2. Exercise of Warrant.

(a) Manner of Exercise.

(i) Cash Exercise. Provided that the Company has obtained Shareholder Approval of the Increase in the Authorized Common Stock (as defined in the Purchase Agreement), this Warrant may be exercised, in whole or in part, at any time or from time to time, during the period commencing as of 9:30:01 a.m., New York time, on the Initial Exercise Date and ending as of 5:30 p.m., New York time, on the Expiration Date (the “Exercise Period”), for fully paid and non-assessable shares of Common Stock (the “Warrant Shares”), for an exercise price per share equal to the Exercise Price, by delivery to the Company at its headquarters, or at such other place as is designated in writing by the Company, of:

(1) a duly executed Notice of Exercise, substantially in the form of Attachment I attached hereto and incorporated by reference herein;

(2) this Warrant; and

(3) subject to Section 2(a)(ii) below, payment of an amount in cash equal to the product of the Exercise Price multiplied by the number of Warrant Shares being purchased upon such exercise, with such payment being in the form of a wire transfer of immediately available U.S. funds to an account designated in writing by the Company.

The date on which the Company receives the Notice of Exercise, this Warrant, and the Exercise Price payable with respect to the Warrant Shares being purchased shall be deemed to be the date of exercise (the “Date of Exercise”).

(ii) Cashless Exercise. Notwithstanding the provisions of Section 2(a)(i)(3) above (requiring payment by wire transfer), the Company agrees that, if at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for, the issuance of the Warrant Shares to the Holder, then unless otherwise prohibited by applicable law, the Holder shall have the right to exercise this Warrant in full or in part on a cashless basis, computed using the following formula:

X = Y (A - B)

Where:

- 2 -

X = The number of Warrant Shares to be issued to the Holder pursuant to this cashless exercise;

Y = The number of Warrant Shares in respect of which the net issue election is made;

A = The Fair Market Value (as defined below) of one Warrant Share at the time the cashless exercise election is made; and

B = The Exercise Price then in effect at the time of such exercise.

The term “Fair Market Value” shall mean, on any given day: (A) if the class of Warrant Shares is exchange-traded, the average of the closing sales prices per share of the class of Warrant Shares for the ten (10) consecutive trading days ending on the day that is two (2) trading days prior to the applicable date of determination of Fair Market Value; or (B) if the class of Warrant Shares is not listed or admitted to trading on any securities exchange but is regularly traded in any over-the-counter market, then the average of the bid and ask prices per share of the class of Warrant Shares for the ten (10) consecutive trading days ending on the day that is two (2) trading days prior to the applicable date of determination of Fair Market Value; or (C) if the class of Warrant Shares is not traded as described in clauses (A) or (B), then the per share fair market value of the class of Warrant Shares as determined in good faith by the Company’s Board of Directors.

(b) Company Warrant Call. Commencing on a date which is 180 days after the Issue Date, the Company shall have the right, subject to satisfaction of the conditions in this Section 2(b), to cause the exercise of this Warrant (“Mandatory Exercise”). If the Company elects to require the Mandatory Exercise of this Warrant, the Company shall deliver prior written notice to the Holder at least ten (10) business days (“Mandatory Exercise Notice”) prior to the effective date (“Mandatory Exercise Effective Date”) of such Mandatory Exercise. In order to effectuate a Mandatory Exercise, the following conditions shall be satisfied as of the Mandatory Exercise Effective Date: (i) the Closing Bid Price for the twenty (20) consecutive Trading Days prior to the date of the Mandatory Exercise Notice shall be equal to or in excess of $0.45 (as adjusted for stock splits, stock combinations and the like occurring from and after the Issuance Date) and (ii) all of the Warrants issued pursuant to the Purchase Agreement are called by the Company for a Mandatory Exercise. If the Company elects to require the Mandatory Exercise of this Warrant, then the Holder must exercise all, but not less than all, of this Warrant for all of the then-remaining Warrant Shares for cash as further set forth herein. Notwithstanding anything contained in this Section 2(b) to the contrary (but subject to the last sentence of this Section 2(b)), the Company may not exercise its right under this Section 2(b) to the extent the Holder delivers a written notice to the Company stating that such exercise would result in a violation of Section 2(i)(i) (a “Blocker Notice”) or if such exercise would violate Section 2(i)(ii), then in respect of such mandatory exercise the Company shall have the right to require the Holder to exercise this Warrant for such number of Warrant Shares that may be exercised hereunder without violating either of subsection (i) or (ii) of Section 2(i). Thereafter and from time to time, the Holder shall further exercise this Warrant (so long as on any proposed date for a subsequent mandatory exercise all of the conditions described in this Section 2(b) are satisfied) in such amounts and from time to time until this Warrant is fully exercised, subject to ongoing compliance with this Section 2(b) and Section 2(i).

