain an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; and provide the Company with updates on such information as may be appropriate to make such amendment or supplement effective for such purpose; and

(g) otherwise use commercially reasonable efforts to assist the Company and the underwriters, if any, in the preparation of documentation reasonably necessary or desirable to effectuate the resale of Registrable Securities pursuant to any Registration Statement filed in accordance herewith.

6. INDEMNIFICATION.

In the event that any Registrable Securities are included in the Registration Statement under this Agreement:

(a) The Company shall indemnify and hold harmless each Holder, the officers, directors, employees, agents and representatives of such Holder, and each person, if any, who controls such Holder within the meaning of the Securities Act or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), against any losses, claims, damages, liabilities or reasonable out-of-pocket expenses (whether joint or several) (collectively, including legal or other expenses reasonably incurred in connection with investigating or defending same, “Losses”), insofar as any such Losses arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Subject to the provisions of paragraph 6(c) below, the Company will reimburse such Holder, and each such officer, director, employee, agent, representative or controlling person, for any legal or other out-of-pocket expenses as reasonably incurred by any such entity or person in connection with investigating or defending any Loss; provided, however, that the foregoing indemnity shall not apply to amounts paid in settlement of any Loss if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be obligated to indemnify any person for any Loss to the extent that such Loss is based upon and is in conformity with written information furnished by such person expressly for use in the Registration Statement.

(b) Each Holder who is named in the Registration Statement as a selling stockholder, acting severally and not jointly, shall indemnify and hold harmless the Company, the officers, directors, employees, agents and representatives of the Company, and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any Losses arising out of (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, to the extent (and only to the extent) that any such statement or omission is made in reliance on and in conformity with written information concerning such Holder furnished by such Holder expressly for use in the Registration Statement. Subject to the provisions of paragraph 6(c) below, such Holder will reimburse any legal or other expenses as reasonably incurred by the Company and any such officer, director, employee, agent, representative, or controlling person, in connection with investigating or defending any such Loss; provided, however, that the foregoing indemnity shall not apply to amounts paid in settlement of any such Loss if such settlement is effected without the consent of such Holder (which consent shall not be unreasonably withheld); and provided, further, that, in no event shall any indemnity under this subsection 6(b) exceed the net proceeds resulting from the sale of the Registrable Securities sold by such Holder under the Registration Statement.

(c) Promptly after receipt by an indemnified party under this Section 6 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the reasonably incurred fees and expenses of one such counsel for all indemnified parties to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate under applicable standards of professional conduct due to actual or potential conflicting interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, to the extent prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 6 with respect to such action, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 6 or with respect to any other action unless the indemnifying party is materially prejudiced as a result of not receiving such notice.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 6 is unavailable or insufficient to hold harmless an indemnified party for any reason, the Company and each Holder agree, severally and not jointly, to contribute to the aggregate Losses to which the Company or such Holder may be subject in such proportion as is appropriate to reflect the relative fault of the Company and such Holder in connection with the statements or omissions which resulted in such Losses; provided, however, that in no case shall such Holder be responsible for any amount in excess of the net proceeds resulting from the sale of the Registrable Securities sold by it under the Registration Statement. Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the Company or by such Holder. The Company and each Holder agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each person who controls a Holder within the meaning of either the Securities Act or the Exchange Act and each officer, director, employee, agent or representative of such Holder shall have the same rights to contribution as such Holder, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act and each officer, director, employee, agent or representative of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in an underwriting agreement entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

(f) Unless otherwise superceded by an underwriting agreement entered into in connection with an underwritten public offering, the obligations of the Company and each Holder under this Section 6 shall survive the exercise of the Warrants in full, the completion of any offering or sale of Registrable Securities pursuant to the Registration Statement under this Agreement, or otherwise.

7. REPORTS.

For such time as any Registrable Securities are outstanding, with a view to making available to each Holder the benefits of Rule 144 under the Securities Act (“Rule 144”) and any other similar rule or regulation of the Commission that may at any time permit such Holder to sell securities of the Company to the public without registration, the Company agrees to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144;

(b) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act;

(c) furnish to such Holder, so long as such Holder owns any Registrable Securities, promptly upon written request (i) a written statement by the Company, if true, that it has complied with the reporting requirements to enable such Holder to rely on Rule 144(c), and that it has also complied with the reporting requirements of the Securities Act and the Exchange Act, (ii) to the extent not publicly available through the Commission’s EDGAR database, 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 by such Holder in connection with such Holder’s compliance with any rule or regulation of the Commission which permits the selling of any such securities without registration; and

(d) not at any time disclose material non-public information to such Holder without first receiving such Holder’s written consent to such disclosure.

8. MISCELLANEOUS.

(a) Expenses of Registration. Except as otherwise provided in the Purchase Agreement, all reasonable expenses, other than underwriting discounts and commissions and fees and expenses of counsel and other advisors to each Holder, incurred in connection with the registrations, filings or qualifications described herein, including (without limitation) all registration, filing and qualification fees, printers’ and accounting fees, the fees and disbursements of counsel for the Company, and the fees and disbursements incurred in connection with the opinion and letter described in paragraph 4(h) hereof, shall be borne by the Company.

(b) Amendment; Waiver. Except as expressly provided herein, neither this Agreement nor any term hereof may be amended or waived except pursuant to a written instrument executed by the Company and the Holders of at least two-thirds (2/3) of the number of Outstanding Registrable Securities. Any amendment or waiver effected in accordance with this paragraph shall be binding upon each Holder, each future Holder and the Company, provided, however, that any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

(c) Notices. Any notice, demand or request required or permitted to be given by the Company or an Purchaser pursuant to the terms of this Agreement shall be in writing and shall be deemed delivered (i) when delivered personally or by verifiable facsimile transmission, unless such delivery is made on a day that is not a Business Day, in which case such delivery will be deemed to be made on the next succeeding Business Day, (ii) on the next Business Day after timely delivery to an overnight courier and (iii) on the Business Day actually received if deposited in the U.S. mail (certified or registered mail, return receipt requested, postage prepaid), addressed as follows:

1. Exercise.

(a) Right to Exercise; Exercise Price. The Holder shall have the right to exercise this Warrant at any time and from time to time as to all or any part of the shares of Common Stock issuable hereunder (the “Warrant Shares”). The “Exercise Price” for each Warrant Share purchased by the Holder upon the exercise of this Warrant shall be equal to $0.30, subject to adjustment for the events specified in Section 5 below. The Holder may pay the Exercise Price in either of the following forms or, at the election of the Holder, a combination thereof:

(i) through a cash exercise (a “Cash Exercise”) by delivering immediately available funds, or

(ii) if, at any time following the Registration Deadline (as defined in the Registration Rights Agreement), an effective Registration Statement is not available for the resale of all of the Warrant Shares issuable hereunder at the time an Exercise Notice is delivered to the Company, through a cashless exercise (a “Cashless Exercise”). The Holder may effect a Cashless Exercise by surrendering this Warrant to the Company and noting on the Exercise Notice that the Holder wishes to effect a Cashless Exercise, upon which the Company shall issue to the Holder the number of Warrant Shares determined as follows:

X = Y x (A-B)/A

where: X = the number of Warrant Shares to be issued to the Holder;

Y = the number of Warrant Shares with respect to which this Warrant is being exercised;

A = the Trading Price (as defined in the Registration Rights Agreement) as of the Exercise Date; and

B = the Exercise Price.

For purposes of Rule 144, it is intended and acknowledged that the Warrant Shares issued in a Cashless Exercise transaction shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares required by Rule 144 shall be deemed to have been commenced, on the Issue Date.

(b) Exercise Notice. In order to exercise this Warrant, the Holder shall (i) send by facsimile transmission, at any time prior to 5:00 p.m., New York time, on the Business Day on which the Holder wishes to effect such exercise (the “Exercise Date”), to the Company an executed copy of the notice of exercise in the form attached hereto as Exhibit A (the “Exercise Notice”), (ii) deliver the original Warrant and (iii) in the case of a Cash Exercise, pay the Exercise Price to the Company by wire transfer in immediately available funds. The Exercise Notice shall also state the name or names (with address) in which the shares of Common Stock that are issuable on such exercise shall be issued. If shares are to be issued in the name of a person other than the Holder, the Holder will pay all transfer taxes payable with respect thereto.

(c) Holder of Record. The Holder shall, for all purposes, be deemed to have become the holder of record of the Warrant Shares specified in an Exercise Notice on the Exercise Date specified therein, irrespective of the date of delivery of such Warrant Shares, subject to payment of the Exercise Price. Except as specifically provided herein, nothing in this Warrant shall be construed as conferring upon the Holder hereof any rights as a shareholder of the Company, including, without limitation, the right to vote, the right to receive dividends or other distributions made to shareholders of the Company, and the right to exercise preemptive rights, prior to the Exercise Date.