(c) Delivery of Certificates. Certificates for Warrant Shares purchased hereunder shall be transmitted by the transfer agent of the Company to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company (“DTC”) through its Deposit Withdrawal Agent Commission system if the Company is a participant in such system and such Warrant Shares are eligible for delivery in such a manner, and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise within three Business Days from the delivery to the Company of the Notice of Exercise, surrender of this Warrant and payment of the aggregate Exercise Price as set forth above (the

- 3 -

“Delivery Period”). This Warrant shall be deemed to have been exercised on the date on which this Warrant is surrendered and payment of the Exercise Price is received by the Company. The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date on which all of the criteria described in the immediately preceding sentence have occurred, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open. If fewer than all of the Warrant Shares purchasable under the Warrant are purchased, the Company will, upon such partial exercise, execute and deliver to the Holder a new Warrant (dated as of the Issue Date), in the same form and tenor as this Warrant, evidencing that portion of the Warrant not exercised.

(d) Intentionally Omitted.

(e) No Fractional Shares. If a fractional share of Warrant Shares would, but for the provisions of this Section 2(e), be issuable upon exercise of the rights represented by this Warrant, the Company shall round a fractional share to be delivered to Holder up to the next whole share.

(f) Buy-In. Notwithstanding anything else to the contrary contained herein, in addition to any other rights available to the Holder, if the Company fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the applicable Warrant Shares purchased upon exercise hereof or credit the Holder’s balance account with DTC, as applicable (a “Delivery Failure”), on or before the end of the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company hereunder), and if after such date the Holder purchases shares of Common Stock to deliver in satisfaction of a sale by the Holder of Warrant Shares that the Holder anticipated receiving from the Company upon exercise of this Warrant (a “Buy-In”), then the Company shall, within three Business Days after the Holder’s request, (1) pay cash to the Holder in the amount by which (x) the Holder’s total purchase price (including commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue, by (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored, or deliver to the Holder the number of Warrant Shares that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing the Securities as required pursuant to the terms hereof.

(g) No Charge to Holder Upon Issuance. The issuance of Warrant Shares upon exercise of this Warrant shall be made without charge to Holder for any issuance tax in respect thereof or other cost incurred by the Company in connection with such exercise and the related issuance of Warrant Shares (other than any transfer taxes resulting from the issuance of Warrant Shares to any person other than Holder).

(h) Reservation of Shares. During the Exercise Period, the Company shall reserve and keep available out of its authorized but unissued Common Stock equal to 125% of the number of Warrant Shares issuable upon the full exercise of this Warrant. All Warrant Shares which are so issuable shall,

- 4 -

when issued and upon the payment of the applicable Exercise Price, be duly and validly issued, fully paid and non-assessable and free from all taxes, liens and charges and not subject to the pre-emptive rights of any holder of Common Stock or any other class or series of stock of the Company. During the Exercise Period, the Company shall not take any action which would cause the number of authorized but unissued Common Stock to be less than the number of such shares required to be reserved hereunder for issuance upon exercise of this Warrant.

(i) Limitations on Exercises.