(d) Cancellation of Warrant. This Warrant shall be canceled upon its exercise and, if this Warrant is exercised in part, the Company shall, at the time that it delivers Warrant Shares to the Holder pursuant to such exercise as provided herein, issue a new warrant, and deliver to the Holder a certificate representing such new warrant, with terms identical in all respects to this Warrant (except that such new warrant shall be exercisable into the number of shares of Common Stock with respect to which this Warrant shall remain unexercised); provided, however, that the Holder shall be entitled to exercise all or any portion of such new warrant at any time following the time at which this Warrant is exercised, regardless of whether the Company has actually issued such new warrant or delivered to the Holder a certificate therefor.

2. Delivery of Warrant Shares Upon Exercise. Upon receipt of an Exercise Notice pursuant to Section 1, the Company shall, no later than the close of business on the later to occur of (i) the third (3rd) Business Day following the Exercise Date set forth in such Exercise Notice and (ii) the date on which the Company has received payment of the Exercise Price and the taxes specified in Section 1(b), if any, are paid in full (a “Delivery Date”), issue and deliver or cause to be delivered to the Holder the number of Warrant Shares as shall be determined as provided herein. The Company shall effect delivery of Warrant Shares to the Holder by, as long as the Transfer Agent participates in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program (“FAST”), crediting the account of the Holder or its nominee at DTC (as specified in the applicable Exercise Notice) with the number of Warrant Shares required to be delivered, no later than the close of business on such Delivery Date. In the event that the Transfer Agent is not a participant in FAST, or if the Warrant Shares are not otherwise eligible for delivery through FAST, or if the Holder so specifies in an Exercise Notice or otherwise in writing on or before the Exercise Date, the Company shall effect delivery of Warrant Shares by delivering to the Holder or its nominee physical certificates representing such Warrant Shares, no later than the close of business on such Delivery Date.

3. Failure to Deliver Warrant Shares.

(a) In the event that the Company fails for any reason (other than as a result of the Holder’s failure to deliver the original Warrant to the Company or to pay the aggregate Exercise Price for the Warrant Shares being purchased) to deliver to the Holder the number of Warrant Shares specified in the applicable Exercise Notice on or before the Delivery Date therefor (an “Exercise Default”), and such default continues for five (5) Business Days following delivery of a written notice of such default by the Holder to the Company, the Company shall pay to the Holder payments (“Exercise Default Payments”) in the amount of (i) (N/365) multiplied by (ii) the aggregate Exercise Price of the Warrant Shares which are the subject of such Exercise Default multiplied by (iii) the lower of fifteen percent (15%) and the maximum rate permitted by applicable law (the “Default Interest Rate”), where “N” equals the number of days elapsed between the original Delivery Date of such Warrant Shares and the date on which all of such Warrant Shares are issued and delivered to the Holder. Cash amounts payable hereunder shall be paid on or before the fifth (5th) Business Day of each calendar month following the calendar month in which such amount has accrued.

(b) The Holder’s rights and remedies hereunder are cumulative, and no right or remedy is exclusive of any other. In addition to the amounts specified herein, the Holder shall have the right to pursue all other remedies available to it at law or in equity (including, without limitation, a decree of specific performance and/or injunctive relief). Nothing herein shall limit the Holder’s right to pursue actual damages for the Company’s failure to issue and deliver Warrant Shares on the applicable Delivery Date (including, without limitation, damages relating to any purchase of Common Stock by the Holder to make delivery on a sale effected in anticipation of receiving Warrant Shares upon exercise, such damages to be in an amount equal to (A) the aggregate amount paid by the Holder for the Common Stock so purchased minus (B) the aggregate amount of net proceeds, if any, received by the Holder from the sale of the Warrant Shares issued by the Company pursuant to such exercise).

4. Exercise Limitations. In no event shall the Holder be permitted to exercise this Warrant, or part thereof, if, upon such exercise, the number of shares of Common Stock beneficially owned by the Holder (other than shares which would otherwise be deemed beneficially owned except for being subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 4, would exceed 4.99% of the number of shares of Common Stock then issued and outstanding. As used herein, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules thereunder. To the extent that the limitation contained in this Section 4 applies, the submission of an Exercise Notice by the Holder shall be deemed to be the Holder’s representation that this Warrant is exercisable pursuant to the terms hereof and the Company shall be entitled to rely on such representation without making any further inquiry as to whether this Section 4 applies. The Company shall have no liability to any person if the Holder’s determination of whether this Warrant is convertible pursuant to the terms hereof is incorrect. Nothing contained herein shall be deemed to restrict the right of a Holder to exercise this Warrant, or part thereof, at such time as such exercise will not violate the provisions of this Section 4. This Section 4 may not be amended unless such amendment is agreed to in writing by the Holder and approved by the holders of a majority of the Common Stock then outstanding; provided, however, that the Holder shall have the right to waive the provisions of this Section 4 upon prior written notice to the Company following the announcement of a Major Transaction (as defined below), or otherwise upon sixty (60) days’ prior written notice to the Company.

5. Adjustments to Exercise Price; Distributions; Repurchase Right.

(a) Subdivision or Combination of Common Stock. If the Company, at any time after the Issue Date, subdivides (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) its shares of Common Stock into a greater number of shares, then after the date of record for effecting such subdivision, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company, at any time after the Issue Date, combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) its shares of Common Stock into a smaller number of shares, then, after the date of record for effecting such combination, the Exercise Price in effect immediately prior to such combination will be proportionally increased. Any adjustment made pursuant to this Section 5(a) that results in a decrease or increase in the Exercise Price shall also effect a proportional increase or decrease, as the case may be, in the number of shares of Common Stock into which this Warrant is exercisable.

(b) Distributions. If the Company shall declare or make any distribution of its assets (or rights to acquire its assets) to holders of Common Stock as a partial liquidating dividend or otherwise (including any dividend or distribution to the Company’s stockholders in cash or shares (or rights to acquire shares) of capital stock of a subsidiary) (a “Distribution”), the Company shall deliver written notice of such Distribution (a “Distribution Notice”) to the Holder at least fifteen (15) Business Days prior to the earlier to occur of (i) the record date for determining stockholders entitled to such Distribution (the “Record Date”) and (ii) the date on which such Distribution is made (the “Distribution Date”). The Holder shall be entitled, at its option (to be exercised by written notice delivered to the Company on or before the fifteenth (15^th) Business Day following the date on which a Distribution Notice is delivered to the Holder), either (A) upon any exercise of this Warrant on or after the Record Date, to be entitled to receive, on the Distribution Date (for any exercise effected prior to the Distribution Date) or the applicable Delivery Date (for any exercise effected after the Distribution Date), the amount of such assets which would have been payable to the holder with respect to the shares of Common Stock issuable upon such exercise (without giving effect to any limitations on such exercise contained in this Warrant or the Purchase Agreement) had the Holder been the holder of such shares of Common Stock on the Record Date or (B) upon any exercise of this Warrant on or after the Distribution Date, to reduce the Exercise Price applicable to such exercise by reducing the Exercise Price in effect on the Business Day immediately preceding the Record Date by an amount equal to the fair market value of the assets to be distributed divided by the number of shares of Common Stock as to which such Distribution is to be made, such fair market value to be reasonably determined in good faith by the independent members of the Company’s Board of Directors. Notwithstanding anything herein to the contrary, if the Holder does not notify the Company of whether the Holder has elected clause (A) or (B) in the preceding sentence by the date that is fifteen (15) Business Days after the date on which the Company delivers a Distribution Notice to the Holder, the Company shall have the right, exercisable upon written notice to the Holder, to determine whether clause (A) or (B) shall be applicable to exercises of this Warrant effected on or after the Distribution Date.

(c) Repurchase Right. If the Holder exercises its Repurchase Right under the Purchase Agreement, then, effective concurrently with such exercise and without any further action by or consideration from the Company or the Holder, the total number of shares of Common Stock for which this Warrant is then exercisable shall be reduced by fifty percent (50%).

6. Major Transactions. In the event of a merger, consolidation, business combination, tender offer, exchange of shares, recapitalization, reorganization, redemption or other similar event, as a result of which shares of Common Stock shall be changed into the same or a different number of shares of the same or another class or classes of stock or securities or other assets of the Company or another entity or the Company shall sell all or substantially all of its assets (each of the foregoing being a “Major Transaction”), the Company will give the Holder at least ten (10) Trading Days’ written notice prior to the earlier of (I) the closing or effectiveness of such Major Transaction and (II) the record date for the receipt of such shares of stock or securities or other assets, and the Holder shall be permitted to exercise this Warrant in whole or in part at any time prior to the record date for the receipt of such consideration and shall be entitled to receive, for each share of Common Stock issuable to the Holder upon such exercise, the same per share consideration payable to the other holders of Common Stock in connection with such Major Transaction. If and to the extent that the Holder retains this Warrant or any portion hereof following such record date, the Company will cause the surviving or, in the event of a sale of assets, purchasing entity, as a condition precedent to such Major Transaction, to assume the obligations of the Company with respect to this Warrant, with such adjustments to the Exercise Price and the securities covered hereby as may be necessary in order to preserve the economic benefits of this Warrant to the Holder.