(i) Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable by the Holder hereof to the extent (but only to the extent) that after giving effect to such issuance after exercise, such Holder or any of its affiliates, as a result of such exercise, would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the 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 exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company, in both cases which are subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, any other Debentures or the Warrants) beneficially owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this Section 2(i)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this Section 2(i)(i) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which such securities shall be exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant may be exercised (in relation to other securities owned by the Holder together with any Affiliates), in each case subject to the Beneficial Ownership Limitation. No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability. To ensure compliance with this restriction, the Holder will be deemed to represent to the Company each time it delivers a Notice of Exercise that such notification has not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(i)(i), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the Company or the Company’s transfer agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant held by the Holder. The Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(i)(i), provided that the Beneficial Ownership

- 5 -

Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the Beneficial Ownership Limitation provisions of this Section 2(i)(i) shall continue to apply. Any such increase or decrease will not be effective until the 61^st day after such notice is delivered to the Company. The Beneficial Ownership Limitation provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(i)(i) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

(ii) Notwithstanding anything herein to the contrary, if the Company has not obtained Shareholder Approval (as defined in the Purchase Agreement), then (A) the Company may not issue upon exercise of this Warrant a number of shares of Common Stock, which, when aggregated with any shares of Common Stock issued on or after the Closing Date and prior to such exercise (i) in connection with the conversion of any Debentures issued pursuant to the Purchase Agreement and (ii) in connection with the exercise of any Warrants issued pursuant to the Purchase Agreement, would exceed 19.99% of the number of shares of the Company’s Common Stock outstanding on the Trading Day immediately preceding the Issue Date (subject to adjustment for forward and reverse stock splits, recapitalizations and the like) (such number of shares, the “Issuable Maximum”) and (B) the Company shall not be obligated to issue any Warrant Shares if such issuance would otherwise violate the Company’s obligations under the rules or regulations of its principal Trading Market. Each Holder shall be entitled to a portion of the Issuable Maximum equal to the quotient obtained by dividing (x) the original principal amount of the Holder’s Debenture by (y) the aggregate original principal amount of all Debentures issued on the Closing Date to all holders of Debentures. In addition, each Holder may allocate its pro-rata portion of the Issuable Maximum among Debentures and Warrants held by it in its sole discretion. Such portion shall be adjusted upward ratably in the event a Purchaser no longer holds any Debentures or Warrants and the amount of shares issued to such Purchaser pursuant to its Debentures and Warrants was less than such Purchaser’s pro-rata share of the Issuable Maximum. The Company and the Holder understand and agree that shares of Common Stock issued to and then held by the Holder as a result of exercises of Warrants shall not be entitled to cast votes on any resolution to obtain Shareholder Approval pursuant hereto.

3. Adjustments in Certain Events. The number, class, and price of Warrant Shares for which this Warrant may be exercised are subject to adjustment from time to time upon the happening of certain events as follows:

(a) Subdivisions, Combinations and Other Issuances. If the outstanding shares of the Company’s Common Stock are divided into a greater number of shares, by forward stock split or otherwise, or a dividend in stock is paid on the Common Stock, then the number of shares of Warrant Shares for which the Warrant is then exercisable will be proportionately increased and the Exercise Price will be proportionately reduced. Conversely, if the outstanding shares of Common Stock are combined into a smaller number of shares of Common Stock, by reverse stock split or otherwise, then the number of Warrant Shares for which the Warrant is then exercisable will be proportionately reduced and the Exercise Price will be proportionately increased. The increases and reductions provided for in this Section 3(a) will be made with the intent and, as nearly as practicable, the effect that neither the percentage of the total equity of the Company obtainable on exercise of the Warrants nor the price payable for such percentage upon such exercise will be affected by any event described in this Section 3(a).

- 6 -

(b) Subsequent Equity Sales. If, at any time while this Warrant is outstanding, the Company sells or grants any option to purchase, or grants any right to reprice, or otherwise dispose of or issues, any Common Stock or Common Stock Equivalents entitling any Person to acquire shares of Common Stock at a price per share that is lower than the initial Conversion Price of the Debenture (as defined in and determined in accordance with the Debenture), other than in connection with any Common Stock Equivalents outstanding on the Closing Date (such issuances collectively, a “Dilutive Issuance”) (if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at a price per share that is lower than such Conversion Price, such issuance shall be deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance), then the Exercise Price shall be reduced to the price equal to the product of (A) the then current Exercise Price of this Warrant, multiplied by (B) the quotient obtained by dividing (i) the Conversion Price of the Debenture after giving effect to the adjustment required by Section 5(c) of the Debenture by (ii) the then current Conversion Price of the Debenture (such lower price, the “Adjusted Exercise Price”). For purposes of clarity only, no adjustment in the number of Warrant Shares issuable upon exercise of this Warrant shall occur upon the adjustment to the Exercise Price pursuant to this Section 3(b). Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustment will be made under this Section 3(b) in respect of an Exempt Issuance. The Company shall notify the Holder in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalents subject to this Section 3(b), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 3(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Warrant Shares based upon the Adjusted Exercise Price on or after the date of such Dilutive Issuance, regardless of whether the Holder accurately refers to the Adjusted Exercise Price in the Notice of Exercise.