7. Fractional Interests. No fractional shares or scrip representing fractional shares shall be issuable upon the exercise of this Warrant. If, on exercise of this Warrant, the Holder hereof would be entitled to a fractional share of Common Stock or a right to acquire a fractional share of Common Stock, the Company shall, in lieu of issuing any such fractional share, pay to the Holder an amount in cash equal to the product resulting from multiplying such fraction by the Trading Price as of the Exercise Date.

8. Transfer of this Warrant. The Holder may sell, transfer, assign, pledge or otherwise dispose of this Warrant, in whole or in part, as long as such sale or other disposition is made pursuant to an effective registration statement or an exemption from the registration requirements of the Securities Act, and applicable state securities laws, and is otherwise made in accordance with the applicable provisions of the Purchase Agreement. Upon such transfer or other disposition, the Holder shall deliver this Warrant to the Company together with a written notice to the Company, substantially in the form of the Transfer Notice attached hereto as Exhibit B (a “Transfer Notice”), indicating the person or persons to whom this Warrant shall be transferred and, if less than all of this Warrant is transferred, the number of Warrant Shares to be covered by the part of this Warrant to be transferred to each such person. Within ten (10) Business Days of receiving a Transfer Notice and the original of this Warrant, the Company shall deliver to the each transferee designated by the Holder a Warrant or Warrants of like tenor and terms for the appropriate number of Warrant Shares and, if less than all this Warrant is transferred, shall deliver to the Holder a Warrant for the remaining number of Warrant Shares.

9. Benefits of this Warrant; Headings. This Warrant shall be for the sole and exclusive benefit of the Holder of this Warrant and nothing in this Warrant shall be construed to confer upon any person other than the Holder of this Warrant any legal or equitable right, remedy or claim hereunder. The headings used in this Warrant are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

10. Loss, theft, destruction or mutilation of Warrant. Upon receipt by the Company of evidence of the loss, theft, destruction or mutilation of this Warrant, and (in the case of loss, theft or destruction) of indemnity reasonably satisfactory to the Company, and upon surrender of this Warrant, if mutilated, the Company shall execute and deliver a new Warrant of like tenor and date in replacement for the lost, stolen, destroyed or mutilated Warrant.

11. Notice or Demands. Any notice, demand or request required or permitted to be given by the Company or the Holder pursuant to the terms of this Warrant shall be in writing and shall be deemed delivered (i) when delivered personally or by verifiable facsimile transmission, unless such delivery is made on a day that is not a Business Day, in which case such delivery will be deemed to be made on the next succeeding Business Day, (ii) on the next Business Day after timely delivery to an overnight courier and (iii) on the Business Day actually received if deposited in the U.S. mail (certified or registered mail, return receipt requested, postage prepaid), addressed as follows:

Taxes.

(a) The issue of stock certificates on exercises of this Warrant shall be made without charge to the exercising Holder for any tax in respect of the issue thereof. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Warrant exercised, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the reasonable satisfaction of the Company that such tax has been paid.

(b) Notwithstanding any other provision of this Warrant or any other Transaction Document, for income tax purposes, any assignee or transferee shall agree that the Company and the Transfer Agent shall be permitted to withhold from any amounts payable to such assignee or transferee any taxes required by law to be withheld from such amounts. Unless exempt from the obligation to do so, each assignee or transferee shall, upon request, execute and deliver to the Company or the Transfer Agent, as applicable, a properly completed Form W-8 or W-9, indicating that such assignee or transferee is not subject to back-up withholding for United States Federal income tax purposes.

13. Governing Law. This Warrant shall be governed by and construed under the laws of the State of New York applicable to contracts made and to be performed entirely within the State of New York. The Company hereby irrevocably submits to the non-exclusive jurisdiction of the state and federal courts sitting in the City and County of New York for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby 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. The Company 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 it at the address in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and notice thereof.

Any waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

15. Successors and Assigns. This Warrant shall be binding upon the successors and permitted assigns of the parties. The Company may not assign its rights or obligations under this Agreement without the prior written consent of the Holder, which consent shall not be unreasonably withheld.