(c) Merger, Consolidation, Reclassification, Reorganization, Etc. In case of any change in the Common Stock through merger, consolidation, reclassification, reorganization, partial or complete liquidation, purchase of all or substantially all the assets of the Company, or other change in the capital structure of the Company, then, as a condition of such change, lawful and adequate provision will be made so that the Holder will have the right thereafter to receive upon the exercise of the Warrant the kind and amount of shares of stock or other securities or property to which he would have been entitled if, immediately prior to such event, he had held the number of Warrant Shares obtainable upon the exercise of the Warrant. In any such case, appropriate adjustment will be made in the application of the provisions set forth herein with respect to the rights and interest thereafter of the Holder, to the end that the provisions set forth herein will thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the exercise of the Warrant. The Company will not permit any change in its capital structure to occur unless the issuer of the shares of stock or other securities to be received by the Holder, if not the Company, agrees to be bound by and comply with the provisions of this Warrant.

(d) If securities of the Company or securities of any subsidiary of the Company are distributed pro rata to holders of Common Stock, such number of securities will be distributed to the Holder or its assignee upon exercise of its rights hereunder as such Holder or assignee would have been entitled to if this Warrant had been exercised prior to the record date for such distribution.

4. No Rights as a Stockholder. Nothing contained in this Agreement shall be construed as conferring upon the Holder any rights whatsoever as a stockholder of the Company, either at law or in

- 7 -

equity, including without limitation, or Holders the right to vote or to consent or to receive notice as a stockholder in respect of any meetings of stockholders for the election of directors the right to receive dividends or any other matter.

5. Restrictions on Transfer; Legends.

(a) Registration or Exemption Required. Assuming the accuracy of the representations and warranties of the Holder contained in herein, this Warrant has been issued in a transaction exempt from the registration requirements of the Securities Act by virtue of Section 4(a)(2) of the Securities Act and Regulation D promulgated thereunder and exempt from state registration or qualification under applicable state laws. The Holder acknowledges that he has been advised by the Company that this Warrant and the Warrant Shares issuable upon exercise thereof have not been registered under the Securities Act. Neither this Warrant nor the Warrant Shares may be pledged, transferred, sold or assigned except pursuant to an effective registration statement or an exemption to the registration requirements of the Securities Act and applicable state laws. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such transfer (i) that the Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that such transfer may be made without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the holder or transferee execute and deliver to the Company an investment letter in form and substance acceptable to the Company and (iii) that the transferee be an “accredited investor” as defined in Rule 501(a) promulgated under the Securities Act or a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act.

(b) Representations of Holder. The Holder represents and warrants that he has acquired this Warrant and will acquire the Warrant Shares for his own account for investment and not with a view to the sale or distribution thereof or the granting of any participation therein, and that he has no present intention of distributing or selling to others any of such interest or granting any participation therein. The Holder acknowledges that the Warrant and Warrant Shares must be held indefinitely unless a subsequent disposition thereof is registered under the Securities Act or registered or qualified under any applicable state securities or “blue-sky” laws or is exempt from registration and/or qualification. The Holder has no need for liquidity in its investment in the Company, and is able to bear the economic risk of such investment for an indefinite period and to afford a complete loss thereof. The Holder is an “accredited investor” as such term is defined in Rule 501 (the provisions of which are known to the Holder) promulgated under the Securities Act.

(c) Restrictive Legend. The Holder understands that until such time as the Warrant Shares have been registered under the Securities Act, or otherwise may be sold pursuant to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, this Warrant and the Warrant Shares, as applicable, shall bear a restrictive legend in substantially the form set forth on the cover page of this Warrant(and a stop-transfer order may be placed against transfer of the certificates for such securities in accordance with the applicable provisions of the Purchase Agreement).

(d) Disposition of Warrant or Warrant Shares. With respect to any offer, sale or other disposition of this Warrant or any Warrant Shares prior to registration of such Warrant Shares, the Holder agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with evidence, reasonably satisfactory to the Company (which shall include such representation of the transferee regarding investment intent as the Company may request, to the effect that such offer, sale or

- 8 -

other disposition may be effected without registration or qualification (under the Securities Act as then in effect or any federal or state securities law then in effect) of this Warrant or such Warrant Shares and indicating whether or not under the Securities Act certificates for this Warrant or Warrant Shares to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving such written notice and reasonably satisfactory evidence, the Company, as promptly as practicable but no later than three (3) days after receipt of the written notice, shall notify the Holder that the Holder may sell or otherwise dispose of this Warrant or Warrant Shares, all in accordance with the terms of the notice delivered to the Company. If the Company determines that the evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly with details thereof after such determination has been made. Notwithstanding the foregoing, any Warrant Shares may be offered, sold or otherwise disposed of in accordance with Rule 144 under the Act and in compliance with the applicable statutory resale restrictions imposed by state securities laws, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 and the applicable resale restrictions imposed by state securities laws have been satisfied. Each certificate representing this Warrant or the Warrant Shares thus transferred shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with such laws, unless pursuant to an opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer instructions to its transfer agent in connection with such restrictions.

(e) Removal of Restrictive Legends. The certificates evidencing the Warrant Shares shall not contain any legend restricting the transfer thereof: (A) while a registration statement covering the sale or resale of the Warrant Shares is effective under the Securities Act and such legend removal is permitted under applicable securities laws (including compliance with the prospectus delivery requirements of the Securities Act), or (B) following any sale of such Warrant Shares pursuant to Rule 144, or (C) if such Warrant Shares are eligible for sale under Rule 144(b)(1), or (D) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) and the Company shall have received an opinion of counsel to the Holder in form reasonably acceptable to the Company to such effect (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel to issue a legal opinion to its transfer agent if required by the transfer agent to effect the issuance of the Warrant Shares, as applicable, without a restrictive legend or removal of the legend hereunder. The Company agrees that at such time as the Unrestricted Conditions are met, it will, no later than three (3) Trading Days following the delivery by the Holder to the Company or the transfer agent of a certificate representing Warrant Shares, issued with a restrictive legend, deliver or cause to be delivered to such Holder a certificate (or electronic transfer) representing such Warrant Shares that is free from all restrictive and other legends.

6. Registration Rights. The Holder shall be entitled to all of the rights and subject to all of the obligations regarding registration of the shares of Common Stock issuable upon the exercise of this Warrant as described in the Registration Rights Agreement.

7. Notices; Adjustments.

(i) All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified; (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not, then on the next business day; (iii) two (2) Business Days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (iv) one (1) Business Day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company or to Holder, as applicable, at the respective addresses set forth on the signature page to the Purchase Agreement or at such other address(es) as they may designate, respectively, by ten (10) days advance written notice to the other party hereto.

- 9 -

(ii) Upon the occurrence of any adjustments pursuant to Sections 3(a) through 3(c) hereof, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment in accordance with the terms hereof and furnish to Holder a certificate setting forth such adjustment and showing in detail the facts upon which such adjustment is based. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, the Company shall mail to the Holder, at least ten (10) days prior to the date on which any such record is to be taken for the purpose of such dividend or distribution, a notice specifying such date. In the event of any voluntary dissolution, liquidation or winding up of the Company, the Company shall mail to the Holder, at least ten (10) days prior to the date of the occurrence of any such event, a notice specifying such date. If the approval of any stockholders of the Company shall be required in connection with any transaction contemplated by Section 3(c) above, then, the Company shall cause to be mailed to the Holder at least 10 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating the date on which such transaction is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such transaction. Notwithstanding the immediately preceding sentences, however, if the date on which the Company is obliged to provide notice hereunder to the Holders is prior to a public announcement relating to the events set forth and on such date the Company’s securities are traded or quoted on any recognized national securities exchange or quotation system, then such notice shall be provided to each Holder simultaneously with the notice provided to the Company’s common stockholders.
